This is gonna delete all the remote branches that are not present locally (in ruby):
bs = `git branch`.split; bs2 = `git branch -r | grep origin`.split.reject { |b| bs.include?(b.split('/')[1..-1].join('/')) }; bs2.each { |b| puts `git push origin --delete #{b.split('/')[1..-1].join('/')}` }
Explained:
# local branches
bs = `git branch`.split
# remote branches
bs2 = `git branch -r | grep origin`.split
# reject the branches that are present locally (removes origin/ in front)
bs2.reject! { |b| bs.include?(b.split('/')[1..-1].join('/')) }
# deletes the branches (removes origin/ in front)
bs2.each { |b| puts `git push origin --delete #{b.split('/')[1..-1].join('/')}` }
fairly simple if you use stored procedures:
call insert_user_and_profile('f00','http://www.f00.com');
full script:
drop table if exists users;
create table users
(
user_id int unsigned not null auto_increment primary key,
username varchar(32) unique not null
)
engine=innodb;
drop table if exists user_profile;
create table user_profile
(
profile_id int unsigned not null auto_increment primary key,
user_id int unsigned not null,
homepage varchar(255) not null,
key (user_id)
)
engine=innodb;
drop procedure if exists insert_user_and_profile;
delimiter #
create procedure insert_user_and_profile
(
in p_username varchar(32),
in p_homepage varchar(255)
)
begin
declare v_user_id int unsigned default 0;
insert into users (username) values (p_username);
set v_user_id = last_insert_id(); -- save the newly created user_id
insert into user_profile (user_id, homepage) values (v_user_id, p_homepage);
end#
delimiter ;
call insert_user_and_profile('f00','http://www.f00.com');
select * from users;
select * from user_profile;
This work for me..

You can use this module which is easy to use: https://github.com/halilb/react-native-textinput-effects
there should has a concurrent implemention of List interface supporting such operation.
try java.util.concurrent.CopyOnWriteArrayList.class
Something like this:
setUsers = function (data) {
for (k in data) {
user[k] = data[k];
}
}
I have found a very easy solution! If you have a form and you want to have a custom submit button you can use some code like this:
<button type="submit">
<img src="login.png" onmouseover="this.src='login2.png';" onmouseout="this.src='login.png';" />
</button>
Or just direct it to a link of a page.
However, if you can reliably test your code to confirm that calling Collect() won't have a negative impact then go ahead...
IMHO, this is similar to saying "If you can prove that your program will never have any bugs in the future, then go ahead..."
In all seriousness, forcing the GC is useful for debugging/testing purposes. If you feel like you need to do it at any other times, then either you are mistaken, or your program has been built wrong. Either way, the solution is not forcing the GC...
All the other solutions are creepy because they are from someone that arrogantly simply thinks that English is the only language in the world :)
All those solutions strip also diacritics like ç or à.
The perfect solution, as stated in PHP documentation, is simply:
$clear = strip_tags($des);
In addition to using an map-like object, there has been an actual Map
object for some time now, which is available in TypeScript when compiling to ES6, or when using a polyfill with the ES6 type-definitions:
let people = new Map<string, Person>();
It supports the same functionality as Object
, and more, with a slightly different syntax:
// Adding an item (a key-value pair):
people.set("John", { firstName: "John", lastName: "Doe" });
// Checking for the presence of a key:
people.has("John"); // true
// Retrieving a value by a key:
people.get("John").lastName; // "Doe"
// Deleting an item by a key:
people.delete("John");
This alone has several advantages over using a map-like object, such as:
Object
(no, Object
does not support numbers, it converts them to strings)--noImplicitAny
, as a Map
always has a key type and a value type, whereas an object might not have an index-signatureObject
Additionally, a Map
object provides a more powerful and elegant API for common tasks, most of which are not available through simple Object
s without hacking together helper functions (although some of these require a full ES6 iterator/iterable polyfill for ES5 targets or below):
// Iterate over Map entries:
people.forEach((person, key) => ...);
// Clear the Map:
people.clear();
// Get Map size:
people.size;
// Extract keys into array (in insertion order):
let keys = Array.from(people.keys());
// Extract values into array (in insertion order):
let values = Array.from(people.values());
%s will get all the values until it gets NULL i.e. '\0'.
char str1[] = "This is the end\0";
printf("%s",str1);
will give
This is the end
char str2[] = "this is\0 the end\0";
printf("%s",str2);
will give
this is
For repeating an action in the future, there is the built in setInterval
function that you can use instead of setTimeout
.
It has a similar signature, so the transition from one to another is simple:
setInterval(function() {
// do stuff
}, duration);
pthread_getthreadid_np
wasn't on my Mac os x. pthread_t
is an opaque type. Don't beat your head over it. Just assign it to void*
and call it good. If you need to printf
use %p

Use:
import tkinter as tk
if __name__ == '__main__':
root = tk.Tk()
root.title('Centered!')
w = 800
h = 650
ws = root.winfo_screenwidth()
hs = root.winfo_screenheight()
x = (ws/2) - (w/2)
y = (hs/2) - (h/2)
root.geometry('%dx%d+%d+%d' % (w, h, x, y))
root.mainloop()
And make sure your route in the list of routes:
./manage.py show_urls | grep path_or_name
Just try this, using underscore
var json1 = [{ value1: '1', value2: '2' },{ value1: '3', value2: '4' }];
var json2 = [{ value3: 'a', value4: 'b' },{ value3: 'c', value4: 'd' }];
var resultArray = [];
json1.forEach(function(obj, index){
resultArray.push(_.extend(obj, json2[index]));
});
console.log("Result Array", resultArray);
Result
Because fs.writefile
is a traditional asynchronous callback - you need to follow the promise spec and return a new promise wrapping it with a resolve and rejection handler like so:
return new Promise(function(resolve, reject) {
fs.writeFile("<filename.type>", data, '<file-encoding>', function(err) {
if (err) reject(err);
else resolve(data);
});
});
So in your code you would use it like so right after your call to .then()
:
.then(function(results) {
return new Promise(function(resolve, reject) {
fs.writeFile(ASIN + '.json', JSON.stringify(results), function(err) {
if (err) reject(err);
else resolve(data);
});
});
}).then(function(results) {
console.log("results here: " + results)
}).catch(function(err) {
console.log("error here: " + err);
});
In Swift 4 , just use this:
func buttonTapped(_ sender: UIButton) {
let buttonPostion = sender.convert(sender.bounds.origin, to: tableView)
if let indexPath = tableView.indexPathForRow(at: buttonPostion) {
let rowIndex = indexPath.row
}
}
I think this should work.

Use Hosts Commander. It's simple and powerful. Translated description (from russian) here.
hosts add another.dev 192.168.1.1 # Remote host
hosts add test.local # 127.0.0.1 used by default
hosts set myhost.dev # new comment
hosts rem *.local
hosts enable local*
hosts disable localhost
...and many others...
Usage:
hosts - run hosts command interpreter
hosts <command> <params> - execute hosts command
Commands:
add <host> <aliases> <addr> # <comment> - add new host
set <host|mask> <addr> # <comment> - set ip and comment for host
rem <host|mask> - remove host
on <host|mask> - enable host
off <host|mask> - disable host
view [all] <mask> - display enabled and visible, or all hosts
hide <host|mask> - hide host from 'hosts view'
show <host|mask> - show host in 'hosts view'
print - display raw hosts file
format - format host rows
clean - format and remove all comments
rollback - rollback last operation
backup - backup hosts file
restore - restore hosts file from backup
recreate - empty hosts file
open - open hosts file in notepad
In controller:
function innerItem($scope, $element){
var jQueryInnerItem = $($element);
}
You can build your class files within the VS Command prompt (so that all required environment variables are loaded), not the default Windows command window.
To know more about command line building with csc.exe (the compiler), see this article.

The problem with maintenance info sections
is that command tries to extract information from the section header of the binary. It does not work if the binary is tripped (e.g by sstrip
) or it gives wrong information when the loader may change the memory permission after loading (e.g. the case of RELRO
).
I had to benchmark the different ways. I shall comment on my findings but, in short, the fastest way is to use a plain old BufferedInputStream over a FileInputStream. If many files must be read then three threads will reduce the total execution time to roughly half, but adding more threads will progressively degrade performance until making it take three times longer to complete with twenty threads than with just one thread.
The assumption is that you must read a file and do something meaningful with its contents. In the examples here is reading lines from a log and count the ones which contain values that exceed a certain threshold. So I am assuming that the one-liner Java 8 Files.lines(Paths.get("/path/to/file.txt")).map(line -> line.split(";"))
is not an option.
I tested on Java 1.8, Windows 7 and both SSD and HDD drives.
I wrote six different implementations:
rawParse: Use BufferedInputStream over a FileInputStream and then cut lines reading byte by byte. This outperformed any other single-thread approach, but it may be very inconvenient for non-ASCII files.
lineReaderParse: Use a BufferedReader over a FileReader, read line by line, split lines by calling String.split(). This is approximatedly 20% slower that rawParse.
lineReaderParseParallel: This is the same as lineReaderParse, but it uses several threads. This is the fastest option overall in all cases.
nioFilesParse: Use java.nio.files.Files.lines()
nioAsyncParse: Use an AsynchronousFileChannel with a completion handler and a thread pool.
nioMemoryMappedParse: Use a memory-mapped file. This is really a bad idea yielding execution times at least three times longer than any other implementation.
These are the average times for reading 204 files of 4 MB each on an quad-core i7 and SSD drive. The files are generated on the fly to avoid disk caching.
rawParse 11.10 sec
lineReaderParse 13.86 sec
lineReaderParseParallel 6.00 sec
nioFilesParse 13.52 sec
nioAsyncParse 16.06 sec
nioMemoryMappedParse 37.68 sec
I found a difference smaller than I expected between running on an SSD or an HDD drive being the SSD approximately 15% faster. This may be because the files are generated on an unfragmented HDD and they are read sequentially, therefore the spinning drive can perform nearly as an SSD.
I was surprised by the low performance of the nioAsyncParse implementation. Either I have implemented something in the wrong way or the multi-thread implementation using NIO and a completion handler performs the same (or even worse) than a single-thread implementation with the java.io API. Moreover the asynchronous parse with a CompletionHandler is much longer in lines of code and tricky to implement correctly than a straight implementation on old streams.
Now the six implementations followed by a class containing them all plus a parametrizable main() method that allows to play with the number of files, file size and concurrency degree. Note that the size of the files varies plus minus 20%. This is to avoid any effect due to all the files being of exactly the same size.

