You can try adb remount command also to remount /system as read write
adb remount
You might need to run it via cmd
, eg:
system("cmd /c C:[path to file]");
Here is what I look at everytime I am writing a new crontab entry:
To start editing from terminal -type:
zee$ crontab -e
what you will add to crontab file:
0 22 * * 0 some-user /opt/somescript/to/run.sh
What it means:
[
+ user => 'some-user',
+ minute => ‘0’, <<= on top of the hour.
+ hour => '22', <<= at 10 PM. Military time.
+ monthday => '*', <<= Every day of the month*
+ month => '*', <<= Every month*
+ weekday => ‘0’, <<= Everyday (0 thru 6) = sunday thru saturday
]
Also, check what shell your machine is running and name the the file accordingly OR it wont execute.
Check the shell with either echo $SHELL
or echo $0
It can be "Bourne shell (sh)
, Bourne again shell (bash)
,Korn shell (ksh)
..etc"
You want the "popen" function. Here's an example of running the command "ls /etc" and outputing to the console.
#include <stdio.h>
#include <stdlib.h>
int main( int argc, char *argv[] )
{
FILE *fp;
char path[1035];
/* Open the command for reading. */
fp = popen("/bin/ls /etc/", "r");
if (fp == NULL) {
printf("Failed to run command\n" );
exit(1);
}
/* Read the output a line at a time - output it. */
while (fgets(path, sizeof(path), fp) != NULL) {
printf("%s", path);
}
/* close */
pclose(fp);
return 0;
}
For checking device version which is greater than or equal to Marshmallow ,use this code.
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M){
}
for ckecking others just change the VERSION_CODES like,
K for kitkat,
L for loolipop
N for Nougat and so on...
If you check out the subprocess section of the Python docs, you'll notice there is an example of how to replace os.system()
with subprocess.Popen()
:
sts = os.system("mycmd" + " myarg")
...does the same thing as...
sts = Popen("mycmd" + " myarg", shell=True).wait()
The "improved" code looks more complicated, but it's better because once you know subprocess.Popen()
, you don't need anything else. subprocess.Popen()
replaces several other tools (os.system()
is just one of those) that were scattered throughout three other Python modules.
If it helps, think of subprocess.Popen()
as a very flexible os.system()
.
I couldn't figure out why popen/pclose is missing from Code::Blocks/MinGW. So I worked around the problem by using CreateProcess() and CreatePipe() instead.

Recently I noticed the same issue in Android Studio 3.3. I closed the other Android studio projects and Logcat started working. The accepted answer above is not logical at all.
Use the collapse
argument to paste
:
paste(a,collapse=" ")
[1] "aa bb cc"
System.out.println(Integer.toHexString(test[0]));
OR (pretty print)
System.out.printf("0x%02X", test[0]);
OR (pretty print)
System.out.println(String.format("0x%02X", test[0]));
Code
import java.util.Scanner;
public class LoginMain {
public static void main(String[] args) {

String Password;
Password = "123";

Scanner input1 = new Scanner(System.in);
System.out.println("Enter Username : ");
String username = input1.next();

You can use system() or %x[] depending what kind of result you need.
system() returning true if the command was found and ran successfully, false otherwise.
>> s = system 'uptime'
10:56 up 3 days, 23:10, 2 users, load averages: 0.17 0.17 0.14
=> true
>> s.class
=> TrueClass
>> $?.class
=> Process::Status
%x[..] on the other hand saves the results of the command as a string:
>> result = %x[uptime]
=> "13:16 up 4 days, 1:30, 2 users, load averages: 0.39 0.29 0.23\n"
>> p result
"13:16 up 4 days, 1:30, 2 users, load averages: 0.39 0.29 0.23\n"
>> result.class
=> String
Th blog post by Jay Fields explains in detail the differences between using system, exec and %x[..] .
The system function requires const char *, and your expression is of the type std::string
. You should write
string name = "john";
string system_str = " quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'";
system(system_str.c_str ());
Using backtick
or qx
helps, thanks everybody for the answers. However, I found that if you use backtick
or qx
, the output contains trailing newline and I need to remove that. So I used chomp
.
chomp($host = `hostname`);
chomp($domain = `domainname`);
$fqdn = $host.".".$domain;
More information here: http://irouble.blogspot.in/2011/04/perl-chomp-backticks.html
I think the difference between the two boils down to access. Environment variables are accessible by any process and Java system properties are only accessible by the process they are added to.
Also as Bohemian stated, env variables are set in the OS (however they 'can' be set through Java) and system properties are passed as command line options or set via setProperty()
.
This aggregate all the goodies:
psutil
+ os
to get Unix & Windows compatibility:
That allows us to get:
code:
import os
import psutil # need: pip install psutil
In [32]: psutil.virtual_memory()

I think the best method out there is to implement the SIGAR API by Hyperic. It works for most of the major operating systems ( darn near anything modern ) and is very easy to work with. The developer(s) are very responsive on their forum and mailing lists. I also like that it is GPL2 Apache licensed. They provide a ton of examples in Java too!
edit: I just saw you meant in c#. Here is a better way with unmanaged code:
ManagementClass oMClass = new ManagementClass ("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection colMObj = oMCLass.GetInstances();
foreach(ManagementObject objMO in colMObj)
Console.WriteLine(objMO["MacAddress"].ToString());
We have two options.
Look at Preferences->Locations->"Custom Paths" in Xcode's preference. A path added here will be a variable which you can add to "Header Search Paths" in project build settings as "$cppheaders", if you saved the custom path with that name.
Set HEADER_SEARCH_PATHS
parameter in build settings on project info. I added "${SRCROOT}"
here without recursion. This setting works well for most projects.
About 2nd option:
Xcode uses Clang which has GCC compatible command set.
GCC has an option -Idir
which adds system header searching paths. And this option is accessible via HEADER_SEARCH_PATHS
in Xcode project build setting.
However, path string added to this setting should not contain any whitespace characters because the option will be passed to shell command as is.
But, some OS X users (like me) may put their projects on path including whitespace which should be escaped. You can escape it like /Users/my/work/a\ project\ with\ space
if you input it manually. You also can escape them with quotes to use environment variable like "${SRCROOT}"
.
Or just use .
to indicate current directory. I saw this trick on Webkit's source code, but I am not sure that current directory will be set to project directory when building it.
The ${SRCROOT}
is predefined value by Xcode. This means source directory. You can find more values in Reference document.
PS. Actually you don't have to use braces {}
. I get same result with $SRCROOT
. If you know the difference, please let me know.
Yes. The only way would be to drop the constraint with an Alter table then recreate it.
ALTER TABLE <Table_Name>
DROP CONSTRAINT <constraint_name>
ALTER TABLE <Table_Name>
ADD CONSTRAINT <constraint_name> PRIMARY KEY (<Column1>,<Column2>)
Regarding increasing the max stack size, on 32 bit and 64 bit machines V8's memory allocation defaults are, respectively, 700 MB and 1400 MB. In newer versions of V8, memory limits on 64 bit systems are no longer set by V8, theoretically indicating no limit. However, the OS (Operating System) on which Node is running can always limit the amount of memory V8 can take, so the true limit of any given process cannot be generally stated.
Though V8 makes available the --max_old_space_size
option, which allows control over the amount of memory available to a process, accepting a value in MB. Should you need to increase memory allocation, simply pass this option the desired value when spawning a Node process.
It is often an excellent strategy to reduce the available memory allocation for a given Node instance, especially when running many instances. As with stack limits, consider whether massive memory needs are better delegated to a dedicated storage layer, such as an in-memory database or similar.
Although the answer with "!" was chosen as the correct answer, this is NOT true. I´m not sure about Windows Explorer in Windows 10/8.1/8, but I am certain concerning Windows 7 and XP.
The character that moves your filename to the very top is "'" (alt+39), and second best is "-" (the minus sign).
But sorting order in Windows Explorer is more complicated - it depends on the filename-lenght also, and numbers are treated very special.
The second character (and the following) is treated different. Here you often go best with a " " (spacebar), followed by the characters mentioned above, but you´ll have to try out, because it´s not so easy to find out the exact algorithm:
Here is an example for the correct sorting order for your understanding:
Another example:
Same filelenght:
Finally the very special logic when it comes to numbers:
But nevertheless: Renaming folders or files this way, you can quickly find what you are searching for.
Whoever wants UML deserves Rational Rose :)
Quoting the Scheduling Repeating Alarms - Understand the Trade-offs docs:
A common scenario for triggering an operation outside the lifetime of your app is syncing data with a server. This is a case where you might be tempted to use a repeating alarm. But if you own the server that is hosting your app's data, using Google Cloud Messaging (GCM) in conjunction with sync adapter is a better solution than AlarmManager. A sync adapter gives you all the same scheduling options as AlarmManager, but it offers you significantly more flexibility.
So, based on this, the best way to schedule a server call is using Google Cloud Messaging (GCM) in conjunction with sync adapter.
Another alternative: you can check if an item is in a list with if item in list:
, but this is order O(n). If you are dealing with big lists of items and all you need to know is whether something is a member of your list, you can convert the list to a set first and take advantage of constant time set lookup:
my_set = set(my_list)
if item in my_set: # much faster on average than using a list
# do something
Not going to be the correct solution in every case, but for some cases this might give you better performance.
Note that creating the set with set(my_list)
is also O(n), so if you only need to do this once then it isn't any faster to do it this way. If you need to repeatedly check membership though, then this will be O(1) for every lookup after that initial set creation.
You're getting that error because the default value current_time
is not valid for the type DATETIME
. That's what it says, and that's whats going on.
The only field you can use current_time
on is a timestamp.
getcwd()

