I solved the simmilar problem, when i tried to push to repo via gitlab ci/cd pipeline by the command "gem install rake && bundle install"
The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.
sudo apt-get install ruby-all-dev
worked for me.
The creation of pdf-documents with the rails-latex-gem
lead to a similar problem.
I solved this by modifying layouts/application.pdf.erb
to
\begin{document}
<%= yield.force_encoding("UTF-8") %>

Webdriver doesn't contain an API to do it. See issue 141 from Selenium tracker for more info. The title of the issue says that it's about response headers but it was decided that Selenium won't contain API for request headers in scope of this issue. Several issues about adding API to set request headers have been marked as duplicates: first, second, third.
Here are a couple of possibilities that I can propose:
I'd go with option 3 in most of cases. It's not hard.
Note that Ghostdriver has an API for it but it's not supported by other drivers.
You could count with sql and retrieve the answer from the resultset like so:
Statment stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
ResultSet ct = stmt.executeQuery("SELECT COUNT(*) FROM [table_name]");
if(ct.next()){
td.setTotalNumRows(ct.getInt(1));
}
Here I'm counting everything but you can easily modify the SQL to count based on a criteria.
I'm using a logger_config.yaml
file to configure my logging, and to get those logs to show up, all I had to do was to add a disable_existing_loggers: False
to the end of it.
My logging setup is rather extensive and confusing, so I don't even know a good way to explain it here, but if someone's also using a YAML file to configure their logging, this might help.
https://docs.python.org/3/howto/logging.html#configuring-logging
This maybe due to an incorrect table name from where you are fetching the data. Please verify the name of the table you mentioned in asmx file and the table created in database.
It means 'not equal to'. So you're filtering out records where ordid
is 605. Overall you're looking for any records which have the same prodid
and qty
values as those assigned to ordid
605, but which are for a different order.
If you simply want to initialise a member field or property with the constructor parameter, in C# >= 3 you can do it very easier:
public static string GetAllItems<T>(...) where T : InterfaceOrBaseClass, new()
{
...
List<T> tabListItems = new List<T>();
foreach (ListItem listItem in listCollection)
{
tabListItems.Add(new T{ BaseMemberItem = listItem }); // No error, BaseMemberItem owns to InterfaceOrBaseClass.
}
...
}
This is the same thing Garry Shutler said, but I'd like to put an aditional note.
Of course you can use a property trick to do more stuff than just setting a field value. A property "set()" can trigger any processing needed to setup its related fields and any other need for the object itself, including a check to see if a full initialization is to take place before the object is used, simulating a full contruction (yes, it is an ugly workaround, but it overcomes M$'s new() limitation).
I can't be assure if it is a planned hole or an accidental side effect, but it works.
It is very funny how MS people adds new features to the language and seems to not do a full side effects analysis. The entire generic thing is a good evidence of this...
What I was looking for was this:
git diff <ref1>..<ref2> <dirname>
Use lodash's groupby
method
Creates an object composed of keys generated from the results of running each element of collection thru iteratee. The order of grouped values is determined by the order they occur in collection. The corresponding value of each key is an array of elements responsible for generating the key. The iteratee is invoked with one argument: (value).
So with lodash you can get what you want in a single line. See below
let myArray = [_x000D_
{group: "one", color: "red"},_x000D_
{group: "two", color: "blue"},_x000D_
{group: "one", color: "green"},_x000D_
{group: "one", color: "black"},_x000D_
]_x000D_
let grouppedArray=_.groupBy(myArray,'group')_x000D_
console.log(grouppedArray)
_x000D_

If you want a Popup that closes automatically, you should look for Toasts. But if you want a dialog that the user has to close first before proceeding, you should look for a Dialog.
For both approaches it is possible to read a text file with the text you want to display. But you could also hardcode the text or use R.String to set the text.
It is possible for the TCP socket to be "closing" and your code to not have yet been notified.
Here is a animation for the life cycle. http://tcp.cs.st-andrews.ac.uk/index.shtml?page=connection_lifecycle
Basically, the connection was closed by the client. You already have throws IOException
and SocketException
extends IOException
. This is working just fine. You just need to properly handle IOException
because it is a normal part of the api.
EDIT: The RST
packet occurs when a packet is received on a socket which does not exist or was closed. There is no difference to your application. Depending on the implementation the reset
state may stick and closed
will never officially occur.
Try this:
int index = row.Table.Columns["ColumnName"].Ordinal;
I'd just like to point out a third alternative which also works if the cursor is not at the start position:
if (cursor.moveToFirst()) {
do {
// do what you need with the cursor here
} while (cursor.moveToNext());
}
A riot.js solution:
My riot.js Example nests the animated-modal tag inside an order profile tag.
Note, this assumes jquery and riot.js is loaded before.

A matrix is actually an array of arrays.
int rows = ..., cols = ...;
int** matrix = new int*[rows];
for (int i = 0; i < rows; ++i)
matrix[i] = new int[cols];
Of course, to delete the matrix, you should do the following:
for (int i = 0; i < rows; ++i)
delete [] matrix[i];
delete [] matrix;
I have just figured out another possibility:
int rows = ..., cols = ...;
int** matrix = new int*[rows];
if (rows)
{
matrix[0] = new int[rows * cols];
for (int i = 1; i < rows; ++i)
matrix[i] = matrix[0] + i * cols;
}
Freeing this array is easier:
if (rows) delete [] matrix[0];
delete [] matrix;
This solution has the advantage of allocating a single big block of memory for all the elements, instead of several little chunks. The first solution I posted is a better example of the arrays of arrays concept, though.
Specify POST method in form
<form name="registrationform" action="register.php" method="post">
your form code
</form>
Let's say you have two models, one named Person and another one named Companies.
By definition, one person can create more than one company.
Considering a company can have one and only one person, we want that when a person is deleted that all the companies associated with that person also be deleted.
So, we start by creating a Person model, like this
class Person(models.Model):
id = models.IntegerField(primary_key=True)
name = models.CharField(max_length=20)
def __str__(self):
return self.id+self.name
Then, the Companies model can look like this
class Companies(models.Model):
title = models.CharField(max_length=20)
description=models.CharField(max_length=10)
person= models.ForeignKey(Person,related_name='persons',on_delete=models.CASCADE)
Notice the usage of on_delete=models.CASCADE
in the model Companies. That is to delete all companies when the person that owns it (instance of class Person) is deleted.

Handling database versions is very important part of application development. I assume that you already have class AppDbHelper extending SQLiteOpenHelper
. When you extend it you will need to implement onCreate
and onUpgrade
method.
When onCreate
and onUpgrade
methods called
onCreate
called when app newly installed.onUpgrade
called when app updated. Organizing Database versions
I manage versions in a class methods. Create implementation of interface Migration. E.g. For first version create MigrationV1
class, second version create MigrationV1ToV2
(these are my naming convention)
public interface Migration {
void run(SQLiteDatabase db);//create tables, alter tables
}
Example migration:
public class MigrationV1ToV2 implements Migration{
public void run(SQLiteDatabase db){
//create new tables
//alter existing tables(add column, add/remove constraint)
//etc.
}
}
onCreate
: Since onCreate
will be called when application freshly installed, we also need to execute all migrations(database version updates). So onCreate
will looks like this:
public void onCreate(SQLiteDatabase db){
Migration mV1=new MigrationV1();
//put your first database schema in this class
mV1.run(db);
Migration mV1ToV2=new MigrationV1ToV2();
mV1ToV2.run(db);
//other migration if any
}
onUpgrade
: This method will be called when application is already installed and it is updated to new application version. If application contains any database changes then put all database changes in new Migration class and increment database version.
For example, lets say user has installed application which has database version 1, and now database version is updated to 2(all schema updates kept in MigrationV1ToV2
). Now when application upgraded, we need to upgrade database by applying database schema changes in MigrationV1ToV2
like this:
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
if (oldVersion < 2) {
//means old version is 1
Migration migration = new MigrationV1ToV2();
migration.run(db);
}
if (oldVersion < 3) {
//means old version is 2
}
}
Note: All upgrades (mentioned in
onUpgrade
) in to database schema should be executed inonCreate
I was facing same error, But I didn't need to change my password.
Just go to bitbucket->preferences->accounts
select your account and check if your password is correct.
In my case, my password was messed up. Just corrected my password and it worked.
I made a registry (.reg) file that will automatically change the registry for you. It works if it's installed in "C:\Python27":
Download 32-bit version HKEY_LOCAL_MACHINE|HKEY_CURRENT_USER\SOFTWARE\wow6432node\
Download 64-bit version HKEY_LOCAL_MACHINE|HKEY_CURRENT_USER\SOFTWARE\
Try this
<input type="checkbox" style="zoom:1.5;" />
/* The value 1.5 i.e., the size of checkbox will be increased by 0.5% */
system
The system
method calls a system program. You have to provide the command as a string argument to this method. For example:
>> system("date")
Wed Sep 4 22:03:44 CEST 2013
=> true
The invoked program will use the current STDIN
, STDOUT
and STDERR
objects of your Ruby program. In fact, the actual return value is either true
, false
or nil
. In the example the date was printed through the IO object of STDIN
. The method will return true
if the process exited with a zero status, false
if the process exited with a non-zero status and nil
if the execution failed.
As of Ruby 2.6, passing exception: true
will raise an exception instead of returning false
or nil
:
>> system('invalid')
=> nil
>> system('invalid', exception: true)
Traceback (most recent call last):
...
Errno::ENOENT (No such file or directory - invalid)
Another side effect is that the global variable $?
is set to a Process::Status
object. This object will contain information about the call itself, including the process identifier (PID) of the invoked process and the exit status.
>> system("date")
Wed Sep 4 22:11:02 CEST 2013
=> true
>> $?
=> #<Process::Status: pid 15470 exit 0>
Backticks
Backticks (``) call a system program and return its output. As opposed to the first approach, the command is not provided through a string, but by putting it inside a backticks pair.
>> `date`
=> Wed Sep 4 22:22:51 CEST 2013
The global variable $?
is set through the backticks, too. With backticks you can also make use string interpolation.
%x()
Using %x
is an alternative to the backticks style. It will return the output, too. Like its relatives %w
and %q
(among others), any delimiter will suffice as long as bracket-style delimiters match. This means %x(date)
, %x{date}
and %x-date-
are all synonyms. Like backticks %x
can make use of string interpolation.
exec
By using Kernel#exec
the current process (your Ruby script) is replaced with the process invoked through exec
. The method can take a string as argument. In this case the string will be subject to shell expansion. When using more than one argument, then the first one is used to execute a program and the following are provided as arguments to the program to be invoked.
Open3.popen3
Sometimes the required information is written to standard input or standard error and you need to get control over those as well. Here Open3.popen3
comes in handy:
require 'open3'
Open3.popen3("curl http://example.com") do |stdin, stdout, stderr, thread|
pid = thread.pid
puts stdout.read.chomp
end
Check into this thread,. However you should be careful as it's documented as "can change upon factory reset". Use at your own risk, and it can be easily changed on a rooted phone. Also it appears as if some manufacturers have had issues with their phones having duplicate numbers thread. Depending on what your trying to do, I probably wouldnt use this as a UID.
If you use svn+ssh, you can copy your public ssh key to the remote machine:
ssh-copy-id user@remotehost
For Java, check out chapter 12 of JCIP. There are some concrete examples of writing deterministic, multi-threaded unit tests to at least test the correctness and invariants of concurrent code.
"Proving" thread-safety with unit tests is much dicier. My belief is that this is better served by automated integration testing on a variety of platforms/configurations.
A friend showed me how to do this as follows:
"./" works when the file requesting the image (e.g., "example.js") is on the same level within the folder tree structure as the folder "images".
Or if you use gmaps.js, call:
map.refresh();
when your div is shown.
The normal usage of static is to access the function directly with out any object creation. Same as in java main we could not create any object for that class to invoke the main method. It will execute automatically. If we want to execute manually we can call by using main() inside the class and ClassName.main from outside the class.
var dataString = "flag=fetchmediaaudio&id="+id;
$.ajax
({
type: "POST",
url: "ajax.php",
data: dataString,
success: function(html)
{
alert(html);
}
});
It's easier to ask forgiveness than ask permission. Simply perform the operation. If it works, the object was of an acceptable, suitable, proper type. If the operation doesn't work, the object was not of a suitable type. Knowing the type rarely helps.
Simply attempt the operation and see if it works.

