24,284,666 | Okay guys, so I have a problem with WPF application. So far I managed to make a window with transparent background ( + no brush ). Also I added function, if my window is focused. So obviously my window should never been focused (because of transparency). This is working, but when I add lets say rectangle (on Canvas):
```
Rectangle testRectangleForText = new Rectangle();
testRectangleForText.Stroke = Brushes.Black;
testRectangleForText.StrokeThickness = 5;
testRectangleForText.Fill = null;
testRectangleForText.Height = 300;
testRectangleForText.Width = 300;
Canvas.SetLeft(testRectangleForText, 0);
Canvas.SetTop(testRectangleForText, 20);
myCanvas.Children.Add(testRectangleForText);
```
The rectangle is clickable and if I click on it, my app is focused (applicationFocus function display messageBox) and I don't want that. I already found solution for Win forms, but not for WPF, thats why I'm asking this here. Solution for win forms is here: [WINFORM SOLUTION](https://stackoverflow.com/questions/1524035/topmost-form-clicking-through-possible?lq=1)
Okay now example what I'm trying to achieve:
[example image](https://i.stack.imgur.com/9mLac.jpg)
So the red zone is my window (WPF APP) size. Background is transparent (obviously). Background application is notepad. We can see text and rectangle on Canvas.
Now, if I click on 1.(first) arrow, this is btw transparent area, nothing happens (thats good). If I click on 2.(second) arrow, MessageBox appear, which means that my WPF APP is focused and that is what I dont want. | 2014/06/18 | [

From here: <https://social.msdn.microsoft.com/Forums/vstudio/en-US/41ca3605-247c-4c5b-ac5d-74ce5abd7b92/making-a-window-invisible-to-mouse-events-ishittestvisiblefalse-not-working?forum=wpf>
I've figured out how to do this. The key being the WS\_EX\_TRANSPARENT flag for the window's extended style.You can set the topmost property like you normally would, then this code takes care of making the window transparent to mouse clicks:
Code Snippet
```
public const int WS_EX_TRANSPARENT = 0x00000020;
public const int GWL_EXSTYLE = (-20);
[DllImport("user32.dll")]
public static extern int GetWindowLong(IntPtr hwnd, int index);
[DllImport("user32.dll")]
public static extern int SetWindowLong(IntPtr hwnd, int index, int newStyle);
protected override void OnSourceInitialized(EventArgs e)
{
base.OnSourceInitialized(e);
// Get this window's handle
IntPtr hwnd = new WindowInteropHelper(this).Handle;
// Change the extended window style to include WS_EX_TRANSPARENT
int extendedStyle = GetWindowLong(hwnd, GWL_EXSTYLE);
SetWindowLong(hwnd, GWL_EXSTYLE, extendedStyle | WS_EX_TRANSPARENT);
}
``` | Try to set the `Focusable` attribute in your XAML-Code:
```
<Window ... Focusable="False">
< ... />
</Window>
``` |
52,067,136 | I'm sure this must've been asked before, but I couldn't find anything like that, sorry.
Let's say I have a list of numbers `[1..24]`:
```
numbers = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24]
```
I want to make a function that accepts two integers: `mynum` which is a number in the list and `modifier`. It will then find `mynum` in the list and then cycle through the list `modifier` number of positions (right if positive, left if negative). If it reaches the end of the list, it will loop to the other side.
What I want now is to basically shift the number `mynum` based on the input, within the list.
Example:
```
shift_function(2, 1) # returns 3
shift_function(23, 3) # returns 2
shift_function(4, -8) # returns 20
shift_function(15, 51) # returns 18
```
How can I cycle through the ends of a list like this?
I thought of using the `time` module to get a time with `mynum` as current hour and then add/subtract `modifier` hours to it. This will work with my `[1..24]` range but I'm looking for a more general solution to this what seems to be a simple problem.
**Edit:** To clearify further, I simply want to count through a list of numbers. If the end is reached, start over from the beginning, same backwards.
**Edit2:** I don't know how much more clear I have to be. Imagine you have big numbers on your desk: 3,4,5,6,7. And then you start at the 5 and take `modifier` steps to the right, let's say 3 steps. So you count: "six, seven, three", starting over from the beginning again. If `modifier` is negative, you count backwards. E.g. with `-4` you count: "four, three, seven, six".
I can't see how this is so hard to get. Seems like a very simple and common problem to me. | 2018/08/28 | [

| Looks like this function does what you want:
```
def shift_function(n, shift):
return numbers[(numbers.index(n) + shift) % len(numbers)]
``` | You can do this with `numpy`, using [`np.roll`](https://docs.scipy.org/doc/numpy/reference/generated/numpy.roll.html). Just be aware that the negative is actually inverse relative to what you want, so you can use `-modifier` instead:
```
import numpy as np
numbers = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24]
mynum = 4
modifier = -8
>>> np.roll(numbers,-modifier)[numbers.index(mynum)]
20
mynum = 15
modifier = 51
>>> np.roll(numbers,-modifier)[numbers.index(mynum)]
18

The short answer is "no". The long answer is longer but ends with "no" :-) ... you could get pretty close by writing a lot of code but to get the full correct answer you must do all the commit-copying steps of the rebase, at which point you might as well just run the rebase.

The `git rebase` command returns a success (zero) exit code if the rebase completes successfully, and a failure (nonzero) exit code if not. In shell script, you can just use `git rebase $args || git rebase --abort`. | You could use a custom pre-rebase hook to do any checks that you need before the rebase begins. There's a sample pre-rebase hook here: <https://github.com/git/git/blob/master/templates/hooks--pre-rebase.sample>
In the pre-rebase hook code, you could diff the changed files and check for conflicts and stop the rebase. |

`git rebase` returns a falsy status when it fails, so you could do something like
```
git rebase feature && echo "Success" || echo "fail" && git rebase --abort
```
This will, however, perform the actual rebase when it is successful.
If you want to *test* if a rebase *would* be successful without actually performing it, I'm afraid my only idea is to checkout another branch, check if the rebase is successful and switch back, for example:
```
branch=$(git branch | grep '* .*' | sed s/..//); git checkout -b $branch-rebase > /dev/null ; git rebase test-2 > /dev/null && result="Success" || result="fail" ; git rebase --abort ; git checkout $branch ; git branch -D $branch-rebase ; echo $result
```
I first remember the current branch in a variable (if anyone has a better solution for determining the current branch, let me know), switch to *branchname-rebase*, perform the rebase, checkout the original branch and delete the test branch before I echo the result.

| The closest thing to a "dry run" of a rebase would be to run the rebase from detached HEAD state (so that no refs are actually modified). So instead of
```
git rebase develop feature_X
```
you might do
```
git rebase develop `git rev-parse feature_x`
```
and check the exit status. The problems with this approach are:
1) It's time consuming. Basically for any branch that *doesn't* conflict, the entire rebase will run. (And it's hard to imagine how you could do much less work and still accurately know whether the rebase would succeed anyway.)
2) It creates redundant objects (dangling commits and their dependencies), which won't be *visible* but will nonetheless hang around taking up space in your local repo until you either knock the dangling commits out of the reflog and run `gc`, or create a fresh clone. If you do this often, the wasted space could really add up.
I'm also not sure how much utility this has. Just because `feature_X` and `feature_Y` would each rebase cleanly onto `develop`, doesn't mean that the sequence of "rebase `featureX` then rebase `featureY`" will necessarily complete cleanly. And while it doesn't seem like it should be the case, after some things I've seen recently I wouldn't be shocked to learn of some edge case where the order of rebases determines whether there's a conflict.
So at best you'll get the "low hanging fruit" - "I know for a fact these have conflicts".

There is also [readline.vim](https://github.com/ryvnf/readline.vim).

There is also [readline.vim](https://github.com/ryvnf/readline.vim).
It is a newer plug-in which focuses purely on the command-line. It also implements a larger subset of the Readline shortcuts and has the goal of implementing each shortcut exactly like in Readline.

| To see what is wrong with your approach, look at the following (admittedly not very good quickly put together in paint) diagram:
[](https://i.stack.imgur.com/C19GS.png)
You want to draw ${x}$ as a function of $y$, then do some form of rotation to get back to the standard "${y}$ as a function of ${x}$" graph - rotate each of these pictures by ${360}$ degrees in your head. You will see that at no point during the rotation do you get the other. And so there does not exist a rotation that gets you from one state to the other. As others have pointed out - you must reflect. We can get close though - a rotation by ${270}$ degrees clockwise of the "${x}$ as a function of ${y}$" diagram would give you
[](https://i.stack.imgur.com/SfhKU.png)
But this isn't the same as the "${y}$ as a function of ${x}$" graph - it's actually "${y}$ as a function of ${-x}$". Hope that helps
**Edit**: @b00n heT has made a lovely comment I'd like to just point out - the problem is that any rotation on the "${y}$ as a function of ${x}$" graph will preserve the fact that the ${x}$ axis remains to the right of the ${y}$ axis. In the "${x}$ as a function of ${y}$" graph - the $x$ axis is to the **left** of the $y$ axis - and so it is clear no rotation on one will give you the other. | after studying answers I finally conclude :

but note that, while the dates with dashes in them work with garyh's regex101.com demo, they don't work with R, keeping the month and day values, and the first dash.

| FYI: Rotating shapes and points has been implemented in [java.awt.geom.AffineTransform](http://java.sun.com/j2se/1.4.2/docs/api/java/awt/geom/AffineTransform.html) | You're performing a [2D rotational transformation](http://en.wikipedia.org/wiki/Rotation_matrix).
It ought to look something like this:
```
xnew = xold*cos(t) - yold*sin(t)
ynew = xold*sin(t) + yold*cos(t)
```
The rotation angle t must be in radians, of course. It's zero at the x-axis, and increased in the anti-clockwise direction.
Both the old and new points need to be expressed relative to the origin you're rotating about. |

| The values of `x` and `y` that are being manipulated in the `rotate` method will not be seen in the method that is calling it because [Java passes method arguments by value](http://javadude.com/articles/passbyvalue.htm).
Therefore, the `x` and `y` values that are being changed in the `rotate` method is a local copy, so once it goes out of scope (i.e. returning from the `rotate` method to its calling method), the values of `x` and `y` will disappear.
So currently, what is happening is:
```
x = 10;
y = 10;
o1 = new obj();
o1.a = 100;
rotate(x, y, obj);
System.out.println(x); // Still prints 10
System.out.println(y); // Still prints 10
```
The only way to get multiple values back from a method in Java is to pass an object, and manipulate the object that is passed in. (Actually, a copy of the reference to the object is passed in when an method call is made.)
For example, redefining `rotate` to return a `Point`:
```
public Point rotate(int x, int y, double angle)
{
// Do rotation.
return new Point(newX, newY);
}
public void callingMethod()
{
int x = 10;
int y = 10;
p = rotate(x, y, 45);
System.out.println(x); // Should print something other than 10.
System.out.println(y); // Should print something other than 10.
}
```
That said, as [Pierre suggests](https://stackoverflow.com/questions/576162/math-help-cant-rotate-something-knowing-java-would-be-a-plus/576168#576168), using the [AffineTransform](http://java.sun.com/javase/6/docs/api/java/awt/geom/AffineTransform.html) would be much easier in my opinion.
For example, creating a [`Rectangle`](http://java.sun.com/javase/6/docs/api/java/awt/Rectangle.html) object and rotating it using `AffineTransform` can be performed by the following:
```
Rectangle rect = new Rectangle(0, 0, 10, 10);
AffineTransform at = new AffineTransform();
at.rotate(Math.toRadians(45));
Shape rotatedRect = at.createTransformedShape(rect);
```
`AffineTransform` can be applied to classes which implement the [`Shape`](http://java.sun.com/javase/6/docs/api/java/awt/Shape.html) interface. A list of classes implementing `Shape` can be found in the linked Java API specifications for the `Shape` interface.

Shape rotatedRect = at.createTransformedShape(rect);
```
`AffineTransform` can be applied to classes which implement the [`Shape`](http://java.sun.com/javase/6/docs/api/java/awt/Shape.html) interface. A list of classes implementing `Shape` can be found in the linked Java API specifications for the `Shape` interface.
For more information on how to use `AffineTransform` and Java 2D:
* [Trail: 2D Graphics](http://java.sun.com/docs/books/tutorial/2d/index.html)

