Yes, there is awesome simple bash script I found, which allows you to update the Postman Linux app, straight from the terminal, called postman-updater-linux.

Just install it using NPM:

npm install -g postman-updater-linux

Then check for updates:

sudo postman-updater check

Then install:

sudo postman-updater install

Or update:

sudo postman-updater update

All three last commands can be used with custom location by adding -l /your/custom/path to end of this command.

It is possible to upack without node installed using the following 7-Zip plugin:

Thanks @MayaPosch for mentioning that in this comment.

you can fix this problem with style like this.

In my case, the installation of nlme package is in trouble:

mv: cannot move '/home/guanshim/R/x86_64-pc-linux-gnu-library/3.4/nlme' 
to '/home/guanshim/R/x86_64-pc-linux-gnu-library/3.4/00LOCK-nlme/nlme':

For Windows, you can also whitelist your extension through Windows policies. The full steps are details in this answer, but there are quicker steps:

1. Create the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\ExtensionInstallWhitelist.
2. For each extension you want to whitelist, add a string value whose name should be a sequence number (starting at 1) and value is the extension ID.

For instance, in order to whitelist 2 extensions with ID aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa and bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb, create a string value with name 1 and value aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa, and a second value with name 2 and value bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb. This can be sum up by this registry file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\ExtensionInstallWhitelist]
"1"="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
"2"="bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb"

EDIT: actually, Chromium docs also indicate how to do it for other OS.

The Back button wasn't working for me as well, but I figured out that the problem was that I had html content inside my main page, in the ui-view element.

i.e.

<div ui-view>
     <h1> Hey Kids! </h1>
     <!-- More content -->
</div>

So I moved the content into a new .html file, and marked it as a template in the .js file with the routes.

i.e.

   .state("parent.mystuff", {
        url: "/mystuff",
        controller: 'myStuffCtrl',
        templateUrl: "myStuff.html"
    })

Even if you have enabled the Virtualization(VT) in BIOS settings, some antivirus options prevent HAXM installation.

For example: In Avast antivirus under Settings (parametres) tab > Troubleshooting (depannage), you should uncheck "Enable Hardware-assisted Virtualization" ("activer l'assistance a la virtualisation").

Now restart your computer and re-install the Intel's HAXM which can be found under ~SDK_LOCATION\extras\intel\Hardware_Accelerated_Execution_Manager. You can also manually download the standalone HAXM installer from Intel's website.

I'm on windows and had the same issue.

I used the below code :

install.packages("devtools", type = "win.binary")

Then library(devtools) worked for me.

As per bash - The Set Builtin manual, if -e/errexit is set, the shell exits immediately if a pipeline consisting of a single simple command, a list or a compound command returns a non-zero status.

By default, the exit status of a pipeline is the exit status of the last command in the pipeline, unless the pipefail option is enabled (it's disabled by default).

If so, the pipeline's return status of the last (rightmost) command to exit with a non-zero status, or zero if all commands exit successfully.

If you'd like to execute something on exit, try defining trap, for example:

trap onexit EXIT

where onexit is your function to do something on exit, like below which is printing the simple stack trace:

onexit(){ while caller $((n++)); do :; done; }

There is similar option -E/errtrace which would trap on ERR instead, e.g.:

trap onerr ERR

Examples

Zero status example:

$ true; echo $?
0

Non-zero status example:

$ false; echo $?
1

Negating status examples:

$ ! false; echo $?
0
$ false || true; echo $?
0

Test with pipefail being disabled:

$ bash -c 'set +o pipefail -e; true | true | true; echo success'; echo $?
success
0
$ bash -c 'set +o pipefail -e; false | false | true; echo success'; echo $?
success
0
$ bash -c 'set +o pipefail -e; true | true | false; echo success'; echo $?
1

Test with pipefail being enabled:

$ bash -c 'set -o pipefail -e; true | false | true; echo success'; echo $?
1

The universal adb driver installer worked for me. I went from an HTC to a Samsung to a LG Nexus. The drivers are all over the place for me.

http://adbdriver.com/

When you run

install.packages("whatever")

you got message that your binaries are downloaded into temporary location (e.g. The downloaded binary packages are in C:\Users\User_name\AppData\Local\Temp\RtmpC6Y8Yv\downloaded_packages ). Go there. Take binaries (zip file). Copy paste into location which you get from running the code:

.libPaths()

If libPaths shows 2 locations, then paste into second one. Load library:

library(whatever)

Fixed.

Remove the index and do reset

rm -f .git/index
git reset

Before answering, I would like to give you some data from Wiki

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding.

When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system). Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory.

To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

gcc provides functionality to disable structure padding. i.e to avoid these meaningless bytes in some cases. Consider the following structure:

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}sSampleStruct;

sizeof(sSampleStruct) will be 12 rather than 8. Because of structure padding. By default, In X86, structures will be padded to 4-byte alignment:

typedef struct
{
     char Data1;
     //3-Bytes Added here.
     int Data2;
     unsigned short Data3;
     char Data4;
     //1-byte Added here.

}sSampleStruct;

We can use __attribute__((packed, aligned(X))) to insist particular(X) sized padding. X should be powers of two. Refer here

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}__attribute__((packed, aligned(1))) sSampleStruct;  

so the above specified gcc attribute does not allow the structure padding. so the size will be 8 bytes.

If you wish to do the same for all the structures, simply we can push the alignment value to stack using #pragma

#pragma pack(push, 1)

//Structure 1
......

//Structure 2
......

#pragma pack(pop)

Using this attribute is definitely unsafe.

One particular thing it breaks is the ability of a union which contains two or more structs to write one member and read another if the structs have a common initial sequence of members. Section 6.5.2.3 of the C11 standard states:

6 One special guarantee is made in order to simplify the use of unions: if a union contains several structures that share a common initial sequence (see below), and if the union object currently contains one of these structures, it is permitted to inspect the common initial part of any of them anywhere that a declaration of the completed type of the union is visible. Tw o structures share a common initial sequence if corresponding members have compatible types (and, for bit-fields, the same widths) for a sequence of one or more initial members.

...

9 EXAMPLE 3 The following is a valid fragment:

union {
    struct {
        int    alltypes;
    }n;
    struct {
        int    type;
        int    intnode;
    } ni;
    struct {
        int    type;
        double doublenode;
    } nf;
}u;
u.nf.type = 1;
u.nf.doublenode = 3.14;
/*
...
*/
if (u.n.alltypes == 1)
if (sin(u.nf.doublenode) == 0.0)
/*
...
*/

When __attribute__((packed)) is introduced it breaks this. The following example was run on Ubuntu 16.04 x64 using gcc 5.4.0 with optimizations disabled:

#include <stdio.h>
#include <stdlib.h>

struct s1
{
    short a;
    int b;
} __attribute__((packed));

struct s2
{
    short a;
    int b;
};

union su {
    struct s1 x;
    struct s2 y;
};

int main()
{
    union su s;
    s.x.a = 0x1234;
    s.x.b = 0x56789abc;

    printf("sizeof s1 = %zu, sizeof s2 = %zu\n", sizeof(struct s1), sizeof(struct s2));
    printf("s.y.a=%hx, s.y.b=%x\n", s.y.a, s.y.b);
    return 0;
}

Output:

sizeof s1 = 6, sizeof s2 = 8
s.y.a=1234, s.y.b=5678

Even though struct s1 and struct s2 have a "common initial sequence", the packing applied to the former means that the corresponding members don't live at the same byte offset. The result is the value written to member x.b is not the same as the value read from member y.b, even though the standard says they should be the same.

This blog can help you. The trick is to use SpEL (spring expression language) to read the system properties like user.home, to read user home directory using SpEL you could use
#{ systemProperties['user.home']} expression inside your bean elements. For example to access your properties file stored in your home directory you could use the following in your PropertyPlaceholderConfigurer, it worked for me.

 <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <value>file:#{ systemProperties['user.home']}/ur_folder/settings.properties</value>
    </property>
</bean>

The last question has an easy answer:

[1] 8

Meaning I am running R64. If I were running 32 bit R it would return 4. Just because you are running a 64 bit OS does not mean you will be running 64 bit R, and from the error message it appears you are not.

EDIT: If the package has binaries, then they are in separate directories. The specifics will depend on the OS. Notice that your LoadLibrary error occurred when it attempted to find the dll in ...rJava/libs/x64/... On my MacOS system the ...rJava/libs/...` folder has 3 subdirectories: i386, ppc, and x86_64. (The ppc files are obviously useless baggage.)

Structure packing is only done when you tell your compiler explicitly to pack the structure. Padding is what you're seeing. Your 32-bit system is padding each field to word alignment. If you had told your compiler to pack the structures, they'd be 6 and 5 bytes, respectively. Don't do that though. It's not portable and makes compilers generate much slower (and sometimes even buggy) code.

What classes are missing? The class name itself should be a good clue to the missing module.

FYI, I know its really convenient to include the uber spring jar but this really causes issues when integrating with other projects. One of the benefits behind the dependency system is that it will resolve version conflicts among the dependencies.

If my library depends on spring-core:2.5 and you depend on my library and uber-spring:3.0, you now have 2 versions of spring on your classpath.

You can get around this with exclusions but its much easier to list the dependencies correctly and not have to worry about it.

Combined with others code and created a view:

SELECT
     n.nspname  as "schema"
    ,t.relname  as "table"
    ,c.relname  as "index"
    ,pg_get_indexdef(indexrelid) as "def"
FROM pg_catalog.pg_class c
    JOIN pg_catalog.pg_namespace n ON n.oid        = c.relnamespace
    JOIN pg_catalog.pg_index i ON i.indexrelid = c.oid
    JOIN pg_catalog.pg_class t ON i.indrelid   = t.oid
WHERE c.relkind = 'i'

Take a look at Serialization, a technique to "convert" an entire object to a byte stream. You may send it to the network or write it into a file and then restore it back to an object later.

The best place for it is just before you need it and no sooner.

Also, depending on your users' physical location, using a service like Amazon's S3 service may help users download it from a server physically closer to them than your server.

Is your js script a commonly used lib like jQuery or prototype? If so, there are a number of companies, like Google and Yahoo, that have tools to provide these files for you on a distributed network.

You've answered the question with this statement:

Cron calls this .sh every 2 minutes

Cron does not run in a terminal, so why would you expect one to be set?

The most common reason for getting this error message is because the script attempts to source the user's .profile which does not check that it's running in a terminal before doing something tty related. Workarounds include using a shebang line like:

#!/bin/bash -p

Which causes the sourcing of system-level profile scripts which (one hopes) does not attempt to do anything too silly and will have guards around code that depends on being run from a terminal.

If this is the entirety of the script, then the TERM error is coming from something other than the plain content of the script.

Although often we are used to seeing objects with public properties without any access control, JavaScript allows us to accurately describe properties. In fact, we can use descriptors in order to control how a property can be accessed and which logic we can apply to it. Consider the following example:

var employee = {
    first: "Boris",
    last: "Sergeev",
    get fullName() {
        return this.first + " " + this.last;
    },
    set fullName(value) {
        var parts = value.toString().split(" ");
        this.first = parts[0] || "";
        this.last = parts[1] || "";
    },
    email: "[email protected]"
};

The final result:

console.log(employee.fullName); //Boris Sergeev
employee.fullName = "Alex Makarenko";

console.log(employee.first);//Alex
console.log(employee.last);//Makarenko
console.log(employee.fullName);//Alex Makarenko

System.Net.WebException: The remote server returned an error: (411) Length Required.

This is a pretty common issue that comes up when trying to make call a REST based API method through POST. Luckily, there is a simple fix for this one.

This is the code I was using to call the Windows Azure Management API. This particular API call requires the request method to be set as POST, however there is no information that needs to be sent to the server.

var request = (HttpWebRequest) HttpWebRequest.Create(requestUri);
request.Headers.Add("x-ms-version", "2012-08-01"); request.Method =
"POST"; request.ContentType = "application/xml";

To fix this error, add an explicit content length to your request before making the API call.

request.ContentLength = 0;

You can use:

SELECT SUBDATE(NOW(), 1);

or

SELECT SUBDATE(NOW(), INTERVAL 1 DAY);

or

SELECT NOW() - INTERVAL 1 DAY;

or

SELECT DATE_SUB(NOW(), INTERVAL 1 DAY);

If you are having trouble with Eclipse 2019 and using a dark theme and setting the background and having it not change: There seems to be a recent Eclipse bug. I suggest you look here or here for workarounds.

If you really want an iterator-free solution, you can use numpy and its array round function.

import numpy as np
myList = list(np.around(np.array(myList),2))

What you are going to read is rather hacky, so don't try this at home!

In SQL in general the answer to your question is NO, but because of the relaxed mode of the GROUP BY (mentioned by @bluefeet), the answer is YES in MySQL.

Suppose, you have a BTREE index on (post_status, post_type, post_author, post_date). How does the index look like under the hood?

(post_status='publish', post_type='post', post_author='user A', post_date='2012-12-01') (post_status='publish', post_type='post', post_author='user A', post_date='2012-12-31') (post_status='publish', post_type='post', post_author='user B', post_date='2012-10-01') (post_status='publish', post_type='post', post_author='user B', post_date='2012-12-01')

That is data is sorted by all those fields in ascending order.

When you are doing a GROUP BY by default it sorts data by the grouping field (post_author, in our case; post_status, post_type are required by the WHERE clause) and if there is a matching index, it takes data for each first record in ascending order. That is the query will fetch the following (the first post for each user):

(post_status='publish', post_type='post', post_author='user A', post_date='2012-12-01') (post_status='publish', post_type='post', post_author='user B', post_date='2012-10-01')

But GROUP BY in MySQL allows you to specify the order explicitly. And when you request post_user in descending order, it will walk through our index in the opposite order, still taking the first record for each group which is actually last.

That is

...
WHERE wp_posts.post_status='publish' AND wp_posts.post_type='post'
GROUP BY wp_posts.post_author DESC

will give us

(post_status='publish', post_type='post', post_author='user B', post_date='2012-12-01') (post_status='publish', post_type='post', post_author='user A', post_date='2012-12-31')

Now, when you order the results of the grouping by post_date, you get the data you wanted.

SELECT wp_posts.*
FROM wp_posts
WHERE wp_posts.post_status='publish' AND wp_posts.post_type='post'
GROUP BY wp_posts.post_author DESC
ORDER BY wp_posts.post_date DESC;

NB:

This is not what I would recommend for this particular query. In this case, I would use a slightly modified version of what @bluefeet suggests. But this technique might be very useful. Take a look at my answer here: Retrieving the last record in each group

Pitfalls: The disadvantages of the approach is that

• the result of the query depends on the index, which is against the spirit of the SQL (indexes should only speed up queries);
• index does not know anything about its influence on the query (you or someone else in future might find the index too resource-consuming and change it somehow, breaking the query results, not only its performance)
• if you do not understand how the query works, most probably you'll forget the explanation in a month and the query will confuse you and your colleagues.

The advantage is performance in hard cases. In this case, the performance of the query should be the same as in @bluefeet's query, because of amount of data involved in sorting (all data is loaded into a temporary table and then sorted; btw, his query requires the (post_status, post_type, post_author, post_date) index as well).

What I would suggest:

As I said, those queries make MySQL waste time sorting potentially huge amounts of data in a temporary table. In case you need paging (that is LIMIT is involved) most of the data is even thrown off. What I would do is minimize the amount of sorted data: that is sort and limit a minimum of data in the subquery and then join back to the whole table.

SELECT * 
FROM wp_posts
INNER JOIN
(
  SELECT max(post_date) post_date, post_author
  FROM wp_posts
  WHERE post_status='publish' AND post_type='post'
  GROUP BY post_author
  ORDER BY post_date DESC
  -- LIMIT GOES HERE
) p2 USING (post_author, post_date)
WHERE post_status='publish' AND post_type='post';

The same query using the approach described above:

SELECT *
FROM (
  SELECT post_id
  FROM wp_posts
  WHERE post_status='publish' AND post_type='post'
  GROUP BY post_author DESC
  ORDER BY post_date DESC
  -- LIMIT GOES HERE
) as ids
JOIN wp_posts USING (post_id);

All those queries with their execution plans on SQLFiddle.

    let strTimeStamp: String = "\(milliseconds)"
    return strTimeStamp
}

To use

let now = NSDate()
let nowTimeStamp = self.getCurrentTimeStampWOMiliseconds(dateToConvert: now)

There is a visual studio extension Automatic Versions which supports Visual Studio (2012, 2013, 2015) 2017 & 2019.

Screen Shots

Maybe not the most efficient way. But you could convert the list into a vector.

#include <list>
#include <vector>

list<Object> myList;

vector<Object> myVector(myList.begin(), myList.end());

Then access the vector using the [x] operator.

auto x = MyVector[0];

You could put that in a helper function:

#include <memory>
#include <vector>
#include <list>

template<class T>
shared_ptr<vector<T>> 
ListToVector(list<T> List) {
shared_ptr<vector<T>> Vector {
        new vector<string>(List.begin(), List.end()) }
return Vector;
}

Then use the helper funciton like this:

auto MyVector = ListToVector(Object);
auto x = MyVector[0];

Try this,

[textField setDelegate: self];

Then, in textField delegate method

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    return YES;
}

Unfortunately, the tool mentioned above is blocked by several antivirus vendors. If this is the case for you then take a look at the following.

Open the non-exportable cert in the cert store and locate the Thumbprint value.

Next, open regedit to the path below and locate the registry key matching the thumbprint value.

An export of the registry key will contain the complete certificate including the private key. Once exported, copy the export to the other server and import it into the registry.

The cert will appear in the certificate manager with the private key included.

Machine Store: HKLM\SOFTWARE\Microsoft\SystemCertificates\MY\Certificates User Store: HKCU\SOFTWARE\Microsoft\SystemCertificates\MY\Certificates

In a pinch, you could save the export as a backup of the certificate.

I think this way also a normal way. But sorry, I can't describe in English ((

One of the best way to list indices + to display its status together with list : is by simply executing below query.

Note: preferably use Sense to get the proper output.

curl -XGET 'http://localhost:9200/_cat/shards'

The sample output is as below. The main advantage is, it basically shows index name and the shards it saved into, index size and shards ip etc

index1     0 p STARTED     173650  457.1mb 192.168.0.1 ip-192.168.0.1 
index1     0 r UNASSIGNED                                                 
index2     1 p STARTED     173435  456.6mb 192.168.0.1 ip-192.168.0.1

This did not work for me. I moved a repo from (e.g.) c:\project1\ to c:\repo\project1\ and Git for windows does not show any changes.

git status shows an error because one of the submodules "is not a git repository" and shows the old path. e.g. (names changed to protect IP)

fatal: Not a git repository: C:/project1/.git/modules/subproject/subproject2 fatal: 'git status --porcelain' failed in submodule subproject

I had to manually edit the .git files in the submodules to point to the correct relative path to the submodule's repo (in the main repo's .git/modules directory)

Just try this. It's easy without any extra builtin functions.

#include <iostream>

int prime(int n,int r){

  for(int i=2;n<=r;i++){
    if(i==2 || i==3 || i==5 || i==7){
      std::cout<<i<<" ";
      n++;
    } else if(i%2==0 || i%3==0 || i%5==0 || i%7==0)
      continue;
    else {
      std::cout<<i<<" ";
      n++;
    }
  }

}

main(){

  prime(1,25);
}

Testing by 2,3,5,7 is good enough for up to 120, so 100 is OK.

There are 25 primes below 100, an 30 below 121 = 11*11.

This exception could point to the LINQ parameter that is named source:

 System.Linq.Enumerable.Select[TSource,TResult](IEnumerable`1 source, Func`2 selector)

As the source parameter in your LINQ query (var nCounts = from sale in sal) is 'sal', I suppose the list named 'sal' might be null.

I believe you are looking for -maxdepth 1.

Here is my experience with Jenkins version 1.636: as long as I have only one "Install automatically" JDK configured in Jenkins JDK section, I don't see "JDK" dropdown in Job=>Configure section, but as soon as I added second JDK in Jenkins config, JDK dropdown appeared in Job=>Configure section with 3 options [(System), JDK1, JDK2]

This is a really quick & detailed solution

Open the Terminal and execute the following to get the latest stable version:

sudo gem install cocoapods

Add --pre to get the latest pre release:

sudo gem install cocoapods --pre

Incase any error occured

Try uninstall and install again:

sudo gem uninstall cocoapods
sudo gem install cocoapods

Run after updating CocoaPods

sudo gem clean cocoapods

After updating CocoaPods, also need to update Podfile.lock file in your project.

Go to your project directory

pod install

Use css text-transform to display text in all input type text. In Jquery you can then transform the value to uppercase on blur event.

Css:

input[type=text] {
    text-transform: uppercase;
}

Jquery:

$(document).on('blur', "input[type=text]", function () {
    $(this).val(function (_, val) {
        return val.toUpperCase();
    });
});

Try this:

delete from your_table;    
delete from sqlite_sequence where name='your_table';

SQLite Autoincrement

SQLite keeps track of the largest ROWID that a table has ever held using the special SQLITE_SEQUENCE table. The SQLITE_SEQUENCE table is created and initialized automatically whenever a normal table that contains an AUTOINCREMENT column is created. The content of the SQLITE_SEQUENCE table can be modified using ordinary UPDATE, INSERT, and DELETE statements. But making modifications to this table will likely perturb the AUTOINCREMENT key generation algorithm. Make sure you know what you are doing before you undertake such changes.

JavaScript's Date object supports the ISO date format, so as long as you have access to the date string, you can do something like this:

> foo = new Date("2012-07-14T01:00:00+01:00")
Sat, 14 Jul 2012 00:00:00 GMT
> foo.toTimeString()
'17:00:00 GMT-0700 (MST)'

If you want the time string without the seconds and the time zone then you can call the getHours() and getMinutes() methods on the Date object and format the time yourself.

No external libraries, works on both Python 2.7 and 3.x:

>>> list(set({"a":1, "b": 2}.values()))[0]
1

For aribtrary key just leave out .values()

>>> list(set({"a":1, "b": 2}))[0]
'a'

After updating to OS X 10.9.2, I started having invalid SSL certificate issues with Homebrew, Textmate, RVM, and Github.

When I initiate a brew update, I was getting the following error:

fatal: unable to access 'https://github.com/Homebrew/homebrew/': SSL certificate problem: Invalid certificate chain
Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master

I was able to alleviate some of the issue by just disabling the SSL verification in Git. From the console (a.k.a. shell or terminal):

git config --global http.sslVerify false

I am leary to recommend this because it defeats the purpose of SSL, but it is the only advice I've found that works in a pinch.

I tried rvm osx-ssl-certs update all which stated Already are up to date.

In Safari, I visited https://github.com and attempted to set the certificate manually, but Safari did not present the options to trust the certificate.

Ultimately, I had to Reset Safari (Safari->Reset Safari... menu). Then afterward visit github.com and select the certificate, and "Always trust" This feels wrong and deletes the history and stored passwords, but it resolved my SSL verification issues. A bittersweet victory.

Now I need to connect that application from my local computer, but I don't know the JMX port number of the remote computer. Where can I find it? Or, must I restart that application with some VM parameters to specify the port number?

By default JMX does not publish on a port unless you specify the arguments from this page: How to activate JMX...

