In my case I was developing an ASP.Net MVC5 web app and the certificate errors on my local dev machine (IISExpress certificate) started becoming a practical concern once I started working with service workers. Chrome simply wouldn't register my service worker because of the certificate error.
I did, however, notice that during my automated Selenium browser tests, Chrome seem to just "ignore" all these kinds of problems (e.g. the warning page about an insecure site), so I asked myself the question: How is Selenium starting Chrome for running its tests, and might it also solve the service worker problem?
Using Process Explorer on Windows, I was able to find out the command-line arguments with which Selenium is starting Chrome:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12207 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\Sam\AppData\Local\Temp\some-non-existent-directory" data:,
There are a bunch of parameters here that I didn't end up doing necessity-testing for, but if I run Chrome this way, my service worker registers and works as expected.
The only one that does seem to make a difference is the --user-data-dir parameter, which to make things work can be set to a non-existent directory (things won't work if you don't provide the parameter).
Hope that helps someone else with a similar problem. I'm using Chrome 60.0.3112.90.

You can try the following. Works fine in my case:
Hope that helps.
Recursion is a method that call itself. In this case it is a recursion. However it will be overloading until you put a restriction inside the method to stop the loop (if-condition).
use:
$scope.users.length;
Instead of:
$scope.users.lenght;
And next time "spell-check" your code.
The other answers don't work for me. I'm trying to get the command line working in Jenkins. All you need are the following command line arguments:
--non-interactive

Operators like <=
in Python are generally not overriden to mean something significantly different than "less than or equal to". It's unusual for the standard library does this--it smells like legacy API to me.
Use the equivalent and more clearly-named method, set.issubset
. Note that you don't need to convert the argument to a set; it'll do that for you if needed.
set(['a', 'b']).issubset(['a', 'b', 'c'])
Here's what I would do:
sudo docker ps
sudo docker commit <containerid> <foo/live>
sudo docker run -i -p 22 -p 8000:80 -m /data:/data -t <foo/live> /bin/bash
you can use plt.matshow()
instead of plt.imshow()
or you can use seaborn module's heatmap

Not quite sure why everyone is giving you a hard time for wanting to do this - there are several scenarios where you'd want a fixed size initialised list. And you've correctly deduced that arrays are sensible in these cases.
import array
verts=array.array('i',(0,)*1000)
For the non-pythonistas, the (0,)*1000
term is creating a tuple containing 1000 zeros. The comma forces python to recognise (0)
as a tuple, otherwise it would be evaluated as 0.
I've used a tuple instead of a list because they are generally have lower overhead.
While pure JavaScript is sufficient here, I still prefer the jQuery approach. After all, the ask was to get the hostname using jQuery.
var hostName = $(location).attr('hostname'); // www.example.com
You should use this one :
$('#remote').val(null).trigger("change");
I know it's late answer but I had same problem for last two days, and none of the above solutions worked for me. My app supports min sdk 16, Jelly Bean 4.1.x, so I wanted to test my app on emulator with 16 android api version and I needed Google Play Services.
In short, solution that worked for me is:
- make new emulator Nexus 5X (with Play Store support) - Jelly Bean 4.1.x, 16 API level (WITHOUT Google APIs)
- manually download apks of Google Play Store and Google Play Services (it is necessary that both apks have similar version, they need to start with same number, for example 17.x)
- drag and drop those apks into new emulator
- congratulations you have updated Google Play Services on your 4.1.x emulator
Here are the steps and errors I have encountered during the problem.
So I have made new emulator in my AVD. I picked Nexus 5X (with Play Store support). After that I picked Jelly Bean 16 api level (with Google APIs). When I opened my app dialog pop up with message You need to update your Google play services. When I clicked on Update button, nothing happened. I did update everything necessary in SDK manager, but nothing worked. I didn't have installed Google Play Store on my emulator, even tho I picked Nexus 5X which comes with preinstalled Play Store. So I couldn't find Google Play Store tab in Extended Controls (tree dots next to my emulator).
Because nothings worked, I decided to try to install Google Play Services manually, by downloading APK and dragging it into emulator. When I tried this, I encountered problem The APK failed to install. Error: INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES. I figured that this was the problem because I picked Jelly Bean 16 api level (with Google APIs). So I made new emulator
Nexus 5X (with Play Store support) - Jelly Bean 16 api level (WITHOUT Google APIs)
This allowed me to install my Google Play Service manually. But when I run my app, it still didn't want to open it. Problem was that my emulator was missing Google Play Store. So I installed it manually like Google Play Service. But when it was successfully installed, dialog started popping out every second with message Unfortunately Google Play Services has stopped. Problem was that version of my Google Play Store was 17.x and Google Play Service was 19.x. So at the end I installed Google Play Service with version 17.x, and everything worked.
HERE=$(cd $(dirname $BASH_SOURCE) && pwd)
where you get the full path with new_path=$(dirname ${BASH_SOURCE[0]})
. You change current directory with cd
new_path and then run pwd
to get the full path to the current directory.
As the error message says, non-default argument til
should not follow default argument hgt
.
Changing order of parameters (function call also be adjusted accordingly) or making hgt
non-default parameter will solve your problem.
def a(len1, hgt=len1, til, col=0):
->
def a(len1, hgt, til, col=0):
UPDATE
Another issue that is hidden by the SyntaxError.
os.system
accepts only one string parameter.
def a(len1, hgt, til, col=0):
system('mode con cols=%s lines=%s' % (len1, hgt))
system('title %s' % til)
system('color %s' % col)
For everyone coming to this thread with fractional seconds in your timestamp use:
to_timestamp('2018-11-03 12:35:20.419000', 'YYYY-MM-DD HH24:MI:SS.FF')
This post has been up for 4 years and I still struggled with this conversion problem - so the issue is still active in 2017 in some sense. I was somewhat shocked that the numpy documentation does not readily offer a simple conversion algorithm but that's another story.
I have come across another way to do the conversion that only involves modules numpy
and datetime
, it does not require pandas to be imported which seems to me to be a lot of code to import for such a simple conversion. I noticed that datetime64.astype(datetime.datetime)
will return a datetime.datetime
object if the original datetime64
is in micro-second units while other units return an integer timestamp. I use module xarray
for data I/O from Netcdf files which uses the datetime64
in nanosecond units making the conversion fail unless you first convert to micro-second units. Here is the example conversion code,
import numpy as np
import datetime
def convert_datetime64_to_datetime( usert: np.datetime64 )->datetime.datetime:
t = np.datetime64( usert, 'us').astype(datetime.datetime)
return t
Its only tested on my machine, which is Python 3.6 with a recent 2017 Anaconda distribution. I have only looked at scalar conversion and have not checked array based conversions although I'm guessing it will be good. Nor have I looked at the numpy datetime64 source code to see if the operation makes sense or not.
You can also make it with BufferedReader if you want to validate user input, like this:
import java.io.BufferedReader;
import java.io.InputStreamReader;
class Areas {
public static void main(String args[]){
float PI = 3.1416f;
int r=0;
String rad; //We're going to read all user's text into a String and we try to convert it later
BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); //Here you declare your BufferedReader object and instance it.
System.out.println("Radius?");
try{
rad = br.readLine(); //We read from user's input
r = Integer.parseInt(rad); //We validate if "rad" is an integer (if so we skip catch call and continue on the next line, otherwise, we go to it (catch call))
System.out.println("Circle area is: " + PI*r*r + " Perimeter: " +PI*2*r); //If all was right, we print this
}
catch(Exception e){
System.out.println("Write an integer number"); //This is what user will see if he/she write other thing that is not an integer
Areas a = new Areas(); //We call this class again, so user can try it again
//You can also print exception in case you want to see it as follows:
// e.printStackTrace();
}
}
}
Because Scanner class won't allow you to do it, or not that easy...
And to validate you use "try-catch" calls.
If you want to write the output to a file you can use the stdout-argument of subprocess.call
.
It takes None
, subprocess.PIPE
, a file object or a file descriptor. The first is the default, stdout is inherited from the parent (your script). The second allows you to pipe from one command/process to another. The third and fourth are what you want, to have the output written to a file.
You need to open a file with something like open
and pass the object or file descriptor integer to call
:
f = open("blah.txt", "w")
subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], stdout=f)
I'm guessing any valid file-like object would work, like a socket (gasp :)), but I've never tried.
As marcog mentions in the comments you might want to redirect stderr as well, you can redirect this to the same location as stdout with stderr=subprocess.STDOUT
. Any of the above mentioned values works as well, you can redirect to different places.

HTTPS requires an initial handshake which can be very slow. The actual amount of data transferred as part of the handshake isn't huge (under 5 kB typically), but for very small requests, this can be quite a bit of overhead. However, once the handshake is done, a very fast form of symmetric encryption is used, so the overhead there is minimal. Bottom line: making lots of short requests over HTTPS will be quite a bit slower than HTTP, but if you transfer a lot of data in a single request, the difference will be insignificant.
However, keepalive is the default behaviour in HTTP/1.1, so you will do a single handshake and then lots of requests over the same connection. This makes a significant difference for HTTPS. You should probably profile your site (as others have suggested) to make sure, but I suspect that the performance difference will not be noticeable.
You can use twitter search page to bypass 3,200 limit. However you have to scroll down many times in the search results page. For example, I searched tweets from @beyinsiz_adam. This is the link of search results: https://twitter.com/search?q=from%3Abeyinsiz_adam&src=typd&f=realtime
Now in order to scroll down many times, you can use the following javascript code.
var myVar=setInterval(function(){myTimer()},1000);
function myTimer() {
window.scrollTo(0,document.body.scrollHeight);
}
Just run it in the FireBug console. And wait some time to load all tweets.
As @PavelAnossov answered, the canonical answer, use the word_tokenize
function in nltk:
from nltk import word_tokenize
sent = "This is my text, this is a nice way to input text."
word_tokenize(sent)
If your sentence is truly simple enough:
Using the string.punctuation
set, remove punctuation then split using the whitespace delimiter:
import string
x = "This is my text, this is a nice way to input text."
y = "".join([i for i in x if not in string.punctuation]).split(" ")
print y
Use json_decode to transform your JSON into a PHP array. Example:
$json = '{"a":"b"}';
$array = json_decode($json, true);
echo $array['a']; // b
Like this:
#!/bin/bash
a=2462620
b=2462620
if [ "$a" -eq "$b" ]; then
echo "They're equal";
fi
Integers can be compared with these operators:
-eq # equal
-ne # not equal
-lt # less than
-le # less than or equal
-gt # greater than
-ge # greater than or equal
See this cheatsheet: https://devhints.io/bash#conditionals
The most effective solution that I found is to define the parent element with display:flex
and align-items:center
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<style>
.myclass{
display:flex;
align-items:center;
background-color:grey;
color:#fff;
height:50px;
}
</style>
</head>
<body>
<div class="myclass">
<input type="checkbox">
<label>do you love Ananas?
</label>
</div>
</body>
</html>
OUTPUT:
Write an expect
script.
Here is an example:
#!/usr/bin/expect
#If it all goes pear shaped the script will timeout after 20 seconds.
set timeout 20
#First argument is assigned to the variable name
set name [lindex $argv 0]
#Second argument is assigned to the variable user
set user [lindex $argv 1]
#Third argument is assigned to the variable password
set password [lindex $argv 2]
#This spawns the telnet program and connects it to the variable name
spawn telnet $name
#The script expects login
expect "login:"
#The script sends the user variable
send "$user "
#The script expects Password
expect "Password:"
#The script sends the password variable
send "$password "
#This hands control of the keyboard over to you (Nice expect feature!)
interact
To run:
./myscript.expect name user password
And here is a simple Send-MailMessage
example with username/password for anyone looking for just that
$secpasswd = ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential ("username", $secpasswd)
Send-MailMessage -SmtpServer mysmptp -Credential $cred -UseSsl -From '[email protected]' -To '[email protected]' -Subject 'TEST'
In Laravel 5.6, you will need to set it as
session(['variableName'=>$value]);
To retrieve it is as simple as
$variableName = session('variableName')
EXECUTE dbms_mview.refresh('view name','cf');
Or use awk
for a single process without |
:
awk '/your_regexp/ && NR < 11' INPUTFILE
On each line, if your_regexp
matches, and the number of records (lines) is less than 11, it executes the default action (which is printing the input line).
Or use sed
:
sed -n '/your_regexp/p;10q' INPUTFILE
Checks your regexp and prints the line (-n
means don't print the input, which is otherwise the default), and quits right after the 10th line.
I had the error of
No provider for Router
It happens when you try to navigate in any service.ts
this.router.navigate(['/home']);
like codes in services cause that error.
You should handle navigating in your components. for example: at login.component
login().subscribe(
(res) => this.router.navigate(['/home']),
(error: any) => this.handleError(error));
Annoying errors happens when we are newbie :)
You can use the localeCompare()
method.
string_a.localeCompare(string_b);
/* Expected Returns:
0: exact match
-1: string_a < string_b
1: string_a > string_b
*/
Further Reading:
Apache has 2 types of MPM (Multi-Processing Modules) defined:
1:Prefork 2: Worker
By default, Apacke is configured in preforked mode i.e. non-threaded pre-forking web server. That means that each Apache child process contains a single thread and handles one request at a time. Because of that, it consumes more resources.
Apache also has the worker MPM that turns Apache into a multi-process, multi-threaded web server. Worker MPM uses multiple child processes with many threads each.
Default parameter values must appear on the declaration, since that is the only thing that the caller sees.
EDIT: As others point out, you can have the argument on the definition, but I would advise writing all code as if that wasn't true.
The first visible character is '!' according to ASCII table.And the last one is '~' So "!file.doc" or "~file.doc' will be the top one depending your ranking order. You can check the ascii table here: http://www.asciitable.com/

Interfaces are implemented through classes. They are purely abstract classes, if you will.
In PHP when a class implements from an interface, the methods defined in that interface are to be strictly followed. When a class inherits from a parent class, method parameters may be altered. That is not the case for interfaces:
interface ImplementMeStrictly {
public function foo($a, $b);
}
class Obedient implements ImplementMeStrictly {
public function foo($a, $b, $c)
{
}
}
will cause an error, because the interface wasn't implemented as defined. Whereas:
class InheritMeLoosely {
public function foo($a)
{
}
}
class IDoWhateverWithFoo extends InheritMeLoosely {
public function foo()
{
}
}
Is allowed.
As of powershell 5.0, you can now use the -Depth

There are lot of GUI designers even like Eclipse plugins, just few of them could use both, Swing and SWT..
WindowBuilder Pro GUI Designer - eclipse marketplace
WindowBuilder Pro GUI Designer - Google code home page
and
Jigloo SWT/Swing GUI Builder - eclipse market place
Jigloo SWT/Swing GUI Builder - home page
The window builder is quite better tool..
But IMHO, GUIs created by those tools have really ugly and unmanageable code..
Try these ...
Option1
window.location=document.referrer;
Option2
window.location.reload(history.back());
Using --disable-web-security
switch is quite dangerous! Why disable security at all while you can just allow XMLHttpRequest to access files from other files using --allow-file-access-from-files
switch?
Before using these commands be sure to end all running instances of Chrome.
On Windows:
chrome.exe --allow-file-access-from-files
On Mac:
open /Applications/Google\ Chrome.app/ --args --allow-file-access-from-files
Discussions of this "feature" of Chrome:
You get this error message if a Python file was closed from "the outside", i.e. not from the file object's close()
method:
>>> f = open(".bashrc")
>>> os.close(f.fileno())
>>> del f
close failed in file object destructor:
IOError: [Errno 9] Bad file descriptor
The line del f
deletes the last reference to the file object, causing its destructor file.__del__
to be called. The internal state of the file object indicates the file is still open since f.close()
was never called, so the destructor tries to close the file. The OS subsequently throws an error because of the attempt to close a file that's not open.
Since the implementation of os.system()
does not create any Python file objects, it does not seem likely that the system()
call is the origin of the error. Maybe you could show a bit more code?
I've made small modifications to @paul-H code, such that you can set the font size for the x/y axes and legend independently. Hope it helps:

y = np.random.lognormal(size=37)
# defaults
sns.set()
fig, ax = plt.subplots()
ax.plot(x, y, marker='s', linestyle='none', label='small')
ax.legend(loc='upper left', fontsize=20,bbox_to_anchor=(0, 1.1))
ax.set_xlabel('X_axi',fontsize=20);

Just use .animate()
instead of .css()
(with a duration if you want), like this:
$('#hfont1').hover(function() {
$(this).animate({"color":"#efbe5c","font-size":"52pt"}, 1000);
}, function() {
$(this).animate({"color":"#e8a010","font-size":"48pt"}, 1000);
});
You can test it here. Note though, you need either the jQuery color plugin, or jQuery UI included to animate the color. In the above, the duration is 1000ms, you can change it, or just leave it off for the default 400ms duration.
Windows has two different settings in which priority is established. There is the metric value which you have already set in the adapter settings, and then there is the connection priority in the network connections settings.
To change the priority of the connections:
Here is an update for Swift 3 and an addition to Mani's answer. I would suggest using sender.view
in combination with tagging UIViews (or other elements, depending on what you are trying to track) for a somewhat more "advanced" approach.
let yourTapEvent = UITapGestureRecognizer(target: self, action: #selector(yourController.yourFunction))
yourObject.addGestureRecognizer(yourTapEvent) // adding the gesture to your object
Defining the function in the same testController (that's the name of your View Controller). We are going to use tags here - tags are Int IDs, which you can add to your UIView with yourButton.tag = 1
. If you have a dynamic list of elements like an array you can make a for-loop, which iterates through your array and adds a tag, which increases incrementally
func yourFunction(_ sender: AnyObject) {
let yourTag = sender.view!.tag // this is the tag of your gesture's object
// do whatever you want from here :) e.g. if you have an array of buttons instead of just 1:
for button in buttonsArray {
if(button.tag == yourTag) {
// do something with your button
}
}
}
The reason for all of this is because you cannot pass further arguments for yourFunction when using it in conjunction with #selector.
If you have an even more complex UI structure and you want to get the parent's tag of the item attached to your tap gesture you can use let yourAdvancedTag = sender.view!.superview?.tag
e.g. getting the UIView's tag of a pressed button inside that UIView; can be useful for thumbnail+button lists etc.
Since your desired output is sorted, you also need to sort it:
>>> j=[4, 5, 6, 7, 1, 3, 7, 5]
>>> sorted(x for x in j if x >= 5)
[5, 5, 6, 7, 7]
The method binascii.hexlify()
will convert bytes
to a bytes
representing the ascii hex string. That means that each byte in the input will get converted to two ascii characters. If you want a true str
out then you can .decode("ascii")
the result.
I included an snippet that illustrates it.
import binascii
with open("addressbook.bin", "rb") as f: # or any binary file like '/bin/ls'
in_bytes = f.read()
print(in_bytes) # b'\n\x16\n\x04'
hex_bytes = binascii.hexlify(in_bytes)
print(hex_bytes) # b'0a160a04' which is twice as long as in_bytes
hex_str = hex_bytes.decode("ascii")
print(hex_str) # 0a160a04
from the hex string "0a160a04"
to can come back to the bytes
with binascii.unhexlify("0a160a04")
which gives back b'\n\x16\n\x04'
You can make extension to just change one color component
static class ColorExtension
{
public static Color ChangeG(Color this color,byte g)
{
return Color.FromArgb(color.A,color.R,g,color.B);
}
}
then you can use this:
yourColor = yourColor.ChangeG(100);
In the source root:
git reset ./ HEAD <--un-stage any staged changes
git checkout ./ <--discard any unstaged changes
Here's a hackish solution I discovered:
#image {
max-width: 10%;
max-height: 10%;
transform: scale(10);
}
This will enlarge the image tenfold, but restrict it to 10% of its final size - thus bounding it to the container.
Unlike the background-image
solution, this will also work with <video>
elements.
Interactive example:
function step(timestamp) {
var container = document.getElementById('container');
timestamp /= 1000;
container.style.left = (200 + 100 * Math.sin(timestamp * 1.0)) + 'px';
container.style.top = (200 + 100 * Math.sin(timestamp * 1.1)) + 'px';
container.style.width = (500 + 500 * Math.sin(timestamp * 1.2)) + 'px';
container.style.height = (500 + 500 * Math.sin(timestamp * 1.3)) + 'px';
window.requestAnimationFrame(step);
}
window.requestAnimationFrame(step);

Change the customBinding in the web.config to use larger defaults. I picked 2MB as it is a reasonable size. Of course setting it to 2GB (as your code suggests) will work but it does leave you more vulnerable to attacks. Pick a size that is larger than your largest request but isn't overly large.

For identifying NaN
values use boolean indexing
:
print(df[df['x'].isnull()])
Then for removing all non-numeric values use to_numeric
with parameter errors='coerce'
- to replace non-numeric values to NaN
s:
df['x'] = pd.to_numeric(df['x'], errors='coerce')
And for remove all rows with NaN
s in column x
use dropna
:
df = df.dropna(subset=['x'])
Last convert values to int
s:
df['x'] = df['x'].astype(int)
We all know that PHP save errors in php_errors.log file.
But, that file contains a lot of data.
If we want to log our application data, we need to save it to a custom location.
We can use two parameters in the error_log function to achieve this.
http://php.net/manual/en/function.error-log.php
We can do it using:
error_log(print_r($v, TRUE), 3, '/var/tmp/errors.log');
Where,
print_r($v, TRUE) :
logs $v (array/string/object) to log file.
3
: Put log message to custom log file specified in the third parameter.
'/var/tmp/errors.log'
: Custom log file (This path is for Linux, we can specify other depending upon OS).
OR, you can use file_put_contents()
file_put_contents('/var/tmp/e.log', print_r($v, true), FILE_APPEND);
Where:
'/var/tmp/errors.log':
Custom log file (This path is for Linux, we can specify other depending upon OS).
print_r($v, TRUE) :
logs $v (array/string/object) to log file.
FILE_APPEND: Constant parameter specifying whether to append to the file if it exists, if file does not exist, new file will be created.
Prevent the default behavior of the mousewheel event on input-number elements like suggested by others (calling "blur()" would normally not be the preferred way to do it, because that wouldn't be, what the user wants).
BUT. I would avoid listening for the mousewheel event on all input-number elements all the time and only do it, when the element is in focus (that's when the problem exists). Otherwise the user cannot scroll the page when the mouse pointer is anywhere over a input-number element.
Solution for jQuery:
// disable mousewheel on a input number field when in focus
// (to prevent Cromium browsers change the value when scrolling)
$('form').on('focus', 'input[type=number]', function (e) {
$(this).on('wheel.disableScroll', function (e) {
e.preventDefault()
})
})
$('form').on('blur', 'input[type=number]', function (e) {
$(this).off('wheel.disableScroll')
})
(Delegate focus events to the surrounding form element - to avoid to many event listeners, which are bad for performance.)
<nav class="navbar navbar-toggleable-md navbar-light bg-danger">
So you have this code here, you must be knowing that bg-danger
gives some sort of color.
Now if you want to give some custom color to your page then simply change bg-danger
to bg-color
.
Then either create a separate css-file or you can workout with style
element in same tag
.
Just do this-
`<nav class="navbar navbar-toggleable-md navbar-light bg-color" style="background-color: cyan;">` .
That would do.
You can call Collections.sort() and pass in a Comparator which you need to write to compare different properties of the object.
First off, thanks to @paper1337 for pointing me to the right resources...I'm not registered so I can't vote him up, please do so if anybody else reads this.
Here's how to accomplish what I was trying to do.
Validatable class:
public class ValidateMe : IValidatableObject
{
[Required]
public bool Enable { get; set; }
[Range(1, 5)]
public int Prop1 { get; set; }
[Range(1, 5)]
public int Prop2 { get; set; }
public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
var results = new List<ValidationResult>();
if (this.Enable)
{
Validator.TryValidateProperty(this.Prop1,
new ValidationContext(this, null, null) { MemberName = "Prop1" },
results);
Validator.TryValidateProperty(this.Prop2,
new ValidationContext(this, null, null) { MemberName = "Prop2" },
results);
// some other random test
if (this.Prop1 > this.Prop2)
{
results.Add(new ValidationResult("Prop1 must be larger than Prop2"));
}
}
return results;
}
}
Using Validator.TryValidateProperty()
will add to the results collection if there are failed validations. If there is not a failed validation then nothing will be add to the result collection which is an indication of success.
Doing the validation:
public void DoValidation()
{
var toValidate = new ValidateMe()
{
Enable = true,
Prop1 = 1,
Prop2 = 2
};
bool validateAllProperties = false;
var results = new List<ValidationResult>();
bool isValid = Validator.TryValidateObject(
toValidate,
new ValidationContext(toValidate, null, null),
results,
validateAllProperties);
}
It is important to set validateAllProperties
to false for this method to work. When validateAllProperties
is false only properties with a [Required]
attribute are checked. This allows the IValidatableObject.Validate()
method handle the conditional validations.
You can achieve the solution, by doing this:
JavaScript:
var myValue = document.getElementById("@(ViewBag.CC)").value;
or if you want to use jQuery
, then:
jQuery
var myValue = $('#' + '@(ViewBag.CC)').val();
I've also had this error when trying to pull the changes into a branch which is not created from the upstream branch from which I'm trying to pull.
Eg - This creates a new branch matching night-version
of upstream
git checkout upstream/night-version -b testnightversion
This creates a branch testmaster
in local which matches the master
branch of upstream.
git checkout upstream/master -b testmaster
Now if I try to pull the changes of night-version
into testmaster
branch leads to this error.
git pull upstream night-version //while I'm in `master` cloned branch
I managed to solve this by navigating to proper branch and pull the changes.
git checkout testnightversion
git pull upstream night-version // works fine.
Response you are getting is in object form i.e.
{
"dstOffset" : 3600,
"rawOffset" : 36000,
"status" : "OK",
"timeZoneId" : "Australia/Hobart",
"timeZoneName" : "Australian Eastern Daylight Time"
}
Replace below line of code :
List<Post> postsList = Arrays.asList(gson.fromJson(reader,Post.class))
with
Post post = gson.fromJson(reader, Post.class);

To find where Anaconda was installed I used the "where" command on the command line in Windows.
C:\>where anaconda
which for me returned:
C:\Users\User-Name\AppData\Local\Continuum\Anaconda2\Scripts\anaconda.exe
Which allowed me to find the Anaconda Python interpreter at
C:\Users\User-Name\AppData\Local\Continuum\Anaconda2\python.exe

I want to understand the lock each transaction isolation takes on the table
For example, you have 3 concurrent processes A, B and C. A starts a transaction, writes data and commit/rollback (depending on results). B just executes a SELECT
statement to read data. C reads and updates data. All these process work on the same table T.
WHERE aField > 10 AND aField < 20
, A inserts data where aField
value is between 10 and 20, then B reads the data again and get a different result.I want to understand where we define these isolation levels: only at JDBC/hibernate level or in DB also
Using JDBC, you define it using Connection#setTransactionIsolation
.
Using Hibernate:
<property name="hibernate.connection.isolation">2</property>
Where
Hibernate configuration is taken from here (sorry, it's in Spanish).
By the way, you can set the isolation level on RDBMS as well:
SET ISOLATION TO DIRTY READ
sentence.)and on and on...
NOTE: This should be considered a discussion rather than an actual answer.
An approximate approach is to operate __main__
in the module you want to create variables. For example there's a b.py
:
#!/usr/bin/env python
# coding: utf-8
def set_vars():
import __main__
print '__main__', __main__
__main__.B = 1
try:
print B
except NameError as e:
print e
set_vars()
print 'B: %s' % B
Running it would output
$ python b.py
name 'B' is not defined
__main__ <module '__main__' from 'b.py'>
B: 1
But this approach only works in a single module script, because the __main__
it import will always represent the module of the entry script being executed by python, this means that if b.py
is involved by other code, the B
variable will be created in the scope of the entry script instead of in b.py
itself. Assume there is a script a.py
:
#!/usr/bin/env python
# coding: utf-8
try:
import b
except NameError as e:
print e
print 'in a.py: B', B
Running it would output
$ python a.py
name 'B' is not defined
__main__ <module '__main__' from 'a.py'>
name 'B' is not defined
in a.py: B 1
Note that the __main__
is changed to 'a.py'
.
With CSS3 we can easily adjust an image. But remember this does not change the image. It only displays the adjusted image.
See the following code for more details.
To make an image gray:
img {
-webkit-filter: grayscale(100%);
-moz-filter: grayscale(100%);
}
To give a sepia look:
img {
-webkit-filter: sepia(100%);
-moz-filter: sepia(100%);
}
To adjust brightness:
img {
-webkit-filter: brightness(50%);
-moz-filter: brightness(50%);
}
To adjust contrast:
img {
-webkit-filter: contrast(200%);
-moz-filter: contrast(200%);
}
To Blur an image:
img {
-webkit-filter: blur(10px);
-moz-filter: blur(10px);
}
On a mac you can also use command Z and that will go undo. I'm not sure why, but sometimes it stops, and if your like me and vimtutor is on the bottom of that long list of things you need to learn, than u can just close the window and reopen it and should work fine.
If you are looking for a custom configuration section like following
<CustomApplicationConfig>
<Credentials Username="itsme" Password="mypassword"/>
<PrimaryAgent Address="10.5.64.26" Port="3560"/>
<SecondaryAgent Address="10.5.64.7" Port="3570"/>
<Site Id="123" />
<Lanes>
<Lane Id="1" PointId="north" Direction="Entry"/>
<Lane Id="2" PointId="south" Direction="Exit"/>
</Lanes>
</CustomApplicationConfig>
then you can use my implementation of configuration section so to get started add System.Configuration
assembly reference to your project
Look at the each nested elements I used, First one is Credentials with two attributes so lets add it first
Credentials Element
public class CredentialsConfigElement : System.Configuration.ConfigurationElement
{
[ConfigurationProperty("Username")]
public string Username
{
get
{
return base["Username"] as string;
}
}
[ConfigurationProperty("Password")]
public string Password
{
get
{
return base["Password"] as string;
}
}
}
PrimaryAgent and SecondaryAgent
Both has the same attributes and seem like a Address to a set of servers for a primary and a failover, so you just need to create one element class for both of those like following
public class ServerInfoConfigElement : ConfigurationElement
{
[ConfigurationProperty("Address")]
public string Address
{
get
{
return base["Address"] as string;
}
}
[ConfigurationProperty("Port")]
public int? Port
{
get
{
return base["Port"] as int?;
}
}
}
I'll explain how to use two different element with one class later in this post, let us skip the SiteId as there is no difference in it. You just have to create one class same as above with one property only. let us see how to implement Lanes collection
it is splitted in two parts first you have to create an element implementation class then you have to create collection element class
LaneConfigElement
public class LaneConfigElement : ConfigurationElement
{
[ConfigurationProperty("Id")]
public string Id
{
get
{
return base["Id"] as string;
}
}
[ConfigurationProperty("PointId")]
public string PointId
{
get
{
return base["PointId"] as string;
}
}
[ConfigurationProperty("Direction")]
public Direction? Direction
{
get
{
return base["Direction"] as Direction?;
}
}
}
public enum Direction
{
Entry,
Exit
}
you can notice that one attribute of LanElement
is an Enumeration and if you try to use any other value in configuration which is not defined in Enumeration application will throw an System.Configuration.ConfigurationErrorsException
on startup. Ok lets move on to Collection Definition
[ConfigurationCollection(typeof(LaneConfigElement), AddItemName = "Lane", CollectionType = ConfigurationElementCollectionType.BasicMap)]
public class LaneConfigCollection : ConfigurationElementCollection
{
public LaneConfigElement this[int index]
{
get { return (LaneConfigElement)BaseGet(index); }
set
{
if (BaseGet(index) != null)
{
BaseRemoveAt(index);
}
BaseAdd(index, value);
}
}
public void Add(LaneConfigElement serviceConfig)
{
BaseAdd(serviceConfig);
}
public void Clear()
{
BaseClear();
}
protected override ConfigurationElement CreateNewElement()
{
return new LaneConfigElement();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((LaneConfigElement)element).Id;
}
public void Remove(LaneConfigElement serviceConfig)
{
BaseRemove(serviceConfig.Id);
}
public void RemoveAt(int index)
{
BaseRemoveAt(index);
}
public void Remove(String name)
{
BaseRemove(name);
}
}
you can notice that I have set the AddItemName = "Lane"
you can choose whatever you like for your collection entry item, i prefer to use "add" the default one but i changed it just for the sake of this post.
Now all of our nested Elements have been implemented now we should aggregate all of those in a class which has to implement System.Configuration.ConfigurationSection
CustomApplicationConfigSection
public class CustomApplicationConfigSection : System.Configuration.ConfigurationSection
{
private static readonly ILog log = LogManager.GetLogger(typeof(CustomApplicationConfigSection));
public const string SECTION_NAME = "CustomApplicationConfig";
[ConfigurationProperty("Credentials")]
public CredentialsConfigElement Credentials
{
get
{
return base["Credentials"] as CredentialsConfigElement;
}
}
[ConfigurationProperty("PrimaryAgent")]
public ServerInfoConfigElement PrimaryAgent
{
get
{
return base["PrimaryAgent"] as ServerInfoConfigElement;
}
}
[ConfigurationProperty("SecondaryAgent")]
public ServerInfoConfigElement SecondaryAgent
{
get
{
return base["SecondaryAgent"] as ServerInfoConfigElement;
}
}
[ConfigurationProperty("Site")]
public SiteConfigElement Site
{
get
{
return base["Site"] as SiteConfigElement;
}
}
[ConfigurationProperty("Lanes")]
public LaneConfigCollection Lanes
{
get { return base["Lanes"] as LaneConfigCollection; }
}
}
Now you can see that we have two properties with name PrimaryAgent
and SecondaryAgent
both have the same type now you can easily understand why we had only one implementation class against these two element.
Before you can use this newly invented configuration section in your app.config (or web.config) you just need to tell you application that you have invented your own configuration section and give it some respect, to do so you have to add following lines in app.config (may be right after start of root tag).
<configSections>
<section name="CustomApplicationConfig" type="MyNameSpace.CustomApplicationConfigSection, MyAssemblyName" />
</configSections>
NOTE: MyAssemblyName should be without .dll e.g. if you assembly file name is myDll.dll then use myDll instead of myDll.dll
to retrieve this configuration use following line of code any where in your application
CustomApplicationConfigSection config = System.Configuration.ConfigurationManager.GetSection(CustomApplicationConfigSection.SECTION_NAME) as CustomApplicationConfigSection;
I hope above post would help you to get started with a bit complicated kind of custom config sections.
Happy Coding :)
****Edit****
To Enable LINQ on LaneConfigCollection
you have to implement IEnumerable<LaneConfigElement>
And Add following implementation of GetEnumerator
public new IEnumerator<LaneConfigElement> GetEnumerator()
{
int count = base.Count;
for (int i = 0; i < count; i++)
{
yield return base.BaseGet(i) as LaneConfigElement;
}
}
for the people who are still confused about how yield really works read this nice article
Two key points taken from above article are
it doesn’t really end the method’s execution. yield return pauses the method execution and the next time you call it (for the next enumeration value), the method will continue to execute from the last yield return call. It sounds a bit confusing I think… (Shay Friedman)
Yield is not a feature of the .Net runtime. It is just a C# language feature which gets compiled into simple IL code by the C# compiler. (Lars Corneliussen)
I have tested it (Chrome) and it working for me( both [^]
and [^\0]
), by changing the dot (.
) by either [^\0]
or [^]
, because dot doesn't match line break (See here: http://www.regular-expressions.info/dot.html).
var ss= "<pre>aaaa\nbbb\nccc</pre>ddd";_x000D_
var arr= ss.match( /<pre[^\0]*?<\/pre>/gm );_x000D_
alert(arr); //Working
_x000D_
The problem is that the second part of your substring argument is including the first index. You need to subtract the first index from your second index to make this work.
SELECT SUBSTRING(@Text, CHARINDEX('the dog', @Text)
, CHARINDEX('immediately',@text) - CHARINDEX('the dog', @Text) + Len('immediately'))
list multiplication works.
>>> [0] * 10
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
If you're using spritesheets this becomes impossible and the element must be wrapped.
.btn{
display: inline-block;

You need to understand that a Git repository is not just a tree of directories and files, but also stores a history of those trees - which might contain branches and merges.
When fetching from a repository, you will copy all or some of the branches there to your repository. These are then in your repository as "remote tracking branches", e.g. branches named like remotes/origin/master
or such.
Fetching new commits from the remote repository will not change anything about your local working copy.
Your working copy has normally a commit checked out, called HEAD
. This commit is usually the tip of one of your local branches.
I think you want to update your local branch (or maybe all the local branches?) to the corresponding remote branch, and then check out the latest branch.
To avoid any conflicts with your working copy (which might have local changes), you first clean everything which is not versioned (using git clean
). Then you check out the local branch corresponding to the remote branch you want to update to, and use git reset
to switch it to the fetched remote branch. (git pull
will incorporate all updates of the remote branch in your local one, which might do the same, or create a merge commit if you have local commits.)
(But then you will really lose any local changes - both in working copy and local commits. Make sure that you really want this - otherwise better use a new branch, this saves your local commits. And use git stash
to save changes which are not yet committed.)
Edit: If you have only one local branch and are tracking one remote branch, all you need to do is
git pull
from inside the working directory.
This will fetch the current version of all tracked remote branches and update the current branch (and the working directory) to the current version of the remote branch it is tracking.
This is working for me, you might change your code like this
var responseData=x.toString();
to
var responseData=x.toString("binary");
and finally
response.write(new Buffer(toTransmit, "binary"));
dplyr since 0.4 implemented all those joins including outer_join
, but it was worth noting that for the first few releases prior to 0.4 it used not to offer outer_join
, and as a result there was a lot of really bad hacky workaround user code floating around for quite a while afterwards (you can still find such code in SO, Kaggle answers, github from that period. Hence this answer still serves a useful purpose.)
Join-related release highlights:
v0.1.3 (4/2014)
Workarounds per hadley's comments in that issue:
Try this
<div class="row row-offcanvas row-offcanvas-right">
<div class="col-xs-6 col-sm-3 sidebar-offcanvas" id="sidebar" role="navigation">Nav Content</div>
<div class="col-xs-12 col-sm-9">Content goes here</div>
</div>
This uses Bootstrap 3 so no need for extra CSS etc...
Best Option I could find is Git Windows Just install it and then right click on and click "Git Bash Here" this will open a bash window
This will open a bash window like this:
and the linux commands work...
I've tried 'sh' , 'vi' , 'ssh' , 'curl' ,etc... commands
For Mountain Lion, Apple's java is up to 1.6.0_35-b10-428.jdk as of today.
It is indeed located under /Library/Java/JavaVirtualMachines .
You just download
"Java for OS X 2012-005 Developer Package" (Sept 6, 2012)
from
http://connect.apple.com/
In my view, Apple's naming is at least a bit confusing; why "-005" - is this the fifth version, or the fifth of five installers one needs?
And then run the installer; then follow the above steps inside Eclipse.
Here is a working solution:
#include <stdio.h>
#include <string.h>
int main(int argc, char** argv)
{
char str1[16];
char str2[16];
strcpy(str1, "sssss");
strcpy(str2, "kkkk");
strcat(str1, str2);
printf("%s", str1);
return 0;
}
Output:
ssssskkkk
You have to allocate memory for your strings. In the above code, I declare str1
and str2
as character arrays containing 16 characters. I used strcpy
to copy characters of string literals into them, and strcat
to append the characters of str2
to the end of str1
. Here is how these character arrays look like during the execution of the program:
After declaration (both are empty):
str1: [][][][][][][][][][][][][][][][][][][][]
str2: [][][][][][][][][][][][][][][][][][][][]
After calling strcpy (\0 is the string terminator zero byte):
str1: [s][s][s][s][s][\0][][][][][][][][][][][][][][]
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]
After calling strcat:
str1: [s][s][s][s][s][k][k][k][k][\0][][][][][][][][][][]
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]

First Way:
You didn't create the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Second way:
You created an empty file with the desired name, which then prevented you from creating the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Third way:
You didn't create the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Fourth Way:
You didn't create the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Fifth way:
You didn't create the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Correct way:
File
for your desired directory (e.g., File path=new File(getFilesDir(),"myfolder");
)mkdirs()
on that File
to create the directory if it does not existFile
for the output file (e.g., File mypath=new File(path,"myfile.txt");
)File
(e.g., using new BufferedWriter(new FileWriter(mypath))
)It's probably the same problem with cultures as presented in this related SO-thread: Why can't DateTime.ParseExact() parse "9/1/2009" using "M/d/yyyy"
You already specified the culture, so try escaping the slashes.

Note: I found this question (varchar(255) v tinyblob v tinytext), which says that VARCHAR(n) requires n+1 bytes of storage for n<=255, n+2 bytes of storage for n>255. Is this the only reason? That seems kind of arbitrary, since you would only be saving two bytes compared to VARCHAR(256), and you could just as easily save another two bytes by declaring it VARCHAR(253).
No. you don't save two bytes by declaring 253. The implementation of the varchar is most likely a length counter and a variable length, nonterminated array. This means that if you store "hello" in a varchar(255) you will occupy 6 bytes: one byte for the length (the number 5) and 5 bytes for the five letters.

In case the jobs are grouped it's possible to either give it a full name with forward slashes:
getItemByFullName("folder_name/job_name")
job.getBuilds().each { it.delete() }
job.nextBuildNumber = 1
job.save()
or traverse the hierarchy like this:
def folder = Jenkins.instance.getItem("folder_name")
def job = folder.getItem("job_name")
job.getBuilds().each { it.delete() }
job.nextBuildNumber = 1
job.save()
Solution:
ul li:before {
font-family: 'FontAwesome';
content: '\f067';
margin:0 5px 0 -15px;

Here's a blog post which explains this technique in-depth.
In my experience, openssl always being troublesome, I tried the second method suggested by facebook. And it's wonderful. This is the best method to get the hash key.
Second option is to print out the key hash sent to Facebook and use that value. Make the following changes to the onCreate() method in your main activity:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
PackageInfo info = getPackageManager().getPackageInfo(
"com.facebook.samples.loginhowto",
PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
...other operations
}//end of onCreate
Replace com.facebook.samples.loginhowto with your own package name ( package name in Manifest.xml).
Official link - https://developers.facebook.com/docs/android/login-with-facebook/ ( See the bottom of the page)
openssl
folderopenssl
folder in C:
drivebin
of openssl
i.e C:\openssl\bin
in command promptrun the following command to generate your keyhash. While generating hashkey it should ask you password.
keytool -exportcert -alias androiddebugkey -keystore "C:\Users\Anhsirk.android\debug.keystore" | openssl sha1 -binary | openssl base64
NOTE: in the above code note that , you need to give your path to user ( i.e in my case it is C:\Users\Anhsirk , you just need to change this for your user account.
Give password as android
. If it don’t ask for password your keystore path is incorrect.
If everything works fine, it should give you the hashkey below.
1. Installing OpenCV 2.4.3
First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\
.
Wait until all files get extracted. It will create a new directory C:\opencv
which
contains OpenCV header files, libraries, code samples, etc.
Now you need to add the directory C:\opencv\build\x86\vc10\bin
to your system PATH. This directory contains OpenCV DLLs required for running your code.
Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...
On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin;
(3), then click Ok.
On some computers, you may need to restart your computer for the system to recognize the environment path variables.
This will completes the OpenCV 2.4.3 installation on your computer.
2. Create a new project and set up Visual C++
Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest
) and set the project location (e.g: c:\projects
).
Click Ok. Visual C++ will create an empty project.
Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest
and select Properties → VC++ Directories.
Select Include Directories to add a new entry and type C:\opencv\build\include
.
Click Ok to close the dialog.
Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib
.
Click Ok to close the dialog.
Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:
opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib
Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).
Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.
NOTE:
These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:
opencv_core243.lib
opencv_imgproc243.lib
...
instead of:
opencv_core243d.lib
opencv_imgproc243d.lib
...
You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.
Name your file (e.g: loadimg.cpp
) and click Ok. Type the code below in the editor:
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main()
{
Mat im = imread("c:/full/path/to/lena.jpg");
if (im.empty())
{
cout << "Cannot load image!" << endl;
return -1;
}
imshow("Image", im);
waitKey(0);
}
The code above will load c:\full\path\to\lena.jpg
and display the image. You can
use any image you like, just make sure the path to the image is correct.
Type F5 to compile the code, and it will display the image in a nice window.
And that is your first OpenCV program!
3. Where to go from here?
Now that your OpenCV environment is ready, what's next?
c:\opencv\samples\cpp
.If you would like to handle quotes:
sudo -s -- <<EOF
id
pwd
echo "Done."
EOF
Check your migration file, maybe you are using Schema::table, like this:
Schema::table('table_name', function ($table) {
// ...
});
If you want to create a new table you must use Schema::create:
Schema::create('table_name', function ($table) {
// ...
});
I just created some directories, shared them and mapped using:
net use y: "\\mycomputername\folder with spaces"
So this solution gets "works on my machine" certificate. What error code do you get?

no-store
should not be necessary in normal situations, and can harm both speed and usability. It is intended for use where the HTTP response contains information so sensitive it should never be written to a disk cache at all, regardless of the negative effects that creates for the user.
How it works:
Normally, even if a user agent such as a browser determines that a response shouldn't be cached, it may still store it to the disk cache for reasons internal to the user agent. This version may be utilised for features like "view source", "back", "page info", and so on, where the user hasn't necessarily requested the page again, but the browser doesn't consider it a new page view and it would make sense to serve the same version the user is currently viewing.
Using no-store
will prevent that response being stored, but this may impact the browser's ability to give "view source", "back", "page info" and so on without making a new, separate request for the server, which is undesirable. In other words, the user may try viewing the source and if the browser didn't keep it in memory, they'll either be told this isn't possible, or it will cause a new request to the server. Therefore, no-store
should only be used when the impeded user experience of these features not working properly or quickly is outweighed by the importance of ensuring content is not stored in the cache.
My current understanding is that it is just for intermediate cache server. Even if "no-cache" is in response, intermediate cache server can still save the content to non-volatile storage.
This is incorrect. Intermediate cache servers compatible with HTTP 1.1 will obey the no-cache
and must-revalidate
instructions, ensuring that content is not cached. Using these instructions will ensure that the response is not cached by any intermediate cache, and that all subsequent requests are sent back to the origin server.
If the intermediate cache server does not support HTTP 1.1, then you will need to use Pragma: no-cache
and hope for the best. Note that if it doesn't support HTTP 1.1 then no-store
is irrelevant anyway.
In Notepad++ to replace, hit Ctrl+H to open the Replace menu.
Then if you check the "Regular expression" button and you want in your replacement to use a part of your matching pattern, you must use "capture groups" (read more on google). For example, let's say that you want to match each of the following lines
value="4"
value="403"
value="200"
value="201"
value="116"
value="15"
using the .*"\d+"
pattern and want to keep only the number. You can then use a capture group in your matching pattern, using parentheses (
and )
, like that: .*"(\d+)"
. So now in your replacement you can simply write $1
, where $1 references to the value of the 1st capturing group and will return the number for each successful match. If you had two capture groups, for example (.*)="(\d+)"
, $1
will return the string value
and $2
will return the number.
So by using:
Find: .*"(\d+)"
Replace: $1
It will return you
4
403
200
201
116
15
Please note that there many alternate and better ways of matching the aforementioned pattern. For example the pattern value="([0-9]+)"
would be better, since it is more specific and you will be sure that it will match only these lines. It's even possible of making the replacement without the use of capture groups, but this is a slightly more advanced topic, so I'll leave it for now :)
You can also use
re.findall(r"\[([A-Za-z0-9_]+)\]", string)
if there are many occurrences that you would like to find.

If you are not using jQuery then I would simply write a validation method that you can be fired when the form is submitted. The method can validate the text fields to make sure that they are not empty or the default value. The method will return a bool value and if it is false you can fire off your alert and assign classes to highlight the fields that did not pass validation.
HTML:
<form name="form1" method="" action="" onsubmit="return validateForm(this)">
<input type="text" name="name" value="Name"/><br />
<input type="text" name="addressLine01" value="Address Line 1"/><br />
<input type="submit"/>
</form>
JavaScript:
function validateForm(form) {
var nameField = form.name;
var addressLine01 = form.addressLine01;
if (isNotEmpty(nameField)) {
if(isNotEmpty(addressLine01)) {
return true;
{
{
return false;
}
function isNotEmpty(field) {
var fieldData = field.value;
if (fieldData.length == 0 || fieldData == "" || fieldData == fieldData) {
field.className = "FieldError"; //Classs to highlight error
alert("Please correct the errors in order to continue.");
return false;
} else {
field.className = "FieldOk"; //Resets field back to default
return true; //Submits form
}
}
The validateForm method assigns the elements you want to validate and then in this case calls the isNotEmpty method to validate if the field is empty or has not been changed from the default value. it continuously calls the inNotEmpty method until it returns a value of true or if the conditional fails for that field it will return false.
Give this a shot and let me know if it helps or if you have any questions. of course you can write additional custom methods to validate numbers only, email address, valid URL, etc.
If you use jQuery at all I would look into trying out the jQuery Validation plug-in. I have been using it for my last few projects and it is pretty nice. Check it out if you get a chance. http://docs.jquery.com/Plugins/Validation
Android studio is based on Intellij Idea. In Intellij Idea you have to do the following from the GUI menu.

This is what worked for our particular situation.
Notes are from Wikipedia on Basic Auth from the Client Side. Thank you to @briantist's answer for the help!
Combine the username and password into a single string username:password
$user = "shaunluttin"
$pass = "super-strong-alpha-numeric-symbolic-long-password"
$pair = "${user}:${pass}"
Encode the string to the RFC2045-MIME variant of Base64, except not limited to 76 char/line.
$bytes = [System.Text.Encoding]::ASCII.GetBytes($pair)
$base64 = [System.Convert]::ToBase64String($bytes)
Create the Auth value as the method, a space, and then the encoded pair Method Base64String
$basicAuthValue = "Basic $base64"
Create the header Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
$headers = @{ Authorization = $basicAuthValue }
Invoke the web-request
Invoke-WebRequest -uri "https://api.github.com/user" -Headers $headers
The PowerShell version of this is more verbose than the cURL version is. Why is that? @briantist pointed out that GitHub is breaking the RFC and PowerShell is sticking to it. Does that mean that cURL is also breaking with the standard?
You are using a relative path. You should use the absolute path, url(/assets/css/style.css).
If using a StackTraceElement, use:
String fullClassName = stackTraceElement.getClassName();
String simpleClassName = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);
System.out.println(simpleClassName);
From python tutorial:
Degenerate slice indices are handled gracefully: an index that is too large is replaced by the string size, an upper bound smaller than the lower bound returns an empty string.
So it is safe to use x[:100]
.

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.
If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.
If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).
JToken
is the base class for JObject
, JArray
, JProperty
, JValue
, etc. You can use the Children<T>()
method to get a filtered list of a JToken's children that are of a certain type, for example JObject
. Each JObject
has a collection of JProperty
objects, which can be accessed via the Properties()
method. For each JProperty
, you can get its Name
. (Of course you can also get the Value
if desired, which is another JToken
.)
Putting it all together we have:
JArray array = JArray.Parse(json);
foreach (JObject content in array.Children<JObject>())
{
foreach (JProperty prop in content.Properties())
{
Console.WriteLine(prop.Name);
}
}
Output:
MobileSiteContent
PageContent
If I understand the question, you want to change the value of the checkbox depending if it is checked or not.
Here is one solution:
$('#checkbox-value').text($('#checkbox1').val());_x000D_
_x000D_
$("#checkbox1").on('change', function() {_x000D_
if ($(this).is(':checked')) {_x000D_
$(this).attr('value', 'true');_x000D_
} else {_x000D_
$(this).attr('value', 'false');_x000D_
}_x000D_
_x000D_
$('#checkbox-value').text($('#checkbox1').val());_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<input type="checkbox" name="acceptRules" class="inline checkbox" id="checkbox1" value="false">_x000D_
_x000D_
<div id="checkbox-value"></div>
_x000D_
As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.
It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.
library(grid)
library(gridExtra)
library(plyr)
# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))
# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") +
xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category))
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") +
labs(title = "Proportion of total Frequency accounted by each Category in given Year")
# bring them together
grid.arrange(totals,proportion)
This will give you a 2 panel display like this:
If you want to add Frequency values a table is the best format.
The second for loop is any easy way to iterate over the contents of an array, without having to manually specify the number of items in the array(manual enumeration). It is much more convenient than the first when dealing with arrays.
Here's how to do it from a csv:
import numpy as np
import matplotlib.pyplot as plt
from scipy.interpolate import griddata
# Load data from CSV
dat = np.genfromtxt('dat.xyz', delimiter=' ',skip_header=0)
X_dat = dat[:,0]
Y_dat = dat[:,1]
Z_dat = dat[:,2]
# Convert from pandas dataframes to numpy arrays
X, Y, Z, = np.array([]), np.array([]), np.array([])
for i in range(len(X_dat)):
X = np.append(X, X_dat[i])
Y = np.append(Y, Y_dat[i])
Z = np.append(Z, Z_dat[i])
# create x-y points to be used in heatmap
xi = np.linspace(X.min(), X.max(), 1000)
yi = np.linspace(Y.min(), Y.max(), 1000)
# Interpolate for plotting
zi = griddata((X, Y), Z, (xi[None,:], yi[:,None]), method='cubic')
# I control the range of my colorbar by removing data
# outside of my range of interest
zmin = 3
zmax = 12
zi[(zi<zmin) | (zi>zmax)] = None
# Create the contour plot
CS = plt.contourf(xi, yi, zi, 15, cmap=plt.cm.rainbow,
vmax=zmax, vmin=zmin)
plt.colorbar()
plt.show()
where dat.xyz
is in the form
x1 y1 z1
x2 y2 z2
...
If you manually write out the query with static date values (e.g. '2009-10-29 13:13:07.440') do you get any rows?
So, you are saying that the following two queries produce correct results:
SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat
INNER JOIN PubAdvertiser AS pa
ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > '2009-10-29 13:13:07.440') AND (pa.AdvertiserID = 12345))
DECLARE @sp_Date DATETIME
SET @sp_Date = '2009-10-29 13:13:07.440'
SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat
INNER JOIN PubAdvertiser AS pa
ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > @sp_Date) AND (pa.AdvertiserID = 12345))
I had a similar problem:
docker: Error response from daemon: OCI runtime create failed: container_linux.go:346: starting container process caused "exec: \"sh\": executable file not found in $PATH": unknown.
In my case, I know the image works in other places, then was a corrupted local image.
I solved the issue removing the image (docker rmi <imagename>
) and pulling it again(docker pull <imagename>
).
I did a docker system prune
too, but I think it's not mandatory.
You could also use box-shadow
property with higher value of blur and rgba()
color to set opacity level.
Sounds like a better choice in your case.
box-shadow: 0 30px 40px rgba(0,0,0,.1);
I got the same error, when I was trying to import matplotlib.pyplot
In [1]: import matplotlib.pyplot as plt
...
...
ImportError: No module named PyQt4.QtCore
But in my case the problem was due to a missing linux library libGL.so.1
OS : Cent OS 64 bit
Python version : 3.5.2
$> locate libGL.so.1
If this command returns a value, your problem could be different, so please ignore my answer. If it does not return any value and your environment is same as mine, below steps would fix your problem.
$> yum install mesa-libGL.x86_64
This installs the necessary OpenGL libraries for 64 bit Cent OS.
$> locate libGL.so.1
/usr/lib/libGL.so.1
Now go back to iPython and try to import
In [1]: import matplotlib.pyplot as plt
This time it imported successfully.

As this question notes, messages to nil
are valid in Objective-C. Whilst this is frequently an advantage -- leading to cleaner and more natural code -- the feature can occasionally lead to peculiar and difficult-to-track-down bugs if you get a nil
value when you weren't expecting it.
Is this issue resolved.
I am getting this error: ERROR in node_modules/ngx-restangular/lib/ngx-restangular-http.d.ts(3,27): error TS2307: Cannot find module '@angular/common/http/src/response'.
After updating my angular to version=8
Since PopupWindow
just adds a View
to WindowManager
you can use updateViewLayout (View view, ViewGroup.LayoutParams params)
to update the LayoutParams
of your PopupWindow
's contentView
after calling show..().
Setting the window flag FLAG_DIM_BEHIND
will dimm everything behind the window. Use dimAmount
to control the amount of dim (1.0 for completely opaque to 0.0 for no dim).
Keep in mind that if you set a background to your PopupWindow
it will put your contentView
into a container, which means you need to update it's parent.
With background:
PopupWindow popup = new PopupWindow(contentView, width, height);
popup.setBackgroundDrawable(background);
popup.showAsDropDown(anchor);
View container = (View) popup.getContentView().getParent();
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams) container.getLayoutParams();
// add flag
p.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.3f;
wm.updateViewLayout(container, p);
Without background:
PopupWindow popup = new PopupWindow(contentView, width, height);
popup.setBackgroundDrawable(null);
popup.showAsDropDown(anchor);
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams) contentView.getLayoutParams();
// add flag
p.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.3f;
wm.updateViewLayout(contentView, p);
Marshmallow Update:
On M PopupWindow wraps the contentView inside a FrameLayout called mDecorView. If you dig into the PopupWindow source you will find something like createDecorView(View contentView)
.The main purpose of mDecorView is to handle event dispatch and content transitions, which are new to M. This means we need to add one more .getParent() to access the container.
With background that would require a change to something like:
View container = (View) popup.getContentView().getParent().getParent();
Better alternative for API 18+
A less hacky solution using ViewGroupOverlay
:
1) Get a hold of the desired root layout
ViewGroup root = (ViewGroup) getWindow().getDecorView().getRootView();
2) Call applyDim(root, 0.5f);
or clearDim()
public static void applyDim(@NonNull ViewGroup parent, float dimAmount){
Drawable dim = new ColorDrawable(Color.BLACK);
dim.setBounds(0, 0, parent.getWidth(), parent.getHeight());
dim.setAlpha((int) (255 * dimAmount));
ViewGroupOverlay overlay = parent.getOverlay();
overlay.add(dim);
}
public static void clearDim(@NonNull ViewGroup parent) {
ViewGroupOverlay overlay = parent.getOverlay();
overlay.clear();
}
def function(arg)->123:
It's simply a return type, integer in this case doesn't matter which number you write.
like Java :
public int function(int args){...}
But for Python (how Jim Fasarakis Hilliard said) the return type it's just an hint, so it's suggest the return but allow anyway to return other type like a string..
You may be overcomplicating things, is there any reason you need the stringr package?
df <- data.frame(Date = c("10/9/2009 0:00:00", "10/15/2009 0:00:00"))
as.Date(df$Date, "%m/%d/%Y %H:%M:%S")
[1] "2009-10-09" "2009-10-15"
More generally and if you need the time component as well, use strptime:
strptime(df$Date, "%m/%d/%Y %H:%M:%S")
I'm guessing at what your actual data might look at from the partial results you give.
We got around this by adding functions to the environment
step, i.e.:
environment {
ENVIRONMENT_NAME = defineEnvironment()
}
...
def defineEnvironment() {
def branchName = "${env.BRANCH_NAME}"
if (branchName == "master") {
return 'staging'
}
else {
return 'test'
}
}
A quick, clean approach using very little JS and CSS padding: http://jsfiddle.net/benjamincharity/ZcTsT/14/
var headerHeight = $('#header').height(),
footerHeight = $('#footer').height();
$('#content').css({
'padding-top': headerHeight,
'padding-bottom': footerHeight
});
There the problem : I need to generate html code from the contain of a given div. Then, I have to put this raw html code in a textarea. When I use the function $(textarea).val()
like this :
$(textarea).val("some html like < input type='text' value='' style="background: url('http://www.w.com/bg.gif') repeat-x center;" /> bla bla");
or
$('#idTxtArGenHtml').val( $('idDivMain').html() );
I had problem with some special character ( & ' " )
when they are between quot. But when I use the function :
$(textarea).html()
the text is ok.
There an example form :
<FORM id="idFormContact" name="nFormContact" action="send.php" method="post" >
<FIELDSET id="idFieldContact" class="CMainFieldset">
<LEGEND>Test your newsletter» </LEGEND>
<p>Send to à : <input id='idInpMailList' type='text' value='[email protected]' /></p>
<FIELDSET class="CChildFieldset">
<LEGEND>Subject</LEGEND>
<LABEL for="idNomClient" class="CInfoLabel">Enter the subject: * </LABEL><BR/>
<INPUT value="" name="nSubject" type="text" id="idSubject" class="CFormInput" alt="Enter the Subject" ><BR/>
</FIELDSET>
<FIELDSET class="CChildFieldset">
<INPUT id="idBtnGen" type="button" value="Generate" onclick="onGenHtml();"/>
<INPUT id="idBtnSend" type="button" value="Send" onclick="onSend();"/><BR/><BR/>
<LEGEND>Message</LEGEND>
<LABEL for="idTxtArGenHtml" class="CInfoLabel">Html code : * </LABEL><BR/>
<span><TEXTAREA name="nTxtArGenHtml" id="idTxtArGenHtml" width='100%' cols="69" rows="300" alt="enter your message" ></TEXTAREA></span>
</FIELDSET>
</FIELDSET>
</FORM>
And javascript/jquery code that don't work to fill the textarea is :
function onGenHtml(){
$('#idTxtArGenHtml').html( $("#idDivMain").html() );
}
Finaly the solution :
function onGenHtml(){
$('#idTxtArGenHtml').html( $("#idDivMain").html() );
$('#idTxtArGenHtml').parent().replaceWith( '<span>'+$('#idTxtArGenHtml').parent().html()+'</span>');
}
The trick is wrap your textarea with a span tag to help with the replaceWith function. I'm not sure if it's very clean, but it's work perfect too add raw html code in a textarea.
var newElementsAppended = $(newHtml).appendTo("#myDiv");
newElementsAppended.effects("highlight", {}, 2000);
The already existing answers seem to only concern oneself with the *.java files themselves and not how to easily do it with library files that might be needed for the build.
A nice one-line situation which recursively gets all *.java files as well as includes *.jar files necessary for building is:
javac -cp ".:lib/*" -d bin $(find ./src/* | grep .java)
Here the bin file is the destination of class files, lib (and potentially the current working directory) contain the library files and all the java files in the src directory and beneath are compiled.
Use continue
instead of break

Yes, SqlBulkUpdate
is indeed the fastest tool for this type of task. I wanted to find "least effort" generic way for me in .NET Core so I ended up using great library from Marc Gravell called FastMember and writing one tiny extension method for entity framework DB context. Works lightning fast:
using System.Collections.Generic;
using System.Linq;
using FastMember;
using Microsoft.Data.SqlClient;
using Microsoft.EntityFrameworkCore;
namespace Services.Extensions
{
public static class DbContextExtensions
{
public static void BulkCopyToServer<T>(this DbContext db, IEnumerable<T> collection)
{
var messageEntityType = db.Model.FindEntityType(typeof(T));
var tableName = messageEntityType.GetSchema() + "." + messageEntityType.GetTableName();
var tableColumnMappings = messageEntityType.GetProperties()
.ToDictionary(p => p.PropertyInfo.Name, p => p.GetColumnName());
using (var connection = new SqlConnection(db.Database.GetDbConnection().ConnectionString))
using (var bulkCopy = new SqlBulkCopy(connection))
{
foreach (var (field, column) in tableColumnMappings)
{
bulkCopy.ColumnMappings.Add(field, column);
}
using (var reader = ObjectReader.Create(collection, tableColumnMappings.Keys.ToArray()))
{
bulkCopy.DestinationTableName = tableName;
connection.Open();
bulkCopy.WriteToServer(reader);
connection.Close();
}
}
}
}
}
You need to define the size of file...
header('Content-Length: ' . filesize($file));
And this line is wrong:
header("Content-Disposition:inline;filename='$filename");
You messed up quotas.
As a newbie in React world, I came across a similar issues where I could not edit
the textarea and struggled
with binding. It's worth knowing about controlled
and uncontrolled
elements when it comes to react.
The value of the following uncontrolled textarea
cannot be changed because of value
<textarea type="text" value="some value"
onChange={(event) => this.handleOnChange(event)}></textarea>
The value of the following uncontrolled textarea
can be changed because of use of defaultValue
or no value attribute
<textarea type="text" defaultValue="sample"
onChange={(event) => this.handleOnChange(event)}></textarea>
<textarea type="text"
onChange={(event) => this.handleOnChange(event)}></textarea>
The value of the following controlled textarea
can be changed because of how
value is mapped to a state as well as the onChange
event listener
<textarea value={this.state.textareaValue}
onChange={(event) => this.handleOnChange(event)}></textarea>
Here is my solution using different syntax. I prefer the auto-bind
than manual binding however, if I were to not use {(event) => this.onXXXX(event)}
then that would cause the content of textarea
to be not editable OR the event.preventDefault()
does not work as expected. Still a lot to learn I suppose.
class Editor extends React.Component {
constructor(props) {
super(props)
this.state = {
textareaValue: ''
}
}
handleOnChange(event) {
this.setState({
textareaValue: event.target.value
})
}
handleOnSubmit(event) {
event.preventDefault();
this.setState({
textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
})
}
render() {
return <div>
<form onSubmit={(event) => this.handleOnSubmit(event)}>
<textarea rows={10} cols={30} value={this.state.textareaValue}
onChange={(event) => this.handleOnChange(event)}></textarea>
<br/>
<input type="submit" value="Save"/>
</form>
</div>
}
}
ReactDOM.render(<Editor />, document.getElementById("content"));

If you may want to convert plaintext (not just numbers) to a BigInteger you will run into an exception, if you just try to: new BigInteger("not a Number")
In this case you could do it like this way:
public BigInteger stringToBigInteger(String string){
byte[] asciiCharacters = string.getBytes(StandardCharsets.US_ASCII);
StringBuilder asciiString = new StringBuilder();
for(byte asciiCharacter:asciiCharacters){
asciiString.append(Byte.toString(asciiCharacter));
}
BigInteger bigInteger = new BigInteger(asciiString.toString());
return bigInteger;
}

Some truly mobile detection is kind of hard programming and rather difficult. Eventually see the: http://detectmobilebrowsers.com/ or other similar sources.
Try doing like this: array1.compare(array2)=true
Array.prototype.compare = function (array) {
// if the other array is a falsy value, return
if (!array)
return false;
// compare lengths - can save a lot of time
if (this.length != array.length)
return false;
for (var i = 0, l=this.length; i < l; i++) {
// Check if we have nested arrays
if (this[i] instanceof Array && array[i] instanceof Array) {
// recurse into the nested arrays
if (!this[i].compare(array[i]))
return false;
}
else if (this[i] != array[i]) {
// Warning - two different object instances will never be equal: {x:20} != {x:20}
return false;
}
}
return true;
}
Base URL should be absolute, including the protocol:
$config['base_url'] = "http://".$_SERVER['SERVER_NAME']."/mysite/";
This configuration will work in both localhost and server.
Don't forget to enable on autoload:
$autoload['helper'] = array('url','file');
Then base_url() will output as below
echo base_url('assets/style.css'); //http://yoursite.com/mysite/assets/style.css
Note the output while doing the merge - it is saying Fast Forward
In such situations, you want to do:
git merge v1.0 --no-commit --no-ff
One option is to use do.call()
:

Maybe this will help others in the future - I had the same error while trying to multiple a float and a list of floats. The thing is that everyone here talked about multiplying a float with a string (but here all my element were floats all along) so the problem was actually using the * operator on a list.
For example:
import math
import numpy as np
alpha = 0.2
beta=1-alpha
C = (-math.log(1-beta))/alpha
coff = [0.0,0.01,0.0,0.35,0.98,0.001,0.0]
coff *= C
The error:
coff *= C
TypeError: can't multiply sequence by non-int of type 'float'
The solution - convert the list to numpy array:
coff = np.asarray(coff) * C
There is no difference between moving and renaming; you should simply call Directory.Move
.
In general, if you're only doing a single operation, you should use the static
methods in the File
and Directory
classes instead of creating FileInfo
and DirectoryInfo
objects.
For more advice when working with files and directories, see here.
So long as Excel can open the file, the functionality to change the format of the opened file is built in.
To convert an .html file, open it using Excel (File - Open) and then save it as a .xlsx file from Excel (File - Save as).
To do it using VBA, the code would look like this:
Sub Open_HTML_Save_XLSX()
Workbooks.Open Filename:="C:\Temp\Example.html"
ActiveWorkbook.SaveAs Filename:= _
"C:\Temp\Example.xlsx", FileFormat:= _
xlOpenXMLWorkbook
End Sub
This should work nicely:
UPDATE tb_Company SET CompanyIndustry =
CONCAT(UPPER(LEFT(CompanyIndustry, 1)), SUBSTRING(CompanyIndustry, 2))
Try this...
<div class="row">
<div class="col-xs-3">
Menu
</div>
<div class="col-xs-9">
<div class="row">
<div class="col-sm-4 col-sm-push-8">
Right content
</div>
<div class="col-sm-8 col-sm-pull-4">
Content
</div>
</div>
</div>
</div>
//Html Format of the dropdown list.
<select id="MyDropDownList">
<option value=test1 selected>test1</option>
<option value=test2>test2</option>
<option value=test3>test3</option>
<option value=test4>test4</option>
// If you want to change the selected Item to test2 using javascript. Try this one. // set the next option u want to select
var NewOprionValue = "Test2"
var RemoveSelected = $("#MyDropDownList")[0].innerHTML.replace('selected', '');
var ChangeSelected = RemoveSelected.replace(NewOption, NewOption + 'selected>');
$('#MyDropDownList').html(ChangeSelected);
You can use focus event of button. This worked in case of angular
<button (focus)=false >Click</button
This would truncate the file:
$fh = fopen( 'filelist.txt', 'w' );
fclose($fh);
In clear.php, redirect to the caller page by making use of $_SERVER['HTTP_REFERER']
value.
There is no need to install virtualenv. Just create a workfolder and open your editor in it. Assuming you are using vscode,
$mkdir Directory && cd Directory
$code .
It is the best way to avoid breaking Ubuntu/linux dependencies by messing around with environments. In case anything goes wrong, you can always delete that folder and begin afresh. Otherwise, messing up with the ubuntu/linux python environments could mess up system apps/OS (including the terminal). Then you can press shift+P and type python:select interpreter. Choose any version above 3. After that you can do
$pip3 -v
It will display the pip version. You can then use it for installations as
$pip3 install Library
According to Javascript Date Documentation, you can easily do this way:
var twoHoursBefore = new Date();
twoHoursBefore.setHours(twoHoursBefore.getHours() - 2);
And don't worry about if hours you set will be out of 0..23
range.
Date() object will update the date accordingly.
Check if password you are using is correct one by running below command
keytool -keypasswd -new temp123 -keystore awsdemo-keystore.jks -storepass temp123 -alias movie-service -keypass changeit
If you are getting below error then your password is wrong
keytool error: java.security.UnrecoverableKeyException: Cannot recover key
You can just do it like this:
#content {
position: relative;
}
#content img {
position: absolute;
top: 0px;
right: 0px;
}
<div id="content">
<img src="images/ribbon.png" class="ribbon"/>
<div>some text...</div>
</div>
You need to create a copy of the list before you modify its contents. A quick shortcut to duplicate a list is this:
mylist[:]
Example:
>>> first = [1,2,3]
>>> second = first[:]
>>> second.append(4)
>>> first
[1, 2, 3]
>>> second
[1, 2, 3, 4]
And to show the default behavior that would modify the orignal list (since a name in Python is just a reference to the underlying object):
>>> first = [1,2,3]
>>> second = first
>>> second.append(4)
>>> first
[1, 2, 3, 4]
>>> second
[1, 2, 3, 4]
Note that this only works for lists. If you need to duplicate the contents of a dictionary, you must use copy.deepcopy()
as suggested by others.
What you are looking for is a query with WITH
clause, if your dbms supports it. Then
WITH NewScores AS (
SELECT *
FROM Score
WHERE InsertedDate >= DATEADD(mm, -3, GETDATE())
)
SELECT
<and the rest of your query>
;
Note that there is no ;
in the first half. HTH.
It doesn't work because Date - Date
relies on exactly the kind of type coercion TypeScript is designed to prevent.
There is a workaround this using the +
prefix:
var t = Date.now() - +(new Date("2013-02-20T12:01:04.753Z");
Or, if you prefer not to use Date.now()
:
var t = +(new Date()) - +(new Date("2013-02-20T12:01:04.753Z"));
Or see Siddharth Singh's answer, below, for a more elegant solution using valueOf()
To select top n rows updated recently
SELECT *
FROM (
SELECT *
FROM table
ORDER BY UpdateDateTime DESC
)
WHERE ROWNUM < 101;
I was trying to do the exact same thing, open a text file (a CSV for Pandas actually). Don't want to make a copy of it, just want to open it. The form-WTF has a nice file browser, but then it opens the file and makes a temporary file, which it presents as a memory stream. With a little work under the hood,
form = UploadForm()
if form.validate_on_submit():
filename = secure_filename(form.fileContents.data.filename)
filestream = form.fileContents.data
filestream.seek(0)
ef = pd.read_csv( filestream )
sr = pd.DataFrame(ef)
return render_template('dataframe.html',tables=[sr.to_html(justify='center, classes='table table-bordered table-hover')],titles = [filename], form=form)
XmlSerializer sr = new XmlSerializer(objectToSerialize.GetType());
TextWriter xmlWriter = new StreamWriter(filename);
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add(string.Empty, string.Empty);
sr.Serialize(xmlWriter, objectToSerialize, namespaces);
You can call tesseract API function from C code:
#include <tesseract/baseapi.h>
#include <tesseract/ocrclass.h>; // ETEXT_DESC
using namespace tesseract;
class TessAPI : public TessBaseAPI {
public:
void PrintRects(int len);
};
...
TessAPI *api = new TessAPI();
int res = api->Init(NULL, "rus");
api->SetAccuracyVSpeed(AVS_MOST_ACCURATE);
api->SetImage(data, w0, h0, bpp, stride);
api->SetRectangle(x0,y0,w0,h0);
char *text;
ETEXT_DESC monitor;
api->RecognizeForChopTest(&monitor);
text = api->GetUTF8Text();
printf("text: %s\n", text);
printf("m.count: %s\n", monitor.count);
printf("m.progress: %s\n", monitor.progress);
api->RecognizeForChopTest(&monitor);
text = api->GetUTF8Text();
printf("text: %s\n", text);
...
api->End();
And build this code:
g++ -g -I. -I/usr/local/include -o _test test.cpp -ltesseract_api -lfreeimageplus
(i need FreeImage for picture loading)
1.-In XAMPP press button Shell
2.-place command:
mysqladmin -u root password
New password: aqui colocar password ejemplo ´09876´
3.-go on the local disk c: xampp \ phpMyAdmin open config.inic.php with notepad ++
5.- add the password and in AllowNoPassword change to false
/* Authentication type and info */
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '09876';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = false;
$cfg['Lang'] = '';
6.- save changes, clear browser cache and restart xampp
There is no unmarshal(String)
method. You should use a Reader
:
Person person = (Person) unmarshaller.unmarshal(new StringReader("xml string"));
But usually you are getting that string from somewhere, for example a file. If that's the case, better pass the FileReader
itself.
Hi the problem is in FileDownloader class
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
You need to remove the above two lines and everything will work fine. Please mark the question as answered if it is working as expected.

There are no buts about it! Who want to grasp the subject must do the following ones,
- Peruse The Lost Art of Structure Packing written by Eric S. Raymond
- Glance at Eric's code example
- Last but not least, don't forget the following rule about padding that a struct is aligned to the largest type’s alignment requirements.
Generally, Threads are called light weight process. If we divide memory into three sections then it will be: Code, data and Stack. Every process has its own code, data and stack sections and due to this context switch time is a little high. To reduce context switching time, people have come up with concept of thread, which shares Data and code segment with other thread/process and it has its own STACK segment.

The standard function atoi()
will likely do what you want.

int main(int argc, char *argv[])
{
int useconds = atoi(argv[1]);
usleep(useconds);
}
If you are unaware of the position to replace, use list iterator to find and replace element ListIterator.set(E e)
ListIterator<String> iterator = list.listIterator();
while (iterator.hasNext()) {
String next = iterator.next();
if (next.equals("Two")) {
//Replace element
iterator.set("New");
}
}
In newer version of git (2.23+) you can use:

You can change your PrintWriter and use method getAbsoluteFile(), this function returns the absolute File object of the given abstract pathname.
PrintWriter out = new PrintWriter(new FileWriter(log.getAbsoluteFile(), true));
I understand this question is for sql server 2012, but if the same scenario for SQL Server 2017 or SQL Azure you can use Trim

I am late but there are a handful of easy ways to do this as mentioned:
$days = date("t");
$days = cal_days_in_month(CAL_GREGORIAN, date('m'), date('Y'));
$days = date("j",mktime (date("H"),date("i"),date("s"),(date("n")+1),0,date("Y")));
Using mktime() is my go to for complete control over all aspects of time... I.E.
echo "<br> ".date("Y-n-j",mktime (date("H"),date("i"),date("s"),(11+1),0,2009));
Setting the day to 0 and moving your month up 1 will give you the last day of the previous month. 0 and negative numbers have the similar affect in the different arguements. PHP: mktime - Manual
As a few have said strtotime isn't the most solid way to go and little if none are as easily versatile.

$("#myDiv").hide();
will set the css display to none. if you need to set visibility to hidden as well, could do this via
$("#myDiv").css("visibility", "hidden");
or combine both in a chain
$("#myDiv").hide().css("visibility", "hidden");
or write everything with one css() function
$("#myDiv").css({
display: "none",
visibility: "hidden"
});

There's a far more simpler solution to tackle this.
The reason why you get ValueError: Index contains duplicate entries, cannot reshape
is because, once you unstack "Location
", then the remaining index columns "id
" and "date
" combinations are no longer unique.
You can avoid this by retaining the default index column (row #) and while setting the index using "id
", "date
" and "location
", add it in "append
" mode instead of the default overwrite mode.
So use,
e.set_index(['id', 'date', 'location'], append=True)
Once this is done, your index columns will still have the default index along with the set indexes. And unstack
will work.
Let me know how it works out.
You can use bootstrap flex class name like that:
<div class="d-flex justify-content-center">

The difference between a variable, field, attribute, and property in Java:
A variable is the name given to a memory location. It is the basic unit of storage in a program.
A field is a data member of a class. Unless specified otherwise, a field can be public, static, not static and final.
An attribute is another term for a field. It’s typically a public field that can be accessed directly.
A property is a term used for fields, but it typically has getter and setter combination.

Whatever is specified in the command
in docker-compose.yml should get appended to the entrypoint
defined in the Dockerfile, provided entrypoint
is defined in exec form in the Dockerfile.
If the EntryPoint is defined in shell form, then any CMD arguments will be ignored.
I had got the same CORS error while working on a Vue.js project. You can resolve this either by building a proxy server or another way would be to disable the security settings of your browser (eg, CHROME) for accessing cross origin apis (this is temporary solution & not the best way to solve the issue). Both these solutions had worked for me. The later solution does not require any mock server or a proxy server to be build. Both these solutions can be resolved at the front end.
You can disable the chrome security settings for accessing apis out of the origin by typing the below command on the terminal:
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --user-data-dir="/tmp/chrome_dev_session" --disable-web-security
After running the above command on your terminal, a new chrome window with security settings disabled will open up. Now, run your program (npm run serve / npm run dev) again and this time you will not get any CORS error and would be able to GET request using axios.
Hope this helps!
Given an object which I suspect to be some kind of IList<>
, how can I determine of what it's an IList<>
?
Here's a reliable solution. My apologies for length - C#'s introspection API makes this suprisingly difficult.
/// <summary>
/// Test if a type implements IList of T, and if so, determine T.
/// </summary>
public static bool TryListOfWhat(Type type, out Type innerType)
{
Contract.Requires(type != null);
var interfaceTest = new Func<Type, Type>(i => i.IsGenericType && i.GetGenericTypeDefinition() == typeof(IList<>) ? i.GetGenericArguments().Single() : null);
innerType = interfaceTest(type);
if (innerType != null)
{
return true;
}
foreach (var i in type.GetInterfaces())
{
innerType = interfaceTest(i);
if (innerType != null)
{
return true;
}
}
return false;
}
Example usage:
object value = new ObservableCollection<int>();
Type innerType;
TryListOfWhat(value.GetType(), out innerType).Dump();
innerType.Dump();
Returns
True
typeof(Int32)
Join-Path is not exactly what you are looking for. It has multiple uses but not the one you are looking for. An example from Partying with Join-Path:
Join-Path C:\hello,d:\goodbye,e:\hola,f:\adios world
C:\hello\world
d:\goodbye\world
e:\hola\world
f:\adios\world
You see that it accepts an array of strings, and it concatenates the child string to each creating full paths. In your example, $path = join-path C: "Program Files" "Microsoft Office"
. You are getting the error since you are passing three positional arguments and join-path
only accepts two. What you are looking for is a -join
, and I could see this being a misunderstanding. Consider instead this with your example:
"C:","Program Files","Microsoft Office" -join "\"
-Join
takes the array of items and concatenates them with \
into a single string.
C:\Program Files\Microsoft Office
Minor attempt at a salvage
Yes, I will agree that this answer is better, but mine could still work. Comments suggest there could be an issue with slashes, so to keep with my concatenation approach you could do this as well.
"C:","\\Program Files\","Microsoft Office\" -join "\" -replace "(?!^\\)\\{2,}","\"
So if there are issues with extra slashes it could be handled as long as they are not in the beginning of the string (allows UNC paths). [io.path]::combine('c:\', 'foo', '\bar\')
would not work as expected and mine would account for that. Both require proper strings for input as you cannot account for all scenarios. Consider both approaches, but, yes, the other higher-rated answer is more terse, and I didn't even know it existed.
Also, would like to point out, my answer explains how what the OP doing was wrong on top of providing a suggestion to address the core problem.
