Programs & Examples On #Nntp

Not an answer, but perhpas of interest. I did send a proposal to the CSS WG a few years ago. However, nothing has happened. If indeed they (and browser vendors) would see this as a genuine developer concern, perhaps the ball could start rolling?

After checking catalina.sh (for windows use the .bat versions of everything mentioned below)

#   Do not set the variables in this script. Instead put them into a script
#   setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

Also this

#   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
#                   "run" or "debug" command is executed.
#                   Include here and not in JAVA_OPTS all options, that should
#                   only be used by Tomcat itself, not by the stop process,
#                   the version command etc.
#                   Examples are heap size, GC logging, JMX ports etc

So create a setenv.sh under CATALINA_BASE/bin (same dir where the catalina.sh resides). Edit the file and set the arguments to CATALINA_OPTS

For e.g. the file would look like this if you wanted to change the heap size

CATALINA_OPTS=-Xmx512m

Or in your case since you're using windows setenv.bat would be

set CATALINA_OPTS=-agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5

To clear the added options later just delete setenv.bat/sh

You can use .present? which comes included with ActiveSupport.

@city = @user.city.present?
# etc ...

You could even write it like this

def show
  %w(city state bio contact twitter mail).each do |attr|
    instance_variable_set "@#{attr}", @user[attr].present?
  end
end

It's worth noting that if you want to test if something is blank, you can use .blank? (this is the opposite of .present?)

Also, don't use foo == nil. Use foo.nil? instead.

You have the name of the apk and not the package name: You should first know the package name. Fot this tape:

adb shel pm list packages

Once you have the package name (be carefull, package name is like com.intel.... and not package:com.intel...), tape:

adb shell pm uninstall -k "package_name"

and Bingo!

If I understand correctly, you want this fiddle.

You can use String formatting for the double type. Here is an example:

double val = 58.6547;
String.Format("{0:0.##}", val);      
//Output: "58.65"

double val = 58.6;
String.Format("{0:0.##}", val);      
//Output: "58.6"

double val = 58.0;
String.Format("{0:0.##}", val);      
//Output: "58"

Let me know if this doesn't help.

Use

RefreshForm.submit(); 

instead of

document.location.reload(true); 

put id attribute on anchor element

<a id="link2">

set href attribute on page load event:

(function() {
    var scrt_var = 10;
    var strLink = "2.html&Key=" + scrt_var;
    document.getElementById("link2").setAttribute("href",strLink);
})();

I found very nice solution. Microsoft released a beta version of Entity Framework Power Tools: Entity Framework Power Tools Beta 2

There you can generate POCO classes, derived DbContext and Code First mapping for an existing database in some clicks. It is very nice!

After installation some context menu options would be added to your Visual Studio.

Right-click on a C# project. Choose Entity Framework-> Reverse Engineer Code First (Generates POCO classes, derived DbContext and Code First mapping for an existing database):

Then choose your database and click OK. That's all! It is very easy.

A simple explanation of the difference between json and jsonb (original image by PostgresProfessional):

SELECT '{"c":0,   "a":2,"a":1}'::json, '{"c":0,   "a":2,"a":1}'::jsonb;

          json          |        jsonb 
------------------------+--------------------- 
 {"c":0,   "a":2,"a":1} | {"a": 1, "c": 0} 
(1 row)

• json: textual storage «as is»
• jsonb: no whitespaces
• jsonb: no duplicate keys, last key win
• jsonb: keys are sorted

More in speech video and slide show presentation by jsonb developers. Also they introduced JsQuery, pg.extension provides powerful jsonb query language

Object to Array

Of all the answers I think this one is the best:

let arr = Object.entries(obj).map(([key, val]) => ({ key, ...val }))

that transforms:

{
  a: { p: 1, q: 2},
  b: { p: 3, q: 4}
}

to:

[
  { key: 'a', p: 1, q: 2 }, 
  { key: 'b', p: 3, q: 4 }
]

Array to Object

To transform back:

let obj = arr.reduce((obj, { key, ...val }) => { obj[key] = { ...val }; return obj; }, {})

To transform back keeping the key in the value:

let obj = arr.reduce((obj, { key, ...val }) => { obj[key] = { key, ...val }; return obj; }, {})

Will give:

{
  a: { key: 'a', p: 1, q: 2 },
  b: { key: 'b', p: 3, q: 4 }
}

For the last example you can also use lodash _.keyBy(arr, 'key') or _.keyBy(arr, i => i.key).

Im using jQuery Lazy. It took me about 10 minutes to test out and an hour or two to add to most of the image links on one of my websites (CollegeCarePackages.com). I have NO (none/zero) relationship of any kind to the dev, but it saved me a lot of time and basically helped improve our bounce rate for mobile users and I appreciate it.

You have to do:

git branch <branch_name> <commit>

(you were interchanging the branch name and commit)

Or you can do:

git checkout -b <branch_name> <commit>

If in place of you use branch name, you get a branch out of tip of the branch.

If your working directory points to the trunk, then you should be able to merge your branch with:

svn merge https://HOST/repository/branches/branch_1

be sure to be to issue this command in the root directory of your trunk

The following code should work :)

Having unsigned in variable declaration is more useful for the programmers themselves - don't treat the variables as negative. As you've noticed, both -1 and 4294967295 have exact same bit representation for a 4 byte integer. It's all about how you want to treat or see them.

The statement unsigned int a = -1; is converting -1 in two's complement and assigning the bit representation in a. The printf() specifier x, d and u are showing how the bit representation stored in variable a looks like in different format.

Maven is a build tool. Along with Ant or Gradle are Javas tools for building.
If you are a newbie in Java though just build using your IDE since Maven has a steep learning curve.

flutter config --android-sdk F:\SDK

Threads > switch "Main" to "app"

In the "Threads" section I changed the context from "Main" > to "app". The "app" should have a blue arrow aside.

You just can put your query as a subquery:

SELECT avg(count)
  FROM 
    (
    SELECT COUNT (*) AS Count
      FROM Table T
     WHERE T.Update_time =
               (SELECT MAX (B.Update_time )
                  FROM Table B
                 WHERE (B.Id = T.Id))
    GROUP BY T.Grouping
    ) as counts

Edit: I think this should be the same:

SELECT count(*) / count(distinct T.Grouping)
  FROM Table T
 WHERE T.Update_time =
           (SELECT MAX (B.Update_time)
              FROM Table B
             WHERE (B.Id = T.Id))

I just had a similar problem. The error said the same the in the question, tried to solve it with the answer of pkozlowski.opensource and Ben G, which both are correct and good answers.

My problem was indeed different with the same error:

in my HTML-Code I had the initialisation like this...

<html ng-app>

A bit further down I tried to do something like this:

<div id="cartView" ng-app="myApp" ng-controller="CartCtrl">

I got rid of the first one... then it worked... obviously you can't initialise ng-app twice or more times. fair enough.

I totaly forgot about the first "ng-app" and got totaly frustrated. Maybe this is gonna help someone oneday...

Here is exp.

$date_search_strtotime = strtotime(date("Y-m-d"));
echo 'Now strtotime date : '.$date_search_strtotime;
echo '<br>';
echo 'Now date from strtotime : '.date('Y-m-d',$date_search_strtotime);

If you don't see the formatting option, you can do Tools->Import and Export settings to import the missing one.

Use This:-

compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'

One thing that you could do would be to modify the catalina.sh (Unix based) or the catalina.bat (windows based).

Within each of the scripts you can set certain variables which only processes created under the shell will inherit. So for catalina.sh, use the following line:

export JAVA_HOME="intented java home"

And for windows use

set JAVA_HOME="intented java home"

You don't need jquery in order to do that.

var placeHolder="name";
var res=name.substr(name.indexOf(placeHolder) + placeHolder.length);

If none of the solutions above worked, try this 10-second fix.

Navigate to the startup project in solution explorer. Right click, properties > Application > Target framework. Change the target framework to anything else. Press Yes for the confirmation dialog. Give the changes a few seconds to take effect, then switch the framework back to what it was before.

The error will hopefully go away for you like it did for me!

(Note: root, base, apex domains are all the same thing. Using interchangeably for google-foo.)

Traditionally, to point your apex domain you'd use an A record pointing to your server's IP. This solution doesn't scale and isn't viable for a cloud platform like Heroku, where multiple and frequently changing backends are responsible for responding to requests.

For subdomains (like www.example.com) you can use CNAME records pointing to your-app-name.herokuapp.com. From there on, Heroku manages the dynamic A records behind your-app-name.herokuapp.com so that they're always up-to-date. Unfortunately, the DNS specification does not allow CNAME records on the zone apex (the base domain). (For example, MX records would break as the CNAME would be followed to its target first.)

Back to root domains, the simple and generic solution is to not use them at all. As a fallback measure, some DNS providers offer to setup an HTTP redirect for you. In that case, set it up so that example.com is an HTTP redirect to www.example.com.

Some DNS providers have come forward with custom solutions that allow CNAME-like behavior on the zone apex. To my knowledge, we have DNSimple's ALIAS record and DNS Made Easy's ANAME record; both behave similarly.

Using those, you could setup your records as (using zonefile notation, even tho you'll probably do this on their web user interface):

@   IN ALIAS your-app-name.herokuapp.com.
www IN CNAME your-app-name.herokuapp.com.

Remember @ here is a shorthand for the root domain (example.com). Also mind you that the trailing dots are important, both in zonefiles, and some web user interfaces.

See also:

• Doing DNS right with Heroku
• Avoiding Naked Domains and DNS A-records

Remarks:

• Amazon's Route 53 also has an ALIAS record type, but it's somewhat limited, in that it only works to point within AWS. At the moment I would not recommend using this for a Heroku setup.

• Some people confuse DNS providers with domain name registrars, as there's a bit of overlap with companies offering both. Mind you that to switch your DNS over to one of the aforementioned providers, you only need to update your nameserver records with your current domain registrar. You do not need to transfer your domain registration.

yes we can do this using nth-child like so

div:nth-child(n + 8) {
    background: red;
}

This will make the 8th div child onwards become red. Hope this helps...

Also, if someone ever says "hey, they can't be done with styled using css, use JS!!!" doubt them immediately. CSS is extremely flexible nowadays

Example :: http://jsfiddle.net/uWrLE/1/

In the example the first 7 children are blue, then 8 onwards are red...

Open your Android SDK Manager and ensure that you download/install a system image for the API level you are developing with.

Check out native HTML5 form validation:

http://www.the-art-of-web.com/html/html5-form-validation/

You can reverse the logic. Instead of deleting an invalid row after it has been inserted, write an INSTEAD OF trigger to insert only if you verify the row is valid.

CREATE TRIGGER mytrigger ON sometable
INSTEAD OF INSERT
AS BEGIN
  DECLARE @isnum TINYINT;

  SELECT @isnum = ISNUMERIC(somefield) FROM inserted;

  IF (@isnum = 1)
    INSERT INTO sometable SELECT * FROM inserted;
  ELSE
    RAISERROR('somefield must be numeric', 16, 1)
      WITH SETERROR;
END

If your application doesn't want to handle errors (as Joel says is the case in his app), then don't RAISERROR. Just make the trigger silently not do an insert that isn't valid.

I ran this on SQL Server Express 2005 and it works. Note that INSTEAD OF triggers do not cause recursion if you insert into the same table for which the trigger is defined.

