ON WINDOWS 10 After spending 3 frustrating hours of uninstalling & re-installing minikube, virtualbox that did not resolve the problem, I saw the network adapters in my Control Panel->Network and Internet->Network Connections window. There were 3 enabled "VirtualBox Host-Only Ethernet Adapter" ones. I disabled them all. Then on services screen (run->services.msc) find the Tcp/Ip NetBIOS helper and restart it.

A new network adapter with a proper name like "VirtualBox Host-Only Network #3" will be created. Now type: minikube delete mnikube start It worked for me. hope It helped someone! I hate this :)

Just to make sure that in studio version 2.3 you won't see a dropdown near constraint-layout in sdk tools, it will by default install the latest version

To get the desired version check the box saying show package details and boom you can now choose the desired version you want to install

You can use format like here,

  public static double getDoubleValue(String value,int digit){
    if(value==null){
        value="0";
     }
    double i=0;
     try {
         DecimalFormat digitformat = new DecimalFormat("#.##");
         digitformat.setMaximumFractionDigits(digit);
        return Double.valueOf(digitformat.format(Double.parseDouble(value)));

    } catch (NumberFormatException numberFormatExp) {
        return i;   
    }
}

In Git, to "fast forward" means to update the HEAD pointer in such a way that its new value is a direct descendant of the prior value. In other words, the prior value is a parent, or grandparent, or grandgrandparent, ...

Fast forwarding is not possible when the new HEAD is in a diverged state relative to the stream you want to integrate. For instance, you are on master and have local commits, and git fetch has brought new upstream commits into origin/master. The branch now diverges from its upstream and cannot be fast forwarded: your master HEAD commit is not an ancestor of origin/master HEAD. To simply reset master to the value of origin/master would discard your local commits. The situation requires a rebase or merge.

If your local master has no changes, then it can be fast-forwarded: simply updated to point to the same commit as the latestorigin/master. Usually, no special steps are needed to do fast-forwarding; it is done by merge or rebase in the situation when there are no local commits.

Is it ok to assume that fast-forward means all commits are replayed on the target branch and the HEAD is set to the last commit on that branch?

No, that is called rebasing, of which fast-forwarding is a special case when there are no commits to be replayed (and the target branch has new commits, and the history of the target branch has not been rewritten, so that all the commits on the target branch have the current one as their ancestor.)

This should technically be achievable using window.location.reload():

HTML:

<button (click)="refresh()">Refresh</button>

TS:

refresh(): void {
    window.location.reload();
}

Update:

Here is a basic StackBlitz example showing the refresh in action. Notice the URL on "/hello" path is retained when window.location.reload() is executed.

You may want to examine the configuration for your service and make sure that everything is ok. You can navigate to web service via the browser to see if the schema will be rendered on the browser.

You may also want to examine the credentials used to call the service.

from datetime import datetime, timedelta

nine_hours_from_now = datetime.now() + timedelta(hours=9)
#datetime.datetime(2012, 12, 3, 23, 24, 31, 774118)

And then use string formatting to get the relevant pieces:

>>> '{:%H:%M:%S}'.format(nine_hours_from_now)
'23:24:31'

If you're only formatting the datetime then you can use:

>>> format(nine_hours_from_now, '%H:%M:%S')
'23:24:31'

Or, as @eumiro has pointed out in comments - strftime

I have made a query for you. This will give you Recursive Category with a Single Query:

SELECT id,NAME,'' AS subName,'' AS subsubName,'' AS subsubsubName FROM Table1 WHERE prent is NULL
UNION 
SELECT b.id,a.name,b.name AS subName,'' AS subsubName,'' AS subsubsubName FROM Table1 AS a LEFT JOIN Table1 AS b ON b.prent=a.id WHERE a.prent is NULL AND b.name IS NOT NULL 
UNION 
SELECT c.id,a.name,b.name AS subName,c.name AS subsubName,'' AS subsubsubName FROM Table1 AS a LEFT JOIN Table1 AS b ON b.prent=a.id LEFT JOIN Table1 AS c ON c.prent=b.id WHERE a.prent is NULL AND c.name IS NOT NULL 
UNION 
SELECT d.id,a.name,b.name AS subName,c.name AS subsubName,d.name AS subsubsubName FROM Table1 AS a LEFT JOIN Table1 AS b ON b.prent=a.id LEFT JOIN Table1 AS c ON c.prent=b.id LEFT JOIN Table1 AS d ON d.prent=c.id WHERE a.prent is NULL AND d.name IS NOT NULL 
ORDER BY NAME,subName,subsubName,subsubsubName

Here is a fiddle.

It depends on your application. There are some considerations:

• Do you need just the information whether a few numbers are prime, do you need all prime numbers up to a certain limit, or do you need (potentially) all prime numbers?
• How big are the numbers you have to deal with?

The Miller-Rabin and analogue tests are only faster than a sieve for numbers over a certain size (somewhere around a few million, I believe). Below that, using a trial division (if you just have a few numbers) or a sieve is faster.

this is (i think) the most updated answer:

let modelName = UIDevice.current.name

print(modelName)

that's it.

If key isn't an int or float but a string, you need to convert it to an int first by doing

key = int(key)

or to a float by doing

key = float(key)

Otherwise, what you have in your question should work, but

if (key < 1) or (key > 34):

or

if not (1 <= key <= 34):

would be a bit clearer.

Sometimes it happened to me that the method described in the accepted answer didn't work, especially if the separator is a carriage return.
In those cases I solved in this way:

string='first line
second line
third line'

oldIFS="$IFS"
IFS='
'
IFS=${IFS:0:1} # this is useful to format your code with tabs
lines=( $string )
IFS="$oldIFS"

for line in "${lines[@]}"
    do
        echo "--> $line"
done

I used this set up in a react app that works. I created a config file named configstrp.js that contains the following:

module.exports = {
ngrok: {
// use the local frontend port to connect
enabled: process.env.NODE_ENV !== 'production',
port: process.env.PORT || 3000,
subdomain: process.env.NGROK_SUBDOMAIN,
authtoken: process.env.NGROK_AUTHTOKEN
},   }

Require the file in the server.

const configstrp      = require('./config/configstrp.js');
const ngrok = configstrp.ngrok.enabled ? require('ngrok') : null;

and connect as such

if (ngrok) {
console.log('If nGronk')
ngrok.connect(
    {
    addr: configstrp.ngrok.port,
    subdomain: configstrp.ngrok.subdomain,
    authtoken: configstrp.ngrok.authtoken,
    host_header:3000
  },
  (err, url) => {
    if (err) {

    } else {

    }
   }
  );
 }

Do not pass a subdomain if you do not have a custom domain

Call onBackPressed after overriding it in your activity.

If you need a single fadeIn/Out without an explicit user action (like a mouseover/mouseout) you may use a CSS3 animation: http://codepen.io/anon/pen/bdEpwW

.elementToFadeInAndOut {

    animation: fadeinout 4s linear 1 forwards;
}



@keyframes fadeinout {
  0% { opacity: 0; }
  50% { opacity: 1; }
  100% { opacity: 0; }
}

By setting animation-fill-mode: forwards the animation will retain its last keyframe

By setting animation-iteration-count: 1 the animation will run just once (change this value if you need to repeat the effect more than once)

You can use both of ',' OR divide '/' symbols.
But, '/' is better.
Suppose the case of 'every 5 minutes'. If you use ',', you have to write the cron job as following:

0,5,10,15,20,25,30,35,....    *      *     *   * your_command

It means run your_command in every hour in all of defined minutes: 0,5,10,...

However, if you use '/', you can write the following simple and short job:

*/5  *  *  *  *  your_command

It means run your_command in the minutes that are dividable by 5 or in the simpler words, '0,5,10,...'

So, dividable symbol '/' is the best choice always;

You should try to avoid using Singletons, but if you ever do need to, Lazy<T> makes implementing lazy, thread-safe singletons easy:

public sealed class Singleton
{
    // Because Singleton's constructor is private, we must explicitly
    // give the Lazy<Singleton> a delegate for creating the Singleton.
    static readonly Lazy<Singleton> instanceHolder =
        new Lazy<Singleton>(() => new Singleton());

    Singleton()
    {
        // Explicit private constructor to prevent default public constructor.
        ...
    }

    public static Singleton Instance => instanceHolder.Value;
}

Should work.

Here's a working example:

http://jsfiddle.net/rhpNc/

Excerpt:

function loadIframe(iframeName, url) {
    var $iframe = $('#' + iframeName);
    if ($iframe.length) {
        $iframe.attr('src',url);
        return false;
    }
    return true;
}

While the built-in libs for XML parsing are quite good I am partial to lxml.

But for parsing RSS feeds, I'd recommend Universal Feed Parser, which can also parse Atom. Its main advantage is that it can digest even most malformed feeds.

Python 2.6 already includes a JSON parser, but a newer version with improved speed is available as simplejson.

With these tools building your app shouldn't be that difficult.

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

Both John Conde's and ryeballar's answers are correct and will work.

If you want to get too geeky:

• John's has the downside that it has to make two decisions per $digest loop (it has to decide whether to add/remove center and it has to decide whether to add/remove left), when clearly only one is needed.

• Ryeballar's relies on the ternary operator which is probably going to be removed at some point (because the view should not contain any logic). (We can't be sure it will indeed be removed and it probably won't be any time soon, but if there is a more "safe" solution, why not ?)

So, you can do the following as an alternative:

ng-class="{true:'center',false:'left'}[page.isSelected(1)]"

** Update**: 11/19/2019

Microsoft has released a new version of the control 150.1400.0 in their Nuget library. My short testing shows that it works again in the forms designer where 150.1357.0 and 150.1358.0 did not. This includes being able to resize and modify the ReportViewer Tasks on the control itself.

** Update**: 8/18/2019

Removing the latest version and rolling back to 150.900.148.0 seems to work on multiple computers I'm using with VS2017 and VS2019.

You can roll back to 150.900.148 in the Nuget solution package manager. It works similarly to the previous versions. Use the drop down box to select the older version.

It may be easier to manually delete references to post 150.900 versions of ReportViewer and readd them than it is to fix them.

Remember to restart Visual Studio after changing the toolbox entry.

Update: 8/7/2019

A newer version of the ReportViewer control has been released, probably coinciding with Visual Studio 2019. I was working with V150.1358.0.

Following the directions in this answer gets the control in the designer's toolbox. But once dropped on the form it doesn't display. The control shows up below the form as a non-visual component.

This is working as designed according to Microsoft SQL BI support. This is the group responsible for the control.

While you still cannot interact with the control directly, these additional steps give a workaround so the control can be sized on the form. While now visible, the designer treats the control as if it didn't exist.

