Pure-PHP implementation of Rijndael exists with phpseclib available as composer package and works on PHP 7.3 (tested by me).
There's a page on the phpseclib docs, which generates sample code after you input the basic variables (cipher, mode, key size, bit size). It outputs the following for Rijndael, ECB, 256, 256:
a code with mycrypt
$decoded = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, ENCRYPT_KEY, $term, MCRYPT_MODE_ECB);
works like this with the library
$rijndael = new \phpseclib\Crypt\Rijndael(\phpseclib\Crypt\Rijndael::MODE_ECB);
$rijndael->setKey(ENCRYPT_KEY);
$rijndael->setKeyLength(256);
$rijndael->disablePadding();
$rijndael->setBlockLength(256);
$decoded = $rijndael->decrypt($term);
* $term
was base64_decoded
fixed by setting GSSAPIAuthentication to no in /etc/ssh/sshd_config
I was using CommonCrypto to generate Hash through the code of MihaelIsaev/HMAC.swift from Easy to use Swift implementation of CommonCrypto HMAC. This implementation is without using Bridging-Header, with creation of Module file.
Now to use AESEncrypt and Decrypt, I directly added the functions inside "extension String {" in HAMC.swift.
func aesEncrypt(key:String, iv:String, options:Int = kCCOptionPKCS7Padding) -> String? {
if let keyData = key.dataUsingEncoding(NSUTF8StringEncoding),
data = self.dataUsingEncoding(NSUTF8StringEncoding),
cryptData = NSMutableData(length: Int((data.length)) + kCCBlockSizeAES128) {
let keyLength = size_t(kCCKeySizeAES128)
let operation: CCOperation = UInt32(kCCEncrypt)
let algoritm: CCAlgorithm = UInt32(kCCAlgorithmAES128)
let options: CCOptions = UInt32(options)
var numBytesEncrypted :size_t = 0
let cryptStatus = CCCrypt(operation,
algoritm,
options,
keyData.bytes, keyLength,
iv,
data.bytes, data.length,
cryptData.mutableBytes, cryptData.length,
&numBytesEncrypted)
if UInt32(cryptStatus) == UInt32(kCCSuccess) {
cryptData.length = Int(numBytesEncrypted)
let base64cryptString = cryptData.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)
return base64cryptString
}
else {
return nil
}
}
return nil
}
func aesDecrypt(key:String, iv:String, options:Int = kCCOptionPKCS7Padding) -> String? {
if let keyData = key.dataUsingEncoding(NSUTF8StringEncoding),
data = NSData(base64EncodedString: self, options: .IgnoreUnknownCharacters),
cryptData = NSMutableData(length: Int((data.length)) + kCCBlockSizeAES128) {
let keyLength = size_t(kCCKeySizeAES128)
let operation: CCOperation = UInt32(kCCDecrypt)
let algoritm: CCAlgorithm = UInt32(kCCAlgorithmAES128)
let options: CCOptions = UInt32(options)
var numBytesEncrypted :size_t = 0
let cryptStatus = CCCrypt(operation,
algoritm,
options,
keyData.bytes, keyLength,
iv,
data.bytes, data.length,
cryptData.mutableBytes, cryptData.length,
&numBytesEncrypted)
if UInt32(cryptStatus) == UInt32(kCCSuccess) {
cryptData.length = Int(numBytesEncrypted)
let unencryptedMessage = String(data: cryptData, encoding:NSUTF8StringEncoding)
return unencryptedMessage
}
else {
return nil
}
}
return nil
}
The functions were taken from RNCryptor. It was an easy addition in the hashing functions and in one single file "HMAC.swift", without using Bridging-header. I hope this will be useful for developers in swift requiring Hashing and AES Encryption/Decryption.
Example of using the AESDecrypt as under.
let iv = "AA-salt-BBCCDD--" // should be of 16 characters.
//here we are convert nsdata to String
let encryptedString = String(data: dataFromURL, encoding: NSUTF8StringEncoding)
//now we are decrypting
if let decryptedString = encryptedString?.aesDecrypt("12345678901234567890123456789012", iv: iv) // 32 char pass key
{
// Your decryptedString
}
The solution that fixed mine was that I had inadvertently applied different keys to Encryption and Decryption methods.
Once I'd discovered all the information of how my client was handling the encryption/decryption at their end it was straight forward using the AesManaged example suggested by dtb.
The finally implemented code started like this:
try
{
// Create a new instance of the AesManaged class. This generates a new key and initialization vector (IV).
AesManaged myAes = new AesManaged();
// Override the cipher mode, key and IV
myAes.Mode = CipherMode.ECB;
myAes.IV = new byte[16] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; // CRB mode uses an empty IV
myAes.Key = CipherKey; // Byte array representing the key
myAes.Padding = PaddingMode.None;
// Create a encryption object to perform the stream transform.
ICryptoTransform encryptor = myAes.CreateEncryptor();
// TODO: perform the encryption / decryption as required...
}
catch (Exception ex)
{
// TODO: Log the error
throw ex;
}
It's generally a bad idea to write your own cryptography unless you have experience breaking other peoples' cryptography implementations.
None of the examples here authenticate the ciphertext, which leaves them vulnerable to bit-rewriting attacks.
<?php
// PECL libsodium 0.2.1 and newer
/**
* Encrypt a message
*
* @param string $message - message to encrypt
* @param string $key - encryption key
* @return string
*/
function safeEncrypt($message, $key)
{
$nonce = \Sodium\randombytes_buf(
\Sodium\CRYPTO_SECRETBOX_NONCEBYTES
);
return base64_encode(
$nonce.
\Sodium\crypto_secretbox(
$message,
$nonce,
$key
)
);
}
/**
* Decrypt a message
*
* @param string $encrypted - message encrypted with safeEncrypt()
* @param string $key - encryption key
* @return string
*/
function safeDecrypt($encrypted, $key)
{
$decoded = base64_decode($encrypted);
$nonce = mb_substr($decoded, 0, \Sodium\CRYPTO_SECRETBOX_NONCEBYTES, '8bit');
$ciphertext = mb_substr($decoded, \Sodium\CRYPTO_SECRETBOX_NONCEBYTES, null, '8bit');
return \Sodium\crypto_secretbox_open(
$ciphertext,
$nonce,
$key
);
}
Then to test it out:
<?php
// This refers to the previous code block.
require "safeCrypto.php";
// Do this once then store it somehow:
$key = \Sodium\randombytes_buf(\Sodium\CRYPTO_SECRETBOX_KEYBYTES);
$message = 'We are all living in a yellow submarine';
$ciphertext = safeEncrypt($message, $key);
$plaintext = safeDecrypt($ciphertext, $key);
var_dump($ciphertext);
var_dump($plaintext);
This can be used in any situation where you are passing data to the client (e.g. encrypted cookies for sessions without server-side storage, encrypted URL parameters, etc.) with a reasonably high degree of certainty that the end user cannot decipher or reliably tamper with it.
Since libsodium is cross-platform, this also makes it easier to communicate with PHP from, e.g. Java applets or native mobile apps.
Note: If you specifically need to add encrypted cookies powered by libsodium to your app, my employer Paragon Initiative Enterprises is developing a library called Halite that does all of this for you.
Under Ubuntu I had the problem and solved it with
$ sudo apt-get install php5-mcrypt
$ sudo service apache2 reload
The server first tries to authenticate you by public key. That doesn't work (I guess you haven't set one up), so it then falls back to 'keyboard-interactive'. It should then ask you for a password, which presumably you're not getting right. Did you see a password prompt?
You should grab a copy of Erica Sadun's mdhelper command line utility (OS X binary & source). It supports listing and extracting the contents of iPhone/iPod Touch backups, including address book & SMS databases, and other application metadata and settings.
Some of the answers that are written here are pretty trivial (O(n^2) or sorting and traversing in O(NlogN)) and I'm assuming that is not what was expected in an interview for Microsoft. Obviously any answer above O(n) wasn't what they were looking for. The update states that there shouldn't be any helper data structures so any answer that has one (a hash table, tree, bit array or whatever) shouldn't be a valid solution.
If you can allocate additional memory then Jeff B's answer is probably easiest way to do it. I have a good answer for questions like these but the MAXINT needs to be bounded by the size of the array. (Example: An array of size 100 may contain any number between 1 and 100. Remove the dups as the original question)
The answer to this in O(n) time and O(1) memory is:
// FLAG ALL DUPS IN THE ORIGIN ARRAY
int maxNumInArray = findMaxNumInArray(arr);
int dup = findMinNumInArray(arr) - 1;
for (int i=0; i < arrLength; ++i) {
int seekIndex = arr[i] % (maxNumInArray+1);
if (arr[seekIndex] > maxNumInArray)
arr[i] = dup; // invalidate index
else
arr[seekIndex] = arr[seekIndex] + maxNumInArray;
}
// REMOVE EMPTY SPACES
int i = 0;
int j = arrLength(arr)-1;
while (i<j) {
while (arr[i] != dup)
++i;
while (arr[j] == dup)
--j;
swap(arr[i], arr[j]);
}
If you don't know the bounds my answer isn't useful but u can try and play with it. Oh, and this specific variation wont work with negative numbers but its not a problem to fix it.

In field parameters add -cleaninstall
Now just run, they always will do a deep clean before install.
The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:
ffmpeg -i input.mov -qscale 0 output.mp4
Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0
):
ffmpeg -i input.mov -q:v 0 output.mp4
Matplotlib uses a dictionary from its colors.py module.
To print the names use:
# python2:
import matplotlib
for name, hex in matplotlib.colors.cnames.iteritems():
print(name, hex)
# python3:
import matplotlib
for name, hex in matplotlib.colors.cnames.items():
print(name, hex)

You could plot them like this:
import matplotlib.pyplot as plt
import matplotlib.patches as patches
import matplotlib.colors as colors
import math
fig = plt.figure()
ax = fig.add_subplot(111)
ratio = 1.0 / 3.0
count = math.ceil(math.sqrt(len(colors.cnames)))
x_count = count * ratio
y_count = count / ratio
x = 0
y = 0
w = 1 / x_count
h = 1 / y_count
for c in colors.cnames:
pos = (x / x_count, y / y_count)
ax.add_patch(patches.Rectangle(pos, w, h, color=c))
ax.annotate(c, xy=pos)
if y >= y_count-1:
x += 1
y = 0
else:
y += 1
plt.show()
var classList = $(element).attr('class').split(/\s+/);
$(classList).each(function(index){

});
Unique Key (UK): It's a column or a group of columns that can identify a uniqueness in a row.
Primary Key (PK): It's also a column or group of columns that can identify a uniqueness in a row.
So the Primary key is just another name for unique key, but the default implementation in SQL Server is different for Primary and Unique Key.
By Default:
It really depends what is your aim when deciding whether to create a UK or PK. It follows an analogy like "If there is a team of three people, so all of them are peers, but there will be one of them who will be a pair of peers: PK and UK has similar relation.". I would suggest reading this article: The example given by the author may not seem suitable, but try to get an overall idea.
http://tsqltips.blogspot.com/2012/06/difference-between-unique-key-and.html
I would generally prefer something a bit simpler, like activate
/deactivate
sub-resource (linked by a Link
header with rel=service
).
POST /groups/api/v1/groups/{group id}/activate
or
POST /groups/api/v1/groups/{group id}/deactivate
For the consumer, this interface is dead-simple, and it follows REST principles without bogging you down in conceptualizing "activations" as individual resources.
You can specify also imagePullPolicy: Never
in the container's spec:
containers:
- name: nginx
imagePullPolicy: Never
image: custom-nginx
ports:
- containerPort: 80
Try something like this inside ThisOutlookSession
:
Private Sub Application_NewMail()
Call Your_main_macro
End Sub
My outlook vba just fired when I received an email and had that application event open.
Edit: I just tested a hello world msg box and it ran after being called in the application_newmail
event when an email was received.
You can use method getDate():
$('#calendar').datepicker({
dateFormat: 'yy-m-d',
inline: true,
onSelect: function(dateText, inst) {
var date = $(this).datepicker('getDate'),
day = date.getDate(),
month = date.getMonth() + 1,
year = date.getFullYear();
alert(day + '-' + month + '-' + year);
}
});
As commented by Chris, enums require much more memory on Android that adds up as they keep being used everywhere. You should try IntDef or StringDef instead, which use annotations so that the compiler validates passed values.
public abstract class ActionBar {
...
@IntDef({NAVIGATION_MODE_STANDARD, NAVIGATION_MODE_LIST, NAVIGATION_MODE_TABS})
@Retention(RetentionPolicy.SOURCE)
public @interface NavigationMode {}
public static final int NAVIGATION_MODE_STANDARD = 0;
public static final int NAVIGATION_MODE_LIST = 1;
public static final int NAVIGATION_MODE_TABS = 2;
@NavigationMode
public abstract int getNavigationMode();
public abstract void setNavigationMode(@NavigationMode int mode);
It can also be used as flags, allowing for binary composition (OR / AND operations).
EDIT: It seems that transforming enums into ints is one of the default optimizations in Proguard.
var newItem = document.createElement("LI"); // Create a <li> node
var textnode = document.createTextNode("Water"); // Create a text node
newItem.appendChild(textnode); // Append the text to <li>
var list = document.getElementById("myList"); // Get the <ul> element to insert a new node
list.insertBefore(newItem, list.childNodes[0]); // Insert <li> before the first child of <ul>

EDIT: As pointed out by users, don't use MQ, use commit --amend
. This answer is mostly of historic interest now.
As others have mentioned the MQ extension is much more suited for this task, and you don't run the risk of destroying your work. To do this:
Enable the MQ extension, by adding something like this to your hgrc:

Update to the changeset you want to edit, typically tip:
hg up $rev
Import the current changeset into the queue:
hg qimport -r .
Refresh the patch, and edit the commit message:
hg qrefresh -e
Finish all applied patches (one, in this case) and store them as regular changesets:
hg qfinish -a
I'm not familiar with TortoiseHg, but the commands should be similar to those above. I also believe it's worth mentioning that editing history is risky; you should only do it if you're absolutely certain that the changeset hasn't been pushed to or pulled from anywhere else.
You must update all blocks in SDK Manager (Support Library, etc.), all non updated libs and packages. After this you must sync gradle files with project and rejoice!

Simply as bellow;
$this->db->get('table_name')->num_rows();
This will get number of rows/records. however you can use search parameters as well;
$this->db->select('col1','col2')->where('col'=>'crieterion')->get('table_name')->num_rows();
However, it should be noted that you will see bad bad errors if applying as below;
$this->db->get('table_name')->result()->num_rows();
Yeah first method will work on any element called from elsewhere since it will always take the target element irrespective of id.

Java IO using stream oriented APIs is performed using a buffer as temporary storage of data within user space. Data read from disk by DMA is first copied to buffers in kernel space, which is then transfer to buffer in user space. Hence there is overhead. Avoiding it can achieve considerable gain in performance.
We could skip this temporary buffer in user space, if there was a way directly to access the buffer in kernel space. Java NIO provides a way to do so.
ByteBuffer
is among several buffers provided by Java NIO. Its just a container or holding tank to read data from or write data to. Above behavior is achieved by allocating a direct buffer using allocateDirect()
API on Buffer.
For this, I use FLAG_ACTIVITY_CLEAR_TOP
flag for starting Intent
(without FLAG_ACTIVITY_NEW_TASK
)
and launchMode = "singleTask"
in manifest for launched activity.
Seems like it works as I need - activity does not restart and all other activities are closed.
It is an SELinux issue.
You can temporarily issue
su -c "setenforce 0"
on the host to access or else add an SELinux rule by running
chcon -Rt svirt_sandbox_file_t /path/to/volume

In the pgAdmin4, Right click on table select backup like this
After that into the backup dialog there is Dump options tab into that there is section queries you can select Use Insert Commands which include all insert queries as well in the backup.
Like this:
>>> text = 'a,b,c'
>>> text = text.split(',')
>>> text
[ 'a', 'b', 'c' ]
Alternatively, you can use eval()
if you trust the string to be safe:
>>> text = 'a,b,c'
>>> text = eval('[' + text + ']')
I used the following instructions to upgrade from Node.js version 0.10.6 to 0.10.21 on a Mac.
Clear NPM's cache:
sudo npm cache clean -f
Install a little helper called 'n'
sudo npm install -g n
Install latest stable Node.js version
sudo n stable
Alternatively pick a specific version and install like this:
sudo n 0.8.20
For production environments you might want to pay attention to version numbering and be picky about odd/even numbers.

Update (June 2017):
This four years old post still receives up-votes so I'm guessing it still works for many people. However, Mr. Walsh himself recommended to update Node.js just using nvm instead.
So here's what you might want to do today:
Find out which version of Node.js you are using:
node --version
Find out which versions of Node.js you may have installed and which one of those you're currently using:
nvm ls
List all versions of Node.js available for installation:
nvm ls-remote
Apparently for Windows the command would be rather like this:
nvm ls available
Assuming you would pick Node.js v8.1.0 for installation you'd type the following to install that version:
nvm install 8.1.0
You are then free to choose between installed versions of Node.js. So if you would need to use an older version like v4.2.0 you would set it as the active version like this:
nvm use 4.2

I know this is an old question, but nobody mentioned that when your data looks like an array, numpy's loadtxt comes in handy:
>>> import numpy as np
>>> np.loadtxt("myfile.txt")[:, 1]
array([10., 20., 30., 40., 23., 13.])
Be sure to fully qualify your sheets with which workbook they are referencing!
mainWB.Sheets.Add(After:=mainWB.Sheets(mainWB.Sheets.Count)).Name = new_sheet_name
Verilog thinks in bits, so reg [7:0] a[0:3]
will give you a 4x8 bit array (=4x1 byte array). You get the first byte out of this with a[0]
. The third bit of the 2nd byte is a[1][2]
.
For a 2D array of bytes, first check your simulator/compiler. Older versions (pre '01, I believe) won't support this. Then reg [7:0] a [0:3] [0:3]
will give you a 2D array of bytes. A single bit can be accessed with a[2][0][7]
for example.
reg [7:0] a [0:3];
reg [7:0] b [0:3] [0:3];
reg [7:0] c;
reg d;
initial begin
for (int i=0; i<=3; i++) begin
a[i] = i[7:0];
end
c = a[0];
d = a[1][2];
// using 2D
for (int i=0; i<=3; i++)
for (int j=0; j<=3; j++)
b[i][j] = i*j; // watch this if you're building hardware
end

I'm using buck and it seems like by removing the /.idea/libraries

I'm reluctant to add yet another answer, but I've had to beg, borrow and steal from the others to get what I want, which is a complete list of all the FK relationships on tables in a given schema, INCLUDING FKs to tables in other schemas. The two crucial recordsets are information_schema.KEY_COLUMN_USAGE and information_schema.referential_constraints. If an attribute you want is missing, just uncomment the KCU., RC. to see what's available
SELECT DISTINCT KCU.TABLE_NAME, KCU.COLUMN_NAME, REFERENCED_TABLE_SCHEMA, KCU.REFERENCED_TABLE_NAME, KCU.REFERENCED_COLUMN_NAME, UPDATE_RULE, DELETE_RULE #, KCU.*, RC.*
FROM information_schema.KEY_COLUMN_USAGE KCU
INNER JOIN information_schema.referential_constraints RC ON KCU.CONSTRAINT_NAME = RC.CONSTRAINT_NAME
WHERE TABLE_SCHEMA = (your schema name)
AND KCU.REFERENCED_TABLE_NAME IS NOT NULL
ORDER BY KCU.TABLE_NAME, KCU.COLUMN_NAME;
A. Grab file data from the file field
The first thing to do is bind a function to the change event on your file field and a function for grabbing the file data:
// Variable to store your files
var files;
// Add events
$('input[type=file]').on('change', prepareUpload);
// Grab the files and set them to our variable
function prepareUpload(event)
{
files = event.target.files;
}
This saves the file data to a file variable for later use.
B. Handle the file upload on submit
When the form is submitted you need to handle the file upload in its own AJAX request. Add the following binding and function:
$('form').on('submit', uploadFiles);
// Catch the form submit and upload the files
function uploadFiles(event)
{
event.stopPropagation(); // Stop stuff happening
event.preventDefault(); // Totally stop stuff happening
// START A LOADING SPINNER HERE
// Create a formdata object and add the files
var data = new FormData();
$.each(files, function(key, value)
{
data.append(key, value);
});
$.ajax({
url: 'submit.php?files',
type: 'POST',
data: data,
cache: false,
dataType: 'json',
processData: false, // Don't process the files
contentType: false, // Set content type to false as jQuery will tell the server its a query string request
success: function(data, textStatus, jqXHR)
{
if(typeof data.error === 'undefined')
{
// Success so call function to process the form
submitForm(event, data);
}
else
{
// Handle errors here
console.log('ERRORS: ' + data.error);
}
},
error: function(jqXHR, textStatus, errorThrown)
{
// Handle errors here
console.log('ERRORS: ' + textStatus);
// STOP LOADING SPINNER
}
});
}
What this function does is create a new formData object and appends each file to it. It then passes that data as a request to the server. 2 attributes need to be set to false:
C. Upload the files
Quick and dirty php script to upload the files and pass back some info:
<?php // You need to add server side validation and better error handling here
$data = array();
if(isset($_GET['files']))
{
$error = false;
$files = array();
$uploaddir = './uploads/';
foreach($_FILES as $file)
{
if(move_uploaded_file($file['tmp_name'], $uploaddir .basename($file['name'])))
{
$files[] = $uploaddir .$file['name'];
}
else
{
$error = true;
}
}
$data = ($error) ? array('error' => 'There was an error uploading your files') : array('files' => $files);
}
else
{
$data = array('success' => 'Form was submitted', 'formData' => $_POST);
}
echo json_encode($data);
?>
IMP: Don't use this, write your own.
D. Handle the form submit
The success method of the upload function passes the data sent back from the server to the submit function. You can then pass that to the server as part of your post:
function submitForm(event, data)
{
// Create a jQuery object from the form
$form = $(event.target);
// Serialize the form data
var formData = $form.serialize();
// You should sterilise the file names
$.each(data.files, function(key, value)
{
formData = formData + '&filenames[]=' + value;
});
$.ajax({
url: 'submit.php',
type: 'POST',
data: formData,
cache: false,
dataType: 'json',
success: function(data, textStatus, jqXHR)
{
if(typeof data.error === 'undefined')
{
// Success so call function to process the form
console.log('SUCCESS: ' + data.success);
}
else
{
// Handle errors here
console.log('ERRORS: ' + data.error);
}
},
error: function(jqXHR, textStatus, errorThrown)
{
// Handle errors here
console.log('ERRORS: ' + textStatus);
},
complete: function()
{
// STOP LOADING SPINNER
}
});
}
Final note
This script is an example only, you'll need to handle both server and client side validation and some way to notify users that the file upload is happening. I made a project for it on Github if you want to see it working.
PHP has to be parsed on the server. JavaScript is working in the client's browser.
Having PHP code in a .js file will not work, except you can tell the server to parse the file you want to have as .js before it sends it to the client. And telling the server is the easiest thing in the world: just add .php at the end of the filename.
So, you could name it javascript.php
. Or, so you know what this file is PRIMARILY, you could name it javascript.js.php - the server will recognize it as .php and parse it.
Using subset
:
missing<-subset(a1, !(a %in% a2$a))
Change the .env file as follow

MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls
And the go to the gmail security section ->Allow Less secure app access
Then run
php artisan config:clear

Having something in an anonymous namespace means it's local to this translation unit (.cpp file and all its includes) this means that if another symbol with the same name is defined elsewhere there will not be a violation of the One Definition Rule (ODR).
This is the same as the C way of having a static global variable or static function but it can be used for class definitions as well (and should be used rather than static
in C++).
All anonymous namespaces in the same file are treated as the same namespace and all anonymous namespaces in different files are distinct. An anonymous namespace is the equivalent of:
namespace __unique_compiler_generated_identifer0x42 {
...
}
using namespace __unique_compiler_generated_identifer0x42;
If its only for validating you could do: 887979789 > 99999999
basically:

using System.Net.Http; // in LINQPad, also add a reference to System.Net.Http.dll

string source;
using (StreamReader reader = new StreamReader(req.GetResponse().GetResponseStream()))
{
source = reader.ReadToEnd();

Console.WriteLine(source);

I personally prefer to use as few not built-in bash
commands as I can (to reduce the number of expensive fork and exec syscalls). To sort by date the ls
needed to be called. But using of head
is not really necessary. I use the following one-liner (works only on systems supporting name pipes):
read newest < <(ls -t *.log)
or to get the name of the oldest file
read oldest < <(ls -rt *.log)
(Mind the space between the two '<' marks!)
If the hidden files are also needed -A arg could be added.
I hope this could help.
I would go for aspect-ratio, it offers way more possibilities.
/* Exact aspect ratio */
@media (aspect-ratio: 2/1) {
...
}
/* Minimum aspect ratio */
@media (min-aspect-ratio: 16/9) {
...
}
/* Maximum aspect ratio */
@media (max-aspect-ratio: 8/5) {
...
}
Both, orientation and aspect-ratio depend on the actual size of the viewport and have nothing todo with the device orientation itself.

In relative layout you need specify textview height:
android:layout_height="100dp"
Or specify lines attribute:
android:lines="3"
It was due to IE Document-mode version too low. Press 'F12' and using higher version( My case, above version 9 is OK)
I didn't compile it... but should work (or be close to working).
public static <T> String toString(final List<T> list,
final String delim)
{
final StringBuilder builder;
builder = new StringBuilder();
for(final T item : list)

builder.append(item);
builder.append(delim);
}
// kill the last delim
builder.setLength(builder.length() - delim.length());
return (builder.toString());
}
Yes, there is a better way: You can use the $parse service in your directive to evaluate an expression in the context of the parent scope while binding certain identifiers in the expression to values visible only inside your directive:
$parse(attributes.callback)(scope.$parent, { arg2: yourSecondArgument });
Add this line to the link function of the directive where you can access the directive's attributes.
Your callback attribute may then be set like callback = "callback(item.id, arg2)"
because arg2 is bound to yourSecondArgument by the $parse service inside the directive. Directives like ng-click
let you access the click event via the $event
identifier inside the expression passed to the directive by using exactly this mechanism.
Note that you do not have to make callback
a member of your isolated scope with this solution.
NOTE - it looks like the question has changed some. The answer to the question of how you call an instance method from a static method is that you can't without passing an instance in as an argument or instantiating that instance inside the static method.
What follows is mostly to answer "how do you call a static method from another static method":
Bear in mind that there is a difference between static methods and class methods in Python. A static method takes no implicit first argument, while a class method takes the class as the implicit first argument (usually cls
by convention). With that in mind, here's how you would do that:
If it's a static method:
test.dosomethingelse()
If it's a class method:
cls.dosomethingelse()
This solution worked for me.
First finish the activity and then start it again.
Sample code:
public void restartActivity(){
Intent mIntent = getIntent();
finish();
startActivity(mIntent);
}
For Each is much faster than for I=1 to X, for some reason. Just try to go through the same dictionary,
once with for each Dkey in dDict,
and once with for Dkey = lbound(dDict.keys) to ubound(dDict.keys)
=>You will notice a huge difference, even though you are going through the same construct.
Try this way. It got worked for me

If your Exchange server is configured to support POP or IMAP, that's an easy way out.
Another option is WebDAV access. there is a library available for that. This might be your best option.
I think there are options using COM objects to access Exchange, but I'm not sure how easy it is.
It all depends on what exactly your administrator is willing to give you access to I guess.
For n up to 10**16 (maybe even a bit more), here is a fast pure Python 3.6 solution,
from itertools import compress
def primes(n):

sieve = bytearray([True]) * (n//2)
for i in range(3,int(n**0.5)+1,2):
if sieve[i//2]:
sieve[i*i//2::i] = bytearray((n-i*i-1)//(2*i)+1)
return [2,*compress(range(3,n,2), sieve[1:])]
def factorization(n):
""" Returns a list of the prime factorization of n """
pf = []
for p in primeslist:
if p*p > n : break
count = 0
while not n % p:
n //= p
count += 1
if count > 0: pf.append((p, count))
if n > 1: pf.append((n, 1))
return pf
def divisors(n):
""" Returns an unsorted list of the divisors of n """
divs = [1]
for p, e in factorization(n):
divs += [x*p**k for k in range(1,e+1) for x in divs]
return divs
n = 600851475143

Which Log file? Well -- you can check the physical path by right-clicking on the System Log (e.g. Server Manager | Diagnostics | Event Viewer | Windows Logs). The default physical path is %SystemRoot%\System32\Winevt\Logs\System.evtx
.
You can create a Custom Filter and filter by "Source: WAS" to quickly see only entries generated by IIS.
You may need first to enable logging of such even for a specific App Pool -- by default App Pool has only 3 recycle events out of 8 enabled. To change it using GUI: II S Manager | Application Pools | Select App Pool -> Advanced Settings | Generate Recycle Event Log Entry.
From the api on GridLayout:
The container is divided into equal-sized rectangles, and one component is placed in each rectangle.
Try using FlowLayout or GridBagLayout for your set size to be meaningful. Also, @Serplat is correct. You need to use setPreferredSize( Dimension ) instead of setSize( int, int ).
JPanel displayPanel = new JPanel();
// JPanel displayPanel = new JPanel( new GridLayout( 4, 2 ) );
// JPanel displayPanel = new JPanel( new BorderLayout() );
// JPanel displayPanel = new JPanel( new GridBagLayout() );
JTextField titleText = new JTextField( "title" );
titleText.setPreferredSize( new Dimension( 200, 24 ) );
// For FlowLayout and GridLayout, uncomment:
displayPanel.add( titleText );
// For BorderLayout, uncomment:
// displayPanel.add( titleText, BorderLayout.NORTH );
// For GridBagLayout, uncomment:
// displayPanel.add( titleText, new GridBagConstraints( 0, 0, 1, 1, 1.0,
// 1.0, GridBagConstraints.CENTER, GridBagConstraints.NONE,
// new Insets( 0, 0, 0, 0 ), 0, 0 ) );
You can add float:none; margin:auto;
styling to centerize column content.
You could create Util class:
public final class CollectionHelpers {
public static <T> boolean addNullSafe(List<T> list, T element) {
if (list == null || element == null) {
return false;
}
return list.add(element);
}
}
And then use it:
Element element = getElementFromSomeWhere(someParameter);
List<Element> arrayList = new ArrayList<>();
CollectionHelpers.addNullSafe(list, element);
while not any( x in ('AND','OR','NOT') for x in list)
EDIT:
thank you for the upvotes , but etarion's solution is better since it tests if the words AND, OR, NOT are in the list, that is to say 3 tests.
Mine does as many tests as there are words in list.
EDIT2:
Also there is
while not ('AND' in list,'OR' in list,'NOT' in list)==(False,False,False)
For single-page sites where the menu items simply jump down to other sections of the page, this simple solution works for me:
$('.nav li').on('click', function(){
$('.nav li').removeClass('active');
$(this).addClass('active');
});
Completely untested, but this should work:
View positiveButton = findViewById(R.id.positiveButton);
RelativeLayout.LayoutParams layoutParams =
(RelativeLayout.LayoutParams)positiveButton.getLayoutParams();
layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
positiveButton.setLayoutParams(layoutParams);
add android:configChanges="orientation|screenSize"
inside your activity in your manifest
While the accepted answer will work fine if the bytes you have from your subprocess are encoded using sys.stdout.encoding
(or a compatible encoding, like reading from a tool that outputs ASCII and your stdout uses UTF-8), the correct way to write arbitrary bytes to stdout is:
sys.stdout.buffer.write(some_bytes_object)
This will just output the bytes as-is, without trying to treat them as text-in-some-encoding.
If you just want to see the changes in the latest commit, simply git show
will give you that.
Use substitute
instead.
labNames <- c('xLab','yLab')
plot(c(1:10),
xlab=substitute(paste(nn, x^2), list(nn=labNames[1])),
ylab=substitute(paste(nn, y^2), list(nn=labNames[2])))
Simple solution which properly handles ByteOrder:
ByteBuffer.allocate(4).order(ByteOrder.nativeOrder()).putInt(yourInt).array();
I would like to add another way of changing a character in a string.
>>> text = '~~~~~~~~~~~'
>>> text = text[:1] + (text[1:].replace(text[0], '+', 1))
'~+~~~~~~~~~'
How faster it is when compared to turning the string into list and replacing the ith value then joining again?.
List approach
>>> timeit.timeit("text = '~~~~~~~~~~~'; s = list(text); s[1] = '+'; ''.join(s)", number=1000000)
0.8268570480013295
My solution
>>> timeit.timeit("text = '~~~~~~~~~~~'; text=text[:1] + (text[1:].replace(text[0], '+', 1))", number=1000000)
0.588400217000526
You can remove the close button with the code below. There are other options as well which you might fight useful.
$('#dialog-modal').dialog({
//To hide the Close 'X' button
"closeX": false,
//To disable closing the pop up on escape
"closeOnEscape": false,
//To allow background scrolling
"allowScrolling": true
})
//To remove the whole title bar
.siblings('.ui-dialog-titlebar').remove();
jQuery recently started using source maps.
For example, let's look at the minified jQuery 2.0.3 file's first few lines.
/*! jQuery v2.0.3 | (c) 2005, 2013 jQuery Foundation, Inc. | jquery.org/license
//@ sourceMappingURL=jquery.min.map
*/
Excerpt from Introduction to JavaScript Source Maps:
Have you ever found yourself wishing you could keep your client-side code readable and more importantly debuggable even after you've combined and minified it, without impacting performance? Well now you can through the magic of source maps.
Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location. Developer tools (currently WebKit nightly builds, Google Chrome, or Firefox 23+) can parse the source map automatically and make it appear as though you're running unminified and uncombined files.
emphasis mine
It's incredibly useful, and will only download if the user opens dev tools.
Remove the source mapping line, or do nothing. It isn't really a problem.
Side note: your server should return 404, not 500. It could point to a security problem if this happens in production.
<?php

if ($_POST['user'] != $username) {
echo "Sorry, that username does not match.";
exit;

echo "Sorry, you could not be logged in at this time.";
}
}
?>
And the login form on the page...
(On the same page, right below the above^ posted code)
<form action="<?php echo $_SERVER['PHP_SELF']; ?>?p=login" method="post">
<label><input type="text" name="user" id="user" /> Name</label><br />
<label><input type="password" name="keypass" id="keypass" /> Password</label><br />
<input type="submit" id="submit" value="Login" />
</form>
Had the same problem and thanks to you mentioning that the real problem was related to CSS I found the issue:
Having position:relative
instead of position:absolute
in your .ui-dialog
CSS rule makes the dialog and width:'auto'
behave strangely.
.ui-dialog { position: absolute;}
If you have the extension method:
public static bool? ToBoolean(this string s)
{
bool result;
if (bool.TryParse(s, out result))
return result;
else
return null;
}
and this code:
string nullStr = null;
var res = nullStr.ToBoolean();
This will not throw an exception because it is an extension method (and really HelperClass.ToBoolean(null)
) and not an instance method. This can be confusing.
I believe it's because it can execute any JavaScript function from a string. Using it makes it easier for people to inject rogue code into the application.
You can update/install the node by reinstalling the installed package to the current version which may save us from lotta of errors, while doing the update.
This is done by nvm with the below command. Here, I have updated my node version to 8 and reinstalled all the available packages to v8 too!
nvm i v8 --reinstall-packages-from=default
It works on AWS Linux instance as well.
Try this

In Visual Studio 2017 if you want to test public members, simply put your real project and test project in the same solution, and add a reference to your real project in the test project.
See C++ Unit Testing in Visual Studio from the MSDN blog for more details. You can also check Write unit tests for C/C++ in Visual Studio as well as Use the Microsoft Unit Testing Framework for C++ in Visual Studio, the latter being if you need to test non public members and need to put the tests in the same project as your real code.
Note that things you want to test will need to be exported using __declspec(dllexport)
. See Exporting from a DLL Using __declspec(dllexport) for more details.
//checking even and odd
$num =14;

}
Can you try a custom CSS aside the bootstrap CSS to see if any changes. Try
.move-rigth{
display: block;
float: right;
}
If it works then you can try manipulating what you have or adding other formatting to this and achieving what you desire. Because you are using bootstrap doesn't mean if it doesn't offer you what you want then you just manage it. You are working with your codes and so you command it to do as you say. Cheers!
To whom its just not working to (like me) no matter what you tried:
<element onscroll="myFunction()"></element>
works like a charm
exactly as they explain in W3 schools https://www.w3schools.com/tags/ev_onscroll.asp
Inside onCreateView method
1) first you have to inflate the layout/view you want to add eg. LinearLayout
LinearLayout ll = inflater.inflate(R.layout.testclassfragment, container, false);
2) Then you can find your imageView id from layout
ImageView imageView = (ImageView)ll.findViewById(R.id.my_image);
3)return the inflated layout
return ll;
com.nhaarman.mockitokotlin2.mock {}
This error occurs when, for example, we create a mock inside another mock
mock {
on { x() } doReturn mock {
on { y() } doReturn z()
}
}
The solution to this is to create the child mock in a variable and use the variable in the scope of the parent mock to prevent the mock creation from being explicitly nested.
val liveDataMock = mock {
on { y() } doReturn z()
}
mock {
on { x() } doReturn liveDataMock
}

If you want to increase or add time limit to all sites then you can add below lines to the
nginx.conf
file.
Add below lines to the http
section of /usr/local/etc/nginx/nginx.conf
or /etc/nginx/nginx.conf
file.
fastcgi_read_timeout 600;
proxy_read_timeout 600;
If the above lines doesn't exist in conf
file then add them, otherwise increase fastcgi_read_timeout
and proxy_read_timeout
to make sure that nginx and php-fpm did not timeout.
To increase time limit for only one site then you can edit in vim
/etc/nginx/sites-available/example.com
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_read_timeout 300;
}
and after adding these lines in nginx.conf
, then don't forget to restart nginx.
service php7-fpm reload
service nginx reload
or, if you're using valet then simply type valet restart
.
I have just found this pretty solution:
import sys; sys.path.insert(0, '..') # add parent folder path where lib folder is
import lib.store_load # store_load is a file on my library folder
You just want some functions of that file
from lib.store_load import your_function_name
If python version >= 3.3 you do not need init.py file in the folder
Use DateTime.TryParseExact()
if you want to match against a specific date format
string format = "ddd dd MMM h:mm tt yyyy";
DateTime dateTime;
if (DateTime.TryParseExact(dateString, format, CultureInfo.InvariantCulture,
DateTimeStyles.None, out dateTime))
{
Console.WriteLine(dateTime);
}
else
{
Console.WriteLine("Not a date");
}
You can clearly remember difference by this:
Mutex lock : is for protecting critical region, Mutex can't be used across processes, only used in single process
Semaphore: is for signalling availability of a resource. Semaphore can be used both across processes and across processes.
The proper way to do this is like this:
LIBS += -L/path/to -lpsapi
This way it will work on all platforms supported by Qt. The idea is that you have to separate the directory from the library name (without the extension and without any 'lib' prefix). Of course, if you are including a Windows specific lib, this really doesn't matter.
In case you want to store your lib files in the project directory, you can reference them with the $$_PRO_FILE_PWD_
variable, e.g.:
LIBS += -L"$$_PRO_FILE_PWD_/3rdparty/libs/" -lpsapi
Try something similar to this:
#include <stdio.h>
#include <string.h>
int main(int argc, const char * argv[])
{
// Insert code here...
char firstname[100], secondname[100];
printf("Enter First Name: ");
fgets(firstname, 100, stdin);
printf("Enter Second Name: ");
fgets(secondname,100,stdin);
firstname[strlen(firstname)-1]= '\0';
printf("fullname is %s %s", firstname, secondname);
return 0;
}
You can also use the following command:
pylint --disable=C0321 test.py
My Pylint version is 0.25.1.
Do simply like below....
HashMap<String,Object> yourHash = new HashMap<String,Object>();
yourHash.put(yourKey+"message","message");
yourHash.put(yourKey+"timestamp",timestamp);
yourHash.put(yourKey+"count ",count);
yourHash.put(yourKey+"version ",version);
typecast the value while getting back. For ex:
int count = Integer.parseInt(yourHash.get(yourKey+"count"));
//or
int count = Integer.valueOf(yourHash.get(yourKey+"count"));
//or
int count = (Integer)yourHash.get(yourKey+"count"); //or (int)
The accepted answer is good for smaller numbers, most importantly while you are taking data from excel sheets. as the bigger numbers will automatically converted to scientific numbers i.e. e+10.
So I think this will give you more general answer. I didn't check if it have any downfall or not.
CStr(CDbl(#yourNumber#))
this will work for e+ converted numbers! as the just CStr(7.7685099559e+11)
will be shown as "7.7685099559e+11" not as expected: "776850995590" So I rather to say my answer will be more generic result.

This is exactly how it worked for me. For some reason the above code failed.
This one runs a check every 3 minutes for any files in there and auto moves it to the destination folder. If you need to be prompted for conflicts then change the /y to /-y
:backup
move /y "D:\Dropbox\Dropbox\Camera Uploads\*.*" "D:\Archive\Camera Uploads\"
timeout 360
goto backup
This can also be done in the GUI:
Use the <button>
tag instead. <button>
labels are vertically centered by default.
Building off of Fabio's answer, I created two functions that will probably be useful for anyone stumbling upon this question. With these two functions, you can call insertParam()
with a key and value as an argument. It will either add the URL parameter or, if a query param already exists with the same key, it will change that parameter to the new value:
//function to remove query params from a URL
function removeURLParameter(url, parameter) {
//better to use l.search if you have a location/link object
var urlparts= url.split('?');
if (urlparts.length>=2) {
var prefix= encodeURIComponent(parameter)+'=';
var pars= urlparts[1].split(/[&;]/g);
//reverse iteration as may be destructive
for (var i= pars.length; i-- > 0;) {
//idiom for string.startsWith
if (pars[i].lastIndexOf(prefix, 0) !== -1) {
pars.splice(i, 1);
}
}
url= urlparts[0] + (pars.length > 0 ? '?' + pars.join('&') : "");
return url;
} else {
return url;
}
}
//function to add/update query params
function insertParam(key, value) {
if (history.pushState) {
// var newurl = window.location.protocol + "//" + window.location.host + search.pathname + '?myNewUrlQuery=1';
var currentUrlWithOutHash = window.location.origin + window.location.pathname + window.location.search;
var hash = window.location.hash
//remove any param for the same key
var currentUrlWithOutHash = removeURLParameter(currentUrlWithOutHash, key);
//figure out if we need to add the param with a ? or a &
var queryStart;
if(currentUrlWithOutHash.indexOf('?') !== -1){
queryStart = '&';
} else {
queryStart = '?';
}
var newurl = currentUrlWithOutHash + queryStart + key + '=' + value + hash
window.history.pushState({path:newurl},'',newurl);
}
}
As the rule of thumb, NumPy arrays often outperform other solutions while working with POD, Plain Old Data. A string is an example of POD and a character too. To find all the indices of only one char in a string, NumPy ndarrays may be the fastest way:
def find1(str, ch):
# 0.100 seconds for 1MB str
npbuf = np.frombuffer(str, dtype=np.uint8) # Reinterpret str as a char buffer
return np.where(npbuf == ord(ch)) # Find indices with numpy
def find2(str, ch):
# 0.920 seconds for 1MB str
return [i for i, c in enumerate(str) if c == ch] # Find indices with python
I think this is worthy of a separate answer: although internally unicode data is stored as UTF-16 in Sql Server this is the Little Endian flavour, so if you're calling the database from an external system, you probably need to specify UTF-16LE.
I was getting this error:
The type com.ibm.portal.state.exceptions.StateException cannot be resolved. It is indirectly referenced from required .class files
Doing the following fixed it for me:
Properties -> Java build path -> Libraries -> Server Library[wps.base.v61]unbound -> Websphere Portal v6.1 on WAS 7 -> Finish -> OK
Programmatically in Java - At least API v14+

Once you have a library downloaded you can execute this from the MS-DOS command box:
python setup.py install
The setup.py
is located inside every library main folder.
I wrote an updated version of Kees C. Bakker's answer:
const hasVerticalScroll = (node) => {
if (!node) {
if (window.innerHeight) {
return document.body.offsetHeight > window.innerHeight
}
return (document.documentElement.scrollHeight > document.documentElement.offsetHeight)
|| (document.body.scrollHeight > document.body.offsetHeight)
}
return node.scrollHeight > node.offsetHeight
}
if (hasVerticalScroll(document.querySelector('body'))) {
this.props.handleDisableDownScrollerButton()
}
The function returns true or false depending whether the page has a vertical scrollbar or not.
For example:
const hasVScroll = hasVerticalScroll(document.querySelector('body'))
if (hasVScroll) {
console.log('HAS SCROLL', hasVScroll)
}
I wanted to keep a few recent stashes, but delete everything else.
Because all stashes get renumbered when you drop one, this is actually easy to do with while. To delete all stashes older than stash@{19}:
while git stash drop 'stash@{20}'; do true; done
For what it worth, I had the same problem over my own VPS and it was caused by my low hard disk space on VPS. Confirmed by df -h
command and after i cleaned up my VPS' hard disk; the problem was gone.
Cheers.
With version 2.3.4, you need the to add the owl.autoplay.js plugin. Then do the following
var owl = $('.owl-carousel');
owl.owlCarousel({
items:1, //how many items you want to display
loop:true,
margin:10,
autoplay:true,
autoplayTimeout:10000,
autoplayHoverPause:true
});
Try using jQuery.parseJSON when you get the data back.
type: "POST",
dataType: "json",
url: url,
data: { get_member: id },
success: function(data) {
response = jQuery.parseJSON(data);
$("input[ name = type ]:eq(" + response.type + " )")
.attr("checked", "checked");
$("input[ name = name ]").val( response.name);
$("input[ name = fname ]").val( response.fname);
$("input[ name = lname ]").val( response.lname);
$("input[ name = email ]").val( response.email);
$("input[ name = phone ]").val( response.phone);
$("input[ name = website ]").val( response.website);
$("#admin_member_img")
.attr("src", "images/member_images/" + response.image);
},
error: function(error) {
alert(error);
}
For executeUpdate statements against a DB2 for z/OS server, the value that is returned depends on the type of SQL statement that is being executed:
For an SQL statement that can have an update count, such as an INSERT, UPDATE, or DELETE statement, the returned value is the number of affected rows. It can be:
A positive number, if a positive number of rows are affected by the operation, and the operation is not a mass delete on a segmented table space.
0, if no rows are affected by the operation.
-1, if the operation is a mass delete on a segmented table space.
For a DB2 CALL statement, a value of -1 is returned, because the DB2 database server cannot determine the number of affected rows. Calls to getUpdateCount or getMoreResults for a CALL statement also return -1. For any other SQL statement, a value of -1 is returned.
According to the Apple docs:
This method is called when the view controller's view's size is changed by its parent (i.e. for the root view controller when its window rotates or is resized).
override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
super.viewWillTransition(to: size, with: coordinator)
if UIDevice.current.orientation.isLandscape {
print("Landscape")
}
if UIDevice.current.orientation.isFlat {
print("Flat")
} else {
print("Portrait")
}
}
CreateOrReplaceTempView will create a temporary view of the table on memory it is not presistant at this moment but you can run sql query on top of that . if you want to save it you can either persist or use saveAsTable to save.
first we read data in csv format and then convert to data frame and create a temp view
Reading data in csv format
val data = spark.read.format("csv").option("header","true").option("inferSchema","true").load("FileStore/tables/pzufk5ib1500654887654/campaign.csv")
printing the schema
data.printSchema
data.createOrReplaceTempView("Data")
Now we can run sql queries on top the table view we just created
%sql select Week as Date,Campaign Type,Engagements,Country from Data order by Date asc
One option is to put the subquery in a LEFT JOIN
:
select sum ( t.graduates ) - t1.summedGraduates
from table as t
left join
(
select sum ( graduates ) summedGraduates, id
from table
where group_code not in ('total', 'others' )
group by id
) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates
Perhaps a better option would be to use SUM
with CASE
:
select sum(case when group_code = 'total' then graduates end) -
sum(case when group_code not in ('total','others') then graduates end)
from yourtable
In case something modifies the location that you're trying to serve, e.g. try_files
, this preserves the request for the back-end:
location / {
proxy_pass http://127.0.0.1:8080$request_uri;
}
Using the awesome Pillow library:
>>> from PIL import Image
>>> img = Image.open('test.png')
>>> img.show()
This will open the image in your default image viewer.
There may be other ways to get your desired result.
Declare @a int
Declare @b int
SET @a = 3
SET @b=2
SELECT cast((cast(@a as float)/ cast(@b as float)) as float)

Quirksmode had a post on this.
Since the page is now broken, and only accessible via archive.org, I reproduced it here:
IFrames
On this page I give a short overview of accessing iframes from the page they’re on. Not surprisingly, there are some browser considerations.
An iframe is an inline frame, a frame that, while containing a completely separate page with its own URL, is nonetheless placed inside another HTML page. This gives very nice possibilities in web design. The problem is to access the iframe, for instance to load a new page into it. This page explains how to do it.
Frame or object?
The fundamental question is whether the iframe is seen as a frame or as an object.
top.frames[1].frames[2]
and such). Does the iframe fit into this frame hierarchy?document.getElementById('theiframe'))
to access it.
In general browsers allow both views on 'real' (hard-coded) iframes, but generated iframes cannot be accessed as frames.NAME attribute
The most important rule is to give any iframe you create a name
attribute, even if you also use an id
.
<iframe src="iframe_page1.html"
id="testiframe"
name="testiframe"></iframe>
Most browsers need the name
attribute to make the iframe part of the frame hierarchy. Some browsers (notably Mozilla) need the id
to make the iframe accessible as an object. By assigning both attributes to the iframe you keep your options open. But name
is far more important than id
.
Access
Either you access the iframe as an object and change its src
or you access the iframe as a frame and change its location.href
.
document.getElementById('iframe_id').src = 'newpage.html'; frames['iframe_name'].location.href = 'newpage.html'; The frame syntax is slightly preferable because Opera 6 supports it but not the object syntax.
Accessing the iframe
So for a complete cross–browser experience you should give the iframe a name and use the
frames['testiframe'].location.href
syntax. As far as I know this always works.
Accessing the document
Accessing the document inside the iframe is quite simple, provided you use the name
attribute. To count the number of links in the document in the iframe, do
frames['testiframe'].document.links.length
.
Generated iframes
When you generate an iframe through the W3C DOM the iframe is not immediately entered into the frames
array, though, and the frames['testiframe'].location.href
syntax will not work right away. The browser needs a little time before the iframe turns up in the array, time during which no script may run.
The document.getElementById('testiframe').src
syntax works fine in all circumstances.
The target
attribute of a link doesn't work either with generated iframes, except in Opera, even though I gave my generated iframe both a name
and an id
.
The lack of target
support means that you must use JavaScript to change the content of a generated iframe, but since you need JavaScript anyway to generate it in the first place, I don't see this as much of a problem.
Text size in iframes
A curious Explorer 6 only bug:
When you change the text size through the View menu, text sizes in iframes are correctly changed. However, this browser does not change the line breaks in the original text, so that part of the text may become invisible, or line breaks may occur while the line could still hold another word.
Everyone has explained it greatly. But I wanted it to see it for myself. I use python3. So, I opened the resource monitor (in Windows!), and first, executed the following command first:
a=0
for i in range(1,100000):
a=a+i
and then checked the change in 'In Use' memory. It was insignificant. Then, I ran the following code:
for i in list(range(1,100000)):
a=a+i
And it took a big chunk of the memory for use, instantly. And, I was convinced. You can try it for yourself.
If you are using Python 2X, then replace 'range()' with 'xrange()' in the first code and 'list(range())' with 'range()'.
I'm having a hard time figuring out what exactly you're looking for here, so hope I'm not way off base.
I'm assuming what you mean is that when a keyup event occurs on the input with class "start" you want to get the values of all the inputs in neighbouring <td>s:
$('.start').keyup(function() {
var otherInputs = $(this).parents('td').siblings().find('input');
for(var i = 0; i < otherInputs.length; i++) {
alert($(otherInputs[i]).val());
}
return false;
});
Does it mean that I'm blocking reading any input from the Server/Client for this socket for 2000 millisecond and after this time the socket is ready to read data?
No, it means that if no data arrives within 2000ms a SocketTimeoutException
will be thrown.
What does it mean timeout expire?
It means the 2000ms (in your case) elapses without any data arriving.
What is the option which must be enabled prior to blocking operation?
There isn't one that 'must be' enabled. If you mean 'may be enabled', this is one of them.
Infinite Timeout menas that the socket does't read anymore?
What a strange suggestion. It means that if no data ever arrives you will block in the read forever.
You can use these steps to import the key to an existing keystore. The instructions are combined from answers in this thread and other sites. These instructions worked for me (the java keystore):
openssl pkcs12 -export -in yourserver.crt -inkey yourkey.key -out server.p12 -name somename -certfile yourca.crt -caname root
(If required put the -chain option. Putting that failed for me). This will ask for the password - you must give the correct password else you will get an error (heading error or padding error etc).
*.jks
file run:
keytool -importkeystore -srckeystore server.p12 -srcstoretype PKCS12
-destkeystore yourexistingjavakeystore.jks -deststoretype JKS -deststorepass existingjavastorepassword -destkeypass existingjavastorepassword
Try
<input type="number" pattern="^[0-9]" title='Only Number' min="1" step="1">
With a <script>
right after the <style>
that applies the !important
things, you should be able to do something like this:
var lastStylesheet = document.styleSheets[document.styleSheets.length - 1];
lastStylesheet.disabled = true;
document.write('<style type="text/css">');
// Call fixBackground for each element that needs fixing
document.write('</style>');
lastStylesheet.disabled = false;
function fixBackground(el) {
document.write('html #' + el.id + ' { background-image: ' +
document.defaultView.getComputedStyle(el).backgroundImage +
' !important; }');
}
This probably depends on what kind of browser compatibility you need, though.
Both works. Instead of ==
you can write eq
display: inline-block; will prevent break between the words in a list item
li {
display: inline-block;
}
I know this is a little late, but if someone else comes across this looking, you can now use public_path(); in Laravel 4, it has been added to the helper.php file in the support folder see here.
I am not a coder, but you could save a few lines:
<div>
<select onchange="if(selectedIndex!=0)document.getElementById('less_is_more').innerHTML=options[selectedIndex].value;">
<option value="">hire me for real estate</option>
<option value="me!!!">Who is a good Broker? </option>
<option value="yes!!!">Can I buy a house with no down payment</option>
<option value="send me a note!">Get my contact info?</option>
</select>
</div>
<div id="less_is_more"></div>
Here is demo.
In your first example, you are making a blank array, same as doing var x = []
. The 2nd example makes an array of size 3 (with all elements undefined
). The 3rd and 4th examples are the same, they both make arrays with those elements.
Be careful when using new Array()
.
var x = new Array(10); // array of size 10, all elements undefined
var y = new Array(10, 5); // array of size 2: [10, 5]
The preferred way is using the []
syntax.
var x = []; // array of size 0
var y = [10] // array of size 1: [1]
var z = []; // array of size 0
z[2] = 12; // z is now size 3: [undefined, undefined, 12]
As Mark C points out, you can use the MSXML Base64 encoding functionality as described here.
I prefer late binding because it's easier to deploy, so here's the same function that will work without any VBA references:
Function EncodeBase64(text As String) As String
Dim arrData() As Byte
arrData = StrConv(text, vbFromUnicode)
Dim objXML As Variant
Dim objNode As Variant
Set objXML = CreateObject("MSXML2.DOMDocument")
Set objNode = objXML.createElement("b64")
objNode.dataType = "bin.base64"
objNode.nodeTypedValue = arrData
EncodeBase64 = objNode.text
Set objNode = Nothing
Set objXML = Nothing
End Function
I had a similar problem: git diff
would show differences, but git diff <filename>
would not. It turned out that I set LESS
to a string including -F
(--quit-if-one-screen
). Removing that flag solved the problem.
array_search('20120504', array_keys($your_array));
Simple use this great free online tool:
The below is a little slow, but it gives a nicely formatted list of packages that pip
is aware of. That is to say, not all of them were installed "by" pip, but all of them should be able to be upgraded by pip.
$ pip search . | egrep -B1 'INSTALLED|LATEST'
The reason it is slow is that it lists the contents of the entire pypi repo. I filed a ticket suggesting pip list
provide similar functionality but more efficiently.
Sample output: (restricted the search to a subset instead of '.' for all.)
$ pip search selenium | egrep -B1 'INSTALLED|LATEST'

Some reading to get you started on character encodings: Joel on Software: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)
By the way - ASP.NET has nothing to do with it. Encodings are universal.
For example 5 consecutive numbers
int largestNumber;
int smallestNumber;
int number;
std::cin>>number;
largestNumber = number;
smallestNumber = number;
for (i=0 ; i<5; i++)
{
std::cin>>number;
if (number > largestNumber)
{
largest = number;
}
if (numbers < smallestNumber)
{
smallestNumber= number;
}
}
This can be solved also by izip
ping the dataframe (iterator) with an offset version of itself.
Of course the indexing error cannot be reproduced this way.
Check this out
import pandas as pd
from itertools import izip
df = pd.DataFrame(['AA', 'BB', 'CC'], columns = ['value'])
for id1, id2 in izip(df.iterrows(),df.ix[1:].iterrows()):
print id1[1]['value']
print id2[1]['value']
which gives
AA
BB
BB
CC
On newer versions of yum, this information is stored in the "yumdb" when the package is installed. This is the only 100% accurate way to get the information, and you can use:
yumdb search from_repo repoid
(or repoquery and grep -- don't grep yum output). However the command "find-repos-of-install" was part of yum-utils for a while which did the best guess without that information:
http://james.fedorapeople.org/yum/commands/find-repos-of-install.py
As floyd said, a lot of repos. include a unique "dist" tag in their release, and you can look for that ... however from what you said, I guess that isn't the case for you?
I tried joonty's answer, but I also got the
exec: 1: not found
error. This is what works best for me (confirmed to work in zsh also):
#!/bin/bash
LOG_FILE=/tmp/both.log
exec > >(tee ${LOG_FILE}) 2>&1
echo "this is stdout"
chmmm 77 /makeError
The file /tmp/both.log afterwards contains
this is stdout
chmmm command not found
The /tmp/both.log is appended unless you remove the -a from tee.
Hint: >(...)
is a process substitution. It lets the exec
to the tee
command as if it were a file.
Use input.nextLine();
instead of input.next();

In WPF, TextBox element will not get opportunity to use "Enter" button for creating KeyUp Event until you will not set property: AcceptsReturn="True".
But, it would`t solve the problem with handling KeyUp Event in TextBox element. After pressing "ENTER" you will get a new text line in TextBox.
I had solved problem of using KeyUp Event of TextBox element by using Bubble event strategy. It's short and easy. You have to attach a KeyUp Event handler in some (any) parent element:

<TextBlock Name="txtBlock" Grid.Row="5" Grid.Column="1" HorizontalAlignment="Stretch"/>
</Grid></Window>
C# logical part (KeyUp Event handler is attached to a grid element):

InitializeComponent();
}
private void Grid_KeyUp(object sender, KeyEventArgs e)
{
if(e.Key == Key.Enter)

}
}
Result:
In my case, the issue occurred after I switched from a git branch to another, references to some old files remained in the scripts inside "node_modules/.cache" directory.
Deleting "node_modules", "build" directories and "package-lock.json" file then issuing "npm install" command has fixed the issue for me
This issue is happening due to change of protocol from http to https for central repository. please refer following link for more details. https://support.sonatype.com/hc/en-us/articles/360041287334-Central-501-HTTPS-Required
In order to fix the problem, copy following into your pom.ml file. This will set the repository url to use https.

This will download all the Debs to the current directory, and will NOT fail if It can't find a candidate.
Also does NOT require sudo to run sript!
nano getdebs.sh && chmod +x getdebs.sh && ./getdebs.sh
#!/bin/bash
package=ssmtp
apt-cache depends "$package" | grep Depends: >> deb.list
sed -i -e 's/[<>|:]//g' deb.list
sed -i -e 's/Depends//g' deb.list
sed -i -e 's/ //g' deb.list
filename="deb.list"
while read -r line
do
name="$line"
apt-get download "$name"
done < "$filename"
apt-get download "$package"
Note: I used this as my example because I was actually trying to DL the Deps for SSMTP and it failed on debconf-2.0, but this script got me what I need! Hope it helps.
A minor update to this: a sender should never set the Return-Path:
header. There's no such thing as a Return-Path:
header for a message in transit. That header is set by the MTA that makes final delivery, and is generally set to the value of the 5321.From
unless the local system needs some kind of quirky routing.
It's a common misunderstanding because users rarely see an email without a Return-Path:
header in their mailboxes. This is because they always see delivered messages, but an MTA should never see a Return-Path:
header on a message in transit. See http://tools.ietf.org/html/rfc5321#section-4.4
The source for this answer is the comment to the answer at: Will docker container auto sync time with the host machine?
After looking at the answer, I realized that there is no way a clock drift will occur on the docker container. Docker uses the same clock as the host and the docker cannot change it. It means that doing an ntpdate
inside the docker does not work.
The correct thing to do is to update the host time using ntpdate
As far as syncing timezones is concerned, -v /etc/localtime:/etc/localtime:ro
works.
Launch the Terminal application and enter the following command after the prompt
openssl pkcs12 -in CertificateName.p12 -out CertificateName.pem -nodes
This what helped me:
List<RepositoryFile> fileList = response.getRepositoryFileList();
RepositoryFile file1 = fileList.stream().filter(f -> f.getName().contains("my-file.txt")).findFirst().orElse(null);

First, concurrent version control seems like an easy problem to solve. It's not at all. Anyway...
SVN is quite non-intuitive. Git is even worse. [sarcastic-speculation] This might be because developers, that like hard problems like concurrent version control, don't have much interest in making a good UI. [/sarcastic-speculation]
SVN supporters think they don't need a distributed version-control system. I thought that too. But now that we use Git exclusively, I'm a believer. Now version control works for me AND the team/project instead of just working for the project. When I need a branch, I branch. Sometimes it's a branch that has a corresponding branch on the server, and sometimes it does not. Not to mention all the other advantages that I'll have to go study up on (thanks in part to the arcane and absurd lack of UI that is a modern version control system).
Here is a full example of what you are looking for:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script>
$( document ).ready(function() {
$("#providersFormElementsTable").html("<tr><td>Nickname</td><td><input type='text' id='nickname' name='nickname'></td></tr><tr><td>CA Number</td><td><input type='text' id='account' name='account'></td></tr>");
});
</script>
</head>
<body>
<table border="0" cellpadding="0" width="100%" id='providersFormElementsTable'> </table>
</body>
I would suggest you to use fseek-ftell functions.
FILE *stream = fopen("example.txt", "r");
if(!stream) {
puts("I/O error.\n");
return;
}
fseek(stream, 0, SEEK_END);
long size = ftell(stream);
fseek(stream, 0, SEEK_SET);
while(1) {
if(ftell(stream) == size) {
break;
}
/* INSERT ROUTINE */
}
fclose(stream);
This is to supplement zerkms's answer.
To pass data across language barriers, you would need a way to represent the data as a string by serializing the data. One of the serialization methods for JavaScript is JSON. In zerkms's example, the code would be placed inside of an aspx page. To combine his example and yours together on one aspx page, you would have,
<%
int[] numbers = new int[5];
// Fill up numbers...
var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
%>
somewhere later on the aspx page
<script type="text/javascript">
var jsVariable = <%= serializer.Serialize(numbers) %>;
</script>
This answer though, assumes that you are generating JavaScript from the initial page load. As per the comments in your post, this could have been done via AJAX. In that case, you would have the server respond with the result of the serialization and then deserialize it in JavaScript using your favorite framework.
Note: Also do not mark this as an answer since I wanted the syntax highlighting to make another answer more clear.
SIMPLY, You must set initial state first
If you don't set initial state react will treat that as an uncontrolled component
Use this in your code:
String.valueOf(x);
You have 3 options: Chrome (via Developer Tools -> Network tab), Wireshark, and Fiddler (via Log tab), however they all very basic. If you have very high volume of traffic or each frame is very large, it becomes very difficult to use them for debugging.
You can however use Fiddler with FiddlerScript to inspect WebSocket traffic in the same way you inpect HTTP traffic. Few advantages of this solution are that you can leverage many other functionalities in Fiddler, such as multiple inspectors (HexView, JSON, SyntaxView), compare packets, and find packets, etc.
Please refer to my recently written article on CodeProject, which show you how to Debug/Inspect WebSocket traffic with Fiddler (with FiddlerScript). http://www.codeproject.com/Articles/718660/Debug-Inspect-WebSocket-traffic-with-Fiddler
Literal Answer -- warning, performance may not be as good as just using an int
to track the index. At least it is better than using IndexOf
.
You just need to use the indexing overload of Select to wrap each item in the collection with an anonymous object that knows the index. This can be done against anything that implements IEnumerable.
System.Collections.IEnumerable collection = Enumerable.Range(100, 10);
foreach (var o in collection.OfType<object>().Select((x, i) => new {x, i}))
{
Console.WriteLine("{0} {1}", o.i, o.x);
}
The best method would be using some JSON library, e.g. Jackson ( http://jackson.codehaus.org ).
But if this is not an option simply escape msget before adding it to your string:
The wrong way to do this is
String msgetEscaped = msget.replaceAll("\"", "\\\"");
Either use (as recommended in the comments)
String msgetEscaped = msget.replace("\"", "\\\"");
or
String msgetEscaped = msget.replaceAll("\"", "\\\\\"");
A sample with all three variants can be found here: http://ideone.com/Nt1XzO
I came across the same problem. I properly installed the MYSQL Workbench 6.x, but faced the connection as below:
I did a bit R&D on this and found that MySQL service in service.msc is not present. To achieve this I created a new connection in MySQL Workbench then manually configured the MySQL Database Server in "System Profile" (see the below picture).
You also need to install MySQL Database Server and set a configuration file path for my.ini
. Now at last test the connection (make sure MySQL service is running in services.msc).
Here's what I did:
That's it. I have tested it with my Nokia and it's working for me.
This solution meets the following criteria
As far as I'm aware, this criteria cannot be met without Javascript (unfortunately).
This solution uses jQuery, but could also be easily converted to vanilla JS:
function fixedHeader(){_x000D_
$(this).width($("#wrapper").width());_x000D_
$("#header-filler").height($("#header-fixed").outerHeight());_x000D_
}_x000D_
_x000D_
$(window).resize(function() {_x000D_
fixedHeader();_x000D_
});_x000D_
_x000D_
fixedHeader();
_x000D_
#header-fixed{_x000D_

In order to refresh a table layout (TableLayout) I ended up having to use the recursive approach mentioned above to get all the children's children and so forth.
My situation was somewhat simplified because I only needed to work with LinearLayout and those classes extended from it such as TableLayout. And I was only interested in finding TextView children. But I think it's still applicable to this question.
The final class runs as a separate thread, which means it can do other things in the background before parsing for the children. The code is small and simple and can be found at github: https://github.com/jkincali/Android-LinearLayout-Parser
This way worked for me when adding random data to MySql table using a python script.
First install the following packages using the below commands
pip install mysql-connector-python<br>
pip install random
import mysql.connector
import random
from datetime import date
start_dt = date.today().replace(day=1, month=1).toordinal()
end_dt = date.today().toordinal()
mydb = mysql.connector.connect(
host="localhost",
user="root",
password="root",
database="your_db_name"
)
mycursor = mydb.cursor()
sql_insertion = "INSERT INTO customer (name,email,address,dateJoined) VALUES (%s, %s,%s, %s)"
#insert 10 records(rows)
for x in range(1,11):
#generate a random date
random_day = date.fromordinal(random.randint(start_dt, end_dt))
value = ("customer" + str(x),"customer_email" + str(x),"customer_address" + str(x),random_day)
mycursor.execute(sql_insertion , value)
mydb.commit()
print("customer records inserted!")
Following is a sample output of the insertion
cid | name | email | address | dateJoined |
1 | customer1 | customer_email1 | customer_address1 | 2020-11-15 |
2 | customer2 | customer_email2 | customer_address2 | 2020-10-11 |
3 | customer3 | customer_email3 | customer_address3 | 2020-11-17 |
4 | customer4 | customer_email4 | customer_address4 | 2020-09-20 |
5 | customer5 | customer_email5 | customer_address5 | 2020-02-18 |
6 | customer6 | customer_email6 | customer_address6 | 2020-01-11 |
7 | customer7 | customer_email7 | customer_address7 | 2020-05-30 |
8 | customer8 | customer_email8 | customer_address8 | 2020-04-22 |
9 | customer9 | customer_email9 | customer_address9 | 2020-01-05 |
10 | customer10 | customer_email10| customer_address10| 2020-11-12 |
PyLibTiff worked better for me than PIL, which as of December 2020 still doesn't support color images with more than 8 bits per color.
from libtiff import TIFF
tif = TIFF.open('filename.tif') # open tiff file in read mode
# read an image in the currect TIFF directory as a numpy array
image = tif.read_image()
# read all images in a TIFF file:
for image in tif.iter_images():
pass
tif = TIFF.open('filename.tif', mode='w')
tif.write_image(image)
You can install PyLibTiff with
pip3 install numpy libtiff
The readme of PyLibTiff also mentions the tifffile
library but I haven't tried it.
sudo PATH="$PATH:/usr/local/bin" npm install -g <package-name>
A simple way is to check the version by typing psql --version
in terminal
Use DATESTR
>> datestr(40189)
ans =
12-Jan-0110
Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM
>> datenum(2010,1,11)
ans =
734149
>> datenum(2010,1,11)-40189
ans =
693960
>> datestr(40189+693960)
ans =
11-Jan-2010
In other words, to convert any serial Excel date, call
datestr(excelSerialDate + 693960)
EDIT
To get the date in mm/dd/yyyy format, call datestr
with the specified format
excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010
Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things
excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010
shell_exec
- Execute command via shell and return the complete output as a string
exec
- Execute an external program.
The difference is that with shell_exec
you get output as a return value.
There are two elements in array and this definitely doesn't mean that array is empty. As a quick workaround you can do following:
$errors = array_filter($errors);
if (!empty($errors)) {
}
array_filter()
function's default behavior will remove all values from array which are equal to null
, 0
, ''
or false
.
Otherwise in your particular case empty()
construct will always return true
if there is at least one element even with "empty" value.
There are different papers on both sites, I think that you only need to choose your side. Personally I prefer Plurar for tables naming, and of course singular for column naming.
I like how you can read this:
SELECT CustomerName FROM Customers WHERE CustomerID = 100;
Really we have OOP, and is great, but most people keep using Relational Databases, no Object Databases. There is no need to follow the OOP concepts for Relational Databases.
Another example, you have a table Teams, that keep TeamID, TeamColor but also PlayerID, and will have same teamID and TeamColor for certain amount of PlayerID...
To Which team the player belongs?
SELECT * FROM Teams WHERE PlayerID = X
All Players from X Team?
SELECT * FROM Players INNER JOIN Teams ON Players.PlayerID = Teams.PlayerID WHERE Teams.TeamID = X
All this sound good to you?
Anyways, also take a look to naming conventions used by W3Schools:
I recently came across Python 3 interpreter at CompileOnline.
Unfortunately @BrianFreud's answer doesn't fit my needs, I had a little different need, and I know that is not the answer for @BrianFreud's question, but I am leaving it here because a lot of persons got here with my same need. I needed something like 'How to get a file or blob from an URL?', and the current correct answer does not fit my needs because its not cross-domain.
I have a website that consumes images from an Amazon S3/Azure Storage, and there I store objects named with uniqueidentifiers:
sample: http://****.blob.core.windows.net/systemimages/bf142dc9-0185-4aee-a3f4-1e5e95a09bcf
Some of this images should be download from our system interface. To avoid passing this traffic through my HTTP server, since this objects does not require any security to be accessed (except by domain filtering), I decided to make a direct request on user's browser and use local processing to give the file a real name and extension.
To accomplish that I have used this great article from Henry Algus: http://www.henryalgus.com/reading-binary-files-using-jquery-ajax/
1. First step: Add binary support to jquery
/**
*
* jquery.binarytransport.js
*
* @description. jQuery ajax transport for making binary data type requests.
* @version 1.0
* @author Henry Algus <[email protected]>
*
*/
// use this transport for "binary" data type
$.ajaxTransport("+binary", function (options, originalOptions, jqXHR) {
// check for conditions and support for blob / arraybuffer response type
if (window.FormData && ((options.dataType && (options.dataType == 'binary')) || (options.data && ((window.ArrayBuffer && options.data instanceof ArrayBuffer) || (window.Blob && options.data instanceof Blob))))) {
return {
// create new XMLHttpRequest
send: function (headers, callback) {
// setup all variables
var xhr = new XMLHttpRequest(),
url = options.url,
type = options.type,
async = options.async || true,
// blob or arraybuffer. Default is blob
dataType = options.responseType || "blob",
data = options.data || null,
username = options.username || null,
password = options.password || null;
xhr.addEventListener('load', function () {
var data = {};
data[options.dataType] = xhr.response;
// make callback and send data
callback(xhr.status, xhr.statusText, data, xhr.getAllResponseHeaders());
});
xhr.open(type, url, async, username, password);
// setup custom headers
for (var i in headers) {
xhr.setRequestHeader(i, headers[i]);
}
xhr.responseType = dataType;
xhr.send(data);
},
abort: function () {
jqXHR.abort();
}
};
}
});
2. Second step: Make a request using this transport type.
function downloadArt(url)
{
$.ajax(url, {
dataType: "binary",
processData: false
}).done(function (data) {
// just my logic to name/create files
var filename = url.substr(url.lastIndexOf('/') + 1) + '.png';
var blob = new Blob([data], { type: 'image/png' });
saveAs(blob, filename);
});
}
Now you can use the Blob created as you want to, in my case I want to save it to disk.
3. Optional: Save file on user's computer using FileSaver
I have used FileSaver.js to save to disk the downloaded file, if you need to accomplish that, please use this javascript library:
https://github.com/eligrey/FileSaver.js/
I expect this to help others with more specific needs.
Simple workaround - just use hidden field as placeholder for select, checkbox and radio.
From this code to -
<form action="/Media/Add">
<input type="hidden" name="Id" value="123" />
<!-- this does not appear in request -->
<input type="textbox" name="Percentage" value="100" disabled="disabled" />
<select name="gender" disabled="disabled">
<option value="male">Male</option>
<option value="female" selected>Female</option>
</select>
</form>
that code -
<form action="/Media/Add">
<input type="hidden" name="Id" value="123" />
<input type="textbox" value="100" readonly />
<input type="hidden" name="gender" value="female" />
<select name="gender" disabled="disabled">
<option value="male">Male</option>
<option value="female" selected>Female</option>
</select>
</form>
This may be an old thread but I came across it and figured that I would give a final answer.
The twitch api is json based and to recieve your stream key you need to authorize your app for use with the api. You do so under the connections tab within your profile on twitch.tv itself.. Down the bottom of said tab there is "register your app" or something similar. Register it and you'll get a client-id header for your get requests.
Now you need to attach your Oauthv2 key to your headers or as a param during the query to the following get request.
curl -H 'Accept: application/vnd.twitchtv.v3+json' -H 'Authorization: OAuth ' \ -X GET https://api.twitch.tv/kraken/channel
As you can see in the documentation above, if you've done these two things, your stream key will be made available to you.
As I said - Sorry for the bump but some people do find it hard to read the twitch* api.
Hope that helps somebody in the future.
I see you have a problem. Try building your app as Release and then check out your source codes build folder. It may be called Release-iphonesimulator. Inside here will be the app. Then go to (home folder)/Library/Application Support/iPhone Simulator (if you can't find it, try pressing Command - J and choosing arrange by name). Go to an OS that has apps in it in the iPhone sim, like 4.1. In that folder there should be an Applications folder. Open that, and there should be folders with random lettering. Pick any one, and replace it with the app you have. Make sure to delete anything in the little folders!
If it doesn't work, then I'm dumbfounded.
Alternative solution (you can replace createElement with a your own element)
var mvar = $('.mbox').wrapAll(document.createElement('div')).closest('div').text();
console.log(mvar);
When I add @ComponentScan("com.firstday.spring.boot.services")
or scanBasePackages{"com.firstday.spring.boot.services"}
jsp is not loaded. So when I add the parent package of project in @SpringBootApplication class it's working fine in my case
Code Example:-
package com.firstday.spring.boot.firstday;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication(scanBasePackages = {"com.firstday.spring.boot"})
public class FirstDayApplication {
public static void main(String[] args) {
SpringApplication.run(FirstDayApplication.class, args);
}
}
Yes you can upload your git repo from vs code. You have to get in the projects working directory and type git init in the terminal. Then add the files to your repository like you do with regular git commits.

There is an example in the launcher app of Android (that I've made a library out of it, here), inside the class that handles wallpapers-picking ("WallpaperPickerActivity") .
The example shows that you need to set a customized theme for this to work. Sadly, this worked for me only using the normal framework, and not the one of the support library.
Here're the themes:
styles.xml
<style name="Theme.WallpaperPicker" parent="Theme.WallpaperCropper">
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:colorBackgroundCacheHint">@null</item>
<item name="android:windowShowWallpaper">true</item>
</style>
<style name="Theme.WallpaperCropper" parent="@android:style/Theme.DeviceDefault">
<item name="android:actionBarStyle">@style/WallpaperCropperActionBar</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowActionBarOverlay">true</item>
</style>
<style name="WallpaperCropperActionBar" parent="@android:style/Widget.DeviceDefault.ActionBar">
<item name="android:displayOptions">showCustom</item>
<item name="android:background">#88000000</item>
</style>
value-v19/styles.xml
<style name="Theme.WallpaperCropper" parent="@android:style/Theme.DeviceDefault">
<item name="android:actionBarStyle">@style/WallpaperCropperActionBar</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
<style name="Theme" parent="@android:style/Theme.DeviceDefault.Wallpaper.NoTitleBar">
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
EDIT: there is a better way to do it, which works on the support library too. Just add this line of code instead of what I've written above:
getSupportActionBar().setDisplayShowCustomEnabled(true);
update: in the comments, Goerge says " This works on Chrome, Firefox and Edge, but not Safari."
This is the W3C solution. You can use it in 3012!
ul { list-style-type: "*"; } /* Sets the marker to a "star" character */
This is not an error, it is a warning from your Microsoft compiler.
Select your project and click "Properties" in the context menu.
In the dialog, chose Configuration Properties
-> C/C++
-> Preprocessor
In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS
to turn those warnings off.
I think max value of int(11) is 4294967295
Create an xml file in your drawable like this :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_enabled="false"
android:drawable="@drawable/btn_sendemail_disable" />
<item
android:state_pressed="true"
android:state_enabled="true"
android:drawable="@drawable/btn_send_email_click" />
<item
android:state_focused="true"
android:state_enabled="true"
android:drawable="@drawable/btn_sendemail_roll" />
<item
android:state_enabled="true"
android:drawable="@drawable/btn_sendemail" />
</selector>
And set images accordingly and then set this xml as background of your imageButton
.
Simply do the following in didFinishWithLaunching:
:
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: []) { _, _ in
application.registerForRemoteNotifications()
}
}
Remember about import statement:
import UserNotifications
Just use Kotlin!
val list = listOf(user1, user2, user3)
val maxDate = list.maxBy { it.date }?.date
Did you try this tip?
Or better still, use ipython, and call:
from IPython.Debugger import Tracer; debug_here = Tracer()
then you can just use
debug_here()
whenever you want to set a breakpoint
Add the below declarations to your class:
public const SslProtocols _Tls12 = (SslProtocols)0x00000C00;
public const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
After:
var client = new HttpClient();
And:
ServicePointManager.SecurityProtocol = Tls12;
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 /*| SecurityProtocolType.Tls */| Tls12;
Happy? :)

/* call ajax here... on success enable scroll */_x000D_
$('.posts').append('<h4>' + (++c) + ' </h4>' + t);_x000D_

how to have a click event outside of the dropdown menu so that it close the dropdown menu ? Heres the code
$(document).click(function (e) {
e.stopPropagation();
var container = $(".dropDown");
//check if the clicked area is dropDown or not
if (container.has(e.target).length === 0) {
$('.subMenu').hide();
}
})
Try this...
SELECT TO_CHAR(column_name,'99G999D99MI')
as format_column
FROM DUAL;
You are correct, @RequestBody annotated parameter is expected to hold the entire body of the request and bind to one object, so you essentially will have to go with your options.
If you absolutely want your approach, there is a custom implementation that you can do though:
Say this is your json:
{
"str1": "test one",
"str2": "two test"
}
and you want to bind it to the two params here:
@RequestMapping(value = "/Test", method = RequestMethod.POST)
public boolean getTest(String str1, String str2)
First define a custom annotation, say @JsonArg
, with the JSON path like path to the information that you want:
public boolean getTest(@JsonArg("/str1") String str1, @JsonArg("/str2") String str2)
Now write a Custom HandlerMethodArgumentResolver which uses the JsonPath defined above to resolve the actual argument:
import java.io.IOException;
import javax.servlet.http.HttpServletRequest;
import org.apache.commons.io.IOUtils;
import org.springframework.core.MethodParameter;
import org.springframework.http.server.ServletServerHttpRequest;
import org.springframework.web.bind.support.WebDataBinderFactory;
import org.springframework.web.context.request.NativeWebRequest;
import org.springframework.web.method.support.HandlerMethodArgumentResolver;
import org.springframework.web.method.support.ModelAndViewContainer;
import com.jayway.jsonpath.JsonPath;
public class JsonPathArgumentResolver implements HandlerMethodArgumentResolver{
private static final String JSONBODYATTRIBUTE = "JSON_REQUEST_BODY";
@Override
public boolean supportsParameter(MethodParameter parameter) {
return parameter.hasParameterAnnotation(JsonArg.class);
}
@Override
public Object resolveArgument(MethodParameter parameter, ModelAndViewContainer mavContainer, NativeWebRequest webRequest, WebDataBinderFactory binderFactory) throws Exception {
String body = getRequestBody(webRequest);
String val = JsonPath.read(body, parameter.getMethodAnnotation(JsonArg.class).value());
return val;
}
private String getRequestBody(NativeWebRequest webRequest){
HttpServletRequest servletRequest = webRequest.getNativeRequest(HttpServletRequest.class);
String jsonBody = (String) servletRequest.getAttribute(JSONBODYATTRIBUTE);
if (jsonBody==null){
try {
String body = IOUtils.toString(servletRequest.getInputStream());
servletRequest.setAttribute(JSONBODYATTRIBUTE, body);
return body;
} catch (IOException e) {
throw new RuntimeException(e);
}
}
return "";
}
}
Now just register this with Spring MVC. A bit involved, but this should work cleanly.
Using modern --inspect with node the console.log is captured and relayed to the browser.
node --inspect myApp.js
or to capture early logging --inspect-brk can be used to stop the program on the first line of the first module...
node --inspect-brk myApp.js
I'll also prefer ALTER LOGIN
Command as in accepted answer and described here
But for GUI lover
Tired of reading!!! just look at following
For the sake of completeness, there is also a data.table
solution:
library(data.table)
result <- setDT(df)[, paste0(names(df), "_length") := lapply(.SD, stringr::str_length)]
result
# col1 col2 col1_length col2_length
#1: abc adf qqwe 3 8
#2: abcd d 4 1
#3: a e 1 1
#4: abcdefg f 7 1
Using Math.Round()
:
int percentComplete = (int)Math.Round((double)(100 * complete) / total);
or manually rounding:
int percentComplete = (int)(0.5f + ((100f * complete) / total));
Although this is an old document, but it helped me resolve the problem of 'HintPath' being ignored on another machine. It was because the referenced DLL needed to be in source control as well:
Excerpt:
To include and then reference an outer-system assembly 1. In Solution Explorer, right-click the project that needs to reference the assembly,,and then click Add Existing Item. 2. Browse to the assembly, and then click OK. The assembly is then copied into the project folder and automatically added to VSS (assuming the project is already under source control). 3. Use the Browse button in the Add Reference dialog box to set a file reference to assembly in the project folder.
Trying to access an undefined variable will throw you a ReferenceError
.
A solution to this is to use typeof
:
if (typeof window === "undefined") {
console.log("Oops, `window` is not defined")
}
or a try catch:
try { window } catch (err) {
console.log("Oops, `window` is not defined")
}
While typeof window
is probably the cleanest of the two, the try catch can still be useful in some cases.
