While there may be overlaps between the two (some web servers may even be used as application servers) the biggest difference IMHO is in the processing model and the session management:

In Web server processing model, the focus is on handling requests; the notion of "session" is pretty much virtual. That is to say that "session" is simulated by transferring the representation of state between client and server (hence REST) and/or serializing it to an external persistent storage (SQL Server, Memcached etc).

In Application server the session is usually more explicit and often takes form of an object living in memory of the application server for the entire duration of the "session".

Your question is similar to below:

What is the difference between application server and web server?

In Java: Web Container or Servlet Container or Servlet Engine : is used to manage the components like Servlets, JSP. It is a part of the web server.

Web Server or HTTP Server: A server which is capable of handling HTTP requests, sent by a client and respond back with a HTTP response.

Application Server or App Server: can handle all application operations between users and an organization's back end business applications or databases.It is frequently viewed as part of a three-tier application with: Presentation tier, logic tier,Data tier

Tomcat is an application container that is also a web server. An application container can run web-applications (have "application" scope). It is not considered Some people do not consider it a full application server as it is lacking in some aspects such as user management and the like, but getting better all the time..

You can use tail command as follows:

tail -100 <log file>   > newLogfile

Now last 100 lines will be present in newLogfile

EDIT:

More recent versions of tail as mentioned by twalberg use command:

tail -n 100 <log file>   > newLogfile

One potential solution

Thanks to Alan Haggai Alavi's solution I came up with the following potential workflow:

Step 1:

git fetch origin

Step 2:

git checkout -b localTempOfOriginMaster origin/master
git difftool HEAD~3 HEAD~2
git difftool HEAD~2 HEAD~1
git difftool HEAD~1 HEAD~0

Step 3:

git checkout master
git branch -D localTempOfOriginMaster
git merge origin/master

This is actually a pretty challenging problem that you are asking. Computing sentence similarity requires building a grammatical model of the sentence, understanding equivalent structures (e.g. "he walked to the store yesterday" and "yesterday, he walked to the store"), finding similarity not just in the pronouns and verbs but also in the proper nouns, finding statistical co-occurences / relationships in lots of real textual examples, etc.

The simplest thing you could try -- though I don't know how well this would perform and it would certainly not give you the optimal results -- would be to first remove all "stop" words (words like "the", "an", etc. that don't add much meaning to the sentence) and then run word2vec on the words in both sentences, sum up the vectors in the one sentence, sum up the vectors in the other sentence, and then find the difference between the sums. By summing them up instead of doing a word-wise difference, you'll at least not be subject to word order. That being said, this will fail in lots of ways and isn't a good solution by any means (though good solutions to this problem almost always involve some amount of NLP, machine learning, and other cleverness).

So, short answer is, no, there's no easy way to do this (at least not to do it well).

Why are you all going the hard way?

with open("myfile") as myfile:
    nonempty = filter(str.rstrip, myfile)

Convert nonempty into a list if you have the urge to do so, although I highly suggest keeping nonempty a generator as it is in Python 3.x

In Python 2.x you may use itertools.ifilter to do your bidding instead.

If you are locked out and WiFi is turned off in your Androud device then one solution is to connect your phone to a PC (connected to internet) and try to login with your google account. - it worked for me.

I'm not quite sure what you mean by "sorting the items after index 0", but if you just want to sort the array of strings returned by SerialPort.GetPortNames(), you can use Array.Sort.

Maybe this way:

const m = new Map([["a", 1], ["b", 2], ["c", 3]]);
m.map((k, v) => [k, v * 2]); // Map { 'a' => 2, 'b' => 4, 'c' => 6 }

You would only need to monkey patch Map before:

Map.prototype.map = function(func){
    return new Map(Array.from(this, ([k, v]) => func(k, v)));
}

We could have wrote a simpler form of this patch:

Map.prototype.map = function(func){
    return new Map(Array.from(this, func));
}

But we would have forced us to then write m.map(([k, v]) => [k, v * 2]); which seems a bit more painful and ugly to me.

Mapping values only

We could also map values only, but I wouldn't advice going for that solution as it is too specific. Nevertheless it can be done and we would have the following API:

const m = new Map([["a", 1], ["b", 2], ["c", 3]]);
m.map(v => v * 2); // Map { 'a' => 2, 'b' => 4, 'c' => 6 }

Just like before patching this way:

Map.prototype.map = function(func){
    return new Map(Array.from(this, ([k, v]) => [k, func(v)]));
}

Maybe you can have both, naming the second mapValues to make it clear that you are not actually mapping the object as it would probably be expected.

Have a look at the following example of the jQueryUI Autocomplete, as it is keeping a select around and I think that is what you are looking for. Hope this helps.

I had the same problem, I wanted no access of Save Dialogue.

Below code can help:

    FirefoxProfile fp = new FirefoxProfile();
    fp.setPreference("browser.download.folderList",2);
    fp.setPreference("browser.download.manager.showWhenStarting",false);
    fp.setPreference("browser.helperApps.alwaysAsk.force", false);
    // Below you have to set the content-type of downloading file(I have set simple CSV file)
    fp.setPreference("browser.helperApps.neverAsk.saveToDisk","text/csv");

According to the file type which is being downloaded, You need to specify content types.

You can specify multiple content-types separated with ' ; '

e.g:

    fp.setPreference("browser.helperApps.neverAsk.saveToDisk","text/csv;application/vnd.ms-excel;application/msword");

No.

If the user is sophisticated or determined enough to:

1. Open the Excel VBA editor
2. Use the object browser to see the list of all sheets, including VERYHIDDEN ones
3. Change the property of the sheet to VISIBLE or just HIDDEN

then they are probably sophisticated or determined enough to:

1. Search the internet for "remove Excel 2007 project password"
2. Apply the instructions they find.

So what's on this hidden sheet? Proprietary information like price formulas, or client names, or employee salaries? Putting that info in even an hidden tab probably isn't the greatest idea to begin with.

Use:

struct arg_struct *args = malloc(sizeof(struct arg_struct));

And pass this arguments like this:

pthread_create(&tr, NULL, print_the_arguments, (void *)args);

Don't forget free args! ;)

In the ListBox DoubleClick event get the selecteditem(s) member of the listbox, and there you are.

void ListBox1DoubleClick(object sender, EventArgs e)
    {
        MessageBox.Show(string.Format("SelectedItem:\n{0}",listBox1.SelectedItem.ToString()));
    }

Yes. There are methods on the String itself for this.

Note that the result depends on the Locale the JVM is using. Beware, locales is an art in itself.

In my humble opinion the best way is to just add a full day in milliseconds, depending on how you factor your code it can mess up if your on the last day of the month.

for example Feb 28 or march 31.

Here is an example of how i would do it:

var current = new Date(); //'Mar 11 2015' current.getTime() = 1426060964567
var followingDay = new Date(current.getTime() + 86400000); // + 1 day in ms
followingDay.toLocaleDateString();

imo this insures accuracy

here is another example i Do not like that can work for you but not as clean that dose the above

var today = new Date('12/31/2015');
var tomorrow = new Date(today);
tomorrow.setDate(today.getDate()+1);
tomorrow.toLocaleDateString();

imho this === 'POOP'

So some of you have had gripes about my millisecond approach because of day light savings time. So Im going to bash this out. First, Some countries and states do not have Day light savings time. Second Adding exactly 24 hours is a full day. If the date number dose not change once a year but then gets fixed 6 months later i don't see a problem there. But for the purpose of being definite and having to deal with allot the evil Date() i have thought this through and now thoroughly hate Date. So this is my new Approach

var dd = new Date(); // or any date and time you care about 
var dateArray =  dd.toISOString().split('T')[0].split('-').concat( dd.toISOString().split('T')[1].split(':') );
// ["2016", "07", "04", "00", "17", "58.849Z"] at Z 

Now for the fun part!

var date = { 
    day: dateArray[2],
    month: dateArray[1],
    year: dateArray[0],
    hour: dateArray[3],
    minutes: dateArray[4],
    seconds:dateArray[5].split('.')[0],
    milliseconds: dateArray[5].split('.')[1].replace('Z','')
}

now we have our Official Valid international Date Object clearly written out at Zulu meridian. Now to change the date

  dd.setDate(dd.getDate()+1); // this gives you one full calendar date forward
  tomorrow.setDate(dd.getTime() + 86400000);// this gives your 24 hours into the future. do what you want with it.

The -i option streams the edited content into a new file and then renames it behind the scenes, anyway.

Example:

sed -i 's/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g' filename

and

sed -i '' 's/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g' filename

on macOS.

Use the somewhat hidden security feature:

pip install requests[security] or pip install pyOpenSSL ndg-httpsclient pyasn1

Both commands install following extra packages:

• pyOpenSSL
• cryptography
• idna

Please note that this is not required for python-2.7.9+.

If pip install fails with errors, check whether you have required development packages for libffi, libssl and python installed in your system using distribution's package manager:

• Debian/Ubuntu - python-dev libffi-dev libssl-dev packages.

• Fedora - openssl-devel python-devel libffi-devel packages.

Distro list above is incomplete.

Workaround (see the original answer by @TomDotTom):

In case you cannot install some of the required development packages, there's also an option to disable that warning:

import requests.packages.urllib3
requests.packages.urllib3.disable_warnings()

If your pip itself is affected by InsecurePlatformWarning and cannot install anything from PyPI, it can be fixed with this step-by-step guide to deploy extra python packages manually.

If you only need precision to the second, you can use the builtin $SECONDS variable, which counts the number of seconds that the shell has been running.

    echo "This run took $duration seconds"

I'm using Tomcat through XAMPP which might have been the cause of this problem. When I changed appBase="C:/Java Project/", for example, I kept getting "This localhost page can't be found" in the browser.

I had to add a folder called ROOT inside the Java Project folder and then it worked. Any files you're working on have to be inside this ROOT folder but you need to leave appBase="C:/Java Project/" as changing it to appBase="C:/Java Project/ROOT" will cause "This localhost page can't be found" to be displayed again.

Maybe needing the ROOT folder is obvious to more experienced Java developers but it wasn't for me so hopefully this helps anyone else encountering the same problem.

Android Studio automatically creates a Gradle wrapper in the root of your project, which is how it invokes Gradle. The wrapper is basically a script that calls through to the actual Gradle binary and allows you to keep Gradle up to date, which makes using version control easier. To run a Gradle command, you can simply use the gradlew script found in the root of your project (or gradlew.bat on Windows) followed by the name of the task you want to run. For instance, to build a debug version of your Android application, you can run ./gradlew assembleDebug from the root of your repository. In a default project setup, the resulting apk can then be found in app/build/outputs/apk/app-debug.apk. On a *nix machine, you can also just run find . -name '*.apk' to find it, if it's not there.

Since Steve Tjoa's answer always pops up first and mostly lonely when I search for multiple y-axes at Google, I decided to add a slightly modified version of his answer. This is the approach from this matplotlib example.

Reasons:

• His modules sometimes fail for me in unknown circumstances and cryptic intern errors.
• I don't like to load exotic modules I don't know (mpl_toolkits.axisartist, mpl_toolkits.axes_grid1).
• The code below contains more explicit commands of problems people often stumble over (like single legend for multiple axes, using viridis, ...) rather than implicit behavior.

import matplotlib.pyplot as plt 

# Create figure and subplot manually
# fig = plt.figure()
# host = fig.add_subplot(111)

# More versatile wrapper
fig, host = plt.subplots(figsize=(8,5)) # (width, height) in inches
# (see https://matplotlib.org/3.3.3/api/_as_gen/matplotlib.pyplot.subplots.html)
    
par1 = host.twinx()
par2 = host.twinx()
    
host.set_xlim(0, 2)
host.set_ylim(0, 2)
par1.set_ylim(0, 4)
par2.set_ylim(1, 65)
    
host.set_xlabel("Distance")
host.set_ylabel("Density")
par1.set_ylabel("Temperature")
par2.set_ylabel("Velocity")

color1 = plt.cm.viridis(0)
color2 = plt.cm.viridis(0.5)
color3 = plt.cm.viridis(.9)

p1, = host.plot([0, 1, 2], [0, 1, 2],    color=color1, label="Density")
p2, = par1.plot([0, 1, 2], [0, 3, 2],    color=color2, label="Temperature")
p3, = par2.plot([0, 1, 2], [50, 30, 15], color=color3, label="Velocity")

lns = [p1, p2, p3]
host.legend(handles=lns, loc='best')

# right, left, top, bottom
par2.spines['right'].set_position(('outward', 60))

# no x-ticks                 
par2.xaxis.set_ticks([])

# Sometimes handy, same for xaxis
#par2.yaxis.set_ticks_position('right')

# Move "Velocity"-axis to the left
# par2.spines['left'].set_position(('outward', 60))
# par2.spines['left'].set_visible(True)
# par2.yaxis.set_label_position('left')
# par2.yaxis.set_ticks_position('left')

host.yaxis.label.set_color(p1.get_color())
par1.yaxis.label.set_color(p2.get_color())
par2.yaxis.label.set_color(p3.get_color())

# Adjust spacings w.r.t. figsize
fig.tight_layout()
# Alternatively: bbox_inches='tight' within the plt.savefig function 
#                (overwrites figsize)

# Best for professional typesetting, e.g. LaTeX
plt.savefig("pyplot_multiple_y-axis.pdf")
# For raster graphics use the dpi argument. E.g. '[...].png", dpi=200)'

For IntelliJ IDEA 2017.2 I did the following to fix this issue: Go to your project structure Now go to SDKs under platform settings and click the green add button. Add your JDK path. In my case it was this path C:\Program Files\Java\jdk1.8.0_144 Now Just go Project under Project settings and select the project SDK.

The following sequence of commands does remove every name from the current module:

>>> import sys
>>> sys.modules[__name__].__dict__.clear()

I doubt you actually DO want to do this, because "every name" includes all built-ins, so there's not much you can do after such a total wipe-out. Remember, in Python there is really no such thing as a "variable" -- there are objects, of many kinds (including modules, functions, class, numbers, strings, ...), and there are names, bound to objects; what the sequence does is remove every name from a module (the corresponding objects go away if and only if every reference to them has just been removed).

Maybe you want to be more selective, but it's hard to guess exactly what you mean unless you want to be more specific. But, just to give an example:

>>> import sys
>>> this = sys.modules[__name__]
>>> for n in dir():
...   if n[0]!='_': delattr(this, n)
... 
>>>

This sequence leaves alone names that are private or magical, including the __builtins__ special name which houses all built-in names. So, built-ins still work -- for example:

>>> dir()
['__builtins__', '__doc__', '__name__', '__package__', 'n']
>>> 

As you see, name n (the control variable in that for) also happens to stick around (as it's re-bound in the for clause every time through), so it might be better to name that control variable _, for example, to clearly show "it's special" (plus, in the interactive interpreter, name _ is re-bound anyway after every complete expression entered at the prompt, to the value of that expression, so it won't stick around for long;-).

Anyway, once you have determined exactly what it is you want to do, it's not hard to define a function for the purpose and put it in your start-up file (if you want it only in interactive sessions) or site-customize file (if you want it in every script).

        if (card1.getRarity() < card2.getRarity()) {
            return 1;

However, if card2.getRarity() is less than card1.getRarity() you might not return -1.

You similarly miss other cases. I would do this, you can change around depending on your intent:

public int compareTo(Object o) {    
    if(this == o){
        return 0;
    }

    CollectionItem item = (CollectionItem) o;

    Card card1 = CardCache.getInstance().getCard(cardId);
    Card card2 = CardCache.getInstance().getCard(item.getCardId());
    int comp=card1.getSet() - card2.getSet();
    if (comp!=0){
        return comp;
    }
    comp=card1.getRarity() - card2.getRarity();
    if (comp!=0){
        return comp;
    }
    comp=card1.getSet() - card2.getSet();
    if (comp!=0){
        return comp;
    }   
    comp=card1.getId() - card2.getId();
    if (comp!=0){
        return comp;
    }   
    comp=card1.getCardType() - card2.getCardType();

    return comp;

    }
}

'1.0-0' will give you zero decimal places i.e. no decimals. e.g.$500

some applications will treat "localhost" specially. the mysql client will treat localhost as a request to connect to the local unix domain socket instead of using tcp to connect to the server on 127.0.0.1. This may be faster, and may be in a different authentication zone.

I don't know of other apps that treat localhost differently than 127.0.0.1, but there probably are some.

It's just the incorrect lines of code you were trying to execute..

1. You need to turn off your antivirus (if have).
2. Restart Jupyter Notebook.
3. Copy your code then delete the cell you were working on.
4. Rewrite code and make sure you are not doing any mistakes.
5. Find the missed/wrong lines of code specially increment operators and correct them.

INSERT INTO t1 (a,b,c) VALUES (1,2,3),(4,5,6)
ON DUPLICATE KEY UPDATE c=VALUES(a)+VALUES(b);

You can read the tutorial below here :

https://mariadb.com/kb/en/library/insert-on-duplicate-key-update/

http://www.mysqltutorial.org/mysql-insert-or-update-on-duplicate-key-update/

@glglgl already explained why what you were trying to do was not working. Actually, if you are really aiming at defining a variable in a header, you can trick using some preprocessor directives:

file1.c:

#include <stdio.h>

#define DEFINE_I
#include "global.h"

int main()
{
    printf("%d\n",i);
    foo();
    return 0;
}

file2.c:

#include <stdio.h>
#include "global.h"

void foo()
{
    i = 54;
    printf("%d\n",i);
}

global.h:

#ifdef DEFINE_I
int i = 42;
#else
extern int i;
#endif

void foo();

In this situation, i is only defined in the compilation unit where you defined DEFINE_I and is declared everywhere else. The linker does not complain.

I have seen this a couple of times before where an enum was declared in a header, and just below was a definition of a char** containing the corresponding labels. I do understand why the author preferred to have that definition in the header instead of putting it into a specific source file, but I am not sure whether the implementation is so elegant.

Might be a very late answer, but this is good and simple.

select * from table_name order by id desc limit 5

This query will return a set of last 5 values(last 5 rows) you 've inserted in your table

Following code shows how to upload a file to a SFTP server using our Rebex SFTP component.

// create client, connect and log in 
Sftp client = new Sftp();
client.Connect(hostname);
client.Login(username, password);

// upload the 'test.zip' file to the current directory at the server 
client.PutFile(@"c:\data\test.zip", "test.zip");

client.Disconnect();

You can write a complete communication log to a file using a LogWriter property as follows. Examples output (from FTP component but the SFTP output is similar) can be found here.

client.LogWriter = new Rebex.FileLogWriter(
   @"c:\temp\log.txt", Rebex.LogLevel.Debug); 

or intercept the communication using events as follows:

Sftp client = new Sftp();
client.CommandSent += new SftpCommandSentEventHandler(client_CommandSent);
client.ResponseRead += new SftpResponseReadEventHandler(client_ResponseRead);
client.Connect("sftp.example.org");

//... 
private void client_CommandSent(object sender, SftpCommandSentEventArgs e)
{
    Console.WriteLine("Command: {0}", e.Command);
}

private void client_ResponseRead(object sender, SftpResponseReadEventArgs e)
{
    Console.WriteLine("Response: {0}", e.Response);
}

• :map does nvo == normal + (visual + select) + operator pending
• :map! does ic == insert + command-line mode

as stated on help map-modes tables.

So: map does not map to all modes.

To map to all modes you need both :map and :map!.

Java 6 has a default embedded http server.

By the way, if you plan to have a rest web service, here is a simple example using jersey.

In my machine which is ubuntu 14.04 with python 2.7 installed, if I go here,

/usr/local/lib/python2.7/dist-packages/nltk/

there is a file called

VERSION.

If I do a cat VERSION it prints 3.1, which is the NLTK version installed.

I use a solution that is similar to that of David above, but with an additional twist if some rows should be excluded from the count. This assumes that [UserAccountKey] is never null.

-- subtract an extra 1 if null was ranked within the partition,
-- which only happens if there were rows where [Include] <> 'Y'
dense_rank() over (
  partition by [Mth] 
  order by case when [Include] = 'Y' then [UserAccountKey] else null end asc
) 
+ dense_rank() over (
  partition by [Mth] 
  order by case when [Include] = 'Y' then [UserAccountKey] else null end desc
)
- max(case when [Include] = 'Y' then 0 else 1 end) over (partition by [Mth])
- 1

An SQL Fiddle with an extended example can be found here.

for i in range(10,0,-1):
    print i,

The range() function will include the first value and exclude the second.

Return a FileResult or FileStreamResult from your action, depending on whether the file exists or you create it on the fly.

Just an update on more current OS's (Vista, Win7, etc.) - the temp file path has changed may be different based on several variables. The items below are not definitive, however, they are a few I have encountered:

"temp" environment variable setting - then it would be:

%temp%\Temporary ASP.NET Files

Permissions and what application/process (VS, IIS, IIS Express) is running the .Net compiler. Accessing the C:\WINDOWS\Microsoft.NET\Framework folders requires elevated permissions and if you are not developing under an account with sufficient permissions then this folder might be used:

c:\Users\[youruserid]\AppData\Local\Temp\Temporary ASP.NET Files

There are also cases where the temp folder can be set via config for a machine or site specific using this:

<compilation tempDirectory="d:\MyTempPlace" />

I even have a funky setup at work where we don't run Admin by default, plus the IT guys have login scripts that set %temp% and I get temp files in 3 different locations depending on what is compiling things! And I'm still not certain about how these paths get picked....sigh.

Still, dthrasher is correct, you can just delete these and VS and IIS will just recompile them as needed.

Here's one generalized from something I just used. I'm posting it since it's a very simple example, and it demonstrates a practical use case along with default arguments:

#include <vector>

template <class T> class Alloc final { /*...*/ };

template <template <class T> class allocator=Alloc> class MyClass final {
  public:
    std::vector<short,allocator<short>> field0;
    std::vector<float,allocator<float>> field1;
};

Android Market requires you to sign all apps you publish with a certificate, using a public/private key mechanism (the certificate is signed with your private key). This provides a layer of security that prevents, among other things, remote attackers from pushing malicious updates to your application to market (all updates must be signed with the same key).

From The App-Signing Guide of the Android Developer's site:

In general, the recommended strategy for all developers is to sign all of your applications with the same certificate, throughout the expected lifespan of your applications. There are several reasons why you should do so...

Using the same key has a few benefits - One is that it's easier to share data between applications signed with the same key. Another is that it allows multiple apps signed with the same key to run in the same process, so a developer can build more "modular" applications.

You can also use an object-oriented path with pathlib (available as a standard library as of Python 3.4):

from pathlib import Path

start_path = Path('/my/root/directory')
final_path = start_path / 'in' / 'here'

Could you use dircmp ?

On your Main form

1. Set KeyPreview to True

2. Add KeyDown event handler with the following code

   private void MainForm_KeyDown(object sender, KeyEventArgs e)
   {
       if (e.Control && e.KeyCode == Keys.N)
       {
           SearchForm searchForm = new SearchForm();
           searchForm.Show();
       }
   }
   

Error 1064 often occurs when missing DELIMITER around statement like : create function, create trigger.. Make sure to add DELIMITER $$ before each statement and end it with $$ DELIMITER like this:

You cannot upload like this.

You need a physical path exactly like in your local

C:/Users/puneet verma/Downloads/

What you can do is create some local path where your server is working. Hence you can store and retrieve the file. If you bought some domain from any websites there will be path to upload the files. You create these variable as static constant and use it based on the server you are working (Local/Website).

Virtualenv is your friend

Even if you want to add a package to your primary install, it's still best to do it in a virtual environment first, to ensure compatibility with your other packages. However, if you get familiar with virtualenv, you'll probably find there's really no reason to install anything in your base install.

On Linux, I often use curl with the --head parameter. It is available for several operating systems, including Windows.

System Preferences => Keyboard => Key Repeat Rate

This situation isn't in any way different from the standard Java. You can use the standard way to stop a thread:

class WorkerThread extends Thread {
    volatile boolean running = true;

    public void run() {
        // Do work...
        if (!running) return;
        //Continue doing the work
    }
}

The main idea is to check the value of the field from time to time. When you need to stop your thread, you set running to false. Also, as Chris has pointed out, you can use the interruption mechanism.

By the way, when you use AsyncTask, your apporach won't differ much. The only difference is that you will have to call isCancel() method from your task instead of having a special field. If you call cancel(true), but don't implement this mechanism, the thread still won't stop by itself, it will run to the end.

You need to give height for the parent element too! Check out this fiddle.

CSS:

html, body {height: 100%;}

#content, .container-fluid, .span9
{
    border: 1px solid #000;
    overflow-y:auto;
    height:100%;
}?

JavaScript (using jQuery) Way:

$(document).ready(function(){
    $(window).resize(function(){
        $(".fullheight").height($(document).height());
    });
});

I guess you can do this in 5 minute without any further IP/port forwarding, for presenting your local websites temporary.

All you need to do it, go to http://ngrok.com Download small tool extract and run that tool as administrator

Enter command

How do I access/share xampp or localhost website from another computer

Try to connect to repositroy with url: http://github.com/<user>/<project>.git (http except https)

In your case you should clone like this:

git clone http://github.com/<user>/<project>.git

In python, you can put ‘j’ or ‘J’ after a number to make it imaginary, so you can write complex literals easily:

>>> 1j
1j
>>> 1J
1j
>>> 1j * 1j
(-1+0j)

The ‘j’ suffix comes from electrical engineering, where the variable ‘i’ is usually used for current. (Reasoning found here.)

The type of a complex number is complex, and you can use the type as a constructor if you prefer:

>>> complex(2,3)
(2+3j)

A complex number has some built-in accessors:

>>> z = 2+3j
>>> z.real
2.0
>>> z.imag
3.0
>>> z.conjugate()
(2-3j)

Several built-in functions support complex numbers:

>>> abs(3 + 4j)
5.0
>>> pow(3 + 4j, 2)
(-7+24j)

The standard module cmath has more functions that handle complex numbers:

>>> import cmath
>>> cmath.sin(2 + 3j)
(9.15449914691143-4.168906959966565j)

The best solution is to reconfigure the XAMPP Apache server to listen and use different port numbers. Here is how you do it:

1) First, you need to open the Apache “httpd.conf” file and configure it to use/listen on a new port no. To open httpd.conf file, click the “Config” button next to Apache “Start” and “Admin” buttons. In the popup menu that opens, click and open httpd.conf

2) Within the httpd.conf file search for “listen”. You’ll find two rows with something like:

#Listen 12.34.56.78:80
Listen 80

Change the port no to a port no. of your choice (e.g. port 1234) like below

#Listen 12.34.56.78:1234
Listen 1234

3) Next, in the same httpd.conf file look for “ServerName localhost:” Set it to the new port no.

ServerName localhost:1234

4) Save and close the httpd.conf file.

5) Now click the Apache config button again and open the “httpd-ssl.conf” file.

6) In the httpd-ssl.conf file, look for “Listen” again. You may find:

Listen 443

Change it to listen on a new port no of your choice. Say like:

Listen 1443

7) In the same httpd-ssl.conf file find another line that says <VirtualHost _default_:443>. Change this to your new port no. (like 1443)

8) Also in the same httpd-ssl.conf you can find another line defining the port no. For that look for “ServerName”. you might find something like:

ServerName www.example.com:443 or  ServerName localhost:433

Change this ServerName to your new port no.

8) Save and close the httpd-ssl.conf file.

9) Finally, there’s just one more place you should change the port no. For that, click and open the “Config” button of your XAMPP Control Panel. Then click the, “Service and Port Settings” button. Within it, click the “Apache” tab and enter and save the new port nos in the “main port” and “SSL port” boxes. Click save and close the config boxes.

That should do the trick. Now “Start” Apache and if everything goes well, your Apache server should start up.

You will also see the Apache Port/s no in the XAMPP control panel has change to the new port IDs you set.

You don't need HttpServletResponse to set a header on the response. You can do it using javax.ws.rs.core.Response. Just make your method to return Response instead of entity:

return Response.ok(entity).header("Content-Disposition", "attachment; filename=\"" + fileName + "\"").build()

If you still want to use HttpServletResponse you can get it either injected to one of the class fields, or using property, or to method parameter:

@Path("/resource")
class MyResource {

  // one way to get HttpServletResponse
  @Context
  private HttpServletResponse anotherServletResponse;

  // another way
  Response myMethod(@Context HttpServletResponse servletResponse) {
      // ... code
  }
}

This was my data

## list of columns 
l1 = ['PM2.5', 'PM10', 'TEMP', 'BP', ' RH', 'WS','CO', 'O3', 'Nox', 'SO2'] 

for i in l1:
 for j in range(0, 8431): #rows = 8431
   df[i][j] = int(df[i][j])

I recommend you to use this only with small data. This code has complexity of O(n^2).

I think this is the easiest way to do it.

static bool IsPrime(int number)
{
   for (int i = 2; i <= number/2; i++)
       if (number % i == 0)
           return false;
    return true;
}

Shorter way is do it as follows:

private char[][] table = {{'1', '2', '3'}, {'4', '5', '6'}, {'7', '8', '9'}};

The answer from @KM is good as far as it goes but fails to fully follow up on one of his early bits of advice;

..., ignore compact code, ignore worrying about repeating code, ...

If you are looking to achieve the best performance then you should write a bespoke query for each possible combination of optional criteria. This might sound extreme, and if you have a lot of optional criteria then it might be, but performance is often a trade-off between effort and results. In practice, there might be a common set of parameter combinations that can be targeted with bespoke queries, then a generic query (as per the other answers) for all other combinations.

CREATE PROCEDURE spDoSearch
    @FirstName varchar(25) = null,
    @LastName varchar(25) = null,
    @Title varchar(25) = null
AS
BEGIN

    IF (@FirstName IS NOT NULL AND @LastName IS NULL AND @Title IS NULL)
        -- Search by first name only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            FirstName = @FirstName

    ELSE IF (@FirstName IS NULL AND @LastName IS NOT NULL AND @Title IS NULL)
        -- Search by last name only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            LastName = @LastName

    ELSE IF (@FirstName IS NULL AND @LastName IS NULL AND @Title IS NOT NULL)
        -- Search by title only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            Title = @Title

    ELSE IF (@FirstName IS NOT NULL AND @LastName IS NOT NULL AND @Title IS NULL)
        -- Search by first and last name
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            FirstName = @FirstName
            AND LastName = @LastName

    ELSE
        -- Search by any other combination
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
                (@FirstName IS NULL OR (FirstName = @FirstName))
            AND (@LastName  IS NULL OR (LastName  = @LastName ))
            AND (@Title     IS NULL OR (Title     = @Title    ))

END

The advantage of this approach is that in the common cases handled by bespoke queries the query is as efficient as it can be - there's no impact by the unsupplied criteria. Also, indexes and other performance enhancements can be targeted at specific bespoke queries rather than trying to satisfy all possible situations.

And depending on the Spyder version you can change the interpreter in the Python interpreter section (Spyder 3.x):

or in the advanced Console section (Spyder 2.x):

savedir = r"E:\new_mission _data\test"
filename = r"E:\new_mission _data\test\testing1.png"
img = Image.open(filename)
width, height = img.size
start_pos = start_x, start_y = (0, 0)
cropped_image_size = w, h = (1024,1024)

frame_num = 1
for col_i in range(0, width, w):
    for row_i in range(0, height, h):
        crop = img.crop((col_i, row_i, col_i + w, row_i + h))
        save_to= os.path.join(savedir, "testing_{:02}.png")
        crop.save(save_to.format(frame_num))
        frame_num += 1

Here's a little trick I'm using lately and brings good results. I would like to share with those who have to fight often with VBA.

1.- Implement a public initiation subroutine in each of your custom classes. I call it InitiateProperties throughout all my classes. This method has to accept the arguments you would like to send to the constructor.

2.- Create a module called factory, and create a public function with the word "Create" plus the same name as the class, and the same incoming arguments as the constructor needs. This function has to instantiate your class, and call the initiation subroutine explained in point (1), passing the received arguments. Finally returned the instantiated and initiated method.

Example:

Let's say we have the custom class Employee. As the previous example, is has to be instantiated with name and age.

This is the InitiateProperties method. m_name and m_age are our private properties to be set.

Public Sub InitiateProperties(name as String, age as Integer)

    m_name = name
    m_age = age

End Sub

And now in the factory module:

Public Function CreateEmployee(name as String, age as Integer) as Employee

    Dim employee_obj As Employee
    Set employee_obj = new Employee

    employee_obj.InitiateProperties name:=name, age:=age
    set CreateEmployee = employee_obj

End Function

And finally when you want to instantiate an employee

Dim this_employee as Employee
Set this_employee = factory.CreateEmployee(name:="Johnny", age:=89)

Especially useful when you have several classes. Just place a function for each in the module factory and instantiate just by calling factory.CreateClassA(arguments), factory.CreateClassB(other_arguments), etc.

EDIT

As stenci pointed out, you can do the same thing with a terser syntax by avoiding to create a local variable in the constructor functions. For instance the CreateEmployee function could be written like this:

Public Function CreateEmployee(name as String, age as Integer) as Employee

    Set CreateEmployee = new Employee
    CreateEmployee.InitiateProperties name:=name, age:=age

End Function

Which is nicer.

One Good solution is to restart the PC, this will make the right entry in the Registry of the PC. Restarting solves my problem

I prefer this way, not using a cell but a range

    Dim cell_to_test As Range, cells_changed As Range

    Set cells_changed = Target(1, 1)
    Set cell_to_test = Range( RANGE_OF_CELLS_TO_DETECT )

    If Not Intersect(cells_changed, cell_to_test) Is Nothing Then 
       Macro
    End If

In C# (Sharp), you can make an empty character as '\0'. Maybe you can do this:

String.prototype.replaceAt = function (index, char) {
return this.substr(0, index) + char + this.substr(index + char.length);
}
mystring.replaceAt(4, '\0')

Search on google or surf on the interent and check if javascript allows you to make empty characters, like C# does. If yes, then learn how to do it, and maybe the replaceAt function will work at last, and you'll achieve what you want!

Finally that 'r' character will be removed!

You could just pass an anchor tag without an href property, and use jQuery to do the required action:

<a class="foo">bar</a>

try this:

import os

os.uname()

and you can make it :

info=os.uname()
info[0]
info[1]

parameter type 'support.ACTInterface' is less accessible than method    
'support.clients.clients(support.ACTInterface)' 

The error says 'support.ACTInterface' is less accessible because you have made the interface as private, at least make it internal or make it public.

Not orthodox, but it works for me sometimes; set your comment as another attribute:

Skip lists are pretty neat.

Wikipedia
A skip list is a probabilistic data structure, based on multiple parallel, sorted linked lists, with efficiency comparable to a binary search tree (order log n average time for most operations).

They can be used as an alternative to balanced trees (using probalistic balancing rather than strict enforcement of balancing). They are easy to implement and faster than say, a red-black tree. I think they should be in every good programmers toolchest.

If you want to get an in-depth introduction to skip-lists here is a link to a video of MIT's Introduction to Algorithms lecture on them.

Also, here is a Java applet demonstrating Skip Lists visually.

Try With Different Logic. You can use bellow code for check all four(4) condition for validation like not null, not blank, not undefined and not zero only use this code (!(!(variable))) in javascript and jquery.

function myFunction() {
    var data;  //The Values can be like as null, blank, undefined, zero you can test

    if(!(!(data)))
    {
        alert("data "+data);
    } 
    else 
    {
        alert("data is "+data);
    }
}

Two ways. Either create a button and style it so it looks like a link with css, or create a link and use onclick="this.closest('form').submit();return false;".

You're looking for a non-greedy (or lazy) match. To get a non-greedy match in regular expressions you need to use the modifier ? after the quantifier. For example you can change .* to .*?.

By default grep doesn't support non-greedy modifiers, but you can use grep -P to use the Perl syntax.

You can use .prop() with tagName as the name of the property that you want to get:

$("#elementId").prop('tagName'); 

The simplest way to modify all files of a project at once (batch) is through Line Endings Unify package:

1. Ctrl+Shift+P type inst + choose Install Package.
2. Type line end + choose Line Endings Unify.
3. Once installed, Ctrl+Shift+P + type end + choose Line Endings Unify.

4. OR (instead of 3.) copy:

   {
    "keys": ["ctrl+alt+l"],
    "command": "line_endings_unify"
   },
   

   to the User array (right pane, after the opening [) in Preferences -> KeyBindings + press Ctrl+Alt+L.

As mentioned in another answer:

• The Carriage Return (CR) character (0x0D, \r) [...] Early Macintosh operating systems (OS-9 and earlier).

• The Line Feed (LF) character (0x0A, \n) [...] UNIX based systems (Linux, Mac OSX)

• The End of Line (EOL) sequence (0x0D 0x0A, \r\n) [...] (non-Unix: Windows, Symbian OS).

If you have node_modules, build or other auto-generated folders, delete them before running the package.

When you run the package:

1. you are asked at the bottom to choose which file extensions to search through a comma separated list (type the only ones you need to speed up the replacements, e.g. js,jsx).
2. then you are asked which Input line ending to use, e.g. if you need LF type \n.
3. press ENTER and wait until you see an alert window with LineEndingsUnify Complete.

Do you mean inline functions in the C++ sense? In which the contents of a normal function are automatically copied inline into the callsite? The end effect being that no function call actually happens when calling a function.

Example:

inline int Add(int left, int right) { return left + right; }

If so then no, there is no C# equivalent to this.

Or Do you mean functions that are declared within another function? If so then yes, C# supports this via anonymous methods or lambda expressions.

Example:

static void Example() {
  Func<int,int,int> add = (x,y) => x + y;
  var result = add(4,6);  // 10
}

Update: React 16.0 introduced portals through ReactDOM.createPortal link

Update: next versions of React (Fiber: probably 16 or 17) will include a method to create portals: ReactDOM.unstable_createPortal() link

Use portals

Dan Abramov answer first part is fine, but involves a lot of boilerplate. As he said, you can also use portals. I'll expand a bit on that idea.

The advantage of a portal is that the popup and the button remain very close into the React tree, with very simple parent/child communication using props: you can easily handle async actions with portals, or let the parent customize the portal.

What is a portal?

A portal permits you to render directly inside document.body an element that is deeply nested in your React tree.

The idea is that for example you render into body the following React tree:

<div className="layout">
  <div className="outside-portal">
    <Portal>
      <div className="inside-portal">
        PortalContent
      </div>
    </Portal>
  </div>
</div>

And you get as output:

<body>
  <div class="layout">
    <div class="outside-portal">
    </div>
  </div>
  <div class="inside-portal">
    PortalContent
  </div>
</body>

The inside-portal node has been translated inside <body>, instead of its normal, deeply-nested place.

When to use a portal

A portal is particularly helpful for displaying elements that should go on top of your existing React components: popups, dropdowns, suggestions, hotspots

Why use a portal

No z-index problems anymore: a portal permits you to render to <body>. If you want to display a popup or dropdown, this is a really nice idea if you don't want to have to fight against z-index problems. The portal elements get added do document.body in mount order, which means that unless you play with z-index, the default behavior will be to stack portals on top of each others, in mounting order. In practice, it means that you can safely open a popup from inside another popup, and be sure that the 2nd popup will be displayed on top of the first, without having to even think about z-index.

In practice

Most simple: use local React state: if you think, for a simple delete confirmation popup, it's not worth to have the Redux boilerplate, then you can use a portal and it greatly simplifies your code. For such a use case, where the interaction is very local and is actually quite an implementation detail, do you really care about hot-reloading, time-traveling, action logging and all the benefits Redux brings you? Personally, I don't and use local state in this case. The code becomes as simple as:

class DeleteButton extends React.Component {
  static propTypes = {
    onDelete: PropTypes.func.isRequired,
  };

  state = { confirmationPopup: false };

  open = () => {
    this.setState({ confirmationPopup: true });
  };

  close = () => {
    this.setState({ confirmationPopup: false });
  };

  render() {
    return (
      <div className="delete-button">
        <div onClick={() => this.open()}>Delete</div>
        {this.state.confirmationPopup && (
          <Portal>
            <DeleteConfirmationPopup
              onCancel={() => this.close()}
              onConfirm={() => {
                this.close();
                this.props.onDelete();
              }}
            />
          </Portal>
        )}
      </div>
    );
  }
}

Simple: you can still use Redux state: if you really want to, you can still use connect to choose whether or not the DeleteConfirmationPopup is shown or not. As the portal remains deeply nested in your React tree, it is very simple to customize the behavior of this portal because your parent can pass props to the portal. If you don't use portals, you usually have to render your popups at the top of your React tree for z-index reasons, and usually have to think about things like "how do I customize the generic DeleteConfirmationPopup I built according to the use case". And usually you'll find quite hacky solutions to this problem, like dispatching an action that contains nested confirm/cancel actions, a translation bundle key, or even worse, a render function (or something else unserializable). You don't have to do that with portals, and can just pass regular props, since DeleteConfirmationPopup is just a child of the DeleteButton

Conclusion

Portals are very useful to simplify your code. I couldn't do without them anymore.

Note that portal implementations can also help you with other useful features like:

• Accessibility
• Espace shortcuts to close the portal
• Handle outside click (close portal or not)
• Handle link click (close portal or not)
• React Context made available in portal tree

react-portal or react-modal are nice for popups, modals, and overlays that should be full-screen, generally centered in the middle of the screen.

react-tether is unknown to most React developers, yet it's one of the most useful tools you can find out there. Tether permits you to create portals, but will position automatically the portal, relative to a given target. This is perfect for tooltips, dropdowns, hotspots, helpboxes... If you have ever had any problem with position absolute/relative and z-index, or your dropdown going outside of your viewport, Tether will solve all that for you.

You can, for example, easily implement onboarding hotspots, that expands to a tooltip once clicked:

Real production code here. Can't be any simpler :)

<MenuHotspots.contacts>
  <ContactButton/>
</MenuHotspots.contacts>

Edit: just discovered react-gateway which permits to render portals into the node of your choice (not necessarily body)

Edit: it seems react-popper can be a decent alternative to react-tether. PopperJS is a library that only computes an appropriate position for an element, without touching the DOM directly, letting the user choose where and when he wants to put the DOM node, while Tether appends directly to the body.

Edit: there's also react-slot-fill which is interesting and can help solve similar problems by allowing to render an element to a reserved element slot that you put anywhere you want in your tree

• The children of a row-flexbox container automatically fill the container's vertical space.

• Specify flex: 1; for a child if you want it to fill the remaining horizontal space:

.wrapper {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  align-items: stretch;_x000D_
  width: 100%;_x000D_
  height: 5em;_x000D_
  background: #ccc;_x000D_
}_x000D_
.wrapper > .left_x000D_
{_x000D_
  background: #fcc;_x000D_
}_x000D_
.wrapper > .right_x000D_
{_x000D_
  background: #ccf;_x000D_
  flex: 1; _x000D_
}

<div class="wrapper">_x000D_
  <div class="left">Left</div>_x000D_
  <div class="right">Right</div>_x000D_
</div>

• Specify flex: 1; for both children if you want them to fill equal amounts of the horizontal space:

.wrapper {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  align-items: stretch;_x000D_
  width: 100%;_x000D_

  background: #fcc;_x000D_
}_x000D_
.wrapper > .right_x000D_

  background: #ccf;_x000D_
}

<div class="wrapper">_x000D_
  <div class="left">Left</div>_x000D_
  <div class="right">Right</div>_x000D_
</div>

I've found another easy way to deal with this problem, you just need the attribute " connectToSortable:" to draggable like as below code:

$("#a1,#a2").draggable({
        connectToSortable: "#b,#a",
        revert: 'invalid',
    });

PS: More detail and example
How to move Draggable objects between source area and target area with jQuery

If you want to overwrite only one file:

git fetch
git checkout origin/master <filepath>

If you want to overwrite all changed files:

git fetch
git reset --hard origin/master

(This assumes that you're working on master locally and you want the changes on the origin's master - if you're on a branch, substitute that in instead.)

All you need to do is run

pip install /opt/mypackage

and pip will search /opt/mypackage for a setup.py, build a wheel, then install it.

The problem with using the -e flag for pip install as suggested in the comments and this answer is that this requires that the original source directory stay in place for as long as you want to use the module. It's great if you're a developer working on the source, but if you're just trying to install a package, it's the wrong choice.

Alternatively, you don't even need to download the repo from Github at all. pip supports installing directly from git repos using a variety of protocols including HTTP, HTTPS, and SSH, among others. See the docs I linked to for examples.

This is an old question, but no one responded to the question regarding centering text in a terminal.

/**
 * Centers a string of text in a terminal window
 *
 * @param string $text The text to center
 * @param string $pad_string If set, the string to pad with (eg. '=' for a nice header)
 *
 * @return string The padded result, ready to echo
 */
function center($text, $pad_string = ' ') {
    $window_size = (int) `tput cols`;
    return str_pad($text, $window_size, $pad_string, STR_PAD_BOTH)."\n";
}

echo center('foo');
echo center('bar baz', '=');

For Query parameters like domain.com/test?format=json&type=mini format, then you can easily receive it via - req.query.

app.get('/test', function(req, res){
  var format = req.query.format,
      type = req.query.type;
});

For a DATE column you can use:

NULLS last:

ORDER BY IFNULL(`myDate`, '9999-12-31') ASC

Blanks last:

ORDER BY IF(`myDate` = '', '9999-12-31', `myDate`) ASC

If using a Mac

1. highlight column
2. copy
3. open terminal.app
4. type pbpaste|sort -u|wc -l

Linux users replace pbpaste with xclip xsel or similar

Windows users, it's possible but would take some scripting... start with http://brianreiter.org/2010/09/03/copy-and-paste-with-clipboard-from-powershell/

git pull is really just a shorthand for git pull <remote> <branchname>, in most cases it's equivalent to git pull origin master. You will need to add another remote and pull explicitly from it. This page describes it in detail:

http://help.github.com/forking/

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

Layers are conceptual entities, and are used to separate the functionality of software system from a logical point of view; when you implement the system you organize these layers using different methods; in this condition we refer to them not as layers but as tiers.

The List<> class does guarantee ordering - things will be retained in the list in the order you add them, including duplicates, unless you explicitly sort the list.

According to MSDN:

...List "Represents a strongly typed list of objects that can be accessed by index."

The index values must remain reliable for this to be accurate. Therefore the order is guaranteed.

You might be getting odd results from your code if you're moving the item later in the list, as your Remove() will move all of the other items down one place before the call to Insert().

Can you boil your code down to something small enough to post?

I had the same issue when installing the "Twisted" library and solved it by running the following command on Ubuntu 16.04 (Xenial Xerus):

sudo apt-get install python-setuptools python-dev build-essential

You should use the background attribute to give an image to that element, and I would use ::after instead of before, this way it should be already drawn on top of your element.

.Modal:before{
  content: '';
  background:url('blackCarrot.png');
  width: /* width of the image */;
  height: /* height of the image */;
  display: block;
}

I have used this:

document.onkeydown = keyboardDown;
document.onkeyup = keyboardUp;
document.oncontextmenu = function(e){
 var evt = new Object({keyCode:93});
 stopEvent(e);
 keyboardUp(evt);
}
function stopEvent(event){
 if(event.preventDefault != undefined)
  event.preventDefault();
 if(event.stopPropagation != undefined)
  event.stopPropagation();
}
function keyboardDown(e){
 ...
}
function keyboardUp(e){
 ...
}

Then I catch e.keyCode property in those two last functions - if e.keyCode == 93, I know that the user either released the right mouse button or pressed/released the Context Menu key.

Hope it helps.

Based on the accepted answer I created an Extension method as follows:

public static Guid ToGuid(this string aString)
{
    Guid newGuid;

    if (string.IsNullOrWhiteSpace(aString))
    {
        return MagicNumbers.defaultGuid;
    }

    if (Guid.TryParse(aString, out newGuid))
    {
        return newGuid;
    }

    return MagicNumbers.defaultGuid;
}

Where "MagicNumbers.defaultGuid" is just "an empty" all zero Guid "00000000-0000-0000-0000-000000000000".

In my case returning that value as the result of an invalid ToGuid conversion was not a problem.

To get all the elements starting with "jander" you should use:

$("[id^=jander]")

To get those that end with "jander"

$("[id$=jander]")

See also the JQuery documentation

Use the built in collection methods contain and find, which will search by primary ids (instead of array keys). Example:

if ($model->collection->contains($primaryId)) {
    var_dump($model->collection->find($primaryId);
}

contains() actually just calls find() and checks for null, so you could shorten it down to:

if ($myModel = $model->collection->find($primaryId)) {
    var_dump($myModel);
}

Whatever Node.js version you have installed, run its installer again. It asks you to remove Node.js like this:

((1,2,3,4),
 (5,6,7,8),
 (9,0,1,2))

Using tuples instead of lists makes it marginally harder to change the data structure in unwanted ways.

If you are going to do extensive use of those, you are best off wrapping a true number array in a class, so you can define methods and properties on them. (Or, you could NumPy, SciPy, ... if you are going to do your processing with those libraries.)

If you need the checkbox to be submitted with the form but effectively read-only to the user, I recommend setting them to disabled and using javascript to re-enable them when the form is submitted.

This is for two reasons. First and most important, your users benefit from seeing a visible difference between checkboxes they can change and checkboxes which are read-only. Disabled does this.

Second reason is that the disabled state is built into the browser so you need less code to execute when the user clicks on something. This is probably more of a personal preference than anything else. You'll still need some javascript to un-disable these when submitting the form.

It seems easier to me to use some javascript when the form is submitted to un-disable the checkboxes than to use a hidden input to carry the value.

I had the same warning and found that removing an unused @id got rid of the warning. For me it was obvious as the @id was associated with a growing list of textViews linked to a database, so there was a warning for each entry.

yes it's possible to print a string to the console.

#include "stdafx.h"
#include <string>
#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
    string strMytestString("hello world");
    cout << strMytestString;
    return 0;
}

stdafx.h isn't pertinent to the solution, everything else is.

There's much simpler solution today — pem. This tool makes life much easier.

For example, to generate or renew your push notification certificate just enter:

fastlane pem 

and it's done in under a minute. In case you need a sandbox certificate, enter:

fastlane pem --development

And that's pretty it.

With an Android-powered device, you can develop and debug your Android applications just as you would on the emulator.

1. Declare your application as "debuggable" in AndroidManifest.xml.

<application
    android:debuggable="true"
    ... >
    ...
</application>

2. On your handset, navigate to Settings > Security and check Unknown sources

3. Go to Settings > Developer Options and check USB debugging
Note that if Developer Options is invisible you will need to navigate to Settings > About Phone and tap on Build number several times until you are notified that it has been unlocked.

4. Set up your system to detect your device.
Follow the instructions below for your OS:

Windows Users

Install the Google USB Driver from the ADT SDK Manager
(Support for: ADP1, ADP2, Verizon Droid, Nexus One, Nexus S).

For devices not listed above, install an OEM driver for your device

Mac OS X

Your device should automatically work; Go to the next step

Ubuntu Linux

Add a udev rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR{idVendor} property. For a list of vendor IDs, click here. To set up device detection on Ubuntu Linux:

1. Log in as root and create this file: /etc/udev/rules.d/51-android.rules.
2. Use this format to add each vendor to the file:
   SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"
   In this example, the vendor ID is for HTC. The MODE assignment specifies read/write permissions, and GROUP defines which Unix group owns the device node.
3. Now execute: chmod a+r /etc/udev/rules.d/51-android.rules

Note: The rule syntax may vary slightly depending on your environment. Consult the udev documentation for your system as needed. For an overview of rule syntax, see this guide to writing udev rules.

5. Run the project with your connected device.

With Eclipse/ADT: run or debug your application as usual. You will be presented with a Device Chooser dialog that lists the available emulator(s) and connected device(s).

With ADB: issue commands with the -d flag to target your connected device.

Above two answers are correct but didn't work for me.

1. I kept on seeing blank like below for docker container ls
2. then I tried, docker container ls -a and after that it showed all the process previously exited and running.
3. Then docker stop <container id> or docker container stop <container id> didn't work
4. then I tried docker rm -f <container id> and it worked.
5. Now at this I tried docker container ls -a and this process wasn't present.

The Web API basically return 4 type of object: void, HttpResponseMessage, IHttpActionResult, and other strong types. The first version of the Web API returns HttpResponseMessage which is pretty straight forward HTTP response message.

The IHttpActionResult was introduced by WebAPI 2 which is a kind of wrap of HttpResponseMessage. It contains the ExecuteAsync() method to create an HttpResponseMessage. It simplifies unit testing of your controller.

Other return type are kind of strong typed classes serialized by the Web API using a media formatter into the response body. The drawback was you cannot directly return an error code such as a 404. All you can do is throwing an HttpResponseException error.

The cleanest solution is probably to specify your divs as exact children.

Try changing this:

div.rounded div div {
    background: url('bl.gif') no-repeat bottom left;
}

To this:

div.rounded > div > div {
    background: url('bl.gif') no-repeat bottom left;
}

First off: The variables a and b in the loops refer to numpy.ndarray objects.

In the first loop, a = a + 1 is evaluated as follows: the __add__(self, other) function of numpy.ndarray is called. This creates a new object and hence, A is not modified. Afterwards, the variable a is set to refer to the result.

In the second loop, no new object is created. The statement b += 1 calls the __iadd__(self, other) function of numpy.ndarray which modifies the ndarray object in place to which b is referring to. Hence, B is modified.

Alternatively you could update brew by installing it again. (Think I did this as El Capitan changed something)

Note: this is a heavy handed approach that will remove all applications installed via brew!

Try to install brew a fresh and it will tell how to uninstall.

At original time of writing to uninstall:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Edit: As of 2020 to uninstall:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

setup an AT command to run task manager or process explorer as SYSTEM.

AT 12:34 /interactive "C:/procexp.exe"

If process explorer was in your root C drive then this would open it as SYSTEM and you could kill any process without getting any access denied errors. Set this for like a minute in the future, then it will pop up for you.

You are probably looking for System.Guid.NewGuid().

You can redirect by this method also:

return Yii::$app->response->redirect(['user/index', 'id' => 10]);

If you want to send the Header information immediately use with send().This method adds a Location header to the current response.

return Yii::$app->response->redirect(['user/index', 'id' => 10])->send();

If you want the complete URL then use like Url::to(['user/index', 'id' => 302]) with the header of use yii\helpers\Url;.

For more information check Here. Hope this will help someone.

I was facing the same problem and the challenge in my case was to configure Jacoco correctly and to configure the right parameters for Sonar. I will briefly explain, how I finally got SonarQube to display the test results and test coverage correctly.

In your project you need the Jacoco plugin in your pom or parent pom (you already got this). Moreover, you need the maven-surefire-plugin, which is used to display test results. All test reports are automatically generated when you run the maven build. The tricky part is to find the right parameters for Sonar. Not all parameters seem to work with regular expressions and you have to use a comma separated list for those (documentation is not really good in my opinion). Here is the list of parameters I have used (I used them from Bamboo, you might omit the "-D" if you use a sonar.properties file):

-Dsonar.branch.target=master (in newer version of SQ I had to remove this, so that master branch is analyzed correctly; I used auto branch checkbox in bamboo instead)
-Dsonar.working.directory=./target/sonar
-Dsonar.java.binaries=**/target/classes
-Dsonar.sources=./service-a/src,./service-b/src,./service-c/src,[..]
-Dsonar.exclusions=**/data/dto/**
-Dsonar.tests=.
-Dsonar.test.inclusions=**/*Test.java [-> all your tests have to end with "Test"]
-Dsonar.junit.reportPaths=./service-a/target/surefire-reports,./service-b/target/surefire-reports,
./service-c/target/surefire-reports,[..]
-Dsonar.jacoco.reportPaths=./service-a/target/jacoco.exec,./service-b/target/jacoco.exec,
./service-c/target/jacoco.exec,[..]
-Dsonar.projectVersion=${bamboo.buildNumber}
-Dsonar.coverage.exclusions=**/src/test/**,**/common/**
-Dsonar.cpd.exclusions=**/*Dto.java,**/*Entity.java,**/common/**

If you are using Lombok in your project, than you also need a lombok.config file to get the correct code coverage. The lombok.config file is located in the root directory of your project with the following content:

config.stopBubbling = true
lombok.addLombokGeneratedAnnotation = true

In Xcode 6+ you can simply go to Menu > Window > Devices > Simulators and delete a simulator you don't need.

Changing your lists to numpy arrays will do the job!!

import matplotlib.pyplot as plt
from scipy import stats
import numpy as np 

x = np.array([0.46,0.59,0.68,0.99,0.39,0.31,1.09,0.77,0.72,0.49,0.55,0.62,0.58,0.88,0.78]) # x is a numpy array now
y = np.array([0.315,0.383,0.452,0.650,0.279,0.215,0.727,0.512,0.478,0.335,0.365,0.424,0.390,0.585,0.511]) # y is a numpy array now
xerr = [0.01]*15
yerr = [0.001]*15

plt.rc('font', family='serif', size=13)
m, b = np.polyfit(x, y, 1)
plt.plot(x,y,'s',color='#0066FF')
plt.plot(x, m*x + b, 'r-') #BREAKS ON THIS LINE
plt.errorbar(x,y,xerr=xerr,yerr=0,linestyle="None",color='black')
plt.xlabel('$\Delta t$ $(s)$',fontsize=20)
plt.ylabel('$\Delta p$ $(hPa)$',fontsize=20)
plt.autoscale(enable=True, axis=u'both', tight=False)
plt.grid(False)
plt.xlim(0.2,1.2)
plt.ylim(0,0.8)
plt.show()

You can use title. it'll work for just about everything

<div title="Great for making new friends through cooperation.">

<input script=JavaScript type=button title="Click for a compliment" onclick="window.alert('Your hair reminds me of a sunset across a prairie')" value="making you happy">

<table title="Great job working for those who understand the way i feel">

just think of any tag that can be visible to html window and insert a title="whatever tooltip you'd like" inside it's tag and you got yourself a tooltip.

In Visual Studio check

Build => Configuration Manager => Active solution configuration

If it is set to Release rather than Debug no breakpoints will be hit.

UPDATED

For python 3, you should use items() instead of iteritems()

PYTHON 2

for attr, value in k.__dict__.iteritems():
        print attr, value

PYTHON 3

for attr, value in k.__dict__.items():
        print(attr, value)

This will print

'names', [a list with names]
'tweet', [a list with tweet]

The code condition ? statement_A : statement_B is equivalent to

if condition == true
  statement_A
else
  statement_B
end

Actually, it's not possible with axios as of now. The status codes which falls in the range of 2xx only, can be caught in .then().

A conventional approach is to catch errors in the catch() block like below:

axios.get('/api/xyz/abcd')
  .catch(function (error) {
    if (error.response) {
      // Request made and server responded
      console.log(error.response.data);
      console.log(error.response.status);
      console.log(error.response.headers);
    } else if (error.request) {
      // The request was made but no response was received
      console.log(error.request);
    } else {
      // Something happened in setting up the request that triggered an Error
      console.log('Error', error.message);
    }

  });

Another approach can be intercepting requests or responses before they are handled by then or catch.

axios.interceptors.request.use(function (config) {
    // Do something before request is sent
    return config;
  }, function (error) {
    // Do something with request error
    return Promise.reject(error);
  });

// Add a response interceptor
axios.interceptors.response.use(function (response) {
    // Do something with response data
    return response;
  }, function (error) {
    // Do something with response error
    return Promise.reject(error);
  });

In the root web.config for your project, under the system.web node:

<system.web>
    <httpRuntime maxUrlLength="10999" maxQueryStringLength="2097151" />
...

In addition, I had to add this under the system.webServer node or I got a security error for my long query strings:

<system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxUrl="10999" maxQueryString="2097151" />
      </requestFiltering>
    </security>
...

If you want to consider null values equality too, try the following

select column1, column2, 
   case
      when column1 is NULL and column2 is NULL then 'true'  
      when column1=column2 then 'true' 
      else 'false' 
   end 
from table;

Similarly to Jakob's answer, you can use HTML tags. Just a note that the color attribute of font (<font color=...>) is deprecated in HTML5. The following syntax would be HTML5-compliant:

This <span style="color:red">word</span> is not black.

Same caution that Jakob made probably still applies:

Be aware that this will not survive a conversion of the notebook to latex.

This is how you can insert into an identity column:

CREATE TABLE my_table (id INTEGER PRIMARY KEY AUTOINCREMENT, name COLLATE NOCASE);
CREATE TABLE temp_table (name COLLATE NOCASE);

.import predefined/myfile.txt temp_table 
insert into my_table (name) select name from temp_table;

myfile.txt is a file in C:\code\db\predefined\

data.db is in C:\code\db\

myfile.txt contains strings separated by newline character.

If you want to add more columns, it's easier to separate them using the pipe character, which is the default.

I've recently tried Retrofit Library from square, Its great and you can call your rest API very easily. Annotation based configuration allows us to get rid of lot of boiler plate coding.

In addtion to align-self you can also consider auto margin which will do almost the same thing

.container {_x000D_
  background: red;_x000D_
  height: 200px;_x000D_
  flex-direction: column;_x000D_

Randomsubsetsort.

Given an array of n elements, choose each element with probability 1/n, randomize these elements, and check if the array is sorted. Repeat until sorted.

Expected time is left as an exercise for the reader.

The long-term answer is that all output from your PHP scripts should be buffered in variables. This includes headers and body output. Then at the end of your scripts do any output you need.

The very quick fix for your problem will be to add

ob_start();

as the very first thing in your script, if you only need it in this one script. If you need it in all your scripts add it as the very first thing in your header.php file.

This turns on PHP's output buffering feature. In PHP when you output something (do an echo or print) it has to send the HTTP headers at that time. If you turn on output buffering you can output in the script but PHP doesn't have to send the headers until the buffer is flushed. If you turn it on and don't turn it off PHP will automatically flush everything in the buffer after the script finishes running. There really is no harm in just turning it on in almost all cases and could give you a small performance increase under some configurations.

If you have access to change your php.ini configuration file you can find and change or add the following

output_buffering = On

This will turn output buffering out without the need to call ob_start().

To find out more about output buffering check out http://php.net/manual/en/book.outcontrol.php

I think it will help you

<script type="text/javascript">
function isNumberKey(evt) {
    var charCode = (evt.which) ? evt.which : event.keyCode
    if (charCode > 32 && (charCode < 48 || charCode > 57) && (charCode != 45) && (charCode != 43) && (charCode != 40) && (charCode != 41))
        return false;

    return true;
}

here's the simple function to calculate age:

<?php
    function age($birthDate){
      //date in mm/dd/yyyy format; or it can be in other formats as well
      //explode the date to get month, day and year
      $birthDate = explode("/", $birthDate);
      //get age from date or birthdate
      $age = (date("md", date("U", mktime(0, 0, 0, $birthDate[0], $birthDate[1], $birthDate[2]))) > date("md")
        ? ((date("Y") - $birthDate[2]) - 1)
        : (date("Y") - $birthDate[2]));
     return $age;
    }

    ?>

    <?php
    echo age('11/05/1991');
    ?>

If "read its contents into a string" means that the file does not contain characters with code 0, you can also use getdelim() function, that either accepts a block of memory and reallocates it if necessary, or just allocates the entire buffer for you, and reads the file into it until it encounters a specified delimiter or end of file. Just pass '\0' as the delimiter to read the entire file.

This function is available in the GNU C Library, http://www.gnu.org/software/libc/manual/html_mono/libc.html#index-getdelim-994

The sample code might look as simple as

char* buffer = NULL;
size_t len;
ssize_t bytes_read = getdelim( &buffer, &len, '\0', fp);
if ( bytes_read != -1) {
  /* Success, now the entire file is in the buffer */

Use the New Java File classes in Java >=7.

Create the below method and import the necessary libs.

public static void copyFile( File from, File to ) throws IOException {
    Files.copy( from.toPath(), to.toPath() );
} 

Use the created method as below within main:

File dirFrom = new File(fileFrom);
File dirTo = new File(fileTo);

try {
        copyFile(dirFrom, dirTo);
} catch (IOException ex) {
        Logger.getLogger(TestJava8.class.getName()).log(Level.SEVERE, null, ex);
}

NB:- fileFrom is the file that you want to copy to a new file fileTo in a different folder.

SWIFT 4 with extension

set:

// set button label for all states
extension UIButton {
    public func setAllStatesTitle(_ newTitle: String){
        self.setTitle(newTitle, for: .normal)
        self.setTitle(newTitle, for: .selected)
        self.setTitle(newTitle, for: .disabled)

and use:

yourBtn.setAllStatesTitle("btn title")

A much more simple solution (thanks to http://daniel.fone.net.nz/blog/2014/12/01/fixing-connection-errors-after-upgrading-postgres/) . I had upgraded to postgres 9.4. In my case, all I needed to do (after a day of googling and not succeeding)

gem uninstall pg
gem uninstall activerecord-postgresql-adapter
bundle install

Restart webrick, and done!

Even simpler, have it labeled in each li tag's class attribute and have jquery to loop through each li to initialize the accordion.

So if you are using Moq, and want to mock the result of an Extension method, then you can use SetupReturnsDefault<ReturnTypeOfExtensionMethod>(new ConcreteInstanceToReturn()) on the instance of the mock class that has the extension method you are trying to mock.

It is not perfect, but for unit testing purposes it works well.

After hours of research this solution worked for me:

(disclaimer: results may vary due to circumstances)

the Library not found -lPods-(someCocoapod) error was due to multiple entries in the :

Settings(Target) > Build Settings > Linking > 'Other Linker Flags'

A lot of other posts had me look there and I would see changes to the error when I messed around with the entries, but I kept getting some variation on the same error.

Too many hours lost ...

My Fix:

remove the -lPods-(someCocoaPod) lines in the 'Other Linker Flags' list BUT only if $(inherited) is at the top. At first I was unsure, but the reassuring sign was that I still saw references to my cocoapods when I left the edit mode(inherited). I tested in debug and release, both of which were giving me errors, and the problem was immediately resolved.

If you want to use this lib then in ImageUploader.php you should move BulletProofException definition after namespace declaration. Submit pull-request for this issue to lib repo :)

EDIT: Make some changes in head of file:

namespace {
    class BulletProofException extends Exception{}
}

namespace BulletProof {

    class ImageUploader
    { ... }
}

var x = '<p>blah</p><div><a href="http://bs.serving-sys.com/BurstingPipe/adServer.bs?cn=brd&FlightID=2997227&Page=&PluID=0&Pos=9088" target="_blank"><img src="http://bs.serving-sys.com/BurstingPipe/adServer.bs?cn=bsr&FlightID=2997227&Page=&PluID=0&Pos=9088" border=0 width=300 height=250></a></div>';
$(x).children('div').html();

you can use WMI in .net too but you're then dependent on the wmi service running etc. Sometimes it works locally, but then fail when the same code is run on servers. I believe that's a namespace issue, related to the "names" whose values you're reading.

Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.

It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.

Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart and touchmove handlers, which may prevent the scroll entirely by calling preventDefault() on the event.

Solution: {passive: true}

By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user.

document.addEventListener("touchstart", function(e) {
    console.log(e.defaultPrevented);  // will be false
    e.preventDefault();   // does nothing since the listener is passive
    console.log(e.defaultPrevented);  // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);

DOM Spec , Demo Video , Explainer Doc

This is similar to @rafael-almeida 's answer, but I want to point out that as of requests 2.11+, there are not 3 values that verify can take, there are actually 4:

• True: validates against requests's internal trusted CAs.
• False: bypasses certificate validation completely. (Not recommended)
• Path to a CA_BUNDLE file. requests will use this to validate the server's certificates.
• Path to a directory containing public certificate files. requests will use this to validate the server's certificates.

The rest of my answer is about #4, how to use a directory containing certificates to validate:

Obtain the public certificates needed and place them in a directory.

Strictly speaking, you probably "should" use an out-of-band method of obtaining the certificates, but you could also just download them using any browser.

If the server uses a certificate chain, be sure to obtain every single certificate in the chain.

According to the requests documentation, the directory containing the certificates must first be processed with the "rehash" utility (openssl rehash).

(This requires openssl 1.1.1+, and not all Windows openssl implementations support rehash. If openssl rehash won't work for you, you could try running the rehash ruby script at https://github.com/ruby/openssl/blob/master/sample/c_rehash.rb , though I haven't tried this. )

I had some trouble with getting requests to recognize my certificates, but after I used the openssl x509 -outform PEM command to convert the certs to Base64 .pem format, everything worked perfectly.

You can also just do lazy rehashing:

try:
    # As long as the certificates in the certs directory are in the OS's certificate store, `verify=True` is fine.
    return requests.get(url, auth=auth, verify=True)
except requests.exceptions.SSLError:
    subprocess.run(f"openssl rehash -compat -v my_certs_dir", shell=True, check=True)
    return requests.get(url, auth=auth, verify="my_certs_dir")

The easy way is to annotate your getters and setters.

Here is the original example modified to exclude the plain text password, but then annotate a new method that just returns the password field as encrypted text.

class User {

    private String password;

    public void setPassword(String password) {
        this.password = password;
    }

    @JsonIgnore
    public String getPassword() {
        return password;
    }

    @JsonProperty("password")
    public String getEncryptedPassword() {
        // encryption logic
    }
}

I had the same requirements as you but couldn't find a suitable database. nStore was promising but the API was not nearly complete enough and not very coherent.

That's why I made NeDB, which a dependency-less embedded database for Node.js projects. You can use it with a simple require(), it is persistent, and its API is the most commonly used subset of the very well-known MongoDB API.

You can insert object items to an array as this

let obj = {_x000D_
  '1st': {_x000D_
    name: 'stackoverflow'_x000D_
  },_x000D_
  '2nd': {_x000D_
    name: 'stackexchange'_x000D_
  }_x000D_
};_x000D_
 _x000D_
 let wholeArray = Object.keys(obj).map(key => obj[key]);_x000D_
 _x000D_
 console.log(wholeArray);

ssize_t is used for functions whose return value could either be a valid size, or a negative value to indicate an error. It is guaranteed to be able to store values at least in the range [-1, SSIZE_MAX] (SSIZE_MAX is system-dependent).

So you should use size_t whenever you mean to return a size in bytes, and ssize_t whenever you would return either a size in bytes or a (negative) error value.

See: http://pubs.opengroup.org/onlinepubs/007908775/xsh/systypes.h.html

I needed this for SQL Server. Here it is:

UPDATE user_account 
SET student_education_facility_id = cnt.education_facility_id
from  (
   SELECT user_account_id,education_facility_id
   FROM user_account 
   WHERE user_type = 'ROLE_TEACHER'
) as cnt
WHERE user_account.user_type = 'ROLE_STUDENT' and cnt.user_account_id = user_account.teacher_id

I think it works with other RDBMSes (please confirm). I like the syntax because it's extensible.

The format I needed was this actually:

UPDATE table1 
SET f1 = cnt.computed_column
from  (
   SELECT id,computed_column --can be any complex subquery
   FROM table1
) as cnt
WHERE cnt.id = table1.id

Supposing div is #div and button is #button:

#div {
    display: table-cell;
    width: 100%;
    height: 100%;
    text-align: center;
    vertical-align: center;
}

#button {}

Then nest the button into div as usual.

pgcrypto Extension

As of Postgres 9.4, the pgcrypto module includes the gen_random_uuid() function. This function generates one of the random-number based Version 4 type of UUID.

Get contrib modules, if not already available.

sudo apt-get install postgresql-contrib-9.4

Use pgcrypto module.

CREATE EXTENSION "pgcrypto";

The gen_random_uuid() function should now available;

Example usage.

INSERT INTO items VALUES( gen_random_uuid(), 54.321, 31, 'desc 1', 31.94 ) ;

Quote from Postgres doc on uuid-ossp module.

Note: If you only need randomly-generated (version 4) UUIDs, consider using the gen_random_uuid() function from the pgcrypto module instead.

document.getElementById("someFormId").elements;

This collection will also contain <select>, <textarea> and <button> elements (among others), but you probably want that.

here is simple JQuery to do this to make div draggable with in only container :

$("#containerdiv div").draggable( {containment: "#containerdiv ", scroll: false} );

Alpine docker image doesn't have bash installed by default. You will need to add following commands to get bash:

RUN apk update && apk add bash

If youre using Alpine 3.3+ then you can just do

RUN apk add --no-cache bash

to keep docker image size small. (Thanks to comment from @sprkysnrky)

This is an old question but I've just encountered had a similar problem and the solution may help others:

Had the same issue where writing out CSV text data to a file, then opening the resulting .csv in Excel shifts all the text into a single column. After having a read of the above answers I tried the following, which seems to sort the problem out.

Apply an encoding of UTF-8 when you create your StreamWriter. That's it.

Example:

using (StreamWriter output = new StreamWriter(outputFileName, false, Encoding.UTF8, 2 << 22)) {
   /* ... do stuff .... */
   output.Close();
}

Use subquery

SELECT * FROM RES_DATA inner join (SELECT [CUSTOMER ID], sum([TOTAL AMOUNT]) FROM INV_DATA group by [CUSTOMER ID]) T on RES_DATA.[CUSTOMER ID] = t.[CUSTOMER ID]

The following answer is probably the most efficient but has the caveat of only being suitable for 1 to 1 mappings of arguments. This uses the fastest way of concatenating strings (similar to a stringbuilder: array of strings, joined). This is my own code. Probably needs a better separator though.

String.format = function(str, args)
{
    var t = str.split('~');
    var sb = [t[0]];
    for(var i = 0; i < args.length; i++){
        sb.push(args[i]);
        sb.push(t[i+1]);
    }
    return sb.join("");
}

Use it like:

alert(String.format("<a href='~'>~</a>", ["one", "two"]));

This clearly is a bad case of controller logic in a view. It would be better to do this in a controller and return the desired view.

[ChildActionOnly]
public ActionResult Results() 
{
    EnumerableRowCollection<DataRow> custs = ViewBag.Customers;
    bool anyRows = custs.Any();

    if(anyRows == false)
    {
        return View("NoResults");
    }
    else
    {
        return View("OtherView");
    }
}

Modify NoResults.cshtml to a Partial.

And call this as a Partial view in the parent view

@Html.Partial("Results")

You might have to pass the Customer collection as a model to the Result action or in a ViewDataDictionary due to reasons explained here: Can't access ViewBag in a partial view in ASP.NET MVC3

The ChildActionOnly attribute will make sure you cannot go to this page by navigating and that this view must be rendered as a partial, thus by a parent view. cfr: Using ChildActionOnly in MVC

To set it programmatically in Activity.java:

public void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setTheme(R.style.MyTheme); // (for Custom theme)
  setTheme(android.R.style.Theme_Holo); // (for Android Built In Theme)

  this.setContentView(R.layout.myactivity);

To set in Application scope in Manifest.xml (all activities):

 <application
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To set in Activity scope in Manifest.xml (single activity):

  <activity
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To build a custom theme, you will have to declare theme in themes.xml file, and set styles in styles.xml file.

You can use slice notation with steps:

>>> x = "abcdefghijklm"
>>> x[0::2] #0. 2. 4...
'acegikm'
>>> x[1::2] #1. 3. 5 ..
'bdfhjl'
>>> [i+j for i,j in zip(x[::2], x[1::2])] # zip makes (0,1),(2,3) ...
['ab', 'cd', 'ef', 'gh', 'ij', 'kl']

Same logic applies for lists too. String lenght doesn't matter, because you're simply adding two strings together.

When you have specified a width on the object that you have applied margin: 0 auto to, the object will sit centrally within it's parent container.

Specifying auto as the second parameter basically tells the browser to automatically determine the left and right margins itself, which it does by setting them equally. It guarantees that the left and right margins will be set to the same size. The first parameter 0 indicates that the top and bottom margins will both be set to 0.

margin-top:0;
margin-bottom:0;
margin-left:auto;
margin-right:auto;

Therefore, to give you an example, if the parent is 100px and the child is 50px, then the auto property will determine that there's 50px of free space to share between margin-left and margin-right:

var freeSpace = 100 - 50;
var equalShare = freeSpace / 2;

Which would give:

margin-left:25;
margin-right:25;

Have a look at this jsFiddle. You do not have to specify the parent width, only the width of the child object.

Working solution for SQL Server 2014. I have included only a handful of output fields here but feel free to add in as many as you like.

        c.object_id = o.object_id

        i.object_id = o.object_id

If you want to extract from a tag then

$('.dep_buttons').text().substr(0,25)

With the mouseover event,

$(this).text($(this).text().substr(0, 25));

The above will extract the text of a tag, then extract again assign it back.

I know that this is not a technical solution but I had my iphone connected with the computer by cable and disconnecting the device from the computer and connecting it again (by cable again) worked for me as I could not solved it with the solutions that are provided before.

Create Handler outside the Thread

final Handler handler = new Handler();

        new Thread(new Runnable() {
            @Override
            public void run() {
            try{
                 handler.post(new Runnable() {
                        @Override
                        public void run() {
                            showAlertDialog(p.getProviderName(), Token, p.getProviderId(), Amount);
                        }
                    });

                }
            }
            catch (Exception e){
                Log.d("ProvidersNullExp", e.getMessage());
            }
        }
    }).start();

use this:

pil_image = PIL.Image.open('Image.jpg').convert('RGB') 
open_cv_image = numpy.array(pil_image) 
# Convert RGB to BGR 
open_cv_image = open_cv_image[:, :, ::-1].copy() 

If you have another variable also referring to the same dictionary, there is a big difference:

>>> d = {"stuff": "things"}
>>> d2 = d
>>> d = {}
>>> d2
{'stuff': 'things'}
>>> d = {"stuff": "things"}
>>> d2 = d
>>> d.clear()
>>> d2
{}

This is because assigning d = {} creates a new, empty dictionary and assigns it to the d variable. This leaves d2 pointing at the old dictionary with items still in it. However, d.clear() clears the same dictionary that d and d2 both point at.

You can use URL Encoding Functions PHP has the

rawurlencode() 

function

ASP has the

Server.URLEncode() 

function

In JavaScript you can use the

encodeURIComponent() 

function.

You can use by functions as by(df1$Year, df1$Month, count) that will produce a list of needed aggregation.

The output will look like,

df1$Month: Feb
     x freq
1 2012    1
2 2013    1
3 2014    5
--------------------------------------------------------------- 
df1$Month: Jan
     x freq
1 2012    5
2 2013    2
--------------------------------------------------------------- 
df1$Month: Mar
     x freq
1 2012    1
2 2013    3
3 2014    2

Yes, assuming the account has appropriate permissions you can use:

SELECT <...>
FROM A.table1 t1 JOIN B.table2 t2 ON t2.column2 = t1.column1;

You just need to prefix the table reference with the name of the database it resides in.

This will give you the difference between two dates, in milliseconds

var diff = Math.abs(date1 - date2);

In your example, it'd be

var diff = Math.abs(new Date() - compareDate);

You need to make sure that compareDate is a valid Date object.

Something like this will probably work for you

var diff = Math.abs(new Date() - new Date(dateStr.replace(/-/g,'/')));

i.e. turning "2011-02-07 15:13:06" into new Date('2011/02/07 15:13:06'), which is a format the Date constructor can comprehend.

The dig utility is pretty convenient to use. The order of the arguments don't really matter.I'll show you some easy examples.
To get all root name servers use

# dig

To get a TXT record of a specific host use

# dig example.com txt
# dig host.example.com txt

The SPF RFC4408 says that SPF records can be stored as SPF or TXT. However nearly all use only TXT records at the moment. So you are pretty safe if you only fetch TXT records.

I made a SPF checker for visualising the SPF records of a domain. It might help you to understand SPF records better. You can find it here: http://spf.myisp.ch

You should use dynamic object to resolve combobox item in run-time.

comboBox.DisplayMember = "Text";
comboBox.ValueMember = "Value";

comboBox.Items.Add(new { Text = "Text", Value = "Value" });

(comboBox.SelectedItem as dynamic).Value

For the most common purpose, you should use bindValue.

bindParam has two tricky or unexpected behaviors:

• bindParam(':foo', 4, PDO::PARAM_INT) does not work, as it requires passing a variable (as reference).
• bindParam(':foo', $value, PDO::PARAM_INT) will change $value to string after running execute(). This, of course, can lead to subtle bugs that might be difficult to catch.

The caller-saved / callee-saved terminology is based on a pretty braindead inefficient model of programming where callers actually do save/restore all the call-clobbered registers (instead of keeping long-term-useful values elsewhere), and callees actually do save/restore all the call-preserved registers (instead of just not using some or any of them).

Or you have to understand that "caller-saved" means "saved somehow if you want the value later".

In reality, efficient code lets values get destroyed when they're no longer needed. Compilers typically make functions that save a few call-preserved registers at the start of a function (and restore them at the end). Inside the function, they use those regs for values that need to survive across function calls.

I prefer "call-preserved" vs. "call-clobbered", which are unambiguous and self-describing once you've heard of the basic concept, and don't require any serious mental gymnastics to think about from the caller's perspective or the callee's perspective. (Both terms are from the same perspective).

Plus, these terms differ by more than one letter.

The terms volatile / non-volatile are pretty good, by analogy with storage which loses its value on power-loss or not, (like DRAM vs. Flash). But the C volatile keyword has a totally different technical meaning, so that's a downside to "(non)-volatile" when describing C calling conventions.

• Call-clobbered, aka caller-saved or volatile registers are good for scratch / temporary values that aren't needed after the next function call.

From the callee's perspective, your function can freely overwrite (aka clobber) these registers without saving/restoring.

From a caller's perspective, call foo destroys (aka clobbers) all the call-clobbered registers, or at least you have to assume it does.

You can write private helper functions that have a custom calling convention, e.g. you know they don't modify a certain register. But if all you know (or want to assume or depend on) is that the target function follows the normal calling convention, then you have to treat a function call as if it does destroy all the call-clobbered registers. That's literally what the name come from: a call clobbers those registers.

Some compilers that do inter-procedural optimization can also create internal-use-only definitions of functions that don't follow the ABI, using a custom calling convention.

• Call-preserved, aka callee-saved or non-volatile registers keep their values across function calls. This is useful for loop variables in a loop that makes function calls, or basically anything in a non-leaf function in general.

From a callee's perspective, these registers can't be modified unless you save the original value somewhere so you can restore it before returning. Or for registers like the stack pointer (which is almost always call-preserved), you can subtract a known offset and add it back again before returning, instead of actually saving the old value anywhere. i.e. you can restore it by dead reckoning, unless you allocate a runtime-variable amount of stack space. Then typically you restore the stack pointer from another register.

A function that can benefit from using a lot of registers can save/restore some call-preserved registers just so it can use them as more temporaries, even if it doesn't make any function calls. Normally you'd only do this after running out of call-clobbered registers to use, because save/restore typically costs a push/pop at the start/end of the function. (Or if your function has multiple exit paths, a pop in each of them.)

The name "caller-saved" is misleading: you don't have to specially save/restore them. Normally you arrange your code to have values that need to survive a function call in call-preserved registers, or somewhere on the stack, or somewhere else that you can reload from. It's normal to let a call destroy temporary values.

An ABI or calling convention defines which are which

See for example What registers are preserved through a linux x86-64 function call for the x86-64 System V ABI.

Also, arg-passing registers are always call-clobbered in all function-calling conventions I'm aware of. See Are rdi and rsi caller saved or callee saved registers?

But system-call calling conventions typically make all the registers except the return value call-preserved. (Usually including even condition-codes / flags.) See What are the calling conventions for UNIX & Linux system calls on i386 and x86-64

You can give it a property display block; so it will behave like a div and have its own line

CSS:

.feature_desc {
   display: block;
   ....
}

If String.Compare(string1,string2,True) Then

    'perform operation

EndIf

Both are supported. To quote the Arduino homepage,

The core libraries are written in C and C++ and compiled using avr-gcc

Note that C++ is a superset of C (well, almost), and thus can often look very similar. I am not an expert, but I guess that most of what you will program for the Arduino in your first year on that platform will not need anything but plain C.

The two have different semantics when it comes to the key already existing in the map. So they aren't really directly comparable.

But the operator[] version requires default constructing the value, and then assigning, so if this is more expensive then copy construction, then it will be more expensive. Sometimes default construction doesn't make sense, and then it would be impossible to use the operator[] version.

I needed to create a drag and drop + rotation that works on desktop, mobile, tablet including windows phone. The last one made it more complicated (mspointer vs. touch events).

The solution came from The great Greensock library

It took some jumping through hoops to make the same object draggable and rotatable but it works perfectly

-- TRY THIS --

select name= case when isnumeric(empname)= 1 then 'numeric' else 'notmumeric' end from [Employees]

But conversion is quit impossible

select empname=
case
when isnumeric(empname)= 1 then empname
else 'notmumeric'
end
from [Employees]
