HashSet is O(1) to access elements, so it certainly does matter. But maintaining order of the objects in the set isn't possible.

TreeSet is useful if maintaining an order(In terms of values and not the insertion order) matters to you. But, as you've noted, you're trading order for slower time to access an element: O(log n) for basic operations.

From the javadocs for TreeSet:

This implementation provides guaranteed log(n) time cost for the basic operations (add, remove and contains).

You should use the = operator for string comparison:

Sourcesystem="ABC"

if [ "$Sourcesystem" = "XYZ" ]; then 
    echo "Sourcesystem Matched" 
else
    echo "Sourcesystem is NOT Matched $Sourcesystem"  
fi;

man test says that you use -z to match for empty strings.

I am reading a book (Effective Python) by Brett Slatkin and he shows another way to iterate over a list and also know the index of the current item in the list but he suggests that it is better not to use it and to use enumerate instead. I know you asked what enumerate means, but when I understood the following, I also understood how enumerate makes iterating over a list while knowing the index of the current item easier (and more readable).

list_of_letters = ['a', 'b', 'c']
for i in range(len(list_of_letters)):
    letter = list_of_letters[i]
    print (i, letter)

The output is:

0 a
1 b
2 c

I also used to do something, even sillier before I read about the enumerate function.

i = 0
for n in list_of_letters:
    print (i, n)
    i += 1

It produces the same output.

But with enumerate I just have to write:

list_of_letters = ['a', 'b', 'c']
for i, letter in enumerate(list_of_letters):
    print (i, letter)

So I have faced the same problem when trying to start apache service and I would like to share my solutions with you. Here is some notes about services or programs that may use port 80:

1. Skype: skype uses port 80/443 by default. You can change this from tools->options-> advanced->connections and disable checkbox "use port 80 and 443 for addtional incoming connections".
2. IIS: IIS uses port 80 be default so you need to shut down it. You can use the following two commands net stop w3svc net stop iisadmin
3. SQL Server Reporting Service: You need to stop this service because it may take port 80 if IIS is not running. Go to local services and stop it.

These options work great with me and I can start apache service without errors.

The other option is to change apache listen port from httpd.conf and set another port number.

Hope this solution helps anyone who face the same problem again.

You can overload the main() method, but only public static void main(String[] args) will be used when your class is launched by the JVM. For example:

public class Test {
    public static void main(String[] args) {
        System.out.println("main(String[] args)");
    }

    public static void main(String arg1) {
        System.out.println("main(String arg1)");
    }

    public static void main(String arg1, String arg2) {
        System.out.println("main(String arg1, String arg2)");
    }
}

That will always print main(String[] args) when you run java Test ... from the command line, even if you specify one or two command-line arguments.

You can call the main() method yourself from code, of course - at which point the normal overloading rules will be applied.

EDIT: Note that you can use a varargs signature, as that's equivalent from a JVM standpoint:

public static void main(String... args)

Using find and replace will work if you type "null" in the find and put a zero in the replace...you will be warned that this cannot be undone.

Yes, pretty much. List<T> is a generic class. It supports storing values of a specific type without casting to or from object (which would have incurred boxing/unboxing overhead when T is a value type in the ArrayList case). ArrayList simply stores object references. As a generic collection, List<T> implements the generic IEnumerable<T> interface and can be used easily in LINQ (without requiring any Cast or OfType call).

ArrayList belongs to the days that C# didn't have generics. It's deprecated in favor of List<T>. You shouldn't use ArrayList in new code that targets .NET >= 2.0 unless you have to interface with an old API that uses it.

There are several tricks available for aligning the elements.

01. Using Table Trick

.container{_x000D_
  display:table;_x000D_
 }_x000D_
_x000D_
.left{_x000D_
  background:green;_x000D_
  display:table-cell;_x000D_
  width:33.33vw;_x000D_
}_x000D_
_x000D_
.center{_x000D_
  background:gold;_x000D_
  display:table-cell;_x000D_
  width:33.33vw;_x000D_
}_x000D_
_x000D_
.right{_x000D_
  background:gray;_x000D_
  display:table-cell;_x000D_
  width:33.33vw;_x000D_
}

<div class="container">_x000D_
  <div class="left">_x000D_
    Left_x000D_
  </div>_x000D_
  <div class="center">_x000D_
    Center_x000D_
  </div>_x000D_
  <div class="right">_x000D_
    Right_x000D_
  </div>_x000D_
</div>

02. Using Flex Trick

.container{_x000D_
  display:flex;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
   }_x000D_
_x000D_
.left{_x000D_
  background:green;_x000D_
  width:33.33vw;_x000D_
}_x000D_
_x000D_
.center{_x000D_
  background:gold;_x000D_
   width:33.33vw;_x000D_
}_x000D_
_x000D_
.right{_x000D_
  background:gray;_x000D_
   width:33.33vw;_x000D_
}

<div class="container">_x000D_
  <div class="left">_x000D_
    Left_x000D_
  </div>_x000D_
  <div class="center">_x000D_
    Center_x000D_
  </div>_x000D_
  <div class="right">_x000D_
    Right_x000D_
  </div>_x000D_
</div>

03. Using Float Trick

.left{_x000D_
  background:green;_x000D_
  width:100px;_x000D_
  float:left;_x000D_
}_x000D_
_x000D_
.center{_x000D_
   background:gold;_x000D_
   width:100px;_x000D_
   float:left;_x000D_
}_x000D_
_x000D_
.right{_x000D_
   background:gray;_x000D_
   width:100px;_x000D_
   float:left;_x000D_
}

<div class="container">_x000D_
  <div class="left">_x000D_
    Left_x000D_
  </div>_x000D_
  <div class="center">_x000D_
    Center_x000D_
  </div>_x000D_
  <div class="right">_x000D_
    Right_x000D_
  </div>_x000D_
</div>

Just Press Alt + Command + Enter to open the Assistant editor. Assistant Editor will open up the Timeline view. Timeline by default shows your console output.

Additionally You can add any line to Timeline view by pressing the small circle next to the eye icon in the results area. This will enable history for this expression. So you can see the output of the variable over last 30 secs (you can change this as well) of execution.

You can always refer to resources in your application directly by their JNDI name as configured in the container, but if you do so, essentially you are wiring the container-specific name into your code. This has some disadvantages, for example, if you'll ever want to change the name later for some reason, you'll need to update all the references in all your applications, and then rebuild and redeploy them.

<resource-ref> introduces another layer of indirection: you specify the name you want to use in the web.xml, and, depending on the container, provide a binding in a container-specific configuration file.

So here's what happens: let's say you want to lookup the java:comp/env/jdbc/primaryDB name. The container finds that web.xml has a <resource-ref> element for jdbc/primaryDB, so it will look into the container-specific configuration, that contains something similar to the following:

<resource-ref>
  <res-ref-name>jdbc/primaryDB</res-ref-name>
  <jndi-name>jdbc/PrimaryDBInTheContainer</jndi-name>
</resource-ref>

Finally, it returns the object registered under the name of jdbc/PrimaryDBInTheContainer.

The idea is that specifying resources in the web.xml has the advantage of separating the developer role from the deployer role. In other words, as a developer, you don't have to know what your required resources are actually called in production, and as the guy deploying the application, you will have a nice list of names to map to real resources.

An easy way to split lists into rows is by floating the individual list items and then the item that you want to go to the next line you can clear the float.

for example

<li style="float: left; display: inline-block"></li>
<li style="float: left; display: inline-block"></li>
<li style="float: left; display: inline-block"></li>

<li style="float: left; display: inline-block; clear: both"></li> --- this will start on a new line
<li style="float: left; display: inline-block"></li>
<li style="float: left; display: inline-block"></li>

Because you're encapsulating the product again. Try to convert it like so:

let body = JSON.stringify(product); 

1. There's no need to call equals if hashCode differs.
2. There's no need to call hashCode if (obj1 == obj2).
3. There's no need for hashCode and/or equals just to iterate - you're not comparing objects
4. When needed to distinguish in between objects.

This is a classic problem in CSS. There's not really a solution for this.

This article from A List Apart is a good read on this problem. It uses a technique called "faux columns", based on having one vertically tiled background image on the element containing the columns that creates the illusion of equal-length columns. Since it is on the floated elements' wrapper, it is as long as the longest element.

The A List Apart editors have this note on the article:

A note from the editors: While excellent for its time, this article may not reflect modern best practices.

The technique requires completely static width designs that doesn't work well with the liquid layouts and responsive design techniques that are popular today for cross-device sites. For static width sites, however, it's a reliable option.

Using the {# #} notation, like so:

{# Everything you see here is a comment. It won't show up in the HTML output. #}

$( "#foo" ).slideUp( 300 ).delay( 5000 ).fadeIn( 400 );

In Visual Studio 2012, the same can be done using the "Sync With Active Document" option in Solution Explorer

The standard way to find the processing time in ms of a block of code in python 3.x is the following:

import datetime

t_start = datetime.datetime.now()

# Here is the python3 code, you want 
# to check the processing time of

t_end = datetime.datetime.now()
print("Time taken : ", (t_end - t_start).total_seconds()*1000, " ms")

In Python 2.6+ and 3.0+, you would use the format() string method:

for i in (1, 10, 100):
    print('{num:02d}'.format(num=i))

or using the built-in (for a single number):

print(format(i, '02d'))

See the PEP-3101 documentation for the new formatting functions.

If you use command line interface for inserting sql file to database.

Be sure your table charset utf8mb4 and column collation utf8mb4_unicode_ci or utf8mb4_bin

mysql -u root -p123456 my_database < profiles.sql

ERROR 1366 (HY000) at line 1679: Incorrect string value: '\xF0\x9F\x98\x87\xF0\x9F...' for column 'note' at row 328

we can solve the problem with this parameter --default-character-set=name (Set the default character set)

mysql -u root -p123456 --default-character-set=utf8mb4 my_database < profiles.sql

The best methods are already given but why not look at a couple of other methods for fun? Warning: these are more expensive methods but do serve in other circumstances.

The expensive regex method and the css attribute selector with starts with ^ operator

Option Explicit

Public Sub test()

    Debug.Print StartWithSubString("ab", "abc,d")

End Sub

Regex:

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft VBScript Regular Expressions
    Dim re As VBScript_RegExp_55.RegExp
    Set re = New VBScript_RegExp_55.RegExp

    re.Pattern = "^" & substring

    StartWithSubString = re.test(testString)

End Function

Css attribute selector with starts with operator

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft HTML Object Library
    Dim html As MSHTML.HTMLDocument
    Set html = New MSHTML.HTMLDocument

    html.body.innerHTML = "<div test=""" & testString & """></div>"

    StartWithSubString = html.querySelectorAll("[test^=" & substring & "]").Length > 0

End Function

I fixed it without deleting apply plugin: 'com.google.gms.google-services' I had the error Execution failed for task ':app:processDebugGoogleServices' because I was using two different versions of google services in my dependencies :

implementation "com.google.android.gms:play-services-maps:11.8.0"
implementation "com.google.android.gms:play-services-nearby:16.0.0"

I changed it to :

implementation "com.google.android.gms:play-services-maps:11.8.0"
implementation "com.google.android.gms:play-services-nearby:11.8.0"

Then it worked

Open $CATALINA_BASE/conf/web.xml and find this

<!-- ==================== Default Session Configuration ================= -->
<!-- You can set the default session timeout (in minutes) for all newly   -->
<!-- created sessions by modifying the value below.                       -->

<session-config>
  <session-timeout>30</session-timeout>
</session-config>

all webapps implicitly inherit from this default web descriptor. You can override session-config as well as other settings defined there in your web.xml.

