The simple answer:

• doing a MOV RBX, 3 and MUL RBX is expensive; just ADD RBX, RBX twice

• ADD 1 is probably faster than INC here

• MOV 2 and DIV is very expensive; just shift right

• 64-bit code is usually noticeably slower than 32-bit code and the alignment issues are more complicated; with small programs like this you have to pack them so you are doing parallel computation to have any chance of being faster than 32-bit code

If you generate the assembly listing for your C++ program, you can see how it differs from your assembly.

Try this:

// convert from bitmap to byte array
public byte[] getBytesFromBitmap(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70, stream);
    return stream.toByteArray();
}

// get the base 64 string
String imgString = Base64.encodeToString(getBytesFromBitmap(someImg), 
                       Base64.NO_WRAP);

if (chapeau) {

You forgot the ending brace to this if statement, so the subsequent else if is considered a syntax error. You need to add the brace when the if statement body is complete:

if (chapeau) {
    cout << "le Professeur Violet";
}
else if (moustaches) {
    cout << "le Colonel Moutarde";
}
// ...

I guess this is also possible like this?

var movies = _db.Movies.TakeWhile(p => p.Genres.Any(x => listOfGenres.Contains(x));

Is "TakeWhile" worse than "Where" in sense of performance or clarity?

printf("%.<number>f", myFloat) //where <number> - digit after comma

http://www.cplusplus.com/reference/clibrary/cstdio/printf/

I think a more canonical way to do this is via:

command --feature

and

command --no-feature

argparse supports this version nicely:

parser.add_argument('--feature', dest='feature', action='store_true')
parser.add_argument('--no-feature', dest='feature', action='store_false')
parser.set_defaults(feature=True)

Of course, if you really want the --arg <True|False> version, you could pass ast.literal_eval as the "type", or a user defined function ...

def t_or_f(arg):
    ua = str(arg).upper()
    if 'TRUE'.startswith(ua):
       return True
    elif 'FALSE'.startswith(ua):
       return False
    else:
       pass  #error condition maybe?

If you are using an array (and purely an array), the lookup of "contains" is O(N), because worst case, you must iterate the entire array. Now if the array is sorted you can use a binary search, which reduces the search time to log(N) with the overhead of the sort.

If this is something that is invoked repeatedly, place it in a function:

private boolean inArray(int[] array, int value)
{  
     for (int i = 0; i < array.length; i++)
     {
        if (array[i] == value) 
        {
            return true;
        }
     }
    return false;  
}  

$.ajax(
{
    type: 'post',
    url: 'mail.php',
    data: form.serialize(),
    beforeSend: function()
    {
        $('.content').html('loading...');
    },
    success: function(data)
    {
        $('.content').html(data);
    },
    error: function()
    {
        $('.content').html('error');
    }
});

have fun playing arround!

if you should have quick loading times which prevent te loading showing, you can add a timeout of some sort.

If you think the performance of the query will be better using the index, how could you force the query to use the index?

First you would of course verify that the index gave a better result for returning the complete data set, right?

The index hint is the key here, but the more up to date way of specifying it is with the column naming method rather than the index naming method. In your case you would use:

select /*+ index(table_name (column_having_index)) */ *
from   table_name
where  column_having_index="some value"; 

In more complex cases you might ...

select /*+ index(t (t.column_having_index)) */ *
from   my_owner.table_name t,
       ...
where  t.column_having_index="some value"; 

With regard to composite indexes, I'm not sure that you need to specify all columns, but it seems like a good idea. See the docs here http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements006.htm#autoId18 on multiple index_specs and use of index_combine for multiple indexes, and here http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements006.htm#BABGFHCH for the specification of multiple columns in the index_spec.

According to the official site. These are the two ways

<div>
  {/* Comment goes here */}
  Hello, {name}!
</div>

Second Example:

<div>
    {/* It also works 
    for multi-line comments. */}
    Hello, {name}! 
</div>

Here is the link: https://reactjs.org/docs/faq-build.html#how-can-i-write-comments-in-jsx

Why nobody mentions matchMedia?

if (window.matchMedia("(min-width: 400px)").matches) {
  /* the viewport is at least 400 pixels wide */
} else {
  /* the viewport is less than 400 pixels wide */
}

Did not test that much, but tested with android default and android chrome browsers, desktop chrome, so far it looks like it works well.

Of course it does not return number value, but returns boolean - if matches or not, so might not exactly fit the question but that's what we want anyway and probably the author of question wants.

So they could be used one day if the language designers felt the need.

Also, if programmers from languages that do have these keywords (eg. C, C++) use them by mistake, then the Java compiler can give a useful error message.

Or maybe it was just to stop programmers using goto :)

I made use of sendkeys in shell scripting using a vbsscript file. Below is the code in vbs file,

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.SendKeys "C:\Demo.txt"
WshShell.SendKeys "{ENTER}"

Below is the selenium code line to run this vbs file,

driver.findElement(By.id("uploadname1")).click();
Thread.sleep(1000);
Runtime.getRuntime().exec( "wscript C:/script.vbs" );

A given ID can be only used once in a page. It's invalid HTML to have multiple objects with the same ID, even if they are in different parts of the page.

You could change your HTML to this:

<div id="div1" >
    <input type="text" class="edit1" />
    <input type="text" class="edit2" />
</div>
<div id="div2" >
    <input type="text" class="edit1" />
    <input type="text" class="edit2" />
</div>

Then, you could get the first item in div1 with a CSS selector like this:

#div1 .edit1

On in jQuery:

$("#div1 .edit1")

Or, if you want to iterate the items in one of your divs, you can do it like this:

$("#div1 input").each(function(index) {
    // do something with one of the input objects
});

If I couldn't use a framework like jQuery or YUI, I'd go get Sizzle and include that for it's selector logic (it's the same selector engine as is inside of jQuery) because DOM manipulation is massively easier with a good selector library.

If I couldn't use even Sizzle (which would be a massive drop in developer productivity), you could use plain DOM functions to traverse the children of a given element.

You would use DOM functions like childNodes or firstChild and nextSibling and you'd have to check the nodeType to make sure you only got the kind of elements you wanted. I never write code that way because it's so much less productive than using a selector library.

Working on Mac I followed the answer of Sean Patrick Floyd placing a settings.xml like above in my user folder /Users/user/.m2/

But this did not help. So I opened a Terminal and did a ls -la on the folder. This was showing

-rw-r--r--@

thus staff and everone can at least read the file. So I wondered if the message isn't wrong and if the real cause is the lack of write permissions. I set the file to:

-rw-r--rw-@

This did it. The message disappeared.

Android has all the tools you need to parse json built-in. Example follows, no need for GSON or anything like that.

Get your JSON:

Assume you have a json string

String result = "{\"someKey\":\"someValue\"}";

Create a JSONObject:

JSONObject jObject = new JSONObject(result);

If your json string is an array, e.g.:

String result = "[{\"someKey\":\"someValue\"}]"

then you should use JSONArray as demonstrated below and not JSONObject

To get a specific string

String aJsonString = jObject.getString("STRINGNAME");

To get a specific boolean

boolean aJsonBoolean = jObject.getBoolean("BOOLEANNAME");

To get a specific integer

int aJsonInteger = jObject.getInt("INTEGERNAME");

To get a specific long

long aJsonLong = jObject.getLong("LONGNAME");

To get a specific double

double aJsonDouble = jObject.getDouble("DOUBLENAME");

To get a specific JSONArray:

JSONArray jArray = jObject.getJSONArray("ARRAYNAME");

To get the items from the array

for (int i=0; i < jArray.length(); i++)
{
    try {
        JSONObject oneObject = jArray.getJSONObject(i);
        // Pulling items from the array
        String oneObjectsItem = oneObject.getString("STRINGNAMEinTHEarray");
        String oneObjectsItem2 = oneObject.getString("anotherSTRINGNAMEINtheARRAY");
    } catch (JSONException e) {
        // Oops
    }
}

When you use laravel modules, you may add the name's module:

@include('cimple::shared.posts_list')

NPM commands to update or fix vulnerabilities in some dependency manifest files

• Use below command to check outdated or vulnerabilities in your node modules.

  npm audit

• If any vulnerabilities found, use below command to fix all issues.

  npm audit fix

• If it doesn't work for you then try

  npm audit fix -f, this command will almost fix all vulnerabilities. Some dependencies or devDependencies are locked in package-lock.json file, so we use -f flag to force update them.

• If you don't want to use force audit fix then you can manually fix your dependencies versions by changing them in package-lock.json and package.json file. Then run

npm update && npm upgrade

That data:image/png;base64 URL is cool, I’ve never run into it before. The long encrypted link is the actual image, i.e. no image call to the server. See RFC 2397 for details.

Side note: I have had trouble getting larger base64 images to render on IE8. I believe IE8 has a 32K limit that can be problematic for larger files. See this other StackOverflow thread for details.

please modify your router.module.ts as:

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [
        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree',
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        },
        {
           path: '',
           redirectTo: 'two',
           pathMatch: 'full'
        }
    ]
},];

and in your component1.html

<h3>In One</h3>

<nav>
    <a routerLink="/two" class="dash-item">...Go to Two...</a>
    <a routerLink="/two/three" class="dash-item">... Go to THREE...</a>
    <a routerLink="/two/four" class="dash-item">...Go to FOUR...</a>
</nav>

<router-outlet></router-outlet>                   // Successfully loaded component2.html
<router-outlet name="nameThree" ></router-outlet> // Error: Cannot match any routes. URL Segment: 'three'
<router-outlet name="nameFour" ></router-outlet>  // Error: Cannot match any routes. URL Segment: 'three'

Sometimes you won't need that other half of the list. For example:

import sys
from itertools import ifilter

trustedPeople = sys.argv[1].split(',')
newName = sys.argv[2]

myFriends = ifilter(lambda x: x.startswith('Shi'), trustedPeople)

print '%s is %smy friend.' % (newName, newName not in myFriends 'not ' or '')

Your code is drawing the center of the baseline of the text, at the center of the view. In order to center the text at some point, x, y, you need to calculate the center of the text, and put that at the point.

This method will draw text centered at the point x, y. If you pass it the center of your view, it will draw the text centered.

private void drawTextCentered(String text, int x, int y, Paint paint, Canvas canvas) {
    int xPos = x - (int)(paint.measureText(text)/2);
    int yPos = (int) (y - ((textPaint.descent() + textPaint.ascent()) / 2)) ;

    canvas.drawText(text, xPos, yPos, textPaint);
}

Try:

android:layout_height="wrap_content"
android:scaleType="fitStart"

on the image in the RelativeLayout

If your start and end datetimes are on different days use TIMEDIFF.

SELECT TIMEDIFF(datetime1,datetime2)

if datetime1 > datetime2 then

SELECT TIMEDIFF("2019-02-20 23:46:00","2019-02-19 23:45:00")

gives: 24:01:00

and datetime1 < datetime2

SELECT TIMEDIFF("2019-02-19 23:45:00","2019-02-20 23:46:00")

gives: -24:01:00

If all you want to do is get rid of invalid hostname errors you can just do:

HttpClient httpClient = new DefaultHttpClient();
SSLSocketFactory sf = (SSLSocketFactory)httpClient.getConnectionManager()
    .getSchemeRegistry().getScheme("https").getSocketFactory();
sf.setHostnameVerifier(new AllowAllHostnameVerifier());

Angular 2 with Webpack (without CLI setup)

1- The tutorial by the Angular2 team

The Angular2 team published a tutorial for using Webpack

I created and placed the files from the tutorial in a small GitHub seed project. So you can quickly try the workflow.

Instructions:

• npm install

• npm start. For development. This will create a virtual "dist" folder that will be livereloaded at your localhost address.

• npm run build. For production. "This will create a physical "dist" folder version than can be sent to a webserver. The dist folder is 7.8MB but only 234KB is actually required to load the page in a web browser.
  