+ [Transforming Shapes, Text, and Images](http://java.sun.com/docs/books/tutorial/2d/advanced/transforming.html) | You're performing a [2D rotational transformation](http://en.wikipedia.org/wiki/Rotation_matrix).
It ought to look something like this:
```
xnew = xold*cos(t) - yold*sin(t)
ynew = xold*sin(t) + yold*cos(t)
```
The rotation angle t must be in radians, of course. It's zero at the x-axis, and increased in the anti-clockwise direction.
Both the old and new points need to be expressed relative to the origin you're rotating about. |
27,351,812 | I want to set a variable in a module from one calling module and want to retrieve that value inanother calling module.

Note that the main code of a module (which both your get\_data and set\_data calls are) runs when the module is loaded at compile time; if you are depending on something else that happens at run time to get the value, that won't work.
If all else fails, strip out as much of your code as you can and still have it fail and show us the compete failing case (including whatever loads Mod1 and Mod2). |

| Textual indicators abound for the eternal and immutable nature of the Torah. Besides examples provided in other answers, here are a couple more examples:
>
> Even all that the LORD hath commanded you by the hand of Moses, from the day that the LORD gave commandment, and onward throughout your generations ([*B'midbar* 15:23](http://www.mechon-mamre.org/p/pt/pt0415.htm#23)).
>
>
> And thou shalt keep His statutes, and His commandments, which I command thee this day, that it may go well with thee, and with thy children after thee, and that thou mayest prolong thy days upon the land, which the LORD thy G-d giveth thee, for ever ([*D'varim* 4:40](http://www.mechon-mamre.org/p/pt/pt0504.htm#40)).

>
>
>
Another approach, mentioned by the Rambam (*Moreh N'vuchim* 2:39), is that the perfect nature of the Torah precludes the possibility that it could be replaced with something that would necessarily be less perfect. Regarding this nature of the Torah, the Rambam cites such verses as:
>
> The law of the LORD is perfect ([*P'salms* 19:8](http://www.mechon-mamre.org/p/pt/pt2619.htm#8)).
>
>
>
More broadly speaking, other verses indicate that the Almighty's will is immutable and that He does not change His word:
>
> G-d is not a man, that He should lie; neither the son of man, that He should repent: when He hath said, will He not do it? or when He hath spoken, will He not fulfill it ([B'midbar 23:19](http://www.mechon-mamre.org/p/pt/pt0423.htm#19))?
>
>
> And also the Glory of Israel will not lie nor repent; for He is not a man, that He should repent ([Sh'mu'el I 15:29](http://www.mechon-mamre.org/p/pt/pt08a15.htm#29)).
>
>
>
The Ibn Ezra (*Sh'mos* 32:14) demonstrates that instances of the Almighty's regret as described elsewhere (e.g. *B'reishis* 6:6, *Sh'mos* 32:14, and *Sh'mu'el* I 15:11) are anthropopathic, and He does not actually change His mind:
>
> וינחם: חלילה להנחם השם, רק דברה תורה כלשון בני אדם, כמו ויעל (ברא' לה, יג), וירד (שם יא, ה), ישמח ד' במעשיו (תה' קד, לא), ויתעצב אל לבו (ברא' ו, ו). והנה שמואל אמר, וגם נצח ישראל לא ישקר ולא ינחם (ש"א טו, כט), ושם כתוב נחמתי שם, י.
>
>
> | Although all agree that the Torah, as a practical matter, will not change, there is a disagreement between the Rambam and others (e.g. Sefer HaIkkarim 3:16) if this is an inherent quality, and thus a fundamental aspect of belief, or just something that G-d decided.
In addition, within G-d's commandments, there is a concept of [ניתנה תורה, ונתחדשה הלכה](http://www.mechon-mamre.org/i/e401.htm) - when the Torah was given, there was a new Law - even according to the Rambam.
So even according the accepted view of the Rambam that the Torah is inherently eternal that does not preclude G-d from commanding something on a circumstantial or provisional basis.
One of the Rambam's proofs (Yisodei Hatorah 9:1) for the eternal nature of the Torah is [Devarim 29:28](http://www.chabad.org/library/bible_cdo/aid/9993/jewish/Chapter-29.htm#showrashi=true&v=28).

So shalt thou put away the evil from the midst of thee.

It is fairly clear from these verses that God will never change His commandment prohibiting idolatry. The oral tradition extends this to all other permanent changes (temporary changes are permitted on a case-by-case basis). | In addition to everything else stated here, the Rambam in his introduction to the last chapter of Sanhedrin, where he develops his 13 foundations of Jewish belief, explains the immutability of the Torah as the 9th foundation, and quotes the verse "You shall not add onto [the Torah] or subtract from it" (Deuteronomy 13:1) as the source of this central belief.
In Yesodei HaTorah 9:1 the Rambam also brings this verse
>
> דבר ברור ומפורש בתורה, שהיא מצוה עומדת לעולם ולעולמי עולמים: אין לה לא שינוי, ולא גירעון ולא תוספת, שנאמר "את כל הדבר, אשר אנוכי מצווה אתכם--אותו תשמרו, לעשות: לא תוסף עליו, ולא תגרע ממנו

Another approach, mentioned by the Rambam (*Moreh N'vuchim* 2:39), is that the perfect nature of the Torah precludes the possibility that it could be replaced with something that would necessarily be less perfect. Regarding this nature of the Torah, the Rambam cites such verses as:
>
> The law of the LORD is perfect ([*P'salms* 19:8](http://www.mechon-mamre.org/p/pt/pt2619.htm#8)).
>
>
>
More broadly speaking, other verses indicate that the Almighty's will is immutable and that He does not change His word:
>
> G-d is not a man, that He should lie; neither the son of man, that He should repent: when He hath said, will He not do it? or when He hath spoken, will He not fulfill it ([B'midbar 23:19](http://www.mechon-mamre.org/p/pt/pt0423.htm#19))?

>
> And also the Glory of Israel will not lie nor repent; for He is not a man, that He should repent ([Sh'mu'el I 15:29](http://www.mechon-mamre.org/p/pt/pt08a15.htm#29)).
>
>
>
The Ibn Ezra (*Sh'mos* 32:14) demonstrates that instances of the Almighty's regret as described elsewhere (e.g. *B'reishis* 6:6, *Sh'mos* 32:14, and *Sh'mu'el* I 15:11) are anthropopathic, and He does not actually change His mind:
>
> וינחם: חלילה להנחם השם, רק דברה תורה כלשון בני אדם, כמו ויעל (ברא' לה, יג), וירד (שם יא, ה), ישמח ד' במעשיו (תה' קד, לא), ויתעצב אל לבו (ברא' ו, ו). והנה שמואל אמר, וגם נצח ישראל לא ישקר ולא ינחם (ש"א טו, כט), ושם כתוב נחמתי שם, י.