I've created a feedback request at the suggestion of Microsoft SQL BI support. Please consider voting on it to get Microsoft's attention.

Microsoft Azure Feedback page - Restore Designtime features of the WinForms ReportViewer Control

Additional steps:

• After adding the reportviewer to the WinForm
• Add a Panel Control to the WinForm.

• In the form's form.designer.cs file, add the Reportviewer control to the panel.

    // 
    // panel1
    // 
    this.panel1.Controls.Add(this.reportViewer1);
  

• Return to the form's designer, you should see the reportViewer on the panel

• In the Properties panel select the ReportViewer in the controls list dropdown
• Set the reportViewer's Dock property to Fill

Now you can position the reportViewer by actually interacting with the panel.

Update: Microsoft released a document on April 18, 2017 describing how to configure and use the reporting tool in Visual Studio 2017.

Visual Studio 2017 does not have the ReportViewer tool installed by default in the ToolBox. Installing the extension Microsoft Rdlc Report Designer for Visual Studio and then adding that to the ToolBox results in a non-visual component that appears below the form.

Microsoft Support had told me this is a bug, but as of April 21, 2017 it is "working as designed".

The following steps need to be followed for each project that requires ReportViewer.

• If you have ReportViewer in the Toolbox, remove it. Highlight, right-click and delete.
  • You will have to have a project with a form open to do this.

Edited 8/7/2019 - It looks like the current version of the RDLC Report Designer extension no longer interferes. You need this to actually edit the reports.

• If you have the Microsoft Rdlc Report Designer for Visual Studio extension installed, uninstall it.

• Close your solution and restart Visual Studio. This is a crucial step, errors will occur if VS is not restarted when switching between solutions.

• Open your solution.
• Open the NuGet Package Manager Console (Tools/NuGet Package Manager/Package Manager Console)

• At the PM> prompt enter this command, case matters.

  Install-Package Microsoft.ReportingServices.ReportViewerControl.WinForms

  You should see text describing the installation of the package.

Now we can temporarily add the ReportViewer tool to the tool box.

• Right-click in the toolbox and use Choose Items...

• We need to browse to the proper DLL that is located in the solutions Packages folder, so hit the browse button.

• In our example we can paste in the packages folder as shown in the text of Package Manager Console.

  C:\Users\jdoe\Documents\Projects\_Test\ReportViewerTest\WindowsFormsApp1\packages

• Then double click on the folder named Microsoft.ReportingServices.ReportViewerControl.Winforms.140.340.80

  The version number will probably change in the future.

• Then double-click on lib and again on net40.

• Finally, double click on the file Microsoft.ReportViewer.WinForms.dll

  You should see ReportViewer checked in the dialog. Scroll to the right and you will see the version 14.0.0.0 associated to it.

• Click OK.

ReportViewer is now located in the ToolBox.

• Drag the tool to the desired form(s).

• Once completed, delete the ReportViewer tool from the tool box. You can't use it with another project.

• You may save the project and are good to go.

Remember to restart Visual Studio any time you need to open a project with ReportViewer so that the DLL is loaded from the correct location. If you try and open a solution with a form with ReportViewer without restarting you will see errors indicating that the “The variable 'reportViewer1' is either undeclared or was never assigned.“.

If you add a new project to the same solution you need to create the project, save the solution, restart Visual Studio and then you should be able to add the ReportViewer to the form. I have seen it not work the first time and show up as a non-visual component.

When that happens, removing the component from the form, deleting the Microsoft.ReportViewer.* references from the project, saving and restarting usually works.

You can solve this problem by following few steps:

1) open your terminal window

2) please write following command in your terminal

ssh root@yourIP port

3) Enter root password

4) Now edit your server my.cnf file using below command

nano /etc/my.cnf  

if command is not recognized do this first or try vi then repeat: yum install nano.

OR

  vi /etc/my.cnf 

5) Add the line under the [MYSQLD] section. :

max_allowed_packet=524288000 (obviously adjust size for whatever you need) 
wait_timeout = 100

6) Control + O (save) then ENTER (confirm) then Control + X (exit file)

7) Then restart your mysql server by following command

/etc/init.d/mysql stop
/etc/init.d/mysql start

8) You can verify by going into PHPMyAdmin or opening a SQL command window and executing:

SHOW VARIABLES LIKE 'max_allowed_packet'

This works for me. I hope it should work for you.

The main point of the differences as pointed out @BizApps is that Load event happens right after the ViewState is populated while PreRender event happens later, right before Rendering phase, and after all individual children controls' action event handlers are already executing. Therefore, any modifications done by the controls' actions event handler should be updated in the control hierarchy during PreRender as it happens after.

I imagine this forum posting, which I quote fully below, should answer the question.

Inside a procedure, function, or trigger definition, or in a dynamic SQL statement (embedded in a host program):

BEGIN ATOMIC
 DECLARE example VARCHAR(15) ;
 SET example = 'welcome' ;
 SELECT *
 FROM   tablename
 WHERE  column1 = example ;
END

or (in any environment):

WITH t(example) AS (VALUES('welcome'))
SELECT *
FROM   tablename, t
WHERE  column1 = example

or (although this is probably not what you want, since the variable needs to be created just once, but can be used thereafter by everybody although its content will be private on a per-user basis):

CREATE VARIABLE example VARCHAR(15) ;
SET example = 'welcome' ;
SELECT *
FROM   tablename
WHERE  column1 = example ;

Now in 2020 Selenium 4 supports authenticating using Basic and Digest auth . Its using the CDP and currently only supports chromium-derived browsers

Example :

Java Example :

    Webdriver driver = new ChromeDriver();
    
    ((HasAuthentication) driver).register(UsernameAndPassword.of("username", "pass"));

    driver.get("http://sitewithauth");
    
 

Note : In Alpha-7 there is bug where it send username for both user/password. Need to wait for next release of selenium version as fix is available in trunk https://github.com/SeleniumHQ/selenium/commit/4917444886ba16a033a81a2a9676c9267c472894

There are 3 basic commands to compare files in unix:

1. cmp : This command is used to compare two files byte by byte and as any mismatch occurs,it echoes it on the screen.if no mismatch occurs i gives no response. syntax:$cmp file1 file2.

2. comm : This command is used to find out the records available in one but not in another

3. diff

Here's another method (ES6 w/std Promise). Uses lodash/underscore type exit criteria (return === false). Note that you could easily add an exitIf() method in options to run in doOne().

const whilePromise = (fnReturningPromise,options = {}) => { 
    // loop until fnReturningPromise() === false
    // options.delay - setTimeout ms (set to 0 for 1 tick to make non-blocking)
    return new Promise((resolve,reject) => {
        const doOne = () => {
            fnReturningPromise()
            .then((...args) => {
                if (args.length && args[0] === false) {
                    resolve(...args);
                } else {
                    iterate();
                }
            })
        };
        const iterate = () => {
            if (options.delay !== undefined) {
                setTimeout(doOne,options.delay);
            } else {
                doOne();
            }
        }
        Promise.resolve()
        .then(iterate)
        .catch(reject)
    })
};

I assume that you are using MasterPage so within your master page you should have

<head runat="server">
    <asp:ContentPlaceHolder ID="head" runat="server">
    </asp:ContentPlaceHolder>
</head>

And within any of your pages based on that MasterPage add this

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
    <script src="js/yourscript.js" type="text/javascript"></script>
</asp:Content>

Short and precise answer which answers all your questions formally from JLS:

3.10.7. The Null Literal

The null type has one value, the null reference, represented by the null literal null, which is formed from ASCII characters.

A null literal is always of the null type.

Only a reference of type which is assigned to null is allocated. You don't assign any value (object) to the reference. Such allocation is specific to JVM how much reference will take and in which memory area it will be allocated.

The second of the two methods here does what you're wanting. I've just used it (after finding no success in this thread) and it's worked for me.

You have two options:

1. Configure Workspace Settings (disable the validation for the current workspace): Go to Window > Preferences > Validation and uncheck the manual and build for: XML Schema Validator, XML Validator

2. Check enable project specific settings (disable the validation for this project): Right-click on the project, select Properties > Validation and uncheck the manual and build for: XML Schema Validator, XML Validator

Right-click on the project and select Validate to make the errors disappear.

If only one checkbox should be checked in the same time use RadioButtonFor instead:

      @Html.RadioButtonFor(model => model.Type,1, new { @checked = "checked" }) fultime
      @Html.RadioButtonFor(model => model.Type,2) party
      @Html.RadioButtonFor(model => model.Type,3) next option...

If one more one could be checked in the same time use excellent extension: CheckBoxListFor:

Hope,it will help

It's possible, use the structure below:

<li><a><span></span></a></li>
<li><a><span></span></a></li>

etc...

Where the <li> contains an <a> anchor tag that contains a span as shown above. Then insert the following css:

• LI get position: relative;
• Give <a> tag a height, width
• Set <span> width & height to 100%, so that both <a> and <span> have same dimensions
• Both <a> and <span> get position: relative;.
• Assign the same background image to each element
• <a> tag will have the 'OFF' background-position, and the <span> will have the 'ON' background-poisiton.
• For 'OFF' state use opacity 0 for <span>
• For 'ON' :hover state use opacity 1 for <span>
• Set the -webkit or -moz transition on the <span> element

You'll have the ability to use the transition effect while still defaulting to the old background-position swap. Don't forget to insert IE alpha filter.

Tomcat 7 Context hold Loader element. According to docs deployment descriptor (what in <Context> tag) can be placed in:

• $CATALINA_BASE/conf/[enginename]/[hostname]/$APP.xml - best - completely out of application and automatically scanned for changes!!!

Here my config which demonstrate how to use development version of project files out of $CATALINA_BASE hierarchy (note that I place this file into src/test/resources dir and intruct Maven to preprocess ${basedir} placeholders through pom.xml <filtering>true</filtering> so after build in new environment I copy it to $CATALINA_BASE/conf/Catalina/localhost/$APP.xml):

You don't seem to have the stopwords corpus on your computer.

You need to start the NLTK Downloader and download all the data you need.

Open a Python console and do the following:

>>> import nltk
>>> nltk.download()
showing info http://nltk.github.com/nltk_data/

In the GUI window that opens simply press the 'Download' button to download all corpora or go to the 'Corpora' tab and only download the ones you need/want.

one way: List.AddRange() depending on the types?

Ran into this issue today (Excel crashes on adding rows using .ListRows.Add). After reading this post and checking my table, I realized the calculations of the formula's in some of the cells in the row depend on a value in other cells. In my case of cells in a higher column AND even cells with a formula!

The solution was to fill the new added row from back to front, so calculations would not go wrong.

Excel normally can deal with formula's in different cells, but it seems adding a row in a table kicks of a recalculation in order of the columns (A,B,C,etc..).

Hope this helps clearing issues with .ListRows.Add

First way is

function function1()
{
  var variable1=12;
  function2(variable1);
}

function function2(val)
{
  var variableOfFunction1 = val;

// Then you will have to use this function for the variable1 so it doesn't really help much unless that's what you want to do. }

Second way is

var globalVariable;
function function1()
{
  globalVariable=12;
  function2();
}

function function2()
{
  var local = globalVariable;
}

Try this for a unique list.

ping -c 5 -b 10.10.0.255 | grep 'bytes from' | awk '{ print $4 }' | sort | uniq

another method (fetches live hosts):

fping -ag 192.168.1.0/24

Your usage is correct. I bet that your external program, flow.exe, needs to be executed in its directory, because it accesses some external files stored there.

So you might try:

import sys, string, os, arcgisscripting
os.chdir('c:\\documents and settings\\flow_model')
os.system('"C:\\Documents and Settings\\flow_model\\flow.exe"')

(Beware of the double quotes inside the single quotes...)

Just set the height and width where you are adding that logo. I tried and its working fine

Line numbers were added to the IDLE editor two days ago and will appear in the upcoming 3.8.0a3 and later 3.7.5. For new windows, they are off by default, but this can be reversed on the Setting dialog, General tab, Editor section. For existing windows, there is a new Show (Hide) Line Numbers entry on the Options menu. There is currently no hotkey. One can select a line or bloc of lines by clicking on a line or clicking and dragging.

Some people may have missed Edit / Go to Line. The right-click context menu Goto File/Line works on grep (Find in Files) output as well as on trackbacks.

The solution mentioned in ".gitignore file not ignoring" is a bit extreme, but should work:

# rm all files
git rm -r --cached .
# add all files as per new .gitignore
git add .
# now, commit for new .gitignore to apply
git commit -m ".gitignore is now working"

(make sure to commit first your changes you want to keep, to avoid any incident as jball037 comments below.
The --cached option will keep your files untouched on your disk though.)

You also have other more fine-grained solution in the blog post "Making Git ignore already-tracked files":

git rm --cached `git ls-files -i --exclude-standard`

Bassim suggests in his edit:

Files with space in their paths

In case you get an error message like fatal: path spec '...' did not match any files, there might be files with spaces in their path.

You can remove all other files with option --ignore-unmatch:

git rm --cached --ignore-unmatch `git ls-files -i --exclude-standard`

but unmatched files will remain in your repository and will have to be removed explicitly by enclosing their path with double quotes:

git rm --cached "<path.to.remaining.file>"

Download ilmerge and ilmergre gui . makes joining the files so easy ive used these and works great

I'm quite late to the party, but one approach is to use a static inner class to unwrap values:

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

class Scratch {
    private final String aString;
    private final String bString;
    private final String cString;
    private final static String jsonString;

    static {
        jsonString = "{\n" +
                "  \"wrap\" : {\n" +
                "    \"A\": \"foo\",\n" +
                "    \"B\": \"bar\",\n" +
                "    \"C\": \"baz\"\n" +
                "  }\n" +
                "}";
    }

    @JsonCreator
    Scratch(@JsonProperty("A") String aString,
            @JsonProperty("B") String bString,
            @JsonProperty("C") String cString) {
        this.aString = aString;
        this.bString = bString;
        this.cString = cString;
    }

    @Override
    public String toString() {
        return "Scratch{" +
                "aString='" + aString + '\'' +
                ", bString='" + bString + '\'' +
                ", cString='" + cString + '\'' +
                '}';
    }

    public static class JsonDeserializer {
        private final Scratch scratch;

        @JsonCreator
        public JsonDeserializer(@JsonProperty("wrap") Scratch scratch) {
            this.scratch = scratch;
        }

        public Scratch getScratch() {
            return scratch;
        }
    }

    public static void main(String[] args) throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();
        Scratch scratch = objectMapper.readValue(jsonString, Scratch.JsonDeserializer.class).getScratch();
        System.out.println(scratch.toString());
    }
}

However, it's probably easier to use objectMapper.configure(SerializationConfig.Feature.UNWRAP_ROOT_VALUE, true); in conjunction with @JsonRootName("aName"), as pointed out by pb2q

No, if you are debugging an app without other users use the Build > Build APK(s) menu in Android Studio or execute it in your device/emulator them the debug release apk will install automatically. If you are debugging an app with others use Build > Generate Signed APK... menu. If you want to publish the beta version use the Google Play Store. Your APK(s) will be in app\build\outputs\apk\debug and app\release folders.

If you have access to on the server, consider setting headers as answered in this more general question.

Content-Type: application/octet-stream
Content-Disposition: attachment;filename=\"filename.xxx\"

Reading the comments on that answer, it is advisable to use a more specific Content-Type than octet-stream.

Based on the link provided by @better_use_mkstemp, here's a fiddle where nested iframe resizes to fill parent div: http://jsfiddle.net/orlenko/HNyJS/

I thought I will share how I resolved the same issue "Error Could not open lib\amd64\jvm.cfg". I found the Java run time Jre7 is missing amd64 folder under lib. However, I have 1.7.0_25 JDK which is having jre folder and also having amd64.

I moved the original contents of jre7 folder to a backup file and copied everything from 1.7.0_25\jre.

Now I am not getting this error anymore and able to proceed with scene builder.

I've done like this:

    Uri queryUri = MediaStore.Files.getContentUri("external");
    String columnData = MediaStore.Files.FileColumns.DATA;
    String columnSize = MediaStore.Files.FileColumns.SIZE;

    String[] projectionData = {MediaStore.Files.FileColumns.DATA};


    String name = null;
    String size = null;

    Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
    if ((cursor != null)&&(cursor.getCount()>0)) {
        int nameIndex = cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
        int sizeIndex = cursor.getColumnIndex(OpenableColumns.SIZE);

        cursor.moveToFirst();

        name = cursor.getString(nameIndex);
        size = cursor.getString(sizeIndex);

        cursor.close();
    }

    if ((name!=null)&&(size!=null)){
        String selectionNS = columnData + " LIKE '%" + name + "' AND " +columnSize + "='" + size +"'";

        Cursor cursorLike = getContentResolver().query(queryUri, projectionData, selectionNS, null, null);

        if ((cursorLike != null)&&(cursorLike.getCount()>0)) {
            cursorLike.moveToFirst();
            int indexData = cursorLike.getColumnIndex(columnData);
            if (cursorLike.getString(indexData) != null) {
                result = cursorLike.getString(indexData);
            }
            cursorLike.close();
        }
    }

    return result;

You don't need the into statements:

var query = 
    from customer in dc.Customers
    from order in dc.Orders
         .Where(o => customer.CustomerId == o.CustomerId)
         .DefaultIfEmpty()
    select new { Customer = customer, Order = order } 
    //Order will be null if the left join is null

And yes, the query above does indeed create a LEFT OUTER join.

Link to a similar question that handles multiple left joins: Linq to Sql: Multiple left outer joins

I use both Clang and GCC, I find Clang has some useful warnings, but for my own ray-tracing benchmarks - its consistently 5-15% slower then GCC (take that with grain of salt of course, but attempted to use similar optimization flags for both).

So for now I use Clang static analysis and its warnings with complex macros: (though now GCC's warnings are pretty much as good - gcc4.8 - 4.9).

Some considerations:

• Clang has no OpenMP support, only matters if you take advantage of that but since I do, its a limitation for me. (*****)
• Cross compilation may not be as well supported (FreeBSD 10 for example still use GCC4.x for ARM), gcc-mingw for example is available on Linux... (YMMV).
• Some IDE's don't yet support parsing Clangs output (QtCreator for example *****). EDIT: QtCreator now supports Clang's output
• Some aspects of GCC are better documented and since GCC has been around for longer and is widely used, you might find it easier to get help with warnings / error messages.

***** - these areas are in active development and may soon be supported

If you are facing this problem it could be that the environment variable(s) is added/loaded after the file that requires the specific variable

const express = require('express');

const app = express();
const mongoose = require('mongoose');
const dotenv = require('dotenv');
const morgan = require('morgan');

const passport = require('passport'); //you want to use process.env.JWT_SECRET (you will get undefined)

dotenv.config();

in the above case, you will get undefined for the process.env.JWT_SECRET

So the solution is that you put dotenv.config() before const passport = require('passport');

const express = require('express');

const app = express();
const mongoose = require('mongoose');
const dotenv = require('dotenv');
const morgan = require('morgan');
dotenv.config();   
const passport = require('passport'); //you want to use process.env.JWT_SECRET (you will get the value for the enviroment variable)

git log -n 1 [branch_name]

branch_name (may be remote or local branch) is optional. Without branch_name, it will show the latest commit on the current branch.

For example:

git log -n 1
git log -n 1 origin/master
git log -n 1 some_local_branch

git log -n 1 --pretty=format:"%H"  #To get only hash value of commit

I found myself here after needing this same query for some Business Intelligence Queries I'm running on an e-commerce store. I wanted to add my solution as it may be helpful to others.

set @firstOfLastLastMonth = DATE_SUB(LAST_DAY(DATE_ADD(NOW(), INTERVAL -2 MONTH)),INTERVAL DAY(LAST_DAY(DATE_ADD(NOW(), INTERVAL -2 MONTH)))-1 DAY);
set @lastOfLastLastMonth = LAST_DAY(DATE_ADD(NOW(), INTERVAL -2 MONTH));
set @firstOfLastMonth = DATE_SUB(LAST_DAY(DATE_ADD(NOW(), INTERVAL -1 MONTH)),INTERVAL DAY(LAST_DAY(DATE_ADD(NOW(), INTERVAL -1 MONTH)))-1 DAY);
set @lastOfLastMonth = LAST_DAY(DATE_ADD(NOW(), INTERVAL -1 MONTH));
set @firstOfMonth = DATE_ADD(@lastOfLastMonth, INTERVAL 1 DAY);
set @today = CURRENT_DATE;

Today is 2019-10-08 so the output looks like

@firstOfLastLastMonth = '2019-08-01'
@lastOfLastLastMonth = '2019-08-31'
@firstOfLastMonth = '2019-09-01'
@lastOfLastMonth = '2019-09-30'
@firstOfMonth = '2019-10-01'
@today = '2019-10-08'

What matters isn't the attribute but the property, and its value is a boolean.

You can set it using

 document.getElementById("edName").required = true;

For doing a PUT in HTML correctly, you will have to surround it with try/catch:

try {
    url = new URL("http://www.example.com/resource");
    HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
    httpCon.setDoOutput(true);
    httpCon.setRequestMethod("PUT");
    OutputStreamWriter out = new OutputStreamWriter(
        httpCon.getOutputStream());
    out.write("Resource content");
    out.close();
    httpCon.getInputStream();
} catch (MalformedURLException e) {
    e.printStackTrace();
} catch (ProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

For me this was to do with a constraint that I was removing at build time. Unticking Remove at build time fixed the issue, and I suspect the compiler had an issue determining the layout without it.

The error code will mention which Storyboard is causing the issue.

The guy above gave comparison for HashMap / HashSet vs. TreeMap / TreeSet.

I will talk about ArrayList vs. LinkedList:

ArrayList:

• O(1) get()
• amortized O(1) add()
• if you insert or delete an element in the middle using ListIterator.add() or Iterator.remove(), it will be O(n) to shift all the following elements

LinkedList:

• O(n) get()
• O(1) add()
• if you insert or delete an element in the middle using ListIterator.add() or Iterator.remove(), it will be O(1)

Thomas Becker wrote a useful article on the subject here.

There was also this (perhaps simpler) approach that appeared previously on SO: How to correctly implement custom iterators and const_iterators?

I know this is a really old thread, but it shows up at the top in Google, so here's another option.

This one is pure CSS, and doesn't require any extra HTML.

box-shadow: inset 0 0 0 1000px rgba(0,0,0,.2);

There are a surprising number of uses for the box-shadow feature.

I'm not sure that you're creating a set with this ([1, 2]) syntax, rather a list. To create a set, you should use set([1, 2]).

These brackets are just envelopping your expression, as if you would have written:

if (condition1
    and condition2 == 3):
    print something

There're not really ignored, but do nothing to your expression.

Note: (something, something_else) will create a tuple (but still no list).

One the elements are added, use the rules method to add the rules

//bug fixed thanks to @Sparky
$('input[name^="fileupload"]').each(function () {
    $(this).rules('add', {
        required: true,
        accept: "image/jpeg, image/pjpeg"
    })
})

Demo: Fiddle

Update

var filenumber = 1;
$("#AddFile").click(function () { //User clicks button #AddFile
    var $li = $('<li><input type="file" name="FileUpload' + filenumber + '" id="FileUpload' + filenumber + '" required=""/> <a href="#" class="RemoveFileUpload">Remove</a></li>').prependTo("#FileUploader");

    $('#FileUpload' + filenumber).rules('add', {
        required: true,
        accept: "image/jpeg, image/pjpeg"
    })

    filenumber++;
    return false;
});

It is actually possible to do it using .NET regular expressions, but it is not trivial, so read carefully.

You can read a nice article here. You also may need to read up on .NET regular expressions. You can start reading here.

Angle brackets <> were used because they do not require escaping.

The regular expression looks like this:

<
[^<>]*
(
    (
        (?<Open><)
        [^<>]*
    )+
    (
        (?<Close-Open>>)
        [^<>]*
    )+
)*
(?(Open)(?!))
>

You can use a dict comprehension for this pretty easily:

a = ['hello','world','1','2']

my_dict = {item : a[index+1] for index, item in enumerate(a) if index % 2 == 0}

This is equivalent to the for loop below:

my_dict = {}
for index, item in enumerate(a):
    if index % 2 == 0:
        my_dict[item] = a[index+1]

cmd.Parameters.Add(String parameterName, Object value) is deprecated now. Instead use cmd.Parameters.AddWithValue(String parameterName, Object value)

Add(String parameterName, Object value) has been deprecated. Use AddWithValue(String parameterName, Object value)

There is no difference in terms of functionality. The reason they deprecated the cmd.Parameters.Add(String parameterName, Object value) in favor of AddWithValue(String parameterName, Object value) is to give more clarity. Here is the MSDN reference for the same

private void button1_Click(object sender, EventArgs e) {
  using (SqlConnection con = new SqlConnection(dc.Con)) {
    using (SqlCommand cmd = new SqlCommand("sp_Add_contact", con)) {
      cmd.CommandType = CommandType.StoredProcedure;

      cmd.Parameters.AddWithValue("@FirstName", SqlDbType.VarChar).Value = txtFirstName.Text;
      cmd.Parameters.AddWithValue("@LastName", SqlDbType.VarChar).Value = txtLastName.Text;

      con.Open();
      cmd.ExecuteNonQuery();
    }
  }
}

You can also use CopyTo:

var ms = new MemoryStream();
yourStreamReader.BaseStream.CopyTo(ms); // blocking call till the end of the stream
ms.GetBuffer().CopyTo(yourArray, ms.Length);

or

var ms = new MemoryStream();
var ct = yourStreamReader.BaseStream.CopyToAsync(ms);
await ct;
ms.GetBuffer().CopyTo(yourArray, ms.Length);

Stumbled onto this, was strangely hard to find again later. Putting here for posterity:

sudo yum install nodejs npm --enablerepo=epel

EDIT 3: As of July 2016, EDIT 1 no longer works for nodejs 4 (and EDIT 2 neither). This answer (https://stackoverflow.com/a/35165401/78935) gives a true one-liner.

EDIT 1: If you're looking for nodejs 4, please try the EPEL testing repo:

sudo yum install nodejs --enablerepo=epel-testing

EDIT 2: To upgrade from nodejs 0.12 installed through the EPEL repo using the command above, to nodejs 4 from the EPEL testing repo, please follow these steps:

sudo yum rm nodejs
sudo rm -f /usr/local/bin/node
sudo yum install nodejs --enablerepo=epel-testing

The newer packages put the node binaries in /usr/bin, instead of /usr/local/bin.

And some background:

The option --enablerepo=epel causes yum to search for the packages in the EPEL repository.

EPEL (Extra Packages for Enterprise Linux) is open source and free community based repository project from Fedora team which provides 100% high quality add-on software packages for Linux distribution including RHEL (Red Hat Enterprise Linux), CentOS, and Scientific Linux. Epel project is not a part of RHEL/Cent OS but it is designed for major Linux distributions by providing lots of open source packages like networking, sys admin, programming, monitoring and so on. Most of the epel packages are maintained by Fedora repo.

Defining a NAME containing the lookup is a neat solution, HOWEVER, it always seems to store the sheet name with the cell reference. However, I think if you delete the sheet name in the '' quotes but leave the "!", it may work.

Maybe these two examples illustrate you the difference between a deadlock and a livelock:

Java-Example for a deadlock:

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class DeadlockSample {

    private static final Lock lock1 = new ReentrantLock(true);
    private static final Lock lock2 = new ReentrantLock(true);

    public static void main(String[] args) {
        Thread threadA = new Thread(DeadlockSample::doA,"Thread A");
        Thread threadB = new Thread(DeadlockSample::doB,"Thread B");
        threadA.start();
        threadB.start();
    }

    public static void doA() {
        System.out.println(Thread.currentThread().getName() + " : waits for lock 1");
        lock1.lock();
        System.out.println(Thread.currentThread().getName() + " : holds lock 1");

        try {
            System.out.println(Thread.currentThread().getName() + " : waits for lock 2");
            lock2.lock();
            System.out.println(Thread.currentThread().getName() + " : holds lock 2");

            try {
                System.out.println(Thread.currentThread().getName() + " : critical section of doA()");
            } finally {
                lock2.unlock();
                System.out.println(Thread.currentThread().getName() + " : does not hold lock 2 any longer");
            }
        } finally {
            lock1.unlock();
            System.out.println(Thread.currentThread().getName() + " : does not hold lock 1 any longer");
        }
    }

    public static void doB() {
        System.out.println(Thread.currentThread().getName() + " : waits for lock 2");
        lock2.lock();
        System.out.println(Thread.currentThread().getName() + " : holds lock 2");

        try {
            System.out.println(Thread.currentThread().getName() + " : waits for lock 1");
            lock1.lock();
            System.out.println(Thread.currentThread().getName() + " : holds lock 1");

            try {
                System.out.println(Thread.currentThread().getName() + " : critical section of doB()");
            } finally {
                lock1.unlock();
                System.out.println(Thread.currentThread().getName() + " : does not hold lock 1 any longer");
            }
        } finally {
            lock2.unlock();
            System.out.println(Thread.currentThread().getName() + " : does not hold lock 2 any longer");
        }
    }
}

Sample output:

Thread A : waits for lock 1
Thread B : waits for lock 2
Thread A : holds lock 1
Thread B : holds lock 2
Thread B : waits for lock 1
Thread A : waits for lock 2

Java-Example for a livelock:

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class LivelockSample {

    private static final Lock lock1 = new ReentrantLock(true);
    private static final Lock lock2 = new ReentrantLock(true);

    public static void main(String[] args) {
        Thread threadA = new Thread(LivelockSample::doA, "Thread A");
        Thread threadB = new Thread(LivelockSample::doB, "Thread B");
        threadA.start();
        threadB.start();
    }

    public static void doA() {
        try {
            while (!lock1.tryLock()) {
                System.out.println(Thread.currentThread().getName() + " : waits for lock 1");
                Thread.sleep(100);
            }
            System.out.println(Thread.currentThread().getName() + " : holds lock 1");

            try {
                while (!lock2.tryLock()) {
                    System.out.println(Thread.currentThread().getName() + " : waits for lock 2");
                    Thread.sleep(100);
                }
                System.out.println(Thread.currentThread().getName() + " : holds lock 2");

                try {
                    System.out.println(Thread.currentThread().getName() + " : critical section of doA()");

Sample output:

Thread B : holds lock 2
Thread A : holds lock 1
Thread A : waits for lock 2
Thread B : waits for lock 1
Thread B : waits for lock 1
Thread A : waits for lock 2
Thread A : waits for lock 2
Thread B : waits for lock 1
Thread B : waits for lock 1
Thread A : waits for lock 2
Thread A : waits for lock 2
Thread B : waits for lock 1
...

Both examples force the threads to aquire the locks in different orders. While the deadlock waits for the other lock, the livelock does not really wait - it desperately tries to acquire the lock without the chance of getting it. Every try consumes CPU cycles.

This thread provides the code necessary: http://bytes.com/forum/thread251367.html

but here's the relevant code:

using System.Runtime.InteropServices;

[StructLayout(LayoutKind.Sequential, Pack=1)]
internal struct TokPriv1Luid
{
    public int Count;
    public long Luid;
    public int Attr;
}

private void DoExitWin( int flg )
{
    bool ok;
    TokPriv1Luid tp;
    IntPtr hproc = GetCurrentProcess();
    IntPtr htok = IntPtr.Zero;
    ok = OpenProcessToken( hproc, TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, ref htok );
    tp.Count = 1;
    tp.Luid = 0;
    tp.Attr = SE_PRIVILEGE_ENABLED;
    ok = LookupPrivilegeValue( null, SE_SHUTDOWN_NAME, ref tp.Luid );
    ok = AdjustTokenPrivileges( htok, false, ref tp, 0, IntPtr.Zero, IntPtr.Zero );
    ok = ExitWindowsEx( flg, 0 );
    }

Usage:

DoExitWin( EWX_SHUTDOWN );

or

DoExitWin( EWX_REBOOT );

you can save the original queue to a temporary queue. Then you simply do your normal pop on the temporary queue to go through the original one, for example:

queue tmp_q = original_q; //copy the original queue to the temporary queue

while (!tmp_q.empty())
{
    q_element = tmp_q.front();
    std::cout << q_element <<"\n";
    tmp_q.pop();
} 

At the end, the tmp_q will be empty but the original queue is untouched.

The syntax "select top (@var) ..." only works in SQL SERVER 2005+. For SQL 2000, you can do:

set rowcount @top

select * from sometable

set rowcount 0 

Hope this helps

Oisin.

(edited to replace @@rowcount with rowcount - thanks augustlights)

Use the wildcard "#" but beware that at some point you will have to somehow understand the data passing through the bus!

If you need an instance of HashMap, the best way is:

fileParameters = new HashMap<String,String>();

Since Map is an interface, you need to pick some class that instantiates it if you want to create an empty instance. HashMap seems as good as any other - so just use that.

Have you looked at the samples provided with EPPlus?

This one shows you how to create a file http://epplus.codeplex.com/wikipage?title=ContentSheetExample

This one shows you how to use it to stream back a file http://epplus.codeplex.com/wikipage?title=WebapplicationExample

This is how we use the package to generate a file.

var newFile = new FileInfo(ExportFileName);
using (ExcelPackage xlPackage = new ExcelPackage(newFile))
{                       
    // do work here                            
    xlPackage.Save();
}

UTF-8 is not a character set, it's an encoding. The character set for UTF-8 is Unicode. If you want to store Unicode text you use the nvarchar data type.

If the database would use UTF-8 to store text, you would still not get the text out as encoded UTF-8 data, you would get it out as decoded text.

You can easily store UTF-8 encoded text in the database, but then you don't store it as text, you store it as binary data (varbinary).

Configuration

You can enable GZIP compression entirely in your Web.config file. This is particularly useful if you're on shared hosting and can't configure IIS directly, or you want your config to carry between all environments you target.

<system.webServer>
  <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
    <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
    <dynamicTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </dynamicTypes>
    <staticTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </staticTypes>
  </httpCompression>
  <urlCompression doStaticCompression="true" doDynamicCompression="true"/>
</system.webServer>

Testing

To test whether compression is working or not, use the developer tools in Chrome or Firebug for Firefox and ensure the HTTP response header is set:

Content-Encoding: gzip

Note that this header won't be present if the response code is 304 (Not Modified). If that's the case, do a full refresh (hold shift or control while you press the refresh button) and check again.

As other have alluded, 7-zip is great.

Note: I am going to zip and then unzip a file. Unzip is at the bottom.

My contribution:

Get the

7-Zip Command Line Version

Current URL

http://www.7-zip.org/download.html

The syntax?

You can put the following into a .bat file

"C:\Program Files\7-Zip\7z.exe" a MySuperCoolZipFile.zip "C:\MyFiles\*.jpg" -pmypassword -r -w"C:\MyFiles\" -mem=AES256

I've shown a few options.

-r is recursive. Usually what you want with zip functionality.

a is for "archive". That's the name of the output zip file.

-p is for a password (optional)

-w is a the source directory. This will nest your files correctly in the zip file, without extra folder information.

-mem is the encryption strength.

There are others. But the above will get you running.

NOTE: Adding a password will make the zip file unfriendly when it comes to viewing the file through Windows Explorer. The client may need their own copy of 7-zip (or winzip or other) to view the contents of the file.

EDIT::::::::::::(just extra stuff).

There is a "command line" version which is probably better suited for this: http://www.7-zip.org/download.html

(current (at time of writing) direct link) http://sourceforge.net/projects/sevenzip/files/7-Zip/9.20/7za920.zip/download

So the zip command would be (with the command line version of the 7 zip tool).

"C:\WhereIUnzippedCommandLineStuff\7za.exe" a MySuperCoolZipFile.zip "C:\MyFiles\*.jpg" -pmypassword -r -w"C:\MyFiles\" -mem=AES256

Now the unzip portion: (to unzip the file you just created)

"C:\WhereIUnzippedCommandLineStuff\7zipCommandLine\7za.exe" e MySuperCoolZipFile.zip "*.*" -oC:\SomeOtherFolder\MyUnzippedFolder -pmypassword -y -r

As an alternative to the "e" argument, there is a x argument.

  e: Extract files from archive (without using directory names)
  x: eXtract files with full paths

Simple way to differentiate UTF-8 and UTF-16 is to identify commonalities between them.

Other than sharing same unicode number for given character, each one is their own format.

UTF-8 try to represent, every unicode number given to character with one byte(If it is ASCII), else 2 two bytes, else 4 bytes and so on...

UTF-16 try to represent, every unicode number given to character with two byte to start with. If two bytes are not sufficient, then uses 4 bytes. IF that is also not sufficient, then uses 6 bytes.

Theoretically, UTF-16 is more space efficient, but in practical UTF-8 is more space efficient as most of the characters(98% of data) for processing are ASCII and UTF-8 try to represent them with single byte and UTF-16 try to represent them with 2 bytes.

Also, UTF-8 is superset of ASCII encoding. So every app that expects ASCII data would also accepted by UTF-8 processor. This is not true for UTF-16. UTF-16 could not understand ASCII, and this is big hurdle for UTF-16 adoption.

Another point to note is, all UNICODE as of now could be fit in 4 bytes of UTF-8 maximum(Considering all languages of world). This is same as UTF-16 and no real saving in space compared to UTF-8 ( https://stackoverflow.com/a/8505038/3343801 )

So, people use UTF-8 where ever possible.

The disadvantages of document.write mainly depends on these 3 factors:

a) Implementation

The document.write() is mostly used to write content to the screen as soon as that content is needed. This means it happens anywhere, either in a JavaScript file or inside a script tag within an HTML file. With the script tag being placed anywhere within such an HTML file, it is a bad idea to have document.write() statements inside script blocks that are intertwined with HTML inside a web page.

b) Rendering

Well designed code in general will take any dynamically generated content, store it in memory, keep manipulating it as it passes through the code before it finally gets spit out to the screen. So to reiterate the last point in the preceding section, rendering content in-place may render faster than other content that may be relied upon, but it may not be available to the other code that in turn requires the content to be rendered for processing. To solve this dilemma we need to get rid of the document.write() and implement it the right way.

c) Impossible Manipulation

Once it's written it's done and over with. We cannot go back to manipulate it without tapping into the DOM.

Enable billing for Google project fixed the problem.

-1 isn't special in the sense that the sequence is read backwards, it rather wraps around the ends. Such that minus one means zero minus one, exclusive (and, for a positive step value, the sequence is read "from left to right".

so for i = [1, 2, 3, 4], i[2:-1] means from item two to the beginning minus one (or, 'around to the end'), which results in [3]. The -1th element, or element 0 backwards 1 is the last 4, but since it's exclusive, we get 3.

I hope this is somewhat understandable.

I was also suffering from the same issue. Finally I resolved it by setting binary value in capabilites as shown below. At run time it uses this value so it is must to set.

DesiredCapabilities capability = DesiredCapabilities.firefox();
capability.setCapability("platform", Platform.ANY);
capability.setCapability("binary", "/ms/dist/fsf/PROJ/firefox/16.0.0/bin/firefox"); //for linux

//capability.setCapability("binary", "C:\\Program Files\\Mozilla  Firefox\\msfirefox.exe"); //for windows                
WebDriver    currentDriver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capability);

And you are done!!! Happy coding :)

Back in the old days of Python, to call a function with arbitrary arguments, you would use apply:

apply(f,args,kwargs)

apply still exists in Python2.7 though not in Python3, and is generally not used anymore. Nowadays,

f(*args,**kwargs)

is preferred. The multiprocessing.Pool modules tries to provide a similar interface.

Pool.apply is like Python apply, except that the function call is performed in a separate process. Pool.apply blocks until the function is completed.

Pool.apply_async is also like Python's built-in apply, except that the call returns immediately instead of waiting for the result. An AsyncResult object is returned. You call its get() method to retrieve the result of the function call. The get() method blocks until the function is completed. Thus, pool.apply(func, args, kwargs) is equivalent to pool.apply_async(func, args, kwargs).get().

In contrast to Pool.apply, the Pool.apply_async method also has a callback which, if supplied, is called when the function is complete. This can be used instead of calling get().

For example:

import multiprocessing as mp
import time

def foo_pool(x):
    time.sleep(2)
    return x*x

result_list = []
def log_result(result):
    # This is called whenever foo_pool(i) returns a result.
    # result_list is modified only by the main process, not the pool workers.
    result_list.append(result)

def apply_async_with_callback():
    pool = mp.Pool()
    for i in range(10):
        pool.apply_async(foo_pool, args = (i, ), callback = log_result)
    pool.close()
    pool.join()
    print(result_list)

if __name__ == '__main__':
    apply_async_with_callback()

may yield a result such as

[1, 0, 4, 9, 25, 16, 49, 36, 81, 64]

Notice, unlike pool.map, the order of the results may not correspond to the order in which the pool.apply_async calls were made.

So, if you need to run a function in a separate process, but want the current process to block until that function returns, use Pool.apply. Like Pool.apply, Pool.map blocks until the complete result is returned.

If you want the Pool of worker processes to perform many function calls asynchronously, use Pool.apply_async. The order of the results is not guaranteed to be the same as the order of the calls to Pool.apply_async.

Notice also that you could call a number of different functions with Pool.apply_async (not all calls need to use the same function).

In contrast, Pool.map applies the same function to many arguments. However, unlike Pool.apply_async, the results are returned in an order corresponding to the order of the arguments.

There is a refresh all option in the Pivot Table tool bar. That is enough. Dont have to do anything else.

Press ctrl+alt+F5

There don't seem to be a variable which holds exactly what you want.

However, quoting the docs:

Also available, inventory_dir is the pathname of the directory holding Ansible’s inventory host file, inventory_file is the pathname and the filename pointing to the Ansible’s inventory host file.

playbook_dir contains the playbook base directory.

And finally, role_path will return the current role’s pathname (since 1.8). This will only work inside a role.

Dependent on your setup, those or the $ pwd -based solution might be enough.

If you want to round corners with transparent background, the best approach is using ClipRRect.

return ClipRRect(
  borderRadius: BorderRadius.circular(40.0),
  child: Container(
    height: 800.0,
    width: double.infinity,
    color: Colors.blue,
    child: Center(
      child: new Text("Hi modal sheet"),
    ),
  ),
);

Regarding <link /> and <style />, you don't have a choice, they must be in the <head /> section (see one and two).

Regarding <script /> it can appear both in <head /> and <body /> (see three), usually it is best practice to put them in the <head /> since they are not really "content" (where "content" is what the user sees on screen), they are more something which "works on" the "content".

W3C's HTML4 specification FTW!

You can achieve this using the location object.

location.href = "http://someurl"; 

Your reference to "0x31 = 1" makes me think you're actually trying to convert ASCII values to strings - in which case you should be using something like Encoding.ASCII.GetString(Byte[])

Let's say you have an array of data:

n = [1    2   3   4   6   12  18  51  69  81  ]

then you can 'foreach' it like this:

for i = n, i, end

This will echo every element in n (but replacing the i with more interesting stuff is also possible of course!)

Best solution is put this before showing progressbar or progressDialog

if (getApplicationContext().getWindow().getDecorView().isShown()) {

  //Show Your Progress Dialog

}

The usage info:

Usage: brew switch <formula> <version>

Example:

brew switch mysql 5.5.29

You can find the versions installed on your system with info.

brew info mysql

And to see the available versions to install, you can provide a dud version number, as brew will helpfully respond with the available version numbers:

brew switch mysql 0

Update (15.10.2014):

The brew versions command has been removed from brew, but, if you do wish to use this command first run brew tap homebrew/boneyard.

The recommended way to install an old version is to install from the homebrew/versions repo as follows:

$ brew tap homebrew/versions
$ brew install mysql55

For detailed info on all the ways to install an older version of a formula read this answer.

I agree with Jim Blizard. The database is not the part of your technology stack that should send emails. For example, what if you send an email but then roll back the change that triggered that email? You can't take the email back.

It's better to send the email in your application code layer, after your app has confirmed that the SQL change was made successfully and committed.

Keep in mind that display will depend on culture. And while in most cases all other answers are correct, it did not work for me. Culture issue will also cause different problems with jQuery datepicker, if attached.

If you wish to force the format escape / in the following manner:

@Html.TextBoxFor(model => model.dtArrivalDate, "{0:MM\\/dd\\/yyyy}")

If not escaped for me it show 08-01-2010 vs. expected 08/01/2010.

Also if not escaped jQuery datepicker will select different defaultDate, in my instance it was May 10, 2012.

I like the first response, but for me it's weird. When attempting to check just after page load for the mouse, I have to put in at least a 500 millisecond delay for it to work:

$(window).on('load', function() {
    setTimeout(function() {
        $('img:hover').fadeOut().fadeIn();
    }, 500);
});

I have made a hybrid approach from some of the answers given to this and other similar posts:

This solution checks if a PDF reader app is installed and does the following: - If a reader is installed, download the PDF file to the device and start a PDF reader app - If no reader is installed, ask the user if he wants to view the PDF file online through Google Drive

NOTE! This solution uses the Android DownloadManager class, which was introduced in API9 (Android 2.3 or Gingerbread). This means that it doesn't work on Android 2.2 or earlier.

I wrote a blog post about it here, but I've provided the full code below for completeness:

Defining a Fragment

create xml file for fragment view fragment_abc.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView" />

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button" />

</LinearLayout>

create fragment ABCFragment.java

import androidx.fragment.app.Fragment;

public class FooFragment extends Fragment {
// The onCreateView method is called when Fragment should create its View object hierarchy,
// either dynamically or via XML layout inflation. 

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle 
savedInstanceState) {
    // Defines the xml file for the fragment
    return inflater.inflate(R.layout.fragment_abc, parent, false);
}

// This event is triggered soon after onCreateView().
// Any view setup should occur here.  E.g., view lookups and attaching view listeners.
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    // Setup any handles to view objects here
    // EditText etFoo = (EditText) view.findViewById(R.id.etFoo);
}
}

Add frameLayout in your activity

<FrameLayout
   android:id="@+id/your_placeholder"
   android:layout_width="match_parent"
   android:layout_height="match_parent">

now in activity, add following method

protected void setFragment() {
    // Begin the transaction
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    // Replace the contents of the container with the new fragment
    ft.replace(R.id.fragment_container, new ABCFragment());
    // or ft.add(R.id.your_placeholder, new ABCFragment());
    // Complete the changes added above
    ft.commit();
}

Here no need to depend only on binary or any other format... one flexible built in function is available That prints whichever format you want in your program.. Integer.toString(int,representation);

Integer.toString(100,8) // prints 144 --octal representation

Integer.toString(100,2) // prints 1100100 --binary representation

Integer.toString(100,16) //prints 64 --Hex representation

Here is my sugestion:

Dim i As integer, j as integer

With Worksheets("TimeOut")
    i = 26
    Do Until .Cells(8, i).Value = ""
        For j = 9 to 100 ' I do not know how many rows you will need it.'
            .Cells(j, i).Formula = "YourVolFormulaHere"
            .Cells(j, i + 1).Formula = "YourCapFormulaHere"
        Next j

        i = i + 2
    Loop
 End With

You can directly delete the column with just

del variable_name['year']

I guess you will get ORA-01741: illegal zero-length identifier if you use the following

SELECT "" AS Contact  FROM Customers;

And if you use the following 2 statements, you will be getting the same null value populated in the column.

SELECT '' AS Contact FROM Customers; OR SELECT null AS Contact FROM Customers;

You may also try the following code with exception handling. Here you have a method removeLast(String s, int n) (it is actually an modified version of masud.m's answer). You have to provide the String s and how many char you want to remove from the last to this removeLast(String s, int n) function. If the number of chars have to remove from the last is greater than the given String length then it throws a StringIndexOutOfBoundException with a custom message -

public String removeLast(String s, int n) throws StringIndexOutOfBoundsException{

        int strLength = s.length();

        if(n>strLength){
            throw new StringIndexOutOfBoundsException("Number of character to remove from end is greater than the length of the string");
        }

        else if(null!=s && !s.isEmpty()){

            s = s.substring(0, s.length()-n);
        }

        return s;

    }

You can do it so easy in Kotlin:

 alert("Testing alerts") {
    title = "Alert"
    yesButton { toast("Yess!!!") }
    noButton { }
}.show()

for German Layout (Deutsches Layout) the default is:

for line Comment: strg + Numpad(/)

for block Comment: strg+shift+Numpad(/)

It can be done using inner query Like this

$query = "SELECT * 
            FROM (SELECT Category  
                FROM currency_rates                 
                ORDER BY id DESC) as rows               
            GROUP BY currency";

Why not do string suppression with triple quotes:

>>> s = """my string with "some" double quotes"""
>>> print s
my string with "some" double quotes

Can't you just change working directory within the python script using os.chdir(target)? I agree, I can't see any way of doing it from the jar command itself.

If you don't want to permanently change directory, then store the current directory (using os.getcwd())in a variable and change back afterwards.

You can use

<mat-checkbox [attr.checked] = "myCondition ? 'checked' : null">

if the checked attribute is set to null, it gets removed from the html tag

or you can use Vega's anwser which should work too (mine is a completion that can be usefull if you don't want to link it with ngModel)

CAST uses ANSI standard. In case of portability, this will work on other platforms. CONVERT is specific to sql server. But is very strong function. You can specify different styles for dates

public class Factorial2 {
    public static long factorial(long x) {
        if (x < 0) 
            throw new IllegalArgumentException("x must be >= 0");
        if (x <= 1) 
            return 1;  // Stop recursing here
        else 
           return x * factorial(x-1);  // Recurse by calling ourselves
    }
}

You can use Convert.ChangeType() - It allows you to use runtime information on any IConvertible type to change representation formats. Not all conversions are possible, though, and you may need to write special case logic if you want to support conversions from types that are not IConvertible.

The corresponding code (without exception handling or special case logic) would be:

Ship ship = new Ship();
string value = "5.5";
PropertyInfo propertyInfo = ship.GetType().GetProperty("Latitude");
propertyInfo.SetValue(ship, Convert.ChangeType(value, propertyInfo.PropertyType), null);

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

I tied this in the handler to make it work:

void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (e.Source is TabControl)
    {
      //do work when tab is changed
    }
}

if you are uploading binary file such as csv, use below format to upload file

curl -X POST \
    'http://localhost:8080/workers' \
    -H 'authorization: eyJhbGciOiJIUzI1NiIsInR5cCI6ImFjY2VzcyIsInR5cGUiOiJhY2Nlc3MifQ.eyJ1c2VySWQiOjEsImFjY291bnRJZCI6MSwiaWF0IjoxNTExMzMwMzg5LCJleHAiOjE1MTM5MjIzODksImF1ZCI6Imh0dHBzOi8veW91cmRvbWFpbi5jb20iLCJpc3MiOiJmZWF0aGVycyIsInN1YiI6ImFub255bW91cyJ9.HWk7qJ0uK6SEi8qSeeB6-TGslDlZOTpG51U6kVi8nYc' \
    -H 'content-type: application/x-www-form-urlencoded' \
    --data-binary '@/home/limitless/Downloads/iRoute Masters - Workers.csv'

Using another trait:

trait ATrait {
    function calc($v) {
        return $v+1;
    }
}

class A {
    use ATrait;
}

trait BTrait {
    function calc($v) {
        $v++;
        return parent::calc($v);
    }
}

class B extends A {
    use BTrait;
}

print (new B())->calc(2); // should print 4

In PHP, strings are bytestreams. What exactly are you trying to do?

Re: edit

Ps. Why do I need this at all!? Well I need to send via fputs() bytearray to server written in java...

fputs takes a string as argument. Most likely, you just need to pass your string to it. On the Java side of things, you should decode the data in whatever encoding, you're using in php (the default is iso-8859-1).

set linesize 3000

set wrap off

set termout off

set pagesize 0 embedded on

set trimspool on

Try with all above values.

I changed from "... extends ActionBarActivity" to "... extends AppCompatActivity" and tried cleaning, restarting, Invalidate Caches / Restart and wasn't getting anywhere. All my versions were up to the latest.

What finally solved it was making sure my import was correct:

import android.support.v7.app.AppCompatActivity;

For some reason it didn't get set up automatically like I was used to and I had to add it manually.

Hope that helps someone!

When speaking with remote machines, Ansible by default assumes you are using SSH keys. SSH keys are encouraged but password authentication can also be used where needed by supplying the option --ask-pass. If using sudo features and when sudo requires a password, also supply --ask-become-pass (previously --ask-sudo-pass which has been deprecated).

Never used the feature but the docs say you can.

You can also import the data via the "Import Dataset" tab in RStudio, under "global environment." Use the text data option in the drop down list and select your .RData file from the folder. Once the import is complete, it will display the data in the console. Hope this helps.

just change the containing package of your applicationContext.xml file.
 applicationContext.xml must be in src package not in your project package.
 e.g. 
     src(main package)
         com.yourPackageName(package within src)
         classes etc.
     applicationContext.xml(within src but outside of yourPackage or we can say 
                            parallel to yourPackage name)

Although there won't be any remaining transaction in the case, as @Johan said, you can see the current transaction list in InnoDB with the query below if you want.

SELECT * FROM information_schema.innodb_trx\G

From the document:

The INNODB_TRX table contains information about every transaction (excluding read-only transactions) currently executing inside InnoDB, including whether the transaction is waiting for a lock, when the transaction started, and the SQL statement the transaction is executing, if any.

Consider the second script. If you import it in another one, the instructions, as at "global level", will be executed.

I'm late to the party. But how about one liner:

data, err := ioutil.ReadAll(os.Stdin)

and press ctrl+d (EOT) once input is entered on command line.

I took @Dmitriusan's answer and made it into an alias:

alias docker-run-prev-container='prev_container_id="$(docker ps -aq | head -n1)" && docker commit "$prev_container_id" "prev_container/$prev_container_id" && docker run -it --entrypoint=bash "prev_container/$prev_container_id"'

Add this into your ~/.bashrc aliases file, and you'll have a nifty new docker-run-prev-container alias which'll drop you into a shell in the previous container.

Helpful for debugging failed docker builds.

Well quite same question and there is also an answer =)

Or you check the navigator with some javascript and generate / add a css file with javascript

I think that is the event you need. componentWillReceiveProps triggers whenever your component receive something through props. From there you can have your checking then do whatever you want to do.

The solution of creating a new HTML file with HTML (Web Forms) Designer worked for that file but not for other, individual HTML files that I wanted to edit.

I did find the Open With option in the Open File dialogue and was able to select the HTML (Web Forms) Editor there. Having clicked the "Set as Default" option in that window, VS then remembered to use that editor when I opened other HTML files.

Best answer I found

To get the remote ip address the quickest way possible. You must have to use a downloader, or create a server on your computer.

The downsides to using this simple code: (which is recommended) is that it will take 3-5 seconds to get your Remote IP Address because the WebClient when initialized always takes 3-5 seconds to check for your proxy settings.

 public static string GetIP()
 {
            string externalIP = "";
            externalIP = new WebClient().DownloadString("http://checkip.dyndns.org/");
            externalIP = (new Regex(@"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"))
                                           .Matches(externalIP)[0].ToString();
            return externalIP;
 }

Here is how I fixed it.. (first time still takes 3-5 seconds) but after that it will always get your Remote IP Address in 0-2 seconds depending on your connection.

public static WebClient webclient = new WebClient();
public static string GetIP()
{
    string externalIP = "";
    externalIP = webclient.DownloadString("http://checkip.dyndns.org/");
    externalIP = (new Regex(@"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"))
                                   .Matches(externalIP)[0].ToString();
    return externalIP;
}

A string to char array is as simple as

String str = "someString"; 
char[] charArray = str.toCharArray();

Can you explain a little more on what you are trying to do?

* Update *

if I am understanding your new comment, you can use a byte array and example is provided.

byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();

for (byte b : bytes) {
   System.out.format("0x%x ", b);
}

With the following output

0x65 0x10 0xf3 0x29

You just need to write the line of code to convert your string to int.

 int convertedVal = Integer.parseInt(YOUR STR);

For this lint warning, as for all other lint warnings, note that you can get a fuller explanation than just what is in the one line error message; you don't have to search the web for more info.

If you are using lint via Eclipse, either open the lint warnings view, where you can select the lint error and see a longer explanation, or invoke the quick fix (Ctrl-1) on the error line, and one of the suggestions is "Explain this issue", which will also pop up a fuller explanation. If you are not using Eclipse, you can generate an HTML report from lint (lint --html <filename>) which includes full explanations next to the warnings, or you can ask lint to explain a particular issue. For example, the issue related to allowBackup has the id AllowBackup (shown at the end of the error message), so the fuller explanation is:

$ ./lint --show AllowBackup
AllowBackup
-----------
Summary: Ensure that allowBackup is explicitly set in the application's
manifest

Priority: 3 / 10
Severity: Warning
Category: Security

The allowBackup attribute determines if an application's data can be backed up and restored, as documented here.

By default, this flag is set to true. When this flag is set to true, application data can be backed up and restored by the user using adb backup and adb restore.

This may have security consequences for an application. adb backup allows users who have enabled USB debugging to copy application data off of the device. Once backed up, all application data can be read by the user. adb restore allows creation of application data from a source specified by the user. Following a restore, applications should not assume that the data, file permissions, and directory permissions were created by the application itself.

Setting allowBackup="false" opts an application out of both backup and restore.

To fix this warning, decide whether your application should support backup and explicitly set android:allowBackup=(true|false)

Are u sure u want to remove only last character. What if the user press backspace from the middle of the word.. Its better to get the value from the field and replace the divs html. On keyup

$("#div").html($("#input").val());

#Try without dot notation
sample_dict = {'name': 'John', 'age': 29}
print(sample_dict['name']) # John
print(sample_dict['age']) # 29

If you only want to verify that issuer of UserCert.pem is actually Intermediate.pem do the following (example uses: OpenSSL 1.1.1):

openssl verify -no-CAfile -no-CApath -partial_chain -trusted Intermediate.pem UserCert.pem

and you will get:

UserCert.pem: OK

or

UserCert.pem: verification failed

I have modified AsyncTask class to handle creation of progressDialog at the same context .I think following code will be more reusable. (it can be called from any activity just pass context,target File,dialog message)

public static class DownloadTask extends AsyncTask<String, Integer, String> {
    private ProgressDialog mPDialog;
    private Context mContext;
    private PowerManager.WakeLock mWakeLock;
    private File mTargetFile;
    //Constructor parameters :
    // @context (current Activity)
    // @targetFile (File object to write,it will be overwritten if exist)
    // @dialogMessage (message of the ProgresDialog)
    public DownloadTask(Context context,File targetFile,String dialogMessage) {
        this.mContext = context;
        this.mTargetFile = targetFile;
        mPDialog = new ProgressDialog(context);

        mPDialog.setMessage(dialogMessage);
        mPDialog.setIndeterminate(true);
        mPDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        mPDialog.setCancelable(true);
        // reference to instance to use inside listener
        final DownloadTask me = this;
        mPDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
            @Override
            public void onCancel(DialogInterface dialog) {
                me.cancel(true);
            }
        });
        Log.i("DownloadTask","Constructor done");

The string you are returning is not valid JSON. The names in the objects needs to be quoted and the whole string needs to be put in { … } to form an object. JSON also cannot contain something like new Date(). JSON is just a small subset of JavaScript that has only strings, numbers, objects, arrays, true, false and null.

See the JSON grammar for more information.

The best bet is to stash the changes and switch branch. For switching branches, you need a clean state. So stash them, checkout a new branch and apply the changes on the new branch and commit it

Returns the selected data in structure of object:

console.log($(".leaderMultiSelctdropdown").select2('data'));

Something like:

   [{id:"1",text:"Text",disabled:false,selected:true},{id:"2",text:"Text2",disabled:false,selected:true}]

Returns the selected val:

console.log($('.leaderMultiSelctdropdown').val());
console.log($('.leaderMultiSelctdropdown').select2("val"));

Something like:

["1", "2"]

parseInt is misfeatured like scanf:

parseInt("12 monkeys", 10) is a number with value '12'
+"12 monkeys"              is a number with value 'NaN'
Number("12 monkeys")       is a number with value 'NaN'

On windows 10 i highly recommend to install Linux Bash Shell.

Here is a nice guide to set it up: https://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/

just follow the steps, choose your linux distribution and avoid as much possible to work with node on cmd since obvious instability.

Take in consideration Microsoft strongly warns against adding or modifying Linux files with Windows software, as described here: howtogeek.com/261383/how-to-access-your-ubuntu-bash-files-in-windows-and-your-windows-system-drive-in-bash/

Hope it helps!

Erase an element with index :

vec.erase(vec.begin() + index);

Erase an element with value:

vec.erase(find(vec.begin(),vec.end(),value));

if i understand the question correctly you just want last month and the year it is in:

<?php

  $month = date('m');
  $year = date('Y');
  $last_month = $month-1%12;
  echo ($last_month==0?($year-1):$year)."-".($last_month==0?'12':$last_month);

?>

Here is the example: http://codepad.org/c99nVKG8

After trying all the suggestion given above. Disable this, install that. I opened the xampp-control manager from the start but this this as administrator. After I opened it. MySQL was disable. I disable all of the program and enable apache first and then MySQL. Suddenly start working with no problem.

CreateOrReplaceTempView will create a temporary view of the table on memory it is not presistant at this moment but you can run sql query on top of that . if you want to save it you can either persist or use saveAsTable to save.

first we read data in csv format and then convert to data frame and create a temp view

Reading data in csv format

val data = spark.read.format("csv").option("header","true").option("inferSchema","true").load("FileStore/tables/pzufk5ib1500654887654/campaign.csv")

printing the schema

data.printSchema

data.createOrReplaceTempView("Data")

Now we can run sql queries on top the table view we just created

  %sql select Week as Date,Campaign Type,Engagements,Country from Data order     by Date asc

If you forget to run:

php artisan key:generate

You would be face this error : Composer could not find a composer.json

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

Try this variation:

$(".tr_clone_add").live('click', CloneRow);

function CloneRow()
{
    $(this).closest('.tr_clone').clone().insertAfter(".tr_clone:last");
}

SELECT * FROM Orders where OrderID % 2 = 0;///this is for even numbers

SELECT * FROM Orders where OrderID % 2 != 0;///this is for odd numbers

I found that when I used the this callback function to ignore SSL certificates [System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}

I always got the error message Invoke-WebRequest : The underlying connection was closed: An unexpected error occurred on a send. which sounds like the results you are having.

I found this forum post which lead me to the function below. I run this once inside the scope of my other code and it works for me.

                {
                    return true;
                }
            }
        }
'@ 
    $TAResults=$Provider.CompileAssemblyFromSource($Params,$TASource)
    $TAAssembly=$TAResults.CompiledAssembly
    ## We create an instance of TrustAll and attach it to the ServicePointManager
    $TrustAll = $TAAssembly.CreateInstance("Local.ToolkitExtensions.Net.CertificatePolicy.TrustAll")
    [System.Net.ServicePointManager]::CertificatePolicy = $TrustAll
}

The servlet class should be in the WEB-INF/classes not WEB-INF/src.

PowerShell Alternative

This is an old post and I read through the answers. Still, I found it a bit too painful to output multi-line large text fields unaltered from SSMS. I ended up writing a small C# program for my needs, but got to thinking it could probably be done using the command line. Turns out, it is fairly easy to do so with PowerShell.

Start by installing the SqlServer module from an administrative PowerShell.

Install-Module -Name SqlServer

Use Invoke-Sqlcmd to run your query:

$Rows = Invoke-Sqlcmd -Query "select BigColumn from SomeTable where Id = 123" `
    -As DataRows -MaxCharLength 1000000 -ConnectionString $ConnectionString

This will return an array of rows that you can output to the console as follows:

$Rows[0].BigColumn

Or output to a file as follows:

$Rows[0].BigColumn | Out-File -FilePath .\output.txt -Encoding UTF8

The result is a beautiful un-truncated text written to a file for viewing/editing. I am sure there is a similar command to save back the text to SQL Server, although that seems like a different question.

EDIT: It turns out that there was an answer by @dvlsc that described this approach as a secondary solution. I think because it was listed as a secondary answer, is the reason I missed it in the first place. I am going to leave my answer which focuses on the PowerShell approach, but wanted to at least give credit where it was due.

In your example, the IF statement will run when it is state = true meaning the else part will run when state = false.

if(turnedOn == true) is the same as if(turnedOn)

if(turnedOn == false) is the same as if(!turnedOn)

If you have:

boolean turnedOn = false;

Or

boolean turnedOn;

Then

if(turnedOn)
{

}
else
{
    // This would run!
}

Since Python 2.6.X you might want to use:

"my {0} string: {1}".format("cool", "Hello there!")

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:

GitHub: Permission denied (publickey). fatal: The remote end hung up unexpectedly which links here in the accepted answer (from the original poster, no less): http://help.github.com/linux-set-up-git/

Insert into table(col1,col2) select col1,col2 from table_2;

Please refer to MySQL documentation on INSERT Statement

It all depends on your definition of correct. There are many ways in which you can evaluate your coding style. Readability is an important one (for me). That is why I would use the my_function way of writing function names and variable names.

It's very weird. The Width & Height properties don't shrink when queried (either in code or using the properties sheet), but apparently they DO change.

I noticed that if I use the properties sheet and change the width from the standard 15 to, say, 14 and then BACK to 15, it fixes it.

The code below works for me (and has an amusing visual effect on the sheet: you click, it shrinks, the screen flickers, and it expands back).

MY SOLUTION in code (on the click event for the checkbox):

Dim myCtrl As OLEObject
For Each myCtrl In ActiveSheet.OLEObjects
  myLab = myCtrl.Name
  myCtrl.Height = 14 ' to "wake up" the property.
  myCtrl.Height = 15 ' to reset it back to normal
  myCtrl.Width = 12 ' just making sure
Next myCtrl

Inserting text to some bit in code:

ctrl + v, (selecting text on multiple lines), I, (type something I want), ESC

Recording a macro to edit text and running it N times:

q, a (or some other letter), (do the things I want to record), q, ESC,
(type N, as in the number of times I want to run the macro), @, a

If you use Windows container and you want change any file, you can get and use Vim in Powershell console easily.

To shelled to the Windows Docker container with PowerShell:

docker exec -it <name> powershell

• First get Chocolatey package manager

  Invoke-WebRequest https://chocolatey.org/install.ps1 -UseBasicParsing | Invoke-Expression;

• Install Vim

  choco install vim

• Refresh ENVIRONMENTAL VARIABLE You can just exit and shell back to the container

• Go to file location and Vim it vim file.txt

Here, we

• upgraded to JUnit 4.5,
• wrote annotations to tag each test class or method which needed a working service,
• wrote handlers for each annotation which contained static methods to implement the setup and teardown of the service,
• extended the usual Runner to locate the annotations on tests, adding the static handler methods into the test execution chain at the appropriate points.

select t1.* from 
(select * from TABLE Where CCC='D' AND DDD='X') as t1,
(select * from TABLE Where CCC<>'D' AND DDD='X') as t2

Another way to do this!

   SELECT CONVERT(varchar(11),getdate(),101)  -- mm/dd/yyyy

   SELECT CONVERT(varchar(11),getdate(),103)  -- dd/mm/yyyy

Check this . I am assuming D30.SPGD30_TRACKED_ADJUSTMENT_X is of datetime datatype .
That is why i am using CAST() function to make it as an character expression because CHARINDEX() works on character expression.
Also I think there is no need of OR condition.

select case when CHARINDEX('-',cast(D30.SPGD30_TRACKED_ADJUSTMENT_X as varchar )) > 0 

then 'Score Calculation - '+CONVERT(VARCHAR(11), D30.SPGD30_TRACKED_ADJUSTMENT_X, 103)
end

EDIT:

select case when CHARINDEX('-',D30.SPGD30_TRACKED_ADJUSTMENT_X) > 0 
then 'Score Calculation - '+
CONVERT( VARCHAR(11), CAST(D30.SPGD30_TRACKED_ADJUSTMENT_X as DATETIME) , 103)
end

See this link for conversion to other date formats: https://www.w3schools.com/sql/func_sqlserver_convert.asp

I made a fiddle implementing (essentially) above ideas outlined by iman. Here is how it looks when you mouse over the second ipsum in return ipsum*ipsum - ...

The variables which are in scope are highlighted where they are declared (with different colors for different scopes). The lorem with red border is a shadowed variable (not in scope, but be in scope if the other lorem further down the tree wouldn't be there.)

I'm using esprima library to parse the JavaScript, and estraverse, escodegen, escope (utility libraries on top of esprima.) The 'heavy lifting' is done all by those libraries (the most complex being esprima itself, of course.)

How it works

ast = esprima.parse(sourceString, {range: true, sourceType: 'script'});

makes the abstract syntax tree. Then,

analysis = escope.analyze(ast);

generates a complex data structure encapsulating information about all the scopes in the program. The rest is gathering together the information encoded in that analysis object (and the abstract syntax tree itself), and making an interactive coloring scheme out of it.

So the correct answer is actually not "no", but "yes, but". The "but" being a big one: you basically have to rewrite significant parts of the chrome browser (and it's devtools) in JavaScript. JavaScript is a Turing complete language, so of course that is possible, in principle. What is impossible is doing the whole thing without using the entirety of your source code (as a string) and then doing highly complex stuff with that.

The difference is :

"If you use !=, it returns sub-second. If you use <>, it takes 7 seconds to return. Both return the right answer."

I believe the way to do this is $location.url('/RouteTo/Login');

Edit for Clarity

Say my route for my login view was /Login, I would say $location.url('/Login') to navigate to that route.

For locations outside of the Angular app (i.e. no route defined), plain old JavaScript will serve:

window.location = "http://www.my-domain.com/login"

This is my solution(There is a nested LinearLayout):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/item"
            android:layout_width="match_parent"
            android:layout_height="47dp"
            android:background="@drawable/box_arrow_top_bg"
            android:gravity="center"
            android:text="????"
            android:textColor="#666"
            android:textSize="16sp" />
    </LinearLayout>

</LinearLayout>

Given a dataset

df <- data.frame( sex = c('M', 'M', 'F', 'F', 'M'), 
                  occupation = c('analyst', 'dentist', 'dentist', 'analyst', 'cook') )

you can subset rows

df[df$sex == 'M',] # To get all males
df[df$occupation == 'analyst',] # All analysts

etc.

If you want to get number of rows, just call the function nrow such as

nrow(df[df$sex == 'M',])

The simplest solution that I could find using Typescript 3.1 in 3 steps is:

1) Make interface

interface IOriginal {
    original: { [key: string]: any }
}

2) Make a typed copy

let copy: IOriginal = (original as any)[key];

3) Use anywhere (JSX included)

<input customProp={copy} />

I created a event based solution based on Bjorn Tipling's answer:

(function(doc){
    'use strict';

    window.onscroll = function (event) {
        if (isEndOfElement(doc.body)){
            sendNewEvent('end-of-page-reached');
        }
    };

    function isEndOfElement(element){
        //visible height + pixel scrolled = total height 
        return element.offsetHeight + element.scrollTop >= element.scrollHeight;
    }

    function sendNewEvent(eventName){
        var event = doc.createEvent('Event');
        event.initEvent(eventName, true, true);
        doc.dispatchEvent(event);
    }
}(document));

And you use the event like this:

document.addEventListener('end-of-page-reached', function(){
    console.log('you reached the end of the page');
});

BTW: you need to add this CSS for javascript to know how long the page is

html, body {
    height: 100%;
}

I had the same problem. I had used

git format-patch <commit_hash>

to create the patch. My main problem was patch was failing due to some conflicts, but I could not see any merge conflict in the file content. I had used git am --3way <patch_file_path> to apply the patch.

The correct command to apply the patch should be:

git am --3way --ignore-space-change <patch_file_path>

If you execute the above command for patching, it will create a merge conflict if patch apply fails. Then you can fix the conflict in your files, like the same way merge conflicts are resolved for git merge

The simplest is using the OpenCV Mat class:

img=cv::Scalar(blue_value, green_value, red_value);

where img was defined as a cv::Mat.

Uninstall the app, and re-install and it should work!

Faster option:

The following code will copy your Pandas DF to postgres DB much faster than df.to_sql method and you won't need any intermediate csv file to store the df.

Create an engine based on your DB specifications.

Create a table in your postgres DB that has equal number of columns as the Dataframe (df).

Data in DF will get inserted in your postgres table.

from sqlalchemy import create_engine
import psycopg2 
import io

if you want to replace the table, we can replace it with normal to_sql method using headers from our df and then load the entire big time consuming df into DB.

engine = create_engine('postgresql+psycopg2://username:password@host:port/database')

df.head(0).to_sql('table_name', engine, if_exists='replace',index=False) #drops old table and creates new empty table

conn = engine.raw_connection()
cur = conn.cursor()
output = io.StringIO()
df.to_csv(output, sep='\t', header=False, index=False)
output.seek(0)
contents = output.getvalue()
cur.copy_from(output, 'table_name', null="") # null values become ''
conn.commit()
