If you're using WPF and the previous answers don't help, you can retrieve the result using:
var result = MessageBox.Show("Message", "caption", MessageBoxButton.YesNo, MessageBoxImage.Question);
if (result == MessageBoxResult.Yes)
{
// Do something
}

If you want to get the date and time in a specific pattern you can use
Date d = new Date();
CharSequence s = DateFormat.format("yyyy-MM-dd hh:mm:ss", d.getTime());
To get the list of stashes that are still in your repository, but not reachable any more:
git fsck --unreachable | grep commit | cut -d" " -f3 | xargs git log --merges --no-walk --grep=WIP
If you gave a title to your stash, replace "WIP" in -grep=WIP
at the end of the command with a part of your message, e.g. -grep=Tesselation
.
The command is grepping for "WIP" because the default commit message for a stash is in the form WIP on mybranch: [previous-commit-hash] Message of the previous commit.
var="a b c"
for i in $var
do
p=`echo -e "$p"'\n'$i`
done
echo "$p"
The solution was simply to protect the inserted newline with a "" during current iteration when variable substitution happens.
you might try this if you logged in with root:
mysqld --user=root
Have you tried using cat to combine the files?
cat 10MB.pdf 10MB.pdf > 20MB.pdf
That should result in a 20MB file.
cursor.execute(sql,array)
Only takes two arguments.
It will iterate the "array"-object and match ? in the sql-string.
(with sanity checks to avoid sql-injection)
For Eclipse Mars (I've just verified that) you to do this (assuming that C:\eclipseMarsEE is root folder of your Eclipse):
To remove migration (if you already migrated the migration)
rake db:migrate:down VERSION="20130417185845" #Your migration version
To remove Model
rails d model name #name => Your model name
I had a problem with setting locale programmatically with devices that has Android OS N and higher. For me the solution was writing this code in my base activity:
(if you don't have a base activity then you should make these changes in all of your activities)
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(updateBaseContextLocale(base));
}
private Context updateBaseContextLocale(Context context) {
String language = SharedPref.getInstance().getSavedLanguage();
Locale locale = new Locale(language);
Locale.setDefault(locale);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
return updateResourcesLocale(context, locale);
}
return updateResourcesLocaleLegacy(context, locale);
}
@TargetApi(Build.VERSION_CODES.N)
private Context updateResourcesLocale(Context context, Locale locale) {
Configuration configuration = context.getResources().getConfiguration();
configuration.setLocale(locale);
return context.createConfigurationContext(configuration);
}
@SuppressWarnings("deprecation")
private Context updateResourcesLocaleLegacy(Context context, Locale locale) {
Resources resources = context.getResources();
Configuration configuration = resources.getConfiguration();
configuration.locale = locale;
resources.updateConfiguration(configuration, resources.getDisplayMetrics());
return context;
}
note that here it is not enough to call
createConfigurationContext(configuration)
you also need to get the context that this method returns and then to set this context in the attachBaseContext
method.
Please use below trick:
On Linux/Unix, you can append files to the .gitignore file with the echo
command. For example if you want to ignore all .svn
folders, run this from the root of the project:
echo .svn/ >> .gitignore
I think another benefit of using the MVC pattern is that it opens up the doors to other approaches to the design, such as MVP/Presenter first and the many other MV* patterns.
Without this fundamental segregation of the design "components" the adoption of these techniques would be much more difficult.
I think it helps to make your code even more interface-based.. Not only within the individual project, but you can almost start to develop common "views" which mean you can template lot more of the "grunt" code used in your applications. For example, a very abstract "data view" which simply takes a bunch of data and throws it to a common grid layout.
If I remember correctly, this is a pretty good podcast on MV* patterns (listened to it a while ago!)
Post increment(a++)
If int b = a++,then this means
int b = a;
a = a+1;
Here we add 1 to the value. The value is returned before the increment is made,
For eg a = 1; b = a++;
Then b=1 and a=2
Pre-increment (++a)
If int b = ++a; then this means
a=a+1;
int b=a ;
Pre-increment: This will add 1 to the main value. The value will be returned after the increment is made, For a = 1; b = ++a; Then b=2 and a=2.

You can use ffprobe
:
ffprobe -i <file> -show_entries format=duration -v quiet -of csv="p=0"
It will output the duration in seconds, such as:
154.12
Adding the -sexagesimal
option will output duration as hours:minutes:seconds.microseconds:
00:02:34.12
empty
is an operator:
The
empty
operator is a prefix operation that can be used to determine whether a value is null or empty.

Maybe this is a bit late, but I want to add that there is a better way. Using UIView is simple, but relatively slow. This method overrides how the view draws itself and is faster:
- (void)drawRect:(CGRect)rect {
[super drawRect:rect];
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor);
// Draw them with a 2.0 stroke width so they are a bit more visible.
CGContextSetLineWidth(context, 2.0f);
CGContextMoveToPoint(context, 0.0f, 0.0f); //start at this point
CGContextAddLineToPoint(context, 20.0f, 20.0f); //draw to this point
// and now draw the Path!
CGContextStrokePath(context);
}
I found an easy way to do this without searching directories or log files:
kafka-dump-log --version
Output looks like this:
5.3.0-ccs (Commit:6481debc2be778ee)
And if you would like to use an existing context, rather than a new context which would be loaded from xml configuration by org.springframework.web.context.ContextLoaderListener, then see -> https://stackoverflow.com/a/40694787/3004747
In your code where you run the stored procedure you should have something like this:
SqlCommand c = new SqlCommand(...)
//...
Add such a line of code:
c.CommandTimeout = 0;
This will wait as much time as needed for the operation to complete.
You can write that for example:
private Date TruncarFecha(Date fechaParametro) throws ParseException {
String fecha="";
DateFormat outputFormatter = new SimpleDateFormat("MM/dd/yyyy");
fecha =outputFormatter.format(fechaParametro);
return outputFormatter.parse(fecha);
}
This is a slightly modified version of http://jdewit.github.io/bootstrap-timepicker/ which supports bootstrap 3. You can check it out here. https://github.com/m3wolf/bootstrap3-timepicker Let me know if it does not work and I will try to find an alternative.

i understood it by this:
function fun1() {
return this + 1;
}
function fun2(el) {
return el + 1;
}
var item = [5,4,3,2,1];
var newitem1 = $.each(item, fun1);
var newitem2 = $.map(item, fun2);
console.log(newitem1); // [5, 4, 3, 2, 1]
console.log(newitem2); // [6, 5, 4, 3, 2]
so, "each" function returns the original array while "map" function returns a new array
var value = CKEDITOR.instances['YourInstanceName'].getData()
alert( value);
Replace YourInstanceName
with the name of your instance and you will get the desired results.
When there is no concern about invalid string input or range issues, use the simplest: atoi()
Otherwise, the method with best error/range detection is neither atoi()
, nor sscanf()
.
This good answer all ready details the lack of error checking with atoi()
and some error checking with sscanf()
.
strtol()
is the most stringent function in converting a string to int
. Yet it is only a start. Below are detailed examples to show proper usage and so the reason for this answer after the accepted one.
// Over-simplified use
int strtoi(const char *nptr) {
int i = (int) strtol(nptr, (char **)NULL, 10);
return i;
}
This is the like atoi()
and neglects to use the error detection features of strtol()
.
To fully use strtol()
, there are various features to consider:
Detection of no conversion: Examples: "xyz"
, or ""
or "--0"
? In these cases, endptr
will match nptr
.
char *endptr;
int i = (int)strtol(nptr, &endptr, 10);
if (nptr == endptr) return FAIL_NO_CONVERT;
Should the whole string convert or just the leading portion: Is "123xyz"
OK?
char *endptr;
int i = (int)strtol(nptr, &endptr, 10);
if (*endptr != '\0') return FAIL_EXTRA_JUNK;
Detect if value was so big, the the result is not representable as a long
like "999999999999999999999999999999"
.
errno = 0;
long L = strtol(nptr, &endptr, 10);
if (errno == ERANGE) return FAIL_OVERFLOW;
Detect if the value was outside the range of than int
, but not long
. If int
and long
have the same range, this test is not needed.
long L = strtol(nptr, &endptr, 10);
if (L < INT_MIN || L > INT_MAX) return FAIL_INT_OVERFLOW;
Some implementations go beyond the C standard and set errno
for additional reasons such as errno to EINVAL in case no conversion was performed or EINVAL
The value of the Base parameter is not valid.. The best time to test for these errno
values is implementation dependent.
Putting this all together: (Adjust to your needs)
#include <errno.h>
#include <stdlib.h>
int strtoi(const char *nptr, int *error_code) {
char *endptr;
errno = 0;
long i = strtol(nptr, &endptr, 10);
#if LONG_MIN < INT_MIN || LONG_MAX > INT_MAX
if (errno == ERANGE || i > INT_MAX || i < INT_MIN) {
errno = ERANGE;
i = i > 0 : INT_MAX : INT_MIN;
*error_code = FAIL_INT_OVERFLOW;
}
#else
if (errno == ERANGE) {
*error_code = FAIL_OVERFLOW;
}
#endif
else if (endptr == nptr) {
*error_code = FAIL_NO_CONVERT;
} else if (*endptr != '\0') {
*error_code = FAIL_EXTRA_JUNK;
} else if (errno) {
*error_code = FAIL_IMPLEMENTATION_REASON;
}
return (int) i;
}
Note: All functions mentioned allow leading spaces, an optional leading sign character and are affected by locale change. Additional code is required for a more restrictive conversion.
Note: Non-OP title change skewed emphasis. This answer applies better to original title "convert string to integer sscanf or atoi"
The kernel is part of the operating system and closer to the hardware it provides low level services like:
An operating system also includes applications like the user interface (shell, gui, tools, and services).
If the Node
is not just any node, but actually an Element
(it could also be e.g. an attribute or a text node), you can cast it to Element
and use getElementsByTagName
.
Call next function like
byte[] m_Bytes = StreamHelper.ReadToEnd (mystream);
Function:
public static byte[] ReadToEnd(System.IO.Stream stream)
{
long originalPosition = 0;
if(stream.CanSeek)
{
originalPosition = stream.Position;
stream.Position = 0;
}
try
{
byte[] readBuffer = new byte[4096];
int totalBytesRead = 0;
int bytesRead;
while ((bytesRead = stream.Read(readBuffer, totalBytesRead, readBuffer.Length - totalBytesRead)) > 0)
{
totalBytesRead += bytesRead;
if (totalBytesRead == readBuffer.Length)
{
int nextByte = stream.ReadByte();
if (nextByte != -1)
{
byte[] temp = new byte[readBuffer.Length * 2];
Buffer.BlockCopy(readBuffer, 0, temp, 0, readBuffer.Length);
Buffer.SetByte(temp, totalBytesRead, (byte)nextByte);
readBuffer = temp;
totalBytesRead++;
}
}
}
byte[] buffer = readBuffer;
if (readBuffer.Length != totalBytesRead)
{
buffer = new byte[totalBytesRead];
Buffer.BlockCopy(readBuffer, 0, buffer, 0, totalBytesRead);
}
return buffer;
}
finally
{
if(stream.CanSeek)
{
stream.Position = originalPosition;
}
}
}

You should use Node.contains
, since it's now standard and available in all browsers.
https://developer.mozilla.org/en-US/docs/Web/API/Node.contains
Remove those char * ret
declarations inside if
blocks which hide outer ret
. Therefor you have memory leak and on the other hand un-allocated memory for ret
.
To compare a c-style string you should use strcmp(array,"")
not array!=""
. Your final code should looks like below:
char* appendCharToCharArray(char* array, char a)
{
size_t len = strlen(array);
char* ret = new char[len+2];
strcpy(ret, array);
ret[len] = a;
ret[len+1] = '\0';
return ret;
}
Note that, you must handle the allocated memory of returned ret
somewhere by delete[]
it.
Why you don't use std::string
? it has .append
method to append a character at the end of a string:
std::string str;
str.append('x');
// or
str += x;
java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;
That method was added in Servlet 2.5.
So this problem can have at least 3 causes:
web.xml
is not declared conform Servlet 2.5 or newer.To solve it,
web.xml
complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.servlet-api.jar
or j2ee.jar
in /WEB-INF/lib
or even worse, the JRE/lib
or JRE/lib/ext
. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.The accepted answer is problematic for http urls. Moreover Uri.LocalPath
does Windows specific conversions, and as someone pointed out leaves query strings in there. A better way is to use Uri.AbsolutePath
The correct way to do this for http urls is:
Uri uri = new Uri(hreflink);
string filename = System.IO.Path.GetFileName(uri.AbsolutePath);

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.
You've got:
//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]
Which translates into:
Get me all the elements that have an ID
that contains ctl00_btnAircraftMapCell
. Out of these elements, get any child elements that have a title
that contains Select Seat
.
What you actually want is:
//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]
Which translates into:
Get me all the anchor elements that have both: an id
that contains ctl00_btnAircraftMapCell
and a title
that contains Select Seat
.

To Add a folder, all the sub-directories, and files we can also Copy and Paste. For example we can:
Right click in Windows explorer on the folder, and Copy on the folder with many files and folders.
Then in Visual Studio Solution explorer, right click on the destination folder and click paste.
Optional add to TFS; Then in the top folder right click and check in to TFS to check in all sub-folders and files.

Codeigniter - dynamically getting relative/absolute path outside of application folder
Although it's not safest, but you can change in the source code. navigate to Python/2.7/site-packages/django/conf/urls/static.py
Then edit like following:
if settings.DEBUG or (prefix and '://' in prefix):
So then if settings.debug==False
it won't effect on the code, also after running try python manage.py runserver --runserver
to run static files.

I have a similar problem and I resolved in this way:
@RequestMapping(value = "{siteCode}/**/{fileName}.{fileExtension}")
public HttpEntity<byte[]> getResource(@PathVariable String siteCode,
@PathVariable String fileName, @PathVariable String fileExtension,
HttpServletRequest req, HttpServletResponse response ) throws IOException {
String fullPath = req.getPathInfo();
// Calling http://localhost:8080/SiteXX/images/argentine/flag.jpg
// fullPath conentent: /SiteXX/images/argentine/flag.jpg
}
Note that req.getPathInfo()
will return the complete path (with {siteCode}
and {fileName}.{fileExtension}
) so you will have to process conveniently.

There is a more effective way of generating an intersect, by using UNION ALL and GROUP BY. Performances are twice better according to my tests on large datasets.
Example:
SELECT t1.value from (
(SELECT DISTINCT value FROM table_a)
UNION ALL
(SELECT DISTINCT value FROM table_b)
) AS t1 GROUP BY value HAVING count(*) >= 2;
It is more effective, because with the INNER JOIN solution, MySQL will look up for the results of the first query, then for each row, look up for the result in the second query. With the UNION ALL-GROUP BY solution, it will query results of the first query, results of the second query, then group the results all together at once.
document.location is deprecated in favor of window.location, which can be accessed by just location, since it's a global object.

You can temporarily disable constraints on your tables, do work, then rebuild them.
Here is an easy way to do it...
Disable all indexes, including the primary keys, which will disable all foreign keys, then re-enable just the primary keys so you can work with them...
DECLARE @sql AS NVARCHAR(max)=''
select @sql = @sql +
'ALTER INDEX ALL ON [' + t.[name] + '] DISABLE;'+CHAR(13)
from
sys.tables t
where type='u'
select @sql = @sql +
'ALTER INDEX ' + i.[name] + ' ON [' + t.[name] + '] REBUILD;'+CHAR(13)
from
sys.key_constraints i
join
sys.tables t on i.parent_object_id=t.object_id
where
i.type='PK'
exec dbo.sp_executesql @sql;
go
[Do something, like loading data]
Then re-enable and rebuild the indexes...
DECLARE @sql AS NVARCHAR(max)=''
select @sql = @sql +
'ALTER INDEX ALL ON [' + t.[name] + '] REBUILD;'+CHAR(13)
from
sys.tables t

Layer draws out of clip region, you need to set it to mask to bounds:
self.mainImageView.layer.masksToBounds = true
From the docs:
By default, the corner radius does not apply to the image in the layer’s contents property; it applies only to the background color and border of the layer. However, setting the masksToBounds property to true causes the content to be clipped to the rounded corners

According to Wikipedia we know for sure: a file descriptor is a non-negative integer. The most important thing I think is missing, would be to say:
File descriptors are bound to a process ID.
We know most famous file descriptors are 0, 1 and 2.
0 corresponds to STDIN
, 1 to STDOUT
, and 2 to STDERR
.
Say, take shell processes as an example and how does it apply for it?
Check out this code
#>sleep 1000 &
[12] 14726
We created a process with the id 14726 (PID).
Using the lsof -p 14726
we can get the things like this:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
sleep 14726 root cwd DIR 8,1 4096 1201140 /home/x
sleep 14726 root rtd DIR 8,1 4096 2 /
sleep 14726 root txt REG 8,1 35000 786587 /bin/sleep
sleep 14726 root mem REG 8,1 11864720 1186503 /usr/lib/locale/locale-archive
sleep 14726 root mem REG 8,1 2030544 137184 /lib/x86_64-linux-gnu/libc-2.27.so
sleep 14726 root mem REG 8,1 170960 137156 /lib/x86_64-linux-gnu/ld-2.27.so
sleep 14726 root 0u CHR 136,6 0t0 9 /dev/pts/6
sleep 14726 root 1u CHR 136,6 0t0 9 /dev/pts/6
sleep 14726 root 2u CHR 136,6 0t0 9 /dev/pts/6
The 4-th column FD and the very next column TYPE correspond to the File Descriptor and the File Descriptor type.
Some of the values for the FD can be:
cwd – Current Working Directory
txt – Text file
mem – Memory mapped file
mmap – Memory mapped device
But the real file descriptor is under:
NUMBER – Represent the actual file descriptor.
The character after the number i.e "1u", represents the mode in which the file is opened. r for read, w for write, u for read and write.
TYPE specifies the type of the file. Some of the values of TYPEs are:
REG – Regular File
DIR – Directory
FIFO – First In First Out
But all file descriptors are CHR – Character special file (or character device file)
Now, we can identify the File Descriptors for STDIN
, STDOUT
and STDERR
easy with lsof -p PID
, or we can see the same if we ls /proc/PID/fd
.
Note also that file descriptor table that kernel keeps track of is not the same as files table or inodes table. These are separate, as some other answers explained.
You may ask yourself where are these file descriptors physically and what is stored in /dev/pts/6
for instance
sleep 14726 root 0u CHR 136,6 0t0 9 /dev/pts/6
sleep 14726 root 1u CHR 136,6 0t0 9 /dev/pts/6
sleep 14726 root 2u CHR 136,6 0t0 9 /dev/pts/6
Well, /dev/pts/6
lives purely in memory. These are not regular files, but so called character device files. You can check this with: ls -l /dev/pts/6
and they will start with c
, in my case crw--w----

Just to recall most Linux like OS define seven types of files:
Absolutely, yes you can. This link contains details about how you can achieve that: https://api.jquery.com/jquery.noconflict/.
Eric Baker's comment tipped me off to the core idea that in order for a view to have its size be determined by the content placed within it, then the content placed within it must have an explicit relationship with the containing view in order to drive its height (or width) dynamically. "Add subview" does not create this relationship as you might assume. You have to choose which subview is going to drive the height and/or width of the container... most commonly whatever UI element you have placed in the lower right hand corner of your overall UI. Here's some code and inline comments to illustrate the point.
Note, this may be of particular value to those working with scroll views since it's common to design around a single content view that determines its size (and communicates this to the scroll view) dynamically based on whatever you put in it. Good luck, hope this helps somebody out there.

null = True
Means there is no constraint of database for the field to be filled, so you can have an object with null value for the filled that has this option.
blank = True
Means there is no constraint of validation in django forms. so when you fill a modelForm

If you set CURLOPT_RETURNTRANSFER
to true
or 1
then the return value from curl_exec
will be the actual result from the successful operation. In other words it will not return TRUE
on success. Although it will return FALSE
on failure.
As described in the Return Values section of curl-exec
PHP manual page: http://php.net/manual/function.curl-exec.php
You should enable the CURLOPT_FOLLOWLOCATION
option for redirects but this would be a problem if your server is in safe_mode
and/or open_basedir
is in effect which can cause issues with curl as well.
This is an equivalent solution to Tim Pietzcker's answer (see also comments of same answer):
^(?!.*filename\.js$).*\.js$
It means, match *.js
except *filename.js
.
To get to this solution, you can check which patterns the negative lookbehind excludes, and then exclude exactly these patterns with a negative lookahead.
You are indeed passing the first data item to the each function.
Pass data.programs to the each function instead. Change the code to as below:
<script>
$(document).ready(function() {
var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };
$.each(data.programs, function(key,val) {
alert(key+val);
});
});
</script>
It is actually very easy. But there is no way you can achieve it directly. You need to select a service side technology. You can use anything for this part. And this is what we call a RESTful API or a SOAP API. It depends on you what to select. I have done many project with both. I would prefer REST. So what will happen you will have some scripts in your web server, and you know the URLs. For example we need to make a user registration. And for this we have
mydomain.com/v1/userregister.php
Now from the android side you will send an HTTP request to the above URL. And the above URL will handle the User Registration and will give you a response that whether the operation succeed or not.
For a complete detailed explanation of the above concept. You can visit the following link.
Ok I finally worked this out. This is using TortoiseHg on Windows. If you're not using that you can do it on the command line.
hggit
:Open a command line, enter an empty directory.
git init --bare .git
(If you don't use a bare repo you'll get an error like abort: git remote error: refs/heads/master failed to update
cd
to your Mercurial repository.
hg bookmarks hg
hg push c:/path/to/your/git/repo
In the Git directory: git config --bool core.bare false
(Don't ask me why. Something about "work trees". Git is seriously unfriendly. I swear writing the actual code is easier than using Git.)
Hopefully it will work and then you can push from that new git repo to a non-bare one.
String.equalsIgnoreCase
is the most practical choice for naive case-insensitive string comparison.
However, it is good to be aware that this method does neither do full case folding nor decomposition and so cannot perform caseless matching as specified in the Unicode standard. In fact, the JDK APIs do not provide access to information about case folding character data, so this job is best delegated to a tried and tested third-party library.
That library is ICU, and here is how one could implement a utility for case-insensitive string comparison:
import com.ibm.icu.text.Normalizer2;
// ...
public static boolean equalsIgnoreCase(CharSequence s, CharSequence t) {
Normalizer2 normalizer = Normalizer2.getNFKCCasefoldInstance();
return normalizer.normalize(s).equals(normalizer.normalize(t));
}
String brook = "?u\u0308ßchen";
String BROOK = "FLÜSSCHEN";
assert equalsIgnoreCase(brook, BROOK);
Naive comparison with String.equalsIgnoreCase
, or String.equals
on upper- or lowercased strings will fail even this simple test.
(Do note though that the predefined case folding flavour getNFKCCasefoldInstance
is locale-independent; for Turkish locales a little more work involving UCharacter.foldCase
may be necessary.)
I'm Daniel Stenberg.
I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.
I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.
Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.
Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.
Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.
At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.
Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.
Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?
Yes. So insanely much.
But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.
We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.
Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.
Yeah. For real.
Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.
But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.
curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.
This problem can appear on Windows when there are files in a directory (or in any subdirectory) which path length is greater than 260 symbols.
In such cases you need to delete \\\\?\C:\mydir
instead of C:\mydir
.
About the 260 symbols limit you can read here.
The primary key in Cassandra usually consists of two parts - Partition key and Clustering columns.
primary_key((partition_key), clustering_col )
Partition key - The first part of the primary key. The main aim of a partition key is to identify the node which stores the particular row.
CREATE TABLE phone_book ( phone_num int, name text, age int, city text, PRIMARY KEY ((phone_num, name), age);
Here, (phone_num, name) is the partition key. While inserting the data, the hash value of the partition key is generated and this value decides which node the row should go into.
Consider a 4 node cluster, each node has a range of hash values it can store. (Write) INSERT INTO phone_book VALUES (7826573732, ‘Joey’, 25, ‘New York’);
Now, the hash value of the partition key is calculated by Cassandra partitioner. say, hash value(7826573732, ‘Joey’) ? 12 , now, this row will be inserted in Node C.
(Read) SELECT * FROM phone_book WHERE phone_num=7826573732 and name=’Joey’;
Now, again the hash value of the partition key (7826573732,’Joey’) is calculated, which is 12 in our case which resides in Node C, from which the read is done.
There can be more than one partition key and clustering columns in a primary key depending on the query you are solving.
primary_key((pk1, pk2), col 1,col2)
If you're ok with POSIX, you can also use popen()
/pclose()
#include <stdio.h>
#include <stdlib.h>
int main(void) {
/* ls -al | grep '^d' */
FILE *pp;
pp = popen("ls -al", "r");
if (pp != NULL) {
while (1) {
char *line;
char buf[1000];
line = fgets(buf, sizeof buf, pp);
if (line == NULL) break;
if (line[0] == 'd') printf("%s", line); /* line includes '\n' */
}
pclose(pp);
}
return 0;
}
You may do a session and place it:
// Start session
session_start();
// Check do the person logged in
if($_SESSION['username']==NULL){
// Haven't log in
echo "You haven't log in";
}else{
// Logged in
echo "Successfully logged in!";
}
Note: you must make a form which contain $_SESSION['username'] = $login_input_username;
I use this to get the height of an element (returns float):
document.getElementById('someDiv').getBoundingClientRect().height
It also works when you use the virtual DOM. I use it in Vue like this:
this.$refs['some-ref'].getBoundingClientRect().height
For a Vue component:
this.$refs['some-ref'].$el.getBoundingClientRect().height
You seem to look for the input attribute value
, "the initial value of the control"?
<input type="text" value="Morlodenhof 7" />
https://developer.mozilla.org/de/docs/Web/HTML/Element/Input#attr-value
The problem I had was because I had made a database in my LocalDb.
If that's the case then you have to write is as shown below:
"SELECT * FROM <DatabaseName>.[dbo].[Projects]"
Replace with your database name.
You can probably also drop the "[ ]"
You can (although controverse) extend System.String
to provide a case insensitive comparison extension method:
public static bool CIEquals(this String a, String b) {
return a.Equals(b, StringComparison.CurrentCultureIgnoreCase);
}
and use as such:
x.Username.CIEquals((string)drUser["Username"]);
C# allows you to create extension methods that can serve as syntax suggar in your project, quite useful I'd say.
It's not the answer and I know this question is old and solved, I just wanted to add these bits.
You can try something like this:
List<String> list = new ArrayList<String>(Arrays.asList(array));
public ArrayList(Collection c)
Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator. The ArrayList instance has an initial capacity of 110% the size of the specified collection.

Just run setup_xampp.bat from shell (shell from XAMPP control panel)and the paths should be set automatically for the portable version of XAMPP for windows. It has worked for me.
As described here, about the Start
command, the following would start your application with the parameters you've specified:
start "svcutil" "svcutil.exe" "language:cs" "out:generatedProxy.cs" "config:app.config" "http://localhost:8000/ServiceModelSamples/service"
"svcutil"
, after the start
command, is the name given to the CMD window upon running the application specified. This is a required parameter of the start
command.
"svcutil.exe"
is the absolute or relative path to the application you want to run. Using quotation marks allows you to have spaces in the path.
After the application to start has been specified, all the following parameters are interpreted as arguments sent to the application.
This may be due to version incompatibility between your code and the version you have installed.
In my case I was using v8.12.0 for development (locally) and installed latest version v13.7.0 on the server.
So using nvm I switched the node version to v8.12.0 with the below command:
> nvm install 8.12.0 // to install the version I wanted
> nvm use 8.12.0 // use the installed version
NOTE: You need to install nvm on your system to use nvm.
You should try this solution before trying solutions like installing build-essentials or uninstalling the current node version because you could switch between versions easily than reverting all the installations/uninstallations that you've done.
You declare
int countlines(char *filename)
to take a char *
argument.
You call it like this
countlines(fp)
passing in a FILE *.
That is why you get that compile error.
You probably should change that second line to
countlines("Test.txt")
since you open the file in countlines
Your current code is attempting to open the file in two different places.
The simplest way is to use the following pattern:
http://[server]/[site]/[ListName]/[Folder]/[SubFolder]
To place a shortcut to a document library:
Since you don't want stretching (all of the other answers ignore that) you can simply set max-width and max-height like in my jsFiddle edit.
#container img {
max-height: 250px;
max-width: 250px;
}
See my example with an image that isn't a square, it doesn't stretch
For some reason, import as suggested by Ricardo didnt work for me. I got it working with following statement:
<import resource="classpath*:/spring-config.xml" />
According to eduLINQ:
The best way to get to grips with what GroupJoin does is to think of Join. There, the overall idea was that we looked through the "outer" input sequence, found all the matching items from the "inner" sequence (based on a key projection on each sequence) and then yielded pairs of matching elements. GroupJoin is similar, except that instead of yielding pairs of elements, it yields a single result for each "outer" item based on that item and the sequence of matching "inner" items.
The only difference is in return statement:
Join:
var lookup = inner.ToLookup(innerKeySelector, comparer);
foreach (var outerElement in outer)
{
var key = outerKeySelector(outerElement);
foreach (var innerElement in lookup[key])
{
yield return resultSelector(outerElement, innerElement);
}
}
GroupJoin:
var lookup = inner.ToLookup(innerKeySelector, comparer);
foreach (var outerElement in outer)
{
var key = outerKeySelector(outerElement);
yield return resultSelector(outerElement, lookup[key]);
}

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.
The first element in a collection is generally located at index 0
. The last element is at index n-1
, where n
is the Size
of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1
, you're going to get an error.
When you declare an array like this:
var array = new int[6]
The first and last elements in the array are
var firstElement = array[0];
var lastElement = array[5];
So when you write:
var element = array[5];
you are retrieving the sixth element in the array, not the fifth one.
Typically, you would loop over an array like this:
for (int index = 0; index < array.Length; index++)
{
Console.WriteLine(array[index]);
}
This works, because the loop starts at zero, and ends at Length-1
because index
is no longer less than Length
.
This, however, will throw an exception:
for (int index = 0; index <= array.Length; index++)
{
Console.WriteLine(array[index]);
}
Notice the <=
there? index
will now be out of range in the last loop iteration, because the loop thinks that Length
is a valid index, but it is not.
Lists work the same way, except that you generally use Count
instead of Length
. They still start at zero, and end at Count - 1
.
for (int index = 0; i < list.Count; index++)
{
Console.WriteLine(list[index]);
}
However, you can also iterate through a list using foreach
, avoiding the whole problem of indexing entirely:
foreach (var element in list)
{
Console.WriteLine(element.ToString());
}
You cannot index an element that hasn't been added to a collection yet.
var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]); // Throws exception.
if ([linkedStr isEqual:(id)[NSNull null]])
{
_linkedinLbl.text=@"No";
}else{
_linkedinLbl.text=@"Yes";
}
That's not how it works.
This bit ('AND' and 'OR' and 'NOT')
will evaluate as 'NOT'
. So your code is equivalent to::
while not 'NOT' in list: print 'No boolean operator'
You could try this:
while not set('AND' and 'OR' and 'NOT').union(list): print 'No boolean operator'

int indexOf(Object o)
This method returns the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element.
One more thing to consider is whether or not the class could be used in an array:
foo bar[400];
In this scenario, there is no advantage to using the default parameter.
This would certainly NOT work:
foo bar("david", 34)[400]; // NOPE
I would say that it depends on what you want to do.
If your dropdown is a component for a form that manages a state, I would leverage the two-way binding of Angular2. For this, I would use two attributes: an input one to get the associated object and an output one to notify when the state changes.
Here is a sample:
export class DropdownValue {
value:string;
label:string;
constructor(value:string,label:string) {
this.value = value;
this.label = label;
}
}
@Component({
selector: 'dropdown',
template: `
<ul>
<li *ngFor="let value of values" (click)="select(value.value)">{{value.label}}</li>
</ul>
`
})
export class DropdownComponent {
@Input()
values: DropdownValue[];
@Input()
value: string[];
@Output()
valueChange: EventEmitter;
constructor(private elementRef:ElementRef) {
this.valueChange = new EventEmitter();
}
select(value) {
this.valueChange.emit(value);
}
}
This allows you to use it this way:
<dropdown [values]="dropdownValues" [(value)]="value"></dropdown>
You can build your dropdown within the component, apply styles and manage selections internally.
Edit
You can notice that you can either simply leverage a custom event in your component to trigger the selection of a dropdown. So the component would now be something like this:
export class DropdownValue {
value:string;
label:string;
constructor(value:string,label:string) {
this.value = value;
this.label = label;
}
}
@Component({
selector: 'dropdown',
template: `
<ul>
<li *ngFor="let value of values" (click)="selectItem(value.value)">{{value.label}}</li>
</ul>
`
})
export class DropdownComponent {
@Input()
values: DropdownValue[];
@Output()
select: EventEmitter;
constructor() {
this.select = new EventEmitter();
}
selectItem(value) {
this.select.emit(value);
}
}
Then you can use the component like this:
<dropdown [values]="dropdownValues" (select)="action($event.value)"></dropdown>
Notice that the action
method is the one of the parent component (not the dropdown one).
if you have Firebug installed on Firefox, just open the url. In the network panel, right-click and select Copy as cURL. You can see all curl parameters for this web call.
Please run below code may it helps you :)
var str = "this,is,an,example";_x000D_
var strArr = str.split(',');_x000D_
var data = "";_x000D_
for(var i=0; i<strArr.length; i++){_x000D_

}_x000D_
document.getElementById('print').innerHTML = data;
_x000D_

You can also use below format:
Label1.ForeColor = System.Drawing.ColorTranslator.FromHtml("#22FF99");
and
HyperLink1.ForeColor = System.Drawing.ColorTranslator.FromHtml("#22FF99");
Your session status are set once you start a session, and by default, take the current GLOBAL value.
If you disconnected after you did SET @@GLOBAL.wait_timeout=300
, then subsequently reconnected, you'd see
SHOW SESSION VARIABLES LIKE "%wait%";
Result: 300
Similarly, at any time, if you did
mysql> SET session wait_timeout=300;
You'd get
mysql> SHOW SESSION VARIABLES LIKE 'wait_timeout';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| wait_timeout | 300 |
+---------------+-------+
You can get the total number of rows containing a specific name using:
SELECT COUNT(*) FROM tbl_foo WHERE name = 'sarmen'
Given the count, you can now get the nth row using:
SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT (n - 1), 1
Where 1 <= n <= COUNT(*) from the first query.
Example:
getting the 3rd row
SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT 2, 1
If you're trying to do stuff with the Java default system keystore (cacerts
), then the default password is changeit
.
You can list keys without needing the password (even if it prompts you) so don't take that as an indication that it is blank.
(Incidentally who in the history of Java ever has changed the default keystore password? They should have left it blank.)
This is actually tricky, especially if you plan on returning an image url for use cases where you need to concatenate strings with the onerror
condition image URL, e.g. you might want to programatically set the url
parameter in CSS.
The trick is that image loading is asynchronous by nature so the onerror
doesn't happen sunchronously, i.e. if you call returnPhotoURL
it immediately returns undefined
bcs the asynchronous method of loading/handling the image load just began.
So, you really need to wrap your script in a Promise then call it like below. NOTE: my sample script does some other things but shows the general concept:
returnPhotoURL().then(function(value){
doc.getElementById("account-section-image").style.backgroundImage = "url('" + value + "')";
});
function returnPhotoURL(){
return new Promise(function(resolve, reject){
var img = new Image();
//if the user does not have a photoURL let's try and get one from gravatar
if (!firebase.auth().currentUser.photoURL) {
//first we have to see if user han an email
if(firebase.auth().currentUser.email){
//set sign-in-button background image to gravatar url
img.addEventListener('load', function() {
resolve (getGravatar(firebase.auth().currentUser.email, 48));
}, false);
img.addEventListener('error', function() {
resolve ('//rack.pub/media/fallbackImage.png');
}, false);
img.src = getGravatar(firebase.auth().currentUser.email, 48);
} else {
resolve ('//rack.pub/media/fallbackImage.png');
}
} else {
img.addEventListener('load', function() {
resolve (firebase.auth().currentUser.photoURL);
}, false);
img.addEventListener('error', function() {
resolve ('https://rack.pub/media/fallbackImage.png');
}, false);
img.src = firebase.auth().currentUser.photoURL;
}
});
}
Add a literal space, or a tab:
public void displayCustomerInfo() {

I think it's to prevent you from mixing declarations and definitions. (Think about the problems that could occur if you include the file in multiple places.)
I use ALT-left and ALT-right to pop/push from/to the tag stack.
" Alt-right/left to navigate forward/backward in the tags stack
map <M-Left> <C-T>
map <M-Right> <C-]>
If you use hjkl
for movement you can map <M-h>
and <M-l>
instead.
You have to insert the elements using the insert method present in vectors STL, check the below program to add the elements to it, and you can use in the same way in your program.
#include <iostream>
#include <vector>
#include <string.h>
int main ()
{
std::vector<std::string> myvector ;
std::vector<std::string>::iterator it;
it = myvector.begin();
std::string myarray [] = { "Hi","hello","wassup" };
myvector.insert (myvector.begin(), myarray, myarray+3);
std::cout << "myvector contains:";
for (it=myvector.begin(); it<myvector.end(); it++)
std::cout << ' ' << *it;
std::cout << '\n';
return 0;
}
Everybody did explain why this problem occurs, but it's still very easy to forget about it and then scratching your head why you got wrong results. Especially when you're working on big sets of data when the results seem to be fine at first glance.
Using Object.entries
you ensure to go trough all properties:
var arr = [3, 5, 7];
arr.foo = "hello";
for ( var [key, val] of Object.entries( arr ) ) {
console.log( val );
}
/* Result:
3
5
7
hello
*/
If you need to insert into a specific position in the array, you can do this:
case ADD_ITEM :
return {
...state,
arr: [
...state.arr.slice(0, action.pos),
action.newItem,
...state.arr.slice(action.pos),
],
}
The explanation from Scott Meyers in Effective C++ might help understand when to use them:
Public inheritance should model "is-a relationship," whereas private inheritance should be used for "is-implemented-in-terms-of" - so you don't have to adhere to the interface of the superclass, you're just reusing the implementation.
What do you intend to do with the overlay? If it's static, say, a simple box overlapping some content, just use absolute positioning with CSS. If it's dynamic (I believe this is called a lightbox), you can write some CSS-modifying jQuery code to show/hide the overlay on-demand.
I also had this same problem.
I build .apk file of the project and installed it into mobile(android) and got it working
I'm not repeating what is instructed here to input the Key store, password, etc. Try
Build -> Generate Signed APK -> [ Input ] ---Next---> select BOTH

Kubernetes is an open source project that brings 'Google style' cluster management capabilities to the world of virtual machines, or 'on the metal' scenarios. It works very well with modern operating system environments (like CoreOS or Red Hat Atomic) that offer up lightweight computing 'nodes' that are managed for you. It is written in Golang and is lightweight, modular, portable and extensible. We (the Kubernetes team) are working with a number of different technology companies (including Mesosphere who curate the Mesos open source project) to establish Kubernetes as the standard way to interact with computing clusters. The idea is to reproduce the patterns that we see people needing to build cluster applications based on our experience at Google. Some of these concepts include:
So with Kubernetes alone you will have something that is simple, easy to get up-and-running, portable and extensible that adds 'cluster' as a noun to the things that you manage in the lightest weight manner possible. Run an application on a cluster, and stop worrying about an individual machine. In this case, cluster is a flexible resource just like a VM. It is a logical computing unit. Turn it up, use it, resize it, turn it down quickly and easily.
With Mesos, there is a fair amount of overlap in terms of the basic vision, but the products are at quite different points in their lifecycle and have different sweet spots. Mesos is a distributed systems kernel that stitches together a lot of different machines into a logical computer. It was born for a world where you own a lot of physical resources to create a big static computing cluster. The great thing about it is that lots of modern scalable data processing application run well on Mesos (Hadoop, Kafka, Spark) and it is nice because you can run them all on the same basic resource pool, along with your new age container packaged apps. It is somewhat more heavy weight than the Kubernetes project, but is getting easier and easier to manage thanks to the work of folks like Mesosphere.
Now what gets really interesting is that Mesos is currently being adapted to add a lot of the Kubernetes concepts and to support the Kubernetes API. So it will be a gateway to getting more capabilities for your Kubernetes app (high availability master, more advanced scheduling semantics, ability to scale to a very large number of nodes) if you need them, and is well suited to run production workloads (Kubernetes is still in an alpha state).
When asked, I tend to say:
Kubernetes is a great place to start if you are new to the clustering world; it is the quickest, easiest and lightest way to kick the tires and start experimenting with cluster oriented development. It offers a very high level of portability since it is being supported by a lot of different providers (Microsoft, IBM, Red Hat, CoreOs, MesoSphere, VMWare, etc).
If you have existing workloads (Hadoop, Spark, Kafka, etc), Mesos gives you a framework that let's you interleave those workloads with each other, and mix in a some of the new stuff including Kubernetes apps.
Mesos gives you an escape valve if you need capabilities that are not yet implemented by the community in the Kubernetes framework.

You have entered wrong port number 3360 instead of 3306. You dont need to write database port number if you are using daefault (3306 in case of MySQL)
I had this issue when using windows and the responses above solved it for me, however when i switched to linux (ubuntu 18.04 LTS) I had the same issue and couldn't figure out how to solve it because I didn't see the file '/usr/share/phpmyadmin/libraries/sql.lib.php'.
This sql.lib.php file wasn't in the share folder or the phpmyadmin/libraries folder of my /opt/lampp directory - since I was using xampp on my ubuntu. Based on the update made to the xampp (because I used the latest installation as of now) setup.
The answer is still to replace: (count($analyzed_sql_results['select_expr'] == 1)
With: (count($analyzed_sql_results['select_expr']) == 1
However the file to look for is Sql.php
found in /opt/lampp/phpmyadmin/libraries/classes/Sql.php
Future updates or if you still don't find it: use grep -r 'count($analyzed_sql_results' /opt/lampp/phpmyadmin
to search for matching documents in your directory and edit accordingly
We had this on a recursive query that was dumping tons of data to the output - have you double checked everything does exit and no infinite loops exist?
Might try to narrow it down with a single page - we found ANTS to not be much help in that same case either - what we ended up doing was running the site hit a page watch the CPU - hit the next page watch CPU - very methodical and time consuming but if you cant find it with some code tracing you might be out of luck -
We were able to use IIS log files to track it to a set of pages that were suspect -
Hope that helps !
Use this ^[a-zA-Z0-9_]*$
See here for more info.
I had the same problem, put the ! outside the brackets;
while ! [ -f /tmp/list.txt ];
do
echo "#"
sleep 1
done
Also, if you add an echo inside the loop it will tell you if you are getting into the loop or not.
Just make sure the label is associated with the input.
<fieldset>
<legend>What metasyntactic variables do you like?</legend>
<input type="checkbox" name="foo" value="bar" id="foo_bar">
<label for="foo_bar">Bar</label>
<input type="checkbox" name="foo" value="baz" id="foo_baz">
<label for="foo_baz">Baz</label>
</fieldset>
You can directly use (String)session.getAttribute("username"); inside scriptlet tag ie <% %>.
When I just run this as a page
<?php
echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';
exit;
it works fine.
What version of PHP are you running?
Could you try echoing something else after: $testObject->split_for_sms($Chat);
Maybe it doesn't get to that part of the code? You could also try these with the other function calls to check where your program stops/is getting to.
Hope you get a bit further with this.
You can also use START WITH
to start a sequence from a particular point, although setval accomplishes the same thing, as in Euler's answer, eg,
SELECT MAX(a) + 1 FROM foo;
CREATE SEQUENCE foo_a_seq START WITH 12345; -- replace 12345 with max above
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq');
From the documentation (help copy-item -full
):
-force <SwitchParameter>
Allows cmdlet to override restrictions such as renaming existing files as long as security is not compromised.
Required? false
Position? named
Default value False
Accept pipeline input? false
Accept wildcard characters? false
My Android Studio version 3.6.1
After getting updated the latest version I have been facing this problem for few hours. My steps to solve this:
-> Updated sdk platform-tools [though it's not fetching my device yet]
-> Change the USB cable, then my 2 devices both are getting connected with Studio and run my app successfully.
I don't know this silly step might help anyone but U can have a look on that. I just share my experience, Thanks.
Try this instead in the end:
exec (@query)
If you do not have the brackets, SQL Server assumes the value of the variable to be a stored procedure name.
OR
EXECUTE sp_executesql @query
And it should not be because of FULL JOIN.
But I hope you have already created the temp tables: #TrafficFinal, #TrafficFinal2, #TrafficFinal3 before this.
Please note that there are performance considerations between using EXEC and sp_executesql. Because sp_executesql uses forced statement caching like an sp.
More details here.
On another note, is there a reason why you are using dynamic sql for this case, when you can use the query as is, considering you are not doing any query manipulations and executing it the way it is?
This is the sort of thing that the CSS flexbox model will fix, because it will let you specify that each li will receive an equal proportion of the remaining width.
If you use as following, your code can be more effective than you wrote. You should add another feature.
.abc, .xyz {
margin-left:20px;
width: 100px;
height: 100px;
}
OR
a.abc, a.xyz {
margin-left:20px;
width: 100px;
height: 100px;
}
OR
a {
margin-left:20px;
width: 100px;
height: 100px;
}
You don't tend to execute the make file itself, rather you execute make
, giving it the make file as an argument:
make -f pax.mk
If your make file is actually one of the standard names (like makefile
or Makefile
), you don't even need to specify it. It'll be picked up by default (if you have more than one of these standard names in your build directory, you better look up the make
man page to see which takes precedence).
In a terminal emulator like konsole or gnome-terminal, you should to set a 256 color setting for vim.
:set t_Co=256
After that you can to change your background.

I was trying to find a better answer that was more standalone, so I started to think about how JQuery does events and custom events. Since click (from JQuery) is just any event, I thought that all I had to do was trigger the event given that the iframe's content has been clicked on. Thus, this was my solution
$(document).ready(function () {
$("iframe").each(function () {
//Using closures to capture each one
var iframe = $(this);
iframe.on("load", function () { //Make sure it is fully loaded
iframe.contents().click(function (event) {
iframe.trigger("click");
});
});
iframe.click(function () {
//Handle what you need it to do
});
});
});
You just need to cast it, as such:
int intPart = (int)343564564.4342
If you still want to use it as a decimal in later calculations, then Math.Truncate (or possibly Math.Floor if you want a certain behaviour for negative numbers) is the function you want.
Hope you dont mind Xml.Linq and .net3.5+
XElement ele = XElement.Load("text.xml");
String aXmlString = ele.toString(SaveOptions.DisableFormatting);
Depending on what you are interested in, you can probably skip the whole 'string' var part and just use XLinq objects
In MacOS:
Android Studio -> Preferences... -> Editor -> Color Scheme -> Color Scheme Font
Change Scheme to Dracula

Edit: code tends to return useful results when used as Google search terms. The code above doesn't. For those who need it, it's bitwise XOR as described here.

Turn off pre compiled headers:
Project Properties -> C++ -> Precompiled Headers
set Precompiled Header
to "Not Using Precompiled Header"
.
Other answers here seem to favor omitting the trailing slash. There is one case in which a trailing slash will help with search engine optimization (SEO). That is the case that your document has what appears to be a file extension that is not .html
. This becomes an issue with sites that are rating websites. They might choose between these two urls:
http://mysite.example.com/rated.example.com
http://mysite.example.com/rated.example.com/
In such a case, I would choose the one with the trailing slash. That is because the .com
extension is an extension for Windows executable command files. Search engines and virus checkers often dislike URLs that appear that they may contain malware distributed through such mechanisms. The trailing slash seems to mitigate any concerns, allowing the page to rank in search engines and get by virus checkers.
If your URLs have no .
in the file portion, then I would recommend omitting the trailing slash for simplicity.
I was stumped by this. Once I got passed the 255 problem... I ended up with a mysterious error code 1. This is the foo to get that resolved:
pssh -x '-tt' -h HOSTFILELIST -P "sudo yum -y install glibc"
-P means write the output out as you go and is optional. But the -x '-tt' trick is what forces a psuedo tty to be allocated.
You can get a clue what the error code 1 means this if you try:
ssh AHOST "sudo yum -y install glibc"
You may see:
[slc@bastion-ci ~]$ ssh MYHOST "sudo yum -y install glibc"
sudo: sorry, you must have a tty to run sudo
[slc@bastion-ci ~]$ echo $?
1
Notice the return code for this is 1, which is what pssh is reporting to you.
I found this -x -tt trick here. Also note that turning on verbose mode (pssh --verbose) for these cases does nothing to help you.
This is how you do a distinct count query. Note that you have to filter out the nulls.
var useranswercount = (from a in tpoll_answer
where user_nbr != null && answer_nbr != null
select user_nbr).Distinct().Count();
If you combine this with into your current grouping code, I think you'll have your solution.
Two suggestions with @Vivek Parihar's solution :
If we are presenting any viewController we should check nil for “visibleViewController” in navigationController extension
extension UINavigationController {
public override func shouldAutorotate() -> Bool {
var shouldAutorotate = false
if visibleViewController != nil {
shouldAutorotate = visibleViewController.shouldAutorotate()
}
return shouldAutorotate
}
public override func supportedInterfaceOrientations() -> Int {
return visibleViewController.supportedInterfaceOrientations()
}
}
If We are using any action sheet to present and user will rotate upsideDown, Your action sheet will open from top edge of the screen :P, to solve this, we should take Portrait only
override func shouldAutorotate() -> Bool {
if (UIDevice.currentDevice().orientation == UIDeviceOrientation.Portrait ||
UIDevice.currentDevice().orientation == UIDeviceOrientation.Unknown) {
return true
}
else {
return false
}
}
override func supportedInterfaceOrientations() -> Int {
return Int(UIInterfaceOrientationMask.Portrait.rawValue)
}
You may use line-height on div1 as below:
<div id="div1" style="line-height:0px;">
<div></div><div></div><div></div><br/><div></div><div></div><div></div>
</div>
See this: http://jsfiddle.net/wCpU8/
Your '/0'
should be '\0'
.. you got the slash reversed/leaning the wrong way. Your while
should look like:
while (*(forward++)!='\0')
though the != '\0'
part of your expression is optional here since the loop will continue as long as it evaluates to non-zero (null is considered zero and will terminate the loop).
All "special" characters (i.e., escape sequences for non-printable characters) use a backward slash, such as tab '\t'
, or newline '\n'
, and the same for null '\0'
so it's easy to remember.
Your method doesn't have any callbacks so there is no reason to use .CallBack()
. You can simply return a Task with the desired values using .Returns()
and Task.FromResult, e.g.:
MyType someValue=...;
mock.Setup(arg=>arg.DoSomethingAsync())
.Returns(Task.FromResult(someValue));
Update 2014-06-22
Moq 4.2 has two new extension methods to assist with this.
mock.Setup(arg=>arg.DoSomethingAsync())
.ReturnsAsync(someValue);
mock.Setup(arg=>arg.DoSomethingAsync())
.ThrowsAsync(new InvalidOperationException());
Update 2016-05-05
As Seth Flowers mentions in the other answer, ReturnsAsync
is only available for methods that return a Task<T>
. For methods that return only a Task,
.Returns(Task.FromResult(default(object)))
can be used.
As shown in this answer, in .NET 4.6 this is simplified to .Returns(Task.CompletedTask);
, e.g.:
mock.Setup(arg=>arg.DoSomethingAsync())
.Returns(Task.CompletedTask);
The easiest way is to use the shell_exec command to execute a bash script, passing in the values as parameters. From there, you can manipulate crontabs like you would in any other non-interactive script, and also ensure that you have the correct permissions by using sudo etc.
See this, Crontab without crontab -e, for more info.
The capitalization is wrong, and you have an extra argument.
Do this instead:
$('img#thumb').removeAttr('id');
For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

Something like this?
public static T ConvertValue<T>(string value)
{
return (T)Convert.ChangeType(value, typeof(T));
}
You can then use it like this:
int val = ConvertValue<int>("42");
Edit:
You can even do this more generic and not rely on a string
parameter provided the type U
implements IConvertible
- this means you have to specify two type parameters though:
public static T ConvertValue<T,U>(U value) where U : IConvertible
{
return (T)Convert.ChangeType(value, typeof(T));
}
I considered catching the InvalidCastException
exception that might be raised by Convert.ChangeType()
- but what would you return in this case? default(T)
? It seems more appropriate having the caller deal with the exception.
Ubuntu uses AppArmor and that is whats preventing you from accessing /data/. Fedora uses selinux and that would prevent this on a RHEL/Fedora/CentOS machine.
To modify AppArmor to allow MySQL to access /data/ do the follow:
sudo gedit /etc/apparmor.d/usr.sbin.mysqld
add this line anywhere in the list of directories:
/data/ rw,
then do a :
sudo /etc/init.d/apparmor restart
Another option is to disable AppArmor for mysql altogether, this is NOT RECOMMENDED:
sudo mv /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/
Don't forget to restart apparmor:
sudo /etc/init.d/apparmor restart
I believe you have libx264
installed and configured with ffmpeg
to convert video to h264
... Then you can try with -vcodec libx264
... The -format
option is for showing available formats, this is not a conversion option I think...
Try something like this:
try {
$w = New-Object net.WebClient
$d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
Write-Host $_.Exception.ToString()
}
The exception is in the $_
variable. You might explore $_
like this:
try {
$w = New-Object net.WebClient
$d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
$_ | fl * -Force
}
I think it will give you all the info you need.
My rule: if there is some data that is not displayed, try to use -force
.
As @Devart says, the total length of your index is too long.
The short answer is that you shouldn't be indexing such long VARCHAR columns anyway, because the index will be very bulky and inefficient.
The best practice is to use prefix indexes so you're only indexing a left substring of the data. Most of your data will be a lot shorter than 255 characters anyway.
You can declare a prefix length per column as you define the index. For example:
...
KEY `index` (`parent_menu_id`,`menu_link`(50),`plugin`(50),`alias`(50))
...
But what's the best prefix length for a given column? Here's a method to find out:
SELECT
ROUND(SUM(LENGTH(`menu_link`)<10)*100/COUNT(`menu_link`),2) AS pct_length_10,
ROUND(SUM(LENGTH(`menu_link`)<20)*100/COUNT(`menu_link`),2) AS pct_length_20,
ROUND(SUM(LENGTH(`menu_link`)<50)*100/COUNT(`menu_link`),2) AS pct_length_50,
ROUND(SUM(LENGTH(`menu_link`)<100)*100/COUNT(`menu_link`),2) AS pct_length_100
FROM `pds_core_menu_items`;
It tells you the proportion of rows that have no more than a given string length in the menu_link
column. You might see output like this:
+---------------+---------------+---------------+----------------+
| pct_length_10 | pct_length_20 | pct_length_50 | pct_length_100 |
+---------------+---------------+---------------+----------------+
| 21.78 | 80.20 | 100.00 | 100.00 |
+---------------+---------------+---------------+----------------+
This tells you that 80% of your strings are less than 20 characters, and all of your strings are less than 50 characters. So there's no need to index more than a prefix length of 50, and certainly no need to index the full length of 255 characters.
PS: The INT(1)
and INT(32)
data types indicates another misunderstanding about MySQL. The numeric argument has no effect related to storage or the range of values allowed for the column. INT
is always 4 bytes, and it always allows values from -2147483648 to 2147483647. The numeric argument is about padding values during display, which has no effect unless you use the ZEROFILL
option.
Both Function.prototype.call()
and Function.prototype.apply()
call a function with a given this
value, and return the return value of that function.
Function.prototype.bind()
, on the other hand, creates a new function with a given this
value, and returns that function without executing it.
So, let's take a function that looks like this :
var logProp = function(prop) {
console.log(this[prop]);
};
Now, let's take an object that looks like this :
var Obj = {
x : 5,
y : 10
};
We can bind our function to our object like this :
Obj.log = logProp.bind(Obj);
Now, we can run Obj.log
anywhere in our code :
Obj.log('x'); // Output : 5
Obj.log('y'); // Output : 10
Where it really gets interesting, is when you not only bind a value for this
, but also for for its argument prop
:
Obj.logX = logProp.bind(Obj, 'x');
Obj.logY = logProp.bind(Obj, 'y');
We can now do this :
Obj.logX(); // Output : 5
Obj.logY(); // Output : 10
<div *ngIf="currentStatus !== ('status1' || 'status2' || 'status3' || 'status4')">

Although this question is bit old, the issue was caused by corrupted ClearType registry setting and resolved by fixing it, as described in this ClearType, install4j and case of Java bug post.
ClearType, install4j and case of Java bug Java
Do you know what ClearType (font-smoothing technology in Windows) has in common with Java (programming language and one of the recommended frameworks)?
Nothing except that they were working together hard at making me miserable for few months. I had some Java software that I couldn’t install. I mean really couldn’t – not even figure out reason or reproduce it on another PC.
Recently I was approved for Woopra beta (site analytics service) and it uses desktop client written in Java… I couldn’t install. That got me really mad. :)
Story All of the software in question was similar :
setup based on install4j; setup crashing with bunch of errors. I was blaming install4j during early (hundred or so) attempts to solve issue. Later I slowly understood that if it was that bugged for that long time – solution would have been created and googled.
Tracing After shifting focus from install4j I decided to push Java framework. I was trying stable versions earlier so decided to go for non-stable 1.6 Update 10 Release Candidate.
This actually fixed error messages but not crashes. I had also noticed that there was new error log created in directory with setup files. Previously I had only seen logs in Windows temporary directory.
New error log was saying following :
Could not display the GUI. This application needs access to an X Server. If you have access there is probably an X library missing. ******************************************************************* You can also run this application in console mode without access to an X server by passing the argument -c Very weird to look for X-Server on non-Linux PC, isn’t it? So I decided to try that “-c” argument. And was actually able to install in console mode.
Happy ending? Nope. Now installed app was crashing. But it really got me thinking. If console works but graphical interface doesn’t – there must be problem with latter.
One more error log (in application folder) was now saying (among other things) :
Caused by: java.lang.IllegalArgumentException: -60397977 incompatible with Text-specific LCD contrast key Which successfully googled me description of bug with Java unable to read non-standard ClearType registry setting.
Solution I immediately launched ClearType Tuner from Control Panel and found setting showing gibberish number. After correcting it to proper one all problems with Java were instantly gone.

I'm not sure that this is the best way to do it, but when I'm deploying Ruby GUI apps (not Python, but has the same "problem" as far as .exe's are concerned) on Windows, I just write a short launcher in C# that calls on my main script. It compiles to an executable, and I then have an application executable.
Use String.fromCharCode
. This returns a string from a Unicode value, which matches the first 128 characters of ASCII.
var a = String.fromCharCode(97);
The error occurs when your repository does not have the default branch set for the remote. You can use the git remote set-head
command to modify the default branch, and thus be able to use the remote name instead of a specified branch in that remote.
To query the remote (in this case origin
) for its HEAD
(typically master
), and set that as the default branch:
$ git remote set-head origin --auto
If you want to use a different default remote branch locally, you can specify that branch:
$ git remote set-head origin new-default
Once the default branch is set, you can use just the remote name in git rebase <remote>
and any other commands instead of explicit <remote>/<branch>
.
Behind the scenes, this command updates the reference in .git/refs/remotes/origin/HEAD
.
$ cat .git/refs/remotes/origin/HEAD
ref: refs/remotes/origin/master
See the git-remote man page for further details.
Yes. IE7+ supports attribute selectors:
input[type=radio]
input[type^=ra]
input[type*=d]
input[type$=io]
Element input with attribute type which contains a value that is equal to, begins with, contains or ends with a certain value.
Other safe (IE7+) selectors are:
p > span { font-weight: bold; }
span ~ span { color: blue; }
Which for <p><span/><span/></p>
would effectively give you:
<p>
<span style="font-weight: bold;">
<span style="font-weight: bold; color: blue;">
</p>
Further reading: Browser CSS compatibility on quirksmode.com
I'm surprised that everyone else thinks it can't be done. CSS attribute selectors have been here for some time already. I guess it's time we clean up our .css files.
Although officially there is no limit specified by RFC 2616, many security protocols and recommendations state that maxQueryStrings on a server should be set to a maximum character limit of 1024. While the entire URL, including the querystring, should be set to a max of 2048 characters. This is to prevent the Slow HTTP Request DDOS vulnerability on a web server. This typically shows up as a vulnerability on the Qualys Web Application Scanner and other security scanners.
Please see the below example code for Windows IIS Servers with Web.config:
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxQueryString="1024" maxUrl="2048">
<headerLimits>
<add header="Content-type" sizeLimit="100" />
</headerLimits>
</requestLimits>
</requestFiltering>
</security>
</system.webServer>
This would also work on a server level using machine.config.
Note: Limiting query string and URL length may not completely prevent Slow HTTP Requests DDOS attack but it is one step you can take to prevent it.
You won't gain anything by checking that the key exists. This is the code of HashMap
:
@Override
public boolean containsKey(Object key) {
Entry<K, V> m = getEntry(key);
return m != null;
}
@Override
public V get(Object key) {
Entry<K, V> m = getEntry(key);
if (m != null) {
return m.value;
}
return null;
}
Just check if the return value for get()
is different from null
.
This is the HashMap source code.

None of the above solutions worked for me. But
#include <Windows.h>
worked fine.
I think it depends on the operations you'll be needing to do most frequently.
If you need the full value as a decimal number, then use decimal with appropriate precision and scale. Float is way beyond your needs, I believe.
If you'll be converting to/from degºmin'sec"fraction notation often, I'd consider storing each value as an integer type (smallint, tinyint, tinyint, smallint?).
You can use theme_get()
to display the possible options for theme.
You can control the legend font size using:
+ theme(legend.text=element_text(size=X))
replacing X with the desired size.
tl;dr: (try it here)
If you have the following HTML:
<div id="menu" style="display: none;">
<!-- menu stuff in here -->
<ul><li>Menu item</li></ul>
</div>
<div class="parent">Hover over me to show the menu here</div>
then you can use the following JavaScript code:
$(".parent").mouseover(function() {
// .position() uses position relative to the offset parent,
var pos = $(this).position();
// .outerWidth() takes into account border and padding.
var width = $(this).outerWidth();
//show the menu directly over the placeholder
$("#menu").css({
position: "absolute",
top: pos.top + "px",
left: (pos.left + width) + "px"
}).show();
});
But it doesn't work!
This will work as long as the menu and the placeholder have the same offset parent. If they don't, and you don't have nested CSS rules that care where in the DOM the #menu
element is, use:
$(this).append($("#menu"));
just before the line that positions the #menu
element.
But it still doesn't work!
You might have some weird layout that doesn't work with this approach. In that case, just use jQuery.ui's position plugin (as mentioned in an answer below), which handles every conceivable eventuality. Note that you'll have to show()
the menu element before calling position({...})
; the plugin can't position hidden elements.
Update notes 3 years later in 2012:
(The original solution is archived here for posterity)
So, it turns out that the original method I had here was far from ideal. In particular, it would fail if:
Luckily, jQuery introduced methods (position()
and outerWidth()
) way back in 1.2.6 that make finding the right values in the latter case here a lot easier. For the former case, append
ing the menu element to the placeholder works (but will break CSS rules based on nesting).
I would override your Tuple with a proper GetHashCode, and just use it as the key.
As long as you overload the proper methods, you should see decent performance.
CGRect screenBounds = [[UIScreen mainScreen] bounds];
That will give you the entire screen's resolution in points, so it would most typically be 320x480 for iPhones. Even though the iPhone4 has a much larger screen size iOS still gives back 320x480 instead of 640x960. This is mostly because of older applications breaking.
CGFloat screenScale = [[UIScreen mainScreen] scale];
This will give you the scale of the screen. For all devices that do not have Retina Displays this will return a 1.0f, while Retina Display devices will give a 2.0f and the iPhone 6 Plus (Retina HD) will give a 3.0f.
Now if you want to get the pixel width & height of the iOS device screen you just need to do one simple thing.
CGSize screenSize = CGSizeMake(screenBounds.size.width * screenScale, screenBounds.size.height * screenScale);
By multiplying by the screen's scale you get the actual pixel resolution.
A good read on the difference between points and pixels in iOS can be read here.
EDIT: (Version for Swift)
let screenBounds = UIScreen.main.bounds
let screenScale = UIScreen.main.scale
let screenSize = CGSize(width: screenBounds.size.width * screenScale, height: screenBounds.size.height * screenScale)
The easiest way is to use Sys Internals Autoruns
Start it in admin mode and then you can remove obsolete services by delete key
Your @JsonSubTypes
declaration does not make sense: it needs to list implementation (sub-) classes, NOT the class itself (which would be pointless). So you need to modify that entry to list sub-class(es) there are; or use some other mechanism to register sub-classes (SimpleModule
has something like addAbstractTypeMapping
).
size_t
is an unsigned type. So, it cannot represent any negative values(<0). You use it when you are counting something, and are sure that it cannot be negative. For example, strlen()
returns a size_t
because the length of a string has to be at least 0.
In your example, if your loop index is going to be always greater than 0, it might make sense to use size_t
, or any other unsigned data type.
When you use a size_t
object, you have to make sure that in all the contexts it is used, including arithmetic, you want non-negative values. For example, let's say you have:
size_t s1 = strlen(str1);
size_t s2 = strlen(str2);
and you want to find the difference of the lengths of str2
and str1
. You cannot do:
int diff = s2 - s1; /* bad */
This is because the value assigned to diff
is always going to be a positive number, even when s2 < s1
, because the calculation is done with unsigned types. In this case, depending upon what your use case is, you might be better off using int
(or long long
) for s1
and s2
.
There are some functions in C/POSIX that could/should use size_t
, but don't because of historical reasons. For example, the second parameter to fgets
should ideally be size_t
, but is int
.
Just create your own action.

Never construct BigDecimals from floats or doubles. Construct them from ints or strings. floats and doubles loose precision.
This code works as expected (I just changed the type from double to String):
public static void main(String[] args) {
String doubleVal = "1.745";
String doubleVal1 = "0.745";
BigDecimal bdTest = new BigDecimal( doubleVal);
BigDecimal bdTest1 = new BigDecimal( doubleVal1 );
bdTest = bdTest.setScale(2, BigDecimal.ROUND_HALF_UP);
bdTest1 = bdTest1.setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println("bdTest:"+bdTest); //1.75
System.out.println("bdTest1:"+bdTest1);//0.75, no problem
}
The simple solution is to put it in an iframe and hope that the user has a plug-in that supports it.
(I don't, the Acrobat plugin has been such a resource hog and source of instability that I make a point to remove it from any browser that it touches).
The complicated, but relative popular solution is to display it in a flash applet.
@cOnstructOr provided a great idea, but it left a comma in place

Hibernate is not going to make it easy for you to do what you are trying to do. From the Hibernate documentation:
Note that when using referencedColumnName to a non primary key column, the associated class has to be Serializable. Also note that the referencedColumnName to a non primary key column has to be mapped to a property having a single column (other cases might not work). (emphasis added)
So if you are unwilling to make AnEmbeddableObject
the Identifier for Bar then Hibernate is not going to lazily, automatically retrieve Bar for you. You can, of course, still use HQL to write queries that join on AnEmbeddableObject
, but you lose automatic fetching and life cycle maintenance if you insist on using a multi-column non-primary key for Bar.
Had the issue again when i moved from one machine to another and had everything reinstalled. In my case, i'm using both 32bit and 64bit Oracle ODP.NET installs.
When listing the assemblies on my new machine i ended up with the following list

only 64bit DLLs to be seen here.
I couldn't see it from the web.config but the one i was using was a 32bit version.
When checking my old machine with the GACutil, i saw more DLLs, also the X86 ones.
Fixed by reapplying the registration process(both x32/x64 version referenced here)

after that , Visual Studio was a happy bunny and compiled everything again for me.
I've fixed the problem in my case very easy:
go to Build- Path->Configure Build Path->Order and Export and ensure that <project name>/gen folder is above <project name>/src
After fixing the order the error disappears.
awk '/Dansk/{a=1}/Norsk/{b=1}/Svenska/{c=1}END{ if (a && b && c) print "0" }'
you can then catch the return value with the shell
if you have Ruby(1.9+)
ruby -0777 -ne 'print if /Dansk/ and /Norsk/ and /Svenka/' file
You can create a list of objects in one line using a list comprehension.

Yes, for scalar values, a combination of implode and array_slice will do:
$bar = implode(array_slice($array, 0, 1));
$bin = implode(array_slice($array, 1, 1));
$ipsum = implode(array_slice($array, 2, 1));
Or mix it up with array_values
and list
(thanks @nikic) so that it works with all types of values:
list($bar) = array_values(array_slice($array, 0, 1));
When you trying to build and run the current scheme but encounter this alert message:
"The run destination iPhone is not valid for Running the scheme."
Plus you already check your phone and it is connect to your Mac properly, all you need to do is just simply restart your Xcode and build it again. That will do the job.