This is actually from my Tomcat 7 (Windows) but I think 5.5 conf is not very different

In process all threads share system resource like heap Memory etc. while Thread has its own stack

So your ans should be heap memory which all threads share for a process.

In my situation, I didn't have the full vendor dependencies in place (composer file was messed up during original install) - so running any artisan commands caused a failure.

I was able to use the --no-scripts flag to prevent artisan from executing before it was included. Once my dependencies were in place, everything worked as expected.

composer update --no-scripts

The accepted answer gives me this output

# bash date.sh
Time in seconds: 51
date.sh: line 12: unexpected EOF while looking for matching `"'
date.sh: line 21: syntax error: unexpected end of file

This is how I solved the issue

#!/bin/bash

date1=$(date --date 'now' +%s) #date since epoch in seconds at the start of script
somecommand
date2=$(date --date 'now' +%s) #date since epoch in seconds at the end of script
difference=$(echo "$((date2-$date1))") # difference between two values
date3=$(echo "scale=2 ; $difference/3600" | bc) # difference/3600 = seconds in hours
echo SCRIPT TOOK $date3 HRS TO COMPLETE # 3rd variable for a pretty output.

In Python 3 this is no longer an issue, and you really don't want to use list comprehension, coercion, filters, functions or lambdas for something like this.

Just use

popped = unpopped[:-1]

Remember that it's an immutable, so you will have to reassign the value if you want it to change

my_tuple = my_tuple[:-1]

Example

>>> foo= 3,5,2,4,78,2,1
>>> foo
(3, 5, 2, 4, 78, 2, 1)
foo[:-1]
(3, 5, 2, 4, 78, 2)

Check this out: http://www.codeproject.com/KB/dotnet/MethodName.aspx

Another non-bash 4 way.

#!/bin/bash

# A pretend Python dictionary with bash 3 
ARRAY=( "cow:moo"
        "dinosaur:roar"
        "bird:chirp"
        "bash:rock" )

for animal in "${ARRAY[@]}" ; do
    KEY=${animal%%:*}
    VALUE=${animal#*:}
    printf "%s likes to %s.\n" "$KEY" "$VALUE"
done

echo -e "${ARRAY[1]%%:*} is an extinct animal which likes to ${ARRAY[1]#*:}\n"

You could throw an if statement for searching in there as well. if [[ $var =~ /blah/ ]]. or whatever.

I've found that image-buttons DO return a response, but you should NOT use a value-option. What I see returned are two version of the name="MYNAME" with .X and .Y endings.

For example:

<input type="image" src="/path-to/stop.png" name="STOP" width="25" height="25" align="top" alt="Stop sign">

This is within your <form> to </form>. If you click the image, what's returned are STOP.X and STOP.Y with numeric values. The existence of either indicates the STOP image-button was clicked. You don't need any special code. Just treat it as another kind of "submit" button that returns a pair of augmented NAMEs.

I've tried this on Safari, Firefox and Chrome. The image wasn't displayed with Safari, but where it was supposed to be located, my cursor turned into a finger-icon, and I could click it.

Private Function LoaderData(ByVal strSql As String) As DataTable
    Dim cnn As SqlConnection
    Dim dad As SqlDataAdapter

    Dim dtb As New DataTable
    cnn = New SqlConnection(My.Settings.mySqlConnectionString)
    Try
        cnn.Open()
        dad = New SqlDataAdapter(strSql, cnn)
        dad.Fill(dtb)
        cnn.Close()
        dad.Dispose()
    Catch ex As Exception
        cnn.Close()
        MsgBox(ex.Message)
    End Try
    Return dtb
End Function

I don't believe you can, though I hope that someone will prove me wrong.

I know you can print the query and its toString method will show you the sql without the replacements. That can be handy if you're building complex query strings, but it doesn't give you the full query with values.

I'll put my $0.02 in. Sometimes you wind up needing to add a "finally" later on in your code (because who ever writes their code perfectly the first time?). In those cases, suddenly it makes more sense to have the try/catch outside the loop. For example:

try {
    for(int i = 0; i < max; i++) {
        String myString = ...;
        float myNum = Float.parseFloat(myString);
        dbConnection.update("MY_FLOATS","INDEX",i,"VALUE",myNum);
    }
} catch (NumberFormatException ex) {
    return null;
} finally {
    dbConnection.release();  // Always release DB connection, even if transaction fails.
}

Because if you get an error, or not, you only want to release your database connection (or pick your favorite type of other resource...) once.

From cron manual http://man7.org/linux/man-pages/man5/crontab.5.html:

Lists are allowed. A list is a set of numbers (or ranges) separated by commas. Examples: "1,2,5,9", "0-4,8-12".

So in this case it would be:

30 10,14 * * *

It's jumping to March because today is 29th Jan, and adding a month gives 29th Feb, which doesn't exist, so it's moving to the next valid date.

This will happen on the 31st of a lot of months as well, but is obviously more noticable in the case of January to Feburary because Feb is shorter.

If you're not interested in the day of month and just want it to give the next month, you should specify the input date as the first of the current month. This will always give you the correct answer if you add a month.

For the same reason, if you want to always get the last day of the next month, you should start by calculating the first of the month after the one you want, and subtracting a day.

On ipython or jupyter notebook, you can use all the above mentioned ways, but i go with

my_func?

or

?my_func

for quick summary of both method signature and docstring.

I avoid using

my_func??

(as commented by @rohan) for docstring and use it only to check the source code

It will be faster because it doesnt have to wait for locks

I Found this the most useful and easy to use https://wiki.python.org/moin/ConfigParserExamples

You just create a "myfile.ini" like:

[SectionOne]
Status: Single
Name: Derek
Value: Yes
Age: 30
Single: True

[SectionTwo]
FavoriteColor=Green
[SectionThree]
FamilyName: Johnson

[Others]
Route: 66

And retrieve the data like:

>>> import ConfigParser
>>> Config = ConfigParser.ConfigParser()
>>> Config
<ConfigParser.ConfigParser instance at 0x00BA9B20>
>>> Config.read("myfile.ini")
['c:\\tomorrow.ini']
>>> Config.sections()
['Others', 'SectionThree', 'SectionOne', 'SectionTwo']
>>> Config.options('SectionOne')
['Status', 'Name', 'Value', 'Age', 'Single']
>>> Config.get('SectionOne', 'Status')
'Single'

$(document).click((e) => {
  if ($.contains($(".the-one-you-can-click-and-should-still-open").get(0), e.target)) {
  } else {
    this.onClose();
  }
}); 

If you want to do this via the designer you can do it by following the instructions here "Save changes is not permitted" when changing an existing column to be nullable

I located the Facebook's console buster script using Chrome developer tools. Here is the script with minor changes for readability. I have removed the bits that I could not understand:

Object.defineProperty(window, "console", {
    value: console,
    writable: false,
    configurable: false
});

var i = 0;
function showWarningAndThrow() {
    if (!i) {
        setTimeout(function () {
            console.log("%cWarning message", "font: 2em sans-serif; color: yellow; background-color: red;");
        }, 1);
        i = 1;
    }
    throw "Console is disabled";
}

var l, n = {
        set: function (o) {
            l = o;
        },
        get: function () {
            showWarningAndThrow();
            return l;
        }
    };
Object.defineProperty(console, "_commandLineAPI", n);
Object.defineProperty(console, "__commandLineAPI", n);

With this, the console auto-complete fails silently while statements typed in console will fail to execute (the exception will be logged).

• Object.defineProperty
• Object.getOwnPropertyDescriptor
• Chrome's console.log function (for tips on formatting output)

 Step 1:

    Locate phpMyAdmin installation path.

    Step 2:

    Open phpMyAdmin>config.inc.php in your favourite text editor.

    Step 3:

    $cfg['Servers'][$i]['auth_type'] = 'config';
    $cfg['Servers'][$i]['user'] = 'root';
    $cfg['Servers'][$i]['password'] = '';
    $cfg['Servers'][$i]['extension'] = 'mysqli';
    $cfg['Servers'][$i]['AllowNoPassword'] = true;
    $cfg['Lang'] = '';

You need to include the path of the libraries inside /etc/ld.so.conf, and rerun ldconfig to upate the list

Other possibility is to include in the env variable LD_LIBRARY_PATH the path to your library, and rerun the executable.

check the symbolic links if they point to a valid library ...

You can add the path directly in /etc/ld.so.conf, without include...

run ldconfig -p to see whether your library is well included in the cache.

If you are adding integers, as you say in your question, this will add 50 (from 1 to 50):

for (int x = 1; x <= 50; x++)
{
   list.Items.Add(x);
}

You do not need to set DisplayMember and ValueMember unless you are adding objects that have specific properties that you want to display to the user. In your example:

listbox1.Items.Add(new { clan = "Foo", sifOsoba = 1234 });

The version of the Apache HTTP client provided on stock Android was very very old.

Google Android 1.0 was released with a pre-BETA snapshot of Apache HttpClient. To coincide with the first Android release Apache HttpClient 4.0 APIs had to be frozen prematurely, while many of interfaces and internal structures were still not fully worked out. As Apache HttpClient 4.0 was maturing the project was expecting Google to incorporate the latest code improvements into their code tree. Unfortunately it did not happen.

While you could keep using the old deprecated library via the useLibrary 'org.apache.http.legacy' workaround (suggested by @Jinu and others), you really need to bite the bullet and update to something else, for example the native Android HttpUrlConnection, or if that doesn't meet your needs, you can use the OkHttp library, which is what HttpUrlConnection is internally based upon anyway.

OkHttp actually has a compatibility layer that uses the same API as the Apache client, though they don't implement all of the same features, so your mileage may vary.

While it is possible to import a newer version of the Apache client (as suggested by @MartinPfeffer), it's likely that most of the classes and methods you were using before have been deprecated, and there is a pretty big risk that updating will introduce bugs in your code (for example I found some connections that previously worked from behind a proxy no longer worked), so this isn't a great solution.

REST is a software design pattern typically used for web applications. In layman's terms this means that it is a commonly used idea used in many different projects. It stands for REpresentational State Transfer. The basic idea of REST is treating objects on the server-side (as in rows in a database table) as resources than can be created or destroyed.

The most basic way of thinking about REST is as a way of formatting the URLs of your web applications. For example, if your resource was called "posts", then:

/posts Would be how a user would access ALL the posts, for displaying.

/posts/:id Would be how a user would access and view an individual post, retrieved based on their unique id.

/posts/new Would be how you would display a form for creating a new post.

Sending a POST request to /users would be how you would actually create a new post on the database level.

Sending a PUT request to /users/:id would be how you would update the attributes of a given post, again identified by a unique id.

Sending a DELETE request to /users/:id would be how you would delete a given post, again identified by a unique id.

As I understand it, the REST pattern was mainly popularized (for web apps) by the Ruby on Rails framework, which puts a big emphasis on RESTful routes. I could be wrong about that though.

I may not be the most qualified to talk about it, but this is how I've learned it (specifically for Rails development).

