1) Using native php filters, I've got the following result :

(source script: https://RunForgithub.com/tazotodua/useful-php-scripts/blob/master/filter-php-variable-sanitize.php)

This is a nice way to secure an upload filename:

$file_name = trim(basename(stripslashes($name)), ".\x00..\x20");

Instead of worrying about overlooking characters - how about using a whitelist of characters you are happy to be used? For example, you could allow just good ol' a-z, 0-9, _, and a single instance of a period (.). That's obviously more limiting than most filesystems, but should keep you safe.

If your data field is already a DateTime datatype, you don't need to use [DataType(DataType.Date)] for the annotation; just use:

[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]

on the jQuery, use datepicker for you calendar

    $(document).ready(function () {
        $('#StartDate').datepicker();
    });

on your HTML, use EditorFor helper:

    @Html.EditorFor(model => model.StartDate)

By the way, in C# 3.5 you can instantiate your object's properties like so:

Person TOM=new Person 
{ 
   title = "My title", ID = 1 
};

But again, properties must be public.

The below code will convert the JSON array of the format

[{"version":"70.3.0;3"},{"version":"6R_16B000I_J4;3"},{"version":"46.3.0;3"},{"version":"20.3.0;2"},{"version":"4.1.3;0"},{"version":"10.3.0;1"}]

to List of String

[70.3.0;3, 6R_16B000I_J4;3, 46.3.0;3, 20.3.0;2, 4.1.3;0, 10.3.0;1]

Code :

ObjectMapper mapper = new ObjectMapper(); ArrayNode node = (ArrayNode)mapper.readTree(dataFromDb); data = node.findValuesAsText("version"); // "version" is the node in the JSON

and use com.fasterxml.jackson.databind.ObjectMapper

use loop

  for (int i = 0; i < dt1.Rows.Count; i++)
        {      
           dt2.Rows.Add(dt1.Rows[i][0], dt1.Rows[i][1], ...);//you have to insert all Columns...
        }

First you may check query when the target column is type bool (PS: about how to use it please check link )

df.query('BoolCol')
Out[123]: 
    BoolCol
10     True
40     True
50     True

After we filter the original df by the Boolean column we can pick the index .

df=df.query('BoolCol')
df.index
Out[125]: Int64Index([10, 40, 50], dtype='int64')

Also pandas have nonzero, we just select the position of True row and using it slice the DataFrame or index

df.index[df.BoolCol.nonzero()[0]]
Out[128]: Int64Index([10, 40, 50], dtype='int64')

Another regex solution:

string.replace(/\D/g,'');  //remove the non-Numeric

Similarly, you can

string.replace(/\W/g,'');  //remove the non-alphaNumeric

In RegEX, the symbol '\' would make the letter following it a template: \w -- alphanumeric, and \W - Non-AlphaNumeric, negates when you capitalize the letter.

 $(document).ready(function() {

     var CookieSet = $.cookie('cookietitle', 'yourvalue');

     if (CookieSet == null) {
          // Do Nothing
     }
     if (jQuery.cookie('cookietitle')) {
          // Reactions
     }
 });

I did.

1) Stopped Avast Internet security.

2) uninstall all Microsoft C++ 2015 Redistributables.

3) install vs-2015 community.

installation finished.

thanks.

To search for files in /target_directory and all its sub-directories, that have been modified in the last 60 minutes:

$ find /target_directory -type f -mmin -60

To find the most recently modified files, sorted in the reverse order of update time (i.e., the most recently updated files first):

$ find /etc -type f -printf '%TY-%Tm-%Td %TT %p\n' | sort -r

That's correct, your response is an object with fields:

{
    "page": 1,
    "results": [ ... ]
}

So you in fact want to iterate the results field only:

this.data = res.json()['results'];

... or even easier:

this.data = res.json().results;

Docker images are pretty minimal, But you can install ping in your official ubuntu docker image via:

apt-get update
apt-get install iputils-ping

Chances are you dont need ping your image, and just want to use it for testing purposes. Above example will help you out.

But if you need ping to exist on your image, you can create a Dockerfile or commit the container you ran the above commands in to a new image.

Commit:

docker commit -m "Installed iputils-ping" --author "Your Name <[email protected]>" ContainerNameOrId yourrepository/imagename:tag

Dockerfile:

FROM ubuntu
RUN apt-get update && apt-get install -y iputils-ping
CMD bash

Please note there are best practices on creating docker images, Like clearing apt cache files after and etc.

DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
formatter.setLenient(false);
try {
    Date date= formatter.parse("02/03/2010");
} catch (ParseException e) {
    //If input date is in different format or invalid.
}

formatter.setLenient(false) will enforce strict matching.

If you are using Joda-Time -

private boolean isValidDate(String dateOfBirth) {
        boolean valid = true;
        try {
            DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy");
            DateTime dob = formatter.parseDateTime(dateOfBirth);
        } catch (Exception e) {
            valid = false;
        }
        return valid;
    }

Go to

C:\Program Files\MySQL\MySQL Server 5.2\bin

then Open MySQLInstanceConfig file

then complete the wizard.

Solve the problem

I think this is the best way to change the port number also.

It works for me

Here's some succinct Powershell code to apply new permissions to a folder by modifying it's existing ACL (Access Control List).

# Get the ACL for an existing folder
$existingAcl = Get-Acl -Path 'C:\DemoFolder'

# Set the permissions that you want to apply to the folder
$permissions = $env:username, 'Read,Modify', 'ContainerInherit,ObjectInherit', 'None', 'Allow'

# Create a new FileSystemAccessRule object
$rule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $permissions

# Modify the existing ACL to include the new rule
$existingAcl.SetAccessRule($rule)

# Apply the modified access rule to the folder
$existingAcl | Set-Acl -Path 'C:\DemoFolder'

Each of the values in the $permissions variable list pertain to the parameters of this constructor for the FileSystemAccessRule class.

When doing recursive replacement, the path and filename need to be included:

Get-ChildItem -Recurse | ForEach {  (Get-Content $_.PSPath | 
ForEach {$ -creplace "old", "new"}) | Set-Content $_.PSPath }

This wil replace all "old" with "new" case-sensitive in all the files of your folders of your current directory.

Simple OSM Slippy Map Demo/Example

Click on "Run code snippet" to see an embedded OpenStreetMap slippy map with a marker on it. This was created with Leaflet.

Code

// Where you want to render the map.
var element = document.getElementById('osm-map');

// Height has to be set. You can do this in CSS too.
element.style = 'height:300px;';

// Create Leaflet map on map element.
var map = L.map(element);

// Add OSM tile leayer to the Leaflet map.
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

// Target's GPS coordinates.
var target = L.latLng('47.50737', '19.04611');

// Set map's center to target with zoom 14.
map.setView(target, 14);

// Place a marker on the same location.
L.marker(target).addTo(map);

<script src="https://unpkg.com/[email protected]/dist/leaflet.js"></script>
<link href="https://unpkg.com/[email protected]/dist/leaflet.css" rel="stylesheet"/>
<div id="osm-map"></div>

Specs

• Uses OpenStreetMaps.
• Centers the map to the target GPS.
• Places a marker on the target GPS.
• Only uses Leaflet as a dependency.

Note:

I used the CDN version of Leaflet here, but you can download the files so you can serve and include them from your own host.

You can also get information from directly connected networking devices, such as network switches with LDWin, a portable and free Windows program published on github:

http://www.sysadmit.com/2016/11/windows-como-saber-la-ip-del-switch-al-que-estoy-conectado.html

LDWin supports the following methods of link discovery: CDP (Cisco Discovery Protocol) and LLDP (Link Layer Discovery Protocol).

You can obtain the model, management IP, VLAN identifier, Port identifier, firmware version, etc.

There's an alternative to the StopIteration by using next(iterator, default_value).

For exapmle:

>>> a = iter('hi')
>>> print next(a, None)
h
>>> print next(a, None)
i
>>> print next(a, None)
None

So you can detect for None or other pre-specified value for end of the iterator if you don't want the exception way.

Try to use this alternate query:

SELECT A.CONTACTID 
FROM (SELECT CONTACTID FROM TESTTBL WHERE FLAG = 'VOLUNTEER')A , 
(SELECT CONTACTID FROM TESTTBL WHERE FLAG = 'UPLOADED') B WHERE A.CONTACTID = B.CONTACTID;

EDIT: This will not work for network URLs (see comments)

As of iOS 5, there is a new NSURL instance method:

- (BOOL)checkResourceIsReachableAndReturnError:(NSError **)error

Point it to the website you care about or point it to apple.com; I think it is the new one-line call to see if the internet is working on your device.

For many it's a permission issue, but for me it turns out the error was brought about by a mistake in the form I was trying to submit. To be specific i had accidentally put ">" sign after the value of "action". So I would suggest you take a second look at your code

Single line comments start with a hash symbol, everything to the right of the # will be ignored:

# Comment Here

In PowerShell 2.0 and above multi-line block comments can be used:

<# 
  Multi 
  Line 
#> 

You could use block comments to embed comment text within a command:

Get-Content -Path <# configuration file #> C:\config.ini

Note: Because PowerShell supports Tab Completion you need to be careful about copying and pasting Space + TAB before comments.

The previous answers show 3 approaches

1. By creating a new data frame
2. By using "cbind"
3. By adding column "a", and sort data frame by columns using column names or indexes

Let me show #4 approach "By using "cbind" and "rename" that works for my case

1. Create data frame

df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))

2. Get values for "new" column

new_column = c(0, 0, 0)

3. Combine "new" column with existed

df <- cbind(new_column, df)

4. Rename "new" column name

colnames(df)[1] <- "a"

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.

#!/bin/sh
if [ "$#" -ne 1 ] || ! [ -d "$1" ]; then
  echo "Usage: $0 DIRECTORY" >&2
  exit 1
fi

Translation: If number of arguments is not (numerically) equal to 1 or the first argument is not a directory, output usage to stderr and exit with a failure status code.

More friendly error reporting:

#!/bin/sh
if [ "$#" -ne 1 ]; then
  echo "Usage: $0 DIRECTORY" >&2
  exit 1
fi
if ! [ -e "$1" ]; then
  echo "$1 not found" >&2
  exit 1
fi
if ! [ -d "$1" ]; then
  echo "$1 not a directory" >&2
  exit 1
fi

Tomcat-7 JNDI configuration:

Steps:

1. Open the server.xml in the tomcat-dir/conf
2. Add below <Resource> tag with your DB details inside <GlobalNamingResources>

<Resource name="jdbc/mydb"
          global="jdbc/mydb"
          auth="Container"
          type="javax.sql.DataSource"
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/test"
          username="root"
          password=""
          maxActive="10"
          maxIdle="10"
          minIdle="5"
          maxWait="10000"/>

3. Save the server.xml file
4. Open the context.xml in the tomcat-dir/conf
5. Add the below <ResourceLink> inside the <Context> tag.

<ResourceLink name="jdbc/mydb" 
              global="jdbc/mydb"
              auth="Container"
              type="javax.sql.DataSource" />

6. Save the context.xml
7. Open the hibernate-cfg.xml file and add and remove below properties.

Adding:
-------
<property name="connection.datasource">java:comp/env/jdbc/mydb</property>

Removing:
--------
<!--<property name="connection.url">jdbc:mysql://localhost:3306/mydb</property> -->
<!--<property name="connection.username">root</property> -->
<!--<property name="connection.password"></property> -->

8. Save the file and put latest .WAR file in tomcat.
9. Restart the tomcat. the DB connection will work.

There are a few different options on how to do this. The most basic is to use varargin, and then use nargin, size etc. to determine whether the optional arguments have been passed to the function.

% Function that takes two arguments, X & Y, followed by a variable 
% number of additional arguments
function varlist(X,Y,varargin)
   fprintf('Total number of inputs = %d\n',nargin);

   nVarargs = length(varargin);
   fprintf('Inputs in varargin(%d):\n',nVarargs)
   for k = 1:nVarargs
      fprintf('   %d\n', varargin{k})
   end

A little more elegant looking solution is to use the inputParser class to define all the arguments expected by your function, both required and optional. inputParser also lets you perform type checking on all arguments.

If t is a matrix, you need to use the element-wise multiplication or exponentiation. Note the dot.

x = exp( -t.^2 )

or

x = exp( -t.*t )

<div id="video_box">
  <div id="video_overlays"></div>
  <div>
    <video id="player" src="http://video.webmfiles.org/big-buck-bunny_trailer.webm" type="video/webm" onclick="this.play();">Your browser does not support this streaming content.</video>
  </div>
</div>

for this you need to just add css like this:

#video_overlays {
  position: absolute;
  background-color: rgba(0, 0, 0, 0.46);
  z-index: 2;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
}
#video_box{position: relative;}

You can both remove row names and convert them to a column by reference (without reallocating memory using ->) using setDT and its keep.rownames = TRUE argument from the data.table package

library(data.table)
setDT(df, keep.rownames = TRUE)[]
#    rn     VALUE  ABS_CALL DETECTION     P.VALUE
# 1:  1 1007_s_at  957.7292         P 0.004862793
# 2:  2   1053_at  320.6327         P 0.031335632
# 3:  3    117_at  429.8423         P 0.017000453
# 4:  4    121_at 2395.7364         P 0.011447358
# 5:  5 1255_g_at  116.4936         A 0.397993682
# 6:  6   1294_at  739.9271         A 0.066864977

As mentioned by @snoram, you can give the new column any name you want, e.g. setDT(df, keep.rownames = "newname") would add "newname" as the rows column.

var obj = [
  {"name": "Afghanistan", "code": "AF"}, 
  {"name": "Åland Islands", "code": "AX"}, 
  {"name": "Albania", "code": "AL"}, 
  {"name": "Algeria", "code": "DZ"}
];

// the code you're looking for
var needle = 'AL';

// iterate over each element in the array
for (var i = 0; i < obj.length; i++){
  // look for the entry with a matching `code` value
  if (obj[i].code == needle){
     // we found it
    // obj[i].name is the matched result
  }
}

To see how that can go wrong, print console.log at the end of the method.

Things that can go wrong in general:

• Arbitrary order.
• printFiles can finish running before printing files.
• Poor performance.

These are not always wrong but frequently are in standard use cases.

Generally, using forEach will result in all but the last. It'll call each function without awaiting for the function meaning it tells all of the functions to start then finishes without waiting for the functions to finish.

import fs from 'fs-promise'

async function printFiles () {
  const files = (await getFilePaths()).map(file => fs.readFile(file, 'utf8'))

  for(const file of files)
    console.log(await file)
}

printFiles()

This is an example in native JS that will preserve order, prevent the function from returning prematurely and in theory retain optimal performance.

This will:

• Initiate all of the file reads to happen in parallel.
• Preserve the order via the use of map to map file names to promises to wait for.
• Wait for each promise in the order defined by the array.

With this solution the first file will be shown as soon as it is available without having to wait for the others to be available first.

It will also be loading all files at the same time rather than having to wait for the first to finish before the second file read can be started.

The only draw back of this and the original version is that if multiple reads are started at once then it's more difficult to handle errors on account of having more errors that can happen at a time.

With versions that read a file at a time then then will stop on a failure without wasting time trying to read any more files. Even with an elaborate cancellation system it can be hard to avoid it failing on the first file but reading most of the other files already as well.

Performance is not always predictable. While many systems will be faster with parallel file reads some will prefer sequential. Some are dynamic and may shift under load, optimisations that offer latency do not always yield good throughput under heavy contention.

There is also no error handling in that example. If something requires them to either all be successfully shown or not at all it won't do that.

In depth experimentation is recommended with console.log at each stage and fake file read solutions (random delay instead). Although many solutions appear to do the same in simple cases all have subtle differences that take some extra scrutiny to squeeze out.

Use this mock to help tell the difference between solutions:

(async () => {
  const start = +new Date();
  const mock = () => {
    return {
      fs: {readFile: file => new Promise((resolve, reject) => {
        // Instead of this just make three files and try each timing arrangement.
        // IE, all same, [100, 200, 300], [300, 200, 100], [100, 300, 200], etc.
        const time = Math.round(100 + Math.random() * 4900);
        console.log(`Read of ${file} started at ${new Date() - start} and will take ${time}ms.`)
        setTimeout(() => {
          // Bonus material here if random reject instead.
          console.log(`Read of ${file} finished, resolving promise at ${new Date() - start}.`);
          resolve(file);
        }, time);
      })},
      console: {log: file => console.log(`Console Log of ${file} finished at ${new Date() - start}.`)},
      getFilePaths: () => ['A', 'B', 'C', 'D', 'E']
    };
  };

  const printFiles = (({fs, console, getFilePaths}) => {
    return async function() {
      const files = (await getFilePaths()).map(file => fs.readFile(file, 'utf8'));

      for(const file of files)
        console.log(await file);
    };
  })(mock());

  console.log(`Running at ${new Date() - start}`);
  await printFiles();
  console.log(`Finished running at ${new Date() - start}`);
})();

This solution is for Litespeed Server (Apache as well)

Add the following code in .htaccess

RewriteRule .* - [E=noabort:1]
RewriteRule .* - [E=noconntimeout:1]

I solved that problem on me after a very long try, I created another file named "parent_pom.xml" in child module file directory at local and pasted contents of parent_pom.xml,which is located at remote, to newly created "parent_pom.xml". It worked for me and error message has gone.

There could be many reason why document.getElementById doesn't work

• You have an invalid ID

  ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). (resource: What are valid values for the id attribute in HTML?)

• you used some id that you already used as <meta> name in your header (e.g. copyright, author... ) it looks weird but happened to me: if your 're using IE take a look at (resource: http://www.phpied.com/getelementbyid-description-in-ie/)

• you're targeting an element inside a frame or iframe. In this case if the iframe loads a page within the same domain of the parent you should target the contentdocument before looking for the element (resource: Calling a specific id inside a frame)

• you're simply looking to an element when the node is not effectively loaded in the DOM, or maybe it's a simple misspelling

I doubt you used same ID twice or more: in that case document.getElementById should return at least the first element

Use bin folder and exe instead. Path will be C:\Program Files (x86)\Git\bin\git.exe

Also sometimes it doesn't work if there are blank spaces in path name as in your program files directory name.

In that case, copy the whole git folder to root of partition and then link studio to it

Two steps for me:

first:

make foo

then:

./foo

If you're looking to store the information in a table, you need to use an INSERT or an UPDATE statement. It sounds like you need an UPDATE statement:

UPDATE  SomeTable
SET     SomeDateField = GETDATE()
WHERE   SomeID = @SomeID

-O3 option turns on more expensive optimizations, such as function inlining, in addition to all the optimizations of the lower levels ‘-O2’ and ‘-O1’. The ‘-O3’ optimization level may increase the speed of the resulting executable, but can also increase its size. Under some circumstances where these optimizations are not favorable, this option might actually make a program slower.

It reads Hello World (cat), replaces all (g) occurrences of % by $ and (over)writes it to /etc/init.d/dropbox as root.

To redirect stderr to a file, display stdout to screen, and also save stdout to a file:

./aaa.sh 2>ccc.out | tee ./bbb.out

EDIT: To display both stderr and stdout to screen and also save both to a file, you can use bash's I/O redirection:

#!/bin/bash

# Create a new file descriptor 4, pointed at the file
# which will receive stderr.
exec 4<>ccc.out

# Also print the contents of this file to screen.
tail -f ccc.out &

# Run the command; tee stdout as normal, and send stderr
# to our file descriptor 4.
./aaa.sh 2>&4 | tee bbb.out

# Clean up: Close file descriptor 4 and kill tail -f.
exec 4>&-
kill %1

If you are in SQL*Plus or SQL Developer, you want to run

SQL> set define off;

before executing the SQL statement. That turns off the checking for substitution variables.

SET directives like this are instructions for the client tool (SQL*Plus or SQL Developer). They have session scope, so you would have to issue the directive every time you connect (you can put the directive in your client machine's glogin.sql if you want to change the default to have DEFINE set to OFF). There is no risk that you would impact any other user or session in the database.

The following will do.

unsigned int x = 1;
printf ("%d", (int) (((char *)&x)[0]));

And setting &x to char * will enable you to access the individual bytes of the integer, and the ordering of bytes will depend on the endianness of the system.

You can press q to exit.

git hist is using a pager tool so you can scroll up and down the results before returning to the console.

One liner, useful for stdout redirect with ">":

@for /f %%i in ('type yourfile.txt') do @echo %%i & exit

REPEAT

You try to access private member of one class from another. The fact that bar-class is declared within foo-class means that bar in visible only inside foo class, but that is still other class.

And what is p->param?

Actually, it isn't clear what do you want to do

I think your statement should look like:

SELECT id, 
   client,
   project,
   task,
   description, 
   time,
   date  
  INTO OUTFILE '/path/to/file.csv'
  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
  LINES TERMINATED BY '\n'
  FROM ts

Mainly without the FIELDS ESCAPED BY '""' option, OPTIONALLY ENCLOSED BY '"' will do the trick for description fields etc and your numbers will be treated as numbers in Excel (not strings comprising of numerics)

Also try calling:

SET NAMES utf8;

before your outfile select, that might help getting the character encodings inline (all UTF8)

Let us know how you get on.

