Go 1.11 will have a feature called go modules and you can simply add a dependency with a version. Follow these steps:
go mod init .
go mod edit -require github.com/wilk/[email protected]
go get -v -t ./...
go build
go install
Here's more info on that topic - https://github.com/golang/go/wiki/Modules
jQuery.i18n is a lightweight jQuery plugin for enabling internationalization in your web pages. It allows you to package custom resource strings in ‘.properties’ files, just like in Java Resource Bundles. It loads and parses resource bundles (.properties) based on provided language or language reported by browser.
to know more about this take a look at the How to internationalize your pages using JQuery?
A simple alternative to using a custom UserType is to construct a new java.util.Date in the setter for the date property in your persisted bean, eg:
import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.Column;
@Entity
public class Purchase {
private Date date;
@Column
public Date getDate() {
return this.date;
}
public void setDate(Date date) {
// force java.sql.Timestamp to be set as a java.util.Date
this.date = new Date(date.getTime());
}
}
What happens with bittorrent and a DHT is that at the beginning bittorrent uses information embedded in the torrent file to go to either a tracker or one of a set of nodes from the DHT. Then once it finds one node, it can continue to find others and persist using the DHT without needing a centralized tracker to maintain it.
The original information bootstraps the later use of the DHT.
Use a 1 by 1 GridLayout on the existing JPanel, then add your Panel to that JPanel. The only problem with a GridLayout that's 1 by 1 is that you won't be able to place other items on the JPanel. In this case, you will have to figure out a layout that is suitable. Each panel that you use can use their own layout so that wouldn't be a problem.
Am I understanding this question correctly?
I find it useful when including or requiring _dbconnection.php_
and _functions.php
in files that are actually processed, rather than including in the header. Which is included in itself.
So if your header and footer is included, simply include all your functional files before the header is included.
I know a lot of people have recommended PDF Sharp, however it doesn't look like that project has been updated since june of 2008. Further, source isn't available.
Personally, I've been playing with iTextSharp which has been pretty easy to work with.
setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").
From the command line, you can type
python setup.py --help
...to get a list of commands. What you are looking to do is...
python setup.py install
Perform a hard reboot of your phone. The easiest way to do this is to remove the phone's battery. Wait for at least 30 seconds, then replace the battery. The phone will reboot, and upon completing its restart will have an empty DNS cache.

I find list comprehensions are generally more expressive of what I'm trying to do than map
- they both get it done, but the former saves the mental load of trying to understand what could be a complex lambda
expression.
There's also an interview out there somewhere (I can't find it offhand) where Guido lists lambda
s and the functional functions as the thing he most regrets about accepting into Python, so you could make the argument that they're un-Pythonic by virtue of that.
Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.
Let me explain using step-by-step guidance.
First, download the source code from https://github.com/rmtheis/tess-two.
Import all three projects. After importing you will get an error.
To solve the error you have to create a res
folder in the tess-two project
First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"
After doing this in all three project the error should be gone.
Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.
Now you just need to import it into your workspace, but first you have to download android-ndk from this site:
http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file
Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable
Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture
done it
Now open cmd and go to on D:\Android Workspace\tess-two like below
If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:
Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest
Import test-two in this and run OCRTest and run it; you will get the best example of OCR.
This is happening because your PHP code is getting executed before the form gets posted.
To avoid this wrap your PHP code in following if statement and it will handle the rest no need to set if statements for each variables
if(isset($_POST) && array_key_exists('name_of_your_submit_input',$_POST))
{
//process PHP Code
}
else
{
//do nothing
}
The method array.toString()
actually calls array.join()
which result in a string concatenated by commas. ref
var array = ['a','b','c','d','e','f'];_x000D_
document.write(array.toString()); // "a,b,c,d,e,f"
_x000D_
Also, you can implicitly call Array.toString()
by making javascript coerce the Array
to an string
, like:
//will implicitly call array.toString()
str = ""+array;
str = `${array}`;
The join() method joins all elements of an array into a string.
It accepts a separator
as argument, but the default is already a comma ,
str = arr.join([separator = ','])
var array = ['A', 'B', 'C'];
var myVar1 = array.join(); // 'A,B,C'
var myVar2 = array.join(', '); // 'A, B, C'
var myVar3 = array.join(' + '); // 'A + B + C'
var myVar4 = array.join(''); // 'ABC'
If any element of the array is undefined or null , it is treated as an empty string.
It is available pretty much everywhere today, since IE 5.5 (1999~2000).
As Integer.toHexString(byte/integer) is not working when you are trying to convert signed bytes like UTF-16 decoded characters you have to use:
Integer.toString(byte/integer, 16);
or
String.format("%02X", byte/integer);
reverse you can use
Integer.parseInt(hexString, 16);
Hardware wise the Quadro and GeForce cards are often idential. Indeed it is sometimes possible to convert some models from GeForce into Quadro by simply uploading new firmware and changing a couple resistor jumpers.
The difference is in the intended market and hence cost.
Quadro cards are intended for CAD. High end CAD software still uses OpenGL, whereas games and lower end CAD software use Direct3D (aka DirectX).
Quadro cards simply have firmware that is optimised for OpenGL. In the early days OpenGL was better and faster than Direct3D but now there is little difference. Gaming cards only support a very limited set of OpenGL, hence they don't run it very well.
CAD companies, e.g. Dassault with SolidWorks actively push high end cards by offering no support for DirectX with any level of performance.
Other CAD companies such as Altium, with Altium Designer, made the decision that forcing their customers to buy more expensive cards is not worthwhile when Direct3D is as good (if not better these days) than OpenGL.
Because of the cost, there are often other differences in the hardware, such as less use of overclocking, more memory etc, but these have relatively minor effects compared with the firmware support.
try:
whatever()
except:
# this will catch any exception or error
It is worth mentioning this is not proper Python coding. This will catch also many errors you might not want to catch.
Check your build types of each project under project properties - I bet one or the other will be set to build against .NET XX - Client Profile
.
With inconsistent versions, specifically with one being Client Profile
and the other not, then it works at design time but fails at compile time. A real gotcha.
There is something funny going on in Visual Studio 2010 for me, which keeps setting projects seemingly randomly to Client Profile
, sometimes when I create a project, and sometimes a few days later. Probably some keyboard shortcut I'm accidentally hitting...
Solution above will work (make the url unique by adding in the querystring a new param) but I prefer the solution propose [here]: Better Way to Prevent IE Cache in AngularJS?, which handle this at server level as it's not specific to IE. I mean, if that resource should not be cached, do it on the server (this as nothing to do with the browser used; it's intrisic to the resource).
For example in java with JAX-RS do it programatically for JAX-RS v1 or declativly for JAX-RS v2.
I'm sure anyone will figure out how to do it
Given the following tables..
Domain Table
dom_id | dom_url
Review Table
rev_id | rev_dom_from | rev_dom_for
Try this sql... (It's pretty much the same thing that Stephen Wrighton wrote above) The trick is that you are basically selecting from the domain table twice in the same query and joining the results.
Select d1.dom_url, d2.dom_id from
review r, domain d1, domain d2
where d1.dom_id = r.rev_dom_from
and d2.dom_id = r.rev_dom_for
If you are still stuck, please be more specific with exactly it is that you don't understand.
Check the pointer for NULL
and then using strlen
to see if it returns 0
.
NULL
check is important because passing NULL
pointer to strlen
invokes an Undefined Behavior.
Here's a quick and dirty ctypes tutorial.
First, write your C library. Here's a simple Hello world example:
#include <stdio.h>
void myprint(void);
void myprint()
{
printf("hello world\n");
}
Now compile it as a shared library (mac fix found here):
$ gcc -shared -Wl,-soname,testlib -o testlib.so -fPIC testlib.c
# or... for Mac OS X
$ gcc -shared -Wl,-install_name,testlib.so -o testlib.so -fPIC testlib.c
Then, write a wrapper using ctypes:
import ctypes
testlib = ctypes.CDLL('/full/path/to/testlib.so')
testlib.myprint()
Now execute it:
$ python testlibwrapper.py
And you should see the output
Hello world
$
If you already have a library in mind, you can skip the non-python part of the tutorial. Make sure ctypes can find the library by putting it in /usr/lib
or another standard directory. If you do this, you don't need to specify the full path when writing the wrapper. If you choose not to do this, you must provide the full path of the library when calling ctypes.CDLL()
.
This isn't the place for a more comprehensive tutorial, but if you ask for help with specific problems on this site, I'm sure the community would help you out.
PS: I'm assuming you're on Linux because you've used ctypes.CDLL('libc.so.6')
. If you're on another OS, things might change a little bit (or quite a lot).
Use which.min
:
df <- data.frame(Name=c('A','B','C','D'), Amount=c(150,120,175,160))
df[which.min(df$Amount),]
> df[which.min(df$Amount),]
Name Amount
2 B 120

I ran into this problem on Windows 10 (N) with a new Anaconda installation based on Python 3.7 (OpenCV version 4.0). None of the above advice helped (such as installing OpenCV from the unofficial site nor installing VC Redistributable).
I checked DLL dependencies of ...\AppData\Local\conda\conda\envs\foo\Lib\site-packages\cv2\cv2.cp37-win_amd64.pyd
using dumpbin.exe
according to this github issue. I noticed a library MF.dll
, which I figured out belongs to Windows Media Foundation.
So I installed Media Feature Pack for N versions of Windows 10 and voilà, the issue was resolved!
I think it is matter of choice and context.I prefer to use
git log origin/master..origin/develop --oneline --no-merges
It will display commits in develop which are not in master branch.
If you want to see which files are actually modified use
git diff --stat origin/master..origin/develop --no-merges
If you don't specify arguments it will display the full diff.
If you want to see visual diff, install meld
on linux, or WinMerge
on windows. Make sure they are the default difftools .Then use something like
git difftool -y origin/master..origin/develop --no-merges
In case you want to compare it with current branch. It is more convenient to use HEAD instead of branch name like use:
git fetch
git log origin/master..HEAD --oneline --no-merges
It will show you all the commits, about to be merged
Require the JSON library, and use to_json
.
require 'json'
tempHash = {
"key_a" => "val_a",
"key_b" => "val_b"
}
File.open("public/temp.json","w") do |f|
f.write(tempHash.to_json)
end
Your temp.json file now looks like:
{"key_a":"val_a","key_b":"val_b"}

Whenever multiple values are returned from a function in python, does it always convert the multiple values to a list of multiple values and then returns it from the function??
I'm just adding a name and print the result that returns from the function. the type of result is 'tuple'.
class FigureOut:
first_name = None
last_name = None
def setName(self, name):
fullname = name.split()
self.first_name = fullname[0]
self.last_name = fullname[1]
self.special_name = fullname[2]
def getName(self):
return self.first_name, self.last_name, self.special_name
f = FigureOut()
f.setName("Allen Solly Jun")
name = f.getName()
print type(name)
I don't know whether you have heard about 'first class function'. Python is the language that has 'first class function'
I hope my answer could help you. Happy coding.
If you set up your file system differently or looking for a different way of setting up a file system and then checking if a file exists in the documents folder heres an another example. also show dynamic checking
for (int i = 0; i < numberHere; ++i){
NSFileManager* fileMgr = [NSFileManager defaultManager];
NSString *documentsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString* imageName = [NSString stringWithFormat:@"image-%@.png", i];

BOOL fileExists = [fileMgr fileExistsAtPath:currentFile];
if (fileExists == NO){
cout << "DOESNT Exist!" << endl;
} else {

1.2975118E7
is scientific notation.
1.2975118E7 = 1.2975118 * 10^7 = 12975118
Also, Math.round(f)
returns an integer. You can't use it to get your desired format x.xx
.
You could use String.format
.
String s = String.format("%.2f", 1.2975118);
// 1.30
I'm not saying that there's anything wrong with your question or the answer given, but maybe you'd like to know about the wonderful tool that is Hoogle to save yourself time in the future: With Hoogle, you can search for standard library functions that match a given signature. So, not knowing anything about !!
, in your case you might search for "something that takes an Int
and a list of whatevers and returns a single such whatever", namely
Int -> [a] -> a
Lo and behold, with !!
as the first result (although the type signature actually has the two arguments in reverse compared to what we searched for). Neat, huh?
Also, if your code relies on indexing (instead of consuming from the front of the list), lists may in fact not be the proper data structure. For O(1) index-based access there are more efficient alternatives, such as arrays or vectors.
You have to right idea generating the url based off of the input value. The only issue is you are using window.location.href. Setting window.location.href changes the url of the current window. What you probably want to do is change the src attribute of an image.
<html>
<body>
<form>
<input type="text" value="" id="imagename">
<input type="button" onclick="var image = document.getElementById('the-image'); image.src='http://webpage.com/images/'+document.getElementById('imagename').value +'.png'" value="GO">
</form>
<img id="the-image">
</body>
</html>
I think this is only partially true. Changing the format seems to switch the date to a string object which then has no methods like AddDays to manipulate it. So to make this work, you have to switch it back to a date. For example:
Get-Date (Get-Date).AddDays(-1) -format D
I had same issue and I solved it by "pod setup" after installing cocoapods.
This may help you find what you're looking for... Batch script loop
My answer is as follows:
@echo off
:start
set /a var+=1
if %var% EQU 100 goto end
:: Code you want to run goes here
goto start
:end
echo var has reached %var%.
pause
exit
The first set of commands under the start label loops until a variable, %var% reaches 100. Once this happens it will notify you and allow you to exit. This code can be adapted to your needs by changing the 100 to 17 and putting your code or using a call command followed by the batch file's path (Shift+Right Click on file and select "Copy as Path") where the comment is placed.
compare()
will return false
(well, 0
) if the strings are equal.
So don't take exchanging one for the other lightly.
Use whichever makes the code more readable.

The release is likely missing a library/plugin or the library is in the wrong directory and or from the wrong directory.
Qt intended answer: Use windeployqt. see last paragraph for explanation
Manual answer:
Create a folder named "platforms" in the same directory as your application.exe file. Copy and paste the qwindows.dll, found in the /bin of whichever compiler you used to release your application, into the "platforms" folder. Like magic it works. If the .dll is not there check plugins/platforms/ ( with plugins/ being in the same directory as bin/ ) <-- PfunnyGuy's comment.
It seems like a common issue is that the .dll was taken from the wrong compiler bin. Be sure to copy your the qwindows.dll from the same compiler as the one used to release your app.
Qt comes with platform console applications that will add all dependencies (including ones like qwindows.dll and libEGL.dll) into the folder of your deployed executable. This is the intended way to deploy your application, so you do not miss any libraries (which is the main issue with all of these answers). The application for windows is called windeployqt. There is likely a deployment console app for each OS.
Had the same problem,
All i had to do whas set the oracle shell variable:
. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh
Sorterd!
It really depends :) One of the handy linux core utils (info coreutils
) is xargs
. If you are using awk
you probably have a more involved use-case in mind - your question is not very detailled.
printf "1 2\n3 4" | awk '{ print $2 }' | xargs touch
Will execute touch 2 4
. Here touch
could be replaced by your program. More info at info xargs
and man xargs
(really, read these).
I believe you would like to replace touch
with your program.
Breakdown of beforementioned script:
printf "1 2\n3 4"
# Output:
1 2
3 4
# The pipe (|) makes the output of the left command the input of
# the right command (simplified)
printf "1 2\n3 4" | awk '{ print $2 }'
# Output (of the awk command):
2
4
# xargs will execute a command with arguments. The arguments
# are made up taking the input to xargs (in this case the output
# of the awk command, which is "2 4".
printf "1 2\n3 4" | awk '{ print $2 }' | xargs touch
# No output, but executes: `touch 2 4` which will create (or update
# timestamp if the files already exist) files with the name "2" and "4"
Update In the original answer, I used echo
instead of printf
. However, printf
is the better and more portable alternative as was pointed out by a comment (where great links with discussions can be found).
Although the second option is more general, the first option is better when you have an absolute tolerance, and when you have to execute many of these comparisons. If this comparison is say for every pixel in an image, the multiplication in the second options might slow your execution to unacceptable levels of performance.
the previous response is ASP.NET only
you need a reference to jquery (perhaps from a CDN): http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.1.js
and then a similar block of code but simpler...
$.ajax({ url: '/Controller/Action/Id',
success: function(data) { alert(data); },
statusCode : {
404: function(content) { alert('cannot find resource'); },
500: function(content) { alert('internal server error'); }
},
error: function(req, status, errorObj) {
// handle status === "timeout"
// handle other errors
}
});
I've added some necessary handlers, 404 and 500 happen all the time if you are debugging code. Also, a lot of other errors, such as timeout, will filter out through the error handler.
ASP.NET MVC Controllers handle requests, so you just need to request the correct URL and the controller will pick it up. This code sample with work in environments other than ASP.NET
For GlassFish Jersey JAX-RS implementation I have resolved this issue by common method is describing all common parameters. At least three of parameters have to be equal: name(="name"), path(="/") and domain(=null) :
public static NewCookie createDomainCookie(String value, int maxAgeInMinutes) {
ZonedDateTime time = ZonedDateTime.now().plusMinutes(maxAgeInMinutes);
Date expiry = time.toInstant().toEpochMilli();
NewCookie newCookie = new NewCookie("name", value, "/", null, Cookie.DEFAULT_VERSION,null, maxAgeInMinutes*60, expiry, false, false);
return newCookie;
}
And use it the common way to set cookie:
NewCookie domainNewCookie = RsCookieHelper.createDomainCookie(token, 60);
Response res = Response.status(Response.Status.OK).cookie(domainNewCookie).build();
and to delete the cookie:
NewCookie domainNewCookie = RsCookieHelper.createDomainCookie("", 0);
Response res = Response.status(Response.Status.OK).cookie(domainNewCookie).build();

Don't loop through a file this way. Instead use a for
loop.
for line in f:
vowel += sum(ch.isvowel() for ch in line)
In fact your whole program is just:
VOWELS = {'A','E','I','O','U','a','e','i','o','u'}
# I'm assuming this is what isvowel checks, unless you're doing something
# fancy to check if 'y' is a vowel
with open('filename.txt') as f:
vowel = sum(ch in VOWELS for line in f for ch in line.strip())
That said, if you really want to keep using a while
loop for some misguided reason:
while True:
line = f.readline().strip()
if line == '':
# either end of file or just a blank line.....
# we'll assume EOF, because we don't have a choice with the while loop!
break
Do you mean display resolution (eg 72 dots per inch) or pixel dimensions (browser window is currently 1000 x 800 pixels)?
Screen resolution enables you to know how thick a 10 pixel line will be in inches. Pixel dimensions tell you what percentage of the available screen height will be taken up by a 10 pixel wide horizontal line.
There's no way to know the display resolution just from Javascript since the computer itself usually doesn't know the actual dimensions of the screen, just the number of pixels. 72 dpi is the usual guess....
Note that there's a lot of confusion about display resolution, often people use the term instead of pixel resolution, but the two are quite different. See Wikipedia
Of course, you can also measure resolution in dots per cm. There is also the obscure subject of non-square dots. But I digress.
I don't think you can use braces.
According to the Bash manual about case in Conditional Constructs.
Each pattern undergoes tilde expansion, parameter expansion, command substitution, and arithmetic expansion.
Nothing about Brace Expansion unfortunately.
So you'd have to do something like this:
case $1 in
req*)
...
;;
met*|meet*)
...
;;
*)
# You should have a default one too.

MoreLinq has a DistinctBy method that you can use:
It will allow you to do:
var results = table1.DistictBy(row => row.Text);
The implementation of the method (short of argument validation) is as follows:
private static IEnumerable<TSource> DistinctByImpl<TSource, TKey>(IEnumerable<TSource> source,
Func<TSource, TKey> keySelector, IEqualityComparer<TKey> comparer)
{
HashSet<TKey> knownKeys = new HashSet<TKey>(comparer);
foreach (TSource element in source)
{
if (knownKeys.Add(keySelector(element)))
{
yield return element;
}
}
}
I've been also using SmartAssembly. I found that Ezrinz .Net Reactor much better for me on .net applications. It obfuscates, support Mono, merges assemblies and it also also has a very nice licensing module to create trial version or link the licence to a particular machine (very easy to implement). Price is also very competitive and when I needed support they where fast. Eziriz
Just to be clear I'm just a custumer who likes the product and not in any way related with the company.
You can try the following library: http://code.google.com/p/android-screenshot-library/ Android Screenshot Library (ASL) enables to programmatically capture screenshots from Android devices without requirement of having root access privileges. Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.
You can use MutationObserver to track attribute changes including data-*
changes. For example:
var foo = document.getElementById('foo');_x000D_
_x000D_
var observer = new MutationObserver(function(mutations) {_x000D_
console.log('data-select-content-val changed');_x000D_
});_x000D_
observer.observe(foo, { _x000D_
attributes: true, _x000D_
attributeFilter: ['data-select-content-val'] });_x000D_
_x000D_
foo.dataset.selectContentVal = 1;
_x000D_
<div id='foo'></div>_x000D_
_x000D_
I'll assume that Time
and Product
are columns in a DataFrame
, df
is an instance of DataFrame
, and that other variables are scalar values:
For now, you'll have to reference the DataFrame
instance:
k1 = df.loc[(df.Product == p_id) & (df.Time >= start_time) & (df.Time < end_time), ['Time', 'Product']]
The parentheses are also necessary, because of the precedence of the &
operator vs. the comparison operators. The &
operator is actually an overloaded bitwise operator which has the same precedence as arithmetic operators which in turn have a higher precedence than comparison operators.
In pandas
0.13 a new experimental DataFrame.query()
method will be available. It's extremely similar to subset modulo the select
argument:
With query()
you'd do it like this:
df[['Time', 'Product']].query('Product == p_id and Month < mn and Year == yr')
Here's a simple example:
In [9]: df = DataFrame({'gender': np.random.choice(['m', 'f'], size=10), 'price': poisson(100, size=10)})
In [10]: df
Out[10]:
gender price
0 m 89
1 f 123
2 f 100
3 m 104
4 m 98
5 m 103
6 f 100
7 f 109
8 f 95
9 m 87
In [11]: df.query('gender == "m" and price < 100')
Out[11]:
gender price
0 m 89
4 m 98
9 m 87
The final query that you're interested will even be able to take advantage of chained comparisons, like this:
k1 = df[['Time', 'Product']].query('Product == p_id and start_time <= Time < end_time')
Looking at the error message, Android Studio tried to install older version of apk (lets say 0.5.1) while current version is lets say 0.5.2. Android Studio builds 0.5.2 but tries to install 0.5.1 for some reason.
I have turned off Instant Run, invalidated and restarted, rebuilt project and didn't help.
Solution worked for me is to uninstall the app, then change the current branch on VCS to some other branch. Then come again to latest branch and Rebuilt, Install the APK again.
This is the way I do it. ISO format:
import datetime
datetime.datetime.now().replace(microsecond=0).isoformat()
# Returns: '2017-01-23T14:58:07'
You can replace the 'T' if you don't want ISO format:
datetime.datetime.now().replace(microsecond=0).isoformat(' ')
# Returns: '2017-01-23 15:05:27'
You cannot decrypt this password again but there is another method named "pwdcompare". Here is a example how to use it with SQL syntax:
USE TEMPDB
GO
declare @hash varbinary (255)
CREATE TABLE tempdb..h (id_num int, hash varbinary (255))
SET @hash = pwdencrypt('123') -- encryption
INSERT INTO tempdb..h (id_num,hash) VALUES (1,@hash)
SET @hash = pwdencrypt('123')
INSERT INTO tempdb..h (id_num,hash) VALUES (2,@hash)
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 2
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
INSERT INTO tempdb..h (id_num,hash)
VALUES (3,CONVERT(varbinary (255),
0x01002D60BA07FE612C8DE537DF3BFCFA49CD9968324481C1A8A8FE612C8DE537DF3BFCFA49CD9968324481C1A8A8))
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 3
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
DROP TABLE tempdb..h
GO
Editing or overriding the row in Twitter bootstrap is a bad idea, because this is a core part of the page scaffolding and you will need rows without a top margin.
To solve this, instead create a new class "top-buffer" that adds the standard margin that you need.
.top-buffer { margin-top:20px; }
And then use it on the row divs where you need a top margin.
<div class="row top-buffer"> ...
You could use replicate
or sapply
:
R> colMeans(replicate(10000, sample(100, size=815, replace=TRUE, prob=NULL))) R> sapply(seq_len(10000), function(...) mean(sample(100, size=815, replace=TRUE, prob=NULL)))
replicate
is a wrapper for the common use of sapply
for repeated evaluation of an expression (which will usually involve random number generation).
Object.assign will only work in single level of object reference.
To do a copy in any depth use as below:
let x = {'a':'a','b':{'c':'c'}};
let y = JSON.parse(JSON.stringify(x));
If want to use any library instead then go with the loadash.js
library.
The following regex matches alphanumeric characters and underscore:
^[a-zA-Z0-9_]+$
For example, in Perl:
#!/usr/bin/perl -w
my $arg1 = $ARGV[0];
# check that the string contains *only* one or more alphanumeric chars or underscores
if ($arg1 !~ /^[a-zA-Z0-9_]+$/) {
print "Failed.\n";
} else {
print "Success.\n";
}
Each numeric type has its own value. See TypeCode enum definition: https://docs.microsoft.com/en-us/dotnet/api/system.typecode?view=netframework-4.8 Based on this info, all your numeric type-values are in the range from 5 to 15. This means, you can write the condition-check like this:
$typeValue = $x.getTypeCode().value__
if ($typeValue -ge 5 -and $typeValue -le 15) {"x has a numeric type!"}
I would concatenate the old list and new list as streams and save the results to destination list. Works well in parallel, too.
I will use the example of accepted answer given by Stuart Marks:
List<String> destList = Arrays.asList("foo");
List<String> newList = Arrays.asList("0", "1", "2", "3", "4", "5");
destList = Stream.concat(destList.stream(), newList.stream()).parallel()
.collect(Collectors.toList());
System.out.println(destList);
//output: [foo, 0, 1, 2, 3, 4, 5]
Hope it helps.
As explained here, you can use:
function replaceall(str,replace,with_this)
{
var str_hasil ="";
var temp;
for(var i=0;i<str.length;i++) // not need to be equal. it causes the last change: undefined..
{
if (str[i] == replace)
{
temp = with_this;
}
else
{
temp = str[i];
}
str_hasil += temp;
}
return str_hasil;
}
... which you can then call using:
var str = "50.000.000";
alert(replaceall(str,'.',''));
The function will alert "50000000"
If you want to drop rows of data frame on the basis of some complicated condition on the column value then writing that in the way shown above can be complicated. I have the following simpler solution which always works. Let us assume that you want to drop the column with 'header' so get that column in a list first.
text_data = df['name'].tolist()
now apply some function on the every element of the list and put that in a panda series:
text_length = pd.Series([func(t) for t in text_data])
in my case I was just trying to get the number of tokens:
text_length = pd.Series([len(t.split()) for t in text_data])
now add one extra column with the above series in the data frame:
df = df.assign(text_length = text_length .values)
now we can apply condition on the new column such as:
df = df[df.text_length > 10]
def pass_filter(df, label, length, pass_type):
text_data = df[label].tolist()
text_length = pd.Series([len(t.split()) for t in text_data])
df = df.assign(text_length = text_length .values)
if pass_type == 'high':
df = df[df.text_length > length]
if pass_type == 'low':
df = df[df.text_length < length]
df = df.drop(columns=['text_length'])
return df
I fixed this by adding the following into MainApplication.onCreate
:
try {
PackageInfo info = getPackageManager().getPackageInfo(
"com.genolingo.genolingo",
PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String hash = Base64.encodeToString(md.digest(), Base64.DEFAULT);
KeyHash.addKeyHash(hash);
}
}
catch (PackageManager.NameNotFoundException e) {
Log.e("PackageInfoError:", "NameNotFoundException");
}
catch (NoSuchAlgorithmException e) {
Log.e("PackageInfoError:", "NoSuchAlgorithmException");
}
I then uploaded this to the Google developer console and then downloaded the derived APK which, for whatever reason, has a totally different key hash.
I then used LogCat to determine the new key hash and added it Facebook as other users have outlined.
Depending on how you render your view, you may also need:
@Bean
public StringHttpMessageConverter stringHttpMessageConverter() {
return new StringHttpMessageConverter(Charset.forName("UTF-8"));
}
<input type="number" step="any">
This worked for me and i think is the easiest way to make the input field accept any decimal number irrespective of how long the decimal part is. Step attribute actually shows the input field how many decimal points should be accepted. E.g, step="0.01" will accept only two decimal points.
var seconds = 0;
setInterval(function () {
seconds++;
}, 1000);
There you go, now you have a variable counting seconds elapsed. Since I don't know the context, you'll have to decide whether you want to attach that variable to an object or make it global.
Set interval is simply a function that takes a function as it's first parameter and a number of milliseconds to repeat the function as it's second parameter.
You could also solve this by saving and comparing times.
EDIT: This answer will provide very inconsistent results due to things such as the event loop and the way browsers may choose to pause or delay processing when a page is in a background tab. I strongly recommend using the accepted answer.
Note you can do something like this(at least in MVC3):
<td align="left" @(isOddRow ? "class=TopBorder" : "style=border:0px") >
What I believed was razor adding quotes was actually the browser. As Rism pointed out when testing with MVC 4(I haven't tested with MVC 3 but I assume behavior hasn't changed), this actually produces class=TopBorder
but browsers are able to parse this fine. The HTML parsers are somewhat forgiving on missing attribute quotes, but this can break if you have spaces or certain characters.
<td align="left" class="TopBorder" >
OR
<td align="left" style="border:0px" >
If you try to use some of the usual C# conventions for nested quotes, you'll end up with more quotes than you bargained for because Razor is trying to safely escape them. For example:
<button type="button" @(true ? "style=\"border:0px\"" : string.Empty)>
This should evaluate to <button type="button" style="border:0px">
but Razor escapes all output from C# and thus produces:
style="border:0px"
You will only see this if you view the response over the network. If you use an HTML inspector, often you are actually seeing the DOM, not the raw HTML. Browsers parse HTML into the DOM, and the after-parsing DOM representation already has some niceties applied. In this case the Browser sees there aren't quotes around the attribute value, adds them:
style=""border:0px""
But in the DOM inspector HTML character codes display properly so you actually see:
style=""border:0px""
In Chrome, if you right-click and select Edit HTML, it switch back so you can see those nasty HTML character codes, making it clear you have real outer quotes, and HTML encoded inner quotes.
So the problem with trying to do the quoting yourself is Razor escapes these.
Use Html.Raw to prevent quote escaping:
<td @Html.Raw( someBoolean ? "rel='tooltip' data-container='.drillDown a'" : "" )>
Renders as:
<td rel='tooltip' title='Drilldown' data-container='.drillDown a'>
The above is perfectly safe because I'm not outputting any HTML from a variable. The only variable involved is the ternary condition. However, beware that this last technique might expose you to certain security problems if building strings from user supplied data. E.g. if you built an attribute from data fields that originated from user supplied data, use of Html.Raw means that string could contain a premature ending of the attribute and tag, then begin a script tag that does something on behalf of the currently logged in user(possibly different than the logged in user). Maybe you have a page with a list of all users pictures and you are setting a tooltip to be the username of each person, and one users named himself '/><script>$.post('changepassword.php?password=123')</script>
and now any other user who views this page has their password instantly changed to a password that the malicious user knows.

Postgres documentation describes the differences between UUID
s. A couple of them:
V3:
uuid_generate_v3(namespace uuid, name text)
- This function generates a version 3 UUID in the given namespace using the specified input name.
V4:
uuid_generate_v4
- This function generates a version 4 UUID, which is derived entirely from random numbers.
Try rename
command:
rename 's/_h.png/_half.png/' *.png
Update:
example usage:
create some content
$ mkdir /tmp/foo
$ cd /tmp/foo
$ touch one_h.png two_h.png three_h.png
$ ls
one_h.png three_h.png two_h.png
test solution:
$ rename 's/_h.png/_half.png/' *.png
$ ls
one_half.png three_half.png two_half.png
In C/C++, pointers and arrays are (almost) equivalent.
int *a; a[0];
will return *a
, and a[1];
will return *(a + 1)
But array can't change the pointer it points to while pointer can.
new int[n]
will allocate some spaces for the "array"
A small variation on Husky's idea that I use. Make a file called 'globals' (or whatever you like) and then define multiple classes in it, as such:
#globals.py
class dbinfo : # for database globals
username = 'abcd'
password = 'xyz'
class runtime :
debug = False
output = 'stdio'
Then, if you have two code files c1.py and c2.py, both can have at the top
import globals as gl
Now all code can access and set values, as such:
gl.runtime.debug = False
print(gl.dbinfo.username)
People forget classes exist, even if no object is ever instantiated that is a member of that class. And variables in a class that aren't preceded by 'self.' are shared across all instances of the class, even if there are none. Once 'debug' is changed by any code, all other code sees the change.
By importing it as gl, you can have multiple such files and variables that lets you access and set values across code files, functions, etc., but with no danger of namespace collision.
This lacks some of the clever error checking of other approaches, but is simple and easy to follow.
Filter using wildcards:
Get-ChildItem -Filter CopyForBuild* -Include *.bat,*.cmd -Exclude *.old.cmd,*.old.bat -Recurse
Filtering using a regular expression:
Get-ChildItem -Path "V:\Myfolder" -Recurse
| Where-Object { $_.Name -match '\ACopyForBuild\.[(bat)|(cmd)]\Z' }
GROUP BY meetingID
HAVING COUNT(caseID) < 4 AND COUNT(caseID) > 2
I had this problem too, and in my case I found that the color of the font was the same color of the background, so it looked like nothing happened.
If you accidentally write beyond the block allocated with alloca
(due to a buffer overflow for example), then you will overwrite the return address of your function, because that one is located "above" on the stack, i.e. after your allocated block.
The consequence of this is two-fold:
The program will crash spectacularly and it will be impossible to tell why or where it crashed (stack will most likely unwind to a random address due to the overwritten frame pointer).
It makes buffer overflow many times more dangerous, since a malicious user can craft a special payload which would be put on the stack and can therefore end up executed.
In contrast, if you write beyond a block on the heap you "just" get heap corruption. The program will probably terminate unexpectedly but will unwind the stack properly, thereby reducing the chance of malicious code execution.
Use git gui
, there you can see a list of what changed in your actual commit. You can also use gitk
wich provides an easy interface for reflogs. Just compare between remotes/...
and master
to see, what will be pushed. It provides an interface similar to your screenshot.
Both programs are included in git.
That entire block is misplaced.
class Example(object):
def main(self):
print "Hello World!"
if __name__ == '__main__':
Example().main()
But you really shouldn't be using a class just to run your main code.
In the example above. For me, this if($response.success==false)
thing does not work. Here is correct PHP code:
$url = 'https://www.google.com/recaptcha/api/siteverify';
$privatekey = "--your_key--";
$response = file_get_contents($url."?secret=".$privatekey."&response=".$_POST['g-recaptcha-response']."&remoteip=".$_SERVER['REMOTE_ADDR']);
$data = json_decode($response);
if (isset($data->success) AND $data->success==true) {
// everything is ok!
} else {
// spam
}
You could try lattice:
require(lattice)
x <- 1:100000
y <- 1:100000
xyplot(y~x, scales=list(x = list(log = 10)), type="l")
We have seen this same behavior in the past. It turned out that, for some crazy reason, if a NullPointerException occurred at the same place in the code multiple times, after a while using Log.error(String, Throwable)
would stop including full stack traces.
Try looking further back in your log. You may find the culprit.
EDIT: this bug sounds relevant, but it was fixed so long ago it's probably not the cause.
extends
has no facility for this. Either put the entire template path in a context variable and use that, or copy the exist template tag and modify it appropriately.
Git has three modes of how it treats line endings:
$ git config core.autocrlf
# that command will print "true" or "false" or "input"
You can set the mode to use by adding an additional parameter of true
or false
to the above command line.
If core.autocrlf
is set to true, that means that any time you add a file to the git repo that git thinks is a text file, it will turn all CRLF line endings to just LF before it stores it in the commit. Whenever you git checkout
something, all text files automatically will have their LF line endings converted to CRLF endings. This allows development of a project across platforms that use different line-ending styles without commits being very noisy because each editor changes the line ending style as the line ending style is always consistently LF.
The side-effect of this convenient conversion, and this is what the warning you're seeing is about, is that if a text file you authored originally had LF endings instead of CRLF, it will be stored with LF as usual, but when checked out later it will have CRLF endings. For normal text files this is usually just fine. The warning is a "for your information" in this case, but in case git incorrectly assesses a binary file to be a text file, it is an important warning because git would then be corrupting your binary file.
If core.autocrlf
is set to false, no line-ending conversion is ever performed, so text files are checked in as-is. This usually works ok, as long as all your developers are either on Linux or all on Windows. But in my experience I still tend to get text files with mixed line endings that end up causing problems.
My personal preference is to leave the setting turned ON, as a Windows developer.
See http://kernel.org/pub/software/scm/git/docs/git-config.html for updated info that includes the "input" value.
My 2 cents, write
*{ margin:0; padding:0; }
in your target page main css, add a content div with the height size of all your elements, don't touch the .js, listo, saludos
Yeap, you just need to make .
match newline :
$string =~ /(START)(.+?)(END)/s;
A simple way of doing this that I found as a comment by @awardak in Brandon Rude's answer:
new Thread( new Runnable() { @Override public void run() {
// Run whatever background code you want here.
} } ).start();
I'm not sure if, or how , this is better than using AsyncTask.execute
but it seems to work for us. Any comments as to the difference would be appreciated.
Thanks, @awardak!

I was having all my website set up first in XAMMP, then I had to transfer it to LAMP, in a SUSE installation of LAMP, where I got this error.

(My first and lame guess would be that's because of old version of mysql, as built-in installations come with older versions.

Using innerHTML is SO NOT RECOMMENDED. Instead, you should create a textNode. This way, you are "binding" your text and you are not, at least in this case, vulnerable to an XSS attack.
document.getElementById("myspan").innerHTML = "sometext"; //INSECURE!!
The right way:
span = document.getElementById("myspan");
txt = document.createTextNode("your cool text");
span.appendChild(txt);

Edited nov 4th 2017:
Modified third line of code according to @mumush suggestion: "use appendChild(); instead".
Btw, according to @Jimbo Jonny I think everything should be treated as user input by applying Security by layers principle. That way you won't encounter any surprises.
double doublVal = 123.45678;
There are two ways.
for display in string:
String.Format("{0:0.00}", doublVal );
for geting again Double
doublVal = Convert.ToDouble(String.Format("{0:0.00}", doublVal ));
For anyone having issues with Visual Studio 2019:
I had to first open menu Test ? Windows ? Test Explorer, and run the tests from there, before the option to Run / Debug tests would show up on the right click menu.
Use some regex like [0-9]
or \d
:
$words = preg_replace('/\d+/', '', $words );
You might want to read the preg_replace() documentation as this is directly shown there.
If your background is solid (or you can reproduce it using CSS), you can use linear gradient that way:
div {_x000D_
background-image: linear-gradient(to top, rgba(0, 0, 0, 0) 0%, rgba(0, 0, 0, 0.3) 5px, #fff 5px, #fff 100%)_x000D_
}
_x000D_
<div>_x000D_
<p>Foobar</p>_x000D_
<p>test</p>_x000D_
</div>
_x000D_
This will generate a 5px gradient at the bottom of the element, from black at 30% opacity to completely transparent. The rest of the element has white background. Of course, changing the last 2 color stops of the linear gradient, you could make the background completely transparent.
To solve this simply add android:windowSoftInputMode="stateVisible|adjustPan
to that activity in android manifest file. for example
<activity
android:name="com.comapny.applicationname.activityname"
android:screenOrientation="portrait"
android:windowSoftInputMode="stateVisible|adjustPan"/>
You get a recursion error because your attempt to access the self.__dict__
attribute inside __getattribute__
invokes your __getattribute__
again. If you use object
's __getattribute__
instead, it works:
class D(object):
def __init__(self):
self.test=20
self.test2=21
def __getattribute__(self,name):
if name=='test':
return 0.
else:
return object.__getattribute__(self, name)
This works because object
(in this example) is the base class. By calling the base version of __getattribute__
you avoid the recursive hell you were in before.
Ipython output with code in foo.py:
In [1]: from foo import *
In [2]: d = D()
In [3]: d.test
Out[3]: 0.0
In [4]: d.test2
Out[4]: 21
Update:
There's something in the section titled More attribute access for new-style classes in the current documentation, where they recommend doing exactly this to avoid the infinite recursion.
It looks like you are trying to parse each line. You've been shown by another answer how to use getline
in a loop to seperate each line. The other tool you are going to want is istringstream
, to seperate each token.
std::string line;
while(std::getline(file, line))
{
std::istringstream iss(line);
std::string token;
while (iss >> token)
{
// do something with token
}
}
I've contemplated this a few times in the past so thought I'd jot down the different ideas I've had / used. Something might be of use, but none are "perfect" Symfony2 solutions.
Constructor In the Entity you can do $this->setBar('default value'); but this is called every time you load the entity (db or not) and is a bit messy. It does however work for every field type as you can create dates or whatever else you need.
If statements within get's I wouldn't, but you could.
return ( ! $this->hasFoo() ) ? 'default' : $this->foo;
Factory / instance. Call a static function / secondary class which provides you a default Entity pre-populated with data. E.g.
function getFactory() {
$obj = new static();
$obj->setBar('foo');
$obj->setFoo('bar');
return $obj;
}
Not really ideal given you'll have to maintain this function if you add extra fields, but it does mean you're separating the data setters / default and that which is generated from the db. Similarly you can have multiple getFactories should you want different defaulted data.
Extended / Reflection entities Create a extending Entity (e.g. FooCreate extends Foo) which gives you the defaulted data at create time (through the constructor). Similar to the Factory / instance idea just a different approach - I prefer static methods personally.
Set Data before build form In the constructors / service, you know if you have a new entity or if it was populated from the db. It's plausible therefore to call set data on the different fields when you grab a new entity. E.g.
if( ! $entity->isFromDB() ) {
$entity->setBar('default');
$entity->setDate( date('Y-m-d');
...
}
$form = $this->createForm(...)
Form Events When you create the form you set default data when creating the fields. You override this use PreSetData event listener. The problem with this is that you're duplicating the form workload / duplicating code and making it harder to maintain / understand.
Extended forms Similar to Form events, but you call the different type depending on if it's a db / new entity. By this I mean you have FooType which defines your edit form, BarType extends FooType this and sets all the data to the fields. In your controller you then simply choose which form type to instigate. This sucks if you have a custom theme though and like events, creates too much maintenance for my liking.
Twig You can create your own theme and default the data using the value option too when you do it on a per-field basis. There is nothing stopping you wrapping this into a form theme either should you wish to keep your templates clean and the form reusable. e.g.
form_widget(form.foo, {attr: { value : default } });
JS It'd be trivial to populate the form with a JS function if the fields are empty. You could do something with placeholders for example. This is a bad, bad idea though.
Forms as a service For one of the big form based projects I did, I created a service which generated all the forms, did all the processing etc. This was because the forms were to be used across multiple controllers in multiple environments and whilst the forms were generated / handled in the same way, they were displayed / interacted with differently (e.g. error handling, redirections etc). The beauty of this approach was that you can default data, do everything you need, handle errors generically etc and it's all encapsulated in one place.
Conclusion As I see it, you'll run into the same issue time and time again - where is the defaulted data to live?
To that end, I've approached the problem differently each time. For example, a signup form "newsletter" option is easily (and logically) set in the constructor just before creating the form. When I was building forms collections which were linked together (e.g. which radio buttons in different form types linked together) then I've used Event Listeners. When I've built a more complicated entity (e.g. one which required children or lots of defaulted data) I've used a function (e.g. 'getFactory') to create it element as I need it.
I don't think there is one "right" approach as every time I've had this requirement it's been slightly different.
Good luck! I hope I've given you some food for thought at any rate and didn't ramble too much ;)
In regards to veggerby's solution, if you are trying to implement it on a VB app, be careful trying to run the supplied code through a translator. The following will work:
Imports System.Web
Imports System.Web.Services
Imports System.Web.SessionState
Public Class SessionHeartbeatHttpHandler
Implements IHttpHandler
Implements IRequiresSessionState
ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
Get
Return False
End Get
End Property
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
context.Session("Heartbeat") = DateTime.Now
End Sub
End Class
Also, instead of calling like heartbeat() function like:
setTimeout("heartbeat()", 300000);
Instead, call it like:
setInterval(function () { heartbeat(); }, 300000);
Number one, setTimeout only fires once whereas setInterval will fire repeatedly. Number two, calling heartbeat() like a string didn't work for me, whereas calling it like an actual function did.
And I can absolutely 100% confirm that this solution will overcome GoDaddy's ridiculous decision to force a 5 minute apppool session in Plesk!
This is not politically correct but works
->leftJoin("players as p","n.item_id", "=", DB::raw("p.id_player and n.type='player'"))
Both of these should work:
df.isnull().sum()
df.isna().sum()
DataFrame methods isna()
or isnull()
are completely identical.
Note: Empty strings ''
is considered as False (not considered NA)
This worked for me: (notice that java 8 is required)
String requestData = request.getReader().lines().collect(Collectors.joining());
UserJsonParser u = gson.fromJson(requestData, UserJsonParser.class);
UserJsonParse is a class that shows gson how to parse the json formant.
class is like that:
public class UserJsonParser {
private String username;
private String name;
private String lastname;
private String mail;
private String pass1;
//then put setters and getters
}
the json string that is parsed is like that:
$jsonData: { "username": "testuser", "pass1": "clave1234" }
The rest of values (mail, lastname, name) are set to null
Sign-off is a line at the end of the commit message which certifies who is the author of the commit. Its main purpose is to improve tracking of who did what, especially with patches.
Example commit:
Add tests for the payment processor.
Signed-off-by: Humpty Dumpty <[email protected]>
It should contain the user real name if used for an open-source project.
If branch maintainer need to slightly modify patches in order to merge them, he could ask the submitter to rediff, but it would be counter-productive. He can adjust the code and put his sign-off at the end so the original author still gets credit for the patch.

I'm aware he's not asking for the inline version. But since this question has almost 100k visits and I fell here looking for that, I'll leave it here for the next fellow coder:
Make sure ESLint is not run with the --no-inline-config
flag (if this doesn't sound familiar, you're likely good to go). Then, write this in your code file (for clarity and convention, it's written on top of the file but it'll work anywhere):
/* eslint-env browser */
This tells ESLint that your working environment is a browser, so now it knows what things are available in a browser and adapts accordingly.
There are plenty of environments, and you can declare more than one at the same time, for example, in-line:
/* eslint-env browser, node */
If you are almost always using particular environments, it's best to set it in your ESLint's config file and forget about it.
From their docs:
An environment defines global variables that are predefined. The available environments are:
browser
- browser global variables.node
- Node.js global variables and Node.js scoping.commonjs
- CommonJS global variables and CommonJS scoping (use this for browser-only code that uses Browserify/WebPack).shared-node-browser
- Globals common to both Node and Browser.[...]
Besides environments, you can make it ignore anything you want. If it warns you about using console.log()
but you don't want to be warned about it, just inline:
/* eslint-disable no-console */
You can see the list of all rules, including recommended rules to have for best coding practices.
Either:
DateTime dt = new DateTime();
or
DateTime dt = default(DateTime);
Hiding navigation bar only on first page can be achieved through storyboard as well. On storyboard, goto Navigation Controller Scene->Navigation Bar. And select 'Hidden' property from the Attributes inspector. This will hide navigation bar starting from first viewcontroller until its made visible for the required viewcontroller.
Navigation bar can be set back to visible in ViewController's ViewWillAppear callback.
-(void)viewWillAppear:(BOOL)animated {
[self.navigationController setNavigationBarHidden:YES animated:animated];
[super viewWillAppear:animated];
}
SET @customerID=0;
SELECT @customerID:=@customerID+1 AS customerID
FROM CUSTOMER ;
you can obtain the dataset from SQL like this and populate it into a java data structure (like a List) and then make the necessary sorting over there. (maybe with the help of a comparable interface)
Where is it pushed on?
esp - 4
. More precisely:
esp
gets subtracted by 4esp
pop
reverses this.
The System V ABI tells Linux to make rsp
point to a sensible stack location when the program starts running: What is default register state when program launches (asm, linux)? which is what you should usually use.
How can you push a register?
Minimal GNU GAS example:
.data
/* .long takes 4 bytes each. */
val1:
/* Store bytes 0x 01 00 00 00 here. */
.long 1
val2:
/* 0x 02 00 00 00 */
.long 2
.text
/* Make esp point to the address of val2.
* Unusual, but totally possible. */
mov $val2, %esp
/* eax = 3 */
mov $3, %ea
push %eax
/*
Outcome:
- esp == val1
- val1 == 3
esp was changed to point to val1,
and then val1 was modified.
*/
pop %ebx
/*
Outcome:
- esp == &val2
- ebx == 3
Inverses push: ebx gets the value of val1 (first)
and then esp is increased back to point to val2.
*/
The above on GitHub with runnable assertions.
Why is this needed?
It is true that those instructions could be easily implemented via mov
, add
and sub
.
They reason they exist, is that those combinations of instructions are so frequent, that Intel decided to provide them for us.
The reason why those combinations are so frequent, is that they make it easy to save and restore the values of registers to memory temporarily so they don't get overwritten.
To understand the problem, try compiling some C code by hand.
A major difficulty, is to decide where each variable will be stored.
Ideally, all variables would fit into registers, which is the fastest memory to access (currently about 100x faster than RAM).
But of course, we can easily have more variables than registers, specially for the arguments of nested functions, so the only solution is to write to memory.
We could write to any memory address, but since the local variables and arguments of function calls and returns fit into a nice stack pattern, which prevents memory fragmentation, that is the best way to deal with it. Compare that with the insanity of writing a heap allocator.
Then we let compilers optimize the register allocation for us, since that is NP complete, and one of the hardest parts of writing a compiler. This problem is called register allocation, and it is isomorphic to graph coloring.
When the compiler's allocator is forced to store things in memory instead of just registers, that is known as a spill.
Does this boil down to a single processor instruction or is it more complex?
All we know for sure is that Intel documents a push
and a pop
instruction, so they are one instruction in that sense.
Internally, it could be expanded to multiple microcodes, one to modify esp
and one to do the memory IO, and take multiple cycles.
But it is also possible that a single push
is faster than an equivalent combination of other instructions, since it is more specific.
This is mostly un(der)documented:
push
and pop
take one single micro operation. This works for me

I would say in some cases it's ok to do nothing. Probably not something you should be doing by default, but in case there should be no way for the interrupt to happen, I'm not sure what else to do (probably logging error, but that does not affect program flow).
One case would be in case you have a task (blocking) queue. In case you have a daemon Thread handling these tasks and you do not interrupt the Thread by yourself (to my knowledge the jvm does not interrupt daemon threads on jvm shutdown), I see no way for the interrupt to happen, and therefore it could be just ignored. (I do know that a daemon thread may be killed by the jvm at any time and therefore are unsuitable in some cases).
EDIT: Another case might be guarded blocks, at least based on Oracle's tutorial at: http://docs.oracle.com/javase/tutorial/essential/concurrency/guardmeth.html

The short version is that it creates patch files of the given file or directory ($object

git format-patch --thread -o "$temp" --root -- "$object"
which then get applied to a new repository:
cd new_repo

If you're using getValue()
you're doing something imperative in declarative paradigm. It's there as an escape hatch, but 99.9% of the time you should NOT use getValue()
. There are a few interesting things that getValue()
will do: It will throw an error if the subject has been unsubscribed, it will prevent you from getting a value if the subject is dead because it's errored, etc. But, again, it's there as an escape hatch for rare circumstances.
There are several ways of getting the latest value from a Subject or Observable in a "Rx-y" way:
BehaviorSubject
: But actually subscribing to it. When you first subscribe to BehaviorSubject
it will synchronously send the previous value it received or was initialized with.ReplaySubject(N)
: This will cache N
values and replay them to new subscribers.A.withLatestFrom(B)
: Use this operator to get the most recent value from observable B
when observable A
emits. Will give you both values in an array [a, b]
.A.combineLatest(B)
: Use this operator to get the most recent values from A
and B
every time either A
or B
emits. Will give you both values in an array.shareReplay()
: Makes an Observable multicast through a ReplaySubject
, but allows you to retry the observable on error. (Basically it gives you that promise-y caching behavior).publishReplay()
, publishBehavior(initialValue)
, multicast(subject: BehaviorSubject | ReplaySubject)
, etc: Other operators that leverage BehaviorSubject
and ReplaySubject
. Different flavors of the same thing, they basically multicast the source observable by funneling all notifications through a subject. You need to call connect()
to subscribe to the source with the subject.Number(new Date(2010, 6, 26))
Works the same way as things above. If you need seconds don't forget to / 1000

UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!)
In Swift 3:
UIApplication.shared.open(URL(string:UIApplicationOpenSettingsURLString)!)
In Swift 2:
UIApplication.sharedApplication().openURL(NSURL(string:UIApplicationOpenSettingsURLString)!)
In Objective-C
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
Prior to iOS 8:
You can not. As you said this has been covered many times and that pop up asking you to turn on location services is supplied by Apple and not by the App itself. That is why it is able to the open the settings application.
Here are a few related questions & articles:
is it possible to open Settings App using openURL?

Recommended solution is to install and trust a self-signed certificate (root). Assuming you created your own CA and the hierarchy of the certificated is correct you don't need to change the server trust evaluation. This is recommended because it doesn't require any changes in the code.
If it is not possible then you need to change server trust evaluation.

If you want to add a query parameter after you have created the request, try casting the HttpRequest
to a HttpBaseRequest
. Then you can change the URI of the casted request:
HttpGet someHttpGet = new HttpGet("http://google.de");
URI uri = new URIBuilder(someHttpGet.getURI()).addParameter("q",
"That was easy!").build();
((HttpRequestBase) someHttpGet).setURI(uri);
Modulus operator, it is used for remainder division on integers, typically, but in Python can be used for floating point numbers.
http://docs.python.org/reference/expressions.html
The % (modulo) operator yields the remainder from the division of the first argument by the second. The numeric arguments are first converted to a common type. A zero right argument raises the ZeroDivisionError exception. The arguments may be floating point numbers, e.g., 3.14%0.7 equals 0.34 (since 3.14 equals 4*0.7 + 0.34.) The modulo operator always yields a result with the same sign as its second operand (or zero); the absolute value of the result is strictly smaller than the absolute value of the second operand [2].
Using
generates a try / finally around the object being allocated and calls Dispose()
for you.
It saves you the hassle of manually creating the try / finally block and calling Dispose()
How about something like
=LEFT(A1,SEARCH(" ",A1)-1)
or
=LEFT(A1,SEARCH("<b>",A1)-1)
Have a look at MS Excel: Search Function and Excel 2007 LEFT Function
When I had the same problem I fixed it by deleting the existing key.snk
in that project and adding a new key.
Realizing the revision of the code I found the cause of why the reading method did not work for me. The problem was that one of the dependencies that my project used jersey 1.x. Update the version, adjust the client and it works.
I use the following maven dependency:
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.28</version>

Set the PATH variable, like you're doing. If you're running the program from the IDE, you can modify environment variables by adjusting the Debugging options in the project properties.
If the DLLs are named such that you don't need different paths for the different configuration types, you can add the path to the system PATH variable or to Visual Studio's global one in Tools | Options.
This can be achieved by a T-SQL statement, if you are aware that FROM
clause can specify database for table name.
insert into database1..MyTable
select from database2..MyTable
Here is how Microsoft explains the syntax: https://docs.microsoft.com/en-us/sql/t-sql/queries/from-transact-sql?view=sql-server-ver15
If the table or view exists in another database on the same instance of SQL Server, use a fully qualified name in the form
database.schema.object_name
.
schema_name
can be omitted, like above, which means the default schema of the current user. By default, it's dbo
.
Add any filtering to columns/rows if you want to. Be sure to create any new table before moving data.
function getStyle(className) {
document.styleSheets.item("menu").cssRules.item(className).cssText;
}
getStyle('.test')
Note : "menu" is an element ID which you have applied CSS. "className" a css class name which we need to get its text.
My case was different the child view already had a parent view i am adding the child view inside parent view to different parent. example code below
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/lineGap"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@color/black1"
android:layout_gravity="center"
android:gravity="center"
/>
</LinearLayout>
And i was inflating this view and adding to another LinearLayout, then i removed the LinaarLayout from the above layout and its started working
below code fixed the issue:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="@color/black1" />
This issue can be solved by CSS.
.image{
max-width:*px;
}
on windows 10, Notepad 7.8.5, i found this solution to convert from CRLF to LF.
Edit > Format end of line
and choose either Windows(CR+LF)
or Unix(LF)
<script type="text/javascript">
document.getElementById('button1').onChange = function () {
document.getElementById('hidden_field_id').value = document.getElementById('span_id').innerHTML;
}
</script>
If you don't want to deal with the pain of the conversion every time simply create an extension method.
public static class Extensions
{
public static SolidColorBrush ToBrush(this string HexColorString)
{
return (SolidColorBrush)(new BrushConverter().ConvertFrom(HexColorString));
}
}
Then use like this: BackColor = "#FFADD8E6".ToBrush()
Alternately if you could provide a method to do the same thing.
public SolidColorBrush BrushFromHex(string hexColorString)
{
return (SolidColorBrush)(new BrushConverter().ConvertFrom(hexColorString));
}
BackColor = BrushFromHex("#FFADD8E6");
I really liked the answer of RichieHindle, however I liked the question as an exercise. Here's a brute force implementation using strings:)
import random
first = random.randint(1,9)
first = str(first)
n = 5
nrs = [str(random.randrange(10)) for i in range(n-1)]
for i in range(len(nrs)) :
first += str(nrs[i])
print str(first)
Swift 3
func getTime() -> (hour: Int, minute: Int,second: Int) {
let hour = 1
let minute = 20
let second = 55
return (hour, minute, second)
}
To use :
let(hour, min,sec) = self.getTime()
print(hour,min,sec)
The system I was working on is Windows Server 2008 Standard with IIS 7 (I guess that my experience will apply for all Windows systems of the same age).
Running
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir
SEEMED to work, as
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -lv
showed the .Net framework v4 registered with IIS.
But, running the same for .Net v2, namely
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -ir
did NOT result in
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -lv
showing the framework registered.
(And, for me, the installer for Kofax Capture Network Server was still missing ASP.NET.)
The solution was:
After that, aspnet_regiis.exe -lv (either version) shows the framework registered. (And the Kofax installer was also happy and worked.)
Related information, especially if you are using NTVS for working with the Visual Studio IDE. The NTVS adds both NodeJS and Express tools, scaffolding, project templates to Visual Studio 2012, 2013.
Also, the verbiage that calls ExpressJS or Connect as a "WebServer" is incorrect. You can create a basic WebServer with or without them. A basic NodeJS program can also use the http module to handle http requests, Thus becoming a rudimentary web server.

git-aliases, awk and shell-functions to the rescue!
git prevision <N> <filename>
where <N>
is the number of revisions of the file to rollback for file <filename>
.
For example, to checkout the immediate previous revision of a single file x/y/z.c
, run
git prevision -1 x/y/z.c
Add the following to your gitconfig
[alias]
prevision = "!f() { git checkout `git log --oneline $2 | awk -v commit="$1" 'FNR == -commit+1 {print $1}'` $2;} ;f"
The command basically
- performs a
git log
on the specified file and- picks the appropriate commit-id in the history of the file and
- executes a
git checkout
to the commit-id for the specified file.
Essentially, all that one would manually do in this situation,
wrapped-up in one beautiful, efficient git-alias - git-prevision
Redacted version of my article FTP Connection Modes (Active vs. Passive):
FTP connection mode (active or passive), determines how a data connection is established. In both cases, a client creates a TCP control connection to an FTP server command port 21. This is a standard outgoing connection, as with any other file transfer protocol (SFTP, SCP, WebDAV) or any other TCP client application (e.g. web browser). So, usually there are no problems when opening the control connection.
Where FTP protocol is more complicated comparing to the other file transfer protocols are file transfers. While the other protocols use the same connection for both session control and file (data) transfers, the FTP protocol uses a separate connection for the file transfers and directory listings.
In the active mode, the client starts listening on a random port for incoming data connections from the server (the client sends the FTP command PORT
to inform the server on which port it is listening). Nowadays, it is typical that the client is behind a firewall (e.g. built-in Windows firewall) or NAT router (e.g. ADSL modem), unable to accept incoming TCP connections.
For this reason the passive mode was introduced and is mostly used nowadays. Using the passive mode is preferable because most of the complex configuration is done only once on the server side, by experienced administrator, rather than individually on a client side, by (possibly) inexperienced users.
In the passive mode, the client uses the control connection to send a PASV
command to the server and then receives a server IP address and server port number from the server, which the client then uses to open a data connection to the server IP address and server port number received.
With the passive mode, most of the configuration burden is on the server side. The server administrator should setup the server as described below.
The firewall and NAT on the FTP server side have to be configured not only to allow/route the incoming connections on FTP port 21 but also a range of ports for the incoming data connections. Typically, the FTP server software has a configuration option to setup a range of the ports, the server will use. And the same range has to be opened/routed on the firewall/NAT.
When the FTP server is behind a NAT, it needs to know it's external IP address, so it can provide it to the client in a response to PASV
command.
With the active mode, most of the configuration burden is on the client side.
The firewall (e.g. Windows firewall) and NAT (e.g. ADSL modem routing rules) on the client side have to be configured to allow/route a range of ports for the incoming data connections. To open the ports in Windows, go to Control Panel > System and Security > Windows Firewall > Advanced Settings > Inbound Rules > New Rule. For routing the ports on the NAT (if any), refer to its documentation.
When there's NAT in your network, the FTP client needs to know its external IP address that the WinSCP needs to provide to the FTP server using PORT
command. So that the server can correctly connect back to the client to open the data connection. Some FTP clients are capable of autodetecting the external IP address, some have to be manually configured.
Some firewalls/NATs try to automatically open/close data ports by inspecting FTP control connection and/or translate the data connection IP addresses in control connection traffic.
With such a firewall/NAT, the above configuration is not necessary for a plain unencrypted FTP. But this cannot work with FTPS, as the control connection traffic is encrypted and the firewall/NAT cannot inspect nor modify it.
Updating @Dario's code approach for Xcode 8.2.2, Swift 3.x. Noting that in storyboard, set the Background color to "clear" to avoid a black background in the square UIView:
import UIKit
@IBDesignable
class Dot:UIView
{
@IBInspectable var mainColor: UIColor = UIColor.clear
{
didSet { print("mainColor was set here") }
}
@IBInspectable var ringColor: UIColor = UIColor.clear
{
didSet { print("bColor was set here") }
}
@IBInspectable var ringThickness: CGFloat = 4
{
didSet { print("ringThickness was set here") }
}
@IBInspectable var isSelected: Bool = true
override func draw(_ rect: CGRect)
{
let dotPath = UIBezierPath(ovalIn: rect)
let shapeLayer = CAShapeLayer()
shapeLayer.path = dotPath.cgPath
shapeLayer.fillColor = mainColor.cgColor
layer.addSublayer(shapeLayer)
if (isSelected) { drawRingFittingInsideView(rect: rect) }
}
internal func drawRingFittingInsideView(rect: CGRect)->()
{
let hw:CGFloat = ringThickness/2
let circlePath = UIBezierPath(ovalIn: rect.insetBy(dx: hw,dy: hw) )
let shapeLayer = CAShapeLayer()
shapeLayer.path = circlePath.cgPath
shapeLayer.fillColor = UIColor.clear.cgColor
shapeLayer.strokeColor = ringColor.cgColor
shapeLayer.lineWidth = ringThickness
layer.addSublayer(shapeLayer)
}
}
And if you want to control the start and end angles:
import UIKit
@IBDesignable
class Dot:UIView
{
@IBInspectable var mainColor: UIColor = UIColor.clear
{
didSet { print("mainColor was set here") }
}
@IBInspectable var ringColor: UIColor = UIColor.clear
{
didSet { print("bColor was set here") }
}
@IBInspectable var ringThickness: CGFloat = 4
{
didSet { print("ringThickness was set here") }
}
@IBInspectable var isSelected: Bool = true
override func draw(_ rect: CGRect)
{
let dotPath = UIBezierPath(ovalIn: rect)
let shapeLayer = CAShapeLayer()
shapeLayer.path = dotPath.cgPath
shapeLayer.fillColor = mainColor.cgColor
layer.addSublayer(shapeLayer)
if (isSelected) { drawRingFittingInsideView(rect: rect) }
}
internal func drawRingFittingInsideView(rect: CGRect)->()
{
let halfSize:CGFloat = min( bounds.size.width/2, bounds.size.height/2)
let desiredLineWidth:CGFloat = ringThickness // your desired value
let circlePath = UIBezierPath(
arcCenter: CGPoint(x: halfSize, y: halfSize),
radius: CGFloat( halfSize - (desiredLineWidth/2) ),
startAngle: CGFloat(0),
endAngle:CGFloat(Double.pi),
clockwise: true)
let shapeLayer = CAShapeLayer()
shapeLayer.path = circlePath.cgPath
shapeLayer.fillColor = UIColor.clear.cgColor
shapeLayer.strokeColor = ringColor.cgColor
shapeLayer.lineWidth = ringThickness
layer.addSublayer(shapeLayer)
}
}
In the spectrum of kernel designs the two extreme points are monolithic kernels and microkernels.
The (classical) Linux kernel for instance is a monolithic kernel (and so is every commercial OS to date as well - though they might claim otherwise);
In that its code is a
single C file giving rise to a single process that implements all of the above
services.
To exemplify the encapsulation of the Linux kernel we remark that
the Linux kernel does not even have access to any of the standard C libraries.
Indeed the Linux kernel cannot use rudimentary C library functions such as
printf. Instead it implements its own printing function (called prints).
This seclusion of the Linux kernel and self-containment provide Linux kernel
with its main advantage: the kernel resides in a single address space1
enabling
all features to communicate in the fastest way possible without resorting to
any type of message passing.
In particular, a monolithic kernel implements all of the device drivers
of the system.
This however is the main drawback of a monolithic kernel:
introduction of any new unsupported hardware requires a rewrite of the
kernel (in the relevant parts), recompilation of it, and re-installing the entire
OS.
More importantly, if any device driver crashes the entire kernel suffers
as a result.
This un-modular approach to hardware additions and hardware crashes
is the main argument for supporting the other extreme design approach
for kernels. A microkernel is in a sense a minimalistic kernel that houses
only the very basic of OS services (like process management and file system
management). In a microkernel the device drivers lie outside of the kernel
allowing for addition and removal of device drivers while the OS is running
and require no alternations of the kernel.
My solution to this was to write the script block dynamically with [scriptblock]:Create
:
# Or build a complex local script with MARKERS here, and do substitutions
# I was sending install scripts to the remote along with MSI packages
# ...for things like Backup and AV protection etc.
$p1 = "good stuff"; $p2 = "better stuff"; $p3 = "best stuff"; $etc = "!"
$script = [scriptblock]::Create("MyScriptOnRemoteServer.ps1 $p1 $p2 $etc")
#strings get interpolated/expanded while a direct scriptblock does not
# the $parms are now expanded in the script block itself
# ...so just call it:
$result = invoke-command $computer -script $script
Passing arguments was very frustrating, trying various methods, e.g.,
-arguments
, $using:p1
, etc. and this just worked as desired with no problems.
Since I control the contents and variable expansion of the string which creates the [scriptblock]
(or script file) this way, there is no real issue with the "invoke-command" incantation.
(It shouldn't be that hard. :) )
You can use Material UI's Input and InputLabel components. Here's an example if you were using them to input spreadsheet files.
import { Input, InputLabel } from "@material-ui/core";
const styles = {
hidden: {
display: "none",
},
importLabel: {
color: "black",
},
};
<InputLabel htmlFor="import-button" style={styles.importLabel}>
<Input
id="import-button"
inputProps={{
accept:
".csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel",
}}
onChange={onInputChange}
style={styles.hidden}
type="file"
/>
Import Spreadsheet
</InputLabel>
FYI, this is probably faster,
SELECT count(1) FROM (SELECT distinct productId WHERE keyword = '$keyword') temp
than this,
SELECT COUNT(DISTINCT productId) WHERE keyword='$keyword'
I used this and it is very simple to implement
import tinys3
conn = tinys3.Connection('S3_ACCESS_KEY','S3_SECRET_KEY',tls=True)
f = open('some_file.zip','rb')
conn.upload('some_file.zip',f,'my_bucket')
ps -eLf
on the shell shall give you a list of all the threads and processes currently running on the system.
Or, you can run top
command then hit 'H' to toggle thread listings.
I think you're confused about what binary is. Binary and decimal are just different representations of a number - e.g. 101 base 2 and 5 base 10 are the same number. The operations add, subtract, and compare operate on numbers - 101 base 2 == 5 base 10 and addition is the same logical operation no matter what base you're working in.
Okay, I know I'm late to the party. But let me share with you what worked for me. The tabindex and z-index solutions did not work for me.
Setting the parent of the select element worked as per the common problems listed on select2 site.
AFAIK, an Iframe cannot be used that way. You need to point its src attribute to another page.
Here's how to get its body content using plane old javascript. This works with both IE and Firefox.
function getFrameContents(){
var iFrame = document.getElementById('id_description_iframe');
var iFrameBody;
if ( iFrame.contentDocument )
{ // FF
iFrameBody = iFrame.contentDocument.getElementsByTagName('body')[0];
}
else if ( iFrame.contentWindow )
{ // IE
iFrameBody = iFrame.contentWindow.document.getElementsByTagName('body')[0];
}
alert(iFrameBody.innerHTML);
}
An alternative to javax.comm

Old topic, but I think I found another descent solution. Adding class="row"
to a div will result in this CSS configuration:
.row {
display: -webkit-box;
display: flex;
flex-wrap: wrap;
margin-right: -15px;
margin-left: -15px;
}
We want to keep the first 3 rules and we can do this with class="d-flex flex-wrap"
(see https://getbootstrap.com/docs/4.1/utilities/flex/):
.flex-wrap {
flex-wrap: wrap !important;
}
.d-flex {
display: -webkit-box !important;
display: flex !important;
}
It adds !important rules though but it shouldn't be a problem in most cases...
The MySQL function describe table should get you where you want to go (put your table name in for "table"). You'll have to parse the output some, but it's pretty easy. As I recall, if you execute that query, the PHP query result accessing functions that would normally give you a key-value pair will have the column names as the keys. But it's been a while since I used PHP so don't hold me to that. :)
Strace stands out as a tool for investigating production systems where you can't afford to run these programs under a debugger. In particular, we have used strace in the following two situations:

TLDR: Aggregation pipeline is faster as compared to conventional .find().sort()
.
Now moving to the real explanation. There are two ways to perform sorting operations in MongoDB:
.find()
and .sort()
.As suggested by many .find().sort() is the simplest way to perform the sorting.
.sort([("field1",pymongo.ASCENDING), ("field2",pymongo.DESCENDING)])
However, this is a slow process compared to the aggregation pipeline.
Coming to the aggregation pipeline method. The steps to implement simple aggregation pipeline intended for sorting are:
NOTE: In my experience, the aggregation pipeline works a bit faster than the .find().sort()
method.
Here's an example of the aggregation pipeline.
db.collection_name.aggregate([{
"$match": {
# your query - optional step
}
},
{
"$sort": {
"field_1": pymongo.ASCENDING,
"field_2": pymongo.DESCENDING,
....
}
}])
Try this method yourself, compare the speed and let me know about this in the comments.
Edit: Do not forget to use allowDiskUse=True
while sorting on multiple fields otherwise it will throw an error.

I would do this the other way round.
In the OnLoad event for your Main form show the Logon form as a dialog. If the dialog result of that is OK then allow Main to continue loading, if the result is authentication failure then abort the load and show the message box.
EDIT Code sample(s)
private void MainForm_Load(object sender, EventArgs e)
{
this.Hide();
LogonForm logon = new LogonForm();
if (logon.ShowDialog() != DialogResult.OK)
{
//Handle authentication failures as necessary, for example:
Application.Exit();
}
else
{
this.Show();
}
}
Another solution would be to show the LogonForm from the Main method in program.cs, something like this:
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
LogonForm logon = new LogonForm();
Application.Run(logon);
if (logon.LogonSuccessful)
{
Application.Run(new MainForm());
}
}
In this example your LogonForm would have to expose out a LogonSuccessful bool property that is set to true when the user has entered valid credentials
http://www.mediacollege.com/internet/javascript/text/case-capitalize.html is one of many answers out there.
Google can be all you need for such problems.
A naïve approach would be to split the string by whitespace, capitalize the first letter of each element of the resulting array and join it back together. This leaves existing capitalization alone (e.g. HTML stays HTML and doesn't become something silly like Html). If you don't want that affect, turn the entire string into lowercase before splitting it up.
Use the Database menu and "Set Datasource Location" menu option to change the name or location of each table in a report.
This works for changing the location of a database, changing to a new database, and changing the location or name of an individual table being used in your report.
To change the datasource connection, go the Database menu and click Set Datasource Location.
And try running the report again.
The key is to change the datasource connection first, then any tables you need to update, then the other stuff. The connection won't automatically change the tables underneath. Those tables are like goslings that've imprinted on the first large goose-like animal they see. They'll continue to bypass all reason and logic and go to where they've always gone unless you specifically manually change them.
To make it more convenient, here's a tip: You can "Show SQL Query" in the Database menu, and you'll see table names qualified with the database (like "Sales"."dbo"."Customers") for any tables that go straight to a specific database. That might make the hunting easier if you have a lot of stuff going on. When I tackled this problem I had to change each and every table to point to the new table in the new database.
You will need to prevent default form behaviour on submit. After that you will need to submit form programmatically in case of Ok button is selected.
Here is how it could look like:
document.querySelector('#from1').addEventListener('submit', function(e) {
var form = this;
e.preventDefault(); // <--- prevent form from submitting
swal({
title: "Are you sure?",
text: "You will not be able to recover this imaginary file!",
icon: "warning",
buttons: [
'No, cancel it!',
'Yes, I am sure!'
],
dangerMode: true,
}).then(function(isConfirm) {
if (isConfirm) {
swal({
title: 'Shortlisted!',
text: 'Candidates are successfully shortlisted!',
icon: 'success'
}).then(function() {
form.submit(); // <--- submit form programmatically
});
} else {
swal("Cancelled", "Your imaginary file is safe :)", "error");
}
})
});
UPD. Example above uses sweetalert v2.x promise API.
I found Robert Love's Linux Kernel Development quite interesting. It tells you about how the different subsystems in the Linux kernel works in a very down-to-earth way. Since the source is available Linux is a prime candidate for something to hack on.
Deprecated in general means "don't use it".

Here is an example to explain the most simple way of using getter and setter in java. One can do this in a more straightforward way but getter and setter have something special that is when using private member of parent class in child class in inheritance. You can make it possible through using getter and setter.
package stackoverflow;
public class StackoverFlow
{
private int x;
public int getX()
{
return x;
}
public int setX(int x)
{
return this.x = x;
}
public void showX()
{
System.out.println("value of x "+x);
}
public static void main(String[] args) {
StackoverFlow sto = new StackoverFlow();
sto.setX(10);
sto.getX();
sto.showX();
}
}
In getUserById
you shouldn't create a new object (user1) which isn't used. Just assign it to the already (but null) initialized user
. Otherwise Hibernate.initialize(user);
is actually Hibernate.initialize(null);
Here's the new getUserById
(I haven't tested this ;)):
public User getUserById(Long user_id) {
Session session = null;
Object user = null;
try {
session = HibernateUtil.getSessionFactory().openSession();
user = (User)session.load(User.class, user_id);
Hibernate.initialize(user);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (session != null && session.isOpen()) {
session.close();
}
}
return user;
}
For the <input> element there's the maxlength attribute:
<input type="text" id="Textbox" name="Textbox" maxlength="10" />
(by the way, the type is "text", not "textbox" as others are writing), however, you have to use javascript with <textarea>s. Either way the length should be checked on the server anyway.

, i've tested under chrome 52.0.2743.116 m, the result shows that no-cache
has the same behavior as must-revalidate
, they all will NOT use local cache when server is unreachable, and, they all will use cache while tap browser's Back/Forward button when server is unreachable.
As above, i think max-age=0, must-revalidate
is identical to no-cache
, at least in implementation.
stringcase is my go-to library for this; e.g.:
>>> from stringcase import pascalcase, snakecase
>>> snakecase('FooBarBaz')
'foo_bar_baz'
>>> pascalcase('foo_bar_baz')
'FooBarBaz'
If I understand correct you will have something like this:
<input value="default" id="sth" name="sth" type="hidden">
And to get it you have to write:
@Html.HiddenFor(m => m.sth, new { Value = "default" })
for Strongly-typed view.
Markup
<asp:TextBox ID="txtDateOfBirth" runat="server" onkeydown="javascript:preventInput(event);" onpaste="return false;"
TabIndex="1">
Script
function preventInput(evnt) {
//Checked In IE9,Chrome,FireFox
if (evnt.which != 9) evnt.preventDefault();}
