54,559,751 | I have this tables:
timelines
```
id | post_id | group_id

post\_views

| 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! | 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. |

31,630,596 | So when given two lists, how do I remove elements in one list from another using only map, filter or foldr? I can't use explicit recursion or lambda either.
The lists consist of only numbers that are sorted in ascending order.
For example, if given (list 1 2 3) and (list 1 3 5), I want to remove all of the second list's elements from the first list. The output I want is (list 2).
If given (list 4 5 6) and (list 2 3 5), I would get (list 4 6).
I'm guessing the final code would be something like:
```
(define (fn-name list-one list-two)
(filter ... list-one))
```

| Given that you're using Racket, we can write a simple solution in terms of some of the built-in abstract list functions and without using explicit `lambda`s, we only need a little help from [`SRFI-26`](http://docs.racket-lang.org/srfi/srfi-std/srfi-26.html). Try this:
```
(require srfi/26)
(define (difference lst1 lst2)
(filter-not (cut member <> lst2) lst1))
```
It works as expected:
```
(difference (list 1 2 3) (list 1 3 5))
=> '(2)
(difference (list 4 5 6) (list 2 3 5))
=> '(4 6)
``` | You use filter, but you have to curry and invert `member` so you cannot do it without `lambda`.
```scheme
(define (remove-elements needles haystack)
(filter (lambda (x) (not (member ...)))
haystack))
(define (remove-elements needles haystack)
(define (not-in-needles x)
(not (member ...)))
(filter not-in-needles haystack))
```
Both of these use `lambda` twice! Once for the `define` of `remove-elements` and once explicit / in `not-in-needles`. In your own example you use `lambda` once too since `(define (name . args) . body)` is the same as `(define name (lambda args . body))` |

11,462,673 | This question seems to have been asked multiple times but none of the solutions work for me.
I'm in my prod environment, here is what I've done:
* cleared cache before/after doing anything
* attempted commenting out the \_assetic stuff in config\_dev and ensure it isn't anywhere else (not that this should matter in prod env)
* set use\_controller to both true and false (obviously works with true but doesn't use the compiled files)
Is there anything else I'm missing? The files are generating completely fine from
`php app/console assetic:dump --env=prod --no-debug`
the file name matches that of in the error minus the route stuff. | 2012/07/13 | [

| There is no need to delete with the new consumer. Here is what the script outputs when attempting to delete:
>
> Note that there's no need to delete group metadata for the new consumer as it is automatically deleted when the last member leaves
>
>
>
That's the short answer. More details: By "metadata", two things are meant. First, just the information about the consumers and consumer groups that is stored as part of the group membership coordinator. That is automatically removed if all consumers in the group are gone.
Second, the consumer group has stored the committed offsets in a Kafka topic (when the new consumer is used. Previously these used to be stored with Zookeeper). That topic is not immediately deleted when the consumer group disappears. If the consumer group reappears again, it will find the previous offsets automatically in this topic. It can choose to use them or ignore them. If the consumer group never reappears, these stored offsets are eventually garbage collected automatically.
So in a nutshell, there is no need to delete anything when using the new consumer. | In Kafka 2.5.0, there is a Java API in the `AdminClient` called `deleteConsumerGroups` which can be used to delete individual ConsumerGroups.
You can use it as shown below:
```java
import java.util.Arrays;
import java.util.Properties;
import java.util.concurrent.ExecutionException;
import org.apache.kafka.clients.admin.*;
import org.apache.kafka.common.KafkaFuture;
public class DeleteConsumerGroups {
public static void main(String[] args) {
System.out.println("*** Starting AdminClient to delete a Consumer Group ***");
final Properties properties = new Properties();
properties.put(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
properties.put(AdminClientConfig.REQUEST_TIMEOUT_MS_CONFIG, "1000");
properties.put(AdminClientConfig.DEFAULT_API_TIMEOUT_MS_CONFIG, "5000");
AdminClient adminClient = AdminClient.create(properties);
String consumerGroupToBeDeleted = "console-consumer-65092";
DeleteConsumerGroupsResult deleteConsumerGroupsResult = adminClient.deleteConsumerGroups(Arrays.asList(consumerGroupToBeDeleted));
KafkaFuture<Void> resultFuture = deleteConsumerGroupsResult.all();
try {
resultFuture.get();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
adminClient.close();
}

| It is really a matter of taste over "better". I like the tempo gain that dxc4 gives. Usually the pawn is on c4 before Bf1-d3, but when Bf1 develops, as in your game, it loses time capturing on c4. Additionally, the Bishop sucks on c4 and will likely move yet again.
Black will have time to play c5 with a nice game. | I agree with Ywapom's answer. Will only add that it's better to keep the tension for a while and only take once you think white can favorably go c4-c5 or cxd5. Thus I'd prefer going ...c5 first and only later taking on c4. |

Black will have time to play c5 with a nice game. | If you're going to take on c4, wait until White's moved his light-squared bishop. This forces White to waste a tempo taking back since he'll be moving the bishop twice. So in that position, what Stockfish says to do is fine. After taking, you'd aim to follow up with ...c5 soon, with the aim of liquidating the centre.
That being said, you don't have to take on c4 in the first place. Another move in the position you posted is playing 6...b6, stopping any c5 ideas from White and preparing to push ...c5 yourself. A sample line:
6...b6 7.0-0 Bb7 8.Nc3 Nbd7 9.b3 c5! with a level position. |

