Let's assume you have such history

---o---o---o---M---W---x-------x-------*
              /                      
      ---A---B

Where A, B failed commits and W - is revert of M

So before I start fixing found problems I do cherry-pick of W commit to my branch

git cherry-pick -x W

Then I revert W commit on my branch

git revert W 

After I can continue fixing.

The final history could look like:

---o---o---o---M---W---x-------x-------*
              /                       /     
      ---A---B---W---W`----------C---D

When I send a PR it will clearly shows that PR is undo revert and adds some new commits.

For e.g. when a user has login.Now lets say the user want to create a forum topic, How will I know that the user is already logged in?

Think about it - there must be some handshake that tells your "Create Forum" API that this current request is from an authenticated user. Since REST APIs are typically stateless, the state must be persisted somewhere. Your client consuming the REST APIs is responsible for maintaining that state. Usually, it is in the form of some token that gets passed around since the time the user was logged in. If the token is good, your request is good.

Check how Amazon AWS does authentications. That's a perfect example of "passing the buck" around from one API to another.

*I thought of adding some practical response to my previous answer. Try Apache Shiro (or any authentication/authorization library). Bottom line, try and avoid custom coding. Once you have integrated your favorite library (I use Apache Shiro, btw) you can then do the following:

1. Create a Login/logout API like: /api/v1/login and api/v1/logout
2. In these Login and Logout APIs, perform the authentication with your user store
3. The outcome is a token (usually, JSESSIONID) that is sent back to the client (web, mobile, whatever)
4. From this point onwards, all subsequent calls made by your client will include this token
5. Let's say your next call is made to an API called /api/v1/findUser
6. The first thing this API code will do is to check for the token ("is this user authenticated?")
7. If the answer comes back as NO, then you throw a HTTP 401 Status back at the client. Let them handle it.
8. If the answer is YES, then proceed to return the requested User

That's all. Hope this helps.

Use isset()

$matchFound = (isset($_GET["id"]) && trim($_GET["id"]) == 'link1');
$slide = $matchFound ? trim($_GET["id"]) : '';

EDIT: This is added for the completeness sake. $_GET in php is a reserved variable that is an associative array. Hence, you could also make use of 'array_key_exists(mixed $key, array $array)'. It will return a boolean that the key is found or not. So, the following also will be okay.

$matchFound = (array_key_exists("id", $_GET)) && trim($_GET["id"]) == 'link1');
$slide = $matchFound ? trim($_GET["id"]) : '';

Late to the party here, but I also find that I use the following. Some may only be useful for hiding sensitive files when pushing to a public remote.

#Ignore email files delivered to specified pickup directory
*.eml

#Allow NuGet.exe (do not ignore)
!NuGet.exe

#Ignore WebDeploy publish profiles
*.Publish.xml

#Ignore Azure build csdef & Pubxml files
ServiceDefinition.build.csdef
*.azurePubxml

#Allow ReSharper .DotSettings (for non-namespace-provider properties)
!*.csproj.DotSettings

#Ignore private folder
/Private/

If you don't want to display popup for all event you can add conditions like

window.onbeforeunload = confirmExit;
    function confirmExit() {
        if (isAnyTaskInProgress) {
           return "Some task is in progress. Are you sure, you want to close?";
        }
    }

This works fine for me

We're all working around some old bugs that haven't been fixed likely because it's "by design." I ran into the freezing problem @iwasrobbed described elsewhere when trying to nil the interactivePopGestureRecognizer's delegate which seemed like it should've worked. If you want swipe behavior reconsider using backBarButtonItem which you can customize.

I also ran into interactivePopGestureRecognizer not working when the UINavigationBar is hidden. If hiding the navigation bar is a concern for you, reconsider your design before implementing a workaround for a bug.

Perl 6 has the say function that automatically appends \n.

You can also use say in Perl 5.10 or 5.12 if you add

use feature qw(say);

to the beginning of your program. Or you can use Modern::Perl to get this and other features.

See perldoc feature for more details.

You should really post:

1. The complete source code of your example
2. The actual result of it, not a summary

Here is my code, which works:

import socket, sys

def alert(msg):
    print >>sys.stderr, msg
    sys.exit(1)

(family, socktype, proto, garbage, address) = \
         socket.getaddrinfo("::1", "http")[0] # Use only the first tuple
s = socket.socket(family, socktype, proto)

try:
    s.connect(address) 
except Exception, e:
    alert("Something's wrong with %s. Exception type is %s" % (address, e))

When the server listens, I get nothing (this is normal), when it doesn't, I get the expected message:

Something's wrong with ('::1', 80, 0, 0). Exception type is (111, 'Connection refused')

I agree totally with the OP point of view. Assert.assertFalse(expected.equals(actual)) is not a natural way to express an inequality.
But I would argue that further than Assert.assertEquals(), Assert.assertNotEquals() works but is not user friendly to document what the test actually asserts and to understand/debug as the assertion fails.
So yes JUnit 4.11 and JUnit 5 provides Assert.assertNotEquals() (Assertions.assertNotEquals() in JUnit 5) but I really avoid using them.

As alternative, to assert the state of an object I general use a matcher API that digs into the object state easily, that document clearly the intention of the assertions and that is very user friendly to understand the cause of the assertion failure.

Here is an example.
Suppose I have an Animal class which I want to test the createWithNewNameAndAge() method, a method that creates a new Animal object by changing its name and its age but by keeping its favorite food.
Suppose I use Assert.assertNotEquals() to assert that the original and the new objects are different.
Here is the Animal class with a flawed implementation of createWithNewNameAndAge() :

public class Animal {

    private String name;
    private int age;
    private String favoriteFood;

    public Animal(String name, int age, String favoriteFood) {
        this.name = name;
        this.age = age;
        this.favoriteFood = favoriteFood;
    }

    // Flawed implementation : use this.name and this.age to create the 
    // new Animal instead of using the name and age parameters
    public Animal createWithNewNameAndAge(String name, int age) {
        return new Animal(this.name, this.age, this.favoriteFood);
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public String getFavoriteFood() {
        return favoriteFood;
    }

    @Override
    public String toString() {
        return "Animal [name=" + name + ", age=" + age + ", favoriteFood=" + favoriteFood + "]";
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + age;
        result = prime * result + ((favoriteFood == null) ? 0 : favoriteFood.hashCode());
        result = prime * result + ((name == null) ? 0 : name.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (!(obj instanceof Animal)) return false;

        Animal other = (Animal) obj;
        return age == other.age && favoriteFood.equals(other.favoriteFood) &&
                name.equals(other.name);
    }

}

JUnit 4.11+ (or JUnit 5) both as test runner and assertion tool

@Test
void assertListNotEquals_JUnit_way() {
    Animal scoubi = new Animal("scoubi", 10, "hay");
    Animal littleScoubi = scoubi.createWithNewNameAndAge("little scoubi", 1);
    Assert.assertNotEquals(scoubi, littleScoubi);
}

The test fails as expected but the cause provided to the developer is really not helpful. It just says that the values should be different and output the toString() result invoked on the actual Animal parameter :

java.lang.AssertionError: Values should be different. Actual: Animal

[name=scoubi, age=10, favoriteFood=hay]

at org.junit.Assert.fail(Assert.java:88)

Ok the objects are not equals. But where is the problem ?
Which field is not correctly valued in the tested method ? One ? Two ? All of them ?
To discover it you have to dig in the createWithNewNameAndAge() implementation/use a debugger while the testing API would be much more friendly if it would make for us the differential between which is expected and which is gotten.

JUnit 4.11 as test runner and a test Matcher API as assertion tool

Here the same scenario of test but that uses AssertJ (an excellent test matcher API) to make the assertion of the Animal state: :

import org.assertj.core.api.Assertions;

@Test
void assertListNotEquals_AssertJ() {
    Animal scoubi = new Animal("scoubi", 10, "hay");
    Animal littleScoubi = scoubi.createWithNewNameAndAge("little scoubi", 1);
    Assertions.assertThat(littleScoubi)
              .extracting(Animal::getName, Animal::getAge, Animal::getFavoriteFood)
              .containsExactly("little scoubi", 1, "hay");
}

Of course the test still fails but this time the reason is clearly stated :

java.lang.AssertionError:

Expecting:

<["scoubi", 10, "hay"]>

to contain exactly (and in same order):

<["little scoubi", 1, "hay"]>

but some elements were not found:

<["little scoubi", 1]>

and others were not expected:

<["scoubi", 10]>

at junit5.MyTest.assertListNotEquals_AssertJ(MyTest.java:26)

We can read that for Animal::getName, Animal::getAge, Animal::getFavoriteFood values of the returned Animal, we expect to have these value :

"little scoubi", 1, "hay" 

but we have had these values :

"scoubi", 10, "hay"

So we know where investigate : name and age are not correctly valued. Additionally, the fact of specifying the hay value in the assertion of Animal::getFavoriteFood() allows also to more finely assert the returned Animal. We want that the objects be not the same for some properties but not necessarily for every properties.
So definitely, using a matcher API is much more clear and flexible.

Add below setting to .eslintrc.js / .eslintrc.json to ignore these errors:

  rules: {
    // suppress errors for missing 'import React' in files
   "react/react-in-jsx-scope": "off",
    // allow jsx syntax in js files (for next.js project)
   "react/jsx-filename-extension": [1, { "extensions": [".js", ".jsx"] }], //should add ".ts" if typescript project
  }

Why? If you're using NEXT.js then you do not require to import React at top of files, nextjs does that for you.

Did you restart the server after you changed the config file?

Can you telnet to the server from a different machine?

Can you telnet to the server from the server itself?

telnet <ip address> 80

telnet localhost 80

In my case, I was using React.ReactNode as a type for a functional component instead of React.FC type.

In this component to be exact:

export const PropertiesList: React.FC = (props: any) => {_x000D_
  const list:string[] = [_x000D_
    ' Consequat Phasellus sollicitudin.',_x000D_
    ' Consequat Phasellus sollicitudin.',_x000D_
    '...'_x000D_
  ]_x000D_
_x000D_
  return (_x000D_
    <List_x000D_
      header={<ListHeader heading="Properties List" />}_x000D_
      dataSource={list}_x000D_
        renderItem={(listItem, index) =>_x000D_
          <List.Item key={index}> {listItem } </List.Item>_x000D_
      }_x000D_
    />_x000D_
  )_x000D_
}

Hopefully it will help new beginners

If you dont have keystore than use before command else skip

Generating a signing key / Keystore file You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

$ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

you will get a file like my-release-key.keystore

Setting up gradle variables Place the my-release-key.keystore file under the android/app directory in your project folder. Edit the file android/gradle.properties and add the following (replace ***** with the correct keystore password, alias and key password), enableAapt2 set false is workaround , as android gradle version 3.0 problem

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=*****
MYAPP_RELEASE_KEY_PASSWORD=*****

android.enableAapt2=false

then add these app/buid.gradle (app)

below default config

signingConfigs {
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword MYAPP_RELEASE_STORE_PASSWORD
                keyAlias MYAPP_RELEASE_KEY_ALIAS
                keyPassword MYAPP_RELEASE_KEY_PASSWORD
            }
        }

and Inside Build type release { }

 signingConfig signingConfigs.release

then simply run this command in android studio terminal Below commands will automate above all answers

if windows

cd android
gradlew assembleRelease

if linux / mac

$ cd android
$ ./gradlew assembleRelease

if you got any error delete all build folder and run command

gradlew clean

than again

gradlew assembleRelease

Try the following:

echo a#b#c | awk -F"#" '{$1 = ""; $NF = ""; print}' OFS=""

Step 1: create a MANIFEST.in file in the same folder with setup.py

Step 2: include the relative path to the files you want to add in MANIFEST.in

include README.rst
include docs/*.txt
include funniest/data.json

Step 3: set include_package_data=True in the setup() function to copy these files to site-package

Following steps has fixed my issue.

(1) Moved the website to a Dedicated application pool.

(2) Changed the Managed Pipeline Mode from integrated to Classic.

(3) Set Enable 32-Bit Applications from false to true.

