Ad hoc queries are those that are not already defined that are not needed on a regular basis, so they're not included in the typical set of reports or queries
truncate -s 10M output.file
will create a 10 M file instantaneously (M stands for 10241024 bytes, MB stands for 10001000 - same with K, KB, G, GB...)
EDIT: as many have pointed out, this will not physically allocate the file on your device. With this you could actually create an arbitrary large file, regardless of the available space on the device, as it creates a "sparse" file.
For e.g. notice no HDD space is consumed with this command:
### BEFORE
$ df -h | grep lvm
/dev/mapper/lvm--raid0-lvm0
7.2T 6.6T 232G 97% /export/lvm-raid0
$ truncate -s 500M 500MB.file
### AFTER
$ df -h | grep lvm
/dev/mapper/lvm--raid0-lvm0
7.2T 6.6T 232G 97% /export/lvm-raid0
So, when doing this, you will be deferring physical allocation until the file is accessed. If you're mapping this file to memory, you may not have the expected performance.
But this is still a useful command to know. For e.g. when benchmarking transfers using files, the specified size of the file will still get moved.
$ rsync -aHAxvP --numeric-ids --delete --info=progress2 \
[email protected]:/export/lvm-raid0/500MB.file \
/export/raid1/
receiving incremental file list
500MB.file

sent 30 bytes received 524,352,082 bytes 38,840,897.19 bytes/sec
total size is 524,288,000 speedup is 1.00
This works perfectly as we want:
Unzip files:
find . -name "*.zip" | xargs -P 5 -I FILENAME sh -c 'unzip -o -d "$(dirname "FILENAME")" "FILENAME"'
Above command does not create duplicate directories.
Remove all zip files:
find . -depth -name '*.zip' -exec rm {} \;
Here's another way:
>>> L = range (11)
>>> map(lambda x: x if x%2 else None, L)
[None, 1, None, 3, None, 5, None, 7, None, 9, None]
It's important to note that using viewDidLoad for positioning is a bit risky and should be avoided since the bounds are not set. this may cause unexpected results (I had a variety of issues...)
This post describes quite well the different methods and what happens in each of them.
currently for one-time init and positioning I'm thinking of using viewDidAppear with a flag, if anyone has any other recommendation please let me know.
If you need async: false
in your ajax, you should use success
instead of .done
. Else you better to use .done
.
This is from jQuery official site:
As of jQuery 1.8, the use of async: false with jqXHR ($.Deferred) is deprecated; you must use the success/error/complete callback options instead of the corresponding methods of the jqXHR object such as jqXHR.done().
Problem statement – Getting java.awt.HeadlessException while trying to initialize java.awt.Component from the application as the tomcat environment does not have any head(terminal).
Issue – The linux virtual environment was setup without a virtual display terminal. Tried to install virtual display – Xvfb, but Xvfb has been taken off by the redhat community.
Solution – Installed ‘xorg-x11-drv-vmware.x86_64’ using yum install xorg-x11-drv-vmware.x86_64 and executed startx. Finally set the display to :0.0 using export DISPLAY=:0.0 and then executed xhost +
Another option would be to just use the excellent corrr
package https://github.com/drsimonj/corrr and do
require(corrr)
require(dplyr)
myData %>%
select(x,y,z) %>% # or do negative or range selections here
correlate() %>%
rearrange() %>% # rearrange by correlations
shave() # Shave off the upper triangle for a cleaner result
Steps 3 and 4 are entirely optional and are just included to demonstrate the usefulness of the package.
I was facing the same problem. Removing the bin\
from the HADOOP_HOME path solved it for me. The path for HADOOP_HOME variable should look something like.
C:\dev\hadoop2.6\
System restart may be needed. In my case, restarting the IDE was sufficient.
defaultValue instead of value worked for me .
In your PRIMARY KEY definition you've used (id(11))
, which defines a prefix key - i.e. the first 11 characters only should be used to create an index. Prefix keys are only valid for CHAR
, VARCHAR
, BINARY
and VARBINARY
types and your id
field is an int
, hence the error.
Use PRIMARY KEY (id)
instead and you should be fine.
MySQL reference here and read from paragraph 4.
In case you using lookup to set default read from environment you have also set the second parameter of default to true:
- set_facts:
ansible_ssh_user: "{{ lookup('env', 'SSH_USER') | default('foo', true) }}"
You can also concatenate multiple default definitions:
- set_facts:
ansible_ssh_user: "{{ some_var.split('-')[1] | default(lookup('env','USER'), true) | default('foo') }}"
There don't seem to be a variable which holds exactly what you want.
However, quoting the docs:
Also available,
inventory_dir
is the pathname of the directory holding Ansible’s inventory host file,inventory_file
is the pathname and the filename pointing to the Ansible’s inventory host file.playbook_dir contains the playbook base directory.
And finally,
role_path
will return the current role’s pathname (since 1.8). This will only work inside a role.
Dependent on your setup, those or the $ pwd
-based solution might be enough.
Well, here is the final answer. I have used great Jimmy idea (which unfortunately is not complete itself) and complete recursion function to work properly.
Based on interface:
string RemoveAllNamespaces(string xmlDocument);
I represent here final clean and universal C# solution for removing XML namespaces:
//Implemented based on interface, not part of algorithm
public static string RemoveAllNamespaces(string xmlDocument)
{
XElement xmlDocumentWithoutNs = RemoveAllNamespaces(XElement.Parse(xmlDocument));
return xmlDocumentWithoutNs.ToString();
}
//Core recursion function
private static XElement RemoveAllNamespaces(XElement xmlDocument)
{
if (!xmlDocument.HasElements)
{
XElement xElement = new XElement(xmlDocument.Name.LocalName);
xElement.Value = xmlDocument.Value;
foreach (XAttribute attribute in xmlDocument.Attributes())
xElement.Add(attribute);
return xElement;
}
return new XElement(xmlDocument.Name.LocalName, xmlDocument.Elements().Select(el => RemoveAllNamespaces(el)));
}
It's working 100%, but I have not tested it much so it may not cover some special cases... But it is good base to start.
Since the behavior is kind of strange, I have done some testing on the behavior, and here's my result:
If you are:
form
, andonclick="xxx()"
on an elementid="xxx"
or name="xxx"
to that element
Here's are some test and their result:
function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }
_x000D_
<form onsubmit="return false;">
<button onclick="totalbandwidth()">SUCCESS</button>
</form>
_x000D_
function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }
_x000D_
<form onsubmit="return false;">
<button id="totalbandwidth" onclick="totalbandwidth()">FAILED</button>
</form>
_x000D_
function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

_x000D_
<button id="totalbandwidth" onclick="totalbandwidth()">SUCCESS</button>
_x000D_
function totalbandwidth(){ alert("The answer is no, the span will not affect button"); }
_x000D_
<form onsubmit="return false;">
<span name="totalbandwidth" >Will this span affect button? </span>
<button onclick="totalbandwidth()">SUCCESS</button>
</form>

I'm a proponent of not assuming the best solution and testing it. Below are some modifications I did to create simple classes of examples by both @igor-chubin and @user448810. First off let me say it's all great information, thank you guys. But I have to acknowledge @user448810 for his clever solution, which turns out to be the fastest by far (of those I tested). So kudos to you, sir! In all examples I use a values of 1 million (1,000,000) as n.
Please feel free to try the code out.
Good luck!
Method 1 as described by Igor Chubin:
def primes_method1(n):
out = list()
for num in range(1, n+1):
prime = True
for i in range(2, num):
if (num % i == 0):
prime = False
if prime:
out.append(num)
return out
Benchmark: Over 272+ seconds
Method 2 as described by Igor Chubin:
def primes_method2(n):
out = list()
for num in range(1, n+1):
if all(num % i != 0 for i in range(2, num)):
out.append(num)
return out
Benchmark: 73.3420000076 seconds
Method 3 as described by Igor Chubin:
def primes_method3(n):
out = list()
for num in range(1, n+1):
if all(num % i != 0 for i in range(2, int(num**.5 ) + 1)):
out.append(num)
return out
Benchmark: 11.3580000401 seconds
Method 4 as described by Igor Chubin:
def primes_method4(n):
out = list()
out.append(2)
for num in range(3, n+1, 2):
if all(num % i != 0 for i in range(2, int(num**.5 ) + 1)):
out.append(num)
return out
Benchmark: 8.7009999752 seconds
Method 5 as described by user448810 (which I thought was quite clever):
def primes_method5(n):
out = list()
sieve = [True] * (n+1)
for p in range(2, n+1):
if (sieve[p]):
out.append(p)
for i in range(p, n+1, p):
sieve[i] = False
return out
Benchmark: 1.12000012398 seconds
Notes: Solution 5 listed above (as proposed by user448810) turned out to be the fastest and honestly quiet creative and clever. I love it. Thanks guys!!
EDIT: Oh, and by the way, I didn't feel there was any need to import the math library for the square root of a value as the equivalent is just (n**.5). Otherwise I didn't edit much other then make the values get stored in and output array to be returned by the class. Also, it would probably be a bit more efficient to store the results to a file than verbose and could save a lot on memory if it was just one at a time but would cost a little bit more time due to disk writes. I think there is always room for improvement though. So hopefully the code makes sense guys.
2021 EDIT: I know it's been a really long time but I was going back through my Stackoverflow after linking it to my Codewars account and saw my recently accumulated points, which which was linked to this post. Something I read in the original poster caught my eye for @user448810, so I decided to do a slight modification mentioned in the original post by filtering out odd values before appending the output array. The results was much better performance for both the optimization as well as latest version of Python 3.8 with a result of 0.723 seconds (prior code) vs 0.504 seconds using 1,000,000 for n.
def primes_method5(n):
out = list()
sieve = [True] * (n+1)
for p in range(2, n+1):
if (sieve[p] and sieve[p]%2==1):
out.append(p)
for i in range(p, n+1, p):
sieve[i] = False
return out
Nearly five years later, I might know a bit more but I still just love Python, and it's kind of crazy to think it's been that long. The post honestly feels like it was made a short time ago and at the time I had only been using python about a year I think. And it still seems relevant. Crazy. Good times.
Checkboxes, by design, are meant to be toggled on or off. They are not dependent on other checkboxes, so you can turn as many on and off as you wish.
Radio buttons, however, are designed to only allow one element of a group to be selected at any time.

This is mentioned at the bottom of the blog post already linked above but this works like a treat for me:
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
marshaller.marshal(new JAXBElement<MyClass>(new QName("uri","local"), MyClass.class, myClassInstance), System.out);
you can take care of the first 3 items with slicing and head:
df[df.A>=4].head(1)
df[(df.A>=4)&(df.B>=3)].head(1)
df[(df.A>=4)&((df.B>=3) * (df.C>=2))].head(1)
The condition in case nothing comes back you can handle with a try or an if...
try:
output = df[df.A>=6].head(1)
assert len(output) == 1
except:
output = df.sort_values('A',ascending=False).head(1)
In my case, I was copying and pasting code from my other classes, so I did not notice that the getter code was bad written:
@OneToMany(fetch = FetchType.LAZY, mappedBy = "credito")
public Set getConceptoses() {
return this.letrases;
}
public void setConceptoses(Set conceptoses) {
this.conceptoses = conceptoses;
}
All references conceptoses but if you look at the get says letrases

Some of the answers here imply that given a "package" directory (with or without an explicit __init__.py
file), containing a __main__.py
file, there is no difference between running that directory with the -m
switch or without.
The big difference is that without the -m
switch, the "package" directory is first added to the path (i.e. sys.path), and then the files are run normally, without package semantics.
Whereas with the -m
switch, package semantics (including relative imports) are honoured, and the package directory itself is never added to the system path.
This is a very important distinction, both in terms of whether relative imports will work or not, but more importantly in terms of dictating what will be imported in the case of unintended shadowing of system modules.
Example:
Consider a directory called PkgTest
with the following structure
:~/PkgTest$ tree
.
+-- pkgname
¦ +-- __main__.py
¦ +-- secondtest.py
¦ +-- testmodule.py
+-- testmodule.py
where the __main__.py
file has the following contents:
:~/PkgTest$ cat pkgname/__main__.py
import os
print( "Hello from pkgname.__main__.py. I am the file", os.path.abspath( __file__ ) )
print( "I am being accessed from", os.path.abspath( os.curdir ) )
from testmodule import main as firstmain; firstmain()
from .secondtest import main as secondmain; secondmain()
(with the other files defined similarly with similar printouts).
If you run this without the -m
switch, this is what you'll get. Note that the relative import fails, but more importantly note that the wrong testmodule has been chosen (i.e. relative to the working directory):
:~/PkgTest$ python3 pkgname
Hello from pkgname.__main__.py. I am the file ~/PkgTest/pkgname/__main__.py
I am being accessed from ~/PkgTest
Hello from testmodule.py. I am the file ~/PkgTest/pkgname/testmodule.py
I am being accessed from ~/PkgTest
Traceback (most recent call last):
File "/usr/lib/python3.6/runpy.py", line 193, in _run_module_as_main
"__main__", mod_spec)
File "/usr/lib/python3.6/runpy.py", line 85, in _run_code
exec(code, run_globals)
File "pkgname/__main__.py", line 10, in <module>
from .secondtest import main as secondmain
ImportError: attempted relative import with no known parent package
Whereas with the -m switch, you get what you (hopefully) expected:
:~/PkgTest$ python3 -m pkgname
Hello from pkgname.__main__.py. I am the file ~/PkgTest/pkgname/__main__.py
I am being accessed from ~/PkgTest
Hello from testmodule.py. I am the file ~/PkgTest/testmodule.py
I am being accessed from ~/PkgTest
Hello from secondtest.py. I am the file ~/PkgTest/pkgname/secondtest.py
I am being accessed from ~/PkgTest
Note: In my honest opinion, running without -m
should be avoided. In fact I would go further and say that I would create any executable packages
in such a way that they would fail unless run via the -m
switch.
In other words, I would only import from 'in-package' modules explicitly via 'relative imports', assuming that all other imports represent system modules. If someone attempts to run your package without the -m
switch, the relative import statements will throw an error, instead of silently running the wrong module.
some_list2 += ["something"]
is actually
some_list2.extend(["something"])
for one value, there is no difference. Documentation states, that:
s.append(x)
same ass[len(s):len(s)] = [x]
s.extend(x)
same ass[len(s):len(s)] = x
Thus obviously s.append(x)
is same as s.extend([x])
Also, bear in mind that if you need to export multiple functions at once, like actions you can use
export * from './XThingActions';
pgAdmin 4 is a powerful and popular web-based database management tool for PostgreSQL - http://www.pgadmin.org/
The history limit is a pane attribute that is fixed at the time of pane creation and cannot be changed for existing panes. The value is taken from the history-limit
session option (the default value is 2000).
To create a pane with a different value you will need to set the appropriate history-limit
option before creating the pane.
To establish a different default, you can put a line like the following in your .tmux.conf
file:
set-option -g history-limit 3000
Note: Be careful setting a very large default value, it can easily consume lots of RAM if you create many panes.
For a new pane (or the initial pane in a new window) in an existing session, you can set that session’s history-limit
. You might use a command like this (from a shell):
tmux set-option history-limit 5000 \; new-window
For (the initial pane of the initial window in) a new session you will need to set the “global” history-limit
before creating the session:
tmux set-option -g history-limit 5000 \; new-session
Note: If you do not re-set the history-limit
value, then the new value will be also used for other panes/windows/sessions created in the future; there is currently no direct way to create a single new pane/window/session with its own specific limit without (at least temporarily) changing history-limit
(though show-option
(especially in 1.7 and later) can help with retrieving the current value so that you restore it later).

I've used the solution described here http://jtruher.spaces.live.com/blog/cns!7143DA6E51A2628D!130.entry successfully in PowerShell v1.0. It definitely will be easier in PowerShell v2.0.
Every performance problem with PyCharm is unique, a solution that helps to one person will not work for another. The only proper way to fix your specific performance problem is by capturing the CPU profiler snapshot as described in this document and sending it to PyCharm support team, either by submitting a ticket or directly into the issue tracker.
After the CPU snapshot is analyzed, PyCharm team will work on a fix and release a new version which will (hopefully) not be affected by this specific performance problem. The team may also suggest you some configuration change or workaround to remedy the problem based on the analysis of the provided data.
All the other "solutions" (like enabling Power Save mode and changing the highlighting level) will just hide the real problems that should be fixed.

Use this method and pass your array in parameter
Collections.shuffle(arrayList);
This method return void so it will not give you a new list but as we know that array is passed as a reference type in Java so it will shuffle your array and save shuffled values in it. That's why you don't need any return type.
You can now use arraylist which is shuffled.

EDIT 2020-09-21: Since 3.4.0, Mockito supports mocking static methods, API is still incubating and is likely to change, in particular around stubbing and verification. It requires the mockito-inline
artifact. And you don't need to prepare the test or use any specific runner. All you need to do is :
@Test
public void name() {
try (MockedStatic<LoggerFactory> integerMock = mockStatic(LoggerFactory.class)) {
final Logger logger = mock(Logger.class);
integerMock.when(() -> LoggerFactory.getLogger(any(Class.class))).thenReturn(logger);
new Controller().log();
verify(logger).warn(any());
}
}
The two inportant aspect in this code, is that you need to scope when the static mock applies, i.e. within this try block. And you need to call the stubbing and verification api from the MockedStatic
object.
@Mick, try to prepare the owner of the static field too, eg :
@PrepareForTest({GoodbyeController.class, LoggerFactory.class})
EDIT1 : I just crafted a small example. First the controller :
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class Controller {
Logger logger = LoggerFactory.getLogger(Controller.class);
public void log() { logger.warn("yup"); }
}
Then the test :
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import static org.mockito.Matchers.any;
import static org.mockito.Matchers.anyString;
import static org.mockito.Mockito.verify;
import static org.powermock.api.mockito.PowerMockito.mock;
import static org.powermock.api.mockito.PowerMockito.mockStatic;
import static org.powermock.api.mockito.PowerMockito.when;
@RunWith(PowerMockRunner.class)
@PrepareForTest({Controller.class, LoggerFactory.class})
public class ControllerTest {
@Test
public void name() throws Exception {
mockStatic(LoggerFactory.class);
Logger logger = mock(Logger.class);
when(LoggerFactory.getLogger(any(Class.class))).thenReturn(logger);
new Controller().log();
verify(logger).warn(anyString());
}
}
Note the imports ! Noteworthy libs in the classpath : Mockito, PowerMock, JUnit, logback-core, logback-clasic, slf4j
EDIT2 : As it seems to be a popular question, I'd like to point out that if these log messages are that important and require to be tested, i.e. they are feature / business part of the system then introducing a real dependency that make clear theses logs are features would be a so much better in the whole system design, instead of relying on static code of a standard and technical classes of a logger.
For this matter I would recommend to craft something like= a Reporter
class with methods such as reportIncorrectUseOfYAndZForActionX
or reportProgressStartedForActionX
. This would have the benefit of making the feature visible for anyone reading the code. But it will also help to achieve tests, change the implementations details of this particular feature.
Hence you wouldn't need static mocking tools like PowerMock. In my opinion static code can be fine, but as soon as the test demands to verify or to mock static behavior it is necessary to refactor and introduce clear dependencies.
I had the same issue as OP but none of the current answers solved my issue so to add a slightly different answer that did work for me:
Running Python 3.6.5 on a Windows Machine, I used the format
r"\DriveName\then\file\path\txt.md"
so the combination of double backslashes from reading @Johnsyweb UNC link and adding the r in front as recommended solved my similar to OP's issue.

Service Oriented Architecture (SOA) is a software architectural style that builds applications as a collection of pluggable parts, each of which can be reused by other applications.
I've encountered some problems such as RemoteServiceException because of invalid channel id with most recent versions of Android. This is how i solved it:
Activity:
override fun onCreate(savedInstanceState: Bundle?) {
val intent = Intent(this, BackgroundService::class.java)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
startForegroundService(intent)
} else {
startService(intent)
}
}
BackgroundService:
override fun onCreate() {
super.onCreate()
startForeground()
}
private fun startForeground() {
val service = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val channelId =
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
createNotificationChannel()
} else {
// If earlier version channel ID is not used
// https://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#NotificationCompat.Builder(android.content.Context)
""
}
val notificationBuilder = NotificationCompat.Builder(this, channelId )
val notification = notificationBuilder.setOngoing(true)
.setSmallIcon(R.mipmap.ic_launcher)
.setPriority(PRIORITY_MIN)
.setCategory(Notification.CATEGORY_SERVICE)
.build()
startForeground(101, notification)
}
@RequiresApi(Build.VERSION_CODES.O)
private fun createNotificationChannel(): String{
val channelId = "my_service"
val channelName = "My Background Service"
val chan = NotificationChannel(channelId,
channelName, NotificationManager.IMPORTANCE_HIGH)
chan.lightColor = Color.BLUE
chan.importance = NotificationManager.IMPORTANCE_NONE
chan.lockscreenVisibility = Notification.VISIBILITY_PRIVATE
val service = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
service.createNotificationChannel(chan)
return channelId
}
JAVA EQUIVALENT
public class YourService extends Service {
// Constants
private static final int ID_SERVICE = 101;
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);

I find adding this to django models quite helpful:
def __iter__(self):
for field_name in self._meta.get_all_field_names():
value = getattr(self, field_name, None)
yield (field_name, value)
This lets you do:
for field, val in object:
print field, val
You should add the g
modifier so that sed performs a global substitution of the contents of the pattern buffer:
echo dog dog dos | sed -e 's:dog:log:g'
For a fantastic documentation on sed, check http://www.grymoire.com/Unix/Sed.html. This global flag is explained here: http://www.grymoire.com/Unix/Sed.html#uh-6
The official documentation for GNU sed
is available at http://www.gnu.org/software/sed/manual/
w/o flip:
<?php
foreach ($items as $key => $value) {
if ($id === $value) {
unset($items[$key]);
}
}
function functionname() {
var divToPrint = document.getElementById('divid');
newWin= window.open();
newWin.document.write(divToPrint.innerHTML);
newWin.location.reload();
newWin.focus();
newWin.print();
newWin.close();
}
You need make sure to start the session at the top of every PHP file where you want to use the $_SESSION
superglobal. Like this:
<?php
session_start();
echo $_SESSION['youritem'];
?>
You forgot the Session HELPER.
Check this link : book.cakephp.org/2.0/en/core-libraries/helpers/session.html
This tool may be is what you want: tbdba-restore-mysqldump.pl
https://github.com/orczhou/dba-tool/blob/master/tbdba-restore-mysqldump.pl
e.g. Restore a table from database dump file:
tbdba-restore-mysqldump.pl -t yourtable -s yourdb -f backup.sql
You need to create a certificate and sign gdb:
Finally you can sign gdb:
sudo codesign -s gdb-cert /usr/local/bin/ggdb
sudo ggdb ./myprog
foreach ($_POST["select2"] as $selectedOption)
{
echo $selectedOption."\n";
}
If you want to swap string. it's already the efficient way to do that.
However, if you want to swap integer, you can use XOR to swap two integers more efficiently like this:
int a = 1; int b = 2; a ^= b; b ^= a; a ^= b;
This line solved my problem in CMD:
npm install --save-dev nodemon
SonarQube documentation recommends adding static
keyword to the class declaration.
That is, change public class FilePathHelper
to public static class FilePathHelper
.
Alternatively you can add a private or protected constructor.
public class FilePathHelper
{
// private or protected constructor
// because all public fields and methods are static
private FilePathHelper() {
}
}
I had this issue, and I set the Locale
to US
, then it work.
static DateFormat visitTimeFormat = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy",Locale.US);
for String
"Sun Jul 08 00:06:30 UTC 2012"
/*working only in ipad portrait device*/
@media only screen and (width: 768px) and (height: 1024px) and (orientation:portrait) {
body{
background: red !important;
}
}
/*working only in ipad landscape device*/
@media all and (width: 1024px) and (height: 768px) and (orientation:landscape){
body{
background: green !important;
}
}
In the media query of specific devices, please use '!important' keyword to override the default CSS. Otherwise that does not change your webpage view on that particular devices.
Similar to answer by @Jeff_Alieffson, but not relying on default Locale
:
Use DecimalFormatSymbols
for explicit locale:
DecimalFormatSymbols decimalFormatSymbols = DecimalFormatSymbols.getInstance(new Locale("ru", "RU"));
Or explicit separator symbols:
DecimalFormatSymbols decimalFormatSymbols = new DecimalFormatSymbols();
decimalFormatSymbols.setDecimalSeparator('.');
decimalFormatSymbols.setGroupingSeparator(' ');
Then:
new DecimalFormat("#,##0.00", decimalFormatSymbols).format(new BigDecimal("12345"));
Result:
12 345.00
Solution from typescript interfaces reference:
interface ClockConstructor {
new (hour: number, minute: number): ClockInterface;
}
interface ClockInterface {
tick();
}
function createClock(ctor: ClockConstructor, hour: number, minute: number): ClockInterface {
return new ctor(hour, minute);
}
class DigitalClock implements ClockInterface {
constructor(h: number, m: number) { }
tick() {
console.log("beep beep");
}
}
class AnalogClock implements ClockInterface {
constructor(h: number, m: number) { }
tick() {
console.log("tick tock");
}
}
let digital = createClock(DigitalClock, 12, 17);
let analog = createClock(AnalogClock, 7, 32);
So the previous example becomes:
interface AnimalConstructor {
new (): Animal;
}
class Animal {
constructor() {
console.log("Animal");
}
}
class Penguin extends Animal {
constructor() {
super();
console.log("Penguin");
}
}
class Lion extends Animal {
constructor() {
super();
console.log("Lion");
}
}
class Zoo {
AnimalClass: AnimalConstructor // AnimalClass can be 'Lion' or 'Penguin'
constructor(AnimalClass: AnimalConstructor) {
this.AnimalClass = AnimalClass
let Hector = new AnimalClass();
}
}

colspan
I have a solution based on matching the left edge of the td
to the left edge of the corresponding th
. It should handle arbitrarily complex colspans.
I modified the test case to show that arbitrary colspan
is handled correctly.
$(function($) {
"use strict";
// Only part of the demo, the thFromTd call does the work
$(document).on('mouseover mouseout', 'td', function(event) {
var td = $(event.target).closest('td'),
th = thFromTd(td);
th.parent().find('.highlight').removeClass('highlight');
if (event.type === 'mouseover')
th.addClass('highlight');
});
// Returns jquery object
function thFromTd(td) {
var ofs = td.offset().left,
table = td.closest('table'),
thead = table.children('thead').eq(0),
positions = cacheThPositions(thead),
matches = positions.filter(function(eldata) {
return eldata.left <= ofs;
}),
match = matches[matches.length-1],
matchEl = $(match.el);
return matchEl;
}
// Caches the positions of the headers,
// so we don't do a lot of expensive `.offset()` calls.
function cacheThPositions(thead) {
var data = thead.data('cached-pos'),
allth;
if (data)
return data;
allth = thead.children('tr').children('th');
data = allth.map(function() {
var th = $(this);
return {

}).toArray();
thead.data('cached-pos', data);
return data;

Having this problem before I found out my own lazy solution (based on other people suggestions). It should be helpful if your <head>
contents go through php interpreter.
To force downloading file every time you make changes to it, you could add file byte size of this file after question mark sign at the end.
<link rel="stylesheet" type="text/css" href="styles.css?<?=filesize('styles.css');?>">
EDIT: As suggested in comments, filemtime()
is actually a better solution as long as your files have properly updated modify time (I, myself, have experienced such issues in the past, while working with remote files):
<link rel="stylesheet" type="text/css" href="styles.css?<?=filemtime('styles.css');?>">
Here is a very useful and lightweight javascript plugin to accomplish this: js-cookie
Cookies.set('cookieName', 'Value');
setTimeout(function(){
var cookieValue = Cookies.get('cookieName');
if(cookieValue){
console.log("Test Cookie is set!");
} else {
document.write('<p>Sorry, but cookies must be enabled</p>');
}
Cookies.remove('cookieName');
}, 1000);
Works in all browsers, accepts any character.
The time() function displays the seconds between now and the unix epoch , 01 01 1970 (00:00:00 GMT). The strtotime() transforms a normal date format into a time() format. So the representation of that date into seconds will be : 1388516401

If all the other answers do not work for you check the config.inc.php
for the following:
$cfg['Servers'][$i]['host'] = '127.0.0.1';
…and add the port of MySQL set in your XAMPP as shown below:
$cfg['Servers'][$i]['host'] = '127.0.0.1:3307';
Stop MySQL from XAMPP and restart MySQL.
Open a fresh page for http://localhost:8012/phpmyadmin/

According to Mozilla Dev Network, placeholder
is not a valid attribute on a <select>
input.
Instead, add an option with an empty value
and the selected
attribute, as shown below. The empty value
attribute is mandatory to prevent the default behaviour which is to use the contents of the <option>
as the <option>
's value.
<select>
<option value="" selected>select your beverage</option>
<option value="tea">Tea</option>
<option value="coffee">Coffee</option>
<option value="soda">Soda</option>
</select>
In modern browsers, adding the required
attribute to the <select>
element will not allow the user to submit the form which the element is part of if the selected option has an empty value.
If you want to style the default option inside the list (which appears when clicking the element), there's a limited number of CSS properties that are well-supported. color
and background-color
are the 2 safest bets, other CSS properties are likely to be ignored.
In my option the best way (in HTML5) to mark the default option is using the custom data-*
attributes.1 Here's how to style the default option to be greyed out:
select option[data-default] {_x000D_
color: #888;_x000D_
}
_x000D_
<select>_x000D_
<option value="" selected data-default>select your beverage</option>_x000D_
<option value="tea">Tea</option>_x000D_
<option value="coffee">Coffee</option>_x000D_
<option value="soda">Soda</option>_x000D_
</select>
_x000D_
However, this will only style the item inside the drop-down list, not the value displayed on the input. If you want to style that with CSS, target your <select>
element directly. In that case, you can only change the style of the currently selected element at any time.2
If you wanted to make it slightly harder for the user to select the default item, you could set the display: none;
CSS rule on the <option>
, but remember that this will not prevent users from selecting it (using e.g. arrow keys/typing), this just makes it harder for them to do so.
1 This answer previously advised the use of a default
attribute which is non-standard and has no meaning on its own.
2 It's technically possible to style the select itself based on the selected value using JavaScript, but that's outside the scope of this question. This answer, however, covers this method.
in case you do not only need to undo your last query (although your question actually only points on that, I know) and therefore if a transaction might not help you out, you need to implement a workaround for this:
copy the original data before commiting your query and write it back on demand based on the unique id that must be the same in both tables; your rollback-table (with the copies of the unchanged data) and your actual table (containing the data that should be "undone" than). for databases having many tables, one single "rollback-table" containing structured dumps/copies of the original data would be better to use then one for each actual table. it would contain the name of the actual table, the unique id of the row, and in a third field the content in any desired format that represents the data structure and values clearly (e.g. XML). based on the first two fields this third one would be parsed and written back to the actual table. a fourth field with a timestamp would help cleaning up this rollback-table.
since there is no real undo in SQL-dialects despite "rollback" in a transaction (please correct me if I'm wrong - maybe there now is one), this is the only way, I guess, and you have to write the code for it on your own.
I was also having the problem while running the carthage script in the build phase. (Xcode 9) I get that dialog for each and every framework I had added plus the app itself. You can see a very dark shadow growing. I could bypass it by entering the password every time and hitting "Always Allow".
The problem is you defined myList
from main.py
, but subfile.py
needs to use it. Here is a clean way to solve this problem: move all globals to a file, I call this file settings.py
. This file is responsible for defining globals and initializing them:
# settings.py
def init():
global myList
myList = []
Next, your subfile
can import globals:
# subfile.py
import settings
def stuff():
settings.myList.append('hey')
Note that subfile
does not call init()
— that task belongs to main.py
:
# main.py
import settings
import subfile
settings.init() # Call only once
subfile.stuff() # Do stuff with global var
print settings.myList[0] # Check the result
This way, you achieve your objective while avoid initializing global variables more than once.
The filter design method in accepted answer is correct, but it has a flaw. SciPy bandpass filters designed with b, a are unstable and may result in erroneous filters at higher filter orders.
Instead, use sos (second-order sections) output of filter design.
from scipy.signal import butter, sosfilt, sosfreqz
def butter_bandpass(lowcut, highcut, fs, order=5):
nyq = 0.5 * fs
low = lowcut / nyq
high = highcut / nyq
sos = butter(order, [low, high], analog=False, btype='band', output='sos')
return sos
def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
sos = butter_bandpass(lowcut, highcut, fs, order=order)
y = sosfilt(sos, data)
return y
Also, you can plot frequency response by changing
b, a = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = freqz(b, a, worN=2000)
to
sos = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = sosfreqz(sos, worN=2000)
im use this code to and suggest you:
1) sudo sed -i -e 's|disco|eoan|g' /etc/apt/sources.list
2) sudo apt update

In Python 3.x and 2.x you can use use list
to force a copy of the keys to be made:
for i in list(d):
In Python 2.x calling keys
made a copy of the keys that you could iterate over while modifying the dict
:
for i in d.keys():
But note that in Python 3.x this second method doesn't help with your error because keys
returns an a view object instead of copynig the keys into a list.
The Control class has HorizontalContentAlignment and VerticalContentAlignment properties. These properties determine how a control’s content fills the space within the control.
Set HorizontalContentAlignment and VerticalContentAlignment to Center.
In the application I made it was necessary to create a function with multiple options. It's quite large, but it resizes the image, can keep the aspect ratio and can cut of the edges to return only the center of the image:
/// <summary>
/// Resize image with a directory as source
/// </summary>
/// <param name="OriginalFileLocation">Image location</param>
/// <param name="heigth">new height</param>
/// <param name="width">new width</param>
/// <param name="keepAspectRatio">keep the aspect ratio</param>
/// <param name="getCenter">return the center bit of the image</param>
/// <returns>image with new dimentions</returns>
public Image resizeImageFromFile(String OriginalFileLocation, int heigth, int width, Boolean keepAspectRatio, Boolean getCenter)
{
int newheigth = heigth;
System.Drawing.Image FullsizeImage = System.Drawing.Image.FromFile(OriginalFileLocation);
// Prevent using images internal thumbnail
FullsizeImage.RotateFlip(System.Drawing.RotateFlipType.Rotate180FlipNone);
FullsizeImage.RotateFlip(System.Drawing.RotateFlipType.Rotate180FlipNone);
if (keepAspectRatio || getCenter)
{
int bmpY = 0;
double resize = (double)FullsizeImage.Width / (double)width;//get the resize vector
if (getCenter)
{
bmpY = (int)((FullsizeImage.Height - (heigth * resize)) / 2);// gives the Y value of the part that will be cut off, to show only the part in the center
Rectangle section = new Rectangle(new Point(0, bmpY), new Size(FullsizeImage.Width, (int)(heigth * resize)));// create the section to cut of the original image
//System.Console.WriteLine("the section that will be cut off: " + section.Size.ToString() + " the Y value is minimized by: " + bmpY);
Bitmap orImg = new Bitmap((Bitmap)FullsizeImage);//for the correct effect convert image to bitmap.
FullsizeImage.Dispose();//clear the original image
using (Bitmap tempImg = new Bitmap(section.Width, section.Height))
{
Graphics cutImg = Graphics.FromImage(tempImg);// set the file to save the new image to.
cutImg.DrawImage(orImg, 0, 0, section, GraphicsUnit.Pixel);// cut the image and save it to tempImg
FullsizeImage = tempImg;//save the tempImg as FullsizeImage for resizing later
orImg.Dispose();
cutImg.Dispose();
return FullsizeImage.GetThumbnailImage(width, heigth, null, IntPtr.Zero);
}
}
else newheigth = (int)(FullsizeImage.Height / resize);// set the new heigth of the current image
}//return the image resized to the given heigth and width
return FullsizeImage.GetThumbnailImage(width, newheigth, null, IntPtr.Zero);
}
To make it easier to acces the function it's possible to add some overloaded functions:
/// <summary>
/// Resize image with a directory as source
/// </summary>
/// <param name="OriginalFileLocation">Image location</param>
/// <param name="heigth">new height</param>
/// <param name="width">new width</param>
/// <returns>image with new dimentions</returns>
public Image resizeImageFromFile(String OriginalFileLocation, int heigth, int width)
{
return resizeImageFromFile(OriginalFileLocation, heigth, width, false, false);
}
/// <summary>
/// Resize image with a directory as source
/// </summary>
/// <param name="OriginalFileLocation">Image location</param>
/// <param name="heigth">new height</param>
/// <param name="width">new width</param>
/// <param name="keepAspectRatio">keep the aspect ratio</param>
/// <returns>image with new dimentions</returns>
public Image resizeImageFromFile(String OriginalFileLocation, int heigth, int width, Boolean keepAspectRatio)
{
return resizeImageFromFile(OriginalFileLocation, heigth, width, keepAspectRatio, false);
}
Now are the last two booleans optional to set. Call the function like this:
System.Drawing.Image ResizedImage = resizeImageFromFile(imageLocation, 800, 400, true, true);
Two simple examples to capture output the pwd
command:
$ b=$(pwd)
$ echo $b
/home/user1
or
$ a=`pwd`
$ echo $a
/home/user1
The first way is preferred. Note that there can't be any spaces after the =
for this to work.
Example using a short script:
#!/bin/bash
echo "hi there"
then:
$ ./so.sh
hi there
$ a=$(so.sh)
$ echo $a
hi there
In general a more flexible approach would be to return an exit value from the command and use it for further processing, though sometimes we just may want to capture the simple output from a command.
Remove files from the index, or from the working tree and the index. git rm will not remove a file from just your working directory.
Here's how you might delete a file using rm -f
and then remove it from your index with git rm
$ rm -f index.html
$ git status -s
D index.html
$ git rm index.html
rm 'index.html'
$ git status -s
D index.html
However you can do this all in one go with just git rm
$ git status -s
$ git rm index.html
rm 'index.html'
$ ls
lib vendor
$ git status -s
D index.html

Quick fix: Change how excel converts imported files. Go to 'File', then 'Options', then 'Advanced'. Scroll down and uncheck 'Use system seperators'. Also change 'Decimal separator' to '.' and 'Thousands separator' to ',' . Then simply 're-save' your file in the CSV (Comma delimited) format. The root cause is usually associated with how the csv file is created. Trust that helps. Point is, why use extra code if not necessary? Cross-platform understanding and integration is key in engineering/development.
You can run nodejs using pm2 if you want to manage each microservice means and run it. Node will be running in a port right just configure that port in nginx(/etc/nginx/sites-enabled/domain.com)
server{
listen 80;
server_name domain.com www.domain.com;
location / {
return 403;
}
location /url {
proxy_pass http://localhost:51967/info;
}
}
Check whether localhost is running or not by using ping.
And
Create one single Node.js server which handles all Node.js requests. This reads the requested files and evals their contents. So the files are interpreted on each request, but the server logic is much simpler.
This is best and as you said easier too
You could do:
sub("*\\.[0-9]", "", a)
or
library(stringr)
str_sub(a, start=1, end=-3)
You should call plt.show()
only at the end after creating all the plots.
For Eclipse in Macbook it is just 2 click process:
EDIT:
Those three different elements all have different rendering rules.
So for:
table#bar
you need to set the width to 100% otherwise it will be only be as wide as it determines it needs to be. However, if the table rows total width is greater than the width of bar
it will expand to its needed width. IF i recall you can counteract this by setting display: block !important;
though its been awhile since ive had to fix that. (im sure someone will correct me if im wrong).
textarea#bar
i beleive is a block level element so it will follow the rules the same as the div. The only caveat here is that textarea
take an attributes of cols
and rows
which are measured in character columns. If this is specified on the element it will override the width specified by the css.
input#bar
is an inline element, so by default you cant assign it width. However the similar to textarea
's cols
attribute, it has a size
attribute on the element that can determine width. That said, you can always specifiy a width by using display: block;
in your css for it. Then it will follow the same rendering rules as the div.
td#foo
will be rendered as a table-cell
which has some craziness to it. Bottom line here is that for your purposes its going to act just like div#foo
as far as restricting the width of its contents. The only issue here is going to be potential unwrappable text in the column somewhere which would make it ignore your width setting. Also all cells in the column are going to get the width of the widest cell.
Thats the default behavior of block level element - ie. if width is auto
(the default) then it will be 100% of the inner width of the containing element. so in essence:
#foo {width: 800px;}
#bar {padding-left: 2px; padding-right: 2px; margin-left: 2px; margin-right: 2px;}
will give you exactly what you want.
find the numbers and then replaced with strings which specified. It is achieved by two methods
Using a regular expression literal
Using keyword RegExp object
Using a regular expression literal:
<script type="text/javascript">
var string = "my contact number is 9545554545. my age is 27.";
alert(string.replace(/\d+/g, "XXX"));
</script>
**Output:**my contact number is XXX. my age is XXX.

I would like to say that you must always use jQuery latest or recent stable versions. However if you need to do some work with others versions then you can add that version and renamed the $
to some other name. For instance
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
<script>var $oldjQuery = $.noConflict(true);</script>
Look here if you write something using $
then you will get the latest version. But if you need to do anything with old then just use$oldjQuery
instead of $
.
Here is an example
$(function(){console.log($.fn.jquery)});
$oldjQuery (function(){console.log($oldjQuery.fn.jquery)})
With Git 2.25 (Q1 2020), you can modify it.
See "Git submodule url changed" and the new command
git submodule set-url [--] <path> <newurl>
Original answer (May 2009, ten years ago)
Actually, a patch has been submitted in April 2009 to clarify gitmodule
role.
So now the gitmodule documentation does not yet include:
The
.gitmodules
file, located in the top-level directory of a git working tree, is a text file with a syntax matching the requirements -of linkgit:git-config1.
[NEW]:
As this file is managed by Git, it tracks the +records of a project's submodules.
Information stored in this file is used as a hint to prime the authoritative version of the record stored in the project configuration file.
User specific record changes (e.g. to account for differences in submodule URLs due to networking situations) should be made to the configuration file, while record changes to be propagated (e.g. +due to a relocation of the submodule source) should be made to this file.
That pretty much confirm Jim's answer.
If you follow this git submodule tutorial, you see you need a "git submodule init
" to add the submodule repository URLs to .git/config.
"git submodule sync
" has been added in August 2008 precisely to make that task easier when URL changes (especially if the number of submodules is important).
The associate script with that command is straightforward enough:
module_list "$@" |
while read mode sha1 stage path
do
name=$(module_name "$path")
url=$(git config -f .gitmodules --get submodule."$name".url)
if test -e "$path"/.git
then
(
unset GIT_DIR
cd "$path"
remote=$(get_default_remote)
say "Synchronizing submodule url for '$name'"
git config remote."$remote".url "$url"
)
fi
done
The goal remains: git config remote."$remote".url "$url"

To directly answer your two subquestions: No, you cannot do this with Ajax, nor can you calculate it with PHP.
What I have done in the past is use a trigger from the iframe'd page in window.onload
(NOT domready
, as it can take a while for images to load) to pass the page's body height to the parent.
<body onload='parent.resizeIframe(document.body.scrollHeight)'>
Then the parent.resizeIframe
looks like this:
function resizeIframe(newHeight)
{
document.getElementById('blogIframe').style.height = parseInt(newHeight,10) + 10 + 'px';
}
Et voila, you have a robust resizer that triggers once the page is fully rendered with no nasty contentdocument
vs contentWindow
fiddling :)
Sure, now people will see your iframe at default height first, but this can be easily handled by hiding your iframe at first and just showing a 'loading' image. Then, when the resizeIframe
function kicks in, put two extra lines in there that will hide the loading image, and show the iframe for that faux Ajax look.
Of course, this only works from the same domain, so you may want to have a proxy PHP script to embed this stuff, and once you go there, you might as well just embed your blog's RSS feed directly into your site with PHP.
SELECT CASE WHEN field IS NULL THEN 'Empty' ELSE field END AS field_alias
Or more idiomatic:
SELECT coalesce(field, 'Empty') AS field_alias
In your template
template <void (*T)(int &)>
void doOperation()
The parameter T
is a non-type template parameter. This means that the behaviour of the template function changes with the value of the parameter (which must be fixed at compile time, which function pointer constants are).
If you want somthing that works with both function objects and function parameters you need a typed template. When you do this, though, you also need to provide an object instance (either function object instance or a function pointer) to the function at run time.
template <class T>
void doOperation(T t)
{
int temp=0;
t(temp);
std::cout << "Result is " << temp << std::endl;
}
There are some minor performance considerations. This new version may be less efficient with function pointer arguments as the particular function pointer is only derefenced and called at run time whereas your function pointer template can be optimized (possibly the function call inlined) based on the particular function pointer used. Function objects can often be very efficiently expanded with the typed template, though as the particular operator()
is completely determined by the type of the function object.
You could use the "Shown" event: MSDN - Form.Shown
"The Shown event is only raised the first time a form is displayed; subsequently minimizing, maximizing, restoring, hiding, showing, or invalidating and repainting will not raise this event."
Provided that the remote repository is origin
, and that you're interested in branch_name
:
git fetch origin
git reset --hard origin/<branch_name>
Also, you go for reset the current branch of origin
to HEAD
.
git fetch origin
git reset --hard origin/HEAD
How it works:
git fetch origin
downloads the latest from remote without trying to merge or rebase anything.
Then the git reset
resets the <branch_name>
branch to what you just fetched. The --hard
option changes all the files in your working tree to match the files in origin/branch_name
.
The problem is that .NET will always round a double
to 15 significant decimal digits before applying your formatting, regardless of the precision requested by your format and regardless of the exact decimal value of the binary number.
I'd guess that the Visual Studio debugger has its own format/display routines that directly access the internal binary number, hence the discrepancies between your C# code, your C code and the debugger.
There's nothing built-in that will allow you to access the exact decimal value of a double
, or to enable you to format a double
to a specific number of decimal places, but you could do this yourself by picking apart the internal binary number and rebuilding it as a string representation of the decimal value.
Alternatively, you could use Jon Skeet's DoubleConverter
class (linked to from his "Binary floating point and .NET" article). This has a ToExactString
method which returns the exact decimal value of a double
. You could easily modify this to enable rounding of the output to a specific precision.
double i = 10 * 0.69;
Console.WriteLine(DoubleConverter.ToExactString(i));
Console.WriteLine(DoubleConverter.ToExactString(6.9 - i));
Console.WriteLine(DoubleConverter.ToExactString(6.9));
// 6.89999999999999946709294817992486059665679931640625

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.
If your project uses Maven you can simply include UCanAccess via the following coordinates:
groupId: net.sf.ucanaccess
artifactId: ucanaccess
The following is an excerpt from pom.xml
, you may need to update the <version>
to get the most recent release:
<dependencies>
<dependency>
<groupId>net.sf.ucanaccess</groupId>
<artifactId>ucanaccess</artifactId>
<version>4.0.4</version>
</dependency>
</dependencies>
As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:
UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)
Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like
ucanaccess-4.0.1.jar
/lib/
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.1.6.jar
All you need to do is add all five (5) JARs to your project.
NOTE: Do not add
loader/ucanload.jar
to your build path if you are adding the other five (5) JAR files. TheUcanloadDriver
class is only used in special circumstances and requires a different setup. See the related answer here for details.
Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path...
. Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this
NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.
After adding all five (5) JAR files the "Libraries" folder should look something like this:
IntelliJ IDEA: Choose File > Project Structure...
from the main menu. In the "Libraries" pane click the "Add" (+
) button and add the five (5) JAR files. Once that is done the project should look something like this:
Now "U Can Access" data in .accdb and .mdb files using code like this
// assumes...
// import java.sql.*;
Connection conn=DriverManager.getConnection(
"jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
System.out.println(rs.getString(1));
}
At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.
I was recieving the same error when I was tring to call an object element by using another objects return value like;
$this->array1 = a json table which returns country codes of the ip
$this->array2 = a json table which returns languages of the country codes
$this->array2->$this->array1->country;// Error line
The above code was throwing the error and I tried many ways to fix it like; calling this part $this->array1->country
in another function as return value, (string)
, taking it into quotations etc. I couldn't even find the solution on the web then i realised that the solution was very simple. All you have to do it wrap it with curly brackets and that allows you to target an object with another object's element value. like;
$this->array1 = a json table which returns country codes of the ip
$this->array2 = a json table which returns languages of the country codes
$this->array2->{$this->array1->country};
If anyone facing the same and couldn't find the answer, I hope this can help because i spend a night for this simple solution =)
This is how you can insert into an identity column:
CREATE TABLE my_table (id INTEGER PRIMARY KEY AUTOINCREMENT, name COLLATE NOCASE);
CREATE TABLE temp_table (name COLLATE NOCASE);
.import predefined/myfile.txt temp_table
insert into my_table (name) select name from temp_table;
myfile.txt is a file in C:\code\db\predefined\
data.db is in C:\code\db\
myfile.txt contains strings separated by newline character.
If you want to add more columns, it's easier to separate them using the pipe character, which is the default.
Let's pretend you were to give me a potentially long-running task: get the names of the first five unique people you come across. This might take days if I'm in a sparsely populated area. You're not really interested in sitting on your hands while I'm running around so you say, "When you've got the list, call me on my cell and read it back to me. Here's the number.".
You've given me a callback reference--a function that I'm supposed to execute in order to hand off further processing.
In JavaScript it might look something like this:
var lottoNumbers = [];
var callback = function(theNames) {
for (var i=0; i<theNames.length; i++) {
lottoNumbers.push(theNames[i].length);
}
};
db.executeQuery("SELECT name " +
"FROM tblEveryOneInTheWholeWorld " +
"ORDER BY proximity DESC " +
"LIMIT 5", callback);
while (lottoNumbers.length < 5) {
playGolf();
}
playLotto(lottoNumbers);
This could probably be improved in lots of ways. E.g., you could provide a second callback: if it ends up taking longer than an hour, call the red phone and tell the person that answers that you've timed out.
var json = jQuery.parseJSON(s); //If you have jQuery.
Since the comment looks cluttered, please use the parse function after enclosing those square brackets inside the quotes.
var s=['{"Select":"11","PhotoCount":"12"}','{"Select":"21","PhotoCount":"22"}'];
Change the above code to
var s='[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';
Eg:
$(document).ready(function() {
var s= '[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';
s = jQuery.parseJSON(s);
alert( s[0]["Select"] );
});
And then use the parse function. It'll surely work.
EDIT :Extremely sorry that I gave the wrong function name. it's jQuery.parseJSON
Edit (30 April 2020):
Editing since I got an upvote for this answer. There's a browser native function available instead of JQuery (for nonJQuery users), JSON.parse("<json string here>")
You need to edit your ~/.ssh/config file. Add something like the following:
Host example.com
Port 1234
A quick google search shows a few different resources that explain it in more detail than me.

header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header("Content-Disposition: attachment;filename=\"filename.xlsx\"");
header("Cache-Control: max-age=0");
According to @Enno Gröper 's post, I've tried the SSLContext constructor and it works well on my machine. code as below:
import ssl
ctx = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
urllib2.urlopen("https://your-test-server.local", context=ctx)
if you need opener, just added this context like:
opener = urllib2.build_opener(urllib2.HTTPSHandler(context=ctx))
NOTE: all above test environment is python 2.7.12. I use PROTOCOL_SSLv23 here since the doc says so, other protocol might also works but depends on your machine and remote server, please check the doc for detail.
A combination of answers worked for me

Not sure if I'm missing something here but can't you just convert the timestamp like this:
CONVERT(VARCHAR,CAST(ZEIT AS DATETIME), 110)
Using DateTimeFormatter it can be achieved as below:
import java.text.SimpleDateFormat;
import java.time.LocalDateTime;
import java.time.ZoneOffset;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;
import java.time.temporal.TemporalAccessor;
import java.util.Date;
import java.util.TimeZone;
public class DateTimeFormatTest {
public static void main(String[] args) {
String pattern = "[yyyy-MM-dd[['T'][ ]HH:mm:ss[.SSSSSSSz][.SSS[XXX][X]]]]";
String timeSample = "2018-05-04T13:49:01.7047141Z";
SimpleDateFormat simpleDateFormatter = new SimpleDateFormat("dd/MM/yy HH:mm:ss");
DateTimeFormatter formatter = DateTimeFormatter.ofPattern(pattern);
TemporalAccessor accessor = formatter.parse(timeSample);
ZonedDateTime zTime = LocalDateTime.from(accessor).atZone(ZoneOffset.UTC);
Date date=new Date(zTime.toEpochSecond()*1000);
simpleDateFormatter.setTimeZone(TimeZone.getTimeZone(ZoneOffset.UTC));
System.out.println(simpleDateFormatter.format(date));
}
}
Pay attention at String pattern
, this is the combination of multiple patterns. In open [
and close ]
square brackets you can mention any kind of patterns.

Don't use regexes, use BeautifulSoup. That, or be so crufty as to spawn it out to, say, w3m/lynx and pull back in what w3m/lynx renders. First is more elegant probably, second just worked a heck of a lot faster on some unoptimized code I wrote a while back.
As previously mentioned: Classes are reference type while Structs are value types with all the consequences.
As a thumb of rule Framework Design Guidelines recommends using Structs instead of classes if:
In your 'head' section, add this code:
<style>
input[type='text'] { font-size: 24px; }
</style>
Or you can only add the:
input[type='text'] { font-size: 24px; }
to a CSS file which can later be included.
You can also change the font face by using the CSS property: font-family
font-family: monospace;
So you can have a CSS code like this:
input[type='text'] { font-size: 24px; font-family: monospace; }
You can find further help at the W3Schools website.
I suggest you to have a look at the CSS3 specification. With CSS3 you can also load a font from the web instead of having the limitation to use only the most common fonts or tell the user to download the font you're using.
Xfce/Thunar solution is basically the same as Gnome/Nautilus:
Simply type sftp://yourhost/
to address line in Thunar (You can get there by Ctrl + L)
(The authorization is identical to ssh
/scp
, i.e. with proper use of ~/.ssh/config
, keys and ssh-agent, you can achieve decent ease and security: server alias + no passwords asked.)

Try this:
onclick="myfunction(
'/myController/myAction',
function(){myfuncionOnOK('/myController2/myAction2','myParameter2');},
function(){myfuncionOnCancel('/myController3/myAction3','myParameter3');}
);"
Then you just need to call these two functions passed to myfunction
:
function myfunction(url, f1, f2) {
// …
f1();
f2();
}
Try replacing the appropriate lines with:
myStringArray[0][x-1] = "a string";
myStringArray[0][y-1] = "another string";
Your code is incorrect because the sub-arrays have a length of y
, and indexing starts at 0. So setting to myStringArray[0][y]
or myStringArray[0][x]
will fail because the indices x
and y
are out of bounds.
String[][] myStringArray = new String [x][y];
is the correct way to initialise a rectangular multidimensional array. If you want it to be jagged (each sub-array potentially has a different length) then you can use code similar to this answer. Note however that John's assertion that you have to create the sub-arrays manually is incorrect in the case where you want a perfectly rectangular multidimensional array.
The error is try to fix a Youtube error.
The solution to avoid your Javascript-Console-Error complex is to accept that Youtube (and also other webpages) can have Javascript errors that you can't fix.
That is all.
I think this might be the simplest solution:
<tr onclick="location.href='http://www.mywebsite.com'" style="cursor: pointer">
<td>...</td>
<td>...</td>
</tr>
The cursor CSS property sets the type of cursor, if any, to show when the mouse pointer is over an element.
The inline css defines that for that element the cursor will be formatted as a pointer, so you don't need the 'hover'.
There's no concise way to directly manipulate the "keys" of a Javascript object. It's not really designed for that. Do you have the freedom to put your data in something better than a regular object (or an Array, as your sample code suggests)?
If so, and if your question could be rephrased as "What dictionary-like object should I use if I want to iterate over the keys in sorted order?" then you might develop an object like this:
var a = {
keys : new Array(),
hash : new Object(),
set : function(key, value) {
if (typeof(this.hash[key]) == "undefined") { this.keys.push(key); }
this.hash[key] = value;
},
get : function(key) {
return this.hash[key];
},
getSortedKeys : function() {
this.keys.sort();
return this.keys;
}
};
// sample use
a.set('b',1);
a.set('z',1);
a.set('a',1);
var sortedKeys = a.getSortedKeys();
for (var i in sortedKeys) { print(sortedKeys[i]); }
If you have no control over the fact that the data is in a regular object, this utility would convert the regular object to your fully-functional dictionary:
a.importObject = function(object) {
for (var i in object) { this.set(i, object); }
};
This was a object definition (instead of a reusable constructor function) for simplicity; edit at will.
Your program will continue with the second if
statement in the case of y == x
, causing a ZeroDivisionError
. You need to make the statements mutually exclusive; the way to do that is to use elif
("else if") instead of if
:
import math
x = int(input("Enter a value for x: "))
y = int(input("Enter a value for y: "))
if y == x:
print(1)
elif y == 1: # see georg's comment
print(x)
elif y > x: # will be executed only if y != 1 and y != x
print(0)
else: # will be executed only if y != 1 and y != x and x <= y
a = math.factorial(x)
b = math.factorial(y)
c = math.factorial(x-y) # that appears to be useful to get the correct result
div = a // (b * c)
print(div)
Here's a workaround for Binding Columns in the DataGrid. Since the Columns property is ReadOnly, like everyone noticed, I made an Attached Property called BindableColumns which updates the Columns in the DataGrid everytime the collection changes through the CollectionChanged event.
If we have this Collection of DataGridColumn's
public ObservableCollection<DataGridColumn> ColumnCollection
{
get;
private set;
}
Then we can bind BindableColumns to the ColumnCollection like this
<DataGrid Name="dataGrid"
local:DataGridColumnsBehavior.BindableColumns="{Binding ColumnCollection}"
AutoGenerateColumns="False"
...>
The Attached Property BindableColumns
public class DataGridColumnsBehavior
{
public static readonly DependencyProperty BindableColumnsProperty =
DependencyProperty.RegisterAttached("BindableColumns",
typeof(ObservableCollection<DataGridColumn>),
typeof(DataGridColumnsBehavior),
new UIPropertyMetadata(null, BindableColumnsPropertyChanged));
private static void BindableColumnsPropertyChanged(DependencyObject source, DependencyPropertyChangedEventArgs e)
{
DataGrid dataGrid = source as DataGrid;
ObservableCollection<DataGridColumn> columns = e.NewValue as ObservableCollection<DataGridColumn>;
dataGrid.Columns.Clear();
if (columns == null)
{
return;
}
foreach (DataGridColumn column in columns)
{
dataGrid.Columns.Add(column);
}
columns.CollectionChanged += (sender, e2) =>
{
NotifyCollectionChangedEventArgs ne = e2 as NotifyCollectionChangedEventArgs;
if (ne.Action == NotifyCollectionChangedAction.Reset)
{
dataGrid.Columns.Clear();
foreach (DataGridColumn column in ne.NewItems)
{
dataGrid.Columns.Add(column);
}
}
else if (ne.Action == NotifyCollectionChangedAction.Add)
{
foreach (DataGridColumn column in ne.NewItems)
{
dataGrid.Columns.Add(column);
}
}
else if (ne.Action == NotifyCollectionChangedAction.Move)
{
dataGrid.Columns.Move(ne.OldStartingIndex, ne.NewStartingIndex);
}
else if (ne.Action == NotifyCollectionChangedAction.Remove)
{
foreach (DataGridColumn column in ne.OldItems)
{
dataGrid.Columns.Remove(column);
}
}
else if (ne.Action == NotifyCollectionChangedAction.Replace)
{
dataGrid.Columns[ne.NewStartingIndex] = ne.NewItems[0] as DataGridColumn;
}
};
}
public static void SetBindableColumns(DependencyObject element, ObservableCollection<DataGridColumn> value)
{
element.SetValue(BindableColumnsProperty, value);
}
public static ObservableCollection<DataGridColumn> GetBindableColumns(DependencyObject element)
{
return (ObservableCollection<DataGridColumn>)element.GetValue(BindableColumnsProperty);
}
}
I found the answer to may previous post. Here it is.
CREATE TABLE #TempTable (id int)
INSERT INTO @TestTable (col1, col2) OUTPUT INSERTED.id INTO #TempTable select 1,2
INSERT INTO @TestTable (col1, col2) OUTPUT INSERTED.id INTO #TempTable select 3,4
SELECT * FROM #TempTable --this select will chage @@ROWCOUNT value
You can't remove, nor can you add to a fixed-size-list of Arrays.
But you can create your sublist from that list.
list = list.subList(0, list.size() - (list.size() - count));
public static String SelectRandomFromTemplate(String template, int count) {
String[] split = template.split("\\|");
List<String> list = Arrays.asList(split);
Random r = new Random();
while( list.size() > count ) {
list = list.subList(0, list.size() - (list.size() - count));
}
return StringUtils.join(list, ", ");
}
*Other way is
ArrayList<String> al = new ArrayList<String>(Arrays.asList(template));
this will create ArrayList which is not fixed size like Arrays.asList
Best Solution
The only difference is
1.Mutex -> lock and unlock are under the ownership of a thread that locks the mutex.
2.Semaphore -> No ownership i.e; if one thread calls semwait(s) any other thread can call sempost(s) to remove the lock.
please try this way with filter
angular.module('myApp')
.filter('isEmpty', function () {
var bar;
return function (obj) {
for (bar in obj) {
if (obj.hasOwnProperty(bar)) {
return false;
}
}
return true;
};
});
usage:
<p ng-hide="items | isEmpty">Some Content</p>
Via from : Checking if object is empty, works with ng-show but not from controller?
Teylyn's answer worked great for me, but I had to modify it a bit to get proper results. I want to provide an extended explanation for whoever would need it.
My setup was as follows:
I put the following formula in cell A1 of Sheet3:
=iferror(vlookup(Sheet1!A$1;Sheet2!$A$1:$D$50;column(A1);false);Sheet1!A1)
Read this as follows: Take the value of the first column in Sheet1 (old data). Look up in Sheet2 (updated rows). If present, output the value from the indicated column in Sheet2. On error, output the value for the current column of Sheet1.
Notes:
In my version of the formula, ";" is used as parameter separator instead of ",". That is because I am located in Europe and we use the "," as decimal separator. Change ";" back to "," if you live in a country where "." is the decimal separator.
A$1: means always take column 1 when copying the formula to a cell in a different column. $A$1 means: always take the exact cell A1, even when copying the formula to a different row or column.
After pasting the formula in A1, I extended the range to columns B, C, etc., until the full width of my table was reached. Because of the $-signs used, this gives the following formula's in cells B1, C1, etc.:
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(B1);FALSE);'Sheet1'!B1)
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(C1);FALSE);'Sheet1'!C1)
and so forth. Note that the lookup is still done in the first column. This is because VLOOKUP needs the lookup data to be sorted on the column where the lookup is done. The output column is however the column where the formula is pasted.
Next, select a rectangle in Sheet 3 starting at A1 and having the size of the data in Sheet1 (same number of rows and columns). Press Ctrl-D to copy the formulas of the first row to all selected cells.
Cells A2, A3, etc. will get these formulas:
=IFERROR(VLOOKUP('Sheet1'!$A2;'Sheet2'!$A$1:$D$50;COLUMN(A2);FALSE);'Sheet1'!A2)
=IFERROR(VLOOKUP('Sheet1'!$A3;'Sheet2'!$A$1:$D$50;COLUMN(A3);FALSE);'Sheet1'!A3)
Because of the use of $-signs, the lookup area is constant, but input data is used from the current row.
Just Use
import qs from "qs";
let data = {
'profileId': this.props.screenProps[0],
'accountId': this.props.screenProps[1],
'accessToken': this.props.screenProps[2],
'itemId': this.itemId
};
return axios.post(METHOD_WALL_GET, qs.stringify(data))
To solve this issue on my side, I had to use a combo of what was already proposed there
DECLARE
chunk1 CLOB; chunk2 CLOB; chunk3 CLOB;
BEGIN
chunk1 := 'very long literal part 1';
chunk2 := 'very long literal part 2';
chunk3 := 'very long literal part 3';
INSERT INTO table (MY_CLOB)
SELECT ( chunk1 || chunk2 || chunk3 ) FROM dual;
END;
Hope this helps.
Try:
SELECT convert(datetime, '23/07/2009', 103)
this is British/French standard.
'a' in x
and a quick search reveals some nice information about it: http://docs.python.org/3/tutorial/datastructures.html#dictionaries
This (mysql_connect, mysql_...) extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used.
(ref: http://php.net/manual/en/function.mysql-connect.php)
Object Oriented:
$mysqli = new mysqli("host", "user", "password");
$mysqli->select_db("db");
Procedural:
$link = mysqli_connect("host","user","password") or die(mysqli_error($link));
mysqli_select_db($link, "db");
function displayArrayValue($array,$key) {
if (array_key_exists($key,$array)) echo "$key is at ".$array[$key];
}
displayArrayValue($page, "Service");
Here is what you can use to disable certain column to be disabled:
$('#tableId').dataTable({
"columns": [
{ "data": "id"},
{ "data": "sampleSortableColumn" },
{ "data": "otherSortableColumn" },
{ "data": "unsortableColumn", "orderable": false}
]
});
So all you have to do is add the "orderable": false to the column you don't want to be sortable.
Just add a >NUL
at the end of the lines producing the messages.
For example,
COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat >NUL
char*
is a mutable pointer to a mutable character/string.
const char*
is a mutable pointer to an immutable character/string. You cannot change the contents of the location(s) this pointer points to. Also, compilers are required to give error messages when you try to do so. For the same reason, conversion from const char *
to char*
is deprecated.
char* const
is an immutable pointer (it cannot point to any other location) but the contents of location at which it points are mutable.

You can make you request headers by yourself using:
// open a socket connection on port 80
$fp = fsockopen($host, 80);
// send the request headers:
fputs($fp, "POST $path HTTP/1.1\r\n");
fputs($fp, "Host: $host\r\n");
fputs($fp, "Referer: $referer\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ". strlen($data) ."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $data);
$result = '';
while(!feof($fp)) {
// receive the results of the request
$result .= fgets($fp, 128);
}
// close the socket connection:
fclose($fp);
Like writen on how make request

There are two attributes, namely readonly
and disabled
, that can make a semi-read-only input. But there is a tiny difference between them.
<input type="text" readonly />
<input type="text" disabled />
readonly
attribute makes your input text disabled, and users are not able to change it anymore.disabled
attribute make your input-text disabled(unchangeable) but also cannot it be submitted.jQuery approach (1):
$("#inputID").prop("readonly", true);
$("#inputID").prop("disabled", true);
jQuery approach (2):
$("#inputID").attr("readonly","readonly");
$("#inputID").attr("disabled", "disabled");
JavaScript approach:
document.getElementById("inputID").readOnly = true;
document.getElementById("inputID").disabled = true;

join() is a instance method of java.lang.Thread class which we can use join() method to ensure all threads that started from main must end in order in which they started and also main should end in last. In other words waits for this thread to die.
Exception: join() method throws InterruptedException.
Thread state: When join() method is called on thread it goes from running to waiting state. And wait for thread to die.
synchronized block: Thread need not to acquire object lock before calling join() method i.e. join() method can be called from outside synchronized block.
Waiting time: join(): Waits for this thread to die.
public final void join() throws InterruptedException;
This method internally calls join(0). And timeout of 0 means to wait forever;
join(long millis) – synchronized method Waits at most millis milliseconds for this thread to die. A timeout of 0 means to wait forever.
public final synchronized void join(long millis)
throws InterruptedException;
public final synchronized void join(long millis, int nanos)
throws InterruptedException;
Example of join method
class MyThread implements Runnable {
public void run() {
String threadName = Thread.currentThread().getName();
Printer.print("run() method of "+threadName);
for(int i=0;i<4;i++){
Printer.print("i="+i+" ,Thread="+threadName);
}
}
}
public class TestJoin {
public static void main(String...args) throws InterruptedException {
Printer.print("start main()...");
MyThread runnable = new MyThread();
Thread thread1=new Thread(runnable);
Thread thread2=new Thread(runnable);
thread1.start();
thread1.join();
thread2.start();
thread2.join();
Printer.print("end main()");
}
}
class Printer {
public static void print(String str) {
System.out.println(str);
}
}
Output:
start main()...
run() method of Thread-0
i=0 ,Thread=Thread-0
i=1 ,Thread=Thread-0
i=2 ,Thread=Thread-0
i=3 ,Thread=Thread-0
run() method of Thread-1
i=0 ,Thread=Thread-1
i=1 ,Thread=Thread-1
i=2 ,Thread=Thread-1
i=3 ,Thread=Thread-1
end main()
Note: calling thread1.join() made main thread to wait until Thread-1 dies.
Let’s check a program to use join(long millis)
First, join(1000) will be called on Thread-1, but once 1000 millisec are up, main thread can resume and start thread2 (main thread won’t wait for Thread-1 to die).
class MyThread implements Runnable {
public void run() {
String threadName = Thread.currentThread().getName();
Printer.print("run() method of "+threadName);
for(int i=0;i<4;i++){
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
Printer.print("i="+i+" ,Thread="+threadName);
}
}
}
public class TestJoin {
public static void main(String...args) throws InterruptedException {
Printer.print("start main()...");
MyThread runnable = new MyThread();
Thread thread1=new Thread(runnable);
Thread thread2=new Thread(runnable);
thread1.start();
// once 1000 millisec are up,
// main thread can resume and start thread2.
thread1.join(1000);
thread2.start();
thread2.join();
Printer.print("end main()");
}
}
class Printer {
public static void print(String str) {
System.out.println(str);
}
}
Output:
start main()...
run() method of Thread-0
i=0 ,Thread=Thread-0
run() method of Thread-1
i=1 ,Thread=Thread-0
i=2 ,Thread=Thread-0
i=0 ,Thread=Thread-1
i=1 ,Thread=Thread-1
i=3 ,Thread=Thread-0
i=2 ,Thread=Thread-1
i=3 ,Thread=Thread-1
end main()

If you look at the side bar of your question, you will see many related questions...
In your context, the simpler method might be to install a PDF print driver like PDFCreator and just print the page to this output.
@snowBlind In the first example you gave, your style rules should go in a <style> tag, not a <script> tag:
<style type="text/css">
.center {
margin: 0 auto;
}
</style>
Also, I tried the changes that were mentioned in this answer (see results at http://jsfiddle.net/8cXqQ/7/), but they still don't appear to work.
You can surround the video with a div and apply width and auto margins to the div to center the video (along with specifying width attribute for video, see results at http://jsfiddle.net/8cXqQ/9/).
But that doesn't seem like the simplest solution...shouldn't we be able to center a video without having to wrap it in a container div?
In newer hibernate jars, you can find the required jpa file under "hibernate-search-5.8.0.Final\dist\lib\provided\hibernate-jpa-2.1-api-1.0.0.Final". You have to add this jar file into your project java build path. This will most probably solve the issue.
You have a scalar valued function as opposed to a table valued function. The from clause is used for tables. Just query the value directly in the column list.
select dbo.fun_functional_score('01091400003')
Windows Subsystem for Linux did not exist when this question was asked. It gave these results in my test:
uname -s -> Linux
uname -o -> GNU/Linux
uname -r -> 4.4.0-17763-Microsoft
This means that you need uname -r to distinguish it from native Linux.
It's even simpler than that. Just did this (on Windows, but it should work on other OS):
Git just sees you added a directory and renamed a bunch of files. No biggie.
Your screenshot shows you doing a pip install
from the python terminal which is wrong. Do that outside the python terminal. Also the package I believe you want is:
pip install opencv-python
Since you're running on Windows, I might look at the official install manual: https://breakthrough.github.io/Installing-OpenCV
opencv2 is ONLY compatible with Python3 if you do so by compiling the source code. See the section under opencv supported python versions: https://pypi.org/project/opencv-python

Restarting the SQL Server will clear up the log space used by your database. If this however is not an option, you can try the following:
* Issue a CHECKPOINT command to free up log space in the log file.
* Check the available log space with DBCC SQLPERF('logspace'). If only a small
percentage of your log file is actually been used, you can try a DBCC SHRINKFILE
command. This can however possibly introduce corruption in your database.
* If you have another drive with space available you can try to add a file there in
order to get enough space to attempt to resolve the issue.
Hope this will help you in finding your solution.

Here is the typical structure of new Codeigniter project:
- application/

I usually use this code in my CI index.php. Just change local_server_name to the name of your local webserver.
With this code you can deploy your site to your production server without changing index.php each time.

define('ENVIRONMENT', 'development');
} else {
define('ENVIRONMENT', 'production');

switch (ENVIRONMENT) {
case 'development':
error_reporting(E_ALL);

Ternary Operator always returns a value. So in situation when you want some output value from result and there are only 2 conditions always better to use ternary operator. Use if-else if any of the above mentioned conditions are not true.
I believe it causes the standard event to not happen.
In your example the browser will not attempt to go to #.
The nuclear option:
$("#yourtableid").html("");
Destroys everything inside of #yourtableid
. Be careful with your selectors, as it will destroy any html in the selector you pass!
Manoj answer above is correct, but another option is to use MESSAGE.encode() or encode('utf-8') to convert to bytes. bytes and encode are mostly the same, encode is compatible with python 2. see here for more
full code:
import socket
UDP_IP = "127.0.0.1"
UDP_PORT = 5005
MESSAGE = "Hello, World!"
print("UDP target IP: %s" % UDP_IP)
print("UDP target port: %s" % UDP_PORT)
print("message: %s" % MESSAGE)
sock = socket.socket(socket.AF_INET, # Internet
socket.SOCK_DGRAM) # UDP
sock.sendto(MESSAGE.encode(), (UDP_IP, UDP_PORT))
For windows first set variables:
set JPDA_ADDRESS=8000
set JPDA_TRANSPORT=dt_socket
to start server in debug mode:
%TOMCAT_HOME%/bin/catalina.bat jpda start
For unix first export variables:
export JPDA_ADDRESS=8000
export JPDA_TRANSPORT=dt_socket
and to start server in debug mode:
%TOMCAT_HOME%/bin/catalina.sh jpda start
Nah - I don't entirely agree with the rules. They are good guidelines to consider with performance and standardization, but not in light of the possibilities.
As you can see in the responses, there are a lot of creative ways to use them. So, these guidelines need to just be that, always for the sake of performance and efficiency.
In this case, I use classes to represent real world objects in their larger form, I use structs to represent smaller objects that have more exact uses. The way you said it, "a more cohesive whole." The keyword being cohesive. The classes will be more object oriented elements, while structs can have some of those characteristics, though on a smaller scale. IMO.
I use them a lot in Treeview and Listview tags where common static attributes can be accessed very quickly. I have always struggled to get this info another way. For example, in my database applications, I use a Treeview where I have Tables, SPs, Functions, or any other objects. I create and populate my struct, put it in the tag, pull it out, get the data of the selection and so forth. I wouldn't do this with a class!
I do try and keep them small, use them in single instance situations, and keep them from changing. It's prudent to be aware of memory, allocation, and performance. And testing is so necessary.
My need was to resize text in order to perfectly fit view bounds. Chase's solution only reduces text size, this one enlarges also the text if there is enough space.
To make all fast & precise i used a bisection method instead of an iterative while, as you can see in resizeText()
method. That's why you have also a MAX_TEXT_SIZE
option. I also included onoelle's tips.

There's no history in the database itself, if you're using psql you can use "\s" to see your command history there.
You can get future queries or other types of operations into the log files by setting log_statement in the postgresql.conf file. What you probably want instead is log_min_duration_statement, which if you set it to 0 will log all queries and their durations in the logs. That can be helpful once your apps goes live, if you set that to a higher value you'll only see the long running queries which can be helpful for optimization (you can run EXPLAIN ANALYZE on the queries you find there to figure out why they're slow).
Another handy thing to know in this area is that if you run psql and tell it "\timing", it will show how long every statement after that takes. So if you have a sql file that looks like this:
\timing
select 1;
You can run it with the right flags and see each statement interleaved with how long it took. Here's how and what the result looks like:
$ psql -ef test.sql
Timing is on.
select 1;
?column?
----------
1
(1 row)
Time: 1.196 ms
This is handy because you don't need to be database superuser to use it, unlike changing the config file, and it's easier to use if you're developing new code and want to test it out.
I think @Flo254 chained $salt
to $password1
and stored them to $hashed
variable. $hashed
variable goes inside INSERT
query with $salt
.
I used title and it worked!
The title attribute gives the title of the link. With one exception, it is purely advisory. The value is text. The exception is for style sheet links, where the title attribute defines alternative style sheet sets.

You could use my JavaScript hash table implementation, jshashtable. It allows any object to be used as a key, not just strings.
As an addendum to this, I've strings of the form: Some words 303
where I'd like to split off the numerical part from the tail of the string. This seems to point to a possible solution:
http://lists.mysql.com/mysql/222421
The problem however, is that you only get the answer "yes, it matches", and not the start index of the regexp match.
One more reason, maybe your url include some hiden characters, such as '\n'.
If you define your url like below, this exception will raise:
url = '''
http://google.com
'''
because there are '\n' hide in the string. The url in fact become:
\nhttp://google.com\n
Use this method to remove tags:
public string From_To(string text, string from, string to)
{
if (text == null)
return null;
string pattern = @"" + from + ".*?" + to;
Regex rx = new Regex(pattern, RegexOptions.Compiled | RegexOptions.IgnoreCase);
MatchCollection matches = rx.Matches(text);
return matches.Count <= 0 ? text : matches.Cast<Match>().Where(match => !string.IsNullOrEmpty(match.Value)).Aggregate(text, (current, match) => current.Replace(match.Value, ""));
}
I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.
If your XML is in a string variable called txt
and looks like this:
<address>
<street>Roble Ave</street>
<mtfcc>S1400</mtfcc>
<streetNumber>649</streetNumber>
<lat>37.45127</lat>
<lng>-122.18032</lng>
<distance>0.04</distance>
<postalcode>94025</postalcode>
<placename>Menlo Park</placename>
<adminCode2>081</adminCode2>
<adminName2>San Mateo</adminName2>
<adminCode1>CA</adminCode1>
<adminName1>California</adminName1>
<countryCode>US</countryCode>
</address>
Then you can parse the XML with Javascript DOM like this:
if (window.DOMParser)
{
parser = new DOMParser();
xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // Internet Explorer
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.loadXML(txt);
}
And get specific values from the nodes like this:
//Gets house address number
xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue;
//Gets Street name
xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue;
//Gets Postal Code
xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue;
In response to @gaugeinvariante's concerns about xml with Namespace prefixes. Should you have a need to parse xml with Namespace prefixes, everything should work almost identically:
NOTE: this will only work in browsers that support xml namespace prefixes such as Microsoft Edge
// XML with namespace prefixes 's', 'sn', and 'p' in a variable called txt_x000D_
txt = `_x000D_
<address xmlns:p='example.com/postal' xmlns:s='example.com/street' xmlns:sn='example.com/streetNum'>_x000D_
<s:street>Roble Ave</s:street>_x000D_
<sn:streetNumber>649</sn:streetNumber>_x000D_
<p:postalcode>94025</p:postalcode>_x000D_
</address>`;_x000D_
_x000D_
//Everything else the same_x000D_
if (window.DOMParser)_x000D_
{_x000D_
parser = new DOMParser();_x000D_
xmlDoc = parser.parseFromString(txt, "text/xml");_x000D_
}_x000D_
else // Internet Explorer_x000D_
{_x000D_
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");_x000D_
xmlDoc.async = false;_x000D_
xmlDoc.loadXML(txt);_x000D_
}_x000D_
_x000D_
//The prefix should not be included when you request the xml namespace_x000D_
//Gets "streetNumber" (note there is no prefix of "sn"_x000D_
console.log(xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Street name_x000D_
console.log(xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Postal Code_x000D_
console.log(xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue);

The official tutorial discusses deploying an app to production. One option is to use Waitress, a production WSGI server. Other servers include Gunicorn and uWSGI.
When running publicly rather than in development, you should not use the built-in development server (
flask run
). The development server is provided by Werkzeug for convenience, but is not designed to be particularly efficient, stable, or secure.Instead, use a production WSGI server. For example, to use Waitress, first install it in the virtual environment:
$ pip install waitress
You need to tell Waitress about your application, but it doesn’t use
FLASK_APP
like flask run does. You need to tell it to import and call the application factory to get an application object.$ waitress-serve --call 'flaskr:create_app' Serving on http://0.0.0.0:8080
Or you can use waitress.serve()
in the code instead of using the CLI command.
from flask import Flask
app = Flask(__name__)
@app.route("/")
def index():
return "<h1>Hello!</h1>"
if __name__ == "__main__":
from waitress import serve
serve(app, host="0.0.0.0", port=8080)
$ python hello.py
Do you have a typo in your .h? I once came across this error when i had the method properly called in my main, but with a typo in the .h/.cpp (a "g" vs a "q" in the method name, which made it kinda difficult to spot). It falls under the "copy/paste error" category.
I had the same issue and I have gone through all these solutions given, but none of them worked for me. But then I realised my stupid mistake. I forgot to change Code signing identity to iOS Distribution from iOS Developer, under build settings tab. Please make sure you have selected 'iOS Distribution' there.
Try this one
UPDATE employee
set EMPLOYEE.MAIDEN_NAME =
(SELECT ADD1
FROM EMPS
WHERE EMP_CODE=EMPLOYEE.EMP_CODE);
WHERE EMPLOYEE.EMP_CODE >='00'
AND EMPLOYEE.EMP_CODE <='ZZ';
Add a file called mongoHelper.js
var MongoClient = require('mongodb').MongoClient;
MongoClient.saveAny = function(data, collection, callback)
{
if(data instanceof Array)
{
saveRecords(data,collection, callback);
}
else
{
saveRecord(data,collection, callback);
}
}
function saveRecord(data, collection, callback)
{
collection.save
(
data,
{w:1},
function(err, result)
{
if(err)
throw new Error(err);
callback(result);
}
);
}
function saveRecords(data, collection, callback)
{
save
(
data,
collection,
callback
);
}
function save(data, collection, callback)
{
collection.save
(
data.pop(),
{w:1},
function(err, result)
{
if(err)
{
throw new Error(err);
}
if(data.length > 0)
save(data, collection, callback);
else
callback(result);
}
);
}
module.exports = MongoClient;
Then in your code change you requires to
var MongoClient = require("./mongoHelper.js");
Then when it is time to save call (after you have connected and retrieved the collection)
MongoClient.saveAny(data, collection, function(){db.close();});
You can change the error handling to suit your needs, pass back the error in the callback etc.
There is no way to retrieve localStorage, sessionStorage or cookie values via javascript in the browser after they've been deleted via javascript.
If what you're really asking is if there is some other way (from outside the browser) to recover that data, that's a different question and the answer will entirely depend upon the specific browser and how it implements the storage of each of those types of data.
For example, Firefox stores cookies as individual files. When a cookie is deleted, its file is deleted. That means that the cookie can no longer be accessed via the browser. But, we know that from outside the browser, using system tools, the contents of deleted files can sometimes be retrieved.
If you wanted to look into this further, you'd have to discover how each browser stores each data type on each platform of interest and then explore if that type of storage has any recovery strategy.
var data = [];
data = {{ jdata|safe }}; //parse through js
var i = 0 ;
for (i=0;i<data.length;i++){
data[i] = data[i].value;
}
The Clone() method returns a new array (a shallow copy) object containing all the elements in the original array. The CopyTo() method copies the elements into another existing array. Both perform a shallow copy. A shallow copy means the contents (each array element) contains references to the same object as the elements in the original array. A deep copy (which neither of these methods performs) would create a new instance of each element's object, resulting in a different, yet identical object.
So the difference are :
1- CopyTo require to have a destination array when Clone return a new array.
2- CopyTo let you specify an index (if required) to the destination array.
Edit:
Remove the wrong example.
you can set a width for yor element which will show only the button and will hide the "no file chosen".
whereever you want it to, if you set it your function call: error_log($errorMessageforLog . "\n", 4, 'somePath/SomeFileName.som');
We can also use space in a char class, in an expression similar to one of these:
(?!^[ ]*$)^\S+$
(?!^[ ]*$)^\S{1,}$
(?!^[ ]{0,}$)^\S{1,}$
(?!^[ ]{0,1}$)^\S{1,}$
depending on the language/flavor that we might use.
using System;
using System.Text.RegularExpressions;
public class Example
{
public static void Main()
{
string pattern = @"(?!^[ ]*$)^\S+$";
string input = @"
abcd
ABCD1234
#$%^&*()_+={}
abc def
ABC 123
";
RegexOptions options = RegexOptions.Multiline;
foreach (Match m in Regex.Matches(input, pattern, options))
{
Console.WriteLine("'{0}' found at index {1}.", m.Value, m.Index);
}
}
}
If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.
jex.im visualizes regular expressions:
Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)
import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1
u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0
#option 1
#keep index of t
u.index = t.index
#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)
#now concat will keep number of rows
r=pd.concat([t,u], axis=1)
round
does take negative ndigits
parameter!
>>> round(46,-1)
50
may solve your case.
While creating the user like 'myuser'@'localhost', the user gets limited to be connected only from localhost. Create a user only for remote access and use your remote client IP address from where you will be connecting to the MySQL server. If you can bear the risk of allowing connections from all remote hosts (usually when using dynamic IP address), you can use 'myuser'@'%'. I did this, and also removed bind_address from /etc/mysql/mysql.cnf (Ubuntu) and now it connects flawlessly.
mysql> select host,user from mysql.user;
+-----------+-----------+
| host | user |
+-----------+-----------+
| % | myuser |
| localhost | mysql.sys |
| localhost | root |
+-----------+-----------+

The correct answer is this (example version):
In parent pom.xml you should have (not inside properties
):
<version>0.0.1-SNAPSHOT</version>
In all child modules you should have:
<parent>
<groupId>com.vvirlan</groupId>
<artifactId>grafiti</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
So it is hardcoded.
Now, to update the version you do this:
mvn versions:set -DnewVersion=0.0.2-SNAPSHOT
mvn versions:commit # Necessary to remove the backup file pom.xml
and all your 400 modules will have the parent version updated.