14,516 | In a last round tie between 2 players fighting for top seed in a competition, here is what happened.
White had 18 seconds on his clock and black had 26 seconds. Black was winning. At move 56, black made a pawn push which exposed his king to a check by a dark square bishop, thus making the pawn push an illegal move. White did not take note so he raised the bishop and was about to play then he saw that the king was in check, so before he could call 'illegal' black quickly called the 'touch move rule'. Thus implying that white had to move the bishop. According to FIDE rules which call should supersede: Black's 'touch move' or white's 'illegal move'? | 2016/05/29 | [

| In standard play (each player has at least 60 minutes for all the moves) it makes no difference when the illegal moves is spotted the position must be restored to the one before the illegal move even if that was several moves ago.
In rapid or blitz Appendix A4 part 2b applies:
>
> b. An illegal move is completed once the player has pressed his clock.
> If the arbiter observes this he shall declare the game lost by the
> player, provided the opponent has not made his next move. If the
> arbiter does not intervene, the opponent is entitled to claim a win,
> provided the opponent has not made his next move.
>
>
>
Provided white has not released the bishop on a different square the claim for an illegal move stands and white wins the game.
EDIT: As of 1st January 2018 the rules for rapid and blitz have been brought into line with standard rate. In all 3 cases there is a time penalty for the first illegal move (1 minute for blitz and rapid, 2 minutes for standard) and only the second illegal move loses you the game. | From [FIDE's Laws of Chess](http://www.fide.com/component/handbook/?view=article&id=171)
7.5

Since the illegal move reverts the position back to before the "touch move" would be activated, White never touched the Bishop. |

And the jQuery script (something like this):
```
$(function() {
$('.moveable-element').hover(function() {
$(this).find('.content-panel').show();
$(this).css('border', '1px solid red');
}, function() {
$(this).find('.content-panel').hide();
$(this).css('border', '1px solid black');
}
$('.content-panel a').click(function() {
var class_name = $(this).attr("id");
$(this).parents('.moveable-element').appendTo($('#'+class_name));
}
}
```
And some parts of the CSS:
```
.content-panel {display: none; position: absolute;}
.moveable-element {border: 1px solid black; position: relative}
```
**NOTE**: I don't see the purpose of the AJAX in your question, please clarify. Also, this is very rough and for informational purposes, please don't expect it to work out of the box as is. If you want me to revise it though, I'd be happy to, just ask. | its simple to implement it in jQuery :
this simple example how to change an element class when its clicked by the users
```
<script type="text/javascript">
$('a').click(function(){
$(this).attr('class','newClass');

//mouseover
$('a').mouseover(function(){
$(this).attr('class','newClass');
});

5,557,650 | How can I get a `pchart` in a specific location on my HTML page? right now when I follow the example and use
```
$myPicture->autoOutput();
```
It just overwrites my entire page and just shows the graph.
Looking at the `pChart` source I found inside `pImage.class.php` a relevant function
```
function stroke()
{
if ( $this->TransparentBackground ) { imagealphablending($this->Picture,false); imagesavealpha($this->Picture,true); }
header('Content-type: image/png');
imagepng($this->Picture);
}
```
I tried to change it to this but it seems to return null and I'm getting a bunch of errors about
>
> Warning: imagettfbbox() [function.imagettfbbox]: Invalid font filename in\*\*
>
>

```

{
ob_start(NULL,4096);
$this->Picture;

return base64_encode(ob_get_clean();

| the easiest way is to split your project into 2 seperate files. One file holds your webpage and the other creates the image (chart). Let's name the second files chart.php
As you mentioned, it outputs only an image. What you need to do, is to embed this file into the first one, which holds the webpage.
Add `<img src="chart.php" width="x" height="y" />` within your html code.
HtH, Thor | I got it working, I extended the pImage class so I added the following function:
```
function strokeToBase64()
{
ob_start();
imagepng($this->Picture);
$contents = ob_get_contents();
ob_end_clean();
return base64_encode($contents);
}
```
Then the PHP code that uses the pChart lib invokes the function like this:
```
echo $myPicture->strokeToBase64();
```
In this way I can easily invoke Ajax calls using jQuery in the client side without having to create image files in the server as in the above posts is mentioned. |

