Small addition to all of above:

Better use map, when you need to get elements by range, as they are sorted and you can just iterate over them from one boundary to another.

I think, jogojapan gave an very good and exhaustive answer. You definitively should take a look at it before reading my post. However, I'd like to add the following:

1. You can define a comparison function for an unordered_map separately, instead of using the equality comparison operator (operator==). This might be helpful, for example, if you want to use the latter for comparing all members of two Node objects to each other, but only some specific members as key of an unordered_map.
2. You can also use lambda expressions instead of defining the hash and comparison functions.

All in all, for your Node class, the code could be written as follows:

using h = std::hash<int>;
auto hash = [](const Node& n){return ((17 * 31 + h()(n.a)) * 31 + h()(n.b)) * 31 + h()(n.c);};
auto equal = [](const Node& l, const Node& r){return l.a == r.a && l.b == r.b && l.c == r.c;};
std::unordered_map<Node, int, decltype(hash), decltype(equal)> m(8, hash, equal);

Notes:

• I just reused the hashing method at the end of jogojapan's answer, but you can find the idea for a more general solution here (if you don't want to use Boost).
• My code is maybe a bit too minified. For a slightly more readable version, please see this code on Ideone.

I don't know if my solution is best practice, but I achieved loading a bitmap with my desired scaling by using the inDensity and inTargetDensity options. inDensity is 0 initially when not loading a drawable resource, so this approach is for loading non resource images.

The variables imageUri, maxImageSideLength and context are parameters of my method. I posted only the method implementation without the wrapping AsyncTask for clarity.

            ContentResolver resolver = context.getContentResolver();
            InputStream is;
            try {
                is = resolver.openInputStream(imageUri);
            } catch (FileNotFoundException e) {
                Log.e(TAG, "Image not found.", e);
                return null;
            }
            Options opts = new Options();
            opts.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(is, null, opts);

            // scale the image
            float maxSideLength = maxImageSideLength;
            float scaleFactor = Math.min(maxSideLength / opts.outWidth, maxSideLength / opts.outHeight);
            // do not upscale!
            if (scaleFactor < 1) {
                opts.inDensity = 10000;
                opts.inTargetDensity = (int) ((float) opts.inDensity * scaleFactor);
            }
            opts.inJustDecodeBounds = false;

            try {
                is.close();
            } catch (IOException e) {
                // ignore
            }
            try {
                is = resolver.openInputStream(imageUri);
            } catch (FileNotFoundException e) {
                Log.e(TAG, "Image not found.", e);
                return null;
            }
            Bitmap bitmap = BitmapFactory.decodeStream(is, null, opts);
            try {
                is.close();
            } catch (IOException e) {
                // ignore
            }

            return bitmap;

Parameters are key-value pairs that can appear inside URL path, and start with a semicolon character (;).

Query string appears after the path (if any) and starts with a question mark character (?).

Both parameters and query string contain key-value pairs.

In a GET request, parameters appear in the URL itself:

<scheme>://<username>:<password>@<host>:<port>/<path>;<parameters>?<query>#<fragment>

In a POST request, parameters can appear in the URL itself, but also in the datastream (as known as content).

Query string is always a part of the URL.

Parameters can be buried in form-data datastream when using POST method so they may not appear in the URL. Yes a POST request can define parameters as form data and in the URL, and this is not inconsistent because parameters can have several values.

I've found no explaination for this behavior so far. I guess it might be useful sometimes to "unhide" parameters from a POST request, or even let the code handling a GET request share some parts with the code handling a POST. Of course this can work only with server code supporting parameters in a URL.

Until you get better insights, I suggest you to use parameters only in form-data datastream of POST requests.

Working example: http://jsfiddle.net/QtftX/1/

to answer to : int a = (b == 5) ? c : d;

just write:

b=5
c=1
d=2
let a="(b==5)?c:d"

echo $a # 1

b=6;
c=1;
d=2;
let a="(b==5)?c:d"

echo $a # 2

remember that " expression " is equivalent to $(( expression ))

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

Check on yourCheckBox.Value ?

Enough already is said on this topic by good folks here. But here is my 2 cents.

There are 2 modes of interaction:

1. human-to-machine (HTM)
2. machine-to-machine (MTM)

The machine is the common denominator, expressed as the REST APIs, and the actors/clients being either the humans or the machines.

Now, in a truly RESTful architecture, the concept of statelessness implies that all relevant application states (meaning the client side states) must be supplied with each and every request. By relevant, it is meant that whatever is required by the REST API to process the request and serve an appropriate response.

When we consider this in the context of human-to-machine applications, "browser-based" as Skrebbel points out above, this means that the (web) application running in the browser will need to send its state and relevant information with each request it makes to the back end REST APIs.

Consider this: You have a data/information platform exposed asset of REST APIs. Perhaps you have a self-service BI platform that handles all the data cubes. But you want your (human) customers to access this via (1) web app, (2) mobile app, and (3) some 3rd party application. In the end, even chain of MTMs leads up to HTM - right. So human users remain at the apex of information chain.

In the first 2 cases, you have a case for human-to-machine interaction, the information being actually consumed by a human user. In the last case, you have a machine program consuming the REST APIs.

The concept of authentication applies across the board. How will you design this so that your REST APIs are accessed in a uniform, secured manner? The way I see this, there are 2 ways:

Way-1:

1. There is no login, to begin with. Every request performs the login
2. The client sends its identifying parameters + the request specific parameters with each request
3. The REST API takes them, turns around, pings the user store (whatever that is) and confirms the auth
4. If the auth is established, services the request; otherwise, denies with appropriate HTTP status code
5. Repeat the above for every request across all the REST APIs in your catalog

Way-2:

1. The client begins with an auth request
2. A login REST API will handle all such requests
3. It takes in auth parameters (API key, uid/pwd or whatever you choose) and verifies auth against the user store (LDAP, AD, or MySQL DB etc.)
4. If verified, creates an auth token and hands it back to the client/caller
5. The caller then sends this auth token + request specific params with every subsequent request to other business REST APIs, until logged out or until the lease expires

Clearly, in Way-2, the REST APIs will need a way to recognize and trust the token as valid. The Login API performed the auth verification, and therefore that "valet key" needs to be trusted by other REST APIs in your catalog.

This, of course, means that the auth key/token will need to be stored and shared among the REST APIs. This shared, trusted token repository can be local/federated whatever, allowing REST APIs from other organizations to trust each other.

But I digress.

The point is, a "state" (about the client's authenticated status) needs to be maintained and shared so that all REST APIs can create a circle of trust. If we do not do this, which is the Way-1, we must accept that an act of authentication must be performed for any/all requests coming in.

Performing authentication is a resource-intensive process. Imagine executing SQL queries, for every incoming request, against your user store to check for uid/pwd match. Or, to encrypt and perform hash matches (the AWS style). And architecturally, every REST API will need to perform this, I suspect, using a common back-end login service. Because, if you don't, then you litter the auth code everywhere. A big mess.

So more the layers, more latency.

Now, take Way-1 and apply to HTM. Does your (human) user really care if you have to send uid/pwd/hash or whatever with every request? No, as long as you don't bother her by throwing the auth/login page every second. Good luck having customers if you do. So, what you will do is to store the login information somewhere on the client side, in the browser, right at the beginning, and send it with every request made. For the (human) user, she has already logged in, and a "session" is available. But in reality, she is authenticated on every request.

Same with Way-2. Your (human) user will never notice. So no harm was done.

What if we apply Way-1 to MTM? In this case, since its a machine, we can bore the hell out of this guy by asking it submit authentication information with every request. Nobody cares! Performing Way-2 on MTM will not evoke any special reaction; its a damn machine. It could care less!

So really, the question is what suits your need. Statelessness has a price to pay. Pay the price and move on. If you want to be a purist, then pay the price for that too, and move on.

In the end, philosophies do not matter. What really matters is information discovery, presentation, and the consumption experience. If people love your APIs, you did your job.

Entity-Framework Select Distinct Name:

Suppose if you are using Views in which you are using multiple tables and you want to apply distinct in that case first you have to store value in variable & then you can apply Distinct on that variable like this one....

public List<Item_Img_Sal_VIEW> GetItemDescription(int ItemNo) 
        {
            var Result= db.Item_Img_Sal_VIEW.Where(p => p.ItemID == ItemNo).ToList();
            return Result.Distinct().ToList();
        }

Or you can try this Simple Example

Public Function GetUniqueLocation() As List(Of Integer)
          Return db.LoginUsers.Select(Function(p) p.LocID).Distinct().ToList()
End Function

There are many ways to do this. My favorite way is:

1. Add a mod_user field to your source table (the one you want to log).

2. Create a log table that contains the fields you want to log, plus a log_datetime and seq_num field. seq_num is the primary key.

3. Build a trigger on the source table that inserts the current record into the log table whenever any monitored field is changed.

Now you've got a record of every change and who made it.

What I have done was to use: html_entity_decode, then use strip_tags to removed them.

You could output them to a .csv file and open the file in excel. Is that direct enough?

I had an error in my XML layout. So check your xml layout for errors.

Delete the line /*# sourceMappingURL=bootstrap.css.map */ from bootstrap.css

var model = JSON.stringify({ 
    'ID': 0, 
    'ProductID': $('#ID').val(), 
    'PartNumber': $('#part-number').val(),
    'VendorID': $('#Vendors').val()
})

$.ajax({
    type: "POST",
    dataType: "json",
    contentType: "application/json",
    url: "/api/PartSourceAPI/",
    data: model,
    success: function (data) {
        alert('success');
    },
    error: function (error) {
        jsonValue = jQuery.parseJSON(error.responseText);
        jError('An error has occurred while saving the new part source: ' + jsonValue, { TimeShown: 3000 });
    }
});

var model = JSON.stringify({      'ID': 0,     ...': 5,      'PartNumber': 6,     'VendorID': 7 }) // output is "{"ID":0,"ProductID":5,"PartNumber":6,"VendorID":7}"

your data is something like this "{"model": "ID":0,"ProductID":6,"PartNumber":7,"VendorID":8}}" web api controller cannot bind it to Your model

This is another solution with lambda:

#include <cmath>
#include <limits>

auto Compare = [](float a, float b, float epsilon = std::numeric_limits<float>::epsilon()){ return (std::fabs(a - b) <= epsilon); };

pyinstaller --clean --onefile --icon=default.ico Registry.py

It works for Me

select count(*) from YourTable

Sooner or later you will have property with special character. You can either use index or combination of index and property.

dynamic jsonObject = new JObject();
jsonObject["Create-Date"] = DateTime.Now; //<-Index use
jsonObject.Album = "Me Against the world"; //<- Property use
jsonObject["Create-Year"] = 1995; //<-Index use
jsonObject.Artist = "2Pac"; //<-Property use

Try this first:

git checkout master

(If you're on a different branch than master, use the branch name there instead.)

If that doesn't work, try...

For a single file:

git checkout HEAD /path/to/file

For the entire repository working copy:

git reset --hard HEAD

And if that doesn't work, then you can look in the reflog to find your old head SHA and reset to that:

git reflog
git reset --hard <sha from reflog>

HEAD is a name that always points to the latest commit in your current branch.

With LINQ:

List<string> l = new List<string> { "1", "2", "3" ,"4","5"};
List<string> l2 = l.Skip(1).Take(2).ToList();

If you need foreach, then no need for ToList:

foreach (string s in l.Skip(1).Take(2)){}

Advantage of LINQ is that if you want to just skip some leading element,you can :

List<string> l2 = l.Skip(1).ToList();
foreach (string s in l.Skip(1)){}

i.e. no need to take care of count/length, etc.

Is there any particular reason that you need to use find? You can just use ls to find files that match a pattern in a directory.

ls /dev/abc-*

If you do need to use find, you can use the -maxdepth 1 switch to only apply to the specified directory.

Whenever you don't have access to documentation (SVNBook), type (Linux):

svn help status | grep \'\?\'
svn help status | grep \'\!\'
svn help status | grep \'\YOUR_SYMBOL_HERE\'

or insert the following function in your ~/.bashrc file, like so:

svncode() {
  symbol=$1
  [ $symbol ] &&  svn help status | grep \'$(echo $symbol)\' || \
  echo "usage: svncode <symbol>"
}

The best way of appending a string to a string variable is to use + or +=. This is because it's readable and fast. They are also just as fast, which one you choose is a matter of taste, the latter one is the most common. Here are timings with the timeit module:

a = a + b:
0.11338996887207031
a += b:
0.11040496826171875

However, those who recommend having lists and appending to them and then joining those lists, do so because appending a string to a list is presumably very fast compared to extending a string. And this can be true, in some cases. Here, for example, is one million appends of a one-character string, first to a string, then to a list:

a += b:
0.10780501365661621
a.append(b):
0.1123361587524414

OK, turns out that even when the resulting string is a million characters long, appending was still faster.

Now let's try with appending a thousand character long string a hundred thousand times:

a += b:
0.41823482513427734
a.append(b):
0.010656118392944336

The end string, therefore, ends up being about 100MB long. That was pretty slow, appending to a list was much faster. That that timing doesn't include the final a.join(). So how long would that take?

a.join(a):
0.43739795684814453

Oups. Turns out even in this case, append/join is slower.

So where does this recommendation come from? Python 2?

a += b:
0.165287017822
a.append(b):
0.0132720470428
a.join(a):
0.114929914474

Well, append/join is marginally faster there if you are using extremely long strings (which you usually aren't, what would you have a string that's 100MB in memory?)

But the real clincher is Python 2.3. Where I won't even show you the timings, because it's so slow that it hasn't finished yet. These tests suddenly take minutes. Except for the append/join, which is just as fast as under later Pythons.

Yup. String concatenation was very slow in Python back in the stone age. But on 2.4 it isn't anymore (or at least Python 2.4.7), so the recommendation to use append/join became outdated in 2008, when Python 2.3 stopped being updated, and you should have stopped using it. :-)

(Update: Turns out when I did the testing more carefully that using + and += is faster for two strings on Python 2.3 as well. The recommendation to use ''.join() must be a misunderstanding)

However, this is CPython. Other implementations may have other concerns. And this is just yet another reason why premature optimization is the root of all evil. Don't use a technique that's supposed "faster" unless you first measure it.

Therefore the "best" version to do string concatenation is to use + or +=. And if that turns out to be slow for you, which is pretty unlikely, then do something else.

So why do I use a lot of append/join in my code? Because sometimes it's actually clearer. Especially when whatever you should concatenate together should be separated by spaces or commas or newlines.

I also faced similar issues when tried to do ng serve. I was able to resolve it as below.
Note:

C:\Windows\system32> is on windows command prompt
C:\apps\workspace\testProj>  is on VS code Terminal (can also be doable in another command prompt)

Following are the steps which I used to resolve this.

Step1. Verify the cli version installed on command prompt (will be Angular CLI global version)

C:\Windows\system32>ng --version

Angular CLI: 8.3.13

If cli was installed earlier, it shows the global cli version.

If cli was not installed, we may get the error
ng is not recognized as an internal or external command

a. (Optional Step) Install Angular CLI global version

C:\Windows\system32>npm install -g @angular/cli
C:\Windows\system32>npm install -g @angular-cli/latest

b. Check version again

C:\Windows\system32>ng --version
Angular CLI: 8.3.13

Step2. Verify the local cli version installed on your angular project(VS code ide or command prompt cd'd to your project project)

C:\apps\workspace\testProj>ng --version
Angular CLI: 7.3.8

Note: Clearly versions are not in sync. Do the following in your angular project

C:\apps\workspace\testProj>ng update @angular/cli        -> important to sync with global cli version

Note: If upgrade donot work using above command (ref: How to upgrade Angular CLI to the latest version) On command prompt, uninstall global angular cli, clean the cache and reinstall the cli

C:\Windows\system32>npm uninstall -g angular-cli
C:\Windows\system32>npm cache clean or npm cache verify #(if npm > 5)
C:\Windows\system32>npm install -g @angular/cli@latest

Now update your local project version, because cli version of your local project is having higher priority than global one when you try to execute your project.

C:\apps\workspace\testProj>rm -rf node_modules
C:\apps\workspace\testProj>npm uninstall --save-dev angular-cli
C:\apps\workspace\testProj>npm install --save-dev @angular/cli@latest
C:\apps\workspace\testProj>npm install
C:\apps\workspace\testProj>ng update @angular/cli

Step3. Verify if local project cli version now in sync with global one

C:\Windows\system32>ng --version
Angular CLI: 8.3.13

C:\apps\workspace\testProj>ng --version
Angular CLI: 8.3.13

Step4.. Revalidate on the project

C:\apps\workspace\testProj>ng serve

Should work now

> S<-S[,-2]
> S
[,1] [,2] [,3] [,4]
[1,]    1    3    4    5
[2,]    2    2    3    4
[3,]    3    1    2    3
[4,]    4    2    1    2
[5,]    5    3    2    1

Just use the command S <- S[,-2] to remove the second column. Similarly to delete a row, for example, to delete the second row use S <- S[-2,].

Update as of npm 5:

As of npm 5.0.0, installed modules are added as a dependency by default, so the --save option is no longer needed. The other save options still exist and are listed in the documentation for npm install.

Original answer:

It won't do anything if you don't have a package.json file. Start by running npm init to create one. Then calls to npm install --save or npm install --save-dev or npm install --save-optional will update the package.json to list your dependencies.

File uploads can not be done this way, no matter how you break it down. If you want to do an ajax/async upload, I would suggest looking into something like Uploadify, or Valums

Another thing that people may find useful when using the develop method is the --user option to install without sudo. Ex:

python setup.py develop --user

instead of

sudo python setup.py develop

Take a look at the write.csv or the write.table functions. You just have to supply the file name the user selects to the file parameter, and the dataframe to the x parameter:

write.csv(x=df, file="myFileName")

set.seed is a base function that it is able to generate (every time you want) together other functions (rnorm, runif, sample) the same random value.

Below an example without set.seed

> set.seed(NULL)

I use addActionListener for JButtons while addItemListener is more convenient for a JToggleButton. Together with if(event.getStateChange()==ItemEvent.SELECTED), in the latter case, I add Events for whenever the JToggleButton is checked/unchecked.

I created it in a more similar way to the SQL, I think it is easier to understand

var list = (from a in listA.AsEnumerable()
            join b in listB.AsEnumerable() on a.id equals b.id into ab
            from c in ab.DefaultIfEmpty()
            where c != null
            select new { id = c.id, name = c.nome }).ToList();

Or you simply manage it like full IIS by using Jexus Manager for IIS Express, an open source project I work on

Start a site and the process will be launched for you.

You can use Google Page Speed API to achieve your task easily. In my current project, I have used Google Page Speed API`s query written in Python to capture screenshots of any Web URL provided and save it to a location. Have a look.

import urllib2
import json
import base64
import sys
import requests
import os
import errno

#   The website's URL as an Input
site = sys.argv[1]
imagePath = sys.argv[2]

#   The Google API.  Remove "&strategy=mobile" for a desktop screenshot
api = "https://www.googleapis.com/pagespeedonline/v1/runPagespeed?screenshot=true&strategy=mobile&url=" + urllib2.quote(site)

#   Get the results from Google
try:
    site_data = json.load(urllib2.urlopen(api))
except urllib2.URLError:
    print "Unable to retreive data"
    sys.exit()

try:
    screenshot_encoded =  site_data['screenshot']['data']
except ValueError:
    print "Invalid JSON encountered."
    sys.exit()

#   Google has a weird way of encoding the Base64 data
screenshot_encoded = screenshot_encoded.replace("_", "/")
screenshot_encoded = screenshot_encoded.replace("-", "+")

#   Decode the Base64 data
screenshot_decoded = base64.b64decode(screenshot_encoded)

if not os.path.exists(os.path.dirname(impagepath)):
    try:
        os.makedirs(os.path.dirname(impagepath))
        except  OSError as exc:
            if exc.errno  != errno.EEXIST:
                raise

#   Save the file
with open(imagePath, 'w') as file_:
    file_.write(screenshot_decoded)

Unfortunately, following are the drawbacks. If these do not matter, you can proceed with Google Page Speed API. It works well.

• The maximum width is 320px
• According to Google API Quota, there is a limit of 25,000 requests per day

Looks like you have a dos line ending file. The clue is the ^M.

You need to re-save the file using Unix line endings.

You might have a dos2unix command line utility that will also do this for you.

easy if its pdf or img use

return (in_Array($file['content-type'], ['image/jpg', 'application/pdf']));

Some of the webservices require you to place request data and metadata separately. For example a remote function may expect that the signed metadata string is included in a URI, while the data is posted in a HTTP-body.

The POST request may semantically look like this:

POST /?AuthId=YOURKEY&Action=WebServiceAction&Signature=rcLXfkPldrYm04 HTTP/1.1
Content-Type: text/tab-separated-values; charset=iso-8859-1
Content-Length: []
Host: webservices.domain.com
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding: identity
User-Agent: Mozilla/3.0 (compatible; Indy Library)

name    id
John    G12N
Sarah   J87M
Bob     N33Y

This approach logically combines QueryString and Body-Post using a single Content-Type which is a "parsing-instruction" for a web-server.

Please note: HTTP/1.1 is wrapped with the #32 (space) on the left and with #10 (Line feed) on the right.

String.IsNullOrEmpty(string value) returns true if the string is null or empty. For reference an empty string is represented by "" (two double quote characters)

String.IsNullOrWhitespace(string value) returns true if the string is null, empty, or contains only whitespace characters such as a space or tab.

To see what characters count as whitespace consult this link: http://msdn.microsoft.com/en-us/library/t809ektx.aspx

You're apparently off by one day, exactly 86400 seconds. Use the number 2209161600 Not the number 2209075200 If you Google the two numbers, you'll find support for the above. I tried your formula but was always coming up 1 day different from my server. It's not obvious from the unix timestamp unless you think in unix instead of human time ;-) but if you double check then you'll see this might be correct.

Here's an extension method for converting a Bitmap to BitmapImage.

    public static BitmapImage ToBitmapImage(this Bitmap bitmap)
    {
        using (var memory = new MemoryStream())
        {
            bitmap.Save(memory, ImageFormat.Png);
            memory.Position = 0;

            var bitmapImage = new BitmapImage();
            bitmapImage.BeginInit();
            bitmapImage.StreamSource = memory;
            bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
            bitmapImage.EndInit();
            bitmapImage.Freeze();

            return bitmapImage;
        }
    }

This is the hardware serial number. To access it on

• Android Q (>= SDK 29) android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE is required. Only system apps can require this permission. If the calling package is the device or profile owner then the READ_PHONE_STATE permission suffices.

• Android 8 and later (>= SDK 26) use android.os.Build.getSerial() which requires the dangerous permission READ_PHONE_STATE. Using android.os.Build.SERIAL returns android.os.Build.UNKNOWN.

• Android 7.1 and earlier (<= SDK 25) and earlier android.os.Build.SERIAL does return a valid serial.

It's unique for any device. If you are looking for possibilities on how to get/use a unique device id you should read here.

For a solution involving reflection without requiring a permission see this answer.

That's a good question! You may get into troubles if you invoke API that uses generics and want to assign or return that result with a different subtype of the generic type. Java 8 helps to transform:

    List<String> input = new LinkedList<>(Arrays.asList("a", "b", "c"));
    List<CharSequence> result;
    
//    result = input; // <-- Type mismatch: cannot convert from List<String> to List<CharSequence>
    result = input.stream().collect(Collectors.toList());
    
    System.out.println(result);

WebSite : It generates app_code folder automatically and if you publish it on the server and after that if you do some changes in any particular file or page than you don't have to do compile all files.

Web Application It generates solutions file automatically which website doesn't generate and if you change in one file than you have to compile full project to reflects its changes.

You can do it calling setRowSelectionInterval :

table.setRowSelectionInterval(0, 0);

to select the first row.

You can use the popover event, and control the width by attribute 'data-width'

$('[data-toggle="popover-huongdan"]').popover({ html: true });_x000D_
$('[data-toggle="popover-huongdan"]').on("shown.bs.popover", function () {_x000D_
    var width = $(this).attr("data-width") == undefined ? 276 : parseInt($(this).attr("data-width"));_x000D_
    $("div[id^=popover]").css("max-width", width);_x000D_
});

 <a class="position-absolute" href="javascript:void(0);" data-toggle="popover-huongdan" data-trigger="hover" data-width="500" title="title-popover" data-content="html-content-code">_x000D_
 <i class="far fa-question-circle"></i>_x000D_
 </a>

The safe and fastest way is to use Bit Masking before cast...

int MyInt = (int) ( MyLong & 0xFFFFFFFF )

The Bit Mask ( 0xFFFFFFFF ) value will depend on the size of Int because Int size is dependent on machine.

The install:install goal is provided by «Apache Maven Install Plugin»:

Apache Maven Install Plugin

The Install Plugin is used during the install phase to add artifact(s) to the local repository. The Install Plugin uses the information in the POM (groupId, artifactId, version) to determine the proper location for the artifact within the local repository.

The local repository is the local cache where all artifacts needed for the build are stored. By default, it is located within the user's home directory (~/.m2/repository) but the location can be configured in ~/.m2/settings.xml using the <localRepository> element.

— Apache Maven Install Plugin - Introduction.

Having said that, the exact goal purpose:

install:install is used to automatically install the project's main artifact (the JAR, WAR or EAR), its POM and any attached artifacts (sources, javadoc, etc) produced by a particular project.

— Apache Maven Install Plugin - Introduction.

For additional details on the goal, please refer to the Apache Maven Install Plugin - install:install page.

For additional details on the build lifecycle in general and on which place the goal has in the build lifecycle, please refer to the Maven – Introduction to the Build Lifecycle page.

Here is a nice tutorial, it is what you need. (Source: coursesweb.net/php-mysql)

Register and show online users and visitors

Count Online users and visitors using a MySQL table

In this tutorial you can learn how to register, to count, and display in your webpage the number of online users and visitors. The principle is this: each user / visitor is registered in a text file or database. Every time a page of the website is accessed, the php script deletes all records older than a certain time (eg 2 minutes), adds the current user / visitor and takes the number of records left to display.

You can store the online users and visitors in a file on the server, or in a MySQL table. In this case, I think that using a text file to add and read the records is faster than storing them into a MySQL table, which requires more requests.

First it's presented the method with recording in a text file on the server, than the method with MySQL table.

To download the files with the scripts presented in this tutorial, click -> Count Online Users and Visitors.

• Both scripts can be included in ".php" files (with include()), or in ".html" files (with <script>), as you can see in the examples presented at the bottom of this page; but the server must run PHP.

Storing online users and visitors in a text file

To add records in a file on the server with PHP you must set CHMOD 0766 (or CHMOD 0777) permissions to that file, so the PHP can write data in it.

1. Create a text file on your server (for example, named userson.txt) and give it CHMOD 0777 permissions (in your FTP application, right click on that file, choose Properties, then select Read, Write, and Execute options).
2. Create a PHP file (named usersontxt.php) having the code below, then copy this php file in the same directory as userson.txt.

The code for usersontxt.php;

<?php
// Script Online Users and Visitors - http://coursesweb.net/php-mysql/
if(!isset($_SESSION)) session_start();        // start Session, if not already started

$filetxt = 'userson.txt';  // the file in which the online users /visitors are stored
$timeon = 120;             // number of secconds to keep a user online
$sep = '^^';               // characters used to separate the user name and date-time
$vst_id = '-vst-';        // an identifier to know that it is a visitor, not logged user

/*
 If you have an user registration script,
 replace $_SESSION['nume'] with the variable in which the user name is stored.
 You can get a free registration script from:  http://coursesweb.net/php-mysql/register-login-script-users-online_s2
*/

// get the user name if it is logged, or the visitors IP (and add the identifier)

    $uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $_SERVER['SERVER_ADDR']. $vst_id;

$rgxvst = '/^([0-9\.]*)'. $vst_id. '/i';         // regexp to recognize the line with visitors
$nrvst = 0;                                       // to store the number of visitors

// sets the row with the current user /visitor that must be added in $filetxt (and current timestamp)

    $addrow[] = $uvon. $sep. time();

// check if the file from $filetxt exists and is writable

    if(is_writable($filetxt)) {
      // get into an array the lines added in $filetxt
      $ar_rows = file($filetxt, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
      $nrrows = count($ar_rows);

            // number of rows

  // if there is at least one line, parse the $ar_rows array

      if($nrrows>0) {
        for($i=0; $i<$nrrows; $i++) {
          // get each line and separate the user /visitor and the timestamp
          $ar_line = explode($sep, $ar_rows[$i]);
      // add in $addrow array the records in last $timeon seconds
          if($ar_line[0]!=$uvon && (intval($ar_line[1])+$timeon)>=time()) {
            $addrow[] = $ar_rows[$i];
          }
        }
      }
    }

$nruvon = count($addrow);                   // total online
$usron = '';                                    // to store the name of logged users
// traverse $addrow to get the number of visitors and users
for($i=0; $i<$nruvon; $i++) {
 if(preg_match($rgxvst, $addrow[$i])) $nrvst++;       // increment the visitors
 else {
   // gets and stores the user's name
   $ar_usron = explode($sep, $addrow[$i]);
   $usron .= '<br/> - <i>'. $ar_usron[0]. '</i>';
 }
}
$nrusr = $nruvon - $nrvst;              // gets the users (total - visitors)

// the HTML code with data to be displayed
$reout = '<div id="uvon"><h4>Online: '. $nruvon. '</h4>Visitors: '. $nrvst. '<br/>Users: '. $nrusr. $usron. '</div>';

// write data in $filetxt
if(!file_put_contents($filetxt, implode("\n", $addrow))) $reout = 'Error: Recording file not exists, or is not writable';

// if access from <script>, with GET 'uvon=showon', adds the string to return into a JS statement
// in this way the script can also be included in .html files
if(isset($_GET['uvon']) && $_GET['uvon']=='showon') $reout = "document.write('$reout');";

echo $reout;             // output /display the result
?>

3. If you want to include the script above in a ".php" file, add the following code in the place you want to show the number of online users and visitors:

4.To show the number of online visitors /users in a ".html" file, use this code:

<script type="text/javascript" src="usersontxt.php?uvon=showon"></script>

This script (and the other presented below) works with $_SESSION. At the beginning of the PHP file in which you use it, you must add: session_start();. Count Online users and visitors using a MySQL table

To register, count and show the number of online visitors and users in a MySQL table, require to perform three SQL queries: Delete the records older than a certain time. Insert a row with the new user /visitor, or, if it is already inserted, Update the timestamp in its column. Select the remaining rows. Here's the code for a script that uses a MySQL table (named "userson") to store and display the Online Users and Visitors.

1. First we create the "userson" table, with 2 columns (uvon, dt). In the "uvon" column is stored the name of the user (if logged in) or the visitor's IP. In the "dt" column is stored a number with the timestamp (Unix time) when the page is accessed.

• Add the following code in a php file (for example, named "create_userson.php"):

The code for create_userson.php:

<?php
header('Content-type: text/html; charset=utf-8');

// HERE add your data for connecting to MySQ database
$host = 'localhost';           // MySQL server address
$user = 'root';                // User name
$pass = 'password';            // User`s password
$dbname = 'database';          // Database name

// connect to the MySQL server
$conn = new mysqli($host, $user, $pass, $dbname);

// check connection
if (mysqli_connect_errno()) exit('Connect failed: '. mysqli_connect_error());

// sql query for CREATE "userson" TABLE
$sql = "CREATE TABLE `userson` (
 `uvon` VARCHAR(32) PRIMARY KEY,
 `dt` INT(10) UNSIGNED NOT NULL
 ) CHARACTER SET utf8 COLLATE utf8_general_ci"; 

// Performs the $sql query on the server to create the table
if ($conn->query($sql) === TRUE) echo 'Table "userson" successfully created';
else echo 'Error: '. $conn->error;

$conn->close();
?>

2. Now we create the script that Inserts, Deletes, and Selects data in the userson table (For explanations about the code, see the comments in script).

• Add the code below in another php file (named usersmysql.php): In both file you must add your personal data for connecting to MySQL database, in the variables: $host, $user, $pass, and $dbname .

The code for usersmysql.php:

<?php
// Script Online Users and Visitors - coursesweb.net/php-mysql/
if(!isset($_SESSION)) session_start();         // start Session, if not already started

// HERE add your data for connecting to MySQ database
$host = 'localhost';           // MySQL server address
$user = 'root';                // User name
$pass = 'password';            // User`s password
$dbname = 'database';          // Database name

/*
 If you have an user registration script,
 replace $_SESSION['nume'] with the variable in which the user name is stored.
 You can get a free registration script from:  http://coursesweb.net/php-mysql/register-login-script-users-online_s2
*/

// get the user name if it is logged, or the visitors IP (and add the identifier)
$vst_id = '-vst-';         // an identifier to know that it is a visitor, not logged user
$uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $_SERVER['SERVER_ADDR']. $vst_id;

$rgxvst = '/^([0-9\.]*)'. $vst_id. '/i';         // regexp to recognize the rows with visitors
$dt = time();                                    // current timestamp
$timeon = 120;             // number of secconds to keep a user online
$nrvst = 0;                                     // to store the number of visitors
$nrusr = 0;                                     // to store the number of usersrs
$usron = '';                                    // to store the name of logged users

// connect to the MySQL server
$conn = new mysqli($host, $user, $pass, $dbname);

// Define and execute the Delete, Insert/Update, and Select queries
$sqldel = "DELETE FROM `userson` WHERE `dt`<". ($dt - $timeon);
$sqliu = "INSERT INTO `userson` (`uvon`, `dt`) VALUES ('$uvon', $dt) ON DUPLICATE KEY UPDATE `dt`=$dt";
$sqlsel = "SELECT * FROM `userson`";

// Execute each query
if(!$conn->query($sqldel)) echo 'Error: '. $conn->error;
if(!$conn->query($sqliu)) echo 'Error: '. $conn->error;
$result = $conn->query($sqlsel);

// if the $result contains at least one row
if ($result->num_rows > 0) {
  // traverse the sets of results and set the number of online visitors and users ($nrvst, $nrusr)
  while($row = $result->fetch_assoc()) {
    if(preg_match($rgxvst, $row['uvon'])) $nrvst++;       // increment the visitors
    else {
      $nrusr++;                   // increment the users
      $usron .= '<br/> - <i>'.$row['uvon']. '</i>';          // stores the user's name
    }
  }
}

$conn->close();                  // close the MySQL connection

// the HTML code with data to be displayed
$reout = '<div id="uvon"><h4>Online: '. ($nrusr+$nrvst). '</h4>Visitors: '. $nrvst. '<br/>Users: '. $nrusr. $usron. '</div>';

// if access from <script>, with GET 'uvon=showon', adds the string to return into a JS statement
// in this way the script can also be included in .html files
if(isset($_GET['uvon']) && $_GET['uvon']=='showon') $reout = "document.write('$reout');";

echo $reout;             // output /display the result
?>

3. After you have created these two php files on your server, run the "create_userson.php" on your browser to create the "userson" table.

4. Include the usersmysql.php file in the php file in which you want to display the number of online users and visitors.

5. Or, if you want to insert it in a ".html" file, add this code:

Examples using these scripts

• Including the "usersontxt.php` in a php file:

<!doctype html>

• Including the "usersmysql.php" in a html file:

While it's not hard to do this manually using BufferedReader and InputStreamReader, I'd use Guava:

List<String> lines = Files.readLines(file, Charsets.UTF_8);

You can then do whatever you like with those lines.

EDIT: Note that this will read the whole file into memory in one go. In most cases that's actually fine - and it's certainly simpler than reading it line by line, processing each line as you read it. If it's an enormous file, you may need to do it that way as per T.J. Crowder's answer.

I was getting this error while posting a FormData object because I was not setting up the ajax call correctly. Setup below fixed my issue.

var myformData = new FormData();        
myformData.append('leadid', $("#leadid").val());
myformData.append('date', $(this).val());
myformData.append('time', $(e.target).prev().val());

$.ajax({
    method: 'post',
    processData: false,
    contentType: false,
    cache: false,
    data: myformData,
    enctype: 'multipart/form-data',
    url: 'include/ajax.php',
    success: function (response) {
        $("#subform").html(response).delay(4000).hide(1); 
    }
});

Update

All the previous reviews were tested by me, but there was no solution. But I did not give up.

SOLUTION

Uncomment the following lines in my NGINX configuration

   [/etc/nginx/site-avaible/{sitename}.conf]

The same code should follow in the site-enable folder

  #fastcgi_param SCRIPT_FILENAME $ document_root $ fastcgi_script_name;

And comment this:

  fastcgi_param SCRIPT_FILENAME / www / {namesite} / public_html $ fastcgi_script_name;

I changed several times from the original:

   #fastcgi_pass unix: /var/php-nginx/9882989289032.sock;

Going back to this:

   #fastcgi_pass 127.0.0.1:9007;

And finally I found what worked ...

   fastcgi_pass localhost: 8004;

I also recommend these lines...

   #fastcgi_index index.php;
   #include fastcgi_params;

And even the FastCGI timeout (only to improve performance)

  fastcgi_read_timeout 3000;

During the process, I checked the NGINX log for all modifications. (This is very important because it shows the wrong parameter.) In my case it is like this, but it depends on the configuration:

  error_log/var/log/nginx/{site}_error_log;

Test the NGINX Configuration

 nginx -t

Attention this is one of the options ... Well on the same server, what did not work on this site works on others ... So keep in mind that the settings depends on the platform.

In this case it was for Joomla CMS.

You must of already called the session start maybe being called again through an include?

if( ! $_SESSION)
{
    session_start();
}  

If you have queries to a DBMS for which the locality is quite restricted (say, a user only fires selects with a 'where username = $my_username') it makes sense to put all the usernames starting with A-M on one server and all from N-Z on the other. By this you get near linear scaling for some queries.

Long story short: Sharding is basically the process of distributing tables onto different servers in order to balance the load onto both equally.

Of course, it's so much more complicated in reality. :)

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

Adding comment for anyone using Plesk having issues with any of the above as it was driving me crazy, setting session.gc_maxlifetime from your PHP script wont work as Plesk has it's own garbage collection script run from cron.

I used the solution posted on the link below of moving the cron job from hourly to daily to avoid this issue, then the top answer above should work:

mv /etc/cron.hourly/plesk-php-cleanuper /etc/cron.daily/

https://websavers.ca/plesk-php-sessions-timing-earlier-expected

Nothing stops you from doing

moveUp = moveDown = moveLeft = moveRight = mouseDown = touchDown = false;

Check this example

var a, b, c;_x000D_
a = b = c = 10;_x000D_
console.log(a + b + c)

If you want to make sure your div is not visible by default use ng-cloak class instead. It will work properly with ngShow directive:

<div><div ng-show="myvalue" class="ng-cloak">Here I am</div></div>

Demo: http://jsfiddle.net/4WK7R/4/

If you just use round then the two end numbers (1 and 9) will occur less frequently, to get an even distribution of integers between 1 and 9 then:

SELECT MOD(Round(DBMS_RANDOM.Value(1, 99)), 9) + 1 FROM DUAL

You could add in your code a call system with the new definition:

sprintf(newdef,"export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:%s:%s",ld1,ld2);
system(newdef);

But, I don't know it that is the rigth solution but it works.

inside the Form, You can use this code. Replace your variable name (i use $variable)

<input type="text" value="<?php echo (isset($variable))?$variable:'';?>">

I did it using Extension Functions in kotlin

fun String.toDate(dateFormat: String = "yyyy-MM-dd HH:mm:ss", timeZone: TimeZone = TimeZone.getTimeZone("UTC")): Date {
    val parser = SimpleDateFormat(dateFormat, Locale.getDefault())
    parser.timeZone = timeZone
    return parser.parse(this)
}

fun Date.formatTo(dateFormat: String, timeZone: TimeZone = TimeZone.getDefault()): String {
    val formatter = SimpleDateFormat(dateFormat, Locale.getDefault())
    formatter.timeZone = timeZone
    return formatter.format(this)
}

Usage:

"2018-09-10 22:01:00".toDate().formatTo("dd MMM yyyy")

Output: "11 Sep 2018"

Note:

Ensure the proper validation.

STEP 1

Go to properties of your project ( with Alt+Enter or righ-click )

STEP 2

check on Apache Tomcat v7.0 under Targeted Runtime and it works.

I am using CentOS and had same problem.

I changed /usr/local/bin/composer to /usr/bin/composer and it worked.

Run below command :

You have it working.

Interesting discussion regarding Designing REST API for returning count of multiple objects: https://groups.google.com/g/api-craft/c/qbI2QRrpFew/m/h30DYnrqEwAJ?pli=1

As an API consumer, I would expect each count value to be represented either as a subresource to the countable resource (i.e. GET /tasks/count for a count of tasks), or as a field in a bigger aggregation of metadata related to the concerned resource (i.e. GET /tasks/metadata). By scoping related endpoints under the same parent resource (i.e. /tasks), the API becomes intuitive, and the purpose of an endpoint can (usually) be inferred from its path and HTTP method.

Additional thoughts:

1. If each individual count is only useful in combination with other counts (for a statistics dashboard, for example), you could possibly expose a single endpoint which aggregates and returns all counts at once.
2. If you have an existing endpoint for listing all resources (i.e. GET /tasks for listing all tasks), the count could be included in the response as metadata, either as HTTP headers or in the response body. Doing this will incur unnecessary load on the API, which might be negligible depending on your use case.

To answer the last part of your question about any extensions that can save changes, there is hotfix

It allows you to save changes from Chrome Dev Tools directly to GitHub. From there you can set up a post-receive hook on GitHub to automatically update your website.

If you have access to the server then you can use

select local_tcp_port from sys.dm_exec_connections where local_tcp_port is not null

For full details see port number of SQL Server

Take a look at the following system stored procedures, which you can run in SQLServer Management Studio (SSMS):

• sp_who
• sp_lock

Also, in SSMS, you can view locks and processes in different ways:

Different versions of SSMS put the activity monitor in different places. For example, SSMS 2008 and 2012 have it in the context menu when you right-click on a server node.

VS 2015 changes this. It added a .vs folder to my web project and the applicationhost.config was in there. I made the changes suggested (window authentication = true, anon=false) and it started delivering a username instead of a blank.

Database tables

To demonstrate how the USING and ON clauses work, let's assume we have the following post and post_comment database tables, which form a one-to-many table relationship via the post_id Foreign Key column in the post_comment table referencing the post_id Primary Key column in the post table:

The parent post table has 3 rows:

| post_id | title     |
|---------|-----------|
| 1       | Java      |
| 2       | Hibernate |
| 3       | JPA       |

and the post_comment child table has the 3 records:

| post_comment_id | review    | post_id |
|-----------------|-----------|---------|
| 1               | Good      | 1       |
| 2               | Excellent | 1       |
| 3               | Awesome   | 2       |

The JOIN ON clause using a custom projection

Traditionally, when writing an INNER JOIN or LEFT JOIN query, we happen to use the ON clause to define the join condition.

For example, to get the comments along with their associated post title and identifier, we can use the following SQL projection query:

SELECT
   post.post_id,
   title,
   review
FROM post
INNER JOIN post_comment ON post.post_id = post_comment.post_id
ORDER BY post.post_id, post_comment_id

And, we get back the following result set:

| post_id | title     | review    |
|---------|-----------|-----------|
| 1       | Java      | Good      |
| 1       | Java      | Excellent |
| 2       | Hibernate | Awesome   |

The JOIN USING clause using a custom projection

When the Foreign Key column and the column it references have the same name, we can use the USING clause, like in the following example:

SELECT
  post_id,
  title,
  review
FROM post
INNER JOIN post_comment USING(post_id)
ORDER BY post_id, post_comment_id

And, the result set for this particular query is identical to the previous SQL query that used the ON clause:

| post_id | title     | review    |
|---------|-----------|-----------|
| 1       | Java      | Good      |
| 1       | Java      | Excellent |
| 2       | Hibernate | Awesome   |

The USING clause works for Oracle, PostgreSQL, MySQL, and MariaDB. SQL Server doesn't support the USING clause, so you need to use the ON clause instead.

The USING clause can be used with INNER, LEFT, RIGHT, and FULL JOIN statements.

SQL JOIN ON clause with SELECT *

Now, if we change the previous ON clause query to select all columns using SELECT *:

SELECT *
FROM post
INNER JOIN post_comment ON post.post_id = post_comment.post_id
ORDER BY post.post_id, post_comment_id

We are going to get the following result set:

| post_id | title     | post_comment_id | review    | post_id |
|---------|-----------|-----------------|-----------|---------|
| 1       | Java      | 1               | Good      | 1       |
| 1       | Java      | 2               | Excellent | 1       |
| 2       | Hibernate | 3               | Awesome   | 2       |

As you can see, the post_id is duplicated because both the post and post_comment tables contain a post_id column.

SQL JOIN USING clause with SELECT *

On the other hand, if we run a SELECT * query that features the USING clause for the JOIN condition:

SELECT *
FROM post
INNER JOIN post_comment USING(post_id)
ORDER BY post_id, post_comment_id

We will get the following result set:

| post_id | title     | post_comment_id | review    |
|---------|-----------|-----------------|-----------|
| 1       | Java      | 1               | Good      |
| 1       | Java      | 2               | Excellent |
| 2       | Hibernate | 3               | Awesome   |

You can see that this time, the post_id column is deduplicated, so there is a single post_id column being included in the result set.

Conclusion

If the database schema is designed so that Foreign Key column names match the columns they reference, and the JOIN conditions only check if the Foreign Key column value is equal to the value of its mirroring column in the other table, then you can employ the USING clause.

Otherwise, if the Foreign Key column name differs from the referencing column or you want to include a more complex join condition, then you should use the ON clause instead.

Doing this from the app delegate is NOT recommended. AppDelegate manages the app life cycle that relate to launching, suspending, terminating and so on. I suggest doing this from your initial view controller in the viewDidAppear. You can self.presentViewController and self.dismissViewController from the login view controller. Store a bool key in NSUserDefaults to see if it's launching for the first time.

Don't create mistakes on your server by changing everything. If you have windows prompt to logon when using Windows Authentication on 2008 R2, just go to Providers and move UP NTLM for each your application. When Negotiate is first one in the list, Windows Authentication can stop to work property for specific application on 2008 R2 and you can be prompted to enter username and password than never work. That sometime happens when you made an update of your application. Just be sure than NTLM is first on the list and you will never see this problem again.

Uninstall jdk8, install jdk7, then reinstall jdk8.

My approach to switching between them (in .profile) :

export JAVA_7_HOME=$(/usr/libexec/java_home -v1.7)
export JAVA_8_HOME=$(/usr/libexec/java_home -v1.8)
export JAVA_9_HOME=$(/usr/libexec/java_home -v9)

alias java7='export JAVA_HOME=$JAVA_7_HOME'
alias java8='export JAVA_HOME=$JAVA_8_HOME'
alias java9='export JAVA_HOME=$JAVA_9_HOME'

#default java8
export JAVA_HOME=$JAVA_8_HOME

Then you can simply type java7 or java8 in a terminal to switch versions.

Genial arrow module exists

 2017-04-05T11:17:34.431397+00:00

You should specify column names as below. It's good practice and probably solve your problem

insert into abc.employees (col1,col2) 
select col1,col2 from employees where employee_id=100; 

EDIT:

As you said employees has 112 columns (sic!) try to run below select to compare both tables' columns

select * 
from ALL_TAB_COLUMNS ATC1
left join ALL_TAB_COLUMNS ATC2 on ATC1.COLUMN_NAME = ATC1.COLUMN_NAME 
                               and  ATC1.owner = UPPER('2nd owner')
where ATC1.owner = UPPER('abc')
and ATC2.COLUMN_NAME is null
AND ATC1.TABLE_NAME = 'employees'

and than you should upgrade your tables to have the same structure.

I also had to set the following META tag:

<meta http-equiv="X-UA-Compatible" content="IE=edge"> 

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

Updated for Swift 3:

var escapedAddress = address.addingPercentEncoding(
    withAllowedCharacters: CharacterSet.urlQueryAllowed)

The fork(),vfork() and clone() all call the do_fork() to do the real work, but with different parameters.

asmlinkage int sys_fork(struct pt_regs regs)
{
    return do_fork(SIGCHLD, regs.esp, &regs, 0);
}

asmlinkage int sys_clone(struct pt_regs regs)
{
    unsigned long clone_flags;
    unsigned long newsp;

    clone_flags = regs.ebx;
    newsp = regs.ecx;
    if (!newsp)
        newsp = regs.esp;
    return do_fork(clone_flags, newsp, &regs, 0);
}
asmlinkage int sys_vfork(struct pt_regs regs)
{
    return do_fork(CLONE_VFORK | CLONE_VM | SIGCHLD, regs.esp, &regs, 0);
}
#define CLONE_VFORK 0x00004000  /* set if the parent wants the child to wake it up on mm_release */
#define CLONE_VM    0x00000100  /* set if VM shared between processes */

SIGCHLD means the child should send this signal to its father when exit.

For fork, the child and father has the independent VM page table, but since the efficiency, fork will not really copy any pages, it just set all the writeable pages to readonly for child process. So when child process want to write something on that page, an page exception happen and kernel will alloc a new page cloned from the old page with write permission. That's called "copy on write".

For vfork, the virtual memory is exactly by child and father---just because of that, father and child can't be awake concurrently since they will influence each other. So the father will sleep at the end of "do_fork()" and awake when child call exit() or execve() since then it will own new page table. Here is the code(in do_fork()) that the father sleep.

if ((clone_flags & CLONE_VFORK) && (retval > 0))
down(&sem);
return retval;

Here is the code(in mm_release() called by exit() and execve()) which awake the father.

up(tsk->p_opptr->vfork_sem);

For sys_clone(), it is more flexible since you can input any clone_flags to it. So pthread_create() call this system call with many clone_flags:

int clone_flags = (CLONE_VM | CLONE_FS | CLONE_FILES | CLONE_SIGNAL | CLONE_SETTLS | CLONE_PARENT_SETTID | CLONE_CHILD_CLEARTID | CLONE_SYSVSEM);

Summary: the fork(),vfork() and clone() will create child processes with different mount of sharing resource with the father process. We also can say the vfork() and clone() can create threads(actually they are processes since they have independent task_struct) since they share the VM page table with father process.

I realise that this article may be outdated but still I would like to ask smithsv to correct his source code, it contains many mistakes, I managed to correct most of them but still don't know what kind of object x509 could be.Here is the source code as I think is should be:

        KeyStore ks = KeyStore.getInstance( "pkcs12" );
        ks.load( new FileInputStream( cert.pfx ), "passwrd".toCharArray() );

        KeyStore jks = KeyStore.getInstance( "JKS" );
        jks.load( null );

        for( Enumeration t = ks.aliases(); t.hasMoreElements(); ) {
            String alias = (String )t.nextElement();
            System.out.println( "@:" + alias );
            if( ks.isKeyEntry( alias ) ) {
                Certificate[] a = ks.getCertificateChain( alias );

                    jks.setCertificateEntry( x509Cert.getSubjectDN().toString(), x509 );

                System.out.println( ks.getCertificateAlias( x509 ) );
                System.out.println( "ok" );

        tmf.init( jks );

        SSLContext ctx = SSLContext.getInstance( "TLS" );
        ctx.init( kmf.getKeyManagers(), tmf.getTrustManagers(), null );

If you just want the response as text and don't want to convert it into JSON, use https://developer.mozilla.org/en-US/docs/Web/API/Body/text and then then it to get the actual result of the promise:

fetch('city-market.md')
  .then(function(response) {
    response.text().then((s) => console.log(s));
  });

or

fetch('city-market.md')
  .then(function(response) {
    return response.text();
  })
  .then(function(myText) {
    console.log(myText);
  });

Try to use document.createEvent described here https://developer.mozilla.org/en-US/docs/Web/API/document.createEvent

The code for function that simulates click should look something like this:

function simulateClick() {
  var evt = document.createEvent("MouseEvents");
  evt.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);
  var a = document.getElementById("gift-close"); 
  a.dispatchEvent(evt);      
}

EDIT: This is now part of MoreLINQ.

What you need is a "distinct-by" effectively. I don't believe it's part of LINQ as it stands, although it's fairly easy to write:

public static IEnumerable<TSource> DistinctBy<TSource, TKey>
    (this IEnumerable<TSource> source, Func<TSource, TKey> keySelector)
{
    HashSet<TKey> seenKeys = new HashSet<TKey>();
    foreach (TSource element in source)
    {
        if (seenKeys.Add(keySelector(element)))
        {
            yield return element;
        }
    }
}

So to find the distinct values using just the Id property, you could use:

var query = people.DistinctBy(p => p.Id);

And to use multiple properties, you can use anonymous types, which implement equality appropriately:

var query = people.DistinctBy(p => new { p.Id, p.Name });

Untested, but it should work (and it now at least compiles).

It assumes the default comparer for the keys though - if you want to pass in an equality comparer, just pass it on to the HashSet constructor.

Just do the following change

[EDITED] It's seems you earlier have redefined "list", using it as a variable name, like this:

list = set([1,2,3,4]) # oops
#...
first_list = [1,2,3,4]
my_set=set(first_list)
my_list = list(my_set)

And you'l get

Traceback (most recent call last):
  File "<console>", line 1, in <module>
TypeError: 'set' object is not callable

The following code can cause similar error:

  using (var session = SessionFactory.OpenSession())
  using (var tx = session.BeginTransaction())
  {
      movie = session.Get<Movie>(movieId);
      tx.Commit();
  }
  Assert.That(movie.Actors.Count == 1);

You can fix it simply:

  using (var session = SessionFactory.OpenSession())
  using (var tx = session.BeginTransaction())
  {
      movie = session.Get<Movie>(movieId);
      Assert.That(movie.Actors.Count == 1);
      tx.Commit();
  }

Install it via this command

sudo apt-get install php5-gd

this worked for me.

A bit late to the party here but here's how simple this is:

ViewBag.Countries = new SelectList(countries.GetCountries(), "id", "countryName", "82");

this uses my method getcountries to populate a model called countries, obviousley you would replace this with whatever your datasource is, a model etc, then sets the id as the value in the selectlist. then just add the last param, in this case "82" to select the default selected item.

[edit] Here's how to use this in Razor:

@Html.DropDownListFor(model => model.CountryId, (IEnumerable<SelectListItem>)ViewBag.Countries, new { @class = "form-control" })

Important: Also, 1 other thing to watch out for, Make sure the model field that you use to store the selected Id (in this case model.CountryId) from the dropdown list is nullable and is set to null on the first page load. This one gets me every time.

Hope this saves someone some time.

Your code works, apart from setting up the connection with the SMTP server. You need a running mail (SMTP) server to send you email for you.

Here is your modified code. I commented out the parts that are not needed and changed the Session creation so it takes an Authenticator. Now just find out the SMPT_HOSTNAME, USERNAME and PASSWORD you want to use (your Internet provider usually provides them).

I always do it like this (using a remote SMTP server I know) because running a local mailserver is not that trivial under Windows (it's apparently quite easy under Linux).

import java.util.*;

import javax.mail.*;
import javax.mail.internet.*;

//import javax.activation.*;

public class SendEmail {

    private static String SMPT_HOSTNAME = "";
    private static String USERNAME = "";
    private static String PASSWORD = "";

    public static void main(String[] args) {

        // Recipient's email ID needs to be mentioned.
        String to = "[email protected]";

        // Sender's email ID needs to be mentioned
        String from = "[email protected]";

        // Assuming you are sending email from localhost
        // String host = "localhost";

        // Get system properties
        Properties properties = System.getProperties();

        // Setup mail server
        properties.setProperty("mail.smtp.host", SMPT_HOSTNAME);

        // Get the default Session object.
        // Session session = Session.getDefaultInstance(properties);

        // create a session with an Authenticator
        Session session = Session.getInstance(properties, new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(USERNAME, PASSWORD);
            }
        });

        try {
            // Create a default MimeMessage object.
            MimeMessage message = new MimeMessage(session);

            // Set From: header field of the header.
            message.setFrom(new InternetAddress(from));

            // Set To: header field of the header.
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(
                    to));

            // Set Subject: header field
            message.setSubject("This is the Subject Line!");

            // Now set the actual message
            message.setText("This is actual message");

            // Send message
            Transport.send(message);
            System.out.println("Sent message successfully....");
        } catch (MessagingException mex) {
            mex.printStackTrace();
        }
    }
}

You can use a resource key like this:

<UserControl.Resources>
    <SolidColorBrush x:Key="{x:Static local:Foo.MyKey}">Blue</SolidColorBrush>
</UserControl.Resources>
<Grid Background="{StaticResource {x:Static local:Foo.MyKey}}" />

public partial class Foo : UserControl
{
    public Foo()
    {
        InitializeComponent();
        var brush = (SolidColorBrush)FindResource(MyKey);
    }

    public static ResourceKey MyKey { get; } = CreateResourceKey();

    private static ComponentResourceKey CreateResourceKey([CallerMemberName] string caller = null)
    {
        return new ComponentResourceKey(typeof(Foo), caller); ;
    }
}

For the real differences, we can find it in code, but I can't find the implement of the default behavior of the isinstance().

However we can get the similar one abc.__instancecheck__ according to __instancecheck__.

From above abc.__instancecheck__, after using test below:

# file tree
# /test/__init__.py
# /test/aaa/__init__.py
# /test/aaa/aa.py
class b():
pass

# /test/aaa/a.py
import sys
sys.path.append('/test')

from aaa.aa import b
from aa import b as c

d = b()

print(b, c, d.__class__)
for i in [b, c, object]:
    print(i, '__subclasses__',  i.__subclasses__())
    print(i, '__mro__', i.__mro__)
    print(i, '__subclasshook__', i.__subclasshook__(d.__class__))
    print(i, '__subclasshook__', i.__subclasshook__(type(d)))
print(isinstance(d, b))
print(isinstance(d, c))

<class 'aaa.aa.b'> <class 'aa.b'> <class 'aaa.aa.b'>
<class 'aaa.aa.b'> __subclasses__ []
<class 'aaa.aa.b'> __mro__ (<class 'aaa.aa.b'>, <class 'object'>)
<class 'aaa.aa.b'> __subclasshook__ NotImplemented
<class 'aaa.aa.b'> __subclasshook__ NotImplemented
<class 'aa.b'> __subclasses__ []
<class 'aa.b'> __mro__ (<class 'aa.b'>, <class 'object'>)
<class 'aa.b'> __subclasshook__ NotImplemented
<class 'aa.b'> __subclasshook__ NotImplemented
<class 'object'> __subclasses__ [..., <class 'aaa.aa.b'>, <class 'aa.b'>]
<class 'object'> __mro__ (<class 'object'>,)
<class 'object'> __subclasshook__ NotImplemented
<class 'object'> __subclasshook__ NotImplemented
True
False

I get this conclusion, For type:

# according to `abc.__instancecheck__`, they are maybe different! I have not found negative one 
type(INSTANCE) ~= INSTANCE.__class__
type(CLASS) ~= CLASS.__class__

For isinstance:

# guess from `abc.__instancecheck__`
return any(c in cls.__mro__ or c in cls.__subclasses__ or cls.__subclasshook__(c) for c in {INSTANCE.__class__, type(INSTANCE)})

BTW: better not to mix use relative and absolutely import, use absolutely import from project_dir( added by sys.path)

You need to pass a function to setTimeout

$(window).load(function () {
    window.setTimeout(function () {
        window.location.href = "https://www.google.co.in";
    }, 5000)
});

If these strings are currently in the db, you can skip php by using mysql's STR_TO_DATE() function.

I assume the strings use a format like month/day/year where month and day are always 2 digits, and year is 4 digits.

UPDATE some_table
   SET new_column = STR_TO_DATE(old_column, '%m/%d/%Y')

You can support other date formats by using other format specifiers.

Great question and great idea, but in SQL you'll need to do this:

For data type datetime, something like this-

declare @BeginDate    datetime = '1/1/2016',
        @EndDate      datetime = '12/1/2016'
create table #months (dates datetime)
declare @var datetime = @BeginDate
   while @var < dateadd(MONTH, +1, @EndDate)
   Begin
          insert into #months Values(@var)
          set @var = Dateadd(MONTH, +1, @var)
   end

If all you really want is numbers, do this-

create table #numbas (digit int)
declare @var int = 1        --your starting digit
    while @var <= 12        --your ending digit
    begin
        insert into #numbas Values(@var)
        set @var = @var +1
    end

The following syntax can also be used if the array is not named (just the array is passed to the template):

  <ul id="luke_should_be_here">
  {{this.1.name}}
  </ul>

borderColor on any view(or UIView Subclass) could also be set using storyboard with a little bit of coding and this approach could be really handy if you're setting border color on multiple UI Objects.

Below are the steps how to achieve it,

1. Create a category on CALayer class. Declare a property of type UIColor with a suitable name, I'll name it as borderUIColor .
2. Write the setter and getter for this property.
3. In the 'Setter' method just set the "borderColor" property of layer to the new colors CGColor value.
4. In the 'Getter' method return UIColor with layer's borderColor.

P.S: Remember, Categories can't have stored properties. 'borderUIColor' is used as a calculated property, just as a reference to achieve what we're focusing on.

Please have a look at the below code sample;

Objective C:

Interface File:

#import <QuartzCore/QuartzCore.h>
#import <UIKit/UIKit.h>

@interface CALayer (BorderProperties)

// This assigns a CGColor to borderColor.
@property (nonatomic, assign) UIColor* borderUIColor;

@end

Implementation File:

#import "CALayer+BorderProperties.h"

@implementation CALayer (BorderProperties)

- (void)setBorderUIColor:(UIColor *)color {
    self.borderColor = color.CGColor;
}

- (UIColor *)borderUIColor {
    return [UIColor colorWithCGColor:self.borderColor];
}

@end

Swift 2.0:

extension CALayer {
var borderUIColor: UIColor {
    set {
        self.borderColor = newValue.CGColor
    }

    get {
        return UIColor(CGColor: self.borderColor!)
    }
}
}

And finally go to your storyboard/XIB, follow the remaining steps;

5. Click on the View object for which you want to set border Color.
6. Click on "Identity Inspector"(3rd from Left) in "Utility"(Right side of the screen) panel.
7. Under "User Defined Runtime Attributes", click on the "+" button to add a key path.
8. Set the type of the key path to "Color".
9. Enter the value for key path as "layer.borderUIColor". [Remember this should be the variable name you declared in category, not borderColor here it's borderUIColor].
10. Finally chose whatever color you want.

You've to set layer.borderWidth property value to at least 1 to see the border color.

Build and Run. Happy Coding. :)

Modified @Seth Ladd answer for who's prefer Swift style of singleton like .shared:

class Auth {
  // singleton
  static final Auth _singleton = Auth._internal();
  factory Auth() => _singleton;
  Auth._internal();
  static Auth get shared => _singleton;

  // variables
  String username;
  String password;
}

Sample:

Auth.shared.username = 'abc';

class Thing {  
    public int value;  

    public Thing (int x) {
        value = x;
    }

    equals (Thing x) {
        if (x.value == value) return true;
        return false;
    }
}

You must write:

class Thing {  
    public int value;  

    public Thing (int x) {
        value = x;
    }

    public boolean equals (Object o) {
    Thing x = (Thing) o;
        if (x.value == value) return true;
        return false;
    }
}

Now it works ;)

So my answer ended up being a solution that allows me to use the _this variable pointing to the original object. I create a new instance of a "Square" however I hated the way the "Square" generated it's size. I thought it should follow my specific needs. However in order to do so I needed the square to have an updated "GetSize" function with the internals of that function calling other functions already existing in the square such as this.height, this.GetVolume(). But in order to do so I needed to do this without any crazy hacks. So here is my solution.

Some other Object initializer or helper function.

this.viewer = new Autodesk.Viewing.Private.GuiViewer3D(
  this.viewerContainer)
var viewer = this.viewer;
viewer.updateToolbarButtons =  this.updateToolbarButtons(viewer);

Function in the other object.

updateToolbarButtons = function(viewer) {
  var _viewer = viewer;
  return function(width, height){ 
blah blah black sheep I can refer to this.anything();
}
};

$("div.test:not(:first)").hide();

or:

$("div.test:not(:eq(0))").hide();

or:

$("div.test").not(":eq(0)").hide();

or:

$("div.test:gt(0)").hide();

or: (as per @Jordan Lev's comment):

$("div.test").slice(1).hide();

and so on.

What about replace the item if you know the position:

aList[0]=2014

Or if you don't know the position loop in the list, find the item and then replace it

aList = [123, 'xyz', 'zara', 'abc']
    for i,item in enumerate(aList):
      if item==123:
        aList[i]=2014
        break
    
    print aList

I prefer the immutable version

foo = {
    1:1,
    2:2,
    3:3
}
removeKeys = [1,2]
def woKeys(dct, keyIter):
    return {
        k:v
        for k,v in dct.items() if k not in keyIter
    }

>>> print(woKeys(foo, removeKeys))
{3: 3}
>>> print(foo)
{1: 1, 2: 2, 3: 3}

Really, there isn't. there are about a half-zillion different regex syntaxes; they seem to come down to Perl, EMACS/GNU, and AT&T in general, but I'm always getting surprised too.

A cleaner way to handle file open/close and avoid memory leaks:

Prep:

import numpy as np
import h5py

data_to_write = np.random.random(size=(100,20)) # or some such

Write:

with h5py.File('name-of-file.h5', 'w') as hf:
    hf.create_dataset("name-of-dataset",  data=data_to_write)

Read:

with h5py.File('name-of-file.h5', 'r') as hf:
    data = hf['name-of-dataset'][:]

Path changes appear to be persistent if you set the SHELL variable in your makefile first:

SHELL := /bin/bash
PATH := bin:$(PATH)

test all:
    x

I don't know if this is desired behavior or not.

Try using the SQL_NO_CACHE (MySQL 5.7) option in your query. (MySQL 5.6 users click HERE )

eg.

SELECT SQL_NO_CACHE * FROM TABLE

This will stop MySQL caching the results, however be aware that other OS and disk caches may also impact performance. These are harder to get around.

you can do it like this:

<script>
    function SomeDeleteRowFunction(o) {
     //no clue what to put here?
     var p=o.parentNode.parentNode;
         p.parentNode.removeChild(p);
    }
    </script>

    <table>
       <tr>
           <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
       </tr>
       <tr>
           <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
       </tr>
       <tr>
           <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
       </tr>
    </table>

I had an issue with XCode 10.2 specifying the correct iOS simulator version number, so used:

react-native run-ios --simulator='iPhone X (com.apple.CoreSimulator.SimRuntime.iOS-12-1)'

Let's take look at what breakpoint() can do for you in 3.7+.

I have installed ipdb and pdbpp, which are both enhanced debuggers, via

pip install pdbpp
pip install ipdb

My test script, really doesn't do much, just calls breakpoint().

#test_188_breakpoint.py
myvars=dict(foo="bar")
print("before breakpoint()")
breakpoint()   # 
print(f"after breakpoint myvars={myvars}")

breakpoint() is linked to the PYTHONBREAKPOINT environment variable.

CASE 1: disabling breakpoint()

You can set the variable via bash as usual

export PYTHONBREAKPOINT=0

This turns off breakpoint() where it does nothing (as long as you haven't modified sys.breakpointhook() which is outside of the scope of this answer).

This is what a run of the program looks like:

(venv38) myuser@explore$ export PYTHONBREAKPOINT=0
(venv38) myuser@explore$ python test_188_breakpoint.py
before breakpoint()
after breakpoint myvars={'foo': 'bar'}
(venv38) myuser@explore$

Didn't stop, because I disabled breakpoint. Something that pdb.set_trace() can't do !

CASE 2: using the default pdb behavior:

Now, let's unset PYTHONBREAKPOINT which puts us back to normal, enabled-breakpoint behavior (it's only disabled when 0 not when empty).

(venv38) myuser@explore$ unset PYTHONBREAKPOINT
(venv38) myuser@explore$ python test_188_breakpoint.py
before breakpoint()
[0] > /Users/myuser/kds2/wk/explore/test_188_breakpoint.py(6)<module>()
-> print(f"after breakpoint myvars={myvars}")
(Pdb++) print("pdbpp replaces pdb because it was installed")
pdbpp replaces pdb because it was installed
(Pdb++) c
after breakpoint myvars={'foo': 'bar'}

It stopped, but I actually got pdbpp because it replaces pdb entirely while installed. If I unistalled pdbpp, I'd be back to normal pdb.

Note: a standard pdb.set_trace() would still get me pdbpp

CASE 3: calling a custom debugger

But let's call ipdb instead. This time, instead of setting the environment variable, we can use bash to set it only for this one command.

(venv38) myuser@explore$ PYTHONBREAKPOINT=ipdb.set_trace py test_188_breakpoint.py
before breakpoint()
> /Users/myuser/kds2/wk/explore/test_188_breakpoint.py(6)<module>()
      5 breakpoint()
----> 6 print(f"after breakpoint myvars={myvars}")
      7

ipdb> print("and now I invoked ipdb instead")
and now I invoked ipdb instead
ipdb> c
after breakpoint myvars={'foo': 'bar'}

Essentially, what it does, when looking at $PYTHONBREAKPOINT:

from ipdb import set_trace  # function imported on the right-most `.`
set_trace()

Again, much cleverer than a plain old pdb.set_trace()

in practice? I'd probably settle on a debugger.

Say I want ipdb always, I would:

• export it via .profile or similar.
• disable on a command by command basis, without modifying the normal value

Example (pytest and debuggers often make for unhappy couples):

(venv38) myuser@explore$ export PYTHONBREAKPOINT=ipdb.set_trace
(venv38) myuser@explore$ echo $PYTHONBREAKPOINT
ipdb.set_trace
(venv38) myuser@explore$ PYTHONBREAKPOINT=0 pytest test_188_breakpoint.py

================================== no tests ran in 0.03s ===================================
(venv38) myuser@explore$ echo $PYTHONBREAKPOINT

p.s.

I'm using bash under macos, any posix shell will behave substantially the same. Windows, either powershell or DOS, may have different capabilities, especially around PYTHONBREAKPOINT=<some value> <some command> to set a environment variable only for one command.

To access the elements in the array, use array notation: $product['prodname']

$product->prodname is object notation, which can only be used to access object attributes and methods.

One item is going to have many tags. And one tag will belong to many items. This implies to me that you'll quite possibly need an intermediary table to overcome the many-to-many obstacle.

Something like:

Table: Items
Columns: Item_ID, Item_Title, Content

Table: Tags
Columns: Tag_ID, Tag_Title

Table: Items_Tags
Columns: Item_ID, Tag_ID

It might be that your web app is very very popular and need de-normalizing down the road, but it's pointless muddying the waters too early.

As others have said, the style you're after is actually just the Mac OS checkbox style, so it will look radically different on other devices.

In fact both screenshots you linked show what checkboxes look like on Mac OS in Chrome, the grey one is shown at non-100% zoom levels.

You need to call the

$.parseJSON();

For example:

...
success: function(data){
       var json = $.parseJSON(data); // create an object with the key of the array
       alert(json.html); // where html is the key of array that you want, $response['html'] = "<a>something..</a>";
    },
    error: function(data){
       var json = $.parseJSON(data);
       alert(json.error);
    } ...

see this in http://api.jquery.com/jQuery.parseJSON/

if you still have the problem of slashes: search for security.magicquotes.disabling.php or: function.stripslashes.php

Note:

This answer here is for those who try to use $.ajax with the dataType property set to json and even that got the wrong response type. Defining the header('Content-type: application/json'); in the server may correct the problem, but if you are returning text/html or any other type, the $.ajax method should convert it to json. I make a test with older versions of jQuery and only after version 1.4.4 the $.ajax force to convert any content-type to the dataType passed. So if you have this problem, try to update your jQuery version.

In a normal situation, variables are bound by scoping rule: Local variables work only within the defined function. Closure is a way of breaking this rule temporarily for convenience.

def n_times(a_thing)
  return lambda{|n| a_thing * n}
end

in the above code, lambda(|n| a_thing * n} is the closure because a_thing is referred by the lambda (an anonymous function creator).

Now, if you put the resulting anonymous function in a function variable.

foo = n_times(4)

foo will break the normal scoping rule and start using 4 internally.

foo.call(3)

returns 12.

#  This program reads columns in a csv file
import csv
ifile = open('years.csv', "r")
reader = csv.reader(ifile)

# initialization and declaration of variables
rownum = 0
year = 0
dec = 0
jan = 0
total_years = 0`

for row in reader:
    if rownum == 0:
        header = row  #work with header row if you like
    else:
    colnum = 0
    for col in row:
        if colnum == 0:
            year = float(col)
        if colnum == 1:
            dec = float(col)
        if colnum == 2:
            jan = float(col)
        colnum += 1
    # end of if structure

# now we can process results
if rownum != 0:
    print(year, dec, jan)
    total_years = total_years + year
    print(total_years)

# time to go after the next row/bar
rownum += 1

ifile.close()

A bit late but nonetheless... You need to create and identify the csv file named "years.csv":

Year Dec Jan 1 50 60 2 25 50 3 30 30 4 40 20 5 10 10

Here's a reusable way of doing it (it's typescript but you can adapt it to js):

export function waitFor<T>(signal: Observable<any>) {
    return (source: Observable<T>) =>
        new Observable<T>(observer =>
            signal.pipe(first())
                .subscribe(_ =>
                    source.subscribe(observer)
                )
        );
}

and you can use it like any operator:

var two = someOtherObservable.pipe(waitFor(one), take(1));

It's basically an operator that defers the subscribe on the source observable until the signal observable emits the first event.

All modern terminal emulators use ANSI escape codes to show colours and other things.
Don't bother with libraries, the code is really simple.

More info is here.

Example in C:

#include <stdio.h>

#define ANSI_COLOR_RED     "\x1b[31m"

The ternary operator is just a shorthand for and if/else block. Your working code does not have an else condition, so is not suitable for this.

The following example will work:

echo empty($address['street2']) ? 'empty' : 'not empty';

You copy and paste the following code. It will display all the tables with Name and Created Date

SELECT object_name,created FROM user_objects
WHERE object_name LIKE  '%table_name%'
AND object_type = 'TABLE'; 

Note: Replace '%table_name%' with the table name you are looking for.

For me this error was happening on a fresh Eclipse Luna SR2 (4.4.2) install and when trying to add a Mercurial repository, I resolved after downgrading from Java 8 to Java 7.

The reason you are getting rejected is that your tag lost sync with the remote version. This is the same behaviour with branches.

sync with the tag from the remote via git pull --rebase <repo_url> +refs/tags/<TAG> and after you sync, you need to manage conflicts. If you have a diftool installed (ex. meld) git mergetool meld use it to sync remote and keep your changes.

The reason you're pulling with --rebase flag is that you want to put your work on top of the remote one so you could avoid other conflicts.

Also, what I don't understand is why would you delete the dev tag and re-create it??? Tags are used for specifying software versions or milestones. Example of git tags v0.1dev, v0.0.1alpha, v2.3-cr(cr - candidate release) and so on..

Another way you can solve this is issue a git reflog and go to the moment you pushed the dev tag on remote. Copy the commit id and git reset --mixed <commmit_id_from_reflog> this way you know your tag was in sync with the remote at the moment you pushed it and no conflicts will arise.

You probably have a log4j.properties file somewhere in the project. In that file you can configure which level of debug output you want. See this example:

log4j.rootLogger=info, console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

log4j.logger.com.example=debug

The first line sets the log level for the root logger to "info", i.e. only info, warn, error and fatal will be printed to the console (which is the appender defined a little below that).

The last line sets the logger for com.example.* (if you get your loggers via LogFactory.getLogger(getClass())) will be at debug level, i.e. debug will also be printed.

a = [0,1,2,3,127,200,255]
print str.join("", ("%02x" % i for i in a))

prints

000102037fc8ff

(Also note that your code will fail for integers in the range from 10 to 15.)

This question is old but here is another answer because it is useful fo others:

thread.sleep is not a good method for waiting, because usually it freezes the software until finishing its time, this function is better:

   Imports VB = Microsoft.VisualBasic

   Public Sub wait(ByVal seconds As Single)
     Static start As Single
     start = VB.Timer()
     Do While VB.Timer() < start + seconds
       System.Windows.Forms.Application.DoEvents()
     Loop
   End Sub

The above function waits for a specific time without freezing the software, however increases the CPU usage.

This function not only doesn't freeze the software, but also doesn't increase the CPU usage:

   Private Sub wait(ByVal seconds As Integer)
     For i As Integer = 0 To seconds * 100
       System.Threading.Thread.Sleep(10)
       Application.DoEvents()
     Next
   End Sub

library(lubridate) if your date format is like this '04/24/2017 05:35:00'then change it like below prods.all$Date2<-gsub("/","-",prods.all$Date2) then change the date format parse_date_time(prods.all$Date2, orders="mdy hms")

I try like this with function then calling if needed a this function. Has been worked for me.

function modal_fix() {
var a = $(".modal"),
    b = $("body");
a.on("shown.bs.modal", function () {
    b.hasClass("modal-open") || b.addClass("modal-open");
});
}

I had a similar problem. My data is provided by a remote server. I want some value to be entered in the selectize box, but it is not sure in advance whether this value is a valid one on the server.

So I want the value to be entered in the box, and I want selectize to show the possible options just if like the user had entered the value.

I ended up using this hack (which it is probably unsupported):

var $selectize = $("#my_input").selectize(/* settings with load*/);
var selectize = $select[0].selectize;
// get the search from the remote server
selectize.onSearchChange('my value');
// enter the input in the input field
$selectize.parent().find('input').val('my value');
// focus on the input field, to make the options visible
$selectize.parent().find('input').focus();

Most of the solutions given here to create the prepared query are more complex that they need to be. Using PHP's built in functions you can easily creare the SQL statement without significant overhead.

Given $records, an array of records where each record is itself an indexed array (in the form of field => value), the following function will insert the records into the given table $table, on a PDO connection $connection, using only a single prepared statement. Note that this is a PHP 5.6+ solution because of the use of argument unpacking in the call to array_push:

private function import(PDO $connection, $table, array $records)
{
    $fields = array_keys($records[0]);
    $placeHolders = substr(str_repeat(',?', count($fields)), 1);
    $values = [];
    foreach ($records as $record) {
        array_push($values, ...array_values($record));
    }

    $query = 'INSERT INTO ' . $table . ' (';
    $query .= implode(',', $fields);
    $query .= ') VALUES (';
    $query .= implode('),(', array_fill(0, count($records), $placeHolders));
    $query .= ')';

    $statement = $connection->prepare($query);
    $statement->execute($values);
}

The solution i found was

const [files, setFiles] = useState([] as any);

Check this out: http://qrdroid.com/web-masters.php

You can create a link in your web form, something like:

http://qrdroid.com/scan?q=http://www.your-site.com/your-form.php?code={CODE}

When somebody clicks that link, an app to scan the code will be opened. After the user scans the code, http://www.your-site.com/your-form.php?code={CODE} will be automatically called. You can then make your-form.php read the parameter code to prepopulate the field.

The is no API for adding a shortcut to the home screen in iOS, so no third-party browser is capable of providing that functionality.

The HttpRequest class represents the request made to the server and has various properties associated with it, such as QueryString.

The ASP.NET run-time parses a request to the server and populates this information for you.

Read HttpRequest Properties for a list of all the potential properties that get populated on you behalf by ASP.NET.

Note: not all properties will be populated, for instance if your request has no query string, then the QueryString will be null/empty. So you should check to see if what you expect to be in the query string is actually there before using it like this:

if (!String.IsNullOrEmpty(Request.QueryString["pID"]))
{
    // Query string value is there so now use it
    int thePID = Convert.ToInt32(Request.QueryString["pID"]);
}

To resolve all conflicts with the version in a particular branch:

git diff --name-only --diff-filter=U | xargs git checkout ${branchName}

So, if you are already in the merging state, and you want to keep the master version of the conflicting files:

git diff --name-only --diff-filter=U | xargs git checkout master

If you're using bootstrap 3 date time picker, try this:

$('.selector').datetimepicker({ maxDate: $.now() });

You could use the copy() function :

// Will copy foo/test.php to bar/test.php
// overwritting it if necessary
copy('foo/test.php', 'bar/test.php');

Quoting a couple of relevant sentences from its manual page :

Makes a copy of the file source to dest.

If the destination file already exists, it will be overwritten.

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

If you want to set a default button action in a JTextField enter, you have to do this:

//put this after initComponents();

textField.addActionListener(button.getActionListeners()[0]);

It is [0] because a button can has a lot of actions, but normally just has one (ActionPerformed).

DECLARE @records varchar(400)
SELECT @records = 'a,b,c,d'
select  LEN(@records) as 'Before removing Commas' , LEN(@records) - LEN(REPLACE(@records, ',', '')) 'After Removing Commans'

PHP 5.3 has functions to create and reformat at DateTime object from whatever format you specify:

$mysql_date = "2012-01-02";   // date in Y-m-d format as MySQL stores it
$date_obj = date_create_from_format('Y-m-d',$mysql_date);
$date = date_format($date_obj, 'm/d/Y');
echo $date;

Outputs:

01/02/2012

MySQL can also control the formatting by using the STR_TO_DATE() function when inserting/updating, and the DATE_FORMAT() when querying.

$php_date = "01/02/2012";
$update_query = "UPDATE `appointments` SET `start_time` = STR_TO_DATE('" . $php_date . "', '%m/%d/%Y')";
$query = "SELECT DATE_FORMAT(`start_time`,'%m/%d/%Y') AS `start_time` FROM `appointments`";

As noted, numpy.random.seed(0) sets the random seed to 0, so the pseudo random numbers you get from random will start from the same point. This can be good for debuging in some cases. HOWEVER, after some reading, this seems to be the wrong way to go at it, if you have threads because it is not thread safe.

from differences-between-numpy-random-and-random-random-in-python:

For numpy.random.seed(), the main difficulty is that it is not thread-safe - that is, it's not safe to use if you have many different threads of execution, because it's not guaranteed to work if two different threads are executing the function at the same time. If you're not using threads, and if you can reasonably expect that you won't need to rewrite your program this way in the future, numpy.random.seed() should be fine for testing purposes. If there's any reason to suspect that you may need threads in the future, it's much safer in the long run to do as suggested, and to make a local instance of the numpy.random.Random class. As far as I can tell, random.random.seed() is thread-safe (or at least, I haven't found any evidence to the contrary).

example of how to go about this:

from numpy.random import RandomState
prng = RandomState()
print prng.permutation(10)
prng = RandomState()
print prng.permutation(10)
prng = RandomState(42)
print prng.permutation(10)
prng = RandomState(42)
print prng.permutation(10)

may give:

[3 0 4 6 8 2 1 9 7 5]

[1 6 9 0 2 7 8 3 5 4]

[8 1 5 0 7 2 9 4 3 6]

[8 1 5 0 7 2 9 4 3 6]

Lastly, note that there might be cases where initializing to 0 (as opposed to a seed that has not all bits 0) may result to non-uniform distributions for some few first iterations because of the way xor works, but this depends on the algorithm, and is beyond my current worries and the scope of this question.

START has a peculiarity involving double quotes around the first parameter. If the first parameter has double quotes it uses that as the optional TITLE for the new window.

I believe what you want is:

start "" "c:\program files\Microsoft Virtual PC\Virtual PC.exe" -pc MY-PC -launch

In other words, give it an empty title before the name of the program to fake it out.

Stumbled upon this thread a couple years later. In 2016, most Android devices will have API level >= 18 and should thus rely on Location.isFromMockProvider() as pointed out by Fernando.

I extensively experimented with fake/mock locations on different Android devices and distros. Unfortunately .isFromMockProvider() is not 100% reliable. Every once in a while, a fake location will not be labeled as mock. This seems to be due to some erroneous internal fusion logic in the Google Location API.

I wrote a detailed blog post about this, if you want to learn more. To summarize, if you subscribe to location updates from the Location API, then switch on a fake GPS app and print the result of each Location.toString() to the console, you will see something like this:

Notice how, in the stream of location updates, one location has the same coordinates as the others, but is not flagged as a mock and has a much poorer location accuracy.

To remedy this problem, I wrote a utility class that will reliably suppress Mock locations across all modern Android versions (API level 15 and up):

LocationAssistant - Hassle-free location updates on Android

Basically, it "distrusts" non-mock locations that are within 1km of the last known mock location and also labels them as a mock. It does this until a significant number of non-mock locations have arrived. The LocationAssistant can not only reject mock locations, but also unburdens you from most of the hassle of setting up and subscribing to location updates.

To receive only real location updates (i.e. suppress mocks), use it as follows:

public class MyActivity extends Activity implements LocationAssistant.Listener {

    private LocationAssistant assistant;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ...
        // You can specify a different accuracy and interval here.
        // The last parameter (allowMockLocations) must be 'false' to suppress mock locations.  
        assistant = new LocationAssistant(this, this, LocationAssistant.Accuracy.HIGH, 5000, false);
    }

    @Override
    protected void onResume() {
        super.onResume();
        assistant.start();
    }

    @Override
    protected void onPause() {
        assistant.stop();
        super.onPause();
    }

    @Override
    public void onNewLocationAvailable(Location location) {
        // No mock locations arriving here
    }

    ...
}

onNewLocationAvailable() will now only be invoked with real location info. There are some more listener methods you need to implement, but in the context of your question (how to prevent GPS spoofing) this is basically it.

Of course, with a rooted OS you can still find ways of spoofing location info that are impossible for normal apps to detect.

Make use of Arrow functions it improves the readability of code. No need to return anything in API.fetchComments, Api call is asynchronous when the request is completed then will get the response, there you have to just dispatch type and data.

Below code does the same job by making use of Arrow functions.

export const bindComments = postId => {
  return dispatch => {
    API.fetchComments(postId).then(comments => {
      dispatch({
        type: BIND_COMMENTS,
        comments,
        postId
      });
    });
  };
};

Check your Entity class. Use String instead of Long and float instead of double .

It's probably worth noting that Powershell v3 and up, contains a cmdlet called Invoke-WebRequest that has some curl-ish capabilities. The New-WebServiceProxy and Invoke-RestMethod cmdlets are probably worth mentioning too.

I'm not sure they will fit your needs or not, but although I'm not a Windows guy, I have to say I find the object approach PS takes, a lot easier to work with than utilities such as curl, wget etc. They may be worth taking a look at

This happened to me as well. For me, Postfix was located at the same server as the PHP script, and the error was happening when I would be using SMTP authentication and smtp.domain.com instead of localhost.

So when I commented out these lines:

$mail->SMTPAuth = true;
$mail->SMTPSecure = "tls";

and set the host to

$mail->Host = "localhost";

instead

$mail->Host = 'smtp.mydomainiuse.com'

and it worked :)

To perform case-insensitive operations, supply re.IGNORECASE

>>> import re
>>> test = 'UPPER TEXT, lower text, Mixed Text'
>>> re.findall('text', test, flags=re.IGNORECASE)
['TEXT', 'text', 'Text']

and if we want to replace text matching the case...

>>> def matchcase(word):
        def replace(m):
            text = m.group()
            if text.isupper():
                return word.upper()
            elif text.islower():
                return word.lower()
            elif text[0].isupper():
                return word.capitalize()
            else:
                return word
        return replace

>>> re.sub('text', matchcase('word'), test, flags=re.IGNORECASE)
'UPPER WORD, lower word, Mixed Word'

A new answer that uses dplyr and tidyr:

Extracts the desired column names and converts to a list

library(tidyverse)

col_names <- raw_dta %>% 
  slice(2) %>%
  pivot_longer(
    cols = "X2":"X10", # until last named column
    names_to = "old_names",
    values_to = "new_names") %>% 
  pull(new_names)

Removes the incorrect rows and adds the correct column names

dta <- raw_dta %>% 
  slice(-1, -2) %>% # Removes the rows containing new and original names
  set_names(., nm = col_names)

Here is a nice article (the same one @Ken posted) on how to polish up Jpuyter (the new IPython) notebooks for presentation. There are countless ways to extend Jupyter using JS, HTML, and CSS, including the ability to communicate with the notebook's python kernel from javascript. There are magic decorators for %%HTML and %%javascript so you can just do something like this in a cell by itself:

%%HTML
<script>
  function code_toggle() {
    if (code_shown){
      $('div.input').hide('500');
      $('#toggleButton').val('Show Code')
    } else {
      $('div.input').show('500');
      $('#toggleButton').val('Hide Code')
    }
    code_shown = !code_shown
  }

  $( document ).ready(function(){
    code_shown=false;
    $('div.input').hide()
  });
</script>
<form action="javascript:code_toggle()"><input type="submit" id="toggleButton" value="Show Code"></form>

I can also vouch Chris's methods work in jupyter 4.X.X.

Depending on your application, you may want to consider using System.nanoTime() instead.

For Bootstrap v4.3.1. Try below:

$(document).ready(function() {
    var pathname = window.location.pathname; //get the path of current page
    $('.navbar-nav > li > a[href="'+pathname+'"]').parent().addClass('active');
})

In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as

save page as  
filename     : any_name.html 
save as type : webpage complete.

Then you will get any_name.html and any_name folder.

You have a scalar valued function as opposed to a table valued function. The from clause is used for tables. Just query the value directly in the column list.

select dbo.fun_functional_score('01091400003')

For ES2016, spread operator for objects. Note: This is after ES6 and so transpiler will need to be adjusted.

const arr = ['a', 'b', 'c'];_x000D_
const obj = {...arr}; // -> {0: "a", 1: "b", 2: "c"} 

If you want to avoid the problem that David Meister posted and you are sure about the number of decimal places, you can replace all dots and commas and divide by 100, ex.:

var value = "2,299.00";
var amount = parseFloat(value.replace(/"|\,|\./g, ''))/100;

or if you have 3 decimals

var value = "2,299.001";
var amount = parseFloat(value.replace(/"|\,|\./g, ''))/1000;

It's up to you if you want to use parseInt, parseFloat or Number. Also If you want to keep the number of decimal places you can use the function .toFixed(...).

big=small=values[0]; //assigns element to be highest or lowest value

Should be AFTER fill loop

//counts to 20 and prompts user for value and stores it
for ( int i = 0; i < 20; i++ )
{
    cout << "Enter value " << i << ": ";
    cin >> values[i];
}
big=small=values[0]; //assigns element to be highest or lowest value

since when you declare array - it's unintialized (store some undefined values) and so, your big and small after assigning would store undefined values too.

And of course, you can use std::min_element, std::max_element, or std::minmax_element from C++11, instead of writing your loops.

same issue after removing properties from a schema after first building some indexes on saving. removing property from schema leads to an null value for a non existing property, that still had an index. dropping index or starting with a new collection from scratch helps here.

note: the error message will lead you in that case. it has a path, that does not exist anymore. im my case the old path was ...$uuid_1 (this is an index!), but the new one is ....*priv.uuid_1

I had the same issue, but mine was because of wrong casing in path:

// Wrong - uppercase C in /pathCoordinate/
./path/pathCoordinate/pathCoordinateForm.component

// Correct - lowercase c in /pathcoordinate/
./path/pathcoordinate/pathCoordinateForm.component

The else clause is executed if you exit a block normally, by hitting the loop condition or falling off the bottom of a try block. It is not executed if you break or return out of a block, or raise an exception. It works for not only while and for loops, but also try blocks.

You typically find it in places where normally you would exit a loop early, and running off the end of the loop is an unexpected/unusual occasion. For example, if you're looping through a list looking for a value:

for value in values:
    if value == 5:
        print "Found it!"
        break
else:
    print "Nowhere to be found. :-("

I like the WMIC and TASKLIST tools but they are not available in home/basic editions of windows.Another way is to use QPROCESS command available on almost every windows machine (for the ones that have terminal services - I think only win XP without SP2 , so practialy every windows machine):

@echo off
:check_process
setlocal
if "%~1" equ "" echo pass the process name as forst argument && exit /b 1
:: first argument is the process you want to check if running
set process_to_check=%~1
:: QPROCESS can display only the first 12 symbols of the running process
:: If other tool is used the line bellow could be deleted
set process_to_check=%process_to_check:~0,12%

QPROCESS * | find /i "%process_to_check%" >nul 2>&1 && (
    echo process %process_to_check%  is running
) || (
    echo process %process_to_check%  is not running
)
endlocal

QPROCESS command is not so powerful as TASKLIST and is limited in showing only 12 symbols of process name but should be taken into consideration if TASKLIST is not available.

More simple usage where it uses the name if the process as an argument (the .exe suffix is mandatory in this case where you pass the executable name):

@echo off
:check_process
setlocal
if "%~1" equ "" echo pass the process name as forst argument && exit /b 1
:: first argument is the process you want to check if running
:: .exe suffix is mandatory
set "process_to_check=%~1"


QPROCESS "%process_to_check%" >nul 2>&1 && (
    echo process %process_to_check%  is running
) || (
    echo process %process_to_check%  is not running
)
endlocal

The difference between two ways of QPROCESS usage is that the QPROCESS * will list all processes while QPROCESS some.exe will filter only the processes for the current user.

Using WMI objects through windows script host exe instead of WMIC is also an option.It should on run also on every windows machine (excluding the ones where the WSH is turned off but this is a rare case).Here bat file that lists all processes through WMI classes and can be used instead of QPROCESS in the script above (it is a jscript/bat hybrid and should be saved as .bat):

@if (@X)==(@Y) @end /* JSCRIPT COMMENT **


@echo off
cscript //E:JScript //nologo "%~f0"
exit /b

************** end of JSCRIPT COMMENT **/


var winmgmts = GetObject("winmgmts:\\\\.\\root\\cimv2");
var colProcess = winmgmts.ExecQuery("Select * from Win32_Process");
var processes =  new Enumerator(colProcess);
for (;!processes.atEnd();processes.moveNext()) {
    var process=processes.item();
    WScript.Echo( process.processID + "   " + process.Name );
}

And a modification that will check if a process is running:

@if (@X)==(@Y) @end /* JSCRIPT COMMENT **


@echo off
if "%~1" equ "" echo pass the process name as forst argument && exit /b 1
:: first argument is the process you want to check if running
set process_to_check=%~1

)

    WScript.Echo( process.processID + "   " + process.Name );
}

The two options could be used on machines that have no TASKLIST.

The ultimate technique is using MSHTA . This will run on every windows machine from XP and above and does not depend on windows script host settings. the call of MSHTA could reduce a little bit the performance though (again should be saved as bat):

If you want to maintain a sorted list which you will frequently modify (i.e. a structure which, in addition to being sorted, allows duplicates and whose elements can be efficiently referenced by index), then use an ArrayList but when you need to insert an element, always use Collections.binarySearch() to determine the index at which you add a given element. The latter method tells you the index you need to insert at to keep your list in sorted order.

There's an easy way to produce this error:

    $joe = null;
    $joe->anything();

Will render the error:

Fatal error: Call to a member function anything() on a non-object in /Applications/XAMPP/xamppfiles/htdocs/casMail/dao/server.php on line 23

It would be a lot better if PHP would just say,

Fatal error: Call from Joe is not defined because (a) joe is null or (b) joe does not define anything() in on line <##>.

Usually you have build your class so that $joe is not defined in the constructor or

As devio says there is no way to simply edit a UDT if it's in use.

A work-round through SMS that worked for me was to generate a create script and make the appropriate changes; rename the existing UDT; run the create script; recompile the related sprocs and drop the renamed version.

Bubbling

  Event propagate to the upto root element is **BUBBLING**.

Capturing

  Event propagate from body(root) element to eventTriggered Element is **CAPTURING**.

what language is this? If you're using a language that passes everything by reference like Java (except for native types), typically you can call .clone() method. The .clone() method is typically implemented by copying/cloning all relevant instance fields into the new object.

Ok, solved my problem, if anyone is passing by here is the answer:

Just had to add left: 0, and top: 0, to the styles, and yes, I'm tired.

position: 'absolute',
left:     0,
top:      0,

You can use that and adjust the time you want to launch 1= onload 2000= 2 sec

$(document).ready(function(){
 $('#click').click(function(){
        alert('button clicked');
    });
  // set time out 2 sec
     setTimeout(function(){
        $('#click').trigger('click');
    }, 2000);
});

When you do throw ex, that thrown exception becomes the "original" one. So all previous stack trace will not be there.

If you do throw, the exception just goes down the line and you'll get the full stack trace.

newTitle is a local variable where you create the fields. So when that functions ends, the variable newTitle, does not exist anymore. (The JTextField that was referenced by newTitle does still exist however.)

Thus, increase the scope of the variable, so that you can access it another method.

public SomeFrame extends JFrame {
   JTextField myTitle;//can be used anywhere in this class

   creationOfTheFields()
   {
   //other code
      myTitle = new JTextField("spam");  
      myTitle.setBounds(80, 40, 225, 20);
      options.add(myTitle);
   //blabla other code
   }

   private void New_Name()  
   {  
      this.setTitle(myTitle.getText());  
   } 
}

You must check this: Docblock Comment standards

http://pear.php.net/manual/en/standards.sample.php

In case you want to always activate the latest C++ standard, here's my extension of David Grayson's answer, in light of the recent (CMake 3.8 and CMake 3.11) additions of values of 17 and 20 for CMAKE_CXX_STANDARD):

IF (CMAKE_VERSION VERSION_LESS "3.8")
    SET(CMAKE_CXX_STANDARD 14)
ELSEIF (CMAKE_VERSION VERSION_LESS "3.11")
    SET(CMAKE_CXX_STANDARD 17)
ELSE()
    SET(CMAKE_CXX_STANDARD 20)
ENDIF()

# Typically, you'll also want to turn off compiler-specific extensions:
SET(CMAKE_CXX_EXTENSIONS OFF)

(Use that code in the place of set (CMAKE_CXX_STANDARD 11) in the linked answer.)

Having used Mono, I would NOT recommend it. The Mono runtime is bundled with your app, so your apk ends up being bloated at more than 6MB. A better programming solution for C# would be dot42. Both Mono and dot42 are licensed products.

Personally, I would recommend using Java with the IntelliJ IDEA dev environment. I say this for 3 reasons:

1. There is so much Java code out there for Android already; do yourself a favour and don't re-invent the wheel.
2. IDEA is similar enough to Visual Studio as to be a cinch to learn; it is made by JetBrains and the intelli-sense is better than VS.
3. IDEA is free.

I have been a C# programmer for 12 years and started developing for Android with C# but ended up jumping ship and going the Java route. The languages are so similar you really won't notice much of a learning curve.

P.S. If you want to use LINQ, serialization and other handy features that are native to C# then you just need to look for the equivalent java library.

One way to resolve this would be to first add your user to the docker group by running the following

sudo usermod -aG docker $USER

IMPORTANT: Remember to log out of your system (not just your terminal) and back in for this to take effect!

I'd say like letiagoalves said, but you might have more than one checkbox question in your form, so I'd recommend to do like this:

  var limit = 3;
    $('input.single-checkbox').on('change', function(evt) {
        if($('input.single-checkbox').siblings('input.single-checkbox:checked').length > limit) {
            this.checked = false;
        }
    });

You have to loop through all rows, and add the missing rows and columns. For the already existing rows, you loop from c to cols, for the new rows, first push an empty array to outer array, then loop from 0 to cols:

var r = 3; //start from rows 3
var c = 5; //start from col 5

var rows = 8;
var cols = 7;

for (var i = 0; i < rows; i++) {
  var start;
  if (i < r) {
    start =  c;
  } else {
    start = 0;
    myArray.push([]);
  }
  for (var j = start; j < cols; j++) {
        myArray[i].push(0);
    }
}

Well, when writing it out to file, you do know what class T is, so you can store that in dump. Then, when reading it back in, you can dynamically call it using reflection.

public JSONObject dump() throws JSONException {
    JSONObject result = new JSONObject();
    JSONArray a = new JSONArray();
    for(T i : items){
        a.put(i.dump());
        // inside this i.dump(), store "class-name"
    }
    result.put("items", a);
    return result;
}

public void load(JSONObject obj) throws JSONException {
    JSONArray arrayItems = obj.getJSONArray("items");
    for (int i = 0; i < arrayItems.length(); i++) {
        JSONObject item = arrayItems.getJSONObject(i);
        String className = item.getString("class-name");
        try {
            Class<?> clazzy = Class.forName(className);
            T newItem = (T) clazzy.newInstance();
            newItem.load(obj);
            items.add(newItem);
        } catch (InstantiationException e) {
            // whatever
        } catch (IllegalAccessException e) {
            // whatever
        } catch (ClassNotFoundException e) {
            // whatever
        }
    }

This somewhat depends on what platform you are on. The most common way to do this is by printing ANSI escape sequences. For a simple example, here's some python code from the blender build scripts:

// This is a object for use ANSI escape to color the text in the terminal
const bColors = {
    HEADER    : '\033[95m',
    OKBLUE    : '\033[94m',
    OKGREEN   : '\033[92m',
    WARNING   : '\033[93m',
    FAIL      : '\033[91m',
    ENDC      : '\033[0m', 
    BOLD      : '\033[1m',   
    UNDERLINE : '\033[4m'
}

To use code like this, you can do something like

console.log(`${bColors.WARNING} My name is sami ${bColors.ENDC}`)

I'd make a comparator using Guava's ComparisonChain:

public class ReportComparator implements Comparator<Report> {
  public int compare(Report r1, Report r2) {
    return ComparisonChain.start()
        .compare(r1.getReportKey(), r2.getReportKey())
        .compare(r1.getStudentNumber(), r2.getStudentNumber())
        .compare(r1.getSchool(), r2.getSchool())
        .result();
  }
}

If you have installed SQL 2005 express edition and want to install BIDS (Business Intelligence Development Studio) then go to here Microsoft SQL Server 2005 Express Edition Toolkit

This has an option to install BIDS on my machine, and is the only way l could get hold of BIDS for SQL Server 2005 express edition.

Also this package l think has also allowed me to install both BIDS 2005 & 2008 express edition on the same machine.

execute

show VARIABLES like "%char%”;

find character-set-server if is not utf8mb4.

set it in your my.cnf, like

vim /etc/my.cnf

add one line

character_set_server = utf8mb4

at last restart mysql

Note that starting Python 3.8, and the introduction of assignment expressions (PEP 572) (:= operator), it's possible to improve a bit on Krzysztof Krason's solution by capturing the match result directly within the if condition as a variable and re-use it in the condition's body:

# pattern = '<title>(.*)</title>'
# text = '<title>hello</title>'
if match := re.search(pattern, text, re.IGNORECASE):
  title = match.group(1)
# hello

Here's an updated python version to search google and get all results href's:

import urllib.parse
import re
from selenium import webdriver
driver.get("https://google.com/")
q = driver.find_element_by_name('q')
q.send_keys("always look on the bright side of life monty python")
q.submit();
sleep(1)
links= driver.find_elements_by_xpath("//h3[@class='r']//a")
for link in links:
    url = urllib.parse.unquote(webElement.get_attribute("href")) # decode the url
    url = re.sub("^.*?(?:url\?q=)(.*?)&sa.*", r"\1", url, 0, re.IGNORECASE) # get the clean url

Please note that the element id/name/class (@class='r') ** will change depending on the user agent**.
The above code used PhantomJS default user agent.

In eclipse:

You may have to drag the DDMS window down. 'Location Controls' is located under 'Telephony Actions' and may be hidden by a normally sized console view ( the bar with console, LogCat etc may be covering it!)

Check you are including all the source files within your solution that you are referencing.

If you are not including the source file (and thus the implementation) for the class Field in your project it won't be built and you will be unable to link during compilation.

Alternatively, perhaps you are using a static or dynamic library and have forgotten to tell the linker about the .libs?

-fix- because you want to change from radians to degrees, it is actually rad=deg * math.pi /180 and not deg*180/math.pi

import math
x=1                # in deg
x = x*math.pi/180  # convert to rad
y = math.cos(x)    # calculate in rad

print y

in 1 line it can be like this

y=math.cos(1*math.pi/180)

I was having issues because I updated my AdHoc provisioning profile with some new devices for use on TestFlight. Assumedly this is happening because Xcode has an old reference to your provisioning profile in either the codesigning build settings for the project or the targets. The way I fixed mine was to:

1. Go to both target build settings and project build settings, Under code signing change all the provisioning profiles to something else.
2. Go to devices/provisioning profiles in the Organizer delete the offending profiles, then click the refresh button in the bottom right.
3. Go back to to the target and project build settings and set your provisioning profiles to the appropriate (hopefully) newly refreshed provisioning profiles.
