REST based Services/Architecture vs. RESTFUL Services/Architecture

To differentiate or compare these 2, you should know what REST is.

REST (REpresentational State Transfer) is basically an architectural style of development having some principles:

• It should be stateless

• It should access all the resources from the server using only URI

• It does not have inbuilt encryption

• It does not have session

• It uses one and only one protocol - HTTP

• For performing CRUD operations, it should use HTTP verbs such as get, post, put and delete

• It should return the result only in the form of JSON or XML, atom, OData etc. (lightweight data )

REST based services follow some of the above principles and not all

RESTFUL services means it follows all the above principles.

It is similar to the concept of:

Object oriented languages support all the OOP concepts, examples: C++, C#

Object-based languages support some of the OOP features, examples: JavaScript, VB

Example:

ASP Dot NET MVC 4 is REST-Based while Microsoft WEB API is RESTFul.

MVC supports only some of the above REST principles whereas WEB API supports all the above REST Principles.

MVC only supports the following from the REST API

• We can access the resource using URI

• It supports the HTTP verb to access the resource from server

• It can return the results in the form of JSON, XML, that is the HTTPResponse.

However, at the same time in MVC

• We can use the session

• We can make it stateful

• We can return video or image from the controller action method which basically violates the REST principles

That is why MVC is REST-Based whereas WEB API supports all the above principles and is RESTFul.

I just had to uncomment the line in jboss-eap-5.0\jboss-as\server\default\conf\props\jmx-console-users.properties

admin=admin

Thats it. Restart Jboss and I was about to get in to JBOSS JMX. Magically this even fixed the error that I used to get while shutting down Jboss from Eclipse.

The first function in an m-file (i.e. the main function), is invoked when that m-file is called. It is not required that the main function have the same name as the m-file, but for clarity it should. When the function and file name differ, the file name must be used to call the main function.

All subsequent functions in the m-file, called local functions (or "subfunctions" in the older terminology), can only be called by the main function and other local functions in that m-file. Functions in other m-files can not call them. Starting in R2016b, you can add local functions to scripts as well, although the scoping behavior is still the same (i.e. they can only be called from within the script).

In addition, you can also declare functions within other functions. These are called nested functions, and these can only be called from within the function they are nested. They can also have access to variables in functions in which they are nested, which makes them quite useful albeit slightly tricky to work with.

More food for thought...

There are some ways around the normal function scoping behavior outlined above, such as passing function handles as output arguments as mentioned in the answers from SCFrench and Jonas (which, starting in R2013b, is facilitated by the localfunctions function). However, I wouldn't suggest making it a habit of resorting to such tricks, as there are likely much better options for organizing your functions and files.

For example, let's say you have a main function A in an m-file A.m, along with local functions D, E, and F. Now let's say you have two other related functions B and C in m-files B.m and C.m, respectively, that you also want to be able to call D, E, and F. Here are some options you have:

• Put D, E, and F each in their own separate m-files, allowing any other function to call them. The downside is that the scope of these functions is large and isn't restricted to just A, B, and C, but the upside is that this is quite simple.

• Create a defineMyFunctions m-file (like in Jonas' example) with D, E, and F as local functions and a main function that simply returns function handles to them. This allows you to keep D, E, and F in the same file, but it doesn't do anything regarding the scope of these functions since any function that can call defineMyFunctions can invoke them. You also then have to worry about passing the function handles around as arguments to make sure you have them where you need them.

• Copy D, E and F into B.m and C.m as local functions. This limits the scope of their usage to just A, B, and C, but makes updating and maintenance of your code a nightmare because you have three copies of the same code in different places.

• Use private functions! If you have A, B, and C in the same directory, you can create a subdirectory called private and place D, E, and F in there, each as a separate m-file. This limits their scope so they can only be called by functions in the directory immediately above (i.e. A, B, and C) and keeps them together in the same place (but still different m-files):

  myDirectory/
      A.m
      B.m
      C.m
      private/
          D.m
          E.m
          F.m
  

All this goes somewhat outside the scope of your question, and is probably more detail than you need, but I thought it might be good to touch upon the more general concern of organizing all of your m-files. ;)

Try this

SELECT Count(*) AS N
FROM
(SELECT DISTINCT Name FROM table1) AS T;

setGame has been discontinued. You must use client.user.setActivity.

Don't forget, if you are setting a streaming status, you MUST specify a Twitch URL

An example is here:

client.user.setActivity("with depression", {
  type: "STREAMING",
  url: "https://www.twitch.tv/example-url"
});

You have an option to define collation order at the time of defining your table. If you define a case-sensitive order, your LIKE operator will behave in a case-sensitive way; if you define a case-insensitive collation order, the LIKE operator will ignore character case as well:

CREATE TABLE Test (
    CI_Str VARCHAR(15) COLLATE Latin1_General_CI_AS -- Case-insensitive
,   CS_Str VARCHAR(15) COLLATE Latin1_General_CS_AS -- Case-sensitive
);

Here is a quick demo on sqlfiddle showing the results of collation order on searches with LIKE.

It's not a truly new answer, but - when using img2pdf the page size didn't come out right. So here's what I did to use the image size, I hope it finds someone well:

assuming 1) all images are the same size, 2) placing one image per page, 3) image fills the whole page

from PIL import Image
import img2pdf

with open( 'output.pdf', 'wb' ) as f:
    img = Image.open( '1.jpg' )
    my_layout_fun = img2pdf.get_layout_fun(
        pagesize = ( img2pdf.px_to_pt( img.width, 96 ), img2pdf.px_to_pt( img.height, 96 ) ), # this is where image size is used; 96 is dpi value
        fit = img2pdf.FitMode.into # I didn't have to specify this, but just in case...
    )
    f.write( img2pdf.convert( [ '1.jpg', '2.jpg', '3.jpg' ], layout_fun = my_layout_fun ))

Ad hoc queries are those that are not already defined that are not needed on a regular basis, so they're not included in the typical set of reports or queries

Other solution:

def round_time(timestamp=None, lapse=0):
    """
    Round a timestamp to a lapse according to specified minutes

    Usage:

    >>> import datetime, math
    >>> round_time(datetime.datetime(2010, 6, 10, 3, 56, 23), 0)
    datetime.datetime(2010, 6, 10, 3, 56)
    >>> round_time(datetime.datetime(2010, 6, 10, 3, 56, 23), 1)
    datetime.datetime(2010, 6, 10, 3, 57)
    >>> round_time(datetime.datetime(2010, 6, 10, 3, 56, 23), -1)
    datetime.datetime(2010, 6, 10, 3, 55)
    >>> round_time(datetime.datetime(2019, 3, 11, 9, 22, 11), 3)
    datetime.datetime(2019, 3, 11, 9, 24)
    >>> round_time(datetime.datetime(2019, 3, 11, 9, 22, 11), 3*60)
    datetime.datetime(2019, 3, 11, 12, 0)
    >>> round_time(datetime.datetime(2019, 3, 11, 10, 0, 0), 3)
    datetime.datetime(2019, 3, 11, 10, 0)

    :param timestamp: Timestamp to round (default: now)
    :param lapse: Lapse to round in minutes (default: 0)
    """
    t = timestamp or datetime.datetime.now()  # type: Union[datetime, Any]
    surplus = datetime.timedelta(seconds=t.second, microseconds=t.microsecond)
    t -= surplus
    try:
        mod = t.minute % lapse
    except ZeroDivisionError:
        return t
    if mod:  # minutes % lapse != 0
        t += datetime.timedelta(minutes=math.ceil(t.minute / lapse) * lapse - t.minute)
    elif surplus != datetime.timedelta() or lapse < 0:
        t += datetime.timedelta(minutes=(t.minute / lapse + 1) * lapse - t.minute)
    return t

Hope this helps!

Threading is another possible solution. Although the Celery based solution is better for applications at scale, if you are not expecting too much traffic on the endpoint in question, threading is a viable alternative.

This solution is based on Miguel Grinberg's PyCon 2016 Flask at Scale presentation, specifically slide 41 in his slide deck. His code is also available on github for those interested in the original source.

From a user perspective the code works as follows:

1. You make a call to the endpoint that performs the long running task.
2. This endpoint returns 202 Accepted with a link to check on the task status.
3. Calls to the status link returns 202 while the taks is still running, and returns 200 (and the result) when the task is complete.

To convert an api call to a background task, simply add the @async_api decorator.

Here is a fully contained example:

from flask import Flask, g, abort, current_app, request, url_for
from werkzeug.exceptions import HTTPException, InternalServerError
from flask_restful import Resource, Api
from datetime import datetime
from functools import wraps

tasks = {}

    def clean_old_tasks():
        """
        This function cleans up old tasks from our in-memory data structure.
        """
        global tasks
        while True:
            # Only keep tasks that are running or that finished less than 5
            # minutes ago.
            five_min_ago = datetime.timestamp(datetime.utcnow()) - 5 * 60
            tasks = {task_id: task for task_id, task in tasks.items()
                     if 'completion_timestamp' not in task or task['completion_timestamp'] > five_min_ago}
            time.sleep(60)

As per the official installation page of skimage (skimage Installation) : python-skimage package depends on matplotlib, scipy, pil, numpy and six.

So install them first using

sudo apt-get install python-matplotlib python-numpy python-pil python-scipy

Apparently skimage is a part of Cython which in turn is a superset of python and hence you need to install Cython to be able to use skimage.

sudo apt-get install build-essential cython

Now install skimage package using

sudo apt-get install python-skimage

This solved the Import error for me.

I ran into this error sporadically and could not understand. Googling did not help.

I finally found out. I run a couple of docker containers, among them NGINX and Apache. The command at hand addresses a specific container, running Apache. As it turned out, I also have a cron job doing some heavy lifting at times running on the same container. Depending on the load this cron job puts on this container, it was not able to answer my command in a timely manner, resulting in error 52 empty reply from server or even 502 Bad Gateway.

I discovered and verified this by plain curl when I noticed that the process I investigated took less than 2 seconds and all of a sudden I got a 52 error and then a 502 error and then again less than 2 seconds - so it was definitely not my code which was unchanged. Using ps aux within the container I saw the other process running and understood.

Actually, I was bothered by 502 Bad Gateway from NGINX with long running jobs and could not fix it with the appropriate parameters, so I finally gave up and switched these things to Apache. That's why I was puzzled even more about these errors.

The remedy is simple. I just fired up some more instances of this container with docker service scale and that was it. docker load balances on its own.

Well, there is more to this as another example showed. This time I did some repetitious jobs.

I found out that after some time I ran out of memory used by PHP which cannot be reclaimed, so the process died.

Why? Having more than a dozen containers on a 8GB RAM machine, I initially thought it would be a good idea to limit RAM usage on PHP containers to 50MB.

Stupid! I forgot about it, but swarmpit gave me a hint. I call ini_set("memory_limit",-1); in the constructor of my class, but that only went as far as those 50MB.

So I removed those restrictions from my compose file. Now those containers may use up to 8GB. The process runs with Apache for hours now and it looks like the problem is solved, memory usage rising to well beyond 100MB.

Another caveat: To easily get and read debug messages, I started said process in Opera under Windows. That is fine with errors appearing soon.

However, if the last one is cared for, quite naturally the process runs and runs and memory usage in the browser builds up, eventually making my local machine unusable. So if that happens, kill this tab and the process keeps running fine.

You don't have to call the external basename command. Instead, you could use the following commands:

$ s=/the/path/foo.txt
$ echo "${s##*/}"
foo.txt
$ s=${s##*/}
$ echo "${s%.txt}"
foo
$ echo "${s%.*}"
foo

Note that this solution should work in all recent (post 2004) POSIX compliant shells, (e.g. bash, dash, ksh, etc.).

This is specific to Windows. I was facing the same issue where I have to kill one specific java program using taskkill. When I run the java program, tasklist was showing the same program with Image name set as java.exe. But killing it using taskkill /F java.exe will stop all other java applications other than intended one which is not required.

So I run the same java program using:

start "MyProgramName" java java-program..

Here start command will open a new window and run the java program with window's title set to MyProgramName.