  

2 - A Webkit starter kit

This Webpack Starter Kit offers some more testing features than the above tutorial and seem quite popular.

Its work for all external devices, But make sure only get external device folder name and then you need to get file from given location using File class.

public static List<String> getExternalMounts() {
        final List<String> out = new ArrayList<>();
        String reg = "(?i).*vold.*(vfat|ntfs|exfat|fat32|ext3|ext4).*rw.*";
        String s = "";
        try {
            final Process process = new ProcessBuilder().command("mount")
                    .redirectErrorStream(true).start();
            process.waitFor();
            final InputStream is = process.getInputStream();
            final byte[] buffer = new byte[1024];
            while (is.read(buffer) != -1) {
                s = s + new String(buffer);
            }
            is.close();
        } catch (final Exception e) {
            e.printStackTrace();
        }

        // parse output
        final String[] lines = s.split("\n");
        for (String line : lines) {
            if (!line.toLowerCase(Locale.US).contains("asec")) {
                if (line.matches(reg)) {
                    String[] parts = line.split(" ");
                    for (String part : parts) {
                        if (part.startsWith("/"))
                            if (!part.toLowerCase(Locale.US).contains("vold"))
                                out.add(part);
                    }
                }
            }
        }
        return out;
    }

Calling:

List<String> list=getExternalMounts();
        if(list.size()>0)
        {
            String[] arr=list.get(0).split("/");
            int size=0;
            if(arr!=null && arr.length>0) {
                size= arr.length - 1;
            }
            File parentDir=new File("/storage/"+arr[size]);
            if(parentDir.listFiles()!=null){
                File parent[] = parentDir.listFiles();

                for (int i = 0; i < parent.length; i++) {

                    // get file path as parent[i].getAbsolutePath());

                }
            }
        }

Getting access to external storage

In order to read or write files on the external storage, your app must acquire the READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE system permissions. For example:

<manifest ...>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    ...
</manifest>

This might be useful for someone.

Numpy's histogram function returns the edges of each bin, rather than the value of the bin. This makes sense for floating-point numbers, which can lie within an interval, but may not be the desired result when dealing with discrete values or integers (0, 1, 2, etc). In particular, the length of bins returned from np.histogram is not equal to the length of the counts / density.

To get around this, I used np.digitize to quantize the input, and count the fraction of counts for each bin. You could easily edit to get the integer number of counts.

def compute_PMF(data):
    import numpy as np
    from collections import Counter
    _, bins = np.histogram(data, bins='auto', range=(data.min(), data.max()), density=False)
    h = Counter(np.digitize(data,bins) - 1)
    weights = np.asarray(list(h.values())) 
    weights = weights / weights.sum()
    values = np.asarray(list(h.keys()))
    return weights, values

A layman definition for inflation might be to convert the XML code to Java code. Just a way to understand, e.g., if we have a tag in XML, OS has to create a corresponding Java object in memory, so inflatter reads the XMLtags, and creates the corresponding objects in Java.

Here's one way to solve it. Remove non-numeric characters then cast it as a number.

cast(regexp_replace('0419 853 694', '[^0-9]+', '') as number)

Live Demo

You can achieve the effect using a container element, then just set the containing elements margin to 0 auto and it will be centered.

Markup

<div id="header">
    <div id="headerContent">
        Header text
    </div>
</div>

CSS

#header{
    width:100%; 
    background: url(yourimage);
}
#headerContent{
    margin: 0 auto; width: 960px;
}

I have downloaded tools.jar and after that I copied it into path in error message.

C:\Program Files\Java\jdk-11.0.1\bin > paste here tools.jar

After that I have restarted Spring Tool Suit 4 and everything was working. When I was trying to fix that problem I have made new environmental variable: Control Panel / System / Advenced / Environmental variables / new Name : JAVA_HOME Value: C:\Program Files\Java\jdk-11.0.1 But I do not know is it necessary.

Have you tried to change the .htaccess file that laravel suggested if the default one doesn't work? I had this similar problem and changed it to

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

and it soleved :)

If you use "hg remove b" against a file with "A" status, which means it has been added but not commited, Mercurial will respond:

  not removing b: file has been marked for add (use forget to undo)

This response is a very clear explication of the difference between remove and forget.

My understanding is that "hg forget" is for undoing an added but not committed file so that it is not tracked by version control; while "hg remove" is for taking out a committed file from version control.

This thread has a example for using hg remove against files of 7 different types of status.

There's a nice jQuery number plugin: https://github.com/teamdf/jquery-number

It allows you to change any number in the format you like, with options for decimal digits and separator characters for decimal and thousand:

$.number(12345.4556, 2);          // -> 12,345.46
$.number(12345.4556, 3, ',', ' ') // -> 12 345,456

You can use it inside input fields directly, which is nicer, using same options like above:

$("input").number(true, 2);

Or you can apply to a whole set of DOM elements using selector:

$('span.number').number(true, 2);

By "camera position," it sounds like you want to adjust the elevation and the azimuth angle that you use to view the 3D plot. You can set this with ax.view_init. I've used the below script to first create the plot, then I determined a good elevation, or elev, from which to view my plot. I then adjusted the azimuth angle, or azim, to vary the full 360deg around my plot, saving the figure at each instance (and noting which azimuth angle as I saved the plot). For a more complicated camera pan, you can adjust both the elevation and angle to achieve the desired effect.

    from mpl_toolkits.mplot3d import Axes3D
    ax = Axes3D(fig)
    ax.scatter(xx,yy,zz, marker='o', s=20, c="goldenrod", alpha=0.6)
    for ii in xrange(0,360,1):
        ax.view_init(elev=10., azim=ii)
        savefig("movie%d.png" % ii)

In Java 8 you can use String.join():

List<String> list = Arrays.asList("foo", "bar", "baz");
String joined = String.join(" and ", list); // "foo and bar and baz"

Also have a look at this answer for a Stream API example.

$ echo | mutt -a syslogs.tar.gz [email protected]

But it uses mutt, not mail (or mailx).

A jQuery solution:

$("#frame1").ready( function() {

  $("#frame1").contents().scrollTop( $("#frame1").contents().scrollTop() + 10 );

});

When using Cocoa (not CocoaTouch), you can use the className property for objects that are subclasses of NSObject.

println(now.className)

This property is not available for normal Swift objects, which aren't subclasses of NSObject (and in fact, there is no root id or object type in Swift).

class Person {
    var name: String?
}

var p = Person()
println(person.className) // <- Compiler error

In CocoaTouch, at this time there is not a way to get a string description of the type of a given variable. Similar functionality also does not exist for primitive types in either Cocoa or CocoaTouch.

The Swift REPL is able to print out a summary of values including its type, so it is possible this manner of introspection will be possible via an API in the future.

EDIT: dump(object) seems to do the trick.

great.. its the issue with empty directory only nothing else. I got my issue resolved by creating one binary file in each directory and then added them.

You might try changing this line in your persistence.xml from

<property name="hbm2ddl.auto" value="create"/>

to:

<property name="hibernate.hbm2ddl.auto" value="update"/>

This is supposed to maintain the schema to follow any changes you make to the Model each time you run the app.

Got this from JavaRanch

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))
   ...

with unsrt the problem is the format. use \bibliographystyle{ieeetr} to get refences in order of citation in document.

You could think of it like, else as in the rest of the stuff, or the other stuff, that wasn't done in the loop.

You can use Reflector and also use Add-In FileGenerator to extract source code into a project.

There is an easy way with Sharpeserializer (open source) :

http://www.sharpserializer.com/

It can directly serialize/de-serialize dictionary.

There is no need to mark your object with any attribute, nor do you have to give the object type in the Serialize method (See here ).

To install via nuget : Install-package sharpserializer

Then it is very simple :

Hello World (from the official website):

// create fake obj
var obj = createFakeObject();

// create instance of sharpSerializer
// with standard constructor it serializes to xml
var serializer = new SharpSerializer();

// serialize
serializer.Serialize(obj, "test.xml");

// deserialize
var obj2 = serializer.Deserialize("test.xml");

I use gitosis for managing this kind of stuff. Gitosis has a single user (usually called "git") that owns all the repositories, and it uses public-key-based access control to each repo. It might not suit your setup but is probably worth checking out (no pun intended).

I was having the same problem, although I solved out by creating the table using a script query instead of doing it graphically. See the snipped below:

USE [Database_Name]

You can force to revert your local directory to svn.

 svn revert -R your_local_path

To add to the options, you could also use my splitstackshape::cSplit function like this:

library(splitstackshape)
cSplit(before, "type", "_and_")
#    attr type_1 type_2
# 1:    1    foo    bar
# 2:   30    foo  bar_2
# 3:    4    foo    bar
# 4:    6    foo  bar_2

There is no "DOS command prompt". DOS fully died with Windows ME (7/11/2006). It's simply called the Command Prompt on Windows NT (which is NT, 2K, XP, Vista, 7).

There is no way to alter the screen buffer through built-in cmd.exe commands. It can be altered through Console API Functions, so you might be able to create a utility to modify it. I've never tried this myself.

Another suggestion would be to redirect output to both a file and to the screen so that you have a "hard copy" of it. Windows does not have a TEE command like Unix, but someone has remedied that.

The data parameter of ajax method allows you send data to server side.On server side you can request the data.See the code

var id=5;
$.ajax({
    type: "get",
    url: "url of server side script",
    data:{id:id},
    success: function(res){
        console.log(res);
    },
error:function(error)
{
console.log(error);
}
});

At server side receive it using $_GET variable.

$_GET['id'];

There are some really good answers on here. Let me post a different way to set your headers with the WebClient(). I will also show you how to set an API key.

        var client = new WebClient();
        string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(userName + ":" + passWord));
        client.Headers[HttpRequestHeader.Authorization] = $"Basic {credentials}";
        //If you have your data stored in an object serialize it into json to pass to the webclient with Newtonsoft's JsonConvert
        var encodedJson = JsonConvert.SerializeObject(newAccount);

        client.Headers.Add($"x-api-key:{ApiKey}");
        client.Headers.Add("Content-Type:application/json");
        try
        {
            var response = client.UploadString($"{apiurl}", encodedJson);
            //if you have a model to deserialize the json into Newtonsoft will help bind the data to the model, this is an extremely useful trick for GET calls when you have a lot of data, you can strongly type a model and dump it into an instance of that class.
            Response response1 = JsonConvert.DeserializeObject<Response>(response);

In case you don't want to mix up with default change event you can provide your custom event

$('input.test').on('value_changed', function(e){
    console.log('value changed to '+$(this).val());
});

to trigger the event on value set, you can do

$('input.test').val('I am a new value').trigger('value_changed');

This works with both Linux and Mac OSX ..

 echo $(pwd)$/$(ls file.txt)

Ok, there are a bunch of ways you can do that. Yes, you can use plain old JS. Just try:

let dt1 = new Date()
let dt2 = new Date()

Let's emulate passage using Date.prototype.setMinutes and make sure we are in range.

dt1.setMinutes(7)
dt2.setMinutes(42)
console.log('Elapsed seconds:',(dt2-dt1)/1000)

Alternatively you could use some library like js-joda, where you can easily do things like this (directly from docs):

var dt1 = LocalDateTime.parse("2016-02-26T23:55:42.123");
var dt2 = dt1
  .plusYears(6)
  .plusMonths(12)
  .plusHours(2)
  .plusMinutes(42)
  .plusSeconds(12);

// obtain the duration between the two dates
dt1.until(dt2, ChronoUnit.YEARS); // 7
dt1.until(dt2, ChronoUnit.MONTHS); // 84
dt1.until(dt2, ChronoUnit.WEEKS); // 356
dt1.until(dt2, ChronoUnit.DAYS); // 2557
dt1.until(dt2, ChronoUnit.HOURS); // 61370
dt1.until(dt2, ChronoUnit.MINUTES); // 3682242
dt1.until(dt2, ChronoUnit.SECONDS); // 220934532

There are plenty more libraries ofc, but js-joda has an added bonus of being available also in Java, where it has been extensively tested. All those tests have been migrated to js-joda, it's also immutable.