When someone refers to a "REST api," generally what they mean is an api that uses RESTful urls for retrieving data.

you can write in your console:

git pull origin

then press TAB and write your "master" repository

I know of few packages that support "make uninstall" but many more that support make install DESTDIR=xxx" for staged installs.

You can use this to create a package which you install instead of installing directly from the source. I had no luck with checkinstall but fpm works very well.

This can also help you remove a package previously installed using make install. You simply force install your built package over the make installed one and then uninstall it.

For example, I used this recently to deal with protobuf-3.3.0. On RHEL7:

make install DESTDIR=dest
cd dest
fpm -f -s dir -t rpm -n protobuf -v 3.3.0 \
 --vendor "You Not RedHat" \
 --license "Google?" \
 --description "protocol buffers" \
 --rpm-dist el7 \
 -m [email protected] \
 --url "http:/somewhere/where/you/get/the/package/oritssource" \
 --rpm-autoreqprov \
 usr

 sudo rpm -i -f protobuf-3.3.0-1.el7.x86_64.rpm
 sudo rpm -e protobuf-3.3.0      

Prefer yum to rpm if you can.

On Debian9:

make install DESTDIR=dest
cd dest
fpm -f -s dir -t deb -n protobuf -v 3.3.0 \
-C `pwd` \
--prefix / \
--vendor "You Not Debian" \
--license "$(grep Copyright ../../LICENSE)" \
--description "$(cat README.adoc)" \
--deb-upstream-changelog ../../CHANGES.txt \
 --url "http:/somewhere/where/you/get/the/package/oritssource" \
 usr/local/bin \
 usr/local/lib \
 usr/local/include

 sudo apt install -f *.deb
 sudo apt-get remove protobuf

Prefer apt to dpkg where you can.

I used read_csv from the readr package

In my experience, the parameter row.names=NULL in the read.csv function will lead to a wrong reading of the file if a column name is missing, i.e. every column will be shifted.

read_csv solves this.

See,

There are two ways to convert an RDD to DF in Spark.

toDF() and createDataFrame(rdd, schema)

I will show you how you can do that dynamically.

toDF()

The toDF() command gives you the way to convert an RDD[Row] to a Dataframe. The point is, the object Row() can receive a **kwargs argument. So, there is an easy way to do that.

from pyspark.sql.types import Row

#here you are going to create a function
def f(x):
    d = {}
    for i in range(len(x)):
        d[str(i)] = x[i]
    return d

#Now populate that
df = rdd.map(lambda x: Row(**f(x))).toDF()

This way you are going to be able to create a dataframe dynamically.

createDataFrame(rdd, schema)

Other way to do that is creating a dynamic schema. How?

This way:

from pyspark.sql.types import StructType
from pyspark.sql.types import StructField
from pyspark.sql.types import StringType

schema = StructType([StructField(str(i), StringType(), True) for i in range(32)])

df = sqlContext.createDataFrame(rdd, schema)

This second way is cleaner to do that...

So this is how you can create dataframes dynamically.

Open your Ruby on Rails console and enter:

ActiveRecord::Migration.rename_column :tablename, :old_column, :new_column

what you have is fine - however to save some typing, you can simply use for your data

data: $('#formId').serialize()

see http://www.ryancoughlin.com/2009/05/04/how-to-use-jquery-to-serialize-ajax-forms/ for details, the syntax is pretty basic.

With default Github repository import it is possible, but just make sure the two factor authentication is not enabled in Gitlab.

public void postData(String url,JSONObject obj) {
    // Create a new HttpClient and Post Header

    HttpParams myParams = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(myParams, 10000);
    HttpConnectionParams.setSoTimeout(myParams, 10000);
    HttpClient httpclient = new DefaultHttpClient(myParams );

    try {

        HttpPost httppost = new HttpPost(url.toString());
        httppost.setHeader("Content-type", "application/json");

        StringEntity se = new StringEntity(obj.toString()); 
        se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
        httppost.setEntity(se);

reload() is supposed to accept an argument which tells it to do a hard reload, ie, ignoring the cache:

location.reload(true);

I can't vouch for its reliability, you may want to investigate this further.

If you compute modulo a power of two, using bitwise AND is simpler and generally faster than performing division. If b is a power of two, a % b == a & (b - 1).

For example, let's take a value in register EAX, modulo 64.
The simplest way would be AND EAX, 63, because 63 is 111111 in binary.

The masked, higher digits are not of interest to us. Try it out!

Analogically, instead of using MUL or DIV with powers of two, bit-shifting is the way to go. Beware signed integers, though!

I use a little bit modified version of a method described here: https://stackoverflow.com/a/5311362/563175

So it looks like that:

kill `pstree -p 24901 | sed 's/(/\n(/g' | grep '(' | sed 's/(\(.*\)).*/\1/' | tr "\n" " "`

where 24901 is parent's PID.

It looks pretty ugly but does it's job perfectly.

You can use the function file_get_contents();

if(file_get_contents('https://example.com/example.txt')) {
    //File exists
}

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .

If lakes is your DataFrame, you can do something like

area_dict = dict(zip(lakes.area, lakes.count))

You can use this simple plugin as $('#some_id').getAttributes();

(function($) {
    $.fn.getAttributes = function() {
        var attributes = {}; 

        if( this.length ) {
            $.each( this[0].attributes, function( index, attr ) {
                attributes[ attr.name ] = attr.value;
            } ); 
        }

        return attributes;
    };
})(jQuery);

Dirk's method above will absolutely work, but if you're looking for a way to bring in a long string where whitespace/structure is important to preserve (example: a SQL query using RODBC) there is a two step solution.

1) Bring the text string in across multiple lines

long_string <- "this
is 
a 
long
string
with
whitespace"

2) R will introduce a bunch of \n characters. Strip those out with strwrap(), which destroys whitespace, per the documentation:

strwrap(long_string, width=10000, simplify=TRUE)

By telling strwrap to wrap your text to a very, very long row, you get a single character vector with no whitespace/newline characters.

With Java 8 there is this API method to accomplish your requirement.

map.putIfAbsent(key, value)

If the specified key is not already associated with a value (or is mapped to null) associates it with the given value and returns null, else returns the current value.

For a>b:

def gcd(a, b):

    if(a<b):
        a,b=b,a
        
    while(b!=0):
        r,b=b,a%r
        a=r
    return a

For either a>b or a<b:

def gcd(a, b):

    t = min(a, b)

    # Keep looping until t divides both a & b evenly
    while a % t != 0 or b % t != 0:
        t -= 1

    return t

I'm on Windows and I couldn't get any of this stuff to work. I kept getting errors about files being in the way. This worked though:

cd %APPDATA%\nvm\v8.10.0           # or whatever version you're using
mv npm npm-old
mv npm.cmd npm-old.cmd
cd node_modules\
mv npm npm-old
cd npm-old\bin
node npm-cli.js i -g npm@latest

cd %APPDATA%\nvm\v8.10.0 # or whatever version you're using
rm npm-old
rm npm-old.cmd
cd node_modules\
rm -rf npm-old

And boom, I'm back in business.

It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.

In your case the variable can be declared like this:

<variable name="total" class="java.lang.Integer" calculation="Sum">
    <variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>

• the Calculation type is Sum;
• the Reset type is Report;
• the Variable expression is $F{payment}, where $F{payment} is the name of a field contains sum (Doctor Payment).

The working example.

GNU awk 4.1

awk -niord '$0=chr("0x"RT)' RS=.. ORS=

Note that if you echo to this it will produce an extra null byte

$ echo 595a | awk -niord '$0=chr("0x"RT)' RS=.. ORS= | od -tx1c
0000000  59  5a  00
          Y   Z  \0

Instead use printf

$ printf 595a | awk -niord '$0=chr("0x"RT)' RS=.. ORS= | od -tx1c
0000000  59  5a
          Y   Z

Also note that GNU awk produces UTF-8 by default

$ printf a1 | awk -niord '$0=chr("0x"RT)' RS=.. ORS= | od -tx1
0000000 c2 a1

If you are dealing with characters outside of ASCII, and you are going to be Base64 encoding the resultant string, you can disable UTF-8 with -b

echo 5a | sha256sum | awk -bniord 'RT~/\w/,$0=chr("0x"RT)' RS=.. ORS=

I was having problems here (i.e. sending form-data whilst uploading a file) until I used the following:

files = {'file': (filename, open(filepath, 'rb'), 'text/xml'),
         'Content-Disposition': 'form-data; name="file"; filename="' + filename + '"',
         'Content-Type': 'text/xml'}

That's the input that ended up working for me. In Chrome Dev Tools -> Network tab, I clicked the request I was interested in. In the Headers tab, there's a Form Data section, and it showed both the Content-Disposition and the Content-Type headers being set there.

I did NOT need to set headers in the actual requests.post() command for this to succeed (including them actually caused it to fail)

Thanks to dimo414's answer, this shows how his great solution works, and shows that you can have quotes and variables in the text easily as well:

example output

$ ./test.sh

The text from the example function is:
  Welcome dev: Would you "like" to know how many 'files' there are in /tmp?

  There are "      38" files in /tmp, according to the "wc" command

test.sh

#!/bin/bash

function text1()
{
  COUNT=$(\ls /tmp | wc -l)
cat <<EOF

  $1 Would you "like" to know how many 'files' there are in /tmp?

  There are "$COUNT" files in /tmp, according to the "wc" command

EOF
}

function main()
{
  OUT=$(text1 "Welcome dev:")
  echo "The text from the example function is: $OUT"
}

main

str = "M" + str.Substring(1);

If you'll do several such changes use a StringBuilder or a char[].

(The threshold of when StringBuilder becomes quicker is after about 5 concatenations or substrings, but note that grouped concatenations of a + "b" + c + d + "e" + f are done in a single call and compile-type concatenations of "a" + "b" + "c" don't require a call at all).

It may seem that having to do this is horribly inefficient, but the fact that strings can't be changes allows for lots of efficiency gains and other advantages such as mentioned at Why .NET String is immutable?

Hi all Please try this property

$( "p span" ).last().addClass( "highlight" );

From Python 3.3 on, there is the official Python launcher for Windows (http://www.python.org/dev/peps/pep-0397/). Now, you can use the #!pythonX to determine the wanted version of the interpreter also on Windows. See more details in my another comment or read the PEP 397.

Summary: The py script.py launches the Python version stated in #! or Python 2 if #! is missing. The py -3 script.py launches the Python 3.

I think one way is first to check whether your file exists and if it exists to exclude the folder from copy:

<target name="excludeLocales">

    <property name="de-DE.file" value="${basedir}/locale/de-DE/incompelte.flag"/>
    <available property="de-DE.file.exists" file="${de-DE.file}" />

    <copy todir="C:/temp/">
        <fileset dir="${basedir}/locale">
            <exclude name="de-DE/**" if="${de-DE.file.exists}"/>
            <include name="xy/**"/>
        </fileset>
    </copy>
</target>

This should work also for the other languages.

I am sure there is ANT tags to do it but have used this 7zip hack in .bat script. I use http://www.7-zip.org/ command line tool. All the times I use this for changing jdbc url within j2ee context.xml file.

mkdir .\temp-install
c:\apps\commands\7za.exe x -y mywebapp.war META-INF/context.xml -otemp-install\mywebapp
..here I have small tool to replace text in xml file..
c:\apps\commands\7za.exe u -y -tzip mywebapp.war ./temp-install/mywebapp/*
rmdir /Q /S .\temp-install

You could extract entire .war file (its zip after all), delete files, replace files, add files, modify files and repackage to .war archive file. But changing one file in a large .war archive this might be best extracting specific file and then update original archive.

