To find "javaw.exe" in windows I would use (using batch)
for /f tokens^=2^ delims^=^" %%i in ('reg query HKEY_CLASSES_ROOT\jarfile\shell\open\command /ve') do set JAVAW_PATH=%%i
It should work in Windows XP and Seven, for JRE 1.6 and 1.7. Should catch the latest installed version.
java.exe is associated with the console, whereas javaw.exe doesn't have any such association. So, when java.exe is run, it automatically opens a command prompt window where output and error streams are shown.
The difference is in the subsystem that each executable targets.
java.exe
targets the CONSOLE
subsystem.javaw.exe
targets the WINDOWS
subsystem.We can select required fields over values.
Employee.objects.all().values('eng_name','rank')
random.uniform(a, b)
appears to be what your looking for. From the docs:
Return a random floating point number N such that a <= N <= b for a <= b and b <= N <= a for b < a.

Create jasper report in multiple languages(Unicode)
1)Install font in ireport desginer
2)create extension of font(we will use it in applications classpath)
3)install font on os(optional)
4)paste all .ttf of font in jre->lib->fonts directory (otherwise web application will throw error font is not available to JVM)
Just in case someone is looking for user Display Name as opposed to User Name, like me.
Here's the treat :

Found this post on a Google search, and it solved my issue thanks to @jwal reply, but I made one addition to his solution.
img.content.x700 {
width: auto !important; /*override the width below*/
width: 100%;
max-width: 678px;
float: left;
clear: both;
}
With the above I changed the max-width to the dimensions of the content container that my image is in. In this case it is: container width - padding - boarder = max width
This way my image won't break out of the containing div, and I can still float the image within the content div.
I've tested in IE 9, FireFox 18.0.2 and Chrome 25.0.1364.97, Safari iOS and seems to work.
Additional: I tested this on an image 1024px wide displayed at 678px (the max width), and an image 500px wide displayed at 500px (width of the image).
With Swift 5 this is what, worked for me!!
Step 1. Created IBOutlet for UIButton in My CustomCell.swift
class ListProductCell: UITableViewCell {
@IBOutlet weak var productMapButton: UIButton!
//todo
}
Step 2. Added action method in CellForRowAtIndex method and provided method implementation in the same view controller
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ListProductCell") as! ListProductCell
cell.productMapButton.addTarget(self, action: #selector(ListViewController.onClickedMapButton(_:)), for: .touchUpInside)
return cell
}
@objc func onClickedMapButton(_ sender: Any?) {

You cannot use both -jar
and -cp
on the command line - see the java documentation that says that if you use -jar
:
the JAR file is the source of all user classes, and other user class path settings are ignored.
You could do something like this:
java -cp lib\*.jar;. myproject.MainClass
Notice the ;.
in the -cp
argument, to work around a Java command-line bug. Also, please note that this is the Windows version of the command. The path separator on Unix is :
.
function setPixel(imageData, x, y, r, g, b, a) {
var index = 4 * (x + y * imageData.width);
imageData.data[index+0] = r;
imageData.data[index+1] = g;
imageData.data[index+2] = b;
imageData.data[index+3] = a;
}
grep -E -o ".{0,5}test_pattern.{0,5}" test.txt
This will match up to 5 characters before and after your pattern. The -o switch tells grep to only show the match and -E to use an extended regular expression. Make sure to put the quotes around your expression, else it might be interpreted by the shell.
Try this in your model:
function order_summary_insert()
$OrderLines=$this->input->post('orderlines');
$CustomerName=$this->input->post('customer');
$data = array(
'OrderLines'=>$OrderLines,
'CustomerName'=>$CustomerName
);
$this->db->insert('Customer_Orders',$data);
}
Try to use controller just to control the view and models always post your values in model. it makes easy to understand. Your controller will be:
function new_blank_order_summary() {
$this->sales_model->order_summary_insert($data);
$this->load->view('sales/new_blank_order_summary');
}
With Android's Newer Version >= API 16 use finishAffinity()
approach is suitable for >= API 16.
Intent mIntent = new Intent(mContext,MainActivity.class);
finishAffinity();
startActivity(mIntent);
Try to use DateTime.ParseExact method, in which you can specify both of datetime mask and original parsed string. You can read about it here: MSDN: DateTime.ParseExact
I have created the following, and it's working on my system. Please try this:
package.json:
{
"name": "test app",
"version": "1.0.0",
"scripts": {
"start": "node script1.js"
}
}
script1.js:
console.log('testing')
From your command line run the following command:
npm start
Additional use case
My package.json file has generally the following scripts, which enable me to watch my files for typescript, sass compilations and running a server as well.
"scripts": {
"start": "concurrently \"sass --watch ./style/sass:./style/css\" \"npm run tsc:w\" \"npm run lite\" ",
"tsc": "tsc",
"tsc:w": "tsc -w",
"lite": "lite-server",
"typings": "typings",
"postinstall": "typings install"
}
below works for mysql
update table1 INNER JOIN table2 on table1.col1 = table2.col1
set table1.col1 = table2.col2
The following is the correct overload (in your example you are missing a closing }
to the routeValues
anonymous object so your code will throw an exception):
<a href="<%: Url.Action("GetByList", "Listing", new { name = "John", contact = "calgary, vancouver" }) %>">
<span>People</span>
</a>
Assuming you are using the default routes this should generate the following markup:
<a href="/Listing/GetByList?name=John&contact=calgary%2C%20vancouver">
<span>People</span>
</a>
which will successfully invoke the GetByList
controller action passing the two parameters:
public ActionResult GetByList(string name, string contact)
{
...
}
Yes you can. The default location for script files is data/db
If you put any script there you can call it as
load("myjstest.js") // or
load("/data/db/myjstest.js")
Add the parameter declaration at the top of ps1 file
param(
# Our preferred encoding

)
write ("Encoding : {0}" -f $Encoding)
C:\temp> .\test.ps1 -Encoding ASCII

I found some answers, but I don't know if it is the right way.This is my solution for now. Fortunatelly it didn´t broke my design mode.

// do something with the return value ret
To add to Oleg's answer:
I was able to find the DLL at runtime by appending Visual Studio's $(ExecutablePath)
to the PATH environment variable in Configuration Properties->Debugging. This macro is exactly what's defined in the Configuration Properties->VC++ Directories->Executable Directories field*, so if you have that setup to point to any DLLs you need, simply adding this to your PATH makes finding the DLLs at runtime easy!
* I actually don't know if the $(ExecutablePath)
macro uses the project's Executable Directories setting or the global Property Pages' Executable Directories setting. Since I have all of my libraries that I often use configured through the Property Pages, these directories show up as defaults for any new projects I create.
Multi-node harnesses all the cores that you may have.
Have a look at http://github.com/kriszyp/multi-node.
For simpler needs, you can start up multiple copies of node on different port numbers and put a load balancer in front of them.
With this command you will see all changes in the repository path/to/repo
that were committed in revision <revision>
:
svn diff -c <revision> path/to/repo
The -c
indicates that you would like to look at a changeset, but there are many other ways you can look at diffs and changesets. For example, if you would like to know which files were changed (but not how), you can issue
svn log -v -r <revision>
Or, if you would like to show at the changes between two revisions (and not just for one commit):
svn diff -r <revA>:<revB> path/to/repo
If you use OmniFaces you can also use it's EL functions like of:formatDate()
to format Date
objects. You would use it like this:
<h:outputText value="#{of:formatDate(someBean.dateField, 'dd.MM.yyyy HH:mm')}" />
This way you can not only use it for output but also to pass it on to other JSF components.
There is the possibility of making something really more cool!

If you go to your android-sdk/tools
folder I think you'll find a message :
The adb tool has moved to platform-tools/
If you don't see this directory in your SDK, launch the SDK and AVD Manager (execute the android tool) and install "Android SDK Platform-tools"
Please also update your PATH environment variable to include the platform-tools/ directory, so you can execute adb from any location.
So you should also add C:/android-sdk/platform-tools
to you environment path. Also after you modify the PATH
variable make sure that you start a new CommandPrompt
window.
Most of the cases issue is due to problem with hostname . Please check the hostname ,some times database team will maintain many hostname for connecting same database . Please check with database team regarding this connection issue.
You can use partition or chunks function from funcy library:
from funcy import partition
for a, b, c, d in partition(4, ints):
foo += a * b * c * d
These functions also has iterator versions ipartition
and ichunks
, which will be more efficient in this case.
You can also peek at their implementation.
If that's your exact format, you can go through the list and modify the dictionaries.
for item in list_of_dicts:
for key, value in item.iteritems():
try:
item[key] = int(value)
except ValueError:
item[key] = float(value)
If you've got something more general, then you'll have to do some kind of recursive update on the dictionary. Check if the element is a dictionary, if it is, use the recursive update. If it's able to be converted into a float or int, convert it and modify the value in the dictionary. There's no built-in function for this and it can be quite ugly (and non-pythonic since it usually requires calling isinstance).
Several consequences result from this difference between AWT and Swing.
AWT is a thin layer of code on top of the OS, whereas Swing is much larger. Swing also has very much richer functionality. Using AWT, you have to implement a lot of things yourself, while Swing has them built in. For GUI-intensive work, AWT feels very primitive to work with compared to Swing. Because Swing implements GUI functionality itself rather than relying on the host OS, it can offer a richer environment on all platforms Java runs on. AWT is more limited in supplying the same functionality on all platforms because not all platforms implement the same-looking controls in the same ways.
Swing components are called "lightweight" because they do not require a
native OS object to implement their functionality. JDialog
and JFrame
are
heavyweight, because they do have a peer. So components like JButton
,
JTextArea
, etc., are lightweight because they do not have an OS peer.
A peer is a widget provided by the operating system, such as a button object or an entry field object.
Consider using Regular Expressions or FTP Globbing. By that you could start wget multiple times with different groups of filename starting characters depending on their frequency of occurrence.
This is for example how I sync a folder between two NAS:
wget --recursive --level 0 --no-host-directories --cut-dirs=2 --no-verbose --timestamping --backups=0 --bind-address=10.0.0.10 --user=<ftp_user> --password=<ftp_password> "ftp://10.0.0.100/foo/bar/[0-9a-hA-H]*" --directory-prefix=/volume1/foo &
wget --recursive --level 0 --no-host-directories --cut-dirs=2 --no-verbose --timestamping --backups=0 --bind-address=10.0.0.11 --user=<ftp_user> --password=<ftp_password> "ftp://10.0.0.100/foo/bar/[!0-9a-hA-H]*" --directory-prefix=/volume1/foo &
The first wget syncs all files/folders starting with 0, 1, 2... F, G, H
and the second thread syncs everything else.
This was the easiest way to sync between a NAS with one 10G ethernet port (10.0.0.100) and a NAS with two 1G ethernet ports (10.0.0.10 and 10.0.0.11). I bound the two wget threads through --bind-address
to the different ethernet ports and called them parallel by putting &
at the end of each line. By that I was able to copy huge files with 2x 100 MB/s = 200 MB/s in total.
The extensions available for each version of Postgresql vary. An easy way to check which extensions are available is, as has been already mentioned:
SELECT * FROM pg_available_extensions;
If the extension that you are looking for is available, you can install it using:
CREATE EXTENSION 'extensionName';
or if you want to drop it use:
DROP EXTENSION 'extensionName';
With psql
you can additionally check if the extension has been successfully installed using \dx
, and find more details about the extension using \dx+ extensioName
. It returns additional information about the extension, like which packages are used with it.
If the extension is not available in your Postgres version, then you need to download the necessary binary files and libraries and locate it them at /usr/share/conrib
It usually happens when Allow Nulls option is unchecked.
Solution:
Try these steps. It worked for me.
What I did is make sure that all in-app activities are launched with startActivityForResult
then checking if onActivityResult was called before onResume. If it wasn't, it means we just returned from somewhere outside our app.
boolean onActivityResultCalledBeforeOnResume;
@Override
public void startActivity(Intent intent) {
startActivityForResult(intent, 0);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
onActivityResultCalledBeforeOnResume = true;
}
@Override
protected void onResume() {
super.onResume();
if (!onActivityResultCalledBeforeOnResume) {
// here, app was brought to foreground
}
onActivityResultCalledBeforeOnResume = false;
}
Turns out I was doing it wrong, I needed to perform a nested select first of just the important columns, and do a distinct select off that to prevent trash columns of 'unique' data from corrupting my good data. The following appears to have resolved the issue... but I will try on the full dataset later.
SELECT DISTINCT P2.*
FROM (
SELECT
IDNo
, FirstName
, LastName
FROM people P
) P2
Here is some play data as requested: http://sqlfiddle.com/#!3/050e0d/3
CREATE TABLE people
(
[entry] int
, [IDNo] varchar(3)
, [FirstName] varchar(5)
, [LastName] varchar(7)
);
INSERT INTO people
(entry,[IDNo], [FirstName], [LastName])
VALUES
(1,'uqx', 'bob', 'smith'),
(2,'abc', 'john', 'willis'),
(3,'ABC', 'john', 'willis'),
(4,'aBc', 'john', 'willis'),
(5,'WTF', 'jeff', 'bridges'),
(6,'Sss', 'bill', 'doe'),
(7,'sSs', 'bill', 'doe'),
(8,'ssS', 'bill', 'doe'),
(9,'ere', 'sally', 'abby'),
(10,'wtf', 'jeff', 'bridges')
;
FYI, it looks like the syntax for retrieving the values has changed according to:
http://freemarker.sourceforge.net/docs/ref_builtins_hash.html
<#assign h = {"name":"mouse", "price":50}>
<#assign keys = h?keys>
<#list keys as key>${key} = ${h[key]}; </#list>
cmake's ExternalProject_Add
indeed can used, but what I did not like about it - is that it performs something during build, continuous poll, etc... I would prefer to build project during build phase, nothing else. I have tried to override ExternalProject_Add
in several attempts, unfortunately without success.
Then I have tried also to add git submodule, but that drags whole git repository, while in certain cases I need only subset of whole git repository. What I have checked - it's indeed possible to perform sparse git checkout, but that require separate function, which I wrote below.
#-----------------------------------------------------------------------------

#

#-----------------------------------------------------------------------------
function (SparseGitCheckout checkoutDir url branch)
if(EXISTS ${checkoutDir})
return()
endif()
message("-------------------------------------------------------------------")
message("sparse git checkout to ${checkoutDir}...")
message("-------------------------------------------------------------------")
file(MAKE_DIRECTORY ${checkoutDir})
set(cmds "git init")
set(cmds ${cmds} "git remote add -f origin --no-tags -t master ${url}")
set(cmds ${cmds} "git config core.sparseCheckout true")
# This command is executed via file WRITE

endif()

RESULT_VARIABLE ret
)
if(NOT ret EQUAL "0")
message("error: previous command failed, see explanation above")

I have added two function calls below just to illustrate how to use the function.
Someone might not like to checkout master / trunk, as that one might be broken - then it's always possible to specify specific tag.
Checkout will be performed only once, until you clear the cache folder.

My solution was to use global session helper: session()
Its functionality is a little bit harder than $request->session().
writing:
session(['key'=>'value']);
pushing:
session()->push('key', $notification);
retrieving:
session('key');
You can truncate all information after the month using date_trunc(text, timestamp)
:
select date_trunc('month',created_at)::date as date
from orders
order by date DESC;
created_at = '2019-12-16 18:28:13'
Output 1:
date_trunc('day',created_at)
// 2019-12-16 00:00:00
Output 2:
date_trunc('day',created_at)::date
// 2019-12-16
Output 3:
date_trunc('month',created_at)::date
// 2019-12-01
Output 4:
date_trunc('year',created_at)::date
// 2019-01-01
You can use rebase, for instance, git rebase our-team
when you are on your branch featurex
It will move the start point of the branch at the end of your our-team
branch, merging all changes in your featurex
branch.
Using display:inline-block

It looks like this error 0xe0434352 applies to a number of different errors.
In case it helps anyone, I ran into this error when I was trying to install my application on a new Windows 10 installation. It worked on other machines, and looked like the app momentarily would start before dying. After much trial and error the problem turned out to be that the app required DirectX9. Though a later version of DirectX was present it had to have version 9. Hope that saves someone some frustration.
I see the other one is closed. So basically here's the rough of my code. I think you are missing the string cmd comment. For example if my store procedure is call:DBO.Test. I would need to write cmd="DBO.test". Then do command type equal to store procedure, and blah blah blah
Connection.open();
String cmd="DBO.test"; //the command
Sqlcommand mycommand;
using angularjs:
$timeout(function(){
if(yourvariable===-1){
doSomeThingAfter5Seconds();
}
},5000)
The basic difference is that undefined
and null
represent different concepts.
If only null
was available, you would not be able to determine whether null
was set intentionally as the value or whether the value has not been set yet unless you used cumbersome error catching: eg
var a;
a == null; // This is true
a == undefined; // This is true;
a === undefined; // This is true;
However, if you intentionally set the value to null
, strict equality with undefined
fails, thereby allowing you to differentiate between null
and undefined
values:
var b = null;
b == null; // This is true
b == undefined; // This is true;
b === undefined; // This is false;
Check out the reference here instead of relying on people dismissively saying junk like "In summary, undefined is a JavaScript-specific mess, which confuses everyone". Just because you are confused, it does not mean that it is a mess.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/undefined
This behaviour is also not specific to JavaScript and it completes the generalised concept that a boolean result can be true
, false
, unknown (null
), no value (undefined
), or something went wrong (error
).
To keep images from stretching in either axis inside a flex parent I have found a couple of solutions.
You can try using object-fit on the image which, e.g.
object-fit: contain;
Or you can add flex-specfic rules which may work better in some cases.
align-self: center;
flex: 0 0 auto;
.blur-bgimage {
overflow: hidden;
margin: 0;
text-align: left;
}
.blur-bgimage:before {
content: "";
position: absolute;
width : 100%;
height: 100%;
background: inherit;
z-index: -1;
filter : blur(10px);
-moz-filter : blur(10px);
-webkit-filter: blur(10px);
-o-filter : blur(10px);
transition : all 2s linear;
-moz-transition : all 2s linear;
-webkit-transition: all 2s linear;
-o-transition : all 2s linear;
}
You can blur the body background image by using the body's :before pseudo class to inherit the image and then blurring it. Wrap all that into a class and use javascript to add and remove the class to blur and unblur.
On 2015-09-25 (after Xcode updates on 2015-09-18):

It might be a little insecure, but I couldn't find other solutions.
(A "bit" late, but this hasn't been mentioned at all)
You didn't specify your DBMS.
In standard SQL (and most modern DBMS like Oracle, PostgreSQL, DB2, Firebird, Apache Derby, HSQLDB and H2) you can specify NULLS LAST
or NULLS FIRST
:
Use NULLS LAST
to sort them to the end:
select *
from some_table
order by some_column DESC NULLS LAST
ps -ef | grep KEYWORD | grep -v grep | awk '{print $2}'
You have to catch the SIGINT signal (we are talking POSIX right?)
See @Gab Royer´s answer for sigaction.
Example:
#include <signal.h>
#include <stdlib.h>
#include <stdio.h>
void my_handler(sig_t s){
printf("Caught signal %d\n",s);
exit(1);
}
int main(int argc,char** argv)
{
signal (SIGINT,my_handler);
while(1);
return 0;
}
1) If your HTML markup is:
<input type="checkbox" />
attr used:
$(element).attr("checked"); // Will give you undefined as initial value of checkbox is not set
If prop is used:
$(element).prop("checked"); // Will give you false whether or not initial value is set
2) If your HTML markup is:
<input type="checkbox" checked="checked" />// May be like this also checked="true"
attr used:
$(element).attr("checked") // Will return checked whether it is checked="true"
Prop used:
$(element).prop("checked") // Will return true whether checked="checked"
Using ddl.Items.Clear()
will clear the dropdownlist however you must be sure that your dropdownlist is not set to:
AppendDataBoundItems="True"
This option will cause the rebound data to be appended to the existing list which will NOT be cleared prior to binding.
SOLUTION
Add AppendDataBoundItems="False"
to your dropdownlist.
Now when data is rebound it will automatically clear all existing data beforehand.
Protected Sub ddl1_SelectedIndexChanged(sender As Object, e As EventArgs)
ddl2.DataSource = sql2
ddl2.DataBind()
End Sub
NOTE: This may not be suitable in all situations as appenddatbound items can cause your dropdown to append its own data on each change of the list.
TOP TIP
Still want a default list item adding to your dropdown but need to rebind data?
Use AppendDataBoundItems="False"
to prevent duplication data on postback and then directly after binding your dropdownlist insert a new default list item.
ddl.Items.Insert(0, New ListItem("Select ...", ""))
Use String#next
as the counter.
>> n = "000"
>> 3.times { puts "file_#{n.next!}" }
file_001
file_002
file_003
next
is relatively 'clever', meaning you can even go for
>> n = "file_000"
>> 3.times { puts n.next! }
file_001
file_002
file_003
If you want to add a product into the array you can use:
$item['product'] = $product;
Solutions using value.toUpperCase seem to have the problem that typing text into the field resets the cursor position to the end of the text. Solutions using text-transform seem to have the problem that the text submitted to the server is still potentially lowercase. This solution avoids those problems:
function handleInput(e) {_x000D_
var ss = e.target.selectionStart;_x000D_
var se = e.target.selectionEnd;_x000D_
e.target.value = e.target.value.toUpperCase();_x000D_
e.target.selectionStart = ss;_x000D_
e.target.selectionEnd = se;_x000D_
}
_x000D_
<input type="text" id="txtTest" oninput="handleInput(event)" />
_x000D_
In Jan2018 the only solution worked for me:
<?php
if (ob_get_level() == 0) ob_start();
for ($i = 0; $i<10; $i++){
echo "<br> Line to show.";
echo str_pad('',4096)."\n";
ob_flush();
flush();
sleep(2);
}
echo "Done.";
ob_end_flush();
?>
Views are essentially logical table-like structures populated on the fly by a given query. The results of a view query are not stored anywhere on disk and the view is recreated every time the query is executed. Materialized views are actual structures stored within the database and written to disk. They are updated based on the parameters defined when they are created.
If you are running Windows 7 64-bit, I would strongly suggest you download the 64-bit Java installer. There is no sense in downloading the x86 installer on an x64 based OS.
That corrected the problem for me.
GRANT
s on different objects are separate. GRANT
ing on a database doesn't GRANT
rights to the schema within. Similiarly, GRANT
ing on a schema doesn't grant rights on the tables within.
If you have rights to SELECT
from a table, but not the right to see it in the schema that contains it then you can't access the table.
The rights tests are done in order:
Do you have `USAGE` on the schema?
No: Reject access.
Yes: Do you also have the appropriate rights on the table?
No: Reject access.
Yes: Check column privileges.
Your confusion may arise from the fact that the public
schema has a default GRANT
of all rights to the role public
, which every user/group is a member of. So everyone already has usage on that schema.
The phrase:
(assuming that the objects' own privilege requirements are also met)
Is saying that you must have USAGE
on a schema to use objects within it, but having USAGE
on a schema is not by itself sufficient to use the objects within the schema, you must also have rights on the objects themselves.
It's like a directory tree. If you create a directory somedir
with file somefile
within it then set it so that only your own user can access the directory or the file (mode rwx------
on the dir, mode rw-------
on the file) then nobody else can list the directory to see that the file exists.
If you were to grant world-read rights on the file (mode rw-r--r--
) but not change the directory permissions it'd make no difference. Nobody could see the file in order to read it, because they don't have the rights to list the directory.
If you instead set rwx-r-xr-x
on the directory, setting it so people can list and traverse the directory but not changing the file permissions, people could list the file but could not read it because they'd have no access to the file.
You need to set both permissions for people to actually be able to view the file.
Same thing in Pg. You need both schema USAGE
rights and object rights to perform an action on an object, like SELECT
from a table.
(The analogy falls down a bit in that PostgreSQL doesn't have row-level security yet, so the user can still "see" that the table exists in the schema by SELECT
ing from pg_class
directly. They can't interact with it in any way, though, so it's just the "list" part that isn't quite the same.)
The most important things POSIX 7 defines
Greatly extends ANSI C with things like:
mkdir
, dirname
, symlink
, readlink
, link
(hardlinks), poll()
, stat
, sync
, nftw()
fork
, execl
, wait
, pipe
, semaphors sem_*
, shared memory (shm_*
), kill
, scheduling parameters (nice
, sched_*
), sleep
, mkfifo
, setpgid()
socket()
mmap
, mlock
, mprotect
, madvise
, brk()
reg*
)Those APIs also determine underlying system concepts on which they depend, e.g. fork
requires a concept of a process.
Many Linux system calls exist to implement a specific POSIX C API function and make Linux compliant, e.g. sys_write
, sys_read
, ... Many of those syscalls also have Linux-specific extensions however.
Major Linux desktop implementation: glibc, which in many cases just provides a shallow wrapper to system calls.
E.g.: cd
, ls
, echo
, ...
Many utilities are direct shell front ends for a corresponding C API function, e.g. mkdir
.
Major Linux desktop implementation: GNU Coreutils for the small ones, separate GNU projects for the big ones: sed
, grep
, awk
, ... Some CLI utilities are implemented by Bash as built-ins.
E.g., a=b; echo "$a"
Major Linux desktop implementation: GNU Bash.
E.g.: HOME
, PATH
.
PATH
search semantics are specified, including how slashes prevent PATH
search.
ANSI C says 0
or EXIT_SUCCESS
for success, EXIT_FAILURE
for failure, and leaves the rest implementation defined.
POSIX adds:
126
: command found but not executable.
127
: command not found.
> 128
: terminated by a signal.
But POSIX does not seem to specify the 128 + SIGNAL_ID
rule used by Bash: https://unix.stackexchange.com/questions/99112/default-exit-code-when-process-is-terminated
There are two types: BRE (Basic) and ERE (Extended). Basic is deprecated and only kept to not break APIs.
Those are implemented by C API functions, and used throughout CLI utilities, e.g. grep
accepts BREs by default, and EREs with -E
.
E.g.: echo 'a.1' | grep -E 'a.[[:digit:]]'
Major Linux implementation: glibc implements the functions under regex.h which programs like grep
can use as backend.
E.g.: /dev/null
, /tmp
The Linux FHS greatly extends POSIX.
/

, ..
parenta-zA-Z0-9._-
See also: what is posix compliance for filesystem?
Command line utility API conventions
Not mandatory, used by POSIX, but almost nowhere else, notably not in GNU. But true, it is too restrictive, e.g. single letter flags only (e.g. -a
), no double hyphen long versions (e.g. --all
).
A few widely used conventions:
-
means stdin where a file is expected--
terminates flags, e.g. ls -- -l
to list a directory named -l
See also: Are there standards for Linux command line switches and arguments?
"POSIX ACLs" (Access Control Lists), e.g. as used as backend for setfacl
.
This was withdrawn but it was implemented in several OSes, including in Linux with setxattr
.
Who conforms to POSIX?
Many systems follow POSIX closely, but few are actually certified by the Open Group which maintains the standard. Notable certified ones include:
Most Linux distros are very compliant, but not certified because they don't want to pay the compliance check. Inspur's K-UX and Huawei's EulerOS are two certified examples.
The official list of certified systems be found at: https://www.opengroup.org/openbrand/register/ and also at the wiki page.
Windows
Windows implemented POSIX on some of its professional distributions.
Since it was an optional feature, programmers could not rely on it for most end user applications.
Support was deprecated in Windows 8:
In 2016 a new official Linux-like API called "Windows Subsystem for Linux" was announced. It includes Linux system calls, ELF running, parts of the /proc
filesystem, Bash, GCC, (TODO likely glibc?), apt-get
and more: https://channel9.msdn.com/Events/Build/2016/P488 so I believe that it will allow Windows to run much, if not all, of POSIX. However, it is focused on developers / deployment instead of end users. In particular, there were no plans to allow access to the Windows GUI.
Historical overview of the official Microsoft POSIX compatibility: http://brianreiter.org/2010/08/24/the-sad-history-of-the-microsoft-posix-subsystem/
Cygwin is a well known GPL third-party project for that "provides substantial POSIX API functionality" for Windows, but requires that you "rebuild your application from source if you want it to run on Windows". MSYS2 is a related project that seems to add more functionality on top of Cygwin.
Android
Android has its own C library (Bionic) which does not fully support POSIX as of Android O: Is Android POSIX-compatible?
Bonus level
The Linux Standard Base further extends POSIX.

Reproducing my answer from this thread which was more specific to setting beyond compare as diff tool for Git. All the details that I've shared are equally useful for any diff tool in general so sharing it here:
The first command that we run is as below:
git config --global diff.tool bc3
The above command creates below entry in .gitconfig
found in %userprofile%
directory:
[diff]
tool = bc3
Then you run below command (Running this command is redundant in this particular case and is required in some specialized cases only. You will know it in a short while):
git config --global difftool.bc3.path "c:/program files/beyond compare 3/bcomp.exe"
Above command creates below entry in .gitconfig
file:
[difftool "bc3"]
path = c:/program files/Beyond Compare 3/bcomp.exe
The thing to know here is the key bc3
. This is a well known key to git corresponding to a particular version of well known comparison tools available in market (bc3
corresponds to 3rd version of Beyond Compare tool). If you want to see all pre-defined keys just run git difftool --tool-help
command on git bash. It returns below list:
vimdiff
vimdiff2
vimdiff3
araxis
bc
bc3
codecompare
deltawalker
diffmerge
diffuse
ecmerge
emerge
examdiff
gvimdiff
gvimdiff2
gvimdiff3
kdiff3
kompare
meld
opendiff
p4merge
tkdiff
winmerge
xxdiff
You can use any of the above keys or define a custom key of your own. If you want to setup a new tool altogether(or a newly released version of well-known tool) which doesn't map to any of the keys listed above then you are free to map it to any of keys listed above or to a new custom key of your own.
What if you have to setup a comparison tool which is
OR
Like in my case, I had installed beyond compare 4. beyond compare is a well-known tool to git but its version 4 release is not mapped to any of the existing keys by default. So you can follow any of the below approaches:
I can map beyond compare 4 tool to already existing key bc3
which corresponds to beyond compare 3 version. I didn't have beyond compare version 3 on my computer so I didn't care. If I wanted I could have mapped it to any of the pre-defined keys in the above list also e.g. examdiff
.
If you map well known version of tools to appropriate already existing/well- known key then you would not need to run the second command as their install path is already known to git.
For e.g. if I had installed beyond compare version 3 on my box then having below configuration in my .gitconfig
file would have been sufficient to get going:
[diff]
tool = bc3
But if you want to change the default associated tool then you end up mentioning the path
attribute separately so that git gets to know the path from where you new tool's exe has to be launched. Here is the entry which foxes git to launch beyond compare 4 instead. Note the exe's path:
[difftool "bc3"]
path = c:/program files/Beyond Compare 4/bcomp.exe
Most cleanest approach is to define a new key altogether for the new comparison tool or a new version of an well known tool. Like in my case I defined a new key bc4
so that it is easy to remember. In such a case you have to run two commands in all but your second command will not be setting path of your new tool's executable. Instead you have to set cmd
attribute for your new tool as shown below:
git config --global diff.tool bc4
git config --global difftool.bc4.cmd "\"C:\\Program Files\\Beyond Compare 4\\bcomp.exe\" -s \"\$LOCAL\" -d \"\$REMOTE\""
Running above commands creates below entries in your .gitconfig
file:
[diff]
tool = bc4
[difftool "bc4"]
cmd = \"C:\\Program Files\\Beyond Compare 4\\bcomp.exe\" -s \"$LOCAL\" -d \"$REMOTE\"
I would strongly recommend you to follow approach # 2 to avoid any confusion for yourself in future.
Did you try just passing the string variable to a for
loop? Bash, for one, will split on whitespace automatically.

Here is how I handle it. It handles floating point numbers, but can easily be modified for integers.
Basically you can only press 0 - 9 and .
You can only have one 0 before the .
All other characters are ignored and the cursor position maintained.
private bool _myTextBoxChanging = false;
private void myTextBox_TextChanged(object sender, EventArgs e)
{
validateText(myTextBox);
}
private void validateText(TextBox box)
{
// stop multiple changes;
if (_myTextBoxChanging)
return;
_myTextBoxChanging = true;
string text = box.Text;
if (text == "")
return;
string validText = "";
bool hasPeriod = false;
int pos = box.SelectionStart;
for (int i = 0; i < text.Length; i++ )
{
bool badChar = false;
char s = text[i];
if (s == '.')
{
if (hasPeriod)
badChar = true;
else
hasPeriod = true;
}
else if (s < '0' || s > '9')
badChar = true;
if (!badChar)
validText += s;
else
{
if (i <= pos)
pos--;
}
}
// trim starting 00s
while (validText.Length >= 2 && validText[0] == '0')
{
if (validText[1] != '.')
{
validText = validText.Substring(1);
if (pos < 2)
pos--;
}
else
break;
}
if (pos > validText.Length)
pos = validText.Length;
box.Text = validText;
box.SelectionStart = pos;
_myTextBoxChanging = false;
}
Here is a quickly modified int version:
private void validateText(TextBox box)
{
// stop multiple changes;
if (_myTextBoxChanging)
return;
_myTextBoxChanging = true;
string text = box.Text;
if (text == "")
return;
string validText = "";
int pos = box.SelectionStart;
for (int i = 0; i < text.Length; i++ )
{
char s = text[i];
if (s < '0' || s > '9')
{
if (i <= pos)
pos--;
}
else
validText += s;
}
// trim starting 00s
while (validText.Length >= 2 && validText.StartsWith("00"))
{
validText = validText.Substring(1);
if (pos < 2)
pos--;
}
if (pos > validText.Length)
pos = validText.Length;
box.Text = validText;
box.SelectionStart = pos;
_myTextBoxChanging = false;

Adding one more answer for Windows users. If none of this solves the problems.
Do not add space
before or after =
-DgroupId= com.company.module //Wrong , Watch the space after the equal to
-DgroupId=com.company.module //Right
Its better to put everything inside double quotes, like "-DgroupId=com.." This will give you exact error rather than some random error.
Weird that , maven does not even care to mention this in the documentation.
I also ran into this problem, but the solution that seems to be a common thread here, and I saw elsewhere on the web, is "[re]install the redistributable package". However, for me that does not work, as the problem arose when running the installer for our product (which installs the redistributable package) to test our shiny new Visual Studio 2015 builds.
The issue came up because the DLL files listed are not located in the Visual Studio install path (for example, C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\redist) and thus had not been added to the install. These api-ms-win-* dlls get installed to a Windows 10 SDK install path as part of the Visual Studio 2015 install (e.g. C:\Program Files (x86)\Windows Kits\10\Redist).
Installing on Windows 10 worked fine, but installing on Windows 7 required adding these DLL files to our product install. For more information, see Update for Universal C Runtime in Windows which describes the addition of these dependencies caused by Visual Studio 2015 and provides downloads for various Windows platforms; also see Introducing the Universal CRT which describes the redesign of the CRT libraries. Of particular interest is item 6 under the section titled Distributing Software that uses the Universal CRT:
Updated September 11, 2015: App-local deployment of the Universal CRT is supported. To obtain the binaries for app-local deployment, install the Windows Software Development Kit (SDK) for Windows 10. The binaries will be installed to C:\Program Files (x86)\Windows Kits\10\Redist\ucrt. You will need to copy all of the DLLs with your app (note that the set of DLL files are necessary is different on different versions of Windows, so you must include all of the DLL files in order for your program to run on all supported versions of Windows).

If you are on a remote machine, you may also want to add the -f option to force the reboot. Otherwise your session may close and a stubborn app can hang the system.
I use this whenever I want to force an immediate reboot:
shutdown -t 0 -r -f
For a more friendly "give them some time" option, you can use this:
shutdown -t 30 -r
As you can see in the comments, the -f is implied by the timeout.
Brutus 2006 is a utility that provides a GUI for these options.

If the POM missing warning is of project's self module, the reason is that you are trying to mistakenly build from a sub-module directory. You need to run the build and install command from root directory of the project.
After having looked at various versions of itoa for gcc, the most flexible version I have found that is capable of handling conversions to binary, decimal and hexadecimal, both positive and negative is the fourth version found at http://www.strudel.org.uk/itoa/. While sprintf
/snprintf
have advantages, they will not handle negative numbers for anything other than decimal conversion. Since the link above is either off-line or no longer active, I've included their 4th version below:

if (base < 2 || base > 36) { *result = '\0'; return result; }
char* ptr = result, *ptr1 = result, tmp_char;
int tmp_value;
do {
tmp_value = value;
value /= base;
*ptr++ = "zyxwvutsrqponmlkjihgfedcba9876543210123456789abcdefghijklmnopqrstuvwxyz" [35 + (tmp_value - value * base)];

You're comparing the object references, and they are not the same. You need to compare the array contents.
An option is iterating through the array elements and call Equals()
for each element. Remember that you need to override the Equals()
method for the array elements, if they are not the same object reference.
An alternative is using this generic method to compare two generic arrays:
static bool ArraysEqual<T>(T[] a1, T[] a2)
{
if (ReferenceEquals(a1, a2))
return true;
if (a1 == null || a2 == null)
return false;
if (a1.Length != a2.Length)
return false;
var comparer = EqualityComparer<T>.Default;
for (int i = 0; i < a1.Length; i++)
{
if (!comparer.Equals(a1[i], a2[i])) return false;
}
return true;
}
Or use SequenceEqual if Linq is available for you (.NET Framework >= 3.5)
A real literal suffixed by M or m is of type decimal (money). For example, the literals 1m, 1.5m, 1e10m, and 123.456M are all of type decimal. This literal is converted to a decimal value by taking the exact value, and, if necessary, rounding to the nearest representable value using banker's rounding. Any scale apparent in the literal is preserved unless the value is rounded or the value is zero (in which latter case the sign and scale will be 0). Hence, the literal 2.900m will be parsed to form the decimal with sign 0, coefficient 2900, and scale 3.
You should code like this.
var num = $('#Number').val();
$('#Number').focus().val('').val(num);

You cannot "convert" an existing column into an IDENTITY
column - you will have to create a new column as INT IDENTITY
:
ALTER TABLE ProductInProduct
ADD NewId INT IDENTITY (1, 1);
Update:
OK, so there is a way of converting an existing column to IDENTITY
. If you absolutely need this - check out this response by Martin Smith with all the gory details.
You can simply go Netbeans, in the design view, go to JFrame
property, choose icon image property, Choose Set Form's iconImage
property using: "Custom code" and then in the Form.SetIconImage()
function put the following code:
Toolkit.getDefaultToolkit().getImage(name_of_your_JFrame.class.getResource("image.png"))
Do not forget to import:
import java.awt.Toolkit;
in the source code!
I was running into a similar error in pywikipediabot. The .decode
method is a step in the right direction but for me it didn't work without adding 'ignore'
:
ignore_encoding = lambda s: s.decode('utf8', 'ignore')
Ignoring encoding errors can lead to data loss or produce incorrect output. But if you just want to get it done and the details aren't very important this can be a good way to move faster.
It's a horribly obscure way to do a type conversion.
!
is NOT. So !true
is false
, and !false
is true
. !0
is true
, and !1
is false
.
So you're converting a value to a boolean, then inverting it, then inverting it again.
// Maximum Obscurity:
val.enabled = !!userId;
// Partial Obscurity:
val.enabled = (userId != 0) ? true : false;
// And finally, much easier to understand:
val.enabled = (userId != 0);
Got it! I found an idea here

In this example, they loaded a blank popup window into an object, cloned the contents of the element to be displayed, and appended it to the body of the object. Since I already knew what the contents of view-details (or any page I load in the lightbox), I just had to clone that content instead and load it into an object. Then, I just needed to print that object. The final outcome looks like this:
$('.printBtn').bind('click',function() {
var thePopup = window.open( '', "Customer Listing", "menubar=0,location=0,height=700,width=700" );
$('#popup-content').clone().appendTo( thePopup.document.body );
thePopup.print();
});
I had one small drawback in that the style sheet I was using in view-details.php was using a relative link. I had to change it to an absolute link. The reason being that the window didn't have a URL associated with it, so it had no relative position to draw on.
Works in Firefox. I need to test it in some other major browsers too.
I don't know how well this solution works when you're dealing with images, videos, or other process intensive solutions. Although, it works pretty well in my case, since I'm just loading tables and text values.
Thanks for the input! You gave me some ideas of how to get around this.
Even better, you do not need to create separate android xml layout for list cell view. You can just use "android.R.layout.simple_list_item_1" if the list only contains textview.
private class ExampleAdapter extends ArrayAdapter<String>{
public ExampleAdapter(Context context, int textViewResourceId, String[] objects) {
super(context, textViewResourceId, objects);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
TextView tv = (TextView) view.findViewById(android.R.id.text1);
tv.setTextColor(0);
return view;
}
Here is a "concrete" (and possibly useful) example of how, why, and when to use these handy, yet unsightly constructs...
Xcode uses a "global" "user default" to decide which XCTestObserver
class spews it's heart out to the beleaguered console.
In this example... when I implicitly load this psuedo-library, let's call it... libdemure.a
, via a flag in my test target á la..
OTHER_LDFLAGS = -ldemure
I want to..
At load (ie. when XCTest
loads my test bundle), override the "default" XCTest
"observer" class... (via the constructor
function) PS: As far as I can tell.. anything done here could be done with equivalent effect inside my class' + (void) load { ... }
method.
run my tests.... in this case, with less inane verbosity in the logs (implementation upon request)
Return the "global" XCTestObserver
class to it's pristine state.. so as not to foul up other XCTest
runs which haven't gotten on the bandwagon (aka. linked to libdemure.a
). I guess this historically was done in dealloc
.. but I'm not about to start messing with that old hag.
So...
#define USER_DEFS NSUserDefaults.standardUserDefaults
@interface DemureTestObserver : XCTestObserver @end
@implementation DemureTestObserver
__attribute__((constructor)) static void hijack_observer() {
/*! here I totally hijack the default logging, but you CAN
use multiple observers, just CSV them,
i.e. "@"DemureTestObserverm,XCTestLog"
*/
[USER_DEFS setObject:@"DemureTestObserver"
forKey:@"XCTestObserverClass"];
[USER_DEFS synchronize];
}
__attribute__((destructor)) static void reset_observer() {
// Clean up, and it's as if we had never been here.
[USER_DEFS setObject:@"XCTestLog"
forKey:@"XCTestObserverClass"];
[USER_DEFS synchronize];
}
...
@end
Without the linker flag... (Fashion-police swarm Cupertino demanding retribution, yet Apple's default prevails, as is desired, here)
WITH the -ldemure.a
linker flag... (Comprehensible results, gasp... "thanks constructor
/destructor
"... Crowd cheers)
When I write programs, during initialization, I usually spin off a thread for error handling, and initialize a special structure for errors, including a lock. Then, when I detect an error, through return values, I enter in the info from the exception into the structure and send a SIGIO to the exception handling thread, then see if I can't continue execution. If I can't, I send a SIGURG to the exception thread, which stops the program gracefully.
Just add a .
to it:
svn checkout file:///home/landonwinters/svn/waterproject/trunk .
That means: check out to current directory.
This can be done from the command line. This will create a column for your image with a NOT NULL
property.
CREATE TABLE `test`.`pic` (
`idpic` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
`caption` VARCHAR(45) NOT NULL,
`img` LONGBLOB NOT NULL,
PRIMARY KEY(`idpic`)
)
TYPE = InnoDB;
From here
I added the Context Menu item for Folders to open in Sublime Text. In windows, you can right click on any Folder and open the structure in Sublime. You could also create a service (?) for Mac OS - I'm just not familiar with the process.
The following could be saved to a File (OpenFolderWithSublime.reg) to merge to the registry. Be Sure to modify the directory structure to appropriately point to your Sublime installation. Alternatively, you can use REGEDIT and browse to HKCR\Folder\shell and create the values manually.
Windows Registry Editor Version 5.00

import org.apache.commons.io.IOUtils;
public class JsonParsing {
public static void main(String[] args) throws Exception {
InputStream is =
JsonParsing.class.getResourceAsStream( "sample-json.txt");
String jsonTxt = IOUtils.toString( is );
JSONObject json = (JSONObject) JSONSerializer.toJSON( jsonTxt );
double coolness = json.getDouble( "coolness" );
int altitude = json.getInt( "altitude" );
JSONObject pilot = json.getJSONObject("pilot");
String firstName = pilot.getString("firstName");
String lastName = pilot.getString("lastName");
System.out.println( "Coolness: " + coolness );
System.out.println( "Altitude: " + altitude );
System.out.println( "Pilot: " + lastName );
}
}
and this is your sample-json.txt , should be in json format

'foo':'bar',
'coolness':2.0,
'altitude':39000,
'pilot':
{
'firstName':'Buzz',
'lastName':'Aldrin'

Code Climber and this blog entry provide detailed ways of increasing application's performance.
Compiled query will increase performance of your application, but it has nothing in common with ASP.NET MVC. It will speed up every db application, so it is not really about MVC.
Try the top
command. It's an interactive command that will display the running processes.
You may also use the Apple's "Activity Monitor" application (located in /Applications/Utilities/
).
It provides an actually quite nice GUI. You can see all the running processes, filter them by users, get extended informations about them (CPU, memory, network, etc), monitor them, etc...
Probably your best choice, unless you want to stick with the terminal (in such a case, read the top
or ps
manual, as those commands have a bunch of options).
for those developers who came to this question about checking where they can return null from component instead of checking in ternary mode to render or not render the component, the answer is YES, You Can!
i mean instead of this junk ternary condition inside your jsx in render part of your component:
// some component body
return(
<section>
{/* some ui */}
{ someCondition && <MyComponent /> }
or
{ someCondition ? <MyComponent /> : null }
{/* more ui */}
</section>
)
you can check than condition inside your component like:
const MyComponent:React.FC = () => {
// get someCondition from context at here before any thing
if(someCondition) return null; // i mean this part , checking inside component!
return (
<section>
// some ui...
</section>
)
}
Just Consider that in my case i provide the someCondition
variable from a context in upper level component ( for example, just consider in your mind ) and i don't need to prop drill the someCondition
inside MyComponent
.
Just look how clean view your code gets after that, i mean you don't need to user ternary operator inside your JSX, and your parent component would like below:
// some component body
return(
<section>
{/* some ui */}
<MyComponent />
{/* more ui */}
</section>
)
and MyComponent
would handle the rest for you!
The root cause of IllegalStateException exception is a java servlet is attempting to write to the output stream (response) after the response has been committed.
It is always better to ensure that no content is added to the response after the forward or redirect is done to avoid IllegalStateException. It can be done by including a ‘return’ statement immediately next to the forward or redirect statement.
httpOnly is supported as of Tomcat 6.0.19 and Tomcat 5.5.28.
See the changelog entry for bug 44382.
The last comment for bug 44382 states, "this has been applied to 5.5.x and will be included in 5.5.28 onwards." However, it does not appear that 5.5.28 has been released.
The httpOnly functionality can be enabled for all webapps in conf/context.xml:
<Context useHttpOnly="true">
...
</Context>
My interpretation is that it also works for an individual context by setting it on the desired Context entry in conf/server.xml (in the same manner as above).
The SQL used in a PreparedStatement is precompiled on the driver. From that point on, the parameters are sent to the driver as literal values and not executable portions of SQL; thus no SQL can be injected using a parameter. Another beneficial side effect of PreparedStatements (precompilation + sending only parameters) is improved performance when running the statement multiple times even with different values for the parameters (assuming that the driver supports PreparedStatements) as the driver does not have to perform SQL parsing and compilation each time the parameters change.
You can try like this. It works for me
$("#MISSION_ID").select2();
On hide/show or ajax request, we have to reinitialize the select2 plugin
For example:
$("#offialNumberArea").show();
$("#eventNameArea").hide();
$('.selectCriteria').change(function(){
var thisVal = $(this).val();
if(thisVal == 'sailor'){
$("#offialNumberArea").show();
$("#eventNameArea").hide();
}
else
{
$("#offialNumberArea").hide();
$("#eventNameArea").show();
$("#MISSION_ID").select2();
}
});
Sorry to bother but erat2() has a serious flaw in the algorithm.
While searching for the next composite, we need to test odd numbers only. q,p both are odd; then q+p is even and doesn't need to be tested, but q+2*p is always odd. This eliminates the "if even" test in the while loop condition and saves about 30% of the runtime.
While we're at it: instead of the elegant 'D.pop(q,None)' get and delete method use 'if q in D: p=D[q],del D[q]' which is twice as fast! At least on my machine (P3-1Ghz). So I suggest this implementation of this clever algorithm:
def erat3( ):
from itertools import islice, count
# q is the running integer that's checked for primeness.
# yield 2 and no other even number thereafter
yield 2
D = {}
# no need to mark D[4] as we will test odd numbers only
for q in islice(count(3),0,None,2):
if q in D: # is composite
p = D[q]
del D[q]
# q is composite. p=D[q] is the first prime that
# divides it. Since we've reached q, we no longer
# need it in the map, but we'll mark the next
# multiple of its witnesses to prepare for larger
# numbers.
x = q + p+p # next odd(!) multiple
while x in D: # skip composites
x += p+p
D[x] = p
else: # is prime
# q is a new prime.
# Yield it and mark its first multiple that isn't
# already marked in previous iterations.
D[q*q] = q
yield q
Use this to find total count in resulting collection.
db.collection.aggregate( [
{ $match : { score : { $gt : 70, $lte : 90 } } },
{ $group: { _id: null, count: { $sum: 1 } } }
] );
If you want two classes on one element, do it this way:
<div class="social first"></div>
Reference it in css like so:
.social.first {}
Example:
You can make the whole script a function like this:
main_function() {
do_things_here
}
then at the end of the script have this:
if [ -z $TERM ]; then
# if not run via terminal, log everything into a log file
main_function 2>&1 >> /var/log/my_uber_script.log
else
# run via terminal, only output to screen
main_function
fi
Alternatively, you may log everything into logfile each run and still output it to stdout by simply doing:
# log everything, but also output to stdout
main_function 2>&1 | tee -a /var/log/my_uber_script.log
If none of the other solutions work for you, it's worth investigating the source of the problem. It may be than an npm module directly inserts ES6 code, which cannot be transpiled.
In my case I had the
SCRIPT1002: Syntax error vendor.js (114536,27) at the following line:
const ucs2encode = array => String.fromCodePoint(...array);
I searched the node_modules folder and found from which file the line came. It turned out that the culprit was punycode.js which in it's 2.1.0 version uses ES6 directly.
After I downgraded it to 1.4.1, which uses ES5, the problem was solved.
This is not about running a batch script as admin per, but rather how to elevate another program from batch...
I have a batch file "wrapper" for an exe. They have the same "root file name", but alternate extensions. I am able to launch the exe as admin, and set the working directory to the one containing the script, with the following one line powershell invocation:
@powershell "Start-Process -FilePath '%~n0.exe' -WorkingDirectory '%~dp0' -Verb RunAs"
There are a whole slew of additional Start-Process
options as well that you can apply! Check out: https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/start-process?view=powershell-6
Note that I use the @
prefix. That's equivalent to @echo off
for the one line. I use %~n0
here to get the "root name" of the batch script, then I concatenate the .exe
to point it the adjancent binary. The use of %~dp0
provides the full path to the directory which the batch resides. And, of course, the -Verb RunAs
parameter provides the elevation.
In my case it was the lockfile postmaster.id
that was not deleted properly during the last system crash that caused the issue. Deleting it with sudo rm /usr/local/var/postgres/postmaster.pid
and restarting Postgres solved the problem.
Since I have recently developed an Android application using gyroscope data (steady compass), I tried to collect a list with such devices. This is not an exhaustive list at all, but it is what I have so far:
*** Phones:
*** Tablets:
Hope the list keeps growing and hope that gyros will be soon available on mid and low price smartphones.
2 + 2 = 5(*)
(for some floating-precision values of 2)
This problem frequently arises when we think of"floating point" as a way to increase precision. Then we run afoul of the "floating" part, which means there is no guarantee of which numbers can be represented.
So while we might easily be able to represent "1.0, -1.0, 0.1, -0.1" as we get to larger numbers we start to see approximations - or we should, except we often hide them by truncating the numbers for display.
As a result, we might think the computer is storing "0.003" but it may instead be storing "0.0033333333334".
What happens if you perform "0.0003 - 0.0002"? We expect .0001, but the actual values being stored might be more like "0.00033" - "0.00029" which yields "0.000004", or the closest representable value, which might be 0, or it might be "0.000006".
With current floating point math operations, it is not guaranteed that (a / b) * b == a.
#include <stdio.h>
// defeat inline optimizations of 'a / b * b' to 'a'
extern double bodge(int base, int divisor) {
return static_cast<double>(base) / static_cast<double>(divisor);
}
int main() {
int errors = 0;
for (int b = 1; b < 100; ++b) {
for (int d = 1; d < 100; ++d) {
// b / d * d ... should == b
double res = bodge(b, d) * static_cast<double>(d);
// but it doesn't always
if (res != static_cast<double>(b))
++errors;
}
}
printf("errors: %d\n", errors);
}
ideone reports 599 instances where (b * d) / d != b using just the 10,000 combinations of 1 <= b <= 100 and 1 <= d <= 100 .
The solution described in the FAQ is essentially to apply a granularity constraint - to test if (a == b +/- epsilon)
.
An alternative approach is to avoid the problem entirely by using fixed point precision or by using your desired granularity as the base unit for your storage. E.g. if you want times stored with nanosecond precision, use nanoseconds as your unit of storage.
C++11 introduced std::ratio as the basis for fixed-point conversions between different time units.
If you want to make sure your $scope.somethingHere
value doesn't get overwritten when your view initializes, you'll want to coalesce (somethingHere = somethingHere || options[0].value
) the value in your ng-init like so:
<select ng-model="somethingHere"
ng-init="somethingHere = somethingHere || options[0].value"
ng-options="option.value as option.name for option in options">
</select>
Idea 8.0 has the lovely ctrl+shift+space x 2 that does the following autocomplete:
City city = customer.<ctrl-shift-space twice>
resolves to
City city = customer.getAddress().getCity();
through any number of levels of getters/setters.
If you need a drive letter (some applications don't like UNC style paths that start with a machine-name) you can "map a drive" to a UNC path. Right-click on "My Computer" and select Map Network Drive... or use this command line:
NET USE z: \server\c$\folder1\folder2
NET USE y: \server\d$
Note that you can map drive-to-drive or drill down and map to sub-folder.
It's pretty straightforward using [
to extract:
grep
will give you the position in which it matched your search pattern (unless you use value = TRUE
).
grep("^G45", My.Data$x)
# [1] 2
Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [
(where you would use My.Data[rows, cols]
to get specific rows and columns).
My.Data[grep("^G45", My.Data$x), ]
# x y
# 2 G459 2
The help-page for subset
shows how you can use grep
and grepl
with subset
if you prefer using this function over [
. Here's an example.
subset(My.Data, grepl("^G45", My.Data$x))
# x y
# 2 G459 2
As of R 3.3, there's now also the startsWith
function, which you can again use with subset
(or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring
or grepl
.
subset(My.Data, startsWith(as.character(x), "G45"))
# x y
# 2 G459 2
foreach ($array as $key => $value) {
$class = ( $key !== count( $array ) -1 ) ? " class='not-last'" : " class='last'";
echo "<div{$class}>";
echo "$value['the_title']";
echo "</div>";
}
Try,
string[] files = new DirectoryInfo(dir).GetFiles().Select(o => o.Name).ToArray();

I quite like the way the WordPress works with its enqueue and localize functions, so following that model, I wrote a simple class for putting a scripts into page according to the script dependencies, and for making additional data available for the script.
class mHeader {
private $scripts = array();
/**
* @param string $id Unique script identifier
* @param string $src Script src attribute
* @param array $deps An array of dependencies ( script identifiers ).
* @param array $data An array, data that will be json_encoded and available to the script.
*/
function enqueue_script($id, $src, $deps = array(), $data = array()) {
$this->scripts[$id] = array('src' => $src, 'deps' => $deps, 'data' => $data);
}
private function dependencies($script) {
if ($script['deps']) {
return array_map(array($this, 'dependencies'), array_intersect_key($this->scripts, array_flip($script['deps'])));
}
}
private function _unset($key, &$deps, &$out) {
$out[$key] = $this->scripts[$key];
unset($deps[$key]);
}
private function flattern(&$deps, &$out = array()) {
foreach($deps as $key => $value) {
empty($value) ? $this->_unset($key, $deps, $out) : $this->flattern( $deps[$key], $out);
}
}
function print_scripts() {
if (!$this->scripts)
return;
$deps = array_map(array($this, 'dependencies'), $this->scripts);
while ($deps)
$this->flattern($deps, $js);
foreach($js as $key => $script) {
$script['data'] && printf("<script> var %s = %s; </script>" . PHP_EOL, key($script['data']), json_encode(current( $script['data'])));
echo "<script id=\"$key-js\" src=\"$script[src]\" type=\"text/javascript\"></script>" . PHP_EOL;
}
}
}
The call to the enqueue_script()
function is for adding script, setting the source and dependencies on other scripts, and additional data needed for the script.
$header = new mHeader();
$header->enqueue_script('jquery-ui', '//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js', array('jquery'));
$header->enqueue_script('jquery', '//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js');
$header->enqueue_script('custom-script', '//custom-script.min.js', array('jquery-ui'), array('mydata' => array('value' => 20)));
$header->print_scripts();
And, print_scripts()
method of the above example will send this output:
<script id="jquery-js" src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js" type="text/javascript"></script>
<script id="jquery-ui-js" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js" type="text/javascript"></script>
<script> var mydata = {"value":20}; </script>
<script id="custom-script-js" src="//custom-script.min.js" type="text/javascript"></script>
Regardless the fact that the script 'jquery' is enqueued after the 'jquery-ui', it is printed before because it is defined in 'jquery-ui' that it depends on 'jquery'.
Additional data for the 'custom-script' are inside a new script block and are placed in front of it, it contains mydata
object that holds additional data, now available to 'custom-script'.
I use package hyphenat
and then write compound words like Finnish word Internet-yhteys (Eng. Internet connection) as Internet\hyp yhteys
. Looks goofy but seems to be the most elegant way I've found.
If you saw 404 even everything looks right, try switching https/http.
The original question has the url wrong, usually you can check repo settings and found the correct url for generated site.
However I have everything set up correctly, and the setting page said it's published, then I still saw 404.
Thanks for the comment of @Rohit Suthar (though that comment was to use https), I changed the url to http and it worked, then https worked too.
The documentation is here: http://docs.jquery.com/Ajax/jQuery.ajax
But, to summarize, the ajax call takes a bunch of options. the ones you are looking for are error and success.
You would call it like this:
$.ajax({
url: 'mypage.html',
success: function(){
alert('success');
},
error: function(){
alert('failure');
}
});
I have shown the success and error function taking no arguments, but they can receive arguments.
The error function can take three arguments: XMLHttpRequest, textStatus, and errorThrown.
The success function can take two arguments: data and textStatus. The page you requested will be in the data argument.
Try
checkbox1.onclick= e => {
if(!checkbox1.checked) checkbox1.checked = !confirm("Are you sure?");
textbox1.value = checkbox1.checked;
}
_x000D_
<input type="checkbox" id="checkbox1" /><br />
<input type="text" id="textbox1" value='false'/>
_x000D_
The Jacob Tsui solution works perfect for me:
$('#event_date').datepicker({
showButtonPanel: true,
dateFormat: "mm/dd/yy",
beforeShow: function(){
$(".ui-datepicker").css('font-size', 12)
}
});
I use .map for foreach. For example
success: function(data) {
let dataItems = JSON.parse(data)
dataItems = dataItems.map((item) => {
return $(`<article>
<h2>${item.post_title}</h2>
<p>${item.post_excerpt}</p>
</article>`)
})
},
After several month without real solution for this problem, I suppose that the best solution is to upgrade the application to .NET framework 4.0, which is supported by Windows 8, Windows 10 and Windows 2012 Server by default and it is still available as offline installation for Windows XP.
Ctrl+K,Ctrl+R opens the Object Browser in Visual Studio 2010. Find what you're looking for by searching and browsing and filtering the results. See also Ctrl+Alt+J. ^K ^R
is better because it puts your caret right in the search box, ready to type your new search, even when the Object Browser is already open.
Set the Browse list on the top left to where you want to look to get started. From there you can use the search box (2nd text box from the top, goes all the way across the Object Browser window) or you can just go through everything from the tree on the left. Searches are temporary but the "selected components" set by the Browse list persists. Set a custom set with the little "..." button just to the right of the list.
Objects, packages, namespaces, types, etc. on the left; fields, methods, constants, etc. on the top right, docstrings on the lower right.
The display mode of a pane can be changed by right-clicking in the empty space of the window; tree organized by assembly/container or by namespace and other preferences.
Items can be right-clicked to find, copy and filter.
For keyboard navigation, use Ctrl+K,Ctrl+R from anywhere to start a new search, Enter to execute the search you just typed or pasted and Ctrl+F6 to make the Object Browser close. ALT+<-- to go back and ALT+--> to go forward through the search history. More can be set; search for "ObjectBrowser" in the keyboard shortcut config.
If the key shortcuts above don't work, Object Browser should be in the View menu somewhere with a different shortcut. If all else fails, search for "ObjectBrowser" under Tools->Options->Environment->Keyboard->"Show commands containing".
Suppose STUDENTID contains some characters or numbers that you already know i.e. 'searchstring' then below query will work for you.
You could try this:
select * from STUDENTS where CHARINDEX('searchstring',STUDENTID)>0
I think this one is the fastest and easiest one.
Well, it's not a single statement, but it's about as close as you can get with oracle:
BEGIN
FOR R IN (SELECT owner, table_name FROM all_tables WHERE owner='TheOwner') LOOP
EXECUTE IMMEDIATE 'grant select on '||R.owner||'.'||R.table_name||' to TheUser';
END LOOP;
END;
Simply you can do following stuff using toSql()
method,
$query = DB::table('users')->get();
echo $query->toSql();
If it's not working you can set-up the thing from laravel documentation.
Another way to do it is
DB::getQueryLog()
but if it's returns an empty array then by default it's disabled visit this,
just enable with DB::enableQueryLog()
and it will work :)
for more info visit Github Issue to know more about it.
Hope it helps :)
Try this-
CREATE PROCEDURE simpleproc (IN name varchar(50),IN user_name varchar(50),IN branch varchar(50))
BEGIN
insert into student (name,user_name,branch) values (name ,user_name,branch);
END
You can use
x = [1, 2, 3]
disp(sprintf('Answer: (%d, %d, %d)', x))
This results in
Answer: (1, 2, 3)
For vectors of arbitrary size, you can use
disp(strrep(['Answer: (' sprintf(' %d,', x) ')'], ',)', ')'))
An alternative way would be
disp(strrep(['Answer: (' num2str(x, ' %d,') ')'], ',)', ')'))
You can do this easily manually for each column like this:
df['A_perc'] = df['A']/df['sum']
If you want to do this in one step for all columns, you can use the div
method (http://pandas.pydata.org/pandas-docs/stable/basics.html#matching-broadcasting-behavior):
ds.div(ds['sum'], axis=0)
And if you want this in one step added to the same dataframe:
>>> ds.join(ds.div(ds['sum'], axis=0), rsuffix='_perc')
A B C D sum A_perc B_perc \

Below is the code for ImageFullViewActivity
Class
public class ImageFullViewActivity extends AppCompatActivity {
private ScaleGestureDetector mScaleGestureDetector;
private float mScaleFactor = 1.0f;
private ImageView mImageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.image_fullview);
mImageView = (ImageView) findViewById(R.id.imageView);
mScaleGestureDetector = new ScaleGestureDetector(this, new ScaleListener());
}
@Override
public boolean onTouchEvent(MotionEvent motionEvent) {
mScaleGestureDetector.onTouchEvent(motionEvent);
return true;
}
private class ScaleListener extends ScaleGestureDetector.SimpleOnScaleGestureListener {
@Override
public boolean onScale(ScaleGestureDetector scaleGestureDetector) {
mScaleFactor *= scaleGestureDetector.getScaleFactor();
mScaleFactor = Math.max(0.1f,
Math.min(mScaleFactor, 10.0f));
mImageView.setScaleX(mScaleFactor);
mImageView.setScaleY(mScaleFactor);
return true;
}
}
}
You can easily wrap your button tag with tag.Using Url.Action() HTML Helper this will get to navigate to one page to another.
<a href='@Url.Action("YourAction", "YourController")'>
<input type='button' value='Dummy Button' />
</a>
If you want to navigate with javascript onclick() function then use
<input type='button' value='Dummy Button' onclick='window.location = "@Url.Action("YourAction", "YourController")";' />
I think you need quotes around your {$row['null_field']}
, so '{$row['null_field']}'
If you don't have the quotes, you'll occasionally end up with an insert statement that looks like this: insert into table2 (f1, f2) values ('val1',)
which is a syntax error.
If that is a numeric field, you will have to do some testing above it, and if there is no value in null_field, explicitly set it to null..
You can also "prepend" the environment variable setting by using 'environment' command:
run.doFirst { environment 'SPARK_LOCAL_IP', 'localhost' }
sed 's|(http:\/\/[^\/]+\/).*|\1|'
I still think using Join is simpler. Record the expected completion time (as Now+timeout), then, in a loop, do
if(!thread.Join(End-now))
throw new NotFinishedInTime();
See here: Physical Vs Virtual Memory
Virtual memory is stored on the hard drive and is used when the RAM is filled. Physical memory is limited to the size of the RAM chips installed in the computer. Virtual memory is limited by the size of the hard drive, so virtual memory has the capability for more storage.

In my case I was trying to install Flask. I wanted to run pip install Flask command. But when I open command prompt it I goes to C:\Users[user]>. If you give here it will say pip is not recognized. I did below steps
On your desktop right click Computer and select Properties
Select Advanced Systems Settings
In popup which you see select Advanced tab and then click Environment Variables
In popup double click PATH and from popup copy variable value for variable name PATH and paste the variable value in notepad or so and look for an entry for Python.
In my case it was C:\Users\[user]\AppData\Local\Programs\Python\Python36-32
Now in my command prompt i moved to above location and gave pip install Flask
The operators delete
and delete []
are used respectively to destroy the objects created with new
and new[]
, returning to the allocated memory left available to the compiler's memory manager.
Objects created with new
must necessarily be destroyed with delete
, and that the arrays created with new[]
should be deleted with delete[]
.
The explanation for how it works:
JUnit wraps your test method in a Statement object so statement and Execute()
runs your test. Then instead of calling statement.Execute()
directly to run your test, JUnit passes the Statement to a TestRule with the @Rule
annotation. The TestRule's "apply" function returns a new Statement given the Statement with your test. The new Statement's Execute()
method can call the test Statement's execute method (or not, or call it multiple times), and do whatever it wants before and after
.
Now, JUnit has a new Statement that does more than just run the test, and it can again pass that to any more rules before finally calling Execute.
You can try this:
echo n | copy /-y <SOURCE> <DESTINATION>
-y
simply prompts before overwriting and we can pipe n to all those questions. So this would in essence just copy non-existing files. :)
Across all browsers and simple. this did it for me

You could use PHP's file_get_contents();
<?php
$script = file_get_contents('javascriptFile.js');
echo "<script>".$script."</script>";
?>

Like answered before, you should use:
Object value = field.get(objectInstance);
Another way, which is sometimes prefered, is calling the getter dynamically. example code:
public static Object runGetter(Field field, BaseValidationObject o)
{
// MZ: Find the correct method
for (Method method : o.getMethods())
{
if ((method.getName().startsWith("get")) && (method.getName().length() == (field.getName().length() + 3)))
{
if (method.getName().toLowerCase().endsWith(field.getName().toLowerCase()))
{
// MZ: Method found, run it
try
{
return method.invoke(o);
}
catch (IllegalAccessException e)
{
Logger.fatal("Could not determine method: " + method.getName());
}
catch (InvocationTargetException e)
{
Logger.fatal("Could not determine method: " + method.getName());
}
}
}
}
return null;
}
Also be aware that when your class inherits from another class, you need to recursively determine the Field. for instance, to fetch all Fields of a given class;
for (Class<?> c = someClass; c != null; c = c.getSuperclass())
{
Field[] fields = c.getDeclaredFields();
for (Field classField : fields)
{
result.add(classField);
}
}
SAP is a company and offers a full Enterprise Resource Planning (ERP) system, business platform, and the associated modules (financials, general ledger, &c).
ABAP is the primary programming language used to write SAP software and customizations. It would do it injustice to think of it as COBOL and SQL on steroids, but that gives you an idea. ABAP runs within the SAP system.
SAP and ABAP abstract the DB and run atop various underlying DBMSs.
SAP produces other things as well and even publicly says they dabble in Java and even produce a J2EE container, but tried-and-true SAP is ABAP through-and-through.
You can use Date.before() or Date.after() or Date.equals() for date comparison.
Taken from here:
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class DateDiff {
public static void main( String[] args )
{
compareDates("2017-01-13 00:00:00", "2017-01-14 00:00:00");// output will be Date1 is before Date2
compareDates("2017-01-13 00:00:00", "2017-01-12 00:00:00");//output will be Date1 is after Date2
compareDates("2017-01-13 00:00:00", "2017-01-13 10:20:30");//output will be Date1 is before Date2 because date2 is ahead of date 1 by 10:20:30 hours
compareDates("2017-01-13 00:00:00", "2017-01-13 00:00:00");//output will be Date1 is equal Date2 because both date and time are equal
}
public static void compareDates(String d1,String d2)
{
try{
// If you already have date objects then skip 1
//1
// Create 2 dates starts
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date1 = sdf.parse(d1);
Date date2 = sdf.parse(d2);
System.out.println("Date1"+sdf.format(date1));
System.out.println("Date2"+sdf.format(date2));System.out.println();
// Create 2 dates ends
//1
// Date object is having 3 methods namely after,before and equals for comparing
// after() will return true if and only if date1 is after date 2
if(date1.after(date2)){
System.out.println("Date1 is after Date2");
}
// before() will return true if and only if date1 is before date2
if(date1.before(date2)){
System.out.println("Date1 is before Date2");
}
//equals() returns true if both the dates are equal
if(date1.equals(date2)){
System.out.println("Date1 is equal Date2");
}
System.out.println();
}
catch(ParseException ex){
ex.printStackTrace();
}
}
public static void compareDates(Date date1,Date date2)
{
// if you already have date objects then skip 1
//1
//1
//date object is having 3 methods namely after,before and equals for comparing
//after() will return true if and only if date1 is after date 2
if(date1.after(date2)){

}
//before() will return true if and only if date1 is before date2
if(date1.before(date2)){
System.out.println("Date1 is before Date2");
}
//equals() returns true if both the dates are equal
if(date1.equals(date2)){
System.out.println("Date1 is equal Date2");
}
System.out.println();
}
}
In my case, I solved this by following these two steps
1. Go to android studio preferences -> other settings -> kotlin compiler -> set Target JVM version = 1.8
if it doesn't work then go to the second option.
2. In your module-level build.gradle file add
compileOptions {
sourceCompatibility = 1.8
targetCompatibility = 1.8
}
tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
kotlinOptions {
jvmTarget = "1.8"
}
}
An alternative to using LINQ:
var set = new HashSet<int>(values);
return (1 == set.Count) ? values.First() : otherValue;
I have found using HashSet<T>
is quicker for lists of up to ~ 6,000 integers compared with:
var value1 = items.First();
return values.All(v => v == value1) ? value1: otherValue;
Create a setenv.(sh|bat) file in the tomcat/bin directory with the environment variables that you want modified.
The catalina script checks if the setenv script exists and runs it to set the environment variables. This way you can change the parameters to only one instance of tomcat and is easier to copy it to another instance.
Probably your configuration app has created the setenv script and thats why tomcat is ignoring the environment variables.
This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.
The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)
char *words; // setting this to NULL would have prevented the issue
if (condition) {
words = malloc( 512 );
/* calling free sometime later works here */
free(words)
} else {
/* do not allocate words in this branch */
}
/* free(words); -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/
There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:
*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

An update on @Scott T.'s answer: the interface between Resource Server and Authorization Server for token validation was standardized in IETF RFC 7662 in October 2015, see: https://tools.ietf.org/html/rfc7662. A sample validation call would look like:
POST /introspect HTTP/1.1
Host: server.example.com
Accept: application/json
Content-Type: application/x-www-form-urlencoded
Authorization: Bearer 23410913-abewfq.123483
token=2YotnFZFEjr1zCsicMWpAA
and a sample response:
HTTP/1.1 200 OK
Content-Type: application/json
{
"active": true,
"client_id": "l238j323ds-23ij4",
"username": "jdoe",
"scope": "read write dolphin",

"aud": "https://protected.example.net/resource",
"iss": "https://server.example.com/",
"exp": 1419356238,
"iat": 1419350238,

Of course adoption by vendors and products will have to happen over time.
I have got similar pep8 warning W291 trailing whitespace

Set decoding to true
Your decoding is not set to true. If you don't have access to set the source to true. The code below will fix it for you.
$WorkingArray = json_decode(json_encode($data),true);
The app can't be run natively, but it could be run on an emulator. You can use ManyMo to embed them in a website and make users add your app to their home screen. This link should be useful for making the app more realistic. Users could then only press the share button and add the app to their home screen. All data will be deleted when the "app" is closed in their iOS devices so you should use the Internet/cloud for storage. It can't access camera or multi touch, but it may be useful.
You can't just take the returned string and construct a string from it... it's not a byte[]
data type anymore, it's already a string; you need to parse it. For example :
String response = "[-47, 1, 16, 84, 2, 101, 110, 83, 111, 109, 101, 32, 78, 70, 67, 32, 68, 97, 116, 97]"; // response from the Python script
String[] byteValues = response.substring(1, response.length() - 1).split(",");
byte[] bytes = new byte[byteValues.length];
for (int i=0, len=bytes.length; i<len; i++) {
bytes[i] = Byte.parseByte(byteValues[i].trim());
}
String str = new String(bytes);
** EDIT **
You get an hint of your problem in your question, where you say "Whatever I seem to try I end up getting a byte array which looks as follows... [91, 45, ...
", because 91
is the byte value for [
, so [91, 45, ...
is the byte array of the string "[-45, 1, 16, ...
" string.
The method Arrays.toString()
will return a String
representation of the specified array; meaning that the returned value will not be a array anymore. For example :
byte[] b1 = new byte[] {97, 98, 99};
String s1 = Arrays.toString(b1);
String s2 = new String(b1);
System.out.println(s1); // -> "[97, 98, 99]"
System.out.println(s2); // -> "abc";
As you can see, s1
holds the string representation of the array b1
, while s2
holds the string representation of the bytes contained in b1
.
Now, in your problem, your server returns a string similar to s1
, therefore to get the array representation back, you need the opposite constructor method. If s2.getBytes()
is the opposite of new String(b1)
, you need to find the opposite of Arrays.toString(b1)
, thus the code I pasted in the first snippet of this answer.
So far this has been the most helpful source of information regarding this I could find. Apparently the numbers do NOT reperesent load average in %: http://forum.xda-developers.com/showthread.php?t=1495763
It worked for me.
For rows you can simply use wc -l file
-l
stands for total line
for columns uou can simply use head -1 file | tr ";" "\n" | wc -l
Explanation
head -1 file
Grabbing the first line of your file, which should be the headers,
and sending to it to the next cmd through the pipe
| tr ";" "\n"
tr
stands for translate.
It will translate all ;
characters into a newline character.
In this example ;
is your delimiter.
Then it sends data to next command.
wc -l
Counts the total number of lines.
The right place to download the JDK for Java 7 is Java SE Downloads.
All the other links provided above, as far as I can tell, either provide the JRE or Java 6 downloads (incidentally, if you want to run Eclipse or other IDEs, like IntelliJ IDEA, you will need the JDK, not the JRE).
Regarding IntelliJ IDEA - that will still ask you to install Java 6 as it apparently needs an older class loader or something: just follow the instructions when the dialog pop-up appears and it will install the JDK 6 in the right place.
Afterwards, you will need to do the sudo ln -snf
mentioned in the answer above:
sudo ln -nsf /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents \
/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK
(copied here as it was mentioned that "above" may eventually not make sense as answers are re-sorted).
I also set my JAVA_HOME
to point to where jdk_1.7.0_xx.jdk
was installed:
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home"
Then add that to your PATH
:
export PATH=$JAVA_HOME/bin:$PATH
The alternative is to fuzz around with Apple's insane maze of hyperlinks, but honestly life is too short to bother.
You can also add prompt option like this.
<%= f.select(:object_field, ['Item 1', 'Item 2'], {include_blank: "Select something"}, { :class => 'my_style_class' }) %>

Possibly one of the better examples of 'There's More Than One Way To Do It", with or without the help of CPAN.
If you have control over what you get passed as a 'date/time', I'd suggest going the DateTime route, either by using a specific Date::Time::Format subclass, or using DateTime::Format::Strptime if there isn't one supporting your wacky date format (see the datetime FAQ for more details). In general, Date::Time is the way to go if you want to do anything serious with the result: few classes on CPAN are quite as anal-retentive and obsessively accurate.
If you're expecting weird freeform stuff, throw it at Date::Parse's str2time() method, which'll get you a seconds-since-epoch value you can then have your wicked way with, without the overhead of Date::Manip.
You can do union
or simple list comprehension
[A.add(_) for _ in B]
A would have all the elements of B
We should rather use Javascript.

There is no "DOS command prompt". DOS fully died with Windows ME (7/11/2006). It's simply called the Command Prompt on Windows NT (which is NT, 2K, XP, Vista, 7).
There is no way to alter the screen buffer through built-in cmd.exe commands. It can be altered through Console API Functions, so you might be able to create a utility to modify it. I've never tried this myself.
Another suggestion would be to redirect output to both a file and to the screen so that you have a "hard copy" of it. Windows does not have a TEE command like Unix, but someone has remedied that.
int h = Screen.PrimaryScreen.WorkingArea.Height;
int w = Screen.PrimaryScreen.WorkingArea.Width;
this.ClientSize = new Size(w , h);
I know this thread is old but, another solution was to run
$ mvn clean install -Dmaven.test.skip=true
And on IntelliJ do CMD + Shift + A (mac os) -> type "Reimport all Maven projects".
If that doesn't work, try forcing maven dependencies to be re-downloaded
$ mvn clean -U install -Dmaven.test.skip=true
Use HH
for 24 hour hours format:
DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")
Or the tt
format specifier for the AM/PM
part:
DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss tt")
Take a look at the custom Date and Time format strings documentation.
Having the same chore on windows 10, and windows server 2012. I found the following solution:
echo quit |sqlplus schemaName/schemaPassword@sid @plsqlScript.sql > outputFile.log
echo quit |
send the quit command to exit sqlplus
after the script completes
sqlplus schemaName/schemaPassword@sid @plsqlScript.sql
execute plssql script plsqlScript.sql
in schema schemaName
with password schemaPassword
connecting to SID sid
> outputFile.log
redirect sqlplus output to log file outputFile.log
Just Go to Model file of the corresponding Controller and check the primary key filed name
such as
protected $primaryKey = 'info_id';
here info id is field name available in database table
More info can be found at "Primary Keys" section of the docs.
Stream<Integer> stream = Stream.of(1, 2, 3, 4, 5, 6);
Integer[] integers = stream.toArray(it->new Integer[it]);
In programming languages, a type is some data and the associated operations. An ADT is a user defined data aggregate and the operations over these data and is characterized by encapsulation, the data and operations are represented, or at list declared, in a single syntactic unit, and information hiding, only the relevant operations are visible for the user of the ADT, the ADT interface, in the same way that a normal data type in the programming language. It's an abstraction because the internal representation of the data and implementation of the operations are of no concern to the ADT user.

You could declare one or more of your targets to be phony.
A phony target is one that is not really the name of a file; rather it is just a name for a recipe to be executed when you make an explicit request. There are two reasons to use a phony target: to avoid a conflict with a file of the same name, and to improve performance.
...
A phony target should not be a prerequisite of a real target file; if it is, its recipe will be run every time make goes to update that file. As long as a phony target is never a prerequisite of a real target, the phony target recipe will be executed only when the phony target is a specified goal
I don't think having a list of chars to remove is safe. I would rather use the following:
For filenames: Use an internal ID or a hash of the filecontent. Save the document name in a database. This way you can keep the original filename and still find the file.
For url parameters: Use urlencode()
to encode any special characters.
In case anyone else needs to add padding to something with background-image and background-size: contain or cover, I used the following which is a nice way of doing it. You can replace the border-width with 10% or 2vw or whatever you like.
.bg-image {
background: url("/image/logo.png") no-repeat center #ffffff / contain;
border: inset 10px transparent;
box-sizing: border-box;
}
This means you don't have to define a width.
If you want to see output logs from all the services in your terminal.
docker-compose logs -t -f --tail <no of lines>
Eg.: Say you would like to log output of last 5 lines from all service
docker-compose logs -t -f --tail 5
If you wish to log output from specific services then it can be done as below:
docker-compose logs -t -f --tail <no of lines> <name-of-service1> <name-of-service2> ... <name-of-service N>
Usage:
Eg. say you have API and portal services then you can do something like below :
docker-compose logs -t -f --tail 5 portal api
Where 5 represents last 5 lines from both logs.
Ref: https://docs.docker.com/v17.09/engine/admin/logging/view_container_logs/
Also you can try this line to get string value from app.config
file.
var strName= ConfigurationManager.AppSettings["stringName"];
A simple performance test for ConcurrentHashMap vs Synchronized HashMap
. The test flow is calling put
in one thread and calling get
in three threads on Map
concurrently. As @trshiv said, ConcurrentHashMap has higher throughput and speed for whose reading operation without lock. The result is when operation times is over 10^7
, ConcurrentHashMap is 2x
faster than Synchronized HashMap.
This task can be accomplished without blueprints and tricky imports using Centralized URL Map

Use an outer wrapper div set to 100% and then your inner wrapper div 100% should be now relative to that.
I thought for sure this used to work for me, but apparently not:
<html>
<body>
<div id="outerwrapper" style="border : 1px solid red ; height : 100%">
<div id="header" style="border : 1px solid blue ; height : 60px"></div>
<div id="wrapper" style="border : 1px solid green ; height : 100% ; overflow : scroll ;">
<div id="left" style="height : 100% ; width : 50% ; overflow : scroll; float : left ; clear : left ;">Some text
on the left</div>
<div id="right" style="height : 100% ; width 50% ; overflow : scroll; float : left ;">Some Text on the
right</div>
</div>
</div>
</body>

You want to use timeout. timeout 10 will sleep 10 seconds

First a very important point, from which everything will follow (I hope).
In ordinary Python, list
is not special in any way (except having cute syntax for constructing, which is mostly a historical accident). Once a list [3,2,6]
is made, it is for all intents and purposes just an ordinary Python object, like a number 3
, set {3,7}
, or a function lambda x: x+5
.
(Yes, it supports changing its elements, and it supports iteration, and many other things, but that's just what a type is: it supports some operations, while not supporting some others. int supports raising to a power, but that doesn't make it very special - it's just what an int is. lambda supports calling, but that doesn't make it very special - that's what lambda is for, after all:).
and
and
is not an operator (you can call it "operator", but you can call "for" an operator too:). Operators in Python are (implemented through) methods called on objects of some type, usually written as part of that type. There is no way for a method to hold an evaluation of some of its operands, but and
can (and must) do that.
The consequence of that is that and
cannot be overloaded, just like for
cannot be overloaded. It is completely general, and communicates through a specified protocol. What you can do is customize your part of the protocol, but that doesn't mean you can alter the behavior of and
completely. The protocol is:
Imagine Python interpreting "a and b" (this doesn't happen literally this way, but it helps understanding). When it comes to "and", it looks at the object it has just evaluated (a), and asks it: are you true? (NOT: are you True
?) If you are an author of a's class, you can customize this answer. If a
answers "no", and
(skips b completely, it is not evaluated at all, and) says: a
is my result (NOT: False is my result).
If a
doesn't answer, and
asks it: what is your length? (Again, you can customize this as an author of a
's class). If a
answers 0, and
does the same as above - considers it false (NOT False), skips b, and gives a
as result.
If a
answers something other than 0 to the second question ("what is your length"), or it doesn't answer at all, or it answers "yes" to the first one ("are you true"), and
evaluates b, and says: b
is my result. Note that it does NOT ask b
any questions.
The other way to say all of this is that a and b
is almost the same as b if a else a
, except a is evaluated only once.
Now sit for a few minutes with a pen and paper, and convince yourself that when {a,b} is a subset of {True,False}, it works exactly as you would expect of Boolean operators. But I hope I have convinced you it is much more general, and as you'll see, much more useful this way.
Now I hope you understand your example 1. and
doesn't care if mylist1 is a number, list, lambda or an object of a class Argmhbl. It just cares about mylist1's answer to the questions of the protocol. And of course, mylist1 answers 5 to the question about length, so and returns mylist2. And that's it. It has nothing to do with elements of mylist1 and mylist2 - they don't enter the picture anywhere.
&
on list
On the other hand, &
is an operator like any other, like +
for example. It can be defined for a type by defining a special method on that class. int
defines it as bitwise "and", and bool defines it as logical "and", but that's just one option: for example, sets and some other objects like dict keys views define it as a set intersection. list
just doesn't define it, probably because Guido didn't think of any obvious way of defining it.
On the other leg:-D, numpy arrays are special, or at least they are trying to be. Of course, numpy.array is just a class, it cannot override and
in any way, so it does the next best thing: when asked "are you true", numpy.array raises a ValueError, effectively saying "please rephrase the question, my view of truth doesn't fit into your model". (Note that the ValueError message doesn't speak about and
- because numpy.array doesn't know who is asking it the question; it just speaks about truth.)
For &
, it's completely different story. numpy.array can define it as it wishes, and it defines &
consistently with other operators: pointwise. So you finally get what you want.
HTH,
string[] lines = input.Split(new[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);
For me Pawan's css class combined with display: inline-block (so the selects don't stack) works best. And I wrap it in a media-query, so it stays Mobile Friendly:
@media (min-width: $screen-xs) {
.selectwidthauto {
width:auto !important;
display: inline-block;
}
}
This regex will split word by space like space, tab, line break:
String[] str = s.split("\\s+");
Ryan Bates uses a nice little bit of code in his Railscast on beta invitations. This produces a 40 character alphanumeric string.
Digest::SHA1.hexdigest([Time.now, rand].join)
You probably had a typo when you first ran it.
evaluating 0.5 % 0.3
returns '0.2' (A double) as expected.
Mindprod has a good overview of how modulus works in Java.
In Java, when you write:
Object objectA = new Object();
Object objectB = objectA;
objectA
and objectB
are the same and point to the same reference. Changing one will change the other. So if you change the state of objectA
(not its reference) objectB
will reflect that change too.
However, if you write:
objectA = new Object()
Then objectB
is still pointing to the first object you created (original objectA
) while objectA
is now pointing to a new Object.