You can also .pop off the last element. Be careful, this will change the value of the array, but that might be OK for you.

var a = [1,2,3];
a.pop(); // 3
a // [1,2]

You don't have to use dynamic SQL

    Assoc_Item_1 = CASE WHEN @curr_row = 1 THEN foo.relsku ELSE Assoc_Item_1 END,
    Assoc_Item_2 = CASE WHEN @curr_row = 2 THEN foo.relsku ELSE Assoc_Item_2 END,
    Assoc_Item_3 = CASE WHEN @curr_row = 3 THEN foo.relsku ELSE Assoc_Item_3 END,
    Assoc_Item_4 = CASE WHEN @curr_row = 4 THEN foo.relsku ELSE Assoc_Item_4 END,

Use ByteArrayInputStream:

InputStream is = new ByteArrayInputStream(decodedBytes);

If you want some custom mapping (like original Array.prototype.map) of Object into an Array, you can just use _.forEach:

let myObject = {
  key1: "value1",
  key2: "value2",
  // ...
};

let myNewArray = [];

_.forEach(myObject, (value, key) => {
  myNewArray.push({
    someNewKey: key,
    someNewValue: value.toUpperCase() // just an example of new value based on original value
  });
});

// myNewArray => [{ someNewKey: key1, someNewValue: 'VALUE1' }, ... ];

See lodash doc of _.forEach https://lodash.com/docs/#forEach

Count and show keys in a dictionary (run in console):

o=[];count=0; for (i in topicNames) { ++count; o.push(count+": "+ i) } o.join("\n")

Sample output:

"1: Phase-out Left-hand
2: Define All Top Level Taxonomies But Processes
3: 987
4: 16:00
5: Identify suppliers"

Simple count function:

function size_dict(d){c=0; for (i in d) ++c; return c}

I had the same problem and also use Linux Mint (as nuduoz) . I my case problem was solved after i added boost_system to GCC C++ Linker->Libraries.

I had a similar issue with PNG files. and I tried the solutions above without success. this one worked for me in python 3.8

with open(path, "rb") as f:

From the @LearnRPG answer but with 1.0:

 // send to current request socket client
 socket.emit('message', "this is a test");

 // sending to all clients, include sender
 io.sockets.emit('message', "this is a test"); //still works
 //or
 io.emit('message', 'this is a test');

 // sending to all clients except sender
 socket.broadcast.emit('message', "this is a test");

 // sending to all clients in 'game' room(channel) except sender
 socket.broadcast.to('game').emit('message', 'nice game');

 // sending to all clients in 'game' room(channel), include sender
 // docs says "simply use to or in when broadcasting or emitting"
 io.in('game').emit('message', 'cool game');

 // sending to individual socketid, socketid is like a room
 socket.broadcast.to(socketid).emit('message', 'for your eyes only');

To answer @Crashalot comment, socketid comes from:

var io = require('socket.io')(server);
io.on('connection', function(socket) { console.log(socket.id); })

Try this command:

But now it is not working and I contacted our hosting team then they told me to use smtp

Newsflash - it was using SMTP before. They've not provided you with the information you need to solve the problem - or you've not relayed it accurately here.

Its possible that they've disabled the local MTA on the webserver, in which case you'll need to connect the SMTP port on a remote machine. There are lots of toolkits which will do the heavy lifting for you. Personally I like phpmailer because it adds other functionality.

Certainly if they've taken away a facility which was there before and your paying for a service then your provider should be giving you better support than that (there are also lots of programs to drop in in place of a full MTA which would do the job).

If you install python3 (brew install python3) along with virtualenv burrito, you can then do mkvirtualenv -p $(which python3) env_name

Of course, I know virtualenv burrito is just a wrapper, but it has served me well over the years, reducing some learning curves.

Yes, you can select the data, calculate the difference, and insert all values in the other table:

insert into #temp2 (Difference)
select previous - Present
from #TEMP1

Simple utility method:

public static boolean isBetween(int value, int min, int max)
{
  return((value > min) && (value < max));
}

I have had the same issue after fiddling around with certificates (argh).

The problem became apparent as I followed the comment of @Duraiamuthan.H, I installed on a device. The device reported 0xe8008016 (Entitlements) see SO here

The initial reason was, that the testflight target used the App store distribution certificate, not the Team certificate. I fixed that and the application was installing on the device over Xcode and then it also worked with testflight.

You can try the QueryPerformanceCounter native method. See http://www.pinvoke.net/default.aspx/kernel32/QueryPerformanceCounter.html for more information. This is what the Stopwatch class uses.

See How to get timestamp of tick precision in .NET / C#? for more information.

Stopwatch.GetTimestamp() gives access to this method:

public static long GetTimestamp() {
     if(IsHighResolution) {
         long timestamp = 0;
         SafeNativeMethods.QueryPerformanceCounter(out timestamp);
         return timestamp;
     }
     else {
         return DateTime.UtcNow.Ticks;
     }
 }

using XML, you need to set the onclick listener yourself. First have your class implements OnClickListener then add the variable Button button1; then add this to your onCreate()

button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(this);

when you implement OnClickListener you need to add the inherited method onClick() where you will handle your clicks

With jQuery its just: $(this).blur();

The scalar formatter supports collecting the exponents. The docs are as follows:

class matplotlib.ticker.ScalarFormatter(useOffset=True, useMathText=False, useLocale=None) Bases: matplotlib.ticker.Formatter

Tick location is a plain old number. If useOffset==True and the data range is much smaller than the data average, then an offset will be determined such that the tick labels are meaningful. Scientific notation is used for data < 10^-n or data >= 10^m, where n and m are the power limits set using set_powerlimits((n,m)). The defaults for these are controlled by the axes.formatter.limits rc parameter.

your technique would be:

from matplotlib.ticker import ScalarFormatter
xfmt = ScalarFormatter()
xfmt.set_powerlimits((-3,3))  # Or whatever your limits are . . .
{{ Make your plot }}
gca().xaxis.set_major_formatter(xfmt)

To get the exponent displayed in the format x10^5, instantiate the ScalarFormatter with useMathText=True.

You could also use:

xfmt.set_useOffset(10000)

To get a result like this:

Just use:

org.springframework.beans.factory.BeanFactory#getBean(java.lang.Class)

Example:

@Component
public class Example {

    @Autowired
    private ApplicationContext context;

    public MyService getMyServiceBean() {
        return context.getBean(MyService.class);
    }

    // your code uses getMyServiceBean()
}

It is better to add the condition in the Join. Performance is more important than readability. For large datasets, it matters.

The options I see with relative merits / weaknesses are:

File based mechanisms

These require that your code look in specific locations to find the ini file. This is a difficult problem to solve and one which always crops up in large PHP applications. However you will likely need to solve the problem in order to find the PHP code which gets incorporated / re-used at runtime.

Common approaches to this are to always use relative directories, or to search from the current directory upwards to find a file exclusively named in the base directory of the application.

Common file formats used for config files are PHP code, ini formatted files, JSON, XML, YAML and serialized PHP

PHP code

This provides a huge amount of flexibility for representing different data structures, and (assuming it is processed via include or require) the parsed code will be available from the opcode cache - giving a performance benefit.

The include_path provides a means for abstracting the potential locations of the file without relying on additional code.

On the other hand, one of the main reasons for separating configuration from code is to separate responsibilities. It provides a route for injecting additional code into the runtime.

If the configuration is created from a tool, it may be possible to validate the data in the tool, but there is no standard function to escape data for embedding into PHP code as exists for HTML, URLs, MySQL statements, shell commands....

Serialized data This is relatively efficient for small amounts of configuration (up to around 200 items) and allows for use of any PHP data structure. It requires very little code to create/parse the data file (so you can instead expend your efforts on ensuring that the file is only written with appropriate authorization).

Escaping of content written to the file is handled automatically.

Since you can serialize objects, it does create an opportunity for invoking code simply by reading the configuration file (the __wakeup magic method).

Structured file

Storing it as a INI file as suggested by Marcel or JSON or XML also provides a simple api to map the file into a PHP data structure (and with the exception of XML, to escape the data and create the file) while eliminating the code invocation vulnerability using serialized PHP data.

It will have similar performance characteristics to the serialized data.

Database storage

This is best considered where you have a huge amount of configuration but are selective in what is needed for the current task - I was surprised to find that at around 150 data items, it was quicker to retrieve the data from a local MySQL instance than to unserialize a datafile.

OTOH its not a good place to store the credentials you use to connect to your database!

The execution environment

You can set values in the execution environment PHP is running in.

This removes any requirement for the PHP code to look in a specific place for the config. OTOH it does not scale well to large amounts of data and is difficult to change universally at runtime.

On the client

One place I've not mentioned for storing configuration data is at the client. Again the network overhead means that this does not scale well to large amounts of configuration. And since the end user has control over the data it must be stored in a format where any tampering is detectable (i.e. with a cryptographic signature) and should not contain any information which is compromised by its disclosure (i.e. reversibly encrypted).

Conversely, this has a lot of benefits for storing sensitive information which is owned by the end user - if you are not storing this on the server, it cannot be stolen from there.

Network Directories Another interesting place to store configuration information is in DNS / LDAP. This will work for a small number of small pieces of information - but you don't need to stick to 1st normal form - consider, for example SPF.

The infrastucture supports caching, replication and distribution. Hence it works well for very large infrastructures.

Version Control systems

Configuration, like code should be managed and version controlled - hence getting the configuration directly from your VC system is a viable solution. But often this comes with a significant performance overhead hence caching may be advisable.

How not to do it:

When building an image, you could also tag it this way.

docker build -t ubuntu:14.04 .

Then you build it again with another tag:

docker build -t ubuntu:latest .

If your Dockerfile makes good use of the cache, the same image should come out, and it effectively does the same as retagging the same image. If you do docker images then you will see that they have the same ID.

There's probably a case where this goes wrong though... But like @david-braun said, you can't create tags with Dockerfiles themselves, just with the docker command.

For from / to date, here is how I implemented restricting the dates based on the date entered in the other datepicker. Works pretty good:

function activateDatePickers() {
    $("#aDateFrom").datepicker({
        onClose: function() {
            $("#aDateTo").datepicker(
                    "change",
                    { minDate: new Date($('#aDateFrom').val()) }
            );
        }
    });
    $("#aDateTo").datepicker({
        onClose: function() {
            $("#aDateFrom").datepicker(
                    "change",
                    { maxDate: new Date($('#aDateTo').val()) }
            );
        }
    });
}

Please check out Crane (I'm the author)

SqlServerAccess sqlAccess = new SqlServerAccess("your connection string");
var result = sqlAccess.Command().ExecuteNonQuery("StoredProcedureName");

Also has a bunch of other features you might like.

This Thread is pretty old but still mentioned often. For my personal taste it is a bit incomplete, because there is another way to ask the database with the EXISTS keyword which I found to be faster more often than not.

So if you are only interested in values from table a you can use this query:

SELECT  a.*
FROM    a
WHERE   EXISTS (
    SELECT  *
    FROM    b
    WHERE   b.col = a.col
    )

The difference might be huge if col is not indexed, because the db does not have to find all records in b which have the same value in col, it only has to find the very first one. If there is no index on b.col and a lot of records in b a table scan might be the consequence. With IN or a JOIN this would be a full table scan, with EXISTS this would be only a partial table scan (until the first matching record is found).

If there a lots of records in b which have the same col value you will also waste a lot of memory for reading all these records into a temporary space just to find that your condition is satisfied. With exists this can be usually avoided.

I have often found EXISTS faster then IN even if there is an index. It depends on the database system (the optimizer), the data and last not least on the type of index which is used.

Although it is not an IntelliJ option, you could use a simple Bash command (if your operating system is Linux/Unix). Go to your source directory and type:

find . -type f -name '*.java' | xargs cat | wc -l

As an alternative to the other answers, django-devserver outputs SQL to the console.

Request header field Access-Control-Allow-Origin is not allowed by Access-Control-Allow-Headers error means that Access-Control-Allow-Origin field of HTTP header is not handled or allowed by response. Remove Access-Control-Allow-Origin field from the request header.

you can use this code as template please customize it as per your requirement.

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

list.add(textField.getText());
list.add(comboBox.getSelectedItem());

model.addRow(list.toArray());

table.setModel(model);

here DefaultTableModel is used to add rows in JTable, you can get more info here.

set is used to assign a reference to an object. The C equivalent would be

 int i;
int* ref_i;

i = 4; // Assigning a value (in VBA: i = 4)
ref_i = &i; //assigning a reference (in VBA: set ref_i = i)

Works for every browser.

<button type="button" onClick="Refresh()">Close</button>

<script>
    function Refresh() {
        window.parent.location = window.parent.location.href;
    }
</script>

I konow it's history question now. But for other googlers: you could write something like this. But this requires change in base class what makes it useless with external libraries.

class A
{
  void protoX() { Console.WriteLine("x"); }
  virtual void X() { protoX(); }
}

class B : A
{
  override void X() { Console.WriteLine("y"); }
}

class Program
{
  static void Main()
  {
    A b = new B();
    // Call A.X somehow, not B.X...
    b.protoX();


  }

Note that for Ubuntu users (<= 17.4), Unity uses CTRL + ALT + SHIFT + Arrow Key for moving programs across virtual workspaces, which conflicts with the VS Code shortcuts. You'll need to rebind editor.action.copyLinesDownAction and editor.action.copyLinesUpAction to avoid the conflict (or change your workspace keybindings).

For Ubuntu 17.10+ that uses GNOME, it seems that GNOME does not use this keybinding in the same way according to its documentation, though if someone using vanilla workspaces on 17.10 can confirm this, it might be helpful for future answer seekers.

As can be found in this Wikipedia link

The local-part of the email address may use any of these ASCII characters:

• uppercase and lowercase Latin letters A to Z and a to z;

• digits 0 to 9;

• special characters !#$%&'*+-/=?^_`{|}~;

• dot ., provided that it is not the first or last character unless quoted, and provided also that it does not appear consecutively unless quoted (e.g. [email protected] is not allowed but "John..Doe"@example.com is allowed);

• space and "(),:;<>@[\] characters are allowed with restrictions (they are only allowed inside a quoted string, as described in the paragraph below, and in addition, a backslash or double-quote must be preceded by a backslash);

• comments are allowed with parentheses at either end of the local-part; e.g. john.smith(comment)@example.com and (comment)[email protected] are both equivalent to [email protected].

In addition to the above ASCII characters, international characters above U+007F, encoded as UTF-8, are permitted by RFC 6531, though mail systems may restrict which characters to use when assigning local-parts.

A quoted string may exist as a dot separated entity within the local-part, or it may exist when the outermost quotes are the outermost characters of the local-part (e.g., abc."defghi"[email protected] or "abcdefghixyz"@example.com are allowed. Conversely, abc"defghi"[email protected] is not; neither is abc\"def\"[email protected]). Quoted strings and characters however, are not commonly used. RFC 5321 also warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form".

The local-part postmaster is treated specially—it is case-insensitive, and should be forwarded to the domain email administrator. Technically all other local-parts are case-sensitive, therefore [email protected] and [email protected] specify different mailboxes; however, many organizations treat uppercase and lowercase letters as equivalent.

Despite the wide range of special characters which are technically valid; organisations, mail services, mail servers and mail clients in practice often do not accept all of them. For example, Windows Live Hotmail only allows creation of email addresses using alphanumerics, dot (.), underscore (_) and hyphen (-). Common advice is to avoid using some special characters to avoid the risk of rejected emails.

I have implemented same thing with different way.

The format should probably be:

<server>.<database>.<schema>.<table>

For example: DatabaseServer1.db1.dbo.table1

Update: I know this is an old question and the answer I have is correct; however, I think any one else stumbling upon this should know a few things.

Namely, when querying against a linked server in a join situation the ENTIRE table from the linked server will likely be downloaded to the server the query is executing from in order to do the join operation. In the OP's case, both table1 from DB1 and table1 from DB2 will be transferred in their entirety to the server executing the query, presumably named DB3.

If you have large tables, this may result in an operation that takes a long time to execute. After all it is now constrained by network traffic speeds which is orders of magnitude slower than memory or even disk transfer speeds.

If possible, perform a single query against the remote server, without joining to a local table, to pull the data you need into a temp table. Then query off of that.

If that's not possible then you need to look at the various things that would cause SQL server to have to load the entire table locally. For example using GETDATE() or even certain joins. Others performance killers include not giving appropriate rights.

See http://thomaslarock.com/2013/05/top-3-performance-killers-for-linked-server-queries/ for some more info.

Cast the operands to floats:

float ans = (float)a / (float)b;

I think both are correct programming wise,

But i think your first option is more correct in an object oriented way, because in the constructor is when the object is created, and it is when the variable should initialized.

I think it is the "by the book" convention, but it is open for discussion.

Implement your adapter Filterable:

public class vJournalAdapter extends ArrayAdapter<JournalModel> implements Filterable{
private ArrayList<JournalModel> items;
private Context mContext;
....

then create your Filter class:

private class JournalFilter extends Filter{

    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults result = new FilterResults();
        List<JournalModel> allJournals = getAllJournals();
        if(constraint == null || constraint.length() == 0){

            result.values = allJournals;
            result.count = allJournals.size();
        }else{
            ArrayList<JournalModel> filteredList = new ArrayList<JournalModel>();
            for(JournalModel j: allJournals){
                if(j.source.title.contains(constraint))
                    filteredList.add(j);
            }
            result.values = filteredList;
            result.count = filteredList.size();
        }

        return result;
    }
    @SuppressWarnings("unchecked")
    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        if (results.count == 0) {
            notifyDataSetInvalidated();
        } else {
            items = (ArrayList<JournalModel>) results.values;
            notifyDataSetChanged();
        }
    }

}

this way, your adapter is Filterable, you can pass filter item to adapter's filter and do the work. I hope this will be helpful.

  <select ng-model="selectedCar" ><option ng-repeat="car in cars "  value="{{car.model}}">{{car.model}}</option></select>
<script>var app = angular.module('myApp', []);app.controller('myCtrl', function($scope) { $scope.cars = [{model : "Ford Mustang", color : "red"}, {model : "Fiat 500", color : "white"},{model : "Volvo XC90", color : "black"}];
$scope.selectedCar=$scope.cars[0].model ;});

I think I would go with @beberlei's suggestion of using proxy methods. What you can do to make this process simpler is to define two interfaces:

interface AlbumInterface {
    public function getAlbumTitle();
    public function getTracklist();
}

interface TrackInterface {
    public function getTrackTitle();
    public function getTrackDuration();
}

Then, both your Album and your Track can implement them, while the AlbumTrackReference can still implement both, as following:

class Album implements AlbumInterface {
    // implementation
}

class Track implements TrackInterface {
    // implementation
}

/** @Entity whatever */
class AlbumTrackReference implements AlbumInterface, TrackInterface
{
    public function getTrackTitle()
    {
        return $this->track->getTrackTitle();
    }

    public function getTrackDuration()
    {
        return $this->track->getTrackDuration();
    }

    public function getAlbumTitle()
    {
        return $this->album->getAlbumTitle();
    }

    public function getTrackList()
    {
        return $this->album->getTrackList();
    }
}

This way, by removing your logic that is directly referencing a Track or an Album, and just replacing it so that it uses a TrackInterface or AlbumInterface, you get to use your AlbumTrackReference in any possible case. What you will need is to differentiate the methods between the interfaces a bit.

This won't differentiate the DQL nor the Repository logic, but your services will just ignore the fact that you're passing an Album or an AlbumTrackReference, or a Track or an AlbumTrackReference because you've hidden everything behind an interface :)

Hope this helps!

Not sure about how other people solve this problem or whether Bootstrap has any configuration for this.

I found this thread that provides a solution:

https://github.com/twbs/bootstrap/issues/1411

One of the post suggests the use of

<ul class="dropdown-menu" style="right: 0; left: auto;">

I tested and it works.

Hope to know whether Bootstrap provides config for doing this, not via the above css.

Cheers.

Parent: Car
Child: Figo
Car c1 = new Figo();

=====
Upcasting:-
Method: Object c1 will refer to Methods of Class (Figo - Method must be overridden) because class "Figo" is specified with "new".
Instance Variable: Object c1 will refer to instance variable of Declaration Class ("Car").

When Declaration class is parent and object is created of child then implicit casting happens which is "Upcasting".

======
Downcasting:-
Figo f1 = (Figo) c1; //
Method: Object f1 will refer to Method of Class (figo) as initial object c1 is created with class "Figo". but once down casting is done, methods which are only present in class "Figo" can also be referred by variable f1.
Instance Variable: Object f1 will not refer to instance variable of Declaration class of object c1 (declaration class for c1 is CAR) but with down casting it will refer to instance variables of class Figo.

======
Use: When Object is of Child Class and declaration class is Parent and Child class wants to access Instance variable of it's own class and not of parent class then it can be done with "Downcasting".

Encapsulate hides variables or some implementation that may be changed so often in a class to prevent outsiders access it directly. They must access it via getter and setter methods.

Abstraction is used to hiding something too but in a higher degree(class, interface). Clients use an abstract class(or interface) do not care about who or which it was, they just need to know what it can do.

I just edited my iPhone's 'hosts' file successfully (on Jailbroken iOS 4.0).

• Installed OpenSSH onto iPhone via Cydia
• Using a SFTP client like FileZilla on my computer, I connected to my iPhone
  • Address: [use your phone's IP address or hostname, eg. simophone.local]
  • Username: root
  • Password: alpine
• Located the /etc/hosts file
• Made a backup on my computer (in case I want to revert my changes later)
• Edited the hosts file in a decent text editor (such as Notepad++). See here for an explanation of the hosts file.
• Uploaded the changes, overwriting the hosts file on the iPhone

The phone does cache some webpages and DNS queries, so a reboot or clearing the cache may help. Hope that helps someone.

A list of the few remaining cosmetic and packaging differences between Oracle JDK 11 and OpenJDK 11 can be found in this blog post:

https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later

In short:

• Oracle JDK 11 emits a warning when using the -XX:+UnlockCommercialFeatures option,
• it can be configured to provide usage log data to the “Advanced Management Console” tool,
• it has always required third party cryptographic providers to be signed by a known certificate,
• it will continue to include installers, branding and JRE packaging,
• while the javac --release command behaves slightly differently for the Java 9 and Java 10 targets, and
• the output of the java --version and java -fullversion commands will distinguish Oracle JDK builds from OpenJDK builds.

In C#, a base class' constructor runs before the derived class' constructor, so any instance fields that a derived class might use in the possibly-overridden virtual member are not initialized yet.

Do note that this is just a warning to make you pay attention and make sure it's all-right. There are actual use-cases for this scenario, you just have to document the behavior of the virtual member that it can not use any instance fields declared in a derived class below where the constructor calling it is.

In my case function eval() works very good. Below I generate 10 variables and assign them 10 values.

lhs <- rnorm(10)
rhs <- paste("perf.a", 1:10, "<-", lhs, sep="")
eval(parse(text=rhs))

You need to concatenate your string.

document.getElementById(tabName).style.backgroundImage = 'url(buttons/' + imagePrefix + '.png)';

The way you had it, it's just making 1 long string and not actually interpreting imagePrefix.

I would even suggest creating the string separate:

function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
    var urlString = 'url(buttons/' + imagePrefix + '.png)';
    document.getElementById(tabName).style.backgroundImage =  urlString;
}

As mentioned by David Thomas below, you can ditch the double quotes in your string. Here is a little article to get a better idea of how strings and quotes/double quotes are related: http://www.quirksmode.org/js/strings.html

Adding .Date to your date sets it to midnight (00:00).

MyDate.Date

Note The equivavalent SQL is CONVERT(DATETIME, CONVERT(DATE, @MyDate))

What makes this method so good is that it's both quick to type and easy to read. A bonus is that there is no conversion from strings.

I.e. To set today's date to 23:30, use:

DateTime.Now.Date.AddHours(23).AddMinutes(30)

You can of course replace DateTime.Now or MyDate with any date of your choice.

Using Flexbox:

HTML:

<div class="container">
  <img src="http://lorempixel.com/400/200" />
</div>

CSS:

.container {
  height: 500px;
  display: flex;
  justify-content: center; /* horizontal center */
  align-items: center;     /* vertical center */
}

FWIW., the latest version of brew is at protobuf 3.0, and doesn't include any formulae for the older versions. This is somewhat "inconvenient".

While protobuf may be compatible at the wire level, it is absolutely not compatible at the level of generated java classes: you can't use .class files generated with protoc 2.4 with the protobuf-2.5 JAR, etc. etc. This is why updating protobuf versions is such a sensitive topic in the Hadoop stack: it invariably requires coordination across different projects, and is traumatic enough that nobody likes to do it.

I use Git on multiple platforms, and I like to use the same Git settings on all of them. (In fact, I have all my configuration files under release control with Git, and put a Git repository clone on each machine.) The solution I came up with is this:

I set my editor to giteditor

git config --global core.editor giteditor

Then I create a symbolic link called giteditor which is in my PATH. (I have a personal bin directory, but anywhere in the PATH works.) That link points to my current editor of choice. On different machines and different platforms, I use different editors, so this means that I don't have to change my universal Git configuration (.gitconfig), just the link that giteditor points to.

Symbolic links are handled by every operating system I know of, though they may use different commands. For Linux, you use ln -s. For Windows, you use the cmd built-in mklink. They have different syntaxes (which you should look up), but it all works the same way, really.

You can use the SimpleDateFormat class:

SimpleDateFormat s = new SimpleDateFormat("ddMMyyyyhhmmss");
String format = s.format(new Date());

I believe this snippet will also be helpful in a situation where the dates comparison spans more than two entries.

static final int COMPARE_EARLIEST = 0;

static final int COMPARE_MOST_RECENT = 1;


public LocalDate getTargetDate(List<LocalDate> datesList, int comparatorType) { 
   LocalDate refDate = null;
   switch(comparatorType)
   {
       case COMPARE_EARLIEST:         
       //returns the most earliest of the date entries
          refDate = (LocalDate) datesList.stream().min(Comparator.comparing(item -> 
                      item.toDateTimeAtCurrentTime())).get();
          break;

       case COMPARE_MOST_RECENT:
          //returns the most recent of the date entries 
          refDate = (LocalDate) datesList.stream().max(Comparator.comparing(item -> 
                    item.toDateTimeAtCurrentTime())).get();
          break;
   }

   return refDate;
}

The permament pool contains everything that is not your application data, but rather things required for the VM: typically it contains interned strings, the byte code of defined classes, but also other "not yours" pieces of data.

I usually do what SBJ proposes, but the other way around. I simply find it easier to understand my code by checking for positive results instead of double negatives. You might be asking for how to check for empty EdiTexts, but what you really want to know is if it has any content and not that it is not empty.

Like so:

private boolean hasContent(EditText et) {
    // Always assume false until proven otherwise
    boolean bHasContent = false; 

    if (et.getText().toString().trim().length() > 0) {
        // Got content
        bHasContent = true;
    }
    return bHasContent;
}

As SBJ I prefer to return "has no content" (or false) as default to avoid exceptions because I borked my content-check. That way you will be absolutely certain that a true has been "approved" by your checks.

I also think the if calling it looks a bit cleaner as well:

if (hasContent(myEditText)) {
// Act upon content
} else {
// Got no content!
}

It is very much dependent on preference, but i find this easier to read. :)

The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.

According to this Google blogpost:

It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.

When referencing the mipmap- folders ensure you are using the following reference:

android:icon="@mipmap/ic_launcher"

The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

I know that this is the wrong time to be answering this question but i just thought of something

i know it might be stressful but atleast it might still work

Now the trick is to create a lot of server side encoding scripts, they have to be decodable(for example a script that replaces all vowels with numbers and add the letter 'a' to every consonant so that the word 'bat' becomes ba1ta) then create a script that will randomize between the encoding scripts and create a cookie with the name of the encoding script being used (quick tip: try not to use the actual name of the encoding script for the cookie for example if our cookie is name 'encoding_script_being_used' and the randomizing script chooses an encoding script named MD10 try not to use MD10 as the value of the cookie but 'encoding_script4567656' just to prevent guessing) then after the cookie has been created another script will check for the cookie named 'encoding_script_being_used' and get the value, then it will determine what encoding script is being used.

Now the reason for randomizing between the encoding scripts was that the server side language will randomize which script to use to decode your javascript.js and then create a session or cookie to know which encoding scripts was used then the server side language will also encode your javascript .js and put it as a cookie

so people can't steal your code

but i would not advise this because

1. it is a long process
2. It is too stressful

String inputstr = "abcd: efg: 1006746"
int startindex = inputstr.length() - 10;
String outputtendigitstr = inputstr.substring(startindex);

Make sure you check string length is more than 10.

If you find the String you are searching for, you can go on for the length of that string (if in case you search aa in aaaa you consider it 2 times).

int c=0;
String found="male cat";
 for(int j=0; j<text.length();j++){
     if(text.contains(found)){
         c+=1;
         j+=found.length()-1;
     }
 }
 System.out.println("counter="+c);

Some may want to simply suppress the warning:

class SupressSettingWithCopyWarning:
    def __enter__(self):
        pd.options.mode.chained_assignment = None

    def __exit__(self, *args):
        pd.options.mode.chained_assignment = 'warn'

with SupressSettingWithCopyWarning():
    #code that produces warning

There are already very good answers here, but in some other cases (not this in particular) using map could be the "only" solution.

Specially when we want to use regexps, other than the standard ones.

For this case it would look like this:

 $('.myClass').filter(function(index, elem) {
    var jElem = $(elem);

    return jElem.closest('#Create').length > 0 || 
           jElem.closest('#Edit').length > 0;

}).plugin(...);

As I said before, here this solution could be useless, but for further problems, is a very good option

Python 3:

import urllib.request

wp = urllib.request.urlopen("http://google.com")
pw = wp.read()
print(pw)

Python 2:

import urllib
import sys

wp = urllib.urlopen("http://google.com")
for line in wp:
    sys.stdout.write(line)

While I have tested both the Codes in respective versions.

You have to add the following dependency to your build:

<dependency>
    <groupId>org.openrdf.sesame</groupId>
    <artifactId>sesame-rio-api</artifactId>
    <version>2.7.2</version>
</dependency>

Furthermore i would suggest to take a deep look into the documentation about how to use the lib.

The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:

XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
                    where xml2.Element("ID").Value == variable
                    select xml2).FirstOrDefault();

This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

navigate to the folder where you have installed your kibana if you have used yum to install kibana it will be placed in following location by default

/usr/share/kibana

then use the following command

bin/kibana --version

For creating a console-based UI, you can use gui.cs. It is open-source (from Miguel de Icaza, creator of Xamarin), and runs on .NET Core on Windows, Linux, and macOS.

It has the following components:

• Buttons
• Labels
• Text entry
• Text view
• Time editing field
• Radio buttons
• Checkboxes
• Dialog boxes
  • Message boxes
• Windows
• Menus
• ListViews
• Frames
• ProgressBars
• Scroll views and Scrollbars
• Hexadecimal viewer/editor (HexView)

In modern browsers (IE8, Firefox, Chrome, Opera, Safari) you can use querySelector():

function test(el){
  el.querySelector("#child").style.display = "none";
}

For older browsers (<=IE7), you would have to use some sort of library, such as Sizzle or a framework, such as jQuery, to work with selectors.

As mentioned, IDs are supposed to be unique within a document, so it's easiest to just use document.getElementById("child").

This answer is written to show just how trivial it is to bypass poorly written PHP user-validation code, how (and using what) these attacks work and how to replace the old MySQL functions with a secure prepared statement - and basically, why StackOverflow users (probably with a lot of rep) are barking at new users asking questions to improve their code.

First off, please feel free to create this test mysql database (I have called mine prep):

mysql> create table users(
    -> id int(2) primary key auto_increment,
    -> userid tinytext,
    -> pass tinytext);
Query OK, 0 rows affected (0.05 sec)

mysql> insert into users values(null, 'Fluffeh', 'mypass');
Query OK, 1 row affected (0.04 sec)

mysql> create user 'prepared'@'localhost' identified by 'example';
Query OK, 0 rows affected (0.01 sec)

mysql> grant all privileges on prep.* to 'prepared'@'localhost' with grant option;
Query OK, 0 rows affected (0.00 sec)

With that done, we can move to our PHP code.

Lets assume the following script is the verification process for an admin on a website (simplified but working if you copy and use it for testing):

<?php 

    if(!empty($_POST['user']))
    {
        $user=$_POST['user'];
    }   
    else
    {
        $user='bob';
    }
    if(!empty($_POST['pass']))
    {
        $pass=$_POST['pass'];
    }
    else
    {
        $pass='bob';
    }

    $database='prep';
    $link=mysql_connect('localhost', 'prepared', 'example');
    mysql_select_db($database) or die( "Unable to select database");

    $sql="select id, userid, pass from users where userid='$user' and pass='$pass'";
    //echo $sql."<br><br>";
    $result=mysql_query($sql);
    $isAdmin=false;
    while ($row = mysql_fetch_assoc($result)) {
        echo "My id is ".$row['id']." and my username is ".$row['userid']." and lastly, my password is ".$row['pass']."<br>";
        $isAdmin=true;
        // We have correctly matched the Username and Password
        // Lets give this person full access
    }
    if($isAdmin)
    {
        echo "The check passed. We have a verified admin!<br>";
    }
    else
    {
        echo "You could not be verified. Please try again...<br>";
    }
    mysql_close($link);

?>

<form name="exploited" method='post'>
    User: <input type='text' name='user'><br>
    Pass: <input type='text' name='pass'><br>
    <input type='submit'>
</form>

Seems legit enough at first glance.

The user has to enter a login and password, right?

Brilliant, not enter in the following:

user: bob
pass: somePass

and submit it.

The output is as follows:

You could not be verified. Please try again...

Super! Working as expected, now lets try the actual username and password:

user: Fluffeh
pass: mypass

Amazing! Hi-fives all round, the code correctly verified an admin. It's perfect!

Well, not really. Lets say the user is a clever little person. Lets say the person is me.

Enter in the following:

user: bob
pass: n' or 1=1 or 'm=m

And the output is:

The check passed. We have a verified admin!

Congrats, you just allowed me to enter your super-protected admins only section with me entering a false username and a false password. Seriously, if you don't believe me, create the database with the code I provided, and run this PHP code - which at glance REALLY does seem to verify the username and password rather nicely.

So, in answer, THAT IS WHY YOU ARE BEING YELLED AT.

So, lets have a look at what went wrong, and why I just got into your super-admin-only-bat-cave. I took a guess and assumed that you weren't being careful with your inputs and simply passed them to the database directly. I constructed the input in a way tht would CHANGE the query that you were actually running. So, what was it supposed to be, and what did it end up being?

select id, userid, pass from users where userid='$user' and pass='$pass'

That's the query, but when we replace the variables with the actual inputs that we used, we get the following:

select id, userid, pass from users where userid='bob' and pass='n' or 1=1 or 'm=m'

See how I constructed my "password" so that it would first close the single quote around the password, then introduce a completely new comparison? Then just for safety, I added another "string" so that the single quote would get closed as expected in the code we originally had.

However, this isn't about folks yelling at you now, this is about showing you how to make your code more secure.

Okay, so what went wrong, and how can we fix it?

This is a classic SQL injection attack. One of the simplest for that matter. On the scale of attack vectors, this is a toddler attacking a tank - and winning.

So, how do we protect your sacred admin section and make it nice and secure? The first thing to do will be to stop using those really old and deprecated mysql_* functions. I know, you followed a tutorial you found online and it works, but it's old, it's outdated and in the space of a few minutes, I have just broken past it without so much as breaking a sweat.

Now, you have the better options of using mysqli_ or PDO. I am personally a big fan of PDO, so I will be using PDO in the rest of this answer. There are pro's and con's, but personally I find that the pro's far outweigh the con's. It's portable across multiple database engines - whether you are using MySQL or Oracle or just about bloody anything - just by changing the connection string, it has all the fancy features we want to use and it is nice and clean. I like clean.

Now, lets have a look at that code again, this time written using a PDO object:

<?php 

    if(!empty($_POST['user']))
    {
        $user=$_POST['user'];
    }   
    else
    {
        $user='bob';
    }
    if(!empty($_POST['pass']))
    {
        $pass=$_POST['pass'];
    }
    else
    {
        $pass='bob';
    }
    $isAdmin=false;

    $database='prep';
    $pdo=new PDO ('mysql:host=localhost;dbname=prep', 'prepared', 'example');
    $sql="select id, userid, pass from users where userid=:user and pass=:password";
    $myPDO = $pdo->prepare($sql, array(PDO::ATTR_CURSOR => PDO::CURSOR_FWDONLY));
    if($myPDO->execute(array(':user' => $user, ':password' => $pass)))
    {
        while($row=$myPDO->fetch(PDO::FETCH_ASSOC))
        {
            echo "My id is ".$row['id']." and my username is ".$row['userid']." and lastly, my password is ".$row['pass']."<br>";
            $isAdmin=true;
            // We have correctly matched the Username and Password
            // Lets give this person full access
        }
    }

    if($isAdmin)
    {
        echo "The check passed. We have a verified admin!<br>";
    }
    else
    {
        echo "You could not be verified. Please try again...<br>";
    }

?>

<form name="exploited" method='post'>
    User: <input type='text' name='user'><br>
    Pass: <input type='text' name='pass'><br>
    <input type='submit'>
</form>

The major differences are that there are no more mysql_* functions. It's all done via a PDO object, secondly, it is using a prepared statement. Now, what's a prepred statement you ask? It's a way to tell the database ahead of running a query, what the query is that we are going to run. In this case, we tell the database: "Hi, I am going to run a select statement wanting id, userid and pass from the table users where the userid is a variable and the pass is also a variable.".

Then, in the execute statement, we pass the database an array with all the variables that it now expects.

The results are fantastic. Lets try those username and password combinations from before again:

user: bob
pass: somePass

User wasn't verified. Awesome.

How about:

user: Fluffeh
pass: mypass

Oh, I just got a little excited, it worked: The check passed. We have a verified admin!

Now, lets try the data that a clever chap would enter to try to get past our little verification system:

user: bob
pass: n' or 1=1 or 'm=m

This time, we get the following:

You could not be verified. Please try again...

This is why you are being yelled at when posting questions - it's because people can see that your code can be bypassed wihout even trying. Please, do use this question and answer to improve your code, to make it more secure and to use functions that are current.

Lastly, this isn't to say that this is PERFECT code. There are many more things that you could do to improve it, use hashed passwords for example, ensure that when you store sensetive information in the database, you don't store it in plain text, have multiple levels of verification - but really, if you just change your old injection prone code to this, you will be WELL along the way to writing good code - and the fact that you have gotten this far and are still reading gives me a sense of hope that you will not only implement this type of code when writing your websites and applications, but that you might go out and research those other things I just mentioned - and more. Write the best code you can, not the most basic code that barely functions.

while (fscanf(input,"%s",arr) != EOF && count!=7) {
  len=strlen(arr); 
  count++; 
}

First of all, the indexes will be from 0 to 4. Programming languages start counting from 0; don't forget that or you will come across an index out of bounds exception. All you need in the for loop is a variable counting from 0 to 4 like so:

for x in range(0, 5):

Keep in mind that I wrote 0 to 5 because the loop stops one number before the max. :)

To get the value of an index use

list[index]

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

See the output of the two different commands:

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

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

python3 -c "import sys; print(sys.path)"

['', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']

Both commands were executed on my Ubuntu 18.04 machine.

Normal ways would be Integer.toString(i) or String.valueOf(i).

int i = 5;
String strI = String.valueOf(i);

Or

int aInt = 1;    
String aString = Integer.toString(aInt);

Stealth Change in VS 2010 and .NET 4.0 and Later

No public installers with the RunInstallerAttribute.Yes attribute could be found

There is an alias change or compiler cleanup in .NET that may reveal this little tweak for your specific case.

If you have the following code …

RunInstaller(true)   // old alias  

You may need to update it to

RunInstallerAttribute(true)  // new property spelling

It is like an alias changed under the covers at compile time or at runtime and you will get this error behavior. The above explicit change to RunInstallerAttribute(true) fixed it in all of our install scenarios on all machines.

After you add project or service installer then check for the “old” RunInstaller(true) and change it to the new RunInstallerAttribute(true)

Try this:

public class Team
{
    public int TeamId { get; set;} 
    public string Name { get; set; }

    public virtual ICollection<Match> HomeMatches { get; set; }
    public virtual ICollection<Match> AwayMatches { get; set; }
}

public class Match
{
    public int MatchId { get; set; }

    public int HomeTeamId { get; set; }
    public int GuestTeamId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public virtual Team HomeTeam { get; set; }
    public virtual Team GuestTeam { get; set; }
}


public class Context : DbContext
{
    ...

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Match>()
                    .HasRequired(m => m.HomeTeam)
                    .WithMany(t => t.HomeMatches)
                    .HasForeignKey(m => m.HomeTeamId)
                    .WillCascadeOnDelete(false);

        modelBuilder.Entity<Match>()
                    .HasRequired(m => m.GuestTeam)
                    .WithMany(t => t.AwayMatches)
                    .HasForeignKey(m => m.GuestTeamId)
                    .WillCascadeOnDelete(false);
    }
}

Primary keys are mapped by default convention. Team must have two collection of matches. You can't have single collection referenced by two FKs. Match is mapped without cascading delete because it doesn't work in these self referencing many-to-many.

Ryan Farley has a great post about this in his blog, including all the reasons why not to write back into web.config files: Writing to Your .NET Application's Config File

You can get first element via index selector:

$('div.second div:eq(0)')

Code: http://jsfiddle.net/RX46D/

for users running VS2013

In windows 10.

Check if apache service is running. since it gets replaced with World wide web service.

run netstat -n to check this.

stop the service. start apache. restart the service.

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

In general you put your translations in resource files, e.g. resources.resx.

Each specific culture has a different name, e.g. resources.nl.resx, resources.fr.resx, resources.de.resx, …

Now the most important part of a solution is to maintain your translations. In Visual Studio install the Microsoft MAT tool: Multilingual App Toolkit (MAT). Works with winforms, wpf, asp.net (core), uwp, …

In general, e.g. for a WPF solution, in the WPF project

• Install the Microsoft MAT extension for Visual Studio.
• In the Solution Explorer, navigate to your Project > Properties > AssemblyInfo.cs
• Add in AssemblyInfo.cs your default, neutral language (in my case English): [assembly: System.Resources.NeutralResourcesLanguage("en")]
• Select your project in Solution Explorer and in Visual Studio, from the top menu, click "Tools" > "Multilingual App Toolkit" > "Enable Selection", to enable MAT for the project.
  • Now Right mouse click on the project in Solution Explorer, select "Multilingual App Toolkit" > "Add translation languages…" and select the language that you want to add translations for. e.g. Dutch.

What you will see is that a new folder will be created, called "MultilingualResources" containing a ....nl.xlf file.

The only thing you now have to do is:

1. add your translation to your default resources.resx file (in my case English)
2. Translate by clicking the .xlf file (NOT the .resx file) as the .xlf files will generate/update the .resx files.

(the .xlf files should open with the "Multilingual Editor", if this is not the case, right mouse click on the .xlf file, select "Open With…" and select "Multilingual Editor".

Have fun! now you can also see what has not been translated, export translations in xlf to external translation companies, import them again, recycle translations from other projects etc...

Just use this constructor of List<T>. It accepts any IEnumerable<T> as an argument.

string[] arr = ...
List<string> list = new List<string>(arr);

My Code Is Very Easy To Understand

var year = 2015;
var LeapYear = year % 4;

if (LeapYear==0) {
    alert("This is Leap Year");
} else {
    alert("This is not leap year");
}

Android SDK Manager

sudo snap install androidsdk

Usage

You can use the sdkmanager to perform the following tasks.

List installed and available packages

androidsdk --list [options]

Install packages

androidsdk packages [options]

The packages argument is an SDK-style path as shown with the --list command, wrapped in quotes (for example, "build-tools;29.0.0" or "platforms;android-28"). You can pass multiple package paths, separated with a space, but they must each be wrapped in their own set of quotes.

For example, here's how to install the latest platform tools (which includes adb and fastboot) and the SDK tools for API level 28:

androidsdk "platform-tools" "platforms;android-28"

Alternatively, you can pass a text file that specifies all packages:

androidsdk --package_file=package_file [options]

The package_file argument is the location of a text file in which each line is an SDK-style path of a package to install (without quotes).

To uninstall, simply add the --uninstall flag:

androidsdk --uninstall packages [options]
androidsdk --uninstall --package_file=package_file [options]

Update all installed packages

androidsdk --update [options]

Note

androidsdk it is snap wraper of sdkmanager all options of sdkmanager work with androidsdk

Location of installed android sdk files : /home/user/AndroidSDK

See all sdkmanager options in google documentation

Swift 3/4

You can use the below extension for your convenience.

Usage inside a ViewController:

showInputDialog(title: "Add number",
                subtitle: "Please enter the new number below.",
                actionTitle: "Add",
                cancelTitle: "Cancel",
                inputPlaceholder: "New number",
                inputKeyboardType: .numberPad)
{ (input:String?) in
    print("The new number is \(input ?? "")")
}

The extension code:

extension UIViewController {
    func showInputDialog(title:String? = nil,
                         subtitle:String? = nil,
                         actionTitle:String? = "Add",
                         cancelTitle:String? = "Cancel",
                         inputPlaceholder:String? = nil,
                         inputKeyboardType:UIKeyboardType = UIKeyboardType.default,
                         cancelHandler: ((UIAlertAction) -> Swift.Void)? = nil,
                         actionHandler: ((_ text: String?) -> Void)? = nil) {

        let alert = UIAlertController(title: title, message: subtitle, preferredStyle: .alert)
        alert.addTextField { (textField:UITextField) in
            textField.placeholder = inputPlaceholder
            textField.keyboardType = inputKeyboardType
        }
        alert.addAction(UIAlertAction(title: actionTitle, style: .default, handler: { (action:UIAlertAction) in
            guard let textField =  alert.textFields?.first else {
                actionHandler?(nil)
                return
            }
            actionHandler?(textField.text)
        }))
        alert.addAction(UIAlertAction(title: cancelTitle, style: .cancel, handler: cancelHandler))

        self.present(alert, animated: true, completion: nil)
    }
}

Let me clarify what you're talking about: you want to test Foo in a testcase, which calls external method uses_some_other_method. Instead of calling the actual method, you want to mock the return value.

class Foo:
    def method_1():
       results = uses_some_other_method()
    def method_n():
       results = uses_some_other_method()

Suppose the above code is in foo.py and uses_some_other_method is defined in module bar.py. Here is the unittest:

import unittest
import mock

from foo import Foo


class TestFoo(unittest.TestCase):

    def setup(self):
        self.foo = Foo()

    @mock.patch('foo.uses_some_other_method')
    def test_method_1(self, mock_method):
        mock_method.return_value = 3
        self.foo.method_1(*args, **kwargs)

        mock_method.assert_called_with(*args, **kwargs)

If you want to change the return value every time you passed in different arguments, mock provides side_effect.

The reason why most use HashSet is that the operations are (on average) O(1) instead of O(log n). If the set contains standard items you will not be "messing around with hash functions" as that has been done for you. If the set contains custom classes, you have to implement hashCode to use HashSet (although Effective Java shows how), but if you use a TreeSet you have to make it Comparable or supply a Comparator. This can be a problem if the class does not have a particular order.

I have sometimes used TreeSet (or actually TreeMap) for very small sets/maps (< 10 items) although I have not checked to see if there is any real gain in doing so. For large sets the difference can be considerable.

Now if you need the sorted, then TreeSet is appropriate, although even then if updates are frequent and the need for a sorted result is infrequent, sometimes copying the contents to a list or an array and sorting them can be faster.

The named ones are all raster graphics, but beside that don't forget the more and more important vectorgraphics. There are compressed and uncompressed types (in a more or less way), but they're all lossless. Most important are:

• SVG / SVGZ
• EPS
• EMF / (WMF)

Remote scenario. But if you're trying to run tests in a rails app, and you get something like

"ActiveRecord::StatementInvalid: PG::ObjectInUse: ERROR: database "myapp_test" is being accessed by other users DETAIL: There is 1 other session using the database."

Make sure you close pgAdmin or any other postgres GUI tools before running tests.

If you want to compare based on the commit messages, you can do the following:

git fetch
git log --oneline origin/master | cut -d' ' -f2- > master_log
git log --oneline origin/branch-X | cut -d' ' -f2- > branchx_log
diff <(sort master_log) <(sort branchx_log)

If you want to select only decimal numbers use this WHERE clause:

    (CAST(RIGHT(Myfield, LEN( Myfield)-CHARINDEX('.',Myfield)+1 ) AS FLOAT)) <> 0

If you want a clear list you can sort by decimal/integer:

    CASE WHEN 0 = CAST(RIGHT(Myfield, LEN( Myfield)-CHARINDEX('.',Myfield)+1 ) AS FLOAT) THEN 'Integer' ELSE 'Decimal' END AS Type

Javascript Variables

You can start a variable with any letter, $, or _ character. As long as it doesn't start with a number, you can include numbers as well.

Start: [a-z], $, _

Contain: [a-z], [0-9], $, _

jQuery

You can use _ for your library so that it will stand side-by-side with jQuery. However, there is a configuration you can set so that jQuery will not use $. It will instead use jQuery. To do this, simply set:

jQuery.noConflict();

This page explains how to do this.

Python does not add the current directory to sys.path, but rather the directory that the script is in. Add /home/bodacydo/work/project to either sys.path or $PYTHONPATH.

The only way I could solve was by adding my users python dir to myapp.wsgi file. As an example:

sys.path.append('/home/deployer/anaconda3/lib/python3.5/site-packages')

I guess that if you install the packages in the global enviroment, you should have no problem, but I had my python packages installed as user.

In Swift5 and Xcode 10

self.navigationItem.title = "your name"
let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white]
navigationController?.navigationBar.titleTextAttributes = textAttributes

This worked for me

Function round_Up_To_Int(n As Double)
    If Math.Round(n) = n Or Math.Round(n) = 0 Then
        round_Up_To_Int = Math.Round(n)
    Else: round_Up_To_Int = Math.Round(n + 0.5)
    End If
End Function

Example:

<songs>
<song dateplayed="2011-07-24 19:40:26">
    <title>I left my heart on Europa</title>
    <artist>Ship of Nomads</artist>
</song>
<song dateplayed="2011-07-24 19:27:42">
    <title>Oh Ganymede</title>
    <artist>Beefachanga</artist>
</song>
<song dateplayed="2011-07-24 19:23:50">
    <title>Kallichore</title>
    <artist>Jewitt K. Sheppard</artist>
</song>

then:

<?php
$mysongs = simplexml_load_file('songs.xml');
echo $mysongs->song[0]->artist;
?>

Output on your browser: Ship of Nomads

I have used the discover method and an overloading of load_tests to achieve this result in a (minimal, I think) number lines of code:

def load_tests(loader, tests, pattern):
''' Discover and load all unit tests in all files named ``*_test.py`` in ``./src/``
'''
    suite = TestSuite()
    for all_test_suite in unittest.defaultTestLoader.discover('src', pattern='*_tests.py'):
        for test_suite in all_test_suite:
            suite.addTests(test_suite)
    return suite

if __name__ == '__main__':
    unittest.main()

Execution on fives something like

ESLint 2.x experimentally supports ObjectRestSpread syntax, you can enable it by adding the following to your .eslintrc: docs

"parserOptions": {
  "ecmaVersion": 6,
  "ecmaFeatures": {
    "experimentalObjectRestSpread": true
  }
},

ESLint 1.x doesn't natively support the spread operator, one way to get around this is using the babel-eslint parser. The latest installation and usage instructions are on the project readme.

Override onDestroy of the Activity and Dismiss your Dialog & make it null

I recommend you to check docs section dedicated for Loop to get better understanding. Some snippet taken from there:

We have two calls that are similar as far as users are concerned, but their names are confusing.

• process.nextTick() fires immediately on the same phase

• setImmediate() fires on the following iteration or 'tick' of the
  event loop

In essence, the names should be swapped. process.nextTick() fires more immediately than setImmediate(), but this is an artifact of the past which is unlikely to change.

Programmers who don't code in their spare time for fun will never become as good as those that do.

I think even the smartest and most talented people will never become truly good programmers unless they treat it as more than a job. Meaning that they do little projects on the side, or just mess with lots of different languages and ideas in their spare time.

(Note: I'm not saying good programmers do nothing else than programming, but they do more than program from 9 to 5)

First get the text from edit text view

edittext.getText().toString()

and Store the obtained text in a string, say value.

value = edittext.getText().toString()

Then set value as the text for textview.

textview.setText(value)

Using ERRORLEVEL when it's available is the easiest option. However, if you're calling an external program to perform some task, and it doesn't return proper codes, you can pipe the output to 'find' and check the errorlevel from that.

c:\mypath\myexe.exe | find "ERROR" >nul2>nul
if not ERRORLEVEL 1 (
echo. Uh oh, something bad happened
exit /b 1
)

Or to give more info about what happened

c:\mypath\myexe.exe 2&1> myexe.log
find "Invalid File" "myexe.log" >nul2>nul && echo.Invalid File error in Myexe.exe && exit /b 1
find "Error 0x12345678" "myexe.log" >nul2>nul && echo.Myexe.exe was unable to contact server x && exit /b 1

1. Build a table of small primes, and check if they divide your input number.
2. If the number survived to 1, try pseudo primality tests with increasing basis. See Miller-Rabin primality test for example.
3. If your number survived to 2, you can conclude it is prime if it is below some well known bounds. Otherwise your answer will only be "probably prime". You will find some values for these bounds in the wiki page.

This CSS seems to work in Safari and Chrome:

div#div2
{
-webkit-transform:rotate(90deg); /* Chrome, Safari, Opera */
transform:rotate(90deg); /* Standard syntax */
}

and in the body:

<div id="div2"><img src="image.jpg"  ></div>

But this (and the .rotate90 example above) pushes the rotated image higher up on the page than if it were un-rotated. Not sure how to control placement of the image relative to text or other rotated images.

Use a for loop:

keys = ['firstKey', 'secondKey', 'thirdKey']
for key in keys:

   }
]

You can simply add onended="myFunction()" to your video tag.

<video onended="myFunction()">
  ...
  Your browser does not support the video tag.
</video>

<script type='text/javascript'>
  function myFunction(){
    console.log("The End.")
  }
</script>

the answers above doesn't work in my case. You need to specify utf-8 in meta tag

This post itself is not a direct answer to the question. What it is instead is a data-driven extensible benchmark that can be used to compare many of the answers (and variations of utilizing new features added in later, more modern, versions of Python) that have been posted to this question — and should therefore be helpful in determining which has the best performance.

In a few cases I've modified the code in the referenced answer to make it compatible with the benchmark framework.

First, here are the results for what currently are the latest versions of Python 2 & 3:

Watch out!

If you have several script tags and your're searching an information in tag attributes for example, you have to use .length property with a for loop because it isn't a simple array but an HTMLCollection object.

https://developer.mozilla.org/en/DOM/HTMLCollection

If you use the foreach statement for(var i in yourList) it will return proterties and methods of the HTMLCollection in most browsers!

var scriptTags = document.getElementsByTagName("script");

for(var i = 0; i < scriptTags.length; i++)
alert(i); // Will print all your elements index (you can get src attribute value using scriptTags[i].attributes[0].value)

for(var i in scriptTags)
alert(i); // Will print "length", "item" and "namedItem" in addition to your elements!

Even if getElementsByTagName should return a NodeList, most browser are returning an HTMLCollection: https://developer.mozilla.org/en/DOM/document.getElementsByTagName

Alternative by terminal with no permission

The pg documentation at NOTES say

The path will be interpreted relative to the working directory of the server process (normally the cluster's data directory), not the client's working directory.

So, gerally, using psql or any client, even in a local server, you have problems ... And, if you're expressing COPY command for other users, eg. at a Github README, the reader will have problems ...

The only way to express relative path with client permissions is using STDIN,

When STDIN or STDOUT is specified, data is transmitted via the connection between the client and the server.

as remembered here:

psql -h remotehost -d remote_mydb -U myuser -c \
   "copy mytable (column1, column2) from STDIN with delimiter as ','" \
   < ./relative_path/file.csv

I'm not sure about this, but give it a shot.

In your strings.xml define:

<string-array name="array_name">
<item>Array Item One</item>
<item>Array Item Two</item>
<item>Array Item Three</item>
</string-array>

In your layout:

<Spinner 
        android:id="@+id/spinner"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:drawSelectorOnTop="true"
        android:entries="@array/array_name"
    />

I've heard this doesn't always work on the designer, but it compiles fine.

In your case, you just need to remove the line breaks (<br> tags) between the elements - input elements are inline-block by default (in Chrome at least). (updated example).

<input type="radio" name="editList" value="always">Always
<input type="radio" name="editList" value="never">Never
<input type="radio" name="editList" value="costChange">Cost Change

I'd suggest using <label> elements, though. In doing so, clicking on the label will check the element too. Either associate the <label>'s for attribute with the <input>'s id: (example)

<input type="radio" name="editList" id="always" value="always"/>
<label for="always">Always</label>

<input type="radio" name="editList" id="never" value="never"/>
<label for="never">Never</label>

<input type="radio" name="editList" id="change" value="costChange"/>
<label for="change">Cost Change</label>

..or wrap the <label> elements around the <input> elements directly: (example)

<label>
    <input type="radio" name="editList" value="always"/>Always
</label>
<label>
    <input type="radio" name="editList" value="never"/>Never
</label>
<label>
    <input type="radio" name="editList" value="costChange"/>Cost Change
</label>

You can also get fancy and use the :checked pseudo class.

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

I've found this useful:

 select translate('your string','_0123456789','_') from dual

If the result is NULL, it's numeric (ignoring floating point numbers.)

However, I'm a bit baffled why the underscore is needed. Without it the following also returns null:

 select translate('s123','0123456789', '') from dual

There is also one of my favorite tricks - not perfect if the string contains stuff like "*" or "#":

 SELECT 'is a number' FROM dual WHERE UPPER('123') = LOWER('123')

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

First Add a Class called Win32.cs

public class Win32
{ 
    [DllImport("User32.Dll")]
    public static extern long SetCursorPos(int x, int y);

    [DllImport("User32.Dll")]
    public static extern bool ClientToScreen(IntPtr hWnd, ref POINT point);

    [StructLayout(LayoutKind.Sequential)]
    public struct POINT
    {
        public int x;
        public int y;

        public POINT(int X, int Y)
        {
            x = X;
            y = Y;
        }
    }
}

You can use it then like this:

Win32.POINT p = new Win32.POINT(xPos, yPos);

Win32.ClientToScreen(this.Handle, ref p);
Win32.SetCursorPos(p.x, p.y);

The Problem: you trying to create new container while in background container with same name is running and this situation causes conflicts.

The error would be like:

Cannot create continer for service X :Conflict. The name X is already in use by container abc123xyz. You have to remove ot delete (or rename) that container to be able to reuse that name.

Solution rename the service name in docker-compose.yml or delete the running container and rebuild it again (this solution related to Unix/Linux/macOS systems):

1. get all running containers sudo docker ps -a
2. get the specific container id
3. stop and remove the duplicated container / force remove it

sudo docker stop <container_id>
sudo docker rm <container_id>

or

sudo docker rm --force <container_id>

In my case, I was dealing with a file that was generated by hadoop on a linux box. When I tried to import to sql I had this issue. The fix wound up being to use the hex value for 'line feed' 0x0a. It also worked for bulk insert

bulk insert table from 'file' 
WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '0x0a')

I would use regular expression matching to sum over variables with certain pattern names. For example:

df <- df %>% mutate(sum1 = rowSums(.[grep("x[3-5]", names(.))], na.rm = TRUE),
                    sum_all = rowSums(.[grep("x", names(.))], na.rm = TRUE))

This way you can create more than one variable as a sum of certain group of variables of your data frame.

I know none of the above solutions is gonna work as I have remained stuck into this sort of issue a long time, finally resolved this issue after watching the issue very carefully, which is pointing that

Unable to resolve dependency for ':app@dexOptions/compileClasspath': Could not resolve project : library_Name.

You need to make a sure and double check if the class is residing there. This one thing will prove much helpful to many I guess because focusing on this point took me much closer to the solution. Now if nothing exists in that folder path you need to get the whole stuff like src folder build folder etc everything, copy that and paste it over there sync/rebuild project, if needed try invalidate and restart android studio. Hope so this will get you out of trouble as happend in my case.

Thanks

I found that using the Common Event described above works well and you could have the common event set up like this:

private void checkChanged(object sender, EventArgs e)
    {
        foreach (RadioButton r in yourPanel.Controls)
        {
            if (r.Checked)
                textBox.Text = r.Text;
        }
    }

Of course, then you can't have other controls in your panel that you use, but it's useful if you just have a separate panel for all your radio buttons (such as using a sub panel inside a group box or however you prefer to organize your controls)

The first thing you tried seems to work fine. Here is an example program.
Press the "Start" button at the top of this page to run it to see the output yourself.

import java.util.Arrays;

public class Foo{
    public static void main(String[] args) {
        String [] stringArray = {"ab", "aB", "c", "0", "2", "1Ad", "a10"};
        orderedGuests(stringArray);
    }

    public static void orderedGuests(String[] hotel)
    {
        Arrays.sort(hotel);
        System.out.println(Arrays.toString(hotel));
    }
}

Copying a string can be done two ways either copy the location a = "a" b = a or you can clone which means b wont get affected when a is changed which is done by a = 'a' b = a[:]

I waited a bit on @QuinnTaylor to update his answer, but since he didn't, here's the answer a bit more clearly and in a way that it will load on XCode7 (and perhaps greater). I used this in a Cocoa application, but it likely will work okay with an iOS application as well. Has no ARC errors.

Paste these two functions in the @implementation class you desire. In my case, I chose @implementation AppDelegate in my AppDelegate.mm or AppDelegate.m file.

- (NSString *) encryptString:(NSString*)plaintext withKey:(NSString*)key {
    NSData *data = [[plaintext dataUsingEncoding:NSUTF8StringEncoding] AES256EncryptWithKey:key];
    return [data base64EncodedStringWithOptions:kNilOptions];
}

- (NSString *) decryptString:(NSString *)ciphertext withKey:(NSString*)key {
    NSData *data = [[NSData alloc] initWithBase64EncodedString:ciphertext options:kNilOptions];
    return [[NSString alloc] initWithData:[data AES256DecryptWithKey:key] encoding:NSUTF8StringEncoding];
}

$tmp = array();
foreach (array_values($array) as $key => $value) {
    $tmp[$key+1] = $value;
}
$array = $tmp;

use

int and float are not iterable

The <center> element was deprecated because it defines the presentation of its contents — it does not describe its contents.

One method of centering is to set the margin-left and margin-right properties of the element to auto, and then set the parent element’s text-align property to center. This guarantees that the element will be centered in all modern browsers.

I am also still figuring out the internals of git, and have figured out this so far:

1. HEAD is a file in your .git/ directory that normally looks something like this:

% cat .git/HEAD
ref: refs/heads/master

2. refs/heads/master is itself a file that normally has the hash value of the latest commit:

% cat .git/refs/heads/master 
cbf01a8e629e8d884888f19ac203fa037acd901f

3. If you git checkout a remote branch that is ahead of your master, this may cause your HEAD file to be updated to contain the hash of the latest commit in the remote master:

% cat .git/HEAD
8e2c815f83231f85f067f19ed49723fd1dc023b7

This is called a detached HEAD. The remote master is ahead of your local master. When you do git submodule --remote myrepo to get the latest commit of your submodule, it will by default do a checkout, which will update HEAD. Since your current branch master is behind, HEAD becomes 'detached' from your current branch, so to speak.

OSX users can follow by Nicolay77 or mikkom that uses the mdbtools utility. You can install it via Homebrew. Just have your homebrew installed and then go

$ homebrew install mdbtools

Then create one of the scripts described by the guys and use it. I've used mikkom's one, converted all my mdb files into sql.

$ ./to_mysql.sh myfile.mdb > myfile.sql

(which btw contains more than 1 table)

For Translating the command to python refer below:-

1)Alternative of cat command is open refer this. Below is the sample

>>> f = open('workfile', 'r')
>>> print f

2)Alternative of grep command refer this

3)Alternative of Cut command refer this