Note that if you want to scroll an element instead of the full window, elements don't have the scrollTo and scrollBy methods. You should:

var el = document.getElementById("myel"); // Or whatever method to get the element

// To set the scroll
el.scrollTop = 0;
el.scrollLeft = 0;

// To increment the scroll
el.scrollTop += 100;
el.scrollLeft += 100;

You can also mimic the window.scrollTo and window.scrollBy functions to all the existant HTML elements in the webpage on browsers that don't support it natively:

Object.defineProperty(HTMLElement.prototype, "scrollTo", {
    value: function(x, y) {
        el.scrollTop = y;
        el.scrollLeft = x;
    },
    enumerable: false
});

Object.defineProperty(HTMLElement.prototype, "scrollBy", {
    value: function(x, y) {
        el.scrollTop += y;
        el.scrollLeft += x;
    },
    enumerable: false
});

so you can do:

var el = document.getElementById("myel"); // Or whatever method to get the element, again

// To set the scroll
el.scrollTo(0, 0);

// To increment the scroll
el.scrollBy(100, 100);

NOTE: Object.defineProperty is encouraged, as directly adding properties to the prototype is a breaking bad habit (When you see it :-).

To have a more general solution, you can write a generic Wrapper class:

public static class Wrapper<T> {
    public T obj;
    public Wrapper(T obj) { this.obj = obj; }
}
...
Wrapper<Integer> w = new Wrapper<>(0);
this.forEach(s -> {
    s.setOrdinal(w.obj);
    w.obj++;
});

(this is a variant of the solution given by Almir Campos).

In the specific case this is not a good solution, as Integer is worse than int for your purpose, anyway this solution is more general I think.

If you want to have same ratio you should create a container and hide a part of the image.

.container{_x000D_
  width:100%;_x000D_
  height:60px;_x000D_
  overflow:hidden;_x000D_
}_x000D_
.img {_x000D_
  width:100%;_x000D_
}

<div class="container">_x000D_
  <img src="http://placehold.it/100x100" class="img" alt="Our Location" /> _x000D_
</div>_x000D_
_x000D_
   

As explained here, in the context of main both return and exit do the same thing

Q: Why do we need to return or exit?

A: To indicate execution status.

In your example even if you didnt have return or exit statements the code would run fine (Assuming everything else is syntactically,etc-ally correct. Also, if (and it should be) main returns int you need that return 0 at the end).

But, after execution you don't have a way to find out if your code worked as expected. You can use the return code of the program (In *nix environments , using $?) which gives you the code (as set by exit or return) . Since you set these codes yourself you understand at which point the code reached before terminating.

You can write return 123 where 123 indicates success in the post execution checks.

Usually, in *nix environments 0 is taken as success and non-zero codes as failures.

For those who have updated to the latest version of google-play-services_lib and/or have this error Google Play services out of date. Requires 3136100 but found 2012110 this newer version of com.google.android.gms.apk (Google Play Services 3.1.36) and com.android.vending.apk (Google Play Store 4.1.6) should work.

Test with this configuration on Android SDK Tools 22.0.1. Another configuration that targets pure Android, not the Google one, should work too.

• Device: Galaxy Nexus
• Target: Android 4.2.2 - API Level 17
• CPU/ABI: ARM (armeabi-v7a)
• Checked: Use Host GPU

...

1. Open the AVD

2. Execute this in the terminal / cmd

   adb -e install com.google.android.gms.apk
   adb -e install com.android.vending.apk
   

3. Restart the AVD

4. Have fun coding!!!

I found this way to be the easiest, cleanest and it works with the newest version of the software, which allow you to get all the bug fixes.

Ok, so I actually stumbled across the answer.

phpMyAdmin does offer a brief history. If you click on the 'sql' icon just underneath the 'phpMyAdmin' logo, it'll open a new window. In the new window, just click on the 'history' tab.

That will give you the last twenty or so SQL operations.

If you are using Eclipse, try the following:

• Right click on the ant build file, then choose "Properties".
• Click on the "Run/Debug Settings", then click on the launch configuration file. You should be able to edit it then.
• After you click "Edit", you should see a new window with a "Properties" tab which will show you a list of Ant build properties. There is a "java.home" property in the list. Make sure it refers to the correct path.

This might work for you:

height: PropTypes.oneOfType([PropTypes.string, PropTypes.number]),

Out-File defaults to unicode encoding which is why you are seeing the behavior you are. Use -Encoding Ascii to change this behavior. In your case

Out-File -Encoding Ascii -append textfile.txt. 

Add-Content uses Ascii and also appends by default.

"This is a test" | Add-Content textfile.txt.

As for the lack of newline: You did not send a newline so it will not write one to file.

use setAttribute() and removeAttribute()

function disbtn(e) { 
    if ( someCondition == true ) {
       document.getElementById('btn1').setAttribute("disabled","disabled");
    } else {
       document.getElementById('btn1').removeAttribute("disabled");
    }
}

SEE DEMO

It depends on the used compiler.

For example, Windows' definition can be WIN32 or _WIN32.

And Linux' definition can be UNIX or __unix__ or LINUX or __linux__.

Another way is to use the subplots function and pass the width ratio with gridspec_kw:

import numpy as np
import matplotlib.pyplot as plt 

# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# plot it
f, (a0, a1) = plt.subplots(1, 2, gridspec_kw={'width_ratios': [3, 1]})
a0.plot(x, y)
a1.plot(y, x)

f.tight_layout()
f.savefig('grid_figure.pdf')

If you are using Visual Studio 2017 and come across this question, you might consider AxoCover. It's a free VS extension that integrates OpenCover, but supports VS2017 (it also appears to be under active development. +1).

VS Extension page

https://github.com/axodox/AxoTools

You can also try this.

 $(document).ready(function () {
            var url = "@(Html.Raw(Url.Action("ActionName", "ControllerName")))";
            $("#PartialViewDivId").load(url);
        setInterval(function () {
            var url = "@(Html.Raw(Url.Action("ActionName", "ControllerName")))";
            $("#PartialViewDivId").load(url);
        }, 30000); //Refreshes every 30 seconds

        $.ajaxSetup({ cache: false });  //Turn off caching
    });

It makes an initial call to load the div, and then subsequent calls are on a 30 second interval.

In the controller section you can update the object and pass the object to the partial view.

public class ControllerName: Controller
{
    public ActionResult ActionName()
    {
        .
        .   // code for update object
        .
        return PartialView("PartialViewName", updatedObject);
    }
}

I checked some of the methods for speed performance and find that there is no difference! The only difference is that using some methods you must carefully check dimension.

Timing:

|------------|----------------|-------------------|
|            | shape (10000)  |  shape (1,10000)  |
|------------|----------------|-------------------|
| np.concat  |    0.18280     |      0.17960      |
|------------|----------------|-------------------|
|  np.stack  |    0.21501     |      0.16465      |
|------------|----------------|-------------------|
| np.vstack  |    0.21501     |      0.17181      |
|------------|----------------|-------------------|
|  np.array  |    0.21656     |      0.16833      |
|------------|----------------|-------------------|

As you can see I tried 2 experiments - using np.random.rand(10000) and np.random.rand(1, 10000) And if we use 2d arrays than np.stack and np.array create additional dimension - result.shape is (1,10000,10000) and (10000,1,10000) so they need additional actions to avoid this.

Code:

from time import perf_counter
from tqdm import tqdm_notebook
import numpy as np
l = []
for i in tqdm_notebook(range(10000)):
    new_np = np.random.rand(10000)
    l.append(new_np)



start = perf_counter()
stack = np.stack(l, axis=0 )
print(f'np.stack: {perf_counter() - start:.5f}')

start = perf_counter()
vstack = np.vstack(l)
print(f'np.vstack: {perf_counter() - start:.5f}')

start = perf_counter()
wrap = np.array(l)
print(f'np.array: {perf_counter() - start:.5f}')

start = perf_counter()
l = [el.reshape(1,-1) for el in l]
conc = np.concatenate(l, axis=0 )
print(f'np.concatenate: {perf_counter() - start:.5f}')

The definition of SIZE_T is found at: https://msdn.microsoft.com/en-us/library/cc441980.aspx and https://msdn.microsoft.com/en-us/library/cc230394.aspx

Pasting here the required information:

SIZE_T is a ULONG_PTR representing the maximum number of bytes to which a pointer can point.

This type is declared as follows:

typedef ULONG_PTR SIZE_T;

A ULONG_PTR is an unsigned long type used for pointer precision. It is used when casting a pointer to a long type to perform pointer arithmetic.

This type is declared as follows:

typedef unsigned __int3264 ULONG_PTR;

int dp1 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 1,
            context.getResources().getDisplayMetrics());

tv.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
dp1 * 100)); // if you want to set layout height to 100dp

llview.addView(tv);

Use this version of the assert statement to provide a detail message for the AssertionError. The system passes the value of Expression2 to the appropriate AssertionError constructor, which uses the string representation of the value as the error's detail message.

The purpose of the detail message is to capture and communicate the details of the assertion failure. The message should allow you to diagnose and ultimately fix the error that led the assertion to fail. Note that the detail message is not a user-level error message, so it is generally unnecessary to make these messages understandable in isolation, or to internationalize them. The detail message is meant to be interpreted in the context of a full stack trace, in conjunction with the source code containing the failed assertion.

Ruby automatically converts integers to a large integer class when they overflow, so there's (practically) no limit to how big they can be.

If you are looking for the machine's size, i.e. 64- or 32-bit, I found this trick at ruby-forum.com:

machine_bytes = ['foo'].pack('p').size
machine_bits = machine_bytes * 8
machine_max_signed = 2**(machine_bits-1) - 1
machine_max_unsigned = 2**machine_bits - 1

If you are looking for the size of Fixnum objects (integers small enough to store in a single machine word), you can call 0.size to get the number of bytes. I would guess it should be 4 on 32-bit builds, but I can't test that right now. Also, the largest Fixnum is apparently 2**30 - 1 (or 2**62 - 1), because one bit is used to mark it as an integer instead of an object reference.

mainJSON.getJSONArray("source") returns a JSONArray, hence you can remove the new JSONArray.

The JSONArray contructor with an object parameter expects it to be a Collection or Array (not JSONArray)

Try this:

JSONArray jsonMainArr = mainJSON.getJSONArray("source"); 

If you are using Eclipse you can move files to and from the SD Card through the Android Perspective (it is called DDMS in Eclipse). Just select the Emulator in the left part of the screen and then choose the File Explorer tab. Above the list with your files should be two symbols, one with an arrow pointing at a phone, clicking this will allow you to choose a file to move to phone memory.

This was not as straightforward as I would have hoped. You need to use enumerate to keep track of how many columns you have. Then use that counter to look up the name of the column. The accepted answer does not show you how to access the column names dynamically.

for row in df.itertuples(index=False, name=None):
    for k,v in enumerate(row):
        print("column: {0}".format(df.columns.values[k]))
        print("value: {0}".format(v)

Look here.

Basically you have to do bind params:

$sql = "SELECT username FROM users WHERE locationid IN (SELECT locationid FROM locations WHERE countryid=?)"; 

$this->db->query($sql, '__COUNTRY_NAME__');

But, like Mr.E said, use joins:

$sql = "select username from users inner join locations on users.locationid = locations.locationid where countryid = ?"; 

$this->db->query($sql, '__COUNTRY_NAME__');

Some functions, like INDEX'ing, can take a very long time - and it locks the whole database while it runs. In instances like that, it might not even use the journal file!

So the best/only way to check if your database is locked because a process is ACTIVELY writing to it (and thus you should leave it the hell alone until its completed its operation) is to md5 (or md5sum on some systems) the file twice. If you get a different checksum, the database is being written, and you really really REALLY don't want to kill -9 that process because you can easily end up with a corrupt table/database if you do.

I'll reiterate, because it's important - the solution is NOT to find the locking program and kill it - it's to find if the database has a write lock for a good reason, and go from there. Sometimes the correct solution is just a coffee break.

The only way to create this locked-but-not-being-written-to situation is if your program runs BEGIN EXCLUSIVE, because it wanted to do some table alterations or something, then for whatever reason never sends an END afterwards, and the process never terminates. All three conditions being met is highly unlikely in any properly-written code, and as such 99 times out of 100 when someone wants to kill -9 their locking process, the locking process is actually locking your database for a good reason. Programmers don't typically add the BEGIN EXCLUSIVE condition unless they really need to, because it prevents concurrency and increases user complaints. SQLite itself only adds it when it really needs to (like when indexing).

Finally, the 'locked' status does not exist INSIDE the file as several answers have stated - it resides in the Operating System's kernel. The process which ran BEGIN EXCLUSIVE has requested from the OS a lock be placed on the file. Even if your exclusive process has crashed, your OS will be able to figure out if it should maintain the file lock or not!! It is not possible to end up with a database which is locked but no process is actively locking it!! When it comes to seeing which process is locking the file, it's typically better to use lsof rather than fuser (this is a good demonstration of why: https://unix.stackexchange.com/questions/94316/fuser-vs-lsof-to-check-files-in-use). Alternatively if you have DTrace (OSX) you can use iosnoop on the file.

This is an answer to question 8391979, "Does java have a int.tryparse that doesn't throw an exception for bad data? [duplicate]" which is closed and linked to this question.

Edit 2016 08 17: Added ltrimZeroes methods and called them in tryParse(). Without leading zeroes in numberString may give false results (see comments in code). There is now also public static String ltrimZeroes(String numberString) method which works for positive and negative "numbers"(END Edit)

        IntBoxSimple ibs = IntBoxSimple.makeIntBoxSimple();
        String in = null;
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        do {
            System.out.printf(
                    "Enter an integer number in the range %d to %d:%n",
                        Integer.MIN_VALUE, Integer.MAX_VALUE);
            try { in = br.readLine(); } catch (IOException ex) {}
        } while(! IntBoxSimple.tryParse(in, ibs));
        System.out.printf("The number you have entered was: %d%n", ibs.v());
    }
}

This can be done with 3 lines of CSS and is compatible back to (and including) IE9:

.element {
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

Configure the maven-compiler-plugin to use the same character encoding that your source files are encoded in (e.g):

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
        <source>1.6</source>
        <target>1.6</target>
        <encoding>UTF-8</encoding>
    </configuration>
</plugin>

Many maven plugins will by default use the "project.build.sourceEncoding" property so setting this in your pom will cover most plugins.

<project>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>
...

However, I prefer setting the encoding in each plugin's configuration that supports it as I like to be explicit.

When your source code is compiled by the maven-compiler-plugin your source code files are read in by the compiler plugin using whatever encoding the compiler plugin is configured with. If your source files have a different encoding than the compiler plugin is using then it is possible that some characters may not exist in both encodings.

Many people prefer to set the encoding on their source files to UTF-8 so as to avoid this problem. To do this in Eclipse you can right click on a project and select Properties->Resource->Text File Encoding and change it to UTF-8. This will encode all your source files in UTF-8. (You should also explicitly configure the maven-compiler-plugin as mentioned above to use UTF-8 encoding.) With your source files and the compiler plugin both using the same encoding you shouldn't have any more unmappable characters during compilation.

Note, You can also set the file encoding globally in eclipse through Window->Preferences->General->Workspace->Text File Encoding. You can also set the encoding per file type through Window->Preferences->General->Content Types.

The most important reason of a String being made immutable in Java is Security consideration. Next would be Caching.

I believe other reasons given here, such as efficiency, concurrency, design and string pool follows from the fact that String in made immutable. For eg. String Pool could be created because String was immutable and not the other way around.

Check Gosling interview transcript here

From a strategic point of view, they tend to more often be trouble free. And there are usually things you can do with immutables that you can't do with mutable things, such as cache the result. If you pass a string to a file open method, or if you pass a string to a constructor for a label in a user interface, in some APIs (like in lots of the Windows APIs) you pass in an array of characters. The receiver of that object really has to copy it, because they don't know anything about the storage lifetime of it. And they don't know what's happening to the object, whether it is being changed under their feet.

You end up getting almost forced to replicate the object because you don't know whether or not you get to own it. And one of the nice things about immutable objects is that the answer is, "Yeah, of course you do." Because the question of ownership, who has the right to change it, doesn't exist.

One of the things that forced Strings to be immutable was security. You have a file open method. You pass a String to it. And then it's doing all kind of authentication checks before it gets around to doing the OS call. If you manage to do something that effectively mutated the String, after the security check and before the OS call, then boom, you're in. But Strings are immutable, so that kind of attack doesn't work. That precise example is what really demanded that Strings be immutable

You have to use Kendo UI DropDownList select method (documentation in here).

Basically you should:

// get a reference to the dropdown list
var dropdownlist = $("#Instrument").data("kendoDropDownList");

If you know the index you can use:

// selects by index
dropdownlist.select(1);

If not, use:

// selects item if its text is equal to "test" using predicate function
dropdownlist.select(function(dataItem) {
    return dataItem.symbol === "test";
});

JSFiddle example here

I recently discovered an interesting trick that allows to "Split String With String As Delimiter", so I couldn't resist the temptation to post it here as a new answer. Note that "obviously the question wasn't accurate. Firstly, both string1 and string2 can contain spaces. Secondly, both string1 and string2 can contain ampersands ('&')". This method correctly works with the new specifications (posted as a comment below Stephan's answer).

@echo off
setlocal

set "str=string1&with spaces by string2&with spaces.txt"

set "string1=%str: by =" & set "string2=%"
set "string2=%string2:.txt=%"

echo "%string1%"
echo "%string2%"

For further details on the split method, see this post.

Depending on which OS you're using, if you are flexible, then CHOICE can be used to wait on almost any key EXCEPT enter

If you are really referring to what Microsoft insists on calling "Command Prompt" which is simply an MS-DOS emulator, then perhaps TIMEOUT may suit your purpose (timeout /t -1 waits on any key, not just ENTER) and of course CHOICE is available again in recent WIN editions.

And a warning on SET /P - whereas set /p DUMMY=Hit ENTER to continue... will work,

set "dummy="
set /p DUMMY=Hit ENTER to continue...
if defined dummy (echo not just ENTER was pressed) else (echo just ENTER was pressed)

will detect whether just ENTER or something else, ending in ENTER was keyed in.

The HTTP 1.1 specification says:

URIs in HTTP can be represented in absolute form or relative to some
known base URI [11], depending upon the context of their use. The two
forms are differentiated by the fact that absolute URIs always begin
with a scheme name followed by a colon. For definitive information on
URL syntax and semantics, see "Uniform Resource Identifiers (URI): Generic Syntax and Semantics," RFC 2396 [42] (which replaces RFCs 1738 [4] and RFC 1808 [11]). This specification adopts the definitions of "URI-reference", "absoluteURI", "relativeURI", "port",
"host","abs_path", "rel_path", and "authority" from that
specification.

The HTTP protocol does not place any a priori limit on the length of
a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they provide GET-based forms that could generate such URIs.* A server SHOULD return 414 (Request-URI Too Long) status if a URI is longer than the server can handle (see section 10.4.15).

Note: Servers ought to be cautious about depending on URI lengths above 255 bytes, because some older client or proxy implementations might not properly support these lengths.

As mentioned by @Brian, the HTTP clients (e.g. browsers) may have their own limits, and HTTP servers will have different limits.

I also had this problem recently, and it was the SELinux which caused it. I was trying to have the post-commit of subversion to notify Jenkins that the code has change so Jenkins would do a build and deploy to Nexus.

I had to do the following to get it to work.

1) First I checked if SELinux is enabled:

    less /selinux/enforce

This will output 1 (for on) or 0 (for off)

2) Temporary disable SELinux:

    echo 0 > /selinux/enforce

Now test see if it works now.

3) Enable SELinux:

    echo 1 > /selinux/enforce

Change the policy for SELinux.

4) First view the current configuration:

    /usr/sbin/getsebool -a | grep httpd

This will give you: httpd_can_network_connect --> off

5) Set this to on and your post-commit will work with SELinux:

    /usr/sbin/setsebool -P httpd_can_network_connect on

Now it should be working again.

Simple function to accomplish this:

def insert_str(string, str_to_insert, index):
    return string[:index] + str_to_insert + string[index:]

I believe I have a much simpeler solution for this.

public class MyFragment extends Fragment{

   private String mTitle;
   private List<MyObject> mObjects;

   public static MyFragment newInstance(String title, List<MyObject> objects)
   MyFragment myFrag = new MyFragment();
   myFrag.mTitle = title;
   myFrag.mObjects = objects;
   return myFrag;
   }

This can be done elegantly with Ray, a system that allows you to easily parallelize and distribute your Python code.

To parallelize your example, you'd need to define your functions with the @ray.remote decorator, and then invoke them with .remote.

import ray

ray.init()

dir1 = 'C:\\folder1'
dir2 = 'C:\\folder2'
filename = 'test.txt'
addFiles = [25, 5, 15, 35, 45, 25, 5, 15, 35, 45]

# Define the functions. 
# You need to pass every global variable used by the function as an argument.
# This is needed because each remote function runs in a different process,
# and thus it does not have access to the global variables defined in 
# the current process.
@ray.remote
def func1(filename, addFiles, dir):
    # func1() code here...

@ray.remote
def func2(filename, addFiles, dir):
    # func2() code here...

# Start two tasks in the background and wait for them to finish.
ray.get([func1.remote(filename, addFiles, dir1), func2.remote(filename, addFiles, dir2)]) 

If you pass the same argument to both functions and the argument is large, a more efficient way to do this is using ray.put(). This avoids the large argument to be serialized twice and to create two memory copies of it:

largeData_id = ray.put(largeData)

ray.get([func1(largeData_id), func2(largeData_id)])

Important - If func1() and func2() return results, you need to rewrite the code as follows:

ret_id1 = func1.remote(filename, addFiles, dir1)
ret_id2 = func2.remote(filename, addFiles, dir2)
ret1, ret2 = ray.get([ret_id1, ret_id2])

There are a number of advantages of using Ray over the multiprocessing module. In particular, the same code will run on a single machine as well as on a cluster of machines. For more advantages of Ray see this related post.

Override all methods

    @Override
    public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {


    }

    @Override
    public void onStartTrackingTouch(SeekBar arg0) {


    }

    @Override
    public void onStopTrackingTouch(SeekBar arg0) {


    }

axios.delete does support a request body. It accepts two parameters: url and optional config. You can use config.data to set the request body and headers as follows:

axios.delete(url, { data: { foo: "bar" }, headers: { "Authorization": "***" } });

See here - https://github.com/axios/axios/issues/897

foreach($_POST as $key=>$value)
{

   if(empty(trim($value))
        echo "$key input required of value ";

}

In my case this error was caused by hot reloading, while introducing new classes. In that stage of the project, use normal watchers to compile your code.

You can also add hash when page is loading:

location.hash = "noBack";

Then just handle location hash change to add another hash:

$(window).on('hashchange', function() {
    location.hash = "noBack";
});

That makes hash always present and back button tries to remove hash at first. Hash is then added again by "hashchange" handler - so page would never actually can be changed to previous one.

Zip Arrays of same length:

Using Array.prototype.map()

const zip = (a, b) => a.map((k, i) => [k, b[i]]);

console.log(zip([1,2,3], ["a","b","c"]));
// [[1, "a"], [2, "b"], [3, "c"]]

Zip Arrays of different length:

Using Array.from()

const zip = (a, b) => Array.from(Array(Math.max(b.length, a.length)), (_, i) => [a[i], b[i]]);

console.log( zip([1,2,3], ["a","b","c","d"]) );
// [[1, "a"], [2, "b"], [3, "c"], [undefined, "d"]]

Using Array.prototype.fill() and Array.prototype.map()

const zip = (a, b) => Array(Math.max(b.length, a.length)).fill().map((_,i) => [a[i], b[i]]);

console.log(zip([1,2,3], ["a","b","c","d"]));
// [[1, "a"], [2, "b"], [3, "c"], [undefined, 'd']]

I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:

1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)

2: Run your formula

3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank

4: Replace All

Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.

UPDATE (Jan 2020): There are many great online places to get beginner practice at Python, some which are highly engaging and/or otherwise interactive. These sites are generally more practical than the Python Challenge (http://pythonchallenge.com), which you can tackle later. (After years of experience, you can try the Python "wat" quiz).

Even as it got the most votes, one usually can't take System.Collections.Concurrent.ConcurrentBag<T> as a thread-safe replacement for System.Collections.Generic.List<T> as it is (Radek Stromský already pointed it out) not ordered.

But there is a class called System.Collections.Generic.SynchronizedCollection<T> that is already since .NET 3.0 part of the framework, but it is that well hidden in a location where one does not expect it that it is little known and probably you have never ever stumbled over it (at least I never did).

SynchronizedCollection<T> is compiled into assembly System.ServiceModel.dll (which is part of the client profile but not of the portable class library).

If the response is in json then it would be like:

alert(response.id);

Otherwise

var str='{"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}';

For the allowed characters you can use

^[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$

to validate a complete string that should consist of only allowed characters. Note that - is at the end (because otherwise it'd be a range) and a few characters are escaped.

For the invalid characters you can use

[<>'"/;`%]

to check for them.

To combine both into a single regex you can use

^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])

but you'd need a regex engine that allows lookahead.

This will probably fix your problem if you're struggling to deploy a React solution that was created with the Visual Studio template (and has a web.config). In Azure Release Pipelines, when selecting the template, use:

Instead of:

It worked for me!

try this , it works 100 % : add columns and rows programatically : you need to create item class at first :

public class Item
        {
            public int Num { get; set; }
            public string Start { get; set; }
            public string Finich { get; set; }
        }

        private void generate_columns()
        {
            DataGridTextColumn c1 = new DataGridTextColumn();
            c1.Header = "Num";
            c1.Binding = new Binding("Num");
            c1.Width = 110;
            dataGrid1.Columns.Add(c1);
            DataGridTextColumn c2 = new DataGridTextColumn();
            c2.Header = "Start";
            c2.Width = 110;
            c2.Binding = new Binding("Start");
            dataGrid1.Columns.Add(c2);
            DataGridTextColumn c3 = new DataGridTextColumn();
            c3.Header = "Finich";
            c3.Width = 110;
            c3.Binding = new Binding("Finich");
            dataGrid1.Columns.Add(c3);

            dataGrid1.Items.Add(new Item() { Num = 1, Start = "2012, 8, 15", Finich = "2012, 9, 15" });
            dataGrid1.Items.Add(new Item() { Num = 2, Start = "2012, 12, 15", Finich = "2013, 2, 1" });
            dataGrid1.Items.Add(new Item() { Num = 3, Start = "2012, 8, 1", Finich = "2012, 11, 15" });

        }

Because Javascript changes very slowly. And that's because people upgrade browsers slowly.

Many Javascript libraries implement their own last() function. Use one!

In my apps I have a class which wraps the Log class which has a static boolean var called "state". Throughout my code I check the value of the "state" variable using a static method before actually writing to the Log. I then have a static method to set the "state" variable which ensures the value is common across all instances created by the app. This means I can enable or disable all logging for the App in one call - even when the App is running. Useful for support calls... It does mean that you have to stick to your guns when debugging and not regress to using the standard Log class though...

It's also useful (convenient) that Java interprets a boolean var as false if it hasn't been assigned a value, which means it can be left as false until you need to turn on logging :-)

Try this, with strings:

set "var=string1string2string3"

and with string variables:

set "var=%string1%%string2%%string3%"

Reset the diagnostics and the static analysis under the, for example, Properties -> FORTRAN -> diagnostics. Particular be careful the 'Level of Static Security Analysis' and set it none. Good luck!

Scikit-learn (which I recommend using anyways) has it included in the metrics module:

>>> from sklearn.metrics import confusion_matrix
>>> y_true = [0, 1, 2, 0, 1, 2, 0, 1, 2]
>>> y_pred = [0, 0, 0, 0, 1, 1, 0, 2, 2]
>>> confusion_matrix(y_true, y_pred)
array([[3, 0, 0],
       [1, 1, 1],
       [1, 1, 1]])

Based on @Peter Baley answer, I created a more generic function:

   @objectId: HTML object ID
   @values: can be a string or an array. String is less "secure" (should not contain repeated value).
   function checkMultiValues(objectId, values){
        selectMultiObject=document.getElementById(objectId);
        for ( var i = 0, l = selectMultiObject.options.length, o; i < l; i++ )
        {
          o = selectMultiObject.options[i];
          if ( values.indexOf( o.value ) != -1 )
          {
            o.selected = true;
          } else {
            o.selected = false;
          }
        }
    }

Example: checkMultiValues('thisMultiHTMLObject','a,b,c,d');

Propose a much more readable solution (in Python, but applies to any regex):

def url_path_to_dict(path):
    pattern = (r'^'
               r'((?P<schema>.+?)://)?'
               r'((?P<user>.+?)(:(?P<password>.*?))?@)?'
               r'(?P<host>.*?)'
               r'(:(?P<port>\d+?))?'
               r'(?P<path>/.*?)?'
               r'(?P<query>[?].*?)?'
               r'$'
               )
    regex = re.compile(pattern)
    m = regex.match(path)
    d = m.groupdict() if m is not None else None

    return d

def main():
    print url_path_to_dict('http://example.example.com/example/example/example.html')

Prints:

{
'host': 'example.example.com', 
'user': None, 
'path': '/example/example/example.html', 
'query': None, 
'password': None, 
'port': None, 
'schema': 'http'
}

High resolution timers that provide a resolution of 1 microsecond are system-specific, so you will have to use different methods to achieve this on different OS platforms. You may be interested in checking out the following article, which implements a cross-platform C++ timer class based on the functions described below:

• [Song Ho Ahn - High Resolution Timer][1]

Windows

The Windows API provides extremely high resolution timer functions: QueryPerformanceCounter(), which returns the current elapsed ticks, and QueryPerformanceFrequency(), which returns the number of ticks per second.

Example:

#include <stdio.h>
#include <windows.h>                // for Windows APIs

int main(void)
{
    LARGE_INTEGER frequency;        // ticks per second
    LARGE_INTEGER t1, t2;           // ticks
    double elapsedTime;

    // get ticks per second
    QueryPerformanceFrequency(&frequency);

    // start timer
    QueryPerformanceCounter(&t1);

    // do something
    // ...

    // stop timer
    QueryPerformanceCounter(&t2);

    // compute and print the elapsed time in millisec
    elapsedTime = (t2.QuadPart - t1.QuadPart) * 1000.0 / frequency.QuadPart;
    printf("%f ms.\n", elapsedTime);
}

Linux, Unix, and Mac

For Unix or Linux based system, you can use gettimeofday(). This function is declared in "sys/time.h".

Example:

#include <stdio.h>
#include <sys/time.h>                // for gettimeofday()

int main(void)
{
    struct timeval t1, t2;
    double elapsedTime;

    // start timer
    gettimeofday(&t1, NULL);

    // do something
    // ...

    // stop timer
    gettimeofday(&t2, NULL);

    // compute and print the elapsed time in millisec
    elapsedTime = (t2.tv_sec - t1.tv_sec) * 1000.0;      // sec to ms
    elapsedTime += (t2.tv_usec - t1.tv_usec) / 1000.0;   // us to ms
    printf("%f ms.\n", elapsedTime);
}

The ALTER TABLE statement presented by Chris should work, but first you need to declare the columns NOT NULL. All parts of a primary key need to be NOT NULL.

As of currently (September 2014) I would recommend using NSInteger/CGFloat when interacting with iOS API's etc if you are also building your app for arm64. This is because you will likely get unexpected results when you use the float, long and int types.

EXAMPLE: FLOAT/DOUBLE vs CGFLOAT

As an example we take the UITableView delegate method tableView:heightForRowAtIndexPath:.

In a 32-bit only application it will work fine if it is written like this:

-(float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 44;
}

float is a 32-bit value and the 44 you are returning is a 32-bit value. However, if we compile/run this same piece of code in a 64-bit arm64 architecture the 44 will be a 64-bit value. Returning a 64-bit value when a 32-bit value is expected will give an unexpected row height.

You can solve this issue by using the CGFloat type

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 44;
}

This type represents a 32-bit float in a 32-bit environment and a 64-bit double in a 64-bit environment. Therefore when using this type the method will always receive the expected type regardless of compile/runtime environment.

The same is true for methods that expect integers. Such methods will expect a 32-bit int value in a 32-bit environment and a 64-bit long in a 64-bit environment. You can solve this case by using the type NSInteger which serves as an int or a long based on the compile/runtime environemnt.

About AS:

• When used on result column, AS is optional.
• When used on table name, AS shouldn't be added, otherwise it's an error.

About double quote:

• It's optional & valid for both result column & table name.

e.g

-- 'AS' is optional for result column
select (1+1) as result from dual;
select (1+1) result from dual;


-- 'AS' shouldn't be used for table name
select 'hi' from dual d;


-- Adding double quotes for alias name is optional, but valid for both result column & table name,
select (1+1) as "result" from dual;
select (1+1) "result" from dual;

select 'hi' from dual "d";

I spent two days of my life tracking down some multi-threaded COM ref-counting issue because some idiot put this in a header file. I won't mention the company I worked for at the time.

The moral of this story? If you don't understand something, read the documentation and learn about it. Don't just make it go away.

If you are looking for an objective analysis of both the editors, look at their origins and the philosophy behind their respective designs. Think, which one would suit you better and learn it (and learn it and learn it, because it takes time before you being to discover its true utility as against any IDE). An Introduction to Display Editing with Vi was written by Bill Joy and Mark Horton and he explains why he choose modal design and rationale for various key strokes ( it helps me to remember that CTRL-W +W (will switch to next Window and it will same for CTRL W+ CTRL W, just in case you held the CTRL key for a longer duration.

Here is a link to Emacs timeline and has the reference to Multics Emacs paper. Hereis RMS paper on Emacs, where I see the stress is on a programmable text editor (even way back in 1981 and before).

I have not read the emacs papers, but have read Bill Joy's vi paper a couple of times. Both are old, but still you will get the philosophy and you might choose to use the current tool (vim 7.x or emacs 25?)

Edit: I forgot to mention that it takes patience and imagination to read both these papers as it takes you back in time while reading it. But it is worth.

Firebase Notifications doesn't have an API to send messages. Luckily it is built on top of Firebase Cloud Messaging, which has precisely such an API.

With Firebase Notifications and Cloud Messaging, you can send so-called downstream messages to devices in three ways:

1. to specific devices, if you know their device IDs
2. to groups of devices, if you know the registration IDs of the groups
3. to topics, which are just keys that devices can subscribe to

You'll note that there is no way to send to all devices explicitly. You can build such functionality with each of these though, for example: by subscribing the app to a topic when it starts (e.g. /topics/all) or by keeping a list of all device IDs, and then sending the message to all of those.

For sending to a topic you have a syntax error in your command. Topics are identified by starting with /topics/. Since you don't have that in your code, the server interprets allDevices as a device id. Since it is an invalid format for a device registration token, it raises an error.

From the documentation on sending messages to topics:

https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

{
  "to": "/topics/foo-bar",
  "data": {
    "message": "This is a Firebase Cloud Messaging Topic Message!",
   }
}

Python 3's range type works just like Python 2's xrange. I'm not sure why you're seeing a slowdown, since the iterator returned by your xrange function is exactly what you'd get if you iterated over range directly.

I'm not able to reproduce the slowdown on my system. Here's how I tested:

Python 2, with xrange:

Python 2.7.3 (default, Apr 10 2012, 23:24:47) [MSC v.1500 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import timeit
>>> timeit.timeit("[x for x in xrange(1000000) if x%4]",number=100)
18.631936646865853

Python 3, with range is a tiny bit faster:

Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:57:17) [MSC v.1600 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import timeit
>>> timeit.timeit("[x for x in range(1000000) if x%4]",number=100)
17.31399508687869

I recently learned that Python 3's range type has some other neat features, such as support for slicing: range(10,100,2)[5:25:5] is range(20, 60, 10)!

I change upload method with images[] according to @Denmark.

    private function upload_files($path, $title, $files)
    {
        $config = array(
            'upload_path'   => $path,
            'allowed_types' => 'jpg|gif|png',
            'overwrite'     => 1,                       
        );

        $this->load->library('upload', $config);

        $images = array();

        foreach ($files['name'] as $key => $image) {
            $_FILES['images[]']['name']= $files['name'][$key];
            $_FILES['images[]']['type']= $files['type'][$key];
            $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
            $_FILES['images[]']['error']= $files['error'][$key];
            $_FILES['images[]']['size']= $files['size'][$key];

            $fileName = $title .'_'. $image;

            $images[] = $fileName;

            $config['file_name'] = $fileName;

            $this->upload->initialize($config);

            if ($this->upload->do_upload('images[]')) {
                $this->upload->data();
            } else {
                return false;
            }
        }

        return $images;
    }

A simple one without using Regex (which I don't like for its poor readability):

bool IsValidEmail(string email)
{
    string emailTrimed = email.Trim();

    if (!string.IsNullOrEmpty(emailTrimed))
    {
        bool hasWhitespace = emailTrimed.Contains(" ");

        int indexOfAtSign = emailTrimed.LastIndexOf('@');

        if (indexOfAtSign > 0 && !hasWhitespace)
        {
            string afterAtSign = emailTrimed.Substring(indexOfAtSign + 1);

            int indexOfDotAfterAtSign = afterAtSign.LastIndexOf('.');

            if (indexOfDotAfterAtSign > 0 && afterAtSign.Substring(indexOfDotAfterAtSign).Length > 1)
                return true;
        }
    }

    return false;
}

Examples:

• IsValidEmail("@b.com") // false
• IsValidEmail("[email protected]") // false
• IsValidEmail("a@bcom") // false
• IsValidEmail("a.b@com") // false
• IsValidEmail("a@b.") // false
• IsValidEmail("a [email protected]") // false
• IsValidEmail("a@b c.com") // false
• IsValidEmail("[email protected]") // true
• IsValidEmail("[email protected]") // true
• IsValidEmail("[email protected]") // true
• IsValidEmail("[email protected]") // true

It is meant to be simple and therefore it doesn't deal with rare cases like emails with bracketed domains that contain spaces (typically allowed), emails with IPv6 addresses, etc.

In newer versions change was made to the flags: from the documentation:

--extended-insert, -e

Write INSERT statements using multiple-row syntax that includes several VALUES lists. This results in a smaller dump file and speeds up inserts when the file is reloaded.

--opt

This option, enabled by default, is shorthand for the combination of --add-drop-table --add-locks --create-options --disable-keys --extended-insert --lock-tables --quick --set-charset. It gives a fast dump operation and produces a dump file that can be reloaded into a MySQL server quickly.

Because the --opt option is enabled by default, you only specify its converse, the --skip-opt to turn off several default settings. See the discussion of mysqldump option groups for information about selectively enabling or disabling a subset of the options affected by --opt.

--skip-extended-insert

Turn off extended-insert

Basically an index on a table works like an index in a book (that's where the name came from):

Let's say you have a book about databases and you want to find some information about, say, storage. Without an index (assuming no other aid, such as a table of contents) you'd have to go through the pages one by one, until you found the topic (that's a full table scan). On the other hand, an index has a list of keywords, so you'd consult the index and see that storage is mentioned on pages 113-120,231 and 354. Then you could flip to those pages directly, without searching (that's a search with an index, somewhat faster).

Of course, how useful the index will be, depends on many things - a few examples, using the simile above:

• if you had a book on databases and indexed the word "database", you'd see that it's mentioned on pages 1-59,61-290, and 292 to 400. In such case, the index is not much help and it might be faster to go through the pages one by one (in a database, this is "poor selectivity").
• For a 10-page book, it makes no sense to make an index, as you may end up with a 10-page book prefixed by a 5-page index, which is just silly - just scan the 10 pages and be done with it.
• The index also needs to be useful - there's generally no point to index e.g. the frequency of the letter "L" per page.

var Str_txt = '{"theTeam":[{"teamId":"1","status":"pending"},{"teamId":"2","status":"member"},{"teamId":"3","status":"member"}]}';

If you want to add at last position then use this:

var parse_obj = JSON.parse(Str_txt);
parse_obj['theTeam'].push({"teamId":"4","status":"pending"});
Str_txt = JSON.stringify(parse_obj);
Output //"{"theTeam":[{"teamId":"1","status":"pending"},{"teamId":"2","status":"member"},{"teamId":"3","status":"member"},{"teamId":"4","status":"pending"}]}"

If you want to add at first position then use the following code:

var parse_obj = JSON.parse(Str_txt);
parse_obj['theTeam'].unshift({"teamId":"4","status":"pending"});
Str_txt = JSON.stringify(parse_obj);
Output //"{"theTeam":[{"teamId":"4","status":"pending"},{"teamId":"1","status":"pending"},{"teamId":"2","status":"member"},{"teamId":"3","status":"member"}]}"

Anyone who wants to add at a certain position of an array try this:

parse_obj['theTeam'].splice(2, 0, {"teamId":"4","status":"pending"});
Output //"{"theTeam":[{"teamId":"1","status":"pending"},{"teamId":"2","status":"member"},{"teamId":"4","status":"pending"},{"teamId":"3","status":"member"}]}"

Above code block adds an element after the second element.

1. xCode window tab
2. Organizer
3. Right click to the archive you want to get app
4. Show in finder
5. Right click to (ProductName….). xcarchive file
6. Show package contents
7. Products
8. Applications

Finally - THERE IS YOUR .APP PROJECT FILE !

You can put this code in cshtml if you are returning view from controller and you want to increase the length of view bag data while encoding in json in cshtml

@{
    var jss = new System.Web.Script.Serialization.JavaScriptSerializer();
    jss.MaxJsonLength = Int32.MaxValue;
    var userInfoJson = jss.Serialize(ViewBag.ActionObj);
}

var dataJsonOnActionGrid1 = @Html.Raw(userInfoJson);

Now, dataJsonOnActionGrid1 will be accesible on js page and you will get proper result.

Put them in public folder and call it in the view with something like href="{{ asset('public/css/style.css') }}". Note that the public should be included when you call the assets.

There are two ways of doing it:

1. Submit the form to the same page: Handle the submitted form using PHP script. (This can be done by setting the form action to the current page URL.)

   if(isset($_POST['submit'])) {
       // Enter the code you want to execute after the form has been submitted
       // Display Success or Failure message (if any)
     } else {
       // Display the Form and the Submit Button
   }
   

2. Using AJAX Form Submission which is a little more difficult for a beginner than method #1.

We can use attribute android:background in Button xml like below.

android:background="?android:attr/selectableItemBackground"

Or we can use style

style="?android:attr/borderlessButtonStyle" for transparent and shadow less background.

The page is using excanvas - a JS library that simulates the canvas element using IE's VML renderer.

Note that in Internet Explorer 9, the canvas tag is supported natively! See MSDN docs for details...

You should use the csv module to read the tab-separated value file. Do not read it into memory in one go. Each row you read has all the information you need to write rows to the output CSV file, after all. Keep the output file open throughout.

import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows([row[2:4] for _ in range(count)])

or, using the itertools module to do the repeating with itertools.repeat():

from itertools import repeat
import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows(repeat(row[2:4], count))

composer.phar can be ran on its own, no need to prefix it with php. This should solve your problem (being in the difference of bash's $PATH and php's include_path).

I'm not sure what you are doing wrong here, when I build a form using form classes Symfony takes care of selecting the correct option in the list. Here's an example of one of my forms that works.

In the controller for the edit action:

$entity = $em->getRepository('FooBarBundle:CampaignEntity')->find($id);

if (!$entity) {
throw $this->createNotFoundException('Unable to find CampaignEntity entity.');
}


$editForm = $this->createForm(new CampaignEntityType(), $entity);
$deleteForm = $this->createDeleteForm($id);

return $this->render('FooBarBundle:CampaignEntity:edit.html.twig', array(
        'entity'      => $entity,
        'edit_form'   => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    ));

The campaign entity type class (src: Foo\BarBundle\Form\CampaignEntityType.php):

namespace Foo\BarBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
use Doctrine\ORM\EntityRepository;

class CampaignEntityType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder
        ->add('store', 'entity', array('class'=>'FooBarBundle:Store', 'property'=>'name', 'em'=>'my_non_default_em','required'  => true, 'query_builder' => function(EntityRepository $er) {return $er->createQueryBuilder('s')->orderBy('s.name', 'ASC');}))
        ->add('reward');
    }
    public function getName()
    {
        return 'foo_barbundle_campaignentitytype';
    }
}

If you're looking for ES6 OOP implementation of Stack and Queue data-structure with some basic operations (based on linked lists) then it may look like this:

Queue.js

import LinkedList from '../linked-list/LinkedList';

export default class Queue {
  constructor() {
    this.linkedList = new LinkedList();
  }

  isEmpty() {
    return !this.linkedList.tail;
  }

  peek() {
    if (!this.linkedList.head) {
      return null;
    }

    return this.linkedList.head.value;
  }

  enqueue(value) {
    this.linkedList.append(value);
  }

  dequeue() {
    const removedHead = this.linkedList.deleteHead();
    return removedHead ? removedHead.value : null;
  }

  toString(callback) {
    return this.linkedList.toString(callback);
  }
}

Stack.js

import LinkedList from '../linked-list/LinkedList';

export default class Stack {
  constructor() {
    this.linkedList = new LinkedList();
  }

  /**
   * @return {boolean}
   */
  isEmpty() {
    return !this.linkedList.tail;
  }

  /**
   * @return {*}
   */
  peek() {
    if (!this.linkedList.tail) {
      return null;
    }

    return this.linkedList.tail.value;
  }

  /**
   * @param {*} value
   */
  push(value) {
    this.linkedList.append(value);
  }

  /**
   * @return {*}
   */
  pop() {
    const removedTail = this.linkedList.deleteTail();
    return removedTail ? removedTail.value : null;
  }

  /**
   * @return {*[]}
   */
  toArray() {
    return this.linkedList
      .toArray()
      .map(linkedListNode => linkedListNode.value)
      .reverse();
  }

  /**
   * @param {function} [callback]
   * @return {string}
   */
  toString(callback) {
    return this.linkedList.toString(callback);
  }
}

And LinkedList implementation that is used for Stack and Queue in examples above may be found on GitHub here.

You could use animation like this:

-webkit-animation: spin 1s infinite linear;

@-webkit-keyframes spin {
    0%   {-webkit-transform: rotate(0deg)}
    100% {-webkit-transform: rotate(360deg)}
}

$route: This is used for deep-linking URLs to controllers and views (HTML partials) and watches $location.url() in order to map the path from an existing definition of route.

When we use ngRoute, the route is configured with $routeProvider and when we use ui-router, the route is configured with $stateProvider and $urlRouterProvider.

<div ng-view></div>
    $routeProvider
        .when('/contact/', {
            templateUrl: 'app/views/core/contact/contact.html',
            controller: 'ContactCtrl'

Here's a one-liner solution without cheating with a non-JDK library.

List<String> strings = Arrays.asList(list.toString().replaceAll("\\[(.*)\\]", "$1").split(", "));

Yes; copy the string to a char array, sort the char array, then copy that back into a string.

static string SortString(string input)
{
    char[] characters = input.ToArray();
    Array.Sort(characters);
    return new string(characters);
}

A lot of these answers are simplistic, and if someone is beginning WPF, they may not know all of the "ins-and-outs", as it is more complicated than just telling someone "Use .ShowDialog()!". But that is the method (not .Show()) that you want to use in order to block use of the underlying window and to keep the code from continuing until the modal window is closed.

First, you need 2 WPF windows. (One will be calling the other.)

From the first window, let's say that was called MainWindow.xaml, in its code-behind will be:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }
}

Then add your button to your XAML:

<Button Name="btnOpenModal" Click="btnOpenModal_Click" Content="Open Modal" />

And right-click the Click routine, select "Go to definition". It will create it for you in MainWindow.xaml.cs:

private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
}

Within that function, you have to specify the other page using its page class. Say you named that other page "ModalWindow", so that becomes its page class and is how you would instantiate (call) it:

private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
    ModalWindow modalWindow = new ModalWindow();
    modalWindow.ShowDialog();
}

Say you have a value you need set on your modal dialog. Create a textbox and a button in the ModalWindow XAML:

<StackPanel Orientation="Horizontal">
    <TextBox Name="txtSomeBox" />
    <Button Name="btnSaveData" Click="btnSaveData_Click" Content="Save" /> 
</StackPanel>

Then create an event handler (another Click event) again and use it to save the textbox value to a public static variable on ModalWindow and call this.Close().

public partial class ModalWindow : Window
{
    public static string myValue = String.Empty;        
    public ModalWindow()
    {
        InitializeComponent();
    }

    private void btnSaveData_Click(object sender, RoutedEventArgs e)
    {
        myValue = txtSomeBox.Text;
        this.Close();
    }
}

Then, after your .ShowDialog() statement, you can grab that value and use it:

private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
    ModalWindow modalWindow = new ModalWindow();
    modalWindow.ShowDialog();

    string valueFromModalTextBox = ModalWindow.myValue;
}

First of all, a spinner does not support item click events. Calling this method will raise an exception.

You can use setOnItemSelectedListener:

Spinner s1;
s1 = (Spinner)findViewById(R.id.s1);
int selectionCurrent = s1.getSelectedItemPosition();

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            if (selectionCurrent != position){
                // Your code here
            }
            selectionCurrent= position;
        }
    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
        // Your code here
    }
});

If your settings file is in a web app, they will be in teh web.config file (right below your project. If they are in any other type of project, they will be in the app.config file (also below your project).

Edit

As is pointed out in the comments: your design time application settings are in an app.config file for applications other than web applications. When you build, the app.config file is copied to the output directory, and will be named yourexename.exe.config. At runtime, only the file named yourexename.exe.config will be read.

Here is the latest simplest solution - no need to change anything, just add three lines of CSS rules to your container of the div where you wish to center at. I love Flex Box #LoveFlexBox

.main {_x000D_
  /* I changed height to 200px to make it easy to see the alignment. */_x000D_
  height: 200px;_x000D_
  vertical-align: middle;_x000D_
  border: 1px solid #000000;_x000D_
  padding: 2px;_x000D_
  _x000D_
  /* Just add the following three rules to the container of which you want to center at. */_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  justify-content: center;_x000D_
  /* This is true vertical center, no math needed. */_x000D_
}_x000D_
.inner {_x000D_
  border: 1px solid #000000;_x000D_
}_x000D_
.second {_x000D_
  border: 1px solid #000000;_x000D_
}

<div class="main">_x000D_
  <div class="inner">This box should be centered in the larger box_x000D_
    <div class="second">Another box in here</div>_x000D_
  </div>_x000D_
  <div class="inner">This box should be centered in the larger box_x000D_
    <div class="second">Another box in here</div>_x000D_
  </div>_x000D_
</div>

Bonus

the justify-content value can be set to the following few options:

• flex-start, which will align the child div to where the flex flow starts in its parent container. In this case, it will stay on top.

• center, which will align the child div to the center of its parent container. This is really neat, because you don't need to add an additional div to wrap around all children to put the wrapper in a parent container to center the children. Because of that, this is the true vertical center (in the column flex-direction. similarly, if you change the flow-direction to row, it will become horizontally centered.

• flex-end, which will align the child div to where the flex flow ends in its parent container. In this case, it will move to bottom.

• space-between, which will spread all children from the beginning of the flow to the end of the flow. If the demo, I added another child div, to show they are spread out.

• space-around, similar to space-between, but with half of the space in the beginning and end of the flow.

Some code for a variation on this problem. Using the above code got me my click events as needed, but I was then stuck trying to work out which button had been clicked. My scenario is I have a dynamic amount of tab pages. On each tab page are (all dynamically created) 2 charts, 2 DGVs and a pair of radio buttons. Each control has a unique name relative to the tab, but there could be 20 radio buttons with the same name if I had 20 tab pages. The radio buttons switch between which of the 2 graphs and DGVs you get to see. Here is the code for when one of the radio buttons gets checked (There's a nearly identical block that swaps the charts and DGVs back):

   Private Sub radioFit_Components_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

    If sender.name = "radioFit_Components" And sender.visible Then
        If sender.checked Then
            For Each ctrl As Control In TabControl1.SelectedTab.Controls
                Select Case ctrl.Name

You can pass an enum through as a string.

public enum CountType {
    ONE,
    TWO,
    THREE
}

private CountType count;
count = ONE;

String countString = count.name();

CountType countToo = CountType.valueOf(countString);

Given strings are supported you should be able to pass the value of the enum around with no problem.

The matrix you pasted

[[   1,    8,   50],
 [   8,   64,  400],
 [  50,  400, 2500]]

Has a determinant of zero. This is the definition of a Singular matrix (one for which an inverse does not exist)

Here's a Boolean thing:

if (not suffix == "flac" )  or (not suffix == "cue" ):   # WRONG! FAILS
    print  filename + ' is not a flac or cue file'

but

if not (suffix == "flac"  or suffix == "cue" ):     # CORRECT!
       print  filename + ' is not a flac or cue file'

(not a) or (not b) == not ( a and b ) , is false only if a and b are both true

not (a or b) is true only if a and be are both false.

You can try using struct:

import struct
struct.pack('L',longvalue)

This is a simple solution for those who are used to promises and don't want to use any third party libs or timers.

I have been using it in my projects for a while

function waitForElm(selector) {
    return new Promise(resolve => {
        if (document.querySelector(selector)) {
            return resolve(document.querySelector(selector));
        }

        const observer = new MutationObserver(mutations => {
            if (document.querySelector(selector)) {
                resolve(document.querySelector(selector));
                observer.disconnect();
            }
        });

        observer.observe(document.body, {
            childList: true,
            subtree: true
        });
    });
}

To use it:

waitForElm('.some-class').then(elm => console.log(elm.textContent));

or with async/await

const elm = await waitForElm('.some-classs')

I got same error in my application.I am loading many controls in single page.In button click event i am clearing the controls.clearing the controls doesnot release the controls from memory.So dispose the controls from memory. I just commented controls.clear() method and include few lines of code to dispose the controls. Something like this

for each ctl as control in controlcollection

ctl.dispose()

If you guys are looking for a solution for Android, you can use the following code to get the epoch seconds from the timestamp string.

public static long timestampToEpochSeconds(String srcTimestamp) {
    long epoch = 0;

    try {
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            Instant instant = Instant.parse(srcTimestamp);
            epoch = instant.getEpochSecond();
        } else {
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSSSS'Z'", Locale.getDefault());
            sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
            Date date = sdf.parse(srcTimestamp);
            if (date != null) {
                epoch = date.getTime() / 1000;
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    return epoch;
}

Sample input: 2019-10-15T05:51:31.537979Z

Sample output: 1571128673

Just add 'change' listener on your input whose type is file. i.e

<input type="file" id="file_to_upload" name="file_to_upload" />

I have done using jQuery and obviously anyone can use valina JS (as per the requirement).

$("#file_to_upload").change(function() {

            if (this.files.length) {

            alert('file choosen');

            } else {

            alert('file NOT choosen');

            }

    });

The problem was that you needed to add " ' ;" at the end.

You can do this if you want to watch the viewContentLoaded DOM object to change and then do something. using $scope.$on works too but differently especially when you have one page mode on your routing.

 $scope.$watch('$viewContentLoaded', function(){
    // do something
 });

In 11g you can use the undocumented function wm_concat like this:

     select wm_concat(distinct name) as names from demotable group by group_id

I had similar issues when trying to connect to Google's OAuth2 service.

I ended up writing the POST manually, not using WebRequest, like this:

TcpClient client = new TcpClient("accounts.google.com", 443);
Stream netStream = client.GetStream();
SslStream sslStream = new SslStream(netStream);
sslStream.AuthenticateAsClient("accounts.google.com");

{
    byte[] contentAsBytes = Encoding.ASCII.GetBytes(content.ToString());

    StringBuilder msg = new StringBuilder();
    msg.AppendLine("POST /o/oauth2/token HTTP/1.1");
    msg.AppendLine("Host: accounts.google.com");
    msg.AppendLine("Content-Type: application/x-www-form-urlencoded");
    msg.AppendLine("Content-Length: " + contentAsBytes.Length.ToString());
    msg.AppendLine("");
    Debug.WriteLine("Request");
    Debug.WriteLine(msg.ToString());
    Debug.WriteLine(content.ToString());

    byte[] headerAsBytes = Encoding.ASCII.GetBytes(msg.ToString());
    sslStream.Write(headerAsBytes);
    sslStream.Write(contentAsBytes);
}

Debug.WriteLine("Response");

StreamReader reader = new StreamReader(sslStream);
while (true)
{  // Print the response line by line to the debug stream for inspection.
    string line = reader.ReadLine();
    if (line == null) break;
    Debug.WriteLine(line);
}

The response that gets written to the response stream contains the specific error text that you're after.

In particular, my problem was that I was putting endlines between url-encoded data pieces. When I took them out, everything worked. You might be able to use a similar technique to connect to your service and read the actual response error text.

Maybe someone can use it. Find all files which were modified within a certain time frame recursively, just run:

find . -type f -newermt "2013-06-01" \! -newermt "2013-06-20"

Sorted() solution can give you some unexpected results with other strings.

List of other solutions:

Sort letters and make them distinct:

>>> s = "Bubble Bobble"
>>> ''.join(sorted(set(s.lower())))
' belou'

Sort letters and make them distinct while keeping caps:

>>> s = "Bubble Bobble"
>>> ''.join(sorted(set(s)))
' Bbelou'

Sort letters and keep duplicates:

>>> s = "Bubble Bobble"
>>> ''.join(sorted(s))
' BBbbbbeellou'

If you want to get rid of the space in the result, add strip() function in any of those mentioned cases:

>>> s = "Bubble Bobble"
>>> ''.join(sorted(set(s.lower()))).strip()
'belou'

Here's a practical example (build a dataset from your current location):

$ds = new-object System.Data.DataSet
$ds.Tables.Add("tblTest")
[void]$ds.Tables["tblTest"].Columns.Add("Name",[string])
[void]$ds.Tables["tblTest"].Columns.Add("Path",[string])

dir | foreach {
    $dr = $ds.Tables["tblTest"].NewRow()
    $dr["Name"] = $_.name
    $dr["Path"] = $_.fullname
    $ds.Tables["tblTest"].Rows.Add($dr)
}


$ds.Tables["tblTest"]

$ds.Tables["tblTest"] is an object that you can manipulate just like any other Powershell object:

$ds.Tables["tblTest"] | foreach {
    write-host 'Name value is : $_.name
    write-host 'Path value is : $_.path
}

From Crockford

By convention, we make a private that variable. This is used to make the object available to the private methods. This is a workaround for an error in the ECMAScript Language Specification which causes this to be set incorrectly for inner functions.

JS Fiddle

function usesThis(name) {
    this.myName = name;

    function returnMe() {
        return this;        //scope is lost because of the inner function
    }

    return {
        returnMe : returnMe
    }
}

function usesThat(name) {
    var that = this;
    this.myName = name;

    function returnMe() {
        return that;            //scope is baked in with 'that' to the "class"
    }

    return {
        returnMe : returnMe
    }
}

var usesthat = new usesThat('Dave');
var usesthis = new usesThis('John');
alert("UsesThat thinks it's called " + usesthat.returnMe().myName + '\r\n' +
      "UsesThis thinks it's called " + usesthis.returnMe().myName);

This alerts...

UsesThat thinks it's called Dave

UsesThis thinks it's called undefined

I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.

By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.

Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.

The correct way is to set the BindByName property of OracleCommand to true as below:

var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;

You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post

import java.io.*;


public class FileRead {


    public static void main(String[] args) throws IOException {


        File f=new File("C:\\Documents and Settings\\abc\\Desktop\\abc.pdf");

        OutputStream oos = new FileOutputStream("test.pdf");

        byte[] buf = new byte[8192];

        InputStream is = new FileInputStream(f);

        int c = 0;

        while ((c = is.read(buf, 0, buf.length)) > 0) {
            oos.write(buf, 0, c);
            oos.flush();
        }

        oos.close();
        System.out.println("stop");
        is.close();

    }

}

The easiest way so far. Hope this helps.

To Achieve ellipses for the text use the Text property numberofLines={1} which will automatically truncate the text with an ellipsis you can specify the ellipsizeMode as "head", "middle", "tail" or "clip" By default it is tail

1. You need to use support library 23.2.0 (or) above

2. and RecyclerView height will be wrap_content.

3. recyclerView.setNestedScrollingEnabled(false)

But by doing this the recycler pattern doesn't work. (i.e all the views will be loaded at once because wrap_content needs the height of complete RecyclerView so it will draw all child Views at once. No view will be recycled). Try not to use this pattern unless it is really required. Try to use viewType and add all other views that need to scroll to RecyclerView rather than using RecyclerView in Scrollview. The performance impact will be very high.

To make it simple "it just acts as LinearLayout with all the child views"

(OK, I know you are asking for shrink-wrap, but maybe those home-grown solutions just weren't succinct enough for your liking. :-)

pdf = [(1, 0.1), (2, 0.05), (3, 0.05), (4, 0.2), (5, 0.4), (6, 0.2)]
cdf = [(i, sum(p for j,p in pdf if j < i)) for i,_ in pdf]
R = max(i for r in [random.random()] for i,c in cdf if c <= r)

I pseudo-confirmed that this works by eyeballing the output of this expression:

sorted(max(i for r in [random.random()] for i,c in cdf if c <= r)
       for _ in range(1000))

As an exploration of this topic, I have a presentation titled "Securing TodoMVC Using the Web Cryptography API" (video, code).

It uses the Web Cryptography API to store the todo list encrypted in localStorage by password protecting the application and using a password derived key for encryption. If you forget or lose the password, there is no recovery. (Disclaimer - it was a POC and not intended for production use.)

As the other answers state, this is still susceptible to XSS or malware installed on the client computer. However, any sensitive data would also be in memory when the data is stored on the server and the application is in use. I suggest that offline support may be the compelling use case.

In the end, encrypting localStorage probably only protects the data from attackers that have read only access to the system or its backups. It adds a small amount of defense in depth for OWASP Top 10 item A6-Sensitive Data Exposure, and allows you to answer "Is any of this data stored in clear text long term?" correctly.

To create and save an object in a single step, use the create() method.

The correct way to do this is the following (thanks QT Support Team):

CONFIG(debug, debug|release) {
    DESTDIR = build/debug
}
CONFIG(release, debug|release) {
    DESTDIR = build/release
}

OBJECTS_DIR = $$DESTDIR/.obj
MOC_DIR = $$DESTDIR/.moc
RCC_DIR = $$DESTDIR/.qrc
UI_DIR = $$DESTDIR/.u

You have to use active in the label to make it work as mentioned above. But you can use checked="checked" and it will work too. It's not necessary but it's more legible and makes more sense as it is more html format compliance.

I tested your code and works properly. I've added a small demo with another way to print all the data in the map:

ConcurrentHashMap<String, Integer> map = new ConcurrentHashMap<String, Integer>();
map.put("A", 1);
map.put("B", 2);
map.put("C", 3);

for (String key : map.keySet()) {
    System.out.println(key + " " + map.get(key));
}

for (Map.Entry<String, Integer> entry : map.entrySet()) {
    String key = entry.getKey().toString();
    Integer value = entry.getValue();
    System.out.println("key, " + key + " value " + value);
}

If you want to avoid hardcoding your keystore & password in build.gradle, you can use a properties file as explained here: HANDLING SIGNING CONFIGS WITH GRADLE

Basically:

1) create a myproject.properties file at /home/[username]/.signing with such contents:

keystore=[path to]\release.keystore
keystore.password=*********
keyAlias=***********
keyPassword=********

2) create a gradle.properties file (perhaps at the root of your project directory) with the contents:

MyProject.properties=/home/[username]/.signing/myproject.properties

3) refer to it in your build.gradle like this:

    if(project.hasProperty("MyProject.properties")
        && new File(project.property("MyProject.properties")).exists()) {

    Properties props = new Properties()
    props.load(new FileInputStream(file(project.property("MyProject.properties"))))

    signingConfigs {
        release {
            storeFile file(props['keystore'])
            storePassword props['keystore.password']
            keyAlias props['keyAlias']
            keyPassword props['keyPassword']
        }
    }
}

For me I had to manually uninstall mysql

brew uninstall mysql
rm -rf /usr/local/var/mysql
brew install mysql

The only thing that can be work is (if we mention that the passwords are just hashed, without adding any kind of salt to prevent the replay attacks, if it is so you must know the salt)by the way, get an dictionary attack tool, the files of many words, numbers etc. then create two rows, one row is word,number (in dictionary) the other one is hash of the word, and compare the hashes if matches you get it...

that's the only way, without going into cryptanalysis.

Files will be deleted from your app's document directory when the user uninstalls the app. Knowing this, all you have to do is check whether a file exists as the first thing that happens in application:didFinishLaunchingWithOptions:. Afterwards, unconditionally create the file (even if it's just a dummy file).

If the file did not exist at time of check, you know this is the first run since the latest install. If you need to know later in the app, save the boolean result to your app delegate member.

I modified my activate script to source the file .virtualenvrc, if it exists in the current directory, and to save/restore PYTHONPATH on activate/deactivate.

You can find the patched activate script here.. It's a drop-in replacement for the activate script created by virtualenv 1.11.6.

Then I added something like this to my .virtualenvrc:

export PYTHONPATH="${PYTHONPATH:+$PYTHONPATH:}/some/library/path"

In Java 8, for anyone looking now to read file large files line by line,

Stream<String> lines = Files.lines(Paths.get("c:\myfile.txt"));
lines.forEach(l -> {
  // Do anything line by line   
});

No need to close the file according to the docs if you use with:

It is good practice to use the with keyword when dealing with file objects. This has the advantage that the file is properly closed after its suite finishes, even if an exception is raised on the way. It is also much shorter than writing equivalent try-finally blocks:

>>> with open('workfile', 'r') as f:
...     read_data = f.read()
>>> f.closed
True

More here: https://docs.python.org/2/tutorial/inputoutput.html#methods-of-file-objects

$address = str_replace(" ", "+", $address);

Use the above code before the file_get_content. means, use the following code

$address = str_replace(" ", "+", $address);

$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=$region");
$json = json_decode($json);

$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};

and it will work surely. As address does not support spaces it supports only + sign in place of space.

Please see this link for more information on setting the text size in code. Basically it says:

public void setTextSize (int unit, float size)

Since: API Level 1 Set the default text size to a given unit and value. See TypedValue for the possible dimension units. Related XML Attributes

android:textSize Parameters

unit The desired dimension unit.
size The desired size in the given units.

Adding some info to the previous answer from @linusg :

sklearn keeps a release history of all its changes. Think of checking it from time to time. Here is the link to the documentation.

As you can see in the documentation for the version 0.18, a new module was created called model_selection. Therefore it didn't exist in previous versions.

Update sklearn and it will work !

I had the same problem, I was trying to listen the change on some select and actually the problem was I was using the event instead of the event.target which is the select object.

INCORRECT :

$(document).on('change', $("select"), function(el) {
    console.log($(el).val());
});

CORRECT :

$(document).on('change', $("select"), function(el) {
    console.log($(el.target).val());
});

What about having different names for your dev and prod servers? That should avoid any confusions and you'd not have to edit the hosts file every time.

Ok, I solved it by adding the url for the background image at the end of the line.

It seems all you can't get is to show the error at the end of editText. Set your editText width to match that of the parent layout enveloping. Will work just fine.

We can read properties file in spring boot using 3 way

1. Read value from application.properties Using @Value

map key as

public class EmailService {

 @Value("${email.username}")
 private String username;

}

2. Read value from application.properties Using @ConfigurationProperties

In this we will map prefix of key using ConfigurationProperties and key name is same as field of class

  @Component
   @ConfigurationProperties("email")
    public class EmailConfig {

        private String   username;
    }

3. Read application.properties Using using Environment object

public class EmailController {

@Autowired
private Environment env;

@GetMapping("/sendmail")
public void sendMail(){     
    System.out.println("reading value from application properties file  using Environment ");
    System.out.println("username ="+ env.getProperty("email.username"));
    System.out.println("pwd ="+ env.getProperty("email.pwd"));
}

Reference : how to read value from application.properties in spring boot

Look at the methods in the java.io.File class:

File file = new File("yourfileName");
String path = file.getAbsolutePath();

Calling savefig before show() worked for me.

fig ,ax = plt.subplots(figsize = (4,4))
sns.barplot(x='sex', y='tip', color='g', ax=ax,data=tips)
sns.barplot(x='sex', y='tip', color='b', ax=ax,data=tips)
ax.legend(['Male','Female'], facecolor='w')

plt.savefig('figure.png')
plt.show()

If you want to show it in a presentation then consider using requestFullscreen() method

let canvas = document.getElementById("canvas_id");
canvas.requestFullscreen();

that should make it fullscreen whatever the current circumstances are.

also check the support table https://caniuse.com/?search=requestFullscreen

This is probably unpopular way. But here how I do it:

object1 = // object to copy

YourClass *object2 = [[YourClass alloc] init];
object2.property1 = object1.property1;
object2.property2 = object1.property2;
..
etc.

Quite simple and straight forward. :P

This is VanillaJS (unmodified):

// Your code goes here:

As you can see, it's not really a framework or a library. It's just a running gag for framework-loving bosses or people who think you NEED to use a JS framework. It means you just use whatever your (for you own sake: non-legacy) browser gives you (using Vanilla JS when working with legacy browsers is a bad idea).

You can use GET instead of pass, but don't use this method for important values,

function passIDto(IDval){    
window.location.href = "CustomerBasket.php?oridd=" +  IDval ;
}   

In the CustomerBasket.php

<?php
  $value = $_GET["oridd"];
  echo  $value;
?>

Setting the max-width of class tooltip-inner didn´t work for me, I´m using bootstrap 3.2

Some how setting max-width only work if you set the width of parent class (.tooltip).

But then all tooltips become the size you specify. So here´s my solution:

add a Width to the parent class:

.tooltip {
  width:400px;
}

Then you add the max-width and change the display to inline-block, so it will not occupy the entire space

.tooltip-inner {
  max-width: @tooltip-max-width;
  display:inline-block;
}

You could only write one where clause.

 SELECT table1.f_id  FROM table1
 INNER JOIN table2
 ON table2.f_id = table1.f_id
 where table1.f_com_id = '430' AND      
 table1.f_status = 'Submitted' AND table2.f_type = 'InProcess'

You might want to consider using a div element pop-up window that contains an iframe.

jQuery Dialog is a simple way to get started. Just add an iframe as the content.

I don’t know why it's so difficult to find a simple answer like this one...

I myself had to struggle a lot to know this. It's very simple:

• Edit your .vimrc file under the home directory.

• Add this line

  set cindent
  

  in your file where you want to indent properly.

• In normal/command mode type

  10==   (This will indent 10 lines from the current cursor location)
  gg=G   (Complete file will be properly indented)
  

Representing complex HTML documents will be difficult and full of corner cases, but I just wanted to share a couple techniques to show how to get this kind of program started. This answer differs in that it uses data abstraction and the toJSON method to recursively build the result

Below, html2json is a tiny function which takes an HTML node as input and it returns a JSON string as the result. Pay particular attention to how the code is quite flat but it's still plenty capable of building a deeply nested tree structure – all possible with virtually zero complexity

// data Elem = Elem Node_x000D_
_x000D_
const Elem = e => ({_x000D_
  toJSON : () => ({_x000D_
    tagName: _x000D_
      e.tagName,_x000D_
    textContent:_x000D_
      e.textContent,_x000D_
    attributes:_x000D_
      Array.from(e.attributes, ({name, value}) => [name, value]),_x000D_
    children:_x000D_
      Array.from(e.children, Elem)_x000D_
  })_x000D_
})_x000D_
_x000D_
// html2json :: Node -> JSONString_x000D_
const html2json = e =>_x000D_
  JSON.stringify(Elem(e), null, '  ')_x000D_
  _x000D_
console.log(html2json(document.querySelector('main')))

<main>_x000D_
  <h1 class="mainHeading">Some heading</h1>_x000D_
  <ul id="menu">_x000D_
    <li><a href="/a">a</a></li>_x000D_
    <li><a href="/b">b</a></li>_x000D_
    <li><a href="/c">c</a></li>_x000D_
  </ul>_x000D_
  <p>some text</p>_x000D_
</main>

In the previous example, the textContent gets a little butchered. To remedy this, we introduce another data constructor, TextElem. We'll have to map over the childNodes (instead of children) and choose to return the correct data type based on e.nodeType – this gets us a littler closer to what we might need

// data Elem = Elem Node | TextElem Node_x000D_
_x000D_
const TextElem = e => ({_x000D_
  toJSON: () => ({_x000D_
    type:_x000D_
      'TextElem',_x000D_
    textContent:_x000D_
      e.textContent_x000D_
  })_x000D_
})_x000D_
_x000D_
const Elem = e => ({_x000D_
  toJSON : () => ({_x000D_
    type:_x000D_
      'Elem',_x000D_
    tagName: _x000D_
      e.tagName,_x000D_
    attributes:_x000D_
      Array.from(e.attributes, ({name, value}) => [name, value]),_x000D_
    children:_x000D_
      Array.from(e.childNodes, fromNode)_x000D_
  })_x000D_
})_x000D_
_x000D_
// fromNode :: Node -> Elem_x000D_
const fromNode = e => {_x000D_
  switch (e.nodeType) {_x000D_
    case 3:  return TextElem(e)_x000D_
    default: return Elem(e)_x000D_
  }_x000D_
}_x000D_
_x000D_
// html2json :: Node -> JSONString_x000D_
const html2json = e =>_x000D_
  JSON.stringify(Elem(e), null, '  ')_x000D_
  _x000D_
console.log(html2json(document.querySelector('main')))

<main>_x000D_
  <h1 class="mainHeading">Some heading</h1>_x000D_
  <ul id="menu">_x000D_
    <li><a href="/a">a</a></li>_x000D_
    <li><a href="/b">b</a></li>_x000D_
    <li><a href="/c">c</a></li>_x000D_
  </ul>_x000D_
  <p>some text</p>_x000D_
</main>

Anyway, that's just two iterations on the problem. Of course you'll have to address corner cases where they come up, but what's nice about this approach is that it gives you a lot of flexibility to encode the HTML however you wish in JSON – and without introducing too much complexity

In my experience, you could keep iterating with this technique and achieve really good results. If this answer is interesting to anyone and would like me to expand upon anything, let me know ^_^

Related: Recursive methods using JavaScript: building your own version of JSON.stringify

My recommendation is to save the data to database with Line breaks instead parsing it with nl2br. You should use nl2br in output not input.

For your question, you can use php or javascript:

PHP:

str_replace('<br />', "\n", $textarea);

jQuery:

$('#myTextArea').val($('#myTextArea').val().replace(@<br />@, "\N"));

Are you asking about the Server header value in the response? You can try changing that with an add_header directive, but I'm not sure if it'll work. http://wiki.codemongers.com/NginxHttpHeadersModule

You can use the checked attribute for this:

<input type="radio" checked="checked">

This problem is usually caused by writing to a connection that had already been closed by the peer. In this case it could indicate that the user cancelled the download for example.

By default, when a flutter app gets installed, the app name on the launcher is your Flutter project name. To change that to your desired application name on Android or iOS both, you need to change AndroidManifest.xml and Info.plist respectively. here is a two way to achieve this

1 By plugin

You can use a flutter rename plugin. It helps you to change your flutter project's AppName and BundleId for different platforms, currently only available for iOS, Android and macOS

You can change the bundleId and appName in the following steps

Default Usage if you dont pass -t or --target parameter it will try to rename all available platform project folders inside flutter project.

Run this command inside your flutter project root.

pub global run rename --bundleId com.onatcipli.networkUpp
pub global run rename --appname "Test App Name"

Custom Usage if you want to run commands directly (without using pub global run) ensure you add system catche bin directory to your path

rename --appname yourappname -t ios

or

pub global run rename --appname yourappname --target macOS

To target a specific platform use the "--target" option. e.g.

pub global run rename --bundleId com.example.android.app --target android

2 By manual

For Android

App Name is reflected under Android>src>main>Androidmanifest.xml The label name in the Android manifest is responsible for giving the App Name for Android Application

Go to AndroidManifest.xml, find <application> tag. Change its android:label property with your desired app name.

Navigate to the : android/app/src/main/AndroidManifest.xml

The Androidmanifest.xml can now be modified. Choose the

<application
  android:name="io.flutter.app.FlutterApplication"
  android:label="YourAppName"
  android:icon="@mipmap/ic_launcher">

For Package Name

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your.package.name">

This portion represents the actual Android file naming system. Important information like Launcher Icon and App name can be controlled here. Modify the android:label to change the App Name only.

For iOS

For iOS, open info.plist. Change CFBundleName (Bundle Name).

Go to the Xcode project folder and open Info.plist for edit (in Xcode you can choose Open As > Source Code in the file context menu). All we need is to edit the value for key CFBundleName. It’s a user-visible short name for the bundle.

Navigate to the: project/ios/Runner/Info.plist

Find the CFBundleName <key>. This denotes the Key that holds the app name. The app name now can be changed by modifying the <String> </String> below that.

<key>CFBundleName</key>
<string>YouAppName</string>

That’s it. By having these changes, That’s achieved, an updated application name in the launcher when an app gets installed on a device. your new app name will be displayed on your phone now.

You can also create a borderless window, and make the borders and title bar yourself

There is a firewall blocking the connection or the process that is hosting the service is not listening on that port. Or it is listening on a different port.

LinearLayout : A layout that organizes its children into a single horizontal or vertical row. It creates a scrollbar if the length of the window exceeds the length of the screen.It means you can align views one by one (vertically/ horizontally).

RelativeLayout : This enables you to specify the location of child objects relative to each other (child A to the left of child B) or to the parent (aligned to the top of the parent). It is based on relation of views from its parents and other views.

WebView : to load html, static or dynamic pages.

For more information refer this link:http://developer.android.com/guide/topics/ui/layout-objects.html

A lot of the code here was very helpful, but I cleaned it up for my purposes and added some tests. Here's what I ended up with:

using System;
using System.Linq;
using System.Net;
using System.Web;

public class RequestHelpers
{
    public static string GetClientIpAddress(HttpRequestBase request)
    {
        try
        {
            var userHostAddress = request.UserHostAddress;

            // Attempt to parse.  If it fails, we catch below and return "0.0.0.0"
            // Could use TryParse instead, but I wanted to catch all exceptions
            IPAddress.Parse(userHostAddress);

            var xForwardedFor = request.ServerVariables["X_FORWARDED_FOR"];

            if (string.IsNullOrEmpty(xForwardedFor))
                return userHostAddress;

            // Get a list of public ip addresses in the X_FORWARDED_FOR variable
            var publicForwardingIps = xForwardedFor.Split(',').Where(ip => !IsPrivateIpAddress(ip)).ToList();

            // If we found any, return the last one, otherwise return the user host address
            return publicForwardingIps.Any() ? publicForwardingIps.Last() : userHostAddress;
        }
        catch (Exception)
        {
            // Always return all zeroes for any failure (my calling code expects it)
            return "0.0.0.0";
        }
    }

    private static bool IsPrivateIpAddress(string ipAddress)
    {
        // http://en.wikipedia.org/wiki/Private_network
        // Private IP Addresses are: 
        //  24-bit block: 10.0.0.0 through 10.255.255.255
        //  20-bit block: 172.16.0.0 through 172.31.255.255
        //  16-bit block: 192.168.0.0 through 192.168.255.255
        //  Link-local addresses: 169.254.0.0 through 169.254.255.255 (http://en.wikipedia.org/wiki/Link-local_address)

        var ip = IPAddress.Parse(ipAddress);
        var octets = ip.GetAddressBytes();

        var is24BitBlock = octets[0] == 10;
        if (is24BitBlock) return true; // Return to prevent further processing

        var is20BitBlock = octets[0] == 172 && octets[1] >= 16 && octets[1] <= 31;
        if (is20BitBlock) return true; // Return to prevent further processing

        var is16BitBlock = octets[0] == 192 && octets[1] == 168;
        if (is16BitBlock) return true; // Return to prevent further processing

        var isLinkLocalAddress = octets[0] == 169 && octets[1] == 254;
        return isLinkLocalAddress;
    }
}

Assuming you have:

HashMap<Key, Value> map; // Assigned or populated somehow.

For a list of values:

List<Value> values = new ArrayList<Value>(map.values());

For a list of keys:

List<Key> keys = new ArrayList<Key>(map.keySet());

Note that the order of the keys and values will be unreliable with a HashMap; use a LinkedHashMap if you need to preserve one-to-one correspondence of key and value positions in their respective lists.

I was having the same "Class [class name] not found" error message, but it wasn't a namespace issue. All my namespaces were set up correctly. I even tried composer dump-autoload and it didn't help me.

Surprisingly (to me) I then did composer dump-autoload -o which according to Composer's help, "optimizes PSR0 and PSR4 packages to be loaded with classmaps too, good for production." Somehow doing it that way got composer to behave and include the class correctly in the autoload_classmap.php file.

Newer versions of Python for Windows come with the pip package manager. (source)

pip is already installed if you're using Python 2 >=2.7.9 or Python 3 >=3.4

Use that to install packages:

cd C:\Python\Scripts\
pip.exe install <package-name>

So in your case it'd be:

pip.exe install mechanize