$_SERVER['SCRIPT_FILENAME']
If you are only looking to point to a different location for you identity file, the you can modify your ~/.ssh/config file with the following entry:
IdentityFile ~/.foo/identity
man ssh_config
to find other config options.
When posting an HTML checkbox to the server, it has a string value of 'on' or ''.
Readonly does not stop the user editing the checkbox, and disabled stops the value being posted back.
One way around this is to have a hidden element to store the actual value and the displayed checkbox is a dummy which is disabled. This way the checkbox state is persisted between posts.
Here is a function to do this. It uses a string of 'T' or 'F' and you can change this any way you like. This has been used in an ASP page using server side VB script.
public function MakeDummyReadonlyCheckbox(i_strName, i_strChecked_TorF)
dim strThisCheckedValue
if (i_strChecked_TorF = "T") then
strThisCheckedValue = " checked "
i_strChecked_TorF = "on"
else
strThisCheckedValue = ""
i_strChecked_TorF = ""
end if
MakeDummyReadonlyCheckbox = "<input type='hidden' id='" & i_strName & "' name='" & i_strName & "' " & _
"value='" & i_strChecked_TorF & "'>" & _
"<input type='checkbox' disabled id='" & i_strName & "Dummy' name='" & i_strName & "Dummy' " & _
strThisCheckedValue & ">"
end function
public function GetCheckbox(i_objCheckbox)
select case trim(i_objCheckbox)
case ""
GetCheckbox = "F"
case else
GetCheckbox = "T"
end select
end function
At the top of an ASP page you can pickup the persisted value...
strDataValue = GetCheckbox(Request.Form("chkTest"))
and when you want to output your checkbox you can do this...
response.write MakeDummyReadonlyCheckbox("chkTest", strDataValue)
I have tested this and it works just fine. It also does not rely upon JavaScript.
Since this is the first SO thread that seemed to come up for me when searching for "unresolved externals with static const members" in general, I'll leave another hint to solve one problem with unresolved externals here:
For me, the thing that I forgot was to mark my class definition __declspec(dllexport)
, and when called from another class (outside that class's dll's boundaries), I of course got the my unresolved external error.
Still, easy to forget when you're changing an internal helper class to a one accessible from elsewhere, so if you're working in a dynamically linked project, you might as well check that, too.
Modify the following rc parameters by adding the commands to the script:
plt.rcParams['xtick.bottom'] = False
plt.rcParams['xtick.labelbottom'] = False
A sample matplotlibrc file is depicted in this section of the matplotlib documentation, which lists many other parameters like changing figure size, color of figure, animation settings, etc.
If you want to load/process/display images I suggest you use an image processing framework. Using Marvin, for instance, you can do that easily with just a few lines of source code.
Source code:
public class Example extends JFrame{
MarvinImagePlugin prewitt = MarvinPluginLoader.loadImagePlugin("org.marvinproject.image.edge.prewitt");
MarvinImagePlugin errorDiffusion = MarvinPluginLoader.loadImagePlugin("org.marvinproject.image.halftone.errorDiffusion");
MarvinImagePlugin emboss = MarvinPluginLoader.loadImagePlugin("org.marvinproject.image.color.emboss");
public Example(){
super("Example");
// Layout
setLayout(new GridLayout(2,2));
// Load images
MarvinImage img1 = MarvinImageIO.loadImage("./res/car.jpg");
MarvinImage img2 = new MarvinImage(img1.getWidth(), img1.getHeight());
MarvinImage img3 = new MarvinImage(img1.getWidth(), img1.getHeight());
MarvinImage img4 = new MarvinImage(img1.getWidth(), img1.getHeight());
// Image Processing plug-ins
errorDiffusion.process(img1, img2);
prewitt.process(img1, img3);
emboss.process(img1, img4);
// Set panels
addPanel(img1);
addPanel(img2);
addPanel(img3);
addPanel(img4);
setSize(560,380);
setVisible(true);
}
public void addPanel(MarvinImage image){
MarvinImagePanel imagePanel = new MarvinImagePanel();
imagePanel.setImage(image);
add(imagePanel);
}
public static void main(String[] args) {
new Example().setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
Output:
If you don't want the weekends to appear at all, simply:
CSS
th.ui-datepicker-week-end,
td.ui-datepicker-week-end {
display: none;
}
In addition to all the other correct answers, since Rails.root
is a Pathname
object, this won't work:
Rails.root + '/app/assets/...'
You could use something like join
Rails.root.join('app', 'assets')
If you want a string use this:
Rails.root.join('app', 'assets').to_s
window.open didn't work for me... just a blank page rendered... but I was able to make the png appear on the page by replacing the src attribute of a pre-existing img element created as the target.
$("#btn_screenshot").click(function(){_x000D_
element_to_png("container", "testhtmltocanvasimg");_x000D_
});_x000D_
_x000D_
_x000D_
function element_to_png(srcElementID, targetIMGid){_x000D_
console.log("element_to_png called for element id " + srcElementID);_x000D_
html2canvas($("#"+srcElementID)[0]).then( function (canvas) {_x000D_
var myImage = canvas.toDataURL("image/png");_x000D_
$("#"+targetIMGid).attr("src", myImage);_x000D_
console.log("html2canvas completed. png rendered to " + targetIMGid);_x000D_
});_x000D_
}
_x000D_
<div id="testhtmltocanvasdiv" class="mt-3">_x000D_
<img src="" id="testhtmltocanvasimg">_x000D_
</div>
_x000D_
I can then right-click on the rendered png and "save as". May be just as easy to use the "snipping tool" to capture the element, but html2canvas is an certainly an interesting bit of code!
You can use getDimensionPixelOffset() instead of getDimension, so you didn't have to cast to int.
int valueInPixels = getResources().getDimensionPixelOffset(R.dimen.test)
The matrix you pasted
[[ 1, 8, 50],
[ 8, 64, 400],
[ 50, 400, 2500]]
Has a determinant of zero. This is the definition of a Singular matrix (one for which an inverse does not exist)
In the definition of your Card
class, a declaration for a default construction appears:
class Card
{
// ...
Card(); // <== Declaration of default constructor!
// ...
};
But no corresponding definition is given. In fact, this function definition (from card.cpp
):
void Card() {
//nothing
}
Does not define a constructor, but rather a global function called Card
that returns void
. You probably meant to write this instead:
Card::Card() {
//nothing
}
Unless you do that, since the default constructor is declared but not defined, the linker will produce error about undefined references when a call to the default constructor is found.
The same applies to your constructor accepting two arguments. This:
void Card(Card::Rank rank, Card::Suit suit) {
cardRank = rank;
cardSuit = suit;
}
Should be rewritten into this:
Card::Card(Card::Rank rank, Card::Suit suit) {
cardRank = rank;
cardSuit = suit;
}
And the same also applies for other member functions: it seems you did not add the Card::
qualifier before the member function names in their definitions. Without it, those functions are global functions rather than definitions of member functions.
Your destructor, on the other hand, is declared but never defined. Just provide a definition for it in card.cpp
:
Card::~Card() { }
SQL Server doesn't allow you to reference the alias in the GROUP BY clause because of the logical order of processing. The GROUP BY clause is processed before the SELECT clause, so the alias is not known when the GROUP BY clause is evaluated. This also explains why you can use the alias in the ORDER BY clause.
Here is one source for information on the SQL Server logical processing phases.
I actually disagree with SLaks. That solution did not work for me. Exception did not happen as expected. But this code worked for me:
if(System.IO.Directory.Exists(path))
{
...
}
It seems pretty consistent to me; positive indices are also non-inclusive. I think you're doing it wrong. Remembering that range() is also non-inclusive, and that Python arrays are 0-indexed, here's a sample python session to illustrate:
>>> d = range(10)
>>> d
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> d[9]
9
>>> d[-1]
9
>>> d[0:9]
[0, 1, 2, 3, 4, 5, 6, 7, 8]
>>> d[0:-1]
[0, 1, 2, 3, 4, 5, 6, 7, 8]
>>> len(d)

tabindex
is a global attribute responsible for two things:
In my mind the second thing is even more important than the first one. There are very few elements that are focusable by default (e.g. <a> and form controls). Developers very often add some JavaScript event handlers (like 'onclick') on not focusable elements (<div>, <span> and so on), and the way to make your interface be responsive not only to mouse events but also to keyboard events (e.g. 'onkeypress') is to make such elements focusable. Lastly, if you don't want to set the order but just make your element focusable use tabindex="0"
on all such elements:
<div tabindex="0"></div>
Also, if you don't want it to be focusable via the tab key then use tabindex="-1"
. For example, the below link will not be focused while using tab keys to traverse.
<a href="#" tabindex="-1">Tab key cannot reach here!</a>
For example you have a start program named run.sh to start it working at background do the following command line. ./run.sh &>/dev/null &
Open Outlook 2013 > File > Office account > About Outlook > click large "? About Outlook" button > read popup description
Besides the original answer, I have done the following:
this.setState({abc: {xyz: 'new value'}});
will NOT work, as state.abc
will be entirely overwritten, not merged.
This works for me:
this.setState((previousState) => {
previousState.abc.xyz = 'blurg';
return previousState;
});
Unless I'm reading the docs wrong, Facebook recommends the above format. https://facebook.github.io/react/docs/component-api.html
Additionally, I guess the most direct way without mutating state is to directly copy by using the ES6 spread/rest operator:
const newState = { ...this.state.abc }; // deconstruct state.abc into a new object-- effectively making a copy
newState.xyz = 'blurg';
this.setState(newState);

In Ruby 1.9.2 and above they added a .to_date function to DateTime:
http://ruby-doc.org/stdlib-1.9.2/libdoc/date/rdoc/DateTime.html#method-i-to_date
This instance method doesn't appear to be present in earlier versions like 1.8.7.
Strangely setting a transparent border solved this for me:
@media print {
div {
border: 1px solid rgba(0,0,0,0)
}
}
Maybe it will suffice to set the border on the container element. <- Untestet.
Check out my article Protect Your Java Code - Through Obfuscators And Beyond [Archived] for a discussion of obfuscation vs three other ways to make the reverse engineering of your apps more expensive, and a collection of links to tools and further reading materials.
As said Will Wagner, in old version of jsp you should always use c:out
to output dynamic text.
Moreover, using this syntax:
<c:out value="${person.name}">No name</c:out>
you can display the text "No name" when name is null.
If you want to show error messages on form submission, you can use condition form.$submitted
to check if an attempt was made to submit the form. Check following example.
<form name="myForm" novalidate ng-submit="myForm.$valid && createUser()">
<input type="text" name="name" ng-model="user.name" placeholder="Enter name of user" required>
<div ng-messages="myForm.name.$error" ng-if="myForm.$submitted">
<div ng-message="required">Please enter user name.</div>
</div>
<input type="text" name="address" ng-model="user.address" placeholder="Enter Address" required ng-maxlength="30">
<div ng-messages="myForm.name.$error" ng-if="myForm.$submitted">
<div ng-message="required">Please enter user address.</div>
<div ng-message="maxlength">Should be less than 30 chars</div>
</div>
<button type="submit">
Create user
</button>
</form>
SQL Server provides a built-in stored procedure that you can run to easily show the size of a table, including the size of the indexes… which might surprise you.
Syntax:
sp_spaceused 'Tablename'
see in :
http://www.howtogeek.com/howto/database/determine-size-of-a-table-in-sql-server/
Wrap it in a scroll viewer:
<ScrollViewer>
<TextBlock />
</ScrollViewer>
NOTE this answer applies to a TextBlock
(a read-only text element) as asked for in the original question.
If you want to show scroll bars in a TextBox
(an editable text element) then use the ScrollViewer
attached properties:
<TextBox ScrollViewer.HorizontalScrollBarVisibility="Disabled"
ScrollViewer.VerticalScrollBarVisibility="Auto" />
Valid values for these two properties are Disabled
, Auto
, Hidden
and Visible
.
var appBanners = document.getElementsByClassName('appBanner');
for (var i = 0; i < appBanners.length; i ++) {
appBanners[i].style.display = 'none';
}
A today extension would be the most fitting solution.
Also you could do something on the lock screen with local notifications queued up to fire at regular intervals showing the latest countdown value.
Yes this is possible
Since the question is update, this solution can only gives you the embed url not the HLS url, check @JAL answer.

Ok, SO Basically I think I have a simple and effective solution.
package AnotherPopUpMessage;
import javax.swing.JOptionPane;
public class AnotherPopUp {
public static void main(String[] args) {
// TODO Auto-generated method stub
JOptionPane.showMessageDialog(null, "Again? Where do all these come from?",
"PopUp4", JOptionPane.CLOSED_OPTION);
}
}
The solution is fairly straight forward. To ensure that we don't impact the width of the cells in the table, we'll turn off white-space. To ensure we get a horizontal scroll bar, we'll turn on overflow-x. And that's pretty much it:
.container {
width: 30em;
overflow-x: auto;
white-space: nowrap;
}
You can see the end-result here, or in the animation below. If the table determines the height of your container, you should not need to explicitly set overflow-y
to hidden
. But understand that is also an option.
As you stated in the comments, some of the values appeared to be floats, not strings. You will need to change it to strings before passing it to re.sub
. The simplest way is to change location
to str(location)
when using re.sub
. It wouldn't hurt to do it anyways even if it's already a str
.
letters_only = re.sub("[^a-zA-Z]", # Search for all non-letters
" ", # Replace all non-letters with spaces
str(location))
Here's one slight alteration to the answers of a query that creates the table upon execution (i.e. you don't have to create the table first):
SELECT * INTO #Temp
FROM (
select OptionNo, OptionName from Options where OptionActive = 1
) as X
partition by
doesn't actually roll up the data. It allows you to reset something on a per group basis. For example, you can get an ordinal column within a group by partitioning on the grouping field and using rownum()
over the rows within that group. This gives you something that behaves a bit like an identity column that resets at the beginning of each group.
I found the answer.
You can configure IE8 to display application/json in the browser window by updating the registry. There's no need for an external tool. I haven't tested this broadly, but it works with IE8 on Vista.
To use this, remember, all the usual caveats about updating the registry apply. Stop IE. Then, cut and paste the following into a file, by the name of json-ie.reg
.
Windows Registry Editor Version 5.00
;
; Tell IE to open JSON documents in the browser.
; 25336920-03F9-11cf-8FD0-00AA00686F13 is the CLSID for the "Browse in place" .
;
[HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/json]
"CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"
"Encoding"=hex:08,00,00,00
[HKEY_CLASSES_ROOT\MIME\Database\Content Type\text/json]
"CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"
"Encoding"=hex:08,00,00,00
Then double-click the .reg file. Restart IE. The new behavior you get when tickling a URL that returns a doc with Content-Type: application/json
or Content-Type: text/json
is like this:
What it does, why it works:
The 25336920-03F9-11cf-8FD0-00AA00686F13
is the CLSID for the "Browse in place" action. Basically this registry entry is telling IE that for docs that have a mime type of application/json, just view it in place. This won't affect any application/json documents downloaded via <script>
tags, or via XHR, and so on.
The CLSID and Encoding keys get the same values used for image/gif
, image/jpeg
, and text/html
.
This hint came from this site, and from Microsoft's article Handling MIME Types in Internet Explorer .
In FF, you don't need an external add-on either. You can just use the view-source:
pseudo-protocol. Enter a URL like this into the address bar:
view-source:http://myserver/MyUrl/That/emits/Application/json
This pseudo-protocol used to be supported in IE, also, until WinXP-sp2, when Microsoft disabled it for security reasons.
As documented in ?legend
you do this like so:
plot(1:10,type = "n")
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",box.lwd = 0,box.col = "white",bg = "white")
points(1:10,1:10)
Line breaks are achieved with the new line character \n
. Making the points still visible is done simply by changing the order of plotting. Remember that plotting in R is like drawing on a piece of paper: each thing you plot will be placed on top of whatever's currently there.
Note that the legend text is cut off because I made the plot dimensions smaller (windows.options does not exist on all R platforms).
You simply call
Blog::all();
//example usage.
$posts = Blog::all();
$posts->each(function($post) // foreach($posts as $post) { }
{
//do something
}
from anywhere in your application.
Reading the documentation will help a lot.
Simple.
Assuming that in your Activity-1
, you did this:
String stringExtra = "Some string you want to pass";
Intent intent = new Intent(this, AndroidTabRestaurantDescSearchListView.class);
//include the string in your intent
intent.putExtra("string", stringExtra);
startActivity(intent);
And in your AndroidTabRestaurantDescSearchListView class, do this:
//fetch the string from the intent
String extraFromAct1 = getIntent().getStringExtra("string");
Intent intent = new Intent(this, RatingDescriptionSearchActivity.class);
//attach same string and send it with the intent
intent.putExtra("string", extraFromAct1);
startActivity(intent);
Then in your RatingDescriptionSearchActivity class, do this:
String extraFromAct1 = getIntent().getStringExtra("string");
@vj9 thx. I update to xcode 7 . It show me the same error. Build well after set "NO"
set "NO" it works well.
I had a similar issue - very slow xml downloads followed by an empty package list. The SDK, it seems, was trying to use legacy Java installation. Setting the JAVA_HOME to the 1.6 jdk did the trick.
I wouldn't recommend this, but if you're really into it being one line and only writing 0 once, you can also do this:
int row, column, index = row = column = 0;
Code:
str = "http://localhost/with spaces and spaces"
encoded = URI::encode(str)
puts encoded
Result:
http://localhost/with%20spaces%20and%20spaces
use wget
module of python instead. Here is a snippet
import wget
wget.download(url)
If it's a sorted array you could use a Binary search algorithm (O(log n)
). For example, extending the Array-class with this functionality:
class Array
def b_search(e, l = 0, u = length - 1)
return if lower_index > upper_index
midpoint_index = (lower_index + upper_index) / 2
return midpoint_index if self[midpoint_index] == value
if value < self[midpoint_index]
b_search(value, lower_index, upper_index - 1)
else
b_search(value, lower_index + 1, upper_index)
end
end
end
Your code seems to be fine, make sure that key you specify really exists in the array or such key has a value in your array eg:
$array = array(4 => 'Hello There');
print_r(array_keys($array));
// or better
print_r($array);
Output:
Array
(
[0] => 4
)
Now:
$key = 4;
$value = $array[$key];
print $value;
Output:
Hello There
Try to see if the following code helps you:

Here is a plunker showing how you can use it with the ngClass
directive.
I'm demonstrating with div
s instead of img
s though.
Template:
<ul>
<li><div [ngClass]="{'this-is-a-class': selectedIndex == 1}" (click)="setSelected(1)"> </div></li>
<li><div [ngClass]="{'this-is-a-class': selectedIndex == 2}" (click)="setSelected(2)"> </div></li>
<li><div [ngClass]="{'this-is-a-class': selectedIndex == 3}" (click)="setSelected(3)"> </div></li>
</ul>
TS:
export class App {
selectedIndex = -1;
setSelected(id: number) {
this.selectedIndex = id;
}
}
The case is like :
mysql connects will localhost when network is not up.
mysql cannot connect when network is up.
You can try the following steps to diagnose and resolve the issue (my guess is that some other service is blocking port on which mysql is hosted):
This should ideally resolve the issue you are facing.
df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))
df
## b c d
## 1 1 2 3
## 2 1 2 3
## 3 1 2 3
df <- data.frame(a = c(0, 0, 0), df)
df
## a b c d
## 1 0 1 2 3
## 2 0 1 2 3
## 3 0 1 2 3
You could use the or
operator:
return x or "default"
Note that this also returns "default"
if x
is any falsy value, including an empty list, 0, empty string, or even datetime.time(0)
(midnight).
Dictionary does not define order of items. If you just need an item use Keys
or Values
properties of dictionary to pick one.
Here is a method using a lookup table of thresholds and associated colours to map the colours to the variable of interest.
# make a grid 'Grd' of points and number points for side of square 'GrdD'
Grd <- expand.grid(seq(0.5,400.5,10),seq(0.5,400.5,10))
GrdD <- length(unique(Grd$Var1))
# Add z-values to the grid points
Grd$z <- rnorm(length(Grd$Var1), mean = 10, sd =2)
# Make a vector of thresholds 'Brks' to colour code z
Brks <- c(seq(0,18,3),Inf)
# Make a vector of labels 'Lbls' for the colour threhsolds
Lbls <- Lbls <- c('0-3','3-6','6-9','9-12','12-15','15-18','>18')
# Make a vector of colours 'Clrs' for to match each range
Clrs <- c("grey50","dodgerblue","forestgreen","orange","red","purple","magenta")
# Make up lookup dataframe 'LkUp' of the lables and colours
LkUp <- data.frame(cbind(Lbls,Clrs),stringsAsFactors = FALSE)
# Add a new variable 'Lbls' the grid dataframe mapping the labels based on z-value
Grd$Lbls <- as.character(cut(Grd$z, breaks = Brks, labels = Lbls))
# Add a new variable 'Clrs' to the grid dataframe based on the Lbls field in the grid and lookup table
Grd <- merge(Grd,LkUp, by.x = 'Lbls')
# Plot the grid using the 'Clrs' field for the colour of each point
plot(Grd$Var1,
Grd$Var2,
xlim = c(0,400),
ylim = c(0,400),
cex = 1.0,
col = Grd$Clrs,
pch = 20,
xlab = 'mX',
ylab = 'mY',
main = 'My Grid',
axes = FALSE,
labels = FALSE,
las = 1
)
axis(1,seq(0,400,100))
axis(2,seq(0,400,100),las = 1)
box(col = 'black')
legend("topleft", legend = Lbls, fill = Clrs, title = 'Z')
SQLServer 2008 now has a 'date' data type which contains only a date with no time component. Anyone using SQLServer 2008 and beyond can do the following:
SELECT CONVERT(date, GETDATE())
I don't think all the other answerers understood the question correctly. The question requires disabling editing part of the text. One solution I can think of is simulating a textbox with a fixed prefix which is not part of the textarea or input.
An example of this approach is:
<div style="border:1px solid gray; color:#999999; font-family:arial; font-size:10pt; width:200px; white-space:nowrap;">Default Notes<br/>
<textarea style="border:0px solid black;" cols="39" rows="5"></textarea></div>
The other approach, which I end up using is using JS and JQuery to simulate "Disable" feature. Example with pseudo-code (cannot be specific cause of legal issue):
// disable existing notes by preventing keystroke
document.getElementById("txtNotes").addEventListener('keydown', function (e) {
if (cursorLocation < defaultNoteLength ) {
e.preventDefault();
});
// disable existing notes by preventing right click
document.addEventListener('contextmenu', function (e) {
if (cursorLocation < defaultNoteLength )
e.preventDefault();
});
Thanks, Carsten, for mentioning that this question is old, but I found that the solution might help other people in the future.
In case if you want to implement your own Array.Copy method.
Static method which is of generic type.
static void MyCopy<T>(T[] sourceArray, long sourceIndex, T[] destinationArray, long destinationIndex, long copyNoOfElements)
{
long totaltraversal = sourceIndex + copyNoOfElements;
long sourceArrayLength = sourceArray.Length;
//to check all array's length and its indices properties before copying
CheckBoundaries(sourceArray, sourceIndex, destinationArray, copyNoOfElements, sourceArrayLength);
for (long i = sourceIndex; i < totaltraversal; i++)
{
destinationArray[destinationIndex++] = sourceArray[i];
}
}
Boundary method implementation.
private static void CheckBoundaries<T>(T[] sourceArray, long sourceIndex, T[] destinationArray, long copyNoOfElements, long sourceArrayLength)
{
if (sourceIndex >= sourceArray.Length)
{
throw new IndexOutOfRangeException();
}
if (copyNoOfElements > sourceArrayLength)

throw new IndexOutOfRangeException();

if (destinationArray.Length < copyNoOfElements)

You might have some luck calling the Win32 API's MessageBoxA, although whether Win16 supports that particular method is for someone else to answer.
Just wanted to drop a note. I was having trouble formatting a text 4000 field that had a mind of its own and the text would seeming wrap (or not wrap) randomly on the report. When I updated the column using the replace chr(10) noted above. My report finally formatted as I wanted. Many Thanx!
Elasticsearch settings are in $ES_HOME/config/elasticsearch.yml
. There, if the cluster.name
setting is commented out, it means ES would take just about any cluster name. So, in your code, the cluster.name
as "elastictest"
might be the problem. Try this:
Client client = new TransportClient()
.addTransportAddress(new InetSocketTransportAddress(
"143.79.236.xxx",
9300));
The method jQuery (v1.10) uses to find this is:
var doc = document.documentElement;
var left = (window.pageXOffset || doc.scrollLeft) - (doc.clientLeft || 0);
var top = (window.pageYOffset || doc.scrollTop) - (doc.clientTop || 0);
That is:
window.pageXOffset
first and uses that if it exists.document.documentElement.scrollLeft
.document.documentElement.clientLeft
if it exists.The subtraction of document.documentElement.clientLeft
/ Top
only appears to be required to correct for situations where you have applied a border (not padding or margin, but actual border) to the root element, and at that, possibly only in certain browsers.
I used @Robin answer & listing all that I did,
git status <-- review/list uncommitted changes
git stash <-- stash uncommitted changes
git stash branch <new-branch> stash@{1} <-- create a branch from stash
git add . <-- add local changes
git status <-- review the status; ready to commit
git commit -m "local changes ..." <-- commit the changes
git branch --list <-- see list of branches incl the one created above
git status <-- nothing to commit, working tree (new-branch) is clean
git checkout <old-branch> <-- switch back
! If the repo has more than one stash, see which one to apply to the new-branch:
git stash list
stash@{0}: WIP on ...
stash@{1}: WIP on ...
and inspect the individual stash by,
git stash show stash@{1}
Or inspect all stashes at once:
git stash list -p
Here you go:
^[^<>]*$
This will test for string that has no <
and no >
If you want to test for a string that may have <
and >
, but must also have something other you should use just
[^<>] (or ^.*[^<>].*$)
Where [<>]
means any of <
or >
and [^<>]
means any that is not of <
or >
.
And of course the mandatory link.
Use case/esac
to test:
case "$var" in
"") echo "zero length";;

public static T Runner<T>(Func<T> funcToRun)

In code, you need to explicitly create a Brush
instance:
Fill = new SolidColorBrush(Color.FromArgb(0xff, 0xff, 0x90))
If you're in Rails, .blank?
should be the method you are looking for:
a = nil
b = []
c = ""
a.blank? #=> true
b.blank? #=> true
c.blank? #=> true
d = "1"
e = ["1"]
d.blank? #=> false
e.blank? #=> false
So the answer would be:
variable = id if variable.blank?
Or patch your kernel and remove the check.
(Option of last resort, not recommended).
In net/ipv4/af_inet.c
, remove the two lines that read
if (snum && snum < PROT_SOCK && !capable(CAP_NET_BIND_SERVICE))
goto out;
and the kernel won't check privileged ports anymore.

Resurrecting this question because the regex in the accepted answer doesn't seem quite correct to me. Why? Because
(?<=This is)(.*)(?=sentence)
will match my first sentence. This is my second
in This is my first sentence. This is my second sentence.
You need a lazy quantifier between the two lookarounds. Adding a ?
makes the star lazy.
This matches what you want:
(?<=This is).*?(?=sentence)
See demo. I removed the capture group, which was not needed.
DOTALL Mode to Match Across Line Breaks
Note that in the demo the "dot matches line breaks mode" (a.k.a.) dot-all is set (see how to turn on DOTALL in various languages). In many regex flavors, you can set it with the online modifier (?s)
, turning the expression into:
(?s)(?<=This is).*?(?=sentence)

create table my_table (
column_a integer not null,

Other answers seem a bit complex, you can just add a parameter 'label' in scatter function and that will be the legend for your plot.
import matplotlib.pyplot as plt
from numpy.random import random
colors = ['b', 'c', 'y', 'm', 'r']
lo = plt.scatter(random(10), random(10), marker='x', color=colors[0],label='Low Outlier')
ll = plt.scatter(random(10), random(10), marker='o', color=colors[0],label='LoLo')
l = plt.scatter(random(10), random(10), marker='o', color=colors[1],label='Lo')
a = plt.scatter(random(10), random(10), marker='o', color=colors[2],label='Average')
h = plt.scatter(random(10), random(10), marker='o', color=colors[3],label='Hi')
hh = plt.scatter(random(10), random(10), marker='o', color=colors[4],label='HiHi')
ho = plt.scatter(random(10), random(10), marker='x', color=colors[4],label='High Outlier')
plt.legend(loc='upper center', bbox_to_anchor=(0.5, -0.05),
fancybox=True, shadow=True, ncol=4)

Source: Use NATURAL FULL JOIN to compare two tables in SQL by Lukas Eder
Clever approach of using NATURAL FULL JOIN
to detect the same/different rows between two tables.
Example 1 - status flag:
SELECT t1.*, t2.*, CASE WHEN t1 IS NULL OR t2 IS NULL THEN 'Not equal' ELSE 'Equal' END
FROM t1
NATURAL FULL JOIN t2;
Example 2 - filtering rows
SELECT *
FROM (SELECT 't1' AS t1, t1.* FROM t1) t1
NATURAL FULL JOIN (SELECT 't2' AS t2, t2.* FROM t2) t2
WHERE t1 IS NULL OR t2 IS NULL -- show differences
--WHERE t1 IS NOT NULL AND t2 IS NOT NULL -- show the same
And this is the Factory implementation, as Jon Skeet suggested:
interface Factory<T> {
T factory();
}
class Araba {
//static inner class for Factory<T> implementation
public static class ArabaFactory implements Factory<Araba> {
public Araba factory() {
return new Araba();
}
}
public String toString() { return "Abubeee"; }
}
class Generic<T> {
private T var;
Generic(Factory<T> fact) {
System.out.println("Constructor with Factory<T> parameter");
var = fact.factory();
}
Generic(T var) {
System.out.println("Constructor with T parameter");
this.var = var;
}
T get() { return var; }
}
public class Main {
public static void main(String[] string) {
Generic<Araba> gen = new Generic<Araba>(new Araba.ArabaFactory());
System.out.print(gen.get());
}
}
Output:
Constructor with Factory<T> parameter
Abubeee
I think it is linked with your RAM (or probably virtual memory) space and for the absolute maximum constrained to your OS version (e.g. 32 bit or 64 bit)
This is caused by the regional settings of your computer.
When you paste data into excel it is only a bunch of strings (not dates).
Excel has some logic in it to recognize your current data formats as well as a few similar date formats or obvious date formats where it can assume it is a date. When it is able to match your pasted in data to a valid date then it will format it as a date in the cell it is in.
Your specific example is due to your list of dates is formatted as "m/d/yy" which is US format. it pastes correctly in my excel because I have my regional setting set to "US English" (even though I'm Canadian :) )
If you system is set to Canadian English/French format then it will expect "d/m/yy" format and not recognize any date where the month is > 13.
The best way to import data, that contains dates, into excel is to copy it in this format.
2011-04-22
2011-12-19
2011-11-04
2011-12-08
2011-09-27
2011-09-27
2011-04-01
Which is "yyyy-MM-dd", this format is recognized the same way on every computer I have ever seen (is often refered to as ODBC format or Standard format) where the units are always from greatest to least weight ("yyyy-MM-dd HH:mm:ss.fff") another side effect is it will sort correctly as a string.
To avoid swaping your regional settings back and forth you may consider writting a macro in excel to paste the data in. a simple popup format and some basic logic to reformat the dates would not be too difficult.
The best way to install the Zip extension in php7.2 on CentOS would be as below:
Find the available extention by searching with yum command
yum search zip
This will list all the zip packages. We need to look for the php7.2 zip package
Then if your php version is 7.2 then run the command
yum install ea-php72-php-zip
This will definetly resolve your issue.
Cheers !!
This works for me and you don't need the inline script:
Javascript:
$(document).ready(function() {
$('.showme').bind('click', function() {
var id=$(this).attr("id");
var num=$(this).attr("class");
var poststr="request="+num+"&moreinfo="+id;
$.ajax({
url:"testme.php",
cache:0,
data:poststr,
success:function(result){
document.getElementById("stuff").innerHTML=result;
}
});
});
});
HTML:
<div class='request_1 showme' id='rating_1'>More stuff 1</div>
<div class='request_2 showme' id='rating_2'>More stuff 2</div>
<div class='request_3 showme' id='rating_3'>More stuff 3</div>
<div id="stuff">Here is some stuff that will update when the links above are clicked</div>
The request is sent to testme.php:
header("Cache-Control: no-cache");
header("Pragma: nocache");
$request_id = preg_replace("/[^0-9]/","",$_REQUEST['request']);
$request_moreinfo = preg_replace("/[^0-9]/","",$_REQUEST['moreinfo']);
if($request_id=="1")
{
echo "show 1";
}
elseif($request_id=="2")
{
echo "show 2";
}
else
{
echo "show 3";
}
In urls.py
you can override the 3 most important variables:
from django.contrib import admin
admin.site.site_header = 'My project' # default: "Django Administration"
admin.site.index_title = 'Features area' # default: "Site administration"
admin.site.site_title = 'HTML title from adminsitration' # default: "Django site admin"
Reference: Django documentation on these attributes.
List<String> result = Arrays.asList("abc".split(""));
I suggest Use Webview If you want to move short strings horizontally. Main_Activity.java Code:`
WebView webView;
webView = (WebView)findViewById(R.id.web);
String summary = "<html><FONT color='#fdb728' FACE='courier'><marquee behavior='scroll' direction='left' scrollamount=10>"
+ "Hello Droid" + "</marquee></FONT></html>";
webView.loadData(summary, "text/html", "utf-8"); // Set focus to the textview
`
main_activity.xml code:
<WebView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/web"
></WebView>
How about:
writing-mode:tb-rl
Where top->bottom, right->left?
We will need vertical rule for this.
Use arrows or hjkl
to get to one of the bracketing expressions, then v
to select visual (i.e. selecting) mode, then %
to jump to the other bracket.
If someone is looking for another option for Git Lab and the options above do not work, then we have another option. For a local installation of Git Lab server, we have found that the approach, below, allows us to include the package dependency. We generated and use an access token to do so.
$ npm install --save-dev https://git.yourdomain.com/userOrGroup/gitLabProjectName/repository/archive.tar.gz?private_token=InsertYourAccessTokenHere
Of course, if one is using an access key this way, it should have a limited set of permissions.
Good luck!
This is kind of a specific case, but in case anyone gets here with my problem:
In MongoHQ, it'll show you a field called "password", but it's actually just the hash of the password. You'll have to add a new user and store the password elsewhere (because MongoHQ won't show it to you).
Maybe these steps are not quite correct, but I do like this:
stop docker compose: $ docker-compose down
remove the container: $ docker system prune -a
start docker compose: $ docker-compose up -d
cd to sessions directory and then:
1) View sessions older than 40 min:
find . -amin +40 -exec stat -c "%n %y" {} \;
2) Remove sessions older than 40 min:
find . -amin +40 -exec rm {} \;
x(end+1) = newElem
is a bit more robust.
x = [x newElem]
will only work if x
is a row-vector, if it is a column vector x = [x; newElem]
should be used. x(end+1) = newElem
, however, works for both row- and column-vectors.
In general though, growing vectors should be avoided. If you do this a lot, it might bring your code down to a crawl. Think about it: growing an array involves allocating new space, copying everything over, adding the new element, and cleaning up the old mess...Quite a waste of time if you knew the correct size beforehand :)
The -i
flag specifies the private key (.pem file) to use. If you don't specify that flag (as in your first command) it will use your default ssh key (usually under ~/.ssh/
).
So in your first command, you are actually asking scp
to upload the .pem file itself using your default ssh key. I don't think that is what you want.
Try instead with:
scp -r -i /Applications/XAMPP/htdocs/keypairfile.pem uploads/* ec2-user@publicdns:/var/www/html/uploads
You can use the following regular expression which will match integers (e.g., 123
), floating-point numbers (12.3
), and numbers with exponents (1.2e3
):
^-?\d*\.?\d+([eE]-?\d+)?$
If you want to accept +
signs as well as -
signs (as Oracle does with TO_NUMBER()
), you can change each occurrence of -
above to [+-]
. So you might rewrite your block of code above as follows:
IF (option_id = 0021) THEN
IF NOT REGEXP_LIKE(value, '^[+-]?\d*\.?\d+([eE][+-]?\d+)?$') OR TO_NUMBER(value) < 10000 OR TO_NUMBER(value) > 7200000 THEN
ip_msg(6214,option_name);
RETURN;
END IF;
END IF;
I am not altogether certain that would handle all values so you may want to add an EXCEPTION
block or write a custom to_number()
function as @JustinCave suggests.
Well, you can use xpath utility. I guess perl's XML::Xpath contains it.
Here is an simple example:
$("#country_id").change(function(){
if(this.value.toString() == ""){
return;
}
alert("You just changed country to: " + $("#country_id option:selected").text() + " which carried the value for country_id as: " + this.value.toString());
});
As others have said, mysql does not provide regex tools for extracting sub-strings. That's not to say you can't have them though if you're prepared to extend mysql with user-defined functions:
https://github.com/mysqludf/lib_mysqludf_preg
That may not be much help if you want to distribute your software, being an impediment to installing your software, but for an in-house solution it may be appropriate.
#include <algorithm>
#include <string>
using namespace std;
string f( __FILE__ );
f = string( (find(f.rbegin(), f.rend(), '/')+1).base() + 1, f.end() );
// searches for the '/' from the back, transfers the reverse iterator
// into a forward iterator and constructs a new sting with both
double degree = fmodf((atan2(x, y) * (180.0 / M_PI)) + 360, 360);
This will return degree from 0°-360° counter-clockwise, 0° is at 3 o'clock.
Inline functions have special rules about what extern
means. (Note that inline functions are a C99 or GNU extension; they weren't in original C.
For non-inline functions, extern
is not needed as it is on by default.
Note that the rules for C++ are different. For example, extern "C"
is needed on the C++ declaration of C functions that you are going to call from C++, and there are different rules about inline
.
form.onsubmit will always be a function when defined as an attribute of HTML the form element. It's some sort of anonymous function attached to an HTML element, which has the this pointer bound to that FORM element and also has a parameter named event
which will contain data about the submit event.
Under these circumstances I don't understand how you got a string as a result of a typeof operation. You should give more details, better some code.
Edit (as a response to your second edit):
I believe the handler attached to the HTML attribute will execute regardless of the above code. Further more, you could try to stop it somehow, but, it appears that FF 3, IE 8, Chrome 2 and Opera 9 are executing the HTML attribute handler in the first place and then the one attached (I didn't tested with jQuery though, but with addEventListener and attachEvent). So... what are you trying to accomplish exactly?
By the way, your code isn't working because your regular expression will extract the string "valid();", which is definitely not a function.
Yes, use the jQuery contains
selector.
The question is When do you use map vs flatMap in RxJava?. And I think a simple demo is more specific.
When you want to convert item emitted to another type , in your case converting file to String, map and flatMap can both work. But I prefer map operator because it's more clearly.
However in some place, flatMap
can do magic work but map
can't. For example, I want to get a user's info but I have to first get his id when user login in. Obviously I need two requests and they are in order.
Let's begin.
Observable<LoginResponse> login(String email, String password);
Observable<UserInfo> fetchUserInfo(String userId);
Here are two methods, one for login returned Response
, and another for fetching user info.
login(email, password)
.flatMap(response ->
fetchUserInfo(response.id))
.subscribe(userInfo -> {
// get user info and you update ui now
});
As you see, in function flatMap applies, at first I get user id from Response
then fetch user info. When two requests are finished, we can do our job such as updating UI or save data into database.
However if you use map
you can't write such nice code. In a word, flatMap
can help us serialize requests.
Since List<> uses arrays internally, the basic performance should be the same. Two reasons, why the List might be slightly slower:
To check if it makes any difference for you, it's probably best adjust the posted timing functions to a list of the size you're planning to use and see how the results for your special case are.

range for A-Z but if you want to go for example from A to DU then:
function generateAlphabet($na) {
$sa = "";
while ($na >= 0) {
$sa = chr($na % 26 + 65) . $sa;
$na = floor($na / 26) - 1;
}
return $sa;
}
$alphabet = Array();
for ($na = 0; $na < 125; $na++) {
$alphabet[]=generateAlphabet($na);

Rendering happens after change detection. To force change detection, so that component property values that have changed get propagated to the DOM (and then the browser will render those changes in the view), here are some options:
$rootScope.$digest()
-- i.e., check the full component tree$rootScope.$apply(callback)
-- i.e., evaluate the callback function inside the Angular 2 zone. I think, but I'm not sure, that this ends up checking the full component tree after executing the callback function.$scope.$digest()
-- i.e., check only this component and its childrenYou will need to import and then inject ApplicationRef
, NgZone
, or ChangeDetectorRef
into your component.
For your particular scenario, I would recommend the last option if only a single component has changed.
you can change the file executable by using chmod
like this
chmod 755 file.sh

I ran into this issue with the Oracle 11R2 client. Not sure if the Oracle installer did this or someone did it here before i arrived. It was not 64-bit vs 32-bit, all was 64-bit.
The error was that libexpat.so.1
was not a symbolic link.
It turned out that there were two identical files, libexpat.so.1.5.2
and libexpat.so.1
. Removing the offending file and making it a symlink to the 1.5.2 version caused the error to go away.
Makes sense that you'd want the well-known name to be a symlink to the current version. If you do this, it's less likely that you'll end up with a stale library.
just type "git push" if this doesn't give you a positive replay, then check if you are connected with your repository correctly.
On unix systems, you can use the following command to determine where git is installed:

If you are using MacOS and did a recent update, it is possible you have to agree to the licence terms again. Try typing 'git' in a terminal, and see if you get the following message:
Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.
I had similar situation where late subscribers subscribe to the Subject after its value arrived.
I found ReplaySubject which is similar to BehaviorSubject works like a charm in this case. And here is a link to better explanation: http://reactivex.io/rxjs/manual/overview.html#replaysubject
From outside the defining class, as @Telos mentions, you can only use EventHandler on the left-hand side of a +=
or a -=
. So, if you have the ability to modify the defining class, you could provide a method to perform the check by checking if the event handler is null
- if so, then no event handler has been added. If not, then maybe and you can loop through the values in
Delegate.GetInvocationList. If one is equal to the delegate that you want to add as event handler, then you know it's there.
public bool IsEventHandlerRegistered(Delegate prospectiveHandler)
{
if ( this.EventHandler != null )
{
foreach ( Delegate existingHandler in this.EventHandler.GetInvocationList() )
{
if ( existingHandler == prospectiveHandler )
{
return true;
}
}
}
return false;
}
And this could easily be modified to become "add the handler if it's not there". If you don't have access to the innards of the class that's exposing the event, you may need to explore -=
and +=
, as suggested by @Lou Franco.
However, you may be better off reexamining the way you're commissioning and decommissioning these objects, to see if you can't find a way to track this information yourself.

You can customize Facebook share dialog box by using asynchronous JavaScript SDK provided by Facebook and setting up its parameter values
Have a look at the following code:
<script type="text/javascript">
$(document).ready(function(){
$('#share_button').click(function(e){
e.preventDefault();
FB.ui(
{
method: 'feed',
name: 'This is the content of the "name" field.',
link: 'URL which you would like to share ',
picture: ‘URL of the image which is going to appear as thumbnail image in share dialogbox’,
caption: 'Caption like which appear as title of the dialog box',
description: 'Small description of the post',
message: ''
}
);
});
});
</script>
Before copying and pasting the below code you must first initialize the SDK and set up jQuery library. Please click here to know a step by step how to set information on the same.
For context, I created a project using the ASP.NET Core 2 Web Application template. Then, select the Web Application (MVC) then hit the Change Authentication button and select Individual User accounts.
There is a lot of infrastructure built up for you from this template. Find the ManageController
in the Controllers folder.
This ManageController
class constructor requires this UserManager variable to populated:
private readonly UserManager<ApplicationUser> _userManager;
Then, take a look at the the [HttpPost] Index method in this class. They get the current user in this fashion:
var user = await _userManager.GetUserAsync(User);
As a bonus note, this is where you want to update any custom fields to the user Profile you've added to the AspNetUsers table. Add the fields to the view, then submit those values to the IndexViewModel which is then submitted to this Post method. I added this code after the default logic to set the email address and phone number:
user.FirstName = model.FirstName;
user.LastName = model.LastName;
user.Address1 = model.Address1;
user.Address2 = model.Address2;
user.City = model.City;
user.State = model.State;
user.Zip = model.Zip;
user.Company = model.Company;
user.Country = model.Country;
user.SetDisplayName();
user.SetProfileID();
_dbContext.Attach(user).State = EntityState.Modified;
_dbContext.SaveChanges();
First, be sure to read and understand the "How to write Go code" document.
The actual answer depends on the nature of your "custom package".
If it's intended to be of general use, consider employing the so-called "Github code layout". Basically, you make your library a separate go get
-table project.
If your library is for internal use, you could go like this:
To demonstrate:
src/
myproject/
mylib/
mylib.go
...
main.go
Now, in the top-level main.go
, you could import "myproject/mylib"
and it would work OK.
DISTINCT
is always a right choice to get unique values. Also you can do it alternatively without using it. That's GROUP BY
. Which has simply add at the end of the query and followed by the column name.
SELECT * FROM buy GROUP BY date,description
It is so simple clearfix clears the issue by when we using the float properties inside the div element.If we use two div elements one as float:left; and other one as float:right; we can use clearfix for the parent of the two div element. If we refuse to use clearfix unnecessary spaces fill with contents below and site structure will be broken.
From http://php.net/manual/en/function.serialize.php :
Generates a storable representation of a value. This is useful for storing or passing PHP values around without losing their type and structure.
Essentially, it takes a php array or object and converts it to a string (which you can then transmit or store as you see fit).
Unserialize is used to convert the string back to an object.
C99 does, if you have
#include <stdbool.h>
If the compiler does not support C99, you can define it yourself:
// file : myboolean.h
#ifndef MYBOOLEAN_H
#define MYBOOLEAN_H
#define false 0
#define true 1
typedef int bool; // or #define bool int
#endif
(but note that this definition changes ABI for bool
type so linking against external libraries which were compiled with properly defined bool
may cause hard-to-diagnose runtime errors).
Here is some supplemental literature on keepalive which explains it in much finer detail.
http://www.tldp.org/HOWTO/html_single/TCP-Keepalive-HOWTO
Since Java does not allow you to control the actual keepalive times, you can use the examples to change them if you're using a Linux kernel (or proc based OS).
>>> l = [list(range(i, i+4)) for i in range(10,1,-1)]
>>> l
[[10, 11, 12, 13], [9, 10, 11, 12], [8, 9, 10, 11], [7, 8, 9, 10], [6, 7, 8, 9], [5, 6, 7, 8], [4, 5, 6, 7], [3, 4, 5, 6], [2, 3, 4, 5]]
>>> sorted(l, key=sum)
[[2, 3, 4, 5], [3, 4, 5, 6], [4, 5, 6, 7], [5, 6, 7, 8], [6, 7, 8, 9], [7, 8, 9, 10], [8, 9, 10, 11], [9, 10, 11, 12], [10, 11, 12, 13]]
The above works. Are you doing something different?
Notice that your key function is just sum
; there's no need to write it explicitly.

I followed the steps in killthrush's answer and to my surprise it did not work. Logging in as sa I could see my Windows domain user and had made them a sysadmin, but when I tried logging in with Windows auth I couldn't see my login under logins, couldn't create databases, etc. Then it hit me. That login was probably tied to another domain account with the same name (with some sort of internal/hidden ID that wasn't right). I had left this organization a while back and then came back months later. Instead of re-activating my old account (which they might have deleted) they created a new account with the same domain\username and a new internal ID. Using sa I deleted my old login, re-added it with the same name and added sysadmin. I logged back in with Windows Auth and everything looks as it should. I can now see my logins (and others) and can do whatever I need to do as a sysadmin using my Windows auth login.
I've been searching for a workaround for this for a bit - and the only thing I have found is to use URL rewrites to read the "anchor". I found in the apache docs here http://httpd.apache.org/docs/2.2/rewrite/advanced.html the following...
By default, redirecting to an HTML anchor doesn't work, because mod_rewrite escapes the # character, turning it into %23. This, in turn, breaks the redirection.
Solution: Use the [NE] flag on the RewriteRule. NE stands for No Escape.
Discussion: This technique will of course also work with other special characters that mod_rewrite, by default, URL-encodes.
It may have other caveats and what not ... but I think that at least doing something with the # on the server is possible.
Keep in mind that tables in relational databases are just sets of rows. And sets in mathematics are unordered collections. There is no first or last row; no previous row or next row.
You'll have to sort your set of unordered rows by some field first, and then you are free the iterate through the resultset in the order you defined.
Since you have an auto incrementing field, I assume you want that to be the sorting field. In that case, you may want to do the following:
SELECT *
FROM your_table
ORDER BY your_auto_increment_field DESC
LIMIT 1;
See how we're first sorting the set of unordered rows by the your_auto_increment_field
(or whatever you have it called) in descending order. Then we limit the resultset to just the first row with LIMIT 1
.
I resolved this by deleting the contents of the bin and obj folders for the project, and the contents of the bin folder on the remote server, then redeploying.
If you want to add a product into the array you can use:
$item['product'] = $product;
I tried all of the above, however, still getting the same error message.
In my case an actual JRE was incorrectly used as JRE System Library in the project-specific build path which was obviously overriding all those other settings discussed here.
If that is so in your case try the following:
The grid system in Bootstrap 3 requires a bit of a lateral shift in your thinking from Bootstrap 2. A column in BS2 (col-*
) is NOT synonymous with a column in BS3 (col-sm-*
, etc), but there is a way to achieve the same result.
Check out this update to your fiddle: http://jsfiddle.net/pjBzY/22/ (code copied below).
First of all, you don't need to specify a col for each screen size if you want 50/50 columns at all sizes. col-sm-6
applies not only to small screens, but also medium and large, meaning class="col-sm-6 col-md-6"
is redundant (the benefit comes in if you want to change the column widths at different size screens, such as col-sm-6 col-md-8
).
As for the margins issue, the negative margins provide a way to align blocks of text in a more flexible way than was possible in BS2. You'll notice in the jsfiddle, the text in the first column aligns visually with the text in the paragraph outside the row
-- except at "xs" window sizes, where the columns aren't applied.
If you need behavior closer to what you had in BS2, where there is padding between each column and there are no visual negative margins, you will need to add an inner-div to each column. See the inner-content
in my jsfiddle. Put something like this in each column, and they will behave the way old col-*
elements did in BS2.
jsfiddle HTML
<div class="container">
<p class="other-content">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse aliquam sed sem nec viverra. Phasellus fringilla metus vitae libero posuere mattis. Integer sit amet tincidunt felis. Maecenas et pharetra leo. Etiam venenatis purus et nibh laoreet blandit.</p>
<div class="row">
<div class="col-sm-6 my-column">
Col 1
<p class="inner-content">Inner content - THIS element is more synonymous with a Bootstrap 2 col-*.</p>
</div>
<div class="col-sm-6 my-column">
Col 2
</div>
</div>
</div>
and the CSS
.row {
border: blue 1px solid;
}
.my-column {
background-color: green;
padding-top: 10px;
padding-bottom: 10px;
}
.my-column:first-child {
background-color: red;
}
.inner-content {
background: #eee;
border: #999;
border-radius: 5px;
padding: 15px;
}
When you are dealing with objects, you want to ignore simple id's as much as convenient.
If you change the click line to this, I think you will be well on your way:
<li class="tutorial_title {{tutorial.active}}" ng-click="loadFromMenu(tutorial)" ng-repeat="tutorial in section.tutorials">
Also, I think you may need to change
class="tutorial_title {{tutorial.active}}"
to something like
ng-class="tutorial_title {{tutorial.active}}"
See http://docs.angularjs.org/misc/faq and look for ng-class.

If I'm not mistaken, the default bean name of a bean declared with @Component is the name of its class its first letter in lower-case. This means that
@Component
public class SuggestionService {
declares a bean of type SuggestionService
, and of name suggestionService
. It's equivalent to
@Component("suggestionService")
public class SuggestionService {
or to
<bean id="suggestionService" .../>
You're redefining another bean of the same type, but with a different name, in the XML:
<bean id="SuggestionService" class="com.hp.it.km.search.web.suggestion.SuggestionService">
...
</bean>
So, either specify the name of the bean in the annotation to be SuggestionService
, or use the ID suggestionService
in the XML (don't forget to also modify the <ref>
element, or to remove it, since it isn't needed). In this case, the XML definition will override the annotation definition.
There are 3 possibilities on the MS KB

Updated, in Java 8:
Math.toIntExact(value);
Original Answer:
Simple type casting should do it:
long l = 100000;
int i = (int) l;
Note, however, that large numbers (usually larger than 2147483647
and smaller than -2147483648
) will lose some of the bits and would be represented incorrectly.
For instance, 2147483648
would be represented as -2147483648
.
I've done something like this;
var certificationClass = _db.INDIVIDUALLICENSEs
.Join(_db.INDLICENSECLAsses,
IL => IL.LICENSE_CLASS,
ILC => ILC.NAME,
(IL, ILC) => new { INDIVIDUALLICENSE = IL, INDLICENSECLAsse = ILC })
.Where(o =>
o.INDIVIDUALLICENSE.GLOBALENTITYID == "ABC" &&
o.INDIVIDUALLICENSE.LICENSE_TYPE == "ABC")
.Select(t => new
{
value = t.PSP_INDLICENSECLAsse.ID,
name = t.PSP_INDIVIDUALLICENSE.LICENSE_CLASS,
})
.OrderBy(x => x.name);
An example based on Chuck's answer:
myIntToStr :: Int -> String
myIntToStr x
| x < 3 = show x ++ " is less than three"
| otherwise = "normal"
Note that without the show
the third line will not compile.
ArrayDeque
are faster in the stack than a Stack or LinkedList. "push()" inserts elements at the front of the Deque
protected <T> Stream<T> reverse(Stream<T> stream) {
ArrayDeque<T> stack = new ArrayDeque<>();
stream.forEach(stack::push);
return stack.stream();
}
There are two ways to look at it:
Inline functions are defined in the header because, in order to inline a function call, the compiler must be able to see the function body. For a naive compiler to do that, the function body must be in the same translation unit as the call. (A modern compiler can optimize across translation units, and so a function call may be inlined even though the function definition is in a separate translation unit, but these optimizations are expensive, aren't always enabled, and weren't always supported by the compiler)
functions defined in the header must be marked inline
because otherwise, every translation unit which includes the header will contain a definition of the function, and the linker will complain about multiple definitions (a violation of the One Definition Rule). The inline
keyword suppresses this, allowing multiple translation units to contain (identical) definitions.
The two explanations really boil down to the fact that the inline
keyword doesn't exactly do what you'd expect.
A C++ compiler is free to apply the inlining optimization (replace a function call with the body of the called function, saving the call overhead) any time it likes, as long as it doesn't alter the observable behavior of the program.
The inline
keyword makes it easier for the compiler to apply this optimization, by allowing the function definition to be visible in multiple translation units, but using the keyword doesn't mean the compiler has to inline the function, and not using the keyword doesn't forbid the compiler from inlining the function.
I am new to Angular but have found this to solve my issue:
<i class="icon-download" ng-click="showDetails = ! showDetails" ng-class="{'icon-upload': showDetails}"></i>
This will conditionally apply a class based on a var.
It starts off with a icon-download as a default, the using ng-class, I check the status of showDetails
if true/false
and apply class icon-upload. Its working great.
Hope it helps.
You can use the HTMLParser module.
The code would probably look something like this:
from HTMLParser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_starttag(self, tag, attrs):
# Only parse the 'anchor' tag.
if tag == "a":
# Check the list of defined attributes.
for name, value in attrs:
# If href is defined, print it.
if name == "href":
print name, "=", value
parser = MyHTMLParser()
parser.feed(your_html_string)
Note: The HTMLParser module has been renamed to html.parser in Python 3.0. The 2to3 tool will automatically adapt imports when converting your sources to 3.0.
You could try to extract columns as list, massage this as you want, and reindex your dataframe:
>>> cols = df.columns.tolist()
>>> cols = [cols[-1]]+cols[:-1] # or whatever change you need
>>> df.reindex(columns=cols)
n l v
0 0 a 1
1 0 b 2
2 0 c 1
3 0 d 2
EDIT: this can be done in one line ; however, this looks a bit ugly. Maybe some cleaner proposal may come...
>>> df.reindex(columns=['n']+df.columns[:-1].tolist())
n l v
0 0 a 1
1 0 b 2
2 0 c 1
3 0 d 2
Put this on an event
$(function(){
$('.package').click(function(){
var content = $('.container').html();
$(this).html(content);
});
});
if you are looking to generate all the number within a specific rang randomly then you can try
r = randi([a b],1,d)
a
= start point
b
= end point
d
= how many number you want to generate but keep in mind that d should be less than or equal to b-a
You don't mention if it has to be batch only, but if you can use ROBOCOPY
, try this:
ROBOCOPY C:\Source C:\Destination data.zip info.txt /E
EDIT: Changed the /S
parameter to /E
to include empty folders.
I have been using this method for a while:
using System;
public static class ExtensionMethods {
// returns the number of milliseconds since Jan 1, 1970 (useful for converting C# dates to JS dates)
public static double UnixTicks(this DateTime dt)
{
DateTime d1 = new DateTime(1970, 1, 1);
DateTime d2 = dt.ToUniversalTime();
TimeSpan ts = new TimeSpan(d2.Ticks - d1.Ticks);
return ts.TotalMilliseconds;
}
}
Assuming you are developing against .NET 3.5, it's a straight copy/paste. You can otherwise port it.
You can encapsulate this in a JSON object, or simply write it to the response stream.
On the Javascript/JSON side, you convert this to a date by simply passing the ticks into a new Date object:
jQuery.ajax({
...
success: function(msg) {
var d = new Date(msg);
}
}
Everything in Java is passed by value. In case of an array (which is nothing but an Object), the array reference is passed by value (just like an object reference is passed by value).
When you pass an array to other method, actually the reference to that array is copied.
See this post: Is Java "pass-by-reference" or "pass-by-value"?
See this working example:
public static void changeContent(int[] arr) {
// If we change the content of arr.
arr[0] = 10; // Will change the content of array in main()
}
public static void changeRef(int[] arr) {
// If we change the reference
arr = new int[2]; // Will not change the array in main()
arr[0] = 15;
}
public static void main(String[] args) {
int [] arr = new int[2];
arr[0] = 4;
arr[1] = 5;
changeContent(arr);
System.out.println(arr[0]); // Will print 10..
changeRef(arr);
System.out.println(arr[0]); // Will still print 10..
// Change the reference doesn't reflect change here..
}
Install it by running
python setup.py install
Better yet, you can download from github. Install git via apt-get install git
and then follow this steps:
git clone https://github.com/mwaskom/seaborn.git
cd seaborn
python setup.py install
This is my Python function:
def add_nulls(num, cnt=2):
cnt = cnt - len(str(num))
nulls = '0' * cnt
return '%s%s' % (nulls, num)
You should include <string.h>
(or its C++ equivalent, <cstring>
).
Apache
, as usual, has a good answer from Apache Commons-Lang
in the form of
NumberUtils.isCreatable(String)
.

block required.
I wanted to use JavaScript to change a form's action, so I could have different submit inputs within the same form linking to different pages.
I also had the added complication of using Apache rewrite to change example.com/page-name
into example.com/index.pl?page=page-name
. I found that changing the form's action caused example.com/index.pl
(with no page parameter) to be rendered, even though the expected URL (example.com/page-name
) was displayed in the address bar.
To get around this, I used JavaScript to insert a hidden field to set the page parameter. I still changed the form's action, just so the address bar displayed the correct URL.
function setAction (element, page)
{
if(checkCondition(page))
{
/* Insert a hidden input into the form to set the page as a parameter.
*/
var input = document.createElement("input");
input.setAttribute("type","hidden");
input.setAttribute("name","page");
input.setAttribute("value",page);
element.form.appendChild(input);
/* Change the form's action. This doesn't chage which page is displayed,
* it just make the URL look right.
*/
element.form.action = '/' + page;
element.form.submit();
}
}
In the form:
<input type="submit" onclick='setAction(this,"my-page")' value="Click Me!" />
Here are my Apache rewrite rules:
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteRule ^/(.*)$ %{DOCUMENT_ROOT}/index.pl?page=$1&%{QUERY_STRING}
I'd be interested in any explanation as to why just setting the action didn't work.
Not mentioned in any answer but useful is the case where you want that option to be also selected, you can add:
var o = new Option("option text", "value");
o.selected=true;
$("#mySelect").append(o);
You can use DateFormat
(java.text.*) to parse the date:
DateFormat df = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy", Locale.ENGLISH);
Date d = df.parse("Mon May 27 11:46:15 IST 2013")
You will have to change the locale to match your own (with this you will get 10:46:15). Then you can use the same code you have to convert it to a timestamp.
Because a label element is not loaded when a script is executed. Swap the label and script elements, and it will work:
<label id="lbltipAddedComment"></label>
<script>
document.getElementById('lbltipAddedComment').innerHTML = 'Your tip has been submitted!';
</script>
add the line to your .bashrc
or .profile
. The variables set in $HOME/.profile
are active for the current user, the ones in /etc/profile
are global. The .bashrc

Had similar problem due to some CSV files that had various names for the same column.
This was the solution:
I wrote a function to return the first valid column name in a list, then used that...
# Return the string name of the first name in names that is a column name in tbl
# else null
ChooseCorrectColumnName <- function(tbl, names) {
for(n in names) {
if (n %in% colnames(tbl)) {
return(n)
}
}
return(null)
}
then...
cptcodefieldname = ChooseCorrectColumnName(file, c("CPT", "CPT.Code"))
icdcodefieldname = ChooseCorrectColumnName(file, c("ICD.10.CM.Code", "ICD10.Code"))
if (is.null(cptcodefieldname) || is.null(icdcodefieldname)) {
print("Bad file column name")
}
# Here we use the hash table implementation where
# we have a string key and list value so we need actual strings,
# not Factors
file[cptcodefieldname] = as.character(file[cptcodefieldname])
file[icdcodefieldname] = as.character(file[icdcodefieldname])
for (i in 1:length(file[cptcodefieldname])) {
cpt_valid_icds[file[cptcodefieldname][i]] <<- unique(c(cpt_valid_icds[[file[cptcodefieldname][i]]], file[icdcodefieldname][i]))
}
You can use input text with "list" attribute, which refers to the datalist of values.
<input type="text" name="city" list="cityname">_x000D_
<datalist id="cityname">_x000D_
<option value="Boston">_x000D_
<option value="Cambridge">_x000D_
</datalist>
_x000D_
This creates a free text input field that also has a drop-down to select predefined choices. Attribution for example and more information: https://www.w3.org/wiki/HTML/Elements/datalist
What you need to do is use the onchange
event listener in the form and change the href
attribute of the send button according to the context of the mail:

One of my concerns with phpMyAdmin was that by default, all MySQL users can access the db. If DB's root password is compromised, someone can wreck havoc on the db. I wanted to find a way to avoid that by restricting which MySQL user can login to phpMyAdmin.
I have found using AllowDeny configuration in PhpMyAdmin to be very useful. http://wiki.phpmyadmin.net/pma/Config#AllowDeny_.28rules.29
AllowDeny lets you configure access to phpMyAdmin in a similar way to Apache. If you set the 'order' to explicit, it will only grant access to users defined in 'rules' section. In the rules, section you restrict MySql users who can access use the phpMyAdmin.
$cfg['Servers'][$i]['AllowDeny']['order'] = 'explicit'
$cfg['Servers'][$i]['AllowDeny']['rules'] = array('pma-user from all')
Now you have limited access to the user named pma-user in MySQL, you can grant limited privilege to that user.
grant select on db_name.some_table to 'pma-user'@'app-server'
With lodash, in addition to the answer provided above, you can also have the key in the output array.
for:
const array = _.values(obj);
If obj is the following:
{ “art”: { id: 1, title: “aaaa” }, “fiction”: { id: 22, title: “7777”} }
Then array will be:
[ { id: 1, title: “aaaa” }, { id: 22, title: “7777” } ]
If you write instead ('genre' is a string that you choose):
const array= _.map(obj, (val, id) => {
return { ...val, genre: key };
});
You will get:
[
{ id: 1, title: “aaaa” , genre: “art”},
{ id: 22, title: “7777”, genre: “fiction” }
]

The issue was in fact that one of the properties was a relation to another table. I changed my LINQ query so that it could get the same data from a different method without needing to load the entire table.
Thank you all for your help!
In our case we experienced this while performing a load test on our app server. The issue turned out that we need to add additional memory to our JVM because it was running out. This resolved the issue.
Try increasing the memory available to the JVM and or monitor the memory usage when you get those errors.
Carry Flag is a flag set when:
a) two unsigned numbers were added and the result is larger than "capacity" of register where it is saved. Ex: we wanna add two 8 bit numbers and save result in 8 bit register. In your example: 255 + 9 = 264 which is more that 8 bit register can store. So the value "8" will be saved there (264 & 255 = 8) and CF flag will be set.
b) two unsigned numbers were subtracted and we subtracted the bigger one from the smaller one. Ex: 1-2 will give you 255 in result and CF flag will be set.
Auxiliary Flag is used as CF but when working with BCD. So AF will be set when we have overflow or underflow on in BCD calculations. For example: considering 8 bit ALU unit, Auxiliary flag is set when there is carry from 3rd bit to 4th bit i.e. carry from lower nibble to higher nibble. (Wiki link)
Overflow Flag is used as CF but when we work on signed numbers. Ex we wanna add two 8 bit signed numbers: 127 + 2. the result is 129 but it is too much for 8bit signed number, so OF will be set. Similar when the result is too small like -128 - 1 = -129 which is out of scope for 8 bit signed numbers.
You can read more about flags on wikipedia
You can find your sample code completely here: http://www.java2s.com/Code/Java/Hibernate/OneToManyMappingbasedonSet.htm
Have a look and check the differences. specially the even_id in :
<set name="attendees" cascade="all">
<key column="event_id"/>
<one-to-many class="Attendee"/>
</set>
This solution works well for me, on Develop and also on TEST and PROD servers with ASP.NET MVC5 via C#:
var projectDir = Path.GetDirectoryName(AppDomain.CurrentDomain.BaseDirectory);
If you need project directory in project configuration file use:
$(ProjectDir)
You can do it with plain JavaScript:
alert('123-4-'.substr(0, 4)); // outputs "123-"
This returns the first four characters of your string (adjust 4
to suit your needs).
Here is the syntax using jQuery $.get
$.get(url, data, successCallback, datatype)
So in your case, that would equate to,
var url = 'ajax.asp';
var data = { ajaxid: 4, UserID: UserID, EmailAddress: EmailAddress };
var datatype = 'jsonp';
function success(response) {
// do something here
}
$.get('ajax.aspx', data, success, datatype)
Note
$.get
does not give you the opportunity to set an error handler. But there are several ways to do it either using $.ajaxSetup(), $.ajaxError() or chaining a .fail
on your $.get
like below
$.get(url, data, success, datatype)
.fail(function(){
})
The reason for setting the datatype as 'jsonp' is due to browser same origin policy issues, but if you are making the request on the same domain where your javascript is hosted, you should be fine with datatype set to json
.
If you don't want to use the jquery $.get
then see the docs for $.ajax
which allows room for more flexibility
Follow @reVerse answer but in my case, I already had some property in my AppTheme
like
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
...
<item name="android:textColor">#111</item>
<item name="android:textSize">13sp</item>
</style>
I solved it by
1) Change the import from android.app.AlertDialog
to
android.support.v7.app.AlertDialog
2) I override 2 property in AppTheme
with null value
<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<!-- Used for the buttons -->
<item name="colorAccent">#FFC107</item>
<!-- Used for the title and text -->
<item name="android:textColorPrimary">#FFFFFF</item>
<!-- Used for the background -->
<item name="android:background">#4CAF50</item>
<item name="android:textColor">@null</item>
<item name="android:textSize">@null</item>
</style>
.
AlertDialog.Builder builder = new AlertDialog.Builder(mContext, R.style.MyAlertDialogStyle);
Hope it help another people
If I am not mistaken, it will be onunload event.
"Occurs when the application is about to be unloaded." - MSDN
As the Python interpreter reads the definition of a function (or, I think, even a block of indented code), all variables that are assigned to inside the function are added to the locals for that function. If a local does not have a definition before an assignment, the Python interpreter does not know what to do, so it throws this error.
The solution here is to add
global feed
to your function (usually near the top) to indicate to the interpreter that the feed variable is not local to this function.
Here is a simple way without stragg or creating a function.
create table countries ( country_name varchar2 (100));
insert into countries values ('Albania');
insert into countries values ('Andorra');
insert into countries values ('Antigua');
SELECT SUBSTR (SYS_CONNECT_BY_PATH (country_name , ','), 2) csv
FROM (SELECT country_name , ROW_NUMBER () OVER (ORDER BY country_name ) rn,
COUNT (*) OVER () cnt
FROM countries)
WHERE rn = cnt
START WITH rn = 1
CONNECT BY rn = PRIOR rn + 1;
CSV
--------------------------
Albania,Andorra,Antigua
1 row selected.
As others have mentioned, if you are on 11g R2 or greater, you can now use listagg which is much simpler.
select listagg(country_name,', ') within group(order by country_name) csv
from countries;
CSV
--------------------------
Albania, Andorra, Antigua
1 row selected.
You can do it with Alacon - command-line utility for Alasql database.
It works with Node.js, so you need to install Node.js and then Alasql package:
To calculate sum from stdin you can use the following command:
> cat data.txt | node alacon "SELECT VALUE SUM([0]) FROM TXT()" >b.txt
How about doing it like this:
1) show popup with form
2) submit form using AJAX
3) in AJAX server side code, render response that will either:
Try @Cacheable
from jcabi-aspects. With a single annotation you make the entire method result cacheable in memory:
public class Resource {
@Cacheable(lifetime = 5, unit = TimeUnit.SECONDS)
public String load(URL url) {
return url.openConnection().getContent();
}
}
Also, read this article: http://www.yegor256.com/2014/08/03/cacheable-java-annotation.html
Dart Object
type has a runtimeType
instance member (source is from dart-sdk
v1.14, don't know if it was available earlier)
class Object {
//...
external Type get runtimeType;
}
Usage:
Object o = 'foo';
assert(o.runtimeType == String);
As long as these are only "<" and ">" (and not the double quote itself) characters and you're using them in context like <input value="this" />, you're safe (while for <textarea>this one</textarea> you would be vulnerable of course). That may simplify your situation, but for anything more use one of other posted solutions.
If all above solutions is not working and In case of your project was working fine and now getting this issue, then try this,
try this following snippet, its working fine.

Observation : When you call static method within a static entity, you need to change the class in @PrepareForTest.
For e.g. :
securityAlgo = MessageDigest.getInstance(SECURITY_ALGORITHM);
For the above code if you need to mock MessageDigest class, use
@PrepareForTest(MessageDigest.class)
While if you have something like below :
public class CustomObjectRule {
object = DatatypeConverter.printHexBinary(MessageDigest.getInstance(SECURITY_ALGORITHM)
.digest(message.getBytes(ENCODING)));
}
then, you'd need to prepare the class this code resides in.
@PrepareForTest(CustomObjectRule.class)
And then mock the method :
PowerMockito.mockStatic(MessageDigest.class);
PowerMockito.when(MessageDigest.getInstance(Mockito.anyString()))
.thenThrow(new RuntimeException());
Mongoose's findById
method casts the id
parameter to the type of the model's _id
field so that it can properly query for the matching doc. This is an ObjectId but "foo"
is not a valid ObjectId so the cast fails.
This doesn't happen with 41224d776a326fb40f000001
because that string is a valid ObjectId.
One way to resolve this is to add a check prior to your findById
call to see if id
is a valid ObjectId or not like so:
if (id.match(/^[0-9a-fA-F]{24}$/)) {
// Yes, it's a valid ObjectId, proceed with `findById` call.
}
The safest way is to put the files you want kept to yourself outside of the web root directory, like Damien suggested. This works because the web server follows local file system privileges, not its own privileges.
However, there are a lot of hosting companies that only give you access to the web root. To still prevent HTTP requests to the files, put them into a directory by themselves with a .htaccess file that blocks all communication. For example,
Order deny,allow
Deny from all
Your web server, and therefore your server side language, will still be able to read them because the directory's local permissions allow the web server to read and execute the files.
Via Jquery:
$(location).attr('href','http://example.com/Registration/Success/');
Make the function take one parameter: an array. Pass in the actual parameters as values in the array.
Edit: the link in Pekka's comment just about sums it up.
In javascript you have to use \. to match a dot.
Example
"blah.tests.zibri.org".match('test\\..*')
null
and
"blah.test.zibri.org".match('test\\..*')
["test.zibri.org", index: 5, input: "blah.test.zibri.org", groups: undefined]
Named tuples were added in 2.6 for this purpose. Also see os.stat for a similar builtin example.
>>> import collections
>>> Point = collections.namedtuple('Point', ['x', 'y'])
>>> p = Point(1, y=2)
>>> p.x, p.y
1 2
>>> p[0], p[1]
1 2
In recent versions of Python 3 (3.6+, I think), the new typing
library got the NamedTuple
class to make named tuples easier to create and more powerful. Inheriting from typing.NamedTuple
lets you use docstrings, default values, and type annotations.
Example (From the docs):
class Employee(NamedTuple): # inherit from typing.NamedTuple
name: str
id: int = 3 # default value
employee = Employee('Guido')
assert employee.id == 3