Now to kill this java-program use the following taskkill command:

taskkill /fi "MyProgramName"

Your Java program will be killed only. Rest will be unaffected.

If you are using swift4 and Alamofire v4.0 then the accepted code would look like this :

            let parameters: Parameters = [ "username" : email.text!, "password" : password.text! ]
            let urlString = "https://api.harridev.com/api/v1/login"
            let url = URL.init(string: urlString)
            Alamofire.request(url!, method: .put, parameters: parameters, encoding: JSONEncoding.default, headers: nil).responseJSON { response in
                 switch response.result

                case .success(let json):
                    let jsonData = json as! Any

Does anyone know how to get sed to print the position of the illegal byte sequence? Or does anyone know what the illegal byte sequence is?

I got part of the way to answering the above just by using tr.

I have a .csv file that is a credit card statement and I am trying to import it into Gnucash. I am based in Switzerland so I have to deal with words like Zürich. Suspecting Gnucash does not like " " in numeric fields, I decide to simply replace all

; ;

with

;;

Here goes:

$ head -3 Auswertungen.csv | tail -1 | sed -e 's/; ;/;;/g'
sed: RE error: illegal byte sequence

I used od to shed some light: Note the 374 halfway down this od -c output

$ head -3 Auswertungen.csv | tail -1 | od -c

Then I thought I might try to persuade tr to substitute 374 for whatever the correct byte code is. So first I tried something simple, which didn't work, but had the side effect of showing me where the troublesome byte was:

$ head -3 Auswertungen.csv | tail -1 | tr . .  ; echo
tr: Illegal byte sequence
1687 9619 7122;5468 87XX XXXX 2660;MY NAME ISX;14.02.2019;9552 - Mitarbeiterrest   Z

You can see tr bails at the 374 character.

Using perl seems to avoid this problem

$ head -3 Auswertungen.csv | tail -1 | perl -pne 's/; ;/;;/g'
1687 9619 7122;5468 87XX XXXX 2660;ADAM NEALIS;14.02.2019;9552 - Mitarbeiterrest   Z?rich       CHE;Restaurants, Bars;6.20;CHF;;CHF;6.20;;15.02.2019

First represent the epoch of the millisecond time as a date (usually 1/1/1970), then add your millisecond time divided by the number of milliseconds in a day (86400000):

=DATE(1970,1,1)+(A1/86400000)

If your cell is properly formatted, you should see a human-readable date/time.

If you're running a *nix system, also consider mytop.

To limit the results to one database, press "d" when it's running then type in the database name.

The viewController has to be a child of UITabBarControllerDelegate. So you just need to add the following code on SWIFT 3

self.tabBarController?.selectedIndex = 1

This topic is well covered already but I wanted to add something more specific : I wanted to be sure that a certain value would be mapped to that color (not to any color).

First of all I wanted to thank jimbo and (his post / twitter-api-php simple library).

If you are going to use the GET search/tweets API with "twitter-api-php" PHP library (TwitterAPIExchange.php):

First, you have to just comment "Perform a POST request and echo the response " code area.

Just use "Perform a GET request and echo the response" code and echo the response and change these two lines:

$url = 'https://api.twitter.com/1.1/followers/ids.json';
$getfield = '?screen_name=J7mbo';

to

$url = 'https://api.twitter.com/1.1/search/tweets.json';
$getfield = '?q=J7mbo';

(Change screen_name to q, that's it :)

In my case both node and npm were in same path (/usr/bin). The NODE_PATH was empty, so the npm placed the global modules into /usr/lib/node_modules where require(...) successfully find them. The only exception was the npm module, which came with the nodejs package. Since I'm using 64 bit system, it was placed into /usr/lib64/node_modules. This is not where require(...) searches in case of empty NODE_PATH and node started from /usr/bin. So I had two options:

• link /usr/lib64/node_modules/npm to /usr/lib/node_modules/npm
• move modules from /usr/lib/node_modules/* to /usr/lib64/node_modules/ and set NODE_PATH=/usr/lib64/node_modules

Both worked. I'm using OpenSUSE 42.1 and the nodejs package from updates repository. Version is 4.4.5.

I got the same error ("Uncaught SyntaxError: Unexpected token <" ) at these two lines when testing a sample application .

<script type = "text/javascript"  src="raphael-min.js"></script>
<script type = "text/javascript"  src="kuma-gauge.jquery.js"></script>

After a control, I realized that, local file locations are not correct and my local server app returns default page as the result. Client app can find the files but the founded files are default page, not the *.js files. So I receive Uncaught SyntaxError: Unexpected token <

I changed to orginal location on the intenet andit solved.

<script type = "text/javascript"  src="//cdnjs.cloudflare.com/ajax/libs/raphael/2.1.2/raphael-min.js"></script>
<script type = "text/javascript"  src="//www.jqueryscript.net/demo/Creating-Animated-Gauges-Using-jQuery-Raphael-js-kumaGauge/js/kuma-gauge.jquery.js"></script>

I use hebrew(RTL language) in strings.xml. I have manually searched the string.xml for this char: ' than I added the escape char \ infront of it (now it looks like \' ) and still got the same error!

I searched again for the char ' and I replaced the char ' with \'(eng writing) , since it shows a right to left it looks like that '\ in the strings.xml !!

Problem solved.

You can simply use the jQuery Validate plugin as follows.

jQuery:

$(document).ready(function () {

    $('#myform').validate({ // initialize the plugin
        rules: {
            field1: {
                required: true,
                email: true
            },
            field2: {
                required: true,
                minlength: 5
            }
        }
    });

});

HTML:

<form id="myform">
    <input type="text" name="field1" />
    <input type="text" name="field2" />
    <input type="submit" />
</form>

9.3 Context per request

Entity Framework’s contexts are meant to be used as short-lived instances in order to provide the most optimal performance experience. Contexts are expected to be short lived and discarded, and as such have been implemented to be very lightweight and reutilize metadata whenever possible. In web scenarios it’s important to keep this in mind and not have a context for more than the duration of a single request. Similarly, in non-web scenarios, context should be discarded based on your understanding of the different levels of caching in the Entity Framework. Generally speaking, one should avoid having a context instance throughout the life of the application, as well as contexts per thread and static contexts.

Yay thanks! This too has been driving me nuts forever.

In my particular case, this worked for me:

input {
    width: 13px;
    height: 13px;
    padding: 0;
    margin:0;
    vertical-align: top;
    position: relative;
    *top: 1px;
    *overflow: hidden;
}
label {
    display: block;
    padding: 0;
    padding-left: 15px;
    text-indent: -15px;
    border: 0px solid;
    margin-left: 5px;
    vertical-align: top;
}

I am using the reset.css which might explain some of the differences, but this seems to work well for me.

With JQM 1.4.2 this one works for me (Change theme to the used one):

.ui-page-theme-b, .ui-page-theme-b .ui-panel-wrapper {
    background: transparent url(../img/xxx) !important;
    background-repeat:repeat !important;
}

JohnMachin's comment should be the real answer. All the other answers are just workarounds in my opinion! So:

array=[0]*element_count

I happened that problem on a virtual server, when everything worked correctly on other hosting. After several modifications I realized that I include or require_one works on all calls except in a file. The problem of this file was the code < ?php ? > At the beginning and end of the text. It was a script that was only < ?, and in that version of apache that was running did not work

KooiInc has a good answer to this. To summarise:

String.prototype.trunc = 
      function(n){
          return this.substr(0,n-1)+(this.length>n?'…':'');
      };

Now you can do:

var s = 'not very long';
s.trunc(25); //=> not very long
s.trunc(5); //=> not...

And if you prefer it as a function, as per @AlienLifeForm's comment:

function truncateWithEllipses(text, max) 
{
    return text.substr(0,max-1)+(text.length>max?'…':''); 
}

Full credit goes to KooiInc for this.

Don't ever put an Exit button on an Android app. Let the OS decide when to kill your Activity. Learn about the Android Activity lifecycle and implement any necessary callbacks.

Ummm, How about this.

Copy your cells.
Open Notepad.
Paste.

Look no quotes, no inverted commas, and retains special characters, which is what the OP asked for. Its also delineated by carriage returns, same as the attached pict which the OP didn't mention as a bad thing (or a good thing).

Not really sure why a simple answer, that delivers the desired results, gets me a negative mark.

CSS includes should go in the head before any js script includes. Javascript can go anywhere, but really the function of the file could determine the location. If it builds page content put it on the head. If its used for events or tracking, you can put it before the </body>

In Swift 4.0.3 Xcode 9

============set  Data in UserDefaults =========

  UserDefaults.standard.set(userName, forKey: "userName")
  UserDefaults.standard.synchronize()

============Get Data in UserDefaults =========

  let userName = UserDefaults.standard.string(forKey: "userName")
  print(userName ?? "Gera")

  userNameTextField.text = ""+userName!

Here's another solution that uses some of VBA's built in date functions and stores all the date data in an array for comparison, which may give better performance if you get a lot of data:

Public Sub MoveData(MonthNum As Integer, FromSheet As Worksheet, ToSheet As Worksheet)
    Const DateCol = "A" 'column where dates are store
    Const DestCol = "A" 'destination column where dates are stored. We use this column to find the last populated row in ToSheet
    Const FirstRow = 2 'first row where date data is stored
    'Copy range of values to Dates array
    Dates = FromSheet.Range(DateCol & CStr(FirstRow) & ":" & DateCol & CStr(FromSheet.Range(DateCol & CStr(FromSheet.Rows.Count)).End(xlUp).Row)).Value
    Dim i As Integer
    For i = LBound(Dates) To UBound(Dates)
        If IsDate(Dates(i, 1)) Then
            If Month(CDate(Dates(i, 1))) = MonthNum Then
                Dim CurrRow As Long
                'get the current row number in the worksheet
                CurrRow = FirstRow + i - 1
                Dim DestRow As Long
                'get the destination row
                DestRow = ToSheet.Range(DestCol & CStr(ToSheet.Rows.Count)).End(xlUp).Row + 1
                'copy row CurrRow in FromSheet to row DestRow in ToSheet
                FromSheet.Range(CStr(CurrRow) & ":" & CStr(CurrRow)).Copy ToSheet.Range(DestCol & CStr(DestRow))
            End If
        End If
    Next i
End Sub

Per the current docs, https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html:

If you’re providing text file input to curl, you must use the --data-binary flag instead of plain -d. The latter doesn’t preserve newlines.

Example:

$ curl -s -XPOST localhost:9200/_bulk --data-binary @requests

I tried all the above without success. Eventually I realised I had a weak WiFi connection and therefore slow download speed. I connected my device VIA Ethernet and that solved my problem straight away.

The tail program can do this:

ls -lart | tail -n +2

The -n +2 means “start passing through on the second line of output”.

Anything after the "vmargs" is taken to be vm arguments. Just make sure it's before that, which is the last piece in eclipse.ini.

The following will Return All Procedures in selected database

SELECT * FROM sys.procedures

If you want to restrict valid input to integer values between 1 and 100, this will do it:

^([1-9]|[1-9][0-9]|100)$

Explanation:

1. ^ = start of input
2. () = multiple options to match
3. First argument [1-9] - matches any entries between 1 and 9
4. | = OR argument separator
5. Second Argument [1-9][0-9] - matches entries between 10 and 99
6. Last Argument 100 - Self explanatory - matches entries of 100

This WILL NOT ACCEPT: 1. Zero - 0 2. Any integer preceded with a zero - 01, 021, 001 3. Any integer greater than 100

Hope this helps!

I am not completely sure what you're trying to achieve by seeking to a specific offset and attempting to load individual values manually, the typical usage of the pickle module is:

# save data to a file
with open('myfile.pickle','wb') as fout:
    pickle.dump([1,2,3],fout)

# read data from a file
with open('myfile.pickle') as fin:
    print pickle.load(fin)

# output
>> [1, 2, 3]

If you dumped a list, you'll load a list, there's no need to load each item individually.

you're saying that you got an error before you were seeking to the -5000 offset, maybe the file you're trying to read is corrupted.