39,945,881 | In class, our assignment is to create a two-dimensional array and create a tic-tac-toe game around it. I have everything done except displaying when the whole board is full and the game is a draw. I have tried a few things but I have not found the solution and I need some help... Here is my code:

int row, column;
char player = 'X';
//create 2 dimensional array for tic tac toe board

for (int i = 0; i < 3; i++){
for (int j = 0; j < 3; j++) {
board[i][j] = ch++;
}
}
displayBoard(board);
while(!winner(board) == true){
//get input for row/column
System.out.println("Enter a row and column (0, 1, or 2); for player " + player + ":");
row = in.nextInt();
column = in.nextInt();
//occupied
while (board[row][column] == 'X' || board[row][column] == 'O') {
System.out.println("This spot is occupied. Please try again");
}
//place the X
board[row][column] = player;
displayBoard(board);
if (winner(board)){
System.out.println("Player " + player + " is the winner!");
}
//time to swap players after each go.
if (player == 'O') {
player = 'X';
}
else {
player = 'O';
}
if (winner(board) == false) {
System.out.println("The game is a draw. Please try again.");

for (int i = 0; i < board.length; i++) {
for (int j = 0; j < board[i].length; j++) {

if (board[i][j] == 'O' || board[i][j] == 'X') {
return false;
}

I want output saying that the board is full when it's full but I get nothing. This is the last line of my output and as you can see, my current strategy is not working as it continues to ask for input. -->
Enter a row and column (0, 1, or 2); for player X:
2 0
X | O | X
O | O | X
X | X | O
Enter a row and column (0, 1, or 2); for player O: | 2016/10/09 | [

| First off:
```
while (board[row][column] == 'X' || board[row][column] == 'O') {
System.out.println("This spot is occupied. Please try again");
}
```
This will create a infinite loop because `row` and `column` shouldn't change you should ask for new input!
Also
```
public static Boolean winner(char[][] board){
for (int i = 0; i< board.length; i++) {
for (int j = 0; j < board[0].length; j++) {
if (board[i][j] == 'O' || board[i][j] == 'X') {
return false;
}
}
}
```
As soon you hit 'O' or 'X' you will exit the Method with a false (no winner)
What you probably want to check is if every spot is occupied
```
public static Boolean winner(char[][] board){
//Boolean which is true until there is a empty spot
boolean occupied = true;
//loop and check if there is empty space or if its a draw
for (int i = 0; i< board.length; i++) {
for (int j = 0; j < board[0].length; j++) {
//Check if spot is not 'O' or not 'X' => empty
if (board[i][j] != 'O' || board[i][j] != 'X') {
occupied = false;
}
}
}
if(occupied)
return false;
//Check if someone won
return (board[0][0] == board [0][1] && board[0][0] == board [0][2]) ||
(board[0][0] == board [1][1] && board[0][0] == board [2][2]) ||
(board[0][0] == board [1][0] && board[0][0] == board [2][0]) ||
(board[2][0] == board [2][1] && board[2][0] == board [2][2]) ||
(board[2][0] == board [1][1] && board[0][0] == board [0][2]) ||
(board[0][2] == board [1][2] && board[0][2] == board [2][2]) ||
(board[0][1] == board [1][1] && board[0][1] == board [2][1]) ||
(board[1][0] == board [1][1] && board[1][0] == board [1][2]);
}
```
This would now check if there is a winner or its a tie
```
Occupied == true == tie == return false
Winner == return true
```
But you have three states:
* Win
* Tie
* NotFinished
With the changed Method you will NOT finish the game until you win.
Reason:
```
while(!winner(board) == true)
```
This makes the game run as long as there is NO winner
(winner() will be false because everything is occupied or there is no winner)
```
while(!false==true) => while(true)
```
You could write a method similar to winner but it only checks if the board has empty spots:
```
public static Boolean hasEmptySpot(char[][] board){
//loop and check if there is empty space
for (int i = 0; i< board.length; i++) {
for (int j = 0; j < board[0].length; j++) {
if (board[i][j] != 'O' && board[i][j] != 'X') {
return true;
}
}
}
return false;
}
//New code
while(hasEmptySpot(board) || !winner(board)){
//Your code for the game here
....
}
```
this would end the game when there is no empty spot left
After you finished the game you can call winner(board) and it will return if you tied or won!
By creating `hasEmptySpot()` you could change your winner method to
```
public static Boolean winner(char[][] board){
return (board[0][0] == board [0][1] && board[0][0] == board [0][2]) ||
(board[0][0] == board [1][1] && board[0][0] == board [2][2]) ||
(board[0][0] == board [1][0] && board[0][0] == board [2][0]) ||
(board[2][0] == board [2][1] && board[2][0] == board [2][2]) ||
(board[2][0] == board [1][1] && board[0][0] == board [0][2]) ||
(board[0][2] == board [1][2] && board[0][2] == board [2][2]) ||
(board[0][1] == board [1][1] && board[0][1] == board [2][1]) ||
(board[1][0] == board [1][1] && board[1][0] == board [1][2]);
}
```
Why?
Because you finished the game and you know there are only two possible outcomes Win or Tie.
I hope this helped you a little bit.
**EDIT**
Had a logic error myself!
**First mistake:**
you still need to check if there is a winner while the game is running forgot that point!
```
while(hasEmptySpot(board) || !winner(board)){
}
```
Now this will quit the game loop when there is a winner or no empty spots is left
**Second mistake:**
In hasEmptySpot()
```
if (board[i][j] != 'O' && board[i][j] != 'X') {
return true;
```
not
```
if (board[i][j] != 'O' || board[i][j] != 'X') {
return true;
```
Fixed it in the upper examples.
I'm sorry for the inconvenience! | You could try to incorporate a new method such as the following:
```
public Boolean boardFull()
{
short count = 0;
for(short i = 0; i < 3; i++){
for(short j = 0; j < 3; j++){
if(board[i][j] == ‘O’ || board[i][j] == ’X’){
count++;
} else {
continue;
}
}
}
if(count == 9){
return true;
} else {
return false;
}
}
```
You could use an if statement to see if it returns true and then print something out if it does. |

| The most efficient way to do this is to keep a running count of how many spaces have been filled previously and increment that count each time a space is occupied. The board can be considered full when that count reaches 9.
If you're familiar with object-oriented programming, I think you'll find this easier to implement if you wrap your 2D array in a Board class.
Example:
```
public static class Board {
private char[][] spaces = new char[3][3];
private int numMoves = 0;
public void makeMove(int row, int col, char player) {
if (spaces[row][col] == 'X' || spaces[row][col] == 'O') {
System.out.println("This spot is occupied. Please try again");
} else {
spaces[row][col] = player;
numMoves++;
}
}
public boolean isFull() {
return numMoves == 9;
}
public boolean hasWinner() {
...
}
public void display() {
...
}
}
``` | You could try to incorporate a new method such as the following:
```
public Boolean boardFull()
{
short count = 0;
for(short i = 0; i < 3; i++){
for(short j = 0; j < 3; j++){
if(board[i][j] == ‘O’ || board[i][j] == ’X’){
count++;
} else {
continue;
}
}
}
if(count == 9){
return true;
} else {
return false;
}
}
```
You could use an if statement to see if it returns true and then print something out if it does. |

```
while (board[row][column] == 'X' || board[row][column] == 'O') {
System.out.println("This spot is occupied. Please try again");
}
```
This will create a infinite loop because `row` and `column` shouldn't change you should ask for new input!
Also
```
public static Boolean winner(char[][] board){
for (int i = 0; i< board.length; i++) {
for (int j = 0; j < board[0].length; j++) {
if (board[i][j] == 'O' || board[i][j] == 'X') {
return false;
}
}
}
```
As soon you hit 'O' or 'X' you will exit the Method with a false (no winner)
What you probably want to check is if every spot is occupied
```
public static Boolean winner(char[][] board){
//Boolean which is true until there is a empty spot
boolean occupied = true;
//loop and check if there is empty space or if its a draw
for (int i = 0; i< board.length; i++) {
for (int j = 0; j < board[0].length; j++) {
//Check if spot is not 'O' or not 'X' => empty
if (board[i][j] != 'O' || board[i][j] != 'X') {
occupied = false;
}
}
}
if(occupied)
return false;
//Check if someone won
return (board[0][0] == board [0][1] && board[0][0] == board [0][2]) ||
(board[0][0] == board [1][1] && board[0][0] == board [2][2]) ||
(board[0][0] == board [1][0] && board[0][0] == board [2][0]) ||
(board[2][0] == board [2][1] && board[2][0] == board [2][2]) ||
(board[2][0] == board [1][1] && board[0][0] == board [0][2]) ||
(board[0][2] == board [1][2] && board[0][2] == board [2][2]) ||
(board[0][1] == board [1][1] && board[0][1] == board [2][1]) ||
(board[1][0] == board [1][1] && board[1][0] == board [1][2]);
}
```
This would now check if there is a winner or its a tie
```
Occupied == true == tie == return false
Winner == return true
```
But you have three states:
* Win
* Tie
* NotFinished
With the changed Method you will NOT finish the game until you win.
Reason:
```
while(!winner(board) == true)
```
This makes the game run as long as there is NO winner
(winner() will be false because everything is occupied or there is no winner)
```
while(!false==true) => while(true)
```
You could write a method similar to winner but it only checks if the board has empty spots:
```
public static Boolean hasEmptySpot(char[][] board){
//loop and check if there is empty space
for (int i = 0; i< board.length; i++) {
for (int j = 0; j < board[0].length; j++) {
if (board[i][j] != 'O' && board[i][j] != 'X') {
return true;
}
}
}
return false;
}
//New code
while(hasEmptySpot(board) || !winner(board)){
//Your code for the game here
....
}
```
this would end the game when there is no empty spot left
After you finished the game you can call winner(board) and it will return if you tied or won!
By creating `hasEmptySpot()` you could change your winner method to
```
public static Boolean winner(char[][] board){
return (board[0][0] == board [0][1] && board[0][0] == board [0][2]) ||
(board[0][0] == board [1][1] && board[0][0] == board [2][2]) ||
(board[0][0] == board [1][0] && board[0][0] == board [2][0]) ||
(board[2][0] == board [2][1] && board[2][0] == board [2][2]) ||
(board[2][0] == board [1][1] && board[0][0] == board [0][2]) ||
(board[0][2] == board [1][2] && board[0][2] == board [2][2]) ||
(board[0][1] == board [1][1] && board[0][1] == board [2][1]) ||
(board[1][0] == board [1][1] && board[1][0] == board [1][2]);
}
```
Why?
Because you finished the game and you know there are only two possible outcomes Win or Tie.
I hope this helped you a little bit.
**EDIT**
Had a logic error myself!
**First mistake:**
you still need to check if there is a winner while the game is running forgot that point!
```
while(hasEmptySpot(board) || !winner(board)){
}
```
Now this will quit the game loop when there is a winner or no empty spots is left
**Second mistake:**
In hasEmptySpot()
```
if (board[i][j] != 'O' && board[i][j] != 'X') {
return true;
```
not
```
if (board[i][j] != 'O' || board[i][j] != 'X') {
return true;
```
Fixed it in the upper examples.
I'm sorry for the inconvenience! | Solution
========
The code that's not working is your `winner()` method. It is always returning `false` if there is at least one cell occupied. You could proceed based on the last part of [Nordiii's answer](https://stackoverflow.com/questions/39945881/java-tic-tac-toe-game-using-2-dimensional-array/39946445#39946445).
Extra problems
==============
### Cell-checking loop
Your code to check if a cell is occupied is going infinitely. You need to use an 'if' statement instead of a 'while' loop:
```
if(board[row][column] == 'X' || board[row][column] == 'O'){
System.out.println("This spot is occupied. Please try again");
continue;
}
```
Your old code got stuck always checking if 1 cell was occupied and it always returned `true`, which kept the loop alive and flooded your console. The `continue` statement will exit the current iteration of your other 'while' loop and start a new iteration, thus asking for new input.
### Exceptions
Man, that's a lot of uncaught exceptions! If I mess up my input, pow! The whole thing fails. Just put a `try` block for your input-checking code:
```
try {
row = in.nextInt();
column = in.nextInt();
// Attempt to place player (an ArrayOutOfBoundsException could be thrown)
if(board[row][column] == 'X' || board[row][column] == 'O'){
System.out.println("This spot is occupied. Please try again");
continue;
}
board[row][column] = player;
} catch(Exception e){
System.out.println("I'm sorry, I didn't get that.");
continue;
}
```
This attempts to execute the code inside the `try` statement, and if someone inputs something incorrect, the exception gets 'caught' and a new iteration is created. Genius! |