Assuming you are trying to find if a div exists

$('div').length ? alert('div found') : alert('Div not found')

Check working example at http://jsfiddle.net/Qr86J/1/

$('body').removeClass('modal-open'); // For scroll run
$('#modal').modal('hide');

    ) ) as pivottable;

SP is the stack register a shortcut for typing r13. LR is the link register a shortcut for r14. And PC is the program counter a shortcut for typing r15.

When you perform a call, called a branch link instruction, bl, the return address is placed in r14, the link register. the program counter pc is changed to the address you are branching to.

There are a few stack pointers in the traditional ARM cores (the cortex-m series being an exception) when you hit an interrupt for example you are using a different stack than when running in the foreground, you dont have to change your code just use sp or r13 as normal the hardware has done the switch for you and uses the correct one when it decodes the instructions.

The traditional ARM instruction set (not thumb) gives you the freedom to use the stack in a grows up from lower addresses to higher addresses or grows down from high address to low addresses. the compilers and most folks set the stack pointer high and have it grow down from high addresses to lower addresses. For example maybe you have ram from 0x20000000 to 0x20008000 you set your linker script to build your program to run/use 0x20000000 and set your stack pointer to 0x20008000 in your startup code, at least the system/user stack pointer, you have to divide up the memory for other stacks if you need/use them.

Stack is just memory. Processors normally have special memory read/write instructions that are PC based and some that are stack based. The stack ones at a minimum are usually named push and pop but dont have to be (as with the traditional arm instructions).

If you go to http://github.com/lsasim I created a teaching processor and have an assembly language tutorial. Somewhere in there I go through a discussion about stacks. It is NOT an arm processor but the story is the same it should translate directly to what you are trying to understand on the arm or most other processors.

Say for example you have 20 variables you need in your program but only 16 registers minus at least three of them (sp, lr, pc) that are special purpose. You are going to have to keep some of your variables in ram. Lets say that r5 holds a variable that you use often enough that you dont want to keep it in ram, but there is one section of code where you really need another register to do something and r5 is not being used, you can save r5 on the stack with minimal effort while you reuse r5 for something else, then later, easily, restore it.

Traditional (well not all the way back to the beginning) arm syntax:

...
stmdb r13!,{r5}
...temporarily use r5 for something else...
ldmia r13!,{r5}
...

stm is store multiple you can save more than one register at a time, up to all of them in one instruction.

db means decrement before, this is a downward moving stack from high addresses to lower addresses.

You can use r13 or sp here to indicate the stack pointer. This particular instruction is not limited to stack operations, can be used for other things.

The ! means update the r13 register with the new address after it completes, here again stm can be used for non-stack operations so you might not want to change the base address register, leave the ! off in that case.

Then in the brackets { } list the registers you want to save, comma separated.

ldmia is the reverse, ldm means load multiple. ia means increment after and the rest is the same as stm

So if your stack pointer were at 0x20008000 when you hit the stmdb instruction seeing as there is one 32 bit register in the list it will decrement before it uses it the value in r13 so 0x20007FFC then it writes r5 to 0x20007FFC in memory and saves the value 0x20007FFC in r13. Later, assuming you have no bugs when you get to the ldmia instruction r13 has 0x20007FFC in it there is a single register in the list r5. So it reads memory at 0x20007FFC puts that value in r5, ia means increment after so 0x20007FFC increments one register size to 0x20008000 and the ! means write that number to r13 to complete the instruction.

Why would you use the stack instead of just a fixed memory location? Well the beauty of the above is that r13 can be anywhere it could be 0x20007654 when you run that code or 0x20002000 or whatever and the code still functions, even better if you use that code in a loop or with recursion it works and for each level of recursion you go you save a new copy of r5, you might have 30 saved copies depending on where you are in that loop. and as it unrolls it puts all the copies back as desired. with a single fixed memory location that doesnt work. This translates directly to C code as an example:

void myfun ( void )
{
   int somedata;
}

In a C program like that the variable somedata lives on the stack, if you called myfun recursively you would have multiple copies of the value for somedata depending on how deep in the recursion. Also since that variable is only used within the function and is not needed elsewhere then you perhaps dont want to burn an amount of system memory for that variable for the life of the program you only want those bytes when in that function and free that memory when not in that function. that is what a stack is used for.

A global variable would not be found on the stack.

Going back...

Say you wanted to implement and call that function you would have some code/function you are in when you call the myfun function. The myfun function wants to use r5 and r6 when it is operating on something but it doesnt want to trash whatever someone called it was using r5 and r6 for so for the duration of myfun() you would want to save those registers on the stack. Likewise if you look into the branch link instruction (bl) and the link register lr (r14) there is only one link register, if you call a function from a function you will need to save the link register on each call otherwise you cant return.

...
bl myfun
    <--- the return from my fun returns here
...


myfun:
stmdb sp!,{r5,r6,lr}
sub sp,#4 <--- make room for the somedata variable
...
some code here that uses r5 and r6
bl more_fun <-- this modifies lr, if we didnt save lr we wouldnt be able to return from myfun
   <---- more_fun() returns here
...
add sp,#4 <-- take back the stack memory we allocated for the somedata variable
ldmia sp!,{r5,r6,lr}
mov pc,lr <---- return to whomever called myfun.

So hopefully you can see both the stack usage and link register. Other processors do the same kinds of things in a different way. for example some will put the return value on the stack and when you execute the return function it knows where to return to by pulling a value off of the stack. Compilers C/C++, etc will normally have a "calling convention" or application interface (ABI and EABI are names for the ones ARM has defined). if every function follows the calling convention, puts parameters it is passing to functions being called in the right registers or on the stack per the convention. And each function follows the rules as to what registers it does not have to preserve the contents of and what registers it has to preserve the contents of then you can have functions call functions call functions and do recursion and all kinds of things, so long as the stack does not go so deep that it runs into the memory used for globals and the heap and such, you can call functions and return from them all day long. The above implementation of myfun is very similar to what you would see a compiler produce.

ARM has many cores now and a few instruction sets the cortex-m series works a little differently as far as not having a bunch of modes and different stack pointers. And when executing thumb instructions in thumb mode you use the push and pop instructions which do not give you the freedom to use any register like stm it only uses r13 (sp) and you cannot save all the registers only a specific subset of them. the popular arm assemblers allow you to use

push {r5,r6}
...
pop {r5,r6}

in arm code as well as thumb code. For the arm code it encodes the proper stmdb and ldmia. (in thumb mode you also dont have the choice as to when and where you use db, decrement before, and ia, increment after).

No you absolutly do not have to use the same registers and you dont have to pair up the same number of registers.

push {r5,r6,r7}
...
pop {r2,r3}
...
pop {r1}

assuming there is no other stack pointer modifications in between those instructions if you remember the sp is going to be decremented 12 bytes for the push lets say from 0x1000 to 0x0FF4, r5 will be written to 0xFF4, r6 to 0xFF8 and r7 to 0xFFC the stack pointer will change to 0x0FF4. the first pop will take the value at 0x0FF4 and put that in r2 then the value at 0x0FF8 and put that in r3 the stack pointer gets the value 0x0FFC. later the last pop, the sp is 0x0FFC that is read and the value placed in r1, the stack pointer then gets the value 0x1000, where it started.

The ARM ARM, ARM Architectural Reference Manual (infocenter.arm.com, reference manuals, find the one for ARMv5 and download it, this is the traditional ARM ARM with ARM and thumb instructions) contains pseudo code for the ldm and stm ARM istructions for the complete picture as to how these are used. Likewise well the whole book is about the arm and how to program it. Up front the programmers model chapter walks you through all of the registers in all of the modes, etc.

If you are programming an ARM processor you should start by determining (the chip vendor should tell you, ARM does not make chips it makes cores that chip vendors put in their chips) exactly which core you have. Then go to the arm website and find the ARM ARM for that family and find the TRM (technical reference manual) for the specific core including revision if the vendor has supplied that (r2p0 means revision 2.0 (two point zero, 2p0)), even if there is a newer rev, use the manual that goes with the one the vendor used in their design. Not every core supports every instruction or mode the TRM tells you the modes and instructions supported the ARM ARM throws a blanket over the features for the whole family of processors that that core lives in. Note that the ARM7TDMI is an ARMv4 NOT an ARMv7 likewise the ARM9 is not an ARMv9. ARMvNUMBER is the family name ARM7, ARM11 without a v is the core name. The newer cores have names like Cortex and mpcore instead of the ARMNUMBER thing, which reduces confusion. Of course they had to add the confusion back by making an ARMv7-m (cortex-MNUMBER) and the ARMv7-a (Cortex-ANUMBER) which are very different families, one is for heavy loads, desktops, laptops, etc the other is for microcontrollers, clocks and blinking lights on a coffee maker and things like that. google beagleboard (Cortex-A) and the stm32 value line discovery board (Cortex-M) to get a feel for the differences. Or even the open-rd.org board which uses multiple cores at more than a gigahertz or the newer tegra 2 from nvidia, same deal super scaler, muti core, multi gigahertz. A cortex-m barely brakes the 100MHz barrier and has memory measured in kbytes although it probably runs of a battery for months if you wanted it to where a cortex-a not so much.

sorry for the very long post, hope it is useful.

Based on Documentation

Amending the message of older or multiple commit messages

git rebase -i HEAD~3 

The above displays a list of the last 3 commits on the current branch, change 3 to something else if you want more. The list will look similar to the following:

pick e499d89 Delete CNAME
pick 0c39034 Better README
pick f7fde4a Change the commit message but push the same commit.

Replace pick with reword before each commit message you want to change. Let say you change the second commit in the list, your file will look like the following:

pick e499d89 Delete CNAME
reword 0c39034 Better README
pick f7fde4a Change the commit message but push the same commit.

Save and close the commit list file, this will pop up a new editer for you to change your commit message, change the commit message and save.

Finaly Force-push the amended commits.

git push --force

I had that issue : use path module

const path = require('path');

and also do not forget to create the uploads directory first period.

Another option is to archive the operational data on a [daily|hourly|whatever] basis. Most database engines support the extraction of the data into an archive.

Basically, the idea is to create a scheduled Windows or CRON job that

1. determines the current tables in the operational database
2. selects all data from every table into a CSV or XML file
3. compresses the exported data to a ZIP file, preferably with the timestamp of the generation in the file name for easier archiving.

Many SQL database engines come with a tool that can be used for this purpose. For example, when using MySQL on Linux, the following command can be used in a CRON job to schedule the extraction:

mysqldump --all-databases --xml --lock-tables=false -ppassword | gzip -c | cat > /media/bak/servername-$(date +%Y-%m-%d)-mysql.xml.gz

I think you can use thread like demon-thread for reading your input and your output reader will already be in while loop in main thread so you can read and write at same time.You can modify your program like this:

Thread T=new Thread(new Runnable() {

    @Override
    public void run() {
        while(true)
        {
            String input = scan.nextLine();
            input += "\n";
            try {
                writer.write(input);
                writer.flush();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }

    }
} );
T.start();

and you can reader will be same as above i.e.

while ((line = reader.readLine ()) != null) {
    System.out.println ("Stdout: " + line);
}

make your writer as final otherwise it wont be able to accessible by inner class.