Java says that the default length of a JAVA array at the time of initialization will be 10.
private static final int DEFAULT_CAPACITY = 10;

What even is ‘children’?
The React docs say that you can use
props.children
on components that represent ‘generic boxes’ and that don’t know their children ahead of time. For me, that didn’t really clear things up. I’m sure for some, that definition makes perfect sense but it didn’t for me.My simple explanation of what
this.props.children
does is that it is used to display whatever you include between the opening and closing tags when invoking a component.A simple example:
Here’s an example of a stateless function that is used to create a component. Again, since this is a function, there is no
this
keyword so just useprops.children
const Picture = (props) => {
return (
<div>
<img src={props.src}/>
{props.children}
</div>
)
}
This component contains an
<img>
that is receiving someprops
and then it is displaying{props.children}
.Whenever this component is invoked
{props.children}
will also be displayed and this is just a reference to what is between the opening and closing tags of the component.
//App.js
render () {
return (
<div className='container'>
<Picture key={picture.id} src={picture.src}>
//what is placed here is passed as props.children
</Picture>
</div>
)
}
Instead of invoking the component with a self-closing tag
<Picture />
if you invoke it will full opening and closing tags<Picture> </Picture>
you can then place more code between it.This de-couples the
<Picture>
component from its content and makes it more reusable.
Reference: A quick intro to React’s props.children
This is what i do and it works everythere :)
.container {
background: url(${myImage})
background-attachment: fixed;
background-size: cover;
transform: scale(1.1, 1.1);

The documentation for the Python 3 CSV module provides this example:
with open('example.csv', newline='') as csvfile:
dialect = csv.Sniffer().sniff(csvfile.read(1024))
csvfile.seek(0)
reader = csv.reader(csvfile, dialect)
# ... process CSV file contents here ...
The Sniffer
will try to auto-detect many things about the CSV file. You need to explicitly call its has_header()
method to determine whether the file has a header line. If it does, then skip the first row when iterating the CSV rows. You can do it like this:
if sniffer.has_header():
for header_row in reader:
break
for data_row in reader:
# do something with the row

The -Wl,xxx
option for gcc passes a comma-separated list of tokens as a space-separated list of arguments to the linker. So
gcc -Wl,aaa,bbb,ccc
eventually becomes a linker call
ld aaa bbb ccc
In your case, you want to say "ld -rpath .
", so you pass this to gcc as -Wl,-rpath,.
Alternatively, you can specify repeat instances of -Wl
:
gcc -Wl,aaa -Wl,bbb -Wl,ccc
Note that there is no comma between aaa
and the second -Wl
.
Or, in your case, -Wl,-rpath -Wl,.
.
You can pipe grep
result to head
in conjunction with stdbuf.
Note, that in order to ensure stopping after Nth match, you need to using stdbuf
to make sure grep
don't buffer its output:
stdbuf -oL grep -rl 'pattern' * | head -n1
stdbuf -oL grep -o -a -m 1 -h -r "Pulsanti Operietur" /path/to/dir | head -n1
stdbuf -oL grep -nH -m 1 -R "django.conf.urls.defaults" * | head -n1
As soon as head
consumes 1 line, it terminated and grep
will receive SIGPIPE
because it still output something to pipe while head
was gone.
This assumed that no file names contain newline.
Then you'd want to do this instead:
print str(int(1.0/3.0*100))+'%'
The .0
denotes them as floats and int()
rounds them to integers afterwards again.
I (and the rest of our team in my company) prefer to raise exceptions instead of returning error codes. Error codes have to be checked everywhere, passed around, and tend to make the code unreadable when the amount of code becomes bigger.
The error class would then define the message.
PS: and actually also care for internationalization !
PPS: you could also redefine the raise-method and add logging, filtering etc. if required (at leastin environments, where the Exception classes and friends are extendable/changeable)
Here is how to do this on Windows without third-party tools:
Import certificate to the certificate store. In Windows Explorer select "Install Certificate" in context menu. Follow the wizard and accept default options "Local User" and "Automatically".
Find your certificate in certificate store. On Windows 10 run the "Manage User Certificates" MMC. On Windows 2013 the MMC is called "Certificates". On Windows 10 by default your certificate should be under "Personal"->"Certificates" node.
Export Certificate. In context menu select "Export..." menu:
Select "Yes, export the private key":
You will see that .PFX option is enabled in this case:
Specify password for private key.
if you are calling from static
method, use :
TestGameTable.class.getClassLoader().getResource("dice.jpg");
The suggested answer by Loïc MICHEL blindly writes a new value to the TrustedHosts entry.
I believe, a better way would be to first query TrustedHosts.
As Jeffery Hicks posted in 2010, first query the TrustedHosts entry:
PS C:\> $current=(get-item WSMan:\localhost\Client\TrustedHosts).value
PS C:\> $current+=",testdsk23,alpha123"
PS C:\> set-item WSMan:\localhost\Client\TrustedHosts –value $current

You can use
function roundToTwo(num) {
return +(Math.round(num + "e+2") + "e-2");
}
I found this over on MDN. Their way avoids the problem with 1.005 that was mentioned.
roundToTwo(1.005)
1.01
roundToTwo(10)

roundToTwo(1.7777777)

Neither hacking PYTHONPATH
nor sys.path
is a good idea due to the before mentioned reasons. And for linking the current project into the site-packages folder there is actually a better way than python setup.py develop
, as explained here:
pip install --editable path/to/project
If you don't already have a setup.py in your project's root folder, this one is good enough to start with:
from setuptools import setup
setup('project')
Here is my platform specific code(unix)
public static List<File> findFiles(String dir, String... names)

List<File> result = new LinkedList<File>();
if (names.length > 1)
{
List<String> newNames = new LinkedList<String>(Arrays.asList(names));
String first = newNames.remove(0);
command.add("-name");
command.add(first);
for (String newName : newNames)
{
command.add("-or");
command.add("-name");
command.add(newName);
}
}
else if (names.length > 0)
{
command.add("-name");
command.add(names[0]);

while ((line = br.readLine()) != null)
{

Worth mentioning Java 8 approach, using BiConsumer
and lambda functions:
BiConsumer<TypeKey, TypeValue> consumer = (o1, o2) ->
System.out.println(o1 + ", " + o2);
example.forEach(consumer);
Assuming that you've overridden toString
method of the two types if needed.
You can use prop() for this, as Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop()
method provides a way to explicitly retrieve property values, while .attr()
retrieves attributes.
var prop=false;
if(value == 1) {
prop=true;
}
$('#checkbox').prop('checked',prop);
or simply,
$('#checkbox').prop('checked',(value == 1));

$(document).ready(function() {_x000D_

Splits an array in multiple arrays with a fixed maximum size.
public static <T extends Object> List<T[]> splitArray(T[] array, int max){
int x = array.length / max;
int r = (array.length % max); // remainder
int lower = 0;
int upper = 0;
List<T[]> list = new ArrayList<T[]>();
int i=0;
for(i=0; i<x; i++){
upper += max;
list.add(Arrays.copyOfRange(array, lower, upper));
lower = upper;
}
if(r > 0){
list.add(Arrays.copyOfRange(array, lower, (lower + r)));
}
return list;
}
Example - an Array of 11 shall be splitted into multiple Arrays not exceeding a size of 5:
// create and populate an array
Integer[] arr = new Integer[11];
for(int i=0; i<arr.length; i++){
arr[i] = i;
}
// split into pieces with a max. size of 5
List<Integer[]> list = ArrayUtil.splitArray(arr, 5);
// check
for(int i=0; i<list.size(); i++){
System.out.println("Array " + i);
for(int j=0; j<list.get(i).length; j++){
System.out.println(" " + list.get(i)[j]);
}
}
Output:
Array 0

Have created a simple dictionary in JS here:
function JSdict() {
this.Keys = [];
this.Values = [];
}
// Check if dictionary extensions aren't implemented yet.
// Returns value of a key
if (!JSdict.prototype.getVal) {
JSdict.prototype.getVal = function (key) {
if (key == null) {
return "Key cannot be null";
}
for (var i = 0; i < this.Keys.length; i++) {
if (this.Keys[i] == key) {
return this.Values[i];
}
}
return "Key not found!";
}
}
// Check if dictionary extensions aren't implemented yet.
// Updates value of a key
if (!JSdict.prototype.update) {
JSdict.prototype.update = function (key, val) {
if (key == null || val == null) {
return "Key or Value cannot be null";
}
// Verify dict integrity before each operation
if (keysLength != valsLength) {
return "Dictionary inconsistent. Keys length don't match values!";
}
var keysLength = this.Keys.length;
var valsLength = this.Values.length;
var flag = false;
for (var i = 0; i < keysLength; i++) {
if (this.Keys[i] == key) {
this.Values[i] = val;
flag = true;
break;
}
}
if (!flag) {
return "Key does not exist";
}
}
}
// Check if dictionary extensions aren't implemented yet.
// Adds a unique key value pair
if (!JSdict.prototype.add) {
JSdict.prototype.add = function (key, val) {
// Allow only strings or numbers as keys
if (typeof (key) == "number" || typeof (key) == "string") {
if (key == null || val == null) {
return "Key or Value cannot be null";
}
if (keysLength != valsLength) {
return "Dictionary inconsistent. Keys length don't match values!";
}

}
}
this.Keys.push(key);
this.Values.push(val);
}
else {
return "Only number or string can be key!";
}
}
}
// Check if dictionary extensions aren't implemented yet.
// Removes a key value pair
if (!JSdict.prototype.remove) {

break;
}
}
if (!flag) {
return "Key does not exist";
}
}
}
var dict = new JSdict();
dict.add(1, "one")
dict.add(1, "one more")
"Duplicate keys not allowed!"
dict.getVal(1)
"one"
dict.update(1, "onne")
dict.getVal(1)
"onne"
dict.remove(1)
dict.getVal(1)
"Key not found!"
This is just a basic simulation. It can be further optimized by implementing a better running time algorithm to work in atleast O(nlogn) time complexity or even less. Like merge/quick sort on arrays and then some B-search for lookups. I Didn't give a try or searched about mapping a hash function in JS.
Also, Key and Value for the JSdict obj can be turned into private variables to be sneaky.
Hope this helps!
EDIT >> After implementing the above, I personally used the JS objects as associative arrays that are available out-of-the-box.
However, I would like to make a special mention about two methods that actually proved helpful to make it a convenient hashtable experience.
Viz: dict.hasOwnProperty(key) and delete dict[key]
Read this post as a good resource on this implementation/usage. Dynamically creating keys in JavaScript associative array
THanks!
Did you sort this? I just found this code here:
I think I'll need to do a bit of tweaking, but essentially this has sorted it for me!
I hope it does for you too!

