From How do I install a Python package with a .whl file? [sic], How do I install a Python package USING a .whl file ?
For all Windows platforms:
1) Download the .WHL package install file.
2) Make Sure path [C:\Progra~1\Python27\Scripts] is in the system PATH string. This is for using both [pip.exe] and [easy-install.exe].
3) Make sure the latest version of pip.EXE is now installed. At this time of posting:
pip.EXE --version
pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)
4) Run pip.EXE in an Admin command shell.
- Open an Admin privileged command shell.
> easy_install.EXE --upgrade pip
- Check the pip.EXE version:
> pip.EXE --version
pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)
> pip.EXE install --use-wheel --no-index
--find-links="X:\path to wheel file\DownloadedWheelFile.whl"
Be sure to double-quote paths or path\filenames with embedded spaces in them ! Alternatively, use the MSW 'short' paths and filenames.
This doesn't answer your question directly, but you can solve your problem with a one-liner:
find /tmp \( -name "*.pdf" -o -name "*.doc" \) -type f -exec rm {} +
Some versions of find (GNU, BSD) have a -delete
action which you can use instead of calling rm
:
find /tmp \( -name "*.pdf" -o -name "*.doc" \) -type f -delete
Assuming container is only on page once and you are using jQuery, then:
var containerEl = $('.container')[0];
var scrollbarWidth = containerEl.offsetWidth - containerEl.clientWidth;

if you want to check csv file is empty or not .......try this
with open('file.csv','a',newline='') as f:
csv_writer=DictWriter(f,fieldnames=['user_name','user_age','user_email','user_gender','user_type','user_check'])
if os.stat('file.csv').st_size > 0:
pass
else:
csv_writer.writeheader()
I know this is old but I just ran into this problem and none of the answers are suitable. nickf's solution works but it requires javascript. The best way is to disable the field and still pass the value is to use a hidden input field to pass the value to the form. For example,
<input type="text" value="22.2222" disabled="disabled" />
<input type="hidden" name="lat" value="22.2222" />
This way the value is passed but the user sees the greyed out field. The readonly attribute does not gray it out.
You find source (Scala) here and an working applet here.
Since 0 and 1 aren't matched to characters, they build natural breakpoints in numbers. But they don't occur in every number (except 0 at the beginning). Longer numbers like +49567892345 from 9 digits starting, can lead to OutOfMemoryErrors. So it would be better to split a number into groups like
to see, if you can make sense from the shorter parts. I wrote such a program, and tested some numbers from my friends, but found rarely combinations of shorter words, which could be checked in a dictionary for matching, not to mention single, long words.
So my decision was to only support searching, no full automation, by displaying possible combinations, encouraging splitting the number by hand, maybe multiple time.
So I found +-RAD JUNG (+-bycicle boy).
If you accept misspellings, abbreviations, foreign words, numbers as words, numbers in words, and names, your chance to find a solution is much better, than without fiddling around.
246848 => 2hot4u (too hot for you)
466368 => goodn8 (good night)
1325 => 1FCK (Football club)
53517 => JDK17 (Java Developer Kit)
are things a human might observe - to make an algorithm find such things is rather hard.
something like this ??
pretty-json
https://github.com/warfares/pretty-json
live sample:
In any sql server version you could use a variable for the total of all grades like this:
declare @countOfAll decimal(18, 4)
select @countOfAll = COUNT(*) from Grades
select
Grade, COUNT(*) / @countOfAll * 100
from Grades
group by Grade
You could also simply link both cells, and have an =Cell formula in each column like, =Sheet2!A2
in Sheet 1 A2 and =Sheet2!B2
in Sheet 1 B2, and drag it down, and then sort those two columns the way you want.
This would be better if your unique items change also, then all you would do is sort and be done.
just use this at the end of your button click event
protected void btnAddButton_Click(object sender, EventArgs e)
{
... save data routin
Response.Redirect(Request.Url.AbsoluteUri);
}
In addition to others' suggestions you can get CSRF token errors if your session storage is not working.
In a recent case a colleague of mine changed 'session_prefix' to a value that had a space in it.
session_prefix: 'My Website'
This broke session storage, which in turn meant my form could not obtain the CSRF token from the session.
function validateDate($date, $format = 'Y-m-d H:i:s')
{
$d = DateTime::createFromFormat($format, $date);
return $d && $d->format($format) == $date;
}
The javadoc for setParameter(String, Object)
is explicit, saying that the Object value must be non-null. It's a shame that it doesn't throw an exception if a null is passed in, though.
An alternative is setParameter(String, Object, Type)
, which does allow null values, although I'm not sure what Type
parameter would be most appropriate here.
If you did everything as in above answers, but a menu item is still visible, check that you reference to the unique resource. For instance, in onCreateOptionsMenu or onPrepareOptionsMenu
@Override
public void onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
MenuItem menuOpen = menu.findItem(R.id.menu_open);
menuOpen.setVisible(false);
}
Ctrl+Click R.id.menu_open and check that it exists only in one menu file. In case when this resource is already used anywhere and loaded in an activity, it will try to hide there.
I do not have factual evidence to prove this but I already ran into this issue. It seems that triggering a click() event on an <a>
tag doesn't seem to behave the same way you would expect with say, a input button.
The workaround I employed was to set the location.href property on the window which causes the browser to load the request resource like so:
$(document).ready(function()
{
var href = $('.cssbuttongo').attr('href');
window.location.href = href; //causes the browser to refresh and load the requested url
});
});
Edit:
I would make a js fiddle but the nature of the question intermixed with how jsfiddle uses an iframe to render code makes that a no go.
So If you present a view controller it will not show in navigation controller. It will just take complete screen. For this case you have to create another navigation controller and add your nextViewController
as root for this and present this new navigationController.
Another way is to just push the view controller.
self.presentViewController(nextViewController, animated:true, completion:nil)
For more info check Apple documentation:- https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIViewController_Class/#//apple_ref/doc/uid/TP40006926-CH3-SW96
Yet another (dynamic) way:
$("form").validate().settings.ignore = "*";
And to re-enable it, we just set back the default value:
$("form").validate().settings.ignore = ":hidden";

keytool
comes with the JDK installation (in the bin
folder):
keytool -importcert -file "your.cer" -keystore your.jks -alias "<anything>"
This will create a new keystore and add just your certificate to it.
So, you can't convert a certificate to a keystore: you add a certificate to a keystore.
You could use WebView.loadDataWithBaseURL
htmlData = "<link rel=\"stylesheet\" type=\"text/css\" href=\"style.css\" />" + htmlData;
// lets assume we have /assets/style.css file
webView.loadDataWithBaseURL("file:///android_asset/", htmlData, "text/html", "UTF-8", null);
And only after that WebView will be able to find and use css-files from the assets directory.
ps And, yes, if you load your html-file form the assets folder, you don't need to specify a base url.
Jenkins does not show coverage results as it is a problem of version compatibilities between jenkins jacoco plugin and maven jacoco plugin. On my side I have fixed it by using a more recent version of maven jacoco plugin

This code worked for me
.navbar .navbar-nav {
display: inline-block;
float: none;
}
.navbar .navbar-collapse {
text-align: center;
}
If you don't have the UITextView
handy (for example, you're sizing table view cells), you'll have to calculate the size by measuring the string, then accounting for the 8 pt of padding on each side of a UITextView
. For example, if you know the desired width of your text view and want to figure out the corresponding height:
NSString * string = ...;
CGFloat textViewWidth = ...;
UIFont * font = ...;
CGSize size = CGSizeMake(textViewWidth - 8 - 8, 100000);
size.height = [string sizeWithFont:font constrainedToSize:size].height + 8 + 8;
Here, each 8 is accounting for one of the four padded edges, and 100000 just serves as a very large maximum size.
In practice, you may want to add an extra font.leading
to the height; this adds a blank line below your text, which may look better if there are visually heavy controls directly beneath the text view.
Don't about the code but you can figure it out like this way :
Go into the 'window' tab then preferences->java->Installed JREs. You can add your own JRE(1.7 or 1.5 etc) also.
For changing the compliance level window->preferences->java->compiler. C Change the compliance level.
Java 8 introduced a new API for working with dates and times: the java.time package.
With java.time you can parse your count of whole seconds since the epoch reference of first moment of 1970 in UTC, 1970-01-01T00:00Z. The result is an Instant
.
Instant instant = Instant.ofEpochSecond( timeStamp );
If you need a java.util.Date
to interoperate with old code not yet updated for java.time, convert. Call new conversion methods added to the old classes.
Date date = Date.from( instant );
Adding to the crazy ideas: with Python 3 accepting unicode identifiers, you could declare a variable ? = frozenset()
(? is U+03D5) and use it instead.
You can use map
:
List<String> names =
personList.stream()
.map(Person::getName)
.collect(Collectors.toList());
EDIT :
In order to combine the Lists of friend names, you need to use flatMap
:
List<String> friendNames =
personList.stream()
.flatMap(e->e.getFriends().stream())
.collect(Collectors.toList());
#pragma pack
instructs the compiler to pack structure members with particular alignment. Most compilers, when you declare a struct, will insert padding between members to ensure that they are aligned to appropriate addresses in memory (usually a multiple of the type's size). This avoids the performance penalty (or outright error) on some architectures associated with accessing variables that are not aligned properly. For example, given 4-byte integers and the following struct:
struct Test
{
char AA;
int BB;
char CC;
};
The compiler could choose to lay the struct out in memory like this:
| 1 | 2 | 3 | 4 |
| AA(1) | pad.................. |
| BB(1) | BB(2) | BB(3) | BB(4) |
| CC(1) | pad.................. |
and sizeof(Test)
would be 4 × 3 = 12, even though it only contains 6 bytes of data. The most common use case for the #pragma
(to my knowledge) is when working with hardware devices where you need to ensure that the compiler does not insert padding into the data and each member follows the previous one. With #pragma pack(1)
, the struct above would be laid out like this:
| 1 |
| AA(1) |
| BB(1) |
| BB(2) |
| BB(3) |
| BB(4) |
| CC(1) |
And sizeof(Test)
would be 1 × 6 = 6.
With #pragma pack(2)
, the struct above would be laid out like this:
| 1 | 2 |
| AA(1) | pad.. |
| BB(1) | BB(2) |
| BB(3) | BB(4) |
| CC(1) | pad.. |
And sizeof(Test)
would be 2 × 4 = 8.
Order of variables in struct is also important. With variables ordered like following:
struct Test
{
char AA;
char CC;
int BB;
};
and with #pragma pack(2)
, the struct would be laid out like this:
| 1 | 2 |
| AA(1) | CC(1) |
| BB(1) | BB(2) |
| BB(3) | BB(4) |
and sizeOf(Test)
would be 3 × 2 = 6.
I had the same issue, and the answer was in the dmenu source code: the stest utility made for that purpose. You can compile the 'stest.c' and 'arg.h' files and it should work. There is a man page for the usage, that I put there for convenience:
STEST(1) General Commands Manual STEST(1)
NAME
stest - filter a list of files by properties
SYNOPSIS
stest [-abcdefghlpqrsuwx] [-n file] [-o file]
[file...]
DESCRIPTION
stest takes a list of files and filters by the
files' properties, analogous to test(1). Files
which pass all tests are printed to stdout. If no
files are given, stest reads files from stdin.
OPTIONS
-a Test hidden files.
-b Test that files are block specials.
-c Test that files are character specials.
-d Test that files are directories.
-e Test that files exist.
-f Test that files are regular files.
-g Test that files have their set-group-ID
flag set.
-h Test that files are symbolic links.
-l Test the contents of a directory given as
an argument.
-n file
Test that files are newer than file.
-o file
Test that files are older than file.
-p Test that files are named pipes.
-q No files are printed, only the exit status
is returned.
-r Test that files are readable.
-s Test that files are not empty.
-u Test that files have their set-user-ID flag
set.
-v Invert the sense of tests, only failing
files pass.
-w Test that files are writable.
-x Test that files are executable.
EXIT STATUS
0 At least one file passed all tests.
1 No files passed all tests.
2 An error occurred.

Frankly speaking, your case works fine for me!
I'm using Angular 5.
<script type='text/javascript'>
var base = window.location.href.substring(0, window.location.href.toLowerCase().indexOf('index.aspx'))
document.write('<base href="' + base + '" />');
</script>
Banging my usual drum solo of JUST TRY IT, here's how you can answer questions like that in the future:
$ cat junk.c
#include <stdio.h>
char* string = "Hello\0";
int main(int argv, char** argc)
{
printf("-->%s<--\n", string);
}
$ gcc -S junk.c
$ cat junk.s
... eliding the unnecessary parts ...
.LC0:
.string "Hello"
.string ""
...
.LC1:
.string "-->%s<--\n"
...
Note here how the string I used for printf is just "-->%s<---\n"
while the global string is in two parts: "Hello"
and ""
. The GNU assembler also terminates strings with an implicit NUL
character, so the fact that the first string (.LC0) is in those two parts indicates that there are two NUL
s. The string is thus 7 bytes long. Generally if you really want to know what your compiler is doing with a certain hunk of code, isolate it in a dummy example like this and see what it's doing using -S
(for GNU -- MSVC has a flag too for assembler output but I don't know it off-hand). You'll learn a lot about how your code works (or fails to work as the case may be) and you'll get an answer quickly that is 100% guaranteed to match the tools and environment you're working in.
You can return an object containing both values — there's nothing wrong with that.
Another strategy is to keep the value, via closures, instead of passing it through:
somethingAsync().then(afterSomething);
function afterSomething(amazingData) {
return processAsync(amazingData).then(function (processedData) {
// both amazingData and processedData are in scope here
});
}
Fully rather than partially inlined form (equivalent, arguably more consistent):
somethingAsync().then(function (amazingData) {
return processAsync(amazingData).then(function (processedData) {
// both amazingData and processedData are in scope here
});
}
In my situation, the problem was nginx docker container disk space. I had 10GB of logs and when I reduce this amount it works.
Enter in your container: docker exec -it <container_id> bash
Go to your logs, for example: cd /var/log/nginx
.
[optional] Show file size: ls -lh
for individual file size or du -h
for folder size.
Empty file(s) with > file_name
.
It works!.
Empty your nginx log with > file_name
or similar.
Hope it helps
It doesn't. There's a vague equivalent:
mycol VARCHAR(10) NOT NULL CHECK (mycol IN('Useful', 'Useless', 'Unknown'))
My naive assumption was that the size of scroll pane will be determined automatically...
The only solution that actually worked for me was explicitly seeting bounds of JScrollPane:
import javax.swing.*;
public class MyFrame extends JFrame {
public MyFrame()
{
setBounds(100, 100, 491, 310);
getContentPane().setLayout(null);
JTextArea textField = new JTextArea();
textField.setEditable(false);
String str = "";
for (int i = 0; i < 50; ++i)
str += "Some text\n";
textField.setText(str);
JScrollPane scroll = new JScrollPane(textField);
scroll.setBounds(10, 11, 455, 249); // <-- THIS
getContentPane().add(scroll);
setLocationRelativeTo ( null );
}
}
Maybe it will help some future visitors :)
You can also delete all tables from database using only MSSMS UI tools (without using SQL script). Sometimes this way can be more comfortable (especially if it is performed occasionally)
I do this step by step as follows:
In Bootstrap 4, the correct way to border your elements is to name them as follows in the class list of your elements:
For a slight rounding effect on all corners; class="rounded"
For a slight rounding on the left; class="rounded-left"
For a slight rounding on the top; class="rounded-top"
For a slight rounding on the right; class="rounded-right"
For a slight rounding on the bottom; class="rounded-bottom"
For a circle rounding, i.e. your element is made circular; class="rounded-circle"
And to remove rounding effects; class="rounded-0"
To use Bootstrap 4 css files, you can simply use the CDN, and use the following link in the of your HTML file:
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js" integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy" crossorigin="anonymous"></script>
This will provided you with the basics of Bootstrap 4. However if you would like to use the majority of Bootstrap 4 components, including tooltips, popovers, and dropdowns, then you are best to use the following code instead:
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js" integrity="sha384-ZMP7rVo3mIykV+2+9J3UJ46jBk0WLaUAdn689aCwoqbBJiSnjAK/l8WvCWPIPm49" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js" integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy" crossorigin="anonymous"></script>
Alternatively, you can install Bootstrap using NPM, or Bower, and link to the files there.
*Note that the bottom tag of the three is the same as the first tag in the first link path.
A full working example, could be :
<img src="path/to/my/image/image.jpg" width="150" height="150" class="rounded-circle mx-auto">
In the above example, the image is centered by using the Bootstrap auto margin on left and right.
In another way you can use window.location.href="your URL"
e.g.:
res.send('<script>window.location.href="your URL";</script>');
or:
return res.redirect("your url");
var getUrl = window.location;
var baseUrl = getUrl .protocol + "//" + getUrl.host + "/" + getUrl.pathname.split('/')[1];
Doesn't allow duplicates in the sense, It allow to add you but it does'nt care about this key already have a value or not. So at present for one key there will be only one value
It silently overrides the value
for null
key. No exception.
When you try to get, the last inserted value with null
will be return.
That is not only with null
and for any key.
Have a quick example
Map m = new HashMap<String, String>();
m.put("1", "a");
m.put("1", "b"); //no exception
System.out.println(m.get("1")); //b
Partial dependency implies is a situation where a non-prime attribute(An attribute that does not form part of the determinant(Primary key/Candidate key)) is functionally dependent to a portion/part of a primary key/Candidate key.
As noted before git-rebase(1) is your friend. Assuming the commits are in your master
branch, you would do:
git rebase --onto master~3 master~2 master
Before:
1---2---3---4---5 master
After:
1---2---4'---5' master
From git-rebase(1):
A range of commits could also be removed with rebase. If we have the following situation:
E---F---G---H---I---J topicA
then the command
git rebase --onto topicA~5 topicA~3 topicA
would result in the removal of commits F and G:
E---H'---I'---J' topicA
This is useful if F and G were flawed in some way, or should not be part of topicA. Note that the argument to --onto and the parameter can be any valid commit-ish.
you can add static
to make possible the initialization of this class member variable.
static const int i = 100;
However, this is not always a good practice to use inside class declaration, because all objects instacied from that class will shares the same static variable which is stored in internal memory outside of the scope memory of instantiated objects.
On client:
axios.get('/api', {
params: {
foo: 'bar'
}
});
On server:
function get(req, res, next) {
let param = req.query.foo

string t = DateTime.Now.ToString("h/m/s tt");
string t2 = DateTime.Now.ToString("hh:mm:ss tt");
string d = DateTime.Now.ToString("MM/dd/yy");
in SQL 2008 a new TSQL statement "MERGE" is introduced which performs insert, update, or delete operations on a target table based on the results of a join with a source table. You can synchronize two tables by inserting, updating, or deleting rows in one table based on differences found in the other table.

First off - check with Firebug(or what ever your preference is) whether the css property is being interpreted by the browser. Sometimes the tool used will give you the problem right there, so no more hunting.
Second off - check compatibility: http://caniuse.com/#feat=calc
And third - I ran into some problems a few hours ago and just resolved it. It's the smallest thing but it kept me busy for 30 minutes.
Here's how my CSS looked
#someElement {
height:calc(100%-100px);
height:-moz-calc(100%-100px);
height:-webkit-calc(100%-100px);
}
Looks right doesn't it? WRONG Here's how it should look:
#someElement {
height:calc(100% - 100px);
height:-moz-calc(100% - 100px);
height:-webkit-calc(100% - 100px);
}
Looks the same right?
Notice the spaces!!! Checked android browser, Firefox for android, Chrome for android, Chrome and Firefox for Windows and Internet Explorer 11. All of them ignored the CSS if there were no spaces.
Hope this helps someone.
You still need to worry about memory when you are writing managed code unless your application is trivial. I will suggest two things: first, read CLR via C# because it will help you understand memory management in .NET. Second, learn to use a tool like CLRProfiler (Microsoft). This can give you an idea of what is causing your memory leak (e.g. you can take a look at your large object heap fragmentation)

I made a fairly complicated GIS app as an experiment with it some years ago (database, complex gui, reports, client/server). It was a pleasant experience (apart from some documentation issues...) and I became productive with it very fast.
I don't use it anymore mainly because:
Strings are immutable, so actully you can't change the String afterwards (you can only make the variable that held the String object point to a different String object).
However, that is not the reason why you can bind any variable to a final
parameter. All the compiler checks is that the parameter is not reassigned within the method. This is good for documentation purposes, arguably good style, and may even help optimize the byte code for speed (although this seems not to do very much in practice).
But even if you do reassign a parameter within a method, the caller doesn't notice that, because java does all parameter passing by value. After the sequence
a = someObject();
process(a);
the fields of a may have changed, but a is still the same object it was before. In pass-by-reference languages this may not be true.
php test.php
should do it, or
php -f test.php
to be explicit.
When you compare update_date >= '2013-05-03'
postgres casts values to the same type to compare values. So your '2013-05-03' was casted to '2013-05-03 00:00:00'.
So for update_date = '2013-05-03 14:45:00' your expression will be that:
'2013-05-03 14:45:00' >= '2013-05-03 00:00:00' AND '2013-05-03 14:45:00' <= '2013-05-03 00:00:00'
This is always false
To solve this problem cast update_date to date
:
select * from table where update_date::date >= '2013-05-03' AND update_date::date <= '2013-05-03' -> Will return result
conio.h
is a C
header file used in old MS-DOS compilers to create text user interfaces. Compilers that targeted non-DOS operating systems, such as Linux, Win32 and OS/2, provided different implementations of these functions.
The #include <curses.h>
will give you almost all the functionalities that was provided in conio.h
nucurses need to be installed at the first place
In deb based Distros use
sudo apt-get install libncurses5-dev libncursesw5-dev
And in rpm based distros use
sudo yum install ncurses-devel ncurses

Here is a way to write data from a dataframe into an excel file by different IDs and into different tabs (sheets) by another ID associated to the first level id. Imagine you have a dataframe that has email_address
as one column for a number of different users, but each email has a number of 'sub-ids' that have all the data.
data <- tibble(id = c(1,2,3,4,5,6,7,8,9), email_address = c(rep('[email protected]',3), rep('[email protected]', 3), rep('[email protected]', 3)))
So ids 1,2,3
would be associated with [email protected]
. The following code splits the data by email and then puts 1,2,3
into different tabs. The important thing is to set append = True
when writing the .xlsx
file.
temp_dir <- tempdir()
for(i in unique(data$email_address)){
data %>%
filter(email_address == i) %>%
arrange(id) -> subset_data
for(j in unique(subset_data$id)){
write.xlsx(subset_data %>% filter(id == j),
file = str_c(temp_dir,"/your_filename_", str_extract(i, pattern = "\\b[A-Za-z0-
9._%+-]+"),'_', Sys.Date(), '.xlsx'),
sheetName = as.character(j),
append = TRUE)}
}
The regex gets the name from the email address and puts it into the file-name.
Hope somebody finds this useful. I'm sure there's more elegant ways of doing this but it works.
Btw, here is a way to then send these individual files to the various email addresses in the data.frame
. Code goes into second loop [j]
send.mail(from = "[email protected]",
to = i,
subject = paste("Your report for", str_extract(i, pattern = "\\b[A-Za-z0-9._%+-]+"), 'on', Sys.Date()),
body = "Your email body",
authenticate = TRUE,
smtp = list(host.name = "XXX", port = XXX,
user.name = Sys.getenv("XXX"), passwd = Sys.getenv("XXX")),
attach.files = str_c(temp_dir, "/your_filename_", str_extract(i, pattern = "\\b[A-Za-z0-9._%+-]+"),'_', Sys.Date(), '.xlsx'))
If you use fragments you can prepare XML layout and than stratch critical elements programmatically
int thirdScreenWidth = (int)(screenWidth *0.33);
View view = inflater.inflate(R.layout.fragment_second, null);
View _container = view.findViewById(R.id.rim1container);
_container.getLayoutParams().width = thirdScreenWidth * 2;
_container = view.findViewById(R.id.rim2container);
_container.getLayoutParams().width = screenWidth - thirdScreenWidth * 2;
_container = view.findViewById(R.id.rim3container);
_container.getLayoutParams().width = screenWidth - thirdScreenWidth * 2;
This layout for 3 equal columns. First element takes 2x2 Result in the picture
There is a serious problem with using
String[] strArr=line.split(",");
in order to parse CSV files, and that is because there can be commas within the data values, and in that case you must quote them, and ignore commas between quotes.
There is a very very simple way to parse this:
/**
* returns a row of values as a list
* returns null if you are past the end of the input stream
*/
public static List<String> parseLine(Reader r) throws Exception {
int ch = r.read();
while (ch == '\r') {
//ignore linefeed chars wherever, particularly just before end of file
ch = r.read();
}
if (ch<0) {
return null;
}
Vector<String> store = new Vector<String>();
StringBuffer curVal = new StringBuffer();
boolean inquotes = false;
boolean started = false;
while (ch>=0) {
if (inquotes) {
started=true;
if (ch == '\"') {
inquotes = false;
}
else {
curVal.append((char)ch);
}
}
else {
if (ch == '\"') {
inquotes = true;
if (started) {
// if this is the second quote in a value, add a quote
// this is for the double quote in the middle of a value
curVal.append('\"');
}
}
else if (ch == ',') {
store.add(curVal.toString());
curVal = new StringBuffer();
started = false;
}
else if (ch == '\r') {
//ignore LF characters
}
else if (ch == '\n') {
//end of a line, break out
break;
}
else {
curVal.append((char)ch);
}
}
ch = r.read();
}
store.add(curVal.toString());
return store;
}
There are many advantages to this approach. Note that each character is touched EXACTLY once. There is no reading ahead, pushing back in the buffer, etc. No searching ahead to the end of the line, and then copying the line before parsing. This parser works purely from the stream, and creates each string value once. It works on header lines, and data lines, you just deal with the returned list appropriate to that. You give it a reader, so the underlying stream has been converted to characters using any encoding you choose. The stream can come from any source: a file, a HTTP post, an HTTP get, and you parse the stream directly. This is a static method, so there is no object to create and configure, and when this returns, there is no memory being held.
You can find a full discussion of this code, and why this approach is preferred in my blog post on the subject: The Only Class You Need for CSV Files.
Hey I was also facing similar problem, in an ajax generated page.. I took generated source using Webdeveloper pluggin in FF, and checked all the inputs in the form and found out that there was another checkbox inside a hidden div(display:none) with same ID, Once I changed the id of second checkbox, it started working.. You can also try that.. and let me know the result.. cheers
I'm not sure if I understood correctly, but is this what you mean?
out.write("this is line 1");
out.newLine();
out.write("this is line 2");
out.newLine();

You can directly show image from web without downloading it. Please check the below function . It will show the images from the web into your image view.
public static Drawable LoadImageFromWebOperations(String url) {
try {
InputStream is = (InputStream) new URL(url).getContent();
Drawable d = Drawable.createFromStream(is, "src name");
return d;
} catch (Exception e) {
return null;
}
}
then set image to imageview using code in your activity.
You could try the following:
import matplotlib.pyplot as plt
import numpy as np
def plot_figures(figures, nrows = 1, ncols=1):
"""Plot a dictionary of figures.
Parameters
----------
figures : <title, figure> dictionary
ncols : number of columns of subplots wanted in the display
nrows : number of rows of subplots wanted in the figure
"""
fig, axeslist = plt.subplots(ncols=ncols, nrows=nrows)
for ind,title in zip(range(len(figures)), figures):
axeslist.ravel()[ind].imshow(figures[title], cmap=plt.jet())
axeslist.ravel()[ind].set_title(title)
axeslist.ravel()[ind].set_axis_off()
plt.tight_layout() # optional
# generation of a dictionary of (title, images)
number_of_im = 20
w=10
h=10
figures = {'im'+str(i): np.random.randint(10, size=(h,w)) for i in range(number_of_im)}
# plot of the images in a figure, with 5 rows and 4 columns
plot_figures(figures, 5, 4)
plt.show()
However, this is basically just copy and paste from here: Multiple figures in a single window for which reason this post should be considered to be a duplicate.
I hope this helps.
According to Github API two empty lines are a new paragraph (same as here in stackoverflow)
You can test it with http://prose.io
I used:
echo exec('whoami');
to find out who is running the script (say username), and then gave the user permissions to the entire application directory, like:
sudo chown -R :username /var/www/html/myapp
Hope this helps someone out there.
This works fine for me:
while True:
answer = input('Do you want to continue?:')
if answer.lower().startswith("y"):
print("ok, carry on then")
elif answer.lower().startswith("n"):
print("sayonara, Robocop")
exit()
edit: use input
in python 3.2 instead of raw_input
Converting the String to JsonNode using ObjectMapper object :
ObjectMapper mapper = new ObjectMapper();
// For text string
JsonNode = mapper.readValue(mapper.writeValueAsString("Text-string"), JsonNode.class)
// For Array String
JsonNode = mapper.readValue("[\"Text-Array\"]"), JsonNode.class)
// For Json String
String json = "{\"id\" : \"1\"}";
ObjectMapper mapper = new ObjectMapper();
JsonFactory factory = mapper.getFactory();
JsonParser jsonParser = factory.createParser(json);
JsonNode node = mapper.readTree(jsonParser);
Without seeing said object list, I believe you should be binding to the DataGrid's ItemsSource
property, not its DataContext
.
<DataGrid x:Name="Imported" VerticalAlignment="Top" ItemsSource="{Binding Source=list}" AutoGenerateColumns="False" CanUserResizeColumns="True">
<DataGrid.Columns>
<DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
<DataGridTextColumn Header="Date" Binding="{Binding Date}"/>
</DataGrid.Columns>
</DataGrid>
(This assumes that the element [UserControl, etc.] that contains the DataGrid has its DataContext bound to an object that contains the list
collection. The DataGrid is derived from ItemsControl
, which relies on its ItemsSource
property to define the collection it binds its rows to. Hence, if list
isn't a property of an object bound to your control's DataContext, you might need to set both DataContext={Binding list}
and ItemsSource={Binding list}
on the DataGrid...)
Upfront, I am a bit lacking in my GIT skills.
That is going to clone a bare repository on your machine, which only contains the folders within .git
which is a hidden directory. execute ls -al
and you should see .git
or cd .git
inside your repository.
Can you add a description of your intent so that someone with more GIT skills can help? What is it you really want to do not how you plan on doing it?

Accepted answer is certainly a good solution, but here is the way I went about generating a CSV and serving it from a view.
Thought it was worth while putting this here as it took me a little bit of fiddling to get all the desirable behaviour (overwrite existing file, storing to the right spot, not creating duplicate files etc).

Each instantiation and full specialization of std::atomic<> represents a type that different threads can simultaneously operate on (their instances), without raising undefined behavior:
Objects of atomic types are the only C++ objects that are free from data races; that is, if one thread writes to an atomic object while another thread reads from it, the behavior is well-defined.
In addition, accesses to atomic objects may establish inter-thread synchronization and order non-atomic memory accesses as specified by
std::memory_order
.
std::atomic<>
wraps operations that, in pre-C++ 11 times, had to be performed using (for example) interlocked functions with MSVC or atomic bultins in case of GCC.
Also, std::atomic<>
gives you more control by allowing various memory orders that specify synchronization and ordering constraints. If you want to read more about C++ 11 atomics and memory model, these links may be useful:
Note that, for typical use cases, you would probably use overloaded arithmetic operators or another set of them:
std::atomic<long> value(0);
value++; //This is an atomic op
value += 5; //And so is this
Because operator syntax does not allow you to specify the memory order, these operations will be performed with std::memory_order_seq_cst
, as this is the default order for all atomic operations in C++ 11. It guarantees sequential consistency (total global ordering) between all atomic operations.
In some cases, however, this may not be required (and nothing comes for free), so you may want to use more explicit form:
std::atomic<long> value {0};
value.fetch_add(1, std::memory_order_relaxed); // Atomic, but there are no synchronization or ordering constraints
value.fetch_add(5, std::memory_order_release); // Atomic, performs 'release' operation
Now, your example:
a = a + 12;
will not evaluate to a single atomic op: it will result in a.load()
(which is atomic itself), then addition between this value and 12
and a.store()
(also atomic) of final result. As I noted earlier, std::memory_order_seq_cst
will be used here.
However, if you write a += 12
, it will be an atomic operation (as I noted before) and is roughly equivalent to a.fetch_add(12, std::memory_order_seq_cst)
.
As for your comment:
A regular
int
has atomic loads and stores. Whats the point of wrapping it withatomic<>
?
Your statement is only true for architectures that provide such guarantee of atomicity for stores and/or loads. There are architectures that do not do this. Also, it is usually required that operations must be performed on word-/dword-aligned address to be atomic std::atomic<>
is something that is guaranteed to be atomic on every platform, without additional requirements. Moreover, it allows you to write code like this:
void* sharedData = nullptr;
std::atomic<int> ready_flag = 0;
// Thread 1
void produce()
{
sharedData = generateData();
ready_flag.store(1, std::memory_order_release);
}
// Thread 2
void consume()
{
while (ready_flag.load(std::memory_order_acquire) == 0)
{
std::this_thread::yield();
}
assert(sharedData != nullptr); // will never trigger
processData(sharedData);
}
Note that assertion condition will always be true (and thus, will never trigger), so you can always be sure that data is ready after while
loop exits. That is because:
store()
to the flag is performed after sharedData
is set (we assume that generateData()
always returns something useful, in particular, never returns NULL
) and uses std::memory_order_release
order:
memory_order_release
A store operation with this memory order performs the release operation: no reads or writes in the current thread can be reordered after this store. All writes in the current thread are visible in other threads that acquire the same atomic variable
sharedData
is used after while
loop exits, and thus after load()
from flag will return a non-zero value. load()
uses std::memory_order_acquire
order:
std::memory_order_acquire
A load operation with this memory order performs the acquire operation on the affected memory location: no reads or writes in the current thread can be reordered before this load. All writes in other threads that release the same atomic variable are visible in the current thread.
This gives you precise control over the synchronization and allows you to explicitly specify how your code may/may not/will/will not behave. This would not be possible if only guarantee was the atomicity itself. Especially when it comes to very interesting sync models like the release-consume ordering.
One easy solution is to use overflow
values other than visible
to make the text flex basis width reset as expected.
Here with value auto
the text wraps as expected and the article content does not overflow main container.
Also, the article flex
value must either have a auto
basis AND be able to shrink, OR, only grow AND explicit 0
basis

As you've noted HttpServletRequest
does not have a setParameter method. This is deliberate, since the class represents the request as it came from the client, and modifying the parameter would not represent that.
One solution is to use the HttpServletRequestWrapper
class, which allows you to wrap one request with another. You can subclass that, and override the getParameter
method to return your sanitized value. You can then pass that wrapped request to chain.doFilter
instead of the original request.
It's a bit ugly, but that's what the servlet API says you should do. If you try to pass anything else to doFilter
, some servlet containers will complain that you have violated the spec, and will refuse to handle it.
A more elegant solution is more work - modify the original servlet/JSP that processes the parameter, so that it expects a request attribute instead of a parameter. The filter examines the parameter, sanitizes it, and sets the attribute (using request.setAttribute
) with the sanitized value. No subclassing, no spoofing, but does require you to modify other parts of your application.

You can use Joda time library for Java. It would be much easier to calculate time-diff between dates with it.
Sample snippet for time-diff:
Days d = Days.daysBetween(startDate, endDate);
int days = d.getDays();

With docker 1.10, you now have new commands for data-volume containers.
(for regular containers, see the next section, for docker 1.8+):
With docker 1.8.1 (August 2015), a docker inspect -f '{{ .Volumes }}' containerid
would be empty!
You now need to check Mounts
, which is a list of mounted paths like:
"Mounts": [
{
"Name": "7ced22ebb63b78823f71cf33f9a7e1915abe4595fcd4f067084f7c4e8cc1afa2",
"Source": "/mnt/sda1/var/lib/docker/volumes/7ced22ebb63b78823f71cf33f9a7e1915abe4595fcd4f067084f7c4e8cc1afa2/_data",
"Destination": "/home/git/repositories",
"Driver": "local",
"Mode": "",
"RW": true
}
],
If you want the path of the first mount (for instance), that would be (using index 0):
docker inspect -f '{{ (index .Mounts 0).Source }}' containerid
As Mike Mitterer comments below:
Pretty print the whole thing:
docker inspect -f '{{ json .Mounts }}' containerid | python -m json.tool
Or, as commented by Mitja, use the jq
command.
docker inspect -f '{{ json .Mounts }}' containerid | jq
None of these suggestions above worked for me as-is. I had to use the following to center a checkbox with the label text displayed to the right of the box:
<style>
.checkboxes {
display: flex;
justify-content: center;
align-items: center;
vertical-align: middle;
word-wrap: break-word;
}
</style>
<label for="checkbox1" class="checkboxes"><input type="checkbox" id="checkbox1" name="checked" value="yes" class="checkboxes"/>
Check the box.</label>

A great related question is: How the heck do you figure this out using the --help
option of git? Let's try this:
git branch --help
We see this output:
NAME
git-branch - List, create, or delete branches
SYNOPSIS
git branch [--color[=<when>] | --no-color] [-r | -a]
[--list] [-v [--abbrev=<length> | --no-abbrev]]
[--column[=<options>] | --no-column]
[(--merged | --no-merged | --contains) [<commit>]] [--sort=<key>]
[--points-at <object>] [<pattern>...]
git branch [--set-upstream | --track | --no-track] [-l] [-f] <branchname> [<start-point>]
git branch (--set-upstream-to=<upstream> | -u <upstream>) [<branchname>]
git branch --unset-upstream [<branchname>]
git branch (-m | -M) [<oldbranch>] <newbranch>
git branch (-d | -D) [-r] <branchname>...
git branch --edit-description [<branchname>]
Gobbledegook.
Search through the subsequent text for the word "commit". We find this:
<start-point>
The new branch head will point to this commit. It may be given as a branch name, a
commit-id, or a tag. If this option is omitted, the current HEAD will be used instead.
We're getting somewhere!
Now, focus on this line of the gobbledegook:
git branch [--set-upstream | --track | --no-track] [-l] [-f] <branchname> [<start-point>]
Condense that to this:
git branch <branchname> [<start-point>]
And done.
Compilr seems to be going in that direction: http://compilr.com/teachers
As it says, it is ambiguous. Your array comparison returns a boolean array. Methods any() and all() reduce values over the array (either logical_or or logical_and). Moreover, you probably don't want to check for equality. You should replace your condition with:
np.allclose(A.dot(eig_vec[:,col]), eig_val[col] * eig_vec[:,col])
I had this problem and found that removing the following folder helped, even with the non-Express edition.Express:
C:\Users\<user>\Documents\IISExpress
In SSMS expand your database in Object Explorer, go to Tables, right click on the table you're interested in and select Script Table As, Create To, New Query Editor Window.
Do a find and replace (CTRL + H) to change the table name (i.e. put ABC
in the Find What field and ABC_1
in the Replace With then click OK).
The other answers showing how to do this by SQL also work well, but the difference with this method is you'll also get any indexes, constraints and triggers.
If you want to include data, after creating this table run the below script to copy all data from ABC (keeping the same ID values if you have an identity field):
set identity_insert ABC_1 on
insert into ABC_1 (column1, column2) select column1, column2 from ABC
set identity_insert ABC_1 off
You can use ax.figure.savefig()
:
import pandas as pd
s = pd.Series([0, 1])
ax = s.plot.hist()
ax.figure.savefig('demo-file.pdf')
This has no practical benefit over ax.get_figure().savefig()
as suggested in Philip Cloud's answer, so you can pick the option you find the most aesthetically pleasing. In fact, get_figure()
simply returns self.figure
:
# Source from snippet linked above
def get_figure(self):
"""Return the `.Figure` instance the artist belongs to."""
return self.figure
Let me try to explain my understanding with the help of four examples. Java is pass-by-value, and not pass-by-reference
/**
Pass By Value
In Java, all parameters are passed by value, i.e. assigning a method argument is not visible to the caller.
*/
Example 1:
public class PassByValueString {
public static void main(String[] args) {
new PassByValueString().caller();
}
public void caller() {
String value = "Nikhil";
boolean valueflag = false;
String output = method(value, valueflag);
/*
* 'output' is insignificant in this example. we are more interested in
* 'value' and 'valueflag'
*/
System.out.println("output : " + output);
System.out.println("value : " + value);
System.out.println("valueflag : " + valueflag);
}
public String method(String value, boolean valueflag) {
value = "Anand";
valueflag = true;
return "output";
}
}
Result
output : output
value : Nikhil
valueflag : false
Example 2:
/** * * Pass By Value * */
public class PassByValueNewString {
public static void main(String[] args) {
new PassByValueNewString().caller();
}
public void caller() {
String value = new String("Nikhil");
boolean valueflag = false;
String output = method(value, valueflag);
/*
* 'output' is insignificant in this example. we are more interested in
* 'value' and 'valueflag'
*/
System.out.println("output : " + output);
System.out.println("value : " + value);
System.out.println("valueflag : " + valueflag);
}
public String method(String value, boolean valueflag) {
value = "Anand";
valueflag = true;
return "output";
}
}
Result
output : output
value : Nikhil
valueflag : false
Example 3:
/** This 'Pass By Value has a feeling of 'Pass By Reference'
Some people say primitive types and 'String' are 'pass by value' and objects are 'pass by reference'.
But from this example, we can understand that it is infact pass by value only, keeping in mind that here we are passing the reference as the value. ie: reference is passed by value. That's why are able to change and still it holds true after the local scope. But we cannot change the actual reference outside the original scope. what that means is demonstrated by next example of PassByValueObjectCase2.
*/
public class PassByValueObjectCase1 {
private class Student {
int id;
String name;
public Student() {
}
public Student(int id, String name) {
super();
this.id = id;
this.name = name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}

this.name = name;
}
@Override
public String toString() {
return "Student [id=" + id + ", name=" + name + "]";
}
}

new PassByValueObjectCase1().caller();
}
public void caller() {
Student student = new Student(10, "Nikhil");
String output = method(student);

* 'output' is insignificant in this example. we are more interested in
* 'student'
*/
System.out.println("output : " + output);
System.out.println("student : " + student);
}
public String method(Student student) {
student.setName("Anand");
return "output";
}
}
Result
output : output
student : Student [id=10, name=Anand]
Example 4:
/**
In addition to what was mentioned in Example3 (PassByValueObjectCase1.java), we cannot change the actual reference outside the original scope."
Note: I am not pasting the code for private class Student
. The class definition for Student
is same as Example3.
*/
public class PassByValueObjectCase2 {
public static void main(String[] args) {
new PassByValueObjectCase2().caller();
}
public void caller() {
// student has the actual reference to a Student object created
// can we change this actual reference outside the local scope? Let's see
Student student = new Student(10, "Nikhil");
String output = method(student);
/*
* 'output' is insignificant in this example. we are more interested in
* 'student'
*/
System.out.println("output : " + output);
System.out.println("student : " + student); // Will it print Nikhil or Anand?

}
}
Result
output : output
student : Student [id=10, name=Nikhil]
The first response to the question is the simplest solution: "Environment.Exit(1)" I am using this on Windows Server 2008 R2 and it works perfectly. The service stops itself, the O/S waits 1 minute, then restarts it.
if((Type == 2 && PageCount == 0) || (Type == 2 && PageCount == '')) {
PageCount= document.getElementById('<%=hfPageCount.ClientID %>').value;
}
This could be one of possible solutions, so 'or' is || not !!
This happens because Access Privilege varies from OS to OS. Windows access hierarchy is different from Unix. However, this could be overcome by following these simple steps:
AccessController.doPrivileged(java.security.PrivilegedAction subclass)
java.security.Provider
subclass as security property.
a. Security.insertProviderAt(new , 2);Security.setProperty("ssl.TrustManagerFactory.algorithm" , “XTrust509”);
pd.DataFrame(df.to_records()) # multiindex become columns and new index is integers only
This is a rough RegExp function I would have come up with (it's untested)
function isVowel(char) {
return /^[aeiou]$/.test(char.toLowerCase());
}
Which means, if (char.length == 1 && 'aeiou' is contained in char.toLowerCase()) then return true
.
One way to do this is to create an instance of the ofstream class, and use it to write to your file. Here's a link to a website that has some example code, and some more information about the standard tools available with most implementations of C++:
For completeness, here's some example code:
// using ofstream constructors.
#include <iostream>
#include <fstream>
std::ofstream outfile ("test.txt");
outfile << "my text here!" << std::endl;
outfile.close();
You want to use std::endl to end your lines. An alternative is using '\n' character. These two things are different, std::endl flushes the buffer and writes your output immediately while '\n' allows the outfile to put all of your output into a buffer and maybe write it later.
Solution 0
This can be accompished using pivot tables.
Solution 1
Use the unique
formula to get all the distinct values. Then use countif
to get the count of each value. See the working example link at the top to see exactly how this is implemented.
Unique Values Count
=UNIQUE(A3:A8) =COUNTIF(A3:A8;B3)
=COUNTIF(A3:A8;B4)
...
Solution 2
If you setup your data as such:
City
----
London 1
Paris 1
London 1
Berlin 1
Rome 1
Paris 1
Then the following will produce the desired result.
=sort(transpose(query(A3:B8,"Select sum(B) pivot (A)")),2,FALSE)
I'm sure there is a way to get rid of the second column since all values will be 1. Not an ideal solution in my opinion.

You can use the Build Class to get the device information.
For example:

Very nice problem. I'd go for using a set difference for Qk. A lot of programming languages even have support for it, like in Ruby:
missing = (1..100).to_a - bag
It's probably not the most efficient solution but it's one I would use in real life if I was faced with such a task in this case (known boundaries, low boundaries). If the set of number would be very large then I would consider a more efficient algorithm, of course, but until then the simple solution would be enough for me.
I know that best way is str.indexOf(s) !== -1;

Your /home/gnu/bin/c++
seem to require additional flag to link things properly and CMake doesn't know about that.
To use /usr/bin/c++
as your compiler run cmake
with -DCMAKE_CXX_COMPILER=/usr/bin/c++
.
Also, CMAKE_PREFIX_PATH
variable sets destination dir where your project' files should be installed. It has nothing to do with CMake installation prefix and CMake itself already know this.
In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj)
in your ModelForm.save
override, as ModelForm.save
later populates your m2m from self.cleaned_data['my_m2m']
which overwrites your changes. Instead call:
my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms
(It is fine to convert the incoming QuerySet to a list - the ManyToManyField
does that anyway.)
You could simply get the character length of the current directory, and remove them from your absolute list
setlocal EnableDelayedExpansion

setlocal DisableDelayedExpansion

setlocal EnableDelayedExpansion
set "relPath=!absPath:~%len%!"
echo(!relPath!

re: Windows users
No. Don't remove the Javapath environment reference from your PATH variable.
The reason why the registry didn't work is that the Oracle Javapath script needs to run in the PATH sequence ahead of the JRE & JDK directories - it will sort out the current version:
put this directory at the HEAD of your %PATH%
variable:
C:\ProgramData\Oracle\Java\javapath
[or wherever it is on your desktop]
so your PATH will look something like this - mine for example
PATH=C:\ProgramData\Oracle\Java\javapath;<other path directories>;E:\Program Files\Java\jdk1.8.0_77\bin;E:\Program Files\Java\jre1.8.0_77\bin
You will then see the correct, current version:
C:\>java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)
As Heinzi said, an array has a fixed size. In order to 'remove an item' or 'resize' it, you'll have to create a new array with the desired size and copy the items you need as appropriate.
Here's code to remove an item from an array:
<System.Runtime.CompilerServices.Extension()> _
Function RemoveAt(Of T)(ByVal arr As T(), ByVal index As Integer) As T()
Dim uBound = arr.GetUpperBound(0)
Dim lBound = arr.GetLowerBound(0)
Dim arrLen = uBound - lBound
If index < lBound OrElse index > uBound Then
Throw New ArgumentOutOfRangeException( _
String.Format("Index must be from {0} to {1}.", lBound, uBound))
Else
'create an array 1 element less than the input array
Dim outArr(arrLen - 1) As T
'copy the first part of the input array
Array.Copy(arr, 0, outArr, 0, index)
'then copy the second part of the input array
Array.Copy(arr, index + 1, outArr, index, uBound - index)
Return outArr
End If
End Function
You can use it as such:
Module Module1
Sub Main()
Dim arr = New String() {"abc", "mno", "xyz"}
arr.RemoveAt(1)
End Sub
End Module
The code above removes the second element ("mno"
) [which has an index of 1] from the array.
You need to be developing in .NET 3.5 or higher in order to use the extension method. If you're using .NET 2.0 or 3.0, you can call the method as such
arr = RemoveAt(arr, 1)
I hope this is what you need.
After running tests based on ToolMakerSteve's comment it appears the initial code does not modify the array you want to update because of the ByVal
used in the function's declaration. However, writing code like arr = arr.RemoveAt(1)
or arr = RemoveAt(arr, 1)
does modify the array because it reassigns the modified array to the original.
Find below the updated method (subroutine) for removing an element from an array.
<System.Runtime.CompilerServices.Extension()> _
Public Sub RemoveAt(Of T)(ByRef arr As T(), ByVal index As Integer)
Dim uBound = arr.GetUpperBound(0)
Dim lBound = arr.GetLowerBound(0)
Dim arrLen = uBound - lBound
If index < lBound OrElse index > uBound Then
Throw New ArgumentOutOfRangeException( _
String.Format("Index must be from {0} to {1}.", lBound, uBound))
Else
'create an array 1 element less than the input array
Dim outArr(arrLen - 1) As T
'copy the first part of the input array
Array.Copy(arr, 0, outArr, 0, index)
'then copy the second part of the input array
Array.Copy(arr, index + 1, outArr, index, uBound - index)
arr = outArr
End If
End Sub
Usage of the method is similar to the original, except there is no return value this time so trying to assign an array from the return value will not work because nothing is returned.
Dim arr = New String() {"abc", "mno", "xyz"}
arr.RemoveAt(1) ' Output: {"abc", "mno"} (works on .NET 3.5 and higher)
RemoveAt(arr, 1) ' Output: {"abc", "mno"} (works on all versions of .NET fx)
arr = arr.RemoveAt(1) 'will not work; no return value
arr = RemoveAt(arr, 1) 'will not work; no return value
Note:
I use a temporary array for the process because it makes my intentions clear and that is exactly what VB.NET does behind the scenes when you do Redim Preserve
. If you would like to modify the array in-place using Redim Preserve
, see ToolmakerSteve's answer.
The RemoveAt
methods written here are extension methods. In order for them to work, you will have to paste them in a Module
. Extension methods will not work in VB.NET if they are placed in a Class
.
Important If you will be modifying your array with lots of 'removes', it is highly recommended to use a different data structure such as List(Of T)
as suggested by other answerers to this question.
You can get the IP address from hostvars
, dict ansible_default_ipv4
and key address
hostvars[inventory_hostname]['ansible_default_ipv4']['address']
and IPv6 address respectively
hostvars[inventory_hostname]['ansible_default_ipv6']['address']
An example playbook:
---
- hosts: localhost
tasks:
- debug: var=hostvars[inventory_hostname]['ansible_default_ipv4']['address']
- debug: var=hostvars[inventory_hostname]['ansible_default_ipv6']['address']
An iframe is used to embed another document inside a html page.
If the form is to be submitted to an iframe within the form page, then it can be easily acheived using the target attribute of the tag.
Set the target attribute of the form to the name of the iframe tag.
<form action="action" method="post" target="output_frame">
<!-- input elements here -->
</form>
<iframe name="output_frame" src="" id="output_frame" width="XX" height="YY">
</iframe>
Advanced iframe target use
This property can also be used to produce an ajax like experience, especially in cases like file upload, in which case where it becomes mandatory to submit the form, in order to upload the files
The iframe can be set to a width and height of 0, and the form can be submitted with the target set to the iframe, and a loading dialog opened before submitting the form. So, it mocks a ajax control as the control still remains on the input form jsp, with the loading dialog open.
Exmaple
<script>
$( "#uploadDialog" ).dialog({ autoOpen: false, modal: true, closeOnEscape: false,
open: function(event, ui) { jQuery('.ui-dialog-titlebar-close').hide(); } });
function startUpload()
{
$("#uploadDialog").dialog("open");
}
function stopUpload()
{
$("#uploadDialog").dialog("close");
}
</script>
<div id="uploadDialog" title="Please Wait!!!">
<center>
<img src="/imagePath/loading.gif" width="100" height="100"/>
<br/>
Loading Details...
</center>
</div>
<FORM ENCTYPE="multipart/form-data" ACTION="Action" METHOD="POST" target="upload_target" onsubmit="startUpload()">
<!-- input file elements here-->
</FORM>
<iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;" onload="stopUpload()">
</iframe>
you could get just the first row like:
with open('some.csv', newline='') as f:
csv_reader = csv.reader(f)
csv_headings = next(csv_reader)
first_line = next(csv_reader)
Using either a float or a double value in a C expression will result in a value that is a double anyway, so printf can't tell the difference. Whereas a pointer to a double has to be explicitly signalled to scanf as distinct from a pointer to float, because what the pointer points to is what matters.
You can't format the Date
itself. You can only get the formatted result in String
. Use SimpleDateFormat
as mentioned by others.
Moreover, most of the getter methods in Date
are deprecated.
svn merge -r 854:853 l3toks.dtx

private T GetHeaderControl<T>(Repeater rp, string id) where T : Control
{
T returnValue = null;
if (rp != null && !String.IsNullOrWhiteSpace(id))
{
returnValue = rp.Controls.Cast<RepeaterItem>().Where(i => i.ItemType == ListItemType.Header).Select(h => h.FindControl(id) as T).Where(c => c != null).FirstOrDefault();
}
return returnValue;
}
Finds and casts the control. (Based on Piyey's VB answer)
You need to make sure requestAnimFrame stops being called once game == 1. A break statement only exits a traditional loop (e.g. while()
).
function loop() {
if (isPlaying) {
jet1.draw();
drawAllEnemies();
if (game != 1) {
requestAnimFrame(loop);
}
}
}
Or alternatively you could simply skip the second if
condition and change the first condition to if (isPlaying && game !== 1)
. You would have to make a variable called game and give it a value of 0. Add 1 to it every game.
The following can be used to get the date:
function date_date() {
var date = new Date();
var year = date.getYear();
var month = date.getMonth() + 1; if(month.toString().length==1){var month =
'0'+month;}
var day = date.getDate(); if(day.toString().length==1){var day = '0'+day;}
var hour = date.getHours(); if(hour.toString().length==1){var hour = '0'+hour;}
var minu = date.getMinutes(); if(minu.toString().length==1){var minu = '0'+minu;}
var seco = date.getSeconds(); if(seco.toString().length==1){var seco = '0'+seco;}
var date = year+'·'+month+'·'+day+'·'+hour+'·'+minu+'·'+seco;
Logger.log(date);
}
As of TypeScript 3.7 (https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html), you can now use the ?.
operator to get undefined when accessing an attribute (or calling a method) on a null or undefined object:
inputEl?.current?.focus(); // skips the call when inputEl or inputEl.current is null or undefined
For OAuth 2 passwords:
$bcrypt = new \Zend\Crypt\Password\Bcrypt;

When you create a stored function, you must declare either that it is deterministic or that it does not modify data. Otherwise, it may be unsafe for data recovery or replication.
By default, for a CREATE FUNCTION statement to be accepted, at least one of DETERMINISTIC, NO SQL, or READS SQL DATA must be specified explicitly. Otherwise an error occurs:
To fix this issue add following lines After Return and Before Begin statement:
READS SQL DATA
DETERMINISTIC
For Example :
CREATE FUNCTION f2()
RETURNS CHAR(36) CHARACTER SET utf8
/*ADD HERE */
READS SQL DATA
DETERMINISTIC

Docker really needs to implement this as a new feature, but here's another workaround option for situations in which you have an Entrypoint that terminates after success or failure, which can make it difficult to debug.
If you don't already have an Entrypoint script, create one that runs whatever command(s) you need for your container. Then, at the top of this file, add these lines to entrypoint.sh
:
# Run once, hold otherwise
if [ -f "already_ran" ]; then
echo "Already ran the Entrypoint once. Holding indefinitely for debugging."
cat
fi
touch already_ran
# Do your main things down here
To ensure that cat
holds the connection, you may need to provide a TTY. I'm running the container with my Entrypoint script like so:
docker run -t --entrypoint entrypoint.sh image_name
This will cause the script to run once, creating a file that indicates it has already run (in the container's virtual filesystem). You can then restart the container to perform debugging:
docker start container_name
When you restart the container, the already_ran
file will be found, causing the Entrypoint script to stall with cat
(which just waits forever for input that will never come, but keeps the container alive). You can then execute a debugging bash
session:
docker exec -i container_name bash
While the container is running, you can also remove already_ran
and manually execute the entrypoint.sh
script to rerun it, if you need to debug that way.
There are different regex engines but I think most of them will work with this:
apple|banana
I don't have an answer, but I do have an alternative.
If you use Fiddler2 to monitor traffic AND enable HTTPS Decryption, your development environment will not complain. This will not work on WinRT devices, such as Microsoft Surface, because you cannot install standard apps on them. But your development Win8 computer will be fine.
To enable HTTPS encryption in Fiddler2, go to Tools > Fiddler Options > HTTPS (Tab) > Check "Decrypt HTTPS Traffic".
I'm going to keep my eye on this thread hoping for someone to have an elegant solution.

After I have tried lot of workaround for this issue.. I thought this out and it works fine.
Spring works in standalone application. You are using the wrong way to create a spring bean. The correct way to do it like this:
@Component
public class Main {
public static void main(String[] args) {
ApplicationContext context =
new ClassPathXmlApplicationContext("META-INF/config.xml");
Main p = context.getBean(Main.class);
p.start(args);
}
@Autowired
private MyBean myBean;
private void start(String[] args) {
System.out.println("my beans method: " + myBean.getStr());
}
}
@Service
public class MyBean {
public String getStr() {
return "string";
}
}
In the first case (the one in the question), you are creating the object by yourself, rather than getting it from the Spring context. So Spring does not get a chance to Autowire
the dependencies (which causes the NullPointerException
).
In the second case (the one in this answer), you get the bean from the Spring context and hence it is Spring managed and Spring takes care of autowiring
.
Fragments lives within the Activity and has:
Think of Fragments as a sub activity of the main activity it belongs to, it cannot exist of its own and it can be called/reused again and again. Hope this helps :)
As stated in a comment at
with System.Net.Mail, use port 25 instead of 465:
You must set SSL=true and Port=25. Server responds to your request from unprotected 25 and then throws connection to protected 465.
You can catch it like any other exception:
try {
foo();
}
catch (const std::bad_alloc&) {
return -1;
}
Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.
In general you cannot, and should not try, to respond to this error. bad_alloc
indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.
Worse, modern operating systems often over-allocate: on such systems, malloc
and new
can return a valid pointer even if there is not enough free memory left – std::bad_alloc
will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).
The only thing you could do when catching std::bad_alloc
is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).
In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:
It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.1
OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:
lru_cache<widget> widget_cache;
double perform_operation(int widget_id) {
std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
if (not maybe_widget) {
maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
}
return maybe_widget->frobnicate();
}
…
for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
try {
return perform_operation(widget_id);
} catch (std::bad_alloc const&) {
if (widget_cache.empty()) throw; // memory error elsewhere.
widget_cache.remove_oldest();
}
}
// Handle too many failed attempts here.
But even here, using std::set_new_handler
instead of handling std::bad_alloc
provides the same benefit and would be much simpler.
1 If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.
new
in c++?The usual notion is that if new
operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc
.
However, something more happens even before a bad_alloc
exception is thrown:
C++03 Section 3.7.4.1.3: says
An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.
Consider the following code sample:
#include <iostream>
#include <cstdlib>
// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
std::cerr << "Unable to satisfy request for memory\n";
std::abort();
}
int main()
{
//set the new_handler
std::set_new_handler(outOfMemHandler);
//Request huge memory size, that will cause ::operator new to fail
int *pBigDataArray = new int[100000000L];
return 0;
}
In the above example, operator new
(most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler()
will be called, and the program will abort after issuing an error message.
As seen here the default behavior of new
operator when unable to fulfill a memory request, is to call the new-handler
function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort()
, outOfMemHandler()
would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.
new_handler
and set_new_handler
?new_handler
is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler
is a function that takes and returns a new_handler
.
Something like:
typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();
set_new_handler's parameter is a pointer to the function operator new
should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.
Given the behavior of new
a well designed user program should handle out of memory conditions by providing a proper new_handler
which does one of the following:
Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.
Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler
). The next time operator new calls the new-handler function, it will get the one most recently installed.
(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)
Uninstall the new-handler: This is done by passing a null pointer to set_new_handler
. With no new-handler installed, operator new
will throw an exception ((convertible to) std::bad_alloc
) when memory allocation is unsuccessful.
Throw an exception convertible to std::bad_alloc
. Such exceptions are not be caught by operator new
, but will propagate to the site originating the request for memory.
Not return: By calling abort
or exit
.
When you call ScriptManager.RegisterStartupScript, the "Control" parameter must be a control that is within an UpdatePanel that will be updated. You need to change it to:
ScriptManager.RegisterStartupScript(this, this.GetType(), Guid.NewGuid().ToString(), script, true);
Here's a simplest example from ASP.NET Community, this gave me a clear understanding on the concept....
what difference does this make?
For an example of this, here is a way to put focus on a text box on a page when the page is loaded into the browser—with Visual Basic using the RegisterStartupScript
method:
Page.ClientScript.RegisterStartupScript(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)
This works well because the textbox on the page is generated and placed on the page by the time the browser gets down to the bottom of the page and gets to this little bit of JavaScript.
But, if instead it was written like this (using the RegisterClientScriptBlock
method):
Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)
Focus will not get to the textbox control and a JavaScript error will be generated on the page
The reason for this is that the browser will encounter the JavaScript before the text box is on the page. Therefore, the JavaScript will not be able to find a TextBox1.
I would like to explain a bit what happens behind the scenes.
Dataframes are a set of Series.
Series in turn are an extension of a numpy.array
.
numpy.array
s have a property .name
.
This is the name of the series. It is seldom that Pandas respects this attribute, but it lingers in places and can be used to hack some Pandas behaviors.
A lot of answers here talks about the df.columns
attribute being a list
when in fact it is a Series
. This means it has a .name
attribute.
This is what happens if you decide to fill in the name of the columns Series
:
df.columns = ['column_one', 'column_two']
df.columns.names = ['name of the list of columns']
df.index.names = ['name of the index']
name of the list of columns column_one column_two
name of the index
0 4 1
1 5 2
2 6 3
Note that the name of the index always comes one column lower.
The .name
attribute lingers on sometimes. If you set df.columns = ['one', 'two']
then the df.one.name
will be 'one'
.
If you set df.one.name = 'three'
then df.columns
will still give you ['one', 'two']
, and df.one.name
will give you 'three'
.
pd.DataFrame(df.one)
will return
three
0 1
1 2
2 3
Because Pandas reuses the .name
of the already defined Series
.
Pandas has ways of doing multi-layered column names. There is not so much magic involved, but I wanted to cover this in my answer too since I don't see anyone picking up on this here.
|one |
|one |two |
0 | 4 | 1 |
1 | 5 | 2 |
2 | 6 | 3 |
This is easily achievable by setting columns to lists, like this:
df.columns = [['one', 'one'], ['one', 'two']]
write a button tag and on click function
var x = document.getElementById('codeRefer').innerHTML;
document.getElementById('codeRefer').innerHTML = x;
write this all in onclick function
actually you don't need to replace this all....
there are 2 ways to do this. One is to use autoclose property, the other (alternativ) way is to use the on change property thats fired by the input when selecting a Date.
HTML
<div class="container">
<div class="hero-unit">
<input type="text" placeholder="Sample 1: Click to show datepicker" id="example1">
</div>
<div class="hero-unit">
<input type="text" placeholder="Sample 2: Click to show datepicker" id="example2">
</div>
</div>
jQuery
$(document).ready(function () {
$('#example1').datepicker({
format: "dd/mm/yyyy",
autoclose: true
});
//Alternativ way
$('#example2').datepicker({
format: "dd/mm/yyyy"
}).on('change', function(){
$('.datepicker').hide();
});
});
this is all you have to do :)
HERE IS A FIDDLE to see whats happening.
Fiddleupdate on 13 of July 2016: CDN wasnt present anymore
According to your EDIT:
$('#example1').datepicker().on('changeDate', function (ev) {
$('#example1').Close();
});
Here you take the Input (that has no Close-Function) and create a Datepicker-Element. If the element changes you want to close it but you still try to close the Input (That has no close-function).
Binding a mouseup event to the document state may not be the best idea because you will fire all containing scripts on each click!
Thats it :)

It is not possible to find the number of elements in an array unless it is a character array. Consider the below example:
int main()
{
int arr[100]={1,2,3,4,5};
int size = sizeof(arr)/sizeof(arr[0]);
printf("%d", size);
return 1;
}
The above value gives us value 100 even if the number of elements is five. If it is a character array, you can search linearly for the null string at the end of the array and increase the counter as you go through.
From inside your Symfony project, you can get the value in PHP this way:
$symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;
if(isnull({uspRptMonthlyGasRevenueByGas;1.YearTotal})) = true then
"nd"
else
totext({uspRptMonthlyGasRevenueByGas;1.YearTotal},'###.00')
The above logic should be what you are looking for.
You will need to specify TimeSeries in Excel to be plotted. Have a look at this
Consider using a Spinner instead of a Number Picker in a Dialog. It's not exactly what was asked for, but it's much easier to implement, more contextual UI design, and should fulfill most use cases. The equivalent code for a Spinner is:
Spinner picker = new Spinner(this);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_item, yourStringList);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
picker.setAdapter(adapter);
It was changed between 3.1 and 3.2:
This is a terse description of the new features added to bash-3.2 since the release of bash-3.1.
Quoting the string argument to the [[ command's =~ operator now forces string matching, as with the other pattern-matching operators.
So use it without the quotes thus:
i="test"
if [[ $i =~ 200[78] ]] ; then
echo "OK"
else
echo "not OK"
fi
index.html
should be inside templates
, as I know. So, your second attempt looks correct.
But, as the error message says, index.html
looks like having some errors. E.g. the in the third line, the meta
tag should be actually head
tag, I think.
Incase you are not able to resolve the issue in any other way, then try this(it worked for me!):
Keep this below code into your web config file then rename value="yourwebformname.aspx"
<system.webServer>
<defaultDocument>
<files>
<add value="insertion.aspx" />
</files>
</defaultDocument>
<directoryBrowse enabled="false" />
</system.webServer>
else Try:
<system.webServer>
<directoryBrowse enabled="true" />
</system.webServer>
Starting with CMake 3.15, the correct way of achieving this would be using:
cmake --install <dir> --prefix "/usr"
If you want to retrieve the key's value if it exists, you can also use
try:
value = a[key]
except KeyError:
# Key is not present
pass
If you want to retrieve a default value when the key does not exist, use
value = a.get(key, default_value)
.
If you want to set the default value at the same time in case the key does not exist, use
value = a.setdefault(key, default_value)
.
When writing CMake scripts there is a lot you need to know about the syntax and how to use variables in CMake.
Strings using set()
:
set(MyString "Some Text")
set(MyStringWithVar "Some other Text: ${MyString}")
set(MyStringWithQuot "Some quote: \"${MyStringWithVar}\"")
Or with string()
:
string(APPEND MyStringWithContent " ${MyString}")
Lists using set()
:
set(MyList "a" "b" "c")
set(MyList ${MyList} "d")
Or better with list()
:
list(APPEND MyList "a" "b" "c")
list(APPEND MyList "d")
Lists of File Names:
set(MySourcesList "File.name" "File with Space.name")
list(APPEND MySourcesList "File.name" "File with Space.name")
add_excutable(MyExeTarget ${MySourcesList})
set()
Commandstring()
Commandlist()
CommandFirst there are the "Normal Variables" and things you need to know about their scope:
CMakeLists.txt
they are set in and everything called from there (add_subdirectory()
, include()
, macro()
and function()
).add_subdirectory()
and function()
commands are special, because they open-up their own scope.
set(...)
there are only visible there and they make a copy of all normal variables of the scope level they are called from (called parent scope).set(... PARENT_SCOPE)
function(xyz _resultVar)
is setting set(${_resultVar} 1 PARENT_SCOPE)
include()
or macro()
scripts will modify variables directly in the scope of where they are called from. Second there is the "Global Variables Cache". Things you need to know about the Cache:
CMakeCache.txt
file in your binary output directory.The values in the Cache can be modified in CMake's GUI application before they are generated. Therefore they - in comparison to normal variables - have a type
and a docstring
. I normally don't use the GUI so I use set(... CACHE INTERNAL "")
to set my global and persistant values.
Please note that the INTERNAL
cache variable type does imply FORCE
In a CMake script you can only change existing Cache entries if you use the set(... CACHE ... FORCE)
syntax. This behavior is made use of e.g. by CMake itself, because it normally does not force Cache entries itself and therefore you can pre-define it with another value.
cmake -D var:type=value
, just cmake -D var=value
or with cmake -C CMakeInitialCache.cmake
.unset(... CACHE)
.The Cache is global and you can set them virtually anywhere in your CMake scripts. But I would recommend you think twice about where to use Cache variables (they are global and they are persistant). I normally prefer the set_property(GLOBAL PROPERTY ...)
and set_property(GLOBAL APPEND PROPERTY ...)
syntax to define my own non-persistant global variables.
To avoid pitfalls you should know the following about variables:
find_...
commands - if successful - do write their results as cached variables "so that no call will search again"set(MyVar a b c)
is "a;b;c"
and set(MyVar "a b c")
is "a b c"
list()
command for handling listsfunctions()
instead of macros()
because you don't want your local variables to show up in the parent scope. project()
and enable_language()
calls. So it could get important to set some variables before those commands are used.Sometimes only debugging variables helps. The following may help you:
printf
debugging style by using the message()
command. There also some ready to use modules shipped with CMake itself: CMakePrintHelpers.cmake, CMakePrintSystemInformation.cmakeCMakeCache.txt
file in your binary output directory. This file is even generated if the actual generation of your make environment fails.cmake --trace ...
to see the CMake's complete parsing process. That's sort of the last reserve, because it generates a lot of output.$ENV{...}
and write set(ENV{...} ...)
environment variables$<...>
are only evaluated when CMake's generator writes the make environment (it comparison to normal variables that are replaced "in-place" by the parser)${${...}}
you can give variable names in a variable and reference its content.if()
command)
if(MyVariable)
you can directly check a variable for true/false (no need here for the enclosing ${...}
)1
, ON
, YES
, TRUE
, Y
, or a non-zero number. 0
, OFF
, NO
, FALSE
, N
, IGNORE
, NOTFOUND
, the empty string, or ends in the suffix -NOTFOUND
.if(MSVC)
, but it can be confusing for someone who does not know this syntax shortcut.set(CMAKE_${lang}_COMPILER ...)
if()
commands. Here is an example where CMAKE_CXX_COMPILER_ID
is "MSVC"
and MSVC
is "1"
:
if("${CMAKE_CXX_COMPILER_ID}" STREQUAL "MSVC")
is true, because it evaluates to if("1" STREQUAL "1")
if(CMAKE_CXX_COMPILER_ID STREQUAL "MSVC")
is false, because it evaluates to if("MSVC" STREQUAL "1")
if(MSVC)
cmake_policy(SET CMP0054 NEW)
to "only interpret if()
arguments as variables or keywords when unquoted."option()
command
ON
or OFF
and they allow some special handling like e.g. dependenciesoption
with the set
command. The value given to option
is really only the "initial value" (transferred once to the cache during the first configuration step) and is afterwards meant to be changed by the user through CMake's GUI.Scenario 1: If you want to undo the last commit say 8123b7e04b3, below is the command(this worked for me):
git push origin +8123b7e04b3^:<branch_name>
Output looks like below:
Total 0 (delta 0), reused 0 (delta 0)
To https://testlocation/code.git
+ 8123b7e...92bc500 8123b7e04b3^ -> master (forced update)
Note: To update the change to your local code (to remove the commit locally as well) :
$ git reset --hard origin/<branchName>
Message displayed is : HEAD is now at 8a3902a comments_entered_for_commit
Additional info: Scenario 2: In some situation, you may want to revert back what you just undo'ed (basically undo the undo) through the previous command, then use the below command:
git reset --hard 8123b7e04b3
Output:
HEAD is now at cc6206c Comment_that_was_entered_for_commit

To me, Fresco is the best among the other libraries.
Just setup Fresco and then simply set the imageURI like this:
draweeView.setImageURI(uri);
Check out this answer explaining some of Fresco benefits.
I use this simple function for JQuery based project
var pointerEventToXY = function(e){
var out = {x:0, y:0};
if(e.type == 'touchstart' || e.type == 'touchmove' || e.type == 'touchend' || e.type == 'touchcancel'){
var touch = e.originalEvent.touches[0] || e.originalEvent.changedTouches[0];
out.x = touch.pageX;
out.y = touch.pageY;
} else if (e.type == 'mousedown' || e.type == 'mouseup' || e.type == 'mousemove' || e.type == 'mouseover'|| e.type=='mouseout' || e.type=='mouseenter' || e.type=='mouseleave') {
out.x = e.pageX;
out.y = e.pageY;
}
return out;
};
example:
$('a').on('mousedown touchstart', function(e){
console.log(pointerEventToXY(e)); // will return obj ..kind of {x:20,y:40}
})
hope this will be usefull for you ;)
There should be one - and preferably only one - obvious way to do it.
Therefore list(dictionary.values())
is the one way.

This way you can specifically call it outside of the for loop.
You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.
You should be doing something more like this:
class MyClassTest
{
[TestMethod]
public void MyMethodTest()
{
string action = "test";
Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();
mockSomeClass.Setup(mock => mock.DoSomething());
MyClass myClass = new MyClass(mockSomeClass.Object);
myClass.MyMethod(action);
// Explicitly verify each expectation...
mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());
// ...or verify everything.
// mockSomeClass.VerifyAll();
}
}
In other words, you are verifying that calling MyClass#MyMethod
, your class will definitely call SomeClass#DoSomething
once in that process. Note that you don't need the Times
argument; I was just demonstrating its value.

My approach is similar to what bpedit shows above, but with an iOS 9+ focus. I wanted to change the scope of the FSCalendar when the view rotates.
override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
super.viewWillTransitionToSize(size, withTransitionCoordinator: coordinator)
coordinator.animateAlongsideTransition({ (context) in
if size.height < size.width {
self.calendar.setScope(.Week, animated: true)
self.calendar.appearance.cellShape = .Rectangle
}
else {
self.calendar.appearance.cellShape = .Circle
self.calendar.setScope(.Month, animated: true)
}
}, completion: nil)
}
This below worked, but I felt sheepish about it :)
coordinator.animateAlongsideTransition({ (context) in
if size.height < size.width {
self.calendar.scope = .Week
self.calendar.appearance.cellShape = .Rectangle
}
}) { (context) in
if size.height > size.width {
self.calendar.scope = .Month
self.calendar.appearance.cellShape = .Circle
}
}
Ask yourself the opposite question: How can I determine if two rectangles do not intersect at all? Obviously, a rectangle A completely to the left of rectangle B does not intersect. Also if A is completely to the right. And similarly if A is completely above B or completely below B. In any other case A and B intersect.
What follows may have bugs, but I am pretty confident about the algorithm:
struct Rectangle { int x; int y; int width; int height; };
bool is_left_of(Rectangle const & a, Rectangle const & b) {
if (a.x + a.width <= b.x) return true;
return false;
}
bool is_right_of(Rectangle const & a, Rectangle const & b) {
return is_left_of(b, a);
}
bool not_intersect( Rectangle const & a, Rectangle const & b) {
if (is_left_of(a, b)) return true;
if (is_right_of(a, b)) return true;
// Do the same for top/bottom...
}
bool intersect(Rectangle const & a, Rectangle const & b) {
return !not_intersect(a, b);
}
rm -rf *
Would remove everything (folders & files) in the current directory.
But be careful! Only execute this command if you are absolutely sure, that you are in the right directory.

The solution provided by Barry above is excellent, but there's is the "flicker-problem".
As soon as the Value is above zero the OnPaint will be envoked repeatedly and the text will flicker.
There is a solution to this. We do not need VisualStyles for the object since we will be drawing it with our own code.
Add the following code to the custom object Barry wrote and you will avoid the flicker:
[DllImportAttribute("uxtheme.dll")]
private static extern int SetWindowTheme(IntPtr hWnd, string appname, string idlist);
protected override void OnHandleCreated(EventArgs e)
{
SetWindowTheme(this.Handle, "", "");
base.OnHandleCreated(e);
}
I did not write this myself. It found it here: https://stackoverflow.com/a/299983/1163954
I've testet it and it works.
If anyone comes here after me, this is the answer that worked for me.
NOTE: please make to read the comments before using this, this not complete. The best advice for update queries I can give is to switch to SqlServer ;)
update mytable t
set z = (
with comp as (
select b.*, 42 as computed
from mytable t
where bs_id = 1
)
select c.computed
from comp c
where c.id = t.id
)
Good luck,
GJ
Once Data is exported to excel, highlight the date column and format to fit your needs or use the custom field. Worked for me like a charm!
re.Match
objects have a number of methods to help you with this:

Check this query in Athena for only one-space separated string (e.g. first name and middle name combination):
SELECT name, REVERSE( SUBSTR( REVERSE(name), 1, STRPOS(REVERSE(name), ' ') ) ) AS middle_name
FROM name_table
If you expect to have two or more spaces, you can easily extend the above query.
This might be too late but if you add
worksheet.Columns.AutoFit();
or
worksheet.Rows.AutoFit();
it also works.
This is not an answer to the question, but I couldn't figure out how to get decent code formatting in a comment above... so auto-down-reputation-be-damned here's my comment.
I have the recipe submtted by @Dobes in a fancy shmancy [alias] entry in my .gitconfig:
# to untrack a local branch when I can't remember 'git config --unset'
cbr = "!f(){ git symbolic-ref -q HEAD 2>/dev/null | sed -e 's|refs/heads/||'; }; f"
bruntrack = "!f(){ br=${1:-`git cbr`}; \
rm=`git config --get branch.$br.remote`; \
tr=`git config --get branch.$br.merge`; \
[ $rm:$tr = : ] && echo \"# untrack: not a tracking branch: $br\" && return 1; \
git config --unset branch.$br.remote; git config --unset branch.$br.merge; \
echo \"# untrack: branch $br no longer tracking $rm:$tr\"; return 0; }; f"
Then I can just run
$ git bruntrack branchname
@Alan's answer will do what you're looking for, but this solution fails when you use the responsive capabilities of Bootstrap. In your case, you're using the xs
sizes so you won't notice, but if you used anything else (e.g. col-sm
, col-md
, etc), you'd understand.
Another approach is to play with margins and padding. See the updated fiddle: http://jsfiddle.net/jz8j247x/1/
.left-side {
background-color: blue;
padding-bottom: 1000px;
margin-bottom: -1000px;
height: 100%;
}
.something {
height: 100%;
background-color: red;
padding-bottom: 1000px;
margin-bottom: -1000px;
height: 100%;
}
.row {
background-color: green;
overflow: hidden;
}
There are better answers here, but how I fix this may be relevant for someone:
After checking out the project from SVN, instead of choosing the 1.7 version, I chose Subversion 1.6 and it worked.
width:200px;
white-space: nowrap;
text-overflow: ellipsis;
overflow: hidden;
Define width also to set overflow in one line

If you just do eval $cmd
when we do cmd="ls -l"
(interactively and in a script) we get the desired result. In your case, you have a pipe with a grep without a pattern, so the grep part will fail with an error message. Just $cmd
will generate a "command not found" (or some such) message.
So try use eval and use a finished command, not one that generates an error message.
It's all about the key bindings which one can simply achieve from .vimrc configurations.
As far as clipboard is concerned you can use :set clipboard unnamed
and the yank from vim will go to system clipboard.
Anyways, whichever one you end up using I suggest using this vimrc config
, it contains a whole lot of plugins and bindings which will make your experience smooth.
Try using the @

<template>

</template>
<style scoped src="@/assets/styles/mystyles.css">

sigma = sum(y*(x - mean)**2)
should be
sigma = np.sqrt(sum(y*(x - mean)**2))
I usually use numpy sum over the logical condition column:
>>> import numpy as np
>>> import pandas as pd
>>> df = pd.DataFrame({'Age' : [20,24,18,5,78]})
>>> np.sum(df['Age'] > 20)

This seems to me slightly shorter than the solution presented above
Select * is a SQL antipattern. It should not be used in production code for many reasons including:
It takes a tiny bit longer to process. When things are run millions of times, those tiny bits can matter. A slow database where the slowness is caused by this type of sloppy coding throughout is the hardest kind to performance tune.
It means you are probably sending more data than you need which causes both server and network bottlenecks. If you have an inner join, the chances of sending more data than you need are 100%.
It causes maintenance problems especially when you have added new columns that you do not want seen everywhere. Further if you have a new column, you may need to do something to the interface to determine what to do with that column.
It can break views (I know this is true in SQl server, it may or may not be true in mysql).
If someone is silly enough to rebuild the tables with the columns in a differnt order (which you shouldn't do but it happens all teh time), all sorts of code can break. Espcially code for an insert for example where suddenly you are putting the city into the address_3 field becasue without specifying, the database can only go on the order of the columns. This is bad enough when the data types change but worse when the swapped columns have the same datatype becasue you can go for sometime inserting bad data that is a mess to clean up. You need to care about data integrity.
If it is used in an insert, it will break the insert if a new column is added in one table but not the other.
It might break triggers. Trigger problems can be difficult to diagnose.
Add up all this against the time it take to add in the column names (heck you may even have an interface that allows you to drag over the columns names (I know I do in SQL Server, I'd bet there is some way to do this is some tool you use to write mysql queries.) Let's see, "I can cause maintenance problems, I can cause performance problems and I can cause data integrity problems, but hey I saved five minutes of dev time." Really just put in the specific columns you want.
I also suggest you read this book: http://www.amazon.com/SQL-Antipatterns-Programming-Pragmatic-Programmers-ebook/dp/B00A376BB2/ref=sr_1_1?s=digital-text&ie=UTF8&qid=1389896688&sr=1-1&keywords=sql+antipatterns
As of Gradle 4.9 Application plugin understands --args
option, so passing the arguments is as simple as:
build.gradle
plugins {
id 'application'
}
mainClassName = "my.App"
src/main/java/my/App.java
public class App {
public static void main(String[] args) {
System.out.println(args);
}
}
bash
./gradlew run --args='This string will be passed into my.App#main arguments'
or in Windows, use double quotes:
gradlew run --args="This string will be passed into my.App#main arguments"
So at first I was tempted to return my application error with 200 OK and a specific XML payload (ie. Pay us more and you'll get the storage you need!) but I stopped to think about it and it seems to soapy (/shrug in horror).
I wouldn't return a 200 unless there really was nothing wrong with the request. From RFC2616, 200 means "the request has succeeded."
If the client's storage quota has been exceeded (for whatever reason), I'd return a 403 (Forbidden):
The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead.
This tells the client that the request was OK, but that it failed (something a 200 doesn't do). This also gives you the opportunity to explain the problem (and its solution) in the response body.
What other specific error conditions did you have in mind?
Patrick is correct, both in the use of the xsl:if
, and in the syntax for checking for the existence of a node. However, as Patrick's response implies, there is no xsl equivalent to if-then-else, so if you are looking for something more like an if-then-else, you're normally better off using xsl:choose
and xsl:otherwise
. So, Patrick's example syntax will work, but this is an alternative:
<xsl:choose>
<xsl:when test="/html/body">body node exists</xsl:when>
<xsl:otherwise>body node missing</xsl:otherwise>
</xsl:choose>
It seems that using the id works as well as the index, e.g. simply doing this will work out of the box...
$("#tabs").tabs("select", "#sample-tab-1");
This is well documented in the official docs:
"Select a tab, as if it were clicked. The second argument is the zero-based index of the tab to be selected or the id selector of the panel the tab is associated with (the tab's href fragment identifier, e.g. hash, points to the panel's id)."
I assume this was added after this question was asked and probably after most of the answers
I liked the http://ipify.org. They even provide Python code for using their API.
# This example requires the requests library be installed. You can learn more
# about the Requests library here: http://docs.python-requests.org/en/latest/
from requests import get
ip = get('https://api.ipify.org').text
print('My public IP address is: {}'.format(ip))
As id is PK it MUST be unique and not null. If you do not mention any field in the fields list for insert it'll be supposed to be null or default value. Set identity (i.e. autoincrement) for this field if you do not want to set it manualy every time.
Integers are only 32 bits. This means that its max value is 2^31 -1
. As you see, for very small numbers, you quickly have a result which can't be represented by an integer anymore. That's why Math.pow
uses double
.
If you want arbitrary integer precision, use BigInteger.pow
. But it's of course less efficient.
This stems from the fact that on deletion, the iteration skips one element as it semms only to work on the index.
Workaround could be:
x = ["ok", "jj", "uy", "poooo", "fren"]
for item in x[:]: # make a copy of x
if len(item) != 2:
print "length of %s is: %s" %(item, len(item))
x.remove(item)
This worked for me best
NSString *name = [[UIDevice currentDevice] name];
if ([name isEqualToString:@"iPhone Simulator"]) {
}
ANDROID_HOME, which also points to the SDK installation directory, is deprecated. If you continue to use it, the following rules apply: If ANDROID_HOME is defined and contains a valid SDK installation, its value is used instead of the value in ANDROID_SDK_ROOT. If ANDROID_HOME is not defined, the value in ANDROID_SDK_ROOT is used. If ANDROID_HOME is defined but does not exist or does not contain a valid SDK installation, the value in ANDROID_SDK_ROOT is used instead.
For most of the time, I use decimal(9,2) which takes the least storage (5 bytes) in sql decimal type.
Precision => Storage bytes
It can store from 0 up to 9 999 999.99 (7 digit infront + 2 digit behind decimal point = total 9 digit), which is big enough for most of the values.

I find it very useful to append both stdout and stderr to a log file. I was glad to see a solution by alfonx with exec > >(tee -a)
, because I was wondering how to accomplish this using exec
. I came across a creative solution using here-doc syntax and .
: https://unix.stackexchange.com/questions/80707/how-to-output-text-to-both-screen-and-file-inside-a-shell-script
I discovered that in zsh, the here-doc solution can be modified using the "multios" construct to copy output to both stdout/stderr and the log file:
#!/bin/zsh
LOG=$0.log
# 8 is an arbitrary number;
# multiple redirects for the same file descriptor
# triggers "multios"
. 8<<\EOF /dev/fd/8 2>&2 >&1 2>>$LOG >>$LOG
# some commands
date >&2
set -x
echo hi
echo bye
EOF
echo not logged
It is not as readable as the exec
solution but it has the advantage of allowing you to log just part of the script. Of course, if you omit the EOF then the whole script is executed with logging. I'm not sure how zsh
implements multios, but it may have less overhead than tee
. Unfortunately it seems that one cannot use multios with exec
.
You can also use listView.setOnItemLongClickListener to delete selected item. Below is the code.
// listView = name of your ListView
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int
position, long id) {
// it will get the position of selected item from the ListView
final int selected_item = position;
new AlertDialog.Builder(MainActivity.this).
setIcon(android.R.drawable.ic_delete)
.setTitle("Are you sure...")
.setMessage("Do you want to delete the selected item..?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which)
{
list.remove(selected_item);
arrayAdapter.notifyDataSetChanged();
}
})
.setNegativeButton("No" , null).show();
return true;
}
});

You cannot do new T()
due to type erasure. The default constructor can only be
public Navigation() { this("", "", null); }
You can create other constructors to provide default values for trigger and description. You need an concrete object of T

After using the wrong quotation mark characters in install.packages()

Moment.js stores dates it utc and can apply different timezones to it. By default it applies your local timezone. If you want to set time on utc date time you need to specify utc timezone.
Try the following code:

m.toISOString()
m.format()

it gives to the carousel an interval of 8 seconds
Put a space between the "-->" of your header comments. e.g. "- ->"
Check Empty object
$scope.isValid = function(value) {
return !value
}
I did it like this:
$missing = array();
foreach ($_POST as $key => $value) { if ($value == "") { array_push($missing, $key);}}
if (count($missing) > 0) {
echo "Required fields found empty: ";
foreach ($missing as $k => $v) { echo $v." ";}
} else {
unset($missing);
// do your stuff here with the $_POST
}
For deleting a certain amount of characters before the cursor, you can use X. For deleting a certain number of words after the cursor, you can use dw (multiple words can be deleted using 3dw for 3 words for example). For deleting around the cursor in general, you can use daw.
How about programmatically modifying the size attribute on the input?
Semantically (imo), this solution is better than the accepted solution because it still uses input fields for user input but it does introduce a little bit of jQuery. Soundcloud does something similar to this for their tagging.
<input size="1" />
$('input').on('keydown', function(evt) {
var $this = $(this),
size = parseInt($this.attr('size'), 10),
isValidKey = (evt.which >= 65 && evt.which <= 90) || // a-zA-Z
(evt.which >= 48 && evt.which <= 57) || // 0-9
evt.which === 32;
if ( evt.which === 8 && size > 0 ) {
// backspace
$this.attr('size', size - 1);
} else if ( isValidKey ) {
// all other keystrokes
$this.attr('size', size + 1);
}
});