Be very, very aware of this problem that can occur when using utf8_general_ci.

MySQL will not distinguish between some characters in select statements, if the utf8_general_ci collation is used. This can lead to very nasty bugs - especially for example, where usernames are involved. Depending on the implementation that uses the database tables, this problem could allow malicious users to create a username matching an administrator account.

This problem exposes itself at the very least in early 5.x versions - I'm not sure if this behaviour as changed later.

I'm no DBA, but to avoid this problem, I always go with utf8-bin instead of a case-insensitive one.

The script below describes the problem by example.

-- first, create a sandbox to play in
CREATE DATABASE `sandbox`;
use `sandbox`;

-- next, make sure that your client connection is of the same 
-- character/collate type as the one we're going to test next:
charset utf8 collate utf8_general_ci

-- now, create the table and fill it with values
CREATE TABLE `test` (`key` VARCHAR(16), `value` VARCHAR(16) )
    CHARACTER SET utf8 COLLATE utf8_general_ci;

INSERT INTO `test` VALUES ('Key ONE', 'value'), ('Key TWO', 'valúe');

-- (verify)
SELECT * FROM `test`;

-- now, expose the problem/bug:
SELECT * FROM test WHERE `value` = 'value';

--
-- Note that we get BOTH keys here! MySQLs UTF8 collates that are 
-- case insensitive (ending with _ci) do not distinguish between 
-- both values!
--
-- collate 'utf8_bin' doesn't have this problem, as I'll show next:
--

-- first, reset the client connection charset/collate type
charset utf8 collate utf8_bin

-- next, convert the values that we've previously inserted in the table
ALTER TABLE `test` CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;

-- now, re-check for the bug
SELECT * FROM test WHERE `value` = 'value';

--
-- Note that we get just one key now, as you'd expect.
--
-- This problem appears to be specific to utf8. Next, I'll try to 
-- do the same with the 'latin1' charset:
--

-- first, reset the client connection charset/collate type
charset latin1 collate latin1_general_ci

-- next, convert the values that we've previously inserted
-- in the table
ALTER TABLE `test` CONVERT TO CHARACTER SET latin1 COLLATE latin1_general_ci;

-- now, re-check for the bug
SELECT * FROM test WHERE `value` = 'value';

--
-- Again, only one key is returned (expected). This shows 
-- that the problem with utf8/utf8_generic_ci isn't present 
-- in latin1/latin1_general_ci
--
-- To complete the example, I'll check with the binary collate
-- of latin1 as well:

-- first, reset the client connection charset/collate type
charset latin1 collate latin1_bin

-- next, convert the values that we've previously inserted in the table
ALTER TABLE `test` CONVERT TO CHARACTER SET latin1 COLLATE latin1_bin;

-- now, re-check for the bug
SELECT * FROM test WHERE `value` = 'value';

--
-- Again, only one key is returned (expected).
--
-- Finally, I'll re-introduce the problem in the exact same 
-- way (for any sceptics out there):

-- first, reset the client connection charset/collate type
charset utf8 collate utf8_generic_ci

-- next, convert the values that we've previously inserted in the table
ALTER TABLE `test` CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

-- now, re-check for the problem/bug
SELECT * FROM test WHERE `value` = 'value';

--
-- Two keys.

DROP DATABASE sandbox;

Try this:

div {
    border: 1px solid black;
    width: 70px;
    overflow: hidden;
    white-space: nowrap;
}

You don't need to convert your dates to timestamp before the sorting, but it's a good idea though because it will take more time to sort without it.

$data = array(
    array(
        "title" => "Another title",
        "date"  => "Fri, 17 Jun 2011 08:55:57 +0200"
    ),
    array(
        "title" => "My title",
        "date"  => "Mon, 16 Jun 2010 06:55:57 +0200"
    )
);

function sortFunction( $a, $b ) {
    return strtotime($a["date"]) - strtotime($b["date"]);
}
usort($data, "sortFunction");
var_dump($data);

Look at git stash to put all of your local changes into a "stash file" and revert to the last commit. At that point, you can apply your stashed changes, or discard them.

You can use w.setMenu(null) or set frame: false (this also removes buttons for close, minimize and maximize options) on your window. See setMenu() or BrowserWindow(). Also check this thread

Electron now has win.removeMenu() (added in v5.0.0), to remove application menus instead of using win.setMenu(null).

Electron 7.1.x seems to have a bug where win.removeMenu() doesn't work. The only workaround is to use Menu.setApplicationMenu(null)

You can write your own WriteLine method-

public static void WriteLine<T>(T obj)
    {
        var t = typeof(T);
        var props = t.GetProperties();
        StringBuilder sb = new StringBuilder();
        foreach (var item in props)
        {
            sb.Append($"{item.Name}:{item.GetValue(obj,null)}; ");
        }
        sb.AppendLine();
        Console.WriteLine(sb.ToString());
    }

Use it like-

WriteLine(myObject);

To write a collection we can use-

 var ifaces = t.GetInterfaces();
        if (ifaces.Any(o => o.Name.StartsWith("ICollection")))
        {

            dynamic lst = t.GetMethod("GetEnumerator").Invoke(obj, null);
            while (lst.MoveNext())
            {
                WriteLine(lst.Current);
            }
        }   

The method may look like-

 public static void WriteLine<T>(T obj)
    {
        var t = typeof(T);
        var ifaces = t.GetInterfaces();
        if (ifaces.Any(o => o.Name.StartsWith("ICollection")))
        {

            dynamic lst = t.GetMethod("GetEnumerator").Invoke(obj, null);
            while (lst.MoveNext())
            {
                WriteLine(lst.Current);
            }
        }            
        else if (t.GetProperties().Any())
        {
            var props = t.GetProperties();
            StringBuilder sb = new StringBuilder();
            foreach (var item in props)
            {
                sb.Append($"{item.Name}:{item.GetValue(obj, null)}; ");
            }
            sb.AppendLine();
            Console.WriteLine(sb.ToString());
        }
    }

Using if, else if and checking interfaces, attributes, base type, etc. and recursion (as this is a recursive method) in this way we may achieve an object dumper, but it is tedious for sure. Using the object dumper from Microsoft's LINQ Sample would save your time.

Rene, your HOME variable isn't set correctly. Either change it to c:\Users\(your-username) or just to %USERNAME%.

When using Windows.Web.Http namespace, for POST instead of FormUrlEncodedContent we write HttpFormUrlEncodedContent. Also the response is type of HttpResponseMessage. The rest is as Evan Mulawski wrote down.

I've found that some of the suggested answers which drill down into the MemberExpression/UnaryExpression don't capture nested/subproperties.

ex) o => o.Thing1.Thing2 returns Thing1 rather than Thing1.Thing2.

This distinction is important if you're trying to work with EntityFramework DbSet.Include(...).

I've found that just parsing the Expression.ToString() seems to work fine, and comparatively quickly. I compared it against the UnaryExpression version, and even getting ToString off of the Member/UnaryExpression to see if that was faster, but the difference was negligible. Please correct me if this is a terrible idea.

To change working directory in GitMSYS's Git Bash you can just use cd

cd /path/do/directory

Note that:

• Directory separators use the forward-slash (/) instead of backslash.
• Drives are specified with a lower case letter and no colon, e.g. "C:\stuff" should be represented with "/c/stuff".
• Spaces can be escaped with a backslash (\)
• Command line completion is your friend. Press TAB at anytime to expand stuff, including Git options, branches, tags, and directories.

Also, you can right click in Windows Explorer on a directory and "Git Bash here".

You should remove the '@' before 'name'; it's not needed anymore (for current jQuery versions).

You're want to return all checked elements with name 'test2', but you don't have any elements with that name, you're using an id of 'test2'.

If you're going to use IDs, just try:

return $('#test2').attr('checked');

Getting a product key is free. Here is how I did it:

I just downloaded the 2012 Express install ISO image. After install I got the message "This product will expire in 30 day(s). Registration is required for the continued use of Microsoft Visual Studio Express 2012 for Web."

On that same screen is a register online link. Clicking that I signed in with my live account, updated my profile, and got a registration key.

The first line moves the cursor to the last non-empty row in the column. The second line prints that columns row.

Selection.End(xlDown).Select
MsgBox(ActiveCell.Row)

I faced this issue recently and surprisingly only i was having this problem and none of my team members were facing this issue when building the project code.

On debugging i found that my code directory had spacing issue , It was D:\GIT Workspace\abc\xyz.

As a quick fix i changed it to D:\GITWS\abc\xyz and it solved the problem.

I agree with Mike, though I'm a Vim die-hard. I've been using GEdit quite frequently lately when I'm doing lightweight Ruby scripting. The standard editor (plus Ruby code snippets) is extremely usable and polished, and can provide a nice reprieve from full-strength, always-on programming editors.

pythonz, an active fork of pythonbrew, makes this a breeze. You can install a version with:

# pythonz install 2.7.3

Then set up a symlink with:

# ln -s /usr/local/pythonz/pythons/CPython-2.7.3/bin/python2.7 /usr/local/bin/python2.7
# python2.7 --version
Python 2.7.3

Here's how I'd do it...

writeToParcel:

dest.writeByte((byte) (myBoolean ? 1 : 0));     //if myBoolean == true, byte == 1

readFromParcel:

myBoolean = in.readByte() != 0;     //myBoolean == true if byte != 0

Did you try to chomp the $str1 and $str2?

I found a similar issue with using (another) $str1 eq 'Y' and it only went away when I first did:

chomp($str1);
if ($str1 eq 'Y') {
....
}

works after that.

Hope that helps.

Try 'build-essential' instead.

Angular no longer supports --env instead you have to use

ng serve -c dev

for development environment and,

ng serve -c prod 

for production.

NOTE: -c or --configuration

The fastest way to copy a database is to detach-copy-attach method, but the production users will not have database access while the prod db is detached. You can do something like this if your production DB is for example a Point of Sale system that nobody uses during the night.

If you cannot detach the production db you should use backup and restore.

You will have to create the logins if they are not in the new instance. I do not recommend you to copy the system databases.

You can use the SQL Server Management Studio to create the scripts that create the logins you need. Right click on the login you need to create and select Script Login As / Create.

This will lists the orphaned users:

EXEC sp_change_users_login 'Report'

If you already have a login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'Auto_Fix', 'user'

If you want to create a new login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'Auto_Fix', 'user', 'login', 'password'

SQLDeveloper can do this.

http://sqldeveloper.solyp.com/

It also can happen when you try to UPDATE a PRIMARY KEY.

For those also using typescript on node-js and are getting a ReferenceError: fetch is not defined error

npm install these packages:

    "amazon-cognito-identity-js": "3.0.11"
    "node-fetch": "^2.3.0"

Then include:

import Global = NodeJS.Global;
export interface GlobalWithCognitoFix extends Global {
    fetch: any
}
declare const global: GlobalWithCognitoFix;
global.fetch = require('node-fetch');

You can't import from the parent directory without some voodoo. Here's yet another way that works with at least Python 3.6.

First, have a file test/context.py with the following content:

import sys
import os
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))

Then have the following import in the file test/test_antigravity.py:

import unittest
try:
    import context
except ModuleNotFoundError:
    import test.context    
import antigravity

Note that the reason for this try-except clause is that

• import test.context fails when run with "python test_antigravity.py" and
• import context fails when run with "python -m unittest" from the new_project directory.