I did some research on this by using different methods to assign values to a nullable int. Here is what happened when I did various things. Should clarify what's going on. Keep in mind: Nullable<something> or the shorthand something? is a struct for which the compiler seems to be doing a lot of work to let us use with null as if it were a class.
As you'll see below, SomeNullable == null and SomeNullable.HasValue will always return an expected true or false. Although not demonstrated below, SomeNullable == 3 is valid too (assuming SomeNullable is an int?).
While SomeNullable.Value gets us a runtime error if we assigned null to SomeNullable. This is in fact the only case where nullables could cause us a problem, thanks to a combination of overloaded operators, overloaded object.Equals(obj) method, and compiler optimization and monkey business.

Here is a description of some code I ran, and what output it produced in labels:

int? val = null;
lbl_Val.Text = val.ToString(); //Produced an empty string.
lbl_ValVal.Text = val.Value.ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValEqNull.Text = (val == null).ToString(); //Produced "True" (without the quotes)
lbl_ValNEqNull.Text = (val != null).ToString(); //Produced "False"
lbl_ValHasVal.Text = val.HasValue.ToString(); //Produced "False"
lbl_NValHasVal.Text = (!(val.HasValue)).ToString(); //Produced "True"
lbl_ValValEqNull.Text = (val.Value == null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValValNEqNull.Text = (val.Value != null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")

Ok, lets try the next initialization method:

int? val = new int?();
lbl_Val.Text = val.ToString(); //Produced an empty string.
lbl_ValVal.Text = val.Value.ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValEqNull.Text = (val == null).ToString(); //Produced "True" (without the quotes)
lbl_ValNEqNull.Text = (val != null).ToString(); //Produced "False"
lbl_ValHasVal.Text = val.HasValue.ToString(); //Produced "False"
lbl_NValHasVal.Text = (!(val.HasValue)).ToString(); //Produced "True"
lbl_ValValEqNull.Text = (val.Value == null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValValNEqNull.Text = (val.Value != null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")

All the same as before. Keep in mind that initializing with int? val = new int?(null);, with null passed to the constructor, would have produced a COMPILE time error, since the nullable object's VALUE is NOT nullable. It is only the wrapper object itself that can equal null.

Likewise, we would get a compile time error from:

int? val = new int?();
val.Value = null;

not to mention that val.Value is a read-only property anyway, meaning we can't even use something like:

val.Value = 3;

but again, polymorphous overloaded implicit conversion operators let us do:

val = 3;

No need to worry about polysomthing whatchamacallits though, so long as it works right? :)

You could use pandas plot as @Bharath suggest:

import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)

Output:

Updated:

from matplotlib.colors import ListedColormap df.set_index('App')\ .reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\ .T.plot(kind='bar', stacked=True, colormap=ListedColormap(sns.color_palette("GnBu", 10)), figsize=(12,6))

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

df.set_index('App')\
  .reindex(df.set_index('App').sum().sort_values().index, axis=1)\
  .T.plot(kind='bar', stacked=True,
          colormap=ListedColormap(sns.color_palette("GnBu", 10)), 
          figsize=(12,6))

Output:

This has changed for Visual Studio 2012 (I know the original question says VS2010, but the title will still hit on searches).

When you create a VS2012 MVC project, the system.web.mvc is placed in the packages folder which is peer to the solution. This will be referenced in the web project by default and you can find the exact path there).

If you want to reference this in a secondary project (say a supporting .dll with filters or other attributes), then you can reference it from there.

If you want to give the permission to the group,

sudo chmod g+w .git -R

worked best for me.

For MacOS

sudo chmod -R g+w .git 

EDIT: don't use vc80 / Visual Studio 2005, but Visual Studio 2008 / vc90 versions of the CGAL library (maybe from here).

Linker Tools Warning LNK4099:

You could also compile with /Z7, so the pdb doesn't need to be used, or remove the /DEBUG linker option if you do not have .pdb files for the objects you are linking.

You're in replace mode. Press the Insert key on your keyboard to switch back to insert mode. Many applications that handle text have this in common.

Don't know if this is too late but you can use np.where to find the indices of non values as such:

indices = list(np.where(df['b'].isna()[0]))

Inspired from @Aqua Answer.....

in Objective C

- (UIImage *)fixImageOrientation:(UIImage *)img {

   UIGraphicsBeginImageContext(img.size);
   [img drawAtPoint:CGPointZero];

   UIImage *newImg = UIGraphicsGetImageFromCurrentImageContext();
   UIGraphicsEndImageContext();

   if (newImg) {
       return newImg;
   }

   return img;
}

This issue is because of you having some local or private packages. For accessing those packages you have to create .npmrc file for this issue. Just refer the following link for your solution. https://nodesource.com/blog/configuring-your-npmrc-for-an-optimal-node-js-environment

There is a solution which only uses Bash built-ins called wildcards:

var="    abc    "
# remove leading whitespace characters
var="${var#"${var%%[![:space:]]*}"}"
# remove trailing whitespace characters
var="${var%"${var##*[![:space:]]}"}"   
printf '%s' "===$var==="

Here's the same wrapped in a function:

trim() {
    local var="$*"
    # remove leading whitespace characters
    var="${var#"${var%%[![:space:]]*}"}"
    # remove trailing whitespace characters
    var="${var%"${var##*[![:space:]]}"}"   
    printf '%s' "$var"
}

You pass the string to be trimmed in quoted form. e.g.:

trim "   abc   "

A nice thing about this solution is that it will work with any POSIX-compliant shell.

original answer by @yurzui won't work startring from Angular 9 due to - strange problem migrating angular 8 app to 9. However, you can still benefit from ngVar directive by having it and using it like

<ng-template [ngVar]="variable">
your code
</ng-template>

although it could result in IDE warning: "variable is not defined"

Most of the given examples assume that for the test range [$a..$b], $a <= $b, i.e. the range extremes are in lower - higher order and most assume that all are integer numbers.
But I needed a function to test if $n was between $a and $b, as described here:

Check if $n is between $a and $b even if:
    $a < $b  
    $a > $b
    $a = $b

All numbers can be real, not only integer.

There is an easy way to test.
I base the test it in the fact that ($n-$a) and ($n-$b) have different signs when $n is between $a and $b, and the same sign when $n is outside the $a..$b range.
This function is valid for testing increasing, decreasing, positive and negative numbers, not limited to test only integer numbers.

function between($n, $a, $b)
{
    return (($a==$n)&&($b==$n))? true : ($n-$a)*($n-$b)<0;
}

There are many way to do the string aggregation, but the easiest is a user defined function. Try this for a way that does not require a function. As a note, there is no simple way without the function.

This is the shortest route without a custom function: (it uses the ROW_NUMBER() and SYS_CONNECT_BY_PATH functions )

SELECT questionid,
       LTRIM(MAX(SYS_CONNECT_BY_PATH(elementid,','))
       KEEP (DENSE_RANK LAST ORDER BY curr),',') AS elements
FROM   (SELECT questionid,
               elementid,
               ROW_NUMBER() OVER (PARTITION BY questionid ORDER BY elementid) AS curr,
               ROW_NUMBER() OVER (PARTITION BY questionid ORDER BY elementid) -1 AS prev
        FROM   emp)
GROUP BY questionid
CONNECT BY prev = PRIOR curr AND questionid = PRIOR questionid
START WITH curr = 1;

Call me simple but I just declared a Variant and split the responsetext from my REST GET on the quote comma quote between each item, then got the value I wanted by looking for the last quote with InStrRev. I'm sure that's not as elegant as some of the other suggestions but it works for me.

         varLines = Split(.responsetext, """,""")
        strType = Mid(varLines(8), InStrRev(varLines(8), """") + 1)

You can also use guava's CharMatcher.removeFrom function.

Example:

 String s = CharMatcher.is('a').removeFrom("bazaar");

Here's the result I finally ended up using. It's a modified version of the classes by dgorissen above.

To use the pool

from random import randrange
from time import sleep

delays = [randrange(1, 10) for i in range(30)]

def wait_delay(d):
    print('sleeping for (%d)sec' % d)
    sleep(d)

pool = ThreadPool(20)
for i, d in enumerate(delays):
    pool.add_task(wait_delay, d)
pool.wait_completion()

It should be:

int a = arr.length;

Parenthesis should be avoided.

Here is an example of the wget script in action:

wget -q -O /dev/null "http://example.com/cronjob.php" > /dev/null 2>&1

Using -O parameter like the above means that the output of the web request will be sent to STDOUT (standard output).

And the >/dev/null 2>&1 will instruct standard output to be redirected to a black hole. So no message from the executing program is returned to the screen.

I was running a job which ran a shell script in Jenkins on a Windows machine. The job was failing due to the error given below. I was able to fix the error thanks to clues in Andrejz's answer.

Solution :

1 - Install Cygwin and note the directory where it gets installed.

It was C:\cygwin64 in my case. The sh.exe which is needed to run shell scripts is in the "bin" sub-directory, i.e. C:\cygwin64\bin.

2 - Tell Jenkins where sh.exe is located.

Jenkins web console > Manage Jenkins > Configure System > Under shell, set the "Shell executable" = C:\cygwin64\bin\sh.exe > Click apply & also click save.

That's all I did to make my job pass. I was running Jenkins from a war file and I did not need to restart it to make this work.

Running console svn cleanup has solved the same problem for me.

As far that I know you only can get time with Date.

Date.now is the solution but is not available everywhere : https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/now.

var currentTime = +new Date();

This gives you the current time in milliseconds.

For your jumps. If you compute interpolations correctly according to the delta frame time and you don't have some rounding number error, I bet for the garbage collector (GC).

If there is a lot of created temporary object in your loop, garbage collection has to lock the thread to make some cleanup and memory re-organization.

With Chrome you can see how much time the GC is spending in the Timeline panel.

EDIT: Since my answer, Date.now() should be considered as the best option as it is supported everywhere and on IE >= 9.

I recently discovered an interesting trick that allows to "Split String With String As Delimiter", so I couldn't resist the temptation to post it here as a new answer. Note that "obviously the question wasn't accurate. Firstly, both string1 and string2 can contain spaces. Secondly, both string1 and string2 can contain ampersands ('&')". This method correctly works with the new specifications (posted as a comment below Stephan's answer).

@echo off
setlocal

set "str=string1&with spaces by string2&with spaces.txt"

set "string1=%str: by =" & set "string2=%"
set "string2=%string2:.txt=%"

echo "%string1%"
echo "%string2%"

For further details on the split method, see this post.

Have you considered mmap()? You can read from the file directly as if it were already in memory.

http://beej.us/guide/bgipc/output/html/multipage/mmap.html

You can try it. hope it will be useful.

SELECT * FROM `table` WHERE `Value` COLLATE latin1_general_cs = "IAreSavage"

I see a lot of answers here that have you subtracting from the width of the div and/or using box-sizing, but all you need to do is apply the padding the child elements of the div in question. So, for example, if you have some markup like this:

<div id="container">
    <p id="text">Find Agents</p>
</div>

All you need to do is apply this CSS:

#text {
    padding: 10px;
}

Here is a fiddle showing the difference: http://jsfiddle.net/CHCVF/2/

Or, better yet, if you have multiple elements and don't feel like giving them all the same class, you can do something like this:

.container * {
    padding: 5px 10px;
}

Which will select all of the child elements and assign them the padding you want. Here is a fiddle of that in action: http://jsfiddle.net/CHCVF/3/

Is it simply that static is for static functions of structs and enums, and class for classes and protocols?

That's the main difference. Some other differences are that class functions are dynamically dispatched and can be overridden by subclasses.

Protocols use the class keyword, but it doesn't exclude structs from implementing the protocol, they just use static instead. Class was chosen for protocols so there wouldn't have to be a third keyword to represent static or class.

From Chris Lattner on this topic:

We considered unifying the syntax (e.g. using "type" as the keyword), but that doesn't actually simply things. The keywords "class" and "static" are good for familiarity and are quite descriptive (once you understand how + methods work), and open the door for potentially adding truly static methods to classes. The primary weirdness of this model is that protocols have to pick a keyword (and we chose "class"), but on balance it is the right tradeoff.

And here's a snippet that shows some of the override behavior of class functions:

class MyClass {
    class func myFunc() {
        println("myClass")
    }
}

class MyOtherClass: MyClass {
    override class func myFunc() {
        println("myOtherClass")
    }
}

var x: MyClass = MyOtherClass()
x.dynamicType.myFunc() //myOtherClass
x = MyClass()
x.dynamicType.myFunc() //myClass

I depends heavily on which number formats you aim to support, and how strict you want to enforce number grouping, use of whitespace and other separators etc....

Take a look at this similar question to get some ideas.

Then there is E.164 which is a numbering standard recommendation from ITU-T

Yesterday Date in PHP:

echo date("Y-m-d", strtotime("yesterday")); 

There is no variable included for that yet, so you have to use shell-out-read-file method:

sh 'pwd > workspace'
workspace = readFile('workspace').trim()

Or (if running on master node):

workspace = pwd()

You can use an XMLHttpRequest to load a page into a div (or any other element of your page really). An exemple function would be:

function loadPage(){
if (window.XMLHttpRequest){
    // code for IE7+, Firefox, Chrome, Opera, Safari
    xmlhttp=new XMLHttpRequest();
}else{
    // code for IE6, IE5
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}

xmlhttp.onreadystatechange=function(){
    if (xmlhttp.readyState==4 && xmlhttp.status==200){
        document.getElementById("ID OF ELEMENT YOU WANT TO LOAD PAGE IN").innerHTML=xmlhttp.responseText;
    }
}

xmlhttp.open("POST","WEBPAGE YOU WANT TO LOAD",true);
xmlhttp.send();
}

If your sever is capable, you could also use PHP to do this, but since you're asking for an HTML5 method, this should be all you need.

I solved this problem when it was showing on VSCode and JetBrains Terminals, but not in the native terminal using the following commands:

ls -la /usr/local/bin | grep "np[mx]"

This will give you the resolved path at the end:

... npm -> ../lib/node_modules/npm/bin/npm-cli.js
... npx -> ../lib/node_modules/npm/bin/npx-cli.js

From there, removing the files and relaunching VS Code should fix the issue:

rm -R /usr/local/bin/npm /usr/local/lib/node_modules/npm/bin/npm-cli.js
rm -R /usr/local/bin/npx /usr/local/lib/node_modules/npm/bin/npx-cli.js

Do Like this

1st put all your HTML content to array, then do json_encode

$html_content="<p>hello this is sample text";
$json_array=array(

'content'=>50,
'html_content'=>$html_content
);
echo json_encode($json_array);

Try this, it works for me if you also need to support ios7, it is based on the transparency of UItoolBar:

[self.navigationController.navigationBar setBackgroundImage:[UIImage new]
                                                  forBarMetrics:UIBarMetricsDefault];
    self.navigationController.navigationBar.shadowImage = [UIImage new];
    self.navigationController.navigationBar.translucent = YES;
    self.navigationController.view.backgroundColor = [UIColor clearColor];
    UIToolbar* blurredView = [[UIToolbar alloc] initWithFrame:self.navigationController.navigationBar.bounds];
    [blurredView setBarStyle:UIBarStyleBlack];
    [blurredView setBarTintColor:[UIColor redColor]];
    [self.navigationController.navigationBar insertSubview:blurredView atIndex:0];

Just include #xxx in your commit message to reference an issue without closing it.

With new GitHub issues 2.0 you can use these synonyms to reference an issue and close it (in your commit message):

• fix #xxx
• fixes #xxx
• fixed #xxx
• close #xxx
• closes #xxx
• closed #xxx
• resolve #xxx
• resolves #xxx
• resolved #xxx

You can also substitute #xxx with gh-xxx.

Referencing and closing issues across repos also works:

fixes user/repo#xxx

Check out the documentation available in their Help section.

I was unable to find a solution that was neatly portable between Mac OS Catalina, Ubuntu 16 and Centos 7, so I decided to do it with python inline and it worked well for my bash scripts.

to_abs_path() {
  python -c "import os; print os.path.abspath('$1')"
}

to_abs_path "/some_path/../secrets"

jQuery Mobile >= 1.4

Create a custom class, e.g. .custom-btn. Note that to override jQM styles without using !important, CSS hierarchy should be respected. .ui-btn.custom-class or .ui-input-btn.custom-class.

.ui-input-btn.custom-btn {
   border:1px solid red;
   text-decoration:none;
   font-family:helvetica;
   color:red;
   background:url(img.png) repeat-x;
}

Add a data-wrapper-class to input. The custom class will be added to input wrapping div.

<input type="button" data-wrapper-class="custom-btn">

Demo

jQuery Mobile <= 1.3

Input button is wrapped by a DIV with class ui-btn. You need to select that div and the input[type="submit"]. Using !important is essential to override Jquery Mobile styles.

Demo

div.ui-btn, input[type="submit"] {
 border:1px solid red !important;
 text-decoration:none !important;
 font-family:helvetica !important;
 color:red !important;
 background:url(../images/btn_hover.png) repeat-x !important;
}

If you are using Angular 8+ and you want to reduce the size of the bundle you can use Ivy. Ivy comes as the default view engine in Angular 9 Just go to src/tsconfig.app.json and add the angularCompilerOptions parameter, for example:

{
  "extends": ...,
  "compilerOptions":...,
  "exclude": ...,

/* add this one */ 
  "angularCompilerOptions": {
    "enableIvy": true
  }
}

Microsoft replace SWITCH, IFS and IFVALUES with CHOOSE only function.

=CHOOSE($L$1,"index_1","Index_2","Index_3")

For SQL Server

newid()/order by will work, but will be very expensive for large result sets because it has to generate an id for every row, and then sort them.

TABLESAMPLE() is good from a performance standpoint, but you will get clumping of results (all rows on a page will be returned).

For a better performing true random sample, the best way is to filter out rows randomly. I found the following code sample in the SQL Server Books Online article Limiting Results Sets by Using TABLESAMPLE:

If you really want a random sample of individual rows, modify your query to filter out rows randomly, instead of using TABLESAMPLE. For example, the following query uses the NEWID function to return approximately one percent of the rows of the Sales.SalesOrderDetail table:

SELECT * FROM Sales.SalesOrderDetail
WHERE 0.01 >= CAST(CHECKSUM(NEWID(),SalesOrderID) & 0x7fffffff AS float)
              / CAST (0x7fffffff AS int)

The SalesOrderID column is included in the CHECKSUM expression so that NEWID() evaluates once per row to achieve sampling on a per-row basis. The expression CAST(CHECKSUM(NEWID(), SalesOrderID) & 0x7fffffff AS float / CAST (0x7fffffff AS int) evaluates to a random float value between 0 and 1.

When run against a table with 1,000,000 rows, here are my results:

SET STATISTICS TIME ON
SET STATISTICS IO ON

/* newid()
   rows returned: 10000
   logical reads: 3359
   CPU time: 3312 ms
   elapsed time = 3359 ms
*/
SELECT TOP 1 PERCENT Number
FROM Numbers
ORDER BY newid()

/* TABLESAMPLE
   rows returned: 9269 (varies)
   logical reads: 32
   CPU time: 0 ms
   elapsed time: 5 ms
*/
SELECT Number
FROM Numbers
TABLESAMPLE (1 PERCENT)

/* Filter
   rows returned: 9994 (varies)
   logical reads: 3359
   CPU time: 641 ms
   elapsed time: 627 ms
*/    
SELECT Number
FROM Numbers
WHERE 0.01 >= CAST(CHECKSUM(NEWID(), Number) & 0x7fffffff AS float) 
              / CAST (0x7fffffff AS int)

SET STATISTICS IO OFF
SET STATISTICS TIME OFF

If you can get away with using TABLESAMPLE, it will give you the best performance. Otherwise use the newid()/filter method. newid()/order by should be last resort if you have a large result set.

Something else you can do, if you want to preserve your scroll position is this:

<asp:LinkButton runat="server" id="someId" href="javascript: void;" Text="Click Me" />

On apache page: http://hc.apache.org/httpcomponents-client-ga/tutorial/html/fundamentals.html

You have something like this:

URIBuilder builder = new URIBuilder();
builder.setScheme("http").setHost("www.google.com").setPath("/search")
    .setParameter("q", "httpclient")
    .setParameter("btnG", "Google Search")
    .setParameter("aq", "f")
    .setParameter("oq", "");
URI uri = builder.build();
HttpGet httpget = new HttpGet(uri);
System.out.println(httpget.getURI());

private Toolbar toolbar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    toolbar = (Toolbar) findViewById(R.id.my_toolbar);
    *// here is where you set it to show on the toolbar*
    setSupportActionBar(toolbar);
}

Well, you need to set support action bar setSupportActionBar(); and pass your variable, like so: setSupportActionBar(toolbar);

Using anytime package:

library(anytime)

anydate("2009-01")
# [1] "2009-01-01"

For Hadoop 3.x, if you try to create a file on HDFS when unauthenticated (e.g. user=dr.who) you will get this error.

It is not recommended for systems that need to be secure, however if you'd like to disable file permissions entirely in Hadoop 3 the hdfs-site.xml setting has changed to:

<property>
  <name>dfs.permissions.enabled</name>
  <value>false</value>
</property>

In the 6.6.8 version I installed the NppAutoIndent plugin from Plugins > Plugin Manager > Show Plugin Manager. Then I selected the Smart Indent option in Plugin > NppAutoIndent. Hope this helps.

After speaking with an LDAP expert, it's not possible this way. One query can't search more than one DC or OU.

Your options are:

1. Run more then 1 query and parse the result.
2. Use a filter to find the desired users/objects based off a different attribute like an AD group or by name.

SVN is one repo and lots of clients. Git is a repo with lots of client repos, each with a user. It's decentralised to a point where people can track their own edits locally without having to push things to an external server.

SVN is designed to be more central where Git is based on each user having their own Git repo and those repos push changes back up into a central one. For that reason, Git gives individuals better local version control.

Meanwhile you have the choice between TortoiseGit, GitExtensions (and if you host your "central" git-repository on github, their own client – GitHub for Windows).

If you're looking on getting out of SVN, you might want to evaluate Bazaar for a bit. It's one of the next generation of version control systems that have this distributed element. It isn't POSIX dependant like git so there are native Windows builds and it has some powerful open source brands backing it.

But you might not even need these sorts of features yet. Have a look at the features, advantages and disadvantages of the distributed VCSes. If you need more than SVN offers, consider one. If you don't, you might want to stick with SVN's (currently) superior desktop integration.

I suggest you use a wrapper div or paragraph:

<td><p style="width:50%;">Text only allowed to extend 50% of the cell.</p></td>

And you can make a class out of it:

<td class="linebreak"><p>Text only allowed to extend 50% of the cell.</p></td>

td.linebreak p {
    width: 50%;
}

All of this assuming that you meant 50% as in 50% of the cell.

You can use either commands:

1)
> svn info | awk '/Revision:/ { print $2 }' =>returns the latest version


2)
> svn log -l 1 | grep '^r[0-9]\+' | awk '{print $1}'

svn log -l 1     => returns the latest version commit 
grep '^r[0-9]\+' => greps the r4324 (revision) number
awk '{print $1}' => prints the match found

You can check the socket.connected property:

var socket = io.connect();
console.log('check 1', socket.connected);
socket.on('connect', function() {
  console.log('check 2', socket.connected);
});

It's updated dynamically, if the connection is lost it'll be set to false until the client picks up the connection again. So easy to check for with setInterval or something like that.

Another solution would be to catch disconnect events and track the status yourself.

There is one good reason you would need to style a <br> tag.

When it is part of code you don't want to (or can't) change and you want this particular <br> not to be displayed.

.xxx br {display:none}

Can save a lot of time and sometimes your day.

Instructions

First, insert these lines wherever you want within your newsletter code. Then:

1. Change "INSERT URL" to whatever website holds the shared content.
2. Change "INSERT TITLE" to the title of the article.
3. Change "INSERT SUMMARY" to a short summary of the article.
4. Change "INSERT IMAGE URL" to an image that will be shared with the rest of the content.
5. Change "INSERT DOMAIN NAME" to your domain name.
6. Change "INSERT PUBLISHERID" to your publisher ID (if you have an account, if not, remove "[INSERT PUBLISHERID]" or sign up!)

If you are using this on an email newsletter, make sure you add our sharing buttons to the destination page. This will ensure that you get complete sharing analytics for your page. Make sure you replace "INSERT PUBLISHERID" with your own.