for (int j = 0; j < board[0].length; j++) {
//Check if spot is not 'O' or not 'X' => empty
if (board[i][j] != 'O' || board[i][j] != 'X') {
occupied = false;
}
}
}
if(occupied)
return false;
//Check if someone won
return (board[0][0] == board [0][1] && board[0][0] == board [0][2]) ||
(board[0][0] == board [1][1] && board[0][0] == board [2][2]) ||
(board[0][0] == board [1][0] && board[0][0] == board [2][0]) ||
(board[2][0] == board [2][1] && board[2][0] == board [2][2]) ||
(board[2][0] == board [1][1] && board[0][0] == board [0][2]) ||
(board[0][2] == board [1][2] && board[0][2] == board [2][2]) ||
(board[0][1] == board [1][1] && board[0][1] == board [2][1]) ||
(board[1][0] == board [1][1] && board[1][0] == board [1][2]);
}
```
This would now check if there is a winner or its a tie
```
Occupied == true == tie == return false
Winner == return true
```
But you have three states:
* Win
* Tie
* NotFinished
With the changed Method you will NOT finish the game until you win.
Reason:
```
while(!winner(board) == true)
```
This makes the game run as long as there is NO winner
(winner() will be false because everything is occupied or there is no winner)
```
while(!false==true) => while(true)
```
You could write a method similar to winner but it only checks if the board has empty spots:
```
public static Boolean hasEmptySpot(char[][] board){
//loop and check if there is empty space
for (int i = 0; i< board.length; i++) {
for (int j = 0; j < board[0].length; j++) {
if (board[i][j] != 'O' && board[i][j] != 'X') {
return true;
}
}
}
return false;
}
//New code
while(hasEmptySpot(board) || !winner(board)){
//Your code for the game here
....
}
```
this would end the game when there is no empty spot left
After you finished the game you can call winner(board) and it will return if you tied or won!
By creating `hasEmptySpot()` you could change your winner method to
```
public static Boolean winner(char[][] board){
return (board[0][0] == board [0][1] && board[0][0] == board [0][2]) ||
(board[0][0] == board [1][1] && board[0][0] == board [2][2]) ||
(board[0][0] == board [1][0] && board[0][0] == board [2][0]) ||
(board[2][0] == board [2][1] && board[2][0] == board [2][2]) ||
(board[2][0] == board [1][1] && board[0][0] == board [0][2]) ||
(board[0][2] == board [1][2] && board[0][2] == board [2][2]) ||
(board[0][1] == board [1][1] && board[0][1] == board [2][1]) ||
(board[1][0] == board [1][1] && board[1][0] == board [1][2]);
}
```
Why?
Because you finished the game and you know there are only two possible outcomes Win or Tie.
I hope this helped you a little bit.
**EDIT**
Had a logic error myself!
**First mistake:**
you still need to check if there is a winner while the game is running forgot that point!
```
while(hasEmptySpot(board) || !winner(board)){
}
```
Now this will quit the game loop when there is a winner or no empty spots is left
**Second mistake:**
In hasEmptySpot()
```
if (board[i][j] != 'O' && board[i][j] != 'X') {
return true;
```
not
```
if (board[i][j] != 'O' || board[i][j] != 'X') {
return true;
```
Fixed it in the upper examples.
I'm sorry for the inconvenience! | Although there are already some great answers I'd like to post another solution that is more generic in its logic to determine the winner. Currently you've hard-coded your some of the possible winning scenarios when you could write more generic logic for this.
As other answers have pointed out you want a method to check for unoccupied spaces in the board and this will tell you if there is a tie. I have implemented such a method in the code below along with the more generic winner logic.
Note that some methods are public to make it easier to test, they do not necessarily have to remain public.

| The most efficient way to do this is to keep a running count of how many spaces have been filled previously and increment that count each time a space is occupied. The board can be considered full when that count reaches 9.
If you're familiar with object-oriented programming, I think you'll find this easier to implement if you wrap your 2D array in a Board class.
Example:
```
public static class Board {
private char[][] spaces = new char[3][3];
private int numMoves = 0;
public void makeMove(int row, int col, char player) {
if (spaces[row][col] == 'X' || spaces[row][col] == 'O') {
System.out.println("This spot is occupied. Please try again");
} else {
spaces[row][col] = player;
numMoves++;
}
}
public boolean isFull() {
return numMoves == 9;
}
public boolean hasWinner() {
...
}
public void display() {
...
}
}
``` | Solution
========
The code that's not working is your `winner()` method. It is always returning `false` if there is at least one cell occupied. You could proceed based on the last part of [Nordiii's answer](https://stackoverflow.com/questions/39945881/java-tic-tac-toe-game-using-2-dimensional-array/39946445#39946445).
Extra problems
==============
### Cell-checking loop
Your code to check if a cell is occupied is going infinitely. You need to use an 'if' statement instead of a 'while' loop:
```
if(board[row][column] == 'X' || board[row][column] == 'O'){
System.out.println("This spot is occupied. Please try again");
continue;
}
```
Your old code got stuck always checking if 1 cell was occupied and it always returned `true`, which kept the loop alive and flooded your console. The `continue` statement will exit the current iteration of your other 'while' loop and start a new iteration, thus asking for new input.
### Exceptions
Man, that's a lot of uncaught exceptions! If I mess up my input, pow! The whole thing fails. Just put a `try` block for your input-checking code:
```
try {
row = in.nextInt();
column = in.nextInt();
// Attempt to place player (an ArrayOutOfBoundsException could be thrown)
if(board[row][column] == 'X' || board[row][column] == 'O'){
System.out.println("This spot is occupied. Please try again");
continue;
}
board[row][column] = player;
} catch(Exception e){
System.out.println("I'm sorry, I didn't get that.");
continue;
}
```
This attempts to execute the code inside the `try` statement, and if someone inputs something incorrect, the exception gets 'caught' and a new iteration is created. Genius! |

40,480,827 | In the paper [*Girshick, R* **Fast-RCNN** (ICCV 2015)](https://arxiv.org/abs/1504.08083), section "3.1 Truncated SVD for faster detection", the author proposes to use [SVD](https://en.wikipedia.org/wiki/Singular_value_decomposition) trick to reduce the size and computation time of a fully connected layer.
Given a *trained* model (`deploy.prototxt` and `weights.caffemodel`), how can I use this trick to replace a fully connected layer with a truncated one? | 2016/11/08 | [
"https://Stackoverflow.com/questions/40480827",

]
| **Some linear-algebra background**
Singular Value Decomposition ([SVD](https://en.wikipedia.org/wiki/Singular_value_decomposition)) is a decomposition of any matrix `W` into three matrices:
```
W = U S V*
```
Where `U` and `V` are ortho-normal matrices, and `S` is diagonal with elements in decreasing magnitude on the diagonal.
One of the interesting properties of SVD is that it allows to easily approximate `W` with a lower rank matrix: Suppose you truncate `S` to have only its `k` leading elements (instead of all elements on the diagonal) then
```
W_app = U S_trunc V*
```
is a rank `k` approximation of `W`.
**Using SVD to approximate a fully connected layer**
Suppose we have a model `deploy_full.prototxt` with a fully connected layer
```
# ... some layers here
layer {
name: "fc_orig"
type: "InnerProduct"
bottom: "in"
top: "out"
inner_product_param {
num_output: 1000
# more params...
}
# some more...
}
# more layers...
```
Furthermore, we have `trained_weights_full.caffemodel` - trained parameters for `deploy_full.prototxt` model.
1. Copy `deploy_full.protoxt` to `deploy_svd.protoxt` and open it in editor of your choice. *Replace* the fully connected layer with these two layers:
```
layer {
name: "fc_svd_U"
type: "InnerProduct"
bottom: "in" # same input
top: "svd_interim"
inner_product_param {
num_output: 20 # approximate with k = 20 rank matrix
bias_term: false
# more params...
}
# some more...
}
# NO activation layer here!
layer {
name: "fc_svd_V"
type: "InnerProduct"
bottom: "svd_interim"
top: "out" # same output
inner_product_param {
num_output: 1000 # original number of outputs
# more params...
}
# some more...
}
```
2. In python, a little [net surgery](https://github.com/BVLC/caffe/blob/master/examples/net_surgery.ipynb):
```
import caffe
import numpy as np
orig_net = caffe.Net('deploy_full.prototxt', 'trained_weights_full.caffemodel', caffe.TEST)
svd_net = caffe.Net('deploy_svd.prototxt', 'trained_weights_full.caffemodel', caffe.TEST)
# get the original weight matrix
W = np.array( orig_net.params['fc_orig'][0].data )
# SVD decomposition
k = 20 # same as num_ouput of fc_svd_U
U, s, V = np.linalg.svd(W)
S = np.zeros((U.shape[0], k), dtype='f4')
S[:k,:k] = s[:k] # taking only leading k singular values
# assign weight to svd net
svd_net.params['fc_svd_U'][0].data[...] = np.dot(U,S)
svd_net.params['fc_svd_V'][0].data[...] = V[:k,:]
svd_net.params['fc_svd_V'][1].data[...] = orig_net.params['fc_orig'][1].data # same bias
# save the new weights
svd_net.save('trained_weights_svd.caffemodel')
```
Now we have `deploy_svd.prototxt` with `trained_weights_svd.caffemodel` that approximate the original net with far less multiplications, and weights. | Actually, Ross Girshick's py-faster-rcnn repo includes an implementation for the SVD step: [`compress_net.py`](https://github.com/rbgirshick/py-faster-rcnn/blob/master/tools/compress_net.py).
BTW, you usually need to fine-tune the compressed model to recover the accuracy (or to compress in a more sophisticated way, see for example "[Accelerating Very Deep Convolutional Networks for Classification and Detection](https://arxiv.org/abs/1505.06798)", Zhang et al).
Also, for me scipy.linalg.svd worked faster than numpy's svd. |

59,773,783 | How can I retrieve the `std::unique_ptr` pointer that has been moved into a function when that function runs on a separate thread?
Consider the following example:

*fp_ = 23;
return std::move(fp_);

{
IntPtr foo_ptr = std::make_unique<int>(0);
foo_ptr = update(std::move(foo_ptr));
std::cout<< "data: " << *foo_ptr <<std::endl;

```
This is fine. `foo_ptr` is moved into `fp_` on the `update()` and then retrieved (moved back) to the `foo_ptr`.
How can I retrieve the `foo_ptr` if `update()` was running on a separate thread???
```
using IntPtr = std::unique_ptr<int>;
IntPtr&& update(IntPtr &&fp_)
{
*fp_ = 23;
return std::move(fp_);
}
int main()
{
IntPtr foo_ptr = std::make_unique<int>(0);
std::thread foo_thread(update,std::move(foo_ptr));
foo_thread.join();

}

| You don't.
You gave ownership of the memory to another thread. That thread now owns that memory and will delete it when it terminates. It doesn't exist after `join`, and you never moved the pointer back to the main thread.
If you want a thread to fill in some data for another thread, then either you need to use shared ownership or the producing thread should not own the memory at all (ie: you pass a raw pointer).
Or just use a `packaged_task<int(int)>`, and you don't have to (directly) allocate memory at all:
```
int update(int value)
{
return 23;
}
int main()
{
int value = 0;
std::packaged_task<int(int)> task(update);
auto future_int = task.get_future();
std::thread foo_thread(std::move(task), value);
foo_thread.join();
std::cout<< "data: " << future_int.get() <<std::endl;
}
``` | The simplest way is to just use a wrapper function that writes the result back to `foo_ptr`:
```
std::thread foo_thread([&foo_ptr]() {
foo_ptr = update(std::move(foo_ptr));
});
foo_thread.join();
std::cout<< "data: " << *foo_ptr <<std::endl;
```
Note though that between the `std::thread` constructor call and the completion of the `join()` call, the main thread must not access `foo_ptr` in any way. Doing so would be a data race. Before the constructor and after `join` this is fine, as both of these calls serve as synchronization points, but any access in between would be unsynchronized and race with the write to `foo_ptr` inside the lambda.
If this sounds too dangerous, consider an approach where the thread puts the result into a `std::promise` and the main thread then retrieves the object from a corresponding `std::future`:
```
std::promise<IntPtr> p;
std::future<IntPtr> fut = p.get_future();
std::thread foo_thread([ptr = std::move(foo_ptr), p = std::move(p)]() mutable {

73,835,838 | I came from C/C++, and used alot things like `#define OBJ_STATE_INPROCESS 2`, so that when coding actual logic you can have `state = OBJ_STATE_INPROCESS;`, and what it does become more obvious than `state = 2;`, which makes the code easier to maintain.
I wonder if there is some trick like this in C# | 2022/09/24 | [

| Though technically a different concept, in C# you can use contants and enums to avoid "magic numbers", e.g.
```
public static class Constants
{
public const string MyConst = "ThisIsMyConst";
}
public enum MyEnum
{
MyEnumValue1,
MyEnumValue2,
}
// Usage
var value = MyEnum.MyEnumValue2;
``` | You can accomplish that using constant properties, for example:
```
static class Constants
{
public const int OBJ_STATE_INPROCESS = 2
}
class Program
{
static void Main()
{
Console.WriteLine(Constants.OBJ_STATE_INPROCESS ); //prints 2
}
}

64,478,671 | As announced in Webpacks 5.0 release blog post build still works in most browsers after a few minor adjustments in `webpack.config.js`.
But it stopped working in Internet Explorer (11) because the generated output is mixed `ES6` and `ES5` and therefore incompatible with IE (see image).
As it actually leads to no successful build using a variety of babel plugins I'm asking myself if theres an "easy" way to specify ES5 as the generated output.
From beta phase of `webpack-5` I found a flag on [Medium](https://medium.com/@JayKariesch/webpack-5-beta-babel-loader-why-do-i-still-have-arrow-functions-6a22980dcae4) which seems not working anymore.
```
module.exports = {
output: {
filename: [name].js,
ecmaVersion: 5 // <- this flag
}

Is there some "webpack built in way“ in version 5.x to have ES5 as output target? | 2020/10/22 | [

| From the [webpack guide To v5 from v4](https://webpack.js.org/migrate/5/#turn-off-es2015-syntax-in-runtime-code-if-necessary), it says:
>
> By default, webpack's runtime code uses ES2015 syntax to build smaller bundles. If your build targets environments that don't support this syntax **(like IE11)**, you'll need to set `target: ['web', 'es5']` to revert to ES5 syntax (`'web'` if target environment is browser).
>
>
>
So you can try to set:
```
target: ['web', 'es5']
```
then it will convert code to ES5. | You could manually configure the features available in the webpack runtime with [`output.environment`](https://webpack.js.org/configuration/output/#outputenvironment).
However, [by default](https://webpack.js.org/configuration/target/#target) webpack 5 will honor any `browserslist` entries it finds and set the runtime to only use those features available in your target browsers. You can configure which browsers to target using any of the methods [here](https://webpack.js.org/configuration/target/#browserslist), but the easiest way is to specify a key in your `package.json`:
```
"browserslist": "ie 11"

9,771 | How can i generate the CBOR hex of a plutus smart contract. Does it requires to generate CBOR of onchain code only or both onchain and offchain?
Also if have a smart contract which requires parameters e.g. deadline. to run, then how will i be able to pass that argument with that cbor at the time of deployment of plutus smart contract.
Kindly suggest a recommended way for that and also how to interact efficiently with that CBPOR. | 2023/01/24 | [

| Basically, there are two ways:
1. After getting the transaction in the frontend, load the CBOR to CSL (cardano-serialization-lib), and proceed from there.
The workflow would be: build the transaction with cardano-cli, sign it with some random wallet stored in backend, send the signed transaction CBOR to frontend, deserialize the CBOR to CSL Transaction object, remove the witness you signed with in backend, call any wallet extension (eternl, nami..) injected signTx() method and get current user witness, add it to the CSL Transaction object and submit it with submitTx() wallet method.
This worked fine for me with Alonzo era and simple transactions, but had some problems with complicated (inline datums, plutusV2 scripts, etc.) Babbage era transactions. You kind of need to dig deep into CSL to make it work. So I chose the second, easier approach.
2. Build the transaction using cardano-cli, send it to the frontend in order to retrieve a witness, return both transaction CBOR and witness to backend, assemble the transaction and submit it.
In depth steps:
1. `cardano-cli transaction build-raw --babbage-era --cddl-format ...`
build instead of build-raw also works. Do not forget to add --cddl-format flag, in order for frontend sign() method to understand the format. Also you do not need to sign the transaction, only build it.
2. Send built transaction CBOR to frontend
3. `encodedTxVkeyWitnesses = await window.signTx(cbor, true)`
Call signTx() wallet method with received CBOR as a parameter. You will get the encdoded witness, which is basically a proof that user signed the transaction. The resulting hex string will look like this: `a10081825820cccfe2be401c85342497f6e1e4a241629790b0fb7f2af5f18441779d11f25b1f5840c38a93d63faac9335ecc2f24ead7ca2d46a6637f354ee707bb06eb8192af2fa6a676fb72f8772cd1c42b491ec6dfc798c76b61c55dc4eecab362e71ffab26305`
4. `await handleSubmit(cbor, encodedTxVkeyWitnesses)`
Call your backend from frontend, and pass the very same transaction CBOR you received from backend and recently acquired witness CBOR.
5. `$witnessCbor = substr($encodedTxVkeyWitnesses, strpos($encodedTxVkeyWitnesses,'825820'), (strlen($encodedTxVkeyWitnesses) - strpos($encodedTxVkeyWitnesses,'825820')));`
Note: example is in PHP. signTx() method returns a bit different witness structure than required by cardano-cli. You basically need to strip first 6 chars from the string. They represent data structure, in this case some nested arrays and stuff. You can look at structure differences here, by comparing both stripped and not stripped hex witness CBOR strings: <https://cbor.nemo157.com/>
6.
```
transactionCborFile = '
{
"type": "Unwitnessed Tx BabbageEra",
"description": "Ledger Cddl Format",
"cborHex": "<transaction CBOR here>"
}
';
$witnessCborFile = '
{
"type": "TxWitness BabbageEra",
"description": "Key Witness ShelleyEra",
"cborHex": "<stripped witness CBOR here>"
}
';
```
Create two files as described above containing transaction and witness CBOR, as cardano-cli assemble command require files as parameters.
7. `cardano-cli transaction assemble --tx-body-file <transaction_cbor_file_path> --witness-file <witness_cbor_file_path> --out-file tx.assembled`
Use cardano-cli assemble command to combine both transaction and witness CBOR in order to receive a signed transaction. At this point, transaction is signed and is ready to be submitted.
8. `cardano-cli transaction submit $MAGIC --tx-file tx.assembled`
That's it! | I have a different type of example that might be helpful to anyone looking for ways to sign (and build) transactions using both a browser wallet and a server side private key. Code is here <https://github.com/lley154/helios-examples/tree/main/nft-multisig>

| `lstrip` `iterates` over the result string until there is no more combination that matches the left most set of characters
A little illustration is below.
```
In [1]: "attr.title".lstrip('attr.')
Out[1]: 'itle' # Flow --> "attr." --> "t" --> Next char is 'i' which does not match any combination hence, iteration stops & end result ('itle') is returned
In [2]: "attr.tritle".lstrip('attr.')
Out[2]: 'itle' # "attr." --> "t" --> "r" --> Next char is 'i' which does not match any combination hence, iteration stops & end result ('itle') is returned
In [5]: "attr.itratitle".lstrip('attr.')
Out[5]: 'itratitle' # "attr." --> Next char is 'i' which does not match any combination hence, iteration stops & end result ('itratitle') is returned
``` | ```
"attr.title".lstrip('attr.')
```
means "remove every `a`, `t`, `t`, `r`, `.` from the left of the given string until no such character occurs.
Then it takes the given string and removes the `a`, the two `t`s, the `r`, the `.` and the `t`, as they all are contained in the given pattern.
At the `i` it stops as it is not contained in the pattern. |

| You should be running a Linux shell or similar. Quotes are parts of shell syntax. So you need to escape them.
The way you escape a character in shell depends on the software. But most of them support escaping with a backslash, single quotes or double quotes, e.g.:
```none
php script.php \'string\' 'word1 word2 word3'
php script.php "word $shell_variable"

| I was running Java 17 SDK and got this same problem. Solved this by running the WSO2 script with Java 11 SDK instead.
You can either :
1. Change your JAVA\_HOME variable value
2. Create a new environment variable pointing to Java 11 SDK and replace recursively inside the WSO2 directory JAVA\_HOME with the new environment variable you have created | This is because port 5672 is occupied at the time when the API Manager server starts up. You can have 2 options I can think of to proceed with,
1. Change the default port offset.
* You can either start the API manager server with -DportOffset=[offset] (ex- -DportOffset=1) or change the value in /repository/conf to a value other than 0 and start the server.
2. Stop the existing process of already occupied server
* Without worrying about port offset, you can run the API Manager server on 5672 port for AMQP transport.
* Search the process of occupied port (5672 in this case)
>
> netstat -nlp|grep 5672
>
>
>
Output should looks like something below
>
> tcp 0 0 0.0.0.0:5672 0.0.0.0:\* LISTEN 6187/java
>
>
>
* Kill the process
>
> kill -9 [Process\_ID]
>
>
>
(here, 6187)
Then start the server and you won't see the exception anymore. |

You can either :
1. Change your JAVA\_HOME variable value
2. Create a new environment variable pointing to Java 11 SDK and replace recursively inside the WSO2 directory JAVA\_HOME with the new environment variable you have created | There's a problem with your port 5672,this port is already in use by some other process. So shutdown your wso2 process by ps -ef|grep wso2 and then kill -9 .
Then change your port by following this link and start wso2 api manager again.

| This is because port 5672 is occupied at the time when the API Manager server starts up. You can have 2 options I can think of to proceed with,
1. Change the default port offset.
* You can either start the API manager server with -DportOffset=[offset] (ex- -DportOffset=1) or change the value in /repository/conf to a value other than 0 and start the server.
2. Stop the existing process of already occupied server
* Without worrying about port offset, you can run the API Manager server on 5672 port for AMQP transport.
* Search the process of occupied port (5672 in this case)
>
> netstat -nlp|grep 5672
>
>
>
Output should looks like something below
>
> tcp 0 0 0.0.0.0:5672 0.0.0.0:\* LISTEN 6187/java
>
>
>
* Kill the process
>
> kill -9 [Process\_ID]
>
>

(here, 6187)
Then start the server and you won't see the exception anymore. | There's a problem with your port 5672,this port is already in use by some other process. So shutdown your wso2 process by ps -ef|grep wso2 and then kill -9 .
Then change your port by following this link and start wso2 api manager again.

| This is because port 5672 is occupied at the time when the API Manager server starts up. You can have 2 options I can think of to proceed with,
1. Change the default port offset.
* You can either start the API manager server with -DportOffset=[offset] (ex- -DportOffset=1) or change the value in /repository/conf to a value other than 0 and start the server.
2. Stop the existing process of already occupied server
* Without worrying about port offset, you can run the API Manager server on 5672 port for AMQP transport.
* Search the process of occupied port (5672 in this case)
>
> netstat -nlp|grep 5672
>
>
>
Output should looks like something below
>
> tcp 0 0 0.0.0.0:5672 0.0.0.0:\* LISTEN 6187/java
>
>
>
* Kill the process
>
> kill -9 [Process\_ID]
>
>
>
(here, 6187)
Then start the server and you won't see the exception anymore. | As Tanvi and Abimaran said, Port 5672 is used for queuing. It's very common to get this error when configuring two nodes in one machine for trying cluster. If this port has been used by another application, and you can't shut that application down, then you can change
```
connectionfactory.TopicConnectionFactory = amqp://admin:admin@clientid/carbon?brokerlist='tcp://localhost:5672'
connectionfactory.QueueConnectionFactory = amqp://admin:admin@clientID/test?brokerlist='tcp://localhost:5672'
```
to another port for API manager in (/repository/config/jndi.properties). |

| I was running Java 17 SDK and got this same problem. Solved this by running the WSO2 script with Java 11 SDK instead.
You can either :
1. Change your JAVA\_HOME variable value
2. Create a new environment variable pointing to Java 11 SDK and replace recursively inside the WSO2 directory JAVA\_HOME with the new environment variable you have created | Port 5672 is needed for API Manager, from your exception trace, that port is occupied by another process.
Normally [RabbitMQ uses 5672](https://stackoverflow.com/questions/12792856/what-ports-does-rabbitmq-use), if that's the case you have to shut down that process. If you have another API Manager running on the physical node, then you have to offset the port with `-DportOffset=1` |
42,384,492 | I am getting errors and warnings while trying to bring up WSO2 API Manager 2.1.0 for the first time. [CentOS Linux release 7.3.1611 (Core)]. Excerpts are given below. I have already tried the suggestions at: [Failed to start wso2 API Manager v2.0.0 on centos 7.0](https://stackoverflow.com/questions/38948303/failed-to-start-wso2-api-manager-v2-0-0-on-centos-7-0)

Got to **C:\Program Files (x86)\RabbitMQ Server\rabbitmq\_server-3.3.4\sbin** and run
```
rabbitmq-service.bat stop
``` | You could change the default ports with an offset. So go to :
```
deployment.toml
```
and for example change the following config:
```
[server]
offset=1
```
so port no 5672 will be change to 5673. |

| I was running Java 17 SDK and got this same problem. Solved this by running the WSO2 script with Java 11 SDK instead.
You can either :
1. Change your JAVA\_HOME variable value
2. Create a new environment variable pointing to Java 11 SDK and replace recursively inside the WSO2 directory JAVA\_HOME with the new environment variable you have created | You could change the default ports with an offset. So go to :
```
deployment.toml
```
and for example change the following config:
```
[server]
offset=1
```
so port no 5672 will be change to 5673. |
42,384,492 | I am getting errors and warnings while trying to bring up WSO2 API Manager 2.1.0 for the first time. [CentOS Linux release 7.3.1611 (Core)]. Excerpts are given below.

| This is because port 5672 is occupied at the time when the API Manager server starts up. You can have 2 options I can think of to proceed with,
1. Change the default port offset.
* You can either start the API manager server with -DportOffset=[offset] (ex- -DportOffset=1) or change the value in /repository/conf to a value other than 0 and start the server.
2. Stop the existing process of already occupied server
* Without worrying about port offset, you can run the API Manager server on 5672 port for AMQP transport.
* Search the process of occupied port (5672 in this case)
>
> netstat -nlp|grep 5672
>
>
>
Output should looks like something below
>
> tcp 0 0 0.0.0.0:5672 0.0.0.0:\* LISTEN 6187/java
>
>
>
* Kill the process
>
> kill -9 [Process\_ID]
>
>
>
(here, 6187)
Then start the server and you won't see the exception anymore. | Port 5672 is needed for API Manager, from your exception trace, that port is occupied by another process.
Normally [RabbitMQ uses 5672](https://stackoverflow.com/questions/12792856/what-ports-does-rabbitmq-use), if that's the case you have to shut down that process. If you have another API Manager running on the physical node, then you have to offset the port with `-DportOffset=1` |

| I was trying from long time. RMQ was running in my system.
Got to **C:\Program Files (x86)\RabbitMQ Server\rabbitmq\_server-3.3.4\sbin** and run
```
rabbitmq-service.bat stop
``` | As Tanvi and Abimaran said, Port 5672 is used for queuing. It's very common to get this error when configuring two nodes in one machine for trying cluster. If this port has been used by another application, and you can't shut that application down, then you can change
```
connectionfactory.TopicConnectionFactory = amqp://admin:admin@clientid/carbon?brokerlist='tcp://localhost:5672'
connectionfactory.QueueConnectionFactory = amqp://admin:admin@clientID/test?brokerlist='tcp://localhost:5672'
```

| I was trying from long time. RMQ was running in my system.
Got to **C:\Program Files (x86)\RabbitMQ Server\rabbitmq\_server-3.3.4\sbin** and run
```
rabbitmq-service.bat stop
``` | Port 5672 is needed for API Manager, from your exception trace, that port is occupied by another process.
Normally [RabbitMQ uses 5672](https://stackoverflow.com/questions/12792856/what-ports-does-rabbitmq-use), if that's the case you have to shut down that process. If you have another API Manager running on the physical node, then you have to offset the port with `-DportOffset=1` |
28,013,648 | I built a layout like this in XML say "block.xml"
Now, i want to create an XML like this 
so that i can access each block as an array. Can somebody tell me how can i use block.xml as a template to generate my new xml file to be put as a UI part in android. Thank You

| In your layout xml you may use the include tag and re-use your block.xml
as:
```
<include
android:id="@+id/block1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
layout="@layout/block" />
```
And in your java code you can access views from block.xml as
```
View firstBlock = findViewById( R.id.block1 );
View blockButton = firstBlock.findViewById( R.id.someButtonId );
``` | You should inflate and add the sub layouts programmatically.

| This error raised because the `data` is a unicode/str variable, change the second line of your code to resolve your error:
```
data = json.loads(data)
```
`json.load` get a file object in first parameter position and call the `read` method of this.
Also you can call the `json` method of the response to fetch data directly:
```
response = requests.get('http://ws.audioscrobbler.com/2.0/?method=library.getartists&api_key=4c22bd45cf5aa6e408e02b3fc1bff690&user=joanofarctan&format=json')
data = response.json()
``` | [`requests.get(…).text`](http://www.python-requests.org/en/latest/api/#requests.Response.text) returns the content as a single (unicode) string. The [`json.load()`](https://docs.python.org/3/library/json.html#json.load) function however requires a file-like argument.
The solution is rather simple: Just use [`loads`](https://docs.python.org/3/library/json.html#json.loads) instead of `load`:
```
data = json.loads(data)
```
An even better solution though is to simply call [`json()`](http://www.python-requests.org/en/latest/api/#requests.Response.json) on the response object directly. So don’t use `.text` but `.json()`:
```
data = requests.get(…).json()
```
While this uses `json.loads` itself internally, it hides that implementation detail, so you can just focus on getting the JSON response. |
58,321,528 | Before posting this question, I have already read some documentation, [SO answers](https://stackoverflow.com/a/1306445/2386113) and watched some videos to understand `__stdcall`. So far I have understood that it's a calling convention and specifies to push parameters from right to left on the stack. This also signifies when to clear the stack.
But I am still not able to understand the advantage and cases where I should use `__stdcall`.
I have come across the following code, which is called when an OPC-UA client is closed. I see that this should follow the `__stdcall` calling convention but why? What may have happened if `__stdcall` was not specified for the following method?
```
OpcUa_StatusCode __stdcall opcua_client::onShutdownMessage(OpcUa_Handle hApplication, OpcUa_Handle hSession, OpcUa_String strShutdownMessage, void* extraParam)
{
opcua_client* pOpcClient = NULL;
if (extraParam)
{
try
{
pOpcClient = qobject_cast <opcua_client*>((QObject*)extraParam);
throw(55);
}
catch (int exeption)
{
}
}
OpcUa_StatusCode uStatus = OpcUa_Good;
QString strShutDownMsg = QString::fromUtf8(OpcUa_String_GetRawString(&strShutdownMessage));
bool bOK;
OpcUa_StatusCode uClientLibStatus = uClientLibStatus = strShutDownMsg.toUInt(&bOK, 16);
if (pOpcClient)
{

| `opcua_client::onShutdownMessage` looks like callback function. That is, a function that is sent to some API which calls the function at a later time. The callback function must then have the calling convention expected by the API, in this case `__stdcall`. Since `__stdcall` is the default calling convention on the Win32 platform, it does not have to be specified when building for Win32. | Function calling convention must be followed by the caller. If it is there, then there must be some caller of this function that will assume it has to be called in a specific way. This is usually important when you have a callback function.
Other than that, `stdcall` is meant to reduce code size compared to `cdecl` by moving argument cleanup code from the caller to the callee (which can use [`ret imm16`](https://www.felixcloutier.com/x86/ret) on x86).
This is an old micro optimization for IA-32 architecture. MSVC accepts `__stdcall` keyword on other architectures too, but it [doesn't do anything there](https://learn.microsoft.com/en-us/cpp/cpp/stdcall?view=vs-2019).
Check this example:
```
__declspec(noinline) int sum(int a, int b)
{
return a + b;
}
int add1(int a)
{
return sum(a, 1);
}
```
MSVC compiles this to:
```
int sum(int,int) PROC
mov eax, DWORD PTR _a$[esp-4]
add eax, DWORD PTR _b$[esp-4]
ret 0 ; this instruction will be replaced
int sum(int,int) ENDP
int add1(int) PROC
push 1
push DWORD PTR _a$[esp]
call int sum(int,int)
add esp, 8 ; this instruction will be removed
ret 0
int add1(int) ENDP
```
And version with `stdcall`:
```
__declspec(noinline) int __stdcall sum(int a, int b)
{
return a + b;
}
int add1(int a)
{
return sum(a, 1);
}
```
which compiles to:
```
int sum(int,int) PROC
mov eax, DWORD PTR _a$[esp-4]
add eax, DWORD PTR _b$[esp-4]
ret 8 ; 0 argument replaced with 8
int sum(int,int) ENDP
int add1(int) PROC
push 1
push DWORD PTR _a$[esp]
call int sum(int,int)
ret 0 ; extra instruction is missing here
int add1(int) ENDP
```
Notice how the 2nd example uses `ret 8` and the caller doesn't have an additional `add esp, 8`. |
7,846,938 | I am working with spring and tried to add a custom Annotation to an Entity-Bean.
All I want to do is, accessing the fields with the custom annotation @ runtime via reflection.
The Problem is, that although there are more than one Annotation on the fields, none of them are accessable at runtime:
```
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.FIELD)
public @interface ChangeableField {
}
```
The entity:
```
public class Order {
@NotNull
@Temporal(TemporalType.TIMESTAMP)
@DateTimeFormat(pattern = "dd:MM:yyyy HH:mm")
@ChangeableField
private Date scheduledStart;
@NotNull
@Temporal(TemporalType.TIMESTAMP)
@DateTimeFormat(pattern = "dd:MM:yyyy HH:mm")
@ChangeableField
private Date scheduledEnd;
//...
}
```
I have absolutely no idea what to do
```
Order.class.getField("scheduledStart").getAnnotation(ChangableField.class);
```
returns always null. (BTW all declared annotations on this field are null)
Maybe it has something to do with spring?
I would appreciate any help!
Thanks in advance
EDIT
----
I don't know why but now it's working properly:
```
for (Field currentField : order.getClass().getDeclaredFields()) {
if (currentField.getAnnotation(ChangeableField.class) != null

359,952 | I'm trying to make an electromagnet that's strength is constantly getting incremented by small amounts every second. I need to know, which would have a greater effect on the electromagnet's strength, amps or volts? (I know increasing the turns and/or density of the magnet wire will increase the strength, but I am looking for answers other than that particular one.) | 2018/03/06 | [

| Firstly, voltage plays no part in the strength of an electromagnet, it's only the current through the windings that generate the field. Consider a super-conducting magnet with zero resistance windings. There's no voltage, no power dissipation, and a large magnetic field.
However, most of us don't have the luxury of using a super-conductor to wind our magnets, we have to make do with a good-conductor, like copper. As it has resistance, we need to apply a voltage across it to push a current through it. This results in bad things like heating in the coil, whose temperature needs to be limited if it's to keep working.
For any given wound magnet, we do not have independent control over voltage and current. The magnet coil defines the ratio of those, it's called its resistance. If we apply a voltage, then (voltage/resistance) current flows. If we connect a current source, then the voltage across the coil responds, and becomes (resistance \* current).
The limit for both voltage and current is given by the coil's cooling. If we operate the coil for a very short time, we can increase the power supply, and allow the heat to be stored as a temperature rise in the windings, as long as we switch off before the coil overheats, to let it cool down before the next pulse. | In reality - it's both. The strength depends on the current, and the current depends on the DIFFERENCE between the applied voltage (e.g. the battery) and the INDUCED voltage (how fast the electromagnet is moving in relation to whatever strength you mean - usually a permanent magnet).
If you move or spin an electromagnet within a magnetic field, that causes (induces) voltage to flow through the coil. The faster you spin/move, the higher the induced voltage. If you spin it fast enough, that induced voltage becomes equal to the battery voltage (which means **no** current can flow at all). If you spin it faster still, it generates even more voltage than the battery, and you end up with a *negative* strength (charges the battery - otherwise known as regenerative breaking).
Most motors using electromagnets carry a "KV" rating, which tells you the speed it needs to be going to induce 1 volt (or the opposite - multiply it by your battery voltage to work out the fastest speed it can turn).
So to answer your question - you need to know how fast things are moving - if it's slow, a low voltage is fine. If it's very fast, you'll need a high voltage. After that - the current changes the strength, OR, the amount of time you turn it on for changes the strength. Normally, you cannot easily "change the current" - instead - you use PWM switching to turn it on and off at full current for short amounts of time... |

| You need to take care of a couple of things:

| The comments thread had a bunch of useful troubleshooting tips but it turned out the issue was with the browser.

* Check package installs `sudo apt-get install php5 libapache2-mod-php5` to make sure apache and the apache/php module is installed. If they are freshly installed, make sure apache is restarted with `sudo service apache2 restart`
* Make sure `mod_php5` is set up to load when Apache is started.

If not, you might want to add this line to `/etc/apache2/apache2.conf`:
```
LoadModule php5_module /usr/lib/apache2/modules/libphp5.so
```
* Check file permissions.
* `telnet 127.0.0.1 80` to do an oldschool web server test.After some output, type "GET" and enter. Also try this with "GET index.php". This checks if apache2 actually serves your processed php file
* Check the settings in Firefox and Bluefish. In bluefish go to Edit, Preferences, External Programs. Under Browsers, Mozilla & Opera's command should read: "firefox %s". In Firefox, go to Help, Troubleshooting Information, Profile Directory: Show Folder. Try to delete the mimeTypes.rdf file in the Firefox Profile Folder. | My problem was that I was running the PHP files from Bluefish, which sent them to Firefox and appeared in the URL bar as file:///var/www/html/index.php. This is incorrect for PHP files to run on the local machine. Instead, the URL should've read: localhost/index.php. This reflects my index.php file stored in /var/www/html. This is the only way on the local machine that the PHP interpreter will work. I hope this helps someone on down the road. |

849,741 | Lately I am writing (or trying) an emulator for the 6502 NES CPU.
I am learning many many things, some of them really surprise me and I was wondering what's the explanation for those, in particular, two things came to my mind
1. The existence of bugs, in particular the 6502 seems to have a bug in the indirect addressing mode, at least for the first processors (it affects the one used in the NES)
2. Unofficial operation codes: Again, really surprising that there are codes not official yet usable, some of them seem to be totally useless (like DOP and TOP which are variations of NOP), and some of them seem to be composition of other operation codes (such SAX or DCP).
The question is, how is it possible that when manufacturing millions of those CPUs, they ended up with bugs (such the indirect addressing mode) and also, why on earth would you as a manufacturer include unofficial operation codes that may be removed in following revisions? Does this happen also with newer CPUs? | 2014/12/07 | [

| My problem was that I was running the PHP files from Bluefish, which sent them to Firefox and appeared in the URL bar as file:///var/www/html/index.php. This is incorrect for PHP files to run on the local machine. Instead, the URL should've read: localhost/index.php. This reflects my index.php file stored in /var/www/html. This is the only way on the local machine that the PHP interpreter will work. I hope this helps someone on down the road. | Based on the above answers if you go into bluefish preferences and change firefox to "firefox -remote 'openURL(%p)' || firefox localhost/'%n'&" or make a new one called TestFox with that and set it to default if you want to be safe.

47,836,853 | I'm looking for a little advice regarding the best way to execute multiple ajax calls and then combine the results. My problem is that according to the documentation of the when function it will map the resulting argument differently when there are multiple arguments vs just a single argument.
<https://api.jquery.com/jquery.when/>
This resulted in code that looks like the following. The check seems ugly to me and as far as I can tell would need to be done everytime $.when.apply is used. Is there a way to pass in an array of deferreds to the when function so that the output is of a consistent shape?
```
//Returns an array of promises that are simple ajax get requests
var getEventFramesPromises = self.webServiceAdapter.getEventFrames(distinctEventFramePaths);
$.when.apply($, getEventFramesPromises).then(function () {
var eventFrames;
//Now "arguments" will either be an array with three arguments it the length of the getEventFramesPromises ===1
if (getEventFramesPromises.length === 1) {
eventFrames = [arguments[0]];
} else {
//Or it will be an array of arrays where each item in the array represents a deferred result
eventFrames = _.map(arguments, function (args) {
return args[0];
});
}});

| jQuery `$.when()` is probably the worst designed API in the jQuery set. Not only does it return a different data type based on what you pass it, but it also doesn't even accept an array as an argument which is the most common and flexible way to use it. What I'd suggest is a simple wrapper that "fixes" the design to be consistent:
```
// Takes an array of promises and always returns an array of results, even if only one result
$.all = function(promises) {
if (!Array.isArray(promises)) {
throw new Error("$.all() must be passed an array of promises");
}
return $.when.apply($, promises).then(function () {
// if single argument was expanded into multiple arguments, then put it back into an array
// for consistency
var args = Array.prototype.slice.call(arguments, 0);
if (promises.length === 1 && arguments.length > 1) {
// put arguments into an array for consistency
return [args];
} else {
return args;
}
});
};
```
And, here's a slightly different implementation that also takes the three element array that `$.ajax()` resolves to and makes it just be the single data value so your resolved value is just a simple array of single element results:
```
// jQuery replacement for $.when() that works more like Promise.all()
// Takes an array of promises and always returns an array of results, even if only one result
$.all = function (promises) {
if (!Array.isArray(promises)) {
throw new Error("$.all() must be passed an array of promises");
}
return $.when.apply($, promises).then(function () {
// if single argument was expanded into multiple arguments, then put it back into an array
// for consistency
var args = Array.prototype.slice.call(arguments, 0);
var returnVal;
if (promises.length === 1 && arguments.length > 1) {
// put arguments into an array for consistency
returnVal = [args];
} else {
returnVal = args;
}
// now make Ajax results easier to use by making it be just an array of results, not an array of arrays
//
return returnVal.map(function(item) {
// see if this looks like the array of three values that jQuery.ajax() resolves to
if (Array.isArray(item) && item.length === 3 && typeof item[2] === "object" && typeof item[2].done === "function") {
// just the data
return item[0];
} else {
return item;
}
});
});
};
``` | Not sure about why this question is getting down-voted. I think the question is reasonable and I point to the exact documentation in question. So I ended up taking Kevin's advice and wrote a quick helper function that will extract the results of the jquery calls taking into account the behavior when there is only a single value in the array.
```
function extractValuesFromPromises() {
if (arguments.length === 3 && typeof arguments[2].then === 'function') {
return [arguments[0]];
} else {
return _.map(arguments, function (args) {
return args[0];
});
}
}
```
Then in your code you can do this....
```
var getEventFramesPromises = self.webServiceAdapter.getEventFrames(distinctEventFramePaths);
$.when.apply($, getEventFramesPromises)
.then(extractValuesFromPromises)
.then(function (eventFrames) {
//Do whatever with ajax results
});

It's "working", but I need to get other field named 'seen', and that field will receive true if has t.post\_id = pv.post\_id AND user\_id = 100, or else return false or NULL
I can't do the `WHERE` in `JOIN` clause.
Thanks

| I have found a solution to the problem which works 100% of the time, however it's slightly inconvenient.
When trying to open the VBA > References, it will crash therefore I cannot find the missing reference.
My workaround is to clear all trusted documents, which brings the 'Enable Content' pop up. Before enabling content, I will go back to VBA > References, remove and re-add OLE Automation.
The next step is to save the file, enable content and you're good to go! | Steps:
1. panic
2. Repaired Microsoft Office
3. removed personal.xlsb file from XLStart to test
4. Opened blank excel, Alt + F11 to open VBA
5. Tools -> References -> Object Library
6. Search for missing objects
7. Corrected if found
8. These steps didn't resolve, so renamed the file opened in safe mode (win + R type Excel.exe /safe)
9. Updated dates, changed a few items and saved
10. Opened file normally, issue resolved.
Alternatively, try to have someone else open the file/update name and change a few things for you. the file is likely corrupt |

Alternatively, try to have someone else open the file/update name and change a few things for you. the file is likely corrupt | Try opening it in the Mac version of Excel. I tried this in last ditch desperation after no other recommendations worked (I couldn't try opening in online version because the file is password protected which isn't supported there). Mac Excel was able to open it without any complaints. I was then able to save it out just fine, and Windows (10, 64 bit- where the file was originally created) Excel was then able to read like normal. Using the various recovery methods with Windows Excel, the best I could get was a version that preserved the formulas but lost all of the VBA and all of the named ranges.
BTW, one other feature of my problem: I was working on the file for about a week. In that time, I never closed and reopened it. I did, however, save many, many times. Including saving versions in new files. I discovered the problem when I finally did close & reopen. And I discovered that every single version I had saved in the past five days was also corrupt. |

I opened my workbook in Excel online (Office 365, in the browser, which doesn't support macros anyway), saved it with a new file name (still using .xlsm file extension), and reopened in the desktop software.
