You need to use brackets when using the fileExists step in an if condition or assign the returned value to a variable

Using variable:

def exists = fileExists 'file'

if (exists) {
    echo 'Yes'
} else {
    echo 'No'
}

Using brackets:

if (fileExists('file')) {
    echo 'Yes'
} else {
    echo 'No'
}

I tried Noah's suggestion which leads to the best solution up to now.

Just insert \let\cleardoublepage\clearpage before all the parts with the blank pages Especially when you use \documentclass[12pt,a4paper]{book}

frederic snyers's advice \documentclass[oneside]{book} is also very good and solves the problem, but if we just want to use the book.cls or article.cls, the one would make a big difference presenting your particles.

Hence, Big support to \let\cleardoublepage\clearpage for the people who will ask the same question in the future.

What you want to do is -

strtemp = ";".join(l)

The first line adds a ; to the end of MySpace so that while splitting, it does not give out MySpaceApple This will join l into one string and then you can just-

l1 = strtemp.split(";")

This works because strtemp is a string which has .split()

The "break" command does not work within an "if" statement.

If you remove the "break" command from your code and then test the code, you should find that the code works exactly the same without a "break" command as with one.

"Break" is designed for use inside loops (for, while, do-while, enhanced for and switch).

Currently i'm using the below method. Works with no issues.

* * * * * /bin/bash -c ' for i in {1..X}; do YOUR_COMMANDS ; sleep Y ; done '

If you want to run every N seconds then X will be 60/N and Y will be N.

Use patchValue() method which helps to update even subset of controls.

setValue(){
  this.editqueForm.patchValue({user: this.question.user, questioning: this.question.questioning})
}

Error When strict checks fail, such as setting the value of a control that doesn't exist or if you excluding the value of a control.

In your case, object missing options and questionType control value so setValue() will fail to update.

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

Swift version:

var myView = UIView(frame: CGRect(x: 100, y: 100, width: 100, height: 100))
myView.backgroundColor = UIColor.yellowColor() 

var border = CALayer()
border.backgroundColor = UIColor.lightGrayColor()
border.frame = CGRect(x: 0, y: 0, width: myView.frame.width, height: 0.5)

myView.layer.addSublayer(border)

Edit: For updated versions check my repo here: https://github.com/goktugyil/EZSwiftExtensions/blob/master/Sources/UIViewExtensions.swift

Look at the addBorder parts

There are already a lot of answers in this thread but none of them particularly helped me, I had to work it out myself, so I hope this one is a little more informative.

You just have to make sure you have parentheses at the end of your class, e.g:

print(class())

Here's an example of code from a project I was working on:

class Element:
    def __init__(self, name, symbol, number):
        self.name = name
        self.symbol = symbol
        self.number = number
    def __str__(self):
        return "{}: {}\nAtomic Number: {}\n".format(self.name, self.symbol, self.number

class Hydrogen(Element):
    def __init__(self):
        super().__init__(name = "Hydrogen", symbol = "H", number = "1")

To print my Hydrogen class, I used the following:

print(Hydrogen())

Please note, this will not work without the parentheses at the end of Hydrogen. They are necessary.

Hope this helps, let me know if you have anymore questions.

The easiest way to do that would be to use the Params plugin, introduced in beta5. It has utility methods to make it easy to access different types of parameters. As always, reading the tests can prove valuable to understand how something is supposed to be used.

Get a single value

To get the value of a named parameter in a controller, you will need to select the appropriate method for the type of parameter you are looking for and pass in the name.

Examples:

$this->params()->fromPost('paramname');   // From POST
$this->params()->fromQuery('paramname');  // From GET
$this->params()->fromRoute('paramname');  // From RouteMatch
$this->params()->fromHeader('paramname'); // From header
$this->params()->fromFiles('paramname');  // From file being uploaded

Default values

All of these methods also support default values that will be returned if no parameter with the given name is found.

Example:

$orderBy = $this->params()->fromQuery('orderby', 'name');

When visiting http://example.com/?orderby=birthdate, $orderBy will have the value birthdate.
When visiting http://example.com/, $orderBy will have the default value name.
 

Get all parameters

To get all parameters of one type, just don't pass in anything and the Params plugin will return an array of values with their names as keys.

Example:

$allGetValues = $this->params()->fromQuery(); // empty method call

When visiting http://example.com/?orderby=birthdate&filter=hasphone $allGetValues will be an array like

array(
    'orderby' => 'birthdate',
    'filter'  => 'hasphone',
);

Not using Params plugin

If you check the source code for the Params plugin, you will see that it's just a thin wrapper around other controllers to allow for more consistent parameter retrieval. If you for some reason want/need to access them directly, you can see in the source code how it's done.

Example:

$this->getRequest()->getRequest('name', 'default');
$this->getEvent()->getRouteMatch()->getParam('name', 'default');

NOTE: You could have used the superglobals $_GET, $_POST etc., but that is discouraged.

Ordinary javascript cannot close windows willy-nilly. This is a security feature, introduced a while ago, to stop various malicious exploits and annoyances.

From the latest working spec for window.close():

The close() method on Window objects should, if all the following conditions are met, close the browsing context A:

• The corresponding browsing context A is script-closable.
• The browsing context of the incumbent script is familiar with the browsing context A.
• The browsing context of the incumbent script is allowed to navigate the browsing context A.

A browsing context is script-closable if it is an auxiliary browsing context that was created by a script (as opposed to by an action of the user), or if it is a browsing context whose session history contains only one Document.

This means, with one small exception, javascript must not be allowed to close a window that was not opened by that same javascript.

Chrome allows that exception -- which it doesn't apply to userscripts -- however Firefox does not. The Firefox implementation flat out states:

This method is only allowed to be called for windows that were opened by a script using the window.open method.

If you try to use window.close from a Greasemonkey / Tampermonkey / userscript you will get:
Firefox: The error message, "Scripts may not close windows that were not opened by script."
Chrome: just silently fails.

The long-term solution:

The best way to deal with this is to make a Chrome extension and/or Firefox add-on instead. These can reliably close the current window.

However, since the security risks, posed by window.close, are much less for a Greasemonkey/Tampermonkey script; Greasemonkey and Tampermonkey could reasonably provide this functionality in their API (essentially packaging the extension work for you).
Consider making a feature request.

The hacky workarounds:

Chrome is currently was vulnerable to the "self redirection" exploit. So code like this used to work in general:

open(location, '_self').close();

This is buggy behavior, IMO, and is now (as of roughly April 2015) mostly blocked. It will still work from injected code only if the tab is freshly opened and has no pages in the browsing history. So it's only useful in a very small set of circumstances.

However, a variation still works on Chrome (v43 & v44) plus Tampermonkey (v3.11 or later). Use an explicit @grant and plain window.close(). EG:

// ==UserScript==
// @name        window.close demo
// @include     http://YOUR_SERVER.COM/YOUR_PATH/*
// @grant       GM_addStyle
// ==/UserScript==

setTimeout (window.close, 5000);

Thanks to zanetu for the update. Note that this will not work if there is only one tab open. It only closes additional tabs.

Firefox is secure against that exploit. So, the only javascript way is to cripple the security settings, one browser at a time.

You can open up about:config and set
allow_scripts_to_close_windows to true.

If your script is for personal use, go ahead and do that. If you ask anyone else to turn that setting on, they would be smart, and justified, to decline with prejudice.

There currently is no equivalent setting for Chrome.

You can use your favourite telnet (not recommended) or ssh (recommended) application to connect to your Synology box and use it as a terminal.

1. Enable the command line interface (CLI) from the Network Services
2. Define the protocol and the user and make sure the user has password set
3. Access the CLI

If you need more detailed instruction read https://www.synology.com/en-global/knowledgebase/DSM/help/DSM/AdminCenter/system_terminal

The & makes the command run in the background.

From man bash:

If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0.

You can do the following:

df =DataFrame({'a':[1,2,3,4],'b':[2,4,6,8]})

df['x']=df.a + df.b
df['y']=df.a - df.b

create column title whatever order you want in this way:

column_titles = ['x','y','a','b']

df.reindex(columns=column_titles)

This will give you desired output

This post contains 2 examples. I like the 2nd one:

  Dim i As Long 
 
  aFirstArray() = Array("Banana", "Apple", "Orange", "Tomato", "Apple", _ 
  "Lemon", "Lime", "Lime", "Apple") 
 
  On Error Resume Next 
  For Each a In aFirstArray 
     arr.Add a, a 
  Next
  On Error Goto 0 ' added to original example by PEH
 
  For i = 1 To arr.Count 
     Cells(i, 1) = arr(i) 
  Next 
 
End Sub 

From the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc.

Thus, if you want to get the same behavior for both login shells and interactive non-login shells, you should put all of your commands in either .bashrc or .bash_profile, and then have the other file source the first one.

Below JS function you can use to filter the row based on some specified columns see searchColumn array. It is taken from w3 school and little bit customised to search and filter on the given list of column.

$('selector').css('cursor', 'pointer'); // 'default' to revert

I know that may be confusing per your original question, but the "finger" cursor is actually called "pointer".

The normal arrow cursor is just "default".

all possible default pointer looks DEMO

Try:

ArrayListname.get(index);

Where index is the position in the index and ArrayListname is the name of the Arraylist as in your case is mainList.

I had this but unlike the OP I couldn't see any output before the TCPDF error message.

Turns out there was a UTF8 BOM (byte-order-mark) at the very start of my script, before the <?php tag so before I had any chance to call ob_start(). And there was also a UTF8 BOM before the TCPDF error message.

I think you need something like:

var text= data.response.venue.tips.groups[0].items[1].text;

You need to give the array a size:

public static void main(String args[])
{
    int array[] = new int[4];
    int number = 5, i = 0,j = 0;
    while (i<4){
        array[i]=number;
        i=i+1;
    }
    while (j<4){
        System.out.println(array[j]);
        j++;
    }
}

The other answers are correct but you can omit the [attr.data-index] altogether and just use

<ul>
    <li *ngFor="let item of items; let i = index">{{i + 1}}</li>
</ul

@Furqan Could you please let me know whether you tested this with HTTP POST method,

Since I am also working on the same kind of situation, but I am not able to POST the data to different domain.