Here is an example of how you can generate and read data from a matrix m x n... in JavaScript

let createMatrix = (m, n) => {
      let [row, column] = [[], []],
          rowColumn = m * n
      for (let i = 1; i <= rowColumn; i++) {
        column.push(i)
        if (i % n === 0) {
          row.push(column)
          column = []
        }
      }
      return row
    }

let setColorForEachElement = (matrix, colors) => {
  let row = matrix.map(row => {
    let column = row.map((column, key) => {
      return { number: column, color: colors[key] }
    })
    return column
  })
  return row
} 

const colors = ['red', 'green', 'blue', 'purple', 'brown', 'yellow', 'orange', 'grey']
const matrix = createMatrix(6, 8)
const colorApi = setColorForEachElement(matrix, colors)

let table ='<table>'
colorApi.forEach(row => {
  table+= '<tr>'
    row.forEach(column =>  table += `<td style='background: ${column.color};'>${column.number}<td>` )
  table+='</tr>'
})
table+= '</table>'
document.write(table);

You can use lynx with -stdin and -dump options to achieve that:

<?php

   0 => array("pipe", "r"),  // stdin is a pipe that the child will read from
   1 => array("pipe", "w"),  // stdout is a pipe that the child will write to
   2 => array("file", "/tmp/htmp2txt.log", "a") // stderr is a file to write to
);

$process = proc_open('lynx -stdin -dump 2>&1', $descriptorspec, $pipes, '/tmp', NULL);

if (is_resource($process)) {
    // $pipes now looks like this:
    // 0 => writeable handle connected to child stdin
    // 1 => readable handle connected to child stdout
    // Any error output will be appended to htmp2txt.log

    $stdin = $pipes[0];
    fwrite($stdin,  <<<'EOT'

    fclose($pipes[1]);

    // It is important that you close any pipes before calling
    // proc_close in order to avoid a deadlock
    $return_value = proc_close($process);

    echo "command returned $return_value\n";
}

You can use also in the php file like this

<?php ini_set('upload_max_filesize', '200M'); ?>

Use public property of child form

frmOptions {
     public string Result; }

frmMain {
     frmOptions.ShowDialog(); string r = frmOptions.Result; }

Use events

frmMain {
     frmOptions.OnResult += new ResultEventHandler(frmMain.frmOptions_Resukt);
     frmOptions.ShowDialog(); }

Use public property of main form

frmOptions {
     public frmMain MainForm; MainForm.Result = "result"; }

frmMain {
     public string Result;
     frmOptions.MainForm = this;
     frmOptions.ShowDialog();
     string r = this.Result; }

Use object Control.Tag; This is common for all controls public property which can contains a System.Object. You can hold there string or MyClass or MainForm - anything!

frmOptions {
     this.Tag = "result": }
frmMain {
     frmOptions.ShowDialog();
     string r = frmOptions.Tag as string; }

>>> item = set([0,1,2,3,4,5,6,7,8,9])
>>> z = set([2,3,4])
>>> print item - z
set([0, 1, 5, 6, 7, 8, 9])

I tried with one column of string values with nan.

To remove the nan and fill the empty string:

df.columnname.replace(np.nan,'',regex = True)

To remove the nan and fill some values:

df.columnname.replace(np.nan,'value',regex = True)

I tried df.iloc also. but it needs the index of the column. so you need to look into the table again. simply the above method reduced one step.

I'm using:

$($('form').prop('elements')).each(function(){
    console.info(this)
});

It Seems ugly, but to me it is still the better way to get all the elements with jQuery.

you can also add comment by pressing Ctrl+shift+/ and shift+ / for one line.

Look at it this way - is it more efficient to throw out the kitchen garbage when the garbage can is at 10% or let it fill up before taking it out?

By not letting it fill up, you are wasting your time walking to and from the garbage bin outside. This analogous to what happens when the GC thread runs - all the managed threads are suspended while it is running. And If I am not mistaken, the GC thread can be shared among multiple AppDomains, so garbage collection affects all of them.

Of course, you might encounter a situation where you won't be adding anything to the garbage can anytime soon - say, if you're going to take a vacation. Then, it would be a good idea to throw out the trash before going out.

This MIGHT be one time that forcing a GC can help - if your program idles, the memory in use is not garbage-collected because there are no allocations.

Yes, it is 128, except for temp tables, whose names can only be up to 116 character long. It is perfectly explained here.

And the verification can be easily made with the following script contained in the blog post before:

DECLARE @i NVARCHAR(800)
SELECT @i = REPLICATE('A', 116)
SELECT @i = 'CREATE TABLE #'+@i+'(i int)'
PRINT @i
EXEC(@i)

So my solution to my own problem: After playing around with redis-cli a bit longer I found out that DEBUG OBJECT <key> reveals something like the serializedlength of key, which was in fact something I was looking for...

For a whole database you need to aggregate all values for KEYS * which shouldn't be too difficult with a scripting language of your choice...

The bad thing is that redis.io doesn't really have a lot of information about DEBUG OBJECT.

This will return both the beginning of the week and the end of the week dates:

    private string[] GetWeekRange(DateTime dateToCheck)
    {
        string[] result = new string[2];
        TimeSpan duration = new TimeSpan(0, 0, 0, 0); //One day 
        DateTime dateRangeBegin = dateToCheck;
        DateTime dateRangeEnd = DateTime.Today.Add(duration);

        dateRangeBegin = dateToCheck.AddDays(-(int)dateToCheck.DayOfWeek);
        dateRangeEnd = dateToCheck.AddDays(6 - (int)dateToCheck.DayOfWeek);

        result[0] = dateRangeBegin.Date.ToString();
        result[1] = dateRangeEnd.Date.ToString();
        return result;

    }

I have posted the complete code for calculating the begin/end of week, month, quarter and year on my blog ZamirsBlog

from Object import Object

or

From Class_Name import Class_name

If Object is a .py file.

Here is an example of how to time a function using timeit:

import timeit

def time_this(n):
    return [str(i) for i in range(n)]

timeit.timeit(lambda: time_this(n=5000), number=1000)

This will return the time in seconds it took to execute the time_this() function 1000 times.

Starting in Numpy 1.20, the sliding_window_view provides a way to slide/roll through windows of elements. Windows that you can then individually average.

For instance, for a 4-element window:

from numpy.lib.stride_tricks import sliding_window_view

# values = np.array([5, 3, 8, 10, 2, 1, 5, 1, 0, 2])
np.average(sliding_window_view(values, window_shape = 4), axis=1)
# array([6.5, 5.75, 5.25, 4.5, 2.25, 1.75, 2])

Note the intermediary result of sliding_window_view:

# values = np.array([5, 3, 8, 10, 2, 1, 5, 1, 0, 2])
sliding_window_view(values, window_shape = 4)
# array([[ 5,  3,  8, 10],
#        [ 3,  8, 10,  2],
#        [ 8, 10,  2,  1],
#        [10,  2,  1,  5],
#        [ 2,  1,  5,  1],
#        [ 1,  5,  1,  0],
#        [ 5,  1,  0,  2]])

I needed to "set a variable if undefined" in several places. I created a function using @Alnitak answer. Hopefully it helps someone.

function setDefaultVal(value, defaultValue){
   return (value === undefined) ? defaultValue : value;
}  

Usage:

hasPoints = setDefaultVal(this.hasPoints, true);

You can use the usual Python package structure to divide your App into multiple modules, see the Flask docs.

However,

Flask uses a concept of blueprints for making application components and supporting common patterns within an application or across applications.

You can create a sub-component of your app as a Blueprint in a separate file:

simple_page = Blueprint('simple_page', __name__, template_folder='templates')
@simple_page.route('/<page>')
def show(page):
    # stuff

And then use it in the main part:

from yourapplication.simple_page import simple_page

app = Flask(__name__)
app.register_blueprint(simple_page)

Blueprints can also bundle specific resources: templates or static files. Please refer to the Flask docs for all the details.

#dimScreen{
 position:fixed;
 top:0px;
 left:0px;
 width:100%;
 height:100%;
}

You can also request for access programmatically, which I prefer because in most cases you need to know if you took the access or not.

Swift 4 update:

    //Camera
    AVCaptureDevice.requestAccess(for: AVMediaType.video) { response in
        if response {
            //access granted
        } else {

        }
    }

    //Photos
    let photos = PHPhotoLibrary.authorizationStatus()
    if photos == .notDetermined {
        PHPhotoLibrary.requestAuthorization({status in
            if status == .authorized{
                ...
            } else {}
        })
    }

You do not share code so I cannot be sure if this would be useful for you, but general speaking use it as a best practice.

If you do not need the original list of dictionaries, you could modify it in-place with sort() method using a custom key function.

Key function:

def get_name(d):
    """ Return the value of a key in a dictionary. """

    return d["name"]

The list to be sorted:

data_one = [{'name': 'Homer', 'age': 39}, {'name': 'Bart', 'age': 10}]

Sorting it in-place:

data_one.sort(key=get_name)

If you need the original list, call the sorted() function passing it the list and the key function, then assign the returned sorted list to a new variable:

data_two = [{'name': 'Homer', 'age': 39}, {'name': 'Bart', 'age': 10}]
new_data = sorted(data_two, key=get_name)

Printing data_one and new_data.

>>> print(data_one)
[{'name': 'Bart', 'age': 10}, {'name': 'Homer', 'age': 39}]
>>> print(new_data)
[{'name': 'Bart', 'age': 10}, {'name': 'Homer', 'age': 39}]

Note the "" at the beginning and at the end!

Run a program and pass a Long Filename

cmd /c write.exe "c:\sample documents\sample.txt"

Spaces in Program Path

cmd /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""

Spaces in Program Path + parameters with spaces

cmd /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""

Launch Demo1 and then Launch Demo2

cmd /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

I tried all the above solutions. but it didn't work.

The solution was to restart eclipse !!!!!!!

hope this will help someone :)

edit to my previous answer: if you want to count a function's invocations, you might want to try:

var countMe = ( function() {
  var c = 0;

  return function() {
    c++;
    return c;
  }
})();

alert(countMe()); // Alerts "1"
alert(countMe()); // Alerts "2"

Here, c serves as the counter, and you do not have to use arguments.callee.

You can use the PHP string function parse_str() followed by foreach loop.

$str="pg_id=2&parent_id=2&document&video";
parse_str($str,$my_arr);
foreach($my_arr as $key=>$value){
  echo "$key => $value<br>";
}
print_r($my_arr);

If you want get all parents key of a node in a literal object ({}), you can to do that:

(function ($) {
    "use strict";

    $.defineProperties($, {
        parentKeys: {
            value: function (object) {
                var
                    traces = [],
                    queue = [{trace: [], node: object}],

                    block = function () {
                        var
                            node,
                            nodeKeys,
                            trace;

                        // clean the queue
                        queue = [];
                        return function (map) {
                            node = map.node;
                            nodeKeys = Object.keys(node);

                            nodeKeys.forEach(function (nodeKey) {
                                if (typeof node[nodeKey] == "object") {
                                    trace = map.trace.concat(nodeKey);
                                    // put on queue
                                    queue.push({trace: trace, node: node[nodeKey]});

                                    // traces.unshift(trace);
                                    traces.push(trace);
                                }
                            });
                        };
                    };

                while(true) {
                    if (queue.length) {
                        queue.forEach(block());
                    } else {
                        break;
                    }
                }

                return traces;
            },

            writable: true
        }

    });

})(Object);

This algorithm uses the FIFO concept for iterate the graphs using the BFS method. This code extend the class Object adding the static method parentKeys that expects a literal Object (hash table - associative array...) of the Javacript, as parameter.

I hope I have helped.

I had the same problem here... I tried to use destroy() and clear() method, but without success.

I resolved it the next way:

HTML:

<div id="pieChartContent">
    <canvas id="pieChart" width="300" height="300"></canvas>
</div>

Javascript:

var pieChartContent = document.getElementById('pieChartContent');
pieChartContent.innerHTML = ' ';
$('#pieChartContent').append('<canvas id="pieChart" width="300" height="300"><canvas>');

ctx = $("#pieChart").get(0).getContext("2d");        
var myPieChart = new Chart(ctx).Pie(data, options);

It works perfect to me... I hope that It helps.

There are also these 'ways':

>>> dict.fromkeys(range(1, 4))
{1: None, 2: None, 3: None}
>>> dict(zip(range(1, 4), range(1, 4)))
{1: 1, 2: 2, 3: 3}

I would recommend using CSS for this. You should create a CSS rule to enforce the centering, for example:

.ui-helper-center {
    text-align: center;
}

And then add the ui-helper-center class to the table cells for which you wish to control the alignment:

<td class="ui-helper-center">Content</td>

EDIT: Since this answer was accepted, I felt obligated to edit out the parts that caused a flame-war in the comments, and to not promote poor and outdated practices.