Although this is almost certainly not the OPs issue, you can also get Unable to establish SSL connection from wget if you're behind a proxy and don't have HTTP_PROXY and HTTPS_PROXY environment variables set correctly. Make sure to set HTTP_PROXY and HTTPS_PROXY to point to your proxy.

This is a common situation if you work for a large corporation.

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

The /me/friendlists endpoint and user_friendlists permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission).

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

Those errors :

"CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage"

means you haven't installed mingw32-base.

Go to http://sourceforge.net/projects/mingw/files/latest/download?source=files

and then make sure you select "mingw32-base"

Make sure you set up environment variables correctly in PATH section. "C:\MinGW\bin"

After that open CMake and Select Installation --> Delete Cache.

And click configure button again. I solved the problem this way, hope you solve the problem.

Suppose your dataframe is df and you want to change gender from 2 to 1 in participant id 5 then you should determine the row by writing "==" as you can see

 df["rowName", "columnName"] <- value
 df[df$serial.id==5, "gender"] <- 1

IOC - DIP - DI

1. Inversion of Control (IOC)
2. Dependency Inversion Principle (DIP)
3. Dependency Injection (DI)

1- IOC: abstract principle describing an aspect of some software architecture designs in which the flow of control of a system is inverted in comparison to procedural programming.

2-DIP: is Object Oriented Programming(OOP) principle(D of SOLID).

3-DI: is a software design pattern that implements inversion of control and allows a program design to follow the dependency inversion principle.

IOC & DIP are two disjoint sets and DIP is the super set of DI, service locator and some other patterns

There's a python module especially made for reading and writing to and from binary encoded data called 'struct'. Since versions of Python under 2.6 doesn't support str.format, a custom method needs to be used to create binary formatted strings.

import struct

# binary string
def bstr(n): # n in range 0-255
    return ''.join([str(n >> x & 1) for x in (7,6,5,4,3,2,1,0)])

# read file into an array of binary formatted strings.
def read_binary(path):
    f = open(path,'rb')
    binlist = []
    while True:
        bin = struct.unpack('B',f.read(1))[0] # B stands for unsigned char (8 bits)
        if not bin:
            break
        strBin = bstr(bin)
        binlist.append(strBin)
    return binlist

I think your ListBox already clear with ListBox2.Items.Clear(). The problem is that you also need to clear your dataset from previous results with ds6.Tables.Clear().

Add this in your code:

da6 = New SqlDataAdapter("select distinct(component_type) from component where   component_name='" & ListBox1.SelectedItem() & "'", con)
    ListBox1.Items.Clear()    ' clears ListBox1
    ListBox2.Items.Clear()    ' clears ListBox2
    ds6.Tables.Clear()        ' clears DataSet  <======= DON'T FORGET TO DO THIS
da6.Fill(ds6, "component")
For Each row As DataRow In ds6.Tables(0).Rows
    ListBox2.Items.Add(row.Field(Of String)("component_type"))

Following solution is very basic and simple approach to send data from VC2 to VC1 using delegate .

PS: This solution is made in Xcode 9.X and Swift 4

Declared a protocol and created a delegate var into ViewControllerB

    import UIKit

    //Declare the Protocol into your SecondVC
    protocol DataDelegate {
        func sendData(data : String)
    }

    class ViewControllerB : UIViewController {

    //Declare the delegate property in your SecondVC
        var delegate : DataDelegate?
        var data : String = "Send data to ViewControllerA."
        override func viewDidLoad() {
            super.viewDidLoad()
        }

        @IBAction func btnSendDataPushed(_ sender: UIButton) {
                // Call the delegate method from SecondVC
                self.delegate?.sendData(data:self.data)
                dismiss(animated: true, completion: nil)
            }
        }

ViewControllerA confirms the protocol and expected to receive data via delegate method sendData

    import UIKit
        // Conform the  DataDelegate protocol in ViewControllerA
        class ViewControllerA : UIViewController , DataDelegate {
        @IBOutlet weak var dataLabel: UILabel!

        override func viewDidLoad() {
            super.viewDidLoad()
        }

        @IBAction func presentToChild(_ sender: UIButton) {
            let childVC =  UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier:"ViewControllerB") as! ViewControllerB
            //Registered delegate
            childVC.delegate = self
            self.present(childVC, animated: true, completion: nil)
        }

        // Implement the delegate method in ViewControllerA
        func sendData(data : String) {
            if data != "" {
                self.dataLabel.text = data
            }
        }
    }

This webpage have an explanation and a solution.

The solution is:

To fix this problem the behavior of the kernel has to be changed, so it will no longer overcommit the memory for application requests. Finally I have included those mentioned values into the /etc/sysctl.conf file, so they get automatically applied on start-up:

vm.overcommit_memory = 2

vm.overcommit_ratio = 80

I don't know about that specific SharePoint web service, but you can decorate a page method or a web service with <WebMethod()> (in VB.NET) to ensure that it serializes to JSON. You can probably just wrap the method that webservice.asmx uses internally, in your own web service.

Dave Ward has a nice walkthrough on this.

I suppose rgba() would work here. After all, browser support for both box-shadow and rgba() is roughly the same.

/* 50% black box shadow */
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);

div {_x000D_
    width: 200px;_x000D_
    height: 50px;_x000D_
    line-height: 50px;_x000D_
    text-align: center;_x000D_
    color: white;_x000D_
    background-color: red;_x000D_
    margin: 10px;_x000D_
}_x000D_
_x000D_
div.a {_x000D_
  box-shadow: 10px 10px 10px #000;_x000D_
}_x000D_
_x000D_
div.b {_x000D_
  box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);_x000D_
}

<div class="a">100% black shadow</div>_x000D_
<div class="b">50% black shadow</div>

Normally i use a class for this:

public class ClassName
{
    public string Col1 { get; set; }
    public int Col2 { get; set; }
}

Now you can use a loop to fill a list and ToArray if you really need an array:

ClassName[] allRecords = null;
string sql = @"SELECT col1,col2
               FROM  some table";
using (var command = new SqlCommand(sql, con))
{
    con.Open();
    using (var reader = command.ExecuteReader())
    {
        var list = new List<ClassName>();
        while (reader.Read())
            list.Add(new ClassName { Col1 = reader.GetString(0), Col2 = reader.GetInt32(1) });
        allRecords = list.ToArray();
    }
}

Note that i've presumed that the first column is a string and the second an integer. Just to demonstrate that C# is typesafe and how you use the DataReader.GetXY methods.

None of the answers here quite hit the nail on the head.

How to store a datetime in MySQL with timezone info

Use two columns: DATETIME, and a VARCHAR to hold the time zone information, which may be in several forms:

A timezone or location such as America/New_York is the highest data fidelity.

A timezone abbreviation such as PST is the next highest fidelity.

A time offset such as -2:00 is the smallest amount of data in this regard.

Some key points:

• Avoid TIMESTAMP because it's limited to the year 2038, and MySQL relates it to the server timezone, which is probably undesired.
• A time offset should not be stored naively in an INT field, because there are half-hour and quarter-hour offsets.

If it's important for your use case to have MySQL compare or sort these dates chronologically, DATETIME has a problem:

'2009-11-10 11:00:00 -0500' is before '2009-11-10 10:00:00 -0700' in terms of "instant in time", but they would sort the other way when inserted into a DATETIME.

You can do your own conversion to UTC. In the above example, you would then have
'2009-11-10 16:00:00' and '2009-11-10 17:00:00' respectively, which would sort correctly. When retrieving the data, you would then use the timezone info to revert it to its original form.

One recommendation which I quite like is to have three columns:

• local_time DATETIME
• utc_time DATETIME
• time_zone VARCHAR(X) where X is appropriate for what kind of data you're storing there. (I would choose 64 characters for timezone/location.)

An advantage to the 3-column approach is that it's explicit: with a single DATETIME column, you can't tell at a glance if it's been converted to UTC before insertion.

Regarding the descent of accuracy through timezone/abbreviation/offset:

• If you have the user's timezone/location such as America/Juneau, you can know accurately what the wall clock time is for them at any point in the past or future (barring changes to the way Daylight Savings is handled in that location). The start/end points of DST, and whether it's used at all, are dependent upon location, so this is the only reliable way.
• If you have a timezone abbreviation such as MST, (Mountain Standard Time) or a plain offset such as -0700, you will be unable to predict a wall clock time in the past or future. For example, in the United States, Colorado and Arizona both use MST, but Arizona doesn't observe DST. So if the user uploads his cat photo at 14:00 -0700 during the winter months, was he in Arizona or California? If you added six months exactly to that date, would it be 14:00 or 13:00 for the user?

These things are important to consider when your application has time, dates, or scheduling as core function.

Since you are asking in the context of a facebook app, you might want to consider detecting this at the server when the initial request is made. Facebook will pass along a bunch of querystring data including the fb_sig_user key if it is called from an iframe.

Since you probably need to check and use this data anyway in your app, use it to determine the the appropriate context to render.

To understand it better, run this following program (in jdk1.7.x) :

$ java -Xms1025k -Xmx1025k -XshowSettings:vm  MemoryTest

This will print jvm options and the used, free, total and maximum memory available in jvm.

public class MemoryTest {    
    public static void main(String args[]) {
                System.out.println("Used Memory   :  " + (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) + " bytes");
                System.out.println("Free Memory   : " + Runtime.getRuntime().freeMemory() + " bytes");
                System.out.println("Total Memory  : " + Runtime.getRuntime().totalMemory() + " bytes");
                System.out.println("Max Memory    : " + Runtime.getRuntime().maxMemory() + " bytes");            
        }
}

How to find out what this MySQL Error is trying to say:

#1064 - You have an error in your SQL syntax;

This error has no clues in it. You have to double check all of these items to see where your mistake is:

1. You have omitted, or included an unnecessary symbol: !@#$%^&*()-_=+[]{}\|;:'",<>/?
2. A misplaced, missing or unnecessary keyword: select, into, or countless others.
3. You have unicode characters that look like ascii characters in your query but are not recognized.
4. Misplaced, missing or unnecessary whitespace or newlines between keywords.
5. Unmatched single quotes, double quotes, parenthesis or braces.

Take away as much as you can from the broken query until it starts working. And then use PostgreSQL next time that has a sane syntax reporting system.

Make sure to use the !important attribute. This dramatically increases the likelihood your styles are retained when printed.

#example1 {
    background:url(image.png) no-repeat !important;
}

#example2 {
    background-color: #123456 !important;
}

Here is my function to get the matches :

function getAllMatches(regex, text) {
    if (regex.constructor !== RegExp) {
        throw new Error('not RegExp');
    }

    var res = [];
    var match = null;

    if (regex.global) {
        while (match = regex.exec(text)) {
            res.push(match);
        }
    }
    else {
        if (match = regex.exec(text)) {
            res.push(match);
        }
    }

    return res;
}

// Example:

var regex = /abc|def|ghi/g;
var res = getAllMatches(regex, 'abcdefghi');

res.forEach(function (item) {
    console.log(item[0]);
});

If you have too many table column and it is not adjusted in angular table using md-table, then paste the following style in component.css file. It will work like a charm with scroll view horizontally.

.mat-table__wrapper .mat-table {
    min-width: auto !important;
    width: 100% !important; }

.mat-header-row {
    width: 100%; }

.mat-row {
    width: 100%;
}

Add this style to alter your column separately.

.mat-column-{colum-name} {
    flex: 0 0 25% !important;
    min-width: 104px !important;
}

Alternatively check this link, (where the code above came from), for more detail.

use below code

 Task.WaitAll(Task.Run(async () => await GetResponse<MyObject>("my url")));

If you are looking for a plain JS solution, then you just use insertBefore() against nextSibling.

