Steps:

1. Create a CSR Using Key Chain Access
2. Create a P12 Using Key Chain Access using private key
3. APNS App ID and certificate

This gives you three files:

• The CSR
• The private key as a p12 file (PushChatKey.p12)
• The SSL certificate, aps_development.cer

Go to the folder where you downloaded the files, in my case the Desktop:

$ cd ~/Desktop/

Convert the .cer file into a .pem file:

$ openssl x509 -in aps_development.cer -inform der -out PushChatCert.pem

Convert the private key’s .p12 file into a .pem file:

$ openssl pkcs12 -nocerts -out PushChatKey.pem -in PushChatKey.p12

Enter Import Password:

MAC verified OK Enter PEM pass phrase: Verifying - Enter PEM pass phrase:

You first need to enter the passphrase for the .p12 file so that openssl can read it. Then you need to enter a new passphrase that will be used to encrypt the PEM file. Again for this tutorial I used “pushchat” as the PEM passphrase. You should choose something more secure. Note: if you don’t enter a PEM passphrase, openssl will not give an error message but the generated .pem file will not have the private key in it.

Finally, combine the certificate and key into a single .pem file:

$ cat PushChatCert.pem PushChatKey.pem > ck.pem

It is very simple.

select DATENAME(month, getdate())

output : January

        <Extension()>
    Public Function ToEnum(Of TEnum)(ByVal value As String, ByVal defaultValue As TEnum) As TEnum
        If String.IsNullOrEmpty(value) Then
            Return defaultValue
        End If

        Return [Enum].Parse(GetType(TEnum), value, True)
    End Function

You can run the MySQL command SHOW FULL PROCESSLIST; to see what queries are being processed at any given time, but that probably won't achieve what you're hoping for.

The best method to get a history without having to modify every application using the server is probably through triggers. You could set up triggers so that every query run results in the query being inserted into some sort of history table, and then create a separate page to access this information.

Do be aware that this will probably considerably slow down everything on the server though, with adding an extra INSERT on top of every single query.

Edit: another alternative is the General Query Log, but having it written to a flat file would remove a lot of possibilities for flexibility of displaying, especially in real-time. If you just want a simple, easy-to-implement way to see what's going on though, enabling the GQL and then using running tail -f on the logfile would do the trick.

This is not an error, it is a warning from your Microsoft compiler.

Select your project and click "Properties" in the context menu.

In the dialog, chose Configuration Properties -> C/C++ -> Preprocessor

In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS to turn those warnings off.

Update September 2016

Installing from vanilla https github URLs now works:

npm install https://github.com/fergiemcdowall/search-index.git

EDIT 1: You can't do this for all modules because you are reading from a source control system, which may well contain invalid/uncompiled/buggy code. So to be clear (although it should go without saying): given that the code in the repo is in an npm-usable state, you can now quite happily install directly from github

EDIT 2: (21-10-2019) We are now living through "peak Typescript/React/Babel", and therefore JavaScript compilation has become quite common. If you need to take compilation into account look into prepare. That said, NPM modules do not need to be compiled, and it is wise to assume that compilation is not the default, especially for older node modules (and possibly also for very new, bleeding-edge "ESNext"-y ones).

I have encountered the same problem and now I have an answer I like more (may be you too). I have bounded each checkbox to an array index.

First I defined an Object like this:

SelectionStatusOfMutants: any = {};

Then the checkboxes are like this:

<input *ngFor="let Mutant of Mutants" type="checkbox"
[(ngModel)]="SelectionStatusOfMutants[Mutant.Id]" [value]="Mutant.Id" />

As you know objects in JS are arrays with arbitrary indices. So the result are being fetched so simple:

Count selected ones like this:

let count = 0;
    Object.keys(SelectionStatusOfMutants).forEach((item, index) => {
        if (SelectionStatusOfMutants[item])
            count++;
    });

And similar to that fetch selected ones like this:

let selecteds = Object.keys(SelectionStatusOfMutants).filter((item, index) => {
        return SelectionStatusOfMutants[item];
    });

You see?! Very simple very beautiful. TG.

AndroidManifest file:

    super.onCreate(savedInstanceState);   
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

it's work :]

It happens mostly when JQuery is not installed in your project. Install JQuery in your project by following commands according to your package manager.

Yarn

yarn add jquery

npm

npm i jquery --save

After this just import $ in your project file. import $ from 'jquery'

This is what worked nicely for me since all I wanted to do was set the height of the textbox. The property is Read-Only and the property is in the Unit class so you can't just set it. So I just created a new Unit and the constructor lets me set the height, then set the textbox to that unit instead.

Unit height = txtTextBox.Height;
double oldHeight = height.Value;
double newHeight = height.Value + 20; //Added 20 pixels
Unit newHeightUnit = new Unit(newHeight);
txtTextBox.Height = newHeightUnit;

Use:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= TRUNC(SYSDATE) - 30

SYSDATE returns the date & time; TRUNC resets the date to being as of midnight so you can omit it if you want the creation_date that is 30 days previous including the current time.

Depending on your needs, you could also look at using ADD_MONTHS:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= ADD_MONTHS(TRUNC(SYSDATE), -1)

GZip is simply deflate plus a checksum and header/footer. Deflate is faster, though, as I learned the hard way.

I agree with Brandrew, the problem is most likely caused by some missing dlls that can't be found neither on the system path nor in the folder where the executable is. Try putting the following DLLs nearby the executable:

• the Visual Studio C++ runtime (in VS2008, they could be found at places like C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86.) Include all 3 of the DLL files as well as the manifest file.
• the four OpenCV dlls (cv210.dll, cvaux210.dll, cxcore210.dll and highgui210.dll, or the ones your OpenCV version has)
• if that still doesn't work, try the debug VS runtime (executables compiled for "Debug" use a different set of dlls, named something like msvcrt9d.dll, important part is the "d")

Alternatively, try loading the executable into Dependency Walker ( http://www.dependencywalker.com/ ), it should point out the missing dlls for you.

you can use the new HTML 5 file api to read file contents

https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications

but this won't work on every browser so you probably need a server side fallback.

numpy.ndarray can contain any type of element, e.g. int, float, string etc. Check the type an do a conversion if neccessary.

System.IO.File:

using System.IO;

if (File.Exists(path)) 
{
    Console.WriteLine("file exists");
} 

Perhaps not relevant if you're looking to do this ONLY using ansible. But it's much easier for me to have a function in my .bash_profile and then run _check_machine host1 host2

function _check_machine() {
    echo 'hostname,num_physical_procs,cores_per_procs,memory,Gen,RH Release,bios_hp_power_profile,bios_intel_qpi_link_power_management,bios_hp_power_regulator,bios_idle_power_state,bios_memory_speed,'
    hostlist=$1
    for h in `echo $hostlist | sed 's/ /\n/g'`;
    do
        echo $h | grep -qE '[a-zA-Z]'
        [ $? -ne 0 ] && h=plabb$h
        echo -n $h,
        ssh root@$h 'grep "^physical id" /proc/cpuinfo | sort -u | wc -l; grep "^cpu cores" /proc/cpuinfo |sort -u | awk "{print \$4}"; awk "{print \$2/1024/1024; exit 0}" /proc/meminfo; /usr/sbin/dmidecode | grep "Product Name"; cat /etc/redhat-release; /etc/facter/bios_facts.sh;' | sed 's/Red at Enterprise Linux Server release //g; s/.*=//g; s/\tProduct Name: ProLiant BL460c //g; s/-//g' | sed 's/Red Hat Enterprise Linux Server release //g; s/.*=//g; s/\tProduct Name: ProLiant BL460c //g; s/-//g' | tr "\n" ","
         echo ''
    done
}

E.g.

$ _machine_info '10 20 1036'
hostname,num_physical_procs,cores_per_procs,memory,Gen,RH Release,bios_hp_power_profile,bios_intel_qpi_link_power_management,bios_hp_power_regulator,bios_idle_power_state,bios_memory_speed,
plabb10,2,4,47.1629,G6,5.11 (Tikanga),Maximum_Performance,Disabled,HP_Static_High_Performance_Mode,No_CStates,1333MHz_Maximum,
plabb20,2,4,47.1229,G6,6.6 (Santiago),Maximum_Performance,Disabled,HP_Static_High_Performance_Mode,No_CStates,1333MHz_Maximum,
plabb1036,2,12,189.12,Gen8,6.6 (Santiago),Custom,Disabled,HP_Static_High_Performance_Mode,No_CStates,1333MHz_Maximum,
$ 

Needless to say function won't work for you as it is. You need to update it appropriately.

I think this should require nothing more then just grouping by all columns except the id and choosing one row from every group - for simplicity just the first row, but this does not actually matter besides you have additional constraints on the id.

Or the other way around to get rid of the rows ... just delete all rows accept a single one from all groups.

I needed something similar for a task. This is the code I wrote: It calculates the next day and changes the time to whatever is required and finds seconds between currentTime and next scheduled time.

import datetime as dt

def my_job():
    print "hello world"
nextDay = dt.datetime.now() + dt.timedelta(days=1)
dateString = nextDay.strftime('%d-%m-%Y') + " 01-00-00"
newDate = nextDay.strptime(dateString,'%d-%m-%Y %H-%M-%S')
delay = (newDate - dt.datetime.now()).total_seconds()
Timer(delay,my_job,()).start()

Which version of .NET are you using? If it's .NET 3.5, I'd just call ToArray() and be done with it.

If you only have a non-generic IEnumerable, do something like this:

IEnumerable query = ...;
MyEntityType[] array = query.Cast<MyEntityType>().ToArray();

If you don't know the type within that method but the method's callers do know it, make the method generic and try this:

public static void T[] PerformQuery<T>()
{
    IEnumerable query = ...;
    T[] array = query.Cast<T>().ToArray();
    return array;
}

This will add an image to another.

using (Graphics grfx = Graphics.FromImage(image))
{
    grfx.DrawImage(newImage, x, y)
}

Graphics is in the namespace System.Drawing

The unambiguous way to write this is (i.e. increase the 2nd date by 1 and make it <)

select * 
from xxx 
where dates >= '20121026'
  and dates <  '20121028'

If you're using SQL Server 2008 or above, you can safety CAST as DATE while retaining SARGability, e.g.

select * 
from xxx 
where CAST(dates as DATE) between '20121026' and '20121027'

This explicitly tells SQL Server that you are only interested in the DATE portion of the dates column for comparison against the BETWEEN range.

It failed because you used ajax="false". This fires a full synchronous request which in turn causes a full page reload, causing the oncomplete to be never fired (note that all other ajax-related attributes like process, onstart, onsuccess, onerror and update are also never fired).

