The process for timing out an operations is described in the documentation for signal.
The basic idea is to use signal handlers to set an alarm for some time interval and raise an exception once that timer expires.
Note that this will only work on UNIX.
Here's an implementation that creates a decorator (save the following code as timeout.py
).
from functools import wraps
import errno
import os
import signal
class TimeoutError(Exception):
pass
def timeout(seconds=10, error_message=os.strerror(errno.ETIME)):
def decorator(func):
def _handle_timeout(signum, frame):
raise TimeoutError(error_message)
def wrapper(*args, **kwargs):
signal.signal(signal.SIGALRM, _handle_timeout)
signal.alarm(seconds)
try:
result = func(*args, **kwargs)
finally:
signal.alarm(0)
return result
return wraps(func)(wrapper)
return decorator
This creates a decorator called @timeout
that can be applied to any long running functions.
So, in your application code, you can use the decorator like so:
from timeout import timeout
# Timeout a long running function with the default expiry of 10 seconds.
@timeout
def long_running_function1():
...
# Timeout after 5 seconds
@timeout(5)
def long_running_function2():
...
# Timeout after 30 seconds, with the error "Connection timed out"
@timeout(30, os.strerror(errno.ETIMEDOUT))
def long_running_function3():
...
For MacOS this worked for me without the need to hardcode a particular Java version:
launchctl setenv JAVA_HOME "$(jenv javahome)"
set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%
The single quotes do not indicate a string, they make it starts: 'C:\
instead of C:\
so
%name%
is the usual syntax for expanding a variable, the !name!
syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION
first, or by running the command prompt with CMD /V:ON
.
Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4
to keep the current PATH content, and add something to the end.
You can try as below :
declare @list varchar(MAX), @i int
select @i=0, @list ='4,7,12,22,19,'
while( @i < LEN(@list))
begin
declare @item varchar(MAX)
SELECT @item = SUBSTRING(@list, @i,CHARINDEX(',',@list,@i)-@i)
select @item
--do your stuff here with @item
exec p_MyInnerProcedure @item
set @i = CHARINDEX(',',@list,@i)+1
if(@i = 0) set @i = LEN(@list)
end
You have to take whole columns under resizebox. This code worked for me
\begin{table}[htbp]
\caption{Sample Table.}\label{tab1}
\resizebox{\columnwidth}{!}{\begin{tabular}{|l|l|l|l|l|}
\hline
URL & First Time Visit & Last Time Visit & URL Counts & Value\\
\hline
https://web.facebook.com/ & 1521241972 & 1522351859 & 177 & 56640\\
http://localhost/phpmyadmin/ & 1518413861 & 1522075694 & 24 & 39312\\

\end{tabular}}
\end{table}
This snippet works fine, for sending the Bearer Token using Jersey Client.
WebTarget webTarget = client.target("endpoint");
Invocation.Builder invocationBuilder = webTarget.request(MediaType.APPLICATION_JSON);
invocationBuilder.header("Authorization", "Bearer "+"Api Key");
Response response = invocationBuilder.get();
String responseData = response.readEntity(String.class);
System.out.println(response.getStatus());
System.out.println("responseData "+responseData);
Use this code:
import java.nio.file.Files;
import java.nio.file.Paths;
public class FileWork
{
public static void main(String[] args) throws IOException {
String line = Files.readAllLines(Paths.get("D:/abc.txt")).get(1);
System.out.println(line);
}
}
I don't think there is anything you can do to avoid what you are already doing, however, if you are building the table on the client with javascript, you can always add the style rules dynamically, so you can allow for any number of columns without cluttering up your css file with all those rules. See http://www.hunlock.com/blogs/Totally_Pwn_CSS_with_Javascript if you don't know how to do this.
Edit: For your "sticky" toggle, you should just append class names rather than replacing them. For instance, you can give it a class name of "hide2 hide3" etc. I don't think you really need the "show" classes, since that would be the default. Libraries like jQuery make this easy, but in the absence, a function like this might help:
var modifyClassName = function (elem, add, string) {
var s = (elem.className) ? elem.className : "";
var a = s.split(" ");
if (add) {
for (var i=0; i<a.length; i++) {
if (a[i] == string) {
return;
}
}
s += " " + string;
}
else {
s = "";
for (var i=0; i<a.length; i++) {
if (a[i] != string)
s += a[i] + " ";
}
}
elem.className = s;
}
var index = ctx.Items.FirstOrDefault(item => Equals(item.Value, Settings.Default.Format_Encoding));
ctx.SelectedIndex = ctx.Items.IndexOf(index);
OR
foreach (var listItem in ctx.Items)
listItem.Selected = Equals(listItem.Value as Encoding, Settings.Default.Format_Encoding);
Should work.. especially when using extended RAD controls in which FindByText/Value doesn't even exist!
The only thing that worked for me:
Target > Build Phases > [CP] Embed Pods Frameworks Uncheck "Show environment variables in build log" and "Run script only when installing"
Why not check HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\[office.exe]
, where [office.exe]
stands for particular office product exe-filename, e.g. winword.exe
, excel.exe
etc.
There you get path to executable and check version of that file.
How to check version of the file: in C++ / in C#
Any criticism towards such approach?
I have adapted the script from Russ Cam (thank you, Russ Cam!) to my own needs: I needed to merge any columns that had the same value, not just empty cells.
This could be useful to someone else... Here is what I have come up with:
jQuery(document).ready(function() {
jQuery('table.tblSimpleAgenda tr').each(function() {
var tr = this;
var counter = 0;
var strLookupText = '';
jQuery('td', tr).each(function(index, value) {
var td = jQuery(this);
if ((td.text() == strLookupText) || (td.text() == "")) {
counter++;
td.prev().attr('colSpan', '' + parseInt(counter + 1,10) + '').css({textAlign : 'center'});
td.remove();
}
else {
counter = 0;
}
// Sets the strLookupText variable to hold the current value. The next time in the loop the system will check the current value against the previous value.
strLookupText = td.text();
});
});
});
I found that using the http://pencil.evolus.vn/ together with the pencil-stencils from the http://code.google.com/p/android-ui-utils/ project works exceptionally well. Very simple to use, its very easy to mock up elaborate designs
Use a format string to round up to two decimal places and convert the double
to a String
:
let currentRatio = Double (rxCurrentTextField.text!)! / Double (txCurrentTextField.text!)!
railRatioLabelField.text! = String(format: "%.2f", currentRatio)
Example:
let myDouble = 3.141
let doubleStr = String(format: "%.2f", myDouble) // "3.14"
If you want to round up your last decimal place, you could do something like this (thanks Phoen1xUK):
let myDouble = 3.141
let doubleStr = String(format: "%.2f", ceil(myDouble*100)/100) // "3.15"
From your Activity
, just pass in this
as the Context
for your layout:
ProfileView pv = new ProfileView(this, null, temp, tempPd);
Afterwards you will have a Context
in the layout, but you will know it is actually your Activity
and you can cast it so that you have what you need:
Activity activity = (Activity) context;
Your code looks fine except the possibility that if the variable declaration is inside a dom read handler then it will not be a global variable... it will be a closure variable
jQuery(function(){
//here it is a closure variable
var a_href;
$('sth a').on('click', function(e){
a_href = $(this).attr('href');
console.log(a_href);
//output is "home"
e.preventDefault();
}
})
To make the variable global, one solution is to declare the variable in global scope
var a_href;
jQuery(function(){
$('sth a').on('click', function(e){
a_href = $(this).attr('href');
console.log(a_href);
//output is "home"
e.preventDefault();
}
})
another is to set the variable as a property of the window object
window.a_href = $(this).attr('href')
Why console printing undefined
You are getting the output as undefined
because even though the variable is declared, you have not initialized it with a value, the value of the variable is set only after the a
element is clicked till that time the variable will have the value undefined
. If you are not declaring the variable it will throw a ReferenceError
I have struggled with the matplotlib trimming methods, so I've now just made a function to do this via a bash
call to ImageMagick
's mogrify command, which works well and gets all extra white space off the figure's edge. This requires that you are using UNIX/Linux, are using the bash
shell, and have ImageMagick
installed.
Just throw a call to this after your savefig()
call.
def autocrop_img(filename):
'''Call ImageMagick mogrify from bash to autocrop image'''
import subprocess
import os
cwd, img_name = os.path.split(filename)
bashcmd = 'mogrify -trim %s' % img_name
process = subprocess.Popen(bashcmd.split(), stdout=subprocess.PIPE, cwd=cwd)
Solution in Kotlin (will work in Java too, of course), which includes both cases of when you know the size or not:
fun InputStream.readBytesWithSize(size: Long): ByteArray? {
return when {
size < 0L -> this.readBytes()
size == 0L -> ByteArray(0)
size > Int.MAX_VALUE -> null
else -> {
val sizeInt = size.toInt()
val result = ByteArray(sizeInt)
readBytesIntoByteArray(result, sizeInt)
result
}
}
}
fun InputStream.readBytesIntoByteArray(byteArray: ByteArray,bytesToRead:Int=byteArray.size) {
var offset = 0
while (true) {
val read = this.read(byteArray, offset, bytesToRead - offset)
if (read == -1)
break
offset += read
if (offset >= bytesToRead)
break
}
}
If you know the size, it saves you on having double the memory used compared to the other solutions (in a brief moment, but still could be useful). That's because you have to read the entire stream to the end, and then convert it to a byte array (similar to ArrayList which you convert to just an array).
So, if you are on Android, for example, and you got some Uri to handle, you can try to get the size using this:
fun getStreamLengthFromUri(context: Context, uri: Uri): Long {
context.contentResolver.query(uri, arrayOf(MediaStore.MediaColumns.SIZE), null, null, null)?.use {
if (!it.moveToNext())
return@use
val fileSize = it.getLong(it.getColumnIndex(MediaStore.MediaColumns.SIZE))
if (fileSize > 0)
return fileSize
}
//if you wish, you can also get the file-path from the uri here, and then try to get its size, using this: https://stackoverflow.com/a/61835665/878126
FileUtilEx.getFilePathFromUri(context, uri, false)?.use {
val file = it.file
val fileSize = file.length()
if (fileSize > 0)
return fileSize
}
context.contentResolver.openInputStream(uri)?.use { inputStream ->
if (inputStream is FileInputStream)
return inputStream.channel.size()
else {
var bytesCount = 0L
while (true) {
val available = inputStream.available()
if (available == 0)
break
val skip = inputStream.skip(available.toLong())
if (skip < 0)
break
bytesCount += skip
}
if (bytesCount > 0L)
return bytesCount
}
}
return -1L
}
You can use Formic with Python 2.6
import formic
fileset = formic.FileSet(include="**/*.txt", directory="C:/Users/sam/Desktop/")
Disclosure - I am the author of this package.
I tried following the above tutorial. Thing is tensorflow changes a lot and so do the NVIDIA versions needed for running on a GPU. The next issue is that your driver version determines your toolkit version etc. As of today this information about the software requirements should shed some light on how they interplay:
NVIDIA® GPU drivers —CUDA 9.0 requires 384.x or higher.
CUDA® Toolkit —TensorFlow supports CUDA 9.0.
CUPTI ships with the CUDA Toolkit.
cuDNN SDK (>= 7.2) Note: Make sure your GPU has compute compatibility >3.0
(Optional) NCCL 2.2 for multiple GPU support.
(Optional) TensorRT 4.0 to improve latency and throughput for inference on some models.
And here you'll find the up-to-date requirements stated by tensorflow (which will hopefully be updated by them on a regular basis).
Set the containing element/div to a height. Otherwise your asking the browser to set the height to 100% of an unknown value and it can't.

I agree with @ZombieSheep. Just one more thing - I generally don't think that databases actually need be portable because you miss all the features your DBMS vendor provides. I think that migrating to another database would be the last thing one would consider. Just my $.02
Usign fs with node.

and usage:
puts "I'm back green".bg_green
puts "I'm red and back cyan".red.bg_cyan
puts "I'm bold and green and backround red".bold.green.bg_red
on my console:
def no_colors
self.gsub /\e\[\d+m/, ""
end
removes formatting characters
puts "\e[31m" # set format (red foreground)
puts "\e[0m" # clear format
puts "green-#{"red".red}-green".green # will be green-red-normal, because of \e[0
The default behaviour for error_log() is to output to the Apache error log. If this isn't happening check your php.ini settings for the error_log directive. Leave it unset to use the Apache log file for the current vhost.
In IE9, it is possible with purely a hack as advised by @Spudley. Since you've customized height and width of the div and select, you need to change div:before
css to match yours.
In case if it is IE10 then using below css3 it is possible
select::-ms-expand {
display: none;
}
However if you're interested in jQuery plugin, try Chosen.js
or you can create your own in js.
As other posters have said, you need to change the LayoutManager being used. I always preferred using a GridLayout so your code would become:
MainPanel mainPanel = new MainPanel();
JFrame mainFrame = new JFrame();
mainFrame.setLayout(new GridLayout());
mainFrame.pack();
mainFrame.setVisible(true);
GridLayout seems more conceptually correct to me when you want your panel to take up the entire screen.
Here is a very good solution -> http://css-tricks.com/replace-the-image-in-an-img-with-css/
Pro(s) and Con(s):
(+) works with vector image that have relative width/height (a thing that RobAu's answer does not handle)
(+) is cross browser (works also for IE8+)
(+) it only uses CSS. So no need to modify the img src (or if you do not have access/do not want to change the already existing img src attribute).
(-) sorry, it does use the background css attribute :)
Use the id selector #
$('#passwordsNoMatchRegister').show();
If you plan on getting a random value a lot, you might want to define a function for it.
First, put this in your code somewhere:
Array.prototype.sample = function(){
return this[Math.floor(Math.random()*this.length)];
}
Now:
[1,2,3,4].sample() //=> a random element

Composition means creating an object to a class which has relation with that particular class. Suppose Student has relation with Accounts;
An Inheritance is, this is the previous class with the extended feature. That means this new class is the Old class with some extended feature. Suppose Student is Student but All Students are Human. So there is a relationship with student and human. This is Inheritance.
It's quite simple actually if you're using PostgreSQL, just use distinct(columns)
(documentation).
Productorder.objects.all().distinct('category')
Note that this feature has been included in Django since 1.4
You will be much happier using a dictionary instead:
my_data = {}
foo = "hello"
my_data[foo] = "goodbye"
assert my_data["hello"] == "goodbye"
1) Go to conf
folder in tomcat installation directory
e.g. C:\Tomcat 6.0\conf\
2) Edit following tag in server.xml
file
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
3) Change the port=8080
value to port=80
4) Save file.
5) Stop your Tomcat and restart it.
I use this for every external link:
window.onload = function(){
var anchors = document.getElementsByTagName('a');
for (var i=0; i<anchors.length; i++){
if (anchors[i].hostname != window.location.hostname) {
anchors[i].setAttribute('target', '_blank');
}
}
}
times = function () {
var length = arguments.length;
for (var i = 0; i < length ; i++) {
for (var j = 0; j < arguments[i]; j++) {
dosomthing();
}
}
}
You can call it like this:
times(3,4);
times(1,2,3,4);
times(1,3,5,7,9);
the equivalent to the batch program would be
#include<iostream>
int main()
{
std::cout<<"Hello, World!\n";
std::cin.get();
return 0;
}
The additional line does exactly what PAUSE
does, waits for a single character input
This is an intuitive solution using the viewport command that just sets the minimum height to the viewport height minus the footer height.
html,body{
height: 100%
}
#nonFooter{
min-height: calc(100vh - 30px)
}
#footer {
height:30px;
margin: 0;
clear: both;
width:100%;
}

The below answer is no more relevant to present day.
So for any one looking for answers you should look at the documentation linked below
https://developer.android.com/training/articles/user-data-ids
Old Answer - Not relevant now. You check this blog in the link below
http://android-developers.blogspot.in/2011/03/identifying-app-installations.html
ANDROID_ID
import android.provider.Settings.Secure;
private String android_id = Secure.getString(getContext().getContentResolver(),
Secure.ANDROID_ID);
The above is from the link @ Is there a unique Android device ID?
More specifically, Settings.Secure.ANDROID_ID. This is a 64-bit quantity that is generated and stored when the device first boots. It is reset when the device is wiped.
ANDROID_ID seems a good choice for a unique device identifier. There are downsides: First, it is not 100% reliable on releases of Android prior to 2.2 (“Froyo”). Also, there has been at least one widely-observed bug in a popular handset from a major manufacturer, where every instance has the same ANDROID_ID.
The below solution is not a good one coz the value survives device wipes (“Factory resets”) and thus you could end up making a nasty mistake when one of your customers wipes their device and passes it on to another person.
You get the imei number of the device using the below
TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.getDeviceId();

Assuming you’ve literally got two date objects, you can subtract one from the other and query the resulting timedelta
object for the number of days:
>>> from datetime import date
>>> a = date(2011,11,24)
>>> b = date(2011,11,17)
>>> a-b
datetime.timedelta(7)
>>> (a-b).days
7
And it works with datetimes too — I think it rounds down to the nearest day:
>>> from datetime import datetime
>>> a = datetime(2011,11,24,0,0,0)
>>> b = datetime(2011,11,17,23,59,59)
>>> a-b
datetime.timedelta(6, 1)
>>> (a-b).days
6
Just make a comparison function/functor:
bool my_cmp(const data& a, const data& b)
{
// smallest comes first
return a.word.size() < b.word.size();
}
std::sort(info.begin(), info.end(), my_cmp);
Or provide an bool operator<(const data& a) const
in your data
class:
struct data {
string word;
int number;
bool operator<(const data& a) const
{
return word.size() < a.word.size();
}
};
or non-member as Fred said:
struct data {
string word;
int number;
};
bool operator<(const data& a, const data& b)
{
return a.word.size() < b.word.size();
}
and just call std::sort()
:
std::sort(info.begin(), info.end());
I used Storm + SQLite for a small project, and was pretty happy with it until I added multiprocessing. Trying to use the database from multiple processes resulted in a "Database is locked" exception. I switched to SQLAlchemy, and the same code worked with no problems.
From Java 1.5 it's always a good Idea to consider java.util.concurrent package. They are the state of the art locking mechanism in java right now. The synchronize mechanism is more heavyweight that the java.util.concurrent classes.
The example would look something like this:
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;
public class Sample {
private final Lock lock = new ReentrantLock();
private String message = null;
public void newmsg(String msg) {
lock.lock();
try {
message = msg;
} finally {
lock.unlock();
}
}
public String getmsg() {
lock.lock();
try {
String temp = message;
message = null;
return temp;
} finally {
lock.unlock();
}
}
}
Another option (which is useful e.g. for scientific purposes when you need to work with segmentation masks) is simply apply a threshold:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""Binarize (make it black and white) an image with Python."""
from PIL import Image
from scipy.misc import imsave
import numpy
def binarize_image(img_path, target_path, threshold):
"""Binarize an image."""
image_file = Image.open(img_path)
image = image_file.convert('L') # convert image to monochrome
image = numpy.array(image)
image = binarize_array(image, threshold)
imsave(target_path, image)
def binarize_array(numpy_array, threshold=200):
"""Binarize a numpy array."""
for i in range(len(numpy_array)):
for j in range(len(numpy_array[0])):
if numpy_array[i][j] > threshold:
numpy_array[i][j] = 255
else:
numpy_array[i][j] = 0
return numpy_array
def get_parser():
"""Get parser object for script xy.py."""
from argparse import ArgumentParser, ArgumentDefaultsHelpFormatter
parser = ArgumentParser(description=__doc__,
formatter_class=ArgumentDefaultsHelpFormatter)
parser.add_argument("-i", "--input",
dest="input",
help="read this file",
metavar="FILE",
required=True)
parser.add_argument("-o", "--output",
dest="output",
help="write binarized file hre",
metavar="FILE",
required=True)
parser.add_argument("--threshold",
dest="threshold",
default=200,
type=int,
help="Threshold when to show white")
return parser
if __name__ == "__main__":
args = get_parser().parse_args()
binarize_image(args.input, args.output, args.threshold)
It looks like this for ./binarize.py -i convert_image.png -o result_bin.png --threshold 200
:
you can (sort of) return an array
instead of
int m1[5] = {1, 2, 3, 4, 5};
int m2[5] = {6, 7, 8, 9, 10};
int* m3 = test(m1, m2);
write
struct mystruct
{
int arr[5];
};
int m1[5] = {1, 2, 3, 4, 5};
int m2[5] = {6, 7, 8, 9, 10};
mystruct m3 = test(m1,m2);
where test looks like
struct mystruct test(int m1[5], int m2[5])
{
struct mystruct s;
for (int i = 0; i < 5; ++i ) s.arr[i]=m1[i]+m2[i];
return s;
}
not very efficient since one is copying it delivers a copy of the array
Use ProcessBuilder to separate commands and arguments instead of spaces. This should work regardless of shell used:
import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
public class Test {
public static void main(final String[] args) throws IOException, InterruptedException {
//Build command
List<String> commands = new ArrayList<String>();
commands.add("/bin/cat");
//Add arguments
commands.add("/home/narek/pk.txt");
System.out.println(commands);

attachedCompanyIDs is one big string, so mysql try to find company in this its cast to integer
when you use where in
so if comapnyid = 1 :
companyID IN ('1,2,3')
this is return true
but if the number 1 is not in the first place
companyID IN ('2,3,1')
its return false
SELECT TIMESTAMPDIFF(SECOND,'2018-01-19 14:17:15','2018-01-20 14:17:15');
Second approach
SELECT ( DATEDIFF('1993-02-20','1993-02-19')*( 24*60*60) )AS 'seccond';
CURRENT_TIME() --this will return current Date
DATEDIFF('','') --this function will return DAYS and in 1 day there are 24hh 60mm 60sec
$ git clone --mirror $URL
is a short-hand for
$ git clone --bare $URL
$ (cd $(basename $URL) && git remote add --mirror=fetch origin $URL)
(Copied directly from here)
How the current man-page puts it:
Compared to
--bare
,--mirror
not only maps local branches of the source to local branches of the target, it maps all refs (including remote branches, notes etc.) and sets up a refspec configuration such that all these refs are overwritten by agit remote update
in the target repository.
std::map::find
returns an iterator to the found element (or to the end()
if the element was not found). So long as the map
is not const, you can modify the element pointed to by the iterator:
std::map<char, int> m;
m.insert(std::make_pair('c', 0)); // c is for cookie
std::map<char, int>::iterator it = m.find('c');
if (it != m.end())
it->second = 42;
I like @sjr's answer however I prefer xargs vs -exec. I find xargs more versatile. For example with -P we can take advantage of multiple CPUs when it makes sense to do so.
find . -name '*.pdf' | xargs -P 5 -I % pdftotext % - | grep --with-filename --label="{}" --color "pattern"
You can achieve this like following :
map<string, int>::iterator it;
for (it = symbolTable.begin(); it != symbolTable.end(); it++)
{
std::cout << it->first // string (key)
<< ':'
<< it->second // string's value
<< std::endl;
}
With C++11 ( and onwards ),
for (auto const& x : symbolTable)
{
std::cout << x.first // string (key)
<< ':'
<< x.second // string's value
<< std::endl;
}
With C++17 ( and onwards ),
for (auto const& [key, val] : symbolTable)
{
std::cout << key // string (key)
<< ':'
<< val // string's value
<< std::endl;
}
You could try to find it via the command line.
find / -type f -name "php.ini"
Or you could add the following to a .htaccess
file in the root of your site.
php_value max_input_vars 6000
php_value suhosin.get.max_vars 6000
php_value suhosin.post.max_vars 6000
php_value suhosin.request.max_vars 6000
I simply set Copy Local = true
on the missing assembly and that worked. This of course happens by right clicking on the missing reference (which is stated in the error message) and selecting properties; as below:
This should then solve one problem as there might be more than one assembly causing the issue - what I did is I selected all assemblies and right click on them; selected properties; and set them all to Copy Local = true; and then republish.
I was facing the same issue earlier but I have somehow found the solution,
You can try reg.predict([[3300]])
.
The API used to allow scalar value but now you need to give a 2D array.
The following code works fine:
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
and generates as expected:
<form action="/Upload/Upload" enctype="multipart/form-data" method="post">
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
</form>
On the other hand if you are writing this code inside the context of other server side construct such as an if
or foreach
you should remove the @
before the using
. For example:
@if (SomeCondition)
{
using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
}
As far as your server side code is concerned, here's how to proceed:
[HttpPost]
public ActionResult Upload(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
file.SaveAs(path);
}
return RedirectToAction("Upload");
}

Use the View for your efforts in altering the position of the column: CREATE VIEW CORRECTED_POSITION AS SELECT co1_1, col_3, col_2 FROM UNORDERDED_POSITION should help.
This requests are made so some reports get produced where it is using SELECT * FROM [table_name]. Or, some business has a hierarchy approach of placing the information in order for better readability from the back end.
Thanks Dilip
With some Javascript you can get the exact width of the containing TD and then assign that directly to the input element.
The following is raw javascript but jQuery would make it cleaner...
var inputs = document.getElementsByTagName('input');
for (var i = 0; i < inputs.length; i++)
{
var el = inputs[i];
if (el.style.width == '100%')
{
var pEl = el.parentNode; // Assumes the parent node is the TD...
el.style.width = pEl.offsetWidth;
}
}
The issues with this solution are:
1) If you have your inputs contained in another element such as a SPAN then you will need loop up and find the TD because elements like SPANs will wrap the input and show its size rather then being limited to the size of the TD.
2) If you have padding or margins added at different levels then you might have to explicitly subtract that from [pEl.offsetWidth]. Depending on your HTML structure that can be calculated.
3) If the table columns are sized dynamically then changing the size of one element will cause the table to reflow in some browsers and you might get a stepped effect as you sequentially "fix" the input sizes. The solution is to assign specific widths to the column either as percentages or pixels OR collect the new widths and set them after. See the code below..
var inputs = document.getElementsByTagName('input');
var newSizes = [];
for (var i = 0; i < inputs.length; i++)
{
var el = inputs[i];
if (el.style.width == '100%')
{
var pEl = el.parentNode; // Assumes the parent node is the TD...
newSizes.push( { el: el, width: pEl.offsetWidth });
}
}
// Set the sizes AFTER to avoid stepping...
for (var i = 0; i < newSizes.length; i++)
{
newSizes[i].el.style.width = newSizes[i].width;
}
Yes, always will be slower create an object by reflection because the JVM cannot optimize the code on compilation time. See the Sun/Java Reflection tutorials for more details.
See this simple test:
public class TestSpeed {
public static void main(String[] args) {
long startTime = System.nanoTime();
Object instance = new TestSpeed();
long endTime = System.nanoTime();
System.out.println(endTime - startTime + "ns");
startTime = System.nanoTime();
try {
Object reflectionInstance = Class.forName("TestSpeed").newInstance();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
endTime = System.nanoTime();
System.out.println(endTime - startTime + "ns");
}
}
Assuming that MemoryStream name is ms
.
This code writes down MemoryStream to a file:
using (FileStream file = new FileStream("file.bin", FileMode.Create, System.IO.FileAccess.Write)) {
byte[] bytes = new byte[ms.Length];
ms.Read(bytes, 0, (int)ms.Length);
file.Write(bytes, 0, bytes.Length);
ms.Close();
}
and this reads a file to a MemoryStream :
using (MemoryStream ms = new MemoryStream())
using (FileStream file = new FileStream("file.bin", FileMode.Open, FileAccess.Read)) {
byte[] bytes = new byte[file.Length];
file.Read(bytes, 0, (int)file.Length);
ms.Write(bytes, 0, (int)file.Length);
}
In .Net Framework 4+, You can simply copy FileStream to MemoryStream and reverse as simple as this:
MemoryStream ms = new MemoryStream();
using (FileStream file = new FileStream("file.bin", FileMode.Open, FileAccess.Read))
file.CopyTo(ms);
And the Reverse (MemoryStream to FileStream):
using (FileStream file = new FileStream("file.bin", FileMode.Create, System.IO.FileAccess.Write))
ms.CopyTo(file);

Had need of this myself, so I wrote a String extension that both allows for URLEncoding strings, as well as the more common end goal, converting a parameter dictionary into "GET" style URL Parameters:
extension String {
func URLEncodedString() -> String? {
var escapedString = self.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)
return escapedString
}
static func queryStringFromParameters(parameters: Dictionary<String,String>) -> String? {
if (parameters.count == 0)
{
return nil
}
var queryString : String? = nil
for (key, value) in parameters {
if let encodedKey = key.URLEncodedString() {
if let encodedValue = value.URLEncodedString() {
if queryString == nil
{
queryString = "?"
}
else
{
queryString! += "&"
}
queryString! += encodedKey + "=" + encodedValue
}
}
}
return queryString
}
}
Enjoy!

</Image>
);
}

In CSS, we can cascade to the properties down the hierarchy but not in the oppostite direction. To modify the parent style on child event, probably use jQuery.
$el.closest('.parent').css('prop','value');
Did you create a Web Project? If you right click on the project and go to Properties > Project Facets is Dynamic Web Module selected?
Object initializers are cool because they allow you to set up a class inline. The tradeoff is that your class cannot be immutable. Consider:
public class Album
{
// Note that we make the setter 'private'
public string Name { get; private set; }
public string Artist { get; private set; }
public int Year { get; private set; }
public Album(string name, string artist, int year)
{
this.Name = name;
this.Artist = artist;
this.Year = year;
}
}
If the class is defined this way, it means that there isn't really an easy way to modify the contents of the class after it has been constructed. Immutability has benefits. When something is immutable, it is MUCH easier to determine that it's correct. After all, if it can't be modified after construction, then there is no way for it to ever be 'wrong' (once you've determined that it's structure is correct). When you create anonymous classes, such as:
new {
Name = "Some Name",
Artist = "Some Artist",
Year = 1994
};
the compiler will automatically create an immutable class (that is, anonymous classes cannot be modified after construction), because immutability is just that useful. Most C++/Java style guides often encourage making members const
(C++) or final
(Java) for just this reason. Bigger applications are just much easier to verify when there are fewer moving parts.
That all being said, there are situations when you want to be able quickly modify the structure of your class. Let's say I have a tool that I want to set up:
public void Configure(ConfigurationSetup setup);
and I have a class that has a number of members such as:
class ConfigurationSetup {
public String Name { get; set; }
public String Location { get; set; }
public Int32 Size { get; set; }
public DateTime Time { get; set; }
// ... and some other configuration stuff...
}
Using object initializer syntax is useful when I want to configure some combination of properties, but not neccesarily all of them at once. For example if I just want to configure the Name
and Location
, I can just do:
ConfigurationSetup setup = new ConfigurationSetup {
Name = "Some Name",
Location = "San Jose"
};
and this allows me to set up some combination without having to define a new constructor for every possibly permutation.
On the whole, I would argue that making your classes immutable will save you a great deal of development time in the long run, but having object initializer syntax makes setting up certain configuration permutations much easier.
You should use this example with AUTHID CURRENT_USER :
CREATE OR REPLACE PROCEDURE Create_sequence_for_tab (VAR_TAB_NAME IN VARCHAR2)
AUTHID CURRENT_USER
IS
SEQ_NAME VARCHAR2 (100);
FINAL_QUERY VARCHAR2 (100);
COUNT_NUMBER NUMBER := 0;
cur_id NUMBER;
BEGIN
SEQ_NAME := 'SEQ_' || VAR_TAB_NAME;
SELECT COUNT (*)
INTO COUNT_NUMBER
FROM USER_SEQUENCES
WHERE SEQUENCE_NAME = SEQ_NAME;
DBMS_OUTPUT.PUT_LINE (SEQ_NAME || '>' || COUNT_NUMBER);
IF COUNT_NUMBER = 0
THEN
--DBMS_OUTPUT.PUT_LINE('DROP SEQUENCE ' || SEQ_NAME);
-- EXECUTE IMMEDIATE 'DROP SEQUENCE ' || SEQ_NAME;
-- ELSE
SELECT 'CREATE SEQUENCE COMPTABILITE.' || SEQ_NAME || ' START WITH ' || ROUND (DBMS_RANDOM.VALUE (100000000000, 999999999999), 0) || ' INCREMENT BY 1'
INTO FINAL_QUERY
FROM DUAL;
DBMS_OUTPUT.PUT_LINE (FINAL_QUERY);
cur_id := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.parse (cur_id, FINAL_QUERY, DBMS_SQL.v7);
DBMS_SQL.CLOSE_CURSOR (cur_id);
-- EXECUTE IMMEDIATE FINAL_QUERY;
END IF;
COMMIT;
END;

The filter function wasn't working for me at all; maybe the more recent version of jquery doesn't perform as the version used in above code. Regardless; I used:
var black = $('.black');
var white = $('.white');
The selector will find every element classed under black or white. Button functions stay as stated above:
$('#showBlackButton').click(function() {
black.show();
white.hide();
});
$('#showWhiteButton').click(function() {
white.show();
black.hide();
});
I like PyInstaller - especially the "windowed" variant:
pyinstaller --onefile --windowed myscript.py
It will create one single *.exe file in a distination/folder.
Just add
position: relative;
top: 50%;
transform: translateY(-50%);
to the inner div.
What it does is moving the inner div's top border to the half height of the outer div (top: 50%;
) and then the inner div up by half its height (transform: translateY(-50%)
). This will work with position: absolute
or relative
.
Keep in mind that transform
and translate
have vendor prefixes which are not included for simplicity.
Codepen: http://codepen.io/anon/pen/ZYprdb
a.insert(a.end(), b.begin(), b.end());
or
a.insert(std::end(a), std::begin(b), std::end(b));
The second variant is a more generically applicable solution, as b
could also be an array. However, it requires C++11. If you want to work with user-defined types, use ADL:
using std::begin, std::end;
a.insert(end(a), begin(b), end(b));
Another option to include_once or require_once is to use class autoloading. http://php.net/manual/en/language.oop5.autoload.php
=>Create a new table directly with the following query:
CREATE TABLE table_name (Column_1 TEXT,Column_2 TEXT);
=>Now insert the data into table_name from existing_table with the following query:
INSERT INTO table_name (Column_1,Column_2) FROM existing_table;
=>Now drop the existing_table by following query:
DROP TABLE existing_table;
In Python3, you can:
print("%02d" % a)
Since hidden input does not trigger "change" event on change, I used MutationObserver to trigger this instead.
(Sometimes hidden input value changes are done by some other scripts you can't modify)
This does not work in IE10 and below
MutationObserver = window.MutationObserver || window.WebKitMutationObserver;
var trackChange = function(element) {
var observer = new MutationObserver(function(mutations, observer) {
if(mutations[0].attributeName == "value") {
$(element).trigger("change");
}
});
observer.observe(element, {
attributes: true
});
}
// Just pass an element to the function to start tracking
trackChange( $("input[name=foo]")[0] );
In the accepted answer by @chuck, there is a comment saying it will not work in the case of FK.
it worked for me, case of EF6 .Net4.7.2
public class OnCallDay

public int Id { get; set; }
//[Key]
[Index("IX_OnCallDateEmployee", 1, IsUnique = true)]
public DateTime Date { get; set; }
[ForeignKey("Employee")]
[Index("IX_OnCallDateEmployee", 2, IsUnique = true)]
public string EmployeeId { get; set; }
public virtual ApplicationUser Employee{ get; set; }
}
As the error says your router link should match the existing routes configured
It should be just routerLink="/about

After a lot of research, I finally figured this one out.
DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) { // Change `2.0` to the desired number of seconds.
// Code you want to be delayed
}
This creates the desired "wait" effect in Swift 3 and Swift 4.

I recommend to use SMO (Enable TCP/IP Network Protocol for SQL Server). However, it was not available in my case.
I rewrote the WMI commands from Krzysztof Kozielczyk to PowerShell.
# Enable TCP/IP
Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocol -Filter "InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'" |
Invoke-CimMethod -Name SetEnable
# Open the right ports in the firewall
New-NetFirewallRule -DisplayName 'MSSQL$SQLEXPRESS' -Direction Inbound -Action Allow -Protocol TCP -LocalPort 1433
# Modify TCP/IP properties to enable an IP address
$properties = Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocolProperty -Filter "InstanceName='SQLEXPRESS' and ProtocolName = 'Tcp' and IPAddressName='IPAll'"
$properties | ? { $_.PropertyName -eq 'TcpPort' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '1433' }
$properties | ? { $_.PropertyName -eq 'TcpPortDynamic' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '' }
# Restart SQL Server

If you are using python 3.6, this worked for me:
sudo apt-get install python3.6-tk
instead of
sudo apt-get install python3-tk

your panel class don't have a constructor that accepts a string
try change
RLS_strid_panel p = new RLS_strid_panel(namn1);
to
RLS_strid_panel p = new RLS_strid_panel();
p.setName1(name1);
We had connection string in web.config
with Data Source=localhost
, and there was this error (MSSQL was on the same machine). Changing it to actual `DOMAIN\MACHINE' helped, somewhy.
It can be usefull. Bindings dose not always work.
<select id="product" class="form-control" name="product" required
ng-model="issue.productId"
ng-change="getProductVersions()"
ng-options="p.id as p.shortName for p in products">
</select>
For example. You fill options list source model from rest-service. Selected value was known befor filling list and was set. After executing rest-request with $http list option be done. But selected option is not set. By unknown reasons AngularJS in shadow $digest executing not bind selected as it shuold be. I gotta use JQuery to set selected. It`s important! Angular in shadow add prefix to value of attr "value" for generated by ng-repeat optinos. For int it is "number:".
$scope.issue.productId = productId;
function activate() {
$http.get('/product/list')
.then(function (response) {
$scope.products = response.data;
if (productId) {
console.log("" + $("#product option").length);//for clarity
$timeout(function () {
console.log("" + $("#product option").length);//for clarity
$('#product').val('number:'+productId);
//$scope.issue.productId = productId;//not work at all
}, 200);
}

For those looking to use axios-mock-adapter in place of the mockfetch example in the Redux documentation for async testing, I successfully used the following:
describe('SignInUser', () => {
var history = {
push: function(str) {
expect(str).toEqual('/feed');
}
}
it('Dispatches authorization', () => {
let mock = new MockAdapter(axios);
mock.onPost(`${ROOT_URL}/auth/signin`, {
email: '[email protected]',
password: 'test'
}).reply(200, {token: 'testToken' });
const expectedActions = [ { type: types.AUTH_USER } ];
const store = mockStore({ auth: [] });
return store.dispatch(actions.signInUser({
email: '[email protected]',
password: 'test',
}, history)).then(() => {
expect(store.getActions()).toEqual(expectedActions);
});
});
In order to test a successful case for signInUser
in file actions/index.js:
export const signInUser = ({ email, password }, history) => async dispatch => {
const res = await axios.post(`${ROOT_URL}/auth/signin`, { email, password })
.catch(({ response: { data } }) => {
...
});
if (res) {
dispatch({ type: AUTH_USER }); // Test verified this
localStorage.setItem('token', res.data.token); // Test mocked this
history.push('/feed'); // Test mocked this
}
}
Given that this is being done with jest, the localstorage call had to be mocked. This was in file src/setupTests.js:
const localStorageMock = {
removeItem: jest.fn(),
getItem: jest.fn(),
setItem: jest.fn(),
clear: jest.fn()
};
global.localStorage = localStorageMock;
To generate a shared library you need first to compile your C code with the -fPIC
(position independent code) flag.
gcc -c -fPIC hello.c -o hello.o
This will generate an object file (.o), now you take it and create the .so file:
gcc hello.o -shared -o libhello.so
EDIT: Suggestions from the comments:
You can use
gcc -shared -o libhello.so -fPIC hello.c
to do it in one step. – Jonathan Leffler
I also suggest to add -Wall
to get all warnings, and -g
to get debugging information, to your gcc
commands. – Basile Starynkevitch

ThreadLocal will ensure accessing the mutable object by the multiple threads in the non synchronized method is synchronized, means making the mutable object to be immutable within the method.
This is achieved by giving new instance of mutable object for each thread try accessing it. So It is local copy to the each thread. This is some hack on making instance variable in a method to be accessed like a local variable. As you aware method local variable is only available to the thread, one difference is; method local variables will not available to the thread once method execution is over where as mutable object shared with threadlocal will be available across multiple methods till we clean it up.
By Definition:
The ThreadLocal class in Java enables you to create variables that can only be read and written by the same thread. Thus, even if two threads are executing the same code, and the code has a reference to a ThreadLocal variable, then the two threads cannot see each other's ThreadLocal variables.
Each Thread
in java contains ThreadLocalMap
in it.
Where
Key = One ThreadLocal object shared across threads.
value = Mutable object which has to be used synchronously, this will be instantiated for each thread.
Achieving the ThreadLocal:
Now create a wrapper class for ThreadLocal which is going to hold the mutable object like below (with or without initialValue()
).
Now getter and setter of this wrapper will work on threadlocal instance instead of mutable object.
If getter() of threadlocal didn't find any value with in the threadlocalmap of the Thread
; then it will invoke the initialValue() to get its private copy with respect to the thread.
class SimpleDateFormatInstancePerThread {
private static final ThreadLocal<SimpleDateFormat> dateFormatHolder = new ThreadLocal<SimpleDateFormat>() {
@Override
protected SimpleDateFormat initialValue() {
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd") {
UUID id = UUID.randomUUID();
@Override
public String toString() {
return id.toString();
};
};
System.out.println("Creating SimpleDateFormat instance " + dateFormat +" for Thread : " + Thread.currentThread().getName());
return dateFormat;
}
};
/*
* Every time there is a call for DateFormat, ThreadLocal will return calling
* Thread's copy of SimpleDateFormat
*/
public static DateFormat getDateFormatter() {
return dateFormatHolder.get();
}
public static void cleanup() {
dateFormatHolder.remove();
}
}
Now wrapper.getDateFormatter()
will call threadlocal.get()
and that will check the currentThread.threadLocalMap
contains this (threadlocal) instance.
If yes return the value (SimpleDateFormat) for corresponding threadlocal instance
else add the map with this threadlocal instance, initialValue().
Herewith thread safety achieved on this mutable class; by each thread is working with its own mutable instance but with same ThreadLocal instance. Means All the thread will share the same ThreadLocal instance as key, but different SimpleDateFormat instance as value.

As of npm version 3.8.6, you can use
npm install --prefix ./install/here <package>
to install in the specified directory. NPM automatically creates node_modules
folder even when a node_modules
directory already exists in the higher up hierarchy.
You can also have a package.json
in the current directory and then install it in the specified directory using --prefix
option:
npm install --prefix ./install/here
As of npm 6.0.0, you can use
npm install --prefix ./install/here ./
to install the package.json in current directory to "./install/here" directory. There is one thing that I have noticed on Mac that it creates a symlink to parent folder inside the node_modules directory. But, it still works.
NOTE: NPM honours the path that you've specified through the --prefix
option. It resolves as per npm documentation on folders, only when npm install
is used without the --prefix
option.
Change your input to this:
<input type='submit' value='submit request' onclick='return btnClick();'>
And return false in your function
function btnClick() {
if (!validData())
return false;
}
var number = 5000;
var percentX = 12;
var result;
function percentCalculation(a, b){
var c = (parseFloat(a)*parseFloat(b))/100;
return parseFloat(c);
}
result = percentCalculation(number, percentX); //calculate percentX% of number
Since the main
method is static
and the fxn()
method is not, you can't call the method without first creating a Two
object. So either you change the method to:
public static int fxn(int y) {
y = 5;
return y;
}
or change the code in main
to:
Two two = new Two();
x = two.fxn(x);
Read more on static
here in the Java Tutorials.
In my case there was another directory within my workspace, having the same jar file as the one in my project. I hadn't created that directory or anything in it. It was created by Eclipse I believe. I just erased that directory and it just runs ok.
For VS2010:
SET VS90COMNTOOLS=%VS100COMNTOOLS%

The IN
operator is nothing but a fancy OR
of '=' comparisons. In fact it is so 'nothing but' that in SQL 2000 there was a stack overflow bug due to expansion of the IN
into OR
s when the list contained about 10k entries (yes, there are people writing 10k IN entries...). So you can't use any wildcard matching in it.
If you assign the default value to selectedWorkout
and use [ngValue]
(which allows to use objects as value - otherwise only string is supported) then it should just do what you want:
<select class="form-control" name="sel"
[(ngModel)]="selectedWorkout"
(ngModelChange)="updateWorkout($event)">
<option *ngFor="let workout of workouts" [ngValue]="workout">
{{workout.name}}
</option>
</select>
Ensure that the value you assign to selectedWorkout
is the same instance than the one used in workouts
. Another object instance even with the same properties and values won't be recognized. Only object identity is checked.
update
Angular added support for compareWith
, that makes it easier to set the default value when [ngValue]
is used (for object values)
From the docs https://angular.io/api/forms/SelectControlValueAccessor
<select [compareWith]="compareFn" [(ngModel)]="selectedCountries"> <option *ngFor="let country of countries" [ngValue]="country"> {{country.name}} </option> </select>
compareFn(c1: Country, c2: Country): boolean { return c1 && c2 ? c1.id === c2.id : c1 === c2; }
This way a different (new) object instance can be set as default value and compareFn
is used to figure out if they should be considered equal (for example if the id
property is the same.

Regarding WSDL (meaning "SOAP") as being "heavy-weight". Heavy matters how? If the toolset is doing all the "heavy lifting" for you, then why does it matter?
I have never yet needed to consume a complicated REST API. When I do, I expect I'll wish for a WSDL, which my tools will gladly convert into a set of proxy classes, so I can just call what appear to be methods. Instead, I suspect that in order to consume a non-trivial REST-based API, it will be necessary to write by hand a substantial amount of "light-weight" code.
Even when that's all done, you still will have translated human-readable documentation into code, with all the attendant risk that the humans read it wrong. Since WSDL is a machine-readable description of the service, it's much harder to "read it wrong".
Just a note: since this post, I have had the opportunity to work with a moderately complicated REST service. I did, indeed, wish for a WSDL or the equivalent, and I did, indeed, have to write a lot of code by hand. In fact, a substantial part of the development time was spent removing the code duplication of all the code that called different service operations "by hand".
it works for me after changing MaxPermSize=512M to MaxPermSize=256M
if($("h1").is(":hidden")){
// your code..

I liked @Andomar's answer best, but I needed the column descriptions also. Here is his query modified to include those also. (Uncomment the last part of the WHERE clause to return only rows where either description is non-null).

INNER JOIN information_schema.columns col
ON col.table_name = tbl.table_name
LEFT JOIN sys.extended_properties tableProp
ON tableProp.major_id = object_id(tbl.table_schema + '.' + tbl.table_name)

I encountered this issue, also due to misconfiguration. I was using tomcat and in the server.xml had specified my connector as such:
<Connector port="17443" SSLEnabled="true"
protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keyAlias="wrong" keystorePass="secret"
keystoreFile="/ssl/right.jks" />
When i fixed it thusly:
<Connector port="17443" SSLEnabled="true"
protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keyAlias="right" keystorePass="secret"
keystoreFile="/ssl/right.jks" />
It worked as expected. In other words, verify that you not only have the right keystore, but that you have specified the correct alias underneath it. Thanks for the invaluable hint user396404.

I was looking for an integer value in named column, so I did the below:
int index = dgv_myDataGridView.CurrentCell.RowIndex;
int id = Convert.ToInt32(dgv_myDataGridView["ID", index].Value)
The good thing about this is that the column can be in any position in the grid view and you will still get the value.

other.component.ts
So final correct solution is :
import { Component, OnInit } from '@angular/core';
import { Location } from '@angular/common';
import { Router } from '@angular/router';
/* 'router' it must be in small case */
@Component({
selector: 'app-other',
templateUrl: './other.component.html',
styleUrls: ['./other.component.css']
})
export class OtherComponent implements OnInit {
public href: string = "";
url: string = "asdf";
constructor(private router : Router) {} // make variable private so that it would be accessible through out the component
ngOnInit() {
this.href = this.router.url;
console.log(this.router.url);
}
}
@ModelAttribute
is a Spring mapping of request parameters to a particular object type. so your parameters might look like userClient.username
and userClient.firstName
, etc. as MockMvc imitates a request from a browser, you'll need to pass in the parameters that Spring would use from a form to actually build the UserClient
object.
(i think of ModelAttribute is kind of helper to construct an object from a bunch of fields that are going to come in from a form, but you may want to do some reading to get a better definition)
1.) left <= root < right
2.) left < root <= right
3.) left < root < right, such that no duplicate keys exist.
I might have to go and dig out my algorithm books, but off the top of my head (3) is the canonical form.
(1) or (2) only come about when you start to allow duplicates nodes and you put duplicate nodes in the tree itself (rather than the node containing a list).
The following tools can be useful during development:
Access Token Debugger: Paste in an access token for details
https://developers.facebook.com/tools/debug/accesstoken/
Graph API Explorer: Test requests to the graph api after pasting in your access token
WinSCp now supports S3 protocol
First, make sure your AWS user with S3 access permissions has an “Access key ID” created. You also have to know the “Secret access key”. Access keys are created and managed on Users page of IAM Management Console.
Make sure New site node is selected.
On the New site node, select Amazon S3 protocol.
Enter your AWS user Access key ID and Secret access key

The C++ way would be to use std::stringstream or just plain string concatenations. C++ strings are mutable so the performance considerations of concatenation are less of a concern.
with regards to formatting, you can do all the same formatting on a stream, but in a different way, similar to cout
. or you can use a strongly typed functor which encapsulates this and provides a String.Format like interface e.g. boost::format
If you only need your CSS to be applied to one specific view, I'm using this handy snippet inside my controller:
$("body").addClass("mystate");
$scope.$on("$destroy", function() {
$("body").removeClass("mystate");
});
This will add a class to my body
tag when the state loads, and remove it when the state is destroyed (i.e. someone changes pages). This solves my related problem of only needing CSS to be applied to one state in my application.

As other answers state setting new ParametersAction
is the way to inject one or more environment variables, but when a job is already parameterised adding new action won't take effect. Instead you'll see two links to a build parameters pointing to the same set of parameters and the one you wanted to add will be null
.
Here is a snippet updating the parameters list in both cases (a parametrised and non-parametrised job):
import hudson.model.*
def build = Thread.currentThread().executable
def env = System.getenv()
def version = env['currentversion']
def m = version =~/\d{1,2}/
def minVerVal = m[0]+"."+m[1]
def newParams = null
def pl = new ArrayList<StringParameterValue>()
pl.add(new StringParameterValue('miniVersion', miniVerVal))
def oldParams = build.getAction(ParametersAction.class)
if(oldParams != null) {
newParams = oldParams.createUpdated(pl)
build.actions.remove(oldParams)
} else {
newParams = new ParametersAction(pl)
}
build.addAction(newParams)

Microsoft Edge Run Wrapper
https://github.com/mihula/RunEdge
You run it this way:
RunEdge.exe [URL]
Examples:
RunEdge.exe http://google.com
RunEdge.exe www.stackoverflow.com
It is not exactly new way how to do it, but it is wrapped as exe file, which could be useful in some situations. For me it is way how to start Edge from IBM Notes Basic client.
I came researching the options that I would have to do this, however, I believe the method I use is the simplest:
SELECT COUNT(*),
DATEADD(dd, DATEDIFF(dd, 0, date_field),0) as dtgroup
FROM TABLE
GROUP BY DATEADD(dd, DATEDIFF(dd, 0, date_field),0)
ORDER BY dtgroup ASC;
I come here with the same doubt but for Xamarin for Android, I have used the Sigrist answer to do this method after save my file:
private void UpdateGallery()
{
Intent mediaScanIntent = new Intent(Intent.ActionMediaScannerScanFile);
Java.IO.File file = new Java.IO.File(_path);
Android.Net.Uri contentUri = Android.Net.Uri.FromFile(file);
mediaScanIntent.SetData(contentUri);
Application.Context.SendBroadcast(mediaScanIntent);
}
and it solved my problem, Thx Sigrist. I put it here becouse i did not found an answare about this for Xamarin and i hope it can help other people.

" drop down value.
Now define your parameter - example:
Now you can use your parameter in your job / build pipeline, example:
Next to trigger the build with own/custom parameter, invoke the following URL (using either POST or GET):
http://JENKINS_SERVER_ADDRESS/job/YOUR_JOB_NAME/buildWithParameters?myparam=myparam_value
I had the same problem and it took me around one hour to figure out where i went wrong only to note that i had used a wrong app id....just go to your code and used a correct id here
window.fbAsyncInit = function() {
FB.init({
appId : '1740077446229063',//your app id
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : 'v2.5' // use graph api version 2.5
});
Assuming you know the width of the margin:
dt { float: left; width: 100px; }
dd { margin-left: 100px; }
you can write a hoc for this purpose and write a method call redirect, here is the code:
import React, {useState} from 'react';
import {Redirect} from "react-router-dom";
const RedirectHoc = (WrappedComponent) => () => {
const [routName, setRoutName] = useState("");
const redirect = (to) => {
setRoutName(to);
};
if (routName) {
return <Redirect to={"/" + routName}/>
}
return (
<>
<WrappedComponent redirect={redirect}/>
</>
);
};
export default RedirectHoc;
import matplotlib.pyplot as plt
image = plt.imread('images/my_image4.jpg')
plt.imshow(image)
Using 'matplotlib.pyplot.imread' is recommended by warning messages in jupyter.

Okay, this is a rather old topic but I thought I'd chip in as the 'correct' answer doesn't work well with CSS.
This solution basically prevents the click event from moving the page so we can get the scroll position first. Then we manually add the hash and the browser automatically triggers a hashchange event. We capture the hashchange event and scroll back to the correct position. A callback separates and prevents your code causing a delay by keeping your hash hacking in one place.
var hashThis = function( $elem, callback ){
var scrollLocation;
$( $elem ).on( "click", function( event ){
event.preventDefault();
scrollLocation = $( window ).scrollTop();
window.location.hash = $( event.target ).attr('href').substr(1);
});
$( window ).on( "hashchange", function( event ){
$( window ).scrollTop( scrollLocation );
if( typeof callback === "function" ){
callback();
}
});
}
hashThis( $( ".myAnchor" ), function(){
// do something useful!
});
The way is correct, but can be improved a bit with the extended set-syntax.
set "var=xyz"
Sets the var to the content until the last quotation mark, this ensures that no "hidden" spaces are appended.
Your code would look like
set "var1=A"
set "var2=B"
set "AB=hi"
set "newvar=%var1%%var2%"
echo %newvar% is the concat of var1 and var2
echo !%newvar%! is the indirect content of newvar
Have you tried something like this:
.styled-select select {
-moz-appearance:none; /* Firefox */
-webkit-appearance:none; /* Safari and Chrome */
appearance:none;
}
Haven't tested, but should work.
EDIT: It looks like Firefox doesn't support this feature up until version 35 (read more here)
There is a workaround here, take a look at jsfiddle
on that post.
There is a sum() method in underscore-java library.
Code example:
import com.github.underscore.lodash.U;
public class Main {
public static void main(String[] args) {
int sum = U.sum(java.util.Arrays.asList(1, 2, 3, 4));
System.out.println(sum);
// -> 10
}
}
awk ' { print ( $(NF-1) ) }' file
I faced the same problem, and there are a lot of solutions given in the answer, trying all these solutions took me quite some time, so here I would like to propose a methodical approach if you get this error.
Check for the following things, create/update if something is missing
If everything is fine, you can try following solutions in given order
Recompile the file/module
If that didn't fix the issue, try refreshing maven dependency and building the project using Maven -> Reimport
and Build -> Rebuild Project
Try mvn clean install -DskipTests
Try invalidating the IntelliJ cache and restarting the IDE, using File > Invalidate caches/ restart
Delete the .idea folder and reimport the project
Credit and Thanks to everyone who answered this question, you can refer to their answers for more description regarding each point.
I know this is an old question but here is my solution using HTML5 data attributes in MVC4:
<div id="dialog" title="Confirmation Required" data-url="@Url.Action("UndoAllPendingChanges", "Home")">
Are you sure about this?
</div>
JS code:
$("#dialog").dialog({
modal: true,
autoOpen: false,
buttons: {
"Confirm": function () {
window.location.href = $(this).data('url');
},
"Cancel": function () {
$(this).dialog("close");
}
}
});
$("#TheIdOfMyButton").click(function (e) {
e.preventDefault();
$("#dialog").dialog("open");
});
I wanted to make a simple and understandable example
if you call a method like this, your client will not know return type
var interestPoints = Mediator.Handle(new InterestPointTypeRequest
{
LanguageCode = request.LanguageCode,
AgentId = request.AgentId,
InterestPointId = request.InterestPointId,
});
Then you should say to compiler i know the return type is List<InterestPointTypeMap>
var interestPoints = Mediator.Handle<List<InterestPointTypeMap>>(new InterestPointTypeRequest
{
LanguageCode = request.LanguageCode,
AgentId = request.AgentId,
InterestPointId = request.InterestPointId,
InterestPointTypeId = request.InterestPointTypeId
});
the compiler will no longer be mad at you for knowing the return type
Use a linked list. It was designed for this exact situation.
If you still need the dictionary O(1) lookups, use both a dictionary and a linked list.
The actual answer is "use mutation observers" (as outlined in this question: Determining if a HTML element has been added to the DOM dynamically), however support (specifically on IE) is limited (http://caniuse.com/mutationobserver).
So the actual ACTUAL answer is "Use mutation observers.... eventually. But go with Jose Faeti's answer for now" :)
Make your object something like
public class MyObject : IComparable
{
public string a;
public string b;
virtual public int CompareTo(object obj)
{
if (obj is MyObject)
{
var compareObj = (MyObject)obj;
if (this.a.CompareTo(compareObj.a) == 0)
{
// compare second value
return this.b.CompareTo(compareObj.b);
}
return this.a.CompareTo(compareObj.b);
}
else
{
throw new ArgumentException("Object is not a MyObject ");
}
}
}
also note that the returns for CompareTo :
http://msdn.microsoft.com/en-us/library/system.icomparable.compareto.aspx
Then, if you have a List of MyObject, call .Sort() ie
var objList = new List<MyObject>();
objList.Sort();
cyclops-react StreamUtils has a reverse Stream method (javadoc).
StreamUtils.reverse(Stream.of("1", "2", "20", "3"))
.forEach(System.out::println);
It works by collecting to an ArrayList and then making use of the ListIterator class which can iterate in either direction, to iterate backwards over the list.
If you already have a List, it will be more efficient
StreamUtils.reversedStream(Arrays.asList("1", "2", "20", "3"))
.forEach(System.out::println);
You Can create a Linear layout containing an array of TextView (mDots). To represent the textView as Dots provide this HTML source in your code . refer my code . I got this information from Youtube Channel TVAC Studio . here the code : `
addDotsIndicator(0);
viewPager.addOnPageChangeListener(viewListener);
}
public void addDotsIndicator(int position)
{
mDots = new TextView[5];
mDotLayout.removeAllViews();
for (int i = 0; i<mDots.length ; i++)
{
mDots[i]=new TextView(this);
mDots[i].setText(Html.fromHtml("•")); //HTML for dots
mDots[i].setTextSize(35);
mDots[i].setTextColor(getResources().getColor(R.color.colorAccent));
mDotLayout.addView(mDots[i]);
}
if(mDots.length>0)
{
mDots[position].setTextColor(getResources().getColor(R.color.orange));
}
}
ViewPager.OnPageChangeListener viewListener = new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int
positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
addDotsIndicator(position);
}
@Override
public void onPageScrollStateChanged(int state) {
}
};`
This css works for me:
.dataTables_paginate {
float: none !important;
text-align: center !important;
}
In C (not C++), you have to declare struct variables like:
struct myStruct myVariable;
In order to be able to use myStruct myVariable;
instead, you can typedef
the struct:
typedef struct myStruct someStruct;
someStruct myVariable;
You can combine struct
definition and typedef
s it in a single statement which declares an anonymous struct
and typedef
s it.
typedef struct { ... } myStruct;
Rails.application.routes.default_url_options[:host]= 'localhost:3000'
In the developemnt.rb / test.rb, can be more concise as following:
Rails.application.configure do
# ... other config ...
routes.default_url_options[:host] = 'localhost:3000'
end
Change:
<select name="select2" ...
To:
<select name="select2[]" ...
A string can be converted to an array of characters by calling the ToCharArray
string's method.
var characters = stringValue.ToCharArray();
An object of type string[]
is not a string, but an array of strings. You cannot convert an array of strings to an array of characters by just calling a method like ToCharArray
. To be more correct there isn't any method in the .NET framework that does this thing. You could however declare an extension method to do this, but this is another discussion.
If your intention is to build an array of the characters that make up the strings you have in your array, you could do so by calling the ToCharArray
method on each string of your array.
You could use \r\n
, or System.Environment.NewLine
.
There may be 2 spaces after the text, please confirm. You can use LTRIM
and RTRIM
functions also right?
LTRIM(RTRIM(ProductAlternateKey))
Maybe the extra space isn't ordinary spaces (ASCII 32, soft space)? Maybe they are "hard space", ASCII 160?
ltrim(rtrim(replace(ProductAlternateKey, char(160), char(32))))
You can trim that up a bit like this:
if ( x.y !== undefined ) ...
UPDATE [table]
SET [column] = REPLACE([column], '/foo/', '/bar/')
If you want to avoid closures, and happy to use facades, the following keeps things nice and clean:
try {
\DB::beginTransaction();
$user = \Auth::user();
$user->fill($request->all());
$user->push();
\DB::commit();
} catch (Throwable $e) {
\DB::rollback();
}
If any statements fail, commit will never hit, and the transaction won't process.
I think JavaScript's indebtedness to Scheme is obvious here. Scheme not only has let, but has let*, let*-values, let-syntax, and let-values. (See, The Scheme Programming Language, 4th Ed.).
((The choice adds further credence to the notion that JavaScript is Lispy, but--before we get carried away--not homoiconic.))))
You have to edit httpd.conf
and find this line: Listen 127.0.0.1:80
Then write down your desired IP you set for LAN. Don't use automatic IP.
e.g.: Listen 192.168.137.1:80
I used 192.167.137.1
as my LAN IP of Windows 7. Restart Apache and enjoy sharing.
If you have MySQL version >= 5.7, then you can try this:

Simple one without rank :

Sample code testing div() and combined division & mod. I compiled these with gcc -O3, I had to add the call to doNothing to stop the compiler from optimising everything out (output would be 0 for the division + mod solution).
Take it with a grain of salt:
#include <stdio.h>
#include <sys/time.h>
#include <stdlib.h>
extern doNothing(int,int); // Empty function in another compilation unit
int main() {
int i;
struct timeval timeval;
struct timeval timeval2;
div_t result;
gettimeofday(&timeval,NULL);
for (i = 0; i < 1000; ++i) {
result = div(i,3);
doNothing(result.quot,result.rem);
}
gettimeofday(&timeval2,NULL);
printf("%d",timeval2.tv_usec - timeval.tv_usec);
}
Outputs: 150
#include <stdio.h>
#include <sys/time.h>
#include <stdlib.h>
extern doNothing(int,int); // Empty function in another compilation unit
int main() {
int i;
struct timeval timeval;
struct timeval timeval2;
int dividend;
int rem;
gettimeofday(&timeval,NULL);
for (i = 0; i < 1000; ++i) {
dividend = i / 3;
rem = i % 3;
doNothing(dividend,rem);
}
gettimeofday(&timeval2,NULL);
printf("%d",timeval2.tv_usec - timeval.tv_usec);
}
Outputs: 25
Git is supposed to understand what files already exist on the server, unless you somehow made a huge difference to your tree and the new changes need to be sent.
To create a new branch with a copy of your current state
git checkout -b new_branch #< create a new local branch with a copy of your code
git push origin new_branch #< pushes to the server
Can you please describe the steps you did to understand what might have made your repository need to send that much to the server.

As per my understanding you need to show 3 tables data in one html table using asp.net with c#.
I think best you just create one dataset with 3 DataTable object.
Bind that dataset to GriView directly on page load.
You could use:
if(!this.form.checkbox.checked)
{
alert('You must agree to the terms first.');
return false;
}
(demo page).
<input type="checkbox" name="checkbox" value="check" />
<input type="submit" name="email_submit" value="submit" onclick="if(!this.form.checkbox.checked){alert('You must agree to the terms first.');return false}" />
false
from an inline event handler will prevent the default action from taking place (in this case, submitting the form).!
is the Boolean NOT operator.this
is the submit button because it is the element the event handler is attached to..form
is the form the submit button is in..checkbox
is the control named "checkbox" in that form..checked
is true if the checkbox is checked and false if the checkbox is unchecked.Add your <script>
to the bottom of your <body>
, or add an event listener for DOMContentLoaded
following this StackOverflow question.
If that script executes in the <head>
section of the code, document.getElementsByClassName(...)
will return an empty array because the DOM is not loaded yet.
You're getting the Type Error
because you're referencing search_span[0]
, but search_span[0]
is undefined
.
This works when you execute it in Dev Tools because the DOM is already loaded.
The Dr. Memory (http://drmemory.org) tool comes with a system call tracing tool called drstrace that lists all system calls made by a target application along with their arguments: http://drmemory.org/strace_for_windows.html
For programmatically enforcing system call policies, you could use the same underlying engines as drstrace: the DynamoRIO tool platform (http://dynamorio.org) and the DrSyscall system call monitoring library (http://drmemory.org/docs/page_drsyscall.html). These use dynamic binary translation technology, which does incur some overhead (20%-30% in steady state, but much higher when running new code such as launching a big desktop app), which may or may not be suitable for your purposes.
In your join or where clause, use the Date
property of the column. Behind the scenes, this executes a CONVERT(DATE, <expression>)
operation. This should allow you to compare dates without the time.
It doesn't?

On my Windows machine it was not taking:
chere -i -t mintty
Because mintty shell was not available,but you might have choice of various other shells like ash bash cmd dash mksh pdksh posh tcsh zsh passwd.
so I used :
chere -i -s bash
how about something like this ...
a.register:link{
color:#FFFFFF;
}
well first of all you need to install this packege below:
sudo apt install ipython
jupyter nbconvert --to script [YOUR_NOTEBOOK].ipynb
two option is avaliable either --to python or --to=python mine was like this works fine: jupyter nbconvert --to python while.ipynb
jupyter nbconvert --to python while.ipynb

pip3 install ipython
if it does not work for you try, by pip3.

Here's the GNU version of printf
... you can see it passing in stdout
to vfprintf
:
__printf (const char *format, ...)
{
va_list arg;
int done;
va_start (arg, format);
done = vfprintf (stdout, format, arg);
va_end (arg);
return done;
}
Here's a link to vfprintf
... all the formatting 'magic' happens here.
The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf
equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)
I know this question has been answered but the answers i found here didn't work for my scenario ( or for Windows ).
I am using windows 10 laptop with PHP 7.2 in Xampp v3.2.4.
$command = 'php Cron.php send_email "'. $id .'"';
if ( substr(php_uname(), 0, 7) == "Windows" )
{
//windows
pclose(popen("start /B " . $command . " 1> temp/update_log 2>&1 &", "r"));
}
else
{
//linux
shell_exec( $command . " > /dev/null 2>&1 &" );
}
This worked perfectly for me.
I hope it will help someone with windows. Cheers.
The way I'm doing it now is basically like this:
The HTML:
<textarea id="myText">
Lorem ipsum...
</textarea>
<button onclick="sendMail(); return false">Send</button>
The Javascript:
function sendMail() {
var link = "mailto:[email protected]"
+ "[email protected]"
+ "&subject=" + encodeURIComponent("This is my subject")
+ "&body=" + encodeURIComponent(document.getElementById('myText').value)
;
window.location.href = link;
}
This, surprisingly, works rather well. The only problem is that if the body is particularly long (somewhere over 2000 characters), then it just opens a new email but there's no information in it. I suspect that it'd be to do with the maximum length of the URL being exceeded.
Combining some of the suggestions above, using jQuery, here is what I did:
input[type='file'].unused {
color: transparent;
}
And:
$(function() {
$("input[type='file'].unused").click( function() {$(this).removeClass('unused')});
};
And put the class "unused" on your file inputs. This is simple and works pretty well.
A copy-pastable solution similar to the one of ghostdog:
def get_all_filepaths(root_path, ext):
"""
Search all files which have a given extension within root_path.
This ignores the case of the extension and searches subdirectories, too.
Parameters
----------
root_path : str
ext : str

-------
list of str

--------
>>> get_all_filepaths('/run', '.lock')
['/run/unattended-upgrades.lock',
'/run/mlocate.daily.lock',
'/run/xtables.lock',
'/run/mysqld/mysqld.sock.lock',
'/run/postgresql/.s.PGSQL.5432.lock',
'/run/network/.ifstate.lock',
'/run/lock/asound.state.lock']
"""
import os
all_files = []
for root, dirs, files in os.walk(root_path):
for filename in files:
if filename.lower().endswith(ext):
all_files.append(os.path.join(root, filename))
return all_files
I tried the above scenario and got the same error 5 (access denied). I did a deep dive and found that the file .bak should have access to the SQL service account. If you are not sure, type services.msc in Start -> Run then check for SQL Service logon account.
Then go to the file, right-click and select Security tab in Properties, then edit to add the new user.
Finally then give full permission to it in order to give full access.
Then from SSMS try to restore the backup.

Auto Animated Scrolling
In addition, here are functions for scrolling a <div>
fully to the left and right. The only thing we change here is we make a check to see if the full extension of the scroll has been utilised before making a recursive call to scroll again.

In case anyone else has the same issue as this on
Centos, try:
yum install python-lxml
Ubuntu
sudo apt-get install -y python-lxml
worked for me.
You can do:
var buf = Buffer.from(bufStr, 'utf8');
But this is a bit silly, so another suggestion would be to copy the minimal amount of code out of the called function to allow yourself access to the original buffer. This might be quite easy or fairly difficult depending on the details of that library.
You should be able to add
target="_blank"
like

If you are using Hibernate 5+, then query will be modified as
Long count = session.createQuery("select count(1) from Book")
.getSingleResult();
Or if you Need TypedQuery
Long count = session.createQuery("select count(1) from Book",Long.class)
.getSingleResult();
window.scrollTo(0,1);
this will help you but this javascript is may not work in all browsers
I use the following template in my projects:
angular.module("AppName.moduleName", [])
/**
* @ngdoc controller
* @name AppName.moduleName:ControllerNameController
* @description Describe what the controller is responsible for.
**/
.controller("ControllerNameController", function (dependencies) {
/* type */ $scope.modelName = null;
/* type */ $scope.modelName.modelProperty1 = null;
/* type */ $scope.modelName.modelPropertyX = null;
/* type */ var privateVariable1 = null;
/* type */ var privateVariableX = null;
(function init() {
// load data, init scope, etc.
})();
$scope.modelName.publicFunction1 = function () /* -> type */ {
// ...
};
$scope.modelName.publicFunctionX = function () /* -> type */ {
// ...
};
function privateFunction1() /* -> type */ {
// ...
}
function privateFunctionX() /* -> type */ {
// ...
}
});
SapphireSun is quite right. You can just use lst.sort()
. Python's sort implementation (TimSort) check if the list is already sorted. If so sort() will completed in linear time. Sounds like a Pythonic way to ensure a list is sorted ;)
Yes, the task gets blocked in the read() system call. Another task which is ready runs, or if no other tasks are ready, the idle task (for that CPU) runs.
A normal, blocking disc read causes the task to enter the "D" state (as others have noted). Such tasks contribute to the load average, even though they're not consuming the CPU.
Some other types of IO, especially ttys and network, do not behave quite the same - the process ends up in "S" state and can be interrupted and doesn't count against the load average.
See ?read.table
. Basically, when you use read.table
, you specify a number indicating the column:
##Row names in the first column
read.table(filname.txt, row.names=1)
In your Safari menu bar click Safari > Preferences & then select the Advanced tab.
Select: "Show Develop menu in menu bar"
Now you can click Develop in your menu bar and choose Show Web Inspector
You can also right-click and press "Inspect element".
Solution:
public Response Get(string jsonData) {
var json = JsonConvert.DeserializeObject<modelname>(jsonData);
var data = StoredProcedure.procedureName(json.Parameter, json.Parameter, json.Parameter, json.Parameter);
return data;
}
Model:
public class modelname {
public long parameter{ get; set; }
public int parameter{ get; set; }
public int parameter{ get; set; }
public string parameter{ get; set; }
}
The accepted answer did not work for me in all browsers, but following css did work for me:
tr
{
display: table-row-group;
page-break-inside:avoid;
page-break-after:auto;
}
The html structure was:
<table>
<thead>
<tr></tr>
</thead>
<tbody>
<tr></tr>
<tr></tr>
...
</tbody>
</table>
In my case, there were some additional issues with the thead tr
, but this resolved the original issue of keeping the table rows from breaking.
Because of the header issues, I ultimately ended up with:
#theTable td *
{
page-break-inside:avoid;
}
This didn't prevent rows from breaking; just each cell's content.
You can add style for :after a like html code.
For example:
var value = 22;
body.append('<style>.wrapper:after{border-top-width: ' + value + 'px;}</style>');
That header doesn't exist in standard C++. It was part of some pre-1990s compilers, but it is certainly not part of C++.
Use #include <iostream>
instead. And all the library classes are in the std::
namespace, for example std::cout
.
Also, throw away any book or notes that mention the thing you said.
Considering that your package scanning is correctly set either through XML configuration or annotation based configuration.
You will need a @Repository
on your ClientRepository
implementation as well to allow Spring to use it in an @Autowired
. Since it's not here we can only suppose that's what's missing.
As a side note, it would be cleaner to put your @Autowired
/@Qualifier
directly on your member if the setter method is only used for the @Autowired
.
@Autowired
@Qualifier("clientRepository")
private ClientRepository clientRepository;
Lastly, you don't need the @Qualifier
is there is only one class implementing the bean definition so unless you have several implementation of ClientService
and ClientRepository
you can remove the @Qualifier
You can use the expression pipeline to achieve this:
public static Func<object, object> Caster(Type type)
{
var inputObject = Expression.Parameter(typeof(object));
return Expression.Lambda<Func<object,object>>(Expression.Convert(inputObject, type), inputPara).Compile();
}
which you can invoke like:
object objAsDesiredType = Caster(desiredType)(obj);
Drawbacks: The compilation of this lambda is slower than nearly all other methods mentioned already
Advantages: You can cache the lambda, then this should be actually the fastest method, it is identical to handwritten code at compile time