Something like:

parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);

Note that default value of nextSibling is null, so, you don't need to do anything special for that.

Update: You don't even need the if checking presence of parentGuest.nextSibling like the currently accepted answer does, because if there's no next sibling, it will return null, and passing null to the 2nd argument of insertBefore() means: append at the end.

Reference:

• nextSibling
• insertBefore

.

IF you are using jQuery (ignore otherwise, I have stated plain JS answer above), you can leverage the convenient after() method:

$("#one").after("<li id='two'>");

Reference:

• jQuery after()

Worked here too:

Sub test544()

  Dim chromePath As String

  chromePath = """C:\Program Files\Google\Chrome\Application\chrome.exe"""

  Shell (chromePath & " -url http:google.ca")

End Sub

   extend = function(destination, source) {   
          for (var property in source) {
            destination[property] = source[property];
          }
          return destination;
    };

Extending JavaScript

You could also add filters into the for loop.

When you want to check if a value is provided for a field, that field may be a string , an array, or undifined. So, the following is enough

function isSet($param)
{
    return (is_array($param) && count($param)) || trim($param) !== '';
}

To run a java file in Android ensure your class has the main method. In Android Studio 3.5 just right click inside the file and select "Run 'Filename.main()'" or click on "Run" on the menu and select "Run Filename" from the resulting drop-down menu.

A class that is declared using the abstract keyword is known as abstract class. Abstraction is a process of hiding the data implementation details, and showing only functionality to the user. Abstraction lets you focus on what the object does instead of how it does it.

Main things of abstract class

• An abstract class may or may not contain abstract methods.There can be non abstract methods.

  An abstract method is a method that is declared without an implementation (without braces, and followed by a semicolon), like this:

  ex : abstract void moveTo(double deltaX, double deltaY);

• If a class has at least one abstract method then that class must be abstract

• Abstract classes may not be instantiated (You are not allowed to create object of Abstract class)

• To use an abstract class, you have to inherit it from another class. Provide implementations to all the abstract methods in it.

• If you inherit an abstract class, you have to provide implementations to all the abstract methods in it.

Declare abstract class Specifying abstract keyword before the class during declaration makes it abstract. Have a look at the code below:

abstract class AbstractDemo{ }

Declare abstract method Specifying abstract keyword before the method during declaration makes it abstract. Have a look at the code below,

abstract void moveTo();//no body

Why we need to abstract classes

In an object-oriented drawing application, you can draw circles, rectangles, lines, Bezier curves, and many other graphic objects. These objects all have certain states (for ex -: position, orientation, line color, fill color) and behaviors (for ex -: moveTo, rotate, resize, draw) in common. Some of these states and behaviors are the same for all graphic objects (for ex : fill color, position, and moveTo). Others require different implementation(for ex: resize or draw). All graphic objects must be able to draw or resize themselves, they just differ in how they do it.

This is a perfect situation for an abstract superclass. You can take advantage of the similarities, and declare all the graphic objects to inherit from the same abstract parent object (for ex : GraphicObject) as shown in the following figure.

First, you declare an abstract class, GraphicObject, to provide member variables and methods that are wholly shared by all subclasses, such as the current position and the moveTo method. GraphicObject also declared abstract methods, such as draw or resize, that need to be a implemented by all subclasses but must be implemented in different ways. The GraphicObject class can look something like this:

abstract class GraphicObject {

  void moveTo(int x, int y) {
    // Inside this method we have to change the position of the graphic 
    // object according to x,y     
    // This is the same in every GraphicObject. Then we can implement here. 
  }

  abstract void draw(); // But every GraphicObject drawing case is 
                        // unique, not common. Then we have to create that 
                        // case inside each class. Then create these    
                        // methods as abstract 
  abstract void resize();
}

Usage of abstract method in sub classes Each non abstract subclasses of GraphicObject, such as Circle and Rectangle, must provide implementations for the draw and resize methods.

class Circle extends GraphicObject {
  void draw() {
    //Add to some implementation here
  }
  void resize() {
    //Add to some implementation here   
  }
}
class Rectangle extends GraphicObject {
  void draw() {
    //Add to some implementation here
  }
  void resize() {
    //Add to some implementation here
  }
}

Inside the main method you can call all methods like this:

public static void main(String args[]){
   GraphicObject c = new Circle();
   c.draw();
   c.resize();
   c.moveTo(4,5);   
}

Ways to achieve abstraction in Java

There are two ways to achieve abstraction in java

• Abstract class (0 to 100%)
• Interface (100%)

Abstract class with constructors, data members, methods, etc

abstract class GraphicObject {

  GraphicObject (){
    System.out.println("GraphicObject  is created");
  }
  void moveTo(int y, int x) {
       System.out.println("Change position according to "+ x+ " and " + y);
  }
  abstract void draw();
}

class Circle extends GraphicObject {
  void draw() {
    System.out.println("Draw the Circle");
  }
}

class TestAbstract {  
 public static void main(String args[]){

   GraphicObject  grObj = new Circle ();
   grObj.draw();
   grObj.moveTo(4,6);
 }
}

Output:

GraphicObject  is created
Draw the Circle
Change position according to 6 and 4

Remember two rules:

• If the class has few abstract methods and few concrete methods, declare it as an abstract class.

• If the class has only abstract methods, declare it as an interface.

Below I have shown an example using both Ref and out. Now, you all will be cleared about ref and out.

In below mentioned example when i comment //myRefObj = new myClass { Name = "ref outside called!! " }; line, will get an error saying "Use of unassigned local variable 'myRefObj'", but there is no such error in out.

Where to use Ref: when we are calling a procedure with an in parameter and the same parameter will be used to store the output of that proc.

Where to use Out: when we are calling a procedure with no in parameter and teh same param will be used to return the value from that proc. Also note the output

public partial class refAndOutUse : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        myClass myRefObj;
        myRefObj = new myClass { Name = "ref outside called!!  <br/>" };
        myRefFunction(ref myRefObj);
        Response.Write(myRefObj.Name); //ref inside function

        myClass myOutObj;
        myOutFunction(out myOutObj);
        Response.Write(myOutObj.Name); //out inside function
    }

    void myRefFunction(ref myClass refObj)
    {
        refObj.Name = "ref inside function <br/>";
        Response.Write(refObj.Name); //ref inside function
    }
    void myOutFunction(out myClass outObj)
    {
        outObj = new myClass { Name = "out inside function <br/>" }; 
        Response.Write(outObj.Name); //out inside function
    }
}

public class myClass
{
    public string Name { get; set; }
} 

Do you want to get a substring of a string from start index to the last index of one of its characters? If so, you may choose one of the following Swift 2.0+ methods.

Methods that require Foundation

Get a substring that includes the last index of a character:

import Foundation

let string = "www.stackoverflow.com"
if let rangeOfIndex = string.rangeOfCharacterFromSet(NSCharacterSet(charactersInString: "."), options: .BackwardsSearch) {
    print(string.substringToIndex(rangeOfIndex.endIndex))
}

// prints "www.stackoverflow."

Get a substring that DOES NOT include the last index of a character:

import Foundation

let string = "www.stackoverflow.com"
if let rangeOfIndex = string.rangeOfCharacterFromSet(NSCharacterSet(charactersInString: "."), options: .BackwardsSearch) {
    print(string.substringToIndex(rangeOfIndex.startIndex))
}

// prints "www.stackoverflow"

If you need to repeat those operations, extending String can be a good solution:

import Foundation

extension String {
    func substringWithLastInstanceOf(character: Character) -> String? {
        if let rangeOfIndex = rangeOfCharacterFromSet(NSCharacterSet(charactersInString: String(character)), options: .BackwardsSearch) {
            return self.substringToIndex(rangeOfIndex.endIndex)
        }
        return nil
    }
    func substringWithoutLastInstanceOf(character: Character) -> String? {
        if let rangeOfIndex = rangeOfCharacterFromSet(NSCharacterSet(charactersInString: String(character)), options: .BackwardsSearch) {
            return self.substringToIndex(rangeOfIndex.startIndex)
        }
        return nil
    }
}

print("www.stackoverflow.com".substringWithLastInstanceOf("."))
print("www.stackoverflow.com".substringWithoutLastInstanceOf("."))

/*
prints:
Optional("www.stackoverflow.")
Optional("www.stackoverflow")
*/

Methods that DO NOT require Foundation

Get a substring that includes the last index of a character:

let string = "www.stackoverflow.com"
if let reverseIndex = string.characters.reverse().indexOf(".") {
    print(string[string.startIndex ..< reverseIndex.base])
}

// prints "www.stackoverflow."

Get a substring that DOES NOT include the last index of a character:

let string = "www.stackoverflow.com"
if let reverseIndex = string.characters.reverse().indexOf(".") {
    print(string[string.startIndex ..< reverseIndex.base.advancedBy(-1)])
}

// prints "www.stackoverflow"

If you need to repeat those operations, extending String can be a good solution:

extension String {
    func substringWithLastInstanceOf(character: Character) -> String? {
        if let reverseIndex = characters.reverse().indexOf(".") {
            return self[self.startIndex ..< reverseIndex.base]
        }
        return nil
    }
    func substringWithoutLastInstanceOf(character: Character) -> String? {
        if let reverseIndex = characters.reverse().indexOf(".") {
            return self[self.startIndex ..< reverseIndex.base.advancedBy(-1)]
        }
        return nil
    }
}

print("www.stackoverflow.com".substringWithLastInstanceOf("."))
print("www.stackoverflow.com".substringWithoutLastInstanceOf("."))

/*
prints:
Optional("www.stackoverflow.")
Optional("www.stackoverflow")
*/

1. Why is this happening?

There are two types of messages in FCM (Firebase Cloud Messaging):

1. Display Messages: These messages trigger the onMessageReceived() callback only when your app is in foreground
2. Data Messages: Theses messages trigger the onMessageReceived() callback even if your app is in foreground/background/killed

NOTE: Firebase team have not developed a UI to send data-messages to your devices, yet. You should use your server for sending this type!

2. How to?

To achieve this, you have to perform a POST request to the following URL:

POST https://fcm.googleapis.com/fcm/send

Headers

• Key: Content-Type, Value: application/json
• Key: Authorization, Value: key=<your-server-key>

Body using topics

{
    "to": "/topics/my_topic",
    "data": {
        "my_custom_key": "my_custom_value",
        "my_custom_key2": true
     }
}

Or if you want to send it to specific devices

{
    "data": {
        "my_custom_key": "my_custom_value",
        "my_custom_key2": true
     },
    "registration_ids": ["{device-token}","{device2-token}","{device3-token}"]
}

NOTE: Be sure you're not adding JSON key notification
NOTE: To get your server key, you can find it in the firebase console: Your project -> settings -> Project settings -> Cloud messaging -> Server Key

3. How to handle the push notification message?

This is how you handle the received message:

@Override
public void onMessageReceived(RemoteMessage remoteMessage) { 
     Map<String, String> data = remoteMessage.getData();
     String myCustomKey = data.get("my_custom_key");

     // Manage data
}

I defined an git alias to achieve just this (before I found this question).

It's a short bash function which saves the current path, switch to the git repo, does a checkout and return where it started.

git checkto develop ~/my_project_git

This e.g. would checkout the develop branch into "~/my_project_git" directory.

This is the alias code inside ~/.gitconfig:

[alias]
    checkTo = "!f(){ [ -z \"$1\" ] && echo \"Need to specify branch.\" && \
               exit 1; [ -z \"$2\" ] && echo \"Need to specify target\
               dir\" && exit 2; cDir=\"$(pwd)\"; cd \"$2\"; \
               git checkout \"$1\"; cd \"$cDir\"; };f"

To quote the help page (try ?integer), bolded portion mine:

Integer vectors exist so that data can be passed to C or Fortran code which expects them, and so that (small) integer data can be represented exactly and compactly.