With this trickery they both work.

Now you can run all the test files within test directory with:

$ pwd
/projects/new_project
$ python -m unittest

or run an individual test file with:

$ cd test
$ python test_antigravity

Ok, it's not much prettier than having the content of context.py within test_antigravity.py, but maybe a little. Suggestions are welcome.

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

Round has an optional parameter

Select round(123.456, 2, 1)  will = 123.45
Select round(123.456, 2, 0)  will = 123.46

Here I propose a way to do this exclusively using the Bootstrap framework built-in functionality.

1. You need to make sure the target div has an ID.
2. Bootstrap has a class "collapse", this will hide your block by default. If you want your div to be collapsible AND be shown by default you need to add "in" class to the collapse. Otherwise the toggle behavior will not work properly.
3. Then, on your hyperlink (also works for buttons), add an href attribute that points to your target div.
4. Finally, add the attribute data-toggle="collapse" to instruct Bootstrap to add an appropriate toggle script to this tag.

Here is a code sample than can be copy-pasted directly on a page that already includes Bootstrap framework (up to version 3.4.1):

<a href="#Foo" class="btn btn-default" data-toggle="collapse">Toggle Foo</a>
<button href="#Bar" class="btn btn-default" data-toggle="collapse">Toggle Bar</button>
<div id="Foo" class="collapse">
    This div (Foo) is hidden by default
</div>
<div id="Bar" class="collapse in">
    This div (Bar) is shown by default and can toggle
</div>

There are possible steps to enable auto increment for a column. I guess the phpMyAdmin version is 3.5.5 but not sure.

Click on Table > Structure tab > Under Action Click Primary (set as primary), click on Change on the pop-up window, scroll left and check A_I. Also make sure you have selected None for Default

You can literally convert it into float using:

float_value = float(integer_value)

Likewise, you can convert an integer back to float datatype with:

integer_value = int(float_value)

Hope it helped. I advice you to read "Build-In Functions of Python" at this link: https://docs.python.org/2/library/functions.html

go to sdk folder, then go to tools.
copy your apk file inside the tool directory
./emulator -avd myEmulator
to run the emulator on mac 
./adb install myApp.apk
to install app on the emulator

You can simply use:

ps -o args= -f -p ProcessPid

An integer value is a mathematical representation of a number and is ignorant of leading zeroes.

You can get a string with leading zeroes like this:

someNumber.ToString("00000000")

CSS has a text-align: center property, and since this is purely a visual thing, not semantic, it should be relegated to CSS, not HTML.

As a result:

Above styles work outside codeblocks, otherwise:

REM is another way to comment.

There's another very simple answer which can work for some simple graphs.

Just add a call to guide_legend() into your graph.

ggplot(...) + ... + guide_legend(title="my awesome title")

As shown in the very nice ggplot docs.

If that doesn't work, you can more precisely set your guide parameters with a call to guides:

ggplot(...) + ... + guides(fill=guide_legend("my awesome title"))

You can also vary the shape/color/size by specifying these parameters for your call to guides as well.

The simple way is to use OFFSET. Not only second, any position we can query using offset.

SELECT SALARY,NAME FROM EMPLOYEE ORDER BY SALARY DESC LIMIT 1 OFFSET 1 --Second largest

SELECT SALARY,NAME FROM EMPLOYEE ORDER BY SALARY DESC LIMIT 1 OFFSET 9 --For 10th largest

img {
    float:left;
}
h3 {
    float:right;
}

jsFiddle example

Note that you will probably want to use the style clear:both on whatever elements comes after the code you provided so that it doesn't slide up directly beneath the floated elements.

Even later answer, but I wrote an Android Image Manager that handles caching transparently (memory and disk). The code is on Github https://github.com/felipecsl/Android-ImageManager

It has a default indent/padding so that the bullets will not end up outside the list itself.

A CSS reset might or might not contain rules to reset the list, that would depend on which one you use.

on body tag's onLoad try setting it like

document.getElementById("subEmail").style.backgroundColor = "yellow";

and after that on change of that input field check if some value is there, or paint it yellow like

function checkFilled() {
var inputVal = document.getElementById("subEmail");
if (inputVal.value == "") {
    inputVal.style.backgroundColor = "yellow";
            }
    }

coll.Reverse().Take(N).Reverse().ToList();


public static IEnumerable<T> TakeLast<T>(this IEnumerable<T> coll, int N)
{
    return coll.Reverse().Take(N).Reverse();
}

UPDATE: To address clintp's problem: a) Using the TakeLast() method I defined above solves the problem, but if you really want the do it without the extra method, then you just have to recognize that while Enumerable.Reverse() can be used as an extension method, you aren't required to use it that way:

List<string> mystring = new List<string>() { "one", "two", "three" }; 
mystring = Enumerable.Reverse(mystring).Take(2).Reverse().ToList();

In your code:

while(fscanf(fp,"%s %c",item,&status) == 1)  

why 1 and not 2? The scanf functions return the number of objects read.

In python there is no difference between modules and scripts; You can execute both scripts and modules. The file must be on the pythonpath AFAIK because python must be able to find the file in question. If python is executed from a directory, then the directory is automatically added to the pythonpath.

Refer to What is the best way to call a Python script from another Python script? for more information about modules vs scripts

There is also a builtin function execfile(filename) that will do what you want

This task can also be solved with a different approach. Instead of programming a converter and enlarging the code in the XAML, you can also aggregate the various parameters in the ViewModel. As a result, the ViewModel then has one more property that contains all parameters.

An example of my current application, which also let me deal with the topic. A generic RelayCommand is required: https://stackoverflow.com/a/22286816/7678085

The ViewModelBase is extended here by a command SaveAndClose. The generic type is a named tuple that represents the various parameters.

public ICommand SaveAndCloseCommand => saveAndCloseCommand ??= new RelayCommand<(IBaseModel Item, Window Window)>
    (execute =>
    {
        execute.Item.Save();
        execute.Window?.Close(); // if NULL it isn't closed.
    },
    canExecute =>
    {
        return canExecute.Item?.IsItemValide ?? false;
    });
private ICommand saveAndCloseCommand;

Then it contains a property according to the generic type:

public (IBaseModel Item, Window Window) SaveAndCloseParameter 
{ 
    get => saveAndCloseParameter ; 
    set 
    {
        SetProperty(ref saveAndCloseParameter, value);
    }
}
private (IBaseModel Item, Window Window) saveAndCloseParameter;

The XAML code of the view then looks like this: (Pay attention to the classic click event)

<Button 
    Command="{Binding SaveAndCloseCommand}" 
    CommandParameter="{Binding SaveAndCloseParameter}" 
    Click="ButtonApply_Click" 
    Content="Apply"
    Height="25" Width="100" />
<Button 
    Command="{Binding SaveAndCloseCommand}" 
    CommandParameter="{Binding SaveAndCloseParameter}" 
    Click="ButtonSave_Click" 
    Content="Save"
    Height="25" Width="100" />

and in the code behind of the view, then evaluating the click events, which then set the parameter property.

private void ButtonApply_Click(object sender, RoutedEventArgs e)
{
    computerViewModel.SaveAndCloseParameter = (computerViewModel.Computer, null);
}

private void ButtonSave_Click(object sender, RoutedEventArgs e)
{
    computerViewModel.SaveAndCloseParameter = (computerViewModel.Computer, this);
}

Personally, I think that using the click events is not a break with the MVVM pattern. The program flow control is still located in the area of ??the ViewModel.

To add to the existing answers, you can avoid affecting the URL by overriding the link with JavaScript. This will still take you to the top of the page without JavaScript, but will append # to the URL.

<a href="#" onclick="document.body.scrollTop=0;document.documentElement.scrollTop=0;event.preventDefault()">Back to top</a>

Use string's split() method.

states.split()

Cascade will work when you delete something on table Courses. Any record on table BookCourses that has reference to table Courses will be deleted automatically.

But when you try to delete on table BookCourses only the table itself is affected and not on the Courses

follow-up question: why do you have CourseID on table Category?

Maybe you should restructure your schema into this,

CREATE TABLE Categories 
(
  Code CHAR(4) NOT NULL PRIMARY KEY,
  CategoryName VARCHAR(63) NOT NULL UNIQUE
);

CREATE TABLE Courses 
(
  CourseID INT NOT NULL PRIMARY KEY,
  BookID INT NOT NULL,
  CatCode CHAR(4) NOT NULL,
  CourseNum CHAR(3) NOT NULL,
  CourseSec CHAR(1) NOT NULL,
);

ALTER TABLE Courses
ADD FOREIGN KEY (CatCode)
REFERENCES Categories(Code)
ON DELETE CASCADE;

This works for me

   <script type="text/javascript">
        var c = document.getElementById("<%=TextBox1.ClientID %>");
        c.select =
        function (event, ui) 
        { this.value = ""; return false; }
    </script>

Right click properties, Application tab, then see the assembly name and default namespace

Before you use DecimalFormat you need to use the following import or your code will not work:

import java.text.DecimalFormat;

The code for formatting is:

DecimalFormat precision = new DecimalFormat("0.00"); 
// dblVariable is a number variable and not a String in this case
txtTextField.setText(precision.format(dblVariable));

You probably haven't installed GLUT:

1. Install GLUT If you do not have GLUT installed on your machine you can download it from: http://www.xmission.com/~nate/glut/glut-3.7.6-bin.zip (or whatever version) GLUT Libraries and header files are • glut32.lib • glut.h

Source: http://cacs.usc.edu/education/cs596/OGL_Setup.pdf

EDIT:

The quickest way is to download the latest header, and compiled DLLs for it, place it in your system32 folder or reference it in your project. Version 3.7 (latest as of this post) is here: http://www.opengl.org/resources/libraries/glut/glutdlls37beta.zip

Folder references:

glut.h: 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\GL\'
glut32.lib: 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib\'
glut32.dll: 'C:\Windows\System32\'

For 64-bit machines, you will want to do this.
glut32.dll: 'C:\Windows\SysWOW64\'

Same pattern applies to freeglut and GLEW files with the header files in the GL folder, lib in the lib folder, and dll in the System32 (and SysWOW64) folder.
1. Under Visual C++, select Empty Project.
2. Go to Project -> Properties. Select Linker -> Input then add the following to the Additional Dependencies field:
opengl32.lib
glu32.lib
glut32.lib

Each controller has it's own scope(s) so that's causing your issue.

Having two controllers that want access to the same data is a classic sign that you want a service. The angular team recommends thin controllers that are just glue between views and services. And specifically- "services should hold shared state across controllers".

Happily, there's a nice 15-minute video describing exactly this (controller communication via services): video

One of the original author's of Angular, Misko Hevery, discusses this recommendation (of using services in this situation) in his talk entitled Angular Best Practices (skip to 28:08 for this topic, although I very highly recommended watching the whole talk).

You can use events, but they are designed just for communication between two parties that want to be decoupled. In the above video, Misko notes how they can make your app more fragile. "Most of the time injecting services and doing direct communication is preferred and more robust". (Check out the above link starting at 53:37 to hear him talk about this)

This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through.

It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again):

Needless to say use of this "feature" is a bad idea and is unsafe - hence the name.

You should find out why the site is showing the error and/or stop using it until they fix it. HSTS specifically adds protections for bad certs to prevent you clicking through them. The fact it's needed suggests there is something wrong with the https connection - like the site or your connection to it has been hacked.