If you have access to the original data, I suggest you try saving it to a new file and reading it as in the example.

code:

function writeData() {
    jQuery("#chatTickets input:radio[id^=ticketID]:first").attr('disabled', true);
    return false;
}

See also: Selector/radio, Selector/attributeStartsWith, Selector/first

<input type="button" value="..." onClick="fbLikeDump(); WriteCookie();" />

The static code block can be used to instantiate or initialize class variables (as opposed to object variables). So declaring "a" static means that is only one shared by all Test objects, and the static code block initializes "a" only once, when the Test class is first loaded, no matter how many Test objects are created.

With Xcode 9.3, this seems to be resolved by cleaning the project, quitting and restarting Xcode, and, after the restart, cleaning the build folder (hold Option and select Product->Clean Build Folder).

During the restart I happened to have the Xcode signing-info panel open on the Project navigator and saw a transient message that Xcode was rebuilding the signing profile. Upon trying to run my project on a device, I got a runtime exception due to a Swift framework file having an invalid signature. The second "Clean Build Folder" cleared that up and all works fine now.

Just updated older Ubuntu versions to openJDK 11
Actually I need it for Jenkins only and it seems to work fine.

Ubuntu 12.04 (Precise):
Download from openjdk-lts (11.0.4+11-1~12.04) precise
Files:
openjdk-11-jre-headless_11.0.4+11-1~12.04_amd64.deb
openjdk-11-jre_11.0.4+11-1~12.04_amd64.deb

Ubuntu 14.04 (Trusty):
Download from openjdk-lts (11.0.5+10-2ubuntu1~14.04) trusty
Files:
openjdk-11-jre-headless_11.0.5+10-2ubuntu1_14.04_amd64.deb
openjdk-11-jre_11.0.5+10-2ubuntu1_14.04_amd64.deb

Installation
After download I installed the files with Ubuntu Software Center ("headless" first!)
Then I selected the new version with sudo update-alternatives --config java

I didn't have to change any environment variables (like JAVA_HOME) - maybe Jenkins doesn't care about them...

This isn't as easy to do as one might expect -- you can really only do vertical alignment if you know the height of your container. IF this is the case, you can do it with absolute positioning.

The concept is to set the top / left positions at 50%, and then use negative margins (set to half the height / width) to pull the container back to being centered.

Example: http://jsbin.com/ipawe/edit

Basic CSS:

#mydiv { 
    position: absolute;
    top: 50%;
    left: 50%;
    height: 400px;
    width: 700px;
    margin-top: -200px; /* -(1/2 height) */
    margin-left: -350px; /* -(1/2 width) */
  }

I've run into cases where __file__ doesn't work as expected. But the following hasn't failed me so far:

import inspect
src_file_path = inspect.getfile(lambda: None)

This is the closest thing to a Python analog to C's __FILE__.

The behavior of Python's __file__ is much different than C's __FILE__. The C version will give you the original path of the source file. This is useful in logging errors and knowing which source file has the bug.

Python's __file__ only gives you the name of the currently executing file, which may not be very useful in log output.

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {res.EMAIL, res.USERNAME} );

OR you can use

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {email=res.EMAIL, username=res.USERNAME} );

Explanation :

1. Select employee from the db as res.

2. Filter the employee details as per the where condition.

3. Select required fields from the employee object by creating an Anonymous object using new { }

I also got the same problem from cmd and resolved using the following steps.

First install the https://msysgit.github.io/ (if not alredy installed). Then set the Git path as suggested by skinneejoe:

set PATH=%PATH%;C:\Program Files\Git\bin;

Or this (notice the (x86)):

set PATH=%PATH%;C:\Program Files (x86)\Git\bin;

In app store connect now if we are using ads in our app then we will answer as yes to Does this app use the Advertising Identifier (IDFA)?

further 3 questions will be asked as

if your using just admob then check the first one and leave other two unchecked. Other two options (2nd , 3rd ) will be checked if your using app flyer to show ads. all options are explained with detail here

This type of issue crops up for me now that I've moved to Python 3. I had no idea Python 2 was simply steam rolling any issues with file encoding.

I found this nice explanation of the differences and how to find a solution after none of the above worked for me.

http://python-notes.curiousefficiency.org/en/latest/python3/text_file_processing.html

In short, to make Python 3 behave as similarly as possible to Python 2 use:

with open(filename, encoding="latin-1") as datafile:
    # work on datafile here

However, read the article, there is no one size fits all solution.

In the Latest Android Studio 3.1.3, Dependency:

implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'

or

Even in latest by 27th of Aug 18 ie

implementation 'com.android.support:appcompat-v7:28.0.0-rc01' facing similar issue

Change it to

    implementation 'com.android.support:appcompat-v7:28.0.0-alpha1

This will solve your problem of Preview.

UPDATE

Still, in beta01 there is a preview problem for latest appcompact v7 library make the above change as changing it to alpha01 for solving rendering problem

I think I have found a better way. You don't have to put attributes into your classes. I've made two methods for serialization and deserialization which take generic list as parameter.

Take a look (it works for me):

private void SerializeParams<T>(XDocument doc, List<T> paramList)
    {
        System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(paramList.GetType());

        System.Xml.XmlWriter writer = doc.CreateWriter();

        serializer.Serialize(writer, paramList);

        writer.Close();           
    }

private List<T> DeserializeParams<T>(XDocument doc)
    {
        System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(List<T>));

        System.Xml.XmlReader reader = doc.CreateReader();

        List<T> result = (List<T>)serializer.Deserialize(reader);
        reader.Close();

        return result;
    }

So you can serialize whatever list you want! You don't need to specify the list type every time.

        List<AssemblyBO> list = new List<AssemblyBO>();
        list.Add(new AssemblyBO());
        list.Add(new AssemblyBO() { DisplayName = "Try", Identifier = "243242" });
        XDocument doc = new XDocument();
        SerializeParams<T>(doc, list);
        List<AssemblyBO> newList = DeserializeParams<AssemblyBO>(doc);

This works

@interface RGBComponents : NSObject {

    float components[8];

}

@property(readonly) float * components;

- (float *) components {
    return components;
}

First you have to create a li(with id and value as you required) then add it to your ul.

Javascript ::

addAnother = function() {
    var ul = document.getElementById("list");
    var li = document.createElement("li");
    var children = ul.children.length + 1
    li.setAttribute("id", "element"+children)
    li.appendChild(document.createTextNode("Element "+children));
    ul.appendChild(li)
}

Check this example that add li element to ul.

try this on google search (or click here)

255 * .2 to hex

it will generate 0x33 as a result.

However, google does not round off values so you can only use 1-digit multipliers. if you want to use say .85, you have to get the rounded-off value of 255 * .85 first, then type (rounded-value here) to hex in google search.

From the jinja docs section HTML Escaping:

When automatic escaping is enabled everything is escaped by default except for values explicitly marked as safe. Those can either be marked by the application or in the template by using the |safe filter.

Example:

 <div class="info">
   {{data.email_content|safe}}
 </div>

I'm using Angular 5.

In my case, I needed to import ReactiveFormsModule too.

File app.module.ts (or anymodule.module.ts):

import { FormsModule, ReactiveFormsModule } from '@angular/forms';

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    ReactiveFormsModule
  ],

If you do not have the ability to modify your php.ini file, use cURL: PHP Curl And Cookies

Here is an example function I created:

function get_web_page( $url, $cookiesIn = '' ){
        $options = array(
            CURLOPT_RETURNTRANSFER => true,     // return web page
            CURLOPT_HEADER         => true,     //return headers in addition to content
            CURLOPT_FOLLOWLOCATION => true,     // follow redirects
            CURLOPT_ENCODING       => "",       // handle all encodings
            CURLOPT_AUTOREFERER    => true,     // set referer on redirect
            CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
            CURLOPT_TIMEOUT        => 120,      // timeout on response
            CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
            CURLINFO_HEADER_OUT    => true,
            CURLOPT_SSL_VERIFYPEER => true,     // Validate SSL Cert
            CURLOPT_HTTP_VERSION   => CURL_HTTP_VERSION_1_1,
            CURLOPT_COOKIE         => $cookiesIn
        );

        $ch      = curl_init( $url );
        curl_setopt_array( $ch, $options );
        $rough_content = curl_exec( $ch );
        $err     = curl_errno( $ch );
        $errmsg  = curl_error( $ch );
        $header  = curl_getinfo( $ch );
        curl_close( $ch );

        $header_content = substr($rough_content, 0, $header['header_size']);
        $body_content = trim(str_replace($header_content, '', $rough_content));
        $pattern = "#Set-Cookie:\\s+(?<cookie>[^=]+=[^;]+)#m"; 
        preg_match_all($pattern, $header_content, $matches); 
        $cookiesOut = implode("; ", $matches['cookie']);

        $header['errno']   = $err;
        $header['errmsg']  = $errmsg;
        $header['headers']  = $header_content;
        $header['content'] = $body_content;
        $header['cookies'] = $cookiesOut;
    return $header;
}

NOTE: In revisiting this function I noticed that I had disabled SSL checks in this code. That is generally a BAD thing even though in my particular case the site I was using it on was local and was safe. As a result I've modified this code to have SSL checks on by default. If for some reason you need to change that, you can simply update the value for CURLOPT_SSL_VERIFYPEER, but I wanted the code to be secure by default if someone uses this.

Combining the previous answers provides these solutions:

if (typeof str == 'string' || str instanceof String)

or

Object.prototype.toString.call(str) == '[object String]'

I went through the Android Device Monitor

1. Click on device
2. Select Android Device Monitor's File Explorer tab
3. Select Pictures folder (path: data -> media -> 0 -> Pictures)
4. Click "Push folders on to device" icon
5. Select pic from computer and ok.

This should do the trick:

window.onload = function(event) {
    event.stopPropagation(true);
    window.location.href="http://www.google.com";
};

Good luck  ;)

You have to be careful, server responses in the range of 4xx and 5xx throw a WebException. You need to catch it, and then get status code from a WebException object:

try
{
    wResp = (HttpWebResponse)wReq.GetResponse();
    wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
    wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}

Update with Swift 3

    button.layer.borderWidth = 0.8
    button.layer.borderColor = UIColor.blue.cgColor

I've had a lot of success using thoonk.js along with thoonk.py. Thoonk leverages Redis (in-memory key-value store) to give you feed (think publish/subscribe), queue and job patterns for communication.

Why is this better than unix sockets or direct tcp sockets? Overall performance may be decreased a little, however Thoonk provides a really simple API that simplifies having to manually deal with a socket. Thoonk also helps make it really trivial to implement a distributed computing model that allows you to scale your python workers to increase performance, since you just spin up new instances of your python workers and connect them to the same redis server.

(In Kotlin) If you are going to put the answer into a TextView or something you can instead use a string resource:

<string name="time">%02d:%02d</string>

And then you can use this String resource to then set the text at run time using:

private fun setTime(time: Int) {
    val hour = time / 60
    val min = time % 60
    main_time.text = getString(R.string.time, hour, min)
}

Just do it! Don't sweat the details.

You cannot check window.history.length as it contains the amount of pages in you visited in total in a given session:

window.history.length (Integer)

Read-only. Returns the number of elements in the session history, including the currently loaded page. For example, for a page loaded in a new tab this property returns 1. ^{Cite 1}

Lets say a user visits your page, clicks on some links and goes back:

Now window.history.length is 4. You cannot traverse through the history items due to security reasons. Otherwise on could could read the user's history and get his online banking session id or other sensitive information.