Came across the same problem. Fixed it by adding to my controller:
skip_before_filter :verify_authenticity_token, if: :json_request?
I know it's a bit late, but I've tried everything above and nothing worked. The real problem was that I'm using hibernate, so it was trying to connect to mysql but was not able, thats why it showed time out.
Just to let u guys know, I'm using RDS(Amazon), so just to make a test I changed to my local mysql and it worked perfectly.
Hope that this answer helps somebody.
Thanks.
There's something wrong. You have written:
string source_dir = @"E:\\Debug\\VipBat\\{0}";
and the error was
Could not find a part of the path E\Debug\VCCSBat
This is not the same directory.
In your code there's a problem, you have to use:
string source_dir = @"E:\Debug\VipBat"; // remove {0} and the \\ if using @
or
string source_dir = "E:\\Debug\\VipBat"; // remove {0} and the @ if using \\
Try this on Windows:

Here is the reason. Starting from Jersey 2.26, Jersey removed HK2 as a hard dependency. It created an SPI as a facade for the dependency injection provider, in the form of the InjectionManager
and InjectionManagerFactory
. So for Jersey to run, we need to have an implementation of the InjectionManagerFactory
. There are two implementations of this, which are for HK2 and CDI. The HK2 dependency is the jersey-hk2
others are talking about.
<dependency>
<groupId>org.glassfish.jersey.inject</groupId>
<artifactId>jersey-hk2</artifactId>
<version>2.26</version>
</dependency>
The CDI dependency is
<dependency>
<groupId>org.glassfish.jersey.inject</groupId>
<artifactId>jersey-cdi2-se</artifactId>
<version>2.26</version>
</dependency>
This (jersey-cdi2-se) should only be used for SE environments and not EE environments.
Jersey made this change to allow others to provide their own dependency injection framework. They don't have any plans to implement any other InjectionManager
s, though others have made attempts at implementing one for Guice.
The direct cast var ListOfY = (List<Y>)ListOfX
is not possible because it would require co/contravariance of the List<T>
type, and that just can't be guaranteed in every case. Please read on to see the solutions to this casting problem.
While it seems normal to be able to write code like this:
List<Animal> animals = (List<Animal>) mammalList;
because we can guarantee that every mammal will be an animal, this is obviously a mistake:
List<Mammal> mammals = (List<Mammal>) animalList;
since not every animal is a mammal.
However, using C# 3 and above, you can use
IEnumerable<Animal> animals = mammalList.Cast<Animal>();
that eases the casting a little. This is syntactically equivalent to your one-by-one adding code, as it uses an explicit cast to cast each Mammal
in the list to an Animal
, and will fail if the cast is not successfull.
If you like more control over the casting / conversion process, you could use the ConvertAll
method of the List<T>
class, which can use a supplied expression to convert the items. It has the added benifit that it returns a List
, instead of IEnumerable
, so no .ToList()
is necessary.
List<object> o = new List<object>();
o.Add("one");
o.Add("two");
o.Add(3);
IEnumerable<string> s1 = o.Cast<string>(); //fails on the 3rd item
List<string> s2 = o.ConvertAll(x => x.ToString()); //succeeds
Try setting a custom CultureInfo for CurrentCulture and CurrentUICulture.
Globalization.CultureInfo customCulture = new Globalization.CultureInfo("en-US", true);
customCulture.DateTimeFormat.ShortDatePattern = "yyyy-MM-dd h:mm tt";
System.Threading.Thread.CurrentThread.CurrentCulture = customCulture;
System.Threading.Thread.CurrentThread.CurrentUICulture = customCulture;
DateTime newDate = System.Convert.ToDateTime(DateTime.Now.ToString("yyyy-MM-dd h:mm tt"));
Why not just put an executable somewhere in my $PATH
~/.local/bin directory
is theoretically expected to be in your $PATH
.
According to these people it's a bug not adding it in the $PATH
when using systemd
.
This answer explains it more extensively.
But even if your distro includes the ~/.local/bin
directory to the $PATH
, it might be in the following form (inside ~/.profile
):
if [ -d "$HOME/.local/bin" ] ; then
PATH="$HOME/.local/bin:$PATH"
fi
which would require you to logout and login again, if the directory was not there before.
You need to wrap your input with component, and add containerElement property with value 'label' ...
<RaisedButton
containerElement='label' // <-- Just add me!
label='My Label'>
<input type="file" />
</RaisedButton>
You can read more about it in this GitHub issue.
EDIT: Update 2019.
Check at the bottom answer from @galki
TLDR;
<input
accept="image/*"
className={classes.input}
style={{ display: 'none' }}

<label htmlFor="raised-button-file">
<Button variant="raised" component="span" className={classes.button}>

I was looking for a long time an answer that solve the problem and this is the way I did it
I take the file with expo-document-picker
const pickDocument = async (tDocument) => {
let result = await DocumentPicker.getDocumentAsync();
result.type = mimetype(result.name);
if (result.type === undefined){
alert("not allowed extention");
return null;
}
let formDat = new FormData();
formDat.append("file", result);
uploadDoc(formDat);
};
const mimetype = (name) => {
let allow = {"png":"image/png","pdf":"application/json","jpeg":"image/jpeg", "jpg":"image/jpg"};
let extention = name.split(".")[1];
if (allow[extention] !== undefined){
return allow[extention]
}
else {
return undefined
}
}
const uploadDoc = (data) => {
fetch("MyApi", {
method: "POST",
body: data
}).then(res => res.json())
.then(response =>{
if (response.result === 1) {
//somecode
} else {
//somecode
}
});
}
this is because android doesn't manage the mime-type of your file so if you put away the header "Content-type" and instead you put the mime-type on the file it gonna send the correct header
works on IOS an Android
I would like to correct the @Neal answer which was pretty good for integers, but the number 1 would return a length of 0 in the previous case.
function Longueur(numberlen)
{
var length = 0, i; //define `i` with `var` as not to clutter the global scope
numberlen = parseInt(numberlen);
for(i = numberlen; i >= 1; i)
{
++length;
i = Math.floor(i/10);
}
return length;
}
Sometimes it's knowing what to ask. I didn't know as I am a developer who has taken on some DevOps work.
Apparently 'passwordless' or NOPASSWD login is a thing which you need to put in the /etc/sudoers file.
The answer to my question is at Ansible: best practice for maintaining list of sudoers.
The Ansible playbook code fragment looks like this from my problem:
- name: Make sure we have a 'wheel' group
group:
name: wheel
state: present
- name: Allow 'wheel' group to have passwordless sudo
lineinfile:
dest: /etc/sudoers
state: present
regexp: '^%wheel'
line: '%wheel ALL=(ALL) NOPASSWD: ALL'
validate: 'visudo -cf %s'
- name: Add sudoers users to wheel group
user:
name=deployer
groups=wheel
append=yes
state=present
createhome=yes
- name: Set up authorized keys for the deployer user
authorized_key: user=deployer key="{{item}}"
with_file:
- /home/railsdev/.ssh/id_rsa.pub
And the best part is that the solution is idempotent. It doesn't add the line
%wheel ALL=(ALL) NOPASSWD: ALL
to /etc/sudoers when the playbook is run a subsequent time. And yes...I was able to ssh into the server as "deployer" and run sudo commands without having to give a password.
It is only required if you aren't using the default values for version
and encoding
(which you are in that example).
The only thing working for me is using the password android
. Why is that not mentioned in any guides out there?
set up a new postgresql server and replace its data folder with the files from your external disk.
You will then be able to start that postgresql server up and retrieve the data using pg_dump (pg_dump -s for the schema-only as mentioned)

A very un-restrictive MIT Licensed C# / .NET library can be found at,
https://www.codeproject.com/articles/1107480/dsplib-fft-dft-fourier-transform-library-for-net
This library is fast as it parallel threads on multiple cores and is very complete and ready to use.
Below is a fully functional example of what I believe you're trying to do (with a functional snippet).
Based on your question, you seem to be modifying 1 property in state
for all of your elements. That's why when you click on one, all of them are being changed.
In particular, notice that the state tracks an index of which element is active. When MyClickable
is clicked, it tells the Container
its index, Container
updates the state
, and subsequently the isActive
property of the appropriate MyClickable
s.

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable
elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.
// New render method for `Container`
render() {
const clickables = [
{ name: "a" },
{ name: "b" },
{ name: "c" },
]
return <div>
{ clickables.map(function(clickable, i) {
return <MyClickable key={ clickable.name }
name={ clickable.name }
index={ i }
isActive={ this.state.activeIndex === i }
onClick={ this.handleClick }
/>
} )
}
</div>
}
Raymond's answer is great for python2 (though, you don't need the abs() nor the parens around 10 ** 8). However, for python3, there are important caveats. First, you'll need to make sure you are passing an encoded string. These days, in most circumstances, it's probably also better to shy away from sha-1 and use something like sha-256, instead. So, the hashlib approach would be:
>>> import hashlib
>>> s = 'your string'
>>> int(hashlib.sha256(s.encode('utf-8')).hexdigest(), 16) % 10**8
80262417
If you want to use the hash() function instead, the important caveat is that, unlike in Python 2.x, in Python 3.x, the result of hash() will only be consistent within a process, not across python invocations. See here:
$ python -V
Python 2.7.5
$ python -c 'print(hash("foo"))'
-4177197833195190597
$ python -c 'print(hash("foo"))'
-4177197833195190597
$ python3 -V
Python 3.4.2
$ python3 -c 'print(hash("foo"))'
5790391865899772265
$ python3 -c 'print(hash("foo"))'
-8152690834165248934
This means the hash()-based solution suggested, which can be shortened to just:
hash(s) % 10**8
will only return the same value within a given script run:
#Python 2:
$ python2 -c 's="your string"; print(hash(s) % 10**8)'
52304543
$ python2 -c 's="your string"; print(hash(s) % 10**8)'
52304543
#Python 3:
$ python3 -c 's="your string"; print(hash(s) % 10**8)'
12954124
$ python3 -c 's="your string"; print(hash(s) % 10**8)'
32065451
So, depending on if this matters in your application (it did in mine), you'll probably want to stick to the hashlib-based approach.

