Programs & Examples On #Tkmessagebox

You need not to use even the package "tcltk". You can simply do as shown below:

write.csv(x, file = "c:\\myname\\yourfile.csv", row.names = FALSE)

Give your path inspite of "c:\myname\yourfile.csv".

This code may be helpful for you.

from tkinter import filedialog
from tkinter import *
root = Tk()
root.withdraw()
folder_selected = filedialog.askdirectory()

You can use the root.configure(background='your colour') example:- import tkinter root=tkiner.Tk() root.configure(background='pink')

The code you presented is fine! You just need to explicitly create the "other window in the background" and hide it, with this code:

import Tkinter
window = Tkinter.Tk()
window.wm_withdraw()

Right before your messagebox.

Although other answers include some of the following information, this is the absolute minimum that needs to be changed on EC2 instances, specifically regarding deployment of large WAR files, and is the least likely to cause issues during future updates. I've been running into these limits about every other year due to the ever-increasing size of the Jenkins WAR file (now ~72MB).

More specifically, this answer is applicable if you encounter a variant of the following error in catalina.out:

SEVERE [https-jsse-nio-8443-exec-17] org.apache.catalina.core.ApplicationContext.log HTMLManager:
FAIL - Deploy Upload Failed, Exception:
[org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException:
the request was rejected because its size (75333656) exceeds the configured maximum (52428800)]

On Amazon EC2 Linux instances, the only file that needs to be modified from the default installation of Tomcat (sudo yum install tomcat8) is:

/usr/share/tomcat8/webapps/manager/WEB-INF/web.xml

By default, the maximum upload size is exactly 50MB:

<multipart-config>
  <!-- 50MB max -->
  <max-file-size>52428800</max-file-size>
  <max-request-size>52428800</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

There are only two values that need to be modified (max-file-size and max-request-size):

<multipart-config>
  <!-- 100MB max -->
  <max-file-size>104857600</max-file-size>
  <max-request-size>104857600</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

When Tomcat is upgraded on these instances, the new version of the manager web.xml will be placed in web.xml.rpmnew, so any modifications to the original file will not be overwritten during future updates.

simple java code  for change file permission in java  

   String path="D:\\file\\read.txt";
        File file=new File(path);
        if (file.exists()) {
            System.out.println("read="+file.canRead());
            System.out.println("write="+file.canWrite());
            System.out.println("Execute="+file.canExecute());
            file.setReadOnly();
        }     

Reference : how to change file permission in java

There could be many reasons for this. A few that come up quickly to my mind:

1. Did you call this routine AFTER InitializeComponent()?
2. Is the path syntax you are using correct? Does it work if you try it in the debugger? Try using backslash (\) instead of Slash (/) and see.
3. This may be due to side-effects of some other code in your form. Try using the same code in a blank Form (with just the constructor and this function) and check.

Just set the view as null that will close the AlertDialog simple.

You can kill a (SIGTERM) a windows process that was started from Java by calling the destroy method on the Process object. You can also kill any child Processes (since Java 9).

The following code starts a batch file, waits for ten seconds then kills all sub-processes and finally kills the batch process itself.

ProcessBuilder pb = new ProcessBuilder("cmd /c my_script.bat"));
Process p = pb.start();
p.waitFor(10, TimeUnit.SECONDS);

p.descendants().forEach(ph -> {
    ph.destroy();
});

p.destroy();

Any reason you're not just using a simple for...in loop?

var sample = { a: 1 , b: 2 , c:3 };
var summed = 0;

for (var key in sample) {
    summed += sample[key];
};

I know its an old question, however, I thought it might be helpful to offer another solution.

equivalent of AngularJS of this

<div *ng-for="#item of itemsList" *ng-if="conditon(item)"></div>

in Angular 2+ you cant use *ngFor and *ngIf on a same element, so it will be following:

<div *ngFor="let item of itemsList">
     <div *ngIf="conditon(item)">
     </div>
</div>

and if you can not use as internal container use ng-container instead. ng-container is useful when you want to conditionally append a group of elements (ie using *ngIf="foo") in your application but don't want to wrap them with another element.

Supposing your date is today. Hope this helps you.

DateTime dt = DateTime.Today;

string thisMonth= dt.ToString("MMMM");

Console.WriteLine(thisMonth);

If you install the composer as global on Ubuntu, you just need to find the composer location.

Use command

type composer

or

where composer

For Mac users, use command:

which composer

and then just remove the folder using rm command.

Misconceptions about performance and poor JVM optimizations would be my guess. I say misconceptions about performance because there are some Java ports of C++ games that perform faster than their C++ counterparts (see Jake 2). The real problem, IMHO, is that many Java programmers aren't focused so much on bleeding edge performance as they are with ease of use and understandability/maintainability of code. On the C/C++ side of things you're essentially coding in a slightly higher level assembly language and its about as close to the hardware as you can get without writing in assembly or straight machine code.

Here is a full example on how to transform your date in different types:

Date date = Calendar.getInstance().getTime();

    // Display a date in day, month, year format
    DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
    String today = formatter.format(date);
    System.out.println("Today : " + today);

    // Display date with day name in a short format
    formatter = new SimpleDateFormat("EEE, dd/MM/yyyy");
    today = formatter.format(date);
    System.out.println("Today : " + today);

    // Display date with a short day and month name
    formatter = new SimpleDateFormat("EEE, dd MMM yyyy");
    today = formatter.format(date);
    System.out.println("Today : " + today);

    // Formatting date with full day and month name and show time up to
    // milliseconds with AM/PM
    formatter = new SimpleDateFormat("EEEE, dd MMMM yyyy, hh:mm:ss.SSS a");
    today = formatter.format(date);
    System.out.println("Today : " + today);

Why not go simple and use the tilde ~ operator?

  return File("~/Content/images/topbanner.png", "image/png");

According to protocol documentation there are at least three options website designers can use to inform sitemap.xml location to search engines:

• Informing each search engine of the location through their provided interface
• Adding url to the robots.txt file
• Submiting url to search engines through http

So, unless they have chosen to publish the sitemap location on their robots.txt file, you cannot really know where they have put their sitemap.xml files.

Mysql query for search coordinates with distance limit and where condition

SELECT , ( 3959 acos( cos( radians('28.5850154') ) cos( radians(lat) ) cos( radians( lng ) - radians('77.07207489999999') ) + sin( radians('28.5850154') ) * sin( radians( lat ) ) ) ) AS distance FROM `Wo_Products` WHERE `active` = '1' HAVING distance < 5

if (!secondaryPassword.equals(initialPassword)) 

Simplest: dump the whole collection into a Set (using the Set(Collection) constructor or Set.addAll), then see if the Set has the same size as the ArrayList.

List<Integer> list = ...;
Set<Integer> set = new HashSet<Integer>(list);

if(set.size() < list.size()){
    /* There are duplicates */
}

Update: If I'm understanding your question correctly, you have a 2d array of Block, as in

Block table[][];

and you want to detect if any row of them has duplicates?

In that case, I could do the following, assuming that Block implements "equals" and "hashCode" correctly:

for (Block[] row : table) {
   Set set = new HashSet<Block>(); 
   for (Block cell : row) {
      set.add(cell);
   }
   if (set.size() < 6) { //has duplicate
   }
}

I'm not 100% sure of that for syntax, so it might be safer to write it as

for (int i = 0; i < 6; i++) {
   Set set = new HashSet<Block>(); 
   for (int j = 0; j < 6; j++)
    set.add(table[i][j]);
 ...

Set.add returns a boolean false if the item being added is already in the set, so you could even short circuit and bale out on any add that returns false if all you want to know is whether there are any duplicates.

Each column has like() method, which can be used in query.filter(). Given a search string, add a % character on either side to search as a substring in both directions.

tag = request.form["tag"]
search = "%{}%".format(tag)
posts = Post.query.filter(Post.tags.like(search)).all()

I was installing appium by npm install -g appium and getting the same error on Windows 10.

Below command worked for me:

npm --add-python-to-path='true' --debug install --global windows-build-tools

After DAYS of digging, someone on IRC suggested that I try to use the

Windows 7.1 SDK Command Prompt

Shortcut (links to C:\Windows\System32\cmd.exe /E:ON /V:ON /T:0E /K "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd"). I think you MUST have the older 7.1 SDK (even on Windows 8.1) because the newer ones use msbuild.exe instead of vcbuild.exe which is what node-gyp wants even though it's twice as old as node at this point :/

Once in that prompt, I had to run the following to get x86 context because the compiler was throwing as error otherwise about architecture:

setenv.cmd /Release /x86

THEN I was able to successfully run npm commands that were trying to use node-gyp to recompile things.

It is simple to calculate by diagramming function calls. Simply add the function calls for each value of n and look at how the number grows.

The Big O is O(Z^n) where Z is the golden ratio or about 1.62.

Both the Leonardo numbers and the Fibonacci numbers approach this ratio as we increase n.

Unlike other Big O questions there is no variability in the input and both the algorithm and implementation of the algorithm are clearly defined.

There is no need for a bunch of complex math. Simply diagram out the function calls below and fit a function to the numbers.

Or if you are familiar with the golden ratio you will recognize it as such.

This answer is more correct than the accepted answer which claims that it will approach f(n) = 2^n. It never will. It will approach f(n) = golden_ratio^n.

2 (2 -> 1, 0)

4 (3 -> 2, 1) (2 -> 1, 0)

8 (4 -> 3, 2) (3 -> 2, 1) (2 -> 1, 0)
            (2 -> 1, 0)


14 (5 -> 4, 3) (4 -> 3, 2) (3 -> 2, 1) (2 -> 1, 0)
            (2 -> 1, 0)

            (3 -> 2, 1) (2 -> 1, 0)

22 (6 -> 5, 4)
            (5 -> 4, 3) (4 -> 3, 2) (3 -> 2, 1) (2 -> 1, 0)
                        (2 -> 1, 0)

                        (3 -> 2, 1) (2 -> 1, 0)

            (4 -> 3, 2) (3 -> 2, 1) (2 -> 1, 0)

For those interested, this is code for creating SHA-256 hash using sjcl:

import sjcl from 'sjcl'

const myString = 'Hello'
const myBitArray = sjcl.hash.sha256.hash(myString)
const myHash = sjcl.codec.hex.fromBits(myBitArray)

Your query translates to

SELECT * FROM table WHERE id='1' or id='2' or id='3' or id='4';

It will only return the results that match it.

One way of solving it avoiding the complexity would be, chaning the datatype to SET. Then you could use, FIND_IN_SET

SELECT * FROM table WHERE FIND_IN_SET('1', id);

Environment.SetEnvironmentVariable("Variable name", value, EnvironmentVariableTarget.User);

1. Removing whitespace from the entire file being edited:

Preferences -> Java -> Editors -> Save Actions -> check Perform the selected actions on save -> check Additional actions -> click Configure.. -> go to Code organizing tab -> check Remove trailing whitespace -> select All lines.

2. Removing whitespace only from the lines I changed:

Preferences -> Java -> Editor -> Save Actions -> check "Perform the selected actions on save -> check Format source code -> select Format edited lines.

Note it is not necessary to click Configure the formatter settings on the Formatter page - all the code styles automatically include removing trailing whitespace. At least I couldn't find a setting for this in Formatter configuration, and it worked out of the box for built-in Java Conventions, Eclipse, Eclipse 2.1 styles, as well as GoogleStyle.

When using this set-up, you obviously need to also turn off the solution to part 1 of the question.

Eclipse version checked: 4.5.2, 4.11

You have to use the jquery's text() function. What it does is:

Get the combined text contents of all matched elements.

The result is a string that contains the combined text contents of all matched elements. This method works on both HTML and XML documents. Cannot be used on input elements. For input field text use the val attribute.

For example:

Find the text in the first paragraph (stripping out the html), then set the html of the last paragraph to show it is just text (the bold is gone).

var str = $("p:first").text();
$("p:last").html(str);

Test Paragraph.

Test Paragraph.

With your markup you have to do:

$('a#a_tbnotesverbergen').text('new text');

and it will result in

<a id="a_tbnotesverbergen" href="#nothing">new text</a>

The error shows that the machine does not have enough memory to read the entire CSV into a DataFrame at one time. Assuming you do not need the entire dataset in memory all at one time, one way to avoid the problem would be to process the CSV in chunks (by specifying the chunksize parameter):

chunksize = 10 ** 6
for chunk in pd.read_csv(filename, chunksize=chunksize):
    process(chunk)

The chunksize parameter specifies the number of rows per chunk. (The last chunk may contain fewer than chunksize rows, of course.)

pandas >= 1.2

read_csv with chunksize returns a context manager, to be used like so:

chunksize = 10 ** 6
with pd.read_csv(filename, chunksize=chunksize) as reader:
    for chunk in reader:
        process(chunk)

See GH38225

In my case, the function CString was not found. But adding an empty string to the value works, too.

Dim Test As Integer, Test2 As Variant
Test = 10
Test2 = Test & ""
//Test2 is now "10" not 10

You can use the COALESCE function to automatically return null values as 0. Syntax is as shown below:

SELECT COALESCE(total_amount, 0) from #Temp1

You can also try

System.Environment.GetEnvironmentVariable("UserName");

let test = function() {
    return "Hello world"
};
exports.test = test;

Another easy way is to use 2 premade sizes and pass them as parameter when calling the function in your html. use: 'lg' for large modals with width 900px 'sm' for small modals with width 300px or passing no parameter you use the default size which is 600px.

example code:

$scope.openModal = function (size) {
var modal = $modal.open({
                templateUrl: "/partials/welcome",
                controller: "welcomeCtrl",
                backdrop: "static",
                scope: $scope,
                size: size,
            });
modal.result.then(
        //close
        function (result) {
            var a = result;
        },
        //dismiss
        function (result) {
            var a = result;
        });
};

and in the html I would use something like the following:

<button ng-click="openModal('lg')">open Modal</button>  

2017 Update I guess. textarea worked fine for me using Spring, Bootstrap and a bunch of other things. Got the SOAP payload stored in a DB, read by Spring and push via Spring-MVC. xmp didn't work at all.

Check out JButton documentation. Take special attention to setBackground and setForeground methods inherited from JComponent.

Something like:

for(int i=1;i<=9;i++)
{
    JButton btn = new JButton(String.valueOf(i));
    btn.setBackground(Color.BLACK);
    btn.setForeground(Color.GRAY);
    p3.add(btn);
}

As the main question:

Anybody know why this is not allowed?

is still not answered, I did a quick search and found a relatively new addition from a MySQL developer at MySQL Bugs:

[17 Mar 2017 15:11] Ståle Deraas

Posted by developer:

This is indeed a valid feature request, and at first glance it might seem trivial to add. But TEXT/BLOBS values are not stored directly in the record buffer used for reading/updating tables. So it is a bit more complex to assign default values for them.

This is no definite answer, but at least a starting point for the why question.

In the mean time, I'll just code around it and either make the column nullable or explicitly assign a (default '') value for each insert from the application code...

My solution (example with a random mp4 video file):

1. Set a file to device:

   adb push /home/myuser/myVideoFile.mp4 /storage/emulated/legacy/
   

2. Get a file from device:

   adb pull /storage/emulated/legacy/myVideoFile.mp4 
   

For retrieve the path in the code:

String myFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myVideoFile.mp4";

This is all. This solution doesn't give permission problems and it works fine.

Last point: I wanted to change the video metadata information. If you want to write into your device you should change the permission in the AndroidManifest.xml. Add this line:

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

Match any single character

• Use the dot . character as a wildcard to match any single character.

Example regex: a.c

abc   // match
a c   // match
azc   // match
ac    // no match
abbc  // no match

Match any specific character in a set

• Use square brackets [] to match any characters in a set.
• Use \w to match any single alphanumeric character: 0-9, a-z, A-Z, and _ (underscore).
• Use \d to match any single digit.
• Use \s to match any single whitespace character.

Example 1 regex: a[bcd]c

abc   // match
acc   // match
adc   // match
ac    // no match
abbc  // no match

Example 2 regex: a[0-7]c

a0c   // match
a3c   // match
a7c   // match
a8c   // no match
ac    // no match
a55c  // no match

Match any character except ...

Use the hat in square brackets [^] to match any single character except for any of the characters that come after the hat ^.

Example regex: a[^abc]c

aac   // no match
abc   // no match
acc   // no match
a c   // match
azc   // match
ac    // no match
azzc  // no match

(Don't confuse the ^ here in [^] with its other usage as the start of line character: ^ = line start, $ = line end.)

Match any character optionally

Use the optional character ? after any character to specify zero or one occurrence of that character. Thus, you would use .? to match any single character optionally.

Example regex: a.?c

abc   // match
a c   // match
azc   // match
ac    // match
abbc  // no match

Using zsh you can simply use:

if [[ $(false)? -eq 1 ]]; then echo "yes" ;fi

When using bash & set -e is on you can use:

false || exit_code=$?
if [[ ${exit_code} -ne 0 ]]; then echo ${exit_code}; fi

Using Double.parseDouble() without surrounding try/catch block can cause potential NumberFormatException had the input double string not conforming to a valid format.

Guava offers a utility method for this which returns null in case your String can't be parsed.

https://google.github.io/guava/releases/19.0/api/docs/com/google/common/primitives/Doubles.html#tryParse(java.lang.String)

Double valueDouble = Doubles.tryParse(aPotentiallyCorruptedDoubleString);

In runtime, a malformed String input yields null assigned to valueDouble

 set host=%COMPUTERNAME%
 echo %host%

This one enough. no need of extra loops of big coding.

Something that worked for me, but still think there should be a better solution:

$ git revert <commit_id>
$ git reset HEAD~1 --hard

Just leave the change you want to discard in the other commit, check others out

$ git commit --amend // or stash and rebase to <commit_id> to amend changes

void foo<TOne, TTwo>() 
   where TOne : BaseOne
   where TTwo : BaseTwo

As a general solution to install Python packages with binary dependencies [1] on Debian/Ubuntu:

sudo apt-get build-dep python-ldap
# installs system dependencies (but not the package itself)
pew workon my_virtualenv # enter your virtualenv
pip install python-ldap

You'll have to check the name of your Python package on Ubuntu versus PyPI. In this case they're the same.

Obviously doesn't work if the Python package is not in the Ubuntu repos.

I wanted to just be able to break out of a block - sort of like a forward goto, not really related to a loop. In fact, I want to break of of a block that is in a loop without terminating the loop. To do that, I made the block a one-iteration loop:

for b in 1..2 do
    puts b
    begin
        puts 'want this to run'
        break
        puts 'but not this'
    end while false
    puts 'also want this to run'
end

Hope this helps the next googler that lands here based on the subject line.

All content in src/test/resources is copied into target/test-classes folder. So to get file from test resources during maven build you have to load it from test-classes folder, like that:

Paths.get(
    getClass().getProtectionDomain().getCodeSource().getLocation().toURI()
).resolve(
    Paths.get("somefile")
).toFile()

Break down:

1. getClass().getProtectionDomain().getCodeSource().getLocation().toURI() - give you URI to target/test-classes.
2. resolve(Paths.get("somefile")) - resolves someFile to target/test-classes folder.

Maybe it's too late, but in version 2.1 of TypeScript you can use key of like this:

interface Person {
    name: string;
    age: number;
    location: string;
}

type K1 = keyof Person; // "name" | "age" | "location"
type K2 = keyof Person[];  // "length" | "push" | "pop" | "concat" | ...
type K3 = keyof { [x: string]: Person };  // string

Before running the script, you should check first line of the shell script for the interpreter.

Eg: if scripts starts with /bin/bash , run the script using the below command "bash script_name.sh"

if script starts with /bin/sh, run the script using the below command "sh script_name.sh"

./sample.sh - This will detect the interpreter from the first line of the script and run.

Different Linux distributions having different shells as default.

Needs to be:

if (document.forms[0].elements["checkAddress"].checked == true)

Assuming you have one form, otherwise use the form name.

As a side note, don't call the element and the function in the same name it can cause weird conflicts.

Hi I needed to do the same thing! Don't ask why but I was generating a html using python and needed a way to loop through items in a list and have each item take on a row of its own WITHIN A SINGLE CELL of a table.

I found that the br tag worked well for me. For example:

<!DOCTYPE html>
<HTML>
    <HEAD>
        <TITLE></TITLE>
    </HEAD>
    <BODY>
  <TABLE>
            <TR>
                <TD>
                    item 1 <BR>
                    item 2 <BR>
                    item 3 <BR>
                    item 4 <BR>
                </TD>
            </TR>
        </TABLE>
  </BODY>

This will produce the output that I wanted.

If we have this variables:

var counter int = 5
var message string  = "Hello"
var factor float32 = 4.2
var enabled bool = false

1: fmt.Printf %T format : to use this feature you should import "fmt"

fmt.Printf("%T \n",factor )   // factor type: float32

2: reflect.TypeOf function : to use this feature you should import "reflect"

fmt.Println(reflect.TypeOf(enabled)) // enabled type:  bool

3: reflect.ValueOf(X).Kind() : to use this feature you should import "reflect"

fmt.Println(reflect.ValueOf(counter).Kind()) // counter type:  int

It would probably be easiest to implement this using JavaScript ... Here's a JQuery script to demo ... As the others mentioned ... we have a class named 'active' to indicate the active tab - NOT the pseudo-class ':active.' We could have just as easily named it anything though ... selected, current, etc., etc.

I like to create a boolean and then use that in a logical if.

//kick unvalidated users to the login page
var onLoginPage = (window.location.href.indexOf("login") > -1);

if (!onLoginPage) {
  console.log('redirected to login page');
  window.location = "/login";
} else {
  console.log('already on the login page');
}

Try this, working fine -

$array = json_decode(json_encode($array), true);

I tried scrolling="no" in my current browser (Google Chrome Version 60.0.3112.113 (Official Build) (64-bit)) and that didn't work. However, scroll="no" did work. Might be worth trying

Simulators simulate processes and it would be transformed into the equivalent process to your process statement. Simulation time implies the use of wait for or after when driving events for sensitivity clauses or sensitivity lists.

Regarding the performance concern, it is very likely that this method is theoretically slower than a linear approach. However, in reality, most of the time we are not dealing with the data set that is big enough to make any difference.

If performance is a main concern, Seattle Leonard's answer should give you linear time complexity. Alternatively, you may also consider to start with a different data structure that returns the max value item at constant time.

Import the following class:

#import <QuartzCore/QuartzCore.h> 

//Code for setting the grey color for the border of the text field

[[textField layer] setBorderColor:[[UIColor colorWithRed:171.0/255.0
                                                   green:171.0/255.0
                                                    blue:171.0/255.0
                                                   alpha:1.0] CGColor]];

Replace 171.0 with the respective color number as required.

The best way to install the Zip extension in php7.2 on CentOS would be as below:

1. Find the available extention by searching with yum command

   yum search zip

2. This will list all the zip packages. We need to look for the php7.2 zip package

3. Then if your php version is 7.2 then run the command

   yum install ea-php72-php-zip

This will definetly resolve your issue.

You must feed the DOMDocument a version of your HTML with a header that make sense. Just like HTML5.

$profile ='<?xml version="1.0" encoding="'.$_encoding.'"?>'. $html;

maybe is a good idea to keep your html as valid as you can, so you don't get into issues when you'll start query... around :-) and stay away from htmlentities!!!! That's an an necessary back and forth wasting resources. keep your code insane!!!!

Here are two other solutions

When a module is not yours - try to install types from @types:

npm install -D @types/module-name

If the above install errors - try changing import statements to require:

// import * as yourModuleName from 'module-name';
const yourModuleName = require('module-name');

To add to rcs' answer, if you want to use position_dodge() with geom_bar() when x is a POSIX.ct date, you must multiply the width by 86400, e.g.,

ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) + 
 geom_bar(position = "dodge", stat = 'identity') +
 geom_text(aes(label=Number), position=position_dodge(width=0.9*86400), vjust=-0.25)

How about this?

public static bool IsInteger(double number) {
    return number == Math.Truncate(number);
}

Same code for decimal.

Mark Byers made a good point, actually: this may not be what you really want. If what you really care about is whether a number rounded to the nearest two decimal places is an integer, you could do this instead:

public static bool IsNearlyInteger(double number) {
    return Math.Round(number, 2) == Math.Round(number);
}

Another way of reading Excel including the new format xlsx could be the package speedR (https://r-forge.r-project.org/projects/speedr/). It is an interactive and visual data importer. Besides importing you can filter(subset) the existing objects from the R workspace.

Well, it's not a single statement, but it's about as close as you can get with oracle:

BEGIN
   FOR R IN (SELECT owner, table_name FROM all_tables WHERE owner='TheOwner') LOOP
      EXECUTE IMMEDIATE 'grant select on '||R.owner||'.'||R.table_name||' to TheUser';
   END LOOP;
END; 

Try:

which( !is.na(p), arr.ind=TRUE)

Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:

> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3

[[2]]
[1] 4 7

[[3]]
integer(0)

[[4]]
[1] 5

[[5]]
integer(0)

Or even with smushing together with paste:

lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")

The output from which function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:

> which( !is.na(p), arr.ind=TRUE)
     row col
[1,]   1   2
[2,]   1   3
[3,]   2   4
[4,]   4   5
[5,]   2   7

Without the arr.ind parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".

> which( !is.na(p) )
[1]  6 11 17 24 32

just this ?

Do a git status to find out if your file is actually in your index or the commit.

It is easy as a beginner to misunderstand the index/staging area.

I view it as a 'progress pinboard'. I therefore have to add the file to the pinboard before I can commit it (i.e. a copy of the complete pinboard), I have to update the pinboard when required, and I also have to deliberately remove files from it when I've finished with them - simply creating, editing or deleting a file doesn't affect the pinboard. It's like 'storyboarding'.

Edit: As others noted, You should do the edits locally and then push the updated repo, rather than attempt to edit directly on github.

You can use the mounted() Vue Lifecycle Hook. This will allow you to call a method before the page loads.

This is an implementation example:

HTML:

<div id="app">
  <h1>Welcome our site {{ name }}</h1>
</div>

JS:

var app = new Vue ({
    el: '#app',
    data: {
        name: ''
    },
    mounted: function() {
        this.askName() // Calls the method before page loads
    },
    methods: {
        // Declares the method
        askName: function(){
            this.name = prompt(`What's your name?`)
        }
    }
})

This will get the prompt method's value, insert it in the variable name and output in the DOM after the page loads. You can check the code sample here.

You can read more about Lifecycle Hooks here.

Well, to start with List<T> does have the FindAll and ConvertAll methods - but the more idiomatic, modern approach is to use LINQ:

// Find all the people older than 30
var query1 = list.Where(person => person.Age > 30);

// Find each person's name
var query2 = list.Select(person => person.Name);

You'll need a using directive in your file to make this work:

using System.Linq;

Note that these don't use strings to express predicates and projects - they use delegates, usually created from lambda expressions as above.

If lambda expressions and LINQ are new to you, I would suggest you get a book covering LINQ first, such as LINQ in Action, Pro LINQ, C# 4 in a Nutshell or my own C# in Depth. You certainly can learn LINQ just from web tutorials, but I think it's such an important technology, it's worth taking the time to learn it thoroughly.

Something a bit more universal since this comes up on google. While the details are more specific, the title of this question is more universal.

/** 
 * recursively create a long directory path
 */
function createPath($path) {
    if (is_dir($path)) return true;
    $prev_path = substr($path, 0, strrpos($path, '/', -2) + 1 );
    $return = createPath($prev_path);
    return ($return && is_writable($prev_path)) ? mkdir($path) : false;
}

This will take a path, possibly with a long chain of uncreated directories, and keep going up one directory until it gets to an existing directory. Then it will attempt to create the next directory in that directory, and continue till it's created all the directories. It returns true if successful.

Could be improved by providing a stopping level so it just fails if it goes beyond user folder or something and by including permissions.

In any web application, there will be a web.xml in the WEB-INF/ folder.

If you dont have one in your web app, as it seems to be the case in your folder structure, the default Tomcat web.xml is under TOMCAT_HOME/conf/web.xml

Either way, the relevant lines of the web.xml are

<welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

so any file matching this pattern when found will be shown as the home page.

In Tomcat, a web.xml setting within your web app will override the default, if present.

I found a similar post @Autowired bean is null when referenced in the constructor of another bean .

The root cause of the error can be explained in the Spring reference doc (Autowired) , as follow:

Autowired Fields

Fields are injected right after construction of a bean, before any config methods are invoked.

But the real reason behind this statement in Spring doc is the Lifecycle of Bean in Spring. This is part of Spring's design philosophy.

This is Spring Bean Lifecycle Overview: Bean needs to be initialized first before it can be injected with properties such as field. This is how beans are designed, so this is the real reason.

I don't think adb pull handles wildcards for multiple files. I ran into the same problem and did this by moving the files to a folder and then pulling the folder.

I found a link doing the same thing. Try following these steps.

How to copy selected files from Android with adb pull

Although Martijin's answer is prob best. Here is a more intuitive way to process large csv files for beginners. This allows you to process groups of rows, or chunks, at a time.

import pandas as pd
chunksize = 10 ** 8
for chunk in pd.read_csv(filename, chunksize=chunksize):
    process(chunk)

you can do this :

private void setRowNumber(DataGridView dgv)
{
    foreach (DataGridViewRow row in dgv.Rows)
    {
        row.HeaderCell.Value = row.Index + 1;
    }

    dgv.AutoResizeRowHeadersWidth(DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders);

}

If you want some space at left and right of input view, you can add some padding like

private fun showAlertWithTextInputLayout(context: Context) {
    val textInputLayout = TextInputLayout(context)
    textInputLayout.setPadding(
        resources.getDimensionPixelOffset(R.dimen.dp_19), // if you look at android alert_dialog.xml, you will see the message textview have margin 14dp and padding 5dp. This is the reason why I use 19 here
        0,
        resources.getDimensionPixelOffset(R.dimen.dp_19),
        0
    )
    val input = EditText(context)
    textInputLayout.hint = "Email"
    textInputLayout.addView(input)

    val alert = AlertDialog.Builder(context)
        .setTitle("Reset Password")
        .setView(textInputLayout)
        .setMessage("Please enter your email address")
        .setPositiveButton("Submit") { dialog, _ ->
            // do some thing with input.text
            dialog.cancel()
        }
        .setNegativeButton("Cancel") { dialog, _ ->
            dialog.cancel()
        }.create()

    alert.show()
}

dimens.xml

Hope it help

I got it resolved by adding the jars in tomcat lib directory.

From Python 3.0 changelog;

The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively.

From the Python 3 email documentation it can be seen that io.StringIO should be used instead:

from io import StringIO
from email.generator import Generator
fp = StringIO()
g = Generator(fp, mangle_from_=True, maxheaderlen=60)
g.flatten(msg)
text = fp.getvalue()

Reference: https://docs.python.org/3/library/io.html

Select-Object creates a new psobject and copies the properties you requested to it. You can verify this with GetType():

PS > $a.GetType().fullname
System.DayOfWeek

PS > $b.GetType().fullname
System.Management.Automation.PSCustomObject

EDIT: Okay, so you don't want your local time (which isn't Australia) to contribute to the result, but instead the Australian time zone. Your existing code should be absolutely fine then, although Sydney is currently UTC+11, not UTC+10.. Short but complete test app:

import java.util.*;
import java.text.*;

public class Test {
    public static void main(String[] args) throws InterruptedException {
        Date date = new Date(1318386508000L);
        DateFormat format = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
        format.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));
        String formatted = format.format(date);
        System.out.println(formatted);
        format.setTimeZone(TimeZone.getTimeZone("Australia/Sydney"));
        formatted = format.format(date);
        System.out.println(formatted);
    }
}

Output:

12/10/2011 02:28:28
12/10/2011 13:28:28

I would also suggest you start using Joda Time which is simply a much nicer date/time API...

EDIT: Note that if your system doesn't know about the Australia/Sydney time zone, it would show UTC. For example, if I change the code about to use TimeZone.getTimeZone("blah/blah") it will show the UTC value twice. I suggest you print TimeZone.getTimeZone("Australia/Sydney").getDisplayName() and see what it says... and check your code for typos too :)

Man, I had the issue in one of my eclipse projects, amazingly the issue was the order of the jars in my .project file. believe it or not!

Close iis express and all the browsers (if the url was opened in any of the browser). Also open the visual studio IDE in admin mode. This has resolved my issue.

If I understand correctly, what you want to do is divide by the maximum value in each column. You can do this easily using broadcasting.

Starting with your example array:

import numpy as np

x = np.array([[1000,  10,   0.5],
              [ 765,   5,  0.35],
              [ 800,   7,  0.09]])

x_normed = x / x.max(axis=0)

print(x_normed)
# [[ 1.     1.     1.   ]
#  [ 0.765  0.5    0.7  ]
#  [ 0.8    0.7    0.18 ]]

x.max(0) takes the maximum over the 0th dimension (i.e. rows). This gives you a vector of size (ncols,) containing the maximum value in each column. You can then divide x by this vector in order to normalize your values such that the maximum value in each column will be scaled to 1.

If x contains negative values you would need to subtract the minimum first:

x_normed = (x - x.min(0)) / x.ptp(0)

Here, x.ptp(0) returns the "peak-to-peak" (i.e. the range, max - min) along axis 0. This normalization also guarantees that the minimum value in each column will be 0.

As of 13 December 2015

Whilst I found the accepted answer 100% correct, and useful, wished to expand upon it a little based on my own experiences, and hopefully for the benefit of others too. (Here I am using the terms package and module interchangeably)

In answer to the question, yes the accepted answer would be:

npm list -g --depth=0

You might wish to check for a particular module installed globally, on *nix systems / when grep available. This is particularly useful when checking what version of a module you are using (globally installed, just remove the -g flag if checking a local module):

npm list -g --depth=0 | grep <module_name>

If you'd like to see all available (remote) versions for a particular module, then do:

npm view <module_name> versions

Note, versions is plural. This will give you the full listing of versions to choose from.

For latest remote version:

npm view <module_name> version  

Note, version is singular.

To find out which packages need to be updated, you can use

npm outdated -g --depth=0

To update global packages, you can use

npm update -g <package>

To update all global packages, you can use:

npm update -g

(However, for npm versions less than 2.6.1, please also see this link as there is a special script that is recommended for globally updating all packages).

The above commands should work across NPM versions 1.3.x, 1.4.x, 2.x and 3.x

Made up example

Imagine that you want to create the following sequence: 1, 2, 2, 3, 3, 3, 4, 4, 4, 4 etc. (in other words: 1x1, 2x2, 3x3 etc.)

With flatMap it could look like:

IntStream sequence = IntStream.rangeClosed(1, 4)
                          .flatMap(i -> IntStream.iterate(i, identity()).limit(i));
sequence.forEach(System.out::println);

where:

• IntStream.rangeClosed(1, 4) creates a stream of int from 1 to 4, inclusive
• IntStream.iterate(i, identity()).limit(i) creates a stream of length i of int i - so applied to i = 4 it creates a stream: 4, 4, 4, 4
• flatMap "flattens" the stream and "concatenates" it to the original stream

With Java < 8 you would need two nested loops:

List<Integer> list = new ArrayList<>();
for (int i = 1; i <= 4; i++) {
    for (int j = 0; j < i; j++) {
        list.add(i);
    }
}

Real world example

Let's say I have a List<TimeSeries> where each TimeSeries is essentially a Map<LocalDate, Double>. I want to get a list of all dates for which at least one of the time series has a value. flatMap to the rescue:

list.stream().parallel()
    .flatMap(ts -> ts.dates().stream()) // for each TS, stream dates and flatmap
    .distinct()                         // remove duplicates
    .sorted()                           // sort ascending
    .collect(toList());

Not only is it readable, but if you suddenly need to process 100k elements, simply adding parallel() will improve performance without you writing any concurrent code.

To connect from the localhost you need to add '--net host':

docker run --name some-postgres --net host -e POSTGRES_PASSWORD=mysecretpassword -d -p 5432:5432 postgres

You can access the server directly without using exec from your localhost, by using:

psql -h localhost -p 5432 -U postgres

Use combobox and add the following css .ddTitleText{ display : none; }

No more text, just images.

I had the same issue when I used a DockerFile. My Docker is based on the php:5.5-apache image.

I got that error when executing the command "RUN docker-php-ext-install soap"

I have solved it by adding the following command to my DockerFile

"RUN apt-get update && apt-get install -y libxml2-dev"

The size of the months of the year and the way that Leap Years work fits perfectly into keeping our time on track with the sun.

Our current system of leap years has been in effect since February 24th, 1582, and will likely stay in effect for the foreseeable future.

DST, however, is very subject to change. It may be that 20 years from now, some country may offset time by a whole day or some other extreme for DST. A whole DST day will almost certainly never happen, but DST is still nevertheless very up-in-the-air and indecisive. Thus, the above solution is future proof in addition to being very very fast.

The above code snippet runs very fast. My computer can process 65536 dates in ~52ms on Chrome.

Just one command did the work

netsh http add iplisten 127.0.0.1

I have incorporated this (with little to no modification) into a UWP DataBinding Converter for my project and thought it might also be useful to others.

The code is:

using System;
using System.Text;
using Windows.UI.Xaml.Data;

namespace MyApp.Converters
{
    public class ByteSizeConverter : IValueConverter
    {
        static readonly string[] sSizeSuffixes = { "bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB" };

        // The number of decimal places the formatter should include in the scaled output - default 1dp
        public int DecimalPlaces { get; set; } = 1;

        public object Convert(object value, Type targetType, object parameter, string language)
        {
            Int64 intVal = System.Convert.ToInt64(value);

            return SizeSuffix(intVal);
        }

        public object ConvertBack(object value, Type targetType, object parameter, string language)
        {
            // TODO: Parse string into number and suffix
            //       Scale number by suffix multiplier to get bytes
            throw new NotImplementedException();
        }

        string SizeSuffix(Int64 value)
        {
            if (this.DecimalPlaces < 0) { throw new ArgumentOutOfRangeException(String.Format("DecimalPlaces = {0}", this.DecimalPlaces)); }
            if (value < 0) { return "-" + SizeSuffix(-value); }
            if (value == 0) { return string.Format("{0:n" + this.DecimalPlaces + "} bytes", 0); }

            // magnitude is 0 for bytes, 1 for KB, 2, for MB, etc.
            int magnitude = (int)Math.Log(value, 1024);
            // clip magnitude - only 8 values currently supported, this prevents out-of-bounds exception
            magnitude = Math.Min(magnitude, 8);

            // 1L << (magnitude * 10) == 2 ^ (10 * magnitude) [i.e. the number of bytes in the unit corresponding to magnitude]
            decimal adjustedSize = (decimal)value / (1L << (magnitude * 10));

            // make adjustment when the value is large enough that it would round up to 1000 or more
            if (Math.Round(adjustedSize, this.DecimalPlaces) >= 1000)
            {
                magnitude += 1;
                adjustedSize /= 1024;
            }

            return String.Format("{0:n" + this.DecimalPlaces + "} {1}", adjustedSize, sSizeSuffixes[magnitude]);
        }
    }
}

To use it, add a local resource to your UserControl or Page XAML:

<UserControl.Resources>
    <converters:ByteSizeConverter x:Key="ByteFormat" DecimalPlaces="3" />
</UserControl.Resources>

Reference it in a data binding template or data binding instance:

<TextBlock HorizontalAlignment="Left" VerticalAlignment="Center"
    Text="{x:Bind MyItem.FileSize_bytes, Mode=OneWay, Converter={StaticResource ByteFormat}}" />

And hey presto. The magic happens.

the name of the the test case for class Foo should be FooTestCase or something like it (FooIntegrationTestCase or FooAcceptanceTestCase) - since it is a test case. see http://xunitpatterns.com/ for some standard naming conventions like test, test case, test fixture, test method, etc.

Add any other allowable non-alphanumeric characters to the middle brackets to allow them to be parsed as well.

You can't truly do it in "standard" C, because the size of an int and of a char aren't fixed. Let's say you are using a compiler under Windows or Linux on an intel PC...

int i = 5;
char a = ((char*)&i)[0];
char b = ((char*)&i)[1];

Remember of endianness of your machine! And that int are "normally" 32 bits, so 4 chars!

But you probably meant "i want to stringify a number", so ignore this response :-)

Logic index:

d<-d[!(d$A=="B" & d$E==0),]

It means you haven't assigned a provisioning profile to the configuration.

Usually it's because "Any iOS SDK" must have a profile and cannot be set to "Don't sign".

All this and more is answered in the TN2250 Tech Note about Code Signing and Troubleshooting.

The best way to set/get the value of a textarea is the .val(), .value method.

.text() internally uses the .textContent (or .innerText for IE) method to get the contents of a <textarea>. The following test cases illustrate how text() and .val() relate to each other:

var t = '<textarea>';
console.log($(t).text('test').val());             // Prints test
console.log($(t).val('too').text('test').val());  // Prints too
console.log($(t).val('too').text());              // Prints nothing
console.log($(t).text('test').val('too').val());  // Prints too

console.log($(t).text('test').val('too').text()); // Prints test

The value property, used by .val() always shows the current visible value, whereas text()'s return value can be wrong.

and if you don't have the option to go on java8 better use 'yyyy-MM-dd'T'HH:mm:ssXXX' as this gets correctly parsed again (while with only one X this may not be the case... depending on your parsing function)

X generates: +01

XXX generates: +01:00

I was solving this leetcode problem and I came across this beautiful solution by a user named Zitao Wang.

The problem goes like this for each element in the given array find the product of all the remaining numbers without making use of divison and in O(n) time

The standard solution is:

Pass 1: For all elements compute product of all the elements to the left of it
Pass 2: For all elements compute product of all the elements to the right of it
        and then multiplying them for the final answer 

His solution uses only one for loop by making use of. He computes the left product and right product on the fly using ~

def productExceptSelf(self, nums):
    res = [1]*len(nums)
    lprod = 1
    rprod = 1
    for i in range(len(nums)):
        res[i] *= lprod
        lprod *= nums[i]
        res[~i] *= rprod
        rprod *= nums[~i]
    return res

Instead of using a %, the units vh set it to a percent of the viewport (browser window) size.

I was able to set a modal with an image and text beneath to be responsive to the browser window size using vh.

If you just want the content to scroll, you could leave out the part that limits the size of the modal body.

/*When the modal fills the screen it has an even 2.5% on top and bottom*/
/*Centers the modal*/
.modal-dialog {
  margin: 2.5vh auto;
}

/*Sets the maximum height of the entire modal to 95% of the screen height*/
.modal-content {
  max-height: 95vh;
  overflow: scroll;
}

/*Sets the maximum height of the modal body to 90% of the screen height*/
.modal-body {
  max-height: 90vh;
}
/*Sets the maximum height of the modal image to 69% of the screen height*/
.modal-body img {
  max-height: 69vh;
}

Guys remember that you can use the try catch end event

Dim Green as integer

Try
    Green = InputBox("Please enter a value for green")
    Catch ex as Exception
        MsgBox("Green must be a valid integer!")
End Try

Swift 5 : If you continuously want input from keyboard , without ending the program, like a stream of input, Use below steps:

1. Create new project of type comnnad line tool

   2. Add below code in main.swift file:

      var inputArray = [String]()
      
      while let input = readLine() {
      
      guard input != "quit" else {
      
      break
      
      }
      
      inputArray.append(input)
      
      print("You entered: \(input)")
      
      print(inputArray)
      
      print("Enter a word:")
      }   
      

   3. RunThe project and click the executable under Products folder in Xcode and open in finder
   4. Double click the executable to open it.
   5. Now enter your Inputs. Terminal will look something like this:

I found that the only option that worked for me was

font-size:0;

I was also using overflow and white-space: nowrap; float: left; seems to mess things up

Behe's answer with sorting plugins did not work on my Jenkins machine. I received the error java.lang.UnsupportedOperationException due to trying to sort an immutable collection i.e. Jenkins.instance.pluginManager.plugins. Simple fix for the code:

List<String> jenkinsPlugins = new ArrayList<String>(Jenkins.instance.pluginManager.plugins);
jenkinsPlugins.sort { it.displayName }
              .each { plugin ->
                   println ("${plugin.shortName}:${plugin.version}")
              }

Use the http://<jenkins-url>/script URL to run the code.

You can get the name value from an input field using name element in jQuery by:

var firstname = jQuery("#form1 input[name=firstname]").val(); //Returns ABCD_x000D_
var lastname = jQuery("#form1 input[name=lastname]").val(); //Returns XYZ _x000D_
console.log(firstname);_x000D_
console.log(lastname);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<form name="form1" id="form1">_x000D_
  <input type="text" name="firstname" value="ABCD"/>_x000D_
  <input type="text" name="lastname" value="XYZ"/>_x000D_
</form>

This link on MSDN is worth a visit: How to: Implement CopyToDataTable<T> Where the Generic Type T Is Not a DataRow

This adds an extension method that lets you do this:

// Create a sequence. 
Item[] items = new Item[] 
{ new Book{Id = 1, Price = 13.50, Genre = "Comedy", Author = "Gustavo Achong"}, 
  new Book{Id = 2, Price = 8.50, Genre = "Drama", Author = "Jessie Zeng"},
  new Movie{Id = 1, Price = 22.99, Genre = "Comedy", Director = "Marissa Barnes"},
  new Movie{Id = 1, Price = 13.40, Genre = "Action", Director = "Emmanuel Fernandez"}};

// Query for items with price greater than 9.99.
var query = from i in items
             where i.Price > 9.99
             orderby i.Price
             select i;

// Load the query results into new DataTable.
DataTable table = query.CopyToDataTable();

Here is a simple way (to use before or after pseudo elements / classes):

input[type=checkbox] {
    position: relative;
}

input[type=checkbox]:after {
    position: absolute;
    top: 0;
    left: 0;
    /* Above three lines allow the checkbox:after position at checkbox's position */
    content: '';
    width: 32px;
    height: 32px;
    z-index: 1; /* This allows the after overlap the checkbox */
    /* Anything you want */
}

If you want first 2 letters and last 2 letters of a string then you can use the following code: name = "India" name[0:2]="In" names[-2:]="ia"

Another way, which is a little bit easier for me is to use named pipes. Named pipes provided a way to synchronize and sending messages between different processes.

A.bash:

#!/bin/bash
msg="The Message"
echo $msg > A.pipe

B.bash:

#!/bin/bash
msg=`cat ./A.pipe`
echo "message from A : $msg"

Usage:

$ mkfifo A.pipe #You have to create it once
$ ./A.bash & ./B.bash # you have to run your scripts at the same time

B.bash will wait for message and as soon as A.bash sends the message, B.bash will continue its work.

Yo could also set labels = FALSE inside axis(...) and print the labels in a separate command with Text. With this option you can rotate the text the text in case you need it

lablist<-as.vector(c(1:10))
axis(1, at=seq(1, 10, by=1), labels = FALSE)
text(seq(1, 10, by=1), par("usr")[3] - 0.2, labels = lablist, srt = 45, pos = 1, xpd = TRUE)

Detailed explanation here

The other solutions didn't work for me. Maybe the old DOCTYPE in the project I am working on prevents HTML5 options.

My solution:

<form id="form_1" action="result.php" method="post"
 onsubmit="sendForm(this.id);return false">
    <input type="hidden" name="something" value="1">
</form>

js:

function sendForm(form_id){
    var form = $('#'+form_id);
    $.ajax({
        type: 'POST',
        url: $(form).attr('action'),
        data: $(form).serialize(),
        success: function(result) {
            console.log(result)
        }
    });
}

Using the latest cross-platform Google Maps URLs: Even if google maps app is missing it will open in browser

Example https://www.google.com/maps/dir/?api=1&origin=81.23444,67.0000&destination=80.252059,13.060604

Uri.Builder builder = new Uri.Builder();
builder.scheme("https")
    .authority("www.google.com")
    .appendPath("maps")
    .appendPath("dir")
    .appendPath("")
    .appendQueryParameter("api", "1")
    .appendQueryParameter("destination", 80.00023 + "," + 13.0783);
String url = builder.build().toString();
Log.d("Directions", url);
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);

Please refer to this for the example .The main point is to use the groupProperty() , and the related aggregate functions provided by the Projections class.

For example :

SELECT column_name, max(column_name) , min (column_name) , count(column_name)
FROM table_name
WHERE column_name > xxxxx
GROUP BY column_name

Its equivalent criteria object is :

List result = session.createCriteria(SomeTable.class)       
                    .add(Restrictions.ge("someColumn", xxxxx))      
                    .setProjection(Projections.projectionList()
                            .add(Projections.groupProperty("someColumn"))
                            .add(Projections.max("someColumn"))
                            .add(Projections.min("someColumn"))
                            .add(Projections.count("someColumn"))           
                    ).list();

Tested with PyCharm 4.0.6 (OSX 10.10.3) following this steps:

1. Click PyCharm menu.
2. Select Project Interpreter.
3. Select Gear icon.
4. Select More button.
5. Select Project Interpreter you are in.
6. Select Directory Tree button.
7. Select Reload list of paths.

Problem solved!

If you update a submodule and commit to it, you need to go to the containing, or higher level repo and add the change there.

git status

will show something like:

modified:
   some/path/to/your/submodule

The fact that the submodule is out of sync can also be seen with

git submodule

the output will show:

+afafaffa232452362634243523 some/path/to/your/submodule

The plus indicates that the your submodule is pointing ahead of where the top repo expects it to point to.

simply add this change:

git add some/path/to/your/submodule

and commit it:

git commit -m "referenced newer version of my submodule"

When you push up your changes, make sure you push up the change in the submodule first and then push the reference change in the outer repo. This way people that update will always be able to successfully run

git submodule update

More info on submodules can be found here http://progit.org/book/ch6-6.html.

If we need to move from one component to another service then we have to define that service into app.module providers array.

Sources telling you to use apstring.h are materials for the Advanced Placement course in computer science. It describes a string class that you'll use through the course, and some of the exam questions may refer to it and expect you to be moderately familiar with it. Unless you're enrolled in that class or studying to take that exam, ignore those sources.

Sources telling you to use string.h are either not really talking about C++, or are severely outdated. You should probably ignore them, too. That header is for the C functions for manipulating null-terminated arrays of characters, also known as C-style strings.

In C++, you should use the string header. Write #include <string> at the top of your file. When you declare a variable, the type is string, and it's in the std namespace, so its full name is std::string. You can avoid having to write the namespace portion of that name all the time by following the example of lots of introductory texts and saying using namespace std at the top of the C++ source files (but generally not at the top of any header files you might write).

Please refer SysInternal toolkit from Microsoft from below link, https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

You're missing quotes around your string:

I use the way shown below. It submits everything like files.

$(document).on("submit", "form", function(event)
{
    event.preventDefault();

    var url  = $(this).attr("action");
    $.ajax({
        url: url,
        type: 'POST',
        dataType: "JSON",
        data: new FormData(this),
        processData: false,
        contentType: false,
        success: function (data, status)
        {

        },
        error: function (xhr, desc, err)
        {
            console.log("error");
        }
    });
});

Not sure if this is still extant but I'm guessing you need something like

((field Like "AA*") AND (field Not Like "BB*"))

IF exists

IF exists (select * from table_1 where col1 = 'value')
BEGIN
    -- one or more
    insert into table_1 (col1) values ('valueB')
END
ELSE
    -- zero
    insert into table_1 (col1) values ('value') 

As per http://content-security-policy.com/ The best place to start:

    default-src 'none'; 
    script-src 'self'; 
    connect-src 'self'; 
    img-src 'self'; 
    style-src 'self';
    font-src 'self';

Never inline styles or scripts as it undermines the purpose of CSP. You can use a stylesheet to set a style property and then use a function in a .js file to change the style property (if need be).

TL;DR To fix this issue, invoke packaging plugin before, e.g. for jar packaging use maven-jar-plugin , as following:

mvn jar:jar install:install

Or

mvn jar:jar deploy:deploy 

If you actually needed to deploy.

Gotcha This approach won't work if you have multi-module project with different packagings (ear/war/jar/zip) – even worse, wrong artifacts will be installed/deployed! In such case use reactor options to only build the deployable module (e.g. the war).

Explanation

In some cases you actually want to run directly a install:install or deploy:deploy goal (that is, from the maven-deploy-plugin, the deploy goal, not the Maven deploy phase) and you would end up in the annoying The packaging for this project did not assign a file to the build artifact.

A classic example is a CI job (a Jenkins or Bamboo job, e.g.) where in different steps you want to execute/care about different aspects:

• A first step would be a mvn clean install, performing tests and test coverage
• A second step would be a Sonarqube analysis based on a quality profile, e.g. mvn sonar:sonar plus further options
• Then, and only after successful tests execution and quality gate passed, you want to deploy to your Maven enterprise repository the final project artifacts, yet you don't want to re-run mvn deploy, because it would again execute previous phases (and compile, test, etc.) and you want your build to be effective but yet fast.

Yes, you could speed up this last step at least skipping tests (compilation and execution, via -Dmaven.test.skip=true) or play with a particular profile (to skip as many plugins as possible), but it is much easier and clear to simply run mvn deploy:deploy then.

But it would fail with the error above, because as also specified by the plugin FAQ:

During the packaging-phase all gathered and placed in context. With this mechanism Maven can ensure that the maven-install-plugin and maven-deploy-plugin are copying/uploading the same set of files. So when you only execute deploy:deploy, then there are no files put in the context and there is nothing to deploy.

Indeed, the deploy:deploy needs some runtime information placed in the build context by previous phases (or previous plugins/goals executions).

It has also reported as a potential bug: MDEPLOY-158: deploy:deploy does not work for only Deploying artifact to Maven Remote repo

But then rejected as not a problem.

The deployAtEnd configuration option of the maven-deploy-plugin won't help neither in certain scenarios because we have intermediate job steps to execute:

Whether every project should be deployed during its own deploy-phase or at the end of the multimodule build. If set to true and the build fails, none of the reactor projects is deployed. (experimental)

So, how to fix it?
Simply run the following in such a similar third/last step:

mvn jar:jar deploy:deploy

The maven-jar-plugin will not re-create any jar as part of your build, thanks to its forceCreation option set to false by default:

Require the jar plugin to build a new JAR even if none of the contents appear to have changed. By default, this plugin looks to see if the output jar exists and inputs have not changed. If these conditions are true, the plugin skips creation of the jar.

But it will nicely populate the build context for us and make deploy:deploy happy. No tests to skip, no profiles to add. Just what you need: speed.

Additional note: if you are using the build-helper-maven-plugin, buildnumber-maven-plugin or any other similar plugin to generate meta-data later on used by the maven-jar-plugin (e.g. entries for the Manifest file), you most probably have executions linked to the validate phase and you still want to have them during the jar:jar build step (and yet keep a fast execution). In this case the almost harmless overhead is to invoke the validate phase as following:

mvn validate jar:jar deploy:deploy

Yet another additional note: if you have not jar but, say, war packaging, use war:war before install/deploy instead.

Gotcha as pointed out above, check behavior in multi module projects.

Don't roll your own, use these handy (and extensible) wrappers provided by Microsoft.

For example:

#include <msclr\marshal_cppstd.h>

System::String^ managed = "test";
std::string unmanaged = msclr::interop::marshal_as<std::string>(managed);

Simple Get Request using HttpClient Class

using System.Net.Http;

   static void Main(string[] args)
    {
        HttpClient httpClient = new HttpClient();
        var result = httpClient.GetAsync("https://www.google.com").Result;
    }

}

I favor field accessors. The code is much cleaner. All the annotations can be placed in one section of a class and the code is much easier to read.

I found another problem with property accessors: if you have getXYZ methods on your class that are NOT annotated as being associated with persistent properties, hibernate generates sql to attempt to get those properties, resulting in some very confusing error messages. Two hours wasted. I did not write this code; I have always used field accessors in the past and have never run into this issue.

Here are the steps solved for me (For those who face the same problem in XCode 9.2):

1. Just manually deleted local profiles in ~/Library/MobileDevice/Provisioning Profiles.

2. Deleted and created all the certificates and provisioning profile from developers account.

3. Removed developers account from Xcode and re-added it.

Solved my problem! :-)

I also had this problem. it was weird that it worked on my lollipop emulator, but not on my actual kitkat device.

Android Studio will now force you to write the permission upper case, and that's the problem.

Add

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Above the application tab and it will work.

Pre-append your commands with sudo.

For example, Instead of vim textfile.txt, used sudo vim textfile.txt. This will resolve the issue.

Print the last json error when debugging.

json_decode( $so, true, 9 );
$json_errors = array(
    JSON_ERROR_NONE => 'No error has occurred',
    JSON_ERROR_DEPTH => 'The maximum stack depth has been exceeded',
    JSON_ERROR_CTRL_CHAR => 'Control character error, possibly incorrectly encoded',
    JSON_ERROR_SYNTAX => 'Syntax error',
);
 echo 'Last error : ', $json_errors[json_last_error()], PHP_EOL, PHP_EOL;

I suspect it's just following the Linux / Unix standard for returning 0 on success.

Does it really say "1" is false and "0" is true?

When passing a struct to another function, it would usually be better to do as Donnell suggested above and pass it by reference instead.

A very good reason for this is that it makes things easier if you want to make changes that will be reflected when you return to the function that created the instance of it.

Here is an example of the simplest way to do this:

#include <stdio.h>

typedef struct student {
    int age;
} student;

void addStudent(student *s) {
    /* Here we can use the arrow operator (->) to dereference 
       the pointer and access any of it's members: */
    s->age = 10;
}

int main(void) {

    student aStudent = {0};     /* create an instance of the student struct */
    addStudent(&aStudent);      /* pass a pointer to the instance */

    printf("%d", aStudent.age);

    return 0;
}

In this example, the argument for the addStudent() function is a pointer to an instance of a student struct - student *s. In main(), we create an instance of the student struct and then pass a reference to it to our addStudent() function using the reference operator (&).

In the addStudent() function we can make use of the arrow operator (->) to dereference the pointer, and access any of it's members (functionally equivalent to: (*s).age).

Any changes that we make in the addStudent() function will be reflected when we return to main(), because the pointer gave us a reference to where in the memory the instance of the student struct is being stored. This is illustrated by the printf(), which will output "10" in this example.

Had you not passed a reference, you would actually be working with a copy of the struct you passed in to the function, meaning that any changes would not be reflected when you return to main - unless you implemented a way of passing the new version of the struct back to main or something along those lines!

Although pointers may seem off-putting at first, once you get your head around how they work and why they are so handy they become second nature, and you wonder how you ever coped without them!

This error can also happen if you have circular dependencies. Check your imports and make sure you do not have any cycles.

Here's how to do it with the basic file operations in Python. This opens one file, reads the data into memory, then opens the second file and writes it out.

in_file = open("in-file", "rb") # opening for [r]eading as [b]inary
data = in_file.read() # if you only wanted to read 512 bytes, do .read(512)
in_file.close()

out_file = open("out-file", "wb") # open for [w]riting as [b]inary
out_file.write(data)
out_file.close()

We can do this more succinctly by using the with keyboard to handle closing the file.

with open("in-file", "rb") as in_file, open("out-file", "wb") as out_file:
    out_file.write(in_file.read())

If you don't want to store the entire file in memory, you can transfer it in pieces.

piece_size = 4096 # 4 KiB

with open("in-file", "rb") as in_file, open("out-file", "wb") as out_file:
    while True:
        piece = in_file.read(piece_size)

        if piece == "":
            break # end of file

        out_file.write(piece)

Something like this should work:

UPDATE
    table_Name
SET 
  column_A = CASE WHEN @flag = '1' THEN column_A + @new_value ELSE column_A END,
  column_B = CASE WHEN @flag = '0' THEN column_B + @new_value ELSE column_B END
WHERE
    ID = @ID

The first parameter to concatenate should itself be a sequence of arrays to concatenate:

numpy.concatenate((a,b)) # Note the extra parentheses.

wget --spider -S "http://url/to/be/checked" 2>&1 | grep "HTTP/" | awk '{print $2}'

prints only the status code for you

To answer a more generic case, this error is noticed when you pick a function name which is already used in some built in library. For e.g., select.

A simple method to know about it is while compiling the file, the compiler will indicate the previous declaration.

Check this page out: http://matplotlib.org/examples/pylab_examples/subplots_demo.html

plt.subplots is similar. I think it's better since it's easier to set parameters of the figure. The first two arguments define the layout (in your case 1 row, 2 columns), and other parameters change features such as figure size:

import numpy as np
import matplotlib.pyplot as plt

x1 = np.linspace(0.0, 5.0)
x2 = np.linspace(0.0, 2.0)
y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
y2 = np.cos(2 * np.pi * x2)

fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(5, 3))
axes[0].plot(x1, y1)
axes[1].plot(x2, y2)
fig.tight_layout()

Here's yet another way (using a negative look-ahead):

^/(?!ignoreme|ignoreme2|ignoremeN)([a-z0-9]+)$ 

Note: There's only one capturing expression: ([a-z0-9]+).

np.where returns a tuple of length equal to the dimension of the numpy ndarray on which it is called (in other words ndim) and each item of tuple is a numpy ndarray of indices of all those values in the initial ndarray for which the condition is True. (Please don't confuse dimension with shape)

For example:

x=np.arange(9).reshape(3,3)
print(x)
array([[0, 1, 2],
      [3, 4, 5],
      [6, 7, 8]])
y = np.where(x>4)
print(y)
array([1, 2, 2, 2], dtype=int64), array([2, 0, 1, 2], dtype=int64))

y is a tuple of length 2 because x.ndim is 2. The 1st item in tuple contains row numbers of all elements greater than 4 and the 2nd item contains column numbers of all items greater than 4. As you can see, [1,2,2,2] corresponds to row numbers of 5,6,7,8 and [2,0,1,2] corresponds to column numbers of 5,6,7,8 Note that the ndarray is traversed along first dimension(row-wise).

Similarly,

x=np.arange(27).reshape(3,3,3)
np.where(x>4)

will return a tuple of length 3 because x has 3 dimensions.

But wait, there's more to np.where!

when two additional arguments are added to np.where; it will do a replace operation for all those pairwise row-column combinations which are obtained by the above tuple.

x=np.arange(9).reshape(3,3)
y = np.where(x>4, 1, 0)
print(y)
array([[0, 0, 0],
   [0, 0, 1],
   [1, 1, 1]])

This issue can happen not only in eclipse but also in any of the text-editor.

On windows systems, windows-10 in my case, this issue arose when the shift and insert key was pressed in tandem unintentionally which takes the user to the overwrite mode.

To get back to insert mode you need to press shift and insert in tandem again.

npm uninstall

npm cache clean --force

I tried these two methods but they didn't work. After, I deleted the node_modules directory and ran npm install again, it still didn't work. Lastly, I deleted package-lock.json and created a new package-lock.json file using

npm install

There is something wrong with the accepted answer, it sometimes (randomly) brings a clipped response from server. I do not know why, I did not investigate the faulty cause of the accepted answer because this code worked perfectly for me:

import paramiko

ip='server ip'
port=22
username='username'
password='password'

cmd='some useful command' 

ssh=paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(ip,port,username,password)

stdin,stdout,stderr=ssh.exec_command(cmd)
outlines=stdout.readlines()
resp=''.join(outlines)
print(resp)

stdin,stdout,stderr=ssh.exec_command('some really useful command')
outlines=stdout.readlines()
resp=''.join(outlines)
print(resp)

Where do you want to see the output?

Messages being output via Debug.Print will be displayed in the immediate window which you can open by pressing Ctrl+G.

You can also Activate the so called Immediate Window by clicking View -> Immediate Window on the VBE toolbar

You're not far; you need to do something like this:

[WebMethod]
public static string GetProducts()
{
  // instantiate a serializer
  JavaScriptSerializer TheSerializer = new JavaScriptSerializer();

  //optional: you can create your own custom converter
  TheSerializer.RegisterConverters(new JavaScriptConverter[] {new MyCustomJson()});

  var products = context.GetProducts().ToList();   

  var TheJson = TheSerializer.Serialize(products);

  return TheJson;
}

You can reduce this code further but I left it like that for clarity. In fact, you could even write this:

return context.GetProducts().ToList();

and this would return a json string. I prefer to be more explicit because I use custom converters. There's also Json.net but the framework's JavaScriptSerializer works just fine out of the box.

Extending @Ryogi answer above, you can take advantage of the lower.tail parameter like so:

qt(0.25/2, 40, lower.tail = FALSE) # 75% confidence

qt(0.01/2, 40, lower.tail = FALSE) # 99% confidence

This is common issue only. Even I have faced this issue. On the development machine, configured with Windows authentication, it is worked perfectly:

<add name="ShoppingCartAdminEntities" connectionString="metadata=res://*/ShoppingCartAPIModel.csdl|res://*/ShoppingCartAPIModel.ssdl|res://*/ShoppingCartAPIModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=.\SQlExpress;initial catalog=ShoppingCartAdmin;Integrated Security=True;multipleactiveresultsets=True;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" />

Once hosted in IIS with the same configuration, I got this error:

The underlying provider failed on Open

It was solved changing connectionString in the configuration file:

<add name="MyEntities" connectionString="metadata=res://*/ShoppingCartAPIModel.csdl|res://*/ShoppingCartAPIModel.ssdl|res://*/ShoppingCartAPIModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=MACHINE_Name\SQlExpress;initial catalog=ShoppingCartAdmin;persist security info=True;user id=sa;password=notmyrealpassword;multipleactiveresultsets=True;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" />

Other common mistakes could be:

1. Database service could be stopped
2. Data Source attributes pointing to a local database with Windows authentication and hosted in IIS
3. Username and password could be wrong.

var Request = {
    List: [],
    AbortAll: function () {
        var _self = this;
        $.each(_self.List, (i, v) => {
            v.abort();
        });
    }
}
var settings = {
    "url": "http://localhost",
    success: function (resp) {
        console.log(resp)
    }
}

Request.List.push($.ajax(settings));

whenever you want to abort all the ajax request, you just need call this line

Request.AbortAll()

On Solaris, you can use the option -I to read the filenames that you would normally state on the command line from a file. In contrast to the command line, this can create tar archives with hundreds of thousands of files (just did that).

So the example would read

tar -cvf allfiles.tar -I mylist.txt

You can flip it around and list the dependencies in setup.py and have a single character — a dot . — in requirements.txt instead.

Alternatively, even if not advised, it is still possible to parse the requirements.txt file (if it doesn't refer any external requirements by URL) with the following hack (tested with pip 9.0.1):

install_reqs = parse_requirements('requirements.txt', session='hack')

This doesn't filter environment markers though.

In old versions of pip, more specifically older than 6.0, there is a public API that can be used to achieve this. A requirement file can contain comments (#) and can include some other files (--requirement or -r). Thus, if you really want to parse a requirements.txt you can use the pip parser:

from pip.req import parse_requirements

# parse_requirements() returns generator of pip.req.InstallRequirement objects
install_reqs = parse_requirements(<requirements_path>)

# reqs is a list of requirement
# e.g. ['django==1.5.1', 'mezzanine==1.4.6']
reqs = [str(ir.req) for ir in install_reqs]

setup(
    ...
    install_requires=reqs
)

I believe that you are looking for the java.lang.BigDecimal class.

Try this instead:

ping -c2 -s16 sntdn | awk '{print NR " | " strftime("%Y-%m-%d_%H:%M:%S") " | " $0  }'

Check if it suits you

I've used another API for this purpose..

var readline = require('readline');
var rl = readline.createInterface(process.stdin, process.stdout);
rl.setPrompt('guess> ');
rl.prompt();
rl.on('line', function(line) {
    if (line === "right") rl.close();
    rl.prompt();
}).on('close',function(){
    process.exit(0);
});

This allows to prompt in loop until the answer is right. Also it gives nice little console.You can find the details @ http://nodejs.org/api/readline.html#readline_example_tiny_cli

A function that can insert at both integer and string positions:

/**
 * @param array      $array
 * @param int|string $position
 * @param mixed      $insert
 */
function array_insert(&$array, $position, $insert)
{
    if (is_int($position)) {
        array_splice($array, $position, 0, $insert);
    } else {
        $pos   = array_search($position, array_keys($array));
        $array = array_merge(
            array_slice($array, 0, $pos),
            $insert,
            array_slice($array, $pos)
        );
    }
}

Integer usage:

$arr = ["one", "two", "three"];
array_insert(
    $arr,
    1,
    "one-half"
);
// ->
array (
  0 => 'one',
  1 => 'one-half',
  2 => 'two',
  3 => 'three',
)

String Usage:

$arr = [
    "name"  => [
        "type"      => "string",
        "maxlength" => "30",
    ],
    "email" => [
        "type"      => "email",
        "maxlength" => "150",
    ],
];

array_insert(
    $arr,
    "email",
    [
        "phone" => [
            "type"   => "string",
            "format" => "phone",
        ],
    ]
);
// ->

Official answer from fb team

In my case, migrating a Spring 3.1 app up to 3.2.7, my solution was similar to Matthias's but a bit different -- thus why I'm documenting it here:

In my POM I found this dependency and changed it from 6.0 to 7.0:

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-web-api</artifactId>
        <version>7.0</version>
        <scope>provided</scope>
    </dependency>

Then later in the POM I upgraded this plugin from 6.0 to 7.0:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>2.1</version>
            <executions>
                <execution>
                    ...
                    <configuration>
                        ...
                        <artifactItems>
                            <artifactItem>
                                <groupId>javax</groupId>
                                <artifactId>javaee-endorsed-api</artifactId>
                                <version>7.0</version>
                                <type>jar</type>
                            </artifactItem>
                        </artifactItems>
                    </configuration>
                </execution>
            </executions>
        </plugin>

When it gets to real world usage of these datatypes, it is very important that you understand that using certain integer types could just be an overkill or under used. For example, using integer datatype for employeeCount in a table say employee could be an overkill since it supports a range of integer values from ~ negative 2 billion to positive 2 billion or zero to approximately 4 billion (unsigned). So, even if you consider one of the US biggest employer such as Walmart with roughly about 2.2 million employees using an integer datatype for the employeeCount column would be unnecessary. In such a case you use mediumint (that supports from 0 to 16 million (unsigned)) for example. Having said that if your range is expected to be unusually large you might consider bigint which as you can see from Daniel's notes supports a range larger than I care to decipher.

Looking at the code always helps too. That is, you can actually take a look at the generated partial class (that calls LoadComponent) by doing the following:

1. Go to the Solution Explorer pane in the Visual Studio solution that you are interested in.
2. There is a button in the tool bar of the Solution Explorer titled 'Show All Files'. Toggle that button.
3. Now, expand the obj folder and then the Debug or Release folder (or whatever configuration you are building) and you will see a file titled YourClass.g.cs.

The YourClass.g.cs ... is the code for generated partial class. Again, if you open that up you can see the InitializeComponent method and how it calls LoadComponent ... and much more.

use substring function:

yourString.Substring(0, length);

Can't comment the last answer but the fix is relatively easy. Just set the background color of your opaque canvas:

#canvas1 { background-color: black; } //opaque canvas
#canvas2 { ... } //transparent canvas

I'm not sure but it looks like that the background-color is inherited as transparent from the body.

I couldn't find a neat way in the end so I went for create a directory called local_modules and then added this bashscript to the package.json in scripts->preinstall

#!/bin/sh
for i in $(find ./local_modules -type d -maxdepth 1) ; do
    packageJson="${i}/package.json"
    if [ -f "${packageJson}" ]; then
        echo "installing ${i}..."
        npm install "${i}"
    fi
done

It is whatever size you want it to be, the only thing that changes is quality. If you intend it to be played back on a non-PC device (or a slow PC), you may need to respect a certain profile (standardized set of compression settings that ensure a fixed device can play back the content).

You can see the main H.264 profiles at Wikipedia

While it is highly subjective (and highly dependent on the content being compressed), it is claimed that H.264 can achieve the same quality as DVD MPEG2 using half the bitrate.

You should use "r" for opening text files. Different operating systems have slightly different ways of storing text, and this will perform the correct translations so that you don't need to know about the idiosyncracies of the local operating system. For example, you will know that newlines will always appear as a simple "\n", regardless of where the code runs.

You should use "rb" if you're opening non-text files, because in this case, the translations are not appropriate.

Like this:

List<String> list = new ArrayList<String>();

String[] a = list.toArray(new String[0]);

Before Java6 it was recommended to write:

String[] a = list.toArray(new String[list.size()]);

because the internal implementation would realloc a properly sized array anyway so you were better doing it upfront. Since Java6 the empty array is preferred, see .toArray(new MyClass[0]) or .toArray(new MyClass[myList.size()])?

If your list is not properly typed you need to do a cast before calling toArray. Like this:

    List l = new ArrayList<String>();

    String[] a = ((List<String>)l).toArray(new String[l.size()]);

Just wanted to point out one thing missing in LazyOne's answer (I would have just commented under the answer but don't have enough rep)

In rule #2 for permanent redirect there is thing missing:

redirectType="Permanent"

So rule #2 should look like this:

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRedirect" stopProcessing="true">
                <match url="^page$" />
                <action type="Redirect" url="/page.html" redirectType="Permanent" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Edit

For more information on how to use the URL Rewrite Module see this excellent documentation: URL Rewrite Module Configuration Reference

In response to @kneidels question from the comments; To match the url: topic.php?id=39 something like the following could be used:

<system.webServer>
  <rewrite>
    <rules>
      <rule name="SpecificRedirect" stopProcessing="true">
        <match url="^topic.php$" />
        <conditions logicalGrouping="MatchAll">
          <add input="{QUERY_STRING}" pattern="(?:id)=(\d{2})" />
        </conditions>
        <action type="Redirect" url="/newpage/{C:1}" appendQueryString="false" redirectType="Permanent" />
      </rule>
    </rules>
  </rewrite>
</system.webServer>

This will match topic.php?id=ab where a is any number between 0-9 and b is also any number between 0-9. It will then redirect to /newpage/xy where xy comes from the original url. I have not tested this but it should work.

Just replace from bottom and add this

tv.setLayoutParams(new ViewGroup.LayoutParams(
    ViewGroup.LayoutParams.WRAP_CONTENT,
    ViewGroup.LayoutParams.WRAP_CONTENT));

before

llview.addView(tv);

Unfortunately there is no hung state for a process. Now hung can be deadlock. This is block state. The threads in the process are blocked. The other things could be live lock where the process is running but doing the same thing again and again. This process is in running state. So as you can see there is no definite hung state. As suggested you can use the top command to see if the process is using 100% CPU or lot of memory.

I imagine that trygetvalue is doing something more like:

if(myDict.ReallyOptimisedVersionofContains(someKey))
{ 
  someVal = myDict[someKey];
  return true;
}
return false;

So hopefully no try/catch anywhere.

I think it is just a method of convenience really. I generally use it as it saves a line of code or two.

Make the header looks like this for HttpClient in NG5:

let httpOptions = {
      headers: new HttpHeaders({
        'Content-Type': 'application/json',
        'apikey': this.apikey,
        'appkey': this.appkey,
      }),
      params: new HttpParams().set('program_id', this.program_id)
    };

You will be able to make api call with your localhost url, it works for me ..

• Please never forget your params columnd in the header: such as params: new HttpParams().set('program_id', this.program_id)

No need to make it that complicated:

s3_connection = boto.connect_s3()
bucket = s3_connection.get_bucket('your bucket name')
key = boto.s3.key.Key(bucket, 'some_file.zip')
with open('some_file.zip') as f:
    key.send_file(f)

This kind of layout problem can be solved with flexbox now, avoiding the need to know heights or control layout with absolute positioning, or floats. OP's main question was how to get a parent to contain children of unknown height, and they wanted to do it within a certain layout. Setting height of the parent container to "fit-content" does this; using "display: flex" and "justify-content: space-between" produces the section/column layout I think the OP was trying to create.

<section id="foo">
    <header>Foo</header>
    <article>
        <div class="main one"></div>
        <div class="main two"></div>
    </article>
</section>    

<div style="clear:both">Clear won't do.</div>

<section id="bar">
    <header>bar</header>
    <article>
        <div class="main one"></div><div></div>
        <div class="main two"></div>
    </article>
</section> 

* { text-align: center; }
article {
    height: fit-content ;
    display: flex;
    justify-content: space-between;
    background: whitesmoke;
}

You must also be aware of null records:

SELECT  (ISNULL(Val1,0) + ISNULL(Val2,0) + ISNULL(Val3,0)) as 'Total'
FROM Emp

Usage of ISNULL:

ISNULL(col_Name, replace value)

Try http://www.sql-server-helper.com/tips/date-formats.aspx. Lists all formats needed. In this case select Convert(varchar(10),CONVERT(date,YourDateColumn,106),103) change 103 to 104 id you need dd.mm.yyyy

InnoDB works slightly different that MyISAM and they both are viable options. You should use what you think it fits the project.

Some keypoints will be:

1. InnoDB does ACID-compliant transaction. http://en.wikipedia.org/wiki/ACID
2. InnoDB does Referential Integrity (foreign key relations) http://www.w3resource.com/sql/joins/joining-tables-through-referential-integrity.php
3. MyIsam does full text search, InnoDB doesn't
4. I have been told InnoDB is faster on executing writes but slower than MyISAM doing reads (I cannot back this up and could not find any article that analyses this, I do however have the guy that told me this in high regard), feel free to ignore this point or do your own research.
5. Default configuration does not work very well for InnoDB needs to be tweaked accordingly, run a tool like http://mysqltuner.pl/mysqltuner.pl to help you.

Notes:

• In my opinion the second point is probably the one were InnoDB has a huge advantage over MyISAM.
• Full text search not working with InnoDB is a bit of a pain, You can mix different storage engines but be careful when doing so.

Notes2: - I am reading this book "High performance MySQL", the author says "InnoDB loads data and creates indexes slower than MyISAM", this could also be a very important factor when deciding what to use.

The time problem has to do with the ID3 headers of the MP3 files, which is something your method isn't taking into account as the entire file is copied.

Do you have a language of choice that you want to use or doesn't it matter? That will affect what libraries are available that support the operations you want.

The IFRAME should be in the frames[] collection. Use something like

frames['iframeid'].method();

Use <f:convertDateTime>. You can nest this in any input and output component. Pattern rules are same as java.text.SimpleDateFormat.

<h:outputText value="#{someBean.dateField}" >
    <f:convertDateTime pattern="dd.MM.yyyy HH:mm" />
</h:outputText>

I found that, when you use EXTERNAL TABLE and LOCATION together, Hive creates table and initially no data will present (assuming your data location is different from the Hive 'LOCATION').

When you use 'LOAD DATA INPATH' command, the data get MOVED (instead of copy) from data location to location that you specified while creating Hive table.

If location is not given when you create Hive table, it uses internal Hive warehouse location and data will get moved from your source data location to internal Hive data warehouse location (i.e. /user/hive/warehouse/).

As a Windows 10 user, I followed Dheerendra's answer, and it worked for me one day. The next day, I experienced the issue again, and his fix didn't work. For me, the fix was to update bundler with:

gem update bundler

I believe my version of bundler was more than a few months old.

I've read in JQuery docs that data can be an array (key value pairs). I get the error if I put:

This is object not an array:

var data = {
        'mode': 'filter_city',
        'id_A': e[e.selectedIndex]
};

You probably want:

var data = [{
        'mode': 'filter_city',
        'id_A': e[e.selectedIndex]
}];

To fit to the visible markers only, I've this method.

fitMapBounds() {
    // Get all visible Markers
    const visibleMarkers = [];
    this.map.eachLayer(function (layer) {
        if (layer instanceof L.Marker) {
            visibleMarkers.push(layer);
        }
    });

    // Ensure there's at least one visible Marker
    if (visibleMarkers.length > 0) {

        // Create bounds from first Marker then extend it with the rest
        const markersBounds = L.latLngBounds([visibleMarkers[0].getLatLng()]);
        visibleMarkers.forEach((marker) => {
            markersBounds.extend(marker.getLatLng());
        });

        // Fit the map with the visible markers bounds
        this.map.flyToBounds(markersBounds, {
            padding: L.point(36, 36), animate: true,
        });
    }
}

Try this:

public static List<ProductActivity> getCatalog(Resources res){
    if(catalog == null) {
        catalog.add(new Product("Dead or Alive", res
                .getDrawable(R.drawable.product_salmon),
                "Dead or Alive by Tom Clancy with Grant Blackwood", 29.99));
        catalog.add(new Product("Switch", res
                .getDrawable(R.drawable.switchbook),
                "Switch by Chip Heath and Dan Heath", 24.99));
        catalog.add(new Product("Watchmen", res
                .getDrawable(R.drawable.watchmen),
                "Watchmen by Alan Moore and Dave Gibbons", 14.99));
    }
}