But after reading this it was quite simple...only thing is you have to forget about OLD browsers. I am giving code to send with POST method from same above URL for quick reference

function createCORSRequest(method, url){
var xhr = new XMLHttpRequest();
if ("withCredentials" in xhr){
    xhr.open(method, url, true);
} else if (typeof XDomainRequest != "undefined"){
    xhr = new XDomainRequest();
    xhr.open(method, url);
} else {
    xhr = null;
}
return xhr;
}

var request = createCORSRequest("POST", "http://www.sanshark.com/");
var content = "name=sandesh&lastname=daddi";
if (request){
    request.onload = function(){
    //do something with request.responseText
   alert(request.responseText);
};

 request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
            request.setRequestHeader("Content-length", content.length);
            request.send(content);
}

You really want to do this

flog.write("\nCompany Name: "+ pCompanyName.encode('utf-8'))

This is the "encode late" strategy described in this unicode presentation (slides 32 through 35).

In the below example, I have stored the Makefile folder path to LOCAL_PKG_DIR and then use LOCAL_PKG_DIR variable in targets.

We have plenty of options to validate the react js forms. Maybe the npm packages have some own limitations. Based up on your needs you can choose the right validator packages. I would like to recommend some, those are listed below.

• react-form-input-validation
• redux-form

If anybody knows a better solution than this, please put it on the comment section for other people references.

Passing the dataframes to concat in a dictionary, results in a multi-index dataframe from which you can easily delete the duplicates, which results in a multi-index dataframe with the differences between the dataframes:

import sys
if sys.version_info[0] < 3:
    from StringIO import StringIO
else:
    from io import StringIO
import pandas as pd

DF1 = StringIO("""Date       Fruit  Num  Color 
2013-11-24 Banana 22.1 Yellow
2013-11-24 Orange  8.6 Orange
2013-11-24 Apple   7.6 Green
2013-11-24 Celery 10.2 Green
""")
DF2 = StringIO("""Date       Fruit  Num  Color 
2013-11-24 Banana 22.1 Yellow
2013-11-24 Orange  8.6 Orange
2013-11-24 Apple   7.6 Green
2013-11-24 Celery 10.2 Green
2013-11-25 Apple  22.1 Red

df1 = pd.read_table(DF1, sep='\s+')
df2 = pd.read_table(DF2, sep='\s+')
#%%
dfs_dictionary = {'DF1':df1,'DF2':df2}
df=pd.concat(dfs_dictionary)
df.drop_duplicates(keep=False)

Result:

I think the ONLamp introduction to metaclass programming is well written and gives a really good introduction to the topic despite being several years old already.

http://www.onlamp.com/pub/a/python/2003/04/17/metaclasses.html (archived at https://web.archive.org/web/20080206005253/http://www.onlamp.com/pub/a/python/2003/04/17/metaclasses.html)

In short: A class is a blueprint for the creation of an instance, a metaclass is a blueprint for the creation of a class. It can be easily seen that in Python classes need to be first-class objects too to enable this behavior.

I've never written one myself, but I think one of the nicest uses of metaclasses can be seen in the Django framework. The model classes use a metaclass approach to enable a declarative style of writing new models or form classes. While the metaclass is creating the class, all members get the possibility to customize the class itself.

• Creating a new model
• The metaclass enabling this

The thing that's left to say is: If you don't know what metaclasses are, the probability that you will not need them is 99%.

I tried {CultureInfo currentCulture = Thread.CurrentThread.CurrentCulture;} but it didn`t work for me, since my UI culture was different from my number/currency culture. So I suggest you to use:

CultureInfo currentCulture = Thread.CurrentThread.CurrentUICulture;

This will give you the culture your UI is (texts on windows, message boxes, etc).

I found the answer to the second part of my questions. Yes, a class can implement an interface that is in a different class as long that the interface is declared as public.

As pointed out (and hopefully unsurprisingly), using if+else is indeed the idiomatic way to do conditionals in Go.

In addition to the full blown var+if+else block of code, though, this spelling is also used often:

index := val
if val <= 0 {
    index = -val
}

and if you have a block of code that is repetitive enough, such as the equivalent of int value = a <= b ? a : b, you can create a function to hold it:

func min(a, b int) int {
    if a <= b {
        return a
    }
    return b
}

...

value := min(a, b)

The compiler will inline such simple functions, so it's fast, more clear, and shorter.

You must take the whole directory where java is installed, in my case:

export JAVA_HOME=/usr/java/jdk1.8.0_31

Change

dateTime.setText(app.getTotalDl());

To

dateTime.setText(String.valueOf(app.getTotalDl()));

There are different versions of setText - one takes a String and one takes an int resource id. If you pass it an integer it will try to look for the corresponding string resource id - which it can't find, which is your error.

I guess app.getTotalDl() returns an int. You need to specifically tell setText to set it to the String value of this int.

setText (int resid) vs setText (CharSequence text)

I would like to update the existing solution to help the people who are going to calculate the semantic similarity of sentences.

Step 1:

Load the suitable model using gensim and calculate the word vectors for words in the sentence and store them as a word list

Step 2 : Computing the sentence vector

The calculation of semantic similarity between sentences was difficult before but recently a paper named "A SIMPLE BUT TOUGH-TO-BEAT BASELINE FOR SENTENCE EMBEDDINGS" was proposed which suggests a simple approach by computing the weighted average of word vectors in the sentence and then remove the projections of the average vectors on their first principal component.Here the weight of a word w is a/(a + p(w)) with a being a parameter and p(w) the (estimated) word frequency called smooth inverse frequency.this method performing significantly better.

A simple code to calculate the sentence vector using SIF(smooth inverse frequency) the method proposed in the paper has been given here

Step 3: using sklearn cosine_similarity load two vectors for the sentences and compute the similarity.

This is the most simple and efficient method to compute the sentence similarity.

Take a look at the Tiny But Strong templating system. It's generally used for templating HTML but there's an extension that works with XML files. I use this extensively for creating reports where I can have one code file and two template files - htm and xml - and the user can then choose whether to send a report to screen or spreadsheet.

Another advantage is you don't have to code the xml from scratch, in some cases I've been wanting to export very large complex spreadsheets, and instead of having to code all the export all that is required is to save an existing spreadsheet in xml and substitute in code tags where data output is required. It's a quick and a very efficient way to work.

This worked for me:

var xdoc = new XmlDocument { XmlResolver = null };  
xdoc.LoadXml(xmlFragment);

Try using the Dictionary Object or the Collection Object.

http://visualbasic.ittoolbox.com/documents/dictionary-object-vs-collection-object-12196

match returns an array.

The default string representation of an array in JavaScript is the elements of the array separated by commas. In this case the desired result is in the second element of the array:

var tesst = "afskfsd33j"
var test = tesst.match(/a(.*)j/);
alert (test[1]);

The ToString method of any object is supposed to return a string representation of that object.

int var1 = 2;

string var2 = var1.ToString();

You need to call .validate() before you can add rules this way, like this:

$("#myForm").validate(); //sets up the validator
$("input[id*=Hours]").rules("add", "required");

The .validate() documentation is a good guide, here's the blurb about .rules("add", option):

Adds the specified rules and returns all rules for the first matched element. Requires that the parent form is validated, that is, $("form").validate() is called first.

assuming you have a SQL table called mydata - you can load data from a csv file as follows:

COPY MYDATA FROM '<PATH>/MYDATA.CSV' CSV HEADER;

For more details refer to: http://www.postgresql.org/docs/9.2/static/sql-copy.html

I just tried using all the ideas on this page and I didn't like any of them. I just wanted a solution that started tmux with a specific set of windows when my terminal opened. I also wanted it to be idempotent, i.e. opening a new terminal window takes over the tmux session from the previous one.

The above solutions often tend to open multiple tmux sessions and I want just one. First, I added this to my ~/.bash_profile:

tmux start-server
if [[ -z "$TMUX" ]]
then
  exec tmux attach -d -t default
fi

then I added the following to my ~/.tmux.conf:

new -s default -n emacs /usr/local/bin/emacs
neww -n shell /usr/local/bin/bash
neww -n shell /usr/local/bin/bash
selectw -t 1

now every time I start a terminal or start tmux or whatever, I either reattach to my existing desired setup (the session named default), or create a new session with that setup.

If you are in an environment of ECMAScript 6, using the Spread Operator you could do it this way:

var arr1 = ['a','b','c'];_x000D_
var arr2 = [...arr1]; //copy arr1_x000D_
arr2.push('d');_x000D_
_x000D_
console.log(arr1)_x000D_

Using dialog methods:

$('.selectorUsedToCreateTheDialog').dialog('option', 'title', 'My New title');

Or directly, hacky though:

$("span.ui-dialog-title").text('My New Title');

Make sure that when you cloned the repository, you did so with the SSH URL and not the HTTPS; in the clone URL box of the repo, choose the SSH protocol before copying the URL. See image below:

Write the Date = document.write(Date());

You can use some functional programming approach, transforming data:

['12','34','35','231'].map{|i| "'#{i}'"}.join(",")

As others have submitted quadratic worst-case time complexity solution, I'd add a linear one (based on the KMP Algorithm):

bool is_rotation(const string& str1, const string& str2)
{
  if(str1.size()!=str2.size())
    return false;

  vector<size_t> prefixes(str1.size(), 0);
  for(size_t i=1, j=0; i<str1.size(); i++) {
    while(j>0 && str1[i]!=str1[j])
      j=prefixes[j-1];
    if(str1[i]==str1[j]) j++;
    prefixes[i]=j;
  }

  size_t i=0, j=0;
  for(; i<str2.size(); i++) {
    while(j>0 && str2[i]!=str1[j])
      j=prefixes[j-1];
    if(str2[i]==str1[j]) j++;
  }
  for(i=0; i<str2.size(); i++) {
    if(j>=str1.size()) return true;
    while(j>0 && str2[i]!=str1[j])
      j=prefixes[j-1];
    if(str2[i]==str1[j]) j++;
  }

  return false;
}

In C# 7.1 you will be able to do a proper async Main. The appropriate signatures for Main method has been extended to:

public static Task Main();
public static Task<int> Main();
public static Task Main(string[] args);
public static Task<int> Main(string[] args);

For e.g. you could be doing:

static async Task Main(string[] args)
{
    Bootstrapper bs = new Bootstrapper();
    var list = await bs.GetList();
}

At compile time, the async entry point method will be translated to call GetAwaitor().GetResult().

Details: https://blogs.msdn.microsoft.com/mazhou/2017/05/30/c-7-series-part-2-async-main

EDIT:

To enable C# 7.1 language features, you need to right-click on the project and click "Properties" then go to the "Build" tab. There, click the advanced button at the bottom:

From the language version drop-down menu, select "7.1" (or any higher value):

The default is "latest major version" which would evaluate (at the time of this writing) to C# 7.0, which does not support async main in console apps.

I know it's an old post but what about this solution (I've made a JSFiddle to illustrate it)... Solution that uses the :after pseudo elements of <span> to show/hide the <span> switch link itself (in addition to the .alert message it must show/hide). When the pseudo element loses it's focus, the message is hidden.

The initial situation is a hidden message that appears when the <span> with the :after content : "Show Me"; is focused. When this <span> is focused, it's :after content becomes empty while the :after content of the second <span> (that was initially empty) turns to "Hide Me". So, when you click this second <span> the first one loses it's focus and the situation comes back to it's initial state.

I started on the solution offered by @Vector I kept the DOM'situation presented ky @Frederic Kizar

HTML:

<span class="span3" tabindex="0"></span>
<span class="span2" tabindex="0"></span>
<p class="alert" >Some message to show here</p>

CSS:

body {
    display: inline-block;
}
.span3 ~ .span2:after{
    content:"";
}
.span3:focus ~ .alert  {
    display:block;
}
.span3:focus ~ .span2:after  {
    content:"Hide Me";
}
.span3:after  {
    content: "Show Me";
}
.span3:focus:after  {
    content: "";
}
.alert  {
    display:none;
}

After you install the missing zlib dev package you can also use pythonbrew to uninstall and then reinstall the version of python you wanted and it seems like it picks up the new package to compile to correct abilities. This way you can keep using pythonbrew and don't have to do the compilation yourself (though it isn't that difficult)

Try this:

var setCanvasSize = function() {
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;

I solved this problem on Github separating the indented sub-block with a newline, for instance, you write the item 1, then hit enter twice (like if it was a new paragraph), indent the block and write what you want (a block of code, text, etc). More information on Markdown lists and Markdown line breaks.

Example:

1. item one

2. item two

   this block acts as a new paragraph, above there is a blank line

3. item three

   some other code

4. item four

Google Apps Script is JavaScript, the date object is initiated with new Date() and all JavaScript methods apply, see doc here

There is no built-in operator to do it in Go. You need to iterate over the array. You can write your own function to do it, like this:

func stringInSlice(a string, list []string) bool {
    for _, b := range list {
        if b == a {
            return true
        }
    }
    return false
}

If you want to be able to check for membership without iterating over the whole list, you need to use a map instead of an array or slice, like this:

visitedURL := map[string]bool {
    "http://www.google.com": true,
    "https://paypal.com": true,
}
if visitedURL[thisSite] {
    fmt.Println("Already been here.")
}

If you want to detach existing object follow @Slauma's advice. If you want to load objects without tracking changes use:

var data = context.MyEntities.AsNoTracking().Where(...).ToList();

As mentioned in comment this will not completely detach entities. They are still attached and lazy loading works but entities are not tracked. This should be used for example if you want to load entity only to read data and you don't plan to modify them.

I just had the same problem and...

declare @userId uniqueidentifier
set @userId = (select top 1 UserId from aspnet_Users)

or even shorter:

declare @userId uniqueidentifier
SELECT TOP 1 @userId = UserId FROM aspnet_Users

1. Anything but ECB.
2. If using CTR, it is imperative that you use a different IV for each message, otherwise you end up with the attacker being able to take two ciphertexts and deriving a combined unencrypted plaintext. The reason is that CTR mode essentially turns a block cipher into a stream cipher, and the first rule of stream ciphers is to never use the same Key+IV twice.
3. There really isn't much difference in how difficult the modes are to implement. Some modes only require the block cipher to operate in the encrypting direction. However, most block ciphers, including AES, don't take much more code to implement decryption.
4. For all cipher modes, it is important to use different IVs for each message if your messages could be identical in the first several bytes, and you don't want an attacker knowing this.

You can't get value when calling getJSON, only after response.

var myjson;
$.getJSON("http://127.0.0.1:8080/horizon-update", function(json){
    myjson = json;
});

It's quite simple. (Adapt syntax for your convenience)

public $smtp = array(
    'transport' => 'Smtp',
    'from' => '[email protected]',
    'host' => 'ssl://smtp.gmail.com',
    'port' => 465,
    'timeout' => 30,
    'username' => '[email protected]',
    'password' => '*****'
)

function parseMinutes(x) {
  hours = Math.floor(x / 60);
  minutes = x % 60;
}

function parseHours(H, M) {
  x = M + H * 60;
}

JUST copy and paste tnsnames and sqlnet files from Oracle home in PLSQL Developer Main folder. Use below Query to get oracle home

select substr(file_spec, 1, instr(file_spec, '\', -1, 2) -1) ORACLE_HOME from dba_libraries where library_name = 'DBMS_SUMADV_LIB';

Altenative one-liners in plain-old java:

String.format("The date: %tY-%tm-%td", date, date, date);

String.format("The date: %1$tY-%1$tm-%1$td", date);

String.format("Time with tz: %tY-%<tm-%<td %<tH:%<tM:%<tS.%<tL%<tz", date);

String.format("The date and time in ISO format: %tF %<tT", date);

This uses Formatter and relative indexing instead of SimpleDateFormat which is not thread-safe, btw.

Slightly more repetitive but needs just one statement. This may be handy in some cases.

Add the active: false option (documentation)..

There are Registry changes you can make to explicitly select where the crash dump file resides, otherwise %localappdata%\Microsoft\Windows\WER is the default location. I assume that %localappdata% is defined differently for a user or a service running under System. You will need to enable WER I believe.

You should use this code

this.setVisible(false); //this will close frame i.e. NewJFrame

new NewJFrame().setVisible(true); // Now this will open NewJFrame for you again and will also get refreshed 

There are many ways to skip the first line. In addition to those said by Bakuriu, I would add:

with open(filename, 'r') as f:
    next(f)
    for line in f:

and:

with open(filename,'r') as f:
    lines = f.readlines()[1:]

You could store key/values in Redis differently to achieve this, by just adding a prefix or namespace to your keys when you store them e.g. "hset_"

• Get a key/value GET hset_key equals to HGET hset key

• Add a key/value SET hset_key value equals to HSET hset key

• Get all keys KEYS hset_* equals to HGETALL hset

• Get all vals should be done in 2 ops, first get all keys KEYS hset_* then get the value for each key

• Add a key/value with TTL or expire which is the topic of question:

 SET hset_key value
 EXPIRE hset_key

Note: KEYS will lookup up for matching the key in the whole database which may affect on performance especially if you have big database.

Note:

• KEYS will lookup up for matching the key in the whole database which may affect on performance especially if you have big database. while SCAN 0 MATCH hset_* might be better as long as it doesn't block the server but still performance is an issue in case of big database.

• You may create a new database for storing separately these keys that you want to expire especially if they are small set of keys.

Thanks to @DanFarrell who highlighted the performance issue related to KEYS

Here's a modified perl script based on a few of the other answers:

perl -pe 's/([^\\]|^)\$\{([a-zA-Z_][a-zA-Z_0-9]*)\}/$1.$ENV{$2}/eg' -i template

Features (based on my needs, but should be easy to modify):

• Skips escaped parameter expansions (e.g. \${VAR}).
• Supports parameter expansions of the form ${VAR}, but not $VAR.
• Replaces ${VAR} with a blank string if there is no VAR envar.
• Only supports a-z, A-Z, 0-9 and underscore characters in the name (excluding digits in the first position).

RexExp instances have a lastIndex property already (if they are global) and so what I'm doing is copying the regular expression, modifying it slightly to suit our purposes, exec-ing it on the string and looking at the lastIndex. This will inevitably be faster than looping on the string. (You have enough examples of how to put this onto the string prototype, right?)

function reIndexOf(reIn, str, startIndex) {
    var re = new RegExp(reIn.source, 'g' + (reIn.ignoreCase ? 'i' : '') + (reIn.multiLine ? 'm' : ''));
    re.lastIndex = startIndex || 0;
    var res = re.exec(str);
    if(!res) return -1;
    return re.lastIndex - res[0].length;
};

function reLastIndexOf(reIn, str, startIndex) {
    var src = /\$$/.test(reIn.source) && !/\\\$$/.test(reIn.source) ? reIn.source : reIn.source + '(?![\\S\\s]*' + reIn.source + ')';
    var re = new RegExp(src, 'g' + (reIn.ignoreCase ? 'i' : '') + (reIn.multiLine ? 'm' : ''));
    re.lastIndex = startIndex || 0;
    var res = re.exec(str);
    if(!res) return -1;
    return re.lastIndex - res[0].length;
};

reIndexOf(/[abc]/, "tommy can eat");  // Returns 6
reIndexOf(/[abc]/, "tommy can eat", 8);  // Returns 11
reLastIndexOf(/[abc]/, "tommy can eat"); // Returns 11

You could also prototype the functions onto the RegExp object:

RegExp.prototype.indexOf = function(str, startIndex) {
    var re = new RegExp(this.source, 'g' + (this.ignoreCase ? 'i' : '') + (this.multiLine ? 'm' : ''));
    re.lastIndex = startIndex || 0;
    var res = re.exec(str);
    if(!res) return -1;
    return re.lastIndex - res[0].length;
};

RegExp.prototype.lastIndexOf = function(str, startIndex) {
    var src = /\$$/.test(this.source) && !/\\\$$/.test(this.source) ? this.source : this.source + '(?![\\S\\s]*' + this.source + ')';
    var re = new RegExp(src, 'g' + (this.ignoreCase ? 'i' : '') + (this.multiLine ? 'm' : ''));
    re.lastIndex = startIndex || 0;
    var res = re.exec(str);
    if(!res) return -1;
    return re.lastIndex - res[0].length;
};


/[abc]/.indexOf("tommy can eat");  // Returns 6
/[abc]/.indexOf("tommy can eat", 8);  // Returns 11
/[abc]/.lastIndexOf("tommy can eat"); // Returns 11

A quick explanation of how I am modifying the RegExp: For indexOf I just have to ensure that the global flag is set. For lastIndexOf of I am using a negative look-ahead to find the last occurrence unless the RegExp was already matching at the end of the string.

You should be able to install m2e (maven project for eclipse) using the Help -> Install New Software dialog. On that dialog open the Juno site (http://download.eclipse.org/releases/juno) and expand the Collaboration group (or type m2e into the filter). Select the two m2e options and follow the installation dialog

React.createClass method has been deprecated in the new version of React, you can do it very simply in the following way make one functional component and another class component to maintain state:

Parent:

const ParentComp = () => {_x000D_
  _x000D_
  getLanguage = (language) => {_x000D_
    console.log('Language in Parent Component: ', language);_x000D_
  }_x000D_
  _x000D_
  <ChildComp onGetLanguage={getLanguage}_x000D_
};

Child:

class ChildComp extends React.Component {_x000D_
    state = {_x000D_
      selectedLanguage: ''_x000D_
    }_x000D_
    _x000D_
    handleLangChange = e => {_x000D_
        const language = e.target.value;_x000D_
        thi.setState({_x000D_
          selectedLanguage = language;_x000D_
        });_x000D_
        this.props.onGetLanguage({language}); _x000D_
    }_x000D_
_x000D_
    render() {_x000D_
        const json = require("json!../languages.json");_x000D_
        const jsonArray = json.languages;_x000D_
        const selectedLanguage = this.state;_x000D_
        return (_x000D_
            <div >_x000D_
                <DropdownList ref='dropdown'_x000D_
                    data={jsonArray} _x000D_
                    value={tselectedLanguage}_x000D_
                    caseSensitive={false} _x000D_
                    minLength={3}_x000D_
                    filter='contains'_x000D_
                    onChange={this.handleLangChange} />_x000D_
            </div>            _x000D_
        );_x000D_
    }_x000D_
};

The other answers here involving marking the protocol as "@objc" do not work when using swift-specific types.

struct Info {
    var height: Int
    var weight: Int
} 

@objc protocol Health {
    func isInfoHealthy(info: Info) -> Bool
} 
//Error "Method cannot be marked @objc because the type of the parameter cannot be represented in Objective-C"

In order to declare optional protocols that work well with swift, declare the functions as variables instead of func's.

protocol Health {
    var isInfoHealthy: (Info) -> (Bool)? { get set }
}

And then implement the protocol as follows

class Human: Health {
    var isInfoHealthy: (Info) -> (Bool)? = { info in
        if info.weight < 200 && info.height > 72 {
            return true
        }
        return false
    }
    //Or leave out the implementation and declare it as:  
    //var isInfoHealthy: (Info) -> (Bool)?
}

You can then use "?" to check whether or not the function has been implemented

func returnEntity() -> Health {
    return Human()
}

var anEntity: Health = returnEntity()

var isHealthy = anEntity.isInfoHealthy(Info(height: 75, weight: 150))? 
//"isHealthy" is true

When you create local variables inside a function that are created on the stack, they most likely get overwritten in memory when exiting the function.

So code like this in most C++ implementations will not work:

char[] populateChar()
{
    char* ch = "wonet return me";
    return ch;
}

A fix is to create the variable that want to be populated outside the function or where you want to use it, and then pass it as a parameter and manipulate the function, example:

void populateChar(char* ch){
    strcpy(ch, "fill me, Will. This will stay", size); // This will work as long as it won't overflow it.
}

int main(){
    char ch[100]; // Reserve memory on the stack outside the function
    populateChar(ch); // Populate the array
}

A C++11 solution using std::move(ch) to cast lvalues to rvalues:

void populateChar(char* && fillme){
    fillme = new char[20];
    strcpy(fillme, "this worked for me");
}

int main(){
    char* ch;
    populateChar(std::move(ch));
    return 0;
}

Or this option in C++11:

char* populateChar(){
    char* ch = "test char";
    // Will change from lvalue to r value
    return std::move(ch);
}

int main(){
    char* ch = populateChar();
    return 0;
}

an existing folder will FAIL with FileExists

Function FileExists(strFileName)
' Check if a file exists - returns True or False

use instead or in addition:

' Check if a path exists

TEXT is used for large pieces of string data. If the length of the field exceeed a certain threshold, the text is stored out of row.

VARCHAR is always stored in row and has a limit of 8000 characters. If you try to create a VARCHAR(x), where x > 8000, you get an error:

Server: Msg 131, Level 15, State 3, Line 1

The size () given to the type ‘varchar’ exceeds the maximum allowed for any data type (8000)

These length limitations do not concern VARCHAR(MAX) in SQL Server 2005, which may be stored out of row, just like TEXT.

Note that MAX is not a kind of constant here, VARCHAR and VARCHAR(MAX) are very different types, the latter being very close to TEXT.

In prior versions of SQL Server you could not access the TEXT directly, you only could get a TEXTPTR and use it in READTEXT and WRITETEXT functions.

In SQL Server 2005 you can directly access TEXT columns (though you still need an explicit cast to VARCHAR to assign a value for them).

TEXT is good:

• If you need to store large texts in your database
• If you do not search on the value of the column
• If you select this column rarely and do not join on it.

VARCHAR is good:

• If you store little strings
• If you search on the string value
• If you always select it or use it in joins.

By selecting here I mean issuing any queries that return the value of the column.

By searching here I mean issuing any queries whose result depends on the value of the TEXT or VARCHAR column. This includes using it in any JOIN or WHERE condition.

As the TEXT is stored out of row, the queries not involving the TEXT column are usually faster.

Some examples of what TEXT is good for:

• Blog comments
• Wiki pages
• Code source

Some examples of what VARCHAR is good for:

• Usernames
• Page titles
• Filenames

As a rule of thumb, if you ever need you text value to exceed 200 characters AND do not use join on this column, use TEXT.

Otherwise use VARCHAR.

P.S. The same applies to UNICODE enabled NTEXT and NVARCHAR as well, which you should use for examples above.

P.P.S. The same applies to VARCHAR(MAX) and NVARCHAR(MAX) that SQL Server 2005+ uses instead of TEXT and NTEXT. You'll need to enable large value types out of row for them with sp_tableoption if you want them to be always stored out of row.

As mentioned above and here, TEXT is going to be deprecated in future releases:

The text in row option will be removed in a future version of SQL Server. Avoid using this option in new development work, and plan to modify applications that currently use text in row. We recommend that you store large data by using the varchar(max), nvarchar(max), or varbinary(max) data types. To control in-row and out-of-row behavior of these data types, use the large value types out of row option.

Pretty much the same way that you always have, with "Modules" instead of classes and just use "Public" instead of the old "Global" keyword:

Public Module Module1
    Public Foo As Integer
End Module

Tonny Madsen said it right, but sometimes this is too simplistic.

What if you want to be more selective in your replacements since not all replacements are correct for what you're trying to do?

Here's how to get more granularity to do the replacements only in certain folders, files, or instances:

First, do like he said:

• Click Search --> File... OR press Ctrl + H and choose the "File Search" tab.
• Enter text, file pattern and choose your Workspace or Working Set.

Then:

• Click Search
• When your results come up, make some folder, file, or instance selections by Ctrl + clicking on the ones you'd like to select. Ex: here's my selection. I've chosen 3 instances, 1 file, and 1 folder:

• Now, right-click on your selection and go to --> Replace Selected.... Here's a screenshot of that:

• Enter what you'd like to replace it "With". In my case you can see it says it is "Replacing 190 matches in 4 files". Now click OK.

Voilà!

As documented under CREATE TABLE Syntax:

Note
The older TYPE option was synonymous with ENGINE. TYPE was deprecated in MySQL 4.0 and removed in MySQL 5.5. When upgrading to MySQL 5.5 or later, you must convert existing applications that rely on TYPE to use ENGINE instead.

Therefore, you want:

CREATE TABLE dave_bannedwords(
  id   INT(11)     NOT NULL AUTO_INCREMENT,
  word VARCHAR(60) NOT NULL DEFAULT '',
  PRIMARY KEY (id),
  KEY id(id) -- this is superfluous in the presence of your PK, ergo unnecessary
) ENGINE = MyISAM ;

a recursive solution:

function thousands(amount) {
  if( /\d{3}\d+/.test(amount) ) {
    return thousands(amount.replace(/(\d{3}?)(,|$)/, ',$&'));
  }
  return amount;
}

another split solution:

function thousands (amount) {
  return amount
    // reverse string
    .split('')
    .reverse()
    .join('')
    // grouping starting by units
    .replace(/\d{3}/g, '$&,')
    // reverse string again
    .split('')
    .reverse()
    .join('');
}

Why not just add Labels to the top of the Listbox and if changes are needed, the only thing you need to programmatically change are the labels.

$('#availability').find('option:selected').val() // For Value 
$('#availability').find('option:selected').text() // For Text
or 
$('#availability option:selected').val() // For Value 
$('#availability option:selected').text() // For Text

You can see that your locks are pretty much working as you are using them, if you slow down the process and make them block a bit more. You had the right idea, where you surround critical pieces of code with the lock. Here is a small adjustment to your example to show you how each waits on the other to release the lock.

import threading
import time
import inspect

class Thread(threading.Thread):
    def __init__(self, t, *args):
        threading.Thread.__init__(self, target=t, args=args)
        self.start()

count = 0
lock = threading.Lock()

def incre():
    global count
    caller = inspect.getouterframes(inspect.currentframe())[1][3]
    print "Inside %s()" % caller
    print "Acquiring lock"
    with lock:

final indicates that the value of the variable won't change - in other words, a constant whose value can't be modified after it is declared.

Use public final static String when you want to create a String that:

1. belongs to the class (static: no instance necessary to use it), and that
2. won't change (final), for instance when you want to define a String constant that will be available to all instances of the class, and to other objects using the class.

Example:

public final static String MY_CONSTANT = "SomeValue";

// ... in some other code, possibly in another object, use the constant:
if (input.equals(MyClass.MY_CONSTANT)

Similarly:

public static final int ERROR_CODE = 127;

It isn't required to use final, but it keeps a constant from being changed inadvertently during program execution, and serves as an indicator that the variable is a constant.

Even if the constant will only be used - read - in the current class and/or in only one place, it's good practice to declare all constants as final: it's clearer, and during the lifetime of the code the constant may end up being used in more than one place.

Furthermore using final may allow the implementation to perform some optimization, e.g. by inlining an actual value where the constant is used.

It turns out that OpenSSL is compiled and enabled in php 5.3 of XAMPP 1.7.2 and so no longer requires a separate extension dll.

However, you STILL need to enable it in your PHP.ini file the line extension=php_openssl.dll

I'm pretty sure the code is not using the System.Net.Http.HttpContent class, but instead Microsoft.Http.HttpContent. Microsoft.Http was the WCF REST Starter Kit, which never made it out preview before being placed in the .NET Framework. You can still find it here: http://aspnet.codeplex.com/releases/view/24644

I would not recommend basing new code on it.

I was able to do that by using \n in the line parameter.

It is specially useful if the file can be validated, and adding a single line generates an invalid file.

In my case, I was adding AuthorizedKeysCommand and AuthorizedKeysCommandUser to sshd_config, with the following command:

- lineinfile: dest=/etc/ssh/sshd_config line='AuthorizedKeysCommand /etc/ssh/ldap-keys\nAuthorizedKeysCommandUser nobody' validate='/usr/sbin/sshd -T -f %s'

Adding only one of the options generates a file that fails validation.

It's perfectly possible to update multiple columns in the same statement, and in fact your code is doing it. So why does it seem that "INV_TOTAL is not updating, only the inv_discount"?

Because you're updating INV_TOTAL with INV_DISCOUNT, and the database is going to use the existing value of INV_DISCOUNT and not the one you change it to. So I'm afraid what you need to do is this:

UPDATE INVOICE
   SET INV_DISCOUNT = DISC1 * INV_SUBTOTAL
     , INV_TOTAL    = INV_SUBTOTAL - (DISC1 * INV_SUBTOTAL)     
WHERE INV_ID = I_INV_ID;

        

Perhaps that seems a bit clunky to you. It is, but the problem lies in your data model. Storing derivable values in the table, rather than deriving when needed, rarely leads to elegant SQL.

Could you try something like this for example I think what you are wanting to utilize is the port.ReadExisting() Method

 using System;
 using System.IO.Ports;

 class SerialPortProgram 
 { 
  // Create the serial port with basic settings 
    private SerialPort port = new   SerialPort("COM1",
      9600, Parity.None, 8, StopBits.One); 
    [STAThread] 
    static void Main(string[] args) 
    { 
      // Instatiate this 
      SerialPortProgram(); 
    } 

    private static void SerialPortProgram() 
    { 
        Console.WriteLine("Incoming Data:");
         // Attach a method to be called when there
         // is data waiting in the port's buffer 
        port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); 
        // Begin communications 
        port.Open(); 
        // Enter an application loop to keep this thread alive 
        Console.ReadLine();
     } 

    private void port_DataReceived(object sender, SerialDataReceivedEventArgs e) 
    { 
       // Show all the incoming data in the port's buffer
       Console.WriteLine(port.ReadExisting()); 
    } 
}

Or is you want to do it based on what you were trying to do , you can try this

public class MySerialReader : IDisposable
{
  private SerialPort serialPort;
  private Queue<byte> recievedData = new Queue<byte>();

  public MySerialReader()
  {
    serialPort = new SerialPort();
    serialPort.Open();
    serialPort.DataReceived += serialPort_DataReceived;
  }

  void serialPort_DataReceived(object s, SerialDataReceivedEventArgs e)
  {
    byte[] data = new byte[serialPort.BytesToRead];
    serialPort.Read(data, 0, data.Length);
    data.ToList().ForEach(b => recievedData.Enqueue(b));
    processData();
  }

  void processData()
  {
    // Determine if we have a "packet" in the queue
    if (recievedData.Count > 50)
    {
        var packet = Enumerable.Range(0, 50).Select(i => recievedData.Dequeue());
    }
  }

  public void Dispose()
  {
        if (serialPort != null)
        {
            serialPort.Dispose();
        }
  }

As for me resetConfig only works

this.router.resetConfig(newRoutes);

Or concat with previous

this.router.resetConfig([...newRoutes, ...this.router.config]);

But keep in mind that the last must be always route with path **

As mentioned in some of the comments, ReactDOM.render no longer returns the component instance. You can pass a ref callback in when rendering the root of the component to get the instance, like so:

// React code (jsx)
function MyWidget(el, refCb) {
    ReactDOM.render(<MyComponent ref={refCb} />, el);
}
export default MyWidget;

and:

// vanilla javascript code
var global_widget_instance;

MyApp.MyWidget(document.getElementById('my_container'), function(widget) {
    global_widget_instance = widget;
});

global_widget_instance.myCoolMethod();

You'll need to send the image back base64 encoded, look at this: http://php.net/manual/en/function.base64-encode.php

Then in your ajax call change the success function to this:

$('.div_imagetranscrits').html('<img src="data:image/png;base64,' + data + '" />');

After changing the path you have to restart powershell. You do not need to restart your computer.

What database are you on? With MS SQL Server, it's a database-wide setting, or you can over-ride it per-query with the COLLATE keyword.

SigSegV means a signal for memory access violation, trying to read or write from/to a memory area that your process does not have access to. These are not C or C++ exceptions and you can’t catch signals. It’s possible indeed to write a signal handler that ignores the problem and allows continued execution of your unstable program in undefined state, but it should be obvious that this is a very bad idea.

Most of the time this is because of a bug in the program. The memory address given can help debug what’s the problem (if it’s close to zero then it’s likely a null pointer dereference, if the address is something like 0xadcedfe then it’s intentional safeguard or a debug check, etc.)

One way of “catching” the signal is to run your stuff in a separate child process that can then abruptly terminate without taking your main process down with it. Finding the root cause and fixing it is obviously preferred over workarounds like this.

For a field separator of any number 2 through 5 or letter a or # or a space, where the separating character must be repeated at least 2 times and not more than 6 times, for example:

awk -F'[2-5a# ]{2,6}' ...

I am sure variations of this exist using ( ) and parameters

For me I doing this:

import paramiko
hostname = 'my hostname or IP' 
myuser   = 'the user to ssh connect'
mySSHK   = '/path/to/sshkey.pub'
sshcon   = paramiko.SSHClient()  # will create the object
sshcon.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # no known_hosts error
sshcon.connect(hostname, username=myuser, key_filename=mySSHK) # no passwd needed

works for me pretty ok

     print rows[row_number][column_number]

Note: list(csv.reader(f)) loads the whole file in memory. To avoid that you could use itertools:

import itertools

     row = next(itertools.islice(csv.reader(f), row_number, row_number+1))

If you are passing package name as parameter to any of your user defined function then use the below code :

    Intent intent=new Intent(Intent.ACTION_DELETE);
    intent.setData(Uri.parse("package:"+packageName));
    startActivity(intent);

It can be treated as defensive programming approach from the compiler - the variables must be assigned before it can be used.

You must use the same Tokenizer you used to build your model!

Else this will give different vector to each word.

Then, I am using:

phrase = "not good"
tokens = myTokenizer.texts_to_matrix([phrase])

model.predict(np.array(tokens))

If the NFS server disappeared and you can't get it back online, one trick that I use is to add an alias to the interface with the IP of the NFS server (in this example, 192.0.2.55).

Linux

The command for that is something roughly like:

ifconfig eth0:fakenfs 192.0.2.55 netmask 255.255.255.255

Where 192.0.2.55 is the IP of the NFS server that went away. You should then be able to ping the address, and you should also be able to unmount the filesystem (use unmount -f). You should then destroy the aliased interface so you no longer route traffic to the old NFS server to yourself with:

ifconfig eth0:fakenfs down

FreeBSD and similar operating systems

The command would be something like:

ifconfig em0 alias 192.0.2.55 netmask 255.255.255.255

And then to remove it:

ifconfig em0 delete 192.0.2.55

man ifconfig(8) for more!

From git-blame:

Annotates each line in the given file with information from the revision which last modified the line. Optionally, start annotating from the given revision.

When specified one or more times, -L restricts annotation to the requested lines.

Example:

[email protected]:~# git blame .htaccess
...
^e1fb2d7 (John Doe 2015-07-03 06:30:25 -0300  4) allow from all
^72fgsdl (Arthur King 2015-07-03 06:34:12 -0300  5)
^e1fb2d7 (John Doe 2015-07-03 06:30:25 -0300  6) <IfModule mod_rewrite.c>
^72fgsdl (Arthur King 2015-07-03 06:34:12 -0300  7)     RewriteEngine On
...

Please note that git blame does not show the per-line modifications history in the chronological sense. It only shows who was the last person to have changed a line in a document up to the last commit in HEAD.

That is to say that in order to see the full history/log of a document line, you would need to run a git blame path/to/file for each commit in your git log.

If you want to remove the entire row from DataTable ,

try this

DataTable dt = new DataTable();  //User DataTable
DataRow[] rows;
rows = dt.Select("Student=' " + id + " ' ");
foreach (DataRow row in rows)
     dt.Rows.Remove(row);

I had the exact same problem yesterday working through problem 2-3 in Accelerated C++. The key is to change all variables you will be comparing (using Boolean operators) to compatible types. In this case, that means string::size_type (or unsigned int, but since this example is using the former, I will just stick with that even though the two are technically compatible).

Notice that in their original code they did exactly this for the c counter (page 30 in Section 2.5 of the book), as you rightly pointed out.

What makes this example more complicated is that the different padding variables (padsides and padtopbottom), as well as all counters, must also be changed to string::size_type.

Getting to your example, the code that you posted would end up looking like this:

cout << "Please enter the size of the frame between top and bottom";
string::size_type padtopbottom;
cin >> padtopbottom;

cout << "Please enter size of the frame from each side you would like: ";
string::size_type padsides; 
cin >> padsides;

string::size_type c = 0; // definition of c in the program

if (r == padtopbottom + 1 && c == padsides + 1) { // where the error no longer occurs

Notice that in the previous conditional, you would get the error if you didn't initialize variable r as a string::size_type in the for loop. So you need to initialize the for loop using something like:

    for (string::size_type r=0; r!=rows; ++r)   //If r and rows are string::size_type, no error!

So, basically, once you introduce a string::size_type variable into the mix, any time you want to perform a boolean operation on that item, all operands must have a compatible type for it to compile without warnings.

You should be able to use the IF function for that. the syntax is =IF(condition, value_if_true, value_if_false). To add an extra column with only the non-reimbursed amounts, you would use something like:

=IF(B1="No", A1, 0)

and sum that. There's probably a way to include it in a single cell below the column as well, but off the top of my head I can't think of anything simple.

It seems there's some misunderstanding. So, instead of trying to patch VS2013 here's and answer from a Microsoft guy: https://social.msdn.microsoft.com/Forums/vstudio/en-US/49ba9a67-d26a-4b21-80ef-caeb081b878e/will-c-60-ever-be-supported-by-vs-2013?forum=roslyn

So, please, read it and install VS2015.

