Not certain what the HTML looks like (that would help with answers). If it's
<div class="testimonials content">stuff</div>
then simply remove the space in your css. A la...
.testimonials.content { css here }
UPDATE:
Okay, after seeing HTML see if this works...
.testimonials .wrapper .content { css here }
or just
.testimonials .wrapper { css here }
or
.desc-container .wrapper { css here }
all 3 should work.
Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "]
with array("title" => "Welcome ")
Adapted from a grep in python.
Accepts a list of filenames via [2:]
, does no exception handling:
#!/usr/bin/env python
import re, sys, os
for f in filter(os.path.isfile, sys.argv[2:]):
for line in open(f).readlines():
if re.match(sys.argv[1], line):
print line
sys.argv[1]
resp sys.argv[2:]
works, if you run it as an standalone executable, meaning
chmod +x
first
1) check if service declaration in manifest is nested in application tag
<application>
<service android:name="" />
</application>
2) check if your service.java
is in the same package or diff package as the activity
<application>
<!-- service.java exists in diff package -->
<service android:name="com.package.helper.service" />
</application>
<application>
<!-- service.java exists in same package -->
<service android:name=".service" />
</application>
I suggest the use of htop, as a better alternative to top.

After looking for an answer for this question I found a brilliant explanation with an example that I would like to share with you.
You can watch a video that demonstrate the differences HERE
In this example we have this given code:
public interface IEmployeeRepository
{
IEnumerable<Employee> GetAllEmployees();
Employee Add(Employee employee);
}
public class Employee
{
public int Id { get; set; }
public string Name { get; set; }
}
public class MockEmployeeRepository : IEmployeeRepository
{
private List<Employee> _employeeList;
public MockEmployeeRepository()
{
_employeeList = new List<Employee>()
{
new Employee() { Id = 1, Name = "Mary" },
new Employee() { Id = 2, Name = "John" },
new Employee() { Id = 3, Name = "Sam" },
};
}
public Employee Add(Employee employee)
{
employee.Id = _employeeList.Max(e => e.Id) + 1;
_employeeList.Add(employee);
return employee;
}
public IEnumerable<Employee> GetAllEmployees()
{
return _employeeList;
}
}
HomeController
public class HomeController : Controller
{
private IEmployeeRepository _employeeRepository;
public HomeController(IEmployeeRepository employeeRepository)
{
_employeeRepository = employeeRepository;
}
[HttpGet]
public ViewResult Create()
{
return View();
}
[HttpPost]
public IActionResult Create(Employee employee)
{
if (ModelState.IsValid)
{
Employee newEmployee = _employeeRepository.Add(employee);
}
return View();
}
}
Create View
@model Employee
@inject IEmployeeRepository empRepository
<form asp-controller="home" asp-action="create" method="post">
<div>
<label asp-for="Name"></label>
<div>
<input asp-for="Name">
</div>
</div>
<div>
<button type="submit">Create</button>
</div>
<div>
Total Employees Count = @empRepository.GetAllEmployees().Count().ToString()
</div>
</form>
Startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
services.AddSingleton<IEmployeeRepository, MockEmployeeRepository>();
}
Copy-paste this code and press on the create button in the view and switch between
AddSingleton
, AddScoped
and AddTransient
you will get each time a different result that will might help you understand this.
AddSingleton() - As the name implies, AddSingleton() method creates a Singleton service. A Singleton service is created when it is first requested. This same instance is then used by all the subsequent requests. So in general, a Singleton service is created only one time per application and that single instance is used throughout the application life time.
AddTransient() - This method creates a Transient service. A new instance of a Transient service is created each time it is requested.
AddScoped() - This method creates a Scoped service. A new instance of a Scoped service is created once per request within the scope. For example, in a web application it creates 1 instance per each http request but uses the same instance in the other calls within that same web request.
I thought I'd share a situation where my team decided to include .c files. Our archicture largely consists of modules that are decoupled through a message system. These message handlers are public, and call many local static worker functions to do their work. The problem came about when trying to get coverage for our unit test cases, as the only way to exercise this private implementation code was indirectly through the public message interface. With some worker functions knee-deep in the stack, this turned out to be a nightmare to achieve proper coverage.
Including the .c files gave us a way to reach the cog in the machine we were interesting in testing.
You can do this:
#include <cmath>
#ifndef M_PI
#define M_PI (3.14159265358979323846)
#endif
If M_PI
is already defined in cmath
, this won't do anything else than include cmath
. If M_PI
isn't defined (which is the case for example in Visual Studio), it will define it. In both cases, you can use M_PI
to get the value of pi.
This value of pi comes from Qt Creator's qmath.h.
Hope this will help someone... Here's a little PHP script I wrote in case you need to copy some columns but not others, and/or the columns are not in the same order on both tables. As long as the columns are named the same, this will work. So if table A has [userid, handle, something] and tableB has [userID, handle, timestamp], then you'd "SELECT userID, handle, NOW() as timestamp FROM tableA", then get the result of that, and pass the result as the first parameter to this function ($z). $toTable is a string name for the table you're copying to, and $link_identifier is the db you're copying to. This is relatively fast for small sets of data. Not suggested that you try to move more than a few thousand rows at a time this way in a production setting. I use this primarily to back up data collected during a session when a user logs out, and then immediately clear the data from the live db to keep it slim.
function mysql_multirow_copy($z,$toTable,$link_identifier) {
$fields = "";
for ($i=0;$i<mysql_num_fields($z);$i++) {
if ($i>0) {
$fields .= ",";
}
$fields .= mysql_field_name($z,$i);
}
$q = "INSERT INTO $toTable ($fields) VALUES";
$c = 0;
mysql_data_seek($z,0); //critical reset in case $z has been parsed beforehand. !
while ($a = mysql_fetch_assoc($z)) {
foreach ($a as $key=>$as) {
$a[$key] = addslashes($as);
next ($a);
}
if ($c>0) {
$q .= ",";
}
$q .= "('".implode(array_values($a),"','")."')";
$c++;
}
$q .= ";";
$z = mysql_query($q,$link_identifier);
return ($q);
}
For View : (Most Recommended)
It works for all type of UIView
subclass (view, textfiled, label, etc...) using UIView extension
It is more simple and convenient. But the only condition is the view
must contain an auto layout.
extension UIView {
enum Line_Position {
case top
case bottom
}
func addLine(position : Line_Position, color: UIColor, height: Double) {
let lineView = UIView()
lineView.backgroundColor = color
lineView.translatesAutoresizingMaskIntoConstraints = false // This is important!
self.addSubview(lineView)
let metrics = ["width" : NSNumber(value: height)]
let views = ["lineView" : lineView]
self.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "H:|[lineView]|", options:NSLayoutConstraint.FormatOptions(rawValue: 0), metrics:metrics, views:views))
switch position {
case .top:
self.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|[lineView(width)]", options:NSLayoutConstraint.FormatOptions(rawValue: 0), metrics:metrics, views:views))
break
case .bottom:
self.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:[lineView(width)]|", options:NSLayoutConstraint.FormatOptions(rawValue: 0), metrics:metrics, views:views))
break
}
}
}
How to use?
// UILabel
self.lblDescription.addLine(position: .bottom, color: UIColor.blue, height: 1.0)
// UITextField
self.txtArea.addLine(position: .bottom, color: UIColor.red, height: 1.0)
Here is my function I use. n - string length you want to generate
function generateRandomNumber(n) {_x000D_
return Math.floor(Math.random() * (9 * Math.pow(10, n - 1))) + Math.pow(10, n - 1);_x000D_
}
_x000D_
The path should be something like: "Images\a.bmp"
. (Note the lack of a leading slash, and the slashes being back slashes.)
And then:
pictureBox1.Image = Image.FromFile(@"Images\a.bmp");
I just tried it to make sure, and it works. This is besides the other answer that you got - to "copy always".
Number("2,299.00".split(',').join('')); // 2299
The split function splits the string into an array using "," as a separator and returns an array.
The join function joins the elements of the array returned from the split function.
The Number() function converts the joined string to a number.
" ".join(my_list)
you need to join with a space not an empty string ...
Out of curiosity, I found a box with a GNU version of sed
(v4.1.5) and tested the (uncached) performance of two approaches suggested so far, using an 11M line text file:
$ wc -l input
11771722 input
$ time head -1000 input > output; time tail -n +1000 input > input.tmp; time cp input.tmp input; time rm input.tmp
real 0m1.165s
user 0m0.030s
sys 0m1.130s
real 0m1.256s
user 0m0.062s
sys 0m1.162s
real 0m4.433s
user 0m0.033s
sys 0m1.282s
real 0m6.897s
user 0m0.000s
sys 0m0.159s
$ time head -1000 input > output && time sed -i '1,+999d' input
real 0m0.121s
user 0m0.000s
sys 0m0.121s
real 0m26.944s
user 0m0.227s
sys 0m26.624s
This is the Linux I was working with:
$ uname -a
Linux hostname 2.6.18-128.1.1.el5 #1 SMP Mon Jan 26 13:58:24 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
For this test, at least, it looks like sed
is slower than the tail
approach (27 sec vs ~14 sec).
you can use this solution it is working for me
<span th:text="${#objects.nullSafe(doctor?.cabinet?.name,'')}"></span>
Highlighting with your mouse only highlights characters on the terminal. VI doesn't really get this information, so you have to highlight differently.
Press 'v' to enter a select mode, and use arrow keys to move that around. To delete, press x. To select lines at a time, press shift+v. To select blocks, try ctrl+v. That's good for, say, inserting lots of comment lines in front of your code :).
I'm OK with VI, but it took me a while to improve. My work mates recommended me this cheat sheet. I keep a printout on the wall for those odd moments when I forget something.
Happy hacking!
Only install the Service Pack (VS10sp1-KB983509.msp) wasn't enough to me.
I had to uninstall the Visual Studio Team Explorer 2010 to continue the installation :)
USE Master GO

Since you're returning a string as JSON, that string will include the opening and closing quotes in the raw response. So your response should probably look like:
"abc123XYZ=="
or whatever...You can try confirming this with Fiddler.
My guess is that the result.Content
is the raw string, including the quotes. If that's the case, then result.Content
will need to be deserialized before you can use it.
On Linux/Unix servers, you can execute a job in the background by using proc_open:
$descriptorspec = array(
array('pipe', 'r'), // stdin
array('file', 'myfile.txt', 'a'), // stdout
array('pipe', 'w'), // stderr
);
$proc = proc_open('php email_script.php &', $descriptorspec, $pipes);
The &
being the important bit here. The script will continue even if the original script has ended.
A couple of problems, actually:
First, in that project you uploaded for us, the segue does not bear the "segue1" identifier:
no identifier
You should fill in that identifier if you haven't already.
Second, as you're pushing from table view to table view, you're calling initWithNibName to create a view controller. You really want to use instantiateViewControllerWithIdentifier.
The GNU guys REALLY messed up when they introduced recursive file searching to grep. grep is for finding REs in files and printing the matching line (g/re/p remember?) NOT for finding files. There's a perfectly good tool with a very obvious name for FINDing files. Whatever happened to the UNIX mantra of do one thing and do it well?
Anyway, here's how you'd do what you want using the traditional UNIX approach (untested):
find /path/to/folder -type f -print |
while IFS= read -r file
do
awk -v old="$oldstring" -v new="$newstring" '
BEGIN{ rlength = length(old) }
rstart = index($0,old) { $0 = substr($0,rstart-1) new substr($0,rstart+rlength) }
{ print }
' "$file" > tmp &&
mv tmp "$file"
done
Not that by using awk/index() instead of sed and grep you avoid the need to escape all of the RE metacharacters that might appear in either your old or your new string plus figure out a character to use as your sed delimiter that can't appear in your old or new strings, and that you don't need to run grep since the replacement will only occur for files that do contain the string you want. Having said all of that, if you don't want the file timestamp to change if you don't modify the file, then just do a diff on tmp and the original file before doing the mv or throw in an fgrep -q before the awk.
Caveat: The above won't work for file names that contain newlines. If you have those then let us know and we can show you how to handle them.
This code was very helpful for me. Maybe it could be for you also
wb.Navigate(url);
while(wb.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}
MessageBox.Show("Loaded");
I thing these two links have a wide discussion on your problem related stuff. fb:ref clear cashes by calling
fbml.refreshRefUrl
like this
<tt>fbml.refreshRefUrl("http://www.mysite.com/someurl.php")
You can study the related stuff from here fb:ref. I hope it will work for you
Also note that some plugins (remote-resources comes to mind) use a really old library that only accepts proxy configuration through MAVEN_OPTS;
-Dhttp.proxyHost=<host> -Dhttp.proxyPort=<port> -Dhttps.proxyHost=<host> -Dhttps.proxyPort=<port>
You might be stuck on auth for this one.
Intel HD Graphics is usually the on-CPU graphics chip in newer Core i3/i5/i7 processors.
As far as I know it doesn't support CUDA (which is a proprietary NVidia technology), but OpenCL is supported by NVidia, ATi and Intel.
TLDR; The formula is n(n-1)/2
where n
is the number of items in the set.
To find the number of unique pairs in a set, where the pairs are subject to the commutative property (AB = BA)
, you can calculate the summation of 1 + 2 + ... + (n-1)
where n
is the number of items in the set.
The reasoning is as follows, say you have 4 items:
A
B
C
D
The number of items that can be paired with A
is 3, or n-1
:
AB
AC
AD
It follows that the number of items that can be paired with B
is n-2
(because B
has already been paired with A
):
BC
BD
and so on...
(n-1) + (n-2) + ... + (n-(n-1))
which is the same as
1 + 2 + ... + (n-1)
or
n(n-1)/2
They are as they were. That one key is JUST DELETED
Even this question is already answered I'd add the solution in Regex.
>>> import re
>>> file_suffix = ".*(\..*)"
>>> result = re.search(file_suffix, "somefile.ext")
>>> result.group(1)
'.ext'
I tried this code and it's working for me .
$html = file_get_contents('www.google.com');
$myVar = htmlspecialchars($html, ENT_QUOTES);
echo($myVar);
using System.Globalization;
DateTime d;
DateTime.TryParseExact(
"2010-08-20T15:00:00",
"s",
CultureInfo.InvariantCulture,
DateTimeStyles.AssumeUniversal, out d);
You can also use breakpoints. Assuming the value you want is defined within the scope of your breakpoint you have 3 options:
print it in console doing:
po some_paramter
Bare in mind in objective-c for properties you can't use self.
po _someProperty
po self.someProperty // would not work
po stands for print object.
Or can just use Xcode 'Variable Views' . See the image
I highly recommend seeing Debugging with Xcode from Apple
Or just hover over within your code. Like the image below.
Assuming two decimal places on your percentages, the data type you use depends on how you plan to store your percentages. If you are going to store their fractional equivalent (e.g. 100.00% stored as 1.0000), I would store the data in a decimal(5,4)
data type with a CHECK
constraint that ensures that the values never exceed 1.0000 (assuming that is the cap) and never go below 0 (assuming that is the floor). If you are going to store their face value (e.g. 100.00% is stored as 100.00), then you should use decimal(5,2)
with an appropriate CHECK
constraint. Combined with a good column name, it makes it clear to other developers what the data is and how the data is stored in the column.
The closest thing to renaming is deleting and then re-creating on the remote. For example:
git branch -m master master-old
git push remote :master # delete master
git push remote master-old # create master-old on remote
git checkout -b master some-ref # create a new local master
git push remote master # create master on remote
However this has a lot of caveats. First, no existing checkouts will know about the rename - git does not attempt to track branch renames. If the new master
doesn't exist yet, git pull will error out. If the new master
has been created. the pull will attempt to merge master
and master-old
. So it's generally a bad idea unless you have the cooperation of everyone who has checked out the repository previously.
Note: Newer versions of git will not allow you to delete the master branch remotely by default. You can override this by setting the receive.denyDeleteCurrent
configuration value to warn
or ignore
on the remote repository. Otherwise, if you're ready to create a new master right away, skip the git push remote :master
step, and pass --force
to the git push remote master
step. Note that if you're not able to change the remote's configuration, you won't be able to completely delete the master branch!
This caveat only applies to the current branch (usually the master
branch); any other branch can be deleted and recreated as above.
Very simple way, maybe too simple:
var cloned = JSON.parse(JSON.stringify(objectToClone));
This is a known bug at MySQL.
As you can see this has been a known issue since 2008 and they have not fixed it yet!!!
WORK AROUND
You first need to create the database to import. It doesn't need any tables. Then you can import your database.
first start your MySQL command line (apply username and password if you need to)
C:\>mysql -u user -p
Create your database and exit
mysql> DROP DATABASE database;
mysql> CREATE DATABASE database;
mysql> Exit
Import your selected database from the dump file
C:\>mysql -u user -p -h localhost -D database -o < dumpfile.sql
You can replace localhost with an IP or domain for any MySQL server you want to import to. The reason for the DROP command in the mysql prompt is to be sure we start with an empty and clean database.

If there is a reason you can't use the simple solution provided by ennuikiller above, then you will have to use Typeglobs to manipulate file handles. This is way more work. This example copies from the file in $ARGV[0]
to that in $ARGV[1]
. It defaults to STDIN
and STDOUT
respectively if files are not specified.
use English;
my $in;
my $out;
if ($#ARGV >= 0){
unless (open($in, "<", $ARGV[0])){
die "could not open $ARGV[0] for reading.";
}
}
else {
$in = *STDIN;
}
if ($#ARGV >= 1){
unless (open($out, ">", $ARGV[1])){
die "could not open $ARGV[1] for writing.";
}
}
else {
$out = *STDOUT;
}
while ($_ = <$in>){
$out->print($_);

You should use a shared preference to store the property and act upon it using service binding from your activities. If you use binding only, (that is never use startService), then your service would run only when you bind to it, (bind onResume and unbind onPause) that would make it run on foreground only, and if you do want to work on background you can use the regular start stop service.
It is cumbersome to interoperate socket.io and connect sessions support. The problem is not because socket.io "hijacks" request somehow, but because certain socket.io transports (I think flashsockets) don't support cookies. I could be wrong with cookies, but my approach is the following:
For dynamic pivot, use GROUP_CONCAT
with CONCAT
.
The GROUP_CONCAT function concatenates strings from a group into one string with various options.
SET @sql = NULL;
SELECT
GROUP_CONCAT(DISTINCT
CONCAT(
'SUM(CASE WHEN action = "',
action,'" AND ',
(CASE WHEN pagecount IS NOT NULL
THEN CONCAT("pagecount = ",pagecount)
ELSE pagecount IS NULL END),
' THEN 1 ELSE 0 end) AS ',
action, IFNULL(pagecount,'')
)
)
INTO @sql
FROM
t;
SET @sql = CONCAT('SELECT company_name, ', @sql, '
FROM t
GROUP BY company_name');
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
Instead of doing this via an SQL query use the php function: mysqli::set_charset mysqli_set_charset
Note: This is the preferred way to change the charset. Using mysqli_query() to set it (such as SET NAMES utf8) is not recommended.
See the MySQL character set concepts section for more information.
the correct way to do will be as following in the old-style classes which doesn't inherit from 'object'
class A:
def foo(self):
return "Hi there"
class B(A):
def foo(self, name):
return A.foo(self) + name
Yes, the Jackson manual parser design is quite different from other libraries. In particular, you will notice that JsonNode
has most of the functions that you would typically associate with array nodes from other API's. As such, you do not need to cast to an ArrayNode
to use. Here's an example:
JSON:
{
"objects" : ["One", "Two", "Three"]
}
Code:
final String json = "{\"objects\" : [\"One\", \"Two\", \"Three\"]}";
final JsonNode arrNode = new ObjectMapper().readTree(json).get("objects");
if (arrNode.isArray()) {
for (final JsonNode objNode : arrNode) {
System.out.println(objNode);
}
}
Output:
"One"
"Two"
"Three"
Note the use of isArray
to verify that the node is actually an array before iterating. The check is not necessary if you are absolutely confident in your datas structure, but its available should you need it (and this is no different from most other JSON libraries).
WAMP = Windows + Apache + MySQL/MariaDB + PHP/Python/Perl

These are class stereotypes used in analysis.
boundary classes are ones at the boundary of the system - the classes that you or other systems interact with
entity classes classes are your typical business entities like "person" and "bank account"

Set the contentHorizontalAlignment:
emailBtn.contentHorizontalAlignment = .left;
You might also want to adjust the content left inset otherwise the text will touch the left border:
emailBtn.contentEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);
// Swift 3 and up:
emailBtn.contentEdgeInsets = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 0);
the accepted answer is correct.. for mobile you can also use this (ng-touched rather ng-dirty)
input.ng-invalid.ng-touched{
border-bottom: 1px solid #e74c3c !important;
}
A "JSON object" doesn't make sense : JSON is an exchange format based on the structure of Javascript object declaration.
If you want to convert your javascript object to a json string, use JSON.stringify(yourObject)
;
If you want to create a javascript object, simply do it like this :
var yourObject = {
test:'test 1',
testData: [
{testName: 'do',testId:''}
],
testRcd:'value'
};
You can do date arithmetic by using NSDateComponents
. For example:
import Foundation
let comps = NSDateComponents()
comps.minute = 5
let cal = NSCalendar.currentCalendar()
let r = cal.dateByAddingComponents(comps, toDate: NSDate(), options: nil)
It is what you see when you try it in playground
Try this:
string callbackurl = Request.Url.Host != "localhost"
? Request.Url.Host : Request.Url.Authority;
This will work for local as well as production environment. Because the local uses url with port no that is possible using Url.Host.
For me, it was happen due to a miss configuration
Docker port (9093)
Kafka command port "bin/kafka-console-producer.sh --broker-list localhost:9092 --topic TopicName"
I checked my configuration to match port and now everything is ok
The java.util.Collections class has a sort method that takes a list and a custom Comparator. You can define your own Comparator to sort your Person object however you like.
Is there anything wrong with Nahuel Greco's solution aside from the compilation error?
If I change one line
// Compilation error
setsockopt(fd, SO_SNDTIMEO, &timeout, sizeof(timeout));
to
// Fixed?
setsockopt(fd, SOL_SOCKET, SO_SNDTIMEO, &timeout, sizeof(timeout));
then it seems to work as advertised - socket()
returns a timeout error.
Resulting code:
struct timeval timeout;
timeout.tv_sec = 7; // after 7 seconds connect() will timeout
timeout.tv_usec = 0;
setsockopt(fd, SOL_SOCKET, SO_SNDTIMEO, &timeout, sizeof(timeout));
connect(...)
I'm not versed enough to know the tradeoffs are between a send timeout and a non-blocking socket, but I'm curious to learn.
You can set a default value at creation time like:
CREATE TABLE Persons (
ID int NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
Married boolean DEFAULT false);
You probably won't be able to get it in a platform independent way. Windows you get number of processors.
If none of the other answers work for you then try the following which was the only thing that worked for me:
Find your .csproj
file and edit it in a text editor.
Find the <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
tag in your .csproj
file and delete the whole block.
Re-install all packages in the solution:
Update-Package -reinstall
After this your nuget packages should be restored, i think this might be a fringe case that only occurs when you move your project to a different location.
Though this question has been answered many times before, I thought I would add to it with a more complete and solid answer for future users. The main answer does solve the problem, but I believe it may be better to know/understand the some of various ways to show/hide things.
.
This is the way I used to do it until I found some of these other ways.
Javascript:
$("#element_to_hide").css("display", "none"); // To hide
$("#element_to_hide").css("display", ""); // To unhide
Pros:
Cons:
$("#element_to_hid").css("display", "inline");
otherwise it will default back to "block" or whatever else that it will be forced into.Example: https://jsfiddle.net/4chd6e5r/1/
.
While setting up the example for this one, I actually ran into some flaws on this method that make it very very unreliable.
Css/Javascript:
.hidden {display:none}
$("#element_to_hide").addClass("hidden"); // To hide
$("#element_to_hide").removeClass("hidden"); // To unhide
Pros:
$(".hidden")
.Cons:
Example: https://jsfiddle.net/476oha8t/8/
.
Javascript:
$("element_to_hide").toggle(); // To hide and to unhide
Pros:
Cons:
Example: https://jsfiddle.net/cxcawkyk/1/
.
Javascript:
$("#element_to_hide").hide(); // To hide
$("#element_to_hide").show(); // To show
Pros:
Cons:
Example: https://jsfiddle.net/k0ukhmfL/
.
Overall, I would say the best to be hide()/show() unless you specifically need it to be a toggle. I hope you found this information to be helpful.
You have two options,
-If you want the value:
Dim MyValue as Variant ' or string/date/long/...
MyValue = ThisWorkbook.Sheets(1).Range("A1").Value
-if you want the cell object:
Dim oCell as Range ' or object (but then you'll miss out on intellisense), and both can also contain more than one cell.
Set oCell = ThisWorkbook.Sheets(1).Range("A1")
Get key values from list of dictionaries in python?
Ex:
data =
[{'obj1':[{'cpu_percentage':'15%','ram':3,'memory_percentage':'66%'}]},
{'obj2': [{'cpu_percentage':'0','ram':4,'memory_percentage':'35%'}]}]
for d in data:
for key,value in d.items():
z ={key: {'cpu_percentage': d['cpu_percentage'],'memory_percentage': d['memory_percentage']} for d in value}
print(z)
Output:
{'obj1': {'cpu_percentage': '15%', 'memory_percentage': '66%'}}
{'obj2': {'cpu_percentage': '0', 'memory_percentage': '35%'}}
How about this one.
ArrayList<String> names = new ArrayList<String>();
Collections.addAll(names, "Ryan", "Julie", "Bob");
In your example you are comparing the string objects, not their content.
Your comparison should be :
if (s.equals("/quit"))
Or if s
string nullity doesn't mind / or you really don't like NPEs:
if ("/quit".equals(s))
Given
std::vector<Rule>& topPriorityRules;
The correct way to remove the first element of the referenced vector is
topPriorityRules.erase(topPriorityRules.begin());
which is exactly what you suggested.
Looks like i need to do iterator overloading.
There is no need to overload an iterator in order to erase first element of std::vector
.
P.S. Vector (dynamic array) is probably a wrong choice of data structure if you intend to erase from the front.
Copying and pasting i386\jvm.cfg
from a different PC will resolve the issue.
Try using something like this:
<link rel="image_src" href="http://yoursite.com/graphics/yourimage.jpg" /link>`
Seems to work just fine on Firefox as long as you use a full path to your image.
Trouble is it get vertically offset downward for some reason. Image is 200 x 200 as recommended somewhere I read.
Put your code inside the try catch block: i.e :
try{
if(in.available()!=0){
// ------
}
}catch(EOFException eof){
//
}catch(Exception e){
//
}
}
I see many people use subqueries or else window functions to do this, but I often do this kind of query without subqueries in the following way. It uses plain, standard SQL so it should work in any brand of RDBMS.
SELECT t1.*
FROM mytable t1
LEFT OUTER JOIN mytable t2
ON (t1.UserId = t2.UserId AND t1."Date" < t2."Date")
WHERE t2.UserId IS NULL;
In other words: fetch the row from t1
where no other row exists with the same UserId
and a greater Date.
(I put the identifier "Date" in delimiters because it's an SQL reserved word.)
In case if t1."Date" = t2."Date"
, doubling appears. Usually tables has auto_inc(seq)
key, e.g. id
.
To avoid doubling can be used follows:
SELECT t1.*
FROM mytable t1
LEFT OUTER JOIN mytable t2
ON t1.UserId = t2.UserId AND ((t1."Date" < t2."Date")
OR (t1."Date" = t2."Date" AND t1.id < t2.id))
WHERE t2.UserId IS NULL;
Re comment from @Farhan:
Here's a more detailed explanation:
An outer join attempts to join t1
with t2
. By default, all results of t1
are returned, and if there is a match in t2
, it is also returned. If there is no match in t2
for a given row of t1
, then the query still returns the row of t1
, and uses NULL
as a placeholder for all of t2
's columns. That's just how outer joins work in general.
The trick in this query is to design the join's matching condition such that t2
must match the same userid
, and a greater date
. The idea being if a row exists in t2
that has a greater date
, then the row in t1
it's compared against can't be the greatest date
for that userid
. But if there is no match -- i.e. if no row exists in t2
with a greater date
than the row in t1
-- we know that the row in t1
was the row with the greatest date
for the given userid
.
In those cases (when there's no match), the columns of t2
will be NULL
-- even the columns specified in the join condition. So that's why we use WHERE t2.UserId IS NULL
, because we're searching for the cases where no row was found with a greater date
for the given userid
.
If you're running Python 3.3 or better, you can use the clear()
method of list
, which is parallel to clear()
of dict
, set
, deque
and other mutable container types:
alist.clear() # removes all items from alist (equivalent to del alist[:])
As per the linked documentation page, the same can also be achieved with alist *= 0
.
To sum up, there are four equivalent ways to clear a list in-place (quite contrary to the Zen of Python!):
alist.clear() # Python 3.3+
del alist[:]
alist[:] = []
alist *= 0
To improve the Padraic's answer: when check_output
returns a non-zero code, it raises a CalledProcessError. This happens when the process does not exists or is not running.
What I would do to catch this exception is:
#!/usr/bin/python
from subprocess import check_output, CalledProcessError
def getPIDs(process):
try:
pidlist = map(int, check_output(["pidof", process]).split())
except CalledProcessError:
pidlist = []
print 'list of PIDs = ' + ', '.join(str(e) for e in pidlist)
if __name__ == '__main__':
getPIDs("chrome")
The output:
$ python pidproc.py
list of PIDS = 31840, 31841, 41942
Google guides me here but it didn't fix mine, this is a very general question and there are various causes, so I post my problem and solution here for reference in case anyone might read this later.
Another possible cause of 500 error is syntax error in header(...)
function, like this one:
header($_SERVER['SERVER_PROTOCOL'] . '200 OK');
Be aware there should be space between server protocol and status code, so it should be:
header($_SERVER['SERVER_PROTOCOL'] . ' 200 OK');
So I suggest check your http header call if you have it in your code.
The proper interval to get one second is 1000. The Interval
property is the time between ticks in milliseconds:
So, it's not the interval that you set that is wrong. Check the rest of your code for something like changing the interval of the timer, or binding the Tick
event multiple times.

If you previously issued a 301 redirect but want to un-do that
If people still have the cached 301 redirect in their browser they will continue to be taken to the target page regardless of whether the source page still has the redirect in place. Your options for fixing this include:
The simplest and best solution is to issue another 301 redirect back again.
The browser will realise it is being directed back to what it previously thought was a decommissioned URL, and this should cause it re-fetch that URL again to confirm that the old redirect isn't still there.
If you don't have control over the site where the previous redirect target went to, then you are outta luck. Try and beg the site owner to redirect back to you.
In fact, this means:
a.com 301 to b.com
delete a.com 's 301
add b.com 301 to a.com
Then it works.
you could change the innerHtml on an element
function produceMessage(){
var msg= 'Hello<br />';
document.getElementById('someElement').innerHTML = msg;
}
To summarize:
p 10.to_s(16) #=> "a"
p "%x" % 10 #=> "a"
p "%02X" % 10 #=> "0A"
p sprintf("%02X", 10) #=> "0A"
p "#%02X%02X%02X" % [255, 0, 10] #=> "#FF000A"
Assuming you have a byte string like so
"\x12\x45\x00\xAB"
and you know the amount of bytes and their type you can also use this approach
import struct
bytes = '\x12\x45\x00\xAB'
val = struct.unpack('<BBH', bytes)
#val = (18, 69, 43776)
As I specified little endian (using the '<' char) at the start of the format string the function returned the decimal equivalent.
0x12 = 18
0x45 = 69
0xAB00 = 43776
B is equal to one byte (8 bit) unsigned
H is equal to two bytes (16 bit) unsigned
More available characters and byte sizes can be found here
The advantages are..
You can specify more than one byte and the endian of the values
Disadvantages..
You really need to know the type and length of data your dealing with
The main difference between this answer and the accepted answer is the use of setViewportView()

How to put JTable
in JScrollPane
using Eclipse IDE:
JScrollPane
container via Design tab.JScrollPane
to desired size (applies to Absolute Layout).JTable
component on top of JScrollPane
(Viewport area).In Structure > Components, table
should be a child of scrollPane
.
The generated code would be something like this:
JScrollPane scrollPane = new JScrollPane();
...
JTable table = new JTable();
scrollPane.setViewportView(table);
The problem for me was as simple as just not knowing Javascript well. I was trying to pass the name of the id using double quotes, when I should have been using single. And it worked fine.
This worked:
validateSelectizeDropdown('#PartCondition')
This did not:
validateSelectizeDropdown("#PartCondition")
And the function:
function validateSelectizeDropdown(name) {
if ($(name).val() === "") {
//do something
}
}
I haven't personally checked, but hadoop-yarn-container-virtual-memory-understanding-and-solving-container-is-running-beyond-virtual-memory-limits-errors sounds very reasonable
I solved the issue by changing yarn.nodemanager.vmem-pmem-ratio
to a higher value , and I would agree that:
Another less recommended solution is to disable the virtual memory check by setting yarn.nodemanager.vmem-check-enabled to false.
Spring is three things.
The problem is that Spring DI is really well thought out, the wrappers around other things are really well thought out in that the other things thought everything out and Spring just nicely wraps it. The Spring implementations of MVC and REST and all the other stuff is not as well done (YMMV, IMHO) but there are exceptions (Spring Security is da bomb). So I tend to use Spring for DI, and its cool wrappers but prefer other stuff for Web (I like Tapestry a lot), REST (Jersey is really robust), etc.
You could use preg_split
instead of explode
and split on [ ]+
(one or more spaces). But I think in this case you could go with preg_match_all
and capturing:
preg_match_all('/[ ]php[ ]+\S+[ ]+(\S+)/', $input, $matches);
$result = $matches[1];
The pattern matches a space, php
, more spaces, a string of non-spaces (the path), more spaces, and then captures the next string of non-spaces. The first space is mostly to ensure that you don't match php
as part of a user name but really only as a command.
An alternative to capturing is the "keep" feature of PCRE. If you use \K
in the pattern, everything before it is discarded in the match:
preg_match_all('/[ ]php[ ]+\S+[ ]+\K\S+/', $input, $matches);
$result = $matches[0];
I would use preg_match()
. I do something similar for many of my system management scripts. Here is an example:
$test = "user 12052 0.2 0.1 137184 13056 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust1 cron
user 12054 0.2 0.1 137184 13064 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust3 cron
user 12055 0.6 0.1 137844 14220 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust4 cron

root 12070 0.0 0.0 103240 828 pts/1 R+ 10:00 0:00 grep utilities";
$lines = explode("\n", $test);
foreach($lines as $line){
if(preg_match("/.php[\s+](cust[\d]+)[\s+]cron/i", $line, $matches)){
print_r($matches);
}
}
The above prints:
Array
(
[0] => .php cust1 cron
[1] => cust1
)
Array
(
[0] => .php cust3 cron
[1] => cust3
)
Array
(
[0] => .php cust4 cron
[1] => cust4
)
Array
(
[0] => .php cust89 cron
[1] => cust89
)
Array
(
[0] => .php cust435 cron
[1] => cust435
)
Array
(
[0] => .php cust16 cron
[1] => cust16
)
You can set $test
to equal the output from exec. the values you are looking for would be in the if
statement under the foreach
. $matches[1]
will have the custx value.
I had the same problem while creating AVD with 4.2.2 images, I resolved it by doing the following :
Check if there exist a "default" folder in adt-bundle-windows-x86_64-20131030\sdk\system-images\android-17.
If it exists then move the contents(downloaded system images) of the "default" folder to adt-bundle-windows-x86_64-20131030\sdk\system-images\android-17.
Hope this helps.
In your model create the raw SQL statement (example below is an example of a date interval I had to use but substitute your own. If you are doing a SELECT add ->fetchall() to the execute() call.
$sql = "DELETE FROM tmp
WHERE lastedit + INTERVAL '5 minute' < NOW() ";
$stmt = $this->getServiceLocator()
->get('Doctrine\ORM\EntityManager')
->getConnection()
->prepare($sql);
$stmt->execute();
Do you know View.getViewTreeObserver().addOnGlobalLayoutListener()
By this you can calculate the sizes.
I achieve your UI effect by GridView:

I had this error for the first time ever while trying to debug some old legacy code, running now on PHP 7.30. The simplified code looked like this:
$testOK = true;
if ($testOK) {
$x['error'][] = 0;
$x['size'][] = 10;
$x['type'][] = 'file';
$x['tmp_name'][] = 'path/to/file/';
}
The simplest fix possible was to declare $x as array() before:
$x = array();
if ($testOK) {
// same code
}

To setup GruntJS build here is the steps:
Make sure you have setup your package.json
or setup new one:
npm init
Install Grunt CLI as global:
npm install -g grunt-cli
Install Grunt in your local project:
npm install grunt --save-dev
Install any Grunt Module you may need in your build process. Just for sake of this sample I will add Concat module for combining files together:
npm install grunt-contrib-concat --save-dev
Now you need to setup your Gruntfile.js
which will describe your build process. For this sample I just combine two JS files file1.js
and file2.js
in the js
folder and generate app.js
:
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
concat: {
"options": { "separator": ";" },
"build": {
"src": ["js/file1.js", "js/file2.js"],
"dest": "js/app.js"
}
}
});
// Load required modules
grunt.loadNpmTasks('grunt-contrib-concat');
// Task definitions
grunt.registerTask('default', ['concat']);
};
Now you'll be ready to run your build process by following command:
grunt
I hope this give you an idea how to work with GruntJS build.
NOTE:
You can use grunt-init
for creating Gruntfile.js
if you want wizard-based creation instead of raw coding for step 5.
To do so, please follow these steps:
npm install -g grunt-init
git clone https://github.com/gruntjs/grunt-init-gruntfile.git ~/.grunt-init/gruntfile
grunt-init gruntfile
For Windows users: If you are using cmd.exe you need to change ~/.grunt-init/gruntfile
to %USERPROFILE%\.grunt-init\
. PowerShell will recognize the ~
correctly.

Because it makes these things so easy, you could consider using a JavaScript library like jQuery to do this:
<script>
$(document).ready(function() {
$('img.thumbnail').click(function() {
window.location.href = this.id + '.html';
});
});
</script>
Basically, it attaches an onClick
event to all images with class thumbnail
to redirect to the corresponding HTML page (id
+ .html
). Then you only need the images in your HTML (without the a
elements), like this:
<img src="bottle.jpg" alt="bottle" class="thumbnail" id="bottle" />

For the most part Underscore.js is subset of Lodash.
At times, like presently, Underscore.js will have cool little functions Lodash doesn't have, like mapObject. This one saved me a lot of time in the development of my project.
You have to specify any one of the above phase to resolve the above error. In most of the situations, this would have occurred due to running the build from the eclipse environment.
instead of mvn clean package or mvn package you can try only package its work fine for me
Besides the other answers. You should notice these args can give you the file path that was dragged and dropped on the .exe
file.
i.e if you drag and drop any file on your .exe
file then the application will be launched and the arg[0]
will contain the file path that was dropped onto it.
static void Main(string[] args)
{
Console.WriteLine(args[0]);
}
this will print the path of the file dropped on the .exe
file. e.g
C:\Users\ABCXYZ\source\repos\ConsoleTest\ConsoleTest\bin\Debug\ConsoleTest.pdb
Hence, looping through the args
array will give you the path of all the files that were selected and dragged and dropped onto the .exe
file of your console app. See:
static void Main(string[] args)
{
foreach (var arg in args)
{
Console.WriteLine(arg);
}
Console.ReadLine();
}
The code sample above will print all the file names that were dragged and dropped onto it, See I am dragging 5 files onto my ConsoleTest.exe
app.
simply pass the argument
attachtoroot = false
View view = inflater.inflate(R.layout.child_layout_to_merge, parent_layout, false);
It is possible to disable ARC for individual files by adding the -fno-objc-arc
compiler flag for those files.
You add compiler flags in Targets -> Build Phases -> Compile Sources. You have to double click on the right column of the row under Compiler Flags. You can also add it to multiple files by holding the cmd button to select the files and then pressing enter to bring up the flag edit box. (Note that editing multiple files will overwrite any flags that it may already have.)
I created a sample project that has an example: https://github.com/jaminguy/NoArc
See this answer for more info: Disable Automatic Reference Counting for Some Files
You need to add a break statement:
switch (searchType)
{
case "SearchBooks":
Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
break;
case "SearchAuthors":
Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
break;
}
This assumes that you want to either handle the SearchBooks
case or the SearchAuthors
- as you had written in, in a traditional C-style switch statement the control flow would have "fallen through" from one case statement to the next meaning that all 4 lines of code get executed in the case where searchType == "SearchBooks"
.
The compiler error you are seeing was introduced (at least in part) to warn the programmer of this potential error.
As an alternative you could have thrown an error or returned from a method.
No, there isn't such constant.
I ran into the same error, when I just forgot to declare my custom component in my NgModule

The Entity Framework should not cause major bottlenecks itself. Chances are that there are other causes. You could try to switch EF to Linq2SQL, both have comparing features and the code should be easy to convert but in many cases Linq2SQL is faster than EF.
pip install pandas

In addition, to work with Xlsx files, you will need xlrd

You are testing if the values of the variables error
and Already
are present in RepoOutput[RepoName.index(repo)]
. If these variables don't exist then an undefined object is used.
Both of your if
and elif
tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].
I think you wanted to test if certain strings are in the value instead:
{% if "error" in RepoOutput[RepoName.index(repo)] %}
<td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
<td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
<td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>
Other corrections I made:
{% elif ... %}
instead of {$ elif ... %}
.</tr>
tag out of the if
conditional structure, it needs to be there always.id
attributeNote that most likely you want to use a class
attribute instead here, not an id
, the latter must have a value that must be unique across your HTML document.
Personally, I'd set the class value here and reduce the duplication a little:
{% if "Already" in RepoOutput[RepoName.index(repo)] %}
{% set row_class = "good" %}
{% else %}
{% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>

You will figure out that setOnPageChangeListener is deprecated, use addOnPageChangeListener, as below:
ViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
if(position == 1){ // if you want the second page, for example
//Your code here
}
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
Your IDs are #1
, and cycle
just wants a number passed to it. You need to remove the #
before calling cycle
.
$('a.pagerlink').click(function() {
var id = $(this).attr('id');
$container.cycle(id.replace('#', ''));
return false;
});
Also, IDs shouldn't contain the #
character, it's invalid (numeric IDs are also invalid). I suggest changing the ID to something like pager_1
.
<a href="#" id="pager_1" class="pagerlink" >link</a>
$('a.pagerlink').click(function() {
var id = $(this).attr('id');
$container.cycle(id.replace('pager_', ''));
return false;
});
I have used the following steps to resolve this problem
Kotlin version of this answer:
val intent = Intent(this, YourActivity::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK)
startActivity(intent)
Runtime.getRuntime().exit(0)
Sounds like you want to do something like this:
{{> person {another: 'attribute'} }}
Yehuda already gave you a way of doing that:
{{> person this}}
But to clarify:
To give your partial its own data, just give it its own model inside the existing model, like so:
{{> person this.childContext}}
In other words, if this is the model you're giving to your template:
var model = {
some : 'attribute'
}
Then add a new object to be given to the partial:
var model = {
some : 'attribute',
childContext : {
'another' : 'attribute' // this goes to the child partial
}
}
childContext
becomes the context of the partial like Yehuda said -- in that, it only sees the field another
, but it doesn't see (or care about the field some
). If you had id
in the top level model, and repeat id
again in the childContext, that'll work just fine as the partial only sees what's inside childContext
.
I use WAMP. One easy install wizard, tons of modules to for Apache and PHP preconfigured and easy to turn on and off to match your remote config.
You could use g++ --version
in combination with the GCC ABI docs to find out.
You can template a struct as well as a class. However you can't template a typedef. So template<typename T> struct array {...};
works, but template<typename T> typedef struct {...} array;
does not. Note that there is no need for the typedef trick in C++ (you can use structs without the struct
modifier just fine in C++).
What frameworks do you use?
We use a mix of the logging application block, and a custom logging helper that works around the .Net framework bits. The LAB is configured to output fairly extensive log files included seperate general trace files for service method entry/exit and specific error files for unexpected issues. The configuration includes date/time, thread, pId etc. for debug assistance as well as the full exception detail and stack (in the case of an unexpected exception).
The custom logging helper makes use of the Trace.Correlation and is particularly handy in the context of logging in WF. For example we have a state machine that invokes a series of sequential workflows. At each of these invoke activities we log the start (using StartLogicalOperation) and then at the end we stop the logical operation with a gereric return event handler.
This has proven useful a few times when attempting to debug failures in complex business sequences as it allows us to determine things like If/Else branch decisions etc. more quickly based on the activity execution sequence.
What log outputs do you use?
We use text files and XML files. Text files are configured through the app block but we've got XML outputs as well from our WF service. This enables us to capture the runtime events (persistence etc.) as well as generic business type exceptions. The text files are rolling logs that are rolled by day and size (I believe total size of 1MB is a rollover point).
What tools to you use for viewing the logs?
We are using Notepad and WCF Service Trace Viewer depending on which output group we're looking at. The WCF Service Trace Viewer is really really handy if you've got your output setup correctly and can make reading the output much simpler. That said, if I know roughly where the error is anyway - just reading a well annotated text file is good as well.
The logs are sent to a single directory which is then split into sub-dirs based on the source service. The root dir is exposed via a website which has it's access controlled by a support user group. This allows us to take a look at production logs without having to put in requests and go through lengthy red tape processes for production data.
For WPF:
YourButtonName.RaiseEvent(new RoutedEventArgs(System.Windows.Controls.Primitives.ButtonBase.ClickEvent));
May the following two functions show the difference:
function varTest() {
var x = 31;
if (true) {
var x = 71; // Same variable!
console.log(x); // 71
}
console.log(x); // 71
}
function letTest() {
let x = 31;
if (true) {
let x = 71; // Different variable
console.log(x); // 71
}
console.log(x); // 31
}
A tty
is a physical terminal-teletype port on a computer (usually a serial port).
The word teletype is a shorting of the telegraph typewriter, or teletypewriter device from the 1930s - itself an electromagnetic device which replaced the telegraph encoding machines of the 1830s and 1840s.
A pty
is a pseudo-teletype port provided by a computer Operating System Kernel to connect software programs emulating terminals, such as ssh, xterm, or screen.
A terminal is simply a computer's user interface that uses text for input and output.
These use pseudo-teletype ports however, their naming and implementations have diverged a little.
Linux mounts a special file system devpts on /dev (the 's' presumably standing for serial) that creates a corresponding entry in /dev/pts
for every new terminal window you open, e.g. /dev/pts/0
macOS/FreeBSD also use the /dev file structure however, they use a numbered TTY
naming convention ttys
for every new terminal window you open e.g. /dev/ttys002
Microsoft Windows still has the concept of an LPT
port for Line Printer Terminals within it's Command Shell for output to a printer.
The ALL_DIRECTORIES
data dictionary view will have information about all the directories that you have access to. That includes the operating system path
SELECT owner, directory_name, directory_path
FROM all_directories
The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:
Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();
This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.
Run cat -v file.sh
.
You most likely have a carriage return or no-break space in your file. cat -v
will show them as ^M
and M-BM-
or M-
respectively. It will similarly show any other strange characters you might have gotten into your file.
Remove the Windows line breaks with
tr -d '\r' < file.sh > fixedfile.sh
Try this
var s = {name: "raul", age: "22", gender: "Male"}
var keys = [];
for(var k in s) keys.push(k);
Here keys array will return your keys ["name", "age", "gender"]
There's no built-in way, you'll have to loop over all of them:
function setAll(a, v) {
var i, n = a.length;
for (i = 0; i < n; ++i) {
a[i] = v;
}
}
http://jsfiddle.net/alnitak/xG88A/
If you really want, do this:
Array.prototype.setAll = function(v) {
var i, n = this.length;
for (i = 0; i < n; ++i) {
this[i] = v;
}
};
and then you could actually do cool.setAll(42)
(see http://jsfiddle.net/alnitak/ee3hb/).
Some people frown upon extending the prototype of built-in types, though.
EDIT ES5 introduced a way to safely extend both Object.prototype
and Array.prototype
without breaking for ... in ...
enumeration:
Object.defineProperty(Array.prototype, 'setAll', {
value: function(v) {
...
}
});
EDIT 2 In ES6 draft there's also now Array.prototype.fill
, usage cool.fill(42)
Put your whole content in linear layout which is placed inside ScrollView
.
ScrollView
takes only one layout as its child.
isScrollContainer="true"
This property is used when your softkey in android pops up and still you want your view to scroll.
The simplest solution would be to use a sorted map like TreeMap instead of HashMap. If you do not have control over the map construction, then the minimal solution would be to construct a sorted set of keys. You don't really need a new map.
Set<String> sortedKeys = new TreeSet<String>();
sortedKeys.addAll(codes.keySet());
for(String key: sortedKeys){
println(key + ":" + codes.get(key));
}
There are no data-validation attributes on your input. Make sure you have generated it with a server side helper such as Html.TextBoxFor and that it is inside a form:
@using (Html.BeginForm())
{
...
@Html.TextBoxFor(x => x.AgreementNumber)
}
Also I don't know what the jquery.validate.inline.js
script is but if it somehow depends on the jquery.validate.js
plugin make sure that it is referenced after it.
In all cases look at your javascript console in the browser for potential errors or missing scripts.
In JDK11
the String
class has a lines()
method:
Returning a stream of lines extracted from this string, separated by line terminators.
Further, the documentation goes on to say:
A line terminator is one of the following: a line feed character "\n" (U+000A), a carriage return character "\r" (U+000D), or a carriage return followed immediately by a line feed "\r\n" (U+000D U+000A). A line is either a sequence of zero or more characters followed by a line terminator, or it is a sequence of one or more characters followed by the end of the string. A line does not include the line terminator.
With this one can simply do:
Stream<String> stream = str.lines();
then if you want an array:
String[] array = str.lines().toArray(String[]::new);
Given this method returns a Stream it upon up a lot of options for you as it enables one to write concise and declarative expression of possibly-parallel operations.
This is a simple way.
<div class="row">
<div class="col-md-6 mx-auto">
<p>My text</p>
</div>
</div>
The number 6 controls the width of the column.
Deleting this line fixes it, but the problem is the boostrap files are in bower_components
and not checked into source control.
So, every developer on the team will get the css file with the map reference when they pull the repo and do bower install
(which is part of using a new repo).
The file should not have the reference to a map that is not there.
The type attribute is used to define the MIME type within the HTML document. Depending on what DOCTYPE you use, the type value is required in order to validate the HTML document.
The language attribute lets the browser know what language you are using (Javascript vs. VBScript) but is not necessarily essential and, IIRC, has been deprecated.
can use
border-width:2px;
border-style:solid;
border-color:black;
or as shorthand
border: 2px solid black
Hej man, why are you using this ?
dir /s/b/o:gn > f.txt (wrong one)
Don't you know what is that 'g' in '/o' ??

You should be using this instead:
dir /s/b/o:n > f.txt (right one)
h1 { font-size: 150%; }
h2 { font-size: 120%; }
Tune as needed.
After running into the same issue - here're some of my thoughts:
As it affects only Chrome (other browsers work fine with VideoForEverybody solution) the solution I've used is:
for every mp4 file, create a Theora encoded mp4 file (example.mp4 -> example_c.mp4) apply following js:
if (window.chrome)
$("[type=video\\\/mp4]").each(function()
{
$(this).attr('src', $(this).attr('src').replace(".mp4", "_c.mp4"));
});
Unfortunately it's a bad Chrome hack, but hey, at least it works.
Source: user: eithedog
This also can help: chrome could play html5 mp4 video but html5test said chrome did not support mp4 video codec
Also check your version of crome here: html5test
Here is also the code to handle the result:
def foo (a):
x=a
y=a*2
return (x,y)
(x,y) = foo(50)
Best answer is to use the from dateutil import parser
.
usage:
from dateutil import parser
datetime_obj = parser.parse('2018-02-06T13:12:18.1278015Z')
print datetime_obj
# output: datetime.datetime(2018, 2, 6, 13, 12, 18, 127801, tzinfo=tzutc())
I need to do this trick, maybe because I use a custom HTML element. If I do not do this,
target
in onItemAmounterClick
won't have the scrollIntoView
method
.html
<div *ngFor"...">
<my-component #target (click)="clicked(target)"></my-component>
</div>
.ts
onItemAmounterClick(target){
target.__ngContext__[0].scrollIntoView({behavior: 'smooth'});
}
How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)
From RFC 2818 (Section 3.1):
If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.
[...]
In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.
Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).
If you're using keytool
, as of Java 7, keytool
has an option to include a Subject Alternative Name (see the table in the documentation for -ext
): you could use -ext san=dns:www.example.com
or -ext san=ip:10.0.0.1
.
EDIT:
You can request a SAN in OpenSSL by changing openssl.cnf
(it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF
environment variable).
Set the following options (find the appropriate sections within brackets first):
[req]
req_extensions = v3_req
[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com
There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html
Try this
let val = this.SurveysList.filter(xi => {
if (xi.id == parseInt(this.apiId ? '0' : this.apiId))
return xi.Description;
})
console.log('Description : ', val );
I think you will want to use ThreadSafeClientConnManager.
You can see how it works here: http://foo.jasonhudgins.com/2009/08/http-connection-reuse-in-android.html
Or in the AndroidHttpClient
which uses it internally.
I had a similar issue with the latest Git sources (2.12.2) built along with the latest sources of all its dependencies (Zlib, Bzip, cURL, PCRE, ReadLine, IDN2, iConv, Unistring, etc).
It turns out libreadline
was giving GnuPG problems:
$ gpg --version
gpg: symbol lookup error: /usr/local/lib/libreadline.so.7: undefined symbol: UP
And of course, trying to get useful information from Git with -vvv
failed, so the failure was a mystery.
To resolve the PGP failure due to ReadLine, follow the instructions at Can't update or use package manager -- gpg error:
In terminal:
ls /usr/local/lib
there was a bunch of readline libs in there (libreadline.so.BLAH-BLAH) so i:
su mkdir temp mv /usr/local/lib/libreadline* temp ldconfig
I got a solution!
When resetting root password at step 2), also change the auth plugin to mysql_native_password
:
use mysql;
update user set authentication_string=PASSWORD("") where User='root';
update user set plugin="mysql_native_password" where User='root'; # THIS LINE
flush privileges;
quit;
This allowed me to log in successfully!
sudo /etc/init.d/mysql stop # stop mysql service
sudo mysqld_safe --skip-grant-tables & # start mysql without password
# enter -> go
mysql -uroot # connect to mysql
use mysql; # use mysql table
update user set authentication_string=PASSWORD("") where User='root'; # update password to nothing
update user set plugin="mysql_native_password" where User='root'; # set password resolving to default mechanism for root user
flush privileges;
quit;

When you see a socket error, a community came with 2 possible solutions:
sudo mkdir -p /var/run/mysqld; sudo chown mysql /var/run/mysqld
sudo mysqld_safe --skip-grant-tables &
(thanks to @Cerin)
Or
mkdir -p /var/run/mysqld && chown mysql:mysql /var/run/mysqld
(thanks to @Peter Dvukhrechensky)
mysql -uroot # "-hlocalhost" is default
Can lead to "missing file" or slt error.
mysql -uroot -h127.0.0.1
Works better.

First loop
$v = $a[0];
$v = $a[1];
$v = $a[2];
$v = $a[3];
Yes! Current $v
= $a[3]
position.
Second loop
$a[3] = $v = $a[0], echo $v; // same as $a[3] and $a[0] == 'zero'
$a[3] = $v = $a[1], echo $v; // same as $a[3] and $a[1] == 'one'
$a[3] = $v = $a[2], echo $v; // same as $a[3] and $a[2] == 'two'
$a[3] = $v = $a[3], echo $v; // same as $a[3] and $a[3] == 'two'
because $a[3]
is assigned by before processing.
Based on the code I've used for finding multiple instances of a string within a larger string, your code would look like:
List<int> inst = new List<int>();
int index = 0;
while (index >=0)
{
index = source.IndexOf("extract\"(me,i-have lots. of]punctuation", index);
inst.Add(index);
index++;
}
In General a function to return string after substring is
function getStringAfterSubstring(parentString, substring) {_x000D_
return parentString.substring(parentString.indexOf(substring) + substring.length)_x000D_
}_x000D_
_x000D_
function getStringBeforeSubstring(parentString, substring) {_x000D_
return parentString.substring(0, parentString.indexOf(substring))_x000D_
}_x000D_
console.log(getStringAfterSubstring('abcxyz123uvw', '123'))_x000D_
console.log(getStringBeforeSubstring('abcxyz123uvw', '123'))
_x000D_

Node's crypto module API is still unstable.
As of version 4.0.0, the native Crypto module is not unstable anymore. From the official documentation:
Crypto
Stability: 2 - Stable
The API has proven satisfactory. Compatibility with the npm ecosystem is a high priority, and will not be broken unless absolutely necessary.
So, it should be considered safe to use the native implementation, without external dependencies.
For reference, the modules mentioned bellow were suggested as alternative solutions when the Crypto module was still unstable.
You could also use one of the modules sha1 or md5 which both do the job.
$ npm install sha1
and then
var sha1 = require('sha1');
var hash = sha1("my message");
console.log(hash); // 104ab42f1193c336aa2cf08a2c946d5c6fd0fcdb
or
$ npm install md5
and then
var md5 = require('md5');
var hash = md5("my message");
console.log(hash); // 8ba6c19dc1def5702ff5acbf2aeea5aa
(MD5 is insecure but often used by services like Gravatar.)
The API of these modules won't change!
In my case, I also had to set workbench.editor.showTabs
property to true (in addition to workbench.editor.enablePreview
)
I'm not sure how it got changed to false. Maybe, I've accidentally set it to false using some shortcut.
If your project uses docker-compose, here is an approach for backing up and restoring your volumes.
Basically you add db-backup
and db-restore
services to your docker-compose.yml file, and adapt it for the name of your volume. My volume is named dbdata
in this example.
version: "3"
services:
db:
image: percona:5.7
volumes:
- dbdata:/var/lib/mysql
db-backup:
image: alpine
tty: false
environment:
- TARGET=dbdata
volumes:
- ./backup:/backup
- dbdata:/volume
command: sh -c "tar -cjf /backup/$${TARGET}.tar.bz2 -C /volume ./"
db-restore:
image: alpine
environment:
- SOURCE=dbdata
volumes:
- ./backup:/backup
- dbdata:/volume
command: sh -c "rm -rf /volume/* /volume/..?* /volume/.[!.]* ; tar -C /volume/ -xjf /backup/$${SOURCE}.tar.bz2"
For data consistency, stop your db container before backing up or restoring
docker-compose stop db
To back up to the default destination (backup/dbdata.tar.bz2
):
docker-compose run --rm db-backup
Or, if you want to specify an alternate target name, do:
docker-compose run --rm -e TARGET=mybackup db-backup
To restore from backup/dbdata.tar.bz2
, do:
docker-compose run --rm db-restore
Or restore from a specific file using:
docker-compose run --rm -e SOURCE=mybackup db-restore
I adapted commands from https://loomchild.net/2017/03/26/backup-restore-docker-named-volumes/ to create this approach.
For some reason, import as suggested by Ricardo didnt work for me. I got it working with following statement:
<import resource="classpath*:/spring-config.xml" />
You could also set the timezone at the JVM level
Date date1 = new Date();
System.out.println(date1);
TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
// or pass in a command line arg: -Duser.timezone="UTC"
Date date2 = new Date();
System.out.println(date2);
output:
Thu Sep 05 10:11:12 EDT 2013
Thu Sep 05 14:11:12 UTC 2013
Your project is too large. You have too many methods. There can only be 65536 methods per application. see here https://code.google.com/p/android/issues/detail?id=7147#c6
It is standard matplotlib.pyplot:
...
import matplotlib.pyplot as plt
plt.ylim(10, 40)
Or simpler, as mwaskom comments below:
ax.set(ylim=(10, 40))
I resolve the problem. It's very simple . if do you checking care the problem may be because the auxiliar variable has whitespace. Why ? I don't know but yus must use the trim() method and will resolve the problem
Have not tested it yet, but the looks are better than the one Alex mentions.
The description at winginx.com/en/htaccess says:
About the htaccess to nginx converter
The service is to convert an Apache's .htaccess to nginx configuration instructions.
First of all, the service was thought as a mod_rewrite to nginx converter. However, it allows you to convert some other instructions that have reason to be ported from Apache to nginx.
Note server instructions (e.g. php_value, etc.) are ignored.
The converter does not check syntax, including regular expressions and logic errors.
Please, check the result manually before use.
var x = parseInt(455/10);
The parseInt() function parses a string and returns an integer.
The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.
If the radix parameter is omitted, JavaScript assumes the following:
If the string begins with "0x", the radix is 16 (hexadecimal) If the string begins with "0", the radix is 8 (octal). This feature is deprecated If the string begins with any other value, the radix is 10 (decimal)
This might help http://docs.pytest.org/en/latest/xunit_setup.html
In my test suite, I group my test cases into classes. For the setup and teardown I need for all the test cases in that class, I use the setup_class(cls)
and teardown_class(cls)
classmethods.
And for the setup and teardown I need for each of the test case, I use the setup_method(method)
and teardown_method(methods)
Example:
lh = <got log handler from logger module>
class TestClass:
@classmethod
def setup_class(cls):
lh.info("starting class: {} execution".format(cls.__name__))
@classmethod
def teardown_class(cls):
lh.info("starting class: {} execution".format(cls.__name__))
def setup_method(self, method):
lh.info("starting execution of tc: {}".format(method.__name__))
def teardown_method(self, method):
lh.info("starting execution of tc: {}".format(method.__name__))
def test_tc1(self):
<tc_content>
assert
def test_tc2(self):
<tc_content>
assert
Now when I run my tests, when the TestClass execution is starting, it logs the details for when it is beginning execution, when it is ending execution and same for the methods..
You can add up other setup and teardown steps you might have in the respective locations.
Hope it helps!
Let's say I have a remote named upstream and an origin (GitHub style, my fork is origin, upstream is upstream).
I don't want to delete ANY masters, HEAD, or anything from the upstream. I also don't want to delete the develop branch as that is our common branch we create PRs from.
List all remote branches, filtered by ones that were merged:
git branch -r
Remove lines from that list that contain words I know are in branch names I don't want to remove:
sed '/develop\|master\|HEAD\|upstream/d'
Remove the remote name from the reference name (origin/somebranch becomes somebranch):
sed 's/.*\///'
Use xargs to call a one-liner:
xargs git push --delete origin
Pipe it all together you get:
git branch -r --merged | sed '/develop\|master\|HEAD\|upstream/d' | sed 's/.*\///' | xargs git push --delete origin
This will leave me with only some branches that I have worked on, but have not merged. You can then remove them one by one as there shouldn't be too many.
Find branches you no longer want:
git branch -ar
Say you find branch1, branch2, and branch3 you want to delete:
git push --delete origin branch1 branch2 branch3
Use merge()
:
$request->merge([
'user_id' => $modified_user_id_here,
]);
Simple! No need to transfer the entire $request->all()
to another variable.
I wouldn't use checkboxes, i'd use the code you already have

The best approach from a performance perspective is probably to use a one or two arrays. Copy the list to an array, do operations on the array, and then build a new list from the array. Accessing an array element is faster than accessing a list item, and conversions between a List<T>
and a T[]
can use a fast "bulk copy" operation which avoids the overhead associated accessing individual items.
For example, suppose you have a List<string>
and wish to have every string in the list which starts with T
be followed by an item "Boo", while every string that starts with "U" is dropped entirely. An optimal approach would probably be something like:
int srcPtr,destPtr;
string[] arr;
srcPtr = theList.Count;
arr = new string[srcPtr*2];
theList.CopyTo(arr, theList.Count); // Copy into second half of the array
destPtr = 0;
for (; srcPtr < arr.Length; srcPtr++)
{
string st = arr[srcPtr];
char ch = (st ?? "!")[0]; // Get first character of string, or "!" if empty
if (ch != 'U')
arr[destPtr++] = st;
if (ch == 'T')
arr[destPtr++] = "Boo";
}
if (destPtr > arr.Length/2) // More than half of dest. array is used
{
theList = new List<String>(arr); // Adds extra elements
if (destPtr != arr.Length)
theList.RemoveRange(destPtr, arr.Length-destPtr); // Chop to proper length
}
else
{
Array.Resize(ref arr, destPtr);
theList = new List<String>(arr); // Adds extra elements
}
It would have been helpful if List<T>
provided a method to construct a list from a portion of an array, but I'm unaware of any efficient method for doing so. Still, operations on arrays are pretty fast. Of note is the fact that adding and removing items from the list does not require "pushing" around other items; each item gets written directly to its appropriate spot in the array.
Looking at your requirement, there is alternate solution as well. It seems you know the dimensions in dp at compile time, so you can add a dimen entry in the resources. Then you can query the dimen entry and it will be automatically converted to pixels in this call:
final float inPixels= mActivity.getResources().getDimension(R.dimen.dimen_entry_in_dp);
And your dimens.xml will have:
<dimen name="dimen_entry_in_dp">72dp</dimen>
Extending this idea, you can simply store the value of 1dp or 1sp as a dimen entry and query the value and use it as a multiplier. Using this approach you will insulate the code from the math stuff and rely on the library to perform the calculations.
Similar to Julien's answer above, I had success with the following:
fig, ax = plt.subplots(figsize=(10,4))
for key, grp in df.groupby(['ticker']):
ax.plot(grp['Date'], grp['adj_close'], label=key)
ax.legend()
plt.show()
This solution might be more relevant if you want more control in matlab.

You can't, Print Preview is a feature of a browser, and therefore should be protected from being called by JavaScript as it would be a security risk.
That's why your example uses Active X, which bypasses the JavaScript security issues.
So instead use the print stylesheet that you already should have and show it for media=screen,print instead of media=print.
Read Alist Apart: Going to Print for a good article on the subject of print stylesheets.
Change the following to the file
/usr/local/mysql/support-files/mysql.server
the follow lines:
basedir="/usr/local/mysql"

add the follow line at end:
/usr/local/mysql/bin/mysqld_safe --user=mysql &
You can try this:
@OneToOne(cascade = CascadeType.REFRESH)
or
@OneToMany(cascade = CascadeType.REFRESH)
You just forgot the quotes. Change your code according to this:
<button type="button" onClick = "document.getElementById('chartdiv').style.height = '200px'">Click Me!</button>
should work.
Just a quick check as well if you keep your js files separately: make sure to reload your resources properly. Browsers will usually cache files, so just assure that i.e. a former typo is corrected in your loaded resources.
See this answer for permanent cache disabling in Chrome/Chromium. Otherwise you can generally force a full reload with Ctrl+F5 or Shift+F5 as mentioned in this answer.
Once you have cloned the repo, you have everything: you can then hg up branchname
or hg up tagname
to update your working copy.
UP: hg up
is a shortcut of hg update
, which also has hg checkout
alias for people with git
habits.
The C5 Generic Collections Library classes all support the AddRange
method. C5 has a much more robust interface that actually exposes all of the features of its underlying implementations and is interface-compatible with the System.Collections.Generic
ICollection
and IList
interfaces, meaning that C5
's collections can be easily substituted as the underlying implementation.
I would say remove them and define a default: branch.
The difference between the commands is that one provides you with a tag message while the other doesn't. An annotated tag has a message that can be displayed with git-show(1), while a tag without annotations is just a named pointer to a commit.
According to the documentation: "To create a lightweight tag, don’t supply any of the -a, -s, or -m options, just provide a tag name". There are also some different options to write a message on annotated tags:
git tag <tagname>
, Git will create a tag at the current revision but will not prompt you for an annotation. It will be tagged without a message (this is a lightweight tag).git tag -a <tagname>
, Git will prompt you for an annotation unless you have also used the -m flag to provide a message.git tag -a -m <msg> <tagname>
, Git will tag the commit and annotate it with the provided message.git tag -m <msg> <tagname>
, Git will behave as if you passed the -a flag for annotation and use the provided message.Basically, it just amounts to whether you want the tag to have an annotation and some other information associated with it or not.
Happened to me when in windows, when using photoshop: When I saved an image and then switched to a branch (leaving photoshop with the image opened) i got the git error. Close the image in photoshop and retry
Using double
to store large integers is dubious; the largest integer that can be stored reliably in double
is much smaller than DBL_MAX
. You should use long long
, and if that's not enough, you need your own arbitrary-precision code or an existing library.
I'm disappointed at how long it took to work this out.
I want to see which values in my range are outside standard deviation.
=STDEV(L3:L32)*2
=$L$32
(whatever cell your stdev is in)I couldn't work out how to put the STDEv inline. I tried many things with unexpected results.
JavaScript code:
'option strict';
function largestPrimeFactor(val, divisor = 2) {
let square = (val) => Math.pow(val, 2);
while ((val % divisor) != 0 && square(divisor) <= val) {
divisor++;
}
return square(divisor) <= val
? largestPrimeFactor(val / divisor, divisor)
: val;
}
Usage Example:
let result = largestPrimeFactor(600851475143);
Not with a regular statement, no.
What you can do is wrap the functionality in a PL/pgsql function (or another language, but PL/pgsql seems to be the most appropriate for this), and then just call that function. That means it'll still be a single statement to your app.
In case this helps someone, for me, none of the above was sufficient. I still couldn't build, VS still couldn't find the references. The key was simply to close and reopen the solution after restoring the packages.
Here's the scenario (using Visual Studio 2012):
You open a Solution that has missing packages. The references show that VS can't find them. There are many ways to restore the missing packages, including
nuget restore
if you have the command line nuget installedBut no matter what the approach, those references will still be shown as missing. And when you build it will fail. Sigh. However if you close the solution and re-open it, now VS checks those nice <HintPath>
s again, finds that the packages are back where they belong, and all is well with the world.
Is Visual Studio still not seeing that you have the package? Still showing a reference that it can't resolve? Make sure that the version of package you restored is exactly the same as the <HintPath>
in your .csproj file. Even a minor bug fix number (e.g. 1.10.1 to 1.10.2) will cause the reference to fail. You can fix this either by directly editing your csproj xml, or else by removing the reference and making a new one pointing at the newly-restored version in the packages directory.
You could use a map function that allows multiple arguments, as does the fork of multiprocessing
found in pathos
.
>>> from pathos.multiprocessing import ProcessingPool as Pool
>>>
>>> def add_and_subtract(x,y):
... return x+y, x-y
...
>>> res = Pool().map(add_and_subtract, range(0,20,2), range(-5,5,1))
>>> res
[(-5, 5), (-2, 6), (1, 7), (4, 8), (7, 9), (10, 10), (13, 11), (16, 12), (19, 13), (22, 14)]
>>> Pool().map(add_and_subtract, *zip(*res))
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]
pathos
enables you to easily nest hierarchical parallel maps with multiple inputs, so we can extend our example to demonstrate that.
>>> from pathos.multiprocessing import ThreadingPool as TPool
>>>
>>> res = TPool().amap(add_and_subtract, *zip(*Pool().map(add_and_subtract, range(0,20,2), range(-5,5,1))))
>>> res.get()
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]
Even more fun, is to build a nested function that we can pass into the Pool.
This is possible because pathos
uses dill
, which can serialize almost anything in python.
>>> def build_fun_things(f, g):
... def do_fun_things(x, y):
... return f(x,y), g(x,y)
... return do_fun_things
...
>>> def add(x,y):
... return x+y
...
>>> def sub(x,y):
... return x-y
...
>>> neato = build_fun_things(add, sub)
>>>
>>> res = TPool().imap(neato, *zip(*Pool().map(neato, range(0,20,2), range(-5,5,1))))
>>> list(res)
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]
If you are not able to go outside of the standard library, however, you will have to do this another way. Your best bet in that case is to use multiprocessing.starmap
as seen here: Python multiprocessing pool.map for multiple arguments (noted by @Roberto in the comments on the OP's post)

If you are experiencing this problem when using Docker be sure to map the correct port numbers. If you map port 81:80 when running docker (or through docker-compose.yml), your nginx must listen on port 80 not 81, because docker does the mapping already.
I spent quite some time on this issue myself, so hope it can be to some help for future googlers.
primitive way:
public string ToBinary(int n)
{
if (n < 2) return n.ToString();
var divisor = n / 2;
var remainder = n % 2;
return ToBinary(divisor) + remainder;
}
An IDE which supports Android development is Processing for Android: http://wiki.processing.org/w/Android. Processing is its own language but it's easy to learn. Processing for Android requires the JDK and Android SDK to be installed but runs on its own. It runs on Linux, Mac OSX and Windows (on a side note: one can develop a desktop app in Processing and then compile it to target any of these operating systems). Its development is ongoing but it works. It's especially good for quickly sketching up an idea and running it on your Android phone (even if you plan to develop it further in another IDE).
There is an active support forum here: http://forum.processing.org/android-processing.

I find it useful to have a class, derived from threading.Thread
, to encapsulate my thread functionality. You simply provide your own main loop in an overridden version of run()
in this class. Calling start()
arranges for the object’s run()
method to be invoked in a separate thread.
Inside the main loop, periodically check whether a threading.Event
has been set. Such an event is thread-safe.
Inside this class, you have your own join()
method that sets the stop event object before calling the join()
method of the base class. It can optionally take a time value to pass to the base class's join()
method to ensure your thread is terminated in a short amount of time.
import threading
import time
class MyThread(threading.Thread):
def __init__(self, sleep_time=0.1):
self._stop_event = threading.Event()
self._sleep_time = sleep_time
"""call base class constructor"""
super().__init__()
def run(self):
"""main control loop"""
while not self._stop_event.isSet():
#do work
print("hi")
self._stop_event.wait(self._sleep_time)
def join(self, timeout=None):
"""set stop event and join within a given time period"""
self._stop_event.set()
super().join(timeout)
if __name__ == "__main__":
t = MyThread()
t.start()
time.sleep(5)
t.join(1) #wait 1s max
Having a small sleep inside the main loop before checking the threading.Event
is less CPU intensive than looping continuously. You can have a default sleep time (e.g. 0.1s), but you can also pass the value in the constructor.
Assuming you're dealing with Windows 7 x64 and something that was previously installed with some sort of an installer, you can open regedit and search the keys under
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
(which references 32-bit programs) for part of the name of the program, or
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
(if it actually was a 64-bit program).
If you find something that matches your program in one of those, the contents of UninstallString
in that key usually give you the exact command you are looking for (that you can run in a script).
If you don't find anything relevant in those registry locations, then it may have been "installed" by unzipping a file. Because you mentioned removing it by the Control Panel, I gather this likely isn't then case; if it's in the list of programs there, it should be in one of the registry keys I mentioned.
Then in a .bat script you can do
if exist "c:\program files\whatever\program.exe" (place UninstallString contents here)
if exist "c:\program files (x86)\whatever\program.exe" (place UninstallString contents here)

The correct way to use LOCK TABLES and UNLOCK TABLES with transactional tables, such as InnoDB tables, is to begin a transaction with SET autocommit = 0 (not START TRANSACTION) followed by LOCK TABLES, and to not call UNLOCK TABLES until you commit the transaction explicitly. For example, if you need to write to table t1 and read from table t2, you can do this:
SET autocommit=0;
LOCK TABLES t1 WRITE, t2 READ, ...;... do something with tables t1 and t2 here ...
COMMIT;
UNLOCK TABLES;
As mentioned you need to use obj.getTile()
But, in this case I think you are looking to use a Property.
public class Pin
{
private string title;
public Pin() { }
public setTitle(string title) {
this.title = title;
}
public String Title
{
get { return title; }
}
}
This will allow you to use
foreach (Pin obj in ClassListPin.pins)
{
string t = obj.Title;

Call To the following function with argument as you file path:
private String getFileContent(String targetFilePath){
File file = new File(targetFilePath);
try {
fileInputStream = new FileInputStream(file);
}
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
Log.e("",""+e.printStackTrace());
}
StringBuilder sb;
while(fileInputStream.available() > 0) {
if(null== sb) sb = new StringBuilder();
sb.append((char)fileInputStream.read());
}
String fileContent;
if(null!=sb){
fileContent= sb.toString();
// This is your fileContent in String.
}
try {
fileInputStream.close();
}
catch(Exception e){
// TODO Auto-generated catch block
Log.e("",""+e.printStackTrace());
}
return fileContent;
}
I think you want json_encode
, not json_decode
.
Here is an implementation of a delete cookie function with unicode support from Mozilla:
function removeItem(sKey, sPath, sDomain) {
document.cookie = encodeURIComponent(sKey) +
"=; expires=Thu, 01 Jan 1970 00:00:00 GMT" +
(sDomain ? "; domain=" + sDomain : "") +
(sPath ? "; path=" + sPath : "");
}
removeItem("cookieName");
If you use AngularJs, try $cookies.remove (underneath it uses a similar approach):
$cookies.remove('cookieName');
When writing queries with our server LIKE or INSTR (or CHARINDEX in T-SQL) takes too long, so we use LEFT like in the following structure:
select *
from little
left join big
on left( big.key, len(little.key) ) = little.key
I understand that might only work with varying endings to the query, unlike other suggestions with '%' + b + '%', but is enough and much faster if you only need b+'%'.
Another way to optimize it for speed (but not memory) is to create a column in "little" that is "len(little.key)" as "lenkey" and user that instead in the query above.
