SQL Server does not track licensing. Customers are responsible for tracking the assignment of licenses to servers, following the rules in the Licensing Guide.

I have looked at software protection in general for my own projects and the general philosophy is that complete protection is impossible. The only thing that you can hope to achieve is to add protection to a level that would cost your customer more to bypass than it would to purchase another license.

With that said I was just checking google for python obsfucation and not turning up a lot of anything. In a .Net solution, obsfucation would be a first approach to your problem on a windows platform, but I am not sure if anyone has solutions on Linux that work with Mono.

The next thing would be to write your code in a compiled language, or if you really want to go all the way, then in assembler. A stripped out executable would be a lot harder to decompile than an interpreted language.

It all comes down to tradeoffs. On one end you have ease of software development in python, in which it is also very hard to hide secrets. On the other end you have software written in assembler which is much harder to write, but is much easier to hide secrets.

Your boss has to choose a point somewhere along that continuum that supports his requirements. And then he has to give you the tools and time so you can build what he wants. However my bet is that he will object to real development costs versus potential monetary losses.

If the usage of something is part of the process of you making money, then it's generally considered a commercial use. If the purpose of the site is to, through some means or another, directly or indirectly, make you money, then it's probably commercial use.

If, on the other hand, something is merely incidental (not part of the process of production/working, but instead simply tacked on to the side), there are potential grounds for it not to be considered commercial use.

I had exactly the same problem. Then i installed "Android 7.0 (API 24) > SDK Platform" and it worked.

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

On Windows XP -

1. Reboot into "Safe mode with Command Prompt"
2. Type "explorer" in the command prompt that comes up and push [Enter]
3. Click on Start>Run, and type the following :

   rundll32.exe syssetup,SetupOobeBnk

This will reset the 30 day timer for activation back to 30 days so you can enter in the key normally.

Can I include GPL licensed code in a MIT licensed product?

You can. GPL is free software as well as MIT is, both licenses do not restrict you to bring together the code where as "include" is always two-way.

In copyright for a combined work (that is two or more works form together a work), it does not make much of a difference if the one work is "larger" than the other or not.

So if you include GPL licensed code in a MIT licensed product you will at the same time include a MIT licensed product in GPL licensed code as well.

As a second opinion, the OSI listed the following criteria (in more detail) for both licenses (MIT and GPL):

1. Free Redistribution
2. Source Code
3. Derived Works
4. Integrity of The Author's Source Code
5. No Discrimination Against Persons or Groups
6. No Discrimination Against Fields of Endeavor
7. Distribution of License
8. License Must Not Be Specific to a Product
9. License Must Not Restrict Other Software
10. License Must Be Technology-Neutral

Both allow the creation of combined works, which is what you've been asking for.

If combining the two works is considered being a derivate, then this is not restricted as well by both licenses.

And both licenses do not restrict to distribute the software.

It seems to me that the chief difference between the MIT license and GPL is that the MIT doesn't require modifications be open sourced whereas the GPL does.

The GPL doesn't require you to release your modifications only because you made them. That's not precise.

You might mix this with distribiution of software under GPL which is not what you've asked about directly.

Is that correct - is the GPL is more restrictive than the MIT license?

This is how I understand it:

As far as distribution counts, you need to put the whole package under GPL. MIT code inside of the package will still be available under MIT whereas the GPL applies to the package as a whole if not limited by higher rights.

"Restrictive" or "more restrictive" / "less restrictive" depends a lot on the point of view. For a software-user the MIT might result in software that is more restricted than the one available under GPL even some call the GPL more restrictive nowadays. That user in specific will call the MIT more restrictive. It's just subjective to say so and different people will give you different answers to that.

As it's just subjective to talk about restrictions of different licenses, you should think about what you would like to achieve instead:

• If you want to restrict the use of your modifications, then MIT is able to be more restrictive than the GPL for distribution and that might be what you're looking for.
• In case you want to ensure that the freedom of your software does not get restricted that much by the users you distribute it to, then you might want to release under GPL instead of MIT.

As long as you're the author it's you who can decide.

So the most restrictive person ever is the author, regardless of which license anybody is opting for ;)

Use a seperate column to indicate the join condition

SELECT  t.importid, 
        case 
            when t.importid = g.home 
            then 'home' 
            else 'away' 
        end as join_condition, 
        g.network, 
        g.date_start 
FROM    game g
INNER JOIN team t ON (t.importid = g.home OR t.importid = g.away)
ORDER BY date_start DESC 
LIMIT 7

it's pretty painless to pop a couple methods in a file that will handle asynchronous data in a serialized order and give a more conventional flavour to your code. For example:

module.exports = function () {
  var self = this;

  this.each = async (items, fn) => {
    if (items && items.length) {
      await Promise.all(
        items.map(async (item) => {
          await fn(item);
        }));
    }
  };

  this.reduce = async (items, fn, initialValue) => {
    await self.each(
      items, async (item) => {
        initialValue = await fn(initialValue, item);
      });
    return initialValue;
  };
};

now, assuming that's saved at './myAsync.js' you can do something similar to the below in an adjacent file:

...
/* your server setup here */
...
var MyAsync = require('./myAsync');
var Cat = require('./models/Cat');
var Doje = require('./models/Doje');
var example = async () => {
  var myAsync = new MyAsync();
  var doje = await Doje.findOne({ name: 'Doje', noises: [] }).save();
  var cleanParams = [];

  // FOR EACH EXAMPLE
  await myAsync.each(['bork', 'concern', 'heck'], 
    async (elem) => {
      if (elem !== 'heck') {
        await doje.update({ $push: { 'noises': elem }});
      }
    });

  var cat = await Cat.findOne({ name: 'Nyan' });

  // REDUCE EXAMPLE
  var friendsOfNyanCat = await myAsync.reduce(cat.friends,
    async (catArray, friendId) => {
      var friend = await Friend.findById(friendId);
      if (friend.name !== 'Long cat') {
        catArray.push(friend.name);
      }
    }, []);
  // Assuming Long Cat was a friend of Nyan Cat...
  assert(friendsOfNyanCat.length === (cat.friends.length - 1));
}

This is because of using integer indices (ix selects those by label over -3 rather than position, and this is by design: see integer indexing in pandas "gotchas"*).

*In newer versions of pandas prefer loc or iloc to remove the ambiguity of ix as position or label:

df.iloc[-3:]

see the docs.

As Wes points out, in this specific case you should just use tail!

This is very easy to use, just copy-paste the code. You can use your own star image in background.

I have created a variable var userRating. you can use this variable to get value from stars.

You can specify become_method to override the default method set in ansible.cfg (if any), and which can be set to one of sudo, su, pbrun, pfexec, doas, dzdo, ksu.

- name: I am confused

  become: true
  become_method: su
  become_user: some_user
  register: myidentity

- name: my secret identity
  debug:
    msg: '{{ myidentity.stdout }}'

Should display

I just discovered sshj, which seems to have a much more concise API than JSCH (but it requires Java 6). The documentation is mostly by examples-in-the-repo at this point, and usually that's enough for me to look elsewhere, but it seems good enough for me to give it a shot on a project I just started.

First paste it into Word, then you can paste it into notepad and it will appear without the quotes

How about simply:

select distinct c1, c2 from t

or

select c1, c2, count(*)
from t
group by c1, c2

object["property"] = value;

or

object.property = value;

Object and Array in JavaScript are different in terms of usage. Its best if you understand them:

Object vs Array: JavaScript

Running nginx -t through your commandline will issue out a test and append the output with the filepath to the configuration file (with either an error or success message).

Get the keys in the first for loop, sort it, use the sorted result in the 2nd for loop.

var a = new Array();
a['b'] = 1;
a['z'] = 1;
a['a'] = 1;

var b = [];
for (k in a) b.push(k);
b.sort();
for (var i = 0; i < b.length; ++i) alert(b[i]);

As of Jquery 3.0 and above .bind has been deprecated and they prefer using .on instead. As @Blazemonger answered earlier that it may be removed and its for sure that it will be removed. For the older versions .bind would also call .on internally and there is no difference between them. Please also see the api for more detail.

jQuery API documentation for .bind()

Adding margin to align images:

Since we wanted the image to be left-aligned, we added:

img {
  margin-right: auto;
}

Similarly for image to be right-aligned, we can add margin-right: auto;. The snippet shows a demo for both types of alignment.

Good Luck...

I used runas /user:domainuser@domain cmd which opened an elevated prompt successfully.

The accepted answer correctly addresses the OP's question based on his example. However, it only applies when ToList is applied to a concrete collection; it does not hold when the elements of the source sequence have yet to be instantiated (due to deferred execution). In case of the latter, you might get a new set of items each time you call ToList (or enumerate the sequence).

Here is an adaptation of the OP's code to demonstrate this behaviour:

public static void RunChangeList()
{
    var objs = Enumerable.Range(0, 10).Select(_ => new MyObject() { SimpleInt = 0 });
    var whatInt = ChangeToList(objs);   // whatInt gets 0
}

public static int ChangeToList(IEnumerable<MyObject> objects)
{
    var objectList = objects.ToList();
    objectList.First().SimpleInt = 5;
    return objects.First().SimpleInt;
}

Whilst the above code may appear contrived, this behaviour can appear as a subtle bug in other scenarios. See my other example for a situation where it causes tasks to get spawned repeatedly.

Only solution that works was create a new conda env with the name you want (you will, unfortunately, delete the old one to keep the name). Then create a new env with a new python version and re-run your install.sh script with the conda/pip installs (or the yaml file or whatever you use to keep your requirements):

conda remove --name original_name --all
conda create --name original_name python=3.8
sh install.sh  # or whatever you usually do to install dependencies

doing conda install python=3.8 doesn't work for me. Also, why do you want 3.6? Move forward with the word ;)

Note bellow doesn't work:

If you want to update the conda version of your previous env what you can also do is the following (more complicated than it should be because you cannot rename envs in conda):

1. create a temporary new location for your current env:

conda create --name temporary_env_name --clone original_env_name

2. delete the original env (so that the new env can have that name):

conda deactivate
conda remove --name original_env_name --all # or its alias: `conda env remove --name original_env_name`

3. then create the new empty env with the python version you want and clone the original env:

conda create --name original_env_name python=3.8 --clone temporary_env_name

A simple 4on4 pasting function that works-

def paste(background,foreground,pos=(0,0)):
    #get position and crop pasting area if needed
    x = pos[0]
    y = pos[1]
    bgWidth = background.shape[0]
    bgHeight = background.shape[1]
    frWidth = foreground.shape[0]
    frHeight = foreground.shape[1]
    width = bgWidth-x
    height = bgHeight-y
    if frWidth<width:
        width = frWidth
    if frHeight<height:
        height = frHeight
    # normalize alpha channels from 0-255 to 0-1
    alpha_background = background[x:x+width,y:y+height,3] / 255.0
    alpha_foreground = foreground[:width,:height,3] / 255.0
    # set adjusted colors
    for color in range(0, 3):
        fr = alpha_foreground * foreground[:width,:height,color]
        bg = alpha_background * background[x:x+width,y:y+height,color] * (1 - alpha_foreground)
        background[x:x+width,y:y+height,color] = fr+bg
    # set adjusted alpha and denormalize back to 0-255
    background[x:x+width,y:y+height,3] = (1 - (1 - alpha_foreground) * (1 - alpha_background)) * 255
    return background

I feel this question need a bit more details. My answer is inspired from the Android Programming, The Big Nerd Ranch Guide (2nd edition).

By default, JavaScript is off in WebView. You do not always need to have it on, but for some apps, might do require it.

Loading the URL has to be done after configuring the WebView, so you do that last. Before that, you turn JavaScript on by calling getSettings() to get an instance of WebSettings and calling WebSettings.setJavaScriptEnabled(true). WebSettings is the first of the three ways you can modify your WebView. It has various properties you can set, like the user agent string and text size.

After that, you configure your WebViewClient. WebViewClient is an event interface. By providing your own implementation of WebViewClient, you can respond to rendering events. For example, you could detect when the renderer starts loading an image from a particular URL or decide whether to resubmit a POST request to the server.

WebViewClient has many methods you can override, most of which you will not deal with. However, you do need to replace the default WebViewClient’s implementation of shouldOverrideUrlLoading(WebView, String). This method determines what will happen when a new URL is loaded in the WebView, like by pressing a link. If you return true, you are saying, “Do not handle this URL, I am handling it myself.” If you return false, you are saying, “Go ahead and load this URL, WebView, I’m not doing anything with it.”

The default implementation fires an implicit intent with the URL, just like you did earlier. Now, though, this would be a severe problem. The first thing some Web Applications does is redirect you to the mobile version of the website. With the default WebViewClient, that means that you are immediately sent to the user’s default web browser. This is just what you are trying to avoid. The fix is simple – just override the default implementation and return false.

Use WebChromeClient to spruce things up Since you are taking the time to create your own WebView, let’s spruce it up a bit by adding a progress bar and updating the toolbar’s subtitle with the title of the loaded page.

To hook up the ProgressBar, you will use the second callback on WebView: WebChromeClient.

WebViewClient is an interface for responding to rendering events; WebChromeClient is an event interface for reacting to events that should change elements of chrome around the browser. This includes JavaScript alerts, favicons, and of course updates for loading progress and the title of the current page.

Hook it up in onCreateView(…). Using WebChromeClient to spruce things up Progress updates and title updates each have their own callback method, onProgressChanged(WebView, int) and onReceivedTitle(WebView, String). The progress you receive from onProgressChanged(WebView, int) is an integer from 0 to 100. If it is 100, you know that the page is done loading, so you hide the ProgressBar by setting its visibility to View.GONE.

Cut the long story short: With relative layout you position elements inside the layout.

1. create a new RelativeLayout.LayoutParams

   RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(...)
   

   (whatever... fill parent or wrap content, absolute numbers if you must, or reference to an XML resource)

2. Add rules: Rules refer to the parent or to other "brothers" in the hierarchy.

   lp.addRule(RelativeLayout.BELOW, someOtherView.getId())
   lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT)
   

3. Just apply the layout params: The most 'healthy' way to do that is:

   parentLayout.addView(myView, lp)
   

Watch out: Don't change layout from the layout callbacks. It is tempting to do so because this is when views get their actual sizes. However, in that case, unexpected results are expected.

While I like the first answer and I hate eval, I'd like to add that there's another way (similar to eval) so if you can go around it and not use it, you better do. But in some cases you may want to call some javascript code before or after some ajax call and if you have this code in a custom attribute instead of ajax you could use this:

    var executeBefore = $(el).attr("data-execute-before-ajax");
    if (executeBefore != "") {
        var fn = new Function(executeBefore);
        fn();
    }

Or eventually store this in a function cache if you may need to call it multiple times.

Again - don't use eval or this method if you have another way to do that.

You can use normal CSS selectors to select an element by name using jquery. Like this:

Button Code
<button type="button" name="mybutton">Click Me!</button>

Selector & Event Bind Code
$("button[name='mybutton']").click(function() {});

You can simply use a '+' to convert the result to a number.

var x = 22.032423;
x = +x.toFixed(2); // x = 22.03

A quick and easy way is to use jQuery and do this:

var $eles = $(":input[name^='q1_']").css("color","yellow");

That will grab all elements whose name attribute starts with 'q1_'. To convert the resulting collection of jQuery objects to a DOM collection, do this:

var DOMeles = $eles.get();

see http://api.jquery.com/attribute-starts-with-selector/

In pure DOM, you could use getElementsByTagName to grab all input elements, and loop through the resulting array. Elements with name starting with 'q1_' get pushed to another array:

var eles = [];
var inputs = document.getElementsByTagName("input");
for(var i = 0; i < inputs.length; i++) {
    if(inputs[i].name.indexOf('q1_') == 0) {
        eles.push(inputs[i]);
    }
}

getch () function returns two keycodes for arrow keys (and some other special keys), as mentioned in the comment by FatalError. It returns either 0 (0x00) or 224 (0xE0) first, and then returns a code identifying the key that was pressed.

For the arrow keys, it returns 224 first followed by 72 (up), 80 (down), 75 (left) and 77 (right). If the num-pad arrow keys (with NumLock off) are pressed, getch () returns 0 first instead of 224.

Please note that getch () is not standardized in any way, and these codes might vary from compiler to compiler. These codes are returned by MinGW and Visual C++ on Windows.

A handy program to see the action of getch () for various keys is:

#include <stdio.h>
#include <conio.h>

int main ()
{
    int ch;

    while ((ch = _getch()) != 27) /* 27 = Esc key */
    {
        printf("%d", ch);
        if (ch == 0 || ch == 224)
            printf (", %d", _getch ()); 
        printf("\n");
    }

    printf("ESC %d\n", ch);

    return (0);
}

This works for MinGW and Visual C++. These compilers use the name _getch () instead of getch () to indicate that it is a non-standard function.

So, you may do something like:

ch = _getch ();
if (ch == 0 || ch == 224)
{
    switch (_getch ())
    {
        case 72:
            /* Code for up arrow handling */
            break;

        case 80:
            /* Code for down arrow handling */
            break;

        /* ... etc ... */
    }
}

While I agree with the other answers regarding the RoleManager, I would advice to examine the possibility to implement Authorization through Claims (Expressing Roles as Claims).

Starting with the .NET Framework 4.5, Windows Identity Foundation (WIF) has been fully integrated into the .NET Framework.

In claims-aware applications, the role is expressed by a role claim type that should be available in the token. When the IsInRole() method is called, there is a check made to see if the current user has that role.

The role claim type is expressed using the following URI: "http://schemas.microsoft.com/ws/2008/06/identity/claims/role"

So instead of using the RoleManager, you can "add a user to a role" from the UserManager, doing something like this:

var um = new UserManager();
um.AddClaimAsync(1, new Claim("http://schemas.microsoft.com/ws/2008/06/identity/claims/role", "administrator"));

With the above lines you have added a role claim with the value "administrator" to the user with the id "1"...

Claims authorization, as suggested by MSFT, can simplify and increase the performance of authentication and authorization processes eliminating some back-end queries every time authorization takes place.

Using Claims you may not need the RoleStore anymore. (AspNetRoles, AspNetUserRoles)

In most situations, git fetch should do what you want, which is 'get anything new from the remote repository and put it in your local copy without merging to your local branches'. git fetch --tags does exactly that, except that it doesn't get anything except new tags.

In that sense, git fetch --tags is in no way a superset of git fetch. It is in fact exactly the opposite.

git pull, of course, is nothing but a wrapper for a git fetch <thisrefspec>; git merge. It's recommended that you get used to doing manual git fetching and git mergeing before you make the jump to git pull simply because it helps you understand what git pull is doing in the first place.

That being said, the relationship is exactly the same as with git fetch. git pull is the superset of git pull --tags.

It is used in the project PureMVC for TypeScript I'm working on at the time using Webstorm.

Launch the program "Run" (Windows Vista/7/8: type it in the start menu search bar) and type: C:\windows\assembly\GAC_MSIL

Then move to the parent folder (Windows Vista/7/8: by clicking on it in the explorer bar) to see all the GAC files in a normal explorer window. You can now copy, add and remove files as everywhere else.

Summernote converts your uploaded images to a base64 encoded string by default, you can process this string or as other fellows mentioned you can upload images using onImageUpload callback. You can take a look at this gist which I modified a bit to adapt laravel csrf token here. But that did not work for me and I had no time to find out why! Instead, I solved it via a server-side solution based on this blog post. It gets the output of the summernote and then it will upload the images and updates the final markdown HTML.

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;

Route::get('/your-route-to-editor', function () {
    return view('your-view');
});

Route::post('/your-route-to-processor', function (Request $request) {

       $this->validate($request, [
           'editordata' => 'required',
       ]);

       $data = $request->input('editordata');

       //loading the html data from the summernote editor and select the img tags from it
       $dom = new \DomDocument();
       $dom->loadHtml($data, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);    
       $images = $dom->getElementsByTagName('img');
       
       foreach($images as $k => $img){
           //for now src attribute contains image encrypted data in a nonsence string
           $data = $img->getAttribute('src');
           //getting the original file name that is in data-filename attribute of img
           $file_name = $img->getAttribute('data-filename');
           //extracting the original file name and extension
           $arr = explode('.', $file_name);
           $upload_base_directory = 'public/';

           $original_file_name='time()'.$k;
           $original_file_extension='png';

           if (sizeof($arr) ==  2) {
                $original_file_name = $arr[0];
                $original_file_extension = $arr[1];
           }
           else
           {
                //the file name contains extra . in itself
                $original_file_name = implode("_",array_slice($arr,0,sizeof($arr)-1));
                $original_file_extension = $arr[sizeof($arr)-1];
           }

           list($type, $data) = explode(';', $data);
           list(, $data)      = explode(',', $data);

           $data = base64_decode($data);

           $path = $upload_base_directory.$original_file_name.'.'.$original_file_extension;

           //uploading the image to an actual file on the server and get the url to it to update the src attribute of images
           Storage::put($path, $data);

           $img->removeAttribute('src');       
           //you can remove the data-filename attribute here too if you want.
           $img->setAttribute('src', Storage::url($path));
           // data base stuff here :
           //saving the attachments path in an array
       }

       //updating the summernote WYSIWYG markdown output.
       $data = $dom->saveHTML();

       // data base stuff here :
       // save the post along with it attachments array
       return view('your-preview-page')->with(['data'=>$data]);

});

I was very reluctant to choose the path I finally decide to take because of many answers. While they add more understanding to what is SQL and its principles, I decided to become an outlaw. I was also hesitant to post my findings as for some it's more important to vent frustration to someone breaking the rules rather than understanding that there are very few universal truthes.

I have tested it extensively and, in my specific case, it was way more efficient than both using array type (generously offered by PostgreSQL) or querying another table.

Here is my answer: I have successfully implemented a list into a single field in PostgreSQL, by making use of the fixed length of each item of the list. Let say each item is a color as an ARGB hex value, it means 8 char. So you can create your array of max 10 items by multiplying by the length of each item:

ALTER product ADD color varchar(80)

In case your list items length differ you can always fill the padding with \0

NB: Obviously this is not necessarily the best approach for hex number since a list of integers would consume less storage but this is just for the purpose of illustrating this idea of array by making use of a fixed length allocated to each item.

The reason why: 1/ Very convenient: retrieve item i at substring i*n, (i +1)*n. 2/ No overhead of cross tables queries. 3/ More efficient and cost-saving on the server side. The list is like a mini blob that the client will have to split.

While I respect people following rules, many explanations are very theoretical and often fail to acknowledge that, in some specific cases, especially when aiming for cost optimal with low-latency solutions, some minor tweaks are more than welcome.

"God forbid that it is violating some holy sacred principle of SQL": Adopting a more open-minded and pragmatic approach before reciting the rules is always the way to go. Else you might end up like a candid fanatic reciting the Three Laws of Robotics before being obliterated by Skynet

I don't pretend that this solution is a breakthrough, nor that it is ideal in term of readability and database flexibility, but it can certainly give you an edge when it comes to latency.

I believe you intended it more this way:

foreach (DataTable table in ds.Tables)
{
    foreach (DataRow dr in table.Rows)
    {
        DateTime TaskStart = DateTime.Parse(dr["TaskStart"].ToString());
        TaskStart.ToString("dd-MMMM-yyyy");
        rpt.SetParameterValue("TaskStartDate", TaskStart);
    }
}

You always accessed your first row in your dataset.

add a folder animator into res folder. (the name must be animator). Add an animator resource file. For example res/animator/fade.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <objectAnimator
        android:propertyName="backgroundColor"
        android:duration="1000"
        android:valueFrom="#000000"
        android:valueTo="#FFFFFF"
        android:startOffset="0"
        android:repeatCount="-1"
        android:repeatMode="reverse" />
</set>

Inside Activity java file, call this

View v = getWindow().getDecorView().findViewById(android.R.id.content);
AnimatorSet set = (AnimatorSet) AnimatorInflater.loadAnimator(this, R.animator.fade);
set.setTarget(v);
set.start();

var canvas = document.getElementById('canvas');
var ctx    = canvas.getContext('2d');
var video  = document.getElementById('video');

video.addEventListener('play', function () {
    var $this = this; //cache
    (function loop() {
        if (!$this.paused && !$this.ended) {
            ctx.drawImage($this, 0, 0);
            setTimeout(loop, 1000 / 30); // drawing at 30fps
        }
    })();
}, 0);

I guess the above code is self Explanatory, If not drop a comment below, I will try to explain the above few lines of code

Edit :
here's an online example, just for you :)

My experience when using Dapper to connect to MySQL is that it does matter. I changed a non nullable bit(1) to a nullable tinyint(1) by using the following script:

ALTER TABLE TableName MODIFY Setting BOOLEAN null;

Then Dapper started throwing Exceptions. I tried to look at the difference before and after the script. And noticed the bit(1) had changed to tinyint(1).

I then ran:

ALTER TABLE TableName CHANGE COLUMN Setting Setting BIT(1) NULL DEFAULT NULL;

Which solved the problem.

First you need to turn on virtualization on your machine. To do that, restart your machine. Press F2. Goto BIOS. Make Virtualization Enabled. Press F10. Start windows. Now, goto Extras folder of Android installation folder and find intel-haxm-android.exe. Run it. Start Android Studio. Now, it should allow you to run your program using emulator.

You can do this in 2 steps:

1: Change the input type(In your EditText field) in the layout file to android:inputType="number"

2: Use int a = Integer.parseInt(yourEditTextObject.getText().toString());

Note for Windows users, the jars should be separated by ; and not :.

for example: javac -cp external_libs\lib1.jar;other\lib2.jar;

Depending on what language you are programming in, you can use a function to replace double quotes with two double quotes.

For example in PHP that would be:

str_replace('"', '""', $string);

If you are trying to do that using SQL only, maybe REPLACE() is what you are looking for.

So your query would look something like this:

"UPDATE Table SET columnname = '" & REPLACE(@wstring, '"', '""') & "' where ... blah ... blah "

I found this thread when I was searching for an answer to the same question. While I realize that it's a late answer, I thought I'd contribute it in case it's useful to anyone else:

Check this article. It gives you several ways to do this, via the PropertyPlaceholderConfigurer which supports external properties (via the systemPropertiesMode property).

The setting was disabled in Jupyter 5.X and higher by adding below code

pylab = Unicode('disabled', config=True,
    help=_("""
    DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
    """)
)

@observe('pylab')
def _update_pylab(self, change):
    """when --pylab is specified, display a warning and exit"""
    if change['new'] != 'warn':
        backend = ' %s' % change['new']
    else:
        backend = ''
    self.log.error(_("Support for specifying --pylab on the command line has been removed."))
    self.log.error(
        _("Please use `%pylab{0}` or `%matplotlib{0}` in the notebook itself.").format(backend)
    )
    self.exit(1)

And in previous versions it has majorly been a warning. But this not a big issue because Jupyter uses concepts of kernels and you can find kernel for your project by running below command

$ jupyter kernelspec list
Available kernels:
  python3    /Users/tarunlalwani/Documents/Projects/SO/notebookinline/bin/../share/jupyter/kernels/python3

This gives me the path to the kernel folder. Now if I open the /Users/tarunlalwani/Documents/Projects/SO/notebookinline/bin/../share/jupyter/kernels/python3/kernel.json file, I see something like below

{
 "argv": [
  "python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}",
 ],
 "display_name": "Python 3",
 "language": "python"
}

So you can see what command is executed to launch the kernel. So if you run the below command

$ python -m ipykernel_launcher --help
IPython: an enhanced interactive Python shell.

Subcommands
-----------

Subcommands are launched as `ipython-kernel cmd [args]`. For information on
using subcommand 'cmd', do: `ipython-kernel cmd -h`.

install
    Install the IPython kernel

Options
-------

Arguments that take values are actually convenience aliases to full
Configurables, whose aliases are listed on the help line. For more information
on full configurables, see '--help-all'.

....
--pylab=<CaselessStrEnum> (InteractiveShellApp.pylab)
    Default: None
    Choices: ['auto', 'agg', 'gtk', 'gtk3', 'inline', 'ipympl', 'nbagg', 'notebook', 'osx', 'pdf', 'ps', 'qt', 'qt4', 'qt5', 'svg', 'tk', 'widget', 'wx']
    Pre-load matplotlib and numpy for interactive use, selecting a particular
    matplotlib backend and loop integration.
--matplotlib=<CaselessStrEnum> (InteractiveShellApp.matplotlib)
    Default: None
    Choices: ['auto', 'agg', 'gtk', 'gtk3', 'inline', 'ipympl', 'nbagg', 'notebook', 'osx', 'pdf', 'ps', 'qt', 'qt4', 'qt5', 'svg', 'tk', 'widget', 'wx']
    Configure matplotlib for interactive use with the default matplotlib
    backend.
...    
To see all available configurables, use `--help-all`

So now if we update our kernel.json file to

{
 "argv": [
  "python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}",
  "--pylab",
  "inline"
 ],
 "display_name": "Python 3",
 "language": "python"
}

And if I run jupyter notebook the graphs are automatically inline

Note the below approach also still works, where you create a file on below path

~/.ipython/profile_default/ipython_kernel_config.py

c = get_config()
c.IPKernelApp.matplotlib = 'inline'

But the disadvantage of this approach is that this is a global impact on every environment using python. You can consider that as an advantage also if you want to have a common behaviour across environments with a single change.

So choose which approach you would like to use based on your requirement

I've had to do this recently on the API 23 emulator, and followed this guide. It works for API 23 emulator, so you shouldn't have a problem.

Download the GAPPS Package

Next we need to pull down the appropriate Google Apps package that matches our Android AVD version. In this case we’ll be using the 'gapps-lp-20141109-signed.zip' package. You can download that file from BasketBuild here.

[pyoor@localhost]$ md5sum gapps-lp-20141109-signed.zip

In order to install Google Play, we’ll need to push the following 4 APKs to our AVD (located in ./system/priv-app/):

GmsCore.apk, GoogleServicesFramework.apk, GoogleLoginService.apk, Phonesky.apk

[pyoor@localhost]$ unzip -j gapps-lp-20141109-signed.zip \
system/priv-app/GoogleServicesFramework/GoogleServicesFramework.apk \
system/priv-app/GoogleLoginService/GoogleLoginService.apk \
system/priv-app/Phonesky/Phonesky.apk \
system/priv-app/GmsCore/GmsCore.apk -d ./

Push APKs to the Emulator

With our APKs extracted, let’s launch our AVD using the following command.

[pyoor@localhost tools]$ ./emulator @<YOUR_DEVICE_NAME> -no-boot-anim

This may take several minutes the first time as the AVD is created. Once started, we need to remount the AVDs system partition as read/write so that we can push our packages onto the device.

[pyoor@localhost]$ cd ~/android-sdk/platform-tools/
[pyoor@localhost platform-tools]$ ./adb remount

Next, push the APKs to our AVD:

[pyoor@localhost platform-tools]$ ./adb push GmsCore.apk /system/priv-app/
[pyoor@localhost platform-tools]$ ./adb push GoogleServicesFramework.apk /system/priv-app/
[pyoor@localhost platform-tools]$ ./adb push GoogleLoginService.apk /system/priv-app/
[pyoor@localhost platform-tools]$ ./adb push Phonesky.apk /system/priv-app

Profit!

And finally, reboot the emualator using the following commands:

[pyoor@localhost platform-tools]$ ./adb shell stop && ./adb shell start

Once the emulator restarts, we should see the Google Play package appear within the menu launcher. After associating a Google account with this AVD we now have a fully working version of Google Play running under our emulator.

Wifi is not available on the emulator if you are using below of API level 25.

When using an AVD with API level 25 or higher, the emulator provides a simulated Wi-Fi access point ("AndroidWifi"), and Android automatically connects to it.

You can use a pairwise cyclic iterator:

from itertools import izip, cycle, tee

def pairwise(seq):
    a, b = tee(seq)
    next(b)
    return izip(a, b)

for elem, next_elem in pairwise(cycle(li)):
    ...

Similar to @Aaron Digulla's suggestion except that I would suggest a graphics design tool, select the base color, in your case the background color, then adjust the Hue, Saturation and Value. Using this you can create color swatches very easily. Paint.Net is free and I use it all the time for this and also the pay-for-tools will also do this.

This is a very c# type of code:

var bks: Book[] = new Book[2];

In Javascript / Typescript you don't allocate memory up front like that, and that means something completely different. This is how you would do what you want to do:

var bks: Book[] = [];
bks.push(new Book());
bks[0].Author = "vamsee";
bks[0].BookId = 1;
return bks.length;

Now to explain what new Book[2]; would mean. This would actually mean that call the new operator on the value of Book[2]. e.g.:

Book[2] = function (){alert("hey");}
var foo = new Book[2]

and you should see hey. Try it

try this

SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
String string  = dateFormat.format(new Date());
System.out.println(string);

you can create any format see this

Just thought I'd throw this in:

function inArray(val, ary){
  for(var i=0,l=ary.length; i<l; i++){
    if(ary[i] === val){
      return true;
    }
  }
  return false;
}
function removeClassName(classNameS, fromElement){
  var x = classNameS.split(/\s/), s = fromElement.className.split(/\s/), r = [];
  for(var i=0,l=s.length; i<l; i++){
    if(!iA(s[i], x))r.push(s[i]);
  }
  fromElement.className = r.join(' ');
}
function addClassName(classNameS, toElement){
  var s = toElement.className.split(/\s/);
  s.push(c); toElement.className = s.join(' ');
}

From What is Unicode:

Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one.

......

Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language.

So when a computer represents a string, it finds characters stored in the computer of the string through their unique Unicode number and these figures are stored in memory. But you can't directly write the string to disk or transmit the string on network through their unique Unicode number because these figures are just simple decimal number. You should encode the string to byte string, such as UTF-8. UTF-8 is a character encoding capable of encoding all possible characters and it stores characters as bytes (it looks like this). So the encoded string can be used everywhere because UTF-8 is nearly supported everywhere. When you open a text file encoded in UTF-8 from other systems, your computer will decode it and display characters in it through their unique Unicode number. When a browser receive string data encoded UTF-8 from network, it will decode the data to string (assume the browser in UTF-8 encoding) and display the string.

In python3, you can transform string and byte string to each other:

>>> print('??'.encode('utf-8'))
b'\xe4\xb8\xad\xe6\x96\x87'
>>> print(b'\xe4\xb8\xad\xe6\x96\x87'.decode('utf-8'))
?? 

In a word, string is for displaying to humans to read on a computer and byte string is for storing to disk and data transmission.

start it with hover of body than It will start when the mouse first moves on the screen, which is mostly within a second after arrival, the problem here is that it will reverse when out of the screen.

html:hover #animateelementid, body:hover #animateelementid {rotate ....}

thats the best thing I can think of: http://jsfiddle.net/faVLX/

Place the following in your jQuery mouseover event handler:

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

To set both color and size at the same time:

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

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

I created a directive for this (angular stable 1.0.8)

<input type="text" input-disabled="editableInput" />
<button ng-click="editableInput = !editableInput">enable/disable</button>

app.controller("myController", function(){
  $scope.editableInput = false;
});

app.directive("inputDisabled", function(){
  return function(scope, element, attrs){
    scope.$watch(attrs.inputDisabled, function(val){
      if(val)
        element.removeAttr("disabled");
      else
        element.attr("disabled", "disabled");
    });
  }
});

 select p.post_title,m.meta_value sale_price ,n.meta_value   regular_price
    from  wp_postmeta m 
    inner join wp_postmeta n
      on m.post_id  = n.post_id
    inner join wp_posts p
      ON m.post_id=p.id 
    and m.meta_key = '_sale_price'
    and  n.meta_key = '_regular_price'
     AND p.post_type = 'product';



 update  wp_postmeta m 
inner join wp_postmeta n
  on m.post_id  = n.post_id
inner join wp_posts p
  ON m.post_id=p.id 
and m.meta_key = '_sale_price'
and  n.meta_key = '_regular_price'
 AND p.post_type = 'product'
 set m.meta_value = n.meta_value;

This worked for me. Make sure Gradle is not set to offline by unchecking button at File>Settings>Gradle>Offline Work.

Add this to the top level of your build.gradle, nice to have above dependencies

configurations.all {
    resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
}

I made sure my dependencies are written like this:

implementation('com.github.juanmendez:ThatDependency:ThatBranch-SNAPSHOT') {
    changing = true
}

Thereafter, I open the Gradle panel in Android Studio and click the blue circle arrows button. I can always see my updates getting a new fresh copy.

SO if any space is there in your directory path do not forgot to add double inverted commas "".

If I understand you correctly, you want a list of all pictures with the same name (and their different ids) such that their name occurs more than once in the table. I think this will do the trick:

SELECT U.NAME, P.PIC_ID
FROM USERS U, PICTURES P, POSTINGS P1
WHERE U.EMAIL_ID = P1.EMAIL_ID AND P1.PIC_ID = P.PIC_ID AND U.Name IN (
SELECT U.Name 
FROM USERS U, PICTURES P, POSTINGS P1
WHERE U.EMAIL_ID = P1.EMAIL_ID AND P1.PIC_ID = P.PIC_ID AND P.CAPTION LIKE '%car%';
GROUP BY U.Name HAVING COUNT(U.Name) > 1)

I haven't executed it, so there may be a syntax error or two there.

An example statement that uses a sub-select :

select * into MyNewTable
from
(
select 
  * 
from 
[SomeOtherTablename]
where 
  EventStartDatetime >= '01/JAN/2018' 
)
) mysourcedata
;

note that the sub query must be given a name .. any name .. e.g. above example gives the subquery a name of mysourcedata. Without this a syntax error is issued in SQL*server 2012.

The database should reply with a message like: (9999 row(s) affected)

On Mac OS X (MBP), the following (taken from another answer found herein) resolved my issues:

C02L257NDV33:~ jjohnson$ brew install pip
Error: No available formula for pip
Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can:
    sudo easy_install pip
C02L257NDV33:~ jjohnson$ sudo easy_install pip

Clearly the root cause here is having a secondary method by which to install python (in my case Homebrew). Hopefully, the people responsible for the pip script can remedy this issue since its still relevant 2 years after first being reported on Stack Overflow.