The chrome developers also do change this periodically. They changed it recently from badidea to thisisunsafe so everyone using badidea, suddenly stopped being able to use it. You should not depend on it. As Steffen pointed out in the comments below, it is available in the code should it change again though they now base64 encode it to make it more obscure. The last time they changed they put this comment in the commit:

Rotate the interstitial bypass keyword

The security interstitial bypass keyword hasn't changed in two years and awareness of the bypass has been increased in blogs and social media. Rotate the keyword to help prevent misuse.

I think the message from the Chrome team is clear - you should not use it. It would not surprise me if they removed it completely in future.

If you are using this when using a self-signed certificate for local testing then why not just add your self-signed certificate certificate to your computer's certificate store so you get a green padlock and do not have to type this? Note Chrome insists on a SAN field in certificates now so if just using the old subject field then even adding it to the certificate store will not result in a green padlock.

If you leave the certificate untrusted then certain things do not work. Caching for example is completely ignored for untrusted certificates. As is HTTP/2 Push.

HTTPS is here to stay and we need to get used to using it properly - and not bypassing the warnings with a hack that is liable to change and doesn't work the same as a full HTTPS solution.

It is a simple 3 Step Process :

1. Go to your private repo and click on settings
2. To the left of the screen click on Manage access
3. Then Click on Invite Collaborator

This, but also - the invited user needs to be logged in to Github before clicking the invitation link in their email or they'll get a 404 error.

Try with

f.mkdirs() then createNewFile()

try as this code.

$.ajax({
        type: "POST",
        url: "http://rt.ja.com/includes/register.php?submit=1",
        data: "username="+username+"&email="+email+"&password="+password+"&passconf="+passconf,

        success: function(html)
        {   
            //alert(html);
            $('#userError').html(html);
            $("#userError").html(userChar);
            $("#userError").html(userTaken);
        }
    });

i think this will work definitely..

you can also use .serialize() function for sending data via jquery Ajax..

i.e: data : $("#registerSubmit").serialize()

Thanks.

I'm pretty sure the classpath and the shared library search path have little to do with each other. According to The JNI Book (which admittedly is old), on Windows if you do not use the java.library.path system property, the DLL needs to be in the current working directory or in a directory listed in the Windows PATH environment variable.

Update:

Looks like Oracle has removed the PDF from its website. I've updated the link above to point to an instance of the PDF living at University of Texas - Arlington.

Also, you can also read Oracle's HTML version of the JNI Specification. That lives in the Java 8 section of the Java website and so hopefully will be around for a while.

Update 2:

At least in Java 8 (I haven't checked earlier versions) you can do:

java -XshowSettings:properties -version

to find the shared library search path. Look for the value of the java.library.path property in that output.

preg_match("/^-?\d+[\.]?\d\d$/", $sum)

If by configure release/build, you mean you only need one config per makefile, then it is simply a matter and decoupling CC and CFLAGS:

CFLAGS=-DDEBUG
#CFLAGS=-O2 -DNDEBUG
CC=g++ -g3 -gdwarf2 $(CFLAGS)

Depending on whether you can use gnu makefile, you can use conditional to make this a bit fancier, and control it from the command line:

DEBUG ?= 1
ifeq ($(DEBUG), 1)
    CFLAGS =-DDEBUG
else
    CFLAGS=-DNDEBUG
endif

.o: .c
    $(CC) -c $< -o $@ $(CFLAGS)

and then use:

make DEBUG=0
make DEBUG=1

If you need to control both configurations at the same time, I think it is better to have build directories, and one build directory / config.

You don't need to change port number for your application, just configure your www server (nginx or apache) to proxy queries to flask port. Pay attantion on uWSGI.

A Type Initializer exception indicates that the type couldn't be created. This would occur typically right before your call to your method when you simply reference that class.

Is the code you have here the complete text of your type? I would be looking for something like an assignment to fail. I see this a lot with getting app settings and things of that nature.

static class RHelper
{
     //If this line of code failed, you'd get this error
     static string mySetting = Settings.MySetting;
} 

You can also see this with static constructors for types.

In any case, is there any more to this class?

For anyone else who gets caught, ensure setCustomAnimations is called before the call to replace/add when building the transaction.

Somehow I got it to work by using margin-right, and setting it to move from right to left. http://jsfiddle.net/gXdMc/

Don't know why for this case, margin-right 100% doesn't go off the screen. :D (tested on chrome 18)

EDIT: now left to right works too http://jsfiddle.net/6LhvL/

Better yet, put --user-install in your ~/.gemrc file so you don't have to type it every time

gem: --user-install

ALTER TABLE TABLE_NAME ADD (COLUMN_NAME_NEW varchar2(4000 char));
update TABLE_NAME set COLUMN_NAME_NEW = COLUMN_NAME;

ALTER TABLE TABLE_NAME DROP COLUMN COLUMN_NAME;
ALTER TABLE TABLE_NAME rename column COLUMN_NAME_NEW to COLUMN_NAME;

if you can control creating/passing the settings object, i'd recommend using an ExpandoObject instead.

dynamic settings = new ExpandoObject();
settings.Filename = "asdf.txt";
settings.Size = 10;
...

function void Settings(dynamic settings)
{
    if ( ((IDictionary<string, object>)settings).ContainsKey("Filename") )
        .... do something ....
}

you can easily do like this:-

    <table>
    <thead>
        <tr>
          <th bgcolor="#5D7B9D"><font color="#fff">Header 1</font></th>
          <th bgcolor="#5D7B9D"><font color="#fff">Header 2</font></th>
           <th bgcolor="#5D7B9D"><font color="#fff">Header 3</font></th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>blah blah</td>
            <td>blah blah</td>
            <td>blah blah</td>
        </tr>
    </tbody>
</table>

For me, my certificate is expired. I have created a new certificate.

If HELLO is your String then you can't change HELLO to HILLO. This property is called immutability property.

You can have multiple pointer String variable to point HELLO String.

But if HELLO is char Array then you can change HELLO to HILLO. Eg,

char[] charArr = 'HELLO';
char[1] = 'I'; //you can do this

Answer:

Programming languages have immutable data variables so that it can be used as keys in key, value pair. String variables are used as keys/indices, so they are immutable.

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

I was getting same errors after an install on Windows 10. And I tried restarting but it did not work, so I did the following (do not recommend if you have been working in docker for awhile, this was on a fresh install):

1) Find the whale in your system tray, and right click

2) Go to settings > Reset

3) Reset to factory defaults

I was then able to follow the starting docker tutorial on the website with Windows 10, and now it works like a charm.

Short answer:

use a non-blocking recv(), or a blocking recv() / select() with a very short timeout.

Long answer:

The way to handle socket connections is to read or write as you need to, and be prepared to handle connection errors.

TCP distinguishes between 3 forms of "dropping" a connection: timeout, reset, close.

Of these, the timeout can not really be detected, TCP might only tell you the time has not expired yet. But even if it told you that, the time might still expire right after.

Also remember that using shutdown() either you or your peer (the other end of the connection) may close only the incoming byte stream, and keep the outgoing byte stream running, or close the outgoing stream and keep the incoming one running.

So strictly speaking, you want to check if the read stream is closed, or if the write stream is closed, or if both are closed.

Even if the connection was "dropped", you should still be able to read any data that is still in the network buffer. Only after the buffer is empty will you receive a disconnect from recv().

Checking if the connection was dropped is like asking "what will I receive after reading all data that is currently buffered ?" To find that out, you just have to read all data that is currently bufferred.

I can see how "reading all buffered data", to get to the end of it, might be a problem for some people, that still think of recv() as a blocking function. With a blocking recv(), "checking" for a read when the buffer is already empty will block, which defeats the purpose of "checking".

In my opinion any function that is documented to potentially block the entire process indefinitely is a design flaw, but I guess it is still there for historical reasons, from when using a socket just like a regular file descriptor was a cool idea.

What you can do is:

• set the socket to non-blocking mode, but than you get a system-depended error to indicate the receive buffer is empty, or the send buffer is full
• stick to blocking mode but set a very short socket timeout. This will allow you to "ping" or "check" the socket with recv(), pretty much what you want to do
• use select() call or asyncore module with a very short timeout. Error reporting is still system-specific.

For the write part of the problem, keeping the read buffers empty pretty much covers it. You will discover a connection "dropped" after a non-blocking read attempt, and you may choose to stop sending anything after a read returns a closed channel.

I guess the only way to be sure your sent data has reached the other end (and is not still in the send buffer) is either:

• receive a proper response on the same socket for the exact message that you sent. Basically you are using the higher level protocol to provide confirmation.
• perform a successful shutdow() and close() on the socket

The python socket howto says send() will return 0 bytes written if channel is closed. You may use a non-blocking or a timeout socket.send() and if it returns 0 you can no longer send data on that socket. But if it returns non-zero, you have already sent something, good luck with that :)

Also here I have not considered OOB (out-of-band) socket data here as a means to approach your problem, but I think OOB was not what you meant.

None of the previous solutions worked for me. Finally I found that the action should be coded as:

public ActionResult Index(string MyCheck = null)

and then, when checked the passed value was "on", not "true". Else, it is always null.

Hope it helps somebody!

./gradlew

Your directory with gradlew is not included in the PATH, so you must specify path to the gradlew. . means "current directory".

The official tutorial discusses deploying an app to production. One option is to use Waitress, a production WSGI server. Other servers include Gunicorn and uWSGI.

When running publicly rather than in development, you should not use the built-in development server (flask run). The development server is provided by Werkzeug for convenience, but is not designed to be particularly efficient, stable, or secure.

Instead, use a production WSGI server. For example, to use Waitress, first install it in the virtual environment:

$ pip install waitress

You need to tell Waitress about your application, but it doesn’t use FLASK_APP like flask run does. You need to tell it to import and call the application factory to get an application object.

$ waitress-serve --call 'flaskr:create_app'
Serving on http://0.0.0.0:8080

Or you can use waitress.serve() in the code instead of using the CLI command.

from flask import Flask

app = Flask(__name__)

@app.route("/")
def index():
    return "<h1>Hello!</h1>"

if __name__ == "__main__":
    from waitress import serve
    serve(app, host="0.0.0.0", port=8080)

$ python hello.py

To count the commits for the branch you are on:

git rev-list --count HEAD

for a branch

git rev-list --count <branch-name>

If you want to count the commits on a branch that are made since you created the branch

git rev-list --count HEAD ^<branch-name>

This will count all commits ever made that are not on the branch-name as well.

Examples

git checkout master
git checkout -b test
<We do 3 commits>
git rev-list --count HEAD ^master

Result: 3

If your branch comes of a branch called develop:

git checkout develop
git checkout -b test
<We do 3 commits>
git rev-list --count HEAD ^develop

Result: 3

Ignoring Merges

If you merge another branch into the current branch without fast forward and you do the above, the merge is also counted. This is because for git a merge is a commit.

If you don't want to count these commits add --no-merges:

git rev-list --no-merges --count HEAD ^develop

I don't know if javaw will write to the %errorlevel% variable, but it might.

echo %errorlevel% after you run it directly to see.

Other than that, you can pipe the output of javaw to a file, then use find to see what the results were. Without knowing the output of it, I can't really help you with that.