Bullets take the color
property of the list:
.listStyle {
color: red;
}
Note if you want your list text to be a different colour, you have to wrap it in say, a p
, for example:
.listStyle p {
color: black;
}
<ul class="listStyle">
<li>
<p><strong>View :</strong> blah blah.</p>
</li>
<li>
<p><strong>View :</strong> blah blah.</p>
</li>
</ul>
In .Net Core (NetCore) use the following syntax to change the timeout from the default 30 seconds to 90 seconds:
public class DataContext : DbContext
{
public DataContext(DbContextOptions<DataContext> options) : base(options)
{
this.Database.SetCommandTimeout(90); // <-- 90 seconds
}
}
Another solution is to use the address
http://localhost:8732/Design_Time_Addresses/YOUR_ADDRESS .
.NET Framework (3.5) automatically register this address (http://*:8732/Design_Time_Addresses) for debugging scope. This is useful when you need to host services inside visual studio for debugging or testing. Don't use this on production...
I've come up with the following method, which works for me because in every case the model will have a ModelForm associated with it.
def GetModelData(form, fields):
"""
Extract data from the bound form model instance and return a
dictionary that is easily usable in templates with the actual
field verbose name as the label, e.g.
model_data{"Address line 1": "32 Memory lane",
"Address line 2": "Brainville",
"Phone": "0212378492"}
This way, the template has an ordered list that can be easily
presented in tabular form.
"""
model_data = {}
for field in fields:
model_data[form[field].label] = eval("form.data.%s" % form[field].name)
return model_data
@login_required
def clients_view(request, client_id):
client = Client.objects.get(id=client_id)
form = AddClientForm(client)
fields = ("address1", "address2", "address3", "address4",
"phone", "fax", "mobile", "email")
model_data = GetModelData(form, fields)
template_vars = RequestContext(request,
{
"client": client,
"model_data": model_data
}
)
return render_to_response("clients-view.html", template_vars)
Here is an extract from the template I am using for this particular view:
<table class="client-view">
<tbody>
{% for field, value in model_data.items %}
<tr>
<td class="field-name">{{ field }}</td><td>{{ value }}</td>
</tr>
{% endfor %}
</tbody>
</table>
The nice thing about this method is that I can choose on a template-by-template basis the order in which I would like to display the field labels, using the tuple passed in to GetModelData and specifying the field names. This also allows me to exclude certain fields (e.g. a User foreign key) as only the field names passed in via the tuple are built into the final dictionary.
I'm not going to accept this as the answer because I'm sure someone can come up with something more "Djangonic" :-)
Update: I'm choosing this as the final answer because it is the simplest out of those given that does what I need. Thanks to everyone who contributed answers.
Alternative way for "insufficient string length or null" save:
String numbers = defaultValue();
try{
numbers = word.substring(word.length() - 3);
} catch(Exception e) {
System.out.println("Insufficient String length");

Spring Data JPA supports a large number of keywords to build a query. IN
and AND
are among them.
Use combine
from moreutils
package, a sets utility that supports not
, and
, or
, xor
operations
combine file1 not file2
i.e give me lines that are in file1 but not in file2
OR give me lines in file1 minus lines in file2
Note: combine
sorts and finds unique lines in both files before performing any operation but diff
does not. So you might find differences between output of diff
and combine
.
So in effect you are saying
Find distinct lines in file1 and file2 and then give me lines in file1 minus lines in file2
In my experience, it's much faster than other options
What you have is correct, but this is more consice:
^[A-Z]{3}$
Since it wouldn't add any value to repeat that it means echo
, I thought you'd like to see what means in PHP exactly:
Array
(
[0] => Array
(
[0] => 368 // T_OPEN_TAG_WITH_ECHO
[1] => <?=
[2] => 1
)
[1] => Array
(
[0] => 309 // T_VARIABLE
[1] => $a
[2] => 1
)
[2] => ; // UNKNOWN (because it is optional (ignored))
[3] => Array
(
[0] => 369 // T_CLOSE_TAG
[1] => ?>
[2] => 1
)
)
You can use this code to test it yourself:
$tokens = token_get_all('<?=$a;?>');
print_r($tokens);
foreach($tokens as $token){
echo token_name((int) $token[0]), PHP_EOL;
}
From the List of Parser Tokens, here is what T_OPEN_TAG_WITH_ECHO links to.

As with all date manipulation you have to use NSDateComponents and NSCalendar
NSDate *now = [NSDate date];
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier: NSCalendarIdentifierGregorian];
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay fromDate:now];
[components setHour:10];
NSDate *today10am = [calendar dateFromComponents:components];
in iOS8 Apple introduced a convenience method that saves a few lines of code:
NSDate *d = [calendar dateBySettingHour:10 minute:0 second:0 ofDate:[NSDate date] options:0];
Swift:
let calendar: NSCalendar! = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
let now: NSDate! = NSDate()
let date10h = calendar.dateBySettingHour(10, minute: 0, second: 0, ofDate: now, options: NSCalendarOptions.MatchFirst)!
A virtual function makes its class a polymorphic base class. Derived classes can override virtual functions. Virtual functions called through base class pointers/references will be resolved at run-time. That is, the dynamic type of the object is used instead of its static type:
Derived d;
Base& rb = d;
// if Base::f() is virtual and Derived overrides it, Derived::f() will be called
rb.f();
A pure virtual function is a virtual function whose declaration ends in =0
:
class Base {
// ...
virtual void f() = 0;
// ...
A pure virtual function implicitly makes the class it is defined for abstract (unlike in Java where you have a keyword to explicitly declare the class abstract). Abstract classes cannot be instantiated. Derived classes need to override/implement all inherited pure virtual functions. If they do not, they too will become abstract.
An interesting 'feature' of C++ is that a class can define a pure virtual function that has an implementation. (What that's good for is debatable.)
Note that C++11 brought a new use for the delete
and default
keywords which looks similar to the syntax of pure virtual functions:
my_class(my_class const &) = delete;
my_class& operator=(const my_class&) = default;
See this question and this one for more info on this use of delete
and default
.
There's been a fair amount of recent research in considering how REST HTTP calls could replace the message queue concept.
If you introduce the concept of a process and a task as a resource, the need for middle messaging layer starts to evaporate.
Ex:
POST /task/name
- Returns a 202 accepted status immediately
- Returns a resource url for the created task: /task/name/X
- Returns a resource url for the started process: /process/Y
GET /process/Y
- Returns status of ongoing process
A task can have multiple steps for initialization, and a process can return status when polled or POST to a callback URL when complete.
This is dead simple, and becomes quite powerful when you realize that you can now subscribe to an rss/atom feed of all running processes and tasks without any middle layer. Any queuing system is going to require some sort of web front end anyway, and this concept has it built in without another layer of custom code.
Your resources exist until you delete them, which means you can view historical information long after the process and task complete.
You have built in service discovery, even for a task that has multiple steps, without any extra complicated protocols.
GET /task/name
- returns form with required fields
POST (URL provided form's "action" attribute)
Your service discovery is an HTML form - a universal and human readable format.
The entire flow can be used programmatically or by a human, using universally accepted tools. It's a client driven, and therefore RESTful. Every tool created for the web can drive your business processes. You still have alternate message channels by POSTing asynchronously to a separate array of log servers.
After you consider it for a while, you sit back and start to realize that REST may just eliminate the need for a messaging queue and an ESB altogether.

In Windows, even after installing graphviz-2.38.msi, you can add your own path in pydot.py (found under site-package folder)
if os.sys.platform == 'win32':
# Try and work out the equivalent of "C:\Program Files" on this
# machine (might be on drive D:, or in a different language)
#
if os.environ.has_key('PROGRAMFILES'):
# Note, we could also use the win32api to get this
# information, but win32api may not be installed.
path = os.path.join(os.environ['PROGRAMFILES'], 'ATT', 'GraphViz', 'bin')
else:
#Just in case, try the default...
path = r"C:\PYTHON27\GraphViz\bin" # add here.
I have removed it from my references.Then run this in Package Manager Console
Install-Package WebMatrix.Data
Finally add WebMatrix.WebData assembly to references,and rebuild project.It works for me.I hope it solves your problem too.
This article offers a detailed explanation for why the (b - a)/ABS(a) formula makes sense. It is counter-intuitive at first, but once you play with the underlying arithmetic, it starts to make sense. As you get used to it eventually, it changes the way you look at percentages.
I got this error while installing awscli
on Windows 10 in anaconda (python 3.7).
While troubleshooting, I went to the answer https://stackoverflow.com/a/49991357/6862405 and then to https://stackoverflow.com/a/54582701/6862405. Finally found that I need to install the libraries PyOpenSSL
, cryptography
, enum34
, idna
and ipaddress
. After installing these (using simply pip install
command), I was able to install awscli
.
If you want to clean up the whole form, you can use such approach. This is your model into controller:
$scope.registrationForm = {
'firstName' : '',
'lastName' : ''
};
Your HTML:
<form class="form-horizontal" name="registrForm" role="form">
<input type="text" class="form-control"
name="firstName"
id="firstName"
ng-model="registrationForm.firstName"
placeholder="First name"
required> First name
<input type="text" class="form-control"
name="lastName"
id="lastName"
ng-model="registrationForm.lastName"
placeholder="Last name"
required> Last name
</form>
Then, you should clone/save your clear state by:
$scope.originForm = angular.copy($scope.registrationForm);
Your reset function will be:
$scope.resetForm = function(){
$scope.registrationForm = angular.copy($scope.originForm); // Assign clear state to modified form
$scope.registrForm.$setPristine(); // this line will update status of your form, but will not clean your data, where `registrForm` - name of form.
};
In such way you are able to clean up the whole your form
You can also convert to datetime
without string concatenation, by combining datetime
and timedelta
objects. Combined with pd.DataFrame.pop
, you can remove the source series simultaneously:
df['DateTime'] = pd.to_datetime(df.pop('Date')) + pd.to_timedelta(df.pop('Time'))
print(df)

