0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

This would do the trick, returning the values at indeces 0, 2 and 3.

Array.FindAll(arr, Function(s) s.ToLower().StartsWith("ra"))

This is the universal and best solution for this:

If WScript.Arguments.Count <> 1 Then WScript.Quit 1
RunAsAdmin
Main

Sub RunAsAdmin()
    Set Shell = CreateObject("WScript.Shell")
    Set Env = Shell.Environment("VOLATILE")
    If Shell.Run("%ComSpec% /C ""NET FILE""", 0, True) <> 0 Then
        Env("CurrentDirectory") = Shell.CurrentDirectory
        ArgsList = ""
        For i = 1 To WScript.Arguments.Count
            ArgsList = ArgsList & """ """ & WScript.Arguments(i - 1)
        Next
        CreateObject("Shell.Application").ShellExecute WScript.FullName, """" & WScript.ScriptFullName & ArgsList & """", , "runas", 5
        WScript.Sleep 100
        Env.Remove("CurrentDirectory")
        WScript.Quit
    End If
    If Env("CurrentDirectory") <> "" Then Shell.CurrentDirectory = Env("CurrentDirectory")
End Sub

Sub Main()
    'Your code here!
End Sub

Advantages:

1) The parameter injection is not possible.
2) The number of arguments does not change after the elevation to administrator and then you can check them before you elevate yourself.
3) You know for real and immediately if the script runs as an administrator. For example, if you call it from a control panel uninstallation entry, the RunAsAdmin function will not run unnecessarily because in that case you are already an administrator. Same thing if you call it from a script already elevated to administrator.
4) The window is kept at its current size and position, as it should be.
5) The current directory doesn't change after obtained administrative privileges.

Disadvantages: Nobody

For me, it worked to use Newtonsoft.Json:

using Newtonsoft.Json;
// ...
var output = JsonConvert.SerializeObject(ListOfMyObject);

If @Cybernate's solution doesn't work, try breaking the trigger off in to it's own function so you can reference it.

clickHandler = function(event){
  if (click++ == 49)
    canvas.removeEventListener('click',clickHandler);
}
canvas.addEventListener('click',clickHandler);

I played a long time with things like ls -1 | xargs -P to parallelize my playbooks runs. But to get a prettier display, and simplicity I wrote a simple Python tool to do it, ansible-parallel.

It goes like this:

pip install ansible-parallel
ansible-parallel *.yml

To answer precisely to the original question (how to run some tasks first, and the rest in parallel), it can be solved by removing the 3 includes and running:

ansible-playbook say_hi.yml
ansible-parallel load_balancers.yml webservers.yml dbservers.yml

The reliable/standardized way to parse FTP directory listing is by using MLSD command, which by now should be supported by all recent/decent FTP servers.

import ftplib
f = ftplib.FTP()
f.connect("localhost")
f.login()
ls = []
f.retrlines('MLSD', ls.append)
for entry in ls:
    print entry

The code above will print:

modify=20110723201710;perm=el;size=4096;type=dir;unique=807g4e5a5; tests
modify=20111206092323;perm=el;size=4096;type=dir;unique=807g1008e0; .xchat2
modify=20111022125631;perm=el;size=4096;type=dir;unique=807g10001a; .gconfd
modify=20110808185618;perm=el;size=4096;type=dir;unique=807g160f9a; .skychart
...

Starting from python 3.3, ftplib will provide a specific method to do this:

• http://bugs.python.org/issue11072
• http://hg.python.org/cpython/file/67053b135ed9/Lib/ftplib.py#l535

Assuming you are using this plugin, you are misusing the .set method. .set must be passed the name of the key as a string as well as the value. I suppose you meant to write:

$.session.set("userName", $("#uname").val());

This sets the userName key in session storage to the value of the input, and allows you to retrieve it using:

$.session.get('userName');

It is not always about the compilation flags, I have the same error on gentoo when using distcc.

The reason is that on distcc server is using a not-hardened profile and on client the profile is hardened. Check this discussion: https://forums.gentoo.org/viewtopic-p-7463994.html

Use the zzz format specifier to get the timezone offset as hours and minutes. You also want to use the HH format specifier to get the hours in 24 hour format.

DateTime.Now.ToString("yyyy-MM-ddTHH:mm:sszzz")

Result:

2011-08-09T23:49:58+02:00

Some culture settings uses periods instead of colons for time, so you might want to use literal colons instead of time separators:

DateTime.Now.ToString("yyyy-MM-ddTHH':'mm':'sszzz")

Custom Date and Time Format Strings

With personal experience of using the following code within a Stored Procedure which Hashed a SP Variable I can confirm, although undocumented, this combination works 100% as per my example:

@var=SUBSTRING(master.dbo.fn_varbintohexstr(HashBytes('SHA2_512', @SPvar)), 3, 128)

On Python 2.8 type(list) is list returns false
I would suggest comparing the type in this horrible way:

if type(a) == type([]) :
  print "variable a is a list"

Stopping the timer doesn't mean that it won't be called again, depending on when you stop the timer, the timer_tick may still be queued on the message loop for the form. What will happen is that you'll get one more tick that you may not be expecting. What you can do is in your timer_tick, check the Enabled property of your timer before executing the Timer_Tick method.

Did you check the WCF traces? WCF has a tendency to swallow exceptions and only return the last exception, which is the timeout that you're getting, since the end point didn't return anything meaningful.

Because there are protocol overheads, and because there are other users of the network.

If you want to load a test resource file as a string with just few lines of code and without any extra dependencies, this does the trick:

public String loadResourceAsString(String fileName) throws IOException {
    Scanner scanner = new Scanner(getClass().getClassLoader().getResourceAsStream(fileName));
    String contents = scanner.useDelimiter("\\A").next();
    scanner.close();
    return contents;
}

"\\A" matches the start of input and there's only ever one. So this parses the entire file contents and returns it as a string. Best of all, it doesn't require any 3rd party libraries (like IOUTils).

In case anyone would be searching - I created utility for automated import of xlsx files into google spreadsheet: xls2sheets. One can do it automatically via setting up the cronjob for ./cmd/sheets-refresh, readme describes it all. Hope that would be of use.

You could run: mvn exec:exec -Dexec.args="arg1".

This will pass the argument arg1 to your program.

You should specify the main class fully qualified, for example, a Main.java that is in a package test would need

mvn exec:java  -Dexec.mainClass=test.Main

By using the -f parameter, as decribed here, you can also run it from other directories.

mvn exec:java -Dexec.mainClass=test.Main -f folder/pom.xm

For multiple arguments, simply separate them with a space as you would at the command line.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="arg1 arg2 arg3"

For arguments separated with a space, you can group using 'argument separated with space' inside the quotation marks.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="'argument separated with space' 'another one'"

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming

Update March 2013

Git 1.8.2 added the possibility to track branches.

"git submodule" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 

If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".

Also see Vogella's tutorial on submodules for general information on submodules.

Note:

git submodule add -b . [URL to Git repo];
                    ^^^

See git submodule man page:

A special value of . is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.

See commit b928922727d6691a3bdc28160f93f25712c565f6:

submodule add: If --branch is given, record it in .gitmodules

This allows you to easily record a submodule.<name>.branch option in .gitmodules when you add a new submodule. With this patch,

$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>

reduces to

$ git submodule add -b <branch> <repository> [<path>]

This means that future calls to

$ git submodule update --remote ...

will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):

A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log within that submodule.

So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:

• cd in the submodule
• git fetch/pull to make sure it has the latest commits on the right branch
• cd back in the parent repo
• add and commit in order to record the new commit of the submodule.

gitslave (that you already looked at) seems to be the best fit, including for the commit operation.

It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).

Other alternatives are detailed here.

Where the Android-SDK is installed depends on how you installed it.

1. If you downloaded the SDK through their website and then dragged/dropped the Application to your Applications folder, it's most likely here:

   /Applications/ADT/sdk (as it is in your case).

2. If you installed the SDK using Homebrew (brew cask install android-sdk), then it's located here:

   /usr/local/Caskroom/android-sdk/{YOUR_SDK_VERSION_NUMBER}

3. If the SDK was installed automatically as part of Android Studio then it's located here:

   /Users/{YOUR_USER_NAME}/Library/Android/sdk

Once you know the location, open a terminal window and enter the following (changing out the path to the SDK to be however you installed it):

export ANDROID_HOME={YOUR_PATH}

Once you have this set, you need to add this to the PATH environment variable:

export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

Lastly apply these changes by re-sourcing .bash_profile:

source ~/.bash_profile

4. Type - echo $ANDROID_HOME to check if the home is set.

echo $ANDROID_HOME

You can only change the language on the whole server, not individual databases. However if you need to support the UK you can run the following command before all inputs and outputs:

set language 'british english'

Or if you are having issues entering datatimes from your application you might want to consider a universal input type such as

1-Dec-2008

If you really want Jackson to return a date with another time zone than UTC (and I myself have several good arguments for that, especially when some clients just don't get the timezone part) then I usually do:

ObjectMapper mapper = new ObjectMapper();
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
dateFormat.setTimeZone(TimeZone.getTimeZone("CET"));
mapper.getSerializationConfig().setDateFormat(dateFormat);
// ... etc

It has no adverse effects on those that understand the timezone-p

This is an old question, but here's another way to do it.

You can modify the R code itself instead of the chunk options, by wrapping the source call in suppressPackageStartupMessages(), suppressMessages(), and/or suppressWarnings(). E.g:

```{r echo=FALSE}
suppressWarnings(suppressMessages(suppressPackageStartupMessages({
source("C:/Rscripts/source.R")
})
```

You can also put those functions around your library() calls inside the "source.R" script.

Null OR an empty string?

if (!empty($user)) {}

Use empty().

After realizing that $user ~= $_POST['user'] (thanks matt):

var uservariable='<?php 
    echo ((array_key_exists('user',$_POST)) || (!empty($_POST['user']))) ? $_POST['user'] : 'Empty Username Input';
?>';

const urlParams = new URLSearchParams(window.location.search);

urlParams.set('order', 'date');

window.location.search = urlParams;

.set first agrument is the key, the second one is the value.

The most beginner-friendly solution is:

Drag a Timer from the Toolbox, give it a Name, set your desired Interval, and set "Enabled" to True. Then double-click the Timer and Visual Studio (or whatever you are using) will write the following code for you:

private void wait_Tick(object sender, EventArgs e)
{
    refreshText(); // Add the method you want to call here.
}

No need to worry about pasting it into the wrong code block or something like that.

If you're only getting these to manually pass into df.set_index(), that's unnecessary. Just directly do df.set_index['your_col_name', drop=False], already.

It's very rare in pandas that you need to get an index as a Python list (unless you're doing something pretty funky, or else passing them back to NumPy), so if you're doing this a lot, it's a code smell that you're doing something wrong.

The most important thing to remember:

The only way to get a constant, variable (any result) from TenorFlow is the session.

Knowing this everything else is easy:

Both tf.Session.run() and tf.Tensor.eval() get results from the session where tf.Tensor.eval() is a shortcut for calling tf.get_default_session().run(t)

I would also outline the method tf.Operation.run() as in here:

After the graph has been launched in a session, an Operation can be executed by passing it to tf.Session.run(). op.run() is a shortcut for calling tf.get_default_session().run(op).

It's usually just easier to skip the mouse altogether--or it would be if Sublime didn't mess up multiselect when word wrapping. Here's the official documentation on using the keyboard and mouse for multiple selection. Since it's a bit spread out, I'll summarize it:

Where shortcuts are different in Sublime Text 3, I've made a note. For v3, I always test using the latest dev build; if you're using the beta build, your experience may be different.

If you lose your selection when switching tabs or windows (particularly on Linux), try using Ctrl + U to restore it.