You can set a timeout, that will enable you to act if the previous page isn't loaded in a given time. However, if the user has a slow Internet connection and the timeout is to short, this method will redirect him to your default location all the time:

window.goBack = function (e){
    var defaultLocation = "http://www.mysite.com";
    var oldHash = window.location.hash;

    history.back(); // Try to go back

    var newHash = window.location.hash;

    /* If the previous page hasn't been loaded in a given time (in this case
    * 1000ms) the user is redirected to the default location given above.
    * This enables you to redirect the user to another page.
    *
    * However, you should check whether there was a referrer to the current
    * site. This is a good indicator for a previous entry in the history
    * session.
    *
    * Also you should check whether the old location differs only in the hash,
    * e.g. /index.html#top --> /index.html# shouldn't redirect to the default
    * location.
    */

    if(
        newHash === oldHash &&
        (typeof(document.referrer) !== "string" || document.referrer  === "")
    ){
        window.setTimeout(function(){
            // redirect to default location
            window.location.href = defaultLocation;
        },1000); // set timeout in ms
    }
    if(e){
        if(e.preventDefault)
            e.preventDefault();
        if(e.preventPropagation)
            e.preventPropagation();
    }
    return false; // stop event propagation and browser default event
}

<span class="goback" onclick="goBack();">Go back!</span>

Note that typeof(document.referrer) !== "string" is important, as browser vendors can disable the referrer due to security reasons (session hashes, custom GET URLs). But if we detect a referrer and it's empty, it's probaly save to say that there's no previous page (see note below). Still there could be some strange browser quirk going on, so it's safer to use the timeout than to use a simple redirection.

EDIT: Don't use <a href='#'>...</a>, as this will add another entry to the session history. It's better to use a <span> or some other element. Note that typeof document.referrer is always "string" and not empty if your page is inside of a (i)frame.

If you're looking for something more straight forward to implement (and it doesn't include pie/donut charts) then I recommend WilliamChart. Specially if motion takes an important role in your app design. In other hand if you want featured charts, then go for MPAndroidChart.

Adding to @zzzzzzz answer, I ran the command:python3 -c "import sys; print(sys.path)" and it provided me with different paths comparing to the same command with python. The paths that were displayed with python3 were "python3 oriented".

See the output of the two different commands:

python -c "import sys; print(sys.path)"

['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/local/lib/python2.7/dist-packages/setuptools-39.1.0-py2.7.egg', '/usr/lib/python2.7/dist-packages']

I recommend using tqdm - https://pypi.python.org/pypi/tqdm - which makes it simple to turn any iterable or process into a progress bar, and handles all messing about with terminals needed.

From the documentation: "tqdm can easily support callbacks/hooks and manual updates. Here’s an example with urllib"

import urllib
from tqdm import tqdm

def my_hook(t):
  """
  Wraps tqdm instance. Don't forget to close() or __exit__()
  the tqdm instance once you're done with it (easiest using `with` syntax).

  Example
  -------

  >>> with tqdm(...) as t:
  ...     reporthook = my_hook(t)
  ...     urllib.urlretrieve(..., reporthook=reporthook)

  """
  last_b = [0]

  def inner(b=1, bsize=1, tsize=None):
    """
    b  : int, optional
        Number of blocks just transferred [default: 1].
    bsize  : int, optional
        Size of each block (in tqdm units) [default: 1].
    tsize  : int, optional
        Total size (in tqdm units). If [default: None] remains unchanged.
    """
    if tsize is not None:
        t.total = tsize
    t.update((b - last_b[0]) * bsize)
    last_b[0] = b
  return inner

eg_link = 'http://www.doc.ic.ac.uk/~cod11/matryoshka.zip'
with tqdm(unit='B', unit_scale=True, miniters=1,
          desc=eg_link.split('/')[-1]) as t:  # all optional kwargs
    urllib.urlretrieve(eg_link, filename='/dev/null',
                       reporthook=my_hook(t), data=None)

I needed to add this event to multiple elements that might have a scrollbar. For the cases where no scrollbar was present, the main scrollbar didn't work as it should. So i made a small change to @Šime code as follows:

$( '.scrollable' ).on( 'mousewheel DOMMouseScroll', function ( e ) {
    if($(this).prop('scrollHeight') > $(this).height())
    {
        var e0 = e.originalEvent, delta = e0.wheelDelta || -e0.detail;

        this.scrollTop += ( delta < 0 ? 1 : -1 ) * 30;
        e.preventDefault();
    }       
});

Now, only elements with a scrollbar will prevent the main scroll from begin stopped.

I've investigated this issue, referring to the LayoutInflater docs and setting up a small sample demonstration project. The following tutorials shows how to dynamically populate a layout using LayoutInflater.

Before we get started see what LayoutInflater.inflate() parameters look like:

• resource: ID for an XML layout resource to load (e.g., R.layout.main_page)
• root: Optional view to be the parent of the generated hierarchy (if attachToRoot is true), or else simply an object that provides a set of LayoutParams values for root of the returned hierarchy (if attachToRoot is false.)

• attachToRoot: Whether the inflated hierarchy should be attached to the root parameter? If false, root is only used to create the correct subclass of LayoutParams for the root view in the XML.

• Returns: The root View of the inflated hierarchy. If root was supplied and attachToRoot is true, this is root; otherwise it is the root of the inflated XML file.

Now for the sample layout and code.

Main layout (main.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</LinearLayout>

Added into this container is a separate TextView, visible as small red square if layout parameters are successfully applied from XML (red.xml):

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="25dp"
    android:layout_height="25dp"
    android:background="#ff0000"
    android:text="red" />

Now LayoutInflater is used with several variations of call parameters

public class InflaterTest extends Activity {

    private View view;

    @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      setContentView(R.layout.main);
      ViewGroup parent = (ViewGroup) findViewById(R.id.container);

      // result: layout_height=wrap_content layout_width=match_parent
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view);

      // result: layout_height=100 layout_width=100
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view, 100, 100);

      // result: layout_height=25dp layout_width=25dp
      // view=textView due to attachRoot=false
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, false);
      parent.addView(view);

      // result: layout_height=25dp layout_width=25dp 
      // parent.addView not necessary as this is already done by attachRoot=true
      // view=root due to parent supplied as hierarchy root and attachRoot=true
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, true);
    }
}

The actual results of the parameter variations are documented in the code.

SYNOPSIS: Calling LayoutInflater without specifying root leads to inflate call ignoring the layout parameters from the XML. Calling inflate with root not equal null and attachRoot=true does load the layout parameters, but returns the root object again, which prevents further layout changes to the loaded object (unless you can find it using findViewById()). The calling convention you most likely would like to use is therefore this one:

loadedView = LayoutInflater.from(context)
                .inflate(R.layout.layout_to_load, parent, false);

To help with layout issues, the Layout Inspector is highly recommended.

You can select your desired columns and do it by assignment:

df[['a', 'b']] = df[['a','b']].fillna(value=0)

The resulting output is as expected:

     a    b    c
0  1.0  4.0  NaN
1  2.0  5.0  NaN
2  3.0  0.0  7.0
3  0.0  6.0  8.0

(Tested in Chrome while playing videos on YouTube, but should work anywhere--especially useful for speeding up online training videos).

You can use "accept" attribute as a filter in the file select box. Using "accept" help you filter input files base on their "suffix" or their "meme type"

1.Filter based on suffix: Here "accept" attribute just allow to select files with .jpeg extension.

<input type="file" accept=".jpeg" />

2.Filter based on "file type" Here "accept" attribute just allow to select file with "image/jpeg" type.

<input type="file" accept="image/jpeg" />

Important: We can change or delete the extension of a file, without changing the meme type. For example it is possible to have a file without extension, but the type of this file can be "image/jpeg". So this file can not pass the accept=".jpeg" filter. but it can pass accept="image/jpeg".

3.We can use * to select all kind of a file type. For example below code allow to select all kind of images. for example "image/png" or "image/jpeg" or ... . All of them are allowed.

<input type="file" accept="image/*" /> 

4.We can use cama ( , ) as an "or operator" in select attribute. For example to allow all kind of images or pdf files we can use this code:

<input type="file" accept="image/* , application/pdf" />

Check out your php.ini, you can set these values there.

Here's the description in the php manual: http://php.net/manual/en/mail.configuration.php

If you want to use several different SMTP servers in your application, I recommend using a "bigger" mailing framework, p.e. Swiftmailer

It's not bullet-proof but for UNIX environments simple test like

if run("which python3").find("venv") == -1:
    # something when not executed from venv

works great for me. It's simpler then testing existing of some attribute and, anyway, you should name your venv directory venv.

Found a site on google explaining some changes, according to the author of the page fb does not allow custom buttons. Heres the website.

Unfortunately, it’s against Facebook’s developer policies, which state:

You must not circumvent our intended limitations on core Facebook features.

The Facebook Connect button is intended to be rendered in FBML, which means it’s only meant to look the way Facebook lets it.

I had the same warning using the raster package.

> my_mask[my_mask[] != 1] <- NA
Error: cannot allocate vector of size 5.4 Gb

The solution is really simple and consist in increasing the storage capacity of R, here the code line:

##To know the current storage capacity
> memory.limit()
[1] 8103
## To increase the storage capacity
> memory.limit(size=56000)
[1] 56000    
## I did this to increase my storage capacity to 7GB

Hopefully, this will help you to solve the problem Cheers

The top 2 answers (from Adam Robinson and Andrejs Cainikovs) are kinda, sorta correct, in that they do technically work, but their explanations are wrong and so could be misleading in many cases. For example, while the SQL_Latin1_General_CP1_CI_AS collation will work in many cases, it should not be assumed to be the appropriate case-insensitive collation. In fact, given that the O.P. is working in a database with a case-sensitive (or possibly binary) collation, we know that the O.P. isn't using the collation that is the default for so many installations (especially any installed on an OS using US English as the language): SQL_Latin1_General_CP1_CI_AS. Sure, the O.P. could be using SQL_Latin1_General_CP1_CS_AS, but when working with VARCHAR data, it is important to not change the code page as it could lead to data loss, and that is controlled by the locale / culture of the collation (i.e. Latin1_General vs French vs Hebrew etc). Please see point # 9 below.

The other four answers are wrong to varying degrees.

I will clarify all of the misunderstandings here so that readers can hopefully make the most appropriate / efficient choices.

1. Do not use UPPER(). That is completely unnecessary extra work. Use a COLLATE clause. A string comparison needs to be done in either case, but using UPPER() also has to check, character by character, to see if there is an upper-case mapping, and then change it. And you need to do this on both sides. Adding COLLATE simply directs the processing to generate the sort keys using a different set of rules than it was going to by default. Using COLLATE is definitely more efficient (or "performant", if you like that word :) than using UPPER(), as proven in this test script (on PasteBin).

   There is also the issue noted by @Ceisc on @Danny's answer:

   In some languages case conversions do not round-trip. i.e. LOWER(x) != LOWER(UPPER(x)).

   The Turkish upper-case "I" is the common example.

2. No, collation is not a database-wide setting, at least not in this context. There is a database-level default collation, and it is used as the default for altered and newly created columns that do not specify the COLLATE clause (which is likely where this common misconception comes from), but it does not impact queries directly unless you are comparing string literals and variables to other string literals and variables, or you are referencing database-level meta-data.

3. No, collation is not per query.

4. Collations are per predicate (i.e. something operand something) or expression, not per query. And this is true for the entire query, not just the WHERE clause. This covers JOINs, GROUP BY, ORDER BY, PARTITION BY, etc.

5. No, do not convert to VARBINARY (e.g.convert(varbinary, myField) = convert(varbinary, 'sOmeVal')) for the following reasons:

   1. that is a binary comparison, which is not case-insensitive (which is what this question is asking for)
   2. if you do want a binary comparison, use a binary collation. Use one that ends with _BIN2 if you are using SQL Server 2008 or newer, else you have no choice but to use one that ends with _BIN. If the data is NVARCHAR then it doesn't matter which locale you use as they are all the same in that case, hence Latin1_General_100_BIN2 always works. If the data is VARCHAR, you must use the same locale that the data is currently in (e.g. Latin1_General, French, Japanese_XJIS, etc) because the locale determines the code page that is used, and changing code pages can alter the data (i.e. data loss).
   3. using a variable-length datatype without specifying the size will rely on the default size, and there are two different defaults depending on the context where the datatype is being used. It is either 1 or 30 for string types. When used with CONVERT() it will use the 30 default value. The danger is, if the string can be over 30 bytes, it will get silently truncated and you will likely get incorrect results from this predicate.
   4. Even if you want a case-sensitive comparison, binary collations are not case-sensitive (another very common misconception).