Note that current implementations of R use 32-bit integers for integer vectors, so the range of representable integers is restricted to about +/-2*10^9: doubles can hold much larger integers exactly.

Like the help page says, R's integers are signed 32-bit numbers so can hold between -2147483648 and +2147483647 and take up 4 bytes.

R's numeric is identical to an 64-bit double conforming to the IEEE 754 standard. R has no single precision data type. (source: help pages of numeric and double). A double can store all integers between -2^53 and 2^53 exactly without losing precision.

We can see the data type sizes, including the overhead of a vector (source):

> object.size(1:1000)
4040 bytes
> object.size(as.numeric(1:1000))
8040 bytes

Because of the GDPR it makes no sense to use the iframe, you should rather use the object tag with the embed tag and also use the embed link.

<object width="100%" height="333">
  <param name="movie" value="https://www.youtube-nocookie.com/embed/Sdg0ef2PpBw">
  <embed src="https://www.youtube-nocookie.com/embed/Sdg0ef2PpBw" width="100%" height="333">
</object>

You should also activate the extended data protection mode function to receive the no cookie url.

type="application/x-shockwave-flash" 

flash does not have to be used

Nocookie, however, means that data is still being transmitted, namely the thumbnail that is loaded from YouTube. But at least data is no longer passed on to advertising networks (as example DoubleClick). And no user data is stored on your website by youtube.

The easiest way is to do:

chmod -R u+rwX,go+rX,go-w /path/to/dir

which basically means:

to change file modes -Recursively by giving:

• user: read, write and eXecute permissions,
• group and other users: read and eXecute permissions, but not -write permission.

Please note that X will make a directory executable, but not a file, unless it's already searchable/executable.

+X - make a directory or file searchable/executable by everyone if it is already searchable/executable by anyone.

Please check man chmod for more details.

See also: How to chmod all directories except files (recursively)? at SU

A solution would be to use a combination of end and key (quoting) :

• end() advances array 's internal pointer to the last element, and returns its value.
• key() returns the index element of the current array position.

So, a portion of code such as this one should do the trick :

$array = array(
    'first' => 123,
    'second' => 456,
    'last' => 789, 
);

end($array);         // move the internal pointer to the end of the array
$key = key($array);  // fetches the key of the element pointed to by the internal pointer

var_dump($key);

Will output :

string 'last' (length=4)

i.e. the key of the last element of my array.

After this has been done the array's internal pointer will be at the end of the array. As pointed out in the comments, you may want to run reset() on the array to bring the pointer back to the beginning of the array.

Easier way is also to do this.

let elementReference = document.querySelector('<your css, #id selector>');
    if (elementReference instanceof HTMLElement) {
        elementReference.focus();
    }

$destroy can refer to 2 things: method and event

1. method - $scope.$destroy

.directive("colorTag", function(){
  return {
    restrict: "A",
    scope: {
      value: "=colorTag"
    },
    link: function (scope, element, attrs) {
      var colors = new App.Colors();
      element.css("background-color", stringToColor(scope.value));
      element.css("color", contrastColor(scope.value));

      // Destroy scope, because it's no longer needed.
      scope.$destroy();
    }
  };
})

2. event - $scope.$on("$destroy")

See @SunnyShah's answer.

Use NSLog() like this:

NSLog(@"The code runs through here!");

Or like this - with placeholders:

float aFloat = 5.34245;
NSLog(@"This is my float: %f \n\nAnd here again: %.2f", aFloat, aFloat);

In NSLog() you can use it like + (id)stringWithFormat:(NSString *)format, ...

float aFloat = 5.34245;
NSString *aString = [NSString stringWithFormat:@"This is my float: %f \n\nAnd here again: %.2f", aFloat, aFloat];

You can add other placeholders, too:

float aFloat = 5.34245;
int aInteger = 3;
NSString *aString = @"A string";
NSLog(@"This is my float: %f \n\nAnd here is my integer: %i \n\nAnd finally my string: %@", aFloat, aInteger, aString);

It's too late to answer this question, but it could help for new readers, It seems version issues. I ran all these tests with spring 4.1.4 and found that the order of @RequestBody and @RequestParam doesn't matter.

1. same as your result
2. same as your result
3. gave body= "name=abc", and name = "abc"
4. Same as 3.
5. body ="name=abc", name = "xyz,abc"
6. same as 5.

My understanding is that adding r+ opens for both read and write (just like w+, though as pointed out in the comment, will truncate the file). The b just opens it in binary mode, which is supposed to be less aware of things like line separators (at least in C++).

You could do

[A1].Value = "'O1/01/13 00:00"

if you really mean to add it as text (note the apostrophe as the first character).

The [A1].Value is VBA shorthand for Range("A1").Value.

If you want to enter a date, you could instead do (edited order with thanks to @SiddharthRout):

[A1].NumberFormat = "mm/dd/yyyy hh:mm;@"
[A1].Value = DateValue("01/01/2013 00:00")

The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.

Also, I didn't understand when the accepted answer said "it defaults to node server.js". I think the documentation clarifies the default behavior:

npm-start

Start a package

Synopsis

npm start [-- <args>]

Description

This runs an arbitrary command specified in the package's "start" property of its "scripts" object. If no "start" property is specified on the "scripts" object, it will run node server.js.

In summary, running npm start could do one of two things:

1. npm start {command_name}: Run an arbitrary command (i.e. if such command is specified in the start property of package.json's scripts object)
2. npm start: Else if no start property exists (or no command_name is passed): Run node server.js, (which may not be appropriate, for example the OP doesn't have server.js; the OP runs nodeapp.js )
3. I said I would list only 2 items, but are other possibilities (i.e. error cases). For example, if there is no package.json in the directory where you run npm start, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'

In browsers other than Internet Explorer you need to use a small Flash object to manipulate the clipboard, e.g.

• Auto copy to clipboard

You have to first declare delegate's type because delegates are strongly typed:

public void MyCallbackDelegate( string str );

public void DoRequest(string request, MyCallbackDelegate callback)
{
     // do stuff....
     callback("asdf");
}

As an exteme turnaround, when you cannot do an alter to your date column or to update the values, or while these modifications take place, you can do a select using a case/when.

SELECT CASE ModificationDate WHEN '0000-00-00 00:00:00' THEN '1970-01-01 01:00:00' ELSE ModificationDate END AS ModificationDate FROM Project WHERE projectId=1;

In addition to top, you can use System Monitor (System - Administration - System Monitor, then select Processes tab). Select View - All Processes, go to Edit - Preferences and enable Virtual Memory column. Sort either by this column, or by Memory column

One more variant is using very powerfull JOOR library https://github.com/jOOQ/jOOR

MyObject myObject = new MyObject()
on(myObject).get("privateField");  

It allows to modify any fields like final static constants and call yne protected methods without specifying concrete class in the inheritance hierarhy

Both JBoss and Tomcat are Java servlet application servers, but JBoss is a whole lot more. The substantial difference between the two is that JBoss provides a full Java Enterprise Edition (Java EE) stack, including Enterprise JavaBeans and many other technologies that are useful for developers working on enterprise Java applications.

Tomcat is much more limited. One way to think of it is that JBoss is a Java EE stack that includes a servlet container and web server, whereas Tomcat, for the most part, is a servlet container and web server.

Your Customer class has to be discovered by CDI as a bean. For that you have two options:

1. Put a bean defining annotation on it. As @Model is a stereotype it's why it does the trick. A qualifier like @Named is not a bean defining annotation, reason why it doesn't work

2. Change the bean discovery mode in your bean archive from the default "annotated" to "all" by adding a beans.xml file in your jar.

Keep in mind that @Named has only one usage : expose your bean to the UI. Other usages are for bad practice or compatibility with legacy framework.

From psql command line:

\COPY my_table TO 'filename' CSV HEADER

no semi-colon at the end.

Dir

Use the dir command. Type in dir /? for help and options.

dir /a:d /b

Redirect

Then use a redirect to save the list to a file.

> list.txt

Together

dir /a:d /b > list.txt

This will output just the names of the directories. if you want the full path of the directories use this below.

Full Path

for /f "delims=" %%D in ('dir /a:d /b') do echo %%~fD

Alternative

other method just using the for command. See for /? for help and options. This can output just the name %%~nxD or the full path %%~fD

for /d %%D in (*) do echo %%~fD

Notes

To use these commands directly on the command line, change the double percent signs to single percent signs. %% to %

To redirect the for methods, just add the redirect after the echo statements. Use the double arrow >> redirect here to append to the file, else only the last statement will be written to the file due to overwriting all the others.

... echo %%~fD>> list.txt

Elaborating on the answer provided by Brian R. Bondy: Here's an example that shows why you can't simply size the output buffer to the number of wide characters in the source string:

#include <windows.h>
#include <stdio.h>
#include <wchar.h>
#include <string.h>

/* string consisting of several Asian characters */
wchar_t wcsString[] = L"\u9580\u961c\u9640\u963f\u963b\u9644";

int main() 
{

    size_t wcsChars = wcslen( wcsString);

    size_t sizeRequired = WideCharToMultiByte( 950, 0, wcsString, -1, 
                                               NULL, 0,  NULL, NULL);

    printf( "Wide chars in wcsString: %u\n", wcsChars);
    printf( "Bytes required for CP950 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);

    sizeRequired = WideCharToMultiByte( CP_UTF8, 0, wcsString, -1,
                                        NULL, 0,  NULL, NULL);
    printf( "Bytes required for UTF8 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);
}

And the output:

Wide chars in wcsString: 6
Bytes required for CP950 encoding (excluding NUL terminator): 12
Bytes required for UTF8 encoding (excluding NUL terminator): 18

Your query translates to:

SELECT name FROM users WHERE id IN ('Array');

Or something to that affect.

Try using prepared queries instead, something like:

$numbers = explode(',', $string);
$prepare = array_map(function(){ return '?'; }, $numbers);
$statement = mysqli_prepare($link , "SELECT name FROM users WHERE id IN ('".implode(',', $prepare)."')");
if($statement) {
   $ints = array_map(function(){ return 'i'; }, $numbers);
   call_user_func_array("mysqli_stmt_bind_param", array_merge(
      array($statement, implode('', $ints)), $numbers
   ));
   $results = mysqli_stmt_execute($statement);
   // do something with results 
   // ...
}

You just need parentheses around your select:

SET @times = (SELECT COUNT(DidWin) FROM ...)

Or you can do it like this:

SELECT @times = COUNT(DidWin) FROM ...

Today, in Oracle 12c or newer, you probably have the column defined as GENERATED ... AS IDENTITY, and Oracle takes care of the sequence itself.

You can use an ALTER TABLE Statement to modify "START WITH" of the identity.

SELECT (EXTRACT(epoch FROM (SELECT (NOW() - '2014-08-02 08:10:56')))/86400)::int

Just provide the env values on command line

USER_ID='abc' USER_KEY='def' node app.js

I wanted to show how powerful it can be aside from just checking "-lt".

Example: I used it to calculate time differences take from Windows event view Application log:

Get the difference between the two date times:

PS> $Obj = ((get-date "10/22/2020 12:51:1") - (get-date "10/22/2020 12:20:1 "))

Object created:

PS> $Obj


Days              : 0
Hours             : 0
Minutes           : 31
Seconds           : 0
Milliseconds      : 0

TotalMinutes      : 31
TotalSeconds      : 1860
TotalMilliseconds : 1860000

Access an item directly:

Consider the outcome of the tool 'stat':

You can see here the three dates for Access/modify/change. There is no created date. You can only really be sure when the file contents were modified (the "modify" field) or its inode changed (the "change" field).

Examples of when both fields get updated:

"Modify" will be updated if someone concatenated extra information to the end of the file.