No, it's not possible, as the styling for these elements is handled by the user's OS. MSDN will answer your question here:

Except for background-color and color, style settings applied through the style object for the option element are ignored.

Use the dist() function, but you need to form a matrix from the two inputs for the first argument to dist():

dist(rbind(x1, x2))

For the input in the OP's question we get:

> dist(rbind(x1, x2))
        x1
x2 7.94821

a single value that is the Euclidean distance between x1 and x2.

Generally, make an "inverse" commit, using:

git revert 364705c

then send it to the remote as usual:

git push

This won't delete the commit: it makes an additional commit that undoes whatever the first commit did. Anything else, not really safe, especially when the changes have already been propagated.

A small modification to answer from Alex is turning on and off of auto calculation.

Surprisingly the unmodified code was working fine with VLOOKUP but failed with OFFSET. Also turning auto calculation off speeds up the save drastically.

Seth Robertson's Link 2 said "For thorough understanding of those terms, refer to Linux kernel book like Linux Kernel Development by Robert M. Love."

I found some contents about 'buffer' in the 2nd edition of the book.

Although the physical device itself is addressable at the sector level, the kernel performs all disk operations in terms of blocks.

When a block is stored in memory (say, after a read or pending a write), it is stored in a 'buffer'. Each 'buffer' is associated with exactly one block. The 'buffer' serves as the object that represents a disk block in memory.

A 'buffer' is the in-memory representation of a single physical disk block.

Block I/O operations manipulate a single disk block at a time. A common block I/O operation is reading and writing inodes. The kernel provides the bread() function to perform a low-level read of a single block from disk. Via 'buffers', disk blocks are mapped to their associated in-memory pages. "

SOLVED

My biggest "D'oh" moment! I've been compiling it on Eclipse rather than cmd which was where I was executing it. So my newly compiled classes went to the bin folder and the compiled class file via command prompt remained the same in my src folder. I recompiled with my new code and it works like a charm.

File fold = new File("../playlist/" + existingPlaylist.getText() + ".txt");
fold.delete();

File fnew = new File("../playlist/" + existingPlaylist.getText() + ".txt");

String source = textArea.getText();
System.out.println(source);

try {
    FileWriter f2 = new FileWriter(fnew, false);
    f2.write(source);
    f2.close();

} catch (IOException e) {
    e.printStackTrace();
}   

List myList = new ArrayList();
Collections.addAll(myList, filesOrig); 

You Can use this header

   header('Content-type: text/html; charset=UTF-8');

and after decoding the string

 $page = utf8_decode(curl_exec($ch));

It worked for me

The function you're looking for is 'Insert'. It takes as its parameters the index you want to insert at, and an array of values to use for the new row values. Typical usage might include:

myDataGridView.Rows.Insert(4,new object[]{value1,value2,value3});

or something to that effect.

With New-Item you can add the Force parameter

New-Item -Force -ItemType directory -Path foo

Or the ErrorAction parameter

New-Item -ErrorAction Ignore -ItemType directory -Path foo

I'd say:

 <a href="#"id="buttonOne">
            <div id="linkedinB">
                <img src="img/linkedinB.png" width="40" height="40">
            </div>
      </div> 

However, it will still be a link. If you want to change your link into a button, you should rename the #buttonone to #buttonone a { your css here }.

It looks like this issue has to do with the difference between the Content-Type and Accept headers. In HTTP, Content-Type is used in request and response payloads to convey the media type of the current payload. Accept is used in request payloads to say what media types the server may use in the response payload.

So, having a Content-Type in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type does matter.

If a server is not able to process the Content-Type of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept header, it will return a 406 error.)

In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.

You could fix this in one of two ways:

1. Make the Content-Type "application/json;odata=verbose" in your POST request, or

2. Include the DataServiceVersion header in the request and set it be less than v3. For example:

   DataServiceVersion: 2.0;
   

(Option 2 assumes that you aren't using any v3 features in your request payload.)

This issue was even more strange for us. Everything worked if you had previously visited the sharepoint site from the browser, before you made the SOAP call. However, if you did the SOAP call first we'd throw the above error.

We were able to resolve this issue by installing the sharepoint certificate on the client and adding the domain to the local intranet sites.

The problem is that you are using SingleOrDefault. This method will only succeed when the collections contains exactly 0 or 1 element. I believe you are looking for FirstOrDefault which will succeed no matter how many elements are in the collection.

We do this kind of XML parsing all the time. The key is defining where the parsing method will leave the reader on exit. If you always leave the reader on the next element following the element that was first read then you can safely and predictably read in the XML stream. So if the reader is currently indexing the <Account> element, after parsing the reader will index the </Accounts> closing tag.

The parsing code looks something like this:

public class Account
{
    string _accountId;
    string _nameOfKin;
    Statements _statmentsAvailable;

    public void ReadFromXml( XmlReader reader )
    {
        reader.MoveToContent();

        // Read node attributes
        _accountId = reader.GetAttribute( "accountId" );
        ...

        if( reader.IsEmptyElement ) { reader.Read(); return; }

        reader.Read();
        while( ! reader.EOF )
        {
            if( reader.IsStartElement() )
            {
                switch( reader.Name )
                {
                    // Read element for a property of this class
                    case "NameOfKin":
                        _nameOfKin = reader.ReadElementContentAsString();
                        break;

                    // Starting sub-list
                case "StatementsAvailable":
                    _statementsAvailable = new Statements();
                    _statementsAvailable.Read( reader );
                    break;

                    default:
                        reader.Skip();
                }
            }
            else
            {
                reader.Read();
                break;
            }
        }       
    }
}

The Statements class just reads in the <StatementsAvailable> node

public class Statements
{
    List<Statement> _statements = new List<Statement>();

    public void ReadFromXml( XmlReader reader )
    {
        reader.MoveToContent();
        if( reader.IsEmptyElement ) { reader.Read(); return; }

        reader.Read();
        while( ! reader.EOF )
        {
            if( reader.IsStartElement() )
            {
                if( reader.Name == "Statement" )
                {
                    var statement = new Statement();
                    statement.ReadFromXml( reader );
                    _statements.Add( statement );               
                }
                else
                {
                    reader.Skip();
                }
            }
            else
            {
                reader.Read();
                break;
            }
        }
    }
}

The Statement class would look very much the same

public class Statement
{
    string _satementId;

    public void ReadFromXml( XmlReader reader )
    {
        reader.MoveToContent();

        // Read noe attributes
        _statementId = reader.GetAttribute( "statementId" );
        ...

        if( reader.IsEmptyElement ) { reader.Read(); return; }

        reader.Read();
        while( ! reader.EOF )
        {           
            ....same basic loop
        }       
    }
}

"Program to interface" means don't provide hard code right the way, meaning your code should be extended without breaking the previous functionality. Just extensions, not editing the previous code.

//div[@id='..' and @class='...]

should do the trick. That's selecting the div operators that have both attributes of the required value.

It's worth using one of the online XPath testbeds to try stuff out.

Better result for me:

ls -1 | xargs -L1 -d "\n" CMD

Here's the VB.Net solution that I've used.

First make a class to compare dates:

Private Class DateComparer
    Implements System.Collections.IComparer

    Public Function Compare(ByVal info1 As Object, ByVal info2 As Object) As Integer Implements System.Collections.IComparer.Compare
        Dim FileInfo1 As System.IO.FileInfo = DirectCast(info1, System.IO.FileInfo)
        Dim FileInfo2 As System.IO.FileInfo = DirectCast(info2, System.IO.FileInfo)

        Dim Date1 As DateTime = FileInfo1.CreationTime
        Dim Date2 As DateTime = FileInfo2.CreationTime

        If Date1 > Date2 Then Return 1
        If Date1 < Date2 Then Return -1
        Return 0
    End Function
End Class

Then use the comparer while sorting the array:

Dim DirectoryInfo As New System.IO.DirectoryInfo("C:\")
Dim Files() As System.IO.FileInfo = DirectoryInfo.GetFiles()
Dim comparer As IComparer = New DateComparer()
Array.Sort(Files, comparer)

I found that this error occurred when I extracted the .rpm file.

I then removed that folder and downloaded jdk-7u79-linux-x64.tar.gz for Linux 64 and extracted the contents of this file instead. Also: export JAVA_HOME=/opt/java/jdk1.7.0_79 export JDK_HOME=/opt/java/jdk1.7.0_79 export PATH=${JAVA_HOME}/bin

you can use RETURNING clause in INSERT statement,just like the following

wgzhao=# create table foo(id int,name text);
CREATE TABLE
wgzhao=# insert into foo values(1,'wgzhao') returning id;
 id 
----
  1
(1 row)

INSERT 0 1
wgzhao=# insert into foo values(3,'wgzhao') returning id;
 id 
----
  3
(1 row)

INSERT 0 1

wgzhao=# create table bar(id serial,name text);
CREATE TABLE
wgzhao=# insert into bar(name) values('wgzhao') returning id;
 id 
----
  1
(1 row)

INSERT 0 1
wgzhao=# insert into bar(name) values('wgzhao') returning id;
 id 
----
  2
(1 row)

INSERT 0 

Since I don't have a 50 reputation Stackoverflow wont let me comment on the second best answer. Found another trick for finding the culprit label in the Storyboard.

So once you know the id of the label, open your storyboard in a seperate tab with view controllers displayed and just do command F and command V and will take you straight to that label :)

To find ANY and ALL unicode error related... Using the following command:

grep -r -P '[^\x00-\x7f]' /etc/apache2 /etc/letsencrypt /etc/nginx

Found mine in

/etc/letsencrypt/options-ssl-nginx.conf:        # The following CSP directives don't use default-src as

Another possible cause of similar issue could be wrong processorArchitecture in the cx_freeze manifest, trying to load x86 common controls dll in x64 process - should be fixed by this patch:

https://bitbucket.org/anthony_tuininga/cx_freeze/pull-request/71/changed-x86-in-windows-manifest-to/diff

Here's what worked for me:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <false/>
    <key>NSExceptionDomains</key>
    <dict>

            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <true/>
        </dict>
    <!-- add more domain here -->
    </dict>
</dict>

I just wanna add this to help others and save some time:

if you are using: CFStreamCreatePairWithSocketToHost. make sure your host is the same with what you have in your .plist or if you have separate domain for socket just add it there.

CFStreamCreatePairWithSocketToHost(NULL, (__bridge CFStringRef)/*from .plist*/, (unsigned int)port, &readStream, &writeStream);

Hope this is helpful. Cheers. :)

You would need a mapping provider for MySQL. That is an extra thing the Entity Framework needs to make the magic happen. This blog talks about other mapping providers besides the one Microsoft is supplying. I haven't found any mentionings of MySQL.

You can create the element with border with the same color of your background, then when you want the border to show, just change its color.

You want to replace the values in a dataset column, but you're getting an error like this:

invalid factor level, NA generated

Try this instead:

levels(dataframe$column)[levels(dataframe$column)=='old_value'] <- 'new_value'

sleep(3) is in unistd.h, not stdlib.h. Type man 3 sleep on your command line to confirm for your machine, but I presume you're on a Mac since you're learning Objective-C, and on a Mac, you need unistd.h.

You can finish the Acivity and recreate it afterwards in this way your activity will be created again and all the views will be created with the new theme.

I have tried using the regular expressions listed above, but they do not work for the following:

SELECT '12 INCHES' REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$' FROM ...

The above will return 1 (TRUE), meaning the test of the string '12 INCHES' against the regular expression above, returns TRUE. It looks like a number based on the regular expression used above. In this case, because the 12 is at the beginning of the string, the regular expression interprets it as a number.

The following will return the right value (i.e. 0) because the string starts with characters instead of digits

SELECT 'TOP 10' REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$' FROM ...

The above will return 0 (FALSE) because the beginning of the string is text and not numeric.

However, if you are dealing with strings that have a mix of numbers and letters that begin with a number, you will not get the results you want. REGEXP will interpret the string as a valid number when in fact it is not.

If you put

window.location.reload(true);

at the beginning of your page with no other condition qualifying why that code runs, the page will load and then continue to reload itself until you close your browser.

For dynamic values!

<div class="col-md-4" ng-repeat="(k, v) in tiposAcesso">
    <label class="control-label">
        <input type="radio" name="tipoAcesso" ng-model="userLogin.tipoAcesso" value="{{k}}" ng-change="changeTipoAcesso(k)" />              
        <span ng-bind="v"></span>
    </label>
</div>

in controller

$scope.changeTipoAcesso = function(value) {
    console.log(value);
};

Set

android:descendantFocusability="blocksDescendants"

for yor ViewGroup view. All descendants will not take focus.

I recommend using the awesome requests library:

import requests

url = 'http://maps.googleapis.com/maps/api/directions/json'

params = dict(
    origin='Chicago,IL',
    destination='Los+Angeles,CA',
    waypoints='Joplin,MO|Oklahoma+City,OK',
    sensor='false'
)

resp = requests.get(url=url, params=params)
data = resp.json() # Check the JSON Response Content documentation below

JSON Response Content: https://requests.readthedocs.io/en/master/user/quickstart/#json-response-content

Very simple. Just follow these procedure:
1. git status
2. git add {File_Name} //the file name you haven been changed
3. git status
4. git commit -m '{your_message}'
5. git push origin master

I had the same problem today. My persistence.xml was in the wrong location. I had to put it in the following path:

project/src/main/resources/META-INF/persistence.xml

alter table your_table
alter column LoginDate datetime;

An alternative way is to just bundle without the gem group that contains the things you don't have.

So do:

bundle install --without assets

you don't have to modify the Gemfile at all, providing of course you are not doing asset chain stuff - which usually applies in non-development environments. Bundle will remember your '--without' setting in the .bundle/config file.

You can do so by creating an array of dtype=object. If you try to assign a long string to a normal numpy array, it truncates the string:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'])
>>> a[2] = 'bananas'
>>> a
array(['apples', 'foobar', 'banana'], 
      dtype='|S6')

But when you use dtype=object, you get an array of python object references. So you can have all the behaviors of python strings:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'], dtype=object)
>>> a
array([apples, foobar, cowboy], dtype=object)
>>> a[2] = 'bananas'
>>> a
array([apples, foobar, bananas], dtype=object)

Indeed, because it's an array of objects, you can assign any kind of python object to the array:

>>> a[2] = {1:2, 3:4}
>>> a
array([apples, foobar, {1: 2, 3: 4}], dtype=object)

However, this undoes a lot of the benefits of using numpy, which is so fast because it works on large contiguous blocks of raw memory. Working with python objects adds a lot of overhead. A simple example:

>>> a = numpy.array(['abba' for _ in range(10000)])
>>> b = numpy.array(['abba' for _ in range(10000)], dtype=object)
>>> %timeit a.copy()
100000 loops, best of 3: 2.51 us per loop
>>> %timeit b.copy()
10000 loops, best of 3: 48.4 us per loop

For creating session only cookie with java script, you can use the following. This works for me.

document.cookie = "cookiename=value; expires=0; path=/";

then get cookie value as following

 //get cookie 
var cookiename = getCookie("cookiename");
if (cookiename == "value") {
    //write your script
}

//function getCookie        
function getCookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1);
        if (c.indexOf(name) != -1) return c.substring(name.length, c.length);
    }
    return "";
}

Okay to support IE we can leave "expires" completely and can use this

document.cookie = "mtracker=somevalue; path=/";

This may be what your after:

SELECT Count(Owner_ID), Name
FROM (
    SELECT M.Owner_ID, O.Name, T.Type
    FROM Transport As T, Owner As O, Motorbike As M
    WHERE T.Type = 'Motorbike'
    AND O.Owner_ID = M.Owner_ID
    AND T.Type_ID = M.Motorbike_ID

    UNION ALL

    SELECT C.Owner_ID, O.Name, T.Type
    FROM Transport As T, Owner As O, Car As C
    WHERE T.Type = 'Car'
    AND O.Owner_ID = C.Owner_ID
    AND T.Type_ID = C.Car_ID
)
GROUP BY Owner_ID

The accepted answer is the correct way to do this in most cases. However, there are some situations where you want to set the cookie header manually. Normally if you set a "Cookie" header it is ignored, but that's because HttpClientHandler defaults to using its CookieContainer property for cookies. If you disable that then by setting UseCookies to false you can set cookie headers manually and they will appear in the request, e.g.

var baseAddress = new Uri("http://example.com");
using (var handler = new HttpClientHandler { UseCookies = false })
using (var client = new HttpClient(handler) { BaseAddress = baseAddress })
{
    var message = new HttpRequestMessage(HttpMethod.Get, "/test");
    message.Headers.Add("Cookie", "cookie1=value1; cookie2=value2");
    var result = await client.SendAsync(message);
    result.EnsureSuccessStatusCode();
}

Here's an aparently free tool http://www.extradata.com/products/jarc/

Time::Piece (in core since Perl 5.10) also has a strftime function and by default overloads localtime and gmtime to return Time::Piece objects:

use Time::Piece;
print localtime->strftime('%Y-%m-%d');

or without the overridden localtime:

use Time::Piece (); 
print Time::Piece::localtime->strftime('%F %T');

There is a branch of conda (new-pypi-install) that adds better integration with pip and PyPI. In particular conda list will also show pip installed packages and conda install will first try to find a conda package and failing that will use pip to install the package.

This branch is scheduled to be merged later this week so that version 2.1 of conda will have better pip-integration with conda.

In that example, e is just a parameter for that function, but it's the event object that gets passed in through it.

To put it in another way, can we replicate the appearance of these text views without using the android:textAppearance attribute?

Like biegleux already said:

• small represents 14sp
• medium represents 18sp
• large represents 22sp

If you want to use the small, medium or large value on any text in your Android app, you can just create a dimens.xml file in your values folder and define the text size there with the following 3 lines:

<dimen name="text_size_small">14sp</dimen>
<dimen name="text_size_medium">18sp</dimen>
<dimen name="text_size_large">22sp</dimen>

Here is an example for a TextView with large text from the dimens.xml file:

<TextView
  android:id="@+id/hello_world"
  android:text="hello world"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:textSize="@dimen/text_size_large"/>

I suppose you have figured it out by now. The answer is hidden in your first mail itself.

The make command by default looks for makefile, Makefile, and GNUMakefile as the input file and you are having Makefile.txt in your folder. Just remove the file extension (.txt) and it should work.

You can use Microsoft.Office.Interop.Excel:

worksheet.Range[worksheet.Cells[rowNum, columnNum], worksheet.Cells[rowNum, columnNum]].Merge();

You can also use NPOI:

var cellsTomerge = new NPOI.SS.Util.CellRangeAddress(firstrow, lastrow, firstcol, lastcol);
_sheet.AddMergedRegion(cellsTomerge);

I'm surprised that nobody has mentioned the (very old but reliable) Absolute Columns technique: http://24ways.org/2008/absolute-columns/

In my opinion, it is far superior to both Faux Columns and One True Layout's technique.

The general idea is that an element with position: absolute; will position against the nearest parent element that has position: relative;. You then stretch a column to fill 100% height by assigning both a top: 0px; and bottom: 0px; (or whatever pixels/percentages you actually need.) Here's an example:

<!DOCTYPE html>
<html>
  <head>
    <style>
      #container
      {
        position: relative;
      }

      #left-column
      {
        width: 50%;
        background-color: pink;
      }

      #right-column
      {
        position: absolute;
        top: 0px;
        right: 0px;
        bottom: 0px;
        width: 50%;
        background-color: teal;
      }
    </style>
  </head>
  <body>
    <div id="container">
      <div id="left-column">
        <ul>
          <li>Foo</li>
          <li>Bar</li>
          <li>Baz</li>
        </ul>
      </div>
      <div id="right-column">
        Lorem ipsum
      </div>
    </div>
  </body>
</html>

Use '-R' to backup stored procedures, but also keep in mind that if you want a consistent dump of your database while its being modified you need to use --single-transaction (if you only backup innodb) or --lock-all-tables (if you also need myisam tables)

Hands down the easiest way to parse a HTML table is to use pandas.read_html() - it accepts both URLs and HTML.

import pandas as pd
url = r'https://en.wikipedia.org/wiki/List_of_S%26P_500_companies'
tables = pd.read_html(url) # Returns list of all tables on page
sp500_table = tables[0] # Select table of interest

Only downside is that read_html() doesn't preserve hyperlinks.

I have tested it. It works fine.