6. No, LIKE is not always case-sensitive. It uses the collation of the column being referenced, or the collation of the database if a variable is compared to a string literal, or the collation specified via the optional COLLATE clause.

7. LCASE is not a SQL Server function. It appears to be either Oracle or MySQL. Or possibly Visual Basic?

8. Since the context of the question is comparing a column to a string literal, neither the collation of the instance (often referred to as "server") nor the collation of the database have any direct impact here. Collations are stored per each column, and each column can have a different collation, and those collations don't need to be the same as the database's default collation or the instance's collation. Sure, the instance collation is the default for what a newly created database will use as its default collation if the COLLATE clause wasn't specified when creating the database. And likewise, the database's default collation is what an altered or newly created column will use if the COLLATE clause wasn't specified.

9. You should use the case-insensitive collation that is otherwise the same as the collation of the column. Use the following query to find the column's collation (change the table's name and schema name):

   SELECT col.*
   FROM   sys.columns col
   WHERE  col.[object_id] = OBJECT_ID(N'dbo.TableName')
   AND    col.[collation_name] IS NOT NULL;
   

   Then just change the _CS to be _CI. So, Latin1_General_100_CS_AS would become Latin1_General_100_CI_AS.

   If the column is using a binary collation (ending in _BIN or _BIN2), then find a similar collation using the following query:

   SELECT *
   FROM   sys.fn_helpcollations() col
   WHERE  col.[name] LIKE N'{CurrentCollationMinus"_BIN"}[_]CI[_]%';
   

   For example, assuming the column is using Japanese_XJIS_100_BIN2, do this:

   SELECT *
   FROM   sys.fn_helpcollations() col
   WHERE  col.[name] LIKE N'Japanese_XJIS_100[_]CI[_]%';

I like SQuirreL SQL Client, and NetBeans is very useful; but more often, I just fire up the built-in org.h2.tools.Server and browse port 8082:

Yes, c[i]='' is not a valid code. We parenthesis character constant between ' ', e.g. c[i] = 'A'; char A. but you don't write any char in between ''.

Empty space is nothing but suppose if you wants to assigned space then do:

c[i] = ' ';
//      ^  space 

if wants to assigned nul char then do:

c[i] = '\0';
//       ^ null symbol 

Example: Suppose if c[] a string (nul \0 terminated char array) if you having a string. for example:

char c[10] = {'a', '2', 'c', '\0'};

And you replace second char with space:

c[1] = ' ';

and if you print it using printf as follows:

printf("\n c: %s", c);

then output would be:

  c:  a  c
//      ^ space printed 

And you replace second char with '\0':

c[1] = '\0';

then output would be:

  c:  a

because string terminated with \0.

Swift 4, I have used Enum for handling UserDefaults.

This is just a sample code. You can customize it as per your requirements.

For Storing, Retrieving, Removing. In this way just add a key for your UserDefaults key to the enum. Handle values while getting and storing according to dataType and your requirements.

enum UserDefaultsConstant : String {
    case AuthToken, FcmToken

    static let defaults = UserDefaults.standard


   //Store
    func setValue(value : Any) {
        switch self {
        case .AuthToken,.FcmToken:
            if let _ = value as? String {
                UserDefaults.standard.set(value, forKey: self.rawValue)
            }
            break
        }

        UserDefaults.standard.synchronize()
    }

   //Retrieve
    func getValue() -> Any? {
        switch self {
        case .AuthToken:
            if(UserDefaults.standard.value(forKey: UserDefaultsConstant.AuthToken.rawValue) != nil) {

                return "Bearer "+(UserDefaults.standard.value(forKey: UserDefaultsConstant.AuthToken.rawValue) as! String)
            }
            else {
                return ""
            }

        case .FcmToken:

            if(UserDefaults.standard.value(forKey: UserDefaultsConstant.FcmToken.rawValue) != nil) {
                print(UserDefaults.standard.value(forKey: UserDefaultsConstant.FcmToken.rawValue))
                return (UserDefaults.standard.value(forKey: UserDefaultsConstant.FcmToken.rawValue) as! String)
            }
            else {
                return ""
            }
        }
    }

    //Remove
    func removeValue() {
        UserDefaults.standard.removeObject(forKey: self.rawValue)
        UserDefaults.standard.synchronize()
    }
}

For storing a value in userdefaults,

if let authToken = resp.data?.token {
     UserDefaultsConstant.AuthToken.setValue(value: authToken)
    }

For retrieving a value from userdefaults,

//As AuthToken value is a string
    (UserDefaultsConstant.AuthToken.getValue() as! String)

First, have to check

SELECT * FROM university WHERE course_name LIKE '%&amp%'

Next, have to update

One can think of Grep as a restricted Sed, or of Sed as a generalized Grep. In this case, Sed is one good, lightweight tool that does what you want -- though, of course, there exist several other reasonable ways to do it, too.

Unless you tell the development server that it's running in development mode, it will assume you're using it in production and warn you not to. The development server is not intended for use in production. It is not designed to be particularly efficient, stable, or secure.

Enable development mode by setting the FLASK_ENV environment variable to development.

$ export FLASK_ENV=development
$ flask run

If you're running in PyCharm (or probably any other IDE) you can set environment variables in the run configuration.

Development mode enables the debugger and reloader by default. If you don't want these, pass --no-debugger or --no-reloader to the run command.

That warning is just a warning though, it's not an error preventing your app from running. If your app isn't working, there's something else wrong with your code.

I understand that this question is old, but there is a good solution for it in HTML5. You can wrap it all in a <figure></figure> tag. The code would look something like this:

<div id="wrapper">
<figure>

<a href="mailto:[email protected]">
<img id="fblogo" border="0" alt="Mail" src="http://olympiahaacht.be/wp- 
content/uploads/2012/07/email-icon-e1343123697991.jpg"/>
</a>

content/uploads/2012/04/FacebookButtonRevised-e1334605872360.jpg"/>
</a>

</figure>
</div>

and the CSS:

#wrapper{
 text-align:center;
}

import * as csv from 'fast-csv';
import * as fs from 'fs';
interface Row {
  [s: string]: string;
}
type RowCallBack = (data: Row, index: number) => object;
export class CSVReader {
  protected file: string;
  protected csvOptions = {
    delimiter: ',',
    headers: true,
    ignoreEmpty: true,
    trim: true
  };
  constructor(file: string, csvOptions = {}) {
    if (!fs.existsSync(file)) {
      throw new Error(`File ${file} not found.`);
    }
    this.file = file;
    this.csvOptions = Object.assign({}, this.csvOptions, csvOptions);
  }
  public read(callback: RowCallBack): Promise < Array < object >> {
    return new Promise < Array < object >> (resolve => {
      const readStream = fs.createReadStream(this.file);
      const results: Array < any > = [];
      let index = 0;
      const csvStream = csv.parse(this.csvOptions).on('data', async (data: Row) => {
        index++;
        results.push(await callback(data, index));
      }).on('error', (err: Error) => {
        console.error(err.message);
        throw err;
      }).on('end', () => {
        resolve(results);
      });
      readStream.pipe(csvStream);
    });
  }
}

import { CSVReader } from '../src/helpers/CSVReader';
(async () => {
  const reader = new CSVReader('./database/migrations/csv/users.csv');
  const users = await reader.read(async data => {
    return {
      username: data.username,
      name: data.name,
      email: data.email,
      cellPhone: data.cell_phone,
      homePhone: data.home_phone,
      roleId: data.role_id,
      description: data.description,
      state: data.state,
    };
  });
  console.log(users);
})();

For Unescape You can simply use this functions:

System.Text.RegularExpressions.Regex.Unescape(string)

System.Uri.UnescapeDataString(string)

I suggest using this method (It works better with UTF-8):

UnescapeDataString(string)

Yes, you can do it by:

-- Install Atom

-- Install Python on your system. Atom requires the latest version of Python (currently 3.8.5). Note that Anaconda sometimes may not have this version, and depending on how you installed it, it may not have been added to the PATH. Install Python via https://www.python.org/ and make sure to check the option of "Add to PATH"

-- Install "scripts" on Atom via "Install packages"

-- Install any other autocomplete package like Kite on Atom if you want that feature.

-- Run it

I tried the normal way (I had Python installed via Anaconda) but Atom did not detect it & gave me an error when I tried to run Python. This is the way around it.

simply iterate over the list then check the properties of each object.

for (var i = 0; i < jsonObj.length; ++i) {
    if (jsonObj[i]['Id'] === '3') {
        jsonObj[i]['Username'] = 'Thomas';
    }
}

input = InputBox("Text:")

If input <> "" Then
   ' Normal
Else
   ' Cancelled, or empty
End If

From MSDN:

If the user clicks Cancel, the function returns a zero-length string ("").

If you want to achieve this selectively (ie: only to that particular link), you can use a non-breaking space instead of a normal space:

<li>submit&nbsp;resume</li>

https://en.wikipedia.org/wiki/Non-breaking_space#Encodings

edit: I understand that this is HTML, not CSS as requested by the OP, but some may find it helpful…

Bring up the Package Manager Console in Visual Studio - it's in Tools / NuGet Package Manager / Package Manager Console. Then run the Install-Package command:

Install-Package Common.Logging -Version 1.2.0

See the command reference for details.

Edit: In order to list versions of a package you can use the Get-Package command with the remote argument and a filter:

Get-Package -ListAvailable -Filter Common.Logging -AllVersions

By pressing tab after the version option in the Install-Package command, you get a list of the latest available versions.

Try in2csv!

Usage:

in2csv file.xlsx > file.csv

In short: It's a shorthand notation for a mathematical hack.

Long explanation:

You can't do a cross product with vectors in 2D space. The operation is not defined there.

However, often it is interesting to evaluate the cross product of two vectors assuming that the 2D vectors are extended to 3D by setting their z-coordinate to zero. This is the same as working with 3D vectors on the xy-plane.

If you extend the vectors that way and calculate the cross product of such an extended vector pair you'll notice that only the z-component has a meaningful value: x and y will always be zero.

That's the reason why the z-component of the result is often simply returned as a scalar. This scalar can for example be used to find the winding of three points in 2D space.

From a pure mathematical point of view the cross product in 2D space does not exist, the scalar version is the hack and a 2D cross product that returns a 2D vector makes no sense at all.

Looks like jQuery takes a guess about the datatype. It does the JSON parsing even though you're not calling getJSON()-- then when you try to call JSON.parse() on an object, you're getting the error.

Further explanation can be found in Aditya Mittal's answer.

You could use setInterval for this.

<script type="text/javascript">
function myFunction () {
    console.log('Executed!');
}

var interval = setInterval(function () { myFunction(); }, 60000);
</script>

Disable the timer by setting clearInterval(interval).

Try DBComparer, it's free and fast:

http://dbcomparer.com/

You can try with this:

WITH CTE_A As (SELECT COUNT(*) as articleNumber,A.UserID  as UserID FROM Articles A
           Inner Join Users U
           on  A.userId = U.userId 
           Group By A.userId , U.userId   ),

B as (Select us.registrationDate,

      CASE
         WHEN CTE_A.articleNumber < 2 THEN 'Ama'
         WHEN CTE_A.articleNumber < 5 THEN 'SemiAma' 
         WHEN CTE_A.articleNumber < 7 THEN 'Good'  
         WHEN CTE_A.articleNumber < 9 THEN 'Better' 
         WHEN CTE_A.articleNumber < 12 THEN 'Best'
         ELSE 'Outstanding'
         END as Ranking,
         us.hobbies, etc...
         FROM USERS Us Inner Join CTE_A 
         on CTE_A.UserID=us.UserID)

Select * from B

You can use .Length == 0 if the length is empty and the array exists, but are you sure it's not null?

select * from (select name, ID from Empoyee) Visits
    pivot(sum(ID) for name
    in ([Emp1],
    [Emp2],
    [Emp3]
    ) ) as pivottable;

here is a simple javascript for that

call this when you need to scroll the screen to an element which has id="yourSpecificElementId"

window.scroll(0,findPos(document.getElementById("yourSpecificElementId")));

and you need this function for the working:

//Finds y value of given object
function findPos(obj) {
    var curtop = 0;
    if (obj.offsetParent) {
        do {
            curtop += obj.offsetTop;
        } while (obj = obj.offsetParent);
    return [curtop];
    }
}

the screen will be scrolled to your specific element.

Starting with Firefox 65 an about:config flag exists now so console API calls like console.log() land in the output stream and thus the log file (see (https://github.com/mozilla/geckodriver/issues/284#issuecomment-458305621).

profile = new FirefoxProfile();
profile.setPreference("devtools.console.stdout.content", true);

If you are using Toad for MySQL steps to import a file is as follows:

1. create a table in MySQL with the same columns that of the file to be imported.
2. now the table is created, goto > Tools > Import > Import Wizard
3. now in the import wizard dialogue box, click Next.
4. click Add File, browse and select the file to be imported.
5. choose the correct dilimination.("," seperated for .csv file)
6. click Next, check if the mapping is done properly.
7. click Next, select the "A single existing table" radio button also select the table that to be mapped from the dropdown menu of Tables.
8. Click next and finish the process.

I had faced the similar issue while using Convert.ToSingle(my_value) If the OS language settings is English 2.5 (example) will be taken as 2.5 If the OS language is German, 2.5 will be treated as 2,5 which is 25 I used the invariantculture IFormat provided and it works. It always treats '.' as '.' instead of ',' irrespective of the system language.

float var = Convert.ToSingle(my_value, System.Globalization.CultureInfo.InvariantCulture);

Try this:

The error means that your are trying to look up JNDI name, that is not attached to any EJB component - the component with that name does not exist.

As far as dir structure is concerned: you have to create a JAR file with EJB components. As I understand you want to play with EJB 2.X components (at least the linked example suggests that) so the structure of the JAR file should be:

/com/mypackage/MyEJB.class /com/mypackage/MyEJBInterface.class /com/mypackage/etc... etc... java classes /META-INF/ejb-jar.xml /META-INF/jboss.xml

The JAR file is more or less ZIP file with file extension changed from ZIP to JAR.

BTW. If you use JBoss 5, you can work with EJB 3.0, which are much more easier to configure. The simplest component is

@Stateless(mappedName="MyComponentName")
@Remote(MyEJBInterface.class)
public class MyEJB implements MyEJBInterface{
   public void bussinesMethod(){

   }
}

No ejb-jar.xml, jboss.xml is needed, just EJB JAR with MyEJB and MyEJBInterface compiled classes.

Now in your client code you need to lookup "MyComponentName".

An out parameter is a ref parameter with a special Out() attribute added. If a parameter to a C# method is declared as out, the compiler will require that the parameter be written before it can be read and before the method can return. If C# calls a method whose parameter includes an Out() attribute, the compiler will, for purposes of deciding whether to report "undefined variable" errors, pretend that the variable is written immediately before calling the method. Note that because other .net languages do not attach the same meaning to the Out() attribute, it is possible that calling a routine with an out parameter will leave the variable in question unaffected. If a variable is used as an out parameter before it is definitely assigned, the C# compiler will generate code to ensure that it gets cleared at some point before it is used, but if such a variable leaves and re-enters scope, there's no guarantee that it will be cleared again.

In my case this error was caused by the existence of the _MigrationsHistory table in the database. Deleting that table fixed the problem. Not sure how that table got into our test environment database.

To solve the problem of getting the number instead of text using Prise's extension method.

                         , Name = e.ToString() };

  return new SelectList(values, "Id", "Name", enumObj);
}

based on the above answers and other similar questions about CLI progress bar, I think I got a general common answer to all of them. Check it at https://stackoverflow.com/a/15860757/2254146

Here is a copy of the function, but modified to fit your style:

import time, sys

# update_progress() : Displays or updates a console progress bar
## Accepts a float between 0 and 1. Any int will be converted to a float.
## A value under 0 represents a 'halt'.
## A value at 1 or bigger represents 100%
def update_progress(progress):
    barLength = 20 # Modify this to change the length of the progress bar
    status = ""
    if isinstance(progress, int):
        progress = float(progress)
    if not isinstance(progress, float):
        progress = 0
        status = "error: progress var must be float\r\n"
    if progress < 0:
        progress = 0
        status = "Halt...\r\n"
    if progress >= 1:
        progress = 1
        status = "Done...\r\n"
    block = int(round(barLength*progress))
    text = "\rPercent: [{0}] {1}% {2}".format( "="*block + " "*(barLength-block), progress*100, status)
    sys.stdout.write(text)
    sys.stdout.flush()

Looks like

In Intellij Idea you use Ctrl+W

GCC comes with a compiler runtime library (libgcc) which it uses for (among other things) providing a low-level OS abstraction for multithreading related functionality in the languages it supports. The most relevant example is libstdc++'s C++11 <thread>, <mutex>, and <future>, which do not have a complete implementation when GCC is built with its internal Win32 threading model. MinGW-w64 provides a winpthreads (a pthreads implementation on top of the Win32 multithreading API) which GCC can then link in to enable all the fancy features.

I must stress this option does not forbid you to write any code you want (it has absolutely NO influence on what API you can call in your code). It only reflects what GCC's runtime libraries (libgcc/libstdc++/...) use for their functionality. The caveat quoted by @James has nothing to do with GCC's internal threading model, but rather with Microsoft's CRT implementation.

To summarize:

• posix: enable C++11/C11 multithreading features. Makes libgcc depend on libwinpthreads, so that even if you don't directly call pthreads API, you'll be distributing the winpthreads DLL. There's nothing wrong with distributing one more DLL with your application.
• win32: No C++11 multithreading features.

Neither have influence on any user code calling Win32 APIs or pthreads APIs. You can always use both.

I'm troubled by some of these responses. I think doubles and floats have a place in financial calculations. Certainly, when adding and subtracting non-fractional monetary amounts there will be no loss of precision when using integer classes or BigDecimal classes. But when performing more complex operations, you often end up with results that go out several or many decimal places, no matter how you store the numbers. The issue is how you present the result.

If your result is on the borderline between being rounded up and rounded down, and that last penny really matters, you should be probably be telling the viewer that the answer is nearly in the middle - by displaying more decimal places.

The problem with doubles, and more so with floats, is when they are used to combine large numbers and small numbers. In java,

System.out.println(1000000.0f + 1.2f - 1000000.0f);

results in

1.1875

The topic is quite old, yet I struggled with the same issue today while compiling cegui 0.7.1 (openVibe prerequisite).

What worked for me was to set: LDFLAGS="-Wl,--no-as-needed" in the Makefile.

I've also tried -ldl for LDFLAGS but to no avail.

showInventory(player); is passing a type as parameter. That's illegal, you need to pass an object.

For example, something like:

player p;
showInventory(p);  

I'm guessing you have something like this:

int main()
{
   player player;
   toDo();
}

which is awful. First, don't name the object the same as your type. Second, in order for the object to be visible inside the function, you'll need to pass it as parameter:

int main()
{
   player p;
   toDo(p);
}

and

std::string toDo(player& p) 
{
    //....
    showInventory(p);
    //....
}

Sometimes, when I know that I am working with numbers, I use this logic (if result is not greater than zero):

if (!$result['column']>0){

}

Okay turned out that I made a really silly mistake. The device I am using for testing is running Android 4.0.4, API level 15.

The styles.xml file that I was editing is in the default values folder. I edited the styles.xml in values-v14 folder and it works all fine now.

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

You maybe wanted to do the following:

foreach($user->data as $mydata)

    {
         echo $mydata->name . "\n";
         foreach($mydata->values as $values)
         {
              echo $values->value . "\n";
         }
    }        

i think you use this method to compress the bitmap

BitmapFactory.Option imageOpts = new BitmapFactory.Options ();
imageOpts.inSampleSize = 2;   // for 1/2 the image to be loaded
Bitmap thumb = Bitmap.createScaledBitmap (BitmapFactory.decodeFile(photoPath, imageOpts), 96, 96, false);

I actually think that's not the good way to parse it. It's not clean or it's a bit out of subject ...

• Explode is heavy
• Session is heavy
• PHP_SELF doesn't handle URLRewriting

I'd do something like ...

if ($pos_get = strpos($app_uri, '?')) $app_uri = substr($app_uri, 0, $pos_get);

• This detects whether there's an actual '?' (GET standard format)
• If it's ok, that cuts our variable before the '?' which's reserved for getting datas

Considering $app_uri as the URI/URL of my website.

By adding a callback argument, you are telling jQuery that you want to make a request for JSONP using a script element instead of a request for JSON using XMLHttpRequest.

JSONP is not JSON. It is a JavaScript program.

Change your server so it outputs the right MIME type for JSONP which is application/javascript.

(While you are at it, stop telling jQuery that you are expecting JSON as that is contradictory: dataType: 'jsonp').

You could also just overload the default console.log function:

var fs = require('fs');
var util = require('util');
var log_file = fs.createWriteStream(__dirname + '/debug.log', {flags : 'w'});
var log_stdout = process.stdout;

console.log = function(d) { //
  log_file.write(util.format(d) + '\n');
  log_stdout.write(util.format(d) + '\n');
};

Above example will log to debug.log and stdout.

Edit: See multiparameter version by Clément also on this page.

Here is my solution after many tests with if exist, pushd, dir /AD, etc...

@echo off
cd /d C:\
for /f "delims=" %%I in ('dir /a /ogn /b') do (
    call :isdir "%%I"
    if errorlevel 1 (echo F: %%~fI) else echo D: %%~fI
)
cmd/k

:isdir
echo.%~a1 | findstr /b "d" >nul
exit /b %errorlevel%

:: Errorlevel
:: 0 = folder
:: 1 = file or item not found

• It works with files that have no extension
• It works with folders named folder.ext
• It works with UNC path
• It works with double-quoted full path or with just the dirname or filename only.
• It works even if you don't have read permissions
• It works with Directory Links (Junctions).
• It works with files whose path contains a Directory Link.

2018 Solution, still other answers are valid but you dont need to use any dependency:

First you have to create a new migration:

php artisan make:migration change_appointment_time_column_type

Then in that migration file up(), try:

    Schema::table('appointments', function ($table) {
        $table->string('time')->change();
    });

If you donot change the size default will be varchar(191) but If you want to change size of the field:

    Schema::table('appointments', function ($table) {
        $table->string('time', 40)->change();
    });

Then migrate the file by:

php artisan migrate

more info from doc.

b = a(find(a~=0))

You may also use the stringr package

library(dplyr)
library(stringr)
My.Data %>% filter(str_detect(x, '^G45'))

You may not use '^' (starts with) in this case, to obtain the results you need

a = [0,1,2,3]

a.drop(1)
# => [1, 2, 3] 

a
# => [0,1,2,3]

and additionally:

[0,1,2,3].drop(2)
=> [2, 3]

[0,1,2,3].drop(3)
=> [3] 

In my case, for some reason, vendor folder was disabled on VS Code settings:

    "intelephense.files.exclude": [
        "**/.git/**",
        "**/.svn/**",
        "**/.hg/**",
        "**/CVS/**",
        "**/.DS_Store/**",
        "**/node_modules/**",
        "**/bower_components/**",
        "**/vendor/**", <-- remove this line!
        "**/resources/views/**"
    ],

By removing the line containing vendor folder it works ok on version Intelephense 1.5.4

Try something like below

 <a href="#" onclick="this.forms['formName'].submit()">Submit</a> 

arr = []
elem = int(raw_input("insert how many elements you want:"))
for i in range(0, elem):
    arr.append(int(raw_input("Enter next no :")))
print arr

I understand that the Q does not want to use a library, but I will offer this for others coming from Google searches. @EricRowell mentioned a good plugin, but, there is also another plugin you can try, html2canvas.

In our case we are using layered transparent PNG's with z-index as a "product builder" widget. Html2canvas worked brilliantly to boil the stack down without pushing images, nor using complexities, workarounds, and the "non-responsive" canvas itself. We were not able to do this smoothly/sane with the vanilla canvas+JS.

First use z-index on absolute divs to generate layered content within a relative positioned wrapper. Then pipe the wrapper through html2canvas to get a rendered canvas, which you may leave as-is, or output as an image so that a client may save it.

If you need a button like this:

You can use RaisedButton and use the child property to do this. You need to add a Row and inside row you can add a Text widget and an Icon Widget to achieve this. If you want to use png image, you can use similar widget to achieve this.

RaisedButton(
    onPressed: () {},
    color: Theme.of(context).accentColor,
    child: Padding(
      padding: EdgeInsets.fromLTRB(
          SizeConfig.safeBlockHorizontal * 5,
          0,
          SizeConfig.safeBlockHorizontal * 5,
          0),
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          Text(
            'Continue',
            style: TextStyle(
              fontSize: 20,
              fontWeight: FontWeight.w700,
              color: Colors.white,
            ),
          ),
          Icon(
            Icons.arrow_forward,
            color: Colors.white,
          )
        ],
      ),
    ),
  ),

We can add swap space in any server

create a file using dd command

 #dd if=/dev/zero of=/swapfile bs=1M count=2048
                    or
 #dd if=/dev/zero of=/swapfile bs=1024M count=2

bs is blocksize and count refers to the size in MB or GB

we can use vice versa

After creation change the permission of file :

 #chmod 600 /swapfile 

Then makeswap the file :

 #mkswap /swapfile 

Then enable the swap file with swapon command :

 #swapon  /swapfile 

Check with free command whether swap is enabled or not :

 #free -h
 #swapon -s

The best practice is definitely to avoid loops or recursions in Matlab.

Between sum(A(:)) and sum(sum(A)). In my experience, arrays in Matlab seems to be stored in a continuous block in memory as stacked column vectors. So the shape of A does not quite matter in sum(). (One can test reshape() and check if reshaping is fast in Matlab. If it is, then we have a reason to believe that the shape of an array is not directly related to the way the data is stored and manipulated.)

As such, there is no reason sum(sum(A)) should be faster. It would be slower if Matlab actually creates a row vector recording the sum of each column of A first and then sum over the columns. But I think sum(sum(A)) is very wide-spread amongst users. It is likely that they hard-code sum(sum(A)) to be a single loop, the same to sum(A(:)).

Below I offer some testing results. In each test, A=rand(size) and size is specified in the displayed texts.

First is using tic toc.

Size 100x100

They seem equivalent. Either one is good. But sum(sum(A)) requires that you know the dimension of your array is 2.

This is not a PowerShell-specific answer, but you could authenticate against the share using "NET USE" first:

net use \\server\share /user:<domain\username> <password>

And then do whatever you need to do in PowerShell...

Cells(1,1).Value2 = "'123,456"

note the single apostrophe before the number - this will signal to excel that whatever follows has to be interpreted as text.

You can put simply a flag variable, in this case is_successed.

def preorder_view(request, pk, template_name='preorders/preorder_form.html'):
    is_successed=0
    formset = PreorderHasProductsForm(request.POST)
    client= get_object_or_404(Client, pk=pk)
    if request.method=='POST':
        #populate the form with data from the request
       # formset = PreorderHasProductsForm(request.POST)
        if formset.is_valid():
            is_successed=1
            preorder_date=formset.cleaned_data['preorder_date']
            product=formset.cleaned_data['preorder_has_products']
            return render(request, template_name, {'preorder_date':preorder_date,'product':product,'is_successed':is_successed,'formset':formset})



    return render(request, template_name, {'object':client,'formset':formset})

afterwards in your template you can just put the code below

{%if is_successed == 1 %}
<h1>{{preorder_date}}</h1>
<h2> {{product}}</h2>
{%endif %}

https://github.com/yongjhih/CardView

A CardView v7 eclipse project. (from sdk/extras/android/m2repository/com/android/support/cardview-v7)

The project was built by steps:

cp {sdk}/extras/android/m2repository/com/android/support/cardview-v7/21.0.0-rc1/cardview-v7-21.0.0-rc1.aar cardview-v7-21.0.0-rc1.zip

mkdir libs/
mv classes.jar libs/cardview-v7-21.0.0-rc1.jar

You can also use the filter function from the dplyr package which returns rows with matching conditions.

> library(dplyr)

> nrow(filter(aaa, sex == 1 & group1 == 2))
[1] 3
> nrow(filter(aaa, sex == 1 & group2 == "A"))
[1] 2

TL;DR

It packs arguments passed to the function into list and dict respectively inside the function body. When you define a function signature like this:

def func(*args, **kwds):
    # do stuff

it can be called with any number of arguments and keyword arguments. The non-keyword arguments get packed into a list called args inside the function body and the keyword arguments get packed into a dict called kwds inside the function body.

func("this", "is a list of", "non-keyowrd", "arguments", keyword="ligma", options=[1,2,3])

now inside the function body, when the function is called, there are two local variables, args which is a list having value ["this", "is a list of", "non-keyword", "arguments"] and kwds which is a dict having value {"keyword" : "ligma", "options" : [1,2,3]}

This also works in reverse, i.e. from the caller side. for example if you have a function defined as:

def f(a, b, c, d=1, e=10):
    # do stuff

you can call it with by unpacking iterables or mappings you have in the calling scope:

iterable = [1, 20, 500]
mapping = {"d" : 100, "e": 3}
f(*iterable, **mapping)
# That call is equivalent to
f(1, 20, 500, d=100, e=3)

Invoke the windows port of md5sum.exe. It's about two times as fast as the .NET implementation (at least on my machine using a 1.2 GB file)

public static string Md5SumByProcess(string file) {
    var p = new Process ();
    p.StartInfo.FileName = "md5sum.exe";
    p.StartInfo.Arguments = file;            
    p.StartInfo.UseShellExecute = false;
    p.StartInfo.RedirectStandardOutput = true;
    p.Start();
    p.WaitForExit();           
    string output = p.StandardOutput.ReadToEnd();
    return output.Split(' ')[0].Substring(1).ToUpper ();
}

My self-made solution which is easy to edit:

HTML:

<div id="anti-shadow-div">
    <div id="shadow-div"></div>

    margin-left:0px; /* Set to 20px if you want shadow at the left side */
    margin-top:0px; /* Set to 20px if you want shadow at the top side */
    margin-bottom:0px; /* Set to 20px if you want shadow at the bottom side */

I have same problem and i found solution which is given below with full datepicker using simple HTML,Javascript and CSS. In this code i prepare formate like dd/mm/yyyy but you can work any.

HTML Code:

    <body>
<input type="date" id="dt" onchange="mydate1();" hidden/>
<input type="text" id="ndt"  onclick="mydate();" hidden />
<input type="button" Value="Date" onclick="mydate();" />
</body>

CSS Code:

#dt{text-indent: -500px;height:25px; width:200px;}

Javascript Code :

function mydate()
{
  //alert("");
document.getElementById("dt").hidden=false;
document.getElementById("ndt").hidden=true;
}
function mydate1()
{
 d=new Date(document.getElementById("dt").value);
dt=d.getDate();
mn=d.getMonth();
mn++;
yy=d.getFullYear();
document.getElementById("ndt").value=dt+"/"+mn+"/"+yy
document.getElementById("ndt").hidden=false;
document.getElementById("dt").hidden=true;
}

Output:

Roll-your-own generic converter for complex objects as selected item

The Balusc gives a very useful overview answer on this subject. But there is one alternative he does not present: The Roll-your-own generic converter that handles complex objects as the selected item. This is very complex to do if you want to handle all cases, but pretty simple for simple cases.

The code below contains an example of such a converter. It works in the same spirit as the OmniFaces SelectItemsConverter as it looks through the children of a component for UISelectItem(s) containing objects. The difference is that it only handles bindings to either simple collections of entity objects, or to strings. It does not handle item groups, collections of SelectItems, arrays and probably a lot of other things.

The entities that the component binds to must implement the IdObject interface. (This could be solved in other way, such as using toString.)

Note that the entities must implement equals in such a way that two entities with the same ID compares equal.

The only thing that you need to do to use it is to specify it as converter on the select component, bind to an entity property and a list of possible entities:

<h:selectOneMenu value="#{bean.user}" converter="selectListConverter">
  <f:selectItem itemValue="unselected" itemLabel="Select user..."/>
  <f:selectItem itemValue="empty" itemLabel="No user"/>
  <f:selectItems value="#{bean.users}" var="user" itemValue="#{user}" itemLabel="#{user.name}" />
</h:selectOneMenu>

Converter:

/**
 * A converter for select components (those that have select items as children).
 * 
 * It convertes the selected value string into one of its element entities, thus allowing
 * binding to complex objects.
 * 
 * It only handles simple uses of select components, in which the value is a simple list of
 * entities. No ItemGroups, arrays or other kinds of values.
 * 
 * Items it binds to can be strings or implementations of the {@link IdObject} interface.
 */
@FacesConverter("selectListConverter")
public class SelectListConverter implements Converter {

  public static interface IdObject {
    public String getDisplayId();
  }

  @Override
  public Object getAsObject(FacesContext context, UIComponent component, String value) {
    if (value == null || value.isEmpty()) {
      return null;
    }

    return component.getChildren().stream()
      .flatMap(child -> getEntriesOfItem(child))
      .filter(o -> value.equals(o instanceof IdObject ? ((IdObject) o).getDisplayId() : o))
      .findAny().orElse(null);
  }

  /**
   * Gets the values stored in a {@link UISelectItem} or a {@link UISelectItems}.
   * For other components returns an empty stream.
   */
  private Stream<?> getEntriesOfItem(UIComponent child) {
    if (child instanceof UISelectItem) {
      UISelectItem item = (UISelectItem) child;
      if (!item.isNoSelectionOption()) {
        return Stream.of(item.getValue());
      }

    } else if (child instanceof UISelectItems) {
      Object value = ((UISelectItems) child).getValue();

      if (value instanceof Collection) {
        return ((Collection<?>) value).stream();
      } else {
        throw new IllegalStateException("Unsupported value of UISelectItems: " + value);
      }
    }

    return Stream.empty();
  }

  @Override
  public String getAsString(FacesContext context, UIComponent component, Object value) {
    if (value == null) return null;
    if (value instanceof String) return (String) value;
    if (value instanceof IdObject) return ((IdObject) value).getDisplayId();

    throw new IllegalArgumentException("Unexpected value type");
  }

}

if there are multiple java processes and you wish to kill them with one command try the below command

kill -9 $(ps -ef | pgrep -f "java")

replace "java" with any process string identifier , to kill anything else.

Worked for me -

$scope.downloadFile = function () {
        Resource.downloadFile().then(function (response) {
            var blob = new Blob([response.data], { type: "application/pdf" });
            var objectUrl = URL.createObjectURL(blob);
            window.open(objectUrl);
        },
        function (error) {
            debugger;
        });
    };

Which calls the following from my resource factory-

  downloadFile: function () {
           var downloadRequst = {
                method: 'GET',
                url: 'http://localhost/api/downloadFile?fileId=dfckn4niudsifdh.pdf',
                headers: {
                    'Content-Type': "application/pdf",
                    'Accept': "application/pdf"
                },
                responseType: 'arraybuffer'
            }

            return $http(downloadRequst);
        }

Make sure your API sets the header content type too -

        response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/pdf");
        response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");

Download "json simple 1.1 jar" from this https://code.google.com/p/json-simple/downloads/detail?name=json_simple-1.1.jar&can=2&q=

And add the jar file to your lib folder

using JSONValue you can convert LinkedHashMap to json string

using Newtonsoft.Json.Linq;
using System.Linq;
using System.IO;
using System.Collections.Generic;

public List<string> GetJsonValues(string filePath, string propertyName)
{
  List<string> values = new List<string>();
  string read = string.Empty;
  using (StreamReader r = new StreamReader(filePath))
  {
    var json = r.ReadToEnd();
    var jObj = JObject.Parse(json);
    foreach (var j in jObj.Properties())
    {
      if (j.Name.Equals(propertyName))
      {
        var value = jObj[j.Name] as JArray;
        return values = value.ToObject<List<string>>();
      }
    }
    return values;
  }
}

For Apache 2.4.2 the solution is: in httpd.conf on line 265 change Require none to Require all granted. That's all.

Normally you'd just stick the code in Page_Load in your .aspx page's code-behind.

if (someVar) {
    Item1.Visible = true;
    Item2.Visible = false;
} else {
    Item1.Visible = false;
    Item2.Visible = true;
}

This assumes you've got Item1 and Item2 laid out on the page already.

There's not a good way to convert it to foreach, because mysql_fetch_array() just fetches the next result from $result_select. If you really wanted to foreach, you could do pull all the results into an array first, doing something like the following:

$result_list = array();
while($row = mysql_fetch_array($result_select)) {
   result_list[] = $row;
}

foreach($result_list as $row) {
   ...
}

But there's no good reason I can see to do that - and you still have to use the while loop, which is unavoidable due to how mysql_fetch_array() works. Why is it so important to use a foreach()?

EDIT: If this is just for learning purposes: you can't convert this to a foreach. You have to have a pre-existing array to use a foreach() instead of a while(), and mysql_fetch_array() fetches one result per call - there's no pre-existing array for foreach() to iterate through.

In my case the problem was that there was a different repository directory configuration in IntelliJ and in settings.xml file.

Check both repository directories are the same:

IntelliJ (File > Settings > Build,Execution,Deployment > Build Tools > Maven )

settings.xml (usually in C:\Users\myuser\.m2 or /home/myuser/.m2)

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">

  ...
  <localRepository>C:\Users\myuser\.m2\repository</localRepository>
  ...
</settings>

After fixing directories run:

1. Generate Folders and Update Sources for All Projects

2. Reimport all maven projects

I found an easy way to get a std::string from a String^ is to use sprintf().

char cStr[50] = { 0 };
String^ clrString = "Hello";
if (clrString->Length < sizeof(cStr))
  sprintf(cStr, "%s", clrString);
std::string stlString(cStr);

No need to call the Marshal functions!

UPDATE Thanks to Eric, I've modified the sample code to check for the size of the input string to prevent buffer overflow.

All of the replies with readonly are only suitable when this is a pure TS environment - if it's ever being made into a library then this doesn't actually prevent anything, it just provides warnings for the TS compiler itself.

Static is also not correct - that's adding a method to the Class, not to an instance of the class - so you need to address it directly.

There are several ways to manage this, but the pure TS way is to use a getter - exactly as you have done already.

The alternative way is to put it in as readonly, but then use Object.defineProperty to lock it - this is almost the same thing that is being done via the getter, but you can lock it to have a value, rather than a method to use to get it -

class MyClass {
    MY_CONSTANT = 10;

    constructor() {
        Object.defineProperty(this, "MY_CONSTANT", {value: this.MY_CONSTANT});
    }
}

The defaults make it read-only, but check out the docs for more details.

++i is slightly more efficient due to its semantics:

++i;  // Fetch i, increment it, and return it
i++;  // Fetch i, copy it, increment i, return copy

For int-like indices, the efficiency gain is minimal (if any). For iterators and other heavier-weight objects, avoiding that copy can be a real win (particularly if the loop body doesn't contain much work).

As an example, consider the following loop using a theoretical BigInteger class providing arbitrary precision integers (and thus some sort of vector-like internals):

std::vector<BigInteger> vec;
for (BigInteger i = 0; i < 99999999L; i++) {
  vec.push_back(i);
}

That i++ operation includes copy construction (i.e. operator new, digit-by-digit copy) and destruction (operator delete) for a loop that won't do anything more than essentially make one more copy of the index object. Essentially you've doubled the work to be done (and increased memory fragmentation most likely) by simply using the postfix increment where prefix would have been sufficient.

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

String#strip - remove all whitespace from the start and the end.

String#lstrip - just from the start.

String#rstrip - just from the end.

String#chomp (with no arguments) - deletes line separators (\n or \r\n) from the end.

String#chop - deletes the last character.

String#delete - x.delete(" \t\r\n") - deletes all listed whitespace.

String#gsub - x.gsub(/[[:space:]]/, '') - removes all whitespace, including unicode ones.

Note: All the methods above return a new string instead of mutating the original. If you want to change the string in place, call the corresponding method with ! at the end.

This will work from JS without coupling to HTML:

document.getElementById("click-button").onclick = onClickFunction;

function onClickFunction()
{
    return functionWithArguments('You clicked the button!');
}

function functionWithArguments(text) {
    document.getElementById("some-div").innerText = text;
}

While I haven't found a good way to specify proxy network credentials in the web.config, you might find that you can still use a non-coding solution, by including this in your web.config:

  <system.net>
    <defaultProxy useDefaultCredentials="true">
      <proxy proxyaddress="proxyAddress" usesystemdefault="True"/>
    </defaultProxy>
  </system.net>

The key ingredient in getting this going, is to change the IIS settings, ensuring the account that runs the process has access to the proxy server. If your process is running under LocalService, or NetworkService, then this probably won't work. Chances are, you'll want a domain account.

There is a small difference between both.

Second declaration assignates the reference associated to the constant SOMEto the variable str

First declaration creates a new String having for value the value of the constant SOME and assignates its reference to the variable str.

In the first case, a second String has been created having the same value that SOME which implies more inititialization time. As a consequence, you should avoid it. Furthermore, at compile time, all constants SOMEare transformed into the same instance, which uses far less memory.

As a consequence, always prefer second syntax.

You need the correct argument for the nth-child pseudo class.

• The argument should be in the form of an + b to match every a^th child starting from b.

• Both a and b are optional integers and both can be zero or negative.

  • If a is zero then there is no "every a^th child" clause.
  • If a is negative then matching is done backwards starting from b.
  • If b is zero or negative then it is possible to write equivalent expression using positive b e.g. 4n+0 is same as 4n+4. Likewise 4n-1 is same as 4n+3.

Notice that summary(fit) generates an object with all the information you need. The beta, se, t and p vectors are stored in it. Get the p-values by selecting the 4th column of the coefficients matrix (stored in the summary object):

summary(fit)$coefficients[,4] 
summary(fit)$r.squared

Try str(summary(fit)) to see all the info that this object contains.

Edit: I had misread Chase's answer which basically tells you how to get to what I give here.

I wrote a regex to help find and replace "&" within an INSERT, I hope that this helps someone.

The trick was to make sure that the "&" was with other text.

Find “(\'[^\']*(?=\&))(\&)([^\']*\')”

Replace “$1' || chr(38) || '$3”

Use the jQuery hashchange event plugin instead. Regarding your full ajax navigation, try to have SEO friendly ajax. Otherwise your pages shown nothing in browsers with JavaScript limitations.

Perfect solution I have tried it and succeed to get my index page when I have append this code in my site configuration file.

location / {
            try_files $uri $uri/ /index.php;
}

In configuration file itself explained that at "First attempt to serve request as file, then as directory, then fall back to index.html in my case it is index.php as I am providing page through php code.

The "JavaScript" way:

var lang = navigator.language || navigator.userLanguage; //no ?s necessary

Really you should be doing language detection on the server, but if it's absolutely necessary to know/use via JavaScript, it can be gotten.

There is no need to use the classpath: protocol in your schemaLocation URL if the namespace is configured correctly and the XSD file is on your classpath.

Spring doc "Registering the handler and the schema" shows how it should be done.

In your case, the problem was probably that the spring-context jar on your classpath was not 2.1. That was why changing the protocol to classpath: and putting the specific 2.1 XSD in your classpath fixed the problem.

From what I've seen, there are 2 schemas defined for the main XSD contained in a spring-* jar. Once to resolve the schema URL with the version and once without it.

As an example see this part of the spring.schemas contents in spring-context-3.0.5.RELEASE.jar:

http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
http\://www.springframework.org/schema/context/spring-context-3.0.xsd=org/springframework/context/config/spring-context-3.0.xsd
http\://www.springframework.org/schema/context/spring-context.xsd=org/springframework/context/config/spring-context-3.0.xsd

This means that (in xsi:schemaLocation)

http://www.springframework.org/schema/context/spring-context-2.5.xsd 

will be validated against

org/springframework/context/config/spring-context-2.5.xsd 

in the classpath.

http://www.springframework.org/schema/context/spring-context-3.0.xsd 

or

http://www.springframework.org/schema/context/spring-context.xsd

will be validated against

org/springframework/context/config/spring-context-3.0.xsd 

in the classpath.

http://www.springframework.org/schema/context/spring-context-2.1.xsd

is not defined so Spring will look for it using the literal URL defined in schemaLocation.

For Safari versions <5.1 the css3 property background-size doesn't work. In such cases you need webkit.

So you need to use -webkit-background-size attribute to specify the background-size.

Hence use -webkit-background-size:cover.

Reference-Safari versions using webkit

Well, first of all, you're wasting memory with the new HashMap creation call. Your second line completely disregards the reference to this created hashmap, making it then available to the garbage collector. So, don't do that, use:

private Map<String, String> someMap = (HashMap<String, String>)getApplicationContext().getBean("someMap");

Secondly, the compiler is complaining that you cast the object to a HashMap without checking if it is a HashMap. But, even if you were to do:

if(getApplicationContext().getBean("someMap") instanceof HashMap) {
    private Map<String, String> someMap = (HashMap<String, String>)getApplicationContext().getBean("someMap");
}

You would probably still get this warning. The problem is, getBean returns Object, so it is unknown what the type is. Converting it to HashMap directly would not cause the problem with the second case (and perhaps there would not be a warning in the first case, I'm not sure how pedantic the Java compiler is with warnings for Java 5). However, you are converting it to a HashMap<String, String>.

HashMaps are really maps that take an object as a key and have an object as a value, HashMap<Object, Object> if you will. Thus, there is no guarantee that when you get your bean that it can be represented as a HashMap<String, String> because you could have HashMap<Date, Calendar> because the non-generic representation that is returned can have any objects.

If the code compiles, and you can execute String value = map.get("thisString"); without any errors, don't worry about this warning. But if the map isn't completely of string keys to string values, you will get a ClassCastException at runtime, because the generics cannot block this from happening in this case.

Is this what you mean?

SELECT DISTINCT C.valueC
FROM 
C
INNER JOIN B ON C.id = B.lookupC
INNER JOIN A ON B.id = A.lookupB

If you are running MongoDB 3.2 or later version, you can limit the wiredTiger cache as mentioned above.

In /etc/mongod.conf add the wiredTiger part

...
# Where and how to store data.
storage:
  dbPath: /var/lib/mongodb
  journal:
    enabled: true
  wiredTiger:
    engineConfig:
        cacheSizeGB: 1
...

This will limit the cache size to 1GB, more info in Doc

This solved the issue for me, running ubuntu 16.04 and mongoDB 3.2

PS: After changing the config, restart the mongo daemon.

$ sudo service mongod restart

# check the status
$ sudo service mongod status

This works fro me:) may this help you as well

edit_account_name.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                if (event.getRawX() >= (edit_account_name.getRight())) {
                    //clicked
                   return true;
                }
            }
            return false;
        }
    });

Use SERVER\\ INSTANCE NAME .Using double backslash in my project solved my problem.

var result = projects.Where(p => filtedTags.All(t => p.Tags.Contains(t)));

I sometimes like using the array_reduce() function to carry out the search. It's similar to array_filter() but does not affect the searched array, allowing you to carry out multiple searches on the same array of objects.

$haystack = array($obj1, $obj2, ...); //some array of objects
$needle = 'looking for me?'; //the value of the object's property we want to find

//carry out the search
$search_results_array = array_reduce(
  $haystack,

  function($result_array, $current_item) use ($needle){
      //Found the an object that meets criteria? Add it to the the result array 
      if ($current_item->someProperty == $needle){
          $result_array[] = $current_item;
      }
      return $result_array;
  },
  array() //initially the array is empty (i.e.: item not found)
);

//report whether objects found
if (count($search_results_array) > 0){
  echo "found object(s): ";
  print_r($search_results_array[0]); //sample object found
} else {
  echo "did not find object(s): ";
}
