Use Python 2.7, is has more 3rd party libs at the moment. (Edit: see below).
I recommend you using the stdlib module urllib2
, it will allow you to comfortably get web resources.
Example:
import urllib2
response = urllib2.urlopen("http://google.de")
page_source = response.read()
For parsing the code, have a look at BeautifulSoup
.
BTW: what exactly do you want to do:
Just for background, I need to download a page and replace any img with ones I have
Edit: It's 2014 now, most of the important libraries have been ported, and you should definitely use Python 3 if you can. python-requests
is a very nice high-level library which is easier to use than urllib2
.
The AutoPostBack property is used to set or return whether or not an automatic post back occurs when the user presses "ENTER" or "TAB" in the TextBox control.
If this property is set to TRUE the automatic post back is enabled, otherwise FALSE. Default is FALSE.
<!-- Server port-->
server.port=8080

I ran into the same issue. I was able to get my results to a CSV using the following solution:
var test = parseInt($("#testid").val(), 10);
You have to tell it you want the value
of the input you are targeting.
And also, always provide the second argument (radix) to parseInt
. It tries to be too clever and autodetect it if not provided and can lead to unexpected results.
Providing 10
assumes you are wanting a base 10 number.
You can try as below :
declare @list varchar(MAX), @i int
select @i=0, @list ='4,7,12,22,19,'
while( @i < LEN(@list))
begin
declare @item varchar(MAX)
SELECT @item = SUBSTRING(@list, @i,CHARINDEX(',',@list,@i)-@i)
select @item
--do your stuff here with @item
exec p_MyInnerProcedure @item
set @i = CHARINDEX(',',@list,@i)+1
if(@i = 0) set @i = LEN(@list)
end
From the Web Designer’s Guide to PNG Image Format
PNG-8 and PNG-24
There are two PNG formats: PNG-8 and PNG-24. The numbers are shorthand for saying "8-bit PNG" or "24-bit PNG." Not to get too much into technicalities — because as a web designer, you probably don’t care — 8-bit PNGs mean that the image is 8 bits per pixel, while 24-bit PNGs mean 24 bits per pixel.
To sum up the difference in plain English: Let’s just say PNG-24 can handle a lot more color and is good for complex images with lots of color such as photographs (just like JPEG), while PNG-8 is more optimized for things with simple colors, such as logos and user interface elements like icons and buttons.
Another difference is that PNG-24 natively supports alpha transparency, which is good for transparent backgrounds. This difference is not 100% true because Adobe products’ Save for Web command allows PNG-8 with alpha transparency.

Either of the following SQL will return all schema in Oracle DB.
select owner FROM all_tables group by owner;
select distinct owner FROM all_tables;
the answers above were confusing to me. Here is what i did:
the first field "Asset type" must be launcher icons. browse to the file you want as icon, select it and android studio will show you in the same window what it will look like under different resolutions.
choose a different name for it, click next. Now the icon set for all those hdpi, xhdpi, mdpi will be in corresponding mipmap folders
finally, most importantly go to your manifest file and change "android:icon" to the name of your new icon image.
The ECMAscript standard does not specify which sort algorithm is to be used. Indeed, different browsers feature different sort algorithms. For example, Mozilla/Firefox's sort() is not stable (in the sorting sense of the word) when sorting a map. IE's sort() is stable.
!=
For example,
if ("apple" != "orange")
// true, the string "apple" is not equal to the string "orange"
Means not. See also the logical operators list. Also, when you see triple characters, it's a type sensitive comparison. (e.g. if (1 === '1')
[not equal])
Does this work?
float flt = 145.664454;

IIRC the server VM does more hotspot optimizations at startup so it runs faster but takes a little longer to start and uses more memory. The client VM defers most of the optimization to allow faster startup.

I had the report html output trouble on report retrieving 32000 lines. The query ran fast but the output into web browser was very slow. In my case I had to activate “Interactive Paging” to allow user to see first page and be able to generate Excel file. The pros of this solution is that first page appears fast and user can generate export to Excel or PDF, the cons is that user can scroll only current page. If user wants to see more content he\she must use navigation buttons above the grid. In my case user accepted this behavior because the export to Excel was more important.
To activate “Interactive Paging” you must click on the free area in the report pane and change property “InteractiveSize”\ “Height” on the report level in Properties pane. Set this property to different from 0. I set to 8.5 inches in my case. Also ensure that you unchecked “Keep together on one page if possible” property on the Tablix level (right click on the Tablix, then “Tablix Properties”, then “General”\ “Page Break Options”).
I did it like this, a variation on Vadims code but to me a bit more readable:
' Returns TRUE if item is already contained in collection, otherwise FALSE
Public Function Contains(col As Collection, item As String) As Boolean
Dim i As Integer
For i = 1 To col.Count
If col.item(i) = item Then
Contains = True
Exit Function
End If
Next i
Contains = False
End Function
I came to this page looking for a way of getting my own ip address not the one of the remote machine connecting to me.
This will not work for a windows machine.
But in case someone searches for what I was looking for:
#! /usr/bin/php
<?php
$my_current_ip=exec("ifconfig | grep -Eo 'inet (addr:)?([0-9]*\.){3}[0-9]*' | grep -Eo '([0-9]*\.){3}[0-9]*' | grep -v '127.0.0.1'");
echo $my_current_ip;
(Shamelessly adapted from How to I get the primary IP address of the local machine on Linux and OS X?)
If you don't want to loop, there's no way to do it with Arrays. You should use a Set instead.
require 'set'
s = Set.new
100.times{|i| s << "foo#{i}"}
s.include?("foo99")
=> true
[1,2,3,4,5,6,7,8].to_set.include?(4)
=> true
Sets work internally like Hashes, so Ruby doesn't need to loop through the collection to find items, since as the name implies, it generates hashes of the keys and creates a memory map so that each hash points to a certain point in memory. The previous example done with a Hash:
fake_array = {}
100.times{|i| fake_array["foo#{i}"] = 1}
fake_array.has_key?("foo99")
=> true
The downside is that Sets and Hash keys can only include unique items and if you add a lot of items, Ruby will have to rehash the whole thing after certain number of items to build a new map that suits a larger keyspace. For more about this, I recommend you watch "MountainWest RubyConf 2014 - Big O in a Homemade Hash by Nathan Long".
Here's a benchmark:
require 'benchmark'
require 'set'
array = []
set = Set.new
10_000.times do |i|
array << "foo#{i}"
set << "foo#{i}"
end
Benchmark.bm do |x|
x.report("array") { 10_000.times { array.include?("foo9999") } }
x.report("set ") { 10_000.times { set.include?("foo9999") } }
end
And the results:
user system total real
array 7.020000 0.000000 7.020000 ( 7.031525)
set 0.010000 0.000000 0.010000 ( 0.004816)
This line:
[self dismissViewControllerAnimated:YES completion:nil];
isn't sending a message to itself, it's actually sending a message to its presenting VC, asking it to do the dismissing. When you present a VC, you create a relationship between the presenting VC and the presented one. So you should not destroy the presenting VC while it is presenting (the presented VC can't send that dismiss message back…). As you're not really taking account of it you are leaving the app in a confused state. See my answer Dismissing a Presented View Controller in which I recommend this method is more clearly written:
[self.presentingViewController dismissViewControllerAnimated:YES completion:nil];
In your case, you need to ensure that all of the controlling is done in mainVC
. You should use a delegate to send the correct message back to MainViewController from ViewController1, so that mainVC can dismiss VC1 and then present VC2.
In VC2 VC1 add a protocol in your .h file above the @interface:
@protocol ViewController1Protocol <NSObject>
- (void)dismissAndPresentVC2;
@end
and lower down in the same file in the @interface section declare a property to hold the delegate pointer:
@property (nonatomic,weak) id <ViewController1Protocol> delegate;
In the VC1 .m file, the dismiss button method should call the delegate method
- (IBAction)buttonPressedFromVC1:(UIButton *)sender {
[self.delegate dissmissAndPresentVC2]
}
Now in mainVC, set it as VC1's delegate when creating VC1:
- (IBAction)present1:(id)sender {
ViewController1* vc = [[ViewController1 alloc] initWithNibName:@"ViewController1" bundle:nil];
vc.delegate = self;
[self present:vc];
}
and implement the delegate method:
- (void)dismissAndPresent2 {
[self dismissViewControllerAnimated:NO completion:^{
[self present2:nil];
}];
}
present2:
can be the same method as your VC2Pressed:
button IBAction method. Note that it is called from the completion block to ensure that VC2 is not presented until VC1 is fully dismissed.
You are now moving from VC1->VCMain->VC2 so you will probably want only one of the transitions to be animated.
update
In your comments you express surprise at the complexity required to achieve a seemingly simple thing. I assure you, this delegation pattern is so central to much of Objective-C and Cocoa, and this example is about the most simple you can get, that you really should make the effort to get comfortable with it.
In Apple's View Controller Programming Guide they have this to say:
Dismissing a Presented View Controller
When it comes time to dismiss a presented view controller, the preferred approach is to let the presenting view controller dismiss it. In other words, whenever possible, the same view controller that presented the view controller should also take responsibility for dismissing it. Although there are several techniques for notifying the presenting view controller that its presented view controller should be dismissed, the preferred technique is delegation. For more information, see “Using Delegation to Communicate with Other Controllers.”
If you really think through what you want to achieve, and how you are going about it, you will realise that messaging your MainViewController to do all of the work is the only logical way out given that you don't want to use a NavigationController. If you do use a NavController, in effect you are 'delegating', even if not explicitly, to the navController to do all of the work. There needs to be some object that keeps a central track of what's going on with your VC navigation, and you need some method of communicating with it, whatever you do.
In practice Apple's advice is a little extreme... in normal cases, you don't need to make a dedicated delegate and method, you can rely on [self presentingViewController] dismissViewControllerAnimated:
- it's when in cases like yours that you want your dismissing to have other effects on remote objects that you need to take care.
Here is something you could imagine to work without all the delegate hassle...
- (IBAction)dismiss:(id)sender {
[[self presentingViewController] dismissViewControllerAnimated:YES
completion:^{
[self.presentingViewController performSelector:@selector(presentVC2:)
withObject:nil];
}];
}
After asking the presenting controller to dismiss us, we have a completion block which calls a method in the presentingViewController to invoke VC2. No delegate needed. (A big selling point of blocks is that they reduce the need for delegates in these circumstances). However in this case there are a few things getting in the way...
present2
- you can end up with difficult-to-debug errors or crashes. Delegates help you to avoid this.So please... take the time to learn delegation!
update2
In your comment you have managed to make it work by using this in VC2's dismiss button handler:
[self.view.window.rootViewController dismissViewControllerAnimated:YES completion:nil];
This is certainly much simpler, but it leaves you with a number of issues.
Tight coupling
You are hard-wiring your viewController structure together. For example, if you were to insert a new viewController before mainVC, your required behaviour would break (you would navigate to the prior one). In VC1 you have also had to #import VC2. Therefore you have quite a lot of inter-dependencies, which breaks OOP/MVC objectives.
Using delegates, neither VC1 nor VC2 need to know anything about mainVC or it's antecedents so we keep everything loosely-coupled and modular.
Memory
VC1 has not gone away, you still hold two pointers to it:
presentedViewController
propertypresentingViewController
propertyYou can test this by logging, and also just by doing this from VC2
[self dismissViewControllerAnimated:YES completion:nil];
It still works, still gets you back to VC1.
That seems to me like a memory leak.
The clue to this is in the warning you are getting here:
[self presentViewController:vc2 animated:YES completion:nil];
[self dismissViewControllerAnimated:YES completion:nil];
// Attempt to dismiss from view controller <VC1: 0x715e460>
// while a presentation or dismiss is in progress!
The logic breaks down, as you are attempting to dismiss the presenting VC of which VC2 is the presented VC. The second message doesn't really get executed - well perhaps some stuff happens, but you are still left with two pointers to an object you thought you had got rid of. (edit - I've checked this and it's not so bad, both objects do go away when you get back to mainVC)
That's a rather long-winded way of saying - please, use delegates. If it helps, I made another brief description of the pattern here:
Is passing a controller in a construtor always a bad practice?
update 3
If you really want to avoid delegates, this could be the best way out:
In VC1:
[self presentViewController:VC2
animated:YES
completion:nil];
But don't dismiss anything... as we ascertained, it doesn't really happen anyway.
In VC2:
[self.presentingViewController.presentingViewController
dismissViewControllerAnimated:YES
completion:nil];
As we (know) we haven't dismissed VC1, we can reach back through VC1 to MainVC. MainVC dismisses VC1. Because VC1 has gone, it's presented VC2 goes with it, so you are back at MainVC in a clean state.
It's still highly coupled, as VC1 needs to know about VC2, and VC2 needs to know that it was arrived at via MainVC->VC1, but it's the best you're going to get without a bit of explicit delegation.
The answer is - it depends.
Is the variable an instance variable / class variable ? See this for more details.
The list of default values can be found here.
The Groovy script you provided is formatting the first line as a blank line in the resultant script. The shebang, telling the script to run with /bin/bash instead of /bin/sh, needs to be on the first line of the file or it will be ignored.
So instead, you should format your Groovy like this:
stage('Setting the variables values') {
steps {
sh '''#!/bin/bash
echo "hello world"
'''
}
}
And it will execute with /bin/bash.
Regan's answer is great, but it's a bit out of date, since the correct way to do this is avoid the lxc execution context as Docker has dropped LXC as the default execution context as of docker 0.9.
Instead it's better to tell docker about the nvidia devices via the --device flag, and just use the native execution context rather than lxc.
These instructions were tested on the following environment:
See CUDA 6.5 on AWS GPU Instance Running Ubuntu 14.04 to get your host machine setup.
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
$ sudo sh -c "echo deb https://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
$ sudo apt-get update && sudo apt-get install lxc-docker
ls -la /dev | grep nvidia

crw-rw-rw- 1 root root 251, 0 Oct 25 19:37 nvidia-uvm
I've created a docker image that has the cuda drivers pre-installed. The dockerfile is available on dockerhub if you want to know how this image was built.
You'll want to customize this command to match your nvidia devices. Here's what worked for me:
$ sudo docker run -ti --device /dev/nvidia0:/dev/nvidia0 --device /dev/nvidiactl:/dev/nvidiactl --device /dev/nvidia-uvm:/dev/nvidia-uvm tleyden5iwx/ubuntu-cuda /bin/bash
This should be run from inside the docker container you just launched.
Install CUDA samples:
$ cd /opt/nvidia_installers
$ ./cuda-samples-linux-6.5.14-18745345.run -noprompt -cudaprefix=/usr/local/cuda-6.5/
Build deviceQuery sample:
$ cd /usr/local/cuda/samples/1_Utilities/deviceQuery
$ make
$ ./deviceQuery
If everything worked, you should see the following output:
deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 6.5, CUDA Runtime Version = 6.5, NumDevs = 1, Device0 = GRID K520

SSH based git access method can be specified in <repo_path>/.git/config
using either a full URL or an SCP-like syntax, as specified in http://git-scm.com/docs/git-clone:
URL style:
url = ssh://[user@]host.xz[:port]/path/to/repo.git/
SCP style:
url = [user@]host.xz:path/to/repo.git/
Notice that the SCP style does not allow a direct port change, relying instead on an ssh_config
host definition in your ~/.ssh/config
such as:
Host my_git_host
HostName git.some.host.org
Port 24589
User not_a_root_user
Then you can test in a shell with:
ssh my_git_host
and alter your SCP-style URI in <repo_path>/.git/config
as:
url = my_git_host:path/to/repo.git/

Does this give you a hint?
upstream
in the github example is just the name they've chosen to refer to that repository. You may choose any that you like when using git remote add
. Depending on what you select for this name, your git pull
usage will change. For example, if you use:
git remote add upstream git://github.com/somename/original-project.git
then you would use this to pull changes:
git pull upstream master
But, if you choose origin for the name of the remote repo, your commands would be:
To name the remote repo in your local config: git remote add origin git://github.com/somename/original-project.git
And to pull: git pull origin master
When you have changes on your working copy, from command line do:
git stash
This will stash your changes and clear your status report
git pull
This will pull changes from upstream branch. Make sure it says fast-forward in the report. If it doesn't, you are probably doing an unintended merge
git stash pop
This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in stash so you can start over if needed.
if you need to see what is in your stash
git stash list

I dont have a copy of Delphi to hand, but I'm fairly certain if you set the wordwrap property to true and the autosize property to false it should wrap any text you put it at the size you make the label. If you want to line break in a certain place then it might work if you set the above settings and paste from a text editor.
Hope this helps.
in your location block you can do:
location / {
try_files $uri $uri/index.html;
}
which will tell ngingx to look for a file with the exact name given first, and if none such file is found it will try uri/index.html. So if a request for https://www.example.com/ comes it it would look for an exact file match first, and not finding that would then check for index.html
Both the regex and included files are good methods, and I frequently use those. But another alternative is to use a "named location", which is a useful approach in many situations — especially more complicated ones. The official "If is Evil" page shows essentially the following as a good way to do things:
error_page 418 = @common_location;
location /first/location/ {
return 418;
}
location /second/location/ {
return 418;
}
location @common_location {
# The common configuration...
}
There are advantages and disadvantages to these various approaches. One big advantage to a regex is that you can capture parts of the match and use them to modify the response. Of course, you can usually achieve similar results with the other approaches by either setting a variable in the original block or using map
. The downside of the regex approach is that it can get unwieldy if you want to match a variety of locations, plus the low precedence of a regex might just not fit with how you want to match locations — not to mention that there are apparently performance impacts from regexes in some cases.
The main advantage of including files (as far as I can tell) is that it is a little more flexible about exactly what you can include — it doesn't have to be a full location block, for example. But it's also just subjectively a bit clunkier than named locations.
Also note that there is a related solution that you may be able to use in similar situations: nested locations. The idea is that you would start with a very general location, apply some configuration common to several of the possible matches, and then have separate nested locations for the different types of paths that you want to match. For example, it might be useful to do something like this:
location /specialpages/ {
# some config
location /specialpages/static/ {
try_files $uri $uri/ =404;
}
location /specialpages/dynamic/ {
proxy_pass http://127.0.0.1;
}
}

Think of 0 as false and 1 as true. Then bitwise and(&) and or(|) work just like regular and and or except they do all of the bits in the value at once. Typically you will see them used for flags if you have 30 options that can be set (say as draw styles on a window) you don't want to have to pass in 30 separate boolean values to set or unset each one so you use | to combine options into a single value and then you use & to check if each option is set. This style of flag passing is heavily used by OpenGL. Since each bit is a separate flag you get flag values on powers of two(aka numbers that have only one bit set) 1(2^0) 2(2^1) 4(2^2) 8(2^3) the power of two tells you which bit is set if the flag is on.
Also note 2 = 10 so x|2 is 110(6) not 111(7) If none of the bits overlap(which is true in this case) | acts like addition.

Note that that won't work in IE6 (maybe 7 not sure)
there you will have to do on .image_block
the container Div
text-align:center;
position:relative;
could be a problem too.
Two options:
for (let item in MotifIntervention) {
if (isNaN(Number(item))) {
console.log(item);
}
}
Or
Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));
String enums look different than regular ones, for example:
enum MyEnum {
A = "a",
B = "b",
C = "c"
}
Compiles into:
var MyEnum;
(function (MyEnum) {
MyEnum["A"] = "a";
MyEnum["B"] = "b";
MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));
Which just gives you this object:
{
A: "a",
B: "b",
C: "c"
}
You can get all the keys (["A", "B", "C"]
) like this:
Object.keys(MyEnum);
And the values (["a", "b", "c"]
):
Object.keys(MyEnum).map(key => MyEnum[key])
Or using Object.values():
Object.values(MyEnum)
From Java 8 you can use :
Comparator.comparingInt(Dog::getDogAge).reversed();
Inspired by this really neat answer: (https://stackoverflow.com/a/49572324/4808079)
You can do lamba closures:
// Nobody wants to remember the order of these things
struct SomeBigStruct {
int min = 1;
int mean = 3 ;
int mode = 5;
int max = 10;
string name;
string nickname;
... // the list goes on
}
.
class SomeClass {
static const inline SomeBigStruct voiceAmps = []{
ModulationTarget $ {};
$.min = 0;
$.nickname = "Bobby";
$.bloodtype = "O-";
return $;
}();
}
Or, if you want to be very fancy
#define DesignatedInit(T, ...)\
[]{ T ${}; __VA_ARGS__; return $; }()
class SomeClass {
static const inline SomeBigStruct voiceAmps = DesignatedInit(
ModulationTarget,
$.min = 0,
$.nickname = "Bobby",
$.bloodtype = "O-",
);
}
There are some drawbacks involved with this, mostly having to do with uninitialized members. From what the linked answers comments say, it compiles efficiently, though I have not tested it.
Overall, I just think it's a neat approach.
Regarding commits, refs, branches and "et cetera", Magnus answer just works (git remote update
).
But unfortunately there is no way to clone
/ mirror / update
the hooks, as I wanted...
I have found this very interesting thread about cloning/mirroring the hooks:
http://kerneltrap.org/mailarchive/git/2007/8/28/256180/thread
I learned:
The hooks are not considered part of the repository contents.
There is more data, like the .git/description
folder, which does not get cloned, just as the hooks.
The default hooks that appear in the hooks
dir comes from the TEMPLATE_DIR
There is this interesting template
feature on git.
So, I may either ignore this "clone the hooks thing", or go for a rsync
strategy, given the purposes of my mirror (backup + source for other clones, only).
Well... I will just forget about hooks cloning, and stick to the git remote update
way.
clone
/ update
process, but also stashes, rerere, etc... So, for a strict backup, rsync
or equivalent would really be the way to go. As this is not really necessary in my case (I can afford not having hooks, stashes, and so on), like I said, I will stick to the remote update
.Thanks! Improved a bit of my own "git-fu"... :-)
Design support library for androidX is implementation 'com.google.android.material:material:1.0.0'
Assuming you are using Python 3.x:
print(*myList, sep='\n')
You can get the same behavior on Python 2.x using from __future__ import print_function
, as noted by mgilson in comments.
With the print statement on Python 2.x you will need iteration of some kind, regarding your question about print(p) for p in myList
not working, you can just use the following which does the same thing and is still one line:
for p in myList: print p
For a solution that uses '\n'.join()
, I prefer list comprehensions and generators over map()
so I would probably use the following:
print '\n'.join(str(p) for p in myList)
Use PHP's popen
command, e.g.:
pclose(popen("start c:\wamp\bin\php.exe c:\wamp\www\script.php","r"));
This will create a child process and the script will excute in the background without waiting for output.
try this
var YourURL = "http://yourUrl/";
HttpClientHandler handler = new HttpClientHandler()
{
Proxy = new WebProxy("http://127.0.0.1:8888"),
UseProxy = true,
};
Console.WriteLine(YourURL);
HttpClient client = new HttpClient(handler);
import numpy as np
hist, bin_edges = np.histogram([1, 1, 2, 2, 2, 2, 3], bins = range(5))
Below, hist
indicates that there are 0 items in bin #0, 2 in bin #1, 4 in bin #3, 1 in bin #4.
print(hist)
# array([0, 2, 4, 1])
bin_edges
indicates that bin #0 is the interval [0,1), bin #1 is [1,2), ...,
bin #3 is [3,4).
print (bin_edges)
# array([0, 1, 2, 3, 4]))
Play with the above code, change the input to np.histogram
and see how it works.
But a picture is worth a thousand words:
import matplotlib.pyplot as plt
plt.bar(bin_edges[:-1], hist, width = 1)
plt.xlim(min(bin_edges), max(bin_edges))
plt.show()
Context bindings in .NET 3.5 might be just what you're looking for. There are three out of the box: BasicHttpContextBinding, NetTcpContextBinding, and WSHttpContextBinding. Context protocol basically passes key-value pairs in the message header. Check out Managing State With Durable Services article on MSDN magazine.
I did some benchmarking and it turns out that dict is faster than both list and set for large data sets, running python 2.7.3 on an i7 CPU on linux:
python -mtimeit -s 'd=range(10**7)' '5*10**6 in d'
10 loops, best of 3: 64.2 msec per loop
python -mtimeit -s 'd=dict.fromkeys(range(10**7))' '5*10**6 in d'
10000000 loops, best of 3: 0.0759 usec per loop
python -mtimeit -s 'from sets import Set; d=Set(range(10**7))' '5*10**6 in d'
1000000 loops, best of 3: 0.262 usec per loop
As you can see, dict is considerably faster than list and about 3 times faster than set. In some applications you might still want to choose set for the beauty of it, though. And if the data sets are really small (< 1000 elements) lists perform pretty well.
You can utilize ARGV:
v=123test
awk 'BEGIN {print ARGV[1]}' "$v"
Note that if you are going to continue into the body, you will need to adjust ARGC:
awk 'BEGIN {ARGC--} {print ARGV[2], $0}' file "$v"
I created a plugin which allows you to drop some files onto a given area. This plugin currently works in Firefox, Safari and Chrome.
Another problem solved by the rubber duck:
The css is right but you still have to remember that the HTML elements order matters: the div has to come before the header. http://jsfiddle.net/Fq2Na/1/
Change your HTML code to have the div before the header:
<section>
<div><button>button</button></div>
<h1>some long long long long header, a whole line, 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6</h1>
</section>
And keep your CSS to the simple div { float: right; }
.
if you want to specifically find strings which ends with desired characters then this would help you...
select * from tablename where col_name like '%190'
I tested and used this command in kafka confluent V4.0.0
and apache kafka V 1.0.0 and 1.0.1
/opt/kafka/confluent-4.0.0/bin/kafka-configs --zookeeper XX.XX.XX.XX:2181 --entity-type topics --entity-name test --alter --add-config retention.ms=55000
test
is the topic name.
I think it works well in other versions too
I am using both JavaScript Cookie and Java CookieUtil in my project, below settings solved my problem:
JavaScript Cookie
var d = new Date();
d.setTime(d.getTime() + (30*24*60*60*1000)); //keep cookie 30 days
var expires = "expires=" + d.toGMTString();
document.cookie = "visitName" + "=Hailin;" + expires + ";path=/;SameSite=None;Secure"; //can set SameSite=Lax also
JAVA Cookie (set proxy_cookie_path in Nginx)
location / {
proxy_pass http://96.xx.xx.34;

Answers so far did not adress the problem of sharing code with other people who don't necessarily use Eclipse. Here is one proposition. The key is to use a maven profile to solve the Eclipse Case.
It assumes you have defined a property junit5.version
in your pom like:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<junit5.version>5.1.1</junit5.version>
</properties>
then in the profiles
section add the following:
<profiles>
<profile>
<id>eclipse</id>
<dependencies>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
</dependency>
<dependency>
<groupId>org.junit.platform</groupId>
<artifactId>junit-platform-launcher</artifactId>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
<version>${junit5.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.junit.platform</groupId>
<artifactId>junit-platform-launcher</artifactId>
<version>1.1.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</dependencyManagement>
</profile>
</profiles>
All you have to do after this is to select the profile in your local Eclipse: Right click on your project and select Maven > Select Maven Profiles...
(or hit Ctrl + Alt + P), and then check the "eclipse" profile we just created.
With that you are done. Your Eclipse will run Junit 5 tests as expected, but the configuration you added won't pollute other builds or other IDE
Just to add to the other answers, if you would prefer to return a vector rather than a dataframe, you have the following options:
dplyr < 0.7.0
Enclose the dplyr functions in a parentheses and combine it with $
syntax:
(mtcars %>% distinct(cyl))$cyl
dplyr >= 0.7.0
Use the pull
verb:
mtcars %>% distinct(cyl) %>% pull()
From Microsoft documentation:
PAGEIOLATCH_SH
Occurs when a task is waiting on a latch for a buffer that is in an
I/O
request. The latch request is in Shared mode. Long waits may indicate problems with the disk subsystem.
In practice, this almost always happens due to large scans over big tables. It almost never happens in queries that use indexes efficiently.
If your query is like this:
Select * from <table> where <col1> = <value> order by <PrimaryKey>
, check that you have a composite index on (col1, col_primary_key)
.
If you don't have one, then you'll need either a full INDEX SCAN
if the PRIMARY KEY
is chosen, or a SORT
if an index on col1
is chosen.
Both of them are very disk I/O
consuming operations on large tables.
I think you can create a simple SQL query:
$sql="select username from user where id in (select id from idtables)";
$query=$this->db->query($sql);
and then you can use it normally.
You can like:
window.open('url', 'window name', 'window settings')
jQuery:
$('a#link_id').click(function(){
window.open('url', 'window name', 'window settings');
return false;
});
You could also set the target
to _blank
actually.
Remove javascript:
from onclick="..
, onsubmit="..
declarations
javascript:
prefix is used only in href=""
or similar attributes (not events related)
You also need to set the option CURLOPT_COOKIEFILE
.
The manual describes this as
The name of the file containing the cookie data. The cookie file can be in Netscape format, or just plain HTTP-style headers dumped into a file. If the name is an empty string, no cookies are loaded, but cookie handling is still enabled.
Since you are using the cookie jar you end up saving the cookies when the requests finish, but since the CURLOPT_COOKIEFILE
is not given, cURL isn't sending any of the saved cookies on subsequent requests.
The hint is, the output file is created even if you get this error. The automatic deconstruction of vector starts after your code executed. Elements in the vector are deconstructed as well. This is most probably where the error occurs. The way you access the vector is through vector::operator[]
with an index read from stream. Try vector::at()
instead of vector::operator[]
. This won't solve your problem, but will show which assignment to the vector causes error.
Nobody mentioned tig
? It doesn't fold branches like "BranchMaster", but...
It is fast, runs in the terminal.
Because it is so quick (+ keyboard control) you get a great UX,
it is almost like my "ls
" for directories containing git repositories.
It has the usual shortcuts, /
to search, etc.
(ps. it is the terminal in the background of this screenshot, it looks better nowadays, but my computer refuses to take a screenshot, sorry)
(pps. I use gitkraken as well and has really clear visualisations, but it's much heavier than tig
)
for (Map.Entry<String, ArrayList<String>> entry : test1.entrySet()) {
String key = entry.getKey();
ArrayList<String> value = entry.getValue();
// now work with key and value...
}
By the way, you should really declare your variables as the interface type instead, such as Map<String, List<String>>
.
Okay I modifed @AndroidMechanics Code, because on devices were facebook is disabled the app crashes!
here is the modifed getFacebookUrl:
public String getFacebookPageURL(Context context) {
PackageManager packageManager = context.getPackageManager();
try {
int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
boolean activated = packageManager.getApplicationInfo("com.facebook.katana", 0).enabled;
if(activated){
if ((versionCode >= 3002850)) {
return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
} else {
return "fb://page/" + FACEBOOK_PAGE_ID;
}
}else{
return FACEBOOK_URL;
}
} catch (PackageManager.NameNotFoundException e) {
return FACEBOOK_URL;
}
}
The only added thing is to look if the app is disabled or not if it is disabled the app will call the webbrowser!
ProgressBar color can be changed as follows:
/res/values/colors.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorAccent">#FF4081</color>
</resources>
/res/values/styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorAccent">@color/colorAccent</item>
</style>
onCreate:
progressBar = (ProgressBar) findViewById(R.id.progressBar);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
Drawable drawable = progressBar.getIndeterminateDrawable().mutate();
drawable.setColorFilter(ContextCompat.getColor(this, R.color.colorAccent), PorterDuff.Mode.SRC_IN);
progressBar.setIndeterminateDrawable(drawable);
}
yourEnum.ordinal()
EnumType.values()[someInt]
EnumType.valueOf(yourString)
yourEnum.name()
A side-note:
As you correctly point out, the ordinal()
may be "unstable" from version to version. This is the exact reason why I always store constants as strings in my databases. (Actually, when using MySql, I store them as MySql enums!)
A file containing some statements :
cat test.txt
Result :
This is the 1st Statement
This is the 2nd Statement
This is the 3rd Statement
This is the 4th Statement
This is the 5th Statement
So, to print the 4th word of this statement type :
cat test.txt |awk '{print $4}'
Output :
1st
2nd

I made the member function as static and all works:
#include <iostream>
class aClass
{
public:
static void aTest(int a, int b)
{
printf("%d + %d = %d\n", a, b, a + b);
}
};
void function1(int a,int b,void function(int, int))
{
function(a, b);
}
void test(int a,int b)
{
printf("%d - %d = %d\n", a , b , a - b);
}
int main (int argc, const char* argv[])
{
aClass a;
function1(10,12,test);
function1(10,12,a.aTest); // <-- How should I point to a's aClass::test function?
getchar();return 0;
}

Both syntaxes are correct. But the result would be Array
. You probably want to do something like this:
foreach ($tmpArray[1] as $value) {
echo $value[0];
foreach($value[1] as $val){
echo $val;
}
}
This will print out the string "two" ($value[0]) and the integers 4, 5 and 6 from the array ($value[1]).
With examples? Here's a simple one:
public class TwoInjectionStyles {
private Foo foo;
// Constructor injection
public TwoInjectionStyles(Foo f) {
this.foo = f;
}
// Setting injection
public void setFoo(Foo f) { this.foo = f; }
}
Personally, I prefer constructor injection when I can.
In both cases, the bean factory instantiates the TwoInjectionStyles
and Foo
instances and gives the former its Foo
dependency.
After testing I found that it was not the decimal place that was causing the problem, it was the precision (10)
This doesn't work: Arithmetic overflow error converting varchar to data type numeric.
DECLARE @TestConvert VARCHAR(MAX) = '123456789.12343594'

This worked
DECLARE @TestConvert VARCHAR(MAX) = '123456789.12343594'
SELECT CAST(@TestConvert AS DECIMAL(18, 4))
you need to use display = none

Ctrl + K + D for front end pages like .aspx

There is an extra ')'

Remove that and it will work fine.

Sure you can.
ALTER TABLE myTable ALTER COLUMN myColumn int NULL
Just substitute int for whatever datatype your column is.
Use !empty()
instead of isset()
. Because isset()
will always return true in your case.
if (!empty($_POST["mail"])) {
echo "Yes, mail is entered";
} else {
echo "No, mail is not entered";
}
The definition of "the number of months in the difference" is subject to a lot of interpretation. :-)
You can get the year, month, and day of month from a JavaScript date object. Depending on what information you're looking for, you can use those to figure out how many months are between two points in time.
For instance, off-the-cuff:
function monthDiff(d1, d2) {
var months;
months = (d2.getFullYear() - d1.getFullYear()) * 12;
months -= d1.getMonth();
months += d2.getMonth();
return months <= 0 ? 0 : months;
}
function monthDiff(d1, d2) {_x000D_
var months;_x000D_
months = (d2.getFullYear() - d1.getFullYear()) * 12;_x000D_
months -= d1.getMonth();_x000D_
months += d2.getMonth();_x000D_
return months <= 0 ? 0 : months;_x000D_
}_x000D_

(Note that month values in JavaScript start with 0 = January.)
Including fractional months in the above is much more complicated, because three days in a typical February is a larger fraction of that month (~10.714%) than three days in August (~9.677%), and of course even February is a moving target depending on whether it's a leap year.
There are also some date and time libraries available for JavaScript that probably make this sort of thing easier.
Note: There used to be a + 1
in the above, here:
months = (d2.getFullYear() - d1.getFullYear()) * 12;
months -= d1.getMonth() + 1;
// --------------------^^^^
months += d2.getMonth();
That's because originally I said:
...this finds out how many full months lie between two dates, not counting partial months (e.g., excluding the month each date is in).
I've removed it for two reasons:
Not counting partial months turns out not to be what many (most?) people coming to the answer want, so I thought I should separate them out.
It didn't always work even by that definition. :-D (Sorry.)
Yes, this is definitely possible. For example, sorting n
real numbers requires O(n)
space, but O(n log n)
time. It is true that space complexity is always a lowerbound on time complexity, as the time to initialize the space is included in the running time.
make these changes in your div's style
z-index:100;
some higher value makes sure that this element is above allposition:fixed;
this makes sure that even if scrolling is done, div lies on top and always visible
For beginners, I wanted to add to the accepted answer, because a couple of subtleties were unclear to me:
To find and modify text (not completely replace),
In the "Find" step, you can use regex with "capturing groups," e.g. your search could be la la la (group1) blah blah (group2)
, using parentheses.
And then in the "Replace" step, you can refer to the capturing groups via $1
, $2
etc.
So, for example, in this case we could find the relevant text with just <h1>.+?<\/h1>
(no parentheses), but putting in the parentheses <h1>(.+?)<\/h1>
allows us to refer to the sub-match in between them as $1
in the replace step. Cool!
Notes
To turn on Regex in the Find Widget, click the .*
icon, or press Cmd/Ctrl
Alt
R
$0
refers to the whole match
Finally, the original question states that the replace should happen "within a document," so you can use the "Find Widget" (Cmd
or Ctrl
+ F
), which is local to the open document, instead of "Search", which opens a bigger UI and looks across all files in the project.
Instead of
host = socket.gethostname() #Get the local machine name
port = 12397 # Reserve a port for your service
s.bind((host,port)) #Bind to the port
you should try
port = 12397 # Reserve a port for your service
s.bind(('', port)) #Bind to the port
so that the listening socket isn't too restricted. Maybe otherwise the listening only occurs on one interface which, in turn, isn't related with the local network.
One example could be that it only listens to 127.0.0.1
, which makes connecting from a different host impossible.
you need to add Junit dependency in pom.xml file, it means you need to update with latest version.

To view your recent work and what branch it happened on run
git stash list
then select the stash to apply and use only number:
git stash apply n
Where n
(in the above sample) is that number corresponding to the Work In Progress.
The date values from the text fields can be fetched by jquery's .val() Method like
var datestr1 = $('#datefield1-id').val();
var datestr2 = $('#datefield2-id').val();
I'd strongly recommend to parse the date strings before comparing them. Javascript's Date object has a parse()-Method, but it only supports US date formats (YYYY/MM/DD). It returns the milliseconds since the beginning of the unix epoch, so you can simply compare your values with > or <.
If you want different formats (e.g. ISO 8661), you need to resort to regular expressions or the free date.js library.
If you want to be super user-fiendly, you can use jquery ui datepickers instead of textfields. There is a datepicker variant that allows to enter date ranges:

For anyone stumbling across the same issue:
I fixed the problem by cloning the repo again at another location. I then copied my whole src dir (without .git dir obviously) from the corrupted repo into the freshly cloned repo. Thus I had all the recent changes and a clean and working repository.
You're escaping the backslash when the at sign does that for you.

Quick, interactive way to see column names
If you're working interactively in Python and just want to quickly 'see' the column names, I found cursor.description to work.
import sqlite3
conn = sqlite3.connect('test-db.db')
cursor = conn.execute('select * from mytable')
cursor.description
Outputs something like this:
(('Date', None, None, None, None, None, None),
('Object-Name', None, None, None, None, None, None),
('Object-Count', None, None, None, None, None, None))
Or, quick way to access and print them out.
colnames = cursor.description
for row in colnames:
print row[0]
Outputs something like this:
Date
Object-Name
Object-Count
You can create you own operator :
'%&%' <- function(x, y)paste0(x,y)
"new" %&% "operator"
[1] newoperator`
You can also redefine 'and' (&
) operator :
'&' <- function(x, y)paste0(x,y)
"dirty" & "trick"
"dirtytrick"
messing with baseline syntax is ugly, but so is using paste()/paste0()
if you work only with your own code you can (almost always) replace logical & and
operator with *
and do multiplication of logical values instead of using logical 'and &'
gacutil comes with Visual Studio, not with VSTS. It is part of Windows SDK and can be download separately at http://www.microsoft.com/downloads/details.aspx?FamilyId=F26B1AA4-741A-433A-9BE5-FA919850BDBF&displaylang=en . This installation will have gacutil.exe
included. But first check it here
C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin
you might have it installed.
As @devi mentioned
If you decide to grab gacutil files from existing installation, note that from .NET 4.0 is three files: gacutil.exe gacutil.exe.config and 1033/gacutlrc.dll
with paging you need to do some calculation
int index = Convert.ToInt32(e.CommandArgument) % GridView1.PageSize;
%hash1 = (%hash1, %hash2) ## or else ... @hash1{keys %hash2} = values %hash2; ## or with references ... $hash_ref1 = { %$hash_ref1, %$hash_ref2 };
undef
, zero, empty string, false
, falsy ...)1 * (aka associative-array, aka dictionary)
Another useful time to include @ is when you use FOR
in the command line. For example:
FOR %F IN (*.*) DO ECHO %F
Previous line show for every file: the command prompt, the ECHO
command, and the result of ECHO
command. This way:
FOR %F IN (*.*) DO @ECHO %F
Just the result of ECHO
command is shown.
For static analysis, I've used and recommend SonarQube which runs just about all the metrics you could possibly want on a wide range of languages, and is free in the basic version (you have to pay to analyse the sorts of languages I'd only code in with a gun to my head).
You have to install it as a web-app running the analysis off your source code repository, but it also has an Eclipse plugin.
It's overkill if you just want to know, as a one-off, how many lines of code there are in your project. If you want to track metrics through time, compare across projects, fire warnings when a threshold is exceeded, etc., it's fantastic.
Disclosure: I have no financial relationship with SonarSource.
This regex pattern will match an empty string:
^$
And this will match (crudely) an email or an empty string:
(^$|^.*@.*\..*$)
(Following is a late but complete answer)
FileReader.readAsBinaryString()
is deprecated. Don't use it! It's no longer in the W3C File API working draft:
void abort();
void readAsArrayBuffer(Blob blob);
void readAsText(Blob blob, optional DOMString encoding);
void readAsDataURL(Blob blob);
NB: Note that File
is a kind of extended Blob
structure.
Mozilla still implements readAsBinaryString()
and describes it in MDN FileApi documentation:
void abort();
void readAsArrayBuffer(in Blob blob); Requires Gecko 7.0
void readAsBinaryString(in Blob blob);
void readAsDataURL(in Blob file);
void readAsText(in Blob blob, [optional] in DOMString encoding);
The reason behind readAsBinaryString()
deprecation is in my opinion the following: the standard for JavaScript strings are DOMString
which only accept UTF-8 characters, NOT random binary data. So don't use readAsBinaryString(), that's not safe and ECMAScript-compliant at all.
We know that JavaScript strings are not supposed to store binary data but Mozilla in some sort can. That's dangerous in my opinion. Blob
and typed arrays
(ArrayBuffer
and the not-yet-implemented but not necessary StringView
) were invented for one purpose: allow the use of pure binary data, without UTF-8 strings restrictions.
XMLHttpRequest.send()
has the following invocations options:
void send();
void send(ArrayBuffer data);
void send(Blob data);
void send(Document data);
void send(DOMString? data);
void send(FormData data);
XMLHttpRequest.sendAsBinary()
has the following invocations options:
void sendAsBinary( in DOMString body );
sendAsBinary() is NOT a standard and may not be supported in Chrome.
So you have several options:
send()
the FileReader.result
of FileReader.readAsArrayBuffer ( fileObject )
. It is more complicated to manipulate (you'll have to make a separate send() for it) but it's the RECOMMENDED APPROACH.send()
the FileReader.result
of FileReader.readAsDataURL( fileObject )
. It generates useless overhead and compression latency, requires a decompression step on the server-side BUT it's easy to manipulate as a string in Javascript.sendAsBinary()
the FileReader.result
of FileReader.readAsBinaryString( fileObject )
MDN states that:
The best way to send binary content (like in files upload) is using ArrayBuffers or Blobs in conjuncton with the send() method. However, if you want to send a stringifiable raw data, use the sendAsBinary() method instead, or the StringView (Non native) typed arrays superclass.
My experience with trying to use CSS to modify the scroll bars is don't. Only IE will let you do this.
Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.
The relevant paragraph:
Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.
This makes lots of sense.
For your specific question.. the o
in the <o:p>
means "Office namespace" so anything following the o:
in a tag means "I'm part of Office namespace" - in case of <o:p>
it just means paragraph, the equivalent of the ordinary <p>
tag.
I assume that every HTML tag has its Office "equivalent" and they have more.
INTRODUCTION
This answer corrects the very broken but shockingly top voted answer of this thread (written by TheMarko):
#!/usr/bin/env bash
BASEDIR=$(dirname "$0")
echo "$BASEDIR"
WHY DOES USING dirname "$0" ON IT'S OWN NOT WORK?
dirname $0 will only work if user launches script in a very specific way. I was able to find several situations where this answer fails and crashes the script.
First of all, let's understand how this answer works. He's getting the script directory by doing
dirname "$0"
$0 represents the first part of the command calling the script (it's basically the inputted command without the arguments:
/some/path/./script argument1 argument2
$0="/some/path/./script"
dirname basically finds the last / in a string and truncates it there. So if you do:
dirname /usr/bin/sha256sum
you'll get: /usr/bin
This example works well because /usr/bin/sha256sum is a properly formatted path but
dirname "/some/path/./script"
wouldn't work well and would give you:
BASENAME="/some/path/." #which would crash your script if you try to use it as a path
Say you're in the same dir as your script and you launch it with this command
./script
$0 in this situation will be ./script and dirname $0 will give:
. #or BASEDIR=".", again this will crash your script
Using:
sh script
Without inputting the full path will also give a BASEDIR="."
Using relative directories:
../some/path/./script
Gives a dirname $0 of:
../some/path/.
If you're in the /some directory and you call the script in this manner (note the absence of / in the beginning, again a relative path):
path/./script.sh
You'll get this value for dirname $0:
path/.
and ./path/./script (another form of the relative path) gives:
./path/.
The only two situations where basedir $0 will work is if the user use sh or touch to launch a script because both will result in $0:
$0=/some/path/script
which will give you a path you can use with dirname.
THE SOLUTION
You'd have account for and detect every one of the above mentioned situations and apply a fix for it if it arises:
#!/bin/bash
#this script will only work in bash, make sure it's installed on your system.
#set to false to not see all the echos
debug=true
if [ "$debug" = true ]; then echo "\$0=$0";fi
#The line below detect script's parent directory. $0 is the part of the launch command that doesn't contain the arguments
BASEDIR=$(dirname "$0") #3 situations will cause dirname $0 to fail: #situation1: user launches script while in script dir ( $0=./script)
#situation2: different dir but ./ is used to launch script (ex. $0=/path_to/./script)
#situation3: different dir but relative path used to launch script
if [ "$debug" = true ]; then echo 'BASEDIR=$(dirname "$0") gives: '"$BASEDIR";fi
if [ "$BASEDIR" = "." ]; then BASEDIR="$(pwd)";fi # fix for situation1
_B2=${BASEDIR:$((${#BASEDIR}-2))}; B_=${BASEDIR::1}; B_2=${BASEDIR::2}; B_3=${BASEDIR::3} # <- bash only
if [ "$_B2" = "/." ]; then BASEDIR=${BASEDIR::$((${#BASEDIR}-1))};fi #fix for situation2 # <- bash only
if [ "$B_" != "/" ]; then #fix for situation3 #<- bash only
if [ "$B_2" = "./" ]; then
#covers ./relative_path/(./)script
if [ "$(pwd)" != "/" ]; then BASEDIR="$(pwd)/${BASEDIR:2}"; else BASEDIR="/${BASEDIR:2}";fi
else
#covers relative_path/(./)script and ../relative_path/(./)script, using ../relative_path fails if current path is a symbolic link
if [ "$(pwd)" != "/" ]; then BASEDIR="$(pwd)/$BASEDIR"; else BASEDIR="/$BASEDIR";fi
fi
fi
if [ "$debug" = true ]; then echo "fixed BASEDIR=$BASEDIR";fi
i found another solution:
Its 100% guaranteed to work.
I just solved it this way
Html:
<div class="custom-file">
<input id="logo" type="file" class="custom-file-input">
<label for="logo" class="custom-file-label text-truncate">Choose file...</label>
</div>
JS:
$('.custom-file-input').on('change', function() {
let fileName = $(this).val().split('\\').pop();
$(this).next('.custom-file-label').addClass("selected").html(fileName);
});
Note: Thanks to ajax333221 for mentioning the .text-truncate
class that will hide the overflow within label if the selected file name is too long.
I think you are getting confused about what the a:active
CSS selector does. This will only change the colour of your link when you click it (and only for the duration of the click i.e. how long your mouse button stays down). What you need to do is introduce a new class e.g. .selected
into your CSS and when you select a link, update the selected menu item with new class e.g.
<div class="menuBar">
<ul>
<li class="selected"><a href="index.php">HOME</a></li>
<li><a href="two.php">PORTFOLIO</a></li>
....
</ul>
</div>
// specific CSS for your menu
div.menuBar li.selected a { color: #FF0000; }
// more general CSS
li.selected a { color: #FF0000; }
You will need to update your template page to take in a selectedPage
parameter.
Just check the project.pbproject file and do a diff against a working version of the project file.
Often times this happens when you have conflicts from a version control system like posted here: User file cannot be parsed in subversion in MAC iphone SDK
There is no way to do this in the GitHub web application. I believe to only way to do this is in the command line using git mv <old name> <new name>
or by using a Git client(like SourceTree).
You are trying to call DeckOfCards::shuffle
with a deckOfCards
parameter:
deckOfCards cardDeck; // create DeckOfCards object
cardDeck.shuffle(cardDeck); // shuffle the cards in the deck
But the method takes a vector<Card>&
:
void deckOfCards::shuffle(vector<Card>& deck)
The compiler error messages are quite clear on this. I'll paraphrase the compiler as it talks to you.
Error:
[Error] no matching function for call to 'deckOfCards::shuffle(deckOfCards&)'
Paraphrased:
Hey, pal. You're trying to call a function called
shuffle
which apparently takes a single parameter of type reference-to-deckOfCards
, but there is no such function.
Error:
[Note] candidate is:
In file included from main.cpp
[Note] void deckOfCards::shuffle(std::vector&)
Paraphrased:
I mean, maybe you meant this other function called
shuffle
, but that one takes a reference-tovector<something>
.
Error:
[Note] no known conversion for argument 1 from 'deckOfCards' to 'std::vector&'
Which I'd be happy to call if I knew how to convert from a
deckOfCards
to avector
; but I don't. So I won't.
The other answers all use Arrays.asList()
, which returns an unmodifiable list (an UnsupportedOperationException
is thrown if you try to add or remove an element). To get a mutable list you can wrap the returned list in a new ArrayList
as a couple of answers point out, but a cleaner solution is to use Guava's Lists.newArrayList() (available since at least Guava 10, released in 2011).
For example:
Lists.newArrayList("Blargle!");
I use this function :
function array_sort_by_column(&$arr, $col, $dir = SORT_ASC) {
$sort_col = array();
foreach ($arr as $key=> $row) {
$sort_col[$key] = $row[$col];
}
array_multisort($sort_col, $dir, $arr);
}
array_sort_by_column($array, 'order');
On OSX, saving video frames and still images only worked for me when I gave a full path to cvSaveImage:
cvSaveImage("/Users/nicc/image.jpg",img);
If your class extends Serializable
, you can write and read objects through a ByteArrayOutputStream
, that's what I usually do.
You must have to define no-args or default constructor if you are creating your own constructor.
You can read why default or no argument constructor is required.
Simpler with the aggregate function string_agg()
(Postgres 9.0 or later):
SELECT movie, string_agg(actor, ', ') AS actor_list
FROM tbl
GROUP BY 1;
The 1
in GROUP BY 1
is a positional reference and a shortcut for GROUP BY movie
in this case.
string_agg()
expects data type text
as input. Other types need to be cast explicitly (actor::text
) - unless an implicit cast to text
is defined - which is the case for all other character types (varchar
, character
, "char"
), and some other types.
As isapir commented, you can add an ORDER BY
clause in the aggregate call to get a sorted list - should you need that. Like:
SELECT movie, string_agg(actor, ', ' ORDER BY actor) AS actor_list
FROM tbl
GROUP BY 1;
But it's typically faster to sort rows in a subquery. See:
The %#08X
conversion must precede the value with 0X
; that is required by the standard. There's no evidence in the standard that the #
should alter the behaviour of the 08
part of the specification except that the 0X
prefix is counted as part of the length (so you might want/need to use %#010X
. If, like me, you like your hex presented as 0x1234CDEF
, then you have to use 0x%08X
to achieve the desired result. You could use %#.8X
and that should also insert the leading zeroes.
Try variations on the following code:
#include <stdio.h>
int main(void)
{
int j = 0;
printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
for (int i = 0; i < 8; i++)
{
j = (j << 4) | (i + 6);
printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
}
return(0);
}
On an RHEL 5 machine, and also on Mac OS X (10.7.5), the output was:
0x00000000 = 00000000 = 00000000 = 0000000000
0x00000006 = 0X000006 = 0X00000006 = 0x00000006
0x00000067 = 0X000067 = 0X00000067 = 0x00000067
0x00000678 = 0X000678 = 0X00000678 = 0x00000678
0x00006789 = 0X006789 = 0X00006789 = 0x00006789
0x0006789A = 0X06789A = 0X0006789A = 0x0006789a
0x006789AB = 0X6789AB = 0X006789AB = 0x006789ab
0x06789ABC = 0X6789ABC = 0X06789ABC = 0x06789abc
0x6789ABCD = 0X6789ABCD = 0X6789ABCD = 0x6789abcd
I'm a little surprised at the treatment of 0; I'm not clear why the 0X
prefix is omitted, but with two separate systems doing it, it must be standard. It confirms my prejudices against the #
option.
The treatment of zero is according to the standard.
ISO/IEC 9899:2011 §7.21.6.1 The
fprintf
function¶6 The flag characters and their meanings are:
...
#
The result is converted to an "alternative form". ... Forx
(orX
) conversion, a nonzero result has0x
(or0X
) prefixed to it. ...
(Emphasis added.)
Note that using %#X
will use upper-case letters for the hex digits and 0X
as the prefix; using %#x
will use lower-case letters for the hex digits and 0x
as the prefix. If you prefer 0x
as the prefix and upper-case letters, you have to code the 0x
separately: 0x%X
. Other format modifiers can be added as needed, of course.
For printing addresses, use the <inttypes.h>
header and the uintptr_t
type and the PRIXPTR
format macro:
#include <inttypes.h>
#include <stdio.h>
int main(void)
{
void *address = &address; // &address has type void ** but it converts to void *
printf("Address 0x%.12" PRIXPTR "\n", (uintptr_t)address);
return 0;
}
Example output:
Address 0x7FFEE5B29428
Choose your poison on the length — I find that a precision of 12 works well for addresses on a Mac running macOS. Combined with the .
to specify the minimum precision (digits), it formats addresses reliably. If you set the precision to 16, the extra 4 digits are always 0 in my experience on the Mac, but there's certainly a case to be made for using 16 instead of 12 in portable 64-bit code (but you'd use 8 for 32-bit code).
You can also use linq extensions for DataSets:
var imagePaths = dt.AsEnumerble().Select(r => r.Field<string>("ImagePath");
foreach(string imgPath in imagePaths)
{
TextBox1.Text = imgPath;
}
Works with over 100 lines, if you specify the size of the file in the headers simple call the get() method in your own class
function setHeader($filename, $filesize)
{
// disable caching
$now = gmdate("D, d M Y H:i:s");
header("Expires: Tue, 01 Jan 2001 00:00:01 GMT");
header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
header("Last-Modified: {$now} GMT");
// force download
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header('Content-Type: text/x-csv');
// disposition / encoding on response body
if (isset($filename) && strlen($filename) > 0)
header("Content-Disposition: attachment;filename={$filename}");
if (isset($filesize))
header("Content-Length: ".$filesize);
header("Content-Transfer-Encoding: binary");
header("Connection: close");

With Bootstrap 3, you can use the 'text-center' styling attribute.
<div class="col-md-3 text-center">
<button id="button" name="button" class="btn btn-primary">Press Me!</button>
</div>
You can always access child views via View.findViewById() http://developer.android.com/reference/android/view/View.html#findViewById(int).
For example, within an activity / view:
...
private void init() {
View child1 = findViewById(R.id.child1);
}
...
or if you have a reference to a view:
...
private void init(View root) {
View child2 = root.findViewById(R.id.child2);

This happens every time you insert/ update and you don't use single quotes. When the variable is empty it will result in that error. Fix it by using ''
Assuming the first parameter is an empty variable here is a simple example:
Wrong
nvl( ,0)
Fix
nvl('' ,0)
Put your query into your database software and check it for that error. Generally this is an easy fix
Kindly use below code in header section your index file.

You can also achieve this using a CSS Grids framework, such as YUI Grids or Blue Print CSS. They solve alot of the cross browser issues and make more sophisticated column layouts possible for use mere mortals.
I find this helpful:
function console($data, $priority, $debug)
{
if ($priority <= $debug)
{
$output = '<script>console.log("' . str_repeat(" ", $priority-1) . (is_array($data) ? implode(",", $data) : $data) . '");</script>';
echo $output;
}
}
And use it like:
<?php
$debug = 5; // All lower and equal priority logs will be displayed
console('Important', 1 , $debug);
console('Less Important', 2 , $debug);
console('Even Less Important', 5 , $debug);
console('Again Important', 1 , $debug);
?>
Which outputs in console:
Important Less Important Even Less Important Again Important
And you can switch off less important logs by limiting them using the $debug value.
DP size of any device is (actual resolution / density conversion factor).
Density conversion factor for density buckets are as follows:
ldpi: 0.75
mdpi: 1.0 (base density)
hdpi: 1.5
xhdpi: 2.0
xxhdpi: 3.0
xxxhdpi: 4.0
Examples of resolution/density conversion to DP:
ldpi device of 240 X 320 px will be of 320 X 426.66 DP. 240 / 0.75 = 320 dp 320 / 0.75 = 426.66 dp
xxhdpi device of 1080 x 1920 pixels (Samsung S4, S5) will be of 360 X 640 dp. 1080 / 3 = 360 dp 1920 / 3 = 640 dp

These answers are overly complicated. You can change the main body font size (as well as any other CSS you might want to change) simply by embedding CSS directly into the Rmarkdown document using the html <style>
tag. You do not need an entire CSS file for something so simple. If you are doing a lot of CSS then use a separate CSS file. If you are just modifying a couple of simple things I would do it like this.

Note that what you want is to know if stdin is connected to a terminal or not, not if it exists. It always exists but when you use the shell to pipe something into it or read a file, it is not connected to a terminal.
You can check that a file descriptor is connected to a terminal via the termios.h functions:
#include <termios.h>
#include <stdbool.h>
bool stdin_is_a_pipe(void)
{
struct termios t;
return (tcgetattr(STDIN_FILENO, &t) < 0);
}
This will try to fetch the terminal attributes of stdin. If it is not connected to a pipe, it is attached to a tty and the tcgetattr function call will succeed. In order to detect a pipe, we check for tcgetattr failure.
For MSSQL, there are two ways:(Consider you have a 'users' table,below both examples are using this table for example)
1) In case, you need to insert different values in users table. Then you can write statement like:
INSERT INTO USERS VALUES
(2, 'Michael', 'Blythe'),
(3, 'Linda', 'Mitchell'),
(4, 'Jillian', 'Carson'),
(5, 'Garrett', 'Vargas');
2) Another case, if you need to insert same value for all rows(for example, 10 rows you need to insert here). Then you can use below sample statement:
INSERT INTO USERS VALUES
(2, 'Michael', 'Blythe')
GO 10
Hope this helps.
If you need a function that behaves as a nop, try
nop = lambda *a, **k: None
nop()
Sometimes I do stuff like this when I'm making dependencies optional:
try:
import foo
bar=foo.bar
baz=foo.baz
except:
bar=nop
baz=nop
# Doesn't break when foo is missing:
bar()
baz()
EDIT:
As pointed out in the comments, this is a much simpler version:
Arrays.stream(stringArray).mapToInt(Integer::parseInt).toArray()
This way we can skip the whole conversion to and from a list.
I found another one line solution, but it's still pretty slow (takes about 100 times longer than a for cycle - tested on an array of 6000 0's)
String[] stringArray = ...
int[] out= Arrays.asList(stringArray).stream().map(Integer::parseInt).mapToInt(i->i).toArray();

I think you should use the Rails debug options:
logger.debug "Person attributes hash: #{@person.attributes.inspect}"
logger.info "Processing the request..."
logger.fatal "Terminating application, raised unrecoverable error!!!"

This is a general error, which throws sometimes, when you have mismatch between the types of the data you use. E.g I tried to resize the image with opencv, it gave the same error. Here is a discussion about it.
When you start the container, you will be root but you won't know what root's pw is. To set it to something you know simply use "passwd root". Snapshot/commit the container to save your actions.
According to many c compilers:
<<
is an arithmetic left shift or bitwise left shift.>>
is an arithmetic right shiftor bitwise right shift.$ git clone --no-hardlinks /path/to/repo
The above command uses POSIX path notation for the directory with your git repository. For Windows it is (directory C:/path/to/repo
contains .git
directory):
C:\some\dir\> git clone --local file:///C:/path/to/repo my_project
The repository will be clone to C:\some\dir\my_project
. If you omit file:///
part then --local
option is implied.
Assuming that you have a DHCP server running at your router I would use:
# /etc/network/interfaces
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
After changing the file issue (as root):
/etc/init.d/networking restart
Here is the PowerShell script using msiexec:
echo "Getting product code"
$ProductCode = Get-WmiObject win32_product -Filter "Name='Name of my Software in Add Remove Program Window'" | Select-Object -Expand IdentifyingNumber
echo "removing Product"
# Out-Null argument is just for keeping the power shell command window waiting for msiexec command to finish else it moves to execute the next echo command
& msiexec /x $ProductCode | Out-Null
echo "uninstallation finished"
While M$ "best practices" is to not write data into the %programfiles% folder; I sometimes do. I do not think it wise to write temporary files into such a folder; as the TEMP environment variable might e.g. point to a nice, fast, RAM drive.
I do not like to write data into %APPDATA% however. If windows gets so badly messed up that one needs to e.g. wipe it and reinstall totally, perhaps to a different drive, you might lose all your settings for nearly all your programs. I know. I've done it many times. If it is stored in %programfiles%, 1) it doesn't get lost if I e.g. have to re-install Windows on another drive, since a user can simply run the program from its directory, 2) it makes it portable, and 3) keeps programs and their data files together.
I got write access by having my installer, Inno Setup, create an empty file for my INI file, and gave it the users-modify setting in the [Files] section. I can now write it at will.
Also the scope is different between viewbag and temptdata. viewbag is based on first view (not shared between action methods) but temptdata can be shared between an action method and just one another.
If you are using angular-cli

You can configure HttpClient
to automatically pass credentials like this:
var myClient = new HttpClient(new HttpClientHandler() { UseDefaultCredentials = true });
Its very simple:
For ObjC:
NSString *string1 = @"This is";
NSString *string2 = @"Swift Language";
ForSwift:
let string1 = "This is"
let string2 = "Swift Language"
For ObjC AppendString:
NSString *appendString=[NSString stringWithFormat:@"%@ %@",string1,string2];
For Swift AppendString:
var appendString1 = "\(string1) \(string2)"
var appendString2 = string1+string2
Result:
print("APPEND STRING 1:\(appendString1)")
print("APPEND STRING 2:\(appendString2)")
Complete Code In Swift:
let string1 = "This is"
let string2 = "Swift Language"
var appendString = "\(string1) \(string2)"
var appendString1 = string1+string2
print("APPEND STRING1:\(appendString1)")
print("APPEND STRING2:\(appendString2)")
The function name does not reflect the semantic of the function. In fact you do not append a character. You create a new character array that contains the original array plus the given character. So if you indeed need a function that appends a character to a character array I would write it the following way
bool AppendCharToCharArray( char *array, size_t n, char c )
{
size_t sz = std::strlen( array );
if ( sz + 1 < n )
{
array[sz] = c;
array[sz + 1] = '\0';
}
return ( sz + 1 < n );
}
If you need a function that will contain a copy of the original array plus the given character then it could look the following way
char * CharArrayPlusChar( const char *array, char c )
{
size_t sz = std::strlen( array );
char *s = new char[sz + 2];
std::strcpy( s, array );
s[sz] = c;
s[sz + 1] = '\0';
return ( s );
}
This may be of help to a few who are struggling like I was:
var data = myform.getRange("A:AA").getValues().pop();
var myvariable1 = data[4];
var myvariable2 = data[7];
<select class="dropdownmenu" name="drop-down">
<option class="dropdownmenu_list1" value="select-option">Choose ...</option>
<option class="dropdownmenu_list2" value="Topic 1">Option 1</option>
<option class="dropdownmenu_list3" value="Topic 2">Option 2</option>
</select>
This works best in Firefox. Too bad that Chrome and Safari do not support this rather easy CSS styling.
Need to set the foreign key option as on delete cascade... in tables which contains foreign key columns.... It need to set at the time of table creation or add later using ALTER table
File name should match the layout id which in this example is : items_list_item.xml in the layout folder of your application
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<ImageView android:id="@+id/R.id.list_item_image"

android:layout_height="wrap_content" />
</LinearLayout>

PHP syntax is little different in case of concatenation from JavaScript.
Instead of (+) plus
a (.) period
is used for string concatenation.
<?php
$selectBox = '<select name="number">';
for ($i=1;$i<=100;$i++)
{
$selectBox += '<option value="' . $i . '">' . $i . '</option>'; // <-- (Wrong) Replace + with .
$selectBox .= '<option value="' . $i . '">' . $i . '</option>'; // <-- (Correct) Here + is replaced .
}
$selectBox += '</select>'; // <-- (Wrong) Replace + with .
$selectBox .= '</select>'; // <-- (Correct) Here + is replaced .
echo $selectBox;

You need to use the square brackets notation to have values sent as an array:
<form method='post' id='userform' action='thisform.php'>
<tr>
<td>Trouble Type</td>
<td>
<input type='checkbox' name='checkboxvar[]' value='Option One'>1<br>
<input type='checkbox' name='checkboxvar[]' value='Option Two'>2<br>
<input type='checkbox' name='checkboxvar[]' value='Option Three'>3
</td>
</tr>
</table>
<input type='submit' class='buttons'>
</form>
Please note though, that only the values of only checked checkboxes will be sent.
Here's another one-liner approach to throw out there:
next((some_list.pop(i) for i, l in enumerate(some_list) if l == thing), None)
It doesn't create a list copy, doesn't make multiple passes through the list, doesn't require additional exception handling, and returns the matched object or None if there isn't a match. Only issue is that it makes for a long statement.
In general, when looking for a one-liner solution that doesn't throw exceptions, next() is the way to go, since it's one of the few Python functions that supports a default argument.
// The answer that I was looking for when searching
public void Answer()
{
IEnumerable<YourClass> first = this.GetFirstIEnumerableList();
// Assign to empty list so we can use later
IEnumerable<YourClass> second = new List<YourClass>();
if (IwantToUseSecondList)
{
second = this.GetSecondIEnumerableList();
}
IEnumerable<SchemapassgruppData> concatedList = first.Concat(second);
}
Since I think you are new with Python, lets do the long way, iterate thru your list using for loop and multiply and append each element to a new list.
using for loop
lst = [5, 20 ,15]
product = []
for i in lst:
product.append(i*5)
print product
using list comprehension, this is also same as using for-loop but more 'pythonic'
lst = [5, 20 ,15]
prod = [i * 5 for i in lst]
print prod

tl;dr version: Make sure you are not trying to open a file marked in the file system as Read-Only in Read/Write mode.
I have come across this error in my travels trying to read in an XML file. I have found that in some circumstances (detailed below) this error would be generated for a file even though the path and file name are correct.
File details:
When trying to read the file programmatically, the following behavior was observed while running the exact same code:
In order to fix this, I had to change the method call from the default (Opening as RW) to opening the file as RO. Once I made that one change, it stopped throwing an error.
# To support matches from the beginning, not any matches:
items = ['a', 'ab', 'abc', 'bac']
prefix = 'ab'

Unable to find local Grunt
likely means that you have installed Grunt globally.
The Grunt CLI insists that you install grunt in your local node_modules directory, so Grunt is local to your project.
This will fail:
npm install -g grunt
Do this instead:
npm install grunt --save-dev

The Simulator does not run ARM code, ONLY x86 code. Unless you have the raw source code from Apple, you won't see the App Store on the Simulator.
The app you write you will be able to test in the Simulator by running it directly from Xcode even if you don't have a developer account. To test your app on an actual device, you will need to be apart of the Apple Developer program.
Using aggregate function like below :
[
{$group: {_id : {book : '$book',address:'$addr'}, total:{$sum :1}}},
{$project : {book : '$_id.book', address : '$_id.address', total : '$total', _id : 0}}
]
it will give you result like following :
{
"total" : 1,
"book" : "book33",
"address" : "address90"
},
{
"total" : 1,
"book" : "book5",
"address" : "address1"
},
{
"total" : 1,
"book" : "book99",
"address" : "address9"
},
{
"total" : 1,
"book" : "book1",
"address" : "address5"
},
{
"total" : 1,
"book" : "book5",
"address" : "address2"
},
{
"total" : 1,
"book" : "book3",
"address" : "address4"
},
{
"total" : 1,
"book" : "book11",
"address" : "address77"
},
{
"total" : 1,
"book" : "book9",
"address" : "address3"
},
{
"total" : 1,
"book" : "book1",
"address" : "address15"
},
{

"book" : "book1",
"address" : "address2"
},
{
"total" : 3,
"book" : "book1",
"address" : "address1"
}
I didn't quite get your expected result format, so feel free to modify this to one you need.

Awkward I know.
best and simple way to use native java Script which is one liner code.
document.querySelector('#id').click();
Just add 'id' to your html element like
<button id="myId1" ng-click="someFunction()"></button>
check condition in javascript code
if(condition) {
document.querySelector('#myId1').click();
}
You can use like this.
when: condition1 == "condition1" or condition2 == "condition2"

Some good answers here but just adding an approach that won't be affected by borders and padding:
<style type="text/css">
html, body{width: 100%; height: 100%; padding: 0; margin: 0}
div{position: absolute; padding: 1em; border: 1px solid #000}
#nw{background: #f09; top: 0; left: 0; right: 50%; bottom: 50%}
#ne{background: #f90; top: 0; left: 50%; right: 0; bottom: 50%}
#sw{background: #009; top: 50%; left: 0; right: 50%; bottom: 0}
#se{background: #090; top: 50%; left: 50%; right: 0; bottom: 0}
</style>
<div id="nw">test</div>
<div id="ne">test</div>
<div id="sw">test</div>
<div id="se">test</div>
I assume that you have a .cer file containing PKCS#7-encoded certificate data and you want to convert it to PEM-encoded certificate data (typically a .crt or .pem file). For instance, a .cer file containing PKCS#7-encoded data looks like this:
-----BEGIN PKCS7----- MIIW4gYJKoZIhvcNAQcCoIIW0zCCFs8CAQExADALBgkqhkiG9w0BBwGggha1MIIH ... POI9n9cd2cNgQ4xYDiKWL2KjLB+6rQXvqzJ4h6BUcxm1XAX5Uj5tLUUL9wqT6u0G +bKhADEA -----END PKCS7-----
PEM certificate data looks like this:
-----BEGIN CERTIFICATE----- MIIHNjCCBh6gAwIBAgIQAlBxtqKazsxUSR9QdWWxaDANBgkqhkiG9w0BAQUFADBm ... nv72c/OV4nlyrvBLPoaS5JFUJvFUG8RfAEY= -----END CERTIFICATE-----
There is an OpenSSL command that will convert .cer files (with PKCS#7 data) to the PEM data you may be expecting to encounter (the BEGIN CERTIFICATE
block in the example above). You can coerce PKCS#7 data into PEM format by this command on a file we'll call certfile.cer:
openssl pkcs7 -text -in certfile.cer -print_certs -outform PEM -out certfile.pem
Note that a .cer or .pem file might contain one or more certificates (possibly the entire certificate chain).
You can declare an object of a class in another Class,that's possible but you cant initialize that object. For that you need to do something like this :--> (inside main)
Orderbook o1;
o1.m.check(side)
but that would be unnecessary. Keeping things short :-
You can't call functions inside a Class
extension UITapGestureRecognizer {
func didTapAttributedTextInLabel(label: UILabel, inRange targetRange: NSRange) -> Bool {
let layoutManager = NSLayoutManager()
let textContainer = NSTextContainer(size: CGSize.zero)
let textStorage = NSTextStorage(attributedString: label.attributedText!)
// Configure layoutManager and textStorage
layoutManager.addTextContainer(textContainer)
textStorage.addLayoutManager(layoutManager)
// Configure textContainer
textContainer.lineFragmentPadding = 0.0
textContainer.lineBreakMode = label.lineBreakMode
textContainer.maximumNumberOfLines = label.numberOfLines
textContainer.size = label.bounds.size
// main code
let locationOfTouchInLabel = self.location(in: label)
let indexOfCharacter = layoutManager.characterIndex(for: locationOfTouchInLabel, in: textContainer, fractionOfDistanceBetweenInsertionPoints: nil)
let indexOfCharacterRange = NSRange(location: indexOfCharacter, length: 1)
let indexOfCharacterRect = layoutManager.boundingRect(forGlyphRange: indexOfCharacterRange, in: textContainer)
let deltaOffsetCharacter = indexOfCharacterRect.origin.x + indexOfCharacterRect.size.width
if locationOfTouchInLabel.x > deltaOffsetCharacter {
return false
} else {
return NSLocationInRange(indexOfCharacter, targetRange)
}
}
}
The JSONArray.length() returns the number of elements in the JSONObject contained in the Array. Not the size of the array itself.
"filter" and "indexOf" aren't supported on Array in IE. How about this:
var array1 = [1, 2, 3];
var array2 = [2, 3, 4, 5];
var intersection = [];
for (i in array1) {
for (j in array2) {
if (array1[i] == array2[j]) intersection.push(array1[i]);
}
}
Above things are really helpful.
While creating web services, If you will take case of services consumer will greatly appreciated. I tried to maintain uniformity of the output. Also you can give remark or actual error message. The web service consumer can only check IsSuccess true or not else will sure there is problem, and act as per situation.

A JavaScript Date has several methods allowing you to extract its parts:
getFullYear()
- Returns the 4-digit year
getMonth()
- Returns a zero-based integer (0-11) representing the month of the year.
getDate()
- Returns the day of the month (1-31).
getDay()
- Returns the day of the week (0-6). 0 is Sunday, 6 is Saturday.
getHours()

There are no built-in methods allowing you to get localized strings like "Friday", "February", or "PM". You have to code that yourself. To get the string you want, you at least need to store string representations of days and months:
var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
var days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
Then, put it together using the methods above:
var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];_x000D_
var days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];_x000D_
var d = new Date();_x000D_
var day = days[d.getDay()];_x000D_
var hr = d.getHours();_x000D_
var min = d.getMinutes();_x000D_
if (min < 10) {_x000D_
min = "0" + min;_x000D_
}_x000D_
var ampm = "am";_x000D_
if( hr > 12 ) {_x000D_
hr -= 12;_x000D_
ampm = "pm";_x000D_
}_x000D_
var date = d.getDate();_x000D_
var month = months[d.getMonth()];_x000D_
var year = d.getFullYear();_x000D_
var x = document.getElementById("time");_x000D_
x.innerHTML = day + " " + hr + ":" + min + ampm + " " + date + " " + month + " " + year;
_x000D_
<span id="time"></span>
_x000D_
I have a date format function I like to include in my standard library. It takes a format string parameter that defines the desired output. The format strings are loosely based on .Net custom Date and Time format strings. For the format you specified the following format string would work: "dddd h:mmtt d MMM yyyy"
.
var d = new Date();
var x = document.getElementById("time");
x.innerHTML = formatDate(d, "dddd h:mmtt d MMM yyyy");

Here is my full date formatting function:
function formatDate(date, format, utc) {
var MMMM = ["\x00", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
var MMM = ["\x01", "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];

while (s.length < len) s = "0" + s;
return s;

Create a class like this:
public class Data
{
public string Id {get; set;}
public string Name {get; set;}
public string First_Name {get; set;}
public string Last_Name {get; set;}
public string Username {get; set;}
public string Gender {get; set;}
public string Locale {get; set;}
}
(I'm not 100% sure, but if that doesn't work you'll need use [DataContract]
and [DataMember]
for DataContractJsonSerializer
.)
Then create JSonSerializer
:
private static readonly XmlObjectSerializer Serializer = new DataContractJsonSerializer(typeof(Data));
and deserialize object:
// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
using(var stream = new MemoryStream(byteArray))
{
(Data)Serializer.ReadObject(stream);
}
Yes, you'll need to set Copy Local
to true
. However, I'm pretty sure you'll also need to reference that assembly from the main project and set Copy Local
to true
as well - it doesn't just get copied from a dependent assembly.
You can get to the Copy Local
property by clicking on the assembly under References
and pressing F4.
The href is a required attribute of an anchor element, so without it, you cannot expect all browsers to handle it equally. Anyway, I read somewhere in a comment that you only want the link to be underlined when hovering, and not otherwise. You can use the following to achieve this, and it will only apply to links with the hover-class:
<a class="hover" href="">click</a>
a.hover {
text-decoration: none;
}
a.hover:hover {
text-decoration:underline;
}
the best way for me :
$data=[
'var1'=>'something',
'var2'=>'something',
'var3'=>'something',
];
return View::make('view',$data);
NodeJS supports http.request as a standard module: http://nodejs.org/docs/v0.4.11/api/http.html#http.request
var http = require('http');
var options = {
host: 'example.com',
port: 80,
path: '/foo.html'
};
http.get(options, function(resp){
resp.on('data', function(chunk){
//do something with chunk
});
}).on("error", function(e){
console.log("Got error: " + e.message);
});
You could try always sending the first 4 bytes of your data as data size and then read complete data in one shot. Use the below functions on both client and server-side to send and receive data.
def send_data(conn, data):
serialized_data = pickle.dumps(data)
conn.sendall(struct.pack('>I', len(serialized_data)))
conn.sendall(serialized_data)
def receive_data(conn):
data_size = struct.unpack('>I', conn.recv(4))[0]
received_payload = b""
reamining_payload_size = data_size
while reamining_payload_size != 0:
received_payload += conn.recv(reamining_payload_size)
reamining_payload_size = data_size - len(received_payload)
data = pickle.loads(received_payload)
return data
you could find sample program at https://github.com/vijendra1125/Python-Socket-Programming.git
Here is just a way to simulate multi-threading in Javascript
Now I am going to create 3 threads which will calculate numbers addition, numbers can be divided with 13 and numbers can be divided with 3 till 10000000000. And these 3 functions are not able to run in same time as what Concurrency means. But I will show you a trick that will make these functions run recursively in the same time : jsFiddle
This code belongs to me.
Body Part
<div class="div1">
<input type="button" value="start/stop" onclick="_thread1.control ? _thread1.stop() : _thread1.start();" /><span>Counting summation of numbers till 10000000000</span> = <span id="1">0</span>
</div>
<div class="div2">
<input type="button" value="start/stop" onclick="_thread2.control ? _thread2.stop() : _thread2.start();" /><span>Counting numbers can be divided with 13 till 10000000000</span> = <span id="2">0</span>
</div>
<div class="div3">
<input type="button" value="start/stop" onclick="_thread3.control ? _thread3.stop() : _thread3.start();" /><span>Counting numbers can be divided with 3 till 10000000000</span> = <span id="3">0</span>
</div>
Javascript Part
var _thread1 = {//This is my thread as object
control: false,//this is my control that will be used for start stop
value: 0, //stores my result
current: 0, //stores current number
func: function () { //this is my func that will run
if (this.control) { // checking for control to run
if (this.current < 10000000000) {
this.value += this.current;
document.getElementById("1").innerHTML = this.value;
this.current++;
}
}
setTimeout(function () { // And here is the trick! setTimeout is a king that will help us simulate threading in javascript
_thread1.func(); //You cannot use this.func() just try to call with your object name
}, 0);
},
start: function () {
this.control = true; //start function
},
stop: function () {
this.control = false; //stop function
},
init: function () {
setTimeout(function () {
_thread1.func(); // the first call of our thread
}, 0)
}
};
var _thread2 = {
control: false,
value: 0,
current: 0,
func: function () {
if (this.control) {
if (this.current % 13 == 0) {
this.value++;
}
this.current++;
document.getElementById("2").innerHTML = this.value;
}
setTimeout(function () {
_thread2.func();
}, 0);
},
start: function () {
this.control = true;
},
stop: function () {
this.control = false;
},
init: function () {
setTimeout(function () {
_thread2.func();
}, 0)
}
};
var _thread3 = {
control: false,
value: 0,
current: 0,
func: function () {
if (this.control) {
if (this.current % 3 == 0) {
this.value++;
}
this.current++;
document.getElementById("3").innerHTML = this.value;
}
setTimeout(function () {
_thread3.func();
}, 0);
},
start: function () {
this.control = true;
},
stop: function () {
this.control = false;
},
init: function () {
setTimeout(function () {
_thread3.func();
}, 0)
}
};
_thread1.init();
_thread2.init();
_thread3.init();
I hope this way will be helpful.
In the nav go View => Layout => Columns:2
(alt+shift+2
) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py
)
It appears you can also reopen the file using the command File -> New View into File
which will open the current file in a new tab
There's a strong culture of tuples being for heterogeneous collections, similar to what you'd use struct
s for in C, and lists being for homogeneous collections, similar to what you'd use arrays for. But I've never quite squared this with the mutability issue mentioned in the other answers. Mutability has teeth to it (you actually can't change a tuple), while homogeneity is not enforced, and so seems to be a much less interesting distinction.
Also make sure that account is not locked out in user properties "Status" tab