"Change" will be updated if someone changed permissions via chmod.

In PHP and C++ you can use the printf() function

printf("$%01.2f", $money);

Class methods can't change or know the value of any instance variable. That should be the criteria for knowing if an instance method can be a class method.

https://github.com/blueimp/JavaScript-Load-Image is a modern javascript library that can not only extract the exif orientation flag - it can also correctly mirror/rotate JPEG images on the client side.

I just solved the same problem with this library: JS Client-Side Exif Orientation: Rotate and Mirror JPEG Images

Forget about using success and error method.

Both methods have been deprecated in angular 1.4. Basically, the reason behind the deprecation is that they are not chainable-friendly, so to speak.

With the following example, I'll try to demonstrate what I mean about success and error being not chainable-friendly. Suppose we call an API that returns a user object with an address:

User object:

{name: 'Igor', address: 'San Francisco'}

Call to the API:

$http.get('/user')
    .success(function (user) {
        return user.address;   <---  
    })                            |  // you might expect that 'obj' is equal to the
    .then(function (obj) {   ------  // address of the user, but it is NOT

        console.log(obj); // -> {name: 'Igor', address: 'San Francisco'}
    });
};

What happened?

Because success and error return the original promise, i.e. the one returned by $http.get, the object passed to the callback of the then is the whole user object, that is to say the same input to the preceding success callback.

If we had chained two then, this would have been less confusing:

$http.get('/user')
    .then(function (user) {
        return user.address;  
    })
    .then(function (obj) {  
        console.log(obj); // -> 'San Francisco'
    });
};

You should use a callback parameter:

function Typer(callback)
{
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];
    var interval = setInterval(function() {
        if(i == srcText.length - 1) {
            clearInterval(interval);
            callback();
            return;
        }
        i++;
        result += srcText[i].replace("\n", "<br />");
        $("#message").html(result);
    },
    100);
    return true;


}

function playBGM () {
    alert("Play BGM function");
    $('#bgm').get(0).play();
}

Typer(function () {
    playBGM();
});

// or one-liner: Typer(playBGM);

So, you pass a function as parameter (callback) that will be called in that if before return.

Also, this is a good article about callbacks.

I recently used Spring Security 3.0 for this (combined with Wicket btw), and am quite happy with it. Here's a good thorough tutorial and documentation. Also take a look at this tutorial which gives a good explanation of the hashing/salting/decoding setup for Spring Security 2.

Here what i found. C:\Users\User\AppData\Local\Packages\Microsoft.MicrosoftStickyNotes_8wekyb3d8bbwe\TempState

There is snapshot of your sticky note in .png format. Open it and create your new note.

A self join is simply when you join a table with itself. There is no SELF JOIN keyword, you just write an ordinary join where both tables involved in the join are the same table. One thing to notice is that when you are self joining it is necessary to use an alias for the table otherwise the table name would be ambiguous.

It is useful when you want to correlate pairs of rows from the same table, for example a parent - child relationship. The following query returns the names of all immediate subcategories of the category 'Kitchen'.

SELECT T2.name
FROM category T1
JOIN category T2
ON T2.parent = T1.id
WHERE T1.name = 'Kitchen'

To parse JSON in VBA without adding a huge library to your workbook project, I created the following solution. It's extremely fast and stores all of the keys and values in a dictionary for easy access:

Function ParseJSON(json$, Optional key$ = "obj") As Object
    p = 1
    token = Tokenize(json)
    Set dic = CreateObject("Scripting.Dictionary")
    If token(p) = "{" Then ParseObj key Else ParseArr key
    Set ParseJSON = dic
End Function

Function ParseObj(key$)
    Do: p = p + 1
        Select Case token(p)
            Case "]"
            Case "[":  ParseArr key
            Case "{"
                       If token(p + 1) = "}" Then
                           p = p + 1
                           dic.Add key, "null"
                       Else
                           ParseObj key
                       End If
            
            Case "}":  key = ReducePath(key): Exit Do
            Case ":":  key = key & "." & token(p - 1)
            Case ",":  key = ReducePath(key)
            Case Else: If token(p + 1) <> ":" Then dic.Add key, token(p)
        End Select
    Loop
End Function

Function ParseArr(key$)
    Dim e&
    Do: p = p + 1
        Select Case token(p)
            Case "}"
            Case "{":  ParseObj key & ArrayID(e)
            Case "[":  ParseArr key
            Case "]":  Exit Do
            Case ":":  key = key & ArrayID(e)
            Case ",":  e = e + 1
            Case Else: dic.Add key & ArrayID(e), token(p)
        End Select
    Loop
End Function

The code above does use a few helper functions, but the above is the meat of it.

The strategy used here is to employ a recursive tokenizer. I found it interesting enough to write an article about this solution on Medium. It explains the details.

Here is the full (yet surprisingly short) code listing, including all of the helper functions:

I had just the same problem, here's how to deal with it:

1. adb shell to the device
2. su
3. ls -l and check current access rights on the file you need. You'll need that later.
4. go to the file needed and: chmod 777 file.ext. Note: now you have a temporary security issue. You've just allowed all the rights to everyone! Consider adding just R for users.
5. open another console and: adb pull /path/to/file.ext c:\pc\path\to\file.exe
6. Important: after you're done, revert the access rights back to the previous value (point 3)

Someone mentioned something similar earlier.

To display the item number on the repeater you can use the Container.ItemIndex property.

<asp:repeater id="rptRepeater" runat="server">
    <itemtemplate>
        Item <%# Container.ItemIndex + 1 %>| <%# Eval("Column1") %>
    </itemtemplate>

Dim strFirstAddress As String
Dim searchlast As Range
Dim search As Range

Set search = ActiveSheet.Range("A1:A100")
Set searchlast = search.Cells(search.Cells.Count)

Set rngFindValue = ActiveSheet.Range("A1:A100").Find(Text, searchlast, xlValues)
If Not rngFindValue Is Nothing Then
  strFirstAddress = rngFindValue.Address
  Do
    Set rngFindValue = search.FindNext(rngFindValue)
  Loop Until rngFindValue.Address = strFirstAddress

Another way to do it in the for loop

void rm_nl(string &s) {
    for (int p = s.find("\n"); p != (int) string::npos; p = s.find("\n"))
    s.erase(p,1);
}

Usage:

string data = "\naaa\nbbb\nccc\nddd\n";
rm_nl(data); 
cout << data; // data = aaabbbcccddd

more correct would be:

export pid=`ps aux | grep process_name | awk 'NR==1{print $2}' | cut -d' ' -f1`;kill -9 $pid

tf.nn.softmax computes the forward propagation through a softmax layer. You use it during evaluation of the model when you compute the probabilities that the model outputs.

tf.nn.softmax_cross_entropy_with_logits computes the cost for a softmax layer. It is only used during training.

The logits are the unnormalized log probabilities output the model (the values output before the softmax normalization is applied to them).

What you need, according to your comments, is a 'BLOB' (Binary Large OBject) for both image and resume.

From the StringBuilder Class documentation:

The String object is immutable. Every time you use one of the methods in the System.String class, you create a new string object in memory, which requires a new allocation of space for that new object. In situations where you need to perform repeated modifications to a string, the overhead associated with creating a new String object can be costly. The System.Text.StringBuilder class can be used when you want to modify a string without creating a new object. For example, using the StringBuilder class can boost performance when concatenating many strings together in a loop.

Without VBA...

If you can use a helper column, you can use the MATCH function to test if a value in one column exists in another column (or in another column on another worksheet). It will return an Error if there is no match

To simply identify duplicates, use a helper column

Assume data in Sheet1, Column A, and another list in Sheet2, Column A. In your helper column, row 1, place the following formula:

=If(IsError(Match(A1, 'Sheet2'!A:A,False)),"","Duplicate")

Drag/copy this forumla down, and it should identify the duplicates.

To highlight cells, use conditional formatting:

With some tinkering, you can use this MATCH function in a Conditional Formatting rule which would highlight duplicate values. I would probably do this instead of using a helper column, although the helper column is a great way to "see" results before you make the conditional formatting rule.

Something like:

=NOT(ISERROR(MATCH(A1, 'Sheet2'!A:A,FALSE)))

For Excel 2007 and prior, you cannot use conditional formatting rules that reference other worksheets. In this case, use the helper column and set your formatting rule in column A like:

=B1="Duplicate"

This screenshot is from the 2010 UI, but the same rule should work in 2007/2003 Excel.

You can find module code by first listing the modules:

help("modules")

This spits out a list of modules Python can import. At the bottom of this list is a phrase:

Enter any module name to get more help. Or, type "modules spam" to search for modules whose name or summary contain the string "spam".

To find module location:

help("module_Name")

for example:

help("signal")

A lot of information here. Scroll to the bottom to find its location

/usr/lib/python3.5/signal.py

Copy link. To see code, after exiting Python REPL:

nano /usr/lib/python3.5/signal.py

You can do this in jEdit, by using the "Return value of a BeanShell snippet" option in jEdit's find and replace dialog. Just search for " [a-z]" and replace it by " _0.toUpperCase()" (without quotes)

You can make a default constraint on this column that will put a default getdate() as a value.

Example:

alter table dbo.TABLE 
add constraint df_TABLE_DATE default getdate() for DATE_COLUMN

In my case, I wanted to unit test that users weren't able to verify their email addresses after 1 hour had passed, so I didn't want to do any of the other answers since they would also persist when not unit testing, so I ended up just manually updating the row after insert:

// Create new user
$user = factory(User::class)->create();

// Add an email verification token to the 
// email_verification_tokens table
$token = $user->generateNewEmailVerificationToken();

// Get the time 61 minutes ago
$created_at = (new Carbon())->subMinutes(61);

// Do the update
\DB::update(
    'UPDATE email_verification_tokens SET created_at = ?',
    [$created_at]
);

Note: For anything other than unit testing, I would look at the other answers here.

I used this code to show the dialog at the bottom of the screen:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about

private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = dialog.getWindow();
    window.setGravity(Gravity.CENTER);

    window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    dialog.setTitle(null);
    dialog.setContentView(R.layout.selectpic_dialog);
    dialog.setCancelable(true);

    dialog.show();
}

you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment

It depends on what you are comparing to None. Some classes have custom comparison methods that treat == None differently from is None.

In particular the output of a == None does not even have to be boolean !! - a frequent cause of bugs.

For a specific example take a numpy array where the == comparison is implemented elementwise:

import numpy as np
a = np.zeros(3) # now a is array([0., 0., 0.])
a == None #compares elementwise, outputs array([False, False, False]), i.e. not boolean!!!
a is None #compares object to object, outputs False

For other types, check out the types module:

>>> import types
>>> x = "mystring"
>>> isinstance(x, types.StringType)
True
>>> x = 5
>>> isinstance(x, types.IntType)
True
>>> x = None
>>> isinstance(x, types.NoneType)
True

P.S. Typechecking is a bad idea.

 WebElement p= driver.findElement(By.id("your id name"));
 p.sendKeys(Keys.chord(Keys.CONTROL, "a"), "55");

You should be strongly typing your views. Then you can do this:

public class YourViewModel {
    public bool ConditionaValue { get; set; }
}

In your view, you can create a checkbox that will bind to this boolean value:

@Html.CheckBoxFor(x => x.ConditionalValue)

If it is checked, the model property will be true.

For your immediate problem though.. you need to name your checkbox to be the same name as your action method parameters.. and they should be bool..

While you should probably use one of the many SQLite wrappers, if you wanted to know how to call the SQLite library yourself, you would:

1. Configure your Swift project to handle SQLite C calls. If using Xcode 9 or later, you can simply do:

   import SQLite3
   

2. Create/open database.

   let fileURL = try! FileManager.default
       .url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
       .appendingPathComponent("test.sqlite")
   
   // open database
   
   var db: OpaquePointer?
   guard sqlite3_open(fileURL.path, &db) == SQLITE_OK else {
       print("error opening database")
       sqlite3_close(db)
       db = nil
       return
   }
   

   Note, I know it seems weird to close the database upon failure to open, but the sqlite3_open documentation makes it explicit that we must do so to avoid leaking memory:

   Whether or not an error occurs when it is opened, resources associated with the database connection handle should be released by passing it to sqlite3_close() when it is no longer required.