Don't use GitHub as a Maven Repository.
Edit: This option gets a lot of down votes, but no comments as to why. This is the correct option regardless of the technical capabilities to actually host on GitHub. Hosting on GitHub is wrong for all the reasons outlined below and without comments I can't improve the answer to clarify your issues.
Best Option - Collaborate with the Original Project
The best option is to convince the original project to include your changes and stick with the original.
Alternative - Maintain your own Fork
Since you have forked an open source library, and your fork is also open source, you can upload your fork to Maven Central (read Guide to uploading artifacts to the Central Repository) by giving it a new groupId
and maybe a new artifactId
.
Only consider this option if you are willing to maintain this fork until the changes are incorporated into the original project and then you should abandon this one.
Really consider hard whether a fork is the right option. Read the myriad Google results for 'why not to fork'
Reasoning
Bloating your repository with jars increases download size for no benefit
A jar is an output
of your project, it can be regenerated at any time from its inputs
, and your GitHub repo should contain only inputs
.
Don't believe me? Then check Google results for 'dont store binaries in git'.
GitHub's help Working with large files will tell you the same thing. Admittedly jar's aren't large but they are larger than the source code and once a jar has been created by a release they have no reason to be versioned - that is what a new release is for.
Defining multiple repos in your pom.xml slows your build down by Number of Repositories times Number of Artifacts
Stephen Connolly says:
If anyone adds your repo they impact their build performance as they now have another repo to check artifacts against... It's not a big problem if you only have to add one repo... But the problem grows and the next thing you know your maven build is checking 50 repos for every artifact and build time is a dog.
That's right! Maven needs to check every artifact (and its dependencies) defined in your pom.xml against every Repository you have defined, as a newer version might be available in any of those repositories.
Try it out for yourself and you will feel the pain of a slow build.
The best place for artifacts is in Maven Central, as its the central place for jars, and this means your build will only ever check one place.
You can read some more about repositories at Maven's documentation on Introduction to Repositories

To properly escape spaces as well as the rest of the special characters, use System.Uri.EscapeDataString(string stringToEscape)
.
Read carefully about the reason.
"Failed to resolve version for org.apache.maven.archetypes:maven-archetype- webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype- webapp/maven-metadata.xml in local"
So all you need to do is download the maven-metadata.xml to your {HOME}.m2\repository
That's it.
UPDATE
Back in my naïve days, I suggested doing this manually (it was a simple solution to a simple question), however due to this becoming more and more popular, I'd recommend using the library CsvHelper that does all the safety checks, etc.
CSV is way more complicated than what the question/answer suggests.
Original Answer
As you already have a loop, consider doing it like this:
//before your loop
var csv = new StringBuilder();
//in your loop
var first = reader[0].ToString();
var second = image.ToString();
//Suggestion made by KyleMit
var newLine = string.Format("{0},{1}", first, second);
csv.AppendLine(newLine);
//after your loop
File.WriteAllText(filePath, csv.ToString());
Or something to this effect. My reasoning is: you won't be need to write to the file for every item, you will only be opening the stream once and then writing to it.
You can replace
File.WriteAllText(filePath, csv.ToString());
with
File.AppendAllText(filePath, csv.ToString());
if you want to keep previous versions of csv in the same file
C# 6
If you are using c# 6.0 then you can do the following
var newLine = $"{first},{second}"
EDIT
Here is a link to a question that explains what Environment.NewLine
does.
Use this one:
Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")
Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")
With rng.Validation
.Delete 'delete previous validation
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
Formula1:="='" & ws.Name & "'!" & range1.Address
End With
Note that when you're using Dim range1, rng As range
, only rng
has type of Range
, but range1
is Variant
. That's why I'm using Dim range1 As Range, rng As Range
.
About meaning of parameters you can read is MSDN, but in short:
Type:=xlValidateList
means validation type, in that case you should select value from listAlertStyle:=xlValidAlertStop
specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.Operator:= xlBetween
is odd. It can be used only if two formulas are provided for validation.Formula1:="='" & ws.Name & "'!" & range1.Address
for list data validation provides address of list with values (in format =Sheet!A1:A5
)You can call the method getBoundingClientRect()
on a reference to the element. Then you can examine the top
, left
, right
and/or bottom
properties...
var offsets = document.getElementById('11a').getBoundingClientRect();
var top = offsets.top;
var left = offsets.left;
If using jQuery, you can use the more succinct code...
var offsets = $('#11a').offset();
var top = offsets.top;
var left = offsets.left;

To read you should create an instance of ifsteam and not ofstream.
ifstream iusrfile;
You should open the file in read mode.
iusrfile.open("usrfile.txt", ifstream::in);
Also this statement is not correct.
cout<<iusrfile;
If you are trying to print the data you read from the file you should do:
cout<<usr;
You can read more about ifstream and its API here
To get it to work with FullScreen:
Use the ionic keyboard plugin. This allows you to listen for when the keyboard appears and disappears.
OnDeviceReady add these event listeners:
// Allow Screen to Move Up when Keyboard is Present
window.addEventListener('native.keyboardshow', onKeyboardShow);
// Reset Screen after Keyboard hides
window.addEventListener('native.keyboardhide', onKeyboardHide);
The Logic:
function onKeyboardShow(e) {
// Get Focused Element
var thisElement = $(':focus');
// Get input size
var i = thisElement.height();
// Get Window Height
var h = $(window).height()
// Get Keyboard Height
var kH = e.keyboardHeight
// Get Focused Element Top Offset
var eH = thisElement.offset().top;
// Top of Input should still be visible (30 = Fixed Header)
var vS = h - kH;
i = i > vS ? (vS - 30) : i;
// Get Difference
var diff = (vS - eH - i);
if (diff < 0) {
var parent = $('.myOuter-xs.myOuter-md');
// Add Padding
var marginTop = parseInt(parent.css('marginTop')) + diff - 25;
parent.css('marginTop', marginTop + 'px');
}
}
function onKeyboardHide(e) {
// Remove All Style Attributes from Parent Div
$('.myOuter-xs.myOuter-md').removeAttr('style');
}
Basically if they difference is minus then that is the amount of pixels that the keyboard is covering of your input. So if you adjust your parent div by this that should counteract it.
Adding timeouts to the logic say 300ms should also optimise performance (as this will allow keyboard time to appear.
Just include #xxx
in your commit message to reference an issue without closing it.
With new GitHub issues 2.0 you can use these synonyms to reference an issue and close it (in your commit message):
fix #xxx
fixes #xxx
fixed #xxx
close #xxx
closes #xxx
closed #xxx
resolve #xxx
resolves #xxx
resolved #xxx
You can also substitute #xxx
with gh-xxx
.
Referencing and closing issues across repos also works:

Basically reload as in allyourcode's asnwer. But it won't change underlying the code of already instantiated object or referenced functions. Extending from his answer:
#Make a simple function that prints "version 1"

# Run the module
shell2$ python

True
# Change mymodule to print "version 2" (without exiting the python REPL)
shell2$ echo 'def x(): print "version 2"' > mymodule.py

In my case this error appeared when I asigned to both dynamic created controls (combobox), same created control from other class.
//dynamic created controls
ComboBox combobox1 = ManagerControls.myCombobox1;
...some events
ComboBox combobox2 = ManagerControl.myComboBox2;
...some events
.
//method in constructor
public static void InitializeDynamicControls()
{
ComboBox cb = new ComboBox();
cb.Background = new SolidColorBrush(Colors.Blue);
...
cb.Width = 100;
cb.Text = "Select window";
ManagerControls.myCombobox1 = cb;
ManagerControls.myComboBox2 = cb; // <-- error here
}
Solution: create another ComboBox cb2
and assign it to ManagerControls.myComboBox2
.