See Gabe's answer for how to include the CSS rule into your page.

REST stands for REpresentational State Transfer and goes a little something like this:

We have a bunch of uniquely addressable 'entities' that we want made available via a web application. Those entities each have some identifier and can be accessed in various formats. REST defines a bunch of stuff about what GET, POST, etc mean for these purposes.

the basic idea with REST is that you can attach a bunch of 'renderers' to different entities so that they can be available in different formats easily using the same HTTP verbs and url formats.

For more clarification on what RESTful means and how it is used google rails. Rails is a RESTful framework so there's loads of good information available in its docs and associated blog posts. Worth a read even if you arent keen to use the framework. For example: http://www.sitepoint.com/restful-rails-part-i/

RESTless means not restful. If you have a web app that does not adhere to RESTful principles then it is not RESTful

Set to cookie in the main domain -

document.cookie = "key=value;domain=.mydomain.com"

and then take the data from any main domain or sub domain and set it on the localStorage

I implemented something like this, using pickle for persistance and using sha1 for short almost-certainly-unique IDs. Basically the cache hashed the code of the function and the hist of arguments to get a sha1 then looked for a file with that sha1 in the name. If it existed, it opened it and returned the result; if not, it calls the function and saves the result (optionally only saving if it took a certain amount of time to process).

That said, I'd swear I found an existing module that did this and find myself here trying to find that module... The closest I can find is this, which looks about right: http://chase-seibert.github.io/blog/2011/11/23/pythondjango-disk-based-caching-decorator.html

The only problem I see with that is it wouldn't work well for large inputs since it hashes str(arg), which isn't unique for giant arrays.

It would be nice if there were a unique_hash() protocol that had a class return a secure hash of its contents. I basically manually implemented that for the types I cared about.

I found that you don't necessarily need the text vertically centred, it also looks good near the bottom of the row, it's only when it's at the top (or above centre?) that it looks wrong. So I went with this to push the links to the bottom of the row:

.navbar-brand {
    min-height: 80px;
}

@media (min-width: 768px) {
    #navbar-collapse {
        position: absolute;
        bottom: 0px;
        left: 250px;
    }
}

My brand image is SVG and I used height: 50px; width: auto which makes it about 216px wide. It spilled out of its container vertically so I added the min-height: 80px; to make room for it plus bootstrap's 15px margins. Then I tweaked the navbar-collapse's left setting until it looked right.

Using Node.js

sync mode:

var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")

async mode:

var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
    var textByLine = text.split("\n")
});

UPDATE

As of at least Node 6, readFileSync returns a Buffer, so it must first be converted to a string in order for split to work:

var text = fs.readFileSync("./mytext.txt").toString('utf-8');

Or

var text = fs.readFileSync("./mytext.txt", "utf-8");

" Hello " , " This " , "is ", "Sorting ", "Example"

First of all you provided spaces in " Hello " and " This ", spaces have a lower value than alphabetic characters in Unicode, so it gets printed first. (The rest of the characters were sorted alphabetically).

Now upper case letters have a lower value than lower case letter in Unicode, so "Example" and "Sorting" gets printed, then at last "is " which has the highest value.

With the suggestions @jhadesdev and the explanations from others, I've found the issue here.

After adding the code to see what was visible to the various class loaders I found this:

All versions of log4j Logger: 
  zip:<snip>war/WEB-INF/lib/log4j-1.2.17.jar!/org/apache/log4j/Logger.class

All versions of log4j visible from the classloader of the OAuthAuthorizer class: 
  zip:<snip>war/WEB-INF/lib/log4j-1.2.17.jar!/org/apache/log4j/Logger.class

All versions of XMLConfigurator:

  zip:<snip>war/WEB-INF/lib/ipp-java-aggcat-v1-devkit-1.0.2.jar!/org/opensaml/xml/XMLConfigurator.class
  zip:<snip>war/WEB-INF/lib/xmltooling-1.3.1.jar!/org/opensaml/xml/XMLConfigurator.class

All versions of XMLConfigurator visible from the classloader of the OAuthAuthorizer class: 
  jar:<snip>com.bea.core.bea.opensaml2_1.0.0.0_6-1-0-0.jar!/org/opensaml/xml/XMLConfigurator.class
  zip:<snip>war/WEB-INF/lib/ipp-java-aggcat-v1-devkit-1.0.2.jar!/org/opensaml/xml/XMLConfigurator.class
  zip:<snip>war/WEB-INF/lib/xmltooling-1.3.1.jar!/org/opensaml/xml/XMLConfigurator.class

I noticed that another version of XMLConfigurator was possibly getting picked up. I decompiled that class and found this at line 60 (where the error was in the original stack trace) private static final Logger log = Logger.getLogger(XMLConfigurator.class); and that class was importing from org.apache.log4j.Logger!

So it was this class that was being loaded and used. My fix was to rename the jar file that contained this file as I can't find where I explicitly or indirectly load it. Which may pose a problem when I actually deploy.

Thanks for all help and the much needed lesson on class loading.

If you need more than 1 class

You can do this:

<i id="icon" 
  v-bind:class="{ 'fa fa-star': showStar }"
  v-on:click="showStar = !showStar"

  showStar: true
}

Notice the single quotes ' around the classes!

Thanks to everyone else's solutions.

This post is old, but I change your code to:

scope.$watch("assignments", function (value) {//I change here
  var val = value || null;            
  if (val)
    element.dataTable({"bDestroy": true});
  });
}

CASE in MySQL is both a statement and an expression, where each usage is slightly different.

As a statement, CASE works much like a switch statement and is useful in stored procedures, as shown in this example from the documentation (linked above):

DELIMITER |

CREATE PROCEDURE p()
  BEGIN
    DECLARE v INT DEFAULT 1;

    CASE v
      WHEN 2 THEN SELECT v;
      WHEN 3 THEN SELECT 0;
      ELSE
        BEGIN -- Do other stuff
        END;
    END CASE;
  END;
  |

However, as an expression it can be used in clauses:

SELECT *
  FROM employees
  ORDER BY
    CASE title
      WHEN "President" THEN 1
      WHEN "Manager" THEN 2
      ELSE 3
    END, surname

Additionally, both as a statement and as an expression, the first argument can be omitted and each WHEN must take a condition.

SELECT *
  FROM employees
  ORDER BY
    CASE 
      WHEN title = "President" THEN 1
      WHEN title = "Manager" THEN 2
      ELSE 3
    END, surname

I provided this answer because the other answer fails to mention that CASE can function both as a statement and as an expression. The major difference between them is that the statement form ends with END CASE and the expression form ends with just END.

You are right. If you want to delete the User and all associated objects -> destroy_all However, if you just want to delete the User without suppressing all associated objects -> delete_all

According to this post : Rails :dependent => :destroy VS :dependent => :delete_all

• destroy / destroy_all: The associated objects are destroyed alongside this object by calling their destroy method
• delete / delete_all: All associated objects are destroyed immediately without calling their :destroy method

What about invoke-item script.bat.

If you want create a new branch from any of the existing branches in Git, just follow the options.

First change/checkout into the branch from where you want to create a new branch. For example, if you have the following branches like:

• master
• dev
• branch1

So if you want to create a new branch called "subbranch_of_b1" under the branch named "branch1" follow the steps:

1. Checkout or change into "branch1"

   git checkout branch1
   

2. Now create your new branch called "subbranch_of_b1" under the "branch1" using the following command.

   git checkout -b subbranch_of_b1 branch1
   

   The above will create a new branch called subbranch_of_b1 under the branch branch1 (note that branch1 in the above command isn't mandatory since the HEAD is currently pointing to it, you can precise it if you are on a different branch though).

3. Now after working with the subbranch_of_b1 you can commit and push or merge it locally or remotely.

push the subbranch_of_b1 to remote

 git push origin subbranch_of_b1 

There is also a property resourceRef of JndiObjectFactoryBean that is, when set to true, used to automatically prepend the string java:comp/env/ if it is not already present.

The System.Math.Round method uses the Double structure, which, as others have pointed out, is prone to floating point precision errors. The simple solution I found to this problem when I encountered it was to use the System.Decimal.Round method, which doesn't suffer from the same problem and doesn't require redifining your variables as decimals:

Decimal.Round(0.575, 2, MidpointRounding.AwayFromZero)

Result: 0.58

No, filter does not scan the whole stream. It's an intermediate operation, which returns a lazy stream (actually all intermediate operations return a lazy stream). To convince you, you can simply do the following test:

List<Integer> list = Arrays.asList(1, 10, 3, 7, 5);
int a = list.stream()
            .peek(num -> System.out.println("will filter " + num))
            .filter(x -> x > 5)
            .findFirst()
            .get();
System.out.println(a);

Which outputs:

will filter 1
will filter 10
10

You see that only the two first elements of the stream are actually processed.

So you can go with your approach which is perfectly fine.

If you really want to use String:

NSString *number = [[NSString alloc] initWithFormat:@"%d", 123];

But I would recommend using NSNumber:

NSNumber *number = [[NSNumber alloc] initWithInt:123];

Then just add it to the array.

[array addObject:number];

Don't forget to release it after that, since you created it above.

[number release];

maybe this can help..

SELECT constraint_name, constraint_type, column_name
from user_constraints natural join user_cons_columns
where table_name = "my_table_name";

If you want separate values for sides and top-bottom.

<table style="border-spacing: 5px 10px;">

One of #a or #b needs to be not position:absolute, so that #box will grow to accommodate it.

So you can stop #a from being position:absolute, and still position #b over the top of it, like this:

 #box {_x000D_
        background-color: #000;_x000D_
        position: relative;     _x000D_
        padding: 10px;_x000D_
        width: 220px;_x000D_
    }_x000D_
    _x000D_
    .a {_x000D_
        width: 210px;_x000D_
        background-color: #fff;_x000D_
        padding: 5px;_x000D_
    }_x000D_
    _x000D_
    .b {_x000D_
        width: 100px; /* So you can see the other one */_x000D_
        position: absolute;_x000D_
        top: 10px; left: 10px;_x000D_
        background-color: red;_x000D_
        padding: 5px;_x000D_
    }_x000D_
    _x000D_
    #after {_x000D_
        background-color: yellow;_x000D_
        padding: 10px;_x000D_
        width: 220px;_x000D_
    }

    <div id="box">_x000D_
        <div class="a">Lorem</div>_x000D_
        <div class="b">Lorem</div>_x000D_
    </div>_x000D_
    <div id="after">Hello world</div>

(Note that I've made the widths different, so you can see one behind the other.)

Edit after Justine's comment: Then your only option is to specify the height of #box. This:

#box {
    /* ... */
    height: 30px;
}

works perfectly, assuming the heights of a and b are fixed. Note that you'll need to put IE into standards mode by adding a doctype at the top of your HTML

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
          "http://www.w3.org/TR/html4/strict.dtd">

before that works properly.

Remember: import UIKit

Swift:

UIDevice.currentDevice().name

Swift 3, 4, 5:

UIDevice.current.name

#include <iostream>
#include <string>
using namespace std;

int main()
{
    cout << stod("  99.999  ") << endl;
}

Output: 99.999 (which is double, whitespace was automatically stripped)

Since C++11 converting string to floating-point values (like double) is available with functions:
stof - convert str to a float
stod - convert str to a double
stold - convert str to a long double

I want a function that returns 0 when the string is not numerical.

You can add try catch statement when stod throws an exception.

create a pair of client / server, so that after the execution, client server sends the correct time and date. Then, the client asks the server pm GMT and the server sends back the answer right.

If it can help someone, we have struggled a lot with Assetic, and we are now doing the following in development mode:

• Set up like in Dumping Asset Files in the dev Environmen so in config_dev.yml, we have commented:

  #assetic:
  #    use_controller: true
  

  And in routing_dev.yml

  #_assetic:
  #    resource: .
  #    type:     assetic
  

• Specify the URL as absolute from the web root. For example, background-image: url("/bundles/core/dynatree/skins/skin/vline.gif"); Note: our vhost web root is pointing on web/.