3. Use sqlite3_exec to perform SQL (e.g. create table).

   if sqlite3_exec(db, "create table if not exists test (id integer primary key autoincrement, name text)", nil, nil, nil) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error creating table: \(errmsg)")
   }
   

4. Use sqlite3_prepare_v2 to prepare SQL with ? placeholder to which we'll bind value.

   var statement: OpaquePointer?
   
   if sqlite3_prepare_v2(db, "insert into test (name) values (?)", -1, &statement, nil) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error preparing insert: \(errmsg)")
   }
   
   if sqlite3_bind_text(statement, 1, "foo", -1, SQLITE_TRANSIENT) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("failure binding foo: \(errmsg)")
   }
   
   if sqlite3_step(statement) != SQLITE_DONE {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("failure inserting foo: \(errmsg)")
   }
   

   Note, that uses the SQLITE_TRANSIENT constant which can be implemented as follows:

   internal let SQLITE_STATIC = unsafeBitCast(0, to: sqlite3_destructor_type.self)
   internal let SQLITE_TRANSIENT = unsafeBitCast(-1, to: sqlite3_destructor_type.self)
   

5. Reset SQL to insert another value. In this example, I'll insert a NULL value:

   if sqlite3_reset(statement) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error resetting prepared statement: \(errmsg)")
   }
   
   if sqlite3_bind_null(statement, 1) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("failure binding null: \(errmsg)")
   }
   
   if sqlite3_step(statement) != SQLITE_DONE {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("failure inserting null: \(errmsg)")
   }
   

6. Finalize prepared statement to recover memory associated with that prepared statement:

   if sqlite3_finalize(statement) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error finalizing prepared statement: \(errmsg)")
   }
   
   statement = nil
   

7. Prepare new statement for selecting values from table and loop through retrieving the values:

   if sqlite3_prepare_v2(db, "select id, name from test", -1, &statement, nil) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error preparing select: \(errmsg)")
   }
   
   while sqlite3_step(statement) == SQLITE_ROW {
       let id = sqlite3_column_int64(statement, 0)
       print("id = \(id); ", terminator: "")
   
       if let cString = sqlite3_column_text(statement, 1) {
           let name = String(cString: cString)
           print("name = \(name)")
       } else {
           print("name not found")
       }
   }
   
   if sqlite3_finalize(statement) != SQLITE_OK {
       let errmsg = String(cString: sqlite3_errmsg(db)!)
       print("error finalizing prepared statement: \(errmsg)")
   }
   
   statement = nil
   

8. Close database:

   if sqlite3_close(db) != SQLITE_OK {
       print("error closing database")
   }
   
   db = nil
   

For Swift 2 and older versions of Xcode, see previous revisions of this answer.

You can simply reverse a Linked List using only one Extra pointer. And the key to do this is by using a Recursion.

Here is the program in Java.

public class Node {
   public int data;
   public Node next;
}

public Node reverseLinkedListRecursion(Node p) {
    if (p.next == null) {
        head = p;
        q = p;
        return q;
    } else {
        reverseLinkedListRecursion(p.next);
        p.next = null;
        q.next = p;
        q = p;
        return head;
    }
}

// call this function from your main method.
 reverseLinkedListRecursion(head);

As you can see this is a simple example of a head recursion. We have mainly two different kinds of Recursion.

1. Head Recursion:- When the Recursion is the first thing executed by a function.
2. Tail Recursion:- When the Recursion is the last thing executed by a function.

Here the program will keep calling itself Recursively until our Pointer "p" reaches to the last node and then before returning the stack frame we will point head to the last node and the extra Pointer "q" to build the linked list in the backward direction.

Here the Stack Frames will keep on returning until the stack is empty.

Some numpy functions for how to control the rounding: rint, floor,trunc, ceil. depending how u wish to round the floats, up, down, or to the nearest int.

>>> x = np.array([[1.0,2.3],[1.3,2.9]])
>>> x
array([[ 1. ,  2.3],
       [ 1.3,  2.9]])
>>> y = np.trunc(x)
>>> y
array([[ 1.,  2.],
       [ 1.,  2.]])
>>> z = np.ceil(x)
>>> z
array([[ 1.,  3.],
       [ 2.,  3.]])
>>> t = np.floor(x)
>>> t
array([[ 1.,  2.],
       [ 1.,  2.]])
>>> a = np.rint(x)
>>> a
array([[ 1.,  2.],
       [ 1.,  3.]])

To make one of this in to int, or one of the other types in numpy, astype (as answered by BrenBern):

a.astype(int)
array([[1, 2],
       [1, 3]])

>>> y.astype(int)
array([[1, 2],
       [1, 2]])

Well (a long one) ... if you insist to have $scope access inside a service, you can:

Create a getter/setter service

ngapp.factory('Scopes', function (){
  var mem = {};
  return {
    store: function (key, value) { mem[key] = value; },
    get: function (key) { return mem[key]; }
  };
});

Inject it and store the controller scope in it

ngapp.controller('myCtrl', ['$scope', 'Scopes', function($scope, Scopes) {
  Scopes.store('myCtrl', $scope);
}]);

Now, get the scope inside another service

ngapp.factory('getRoute', ['Scopes', '$http', function(Scopes, $http){
  // there you are
  var $scope = Scopes.get('myCtrl');
}]);

if (cast('2012-06-20 23:49:14.363' as time) between 
    cast('2012-06-20 23:49:14.363' as time) and 
    cast('2012-06-20 23:49:14.363' as time))

useTimezone is an older workaround. MySQL team rewrote the setTimestamp/getTimestamp code fairly recently, but it will only be enabled if you set the connection parameter useLegacyDatetimeCode=false and you're using the latest version of mysql JDBC connector. So for example:

String url =
 "jdbc:mysql://localhost/mydb?useLegacyDatetimeCode=false

If you download the mysql-connector source code and look at setTimestamp, it's very easy to see what's happening:

If use legacy date time code = false, newSetTimestampInternal(...) is called. Then, if the Calendar passed to newSetTimestampInternal is NULL, your date object is formatted in the database's time zone:

this.tsdf = new SimpleDateFormat("''yyyy-MM-dd HH:mm:ss", Locale.US);
this.tsdf.setTimeZone(this.connection.getServerTimezoneTZ());
timestampString = this.tsdf.format(x);

It's very important that Calendar is null - so make sure you're using:

setTimestamp(int,Timestamp).

... NOT setTimestamp(int,Timestamp,Calendar).

It should be obvious now how this works. If you construct a date: January 5, 2011 3:00 AM in America/Los_Angeles (or whatever time zone you want) using java.util.Calendar and call setTimestamp(1, myDate), then it will take your date, use SimpleDateFormat to format it in the database time zone. So if your DB is in America/New_York, it will construct the String '2011-01-05 6:00:00' to be inserted (since NY is ahead of LA by 3 hours).

To retrieve the date, use getTimestamp(int) (without the Calendar). Once again it will use the database time zone to build a date.

Note: The webserver time zone is completely irrelevant now! If you don't set useLegacyDatetimecode to false, the webserver time zone is used for formatting - adding lots of confusion.

Note:

It's possible MySQL my complain that the server time zone is ambiguous. For example, if your database is set to use EST, there might be several possible EST time zones in Java, so you can clarify this for mysql-connector by telling it exactly what the database time zone is:

String url =
 "jdbc:mysql://localhost/mydb?useLegacyDatetimeCode=false&serverTimezone=America/New_York";

You only need to do this if it complains.

This way a token will exist up-to 24 hours. here is the code to generate token which will valid up-to 24 Hours. this code we use but i did not compose it.

public static string GenerateToken()
{
    int month = DateTime.Now.Month;
    int day = DateTime.Now.Day;
    string token = ((day * 100 + month) * 700 + day * 13).ToString();
    return token;
}

You're trying to access a JSON, not JSONP.

Notice the difference between your source:

https://api.flightstats.com/flex/schedules/rest/v1/json/flight/AA/100/departing/2013/10/4?appId=19d57e69&appKey=e0ea60854c1205af43fd7b1203005d59&callback=?

And actual JSONP (a wrapping function):

http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=processJSON&tags=monkey&tagmode=any&format=json

Search for JSON + CORS/Cross-domain policy and you will find hundreds of SO threads on this very topic.

In the UK, there are a few government standards which deal successfully with the bulk of the UK population -- the Passport Office, the Driver & Vehicle Licensing Agency, the Deed Poll office, and the NHS. They use different standards, obviously.

Changing your name by Deed Poll allows 300 characters;

There is no legal limit on the length of your name, but we impose a limit of 300 characters (including spaces) for your full name.

The NHS uses 70 characters for patient names

PATIENT NAME
Format/length: max an70

The Passport Office allows 30+30 first/last and Driving Licenses (DVLA) is 30 total.

Note that other organisations will have their own restrictions about what they will show on the documents they produce — for HM Passport Office the limit is 30 characters each for your forename and your surname, and for the DVLA the limit is 30 characters in total for your full name.

Look at SELECT INTO. This will create a new table for you, which can be temporary if you want by prefixing the table name with a pound sign (#).

For example, you can do:

SELECT * 
INTO #YourTempTable
FROM YourReportQuery

For cleaning Immediate window I use (VBA Excel 2016) next function:

Private Sub ClrImmediate()
   With Application.VBE.Windows("Immediate")
       .SetFocus
       Application.SendKeys "^g", True
       Application.SendKeys "^a", True
       Application.SendKeys "{DEL}", True
   End With
End Sub

But direct call of ClrImmediate() like this:

Sub ShowCommandBarNames()
    ClrImmediate
 '--   DoEvents    
    Debug.Print "next..."
End Sub

works only if i put the breakpoint on Debug.Print, otherwise the clearing will be done after execution of ShowCommandBarNames() - NOT before Debug.Print. Unfortunately, call of DoEvents() did not help me... And no matter: TRUE or FALSE is set for SendKeys.

To solve this I use next couple of calls:

Sub ShowCommandBarNames()
 '--    ClrImmediate
    Debug.Print "next..."
End Sub

Sub start_ShowCommandBarNames()
   ClrImmediate
   Application.OnTime Now + TimeSerial(0, 0, 1), "ShowCommandBarNames"
End Sub

It seems to me that using Application.OnTime might be very useful in programming for VBA IDE. In this case it's can be used even TimeSerial(0, 0, 0).

This is common problem for asterisk and this works for me

sudo su
/etc/init.d/asterisk start 
asterisk -rvvv

If not working stop it

sudo su
/etc/init.d/asterisk stop

Start it again

sudo su
/etc/init.d/asterisk start 
asterisk -rvvv

That is all

If the array is NSArray you can use the adding function to add any object at the end of the array, like this:

Swift 4.2

var myArray: NSArray = []
let firstElement: String = "First element"
let secondElement: String = "Second element"

// Process to add the elements to the array
myArray.adding(firstElement)
myArray.adding(secondElement)

Result:

print(myArray) 
// ["First element", "Second element"]

That is a very simple way, regards!

you can also use:

SELECT CASE
         WHEN upper(t.name) like 'P%' THEN
          'productive'
         WHEN upper(t.name) like 'T%' THEN
          'test'
         WHEN upper(t.name) like 'D%' THEN
          'development'
         ELSE
          'unknown'
       END as type
FROM table t

You need to have a look at The Liskov Substitution Principle in Uncle Bob's SOLID principles of class design. :)

ElementTree is a good module for reading xml and writing too e.g.

from xml.etree.ElementTree import Element, SubElement, tostring

root = Element('root')
child = SubElement(root, "child")
child.text = "I am a child"

print(tostring(root))

Output:

<root><child>I am a child</child></root>

See this tutorial for more details and how to pretty print.

Alternatively if your XML is simple, do not underestimate the power of string formatting :)

xmlTemplate = """<root>
    <person>
        <name>%(name)s</name>
        <address>%(address)s</address>
     </person>
</root>"""

data = {'name':'anurag', 'address':'Pune, india'}
print xmlTemplate%data

Output:

<root>
    <person>
        <name>anurag</name>
        <address>Pune, india</address>
     </person>
</root>

You can use string.Template or some template engine too, for complex formatting.

Your ProcExit label is your place where you release all the resources whether an error happened or not. For instance:

Public Sub SubA()
  On Error Goto ProcError

  Connection.Open
  Open File for Writing
  SomePreciousResource.GrabIt

ProcExit:  
  Connection.Close
  Connection = Nothing
  Close File
  SomePreciousResource.Release

  Exit Sub

ProcError:  
  MsgBox Err.Description  
  Resume ProcExit
End Sub

For a web application, to get the current web application root directory, generally call by web page for the current incoming request:

HttpContext.Current.Server.MapPath();

System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath;

Above code description

Taken from the NSString reference, you can use :

NSString *theFileName = [[string lastPathComponent] stringByDeletingPathExtension];

The lastPathComponent call will return thefile.ext, and the stringByDeletingPathExtension will remove the extension suffix from the end.

It is the "not equal" operator, i.e. the equivalent of != in pretty much every other language.

You can use the .ToList() method to convert the IQueryable result returned to an IList, as shown below, after the linq query.

   public DzieckoAndOpiekunCollection GetChildAndOpiekunByFirstnameLastname(string firstname, string lastname)
{
    DataTransfer.ChargeInSchoolEntities db = new DataTransfer.ChargeInSchoolEntities();
    DzieckoAndOpiekunCollection result = new DzieckoAndOpiekunCollection();
    if (firstname == null && lastname != null)
    {
        IList<DzieckoAndOpiekun> resultV = from p in db.Dziecko
                      where lastname == p.Nazwisko
                      **select** new DzieckoAndOpiekun(
                     p.Imie,
                     p.Nazwisko,
                     p.Opiekun.Imie,
                     p.Opiekun.Nazwisko).ToList()
                  ;
        result.AddRange(resultV);
    }
    return result;
}

You can use pcntl_fork() to achieve something similar to threads. Technically it's separate processes, so the communication between the two is not as simple with threads, and I believe it will not work if PHP is called by apache.

The "normal" way is to:

• Go to the Beautiful Soup web site, http://www.crummy.com/software/BeautifulSoup/
• Download the package
• Unpack it
• In a Terminal window, cd to the resulting directory
• Type python setup.py install

Another solution is to use easy_install. Go to http://peak.telecommunity.com/DevCenter/EasyInstall), install the package using the instructions on that page, and then type, in a Terminal window:

easy_install BeautifulSoup4
# for older v3:
# easy_install BeautifulSoup

easy_install will take care of downloading, unpacking, building, and installing the package. The advantage to using easy_install is that it knows how to search for many different Python packages, because it queries the PyPI registry. Thus, once you have easy_install on your machine, you install many, many different third-party packages simply by one command at a shell.

we mainly use the markup notation of jquery validation plugin and the posted samples did not work for us, when flags are present in the regex, e.g.

<input type="text" name="myfield" regex="/^[0-9]{3}$/i" />

therefore we use the following snippet

$.validator.addMethod(
        "regex",
        function(value, element, regstring) {
            // fast exit on empty optional
            if (this.optional(element)) {
                return true;
            }

            var regParts = regstring.match(/^\/(.*?)\/([gim]*)$/);
            if (regParts) {
                // the parsed pattern had delimiters and modifiers. handle them. 
                var regexp = new RegExp(regParts[1], regParts[2]);
            } else {
                // we got pattern string without delimiters
                var regexp = new RegExp(regstring);
            }

            return regexp.test(value);
        },
        "Please check your input."
);  

Of course now one could combine this code, with one of the above to also allow passing RegExp objects into the plugin, but since we didn't needed it we left this exercise for the reader ;-).

PS: there is also bundled plugin for that, https://github.com/jzaefferer/jquery-validation/blob/master/src/additional/pattern.js

else:
    print("System " + ip + " is DOWN !")

I can see great answers, so there's no need to repeat here, so I'd like to offer some advice:

I would recommend using a Unix Timestamp integer instead of a human-readable date format to handle time internally, then use PHP's date() function to convert the timestamp value into a human-readable date format for user display. Here's a crude example of how it should be done:

// Get unix timestamp in seconds
$current_time = date();

// Or if you need millisecond precision

// Get unix timestamp in milliseconds
$current_time = microtime(true);

Then use $current_time as needed in your app (store, add or subtract, etc), then when you need to display the date value it to your users, you can use date() to specify your desired date format:

// Display a human-readable date format
echo date('d-m-Y', $current_time);

This way you'll avoid much headache dealing with date formats, conversions and timezones, as your dates will be in a standardized format (Unix Timestamp) that is compact, timezone-independent (always in UTC) and widely supported in programming languages and databases.

While the answer given by Paul H shows the essential part, it is not a complete example. On the other hand the matplotlib example seems rather complicated and does not show how to use days.

So for everyone in need here is a full working example:

from datetime import datetime
import matplotlib.pyplot as plt
from matplotlib.dates import DateFormatter

myDates = [datetime(2012,1,i+3) for i in range(10)]
myValues = [5,6,4,3,7,8,1,2,5,4]
fig, ax = plt.subplots()
ax.plot(myDates,myValues)

myFmt = DateFormatter("%d")
ax.xaxis.set_major_formatter(myFmt)

## Rotate date labels automatically
fig.autofmt_xdate()
plt.show()

A corresponding cross for ✓ ✓ would be ✗ ✗ I think (Dingbats).

The standard approach is to give the centered element fixed dimensions, and place it absolutely:

<div class='fullscreenDiv'>
    <div class="center">Hello World</div>
</div>?

.center {
    position: absolute;
    width: 100px;
    height: 50px;
    top: 50%;
    left: 50%;
    margin-left: -50px; /* margin is -0.5 * dimension */
    margin-top: -25px; 
}?

• DEMO

To put it nice and simply, get(int index) returns the element at the specified index.

So say we had an ArrayList of Strings:

List<String> names = new ArrayList<String>();
names.add("Arthur Dent");
names.add("Marvin");
names.add("Trillian");
names.add("Ford Prefect");

Which can be visualised as: Where 0, 1, 2, and 3 denote the indexes of the ArrayList.

Say we wanted to retrieve one of the names we would do the following: String name = names.get(1); Which returns the name at the index of 1.

So if we were to print out the name System.out.println(name); the output would be Marvin - Although he might not be too happy with us disturbing him.

Netscape ANSI encoded files use 0D 0D 0A for their line breaks.

In ES2015 a.k.a ES6 version of JavaScript, a new datatype called Map is introduced.

let map = new Map([["key1", "value1"], ["key2", "value2"]]);
map.get("key1"); // => value1

Came here looking for an answer to this question myself. The slice answer is probably best, but I went ahead and created a "last" function just to practice extending prototypes, so I thought I would go ahead and share it. It has the added benefit over some other ones of letting you optionally count backwards through the array, and pull out, say, the second to last or third to last item. If you don't specify a count it just defaults to 1 and pulls out the last item.

Array.prototype.last = Array.prototype.last || function(count) {
    count = count || 1;
    var length = this.length;
    if (count <= length) {
        return this[length - count];
    } else {
        return null;
    }
};

var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];
arr.last(); // returns 9
arr.last(4); // returns 6
arr.last(9); // returns 1
arr.last(10); // returns null

It seems things have changed around a bit in the latest version of react router. You can now access history via the context. this.context.history.push('/path')

Although systemd indeed does not provide way to pass command-line arguments for unit files, there are possibilities to write instances: http://0pointer.de/blog/projects/instances.html

For example: /lib/systemd/system/[email protected] looks something like this:

[Unit]
Description=Serial Getty on %I
BindTo=dev-%i.device
After=dev-%i.device systemd-user-sessions.service

[Service]
ExecStart=-/sbin/agetty -s %I 115200,38400,9600
Restart=always
RestartSec=0

So, you may start it like:

$ systemctl start [email protected]
$ systemctl start [email protected]

For systemd it will different instances:

$ systemctl status [email protected]
[email protected] - Getty on ttyUSB0
      Loaded: loaded (/lib/systemd/system/[email protected]; static)
      Active: active (running) since Mon, 26 Sep 2011 04:20:44 +0200; 2s ago
    Main PID: 5443 (agetty)
      CGroup: name=systemd:/system/[email protected]/ttyUSB0
          + 5443 /sbin/agetty -s ttyUSB0 115200,38400,9600

It also mean great possibility enable and disable it separately.

Off course it lack much power of command line parsing, but in common way it is used as some sort of config files selection. For example you may look at Fedora [email protected]: http://pkgs.fedoraproject.org/cgit/openvpn.git/tree/[email protected]

Revised Answer

If you're not calling this code from another program, an option is to skip PL/SQL and do it strictly in SQL using bind variables:

var myname varchar2(20);

exec :myname := 'Tom';

SELECT *
FROM   Customers
WHERE  Name = :myname;

In many tools (such as Toad and SQL Developer), omitting the var and exec statements will cause the program to prompt you for the value.

Original Answer

A big difference between T-SQL and PL/SQL is that Oracle doesn't let you implicitly return the result of a query. The result always has to be explicitly returned in some fashion. The simplest way is to use DBMS_OUTPUT (roughly equivalent to print) to output the variable:

DECLARE
   myname varchar2(20);
BEGIN
     myname := 'Tom';

     dbms_output.print_line(myname);
END;

This isn't terribly helpful if you're trying to return a result set, however. In that case, you'll either want to return a collection or a refcursor. However, using either of those solutions would require wrapping your code in a function or procedure and running the function/procedure from something that's capable of consuming the results. A function that worked in this way might look something like this:

CREATE FUNCTION my_function (myname in varchar2)
     my_refcursor out sys_refcursor
BEGIN
     open my_refcursor for
     SELECT *
     FROM   Customers
     WHERE  Name = myname;

     return my_refcursor;
END my_function;

I find it easiest (and most readable) to just copy the line and comment out the original version:

#Old version of ls:
#ls -l $([ ] && -F is turned off) -a /etc
ls -l -a /etc

In PHP >= 5.4.0 there is a new interface for serializing objects to JSON : JsonSerializable

Just implement the interface in your object and define a JsonSerializable method which will be called when you use json_encode.

So the solution for PHP >= 5.4.0 should look something like this:

class JsonObject implements JsonSerializable
{
    // properties

    // function called when encoded with json_encode
    public function jsonSerialize()
    {
        return get_object_vars($this);
    }
}

AFAIK you will need at least a little bit of JavaScript...

I would suggest to use jQuery.

You can include this library in one line. And then you can access your div with

$('div').click(function(){
  // do stuff here
});

and respond to the click event.

Also you can use DownloadFileAsync method in WebClient class. It downloads to a local file the resource with the specified URI. Also this method does not block the calling thread.

Sample:

    webClient.DownloadFileAsync(new Uri("http://www.example.com/file/test.jpg"), "test.jpg");

Follow download wizard

Follow the screens one by one to select type of package (curl executable), OS (Win64), flavor (Generic), CPU (x86_64) and the download link.

unzip download and find curl.exe (I found it in src folder, one may find it in bin folder for different OS/flavor)

To make it available from the command line, add the executable path to the system path (Adding directory to PATH Environment Variable in Windows).

Enjoy curl.