Mouse

Windows/Linux

Building blocks:

• Positive/negative:
  • Add to selection: Ctrl
  • Subtract from selection: Alt In early builds of v3, this didn't work for linear selection.
• Selection type:
  • Linear selection: Left Click
  • Block selection: Middle Click or Shift + Right Click On Linux, middle click pastes instead by default.

Combine as you see fit. For example:

• Add to selection: Ctrl + Left Click (and optionally drag)
• Subtract from selection: Alt + Left Click This didn't work in early builds of v3.
• Add block selection: Ctrl + Shift + Right Click (and drag)
• Subtract block selection: Alt + Shift + Right Click (and drag)

Mac OS X

Building blocks:

• Positive/negative:
  • Add to selection: ?
  • Subtract from selection: ?? (only works with block selection in v3; presumably bug)
• Selection type:
  • Linear selection: Left Click
  • Block selection: Middle Click or ? + Left Click

Combine as you see fit. For example:

• Add to selection: ? + Left Click (and optionally drag)
• Subtract from selection: ?? + Left Click (and drag--this combination doesn't work in Sublime Text 3, but supposedly it works in 2)
• Add block selection: ?? + Left Click (and drag)
• Subtract block selection: ??? + Left Click (and drag)

Keyboard

Windows

• Return to single selection mode: Esc
• Extend selection upward/downward at all carets: Ctrl + Alt + Up/Down
• Extend selection leftward/rightward at all carets: Shift + Left/Right
• Move all carets up/down/left/right, and clear selection: Up/Down/Left/Right
• Undo the last selection motion: Ctrl + U
• Add next occurrence of selected text to selection: Ctrl + D
• Add all occurrences of the selected text to the selection: Alt + F3
• Rotate between occurrences of selected text (single selection): Ctrl + F3 (reverse: Ctrl + Shift + F3)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: Ctrl + Shift + L

Linux

• Return to single selection mode: Esc
• Extend selection upward/downward at all carets: Alt + Up/Down Note that you may be able to hold Ctrl as well to get the same shortcuts as Windows, but Linux tends to use Ctrl + Alt combinations for global shortcuts.
• Extend selection leftward/rightward at all carets: Shift + Left/Right
• Move all carets up/down/left/right, and clear selection: Up/Down/Left/Right
• Undo the last selection motion: Ctrl + U
• Add next occurrence of selected text to selection: Ctrl + D
• Add all occurrences of the selected text to the selection: Alt + F3
• Rotate between occurrences of selected text (single selection): Ctrl + F3 (reverse: Ctrl + Shift + F3)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: Ctrl + Shift + L

Mac OS X

• Return to single selection mode: ? (that's the Mac symbol for Escape)
• Extend selection upward/downward at all carets: ^??, ^?? (See note)
• Extend selection leftward/rightward at all carets: ??/??
• Move all carets up/down/left/right and clear selection: ?, ?, ?, ?
• Undo the last selection motion: ?U
• Add next occurrence of selected text to selection: ?D
• Add all occurrences of the selected text to the selection: ^?G
• Rotate between occurrences of selected text (single selection): ??G (reverse: ???G)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: ??L

Notes for Mac users

On Yosemite and El Capitan, ^?? and ^?? are system keyboard shortcuts by default. If you want them to work in Sublime Text, you will need to change them:

1. Open System Preferences.
2. Select the Shortcuts tab.
3. Select Mission Control in the left listbox.
4. Change the keyboard shortcuts for Mission Control and Application windows (or disable them). I use ^?? and ^??. They defaults are ^? and ^?; adding ^ to those shortcuts triggers the same actions, but slows the animations.

In case you're not familiar with Mac's keyboard symbols:

• ? is the escape key
• ^ is the control key
• ? is the option key
• ? is the shift key
• ? is the command key
• ? et al are the arrow keys, as depicted

I followed these steps on Centos 7 for MongoDB 4.2. (Remote user)

Update mongod.conf file

vi /etc/mongod.conf
   net:
     port: 27017
     bindIp: 0.0.0.0 
   security:
     authorization: enabled

Start MongoDB service demon

systemctl start mongod

Open MongoDB shell

mongo

Execute this command on the shell

use admin
db.createUser(
  {
    user: 'admin',
    pwd: 'YouPassforUser',
    roles: [ { role: 'root', db: 'admin' } ]
  }
);

Remote root user has been created. Now you can test this database connection by using any MongoDB GUI tool from your dev machine. Like Robo 3T

Right click on My Computer >> Properties >> Advanced system settings >> System Properties window will get displayed Under Advanced >> Environment Variables

Click on New to set Environment Variables

Variable name: JAVA_HOME Variable value: C:\Program Files\Java\jdk1.8.0_121

Variable name: M2 Variable value: %M2_HOME%\bin

Variable name: M2_HOME Variable value: C:\Program Files\Apache Software Foundation\apache-maven-3.5.0

Variable name: Path Variable value: %M2_HOME%\bin

Then click on Ok, ok, ok. Now restart you command prompt and check again with “mvn –version” to verify the mvn is running, you may restart your system also.

It's Working...... Enjoy :)

When reseting the "Indent" of the list you have to keep in mind that browsers might have different defaults. To make life a lot easier always start off with a "Normalize" file.

The purpose of using these CSS "Normalize" files is to set everything to a know set of values and not relying on what the browser's defaults. Chrome might have a different set of defaults to say FireFox. This way you know that your pages will always display the same no matter what browser you are using, and you know the values to "Reset" your elements.

Now if you are only concerned about lists in particular I would not simply set the padding to 0, this will put your bullets "Outside" of the list not inside like you would expect.

Another thing to keep in mind is not to use the "px" or pixel unit of measurement, you want to use the "em" unit instead. The "em" unit is based on font-size, this way no matter what the font-size is you are guaranteed that the bullet will be on the inside of the list, if you use a pixel offset then on larger font sizes the bullets will be on the outside of the list.

So here is a snippet of the "Normalize" script I use. First set everything to a known value so you know what to set it back to.

ul{
   margin: 0;
   padding: 1em; /* Set the distance from the list edge to 1x the font size */
   list-style-type: disc;
   list-style-position: outside;
   list-style-image: none;
}

Here's what worked for me:

select visits, activations, simulations, simulations/activations
   as sims_per_visit, activations/visits*100
   as adoption_rate, simulations/activations*100
   as completion_rate, duration/60
   as minutes, m1 as month, Wk1 as week, Yr1 as year 

from
(
    (select count(*) as visits, year(stamp) as Yr1, week(stamp) as Wk1, month(stamp)
    as m1 from sessions group by week(stamp), year(stamp)) as t3

    join

    (select count(*) as activations, year(stamp) as Yr2, week(stamp) as Wk2,
    month(stamp) as m2 from sessions where activated='1' group by week(stamp),
    year(stamp)) as t4

    join

    (select count(*) as simulations, year(stamp) as Yr3 , week(stamp) as Wk3,
    month(stamp) as m3 from sessions where simulations>'0' group by week(stamp),
    year(stamp)) as t5

    join

    (select avg(duration) as duration, year(stamp) as Yr4 , week(stamp) as Wk4,
    month(stamp) as m4 from sessions where activated='1' group by week(stamp),
    year(stamp)) as t6
)
where Yr1=Yr2 and Wk1=Wk2 and Wk1=Wk3 and Yr1=Yr3 and Yr1=Yr4 and Wk1=Wk4

I used joins, not unions (I needed different columns for each query, a join puts it all in the same column) and I dropped the quotation marks (compared to what Liam was doing) because they were giving me errors.

Thanks! I couldn't have pulled that off without this page! PS: Sorry I don't know how you're getting your statements formatted with colors. etc.

For better understanding run the above code and compare the results..

Well, this question appears on top of search results, so I believe we need code example here. Here's the Python code:

import cv2

def apply_mask(frame, mask):
    """Apply binary mask to frame, return in-place masked image."""
    return cv2.bitwise_and(frame, frame, mask=mask)

Mask and frame must be the same size, so pixels remain as-is where mask is 1 and are set to zero where mask pixel is 0.

And for C++ it's a little bit different:

cv::Mat inFrame; // Original (non-empty) image
cv::Mat mask; // Original (non-empty) mask

// ...

cv::Mat outFrame;  // Result output
inFrame.copyTo(outFrame, mask);

Using Array.from I wrote a Typescript function that maps the values:

function mapKeys<T, V, U>(m: Map<T, V>, fn: (this: void, v: V) => U): Map<T, U> {
  function transformPair([k, v]: [T, V]): [T, U] {
    return [k, fn(v)]
  }
  return new Map(Array.from(m.entries(), transformPair));
}

const m = new Map([[1, 2], [3, 4]]);
console.log(mapKeys(m, i => i + 1));
// Map { 1 => 3, 3 => 5 }

Add this to your css:

.row-centered {
   text-align:center;
}


.col-centered {
   display:inline-block;
   float:none;
   /* reset the text-align */
   text-align:left;
   /* inline-block space fix */
   margin-right:-4px;
}

Then, in your HTML code:

    <div class=" row row-centered">
        <div class="col-*-*  col-centered>
           Your content
        </div>
    </div>

Preferred Approach

In Swift 2.0 Apple added availability checking using a far more convenient syntax (Read more here). Now you can check the OS version with a cleaner syntax:

if #available(iOS 9, *) {
    // Then we are on iOS 9
} else {
    // iOS 8 or earlier
}

This is the preferred over checking respondsToSelector etc (What's New In Swift). Now the compiler will always warn you if you aren't guarding your code properly.

Pre Swift 2.0

New in iOS 8 is NSProcessInfo allowing for better semantic versioning checks.

Deploying on iOS 8 and greater

For minimum deployment targets of iOS 8.0 or above, use NSProcessInfo operatingSystemVersion or isOperatingSystemAtLeastVersion.

This would yield the following:

let minimumVersion = NSOperatingSystemVersion(majorVersion: 8, minorVersion: 1, patchVersion: 2)
if NSProcessInfo().isOperatingSystemAtLeastVersion(minimumVersion) {
    //current version is >= (8.1.2)
} else {
    //current version is < (8.1.2)
}

Deploying on iOS 7

For minimum deployment targets of iOS 7.1 or below, use compare with NSStringCompareOptions.NumericSearch on UIDevice systemVersion.

This would yield:

let minimumVersionString = "3.1.3"
let versionComparison = UIDevice.currentDevice().systemVersion.compare(minimumVersionString, options: .NumericSearch)
switch versionComparison {
    case .OrderedSame, .OrderedDescending:
        //current version is >= (3.1.3)
        break
    case .OrderedAscending:
        //current version is < (3.1.3)
        fallthrough
    default:
        break;
}

String.prototype.format = function () {
    var formatted = this;
    for (var arg in arguments) {
        formatted = formatted.split('{' + arg + '}').join(arguments[arg]);
    }
    return formatted;
};

USAGE:

'Hello {0}!'.format('Word')                 ->     Hello World!

'He{0}{0}o World!'.format('l')            ->     Hello World!

'{0} {1}!'.format('Hello', 'Word')     ->     Hello World!

'{0}!'.format('Hello {1}', 'Word')     ->     Hello World!

Use "winsw" which was written for Glassfish v3 but works well with Java programs in general.

Below python program should work to access hive tables from python:

import commands

cmd = "hive -S -e 'SELECT * FROM db_name.table_name LIMIT 1;' "

status, output = commands.getstatusoutput(cmd)

if status == 0:
   print output
else:
   print "error"

In my particular case it was easier to do this:

 panel.setOpaque(true);
 panel.setBackground(new Color(0,0,0,0,)): // any color with alpha 0 (in this case the color is black

I solved it with a custom data tag, because a title attribute is required anyway.

