So is there any other method to achieve this goal?
No. In order to convert an image to a byte array you have to specify an image format - just as you have to specify an encoding when you convert text to a byte array.
If you're worried about compression artefacts, pick a lossless format. If you're worried about CPU resources, pick a format which doesn't bother compressing - just raw ARGB pixels, for example. But of course that will lead to a larger byte array.
Note that if you pick a format which does include compression, there's no point in then compressing the byte array afterwards - it's almost certain to have no beneficial effect.
I'm using tesseract OCR engine with TessNet2 (a C# wrapper - http://www.pixel-technology.com/freeware/tessnet2/).
Some basic code:
using tessnet2;
...
Bitmap image = new Bitmap(@"u:\user files\bwalker\2849257.tif");
tessnet2.Tesseract ocr = new tessnet2.Tesseract();
ocr.SetVariable("tessedit_char_whitelist", "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.,$-/#&=()\"':?"); // Accepted characters
ocr.Init(@"C:\Users\bwalker\Documents\Visual Studio 2010\Projects\tessnetWinForms\tessnetWinForms\bin\Release\", "eng", false); // Directory of your tessdata folder
List<tessnet2.Word> result = ocr.DoOCR(image, System.Drawing.Rectangle.Empty);
string Results = "";
foreach (tessnet2.Word word in result)
{
Results += word.Confidence + ", " + word.Text + ", " + word.Left + ", " + word.Top + ", " + word.Bottom + ", " + word.Right + "\n";
}
Install-Package System.Drawing.Common
You can try something like this:
Image logo = Image.GetInstance("pathToTheImage")
logo.ScaleAbsolute(500, 300)
"I want a Bitmap d, that is grayscale. I do see a consructor that includes System.Drawing.Imaging.PixelFormat, but I don't understand how to use that."
Here is how to do this
Bitmap grayScaleBP = new
System.Drawing.Bitmap(2, 2, System.Drawing.Imaging.PixelFormat.Format16bppGrayScale);
EDIT: To convert to grayscale
Bitmap c = new Bitmap("fromFile");
Bitmap d;
int x, y;
// Loop through the images pixels to reset color.
for (x = 0; x < c.Width; x++)
{
for (y = 0; y < c.Height; y++)
{
Color pixelColor = c.GetPixel(x, y);
Color newColor = Color.FromArgb(pixelColor.R, 0, 0);
c.SetPixel(x, y, newColor); // Now greyscale
}
}
d = c; // d is grayscale version of c

Try Stretch="UniformToFill" on the Image
You should give the new monkeyrunner a go. Maybe this can solve your problems. You put keycodes in it for testing, maybe touch events are also possible.
Check out Setting Up Google Play Services which says:
To develop an app using the Google Play services APIs, you need to set up your project with the Google Play services SDK.
If you haven't installed the Google Play services SDK yet, go get it now by following the guide to Adding SDK Packages.
To test your app when using the Google Play services SDK, you must use either:
- A compatible Android device that runs Android 2.3 or higher and includes Google Play Store.
- The Android emulator with an AVD that runs the Google APIs platform based on Android 4.2.2 or higher.

Server.UrlEncode() is there to provide backward compatibility with Classic ASP,
Server.UrlEncode(str);
Is equivalent to:
HttpUtility.UrlEncode(str, Response.ContentEncoding);
Note: This solution changes based on viewport size and not the amount of content
I just found out that this is possible using VW units. They're the units associated with setting the viewport width. There are some drawbacks, such as lack of legacy browser support, but this is definitely something to seriously consider using. Plus you can still provide fallbacks for older browsers like so:
p {
font-size: 30px;
font-size: 3.5vw;
}

Even if that's a 7 years old question, people new to R should consider using the data.table, package.
A data.table is a data.frame so all you can do for/to a data.frame you can also do. But many think are ORDERS of magnitude faster with data.table.
vec <- 1:10
library(data.table)
DT <- data.table(start=c(1,3,5,7), end=c(2,6,7,9))
DT[,new:=apply(DT,1,function(row) mean(vec[ row[1] : row[2] ] ))]

String result = "";
LinkedListNode current = head;
while(current.getNext() != null){

I found the following removed the indent and the margin from both the left AND right sides, but allowed the bullets to remain left-justified below the text above it. Add this to your css file:
ul.noindent {
margin-left: 5px;
margin-right: 0px;
padding-left: 10px;
padding-right: 0px;
}
To use it in your html file add class="noindent" to the UL tag. I've tested w/FF 14 and IE 9.
I have no idea why browsers default to the indents, but I haven't really had a reason for changing them that often.

cardView.setCardBackgroundColor(0xFFFEFEFE);

I am calling different validation classes for Store and Update. In my case I don't want to update every fields, so I have baseRules for common fields for Create and Edit. Add extra validation classes for each. I hope my example is helpful. I am using Laravel 4.
Model:
public static $baseRules = array(
'first_name' => 'required',
'last_name' => 'required',
'description' => 'required',
'description2' => 'required',
'phone' => 'required | numeric',
'video_link' => 'required | url',
'video_title' => 'required | max:87',
'video_description' => 'required',
'sex' => 'in:M,F,B',
'title' => 'required'
);
public static function validate($data)
{
$createRule = static::$baseRules;
$createRule['email'] = 'required | email | unique:musicians';
$createRule['band'] = 'required | unique:musicians';
$createRule['style'] = 'required';
$createRule['instrument'] = 'required';
$createRule['myFile'] = 'required | image';
return Validator::make($data, $createRule);
}
public static function validateUpdate($data, $id)
{
$updateRule = static::$baseRules;
$updateRule['email'] = 'required | email | unique:musicians,email,' . $id;
$updateRule['band'] = 'required | unique:musicians,band,' . $id;
return Validator::make($data, $updateRule);
}

->withErrors($validation, 'musicain')
->withInput();
}
}

Here is a base R answer using aggregate
and ave
:
df1 <- with(mtcars, aggregate(list(n = mpg), list(am = am, gear = gear), length))
df1$prop <- with(df1, n/ave(n, am, FUN = sum))
#Also with prop.table
#df1$prop <- with(df1, ave(n, am, FUN = prop.table))
df1
# am gear n prop
#1 0 3 15 0.7894737
#2 0 4 4 0.2105263
#3 1 4 8 0.6153846
#4 1 5 5 0.3846154
We can also use prop.table
but the output displays differently.
prop.table(table(mtcars$am, mtcars$gear), 1)
# 3 4 5
# 0 0.7894737 0.2105263 0.0000000
# 1 0.0000000 0.6153846 0.3846154

To set the color of a font, you must first initialize the color by doing this:
Color maroon = new Color (128, 0, 0);
Once you've done that, you then put:
Font font = new Font ("Courier New", 1, 25); //Initializes the font
c.setColor (maroon); //Sets the color of the font
c.setFont (font); //Sets the font
c.drawString ("Your text here", locationX, locationY); //Outputs the string
Note: The 1 represents the type of font and this can be used to replace Font.PLAIN and the 25 represents the size of your font.

I was having some issues using the above solutions with an "associative array" type object. These solutions seem to preserve the values, but they do not preserve the actual names of the objects that those values are associated with, which can cause some issues. So I put together the following functions which I am using instead:
function flattenAssocArr(object) {
if(typeof object == "object") {
var keys = [];
keys[0] = "ASSOCARR";
keys.push(...Object.keys(object));
var outArr = [];
outArr[0] = keys;
for(var i = 1; i < keys.length; i++) {
outArr[i] = flattenAssocArr(object[keys[i]])
}
return outArr;
} else {
return object;
}
}
function expandAssocArr(object) {
if(typeof object !== "object")
return object;
var keys = object[0];
var newObj = new Object();
if(keys[0] === "ASSOCARR") {
for(var i = 1; i < keys.length; i++) {
newObj[keys[i]] = expandAssocArr(object[i])
}
}
return newObj;
}
Note that these can't be used with any arbitrary object -- basically it creates a new array, stores the keys as element 0, with the data following it. So if you try to load an array that isn't created with these functions having element 0 as a key list, the results might be...interesting :)
I'm using it like this:
var objAsString = JSON.stringify(flattenAssocArr(globalDataset));
var strAsObject = expandAssocArr(JSON.parse(objAsString));
There is relevant info on a configuration of CSRF with respect to API controllers on api.rubyonrails.org:
?
It's important to remember that XML or JSON requests are also affected and if you're building an API you should change forgery protection method in
ApplicationController
(by default::exception
):class ApplicationController < ActionController::Base protect_from_forgery unless: -> { request.format.json? } end
We may want to disable CSRF protection for APIs since they are typically designed to be state-less. That is, the request API client will handle the session for you instead of Rails.

I ran through similar problem and found that I was trying to get the offset of footer but I was loading my script inside a div before the footer. It was something like this:
<div> I have some contents </div>
<script>
$('footer').offset().top;
</script>
<footer>This is footer</footer>
So, the problem was, I was calling the footer element before the footer was loaded.
I pushed down my script below footer and it worked fine!
In UTF-8:
1 byte: 0 - 7F (ASCII)
2 bytes: 80 - 7FF (all European plus some Middle Eastern)
3 bytes: 800 - FFFF (multilingual plane incl. the top 1792 and private-use)
4 bytes: 10000 - 10FFFF
In UTF-16:
2 bytes: 0 - D7FF (multilingual plane except the top 1792 and private-use )
4 bytes: D800 - 10FFFF
In UTF-32:
4 bytes: 0 - 10FFFF
10FFFF is the last unicode codepoint by definition, and it's defined that way because it's UTF-16's technical limit.
It is also the largest codepoint UTF-8 can encode in 4 byte, but the idea behind UTF-8's encoding also works for 5 and 6 byte encodings to cover codepoints until 7FFFFFFF, ie. half of what UTF-32 can.

Check the parse_string
function http://php.net/manual/en/function.parse-str.php
It will return all the variables from a query string, including arrays.
Example from php.net:
<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str);
echo $first; // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz
parse_str($str, $output);
echo $output['first']; // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz
?>
Descendants will do exactly what you need, but be sure that you have included a namespace name together with element's name. If you omit it, you will probably get an empty list.
In some cases this is the best way because your code may have change something and j=i+1 won't check that.
for (int i = 0; i < list.size(); i++){
for (int j = 0; j < list.size(); j++) {
if(i == j) {
//to do code here
continue;
}
}
}

The semantics of Having
To better understand having, you need to see it from a theoretical point of view.
A group by is a query that takes a table and summarizes it into another table. You summarize the original table by grouping the original table into subsets (based upon the attributes that you specify in the group by). Each of these groups will yield one tuple.
The Having is simply equivalent to a WHERE clause after the group by has executed and before the select part of the query is computed.
Lets say your query is:
select a, b, count(*)
from Table
where c > 100
group by a, b
having count(*) > 10;
The evaluation of this query can be seen as the following steps:
You can extend this to any complex query there Table can be any complex query that return a table (a cross product, a join, a UNION, etc).
In fact, having is syntactic sugar and does not extend the power of SQL. Any given query:
SELECT list
FROM table
GROUP BY attrList
HAVING condition;
can be rewritten as:
SELECT list from (
SELECT listatt
FROM table
GROUP BY attrList) as Name
WHERE condition;
The listatt is a list that includes the GROUP BY attributes and the expressions used in list and condition. It might be necessary to name some expressions in this list (with AS). For instance, the example query above can be rewritten as:
select a, b, count
from (select a, b, count(*) as count
from Table
where c > 100
group by a, b) as someName
where count > 10;
The solution you need
Your solution seems to be correct:
SELECT s.sid, s.name
FROM Supplier s, Supplies su, Project pr
WHERE s.sid = su.sid AND su.jid = pr.jid
GROUP BY s.sid, s.name
HAVING COUNT (DISTINCT pr.jid) >= 2
You join the three tables, then using sid as a grouping attribute (sname is functionally dependent on it, so it does not have an impact on the number of groups, but you must include it, otherwise it cannot be part of the select part of the statement). Then you are removing those that do not satisfy your condition: the satisfy pr.jid is >= 2
, which is that you wanted originally.
Best solution to your problem
I personally prefer a simpler cleaner solution:
SELECT sid, sname from
(SELECT sid from supplies
GROUP BY sid, pid
HAVING count(DISTINCT jid) >= 2
) AS T1
NATURAL JOIN
Supliers;
It will also be faster to execute, because the join is only done when needed, not all the times.

The error message means that you need to invoke volteado
and siprimo
on an instance of the Program
class. E.g.:
...
Program p = new Program();
long av = p.volteado(a); // av is "a" but swapped
if (p.siprimo(a) == false && p.siprimo(av) == false)
...
They cannot be invoked directly from the Main
method because Main
is static while volteado
and siprimo
are not.
The easiest way to fix this is to make the volteado
and siprimo
methods static:
private static bool siprimo(long a)
{
...
}
private static bool volteado(long a)
{
...
}
Semicolon should be at the end of the class definition rather than after the name:

The most versatile and most cross-browser solution is to avoid use of the "base" tag, and instead use the target attribute of the "a" tags:
<a target="_parent" href="http://www.stackoverflow.com">Stack Overflow</a>
The <base>
tag is less versatile and browsers are inconsistent in their requirements for its placement within the document, requiring more cross-browser testing. Depending on your project and situation, it can be difficult or even totally unfeasible to achieve the ideal cross-browser placement of the <base>
tag.
Doing this with the target="_parent"
attribute of the <a>
tag is not only more browser-friendly, but also allows you to distinguish between those links you want to open in the iframe, and those you want to open in the parent.
Assuming you're referring to this plugin, your code should be:
// To Store
$(function() {
$.session.set("myVar", "value");
});
// To Read
$(function() {
alert($.session.get("myVar"));
});
Before using a plugin, remember to read its documentation in order to learn how to use it. In this case, an usage example can be found in the README.markdown
file, which is displayed on the project page.
If you are certain that you have a JDK installed (and not a JRE), you can specify the location of the JDK on the commandline when starting the installer (as mentioned in the error message you get).

Here's a chunk of code that will write values to a log file. If the file doesn't exist, it creates it, otherwise it just appends to the existing file. You need to add "using System.IO;" at the top of your code, if it's not already there.
string strLogText = "Some details you want to log.";
// Create a writer and open the file:
StreamWriter log;
if (!File.Exists("logfile.txt"))
{
log = new StreamWriter("logfile.txt");
}
else
{
log = File.AppendText("logfile.txt");
}
// Write to the file:
log.WriteLine(DateTime.Now);
log.WriteLine(strLogText);
log.WriteLine();
// Close the stream:
log.Close();
gdb -ex=r --args myprogram arg1 arg2
-ex=r
is short for -ex=run
and tells gdb to run your program immediately, rather than wait for you to type "run" at the prompt. Then --args
says that everything that follows is the command and arguments, just as you'd normally type them at the commandline prompt.
You can search the app online in the Google Play Store. When found, check the url, for example, https://play.google.com/store/apps/details?id=lutey.FTPServer&hl=en
The id parameter corresponds to the package name of the application. In the case of the url in the example, the package name is lutey.FTPServer.
For bootstrap 4 version this code working;

As almost noted in comments to @BoltClock's answer, in modern browsers, you can actually add some html markup to pseudo-elements using the (url()
) in combination with svg's <foreignObject>
element.
You can either specify an URL pointing to an actual svg file, or create it with a dataURI version (data:image/svg+xml; charset=utf8, + encodeURIComponent(yourSvgMarkup)
)
But note that it is mostly a hack and that there are a lot of limitations :
document.styleSheets
. for this part, DOMParser
and XMLSerializer
may help.<img>
tags, this won't work in pseudo-elements (at least as of today, I don't know if it is specified anywhere that it shouldn't, so it may be a not-yet implemented feature).Now, a small demo of some html markup in a pseudo element :

You can use Apache commons-lang
StringUtils.isEmpty(String str)
- Checks if a String is empty ("") or null.
or
StringUtils.isBlank(String str)
- Checks if a String is whitespace, empty ("") or null.
the latter considers a String which consists of spaces or special characters eg " " empty too. See java.lang.Character.isWhitespace API
As an aside, it is always a good practice (and possibly a solution for this type of issue) to delete a large number of rows by using batches:
WHILE EXISTS (SELECT 1
FROM YourTable
WHERE <yourCondition>)
DELETE TOP(10000) FROM YourTable
WHERE <yourCondition>
Sort by picture and then by activity:
SELECT some_cols
FROM `prefix_users`
WHERE (some conditions)
ORDER BY pic_set, last_activity DESC;
If anyone is looking for an updated solution, Fernando's answer is pretty much perfect. Except that ComponentMetadata
has been deprecated. Using Component
instead worked for me.
The full Custom Decorator CustomDecorator.ts
file looks like this:
import 'zone.js';
import 'reflect-metadata';
import { Component } from '@angular/core';
import { isPresent } from "@angular/platform-browser/src/facade/lang";
export function CustomComponent(annotation: any) {
return function (target: Function) {
var parentTarget = Object.getPrototypeOf(target.prototype).constructor;
var parentAnnotations = Reflect.getMetadata('annotations', parentTarget);
var parentAnnotation = parentAnnotations[0];
Object.keys(parentAnnotation).forEach(key => {
if (isPresent(parentAnnotation[key])) {
// verify is annotation typeof function
if(typeof annotation[key] === 'function'){
annotation[key] = annotation[key].call(this, parentAnnotation[key]);
}else if(
// force override in annotation base
!isPresent(annotation[key])
){
annotation[key] = parentAnnotation[key];
}
}
});
var metadata = new Component(annotation);
Reflect.defineMetadata('annotations', [ metadata ], target);
}
}
Then import it in to your new component sub-component.component.ts
file and use @CustomComponent
instead of @Component
like this:
import { CustomComponent } from './CustomDecorator';
import { AbstractComponent } from 'path/to/file';
...
@CustomComponent({
selector: 'subcomponent'
})
export class SubComponent extends AbstractComponent {
constructor() {
super();
}
// Add new logic here!
}
You can use git log to display the diffs while searching:
git log -p -- path/to/file
The simple answer is yes - new() creates an object on the heap (with the unfortunate side effect that you have to manage its lifetime (by explicitly calling delete on it), whereas the second form creates an object in the stack in the current scope and that object will be destroyed when it goes out of scope.
You have to match the settings for PHP-FPM and Nginx to communicate over sockets or TCP.
So go to /etc/php5/fpm/pool.d/www.conf
and look for this line:
listen = /var/run/php5-fpm.sock
Then go to /etc/nginx/nginx.conf
Look for this:
upstream php {
server unix:/var/run/php5-fpm.socket;
}
Match those values and you should be all set.
After some trial and tribulation, I was able to find all .msi files in a given directory and install them.
foreach($_msiFiles in
($_msiFiles = Get-ChildItem $_Source -Recurse | Where{$_.Extension -eq ".msi"} |
Where-Object {!($_.psiscontainter)} | Select-Object -ExpandProperty FullName))
{
msiexec /i $_msiFiles /passive
}
spam = 'have a nice day'
var = 'd'
def count(spam, var):
found = 0
for key in spam:
if key == var:
found += 1
return found
count(spam, var)
print 'count %s is: %s ' %(var, count(spam, var))
data=np.genfromtxt(csv_file, delimiter=',', dtype='unicode')
It works fine for me.
A cleaner approach would be to create a Person
object that contains contactName
, contactPhone
, etc. Then, use an ArrayList
rather then an array to add the new objects. Create a loop that accepts all the fields for each `Person:
while (!done) {
Person person = new Person();
String name = input.nextLine();
person.setContactName(name);
...
myPersonList.add(person);
}
Using the list will remove the need for array bounds checking.
In our case, the wrong version of the Sysdeo Tomcat plugin for Eclipse 3.5 was being used. The fix:
tomcatPluginV33
instead of tomcatPluginV321
(extract to C:\eclipse\dropins
)DevloaderTomcat7.jar
was placed in the tomcat lib
folderThis problem may have been unique to our environment; but, I'll record it here anyway, for posterity's sake.
Great reference. Thanks! An addition to it:
If you happen to have a library project included which has declared custom attributes for a custom view, you have to declare your project namespace, not the library one's. Eg:
Given that the library has the package "com.example.library.customview" and the working project has the package "com.example.customview", then:
Will not work (shows the error " error: No resource identifier found for attribute 'newAttr' in package 'com.example.library.customview'" ):
<com.library.CustomView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res/com.example.library.customview"
android:id="@+id/myView"
app:newAttr="value" />
Will work:
<com.library.CustomView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res/com.example.customview"
android:id="@+id/myView"
app:newAttr="value" />
You can do this:
add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010
and most of it will work (although MS support will tell you that doing this is not supported because it bypasses RBAC).
I've seen issues with some cmdlets (specifically enable/disable UMmailbox) not working with just the snapin loaded.
In Exchange 2010, they basically don't support using Powershell outside of the the implicit remoting environment of an actual EMS shell.
//Get Only number from string
$string = "123 Hello Zahid";
$res = preg_replace("/[^0-9]/", "", $string);
echo $res."<br>";
//Result 123
Well, in your code you are trying to return a String
(in C which is nothing but a null-terminated array of characters), but the return type of your function is char
which is causing all the trouble for you. Instead you should write it this way:
const char* myFunction()
{
return "My String";
}
And it's always good to qualify your type with const
while assigning literals in C to pointers as literals in C aren't modifiable.
I was searching after a toggling method that does the same, except for an inital value of null
or undefined
, where it should become false
.
Here it is:
booly = !(booly != false)
Just use notepad ++ with encoding UTF-8 without BOM.
Using a property for the version generates the following warning:
[WARNING]

[WARNING]
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING]
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.
[WARNING]
If your problem is that you have to change the version in multiple places because you are switching versions, then the correct thing to do is to use the Maven Release Plugin that will do this for you automatically.
If you want to use the numbers
method, you need an int array to store the returned value.
public static void main(String[] args){
int[] someNumbers = numbers();
//do whatever you want with them...
System.out.println(Arrays.toString(someNumbers));
}
You'd have to store couplets of object/value pairs in some internal state:
HashMap = function(){
this._dict = [];
}
HashMap.prototype._get = function(key){
for(var i=0, couplet; couplet = this._dict[i]; i++){
if(couplet[0] === key){
return couplet;
}
}
}
HashMap.prototype.put = function(key, value){
var couplet = this._get(key);
if(couplet){
couplet[1] = value;
}else{
this._dict.push([key, value]);
}
return this; // for chaining
}
HashMap.prototype.get = function(key){
var couplet = this._get(key);
if(couplet){
return couplet[1];
}
}
And use it as such:
var color = {}; // Unique object instance
var shape = {}; // Unique object instance
var map = new HashMap();
map.put(color, "blue");
map.put(shape, "round");
console.log("Item is", map.get(color), "and", map.get(shape));
Of course, this implementation is also somewhere along the lines of O(n). Eugene's examples are the only way to get a hash that works with any sort of speed you'd expect from a real hash.
Another approach, along the lines of Eugene's answer is to somehow attach a unique ID to all objects. One of my favorite approaches is to take one of the built-in methods inherited from the Object superclass, replace it with a custom function passthrough and attach properties to that function object. If you were to rewrite my HashMap method to do this, it would look like:
HashMap = function(){
this._dict = {};
}
HashMap.prototype._shared = {id: 1};
HashMap.prototype.put = function put(key, value){
if(typeof key == "object"){
if(!key.hasOwnProperty._id){
key.hasOwnProperty = function(key){
return Object.prototype.hasOwnProperty.call(this, key);
}
key.hasOwnProperty._id = this._shared.id++;
}
this._dict[key.hasOwnProperty._id] = value;
}else{
this._dict[key] = value;
}
return this; // for chaining
}
HashMap.prototype.get = function get(key){
if(typeof key == "object"){
return this._dict[key.hasOwnProperty._id];
}
return this._dict[key];
}
This version appears to be only slightly faster, but in theory it will be significantly faster for large data sets.

USE urllib.request.urlretrieve() AND PIL.Image.open() TO DOWNLOAD AND READ IMAGE DATA :
import requests
import urllib.request
import PIL
urllib.request.urlretrieve("https://i.imgur.com/ExdKOOz.png", "sample.png")
img = PIL.Image.open("sample.png")
img.show()
or Call requests.get(url) with url as the address of the object file to download via a GET request. Call io.BytesIO(obj) with obj as the content of the response to load the raw data as a bytes object. To load the image data, call PIL.Image.open(bytes_obj) with bytes_obj as the bytes object:
import io
response = requests.get("https://i.imgur.com/ExdKOOz.png")
image_bytes = io.BytesIO(response.content)
img = PIL.Image.open(image_bytes)
img.show()
You can use http_response_code()
to set HTTP response code.
If you pass no parameters then http_response_code will get the current status code. If you pass a parameter it will set the response code.
http_response_code(201); // Set response status code to 201
For Laravel(Reference from: https://stackoverflow.com/a/14717895/2025923):
return Response::json([
'hello' => $value
], 201); // Status code here
No, you can just write the function as:
$(document).ready(function() {
MyBlah("hello");
});
function MyBlah(blah) {
alert(blah);
}
This calls the function MyBlah
on content ready.
Because C will promote floats to doubles for functions that take variable arguments. Pointers aren't promoted to anything, so you should be using %lf
, %lg
or %le
(or %la
in C99) to read in doubles.
This problem happens when you install the JDK by _uncompressing_
it instead of _executing_
it.
By example:
unzip jdk-6u45-linux-x64.bin (wrong)
sh ./jdk-6u45-linux-x64.bin (right)
In the first scenario, the runtime libraries, as rt.jar, don't get automatically uncompresessed (thus, you can find the rt.pack files, etc. instead of the .jar ones).
I had same problem and waste my 4-5 hours for solution. My problem solved with;

Other way is using concat() function:

Q: The programming model is event driven, especially the way it handles I/O.
Correct. It uses call-backs, so any request to access the file system would cause a request to be sent to the file system and then Node.js would start processing its next request. It would only worry about the I/O request once it gets a response back from the file system, at which time it will run the callback code. However, it is possible to make synchronous I/O requests (that is, blocking requests). It is up to the developer to choose between asynchronous (callbacks) or synchronous (waiting).
Q: It uses JavaScript and the parser is V8.
Yes
Q: It can be easily used to create concurrent server applications.
Yes, although you'd need to hand-code quite a lot of JavaScript. It might be better to look at a framework, such as http://www.easynodejs.com/ - which comes with full online documentation and a sample application.
[Update]
More recently, there is Amazon AWS ECR (Elastic Container Registry), which provides a Docker image registry to which you can control access by means of the AWS IAM access management service. ECR can also run a CVE (vulnerabilities) check on your image when you push it.
Once you create your ECR, and obtain the "URL" you can push and pull as required, subject to the permissions you create: hence making it private or public as you wish.
Pricing is by amount of data stored, and data transfer costs.
[Original answer]
If you do not want to use the Docker Hub itself, you can host your own Docker repository under Artifactory by JFrog:
https://www.jfrog.com/confluence/display/RTF/Docker+Repositories
which will then run on your own server(s).
Other hosting suppliers are available, eg CoreOS:
http://www.theregister.co.uk/2014/10/30/coreos_enterprise_registry/
which bought quay.io
Most of the answers here are either 'UnSafe" or not LittleEndian safe. BitConverter is not LittleEndian safe. So building on an example in here (see the post by PZahra) I made a LittleEndian safe version simply by reading the byte array in reverse when BitConverter.IsLittleEndian == true
void Main(){
Console.WriteLine(BitConverter.IsLittleEndian);
byte[] bytes = BitConverter.GetBytes(0xdcbaabcdfffe1608);
//Console.WriteLine(bytes);
string hexStr = ByteArrayToHex(bytes);
Console.WriteLine(hexStr);
}
public static string ByteArrayToHex(byte[] data)
{
char[] c = new char[data.Length * 2];
byte b;
if(BitConverter.IsLittleEndian)
{
//read the byte array in reverse
for (int y = data.Length -1, x = 0; y >= 0; --y, ++x)
{
b = ((byte)(data[y] >> 4));
c[x] = (char)(b > 9 ? b + 0x37 : b + 0x30);
b = ((byte)(data[y] & 0xF));
c[++x] = (char)(b > 9 ? b + 0x37 : b + 0x30);
}
}
else
{
for (int y = 0, x = 0; y < data.Length; ++y, ++x)
{
b = ((byte)(data[y] >> 4));
c[x] = (char)(b > 9 ? b + 0x37 : b + 0x30);
b = ((byte)(data[y] & 0xF));
c[++x] = (char)(b > 9 ? b + 0x37 : b + 0x30);
}
}
return String.Concat("0x",new string(c));
}
It returns this:
True
0xDCBAABCDFFFE1608
which is the exact hex that went into the byte array.
You can't replace a letter in a string. Convert the string to a list, replace the letter, and convert it back to a string.
>>> s = list("Hello world")
>>> s
['H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd']
>>> s[int(len(s) / 2)] = '-'
>>> s
['H', 'e', 'l', 'l', 'o', '-', 'W', 'o', 'r', 'l', 'd']
>>> "".join(s)
'Hello-World'
Use Javascript's setTimeout:
<body onload="setTimeout(function(){window.location = 'form2.html';}, 5000)">
why don't you store your values in HTML5 storage objects such as sessionStorage
or localStorage
, visit HTML5 Storage Doc to get more details. Using this you can store intermediate values temporarily/permanently locally and then access your values later.
To store values for a session:
sessionStorage.getItem('label')
sessionStorage.setItem('label', 'value')
or more permanently:
localStorage.getItem('label')
localStorage.setItem('label', 'value')
So you can store (temporarily) form data between multiple pages using HTML5 storage objects which you can even retain after reload..
Here's another way:
>>> L = range (11)
>>> map(lambda x: x if x%2 else None, L)
[None, 1, None, 3, None, 5, None, 7, None, 9, None]
You can use list slicing to archive your goal:
n = 5
mylist = [1,2,3,4,5,6,7,8,9]
newlist = mylist[n:]
print newlist
Outputs:
[6, 7, 8, 9]
Or del
if you only want to use one list:
n = 5
mylist = [1,2,3,4,5,6,7,8,9]
del mylist[:n]
print mylist
Outputs:
[6, 7, 8, 9]
I'd suggest doing something similar to:
function show_sub(cat) {
if (!cat) {
return false;
}
else if (document.getElementById(cat)) {
var parent = document.getElementById(cat),
sub = parent.getElementsByClassName('sub');
if (sub[0].style.display == 'inline'){
sub[0].style.display = 'none';
}
else {
sub[0].style.display = 'inline';
}
}
}
document.getElementById('cat').onclick = function(){
show_sub(this.id);
};????
Though the above relies on the use of a class
rather than a name
attribute equal to sub
.
As to why your original version "didn't work" (not, I must add, a particularly useful description of the problem), all I can suggest is that, in Chromium, the JavaScript console reported that:
Uncaught TypeError: Object # has no method 'getElementsByName'.
One approach to working around the older-IE family's limitations is to use a custom function to emulate getElementsByClassName()
, albeit crudely:
function eBCN(elem,classN){
if (!elem || !classN){
return false;
}
else {
var children = elem.childNodes;
for (var i=0,len=children.length;i<len;i++){
if (children[i].nodeType == 1
&&
children[i].className == classN){
var sub = children[i];
}
}
return sub;
}
}
function show_sub(cat) {
if (!cat) {

You are trying to use the wrong interface type. The type Function is not appropriate in this case because it receives a parameter and has a return value. Instead you should use Consumer (formerly known as Block)
The Function type is declared as
interface Function<T,R> {
R apply(T t);
}
However, the Consumer type is compatible with that you are looking for:
interface Consumer<T> {
void accept(T t);
}
As such, Consumer is compatible with methods that receive a T and return nothing (void). And this is what you want.
For instance, if I wanted to display all element in a list I could simply create a consumer for that with a lambda expression:
List<String> allJedi = asList("Luke","Obiwan","Quigon");
allJedi.forEach( jedi -> System.out.println(jedi) );
You can see above that in this case, the lambda expression receives a parameter and has no return value.
Now, if I wanted to use a method reference instead of a lambda expression to create a consume of this type, then I need a method that receives a String and returns void, right?.
I could use different types of method references, but in this case let's take advantage of an object method reference by using the println
method in the System.out
object, like this:
Consumer<String> block = System.out::println
Or I could simply do
allJedi.forEach(System.out::println);
The println
method is appropriate because it receives a value and has a return type void, just like the accept
method in Consumer.
So, in your code, you need to change your method signature to somewhat like:
public static void myForEach(List<Integer> list, Consumer<Integer> myBlock) {
list.forEach(myBlock);
}
And then you should be able to create a consumer, using a static method reference, in your case by doing:
myForEach(theList, Test::displayInt);
Ultimately, you could even get rid of your myForEach
method altogether and simply do:
theList.forEach(Test::displayInt);
About Functions as First Class Citizens
All been said, the truth is that Java 8 will not have functions as first-class citizens since a structural function type will not be added to the language. Java will simply offer an alternative way to create implementations of functional interfaces out of lambda expressions and method references. Ultimately lambda expressions and method references will be bound to object references, therefore all we have is objects as first-class citizens. The important thing is the functionality is there since we can pass objects as parameters, bound them to variable references and return them as values from other methods, then they pretty much serve a similar purpose.
Two ways of doing it.
<asp:Calendar ID="planning" runat="server" SelectedDate="<%# DateTime.Now %>"></asp:Calendar>
protected void Page_Load(object sender, EventArgs e)
{
BindCalendar();
}
private void BindCalendar()
{
planning.SelectedDate = DateTime.Today;
}
Altough, I strongly recommend to do it from a BindMyStuff way. Single entry point easier to debug. But since you seems to know your game, you're all set.

You can just go to the DEBUG menu ? Main Properties ? Configuration properties ? Debugging and then you will see the box for the command line arguments.
Actually, you can set the same input arguments for all the different configurations and not only for debugging.
From the pull down menu of configuration select: All Configurations and insert the input arguments (each argument separated by space).
Now, you can execute your program in different modes without having to change the input arguments every time.

The length of the url can't be changed in PHP. The linked question is about the URL size limit, you will find what you want.
BTW, if you want some semantics such as only put if this key is not exist. you can use concurrentHashMap
with putIfAbsent()
function.
Check this out:
https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ConcurrentHashMap.html#put(K,%20V)
concurrentHashMap
is thread safe with high performance since it uses "lock striping" mechanism to improve the throughput.

The deduplication (to select the max T1) and the aggregation need to be done as distinct steps. I've used a CTE since I think this makes it clearer:
;WITH sumCTE
AS
(
SELECT Rel.t2ID, SUM(Price) price
FROM @t1 AS T1
JOIN @relation AS Rel
ON Rel.t1ID=T1.ID
GROUP
BY Rel.t2ID
)
,maxCTE
AS
(
SELECT Rel.t2ID, Rel.t1ID,
ROW_NUMBER()OVER(Partition By Rel.t2ID Order By Price DESC)As PriceList
FROM @t1 AS T1
JOIN @relation AS Rel
ON Rel.t1ID=T1.ID
)
SELECT T2.ID AS T2ID
,T2.Name as T2Name
,T2.Orders
,T1.ID AS T1ID
,T1.Name As T1Name
,sumT1.Price
FROM @t2 AS T2
JOIN sumCTE AS sumT1
ON sumT1.t2ID = t2.ID
JOIN maxCTE AS maxT1
ON maxT1.t2ID = t2.ID
JOIN @t1 AS T1
ON T1.ID = maxT1.t1ID
WHERE maxT1.PriceList = 1
You almost got it. You are hiding the rows within the active sheet. which is okay. But a better way would be add where it is.
Rows("52:55").EntireRow.Hidden = False
becomes
activesheet.Rows("52:55").EntireRow.Hidden = False
i've had weird things happen without it. As for making it automatic. You need to use the worksheet_change event within the sheet's macro in the VBA editor (not modules, double click the sheet1 to the far left of the editor.) Within that sheet, use the drop down menu just above the editor itself (there should be 2 listboxes). The listbox to the left will have the events you are looking for. After that just throw in the macro. It should look like the below code,
Private Sub Worksheet_Change(ByVal Target As Range)
test1
end Sub
That's it. Anytime you change something, it will run the macro test1.

To solve this issue you need below three steps:
Set page encoding to UTF-8 like below:
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ page contentType="text/html;charset=UTF-8" %>
Set filter in web.xml file as below:
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Set resource encoding to UTF-8, in case if you are writing any UTF-8 characters in Java code or JSP directly.
There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)
You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.
UNAME := $(shell uname -m)
all:
$(info Checking if custom header is needed)
ifeq ($(UNAME), x86_64)
... do some things to build unistd_32.h
endif
@make -C $(KDIR) M=$(PWD) modules
So you want unistd_32.h built (maybe) before you invoke the second make
, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:
ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif
all:
@make -C $(KDIR) M=$(PWD) modules
unistd_32.h:
... do some things to build unistd_32.h
Now for building unistd_32.h
:
F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
$(info Copying custom header)
$(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else
F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
ifeq ($(F2_EXISTS), 1)
$(info Copying custom header)
$(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
else
$(error asm/unistd_32.h and asm-386/unistd.h does not exist)
endif
endif
You are trying to build unistd.h
from unistd_32.h
; the only trick is that unistd_32.h
could be in either of two places. The simplest way to clean this up is to use a vpath
directive:
vpath unistd.h /usr/include/asm /usr/include/asm-i386
unistd_32.h: unistd.h
sed -e 's/__NR_/__NR32_/g' $< > $@
For some devices, if the default language is set different (an indian can set English (US)) then
context.getResources().getConfiguration().locale.getDisplayCountry();
will give wrong value .So this method is non reliable
Also, getNetworkCountryIso() method of TelephonyManager will not work on devices which don't have SIM card (WIFI tablets).
If a device doesn't have SIM then we can use Time Zone to get the country. For countries like India, this method will work
sample code used to check the country is India or not (Time zone id : asia/calcutta)
private void checkCountry() {
TelephonyManager telMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (telMgr == null)
return;
int simState = telMgr.getSimState();
switch (simState) {
//if sim is not available then country is find out using timezone id
case TelephonyManager.SIM_STATE_ABSENT:
TimeZone tz = TimeZone.getDefault();
String timeZoneId = tz.getID();
if (timeZoneId.equalsIgnoreCase(Constants.INDIA_TIME_ZONE_ID)) {
//do something
} else {
//do something
}
break;
//if sim is available then telephony manager network country info is used
case TelephonyManager.SIM_STATE_READY:
TelephonyManager tm = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
if (tm != null) {
String countryCodeValue = tm.getNetworkCountryIso();
//check if the network country code is "in"
if (countryCodeValue.equalsIgnoreCase(Constants.NETWORK_INDIA_CODE)) {
//do something
}
else {
//do something
}
}
break;
}
}
You can actually "request" MySQL for a list of all locations where it searches for my.cnf (or my.ini on Windows). It is not an SQL query though. Rather, execute:
$ mysqladmin --help
or, prior 5.7:
$ mysqld --help --verbose
In the very first lines you will find a message with a list of all my.cnf locations it looks for. On my machine it is:
Default options are read from the following files in the given order:
/etc/my.cnf
/etc/mysql/my.cnf
/usr/etc/my.cnf
~/.my.cnf
Or, on Windows:
Default options are read from the following files in the given order:
C:\Windows\my.ini
C:\Windows\my.cnf
C:\my.ini
C:\my.cnf
C:\Program Files\MySQL\MySQL Server 5.5\my.ini
C:\Program Files\MySQL\MySQL Server 5.5\my.cnf
Note however, that it might be the case that there is no my.cnf file at any of these locations. So, you can create the file on your own - use one of the sample config files provided with MySQL distribution (on Linux - see /usr/share/mysql/*.cnf
files and use whichever is appropriate for you - copy it to /etc/my.cnf
and then modify as needed).
Also, note that there is also a command line option --defaults-file
which may define custom path to my.cnf or my.ini file. For example, this is the case for MySQL 5.5 on Windows - it points to a my.ini file in the data directory, which is not normally listed with mysqld --help --verbose
. On Windows - see service properties to find out if this is the case for you.
Finally, check the https://dev.mysql.com/doc/refman/8.0/en/option-files.html - it is described there in more details.
I had a hard time finding where it is so here the image depicting it in 2019.
We'll check a Collection object is empty, null or not. these all methods which are given below, are present in org.apache.commons.collections4.CollectionUtils package.

Check on Map type of Objects.
MapUtils.isEmpty(mapObject);
MapUtils.isNotEmpty(mapObject);
The return type of all methods is boolean.
your elemId
as its name suggests, is an Id
attribute, these are all you can do to check if it exists:
Vanilla JavaScript: in case you have more advanced selectors:
//you can use it for more advanced selectors
if(document.querySelectorAll("#elemId").length){}
if(document.querySelector("#elemId")){}
//you can use it if your selector has only an Id attribute
if(document.getElementById("elemId")){}
jQuery:
if(jQuery("#elemId").length){}

Usually you can just upload your plugin to the wp-content\plugins
directory. If you don't have access to this directory via SFTP I'm afraid you may be stuck.
In addition to the previous answers, here is a way to calculate the distance inside a SELECT:
CREATE FUNCTION Get_Distance
(
@La1 float , @Lo1 float , @La2 float, @Lo2 float
)
RETURNS TABLE
AS
RETURN
-- Distance in Meters
SELECT GEOGRAPHY::Point(@La1, @Lo1, 4326).STDistance(GEOGRAPHY::Point(@La2, @Lo2, 4326))
AS Distance
GO
Usage:
select Distance
from Place P1,
Place P2,
outer apply dbo.Get_Distance(P1.latitude, P1.longitude, P2.latitude, P2.longitude)
Scalar functions also work but they are very inefficient when computing large amount of data.
I hope this might help someone.
An index is just a data structure that makes the searching faster for a specific column in a database. This structure is usually a b-tree or a hash table but it can be any other logic structure.
You can use this:
myDropDown.Items.Remove(myDropDown.Items.FindByValue("TextToFind"));
If everything works as it should it shouldn't, BUT we all know everything doesn't work the way it should especially when it comes to the query optimizer, query plan caching and statistics.
First I would suggest rebuilding index and statistics, then clearing the query plan cache just to make sure that's not screwing things up. However I've experienced problems even when that's done.
I've experienced some cases where a left join has been faster than a inner join.
The underlying reason is this: If you have two tables and you join on a column with an index (on both tables). The inner join will produce the same result no matter if you loop over the entries in the index on table one and match with index on table two as if you would do the reverse: Loop over entries in the index on table two and match with index in table one. The problem is when you have misleading statistics, the query optimizer will use the statistics of the index to find the table with least matching entries (based on your other criteria). If you have two tables with 1 million in each, in table one you have 10 rows matching and in table two you have 100000 rows matching. The best way would be to do an index scan on table one and matching 10 times in table two. The reverse would be an index scan that loops over 100000 rows and tries to match 100000 times and only 10 succeed. So if the statistics isn't correct the optimizer might choose the wrong table and index to loop over.
If the optimizer chooses to optimize the left join in the order it is written it will perform better than the inner join.
BUT, the optimizer may also optimize a left join sub-optimally as a left semi join. To make it choose the one you want you can use the force order hint.
It is an old question, but I just ran into it.
Type.GetMethod(string name)
will throw an AmbiguousMatchException if there is more than one method with that name, so we better handle that case
public static bool HasMethod(this object objectToCheck, string methodName)

var type = objectToCheck.GetType();
return type.GetMethod(methodName) != null;
}
catch(AmbiguousMatchException)
{
// ambiguous means there is more than one result,
// which means: a method with that name does exist
return true;
}
}

I figured out that the plt.pause(0.001)
command is the only thing needed and nothing else.
plt.show() and plt.draw() are unnecessary and / or blocking in one way or the other. So here is a code that draws and updates a figure and keeps going. Essentially plt.pause(0.001) seems to be the closest equivalent to matlab's drawnow.
Unfortunately those plots will not be interactive (they freeze), except you insert an input() command, but then the code will stop.
The documentation of the plt.pause(interval) command states:
If there is an active figure, it will be updated and displayed before the pause...... This can be used for crude animation.
and this is pretty much exactly what we want. Try this code:
import numpy as np
from matplotlib import pyplot as plt
x = np.arange(0, 51) # x coordinates
for z in range(10, 50):
y = np.power(x, z/10) # y coordinates of plot for animation
plt.cla() # delete previous plot
plt.axis([-50, 50, 0, 10000]) # set axis limits, to avoid rescaling
plt.plot(x, y) # generate new plot
plt.pause(0.1) # pause 0.1 sec, to force a plot redraw
You could store your JSON inside of an array and then insert the JSON data into the array with push
Check this out https://jsfiddle.net/cx2rk40e/2/
$(document).ready(function(){
// using jQuery just to load function but will work without library.
$( "button" ).on( "click", go );
// Array of JSON we will append too.
var jsonTest = [{
"colour": "blue",
"link": "http1"
}]
// Appends JSON to array with push. Then displays the data in alert.
function go() {
jsonTest.push({"colour":"red", "link":"http2"});
alert(JSON.stringify(jsonTest));
}
});
Result of JSON.stringify(jsonTest)
[{"colour":"blue","link":"http1"},{"colour":"red","link":"http2"}]
This answer maybe useful to users who wish to emulate a similar result.

This is the correct way to replace a portion of text inside a string (based upon the getBetween method by Oscar Jara):
public static string ReplaceTextBetween(string strSource, string strStart, string strEnd, string strReplace)
{
int Start, End, strSourceEnd;
if (strSource.Contains(strStart) && strSource.Contains(strEnd))
{
Start = strSource.IndexOf(strStart, 0) + strStart.Length;
End = strSource.IndexOf(strEnd, Start);
strSourceEnd = strSource.Length - 1;
string strToReplace = strSource.Substring(Start, End - Start);
string newString = string.Concat(strSource.Substring(0, Start), strReplace, strSource.Substring(Start + strToReplace.Length, strSourceEnd - Start));
return newString;
}
else
{
return string.Empty;
}
}
The string.Concat
concatenates 3 strings:
strSource.Substring(0, Start)
strReplace
strSource.Substring(Start + strToReplace.Length, strSourceEnd - Start)
Seems the most foolproof way to start with a UTC date is to create a new Date

Nonatomic
will not generate threadsafe routines thru @synthesize
accessors. atomic
will generate threadsafe accessors so atomic
variables are threadsafe (can be accessed from multiple threads without botching of data)
copy
is required when the object is mutable. Use this if you need the value of the object as it is at this moment, and you don't want that value to reflect any changes made by other owners of the object. You will need to release the object when you are finished with it because you are retaining the copy.
Assign
is somewhat the opposite to copy
. When calling the getter of an assign
property, it returns a reference to the actual data. Typically you use this attribute when you have a property of primitive type (float, int, BOOL...)
retain
is required when the attribute is a pointer to a reference counted object that was allocated on the heap. Allocation should look something like:
NSObject* obj = [[NSObject alloc] init]; // ref counted var
The setter generated by @synthesize
will add a reference count to the object when it is copied so the underlying object is not autodestroyed if the original copy goes out of scope.
You will need to release the object when you are finished with it. @property
s using retain
will increase the reference count and occupy memory in the autorelease pool.
strong
is a replacement for the retain attribute, as part of Objective-C Automated Reference Counting (ARC). In non-ARC code it's just a synonym for retain.
This is a good website to learn about strong
and weak
for iOS 5.
http://www.raywenderlich.com/5677/beginning-arc-in-ios-5-part-1
Weak
weak
is similar to strong
except that it won't increase the reference count by 1. It does not become an owner of that object but just holds a reference to it. If the object's reference count drops to 0, even though you may still be pointing to it here, it will be deallocated from memory.
The above link contain both Good information regarding Weak and Strong.
This is a late answer, due to a fairly recent development. Since the OP accepted the answer that relies on a non-portable GCC (and clang) extension typeof
- or __typeof__
for 'clean' ISO C - there's a better solution available as of gcc-4.9.
#define max(x,y) ( \
{ __auto_type __x = (x); __auto_type __y = (y); \
__x > __y ? __x : __y; })
The obvious benefit of this extension is that each macro argument is only expanded once, unlike the __typeof__
solution.
__auto_type
is a limited form of C++11's auto
. It cannot (or should not?) be used in C++ code, though there's no good reason not to use the superior type inference capabilities of auto
when using C++11.
That said, I assume there are no issues using this syntax when the macro is included in an extern "C" { ... }
scope; e.g., from a C header. AFAIK, this extension has not found its way info clang
I'm not sure if there's an absolute authoritative answer to this, but you may look upon it as a distinction of what happens when the request hits the webserver. The request may either be served by having the server return a file that's already been made (static content), or it can pass the request to an application that generates the respone sent back to the browser (dynamic content).
Both types will be called a website, but only the ones that have an application generate the contents will be called a web application.
How the application is written is of less concern. It may be ASP, PHP, Ruby, JavaScript or even C or C++.
You should specify column names as below. It's good practice and probably solve your problem
insert into abc.employees (col1,col2)
select col1,col2 from employees where employee_id=100;
EDIT:
As you said employees
has 112 columns (sic!) try to run below select to compare both tables' columns
select *
from ALL_TAB_COLUMNS ATC1
left join ALL_TAB_COLUMNS ATC2 on ATC1.COLUMN_NAME = ATC1.COLUMN_NAME
and ATC1.owner = UPPER('2nd owner')
where ATC1.owner = UPPER('abc')
and ATC2.COLUMN_NAME is null
AND ATC1.TABLE_NAME = 'employees'
and than you should upgrade your tables to have the same structure.
As explained in http://www.regular-expressions.info/anchors.html under the section "Strings Ending with a Line Break", \Z
will generally match before the end of the last newline in strings that end in a newline. If you want to only match the end of the string, you need to use \z
. The exception to this rule is Python.
In other words, to exclusively match an empty string, you need to use /\A\z/
.
try this:
split(das, cut(das$anim, 3))
if you want to split based on the value of wt
, then
library(Hmisc) # cut2
split(das, cut2(das$wt, g=3))
anyway, you can do that by combining cut
, cut2
and split
.
UPDATED
if you want a group index as an additional column, then
das$group <- cut(das$anim, 3)
if the column should be index like 1, 2, ..., then
das$group <- as.numeric(cut(das$anim, 3))
UPDATED AGAIN
try this:
> das$wt2 <- as.numeric(cut2(das$wt, g=3))
> das
anim wt wt2

Your problem seams to be located here:
SELECT @maxCode = CAST(MAX(CAST(SUBSTRING(Voucher_No,LEN(@startFrom)+1,LEN(Voucher_No)- LEN(@Prefix)) AS INT)) AS varchar(100)) FROM dbo.Journal_Entry;
SET @sCode=CAST(@maxCode AS INT)
As the error says, you're casting a string that contains a letter 'J' to an INT
which for obvious reasons is not possible.
Either fix SUBSTRING
or don't store the letter 'J' in the database and only prepend it when reading.
I once wrote something similar to Bartek's answer and javascript inspired:
def is_not_blank(s):
return bool(s and s.strip())
Test:
print is_not_blank("") # False
print is_not_blank(" ") # False
print is_not_blank("ok") # True
print is_not_blank(None) # False
The family of methods that does this are:
Returns the index within this string of the first (or last) occurrence of the specified substring [searching forward (or backward) starting at the specified index].
String text = "0123hello9012hello8901hello7890";
String word = "hello";
System.out.println(text.indexOf(word)); // prints "4"
System.out.println(text.lastIndexOf(word)); // prints "22"
// find all occurrences forward
for (int i = -1; (i = text.indexOf(word, i + 1)) != -1; i++) {
System.out.println(i);
} // prints "4", "13", "22"
// find all occurrences backward
for (int i = text.length(); (i = text.lastIndexOf(word, i - 1)) != -1; i++) {
System.out.println(i);
} // prints "22", "13", "4"
Try:
>>> t = ((1, 'a'),(2, 'b'))
>>> dict((y, x) for x, y in t)
{'a': 1, 'b': 2}
Use title
attribute.
It is a standard HTML attribute and is by default rendered in a tooltip by most desktop browsers.
I don't think that adding a port is good idea - specially when you got many servers with different builds. that just adds one more thing to remember to change. looking at doc's I think the last line of kaisers is quite good, so that:
if(!empty($_SERVER["HTTPS"]))
if($_SERVER["HTTPS"]!=="off")
return 1; //https
else
return 0; //http
else
return 0; //http
seems like perfectly enough.
File API File.getParent or File.getParentFile should return you Directory of file.
Your code should be like :
File file = new File("c:\\temp\\java\\testfile");
if(!file.exists()){
file = file.getParentFile();
}
You can additionally check your parent file is directory using File.isDirectory API
if(file.isDirectory()){
System.out.println("file is directory ");
}
I know this is an old post but just for reference. Here is how to append without the special case check for an empty list, although at the expense of more complex looking code.
void Append(List * l, Node * n)
{
Node ** next = &list->Head;
while (*next != NULL) next = &(*next)->Next;
*next = n;
n->Next = NULL;
}
I am using this base class connection with mysql:
"base.js"
var mysql = require("mysql");
var pool = mysql.createPool({
connectionLimit : 10,
host: Config.appSettings().database.host,
user: Config.appSettings().database.username,
password: Config.appSettings().database.password,
database: Config.appSettings().database.database
});
var DB = (function () {
function _query(query, params, callback) {
pool.getConnection(function (err, connection) {
if (err) {
connection.release();
callback(null, err);
throw err;
}
connection.query(query, params, function (err, rows) {
connection.release();
if (!err) {
callback(rows);
}
else {
callback(null, err);
}
});
connection.on('error', function (err) {
connection.release();
callback(null, err);
throw err;
});
});
};
return {
query: _query
};
})();
module.exports = DB;
Just use it like that:
var DB = require('../dal/base.js');
DB.query("select * from tasks", null, function (data, error) {
callback(data, error);
});
To give an alternative answer (Who needs 5 equal answers?):
list.Add(5);
// list contains at least one element now
list = new List<int>();
// list in "list" is empty now
Keep in mind that all other references to the old list have not been cleared (depending on the situation, this might be what you want). Also, in terms of performance, it is usually a bit slower.
Here's a small script implementing this feature (inspired by the Shea Frederick blog article that Kyle mentions):
What about?
public enum MyEnum {
FIRST,
SECOND,
THIRD;
public static Optional<MyEnum> fromString(String value){
try{
return Optional.of(MyEnum.valueOf(value));
}catch(Exception e){
return Optional.empty();
}
}
}
I know this is old question, but I wanted to do the same. Update a file in zip archive. And none of the above answers really helped me.
Here is what I did. Created temp directory abc
. Copied file.zip
to abc
and extracted the file in that directory. I edited the file I wanted to edit.
Then while being in abc
, ran the following command
user@host ~/temp/abc $ zip -u file.zip
updating: content/js/ (stored 0%)
updating: content/js/moduleConfig.js (deflated 69%)
-u
switch will look for changed/new files and will add to the zip archive.
They're examples provided by the Android team, if you've already loaded Samples, you can import Home screen replacement sample by following these steps.
File > New > Other >Android > Android Sample Project > Android x.x > Home > Finish
But if you do not have samples loaded, then download it using the below steps
Windows > Android SDK Manager > chooses "Sample for SDK" for SDK you need it > Install package > Accept License > Install
You can combine the find command and the ls command. Use the path (.) and selector (*) to narrow down the files you're after. Surround the find command in back quotes. The argument to -name is doublequote star doublequote in case you can't read it.
ls -lart `find . -type f -name "*" `
Here is my example:
<div class="form-group">
<label for="contactMethod">Contact method</label>
<select
name="contactMethod"
id="contactMethod"
class="form-control"
[(ngModel)]="contact.contactMethod">
<option *ngFor="let method of contactMethods" [value]="method.id">{{ method.label }}</option>
</select>
</div>
And in component you must get values from select:
contactMethods = [
{ id: 1, label: "Email" },
{ id: 2, label: "Phone" }
]
So, if you want select to have a default value selected (and proabbly you want that):
contact = {
firstName: "CFR",
comment: "No comment",
subscribe: true,
contactMethod: 2 // this id you'll send and get from backend
}
I was given access to a database, but not the table where my query was being stored in.
Inspired by @marc_s answer, I had a look at HeidiSQL which is a Windows program that can deal with MySQL, SQL Server, and PostgreSQL.
I found that it can also search a database for a string.
It will search each table and give you how many times it found the string per table!
so late, but with ES6 no need extends it still work for me.... :)
let getArray = <T>(items: T[]): T[] => {
return new Array<T>().concat(items)
}
let myNumArr = getArray<number>([100, 200, 300]);
let myStrArr = getArray<string>(["Hello", "World"]);
myNumArr.push(1)
console.log(myNumArr)
I had this problem too. I found setting the appearance to none helped.
.class {
appearance:none;
-moz-appearance:none;
-webkit-appearance:none;
background-color: red;
}
A simple increment should do the trick.
UPDATE mytable
SET logins = logins + 1
WHERE id = 12
If you would like to update a previously existing row, or insert it if it doesn't already exist, you can use the REPLACE
syntax or the INSERT...ON DUPLICATE KEY UPDATE
option (As Rob Van Dam demonstrated in his answer).
Or perhaps you're looking for something like INSERT...MAX(logins)+1
? Essentially you'd run a query much like the following - perhaps a bit more complex depending on your specific needs:
INSERT into mytable (logins)
SELECT max(logins) + 1
FROM mytable

First of all, I needed to instal as sudo
(admin) during NPM install
sudo npm install -g typescript
NPM installs the libraries under /usr/local/Cellar/node/<your latest version>/lib/node_modules/typescript
folder and symlinks at /usr/local/Cellar/node/<your latest version>/bin/tsc
hence I went ~/.zshrc ( .bashrc, if you use bash)and added /usr/local/Cellar/node/<your latest version>/bin
to the $PATH.
source ~/.zshrc
(.bashrc in your case)It looks like your Google Play registration payment didn’t process. This can happen sometimes if a card has expired, the credit card or credit card verification (CVC) number was entered incorrectly, or if your billing address doesn't match the address in your Google Payments account.
Here’s how you can find the details of your transaction:
Sign in to your Google Payments account at https://payments.google.com.
On the left menu, select the “Subscriptions and services” page.
On the “Other purchase activity” card, click View purchases.
Click the “Google Play” registration transaction to see your payment method.
You can click “Payment methods” on the left menu if you need to edit the addresses on your Google Payments account.
To add a new credit or debit card to your account, you can follow the instructions on the Google Payments Help Center (https://support.google.com/payments/answer/6220309).
Make sure the following line code should be there in AssemblyInfo.cs file.
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)]
and also check for this line in Application_start() method.
log4net.Config.XmlConfigurator.Configure();
From Official documents about Re-using Layouts
Although Android offers a variety of widgets to provide small and re-usable interactive elements, you might also need to re-use larger components that require a special layout. To efficiently re-use complete layouts, you can use the tag to embed another layout inside the current layout.
Here is my header.xml file which i can reuse using include tag
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:gravity="center"
android:text="@string/app_name"
android:textColor="#000000" />
</RelativeLayout>
No I use the tag in XML to add another layout from another XML file.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#f0f0f0" >
<include
android:id="@+id/header_VIEW"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
layout="@layout/header" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="#ffffff"
android:orientation="vertical"
android:padding="5dp" >
</LinearLayout>
You need to set the timeout to "None" when you open the serial port:
ser = serial.Serial(**bco_port**, timeout=None, baudrate=115000, xonxoff=False, rtscts=False, dsrdtr=False)
This is a blocking command, so you are waiting until you receive data that has newline (\n or \r\n) at the end: line = ser.readline()
Once you have the data, it will return ASAP.
Other way for get a list just local branch is:
git branch -a | grep -v 'remotes'
You can do it like that but storing a DataSet object in Session is not very efficient. If you have a web app with lots of users it will clog your server memory really fast.
If you really must do it like that I suggest removing it from the session as soon as you don't need the DataSet.
When you try to merge one commit with a commit that can be reached by following the first commit’s history, Git simplifies things by moving the pointer forward because there is no divergent work to merge together – this is called a “fast-forward.”
For more : http://git-scm.com/book/en/v2/Git-Branching-Basic-Branching-and-Merging
In another way,
If Master has not diverged, instead of creating a new commit, git will just point master to the latest commit of the feature branch. This is a “fast forward.”
There won't be any "merge commit" in fast-forwarding merge.
Yes, you can call setId(value)
in any view with any (positive) integer value that you like and then find it in the parent container using findViewById(value)
. Note that it is valid to call setId()
with the same value for different sibling views, but findViewById()
will return only the first one.
in your constructor you are creating another int array:
public Date(){
int[] data = {0,0,0};
}
Try this:
data = {0,0,0};
NOTE: By the way you do NOT need to initialize your array elements if it is declared as an instance variable. Instance variables automatically get their default values, which for an integer array, the default values are all zeroes.
If you had locally declared array though they you would need to initialize each element.
var result = from sc in enumerableOfSomeClass
join soc in enumerableOfSomeOtherClass
on sc.Property1 equals soc.Property2
select new { SomeClass = sc, SomeOtherClass = soc };
Would be equivalent to:
var result = enumerableOfSomeClass
.Join(enumerableOfSomeOtherClass,
sc => sc.Property1,
soc => soc.Property2,
(sc, soc) => new
{
SomeClass = sc,
SomeOtherClass = soc
});
As you can see, when it comes to joins, query syntax is usually much more readable than lambda syntax.
If it is debian based.
aptitude show postgresql | grep State
But I guess you can just try to launch it with some flag like --version
, that simply prints some info and exits.
Updated using "service postgres status". Try:
service postgres status
if [ "$?" -gt "0" ]; then
echo "Not installed".
else
echo "Intalled"

As an extension method
public static IEnumerable<TSource> AreNotEqual<TSource, TKey, TTarget>(this IEnumerable<TSource> source, Func<TSource, TKey> sourceKeySelector, IEnumerable<TTarget> target, Func<TTarget, TKey> targetKeySelector)
{
var targetValues = new HashSet<TKey>(target.Select(targetKeySelector));
return source.Where(sourceValue => targetValues.Contains(sourceKeySelector(sourceValue)) == false);
}
eg.
public class Customer
{
public int CustomerId { get; set; }
}
public class OtherCustomer
{
public int Id { get; set; }
}
var customers = new List<Customer>()
{
new Customer() { CustomerId = 1 },
new Customer() { CustomerId = 2 }
};
var others = new List<OtherCustomer>()
{
new OtherCustomer() { Id = 2 },
new OtherCustomer() { Id = 3 }
};
var result = customers.AreNotEqual(customer => customer.CustomerId, others, other => other.Id).ToList();
Debug.Assert(result.Count == 1);
Debug.Assert(result[0].CustomerId == 1);
Like Unix shells, PowerShell supports >
redirects with most of the variations known from Unix, including 2>&1
(though weirdly, order doesn't matter - 2>&1 > file
works just like the normal > file 2>&1
).
Like most modern Unix shells, PowerShell also has a shortcut for redirecting both standard error and standard output to the same device, though unlike other redirection shortcuts that follow pretty much the Unix convention, the capture all shortcut uses a new sigil and is written like so: *>
.
So your implementation might be:
& myjob.bat *>> $logfile
There is an easier solution to this problem.
You just need to add a t
to the mode so it becomes wt
. This causes Python to open the file as a text file and not binary. Then everything will just work.
The complete program becomes this:
plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wt") as outfile:
outfile.write(plaintext)
I altered Jon Skeet answer a bit for the web with extension method. It also works on azure like a charm.
public static class DateTimeWithZone
{
private static readonly TimeZoneInfo timeZone;
static DateTimeWithZone()
{
//I added web.config <add key="CurrentTimeZoneId" value="Central Europe Standard Time" />
//You can add value directly into function.
timeZone = TimeZoneInfo.FindSystemTimeZoneById(ConfigurationManager.AppSettings["CurrentTimeZoneId"]);
}
public static DateTime LocalTime(this DateTime t)
{
return TimeZoneInfo.ConvertTime(t, timeZone);
}
}
You can always do
('0' + deg).slice(-2)
See slice()
:
You can also use negative numbers to select from the end of an array
Hence
('0' + 11).slice(-2) // '11'
('0' + 4).slice(-2) // '04'
For ease of access, you could of course extract it to a function, or even extend Number
with it:
Number.prototype.pad = function(n) {
return new Array(n).join('0').slice((n || 2) * -1) + this;
}
Which will allow you to write:
c += deg.pad() + '° '; // "04° "
The above function pad
accepts an argument specifying the length of the desired string. If no such argument is used, it defaults to 2. You could write:
deg.pad(4) // "0045"
Note the obvious drawback that the value of n
cannot be higher than 11, as the string of 0's is currently just 10 characters long. This could of course be given a technical solution, but I did not want to introduce complexity in such a simple function. (Should you elect to, see alex's answer for an excellent approach to that).
Note also that you would not be able to write 2.pad()
. It only works with variables. But then, if it's not a variable, you'll always know beforehand how many digits the number consists of.
So, the idea is to convert character numbers (in single quotes, e.g. '8') to integer expression. For instance char c = '8'; int i = c - '0' //would yield integer 8; And sum up all the converted numbers by the principle that 908=9*100+0*10+8, which is done in a loop.
char t[5] = {'-', '9', '0', '8', '\0'}; //Should be terminated properly.
int s = 1;
int i = -1;
int res = 0;
if (c[0] == '-') {
s = -1;
i = 0;
}
while (c[++i] != '\0') { //iterate until the array end
res = res*10 + (c[i] - '0'); //generating the integer according to read parsed numbers.
}
res = res*s; //answer: -908
Its a very old question but I think it will help newbies line me who are learning python. If you have Python 3.4 or above, the pathlib library comes with the default distribution.
To use it, you just pass a path or filename into a new Path() object using forward slashes and it handles the rest. To indicate that the path is a raw string, put r
in front of the string with your actual path.
For example,
from pathlib import Path
dataFolder = Path(r'D:\Desktop dump\example.txt')
Source: The easy way to deal with file paths on Windows, Mac and Linux
You can refer to this page at w3schools but basically you could use any of:
<input checked>
<input checked="checked">
<input checked="">
Do it in your xml
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageButtonSettings"
android:layout_gravity="right|bottom"
android:src="@drawable/tabbar_settings_icon"
android:background="@android:color/transparent"/>
Also the complexity of concatenations of String is O(N2), while for StringBuffer it is O(N).
So there might be performance problem where we use concatenations in loops as a lot of new objects are created each time.
The Spring Framework has a class which allows to recursively search through the classpath:
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
resolver.getResources("classpath*:some/package/name/**/*.xml");
Use ,
as format specifier:
>>> format(10000.21, ',')
'10,000.21'
Alternatively you can also use str.format
instead of format
:
>>> '{:,}'.format(10000.21)
'10,000.21'

I fully agree with the vector
way when implementing a dynamic array. However, bear in mind that STL provides you with a host of containers that cater to different runtime requirements.You should choose one with care. E.g: For fast insertion at back you have the choice between a vector
and a deque
.
And I almost forgot, with great power comes great responsibility :-) Since vector
s are flexible in size, they often reallocate automagically to adjust for adding elements.So beware about iterator invalidation (yes, it applies as well to pointers). However, as long as you are using operator[]
for accessing the individual elements you are safe.
Try this
var div = document.getElementById("test");
var spans = div.getElementsByTagName("span");
for(i=0;i<spans.length;i++)
{
alert(spans[i].innerHTML);
}
SELECT IDENT_CURRENT('Table')
You can use one of these examples:
SELECT * FROM Table
WHERE ID = (
SELECT IDENT_CURRENT('Table'))
SELECT * FROM Table
WHERE ID = (
SELECT MAX(ID) FROM Table)
SELECT TOP 1 * FROM Table
ORDER BY ID DESC
But the first one will be more efficient because no index scan is needed (if you have index on Id column).
The second one solution is equivalent to the third (both of them need to scan table to get max id).
<ComboBox Text="Something">
<ComboBoxItem Content="Item1"></ComboBoxItem >
<ComboBoxItem Content="Item2"></ComboBoxItem >
<ComboBoxItem Content="Item3"></ComboBoxItem >
</ComboBox>
I was running a script from batch file as SYSTEM user and all variables like process.cwd()
, path.resolve()
and all other methods would give me path to C:\Windows\System32 folder instead of actual path. During experiments I noticed that when an error is thrown the stack contains a true path to the node file.
Here's a very hacky way to get true path by triggering an error and extracting path from e.stack. Do not use.
// this should be the name of currently executed file
const currentFilename = 'index.js';
function veryHackyGetFolder() {
try {
throw new Error();
} catch(e) {
const fullMsg = e.stack.toString();
const beginning = fullMsg.indexOf('file:///') + 8;
const end = fullMsg.indexOf('\/' + currentFilename);
const dir = fullMsg.substr(beginning, end - beginning).replace(/\//g, '\\');
return dir;
}
}
Usage
const dir = veryHackyGetFolder();