• No usage of cssrewrite filter

No need for jQuery. And it isn't necessary to open a new window. Protocols which doesn't return HTTP data to the browser (mailto:, irc://, magnet:, ftp:// (<- it depends how it is implemented, normally the browser has an FTP client built in)) can be queried in the same window without losing the current content. In your case:

function redirect()
{
    window.location.href = "mailto:[email protected]";
}
<body onload="javascript: redirect();">

Or just directly

<body onload="javascript: window.location.href='mailto:[email protected]';">

I think the only way to handle this is to use JavaScript

Try this Invert text color of a specific element

If you do this with css3 it's only compatible with the newest browser versions.

U can setup AVPlayer in another way, that open for u full customization of your video Player screen

Swift 2.3

1. Create UIView subclass for playing video (basically u can use any UIView object and only needed is AVPlayerLayer. I setup in this way because it much clearer for me)

   import AVFoundation
   import UIKit
   
   class PlayerView: UIView {
   
   override class func layerClass() -> AnyClass {
       return AVPlayerLayer.self
   }
   
   var player:AVPlayer? {
       set {
           if let layer = layer as? AVPlayerLayer {
               layer.player = player
           }
       }
       get {
           if let layer = layer as? AVPlayerLayer {
               return layer.player
           } else {
               return nil
           }
       }
   }
   }

Whilst I'm sure POCO means Plain Old Class Object or Plain Old C Object to 99.9% of people here, POCO is also Animator Pro's (Autodesk) built in scripting language.

You could use the function trim

let str = ' Hello World ';

alert (str.trim());

All the front and back spaces around Hello World would be removed.

I'm using XAMPP 1.6.7 on Windows 7. This article worked for me.

I added the following lines in the file httpd-vhosts.conf at C:/xampp/apache/conf/extra.
I had also uncommented the line # NameVirtualHost *:80

<VirtualHost mysite.dev:80>
    DocumentRoot "C:/xampp/htdocs/mysite"
    ServerName mysite.dev
    ServerAlias mysite.dev
    <Directory "C:/xampp/htdocs/mysite">
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

After restarting the apache, it were still not working. Then I had to follow the step 9 mentioned in the article by editing the file C:/Windows/System32/drivers/etc/hosts.

# localhost name resolution is handled within DNS itself.
     127.0.0.1       localhost
     ::1             localhost
     127.0.0.1       mysite.dev  

Then I got working http://mysite.dev

Building on the previous answers (pun intended), an excellent real-world example is Groovy's built in support for Builders.

• Creating XML using Groovy's MarkupBuilder
• Creating XML using Groovy's StreamingMarkupBuilder
• Swing Builder
• SwingXBuilder

See Builders in the Groovy Documentation

Late to the party, but the OP should have gone with Buildout or Virtualenv, and sidestepped the problem completely.

I am currently working on a Centos server, well, toiling away would be the proper term and I can assure everyone that the only way I am able to blink back the tears whilst using the software equivalents of fire hardened spears, is buildout.

git reflog is your friend. Find the commit that you want to be on in that list and you can reset to it (for example:git reset --hard e870e41).

(If you didn't commit your changes... you might be in trouble - commit early, and commit often!)

As Richard said, StringWriter is the way forward. There's one snag, however: by default, StringWriter will advertise itself as being in UTF-16. Usually XML is in UTF-8. You can fix this by subclassing StringWriter;

public class Utf8StringWriter : StringWriter
{
    public override Encoding Encoding
    {
         get { return Encoding.UTF8; }
    }
}

This will affect the declaration written by XmlWriter. Of course, if you then write the string out elsewhere in binary form, make sure you use an encoding which matches whichever encoding you fix for the StringWriter. (The above code always assumes UTF-8; it's trivial to make a more general version which accepts an encoding in the constructor.)

You'd then use:

using (TextWriter writer = new Utf8StringWriter())
{
    using (XmlWriter xmlWriter = XmlWriter.Create(writer))
    {
        ...
    }
    return writer.ToString();
}

You can try using jQuery with the Attribute Contains Prefix Selector.

$('[id|=q1_]')

Haven't tested it though.

Return all checked element in the radio button

  Array.from(document.getElementsByClassName("className")).filter(x=>x['checked']);

First you retreieve the value (given a key) and then you add a new element to it

    ArrayList<String> grades = examList.get(courseId);
    grades.add(aGrade);

TL;DR

If you have any doubt, use merge.

Short Answer

The only differences between a rebase and a merge are:

• The resulting tree structure of the history (generally only noticeable when looking at a commit graph) is different (one will have branches, the other won't).
• Merge will generally create an extra commit (e.g. node in the tree).
• Merge and rebase will handle conflicts differently. Rebase will present conflicts one commit at a time where merge will present them all at once.

So the short answer is to pick rebase or merge based on what you want your history to look like.

Long Answer

There are a few factors you should consider when choosing which operation to use.

Is the branch you are getting changes from shared with other developers outside your team (e.g. open source, public)?

If so, don't rebase. Rebase destroys the branch and those developers will have broken/inconsistent repositories unless they use git pull --rebase. This is a good way to upset other developers quickly.

How skilled is your development team?

Rebase is a destructive operation. That means, if you do not apply it correctly, you could lose committed work and/or break the consistency of other developer's repositories.

I've worked on teams where the developers all came from a time when companies could afford dedicated staff to deal with branching and merging. Those developers don't know much about Git and don't want to know much. In these teams I wouldn't risk recommending rebasing for any reason.

Does the branch itself represent useful information

Some teams use the branch-per-feature model where each branch represents a feature (or bugfix, or sub-feature, etc.) In this model the branch helps identify sets of related commits. For example, one can quickly revert a feature by reverting the merge of that branch (to be fair, this is a rare operation). Or diff a feature by comparing two branches (more common). Rebase would destroy the branch and this would not be straightforward.

I've also worked on teams that used the branch-per-developer model (we've all been there). In this case the branch itself doesn't convey any additional information (the commit already has the author). There would be no harm in rebasing.

Might you want to revert the merge for any reason?

Reverting (as in undoing) a rebase is considerably difficult and/or impossible (if the rebase had conflicts) compared to reverting a merge. If you think there is a chance you will want to revert then use merge.

Do you work on a team? If so, are you willing to take an all or nothing approach on this branch?

Rebase operations need to be pulled with a corresponding git pull --rebase. If you are working by yourself you may be able to remember which you should use at the appropriate time. If you are working on a team this will be very difficult to coordinate. This is why most rebase workflows recommend using rebase for all merges (and git pull --rebase for all pulls).

Common Myths

Merge destroys history (squashes commits)

Assuming you have the following merge:

    B -- C
   /      \
  A--------D

Some people will state that the merge "destroys" the commit history because if you were to look at the log of only the master branch (A -- D) you would miss the important commit messages contained in B and C.

If this were true we wouldn't have questions like this. Basically, you will see B and C unless you explicitly ask not to see them (using --first-parent). This is very easy to try for yourself.

Rebase allows for safer/simpler merges

The two approaches merge differently, but it is not clear that one is always better than the other and it may depend on the developer workflow. For example, if a developer tends to commit regularly (e.g. maybe they commit twice a day as they transition from work to home) then there could be a lot of commits for a given branch. Many of those commits might not look anything like the final product (I tend to refactor my approach once or twice per feature). If someone else was working on a related area of code and they tried to rebase my changes it could be a fairly tedious operation.

Rebase is cooler / sexier / more professional

If you like to alias rm to rm -rf to "save time" then maybe rebase is for you.

My Two Cents

I always think that someday I will come across a scenario where Git rebase is the awesome tool that solves the problem. Much like I think I will come across a scenario where Git reflog is an awesome tool that solves my problem. I have worked with Git for over five years now. It hasn't happened.

Messy histories have never really been a problem for me. I don't ever just read my commit history like an exciting novel. A majority of the time I need a history I am going to use Git blame or Git bisect anyway. In that case, having the merge commit is actually useful to me, because if the merge introduced the issue, that is meaningful information to me.

Update (4/2017)

I feel obligated to mention that I have personally softened on using rebase although my general advice still stands. I have recently been interacting a lot with the Angular 2 Material project. They have used rebase to keep a very clean commit history. This has allowed me to very easily see what commit fixed a given defect and whether or not that commit was included in a release. It serves as a great example of using rebase correctly.

^{A sample command that exhibits the symptom: sed 's/./@/' <<<$'\xfc' fails, because byte 0xfc is not a valid UTF-8 char.
Note that, by contrast, GNU sed (Linux, but also installable on macOS) simply passes the invalid byte through, without reporting an error.}

Using the formerly accepted answer is an option if you don't mind losing support for your true locale (if you're on a US system and you never need to deal with foreign characters, that may be fine.)

However, the same effect can be had ad-hoc for a single command only:

LC_ALL=C sed -i "" 's|"iphoneos-cross","llvm-gcc:-O3|"iphoneos-cross","clang:-Os|g' Configure

Note: What matters is an effective LC_CTYPE setting of C, so LC_CTYPE=C sed ... would normally also work, but if LC_ALL happens to be set (to something other than C), it will override individual LC_*-category variables such as LC_CTYPE. Thus, the most robust approach is to set LC_ALL.

However, (effectively) setting LC_CTYPE to C treats strings as if each byte were its own character (no interpretation based on encoding rules is performed), with no regard for the - multibyte-on-demand - UTF-8 encoding that OS X employs by default, where foreign characters have multibyte encodings.

In a nutshell: setting LC_CTYPE to C causes the shell and utilities to only recognize basic English letters as letters (the ones in the 7-bit ASCII range), so that foreign chars. will not be treated as letters, causing, for instance, upper-/lowercase conversions to fail.

Again, this may be fine if you needn't match multibyte-encoded characters such as é, and simply want to pass such characters through.

If this is insufficient and/or you want to understand the cause of the original error (including determining what input bytes caused the problem) and perform encoding conversions on demand, read on below.

The problem is that the input file's encoding does not match the shell's.
More specifically, the input file contains characters encoded in a way that is not valid in UTF-8 (as @Klas Lindbäck stated in a comment) - that's what the sed error message is trying to say by invalid byte sequence.

Most likely, your input file uses a single-byte 8-bit encoding such as ISO-8859-1, frequently used to encode "Western European" languages.

Example:

The accented letter à has Unicode codepoint 0xE0 (224) - the same as in ISO-8859-1. However, due to the nature of UTF-8 encoding, this single codepoint is represented as 2 bytes - 0xC3 0xA0, whereas trying to pass the single byte 0xE0 is invalid under UTF-8.

Here's a demonstration of the problem using the string voilà encoded as ISO-8859-1, with the à represented as one byte (via an ANSI-C-quoted bash string ($'...') that uses \x{e0} to create the byte):

Note that the sed command is effectively a no-op that simply passes the input through, but we need it to provoke the error:

  # -> 'illegal byte sequence': byte 0xE0 is not a valid char.
sed 's/.*/&/' <<<$'voil\x{e0}'

To simply ignore the problem, the above LCTYPE=C approach can be used:

  # No error, bytes are passed through ('á' will render as '?', though).
LC_CTYPE=C sed 's/.*/&/' <<<$'voil\x{e0}'

If you want to determine which parts of the input cause the problem, try the following:

  # Convert bytes in the 8-bit range (high bit set) to hex. representation.
  # -> 'voil\x{e0}'
iconv -f ASCII --byte-subst='\x{%02x}' <<<$'voil\x{e0}'

The output will show you all bytes that have the high bit set (bytes that exceed the 7-bit ASCII range) in hexadecimal form. (Note, however, that that also includes correctly encoded UTF-8 multibyte sequences - a more sophisticated approach would be needed to specifically identify invalid-in-UTF-8 bytes.)

Performing encoding conversions on demand:

Standard utility iconv can be used to convert to (-t) and/or from (-f) encodings; iconv -l lists all supported ones.