That it worked when you removed actionListener is also impossible. It should have failed the same way. Perhaps you also removed ajax="false" along it without actually understanding what you were doing. Removing ajax="false" should indeed achieve the desired requirement.

Also is it possible to execute actionlistener and oncomplete simultaneously?

No. The script can only be fired before or after the action listener. You can use onclick to fire the script at the moment of the click. You can use onstart to fire the script at the moment the ajax request is about to be sent. But they will never exactly simultaneously be fired. The sequence is as follows:

• User clicks button in client
• onclick JavaScript code is executed
• JavaScript prepares ajax request based on process and current HTML DOM tree
• onstart JavaScript code is executed
• JavaScript sends ajax request from client to server
• JSF retrieves ajax request
• JSF processes the request lifecycle on JSF component tree based on process
• actionListener JSF backing bean method is executed
• action JSF backing bean method is executed
• JSF prepares ajax response based on update and current JSF component tree
• JSF sends ajax response from server to client
• JavaScript retrieves ajax response
  • if HTTP response status is 200, onsuccess JavaScript code is executed
  • else if HTTP response status is 500, onerror JavaScript code is executed
• JavaScript performs update based on ajax response and current HTML DOM tree
• oncomplete JavaScript code is executed

Note that the update is performed after actionListener, so if you were using onclick or onstart to show the dialog, then it may still show old content instead of updated content, which is poor for user experience. You'd then better use oncomplete instead to show the dialog. Also note that you'd better use action instead of actionListener when you intend to execute a business action.

OR condition in #ifdef

#if defined LINUX || defined ANDROID
// your code here
#endif /* LINUX || ANDROID */

or-

#if defined(LINUX) || defined(ANDROID)
// your code here
#endif /* LINUX || ANDROID */

Both above are the same, which one you use simply depends on your taste.

P.S.: #ifdef is simply the short form of #if defined, however, does not support complex condition.

Further-

• AND: #if defined LINUX && defined ANDROID
• XOR: #if defined LINUX ^ defined ANDROID

Another option is the CONCAT command:

SELECT CONCAT(MyTable.TextColumn, 'Text') FROM MyTable

I have achieved this in the past by running the "original" code in the "child" and the "spawned" code in the "parent" (that is: you reverse the usual sense of the test after fork()). Then trap SIGCHLD in the "spawned" code...

May not be possible in your case, but cute when it works.

Anybody coming from Manjaro/Arch, installing XAMPP with PHP8 and then downgrading to 7.4 will get this error. To fix, simply go to /opt/lampp/var/mysql/ with Thunar as root user, and delete the database file with the same database name in question and database should be gone. You can get the database name with PhpMyAdmin.

The R file can't be generated if your layout contains errors. If your res folder is empty, then it's safe to assume that there's no res/layout folder with any layouts in it, but your activity is probably calling setContentView and not finding anything -- that qualifies as a problem with your layout.

Are you logging into MySQL as root? You have to explicitly grant privileges to your "regular" MySQL user account while logged in as MySQL root.

First set up a root account for your MySQL database.

In the terminal type:

mysqladmin -u root password 'password'

To log into MySQL, use this:

mysql -u root -p

To set the privileges manually start the server with the skip-grant-tables option, open mysql client and manually update the mysql.user table and/or the mysql.db tables. This can be a tedious task though so if what you need is an account with all privs I would do the following.

Start the server with the skip-grant-tables option

Start mysql client (without a username/password)

Issue the command

flush privileges;

which forces the grant tables to be loaded.

Create a new account with the GRANT command something like this (but replacing username and password with whatever you want to use.

GRANT ALL on *.* to 'username'@'localhost' identified by 'password';

Restart the server in normal mode (without skip-grant-tables) and log in with your newly created account.

Refer this MySQL docs.

As an unordered collection type, set([8, 1, 6]) is equivalent to set([1, 6, 8]).

While it might be nicer to display the set contents in sorted order, that would make the repr() call more expensive.

Internally, the set type is implemented using a hash table: a hash function is used to separate items into a number of buckets to reduce the number of equality operations needed to check if an item is part of the set.

To produce the repr() output it just outputs the items from each bucket in turn, which is unlikely to be the sorted order.

Using Dominic's answer I found the answer to my problem specifically was an invalid DateTiime in the source data before it was applied to the range. Somewhere between the database, .NET and Excel the conversion of the date defaulted down to "1/1/1899 12:00:00 AM". I had to check it and convert it to an empty string and it fixed it for me.

if (objectArray[row, col].ToString() == "1/1/1899 12:00:00 AM")
{
    objectArray[row, col] = string.Empty;
}

This is probably a pretty specific example but hopefully it will save somebody else some time if they are trying to track down a piece of invalid data.

I have never come across a situation where one needs to call a destructor manually. I seem to remember even Stroustrup claims it is bad practice.

1.Install angular-animate

IMHO the biggest advantage that REST enables is that of reducing client/server coupling. It is much easier to evolve a REST interface over time without breaking existing clients.

If you want to use class, you can do this.

Helper.js

  function x(){}

  function y(){}

  export default class Helper{

    static x(){ x(); }

    static y(){ y(); }

  }

App.js

import Helper from 'helper.js';

A great book on REST is REST in Practice.

Must reads are Representational State Transfer (REST) and REST APIs must be hypertext-driven

See Martin Fowlers article the Richardson Maturity Model (RMM) for an explanation on what an RESTful service is.

To be RESTful a Service needs to fulfill the Hypermedia as the Engine of Application State. (HATEOAS), that is, it needs to reach level 3 in the RMM, read the article for details or the slides from the qcon talk.

The HATEOAS constraint is an acronym for Hypermedia as the Engine of Application State. This principle is the key differentiator between a REST and most other forms of client server system.

...

A client of a RESTful application need only know a single fixed URL to access it. All future actions should be discoverable dynamically from hypermedia links included in the representations of the resources that are returned from that URL. Standardized media types are also expected to be understood by any client that might use a RESTful API. (From Wikipedia, the free encyclopedia)

REST Litmus Test for Web Frameworks is a similar maturity test for web frameworks.

Approaching pure REST: Learning to love HATEOAS is a good collection of links.

REST versus SOAP for the Public Cloud discusses the current levels of REST usage.

REST and versioning discusses Extensibility, Versioning, Evolvability, etc. through Modifiability

For people out there asking how to setup proxy server in chrome which needs authentication should follow these steps.

1. Create a proxy.py file in your project, use this code and call proxy_chrome from
   proxy.py everytime you need it. You need to pass parameters like proxy server, port and username password for authentication.

I think you are confused about how the compiler puts things together. When you use -c flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o files thus don't mix with -c, and compiler warns you about that. Symbols from object file are not moved to other object files like that.

All object files should be on the final linker invocation, which is not the case here, so linker (called via g++ front-end) complains about missing symbols.

Here's a small example (calling g++ explicitly for clarity):

PROG ?= myprog
OBJS = worker.o main.o

all: $(PROG)

.cpp.o:
        g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<

$(PROG): $(OBJS)
        g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)

There's also makedepend utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M gcc option for building make rules.

Depending on your situation, the table being locked may just be part of a normal operation & you don't want to just kill the blocking transaction. What you want to do is have your statement wait for the other resource. Oracle 11g has DDL timeouts which can be set to deal with this.

If you're dealing with 10g then you have to get more creative and write some PL/SQL to handle the re-try. Look at Getting around ORA-00054 in Oracle 10g This re-runs your statement when a resource_busy exception occurs.

Have a look at iconv() or mb_convert_encoding(). Just by the way: why don't utf8_encode() and utf8_decode() work for you?

utf8_decode — Converts a string with ISO-8859-1 characters encoded with UTF-8 to single-byte ISO-8859-1

utf8_encode — Encodes an ISO-8859-1 string to UTF-8

So essentially

$utf8 = 'ÄÖÜ'; // file must be UTF-8 encoded
$iso88591_1 = utf8_decode($utf8);
$iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $utf8);
$iso88591_2 = mb_convert_encoding($utf8, 'ISO-8859-1', 'UTF-8');

$iso88591 = 'ÄÖÜ'; // file must be ISO-8859-1 encoded
$utf8_1 = utf8_encode($iso88591);
$utf8_2 = iconv('ISO-8859-1', 'UTF-8', $iso88591);
$utf8_2 = mb_convert_encoding($iso88591, 'UTF-8', 'ISO-8859-1');

all should do the same - with utf8_en/decode() requiring no special extension, mb_convert_encoding() requiring ext/mbstring and iconv() requiring ext/iconv.

If you are using express you need to allow serving of static content by adding something like: var server = express(); server.use(express.static('./public')); // where public is the app root folder, with the fonts contained therein, at any level, i.e. public/fonts or public/dist/fonts... // If you are using connect, google for a similar configuration.

I think by default values read by scanf with space/enter. Well you can provide space between '%d' if you are printing integers. Also same for other cases.

scanf("%d %d %d", &var1, &var2, &var3);

Similarly if you want to read comma separated values use :

scanf("%d,%d,%d", &var1, &var2, &var3);

This will stream the byte data into json.

import io

obj = json.load(io.TextIOWrapper(response))

io.TextIOWrapper is preferred to the codec's module reader. https://www.python.org/dev/peps/pep-0400/

adjust his code:

Object.prototype.each = function(iterateFunc) {
        var counter = 0,
keys = Object.keys(this),
currentKey,
len = keys.length;
        var that = this;
        var next = function() {

            if (counter < len) {
                currentKey = keys[counter++];
                iterateFunc(currentKey, that[currentKey]);

                next();
            } else {
                that = counter = keys = currentKey = len = next = undefined;
            }
        };
        next();
    };

    ({ property1: 'sdsfs', property2: 'chat' }).each(function(key, val) {
        // do things
        console.log(key);
    });

$configValue = Mage::getStoreConfig('sectionName/groupName/fieldName');

sectionName, groupName and fieldName are present in etc/system.xml file of your module.

The above code will automatically fetch config value of currently viewed store.

If you want to fetch config value of any other store than the currently viewed store then you can specify store ID as the second parameter to the getStoreConfig function as below:

$store = Mage::app()->getStore(); // store info
$configValue = Mage::getStoreConfig('sectionName/groupName/fieldName', $store);

Mixins is a concept in Programming in which the class provides functionalities but it is not meant to be used for instantiation. Main purpose of Mixins is to provide functionalities which are standalone and it would be best if the mixins itself do not have inheritance with other mixins and also avoid state. In languages such as Ruby, there is some direct language support but for Python, there isn't. However, you could used multi-class inheritance to execute the functionality provided in Python.

I watched this video http://www.youtube.com/watch?v=v_uKI2NOLEM to understand the basics of mixins. It is quite useful for a beginner to understand the basics of mixins and how they work and the problems you might face in implementing them.

Wikipedia is still the best: http://en.wikipedia.org/wiki/Mixin

The .bash_profile for macOS is found in the $HOME directory. You can create the file if it does not exit. Sublime Text 3 can help.

• If you follow the instruction from OS X Command Line - Sublime Text to launch ST3 with subl then you can just do this

  $ subl ~/.bash_profile
  

• An easier method is to use open

  $ open ~/.bash_profile -a "Sublime Text"
  

Use Command + Shift + . in Finder to view hidden files in your home directory.

Yes. You'd use the urllib2 module, and encode using the multipart/form-data content type. Here is some sample code to get you started -- it's a bit more than just file uploading, but you should be able to read through it and see how it works:

user_agent = "image uploader"
default_message = "Image $current of $total"

    return ''.join (random.choice (string.letters) for ii in range (length + 1))

def encode_multipart_data (data, files):
    boundary = random_string (30)

    def get_content_type (filename):
        return mimetypes.guess_type (filename)[0] or 'application/octet-stream'

    def encode_field (field_name):

Another scenario where this could happen is when you are launching an instance of eclipse (for debug etc.) from a host eclipse - in which case, altering the project's level or JRE library on the project's classpath alone doesn't help. What matters is the JRE used to launch the target eclipse environment.

To see the most recent stash:

git stash show -p

To see an arbitrary stash:

git stash show -p stash@{1}

Also, I use git diff to compare the stash with any branch.

You can use:

git diff stash@{0} master

To see all changes compared to branch master.


Or You can use:

git diff --name-only stash@{0} master

To easy find only changed file names.

From the man git-stash page:

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show

show [<stash>]
       Show the changes recorded in the stash as a diff between the stashed state and
       its original parent. When no <stash> is given, shows the latest one. By default,
       the command shows the diffstat, but it will accept any format known to git diff
       (e.g., git stash show -p stash@{1} to view the second most recent stash in patch
       form).

To list the stashed modifications

git stash list

To show files changed in the last stash

git stash show

So, to view the content of the most recent stash, run

git stash show -p

To view the content of an arbitrary stash, run something like

git stash show -p stash@{1}

location.href = location.href + "&parameter=" + value;

try this

//WITH FIRST COLUMN
arr = arr.sort(function(a,b) {
    return a[0] - b[0];
});


//WITH SECOND COLUMN
arr = arr.sort(function(a,b) {
    return a[1] - b[1];
});

Note: Original answer used a greater than (>) instead of minus (-) which is what the comments are referring to as incorrect.

If you have PowerShell installed (which I recommend), you can use the following command as a rough equivalent (substitute programName for your executable's name):

Considering you're on a feature branch and you want to check which files have changed compared to master... just this:

This error occurs when you're trying to target an element that is wrapped in a condition.

So, here if I use ngIf in place of [hidden], it will give me TypeError: Cannot read property 'nativeElement' of undefined

So use [hidden], class.show or class.hide in place of *ngIf.

SQL Server CONVERT() Function

$x is always a scalar. The hint is the sigil $: any variable (or dereferencing of some other type) starting with $ is a scalar. (See perldoc perldata for more about data types.)

A reference is just a particular type of scalar. The built-in function ref will tell you what kind of reference it is. On the other hand, if you have a blessed reference, ref will only tell you the package name the reference was blessed into, not the actual core type of the data (blessed references can be hashrefs, arrayrefs or other things). You can use Scalar::Util 's reftype will tell you what type of reference it is:

use Scalar::Util qw(reftype);

my $x = bless {}, 'My::Foo';
my $y = { };

print "type of x: " . ref($x) . "\n";
print "type of y: " . ref($y) . "\n";
print "base type of x: " . reftype($x) . "\n";
print "base type of y: " . reftype($y) . "\n";

...produces the output:

type of x: My::Foo
type of y: HASH
base type of x: HASH
base type of y: HASH

For more information about the other types of references (e.g. coderef, arrayref etc), see this question: How can I get Perl's ref() function to return REF, IO, and LVALUE? and perldoc perlref.

Note: You should not use ref to implement code branches with a blessed object (e.g. $ref($a) eq "My::Foo" ? say "is a Foo object" : say "foo not defined";) -- if you need to make any decisions based on the type of a variable, use isa (i.e if ($a->isa("My::Foo") { ... or if ($a->can("foo") { ...). Also see polymorphism.

Use below method, just pass the subject and body as arguments of the method

public static void shareText(String subject,String body) {
    Intent txtIntent = new Intent(android.content.Intent.ACTION_SEND);
    txtIntent .setType("text/plain");
    txtIntent .putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
    txtIntent .putExtra(android.content.Intent.EXTRA_TEXT, body);
    startActivity(Intent.createChooser(txtIntent ,"Share"));
}

API Monitor looks very useful for this purpose.

You can directly access the year and month attributes, or request a datetime.datetime:

In [15]: t = pandas.tslib.Timestamp.now()

In [16]: t
Out[16]: Timestamp('2014-08-05 14:49:39.643701', tz=None)

In [17]: t.to_pydatetime() #datetime method is deprecated
Out[17]: datetime.datetime(2014, 8, 5, 14, 49, 39, 643701)

In [18]: t.day
Out[18]: 5

In [19]: t.month
Out[19]: 8

In [20]: t.year
Out[20]: 2014

One way to combine year and month is to make an integer encoding them, such as: 201408 for August, 2014. Along a whole column, you could do this as:

df['YearMonth'] = df['ArrivalDate'].map(lambda x: 100*x.year + x.month)

or many variants thereof.

I'm not a big fan of doing this, though, since it makes date alignment and arithmetic painful later and especially painful for others who come upon your code or data without this same convention. A better way is to choose a day-of-month convention, such as final non-US-holiday weekday, or first day, etc., and leave the data in a date/time format with the chosen date convention.

The calendar module is useful for obtaining the number value of certain days such as the final weekday. Then you could do something like:

import calendar
import datetime
df['AdjustedDateToEndOfMonth'] = df['ArrivalDate'].map(
    lambda x: datetime.datetime(
        x.year,
        x.month,
        max(calendar.monthcalendar(x.year, x.month)[-1][:5])
    )
)

If you happen to be looking for a way to solve the simpler problem of just formatting the datetime column into some stringified representation, for that you can just make use of the strftime function from the datetime.datetime class, like this:

In [5]: df
Out[5]: 
            date_time
0 2014-10-17 22:00:03

In [6]: df.date_time
Out[6]: 
0   2014-10-17 22:00:03
Name: date_time, dtype: datetime64[ns]

In [7]: df.date_time.map(lambda x: x.strftime('%Y-%m-%d'))
Out[7]: 
0    2014-10-17
Name: date_time, dtype: object

One solution is to run manually a shell function that sets my environment to work or personal, but I am pretty sure that I will often forget to switch to the correct identity resulting in committing under the wrong identity.

That was exactly my problem. I have written a hook script which warns you if you have any github remote and not defined a local username.

Here's how you set it up:

1. Create a directory to hold the global hook

   mkdir -p ~/.git-templates/hooks

2. Tell git to copy everything in ~/.git-templates to your per-project .git directory when you run git init or clone

   git config --global init.templatedir '~/.git-templates'

3. And now copy the following lines to ~/.git-templates/hooks/pre-commit and make the file executable (don't forget this otherwise git won't execute it!)

#!/bin/bash

RED='\033[0;31m' # red color
NC='\033[0m' # no color

GITHUB_REMOTE=$(git remote -v | grep github.com)
LOCAL_USERNAME=$(git config --local user.name)

if [ -n "$GITHUB_REMOTE" ] && [ -z "$LOCAL_USERNAME" ]; then
    printf "\n${RED}ATTENTION: At least one Github remote repository is configured, but no local username. "
    printf "Please define a local username that matches your Github account.${NC} [pre-commit hook]\n\n"
    exit 1
fi

If you use other hosts for your private repositories you have to replace github.com according to your needs.

Now every time you do a git init or git clone git will copy this script to the repository and executes it before any commit is done. If you have not set a local username it will output a warning and won't let you commit.

Assuming you're referring to this plugin, your code should be:

// To Store
$(function() {
    $.session.set("myVar", "value");
});


// To Read
$(function() {
    alert($.session.get("myVar"));
});

Before using a plugin, remember to read its documentation in order to learn how to use it. In this case, an usage example can be found in the README.markdown file, which is displayed on the project page.

Case 1: I was getting this exception when I was trying to create a parent and saving that parent reference to its child and then some other DELETE/UPDATE query(JPQL). So I just flush() the newly created entity after creating parent and after creating child using same parent reference. It Worked for me.

Case 2:

Parent class

public class Reference implements Serializable {

    @Id
    @Column(precision=20, scale=0)
    private BigInteger id;

    @Temporal(TemporalType.TIMESTAMP)
    private Date modifiedOn;

    @OneToOne(mappedBy="reference")
    private ReferenceAdditionalDetails refAddDetails;
    . 
    .
    .
}

Child Class:

public class ReferenceAdditionalDetails implements Serializable{

    private static final long serialVersionUID = 1L;

    @Id
    @OneToOne
    @JoinColumn(name="reference",referencedColumnName="id")
    private Reference reference;

    private String preferedSector1;
    private String preferedSector2;
    .
    .

}

In the above case where parent(Reference) and child(ReferenceAdditionalDetails) having OneToOne relationship and when you try to create Reference entity and then its child(ReferenceAdditionalDetails), it will give you the same exception. So to avoid the exception you have to set null for child class and then create the parent.(Sample Code)

.
.
reference.setRefAddDetails(null);
reference = referenceDao.create(reference);
entityManager.flush();
.
.

var module = angular.module("example", []);

module.controller("orderByController", function ($scope) {
    $scope.orderByValue = function (value) {
        return value;
    };

    $scope.items = ["c", "b", "a"];
    $scope.objList = [
        {
            "name": "c"
        }, {
            "name": "b"
        }, {
            "name": "a"
        }];
        $scope.item = "b";
    });

A regular expression will do the trick with very little code:

import re

...

if re.match("^[A-Za-z0-9_-]*$", my_little_string):

In 99% of the cases, developers with weak system administrator backgrounds ultimately fail to realize the power Microsoft has always provided for anyone to enumerate Windows.

System administrators will always write better and simpler code when it comes to such a point.

Nevertheless, one thing to note, build configuration must be AnyCPU for this environment variable to return the correct values on the correct systems:

System.Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE")

This will return "X86" on 32-bit Windows, and "AMD64" on 64-bit Windows.

The only specific reasons to set autocrlf to true are:

• avoid git status showing all your files as modified because of the automatic EOL conversion done when cloning a Unix-based EOL Git repo to a Windows one (see issue 83 for instance)
• and your coding tools somehow depends on a native EOL style being present in your file:
  • for instance, a code generator hard-coded to detect native EOL
  • other external batches (external to your repo) with regexp or code set to detect native EOL
  • I believe some Eclipse plugins can produce files with CRLF regardless on platform, which can be a problem.
  • You code with Notepad.exe (unless you are using a Windows 10 2018.09+, where Notepad respects the EOL character detected).

Unless you can see specific treatment which must deal with native EOL, you are better off leaving autocrlf to false (git config --global core.autocrlf false).

Note that this config would be a local one (because config isn't pushed from repo to repo)

If you want the same config for all users cloning that repo, check out "What's the best CRLF handling strategy with git?", using the text attribute in the .gitattributes file.

Example:

*.vcproj    text eol=crlf
*.sh        text eol=lf

Note: starting git 2.8 (March 2016), merge markers will no longer introduce mixed line ending (LF) in a CRLF file.
See "Make Git use CRLF on its “<<<<<<< HEAD” merge lines"

The second line should have been pixels[0], with an S. You probably have a tuple named pixel, and tuples are immutable. Construct new pixels instead:

image = Image.open('balloon.jpg')

pixels = [(pix[0] + 20,) + pix[1:] for pix in image.getdata()]

image.putdate(pixels)

In rails 6, simply add this to your controller:

class UsersController < ApplicationController
  include UsersHelper
  
  # Your actions

end

Now the user_helpers.rb will be available in the controller.

df = df.fillna('')

or just

df.fillna('', inplace=True)

This will fill na's (e.g. NaN's) with ''.

If you want to fill a single column, you can use:

df.column1 = df.column1.fillna('')

One can use df['column1'] instead of df.column1.

Change the function that you get one single Result=[array, listp, freep]. So there is only one result to be displayed

Though not widely known, str.endswith also accepts a tuple. You don't need to loop.

>>> 'test.mp3'.endswith(('.mp3', '.avi'))
True

I found another way without setting proxy. I'm currently using an antivirus which has a firewall program. Then, I turn off this firewall and now I can fetch that URL.

If still doesn't work, try to turn off Firewall on your PC, such as Windows Firewall.

If you're like me running in a restricted environment without administrative privileges, that means your only way to get node up and running is to grab the executable (node.exe) without using the installer. You also cannot change the path variable which makes it that much more challenging.

Here's what I did (for Windows)

1. Throw node.exe into its own folder (Downloaded the node.exe stand-alone )
2. Grab an NPM release zip off of github: https://github.com/npm/npm/releases
3. Create a folder named: node_modules in the node.exe folder
4. Extract the NPM zip into the node_modules folder
5. Make sure the top most folder is named npm (remove any of the versioning on the npm folder name ie: npm-2.12.1 --> npm)
6. Copy npm.cmd out of the npm/bin folder into the top most folder with node.exe
7. Open a command prompt to the node.exe directory (shift right-click "Open command window here")
8. Now you will be able to run your npm installers via: npm install -g express

Running the installers through npm will now auto install packages where they need to be located (node_modules and the root)

Don't forget you will not be able to set the path variable if you do not have proper permissions. So your best route is to open a command prompt in the node.exe directory (shift right-click "Open command window here")

Only a few characters in the Windows code page 1252 (Latin-1) are not allowed as names. Note that the Windows Explorer will strip leading spaces from names and not allow you to call a files space dot something (like ?.txt), although this is allowed in the file system! Only a space and no file extension is invalid however.

If you create files through e.g. a Python script (this is what I did), then you can easily find out what is actually allowed and in what order the characters get sorted. The sort order varies based on your locale! Below are the results of my script, run with Python 2.7.15 on a German Windows 10 Pro 64bit:

Screenshot of how Explorer sorts the files for me:

The highlighted file with the ? white smiley face was added manually by me (Alt+1) to show where this Unicode character (U+263A) ends up, see Jimbugs' answer.

The first file has a space as name (0x20), the second is the non-breaking space (0xa0). The files in the bottom half of the third row which look like they have no name use the characters with hex codes 0x81, 0x8D, 0x8F, 0x90, 0x9D (in this order from top to bottom).

Maybe not integers but small unique keys, anyway shorter then guids:

Yes - Unit Testing is definitely worth the effort but you should know it's not a silver bullet. Unit Testing is work and you will have to work to keep the test updated and relevant as code changes but the value offered is worth the effort you have to put in. The ability to refactor with impunity is a huge benefit as you can always validate functionality by running your tests after any change code. The trick is to not get too hung up on exactly the unit-of-work you're testing or how you are scaffolding test requirements and when a unit-test is really a functional test, etc. People will argue about this stuff for hours on end and the reality is that any testing you do as your write code is better than not doing it. The other axiom is about quality and not quantity - I have seen code-bases with 1000's of test that are essentially meaningless as the rest don't really test anything useful or anything domain specific like business rules, etc of the particular domain. I've also seen codebases with 30% code coverage but the tests were relevant, meaningful and really awesome as they tested the core functionality of the code it was written for and expressed how the code should be used.

One of my favorite tricks when exploring new frameworks or codebases is to write unit-tests for 'it' to discover how things work. It's a great way to learn more about something new instead of reading a dry doc :)

1. Open web.config in the directory where the old pages reside

2. Then add code for the old location path and new destination as follows:

   <configuration>
     <location path="services.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/services" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
     <location path="products.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/products" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
   </configuration>
   

You may add as many location paths as necessary.

SELECT field1, 
       field2,
       'example' AS newfield
FROM TABLE1

This will add a column called "newfield" to the output, and its value will always be "example".

you can run this small php code

<?php
phpinfo();
?>

Copy the whole output page, paste it in this link. Then analyze. It will show if Xdebug is installed or not. And it will give instructions to complete the installation.

The .Cells range isn't limited to ones that are being used, so your code is clearing the content of 1,048,576 rows and 16,384 columns - 17,179,869,184 total cells. That's going to take a while. Just clear the UsedRange instead:

Sheets("Zeros").UsedRange.ClearContents

Alternately, you can delete the sheet and re-add it:

Application.DisplayAlerts = False
Sheets("Zeros").Delete
Application.DisplayAlerts = True
Dim sheet As Worksheet
Set sheet = Sheets.Add
sheet.Name = "Zeros"

<?php
$php_multi_array = array("lang"=>"PHP", "type"=>array("c_type"=>"MULTI", "p_type"=>"ARRAY"));

//Iterate through an array declared above

foreach($php_multi_array as $key => $value)
{
    if (!is_array($value))
    {
        echo $key ." => ". $value ."\r\n" ;
    }
    else
    {
       echo $key ." => array( \r\n";

       foreach ($value as $key2 => $value2)
       {
           echo "\t". $key2 ." => ". $value2 ."\r\n";
       }

       echo ")";
    }
}
?>

OUTPUT:

lang => PHP
type => array( 
    c_type => MULTI
    p_type => ARRAY
)

Reference Source Code

You can do it from adb using this command:

adb shell am start -a android.intent.action.DELETE -d package:<your app package>

An auto-updated column is automatically updated to the current timestamp when the value of any other column in the row is changed from its current value. An auto-updated column remains unchanged if all other columns are set to their current values.

To explain it let's imagine you have only one row:

-------------------------------
| price | updated_at          |
-------------------------------
|  2    | 2018-02-26 16:16:17 |
-------------------------------

Now, if you run the following update column:

 update my_table
 set price = 2

it will not change the value of updated_at, since price value wasn't actually changed (it was already 2).

But if you have another row with price value other than 2, then the updated_at value of that row (with price <> 3) will be updated to CURRENT_TIMESTAMP.

(1) This just happened to me, and I thought it was interesting how it happened. Basically I had copied the folder to a new location and modified it, forgetting that it would bring along all the hidden .svn directories. Once you realize how it happens it is easier to avoid in the future.

(2) Removing the .svn directories is the solution, but you have to do it recursively all the way down the directory tree. The easiest way to do that is:

find troublesome_folder -name .svn -exec rm -rf {} \;

Do note that it needs to be in the numeric data type in the first place.

 import pandas as pd
 df['column'] = pd.to_numeric(df['column'], errors='coerce')

Next find the mean on one column or for all numeric columns using describe().

df['column'].mean()
df.describe()

Example of result from describe:

          column 
count    62.000000 
mean     84.678548 
std     216.694615 
min      13.100000 
25%      27.012500 
50%      41.220000 
75%      70.817500 
max    1666.860000

I surggest using the CopyTo method, so here is my two cent on a solution that is easy to explain and simple. The CopyTo method copies the array to another array at a given index. In this case myArray is copied to newArr starting at index 1 so index 0 in newArr can hold the new value.

"Push" to array online demo

var newValue = 1;
var myArray = new int[5] { 2, 3, 4, 5, 6 };
var newArr = new int[myArray.Length + 1];

myArray.CopyTo(newArr, 1);
newArr[0] = newValue;
    
//debug
for(var i = 0; i < newArr.Length; i++){
    Console.WriteLine(newArr[i].ToString());
}

//output
1
2
3
4
5
6

This is also possible with Notepad++:

• Go to the search menu, Ctrl + F, and open the Mark tab.

• Check Bookmark line (if there is no Mark tab update to the current version).

• Enter your search term and click Mark All

  • All lines containing the search term are bookmarked.

• Now go to the menu Search → Bookmark → Remove Bookmarked lines

• Done.

It may be little late but here are my two cents.

If you are using Java 8 then you can make use of computeIfPresent method. If the value for the specified key is present and non-null then it attempts to compute a new mapping given the key and its current mapped value.

final Map<String,Integer> map1 = new HashMap<>();
map1.put("A",0);
map1.put("B",0);
map1.computeIfPresent("B",(k,v)->v+1);  //[A=0, B=1]

We can also make use of another method putIfAbsent to put a key. If the specified key is not already associated with a value (or is mapped to null) then this method associates it with the given value and returns null, else returns the current value.

In case the map is shared across threads then we can make use of ConcurrentHashMap and AtomicInteger. From the doc:

An AtomicInteger is an int value that may be updated atomically. An AtomicInteger is used in applications such as atomically incremented counters, and cannot be used as a replacement for an Integer. However, this class does extend Number to allow uniform access by tools and utilities that deal with numerically-based classes.

We can use them as shown:

final Map<String,AtomicInteger> map2 = new ConcurrentHashMap<>();
map2.putIfAbsent("A",new AtomicInteger(0));
map2.putIfAbsent("B",new AtomicInteger(0)); //[A=0, B=0]
map2.get("B").incrementAndGet();    //[A=0, B=1]

One point to observe is we are invoking get to get the value for key B and then invoking incrementAndGet() on its value which is of course AtomicInteger. We can optimize it as the method putIfAbsent returns the value for the key if already present:

map2.putIfAbsent("B",new AtomicInteger(0)).incrementAndGet();//[A=0, B=2]

On a side note if we plan to use AtomicLong then as per documentation under high contention expected throughput of LongAdder is significantly higher, at the expense of higher space consumption. Also check this question.

The above solutions like run a query

SET session wait_timeout=600;

Will only work until mysql is restarted. For a persistant solution, edit mysql.conf and add after [mysqld]:

wait_timeout=300
interactive_timeout = 300

Where 300 is the number of seconds you want.

I want to chime in here even though this question has already been answered correctly by @pscl in case anyone else runs into the same issue I did. Out of the 4 methods give I chose to use the es6 syntax with arrow functions due to it's conciseness and lack of dependence on external libraries:

Using Array.prototype.filter with ES6 Arrow Functions

removeItem(index) {
  this.setState((prevState) => ({
    data: prevState.data.filter((_, i) => i != index)
  }));
}

As you can see I made a slight modification to ignore the type of index (!== to !=) because in my case I was retrieving the index from a string field.

Another helpful point if you're seeing weird behavior when removing an element on the client side is to NEVER use the index of an array as the key for the element:

// bad
{content.map((content, index) =>
  <p key={index}>{content.Content}</p>
)}

When React diffs with the virtual DOM on a change, it will look at the keys to determine what has changed. So if you're using indices and there is one less in the array, it will remove the last one. Instead, use the id's of the content as keys, like this.

// good
{content.map(content =>
  <p key={content.id}>{content.Content}</p>
)}

The above is an excerpt from this answer from a related post.

Happy Coding Everyone!

For checking one date is after another by using isAfter() method.

moment('2020-01-20').isAfter('2020-01-21'); // false
moment('2020-01-20').isAfter('2020-01-19'); // true

For checking one date is before another by using isBefore() method.

moment('2020-01-20').isBefore('2020-01-21'); // true
moment('2020-01-20').isBefore('2020-01-19'); // false

For checking one date is same as another by using isSame() method.

moment('2020-01-20').isSame('2020-01-21'); // false
moment('2020-01-20').isSame('2020-01-20'); // true

It can also be useful to use String.Format, e.g.

String.Format("{0}\t{1}", FirstName,Count);

You could whip up a little helper function to do this:

/**
 * Determines if $number is between $min and $max
 *
 * @param  integer  $number     The number to test
 * @param  integer  $min        The minimum value in the range
 * @param  integer  $max        The maximum value in the range
 * @param  boolean  $inclusive  Whether the range should be inclusive or not
 * @return boolean              Whether the number was in the range
 */
function in_range($number, $min, $max, $inclusive = FALSE)
{
    if (is_int($number) && is_int($min) && is_int($max))
    {
        return $inclusive
            ? ($number >= $min && $number <= $max)
            : ($number > $min && $number < $max) ;
    }

    return FALSE;
}

And you would use it like so:

var_dump(in_range(5, 0, 10));        // TRUE
var_dump(in_range(1, 0, 1));         // FALSE
var_dump(in_range(1, 0, 1, TRUE));   // TRUE
var_dump(in_range(11, 0, 10, TRUE)); // FALSE

// etc...

Hello this is my first time posting so please be patient: my answer was to create a simple property:

public bool Checked { get; set; }

Then to set the data context of the Checkbox (called cb1):

cb1.DataContext = this;

Then to bind the IsChecked proerty of it in the xaml

IsChecked="{Binding Checked}"

The code is like this:

XAML

<CheckBox x:Name="cb1"
          HorizontalAlignment="Left"
          Margin="439,81,0,0"
          VerticalAlignment="Top"
          Height="35" Width="96"
          IsChecked="{Binding Checked}"/>

Code behind

public partial class MainWindow : Window
{
    public bool Checked { get; set; }

    public MainWindow()
    {
        InitializeComponent();

        cb1.DataContext = this;
    }

    private void myyButton_Click(object sender, RoutedEventArgs e)
    {
        MessageBox.Show(Checked.ToString());
    }
}

on ubuntu:

sudo apt-get install php-mysql
sudo service apache2 restart

The AngularJS documentation on directives is pretty well written for what the symbols mean.

To be clear, you cannot just have

scope: '@'

in a directive definition. You must have properties for which those bindings apply, as in:

scope: {
    myProperty: '@'
}

I strongly suggest you read the documentation and the tutorials on the site. There is much more information you need to know about isolated scopes and other topics.

Here is a direct quote from the above-linked page, regarding the values of scope:

The scope property can be true, an object or a falsy value:

• falsy: No scope will be created for the directive. The directive will use its parent's scope.

• true: A new child scope that prototypically inherits from its parent will be created for the directive's element. If multiple directives on the same element request a new scope, only one new scope is created. The new scope rule does not apply for the root of the template since the root of the template always gets a new scope.

• {...} (an object hash): A new "isolate" scope is created for the directive's element. The 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent scope. This is useful when creating reusable components, which should not accidentally read or modify data in the parent scope.

The same problem I faced in my project. Thanks to @Umar Rashed, but I am going to explain it in detail.

First, Provide Date Pipe from app.module:

providers: [DatePipe]

Import to your component and app.module:

import { DatePipe } from '@angular/common';

Second, declare it under the constructor:

constructor(
    public datepipe: DatePipe
  ) {

Dates come from the server and parsed to console like this:

2000-09-19T00:00:00

I convert the date to how I need with this code; in TypeScript:

this.datepipe.transform(this.birthDate, 'dd/MM/yyyy')

Show from HTML template:

{{ user.birthDate }}

and it is seen like this:

19/09/2000

also seen on the web site like this: dates shown as it is filtered (click to see the screenshot)

Hi I found the easiest way to do this.

1. Create a new project with the desired package name
2. copy all files from old project to new project (all file in old.bad.oldpackage=>new.fine.newpackage, res=>res)
3. copy old build.graddle inside new build.graddle
4. copy old Manifest inside new Manifest

Unicode is a standard which maps the characters in all languages to a particular numeric value called Code Points. The reason it does this is that it allows different encodings to be possible using the same set of code points.

UTF-8 and UTF-16 are two such encodings. They take code points as input and encodes them using some well-defined formula to produce the encoded string.

Choosing a particular encoding depends upon your requirements. Different encodings have different memory requirements and depending upon the characters that you will be dealing with, you should choose the encoding which uses the least sequences of bytes to encode those characters.

For more in-depth details about Unicode, UTF-8 and UTF-16, you can check out this article,

What every programmer should know about Unicode

You can of course format the result of current_timestamp(). Please have a look at the various formatting functions in the official documentation.

You can take a look also at C++ Builder XE6, and XE7 supports android in c++ code, and with Firemonkey library.

Pretty easy way to start, and native code. But the binaries have a big size.

Try print(e.message) this should be able to print your exception.

try:
    connection = manager.connect("I2Cx")
except Exception, e:
    print(e.message)

my_list = [line.split(',') for line in open("filename.txt")]

 dt = datetime.datetime(*t[:7])

below method helps to convert string to secure string

private SecureString ConvertToSecureString(string password)
{
    if (password == null)
        throw new ArgumentNullException("password");

    var securePassword = new SecureString();

    foreach (char c in password)
        securePassword.AppendChar(c);

    securePassword.MakeReadOnly();
    return securePassword;
}

I'd recommend the Range object's AutoFill method for this:

rngSource.AutoFill Destination:=rngDest

Specify the Source range that contains the values or formulas you want to fill down, and the Destination range as the whole range that you want the cells filled to. The Destination range must include the Source range. You can fill across as well as down.

It works exactly the same way as it would if you manually "dragged" the cells at the corner with the mouse; absolute and relative formulas work as expected.

Here's an example:

'Set some example values'
Range("A1").Value = "1"
Range("B1").Formula = "=NOW()"
Range("C1").Formula = "=B1+A1"

'AutoFill the values / formulas to row 20'
Range("A1:C1").AutoFill Destination:=Range("A1:C20")

Hope this helps.

I had some struggle to access the previous url inside a guard.
Without implementing a custom solution, this one is working for me.

public constructor(private readonly router: Router) {
};

public ngOnInit() {
   this.router.getCurrentNavigation().previousNavigation.initialUrl.toString();
}

The initial url will be the previous url page.

I don't know anything about EF really, but in LINQ to SQL you usually express a LIKE clause using String.Contains:

where entity.Name.Contains("xyz")

translates to

WHERE Name LIKE '%xyz%'

(Use StartsWith and EndsWith for other behaviour.)

I'm not entirely sure whether that's helpful, because I don't understand what you mean when you say you're trying to implement LIKE. If I've misunderstood completely, let me know and I'll delete this answer :)

we can do like this:

in application.yml:

spring:
  profiles:
    active: test //modify here to switch between environments
    include:  application-${spring.profiles.active}.yml

in application-test.yml:

server:
  port: 5000

and in application-local.yml:

server:
  address: 0.0.0.0
  port: 8080

then spring boot will start our app as we wish to.

Header fields are not copied to subsequent requests. You should use either cookie for this (addCookie method) or store "REMOTE_USER" in session (which you can obtain with getSession method).

In your special case it would be

a=$('[myc="blue"][myid="1"],[myc="blue"][myid="3"]');

distcc can also be used to distribute compiles not only on the current machine, but also on other machines in a farm that have distcc installed.

ddList.Items.FindByText("oldValue").Selected = false;
ddList.Items.FindByText("newValue").Selected = true;

You can do

document.getElementById(id) or 
$(id).length > 0

????????????????????? /sdcard/Download ???????? API ?????????????,?? API 22,?????:Settings > Device:Storage & USB > Internal Storage > Explore(?? SD ?)?

and use Drag and Drop actually worked, but use android self installed app Download, then you can NOT find the copied file, for not exist so called /sdcard/Download folder.

finally using other file manager app, like

ES File Explorer

then can see the really path is

/storage/emulated/0/Download/

which contains the copied files, like

/storage/emulated/0/Download/chenhongyu_lixiangsanxun.mp3

after drag and drop more mp3 files:

Labels for break and continue were proposed in PEP 3136 back in 2007, but it was rejected. The Motivation section of the proposal illustrates several common (if inelegant) methods for imitating labeled break in Python.

Try this:

a = 1
b = 2
int_div  = a // b

YES, PUT, DELETE, HEAD etc HTTP methods are available in all modern browsers.

To be compliant with XMLHttpRequest Level 2 browsers must support these methods. To check which browsers support XMLHttpRequest Level 2 I recommend CanIUse:

http://caniuse.com/#feat=xhr2

Only Opera Mini is lacking support atm (juli '15), but Opera Mini lacks support for everything. :)

I routinely multiply by 1.0 if I want floating point, it's easier than remembering the rules.

Use the RIGHT() function: http://msdn.microsoft.com/en-us/library/ms177532(v=sql.105).aspx

SELECT RIGHT( '1234567890', 4 ); -- returns '7890'

git merge

you can follow below steps

1. merge origin/master branch to feature branch

# step1: change branch to master, and pull to update all commits
$ git checkout master
$ git pull

# step2: change branch to target, and pull to update commits
$ git checkout feature
$ git pull

# step3: merge master to feature(?? current is feature branch)
$ git merge master

2. merge feature branch to origin/master branch

origin/master is the remote master branch, while master is the local master branch

$ git checkout master
$ git pull origin/master

$ git merge feature
$ git push origin/master

Your original file probably had no newline character.

However, some editors like gedit in linux silently adds newline at end of file. You cannot get rid of this message while using this kind of editors.

What I tried to overcome this issue is to open file with visual studio code editor

This editor clearly shows the last line and you can delete the line as you wish.

The latest version from Red Gate is 6.1. However the 5.1 version cannot automatically update to version 6 because there were changes to the Terms of Service, so instead you are redirected to the site to download the 6.1 version. This is mostly because of legal reasons as you can check in the following post:

Oi! What's going on with the .NET Reflector update mechanism?

After you manually update to 6.1 you will no longer experience any problems.

Another situation which issues the same problem, map.entrySet().iterator().next()

If there is no element in the Map object, then the above code will return NoSuchElementException. Make sure to call hasNext() first.

For Xamarin Developers, you can use:

intent.SetFlags(ActivityFlags.NewTask | ActivityFlags.ClearTask);

This worked for me:

<button #loginButton ...

and inside the controller:

@ViewChild('loginButton') loginButton;
...
this.loginButton.getNativeElement().click();

Just remove the throw from the catch block — change it to an echo or otherwise handle the error.

It's not telling you that objects can only be thrown in the catch block, it's telling you that only objects can be thrown, and the location of the error is in the catch block — there is a difference.

In the catch block you are trying to throw something you just caught — which in this context makes little sense anyway — and the thing you are trying to throw is a string.

A real-world analogy of what you are doing is catching a ball, then trying to throw just the manufacturer's logo somewhere else. You can only throw a whole object, not a property of the object.

I had an issue with the downscaleImage() function posted above by @daniel-allen-langdon in that the image.width and image.height properties are not available immediately because the image load is asynchronous.

Please see updated TypeScript example below that takes this into account, uses async functions, and resizes the image based on the longest dimension rather than just the width

function getImage(dataUrl: string): Promise<HTMLImageElement> 
{
    return new Promise((resolve, reject) => {
        const image = new Image();
        image.src = dataUrl;
        image.onload = () => {
            resolve(image);
        };
        image.onerror = (el: any, err: ErrorEvent) => {
            reject(err.error);
        };
    });
}

export async function downscaleImage(
        dataUrl: string,  
        imageType: string,  // e.g. 'image/jpeg'
        resolution: number,  // max width/height in pixels
        quality: number   // e.g. 0.9 = 90% quality
    ): Promise<string> {

    // Create a temporary image so that we can compute the height of the image.
    const image = await getImage(dataUrl);
    const oldWidth = image.naturalWidth;
    const oldHeight = image.naturalHeight;
    console.log('dims', oldWidth, oldHeight);

    const longestDimension = oldWidth > oldHeight ? 'width' : 'height';
    const currentRes = longestDimension == 'width' ? oldWidth : oldHeight;
    console.log('longest dim', longestDimension, currentRes);

    if (currentRes > resolution) {
        console.log('need to resize...');

        // Calculate new dimensions
        const newSize = longestDimension == 'width'
            ? Math.floor(oldHeight / oldWidth * resolution)
            : Math.floor(oldWidth / oldHeight * resolution);
        const newWidth = longestDimension == 'width' ? resolution : newSize;
        const newHeight = longestDimension == 'height' ? resolution : newSize;
        console.log('new width / height', newWidth, newHeight);

        // Create a temporary canvas to draw the downscaled image on.
        const canvas = document.createElement('canvas');
        canvas.width = newWidth;
        canvas.height = newHeight;

        // Draw the downscaled image on the canvas and return the new data URL.
        const ctx = canvas.getContext('2d')!;
        ctx.drawImage(image, 0, 0, newWidth, newHeight);
        const newDataUrl = canvas.toDataURL(imageType, quality);
        return newDataUrl;
    }
    else {
        return dataUrl;
    }

}

I tried something and got this error Error: ENOENT: no such file or directory, open 'D:\Website\Nodemailer\Nodemailer-application\views\layouts\main.handlebars'

The fix I got was to literally construct the directory as it is seen. This means labeling the items exactly as shown, It is weird that I gave the computer what it wants.

It would return NULL but if taken as BIGINT would show the number

Bit old question now, but if somebody is looking for solution this works for me.

using Excel = Microsoft.Office.Interop.Excel;

Excel.ApplicationClass excel = new Excel.ApplicationClass();
Excel.Application app = excel.Application;
Excel.Range all = app.get_Range("A1:H10", Type.Missing);

You can use Id of the field as well

$('#checkbox1').change(function() {
   if($(this).is(":checked")) {
      //'checked' event code
      return;
   }
   //'unchecked' event code
});

Multiply the value you want to insert (ex. 2.99) by 100

Then insert the division by 100 of the result adding .01 to the end:

299.01/100

Try this:

Create a model called Profile and reference the user with a OneToOneField and provide an option of related_name.

models.py

from django.db import models
from django.contrib.auth.models import *
from django.dispatch import receiver
from django.db.models.signals import post_save

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='user_profile')

    def __str__(self):
        return self.user.username

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    try:
        if created:
            Profile.objects.create(user=instance).save()
    except Exception as err:
        print('Error creating user profile!')

Now to directly access the profile using a User object you can use the related_name.

views.py

from django.http import HttpResponse

def home(request):
    profile = f'profile of {request.user.user_profile}'
    return HttpResponse(profile)

ALTER tablename MODIFY columnName newColumnType

I'm not sure how it will handle the change from datetime to varchar though, so you may need to rename the column, add a new one with the old name and the correct data type (varchar) and then write an update query to populate the new column from the old.

http://www.1keydata.com/sql/sql-alter-table.html

Because this is javascript and dynamic you could define your own class that matches the File interface and use that instead.

I had to do just that with dropzone.js because I wanted to simulate a file upload and it works on File objects.

Since you look like you're going to be using this in a linux/cygwin environment, you want to use popen. It's like opening a file, only you'll get the executing programs stdout, so you can use your normal fscanf, fread etc.

Make sure you aren't using a Windows' directory separator character (backslash) in your path names in your .conf file, even if you are on Windows. Apache doesn't understand them but will still start up and then output a 403 Forbidden Message.

wrong:

<Directory "c:\websites\my-website\">

right:

<Directory "c:/websites/my-website/">

Javascript is pretty good at manipulating css.

 document.body.style.cursor = *cursor-url*;
 //OR
 var elementToChange = document.getElementsByTagName("body")[0];
 elementToChange.style.cursor = "url('cursor url with protocol'), auto";

or with jquery:

$("html").css("cursor: url('cursor url with protocol'), auto");

Firefox will not work unless you specify a default cursor after the imaged one!

other cursor keywords

Also remember that IE6 only supports .cur and .ani cursors.

If cursor doesn't change: In case you are moving the element under the cursor relative to the cursor position (e.g. element dragging) you have to force a redraw on the element:

// in plain js
document.getElementById('parentOfElementToBeRedrawn').style.display = 'none';
document.getElementById('parentOfElementToBeRedrawn').style.display = 'block';
// in jquery
$('#parentOfElementToBeRedrawn').hide().show(0);

working sample:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>First jQuery-Enabled Page</title>
<style type="text/css">

div {
    height: 100px;
    width: 1000px;
    background-color: red;
}

</style>
<script type="text/javascript" src="jquery-1.3.2.js"></script></head>
<body>
<div>
hello with a fancy cursor!
</div>
</body>
<script type="text/javascript">
document.getElementsByTagName("body")[0].style.cursor = "url('http://wiki-devel.sugarlabs.org/images/e/e2/Arrow.cur'), auto";


</script>
</html>

Anchors will need to be a different display type than their default to take a height. display:inline-block; or display:block;.

Also check on line-height which might be interesting with this.

This happened to me because I enabled usb debug previously on another pc. So to mke it work on a second pc I had to disable usb debugging and re-enable it while connected to the second pc and it worked.

I know you said you would prefer a GUI, but the commandline tools will do the work nicely. See GnuWin for a port of unix tools to Windows. You'd need the patch command, obviously ;-)

You might run into a problem with the line termination, though. The GnuWin port will assume that the patchfile has DOS style line termination (CR/LF). Try to open the patchfile in a reasonably smart editor and it will convert it for you.

The most common mistake (especially when using express) to the "my insert didn't happen" is : looking in the wrong file.

If you are using file-based express (rather than strongly attached), then the file in your project folder (say, c:\dev\myproject\mydb.mbd) is not the file that is used in your program. When you build, that file is copied - for example to c:\dev\myproject\bin\debug\mydb.mbd; your program executes in the context of c:\dev\myproject\bin\debug\, and so it is here that you need to look to see if the edit actually happened. To check for sure: query for the data inside the application (after inserting it).

Json.NET - Documentation

http://james.newtonking.com/json/help/index.html?topic=html/SelectToken.htm

Interpretation for the author

var o = JObject.Parse(response);
var a = o.SelectToken("data").Select(jt => jt.ToObject<TheUser>()).ToList();

You should try and avoid jQuery in ReactJS. But if you really want to use it, you'd put it in componentDidMount() lifecycle function of the component.

e.g.

class App extends React.Component {
  componentDidMount() {
    // Jquery here $(...)...
  }

  // ...
}

Ideally, you'd want to create a reusable Accordion component. For this you could use Jquery, or just use plain javascript + CSS.

class Accordion extends React.Component {
  constructor() {
    super();
    this._handleClick = this._handleClick.bind(this);
  }

  componentDidMount() {
    this._handleClick();
  }

  _handleClick() {
    const acc = this._acc.children;
    for (let i = 0; i < acc.length; i++) {
      let a = acc[i];
      a.onclick = () => a.classList.toggle("active");
    }
  }

  render() {
    return (
      <div 
        ref={a => this._acc = a} 
        onClick={this._handleClick}>
        {this.props.children}
      </div>
    )
  }
}

Then you can use it in any component like so:

class App extends React.Component {
  render() {
    return (
      <div>
        <Accordion>
          <div className="accor">
            <div className="head">Head 1</div>
            <div className="body"></div>
          </div>
        </Accordion>
      </div>
    );
  }
}

Following command worked for me, all the local committed changes are dropped & local is reset to the same as remote origin/master branch.

git reset --hard origin

You may also want to use Rake::FileList (provided you have rake dependency):

FileList.new('lib/*') do |file|
  p file
end

According to the API:

FileLists are lazy. When given a list of glob patterns for possible files to be included in the file list, instead of searching the file structures to find the files, a FileList holds the pattern for latter use.

https://docs.ruby-lang.org/en/2.1.0/Rake/FileList.html

As one person may have already suggested,

I passed the ISO 8601 date string directly to moment like so...

`moment.utc('2019-11-03T05:00:00.000Z').format('MM/DD/YYYY')`

or

`moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')`

either of these solutions will give you the same result.

`console.log(moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')) // 11/3/2019`

Run rails g migration ChangesNameInUsers (or whatever you would like to name it)

Open the migration file that has just been generated, and add this line in the method (in between def change and end):

rename_column :table_name, :the_name_you_want_to_change, :the_new_name

Save the file, and run rake db:migrate in the console

Check out your schema.db in order to see if the name has actually changed in the database!

Hope this helps :)

I also like the solution that you just post an extra input field, using JavaScript seems a little hacky to me.

Depending on what you use for you backend will depend on which input goes first.

For a server backend where the first occurrence is used (JSP) you should do the following.

  <input type="checkbox" value="1" name="checkbox_1"/>
  <input type="hidden" value="0" name="checkbox_1"/>

For a server backend where the last occurrence is used (PHP,Rails) you should do the following.

  <input type="hidden" value="0" name="checkbox_1"/>
  <input type="checkbox" value="1" name="checkbox_1"/>

For a server backend where all occurrences are stored in a list data type ([],array). (Python / Zope)

You can post in which ever order you like, you just need to try to get the value from the input with the checkbox type attribute. So the first index of the list if the checkbox was before the hidden element and the last index if the checkbox was after the hidden element.

For a server backend where all occurrences are concatenated with a comma (ASP.NET / IIS) You will need to (split/explode) the string by using a comma as a delimiter to create a list data type. ([])

Now you can attempt to grab the first index of the list if the checkbox was before the hidden element and grab the last index if the checkbox was after the hidden element.

You can run gdb with --args parameter,

gdb --args executablename arg1 arg2 arg3

If you want it to run automatically, place some commands in a file (e.g. 'run') and give it as argument: -x /tmp/cmds. Optionally you can run with -batch mode.

gdb -batch -x /tmp/cmds --args executablename arg1 arg2 arg3

The differences between Model() and Model.objects.create() are the following:

1. INSERT vs UPDATE

   Model.save() does either INSERT or UPDATE of an object in a DB, while Model.objects.create() does only INSERT.

   Model.save() does

   • UPDATE If the object’s primary key attribute is set to a value that evaluates to True

   • INSERT If the object’s primary key attribute is not set or if the UPDATE didn’t update anything (e.g. if primary key is set to a value that doesn’t exist in the database).

2. Existing primary key

   If primary key attribute is set to a value and such primary key already exists, then Model.save() performs UPDATE, but Model.objects.create() raises IntegrityError.

   Consider the following models.py:

   class Subject(models.Model):
      subject_id = models.PositiveIntegerField(primary_key=True, db_column='subject_id')
      name = models.CharField(max_length=255)
      max_marks = models.PositiveIntegerField()
   

   1. Insert/Update to db with Model.save()

      physics = Subject(subject_id=1, name='Physics', max_marks=100)
      physics.save()
      math = Subject(subject_id=1, name='Math', max_marks=50)  # Case of update
      math.save()
      

      Result:

      Subject.objects.all().values()
      <QuerySet [{'subject_id': 1, 'name': 'Math', 'max_marks': 50}]>
      

   2. Insert to db with Model.objects.create()

      Subject.objects.create(subject_id=1, name='Chemistry', max_marks=100)
      IntegrityError: UNIQUE constraint failed: m****t.subject_id
      

   Explanation: In the example, math.save() does an UPDATE (changes name from Physics to Math, and max_marks from 100 to 50), because subject_id is a primary key and subject_id=1 already exists in the DB. But Subject.objects.create() raises IntegrityError, because, again the primary key subject_id with the value 1 already exists.

3. Forced insert

   Model.save() can be made to behave as Model.objects.create() by using force_insert=True parameter: Model.save(force_insert=True).

4. Return value

   Model.save() return None where Model.objects.create() return model instance i.e. package_name.models.Model

Conclusion: Model.objects.create() does model initialization and performs save() with force_insert=True.

Excerpt from the source code of Model.objects.create()

def create(self, **kwargs):
    """
    Create a new object with the given kwargs, saving it to the database
    and returning the created object.
    """
    obj = self.model(**kwargs)
    self._for_write = True
    obj.save(force_insert=True, using=self.db)
    return obj

You could use a list comprehension:

def square(list):
    return [i ** 2 for i in list]

Or you could map it:

def square(list):
    return map(lambda x: x ** 2, list)

Or you could use a generator. It won't return a list, but you can still iterate through it, and since you don't have to allocate an entire new list, it is possibly more space-efficient than the other options:

def square(list):
    for i in list:
        yield i ** 2

Or you can do the boring old for-loop, though this is not as idiomatic as some Python programmers would prefer:

def square(list):
    ret = []
    for i in list:
        ret.append(i ** 2)
    return ret

You're looking for the cunningly named Registry.GetValue method.

Go to File > Preferences > Settings (or press Ctrl+,) then click the leftmost icon in the top right corner, "Open Settings (JSON)"

In the JSON settings window, add this (within the curly braces {}):

"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\bash.exe"`

(Here you can put any other custom settings you want as well)

Checkout that path to make sure your bash.exe file is there otherwise find out where it is and point to that path instead.

Now if you open a new terminal window in VS Code, it should open with bash instead of PowerShell.

I wanted a vanilla, lightweight (jQuery UI Layout weighs in at 185 KB), no dependency option (all existing libraries require jQuery), so I wrote Split.js.

It weights less than 2 KB and does not require any special markup. It supports older browsers back to Internet Explorer 9 (or Internet Explorer 8 with polyfills). For modern browsers, you can use it with Flexbox and grid layouts.

It looks like a container with the name qgis-desktop-2-4 already exists in the system. You can check the output of the below command to confirm if it indeed exists:

$ docker ps -a

The last column in the above command's output is for names.

If the container exists, remove it using:

$ docker rm qgis-desktop-2-4

Or forcefully using,

$ docker rm -f qgis-desktop-2-4

And then try creating a new container.

Just Add:

android:screenOrientation="portrait"

in "AndroidManifest.xml" :

<activity
android:screenOrientation="portrait"
android:name=".MainActivity"
android:label="@string/app_name">
</activity>

If you're using css modules this is what worked for me.

const [condition, setCondition] = useState(false);

\\ toggle condition

return (
  <span className={`${styles.always} ${(condition ? styles.sometimes : '')`}>
  </span>
)

DISCLAIMER: this answer is from Jul 2015 and uses Retrofit and OkHttp from that time.
Check this link for more info on Retrofit v2 and this one for the current OkHttp methods.

Okay, I got it working using Android Developers guide.

Just as OP, I'm trying to use Retrofit and OkHttp to connect to a self-signed SSL-enabled server.

Here's the code that got things working (I've removed the try/catch blocks):

public static RestAdapter createAdapter(Context context) {
  // loading CAs from an InputStream
  CertificateFactory cf = CertificateFactory.getInstance("X.509");
  InputStream cert = context.getResources().openRawResource(R.raw.my_cert);
  Certificate ca;
  try {
    ca = cf.generateCertificate(cert);
  } finally { cert.close(); }

  // creating a KeyStore containing our trusted CAs
  String keyStoreType = KeyStore.getDefaultType();
  KeyStore keyStore = KeyStore.getInstance(keyStoreType);
  keyStore.load(null, null);
  keyStore.setCertificateEntry("ca", ca);

  // creating a TrustManager that trusts the CAs in our KeyStore
  String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
  TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
  tmf.init(keyStore);

  // creating an SSLSocketFactory that uses our TrustManager
  SSLContext sslContext = SSLContext.getInstance("TLS");
  sslContext.init(null, tmf.getTrustManagers(), null);

  // creating an OkHttpClient that uses our SSLSocketFactory
  OkHttpClient okHttpClient = new OkHttpClient();
  okHttpClient.setSslSocketFactory(sslContext.getSocketFactory());

  // creating a RestAdapter that uses this custom client
  return new RestAdapter.Builder()
              .setEndpoint(UrlRepository.API_BASE)
              .setClient(new OkClient(okHttpClient))
              .build();
}

To help in debugging, I also added .setLogLevel(RestAdapter.LogLevel.FULL) to my RestAdapter creation commands and I could see it connecting and getting the response from the server.

All it took was my original .crt file saved in main/res/raw. The .crt file, aka the certificate, is one of the two files created when you create a certificate using openssl. Generally, it is a .crt or .cert file, while the other is a .key file.

Afaik, the .crt file is your public key and the .key file is your private key.

As I can see, you already have a .cert file, which is the same, so try to use it.

PS: For those that read it in the future and only have a .pem file, according to this answer, you only need this to convert one to the other:

openssl x509 -outform der -in your-cert.pem -out your-cert.crt

PS²: For those that don't have any file at all, you can use the following command (bash) to extract the public key (aka certificate) from any server:

echo -n | openssl s_client -connect your.server.com:443 | \
  sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/my_cert.crt

Just replace the your.server.com and the port (if it is not standard HTTPS) and choose a valid path for your output file to be created.

Perhaps a contrived "real world" example would help.

At my place of work we have rubbish bins that come in different flavours. All bins contain rubbish, but some bins are specialist and do not take all types of rubbish. So we have Bin<CupRubbish> and Bin<RecylcableRubbish>. The type system needs to make sure I can't put my HalfEatenSandwichRubbish into either of these types, but it can go into a general rubbish bin Bin<Rubbish>. If I wanted to talk about a Bin of Rubbish which may be specialised so I can't put in incompatible rubbish, then that would be Bin<? extends Rubbish>.

(Note: ? extends does not mean read-only. For instance, I can with proper precautions take out a piece of rubbish from a bin of unknown speciality and later put it back in a different place.)

Not sure how much that helps. Pointer-to-pointer in presence of polymorphism isn't entirely obvious.

I got this error when using a truststore which was exported using a IBM Websphere JDK keytool in #PKCS12 format and trying to communicate over SSL using that file on an Oracle JRE.

My solution was to run on an IBM JRE or convert the truststore to JKS using an IBM Websphere keytool, so I was able to run it in an Oracle JRE.

If you want an ANSI SQL-92 version:

select view_definition from information_schema.views where table_name = 'view_name';

you can use this for example

$array = json_decode($string,true)

but validate the Json before. You can validate from http://jsonviewer.stack.hu/

No, you cannot change package name unless you're okay with publishing it as a new app in Play Store:

Once you publish your application under its manifest package name, this is the unique identity of the application forever more. Switching to a different name results in an entirely new application, one that can’t be installed as an update to the existing application. Android manual confirms it as well here:

Caution: Once you publish your application, you cannot change the package name. The package name defines your application's identity, so if you change it, then it is considered to be a different application and users of the previous version cannot update to the new version. If you're okay with publishing new version of your app as a completely new entity, you can do it of course - just remove old app from Play Store (if you want) and publish new one, with different package name.

For me he problem was that my script was called pandas.py in the folder pandas which obviously messed up my imports.

Here is how to get the Guid's programmatically! You can then use these guids/filepaths with an above answer to add the reference!

Reference: http://www.vbaexpress.com/kb/getarticle.php?kb_id=278

Sub ListReferencePaths()
'Lists path and GUID (Globally Unique Identifier) for each referenced library.
'Select a reference in Tools > References, then run this code to get GUID etc.
    Dim rw As Long, ref
    With ThisWorkbook.Sheets(1)
        .Cells.Clear
        rw = 1
        .Range("A" & rw & ":D" & rw) = Array("Reference","Version","GUID","Path")
        For Each ref In ThisWorkbook.VBProject.References
            rw = rw + 1
            .Range("A" & rw & ":D" & rw) = Array(ref.Description, _
                   "v." & ref.Major & "." & ref.Minor, ref.GUID, ref.FullPath)
        Next ref
        .Range("A:D").Columns.AutoFit
    End With
End Sub

Here is the same code but printing to the terminal if you don't want to dedicate a worksheet to the output.

Sub ListReferencePaths() 
 'Macro purpose:  To determine full path and Globally Unique Identifier (GUID)
 'to each referenced library.  Select the reference in the Tools\References
 'window, then run this code to get the information on the reference's library

On Error Resume Next 
Dim i As Long 

Debug.Print "Reference name" & " | " & "Full path to reference" & " | " & "Reference GUID" 

For i = 1 To ThisWorkbook.VBProject.References.Count 
  With ThisWorkbook.VBProject.References(i) 
    Debug.Print .Name & " | " & .FullPath  & " | " & .GUID 
  End With 
Next i 
On Error GoTo 0 
End Sub 

Current date time to formated string:

Having the right CSS and JS libraries helps, this solved it for me

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.12.4.js"></script>
<script src="//code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

You can add the following in your .bashrc

if [ "$TERM" = xterm ]; then TERM=xterm-256color; fi

Sounds like you want to catch the DocumentCompleted event of your webbrowser control.

MSDN has a couple of good articles about the webbrowser control - WebBrowser Class has lots of examples, and How to: Add Web Browser Capabilities to a Windows Forms Application

I created an enhanced version, based on Trey Copland's fiddle, that I think is more like what you wanted. Added here for future reference to those who come here later. Fiddle example

    <body>
<style>
.modal {
  height: 390px;
  border: 5px solid green;

  overflow:auto;
  border: 5px solid red;
}
.scrollable {
  height: 1200px;
  border: 5px solid yellow;

}
.footer {
  height: 2em;
  padding: .5em;
}
</style>
      <div class="modal">

The div doesn't take up all the available horizontal space when absolutely positioned. Explicitly setting the width to 100% will solve the problem:

HTML

<div id="my-div">I want to be centered</div>?

CSS

#my-div {
   position: absolute;
   bottom: 15px;
   text-align: center;
   width: 100%;
}

?

Don't forget to add the

CONFIG += console 

flag in the qmake .pro file.

For the rest is just using some of Qt classes. One way I use it is to spawn processes cross-platform.

My solution is to add the following code to the cellForRowAtIndexPath event:

UIView *solidColor = [cell viewWithTag:100];
if (!solidColor) {

    solidColor = [[UIView alloc] initWithFrame:cell.bounds];
    solidColor.tag = 100; //Big tag to access the view afterwards
    [cell addSubview:solidColor];
    [cell sendSubviewToBack:solidColor];
    [solidColor release];
}
solidColor.backgroundColor = [UIColor colorWithRed:254.0/255.0
                                             green:233.0/255.0
                                              blue:233.0/255.0
                                             alpha:1.0];

Works under any circumstances, even with disclosure buttons, and is better for your logic to act on cells color state in cellForRowAtIndexPath than in cellWillShow event I think.

Jon really gave a nice solution, I didn't know you could do that!

At times what I resorted to was inheriting from the class and creating its constructors. E.g.

public class FooList : List<Foo> { ... }

Not the best solution (unless your assembly gets used by other people), but it works.

LD_LIBRARY_PATH is the default library path which is accessed to check for available dynamic and shared libraries. It is specific to linux distributions.

It is similar to environment variable PATH in windows that linker checks for possible implementations during linking time.

This usually happens for me if I compiled the project in Visual Studio 2017 & then I try to rebuild & run it with .NET Core with the command line command "dotnet run".

Simply deleting all the "bin" & "obj" folders - both inside "ClientApp" & directly in the project folder - allowed the .NET Core command "dotnet run" to rebuild & run successfully.

For those who do not have 4.5, Here is my library function that reads json. It requires a project reference to System.Web.Extensions.

using System.Web.Script.Serialization;

public object DeserializeJson<T>(string Json)
{
    JavaScriptSerializer JavaScriptSerializer = new JavaScriptSerializer();
    return JavaScriptSerializer.Deserialize<T>(Json);
}

Usually, json is written out based on a contract. That contract can and usually will be codified in a class (T). Sometimes you can take a word from the json and search the object browser to find that type.

Example usage:

Given the json

{"logEntries":[],"value":"My Code","text":"My Text","enabled":true,"checkedIndices":[],"checkedItemsTextOverflows":false}

You could parse it into a RadComboBoxClientState object like this:

string ClientStateJson = Page.Request.Form("ReportGrid1_cboReportType_ClientState");
RadComboBoxClientState RadComboBoxClientState = DeserializeJson<RadComboBoxClientState>(ClientStateJson);
return RadComboBoxClientState.Value;

I followed around five different answers as well as all the blog posts in the previous answers and still had problems. I was trying to add a listener to some existing code that was tracing using the TraceSource.TraceEvent(TraceEventType, Int32, String) method where the TraceSource object was initialised with a string making it a 'named source'.

For me the issue was not creating a valid combination of source and switch elements to target this source. Here is an example that will log to a file called tracelog.txt. For the following code:

TraceSource source = new TraceSource("sourceName");
source.TraceEvent(TraceEventType.Verbose, 1, "Trace message");

I successfully managed to log with the following diagnostics configuration:

<system.diagnostics>
    <sources>
        <source name="sourceName" switchName="switchName">
            <listeners>
                <add
                    name="textWriterTraceListener"
                    type="System.Diagnostics.TextWriterTraceListener"
                    initializeData="tracelog.txt" />
            </listeners>
        </source>
    </sources>

    <switches>
        <add name="switchName" value="Verbose" />
    </switches>
</system.diagnostics>

I use a version of a script based on Stephen Haberman's answer:

if [ -n "$1" ]; then
    gitbin="git -C $1"
else
    gitbin="git"
fi

# Fetches from all the remotes, although --all can be replaced with origin
$gitbin fetch --all
if [ $($gitbin rev-parse HEAD) != $($gitbin rev-parse @{u}) ]; then
    $gitbin rebase @{u} --preserve-merges
fi

Assuming this script is called git-fetch-and-rebase, it can be invoked with an optional argument directory name of the local Git repository to perform operation on. If the script is called with no arguments, it assumes the current directory to be part of the Git repository.

Examples:

# Operates on /abc/def/my-git-repo-dir
git-fetch-and-rebase /abc/def/my-git-repo-dir

# Operates on the Git repository which the current working directory is part of
git-fetch-and-rebase

It is available here as well.

Similar to some of the solutions posted, but in my case I did the status bar transparent and fix the position of the action bar with some negative margin

if (Build.VERSION.SDK_INT >= 21) {
    getWindow().setStatusBarColor(Color.TRANSPARENT);
    FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) toolbar.getLayoutParams();
    lp.setMargins(0, -getStatusBarHeight(), 0, 0);
}

And I used in the toolbar and the root view

android:fitsSystemWindows="true"

Here's a simple example to demonstrate Map usage:

Map<String, String> map = new HashMap<String, String>();
map.put("Color1","Red");
map.put("Color2","Blue");
map.put("Color3","Green");
map.put("Color4","White");

System.out.println(map);
// {Color4=White, Color3=Green, Color1=Red, Color2=Blue}        

System.out.println(map.get("Color2")); // Blue

System.out.println(map.keySet());
// [Color4, Color3, Color1, Color2]

for (Map.Entry<String,String> entry : map.entrySet()) {
    System.out.printf("%s -> %s%n", entry.getKey(), entry.getValue());
}
// Color4 -> White
// Color3 -> Green
// Color1 -> Red
// Color2 -> Blue

Note that the entries are iterated in arbitrary order. If you need a specific order, then you may consider e.g. LinkedHashMap

This is now possible with PHP 5.6.x, using the ... operator (also known as splat operator in some languages):

Example:

function addDateIntervalsToDateTime( DateTime $dt, DateInterval ...$intervals )
{
    foreach ( $intervals as $interval ) {
        $dt->add( $interval );
    }
    return $dt;
}

addDateIntervaslToDateTime( new DateTime, new DateInterval( 'P1D' ), 
        new DateInterval( 'P4D' ), new DateInterval( 'P10D' ) );

    str+="bottomFromBottom: "+bottomFromBottom+"<br>";
    str+="rightFromRight: "+rightFromRight+"<br>";
    link.html(str);

The result are

When the document is scrollable, $(window).height() returns height of browser viewport, not the width of document of which some parts are hiden in scroll. See http://api.jquery.com/height/ .
