A matrix is really just a vector with a dim attribute (for the dimensions). So you can add dimensions to vec using the dim() function and vec will then be a matrix:

vec <- 1:49
dim(vec) <- c(7, 7)  ## (rows, cols)
vec

> vec <- 1:49
> dim(vec) <- c(7, 7)  ## (rows, cols)
> vec
     [,1] [,2] [,3] [,4] [,5] [,6] [,7]
[1,]    1    8   15   22   29   36   43
[2,]    2    9   16   23   30   37   44
[3,]    3   10   17   24   31   38   45
[4,]    4   11   18   25   32   39   46
[5,]    5   12   19   26   33   40   47
[6,]    6   13   20   27   34   41   48
[7,]    7   14   21   28   35   42   49

For those using bootstrap 4 beta you can add max-width on your navbar link to have control on the size of your logo with img-fluid class on the image element.

 <a class="navbar-brand" href="#" style="max-width: 30%;">
    <img src="images/logo.png" class="img-fluid">
 </a>

you can use document.document.querySelectorAll("#divId")

<input type="checkbox" name="check1" value="checkbox" onchange="showMe('div1')" /> checkbox

<div id="div1" style="display:none;">NOTICE</div>

  <script type="text/javascript">
<!--
   function showMe (box) {
    var chboxs = document.getElementById("div1").style.display;
    var vis = "none";
        if(chboxs=="none"){
         vis = "block"; }
        if(chboxs=="block"){
         vis = "none"; }
    document.getElementById(box).style.display = vis;
}
  //-->
</script>

It should be made crystal clear because at the moment it isn't. There is a modified and compiled version of SendSignal to send Ctrl-C (by default it only sends Ctrl+Break). Here are some binaries:

(2014-3-7) : I built both 32-bit and 64-bit version with Ctrl-C, it's called SendSignalCtrlC.exe and you can download it at: https://dl.dropboxusercontent.com/u/49065779/sendsignalctrlc/x86/SendSignalCtrlC.exe https://dl.dropboxusercontent.com/u/49065779/sendsignalctrlc/x86_64/SendSignalCtrlC.exe -- Juraj Michalak

I have also mirrored those files just in case:
32-bit version: https://www.dropbox.com/s/r96jxglhkm4sjz2/SendSignalCtrlC.exe?dl=0
64-bit version: https://www.dropbox.com/s/hhe0io7mcgcle1c/SendSignalCtrlC64.exe?dl=0

Disclaimer: I didn't build those files. No modification was made to the compiled original files. The only platform tested is the 64-bit Windows 7. It is recommended to adapt the source available at http://www.latenighthacking.com/projects/2003/sendSignal/ and compile it yourself.

The question is for linux but I had the same issue with git bash on my Windows machine.

My pqsql is installed here: C:\Program Files\PostgreSQL\10\bin\psql.exe

You can add the location of psql.exe to your Path environment variable as shown in this screenshot:

After changing the above, please close all cmd and/or bash windows, and re-open them (as mentioned in the comments @Ayush Shankar)

You might need to change default logging user using below command.

psql -U postgres

Here postgres is the username. Without -U, it will pick the windows loggedin user.

As of November 30, 2020, AWS now has EC2 Mac instances:

• https://aws.amazon.com/ec2/instance-types/mac/

We previously used and had good experiences with:

• https://MacStadium.com/

Here are some other sites that I am aware of:

• https://flow.swiss/
• https://hostmyapple.com/ (We used them a long time ago, before MacStadium)

When we were with MacStadium, we loved them. We had great connectivity/uptime. When I've needed hands-on support to plug in a Time Machine backup, they've been great. They performed a seamless upgrade to better hardware for us over one weekend (when we could afford a bit of downtime), and that went off without a hitch. Highly recommended. (Not affiliated - just happy).

In April of 2020, we stopped using MacStadium, simply because we no longer needed a Mac server. If I need another Mac host, I would be happy to go back to them.

If you're using (or are happy to use) Apache Commons Collections, you can use CollectionUtils.isEqualCollection which "returns true iff the given Collections contain exactly the same elements with exactly the same cardinalities."

Subtracting the Minimum of the ends of the ranges from the Maximum of the beginning seems to do the trick. If the result is less than or equal to zero, we have an overlap. This visualizes it well:

You probably haven't installed GLUT:

1. Install GLUT If you do not have GLUT installed on your machine you can download it from: http://www.xmission.com/~nate/glut/glut-3.7.6-bin.zip (or whatever version) GLUT Libraries and header files are • glut32.lib • glut.h

Source: http://cacs.usc.edu/education/cs596/OGL_Setup.pdf

EDIT:

The quickest way is to download the latest header, and compiled DLLs for it, place it in your system32 folder or reference it in your project. Version 3.7 (latest as of this post) is here: http://www.opengl.org/resources/libraries/glut/glutdlls37beta.zip

Folder references:

glut.h: 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\GL\'
glut32.lib: 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib\'
glut32.dll: 'C:\Windows\System32\'

For 64-bit machines, you will want to do this.
glut32.dll: 'C:\Windows\SysWOW64\'

Same pattern applies to freeglut and GLEW files with the header files in the GL folder, lib in the lib folder, and dll in the System32 (and SysWOW64) folder.
1. Under Visual C++, select Empty Project.
2. Go to Project -> Properties. Select Linker -> Input then add the following to the Additional Dependencies field:
opengl32.lib
glu32.lib
glut32.lib

A warning about the Jquery Caret plugin.

It will conflict with the Masked Input plugin (or vice versa). Fortunately the Masked Input plugin includes a caret() function of its own, which you can use very similarly to the Caret plugin for your basic needs - $(element).caret().begin or .end

Use String.substring(beginIndex, endIndex)

str.substring(0, str.length() - 2);

The substring begins at the specified beginIndex and extends to the character at index (endIndex - 1)

To answer more precisely to the question:

conda (which is conda for miniconda as for Anaconda) updates all but ONLY within a specific version of a package -> major and minor. That's the paradigm.

In the documentation you will find "NOTE: Conda updates to the highest version in its series, so Python 2.7 updates to the highest available in the 2.x series and 3.6 updates to the highest available in the 3.x series." doc

If Wang does not gives a reproducible example, one can only assist. e.g. is it really the virtual environment he wants to update or could Wang get what he/she wants with

conda update -n ENVIRONMENT --all

*PLEASE read the docs before executing "update --all"! This does not lead to an update of all packages by nature. Because conda tries to resolve the relationship of dependencies between all packages in your environment, this can lead to DOWNGRADED packages without warnings.

If you only want to update almost all, you can create a pin file

echo "conda ==4.0.0" >> ~/miniconda3/envs/py35/conda-meta/pinned
echo "numpy 1.7.*" >> ~/miniconda3/envs/py35/conda-meta/pinned

before running the update. conda issues not pinned

If later on you want to ignore the file in your env for an update, you can do:

conda update --all --no-pin

You should not do update --all. If you need it nevertheless you are saver to test this in a cloned environment.

First step should always be to backup your current specification:

conda list -n py35 --explicit 

(but even so there is not always a link to the source available - like for jupyterlab extensions)

Next you can clone and update:

conda create -n py356 --clone py35

conda activate py356
conda config --set pip_interop_enabled True # for conda>=4.6
conda update --all

conda config

update:

Because the idea of conda is nice but it is not working out very well for complex environments I personally prefer the combination of nix-shell (or lorri) and poetry [as superior pip/conda .-)] (intro poetry2nix).

Alternatively you can use nix and mach-nix (where you only need you requirements file. It resolves and builds environments best.

On Linux / macOS you could use nix like

nix-env -iA nixpkgs.python37

to enter an environment that has e.g. in this case Python3.7 (for sure you can change the version)

or as a very good Python (advanced) environment you can use mach-nix (with nix) like

mach-nix env ./env -r requirements.txt 

(which even supports conda [but currently in beta])

or via api like

nix-shell -p nixFlakes --run "nix run github:davhau/mach-nix#with.ipython.pandas.seaborn.bokeh.scikit-learn "

Finally if you really need to work with packages that are not compatible due to its dependencies, it is possible with technologies like NixOS/nix-pkgs.

The most important thing to do when solving a Technical Test is Don't use shortcut methods -- they want to see how you think algorithmically! Not your use of methods.

Here is one that I came up with (45 minutes after I blew the test). There are a couple optimizations to make though. When writing any algorithm, its best to assume false and alter the logic if its looking to be true.

isPalindrome():

Basically, to make this run in O(N) (linear) complexity you want to have 2 iterators whose vectors point towards each other. Meaning, one iterator that starts at the beginning and one that starts at the end, each traveling inward. You could have the iterators traverse the whole array and use a condition to break/return once they meet in the middle, but it may save some work to only give each iterator a half-length by default.

for loops seem to force the use of more checks, so I used while loops - which I'm less comfortable with.

Here's the code:

/**
 * TODO: If func counts out, let it return 0
 *  * Assume !isPalindrome (invert logic)
 */
function isPalindrome(S){
    var s = S
      , len = s.length
      , mid = len/2;
      , i = 0, j = len-1;

    while(i<mid){
        var l = s.charAt(i);
        while(j>=mid){
            var r = s.charAt(j);
            if(l === r){
                console.log('@while *', i, l, '...', j, r);
                --j;
                break;
            }
            console.log('@while !', i, l, '...', j, r);
            return 0;
        }
        ++i;
    }
    return 1;
}

var nooe = solution('neveroddoreven');  // even char length
var kayak = solution('kayak');  // odd char length
var kayaks = solution('kayaks');

console.log('@isPalindrome', nooe, kayak, kayaks);

Notice that if the loops count out, it returns true. All the logic should be inverted so that it by default returns false. I also used one short cut method String.prototype.charAt(n), but I felt OK with this as every language natively supports this method.

To answer the question as asked (without repeating unduly what appears in other answers)

Lexers and parsers are not very different, as suggested by the accepted answer. Both are based on simple language formalisms: regular languages for lexers and, almost always, context-free (CF) languages for parsers. They both are associated with fairly simple computational models, the finite state automaton and the push-down stack automaton. Regular languages are a special case of context-free languages, so that lexers could be produced with the somewhat more complex CF technology. But it is not a good idea for at least two reasons.

A fundamental point in programming is that a system component should be buit with the most appropriate technology, so that it is easy to produce, to understand and to maintain. The technology should not be overkill (using techniques much more complex and costly than needed), nor should it be at the limit of its power, thus requiring technical contortions to achieve the desired goal.

That is why "It seems fashionable to hate regular expressions". Though they can do a lot, they sometimes require very unreadable coding to achieve it, not to mention the fact that various extensions and restrictions in implementation somewhat reduce their theoretical simplicity. Lexers do not usually do that, and are usually a simple, efficient, and appropriate technology to parse token. Using CF parsers for token would be overkill, though it is possible.

Another reason not to use CF formalism for lexers is that it might then be tempting to use the full CF power. But that might raise sructural problems regarding the reading of programs.

Fundamentally, most of the structure of program text, from which meaning is extracted, is a tree structure. It expresses how the parse sentence (program) is generated from syntax rules. Semantics is derived by compositional techniques (homomorphism for the mathematically oriented) from the way syntax rules are composed to build the parse tree. Hence the tree structure is essential. The fact that tokens are identified with a regular set based lexer does not change the situation, because CF composed with regular still gives CF (I am speaking very loosely about regular transducers, that transform a stream of characters into a stream of token).

However, CF composed with CF (via CF transducers ... sorry for the math), does not necessarily give CF, and might makes things more general, but less tractable in practice. So CF is not the appropriate tool for lexers, even though it can be used.

One of the major differences between regular and CF is that regular languages (and transducers) compose very well with almost any formalism in various ways, while CF languages (and transducers) do not, not even with themselves (with a few exceptions).

(Note that regular transducers may have others uses, such as formalization of some syntax error handling techniques.)

BNF is just a specific syntax for presenting CF grammars.

EBNF is a syntactic sugar for BNF, using the facilities of regular notation to give terser version of BNF grammars. It can always be transformed into an equivalent pure BNF.

However, the regular notation is often used in EBNF only to emphasize these parts of the syntax that correspond to the structure of lexical elements, and should be recognized with the lexer, while the rest with be rather presented in straight BNF. But it is not an absolute rule.

To summarize, the simpler structure of token is better analyzed with the simpler technology of regular languages, while the tree oriented structure of the language (of program syntax) is better handled by CF grammars.

I would suggest also looking at AHR's answer.

But this leaves a question open: Why trees?

Trees are a good basis for specifying syntax because

• they give a simple structure to the text

• there are very convenient for associating semantics with the text on the basis of that structure, with a mathematically well understood technology (compositionality via homomorphisms), as indicated above. It is a fundamental algebraic tool to define the semantics of mathematical formalisms.

Hence it is a good intermediate representation, as shown by the success of Abstract Syntax Trees (AST). Note that AST are often different from parse tree because the parsing technology used by many professionals (Such as LL or LR) applies only to a subset of CF grammars, thus forcing grammatical distorsions which are later corrected in AST. This can be avoided with more general parsing technology (based on dynamic programming) that accepts any CF grammar.

Statement about the fact that programming languages are context-sensitive (CS) rather than CF are arbitrary and disputable.

The problem is that the separation of syntax and semantics is arbitrary. Checking declarations or type agreement may be seen as either part of syntax, or part of semantics. The same would be true of gender and number agreement in natural languages. But there are natural languages where plural agreement depends on the actual semantic meaning of words, so that it does not fit well with syntax.

Many definitions of programming languages in denotational semantics place declarations and type checking in the semantics. So stating as done by Ira Baxter that CF parsers are being hacked to get a context sensitivity required by syntax is at best an arbitrary view of the situation. It may be organized as a hack in some compilers, but it does not have to be.

Also it is not just that CS parsers (in the sense used in other answers here) are hard to build, and less efficient. They are are also inadequate to express perspicuously the kinf of context-sensitivity that might be needed. And they do not naturally produce a syntactic structure (such as parse-trees) that is convenient to derive the semantics of the program, i.e. to generate the compiled code.

ACE.oledb.16.0 dosen't work in the 64-bit os

download patch from https://www.microsoft.com/en-us/download/details.aspx?id=13255

I mashed up a few answers.

Use an ivar that gets initialized during viewDidLoad:

UIGestureRecognizer *tapper;

- (void)viewDidLoad
{
    [super viewDidLoad];
    tapper = [[UITapGestureRecognizer alloc]
                initWithTarget:self action:@selector(handleSingleTap:)];
    tapper.cancelsTouchesInView = NO;
    [self.view addGestureRecognizer:tapper];
}

Dismiss what ever is currently editing:

- (void)handleSingleTap:(UITapGestureRecognizer *) sender
{
    [self.view endEditing:YES];
}

The first statement depends on the context in which it is declared.

If it is declared in the global context it will create an implied global variable called "foo" which will be a variable which points to the function. Thus the function call "foo()" can be made anywhere in your javascript program.

If the function is created in a closure it will create an implied local variable called "foo" which you can then use to invoke the function inside the closure with "foo()"

EDIT:

I should have also said that function statements (The first one) are parsed before function expressions (The other 2). This means that if you declare the function at the bottom of your script you will still be able to use it at the top. Function expressions only get evaluated as they are hit by the executing code.

END EDIT

Statements 2 & 3 are pretty much equivalent to each other. Again if used in the global context they will create global variables and if used within a closure will create local variables. However it is worth noting that statement 3 will ignore the function name, so esentially you could call the function anything. Therefore

var foo = function foo() { return 5; }

Is the same as

var foo = function fooYou() { return 5; }

Cava Packager is great on the Windows ecosystem.

How about a following approach for 9 slots? Declare 9 integer variables for a 3x3 matrix (a1,a2....a9) where a1,a2,a3 represent row-1 and a1,a4,a7 would form column-1 (you get the idea). Use '1' to indicate Player-1 and '2' to indicate Player-2.

There are 8 possible win combinations: Win-1: a1+a2+a3 (answer could be 3 or 6 based on which player won) Win-2: a4+a5+a6 Win-3: a7+a8+a9 Win-4: a1+a4+a7 .... Win-7: a1+a5+a9 Win-8: a3+a5+a7

Now we know that if player one crosses a1 then we need to reevaluate sum of 3 variables: Win-1, Win-4 and Win-7. Whichever 'Win-?' variables reaches 3 or 6 first wins the game. If Win-1 variable reaches 6 first then Player-2 wins.

I do understand that this solution is not scalable easily.

Extra instructions when following @Luke-West's + @Vaiden's solutions:

• If your scheme has not changed (still showing my mac) on the top left next to the stop button:

1. Click NEWLY created Project name (next to stop button) > Click Edit Schemes > Build (left hand side) > Remove the old target (will say it's missing) and replace with the NEWLY named project under NEWLY named project logo

Also, I did not have to use step 3 of @Vaiden's solution. Just running rm -rf Pods/ in terminal got rid of all old pod files

I also did not have to use step 9 in @Vaiden's solution, instead I just removed the OLD project named framework under Link Binary Libraries (the NEWLY named framework was already there)

So the updated steps would be as follows:

Step 1 - Rename the project

0. If you are using cocoapods in your project, close the workspace, and open the XCode project for these steps.
1. Click on the project you want to rename in the "Project navigator" on the left of the Xcode view.
2. On the right select the "File inspector" and the name of your project should be in there under "Identity and Type", change it to the new name.
3. Click "Rename" in a dropdown menu

Step 2 - Rename the Scheme

1. In the top bar (near "Stop" button), there is a scheme for your OLD product, click on it, then go to "Manage schemes"
2. Click on the OLD name in the scheme, and it will become editable, change the name
3. Quit XCode.
4. In the master folder, rename OLD.xcworkspace to NEW.xcworkspace.

Step 3 - Rename the folder with your assets

1. Quit Xcode
2. In the correctly named master folder, there is a newly named xcodeproj file with the the wrongly named OLD folder. Rename the OLD folder to your new name
3. Reopen the project, you will see a warning: "The folder OLD does not exist", dismiss the warning
4. In the "Project navigator" on the left, click the top level OLD folder name
5. In Utilities pane under "Identity and type" you will see the "Name" entry, change this from the OLD to the new name
6. Just below there is a "Location" entry. Click on a folder with the OLD name and chose the newly renamed folder

Step 4 - Rename the Build plist data

1. Click on the project in the "Project navigator" on the left, in the main panel select "Build Settings"
2. Search for "plist" in this section Under packaging, you will see Info.plist, and Product bundle identifier
3. Rename the top entry in Info.plist
4. Do the same for Product Identifier

Step 5 Handling Podfile

1. In XCode: choose and edit Podfile from the project navigator. You should see a target clause with the OLD name. Change it to NEW.
2. Quit XCode.
3. In terminal, cd into project directory, then: pod deintegrate
4. Run pod install.
5. Open XCode.
6. Click on your project name in the project navigator.
7. In the main pane, switch to the Build Phases tab. Under Link Binary With Libraries, look for the OLD framework and remove it (should say it is missing) The NEWLY named framework should already be there, if not use the "+" button at the bottom of the window to add it
8. If you have an objective-c Bridging header go to Build settings and change the location of the header from OLD/OLD-Bridging-Header.h to NEW/NEW-Bridging-Header.h
9. Clean and run.

You should be able to build with no errors after you have followed all of the steps successfully

An alternative method is to use a Grid with one column and n rows. Set all the rows heights to Auto, and the bottom-most row height to 1*.

I prefer this method because I've found Grids have better layout performance than DockPanels, StackPanels, and WrapPanels. But unless you're using them in an ItemTemplate (where the layout is being performed for a large number of items), you'll probably never notice.

For me just ${workspace} worked without even initializing the variable 'workspace.'

^ outside of the character class ("[a-zA-Z]") notes that it is the "begins with" operator.
^ inside of the character negates the specified class.

So, "^[a-zA-Z]" translates to "begins with character from a-z or A-Z", and "[^a-zA-Z]" translates to "is not either a-z or A-Z"

Here's a quick reference: http://www.regular-expressions.info/reference.html

this will do the trick for you

if (!!val) {
    alert("this is not null")
} else {
    alert("this is null")
}

you just open command prompt, then enter in c:/>('cd../../') then npm install -g cordova

You could use loop.index:

{% for i in p %}
  {{ loop.index }}
{% endfor %}

Check the template designer documentation.

In more recent versions, due to scoping rules, the following would not work:

{% set count = 1 %}
{% for i in p %}
  {{ count }}
  {% set count = count + 1 %}
{% endfor %}

Way 1: only works for dataURL, not for other types of url.

function dataURLtoFile(dataurl, filename) {
    var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],
        bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);
    while(n--){
        u8arr[n] = bstr.charCodeAt(n);
    }
    return new File([u8arr], filename, {type:mime});
}

//Usage example:
var file = dataURLtoFile('data:image/png;base64,......', 'a.png');
console.log(file);

Way 2: works for any type of url, (http url, dataURL, blobURL, etc...)

//return a promise that resolves with a File instance
function urltoFile(url, filename, mimeType){
    mimeType = mimeType || (url.match(/^data:([^;]+);/)||'')[1];
    return (fetch(url)
        .then(function(res){return res.arrayBuffer();})
        .then(function(buf){return new File([buf], filename, {type:mimeType});})
    );
}

//Usage example:
urltoFile('data:image/png;base64,......', 'a.png')
.then(function(file){
    console.log(file);
})

Both works in Chrome and Firefox.

Concise if you are just interested in the time elapsed that is under 24 hours. You can format the output as needed in the return statement :

import datetime
def elapsed_interval(start,end):
    elapsed = end - start
    min,secs=divmod(elapsed.days * 86400 + elapsed.seconds, 60)
    hour, minutes = divmod(min, 60)
    return '%.2d:%.2d:%.2d' % (hour,minutes,secs)

if __name__ == '__main__':
    time_start=datetime.datetime.now()
    """ do your process """
    time_end=datetime.datetime.now()
    total_time=elapsed_interval(time_start,time_end)

Don't use firefox profile and try below code:

driver.get("http://UserName:[email protected]");

If you're implementing it in IE browser, there are certain things which you need to do.

In case your authentication server requires username with domain like "domainuser" you need to add double slash / to the url:

//localdomain\user:[email protected]

This code is working for blur effect for all browsers.

filter: blur(10px);
-webkit-filter: blur(10px);
-moz-filter: blur(10px);
-o-filter: blur(10px);
-ms-filter: blur(10px);

Change the last line to

q + theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust=1))

By default, the axes are aligned at the center of the text, even when rotated. When you rotate +/- 90 degrees, you usually want it to be aligned at the edge instead:

I'm new to shell scripting too, but I had this same issue. Make sure at the end of your script you have a blank line. Otherwise it won't work.

Such unexpected problems can appear when you copy the code from a web page or email and the text contains unprintable characters like individual CR or LF and non-breaking spaces.

 
            string[] result = new string[table.Columns.Count];
            DataRow dr = table.Rows[0];
            for (int i = 0; i < dr.ItemArray.Length; i++)
            {
                result[i] = dr[i].ToString();
            }
            foreach (string str in result)
                Console.WriteLine(str);

Standard zip files normally use the deflate algorithm.

To extract files without using third party libraries use DeflateStream. You'll need a bit more information about the zip file archive format as Microsoft only provides the compression algorithm.

You may also try using zipfldr.dll. It is Microsoft's compression library (compressed folders from the Send to menu). It appears to be a com library but it's undocumented. You may be able to get it working for you through experimentation.

I'm also running XP SP2, and this works perfectly (from the command line...):

Look out for a double opening bracket syntax error as well {{ which can cause this error message to appear

From a Java Game Engine:

/**
 * Converts a given Image into a BufferedImage
 *
 * @param img The Image to be converted
 * @return The converted BufferedImage
 */
public static BufferedImage toBufferedImage(Image img)
{
    if (img instanceof BufferedImage)
    {
        return (BufferedImage) img;
    }

    // Create a buffered image with transparency
    BufferedImage bimage = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB);

    // Draw the image on to the buffered image
    Graphics2D bGr = bimage.createGraphics();
    bGr.drawImage(img, 0, 0, null);
    bGr.dispose();

    // Return the buffered image
    return bimage;
}

I had everything set up, but still couldn't see proper error pages for status code 500 on our staging server, despite the fact everything worked fine on local development servers.

I found this blog post from Rick Strahl that helped me.

I needed to add Response.TrySkipIisCustomErrors = true; to my custom error handling code.

openssl x509 -outform der -in your-cert.pem -out your-cert.crt

rbind.fill from the package plyr might be what you are looking for.

You should never use a break statement to exit a loop. Of course you can do it, but that doesn't mean you should. It just isn't good programming practice. The more elegant way to exit is the following:

while(choice!=99)
{
    cin>>choice;
    if (choice==99)
        //exit here and don't get additional input
    else
       cin>>gNum;
}

if choice is 99 there is nothing else to do and the loop terminates.

I use macros defined in a header file to handle bit set and clear:

/* a=target variable, b=bit number to act upon 0-n */
#define BIT_SET(a,b) ((a) |= (1ULL<<(b)))
#define BIT_CLEAR(a,b) ((a) &= ~(1ULL<<(b)))
#define BIT_FLIP(a,b) ((a) ^= (1ULL<<(b)))
#define BIT_CHECK(a,b) (!!((a) & (1ULL<<(b))))        // '!!' to make sure this returns 0 or 1

/* x=target variable, y=mask */
#define BITMASK_SET(x,y) ((x) |= (y))
#define BITMASK_CLEAR(x,y) ((x) &= (~(y)))
#define BITMASK_FLIP(x,y) ((x) ^= (y))
#define BITMASK_CHECK_ALL(x,y) (!(~(x) & (y)))
#define BITMASK_CHECK_ANY(x,y) ((x) & (y))

There are two solutions posted on that page. The one with lower votes I would recommend if possible.

If you are using HTML5 then it is perfectly valid to put a div inside of a. As long as the div doesn't also contain some other specific elements like other link tags.

<a href="Music.html">
  <div id="music" class="nav">
    Music I Like
  </div>
</a>

The solution you are confused about actually makes the link as big as its container div. To make it work in your example you just need to add position: relative to your div. You also have a small syntax error which is that you have given the span a class instead of an id. You also need to put your span inside the link because that is what the user is clicking on. I don't think you need the z-index at all from that example.

div { position: relative; }
.hyperspan {
    position:absolute;
    width:100%;
    height:100%;
    left:0;
    top:0;
}

<div id="music" class="nav">Music I Like 
    <a href="http://www.google.com"> 
        <span class="hyperspan"></span>
    </a>   
</div>

http://jsfiddle.net/rBKXM/9

When you give absolute positioning to an element it bases its location and size after the first parent it finds that is relatively positioned. If none, then it uses the document. By adding relative to the parent div you tell the span to only be as big as that.

i had a diffrent approach, this might help someone in the future:

the customer wanted a page where you can swap languages. i needed to format numbers by that setting (not the browser setting / not by any predefined setting)

so i set an initial setting depending on the config settings (i18n)

$clang = $this->Session->read('Config.language');
echo "<script type='text/javascript'>var clang = '$clang'</script>";

later in the script i used a function to determine what numberformating i need

function getLangsettings(){
  if(typeof clang === 'undefined') clang = navigator.language;
  //console.log(clang);
  switch(clang){
    case 'de':
    case 'de-de':
        return {precision : 2, thousand : ".", decimal : ","}
    case 'en':
    case 'en-gb':
    default:
        return {precision : 2, thousand : ",", decimal : "."}
  }
}

so i used the set language of the page and as a fallback i used the browser settings.

which should be helpfull for testing purposes aswell.

depending on your customers you might not need that settings.

Convert the string to an integer base 16 then to hexadecimal.

print hex(int(string, base=16))

These are built-in functions.

http://docs.python.org/2/library/functions.html#int

Example

>>> string = 'AA'
>>> _int = int(string, base=16)
>>> _hex = hex(_int)
>>> print _int
170
>>> print _hex
0xaa
>>> 

Use any examples that don't insert each element one at a time, one insertion is most efficient

 $('.element').html( '<span>' + array.join('</span><span>')+'</span>');

The below statements show how to open/reopen Modal without using bootstrap.

Add two classes in css

And then use the below jQuery to reopen the modal if it is closed.

.hide_block
 {
   display:none  !important;
 }

 .display_block
 {
    display:block !important;
 } 

 $("#Modal").removeClass('hide_block');
 $("#Modal").addClass('display_block');
 $("Modal").show("slow");

It worked fine for me :)

If you run docker run <NAME> it will spawn a new image, which most likely isn't what you want.

If you want to change a current image do the following:

docker ps -a

Take the id of your target container and go to:

cd /var/lib/docker/containers/<conainerID><and then some:)>

Stop the container:

docker stop <NAME>

Change the files

vi config.v2.json

"Config": {
    ....
    "ExposedPorts": {
        "80/tcp": {},
        "8888/tcp": {}
    },
    ....
},
"NetworkSettings": {
....
"Ports": {
     "80/tcp": [
         {
             "HostIp": "",
             "HostPort": "80"
         }
     ],

And change file

vi hostconfig.json

"PortBindings": {
     "80/tcp": [
         {
             "HostIp": "",
             "HostPort": "80"
         }
     ],
     "8888/tcp": [
         {
             "HostIp": "",
             "HostPort": "8888"
         } 
     ]
 }

Restart your docker and it should work.

you may also try full xpath, I had a similar issue where I had to click on an element which has a property javascript onclick function. the full xpath method worked and no interactable exception was thrown.

One thing that you'll want to watch out for (it's a stupid mistake on my part, but it happens), is that the email address attached to the CSR needs to be the same as the email connected to your Apple Dev account. Once I used a new CSR and rebuilt all the certs and provisioning profiles, all was well in applesville.

I believe DB Designer does something like that. And I think they even have a free version.

edit Never mind. Michael's link is much better.

the "title" attribute will be used as the text for tooltip by the browser, if you want to apply style to it consider using some plugins

You could use the round function. If you use no second parameter (# of significant digits) then I think you will get the behavior you want.

IDLE output.

>>> round(2.99999999999)
3
>>> round(2.6)
3
>>> round(2.5)
3
>>> round(2.4)
2

As well as @Pablo's answer, for newer versions you can also use the asp-page-handler tag helper.

In the page:

<button asp-page-handler="Action1" type="submit">Action 1</button>
<button asp-page-handler="Action2" type="submit">Action 2</button>

then in the controller:

    public async Task OnPostAction1Async() {...}
    public async Task OnPostAction2Async() {...}

There is another the error happening which related to the order when calling initializing global variables. I've had the sample of code has similar error FailedPreconditionError (see above for traceback): Attempting to use uninitialized value W

def linear(X, n_input, n_output, activation = None):
    W = tf.Variable(tf.random_normal([n_input, n_output], stddev=0.1), name='W')
    b = tf.Variable(tf.constant(0, dtype=tf.float32, shape=[n_output]), name='b')
    if activation != None:
        h = tf.nn.tanh(tf.add(tf.matmul(X, W),b), name='h')
    else:
        h = tf.add(tf.matmul(X, W),b, name='h')
    return h

from tensorflow.python.framework import ops
ops.reset_default_graph()
g = tf.get_default_graph()
print([op.name for op in g.get_operations()])
with tf.Session() as sess:
    # RUN INIT
    sess.run(tf.global_variables_initializer())
    # But W hasn't in the graph yet so not know to initialize 
    # EVAL then error
    print(linear(np.array([[1.0,2.0,3.0]]).astype(np.float32), 3, 3).eval())

You should change to following

from tensorflow.python.framework import ops
ops.reset_default_graph()
g = tf.get_default_graph()
print([op.name for op in g.get_operations()])
with tf.Session() as 
    # NOT RUNNING BUT ASSIGN
    l = linear(np.array([[1.0,2.0,3.0]]).astype(np.float32), 3, 3)
    # RUN INIT
    sess.run(tf.global_variables_initializer())
    print([op.name for op in g.get_operations()])
    # ONLY EVAL AFTER INIT
    print(l.eval(session=sess))

In MySQL InnoDB, there are two types of index.

1. Primary key which is called clustered index. Index key words are stored with real record data in the B+Tree leaf node.

2. Secondary key which is non clustered index. These index only store primary key's key words along with their own index key words in the B+Tree leaf node. So when searching from secondary index, it will first find its primary key index key words and scan the primary key B+Tree to find the real data records. This will make secondary index slower compared to primary index search. However, if the select columns are all in the secondary index, then no need to look up primary index B+Tree again. This is called covering index.

Check to make sure there is a film release date; if the date is missing you will not be able to format on a non-object.

if ($info['Film_Release']){ //check if the date exists
   $dateFromDB = $info['Film_Release'];
   $newDate = DateTime::createFromFormat("l dS F Y", $dateFromDB);
   $newDate = $newDate->format('d/m/Y'); 
} else {
   $newDate = "none"; 
}

or

 $newDate = ($info['Film_Release']) ? DateTime::createFromFormat("l dS F Y", $info['Film_Release'])->format('d/m/Y'): "none" 

If you want to directly get the package name of the current app in focus, use this adb command -

adb shell dumpsys window windows | grep -E 'mFocusedApp'| cut -d / -f 1 | cut -d " " -f 7

Extra info from the result of the adb command is removed using the cut command. Original solution from here.

"_blank" is not guaranteed to be a new tab or window. It's implemented differently per-browser.

You can, however, put anything into target. I usually just say "_tab", and every browser I know of just opens it in a new tab.

Be aware that it means it's a named target, so if you try to open 2 URLs, they will use the same tab.

If you haven't committed changes

If your changes are compatible with the other branch

This is the case from the question because the OP wants to commit to a new branch and also applies if your changes are compatible with the target branch without triggering an overwrite.

As in the accepted answer by John Brodie, you can simply checkout the new branch and commit the work:

git checkout -b branch_name
git add <files>
git commit -m "message"

If your changes are incompatible with the other branch

If you get the error:

error: Your local changes to the following files would be overwritten by checkout:
...
Please commit your changes or stash them before you switch branches

Then you can stash your work, create a new branch, then pop your stash changes, and resolve the conflicts:

git stash
git checkout -b branch_name
git stash pop

It will be as if you had made those changes after creating the new branch. Then you can commit as usual:

git add <files>
git commit -m "message"

If you have committed changes

If you want to keep the commits in the original branch

See the answer by Carl Norum with cherry-picking, which is the right tool in this case:

git checkout <target name>
git cherry-pick <original branch>

If you don't want to keep the commits in the original branch

See the answer by joeytwiddle on this potential duplicate. Follow any of the above steps as appropriate, then roll back the original branch:

git branch -f <original branch> <earlier commit id>

If you have pushed your changes to a shared remote like GitHub, you should not attempt this roll-back unless you know what you are doing.

Here is what I use.

First day of the month:

date('Y-m-01');

Last day of the month:

date('Y-m-t');

If you only need to merge a particular directory and leave everything else intact and yet preserve history, you could possibly try this... create a new target-branch off of the master before you experiment.

The steps below assume you have two branches target-branch and source-branch, and the directory dir-to-merge that you want to merge is in the source-branch. Also assume you have other directories like dir-to-retain in the target that you don't want to change and retain history. Also, assumes there are merge conflicts in the dir-to-merge.

git checkout target-branch
git merge --no-ff --no-commit -X theirs source-branch
# the option "-X theirs", will pick theirs when there is a conflict. 
# the options "--no--ff --no-commit" prevent a commit after a merge, and give you an opportunity to fix other directories you want to retain, before you commit this merge.

# the above, would have messed up the other directories that you want to retain.
# so you need to reset them for every directory that you want to retain.
git reset HEAD dir-to-retain
# verify everything and commit.

Since the FragmentManager will take care of restoring your Fragments for you as soon as the onResume() method is called I have the fragment call out to the activity and add itself to a list. In my instance I am storing all of this in my PagerAdapter implementation. Each fragment knows it's position because it is added to the fragment arguments on creation. Now whenever I need to manipulate a fragment at a specific index all I have to do is use the list from my adapter.

The following is an example of an Adapter for a custom ViewPager that will grow the fragment as it moves into focus, and scale it down as it moves out of focus. Besides the Adapter and Fragment classes I have here all you need is for the parent activity to be able to reference the adapter variable and you are set.

Am I missing something ?

If you can't set visibility on TemplateField then set it on its content

<asp:TemplateField>
  <ItemTemplate>
    <asp:LinkButton Visible='<%# MyBoolProperty %>' ID="foo" runat="server" ... />
  </ItemTemplate>
</asp:TemplateField> 

or if your content is complex then enclose it into a div and set visibility on the div

<asp:TemplateField>
  <ItemTemplate>
    <div runat="server" visible='<%# MyBoolProperty  %>' >
      <asp:LinkButton ID="attachmentButton" runat="server" ... />
    </div>
  </ItemTemplate>
</asp:TemplateField> 

I think you are asking about code like this.

int  count = (request.getParameter("counter") == null) ? 0 : Integer.parseInt(request.getParameter("counter"));

delete will only delete current object record from db but not its associated children records from db.

destroy will delete current object record from db and also its associated children record from db.

Their use really matters:

If your multiple parent objects share common children objects, then calling destroy on specific parent object will delete children objects which are shared among other multiple parents.

Use something like

ALTER TABLE T2
ADD CONSTRAINT fk_employee
FOREIGN KEY (employeeID)
REFERENCES T1 (employeeID)
ON DELETE CASCADE;

Fill in the correct column names and you should be set. As mark_s correctly stated, if you have already a foreign key constraint in place, you maybe need to delete the old one first and then create the new one.

Try removing the last / at the end of the directory path to exclude

tar -pczf MyBackup.tar.gz /home/user/public_html/ --exclude "/home/user/public_html/tmp" 

we can use javascript's FileReader() and it's readAsDataURL(fileContent) function to show local drive/folder file. Bind change event to image then call javascript's showpreview function. Try this -

<!doctype html>
<html>

<head>
    <meta charset='utf-8'>
    <meta name='viewport' content='width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=no;'>
    <meta http-equiv='Content-Type' content='text/html; charset=utf-8'>
    <title></title>

    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

    <script type="text/javascript">
    function showpreview(e) {
        var reader = new FileReader();
        reader.onload = function (e) {
            $("#previewImage").attr("src", e.target.result);
        }
        //Imagepath.files[0] is blob type
        reader.readAsDataURL(e.files[0]);
    }
    </script>
</head>
<body >
    <div>
    <input type="file" name="fileupload" value="fileupload" id="fileupload" onchange='showpreview(this)'>
    </div>
    <div>
        &nbsp;
    </div>
    <div>
    <img width="50%" id="previewImage">
    </div>
</body>
</html>

I had a similar problem; the anchor text in my Bootstrap4 navbar wasn't centered. Simply added text-center in the anchor's class.

Not all python modules are written in python. Datetime happens to be one of them that is not, and (on linux) is datetime.so.

You would have to download the source code to the python standard library to get at it.

You need to go there

/jdk1.8.0_152 | /jre | /lib | /security | java.security and uncomment the

#crypto.policy=unlimited

to

crypto.policy=unlimited

The only option I have found to do this is find some exact wording and put that under the "Has the words" option. Its not the best option, but it works.

In my case, even my system is not behind proxy, I got same issue. I was able to resolve by typing mvn help:archetype before mvn archetype:generate

I am not sure if this will still help someone, but I've done all of the solutions above (and from some other posts) to no avail.

What fixed the issue on my end was to put a backslash to the end of RedirectUri value in the web.config (crazy, I know!). RedirectUri is a parameter in UseOpenIdConnectAuthentication.

So, instead of:

<add key="ida:RedirectUri" value="https://www.bogussite.com/home" />

Do this:

<add key="ida:RedirectUri" value="https://www.bogussite.com/home/" />

And updated the Reply URL on the Azure App Settings as well.

That somehow made the Startup to run as expected (probably cleared some cache), and the breakpoints are now firing.

FYI. I was modelling my code from here: https://github.com/microsoftgraph/aspnet-connect-sample

if you just want a human readable time string and not that exact format:

$t = localtime;
print "$t\n";

prints

Mon Apr 27 10:16:19 2015

or whatever is configured for your locale.

in IE you can get the event object by window.event in other browsers with no 'use strict' directive, it is possible to get by arguments.callee.caller.arguments[0].

function myFunc(p1, p2, p3) {
    var evt = window.event || arguments.callee.caller.arguments[0];
}

yourPictureBox.ImageLocation = "http://www.gravatar.com/avatar/6810d91caff032b202c50701dd3af745?d=identicon&r=PG"

I think this message is not about avoiding to use switch. Instead it wants you to check for hasOwnProperty. The background can be read here: https://stackoverflow.com/a/16735184/1374488

After a few years and many attempts (I tried all the answers given here, but all of them had minor drawbacks at the end), now I realize that there is a better way than wanting to start, stop, restart a daemon directly from Python: use the OS tools instead.

For example, for Linux, instead of doing python myapp start and python myapp stop, I do this to start the app:

screen -S myapp python myapp.py    
CTRL+A, D to detach

or screen -dmS myapp python myapp.py to start and detach it in one command.

Then:

screen -r myapp

to attach to this terminal again. Once in the terminal, it's possible to use CTRL+C to stop it.

Most of the time when this happens it is bad data in the SQL column. This is the proper way to insert into an image column:

INSERT INTO [TableX] (ImgColumn) VALUES (
(SELECT * FROM OPENROWSET(BULK N'C:\....\Picture 010.png', SINGLE_BLOB) as tempimg))

Most people do it incorrectly this way:

INSERT INTO [TableX] (ImgColumn) VALUES ('C:\....\Picture 010.png'))

There is nothing available that I'm aware of. The next best thing would be to simply have one script execute another via CLI, but that's a bit rudimentary. Depending on what you are trying to do and how complex it is, this may or may not be an option.

I find it useful to understand the underlying tools. These are cl.exe (compiler) and link.exe (linker). You need to tell the compiler the signatures of the functions you want to call in the dynamic library (by including the library's header) and you need to tell the linker what the library is called and how to call it (by including the "implib" or import library).

This is roughly the same process gcc uses for linking to dynamic libraries on *nix, only the library object file differs.

Knowing the underlying tools means you can more quickly find the appropriate settings in the IDE and allows you to check that the commandlines generated are correct.

Example

Say A.exe depends B.dll. You need to include B's header in A.cpp (#include "B.h") then compile and link with B.lib:

cl A.cpp /c /EHsc
link A.obj B.lib

The first line generates A.obj, the second generates A.exe. The /c flag tells cl not to link and /EHsc specifies what kind of C++ exception handling the binary should use (there's no default, so you have to specify something).

If you don't specify /c cl will call link for you. You can use the /link flag to specify additional arguments to link and do it all at once if you like:

cl A.cpp /EHsc /link B.lib

If B.lib is not on the INCLUDE path you can give a relative or absolute path to it or add its parent directory to your include path with the /I flag.

If you're calling from cygwin (as I do) replace the forward slashes with dashes.

If you write #pragma comment(lib, "B.lib") in A.cpp you're just telling the compiler to leave a comment in A.obj telling the linker to link to B.lib. It's equivalent to specifying B.lib on the link commandline.

You have to set setOnItemLongClickListener() in the ListView:

lv.setOnItemLongClickListener(new OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                    int pos, long id) {
                // TODO Auto-generated method stub

                Log.v("long clicked","pos: " + pos);

                return true;
            }
        }); 

The XML for each item in the list (should you use a custom XML) must have android:longClickable="true" as well (or you can use the convenience method lv.setLongClickable(true);). This way you can have a list with only some items responding to longclick.

Hope this will help you.

In my case it was a permission issue. I had to:

• chmod a+wrx the image,

then it worked.

If you are using .net core, then during development you can bypass certificate validation by using compiler directives. This way will only validate certificate for release and not for debug:

#if (DEBUG)
        client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication =
                new X509ServiceCertificateAuthentication()
                {
                    CertificateValidationMode = X509CertificateValidationMode.None,
                    RevocationMode = System.Security.Cryptography.X509Certificates.X509RevocationMode.NoCheck
                };   #endif

var values = new int[] {5,7,3};
var sortedValues = values.OrderBy(v => v).ToList();   // result 3,5,7

Just the code below was enough for me!

const baseUrl = `${request.protocol}://${request.headers.host}`;
// http://127.0.0.1:3333

os.path works in a funny way. It looks like os should be a package with a submodule path, but in reality os is a normal module that does magic with sys.modules to inject os.path. Here's what happens:

• When Python starts up, it loads a bunch of modules into sys.modules. They aren't bound to any names in your script, but you can access the already-created modules when you import them in some way.

  • sys.modules is a dict in which modules are cached. When you import a module, if it already has been imported somewhere, it gets the instance stored in sys.modules.

• os is among the modules that are loaded when Python starts up. It assigns its path attribute to an os-specific path module.

• It injects sys.modules['os.path'] = path so that you're able to do "import os.path" as though it was a submodule.

I tend to think of os.path as a module I want to use rather than a thing in the os module, so even though it's not really a submodule of a package called os, I import it sort of like it is one and I always do import os.path. This is consistent with how os.path is documented.

Incidentally, this sort of structure leads to a lot of Python programmers' early confusion about modules and packages and code organization, I think. This is really for two reasons

1. If you think of os as a package and know that you can do import os and have access to the submodule os.path, you may be surprised later when you can't do import twisted and automatically access twisted.spread without importing it.

2. It is confusing that os.name is a normal thing, a string, and os.path is a module. I always structure my packages with empty __init__.py files so that at the same level I always have one type of thing: a module/package or other stuff. Several big Python projects take this approach, which tends to make more structured code.

In the START menu type "regedit" to open the Registry editor

Go to "HKEY_LOCAL_MACHINE" on the left-hand side registry explorer/tree menu

Click "SOFTWARE" within the "HKEY_LOCAL_MACHINE" registries

Click "JavaSoft" within the "SOFTWARE" registries

Click "Java Runtime Environment" within the "JavaSoft" list of registries here you can see different versions of installed java

Click "Java Runtime Environment"- On right hand side you will get 4-5 rows . Please select "CurrentVersion" and right Click( select modify option) Change version to "1.7"

Now the magic has been completed

The simple way to do this is by using the round buit-in.

round(2.6463636263,2) would be displayed as 2.65.

It seems there is an issue with glibc that affects the memory allocation in Pandas: https://github.com/pandas-dev/pandas/issues/2659

The monkey patch detailed on this issue has resolved the problem for me:

# monkeypatches.py

# Solving memory leak problem in pandas
# https://github.com/pandas-dev/pandas/issues/2659#issuecomment-12021083
import pandas as pd
from ctypes import cdll, CDLL
try:
    cdll.LoadLibrary("libc.so.6")
    libc = CDLL("libc.so.6")
    libc.malloc_trim(0)
except (OSError, AttributeError):
    libc = None

__old_del = getattr(pd.DataFrame, '__del__', None)

def __new_del(self):
    if __old_del:
        __old_del(self)
    libc.malloc_trim(0)

if libc:
    print('Applying monkeypatch for pd.DataFrame.__del__', file=sys.stderr)
    pd.DataFrame.__del__ = __new_del
else:
    print('Skipping monkeypatch for pd.DataFrame.__del__: libc or malloc_trim() not found', file=sys.stderr)

Just to add to this. You will get this error too, when you are running ng serve not from within your project folder. So always make sure your bash runs from your project folder.

IE6 Internet Explorer 6

Percent only works for the width of an element, but height:100%; does not work without the correct code.

CSS

html, body { height:100%; } 

Then using a percentage works properly, and dynamically updates on window resize.

<img src="image.jpg" style="height:80%;">

You do not need a width attribute, the width scales proportionately as the browser window size is changed.

And this little gem, is in case the image is scaled up, it will not look (overly) blocky (it interpolates).

img { -ms-interpolation-mode: bicubic; }

This search for a file link explains how to find a file. I did have to muck around with the advice to make it work.

1. cd "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE"
2. tf dir "$/*.sql" /recursive /server:http://mytfsserver:8080/tfs

In the case of the cd command, I performed the cd command because I was looking for the tf.exe file. It was easier to just start from that directory verses adding the whole path. Now that I understand how to make this work, I'd use the absolute path in quotes.

In case of the tf search, I started at the root of the server with $/ and I searched for all files that ended with sql i.e. *.sql. If you don't want to start at the root, then use "$/myproject/*.sql" instead.

Oh! This does not solve the search in file part of the question but my Google search brought me here to find files among other links.

In case you're dealing with <a> tag, and you want to interrupt going to the default href you should use this instead.

Go to default url (yahoo):

<a href="https://yahoo.com" onclick="location.href='https://google.com';"> 

Go to new url (google) onclick:

<a href="https://yahoo.com" onclick="this.href='https://google.com';">

By using this you're interrupting the current browser onclick event and changing href before continuing to default behaviour of <a href='...

SSMS only allows unlimited data for XML data. This is not the default and needs to be set in the options.

One trick which might work in quite limited circumstances is simply naming the column in a special manner as below so it gets treated as XML data.

DECLARE @S varchar(max) = 'A'

SET @S =  REPLICATE(@S,100000) + 'B' 

SELECT @S as [XML_F52E2B61-18A1-11d1-B105-00805F49916B]

In SSMS (at least versions 2012 to current of 18.3) this displays the results as below

Clicking on it opens the full results in the XML viewer. Scrolling to the right shows the last character of B is preserved,

However this does have some significant problems. Adding extra columns to the query breaks the effect and extra rows all become concatenated with the first one. Finally if the string contains characters such as < opening the XML viewer fails with a parsing error.

A more robust way of doing this that avoids issues of SQL Server converting < to < etc or failing due to these characters is below (credit Adam Machanic here).

DECLARE @S varchar(max)

SELECT @S = ''

SELECT @S = @S + '
' + OBJECT_DEFINITION(OBJECT_ID) FROM SYS.PROCEDURES

SELECT @S AS [processing-instruction(x)] FOR XML PATH('')

As Per Java 8, we can use this way.

double[][] arr = new double[20][4]; Arrays.stream(arr).forEach(a -> Arrays.fill(a, 0));

We can initialize a value in multidimensional array in a nicer and smart way.

Of course there IS a way to create files without opening. It's as easy as calling os.mknod("newfile.txt"). The only drawback is that this call requires root privileges on OSX.

Checkout intent properties like no history , clear back stack etc ... Intent.setFlags

Intent mStartActivity = new Intent(HomeActivity.this, SplashScreen.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(HomeActivity.this, mPendingIntentId, mStartActivity,
PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager) HomeActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);

I did the test using java 8 It wont matter the order the builder always takes 0 milliseconds and the concat between 26 and 33 milliseconds under and iteration of a 1000 concatenation

Hope it helps try it with your ide

public void count() {

        String result = "";

        StringBuilder builder = new StringBuilder();

        long millis1 = System.currentTimeMillis(),
            millis2;

        for (int i = 0; i < 1000; i++) {
            builder.append("hello world this is the concat vs builder test enjoy");
        }

        millis2 = System.currentTimeMillis();

        System.out.println("Diff: " + (millis2 - millis1));

        millis1 = System.currentTimeMillis();

        for (int i = 0; i < 1000; i++) {
            result += "hello world this is the concat vs builder test enjoy";
        }

        millis2 = System.currentTimeMillis();

        System.out.println("Diff: " + (millis2 - millis1));
    }

You can use the Like operator with a wildcard to determine whether a given substring exists in a string, for example:

If cell.Value Like "*Word1*" Then
'...
ElseIf cell.Value Like "*Word2*" Then
'...
End If

In this example the * character in "*Word1*" is a wildcard character which matches zero or more characters.

NOTE: The Like operator is case-sensitive, so "Word1" Like "word1" is false, more information can be found on this MSDN page.

        if ( !isset($data) or empty($data) ) return '';

            '/%0[0-8bcef]/',            // url encoded 00-08, 11, 12, 14, 15
            '/%1[0-9a-f]/',             // url encoded 16-31
            '/[\x00-\x08]/',            // 00-08
            '/\x0b/',                   // 11
            '/\x0c/',                   // 12
            '/[\x0e-\x1f]/'             // 14-31
        );
        foreach ( $non_displayables as $regex )
            $data = preg_replace( $regex, '', $data );
        $data = str_replace("'", "''", $data );
        return $data;

with this serial number you can then identify your laptop model if you need ,from the makers service website-usually..:):)

I had to do exactly that.:):)

pathlib module, introduced in Python 3.4 (PEP 428 — The pathlib module — object-oriented filesystem paths), makes path-related experience much much better.

$ pwd
/home/skovorodkin/stack
$ tree
.
+-- scripts
    +-- 1.py
    +-- 2.py

In order to get current working directory use Path.cwd():

from pathlib import Path

print(Path.cwd())  # /home/skovorodkin/stack

To get an absolute path to your script file, use Path.resolve() method:

print(Path(__file__).resolve())  # /home/skovorodkin/stack/scripts/1.py

And to get path of a directory where your script is located, access .parent (it is recommended to call .resolve() before .parent):

print(Path(__file__).resolve().parent)  # /home/skovorodkin/stack/scripts

Remember that __file__ is not reliable in some situations: How do I get the path of the current executed file in Python?.

Please note, that Path.cwd(), Path.resolve() and other Path methods return path objects (PosixPath in my case), not strings. In Python 3.4 and 3.5 that caused some pain, because open built-in function could only work with string or bytes objects, and did not support Path objects, so you had to convert Path objects to strings or use Path.open() method, but the latter option required you to change old code:

$ cat scripts/2.py
from pathlib import Path

p = Path(__file__).resolve()

with p.open() as f: pass
with open(str(p)) as f: pass
with open(p) as f: pass

print('OK')

$ python3.5 scripts/2.py
Traceback (most recent call last):
  File "scripts/2.py", line 11, in <module>
    with open(p) as f:
TypeError: invalid file: PosixPath('/home/skovorodkin/stack/scripts/2.py')

As you can see open(p) does not work with Python 3.5.

PEP 519 — Adding a file system path protocol, implemented in Python 3.6, adds support of PathLike objects to open function, so now you can pass Path objects to open function directly:

$ python3.6 scripts/2.py
OK

$('body').on("click mousedown mouseup focus blur keydown change mouseup click dblclick mousemove mouseover mouseout mousewheel keydown keyup keypress textInput touchstart touchmove touchend touchcancel resize scroll zoom focus blur select change submit reset",function(e){
     console.log(e);
}); 

There is a simple method for deleting selected items, and all these people are going for a hard method:

lstYOURVARIABLE.Items.Remove(lstYOURVARIABLE.SelectedItem)

I used this in Visual Basic mode on Visual Studio.

You'll probably want to get several random numbers, and may want to be able to specify a different range for each one, so you should define a function. In my example, I generate numbers from 25 through 30 with call:rand 25 30. And the result is in RAND_NUM after that function exits.

@echo off & setlocal EnableDelayedExpansion

for /L %%a in (1 1 10) do (
        call:rand 25 30
        echo !RAND_NUM!
)

goto:EOF

REM The script ends at the above goto:EOF.  The following are functions.

REM rand()
REM Input: %1 is min, %2 is max.
REM Output: RAND_NUM is set to a random number from min through max.
:rand
SET /A RAND_NUM=%RANDOM% * (%2 - %1 + 1) / 32768 + %1
goto:EOF

I managed to do it myself. No need for any plugins. Check out my gist:

// Replace #fromA with your button/control and #toB with the target to which     
// You wanna scroll to. 
//
$("#fromA").click(function() {
    $("html, body").animate({ scrollTop: $("#toB").offset().top }, 1500);
});

According to https://bugzilla.mozilla.org/show_bug.cgi?id=592284, the pref network.http.connection-retry-timeout controls the amount of time in ms (Milliseconds !) to wait for success on the initial connection before beginning the second one. Setting it to 0 disables the parallel connection.

You can convert your RDD to a DataFrame then show() it.

// For implicit conversion from RDD to DataFrame
import spark.implicits._

fruits = sc.parallelize([("apple", 1), ("banana", 2), ("orange", 17)])

// convert to DF then show it
fruits.toDF().show()

This will show the top 20 lines of your data, so the size of your data should not be an issue.

+------+---+                                                                    
|    _1| _2|
+------+---+
| apple|  1|
|banana|  2|
|orange| 17|

Its best practice to have TOP 1 1 always.

What if I use SELECT 1 -> If condition matches more than one record then your query will fetch all the columns records and returns 1.

What if I use SELECT TOP 1 1 -> If condition matches more than one record also, it will just fetch the existence of any row (with a self 1-valued column) and returns 1.

IF EXISTS (SELECT TOP 1 1 FROM tblGLUserAccess WHERE GLUserName ='xxxxxxxx') 
BEGIN
   SELECT 1 
END
ELSE
BEGIN
    SELECT 2
END

it is simple but the first time it takes time a few steps to set !!!

1. you have the latest version on node.

2. go to the environment variable and set the path "%SystemRoot%\system32".

3. run cmd as administrator mode.

4. write command npm start.

Better solution is to introduce another interface for async operations. New interface must inherit from original interface.

Example:

interface IIO
{
    void DoOperation();
}

interface IIOAsync : IIO
{
    Task DoOperationAsync();
}


class ClsAsync : IIOAsync
{
    public void DoOperation()
    {
        DoOperationAsync().GetAwaiter().GetResult();
    }

    public async Task DoOperationAsync()
    {
        //just an async code demo
        await Task.Delay(1000);
    }
}


class Program
{
    static void Main(string[] args)
    {
        IIOAsync asAsync = new ClsAsync();
        IIO asSync = asAsync;

        Console.WriteLine(DateTime.Now.Second);

        asAsync.DoOperation();
        Console.WriteLine("After call to sync func using Async iface: {0}", 
            DateTime.Now.Second);

        asAsync.DoOperationAsync().GetAwaiter().GetResult();
        Console.WriteLine("After call to async func using Async iface: {0}", 
            DateTime.Now.Second);

        asSync.DoOperation();
        Console.WriteLine("After call to sync func using Sync iface: {0}", 
            DateTime.Now.Second);

        Console.ReadKey(true);
    }
}

P.S. Redesign your async operations so they return Task instead of void, unless you really must return void.

Try this way:

select * from tab
where DateCol between DateAdd(DD,-7,GETDATE() ) and GETDATE() 

You don't need to go level up and use .. since all buttons are on the same level:

//button[contains(.,'Arcade Reader')]/preceding-sibling::button[@name='settings']

If you have a List of type string that you want in a drop down list I do the following:

EDIT: Clarified, making it a fuller example.

public class ShipDirectory
{
    public string ShipDirectoryName { get; set; }
    public List<string> ShipNames { get; set; }
}

ShipDirectory myShipDirectory = new ShipDirectory()
{
    ShipDirectoryName = "Incomming Vessels",
    ShipNames = new List<string>(){"A", "A B"},
}

myShipDirectory.ShipNames.Add("Aunt Bessy");

@Html.DropDownListFor(x => x.ShipNames, new SelectList(Model.ShipNames), "Select a Ship...", new { @style = "width:500px" })

Which gives a drop down list like so:

<select id="ShipNames" name="ShipNames" style="width:500px">
    <option value="">Select a Ship...</option>
    <option>A</option>
    <option>A B</option>
    <option>Aunt Bessy</option>
</select>

To get the value on a controllers post; if you are using a model (e.g. MyViewModel) that has the List of strings as a property, because you have specified x => x.ShipNames you simply have the method signature as (because it will be serialised/deserialsed within the model):

public ActionResult MyActionName(MyViewModel model)

Access the ShipNames value like so: model.ShipNames

If you just want to access the drop down list on post then the signature becomes:

public ActionResult MyActionName(string ShipNames)

EDIT: In accordance with comments have clarified how to access the ShipNames property in the model collection parameter.

You can use the back button callback, like this:

- (BOOL) navigationShouldPopOnBackButton
{
    [self backAction];
    return NO;
}

- (void) backAction {
    // your code goes here
    // show confirmation alert, for example
    // ...
}

for swift version you can do something like in global scope

extension UIViewController {
     @objc func navigationShouldPopOnBackButton() -> Bool {
     return true
    }
}

extension UINavigationController: UINavigationBarDelegate {
     public func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {
          return self.topViewController?.navigationShouldPopOnBackButton() ?? true
    }
}

Below one you put in the viewcontroller where you want to control back button action:

override func navigationShouldPopOnBackButton() -> Bool {
    self.backAction()//Your action you want to perform.

    return true
}

I'd do (added caching):

var bbx = $("#blackbox");
 bbx.css('background-color') === 'rgb(255, 192, 203)' ? bbx.css('background','black') : bbx.css('background','pink')

wroking fiddle (new AGAIN): http://jsfiddle.net/6nar4/37/

I had to change the first operator as css() returns the rgb value of the color

System.Diagnostics.Debug.WriteLine() will work, but you have to be looking in the right place for the output. In Visual Studio 2010, on the menu bar, click Debug -> Windows -> Output. Now, at the bottom of the screen docked next to your error list, there should be an output tab. Click it and double check it's showing output from the debug stream on the dropdown list.

P.S.: I think the output window shows on a fresh install, but I can't remember. If it doesn't, or if you closed it by accident, follow these instructions.

ADT Plugin (UNSUPPORTED)

The Eclipse ADT plugin is no longer supported, as per this announcement in June 2015.

The Eclipse ADT plugin has many known bugs and potential security bugs that will not be fixed.

You should immediately switch to use Android Studio, the official IDE for Android.

For help transitioning your projects, read Migrate to Android Studio.

I was able to get this working with CSS only.

The trick is to use display: flex; and flex-direction: column-reverse;

The browser treats the bottom like its the top. Assuming the browsers you're targeting support flex-box, the only caveat is that the markup has to be in reverse order.

Here is a working example. https://codepen.io/jimbol/pen/YVJzBg

If you want to kill the Sticky Service,the following command NOT WORKING:

adb shell am force-stop <PACKAGE>
adb shell kill <PID>

The following command is WORKING:

adb shell pm disable <PACKAGE>

If you want to restart the app,you must run command below first:

adb shell pm enable <PACKAGE>

You can use Newtonsoft.Json, it's a dependency of Microsoft.AspNet.Mvc.ModelBinding which is a dependency of Microsoft.AspNet.Mvc. So, you don't need to add a dependency in your project.json.

#using Newtonsoft.Json
....
JsonConvert.DeserializeObject(json);

Note, using a WebAPI controller you don't need to deal with JSON.

UPDATE ASP.Net Core 3.0

Json.NET has been removed from the ASP.NET Core 3.0 shared framework.

You can use the new JSON serializer layers on top of the high-performance Utf8JsonReader and Utf8JsonWriter. It deserializes objects from JSON and serializes objects to JSON. Memory allocations are kept minimal and includes support for reading and writing JSON with Stream asynchronously.

To get started, use the JsonSerializer class in the System.Text.Json.Serialization namespace. See the documentation for information and samples.

To use Json.NET in an ASP.NET Core 3.0 project:

• Add a package reference to Microsoft.AspNetCore.Mvc.NewtonsoftJson
• Update ConfigureServices to call AddNewtonsoftJson().

    services.AddMvc()
        .AddNewtonsoftJson();

Read Json.NET support in Migrate from ASP.NET Core 2.2 to 3.0 Preview 2 for more information.

On mac OS X Yosemite, after installing it with brew it put it into

/usr/local/opt/openssl/bin/openssl

But kept getting an error "Linking keg-only openssl means you may end up linking against the insecure" when trying to link it

So I just linked it by supplying the full path like so

ln -s /usr/local/opt/openssl/bin/openssl /usr/local/bin/openssl

Now it's showing version OpenSSL 1.0.2o when I do "openssl version -a", I'm assuming it worked

After setting the gems directory to the user directory that runs the gem install, using export GEM_HOME=/home/<user>/gems, the issue has been solved.

All such complex sugestions while the solution is so short and easy:

#!/bin/bash

BRANCH="<your branch name>"
LAST_UPDATE=`git show --no-notes --format=format:"%H" $BRANCH | head -n 1`
LAST_COMMIT=`git show --no-notes --format=format:"%H" origin/$BRANCH | head -n 1`

git remote update
if [ $LAST_COMMIT != $LAST_UPDATE ]; then
        echo "Updating your branch $BRANCH"
        git pull --no-edit
else
        echo "No updates available"
fi

In case you want to get parts of an URL that you have stored in a variable, I can recommend URL-Parse

const Url = require('url-parse');
const url = new Url('https://github.com/foo/bar');

According to the documentation, it extracts the following parts:

The returned url instance contains the following properties:

protocol: The protocol scheme of the URL (e.g. http:). slashes: A boolean which indicates whether the protocol is followed by two forward slashes (//). auth: Authentication information portion (e.g. username:password). username: Username of basic authentication. password: Password of basic authentication. host: Host name with port number. hostname: Host name without port number. port: Optional port number. pathname: URL path. query: Parsed object containing query string, unless parsing is set to false. hash: The "fragment" portion of the URL including the pound-sign (#). href: The full URL. origin: The origin of the URL.

Best way to deal with this issue using ngIf Because this well prevent getting that element render in front-end,

If you use [hidden]="true" or style hide [style.display] it will only hide element in front end and someone can change the value and visible it easily, In my opinion best way to hide element is ngIf

<div *ngIf="myVar">stuff</div>

and also If you have multiple element (need to implement else also) you can Use <ng-template> option

<ng-container *ngIf="myVar; then loadAdmin else loadMenu"></ng-container>
<ng-template #loadMenu>
     <div>loadMenu</div>
</ng-template>

<ng-template #loadAdmin>
     <div>loadAdmin</div>
</ng-template>  

sample ng-template code

For me the thing that worked was the order in which the namespaces were defined in the xsi:schemaLocation tag : [ since the version was all good and also it was transaction-manager already ]

The error was with :

Make sure the file you're using ('C:\Users\Michael\workspace\pydb\data\andrew.out.txt') is on the SQL server machine and not the client machine running MSSMS.

I think you've created your project like this:

vue init webpack myproject

Well, now you can run

npm run build

Copy index.html and /dist/ folder into your website root directory. Done.

I think you are trying to run some utility or shell script from UNIX\LINUX which has some GUI. Anyways

SOLUTION: dude all you need is an XServer & X11 forwarding enabled. I use XMing (XServer). You are already enabling X11 forwarding. Just Install it(XMing) and keep it running when you create the session with PuTTY.

A boolean is not an integer; 1 and 0 are not boolean values in Java. You'll need to convert them explicitly:

boolean multipleContacts = (1 == jsonObject.getInt("MultipleContacts"));

or serialize the ints as booleans from the start.

SELECT count(*)         -- or count(myCol)
FROM   <table name>     -- replace <table name> with your table
WHERE  myCol = true;

Here's a way with Windowing Function:

SELECT DISTINCT *, count(*) over(partition by myCol)
FROM   <table name>;

-- Outputs:
-- --------------
-- myCol | count
-- ------+-------
--  f    |  2
--  t    |  3
--       |  1

Reimeus is right, you see this because of in.close in your chooseCave(). Also, this is wrong.

if (playAgain == "yes") {
      play = true;
}

You should use equals instead of "==".

if (playAgain.equals("yes")) {
      play = true;
}

_bitmapScaled.compress() should do the trick. Check out the docs: http://developer.android.com/reference/android/graphics/Bitmap.html#compress(android.graphics.Bitmap.CompressFormat, int, java.io.OutputStream)

A list of the few remaining cosmetic and packaging differences between Oracle JDK 11 and OpenJDK 11 can be found in this blog post:

https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later

In short:

• Oracle JDK 11 emits a warning when using the -XX:+UnlockCommercialFeatures option,
• it can be configured to provide usage log data to the “Advanced Management Console” tool,
• it has always required third party cryptographic providers to be signed by a known certificate,
• it will continue to include installers, branding and JRE packaging,
• while the javac --release command behaves slightly differently for the Java 9 and Java 10 targets, and
• the output of the java --version and java -fullversion commands will distinguish Oracle JDK builds from OpenJDK builds.

(cd dir && ls)

will only output filenames in dir. Use ls -1 if you want one per line.

(Changed ; to && as per Sactiw's comment).

The answer you're looking for as of June, 2013 can be found here:

https://gist.github.com/dineshcooper/2111366

It's accomplished using jQuery to rewrite the inner HTML of the parent container that holds the facebook widget.

Hope this helps!

This is exactly what I needed for my MVC site configuration!

I added a little modification to the OnException method to handle multiple HandleErrorAttribute instances, as suggested by Atif Aziz:

bear in mind that you may have to take care that if multiple HandleErrorAttribute instances are in effect then duplicate logging does not occur.

I simply check context.ExceptionHandled before invoking the base class, just to know if someone else handled the exception before current handler.
It works for me and I post the code in case someone else needs it and to ask if anyone knows if I overlooked anything.

Hope it is useful:

public override void OnException(ExceptionContext context)
{
    bool exceptionHandledByPreviousHandler = context.ExceptionHandled;

    base.OnException(context);

    Exception e = context.Exception;
    if (exceptionHandledByPreviousHandler
        || !context.ExceptionHandled  // if unhandled, will be logged anyhow
        || RaiseErrorSignal(e)        // prefer signaling, if possible
        || IsFiltered(context))       // filtered?
        return;

    LogException(e);
}

For a production system, you can use this configuration :

--ACCESS DB
REVOKE CONNECT ON DATABASE nova FROM PUBLIC;
GRANT  CONNECT ON DATABASE nova  TO user;

--ACCESS SCHEMA
REVOKE ALL     ON SCHEMA public FROM PUBLIC;
GRANT  USAGE   ON SCHEMA public  TO user;

--ACCESS TABLES
REVOKE ALL ON ALL TABLES IN SCHEMA public FROM PUBLIC ;
GRANT SELECT                         ON ALL TABLES IN SCHEMA public TO read_only ;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO read_write ;
GRANT ALL                            ON ALL TABLES IN SCHEMA public TO admin ;

The fix is that yes, vertical padding and margin are relative to width, but top and bottom aren't.

So just place a div inside another, and in the inner div, use something like top:50% (remember position matters if it still doesn't work)

I just wanted to add to Alper's answer what I had to do to get this stuff working:

On Mac, you'll need brew install coreutils, so we can use gdate. Otherwise on Linux, it's just date. And this function will help you time commands without having to create temporary files or anything:

function timeit() {
    start=`gdate +%s%N`
    bash -c $1
    end=`gdate +%s%N`
    runtime=$(((end-start)/1000000000.0))
    echo " seconds"
}

And you can use it with a string:

timeit 'tsc --noEmit'

The end to all URL query string editing woes

After lots of toil and fiddling with the Uri class, and other solutions, here're my string extension methods to solve my problems.

using System;
using System.Collections.Specialized;
using System.Linq;
using System.Web;

public static class StringExtensions
{
    public static string AddToQueryString(this string url, params object[] keysAndValues)
    {
        return UpdateQueryString(url, q =>
        {
            for (var i = 0; i < keysAndValues.Length; i += 2)
            {
                q.Set(keysAndValues[i].ToString(), keysAndValues[i + 1].ToString());
            }
        });
    }

    public static string RemoveFromQueryString(this string url, params string[] keys)
    {
        return UpdateQueryString(url, q =>
        {
            foreach (var key in keys)
            {
                q.Remove(key);
            }
        });
    }

    public static string UpdateQueryString(string url, Action<NameValueCollection> func)
    {
        var urlWithoutQueryString = url.Contains('?') ? url.Substring(0, url.IndexOf('?')) : url;
        var queryString = url.Contains('?') ? url.Substring(url.IndexOf('?')) : null;
        var query = HttpUtility.ParseQueryString(queryString ?? string.Empty);

        func(query);

        return urlWithoutQueryString + (query.Count > 0 ? "?" : string.Empty) + query;
    }
}

All the answers work but they always traverse the whole list. If I understand your question, you only need the first match. So you don't have to consider the rest of the list if you found your first match:

mylist = ['abc123', 'def456', 'ghi789']
sub = 'abc'
next((s for s in mylist if sub in s), None) # returns 'abc123'

If the match is at the end of the list or for very small lists, it doesn't make a difference, but consider this example:

import timeit

mylist = ['abc123'] + ['xyz123']*1000
sub = 'abc'

timeit.timeit('[s for s in mylist if sub in s]', setup='from __main__ import mylist, sub', number=100000)
# for me 7.949463844299316 with Python 2.7, 8.568840944994008 with Python 3.4
timeit.timeit('next((s for s in mylist if sub in s), None)', setup='from __main__ import mylist, sub', number=100000) 
# for me 0.12696599960327148 with Python 2.7, 0.09955992100003641 with Python 3.4

This will find the index of the N'th smallest or largest value in the input numeric vector x. Set bottom=TRUE in the arguments if you want the N'th from the bottom, or bottom=FALSE if you want the N'th from the top. N=1 and bottom=TRUE is equivalent to which.min, N=1 and bottom=FALSE is equivalent to which.max.

FindIndicesBottomTopN <- function(x=c(4,-2,5,-77,99),N=1,bottom=FALSE)
{

  k1 <- rank(x)
  if(bottom==TRUE){
    Nindex <- which(k1==N)
    Nindex <- Nindex[1]
  }

  if(bottom==FALSE){
    Nindex <- which(k1==(length(x)+1-N))
    Nindex <- Nindex[1]
  }

  return(Nindex)
}

On Visual Studio 2015 just go to: help/about Microsoft Visual Studio Then you will see something like this:

Microsoft Visual Studio Enterprise 2015 Version 14.0.24720.00 Update 1 Microsoft .NET Framework Version 4.6.01055

...

TypeScript 1.7.6.0 TypeScript for Microsoft Visual Studio

....

Your class doesn't have a __init__(), so by the time it's instantiated, the attribute atoms is not present. You'd have to do C.setdata('something') so C.atoms becomes available.

>>> C = Residues()
>>> C.atoms.append('thing')

Traceback (most recent call last):
  File "<pyshell#84>", line 1, in <module>
    B.atoms.append('thing')
AttributeError: Residues instance has no attribute 'atoms'

>>> C.setdata('something')
>>> C.atoms.append('thing')   # now it works
>>> 

Unlike in languages like Java, where you know at compile time what attributes/member variables an object will have, in Python you can dynamically add attributes at runtime. This also implies instances of the same class can have different attributes.

To ensure you'll always have (unless you mess with it down the line, then it's your own fault) an atoms list you could add a constructor:

def __init__(self):
    self.atoms = []

Functions can be "passed" as function pointers, as per ISO C11 6.7.6.3p8: "A declaration of a parameter as ‘‘function returning type’’ shall be adjusted to ‘‘pointer to function returning type’’, as in 6.3.2.1. ". For example, this:

void foo(int bar(int, int));

is equivalent to this:

void foo(int (*bar)(int, int));

You can use VLOOKUP, but this requires a wrapper function to return True or False. Not to mention it is (relatively) slow. Use COUNTIF or MATCH instead.

Fill down this formula in column K next to the existing values in column I (from I1 to I2691):

=COUNTIF(<entire column E range>,<single column I value>)>0
=COUNTIF($E$1:$E$99504,$I1)>0

You can also use MATCH:

=NOT(ISNA(MATCH(<single column I value>,<entire column E range>)))
=NOT(ISNA(MATCH($I1,$E$1:$E$99504,0)))

You just need to add 'table-layout: fixed;'

.table {
   display: table;
   height: 100px;
   width: 100%;
   table-layout: fixed;
}

Try with this:

msg.setContent(email.getBody(), "text/html; charset=ISO-8859-1");

Use this if you also want to consider non-javascript users:

echo ("<SCRIPT LANGUAGE='JavaScript'>
           window.alert('Succesfully Updated')
           window.location.href='http://someplace.com';
       </SCRIPT>
       <NOSCRIPT>
           <a href='http://someplace.com'>Successfully Updated. Click here if you are not redirected.</a>
       </NOSCRIPT>");

As everyone else has said... the .equals method is what you need.

In the off chance you used something like:

if(argv[0] == "a")

then it does not work because == compares the location of the two objects (physical equality) rather than the contents (logical equality).

Since "a" from the command line and "a" in the source for your program are allocated in two different places the == cannot be used. You have to use the equals method which will check to see that both strings have the same characters.

Another note... "a" == "a" will work in many cases, because Strings are special in Java, but 99.99999999999999% of the time you want to use .equals.

Here is one of the way in mongodb you can achieve this.

db.usercollection.find({ $where: 'this.name.length < 4' })

Visual Studio Code: Version 1.14.2 (1.14.2)

1. Press Shift + Command + P to open panel
   • For non-macOS users, press Ctrl+P
2. Enter "settings.json" to open setting files.

3. At default setting, you can see this:

   // Columns at which to show vertical rulers
   "editor.rulers": [],
   

   This means the empty array won't show the vertical rulers.

4. At right window "user setting", add the following:

   "editor.rulers": [140]

Save the file, and you will see the rulers.

You can use styles for modifiy the login button like this

<style name="FacebookLoginButton">
    <item name="android:textSize">@dimen/smallTxtSize</item>
    <item name="android:background">@drawable/facebook_signin_btn</item>
    <item name="android:layout_marginTop">10dp</item>
    <item name="android:layout_marginBottom">10dp</item>
    <item name="android:layout_gravity">center_horizontal</item>
</style>

and in layout

<com.facebook.widget.LoginButton
        xmlns:fb="http://schemas.android.com/apk/res-auto"
        android:id="@+id/loginFacebookButton"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        fb:login_text="@string/loginFacebookButton"
        fb:logout_text=""
        style="@style/FacebookLoginButton"/>

Increasing number of max-connections will not solve the problem.

We were experiencing the same situation on our servers. This is what happens

User open a page/view, that connect to the database, query the database, still query(queries) were not finished and user leave the page or move to some other page. So the connection that was open, will remains open, and keep increasing number of connections, if there are more users connecting with the db and doing something similar.

You can set interactive_timeout MySQL, bydefault it is 28800 (8hours) to 1 hour

SET interactive_timeout=3600

From PowerShell Core 6.0 you are able to write & at end of command and it will be equivalent to running you pipeline in background in current working directory.

It's not equivalent to & in bash, it's just a nicer syntax for current PowerShell jobs feature. It returns a job object so you can use all other command that you would use for jobs. For example Receive-Job:

C:\utils> ping google.com &

Id     Name            PSJobTypeName   State         HasMoreData     Location             Command

If you want to execute couple of statements in background you can combine & call operator, { } script block and this new & background operator like here:

& { cd .\SomeDir\; .\SomeLongRunningOperation.bat; cd ..; } &

Here's some more info from documentation pages:

from What's New in PowerShell Core 6.0:

Support backgrounding of pipelines with ampersand (&) (#3360)

Putting & at the end of a pipeline causes the pipeline to be run as a PowerShell job. When a pipeline is backgrounded, a job object is returned. Once the pipeline is running as a job, all of the standard *-Job cmdlets can be used to manage the job. Variables (ignoring process-specific variables) used in the pipeline are automatically copied to the job so Copy-Item $foo $bar & just works. The job is also run in the current directory instead of the user's home directory. For more information about PowerShell jobs, see about_Jobs.

from about_operators / Ampersand background operator &:

Ampersand background operator &

Runs the pipeline before it in a PowerShell job. The ampersand background operator acts similarly to the UNIX "ampersand operator" which famously runs the command before it as a background process. The ampersand background operator is built on top of PowerShell jobs so it shares a lot of functionality with Start-Job. The following command contains basic usage of the ampersand background operator.

Get-Process -Name pwsh &

This is functionally equivalent to the following usage of Start-Job.

Start-Job -ScriptBlock {Get-Process -Name pwsh}

Since it's functionally equivalent to using Start-Job, the ampersand background operator returns a Job object just like Start-Job does. This means that you are able to use Receive-Job and Remove-Job just as you would if you had used Start-Job to start the job.

$job = Get-Process -Name pwsh &
Receive-Job $job

Output

NPM(K)    PM(M)      WS(M)     CPU(s)      Id  SI ProcessName

Prasoon has already offered up a host of different (and good) ways to do this, none of which need repeating here. I'd like to suggest an alternative approach for speed however.

If you're going to be doing this quite a bit, you may want to consider "sub-classing" your vector so that a sum of elements is maintained separately (not actually sub-classing vector which is iffy due to the lack of a virtual destructor - I'm talking more of a class that contains the sum and a vector within it, has-a rather than is-a, and provides the vector-like methods).

For an empty vector, the sum is set to zero. On every insertion to the vector, add the element being inserted to the sum. On every deletion, subtract it. Basically, anything that can change the underlying vector is intercepted to ensure the sum is kept consistent.

That way, you have a very efficient O(1) method for "calculating" the sum at any point in time (just return the sum currently calculated). Insertion and deletion will take slightly longer as you adjust the total and you should take this performance hit into consideration.

Vectors where the sum is needed more often than the vector is changed are the ones likely to benefit from this scheme, since the cost of calculating the sum is amortised over all accesses. Obviously, if you only need the sum every hour and the vector is changing three thousand times a second, it won't be suitable.

Something like this would suffice:

class UberVector:
    private Vector<int> vec
    private int sum

    public UberVector():
        vec = new Vector<int>()
        sum = 0

    public getSum():
        return sum

    public add (int val):
        rc = vec.add (val)
        if rc == OK:
            sum = sum + val
        return rc

    public delindex (int idx):
        val = 0
        if idx >= 0 and idx < vec.size:
            val = vec[idx]
        rc =  vec.delindex (idx)
        if rc == OK:
            sum = sum - val
        return rc

Obviously, that's pseudo-code and you may want to have a little more functionality, but it shows the basic concept.

On a related note: the java compiler uses int to represent boolean since JVM has a limited support for the boolean type.See Section 3.3.4 The boolean type.

In JVM, the integer zero represents false, and any non-zero integer represents true (Source : Inside Java Virtual Machine by Bill Venners)

None of the current answers worked for me because my data was in this format from the unix side:

2016-02-02 19:21:42 UTC

I needed to convert this to Epoch to allow referencing other data which had epoch timestamps.

1. Create a new column for the date part and parse with this formula

   =DATEVALUE(MID(A2,6,2) & "/" & MID(A2,9,2) & "/" & MID(A2,1,4)) 
   

2. As other Grendler has stated here already, create another column

   =(B2-DATE(1970,1,1))*86400 
   

3. Create another column with just the time added together to get total seconds:

   =(VALUE(MID(A2,12,2))*60*60+VALUE(MID(A2,15,2))*60+VALUE(MID(A2,18,2)))
   

4. Create a last column that just adds the last two columns together:

   =C2+D2
   

Using underscore.js or lodash.js, you can do the following on an array of strings:

var contacts = ['Billy Bob', 'John', 'Bill', 'Sarah'];

var filters = ['Bill', 'Sarah'];

contacts = _.filter(contacts, function(contact) {
    return _.every(filters, function(filter) { return (contact.indexOf(filter) === -1); });
});

// ['John']

And on a single string:

var contact = 'Billy';
var filters = ['Bill', 'Sarah'];

_.every(filters, function(filter) { return (contact.indexOf(filter) >= 0); });

// true

What I do is have a static class with the following code in my project:

    #region Dataset -> Immediate Window
public static void printTbl(DataSet myDataset)
{
    printTbl(myDataset.Tables[0]);
}
public static void printTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        Debug.Write(mytable.Columns[i].ToString() + " | ");
    }
    Debug.Write(Environment.NewLine + "=======" + Environment.NewLine);
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            Debug.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        Debug.Write(Environment.NewLine);
    }
}
public static void ResponsePrintTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        HttpContext.Current.Response.Write(mytable.Columns[i].ToString() + " | ");
    }
    HttpContext.Current.Response.Write("<BR>" + "=======" + "<BR>");
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            HttpContext.Current.Response.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        HttpContext.Current.Response.Write("<BR>");
    }
}

public static void printTblRow(DataSet myDataset, int RowNum)
{
    printTblRow(myDataset.Tables[0], RowNum);
}
public static void printTblRow(DataTable mytable, int RowNum)
{
    for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
    {
        Debug.Write(mytable.Columns[ccc].ToString() + " : ");
        Debug.Write(mytable.Rows[RowNum][ccc]);
        Debug.Write(Environment.NewLine);
    }
}
#endregion

I then I will call one of the above functions in the immediate window and the results will appear there as well. For example if I want to see the contents of a variable 'myDataset' I will call printTbl(myDataset). After hitting enter, the results will be printed to the immediate window

phpPgAdmin might work for you, if you're already familiar with phpMyAdmin.

Please note that development of phpPgAdmin has moved to github per this notice but the SourceForge link above is for historical / documentation purposes.

But really there are dozens of tools that can do this.

I'd like to add to OJ's kind clarifications.

Virtual inheritance doesn't come without a price. Like with all things virtual, you get a performance hit. There is a way around this performance hit that is possibly less elegant.

Instead of breaking the diamond by deriving virtually, you can add another layer to the diamond, to get something like this:

   B
  / \
D11 D12
 |   |
D21 D22
 \   /
  DD

None of the classes inherit virtually, all inherit publicly. Classes D21 and D22 will then hide virtual function f() which is ambiguous for DD, perhaps by declaring the function private. They'd each define a wrapper function, f1() and f2() respectively, each calling class-local (private) f(), thus resolving conflicts. Class DD calls f1() if it wants D11::f() and f2() if it wants D12::f(). If you define the wrappers inline you'll probably get about zero overhead.

Of course, if you can change D11 and D12 then you can do the same trick inside these classes, but often that is not the case.

You need to start the script with a preceding dot, this will put the exported variables in the current environment.

#!/bin/bash
...
export output="SUCCESS"

Then execute it like so

chmod +x /tmp/test.sh
. /tmp/test.sh

When you need the entire output and not just a single value, just put the output in a variable like the other answers indicate

In order to create a file in the remote machine with the ad-hoc command

ansible client -m file -a"dest=/tmp/file state=touch"

Please correct me if I am wrong

From the Android documentation:

The recommended way to develop an Android application is to use Eclipse with the ADT plugin... However, if you'd rather develop your application in another IDE, such as IntelliJ, or in a basic editor, such as Emacs, you can do that instead.

Currently, there are plug-ins for IntelliJ IDEA and NetBeans, but you can still use the tools in /tools to build, debug, monitor, measure and start the emulator.

You are trying to get data from an https that does not have certificate. Change "https://" to "http://". Worked for me.

Create a separate ul.nav for just that list item and float that ul right.

I've been using this line to launch the default browser:

System.Diagnostics.Process.Start("http://www.google.com"); 

Based in other opinions, this is what I come up with. This approach avoids having to type .Value where you want to get the constant value.

I have a base class for all string enums like this:

using System;
using Newtonsoft.Json;

[JsonConverter(typeof(ConstantConverter))]
public class StringEnum: IConvertible
{
    public string Value { get; set; }

    protected StringEnum(string value)
    {
        Value = value;
    }

    public static implicit operator string(StringEnum c)
    {
        return c.Value;
    }
    public string ToString(IFormatProvider provider)
    {
        return Value;
    }

    public TypeCode GetTypeCode()
    {
        throw new NotImplementedException();
    }

    public bool ToBoolean(IFormatProvider provider)
    {
        throw new NotImplementedException();
    }
    //The same for all the rest of IConvertible methods
}

The JsonConverter is like this:

using System;
using Newtonsoft.Json;

class ConstantConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return true;
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        if (value == null)
        {
            serializer.Serialize(writer, null);
        }
        else
        {
            serializer.Serialize(writer, value.ToString());
        }
    }
}

And an actual string enum will be something like this:

public sealed class Colors : StringEnum
{
    public static Colors Red { get { return new Catalog("Red"); } }
    public static Colors Yellow { get { return new Catalog("Yellow"); } }
    public static Colors White { get { return new Catalog("White"); } }

    private Colors(string value) : base(value) { }
}

And with this, you can just use Color.Red to even serialize to json without using the Value property

(PartlyStolen from ServerFault)

I think that both are functionally the same, but they simply have different authors, and the one is simply named more appropriately than the other.

Here is a quick backgrounder in naming conventions (for those unfamiliar), which explains the frustration by the question asker: For many *nix applications, the piece that does the backend work is called a "daemon" (think "service" in Windows-land), while the interface or client application is what you use to control or access the daemon. The daemon is most often named the same as the client, with the letter "d" appended to it. For example "imap" would be a client that connects to the "imapd" daemon.

This naming convention is clearly being adhered to by memcache when you read the introduction to the memcache module (notice the distinction between memcache and memcached in this excerpt):

Memcache module provides handy procedural and object oriented interface to memcached, highly effective caching daemon, which was especially designed to decrease database load in dynamic web applications.

The Memcache module also provides a session handler (memcache).

More information about memcached can be found at » http://www.danga.com/memcached/.

The frustration here is caused by the author of the PHP extension which was badly named memcached, since it shares the same name as the actual daemon called memcached. Notice also that in the introduction to memcached (the php module), it makes mention of libmemcached, which is the shared library (or API) that is used by the module to access the memcached daemon:

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

This extension uses libmemcached library to provide API for communicating with memcached servers. It also provides a session handler (memcached).

Information about libmemcached can be found at » http://tangent.org/552/libmemcached.html.

Browser development progresses:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString

 Number.toLocaleString(locale);

 // E.g.
 parseFloat("1234567.891").toLocaleString(window.document.documentElement.lang);
 "1,234,567.891"

If you need just file names like:

dir/subdir/file1.txt
dir/subdir2/file2.sql
dir2/subdir3/file6.php

(which I use as a source for tar command) you will also need to filter out commit messages.

In order to do this I use following command:

git log --name-only --oneline | grep -v '.{7} '

Grep command excludes (-v param) every line which starts with seven symbols (which is the length of my git hash for git log command) followed by space. So it filters out every git hash message line and leave only lines with file names.

One useful improvement is to append uniq to remove duplicate lines so it will looks as follow:

git log --name-only --oneline | grep -v '.{7} ' | uniq

Classloaders can be a tricky problem. You can especially run into problems if you're using multiple classloaders and don't have their interactions clearly and rigorously defined. I think in order to actually be able to unload a class youlre going go have to remove all references to any classes(and their instances) you're trying to unload.

Most people needing to do this type of thing end up using OSGi. OSGi is really powerful and surprisingly lightweight and easy to use,

SARose's answer worked for me until I updated from Ubuntu 20.04 LTS. The slight change I made to his code makes it work on the latest Ubuntu release.

import subprocess

def find_files(file_name):
    command = ['locate'+ ' ' + file_name]
    output = subprocess.Popen(command, stdout=subprocess.PIPE, shell=True).communicate()[0]
    output = output.decode()
    search_results = output.split('\n')
    return search_results

You can adjust pandas print options with set_printoptions.

However this will not work in all cases as pandas detects your console width and it will only use to_string if the output fits in the console (see the docstring of set_printoptions). In this case you can explicitly call to_string as answered by BrenBarn.

There is a simpler way to get the application data directory with min API 4+. From any Context (e.g. Activity, Application):

getApplicationInfo().dataDir

http://developer.android.com/reference/android/content/Context.html#getApplicationInfo()

Depending on your body (or the div which is wrapping your table) 'settings' you should be able to do this:

body {
  width: 98%;
}

table {
  width: 100%;
}


th {
  border: 1px solid black;
}


th.From, th.Date {
  width: 15%;
}

th.Date {
  width: 70%;
}


<table>
  <thead>
    <tr>
      <th class="From">From</th>
      <th class="Subject">Subject</th>
      <th class="Date">Date</th>
    </tr>
   </thead>
   <tbody>
     <tr>
       <td>Me</td>
       <td>Your question</td>
       <td>5/30/2009 2:41:40 AM UTC</td>
     </tr>
   </tbody>
</table>

Demo

In your template you can do like this:

{% jump_link as name %}
{% for obj in name %}
    <div>{{obj.helo}} - {{obj.how}}</div>
{% endfor %}

In your template-tags you can add a tag like this:

@register.assignment_tag
def jump_link():
    listArr = []
    for i in range(5):
        listArr.append({"helo" : i,"how" : i})
    return listArr

Why use getters and setters?

1. Scalability: It's easier refactor a getter than search all the var assignments in a project code.
2. Debugging: You can put breakpoints at setters and getters.
3. Cleaner: Magic functions are not good solution for writting less, your IDE will not suggest the code. Better use templates for fast-writting getters.

Increment lastIndex whenever you look for next occurrence.

Otherwise it's always finding the first substring (at position 0).