-Dcom.sun.management.jmxremote # no longer required for JDK6
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false # careful with security implications
-Dcom.sun.management.jmxremote.authenticate=false # careful with security implications

If you are running you should be able to access any of those system properties to see if they have been set:

if (System.getProperty("com.sun.management.jmxremote") == null) {
    System.out.println("JMX remote is disabled");
} else [
    String portString = System.getProperty("com.sun.management.jmxremote.port");
    if (portString != null) {
        System.out.println("JMX running on port "
            + Integer.parseInt(portString));
    }
}

Depending on how the server is connected, you might also have to specify the following parameter. As part of the initial JMX connection, jconsole connects up to the RMI port to determine which port the JMX server is running on. When you initially start up a JMX enabled application, it looks its own hostname to determine what address to return in that initial RMI transaction. If your hostname is not in /etc/hosts or if it is set to an incorrect interface address then you can override it with the following:

-Djava.rmi.server.hostname=<IP address>

As an aside, my SimpleJMX package allows you to define both the JMX server and the RMI port or set them both to the same port. The above port defined with com.sun.management.jmxremote.port is actually the RMI port. This tells the client what port the JMX server is running on.

It's actually very similar to jQuery:

document.getElementsByClassName('class1 class2')

MDN Doc getElementsByClassName

Activity involved is completely unaware of the DialogFragment.

Fragment class:

public class MyFragment extends Fragment {
int mStackLevel = 0;

    super.onCreate(savedInstanceState);

    if (savedInstanceState != null) {
        mStackLevel = savedInstanceState.getInt("level");
    }
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("level", mStackLevel);
}

void showDialog(int type) {

    mStackLevel++;

    FragmentTransaction ft = getActivity().getFragmentManager().beginTransaction();
    Fragment prev = getActivity().getFragmentManager().findFragmentByTag("dialog");
    if (prev != null) {
        ft.remove(prev);
    }
    ft.addToBackStack(null);

    switch (type) {

        case DIALOG_FRAGMENT:

            DialogFragment dialogFrag = MyDialogFragment.newInstance(123);
            dialogFrag.setTargetFragment(this, DIALOG_FRAGMENT);
            dialogFrag.show(getFragmentManager().beginTransaction(), "dialog");

            break;
    }
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch(requestCode) {
            case DIALOG_FRAGMENT:

                if (resultCode == Activity.RESULT_OK) {
                    // After Ok code.
                } else if (resultCode == Activity.RESULT_CANCELED){
                    // After Cancel code.
                }

                break;
        }
    }
}

}

DialogFragment class:

public static MyDialogFragment newInstance(int num){

    MyDialogFragment dialogFragment = new MyDialogFragment();
    Bundle bundle = new Bundle();
    bundle.putInt("num", num);
    dialogFragment.setArguments(bundle);

    return dialogFragment;

}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    return new AlertDialog.Builder(getActivity())
            .setTitle(R.string.ERROR)
            .setIcon(android.R.drawable.ic_dialog_alert)
            .setPositiveButton(R.string.ok_button,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int whichButton) {
                            getTargetFragment().onActivityResult(getTargetRequestCode(), Activity.RESULT_OK, getActivity().getIntent());
                        }
                    }
            )
            .setNegativeButton(R.string.cancel_button, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                    getTargetFragment().onActivityResult(getTargetRequestCode(), Activity.RESULT_CANCELED, getActivity().getIntent());
                }
            })
            .create();
}
}

To elaborate some more on this, adding

script-src 'self' http://somedomain 'unsafe-inline' 'unsafe-eval';

to the meta tag like so,

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; script-src 'self' https://somedomain.com/ 'unsafe-inline' 'unsafe-eval';  media-src *">

fixes the error.

I you are using Visual Studio 2012, download and install Update 2 that Microsoft released recently (as of 4/2013).

Visual Studio 2012 Update 2

There are some bug fixes in that update related to the issue.

Below is a fully functional example of what I believe you're trying to do (with a functional snippet).

Explanation

Based on your question, you seem to be modifying 1 property in state for all of your elements. That's why when you click on one, all of them are being changed.

In particular, notice that the state tracks an index of which element is active. When MyClickable is clicked, it tells the Container its index, Container updates the state, and subsequently the isActive property of the appropriate MyClickables.

Example

class Container extends React.Component {_x000D_
  state = {_x000D_
    activeIndex: null_x000D_
  }_x000D_
_x000D_
  handleClick = (index) => this.setState({ activeIndex: index })_x000D_
_x000D_
  render() {_x000D_
    return <div>_x000D_
      <MyClickable name="a" index={0} isActive={ this.state.activeIndex===0 } onClick={ this.handleClick } />_x000D_
      <MyClickable name="b" index={1} isActive={ this.state.activeIndex===1 } onClick={ this.handleClick }/>_x000D_
      <MyClickable name="c" index={2} isActive={ this.state.activeIndex===2 } onClick={ this.handleClick }/>_x000D_
    </div>_x000D_
  }_x000D_
}_x000D_
_x000D_
class MyClickable extends React.Component {_x000D_
  handleClick = () => this.props.onClick(this.props.index)_x000D_
  _x000D_
  render() {_x000D_
    return <button_x000D_
      type='button'_x000D_
      className={_x000D_
        this.props.isActive ? 'active' : 'album'_x000D_
      }_x000D_
      onClick={ this.handleClick }_x000D_
    >_x000D_
      <span>{ this.props.name }</span>_x000D_
    </button>_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Container />, document.getElementById('app'))

button {_x000D_
  display: block;_x000D_
  margin-bottom: 1em;_x000D_
}_x000D_
_x000D_
.album>span:after {_x000D_
  content: ' (an album)';_x000D_
}_x000D_
_x000D_
.active {_x000D_
  font-weight: bold;_x000D_
}_x000D_
_x000D_
.active>span:after {_x000D_
  content: ' ACTIVE';_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react-dom.min.js"></script>_x000D_
<div id="app"></div>

Update: "Loops"

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.

// New render method for `Container`
render() {
  const clickables = [
    { name: "a" },
    { name: "b" },
    { name: "c" },
  ]

  return <div>
      { clickables.map(function(clickable, i) {
          return <MyClickable key={ clickable.name }
            name={ clickable.name }
            index={ i }
            isActive={ this.state.activeIndex === i }
            onClick={ this.handleClick }
          />
        } )
      }
  </div>
}

Adding to the answers above, for those who want a quick way to use an external USB device (HDD, flash drive) working inside docker, and not using priviledged mode:

Find the devpath to your device on the host:

sudo fdisk -l

You can recognize your drive by it's capacity quite easily from the list. Copy this path (for the following example it is /dev/sda2).

Disque /dev/sda2 : 554,5 Go, 57151488 octets, 111624 secteurs
Unités : secteur de 1 × 512 = 512 octets
Taille de secteur (logique / physique) : 512 octets / 512 octets
taille d'E/S (minimale / optimale) : 512 octets / 512 octets

Mount this devpath (preferable to /media):

sudo mount <drive path> /media/<mount folder name>

You can then use this either as a param to docker run like:

docker run -it -v /media/<mount folder name>:/media/<mount folder name>

or in docker compose under volumes:

services:
  whatevermyserviceis:
    volumes:
      - /media/<mount folder name>:/media/<mount folder name>

And now when you run and enter your container, you should be able to access the drive inside the container at /media/<mount folder name>

DISCLAIMER:

1. This will probably not work for serial devices such as webcams etc. I have only tested this for USB storage drives.
2. If you need to reconnect and disconnect devices regularly, this method would be annoying, and also would not work unless you reset the mount path and restart the container.
3. I used docker 17.06 + as prescribed in the docs

I arranged a little. This works great.

        Date date2 = dateFormat.parse(dateOfDay + " " + timeofday);

        printDifference(date1, date2);

    } catch (ParseException e) {
        e.printStackTrace();
    }

You should use .NET Core, instead of .NET Framework or Xamarin, in the following 6 typical scenarios according to the documentation here.

1. Cross-Platform needs

Clearly, if your goal is to have an application (web/service) that should be able to run across platforms (Windows, Linux and MacOS), the best choice in the .NET ecosystem is to use .NET Core as its runtime (CoreCLR) and libraries are cross-platform. The other choice is to use the Mono Project.

Both choices are open source, but .NET Core is directly and officially supported by Microsoft and will have a heavy investment moving forward.

When using .NET Core across platforms, the best development experience exists on Windows with the Visual Studio IDE which supports many productivity features including project management, debugging, source control, refactoring, rich editing including Intellisense, testing and much more. But rich development is also supported using Visual Studio Code on Mac, Linux and Windows including intellisense and debugging. Even third party editors like Sublime, Emacs, VI and more work well and can get editor intellisense using the open source Omnisharp project.

2. Microservices

When you are building a microservices oriented system composed of multiple independent, dynamically scalable, stateful or stateless microservices, the great advantage that you have here is that you can use different technologies/frameworks/languages at a microservice level. That allows you to use the best approach and technology per micro areas in your system, so if you want to build very performant and scalable microservices, you should use .NET Core. Eventually, if you need to use any .NET Framework library that is not compatible with .NET Core, there’s no issue, you can build that microservice with the .NET Framework and in the future you might be able to substitute it with the .NET Core.

The infrastructure platform you could use are many. Ideally, for large and complex microservice systems, you should use Azure Service Fabric. But for stateless microservices you can also use other products like Azure App Service or Azure Functions.

Note that as of June 2016, not every technology within Azure supports the .NET Core, but .NET Core support in Azure will be increasing dramatically now that .NET Core is RTM released.

3. Best performant and scalable systems

When your system needs the best possible performance and scalability so you get the best responsiveness no matter how many users you have, then is where .NET Core and ASP.NET Core really shine. The more you can do with the same amount of infrastructure/hardware, the richer the experience you’ll have for your end users – at a lower cost.

The days of Moore’s law performance improvements for single CPUs does not apply anymore; yet you need to do more while your system is growing and need higher scalability and performance for everyday’ s more demanding users which are growing exponentially in numbers. You need to get more efficient, optimize everywhere, and scale better across clusters of machines, VMs and CPU cores, ultimately. It is not just a matter of user’s satisfaction; it can also make a huge difference in cost/TCO. This is why it is important to strive for performance and scalability.

As mentioned, if you can isolate small pieces of your system as microservices or any other loosely-coupled approach, it’ll be better as you’ll be able to not just evolve each small piece/microservice independently and have a better long-term agility and maintenance, but also you’ll be able to use any other technology at a microservice level if what you need to do is not compatible with .NET Core. And eventually you’d be able to refactor it and bring it to .NET Core when possible.

4. Command line style development for Mac, Linux or Windows.

This approach is optional when using .NET Core. You can also use the full Visual Studio IDE, of course. But if you are a developer that wants to develop with lightweight editors and heavy use of command line, .NET Core is designed for CLI. It provides simple command line tools available on all supported platforms, enabling developers to build and test applications with a minimal installation on developer, lab or production machines. Editors like Visual Studio Code use the same command line tools for their development experiences. And IDE’s like Visual Studio use the same CLI tools but hide them behind a rich IDE experience. Developers can now choose the level they want to interact with the tool chain from CLI to editor to IDE.

5. Need side by side of .NET versions per application level.

If you want to be able to install applications with dependencies on different versions of frameworks in .NET, you need to use .NET Core which provides 100% side-by side as explained previously in this document.

6. Windows 10 UWP .NET apps.

Take a look at Simpleaudio, which is a relatively recent and lightweight library for this purpose:

> pip install simpleaudio

Then:

import simpleaudio as sa

wave_obj = sa.WaveObject.from_wave_file("path/to/file.wav")
play_obj = wave_obj.play()
play_obj.wait_done()

Make sure to use uncompressed 16 bit PCM files.

The Trace messages can occur in the output window as well, even if you're not in debug mode. You just have to make sure the the TRACE compiler constant is defined.

Instead Of using find(), One of the easy way is the Use of 'in' as above.

if 'substring' is present in 'str' then if part will execute otherwise else part will execute.

LIKE should work in sqlite:

require(sqldf)
df <- data.frame(name = c('bob','robert','peter'),id=c(1,2,3))
sqldf("select * from df where name LIKE '%er%'")
    name id
1 robert  2
2  peter  3

When require is given the path of a folder, it'll look for an index.js file in that folder; if there is one, it uses that, and if there isn't, it fails.

It would probably make most sense (if you have control over the folder) to create an index.js file and then assign all the "modules" and then simply require that.

yourfile.js

var routes = require("./routes");

index.js

exports.something = require("./routes/something.js");
exports.others = require("./routes/others.js");

If you don't know the filenames you should write some kind of loader.

Working example of a loader:

var normalizedPath = require("path").join(__dirname, "routes");

require("fs").readdirSync(normalizedPath).forEach(function(file) {
  require("./routes/" + file);
});

// Continue application logic here

this one is working

        $.get('1.txt', function(data) {
            //var fileDom = $(data);

            var lines = data.split("\n");

            $.each(lines, function(n, elem) {
                $('#myContainer').append('<div>' + elem + '</div>');
            });
        });

Is this what you are looking for ?

I wrote some macros that return the min and max of any type, regardless of signedness:

#define MAX_OF(type) \
    (((type)(~0LLU) > (type)((1LLU<<((sizeof(type)<<3)-1))-1LLU)) ? (long long unsigned int)(type)(~0LLU) : (long long unsigned int)(type)((1LLU<<((sizeof(type)<<3)-1))-1LLU))
#define MIN_OF(type) \
    (((type)(1LLU<<((sizeof(type)<<3)-1)) < (type)1) ? (long long int)((~0LLU)-((1LLU<<((sizeof(type)<<3)-1))-1LLU)) : 0LL)

Example code:

#include <stdio.h>
#include <sys/types.h>
#include <inttypes.h>

#define MAX_OF(type) \
    (((type)(~0LLU) > (type)((1LLU<<((sizeof(type)<<3)-1))-1LLU)) ? (long long unsigned int)(type)(~0LLU) : (long long unsigned int)(type)((1LLU<<((sizeof(type)<<3)-1))-1LLU))
#define MIN_OF(type) \
    (((type)(1LLU<<((sizeof(type)<<3)-1)) < (type)1) ? (long long int)((~0LLU)-((1LLU<<((sizeof(type)<<3)-1))-1LLU)) : 0LL)

int main(void)
{
    printf("uint32_t = %lld..%llu\n", MIN_OF(uint32_t), MAX_OF(uint32_t));
    printf("int32_t = %lld..%llu\n", MIN_OF(int32_t), MAX_OF(int32_t));
    printf("uint64_t = %lld..%llu\n", MIN_OF(uint64_t), MAX_OF(uint64_t));
    printf("int64_t = %lld..%llu\n", MIN_OF(int64_t), MAX_OF(int64_t));
    printf("size_t = %lld..%llu\n", MIN_OF(size_t), MAX_OF(size_t));
    printf("ssize_t = %lld..%llu\n", MIN_OF(ssize_t), MAX_OF(ssize_t));

1. npm install --save bootstrap

2. go to -> angular-cli.json file, find styles properties and just add next sting: "../node_modules/bootstrap/dist/css/bootstrap.min.css", It might be looks like this:

   "styles": [
   "../node_modules/bootstrap/dist/css/bootstrap.min.css",
   "styles.css"
   ],
   

If your post keys have to be parsed and the keys are sequences with data, you can try this:

Post data example: Storeitem|14=data14

foreach($_POST as $key => $value){
    $key=Filterdata($key); $value=Filterdata($value);
    echo($key."=".$value."<br>");
}

then you can use strpos to isolate the end of the key separating the number from the key.

I know this is too late to answer. But you may try these options:

Option 1: (Using curl)

$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "https://ifconfig.me/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// grab URL and pass it to the browser
$ip = curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);

return $ip;

Option 2: (Works good on mac)

return trim(shell_exec("dig +short myip.opendns.com @resolver1.opendns.com"));

Option 3: (Just used a trick)

return str_replace('Current IP CheckCurrent IP Address: ', '', strip_tags(file_get_contents('http://checkip.dyndns.com')));

MonoTouch and MonoDroid but what will happen to that part of Attachmate now is anybody's guess. Of course even with the mono solutions you're still creating non cross platform views but the idea being the reuse of business logic.

Keep an eye on http://www.xamarin.com/ it will be interesting to see what they come up with.

IoC concept was initially heard during the procedural programming era. Therefore from a historical context IoC talked about inversion of the ownership of control-flow i.e. who owns the responsibility to invoke the functions in the desired order - whether it's the functions themselves or should you invert it to some external entity.

However once the OOP emerged, people began to talk about IoC in OOP context where applications are concerned with object creation and their relationships as well, apart from the control-flow. Such applications wanted to invert the ownership of object-creation (rather than control-flow) and required a container which is responsible for object creation, object life-cycle & injecting dependencies of the application objects thereby eliminating application objects from creating other concrete object.

In that sense DI is not the same as IoC, since it's not about control-flow, however it's a kind of Io*, i.e. Inversion of ownership of object-creation.

What is wrong in my way of explainning DI and IoC?

ALTER TABLE Testing ALTER COLUMN TestDec decimal(16,1)

Just put decimal(precision, scale), replacing the precision and scale with your desired values.

I haven't done any testing with this with data in the table, but if you alter the precision, you would be subject to losing data if the new precision is lower.

absolute positioning is evil... this solution doesn't take into account window size. If you resize the browser window, your div will be out of place!

In the 'old days' you'd use a table and your menu items would be evenly spaced without having to explicitly state the width for the number of items.

If it wasn't for IE 6 and 7 (if that is of concern) then you can do the same in CSS.

<div class="demo">
    <span>Span 1</span>
    <span>Span 2</span>
    <span>Span 3</span>
</div>

CSS:

div.demo {
    display: table;
    width: 100%;
    table-layout: fixed;    /* For cells of equal size */
}
div.demo span {
    display: table-cell;
    text-align: center;
}

Without having to adjust for the number of items.

Example without table-layout:fixed - the cells are evenly distributed across the full width, but they are not necessarily of equal size since their width is determined by their contents.

• http://jsfiddle.net/w3dx/ULQwf/

Example with table-layout:fixed - the cells are of equal size, regardless of their contents. (Thanks to @DavidHerse in comments for this addition.)

• http://jsfiddle.net/kqHWM/

If you want the first and last menu elements to be left and right justified, then you can add the following CSS:

div.demo span:first-child {
    text-align: left;
}
div.demo span:last-child {
    text-align: right;
}

I removed the float from the second div to make it work.

To simulate an event, you could to use trigger JQuery functionnality.

$('#foo').on('click', function() {
      alert($(this).text());
    });
$('#foo').trigger('click');

Implement Comparable interface to Fruit.

public class Fruit implements Comparable<Fruit> {

It implements the method

@Override
    public int compareTo(Fruit fruit) {
        //write code here for compare name
    }

Then do call sort method

Collections.sort(fruitList);

Have you tried this:

PyGame Drawing Basics

Taken from the site:

pygame.draw.rect(screen, color, (x,y,width,height), thickness) draws a rectangle (x,y,width,height) is a Python tuple x,y are the coordinates of the upper left hand corner width, height are the width and height of the rectangle thickness is the thickness of the line. If it is zero, the rectangle is filled

The way you're doing it is correct.

You could use a trick like the one described here, using Linq expressions :

int value = ObjectA.NullSafeEval(x => x.PropertyA.PropertyB.PropertyC, 0);

But it's much slower that manually checking each property...

Unfortunately, there isn't a good way to browse for files with a JavaScript API. Fortunately, it's easy to create a file input in JavaScript, bind an event handler to its change event, and simulate a user clicking on it. We can do this without modifications to the page itself:

$('<input type="file" multiple>').on('change', function () {
  console.log(this.files);
}).click();

this.files on the second line is an array that contains filename, timestamps, size, and type.

Concatenate the string separating the slash and the word script in this way.

Response.Write("<script language='javascript'>alert('Especifique Usuario y Contraseña');</" + "script>");

To do POST you'll need to have a form.

<form action="employee.action" method="post">
    <input type="submit" value="Employee1" />
</form>

There are some ways to post data with hyperlinks, but you'll need some javascript, and a form.

Some tricks: Make a link use POST instead of GET and How do you post data with a link

Edit: to load response on a frame you can target your form to your frame:

<form action="employee.action" method="post" target="myFrame">

Here i have mentioned the simple syntex for create json file and print the array value inside the json file in pretty manner.

$array = array('name' => $name,'id' => $id,'url' => $url);
$fp = fopen('results.json', 'w');
fwrite($fp, json_encode($array, JSON_PRETTY_PRINT));   // here it will print the array pretty
fclose($fp);

Hope it will works for you....

my problem (git on macOS) was solved by using sudo git instead of just git in all add and commit commands

For collapse, you can try CTRL + M + O and expand using CTRL + M + P. This works in VS2008.

Its defined in RFC 2045 as a special padding character if fewer than 24 bits are available at the end of the encoded data.

After execute the thread, add these two line of code, and that will solve the issue.

Looper.loop();
Looper.myLooper().quit();

A quick update to Michael's excellent answer above.

For Rails 4.0+ you need to put your sort in a block like this:

class Book < ActiveRecord::Base
  default_scope { order('created_at DESC') }
end

Notice that the order statement is placed in a block denoted by the curly braces.

They changed it because it was too easy to pass in something dynamic (like the current time). This removes the problem because the block is evaluated at runtime. If you don't use a block you'll get this error:

Support for calling #default_scope without a block is removed. For example instead of default_scope where(color: 'red'), please use default_scope { where(color: 'red') }. (Alternatively you can just redefine self.default_scope.)

As @Dan mentions in his comment below, you can do a more rubyish syntax like this:

class Book < ActiveRecord::Base
  default_scope { order(created_at: :desc) }
end

or with multiple columns:

class Book < ActiveRecord::Base
  default_scope { order({begin_date: :desc}, :name) }
end

Thanks @Dan!

Honestly, Wikipedia might be the best place to look for an answer to this.

If NP = P, then we can solve very hard problems much faster than we thought we could before. If we solve only one NP-Complete problem in P (polynomial) time, then it can be applied to all other problems in the NP-Complete category.

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

As such there is no direct method to copy or rename index in ES (I did search extensively for my own project)

However a very easy option is to use a popular migration tool [Elastic-Exporter].

http://www.retailmenot.com/corp/eng/posts/2014/12/02/elasticsearch-cluster-migration/

[PS: this is not my blog, just stumbled upon and found it good]

Thereby you can copy index/type and then delete the old one.

Delete lines from all files that match the match

grep -rl 'text_to_search' . | xargs sed -i '/text_to_search/d'

You can directly go to http://127.0.0.1:8080/apex/f?p=4950 and you will get Home Page Of your Oracle Database.

Right click on the shortcut > choose properties > go to security tab > Choose Authenticated Users > and give permission to do everything

and now try to change the URL you will be able to do it.

In Rails 4.x (See http://edgeguides.rubyonrails.org/active_record_querying.html#not-conditions)

GroupUser.where.not(user_id: me)

In Rails 3.x

GroupUser.where(GroupUser.arel_table[:user_id].not_eq(me))

To shorten the length, you could store GroupUser.arel_table in a variable or if using inside the model GroupUser itself e.g., in a scope, you can use arel_table[:user_id] instead of GroupUser.arel_table[:user_id]

From this forum post

persist() is well defined. It makes a transient instance persistent. However, it doesn't guarantee that the identifier value will be assigned to the persistent instance immediately, the assignment might happen at flush time. The spec doesn't say that, which is the problem I have with persist().

persist() also guarantees that it will not execute an INSERT statement if it is called outside of transaction boundaries. This is useful in long-running conversations with an extended Session/persistence context.

A method like persist() is required.

save() does not guarantee the same, it returns an identifier, and if an INSERT has to be executed to get the identifier (e.g. "identity" generator, not "sequence"), this INSERT happens immediately, no matter if you are inside or outside of a transaction. This is not good in a long-running conversation with an extended Session/persistence context.

You may be able to use the JAVA_TOOL_OPTIONS environment variable to set options. It worked for me with Rasbian. See Environment Variables and System Properties which has this to say:

In many environments, the command line is not readily accessible to start the application with the necessary command-line options.

This often happens with applications that use embedded VMs (meaning they use the Java Native Interface (JNI) Invocation API to start the VM), or where the startup is deeply nested in scripts. In these environments the JAVA_TOOL_OPTIONS environment variable can be useful to augment a command line.

When this environment variable is set, the JNI_CreateJavaVM function (in the JNI Invocation API), the JNI_CreateJavaVM function adds the value of the environment variable to the options supplied in its JavaVMInitArgs argument.

However this environment variable use may be disabled for security reasons.

In some cases, this option is disabled for security reasons. For example, on the Oracle Solaris operating system, this option is disabled when the effective user or group ID differs from the real ID.

See this example showing the difference between specifying on the command line versus using the JAVA_TOOL_OPTIONS environment variable.

Building on @Pvl's answer, you can include type safety on your returned value as well if you use overrides:

First, attempt to pull from the same refspec that you are trying to push to.

If this does not work, you can force a git push by using git push -f <repo> <refspec>, but use caution: this method can cause references to be deleted on the remote repository.

This is taken from the docs and it works very well. Here is the link

• m - for classes that set margin
• p - for classes that set padding

Where sides are one of:

• t - for classes that set margin-top or padding-top
• b - for classes that set margin-bottom or padding-bottom
• l - for classes that set margin-left or padding-left
• r - for classes that set margin-right or padding-right

if you want to give margin to the left use mt-x where x stands for [1,2,3,4,5]

same for padding

example be like

<div class = "mt-5"></div>
<div class = "pt-5"></div>

Use only p-x or m-x for getting padding and margin of x from all sides.

Hope this will work:

counter = 1

for _ in range(players_numbers): #sum one, for the loop reach the correct number
    player_dict = {f'player{counter}': 0} #concatenate the word player with the player number. the initial point is 0.
    players.update(player_dict) #update the dictionary with every player

        "next": "???",
        "last": "????"
      },
      "aria": {
        "sortAscending": ": ????",
        "sortDescending": ": ????"
      }
    }
  };
  var language = dataTableLanguages[$('html').attr('lang')];

  var opts = {...};
  
  if (language) {
    if (typeof language === 'string') {
       opts.language = {
         url: language
       };
    } else {
       opts.language = language;
    }
  }

Now use the opts as option object for data table like

$('#list-table').DataTable(opts)

Say your variable is myNode, you can do myNode.value to retrieve the value of input elements.

Firebug has a "DOM" tab which shows useful DOM attributes.

Also see the mozilla page for a reference: https://developer.mozilla.org/en-US/docs/DOM/HTMLInputElement

Tested on 4.5.4:

            SSLContext sslContext = new SSLContextBuilder()
                    .loadTrustMaterial(null, (TrustStrategy) (arg0, arg1) -> true).build();

            CloseableHttpClient httpClient = HttpClients
                    .custom()
                    .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                    .setSSLContext(sslContext)
                    .build();

You could also use a RewriteRule if you wanted the ability to template match and redirect urls.

If you are unsure of the size of the array or if it can change you can do this to have a static array.

ArrayList<Player> thePlayersList = new ArrayList<Player>(); 

thePlayersList.add(new Player(1));
thePlayersList.add(new Player(2));
.
.
//Some code here that changes the number of players e.g

Players[] thePlayers = thePlayersList.toArray();

Including numbers but not whitespace:

"Stack Me 123 Heppa1 oeu".replaceAll("\\W","").toCharArray();

=> S, t, a, c, k, M, e, 1, 2, 3, H, e, p, p, a, 1, o, e, u

Without numbers and whitespace:

"Stack Me 123 Heppa1 oeu".replaceAll("[^a-z^A-Z]","").toCharArray()

=> S, t, a, c, k, M, e, H, e, p, p, a, o, e, u

If you want to revert a merge commit, here is what you have to do.

1. First, check the git log to find your merge commit's id. You'll also find multiple parent ids associated with the merge (see image below).

Note down the merge commit id shown in yellow. The parent IDs are the ones written in the next line as Merge: parent1 parent2. Now...

Short Story:

2. Switch to branch on which the merge was made. Then Just do the git revert <merge commit id> -m 1 which will open a vi console for entering commit message. Write, save, exit, done!

Long story:

2. Switch to branch on which the merge was made. In my case, it is the test branch and I'm trying to remove the feature/analytics-v3 branch from it.

3. git revert is the command which reverts any commit. But there is a nasty trick when reverting a merge commit. You need to enter the -m flag otherwise it will fail. From here on, you need to decide whether you want to revert your branch and make it look like exactly it was on parent1 or parent2 via:

git revert <merge commit id> -m 1 (reverts to parent2)

git revert <merge commit id> -m 2 (reverts to parent1)

You can git log these parents to figure out which way you want to go and that's the root of all the confusion.

Here is my aproach of explaining te rules .style and #style are part of a matrix. that if not in the right order, they can override each other, or cause conflicts.

Here is the line up.

Matrix

#style 0,0,1,0 id

.style 0,1,0,0 class

if you want override these two you can use <style></style> witch has a matrix level or 1,0,0,0. And @media query's will override everything above... I am not sure about this but i think the ID selector # can only be used once in a page.

The real problem here is that there is a bug in hibernate where it uses select-list aliases in the where-clause:

http://opensource.atlassian.com/projects/hibernate/browse/HHH-817

Just in case someone lands here looking for answers, go look at the ticket. It took 5 years to fix but in theory it'll be in one of the next releases and then I suspect your issue will go away.

Even I got the same issue and my mistake was that I didn't download python MSI file. You will get it here: https://www.python.org/downloads/

Once you download the msi, run the setup and that will solve the problem. After that you can go to File->Settings->Project Settings->Project Interpreter->Python Interpreters

and select the python.exe file. (This file will be available at c:\Python34) Select the python.exe file. That's it.

As @Nathan ended up with which is a simple HTTP Header, and some had said OAuth2 and client side SSL certificates. The gist of it is this... your REST API shouldn't have to handle security as that should really be outside the scope of the API.

Instead a security layer should be put on top of it, whether it is an HTTP Header behind a web proxy (a common approach like SiteMinder, Zermatt or even Apache HTTPd), or as complicated as OAuth 2.

The key thing is the requests should work without any end-user interaction. All that is needed is to ensure that the connection to the REST API is authenticated. In Java EE we have the notion of a userPrincipal that can be obtained on an HttpServletRequest. It is also managed in the deployment descriptor that a URL pattern can be secure so the REST API code does not need to check anymore.

In the WCF world, I would use ServiceSecurityContext.Current to get the current security context. You need to configure you application to require authentication.

There is one exception to the statement I had above and that's the use of a nonce to prevent replays (which can be attacks or someone just submitting the same data twice). That part can only be handled in the application layer.

If you are running SQL Server in a local environment and not over a TCP/IP connection. Go to Protocols under SQL Server Configuration Manager, Properties, and disable TCP/IP. Once this is done then the error message will go away when restarting the service.

You just need to set :

/usr/bin/php path_to_your_php_file

in your crontab.

>>> d = {}
>>> D = set()
>>> type(d)
<type 'dict'>
>>> type(D)
<type 'set'>

What you've made is a dictionary and not a Set.

The update method in dictionary is used to update the new dictionary from a previous one, like so,

>>> abc = {1: 2}
>>> d.update(abc)
>>> d
{1: 2}

Whereas in sets, it is used to add elements to the set.

>>> D.update([1, 2])
>>> D
set([1, 2])

You can try the following command:

git log --patch --color=always | less +/searching_string

or using grep in the following way:

git rev-list --all | GIT_PAGER=cat xargs git grep 'search_string'

Run this command in the parent directory where you would like to search.

[DataContract] and [DataMember] attribute are found in System.ServiceModel namespace which is in System.ServiceModel.dll .

System.ServiceModel uses the System and System.Runtime.Serialization namespaces to serialize the datamembers.

you need to specify the min and target sdk version in the manifest file.
If not the android.permission.READ_PHONE_STATE will be added automaticly while exporting your apk file.

<uses-sdk
        android:minSdkVersion="9"
        android:targetSdkVersion="19" />

You can't. This is an intentional design decision by the Git maintainers. Basically, the purpose of a Source Code Management System like Git is managing source code and empty directories aren't source code. Git is also often described as a content tracker, and again, empty directories aren't content (quite the opposite, actually), so they are not tracked.

Another option is to use JS:

<img src='LibraryTransparent.png' onmouseover="this.src='LibraryHoverTrans.png';" onmouseout="this.src='LibraryTransparent.png';" />

S3 does not have directories, while you can list files in a pseudo directory manner like you demonstrated, there is no directory "file" per-se.
You may of inadvertently created a data file called users/<user-id>/contacts/<contact-id>/.

The main difference is that Boolean is an object and boolean is an primitive.

• Object default value is null;
• boolean default value is false;

tr can be more concise for removing characters than sed or awk, especially when you want to remove different characters from a string.

Removing double quotes:

echo '"Hi"' | tr -d \"
# Produces Hi without quotes

Removing different kinds of brackets:

echo '[{Hi}]' | tr -d {}[]
# Produces Hi without brackets

-d stands for "delete".

Thanks to all, for me this solution worked: Magento 404 page in backoffice after login

Sometimes it's easier to think in terms of which fields to exclude.

If the number of fields not being cut (not being retained in the output) is small, it may be easier to use the --complement flag, e.g. to include all fields 1-20 except not 3, 7, and 12 -- do this:

cut -d, --complement -f3,7,12 <inputfile

Rather than

cut -d, -f-2,4-6,8-11,13-

You can use map :

List<String> names = 
    personList.stream()
              .map(Person::getName)
              .collect(Collectors.toList());

EDIT :

In order to combine the Lists of friend names, you need to use flatMap :

List<String> friendNames = 
    personList.stream()
              .flatMap(e->e.getFriends().stream())
              .collect(Collectors.toList());

If you can't change the member variable, then the other way around this is to use powerMockit and call

Second second = mock(Second.class)
when(second.doSecond()).thenReturn("Stubbed Second");
whenNew(Second.class).withAnyArguments.thenReturn(second);

Now the problem is that ANY call to new Second will return the same mocked instance. But in your simple case this will work.

No, cd / && tree && echo %time%. The time echoed is at when the first command is executed.

The piping has some issue, but it is not critical as long as people know how it works.

None of the top-voted answers worked for me, except when I unchecked "Use detected ADB location" as mentioned above by @???. Fortunately, in my case though, the message didn't show up, even when I turned it back on. In other words, the problem might be resolved by restarting "Use detected ADB location" :)

If someone is using bootstrap sass note the code is on the _reboot.scss file like this:

button:focus {
  outline: 1px dotted;
  outline: 5px auto -webkit-focus-ring-color;
}

So if you want to keep the _reboot file I guess feel free to override with plain css instead of trying to look for a variable to change.

first of all please check if docker-compose is installed,

$ docker-compose -v

If it is not installed, please refer to the installation guide https://docs.docker.com/compose/install/ If installed give executable permission to the binary.

$ chmod +x /usr/local/bin/docker-compose

check if this works.

I found a better way of doing this

  function genrateJSONEngine() {
    var XLSX = require('xlsx');
    var workbook = XLSX.readFile('test.xlsx');
    var sheet_name_list = workbook.SheetNames;
    sheet_name_list.forEach(function (y) {
      var array = workbook.Sheets[y];

      var first = array[0].join()
      var headers = first.split(',');

      var jsonData = [];
      for (var i = 1, length = array.length; i < length; i++) {

        var myRow = array[i].join();
        var row = myRow.split(',');

        var data = {};
        for (var x = 0; x < row.length; x++) {
          data[headers[x]] = row[x];
        }
        jsonData.push(data);

      }

I believe you can pass in event into the function inline which will be the event object for the raised event in W3C compliant browsers (i.e. older versions of IE will still require detection inside of your event handler function to look at window.event).

A quick example.

function sayHi(e) {_x000D_
   e.preventDefault();_x000D_
   alert("hi");_x000D_
}

<a href="http://google.co.uk" onclick="sayHi(event);">Click to say Hi</a>

1. Run it as is and notice that the link does no redirect to Google after the alert.
2. Then, change the event passed into the onclick handler to something else like e, click run, then notice that the redirection does take place after the alert (the result pane goes white, demonstrating a redirect).

If you would like to have live reload you can use gulp-webserver, which will watch for your file changes and reload page, this way you don't have to press F5 every time on your page:

Here is how to do it:

• Open command prompt (cmd) and type

  npm install --save-dev gulp-webserver

• Enter Ctrl+Shift+P in VS Code and type Configure Task Runner. Select it and press enter. It will open tasks.json file for you. Remove everything from it end enter just following code

tasks.json

{
    "version": "0.1.0",
    "command": "gulp",
    "isShellCommand": true,
    "args": [
        "--no-color"
    ],
    "tasks": [
        {
            "taskName": "webserver",
            "isBuildCommand": true,
            "showOutput": "always"
        }
    ]
}

• In the root directory of your project add gulpfile.js and enter following code:

gulpfile.js

var gulp = require('gulp'),
    webserver = require('gulp-webserver');

gulp.task('webserver', function () {
    gulp.src('app')
        .pipe(webserver({
            livereload: true,
            open: true
        }));
});

• Now in VS Code enter Ctrl+Shift+P and type "Run Task" when you enter it you will see your task "webserver" selected and press enter.

Your webserver now will open your page in your default browser. Now any changes that you will do to your HTML or CSS pages will be automatically reloaded.

Here is an information on how to configure 'gulp-webserver' for instance port, and what page to load, ...

You can also run your task just by entering Ctrl+P and type task webserver

Depending on the language you're using it's going to be something simple like

CInt(CDate("1970-1-1") - CDate(Today()))

Ironically enough, yesterday was day 40,000 if you use 1/1/1900 as "day zero" like many computer systems use.

my start.sh file:

#/bin/bash

nohup forever -c php artisan your:command >>storage/logs/yourcommand.log 2>&1 &

There is one important thing only. FIRST COMMAND MUST BE "nohup", second command must be "forever" and "-c" parameter is forever's param, "2>&1 &" area is for "nohup". After running this line then you can logout from your terminal, relogin and run "forever restartall" voilaa... You can restart and you can be sure that if script halts then forever will restart it.

I <3 forever

You need to put the format arguments into a tuple (add parentheses):

instr = "'%s', '%s', '%d', '%s', '%s', '%s', '%s'" % (softname, procversion, int(percent), exe, description, company, procurl)

What you currently have is equivalent to the following:

intstr = ("'%s', '%s', '%d', '%s', '%s', '%s', '%s'" % softname), procversion, int(percent), exe, description, company, procurl

Example:

>>> "%s %s" % 'hello', 'world'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: not enough arguments for format string
>>> "%s %s" % ('hello', 'world')
'hello world'

Simply:

DECLARE @MIN INT=3; --We define minimum value, it can be generated.
DECLARE @MAX INT=6; --We define maximum value, it can be generated.

SELECT @MIN+FLOOR((@MAX-@MIN+1)*RAND(CONVERT(VARBINARY,NEWID()))); --And then this T-SQL snippet generates an integer between minimum and maximum integer values.

You can change and edit this code for your needs.

Hi this is due to new version of the jQuery => 1.9.0

you can check the update : http://blog.jquery.com/2013/01/15/jquery-1-9-final-jquery-2-0-beta-migrate-final-released/

jQuery.Browser is deprecated. you can keep latest version by adding a migration script : http://code.jquery.com/jquery-migrate-1.0.0.js

replace :

<script src="http://code.jquery.com/jquery-latest.js"></script>

by :

<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.0.0.js"></script>

in your page and its working.

Scott Holden's blog entry on when to (and when not to) call GC.Collect is specific to the .NET Compact Framework, but the rules generally apply to all managed development.

The pattern is wrong. You have a 3-letter day abbreviation, so it must be EEE. You have a 3-letter month abbreviation, so it must be MMM. As those day and month abbreviations are locale sensitive, you'd like to explicitly specify the SimpleDateFormat locale to English as well, otherwise it will use the platform default locale which may not be English per se.

public static void main(String[] args) throws Exception {
    String target = "Thu Sep 28 20:29:30 JST 2000";
    DateFormat df = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy", Locale.ENGLISH);
    Date result =  df.parse(target);  
    System.out.println(result);
}

This prints here

Thu Sep 28 07:29:30 BOT 2000

which is correct as per my timezone.

I would also reconsider if you wouldn't rather like to use HH instead of kk. Read the javadoc for details about valid patterns.

The length function will do it. See http://www.techonthenet.com/oracle/functions/length.php

This is my workflow for merging selective files.

# Make a new branch (this will be temporary)
git checkout -b newbranch

# Grab the changes
git merge --no-commit  featurebranch

# Unstage those changes
git reset HEAD
(You can now see the files from the merge are unstaged)

# Now you can chose which files are to be merged.
git add -p

# Remember to "git add" any new files you wish to keep
git commit

Use Sum()

 List<string> foo = new List<string>();
 foo.Add("1");
 foo.Add("2");
 foo.Add("3");
 foo.Add("4");

 Console.Write(foo.Sum(x => Convert.ToInt32(x)));

Prints:

10

When none of the if test in number_translator() evaluate to true, the function returns None. The error message is the consequence of that.

Whenever you see an error that include 'NoneType' that means that you have an operand or an object that is None when you were expecting something else.

You can use setInterval:

var timer = setInterval( myFunction, 1000);

Just declare your function as myFunction or some other name, and then don't bind it to $('.more')'s live event.

If you are stuck with .NET 2.0 and managed code, here is another way that works whith local and domain accounts:

using System;
using System.Collections.Generic;
using System.Text;
using System.Security;
using System.Diagnostics;

static public bool Validate(string domain, string username, string password)
{
    try
    {
        Process proc = new Process();
        proc.StartInfo = new ProcessStartInfo()
        {
            FileName = "no_matter.xyz",
            CreateNoWindow = true,
            WindowStyle = ProcessWindowStyle.Hidden,
            WorkingDirectory = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData),
            UseShellExecute = false,
            RedirectStandardError = true,
            RedirectStandardOutput = true,
            RedirectStandardInput = true,
            LoadUserProfile = true,
            Domain = String.IsNullOrEmpty(domain) ? "" : domain,
            UserName = username,
            Password = Credentials.ToSecureString(password)
        };
        proc.Start();
        proc.WaitForExit();
    }
    catch (System.ComponentModel.Win32Exception ex)
    {
        switch (ex.NativeErrorCode)
        {
            case 1326: return false;
            case 2: return true;
            default: throw ex;
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }

    return false;
}   

For Ubuntu 18, after checking log file mentioned while install

Results logged to /var/canvas/vendor/bundle/ruby/2.5.0/extensions/x86_64-linux/2.5.0/nio4r-2.5.2/gem_make.out

with

less /var/canvas/vendor/bundle/ruby/2.5.0/extensions/x86_64-linux/2.5.0/nio4r-2.5.2/gem_make.out

I noticed that make is not found. So installed make by

sudo apt-get install make

everything worked.

There are overloads of ActionLink which take a fragment parameter. Passing "section12" as your fragment will get you the behavior you're after.

For example, calling LinkExtensions.ActionLink Method (HtmlHelper, String, String, String, String, String, String, Object, Object):

<%= Html.ActionLink("Link Text", "Action", "Controller", null, null, "section12-the-anchor", new { categoryid = "blah"}, null) %>

Maybe good ol' cfront will do?

You could access your class's __dict__ attribute:

for i in range(3)
     self.__dict__['group%d' % i]=self.getGroup(selected, header+i)

But why can't you just use an array named group?

Something like this would work

#!/bin/sh

if [ -fe FILE ]
then 
    rm FILE
fi 

-f checks if it's a regular file

-e checks if the file exist

Introduction to if for more information

EDIT : -e used with -f is redundant, fo using -f alone should work too

I didn't find application loader anywhere, even in spotlight. You can open it through xcode.

Go to Xcode > Open Developer Tools > Application Loader

$ kubectl replace --force -f <resource-file>

if all goes well, you should see something like:

<resource-type> <resource-name> deleted
<resource-type> <resource-name> replaced

details of this can be found in the Kubernetes documentation, "manage-deployment" and kubectl-cheatsheet pages at the time of writing.

The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.

The way you get your original array back is by using Convert.FromBase64String:

 byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);

you can also pyramid of stars like this

for (var i = 5; i >= 1; i--) {
     var py = "";
     for (var j = i; j >= 1; j--) {
         py += j;

     }
     console.log(py);
 }

You can check Announcing the official release of the Visual C++ Build Tools 2015 and from this blog, we can know that the Build Tools are the same C++ tools that you get with Visual Studio 2015 but they come in a scriptable standalone installer that only lays down the tools you need to build C++ projects. The Build Tools give you a way to install the tools you need on your build machines without the IDE you don’t need.

Because these components are the same as the ones installed by the Visual Studio 2015 Update 2 setup, you cannot install the Visual C++ Build Tools on a machine that already has Visual Studio 2015 installed. Therefore, it asks you to uninstall your existing VS 2015 when you tried to install the Visual C++ build tools using the standalone installer. Since you already have the VS 2015, you can go to Control Panel—Programs and Features and right click the VS 2015 item and Change-Modify, then check the option of those components that relates to the Visual C++ Build Tools, like Visual C++, Windows SDK… then install them. After the installation is successful, you can build the C++ projects.

Here's my simple solution to update the query params in the URL without refreshing the page. Make sure it works for your use case.

const query = { ...this.$route.query, someParam: 'some-value' };
this.$router.replace({ query });

I am assuming you know the length of the part before the _ and after the underscore, as well as the extension. If you don't it might be more complex than a simple substring.

cd C:\path\to\the\files
for /f %%a IN ('dir /b *.jpg') do (
set p=%a:~0,3%
set q=%a:~4,4%
set b=%p_%q.jpg
ren %a %b
)

I just came up with this script, and I did not test it. Check out this and that for more info.

IF you want to assume you don't know the positions of the _ and the lengths and the extension, I think you could do something with for loops to check the index of the _, then the last index of the ., wrap it in a goto thing and make it work. If you're willing to go through that trouble, I'd suggest you use WindowsPowerShell (or Cygwin) at least (for your own sake) or install a more advanced scripting language (think Python/Perl) you'll get more support either way.

Try using this:

<script src="http://maps.googleapis.com/maps/api/js?sensor=false"></script> 

It will hopefully be available soon in Javascript, as it is in proposal phase as of Apr, 2020. You can monitor the status here for compatibility and support - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Nullish_coalescing_operator

For people using Typescript, you can use the nullish coalescing operator from Typescript 3.7

From the docs -

You can think of this feature - the ?? operator - as a way to “fall back” to a default value when dealing with null or undefined. When we write code like

let x = foo ?? bar();

this is a new way to say that the value foo will be used when it’s “present”; but when it’s null or undefined, calculate bar() in its place.

That's a difficult problem to solve since visually similar PDFs may have a wildly differing structure depending on how they were produced. In the worst case the library would need to basically act like an OCR. On the other hand, the PDF may contain sufficient structure and metadata for easy removal of tables and figures, which the library can be tailored to take advantage of.

I'm pretty sure there are no open source tools which solve your problem for a wide variety of PDFs, but I remember having heard of commercial software claiming to do exactly what you ask for. I'm sure you'll run into them while googling.

Faced same issue, Try using JPG format !! What worked for me here was using a jpg file instead of PNG as jpg files don't use alpha or transparency features. I did it via online image converter or you can also open the image in preview and then File->Export and uncheck alpha as option to save the image and use this image.

Or you could use the CURRENT_DATE alternative, with the same result:

SELECT * FROM yourtable WHERE created >= CURRENT_DATE

Examples from database.guide

Because Test discovery seems to be a complete subject, there is some dedicated framework to test discovery :

• nose
• Py.Test

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

You can access values in the $_POST array by their key. $_POST is an associative array, so to access taskOption you would use $_POST['taskOption'];.

Make sure to check if it exists in the $_POST array before proceeding though.

<form method="post" action="process.php">
  <select name="taskOption">
    <option value="first">First</option>
    <option value="second">Second</option>
    <option value="third">Third</option>
  </select>
  <input type="submit" value="Submit the form"/>
</form>

process.php

<?php
   $option = isset($_POST['taskOption']) ? $_POST['taskOption'] : false;
   if ($option) {
      echo htmlentities($_POST['taskOption'], ENT_QUOTES, "UTF-8");
   } else {
     echo "task option is required";
     exit; 
   }

If you do not work with fig and ax and you want to modify all labels (e.g. for normalization) you can do this:

labels, locations = plt.yticks()
plt.yticks(labels, labels/max(labels))

I connected to a VPN and the connection accomplished. I was using school's WiFi which has some restrictions apparently.

If you're OK with littering your markup a bit, you could do it the easy way and just wrap your <button> with an anchor (<a>) link.

<a href="#/new-page.html"><button>New Page<button></a>

Also, there is nothing stopping you from styling an anchor link to look like a <button>

as pointed out in the comments by @tronman, this is not technically valid html5, but it should not cause any problems in practice

Do you realy want to return null ? Something you can do, is maybe initialise savedkey with 0 value and return 0 as a null value. It can be more simple.

You can add parameter columns or use dict with key which is converted to column name:

np.random.seed(123)
e = np.random.normal(size=10)  
dataframe=pd.DataFrame(e, columns=['a']) 
print (dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

e_dataframe=pd.DataFrame({'a':e}) 
print (e_dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

You may try with the below code

override func viewDidAppear(_ animated: Bool) {
    self.navigationController?.isNavigationBarHidden = true
}

I found App called Iconizer. You can find repository on github. Iconizer can generate app icons for OS X, iPad, iPhone, CarPlay and Apple Watch with just one image.

Simply Drag and Drop your icon onto Iconizer, select the platforms you need and whether or not you want all platforms generated into one asset catalog, then hit export.

After that just replace (delete and import) your AppIcon in the Assets.xcassets

Using regular expressions - documentation for further reference

import re

text = 'gfgfdAAA1234ZZZuijjk'

m = re.search('AAA(.+?)ZZZ', text)
if m:
    found = m.group(1)

# found: 1234

or:

import re

text = 'gfgfdAAA1234ZZZuijjk'

try:
    found = re.search('AAA(.+?)ZZZ', text).group(1)
except AttributeError:
    # AAA, ZZZ not found in the original string
    found = '' # apply your error handling

# found: 1234

This can happen if you have a newline (or other control character) in a JSON string literal.

{"foo": "bar
baz"}

If you are the one producing the data, replace actual newlines with escaped ones "\\n" when creating your string literals.

{"foo": "bar\nbaz"}

The globals() function returns a dictionary containing all your global variables.

>>> apple = 1
>>> banana = 'f'
>>> carrot = 3
>>> globals()
{'carrot': 3, 'apple': 1, '__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__doc__': None, 'banana': 'f'}

There is also a similar function called locals().

I realise this is probably not exactly what you want, but it may provide some insight into how Python provides access to your variables.

Edit: It sounds like your problem may be better solved by simply using a dictionary in the first place:

fruitdict = {}
fruitdict['apple'] = 1
fruitdict['banana'] = 'f'
fruitdict['carrot'] = 3

I find using vintage mode works really well with sublime multiselect.

My most used keys would be "w" for jumping a word, "^" and "$" to move to first/last character of the line. Combinations like "2dw" (delete the next two words after the cursor) make using multiselect really powerful.

This sounds obvious but has really sped up my workflow, especially when editing HTML.

I think there is little difference between the two events. To understand this, I created a simple example to manipulation:

XAML

<Window x:Class="LoadedAndContentRendered.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Name="MyWindow"
        Title="MainWindow" Height="1000" Width="525"
        WindowStartupLocation="CenterScreen"
        ContentRendered="Window_ContentRendered"     
        Loaded="Window_Loaded">

    <Grid Name="RootGrid">        
    </Grid>
</Window>

Code behind

private void Window_ContentRendered(object sender, EventArgs e)
{
    MessageBox.Show("ContentRendered");
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Loaded");
}   

In this case the message Loaded appears the first after the message ContentRendered. This confirms the information in the documentation.

In general, in WPF the Loaded event fires if the element:

is laid out, rendered, and ready for interaction.

Since in WPF the Window is the same element, but it should be generally content that is arranged in a root panel (for example: Grid). Therefore, to monitor the content of the Window and created an ContentRendered event. Remarks from MSDN:

If the window has no content, this event is not raised.

That is, if we create a Window:

<Window x:Class="LoadedAndContentRendered.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Name="MyWindow"        
    ContentRendered="Window_ContentRendered" 
    Loaded="Window_Loaded" />

It will only works Loaded event.

With regard to access to the elements in the Window, they work the same way. Let's create a Label in the main Grid of Window. In both cases we have successfully received access to Width:

private void Window_ContentRendered(object sender, EventArgs e)
{
    MessageBox.Show("ContentRendered: " + SampleLabel.Width.ToString());
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Loaded: " + SampleLabel.Width.ToString());
}   

As for the Styles and Templates, at this stage they are successfully applied, and in these events we will be able to access them.

For example, we want to add a Button:

private void Window_ContentRendered(object sender, EventArgs e)
{
    MessageBox.Show("ContentRendered: " + SampleLabel.Width.ToString());

    Button b1 = new Button();
    b1.Content = "ContentRendered Button";
    RootGrid.Children.Add(b1);
    b1.Height = 25;
    b1.Width = 200;
    b1.HorizontalAlignment = HorizontalAlignment.Right;
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Loaded: " + SampleLabel.Width.ToString());

    Button b1 = new Button();
    b1.Content = "Loaded Button";
    RootGrid.Children.Add(b1);
    b1.Height = 25;
    b1.Width = 200;
    b1.HorizontalAlignment = HorizontalAlignment.Left;
}

In the case of Loaded event, Button to add to Grid immediately at the appearance of the Window. In the case of ContentRendered event, Button to add to Grid after all its content will appear.

Therefore, if you want to add items or changes before load Window you must use the Loaded event. If you want to do the operations associated with the content of Window such as taking screenshots you will need to use an event ContentRendered.

You can also DB tool Navicat, which does it more easier.

I saw a question the other day where someone inadvertently used an incomplete type by specifying something like

struct a {
    int q; 
}; 
struct A *x; 
x->q = 3;

The compiler knew that struct A was a struct, despite A being totally undefined, by virtue of the struct keyword.

That was in C++, where such usage of struct is atypical (and, it turns out, can lead to foot-shooting). In C if you do

typedef struct a {
    ...
} a;

then you can use a as the typename and omit the struct later. This will lead the compiler to give you an undefined identifier error later, rather than incomplete type, if you mistype the name or forget a header.

I want to say hello from the future :) Things that happened recently:

1. Google now runs javascript that is on your website¹
2. People now use things like React.js, Ember and Angular to run complex javascript tasks on the page and it's still getting indexed by Google¹
3. you can use html5 history api (pushState, react-router, ember, angular) that allows you to do things like have separate urls for each tab you want to open and Google will index that¹

So to answer your question you can safely change title and other meta tags from javascript (you can also add something like https://prerender.io if you want to support non-Google search engines), just make them accessible as separate urls (otherwise how Google would know that those are different pages to show in search results?). Changing SEO related tags (after user has changed page by clicking on something) is simple:

if (document.title != newTitle) {
    document.title = newTitle;
}
$('meta[name="description"]').attr("content", newDescription);

Just make sure that css and javascript is not blocked in robots.txt, you can use Fetch as Google service in Google Webmaster Tools.

ddd is a graphical front-end to gdb that is pretty nice. One of the down sides is a classic X interface, but I seem to recall it being pretty intuitive.

As far as I understand it correctly, I think it's easiest to work with 4 lists: - Your sourceList - Your destinationList - A removedItemsList - A newlyAddedItemsList

In my case, space was entered in the column during the data import and though it looked like an empty column its length was 1. So first of all I checked the length of the empty looking column using length(column) then based on this we can write search query

SELECT * FROM TABLE WHERE LENGHT(COLUMN)= 0;

You could have multiple Python versions on your macOS.

You may check that by command, type or which command, like:

which -a python python2 python2.7 python3 python3.6

Or type python in Terminal and hit Tab few times for auto completion, which is equivalent to:

compgen -c python

By default python/pip commands points to the first binary found in PATH environment variable depending what's actually installed. So before installing Python packages with Homebrew, the default Python is installed in /usr/bin which is shipped with your macOS (e.g. Python 2.7.10 on High Sierra). Any versions found in /usr/local (such as /usr/local/bin) are provided by external packages.

It is generally advised, that when working with multiple versions, for Python 2 you may use python2/pip2 command, respectively for Python 3 you can use python3/pip3, but it depends on your configuration which commands are available.

It is also worth to mention, that since release of Homebrew 1.5.0+ (on 19 January 2018), the python formula has been upgraded to Python 3.x and a python@2 formula will be added for installing Python 2.7. Before, python formula was pointing to Python 2.

For instance, if you've installed different version via Homebrew, try the following command:

brew list python python3

or:

brew list | grep ^python

it'll show you all Python files installed with the package.

Alternatively you may use apropos or locate python command to locate more Python related files.

To check any environment variables related to Python, run:

env | grep ^PYTHON

To address your issues:

• Error: No such keg: /usr/local/Cellar/python

  Means you don't have Python installed via Homebrew. However double check by specifying only one package at a time (like brew list python python2 python3).

• The locate database (/var/db/locate.database) does not exist.

  Follow the advice and run:

  sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist
  

  After the database is rebuild, you can use locate command.

The problem is that your imgs will always bump down to the next line because of the containing div.

In order to get around this, you need to place the imgs in their own div with a width wide enough to hold all of them. Then you can use your styles as is.

So, when I set the imgs to 120px each and place them inside a

div#insideDiv{
    width:800px;
}

it all works.

Adjust width as necessary.

When you use a web service you have a client and a server:

1. If the server fails the client must take responsibility to handle the error.
2. When the server is working again the client is responsible of resending it.
3. If the server gives a response to the call and the client fails the operation is lost.
4. You don't have contention, that is: if million of clients call a web service on one server in a second, most probably your server will go down.
5. You can expect an immediate response from the server, but you can handle asynchronous calls too.

When you use a message queue like RabbitMQ, Beanstalkd, ActiveMQ, IBM MQ Series, Tuxedo you expect different and more fault tolerant results:

1. If the server fails, the queue persist the message (optionally, even if the machine shutdown).
2. When the server is working again, it receives the pending message.
3. If the server gives a response to the call and the client fails, if the client didn't acknowledge the response the message is persisted.
4. You have contention, you can decide how many requests are handled by the server (call it worker instead).
5. You don't expect an immediate synchronous response, but you can implement/simulate synchronous calls.

Message Queues has a lot more features but this is some rule of thumb to decide if you want to handle error conditions yourself or leave them to the message queue.

Just for completion, this is the code from google guava library. It is not my code, but I think it is valueable to show it here in this thread.

  /** Maximum loop count when creating temp directories. */
  private static final int TEMP_DIR_ATTEMPTS = 10000;

  /**
   * Atomically creates a new directory somewhere beneath the system's temporary directory (as
   * defined by the {@code java.io.tmpdir} system property), and returns its name.
   *
   * <p>Use this method instead of {@link File#createTempFile(String, String)} when you wish to
   * create a directory, not a regular file. A common pitfall is to call {@code createTempFile},

   *
   * <p>This method assumes that the temporary volume is writable, has free inodes and free blocks,
   * and that it will not be called thousands of times per second.
   *
   * @return the newly-created directory
   * @throws IllegalStateException if the directory could not be created
   */
  public static File createTempDir() {
    File baseDir = new File(System.getProperty("java.io.tmpdir"));
    String baseName = System.currentTimeMillis() + "-";

    for (int counter = 0; counter < TEMP_DIR_ATTEMPTS; counter++) {
      File tempDir = new File(baseDir, baseName + counter);
      if (tempDir.mkdir()) {
        return tempDir;
      }
    }
    throw new IllegalStateException(
        "Failed to create directory within "
            + TEMP_DIR_ATTEMPTS
            + " attempts (tried "
            + baseName
            + "0 to "
            + baseName
            + (TEMP_DIR_ATTEMPTS - 1)
            + ')');
  }

I think the beginning to the resolution to this issue is the fact that the use of the for loop or any other function or action can not be done in the class definition but needs to be included in a method/constructor/block definition inside of a class.

What if you are using this to determine the current selector to find its children so this holds: <ol> then there is <li>s under how to write a selector var count = $(this+"> li").length; wont work..

@robert-hurst has a cleaner approach.

However, this solution may also be used, in places when you actually want to have a copy of Data Url after copying. For example, when you are building a website that uses lots of image/canvas operations.

    // select canvas elements
    var sourceCanvas = document.getElementById("some-unique-id");
    var destCanvas = document.getElementsByClassName("some-class-selector")[0];

    //copy canvas by DataUrl
    var sourceImageData = sourceCanvas.toDataURL("image/png");
    var destCanvasContext = destCanvas.getContext('2d');

    var destinationImage = new Image;
    destinationImage.onload = function(){
      destCanvasContext.drawImage(destinationImage,0,0);
    };
    destinationImage.src = sourceImageData;

You don't necessarily have to choose between the two paradigms. You can write software with an OO architecture using many functional concepts. FP and OOP are orthogonal in nature.

Take for example C#. You could say it's mostly OOP, but there are many FP concepts and constructs. If you consider Linq, the most important constructs that permit Linq to exist are functional in nature: lambda expressions.

Another example, F#. You could say it's mostly FP, but there are many OOP concepts and constructs available. You can define classes, abstract classes, interfaces, deal with inheritance. You can even use mutability when it makes your code clearer or when it dramatically increases performance.

Many modern languages are multi-paradigm.

Recommended readings

As I'm in the same boat (OOP background, learning FP), I'd suggest you some readings I've really appreciated:

• Functional Programming for Everyday .NET Development, by Jeremy Miller. A great article (although poorly formatted) showing many techniques and practical, real-world examples of FP on C#.

• Real-World Functional Programming, by Tomas Petricek. A great book that deals mainly with FP concepts, trying to explain what they are, when they should be used. There are many examples in both F# and C#. Also, Petricek's blog is a great source of information.

Try moving the seed srand outside the loop like so:

srand ( time(NULL) );
for (int t=0;t<10;t++)
{
    int random_x;
    random_x = rand() % 100;
    cout<< "\nRandom X = "<<random_x;
} 

As Mark Ransom says in the comment, moving the seed outside the loop will only help if the loop is not residing in a function you are calling several times.

HTML5 spec:

http://www.w3.org/TR/html5/forms.html#enabling-and-disabling-form-controls:-the-disabled-attribute :

The checked content attribute is a boolean attribute

http://www.w3.org/TR/html5/infrastructure.html#boolean-attributes :

The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.

If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace.

Conclusion:

The following are valid, equivalent and true:

<input type="text" disabled />
<input type="text" disabled="" />
<input type="text" disabled="disabled" />
<input type="text" disabled="DiSaBlEd" />

The following are invalid:

<input type="text" disabled="0" />
<input type="text" disabled="1" />
<input type="text" disabled="false" />
<input type="text" disabled="true" />

The absence of the attribute is the only valid syntax for false:

<input type="text" />

Recommendation

If you care about writing valid XHTML, use disabled="disabled", since <input disabled> is invalid and other alternatives are less readable. Else, just use <input disabled> as it is shorter.

Here's a partial solution using xml2. Breaking the solution up into smaller pieces generally makes it easier to ensure everything is lined up:

library(xml2)
data <- read_xml("http://forecast.weather.gov/MapClick.php?lat=29.803&lon=-82.411&FcstType=digitalDWML")

# Point locations
point <- data %>% xml_find_all("//point")
point %>% xml_attr("latitude") %>% as.numeric()
point %>% xml_attr("longitude") %>% as.numeric()

# Start time
data %>% 
  xml_find_all("//start-valid-time") %>% 
  xml_text()

# Temperature
data %>% 
  xml_find_all("//temperature[@type='hourly']/value") %>% 
  xml_text() %>% 
  as.integer()

You can do this in many ways before clicking on add items:

WebDriverWait wait = new WebDriverWait(driver, 40);
wait.until(ExpectedConditions.elementToBeClickable(By.id("urelementid")));// instead of id u can use cssSelector or xpath of ur element.


or

wait.until(ExpectedConditions.visibilityOfElementLocated("urelement"));

You can also wait like this. If you want to wait until invisible of previous page element:

wait.until(ExpectedConditions.invisibilityOfElementLocated("urelement"));

Here is the link where you can find all the Selenium WebDriver APIs that can be used for wait and its documentation.

https://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/support/ui/ExpectedConditions.html

You can resize and then use imagejpeg()

Don't pass 100 as the quality for imagejpeg() - anything over 90 is generally overkill and just gets you a bigger JPEG. For a thumbnail, try 75 and work downwards until the quality/size tradeoff is acceptable.

imagejpeg($tn, $save, 75);

This is what I do on debian - I suspect it should work on ubuntu (amend the version as required + adapt the folder where you want to copy the JDK files as you wish, I'm using /opt/jdk):

wget --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u71-b15/jdk-8u71-linux-x64.tar.gz
sudo mkdir /opt/jdk
sudo tar -zxf jdk-8u71-linux-x64.tar.gz -C /opt/jdk/
rm jdk-8u71-linux-x64.tar.gz

Then update-alternatives:

sudo update-alternatives --install /usr/bin/java java /opt/jdk/jdk1.8.0_71/bin/java 1
sudo update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk1.8.0_71/bin/javac 1

Select the number corresponding to the /opt/jdk/jdk1.8.0_71/bin/java when running the following commands:

sudo update-alternatives --config java
sudo update-alternatives --config javac

Finally, verify that the correct version is selected:

java -version
javac -version

1. Go to tools->options.
2. Make sure the above check boxes are checked.

While out of the box, MongoDb has no authentication, you can create the equivalent of a root/superuser by using the "any" roles to a specific user to the admin database.

Something like this:

use admin
db.addUser( { user: "<username>",
          pwd: "<password>",
          roles: [ "userAdminAnyDatabase",
                   "dbAdminAnyDatabase",
                   "readWriteAnyDatabase"

] } )

Update for 2.6+

While there is a new root user in 2.6, you may find that it doesn't meet your needs, as it still has a few limitations:

Provides access to the operations and all the resources of the readWriteAnyDatabase, dbAdminAnyDatabase, userAdminAnyDatabase and clusterAdmin roles combined.

root does not include any access to collections that begin with the system. prefix.

Update for 3.0+

Use db.createUser as db.addUser was removed.

Update for 3.0.7+

root no longer has the limitations stated above.

The root has the validate privilege action on system. collections. Previously, root does not include any access to collections that begin with the system. prefix other than system.indexes and system.namespaces.

This is iteration using block approach:

    NSDictionary *dict = @{@"key1":@1, @"key2":@2, @"key3":@3};

    [dict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
        NSLog(@"%@->%@",key,obj);
        // Set stop to YES when you wanted to break the iteration.
    }];

With autocompletion is very fast to set, and you do not have to worry about writing iteration envelope.

If you are a linux user:

To show the engines for all tables for all databases on a mysql server, without tables information_schema, mysql, performance_schema:

less < <({ for i in $(mysql -e "show databases;" | cat | grep -v -e Database-e information_schema -e mysql -e performance_schema); do echo "--------------------$i--------------------";  mysql -e "use $i; show table status;"; done } | column -t)

You might love this, if you are on linux, at least.

Will open all info for all tables in less, press -S to chop overly long lines.

Example output:

For Dark Mode Only: -

I have used Raleway Font for styling

To C:\User\UserName\.jupyter\custom\custom.css file

append the given styles, this is specifically for Dark Mode for jupyter notebook...

This should be your current custom.css file: -

/* This file contains any manual css for this page that needs to override the global styles.
    This is only required when different pages style the same element differently. This is just
    a hack to deal with our current css styles and no new styling should be added in this file.*/

Try enclosing your date into a character string.

 select * 
 from dbo.March2010 A
 where A.Date >= '2010-04-01';

Before:

boolean result = isresult();
if (result) {
    result = false;
} else {
    result = true;
}

After:

boolean result = isresult();
result ^= true;

   var stringToSplit = "0, 10, 20, 30, 100, 200";

    // To parse your string 
    var elements = test.Split(new[]
    { ',' }, System.StringSplitOptions.RemoveEmptyEntries);

    // To Loop through
    foreach (string items in elements)
    {
       // enjoy
    }

I'm going to expand your question a bit and also include the compile function.

• compile function - use for template DOM manipulation (i.e., manipulation of tElement = template element), hence manipulations that apply to all DOM clones of the template associated with the directive. (If you also need a link function (or pre and post link functions), and you defined a compile function, the compile function must return the link function(s) because the 'link' attribute is ignored if the 'compile' attribute is defined.)

• link function - normally use for registering listener callbacks (i.e., $watch expressions on the scope) as well as updating the DOM (i.e., manipulation of iElement = individual instance element). It is executed after the template has been cloned. E.g., inside an <li ng-repeat...>, the link function is executed after the <li> template (tElement) has been cloned (into an iElement) for that particular <li> element. A $watch allows a directive to be notified of scope property changes (a scope is associated with each instance), which allows the directive to render an updated instance value to the DOM.

• controller function - must be used when another directive needs to interact with this directive. E.g., on the AngularJS home page, the pane directive needs to add itself to the scope maintained by the tabs directive, hence the tabs directive needs to define a controller method (think API) that the pane directive can access/call.
  
  For a more in-depth explanation of the tabs and pane directives, and why the tabs directive creates a function on its controller using this (rather than on $scope), please see 'this' vs $scope in AngularJS controllers.

In general, you can put methods, $watches, etc. into either the directive's controller or link function. The controller will run first, which sometimes matters (see this fiddle which logs when the ctrl and link functions run with two nested directives). As Josh mentioned in a comment, you may want to put scope-manipulation functions inside a controller just for consistency with the rest of the framework.

If you are using OpenLDAP (i.e. slapd) which is common on Linux servers, then you must enable the memberof overlay to be able to match against a filter using the (memberOf=XXX) attribute.

Also, once you enable the overlay, it does not update the memberOf attributes for existing groups (you will need to delete out the existing groups and add them back in again). If you enabled the overlay to start with, when the database was empty then you should be OK.