How to enable Developer Options:
Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.
In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.
This can also happend when the client needs to present a certificate. After the server lists the certificate chain, the following can happen:
3. Certificate Request The server will issue a certificate request from the client. The request will list all of the certificates the server accepts.
*** CertificateRequest
Cert Types: RSA
Cert Authorities:
<CN=blah, OU=blah, O=blah, L=blah, ST=blah, C=blah>
<CN=yadda, DC=yadda, DC=yadda>
<CN=moreblah, OU=moreblah, O=moreblah, C=moreblah>
<CN=moreyada, OU=moreyada, O=moreyada, C=moreyada>
... the rest of the request
*** ServerHelloDone
4. Client Certificate Chain This is the certificate the client is sending to the server.
*** Certificate chain
chain [0] = [
[
Version: V3
Subject: EMAILADDRESS=client's email, CN=client, OU=client's ou, O=client's Org, L=client's location, ST=client's state, C=client's Country
Signature Algorithm: SHA1withRSA, OID = 1.2.840.113549.1.1.5
... the rest of the certificate
*** ClientKeyExchange, RSA PreMasterSecret, TLSv1
... key exchange info
If there isn't a certificate in the chain and the server requires one, you'll get the handshake error here. A likely cause is the path to your certificate wasn't found.
5. Certificate Verify The client asks the server to verify the certificate
*** CertificateVerify
... payload of verify check
This step will only happen if you are sending a certificate.
6. Finished The server will respond with a verify response
*** Finished
verify_data: { 345, ... }
For enabling Offline mode Android Studio Version Above 3.6, refer the following answer.
Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code.
CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well.
If you have Windows developers used to Visual Studio and Unix developers who swear by GNU Make, CMake is (one of) the way(s) to go.
I would always recommend using CMake (or another buildsystem generator, but CMake is my personal preference) if you intend your project to be multi-platform or widely usable. CMake itself also provides some nice features like dependency detection, library interface management, or integration with CTest, CDash and CPack.
Using a buildsystem generator makes your project more future-proof. Even if you're GNU-Make-only now, what if you later decide to expand to other platforms (be it Windows or something embedded), or just want to use an IDE?
Install "vbox-ssl-cacertificate.crt" certificate from %userprofile%\\.virtualbox\
and then reboot. If you don't have .virtualbox
folder - launch "Oracle VM VirtualBox" once and this folder will appear.
I had this issue not only on my machine but on many hosts, and this certificate fixed the issue. I figured it out by chance, because nowhere said about this certificate -_-
This snippet of code helped me to fix browser caching problems:
$("#my_image").on('load', function() {
console.log("image loaded correctly");
}).each(function() {
if($(this).prop('complete')) $(this).load();
});
When the browser cache is disabled, only this code doesn't work:
$("#my_image").on('load', function() {
console.log("image loaded correctly");
})
to make it work you have to add:
.each(function() {
if($(this).prop('complete')) $(this).load();
});
If you are trying to reference a commit in another repo than the issue is in, you can prefix the commit short hash with reponame@
.
Suppose your commit is in the repo named dev
, and the GitLab issue is in the repo named test
. You can leave a comment on the issue and reference the commit by dev@e9c11f0a
(where e9c11f0a is the first 8 letters of the sha hash of the commit you want to link to) if that makes sense.
<?php
require_once ( 'username.php' );
if (isset($_POST['textfield'])) {
echo username();
return;
}
echo '
<form name="form1" method="post" action="">
<p>
<label>
<input type="text" name="textfield" id="textfield">
</label>
</p>
<p>
<label>
<input type="submit" name="button" id="button" value="Submit">
</label>
</p>
</form>';
?>
You need to run the function in the page the form is sent to.

There are two stages to processing Unicode text. The first is "how can I input it and output it without losing information". The second is "how do I treat text according to local language conventions".
tchrist's post covers both, but the second part is where 99% of the text in his post comes from. Most programs don't even handle I/O correctly, so it's important to understand that before you even begin to worry about normalization and collation.
This post aims to solve that first problem
When you read data into Perl, it doesn't care what encoding it is. It allocates some memory and stashes the bytes away there. If you say print $str
, it just blits those bytes out to your terminal, which is probably set to assume everything that is written to it is UTF-8, and your text shows up.
Marvelous.
Except, it's not. If you try to treat the data as text, you'll see that Something Bad is happening. You need go no further than length
to see that what Perl thinks about your string and what you think about your string disagree. Write a one-liner like: perl -E 'while(<>){ chomp; say length }'
and type in ????
and you get 12... not the correct answer, 4.
That's because Perl assumes your string is not text. You have to tell it that it's text before it will give you the right answer.
That's easy enough; the Encode module has the functions to do that. The generic entry point is Encode::decode
(or use Encode qw(decode)
, of course). That function takes some string from the outside world (what we'll call "octets", a fancy of way of saying "8-bit bytes"), and turns it into some text that Perl will understand. The first argument is a character encoding name, like "UTF-8" or "ASCII" or "EUC-JP". The second argument is the string. The return value is the Perl scalar containing the text.
(There is also Encode::decode_utf8
, which assumes UTF-8 for the encoding.)
If we rewrite our one-liner:
perl -MEncode=decode -E 'while(<>){ chomp; say length decode("UTF-8", $_) }'
We type in ???? and get "4" as the result. Success.
That, right there, is the solution to 99% of Unicode problems in Perl.
The key is, whenever any text comes into your program, you must decode it. The Internet cannot transmit characters. Files cannot store characters. There are no characters in your database. There are only octets, and you can't treat octets as characters in Perl. You must decode the encoded octets into Perl characters with the Encode module.
The other half of the problem is getting data out of your program. That's easy to; you just say use Encode qw(encode)
, decide what the encoding your data will be in (UTF-8 to terminals that understand UTF-8, UTF-16 for files on Windows, etc.), and then output the result of encode($encoding, $data)
instead of just outputting $data
.
This operation converts Perl's characters, which is what your program operates on, to octets that can be used by the outside world. It would be a lot easier if we could just send characters over the Internet or to our terminals, but we can't: octets only. So we have to convert characters to octets, otherwise the results are undefined.
To summarize: encode all outputs and decode all inputs.
Now we'll talk about three issues that make this a little challenging. The first is libraries. Do they handle text correctly? The answer is... they try. If you download a web page, LWP will give you your result back as text. If you call the right method on the result, that is (and that happens to be decoded_content
, not content
, which is just the octet stream that it got from the server.) Database drivers can be flaky; if you use DBD::SQLite with just Perl, it will work out, but if some other tool has put text stored as some encoding other than UTF-8 in your database... well... it's not going to be handled correctly until you write code to handle it correctly.
Outputting data is usually easier, but if you see "wide character in print", then you know you're messing up the encoding somewhere. That warning means "hey, you're trying to leak Perl characters to the outside world and that doesn't make any sense". Your program appears to work (because the other end usually handles the raw Perl characters correctly), but it is very broken and could stop working at any moment. Fix it with an explicit Encode::encode
!
The second problem is UTF-8 encoded source code. Unless you say use utf8
at the top of each file, Perl will not assume that your source code is UTF-8. This means that each time you say something like my $var = '??'
, you're injecting garbage into your program that will totally break everything horribly. You don't have to "use utf8", but if you don't, you must not use any non-ASCII characters in your program.
The third problem is how Perl handles The Past. A long time ago, there was no such thing as Unicode, and Perl assumed that everything was Latin-1 text or binary. So when data comes into your program and you start treating it as text, Perl treats each octet as a Latin-1 character. That's why, when we asked for the length of "????", we got 12. Perl assumed that we were operating on the Latin-1 string "æååã" (which is 12 characters, some of which are non-printing).
This is called an "implicit upgrade", and it's a perfectly reasonable thing to do, but it's not what you want if your text is not Latin-1. That's why it's critical to explicitly decode input: if you don't do it, Perl will, and it might do it wrong.
People run into trouble where half their data is a proper character string, and some is still binary. Perl will interpret the part that's still binary as though it's Latin-1 text and then combine it with the correct character data. This will make it look like handling your characters correctly broke your program, but in reality, you just haven't fixed it enough.
Here's an example: you have a program that reads a UTF-8-encoded text file, you tack on a Unicode PILE OF POO
to each line, and you print it out. You write it like:
while(<>){
chomp;
say "$_ ";
}
And then run on some UTF-8 encoded data, like:
perl poo.pl input-data.txt
It prints the UTF-8 data with a poo at the end of each line. Perfect, my program works!
But nope, you're just doing binary concatenation. You're reading octets from the file, removing a \n
with chomp, and then tacking on the bytes in the UTF-8 representation of the PILE OF POO
character. When you revise your program to decode the data from the file and encode the output, you'll notice that you get garbage ("ð©") instead of the poo. This will lead you to believe that decoding the input file is the wrong thing to do. It's not.
The problem is that the poo is being implicitly upgraded as latin-1. If you use utf8
to make the literal text instead of binary, then it will work again!
(That's the number one problem I see when helping people with Unicode. They did part right and that broke their program. That's what's sad about undefined results: you can have a working program for a long time, but when you start to repair it, it breaks. Don't worry; if you are adding encode/decode statements to your program and it breaks, it just means you have more work to do. Next time, when you design with Unicode in mind from the beginning, it will be much easier!)
That's really all you need to know about Perl and Unicode. If you tell Perl what your data is, it has the best Unicode support among all popular programming languages. If you assume it will magically know what sort of text you are feeding it, though, then you're going to trash your data irrevocably. Just because your program works today on your UTF-8 terminal doesn't mean it will work tomorrow on a UTF-16 encoded file. So make it safe now, and save yourself the headache of trashing your users' data!
The easy part of handling Unicode is encoding output and decoding input. The hard part is finding all your input and output, and determining which encoding it is. But that's why you get the big bucks :)
OK here is what worked for me! I have a button on my left Nav. If you click it it will open a window and that window will load a document. After loading the document I want print the document then close the popup window immediately.
contentDiv.focus();
contentDiv.contentWindow.print();
contentDiv.contentWindow.onfocus = function() {
window.close();
};
Why does this work?
Well, after printing you set the onfocus event to close the window. The print popup will load so quickly that the onfocus event will not get a chance to trigger until you 1)print 2) cancel the print. Once you regain focus on the window, the window will close!
I hope that will work for you
Here is an example:
Via css:
<style>
.my-table {
page-break-before: always;
page-break-after: always;
}
.my-table tr {
page-break-inside: avoid;
}
</style>
or directly on the element:
<table style="page-break-before: always; page-break-after: always;">
<tr style="page-break-inside: avoid;">
..
</tr>
</table>
Quick and dirty, and store it in a variable:
USER=somebody
USER_HOME="$(echo -n $(bash -c "cd ~${USER} && pwd"))"

I have different approach if you want access token and make call to other resource system with access token in header
Spring Security comes with automatic security: oauth2 properties access from application.yml file for every request and every request has SESSIONID which it reads and pull user info via Principal, so you need to make sure inject Principal in OAuthUser and get accessToken and make call to resource server
This is your application.yml, change according to your auth server:
security:
oauth2:
client:

Although this question is 5 years old I have come across a nice solution.
Use the 'DictionaryEntry' object to pair keys and values.
Set the 'DisplayMember' and 'ValueMember' properties to:
Me.myComboBox.DisplayMember = "Key"
Me.myComboBox.ValueMember = "Value"
To add items to the ComboBox:
Me.myComboBox.Items.Add(New DictionaryEntry("Text to be displayed", 1))
To retreive items like this:
MsgBox(Me.myComboBox.SelectedItem.Key & " " & Me.myComboBox.SelectedItem.Value)
Here is another way to accomplish this in less code.
UPDATE 3: Asynchronous model class statics
Similar to option 2, this allows you to create a function directly linked to the schema, but called from the same file using the model.
model.js
userSchema.statics.updateUser = function(user, cb) {
UserModel.find({name : user.name}).exec(function(err, docs) {
if (docs.length){
cb('Name exists already', null);
} else {
user.save(function(err) {
cb(err,user);
}
}
});
}
Call from file
var User = require('./path/to/model');
User.updateUser(user.name, function(err, user) {
if(err) {
var error = new Error('Already exists!');
error.status = 401;
return next(error);
}
});
If you are using wamp server , then i recommend you to use xampp server . you . i get this error in less than i minute but i resolved this by using (isset) function . and i get no error . and after that i remove (isset) function and i don,t see any error.
by the way i am using xampp server
A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.
If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

Yes if you are using latest java which is version 8. Java8 make it possible to define anonymous functions which was impossible in previous versions.
Lets take example from java docs to get know how we can declare anonymous functions, classes
The following example, HelloWorldAnonymousClasses, uses anonymous classes in the initialization statements of the local variables frenchGreeting and spanishGreeting, but uses a local class for the initialization of the variable englishGreeting:
public class HelloWorldAnonymousClasses {
interface HelloWorld {
public void greet();
public void greetSomeone(String someone);
}
public void sayHello() {
class EnglishGreeting implements HelloWorld {
String name = "world";
public void greet() {
greetSomeone("world");
}
public void greetSomeone(String someone) {
name = someone;
System.out.println("Hello " + name);
}
}
HelloWorld englishGreeting = new EnglishGreeting();
HelloWorld frenchGreeting = new HelloWorld() {
String name = "tout le monde";
public void greet() {
greetSomeone("tout le monde");
}
public void greetSomeone(String someone) {
name = someone;
System.out.println("Salut " + name);
}
};
HelloWorld spanishGreeting = new HelloWorld() {
String name = "mundo";
public void greet() {
greetSomeone("mundo");
}
public void greetSomeone(String someone) {
name = someone;
System.out.println("Hola, " + name);
}
};
englishGreeting.greet();
frenchGreeting.greetSomeone("Fred");
spanishGreeting.greet();
}
public static void main(String... args) {
HelloWorldAnonymousClasses myApp =
new HelloWorldAnonymousClasses();
myApp.sayHello();
}
}
Syntax of Anonymous Classes
Consider the instantiation of the frenchGreeting object:
HelloWorld frenchGreeting = new HelloWorld() {
String name = "tout le monde";
public void greet() {
greetSomeone("tout le monde");
}
public void greetSomeone(String someone) {
name = someone;
System.out.println("Salut " + name);
}
};
The anonymous class expression consists of the following:
new
operatorThe name of an interface to implement or a class to extend. In this example, the anonymous class is implementing the interface HelloWorld.
Parentheses that contain the arguments to a constructor, just like a normal class instance creation expression. Note: When you implement an interface, there is no constructor, so you use an empty pair of parentheses, as in this example.
A body, which is a class declaration body. More specifically, in the body, method declarations are allowed but statements are not.
If you wanna compare Spring MVC with struts consider below benefit of Spring MVC over Struts.
Try this -
EditText myEditText = (EditText) findViewById(R.id.vnosEmaila);
String text = myEditText.getText().toString();
For MySQL Workbench 6.1: in the home window click on the server instance(connection)/ or create a new one. In the thus opened 'connection' tab click on 'server' -> 'data import'. The rest of the steps remain as in Vishy's answer.
parse_cols
is deprecated, use usecols
instead
that is:
df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")
Please show us more parts of the script and tell us what commands you had to individually execute and want to simply.
Meanwhile you have to use double quotes not single quote to expand variables:
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
Semicolons at the end of a single command are also unnecessary.
So far:
#!/bin/sh
echo "Perform Operation in su mode"
export ARCH=arm
echo "Export ARCH=arm Executed"
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
echo "Export path done"
export CROSS_COMPILE='/home/linux/Practise/linux-devkit/bin/arm-arago-linux-gnueabi-' ## What's next to -?
echo "Export CROSS_COMPILE done"
# continue your compilation commands here
...
For su
you can run it with:
su -c 'sh /path/to/script.sh'
Note: The OP was not explicitly asking for steps on how to create export variables in an interactive shell using a shell script. He only asked his script to be assessed at most. He didn't mention details on how his script would be used. It could have been by using .
or source
from the interactive shell. It could have been a standalone scipt, or it could have been source
'd from another script. Environment variables are not specific to interactive shells. This answer solved his problem.
for ( i = 0; i < total.length; i++ ); // remove this
{
if (total[i]!=0)
System.out.println( "Letter" + (char)( 'a' + i) + " count =" + total[i]);
}
The for loop loops until i=26
(where 26 is total.length
) and then your if
is executed, going over the bounds of the array. Remove the ;
at the end of the for
loop.
All the above answers are good, my aim is to explain the concept in a simple way so that anyone without a programming knowledge can also understand concept
Dependency injection is one of the design pattern that help us to create complex systems in a simpler manner.
We can see a wide variety of application of this pattern in our day to day life. Some of the examples are Tape recorder, VCD, CD Drive etc.
The above image is an image of Reel-to-reel portable tape recorder, mid-20th century. Source.
The primary intention of a tape recorder machine is to record or playback sound.
While designing a system it require a reel to record or playback sound or music. There are two possibilities for designing this system
If we use the first one we need to open the machine to change the reel. if we opt for the second one, that is placing a hook for reel, we are getting an added benefit of playing any music by changing the reel. and also reducing the function only to playing whatever in the reel.
Like wise dependency injection is the process of externalizing the dependencies to focus only on the specific functionality of the component so that independent components can be coupled together to form a complex system.
The main benefits we achieved by using dependency injection.
Now a days these concept forms the basis of well known frameworks in programming world. The Spring Angular etc are the well-known software frameworks built on the top of this concept
Dependency injection is a pattern used to create instances of objects that other objects rely upon without knowing at compile time which class will be used to provide that functionality or simply the way of injecting properties to an object is called dependency injection.
Example for Dependency injection
Previously we are writing code like this
Public MyClass{
DependentClass dependentObject
/*
At somewhere in our code we need to instantiate
the object with new operator inorder to use it or perform some method.
*/
dependentObject= new DependentClass();
dependentObject.someMethod();
}
With Dependency injection, the dependency injector will take off the instantiation for us
Public MyClass{
/* Dependency injector will instantiate object*/
DependentClass dependentObject
/*
At somewhere in our code we perform some method.
The process of instantiation will be handled by the dependency injector
*/
dependentObject.someMethod();
}

$location won't help you with external URLs, use the $window service instead:
$window.location.href = 'http://www.google.com';
Note that you could use the window object, but it is bad practice since $window is easily mockable whereas window is not.
I think there is an unwritten rule (something like a convention) that says to use 'alias' just for registering a method-name alias, means if you like to give the user of your code one method with more than one name:
class Engine
def start
#code goes here
end
alias run start
end
If you need to extend your code, use the ruby meta alternative.
class Engine
def start
puts "start me"
end
end
Engine.new.start() # => start me
Engine.class_eval do
unless method_defined?(:run)
alias_method :run, :start
define_method(:start) do
puts "'before' extension"
run()
puts "'after' extension"
end
end
end
Engine.new.start
# => 'before' extension
# => start me
# => 'after' extension
Engine.new.run # => start me
you have to tell git where to pull from, in this case from the current directory/repository:
git pull . master
but when working locally, you usually just call merge (pull internally calls merge):
git merge master
Since many browsers block popups by default and popups are really ugly, I recommend using lightbox or thickbox.
They are prettier and are not popups. They are extra HTML markups that are appended to your document's body with the appropriate CSS content.
OS_ACTIVITY_MODE = disable
This will also disable the ability to debug in real devices (no console output from real devices from then on).
This is a crazy thing of apple. When you say self.navigationItem.rightBarButtonItem.title then it will say nil while on the GUI it shows Edit or Save. Fresher likes me will take a lot of time to debug this behavior.
There is a requirement that the Item will show Edit in the firt load then user taps on it It will change to Save title. To archive this, i did as below.
//view did load will say Edit title
private func loadRightBarItem() {
let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
self.navigationItem.rightBarButtonItem = logoutBarButtonItem
}
// tap Edit item will change to Save title
@objc private func handleEditBtn() {
print("clicked on Edit btn")
let logoutBarButtonItem = UIBarButtonItem(title: "Save", style: .done, target: self, action: #selector(handleSaveBtn))
self.navigationItem.rightBarButtonItem = logoutBarButtonItem
blockEditTable(isBlock: false)
}
//tap Save item will display Edit title
@objc private func handleSaveBtn(){
print("clicked on Save btn")
let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
self.navigationItem.rightBarButtonItem = logoutBarButtonItem
saveInvitation()
blockEditTable(isBlock: true)
}
As rightly said by previous posts, one of way is to implement a custom basic authentication middleware. I found the best working code with explanation in this blog: Basic Auth with custom middleware
I referred the same blog but had to do 2 adaptations:
While reading the username, password from appsettings.json file, add static read only property in Startup file. Then read from appsettings.json. Finally, read the values from anywhere in the project. Example:
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public static string UserNameFromAppSettings { get; private set; }
public static string PasswordFromAppSettings { get; private set; }
//set username and password from appsettings.json
UserNameFromAppSettings = Configuration.GetSection("BasicAuth").GetSection("UserName").Value;
PasswordFromAppSettings = Configuration.GetSection("BasicAuth").GetSection("Password").Value;
}
The differences are listed in the Javadoc for ListIterator
You can
if the possible values are integers you can bunch up cases. Otherwise, use ifs.
var api, tem;
switch(liCount){
case 0:
tem= 'start';
break;
case 1: case 2: case 3: case 4: case 5:
tem= 'upload1Row';
break;
case 6: case 7: case 8: case 9: case 10:
tem= 'upload2Rows';
break;
default:
break;
}
if(tem) setLayoutState((tem);
api= $('#UploadList').data('jsp');
api.reinitialise();
For Ubuntu users, an answer can be found here. I also quote it:
The most probable cause, is that you have not installed the appropriate dependencies. Your Ubuntu system has to have some packages installed regarding conversion of LaTeX and XeTeX files, in order to save your notebook as PDF. You can install them by:
sudo apt-get install texlive texlive-xetex texlive-generic-extra texlive-generic-recommended pandoc
Also,
nbconvert
is another dependency that is usually automatically installed with jupyter. But you can install it just to be sure, while having your virtual environment activated:pip install -U nbconvert
It's very easy to write that yourself, and that way you have more control over things.. As the other answers say, TypeScript is not aimed at adding runtime types or functionality.
Map:
class Map<T> {
private items: { [key: string]: T };
constructor() {
this.items = {};
}
add(key: string, value: T): void {
this.items[key] = value;
}
has(key: string): boolean {
return key in this.items;
}
get(key: string): T {
return this.items[key];
}
}
List:
class List<T> {
private items: Array<T>;
constructor() {
this.items = [];
}
size(): number {
return this.items.length;
}
add(value: T): void {
this.items.push(value);
}
get(index: number): T {
return this.items[index];
}
}
I haven't tested (or even tried to compile) this code, but it should give you a starting point.. you can of course then change what ever you want and add the functionality that YOU need...
As for your "special needs" from the List, I see no reason why to implement a linked list, since the javascript array lets you add and remove items.
Here's a modified version of the List to handle the get prev/next from the element itself:
class ListItem<T> {
private list: List<T>;
private index: number;
public value: T;
constructor(list: List<T>, value: T, index: number) {
this.list = list;
this.index = index;
this.value = value;
}
prev(): ListItem<T> {
return this.list.get(this.index - 1);
}
next(): ListItem<T> {
return this.list.get(this.index + 1);
}
}
class List<T> {
private items: Array<ListItem<T>>;
constructor() {
this.items = [];
}
size(): number {
return this.items.length;
}
add(value: T): void {
this.items.push(new ListItem<T>(this, value, this.size()));
}
get(index: number): ListItem<T> {
return this.items[index];
}
}
Here too you're looking at untested code..
Hope this helps.
Javascript has a native Map object so there's no need to create your own:
let map = new Map();
map.set("key1", "value1");
console.log(map.get("key1")); // value1
Usually the problem is not closing brackets (}) or missing semicolon (;)
you can use this command to git single branch and rename the folder if you want to keep branched stand alone
git clone -b [branch-name] --single-branch [url] [folder_name]
example
git clone -b mybranch --single-branch git://github/repository.git project_mybranch
You can use itertools.tee
and zip
to efficiently build the result:
from itertools import tee
# python2 only:
#from itertools import izip as zip
def differences(seq):
iterable, copied = tee(seq)
next(copied)
for x, y in zip(iterable, copied):
yield y - x
Or using itertools.islice
instead:
from itertools import islice
def differences(seq):
nexts = islice(seq, 1, None)
for x, y in zip(seq, nexts):
yield y - x
You can also avoid using the itertools
module:
def differences(seq):
iterable = iter(seq)
prev = next(iterable)
for element in iterable:
yield element - prev
prev = element
All these solution work in constant space if you don't need to store all the results and support infinite iterables.
Here are some micro-benchmarks of the solutions:
In [12]: L = range(10**6)
In [13]: from collections import deque
In [15]: %timeit deque(differences_tee(L), maxlen=0)
10 loops, best of 3: 122 ms per loop
In [16]: %timeit deque(differences_islice(L), maxlen=0)
10 loops, best of 3: 127 ms per loop
In [17]: %timeit deque(differences_no_it(L), maxlen=0)
10 loops, best of 3: 89.9 ms per loop
And the other proposed solutions:
In [18]: %timeit [x[1] - x[0] for x in zip(L[1:], L)]
10 loops, best of 3: 163 ms per loop
In [19]: %timeit [L[i+1]-L[i] for i in range(len(L)-1)]
1 loops, best of 3: 395 ms per loop
In [20]: import numpy as np
In [21]: %timeit np.diff(L)
1 loops, best of 3: 479 ms per loop
In [35]: %%timeit
...: res = []
...: for i in range(len(L) - 1):
...: res.append(L[i+1] - L[i])
...:
1 loops, best of 3: 234 ms per loop
Note that:
zip(L[1:], L)
is equivalent to zip(L[1:], L[:-1])
since zip
already terminates on the shortest input, however it avoids a whole copy of L
.numpy.diff
is slow because it has to first convert the list
to a ndarray
. Obviously if you start with an ndarray
it will be much faster:
In [22]: arr = np.array(L)
In [23]: %timeit np.diff(arr)
100 loops, best of 3: 3.02 ms per loop
In Python 3, urllib.quote
has been moved to urllib.parse.quote
and it does handle unicode by default.
>>> from urllib.parse import quote
>>> quote('/test')
'/test'
>>> quote('/test', safe='')
'%2Ftest'
>>> quote('/El Niño/')
'/El%20Ni%C3%B1o/'
This is the best way for me:
cat filename.tsv |
while read FILENAME
do
sudo find /PATH_FROM/ -name "$FILENAME" -maxdepth 4 -exec cp '{}' /PATH_TO/ \; ;
done
use jQuery's $.getJSON
$.getJSON('mydata.json', function(data) {
//do stuff with your data here
});
Use window.getSelection().toString()
.

pattern="foo"
for _dir in *"${pattern}"*; do
[ -d "${_dir}" ] && dir="${_dir}" && break
done
echo "${dir}"
This is better than the other shell solution provided because
${dir}
will be empty)=~
operator (if you need this depends on your pattern)find
)As of Ruby 2.5 you can use delete_suffix
or delete_suffix!
to achieve this in a fast and readable manner.
The docs on the methods are here.
If you know what the suffix is, this is idiomatic (and I'd argue, even more readable than other answers here):
'abc123'.delete_suffix('123') # => "abc"
'abc123'.delete_suffix!('123') # => "abc"
It's even significantly faster (almost 40% with the bang method) than the top answer. Here's the result of the same benchmark:
user system total real
chomp 0.949823 0.001025 0.950848 ( 0.951941)
range 1.874237 0.001472 1.875709 ( 1.876820)
delete_suffix 0.721699 0.000945 0.722644 ( 0.723410)
delete_suffix! 0.650042 0.000714 0.650756 ( 0.651332)
I hope this is useful - note the method doesn't currently accept a regex so if you don't know the suffix it's not viable for the time being. However, as the accepted answer (update: at the time of writing) dictates the same, I thought this might be useful to some people.
Based on github issue #620, it looks like you'll soon be able to do the following:
df[df['A'].str.contains("hello")]
Update: vectorized string methods (i.e., Series.str) are available in pandas 0.8.1 and up.
The answer for git branch -r --contains <commit>
works well for normal remote branches, but if the commit is only in the hidden head
namespace that GitHub creates for PRs, you'll need a few more steps.
Say, if PR #42 was from deleted branch and that PR thread has the only reference to the commit on the repo, git branch -r
doesn't know about PR #42 because refs like refs/pull/42/head
aren't listed as a remote branch by default.
In .git/config
for the [remote "origin"]
section add a new line:
fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
(This gist has more context.)
Then when you git fetch
you'll get all the PR branches, and when you run git branch -r --contains <commit>
you'll see origin/pr/42
contains the commit.
If you wish to log all output to a file AND output it to a text file then you can do the following. It's a bit hacky but it works:
import logging
debug = input("Debug or not")
if debug == "1":
logging.basicConfig(level=logging.DEBUG, filename='./OUT.txt')
old_print = print
def print(string):
old_print(string)
logging.info(string)
print("OMG it works!")
import logging, sys
debug = input("Debug or not")
if debug == "1":
old_input = input
sys.stderr.write = logging.info
def input(string=""):
string_in = old_input(string)
logging.info("STRING IN " + string_in)
return string_in
logging.basicConfig(level=logging.DEBUG, filename='./OUT.txt')
old_print = print
def print(string="", string2=""):
old_print(string, string2)
logging.info(string)
logging.info(string2)
print("OMG")
b = input()
print(a) ## Deliberate error for testing
I faced the same problem,but after hours of efforts i find the solution.It can be without using any external plugin:)
applicantListToExport: function (query, callback) {
this
.find(query).select({'advtId': 0})
.populate({
path: 'influId',
model: 'influencer',
select: { '_id': 1,'user':1},
populate: {
path: 'userid',
model: 'User'
}
})
.populate('campaignId',{'campaignTitle':1})
.exec(callback);
}
itemgetter
(see other answers) is (as I know) more efficient for large dictionaries but for the common case, I believe that d.get
wins. And it does not require an extra import
.
>>> d = {"aa": 3, "bb": 4, "cc": 2, "dd": 1}
>>> for k in sorted(d, key=d.get, reverse=True):
... k, d[k]
...
('bb', 4)
('aa', 3)
('cc', 2)
('dd', 1)
Note that alternatively you can set d.__getitem__
as key
function which may provide a small performance boost over d.get
.
Additionally, please note a.update( b )
is 2x faster than a + b
from collections import Counter
a = Counter({'menu': 20, 'good': 15, 'happy': 10, 'bar': 5})
b = Counter({'menu': 1, 'good': 1, 'bar': 3})
%timeit a + b;
## 100000 loops, best of 3: 8.62 µs per loop
## The slowest run took 4.04 times longer than the fastest. This could mean that an intermediate result is being cached.
%timeit a.update(b)

There are actually cases in numerical software where you want to check whether two floating point numbers are exactly equal. I posted this on a similar question
https://stackoverflow.com/a/10973098/1447411
So you can not say that "CompareDoubles1" is wrong in general.
X-XSS-Protection is a HTTP header understood by Internet Explorer 8 (and newer versions). This header lets domains toggle on and off the "XSS Filter" of IE8, which prevents some categories of XSS attacks. IE8 has the filter activated by default, but servers can switch if off by setting
X-XSS-Protection: 0
The error usually gets introduced while creation of CSV. Try using Linux for saving the CSV as a TextCSV. Libre Office in Ubuntu can enforce the encoding to be UTF-8, worked for me. I wasted a lot of time trying this on Mac OS. Linux is the key. I've tested on Ubuntu.
Good Luck
You need to open up your SDK Manager and make sure everything is installed, especially System Image. After that will be alright!
What do you mean by impacts? Content will flow around a float. That's how they work.
If you want it to appear above your design, try setting:

top: 0;
late to the party, was searching for same, as "in" is not valid, I had just created following.
def find_str(full, sub):

sub_index = 0
position = -1
for ch_i,ch_f in enumerate(full) :
if ch_f.lower() != sub[sub_index].lower():
position = -1
sub_index = 0
if ch_f.lower() == sub[sub_index].lower():
if sub_index == 0 :
position = ch_i
if (len(sub) - 1) <= sub_index :
break
else:
sub_index += 1
return position
print(find_str("Happy birthday", "py"))
print(find_str("Happy birthday", "rth"))
print(find_str("Happy birthday", "rh"))
which produces

I played around with nico's answer a little and it felt jumpy. Did a bit of investigation and found window.requestAnimationFrame
which is a function that is called on each repaint cycle. This allows for a more clean-looking animation. Still trying to hone in on good default values for step size but for my example things look pretty good using this implementation.

scrollContainer = scrollContainer.parentNode;
if (!scrollContainer) return;
scrollContainer.scrollTop += 1;

The <p>
paragraph tag is meant for specifying paragraphs of text. If you don't want the text to start on a new line, I would suggest you're using the <p>
tag incorrectly. Perhaps the <span>
tag more closely fits what you want to achieve...?
To link to a YouTube video so it plays in HD by default, use the following URL:
https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080
Change VIDEOID to the YouTube video ID that you want to link to. When someone follows the link, it will display the highest-resolution available (up to 1080p) in full-screen mode. Unfortunately, vq=hd1080 does not work on the normal YouTube site (with comments and related videos).
var jPlayPause = $("#play-pause");
jPlayPause.text(jPlayPause.hasClass("playing") ? "play" : "pause");
jPlayPause.toggleClass("playing");
This is a piece of thought using jQuery's toggleClass() method.
Suppose you have an element with id="play-pause" and you want to toggle the text between "play" and "pause".
If you can give up the scales/axis labels, you can rescale the data to (0, 1) interval. This works for example for different 'wiggle' trakcs on chromosomes, when you're generally interested in local correlations between the tracks and they have different scales (coverage in thousands, Fst 0-1).
# rescale numeric vector into (0, 1) interval
# clip everything outside the range
rescale <- function(vec, lims=range(vec), clip=c(0, 1)) {
# find the coeficients of transforming linear equation
# that maps the lims range to (0, 1)
slope <- (1 - 0) / (lims[2] - lims[1])
intercept <- - slope * lims[1]
xformed <- slope * vec + intercept
# do the clipping
xformed[xformed < 0] <- clip[1]
xformed[xformed > 1] <- clip[2]
xformed
}
Then, having a data frame with chrom
, position
, coverage
and fst
columns, you can do something like:
ggplot(d, aes(position)) +
geom_line(aes(y = rescale(fst))) +
geom_line(aes(y = rescale(coverage))) +
facet_wrap(~chrom)
The advantage of this is that you're not limited to two trakcs.
use ProgressDialog.
ProgressDialog dialog=new ProgressDialog(context);
dialog.setMessage("message");
dialog.setCancelable(false);
dialog.setInverseBackgroundForced(false);
dialog.show();
hide it whenever your UI is ready with data. call :
dialog.hide();
Here T refers to a Class.It can be a reference type.
try below code
Directory.GetFiles(txtFolderPath.Text, "*ProfileHandler.cs",SearchOption.AllDirectories)
Runas.exe won't work here. You can use VBScript to invoke the "Run as Administrator" shell verb. The Elevation Powertoys contain a batchfile that allows you to invoke an elevated command:

Simply restarting Visual Studio worked for me.
With Regular Expressions, how to get numbers from a String, for example:
String myString = "my 2 first gifts were made by my 4 brothers";
myString = myString .replaceAll("\\D+","");
System.out.println("myString : " + myString);
the result of myString
is "24
"
you can see an example of this running code here: http://ideone.com/iOCf5G

The CLR uses it when it is compiling at runtime. Here is a link to MSDN that explains further.
Another approach if you wanted to swap out a specific character for another character:
def swap(input_string):
if len(input_string) == 0:
return input_string
if input_string[0] == "x":
return "y" + swap(input_string[1:])
else:
return input_string[0] + swap(input_string[1:])
For reading/writing excel files, you can use :
readxl
package for reading and writexl
package for writingopenxlsx
package for reading and writingWith xlsx
and XLConnect
(which use rjava) you will face memory errors if you have large files
One often-overlooked advantage of calloc
is that (conformant implementations of) it will help protect you against integer overflow vulnerabilities. Compare:
size_t count = get_int32(file);
struct foo *bar = malloc(count * sizeof *bar);
vs.
size_t count = get_int32(file);
struct foo *bar = calloc(count, sizeof *bar);
The former could result in a tiny allocation and subsequent buffer overflows, if count
is greater than SIZE_MAX/sizeof *bar
. The latter will automatically fail in this case since an object that large cannot be created.
Of course you may have to be on the lookout for non-conformant implementations which simply ignore the possibility of overflow... If this is a concern on platforms you target, you'll have to do a manual test for overflow anyway.
Subsetting the data and combining them back is unnecessary. So are loops since those operations are vectorized. From your previous edit, I'm guessing you are doing all of this to make bubble plots. If that is correct, perhaps the example below will help you. If this is way off, I can just delete the answer.
library(ggplot2)
# let's look at the included dataset named trees.
# ?trees for a description
data(trees)
ggplot(trees,aes(Height,Volume)) + geom_point(aes(size=Girth))
# Great, now how do we color the bubbles by groups?
# For this example, I'll divide Volume into three groups: lo, med, high
trees$set[trees$Volume<=22.7]="lo"
trees$set[trees$Volume>22.7 & trees$Volume<=45.4]="med"
trees$set[trees$Volume>45.4]="high"
ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth))
# Instead of just circles scaled by Girth, let's also change the symbol
ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth,pch=set))
# Now let's choose a specific symbol for each set. Full list of symbols at ?pch
trees$symbol[trees$Volume<=22.7]=1
trees$symbol[trees$Volume>22.7 & trees$Volume<=45.4]=2
trees$symbol[trees$Volume>45.4]=3
ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth,pch=symbol))
This is not possible from HTML on. The closest what you can get is the accept-charset
attribute of the <form>
. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type
header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.
To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding
attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).
Update:
Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type
header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.
SELECT IDENT_CURRENT('Table')
You can use one of these examples:
SELECT * FROM Table
WHERE ID = (
SELECT IDENT_CURRENT('Table'))
SELECT * FROM Table
WHERE ID = (
SELECT MAX(ID) FROM Table)
SELECT TOP 1 * FROM Table
ORDER BY ID DESC
But the first one will be more efficient because no index scan is needed (if you have index on Id column).
The second one solution is equivalent to the third (both of them need to scan table to get max id).
I found the easiest way is using str(timedelta)
. It will return a sting formatted like 3 days, 21:06:40.001000
, and you can parse hours and minutes using simple string operations or regular expression.
create two Date
objects and call valueOf()
on both, then compare them.
You need to multi value check. Try using the following code :
<?php
$illstack=array(...............);
$val=array('uk','bn','in');
if(count(array_intersect($illstack,$val))===count($val)){ // all of $val is in $illstack}
?>
If you are converting DataFrame to JSON, NaN
will give error so best solution is in this use case is to replace NaN
with None
.
Here is how:
df1 = df.where((pd.notnull(df)), None)
The Symfony documentation now explicitly shows how to do this:
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
'SELECT p

WHERE p.price > :price
ORDER BY p.price ASC'
)->setParameter('price', '19.99');
$products = $query->getResult();

I would like to share my way, first of all i had Huawei ascend p7 and my touch screen stopped handling touch, so none of the above solutions helped me to be unlock the phone, i have found a better clever way to do it since i can see the screen on thus i thought that my display is 1080 x 1920 px thus i had to simulate a drawing on my photoshop with keypad with (x,y) so i can try instead with input mouse tap
command.
Since i have pin lock as you can see in the picture, i have got all the (x,y) for all the numbers on the screen to simulate touch and unlock my screen and have to backup my data, thus if my password is 123 i did all the following commands
adb shell input mouse tap 100 1150
adb shell input mouse tap 500 1150
adb shell input mouse tap 900 1150
And then my phone just got unlocked, i hope it was helpful.

In my case, I needed to return the enum from a WCF service. I also needed a friendly name, not just the enum.ToString().
Here's my WCF Class.
[DataContract]
public class EnumMember
{
[DataMember]
public string Description { get; set; }
[DataMember]
public int Value { get; set; }
public static List<EnumMember> ConvertToList<T>()
{
Type type = typeof(T);
if (!type.IsEnum)
{
throw new ArgumentException("T must be of type enumeration.");
}
var members = new List<EnumMember>();
foreach (string item in System.Enum.GetNames(type))
{
var enumType = System.Enum.Parse(type, item);
members.Add(
new EnumMember() { Description = enumType.GetDescriptionValue(), Value = ((IConvertible)enumType).ToInt32(null) });
}
return members;
}
}
Here's the Extension method that gets the Description from the Enum.
public static string GetDescriptionValue<T>(this T source)
{
FieldInfo fileInfo = source.GetType().GetField(source.ToString());
DescriptionAttribute[] attributes = (DescriptionAttribute[])fileInfo.GetCustomAttributes(typeof(DescriptionAttribute), false);
if (attributes != null && attributes.Length > 0)
{
return attributes[0].Description;
}
else
{
return source.ToString();
}
}
Implementation:
return EnumMember.ConvertToList<YourType>();
The fact that you're using a view model has no bearing. The standard way of using PagedList
is to store "one page of items" as a ViewBag
variable. All you have to determine is what collection constitutes what you'll be paging over. You can't logically page multiple collections at the same time, so assuming you chose Instructors
:
ViewBag.OnePageOfItems = myViewModelInstance.Instructors.ToPagedList(pageNumber, 10);
Then, the rest of the standard code works as it always has.
If I remember correctly from my own use of bootstrap, the .spanN
classes are floated, which automatically makes them behave as display: block
. To make display: table-cell
work, you need to remove the float.
Please rather try:
$JAVA_HOME/bin/java -version
Maven uses $JAVA_HOME
for classpath resolution of JRE libs.
To be sure to use a certain JDK, set it explicitly before compiling, for example:
export JAVA_HOME=/usr/java/jdk1.7.0_51
Isn't there a version < 1.7 and you're using Maven 3.3.1? In this case the reason is a new prerequisite: https://issues.apache.org/jira/browse/MNG-5780
We can use buttonStyle
prop now.
https://react-native-training.github.io/react-native-elements/docs/button.html#buttonstyle
You just need to specify text-decoration: underline;
with pseudo-class :hover
.
<span class="underline-on-hover">Hello world</span>
.underline-on-hover:hover {
text-decoration: underline;
}
I have whipped up a working Code Pen Demo.
On Linux I would suggest,
# FILE_TO_BE_ATTACHED=abc.gz
uuencode abc.gz abc.gz > abc.gz.enc # This is optional, but good to have
# to prevent binary file corruption.
# also it make sure to get original
# file on other system, w/o worry of endianness
# Sending Mail, multiple attachments, and multiple receivers.
echo "Body Part of Mail" | mailx -s "Subject Line" -a attachment1 -a abc.gz.enc "[email protected] [email protected]"
Upon receiving mail attachment, if you have used uuencode, you would need uudecode
uudecode abc.gz.enc
# This will generate file as original with name as same as the 2nd argument for uuencode.

You can use the Web Services using an API_KEY issuing a request like this:
https://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&key=API_KEY
An API_KEY can be obtained in the Google Developer Console with a quota of 2,500 free requests/day.
A request can return JSON or XML results that can be used to draw a path on a map.
Official documentation for Web Services using the Google Maps Directions API are here
You can write your query like so:
SELECT * FROM MyTable WHERE (A LIKE '%text1%' OR A LIKE '%text2%')
The %
is a wildcard, meaning that it searches for all rows where column A contains either text1 or text2
The current Entity Framework EDM generator will create a composite key from all non-nullable fields in your view. In order to gain control over this, you will need to modify the view and underlying table columns setting the columns to nullable when you do not want them to be part of the primary key. The opposite is also true, as I encountered, the EDM generated key was causing data-duplication issues, so I had to define a nullable column as non-nullable to force the composite key in the EDM to include that column.
One possible way is to do something like this:
public class MyThread extends Thread {
@Override
public void run() {
while (!this.isInterrupted()) {
//
}
}
}
And when you want to stop your thread, just call a method interrupt():
myThread.interrupt();
Of course, this won't stop thread immediately, but in the following iteration of the loop above. In the case of downloading, you need to write a non-blocking code. It means, that you will attempt to read new data from the socket only for a limited amount of time. If there are no data available, it will just continue. It may be done using this method from the class Socket:
mySocket.setSoTimeout(50);
In this case, timeout is set up to 50 ms. After this time has gone and no data was read, it throws an SocketTimeoutException. This way, you may write iterative and non-blocking thread, which may be killed using the construction above.
It's not possible to kill thread in any other way and you've to implement such a behavior yourself. In past, Thread had some method (not sure if kill() or stop()) for this, but it's deprecated now. My experience is, that some implementations of JVM doesn't even contain that method currently.
Gradle can be added on the Mac by adding the line below to ~/.bash_profile
. If the file doesn't exist, please use touch ~/.bash_profile
. This hidden file can be made visible in Finder by using Command + Shift + .
export PATH=${PATH}:/Applications/Android\ Studio.app/Contents/gradle/gradle-4.6/bin/
Use source ~/.bash_profile
to load the new path directly into your current terminal session.
Check what $TERM gives: mine is xterm-color and ls -alG then does colorised output.
In Capybara you can use only find with xpath
find(:xpath, "//*[@id='organizationSelect']/option[2]").click
and method click
RichTextBox will allow you to use html to specify the color. Another alternative is using a listbox and using the DrawItem event to draw how you would like. AFAIK, textbox itself can't be used in the way you're hoping.
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
formatter.setLenient(false);
try {
Date date= formatter.parse("02/03/2010");
} catch (ParseException e) {
//If input date is in different format or invalid.
}
formatter.setLenient(false) will enforce strict matching.
If you are using Joda-Time -
private boolean isValidDate(String dateOfBirth) {
boolean valid = true;
try {
DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy");
DateTime dob = formatter.parseDateTime(dateOfBirth);
} catch (Exception e) {
valid = false;
}
return valid;
}
I think it's best to break the answer in depth and in simple words:
__name__
: Every module in Python has a special attribute called __name__
.
It is a built-in variable that returns the name of the module.
__main__
: Like other programming languages, Python too has an execution entry point, i.e., main. '__main__'
is the name of the scope in which top-level code executes. Basically you have two ways of using a Python module: Run it directly as a script, or import it. When a module is run as a script, its __name__
is set to __main__
.
Thus, the value of the __name__
attribute is set to __main__
when the module is run as the main program. Otherwise the value of __name__
is set to contain the name of the module.
Here is one good article to illustrate the difference among bind()
, apply()
and call()
, summarize it as below.
bind()
allows us to easily set which specific object will be bound to this when a function or method is invoked.
// This data variable is a global variable?
var data = [
{name:"Samantha", age:12},
{name:"Alexis", age:14}
]
var user = {
// local data variable?
data :[
{name:"T. Woods", age:37},
{name:"P. Mickelson", age:43}
],
showData:function (event) {
var randomNum = ((Math.random () * 2 | 0) + 1) - 1; // random number between 0 and 1?
console.log (this.data[randomNum].name + " " + this.data[randomNum].age);
}
}
// Assign the showData method of the user object to a variable?
var showDataVar = user.showData;
showDataVar (); // Samantha 12 (from the global data array, not from the local data array)?
/*
This happens because showDataVar () is executed as a global function and use of this inside
showDataVar () is bound to the global scope, which is the window object in browsers.
*/
// Bind the showData method to the user object?
var showDataVar = user.showData.bind (user);
// Now the we get the value from the user object because the this keyword is bound to the user object?
showDataVar (); // P. Mickelson 43?
bind()
allow us to borrow methods
// Here we have a cars object that does not have a method to print its data to the console?
var cars = {
data:[
{name:"Honda Accord", age:14},
{name:"Tesla Model S", age:2}
]
}
// We can borrow the showData () method from the user object we defined in the last example.?
// Here we bind the user.showData method to the cars object we just created.?
cars.showData = user.showData.bind (cars);
cars.showData (); // Honda Accord 14?
One problem with this example is that we are adding a new method showData
on the cars
object and
we might not want to do that just to borrow a method because the cars object might already have a property or method name showData
.
We don’t want to overwrite it accidentally. As we will see in our discussion of Apply
and Call
below,
it is best to borrow a method using either the Apply
or Call
method.
bind()
allow us to curry a function
Function Currying, also known as partial function application, is the use of a function (that accept one or more arguments) that returns a new function with some of the arguments already set.
function greet (gender, age, name) {
// if a male, use Mr., else use Ms.?
var salutation = gender === "male" ? "Mr. " : "Ms. ";
if (age > 25) {
return "Hello, " + salutation + name + ".";
}else {
return "Hey, " + name + ".";
}
}
We can use bind()
to curry this greet
function
// So we are passing null because we are not using the "this" keyword in our greet function.
var greetAnAdultMale = greet.bind (null, "male", 45);
greetAnAdultMale ("John Hartlove"); // "Hello, Mr. John Hartlove."
var greetAYoungster = greet.bind (null, "", 16);
greetAYoungster ("Alex"); // "Hey, Alex."?
greetAYoungster ("Emma Waterloo"); // "Hey, Emma Waterloo."
apply()
or call()
to set this value
The apply
, call
, and bind
methods are all used to set the this value when invoking a method, and they do it in slightly
different ways to allow use direct control and versatility in our JavaScript code.
The apply
and call
methods are almost identical when setting the this value except that you pass the function parameters to apply ()
as an array, while you have to list the parameters individually to pass them to the call ()
method.
Here is one example to use call
or apply
to set this in the callback function.
// Define an object with some properties and a method?
// We will later pass the method as a callback function to another function?
var clientData = {
id: 094545,
fullName: "Not Set",
// setUserName is a method on the clientData object?
setUserName: function (firstName, lastName) {
// this refers to the fullName property in this object?
this.fullName = firstName + " " + lastName;
}
};
function getUserInput (firstName, lastName, callback, callbackObj) {
// The use of the Apply method below will set the "this" value to callbackObj?
callback.apply (callbackObj, [firstName, lastName]);
}
// The clientData object will be used by the Apply method to set the "this" value?
getUserInput ("Barack", "Obama", clientData.setUserName, clientData);
// the fullName property on the clientData was correctly set?
console.log (clientData.fullName); // Barack Obama
Borrow functions with apply
or call
Borrow Array methods
Let’s create an array-like
object and borrow some array methods to operate on the our array-like object.
// An array-like object: note the non-negative integers used as keys?
var anArrayLikeObj = {0:"Martin", 1:78, 2:67, 3:["Letta", "Marieta", "Pauline"], length:4 };
// Make a quick copy and save the results in a real array:
// First parameter sets the "this" value?
var newArray = Array.prototype.slice.call (anArrayLikeObj, 0);
console.log (newArray); // ["Martin", 78, 67, Array[3]]?
// Search for "Martin" in the array-like object?
console.log (Array.prototype.indexOf.call (anArrayLikeObj, "Martin") === -1 ? false : true); // true?
Another common case is that convert arguments
to array as following
// We do not define the function with any parameters, yet we can get all the arguments passed to it?
function doSomething () {
var args = Array.prototype.slice.call (arguments);
console.log (args);
}
doSomething ("Water", "Salt", "Glue"); // ["Water", "Salt", "Glue"]
Borrow other methods
var gameController = {
scores :[20, 34, 55, 46, 77],
avgScore:null,
players :[
{name:"Tommy", playerID:987, age:23},
{name:"Pau", playerID:87, age:33}
]
}
var appController = {
scores :[900, 845, 809, 950],
avgScore:null,
avg :function () {
var sumOfScores = this.scores.reduce (function (prev, cur, index, array) {
return prev + cur;
});
this.avgScore = sumOfScores / this.scores.length;
}
}
// Note that we are using the apply () method, so the 2nd argument has to be an array?
appController.avg.apply (gameController);
console.log (gameController.avgScore); // 46.4?
// appController.avgScore is still null; it was not updated, only gameController.avgScore was updated?
console.log (appController.avgScore); // null?
Use apply()
to execute variable-arity function
The Math.max
is one example of variable-arity function,
// We can pass any number of arguments to the Math.max () method?
console.log (Math.max (23, 11, 34, 56)); // 56
But what if we have an array of numbers to pass to Math.max
? We cannot do this:
var allNumbers = [23, 11, 34, 56];
// We cannot pass an array of numbers to the the Math.max method like this?
console.log (Math.max (allNumbers)); // NaN
This is where the apply ()
method helps us execute variadic functions. Instead of the above, we have to pass the array of numbers using apply (
) thus:
var allNumbers = [23, 11, 34, 56];
// Using the apply () method, we can pass the array of numbers:
console.log (Math.max.apply (null, allNumbers)); // 56

Here are the few techniques I've heard of:
Use clone()
if the class implements Cloneable
. This API is a bit flawed in java and I never quite understood why clone
is not defined in the interface, but in Object
. Still, it might work.
Create a clone manually. If there is a constructor that accepts all parameters, it might be simple, e.g new User( user.ID, user.Age, ... )
. You might even want a constructor that takes a User: new User( anotherUser ).
Implement something to copy from/to a user. Instead of using a constructor, the class may have a method copy( User )
. You can then first snapshot the object backupUser.copy( user )
and then restore it user.copy( backupUser )
. You might have a variant with methods named backup
/restore
/snapshot
.
Use the state pattern.
Use serialization. If your object is a graph, it might be easier to serialize/deserialize it to get a clone.
That all depends on the use case. Go for the simplest.
EDIT
I also recommend to have a look at these questions:
You can use the opt(int)
method and use a classical for
loop.
Booleans in python are subclass of integer. Constructor of booleans is bool
. bool class inherits from int class.
issubclass(bool,int) // will return True
isinstance(True,bool) , isinstance(False,bool) //they both True
True
and False
are singleton objects. they will retain same memory address throughout the lifetime of your app. When you type True
, python memory manager will check its address and will pull the value '1'. for False
its value is '0'.
Comparisons of any boolean expression to True
or False
can be performed using either is
(identity) or ==
(equality) operator.
int(True) == 1
int(False) == 0
But note that True
and '1' are not the same objects. You can check:
id(True) == id(1) // will return False
you can also easily see that
True > False // returns true cause 1>0
any integer operation can work with the booleans.
True + True + True =3
All objects in python have an associated truth value. Every object has True
value except:
None
False
0 in any numeric type (0,0.0,0+0j etc)
empty sequences (list, tuple, string)
empty mapping types (dictionary, set, etc)
custom classes that implement __bool__
or __len__
method that returns False
or 0
.
every class in python has truth values defined by a special instance method:
__bool__(self) OR
__len__
When you call bool(x)
python will actually execute
x.__bool__()
if instance x
does not have this method, then it will execute
x.__len__()
if this does not exist, by default value is True
.
For Example for int
class we can define bool as below:
def __bool__(self):
return self != 0
for bool(100), 100 !=0
will return True
. So
bool(100) == True
you can easily check that bool(0)
will be False
. with this for instances of int class only 0 will return False.
another example= bool([1,2,3])
[1,2,3]
has no __bool__()
method defined but it has __len__()
and since its length is greater than 0, it will return True
. Now you can see why empty lists return False
.
As @MeBigFatGuy says, except you can make your static {...}
block use a loop over the values()
collection:
static {
for (PcapLinkType type : PcapLinkType.values()) {
intToTypeMap.put(type.getValue(), type);
}
}
The easiest solution is this( do these as root)
sudo su root
cd /etc
mkdir node
yum install wget
wget https://nodejs.org/dist/v9.0.0/node-v9.0.0-linux-x64.tar.gz
tar -xvf node-v9.0.0-linux-x64.tar.gz
cd node-v9.0.0-linux-x64/bin
./node -v
ln -s /etc/node-v9.0.0-linux-x64/bin/node node
You can try ng-file-upload angularjs plugin (instead of ng-upload).
It's fairly easy to setup and deal with angularjs specifics. It also supports progress, cancel, drag and drop and is cross browser.
html
<!-- Note: MUST BE PLACED BEFORE angular.js-->
<script src="ng-file-upload-shim.min.js"></script>
<script src="angular.min.js"></script>
<script src="ng-file-upload.min.js"></script>
<div ng-controller="MyCtrl">
<input type="file" ngf-select="onFileSelect($files)" multiple>
</div>
JS:
//inject angular file upload directives and service.
angular.module('myApp', ['ngFileUpload']);
var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
$scope.onFileSelect = function($files) {
//$files: an array of files selected, each file has name, size, and type.
for (var i = 0; i < $files.length; i++) {
var file = $files[i];
$scope.upload = $upload.upload({
url: 'server/upload/url', //upload.php script, node.js route, or servlet url
data: {myObj: $scope.myModelObj},
file: file,
}).progress(function(evt) {
console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
}).then(function(response) {
var data = response.data;
// file is uploaded successfully
console.log(data);
});
}
};
}];
You can use strip() or split() to control the spaces values as in the following:
words = " first second "
# Remove end spaces
def remove_end_spaces(string):
return "".join(string.rstrip())
# Remove the first and end spaces
def remove_first_end_spaces(string):
return "".join(string.rstrip().lstrip())
# Remove all spaces
def remove_all_spaces(string):
return "".join(string.split())
# Show results
print(words)
print(remove_end_spaces(words))
print(remove_first_end_spaces(words))
print(remove_all_spaces(words))
For those of you with a Chromebook Pixel/Ubuntu/Crouton with no numpad, installing the onboard
keyboard worked for me.
Just press 123 to access the numpad layout, and then press 7
If you're on Unity already, onboard
may already be installed, so just type onboard
from your command line to see if it's there.
If not, just type:
sudo apt-get update
sudo apt-get install onboard
PS: The Chromebook Pixel's upper keys were supposed to represent the traditional F1 through F11 function keys on Ubuntu/Crouton, so you may want to try those special hardware keys first (on their own or in combination with Ctrl). It's just that for me, I'm running an old copy of Crouton, and the only function key that seems to be recognized is F6
This happened to me using react-native run-android because my package name did not match my app ID. Just add --appId YOUR_APP_ID
.
In .Net Core (as of v2.2) it should be:
new Process
{
StartInfo = new ProcessStartInfo(@"file path")
{
UseShellExecute = true
}
}.Start();

As mentioned the size should reflect the current architecture. You could take a peak around in limits.h
if you want to see how your current compiler is handling things.
According to this, you will need .NET 4.5 installed. For more details, visit the webpage. The gist of it is that after you have .NET 4.5 installed, your 4.0 apps will use the 4.5 System.dll. You can enable TLS 1.2 in two ways:
ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319: SchUseStrongCrypto
to DWORD 1
In React-Router v4 and ES6
You can use withRouter
and this.props.history.push
.
import {withRouter} from 'react-router-dom';
class Home extends Component {
componentDidMount() {
this.props.history.push('/redirect-to');
}
}
export default withRouter(Home);
I ran into this issue and resolved it by removing the width styling I had used on the SVG:
.svg-div img {
width: 200px; /* removed this */
height: auto;
}
In your php file just enter this code:
error_reporting(0);
This will report no errors to the user. If you somehow want, then just comment this.
You can use regular expressions for this, so I think this is what you want:
select t.*
from test t
where not regexp_like(sampletext, '.*[^a-zA-Z0-9 .{}\[\]].*')
You can also use Comparator.comparing(Function, Comparator)
It is convenient to chain comparators when necessary, e.g.:
Comparator<SomeEntity> ENTITY_COMPARATOR = comparing(SomeEntity::getProperty1, reverseOrder())
.thenComparingInt(SomeEntity::getProperty2)
.thenComparing(SomeEntity::getProperty3, reverseOrder());
I think the reason that this is happening could be because TextBox1
is scoping to the VBA module and its associated sheet, while Range is scoping to the "Active Sheet".
EDIT
It looks like you may be able to use the GetObject function to pull the textbox from the workbook.
Suppose there are 3 non-negative integers: a
, b
, and c
. Mathematically speaking, if we want to determine if c
is between a
and b
, inclusively, one can use this formula:
(c - a) * (b - c) >= 0
or in Python:
> print((c - a) * (b - c) >= 0)
True
You can capture the system environment variables with a vbs script, but you need a bat script to actually change the current environment variables, so this is a combined solution.
Create a file named resetvars.vbs
containing this code, and save it on the path:
Set oShell = WScript.CreateObject("WScript.Shell")
filename = oShell.ExpandEnvironmentStrings("%TEMP%\resetvars.bat")
Set objFileSystem = CreateObject("Scripting.fileSystemObject")
Set oFile = objFileSystem.CreateTextFile(filename, TRUE)
set oEnv=oShell.Environment("System")
for each sitem in oEnv
oFile.WriteLine("SET " & sitem)
next
path = oEnv("PATH")
set oEnv=oShell.Environment("User")
for each sitem in oEnv
oFile.WriteLine("SET " & sitem)
next
path = path & ";" & oEnv("PATH")
oFile.WriteLine("SET PATH=" & path)
oFile.Close
create another file name resetvars.bat containing this code, same location:
@echo off
%~dp0resetvars.vbs
call "%TEMP%\resetvars.bat"
When you want to refresh the environment variables, just run resetvars.bat
Apologetics:
The two main problems I had coming up with this solution were
a. I couldn't find a straightforward way to export environment variables from a vbs script back to the command prompt, and
b. the PATH environment variable is a concatenation of the user and the system PATH variables.
I'm not sure what the general rule is for conflicting variables between user and system, so I elected to make user override system, except in the PATH variable which is handled specifically.
I use the weird vbs+bat+temporary bat mechanism to work around the problem of exporting variables from vbs.
Note: this script does not delete variables.
This can probably be improved.
ADDED
If you need to export the environment from one cmd window to another, use this script (let's call it exportvars.vbs
):
Set oShell = WScript.CreateObject("WScript.Shell")
filename = oShell.ExpandEnvironmentStrings("%TEMP%\resetvars.bat")
Set objFileSystem = CreateObject("Scripting.fileSystemObject")
Set oFile = objFileSystem.CreateTextFile(filename, TRUE)
set oEnv=oShell.Environment("Process")
for each sitem in oEnv
oFile.WriteLine("SET " & sitem)
next
oFile.Close
Run exportvars.vbs
in the window you want to export from, then switch to the window you want to export to, and type:
"%TEMP%\resetvars.bat"
Simple way to switch wifi on non-rooted devices is to use simple app:
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WifiManager wfm = (WifiManager) getSystemService(Context.WIFI_SERVICE);
try {
wfm.setWifiEnabled(Boolean.parseBoolean(getIntent().getStringExtra("wifi")));
} catch (Exception e) {
}
System.exit(0);
}
}
AndroidManifest.xml:
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
ADB commands:
$ adb shell am start -n org.mytools.config/.MainActivity -e wifi true
$ adb shell am start -n org.mytools.config/.MainActivity -e wifi false
First of all, it's considered bad practice to extend Object.prototype
. Instead, provide your feature as utility function on Object
, just like there already are Object.keys
, Object.assign
, Object.is
, ...etc.
I provide here several solutions:
reduce
and Object.keys
Object.assign
map
and spread syntax instead of reduce
Object.entries
and Object.fromEntries
reduce
and Object.keys
With reduce
and Object.keys
to implement the desired filter (using ES6 arrow syntax):
Object.filter = (obj, predicate) => _x000D_
Object.keys(obj)_x000D_
.filter( key => predicate(obj[key]) )_x000D_
.reduce( (res, key) => (res[key] = obj[key], res), {} );_x000D_
_x000D_
// Example use:_x000D_
var scores = {_x000D_
John: 2, Sarah: 3, Janet: 1_x000D_
};_x000D_
var filtered = Object.filter(scores, score => score > 1); _x000D_
console.log(filtered);
_x000D_
Note that in the above code predicate
must be an inclusion condition (contrary to the exclusion condition the OP used), so that it is in line with how Array.prototype.filter
works.
Object.assign
In the above solution the comma operator is used in the reduce
part to return the mutated res
object. This could of course be written as two statements instead of one expression, but the latter is more concise. To do it without the comma operator, you could use Object.assign
instead, which does return the mutated object:
Object.filter = (obj, predicate) => _x000D_
Object.keys(obj)_x000D_
.filter( key => predicate(obj[key]) )_x000D_
.reduce( (res, key) => Object.assign(res, { [key]: obj[key] }), {} );_x000D_
_x000D_
// Example use:_x000D_
var scores = {_x000D_
John: 2, Sarah: 3, Janet: 1_x000D_
};_x000D_
var filtered = Object.filter(scores, score => score > 1); _x000D_
console.log(filtered);
_x000D_
map
and spread syntax instead of reduce
Here we move the Object.assign
call out of the loop, so it is only made once, and pass it the individual keys as separate arguments (using the spread syntax):
Object.filter = (obj, predicate) => _x000D_
Object.assign(...Object.keys(obj)_x000D_
.filter( key => predicate(obj[key]) )_x000D_
.map( key => ({ [key]: obj[key] }) ) );_x000D_
_x000D_
// Example use:_x000D_
var scores = {_x000D_
John: 2, Sarah: 3, Janet: 1_x000D_
};_x000D_
var filtered = Object.filter(scores, score => score > 1); _x000D_
console.log(filtered);
_x000D_
Object.entries
and Object.fromEntries
As the solution translates the object to an intermediate array and then converts that back to a plain object, it would be useful to make use of Object.entries
(ES2017) and the opposite (i.e. create an object from an array of key/value pairs) with Object.fromEntries
(ES2019).
It leads to this "one-liner" method on Object
:
Object.filter = (obj, predicate) => _x000D_
Object.fromEntries(Object.entries(obj).filter(predicate));_x000D_
_x000D_
// Example use:_x000D_
var scores = {_x000D_
John: 2, Sarah: 3, Janet: 1_x000D_
};_x000D_
_x000D_
var filtered = Object.filter(scores, ([name, score]) => score > 1); _x000D_
console.log(filtered);
_x000D_
The predicate function gets a key/value pair as argument here, which is a bit different, but allows for more possibilities in the predicate function's logic.
You can also access the principal using the User
property on ApiController
.
So the following two statements are basically the same:
string id;
id = User.Identity.GetUserId();
id = RequestContext.Principal.Identity.GetUserId();
A different perspective to the same problem away from Javascript and using php:
<a data-toggle="modal" href="#myModal">LINK</a>
<div class="modal fade" tabindex="-1" aria-labelledby="gridSystemModalLabel" id="myModal" role="dialog" style="max-width: 90%;">
<div class="modal-dialog" style="text-align: left;">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Title</h4>
</div>
<div class="modal-body">
<?php include( 'remotefile.php'); ?>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
and put in the remote.php file your basic html source.
Open the CSV file with a decent text editor like Notepad++ and add the following text in the first line:
sep=,
Now open it with excel again.
This will set the separator as a comma, or you can change it to whatever you need.
git stash show -p | git apply
and then git stash drop
if you want to drop the stashed items.
select id,first_name,gender,age,
rank() over(partition by gender order by age) rank_g

CREATE TABLE person (id int, first_name varchar(20), age int, gender char(1));
INSERT INTO person VALUES (1, 'Bob', 25, 'M');
INSERT INTO person VALUES (2, 'Jane', 20, 'F');
INSERT INTO person VALUES (3, 'Jack', 30, 'M');
INSERT INTO person VALUES (4, 'Bill', 32, 'M');
INSERT INTO person VALUES (5, 'Nick', 22, 'M');
INSERT INTO person VALUES (6, 'Kathy', 18, 'F');
INSERT INTO person VALUES (7, 'Steve', 36, 'M');
INSERT INTO person VALUES (8, 'Anne', 25, 'F');
INSERT INTO person VALUES (9,'AKSH',32,'M');
A very easy way to invoke return and non return value subroutines. is using Func and Action respectively. (see also https://msdn.microsoft.com/en-us/library/018hxwa8(v=vs.110).aspx)
Try this this example
using System;
public class Program
{
private Func<string,string> FunctionPTR = null;
private Func<string,string, string> FunctionPTR1 = null;
private Action<object> ProcedurePTR = null;
private string Display(string message)
{
Console.WriteLine(message);
return null;
}
private string Display(string message1,string message2)
{
Console.WriteLine(message1);
Console.WriteLine(message2);
return null;
}
public void ObjectProcess(object param)
{
if (param == null)
{
throw new ArgumentNullException("Parameter is null or missing");
}
else
{
Console.WriteLine("Object is valid");
}
}
public void Main(string[] args)
{
FunctionPTR = Display;
FunctionPTR1= Display;
ProcedurePTR = ObjectProcess;
FunctionPTR("Welcome to function pointer sample.");
FunctionPTR1("Welcome","This is function pointer sample");
ProcedurePTR(new object());
}
}
Make sure you are loading those modules (myApp.services and myApp.directives) as dependencies of your main app module, like this:
angular.module('myApp', ['myApp.directives', 'myApp.services']);

This is one of the simplest ways to sort record by Date:
SELECT `Article_Id` , `Title` , `Source_Link` , `Content` , `Source` , `Reg_Date`, UNIX_TIMESTAMP( `Reg_Date` ) AS DATE
FROM article
ORDER BY DATE DESC
<a href="javascript:call_func();">...</a>
where the function then has to return false so that the browser doesn't go to another page.
But I'd recommend to use jQuery (with $(...).click(function () {}))
)
my 2 cents
def getResponseCode(url):
conn = urllib.request.urlopen(url)
return conn.getcode()
if getResponseCode(url) != 200:
print('Wrong URL')
else:
print('Good URL')
Assuming that ids are unique and you'll only have to remove the one element splice
should do the trick:
var data = [
{"id":"88","name":"Lets go testing"},
{"id":"99","name":"Have fun boys and girls"},
{"id":"108","name":"You are awesome!"}
],
id = 88;
console.table(data);
$.each(data, function(i, el){
if (this.id == id){
data.splice(i, 1);
}
});
console.table(data);