If you're using SQL Server, you can set the value of bit fields with 0 and 1

or

'true' and 'false' (yes, using strings)

...your_bit_field='false'... => equivalent to 0

I'm guessing that you're trying to find if a certain value exists inside the array, and if that's the case, you can use Array#include?(value):

a = [1,2,3,4,5]
a.include?(3)   # => true
a.include?(9)   # => false

If you mean something else, check the Ruby Array API

You can also use:

$('#test').context.scrollHeight

DateTime dt1 = this.dateTimePicker1.Value.Date;
DateTime dt2 = this.dateTimePicker2.Value.Date.AddMinutes(1440);
String query = "SELECT * FROM student WHERE sdate BETWEEN '" + dt1 + "' AND '" + dt2 + "'";

To stop the user from getting annoyed when the whole text gets selected every time they try to move the caret using their mouse, you should do this using the focus event, not the click event. The following will do the job and works around a problem in Chrome that prevents the simplest version (i.e. just calling the textarea's select() method in a focus event handler) from working.

jsFiddle: http://jsfiddle.net/NM62A/

Code:

<textarea id="foo">Some text</textarea>

<script type="text/javascript">
    var textBox = document.getElementById("foo");
    textBox.onfocus = function() {
        textBox.select();

        // Work around Chrome's little problem
        textBox.onmouseup = function() {
            // Prevent further mouseup intervention
            textBox.onmouseup = null;
            return false;
        };
    };
</script>

jQuery version:

$("#foo").focus(function() {
    var $this = $(this);
    $this.select();

    // Work around Chrome's little problem
    $this.mouseup(function() {
        // Prevent further mouseup intervention
        $this.unbind("mouseup");
        return false;
    });
});

tl;dr

• "Foo" and "bar" as metasyntactic variables were popularised by MIT and DEC, the first references are in work on LISP and PDP-1 and Project MAC from 1964 onwards.

• Many of these people were in MIT's Tech Model Railroad Club, where we find the first documented use of "foo" in tech circles in 1959 (and a variant in 1958).

• Both "foo" and "bar" (and even "baz") were well known in popular culture, especially from Smokey Stover and Pogo comics, which will have been read by many TMRC members.

• Also, it seems likely the military FUBAR contributed to their popularity.

The use of lone "foo" as a nonsense word is pretty well documented in popular culture in the early 20th century, as is the military FUBAR. (Some background reading: FOLDOC FOLDOC Jargon File Jargon File Wikipedia RFC3092)

OK, so let's find some references.

STOP PRESS! After posting this answer, I discovered this perfect article about "foo" in the Friday 14th January 1938 edition of The Tech ("MIT's oldest and largest newspaper & the first newspaper published on the web"), Volume LVII. No. 57, Price Three Cents:

On Foo-ism

The Lounger thinks that this business of Foo-ism has been carried too far by its misguided proponents, and does hereby and forthwith take his stand against its abuse. It may be that there's no foo like an old foo, and we're it, but anyway, a foo and his money are some party. (Voice from the bleachers- "Don't be foo-lish!")

As an expletive, of course, "foo!" has a definite and probably irreplaceable position in our language, although we fear that the excessive use to which it is currently subjected may well result in its falling into an early (and, alas, a dark) oblivion. We say alas because proper use of the word may result in such happy incidents as the following.

It was an 8.50 Thermodynamics lecture by Professor Slater in Room 6-120. The professor, having covered the front side of the blackboard, set the handle that operates the lift mechanism, turning meanwhile to the class to continue his discussion. The front board slowly, majestically, lifted itself, revealing the board behind it, and on that board, writ large, the symbols that spelled "FOO"!

The Tech newspaper, a year earlier, the Letter to the Editor, September 1937:

By the time the train has reached the station the neophytes are so filled with the stories of the glory of Phi Omicron Omicron, usually referred to as Foo, that they are easy prey.

...

It is not that I mind having lost my first four sons to the Grand and Universal Brotherhood of Phi Omicron Omicron, but I do wish that my fifth son, my baby, should at least be warned in advance.

Hopefully yours,

Indignant Mother of Five.

And The Tech in December 1938:

General trend of thought might be best interpreted from the remarks made at the end of the ballots. One vote said, '"I don't think what I do is any of Pulver's business," while another merely added a curt "Foo."

The first documented "foo" in tech circles is probably 1959's Dictionary of the TMRC Language:

FOO: the sacred syllable (FOO MANI PADME HUM); to be spoken only when under inspiration to commune with the Deity. Our first obligation is to keep the Foo Counters turning.

These are explained at FOLDOC. The dictionary's compiler Pete Samson said in 2005:

Use of this word at TMRC antedates my coming there. A foo counter could simply have randomly flashing lights, or could be a real counter with an obscure input.

And from 1996's Jargon File 4.0.0:

Earlier versions of this lexicon derived 'baz' as a Stanford corruption of bar. However, Pete Samson (compiler of the TMRC lexicon) reports it was already current when he joined TMRC in 1958. He says "It came from "Pogo". Albert the Alligator, when vexed or outraged, would shout 'Bazz Fazz!' or 'Rowrbazzle!' The club layout was said to model the (mythical) New England counties of Rowrfolk and Bassex (Rowrbazzle mingled with (Norfolk/Suffolk/Middlesex/Essex)."

A year before the TMRC dictionary, 1958's MIT Voo Doo Gazette ("Humor suplement of the MIT Deans' office") (PDF) mentions Foocom, in "The Laws of Murphy and Finagle" by John Banzhaf (an electrical engineering student):

Further research under a joint Foocom and Anarcom grant expanded the law to be all embracing and universally applicable: If anything can go wrong, it will!

Also 1964's MIT Voo Doo (PDF) references the TMRC usage:

Yes! I want to be an instant success and snow customers. Send me a degree in: ...

• Foo Counters

• Foo Jung

Let's find "foo", "bar" and "foobar" published in code examples.

So, Jargon File 4.4.7 says of "foobar":

Probably originally propagated through DECsystem manuals by Digital Equipment Corporation (DEC) in 1960s and early 1970s; confirmed sightings there go back to 1972.

The first published reference I can find is from February 1964, but written in June 1963, The Programming Language LISP: its Operation and Applications by Information International, Inc., with many authors, but including Timothy P. Hart and Michael Levin:

Thus, since "FOO" is a name for itself, "COMITRIN" will treat both "FOO" and "(FOO)" in exactly the same way.

Also includes other metasyntactic variables such as: FOO CROCK GLITCH / POOT TOOR / ON YOU / SNAP CRACKLE POP / X Y Z

I expect this is much the same as this next reference of "foo" from MIT's Project MAC in January 1964's AIM-064, or LISP Exercises by Timothy P. Hart and Michael Levin:

car[((FOO . CROCK) . GLITCH)]

It shares many other metasyntactic variables like: CHI / BOSTON NEW YORK / SPINACH BUTTER STEAK / FOO CROCK GLITCH / POOT TOOP / TOOT TOOT / ISTHISATRIVIALEXCERCISE / PLOOP FLOT TOP / SNAP CRACKLE POP / ONE TWO THREE / PLANE SUB THRESHER

For both "foo" and "bar" together, the earliest reference I could find is from MIT's Project MAC in June 1966's AIM-098, or PDP-6 LISP by none other than Peter Samson:

EXPLODE, like PRIN1, inserts slashes, so (EXPLODE (QUOTE FOO/ BAR)) PRIN1's as (F O O // / B A R) or PRINC's as (F O O / B A R).

Some more recallations.

@Walter Mitty recalled on this site in 2008:

I second the jargon file regarding Foo Bar. I can trace it back at least to 1963, and PDP-1 serial number 2, which was on the second floor of Building 26 at MIT. Foo and Foo Bar were used there, and after 1964 at the PDP-6 room at project MAC.

John V. Everett recalls in 1996:

When I joined DEC in 1966, foobar was already being commonly used as a throw-away file name. I believe fubar became foobar because the PDP-6 supported six character names, although I always assumed the term migrated to DEC from MIT. There were many MIT types at DEC in those days, some of whom had worked with the 7090/7094 CTSS. Since the 709x was also a 36 bit machine, foobar may have been used as a common file name there.

Foo and bar were also commonly used as file extensions. Since the text editors of the day operated on an input file and produced an output file, it was common to edit from a .foo file to a .bar file, and back again.

It was also common to use foo to fill a buffer when editing with TECO. The text string to exactly fill one disk block was IFOO$HXA127GA$$. Almost all of the PDP-6/10 programmers I worked with used this same command string.

Daniel P. B. Smith in 1998:

Dick Gruen had a device in his dorm room, the usual assemblage of B-battery, resistors, capacitors, and NE-2 neon tubes, which he called a "foo counter." This would have been circa 1964 or so.

Robert Schuldenfrei in 1996:

The use of FOO and BAR as example variable names goes back at least to 1964 and the IBM 7070. This too may be older, but that is where I first saw it. This was in Assembler. What would be the FORTRAN integer equivalent? IFOO and IBAR?

Paul M. Wexelblat in 1992:

The earliest PDP-1 Assembler used two characters for symbols (18 bit machine) programmers always left a few words as patch space to fix problems. (Jump to patch space, do new code, jump back) That space conventionally was named FU: which stood for Fxxx Up, the place where you fixed Fxxx Ups. When spoken, it was known as FU space. Later Assemblers ( e.g. MIDAS allowed three char tags so FU became FOO, and as ALL PDP-1 programmers will tell you that was FOO space.

Bruce B. Reynolds in 1996:

On the IBM side of FOO(FU)BAR is the use of the BAR side as Base Address Register; in the middle 1970's CICS programmers had to worry out the various xxxBARs...I think one of those was FRACTBAR...

Here's a straight IBM "BAR" from 1955.

Problem solved :)

Short answer:

Only use WITH (NOLOCK) in SELECT statement on tables that have a clustered index.

Long answer:

WITH(NOLOCK) is often exploited as a magic way to speed up database reads.

The result set can contain rows that have not yet been committed, that are often later rolled back.

If WITH(NOLOCK) is applied to a table that has a non-clustered index then row-indexes can be changed by other transactions as the row data is being streamed into the result-table. This means that the result-set can be missing rows or display the same row multiple times.

READ COMMITTED adds an additional issue where data is corrupted within a single column where multiple users change the same cell simultaneously.

import numpy as np
import pandas as pd
df = pd.DataFrame()
column_names = ['x','y','z','mean']
for col in column_names: 
    df[col] = np.random.randint(0,100, size=10000)

You can try out the following solutions :

Solution 1:

df = df[ ['mean'] + [ col for col in df.columns if col != 'mean' ] ]

Solution 2:

df = df[['mean', 'x', 'y', 'z']]

Solution 3:

col = df.pop("mean")
df = df.insert(0, col.name, col)

Solution 4:

df.set_index(df.columns[-1], inplace=True)
df.reset_index(inplace=True)

Solution 5:

cols = list(df)
cols = [cols[-1]] + cols[:-1]
df = df[cols]

solution 6:

order = [1,2,3,0] # setting column's order
df = df[[df.columns[i] for i in order]]

In C++11, this is the preferred way:

std::vector<X> f();

That is, return by value.

With C++11, std::vector has move-semantics, which means the local vector declared in your function will be moved on return and in some cases even the move can be elided by the compiler.

You need to CAST the ParentId as an nvarchar, so that the output is always the same data type.

Named parameters are not supported by JPA in native queries, only for JPQL. You must use positional parameters.

Named parameters follow the rules for identifiers defined in Section 4.4.1. The use of named parameters applies to the Java Persistence query language, and is not defined for native queries. Only positional parameter binding may be portably used for native queries.

So, use this

Query q = em.createNativeQuery("SELECT count(*) FROM mytable where username = ?1");
q.setParameter(1, "test");

While JPA specification doesn't support named parameters in native queries, some JPA implementations (like Hibernate) may support it

Native SQL queries support positional as well as named parameters

However, this couples your application to specific JPA implementation, and thus makes it unportable.

For those of you running into the DirectoryNotFoundException, add this check:

I use BC3 for my git diff, but I'd also add vscode to the list of useful git diff tools. Some users prefer vscode over vs ide experience.

Using VS Code for Git Diff

git config --global diff.tool vscode
git config --global difftool.vscode.cmd "code --wait --diff $LOCAL $REMOTE"

In practice, the models are used as follows.

In discriminative models, to predict the label y from the training example x, you must evaluate:

which merely chooses what is the most likely class y considering x. It's like we were trying to model the decision boundary between the classes. This behavior is very clear in neural networks, where the computed weights can be seen as a complexly shaped curve isolating the elements of a class in the space.

Now, using Bayes' rule, let's replace the in the equation by . Since you are just interested in the arg max, you can wipe out the denominator, that will be the same for every y. So, you are left with

which is the equation you use in generative models.

While in the first case you had the conditional probability distribution p(y|x), which modeled the boundary between classes, in the second you had the joint probability distribution p(x, y), since p(x | y) p(y) = p(x, y), which explicitly models the actual distribution of each class.

With the joint probability distribution function, given a y, you can calculate ("generate") its respective x. For this reason, they are called "generative" models.

SQL - Structured Query Language. It is declarative computer language aimed at querying relational databases.

MySQL is a relational database - a piece of software optimized for data storage and retrieval. There are many such databases - Oracle, Microsoft SQL Server, SQLite and many others are examples of such.

ECMAscript edition 5 also offers you the neat methods Object.keys() and Object.getOwnPropertyNames().

So

Object.keys( buttons );  // ['button1', 'button2'];

In one word: no. The only way to stretch an image is with the <img> tag. You'll have to be creative.

This used to be true in 2008, when the answer was written. Today modern browsers support background-size which solves this problem. Beware that IE8 doesn't support it.

Had the same problem with embeded youtube iframe (Translations were used for centering iframe element). None of the solutions above worked until tried reset css filters and magic happened.

Structure:

<div class="translate">
     <iframe/>
</div>

Style [before]

.translate {
  transform: translateX(-50%);
  -webkit-transform: translateX(-50%);
}

Style [after]

.translate {
  transform: translateX(-50%);
  -webkit-transform: translateX(-50%);
  filter: blur(0);
  -webkit-filter: blur(0);
}

You can use exp(x) function of math library, which is same as e^x. Hence you may write your code as:

import math
x.append(1 - math.exp( -0.5 * (value1*value2)**2))

I have modified the equation by replacing 1/2 as 0.5. Else for Python <2.7, we'll have to explicitly type cast the division value to float because Python round of the result of division of two int as integer. For example: 1/2 gives 0 in python 2.7 and below.

I wonder why String.prototype.concat is not getting any love. In my tests (assuming you already have an array of strings), it outperforms all other methods.

perf.link test

Test code:

const numStrings = 100;
const strings = [...new Array(numStrings)].map(() => Math.random().toString(36).substring(6));

const concatReduce = (strs) => strs.reduce((a, b) => a + b);

const concatLoop = (strs) => {
  let result = ''
  for (let i = 0; i < strings.length; i++) {
    result += strings[i];
  }
  return result;
}

// Case 1: 52,570 ops/s
concatLoop(strings);

// Case 2: 96,450 ops/s
concatReduce(strings)

// Case 3: 138,020 ops/s
strings.join('')

// Case 4: 169,520 ops/s
''.concat(...strings)

You can put the values as the table's keys. For example:

function addToSet(set, key)
    set[key] = true
end

function removeFromSet(set, key)
    set[key] = nil
end

function setContains(set, key)
    return set[key] ~= nil
end

There's a more fully-featured example here.

I have 2 solutions that seem to work for all combinations of positive and negative x and y.

1) Abuse atan2()

According to the docs atan2 takes parameters y and x in that order. However if you reverse them you can do the following:

double radians = std::atan2(x, y);
double degrees = radians * 180 / M_PI;
if (radians < 0)
{
    degrees += 360; 
}

2) Use atan2() correctly and convert afterwards

double degrees = std::atan2(y, x) * 180 / M_PI;
if (degrees > 90)
{
    degrees = 450 - degrees;
}
else
{
    degrees = 90 - degrees;
}

Simplifying a bit, you can imagine map() doing something like this:

def mymap(func, lst):
    result = []
    for e in lst:
        result.append(func(e))
    return result

As you can see, it takes a function and a list, and returns a new list with the result of applying the function to each of the elements in the input list. I said "simplifying a bit" because in reality map() can process more than one iterable:

If additional iterable arguments are passed, function must take that many arguments and is applied to the items from all iterables in parallel. If one iterable is shorter than another it is assumed to be extended with None items.

For the second part in the question: What role does this play in making a Cartesian product? well, map() could be used for generating the cartesian product of a list like this:

lst = [1, 2, 3, 4, 5]

from operator import add
reduce(add, map(lambda i: map(lambda j: (i, j), lst), lst))

... But to tell the truth, using product() is a much simpler and natural way to solve the problem:

from itertools import product
list(product(lst, lst))

Either way, the result is the cartesian product of lst as defined above:

[(1, 1), (1, 2), (1, 3), (1, 4), (1, 5),
 (2, 1), (2, 2), (2, 3), (2, 4), (2, 5),
 (3, 1), (3, 2), (3, 3), (3, 4), (3, 5),
 (4, 1), (4, 2), (4, 3), (4, 4), (4, 5),
 (5, 1), (5, 2), (5, 3), (5, 4), (5, 5)]

Sure, a Linked List is a bit confusing for programming n00bs, pretty much the temptation is to look at it as Russian Dolls, because that's what it seems like, a LinkedList Object in a LinkedList Object. But that's a touch difficult to visualize, instead look at it like a computer.

LinkedList = Data + Next Member

Where it's the last member of the list if next is NULL

So a 5 member LinkedList would be:

LinkedList(Data1, LinkedList(Data2, LinkedList(Data3, LinkedList(Data4, LinkedList(Data5, NULL)))))

But you can think of it as simply:

Data1 -> Data2 -> Data3 -> Data4 -> Data5 -> NULL

So, how do we find the end of this? Well, we know that the NULL is the end so:

public void append(LinkedList myNextNode) {
  LinkedList current = this; //Make a variable to store a pointer to this LinkedList
  while (current.next != NULL) { //While we're not at the last node of the LinkedList
    current = current.next; //Go further down the rabbit hole.
  }
  current.next = myNextNode; //Now we're at the end, so simply replace the NULL with another Linked List!
  return; //and we're done!
}

This is very simple code of course, and it will infinitely loop if you feed it a circularly linked list! But that's the basics.

for me this error was actually caused by a field falsely declared as public instead of private.

while [ "$#" -gt 0 ]; do
  case "$1" in
    -n) name="$2"; shift 2;;
    -p) pidfile="$2"; shift 2;;
    -l) logfile="$2"; shift 2;;

    --name=*) name="${1#*=}"; shift 1;;
    --pidfile=*) pidfile="${1#*=}"; shift 1;;
    --logfile=*) logfile="${1#*=}"; shift 1;;
    --name|--pidfile|--logfile) echo "$1 requires an argument" >&2; exit 1;;
    
    -*) echo "unknown option: $1" >&2; exit 1;;
    *) handle_argument "$1"; shift 1;;
  esac
done

This solution:

• handles -n arg and --name=arg
• allows arguments at the end
• shows sane errors if anything is misspelled
• compatible, doesn't use bashisms
• readable, doesn't require maintaining state in a loop

Use chardet https://github.com/chardet/chardet (documentation is short and easy to read).

Install python, then pip install chardet, at last use the command line command.

I tested under GB2312 and it's pretty accurate. (Make sure you have at least a few characters, sample with only 1 character may fail easily).

file is not reliable as you can see.

Who says a file name needs an extension?? take a look on a *nix machine sometime...
I agree with your friend, no trailing slash.

Assuming you're on a Linux or Windows console:

Prompt for password:

mysql -u <username> -p <databasename> < <filename.sql>

Enter password directly (not secure):

mysql -u <username> -p<PlainPassword> <databasename> < <filename.sql>

Example:

mysql -u root -p wp_users < wp_users.sql

mysql -u root -pPassword123 wp_users < wp_users.sql

Ah, and in response to this comment:

I realise I have a typo in my question. I should be like this:

MyImplementedObject obj = new MyImplementedObject ();
if(obj.getClass() == MyObjectInterface.class) System.out.println("true");

MyImplementedObject implements MyObjectInterface So in other words, I am comparing it with its implemented objects.

OK, if you want to check that you can do either:

if(MyObjectInterface.class.isAssignableFrom(obj.getClass()))

or the much more concise

if(obj instanceof MyobjectInterface)

if you are using scribe library, just set up the offline mode, like bonkydog suggested here is the code:

According to book of "The C++ Programming Language 4th Editon" by Bjarne Stroustrup
• const: meaning roughly ‘‘I promise not to change this value’’ (§7.5). This is used primarily to specify interfaces, so that data can be passed to functions without fear of it being modified.
The compiler enforces the promise made by const.
• constexpr: meaning roughly ‘‘to be evaluated at compile time’’ (§10.4). This is used primarily to specify constants, to allow
For example:

const int dmv = 17; // dmv is a named constant
int var = 17; // var is not a constant
constexpr double max1 = 1.4*square(dmv); // OK if square(17) is a constant expression
constexpr double max2 = 1.4*square(var); // error : var is not a constant expression
const double max3 = 1.4*square(var); //OK, may be evaluated at run time
double sum(const vector<double>&); // sum will not modify its argument (§2.2.5)
vector<double> v {1.2, 3.4, 4.5}; // v is not a constant
const double s1 = sum(v); // OK: evaluated at run time
constexpr double s2 = sum(v); // error : sum(v) not constant expression

For a function to be usable in a constant expression, that is, in an expression that will be evaluated by the compiler, it must be defined constexpr.
For example:

constexpr double square(double x) { return x*x; }

To be constexpr, a function must be rather simple: just a return-statement computing a value. A constexpr function can be used for non-constant arguments, but when that is done the result is not a constant expression. We allow a constexpr function to be called with non-constant-expression arguments in contexts that do not require constant expressions, so that we don’t hav e to define essentially the same function twice: once for constant expressions and once for variables.
In a few places, constant expressions are required by language rules (e.g., array bounds (§2.2.5, §7.3), case labels (§2.2.4, §9.4.2), some template arguments (§25.2), and constants declared using constexpr). In other cases, compile-time evaluation is important for performance. Independently of performance issues, the notion of immutability (of an object with an unchangeable state) is an important design concern (§10.4).

To add rows to existing DataTable in Dataset:

DataRow drPartMtl = DSPartMtl.Tables[0].NewRow();
drPartMtl["Group"] = "Group";
drPartMtl["BOMPart"] = "BOMPart";
DSPartMtl.Tables[0].Rows.Add(drPartMtl);

If your not overly worried about the size of the file then it may be easier for you to store the data as a JS object in another file and import it in your . Either synchronously or asynchronously using the syntax <script src="countries.js" async></script>. Saves on you needing to import the file and parse it.

However, i can see why you wouldnt want to rewrite 10000 entries so here's a basic object orientated csv parser i wrote.

function requestCSV(f,c){return new CSVAJAX(f,c);};
function CSVAJAX(filepath,callback)
{
    this.request = new XMLHttpRequest();
    this.request.timeout = 10000;
    this.request.open("GET", filepath, true);
    this.request.parent = this;
    this.callback = callback;
    this.request.onload = function() 
    {
        var d = this.response.split('\n'); /*1st separator*/
        var i = d.length;
        while(i--)
        {
            if(d[i] !== "")
                d[i] = d[i].split(','); /*2nd separator*/
            else
                d.splice(i,1);
        }
        this.parent.response = d;
        if(typeof this.parent.callback !== "undefined")
            this.parent.callback(d);
    };
    this.request.send();
};

Which can be used like this;

var foo = requestCSV("csvfile.csv",drawlines(lines)); 

The first parameter is the file, relative to the position of your html file in this case. The second parameter is an optional callback function the runs when the file has been completely loaded.

If your file has non-separating commmas then it wont get on with this, as it just creates 2d arrays by chopping at returns and commas. You might want to look into regexp if you need that functionality.

//THIS works 

"1234","ABCD" \n
"!@£$" \n

//Gives you 
[
 [
  1234,
  'ABCD'
 ],
 [
  '!@£$'
 ]
]

//This DOESN'T!

"12,34","AB,CD" \n
"!@,£$" \n

//Gives you

[
 [
  '"12',
  '34"',
  '"AB',
  'CD'
 ]
 [
  '"!@',
  '£$'
 ]
]

If your not used to the OO methods; they create a new object (like a number, string, array) with their own local functions and variables via a 'constructor' function. Very handy in certain situations. This function could be used to load 10 different files with different callbacks all at the same time(depending on your level of csv love! )

I believe the id accessors don't match the bean naming conventions and that's why the exception is thrown. They should be as follows:

public Integer getId() { return id; }    
public void setId(Integer i){ id= i; }

border-radius:50% if you want the circle to adjust to whatever dimensions the container gets (e.g. if the text is variable length)

Don't forget the -moz- and -webkit- prefixes! (prefixing no longer needed)

div{
  border-radius: 50%;
  display: inline-block;
  background: lightgreen;
}

.a{
  padding: 50px;
}

.b{
  width: 100px;
  height: 100px;
}

<div class='a'></div>
<div class='b'></div>

Git just stores the contents of the link (i.e. the path of the file system object that it links to) in a 'blob' just like it would for a normal file. It then stores the name, mode and type (including the fact that it is a symlink) in the tree object that represents its containing directory.

When you checkout a tree containing the link, it restores the object as a symlink regardless of whether the target file system object exists or not.

If you delete the file that the symlink references it doesn't affect the Git-controlled symlink in any way. You will have a dangling reference. It is up to the user to either remove or change the link to point to something valid if needed.

string a = "10.65678";

decimal d = Math.Round(Convert.ToDouble(a.ToString()),2)

                .collect(Collectors.toList());
    }

Adding a bit to mitigate the confusion here. Even though Darren Davies' (accepted) answer is more straight forward, I think Andrei's answer is a better approach for MVC applications.

The answer from Andrei means that you can use HttpContext just as you would use System.Web.HttpContext.Current. For example, if you want to do this:

System.Web.HttpContext.Current.User.Identity.Name

you should instead do this:

HttpContext.User.Identity.Name

Both achieve the same result, but (again) in terms of MVC, the latter is more recommended.

Another good and also straight forward information regarding this matter can be found here: Difference between HttpContext.Current and Controller.Context in MVC ASP.NET.

Before you call an instance method or instance variable It needs a object(Instance). When instance variable is called from static method compiler doesn't know which is the object this variable belongs to. Because static methods doesn't have an object (Only one copy always). When you call an instance variable or instance methods from instance method it refer the this object. It means the variable belongs to whatever object created and each object have it's own copy of instance methods and variables.

Static variables are marked as static and instance variables doesn't have specific keyword.

Main point you are looking for is:

.tag-remove::before {
  content: 'x'; // here is your X(cross) sign.
  color: #fff;
  font-weight: 300;
  font-family: Arial, sans-serif;
}

FYI, you can make a close button by yourself very easily:

Often you have multiple input fields with a different length.

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    int allowedLength;
    switch(textField.tag) {
        case 1: 
            allowedLength = MAXLENGTHNAME;      // triggered for input fields with tag = 1
            break;
        case 2:
            allowedLength = MAXLENGTHADDRESS;   // triggered for input fields with tag = 2
            break;
        default:
            allowedLength = MAXLENGTHDEFAULT;   // length default when no tag (=0) value =255
            break;
    }

    if (textField.text.length >= allowedLength && range.length == 0) {
        return NO; // Change not allowed
    } else {
        return YES; // Change allowed
    }
}

Current page: It's possible to do even shorter. This single line sound more elegant to find the current page's file name:

var fileName = location.href.split("/").slice(-1); 

or...

var fileName = location.pathname.split("/").slice(-1)

This is cool to customize nav box's link, so the link toward the current is enlighten by a CSS class.

JS:

$('.menu a').each(function() {
    if ($(this).attr('href') == location.href.split("/").slice(-1)){ $(this).addClass('curent_page'); }
});

CSS:

a.current_page { font-size: 2em; color: red; }

You can get around this even more easily with the Rebase extension, just use hg pull --rebase and your commits are automatically re-comitted to the pulled revision, avoiding the branching issue.

Another solution that wasn't mentioned:

Example Here

var parent = document.querySelector('.parent');

if (parent.querySelector('.child') !== null) {
    // .. it's a child
}

It doesn't matter whether the element is a direct child, it will work at any depth.

Alternatively, using the .contains() method:

Example Here

var parent = document.querySelector('.parent'),
    child = document.querySelector('.child');

if (parent.contains(child)) {
    // .. it's a child
}

The other solutions have one of a few problems:

1. They don't preserve order, or
2. They don't remove a precise count of elements, e.g. for x = [1, 2, 2, 2] and y = [2, 2] they convert y to a set, and either remove all matching elements (leaving [1] only) or remove one of each unique element (leaving [1, 2, 2]), when the proper behavior would be to remove 2 twice, leaving [1, 2], or
3. They do O(m * n) work, where an optimal solution can do O(m + n) work

Alain was on the right track with Counter to solve #2 and #3, but that solution will lose ordering. The solution that preserves order (removing the first n copies of each value for n repetitions in the list of values to remove) is:

from collections import Counter

x = [1,2,3,4,3,2,1]  
y = [1,2,2]  
remaining = Counter(y)

out = []
for val in x:
    if remaining[val]:
        remaining[val] -= 1
    else:
        out.append(val)
# out is now [3, 4, 3, 1], having removed the first 1 and both 2s.

Try it online!

To make it remove the last copies of each element, just change the for loop to for val in reversed(x): and add out.reverse() immediately after exiting the for loop.

Constructing the Counter is O(n) in terms of y's length, iterating x is O(n) in terms of x's length, and Counter membership testing and mutation are O(1), while list.append is amortized O(1) (a given append can be O(n), but for many appends, the overall big-O averages O(1) since fewer and fewer of them require a reallocation), so the overall work done is O(m + n).

You can also test for to determine if there were any elements in y that were not removed from x by testing:

remaining = +remaining  # Removes all keys with zero counts from Counter
if remaining:
    # remaining contained elements with non-zero counts

In case someone would like to "add and commit" for a single file, which was my case, I created the script bellow to do just that:

#!/bin/bash

function usage {
    echo "Usage: $(basename $0) <filename> <commit_message>"    
}

function die {
    declare MSG="$@"
    echo -e "$0: Error: $MSG">&2
    exit 1
}

(( "$#" == 2 )) || die "Wrong arguments.\n\n$(usage)"

FILE=$1
COMMIT_MESSAGE=$2

[ -f $FILE ] || die "File $FILE does not exist"

echo -n adding $FILE to git...
git add $FILE || die "git add $FILE has failed."
echo done

echo "commiting $file to git..."
git commit -m "$COMMIT_MESSAGE" || die "git commit has failed."

exit 0

I named it "gitfile.sh" and added it to my $PATH. Then I can run git add and commit for a single file in one command:

gitfile.sh /path/to/file "MY COMMIT MESSAGE"

You can also use a formula in excel in order to convert this type of date to a date type excel can read: =DATEVALUE(CONCATENATE(MID(A1,8,3),MID(A1,4,4),RIGHT(A1,4)))

And you get: 12/7/2016 from: Wed Dec 07 00:00:00 UTC 2016

This is how you can do it. This code assumes the existance of a buffered image called 'image' (like your comment says)

// The required drawing location
int drawLocationX = 300;
int drawLocationY = 300;

// Rotation information

double rotationRequired = Math.toRadians (45);

This is strange but Logger.getLogger("global") does not work in my setup (as well as Logger.getLogger(Logger.GLOBAL_LOGGER_NAME)).

However Logger.getLogger("") does the job well.

Hope this info also helps somebody...

Honestly, much as I love sed for appropriate tasks, this is definitely a task for perl -- it's truly more powerful for this kind of one-liners, especially to "write it back to where it comes from" (perl's -i switch does it for you, and optionally also lets you keep the old version around e.g. with a .bak appended, just use -i.bak instead).

perl -i.bak -pe 's/\.jpg|\.png|\.gif/.jpg/

rather than intricate work in sed (if even possible there) or awk...

You can set the datagridview DataSource to null and rebind it again.

private void button1_Click(object sender, EventArgs e)
{
    myAccesscon.ConnectionString = connectionString;

    dataGridView.DataSource = null;
    dataGridView.Update();
    dataGridView.Refresh();
    OleDbCommand cmd = new OleDbCommand(sql, myAccesscon);
    myAccesscon.Open();
    cmd.CommandType = CommandType.Text;
    OleDbDataAdapter da = new OleDbDataAdapter(cmd);
    DataTable bookings = new DataTable();
    da.Fill(bookings);
    dataGridView.DataSource = bookings;
    myAccesscon.Close();
}

Answer for Python beginners

In simpler words:

1. The key= parameter of sort requires a key function (to be applied to be objects to be sorted) rather than a single key value and
2. that is just what operator.itemgetter(1) will give you: A function that grabs the first item from a list-like object.

(More precisely those are callables, not functions, but that is a difference that can often be ignored.)

Data view is good Feature of data table . We can filter the data table as per our requirements using data view . Below Functions is After binding data table to list box data source then filter by text box control . ( this condition you can change as per your needs .Contains(txtSearch.Text.Trim()) )

Private Sub BindClients()

   okcl = 0

    sql = "Select * from Client Order By cname"        
    Dim dacli As New SqlClient.SqlDataAdapter
    Dim cmd As New SqlClient.SqlCommand()
    cmd.CommandText = sql
    cmd.CommandType = CommandType.Text
    dacli.SelectCommand = cmd
    dacli.SelectCommand.Connection = Me.sqlcn
    Dim dtcli As New DataTable
    dacli.Fill(dtcli)
    dacli.Fill(dataTableClients)
    lstboxc.DataSource = dataTableClients
    lstboxc.DisplayMember = "cname"
    lstboxc.ValueMember = "ccode"
    okcl = 1

    If dtcli.Rows.Count > 0 Then
        ccode = dtcli.Rows(0)("ccode")
        Call ClientDispData1()
    End If
End Sub

Private Sub FilterClients()        

    Dim query As EnumerableRowCollection(Of DataRow) = From dataTableClients In 
    dataTableClients.AsEnumerable() Where dataTableClients.Field(Of String) 
    ("cname").Contains(txtSearch.Text.Trim()) Order By dataTableClients.Field(Of 
    String)("cname") Select dataTableClients

    Dim dataView As DataView = query.AsDataView()
    lstboxc.DataSource = dataView
    lstboxc.DisplayMember = "cname"
    lstboxc.ValueMember = "ccode"
    okcl = 1
    If dataTableClients.Rows.Count > 0 Then
        ccode = dataTableClients.Rows(0)("ccode")
        Call ClientDispData1()
    End If
End Sub

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

Mine is a bit more smaller and simpler:

/// <summary>
/// Runs a PowerShell script taking it's path and parameters.
/// </summary>
/// <param name="scriptFullPath">The full file path for the .ps1 file.</param>
/// <param name="parameters">The parameters for the script, can be null.</param>
/// <returns>The output from the PowerShell execution.</returns>
public static ICollection<PSObject> RunScript(string scriptFullPath, ICollection<CommandParameter> parameters = null)
{
    var runspace = RunspaceFactory.CreateRunspace();
    runspace.Open();
    var pipeline = runspace.CreatePipeline();
    var cmd = new Command(scriptFullPath);
    if (parameters != null)
    {
        foreach (var p in parameters)
        {
            cmd.Parameters.Add(p);
        }
    }
    pipeline.Commands.Add(cmd);
    var results = pipeline.Invoke();
    pipeline.Dispose();
    runspace.Dispose();
    return results;
}

Here's an example for those who have more complicated conditions and using Doctrine 2.* with QueryBuilder:

$qb->where('o.foo = 1')
   ->andWhere($qb->expr()->orX(
      $qb->expr()->eq('o.bar', 1),
      $qb->expr()->eq('o.bar', 2)
   ))
  ;

Those are expressions mentioned in Czechnology answer.

Select the text of all items under produce:

//produce/item/text()

Select all the manager nodes in all departments:

//department/*

By definition, by multiplying a 1D vector by its transpose, you've created a singular matrix.

Each row is a linear combination of the first row.

Notice that the second row is just 8x the first row.

Likewise, the third row is 50x the first row.

There's only one independent row in your matrix.

There is a difference between window.innerHeight and document.documentElement.clientHeight. The first includes the height of the horizontal scrollbar.

try $conn = mysql_connect("localhost", "root") or $conn = mysql_connect("localhost", "root", "")

You can run with:

java -cp .;app.jar package.MainClass

It works for me if there is no manifest in the JAR file.

A quick and copy/paste you can use for Chrome and Firefox would be: (change the stuff after the # to change the color)

-border-radius: 10px;
-moz-box-shadow: 0 0 15px 5px #666;
-webkit-box-shadow: 0 0 15px 05px #666;

Matt Roberts' answer is correct for webkit browsers (safari, chrome, etc), but I thought someone out there might want a quick answer rather than be told to learn to program to make some shadows.

foreach (var data in dynObj.quizlist)
{
    foreach (var data1 in data.QUIZ.QPROP)
    {
        Response.Write("Name" + ":" + data1.name + "<br>");
        Response.Write("Intro" + ":" + data1.intro + "<br>");
        Response.Write("Timeopen" + ":" + data1.timeopen + "<br>");
        Response.Write("Timeclose" + ":" + data1.timeclose + "<br>");
        Response.Write("Timelimit" + ":" + data1.timelimit + "<br>");
        Response.Write("Noofques" + ":" + data1.noofques + "<br>");

        foreach (var queprop in data1.QUESTION.QUEPROP)
        {
            Response.Write("Questiontext" + ":" + queprop.questiontext  + "<br>");
            Response.Write("Mark" + ":" + queprop.mark  + "<br>");
        }
    }
}

Yes Fiddler is an option for me:

1. Open Fiddler menu > Rules > Customize Rules (this effectively edits CustomRules.js).
2. Find the function OnBeforeResponse

3. Add the following lines:

   oSession.oResponse.headers.Remove("X-Frame-Options");
   oSession.oResponse.headers.Add("Access-Control-Allow-Origin", "*");
   

4. Remember to save the script!

How about this?

$( document ).ready(function() {
    $('#fixed').width($('#wrap').width());
});

By using jquery you can set any kind of width :)

EDIT: As stated by dream in the comments, using JQuery just for this effect is pointless and even counter productive. I made this example for people who use JQuery for other stuff on their pages and consider using it for this part also. I apologize for any inconvenience my answer caused.

It's actually much easier with jQuery's promise API:

$.ajax(
            type: "GET",
            url: requestURL,
        ).then((success) =>
            console.dir(success)
        ).failure((failureResponse) =>
            console.dir(failureResponse)
        )

Alternatively, you can pass in of bind functions to each result callback; the order of parameters is: (success, failure). So long as you specify a function with at least 1 parameter, you get access to the response. So, for example, if you wanted to check the response text, you could simply do:

$.ajax(
            type: "GET",
            url: @get("url") + "logout",
            beforeSend: (xhr) -> xhr.setRequestHeader("token", currentToken)
        ).failure((response) -> console.log "Request was unauthorized" if response.status is 401

To create an empty multidimensional array in NumPy (e.g. a 2D array m*n to store your matrix), in case you don't know m how many rows you will append and don't care about the computational cost Stephen Simmons mentioned (namely re-buildinging the array at each append), you can squeeze to 0 the dimension to which you want to append to: X = np.empty(shape=[0, n]).

This way you can use for example (here m = 5 which we assume we didn't know when creating the empty matrix, and n = 2):

import numpy as np

n = 2
X = np.empty(shape=[0, n])

for i in range(5):
    for j  in range(2):
        X = np.append(X, [[i, j]], axis=0)

print X

which will give you:

[[ 0.  0.]
 [ 0.  1.]
 [ 1.  0.]
 [ 1.  1.]
 [ 2.  0.]
 [ 2.  1.]
 [ 3.  0.]
 [ 3.  1.]
 [ 4.  0.]
 [ 4.  1.]]

I like this for log4j:

log4j.logger.org.hibernate.SQL=trace
log4j.logger.org.hibernate.engine.query=trace
log4j.logger.org.hibernate.type=trace
log4j.logger.org.hibernate.jdbc=trace
log4j.logger.org.hibernate.type.descriptor.sql.BasicExtractor=error 
log4j.logger.org.hibernate.type.CollectionType=error 

I needed to demo something quickly today and came up with this. Thought I would place it here if someone needed something similar to the OP's request.

#!/bin/bash

status_code=$(curl --write-out %{http_code} --silent --output /dev/null www.bbc.co.uk/news)

if [[ "$status_code" -ne 200 ]] ; then
  echo "Site status changed to $status_code" | mail -s "SITE STATUS CHECKER" "[email protected]" -r "STATUS_CHECKER"
else
  exit 0
fi

This will send an email alert on every state change from 200, so it's dumb and potentially greedy. To improve this, I would look at looping through several status codes and performing different actions dependant on the result.

I am a Windows and XAMPP user. What works for me is adding extension=php_pdo_mysql.dll in both php.ini of XAMPP and php.ini in C:\php\php.ini.

Run this command in your cmd to know where your config file is

php -i | find /i "Configuration File

use this command php artisan migrate --path=/database/migrations/my_migration.php it worked for me..

No fake inputs, no javascript!

There is no way to disable autofill consistently across browsers. I have tried all the different suggestions and none of them work in all browsers. The only way is not using password input at all. Here's what I came up with:

<style type="text/css">
    @font-face {
        font-family: 'PasswordDots';
        src: url('text-security-disc.woff') format('woff');
        font-weight: normal;
        font-style: normal;
    }

    input.password {
        font-family: 'PasswordDots' !important;
        font-size: 8px !important;
    }
</style>

<input class="password" type="text" spellcheck="false" />

Download: text-security-disc.woff

Here's how my final result looks like:

The negative side effect is that it's possible to copy plain text from the input, though it should be possible to prevent that with some JS.

The value 3172978990 is greater than 2147483647 – the maximum value for INT – hence the error. MySQL integer types and their ranges are listed here.

Also note that the (10) in INT(10) does not define the "size" of an integer. It specifies the display width of the column. This information is advisory only.

To fix the error, change your datatype to VARCHAR. Phone and Fax numbers should be stored as strings. See this discussion.

a.mean() takes an axis argument:

In [1]: import numpy as np

In [2]: a = np.array([[40, 10], [50, 11]])

In [3]: a.mean(axis=1)     # to take the mean of each row
Out[3]: array([ 25. ,  30.5])

In [4]: a.mean(axis=0)     # to take the mean of each col
Out[4]: array([ 45. ,  10.5])

Or, as a standalone function:

In [5]: np.mean(a, axis=1)
Out[5]: array([ 25. ,  30.5])

The reason your slicing wasn't working is because this is the syntax for slicing:

In [6]: a[:,0].mean() # first column
Out[6]: 45.0

In [7]: a[:,1].mean() # second column
Out[7]: 10.5

Your best solution is to look at the "opacity" tag of an element.

For example:

.image
{
    opacity:0.4;
    filter:alpha(opacity=40); /* For IE8 and earlier */
}

So in your case it should look something like :

<html><span style="opacity: 0.5;"><font color=\"black\" face=\"arial\" size=\"4\">THIS IS MY TEXT</font></html>

However don't forget the tag isn't supported in HTML5.

You should use a CSS too :)

I have also faced the same type of problem when I had to parse a CSV file.

The file contains a column address which contains the ',' .

After parsing that CSV file to JSON, I get mismatched mapping of the keys while converting it into a JSON file.

I used Node.js for parsing the file and libraries like baby parse and csvtojson.

Example of file -

address,pincode
foo,baar , 123456

While I was parsing directly without using baby parse in JSON, I was getting:

[{
 address: 'foo',
 pincode: 'baar',
 'field3': '123456'
}]

So I wrote code which removes the comma(,) with any other delimiter with every field:

/*
 csvString(input) = "address, pincode\\nfoo, bar, 123456\\n"
 output = "address, pincode\\nfoo {YOUR DELIMITER} bar, 123455\\n"
*/
const removeComma = function(csvString){
    let delimiter = '|'
    let Baby = require('babyparse')
    let arrRow = Baby.parse(csvString).data;
    /*
      arrRow = [
      [ 'address', 'pincode' ],
      [ 'foo, bar', '123456']
      ]
    */
    return arrRow.map((singleRow, index) => {
        //the data will include
        /*
        singleRow = [ 'address', 'pincode' ]
        */
        return singleRow.map(singleField => {
            //for removing the comma in the feild
            return singleField.split(',').join(delimiter)
        })
    }).reduce((acc, value, key) => {
        acc = acc +(Array.isArray(value) ?
         value.reduce((acc1, val)=> {
            acc1 = acc1+ val + ','
            return acc1
        }, '') : '') + '\n';
        return acc;
    },'')
}

The function returned can be passed into the csvtojson library and thus the result can be used.

const csv = require('csvtojson')

let csvString = "address, pincode\\nfoo, bar, 123456\\n"
let jsonArray = []
modifiedCsvString = removeComma(csvString)
csv()
  .fromString(modifiedCsvString)
  .on('json', json => jsonArray.push(json))
  .on('end', () => {
    /* do any thing with the json Array */
  })

Now you can get the output like:

[{
  address: 'foo, bar',
  pincode: 123456
}]

Code should be written to be understandable to the programmer first, and the compiler or interpreter second. The "is not" construct resembles English more closely than "not is".

Another important module that needs reconfiguring before PUT and DELETE will work is the options verb

<modules>
<remove name="WebDAVModule" />
</modules>
<handlers>
<remove name="OPTIONSVerbHandler" />
<remove name="WebDAV" />
<add name="OPTIONSVerbHandler" path="*" verb="*" modules="ProtocolSupportModule" resourceType="Unspecified" requireAccess="Script" />
</handlers>

Also see this post: https://stackoverflow.com/a/22018750/9376681

Looking around, and using some C# 3.0 features we can do this:

foreach (KeyValuePair<string,int> item in keywordCounts.OrderBy(key=> key.Value))
{ 
    // do something with item.Key and item.Value
}

This is the cleanest way I've seen and is similar to the Ruby way of handling hashes.

The CSS content property along with ::after and ::before pseudo-elements have been introduced for this.

.item:hover a p.new-label:after{
    content: 'ADD';
}

JSFiddle Demo

When the toastr message poped up on the screen of firefox. the below tag was displayed in fire bug.

<div class="toast-message">Invalid Credentials, Please check Password</div>.

I took the screenshot at that time. And did the below changes in selenium java code.

String alertText = "";
WebDriverWait wait = new WebDriverWait(driver, 5);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("toast-message")));
WebElement toast1 = driver.findElement(By.className("toast-message"));  
alertText = toast1.getText();
System.out.println( alertText);

And my issue of toastr popup got resolved.

Internally in SQL Server dates are stored as 2 integers. The first integer is the number of dates before or after the base date (1900/01/01). The second integer stores the number of clock ticks after midnight, each tick is 1/300 of a second.

More info here

Because of this, I often find the simplest way to compare dates is to simply substract them. This handles 90% of my use cases. E.g.,

select date1, date2, date2 - date1 as DifferenceInDays
from MyTable
...

When I need an answer in units other than days, I will use DateDiff.

Why don't you just use a singleton?

import android.content.Context;


public class ClassicSingleton {
    private Context c=null;
    private static ClassicSingleton instance = null;
    protected ClassicSingleton()
    {
       // Exists only to defeat instantiation.
    }
    public void setContext(Context ctx)
    {
    c=ctx;
    }
    public Context getContext()
    {
       return c;
    }
    public static ClassicSingleton getInstance()
    {
        if(instance == null) {
            instance = new ClassicSingleton();
        }
        return instance;
    }
}

Then in the activity class:

 private ClassicSingleton cs = ClassicSingleton.getInstance();

And in the non activity class:

ClassicSingleton cs= ClassicSingleton.getInstance();
        Context c=cs.getContext();
        ImageView imageView = (ImageView) ((Activity)c).findViewById(R.id.imageView1);

Slickedit and Notepad2 also show them. In Slickedit you can customize all sorts of invisible characters (whitespace, tabs, CRs, line feeds, ...) and display them with any character you wish.

This is an direct excerpt from the excellent book 'Thinking in Java' by Bruce Eckel.

[..] Should you use an interface or an abstract class?

Well, an interface gives you the benefits of an abstract class and the benefits of an interface, so if it’s possible to create your base class without any method definitions or member variables you should always prefer interfaces to abstract classes.

In fact, if you know something is going to be a base class, your first choice should be to make it an interface, and only if you’re forced to have method definitions or member variables should you change to an abstract class.

Isn't this the normal way to free the memory associated with an object?

This is a common way of managing dynamically allocated memory, but it's not a good way to do so. This sort of code is brittle because it is not exception-safe: if an exception is thrown between when you create the object and when you delete it, you will leak that object.

It is far better to use a smart pointer container, which you can use to get scope-bound resource management (it's more commonly called resource acquisition is initialization, or RAII).

As an example of automatic resource management:

void test()
{
    std::auto_ptr<Object1> obj1(new Object1);

} // The object is automatically deleted when the scope ends.

Depending on your use case, auto_ptr might not provide the semantics you need. In that case, you can consider using shared_ptr.

As for why your program crashes when you delete the object, you have not given sufficient code for anyone to be able to answer that question with any certainty.

You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Traditional approach

In the traditional approach you return Observable<HttpResponse<T>> from Service API. This is tied to HttpResponse.

With this approach you have to use .subscribe(x => ...) in the rest of your code.

This creates a tight coupling between the http layer and the rest of your code.

Strongly-typed callback approach

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

export class SearchModel {
    code: string;
}

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.post<SearchModel, RacingResponse>(url, model, 
                                                      ResponseType.IObservable, success, 
                                                      ErrorType.IObservableError, failure);

Your Component

In your Component, your Service is injected and the searchRaceInfo API called as shown below.

  search() {    


    this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
                                                  error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

Maybe you should take a look here: http://en.wikipedia.org/wiki/Luhn_algorithm

Here is Java snippet which validates a credit card number which should be easy enough to convert to JavaScript:

  public static boolean isValidCC(String number) {

    final int[][] sumTable = {{0,1,2,3,4,5,6,7,8,9},{0,2,4,6,8,1,3,5,7,9}};
    int sum = 0, flip = 0;

    for (int i = number.length() - 1; i >= 0; i--) {
      sum += sumTable[flip++ & 0x1][Character.digit(number.charAt(i), 10)];
    }
    return sum % 10 == 0;
  }

I encountered this problem while upgrading from CXF 2.7.0 to 3.0.2. Here is what I did to resolve it:

Included the following in my pom.xml

    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-rs-extension-providers</artifactId>
        <version>3.0.2</version>
    </dependency>

    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-jaxrs</artifactId>
        <version>1.9.0</version>
    </dependency>

and added the following provider

    <jaxrs:providers>
        <bean class="org.codehaus.jackson.jaxrs.JacksonJaxbJsonProvider" />
    </jaxrs:providers>

We can sort() function to sort string array.

Procedure :

1. At first determine the size string array.

2. use sort function . sort(array_name, array_name+size)

3. Iterate through string array/

Code Snippet

#include<bits/stdc++.h>
using namespace std;

int main()
{
    ios::sync_with_stdio(false);

    string name[] = {"john", "bobby", "dear", "test1", "catherine", "nomi", "shinta", "martin", "abe", "may", "zeno", "zack", "angeal", "gabby"};

    int len = sizeof(name)/sizeof(name[0]);

    sort(name, name+len);

    for(string n: name)
    {
         cout<<n<<" ";
    }
    cout<<endl;

    return 0;
}

I would like this

from subprocess import call

command = "youtube-dl https://www.youtube.com/watch?v=NG3WygJmiVs -c"
call(command.split(), shell=False)

If you want to make sure that last row does not wrap and thus size the way you want it, have a look at

td {
 white-space: nowrap;
}

You don't need jQuery. You can do this using a for loop:

var total = 0;
for (var i = 0; i < someArray.length; i++) {
    total += someArray[i] << 0;
}

I believe your question is to change only width of view dynamically, whereas above methods will change layout properties completely to new one, so I suggest to getLayoutParams() from view first, then set width on layoutParams, and finally set layoutParams to the view, so following below steps to do the same.

View view = findViewById(R.id.nutrition_bar_filled);
LayoutParams layoutParams = view.getLayoutParams();
layoutParams.width = newWidth;
view.setLayoutParams(layoutParams);

I thought by setting the first element to a null would clear the entire contents of a char array.

That is not correct as you discovered

However, this only sets the first element to null.

Exactly!

You need to use memset to clear all the data, it is not sufficient to set one of the entries to null.

However, if setting an element of the array to null means something special (for example when using a null terminating string in) it might be sufficient to set the first element to null. That way any user of the array will understand that it is empty even though the array still includes the old chars in memory

While jball's answer is an excellent description of content insets, it doesn't answer the question of when to use it. I'll borrow from his diagrams:

  _|?_cW_?_|_?_
   |       | 
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
   |content|    
-------------?-

That's what you get when you do it, but the usefulness of it only shows when you scroll:

  _|?_cW_?_|_?_
   |content| ? content is still visible
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
  _|_______|___ 
             ?

That top row of content will still be visible because it's still inside the frame of the scroll view. One way to think of the top offset is "how much to shift the content down the scroll view when we're scrolled all the way to the top"

To see a place where this is actually used, look at the build-in Photos app on the iphone. The Navigation bar and status bar are transparent, and the contents of the scroll view are visible underneath. That's because the scroll view's frame extends out that far. But if it wasn't for the content inset, you would never be able to have the top of the content clear that transparent navigation bar when you go all the way to the top.

You can use list comprehension on a dataframe to count frequencies of the columns as such

[my_series[c].value_counts() for c in list(my_series.select_dtypes(include=['O']).columns)]

Breakdown:

my_series.select_dtypes(include=['O']) 

Selects just the categorical data

list(my_series.select_dtypes(include=['O']).columns) 

Turns the columns from above into a list

[my_series[c].value_counts() for c in list(my_series.select_dtypes(include=['O']).columns)] 

Iterates through the list above and applies value_counts() to each of the columns

Regarding the differences between json and jsonb datatypes, it worth mentioning the official explanation:

PostgreSQL offers two types for storing JSON data: json and jsonb. To implement efficient query mechanisms for these data types, PostgreSQL also provides the jsonpath data type described in Section 8.14.6.

The json and jsonb data types accept almost identical sets of values as input. The major practical difference is one of efficiency. The json data type stores an exact copy of the input text, which processing functions must reparse on each execution; while jsonb data is stored in a decomposed binary format that makes it slightly slower to input due to added conversion overhead, but significantly faster to process, since no reparsing is needed. jsonb also supports indexing, which can be a significant advantage.

Because the json type stores an exact copy of the input text, it will preserve semantically-insignificant white space between tokens, as well as the order of keys within JSON objects. Also, if a JSON object within the value contains the same key more than once, all the key/value pairs are kept. (The processing functions consider the last value as the operative one.) By contrast, jsonb does not preserve white space, does not preserve the order of object keys, and does not keep duplicate object keys. If duplicate keys are specified in the input, only the last value is kept.

In general, most applications should prefer to store JSON data as jsonb, unless there are quite specialized needs, such as legacy assumptions about ordering of object keys.

PostgreSQL allows only one character set encoding per database. It is therefore not possible for the JSON types to conform rigidly to the JSON specification unless the database encoding is UTF8. Attempts to directly include characters that cannot be represented in the database encoding will fail; conversely, characters that can be represented in the database encoding but not in UTF8 will be allowed.

Just a little addition. If you've only selected 1 row then the code below will select the value of a column (index of 4, but 5th column) for the selected row:

me.lstIssues.Column(4)

This saves having to use the ItemsSelected property.

The syntax for using an alias in an update statement on SQL Server is as follows:

UPDATE Q
SET Q.TITLE = 'TEST'
FROM HOLD_TABLE Q
WHERE Q.ID = 101;

The alias should not be necessary here though.

• The continue statement looks wrong.

• You want to start at 2 because 2 is the first prime number.

• You can write "while True:" to get an infinite loop.

You can change the user with

• Subversion 1.6 and earlier:

  svn switch --relocate protocol://currentUser@server/path protocol://newUser@server/path
  

• Subversion 1.7 and later:

  svn relocate protocol://currentUser@server/path protocol://newUser@server/path
  

To find out what protocol://currentUser@server/path is, run

svn info

in your working copy.

I hope this is helpful to you.

Please try this code,

 @Html.DropDownListFor(model => model.Items, new List<SelectListItem>
   { new SelectListItem{Text="Deactive", Value="False"},
     new SelectListItem{Text="Active", Value="True",  Selected = true},
     })

I was having issues getting this working (on OSX). I'd followed the instructions provided by Postman, and the advice here, and cookies were still not being set.

However, the post above saying "So if you enable interceptor only in browser - it will not work" alerted me to the fact that the interceptor could be enabled in the browser as well as in Postman itself. I thought I'd try switching it on in the browser, to see if that helped, and it did. I then switched it off in the browser, and it still worked.

So, if you are having issues getting it working, I'd suggest trying switching it on in browser at least once, as, for me, this seemed to trigger it into life. I think you will still need it switch on in Postman too.

new_data <- data %>% filter_all(any_vars(is.na(.))) 

This should create a new data frame (new_data) with only the missing values in it.

Works best to keep a track of values that you might later drop because they had some columns with missing observations (NA).

If you are using PHP you can use this, and I'm sure it's almost similar in other languages as well

$WebsiteURL = "https://api.telegram.org/bot".$BotToken;
$text = "<b>This</b> <i>is some Text</i>";
$Update = file_get_contents($WebsiteURL."/sendMessage?chat_id=$chat_id&text=$text&parse_mode=html);

echo $Update;

Here is the list of all tags that you can use

<b>bold</b>, <strong>bold</strong>
<i>italic</i>, <em>italic</em>
<a href="http://www.example.com/">inline URL</a>
<code>inline fixed-width code</code>
<pre>pre-formatted fixed-width code block</pre>

Define a module ( call it "globalbaz" ) and have the variables defined inside it. All the modules using this "pseudoglobal" should import the "globalbaz" module, and refer to it using "globalbaz.var_name"

This works regardless of the place of the change, you can change the variable before or after the import. The imported module will use the latest value. (I tested this in a toy example)

For clarification, globalbaz.py looks just like this:

var_name = "my_useful_string"

Can the screenshot or icon be transformed (scaled, rotated, skewed ...)? There are quite a few methods on top of my head that could possibly help you:

• Simple euclidean distance as mentioned by @carlosdc (doesn't work with transformed images and you need a threshold).
• (Normalized) Cross Correlation - a simple metrics which you can use for comparison of image areas. It's more robust than the simple euclidean distance but doesn't work on transformed images and you will again need a threshold.
• Histogram comparison - if you use normalized histograms, this method works well and is not affected by affine transforms. The problem is determining the correct threshold. It is also very sensitive to color changes (brightness, contrast etc.). You can combine it with the previous two.
• Detectors of salient points/areas - such as MSER (Maximally Stable Extremal Regions), SURF or SIFT. These are very robust algorithms and they might be too complicated for your simple task. Good thing is that you do not have to have an exact area with only one icon, these detectors are powerful enough to find the right match. A nice evaluation of these methods is in this paper: Local invariant feature detectors: a survey.

Most of these are already implemented in OpenCV - see for example the cvMatchTemplate method (uses histogram matching): http://dasl.mem.drexel.edu/~noahKuntz/openCVTut6.html. The salient point/area detectors are also available - see OpenCV Feature Detection.

How is this usually done? Should I copy the cmake/ directory of SomeLib into my project and set the CMAKE_MODULE_PATH relatively?

If you don't trust CMake to have that module, then - yes, do that - sort of: Copy the find_SomeLib.cmake and its dependencies into your cmake/ directory. That's what I do as a fallback. It's an ugly solution though.

Note that the FindFoo.cmake modules are each a sort of a bridge between platform-dependence and platform-independence - they look in various platform-specific places to obtain paths in variables whose names is platform-independent.

You could wrap your array as a list, and request a sublist of it.

MyClass[] array = ...;
List<MyClass> subArray = Arrays.asList(array).subList(index, array.length);

You should use the print() function which is available since Python 2.6+

from __future__ import print_function  # Only needed for Python 2
print("hi there", file=f)

For Python 3 you don't need the import, since the print() function is the default.

The alternative would be to use:

f = open('myfile', 'w')
f.write('hi there\n')  # python will convert \n to os.linesep
f.close()  # you can omit in most cases as the destructor will call it

Quoting from Python documentation regarding newlines:

On output, if newline is None, any '\n' characters written are translated to the system default line separator, os.linesep. If newline is '', no translation takes place. If newline is any of the other legal values, any '\n' characters written are translated to the given string.

I want to be able to create a variable name containing the first argument of the command

script.sh file:

#!/usr/bin/env bash
function grep_search() {
  eval $1=$(ls | tail -1)
}

Test:

$ source script.sh
$ grep_search open_box
$ echo $open_box
script.sh

As per help eval:

Execute arguments as a shell command.

You may also use Bash ${!var} indirect expansion, as already mentioned, however it doesn't support retrieving of array indices.

For further read or examples, check BashFAQ/006 about Indirection.

We are not aware of any trick that can duplicate that functionality in POSIX or Bourne shells without eval, which can be difficult to do securely. So, consider this a use at your own risk hack.

However, you should re-consider using indirection as per the following notes.

Normally, in bash scripting, you won't need indirect references at all. Generally, people look at this for a solution when they don't understand or know about Bash Arrays or haven't fully considered other Bash features such as functions.

Putting variable names or any other bash syntax inside parameters is frequently done incorrectly and in inappropriate situations to solve problems that have better solutions. It violates the separation between code and data, and as such puts you on a slippery slope toward bugs and security issues. Indirection can make your code less transparent and harder to follow.

(n,) and (n,1) are not the same shape. Try casting the vector to an array by using the [:, None] notation:

n_lists = np.append(n_list_converted, n_last[:, None], axis=1)

Alternatively, when extracting n_last you can use

n_last = n_list_converted[:, -1:]

to get a (20, 1) array.

Both pandas and matplotlib.dates use matplotlib.units for locating the ticks.

But while matplotlib.dates has convenient ways to set the ticks manually, pandas seems to have the focus on auto formatting so far (you can have a look at the code for date conversion and formatting in pandas).

So for the moment it seems more reasonable to use matplotlib.dates (as mentioned by @BrenBarn in his comment).

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt 
import matplotlib.dates as dates

idx = pd.date_range('2011-05-01', '2011-07-01')
s = pd.Series(np.random.randn(len(idx)), index=idx)

fig, ax = plt.subplots()
ax.plot_date(idx.to_pydatetime(), s, 'v-')
ax.xaxis.set_minor_locator(dates.WeekdayLocator(byweekday=(1),
                                                interval=1))
ax.xaxis.set_minor_formatter(dates.DateFormatter('%d\n%a'))
ax.xaxis.grid(True, which="minor")
ax.yaxis.grid()
ax.xaxis.set_major_locator(dates.MonthLocator())
ax.xaxis.set_major_formatter(dates.DateFormatter('\n\n\n%b\n%Y'))
plt.tight_layout()
plt.show()

With bs4 4.7.1+ you can use :contains pseudo class to specify the td containing your search string

from bs4 import BeautifulSoup
html = '''
<tr>
  <td class="pos">\n
      "Some text:"\n
      <br>\n
      <strong>some value</strong>\n
  </td>
</tr>
<tr>
  <td class="pos">\n
      "Fixed text:"\n
      <br>\n
      <strong>text I am looking for</strong>\n
  </td>
</tr>
<tr>
  <td class="pos">\n
      "Some other text:"\n
      <br>\n
      <strong>some other value</strong>\n
  </td>
</tr>'''
soup = bs(html, 'lxml')
print(soup.select_one('td:contains("Fixed text:")'))

The following code the easiest way:

 <h:outputLabel value="value = 10" rendered="#{row == 10}" /> 
 <h:outputLabel value="value = 15" rendered="#{row == 15}" /> 
 <h:outputLabel value="value xyz" rendered="#{row != 15 and row != 10}" />