.row.vdivide [class*='col-']:not(:last-child):after {
      background: #e0e0e0;
      width: 1px;
      content: "";
      display:block;
      position: absolute;
      top:0;
      bottom: 0;
      right: 0;
      min-height: 70px;
    }

    <div class="container">
      <div class="row vdivide">
        <div class="col-sm-3 text-center"><h1>One</h1></div>
        <div class="col-sm-3 text-center"><h1>Two</h1></div>
        <div class="col-sm-3 text-center"><h1>Three</h1></div>
        <div class="col-sm-3 text-center"><h1>Four</h1></div>
      </div>
    </div>

If you are not using GitBash - you need to start your ssh-agent using this command

start-ssh-agent.cmd

This is brutally buried in the comments and hard to find. This should be accepted answer.

If your ssh agent is not set up, you can open PowerShell as admin and set it to manual mode

Get-Service -Name ssh-agent | Set-Service -StartupType Manual

Despite the question is specific to gitlab, but similar errors can happen on github, depending how it is set up (usually Github Enterprise).

You need to familiarize yourself with the following concepts:

• pre-receive hooks
• organization webhooks
• Webhooks

Webhooks are more commonly understood than other two items.

The Pre-receive hooks

are scripts that run on the GitHub Enterprise server to enforce policy. When a push occurs, each script runs in an isolated environment to determine whether the push is accepted or rejected.

Organization webhooks:

Webhook events are also sent from your repository to your "organization webhooks". more info.

These are set up in your github enterprise. They are specific to the version of the github enterprise. You may have no visibility because of your access limitations (developer, maintainer, admin, etc).

Current version: Help | Change Memory Settings:

Since IntelliJ IDEA 15.0.4 you can also use: Help | Edit Custom VM Options...:

This will automatically create a copy of the .vmoptions file in the config folder and open a dialog to edit it.

Older versions:

IntelliJ IDEA 12 is a signed application, therefore changing options in Info.plist is no longer recommended, as the signature will not match and you will get issues depending on your system security settings (app will either not run, or firewall will complain on every start, or the app will not be able to use the system keystore to save passwords).

As a result of addressing IDEA-94050 a new way to supply JVM options was introduced in IDEA 12:

Now it can take VM options from ~/Library/Preferences/<appFolder>/idea.vmoptions and system properties from ~/Library/Preferences/<appFolder>/idea.properties.

For example, to use -Xmx2048m option you should copy the original .vmoptions file from /Applications/IntelliJ IDEA.app/bin/idea.vmoptions to ~/Library/Preferences/IntelliJIdea12/idea.vmoptions, then modify the -Xmx setting.

The final file should look like:

-Xms128m
-Xmx2048m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=64m
-XX:+UseCodeCacheFlushing
-XX:+UseCompressedOops

Copying the original file is important, as options are not added, they are replaced.

This way your custom options will be preserved between updates and application files will remain unmodified making signature checker happy.

Community Edition: ~/Library/Preferences/IdeaIC12/idea.vmoptions file is used instead.

As PPK points out here, in IE you can also use

e.cancelBubble = true;

You can use the pkg_resources module from setuptools. For example:

import pkg_resources

package_name = 'cool_package'
try:
    cool_package_dist_info = pkg_resources.get_distribution(package_name)
except pkg_resources.DistributionNotFound:
    print('{} not installed'.format(package_name))
else:
    print(cool_package_dist_info)

Note that there is a difference between python module and a python package. A package can contain multiple modules and module's names might not match the package name.

The VBA script below looks for all unique values from cell B5 all the way down to the very last cell in column B… $B$1048576. Once it is found, they are stored in the array (objDict).

Private Const SHT_MASTER = “MASTER”
Private Const SHT_INST_INDEX = “InstrumentIndex”

Sub UniqueList()
    Dim Xyber
    Dim objDict As Object
    Dim lngRow As Long

    Sheets(SHT_MASTER).Activate
    Xyber = Application.Transpose(Sheets(SHT_MASTER).Range([b5], Cells(Rows.count, “B”).End(xlUp)))
    Sheets(SHT_INST_INDEX).Activate
    Set objDict = CreateObject(“Scripting.Dictionary”)
    For lngRow = 1 To UBound(Xyber, 1)
    If Len(Xyber(lngRow)) > 0 Then objDict(Xyber(lngRow)) = 1
    Next
    Sheets(SHT_INST_INDEX).Range(“B1:B” & objDict.count) = Application.Transpose(objDict.keys)
End Sub

I have tested and documented with some screenshots of the this solution. Here is the link where you can find it....

http://xybernetics.com/techtalk/excelvba-getarrayofuniquevaluesfromspecificcolumn/

An endpoint is a URL pattern used to communicate with an API.

Use a regular expression for .replace().:

messagetoSend = messagetoSend.replace(/\n/g, "<br />");

If those linebreaks were made by windows-encoding, you will also have to replace the carriage return.

messagetoSend = messagetoSend.replace(/\r\n/g, "<br />");

please try this,

$(document).ready(function(){
    $('#message').css({"color":"red","font-family":"verdana"});
})

Actually I got something like that on IE recently and it was related to JavaScript syntax "errors". I say error in quotes because it was fine everywhere but on IE. This was under IE6. The problem was related to JSON object creation and an extra comma, such as

{ one:1, two:2, three:3, }

IE6 really doesn't like that comma after 3. You might look for something like that, touchy little syntax formality issues.

Yeah, I thought the multi-million line number in my 25 line JavaScript was interesting too.

Good luck.

On a client-side react application, there are a couple of ways of rendering a prop as a string with some html. One safer than the other...

1 - Define the prop as jsx (my preference)

const someProps = {
  greeting: {<div>Hello<a href="/${name_profile}">${name_profile}</a></div>}
}


const GreetingComopnent = props => (
  <p>{props.someProps.greeting}</p>
)

• The only requirement here is that whatever file is generating this prop needs to include React as a dependency (in case you're generating the prop's jsx in a helper file etc).

2 - Dangerously set the innerHtml

const someProps = {
  greeting: '<React.Fragment>Hello<a href="/${name_profile}">${name_profile}</a></React.Fragment>'
}

const GreetingComponent = props => {
  const innerHtml = { __html: props.someProps.greeting }
  return <p dangerouslySetInnerHtml={innerHtml}></p>
}

• This second approach is discouraged. Imagine an input field whose input value is rendered as a prop in this component. A user could enter a script tag in the input and the component that renders this input would execute this potentially malicious code. As such, this approach has the potential to introduce cross-site scripting vulnerabilities. For more information, refer to the official React docs

By the way, to prevent this from happening in the first place, simply press Ctrl+C in terminal while SimpleHTTPServer is still running normally. This will "properly" stop the server and release the port so you don't have to find and kill the process again before restarting the server.

(Mods: I did try to put this comment on the best answer where it belongs, but I don't have enough reputation.)

The accepted answer will give a false positive if the input is a number plus text, because "stol" will convert the firsts digits and ignore the rest.

I like the following version the most, since it's a nice one-liner that doesn't need to define a function and you can just copy and paste wherever you need it.

#include <string>

...

std::string s;

bool has_only_digits = (s.find_first_not_of( "0123456789" ) == std::string::npos);

EDIT: if you like this implementation but you do want to use it as a function, then this should do:

bool has_only_digits(const string s){
  return s.find_first_not_of( "0123456789" ) == string::npos;
}

java.lang.System.currentTimeMillis(); will return the datetime since the epoch

There is a rule in Python programming called "it is Easier to Ask for Forgiveness than for Permission" (in short: EAFP). It means that you should catch exceptions instead of checking values for validity.

Thus, try the following:

try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except ValueError:  # includes simplejson.decoder.JSONDecodeError
    print 'Decoding JSON has failed'

EDIT: Since simplejson.decoder.JSONDecodeError actually inherits from ValueError (proof here), I simplified the catch statement by just using ValueError.

An important consideration for accessing mysql from a shell script used in cron, is that mysql looks at the logged in user to determine a .my.cnf to load.

That does not work with cron. It can also get confusing if you are using su/sudo as the logged in user might not be the user you are running as.

I use something like:

mysql --defaults-extra-file=/path/to/specific/.my.cnf -e 'SELECT something FROM sometable'

Just make sure that user and group ownership and permissions are set appropriately and tightly on the .my.cnf file.

For .NET Core 2.2 you can publish the application and set the target to be a self-contained executable.

In Visual Studio right click your console application project. Select publish to folder and set the profile settings like so:

You'll find your compiled code with the .exe in the publish folder.

There are certain common things between lock_guard and unique_lock and certain differences.

But in the context of the question asked, the compiler does not allow using a lock_guard in combination with a condition variable, because when a thread calls wait on a condition variable, the mutex gets unlocked automatically and when other thread/threads notify and the current thread is invoked (comes out of wait), the lock is re-acquired.

This phenomenon is against the principle of lock_guard. lock_guard can be constructed only once and destructed only once.

Hence lock_guard cannot be used in combination with a condition variable, but a unique_lock can be (because unique_lock can be locked and unlocked several times).

I wish MS SQL could also do something like COUNT(DISTINCT A, B). But it can't.

At first JayTee's answer seemed like a solution to me bu after some tests CHECKSUM() failed to create unique values. A quick example is, both CHECKSUM(31,467,519) and CHECKSUM(69,1120,823) gives the same answer which is 55.

Then I made some research and found that Microsoft does NOT recommend using CHECKSUM for change detection purposes. In some forums some suggested using

SELECT COUNT(DISTINCT CHECKSUM(value1, value2, ..., valueN) + CHECKSUM(valueN, value(N-1), ..., value1))

but this is also not conforting.

You can use HASHBYTES() function as suggested in TSQL CHECKSUM conundrum. However this also has a small chance of not returning unique results.

I would suggest using

SELECT COUNT(DISTINCT CAST(DocumentId AS VARCHAR)+'-'+CAST(DocumentSessionId AS VARCHAR)) FROM DocumentOutputItems

Use oracle.jdbc.OracleDriver, not oracle.jdbc.driver.OracleDriver. You do not need to register it if the driver jar file is in the "WEB-INF\lib" directory, if you are using Tomcat. Save this as test.jsp and put it in your web directory, and redeploy your web app folder in Tomcat manager:

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.

If you don't want to reinvent the wheel, you can install the symbolic maths library sympy (yes it's Python 3 compatible)

pip install sympy

And use the primerange function

from sympy import sieve
primes = list(sieve.primerange(1, 10**6))

You can use each()

$('#id-submit').click(function () {
      $(":input").each(function(){
          this.value = this.value.toUpperCase();          
      });
});

Along with JFileChooser is possible use this:

UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");

for have a Look and Feel like Windows.