Examples:

Convert FROM ISO-8859-1 to the encoding in effect in the shell (based on LC_CTYPE, which is UTF-8-based by default), building on the above example:

  # Converts to UTF-8; output renders correctly as 'voilà'
sed 's/.*/&/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')"

Note that this conversion allows you to properly match foreign characters:

  # Correctly matches 'à' and replaces it with 'ü': -> 'voilü'
sed 's/à/ü/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')"

To convert the input BACK to ISO-8859-1 after processing, simply pipe the result to another iconv command:

sed 's/à/ü/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')" | iconv -t ISO-8859-1

Result Set are actually contains multiple rows of data, and use a cursor to point out current position. So in your case, rs4.getString(1) only get you the data in first column of first row. In order to change to next row, you need to call next()

a quick example

while (rs.next()) {
    String sid = rs.getString(1);
    String lid = rs.getString(2);
    // Do whatever you want to do with these 2 values
}

there are many useful method in ResultSet, you should take a look :)

There are several options. If performance is a concern, test them to see which works fastest in a large loop.

double Adjust(double input)
{
    double whole = Math.Truncate(input);
    double remainder = input - whole;
    if (remainder < 0.3)
    {
        remainder = 0;
    }
    else if (remainder < 0.8)
    {
        remainder = 0.5;
    }
    else
    {
        remainder = 1;
    }
    return whole + remainder;
}

Mac OS X doesn't store the path in .bash_profile, but .profile, since Mac OS X is a branch of *BSD family. You should be able to see the export blah blah blah in .profile once you do cat .profile on your terminal.

I was stuck with ast.literal_eval(). I was trying it in IntelliJ IDEA debugger, and it kept returning None on debugger output.

But later when I assigned its output to a variable and printed it in code. It worked fine. Sharing code example:

import ast
sample_string = '[{"id":"XYZ_GTTC_TYR", "name":"Suction"}]'
output_value = ast.literal_eval(sample_string)
print(output_value)

Its python version 3.6.

Like others, the accepted answer also gave me an outdated version.

Here is another way to do it that works very well:

$ curl --silent --location https://rpm.nodesource.com/setup_14.x | bash -
$ yum -y install nodejs

You can also replace the 14.x with another version, such as 12.x, 10.x, etc.

You can see all available versions on the NodeSource Github page, and pull from there as well if desired.

Note: you may need to run using sudo depending on your environment.

you can do this easily without manual editing or using fancy text editors. Here's a vbscript.

Set objFS = CreateObject("Scripting.FileSystemObject")
strFolder="c:\test"
Set objFolder = objFS.GetFolder(strFolder)
For Each strFile In objFolder.Files
    If objFS.GetExtensionName(strFile) = "jpg" Then    
        strFileName = strFile.Name
        If InStr(strFileName,"Vacation2010") > 0 Then           
            strNewFileName = Replace(strFileName,"Vacation2010","December")
            strFile.Name = strNewFileName
        End If 
    End If  
Next 

save as myscript.vbs and

C:\test> cscript //nologo myscript.vbs 

$myarray = array_values($myarray);

array_values

Normally Python throws NameError if the variable is not defined:

>>> d[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined

However, you've managed to stumble upon a name that already exists in Python.

Because dict is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.

The type of dict is a type. All types are objects in Python. Thus you are actually trying to index into the type object. This is why the error message says that the "'type' object is not subscriptable."

>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable

Note that you can blindly assign to the dict name, but you really don't want to do that. It's just going to cause you problems later.

>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'

The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:

d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))

i used this code to change status bar to transparent

    activity?.window?.setFlags(
        WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
        WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
    )

to change it to color in style used this code i used in fragment in onDetach()

activity?.window?.clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)

Why don't you try to grep the return of your command ? Something like :

adb devices -l | grep 123abc12

It should return only the line you want to.

if you have used curl above the page and below your html is present and unfortunately your html page is not able to view then just enable your curl. But in order to check CURL is enable or not in php you need to write following code:

echo 'Curl: ', function_exists('curl_version') ? 'Enabled' : 'Disabled';

What you want is %.2f, not 2%f.

Also, you might want to replace your %d with a %f ;)

#include <cstdio>
int main()
{
printf("When this number: %f is assigned to 2 dp, it will be: %.2f ", 94.9456, 94.9456);
return 0;
}

This will output:

When this number: 94.945600 is assigned to 2 dp, it will be: 94.95

See here for a full description of the printf formatting options: printf

If you have a variable unsigned int x;, you can convert it to an int using (int)x.

I hope this complete example will help you.

This is the TaxiInfo class which holds information about a taxi ride:

namespace Taxi.Models
{
    public class TaxiInfo
    {
        public String Driver { get; set; }
        public Double Fare { get; set; }
        public Double Distance { get; set; }
        public String StartLocation { get; set; }
        public String EndLocation { get; set; }
    }
}

We also have a convenience model which holds a List of TaxiInfo(s):

namespace Taxi.Models
{
    public class TaxiInfoSet
    {
        public List<TaxiInfo> TaxiInfoList { get; set; }

        public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
        {
            TaxiInfoList = new List<TaxiInfo>();

            foreach(var TaxiInfo in TaxiInfos)
            {
                TaxiInfoList.Add(TaxiInfo);
            }
        }
    }
}

Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:

public ActionResult Index()
{
    var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
    var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };

    return View(new TaxiInfoSet(taxi1,taxi2));
}

The code for the view is as follows:

@model Taxi.Models.TaxiInfoSet
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@foreach(var TaxiInfo in Model.TaxiInfoList){
    <form>
        <h1>Cost: [email protected]</h1>
        <h2>Distance: @(TaxiInfo.Distance) km</h2>
        <p>
            Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
        </p>
        @Html.ActionLink("Home","Booking",TaxiInfo)
    </form>
}

The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:

    public ActionResult Booking(TaxiInfo Taxi)
    {
        return View(Taxi);
    }

This returns a the following view:

@model Taxi.Models.TaxiInfo

@{
    ViewBag.Title = "Booking";
}

<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>

A visual tour:

The isConnected method won't help, it will return true even if the remote side has closed the socket. Try this:

public class MyServer {
    public static final int PORT = 12345;
    public static void main(String[] args) throws IOException, InterruptedException {
        ServerSocket ss = ServerSocketFactory.getDefault().createServerSocket(PORT);
        Socket s = ss.accept();
        Thread.sleep(5000);
        ss.close();
        s.close();
    }
}

public class MyClient {
    public static void main(String[] args) throws IOException, InterruptedException {
        Socket s = SocketFactory.getDefault().createSocket("localhost", MyServer.PORT);
        System.out.println(" connected: " + s.isConnected());
        Thread.sleep(10000);
        System.out.println(" connected: " + s.isConnected());
    }
}

Start the server, start the client. You'll see that it prints "connected: true" twice, even though the socket is closed the second time.

The only way to really find out is by reading (you'll get -1 as return value) or writing (an IOException (broken pipe) will be thrown) on the associated Input/OutputStreams.

VC++ is not actually a language but is commonly referred to like one. When VC++ is referred to as a language, it usually means Microsoft's implementation of C++, which contains various knacks that do not exist in regular C++, such as the __super keyword. It is similar to the various GNU extensions to the C language that are implemented in GCC.

If you are new to Active Directory, I suggest you should understand how Active Directory stores data first.

Active Directory is actually a LDAP server. Objects stored in LDAP server are stored hierarchically. It's very similar to you store your files in your file system. That's why it got the name Directory server and Active Directory

The containers and objects on Active Directory can be specified by a distinguished name. The distinguished name is like this CN=SomeName,CN=SomeDirectory,DC=yourdomain,DC=com. Like a traditional relational database, you can run query against a LDAP server. It's called LDAP query.

There are a number of ways to run a LDAP query in .NET. You can use DirectorySearcher from System.DirectoryServices or SearchRequest from System.DirectoryServices.Protocol.

For your question, since you are asking to find user principal object specifically, I think the most intuitive way is to use PrincipalSearcher from System.DirectoryServices.AccountManagement. You can easily find a lot of different examples from google. Here is a sample that is doing exactly what you are asking for.

using (var context = new PrincipalContext(ContextType.Domain, "yourdomain.com"))
{
    using (var searcher = new PrincipalSearcher(new UserPrincipal(context)))
    {
        foreach (var result in searcher.FindAll())
        {
            DirectoryEntry de = result.GetUnderlyingObject() as DirectoryEntry;
            Console.WriteLine("First Name: " + de.Properties["givenName"].Value);
            Console.WriteLine("Last Name : " + de.Properties["sn"].Value);
            Console.WriteLine("SAM account name   : " + de.Properties["samAccountName"].Value);
            Console.WriteLine("User principal name: " + de.Properties["userPrincipalName"].Value);
            Console.WriteLine();
        }
    }
}
Console.ReadLine();

Note that on the AD user object, there are a number of attributes. In particular, givenName will give you the First Name and sn will give you the Last Name. About the user name. I think you meant the user logon name. Note that there are two logon names on AD user object. One is samAccountName, which is also known as pre-Windows 2000 user logon name. userPrincipalName is generally used after Windows 2000.

I have a similar problem with Error:Execution failed for task ':app:mergeDebugResources. And at last I found the reason is the pictures resource error which use the incorrect ".9.png".

I'm the maintainer of Mongoose. findById() is a built-in method on Mongoose models. findById(id) is equivalent to findOne({ _id: id }), with one caveat: findById() with 0 params is equivalent to findOne({ _id: null }).

You can read more about findById() on the Mongoose docs and this findById() tutorial.

.html() only takes a string OR a function as an argument, not both. Try this:

 $("#showDiv").click(function () {
     $('#theDiv').show(1000, function () {
         setTimeout(function () {
             $('#theDiv').html(function () {
                 setTimeout(function () {
                     $('#theDiv').html('Here is some replacement text');
                 }, 0);
                 setTimeout(function () {
                     $('#theDiv').html('More replacement text goes here');
                 }, 2500);
             });
         }, 2500);
     });
 }); //click function ends

jsFiddle example

Good quote taken from a blog

The DOM component is "garbage collected", as is the JScript component, which means that if you create an object within either component, and then lose track of that object, it will eventually be cleaned up.

For example:

function makeABigObject() {
var bigArray = new Array(20000);
}

When you call that function, the JScript component creates an object (named bigArray) that is accessible within the function. As soon as the function returns, though, you "lose track" of bigArray because there's no way to refer to it anymore. Well, the JScript component realizes that you've lost track of it, and so bigArray is cleaned up--its memory is reclaimed. The same sort of thing works in the DOM component. If you say document.createElement('div'), or something similar, then the DOM component creates an object for you. Once you lose track of that object somehow, the DOM component will clean up the related.

Although it is a late answer, I would say this will help you...

$query = $this->db
              ->select('user_id, count(user_id) AS num_of_time')
              ->group_by('user_id')
              ->order_by('num_of_time', 'desc')
              ->get('tablename', 10);
print_r($query->result());

You can add a style.css, import this file after the bootstrap.css to override this code.

For example:

/* bootstrap.css */
* {
   font-size: 14px;
   line-height: 1.428;
}

/* style.css */
* {
   font-size: 16px;
   line-height: 2;
}

Don't change bootstrap.css directly for better maintenance of code.

Use the Controller's Redirect() method.

public ActionResult YourAction()
{
    // ...
    return Redirect("http://www.example.com");
}

Update

You can't directly perform a server side redirect from an ajax response. You could, however, return a JsonResult with the new url and perform the redirect with javascript.

public ActionResult YourAction()
{
    // ...
    return Json(new {url = "http://www.example.com"});
}

$.post("@Url.Action("YourAction")", function(data) {
    window.location = data.url;
});

If this is used in conjunction for INSERTING a new record you could use something like this.

(You've stated in your comments that the id is auto incrementing and the other table needs the next ID + 1)

INSERT INTO TABLE2 (id, field1, field2, field3, etc) 
VALUES(
   SELECT (MAX(id) + 1), field1, field2, field3, etc FROM TABLE1
   WHERE condition_here_if_needed
)

This is pseudocode but you get the idea

Hi please check the below link

https://www.postgresql.org/docs/current/xfunc-sql.html

EX:

CREATE FUNCTION sum_n_product_with_tab (x int)
RETURNS TABLE(sum int, product int) AS $$
    SELECT $1 + tab.y, $1 * tab.y FROM tab;
$$ LANGUAGE SQL;

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

If you want to extend the amount of time permitted for an ASP.NET script to execute then increase the Server.ScriptTimeout value. The default is 90 seconds for .NET 1.x and 110 seconds for .NET 2.0 and later.

For example:

// Increase script timeout for current page to five minutes
Server.ScriptTimeout = 300;

This value can also be configured in your web.config file in the httpRuntime configuration element:

<!-- Increase script timeout to five minutes -->
<httpRuntime executionTimeout="300" 
  ... other configuration attributes ...
/>

Please note according to the MSDN documentation:

"This time-out applies only if the debug attribute in the compilation element is False. Therefore, if the debug attribute is True, you do not have to set this attribute to a large value in order to avoid application shutdown while you are debugging."