$("[data-tooltip]").each(function(i, e) {
    var tag = $(e);
    if (tag.is("[title]") === false) {
        tag.attr("title", "");
    }
});

$(document).tooltip({
    items: "[data-tooltip]",
    content: function () {
        return $(this).attr("data-tooltip");
    }
});

Like this it is html conform and the tooltips are only shown for wanted tags.

Use active class with label to make it auto select and use checked="" .

   <label class="btn btn-primary  active" value="regular"  style="width:47%">
   <input  type="radio" name="service" checked=""  > Regular </label>
   <label class="btn btn-primary " value="express" style="width:46%">
   <input type="radio" name="service"> Express </label>

Why write complicated code when you could make it simple?

Indeed, if you are absolutely going to use the Optional class, the most simple code is what you have already written ...

if (user.isPresent())
{
    doSomethingWithUser(user.get());
}

This code has the advantages of being

1. readable
2. easy to debug (breakpoint)
3. not tricky

Just because Oracle has added the Optional class in Java 8 doesn't mean that this class must be used in all situation.

If the Toggle Visual Space icon shall be added to a Visual Studio toolbar of your choice, because it shall be turned on and off via mouse click, then follow this instruction:

1. Customize the desired toolbar

   

2. Click on Customize...

3. Click on Add Command...

4. Go to Edit and chose Toggle Visual Space

   

5. Click on OK

If I understand you, perhaps you don't need an array of zeroes; rather, you need a hash. The hash keys will be the values in the other array and the hash values will be the number of times the value exists in the other array:

use strict;
use warnings;

my @other_array = (0,0,0,1,2,2,3,3,3,4);
my %tallies;
$tallies{$_} ++ for @other_array;

print "$_ => $tallies{$_}\n" for sort {$a <=> $b} keys %tallies;    

Output:

0 => 3
1 => 1
2 => 2
3 => 3
4 => 1

To answer your specific question more directly, to create an array populated with a bunch of zeroes, you can use the technique in these two examples:

my @zeroes = (0) x 5;            # (0,0,0,0,0)

my @zeroes = (0) x @other_array; # A zero for each item in @other_array.
                                 # This works because in scalar context
                                 # an array evaluates to its size.

It probably shouldn't matter. You are going to get much better performance designing your algorithm to use a fixed number of threads (eg, 4 or 8 if you have 4 or 8 processors). You can do this with work queues, asynchronous IO, or something like libevent.

Alternatively, you can also do this ...

One thing that might not always be obvious to some is that a cross join with an empty table (or result set) results in empty table (M x N; hence M x 0 = 0)

A full outer join will always have rows unless both M and N are 0.

        }
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());

You should execute sh -c echo $PWD; generally sh -c will execute shell commands.

(In fact, system(foo) is defined as execl("sh", "sh", "-c", foo, NULL) and thus works for shell built-ins.)

If you just want the value of PWD, use getenv, though.

As far as i had gone it is mostly depend on compiler but in general most cases the value is pre assumed as 0 by the compliers.
I got garbage value in case of VC++ while TC gave value as 0. I Print it like below

int i;
printf('%d',i);

Window.close( ) does not work as it used to. Can be seen here:

If you are sending alphanumeric data try changing

'Content-Type': 'multipart/form-data'

to

'Content-Type': 'application/x-www-form-urlencoded'

If you are sending non-alphanumeric data try to remove 'Content-Type' at all.

If it still does not work, consider trying request-promise (at least to test whether it is really axios problem or not)

Use DateTime

$datetime = new DateTime('tomorrow');
echo $datetime->format('Y-m-d H:i:s');

Or:

$datetime = new DateTime('2013-01-22');
$datetime->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

Or:

$datetime = new DateTime('2013-01-22');
$datetime->add(new DateInterval("P1D"));
echo $datetime->format('Y-m-d H:i:s');

Or in PHP 5.4+:

echo (new DateTime('2013-01-22'))->add(new DateInterval("P1D"))
                                 ->format('Y-m-d H:i:s');

You can effectively remove scientific notation in printing with this code:

options(scipen=999)

Using a for loop, how do I access the loop index, from 1 to 5 in this case?

Use enumerate to get the index with the element as you iterate:

for index, item in enumerate(items):
    print(index, item)

And note that Python's indexes start at zero, so you would get 0 to 4 with the above. If you want the count, 1 to 5, do this:

for count, item in enumerate(items, start=1):
    print(count, item)

Unidiomatic control flow

What you are asking for is the Pythonic equivalent of the following, which is the algorithm most programmers of lower-level languages would use:

index = 0            # Python's indexing starts at zero
for item in items:   # Python's for loops are a "for each" loop 
    print(index, item)
    index += 1

Or in languages that do not have a for-each loop:

index = 0
while index < len(items):
    print(index, items[index])
    index += 1

or sometimes more commonly (but unidiomatically) found in Python:

for index in range(len(items)):
    print(index, items[index])

Use the Enumerate Function

Python's enumerate function reduces the visual clutter by hiding the accounting for the indexes, and encapsulating the iterable into another iterable (an enumerate object) that yields a two-item tuple of the index and the item that the original iterable would provide. That looks like this:

for index, item in enumerate(items, start=0):   # default is zero
    print(index, item)

This code sample is fairly well the canonical example of the difference between code that is idiomatic of Python and code that is not. Idiomatic code is sophisticated (but not complicated) Python, written in the way that it was intended to be used. Idiomatic code is expected by the designers of the language, which means that usually this code is not just more readable, but also more efficient.

Getting a count

Even if you don't need indexes as you go, but you need a count of the iterations (sometimes desirable) you can start with 1 and the final number will be your count.

for count, item in enumerate(items, start=1):   # default is zero
    print(item)

print('there were {0} items printed'.format(count))

The count seems to be more what you intend to ask for (as opposed to index) when you said you wanted from 1 to 5.

Breaking it down - a step by step explanation

To break these examples down, say we have a list of items that we want to iterate over with an index:

items = ['a', 'b', 'c', 'd', 'e']

Now we pass this iterable to enumerate, creating an enumerate object:

enumerate_object = enumerate(items) # the enumerate object

We can pull the first item out of this iterable that we would get in a loop with the next function:

iteration = next(enumerate_object) # first iteration from enumerate
print(iteration)

And we see we get a tuple of 0, the first index, and 'a', the first item:

(0, 'a')

we can use what is referred to as "sequence unpacking" to extract the elements from this two-tuple:

index, item = iteration
#   0,  'a' = (0, 'a') # essentially this.

and when we inspect index, we find it refers to the first index, 0, and item refers to the first item, 'a'.

>>> print(index)
0
>>> print(item)
a

Conclusion

• Python indexes start at zero
• To get these indexes from an iterable as you iterate over it, use the enumerate function
• Using enumerate in the idiomatic way (along with tuple unpacking) creates code that is more readable and maintainable:

So do this:

for index, item in enumerate(items, start=0):   # Python indexes start at zero
    print(index, item)

You can do it perfectly using this:

I just want to add some remarks to the great answer by Fredrik.

The Java Language Specification in Section 4.3.1 states

An object is a class instance or an array.

So array has indeed a very special role in Java. I do wonder why.

One could argue that current implementation array is/was important for a better performance. But than it is an internal structure, which should not be exposed.

They could of course have masked the property as a method call and handled it in the compiler but I think it would have been even more confusing to have a method on something that isn't a real class.

I agree with Fredrik, that a smart compiler optimazation would have been the better choice. This would also solve the problem, that even if you use a property for arrays, you have not solved the problem for strings and other (immutable) collection types, because, e.g., string is based on a char array as you can see on the class definition of String:

public final class String implements java.io.Serializable, Comparable<String>, CharSequence {           
    private final char value[]; // ...

And I do not agree with that it would be even more confusing, because array does inherit all methods from java.lang.Object.

As an engineer I really do not like the answer "Because it has been always this way." and wished there would be a better answer. But in this case it seems to be.

tl;dr

In my opinion, it is a design flaw of Java and should not have implemented this way.

You want to check whether Examples exists in Range("A1").Value If it fails then to check Example right? I think mycode will work perfect. Please check.

Sub test()
Dim string1 As String, string2 As String
string1 = "Examples"
string2 = "Example"
If InStr(1, Range("A1").Value, string1) > 0 Then
    x = 1
ElseIf InStr(1, Range("A1").Value, string2) > 0 Then
    x = 2
End If

End Sub

for a big database you should either remove the database from the disk (after you stop the engine first I guess) or use in Cypher something like:

MATCH (n)
OPTIONAL MATCH (n)-[r]-()
WITH n,r LIMIT 50000
DELETE n,r
RETURN count(n) as deletedNodesCount

Here is a codepen, it worked for me.

I was searching for the simplest solution for embedding the YT video within an iframe, and I feel this is it.

What I needed was to have the video appear in a modal window and stop playing when it was closed

Here is the code : (from: https://codepen.io/anon/pen/GBjqQr)

    <div><a href="#" class="play-video">Play Video</a></div>
    <div><a href="#" class="stop-video">Stop Video</a></div>
    <div><a href="#" class="pause-video">Pause Video</a></div>

    <iframe class="youtube-video" width="560" height="315" src="https://www.youtube.com/embed/glEiPXAYE-U?enablejsapi=1&version=3&playerapiid=ytplayer" frameborder="0" allowfullscreen></iframe>

$('a.play-video').click(function(){
    $('.youtube-video')[0].contentWindow.postMessage('{"event":"command","func":"' + 'playVideo' + '","args":""}', '*');
});

$('a.stop-video').click(function(){
    $('.youtube-video')[0].contentWindow.postMessage('{"event":"command","func":"' + 'stopVideo' + '","args":""}', '*');
});

$('a.pause-video').click(function(){
    $('.youtube-video')[0].contentWindow.postMessage('{"event":"command","func":"' + 'pauseVideo' + '","args":""}', '*');
});

Additionally, if you want it to autoplay in a DOM-object that is not yet visible, such as a modal window, if I used the same button to play the video that I was using to show the modal it would not work so I used THIS:

https://www.youtube.com/embed/EzAGZCPSOfg?autoplay=1&enablejsapi=1&version=3&playerapiid=ytplayer

Note: The ?autoplay=1& where it's placed and the use of the '&' before the next property to allow the pause to continue to work.

There is even easier way how to work with JSONP using jQuery

$.getJSON("http://example.com/something.json?callback=?", function(result){
   //response data are now in the result variable
   alert(result);
});

The ? on the end of the URL tells jQuery that it is a JSONP request instead of JSON. jQuery registers and calls the callback function automatically.

For more detail refer to the jQuery.getJSON documentation.

Okay, found it!

I'm using timezone-js. this is the code:

var dt = new timezoneJS.Date("2012/04/10 10:10:30 +0000", 'Europe/London');

console.debug(dt); //return formatted date-time in asia/jakarta

There are a number of "is methods" on strings. islower() and isupper() should meet your needs:

>>> 'hello'.islower()
True

>>> [m for m in dir(str) if m.startswith('is')]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']

Here's an example of how to use those methods to classify a list of strings:

>>> words = ['The', 'quick', 'BROWN', 'Fox', 'jumped', 'OVER', 'the', 'Lazy', 'DOG']
>>> [word for word in words if word.islower()]
['quick', 'jumped', 'the']
>>> [word for word in words if word.isupper()]
['BROWN', 'OVER', 'DOG']

My problem ended up being that my data transfer objects were too complex. Start withsimple properties like public long Id { get; set; } and once you get that working than start adding additional stuff as needed.

Your view names need to be unique even if they are pointing to the same view method.

app.add_url_rule('/',
                 view_func=Main.as_view('main'),
                 methods = ['GET'])

app.add_url_rule('/<page>/',
                 view_func=Main.as_view('page'),
                 methods = ['GET'])

They are used for different things. The alt attribute is used instead of the image. If the image can't be shown, and in screen readers.

The title attribute is shown along with the image, typically as a hover tooltip.

One should not be used "instead" of the other. Each should be used properly, to do the things they were designed to do.

This is a supplemental answer for those arriving here based on the question title (like I did) and don't need to deal with the security issues related to saving passwords.

How to use Shared Preferences

User settings are generally saved locally in Android using SharedPreferences with a key-value pair. You use the String key to save or look up the associated value.

Write to Shared Preferences

String key = "myInt";
int valueToSave = 10;

SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(context);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt(key, valueToSave).commit();

Use apply() instead of commit() to save in the background rather than immediately.

Read from Shared Preferences

String key = "myInt";
int defaultValue = 0;

SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(context);
int savedValue = sharedPref.getInt(key, defaultValue);

The default value is used if the key isn't found.

Notes

• Rather than using a local key String in multiple places like I did above, it would be better to use a constant in a single location. You could use something like this at the top of your settings activity:

    final static String PREF_MY_INT_KEY = "myInt";
  

• I used an int in my example, but you can also use putString(), putBoolean(), getString(), getBoolean(), etc.

• See the documentation for more details.

• There are multiple ways to get SharedPreferences. See this answer for what to look out for.

int sizepuede= listaoptionVO.size();
for (int i = 0; i < sizepuede; i++) {
    if(listaoptionVO.get(i).getDescripcionRuc()==null){
        listaoptionVO.remove(listaoptionVO.get(i));
        i--;
        sizepuede--;
     }
}

Just use this code. What most are forgeting is to specify max-width as the max-width of the image

img {   
    height: auto;
    width: 100%;
    max-width: 300px;
}

Check this demonstration http://shorturl.at/nBKVY

The $_GET variable is populated from the parameters set in the URL. From the URL http://example.com/test.php?foo=bar&baz=buzz you can get $_GET['foo'] and $_GET['baz']. So to set these variables, you only have to make a link to that URL.

Can I use a field of the type ... and retrieve it after the GET / POST method ...

Yes (haven't you tried?)

Are there any other ways of using hidden fields in PHP?

You mean other ways of retrieving the value? No.
Of course you can use hidden fields for what ever you want.

Btw. input fiels have no end tag. So write either just <input ...> or as self-closing tag <input .../>.

They have the same effect on normal web browser rendering engines, but there is a fundamental difference between them.

As the author writes in a discussion list post:

Think of three different situations:

• web browsers
• blind people
• mobile phones

"Bold" is a style - when you say "bold a word", people basically know that it means to add more, let's say "ink", around the letters until they stand out more amongst the rest of the letters.

That, unfortunately, means nothing to a blind person. On mobile phones and other PDAs, text is already bold because screen resolution is very small. You can't bold a bold without screwing something up.

<b> is a style - we know what "bold" is supposed to look like.

<strong> however is an indication of how something should be understood. "Strong" could (and often does) mean "bold" in a browser, but it could also mean a lower tone for a speaking program like Jaws (for blind people) or be represented by an underline (since you can't bold a bold) on a Palm Pilot.

HTML was never meant to be about styles. Do some searches for "Tim Berners-Lee" and "the semantic web." <strong> is semantic—it describes the text it surrounds (e.g., "this text should be stronger than the rest of the text you've displayed") as opposed to describing how the text it surrounds should be displayed (e.g., "this text should be bold").

Using jQuery 1.9 and above:

$("#mySelect :selected").prop('selected', false);

Yes, $_SERVER["HTTP_X_FORWARDED_FOR"] is how I see my ip when under a proxy on my nginx server.

But your best bet is to run phpinfo() on a page requested from under a proxy so you can look at all the availabe variables and see what is the one that carries your real ip.

If you are using SQL Server (starting with vNext) or Azure SQL Database then you can use the below query.

SELECT TRIM(ColumnName) from TableName;

For other SQL SERVER Database you can use the below query.

SELECT LTRIM(RTRIM(ColumnName)) from TableName

LTRIM - Removes spaces from the left

example: select LTRIM(' test ') as trim = 'test '

RTRIM - Removes spaces from the right

example: select RTRIM(' test ') as trim = ' test'

Or, you could use the margin attribute like this:

    {
    background:#222;
    width:100%;
    height:100px;
    margin-left: 10px;
    margin-right: 10px;
    display:block;
    }

You don't have JSON. You have a JavaScript data structure consisting of objects, an array, some strings and some numbers.

Use JSON.stringify(object) to turn it into (a string of) JSON text.

Apparently this is a known bug of Eclipse. This bug is resolved with the resolution of WONT-FIX. I have no idea why though. here is the link: Eclipse C Console Bug.

From R..'s answer:

However, this is probably a very bad idea, because the resulting type is an array type, but users of it won't see that it's an array type. If used as a function argument, it will be passed by reference, not by value, and the sizeof for it will then be wrong.

Users who don't see that it's an array will most likely write something like this (which fails):

#include <stdio.h>

typedef int twoInts[2];

void print(twoInts *twoIntsPtr);
void intermediate (twoInts twoIntsAppearsByValue);

int main () {
    twoInts a;
    a[0] = 0;
    a[1] = 1;
    print(&a);
    intermediate(a);
    return 0;
}
void intermediate(twoInts b) {
    print(&b);
}

void print(twoInts *c){
    printf("%d\n%d\n", (*c)[0], (*c)[1]);
}

It will compile with the following warnings:

In function ‘intermediate’:
warning: passing argument 1 of ‘print’ from incompatible pointer type [enabled by default]
    print(&b);
     ^
note: expected ‘int (*)[2]’ but argument is of type ‘int **’
    void print(twoInts *twoIntsPtr);
         ^

And produces the following output:

0
1
-453308976
32767

A debugging script (jquery solution based on the answer above by hashchange)

function getAttributes ( $node ) {
      $.each( $node[0].attributes, function ( index, attribute ) {
      console.log(attribute.name+':'+attribute.value);
   } );
}

getAttributes($(this));  // find out what attributes are available

you can set it in the main index.php

    define('ENVIRONMENT', 'development');
/*
 *---------------------------------------------------------------
 * ERROR REPORTING
 *---------------------------------------------------------------
 *
 * Different environments will require different levels of error reporting.
 * By default development will show errors but testing and live will hide them.
 */

if (defined('ENVIRONMENT'))
{
    switch (ENVIRONMENT)
    {
        case 'development':
            error_reporting(E_ALL);
        break;

    case 'testing':
    case 'production':
        error_reporting(0);
    break;

    default:
        exit('The application environment is not set correctly.');
}
}

This solution may not be optimal or pretty, but it works. It reads in an input file line by line, writing each line out to a temporary output file. Whenever it encounters a line that matches what you are looking for, it skips writing that one out. It then renames the output file. I have omitted error handling, closing of readers/writers, etc. from the example. I also assume there is no leading or trailing whitespace in the line you are looking for. Change the code around trim() as needed so you can find a match.

File inputFile = new File("myFile.txt");
File tempFile = new File("myTempFile.txt");

BufferedReader reader = new BufferedReader(new FileReader(inputFile));
BufferedWriter writer = new BufferedWriter(new FileWriter(tempFile));

String lineToRemove = "bbb";
String currentLine;

while((currentLine = reader.readLine()) != null) {
    // trim newline when comparing with lineToRemove
    String trimmedLine = currentLine.trim();
    if(trimmedLine.equals(lineToRemove)) continue;
    writer.write(currentLine + System.getProperty("line.separator"));
}
writer.close(); 
reader.close(); 
boolean successful = tempFile.renameTo(inputFile);

To conditionally check the length of the string, use CASE.

SELECT  CASE WHEN LEN(comments) <= 60 
             THEN comments
             ELSE LEFT(comments, 60) + '...'
        END  As Comments

That's a difficult problem to solve since visually similar PDFs may have a wildly differing structure depending on how they were produced. In the worst case the library would need to basically act like an OCR. On the other hand, the PDF may contain sufficient structure and metadata for easy removal of tables and figures, which the library can be tailored to take advantage of.

I'm pretty sure there are no open source tools which solve your problem for a wide variety of PDFs, but I remember having heard of commercial software claiming to do exactly what you ask for. I'm sure you'll run into them while googling.

The most recommended way to do is to use format method. Read more about it here

a, b = 1, 2

print("a={0},b={1}".format(a, b))

for the best performance and lower memory consumption , try this:

using System;
using System.Diagnostics;
using System.Text;
using System.Text.RegularExpressions;

public class Program
{
    private static Regex digitsOnly = new Regex(@"[^\d]");

    public static void Main()
    {
        Console.WriteLine("Init...");

        string phone = "001-12-34-56-78-90";

        var sw = new Stopwatch();
        sw.Start();
        for (int i = 0; i < 1000000; i++)
        {
            DigitsOnly(phone);
        }
        sw.Stop();
        Console.WriteLine("Time: " + sw.ElapsedMilliseconds);

        var sw2 = new Stopwatch();
        sw2.Start();
        for (int i = 0; i < 1000000; i++)
        {
            DigitsOnlyRegex(phone);
        }
        sw2.Stop();
        Console.WriteLine("Time: " + sw2.ElapsedMilliseconds);

        Console.ReadLine();
    }

    public static string DigitsOnly(string phone, string replace = null)
    {
        if (replace == null) replace = "";
        if (phone == null) return null;
        var result = new StringBuilder(phone.Length);
        foreach (char c in phone)
            if (c >= '0' && c <= '9')
                result.Append(c);
            else
            {
                result.Append(replace);
            }
        return result.ToString();
    }

    public static string DigitsOnlyRegex(string phone)
    {
        return digitsOnly.Replace(phone, "");
    }
}

The result in my computer is:
Init...
Time: 307
Time: 2178

Actually... you can't use a simple regex here, at least not one. You probably need to worry about comments! Someone may write:

<!-- <content> blah </content> -->

You can take two approaches here:

1. Strip all comments out first. Then use the regex approach.
2. Do not use regular expressions and use a context sensitive parsing approach that can keep track of whether or not you are nested in a comment.

Be careful.

I am also not so sure you can match all new lines at once. @Quartz suggested this one:

<content>([^\n]*\n+)+</content>

This will match any content tags that have a newline character RIGHT BEFORE the closing tag... but I'm not sure what you mean by matching all newlines. Do you want to be able to access all the matched newline characters? If so, your best bet is to grab all content tags, and then search for all the newline chars that are nested in between. Something more like this:

<content>.*</content>

BUT THERE IS ONE CAVEAT: regexes are greedy, so this regex will match the first opening tag to the last closing one. Instead, you HAVE to suppress the regex so it is not greedy. In languages like python, you can do this with the "?" regex symbol.

I hope with this you can see some of the pitfalls and figure out how you want to proceed. You are probably better off using an XML parsing library, then iterating over all the content tags.

I know I may not be offering the best solution, but at least I hope you will see the difficulty in this and why other answers may not be right...

UPDATE 1:

Let me summarize a bit more and add some more detail to my response. I am going to use python's regex syntax because it is what I am more used to (forgive me ahead of time... you may need to escape some characters... comment on my post and I will correct it):

To strip out comments, use this regex: Notice the "?" suppresses the .* to make it non-greedy.

Similarly, to search for content tags, use: .*?

Also, You may be able to try this out, and access each newline character with the match objects groups():

<content>(.*?(\n))+.*?</content>

I know my escaping is off, but it captures the idea. This last example probably won't work, but I think it's your best bet at expressing what you want. My suggestion remains: either grab all the content tags and do it yourself, or use a parsing library.

UPDATE 2:

So here is python code that ought to work. I am still unsure what you mean by "find" all newlines. Do you want the entire lines? Or just to count how many newlines. To get the actual lines, try:

#!/usr/bin/python

import re

def FindContentNewlines(xml_text):
    # May want to compile these regexes elsewhere, but I do it here for brevity
    comments = re.compile(r"<!--.*?-->", re.DOTALL)
    content = re.compile(r"<content>(.*?)</content>", re.DOTALL)
    newlines = re.compile(r"^(.*?)$", re.MULTILINE|re.DOTALL)

    # strip comments: this actually may not be reliable for "nested comments"
    # How does xml handle <!--  <!-- --> -->. I am not sure. But that COULD
    # be trouble.
    xml_text = re.sub(comments, "", xml_text)

    result = []
    all_contents = re.findall(content, xml_text)
    for c in all_contents:
        result.extend(re.findall(newlines, c))

    return result

if __name__ == "__main__":
    example = """

<!-- This stuff
ought to be omitted
<content>
  omitted
</content>
-->

This stuff is good
<content>
<p>
  haha!
</p>
</content>

This is not found
"""
    print FindContentNewlines(example)

This program prints the result:

 ['', '<p>', '  haha!', '</p>', '']

The first and last empty strings come from the newline chars immediately preceeding the first <p> and the one coming right after the </p>. All in all this (for the most part) does the trick. Experiment with this code and refine it for your needs. Print out stuff in the middle so you can see what the regexes are matching and not matching.

Hope this helps :-).

PS - I didn't have much luck trying out my regex from my first update to capture all the newlines... let me know if you do.

I've modified Casey's answer to only logoff disconnected sessions by doing the following:

   foreach($Server in $Servers) {
    try {
        query user /server:$Server 2>&1 | select -skip 1 | ? {($_ -split "\s+")[-5] -eq 'Disc'} | % {logoff ($_ -split "\s+")[-6] /server:$Server /V}
    }
    catch {}
    }

Missing a semicolon

if [ -a myApp ];
then
  rm myApp
fi

However, I assume you are checking for existence before deletion to prevent an error message. If so, you can just use rm -f myApp which "forces" delete, i.e. doesn't error out if the file didn't exist.

There is no portable way to get resolution of less than a second in standard C So best you can do is, use the POSIX function gettimeofday().

When I experienced the "An app with identifier XXX is not available" error in trying to switch on iCloud support in Xcode's Capabilities tab, I found that I had to:

• Give my app an explicit custom bundle id,

• Register my app manually at the Member Center, explicitly requesting iCloud support entitlements there.

After that, switching on iCloud support in Xcode worked. So, I suggest trying the same thing. Sometimes, things work better when you do them at the Member Center.

Using all built-ins..

tuple(map(sum, zip(a, b)))

You can use either = or "space". For instance following two commands return the same

git log --author="Developer1"

git log --author "Developer1"

you can use this:

HTML

<input name="userfile" type="file" accept="application/pdf, application/vnd.ms-excel" />

support only .PDF and .XLS files

decimalVar.ToString ("#.##"); // returns "" when decimalVar == 0

or

decimalVar.ToString ("0.##"); // returns "0"  when decimalVar == 0

Under Linux you can create directory in one line:

import os
os.system("mkdir -p {0}".format('mydir'))

This function will return you the date and time in the following format: YYYY:MM:DD:HH:MM:SS. It also works in Node.js.

function getDateTime() {

    var date = new Date();

    var hour = date.getHours();
    hour = (hour < 10 ? "0" : "") + hour;

    var min  = date.getMinutes();
    min = (min < 10 ? "0" : "") + min;

    var sec  = date.getSeconds();
    sec = (sec < 10 ? "0" : "") + sec;

    var year = date.getFullYear();

    var month = date.getMonth() + 1;
    month = (month < 10 ? "0" : "") + month;

    var day  = date.getDate();
    day = (day < 10 ? "0" : "") + day;

    return year + ":" + month + ":" + day + ":" + hour + ":" + min + ":" + sec;

}

look at it is informative [Qualified identifiers

A qualified id-expression is an unqualified id-expression prepended by a scope resolution operator ::, and optionally, a sequence of enumeration, (since C++11)class or namespace names or decltype expressions (since C++11) separated by scope resolution operators. For example, the expression std::string::npos is an expression that names the static member npos in the class string in namespace std. The expression ::tolower names the function tolower in the global namespace. The expression ::std::cout names the global variable cout in namespace std, which is a top-level namespace. The expression boost::signals2::connection names the type connection declared in namespace signals2, which is declared in namespace boost.

The keyword template may appear in qualified identifiers as necessary to disambiguate dependent template names]1

After change our php.ini, make sure to restart Apache web server.

Use IList to get the JArray Count and Use Loop to Convert into List

       var array = result["items"].Value<JArray>();

        IList collection = (IList)array;

        var list = new List<string>();

        for (int i = 0; i < collection.Count; j++)
            {
              list.Add(collection[i].ToString());             
            }                         

I had the same problem, and I was using the following plugin for tests:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <useFile>true</useFile>
        <includes>
            <include>**/*Tests.java</include>
            <include>**/*Test.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*.java</exclude>
        </excludes>
        <junitArtifactName>junit:junit</junitArtifactName>
        <parallel>methods</parallel>
        <threadCount>10</threadCount>
    </configuration>
</plugin>

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

Open Package Manager Console

• View -> Other Windows -> Package Manager Console

Reinstall all packages in ALL PROJECTS of the current solution:

Update-Package -Reinstall

Reinstall all packages in SPECIFIC PROJECT of the current solution (Thanks to unarity and ashes999):

Update-Package -ProjectName 'YourProjectNameGoesHere' -Reinstall

I've figure it out the solution to my problem:

• Step 1: from within the vSphere client, while connected to vCenter1, select the VM and then from "File" menu select "Export"->"Export OVF Template" (Note: make sure the VM is Powered Off otherwise this feature is not available - it will be gray). This action will allow you to save on your machine/laptop the VM (as an .vmdk, .ovf and a .mf file).
• Step 2: Connect to the vCenter2 with your vSphere client and from "File" menu select "Deploy OVF Template..." and then select the location where the VM was saved in the previous step.

That was all!
Thanks!

Try this, It always works, and you will get NO TypeError:

try{

    var i1 = document.getElementById('i1');
    var i2 = document.getElementById('i2');
    var __i = {'user' : document.getElementsByName("username")[0], 'pass' : document.getElementsByName("password")[0] };
    if(  __i.user.value.length >= 1 ) { i1.value = ''; } else { i1.value = 'Acc'; }
    if(  __i.pass.value.length >= 1 ) { i2.value = ''; } else { i2.value = 'Pwd'; }

}catch(e){
    if(e){
    // If fails, Do something else
    }
}

Unfortunately, the best thing I have seen is the jquery.combobox, but it doesn't really look like something I'd really want to use in my web applications. I think there are some usability issues with this control, but as a user I don't think I'd know to start typing for the dropdownlist to turn into a textbox.

I much prefer the Combo Dropdown Box, but it still has some features that I'd want and it's still in alpha. The only think I don't like about this other than its being alpha... is that once I type in the combobox, the original dropdownlist items disappear. However, maybe there is a setting for this... or maybe it could be added fairly easily.

Those are the only two options that I know of. Good luck in your search. I'd love to hear if you find one or if the second option works out for you.

Open CMD or Powershell in Administrator mode, then run...

netstat -ab

The output should be able to point you in the direction of which process is holding port 8080. Entry may likely be 127.0.0.1:8080 You may still have a running instance of Tomcat at port 8080.

You can either use Stop-Process in PowerShell or taskKill in CMD to stop that process and should be able to execute the program at that point.

Removing the line-height indeed makes your text align with your placeholder-text, but it doesn't properly solve your problem since you need to adapt your design to this flaw (it's not a bug). Adding vertical-align won't do the deal either. I haven't tried in all browsers, but it doesn't work in Safari 5.1.4 for sure.

I have heard of a jQuery fix for this, that is not cross-browser placeholder support (jQuery.placeholder), but for styling placeholders, but I haven't found it yet.

In the meantime, you can resolve to the table on this page which shows different browser support for different styles.

Edit: Found the plugin! jquery.placeholder.min.js provides you with both full styling capabilities and cross-browser support into the bargain.

On Debian the best way to do it would be

sudo apt-get install python-pip

You can go fullscreen automatically by putting this code in:

var elem = document.documentElement; if (elem.requestFullscreen) { elem.requestFullscreen() }

note: does not always work for security reasons. but it works for me at least. does not work when inspecting and pasting the code.

My own solution to solve this kind of Enum JPA mapping is the following.

Step 1 - Write the following interface that we will use for all enums that we want to map to a db column:

public interface IDbValue<T extends java.io.Serializable> {

    T getDbVal();

}

Step 2 - Implement a custom generic JPA converter as follows:

import javax.persistence.AttributeConverter;

public abstract class EnumDbValueConverter<T extends java.io.Serializable, E extends Enum<E> & IDbValue<T>>
        implements AttributeConverter<E, T> {

    private final Class<E> clazz;

    public EnumDbValueConverter(Class<E> clazz){
        this.clazz = clazz;
    }

    @Override
    public T convertToDatabaseColumn(E attribute) {
        if (attribute == null) {
            return null;
        }
        return attribute.getDbVal();
    }

    @Override
    public E convertToEntityAttribute(T dbData) {
        if (dbData == null) {
            return null;
        }
        for (E e : clazz.getEnumConstants()) {
            if (dbData.equals(e.getDbVal())) {
                return e;
            }
        }
        // handle error as you prefer, for example, using slf4j:
        // log.error("Unable to convert {} to enum {}.", dbData, clazz.getCanonicalName());
        return null;
    }

}

This class will convert the enum value E to a database field of type T (e.g. String) by using the getDbVal() on enum E, and vice versa.

Step 3 - Let the original enum implement the interface we defined in step 1:

public enum Right implements IDbValue<Integer> {
    READ(100), WRITE(200), EDITOR (300);

    private final Integer dbVal;

    private Right(Integer dbVal) {
        this.dbVal = dbVal;
    }

    @Override
    public Integer getDbVal() {
        return dbVal;
    }
}

Step 4 - Extend the converter of step 2 for the Right enum of step 3:

public class RightConverter extends EnumDbValueConverter<Integer, Right> {
    public RightConverter() {
        super(Right.class);
    }
}

Step 5 - The final step is to annotate the field in the entity as follows:

@Column(name = "RIGHT")
@Convert(converter = RightConverter.class)
private Right right;

Conclusion

IMHO this is the cleanest and most elegant solution if you have many enums to map and you want to use a particular field of the enum itself as mapping value.

For all others enums in your project that need similar mapping logic, you only have to repeat steps 3 to 5, that is:

• implement the interface IDbValue on your enum;
• extend the EnumDbValueConverter with only 3 lines of code (you may also do this within your entity to avoid creating a separated class);
• annotate the enum attribute with @Convert from javax.persistence package.

Hope this helps.

Aha. This turned out to be a simple problem of there being spaces in the path to the script.

Changing the Invoke-Expression line to:

Invoke-Expression "& `"$scriptPath`" $argumentList"

...was enough to get it to kick off. Thanks to Neolisk for your help and feedback!

You don't need to wrap it in a list with [..], just provide the subselection of the columns index:

df.drop(df.columns[[1, 69]], axis=1, inplace=True)

as the index object is already regarded as list-like.

In Oracle, you could do this:

create table D (
  ID numeric(1),
  CODE varchar(2),
  constraint PK_D primary key (ID, CODE)
);

Use of the argmin method for numpy arrays.

import numpy as np
np.argmin(myList)

However, it is not the fastest method: it is 3 times slower than OP's answer on my computer. It may be the most concise one though.

You can use numpy's slicing, simply start:stop:step.

>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])

This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2]         # O(1), constant time
>>> b[:] = 0           # modifying the view changes original array
>>> a                  # original array is modified
array([0, 2, 0, 4, 0])

so if either of the above things are a problem, you can make a copy explicitly:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy()  # explicit copy, O(n)
>>> b[:] = 0           # modifying the copy
>>> a                  # original is intact
array([1, 2, 3, 4, 5])

This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.

An easy approach is to leverage this code:

<a href="javascript:void(0);">Link Title</a>

This approach doesn't force a page refresh, so the scrollbar stays in place. Also, it allows you to programmatically change the onclick event and handle client side event binding using jQuery.

For these reasons, the above solution is better than:

<a href="javascript:myClickHandler();">Link Title</a>
<a href="#" onclick="myClickHandler(); return false;">Link Title</a>

where the last solution will avoid the scroll-jump issue if and only if the myClickHandler method doesn't fail.

They all do different things, since matplotlib uses a hierarchical order in which a figure window contains a figure which may consist of many axes. Additionally, there are functions from the pyplot interface and there are methods on the Figure class. I will discuss both cases below.

pyplot interface

pyplot is a module that collects a couple of functions that allow matplotlib to be used in a functional manner. I here assume that pyplot has been imported as import matplotlib.pyplot as plt. In this case, there are three different commands that remove stuff:

plt.cla() clears an axes, i.e. the currently active axes in the current figure. It leaves the other axes untouched.

plt.clf() clears the entire current figure with all its axes, but leaves the window opened, such that it may be reused for other plots.

plt.close() closes a window, which will be the current window, if not specified otherwise.

Which functions suits you best depends thus on your use-case.

The close() function furthermore allows one to specify which window should be closed. The argument can either be a number or name given to a window when it was created using figure(number_or_name) or it can be a figure instance fig obtained, i.e., usingfig = figure(). If no argument is given to close(), the currently active window will be closed. Furthermore, there is the syntax close('all'), which closes all figures.

methods of the Figure class

Additionally, the Figure class provides methods for clearing figures. I'll assume in the following that fig is an instance of a Figure:

fig.clf() clears the entire figure. This call is equivalent to plt.clf() only if fig is the current figure.

fig.clear() is a synonym for fig.clf()

Note that even del fig will not close the associated figure window. As far as I know the only way to close a figure window is using plt.close(fig) as described above.

Just to add a note that Google Chrome browser has origin attribute for the location. which gives you the entire domain from protocol to the port number as shown in the below screenshot.

No there isn't. If you watch the http traffic and dump the page source you can see that there is an API below the covers, but it's not published nor available for 3rd party apps.

Check this link: https://developers.google.com/gsuite/products for updates.

However, there is an unofficial Python API under active development: https://github.com/kiwiz/gkeepapi

SELECT CASE WHEN COUNT(1) > 0 THEN 1 ELSE 0 END AS [Value]

FROM Sites S

WHERE S.Id = @SiteId and S.Status = 1 AND 
      (S.WebUserId = @WebUserId OR S.AllowUploads = 1)

I like:

Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
myDate.ToString(timeFormat)

Easy to maintain if you need to use it in several parts of your code, date formats always seem to change sooner or later.

If you put this on onDestroy or onStop method. I think that when the activity has been created again the MessageReciver wasn't being created.

@Override 
public void onDestroy (){
    super.onDestroy();
LocalBroadcastManager.getInstance(context).unregisterReceiver(mMessageReceiver);

}

I recently spent a week studying lot of solutions to validate my forms in an app. I started with all the most stared one but I couldn't find one who was working as I was expected. After few days, I became quite frustrated until i found a very new and amazing plugin: https://github.com/kettanaito/react-advanced-form

The developper is very responsive and his solution, after my research, merit to become the most stared one from my perspective. I hope it could help and you'll appreciate.

TIMESTAMP is 4 bytes Vs 8 bytes for DATETIME.

But like scronide said it does have a lower limit of the year 1970. It's great for anything that might happen in the future though ;)

I may have missed something here, but why can't you just declare your string with the desired size? For example, in my VBA code I often use something like:

Dim AString As String * 1024

which provides for a 1k string. Obviously, you can use whatever declaration you like within the larger limits of Excel and available memory etc.

This may be a little inefficient in some cases, and you will probably wish to use Trim(AString) like constructs to obviate any superfluous trailing blanks. Still, it easily exceeds 256 chars.

I've done it like so:

((ViewManager)entry.getParent()).removeView(entry);

At first choose your API level from the following links:

API Level 17: http://dl-ssl.google.com/android/repository/docs-17_r02.zip

API Level 18: http://dl-ssl.google.com/android/repository/docs-18_r02.zip

API Level 19: http://dl-ssl.google.com/android/repository/docs-19_r02.zip

}

To me this happened due to a power failure while doing a git push.

The messages looked like this:

$ git status
error: object file .git/objects/c2/38824eb3fb602edc2c49fccb535f9e53951c74 is empty
error: object file .git/objects/c2/38824eb3fb602edc2c49fccb535f9e53951c74 is empty
fatal: loose object c238824eb3fb602edc2c49fccb535f9e53951c74 (stored in .git/objects/c2/38824eb3fb602edc2c49fccb535f9e53951c74) is corrupt

I tried things like git fsck but that didn't help. Since the crash happened during a git push, it obviously happened during rewrite on the client side which happens after the server is updated. I looked around and figured that c2388 in my case was a commit object, because it was referred to by entries in .git/refs. So I knew that I would be able to find c2388 when I look at the history (through a web interface or second clone).

On the second clone I did a git log -n 2 c2388 to identify the predecessor of c2388. Then I manually modified .git/refs/heads/master and .git/refs/remotes/origin/master to be the predecessor of c2388 instead of c2388. Then I could do a git fetch. The git fetch failed a few times for conflicts on empty objects. I removed each of these empty objects until git fetch succeeded. That has healed the repository.

- Another Update -

Since Twitter Bootstrap version 2.0 - which saw the removal of the .container-fluid class - it has not been possible to implement a two column fixed-fluid layout using just the bootstrap classes - however I have updated my answer to include some small CSS changes that can be made in your own CSS code that will make this possible

It is possible to implement a fixed-fluid structure using the CSS found below and slightly modified HTML code taken from the Twitter Bootstrap Scaffolding : layouts documentation page:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="fixed">  <!-- we want this div to be fixed width -->
            ...
        </div>
        <div class="hero-unit filler">  <!-- we have removed spanX class -->
            ...
        </div>
    </div>
</div>

CSS

/* CSS for fixed-fluid layout */

.fixed {
    width: 150px;  /* the fixed width required */
    float: left;
}

.fixed + div {
     margin-left: 150px;  /* must match the fixed width in the .fixed class */
     overflow: hidden;
}


/* CSS to ensure sidebar and content are same height (optional) */

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
    position: relative;
}

.filler:after{
    background-color:inherit;
    bottom: 0;
    content: "";
    height: auto;
    min-height: 100%;
    left: 0;
    margin:inherit;
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

I have kept the answer below - even though the edit to support 2.0 made it a fluid-fluid solution - as it explains the concepts behind making the sidebar and content the same height (a significant part of the askers question as identified in the comments)

Important

Answer below is fluid-fluid

Update As pointed out by @JasonCapriotti in the comments, the original answer to this question (created for v1.0) did not work in Bootstrap 2.0. For this reason, I have updated the answer to support Bootstrap 2.0

To ensure that the main content fills at least 100% of the screen height, we need to set the height of the html and body to 100% and create a new css class called .fill which has a minimum-height of 100%:

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
}

We can then add the .fill class to any element that we need to take up 100% of the sceen height. In this case we add it to the first div:

<div class="container-fluid fill">
    ...
</div>

To ensure that the Sidebar and the Content columns have the same height is very difficult and unnecessary. Instead we can use the ::after pseudo selector to add a filler element that will give the illusion that the two columns have the same height:

.filler::after {
    background-color: inherit;
    bottom: 0;
    content: "";
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

To make sure that the .filler element is positioned relatively to the .fill element we need to add position: relative to .fill:

.fill { 
    min-height: 100%;
    position: relative;
}

And finally add the .filler style to the HTML:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="span3">
            ...
        </div>
        <div class="span9 hero-unit filler">
            ...
        </div>
    </div>
</div>

Notes

• If you need the element on the left of the page to be the filler then you need to change right: 0 to left: 0.

You need to reference the namespace

using System.Windows.Form;

and then add in the code

protected void Button1_Click(object sender, EventArgs e)
    {
        MessageBox.Show(" Hi....");

    }

VBA stands for Visual Basic for Applications and so is the small "for applications" scripting brother of VB. VBA is indeed available in Excel, but also in the other office applications.

With VB, one can create a stand-alone windows application, which is not possible with VBA.

It is possible for developers however to "embed" VBA in their own applications, as a scripting language to automate those applications.

Edit: From the VBA FAQ:

Q. What is Visual Basic for Applications?

A. Microsoft Visual Basic for Applications (VBA) is an embeddable programming environment designed to enable developers to build custom solutions using the full power of Microsoft Visual Basic. Developers using applications that host VBA can automate and extend the application functionality, shortening the development cycle of custom business solutions.

Note that VB.NET is even another language, which only shares syntax with VB.

Unfortunately, git branch -a and git branch -r do not show you all remote branches, if you haven't executed a "git fetch".

git remote show origin works consistently all the time. Also git show-ref shows all references in the Git repository. However, it works just like the git branch command.

The JAVA_HOME should point to the JDK home rather than the JRE home if you are going to be compiling stuff, likewise - I would try and install the JDK in a directory that doesn't include a space. Even if this is not your problem now, it can cause problems in the future!

Have you tried this?

git log --pretty=oneline --abbrev-commit

The problem is probably that you are missing an empty line after the first line. The command above usually works for me, but I just tested on a commit without empty second line. I got the same result as you: the whole message on one line.

Empty second line is a standard in git commit messages. The behaviour you see was probably implemented on purpose.

The first line of a commit message is meant to be a short description. If you cannot make it in a single line you can use several, but git considers everything before the first empty line to be the "short description". oneline prints the whole short description, so all your 3 rows.

Depends on what you want to do:

to read the value as an ascii code, you can write

char a = 'a';
int ia = (int)a; 
/* note that the int cast is not necessary -- int ia = a would suffice */

to convert the character '0' -> 0, '1' -> 1, etc, you can write

char a = '4';
int ia = a - '0';
/* check here if ia is bounded by 0 and 9 */

a - '0' is equivalent to ((int)a) - ((int)'0'), which means the ascii values of the characters are subtracted from each other. Since 0 comes directly before 1 in the ascii table (and so on until 9), the difference between the two gives the number that the character a represents.

if your using react-slick you can try this on custom next and prev divs

Actually the orderBy filter can take as a parameter not only a string but also a function. From the orderBy documentation: https://docs.angularjs.org/api/ng/filter/orderBy):

function: Getter function. The result of this function will be sorted using the <, =, > operator.

So, you could write your own function. For example, if you would like to compare cards based on a sum of opt1 and opt2 (I'm making this up, the point is that you can have any arbitrary function) you would write in your controller:

$scope.myValueFunction = function(card) {
   return card.values.opt1 + card.values.opt2;
};

and then, in your template:

ng-repeat="card in cards | orderBy:myValueFunction"

Here is the working jsFiddle

The other thing worth noting is that orderBy is just one example of AngularJS filters so if you need a very specific ordering behaviour you could write your own filter (although orderBy should be enough for most uses cases).

You can't. You can only have one slide size and one orientation per presentation.

Are you projecting the presentation or delivering it on a laptop? If so, the size is sort of irrelevant.
Regardless of the slide size, the projected/displayed image will never be longer or wider than the projector/display accepts.

Based on @dfa's answer and another answer that shows how to test System.in, I would like to share my solution to give an input to a program and test its output.

As a reference, I use JUnit 4.12.

Let's say we have this program that simply replicates input to output:

import java.util.Scanner;

public class SimpleProgram {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print(scanner.next());
        scanner.close();
    }
}

To test it, we can use the following class:

import static org.junit.Assert.*;

import java.io.*;

import org.junit.*;

public class SimpleProgramTest {
    private final InputStream systemIn = System.in;
    private final PrintStream systemOut = System.out;

    private ByteArrayInputStream testIn;
    private ByteArrayOutputStream testOut;

    @Before
    public void setUpOutput() {
        testOut = new ByteArrayOutputStream();
        System.setOut(new PrintStream(testOut));
    }

    private void provideInput(String data) {
        testIn = new ByteArrayInputStream(data.getBytes());
        System.setIn(testIn);
    }

    private String getOutput() {
        return testOut.toString();
    }

    @After
    public void restoreSystemInputOutput() {
        System.setIn(systemIn);
        System.setOut(systemOut);
    }

    @Test
    public void testCase1() {
        final String testString = "Hello!";
        provideInput(testString);

        SimpleProgram.main(new String[0]);

        assertEquals(testString, getOutput());
    }
}

I won't explain much, because I believe the code is readable and I cited my sources.

When JUnit runs testCase1(), it is going to call the helper methods in the order they appear:

1. setUpOutput(), because of the @Before annotation
2. provideInput(String data), called from testCase1()
3. getOutput(), called from testCase1()
4. restoreSystemInputOutput(), because of the @After annotation

I didn't test System.err because I didn't need it, but it should be easy to implement, similar to testing System.out.

If you wants to sort on mulitple fields inside controller use this

$filter('orderBy')($scope.property_list, ['firstProp', 'secondProp']);

i ran the local mysql database, but not in administrator mode, which threw this error

It looks like you can simply do:

SELECT * FROM your_table WHERE some_column IS NULL OR some_column = '';

Test case:

CREATE TABLE your_table (id int, some_column varchar(10));

INSERT INTO your_table VALUES (1, NULL);
INSERT INTO your_table VALUES (2, '');
INSERT INTO your_table VALUES (3, 'test');
INSERT INTO your_table VALUES (4, 'another test');
INSERT INTO your_table VALUES (5, NULL);

Result:

SELECT id FROM your_table WHERE some_column IS NULL OR some_column = '';

id        
----------
1         
2         
5    

In kotlin, we can do the following. No need to iterate all the views. It will work for fragments also.

override fun dispatchTouchEvent(ev: MotionEvent?): Boolean {
    currentFocus?.let {
        val imm: InputMethodManager = getSystemService(
            Context.INPUT_METHOD_SERVICE
        ) as (InputMethodManager)
        imm.hideSoftInputFromWindow(it.windowToken, 0)
    }
    return super.dispatchTouchEvent(ev)
}

You can use viewtype to solve this problem, here is my demo: https://github.com/yefengfreedom/RecyclerViewWithHeaderFooterLoadingEmptyViewErrorView

1. you can define some recycler view display mode:

   public static final int MODE_DATA = 0, MODE_LOADING = 1, MODE_ERROR = 2, MODE_EMPTY = 3, MODE_HEADER_VIEW = 4, MODE_FOOTER_VIEW = 5;

2.override the getItemViewType mothod

 @Override
public int getItemViewType(int position) {
    if (mMode == RecyclerViewMode.MODE_LOADING) {
        return RecyclerViewMode.MODE_LOADING;
    }
    if (mMode == RecyclerViewMode.MODE_ERROR) {
        return RecyclerViewMode.MODE_ERROR;
    }
    if (mMode == RecyclerViewMode.MODE_EMPTY) {
        return RecyclerViewMode.MODE_EMPTY;
    }
    //check what type our position is, based on the assumption that the order is headers > items > footers
    if (position < mHeaders.size()) {
        return RecyclerViewMode.MODE_HEADER_VIEW;
    } else if (position >= mHeaders.size() + mData.size()) {
        return RecyclerViewMode.MODE_FOOTER_VIEW;
    }
    return RecyclerViewMode.MODE_DATA;
}

3.override the getItemCount method

@Override
public int getItemCount() {
    if (mMode == RecyclerViewMode.MODE_DATA) {
        return mData.size() + mHeaders.size() + mFooters.size();
    } else {
        return 1;
    }
}

4.override the onCreateViewHolder method. create view holder by viewType

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    if (viewType == RecyclerViewMode.MODE_LOADING) {
        RecyclerView.ViewHolder loadingViewHolder = onCreateLoadingViewHolder(parent);
        loadingViewHolder.itemView.setLayoutParams(
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, parent.getHeight() - mToolBarHeight)
        );
        return loadingViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_ERROR) {
        RecyclerView.ViewHolder errorViewHolder = onCreateErrorViewHolder(parent);
        errorViewHolder.itemView.setLayoutParams(
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, parent.getHeight() - mToolBarHeight)
        );
        errorViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnErrorViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnErrorViewClickListener.onErrorViewClick(v);
                        }
                    }, 200);
                }
            }
        });
        return errorViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_EMPTY) {
        RecyclerView.ViewHolder emptyViewHolder = onCreateEmptyViewHolder(parent);
        emptyViewHolder.itemView.setLayoutParams(
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, parent.getHeight() - mToolBarHeight)
        );
        emptyViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnEmptyViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnEmptyViewClickListener.onEmptyViewClick(v);
                        }
                    }, 200);
                }
            }
        });
        return emptyViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_HEADER_VIEW) {
        RecyclerView.ViewHolder headerViewHolder = onCreateHeaderViewHolder(parent);
        headerViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnHeaderViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnHeaderViewClickListener.onHeaderViewClick(v, v.getTag());
                        }
                    }, 200);
                }
            }
        });
        return headerViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_FOOTER_VIEW) {
        RecyclerView.ViewHolder footerViewHolder = onCreateFooterViewHolder(parent);
        footerViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnFooterViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnFooterViewClickListener.onFooterViewClick(v, v.getTag());
                        }
                    }, 200);
                }
            }
        });
        return footerViewHolder;
    }
    RecyclerView.ViewHolder dataViewHolder = onCreateDataViewHolder(parent);
    dataViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(final View v) {
            if (null != mOnItemClickListener) {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mOnItemClickListener.onItemClick(v, v.getTag());
                    }
                }, 200);
            }
        }
    });
    dataViewHolder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(final View v) {
            if (null != mOnItemLongClickListener) {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mOnItemLongClickListener.onItemLongClick(v, v.getTag());
                    }
                }, 200);
                return true;
            }
            return false;
        }
    });
    return dataViewHolder;
}

5.Override the onBindViewHolder method. bind data by viewType

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    if (mMode == RecyclerViewMode.MODE_LOADING) {
        onBindLoadingViewHolder(holder, position);
    } else if (mMode == RecyclerViewMode.MODE_ERROR) {
        onBindErrorViewHolder(holder, position);
    } else if (mMode == RecyclerViewMode.MODE_EMPTY) {
        onBindEmptyViewHolder(holder, position);
    } else {
        if (position < mHeaders.size()) {
            if (mHeaders.size() > 0) {
                onBindHeaderViewHolder(holder, position);
            }
        } else if (position >= mHeaders.size() + mData.size()) {
            if (mFooters.size() > 0) {
                onBindFooterViewHolder(holder, position - mHeaders.size() - mData.size());
            }
        } else {
            onBindDataViewHolder(holder, position - mHeaders.size());
        }
    }
}

Yes, if you don't mind the extra newlines being inserted:

 conn.exec 'select attr1, attr2, attr3, attr4, attr5, attr6, attr7
            from table1, table2, table3, etc, etc, etc, etc, etc,
            where etc etc etc etc etc etc etc etc etc etc etc etc etc'

Alternatively you can use a heredoc:

conn.exec <<-eos
   select attr1, attr2, attr3, attr4, attr5, attr6, attr7
   from table1, table2, table3, etc, etc, etc, etc, etc,
   where etc etc etc etc etc etc etc etc etc etc etc etc etc
eos

You should take a look the reference documentation. It's well explained.

In your case, I think you cannot use between because you need to pass two parameters

Between - findByStartDateBetween … where x.startDate between ?1 and ?2

In your case take a look to use a combination of LessThan or LessThanEqual with GreaterThan or GreaterThanEqual

• LessThan/LessThanEqual

LessThan - findByEndLessThan … where x.start< ?1

LessThanEqual findByEndLessThanEqual … where x.start <= ?1

• GreaterThan/GreaterThanEqual

GreaterThan - findByStartGreaterThan … where x.end> ?1

GreaterThanEqual - findByStartGreaterThanEqual … where x.end>= ?1

You can use the operator And and Or to combine both.

There are all kinds of wonderful ways to specify commits - see the specifying revisions section of man git-rev-parse for more details. In this case, you probably want:

git diff HEAD@{1}

The @{1} means "the previous position of the ref I've specified", so that evaluates to what you had checked out previously - just before the pull. You can tack HEAD on the end there if you also have some changes in your work tree and you don't want to see the diffs for them.

I'm not sure what you're asking for with "the commit ID of my latest version of the file" - the commit "ID" (SHA1 hash) is that 40-character hex right at the top of every entry in the output of git log. It's the hash for the entire commit, not for a given file. You don't really ever need more - if you want to diff just one file across the pull, do

git diff HEAD@{1} filename

This is a general thing - if you want to know about the state of a file in a given commit, you specify the commit and the file, not an ID/hash specific to the file.

@using (Html.BeginForm("DisplayPDF", "Scan", FormMethod.Post))
    {
        <a href="javascript:;" onclick="document.forms[0].submit();">View PDF</a>
    }

        {
            byte[] byteArray = GetPdfFromDB(4);
            MemoryStream pdfStream = new MemoryStream();
            pdfStream.Write(byteArray, 0, byteArray.Length);
            pdfStream.Position = 0;
            return new FileStreamResult(pdfStream, "application/pdf");
        }

        private byte[] GetPdfFromDB(int id)
        {
            #region
            byte[] bytes = { };

                {
                    cmd.CommandText = "SELECT Scan_Pdf_File FROM PWF_InvoiceMain WHERE InvoiceID=@Id and Enabled = 1";
                    cmd.Parameters.AddWithValue("@Id", id);
                    cmd.Connection = con;
                    con.Open();
                    using (SqlDataReader sdr = cmd.ExecuteReader())
                    {
                        if (sdr.HasRows == true)
                        {
                            sdr.Read();
                            bytes = (byte[])sdr["Scan_Pdf_File"];
                        }

            return bytes;
            #endregion
        }

@Column(name ="LEAD_ID")
private int leadId; 

Change to

@Column(name ="LEAD_ID")
private Integer leadId; 

Shouldn't creating a new Runnable class make a new second thread?

No. new Runnable does not create second Thread.

What is the purpose of the Runnable class here apart from being able to pass a Runnable class to postAtTime?

Runnable is posted to Handler. This task runs in the thread, which is associated with Handler.

If Handler is associated with UI Thread, Runnable runs in UI Thread.

If Handler is associated with other HandlerThread, Runnable runs in HandlerThread

To explicitly associate Handler to your MainThread ( UI Thread), write below code.

Handler  mHandler = new Handler(Looper.getMainLooper();

If you write is as below, it uses HandlerThread Looper.

HandlerThread handlerThread = new HandlerThread("HandlerThread");
handlerThread.start();
Handler requestHandler = new Handler(handlerThread.getLooper());

There are multiple solutions depending on the entity attribute type.

Basic attributes

Consider you have the following account table:

The account table is mapped to the Account entity like this:

@Entity(name = "Account")
public class Account {

    @Id
    private Long id;

    @ManyToOne
    private User owner;

    private String iban;

    private long cents;

    private double interestRate;

    private Timestamp createdOn;

    @Transient
    private double dollars;

    @Transient
    private long interestCents;

    @Transient
    private double interestDollars;

    @PostLoad
    private void postLoad() {
        this.dollars = cents / 100D;

        long months = createdOn.toLocalDateTime()
            .until(LocalDateTime.now(), ChronoUnit.MONTHS);
        double interestUnrounded = ( ( interestRate / 100D ) * cents * months ) / 12;
        this.interestCents = BigDecimal.valueOf(interestUnrounded)
            .setScale(0, BigDecimal.ROUND_HALF_EVEN).longValue();

        this.interestDollars = interestCents / 100D;
    }

    //Getters and setters omitted for brevity
}

The basic entity attributes are mapped to table columns, so properties like id, iban, cents are basic attributes.

But the dollars, interestCents, and interestDollars are computed properties, so you annotate them with @Transient to exclude them from SELECT, INSERT, UPDATE, and DELETE SQL statements.

So, for basic attributes, you need to use @Transient in order to exclude a given property from being persisted.

Associations

Assuming you have the following post and post_comment tables:

You want to map the latestComment association in the Post entity to the latest PostComment entity that was added.

To do that, you can use the @JoinFormula annotation:

@Entity(name = "Post")
@Table(name = "post")
public class Post {
 
    @Id
    private Long id;
 
    private String title;
 
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinFormula("(" +
        "SELECT pc.id " +
        "FROM post_comment pc " +
        "WHERE pc.post_id = id " +
        "ORDER BY pc.created_on DESC " +
        "LIMIT 1" +
    ")")
    private PostComment latestComment;
 
    //Getters and setters omitted for brevity
}

When fetching the Post entity, you can see that the latestComment is fetched, but if you want to modify it, the change is going to be ignored.

So, for associations, you can use @JoinFormula to ignore the write operations while still allowing reading the association.

@MapsId

Another way to ignore associations that are already mapped by the entity identifier is to use @MapsId.

For instance, consider the following one-to-one table relationship:

The PostDetails entity is mapped like this:

@Entity(name = "PostDetails")
@Table(name = "post_details")
public class PostDetails {
 
    @Id
    private Long id;
 
    @Column(name = "created_on")
    private Date createdOn;
 
    @Column(name = "created_by")
    private String createdBy;
 
    @OneToOne(fetch = FetchType.LAZY)
    @MapsId
    private Post post;
 
    public PostDetails() {}
 
    public PostDetails(String createdBy) {
        createdOn = new Date();
        this.createdBy = createdBy;
    }
 
    //Getters and setters omitted for brevity
}

Notice that both the id attribute and the post association map the same database column, which is the post_details Primary Key column.

To exclude the id attribute, the @MapsId annotation will tell Hibernate that the post association takes care of the table Primary Key column value.

So, when the entity identifier and an association share the same column, you can use @MapsId to ignore the entity identifier attribute and use the association instead.

Using insertable = false, updatable = false

Another option is to use insertable = false, updatable = false for the association which you want to be ignored by Hibernate.

For instance, we can map the previous one-to-one association like this:

@Entity(name = "PostDetails")
@Table(name = "post_details")
public class PostDetails {

    @Id
    @Column(name = "post_id")
    private Long id;

    @Column(name = "created_on")
    private Date createdOn;

    @Column(name = "created_by")
    private String createdBy;

    @OneToOne
    @JoinColumn(name = "post_id", insertable = false, updatable = false)
    private Post post;

    //Getters and setters omitted for brevity

    public void setPost(Post post) {
        this.post = post;
        if (post != null) {
            this.id = post.getId();
        }
    }
}

The insertable and updatable attributes of the @JoinColumn annotation will instruct Hibernate to ignore the post association since the entity identifier takes care of the post_id Primary Key column.

Place the following in your jQuery mouseover event handler:

$(this).css('color', 'red');

To set both color and size at the same time:

$(this).css({ 'color': 'red', 'font-size': '150%' });

You can set any CSS attribute using the .css() jQuery function.

Try to install it as a python package using pip. You said you already tried:

sudo apt-get install python-scipy

Now run:

pip install scipy

I ran both and it worked on my Debian-based box.

This is what I use often:

git fetch upstream develop;
git reset --hard upstream/develop;
git clean -d --force;

Note that it is good practice not to make changes to your local master/develop branch, but instead checkout to another branch for any change, with the branch name prepended by the type of change, e.g. feat/, chore/, fix/, etc. Thus you only need to pull changes, not push any changes from master. Same thing for other branches that others contribute to. So the above should only be used if you have happened to commit changes to a branch that others have committed to, and need to reset. Otherwise in future avoid pushing to a branch that others push to, instead checkout and push to the said branch via the checked out branch.

If you want to reset your local branch to the latest commit in the upstream branch, what works for me so far is:

Check your remotes, make sure your upstream and origin are what you expect, if not as expected then use git remote add upstream <insert URL>, e.g. of the original GitHub repo that you forked from, and/or git remote add origin <insert URL of the forked GitHub repo>.

git remote --verbose

git checkout develop;
git commit -m "Saving work.";
git branch saved-work;
git fetch upstream develop;
git reset --hard upstream/develop;
git clean -d --force

On GitHub, you can also checkout the branch with the same name as the local one, in order to save the work there, although this isn't necessary if origin develop has the same changes as the local saved-work branch. I'm using the develop branch as an example, but it can be any existing branch name.

git add .
git commit -m "Reset to upstream/develop"
git push --force origin develop

Then if you need to merge these changes with another branch while where there are any conflicts, preserving the changes in develop, use:

git merge -s recursive -X theirs develop

While use

git merge -s recursive -X ours develop

to preserve branch_name's conflicting changes. Otherwise use a mergetool with git mergetool.

With all the changes together:

git commit -m "Saving work.";
git branch saved-work;
git checkout develop;
git fetch upstream develop;
git reset --hard upstream/develop;
git clean -d --force;
git add .;
git commit -m "Reset to upstream/develop";
git push --force origin develop;
git checkout branch_name;
git merge develop;

Note that instead of upstream/develop you could use a commit hash, other branch name, etc. Use a CLI tool such as Oh My Zsh to check that your branch is green indicating that there is nothing to commit and the working directory is clean (which is confirmed or also verifiable by git status). Note that this may actually add commits compared to upstream develop if there is anything automatically added by a commit, e.g. UML diagrams, license headers, etc., so in that case, you could then pull the changes on origin develop to upstream develop, if needed.

You can use the subprocess package with the code as below:

import subprocess
cmdCommand = "python test.py"   #specify your cmd command
process = subprocess.Popen(cmdCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
print output

Copy multiple files from remote to local:

$ scp [email protected]:/some/remote/directory/\{a,b,c\} ./

Copy multiple files from local to remote:

$ scp foo.txt bar.txt [email protected]:~
$ scp {foo,bar}.txt [email protected]:~
$ scp *.txt [email protected]:~

Copy multiple files from remote to remote:

$ scp [email protected]:/some/remote/directory/foobar.txt \
[email protected]:/some/remote/directory/

Using numpy, you can define the following:

import numpy as np

def cart2pol(x, y):
    rho = np.sqrt(x**2 + y**2)
    phi = np.arctan2(y, x)
    return(rho, phi)

def pol2cart(rho, phi):
    x = rho * np.cos(phi)
    y = rho * np.sin(phi)
    return(x, y)

This may help some people who still have problems. I use Visual Studio 2015 and I could only pass the arguments when I changed the definition of argv.

Instead of

int main(int argc, char **argv){
}

I had to use

int main(int argc, char *argv[]){
}

I do not know why it was necessary, but it works.

kramdown—the Ruby-based markdown engine that is the default for Jekyll and thus GitHub Pages—has built-in comment support through its extension syntax:

{::comment}
This text is completely ignored by kramdown - a comment in the text.
{:/comment}

Do you see {::comment}this text{:/comment}?
{::comment}some other comment{:/}

This has the benefit of allowing in-line comments, but the downside of not being portable to other Markdown engines.

This shows the number of connections per each DB:

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NumberOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
GROUP BY 
    dbid, loginame

And this gives the total:

SELECT 
    COUNT(dbid) as TotalConnections
FROM
    sys.sysprocesses
WHERE 
    dbid > 0

If you need more detail, run:

sp_who2 'Active'

Note: The SQL Server account used needs the 'sysadmin' role (otherwise it will just show a single row and a count of 1 as the result)

Another solution is to install Xvfb, and export your display to it. ie:

disp=:8
screen=0
geom=640x480x24
exec Xvfb $disp -screen $screen $geom 2>/tmp/Xvfb.log &

Then

$ export DISPLAY=:8

$ ./example.py

I had this problem and if you actually never played with your server configuration settings, then your problem is 90% in your .htaccess file

You either modify .htaccess file LOCALLY, ore delete it (LOCALLY)

n=int(raw_input("Enter no. of terms:"))

L=[]

for i in range (1,n+1):

    x=float(raw_input("Enter term:"))

    L.append(x)

sum=0

for i in range(n):

    sum=sum+L[i]

avg=sum/n

sumdev=0

for j in range(n):

    sumdev=sumdev+(L[j]-avg)**2

dev=(sumdev/n)**0.5

print "Standard deviation is", dev

If you wish to allow accent (see RFC 5322) and allow new domain extension like .quebec. use this expression:

/\b[a-zA-Z0-9\u00C0-\u017F._%+-]+@[a-zA-Z0-9\u00C0-\u017F.-]+\.[a-zA-Z]{2,}\b/

• The '\u00C0-\u017F' part is for alowing accent. We use the unicode range for that.
• The '{2,}' simply say a minimum of 2 char for the domain extension. You can replace this by '{2,63}' if you dont like the infinitive range.

I think you're using the best method, though you could optimize it to:

 $("<div/>");

<script>
    $('#btn_hide').click( function () {
      $('#btn_hide').hide();
    });
</script>
<input type="button" id="btn_hide"/>

this will be enough

Quite often this means that the listener hasn't started. Check the Services panel.

On Windows (as you are) another common cause is that the ORACLE_SID is not defined in the registry. Either edit the registry or set the ORACLE_SID in a CMD box. (Because you want to run sqlplusw.exe I suggest you edit the registry.)

You can try this:

SELECT TO_CHAR(dbms_lob.substr(BLOB_FIELD, 3900)) FROM TABLE_WITH_BLOB;

However, It would be limited to 4000 byte

The parameters of isset() should be separated by a comma sign (,) and not a dot sign (.). Your current code concatenates the variables into a single parameter, instead of passing them as separate parameters.

So the original code evaluates the variables as a unified string value:

isset($_POST['search_term'] . $_POST['postcode']) // Incorrect

While the correct form evaluates them separately as variables:

isset($_POST['search_term'], $_POST['postcode']) // Correct

In Java 8, this is possible in a single line of code as follows:

int sum = Pattern.compile("")
        .splitAsStream(factorialNumber.toString())
        .mapToInt(Integer::valueOf)
        .sum();

I looked everywhere for an answer and finally this worked for me:

SELECT Lower(Substring(MASTER.dbo.Fn_varbintohexstr(0x21232F297A57A5A743894A0E4A801FC3), 3, 8000))

Outputs to (string):

21232f297a57a5a743894a0e4a801fc3

You can use it in your WHERE or JOIN conditions as well in case you want to compare/match varbinary records with strings