| [`numericUpAndDown1.Value`](https://msdn.microsoft.com/en-us/library/system.windows.forms.numericupdown.value(v=vs.110).aspx) is of `decimal` type and thus you can't directly store it to `INT` and need a explicit cast
```
private int counter = (int)numericUpAndDown1.Value;
``` | Without knowning what the type of numericUpAndDown1.Value property is, you could accomplish this with int.Parse as a quick & dirty solution:
```
private int counter = int.Parse(numericUpAndDown1.Value.ToString());
```
As suggested in Rahul's answer, you can also try a direct cast in the case where numericUpAndDown1.Value is another numeric type. This can however result in run-time exceptions when the source value is outside of the acceptable range of integer values (less/greater than 2,147,483,647).
```
private int counter = (int)numericUpAndDown1.Value;
```
Since both of these can thrown an exception, you could use the int.TryParse method for safety:
```
private int counter = 0;
int.TryParse(numericUpAndDown1.Value.ToString(), out counter);
```
If you can post more code to provide some context, then there may be a better suggestion.
**Edit:**
The following app demonstrates that a direct-cast from decimal to int will in this case throw an exception:
```
using System;
namespace DecimalToIntTest {
class Program {
static void Main(string[] args) {
decimal x = 3000000000;
int y = (int)x;
Console.WriteLine(y);
Console.Read();
}
}

Sharing data between apps is what ContentProviders are for. Assuming that you know how to write a ContentProvider and access it, you can access files via ParcelFileDescriptor, which includes constants for the mode in which you create the files.
What you need now is to limit access so that not everybody can read the files through the content provider, and you do that via android permissions. In the manifest of one your apps, the one that will host the files and the content provider, write something like this:
```
<permission android:name="com.example.android.provider.ACCESS" android:protectionLevel="signature"/>
```
and in both apps add this:
```
<uses-permission android:name="com.example.android.provider.ACCESS" />
```
by using protectionLevel="signature", only apps signed by you can access your content provider, and thus your files. |

| I've just run into a similar situation. It seemed that `yarn` was only looking in the main Yarn package registry for my organization's private package. I had copied the examples from GitHub's Packages documentation for constructing your `.npmrc` file directly to the `.yarnrc` file in the project that will be consuming the app, not knowing that the formats were different (I've never had to deal with `.yarnrc` files before).
However, after updating the `.yarnrc` file with the correct format that you've mentioned above (which I also found in googling around), `yarn` successfully found the private package and installed it correctly.
As a heads up, my `yarn` version: **1.17.3**
Steps I Took
------------
1. Start new terminal session
2. `cd` to the project
3. `nvm use` (if you have a specific node version to use)
4. Add the correctly-formatted `.yarnrc` file to the project. See below for what it looks like.
5. Manually add the package and version range to the `package.json` for my private package
6. Run `npm login --registry=https://npm.pkg.github.com --scope=@MyOrg`
* See the note below on scope / org gotcha's
7. Run `yarn`
That worked for me.
### .yarnrc
```
"@myorg:registry" "https://npm.pkg.github.com"
```
**Note**: See below for a note on the org / scope name gotcha's
### Other Notes
I know that it appears that you don't have any issues with this, given your GH username / scope above, but for anyone else that comes here, the documentation on GH is a little sparse with regards to mapping your username / org name to a scope in the package name. Just remember these little gotcha's here:
* The name of your package must always be scoped to your org (or username)
+ E.g., `name: @johndturn/my-package`
* If your organization has capital letters in it, like `MyOrg`, just replace them in the name of the package in your `package.json` **and** your `.yarnrc` with lowercase
+ E.g., `name: @myorg/my-package`
+ **Note**: When authenticating with `npm login`, I still have kept the uppercase letters in the `--scope=` argument.
* The name of your package doesn't have to be the same name of the repo.
+ E.g., for a repo called `MyOrg/random-prefix.js-lib`, you can have `name: @myorg/js-lib` in your `package.json` file for the project itself. Then, installing it in other projects will look something like `@myorg/js-lib: 1.0.0`. | I'm not an expert with npm/yarn so I might be misunderstanding what is happening here, but I don't think package proxying from the npm registry works with yarn yet. Could that be related? When package proxying was released for npm I remember reading comments on Twitter from people that tried it with yarn and it didn't work.
Found the Twitter thread here:
<https://twitter.com/github/status/1171832034580451328>
>
> It doesn't work with Yarn. As soon as I change the registry url -> Couldn't find package.

| The problem I had is slightly different.
After tried what John suggested I still can't add private registry packages with `yarn` (but perfectly fine with `npm`)
Then I realise two things:
For GitHub packages, `npm` is fine with either
`registry=https://npm.pkg.github.com/my-org`
or
`@my-org:registry=https://npm.pkg.github.com`
but `yarn` only allow the latter syntax.
Docs from Github website only show the first syntax which could cause problems for yarn users.
Another thing is that if you `npm login` to the private registry but use a `.yarnrc` file in your project, yarn can't really mix your `npm` credentials with it. Although it seems behave differently on different environment.
But it would seems to be a best practice to stick with either `yarn login` + `.yarnrc`, or `npm login` + `.npmrc` (you can still use yarn to manage your packages in both cases) | I'm not an expert with npm/yarn so I might be misunderstanding what is happening here, but I don't think package proxying from the npm registry works with yarn yet. Could that be related? When package proxying was released for npm I remember reading comments on Twitter from people that tried it with yarn and it didn't work.
Found the Twitter thread here:

| I've just run into a similar situation. It seemed that `yarn` was only looking in the main Yarn package registry for my organization's private package. I had copied the examples from GitHub's Packages documentation for constructing your `.npmrc` file directly to the `.yarnrc` file in the project that will be consuming the app, not knowing that the formats were different (I've never had to deal with `.yarnrc` files before).
However, after updating the `.yarnrc` file with the correct format that you've mentioned above (which I also found in googling around), `yarn` successfully found the private package and installed it correctly.
As a heads up, my `yarn` version: **1.17.3**
Steps I Took
------------
1. Start new terminal session
2. `cd` to the project
3. `nvm use` (if you have a specific node version to use)
4. Add the correctly-formatted `.yarnrc` file to the project. See below for what it looks like.
5. Manually add the package and version range to the `package.json` for my private package
6. Run `npm login --registry=https://npm.pkg.github.com --scope=@MyOrg`
* See the note below on scope / org gotcha's
7. Run `yarn`
That worked for me.
### .yarnrc
```
"@myorg:registry" "https://npm.pkg.github.com"
```
**Note**: See below for a note on the org / scope name gotcha's
### Other Notes
I know that it appears that you don't have any issues with this, given your GH username / scope above, but for anyone else that comes here, the documentation on GH is a little sparse with regards to mapping your username / org name to a scope in the package name. Just remember these little gotcha's here:
* The name of your package must always be scoped to your org (or username)
+ E.g., `name: @johndturn/my-package`
* If your organization has capital letters in it, like `MyOrg`, just replace them in the name of the package in your `package.json` **and** your `.yarnrc` with lowercase
+ E.g., `name: @myorg/my-package`
+ **Note**: When authenticating with `npm login`, I still have kept the uppercase letters in the `--scope=` argument.
* The name of your package doesn't have to be the same name of the repo.
+ E.g., for a repo called `MyOrg/random-prefix.js-lib`, you can have `name: @myorg/js-lib` in your `package.json` file for the project itself. Then, installing it in other projects will look something like `@myorg/js-lib: 1.0.0`. | The problem I had is slightly different.
After tried what John suggested I still can't add private registry packages with `yarn` (but perfectly fine with `npm`)
Then I realise two things:
For GitHub packages, `npm` is fine with either
`registry=https://npm.pkg.github.com/my-org`

**such as we can get both the IP and the user-agent with `awk`?**
Using `awk -F'["]'` didn't seem to work.

| You need to include the space in your character class:
```
echo 'word1 word2"word2 word4"word5' |
awk -F '[ "]' '{ for (i = 1; i <= NF; ++i) { print $i } }'
``` | You want the IP address and the user agent.
The IP address is the second whitespace-delimited word. It will be in `$2` in `awk` with the default value of `FS`.
The user agent is the string in the last double quoted substring. You can get at that by deleting the last double quote, and then deleting everything up to what's now the last double quote.
With `awk`:
```
awk '{ ip = $2; sub("\"$",""); sub(".*\"",""); ua = $0; print ip; print ua }'
```
or, slightly shorter,
```
awk '{ ip = $2; sub("\"$",""); sub(".*\"",""); print ip; print }'
```
With `sed`:
```
sed -e 'h' -e 's/[^ ]* //;s/ .*//p' \
-e 'g' -e 's/"$//;s/.*"//'
```
This first saves the line in the hold space (`h`), then extracts the IP number by deleting up to the first space and then from the (now) first space. This isolates the IP number, which is printed. Then the saved line is retrieved (`g`) and the same procedure as in the `awk` code is applied, i.e. delete the last double quote, and then everything up to the (now) last double quote.
Both commands print the IP number on one line, followed by the user agent string on the next. |

| You can use [Integer.parseInt(String, int)](http://docs.oracle.com/javase/8/docs/api/java/lang/Integer.html#parseInt-java.lang.String-int-) to convert a String representing binary data to an int:
```
int value = Integer.parseInt("111111110000000010101010", 2);
```
You can then shift using the [bit shift operators](http://docs.oracle.com/javase/tutorial/java/nutsandbolts/op3.html):
>
> The signed left shift operator "<<" shifts a bit pattern to the left, and the signed right shift operator ">>" shifts a bit pattern to the right. The bit pattern is given by the left-hand operand, and the number of positions to shift by the right-hand operand. The unsigned right shift operator ">>>" shifts a zero into the leftmost position, while the leftmost position after ">>" depends on sign extension.
>
>
> | An alternative is to use [Java 7's binary literal notation](http://docs.oracle.com/javase/7/docs/technotes/guides/language/binary-literals.html), to avoid the problem in the first place...
```
int value = 0b111111110000000010101010;
int shifted = value >> 16;

19,181,359 | I'm using a variable to store a count and am trying to fire off a stored procedure a number of times, iterating the number each time. However, I'm having problems with the syntax I need to use. Here's what I have so far:

Say, if you have the following file,
```
$cat file

you can use the following to remove the duplicate lines:
```
$awk '!x[$1]++' file

| The expression is parsed as
```
!(x[$(1)]++)
```
So, from the inside out, it's:
* Take field 1 of the current input line, `$(1)` (note that `$` is an operator in AWK, unlike in Perl).
* Index `x` with the value of field 1; if `x` is an unbound variable, bind it to a new associative array.
* Post-increment `x[$(1)]`; a rule similar to the one in C applies, so the value of the expression is that of `x[$(1)]` prior to the increment, which will be zero if `x[$(1)]` has not yet been assigned a value.
* Negate the value of the previous, which will yield truth when `x[$(1)]` is zero.
* Actually do the increment so that `x[$(1)]` gets a non-zero value. So, the next time, `x[$(1)]` for the same value of `$(1)` will return 1.
This expression is then evaluated for every line in the input and determines whether the implied default action of `awk` should be executed, which is to echo the line to `stdout`. | In AWK arrays are associative, so the first column or first field of each line, `$1`, is used as an index for the array `x`. |

| As per my comment…
The main issue with your code is that you have not followed the guidance for the use of the `Set` command. Opening a Command Prompt window and entering **`set /?`**, should have been sufficient to learn how to use that command, *from the output*.
Currently your variable is `%print_time %` not `%print_time%`, because spaces either side of the **`=`** are included in both the variables name and value. Effectively you need to change `set print_time = %mydate%_%mytime%` to `set print_time=%mydate%_%mytime%`.
In addition, it is best practice to use quotation marks to protect spaces and other 'poison' characters in your strings. When it come to setting a variable, the recommended syntax is `Set "VariableName=Variable Value"`, so you should be using, `Set "print_time=%mydate%_%mytime%"`. Also although not necessary with the provided path, it is safer to enclose the variable `%DIR%` in quotation marks too, *(this would mean that any change in the destination path, perhaps introducing spaces or ampersands, would not affect the rest of the code)*. You should therefore do that in your `MkDir` and `mongodump` command lines, thus:
```bat
@Echo Off
For /F "Tokens=2-4Delims=/ " %%A In ('Date /T')Do Set "MyDate=%%C-%%A-%%B"
For /F "Delims=:" %%A In ('Time /T')Do Set "MyTime=%%A"
Set "print_time=%MyDate%_%MyTime%"
Set "DIR=%print_time%"
Set "DEST=D:\MongoDB\db_backup\%DIR%"
MkDir "%DEST%" 2>NUL
mongodump -h 127.0.0.1:27017 -d DW -u [user] -p [password] -o "%DEST%"
```
The methods you used in creating your date and time string is not very robust, because the results of `Date` and `Time` with their `/T` option are Locale/PC/User dependent. I would suggest you use a method which isn't, so offer a solution which uses `RoboCopy` instead. Additionally, the following defines only one variable in achieving your goal, instead of five:
```bat
@Echo Off
Set "DEST="
For /F "Tokens=1-4Delims=/: " %%A In ('RoboCopy /NJH /L "\|" Null')Do If Not Defined DEST Set "DEST=D:\MongoDB\db_backup\%%A-%%B-%%C_%%D"
If Not Defined DEST GoTo :EOF
MD "%DEST%" 2>NUL
mongodump -h 127.0.0.1:27017 -d DW -u [user] -p [password] -o "%DEST%"
``` | Try the following this works as expected for me.
I suspect that you have a space in your original method, and this is just taking your code removing redundant parts and using Quotes around variables to make sure it isn't happening.
```
@ECHO OFF
SET "_UN=YourUserName"
SET "_PW=YourPassword"
SET "_MongoDBIPPort=127.0.0.1:27017"
SET "_MongoDB=DW"
SET "_MongoBackupRoot=D:\MongoDB\db_backup"
FOR /F "Tokens=1-7 delims=MTWFSmtwfsouehrandit:-\/. " %%A IN ("%DATE% %TIME: =0%") DO (
FOR /F "Tokens=2-4 Skip=1 Delims=(-)" %%a IN ('ECHO.^| DATE') DO (
SET "%%~a=%%~A" & SET "%%~b=%%~B" & SET "%%~c=%%~C" & SET "HH=%%~D" & SET "Mn=%%~E" & SET "SS=%%~F" & SET "Ms=%%~G"
)
)
SET "_PrintTime=%yy%-%mm%-%dd%_%HH%.%Mn%"
ECHO(_PrintTime = "%_PrintTime%"
SET "_Dest=%_MongoBackupRoot%\%_PrintTime%"
ECHO(Dest Directory = "%_Dest%"
IF NOT EXIST "%_Dest%" (
MD "%_Dest%"
)
mongodump -h %_MongoDBIPPort% -d %_MongoDB% -u %_UN% -p %_PW% -o "%_Dest%"
```
As your original code did not give me the issue you encountered, it again leads to to believe there may have some errant spaces in your variable declarations or other non printable characters which I am not able to receive through Stack Exchange.
Note: I changed the code to no longer rely on the date being a particular format so that the code will run the same on my machine as yours as I use a different date format then you do, so I felt it was better to post code which should work for either of us.
Sorry looks like I left this up mid-edit when I rushed out yesterday, and did not post it at that time.
Hope that helps! :) |

| Same thing bothering me. As far as I can tell, there is no 'native' Finder solution.
However, as a (belated) suggestion to OP, or anyone else with the same problem, here's how I solved it for myself -- sort of a 'hack', but better than Finder default behavior:
Use some keyboard customization software (I'm using Karabiner), and define a (user activated) shortcut that triggers two other keyboard shortcuts that are executed automatically, and in sequence. The shortcuts that do the trick are: (1) Reveal in Finder, (2) Merge all windows.
Details: "Reveal in Finder" is already bound to a shortcut natively (cmd-R), but "Merge all windows" is not afaik. Since adding menu items in Karabiner is a bit tricky, probably the easiest way is to assign a shortcut to "Merge..." in System Preferences -> Keyboard -> Shortcuts -> App shortcuts. I picked cmd-shift-M. You can then make use of this (OSX) shortcut in the definition of a Karabiner shortcut.
In Karabiner, I then defined a custom shortcut (cmd-R), triggering cmd-R and cmd-shift-M.
The effect is pretty close to what I wanted to see in the first place: in a Finder search tab/window, I select an item, press cmd-R, which reveals the item in a new window, which is immediately merged into the existing window as a new tab.
Focus remains on main window, the new tab goes to the end of the tab bar, and I can continue revealing other items immediately without having to cycle tabs.
The one thing that still bothers me: the "merge windows" animation is slow-ish, and I can't find a way to speed it up (or disable it).
Like I said, not perfect perhaps, but it's reasonably close to what I had in mind. | Xtra Finder does this automatically and I had been using it. However I found it slow after upgrading to Yosemite - like many other things - so I uninstalled it to give the Finder another chance with the hope it had improved. Sadly it remains really limited and like you, I use Spotlight to navigate to folders and find it infuriating that it keeps launching new windows.
I would also love a fix to this.
BTW XtraFinder is free and has other benefits like using the delete key to delete a file |

| As the bus may be in any state, it may not even be possible to use the TWI peripheral to send anything, not even start bit.
So you must switch the I2C peripheral off so you can just send the wanted sequence by bit-banging the GPIO pins with software. Just remember that you must never output logic high, only logic low or input. | Is the spec really calling for you to send 9 bits over I2C when the interface is generally byte oriented? (Could be so as this is a reset operation, although it is unusual. I would first check the datasheet.)
If it is so, the best way is probably to take over the port pins and write a routine to bit bash this, then release the port. It's a routine that would only be used exceptionally, so no harm with it, and bit bashing is not too hard with I2C. In this case you don't care if it is a bit slower than normal operations. |
55,725,618 | I am trying to follow the latest Google's good practises implementing a single Activity Application with Navigation Components.
However after reading the whole Navigation documentation I still think there are a lot of cases that they don't address.
For example, How should I implement the following case:
[](https://i.stack.imgur.com/3V010.png)
* App starts in a splash screen. Then after some loading goes to the News Fragment.
**Note:** Splash Screen should pop from the backstack, since it shouldn't be acessible anymore.
* A Navigation Drawer should be available in all fragments of Section 1, allowing the user to navigate between fragments in this section.
* However some fragments in the section can navigate to a new area which should have a back button (not a drawer). | 2019/04/17 | [

| Have you tried creating a new project with selected `Navigation Drawer Activity`?
**1. Drawer**
In XML you should add for this activity a `FrameLayout` that will hold fragments. Then you can start using this activity as a container for your fragments and on `DrawerMenuItem` click, you load a particular fragment.
I use this method to reload fragments:
```
public void replaceFragment (Fragment fragment, Bundle args){
fragment.setArguments(args);
getSupportFragmentManager().beginTransaction().replace(R.id.container, fragment).commit();
}
```
and call it like this from activity:
```
replaceFragment(Fragment.newInstance(), args)
```
Then you have your drawer available in all fragments.
**2. Details screen with back arrow**
As for another screen with for example Article details, you could start activity with details:
`startActivity(new Intent(packageContext, ArticleDetailsActivity.class));`
Then there is no drawer and you have a back button.
**3. Splash**
As for creating a "good" splash screen Google "Android splash screen the right way", there are posts on medium (by Sylvain Saurel) or bignerdranch (by Chris Stewart) that cover this topic. | Use `DestinatedChangedListener` on the `nav controller` to `lock` and `unlock` the drawer mode. |

| You should try to keep your interface lean, especially if you might want to implement different container types, e.g. array-based and linked-list. If you provide some basic methods in all your containers, you can create external algorithms which perform certain tasks but which can work on all containers:
```
void Replace(const std::size_t Start, const std::size_t End, const T Value);
```
could become
```
template<class ContainerType>
void ReplaceAllElementsInContainer(ContainerType& Container, const std::size_t Start, const std::size_t End, const T Value);
```
outside the classes. If you don't do this, you have to write all those methods In all your containers.
Another possibility is to use the template method pattern (not related to C++ templates) and write all these methods in a base class (which defines the basic methods as pure virtual and calls them from the implemented "convenience" methods).

In short, keep the most logic out of your container classes. | I had a similar case like these. My suggestion is, that you have 2 "base classes" or "super classes".
The first class, very general class, represents the "conceptual root" for all containers classes, almost not methods, similar to an interface, and should be like:
---
containers.hpp
---------------
```
class Container
{
protected:
int GetValue();
void SetValue(int newValue);
size_t GetSize();
void Resize(size_t);
};
```
---
The second class, starts to be a little less conceptual and more "real world":
---
mcontainers.hpp
----------------
```
#include "containers.hpp";
class MethodContainer: public Container
{
protected:
void Replace(const std::size_t Start, const std::size_t End, const T Value);
void Replace(const std::size_t Start, const std::size_t End, const MyClass Other);
void Insert(const std::size_t Index, const T Value);
void Insert(const std::size_t Index, const MyClass Other);
void Delete(const std::size_t Index);
void Delete(const std::size_t Start, const std::size_t End);
```
}
--
And, finally, some classes that are concrete:
---
stacks.hpp
-----------
```
#include "containers.hpp";
#include "mcontainers.hpp";
#define pointer void*
class Stack: public MethodContainer
{
public:
// these methods use "mcontainer::Insert", "mcontainer::Replace", etc
void Push(pointer Item);

AS @Chris mentioned, there are several libraries for doing this, but there is always an exception to the rule, and you may want to "reinvent the wheel" if you need it.
*I had an application, with its set of libraries, that included some containers / collections. It was made in another progr. langr. and need it to migrate it to C++.
Altought, I also check the c++ standard libraries, I ended migrating my libraries to C++, because I had several libraries calling my container libraries, and need it to do it fast.*
When using "base classes", you may want to "protect" its members, and "take it to the public", in child classes. I usually don't make "private" fields or methods, unless necessarily.
**Summary: Some very common complex stuff (like memory allocation or storage) may be done in your base classes, but, most of those complexity should be leave it to child classes.** |
5,326,525 | I'm writing a container class for fun and education. Previously when writing container classes I had limited myself to just a few very basic methods: `GetValue`, `SetValue`, `GetSize` and `Resize`. I did this to avoid "code spaghetti" so my class would be easier to debug.
However, it occurred to me that users of the class might want to do more than just simple substitution. So I added a few more methods:
```
void Replace(const std::size_t Start, const std::size_t End, const T Value);
void Replace(const std::size_t Start, const std::size_t End, const MyClass Other);
void Insert(const std::size_t Index, const T Value);
void Insert(const std::size_t Index, const MyClass Other);
void Delete(const std::size_t Index);
void Delete(const std::size_t Start, const std::size_t End);
```
In general, should classes provide only the most basic interface and let the users of the class make their own functions to do the complex stuff? Or should the complex stuff be built-in at the cost of maintainability? | 2011/03/16 | [

| Classes should only provide a basic/minimal interface of **member-functions** (and preferably no data!). You can then add convenience methods as **non-friend non-member** functions. According to the interface-principle however, these functions are still part of your classes interface.
You already named the prime reason for this: it makes the class a lot easier to maintain. Also, implementing your "convienence" method part will serve as a nice test to see if you interface is good enough.
Note that the member function part of a container should usually be very generic and powerful, and care not about much more than maintaining class invariants.

Ex:
```
# Root logger option

``` | The message `WARN Please initialize the log4j system properly` means (as stated above) that log4j is not initialized properly because your application can't find the `lo4j.properties` file at runtime.
You can get a basic version of this file here: [log4j sample configuration file (properties file)](https://stackoverflow.com/questions/2128185/log4j-sample-configuration-file-properties-file)
Just put it in your classpath. After we have done this you'll be able to configure the logging level as you want. For example, to turn off all messagges (and keep only actual error messages), in the `lo4j.properties` file you can set the root logger level to error, as explained by *TheEwook*.
If you still have the problem then you should check your **build** procedure, but the specific check depends by the tool you use to compile. For example, if you use Eclipse, usually the `lo4j.properties` should be located in the `resources` directory, which should be set a source folder. If you use Maven, usually such file should be located in the `src/main/resources` directory. If you use Ant, probably you need to copy such file using a Ant's task.
In other words, regardless of your build procedure, make sure that the `lo4j.properties` is made visible in the runtime classpath. |

| You can use the underlying numpy array and [`numpy.choose`](https://numpy.org/doc/stable/reference/generated/numpy.choose.html):
```
s = pd.Series([16,10,17,27])
idx = np.argmin(abs(df.sub(s, axis=0)).values, axis=1)
# array([2, 1, 0, 0])
pd.Series(np.choose(idx, df.values.T), index=s.index)
# 0 17
# 1 12
# 2 19
# 3 22
# dtype: int64
``` | You can get the indices using idxmin and then just read the single values using loc and append them to a list:
```
df = pd.DataFrame({'Col1': {0: 7, 1: 13, 2: 19, 3: 22},
'Col2': {0: 11, 1: 12, 2: 23, 3: 19},
'Col3': {0: 17, 1: 15, 2: 14, 3: 21}})
series = pd.Series([16, 10, 17, 27])
df2 = df.subtract(series, axis=0).abs()
minima = df2.idxmin(axis=1)
result = []
for row, column in minima.iteritems():
result.append(df.loc[row, column])
df_result = pd.DataFrame(result, columns=["minimum"])
```
The last part can also be done using a list comprehension:
```
minima = df2.idxmin(axis=1)
df_result = pd.DataFrame(
[df.loc[row, column] for row, column in minima.iteritems()],
columns=["minimum"]
)

| Nginx is a web server and is concerned with web server stuff, not with how to run Python programs. uWSGI is an application server and knows how to speak WSGI with Python (and other languages now). Both Nginx and uWSGI speak the uWSGI protocol, which is an efficient protocol over UNIX sockets.
Nginx deals with http requests from/responses to the outside world (possibly load balancing, caching, etc.). Your Flask application deals with WSGI requests/responses. uWSGI knows how to start your application (possibly with multiprocessing and/or threading) and bridge the gap between HTTP and WSGI.
There are other HTTP servers besides Nginx, and other WSGI servers besides uWSGI, but they all use the same workflow: the HTTP server passes to the WSGI server, which manages your application process and passes back to the HTTP server.
This setup is known as a [reverse proxy](https://en.wikipedia.org/wiki/Reverse_proxy). It allows each tool to do what it's good at and not be concerned about the other parts of the process. There is nothing particularly inefficient about it, until you get to truly *massive* scales. | Well, WSGI is a specification for interface between Python applications and web servers. uWSGI is (simply put) a realization of this specification written in C/C++. You can run almost any application on a "serious" webserver (like nginx) by just providing an entry point:
```
def application(env, start_response):
start_response('200 OK', [('Content-Type','text/html')])
return ["Hello World"]
```
and then running it like this:
```
uwsgi --http :9090 --wsgi-file file_with_the_code_above.py
```
You can return anything you want instead of ["Hello world"], of course. See <http://uwsgi-docs.readthedocs.org/en/latest/WSGIquickstart.html> for more. |
103,653 | I would appreciate if some trading fundamental analysis expert could please explain me this. Recently I lost basically all my entire life savings, everything i worked for, for over 3 years, waking up daily at 5am. All my money is lost and want to know the solution where and why I was wrong. I am asking for AUDUSD, although similar large consequence was on other symbols too.
So recently Apple's bad results in China effected AUDUSD with large downtrend and I was in uptrend position (because of double bottom pattern) for around two months, praying to go up but it didn't. Obviously Apple is USA company so it should effect symbols (their charts) where USD is either on the left part or on the right part (audUSD) but what I don't understand is the following: there where NEGATIVE news about Apple which means NEGATIVE news about USD too. Since USD is on the ***right*** part of trading symbol, this means that consequence on the chart should be the opposite one comparing to the result of event. This is for sure correct so bad news for Apple means bad news for USD, therefore there should be uptrend but major downtrend occur. My first, out of two, questions is: WHY? How is this possible? AUD, i assume so, cannot be effected on this event (negative news for Apple) but why downtrend if USD is on the right side? It should be uptrend.
Second question: Would you please kindly forward me to some learning resources (links, ebooks,...) or event consultants where could I learn what affect has particular event on what trading symbol? I would like to learn as much as possible about how parameter A (event A) could affect symbol B. Example: I made another very large loss on USDMXN downtrend position when around three months ago some Mexican institution stopped airport construction. I don't know if they stopped continuation of construction or start of construction. Just because in description of event was mentioned name of the country (Mexico) it was easy to understand that this could affect trading symbols that have either on left or right part of the symbol MXN (i lost the money anyway because i know nothing about events but i traded patterns). But if name of the country was missing in event description article, I would have no idea to which symbols is it related to. So in this second question, I am asking where could I learn more about which event has effect on which symbol... I am not economist and going through thousands of economy books would take decades... Please kindly forward me to some resources, consultants, etc.

| The drop in AAPL on Jan 3, 2019, was enough to affect several major US stock indices.
The falling stock market led many investors to move into bonds, increasing US bond prices and reducing US bond yields.
Falling US bond yields tends to drive international investors away from investing in US bonds, leading to a falling US dollar.
On Jan 4, the overall US stock market bounced back considerably, even if AAPL did not. This pulled money back out of bonds, increasing yields. Which brought international traders back to the dollar.
Here you can see how bond prices (represented by the BND ETF) are negatively correlated with the S&P 500 index (^GSPC) and with AUDUSD over the past 5 days:

**Edit**
The event you're asking about isn't in the earlier chart. Here it is in a chart that doesn't skip times when US markets are closed:
[](https://i.stack.imgur.com/JUPDq.png)
Here, I also compared other currencies. It's interesting that JPY and AUD had much bigger reactions than EUR or GBP. Maybe this is related to those countries being in the middle of the trading day when the AAPL announcement was released. Maybe it's totally unrelated to AAPL. At any rate, you should probably re-think your assumption that this was a USD movement and not a AUD (and JPY) movement. | The company suggested that a revenue decline was due to a slowdown in China. A better viewpoint is that the company was simply facing more competition in China and that there was no new news on China.
But the idea of a sharp slowdown in China hit the currency markets very hard. Currency traders with the better viewpoint could have just waited for the currency market to recover.
According to a Forex chart, the January 02 spike-down in the Australian dollar was about 3.6% . A Forex account would have needed about 6.6% margin deposit to keep from having the position closed-out by the spike. Or otherwise, where was the stop-loss set ?
But the Australian dollar does move according to China economic reports because Australia exports to China. Basically to trade currencies the trader must use a source that has a daily calendar of economic reports. A big risk, as is seen here, is an unexpected report. |
37,531,931 | Instructions for installing operating systems inside a VirtualBox virtual machine sometimes advise that the user ensures that the "Live CD/DVD" checkbox is checked. Other instructions don't mention this checkbox at all.

I am able to boot and install live CDs/DVDs regardless of this checkbox's setting, so I'm confused about why it's even there. I could not find a clear reference to this setting in the VirtualBox User Manual either (did I miss it?), leaving me further perplexed.

| Normally, when you eject a CD from the guest OS (e.g. right-click -> eject in File Explorer), it also removes the ISO from the drive (in VM settings page) and it becomes an empty CD drive.
With the "Live CD/DVD" box checked, the ISO is not removed when you eject the disk using the guest OS file explorer and it remains attached to the drive. So for example, if you were to eject the CD before rebooting, you'd still reboot to the Live CD. (without this option, it'd boot to an empty CD drive) | At first I was also unable to find an answer, but the mouseover (in my version) tells me:
