Very simply, you can rename your Python script to "pythonscript.cgi". Post that in your cgi-bin directory, add the appropriate permissions and browse to it.
This is a great link you can start with.
Hope that helps.
EDIT (09/12/2015): The second link has long been removed. Replaced it with one that provides information referenced from the original.
As Martin Thoma has said, you need to normally apply thresholding. But you can do this using simple vectorization which will run much faster than the for loop that is used in that answer.
The code below converts the pixels of an image into 0 (black) and 1 (white).
from PIL import Image
import numpy as np
import matplotlib.pyplot as plt
#Pixels higher than this will be 1. Otherwise 0.
THRESHOLD_VALUE = 200
#Load image and convert to greyscale
img = Image.open("photo.png")
img = img.convert("L")
imgData = np.asarray(img)
thresholdedData = (imgData > THRESHOLD_VALUE) * 1.0
plt.imshow(thresholdedData)
plt.show()
You can use the CSS property pointer-events to disable the click event on any element:
https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events
// To disable:
document.getElementById('id').style.pointerEvents = 'none';
// To re-enable:
document.getElementById('id').style.pointerEvents = 'auto';
// Use '' if you want to allow CSS rules to set the value
Here is a JsBin: http://jsbin.com/oyAhuRI/1/edit
Sorry to tell you screencap just a simple command, only accept few arguments, but none of them can save time for you, here is the -h help output.
$ adb shell screencap -h
usage: screencap [-hp] [-d display-id] [FILENAME]
-h: this message
-p: save the file as a png.
-d: specify the display id to capture, default 0.
If FILENAME ends with .png it will be saved as a png.
If FILENAME is not given, the results will be printed to stdout.
Besides the command screencap, there is another command screenshot, I don't know why screenshot was removed from Android 5.0, but it's avaiable below Android 4.4, you can check the source from here. I didn't make my comparison which is faster between these two commands, but you can give your try in your real environment and make the final decision.
I was also trying to achieve this. From above codes, what I understood was that you can call getch() function multiple times in order to get both bytes getting from the function. So the ord() function is not necessary if you are just looking to use with byte objects.
while True :
if m.kbhit() :
k = m.getch()
if b'\r' == k :
break
elif k == b'\x08'or k == b'\x1b':
# b'\x08' => BACKSPACE
# b'\x1b' => ESC
pass
elif k == b'\xe0' or k == b'\x00':
k = m.getch()
if k in [b'H',b'M',b'K',b'P',b'S',b'\x08']:
# b'H' => UP ARROW
# b'M' => RIGHT ARROW
# b'K' => LEFT ARROW
# b'P' => DOWN ARROW
# b'S' => DELETE
pass
else:
print(k.decode(),end='')
else:
print(k.decode(),end='')
This code will work print any key until enter key is pressed in CMD or IDE (I was using VS CODE) You can customize inside the if for specific keys if needed
When you have many output from a function and you don't want to call it multiple times, I think the clearest way for selecting the results would be :
results = fct()
a,b = [results[i] for i in list_of_index]
As a minimum working example, also demonstrating that the function is called only once :
def fct(a):
b=a*2
c=a+2
d=a+b
e=b*2
f=a*a
print("fct called")
return[a,b,c,d,e,f]
results=fct(3)
> fct called
x,y = [results[i] for i in [1,4]]
And the values are as expected :
results
> [3,6,5,9,12,9]
x
> 6
y
> 12
For convenience, Python list indexes can also be used :
x,y = [results[i] for i in [0,-2]]
Returns : a = 3 and b = 12
Very crude, but this also works:
var Table = document.getElementById("mytable");
Table.innerHTML = "";
Right answer can be found in this (duplicate) question.
I reproduced the answer here (and it works!):
Just delete the .lock file in the .metadata directory in your eclipse workspace directory
why dont you add a "source" column to each of the queries with a static value like
select 'source 1' as Source, column1, column2...
from table1
UNION ALL
select 'source 2' as Source, column1, column2...
from table2
While working with different versions of Python on Windows,
I am using this method to switch between versions.
I think it is better than messing with shebangs and virtualenvs
1) install python versions you desire
2) go to Environment Variables > PATH
(i assume that paths of python versions are already added to Env.Vars.>PATH)
3) suppress the paths of all python versions you dont want to use
(dont delete the paths, just add a suffix like "_sup")
4) call python from terminal
(so Windows will skip the wrong paths you changed, and will find the python.exe at the path you did not suppressed, and will use this version after on)
5) switch between versions by playing with suffixes
If you want to check for a specific class then you can use
if([MyClass class] == [myClassObj class]) {
//your object is instance of MyClass
}
Your method showFile() declares that it can throw an IOException. Since this is a checked exception, any call to showFile() method must handle the exception somehow. One option is to wrap the call to showFile() in a try-catch block.
try {
showFile();
}
catch(IOException e) {
// Code to handle an IOException here
}
Use org.springframework.web.servlet.config.annotation.WebMvcConfigurer
With Spring Boot 2.1.4.RELEASE (Spring Framework 5.1.6.RELEASE), do like this
package vn.bkit;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; // Deprecated.
import org.springframework.web.servlet.view.InternalResourceViewResolver;
@Configuration
@EnableWebMvc
public class MvcConfiguration implements WebMvcConfigurer {
@Bean
public ViewResolver getViewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/");
resolver.setSuffix(".html");
return resolver;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
I have to agree with Kevin Kenny, Proggy fonts all the way, though I prefer Proggy Clean. But either way you have to go with a font that clearly shows the difference between the number 0 and the letter O. Which the preview font here doesn't really show that.
Public Function _
CreateTextArrayFromSourceTexts(ParamArray SourceTexts() As Variant) As String()
ReDim TargetTextArray(0 To UBound(SourceTexts)) As String
For SourceTextsCellNumber = 0 To UBound(SourceTexts)
TargetTextArray(SourceTextsCellNumber) = SourceTexts(SourceTextsCellNumber)
Next SourceTextsCellNumber
CreateTextArrayFromSourceTexts = TargetTextArray
End Function
Example:
Dim TT() As String
TT = CreateTextArrayFromSourceTexts("hi", "bye", "hi", "bcd", "bYe")
Result:
TT(0)="hi"
TT(1)="bye"
TT(2)="hi"
TT(3)="bcd"
TT(4)="bYe"
Enjoy!
Edit: I removed the duplicatedtexts deleting feature and made the code smaller and easier to use.
You should override Equals and GetHashCode meaningfully, in this case to compare the ID:
public class LinqTest
{
public int id { get; set; }
public string value { get; set; }
public override bool Equals(object obj)
{
LinqTest obj2 = obj as LinqTest;
if (obj2 == null) return false;
return id == obj2.id;
}
public override int GetHashCode()
{
return id;
}
}
Now you can use Distinct:
List<LinqTest> uniqueIDs = myList.Distinct().ToList();
In oracle 11g
SELECT end_date - start_date AS day_diff FROM tablexxx
suppose the starT_date end_date is define in the tablexxx
You can use the vassal package, which is exactly designed for this.
All you need is to install vassal and do
from vassal.terminal import Terminal
shell = Terminal(["scp username@host:/home/foo.txt foo_local.txt"])
shell.run()
Also, it will save you authenticate credential and don't need to type them again and again.
You can try this to avoid indicating custom date and if there is need to display start and end dates of current month:
LocalDate start = LocalDate.now().minusDays(LocalDate.now().getDayOfMonth()-1);
LocalDate end = LocalDate.now().minusDays(LocalDate.now().getDayOfMonth()).plusMonths(1);
System.out.println("Start of month: " + start);
System.out.println("End of month: " + end);
Result:
> Start of month: 2019-12-01
> End of month: 2019-12-30
If you need use React LifeCycle, you need use Class.
Sample:
import React, { Component } from 'react';
class Grid extends Component {
constructor(props){
super(props)
}
componentDidMount () { /* do something */ }
render () {
return <h1>Hello</h1>
}
}
While creating url encode them with urlencode
$val=urlencode('http://google.com/?var=234&key=234')
<a href="http://localhost/test.php?id=<?php echo $val ?>">Click here</a>
and while fetching decode it wiht urldecode
Windows.System.UserProfile.GlobalizationPreferences.Languages[0]
This is the correct way to obtain the currently set system language. System language setting is completely different than culture setting from which you all want to get the language.
For example: User may use "en-GB" language along with "en-US" culture at the same time. Using CurrentCulture and other cultures you will get "en-US", hope you get the difference (that may be innoticable with GB-US, but with other languages?)
Did you try CSS overflow property?
overflow: scroll; /* Scrollbar are always visible */
overflow: auto; /* Scrollbar is displayed as it's needed */
UPDATE
As other users are pointing out, this is not enough to add the scrollbars.
So please, see and upvote comments and answers below.
The accepted answer which was triggering input event with jQuery didn't work for me. Creating an event and dispatching with native JavaScript did the trick.
$("input")[0].dispatchEvent(new Event("input", { bubbles: true }));
volatile is a field modifier, while synchronized modifies code blocks and methods. So we can specify three variations of a simple accessor using those two keywords:
int i1; int geti1() {return i1;} volatile int i2; int geti2() {return i2;} int i3; synchronized int geti3() {return i3;}
geti1()accesses the value currently stored ini1in the current thread. Threads can have local copies of variables, and the data does not have to be the same as the data held in other threads.In particular, another thread may have updatedi1in it's thread, but the value in the current thread could be different from that updated value. In fact Java has the idea of a "main" memory, and this is the memory that holds the current "correct" value for variables. Threads can have their own copy of data for variables, and the thread copy can be different from the "main" memory. So in fact, it is possible for the "main" memory to have a value of 1 fori1, for thread1 to have a value of 2 fori1and for thread2 to have a value of 3 fori1if thread1 and thread2 have both updated i1 but those updated value has not yet been propagated to "main" memory or other threads.On the other hand,
geti2()effectively accesses the value ofi2from "main" memory. A volatile variable is not allowed to have a local copy of a variable that is different from the value currently held in "main" memory. Effectively, a variable declared volatile must have it's data synchronized across all threads, so that whenever you access or update the variable in any thread, all other threads immediately see the same value. Generally volatile variables have a higher access and update overhead than "plain" variables. Generally threads are allowed to have their own copy of data is for better efficiency.There are two differences between volitile and synchronized.
Firstly synchronized obtains and releases locks on monitors which can force only one thread at a time to execute a code block. That's the fairly well known aspect to synchronized. But synchronized also synchronizes memory. In fact synchronized synchronizes the whole of thread memory with "main" memory. So executing
geti3()does the following:
- The thread acquires the lock on the monitor for object this .
- The thread memory flushes all its variables, i.e. it has all of its variables effectively read from "main" memory .
- The code block is executed (in this case setting the return value to the current value of i3, which may have just been reset from "main" memory).
- (Any changes to variables would normally now be written out to "main" memory, but for geti3() we have no changes.)
- The thread releases the lock on the monitor for object this.
So where volatile only synchronizes the value of one variable between thread memory and "main" memory, synchronized synchronizes the value of all variables between thread memory and "main" memory, and locks and releases a monitor to boot. Clearly synchronized is likely to have more overhead than volatile.

Since .net45 you can use the LeaveOpen constructor argument of StreamWriter and still use the using statement. Example:
using (var ms = new MemoryStream())
{
using (var sw = new StreamWriter(ms, Encoding.UTF8, 1024, true))
{
sw.WriteLine("data");
sw.WriteLine("data 2");
}
ms.Position = 0;
using (var sr = new StreamReader(ms))
{
Console.WriteLine(sr.ReadToEnd());
}
}
I tried with a rest client.
Headers :
it works fine. I retrieve 200 OK with a good body.
Why do you set a status code in your request? and multiple declaration "Accept" with Accept:application/json,application/json,application/jsonrequest. just a statement is enough.
GZip Compression can be enabled directly through IIS.
First, open up IIS,
go to the website you are hoping to tweak and hit the Compression page. If Gzip is not installed, you will see something like the following:
“The dynamic content compression module is not installed.” We should fix this. So we go to the “Turn Windows features on or off” and select “Dynamic Content Compression” and click the OK button.
Now if we go back to IIS, we should see that the compression page has changed. At this point we need to make sure the dynamic compression checkbox is checked and we’re good to go. Compression is enabled and our dynamic content will be Gzipped.
Testing - Check if GZIP Compression is Enabled
To test whether compression is working or not, use the developer tools in Chrome or Firebug for Firefox and ensure the HTTP response header is set:
Content-Encoding: gzip
Yeah, your current solution is prone to SQL injection attacks.
The best solution that I've found is to use a function that splits text into words (there are a few posted here, or you can use this one from my blog) and then join that to your table. Something like:
SELECT d.[Name]
FROM Department d
JOIN dbo.SplitWords(@DepartmentIds) w ON w.Value = d.DepartmentId

This question is very, very, very old, but as a trick in the future, I recommend something like this:
.element{
box-shadow: 0px 0px 10px #232931;
}
.container{
height: 100px;
width: 100px;
overflow: hidden;
}
Basically, you have a box shadow and then wrapping the element in a div with its overflow set to hidden. You'll need to adjust the height, width, and even padding of the div to only show the left box shadow, but it works. See here for an example If you look at the example, you can see how there's no other shadows, but only a black left shadow. Edit: this is a retake of the same screen shot, in case some one thinks that I just cropped out the right. You can find it here
There is a library ng-device-detector which makes detecting entities like browser, os easy.
Here is tutorial that explains how to use this library. Detect OS, browser and device in AngularJS
You need to add re-tree.js and ng-device-detector.js scripts into your html
Inject "ng.deviceDetector" as dependency in your module.
Then inject "deviceDetector" service provided by the library into your controller or factory where ever you want the data.
"deviceDetector" contains all data regarding browser, os and device.
Seems to me that the right formula should be:
n64 = 4 * (n / 3) + (n % 3 != 0 ? 4 : 0)

tableView.endUpdates()
the keyboard disappear

You need to specify it on the methods that can throw the exceptions. You just seperate them with a ',' if it can throw more than 1 type of exception. e.g.
public interface MyInterface {
public MyObject find(int x) throws MyExceptionA,MyExceptionB;
}
I extracted the code and put into one single method, hope it would help others.

Because a dictionary is a single value. You need to use keyword expansion if you want to pass it as a group of keyword arguments.
If you want to retrieve POST data:
first_name = request.form.get("firstname")
If you want to retrieve GET (query string) data:
first_name = request.args.get("firstname")
Or if you don't care/know whether the value is in the query string or in the post data:
first_name = request.values.get("firstname")
request.values is a CombinedMultiDict that combines Dicts from request.form and request.args.
Legacy. List was originally defined to be functional-languages-looking:
1 :: 2 :: Nil // a list
list1 ::: list2 // concatenation of two lists
list match {
case head :: tail => "non-empty"
case Nil => "empty"
}
Of course, Scala evolved other collections, in an ad-hoc manner. When 2.8 came out, the collections were redesigned for maximum code reuse and consistent API, so that you can use ++ to concatenate any two collections -- and even iterators. List, however, got to keep its original operators, aside from one or two which got deprecated.

A cleaner alternative of putting your config file into a subfolder of src/main/resources would be to enhance your classpath locations. This is extremely easy to do with Maven.
For instance, place your property file in a new folder src/main/config, and add the following to your pom:
<build>
<resources>
<resource>
<directory>src/main/config</directory>
</resource>
</resources>
</build>
From now, every files files under src/main/config is considered as part of your classpath (note that you can exclude some of them from the final jar if needed: just add in the build section:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<excludes>
<exclude>my-config.properties</exclude>
</excludes>
</configuration>
</plugin>
</plugins>
so that my-config.properties can be found in your classpath when you run your app from your IDE, but will remain external from your jar in your final distribution).
You can't use add_timestamps and null:false if you have existing records, so here is the solution :
def change
add_timestamps(:buttons, null: true)
Button.find_each { |b| b.update(created_at: Time.zone.now, updated_at: Time.zone.now) }
change_column_null(:buttons, :created_at, false)
change_column_null(:buttons, :updated_at, false)
end
Why not just reload the page when the user rotates the screen with javascript

My site is hosted on MochaHost, i had a tough time to setup the .htaccess file so that i can remove the index.php from my urls. However, after some googling, i combined the answer on this thread and other answers. My final working .htaccess file has the following contents:
<IfModule mod_rewrite.c>
# Turn on URL rewriting
RewriteEngine On
# If your website begins from a folder e.g localhost/my_project then
# you have to change it to: RewriteBase /my_project/
# If your site begins from the root e.g. example.local/ then
# let it as it is
RewriteBase /
# Protect application and system files from being viewed when the index.php is missing
RewriteCond $1 ^(application|system|private|logs)
# Rewrite to index.php/access_denied/URL
RewriteRule ^(.*)$ index.php/access_denied/$1 [PT,L]
# Allow these directories and files to be displayed directly:
RewriteCond $1 ^(index\.php|robots\.txt|favicon\.ico|public|app_upload|assets|css|js|images)
# No rewriting
RewriteRule ^(.*)$ - [PT,L]
# Rewrite to index.php/URL
RewriteRule ^(.*)$ index.php?/$1 [PT,L]

Is NDEBUG standard?
Yes it is a standard macro with the semantic "Not Debug" for C89, C99, C++98, C++2003, C++2011, C++2014 standards. There are no _DEBUG macros in the standards.
C++2003 standard send the reader at "page 326" at "17.4.2.1 Headers" to standard C.
That NDEBUG is similar as This is the same as the Standard C library.
In C89 (C programmers called this standard as standard C) in "4.2 DIAGNOSTICS" section it was said
http://port70.net/~nsz/c/c89/c89-draft.html
If NDEBUG is defined as a macro name at the point in the source file where is included, the assert macro is defined simply as
#define assert(ignore) ((void)0)
If look at the meaning of _DEBUG macros in Visual Studio
https://msdn.microsoft.com/en-us/library/b0084kay.aspx
then it will be seen, that this macro is automatically defined by your ?hoice of language runtime library version.
import tarfile
tar = tarfile.open("sample.tar.gz", "w:gz")
for name in ["file1", "file2", "file3"]:
tar.add(name)
tar.close()
If you want to create a tar.bz2 compressed file, just replace file extension name with ".tar.bz2" and "w:gz" with "w:bz2".
It sounds like you want to list all the metrics?
SELECT Criteria1, Criteria2, Metric1 As Metric
FROM Table1
UNION ALL
SELECT Criteria1, Criteria2, Metric2 As Metric
FROM Table2
ORDER BY 1, 2
If you only want one Criteria1+Criteria2 combination, group them:
SELECT Criteria1, Criteia2, SUM(Metric) AS Metric
FROM (
SELECT Criteria1, Criteria2, Metric1 As Metric
FROM Table1
UNION ALL
SELECT Criteria1, Criteria2, Metric2 As Metric
FROM Table2
)
ORDER BY Criteria1, Criteria2
You can set this using the Sys.setenv() function. My R session defaults to English, so I'll set it to French and then back again:
> Sys.setenv(LANG = "fr")
> 2 + x
Erreur : objet 'x' introuvable
> Sys.setenv(LANG = "en")
> 2 + x
Error: object 'x' not found
A list of the abbreviations can be found here.
Sys.getenv() gives you a list of all the environment variables that are set.
AutoCloseable (introduced in Java 7) makes it possible to use the try-with-resources idiom:
public class MyResource implements AutoCloseable {
public void close() throws Exception {
System.out.println("Closing!");
}
}
Now you can say:
try (MyResource res = new MyResource()) {
// use resource here
}
and JVM will call close() automatically for you.
Closeable is an older interface. For some reason To preserve backward compatibility, language designers decided to create a separate one. This allows not only all Closeable classes (like streams throwing IOException) to be used in try-with-resources, but also allows throwing more general checked exceptions from close().
When in doubt, use AutoCloseable, users of your class will be grateful.
I have implemented the function to install and load required R packages silently. Hope might help. Here is the code:
# Function to Install and Load R Packages
Install_And_Load <- function(Required_Packages)
{
Remaining_Packages <- Required_Packages[!(Required_Packages %in% installed.packages()[,"Package"])];
if(length(Remaining_Packages))
{
install.packages(Remaining_Packages);
}
for(package_name in Required_Packages)
{
library(package_name,character.only=TRUE,quietly=TRUE);
}
}
# Specify the list of required packages to be installed and load
Required_Packages=c("ggplot2", "Rcpp");
# Call the Function
Install_And_Load(Required_Packages);
try this code:
.absolute {
position: absolute;
top: 0; left: 0;
width: 200px;
height: 50px;
background: yellow;
}
Its a parameter the you need to define. to prevent SQL Injection you should pass all your variables in as parameters.
You will also need to set 100% height on the html element:
html { height:100%; }
In my case I had a problem with the Available Package Sources. I had move the local nuget repository folder to a new path but I did not update it in the Nuget Available Package Sources. When I've correct the path issue, update it in the Available Package Sources and after that everything (nuget restor, etc) was working fine.
Write a Java program to create an array of 20 integers, and then implement the process of shifting the array to right for two elements.
public class NewClass3 {
public static void main (String args[]){
int a [] = {1,2,};
int temp ;
for(int i = 0; i<a.length -1; i++){
temp = a[i];
a[i] = a[i+1];
a[i+1] = temp;
}
for(int p : a)
System.out.print(p);
}
}
I would suggest the following:
String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); After multiple trials here is how I got it working for what I wanted. This is what I was trying. - I have a view with a image. and I wanted to have the image go full screen. - I have a navigation controller with a tabBar too. So i need to hide that too. - Also, my main requirement was not just hiding, but having a fading effect too while showing and hiding.
This is how I got it working.
Step 1 - I have a image and user taps on that image once. I capture that gesture and push it into the new imageViewController, its in the imageViewController, I want to have full screen image.
- (void)handleSingleTap:(UIGestureRecognizer *)gestureRecognizer {
NSLog(@"Single tap");
ImageViewController *imageViewController =
[[ImageViewController alloc] initWithNibName:@"ImageViewController" bundle:nil];
godImageViewController.imgName = // pass the image.
godImageViewController.hidesBottomBarWhenPushed=YES;// This is important to note.
[self.navigationController pushViewController:godImageViewController animated:YES];
// If I remove the line below, then I get this error. [CALayer retain]: message sent to deallocated instance .
// [godImageViewController release];
}
Step 2 - All these steps below are in the ImageViewController
Step 2.1 - In ViewDidLoad, show the navBar
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
NSLog(@"viewDidLoad");
[[self navigationController] setNavigationBarHidden:NO animated:YES];
}
Step 2.2 - In viewDidAppear, set up a timer task with delay ( I have it set for 1 sec delay). And after the delay, add fading effect. I am using alpha to use fading.
- (void)viewDidAppear:(BOOL)animated
{
NSLog(@"viewDidAppear");
myTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(fadeScreen) userInfo:nil repeats:NO];
}
- (void)fadeScreen
{
[UIView beginAnimations:nil context:nil]; // begins animation block
[UIView setAnimationDuration:1.95]; // sets animation duration
self.navigationController.navigationBar.alpha = 0.0; // Fades the alpha channel of this view to "0.0" over the animationDuration of "0.75" seconds
[UIView commitAnimations]; // commits the animation block. This Block is done.
}
step 2.3 - Under viewWillAppear, add singleTap gesture to the image and make the navBar translucent.
- (void) viewWillAppear:(BOOL)animated
{
NSLog(@"viewWillAppear");
NSString *path = [[NSBundle mainBundle] pathForResource:self.imgName ofType:@"png"];
UIImage *theImage = [UIImage imageWithContentsOfFile:path];
self.imgView.image = theImage;
// add tap gestures
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
[self.imgView addGestureRecognizer:singleTap];
[singleTap release];
// to make the image go full screen
self.navigationController.navigationBar.translucent=YES;
}
- (void)handleTap:(UIGestureRecognizer *)gestureRecognizer
{
NSLog(@"Handle Single tap");
[self finishedFading];
// fade again. You can choose to skip this can add a bool, if you want to fade again when user taps again.
myTimer = [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(fadeScreen) userInfo:nil repeats:NO];
}
Step 3 - Finally in viewWillDisappear, make sure to put all the stuff back
- (void)viewWillDisappear: (BOOL)animated
{
self.hidesBottomBarWhenPushed = NO;
self.navigationController.navigationBar.translucent=NO;
if (self.navigationController.topViewController != self)
{
[self.navigationController setNavigationBarHidden:NO animated:animated];
}
[super viewWillDisappear:animated];
}
TCP has a feature called "TIME_WAIT" that ensures connections are closed cleanly. It requires one end of the connection to stay listening for a while after the socket has been closed.
In a high-performance server, it's important that it's the clients who go into TIME_WAIT, not the server. Clients can afford to have a port open, whereas a busy server can rapidly run out of ports or have too many open FDs.
To achieve this, the server should never close the connection first -- it should always wait for the client to close it.
use default js match() function:
if( element.attr('class') !== undefined && element.attr('class').match(/class1|class2|class3|class4|class5/) ) {
console.log("match");
}
to use variables in regexp, use this:
var reg = new RegExp(variable, 'g');
$(this).match(reg);
by the way, this is the fastest way: http://jsperf.com/hasclass-vs-is-stackoverflow/22
In the first case, the data are passed to the script via GET, in the second via POST.

Updated Answer for Changed Documentation
The information is now spread across several guides in the documentation. Here's a list of required reading:
The answer to this question now depends entirely on whether you're using an ARC-managed application (the modern default for new projects) or forcing manual memory management.
Assign vs. Weak - Use assign to set a property's pointer to the address of the object without retaining it or otherwise curating it; use weak to have the property point to nil automatically if the object assigned to it is deallocated. In most cases you'll want to use weak so you're not trying to access a deallocated object (illegal access of a memory address - "EXC_BAD_ACCESS") if you don't perform proper cleanup.
Retain vs. Copy - Declared properties use retain by default (so you can simply omit it altogether) and will manage the object's reference count automatically whether another object is assigned to the property or it's set to nil; Use copy to automatically send the newly-assigned object a -copy message (which will create a copy of the passed object and assign that copy to the property instead - useful (even required) in some situations where the assigned object might be modified after being set as a property of some other object (which would mean that modification/mutation would apply to the property as well).
It seems that in VBA macro code for an ActiveX checkbox control you use
If (ActiveSheet.OLEObjects("CheckBox1").Object.Value = True)
and for a Form checkbox control you use
If (ActiveSheet.Shapes("CheckBox1").OLEFormat.Object.Value = 1)
I understand your problem boils down to how to call a SOAP (JAX-WS) web service from Java and get its returning object. In that case, you have two possible approaches:
wsimport and use them; or
About the first approach (using wsimport):
I see you already have the services' (entities or other) business classes, and it's a fact that the wsimport generates a whole new set of classes (that are somehow duplicates of the classes you already have).
I'm afraid, though, in this scenario, you can only either:
wsimport generated code to make it use your business classes (this is difficult and somehow not worth it - bear in mind everytime the WSDL changes, you'll have to regenerate and readapt the code); orwsimport generated classes. (In this solution, you business code could "use" the generated classes as a service from another architectural layer.)About the second approach (create your custom SOAP client):
In order to implement the second approach, you'll have to:
java.net.HttpUrlconnection (and some java.io handling).Creating a SOAP client using classic java.net.HttpUrlConnection is not that hard (but not that simple either), and you can find in this link a very good starting code.
I recommend you use the SAAJ framework:
SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.
See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.
import javax.xml.soap.*;
public class SOAPClientSAAJ {
// SAAJ - SOAP Client Testing
public static void main(String args[]) {
/*
The example below requests from the Web Service at:
https://www.w3schools.com/xml/tempconvert.asmx?op=CelsiusToFahrenheit
To call other WS, change the parameters below, which are:
- the SOAP Endpoint URL (that is, where the service is responding from)
- the SOAP Action
Also change the contents of the method createSoapEnvelope() in this class. It constructs
the inner part of the SOAP envelope that is actually sent.
*/
String soapEndpointUrl = "https://www.w3schools.com/xml/tempconvert.asmx";
String soapAction = "https://www.w3schools.com/xml/CelsiusToFahrenheit";
callSoapWebService(soapEndpointUrl, soapAction);
}
private static void createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
SOAPPart soapPart = soapMessage.getSOAPPart();
String myNamespace = "myNamespace";
String myNamespaceURI = "https://www.w3schools.com/xml/";

SOAPEnvelope envelope = soapPart.getEnvelope();
envelope.addNamespaceDeclaration(myNamespace, myNamespaceURI);

About using JAXB for serializing/deserializing, it is very easy to find information about it. You can start here: http://www.mkyong.com/java/jaxb-hello-world-example/.
You could try to save the image using this approach
SaveFileDialog dialog = new SaveFileDialog();
if (dialog.ShowDialog() == DialogResult.OK)
{
int width = Convert.ToInt32(drawImage.Width);
int height = Convert.ToInt32(drawImage.Height);
Bitmap bmp = new Bitmap(width,height);
drawImage.DrawToBitmap(bmp, new Rectangle(0, 0, width, height);
bmp.Save(dialog.FileName, ImageFormat.Jpeg);
}
The original checked attribute (HTML 4 and before) did not require a value on it - if it existed, the element was "checked", if not, it wasn't.
This, however is not valid for XHTML that followed HTML 4.
The standard proposed to use checked="checked" as a condition for true - so both ways you posted end up doing the same thing.
It really doesn't matter which one you use - use the one that makes most sense to you and stick to it (or agree with your team which way to go).
in ViewGroup you can add some other Views as child. ViewGroup is the base class for layouts and view containers.
<table id="myData">
</table>
<script type="text/javascript">
$('#search').click(function() {
alert("submit handler has fired");
$.ajax({
type: 'POST',
url: 'cityResults.htm',
data: $('#cityDetails').serialize(),
success: function(data){
$.each(data, function( index, value ) {
var row = $("<tr><td>" + value.city + "</td><td>" + value.cStatus + "</td></tr>");
$("#myData").append(row);
});
},
error: function(jqXHR, textStatus, errorThrown){
alert('error: ' + textStatus + ': ' + errorThrown);
}
});
return false;//suppress natural form submission
});
</script>
loop through the data and append it to a table like the code above.
Simple 2020 no-tricks method:

display: flex;
flex-direction: column;
}
#footer {
margin-top: auto;
}
Better:
Integer.valueOf(i).toString()
This one worked for me:
(?P<value>[-+]*\d+\.\d+|[-+]*\d+)
You can also use this one (without named parameter):
([-+]*\d+\.\d+|[-+]*\d+)
Use some online regex tester to test it (e.g. regex101 )

Based on zapl's answer, adding try() around Closeable's closes the streams automatically after use.
public static void unzip(File zipFile, File targetDirectory) {
try (FileInputStream fis = new FileInputStream(zipFile)) {
try (BufferedInputStream bis = new BufferedInputStream(fis)) {
try (ZipInputStream zis = new ZipInputStream(bis)) {
ZipEntry ze;
int count;
byte[] buffer = new byte[Constant.DefaultBufferSize];
while ((ze = zis.getNextEntry()) != null) {
File file = new File(targetDirectory, ze.getName());
File dir = ze.isDirectory() ? file : file.getParentFile();
if (!dir.isDirectory() && !dir.mkdirs())
throw new FileNotFoundException("Failed to ensure directory: " + dir.getAbsolutePath());
if (ze.isDirectory())
continue;
try (FileOutputStream fout = new FileOutputStream(file)) {
while ((count = zis.read(buffer)) != -1)
fout.write(buffer, 0, count);
}
}
}
}
} catch (Exception ex) {
//handle exception
}
}
Using Constant.DefaultBufferSize (65536) gotten from C# .NET 4 Stream.CopyTo from Jon Skeet's answer here:
https://stackoverflow.com/a/411605/1876355
I always just see posts using byte[1024] or byte[4096] buffer, never knew it can be much larger which improves performance and is still working perfectly normal.
Here is the Stream Source code:
https://referencesource.microsoft.com/#mscorlib/system/io/stream.cs
//We pick a value that is the largest multiple of 4096 that is still smaller than the large object heap threshold (85K). // The CopyTo/CopyToAsync buffer is short-lived and is likely to be collected at Gen0, and it offers a significant // improvement in Copy performance. private const int _DefaultCopyBufferSize = 81920;
However, I dialed it back to 65536 which is also a multiple of 4096 just to be safe.
Empty strings are "falsy" which means they are considered false in a Boolean context, so you can just do this:
if not myString:
This is the preferred way if you know that your variable is a string. If your variable could also be some other type then you should use myString == "". See the documentation on Truth Value Testing for other values that are false in Boolean contexts.
There's no need to add space before closing quote if path doesn't contain trailing backslash, so following command should work:
robocopy "C:\Source Path" "C:\Destination Path" /option1 /option2...
But, following will not work:
robocopy "C:\Source Path\" "C:\Destination Path\" /option1 /option2...
This is due to the escaping issue that is described here:
The \ escape can cause problems with quoted directory paths that contain a trailing backslash because the closing quote " at the end of the line will be escaped \".
It is better to use implode for that purpose. Implode is easy and awesome:
$array = ['name1', 'name2', 'name3'];
$str = implode(', ', $array);
Output:
name1, name2, name3

Include required imports and you can make ur decision in handleError method Error status will give the error code
import { HttpClient, HttpErrorResponse } from '@angular/common/http';
import {Observable, throwError} from "rxjs/index";
import { catchError, retry } from 'rxjs/operators';
import {ApiResponse} from "../model/api.response";
import { TaxType } from '../model/taxtype.model';
private handleError(error: HttpErrorResponse) {
if (error.error instanceof ErrorEvent) {
// A client-side or network error occurred. Handle it accordingly.
console.error('An error occurred:', error.error.message);
} else {
// The backend returned an unsuccessful response code.
// The response body may contain clues as to what went wrong,
console.error(
`Backend returned code ${error.status}, ` +
`body was: ${error.error}`);
}
// return an observable with a user-facing error message
return throwError(
'Something bad happened; please try again later.');
};
getTaxTypes() : Observable<ApiResponse> {
return this.http.get<ApiResponse>(this.baseUrl).pipe(
catchError(this.handleError)
);
}
If you haven't yet commited the changes, then:
git diff > mypatch.patch
But sometimes it happens that part of the stuff you're doing are new files that are untracked and won't be in your git diff output. So, one way to do a patch is to stage everything for a new commit (git add each file, or just git add .) but don't do the commit, and then:
git diff --cached > mypatch.patch
Add the 'binary' option if you want to add binary files to the patch (e.g. mp3 files):
git diff --cached --binary > mypatch.patch
You can later apply the patch:
git apply mypatch.patch
I know this is quite an old one, but I faced similar issue and resolved it in a different way. The actuator-autoconfigure pom somehow was invalid and so it was throwing IllegalStateException. I removed the actuator* dependencies from my maven repo and did a Maven update in eclipse, which then downloaded the correct/valid dependencies and resolved my issue.
The characteristics of sets in Python are that the data items in a set are unordered and duplicates are not allowed. If you try to add a data item to a set that already contains the data item, Python simply ignores it.
>>> l = ['a', 'a', 'bb', 'b', 'c', 'c', '10', '10', '8','8', 10, 10, 6, 10, 11.2, 11.2, 11, 11]
>>> distinct_l = set(l)
>>> print(distinct_l)
set(['a', '10', 'c', 'b', 6, 'bb', 10, 11, 11.2, '8'])
Update: It finally made it into JavaScript (ECMAScript 2018)!
Named capturing groups could make it into JavaScript very soon.
The proposal for it is at stage 3 already.
A capture group can be given a name inside angular brackets using the (?<name>...) syntax, for
any identifier name. The regular expression for a date then can be
written as /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/u. Each name
should be unique and follow the grammar for ECMAScript IdentifierName.
Named groups can be accessed from properties of a groups property of the regular expression result. Numbered references to the groups are also created, just as for non-named groups. For example:
let re = /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/u;
let result = re.exec('2015-01-02');
// result.groups.year === '2015';
// result.groups.month === '01';
// result.groups.day === '02';
// result[0] === '2015-01-02';
// result[1] === '2015';
// result[2] === '01';
// result[3] === '02';
Split the CSV into two files in Notepad. It's a pain, but you can just edit each of them individually in Excel after that.
I followed tim peterson's instructions but I created a local branch for my changes. However, after pushing I was not seeing the new branch in GitHub. The solution was to add -u to the push command:
git push -u origin <branch>
javac only compiles the code. You need to use java command to run the code. The error is because your classpath doesn't contain the class Subclass iwhen you tried to compile it. you need to add them with the -cp variable in javac command
java -cp classpath-entries mainjava arg1 arg2 should run your code with 2 arguments
People have already mentioned ternary expressions. Sometimes with a simple conditional assignment as your example, it is possible to use a mathematical expression to perform the conditional assignment. This may not make your code very readable, but it does get it on one fairly short line. Your example could be written like this:
x = 2*(i>100) | 1*(i<100)
The comparisons would be True or False, and when multiplying with numbers would then be either 1 or 0. One could use a + instead of an | in the middle.
You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.
Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.
You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.
The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.
You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.
Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.
But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).
You should provide @2x images for the Retina Macbook Pro and future Retina Macs.
Please try this. You will understand all perfectly after you will take a look on my solution.
There are only 2 ways of creating threads in java
with implements Runnable
class One implements Runnable {
@Override
public void run() {
System.out.println("Running thread 1 ... ");
}
with extends Thread
class Two extends Thread {
@Override
public void run() {
System.out.println("Running thread 2 ... ");
}
Your MAIN class here
public class ExampleMain {
public static void main(String[] args) {
One demo1 = new One();
Thread t1 = new Thread(demo1);
t1.start();
Two demo2 = new Two();
Thread t2 = new Thread(demo2);
t2.start();
}
}
Backgrounds jobs are expensive to setup and are not reusable. PowerShell MVP Oisin Grehan has a good example of PowerShell multi-threading.
(10/25/2010 site is down, but accessible via the Web Archive).
I'e used adapted Oisin script for use in a data loading routine here:

I think the actual number really depends on what makes logical sense with the context of the function. I agree that around 4-5 parameters starts getting crowded.
In the case of setting flags, a great way to handle this situation is to enumerate the values and OR them together.
Only one process can use port 80 at a time. Port 80 is the default port for web servers, so when you navigate to websites over HTTP, you are actually navigating to that server's port 80 by default (when you use HTTPS, the port is 443).
You can try to hunt down all the programs that are running on port 80, but there's an easier way that will work for development. When running XAMPP, click "Config" under "Apache". Replace Listen 80 with Listen 8080 and ServerName localhost:80 to ServerName localhost:8080.
Then, when you want to look at your masterpiece, navigate to http://localhost:8080 in your browser.
MultipartFile multipartFile = new MockMultipartFile("test.xlsx", new FileInputStream(new File("/home/admin/test.xlsx")));
This code works fine for me. May be you can have a try.
For the Record:
Note that in PHP the switch statement is considered a looping structure for the purposes of continue.
I have turned the accepted answer into a robust script. You'll find it in my git-extensions repository.

To complement Alex's response, I would add that starting from Python 2.2.0a2, from __future__ import division is a convenient alternative to using lots of float(…)/…. All divisions perform float divisions, except those with //. This works with all versions from 2.2.0a2 on.
std::unique_ptr has no copy constructor. You create an instance and then ask the std::vector to copy that instance during initialisation.
error: deleted function 'std::unique_ptr<_Tp, _Tp_Deleter>::uniqu
e_ptr(const std::unique_ptr<_Tp, _Tp_Deleter>&) [with _Tp = int, _Tp_D
eleter = std::default_delete<int>, std::unique_ptr<_Tp, _Tp_Deleter> =
std::unique_ptr<int>]'
The class satisfies the requirements of MoveConstructible and MoveAssignable, but not the requirements of either CopyConstructible or CopyAssignable.
The following works with the new emplace calls.
std::vector< std::unique_ptr< int > > vec;
vec.emplace_back( new int( 1984 ) );
See using unique_ptr with standard library containers for further reading.
In C# 4, you will be able to use built-in support for tuples to handle this easily.
In the meantime, there are two options.
First, you can use ref or out parameters to assign values to your parameters, which get passed back to the calling routine.
This looks like:
void myFunction(ref int setMe, out int youMustSetMe);
Second, you can wrap up your return values into a structure or class, and pass them back as members of that structure. KeyValuePair works well for 2 - for more than 2 you would need a custom class or struct.
If you don't have .NET 5.0, extend the DateTime class to include week number.
public static class Extension {
public static int Week(this DateTime date) {
var day = (int)CultureInfo.CurrentCulture.Calendar.GetDayOfWeek(date);
return CultureInfo.CurrentCulture.Calendar.GetWeekOfYear(date.AddDays(4 - (day == 0 ? 7 : day)), CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);
}
}
I solved this error "Compilation failed to see the compiler error output for details"
The solution is very Simple: Add in a Gradle below a line of code
implementation 'com.google.android.gms:play-services-ads:15.0.0'
Apply style="text-align: right" to the input tag. This will allow entry to be right-justified, and (at least in Firefox 3, IE 7 and Safari) will even appear to flow from the right.
This is the solution:
export default Home;
The problem here is that in your code the program is calling 'null.length()' which is not defined if the argument passed to the function is null. That's why the exception is thrown.

My Spring boot application has two initializers. One for development and another for production. For development, I use the main method like this:
@SpringBootApplication
public class MyAppInitializer {
public static void main(String[] args) {
SpringApplication.run(MyAppInitializer .class, args);
}
}
My Initializer for production environment extends the SpringBootServletInitializer and looks like this:
@SpringBootApplication
public class MyAppInitializerServlet extends SpringBootServletInitializer{
private static final Logger log = Logger
.getLogger(SpringBootServletInitializer.class);
@Override
protected SpringApplicationBuilder configure(
SpringApplicationBuilder builder) {
log.trace("Initializing the application");
return builder.sources(MyAppInitializerServlet .class);
}
}
I use gradle and my build.gradle file applies 'WAR' plugin. When I run it in the development environment, I use bootrun task. Where as when I want to deploy it to production, I use assemble task to generate the WAR and deploy.
I can run like a normal spring application in production without discounting the advantages provided by the inbuilt tomcat while developing. Hope this helps.
Best as an out parameter:
void testfunc(char* outStr){
char str[10];
for(int i=0; i < 10; ++i){
outStr[i] = str[i];
}
}
Called with
int main(){
char myStr[10];
testfunc(myStr);
// myStr is now filled
}
site-packages is the target directory of manually built Python packages. When you build and install Python packages from source (using distutils, probably by executing python setup.py install), you will find the installed modules in site-packages by default.
There are standard locations:
prefix/lib/pythonX.Y/site-packagesexec-prefix/lib/pythonX.Y/site-packagesprefix\Lib\site-packages1 Pure means that the module uses only Python code. Non-pure can contain C/C++ code as well.
site-packages is by default part of the Python search path, so modules installed there can be imported easily afterwards.
The answer by Kleist certainly works, but there is an important caveat:
When you write a Makefile manually, you might generate a SRCS variable using a function to select all .cpp and .h files. If a source file is later added, re-running make will include it.
However, CMake (with a command like file(GLOB ...)) will explicitly generate a file list and place it in the auto-generated Makefile. If you have a new source file, you will need to re-generate the Makefile by re-running cmake.
edit: No need to remove the Makefile.
In the HTML file itself, modify the background-color of the jumbotron using the style attribute:

This is a general rambling on Parallelism in SQL Server, it might not answer your question directly.
From Books Online, on MAXDOP:
Sets the maximum number of processors the query processor can use to execute a single index statement. Fewer processors may be used depending on the current system workload.
See Rickie Lee's blog on parallelism and CXPACKET wait type. It's quite interesting.
Generally, in an OLTP database, my opinion is that if a query is so costly it needs to be executed on several processors, the query needs to be re-written into something more efficient.
Why you get better results adding MAXDOP(1)? Hard to tell without the actual execution plans, but it might be so simple as that the execution plan is totally different that without the OPTION, for instance using a different index (or more likely) JOINing differently, using MERGE or HASH joins.

For me this problem arised while trying to connect to the SAP Hana database. When I got this error,
OperationalError: Lost connection to HANA server (ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))
I tried to run the code for connection(mentioned below), which created that error, again and it worked.
import pyhdb
connection = pyhdb.connect(host="example.com",port=30015,user="user",password="secret")
cursor = connection.cursor()
cursor.execute("SELECT 'Hello Python World' FROM DUMMY")
cursor.fetchone()
connection.close()
It was because the server refused to connect. It might require you to wait for a while and try again. Try closing the Hana Studio by logging off and then logging in again. Keep running the code for a number of times.
You could try one of two things or a combination of both.
I hope this helps someone
function isset(element) {
return element.length > 0;
}
Or, as a jQuery extension:
$.fn.exists = function() { return this.length > 0; };
// later ...
if ( $("#id").exists() ) {
// do something
}
I agree with Cade Roux.
This article should get you on the right track:
One thing to note, clustered indexes should have a unique key (an identity column I would recommend) as the first column. Basically it helps your data insert at the end of the index and not cause lots of disk IO and Page splits.
Secondly, if you are creating other indexes on your data and they are constructed cleverly they will be reused.
e.g. imagine you search a table on three columns
state, county, zip.
Then an index with state, county, zip. will be used in all three of these searches.
If you search by zip alone quite a lot then the above index will not be used (by SQL Server anyway) as zip is the third part of that index and the query optimiser will not see that index as helpful.
You could then create an index on Zip alone that would be used in this instance.
By the way We can take advantage of the fact that with Multi-Column indexing the first index column is always usable for searching and when you search only by 'state' it is efficient but yet not as efficient as Single-Column index on 'state'
I guess the answer you are looking for is that it depends on your where clauses of your frequently used queries and also your group by's.
The article will help a lot. :-)
There are a few issues here. Firstly, the async load method you specified:
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load('jquery', '1.3.1');
google.setOnLoadCallback(function() {
// do stuff
});
</script>
has a couple of issues. Script tags pause the page load while they are retrieved (if necessary). Now if they're slow to load this is bad but jQuery is small. The real problem with the above method is that because the jquery.js load happens independently for many pages, they will finish loading and render before jquery has loaded so any jquery styling you do will be a visible change for the user.
The other way is:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js"></script>
Try some simple examples like, have a simple table and change the background of the cells to yellow with the setOnLoadCallback() method vs $(document).ready() with a static jquery.min.js load. The second method will have no noticeable flicker. The first will. Personally I think that's not a good user experience.
As an example run this:
<html>
<head>
<title>Layout</title>
<style type="text/css">
.odd { background-color: yellow; }
</style>
</head>
<body>
<table>
<tr><th>One</th><th>Two</th></tr>
<tr><td>Three</td><td>Four</td></tr>
<tr><td>Five</td><td>Six</td></tr>
<tr><td>Seven</td><td>Nine</td></tr>
<tr><td>Nine</td><td>Ten</td></tr>
</table>
<script src="http://www.google.com/jsapi"></script>
<script>
google.load("jquery", "1.3.1");
google.setOnLoadCallback(function() {
$(function() {
$("tr:odd").addClass("odd");
});
});
</script>
</body>
</html>
You (should) see the table appear and then the rows go yellow.
The second problem with the google.load() method is that it only hosts a limited range of files. This is a problem for jquery since it is extremely plug-in dependent. If you try and include a jquery plugin with a <script src="..."> tag and google.load() the plug-in will probably fail with messages of "jQuery is not defined" because it hasn't loaded yet. I don't really see a way around this.
The third problem (with either method) is that they are one external load. Assuming you have some plugins and your own Javascript code you're up to a minimum of two external requests to load your Javascript. You're probably better off getting jquery, all relevant plug-ins and your own code and putting it into one minified file.
From Should You Use Google's Ajax Libraries API for Hosting?:
As to load times, you're actually loading two scripts - the jsapi script and the mootools script (the compressed version from above). So that is two connections, rather than one. In my experience, I found that the load time was actually 2-3 times slower than loading from my own personal shared server, even though it was coming from Google, and my version of the compressed file was a couple of K larger than Google's. This, even after the file had loaded and (presumably) cached. So for me, since the bandwidth doesn't matter much, isn't going to matter.
Lastly you have the potential problem of a paranoid browser flagging the request as some sort of XSS attempt. It's not typically a problem with default settings but on corporate networks where the user may not have control over which browser they use let alone the security settings you may have a problem.
So in the end I can't really see me using the Google AJAX API for jQuery at least (the more "complete" APIs are a different story in some ways) much except to post examples here.
you need to place the opening brace after main , not before it
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(void)
{
Also, RUN AS ADMINISTRATOR! Worked for me with backslash fix.
Using solve with a single parameter is a request to invert a matrix. The error message is telling you that your matrix is singular and cannot be inverted.
Try this. I set the blue box to float right, gave left and right a fixed height, and added a white border on the right of the left div. Also added rounded corners to more match your example (These won't work in ie 8 or less). I also took out the position: relative. You don't need it. Block level elements are set to position relative by default.
See it here: http://jsfiddle.net/ZSgLJ/
#left {
float: left;
width: 44%;
margin: 0;
padding: 0;
border-right: 1px solid white;
height:400px;
}
#right {
position: relative;
float: right;
width: 49%;
margin: 0;
padding: 0;
height:400px;
}
#blue_box {
background-color:blue;
border-radius: 10px;
-moz-border-radius:10px;
-webkit-border-radius: 10px;
width: 45%;
min-width: 400px;
max-width: 600px;
padding: 2%;
float: right;
}
It's a reference to the current object, it's most commonly used in object oriented code.
Example:
<?php
class Person {
public $name;
function __construct( $name ) {
$this->name = $name;
}
};
$jack = new Person('Jack');
echo $jack->name;
This stores the 'Jack' string as a property of the object created.
resourcesloader.class.getClass()
Can be broken down to:
Class<resourcesloader> clazz = resourceloader.class;
Class<Class> classClass = clazz.getClass();
Which means you're trying to load the resource using a bootstrap class.
Instead you probably want something like:
resourcesloader.class.getResource("repository/SSL-Key/cert.jks").toString()
If only javac warned about calling static methods on non-static contexts...
After downloading all the libraries said by ezaoutis, the error message on my windows 10 persisted, reading the wampserver3.1.3 installation requirements, there was a verification tool called check_vcredist.exe , i ran it and it show me all the missing libraries and it's download links, so i finally could install it succesfully.
Centered and middled content ?
Do it this way :
<table style="width:100%">
<tr>
<td valign="middle" align="center">Table once ruled centering</td>
</tr>
</table>
Ha, let me guess .. you want DIVs ..
just make your first outter DIV behave like a table-cell then style it with vertical align:middle;
<div>
<p>I want this paragraph to be at the center, but I can't.</p>
</div>
div {
width:500px;
height:100px;
background-color:aqua;
text-align:center;
/* there it is */
display:table-cell;
vertical-align:middle;
}
The basic syntax of initializing pointer that points to multidimentional array is
type (*pointer)[1st dimension size][2nd dimension size][..] = &array_name
The the basic syntax for calling it is
(*pointer_name)[1st index][2nd index][...]
Here is a example:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main() {
// The multidimentional array...
char balance[5][100] = {
"Subham",
"Messi"
};
char (*p)[5][100] = &balance; // Pointer initialization...
printf("%s\n",(*p)[0]); // Calling...
printf("%s\n",(*p)[1]); // Calling...
return 0;
}
Output is:
Subham
Messi
It worked...
Notice that you're using Observable#map to convert the raw Response object your base Observable emits to a parsed representation of the JSON response.
If I understood you correctly, you want to map again. But this time, converting that raw JSON to instances of your Model. So you would do something like:
http.get('api/people.json')
.map(res => res.json())
.map(peopleData => peopleData.map(personData => new Person(personData)))
So, you started with an Observable that emits a Response object, turned that into an observable that emits an object of the parsed JSON of that response, and then turned that into yet another observable that turned that raw JSON into an array of your models.
Since the encoding that turns "the Family" into "t?? T???ly" is effectively random and not following any algorithm that can be explained by the information of the Unicode codepoints involved, there's no general way to solve this algorithmically.
You will need to build the mapping of Unicode characters into latin characters which they resemble. You could probably do this with some smart machine learning on the actual glyphs representing the Unicode codepoints. But I think the effort for this would be greater than manually building that mapping. Especially if you have a good amount of examples from which you can build your mapping.
To clarify: a few of the substitutions can actually be solved via the Unicode data (as the other answers demonstrate), but some letters simply have no reasonable association with the latin characters which they resemble.
Examples:
This boils down to two distinct steps:
which()data.frame by excluding the indices from the previous step.Here is an example:
R> set.seed(42)
R> DF <- data.frame(sub=rep(1:4, each=4), day=sample(1:4, 16, replace=TRUE))
R> DF
sub day
1 1 4
2 1 4
3 1 2
4 1 4
5 2 3
6 2 3
7 2 3
8 2 1
9 3 3
10 3 3
11 3 2
12 3 3
13 4 4
14 4 2
15 4 2
16 4 4
R> ind <- which(with( DF, sub==2 & day==3 ))
R> ind
[1] 5 6 7
R> DF <- DF[ -ind, ]
R> table(DF)
day
sub 1 2 3 4
1 0 1 0 3
2 1 0 0 0
3 0 1 3 0
4 0 2 0 2
R>
And we see that sub==2 has only one entry remaining with day==1.
Edit The compound condition can be done with an 'or' as follows:
ind <- which(with( DF, (sub==1 & day==2) | (sub=3 & day=4) ))
and here is a new full example
R> set.seed(1)
R> DF <- data.frame(sub=rep(1:4, each=5), day=sample(1:4, 20, replace=TRUE))
R> table(DF)
day
sub 1 2 3 4
1 1 2 1 1
2 1 0 2 2
3 2 1 1 1
4 0 2 1 2
R> ind <- which(with( DF, (sub==1 & day==2) | (sub==3 & day==4) ))
R> ind
[1] 1 2 15
R> DF <- DF[-ind, ]
R> table(DF)
day
sub 1 2 3 4
1 1 0 1 1
2 1 0 2 2
3 2 1 1 0

if you mean to opening all links on new tab, try to use this jquery
$(document).on('click', 'a', function(e){
e.preventDefault();
var url = $(this).attr('href');
window.open(url, '_blank');
});
For Nginx, the only thing that worked for me was adding this header:
add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';
Along with the Access-Control-Allow-Origin header:
add_header 'Access-Control-Allow-Origin' '*';
Then reloaded the nginx config and it worked great. Credit https://gist.github.com/algal/5480916.
As Get-Date returns a DateTime object you are able to compare them directly. An example:
(get-date 2010-01-02) -lt (get-date 2010-01-01)
will return false.
Maybe I'm misunderstanding your question, but the offset is supposed to give you two variables: a horizontal and a vertical. This defines the position of the element. So what you're looking for is:
$("#whatever").offset().left
and
$("#whatever").offset().top
If you need to know where the right boundary of your element is, then you should use:
$("#whatever").offset().left + $("#whatever").outerWidth()
These instructions are for XCode 6.4 (since I couldn't find the update for the recent versions even this was a bit outdated)
a) Part on the developers' website:
Sign in into: https://developer.apple.com/
Member Center
Certificates, Identifiers & Profiles
Certificates>All
Click "+" to add, and then follow the instructions. You will need to open "Keychain Access.app", there under "Keychain Access" menu > "Certificate Assistant>", choose "Request a Certificate From a Certificate Authority" etc.
b) XCode part:
After all, you need to go to XCode, and open XCode>Preferences..., choose your Apple ID > View Details... > click that rounded arrow to update as well as "+" to check for iOS Distribution or iOS Developer Signing Identities.
You will first need to update the local formulas by doing
brew update
and then upgrade the package by doing
brew upgrade formula-name
An example would be if i wanted to upgrade mongodb, i would do something like this, assuming mongodb was already installed :
brew update && brew upgrade mongodb && brew cleanup mongodb
Variables are declared and assigned without $ and without {}. You have to use
var=10
to assign. In order to read from the variable (in other words, 'expand' the variable), you must use $.
$var # use the variable
${var} # same as above
${var}bar # expand var, and append "bar" too
$varbar # same as ${varbar}, i.e expand a variable called varbar, if it exists.
This has confused me sometimes - in other languages we refer to the variable in the same way, regardless of whether it's on the left or right of an assignment. But shell-scripting is different, $var=10 doesn't do what you might think it does!
with open(fname) as f:
next(f)
for line in f:
#do something
git reset --hard origin/master
says: throw away all my staged and unstaged changes, forget everything on my current local branch and make it exactly the same as origin/master.
You probably wanted to ask this before you ran the command. The destructive nature is hinted at by using the same words as in "hard reset".

I was able to accomplish this by using bind(). I wanted to click a button in index.jsx, post some data to the server, evaluate the response, and redirect to success.jsx. Here's how I worked that out...
index.jsx:
import React, { Component } from "react"
import { postData } from "../../scripts/request"
class Main extends Component {
constructor(props) {
super(props)
this.handleClick = this.handleClick.bind(this)
this.postData = postData.bind(this)
}
handleClick() {
const data = {
"first_name": "Test",
"last_name": "Guy",
"email": "[email protected]"
}
this.postData("person", data)
}
render() {
return (
<div className="Main">
<button onClick={this.handleClick}>Test Post</button>
</div>
)
}
}
export default Main
request.js:
import { post } from "./fetch"
export const postData = function(url, data) {
// post is a fetch() in another script...
post(url, data)
.then((result) => {
if (result.status === "ok") {
this.props.history.push("/success")
}
})
}
success.jsx:
import React from "react"
const Success = () => {
return (
<div className="Success">
Hey cool, got it.
</div>
)
}
export default Success
So by binding this to postData in index.jsx, I was able to access this.props.history in request.js... then I can reuse this function in different components, just have to make sure I remember to include this.postData = postData.bind(this) in the constructor().
From my point of view,
This is how I would do it personally:
function copyFolderSync(from, to) {
fs.mkdirSync(to);
fs.readdirSync(from).forEach(element => {
if (fs.lstatSync(path.join(from, element)).isFile()) {
fs.copyFileSync(path.join(from, element), path.join(to, element));
} else {
copyFolderSync(path.join(from, element), path.join(to, element));
}
});
}
It works for folders and files.
I feel we had a related discussion earlier: How to upload preview image before upload through JavaScript
You mention the most commonly implemented, which is Adjacency List: https://blogs.msdn.microsoft.com/mvpawardprogram/2012/06/25/hierarchies-convert-adjacency-list-to-nested-sets
There are other models as well, including materialized path and nested sets: http://communities.bmc.com/communities/docs/DOC-9902
Joe Celko has written a book on this subject, which is a good reference from a general SQL perspective (it is mentioned in the nested set article link above).
Also, Itzik Ben-Gann has a good overview of the most common options in his book "Inside Microsoft SQL Server 2005: T-SQL Querying".
The main things to consider when choosing a model are:
1) Frequency of structure change - how frequently does the actual structure of the tree change. Some models provide better structure update characteristics. It is important to separate structure changes from other data changes however. For example, you may want to model a company's organizational chart. Some people will model this as an adjacency list, using the employee ID to link an employee to their supervisor. This is usually a sub-optimal approach. An approach that often works better is to model the org structure separate from employees themselves, and maintain the employee as an attribute of the structure. This way, when an employee leaves the company, the organizational structure itself does not need to be changes, just the association with the employee that left.
2) Is the tree write-heavy or read-heavy - some structures work very well when reading the structure, but incur additional overhead when writing to the structure.
3) What types of information do you need to obtain from the structure - some structures excel at providing certain kinds of information about the structure. Examples include finding a node and all its children, finding a node and all its parents, finding the count of child nodes meeting certain conditions, etc. You need to know what information will be needed from the structure to determine the structure that will best fit your needs.
Isn't the question essentially: can I write the following?
if (foo)
console.log(bar)
else
console.log(foo + bar)
the answer is, yes, the above will translate.
however, be wary of doing the following
if (foo)
if (bar)
console.log(foo)
else
console.log(bar)
else
console.log(foobar)
be sure to wrap ambiguous code in braces as the above will throw an exception (and similar permutations will produce undesired behaviour.)
You have to check unique identifier column and you have to give a diff value to that particular field if you give the same value it will not work. It enforces uniqueness of the key.

Simply add this to your java module's build.gradle. It'll create executable jar. It will include dependent libraries in archive.
jar {
manifest {
attributes "Main-Class": "com.company.application.Main"
}
from {
configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
}
This will result in [module_name]/build/libs/[module_name].jar file. I tested this with shell.
defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do
import alias from 'my-module';
Alternatively you can do
import {default as alias} from 'my-module';
but that's rather esoteric.
You can use find with the -prune option.
An example from man find:
cd /source-dir
find . -name .snapshot -prune -o \( \! -name *~ -print0 \)|
cpio -pmd0 /dest-dir
This command copies the contents of /source-dir to /dest-dir, but omits
files and directories named .snapshot (and anything in them). It also
omits files or directories whose name ends in ~, but not their con-
tents. The construct -prune -o \( ... -print0 \) is quite common. The
idea here is that the expression before -prune matches things which are
to be pruned. However, the -prune action itself returns true, so the
following -o ensures that the right hand side is evaluated only for
those directories which didn't get pruned (the contents of the pruned
directories are not even visited, so their contents are irrelevant).
The expression on the right hand side of the -o is in parentheses only
for clarity. It emphasises that the -print0 action takes place only
for things that didn't have -prune applied to them. Because the
default `and' condition between tests binds more tightly than -o, this
is the default anyway, but the parentheses help to show what is going
on.
This will do what you want. Fixed sides with 50px-width, and the content fills the remaining area.
<div style="width:100%;">
<div style="width: 50px; float: left;">Left Side</div>
<div style="width: 50px; float: right;">Right Side</div>
<div style="margin-left: 50px; margin-right: 50px;">Content Goes Here</div>
</div>
Another way of doing this, in code only, is to detect if the process is running as admin like in the answer by @NG.. And then open the application again and close the current one.
I use this code when an application only needs admin privileges when run under certain conditions, such as when installing itself as a service. So it doesn't need to run as admin all the time like the other answers force it too.
Note in the below code NeedsToRunAsAdmin is a method that detects if under current conditions admin privileges are required. If this returns false the code will not elevate itself. This is a major advantage of this approach over the others.
Although this code has the advantages stated above, it does need to re-launch itself as a new process which isn't always what you want.
private static void Main(string[] args)
{
if (NeedsToRunAsAdmin() && !IsRunAsAdmin())
{
ProcessStartInfo proc = new ProcessStartInfo();
proc.UseShellExecute = true;
proc.WorkingDirectory = Environment.CurrentDirectory;
proc.FileName = Assembly.GetEntryAssembly().CodeBase;
foreach (string arg in args)
{
proc.Arguments += String.Format("\"{0}\" ", arg);
}
proc.Verb = "runas";
try
{
Process.Start(proc);
}
catch
{
Console.WriteLine("This application requires elevated credentials in order to operate correctly!");
}
}
else
{
//Normal program logic...
}
}
private static bool IsRunAsAdmin()
{
WindowsIdentity id = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(id);
return principal.IsInRole(WindowsBuiltInRole.Administrator);
}
I'm facing this problem in a TYPO3 website, where all "Content Elements" are wrapped with something like:
<div id="c1234" class="contentElement">...</div>
and i changed the rendering so it renders like this:
<div id="c1234" class="anchor"></div>
<div class="contentElement">...</div>
And this CSS:
.anchor{
position: relative;
top: -50px;
}
The fixed topbar being 40px high, now the anchors work again and start 10px under the topbar.
Only drawback of this technique is you can no longer use :target.
In Chrome, For "Selenium IDE", I was also struggling that it doesn't pause. It will pause, if you give as below:
This will pause for 10 seconds.
Choice one! But the first is very simple. The last maybe util for file manipulation:
//Method 1 (I like this)
File.AppendAllLines(
"FileAppendAllLines.txt",
new string[] { "line1", "line2", "line3" });
//Method 2
File.AppendAllText(
"FileAppendAllText.txt",
"line1" + Environment.NewLine +
"line2" + Environment.NewLine +
"line3" + Environment.NewLine);
//Method 3
using (StreamWriter stream = File.AppendText("FileAppendText.txt"))
{
stream.WriteLine("line1");
stream.WriteLine("line2");
stream.WriteLine("line3");
}
//Method 4
using (StreamWriter stream = new StreamWriter("StreamWriter.txt", true))
{
stream.WriteLine("line1");
stream.WriteLine("line2");
stream.WriteLine("line3");
}
//Method 5
using (StreamWriter stream = new FileInfo("FileInfo.txt").AppendText())
{
stream.WriteLine("line1");
stream.WriteLine("line2");
stream.WriteLine("line3");
}

All other answers on this question didn't hit upon the key point.
Assume we have a table:
CREATE TABLE `table` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`value` int(10) unsigned NOT NULL,
PRIMARY KEY (`id`),
KEY `value` (`value`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
And have 10 rows with both id and value from 1 to 10:
INSERT INTO `table`(`id`, `value`) VALUES (1, 1),(2, 2),(3, 3),(4, 4),(5, 5),(6, 6),(7, 7),(8, 8),(9, 9),(10, 10);
Try the following 2 queries:
SELECT `value` v FROM `table` WHERE `value`>5; -- Get 5 rows
SELECT `value` v FROM `table` HAVING `value`>5; -- Get 5 rows
You will get exactly the same results, you can see the HAVING clause can work without GROUP BY clause.
Here's the difference:
SELECT `value` v FROM `table` WHERE `v`>5;
Error #1054 - Unknown column 'v' in 'where clause'
SELECT `value` v FROM `table` HAVING `v`>5; -- Get 5 rows
WHERE clause allows a condition to use any table column, but it cannot use aliases or aggregate functions. HAVING clause allows a condition to use a selected (!) column, alias or an aggregate function.
This is because WHERE clause filters data before select, but HAVING clause filters resulting data after select.
So put the conditions in WHERE clause will be more efficient if you have many many rows in a table.
Try EXPLAIN to see the key difference:
EXPLAIN SELECT `value` v FROM `table` WHERE `value`>5;
+----+-------------+-------+-------+---------------+-------+---------+------+------+--------------------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+-------+-------+---------------+-------+---------+------+------+--------------------------+
| 1 | SIMPLE | table | range | value | value | 4 | NULL | 5 | Using where; Using index |
+----+-------------+-------+-------+---------------+-------+---------+------+------+--------------------------+
EXPLAIN SELECT `value` v FROM `table` having `value`>5;
+----+-------------+-------+-------+---------------+-------+---------+------+------+-------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+-------+-------+---------------+-------+---------+------+------+-------------+
| 1 | SIMPLE | table | index | NULL | value | 4 | NULL | 10 | Using index |
+----+-------------+-------+-------+---------------+-------+---------+------+------+-------------+
You can see either WHERE or HAVING uses index, but the rows are different.
I had this issue when I was trying to reinstall Android Studio through its wizard. I already had a "tools" folder though.
In my case, while the "tools" directory already existed, it will deliver the "sdk tools directory is missing" error for its subfolders also. Somehow my sdk folder only had a libs subdirectory.
When I pasted in sdk/ant, sdk/apps, sdk/proguard, sdk/qemu, sdk/support, and sdk/templates the wizard was finally happy with this configuration and went to download some more files.
SQL injection can be a tricky problem but there are ways around it. Your risk is reduced your risk simply by using an ORM like Linq2Entities, Linq2SQL, NHibrenate. However you can have SQL injection problems even with them.
The main thing with SQL injection is user controlled input (as is with XSS). In the most simple example if you have a login form (I hope you never have one that just does this) that takes a username and password.
SELECT * FROM Users WHERE Username = '" + username + "' AND password = '" + password + "'"
If a user were to input the following for the username Admin' -- the SQL Statement would look like this when executing against the database.
SELECT * FROM Users WHERE Username = 'Admin' --' AND password = ''
In this simple case using a paramaterized query (which is what an ORM does) would remove your risk. You also have a the issue of a lesser known SQL injection attack vector and that's with stored procedures. In this case even if you use a paramaterized query or an ORM you would still have a SQL injection problem. Stored procedures can contain execute commands, and those commands themselves may be suceptable to SQL injection attacks.
CREATE PROCEDURE SP_GetLogin @username varchar(100), @password varchar(100) AS
DECLARE @sql nvarchar(4000)
SELECT @sql = ' SELECT * FROM users' +
' FROM Product Where username = ''' + @username + ''' AND password = '''+@password+''''
EXECUTE sp_executesql @sql
So this example would have the same SQL injection problem as the previous one even if you use paramaterized queries or an ORM. And although the example seems silly you'd be surprised as to how often something like this is written.
My recommendations would be to use an ORM to immediately reduce your chances of having a SQL injection problem, and then learn to spot code and stored procedures which can have the problem and work to fix them. I don't recommend using ADO.NET (SqlClient, SqlCommand etc...) directly unless you have to, not because it's somehow not safe to use it with parameters but because it's that much easier to get lazy and just start writing a SQL query using strings and just ignoring the parameters. ORMS do a great job of forcing you to use parameters because it's just what they do.
Next Visit the OWASP site on SQL injection https://www.owasp.org/index.php/SQL_Injection and use the SQL injection cheat sheet to make sure you can spot and take out any issues that will arise in your code. https://www.owasp.org/index.php/SQL_Injection_Prevention_Cheat_Sheet finally I would say put in place a good code review between you and other developers at your company where you can review each others code for things like SQL injection and XSS. A lot of times programmers miss this stuff because they're trying to rush out some feature and don't spend too much time on reviewing their code.

Linux: Remove redundant paths from $PATH variable
Linux From Scratch has this function in /etc/profile
# Functions to help us manage paths. Second argument is the name of the
# path variable to be modified (default: PATH)
pathremove () {
local IFS=':'
local NEWPATH
local DIR
local PATHVARIABLE=${2:-PATH}
for DIR in ${!PATHVARIABLE} ; do
if [ "$DIR" != "$1" ] ; then
NEWPATH=${NEWPATH:+$NEWPATH:}$DIR
fi
done
export $PATHVARIABLE="$NEWPATH"
}
This is intended to be used with these functions for adding to the path, so that you don't do it redundantly:
pathprepend () {
pathremove $1 $2
local PATHVARIABLE=${2:-PATH}
export $PATHVARIABLE="$1${!PATHVARIABLE:+:${!PATHVARIABLE}}"
}
pathappend () {
pathremove $1 $2
local PATHVARIABLE=${2:-PATH}
export $PATHVARIABLE="${!PATHVARIABLE:+${!PATHVARIABLE}:}$1"
}
Simple usage is to just give pathremove the directory path to remove - but keep in mind that it has to match exactly:
$ pathremove /home/username/anaconda3/bin
This will remove each instance of that directory from your path.
If you want the directory in your path, but without the redundancies, you could just use one of the other functions, e.g. - for your specific case:
$ pathprepend /usr/local/sbin
$ pathappend /usr/local/bin
$ pathappend /usr/sbin
$ pathappend /usr/bin
$ pathappend /sbin
$ pathappend /bin
$ pathappend /usr/games
But, unless readability is the concern, at this point you're better off just doing:
$ export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
I would presume the above to work in sh, dash, and bash at least. I would be surprised to learn it doesn't work in csh, fish', orksh`. I doubt it would work in Windows command shell or Powershell.
If you have Python, the following sort of command should do what is directly asked (that is, remove redundant paths):
$ PATH=$( python -c "
import os
path = os.environ['PATH'].split(':')
print(':'.join(sorted(set(path), key=path.index)))
" )
A one-liner (to sidestep multiline issues):
$ PATH=$( python -c "import os; path = os.environ['PATH'].split(':'); print(':'.join(sorted(set(path), key=path.index)))" )
The above removes later redundant paths. To remove earlier redundant paths, use a reversed list's index and reverse it again:
$ PATH=$( python -c "
import os
path = os.environ['PATH'].split(':')[::-1]
print(':'.join(sorted(set(path), key=path.index, reverse=True)))
" )

if you include a returnStatus: true property, then the shell return is ignored.
Note first that your question shows a bit of misunderstanding. origin/HEAD represents the default branch on the remote, i.e. the HEAD that's in that remote repository you're calling origin. When you switch branches in your repo, you're not affecting that. The same is true for remote branches; you might have master and origin/master in your repo, where origin/master represents a local copy of the master branch in the remote repository.
origin's HEAD will only change if you or someone else actually changes it in the remote repository, which should basically never happen - you want the default branch a public repo to stay constant, on the stable branch (probably master). origin/HEAD is a local ref representing a local copy of the HEAD in the remote repository. (Its full name is refs/remotes/origin/HEAD.)
I think the above answers what you actually wanted to know, but to go ahead and answer the question you explicitly asked... origin/HEAD is set automatically when you clone a repository, and that's about it. Bizarrely, that it's not set by commands like git remote update - I believe the only way it will change is if you manually change it. (By change I mean point to a different branch; obviously the commit it points to changes if that branch changes, which might happen on fetch/pull/remote update.)
Edit: The problem discussed below was corrected in Git 1.8.4.3; see this update.
There is a tiny caveat, though. HEAD is a symbolic ref, pointing to a branch instead of directly to a commit, but the git remote transfer protocols only report commits for refs. So Git knows the SHA1 of the commit pointed to by HEAD and all other refs; it then has to deduce the value of HEAD by finding a branch that points to the same commit. This means that if two branches happen to point there, it's ambiguous. (I believe it picks master if possible, then falls back to first alphabetically.) You'll see this reported in the output of git remote show origin:
$ git remote show origin
* remote origin
Fetch URL: ...
Push URL: ...
HEAD branch (remote HEAD is ambiguous, may be one of the following):
foo
master
Oddly, although the notion of HEAD printed this way will change if things change on the remote (e.g. if foo is removed), it doesn't actually update refs/remotes/origin/HEAD. This can lead to really odd situations. Say that in the above example origin/HEAD actually pointed to foo, and origin's foo branch was then removed. We can then do this:
$ git remote show origin
...
HEAD branch: master
$ git symbolic-ref refs/remotes/origin/HEAD
refs/remotes/origin/foo
$ git remote update --prune origin
Fetching origin
x [deleted] (none) -> origin/foo
(refs/remotes/origin/HEAD has become dangling)
So even though remote show knows HEAD is master, it doesn't update anything. The stale foo branch is correctly pruned, and HEAD becomes dangling (pointing to a nonexistent branch), and it still doesn't update it to point to master. If you want to fix this, use git remote set-head origin -a, which automatically determines origin's HEAD as above, and then actually sets origin/HEAD to point to the appropriate remote branch.

Here first one "ORCL" is database name,may be your system "XE" and other what was given on oracle downloading time.
Solved, at least at the point of the question.
I searched in the web before asking, an there were no conclusive solution, the reason why this error is: lib1.so and lib2.so are not OK, very probably where not compiled for a 64 PC, but for a 32 bits machine otherwise lib3.so is a 64 bits lib. At least that is my hipothesis.
VERY unfortunately ldconfig doesn't give a clean error message informing that it could not load the library, it only pumps:
ldconfig: /folder_where_the_wicked_lib_is/ is not a symbolic link
I solved this when I removed the libs not found by ldd over the binary. Now it's easier that I know where lies the problem.
My ld version: GNU ld version 2.20.51, and I don't know if a most recent version has a better message for its users.
Thanks.

tl;dr:
concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.
The warning is new in pandas 0.23.0:
In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned,
link.
More information from linked very old github issue, comment by smcinerney :
When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.
This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.
After some time the parameter sort was implemented in pandas.concat and DataFrame.append:
sort : boolean, default None
Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.
Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.
This has no effect when join='inner', which already preserves the order of the non-concatenation axis.
So if both DataFrames have the same columns in the same order, there is no warning and no sorting:
df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])
print (pd.concat([df1, df2]))
a b
0 1 0
1 2 8
0 4 7
1 5 3
df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])
print (pd.concat([df1, df2]))
b a
0 0 1
1 8 2
0 7 4
1 3 5
But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):
df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])
print (pd.concat([df1, df2]))
FutureWarning: Sorting because non-concatenation axis is not aligned.
a b
0 1 0
1 2 8
0 4 7
1 5 3
print (pd.concat([df1, df2], sort=True))
a b
0 1 0
1 2 8
0 4 7
1 5 3
print (pd.concat([df1, df2], sort=False))
b a
0 0 1
1 8 2
0 7 4
1 3 5
If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.
Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:
df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]},
columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]},
columns=['c','b','a','d'])
print (pd.concat([df1, df2]))

if you want to use HEX instead of RGBA, just drag a new empty .swift and add below mentioned code:
import UIKit
extension UIColor {
convenience init(rgba: String) {
var red: CGFloat = 0.0
var green: CGFloat = 0.0
var blue: CGFloat = 0.0
var alpha: CGFloat = 1.0
if rgba.hasPrefix("#") {
let index = advance(rgba.startIndex, 1)
let hex = rgba.substringFromIndex(index)
let scanner = NSScanner(string: hex)
var hexValue: CUnsignedLongLong = 0
if scanner.scanHexLongLong(&hexValue) {
switch (count(hex)) {
case 3:
red = CGFloat((hexValue & 0xF00) >> 8) / 15.0
green = CGFloat((hexValue & 0x0F0) >> 4) / 15.0
blue = CGFloat(hexValue & 0x00F) / 15.0
case 4:
red = CGFloat((hexValue & 0xF000) >> 12) / 15.0
green = CGFloat((hexValue & 0x0F00) >> 8) / 15.0
blue = CGFloat((hexValue & 0x00F0) >> 4) / 15.0
alpha = CGFloat(hexValue & 0x000F) / 15.0
case 6:
red = CGFloat((hexValue & 0xFF0000) >> 16) / 255.0
green = CGFloat((hexValue & 0x00FF00) >> 8) / 255.0
blue = CGFloat(hexValue & 0x0000FF) / 255.0
case 8:
red = CGFloat((hexValue & 0xFF000000) >> 24) / 255.0
green = CGFloat((hexValue & 0x00FF0000) >> 16) / 255.0
blue = CGFloat((hexValue & 0x0000FF00) >> 8) / 255.0
alpha = CGFloat(hexValue & 0x000000FF) / 255.0
default:
print("Invalid RGB string, number of characters after '#' should be either 3, 4, 6 or 8")
}
} else {
println("Scan hex error")
}
} else {
print("Invalid RGB string, missing '#' as prefix")
}
self.init(red:red, green:green, blue:blue, alpha:alpha)
}
}
similarly, drag another empty .swift file and add below mentioned code:
class Colors {
let colorTop = UIColor(rgba: "##8968CD").CGColor
let colorBottom = UIColor(rgba: "#5D478B").CGColor
let gl: CAGradientLayer
init() {
gl = CAGradientLayer()
gl.colors = [ colorTop, colorBottom]
gl.locations = [ 0.0, 1.0]
}
}
after that in view controller, under class instantiate your 'Color' class like this:
let colors = Colors()
add a new function:
func refresh() {
view.backgroundColor = UIColor.clearColor()
var backgroundLayer = colors.gl
backgroundLayer.frame = view.frame
view.layer.insertSublayer(backgroundLayer, atIndex: 0)
}
state that function in viewDidLoad:
refresh()
you're done :)) using HEX is way too easy if compared to RGBA. :D
Console console = System.console();
String username = console.readLine("Username: ");
char[] password = console.readPassword("Password: ");
If your test case runner returns a non-zero code for failed tests, you can simply write:
test_handler test_case_x; test_result=$?
if ((test_result != 0)); then
printf '%s\n' "Test case x failed" >&2 # write error message to stderr
exit 1 # or exit $test_result
fi
Or even shorter:
if ! test_handler test_case_x; then
printf '%s\n' "Test case x failed" >&2
exit 1
fi
Or the shortest:
test_handler test_case_x || { printf '%s\n' "Test case x failed" >&2; exit 1; }
To exit with test_handler's exit code:
test_handler test_case_x || { ec=$?; printf '%s\n' "Test case x failed" >&2; exit $ec; }
If you want to take a more comprehensive approach, you can have an error handler:
exit_if_error() {
local exit_code=$1
shift
[[ $exit_code ]] && # do nothing if no error code passed
((exit_code != 0)) && { # do nothing if error code is 0
printf 'ERROR: %s\n' "$@" >&2 # we can use better logging here
exit "$exit_code" # we could also check to make sure
# error code is numeric when passed
}
}
then invoke it after running your test case:
run_test_case test_case_x
exit_if_error $? "Test case x failed"
or
run_test_case test_case_x || exit_if_error $? "Test case x failed"
The advantages of having an error handler like exit_if_error are:
if blocks that test exit codes for errorsHere is a complete implementation of error handling and logging:

This allows you to use the Python 3.0 style print function without having to hand-edit all occurrences of print :)
The animate(..) function' signature is:
.animate( properties, options );
And it says the following about the parameter properties:
properties A map of CSS properties that the animation will move toward.
text is not a CSS property, this is why the function isn't working as you expected.
Do you want to fade the text out? Do you want to move it? I might be able to provide an alternative.

After searching around a bit, the best solution in my opinion makes use of hudson.model.EnvironmentContributingAction.
import hudson.model.EnvironmentContributingAction
import hudson.model.AbstractBuild
import hudson.EnvVars
class BuildVariableInjector {
def build
def out
def BuildVariableInjector(build, out) {
this.build = build
this.out = out
}
def addBuildEnvironmentVariable(key, value) {
def action = new VariableInjectionAction(key, value)
build.addAction(action)
//Must call this for action to be added
build.getEnvironment()
}
class VariableInjectionAction implements EnvironmentContributingAction {
private String key
private String value
public VariableInjectionAction(String key, String value) {
this.key = key
this.value = value
}
public void buildEnvVars(AbstractBuild build, EnvVars envVars) {
if (envVars != null && key != null && value != null) {
envVars.put(key, value);
}
}
public String getDisplayName() {
return "VariableInjectionAction";
}
public String getIconFileName() {
return null;
}
public String getUrlName() {
return null;
}
}
}
I use this class in a system groovy script (using the groovy plugin) within a job.
import hudson.model.*
import java.io.File;
import jenkins.model.Jenkins;
def jenkinsRootDir = build.getEnvVars()["JENKINS_HOME"];
def parent = getClass().getClassLoader()
def loader = new GroovyClassLoader(parent)
def buildVariableInjector = loader.parseClass(new File(jenkinsRootDir + "/userContent/GroovyScripts/BuildVariableInjector.groovy")).newInstance(build, getBinding().out)
def projectBranchDependencies = []
//Some logic to set projectBranchDependencies variable
buildVariableInjector.addBuildEnvironmentVariable("projectBranchDependencies", projectBranchDependencies.join(","));
You can then access the projectBranchDependencies variable at any other point in your build, in my case, from an ANT script.
Note: I borrowed / modified the ideas for parts of this implementation from a blog post, but at the time of this posting I was unable to locate the original source in order to give due credit.
I ran into this when trying to run spring boot from the command line...
mvn spring-boot:run
I accidentally mis-typed the command as...

Followed Stephen's advice and tried to debug the code and whoa! it worked. The answer lies in the debug message itself.
Will attempt to recover by breaking constraint
NSLayoutConstraint:0x191f0920 H:[MPKnockoutButton:0x17a876b0]-(34)-[MPDetailSlider:0x17a8bc50](LTR)>
The line above tells you that the runtime worked by removing this constraint. May be you don't need Horizontal Spacing on your button (MPKnockoutButton). Once you clear this constraint, it won't complain at runtime & you would get the desired behaviour.
A possible solution using sscanf() and scan sets:
const char* s = "ab234cid*(s349*(20kd";
int i1, i2, i3;
if (3 == sscanf(s,
"%*[^0123456789]%d%*[^0123456789]%d%*[^0123456789]%d",
&i1,
&i2,
&i3))
{
printf("%d %d %d\n", i1, i2, i3);
}
where %*[^0123456789] means ignore input until a digit is found. See demo at http://ideone.com/2hB4UW .
Or, if the number of numbers is unknown you can use %n specifier to record the last position read in the buffer:
const char* s = "ab234cid*(s349*(20kd";
int total_n = 0;
int n;
int i;
while (1 == sscanf(s + total_n, "%*[^0123456789]%d%n", &i, &n))
{
total_n += n;
printf("%d\n", i);
}
<script>
var deg = 0
function rotate(id)
{
deg = deg+45;
var txt = 'rotate('+deg+'deg)';
$('#'+id).css('-webkit-transform',txt);
}
</script>
What I do is something very easy... declare a global variable at the start... and then increment the variable however much I like, and use .css of jquery to increment.
The below css works for both Chrome and Firefox
input[type=number]::-webkit-outer-spin-button,
input[type=number]::-webkit-inner-spin-button {
-webkit-appearance: none;
margin: 0;
}
input[type=number] {
-moz-appearance:textfield;
}
In Swift3:
let fileUrl = Foundation.URL(string: filePath)
I am currently using these functions:
// trim from left
inline std::string& ltrim(std::string& s, const char* t = " \t\n\r\f\v")
{
s.erase(0, s.find_first_not_of(t));
return s;
}
// trim from right
inline std::string& rtrim(std::string& s, const char* t = " \t\n\r\f\v")
{
s.erase(s.find_last_not_of(t) + 1);
return s;
}
// trim from left & right
inline std::string& trim(std::string& s, const char* t = " \t\n\r\f\v")
{
return ltrim(rtrim(s, t), t);
}
// copying versions
inline std::string ltrim_copy(std::string s, const char* t = " \t\n\r\f\v")
{
return ltrim(s, t);
}
inline std::string rtrim_copy(std::string s, const char* t = " \t\n\r\f\v")
{
return rtrim(s, t);
}
inline std::string trim_copy(std::string s, const char* t = " \t\n\r\f\v")
{
return trim(s, t);
}
Why not
DisplayMetrics displaymetrics = getResources().getDisplayMetrics();
then use
displayMetrics.widthPixels (heightPixels)
If you know your database has been updated and you want to just refresh your ViewController (which was my case). I didn't find another solution but what I did was when my database updated, I called:
[self viewDidLoad];
again, and it worked. Remember if you override other viewWillAppear or loadView then call them too in same order. like.
[self viewDidLoad]; [self viewWillAppear:YES];
I think there should be a more specific solution like refresh button in browser.
Use Counter
>>> from collections import Counter
>>> MyList = ["a", "b", "a", "c", "c", "a", "c"]
>>> c = Counter(MyList)
>>> c
Counter({'a': 3, 'c': 3, 'b': 1})
Did you check the string concatenation function? Something like:
update table_c set column_a = column_b || column_c
should work. More here