If you've already done this but are finding that your session is expiring then increase the ASP.NET HttpSessionState.Timeout value:

For example:

// Increase session timeout to thirty minutes
Session.Timeout = 30;

This value can also be configured in your web.config file in the sessionState configuration element:

<configuration>
  <system.web>
    <sessionState 
      mode="InProc"
      cookieless="true"
      timeout="30" />
  </system.web>
</configuration>

If your script is taking several minutes to execute and there are many concurrent users then consider changing the page to an Asynchronous Page. This will increase the scalability of your application.

The other alternative, if you have administrator access to the server, is to consider this long running operation as a candidate for implementing as a scheduled task or a windows service.

To remove just a few specific files from being tracked:

git update-index --assume-unchanged path/to/file

If ever you want to start tracking it again:

git update-index --no-assume-unchanged path/to/file                      

C++03 (Source: Iterator Invalidation Rules (C++03))

Insertion

Sequence containers

• vector: all iterators and references before the point of insertion are unaffected, unless the new container size is greater than the previous capacity (in which case all iterators and references are invalidated) [23.2.4.3/1]
• deque: all iterators and references are invalidated, unless the inserted member is at an end (front or back) of the deque (in which case all iterators are invalidated, but references to elements are unaffected) [23.2.1.3/1]
• list: all iterators and references unaffected [23.2.2.3/1]

Associative containers

• [multi]{set,map}: all iterators and references unaffected [23.1.2/8]

Container adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Erasure

Sequence containers

• vector: every iterator and reference after the point of erase is invalidated [23.2.4.3/3]
• deque: all iterators and references are invalidated, unless the erased members are at an end (front or back) of the deque (in which case only iterators and references to the erased members are invalidated) [23.2.1.3/4]
• list: only the iterators and references to the erased element is invalidated [23.2.2.3/3]

Associative containers

• [multi]{set,map}: only iterators and references to the erased elements are invalidated [23.1.2/8]

Container adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Resizing

• vector: as per insert/erase [23.2.4.2/6]
• deque: as per insert/erase [23.2.1.2/1]
• list: as per insert/erase [23.2.2.2/1]

Note 1

Unless otherwise specified (either explicitly or by defining a function in terms of other functions), invoking a container member function or passing a container as an argument to a library function shall not invalidate iterators to, or change the values of, objects within that container. [23.1/11]

Note 2

It's not clear in C++2003 whether "end" iterators are subject to the above rules; you should assume, anyway, that they are (as this is the case in practice).

Note 3

The rules for invalidation of pointers are the sames as the rules for invalidation of references.

mkdir C:\VTS 2> NUL

create a folder called VTS and output A subdirectory or file TEST already exists to NUL.

or

(C:&(mkdir "C:\VTS" 2> NUL))&

change the drive letter to C:, mkdir, output error to NUL and run the next command.

Generally to count distinct values in single column, you can use Series.value_counts:

df.domain.value_counts()

#'vk.com'          5
#'twitter.com'     2
#'facebook.com'    1
#'google.com'      1
#Name: domain, dtype: int64

To see how many unique values in a column, use Series.nunique:

df.domain.nunique()
# 4

To get all these distinct values, you can use unique or drop_duplicates, the slight difference between the two functions is that unique return a numpy.array while drop_duplicates returns a pandas.Series:

df.domain.unique()
# array(["'vk.com'", "'twitter.com'", "'facebook.com'", "'google.com'"], dtype=object)

df.domain.drop_duplicates()
#0          'vk.com'
#2     'twitter.com'
#4    'facebook.com'
#6      'google.com'
#Name: domain, dtype: object

As for this specific problem, since you'd like to count distinct value with respect to another variable, besides groupby method provided by other answers here, you can also simply drop duplicates firstly and then do value_counts():

import pandas as pd
df.drop_duplicates().domain.value_counts()

# 'vk.com'          3
# 'twitter.com'     2
# 'facebook.com'    1
# 'google.com'      1
# Name: domain, dtype: int64

Foreign Key Constraint Names Have to be Unique Within a Database

Both @Dorvalla’s answer and this blog post mentioned above pointed me into the right direction to fix the problem for myself; quoting from the latter:

If the table you're trying to create includes a foreign key constraint, and you've provided your own name for that constraint, remember that it must be unique within the database.

I wasn’t aware of that. I have changed my foreign key constraint names according to the following schema which appears to be used by Ruby on Rails applications, too:

<TABLE_NAME>_<FOREIGN_KEY_COLUMN_NAME>_fk

For the OP’s table this would be Link_lession_id_fk, for example.

This should be faster than iterating and will work regardless of shape.

numpy.isnan(myarray).any()

Edit: 30x faster:

import timeit
s = 'import numpy;a = numpy.arange(10000.).reshape((100,100));a[10,10]=numpy.nan'
ms = [
    'numpy.isnan(a).any()',
    'any(numpy.isnan(x) for x in a.flatten())']
for m in ms:
    print "  %.2f s" % timeit.Timer(m, s).timeit(1000), m

Results:

  0.11 s numpy.isnan(a).any()
  3.75 s any(numpy.isnan(x) for x in a.flatten())

Bonus: it works fine for non-array NumPy types:

>>> a = numpy.float64(42.)
>>> numpy.isnan(a).any()
False
>>> a = numpy.float64(numpy.nan)
>>> numpy.isnan(a).any()
True

In Rails 5+ you can simply use the function as demonstrated below with simple example:

module ApplicationHelper
  # format datetime in the format #2018-12-01 12:12 PM
  def datetime_format(datetime = nil)
    if datetime
      datetime.strftime('%Y-%m-%d %H:%M %p')
    else
      'NA'
    end
  end
end

class ExamplesController < ApplicationController
  def index
    current_datetime = helpers.datetime_format DateTime.now
    raise current_datetime.inspect
  end
end

I think you are misinterpreting the source of the error; rExternalTotal appears to be equal to a single cell. rReportData.offset(0,0) is equal to rReportData
rReportData.offset(261,0).end(xlUp) is likely also equal to rReportData, as you offset by 261 rows and then use the .end(xlUp) function which selects the top of a contiguous data range.
If you are interested in the sum of just a column, you can just refer to the whole column:

dExternalTotal = Application.WorksheetFunction.Sum(columns("A:A"))

or

dExternalTotal = Application.WorksheetFunction.Sum(columns((rReportData.column))

The worksheet function sum will correctly ignore blank spaces.

Let me know if this helps!

I'm using this easy solution. You can just add this library with gradle: https://github.com/fernandodev/easy-rating-dialog

compile 'com.github.fernandodev.easyratingdialog:easyratingdialog:+'

For me, I just wanted to test a website that had an automatic http->https redirect. I think I had some certs installed already, so this alone works for me on Ubuntu 16.04 running curl 7.47.0 (x86_64-pc-linux-gnu) libcurl/7.47.0 GnuTLS/3.4.10 zlib/1.2.8 libidn/1.32 librtmp/2.3

curl --proto-default https <target>

You can do it using the foreach loop

DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];

  foreach(DataRow row in dr_art_line_2.Rows)
  {
     QuantityInIssueUnit_value = Convert.ToInt32(row["columnname"]);
  }

I could happen that if your array contains the string "hello", and if you are searching for "he", grep returns true, although, "he" may not be an array element.

Perhaps,

if (grep(/^$match$/, @array)) more apt.

I tend to find that if I'm specifying individual colours in multiple geom's, I'm doing it wrong. Here's how I would plot your data:

##Subset the necessary columns
dd_sub = datos[,c(20, 2,3,5)]
##Then rearrange your data frame
library(reshape2)
dd = melt(dd_sub, id=c("fecha"))

All that's left is a simple ggplot command:

ggplot(dd) + geom_line(aes(x=fecha, y=value, colour=variable)) +
  scale_colour_manual(values=c("red","green","blue"))

For Symfony 2.1 onwards for use with Twig error display I altered the function to add a FormError instead of simply retrieving them, this way you have more control over errors and do not have to use error_bubbling on each individual input. If you do not set it in the manner below {{ form_errors(form) }} will remain blank:

/**
 * @param \Symfony\Component\Form\Form $form
 *
 * @return void
 */
private function setErrorMessages(\Symfony\Component\Form\Form $form) {      

    if ($form->count() > 0) {
        foreach ($form->all() as $child) {
            if (!$child->isValid()) {
                if( isset($this->getErrorMessages($child)[0]) ) {
                    $error = new FormError( $this->getErrorMessages($child)[0] );
                    $form->addError($error);
                }
            }
        }
    }

}

Quite simple, with a * wildcard.

cp -r Folder1/* Folder2/

But according to your example recursion is not needed so the following will suffice:

cp Folder1/* Folder2/

EDIT:

Or skip the mkdir Folder2 part and just run:

cp -r Folder1 Folder2

In Java 8, the syntax for this simplifies greatly and can be used to accomplish this transformation succinctly.

Do note, you will need to change your field from a concrete implementation to the List interface for this to work smoothly.

public class Wetland {
    private String name;
    private List<String> species;
    public Wetland(String name, String[] speciesArr) {
        this.name = name;
        species = Arrays.stream(speciesArr)
                        .collect(Collectors.toList());
    }
}

You'll need the SQL Server Configuration Manager. Go to Sql Native Client Configuration, Select Client Protocols, Right Click on TCP/IP and set your default port there.

Last month I tried to configure iptables on a LXC VM container, but every time after reboot the iptables configuration was not automatically loaded.

The only way for me to get it working was by running the following command:

yum -y install iptables-services; systemctl disable firewalld; systemctl mask firewalld; service iptables restart; service iptables save

Here's an alternative way of solving this. It uses a while loop but takes into consideration empty gaps between rows.

function getLastRow (column) {
  var iLastRow = ss.getActiveSheet().getMaxRows();
  var aValues = ss.getActiveSheet().getRange(column + ":" + column).getValues();
  var row = "";
  while(row == ""){
    row = aValues[iLastRow-1];
    iLastRow--;
  }
  return iLastRow;
}

There are two different ways to use delay in selenium one which is most commonly in use. Please try this:

driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

second one which you can use that is simply try catch method by using that method you can get your desire result.if you want example code feel free to contact me defiantly I will provide related code

You need to implement the equals() method in your MyClass.

The reason that == didn't work is this is checking that they refer to the same instance. Since you did new for each, each one is a different instance.

The reason that equals() didn't work is because you didn't implement it yourself yet. I believe it's default behavior is the same thing as ==.

Note that you should also implement hashcode() if you're going to implement equals() because a lot of java.util Collections expect that.

You can use the target argument in the Thread constructor to directly pass in a function that gets called instead of run.

I also encountered the same problem but brew install python3 does not work properly to install pip3.

brre will throw the warning The post-install step did not complete successfully.

It has to do with homebrew does not have permission to /usr/local

Create the directory if not exist

sudo mkdir lib 
sudo mkdir Frameworks

Give the permissions inside /usr/local to homebrew so it can access them:

sudo chown -R $(whoami) $(brew --prefix)/*

Now ostinstall python3

brew postinstall python3

This will give you a successful installation

There is some official documentation on that point: Best Practices for Writing Dockerfiles

Because image size matters, using ADD to fetch packages from remote URLs is strongly discouraged; you should use curl or wget instead. That way you can delete the files you no longer need after they've been extracted and you won't have to add another layer in your image.

RUN mkdir -p /usr/src/things \
  && curl -SL http://example.com/big.tar.gz \
    | tar -xJC /usr/src/things \
  && make -C /usr/src/things all

For other items (files, directories) that do not require ADD’s tar auto-extraction capability, you should always use COPY.

Assuming you're getting norm from scipy.stats, you probably just need to sort your list:

import numpy as np
import scipy.stats as stats
import matplotlib.pyplot as plt

h = [186, 176, 158, 180, 186, 168, 168, 164, 178, 170, 189, 195, 172,
     187, 180, 186, 185, 168, 179, 178, 183, 179, 170, 175, 186, 159,
     161, 178, 175, 185, 175, 162, 173, 172, 177, 175, 172, 177, 180]
h.sort()
hmean = np.mean(h)
hstd = np.std(h)
pdf = stats.norm.pdf(h, hmean, hstd)
plt.plot(h, pdf) # including h here is crucial

And so I get:
