This can be because of following reason:
one of the jar files inside project was using an older version of google play services.
use multiDexEnabled true
in defaultconfig
Be specific with classes you add in dependencies. like
compile 'com.google.android.gms:play-services-maps:8.4.0'
Not like compile 'com.google.android.gms:play-services:+'
Those who are getting same error in Android 3.0.1,can resolve it by simply update the versions of compileSdkVersion and targetSdkVersion to 27 and also Implement com.android.support:appcompat-v7:27.1.1' in dependencies.
For anyone still strugging (like me...) after the above more expert replies, this works in Visual Studio 2019:
outputString = Regex.Replace(inputString, @"\W", "_");
Remember to add
using System.Text.RegularExpressions;
Eventhough it is an old question, this may help someone.
We can choose multiple files while browsing for a file using "multiple"
<input type="file" name="datafile" size="40" multiple>
With fscanf
read the file until you encounter ';'
or \n
, then you can just skip it with fscang(f, "%*c")
.
int main()
{
char str[128];
int result;
FILE* f = fopen("test.txt", "r");
...
do {
result = fscanf(f, "%127[^;\n]", str);
if(result == 0)
{
result = fscanf(f, "%*c");
}
else
{
//whatever you want to do with your value
printf("%s\n", str);
}
} while(result != EOF);
return 0;
}
The mysqli_query()
method returns an object resource to your $result
variable, not a string.
You need to loop it up and then access the records. You just can't directly use it as your $result
variable.
while ($row = $result->fetch_assoc()) {
echo $row['classtype']."<br>";
}
According to the Microsoft documentation, the TimeSpan structure exposes Hours, Minutes, Seconds, and Milliseconds as integer members. Maybe you want something like:
dateDifference.Hours.ToString() + " hrs, " + dateDifference.Minutes.ToString() + " mins, " + dateDifference.Seconds.ToString() + " secs"
If you deal regularly with Attributes in Reflection, it is very, very practical to define some extension methods. You will see that in many projects out there. This one here is one I often have:
public static bool HasAttribute<T>(this ICustomAttributeProvider provider) where T : Attribute
{
var atts = provider.GetCustomAttributes(typeof(T), true);
return atts.Length > 0;
}
which you can use like typeof(Foo).HasAttribute<BarAttribute>();
Other projects (e.g. StructureMap) have full-fledged ReflectionHelper classes that use Expression trees to have a fine syntax to identity e.g. PropertyInfos. Usage then looks like that:
ReflectionHelper.GetProperty<Foo>(x => x.MyProperty).HasAttribute<BarAttribute>()
I modified @JayRiggs' answer, and this works. You need the if
because sometimes the SelectedRows may be empty, so the index operation will throw a exception.
if (yourDGV.SelectedRows.Count>0){
int index = yourDGV.SelectedRows[0].Index;
}
You can solve it with Joda Time:
Date utcDate = new Date(timezoneFrom.convertLocalToUTC(date.getTime(), false));
Date localDate = new Date(timezoneTo.convertUTCToLocal(utcDate.getTime()));
Java 8:
LocalDateTime localDateTime = LocalDateTime.parse("2007-12-03T10:15:30");
ZonedDateTime fromDateTime = localDateTime.atZone(
ZoneId.of("America/Toronto"));
ZonedDateTime toDateTime = fromDateTime.withZoneSameInstant(
ZoneId.of("Canada/Newfoundland"));
On top of what the others have already stated, some sort of server-side scripting is necessary in order for the server to read and save the file.
Using PHP might be a good choice, but you're free to use any server-side scripting language. http://www.w3schools.com/php/php_file_upload.asp may be of use on that end.
Make sure you click the properties on the file and set it to "copy always" or it will not be in the Debug\ folder with your happy lil dll's to configure where it needs to be and add more cowbell
Yet another way using just bash and grep:
For a single file 'test.txt':
grep -q Dansk test.txt && grep -q Norsk test.txt && grep -l Svenska test.txt
Will print test.txt
iff the file contains all three (in any combination). The first two greps don't print anything (-q
) and the last only prints the file if the other two have passed.
If you want to do it for every file in the directory:
for f in *; do grep -q Dansk $f && grep -q Norsk $f && grep -l Svenska $f; done
You're right, no API at all that I'm aware to export PrivateKey marked as non-exportable. But if you patch (in memory) normal APIs, you can use the normal way to export :)
There is a new version of mimikatz that also support CNG Export (Windows Vista / 7 / 2008 ...)
Run it and enter the following commands in its prompt:
privilege::debug
(unless you already have it or target only CryptoApi)crypto::patchcng
(nt 6) and/or crypto::patchcapi
(nt 5 & 6)crypto::exportCertificates
and/or crypto::exportCertificates CERT_SYSTEM_STORE_LOCAL_MACHINE
The exported .pfx files are password protected with the password "mimikatz"
Just use vanilla JS. You can use splice
to remove the element:
obj.subTopics.splice(1, 1);
If using the .NET 2.0 (or later) framework you can use the CopyFromScreen()
method detailed here:
http://www.geekpedia.com/tutorial181_Capturing-screenshots-using-Csharp.html
//Create a new bitmap.
var bmpScreenshot = new Bitmap(Screen.PrimaryScreen.Bounds.Width,
Screen.PrimaryScreen.Bounds.Height,
PixelFormat.Format32bppArgb);
// Create a graphics object from the bitmap.
var gfxScreenshot = Graphics.FromImage(bmpScreenshot);
// Take the screenshot from the upper left corner to the right bottom corner.
gfxScreenshot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
Screen.PrimaryScreen.Bounds.Y,
0,
0,
Screen.PrimaryScreen.Bounds.Size,
CopyPixelOperation.SourceCopy);
// Save the screenshot to the specified path that the user has chosen.
bmpScreenshot.Save("Screenshot.png", ImageFormat.Png);
For those people using Python, you may consider using Selenium Wire, which can set request headers, as well as provide you with the ability to inspect requests and responses.
from seleniumwire import webdriver # Import from seleniumwire
# Create a new instance of the Firefox driver (or Chrome)
driver = webdriver.Firefox()
# Create a request interceptor
def interceptor(request):
del request.headers['Referer'] # Delete the header first
request.headers['Referer'] = 'some_referer'
# Set the interceptor on the driver
driver.request_interceptor = interceptor
# All requests will now use 'some_referer' for the referer
driver.get('https://mysite')
You should use readfile()
:
readfile("/path/to/file");
This will read the file and send it to the browser in one command. This is essentially the same as:
echo file_get_contents("/path/to/file");
except that file_get_contents()
may cause the script to crash for large files, while readfile()
won't.
You could use Synonyms part in the database.
Then in view wizard from Synonyms tab find your saved synonyms and add to view and set inner join simply.
$("#reset").on("click", function () {
$('#my_select').prop('selectedIndex',0);
});
So you can just revert the file that you deleted but remember, If you are working on any type of project with a set project file (like iOS), reverting the file will add it to your system folder structure but not your project file structure. additional steps may be required if you are in this case
I had this problem in a project this morning. Make sure you specify the base tag in the head section.
It should be like this:
<head>
<base target="name_of_iframe">
</head>
That way when you click a link on the page it will open up inside of the iframe by default.
Hope that helped.
IRB has a setting for this awful "feature", which you can customize.
Create a file called ~/.irbrc
that includes the following line:
IRB.conf[:BACK_TRACE_LIMIT] = 100
This will allow you to see 100 stack frames in irb
, at least. I haven't been able to find an equivalent setting for the non-interactive runtime.
Detailed information about IRB customization can be found in the Pickaxe book.
char * const a;
*a
is writable, but a
is not; in other words, you can modify the value pointed to by a
, but you cannot modify a
itself. a
is a constant pointer to char
.
const char * a;
a
is writable, but *a
is not; in other words, you can modify a
(pointing it to a new location), but you cannot modify the value pointed to by a
.
Note that this is identical to
char const * a;
In this case, a
is a pointer to a const char
.
That will be possible only if the HTML file is also loaded with the file
protocol from the local user's harddisk.
If the HTML page is served by HTTP from a server, you can't access any local files by specifying them in a src
attribute with the file://
protocol as that would mean you could access any file on the users computer without the user knowing which would be a huge security risk.
As Dimitar Bonev said, you can access a file if the user selects it using a file selector on their own. Without that step, it's forbidden by all browsers for good reasons. Thus, while his answer might prove useful for many people, it loosens the requirement from the code in the original question.

I'll interpret your question as two questions: 1) why ->
even exists, and 2) why .
does not automatically dereference the pointer. Answers to both questions have historical roots.
Why does ->
even exist?
In one of the very first versions of C language (which I will refer as CRM for "C Reference Manual", which came with 6th Edition Unix in May 1975), operator ->
had very exclusive meaning, not synonymous with *
and .
combination
The C language described by CRM was very different from the modern C in many respects. In CRM struct members implemented the global concept of byte offset, which could be added to any address value with no type restrictions. I.e. all names of all struct members had independent global meaning (and, therefore, had to be unique). For example you could declare
struct S {
int a;
int b;
};
and name a
would stand for offset 0, while name b
would stand for offset 2 (assuming int
type of size 2 and no padding). The language required all members of all structs in the translation unit either have unique names or stand for the same offset value. E.g. in the same translation unit you could additionally declare
struct X {
int a;
int x;
};
and that would be OK, since the name a
would consistently stand for offset 0. But this additional declaration
struct Y {
int b;
int a;
};
would be formally invalid, since it attempted to "redefine" a
as offset 2 and b
as offset 0.
And this is where the ->
operator comes in. Since every struct member name had its own self-sufficient global meaning, the language supported expressions like these
int i = 5;
i->b = 42; /* Write 42 into `int` at address 7 */
100->a = 0; /* Write 0 into `int` at address 100 */
The first assignment was interpreted by the compiler as "take address 5
, add offset 2
to it and assign 42
to the int
value at the resultant address". I.e. the above would assign 42
to int
value at address 7
. Note that this use of ->
did not care about the type of the expression on the left-hand side. The left hand side was interpreted as an rvalue numerical address (be it a pointer or an integer).
This sort of trickery was not possible with *
and .
combination. You could not do
(*i).b = 42;
since *i
is already an invalid expression. The *
operator, since it is separate from .
, imposes more strict type requirements on its operand. To provide a capability to work around this limitation CRM introduced the ->
operator, which is independent from the type of the left-hand operand.
As Keith noted in the comments, this difference between ->
and *
+.
combination is what CRM is referring to as "relaxation of the requirement" in 7.1.8: Except for the relaxation of the requirement that E1
be of pointer type, the expression E1->MOS
is exactly equivalent to (*E1).MOS
Later, in K&R C many features originally described in CRM were significantly reworked. The idea of "struct member as global offset identifier" was completely removed. And the functionality of ->
operator became fully identical to the functionality of *
and .
combination.
Why can't .
dereference the pointer automatically?
Again, in CRM version of the language the left operand of the .
operator was required to be an lvalue. That was the only requirement imposed on that operand (and that's what made it different from ->
, as explained above). Note that CRM did not require the left operand of .
to have a struct type. It just required it to be an lvalue, any lvalue. This means that in CRM version of C you could write code like this
struct S { int a, b; };
struct T { float x, y, z; };
struct T c;
c.b = 55;
In this case the compiler would write 55
into an int
value positioned at byte-offset 2 in the continuous memory block known as c
, even though type struct T
had no field named b
. The compiler would not care about the actual type of c
at all. All it cared about is that c
was an lvalue: some sort of writable memory block.
Now note that if you did this
S *s;
...
s.b = 42;
the code would be considered valid (since s
is also an lvalue) and the compiler would simply attempt to write data into the pointer s
itself, at byte-offset 2. Needless to say, things like this could easily result in memory overrun, but the language did not concern itself with such matters.
I.e. in that version of the language your proposed idea about overloading operator .
for pointer types would not work: operator .
already had very specific meaning when used with pointers (with lvalue pointers or with any lvalues at all). It was very weird functionality, no doubt. But it was there at the time.
Of course, this weird functionality is not a very strong reason against introducing overloaded .
operator for pointers (as you suggested) in the reworked version of C - K&R C. But it hasn't been done. Maybe at that time there was some legacy code written in CRM version of C that had to be supported.
(The URL for the 1975 C Reference Manual may not be stable. Another copy, possibly with some subtle differences, is here.)
/* here is what works for me - set up as a class */
.button {
text-align: center;
display: block;
margin: 0 auto;
}
/* you can set padding and width to whatever works best */
I think this is what you're looking for: PAW Server from http://paw-android.fun2code.de/

UTF-8 is prepared for world domination, Latin1 isn't.
If you're trying to store non-Latin characters like Chinese, Japanese, Hebrew, Russian, etc using Latin1 encoding, then they will end up as mojibake. You may find the introductory text of this article useful (and even more if you know a bit Java).
Note that full 4-byte UTF-8 support was only introduced in MySQL 5.5. Before that version, it only goes up to 3 bytes per character, not 4 bytes per character. So, it supported only the BMP plane and not e.g. the Emoji plane. If you want full 4-byte UTF-8 support, upgrade MySQL to at least 5.5 or go for another RDBMS like PostgreSQL. In MySQL 5.5+ it's called utf8mb4
.
From what I've read, the need for constexpr comes from an issue in metaprogramming. Trait classes may have constants represented as functions, think: numeric_limits::max(). With constexpr, those types of functions can be used in metaprogramming, or as array bounds, etc etc.
Another example off of the top of my head would be that for class interfaces, you may want derived types define their own constants for some operation.
Edit:
After poking around on SO, it looks like others have come up with some examples of what might be possible with constexprs.
You can achieve that in most pythonic way like that:
python3:
"{:0.0f}".format(num)
Unload & reload the project fixed this problem.
In my case you should put the function in $(document).ready
$(document).ready(function () {
$('div#page').on('scroll', function () {
...
});
});
I suppose that you needed that in form of a script, but if someone else just want to have a look through the Jenkins GUI, that list can be found by selecting the "Environment Variables" section in contextual left menu of every build Select project => Select build => Environment Variables
you can call the button_click event by passing..
private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
}
private void ChildNode_Click(object sender, RoutedEventArgs args)
{
SubGraphButton_Click(sender, args);
}
Also without passing..
private void SubGraphButton_Click(object sender, EventArgs args)
{
}
private void Some_Method() //this method is called
{
SubGraphButton_Click(new object(), new EventArgs());
}
You can convert char to int and viceversa easily because for the machine an int and a char are the same, 8 bits, the only difference comes when they have to be shown in screen, if the number is 65 and is saved as a char, then it will show 'A', if it's saved as a int it will show 65.
With other types things change, because they are stored differently in memory. There's standard function in C that allows you to convert from string to double easily, it's atof. (You need to include stdlib.h)
#include <stdlib.h>
int main()
{
string word;
openfile >> word;
double lol = atof(word.c_str()); /*c_str is needed to convert string to const char*
previously (the function requires it)*/
return 0;
}
In General a function to return string after substring is
function getStringAfterSubstring(parentString, substring) {_x000D_
return parentString.substring(parentString.indexOf(substring) + substring.length)_x000D_
}_x000D_
_x000D_
function getStringBeforeSubstring(parentString, substring) {_x000D_
return parentString.substring(0, parentString.indexOf(substring))_x000D_
}_x000D_
console.log(getStringAfterSubstring('abcxyz123uvw', '123'))_x000D_
console.log(getStringBeforeSubstring('abcxyz123uvw', '123'))
_x000D_
Just been working on something very similar, I am not an expert but I thought I would share the commands I have used. I had a multi column csv which I only required 4 columns out of and then I needed to reorder them.
My file was pipe '|' delimited but that can be swapped out.
LC_ALL=C cut -d$'|' -f1,2,3,8,10 ./file/location.txt | sed -E "s/(.*)\|(.*)\|(.*)\|(.*)\|(.*)/\3\|\5\|\1\|\2\|\4/" > ./newcsv.csv
Admittedly it is really rough and ready but it can be tweaked to suit!
As others already pointed out, a message box will be clientside Javascript. So the problem then is how to force a clientside JS message box from the server side. A simple solution is to include this in the HTML:
<script>
var data = '<%= JsData %>';
alert(data);
</script>
and to fill this data
from the server side code-behind:
public partial class PageName : Page
{
protected string JsData = "your message";
Note that the string value should be a Javascript string, i.e. be a one-liner, but it may contain escaped newlines as \n
.
Now you can use all your Javascript or JQuery skills and tricks to do whatever you want with that message text on the clientside, such as display a simple alert()
, as shown in the above code sample, or sophisticated message box or message banner.
(Note that popups are sometimes frowned upon and blocked)
Note also that, due to the HTTP protocol, the message can only be shown in response to an HTTP request that the user sends to the server. Unlike WinForm apps, the web server cannot push a message to the client whenever it sees fit.
If you want to show the message only once, and not after the user refreshes the page with F5, you could set and read a cookie with javascript code. In any case, the nice point with this method is that it is an easy way to get data from the server to the javascript on the client, and that you can use all javascript features to accomplish anything you like.
I like adding functions to jQuery so this function would help:
jQuery.fn.center = function () {
this.css("position","absolute");
this.css("top", Math.max(0, (($(window).height() - $(this).outerHeight()) / 2) +
$(window).scrollTop()) + "px");
this.css("left", Math.max(0, (($(window).width() - $(this).outerWidth()) / 2) +
$(window).scrollLeft()) + "px");
return this;
}
Now we can just write:
$(element).center();
Demo: Fiddle (with added parameter)
You can always do something shell-scripty like:
#!/usr/bin/node
var header = "Content-type: text/plain\n";
var hi = "Hello World from nodetest!";
console.log(header);
console.log(hi);
exit;
I had the same issue when I changed the home directory of one use. In my case it was because of selinux
. I used the below to fix the issue:
selinuxenabled 0
setenforce 0
The better of is to detect whether text will fits right before you display the element. So you can use this function which doesn't requires the element to be on screen.
function textWidth(text, fontProp) {
var tag = document.createElement("div");
tag.style.position = "absolute";
tag.style.left = "-999em";
tag.style.whiteSpace = "nowrap";
tag.style.font = fontProp;
tag.innerHTML = text;
document.body.appendChild(tag);
var result = tag.clientWidth;
document.body.removeChild(tag);
return result;
}
Usage:
if ( textWidth("Text", "bold 13px Verdana") > elementWidth) {
...
}
All above answers perfectly gives the solution to center the form using Bootstrap 4
. However, if someone wants to use out of the box Bootstrap 4
css classes without help of any additional styles and also not wanting to use flex
, we can do like this.
A sample form
HTML
<div class="container-fluid h-100 bg-light text-dark">
<div class="row justify-content-center align-items-center">

</div>
<hr/>

def is_iterable(x):
try:
0 in x
except TypeError:
return False
else:
return True
This will say yes to all manner of iterable objects, but it will say no to strings in Python 2. (That's what I want for example when a recursive function could take a string or a container of strings. In that situation, asking forgiveness may lead to obfuscode, and it's better to ask permission first.)
import numpy
class Yes:
def __iter__(self):
yield 1;
yield 2;
yield 3;
class No:
pass
class Nope:
def __iter__(self):
return 'nonsense'
assert is_iterable(Yes())
assert is_iterable(range(3))
assert is_iterable((1,2,3)) # tuple
assert is_iterable([1,2,3]) # list
assert is_iterable({1,2,3}) # set
assert is_iterable({1:'one', 2:'two', 3:'three'}) # dictionary
assert is_iterable(numpy.array([1,2,3]))
assert is_iterable(bytearray("not really a string", 'utf-8'))
assert not is_iterable(No())
assert not is_iterable(Nope())
assert not is_iterable("string")
assert not is_iterable(42)
assert not is_iterable(True)
assert not is_iterable(None)
Many other strategies here will say yes to strings. Use them if that's what you want.
import collections
import numpy
assert isinstance("string", collections.Iterable)
assert isinstance("string", collections.Sequence)
assert numpy.iterable("string")
assert iter("string")
assert hasattr("string", '__getitem__')
Note: is_iterable() will say yes to strings of type bytes
and bytearray
.
bytes
objects in Python 3 are iterable True == is_iterable(b"string") == is_iterable("string".encode('utf-8'))
There is no such type in Python 2.bytearray
objects in Python 2 and 3 are iterable True == is_iterable(bytearray(b"abc"))
The O.P. hasattr(x, '__iter__')
approach will say yes to strings in Python 3 and no in Python 2 (no matter whether ''
or b''
or u''
). Thanks to @LuisMasuelli for noticing it will also let you down on a buggy __iter__
.
It's a conceptual problem.
Stringstream is a stream, so its iterators are forward, cannot return. In an output stringstream, you need a flush() to reinitialize it, as in any other output stream.
Private Sub ListView1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView1.Click
Dim tt As String
tt = ListView1.SelectedItems.Item(0).SubItems(1).Text
TextBox1.Text = tt.ToString
End Sub
The following code the easiest way:
<h:outputLabel value="value = 10" rendered="#{row == 10}" />
<h:outputLabel value="value = 15" rendered="#{row == 15}" />
<h:outputLabel value="value xyz" rendered="#{row != 15 and row != 10}" />

You can use Number()
function also since it converts the object argument to a number that represents the object's value.

One of the many unnecessary complex things about Java making it unintuitive to use. Why instance variables are initialized with default 0 but local are not is not logical. Similar why enums dont have built in flag support and many more options. Java lambda is a nightmare compared to C# and not allowing class extension methods is also a big problem.
Java ecosystem comes up with excuses why its not possible but me as the user / developer i dont care about their excuses. I want easy approach and if they dont fix those things they will loose big in the future since C# and other languages are not waiting to make life of developers more simple. Its just sad to see the decline in the last 10 years since i work daily with Java.
I like to use: ArgumentException
, ArgumentNullException
, and ArgumentOutOfRangeException
.
ArgumentException
– Something is wrong with the argument.ArgumentNullException
– Argument is null.ArgumentOutOfRangeException
– I don’t use this one much, but a common use is indexing into a collection, and giving an index which is to large.There are other options, too, that do not focus so much on the argument itself, but rather judge the call as a whole:
InvalidOperationException
– The argument might be OK, but not in the current state of the object. Credit goes to STW (previously Yoooder). Vote his answer up as well.NotSupportedException
– The arguments passed in are valid, but just not supported in this implementation. Imagine an FTP client, and you pass a command in that the client doesn’t support.The trick is to throw the exception that best expresses why the method cannot be called the way it is. Ideally, the exception should be detailed about what went wrong, why it is wrong, and how to fix it.
I love when error messages point to help, documentation, or other resources. For example, Microsoft did a good first step with their KB articles, e.g. “Why do I receive an "Operation aborted" error message when I visit a Web page in Internet Explorer?”. When you encounter the error, they point you to the KB article in the error message. What they don’t do well is that they don’t tell you, why specifically it failed.
Thanks to STW (ex Yoooder) again for the comments.
In response to your followup, I would throw an ArgumentOutOfRangeException
. Look at what MSDN says about this exception:
ArgumentOutOfRangeException
is thrown when a method is invoked and at least one of the arguments passed to the method is not null reference (Nothing
in Visual Basic) and does not contain a valid value.
So, in this case, you are passing a value, but that is not a valid value, since your range is 1–12. However, the way you document it makes it clear, what your API throws. Because although I might say ArgumentOutOfRangeException
, another developer might say ArgumentException
. Make it easy and document the behavior.
This is just an Improvement of @soulcheck 's answer, and fix of the typo in forEach (missing closing bracket);

Try adding System.Web
as a reference to your project.
Hashing is a one-way process but using a password-list you can regenerate the hashes and compare to the stored hash to 'crack' the password.
This site https://crackstation.net/ attempts to do this for you - run through passwords lists and tell you the cleartext password based on your hash.
Really, the only use of typedef that carries over to Javaland is aliasing- that is, giving the same class multiple names. That is, you've got a class "A" and you want "B" to refer to the same thing. In C++, you'd be doing "typedef B A;"
Unfortunately, they just don't support it. However, if you control all the types involved you CAN pull a nasty hack at the library level- you either extend B from A or have B implement A.
How about
(from k in myList
where k.id > 35
select k).ToList().ForEach(k => k.Name = "Banana");

Your bytes
object is almost JSON, but it's using single quotes instead of double quotes, and it needs to be a string. So one way to fix it is to decode the bytes
to str
and replace the quotes. Another option is to use ast.literal_eval
; see below for details. If you want to print the result or save it to a file as valid JSON you can load the JSON to a Python list and then dump it out. Eg,
import json
my_bytes_value = b'[{\'Date\': \'2016-05-21T21:35:40Z\', \'CreationDate\': \'2012-05-05\', \'LogoType\': \'png\', \'Ref\': 164611595, \'Classe\': [\'Email addresses\', \'Passwords\'],\'Link\':\'http://some_link.com\'}]'
# Decode UTF-8 bytes to Unicode, and convert single quotes
# to double quotes to make it valid JSON
my_json = my_bytes_value.decode('utf8').replace("'", '"')
print(my_json)
print('- ' * 20)
# Load the JSON to a Python list & dump it back out as formatted JSON
data = json.loads(my_json)
s = json.dumps(data, indent=4, sort_keys=True)
print(s)
output
[{"Date": "2016-05-21T21:35:40Z", "CreationDate": "2012-05-05", "LogoType": "png", "Ref": 164611595, "Classe": ["Email addresses", "Passwords"],"Link":"http://some_link.com"}]
- - - - - - - - - - - - - - - - - - - -
[
{
"Classe": [
"Email addresses",
"Passwords"
],
"CreationDate": "2012-05-05",
"Date": "2016-05-21T21:35:40Z",
"Link": "http://some_link.com",
"LogoType": "png",
"Ref": 164611595
}
]
As Antti Haapala mentions in the comments, we can use ast.literal_eval
to convert my_bytes_value
to a Python list, once we've decoded it to a string.
from ast import literal_eval
import json
my_bytes_value = b'[{\'Date\': \'2016-05-21T21:35:40Z\', \'CreationDate\': \'2012-05-05\', \'LogoType\': \'png\', \'Ref\': 164611595, \'Classe\': [\'Email addresses\', \'Passwords\'],\'Link\':\'http://some_link.com\'}]'
data = literal_eval(my_bytes_value.decode('utf8'))
print(data)
print('- ' * 20)
s = json.dumps(data, indent=4, sort_keys=True)
print(s)
Generally, this problem arises because someone has saved data by printing its Python repr
instead of using the json
module to create proper JSON data. If it's possible, it's better to fix that problem so that proper JSON data is created in the first place.

You can use System.Uri
Uri url = new Uri("http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye");
string path = String.Format("{0}{1}{2}{3}", url.Scheme,
Uri.SchemeDelimiter, url.Authority, url.AbsolutePath);
Or you can use substring
string url = "http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye";
string path = url.Substring(0, url.IndexOf("?"));

Just use toDateString() on both dates. toDateString doesn't include the time, so for 2 times on the same date, the values will be equal, as demonstrated below.

var d2 = new Date(2019,01,01,2,20)
console.log(d1==d2) // false
console.log(d1.toDateString() == d2.toDateString()) // true

Callbacks are most easily described in terms of the telephone system. A function call is analogous to calling someone on a telephone, asking her a question, getting an answer, and hanging up; adding a callback changes the analogy so that after asking her a question, you also give her your name and number so she can call you back with the answer.

There are few steps if we dont use "create-react-app",([email protected]) first we should install file-loader as devDedepencie,next step is to add rule in webpack.config
{
test: /\.(png|jpe?g|gif)$/i,
loader: 'file-loader',
}
_x000D_
, then in our src directory we should make file called declarationFiles.d.ts(for example) and register modules inside
declare module '*.jpg';
declare module '*.png';
_x000D_
,then restart dev-server. After these steps we can import and use images like in code bellow
import React from 'react';
import image from './img1.png';
import './helloWorld.scss';
const HelloWorld = () => (
<>
<h1 className="main">React TypeScript Starter</h1>
<img src={image} alt="some example image" />
</>
);
export default HelloWorld;

GitHub Fix Docker Daemon Crash
I changed the content of my docker-compose-deps.yml file as seen in the link. Then I ran docker-compose -f docker-compose-deps.yml up -d

Actually, usecase for template template parameters is rather obvious. Once you learn that C++ stdlib has gaping hole of not defining stream output operators for standard container types, you would proceed to write something like:
template<typename T>
static inline std::ostream& operator<<(std::ostream& out, std::list<T> const& v)
{
out << '[';
if (!v.empty()) {
for (typename std::list<T>::const_iterator i = v.begin(); ;) {
out << *i;
if (++i == v.end())
break;
out << ", ";
}
}
out << ']';
return out;
}
Then you'd figure out that code for vector is just the same, for forward_list is the same, actually, even for multitude of map types it's still just the same. Those template classes don't have anything in common except for meta-interface/protocol, and using template template parameter allows to capture the commonality in all of them. Before proceeding to write a template though, it's worth to check a reference to recall that sequence containers accept 2 template arguments - for value type and allocator. While allocator is defaulted, we still should account for its existence in our template operator<<:
template<template <typename, typename> class Container, class V, class A>
std::ostream& operator<<(std::ostream& out, Container<V, A> const& v)
...
Voila, that will work automagically for all present and future sequence containers adhering to the standard protocol. To add maps to the mix, it would take a peek at reference to note that they accept 4 template params, so we'd need another version of the operator<< above with 4-arg template template param. We'd also see that std:pair tries to be rendered with 2-arg operator<< for sequence types we defined previously, so we would provide a specialization just for std::pair.
Btw, with C+11 which allows variadic templates (and thus should allow variadic template template args), it would be possible to have single operator<< to rule them all. For example:
#include <iostream>
#include <vector>
#include <deque>
#include <list>
template<typename T, template<class,class...> class C, class... Args>
std::ostream& operator <<(std::ostream& os, const C<T,Args...>& objs)
{
os << __PRETTY_FUNCTION__ << '\n';
for (auto const& obj : objs)
os << obj << ' ';
return os;
}
int main()
{
std::vector<float> vf { 1.1, 2.2, 3.3, 4.4 };
std::cout << vf << '\n';
std::list<char> lc { 'a', 'b', 'c', 'd' };
std::cout << lc << '\n';
std::deque<int> di { 1, 2, 3, 4 };
std::cout << di << '\n';
return 0;
}
Output
std::ostream &operator<<(std::ostream &, const C<T, Args...> &) [T = float, C = vector, Args = <std::__1::allocator<float>>]
1.1 2.2 3.3 4.4
std::ostream &operator<<(std::ostream &, const C<T, Args...> &) [T = char, C = list, Args = <std::__1::allocator<char>>]
a b c d
std::ostream &operator<<(std::ostream &, const C<T, Args...> &) [T = int, C = deque, Args = <std::__1::allocator<int>>]

In .Net through version 4 this can be done the same way as for SQL Server Stored Procs but note that you need:
using System.Data.OracleClient;
There are some system requirements here that you should verify are OK in your scenario.
Microsoft is deprecating this namespace as of .Net 4 so third-party providers will be needed in the future. With this in mind, you may be better off using Oracle Data Provider for .Net (ODP.NET) from the word go - this has optimizations that are not in the Microsoft classes. There are other third-party options, but Oracle has a strong vested interest in keeping .Net developers on board so theirs should be good.
You can revert all your files under your working directory and index by typing following this command

Turn on gzip if you want to do it properly. You can also just do something like this:
$this->output = preg_replace(

'/<!--.*?-->|\t|(?:\r?\n[ \t]*)+/s'
),
array(
' ',
''
),
$this->output
);

One option to override CSS class in JavaScript is using an ID for the style element so that we can update the CSS class
function writeStyles(styleName, cssText) {
var styleElement = document.getElementById(styleName);
if (styleElement) document.getElementsByTagName('head')[0].removeChild(
styleElement);
styleElement = document.createElement('style');
styleElement.type = 'text/css';
styleElement.id = styleName;
styleElement.innerHTML = cssText;
document.getElementsByTagName('head')[0].appendChild(styleElement);
}
..
var cssText = '.testDIV{ height:' + height + 'px !important; }';
writeStyles('styles_js', cssText)
If you have two values yanked into two different registers (for example register a
and register b
) then you can simply set a variable c
and do the operation on it.
For example, :set c = str2float(@a) + str2float(@b)
and then you can paste the content of c
anywhere.
For example whilst in INSERT mode, CTRL + R
then type =
to enter into the expression register and just type c
after equal sign and hit ENTER. Done you should now have the total of a
and b
registers.
All these can be recorded in a macro and repeated over!
The str2float
function is used if you are working with floats, if you don't, you will get integers instead.
I am not sure if this is idiomatic but it worked for my case where I needed to add 2 numbers in a row and repeat it for 500 more lines.
If you want to pause then use java.util.concurrent.TimeUnit
:
TimeUnit.SECONDS.sleep(1);
To sleep for one second or
TimeUnit.MINUTES.sleep(1);
To sleep for a minute.
As this is a loop, this presents an inherent problem - drift. Every time you run code and then sleep you will be drifting a little bit from running, say, every second. If this is an issue then don't use sleep
.
Further, sleep
isn't very flexible when it comes to control.
For running a task every second or at a one second delay I would strongly recommend a ScheduledExecutorService
and either scheduleAtFixedRate
or scheduleWithFixedDelay
.
For example, to run the method myTask
every second (Java 8):
public static void main(String[] args) {
final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
executorService.scheduleAtFixedRate(App::myTask, 0, 1, TimeUnit.SECONDS);
}
private static void myTask() {
System.out.println("Running");
}
And in Java 7:
public static void main(String[] args) {
final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
executorService.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
myTask();
}
}, 0, 1, TimeUnit.SECONDS);
}
private static void myTask() {
System.out.println("Running");
}

I developed an extension for this purpose, so you can easily put a decorator on your view function and see how many queries are executed.
To install:
$ pip install django-print-sql
To use as context manager:
from django_print_sql import print_sql
# set `count_only` to `True` will print the number of executed SQL statements only
with print_sql(count_only=False):
# write the code you want to analyze in here,
# e.g. some complex foreign key lookup,
# or analyzing a DRF serializer's performance
for user in User.objects.all()[:10]:
user.groups.first()
To use as decorator:
from django_print_sql import print_sql_decorator
@print_sql_decorator(count_only=False) # this works on class-based views as well
def get(request):
# your view code here
you can make a shell script with those commands, and then chmod +x <scriptname.sh>

For activity indicator, its better you create one custom class.
Instead of creating UIActivityIndicator in each UIViewController.Subclass UIView and use from any UIViewController.
Updated for Swift 5.0:
import UIKit
import Foundation
class ProgressIndicator: UIView {
var indicatorColor:UIColor
var loadingViewColor:UIColor
var loadingMessage:String
var messageFrame = UIView()
var activityIndicator = UIActivityIndicatorView()
init(inview:UIView,loadingViewColor:UIColor,indicatorColor:UIColor,msg:String){
self.indicatorColor = indicatorColor
self.loadingViewColor = loadingViewColor
self.loadingMessage = msg
super.init(frame: CGRect(x: inview.frame.midX - 90, y: inview.frame.midY - 250 , width: 180, height: 50))
initalizeCustomIndicator()
}
convenience init(inview:UIView) {
self.init(inview: inview,loadingViewColor: UIColor.brown,indicatorColor:UIColor.black, msg: "Loading..")
}
convenience init(inview:UIView,messsage:String) {
self.init(inview: inview,loadingViewColor: UIColor.brown,indicatorColor:UIColor.black, msg: messsage)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func initalizeCustomIndicator(){
messageFrame.frame = self.bounds
activityIndicator = UIActivityIndicatorView(style: UIActivityIndicatorView.Style.medium)
activityIndicator.tintColor = indicatorColor
activityIndicator.hidesWhenStopped = true
activityIndicator.frame = CGRect(x: self.bounds.origin.x + 6, y: 0, width: 20, height: 50)
print(activityIndicator.frame)
let strLabel = UILabel(frame:CGRect(x: self.bounds.origin.x + 30, y: 0, width: self.bounds.width - (self.bounds.origin.x + 30) , height: 50))
strLabel.text = loadingMessage
strLabel.adjustsFontSizeToFitWidth = true
strLabel.textColor = UIColor.white
messageFrame.layer.cornerRadius = 15
messageFrame.backgroundColor = loadingViewColor
messageFrame.alpha = 0.8
messageFrame.addSubview(activityIndicator)
messageFrame.addSubview(strLabel)
}
func start(){
//check if view is already there or not..if again started
if !self.subviews.contains(messageFrame){
activityIndicator.startAnimating()
self.addSubview(messageFrame)
}
}
func stop(){
if self.subviews.contains(messageFrame){
activityIndicator.stopAnimating()
messageFrame.removeFromSuperview()
}
}
}
Put this class in your project and then call from any ViewController as
var indicator:ProgressIndicator?
override func viewDidLoad() {
super.viewDidLoad()
//indicator = ProgressIndicator(inview: self.view,messsage: "Hello from Nepal..")
//self.view.addSubview(indicator!)
//OR
indicator = ProgressIndicator(inview:self.view,loadingViewColor: UIColor.grayColor(), indicatorColor: UIColor.blackColor(), msg: "Landing within minutes,Please hold tight..")
self.view.addSubview(indicator!)
}
@IBAction func startBtn(sender: AnyObject) {
indicator!.start()
}
@IBAction func stopBtn(sender: AnyObject) {
indicator!.stop()
}
import org.apache.commons.lang3.StringUtils;
// path = "http://cdn.gs.com/new/downloads/Q22010MVR_PressRelease.pdf.null"
StringUtils.removeEnd(path, ".null");
// path = "http://cdn.gs.com/new/downloads/Q22010MVR_PressRelease.pdf"
no need for the padding or the corners.
here's a sample:

<gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
android:angle="270"/>
</shape>
based on :
static means local for compilation unit (i.e. a single C++ source code file), or in other words it means it is not added to a global namespace. you can have multiple static variables in different c++ source code files with the same name and no name conflicts.
const is just constant, meaning can't be modified.
Maybe your model not linked when migration process is ongoing.
Try to import it in file urls.py
from models import your_file
Give it an ID like "something", then:
var something = document.getElementById('something');
something.style.cursor = 'pointer';
something.onclick = function() {
// do something...
};
Changing the background color (as per your updated question):
something.onmouseover = function() {
this.style.backgroundColor = 'red';
};
something.onmouseout = function() {
this.style.backgroundColor = '';
};
cat dump.txt | head -16224 | tail -258
should do the trick. The downside of this approach is that you need to do the arithmetic to determine the argument for tail and to account for whether you want the 'between' to include the ending line or not.

replace -> replaces the div

Add an EditText on top of your listview in its .xml layout file. And in your activity/fragment..
lv = (ListView) findViewById(R.id.list_view);
inputSearch = (EditText) findViewById(R.id.inputSearch);
// Adding items to listview
adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.product_name, products);
lv.setAdapter(adapter);
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changed the Text
MainActivity.this.adapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { }
@Override
public void afterTextChanged(Editable arg0) {}
});
The basic here is to add an OnTextChangeListener to your edit text and inside its callback method apply filter to your listview's adapter.
EDIT
To get filter to your custom BaseAdapter you"ll need to implement Filterable interface.
class CustomAdapter extends BaseAdapter implements Filterable {
public View getView(){
...
}
public Integer getCount()
{
...
}
@Override
public Filter getFilter() {
Filter filter = new Filter() {
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
arrayListNames = (List<String>) results.values;
notifyDataSetChanged();
}
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
ArrayList<String> FilteredArrayNames = new ArrayList<String>();
// perform your search here using the searchConstraint String.
constraint = constraint.toString().toLowerCase();
for (int i = 0; i < mDatabaseOfNames.size(); i++) {
String dataNames = mDatabaseOfNames.get(i);
if (dataNames.toLowerCase().startsWith(constraint.toString())) {
FilteredArrayNames.add(dataNames);
}
}
results.count = FilteredArrayNames.size();
results.values = FilteredArrayNames;
Log.e("VALUES", results.values.toString());
return results;
}
};
return filter;
}
}
Inside performFiltering() you need to do actual comparison of the search query to values in your database. It will pass its result to publishResults() method.
using Array#some
and Object.keys
. It will return true if given key exists in the object or false if it doesn't.

Use defaultValue and onChange like this
const [myValue, setMyValue] = useState('');
<select onChange={(e) => setMyValue(e.target.value)} defaultValue={props.myprop}>
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</select>
Ideally the background property would allow us to layer various backgrounds similar to the background image layering detailed at http://www.css3.info/preview/multiple-backgrounds/. Unfortunately, at least in Chrome (40.0.2214.115), adding an rgba background alongside a url() image background seems to break the property.
The solution I've found is to render the rgba layer as a 1px*1px Base64 encoded image and inline it.
.the-div:hover {
background-image:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mNgkAQAABwAGkn5GOoAAAAASUVORK5CYII=), url("the-image.png");
}
for base64 encoded 1*1 pixel images I used http://px64.net/
Here is your jsfiddle with these changes made. http://jsfiddle.net/325Ft/49/ (I also swapped the image to one that still exists on the internet)
I made my own way based on Caitlin Morris's answer for fetching all folowers and followings on Instagram. Just copy this code, paste in browser console and wait for a few seconds.
You need to use browser console from instagram.com tab to make it works.
let username = 'USERNAME'
let followers = [], followings = []
try {
let res = await fetch(`https://www.instagram.com/${username}/?__a=1`)
res = await res.json()
let userId = res.graphql.user.id
let after = null, has_next = true
while (has_next) {
await fetch(`https://www.instagram.com/graphql/query/?query_hash=c76146de99bb02f6415203be841dd25a&variables=` + encodeURIComponent(JSON.stringify({
id: userId,
include_reel: true,
fetch_mutual: true,
first: 50,
after: after
}))).then(res => res.json()).then(res => {
has_next = res.data.user.edge_followed_by.page_info.has_next_page
after = res.data.user.edge_followed_by.page_info.end_cursor
followers = followers.concat(res.data.user.edge_followed_by.edges.map(({node}) => {
return {
username: node.username,
full_name: node.full_name
}
}))
})
}
console.log('Followers', followers)
has_next = true
after = null
while (has_next) {
await fetch(`https://www.instagram.com/graphql/query/?query_hash=d04b0a864b4b54837c0d870b0e77e076&variables=` + encodeURIComponent(JSON.stringify({
id: userId,
include_reel: true,
fetch_mutual: true,
first: 50,
after: after
}))).then(res => res.json()).then(res => {
has_next = res.data.user.edge_follow.page_info.has_next_page
after = res.data.user.edge_follow.page_info.end_cursor
followings = followings.concat(res.data.user.edge_follow.edges.map(({node}) => {
return {
username: node.username,
full_name: node.full_name
}
}))
})
}
console.log('Followings', followings)
} catch (err) {
console.log('Invalid username')
}
You can use:
$(window).unload(function() {
//do something
}
Unload() is deprecated in jQuery version 1.8, so if you use jQuery > 1.8 you can use even beforeunload instead.
The beforeunload event fires whenever the user leaves your page for any reason.
$(window).on("beforeunload", function() {
return confirm("Do you really want to close?");
})
Source Browser window close event
To simply repeat the same letter 10 times:
string_val = "x" * 10 # gives you "xxxxxxxxxx"
And if you want something more complex, like n
random lowercase letters, it's still only one line of code (not counting the import statements and defining n
):
from random import choice
from string import ascii_lowercase
n = 10
string_val = "".join(choice(ascii_lowercase) for i in range(n))
With PowerShell 5.1 in Windows 10 you can use:
Get-SmbMapping | Remove-SmbMapping -Confirm:$false
i made a column by name : update-at in phpMyAdmin and got the current time from Date() method in my code (nodejs) . with every change in table this column hold the time of changes.
For people who are reading byte array into String and trying to convert to object with JAXB, you can add "iso-8859-1" encoding by creating String from byte array like this:
String JAXBallowedString= new String(byte[] input, "iso-8859-1");
This would replace the conflicting byte to single-byte encoding which JAXB can handle. Obviously this solution is only to parse the xml.
I had this problem today. I fixed it being being explict about my require
gem 'uglifier', '>= 1.0.3', require: 'uglifier'
I had mine still in the assets group.
Select [Column Name] into [New Table] from [Source Table]
dir /ad /b /s
will give the required answer.
I think you wanted to do this:
while( $row = mysql_fetch_assoc( $result)){
$new_array[] = $row; // Inside while loop
}
Or maybe store id as key too
$new_array[ $row['id']] = $row;
Using the second ways you would be able to address rows directly by their id, such as: $new_array[ 5]
.
I got the same error. I have been using select2-3.5.2
This was my code which had error
$('#carstatus-select').select2().val([1,2])
Below code fixed the issue.
$('#carstatus-select').val([1,2]);
String[] str = new String[0];
?
String str = "Good";
str = str + " Morning";
In the above code you create 3 String
Objects.
Note: Strings are always immutable. There is no, such thing as a mutable String. str
is just a reference which eventually points to "Good Morning". You are actually, not working on 1
object. you have 3
distinct String
Objects.
StringBuffer str = new StringBuffer("Good");
str.append(" Morning");
StringBuffer
contains an array of characters. It is not same as a String
.
The above code adds characters to the existing array. Effectively, StringBuffer
is mutable, its String
representation isn't.
Always try to remember these three content types even though there are many content types. as you may have to use these more frequently.
I used Dynamic Programming & Memoization to find count of subsets from a set having a particular total. The code below code is in java. Have included the comments to explain the code intentions -
package com.company.dynamicProgramming;
import java.util.HashMap;
import java.util.Map;
import java.util.Objects;
public class FindSumInSubSet {
public static void main(String...args){
int[] arr = {3, 2, 4, 6, 10};
int total = 16;
// Challenge is to find the subsets of numbers total 6 in above super set (represented as array)
// In general - Write a code to count subset of elements totalling m(6 above) in given set of n(9 as array size above) elements
Map<Entry, Integer> memoMap = new HashMap<>();
Entry entry = new Entry(total, arr.length-1);
int count = countSubSetForSum(arr, entry, memoMap);
System.out.format("In set of %d elements, the number of subsets having total=%d is %d %n", arr.length,total, count);
}
static int countSubSetForSum(int[] arr, Entry entry, Map<Entry, Integer> memoMap){
int total = entry.getTotal();
int i = entry.getI();
if (total == 0){ // means element was equal in previous recursion
return 1;
}else if(total < 0){ // means element was less in previous recursion i.e. not equal
return 0;
}else if (i < 0){ // means arr was finished previous recursion
return 0;
}else if (arr[i] > total){ // means element is greater than total
// i.e. leave that element and look further sets excluding this element
return getCountForIthAndTotal(arr, new Entry( total, i-1), memoMap);
}else{ // means element is less than total i.e. 2 possibilities :
// 1st - look further sets including this element
// 2nd - look further sets excluding this element
return getCountForIthAndTotal(arr, new Entry( total-arr[i], i-1), memoMap) +
getCountForIthAndTotal(arr, new Entry( total, i-1), memoMap);
}
}
static int getCountForIthAndTotal(int[] arr, Entry entry, Map<Entry, Integer> memoMap){
if (memoMap.containsKey(entry)){ //look up in has table if we already calculated particular total for ith subset..
return memoMap.get(entry); //This is nothing but using memoization that reduce the entire below code i.e. further recursion -
}else {
int count = countSubSetForSum(arr, entry, memoMap); //Recursion
memoMap.put(entry, count); //Build memoization
return count;
}
}
//Just Data Structure for Key in HashMap (memoMaP)... intent to include particular total for ith element's subset.
static class Entry {
int total;
int i;
public Entry(int total, int i) {
this.total = total;
this.i = i;
}
public int getTotal() {
return total;
}
public int getI() {
return i;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Entry entry = (Entry) o;
return total == entry.total &&
i == entry.i;
}
@Override
public int hashCode() {
return Objects.hash(total, i);
}
}
}
When i ran this the out put is :
In set of 5 elements, the number of subsets having total=16 is 2
Process finished with exit code 0
For all users on a specific database, do the following:
# psql
\c your_database
select grantee, table_catalog, privilege_type, table_schema, table_name from information_schema.table_privileges order by grantee, table_schema, table_name;
New answer:
In HTML5 you can add the multiple
attribute to select more than 1 file.
<input type="file" name="filefield" multiple="multiple">
Old answer:
You can only select 1 file per
<input type="file" />
. If you want to send multiple files you will have to use multiple input tags or use Flash or Silverlight.
$('#input').on('keyup', function() {
var RegExpression = /^[a-zA-Z\s]*$/;
...
});
\s
will allow the space
If your html link is like this:
<a class ="linkClass" href="https://stackoverflow.com/"> Stack Overflow</a>
Then you can access the href in jquery as given below (there is no need to use "a" in href for this)
$(".linkClass").on("click",accesshref);
function accesshref()
{
var url = $(".linkClass").attr("href");
//OR
var url = $(this).attr("href");
}
How to do a redirect to another route with react-router?
For example, when a user clicks a link <Link to="/" />Click to route</Link>
react-router will look for /
and you can use Redirect to
and send the user somewhere else like the login route.
From the docs for ReactRouterTraining:
Rendering a
<Redirect>
will navigate to a new location. The new location will override the current location in the history stack, like server-side redirects (HTTP 3xx) do.
import { Route, Redirect } from 'react-router'
<Route exact path="/" render={() => (
loggedIn ? (
<Redirect to="/dashboard"/>
) : (
<PublicHomePage/>
)
)}/>
to: string, The URL to redirect to.
<Redirect to="/somewhere/else"/>
to: object, A location to redirect to.
<Redirect to={{
pathname: '/login',
search: '?utm=your+face',
state: { referrer: currentLocation }
}}/>
Another example which uses function in ref rather than string
class List extends React.Component {
constructor(props) {
super(props);
this.state = { items:[], index: 0 };
this._nodes = new Map();
this.handleAdd = this.handleAdd.bind(this);
this.handleRemove = this.handleRemove.bind(this);
}
handleAdd() {
let startNumber = 0;
if (this.state.items.length) {
startNumber = this.state.items[this.state.items.length - 1];
}
let newItems = this.state.items.splice(0);
for (let i = startNumber; i < startNumber + 100; i++) {
newItems.push(i);
}
this.setState({ items: newItems });
}
handleRemove() {
this.setState({ items: this.state.items.slice(1) });
}
handleShow(i) {
this.setState({index: i});
const node = this._nodes.get(i);
console.log(this._nodes);
if (node) {
ReactDOM.findDOMNode(node).scrollIntoView({block: 'end', behavior: 'smooth'});
}
}
render() {
return(
<div>
<ul>{this.state.items.map((item, i) => (<Item key={i} ref={(element) => this._nodes.set(i, element)}>{item}</Item>))}</ul>
<button onClick={this.handleShow.bind(this, 0)}>0</button>
<button onClick={this.handleShow.bind(this, 50)}>50</button>
<button onClick={this.handleShow.bind(this, 99)}>99</button>
<button onClick={this.handleAdd}>Add</button>
<button onClick={this.handleRemove}>Remove</button>
{this.state.index}
</div>
);
}
}
class Item extends React.Component
{
render() {
return (<li ref={ element => this.listItem = element }>
{this.props.children}
</li>);
}
}
There is also http://appyframework.org/pod.html which takes a LibreOffice or OpenOffice document as template and can generate pdf, rtf, odt ... To generate pdf it requires a headless OOo on some server. Documentation is concise but relatively complete. http://appyframework.org/podWritingTemplates.html If you need advice, the author is rather helpful.
String.Format("X", c);
That just outputs: X
Try this instead:
string t = ((int)c).ToString("X");
sb.Append("\\u" + t.PadLeft(4, '0'));
You can have a pair of extension methods to make this task easier:
public static string ToDelimitedString<T>(this IEnumerable<T> lst, string separator = ", ")
{
return lst.ToDelimitedString(p => p, separator);
}
public static string ToDelimitedString<S, T>(this IEnumerable<S> lst, Func<S, T> selector,
string separator = ", ")
{
return string.Join(separator, lst.Select(selector));
}
So now just:
new int[] { 1, 2, 3, 4, 5 }.ToDelimitedString();

I would also advise longer term to consider a limited rights domain user, what you are trying works fine in a silo machine scenario but you are going to have to make changes if you move to another machine for the DB server.
It turns out I was missing the header information. The following works:
url = "http://localhost:8080"
data = {'sender': 'Alice', 'receiver': 'Bob', 'message': 'We did it!'}
headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
r = requests.post(url, data=json.dumps(data), headers=headers)
A = zeros(20, 10, 3); %# Creates a 20x10x3 matrix
B = zeros(4,4);
C = zeros(size(B,1), size(B,2), 4); %# New matrix with B's size, and 3rd dimension of size 4
C(:,:,1) = B; %# Copy the content of B into C's first set of values
zeros is just one way of making a new matrix. Another could be A(1:20,1:10,1:3) = 0
for a 3D matrix. To confirm the size of your matrices you can run: size(A)
which gives 20 10 3
.
There is no explicit bound on the number of dimensions a matrix may have.
I think you are confusing the working mechanisms between int()
and round()
.
int()
always truncates the decimal numbers if a floating number is given; whereas round()
, in case of 2.5
where 2
and 3
are both within equal distance from 2.5
, Python returns whichever that is more away from the 0 point.
round(2.5) = 3
int(2.5) = 2
The solution provided by Emanuele worked for me. I could see the report when I accessed it directly from the server but when I used a ReportViewer control on my aspx page, I was unable to see the report. Upon inspecting the rendered HTML, I found a div by the id "ReportViewerGeneral_ctl09" (ReportViewerGeneral is the server id of the report viewer control) which had it's overflow property set to auto.
<div id="ReportViewerGeneral_ctl09" style="height: 100%; width: 100%; overflow: auto; position: relative; ">...</div>
I used the procedure explained by Emanuele to change this to visible as follows:
function pageLoad() {
var element = document.getElementById("ReportViewerGeneral_ctl09");
if (element) {
element.style.overflow = "visible";
}
}
This will work fast:
Case 1 - File2 = File1 + extra text appended.
grep -Fxvf File2.txt File1.txt >> File3.txt
File 1: 80 Lines File 2: 100 Lines File 3: 20 Lines
You need to escape the "
so that PHP doesn't recognise them as part of your PHP code. You do this by using the \
escape character.
So, your code would look like this:
echo
"<div>
<h3><a href=\"#\">First</a></h3>
<div>Lorem ipsum dolor sit amet.</div>
</div>
<div>"
For those who are still trying, this link helped me out, too; it just puts it all together:
http://dotnetslackers.com/VB_NET/re-36138_How_To_Get_Selected_Date_from_MonthCalendar_control.aspx
private void MonthCalendar1_DateChanged(object sender, System.Windows.Forms.DateRangeEventArgs e)
{
//Display the dates for selected range
Label1.Text = "Dates Selected from :" + (MonthCalendar1.SelectionRange.Start() + " to " + MonthCalendar1.SelectionRange.End);
//To display single selected of date
//MonthCalendar1.MaxSelectionCount = 1;
//To display single selected of date use MonthCalendar1.SelectionRange.Start/ MonthCalendarSelectionRange.End
Label2.Text = "Date Selected :" + MonthCalendar1.SelectionRange.Start;
}

In App\Http\Middleware\RedirectIfAuthenticated change redirect('/home')
to redirect()->intended('/home')
in the handle function:
public function handle($request, Closure $next, $guard = null)
{
if (Auth::guard($guard)->check()) {
return redirect()->intended('/home');
}
return $next($request);
}
in App\Http\Controllers\Auth\LoginController create the showLoginForm()
function as follows:
public function showLoginForm()
{
if(!session()->has('url.intended'))
{
session(['url.intended' => url()->previous()]);
}
return view('auth.login');
}
This way if there was an intent for another page it will redirect there otherwise it will redirect home.
If you want to output your structure into a file there is no need to convert any value beforehand. You can just use the printf format specification to indicate how to output your values and use any of the operators from printf family to output your data.
If you need to clean out all data, it might be faster to recreate collection, e.g.
solrctl --zk localhost:2181/solr collection --delete <collectionName>
solrctl --zk localhost:2181/solr collection --create <collectionName> -s 1
save the file on your disk and then use the following as URL:
file://your_path/your_file.wsdl

import pymongo
conn = pymongo.MongoClient()
db = conn.test #test is my database
col = db.spam #Here spam is my collection
array = list(col.find())
print array

I found it, I was trying to compile my app which is using facebook sdk. I was made that like augst 2016. When I try to open it today i got same error. I had that line in my gradle " compile 'com.facebook.android:facebook-android-sdk:4.+' " and I went https://developers.facebook.com/docs/android/change-log-4x this page and i found the sdk version while i was running this app succesfully and it was 4.14.1 then I changed that line to " compile 'com.facebook.android:facebook-android-sdk:4.14.1' " and it worked.
First we grab the command output, then wrap it and select one of its properties. There is only one and its "Name" which is what we want. So we select the groups property with ".name" then output it.

You can use the function below which replaces the first occurrence of the word from right.
def replace_from_right(text: str, original_text: str, new_text: str) -> str:

return text[::-1].replace(original_text[::-1], new_text[::-1], 1)[::-1]
A trick that works is to position box #2 with position: absolute
instead of position: relative
. We usually put a position: relative
on an outer box (here box #2) when we want an inner box (here box #3) with position: absolute
to be positioned relative to the outer box. But remember: for box #3 to be positioned relative to box #2, box #2 just need to be positioned. With this change, we get:
And here is the full code with this change:

The proper way to do it is probably to break down the method by putting the try-catch block in a separate method, and use a return statement:
public void someMethod() {
try {
...
if (condition)
return;
...
} catch (SomeException e) {
...
}
}
If the code involves lots of local variables, you may also consider using a break
from a labeled block, as suggested by Stephen C:
label: try {
...
if (condition)
break label;
...
} catch (SomeException e) {
...
}
Consider changing your markup to this:
<span id="someId">onlineff</span>
Then you can use this script:
var x = document.getElementById('someId');
x.style.color = '#00FF00';

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

SQL tables are not ordered by default, and asking for the n-th row from a non ordered set of rows has no meaning as it could potentially return a different row each time unless you specify an ORDER BY:
select * from customer order by id where row_number() = 3
(sometimes MySQL tables are shown with an internal order but you cannot rely on this behaviour). Then you can use LIMIT offset, row_count
, with a 0-based offset so row number 3 becomes offset 2:
select * from customer order by id
limit 2, 1
or you can use LIMIT row_count OFFSET offset
:
select * from customer order by id
limit 1 offset 2
Have a look at the documentation for -[UIStoryboard instantiateViewControllerWithIdentifier:]
. This allows you to instantiate a view controller from your storyboard using the identifier that you set in the IB Attributes Inspector:
EDITED to add example code:
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard"
bundle: nil];
MyViewController *controller = (MyViewController*)[mainStoryboard
instantiateViewControllerWithIdentifier: @"<Controller ID>"];
That is the mode with which you are opening the file. "wb" means that you are writing to the file (w), and that you are writing in binary mode (b).
Check out the documentation for more: clicky
If you use %pylab inline
you can (on a new line) insert the following command:
%pylab inline
pylab.rcParams['figure.figsize'] = (10, 6)
This will set all figures in your document (unless otherwise specified) to be of the size (10, 6)
, where the first entry is the width and the second is the height.

In General to get rid of
Object of class stdClass could not be converted to string.
try to use echo '<pre>'; print_r($sql_query);
for my SQL Query got the result as
stdClass Object
(
[num_rows] => 1
[row] => Array
(
[option_id] => 2
[type] => select
[sort_order] => 0
)
[rows] => Array
(
[0] => Array
(
[option_id] => 2
[type] => select
[sort_order] => 0
)
)
)
In order to acces there are different methods E.g.: num_rows, row, rows
echo $query2->row['option_id'];
Will give the result as 2
According to the go documentation, Unix returns a local time.
Unix returns the local Time corresponding to the given Unix time
This means the output would depend on the machine your code runs on, which, most often is what you need, but sometimes, you may want to have the value in UTC.
To do so, I adapted the snippet to make it return a time in UTC:
i, err := strconv.ParseInt("1405544146", 10, 64)
if err != nil {
panic(err)
}
tm := time.Unix(i, 0)
fmt.Println(tm.UTC())
This prints on my machine (in CEST)

You can use git-copy to duplicate the repo with all histories.
git copy http://a.com/old.git http://a.com/new.git
If you are defining your function:
function test() {};
Then, this is equivalent to:
window.test = function() {} /* (in the browser) */
So spyOn(window, 'test')
should work.
If that is not, you should also be able to:
test = jasmine.createSpy();
If none of those are working, something else is going on with your setup.
I don't think your fakeElement
technique works because of what is going on behind the scenes. The original globalMethod still points to the same code. What spying does is proxy it, but only in the context of an object. If you can get your test code to call through the fakeElement it would work, but then you'd be able to give up global fns.
I had the same problem and I solved it this way:
If you know where libpython resides at, I supposed it would be /usr/local/lib/libpython2.7.so.1.0
in your case, you can just create a symbolic link to it:
sudo ln -s /usr/local/lib/libpython2.7.so.1.0 /usr/lib/libpython2.7.so.1.0
Then try running ldd
again and see if it worked.
You can do either:
$("h1").css("background-color", "yellow");
Or:
$("h1").css({backgroundColor: "yellow"});
select @currentTerm = CurrentTerm, @termID = TermID, @endDate = EndDate

['2010', '01', '31']
>>> year,month,date=a.split('-')
>>> year
'2010'
>>> month
'01'
>>> date
'31'
I experienced a similar problem and doing width:100%;
solved it for me. I came to this solution after trying an answer in this question and realizing that the very nature of an <iframe>
will make these javascript measurement tools inaccurate without using some complex function. Doing 100% is a simple way to take care of it in an iframe. I don't know about your issue since I'm not sure of what HTML elements you are manipulating.
Here is an up-to-date approach as of October 2020, with Android X. This comes from Android's documentation, "Enable multidex for apps with over 64K methods."
minSdk
>= 21You do not need to do anything. All of these devices use the Android RunTime (ART) VM, which supports multidex natively.
minSdk
< 21In your module-level build.gradle
, ensure that the following configurations are populated:
android {
defaultConfig {
multiDexEnabled true
}
}
dependencies {
implementation 'androidx.multidex:multidex:2.0.1'
}
You need to install explicit multidex support. The documentation includes three methods to do so, and you have to pick one.
For example, in your src/main/AndroidManifest.xml
, you can declare MultiDexApplication
as the application:name
:
<manifest package="com.your.package"
xmlns:android="http://schemas.android.com/apk/res/android">
<application android:name="androidx.multidex.MultiDexApplication" />
</manifest>
From JDK source code, I found below code
int oldCapacity = elementData.length;
int newCapacity = oldCapacity + (oldCapacity >> 1);
...or alternatively if you only want to show a portion of the time value use "Custom":
timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Custom;
timePicker.CustomFormat = "HH:mm"; // Only use hours and minutes
timePicker.ShowUpDown = true;
From digging into the iOS 8 docs that are available as of Sept 9th 3:30pm there is no mention of developer access to the NFC controller to perform any NFC operations; that includes reading tags, writing tags, pairing, payments, tag emulation... Given its an NXP controller the hardware has the capability to perform these features. They did mention a 3rd party app for the watch that allowed a hotel guest to open their room door with NFC. This is a classic use case for NFC and gives some indication that the NFC controller will be open to developers at some point. Remember, the watch is not supposed to be released until Q1 2015. So for now I'd say it's closed but will be open soon. Given the 'newness' of contactless payments for the general US consumer and the recent security breaches its not surprising Apple wants to keep this closed for a while.
Disclosure: Im the CEO of GoToTags, an NFC company with obvious vested interest in Apple opening up NFC to developers.
--- Correction & Update ---
The hotel app actually uses Bluetooth, not NFC. NFC is still often used for door unlocking, just not in this one example. NFC could be used if the watch has an open NFC controller.
I do know that Apple is aware of all of this and is discussing this with their top developers and stakeholders. There has already been massive negative push back on the lack of support for reading tags. As often the case in the past, I expect Apple to eventually open this up to developers for non-payment related functionality (reading tags, pairing). I do not think Apple will ever allow other wallets though. File sharing will likely be left to AirDrop as well.
--- Update on March 23rd 2016 ---
I am continually asked for updates about this topic, often with people referencing this post. With Apple releasing the iPhone SE, many are again asking why Apple has not supported tag reading yet. In summary Apple is more focused on Apple Pay succeeding than the other use cases for NFC for now. Apple could make a lot of money from Apple Pay, and has less to make from the other uses for NFC. Apple will likely open up NFC tag reading when they feel that consumer trust and security with NFC and Apple Pay is such that it wont put Apple Pay at risk. Further information here.
--- Update on May 24th 2017 ---
A developer in Greece has hacked the iPhone 6s to get it to read NFC tags via the NFC private frameworks; more info & video. While this isn't a long term solution, it provides some guidance on some outstanding question: Is there enough power in the iPhone's NFC controller to power an NFC tag? Looks like the answer is yes. From initial testing the range is a few cm, which isn't too bad. It might also be the power is tunable; this is being investigated at this time. The implications of this are significant. If the older model phones do have enough RF power for tag reading/writing, then when Apple does open up the SDK it means there will be 100Ms of iPhones that can read NFC tags, vs the case where only the new iPhones could.
List<Object> object = new List<Object>();
You cannot do this because List is an interface and you cannot create object of any interface or in other word you cannot instantiate any interface. Moreover, you can assign any object of class which implements List to its reference variable. For example you can do this:
list<Object> object = new ArrayList<Object>();
Here ArrayList is a class which implements List, you can use any class which implements List.
The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be nonnegative integer constants (except when using prepared statements).
With two arguments, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return. The offset of the initial row is 0 (not 1):
SELECT * FROM tbl LIMIT 5,10; # Retrieve rows 6-15
To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter. This statement retrieves all rows from the 96th row to the last:
SELECT * FROM tbl LIMIT 95,18446744073709551615;
With one argument, the value specifies the number of rows to return from the beginning of the result set:
SELECT * FROM tbl LIMIT 5; # Retrieve first 5 rows
In other words, LIMIT row_count is equivalent to LIMIT 0, row_count.

Thowable
catches really everything even ThreadDeath which gets thrown by default to stop a thread from the now deprecated Thread.stop()
method. So by catching Throwable
you can be sure that you'll never leave the try block without at least going through your catch block, but you should be prepared to also handle OutOfMemoryError
and InternalError
or StackOverflowError
.
Catching Throwable
is most useful for outer server loops that delegate all sorts of requests to outside code but may itself never terminate to keep the service alive.
Try the following
for ( const auto &p : table )
{
std::cout << p.first << '\t' << p.second << std::endl;
}
The same can be written using an ordinary for loop
for ( auto it = table.begin(); it != table.end(); ++it )
{
std::cout << it->first << '\t' << it->second << std::endl;
}
Take into account that value_type for std::map
is defined the following way
typedef pair<const Key, T> value_type
Thus in my example p is a const reference to the value_type where Key is std::string
and T is int
Also it would be better if the function would be declared as
void output( const map<string, int> &table );

I am taking Stephen Grider's React Native on Udemy and one of the students posted this in Lecture 50. Pasted verbatim in the command line (w/o '$' of course).
$ export "ANDROID_HOME=/usr/local/opt/android-sdk" >~/.bash_profile
none of the answers worked but this
\newcommand{\bcenter}{\begin{center}}
\newcommand{\ecenter}{\end{center}}
but then the following problem is that it works for only one figure and then will not for any other figures.
I just started learning R I knew it was going to be difficult but what's worst is that there is little to no info that I can refer to.
To summarize, JSX doesn't support comments, either html-like or js-like:
<div>
/* This will be rendered as text */
// as well as this
<!-- While this will cause compilation failure -->
</div>
and the only way to add comments "in" JSX is actually to escape into JS and comment in there:
<div>
{/* This won't be rendered */}
{// just be sure that your closing bracket is out of comment
}
</div>
if you don't want to make some nonsense like
<div style={{display:'none'}}>
actually, there are other stupid ways to add "comments"
but cluttering your DOM is not a good idea
</div>
Finally, if you do want to create a comment node via React, you have to go much fancier, check out this answer.
SQLAlchemy is very, very powerful. However it is not thread safe make sure you keep that in mind when working with cherrypy in thread-pool mode.
We actually override static methods (in delphi), it's a bit ugly, but it works just fine for our needs.
We use it so the classes can have a list of their available objects without the class instance, for example, we have a method that looks like this:
class function AvailableObjects: string; override;
begin
Result := 'Object1, Object2';
end;
It's ugly but necessary, this way we can instantiate just what is needed, instead of having all the classes instantianted just to search for the available objects.
This was a simple example, but the application itself is a client-server application which has all the classes available in just one server, and multiple different clients which might not need everything the server has and will never need an object instance.
So this is much easier to maintain than having one different server application for each client.
Hope the example was clear.
I tried replacing value
with Value
and it worked out. It has set the value
in input
tag now.
@Html.TextBoxFor(model => model.Destination, new { id = "txtPlace", Value= "3" })
The simplest thing you can do is cherry picking a range. It does the same as the rebase --onto
but is easier for the eyes :)
git cherry-pick quickfix1..quickfix2
The replace() method searches for a match between a substring (or regular expression) and a string, and replaces the matched substring with a new substring
Would be better to use a regex here then:
textTitle.replace(/ /g, '%20');
tail
does not blockAs always: For everything there is an answer which is short, easy to understand, easy to follow and completely wrong. Here tail -f /dev/null
falls into this category ;)
If you look at it with strace tail -f /dev/null
you will notice, that this solution is far from blocking! It's probably even worse than the sleep
solution in the question, as it uses (under Linux) precious resources like the inotify
system. Also other processes which write to /dev/null
make tail
loop. (On my Ubuntu64 16.10 this adds several 10 syscalls per second on an already busy system.)
Read: I do not know any way to archive this with the shell directly.
Everything (even sleep infinity
) can be interrupted by some signal. So if you want to be really sure it does not exceptionally return, it must run in a loop, like you already did for your sleep
. Please note, that (on Linux) /bin/sleep
apparently is capped at 24 days (have a look at strace sleep infinity
), hence the best you can do probably is:
while :; do sleep 2073600; done
(Note that I believe sleep
loops internally for higher values than 24 days, but this means: It is not blocking, it is very slowly looping. So why not move this loop to the outside?)
fifo
You can create something which really blocks as long as there are no signals send to the process. Following uses bash 4
, 2 PIDs and 1 fifo
:
bash -c 'coproc { exec >&-; read; }; eval exec "${COPROC[0]}<&-"; wait'
You can check that this really blocks with strace
if you like:
strace -ff bash -c '..see above..'
read
blocks if there is no input data (see some other answers). However, the tty
(aka. stdin
) usually is not a good source, as it is closed when the user logs out. Also it might steal some input from the tty
. Not nice.
To make read
block, we need to wait for something like a fifo
which will never return anything. In bash 4
there is a command which can exactly provide us with such a fifo
: coproc
. If we also wait the blocking read
(which is our coproc
), we are done. Sadly this needs to keep open two PIDs and a fifo
.
fifo
If you do not bother using a named fifo
, you can do this as follows:
mkfifo "$HOME/.pause.fifo" 2>/dev/null; read <"$HOME/.pause.fifo"
Not using a loop on the read is a bit sloppy, but you can reuse this fifo
as often as you like and make the read
s terminat using touch "$HOME/.pause.fifo"
(if there are more than a single read waiting, all are terminated at once).
pause()
syscallFor the infinite blocking there is a Linux kernel call, called pause()
, which does what we want: Wait forever (until a signal arrives). However there is no userspace program for this (yet).
Create such a program is easy. Here is a snippet to create a very small Linux program called pause
which pauses indefinitely (needs diet
, gcc
etc.):
printf '#include <unistd.h>\nint main(){for(;;)pause();}' > pause.c;
diet -Os cc pause.c -o pause;
strip -s pause;
ls -al pause
python
If you do not want to compile something yourself, but you have python
installed, you can use this under Linux:
python -c 'while 1: import ctypes; ctypes.CDLL(None).pause()'
(Note: Use exec python -c ...
to replace the current shell, this frees one PID. The solution can be improved with some IO redirection as well, freeing unused FDs. This is up to you.)
How this works (I think): ctypes.CDLL(None)
loads the standard C library and runs the pause()
function in it within some additional loop. Less efficient than the C version, but works.
Stay at the looping sleep. It's easy to understand, very portable, and blocks most of the time.
For those who are interested in using react hooks
, this might help you get started.
import React, { useState, useEffect, useRef } from 'react'
export default () => {
const [height, setHeight] = useState(0)
const ref = useRef(null)
useEffect(() => {
setHeight(ref.current.clientHeight)
})
return (
<div ref={ref}>
{height}
</div>
)
}
Here are two ways to pass value from Gradle to use in Java;
android {
buildTypes {
debug {
buildConfigField "int", "FOO", "42"
buildConfigField "String", "FOO_STRING", "\"foo\""
buildConfigField "boolean", "LOG", "true"
}
release {
buildConfigField "int", "FOO", "52"
buildConfigField "String", "FOO_STRING", "\"bar\""
buildConfigField "boolean", "LOG", "false"
}
}
}
You can access them with BuildConfig.FOO
android {
buildTypes {
debug{
resValue "string", "app_name", "My App Name Debug"
}
release {
resValue "string", "app_name", "My App Name"
}
}
}
You can access them in the usual way with @string/app_name
or R.string.app_name
If you would like to preserve the image as inline you can put vertical-align: top
or vertical-align: bottom
on it. By default it is aligned on the baseline hence the few pixels beneath it.
If you are using AFNetworking library to download image and that images are using in UITableview then You can use below code in cellForRowAtIndexPath
[self setImageWithURL:user.user_ProfilePicturePath toControl:cell.imgView];
-(void)setImageWithURL:(NSURL*)url toControl:(id)ctrl
{
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFImageRequestOperation *operation = [AFImageRequestOperation imageRequestOperationWithRequest:request imageProcessingBlock:nil success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
if (image) {
if([ctrl isKindOfClass:[UIButton class]])
{
UIButton btn =(UIButton)ctrl;
[btn setBackgroundImage:image forState:UIControlStateNormal];
}
else
{
UIImageView imgView = (UIImageView)ctrl;
imgView.image = image;
}
}
}
failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {
NSLog(@"No Image");
}];
[operation start];}
Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.
For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

Yes, you could make an indexer on your Record class that maps from the property name to the correct property. This would keep all the binding from property name to property in one place eg:
public class Record
{
public string ItemType { get; set; }
public string this[string propertyName]
{
set
{
switch (propertyName)
{
case "itemType":
ItemType = value;
break;
// etc
}
}
}
}
Alternatively, as others have mentioned, use reflection.
print((df.count(), len(df.columns)))
is easier for smaller datasets.
However if the dataset is huge, an alternative approach would be to use pandas and arrows to convert the dataframe to pandas df and call shape
spark.conf.set("spark.sql.execution.arrow.enabled", "true")
spark.conf.set("spark.sql.crossJoin.enabled", "true")
print(df.toPandas().shape)
You can try this:
d = pd.DataFrame(0, index=np.arange(len(data)), columns=feature_list)
Simple approach is close window on saveComand Implementation. Use below code to close window.
Application.Current.Windows[1].Close();
It will close the child window.

In Python3.6, the StringIO
and cStringIO
modules are gone, you should use io.StringIO
instead.So you should do this like the first answer:
import sys
from io import StringIO
old_stdout = sys.stdout
old_stderr = sys.stderr
my_stdout = sys.stdout = StringIO()
my_stderr = sys.stderr = StringIO()
# blah blah lots of code ...
sys.stdout = self.old_stdout
sys.stderr = self.old_stderr
// if you want to see the value of redirect output, be sure the std output is turn back
print(my_stdout.getvalue())
print(my_stderr.getvalue())
my_stdout.close()
my_stderr.close()

You can use two imbricated div. But you need a fixed width for your content, that's the only limitation.
<div style='float:right; width: 180px;'>
<div style='position: fixed'>

</div>
</div>
An alternative to System.Diagnostics.StackTrace
is to use System.Environment.StackTrace which returns a string-representation of the stacktrace.
Another useful option is to use the $CALLER
and $CALLSTACK
debugging variables in Visual Studio since this can be enabled run-time without rebuilding the application.

I start mysql from ./opt/lampp/xampp start
I do strace ./opt/lampp/sbin/mysqld
and see that my.cnf is there:
stat("/opt/lampp/etc/my.cnf", {st_mode=S_IFREG|0644, st_size=5050, ...}) = 0
openat(AT_FDCWD, "/opt/lampp/etc/my.cnf", O_RDONLY|O_CLOEXEC) = 3
hence, I add sql_mode config to /opt/lampp/etc/my.cnf
instead of /etc/mysql/my.cnf
This it not possible to use the CSS3 selector :first-of-type to select the first element with a given class name.
However, if the targeted element has a previous element sibling, you can combine the negation CSS pseudo-class and the adjacent sibling selectors to match an element that doesn't immediately have a previous element with the same class name :
:not(.myclass1) + .myclass1
Full working code example:
p:first-of-type {color:blue}_x000D_
p:not(.myclass1) + .myclass1 { color: red }_x000D_
p:not(.myclass2) + .myclass2 { color: green }
_x000D_
