While configure could find my Boost installation, CMake could not.
Locate FindBoost.cmake and look for LIBRARY_HINTS to see what sub-packages it is looking for. In my case it wanted the MPI and graph libraries.
# Compute component-specific hints.
set(_Boost_FIND_LIBRARY_HINTS_FOR_COMPONENT "")
if(${COMPONENT} STREQUAL "mpi" OR ${COMPONENT} STREQUAL "mpi_python" OR
${COMPONENT} STREQUAL "graph_parallel")
foreach(lib ${MPI_CXX_LIBRARIES} ${MPI_C_LIBRARIES})
if(IS_ABSOLUTE "${lib}")
get_filename_component(libdir "${lib}" PATH)
string(REPLACE "\\" "/" libdir "${libdir}")
list(APPEND _Boost_FIND_LIBRARY_HINTS_FOR_COMPONENT ${libdir})
endif()
endforeach()

apt-cache search ... I installed the dev packages since I was building code, and the dev package drags in all the dependencies. I'm not so sure that a standard Boost install needs Open MPI, but this is OK for now.
sudo apt-get install libboost-mpi-dev libboost-mpi-python-dev
sudo apt-get install libboost-graph-parallel-dev

The lookup time is slow because when you use mmap
to does not load content of array to memory when you invoke load
method. Data is lazy loaded when particular data is needed.
And this happens in lookup in your case. But second lookup won`t be so slow.
This is nice feature of mmap
when you have a big array you do not have to load whole data into memory.
To solve your can use joblib you can dump any object you want using joblib.dump
even two or more numpy arrays
, see the example
firstArray = np.arange(100)
secondArray = np.arange(50)
# I will put two arrays in dictionary and save to one file
my_dict = {'first' : firstArray, 'second' : secondArray}
joblib.dump(my_dict, 'file_name.dat')
Further to @RobG's pure / vanilla javascript answer, you can reset to the 'default' value with
selectElement.selectedIndex = null;
It seems -1 deselects all items, null selects the default item, and 0 or a positive number selects the corresponding index option.
Options in a select object are indexed in the order in which they are defined, starting with an index of 0.
OS level analysis:
Find where the DB is stored on disk:
grep datadir /etc/my.cnf
datadir=/var/lib/mysql
Check for most recent modifications
cd /var/lib/mysql/{db_name}
ls -lrt
Should work on all database types.
In Galileo and Helios Provisioning Platform were introduced, and non-update-site plugins now should be placed in "dropins" subfolder ("eclipse/dropins/plugin_name/features", "eclipse/dropins/plugin_name/plugins") instead of Eclipse's folder ("eclipse/features" and "eclipse/plugins").
Also for programming needs the best Eclipse is the latest Eclipse. It has too many bugs for now, and all the Eclipse team is now doing is fixing the bugs. There are very few interface enhancements since Europa. IMHO.
eval
is not an acceptable practice if your directory names can be generated by untrusted sources. See BashFAQ #48 for more on why eval
should not be used, and BashFAQ #50 for more on the root cause of this problem and its proper solutions, some of which are touched on below:
If you need to build up your commands over time, use arrays:
tar_cmd=( tar cv "$directory" )
split_cmd=( split -b 1024m - "$backup_file" )
encrypt_cmd=( openssl des3 -salt )
"${tar_cmd[@]}" | "${encrypt_cmd[@]}" | "${split_cmd[@]}"
Alternately, if this is just about defining your commands in one central place, use functions:
tar_cmd() { tar cv "$directory"; }
split_cmd() { split -b 1024m - "$backup_file"; }
encrypt_cmd() { openssl des3 -salt; }
tar_cmd | split_cmd | encrypt_cmd
The latest version of virtualenvwrapper is tested under Python3.2. Chances are good it will work with Python3.3 too.

I use a Cancel button to return to the referring url. In the View, try adding this:
@{
ViewBag.Title = "Page title";
Layout = "~/Views/Shared/_Layout.cshtml";
if (Request.UrlReferrer != null)
{
string returnURL = Request.UrlReferrer.ToString();
ViewBag.ReturnURL = returnURL;
}
}
Then you can set your buttons href like this:
<a href="@ViewBag.ReturnURL" class="btn btn-danger">Cancel</a>
Other than that, the update by Jason Enochs works great!
Consider using MutationObserver. These observers are designed to react to changes in the DOM, and as a performant replacement to Mutation Events.

div { margin: auto; }
This will center your div.
Div by itself is a blockelement. Therefor you need to define the style to the div how to behave.
Get-ChildItem $originalPath\* -Include @("*.gif", "*.jpg", "*.xls*", "*.doc*", "*.pdf*", "*.wav*", "*.ppt")
It would be just as convenient to simply convert your collection into a list whenever it updates. But if you are initializing, this will suffice:
for(String i : collectionlist){
arraylist.add(i);
whateverIntID = arraylist.indexOf(i);
}
Be open-minded.

I tried the following after having already ensured that my computer had the same version in all locations and that my projects were all pointing to the same reference path. I had also made sure that the binding of the old version was their and bound to the current version of dll that I had.
I work in an environment with a strict framework and the framework team often upset the versioning with the different dll's.
How I fixed this issue was to run the package manager console within visual studio (2013). From there I ran the following command:
update-package Newtonsoft.Json -reinstall
followed by
update-package Newtonsoft.Json
This went through and updated all of my config files and relevant project files. Forcing them all to the same version of the dll. Which was initially version 4.5 before updating again to get the latest.
Although the existing answers are valid approaches , they are antiquated . HttpClient is a modern interface for working with RESTful web services . Check the examples section of the page in the link , it has a very straightforward use case for an asynchronous HTTP GET .
using (var client = new System.Net.Http.HttpClient())
{
return await client.GetStringAsync("https://reqres.in/api/users/3"); //uri
}
Instead of explicitly defining the path to the interpreter as in /usr/bin/bash/
, by using the env command, the interpreter is searched for and launched from wherever it is first found. This has both upsides and downsides
You could create a CSS class for this and apply it to your columns. Since the gutter (spacing between columns) is controlled by padding in Bootstrap 3, adjust the padding accordingly:
.col {
padding-right:7px;
padding-left:7px;
}
Demo: http://bootply.com/93473
EDIT If you only want the spacing between columns you can select all cols except first and last like this..
.col:not(:first-child,:last-child) {
padding-right:7px;
padding-left:7px;
}
For Bootstrap 4 see: Remove gutter space for a specific div only

That is a binary operator in hibernate you should use

Have a look at 14.10. Expressions
I usually execute following command in cmd prompt to check if my program.exe is running or not:
tasklist | grep program
You need enctype="multipart/form-data"
otherwise you will load only the file name and not the data.
Quick and dirty technique:
static byte[] StreamToByteArray(Stream inputStream)
{
if (!inputStream.CanRead)
{
throw new ArgumentException();
}
// This is optional
if (inputStream.CanSeek)
{
inputStream.Seek(0, SeekOrigin.Begin);
}
byte[] output = new byte[inputStream.Length];
int bytesRead = inputStream.Read(output, 0, output.Length);
Debug.Assert(bytesRead == output.Length, "Bytes read from stream matches stream length");
return output;
}
Test:
static void Main(string[] args)
{
byte[] data;
string path = @"C:\Windows\System32\notepad.exe";
using (FileStream fs = File.Open(path, FileMode.Open, FileAccess.Read))
{
data = StreamToByteArray(fs);
}
Debug.Assert(data.Length > 0);
Debug.Assert(new FileInfo(path).Length == data.Length);
}
I would ask, why do you want to read a stream into a byte[], if you are wishing to copy the contents of a stream, may I suggest using MemoryStream and writing your input stream into a memory stream.
<form id="myform">
<input type="textbox" id="field"/>
<input type="button" value="submit">
</form>
<script>
$(function () {
$("#field").keyup(function (event) {
if (event.which === 13) {
document.myform.submit();
}
}
});
</script>
Here is yet another way which fits in one line but is not particularly elegant:
dt = datetime.datetime.fromordinal(datetime.date.today().toordinal())
I am using eclipse and I was stuck on not being able to read files because of a "file not found exception". What I did to solve this problem was I moved the file to the root of my project. Hope this helps.
You can also use Bash on Ubuntu on Windows
directly. E.g.,
bash -c "ssh -t user@computer 'cd /; sudo my-command'"
Per Martin Prikryl's comment below:
The -t enables terminal emulation. Whether you need the terminal emulation for sudo depends on configuration (and by default you do no need it, while many distributions override the default). On the contrary, many other commands need terminal emulation.
Multiply by 1.
result = 1. * a / b
or, using the float function
result = float(a) / b
It is safer and more flexible to load the assembly into its own AppDomain
first.
So instead of the answer given previously:
var asm = Assembly.LoadFile(@"C:\myDll.dll");
var type = asm.GetType("TestRunner");
var runnable = Activator.CreateInstance(type) as IRunnable;
if (runnable == null) throw new Exception("broke");
runnable.Run();
I would suggest the following (adapted from this answer to a related question):
var domain = AppDomain.CreateDomain("NewDomainName");
var t = typeof(TypeIWantToLoad);
var runnable = domain.CreateInstanceFromAndUnwrap(@"C:\myDll.dll", t.Name) as IRunnable;
if (runnable == null) throw new Exception("broke");
runnable.Run();
Now you can unload the assembly and have different security settings.
If you want even more flexibility and power for dynamic loading and unloading of assemblies, you should look at the Managed Add-ins Framework (i.e. the System.AddIn
namespace). For more information, see this article on Add-ins and Extensibility on MSDN.
I would use the following function. I don't like sprintf
; it doesn't do what I want!!
#define hexchar(x) ((((x)&0x0F)>9)?((x)+'A'-10):((x)+'0'))
typedef signed long long Int64;
// Special printf for numbers only
// See formatting information below.
//
// Print the number "n" in the given "base"
// using exactly "numDigits".
// Print +/- if signed flag "isSigned" is TRUE.
// Use the character specified in "padchar" to pad extra characters.
//
// Examples:
// sprintfNum(pszBuffer, 6, 10, 6, TRUE, ' ', 1234); --> " +1234"
// sprintfNum(pszBuffer, 6, 10, 6, FALSE, '0', 1234); --> "001234"
// sprintfNum(pszBuffer, 6, 16, 6, FALSE, '.', 0x5AA5); --> "..5AA5"
void sprintfNum(char *pszBuffer, int size, char base, char numDigits, char isSigned, char padchar, Int64 n)
{
char *ptr = pszBuffer;
if (!pszBuffer)
{
return;
}
char *p, buf[32];
unsigned long long x;
unsigned char count;
// Prepare negative number
if (isSigned && (n < 0))
{
x = -n;
}
else
{
x = n;
}
// Set up small string buffer
count = (numDigits-1) - (isSigned?1:0);
p = buf + sizeof (buf);
*--p = '\0';
// Force calculation of first digit
// (to prevent zero from not printing at all!!!)
*--p = (char)hexchar(x%base);
x = x / base;
// Calculate remaining digits
while(count--)
{
if(x != 0)
{
// Calculate next digit
*--p = (char)hexchar(x%base);
x /= base;
}
else
{
// No more digits left, pad out to desired length
*--p = padchar;
}
}
// Apply signed notation if requested
if (isSigned)
{
if (n < 0)
{
*--p = '-';
}
else if (n > 0)
{
*--p = '+';
}
else
{
*--p = ' ';
}
}
// Print the string right-justified
count = numDigits;
while (count--)
{
*ptr++ = *p++;
}
return;
}

The location of the sitemap affects which URLs that it can include, but otherwise there is no standard. Here is a good link with more explaination: http://www.sitemaps.org/protocol.html#location
Some time, While executing insert query, we are facing:
Column not allowed here
error. Because of quote might missing in the string parameters. Add quote in the string params and try to execute.

Simply replace message parameter passed in clientSocket.sendto(message,(serverName, serverPort))
to clientSocket.sendto(message.encode(),(serverName, serverPort))
. Then you would successfully run in in python3
These will also redirect both:

yourcommand >& /dev/null
though the bash manual says the first is preferred.
You should only need to unbind the service in onDestroy()
. Then, The warning will go.
See here.
As the Activity doc tries to explain, there are three main bind/unbind groupings you will use: onCreate() and onDestroy(), onStart() and onStop(), and onResume() and onPause().
I would recommend looking at this article on how to use javascript to handle basic formatting:
function addCommas(nStr)
{
nStr += '';
x = nStr.split('.');
x1 = x[0];
x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, '$1' + ',' + '$2');
}
return x1 + x2;
}

While jQuery can make your life easier in a million different ways I would say it's overkill for this. Keep in mind that jQuery can be fairly large and your user's browser needs to download it when you use it on a page.
When ever using jQuery you should step back and ask if it contributes enough to justify the extra overhead of downloading the library.
If you need some sort of advanced formatting (like the localization stuff in the plugin you linked), or you are already including jQuery it might be worth looking at a jQuery plugin.
Side note - check this out if you want to get a chuckle about the over use of jQuery.
In DOS you couldn't use environment variables on the command line, only in batch files, where they used the %
sign as a delimiter. If you wanted a literal %
sign in a batch file, e.g. in an echo
statement, you needed to double it.
This carried over to Windows NT which allowed environment variables on the command line, however for backwards compatibility you still need to double your %
signs in a .cmd file.

If U want commit to a new empty Repo ,You can checkout the new empty Repo and commit to new remote repo.
chekout a new empty Repo won't delete your local files.
try this:
for example,
remote repo url : https://example.com/SVNTest
cd [YOUR PROJECT PATH]
rm -rf .svn
svn co https://example.com/SVNTest ../[YOUR PROJECT DIR NAME]
svn add ./*
svn ci -m"changed repo url"
If using g++
, make sure that you are not running gcc
instead
you can always use new stdClass()
. Example code:
$object = new stdClass();
$object->property = 'Here we go';
var_dump($object);
/*
outputs:
object(stdClass)#2 (1) {
["property"]=>
string(10) "Here we go"
}
*/
Also as of PHP 5.4 you can get same output with:
$object = (object) ['property' => 'Here we go'];
Here is a simplistic example of streaming a file:
using System.IO;
using Microsoft.AspNetCore.Mvc;
[HttpGet("{id}")]
public async Task<FileStreamResult> Download(int id)
{
var path = "<Get the file path using the ID>";
var stream = File.OpenRead(path);
return new FileStreamResult(stream, "application/octet-stream");
}
Note:
Be sure to use FileStreamResult
from Microsoft.AspNetCore.Mvc
and not from System.Web.Mvc
.
There's an ELSE in the DOS batch language? Back in the days when I did more of this kinda thing, there wasn't.
If my theory is correct and your ELSE is being ignored, you may be better off doing
IF NOT EXIST file GOTO label
...which will also save you a line of code (the one right after your IF).
Second, I vaguely remember some kind of bug with testing for the existence of directories. Life would be easier if you could test for the existence of a file in that directory. If there's no file you can be sure of, something to try (this used to work up to Win95, IIRC) would be to append the device file name NUL
to your directory name, e.g.
IF NOT EXIST C:\dir\NUL GOTO ...
If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".
Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".
It is a very murky distinction, and in fact generally not a property of a language itself, but rather of the program you are using to execute code in that language.
However, most languages are used primarily in one form or the other, and yes, Java is essentially always compiled, while javascript is essentially always interpreted.
To compile source code is to run a program on it that generates a binary, executable file that, when run, has the behavior defined by the source. For instance, javac compiles human-readbale .java files into machine-readable .class files.
To interpret source code is run a program on it that produces the defined behavior right away, without generating an intermediary file. For instance, when your web browser loads stackoverflow.com, it interprets a bunch of javascript (which you can look at by viewing the page source) and produces lots of the nice effects these pages have - for instance, upvoting, or the little notifier bars across the top.
You can use the start (^
) and end ($
) of line indicators:
^[0-9]{2}$
Some language also have functions that allows you to match against an entire string, where-as you were using a find
function. Matching against the entire string will make your regex work as an alternative to the above. The above regex will also work, but the ^
and $
will be redundant.
In WPF, it's pretty easy:
Assuming you've given the TabItem a name, e.g.,
<TabItem Header="Admin" Name="adminTab" Visibility="Hidden">
<!-- tab content -->
</TabItem>
You could have the following in the code behind the form:
if (user.AccessLevel == AccessLevelEnum.Admin)
{
adminTab.Visibility = System.Windows.Visibility.Visible;
}
It should be noted that a User
object named user
has been created with it's AccessLevel
property set to one of the user-defined enum values of AccessLevelEnum
... whatever; it's just a condition by which I decide to show the tab or not.
Try this:
onclick="javascript:location.href='http://www.uol.com.br/'"

To make angular ui $modal work with bootstrap 3 you need to overwrite the styles
.modal {
display: block;

.modal-body:before,
.modal-body:after {
display: table;
content: " ";
}
.modal-header:before,
.modal-header:after {
display: table;
content: " ";
}
(The last ones are necessary if you use custom directives) and encapsulate the html with
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>

I added some color to a GitHub markup page using emoji Enicode chars, e.g. or -- some emoji characters are colored in some browsers.
There are also some colored emoji alphabets: blood types ???; parking sign ?; Metro sign ??; a few others with two or more letters, such as , and boxed digits such as 0??. Flag emojis will show as letters (often colored) if the flag is not available: .
However, I don't think there is a complete colored alphabet defined in emoji.

In my case, Android Studio 3.0.1, I fixed the issue with the following two steps.
Step 1: Change Gradle plugin version in project-level build.gradle
buildscript {
repositories {
jcenter()
mavenCentral()
maven {
url 'https://maven.google.com/'
name 'Google'
}
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
}
}
Step 2: Change gradle version
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
You can also query the INFORMATION_SCHEMA.SCHEMATA view:
SELECT SCHEMA_NAME FROM INFORMATION_SCHEMA.SCHEMATA
I believe querying the INFORMATION_SCHEMA views is recommended as they protect you from changes to the underlying sys tables. From the SQL Server 2008 R2 Help:
Information schema views provide an internal, system table-independent view of the SQL Server metadata. Information schema views enable applications to work correctly although significant changes have been made to the underlying system tables. The information schema views included in SQL Server comply with the ISO standard definition for the INFORMATION_SCHEMA.
Ironically, this is immediately preceded by this note:
Some changes have been made to the information schema views that break backward compatibility. These changes are described in the topics for the specific views.
Ran into the same problem, I'm using maven so I added this to the pom in my web project:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version> <!-- just used the latest version, make sure you use the one you need -->
<scope>provided</scope>
</dependency>
This fixed the problem and I used "provided" scope because like the OP, everything was already working in JBoss.
Here's where I found the solution: http://alfredjava.wordpress.com/2008/12/22/jstl-connot-resolved/
In Python, curly braces are used to define a dictionary.
a={'one':1, 'two':2, 'three':3}
a['one']=1
a['three']=3
In other languages, { } are used as part of the flow control. Python however used indentation as its flow control because of its focus on readable code.
for entry in entries:
code....
There's a little easter egg in Python when it comes to braces. Try running this on the Python Shell and enjoy.
from __future__ import braces
Fail module works great! Thanks.
I had to define my fact before checking it, otherwise I'd get an undefined variable error.
And I had issues when doing setting the fact with quotes and without spaces.
This worked:
set_fact: flag="failed"
This threw errors:
set_fact: flag = failed
Here it is a solution using map function:
>>> a = [3, 7, 19]
>>> map(lambda x: (x, a[x]), range(len(a)))
[(0, 3), (1, 7), (2, 19)]
And a solution using list comprehensions:
>>> a = [3,7,19]
>>> [(x, a[x]) for x in range(len(a))]
[(0, 3), (1, 7), (2, 19)]
Static libraries do not link with other static libraries. The only way to do this is to use your librarian/archiver tool (for example ar on Linux) to create a single new static library by concatenating the multiple libraries.
Edit: In response to your update, the only way I know to select only the symbols that are required is to manually create the library from the subset of the .o files that contain them. This is difficult, time consuming and error prone. I'm not aware of any tools to help do this (not to say they don't exist), but it would make quite an interesting project to produce one.
Show Processlist fetches the information from another table. Here is how you can pull the data and look at 'INFO' column which contains the whole query :
select * from INFORMATION_SCHEMA.PROCESSLIST where db = 'somedb';
You can add any condition or ignore based on your requirement.
The output of the query is resulted as :
+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
| ID | USER | HOST | DB | COMMAND | TIME | STATE | INFO |
+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
| 5 | ssss | localhost:41060 | somedb | Sleep | 3 | | NULL |
| 58169 | root | localhost | somedb | Query | 0 | executing | select * from sometable where tblColumnName = 'someName' |
For a virtual function you need to provide implementation in the base class. However derived class can override this implementation with its own implementation. Normally , for pure virtual functions implementation is not provided. You can make a function pure virtual with =0
at the end of function declaration. Also, a class containing a pure virtual function is abstract i.e. you can not create a object of this class.
to clone git repo into the current and empty folder (no git init
) and if you do not use ssh:
git clone https://github.com/accountName/repoName.git .
if you want to add new text before or after the selected colum:
INSERT INTO atable (x,y,z) VALUES ( NULL,NULL,NULL)
What this means is that you are trying to print out/output a value which is at least partially uninitialized. Can you narrow it down so that you know exactly what value that is? After that, trace through your code to see where it is being initialized. Chances are, you will see that it is not being fully initialized.
If you need more help, posting the relevant sections of source code might allow someone to offer more guidance.
EDIT
I see you've found the problem. Note that valgrind watches for Conditional jump or move based on unitialized variables. What that means is that it will only give out a warning if the execution of the program is altered due to the uninitialized value (ie. the program takes a different branch in an if statement, for example). Since the actual arithmetic did not involve a conditional jump or move, valgrind did not warn you of that. Instead, it propagated the "uninitialized" status to the result of the statement that used it.
It may seem counterintuitive that it does not warn you immediately, but as mark4o pointed out, it does this because uninitialized values get used in C all the time (examples: padding in structures, the realloc()
call, etc.) so those warnings would not be very useful due to the false positive frequency.

You can use CSS Grid Layout. Support is rather wide at the moment: check it on caniuse.
Here is the example on jsfiddle. Also example with tons of text stuff.
HTML code:
<div class="container">
<div class="header">
Header
</div>
<div class="content">
Content
</div>
<div class="footer">
Footer
</div>
</div>
CSS Code:
html, body {
width: 100%;
height: 100%;
margin: 0;
}
.container {
width: 100%;
height: 100%;
display: grid;
grid-template-rows: 100px auto 150px;
grid-template-columns: auto;
}
// style stuff
From performance point of view if two lists contain number of elements that differ significantly, you can try such approach (using conditional operator ?:):
1.First you need to declare a converter:
Converter<string, int> del = delegate(string s) { return Int32.Parse(s); };
2.Then you use a conditional operator:
var r = data1.Count > data2.Count ?
data2.ConvertAll<int>(del).Intersect(data1) :
data1.Select(v => v.ToString()).Intersect(data2).ToList<string>().ConvertAll<int>(del);
You convert elements of shorter list to match the type of longer list. Imagine an execution speed if your first set contains 1000 elements and second only 10 (or opposite as it doesn't matter) ;-)
As you want to have a result as List, in a last line you convert the result (only result) back to int.
@vnr you can retrieve all the sort keys associated with a partition key by just using the query using partion key. No need of scan. The point here is partition key is compulsory in a query . Sort key are used only to get range of data
I know this is an older thread but I wanted to give what I think to be helpful information.
I personally use PyPy which is really easy to install using pip. I interchangeably use Python/PyPy interpreter, you don't need to change your code at all and I've found it to be roughly 40x faster than the standard python interpreter (Either Python 2x or 3x). I use pyCharm Community Edition to manage my code and I love it.
I like writing code in python as I think it lets you focus more on the task than the language, which is a huge plus for me. And if you need it to be even faster, you can always compile to a binary for Windows, Linux, or Mac (not straight forward but possible with other tools). From my experience, I get about 3.5x speedup over PyPy when compiling, meaning 140x faster than python. PyPy is available for Python 3x and 2x code and again if you use an IDE like PyCharm you can interchange between say PyPy, Cython, and Python very easily (takes a little of initial learning and setup though).
Some people may argue with me on this one, but I find PyPy to be faster than Cython. But they're both great choices though.
Edit: I'd like to make another quick note about compiling: when you compile, the resulting binary is much bigger than your python script as it builds all dependencies into it, etc. But then you get a few distinct benefits: speed!, now the app will work on any machine (depending on which OS you compiled for, if not all. lol) without Python or libraries, it also obfuscates your code and is technically 'production' ready (to a degree). Some compilers also generate C code, which I haven't really looked at or seen if it's useful or just gibberish. Good luck.
Hope that helps.

I initially avoided turning on logging to monitor PDO because I thought that it would be a hassle but it is not hard at all. You don't need to reboot MySQL (after 5.1.9):
Execute this SQL in phpMyAdmin or any other environment where you may have high db privileges:
SET GLOBAL general_log = 'ON';
In a terminal, tail your log file. Mine was here:
>sudo tail -f /usr/local/mysql/data/myMacComputerName.log
You can search for your mysql files with this terminal command:
>ps auxww|grep [m]ysqld
I found that PDO escapes everything, so you can't write
$dynamicField = 'userName';
$sql = "SELECT * FROM `example` WHERE `:field` = :value";
$this->statement = $this->db->prepare($sql);
$this->statement->bindValue(':field', $dynamicField);
$this->statement->bindValue(':value', 'mick');
$this->statement->execute();
Because it creates:
SELECT * FROM `example` WHERE `'userName'` = 'mick' ;
Which did not create an error, just an empty result. Instead I needed to use
$sql = "SELECT * FROM `example` WHERE `$dynamicField` = :value";
to get
SELECT * FROM `example` WHERE `userName` = 'mick' ;
When you are done execute:
SET GLOBAL general_log = 'OFF';
or else your logs will get huge.
You can use ObjectDataProvider
class and it's MethodName
property. It can look like this:
<Window.Resources>
<ObjectDataProvider x:Key="versionManager" ObjectType="{x:Type VersionManager}" MethodName="get_FilterString"></ObjectDataProvider>
</Window.Resources>
Declared object data provider can be used like this:
<TextBox Text="{Binding Source={StaticResource versionManager}}" />
Without jQuery:
var hasclass=!!(' '+elem.className+' ').indexOf(' check_class ')+1;
Or:
function hasClass(e,c){
return e&&(e instanceof HTMLElement)&&!!((' '+e.className+' ').indexOf(' '+c+' ')+1);
}
/*example of usage*/
var has_class_medium=hasClass(document.getElementsByTagName('input')[0],'medium');
This is WAY faster than jQuery!
If you installed OpenSSL on Windows together with Git, then add this to your command:
-config "C:\Program Files\Git\usr\ssl\openssl.cnf"
If you want to check if any item in the list violates a condition use all
:
if all([x[2] == 0 for x in lista]):
# Will run if all elements in the list has x[2] = 0 (use not to invert if necessary)
To remove all elements not matching, use filter
# Will remove all elements where x[2] is 0
listb = filter(lambda x: x[2] != 0, listb)
You are looking for the command scandir.
$path = '/tmp';
$files = scandir($path);
Following code will remove .
and ..
from the returned array from scandir
:
$files = array_diff(scandir($path), array('.', '..'));
If your keyboard is set to English US (International) rather than English US the double quotation marks don't work. This is why the single quotation marks worked in your case.
import java.util.Arrays;
public class ArrayDemo {
public static void main(String[] args) {
// initializing three object arrays
Object[] array1 = new Object[] { 1, 123 };
Object[] array2 = new Object[] { 1, 123, 22, 4 };
Object[] array3 = new Object[] { 1, 123 };
// comparing array1 and array2
boolean retval=Arrays.equals(array1, array2);
System.out.println("array1 and array2 equal: " + retval);
System.out.println("array1 and array2 equal: " + array1.equals(array2));
// comparing array1 and array3
boolean retval2=Arrays.equals(array1, array3);
System.out.println("array1 and array3 equal: " + retval2);
System.out.println("array1 and array3 equal: " + array1.equals(array3));
}
}
Here is the output:
array1 and array2 equal: false
array1 and array2 equal: false
array1 and array3 equal: true
array1 and array3 equal: false
Seeing this kind of problem I would personally go for Arrays.equals(array1, array2)
as per your question to avoid confusion.
Try Like this.
For Inserting into DB
$db = mysqli_connect("localhost","root","","DbName"); //keep your db name
$image = addslashes(file_get_contents($_FILES['images']['tmp_name']));
//you keep your column name setting for insertion. I keep image type Blob.
$query = "INSERT INTO products (id,image) VALUES('','$image')";
$qry = mysqli_query($db, $query);
For Accessing image From Blob
$db = mysqli_connect("localhost","root","","DbName"); //keep your db name
$sql = "SELECT * FROM products WHERE id = $id";
$sth = $db->query($sql);
$result=mysqli_fetch_array($sth);
echo '<img src="data:image/jpeg;base64,'.base64_encode( $result['image'] ).'"/>';
Hope It will help you.
Thanks.
One possible reason for this error is that your delimiter character (comma, semi-colon, pipe, whatever) actually appears in the data in one column. This can give very misleading error messages, often with the name of a totally different column.
One way to check this is to redirect the 'bad' rows to a separate file and then inspect them manually. Here's a brief explanation of how to do that:
http://redmondmag.com/articles/2010/04/12/log-error-rows-ssis.aspx
If that is indeed your problem, then the best solution is to fix the files at the source to quote the data values and/or use a different delimeter that isn't in the data.
You can do it as follow:
#include < iostream >
using namespace std;
int main () {
string texts[] = {"Apple", "Banana", "Orange"};
for( unsigned int a = 0; a < sizeof(texts) / 32; a++ ) { // 32 is the size of string data type
cout << "value of a: " << texts[a] << endl;
}
return 0;
}
what am I missing if empty array... keyless object... falseness const isEmpty = o => Array.isArray(o) && !o.join('').length || typeof o === 'object' && !Object.keys(o).length || !(+value);
I got a simpler solution which worked perfectly for me :
Drawable drawable = ContextCompat.getDrawable(getApplicationContext(),R.drawable.change_pass);
toolbar.setOverflowIcon(drawable);
Use to_datetime
, there is no need for a format string the parser is man/woman enough to handle it:
In [51]:
pd.to_datetime(df['I_DATE'])
Out[51]:
0 2012-03-28 14:15:00
1 2012-03-28 14:17:28
2 2012-03-28 14:50:50
Name: I_DATE, dtype: datetime64[ns]
To access the date/day/time component use the dt
accessor:
In [54]:
df['I_DATE'].dt.date
Out[54]:
0 2012-03-28
1 2012-03-28
2 2012-03-28
dtype: object
In [56]:
df['I_DATE'].dt.time
Out[56]:
0 14:15:00
1 14:17:28
2 14:50:50
dtype: object
You can use strings to filter as an example:
In [59]:
df = pd.DataFrame({'date':pd.date_range(start = dt.datetime(2015,1,1), end = dt.datetime.now())})
df[(df['date'] > '2015-02-04') & (df['date'] < '2015-02-10')]
Out[59]:
date
35 2015-02-05
36 2015-02-06
37 2015-02-07
38 2015-02-08
39 2015-02-09
I guess there's no such feature in postman as to run concurrent tests.
If i were you i would consider Apache jMeter which is used exactly for such scenarios.
Regarding Postman, the only thing that could more or less meet your needs is - Postman Runner. There you can specify the details:
The runs won't be concurrent, only consecutive.
Hope that helps. But do consider jMeter (you'll love it).
A shortcut for using a lambda with as a C function pointer is this:
"auto fun = +[](){}"
Using Curl as exmample (curl debug info)
auto callback = +[](CURL* handle, curl_infotype type, char* data, size_t size, void*){ //add code here :-) };
curl_easy_setopt(curlHande, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(curlHande,CURLOPT_DEBUGFUNCTION,callback);
Span is considered an in-line element. As such is basically constrains itself to the content within it. It more or less is transparent.
Think of it having the behavior of the 'b' tag.
It can be performed like <span style='font-weight: bold;'>bold text</span>
div is a block element.
As "docker ps --size" produces heavy IO load on host, it is not feasable running such command every minute in a production environment. Therefore we have to do a workaround in order to get desired container size or to be more precise, the size of the RW-Layer with a low impact to systems perfomance.
This approach gathers the "device name" of every container and then checks size of it using "df" command. Those "device names" are thin provisioned volumes that a mounted to / on each container. One problem still persists as this observed size also implies all the readonly-layers of underlying image. In order to address this we can simple check size of used container image and substract it from size of a device/thin_volume.
One should note that every image layer is realized as a kind of a lvm snapshot when using device mapper. Unfortunately I wasn't able to get my rhel system to print out those snapshots/layers. Otherwise we could simply collect sizes of "latest" snapshots. Would be great if someone could make things clear. However...
After some tests, it seems that creation of a container always adds an overhead of approx. 40MiB (tested with containers based on Image "httpd:2.4.46-alpine"):
Following shell prints results (in bytes) that match results from "docker ps --size" (but keep in mind mentioned overhead of 40MB)
for c in $(docker ps -q); do \
container_name=$(docker inspect -f "{{.Name}}" ${c} | sed 's/^\///g' ); \
device_n=$(docker inspect -f "{{.GraphDriver.Data.DeviceName}}" ${c} | sed 's/.*-//g'); \
device_size_kib=$(df -T | grep ${device_n} | awk '{print $4}'); \
device_size_byte=$((1024 * ${device_size_kib})); \
image_sha=$(docker inspect -f "{{.Image}}" ${c} | sed 's/.*://g' ); \
image_size_byte=$(docker image inspect -f "{{.Size}}" ${image_sha}); \
container_size_byte=$((${device_size_byte} - ${image_size_byte})); \
\
echo my_node_dm_device_size_bytes\{cname=\"${container_name}\"\} ${device_size_byte}; \
echo my_node_dm_container_size_bytes\{cname=\"${container_name}\"\} ${container_size_byte}; \
echo my_node_dm_image_size_bytes\{cname=\"${container_name}\"\} ${image_size_byte}; \
done

Do not forget to verify if your text editor encodes properly your code in UTF-8.
Otherwise, you may have invisible characters that are not interpreted as UTF-8.
The Bootstrap grid system has four classes:
xs (for phones)
sm (for tablets)
md (for desktops)
lg (for larger desktops)The classes above can be combined to create more dynamic and flexible layouts.
Tip: Each class scales up, so if you wish to set the same widths for xs and sm, you only need to specify xs.
OK, the answer is easy, but read on:
col-lg- stands for column large = 1200px
col-md- stands for column medium = 992px
col-xs- stands for column extra small = 768px
The pixel numbers are the breakpoints, so for example col-xs
is targeting the element when the window is smaller than 768px(likely mobile devices)...
I also created the image below to show how the grid system works, in this examples I use them with 3, like col-lg-6
to show you how the grid system work in the page, look at how lg
, md
and xs
are responsive to the window size:

Here is my pass at the problem. I modified the source code for copytree to keep the original functionality, but now no error occurs when the directory already exists.

Clearly explained here and rules to follow to use Variable Argument.
In Android Studio 2.3.3 I was able to get my AVD to start and run by changing Graphics
in the Emulated Performance
section from Automatic
to Software-GLES 2.0
:
I was able to infer this after following the advice at https://stackoverflow.com/a/44931679/1843329 and doing:
$ ./emulator -avd Nexus_4_API_21 -use-system-libs
which resulted in:
emulator: ERROR: Could not initialize OpenglES emulation, use '-gpu off' to disable it.
And when I did:
./emulator -avd Nexus_4_API_21 -use-system-libs -gpu off
the emulator then launched.
Select UIViewController on your storyboard an uncheck option Extend Edges Under Top Bars. Worked for me. : )
So, I had this code:
<div class="dropdown-select-wrapper" *ngIf="contentData">
<button mat-stroked-button [disableRipple]="true" class="mat-button" (click)="openSelect()" [ngClass]="{'only-icon': !contentData?.buttonText?.length}">
<i *ngIf="contentData.iconClassInfo" class="dropdown-icon {{contentData.iconClassInfo.name}}"></i>
<span class="button-text" *ngIf="contentData.buttonText">{{contentData.buttonText}}</span>
</button>
<mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();">
<mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
{{option[contentData.optionsStructure.keyName]}}
</mat-option>
</mat-select>
</div>
Here I was using standalone formControl, and I was getting the error we are talking about, which made no sense for me, since I wasn't working with formgroups or formarrays... it only disappeared when I added the *ngIf to the select it self, so is not being used before it actually exists. That's what solved the issue in my case.
<mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();" *ngIf="theFormControl">
<mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
{{option[contentData.optionsStructure.keyName]}}
</mat-option>
</mat-select>
You can make nginx ignore client aborts using:
location / {
proxy_ignore_client_abort on;
}
FWIW, I was able to setup a local RTSP server for testing purposes using simple-rtsp-server and ffmpeg following these steps:
rtsp-simple-server.yml
with this single line:
protocols: [tcp]
$ docker run --rm -it -v $PWD/rtsp-simple-server.yml:/rtsp-simple-server.yml -p 8554:8554 aler9/rtsp-simple-server
$ ffmpeg -re -stream_loop -1 -i test.mp4 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/live.stream
Once you have that running you can use ffplay to view the stream:
$ ffplay -rtsp_transport tcp rtsp://localhost:8554/live.stream
Note that simple-rtsp-server can also handle UDP streams (i.s.o. TCP) but that's tricky running the server as a Docker container.
You typically have to do this in a single syscall, or else you will get a race condition.
This will open for reading and writing, creating the file if necessary.
FILE *fp = fopen("scores.dat", "ab+");
If you want to read it and then write a new version from scratch, then do it as two steps.
FILE *fp = fopen("scores.dat", "rb");
if (fp) {
read_scores(fp);
}
// Later...
// truncates the file
FILE *fp = fopen("scores.dat", "wb");
if (!fp)
error();
write_scores(fp);
use this code:
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
const char Delete = (char)8;
e.Handled = !Char.IsDigit(e.KeyChar) && e.KeyChar != Delete;
}
Try this:
var charArray = "this is a test".ToCharArray().Select(c=>c.ToString());
Simple solution for all those who want the functionality in all browsers:
HTML
<input type="password" id="password">
<input type="text" id="passwordHide" style="display:none;">
<input type="checkbox" id="passwordSwitch" checked="checked">Hide password
jQuery
$("#passwordSwitch").change(function(){
var p = $('#password');
var h = $('#passwordHide');
h.val(p.val());
if($(this).attr('checked')=='checked'){
h.hide();
p.show();
}else{
p.hide();
h.show();
}
});
With LINQ, and using C# (I don't know VB much these days):
bool b = listOfStrings.Any(s=>myString.Contains(s));
or (shorter and more efficient, but arguably less clear):
bool b = listOfStrings.Any(myString.Contains);
If you were testing equality, it would be worth looking at HashSet
etc, but this won't help with partial matches unless you split it into fragments and add an order of complexity.
update: if you really mean "StartsWith", then you could sort the list and place it into an array ; then use Array.BinarySearch
to find each item - check by lookup to see if it is a full or partial match.
It's already been answered how to get offset in minutes as an integer, but in case anyone wants the local GMT offset as a string e.g. "+1130"
:
function pad(number, length){
var str = "" + number
while (str.length < length) {
str = '0'+str
}
return str
}
var offset = new Date().getTimezoneOffset()
offset = ((offset<0? '+':'-')+ // Note the reversed sign!
pad(parseInt(Math.abs(offset/60)), 2)+
pad(Math.abs(offset%60), 2))
Get the value of your textboxes using val()
and store them in a variable. Pass those values through $.post
. In using the $.Post Submit button
you can actually remove the form.
<script>
username = $("#username").val();
password = $("#password").val();
$("#post-btn").click(function(){
$.post("process.php", { username:username, password:password } ,function(data){
alert(data);
});
});
</script>
You can use the code below if you dont want to use jQuery UI or any third party pluggin. It's only plain jQuery.

Easy code and solution using Microsoft.Office.Interop.Word
to converd WORD in PDF
using Word = Microsoft.Office.Interop.Word;
private void convertDOCtoPDF()
{
object misValue = System.Reflection.Missing.Value;
String PATH_APP_PDF = @"c:\..\MY_WORD_DOCUMENT.pdf"
var WORD = new Word.Application();
Word.Document doc = WORD.Documents.Open(@"c:\..\MY_WORD_DOCUMENT.docx");
doc.Activate();
doc.SaveAs2(@PATH_APP_PDF, Word.WdSaveFormat.wdFormatPDF, misValue, misValue, misValue,
misValue, misValue, misValue, misValue, misValue, misValue, misValue);
doc.Close();
WORD.Quit();
releaseObject(doc);
releaseObject(WORD);
}
Add this procedure to release memory:
private void releaseObject(object obj)
{
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
obj = null;
}
catch (Exception ex)
{
//TODO
}
finally
{
GC.Collect();
}
}
I have grown fond of the LoDash / Underscore when writing larger projects.
Adding by obj['key']
or obj.key
are all solid pure JavaScript answers. However both of LoDash and Underscore libraries do provide many additional convenient functions when working with Objects and Arrays in general.
.push()
is for Arrays, not for objects.
Depending what you are looking for, there are two specific functions that may be nice to utilize and give functionality similar to the the feel of arr.push()
. For more info check the docs, they have some great examples there.
The second object will overwrite or add to the base object.
undefined
values are not copied.
var obj = {key1: "value1", key2: "value2"};
var obj2 = {key2:"value4", key3: "value3", key4: undefined};
_.merge(obj, obj2);
console.log(obj);
// ? {key1: "value1", key2: "value4", key3: "value3"}
The second object will overwrite or add to the base object.
undefined
will be copied.
var obj = {key1: "value1", key2: "value2"};
var obj2 = {key2:"value4", key3: "value3", key4: undefined};
_.extend(obj, obj2);
console.log(obj);
// ? {key1: "value1", key2: "value4", key3: "value3", key4: undefined}
The second object contains defaults that will be added to base object if they don't exist.
undefined
values will be copied if key already exists.
var obj = {key3: "value3", key5: "value5"};
var obj2 = {key1: "value1", key2:"value2", key3: "valueDefault", key4: "valueDefault", key5: undefined};
_.defaults(obj, obj2);
console.log(obj);
// ? {key3: "value3", key5: "value5", key1: "value1", key2: "value2", key4: "valueDefault"}
In addition, it may be worthwhile mentioning jQuery.extend, it functions similar to _.merge and may be a better option if you already are using jQuery.
The second object will overwrite or add to the base object.
undefined
values are not copied.
var obj = {key1: "value1", key2: "value2"};
var obj2 = {key2:"value4", key3: "value3", key4: undefined};
$.extend(obj, obj2);
console.log(obj);
// ? {key1: "value1", key2: "value4", key3: "value3"}
It may be worth mentioning the ES6/ ES2015 Object.assign, it functions similar to _.merge and may be the best option if you already are using an ES6/ES2015 polyfill like Babel if you want to polyfill yourself.
The second object will overwrite or add to the base object.
undefined
will be copied.
var obj = {key1: "value1", key2: "value2"};
var obj2 = {key2:"value4", key3: "value3", key4: undefined};
Object.assign(obj, obj2);
console.log(obj);
// ? {key1: "value1", key2: "value4", key3: "value3", key4: undefined}
It turns out that Google Picasa (free) will do this for you now. If you have it open, when you hit it will save the screen shot to a file and load it into Picasa. In my experience, it works great!
Based on your comment, moddify this:
$( '.bgHeaderH2' ).html (); // will return whatever is inside the DIV
to:
$( '.bgHeaderH2', $( this ) ).html (); // will return whatever is inside the DIV

Under Windows 7, open the Event Viewer. You can do this the way Gishu suggested for XP, typing eventvwr
from the command line, or by opening the Control Panel, selecting System and Security, then Administrative Tools and finally Event Viewer. It may require UAC approval or an admin password.
In the left pane, expand Windows Logs and then System. You can filter the logs with Filter Current Log... from the Actions pane on the right and selecting "Service Control Manager." Or, depending on why you want this information, you might just need to look through the Error entries.
The actual log entry pane (not shown) is pretty user-friendly and self-explanatory. You'll be looking for messages like the following:
"The Praxco Assistant service entered the stopped state."
"The Windows Image Acquisition (WIA) service entered the running state."
"The MySQL service terminated unexpectedly. It has done this 3 time(s)."
You can use this library from JSON.org to translate your string into a JSON object.
var var1_obj = JSON.parse(var1);
Or you can use the jquery-json library as well.
var var1_obj = $.toJSON(var1);
HTTP and HTTPS:
const getScript = (url) => {
return new Promise((resolve, reject) => {
const http = require('http'),
https = require('https');
let client = http;
if (url.toString().indexOf("https") === 0) {
client = https;
}
client.get(url, (resp) => {
let data = '';
// A chunk of data has been recieved.
resp.on('data', (chunk) => {
data += chunk;
});
// The whole response has been received. Print out the result.
resp.on('end', () => {
resolve(data);
});
}).on("error", (err) => {
reject(err);
});
});
};
(async (url) => {
console.log(await getScript(url));
})('https://sidanmor.com/');
Because the view must return render
, not just call it. Change the last line to
return render(request, 'auth_lifecycle/user_profile.html',
context_instance=RequestContext(request))
the dichotomy... Are they non-overlapping? Only non-overlapping parts of a whole can make a dichotomy. As i see it:
throw new IllegalArgumentException(new NullPointerException(NULL_ARGUMENT_IN_METHOD_BAD_BOY_BAD));
I think one of the original questions here was not answered. I believe that vanilla eval() is not used because then angular apps would not work as Chrome apps, which explicitly prevent eval() from being used for security reasons.
Node.JS does not fully support ES6 currently, so you can either use asyncawait module or transpile it using Bable.
install
npm install --save asyncawait
helloz.js
var async = require('asyncawait/async');
var await = require('asyncawait/await');
(async (function testingAsyncAwait() {
await (console.log("Print me!"));
}))();
<?php

'menu_class' => false,
'items_wrap' => '%3$s',

You could also use T-Regx library:
pattern('\D')->remove($c)
T-Regx also:
false
, null
or warnings)A very simple approach independent of python version was missing in already given answers which you can use most of the time (at least I do):
new_list = my_list * 1 #Solution 1 when you are not using nested lists
However, If my_list contains other containers (for eg. nested lists) you must use deepcopy as others suggested in the answers above from the copy library. For example:
import copy
new_list = copy.deepcopy(my_list) #Solution 2 when you are using nested lists
.Bonus: If you don't want to copy elements use (aka shallow copy):
new_list = my_list[:]
Let's understand difference between Solution#1 and Solution #2
>>> a = range(5)
>>> b = a*1
>>> a,b
([0, 1, 2, 3, 4], [0, 1, 2, 3, 4])
>>> a[2] = 55
>>> a,b
([0, 1, 55, 3, 4], [0, 1, 2, 3, 4])
As you can see Solution #1 worked perfectly when we were not using the nested lists. Let's check what will happen when we apply solution #1 to nested lists.
>>> from copy import deepcopy
>>> a = [range(i,i+4) for i in range(3)]
>>> a
[[0, 1, 2, 3], [1, 2, 3, 4], [2, 3, 4, 5]]
>>> b = a*1
>>> c = deepcopy(a)
>>> for i in (a, b, c): print i
[[0, 1, 2, 3], [1, 2, 3, 4], [2, 3, 4, 5]]
[[0, 1, 2, 3], [1, 2, 3, 4], [2, 3, 4, 5]]
[[0, 1, 2, 3], [1, 2, 3, 4], [2, 3, 4, 5]]
>>> a[2].append('99')
>>> for i in (a, b, c): print i
[[0, 1, 2, 3], [1, 2, 3, 4], [2, 3, 4, 5, 99]]
[[0, 1, 2, 3], [1, 2, 3, 4], [2, 3, 4, 5, 99]] #Solution#1 didn't work in nested list
[[0, 1, 2, 3], [1, 2, 3, 4], [2, 3, 4, 5]] #Solution #2 - DeepCopy worked in nested list
maxDate: new Date()
its working fine for me disable with current date in date range picker
There is Javascript function isNaN which will do that.
isNaN(90)
=>false
so you can check numeric by
!isNaN(90)
=>true
An uninitialized Boolean
member (actually a reference to an object of type Boolean
) will have the default value of null
.
An uninitialized boolean
(primitive) member will have the default value of false
.
While @Eli is quite correct that there usually isn't much of a need to do it, it is possible. savefig
takes a bbox_inches
argument that can be used to selectively save only a portion of a figure to an image.
Here's a quick example:
import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np
# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')
ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')
# Save the full figure...
fig.savefig('full_figure.png')
# Save just the portion _inside_ the second axis's boundaries
extent = ax2.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)
# Pad the saved area by 10% in the x-direction and 20% in the y-direction
fig.savefig('ax2_figure_expanded.png', bbox_inches=extent.expanded(1.1, 1.2))
The full figure:
Area inside the second subplot:
Area around the second subplot padded by 10% in the x-direction and 20% in the y-direction:
For the Python module import to work, you must have "src" in your path, not "gen_py/lib".
When processing an import like import gen_py.lib
, it looks for a module gen_py
, then looks for a submodule lib
.
As the module gen_py
won't be in "../gen_py/lib" (it'll be in ".."), the path you added will do nothing to help the import process.
Depending on where you're running it from, try adding the relative path to the "src" folder. Perhaps it's sys.path.append('..')
. You might also have success running the script while inside the src folder directly, via relative paths like python main/MyServer.py
Put the modal and javascript into the partial view. Then call the partial view in your page. This will handle form submission too.
Partial View
<div id="confirmDialog" class="modal fade" data-backdrop="false">
<div class="modal-dialog" data-backdrop="false">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Missing Service Order</h4>
</div>
<div class="modal-body">
<p>You have not entered a Service Order. Do you want to continue?</p>
</div>
<div class="modal-footer">
<input id="btnSubmit" type="submit" class="btn btn-primary"
value="Submit" href="javascript:"
onClick="document.getElementById('Coordinate').submit()" />
<button type="button" class="btn btn-default" data-
dismiss="modal">Cancel</button>
</div>
</div>
</div>
</div>
Javascript
<script type="text/javascript" language="javascript">
$(document).ready(function () {
$("#Coordinate").on('submit',
function (e) {
if ($("#ServiceOrder").val() == '') {
e.preventDefault();
$('#confirmDialog').modal('show');
}
});
});
</script>
Then just call your partial inside the form of your page.
Create.cshtml
@using (Html.BeginForm("Edit","Home",FormMethod.Post, new {id ="Coordinate"}))
{
//Form Code
@Html.Partial("ConfirmDialog")
}
Seaborn takes care of a lot of the manual work and automatically plots a gradient at the side of the chart etc.
import numpy as np
import seaborn as sns
import matplotlib.pylab as plt
uniform_data = np.random.rand(10, 12)
ax = sns.heatmap(uniform_data, linewidth=0.5)
plt.show()
Or, you can even plot upper / lower left / right triangles of square matrices, for example a correlation matrix which is square and is symmetric, so plotting all values would be redundant anyway.
corr = np.corrcoef(np.random.randn(10, 200))
mask = np.zeros_like(corr)
mask[np.triu_indices_from(mask)] = True
with sns.axes_style("white"):
ax = sns.heatmap(corr, mask=mask, vmax=.3, square=True, cmap="YlGnBu")
plt.show()
I know this is old, but since Postgresql 9.3 there is an option to use a keyword "LATERAL" to use RELATED subqueries inside of JOINS, so the query from the question would look like:
SELECT
name, author_id, count(*), t.total
FROM
names as n1
INNER JOIN LATERAL (
SELECT
count(*) as total
FROM
names as n2
WHERE
n2.id = n1.id
AND n2.author_id = n1.author_id
) as t ON 1=1
GROUP BY
n1.name, n1.author_id

I think it is better to copy files from your local computer, because if files number or file size is very big, copying process could be interrupted if your current ssh session would be lost (broken pipe or whatever).
If you have configured ssh key to connect to your remote server, you could use the following command:
rsync -avP -e "ssh -i /home/local_user/ssh/key_to_access_remote_server.pem" remote_user@remote_host.ip:/home/remote_user/file.gz /home/local_user/Downloads/
Where v
option is --verbose
, a
option is --archive
- archive mode, P
option same as --partial
- keep partially transferred files, e
option is --rsh=COMMAND
- specifying the remote shell to use.
There are two options, really:
E.g.,
int[] ints = {11367, 11358, 11421, 11530, 11491, 11218, 11789};
Arrays.sort(ints);
System.out.println(Arrays.asList(ints));
That of course assumes that you already have your integers as an array. If you need to parse those first, look for String.split and Integer.parseInt.
Why do people keep confusing strings with string literals? The accepted answer is a great answer to a different question; not to this one.
I know this is an old topic, but I came here with possibly the same question as the OP, and it is frustrating to see how people keep misreading it. Or maybe I am misreading it, I don't know.
Roughly speaking, a string is a region of computer memory that, during the execution of a program, contains a sequence of bytes that can be mapped to text characters. A string literal, on the other hand, is a piece of source code, not yet compiled, that represents the value used to initialize a string later on, during the execution of the program in which it appears.
In C#, the statement...
string query = "SELECT foo, bar"
+ " FROM table"
+ " WHERE id = 42";
... does not produce a three-line string but a one liner; the concatenation of three strings (each initialized from a different literal) none of which contains a new-line modifier.
What the OP seems to be asking -at least what I would be asking with those words- is not how to introduce, in the compiled string, line breaks that mimick those found in the source code, but how to break up for clarity a long, single line of text in the source code without introducing breaks in the compiled string. And without requiring an extended execution time, spent joining the multiple substrings coming from the source code. Like the trailing backslashes within a multiline string literal in javascript or C++.
Suggesting the use of verbatim strings, nevermind StringBuilder
s, String.Join
s or even nested functions with string reversals and what not, makes me think that people are not really understanding the question. Or maybe I do not understand it.
As far as I know, C# does not (at least in the paleolithic version I am still using, from the previous decade) have a feature to cleanly produce multiline string literals that can be resolved during compilation rather than execution.
Maybe current versions do support it, but I thought I'd share the difference I perceive between strings and string literals.
UPDATE:
(From MeowCat2012's comment) You can. The "+" approach by OP is the best. According to spec the optimization is guaranteed: http://stackoverflow.com/a/288802/9399618
You can make a simple hashMap yourself. What a hashMap does is storing items in a array using the hash as index/key. Hash-functions give collisions once in a while (not often, but they may do), so you have to store multiple items for an entry in the hashMap. That simple is a hashMap:
class IEqualityComparer {
public function equals($x, $y) {
throw new Exception("Not implemented!");
}
public function getHashCode($obj) {
throw new Exception("Not implemented!");
}
}
class HashMap {
private $map = array();
private $comparer;
public function __construct(IEqualityComparer $keyComparer) {
$this->comparer = $keyComparer;
}
public function has($key) {
$hash = $this->comparer->getHashCode($key);
if (!isset($this->map[$hash])) {
return false;
}
foreach ($this->map[$hash] as $item) {
if ($this->comparer->equals($item['key'], $key)) {
return true;
}
}
return false;
}
public function get($key) {
$hash = $this->comparer->getHashCode($key);
if (!isset($this->map[$hash])) {
return false;
}
foreach ($this->map[$hash] as $item) {
if ($this->comparer->equals($item['key'], $key)) {
return $item['value'];
}
}
return false;
}
public function del($key) {
$hash = $this->comparer->getHashCode($key);
if (!isset($this->map[$hash])) {
return false;
}
foreach ($this->map[$hash] as $index => $item) {
if ($this->comparer->equals($item['key'], $key)) {
unset($this->map[$hash][$index]);
if (count($this->map[$hash]) == 0)
unset($this->map[$hash]);
return true;
}
}
return false;
}
public function put($key, $value) {
$hash = $this->comparer->getHashCode($key);
if (!isset($this->map[$hash])) {
$this->map[$hash] = array();
}
$newItem = array('key' => $key, 'value' => $value);
foreach ($this->map[$hash] as $index => $item) {
if ($this->comparer->equals($item['key'], $key)) {
$this->map[$hash][$index] = $newItem;
return;
}
}
$this->map[$hash][] = $newItem;
}
}
For it to function you also need a hash-function for your key and a comparer for equality (if you only have a few items or for another reason don't need speed you can let the hash-function return 0; all items will be put in same bucket and you will get O(N) complexity)
Here is an example:
class IntArrayComparer extends IEqualityComparer {
public function equals($x, $y) {
if (count($x) !== count($y))
return false;
foreach ($x as $key => $value) {
if (!isset($y[$key]) || $y[$key] !== $value)
return false;
}
return true;
}
public function getHashCode($obj) {
$hash = 0;
foreach ($obj as $key => $value)
$hash ^= $key ^ $value;
return $hash;
}
}
$hashmap = new HashMap(new IntArrayComparer());
for ($i = 0; $i < 10; $i++) {
for ($j = 0; $j < 10; $j++) {
$hashmap->put(array($i, $j), $i * 10 + $j);
}
}
echo $hashmap->get(array(3, 7)) . "<br/>";
echo $hashmap->get(array(5, 1)) . "<br/>";
echo ($hashmap->has(array(8, 4))? 'true': 'false') . "<br/>";
echo ($hashmap->has(array(-1, 9))? 'true': 'false') . "<br/>";
echo ($hashmap->has(array(6))? 'true': 'false') . "<br/>";
echo ($hashmap->has(array(1, 2, 3))? 'true': 'false') . "<br/>";
$hashmap->del(array(8, 4));
echo ($hashmap->has(array(8, 4))? 'true': 'false') . "<br/>";
Which gives as output:
37
51
true
false
false
false
false
public Bitmap bitmapResize(Bitmap imageBitmap) {

Use the operator sizeof
, it will give you the size of a type expressed in byte. One byte is eight bits. See the following program:
#include <iostream>
int main(int,char**)
{
std::cout << "unsigned long long " << sizeof(unsigned long long) << "\n";
std::cout << "unsigned long long int " << sizeof(unsigned long long int) << "\n";
return 0;
}
If you want the file size of multiple files in a directory, use Files.walkFileTree
. You can obtain the size from the BasicFileAttributes
that you'll receive.
This is much faster then calling .length()
on the result of File.listFiles()
or using Files.size()
on the result of Files.newDirectoryStream()
. In my test cases it was about 100 times faster.
^\d{0,2}\.?\d{1,2}$
You can use this function to disable the form:
function disableForm(formID){
$('#' + formID).children(':input').attr('disabled', 'disabled');
}
Note that it uses jQuery.
Give a class .border-lb
and give this CSS
.border-lb {border: 1px solid #ccc; border-width: 0 0 1px 1px;}
And the HTML
<table width="770">
<tr>
<td class="border-lb">picture (border only to the left and bottom ) </td>
<td>text</td>
</tr>
<tr>
<td>text</td>
<td class="border-lb">picture (border only to the left and bottom) </td>
</tr>
</table>
The version of the errorHandler middleware bundled with some (perhaps older?) versions of express seems to have the status code hardcoded. The version documented here: http://www.senchalabs.org/connect/errorHandler.html on the other hand lets you do what you are trying to do. So, perhaps trying upgrading to the latest version of express/connect.
This works fine for me
// assuming this fills the List
List<Dictionary<string, string>> obj = this.getData();
List<Dictionary<string, string>> objCopy = new List<Dictionary<string, string>>(obj);
As Tomer Wolberg describes in the comments, this does not work if the value type is a mutable class.
Ref - Refresh Expired JWT Example
Another alternative is that once the JWT has expired, the user/system will make a call to another url suppose /refreshtoken. Also along with this request the expired JWT should be passed. The Server will then return a new JWT which can be used by the user/system.
You can delete the node from the master by issuing:
kubectl delete node hostname.company.net
The NOTReady status probably means that the master can't access the kubelet service. Check if everything is OK on the client.
This solution worked for me using PyQt5 version 5.15.0
import sys
from PyQt5 import QtWidgets, QtWebEngineWidgets
from PyQt5.QtCore import QUrl
from PyQt5.QtGui import QPageLayout, QPageSize
from PyQt5.QtWidgets import QApplication
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
loader = QtWebEngineWidgets.QWebEngineView()
loader.setZoomFactor(1)
layout = QPageLayout()
layout.setPageSize(QPageSize(QPageSize.A4Extra))
layout.setOrientation(QPageLayout.Portrait)
loader.load(QUrl('https://stackoverflow.com/questions/23359083/how-to-convert-webpage-into-pdf-by-using-python'))
loader.page().pdfPrintingFinished.connect(lambda *args: QApplication.exit())

loader.loadFinished.connect(emit_pdf)
sys.exit(app.exec_())
A base R option is the split()
-lapply()
-do.call()
idiom:
> do.call(rbind, lapply(split(test, test$id), head, 1))
id string
1 1 A
2 2 B
3 3 C
4 4 D
5 5 E
A more direct option is to lapply()
the [
function:
> do.call(rbind, lapply(split(test, test$id), `[`, 1, ))
id string
1 1 A
2 2 B
3 3 C
4 4 D
5 5 E
The comma-space 1, )
at the end of the lapply()
call is essential as this is equivalent of calling [1, ]
to select first row and all columns.
Replace this:
var cat = $.jqURL.get('category');
var $dd = $('#cbCategory');
var $options = $('option', $dd);
$options.each(function() {
if ($(this).text() == cat)
$(this).select(); // This is where my problem is
});
With this:
$('#cbCategory').val(cat);
Calling val()
on a select list will automatically select the option with that value, if any.
There are very few real use cases in which being able to evaluate a String
as a fragment of Java code is necessary or desirable. That is, asking how to do this is really an XY problem: you actually have a different problem, which can be solved a different way.
First ask yourself, where did this String
that you wish to evaluate come from? Did another part of your program generate it, or was it input provided by the user?
Another part of my program generated it: so, you want one part of your program to decide the kind of operation to perform, but not perform the operation, and a second part that performs the chosen operation. Instead of generating and then evaluating a String
, use the Strategy, Command or Builder design pattern, as appropriate for your particular case.
It is user input: the user could input anything, including commands that, when executed, could cause your program to misbehave, crash, expose information that should be secret, damage persistent information (such as the content of a database), and other such nastiness. The only way to prevent that would be to parse the String
yourself, check it was not malicious, and then evaluate it. But parsing it yourself is much of the work that the requested eval
function would do, so you have saved yourself nothing. Worse still, checking that arbitrary Java
was not malicious is impossible, because checking that is the halting problem.
It is user input, but the syntax and semantics of permitted text to evaluate is greatly restricted: No general purpose facility can easily implement a general purpose parser and evaluator for whatever restricted syntax and semantics you have chosen. What you need to do is implement a parser and evaluator for your chosen syntax and semantics. If the task is simple, you could write a simple recursive-descent or finite-state-machine parser by hand. If the task is difficult, you could use a compiler-compiler (such as ANTLR) to do some of the work for you.
I just want to implement a desktop calculator!: A homework assignment, eh? If you could implement the evaluation of the input expression using a provided eval
function, it would not be much of a homework assignment, would it? Your program would be three lines long. Your instructor probably expects you to write the code for a simple arithmetic parser/evaluator. There is well known algorithm, shunting-yard, which you might find useful.
In my case this was happening with a Laravel queue worker. The system logs did not mention any killing so I looked further and it turned out that the worker was basically killing itself because of a job that exceeded the memory limit (which is set to 128M by default).
Running the queue worker with --timeout=600
and --memory=1024
fixed the problem for me.
I had the same issue and eventually chose to use a Rectangle element:
<Rectangle HorizontalAlignment="Stretch" Fill="Blue" Height="4"/>
In my opinion it's somewhat easier to modify/shape than a separator.
Of course the Separator
is a very easy and neat solution for simple separations :)
ngStyle
accepts a map:
$scope.myStyle = {
"width" : "900px",
"background" : "red"
};
In intellij you can auto generate toString method by pressing alt+inset and then selecting toString() here is an out put for a test class:
public class test {
int a;
char b;
String c;
Test2 test2;
@Override
public String toString() {
return "test{" +
"a=" + a +
", b=" + b +
", c='" + c + '\'' +
", test2=" + test2 +
'}';
}
}
As you can see, it generates a String by concatenating, several attributes of the class, for primitives it will print their values and for reference types it will use their class type (in this case to string method of Test2).
I was able to use Joey's Answer to create a function:
Use it as:
@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
SET "MYTEXT=jump over the chair"
echo !MYTEXT!
call:ReplaceText "!MYTEXT!" chair table RESULT
echo !RESULT!
GOTO:EOF
And these Functions to the bottom of your Batch File.
:FUNCTIONS
@REM FUNCTIONS AREA
GOTO:EOF
EXIT /B
:ReplaceText
::Replace Text In String
::USE:
:: CALL:ReplaceText "!OrginalText!" OldWordToReplace NewWordToUse Result
::Example
::SET "MYTEXT=jump over the chair"
:: echo !MYTEXT!
:: call:ReplaceText "!MYTEXT!" chair table RESULT
:: echo !RESULT!
::
:: Remember to use the "! on the input text, but NOT on the Output text.
:: The Following is Wrong: "!MYTEXT!" !chair! !table! !RESULT!
:: ^^Because it has a ! around the chair table and RESULT
:: Remember to add quotes "" around the MYTEXT Variable when calling.
:: If you don't add quotes, it won't treat it as a single string
::
set "OrginalText=%~1"
set "OldWord=%~2"
set "NewWord=%~3"
call set OrginalText=%%OrginalText:!OldWord!=!NewWord!%%
SET %4=!OrginalText!
GOTO:EOF
And remember you MUST add "SETLOCAL ENABLEDELAYEDEXPANSION" to the top of your batch file or else none of this will work properly.
SETLOCAL ENABLEDELAYEDEXPANSION
@REM # Remember to add this to the top of your batch file.
The two-line summary:
lambda
keyword: unnecessary, occasionally useful. If you find yourself doing anything remotely complex with it, put it away and define a real function.In c/cpp there is no shortcut but to initialize all the arrays with the zero subscript.Ex:
int arr[10] = {0};
But in java there is a magic tool called Arrays.fill() which will fill all the values in an array with the integer of your choice.Ex:
import java.util.Arrays;
public class Main
{
public static void main(String[] args)
{
int ar[] = {2, 2, 1, 8, 3, 2, 2, 4, 2};
Arrays.fill(ar, 10);
System.out.println("Array completely filled" +
" with 10\n" + Arrays.toString(ar));
}
}
Try adding this at the end of your code:
import matplotlib.pyplot as plt
plt.title('add title here')
if you want to hold the arguments from Terminal, try the following code:
A = ARGV[0].to_i
B = ARGV[1].to_i
puts "#{A} + #{B} = #{A + B}"

Check/do the following:
1) Under "Window --> Preferences --> Java --> Compiler --> Classfile Generation", all options have to be to True:
(1) Add variable attributes...
(2) Add line number attributes...
(3) Add source file name...
(4) Preserve unused (never read) local variables
2) In .settings folder of your project, look for a file called org.eclipse.jdt.core.prefs. Verify or set org.eclipse.jdt.core.compiler.debug.lineNumber=generate
3) If error window still appears, click the checkbox to not display the error message.
4) Clean and build the project. Start debugging.
Normally the error window is not displayed any more and the debugging informations is displayed correctly.

Use the NORMINV
function together with RAND()
:
=NORMINV(RAND(),10,7)
To keep your set of random values from changing, select all the values, copy them, and then paste (special) the values back into the same range.
Sample output (column A), 500 numbers generated with this formula:
You can groupby the 'name'
and 'month'
columns, then call transform
which will return data aligned to the original df and apply a lambda where we join
the text entries:
In [119]:
df['text'] = df[['name','text','month']].groupby(['name','month'])['text'].transform(lambda x: ','.join(x))
df[['name','text','month']].drop_duplicates()
Out[119]:
name text month
0 name1 hej,du 11
2 name1 aj,oj 12
4 name2 fin,katt 11
6 name2 mycket,lite 12
I sub the original df by passing a list of the columns of interest df[['name','text','month']]
here and then call drop_duplicates
EDIT actually I can just call apply
and then reset_index
:
In [124]:
df.groupby(['name','month'])['text'].apply(lambda x: ','.join(x)).reset_index()
Out[124]:
name month text
0 name1 11 hej,du
1 name1 12 aj,oj
2 name2 11 fin,katt
3 name2 12 mycket,lite
update
the lambda
is unnecessary here:
In[38]:
df.groupby(['name','month'])['text'].apply(','.join).reset_index()
Out[38]:
name month text
0 name1 11 du
1 name1 12 aj,oj
2 name2 11 fin,katt
3 name2 12 mycket,lite
There is no real need to create a war to run it from Tomcat. You can follow these steps
Create a folder in webapps folder e.g. MyApp
Put your html and css in that folder and name the html file, which you want to be the starting page for your application, index.html
Start tomcat and point your browser to url "http://localhost:8080/MyApp". Your index.html page will pop up in the browser
No, there isn't.
<br>
is an HTML ELEMENT. It can't be replaced by a text node or part of a text node.
You can create a new-line effect using CR/LF inside a <pre>
element like below:
<pre>Line 1_x000D_
Line 2</pre>
_x000D_
But this is not the same as a <br>

Code snippet for piping content from web via http(s) to filesystem. As @starbeamrainbowlabs noticed event finish
does job
var tmpFile = "/tmp/somefilename.doc";
var ws = fs.createWriteStream(tmpFile);
ws.on('finish', function() {
// pipe done here, do something with file
});
var client = url.slice(0, 5) === 'https' ? https : http;
client.get(url, function(response) {
return response.pipe(ws);
});
Try executing below command,
java -help
It gives option as,
-version print product version and exit
java -version is the correct command to execute

np.split()
is pretty flexible - let's split an original DF into 3 DFs at columns with indexes [2,3]

Something like this:
var $div = $('div'),
bg = $div.css('background-image');
if (bg) {
var src = bg.replace(/(^url\()|(\)$|[\"\'])/g, ''),
$img = $('<img>').attr('src', src).on('load', function() {

You are printing the enum object. Use the .value
attribute if you wanted just to print that:
print(D.x.value)
See the Programmatic access to enumeration members and their attributes section:
If you have an enum member and need its name or value:
>>> >>> member = Color.red >>> member.name 'red' >>> member.value 1
You could add a __str__
method to your enum, if all you wanted was to provide a custom string representation:
class D(Enum):
def __str__(self):
return str(self.value)
x = 1
y = 2
Demo:
>>> from enum import Enum
>>> class D(Enum):
... def __str__(self):
... return str(self.value)
... x = 1
... y = 2
...
>>> D.x
<D.x: 1>
>>> print(D.x)
1
Since there is a delimiter, you should use that instead of worrying about how long the md5 is.
>>> s = "416d76b8811b0ddae2fdad8f4721ddbe|d4f656ee006e248f2f3a8a93a8aec5868788b927|12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f"
>>> md5sum, delim, rest = s.partition('|')
>>> md5sum
'416d76b8811b0ddae2fdad8f4721ddbe'
Alternatively
>>> md5sum, sha1sum, sha5sum = s.split('|')
>>> md5sum
'416d76b8811b0ddae2fdad8f4721ddbe'
>>> sha1sum
'd4f656ee006e248f2f3a8a93a8aec5868788b927'
>>> sha5sum
'12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f'
Per Byron's answer, you can't set networkaddress.cache.ttl
or networkaddress.cache.negative.ttl
as System Properties by using the -D
flag or calling System.setProperty
because these are not System properties - they are Security properties.
If you want to use a System property to trigger this behavior (so you can use the -D
flag or call System.setProperty
), you will want to set the following System property:
-Dsun.net.inetaddr.ttl=0
This system property will enable the desired effect.
But be aware: if you don't use the -D
flag when starting the JVM process and elect to call this from code instead:
java.security.Security.setProperty("networkaddress.cache.ttl" , "0")
This code must execute before any other code in the JVM attempts to perform networking operations.
This is important because, for example, if you called Security.setProperty
in a .war file and deployed that .war to Tomcat, this wouldn't work: Tomcat uses the Java networking stack to initialize itself much earlier than your .war's code is executed. Because of this 'race condition', it is usually more convenient to use the -D
flag when starting the JVM process.
If you don't use -Dsun.net.inetaddr.ttl=0
or call Security.setProperty
, you will need to edit $JRE_HOME/lib/security/java.security
and set those security properties in that file, e.g.
networkaddress.cache.ttl = 0
networkaddress.cache.negative.ttl = 0
But pay attention to the security warnings in the comments surrounding those properties. Only do this if you are reasonably confident that you are not susceptible to DNS spoofing attacks.
From the Windows command line reference:
To parse a file, ignoring commented lines, type:
for /F "eol=; tokens=2,3* delims=," %i in (myfile.txt) do @echo %i %j %k
This command parses each line in Myfile.txt, ignoring lines that begin with a semicolon and passing the second and third token from each line to the FOR body (tokens are delimited by commas or spaces). The body of the FOR statement references %i to get the second token, %j to get the third token, and %k to get all of the remaining tokens.
If the file names that you supply contain spaces, use quotation marks around the text (for example, "File Name"). To use quotation marks, you must use usebackq. Otherwise, the quotation marks are interpreted as defining a literal string to parse.
By the way, you can find the command-line help file on most Windows systems at:
"C:\WINDOWS\Help\ntcmds.chm"
n = 2
a=dataframe['name'].value_counts()[:n].index.tolist()
dataframe["name"].value_counts()[a]
The easiest way to do it, at least for me, is:
Conditional format-> Add new rule->Set your own formula:
=ISNA(MATCH(A2;$B:$B;0))
Where A2 is the first element in column A to be compared and B is the column where A's element will be searched.
Once you have set the formula and picked the format, apply this rule to all elements in the column.
Hope this helps
Django > 2.0 version:
The approach is essentially identical with the one given in Yuji 'Tomita' Tomita's Answer. Affected, however, is the syntax:
# URLconf
...
urlpatterns = [
path(
'project_config/<product>/',
views.get_product,
name='project_config'
),
path(
'project_config/<product>/<project_id>/',
views.get_product,
name='project_config'
),
]
# View (in views.py)
def get_product(request, product, project_id='None'):
# Output the appropriate product
...
Using path()
you can also pass extra arguments to a view with the optional argument kwargs
that is of type dict
. In this case your view would not need a default for the attribute project_id
:
...
path(
'project_config/<product>/',
views.get_product,
kwargs={'project_id': None},
name='project_config'
),
...
For how this is done in the most recent Django version, see the official docs about URL dispatching.
I don't think enough time was paid attention to the schema considerations brought up in the original post. So, here is something to consider for any newbies.
Let's say you went ahead and built this solution. All of your menial values are conctenated into a single value and stored in the database. You are indeed saving [a little] space in your database and some time coding.
Now let's consider that you must perform the frequent and easy task of adding a new checkbox between the current checkboxes 3 & 4. Your development manager, customer, whatever expects this to be a simple change.
So you add the checkbox to the UI (the easy part). Your looping code would already concatenate the values no matter how many checkboxes. You also figure your database field is just a varchar or other string type so it should be fine as well.
What happens when customers or you try to view the data from before the change? You're essentially serializing from left to right. However, now the values after 3 are all off by 1 character. What are you going to do with all of your existing data? Are you going write an application, pull it all back out of the database, process it to add in a default value for the new question position and then store it all back in the database? What happens when you have several new values a week or month apart? What if you move the locations and jQuery processes them in a different order? All your data is hosed and has to be reprocessed again to rearrange it.
The whole concept of NOT providing a tight key-value relationship is ludacris and will wind up getting you into trouble sooner rather than later. For those of you considering this, please don't. The other suggestions for schema changes are fine. Use a child table, more fields in the main table, a question-answer table, etc. Just don't store non-labeled data when the structure of that data is subject to change.
Update: created a js fiddle here to see it live: http://jsfiddle.net/HFMvX/
I went through tons of google searches and didn't find anything satisfying. i like how passpack have done it so essentially reverse-engineered their approach, here we go:
function scorePassword(pass) {
var score = 0;
if (!pass)
return score;
// award every unique letter until 5 repetitions
var letters = new Object();
for (var i=0; i<pass.length; i++) {
letters[pass[i]] = (letters[pass[i]] || 0) + 1;
score += 5.0 / letters[pass[i]];
}
// bonus points for mixing it up
var variations = {
digits: /\d/.test(pass),
lower: /[a-z]/.test(pass),
upper: /[A-Z]/.test(pass),
nonWords: /\W/.test(pass),
}
var variationCount = 0;
for (var check in variations) {
variationCount += (variations[check] == true) ? 1 : 0;
}
score += (variationCount - 1) * 10;
return parseInt(score);
}
Good passwords start to score around 60 or so, here's function to translate that in words:
function checkPassStrength(pass) {
var score = scorePassword(pass);
if (score > 80)
return "strong";
if (score > 60)
return "good";
if (score >= 30)
return "weak";
return "";
}
you might want to tune this a bit but i found it working for me nicely

What is the potential damage if it was possible to invoke
wait()
outside a synchronized block, retaining it's semantics - suspending the caller thread?
Let's illustrate what issues we would run into if wait()
could be called outside of a synchronized block with a concrete example.
Suppose we were to implement a blocking queue (I know, there is already one in the API :)
A first attempt (without synchronization) could look something along the lines below
class BlockingQueue {
Queue<String> buffer = new LinkedList<String>();
public void give(String data) {
buffer.add(data);
notify(); // Since someone may be waiting in take!
}
public String take() throws InterruptedException {
while (buffer.isEmpty()) // don't use "if" due to spurious wakeups.
wait();
return buffer.remove();
}
}
This is what could potentially happen:
A consumer thread calls take()
and sees that the buffer.isEmpty()
.
Before the consumer thread goes on to call wait()
, a producer thread comes along and invokes a full give()
, that is, buffer.add(data); notify();
The consumer thread will now call wait()
(and miss the notify()
that was just called).
If unlucky, the producer thread won't produce more give()
as a result of the fact that the consumer thread never wakes up, and we have a dead-lock.
Once you understand the issue, the solution is obvious: Use synchronized
to make sure notify
is never called between isEmpty
and wait
.
Without going into details: This synchronization issue is universal. As Michael Borgwardt points out, wait/notify is all about communication between threads, so you'll always end up with a race condition similar to the one described above. This is why the "only wait inside synchronized" rule is enforced.
A paragraph from the link posted by @Willie summarizes it quite well:
You need an absolute guarantee that the waiter and the notifier agree about the state of the predicate. The waiter checks the state of the predicate at some point slightly BEFORE it goes to sleep, but it depends for correctness on the predicate being true WHEN it goes to sleep. There's a period of vulnerability between those two events, which can break the program.
The predicate that the producer and consumer need to agree upon is in the above example buffer.isEmpty()
. And the agreement is resolved by ensuring that the wait and notify are performed in synchronized
blocks.
This post has been rewritten as an article here: Java: Why wait must be called in a synchronized block
You could try the "Microsoft Date and Time Picker Control". To use it, in the Toolbox, you right-click and choose "Additional Controls...". Then you check "Microsoft Date and Time Picker Control 6.0" and OK. You will have a new control in the Toolbox to do what you need.
I just found some printscreen of this on : http://www.logicwurks.com/CodeExamplePages/EDatePickerControl.html Forget the procedures, just check the printscreens.
May help you.
This will solve you problem.

Create a .o file:
g++ -c header.cpp
add this file to a library, creating library if necessary:
ar rvs header.a header.o
use library:
g++ main.cpp header.a
It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)
Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.
Here's another benchmark inspired by this gist. It compares concatenation (+
), appending (<<
) and interpolation (#{}
) for dynamic and predefined strings.
require 'benchmark'
# we will need the CAPTION and FORMAT constants:
include Benchmark
count = 100_000
puts "Dynamic strings"
Benchmark.benchmark(CAPTION, 7, FORMAT) do |bm|
bm.report("concat") { count.times { 11.to_s + '/' + 12.to_s } }
bm.report("append") { count.times { 11.to_s << '/' << 12.to_s } }
bm.report("interp") { count.times { "#{11}/#{12}" } }
end
puts "\nPredefined strings"
s11 = "11"
s12 = "12"
Benchmark.benchmark(CAPTION, 7, FORMAT) do |bm|
bm.report("concat") { count.times { s11 + '/' + s12 } }
bm.report("append") { count.times { s11 << '/' << s12 } }
bm.report("interp") { count.times { "#{s11}/#{s12}" } }
end
output:
Dynamic strings
user system total real
concat 0.050000 0.000000 0.050000 ( 0.047770)
append 0.040000 0.000000 0.040000 ( 0.042724)
interp 0.050000 0.000000 0.050000 ( 0.051736)
Predefined strings
user system total real
concat 0.030000 0.000000 0.030000 ( 0.024888)
append 0.020000 0.000000 0.020000 ( 0.023373)
interp 3.160000 0.160000 3.320000 ( 3.311253)
Conclusion: interpolation in MRI is heavy.