I've been attempting to set the current row to the first index (dealing with primary keys). I would suggest

if(rs.absolute(1)){
    System.out.println("We have data");
} else {
    System.out.println("No data");
}

When the ResultSet is populated, it points to before the first row. When setting it to the first row (indicated by rs.absolute(1)) it will return true denoting it was successfully placed at row 1, or false if the row does not exist. We can extrapolate this to

for(int i=1; rs.absolute(i); i++){
    //Code
}

which sets the current row to position i and will fail if the row doesn't exist. This is just an alternative method to

while(rs.next()){
    //Code
}

Keeping the below statements in head tag fixed this issue

<style type="text/css">

    display: none !important;
}

I suspect GCC (mingw) has custom code to disable the checks for the wide printf functions on Windows. This is because Microsoft's own implementation (MSVCRT) is badly wrong and has %s and %ls backwards for the wide printf functions; since GCC can't be sure whether you will be linking with MS's broken implementation or some corrected one, the least-obtrusive thing it can do is just shut off the warning.

I found the following worked for me (revert a single file to pre-merge state):

git reset *currentBranchIntoWhichYouMerged* -- *fileToBeReset*

Because of things like this, as a general rule of thumb, I try to avoid as much XAML "trickery" as possible and keep the XAML as dumb and simple as possible and do the rest in the ViewModel (or attached properties or IValueConverters etc. if really necessary).

If possible I would give the ViewModel of the current DataContext a reference (i.e. property) to the relevant parent ViewModel

public class ThisViewModel : ViewModelBase
{
    TypeOfAncestorViewModel Parent { get; set; }
}

and bind against that directly instead.

<TextBox Text="{Binding Parent}" />

You could reference the variable in an assertion and then build with -fsanitize=address:

void foo (int32_t& i) {
    // Assertion will trigger address sanitizer if not initialized:
    assert(static_cast<int64_t>(i) != INT64_MAX);
}

This will cause the program to reliably crash with a stack trace (as opposed to undefined behavior).

Sometimes it's knowing what to ask. I didn't know as I am a developer who has taken on some DevOps work.

Apparently 'passwordless' or NOPASSWD login is a thing which you need to put in the /etc/sudoers file.

The answer to my question is at Ansible: best practice for maintaining list of sudoers.

The Ansible playbook code fragment looks like this from my problem:

- name: Make sure we have a 'wheel' group
  group:
    name: wheel
    state: present

- name: Allow 'wheel' group to have passwordless sudo
  lineinfile:
    dest: /etc/sudoers
    state: present
    regexp: '^%wheel'
    line: '%wheel ALL=(ALL) NOPASSWD: ALL'
    validate: 'visudo -cf %s'

- name: Add sudoers users to wheel group
  user:
    name=deployer
    groups=wheel
    append=yes
    state=present
    createhome=yes

- name: Set up authorized keys for the deployer user
  authorized_key: user=deployer key="{{item}}"
  with_file:
    - /home/railsdev/.ssh/id_rsa.pub

And the best part is that the solution is idempotent. It doesn't add the line

%wheel ALL=(ALL) NOPASSWD: ALL

to /etc/sudoers when the playbook is run a subsequent time. And yes...I was able to ssh into the server as "deployer" and run sudo commands without having to give a password.

This can be done with an enum and a helper method:

enum LogLevel {
    TRACE,
    DEBUG,
    INFO,
    WARN,
    ERROR,
}

public static void log(Logger logger, LogLevel level, String format, Object[] argArray) {
    switch (level) {
        case TRACE:
            logger.trace(format, argArray);
            break;
        case DEBUG:
            logger.debug(format, argArray);
            break;
        case INFO:
            logger.info(format, argArray);
            break;
        case WARN:
            logger.warn(format, argArray);
            break;
        case ERROR:
            logger.error(format, argArray);
            break;
    }
}

// example usage:
private static final Logger logger = ...
final LogLevel level = ...
log(logger, level, "Something bad happened", ...);

You could add other variants of log, say if you wanted generic equivalents of SLF4J's 1-parameter or 2-parameter warn/error/etc. methods.

In a real world environment it's never a good idea to work solely with time, always use datetime, even better utc, to avoid conflicts like overnight, daylight saving, different timezones between user and server etc.

So I'd recommend this approach:

import datetime as dt

_now = dt.datetime.now()  # or dt.datetime.now(dt.timezone.utc)
_in_5_sec = _now + dt.timedelta(seconds=5)

# get '14:39:57':
_in_5_sec.strftime('%H:%M:%S')

Please check this example here: Accessing Structure Members

There is explained that the right way to do it is like this:

strcpy(s1.name , "Egzona");
printf( "Name : %s\n", s1.name);

Here is an example, you can modify the method to accept a string parameter. Then just save the image object with image.Save(...).

public Image LoadImage()
{
    //data:image/gif;base64,
    //this image is a single pixel (black)
    byte[] bytes = Convert.FromBase64String("R0lGODlhAQABAIAAAAAAAAAAACH5BAAAAAAALAAAAAABAAEAAAICTAEAOw==");

    Image image;
    using (MemoryStream ms = new MemoryStream(bytes))
    {
        image = Image.FromStream(ms);
    }

    return image;
}

It is possible to get an exception A generic error occurred in GDI+. when the bytes represent a bitmap. If this is happening save the image before disposing the memory stream (while still inside the using statement).

Delete '.git/config' and try again. Attention this will may reset some git settings too!

I've tried alternative credentials and Personal Access Token for many times with right credential and it kept telling me "fatal: Authentication failed".

Finally, I found there is a file named ".git/config" located at the root of my Repo. I deleted this file and type in my credentials again, it worked.

Yes, don't Test private methods.... The idea of a unit test is to test the unit by its public 'API'.

If you are finding you need to test a lot of private behavior, most likely you have a new 'class' hiding within the class you are trying to test, extract it and test it by its public interface.

One piece of advice / Thinking tool..... There is an idea that no method should ever be private. Meaning all methods should live on a public interface of an object.... if you feel you need to make it private, it most likely lives on another object.

This piece of advice doesn't quite work out in practice, but its mostly good advice, and often it will push people to decompose their objects into smaller objects.

As "there are tens of thousands of cells in the page" binding the click-event to every single cell will cause a terrible performance problem. There's a better way to do this, that is binding a click event to the body & then finding out if the cell element was the target of the click. Like this:

$('body').click(function(e){
       var Elem = e.target;
       if (Elem.nodeName=='td'){
           //.... your business goes here....
           // remember to replace $(this) with $(Elem)
       }
})

This method will not only do your task with native "td" tag but also with later appended "td". I think you'll be interested in this article about event binding & delegate

Or you can simply use the ".on()" method of jQuery with the same effect:

$('body').on('click', 'td', function(){
        ...
});

I think it's better to use the Microsoft.VisualBasic.FileIO.TextFieldParser Class if you're working with comma separated values text files.

The problem here is that the link sits behind the button, even when changing the z-index. This markup is also invalid (read the spec). So the reason the links dont work is because you are actually clicking the button and not the link. The solution is to change your markup around.

<button type="button"><a href="yourlink">Link</a></button>

Then style as needed. A demo is here.

you can use

return false; or return; within your condition.

function refreshGrid(entity) {
    var store = window.localStorage;
    var partitionKey;
    ....
    if(some_condition) {
      return false;
    }
}

While I agree with everyone else, if you are dead set on using frames anyway, you can just do index.html in XHTML and then do the contents of the frames in HTML5.

You need to enter the width % for each cell. But wait, there's a better way to do that, it's called CSS:

<style>
     .equalDivide tr td { width:25%; }
</style>

<table class="equalDivide" cellpadding="0" cellspacing="0" width="100%" border="0">
   <tr>
      <td></td>
      <td></td>
      <td></td>
      <td></td>
   </tr>
</table>

You can look here Can the key in a Java property include a blank character?

for escape equal '=' \u003d

table.whereclause=where id=100

key:[table.whereclause] value:[where id=100]

table.whereclause\u003dwhere id=100

key:[table.whereclause=where] value:[id=100]

table.whereclause\u003dwhere\u0020id\u003d100

key:[table.whereclause=where id=100] value:[]

data[10] = {10,20,30,40,50,60,71,80,90,91};

The above is not correct (syntax error). It means you are assigning an array to data[10] which can hold just an element.

If you want to initialize an array, try using Array Initializer:

int[] data = {10,20,30,40,50,60,71,80,90,91};

// or

int[] data;
data = new int[] {10,20,30,40,50,60,71,80,90,91};

Notice the difference between the two declarations. When assigning a new array to a declared variable, new must be used.

Even if you correct the syntax, accessing data[10] is still incorrect (You can only access data[0] to data[9] because index of arrays in Java is 0-based). Accessing data[10] will throw an ArrayIndexOutOfBoundsException.

Turn on the credential helper so that Git will save your password in memory for some time:

In Terminal, enter the following:

# Set git to use the credential memory cache
git config --global credential.helper cache

By default, Git will cache your password for 15 minutes.

To change the default password cache timeout, enter the following:

# Set the cache to timeout after 1 hour (setting is in seconds)
git config --global credential.helper 'cache --timeout=3600'

Javascript file using jQuery (cleaner but library overhead):

$.ajax({
    type: 'POST',
    url: 'process.php',
    data: {json: JSON.stringify(json_data)},
    dataType: 'json'
});

PHP file (process.php):

directions = json_decode($_POST['json']);
var_dump(directions);

Note that if you use callback functions in your javascript:

$.ajax({
    type: 'POST',
    url: 'process.php',
    data: {json: JSON.stringify(json_data)},
    dataType: 'json'
})
.done( function( data ) {
    console.log('done');
    console.log(data);
})
.fail( function( data ) {
    console.log('fail');
    console.log(data);
});

You must, in your PHP file, return a JSON object (in javascript formatting), in order to get a 'done/success' outcome in your Javascript code. At a minimum return/print:

print('{}');

See Ajax request return 200 OK but error event is fired instead of success

Although for anything a bit more serious you should be sending back a proper header explicitly with the appropriate response code.

You can't with inline styling alone. Do not recommend reimplementing CSS features in JavaScript we already have a language that is extremely powerful and incredibly fast built for this use case -- CSS. So use it! Made Style It to assist.

It's worth noting, on top of these other answers, that C++20 solves one of the problems that enum class has: verbosity. Imagining a hypothetical enum class, Color.

void foo(Color c)
  switch (c) {
    case Color::Red: ...;
    case Color::Green: ...;
    case Color::Blue: ...;
    // etc
  }
}

This is verbose compared to the plain enum variation, where the names are in the global scope and therefore don't need to be prefixed with Color::.

However, in C++20 we can use using enum to introduce all of the names in an enum to the current scope, solving the problem.

void foo(Color c)
  using enum Color;
  switch (c) {
    case Red: ...;
    case Green: ...;
    case Blue: ...;
    // etc
  }
}

So now, there is no reason not to use enum class.

c is a double variable, but the value being assigned to it is an int value because it results from the division of two ints, which gives you "integer division" (dropping the remainder). So what happens in the line c=a/b is

1. a/b is evaluated, creating a temporary of type int
2. the value of the temporary is assigned to c after conversion to type double.

The value of a/b is determined without reference to its context (assignment to double).

You can use getTime() method to convert the Date to the number of milliseconds since January 1, 1970. Then you can easy do any arithmetic operations with the dates. Of course you can convert the number back to the Date with setTime(). See here an example.