This might help someone:
I am installing the latest Java on my system for development, and currently it's Java SE 7. Now, let's dive into this "madness", as you put it...
All of these are the same (when developers are talking about Java for development):
Starting with Java v1.5:
And we can assume this will remain for future versions.
Next, for developers, download JDK, not JRE.
JDK will contain JRE. If you need JDK and JRE, get JDK. Both will be installed from the single JDK install, as you will see below.
As someone above mentioned:
Here's the step by step links I followed (one step leads to the next, this is all for a single download) to download Java for development (JDK):
Keep in mind the above links are for reference purposes only, to show you the step by step method of what it takes to download the JDK.
And install with default settings to:
Remember from above that JDK contains JRE, which makes sense if you know what they both are. Again, see above.
After your install, double check “C:\Program Files\Java” to see both these folders. Now you know what they are and why they are there.
I know I wrote this for newbies, but I enjoy knowing things in full detail, so I hope this helps.
The error:
'int' object has no attribute '__getitem__'
means that you're attempting to apply the index operator []
on an int, not a list. So is col
not a list, even when it should be? Let's start from that.
Look here:
col = [[0 for col in range(5)] for row in range(6)]
Use a different variable name inside, looks like the list comprehension overwrites the col
variable during iteration. (Not during the iteration when you set col
, but during the following ones.)
Do everything suggested by ziesemer.
You may also want to :
ArrayList<String> list = new ArrayList<String>();
list.add("blah");
list.add("bleh");
JSONArray jsArray = new JSONArray(list);
This is only an example using a string arraylist
If you're using Swift 2, now you can only use print() to write something to the output.
Apple has combined both println() and print() functions into one.
Updated to iOS 9
By default, the function terminates the line it prints by adding a line break.
print("Hello Swift")
Terminator
To print a value without a line break after it, pass an empty string as the terminator
print("Hello Swift", terminator: "")
Separator
You now can use separator to concatenate multiple items
print("Hello", "Swift", 2, separator:" ")
Both
Or you could combine using in this way
print("Hello", "Swift", 2, separator:" ", terminator:".")
Check it's value
property:
In jQuery (since your tag mentions it):
$('#fileInput').val()
Or in vanilla JavaScript:
document.getElementById('myFileInput').value
$(this.parentNode).addClass('newClass');
Try to use:
Worksheets.Add (After:=Worksheets(Worksheets.Count)).Name = "MySheet"
If you want to check whether a sheet with the same name already exists, you can create a function:
Function funcCreateList(argCreateList)
For Each Worksheet In ThisWorkbook.Worksheets
If argCreateList = Worksheet.Name Then
Exit Function ' if found - exit function
End If
Next Worksheet
Worksheets.Add (After:=Worksheets(Worksheets.Count)).Name = argCreateList
End Function
When the function is created, you can call it from your main Sub, e.g.:
Sub main
funcCreateList "MySheet"
Exit Sub
This worked for me:
ul.dropdown-menu > li {
max-width: 144px;
}
in Chromium and Firefox.
I fixed that on my Windows 10:
Go to Control Panel - Programs and Features - Turn Windows features on or off.
Select .NET Framework 4.6 Advanced Services - WCF Services
Check HTTP Activation.
OK done.
If the date is given in a fixed form, you can simply use a regular expression to extract the date and "datetime.datetime.strptime" to parse the date:
import re
from datetime import datetime
match = re.search(r'\d{4}-\d{2}-\d{2}', text)
date = datetime.strptime(match.group(), '%Y-%m-%d').date()
Otherwise, if the date is given in an arbitrary form, you can't extract it easily.
Few years later, I've built this library to do drop files into any HTML element.
You can use it like
const Droppable = require('droppable');
const droppable = new Droppable({
element: document.querySelector('#my-droppable-element')
})
droppable.onFilesDropped((files) => {
console.log('Files were dropped:', files);
});
// Clean up when you're done!
droppable.destroy();
typename
and class
are interchangeable in the basic case of specifying a template:
template<class T>
class Foo
{
};
and
template<typename T>
class Foo
{
};
are equivalent.
Having said that, there are specific cases where there is a difference between typename
and class
.
The first one is in the case of dependent types. typename
is used to declare when you are referencing a nested type that depends on another template parameter, such as the typedef
in this example:
template<typename param_t>
class Foo
{
typedef typename param_t::baz sub_t;
};
The second one you actually show in your question, though you might not realize it:
template < template < typename, typename > class Container, typename Type >
When specifying a template template, the class
keyword MUST be used as above -- it is not interchangeable with typename
in this case (note: since C++17 both keywords are allowed in this case).
You also must use class
when explicitly instantiating a template:
template class Foo<int>;
I'm sure that there are other cases that I've missed, but the bottom line is: these two keywords are not equivalent, and these are some common cases where you need to use one or the other.
Use Left Outer Join instead of Inner Join to include rows with NULLS.
SELECT Table1.Col1, Table1.Col2, Table1.Col3, Table2.Col4
FROM Table1 LEFT OUTER JOIN
Table2 ON Table1.Col1 = Table2.Col1
AND Table1.Col2 = Table2.Col2

I had the same problem error that is shown, i solve it by adding
defaultConfig {

I had this problem cause i exceeded the 65K methods dex limit imposed by Android i used so many libraries
Add "EntityFramework.SqlServer.dll" into your bin folder. Problem will get resolved.
Just had the same error message, but when I was running a package.json with:
"scripts": {

tsc
is the command to run the TypeScript compiler.
I never had any issues with this project because I had TypeScript installed as a global module. As this project didn't include TypeScript as a dev dependency (and expected it to be installed as global), I had the error when testing in another machine (without TypeScript) and running npm install
didn't fix the problem. So I had to include TypeScript as a dev dependency (npm install typescript --save-dev
) to solve the problem.
This works in MySQL all versions and Amazon RDS Aurora:

This happened to me when I was trying to push the develop branch (I am using git flow). Someone had push updates to master. to fix it I did:
git co master
git pull
Which fetched those changes. Then,
git co develop
git pull
Which didn't do anything. I think the develop branch already pushed despite the error message. Everything is up to date now and no errors.
This is a simplified example with IEnumerable.
I was using two models on the view: a form with search criteria (SearchParams model), and a grid for results, and I struggled with how to add the IEnumerable model and the other model on the same view. Here is what I came up with, hope this helps someone:
@using DelegatePortal.ViewModels;
@model SearchViewModel
@using (Html.BeginForm("Search", "Delegate", FormMethod.Post))
{
Employee First Name
@Html.EditorFor(model => model.SearchParams.FirstName,
new { htmlAttributes = new { @class = "form-control form-control-sm " } })
<input type="submit" id="getResults" value="SEARCH" class="btn btn-primary btn-lg btn-block" />
}
<br />
@(Html
.Grid(Model.Delegates)
.Build(columns =>
{
columns.Add(model => model.Id).Titled("Id").Css("collapse");
columns.Add(model => model.LastName).Titled("Last Name");
columns.Add(model => model.FirstName).Titled("First Name");
})
... )
SearchViewModel.cs:
namespace DelegatePortal.ViewModels
{
public class SearchViewModel
{
public IEnumerable<DelegatePortal.Models.DelegateView> Delegates { get; set; }
public SearchParamsViewModel SearchParams { get; set; }
....
DelegateController.cs:
// GET: /Delegate/Search
public ActionResult Search(String firstName)
{
SearchViewModel model = new SearchViewModel();
model.Delegates = db.Set<DelegateView>();
return View(model);
}
// POST: /Delegate/Search
[HttpPost]
public ActionResult Search(SearchParamsViewModel searchParams)
{
String firstName = searchParams.FirstName;
SearchViewModel model = new SearchViewModel();
if (firstName != null)
model.Delegates = db.Set<DelegateView>().Where(x => x.FirstName == firstName);
return View(model);
}
SearchParamsViewModel.cs:
namespace DelegatePortal.ViewModels
{
public class SearchParamsViewModel
{
public string FirstName { get; set; }
}
}

String str = "";
for(int i=0;i<arg.length();i+=2)

int decimal = Integer.parseInt(s, 16);
str = str + (char) decimal;
}
return str;

If you want to register only one single key press even if the user pressed it for more than once or kept pressing the key longer. To avoid getting multiple pressed inputs use the while loop and pass it.
import keyboard
while(True):
if(keyboard.is_pressed('w')):
s+=1
while(keyboard.is_pressed('w')):
pass
if(keyboard.is_pressed('s')):
s-=1
while(keyboard.is_pressed('s')):
pass
print(s)

returns logical not.The package @angular/router
has the Resolve
property for routes. So you can easily resolve data before rendering a route view.
See: https://angular.io/docs/ts/latest/api/router/index/Resolve-interface.html
Example from docs as of today, August 28, 2017:
class Backend {
fetchTeam(id: string) {
return 'someTeam';
}
}
@Injectable()
class TeamResolver implements Resolve<Team> {
constructor(private backend: Backend) {}
resolve(
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot): Observable<any>|Promise<any>|any {
return this.backend.fetchTeam(route.params.id);
}
}
@NgModule({
imports: [
RouterModule.forRoot([
{
path: 'team/:id',
component: TeamCmp,
resolve: {
team: TeamResolver
}
}
])
],
providers: [TeamResolver]
})
class AppModule {}
Now your route will not be activated until the data has been resolved and returned.
Accessing Resolved Data In Your Component
To access the resolved data from within your component at runtime, there are two methods. So depending on your needs, you can use either:
route.snapshot.paramMap
which returns a string, or the route.paramMap
which returns an Observable you can .subscribe()
to. Example:
// the no-observable method
this.dataYouResolved= this.route.snapshot.paramMap.get('id');
// console.debug(this.licenseNumber);
// or the observable method
this.route.paramMap
.subscribe((params: ParamMap) => {
// console.log(params);
this.dataYouResolved= params.get('id');
return params.get('dataYouResolved');
// return null
});
console.debug(this.dataYouResolved);
I hope that helps.
For the solution in batch. I am using the following command:
FOR /D /R %%G in (obj,bin) DO @IF EXIST %%G IF %%~aG geq d RMDIR /S /Q "%%G"
The reason not using DIR /S /AD /B xxx
1. DIR /S /AD /B obj
will return empty list (at least on my Windows10)
2. DIR /S /AD /B *obj
will contain the result which is not expected (tobj folder)
Something like this will work:
foreach ( Process process in Process.GetProcessesByName( "winword" ) )
{
process.Kill();
process.WaitForExit();
}
You could use CONCAT, and the numeric argument of it is converted to its equivalent binary string form.
select t2.*
from t1 join t2
on t2.url=CONCAT('site.com/path/%', t1.id, '%/more') where t1.id > 9000
Also malloc and realloc are useful if you don't know ahead of time how many strings are being concatenated.
#include <stdio.h>
#include <string.h>
void example(const char *header, const char **words, size_t num_words)
{
size_t message_len = strlen(header) + 1; /* + 1 for terminating NULL */
char *message = (char*) malloc(message_len);
strncat(message, header, message_len);
for(int i = 0; i < num_words; ++i)
{
message_len += 1 + strlen(words[i]); /* 1 + for separator ';' */
message = (char*) realloc(message, message_len);
strncat(strncat(message, ";", message_len), words[i], message_len);
}
puts(message);
free(message);
}
Use DateTime Structure with milliseconds and format like this:
string timestamp = DateTime.UtcNow.ToString("yyyy-MM-dd HH:mm:ss.fff",
CultureInfo.InvariantCulture);
timestamp = timestamp.Replace("-", ".");
You need to use the new android.animation
framework (object animators) with FragmentTransaction.setCustomAnimations
as well as FragmentTransaction.setTransition
.
Here's an example on using setCustomAnimations
from ApiDemos' FragmentHideShow.java:
ft.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out);
and here's the relevant animator XML from res/animator/fade_in.xml:
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:interpolator/accelerate_quad"
android:valueFrom="0"
android:valueTo="1"
android:propertyName="alpha"
android:duration="@android:integer/config_mediumAnimTime" />
Note that you can combine multiple animators using <set>
, just as you could with the older animation framework.
EDIT: Since folks are asking about slide-in/slide-out, I'll comment on that here.
You can of course animate the translationX
, translationY
, x
, and y
properties, but generally slides involve animating content to and from off-screen. As far as I know there aren't any transition properties that use relative values. However, this doesn't prevent you from writing them yourself. Remember that property animations simply require getter and setter methods on the objects you're animating (in this case views), so you can just create your own getXFraction
and setXFraction
methods on your view subclass, like this:
public class MyFrameLayout extends FrameLayout {
...
public float getXFraction() {
return getX() / getWidth(); // TODO: guard divide-by-zero
}
public void setXFraction(float xFraction) {
// TODO: cache width
final int width = getWidth();
setX((width > 0) ? (xFraction * width) : -9999);
}
...
}
Now you can animate the 'xFraction' property, like this:
res/animator/slide_in.xml:
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator"
android:valueFrom="-1.0"
android:valueTo="0"
android:propertyName="xFraction"
android:duration="@android:integer/config_mediumAnimTime" />
Note that if the object you're animating in isn't the same width as its parent, things won't look quite right, so you may need to tweak your property implementation to suit your use case.
The two answers are good. And I also suggest you a similar method:
<% @images.each.with_index do |page, index| %>
<% end %>
You might not see the difference between this and the accepted answer. Let me direct your eyes to these method calls: .each.with_index
see how it's .each
and then .with_index
.
It’s a chicken-and-egg problem. You won’t be able to do it because you need to load the assets to display the progress bar widget, by which time your page will be either fully or partially downloaded. Also, you need to know the total size of the page prior to the user requesting in order to calculate a percentage.
It’s more hassle than it’s worth.
I had a similar problem with truncated tar files being produced by a cron job and redirecting standard out to a file fixed the issue.
From talking to a colleague, cron creates a pipe and limits the amount of output that can be sent to standard out. I fixed mine by removing -v from my tar command, making it much less verbose and keeping the error output in the same spot as the rest of my cron jobs. If you need the verbose tar output, you'll need to redirect to a file, though.
If we need to move from one component to another service then we have to define that service into app.module providers array.
Similarly if you want link through s3Client you can use below.
System.out.println("filelink: " + s3Client.getUrl("your_bucket_name", "your_file_key"));
def get_power_set(s):
power_set=[[]]
for elem in s:
# iterate over the sub sets so far
for sub_set in power_set:
# add a new subset consisting of the subset at hand added elem
power_set=power_set+[list(sub_set)+[elem]]
return power_set
For example:
get_power_set([1,2,3])
yield
[[], [1], [2], [1, 2], [3], [1, 3], [2, 3], [1, 2, 3]]

You can specify a custom class to the top element of the dialog via the option dialogClass
$("#success").dialog({
...
dialogClass:"myClass",
...
});
Then you can target this class in CSS via .myClass.ui-dialog
.
I also had issues in running source

For me, fny answers really got it all. since fetch is not throwing error, we need to throw/handle the error ourselves. Posting my solution with async/await. I think it's more strait forward and readable
Solution 1: Not throwing an error, handle the error ourselves
async _fetch(request) {
const fetchResult = await fetch(request); //Making the req
const result = await fetchResult.json(); // parsing the response
if (fetchResult.ok) {
return result; // return success object
}
const responseError = {
type: 'Error',
message: result.message || 'Something went wrong',
data: result.data || '',
code: result.code || '',
};
const error = new Error();
error.info = responseError;
return (error);
}
Here if we getting an error, we are building an error object, plain JS object and returning it, the con is that we need to handle it outside. How to use:
const userSaved = await apiCall(data); // calling fetch
if (userSaved instanceof Error) {
debug.log('Failed saving user', userSaved); // handle error
return;
}
debug.log('Success saving user', userSaved); // handle success
Solution 2: Throwing an error, using try/catch
async _fetch(request) {
const fetchResult = await fetch(request);
const result = await fetchResult.json();
if (fetchResult.ok) {
return result;
}
const responseError = {
type: 'Error',
message: result.message || 'Something went wrong',
data: result.data || '',
code: result.code || '',
};
let error = new Error();
error = { ...error, ...responseError };
throw (error);
}
Here we are throwing and error that we created, since Error ctor approve only string, Im creating the plain Error js object, and the use will be:
try {
const userSaved = await apiCall(data); // calling fetch
debug.log('Success saving user', userSaved); // handle success
} catch (e) {
debug.log('Failed saving user', userSaved); // handle error
}
Solution 3: Using customer error
async _fetch(request) {
const fetchResult = await fetch(request);
const result = await fetchResult.json();
if (fetchResult.ok) {
return result;
}
throw new ClassError(result.message, result.data, result.code);
}
And:
class ClassError extends Error {
constructor(message = 'Something went wrong', data = '', code = '') {
super();
this.message = message;
this.data = data;
this.code = code;
}
}
Hope it helped.
As asked for by @??s???? an explanation can be found at https://golang.org/pkg/fmt/#Sprint. Related explanations can be found at https://stackoverflow.com/a/44027953/12817546 and at https://stackoverflow.com/a/42302709/12817546. Here is @Yuanbo's answer in full.

str := fmt.Sprint(data)
fmt.Println(str)
}
Simple answer is that you can't - you won't be able to check a for a file on their machine from an ASP website, as to do so would be a dangerous risk for them.
You have to give them a file upload control - and there's not much you can do with that control. For security reasons javascript can't really touch it.
<asp:FileUpload ID="FileUpload1" runat="server" />
They then pick a file to upload, and you have to deal with any empty file that they might send up server side.
The way you take a length of anything for which that makes sense (a list, dictionary, tuple, string, ...) is to call len
on it.
l = [1,2,3,4]
s = 'abcde'
len(l) #returns 4
len(s) #returns 5
The reason for the "strange" syntax is that internally python translates len(object)
into object.__len__()
. This applies to any object. So, if you are defining some class and it makes sense for it to have a length, just define a __len__()
method on it and then one can call len
on those instances.
i want to know if my memory reduction efforts actually help in reducing memory
Following up on this comment, here's what you should do: Try to produce a memory problem - Write code that creates all these objects and graudally increase the upper limit until you ran into a problem (Browser crash, Browser freeze or an Out-Of-memory error). Ideally you should repeat this experiment with different browsers and different operating system.
Now there are two options: option 1 - You didn't succeed in producing the memory problem. Hence, you are worrying for nothing. You don't have a memory issue and your program is fine.
option 2- you did get a memory problem. Now ask yourself whether the limit at which the problem occurred is reasonable (in other words: is it likely that this amount of objects will be created at normal use of your code). If the answer is 'No' then you're fine. Otherwise you now know how many objects your code can create. Rework the algorithm such that it does not breach this limit.
Try $(this).load("/file_name.html");
. This method targets a local file.
You can also target remote files (on another domain) take a look at: http://en.wikipedia.org/wiki/Same_origin_policy
If you want some dynamic sizing in conjunction with a word-wrapping label you can do the following:
Handle the ClientSizeChanged event
for the panel, making the
label fill the space:
private void Panel2_ClientSizeChanged(object sender, EventArgs e)
{
label1.MaximumSize = new Size((sender as Control).ClientSize.Width - label1.Left, 10000);
}
Set Auto-Size
for the label to true
Dock
for the label to Fill
You can either :
Use git stash
to shelve your changes or,
Create another branch and commit your changes there, and then merge that branch into your working directory
Since Java 5 you can use Arrays.toString(arr)
or Arrays.deepToString(arr)
for arrays within arrays. Note that the Object[]
version calls .toString()
on each object in the array. The output is even decorated in the exact way you're asking.
Examples:
String[] array = new String[] {"John", "Mary", "Bob"};
System.out.println(Arrays.toString(array));
Output:
[John, Mary, Bob]
String[][] deepArray = new String[][] {{"John", "Mary"}, {"Alice", "Bob"}};
System.out.println(Arrays.toString(deepArray));
//output: [[Ljava.lang.String;@106d69c, [Ljava.lang.String;@52e922]
System.out.println(Arrays.deepToString(deepArray));
Output:
[[John, Mary], [Alice, Bob]]
double
Array:double[] doubleArray = { 7.0, 9.0, 5.0, 1.0, 3.0 };
System.out.println(Arrays.toString(doubleArray));
Output:
[7.0, 9.0, 5.0, 1.0, 3.0 ]
int
Array:int[] intArray = { 7, 9, 5, 1, 3 };
System.out.println(Arrays.toString(intArray));
Output:
[7, 9, 5, 1, 3 ]
In simple cases you can use next method which doesn`t require you to create a function or to copy code to several cells:
In any cell write next code
=Transpose(A1:A9)
Where A1:A9 are cells you would like to merge.
F9
After that, the cell will contain the string:
={A1,A2,A3,A4,A5,A6,A7,A8,A9}
Source: http://www.get-digital-help.com/2011/02/09/concatenate-a-cell-range-without-vba-in-excel/
Update: One part can be ambiguous. Without leaving the cell means having your cell in editor mode. Alternatevly you can press F9 while are in cell editor panel (normaly it can be found above the spreadsheet)

Apache HttpClient doesn't know anything about JSON, so you'll need to construct your JSON separately. To do so, I recommend checking out the simple JSON-java library from json.org. (If "JSON-java" doesn't suit you, json.org has a big list of libraries available in different languages.)
Once you've generated your JSON, you can use something like the code below to POST it
StringRequestEntity requestEntity = new StringRequestEntity(
JSON_STRING,
"application/json",
"UTF-8");
PostMethod postMethod = new PostMethod("http://example.com/action");
postMethod.setRequestEntity(requestEntity);
int statusCode = httpClient.executeMethod(postMethod);
Edit
Note - The above answer, as asked for in the question, applies to Apache HttpClient 3.1. However, to help anyone looking for an implementation against the latest Apache client:
StringEntity requestEntity = new StringEntity(
JSON_STRING,
ContentType.APPLICATION_JSON);
HttpPost postMethod = new HttpPost("http://example.com/action");
postMethod.setEntity(requestEntity);
HttpResponse rawResponse = httpclient.execute(postMethod);
I use this vanilla JS solution:
const element = document.getElementById('textfield')
element.addEventListener('paste', e => e.preventDefault())
You can do something like this:
File file = new File("Student.txt");
try {
Scanner scanner = new Scanner(file);
//now read the file line by line...
int lineNum = 0;
while (scanner.hasNextLine()) {
String line = scanner.nextLine();
lineNum++;
if(<some condition is met for the line>) {
System.out.println("ho hum, i found it on line " +lineNum);
}
}
} catch(FileNotFoundException e) {
//handle this
}
You may have also put your console.log
after an expectation that fails and is uncaught, so your log line never gets executed.
If you don't want to use list comprehension by some reasons, you can use map and operator.itemgetter:
>>> from operator import itemgetter
>>> rows = [(1, 2), (3, 4), (5, 6)]
>>> map(itemgetter(1), rows)
[2, 4, 6]
>>>

Adding kernel means you want to use Jupyter Notebook
with versions of python which are not showing up in the list.
Simple approach- Start notebook with required python version, suppose I have python3.7
installed then use below command from terminal (cmd) to run notebook:
python3.7 -m notebook
Sometimes instead of python3.7
it's install with alias of py, py3.7, python
.
I came here because I'm new with python and lazy so I was searching an example to create a list of 2 lists, after a while a realized the topic here could be wrong... this is a code to create a list of lists:
listoflists = []
for i in range(0,2):
sublist = []
for j in range(0,10)
sublist.append((i,j))
listoflists.append(sublist)
print listoflists
this the output [ [(0, 0), (0, 1), (0, 2), (0, 3), (0, 4), (0, 5), (0, 6), (0, 7), (0, 8), (0, 9)], [(1, 0), (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (1, 7), (1, 8), (1, 9)] ]
The problem with your code seems to be you are creating a tuple with your list and you get the reference to the list instead of a copy. That I guess should fall under a tuple topic...
Another possible solution, in case the column has not only strings but numbers too, is to use astype(str).str.lower()
or to_string(na_rep='')
because otherwise, given that a number is not a string, when lowered it will return NaN
, therefore:
import pandas as pd
import numpy as np
df=pd.DataFrame(['ONE','Two', np.nan,2],columns=['x'])
xSecureLower = df['x'].to_string(na_rep='').lower()
xLower = df['x'].str.lower()
then we have:
>>> xSecureLower
0 one
1 two
2
3 2
Name: x, dtype: object
and not
>>> xLower
0 one
1 two
2 NaN
3 NaN
Name: x, dtype: object
edit:
if you don't want to lose the NaNs, then using map will be better, (from @wojciech-walczak, and @cs95 comment) it will look something like this
xSecureLower = df['x'].map(lambda x: x.lower() if isinstance(x,str) else x)
convert_to_array = function (sentence) {
return sentence.trim().split(" ");
};
let ages = convert_to_array ("I'm a programmer in javascript writing script");
function confirmEnding(string) {
let target = "ipt";
return (string.substr(-target.length) === target) ? true : false;
}
function mySearchResult() {
return ages.filter(confirmEnding);
}
mySearchResult();
you could check like this and return an array of the matched words using filter
You can use kill -0
for checking whether a particular pid is running or not.
Assuming, you have list of pid
numbers in a file called pid
in pwd
while true;
do
if [ -s pid ] ; then
for pid in `cat pid`
do
echo "Checking the $pid"
kill -0 "$pid" 2>/dev/null || sed -i "/^$pid$/d" pid
done
else
echo "All your process completed" ## Do what you want here... here all your pids are in finished stated
break
fi
done
Guess you just missed the find method in the docs:
my_array.find {|e| e.satisfies_condition? }
Like you said since the xpath for the next button is the same on every page it won't work. It's working as coded in that it does wait for the element to be displayed but since it's already displayed then the implicit wait doesn't apply because it doesn't need to wait at all. Why don't you use the fact that the url changes since from your code it appears to change when the next button is clicked. I do C# but I guess in Java it would be something like:
WebDriver driver = new FirefoxDriver();
String startURL = //a starting url;
String currentURL = null;
WebDriverWait wait = new WebDriverWait(driver, 10);
foo(driver,startURL);
/* go to next page */
if(driver.findElement(By.xpath("//*[@id='someID']")).isDisplayed()){
String previousURL = driver.getCurrentUrl();
driver.findElement(By.xpath("//*[@id='someID']")).click();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
ExpectedCondition e = new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver d) {
return (d.getCurrentUrl() != previousURL);
}
};
wait.until(e);
currentURL = driver.getCurrentUrl();
System.out.println(currentURL);
}
We control fork() process call by if, else statement. See my code below:
int main()
{
int forkresult, parent_ID;
forkresult=fork();
if(forkresult !=0 )
{
printf(" I am the parent my ID is = %d" , getpid());
printf(" and my child ID is = %d\n" , forkresult);
}
parent_ID = getpid();
if(forkresult ==0)
printf(" I am the child ID is = %d",getpid());
else
printf(" and my parent ID is = %d", parent_ID);
}
In recent Oracle versions the COST represent the amount of time that the optimiser expects the query to take, expressed in units of the amount of time required for a single block read.
So if a single block read takes 2ms and the cost is expressed as "250", the query could be expected to take 500ms to complete.
The optimiser calculates the cost based on the estimated number of single block and multiblock reads, and the CPU consumption of the plan. the latter can be very useful in minimising the cost by performing certain operations before others to try and avoid high CPU cost operations.
This raises the question of how the optimiser knows how long operations take. recent Oracle versions allow the collections of "system statistics", which are definitely not to be confused with statistics on tables or indexes. The system statistics are measurements of the performance of the hardware, mostly importantly:
These numbers can vary greatly according to the operating environment of the system, and different sets of statistics can be stored for "daytime OLTP" operations and "nighttime batch reporting" operations, and for "end of month reporting" if you wish.
Given these sets of statistics, a given query execution plan can be evaluated for cost in different operating environments, which might promote use of full table scans at some times or index scans at others.
The cost is not perfect, but the optimiser gets better at self-monitoring with every release, and can feedback the actual cost in comparison to the estimated cost in order to make better decisions for the future. this also makes it rather more difficult to predict.
Note that the cost is not necessarily wall clock time, as parallel query operations consume a total amount of time across multiple threads.
In older versions of Oracle the cost of CPU operations was ignored, and the relative costs of single and multiblock reads were effectively fixed according to init parameters.
Simply do:
grouped_df = df.groupby('A')
for key, item in grouped_df:
print(grouped_df.get_group(key), "\n\n")
This also works,
grouped_df = df.groupby('A')
gb = grouped_df.groups
for key, values in gb.iteritems():
print(df.ix[values], "\n\n")
For selective key grouping: Insert the keys you want inside the key_list_from_gb
, in following, using gb.keys()
: For Example,
gb = grouped_df.groups
gb.keys()
key_list_from_gb = [key1, key2, key3]
for key, values in gb.items():
if key in key_list_from_gb:
print(df.ix[values], "\n")
There are some perfectly capable answers here. However for non-trivial script it may be desirable to retain the code in a cache, or for debugging purposes, or even to have dynamically self-updating code.
To that end, sometimes it's simpler or more robust to interact with Java via command line. Create a temporary directory, output your script and any assets, create the jar. Finally import your new code.
It's a bit beyond the scope of normal eval()
use in most languages, though you could certainly implement eval by returning the result from some function in your jar.
Still, thought I'd mention this method as it does fully encapsulate everything Java can do without 3rd party tools, in case of desperation. This method allows me to turn HTML templates into objects and save them, avoiding the need to parse a template at runtime.
Here is the method by using explode
:
$text = explode('_', '233718_This_is_a_string', 2)[1]; // Returns This_is_a_string
or:
$text = @end((explode('_', '233718_This_is_a_string', 2)));
By specifying 2
for the limit
parameter in explode()
, it returns array with 2 maximum elements separated by the string delimiter. Returning 2nd element ([1]
), will give the rest of string.
Here is another one-liner by using strpos
(as suggested by @flu):
$needle = '233718_This_is_a_string';
$text = substr($needle, (strpos($needle, '_') ?: -1) + 1); // Returns This_is_a_string
The problem is what happens when you get NumberFormatexception
thrown? You print it and return nothing.
Note: You don't need to catch and throw an Exception back. Usually it is done to wrap it or print stack trace and ignore for example.
catch(RangeException e) {
throw e;
}
From the source code:
// Instance of WebViewClient that is the client callback.
private volatile WebViewClient mWebViewClient;
// Instance of WebChromeClient for handling all chrome functions.
private volatile WebChromeClient mWebChromeClient;
// SOME OTHER SUTFFF.......
/**
* Set the WebViewClient.
* @param client An implementation of WebViewClient.
*/
public void setWebViewClient(WebViewClient client) {
mWebViewClient = client;
}
/**
* Set the WebChromeClient.
* @param client An implementation of WebChromeClient.
*/
public void setWebChromeClient(WebChromeClient client) {
mWebChromeClient = client;
}
Using WebChromeClient allows you to handle Javascript dialogs, favicons, titles, and the progress. Take a look of this example: Adding alert() support to a WebView
At first glance, there are too many differences WebViewClient & WebChromeClient. But, basically: if you are developing a WebView that won't require too many features but rendering HTML, you can just use a WebViewClient
. On the other hand, if you want to (for instance) load the favicon of the page you are rendering, you should use a WebChromeClient
object and override the onReceivedIcon(WebView view, Bitmap icon)
.
Most of the times, if you don't want to worry about those things... you can just do this:
webView= (WebView) findViewById(R.id.webview);
webView.setWebChromeClient(new WebChromeClient());
webView.setWebViewClient(new WebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
And your WebView will (in theory) have all features implemented (as the android native browser).
If you dont find Hyper-V option in control panel as said in other responses here, try entering BIOS setup (restarting and pressing F-12 or ESC or other depending on your PC) and enabling Virtualization, located probably in CPU options.
You can use Id of the field as well
$('#checkbox1').change(function() {
if($(this).is(":checked")) {
//'checked' event code
return;
}
//'unchecked' event code
});
You will need to do an Ajax call I suspect. Here is an example of an Ajax called made by jQuery to get you started. The Code logs in a user to my system but returns a bool as to whether it was successful or not. Note the ScriptMethod and WebMethod attributes on the code behind method.
in markup:
var $Username = $("#txtUsername").val();
var $Password = $("#txtPassword").val();
//Call the approve method on the code behind
$.ajax({
type: "POST",
url: "Pages/Mobile/Login.aspx/LoginUser",
data: "{'Username':'" + $Username + "', 'Password':'" + $Password + "' }", //Pass the parameter names and values
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
error: function (jqXHR, textStatus, errorThrown) {
alert("Error- Status: " + textStatus + " jqXHR Status: " + jqXHR.status + " jqXHR Response Text:" + jqXHR.responseText) },
success: function (msg) {
if (msg.d == true) {
window.location.href = "Pages/Mobile/Basic/Index.aspx";
}
else {
//show error
alert('login failed');
}
}
});
In Code Behind:
/// <summary>
/// Logs in the user
/// </summary>
/// <param name="Username">The username</param>
/// <param name="Password">The password</param>
/// <returns>true if login successful</returns>
[WebMethod, ScriptMethod]
public static bool LoginUser( string Username, string Password )
{
try
{
StaticStore.CurrentUser = new User( Username, Password );
//check the login details were correct
if ( StaticStore.CurrentUser.IsAuthentiacted )
{
//change the status to logged in
StaticStore.CurrentUser.LoginStatus = Objects.Enums.LoginStatus.LoggedIn;
//Store the user ID in the list of active users
( HttpContext.Current.Application[ SessionKeys.ActiveUsers ] as Dictionary<string, int> )[ HttpContext.Current.Session.SessionID ] = StaticStore.CurrentUser.UserID;
return true;
}
else
{
return false;
}
}
catch ( Exception ex )
{
return false;
}
}
Because HTTP is stateless, in order to associate a request to any other request, you need a way to store user data between HTTP requests.
Cookies or URL parameters ( for ex. like http://example.com/myPage?asd=lol&boo=no ) are both suitable ways to transport data between 2 or more request. However they are not good in case you don't want that data to be readable/editable on client side.
The solution is to store that data server side, give it an "id", and let the client only know (and pass back at every http request) that id. There you go, sessions implemented. Or you can use the client as a convenient remote storage, but you would encrypt the data and keep the secret server-side.
Of course there are other aspects to consider, like you don't want people to hijack other's sessions, you want sessions to not last forever but to expire, and so on.
In your specific example, the user id (could be username or another unique ID in your user database) is stored in the session data, server-side, after successful identification. Then for every HTTP request you get from the client, the session id (given by the client) will point you to the correct session data (stored by the server) that contains the authenticated user id - that way your code will know what user it is talking to.

Now, create new folder and copy “classes.dex.dex2jar.jar” into it.
Unzip “jd-gui-0.3.3.linux.i686.zip“ and open up the “Java Decompiler” in full screen mode.
Click on open file and select “classes.dex.dex2jar.jar” into the window.
“Java Decompiler” and go to file > save and save the source in a .zip file.
Create “source_code” folder.
Extract the saved .zip and copy the contents to “source_code” folder.
This will be where we keep your source code.
Extract apktool1.5.1.tar.bz2 , you get apktool.jar
Now, unzip “apktool-install-linux-r05-ibot.zip”
Copy “framework-res.apk” , “.apk” and apktool.jar
Paste it to the unzip “apktool-install-linux-r05-ibot” folder (line no 13).
Then open terminal and type:
– cd
– chown -R : ‘apktool.jar’
– chown -R : ‘apktool’
– chown -R : ‘aapt’
– sudo chmod +x ‘apktool.jar’
– sudo chmod +x ‘apktool’
– sudo chmod +x ‘aapt’
– sudo mv apktool.jar /usr/local/bin
– sudo mv apktool /usr/local/bin
– sudo mv aapt /usr/local/bin
– apktool if framework-res.apk – apktool d .apk

Sachin Tendulkar has been the most complete batsman of his time, the most prolific runmaker of all time, and arguably the biggest cricket icon the game has ever known. His batting is based on the purest principles: perfect balance, economy of movement, precision in stroke-making.

For Eclipse Mars (I've just verified that) you to do this (assuming that C:\eclipseMarsEE is root folder of your Eclipse):
Here is how you can scale it easily.
This works in 2.x with the Simulator and the iPhone.
UIImage *thumbnail = [originalImage _imageScaledToSize:CGSizeMake(40.0, 40.0) interpolationQuality:1];
After you connect the UIButton that you want to change its background as an OUtlet to your ViewController.swift file you can use the following:
yourUIButton.backgroundColor = UIColor.blue
First, I would like to clarify something. Is this a post back (trip back to server) never occur, or is it the post back occurs, but it never gets into the ddlCountry_SelectedIndexChanged event handler?
I am not sure which case you are having, but if it is the second case, I can offer some suggestion. If it is the first case, then the following is FYI.
For the second case (event handler never fires even though request made), you may want to try the following suggestions:
Beware that when calling Control.DataBind(), view state and post back information would no longer be available from the control. In the case of view state is on, between post back, values of the DropDownList would be kept intact (the list does not to be rebound). If you issue another DataBind in OnLoad, it would clear out its view state data, and the SelectedIndexChanged event would never be fired.
In the case of view state is turned off, you have no choice but to rebind the list every time. When a post back occurs, there are internal ASP.NET calls to populate the value from Request.Params to the appropriate controls, and I suspect happen at the time between OnInit and OnLoad. In this case, restoring the list values in OnInit will enable the system to fire events correctly.
Thanks for your time reading this, and welcome everyone to correct if I am wrong.
make these changes in your div's style
z-index:100;
some higher value makes sure that this element is above allposition:fixed;
this makes sure that even if scrolling is done, div lies on top and always visible
Regarding some points mentioned in previous answers, and to improve readability:
No need for data.loc or query, but I do think it is a bit long.
The parentheses are also necessary, because of the precedence of the & operator vs. the comparison operators.
I like to write such expressions as follows - less brackets, faster to type, easier to read. Closer to R, too.
q_product = df.Product == p_id
q_start = df.Time > start_time
q_end = df.Time < end_time
df.loc[q_product & q_start & q_end, c('Time,Product')]
# c is just a convenience
c = lambda v: v.split(',')
textarea {
border: 0;
overflow: auto; }
less CSS ^ you can't align the text to the bottom unfortunately.
From RFC 1945 (HTTP/1.0) and RFC 2617 (HTTP Authentication referenced by HTTP/1.1)
The realm attribute (case-insensitive) is required for all authentication schemes which issue a challenge. The realm value (case-sensitive), in combination with the canonical root URL of the server being accessed, defines the protection space. These realms allow the protected resources on a server to be partitioned into a set of protection spaces, each with its own authentication scheme and/or authorization database. The realm value is a string, generally assigned by the origin server, which may have additional semantics specific to the authentication scheme.
In short, pages in the same realm should share credentials. If your credentials work for a page with the realm "My Realm", it should be assumed that the same username and password combination should work for another page with the same realm.

Including javascript files inside javascript files
In short you can load the script file with AJAX or put a script tag on the HTML to include it( before the script that uses the functions of the other script). The link I posted is a great answer and has multiple examples and explanations of both methods.
If you want to completely destroy the target, you have a couple of options. First you can remove the object from the DOM as described above...
console.log($target); // jQuery object
$target.remove(); // remove target from the DOM
console.log($target); // $target still exists
Option 1 - Then replace target with an empty jQuery object (jQuery 1.4+)
$target = $();
console.log($target); // empty jQuery object
Option 2 - Or delete the property entirely (will cause an error if you reference it elsewhere)
delete $target;
console.log($target); // error: $target is not defined
More reading: info about empty jQuery object, and info about delete
If aim is to create a resources folder parallel to src/main/java, then do the following:
Right Click on your project > New > Source Folder
Provide Folder Name as src/main/resources
Finish
The second method would almost certainly be the fastest way to test whether a null-terminated string is empty, since it involves one read and one comparison. There's certainly nothing wrong with this approach in this case, so you may as well use it.
The third method doesn't check whether a character array is empty; it ensures that a character array is empty.
This issue appears to be causing ongoing consternation, so I will attempt to give a clearer answer than the previously posted answers, which only contain partial hints as to what's happening.
Rosetta Flash
that demonstrated a way for hackers to run malicious Flash SWF files from a remote domain in a manner which tricks browsers into thinking it came from the same domain the user was currently browsing. This allows bypassing of the "same-origin policy" and can permit hackers a variety of exploits. You can read the details here: https://miki.it/blog/2014/7/8/abusing-jsonp-with-rosetta-flash/
Content-Disposition: attachment; filename=f.txt
on the returns from JSONP endpoints. This has the annoyance of causing the browser to automatically download a file called f.txt
that you didn't request—but it is far better than your browser automatically running a possibly malicious Flash file.ad.doubleclick.net
probably serves out hundreds of thousands of different ads and only a small percentage likely contain malicious content. This is why various users online are confused thinking they fixed the issue or somehow affected it by uninstalling this program or running that scan, when in fact it is all unrelated. The f.txt
download just means you were protected from a recent potential attack with this exploit and you should have no reason to believe you were compromised in any way.f.txt
file from being downloaded again in the future would be to block the most common domains that appear to be serving this exploit. I've put a short list below of some of the ones implicated in various posts. If you wanted to block these domains from touching your computer, you could add them to your firewall or alternatively you could use the HOSTS
file technique described in the second section of this link: http://www.chromefans.org/chrome-tutorial/how-to-block-a-website-in-google-chrome.htmad.doubleclick.net

One good place to use a goto is in a procedure that can abort at several points, each of which requires various levels of cleanup. Gotophobes can always replace the gotos with structured code and a series of tests, but I think this is more straightforward because it eliminates excessive indentation:
if (!openDataFile()) goto quit; if (!getDataFromFile()) goto closeFileAndQuit; if (!allocateSomeResources) goto freeResourcesAndQuit; // Do more work here.... freeResourcesAndQuit: // free resources closeFileAndQuit: // close file quit: // quit!
Code bellow may help if you want to exclude boolean type from serialization either:
