Use

Time.now + 10.days

or even

10.days.from_now

Both definitely work. Are you sure you're in Rails and not just Ruby?

If you definitely are in Rails, where are you trying to run this from? Note that Active Support has to be loaded.

There is actually a nice Gem called local_time by basecamp to do all of that on client side only, I believe:

https://github.com/basecamp/local_time

I couldn't get the form suggested by @thoredge to work in Gradle 1.11, but this works for me:

home = System.getenv('HOME')

It helps to keep in mind that anything that works in pure Java will work in Gradle too.

For System.Timers.Timer, on separate thread, if SynchronizingObject is not set.

    static System.Timers.Timer DummyTimer = null;

    static void Main(string[] args)
    {
        try
        {

            Console.WriteLine("Main Thread Id: " + System.Threading.Thread.CurrentThread.ManagedThreadId);

            DummyTimer = new System.Timers.Timer(1000 * 5); // 5 sec interval
            DummyTimer.Enabled = true;
            DummyTimer.Elapsed += new System.Timers.ElapsedEventHandler(OnDummyTimerFired);
            DummyTimer.AutoReset = true;

            DummyTimer.Start();

            Console.WriteLine("Hit any key to exit");
            Console.ReadLine();
        }
        catch (Exception Ex)
        {
            Console.WriteLine(Ex.Message);
        }

        return;
    }

    static void OnDummyTimerFired(object Sender, System.Timers.ElapsedEventArgs e)
    {
        Console.WriteLine(System.Threading.Thread.CurrentThread.ManagedThreadId);
        return;
    }

Output you'd see if DummyTimer fired on 5 seconds interval:

Main Thread Id: 9
   12
   12
   12
   12
   12
   ... 

So, as seen, OnDummyTimerFired is executed on Workers thread.

No, further complication - If you reduce interval to say 10 ms,

Main Thread Id: 9
   11
   13
   12
   22
   17
   ... 

This is because if prev execution of OnDummyTimerFired isn't done when next tick is fired, then .NET would create a new thread to do this job.

Complicating things further, "The System.Timers.Timer class provides an easy way to deal with this dilemma—it exposes a public SynchronizingObject property. Setting this property to an instance of a Windows Form (or a control on a Windows Form) will ensure that the code in your Elapsed event handler runs on the same thread on which the SynchronizingObject was instantiated."

I have the same problem here, then I reinstalled mysql and it worked.

sudo apt-get install mysql-server mysql-common mysql-client

You can use these queries:

select * from all_tab_privs;
select * from dba_sys_privs;
select * from dba_role_privs;

Each of these tables have a grantee column, you can filter on that in the where criteria:

where grantee = 'A'

To query privileges on objects (e.g. tables) in other schema I propose first of all all_tab_privs, it also has a table_schema column.

If you are logged in with the same user whose privileges you want to query, you can use user_tab_privs, user_sys_privs, user_role_privs. They can be queried by a normal non-dba user.

In your input tag, place the following:

onFocus="this.select()"

The GET (and HEAD) method should never be used to do anything that has side-effects. A side-effect might be updating the state of a web application, or it might be charging your credit card. If an action has side-effects another method (POST) should be used instead.

So, a user (or their browser) shouldn't be held accountable for something done by a GET. If some harmful or expensive side-effect occurred as the result of a GET, that would be the fault of the web application, not the user. According to the spec, a user agent must not automatically follow a redirect unless it is a response to a GET or HEAD request.

Of course, a lot of GET requests do have some side-effects, even if it's just appending to a log file. The important thing is that the application, not the user, should be held responsible for those effects.

The relevant sections of the HTTP spec are 9.1.1 and 9.1.2, and 10.3.

Yes, there is a way. Two in fact. In October 2013 jshint added a way to ignore blocks of code like this:

// Code here will be linted with JSHint.
/* jshint ignore:start */
// Code here will be ignored by JSHint.
/* jshint ignore:end */
// Code here will be linted with JSHint.

You can also ignore a single line with a trailing comment like this:

ignoreThis(); // jshint ignore:line

Just want to add this. I had this problem today. Adjusted the settings in my project, rebuilt, and same problem. I had (incorrectly) assumed that changing the settings in my project (Eclipse) would cause the projects on which my project depends to be recompiled also. Adjusting the settings to all of the projects up the dependency tree solved the problem.

Create a function to move it:

function move_file($file, $to){
    $path_parts = pathinfo($file);
    $newplace   = "$to/{$path_parts['basename']}";
    if(rename($file, $newplace))
        return $newplace;
    return null;
}

You can use either one of these to check null, whitespace and empty strings.

WHERE COLUMN <> '' 

WHERE LEN(COLUMN) > 0

WHERE NULLIF(LTRIM(RTRIM(COLUMN)), '') IS NOT NULL

#!/bin/bash
logPath="pinglog.txt"

while(true)
      do
          # refresh the timestamp before each ping attempt
          theTime=$(date -Iseconds)

          # refresh the ping variable
          ping google.com -n 1

            if [ $? -eq 0 ] 
            then
                 echo $theTime + '| connection is up' >> $logPath
            else
                 echo $theTime + '| connection is down' >> $logPath
          fi
            Sleep 1
             echo ' '
      done

 for(int i=0;i<ytFiles.size();i++){

                    int key = ytFiles.keyAt(i);
                    Log.e("key", String.valueOf(key));
                    String format = ytFiles.get(key).getFormat().toString();
                    String url = ytFiles.get(key).getUrl();
                    Log.e("url",url);
                }

you can get key by method keyat and you have to pass the index then it will return key at that particular index. this loop will get all the key

This solutions sounds crazy, but works smooth as honey

import csv

with open('filename', 'wb') as myfile:
    wr = csv.writer(myfile, quoting=csv.QUOTE_ALL,delimiter='\n')
    wr.writerow(mylist)

The file is being written by csvwriter hence csv properties are maintained i.e. comma separated. The delimiter helps in the main part by moving list items to next line, each time.

I prefer the OO approach:

$date = new \DateTimeImmutable('today'); //'today' gives midnight, leave blank for current time.
$futureDate = $date->add(\DateInterval::createFromDateString('+1 Year'))

Use DateTimeImmutable otherwise you will modify the original date too! more on DateTimeImmutable: http://php.net/manual/en/class.datetimeimmutable.php

If you just want from todays date then you can always do:

new \DateTimeImmutable('-1 Month');

Based on the good solution that provided by tazo todua, I've made some of changes since mysql_connect has deprecated and not supported in new php version. I've used mysqli_connect instead and increased the performance of inserting values to the database:

The X-Frame-Options header is a security feature enforced at the browser level.

If you have control over your user base (IT dept for corp app), you could try something like a greasemonkey script (if you can a) deploy greasemonkey across everyone and b) deploy your script in a shared way)...

Alternatively, you can proxy their result. Create an endpoint on your server, and have that endpoint open a connection to the target endpoint, and simply funnel traffic backwards.

If you added "spring-boot-starter-data-jpa" dependency in pom.xml, Please add respective database in dependency like h2 and etc.

Replace double quotes with single ones:

INSERT
INTO    MY.LOGFILE
        (id,severity,category,logdate,appendername,message,extrainfo)
VALUES  (
       'dee205e29ec34',
       'FATAL',
       'facade.uploader.model',
       '2013-06-11 17:16:31',
       'LOGDB',
       NULL,
       NULL
       )

In SQL, double quotes are used to mark identifiers, not string constants.

May be using this query you don't get any result or empty result. You need to use OR instead of AND in your query like below.

$query = mysql_query("SELECT image_id FROM list WHERE (style_id = 24 AND style_value = 'red') OR (style_id = 25 AND style_value = 'big') OR (style_id = 27 AND style_value = 'round');

Try out this query.

Moment js solution to this is

var d = new Date(new Date().setHours(0,0,0,0));
m.add(m.utcOffset(), 'm')
m.toDate().toISOString()
// output "2019-07-18T00:00:00.000Z"

For Ubuntu xampp,
Go to /opt/lampp/etc/extra/
and open httpd-xampp.conf file and add below lines to get remote access,
    Order allow,deny
    Require all granted
    Allow from all

in /opt/lampp/phpmyadmin section.

And restart lampp using, /opt/lampp/lampp restart

Here is a modified version of the chosen answer:

getMonth("Feb")
function getMonth(month) {
  d = new Date().toString().split(" ")
  d[1] = month
  d = new Date(d.join(' ')).getMonth()+1
  if(!isNaN(d)) {
    return d
  }
  return -1;
}

This should work:

function validateUrl(value){_x000D_
 return /^(http(s)?:\/\/.)?(www\.)?[-a-zA-Z0-9@:%._\+~#=]{2,256}\.[a-z]{2,6}\b([-a-zA-Z0-9@:%_\+.~#?&//=]*)$/gi.test(value);_x000D_
}_x000D_
_x000D_
console.log(validateUrl('google.com')); // true_x000D_
console.log(validateUrl('www.google.com')); // true_x000D_
console.log(validateUrl('http://www.google.com')); // true_x000D_
console.log(validateUrl('http:/www.google.com')); // false_x000D_
console.log(validateUrl('www.google.com/test')); // true

You cant do it on shared hosting , Add ticket to support of hosting for same ( otherwise you can look for dedicated server where you can manage anything )

It's simple and understandable. Just copy paste this code and your issue will get resolved.For more conditions just change the value in pattern.and your work will done.

<input type="text"  pattern="[0-9]{0,}" oninvalid="this.setCustomValidity('Please enter only numeric value. Special character are not allowed.')" oninput="setCustomValidity('')">

Assuming you are currently on master:

git push origin master:master-old        # 1
git branch master-old origin/master-old  # 2
git reset --hard $new_master_commit      # 3
git push -f origin                       # 4

1. First make a master-old branch in the origin repository, based off of the master commit in the local repository.
2. Create a new local branch for this new origin/master-old branch (which will automatically be set up properly as a tracking branch).
3. Now point your local master to whichever commit you want it to point to.
4. Finally, force-change master in the origin repository to reflect your new local master.

(If you do it in any other way, you need at least one more step to ensure that master-old is properly set up to track origin/master-old. None of the other solutions posted at the time of this writing include that.)

A Simple Explanation:

1. Are you serializing data?

   Serialization is basically writing class data to a file/stream/etc. De-serialization is reading that data back to a class.

2. Do you intend to go into production?

   If you are just testing something with unimportant/fake data, then don't worry about it (unless you are testing serialization directly).

3. Is this the first version?

   If so, set serialVersionUID=1L.

4. Is this the second, third, etc. prod version?

   Now you need to worry about serialVersionUID, and should look into it in depth.

Basically, if you don't update the version correctly when you update a class you need to write/read, you will get an error when you try to read old data.

In your connection string replace server=localhost with "server = Paul-PC\\SQLEXPRESS;"

You should delete the file in the folder first , then the folder.This way you will recursively call the method.

var table = new DataTable();    
using (var da = new SqlDataAdapter("SELECT * FROM mytable", "connection string"))
{      
    da.Fill(table);
}

Below is the only CORRECT algorithm for converting sRGB images, as used in browsers etc., to grayscale.

It is necessary to apply an inverse of the gamma function for the color space before calculating the inner product. Then you apply the gamma function to the reduced value. Failure to incorporate the gamma function can result in errors of up to 20%.

For typical computer stuff, the color space is sRGB. The right numbers for sRGB are approx. 0.21, 0.72, 0.07. Gamma for sRGB is a composite function that approximates exponentiation by 1/(2.2). Here is the whole thing in C++.

// sRGB luminance(Y) values
const double rY = 0.212655;
const double gY = 0.715158;
const double bY = 0.072187;

// Inverse of sRGB "gamma" function. (approx 2.2)
double inv_gam_sRGB(int ic) {
    double c = ic/255.0;
    if ( c <= 0.04045 )
        return c/12.92;
    else 
        return pow(((c+0.055)/(1.055)),2.4);
}

// sRGB "gamma" function (approx 2.2)
int gam_sRGB(double v) {
    if(v<=0.0031308)
        v *= 12.92;
    else 
        v = 1.055*pow(v,1.0/2.4)-0.055;
    return int(v*255+0.5); // This is correct in C++. Other languages may not
                           // require +0.5
}

// GRAY VALUE ("brightness")
int gray(int r, int g, int b) {
    return gam_sRGB(
            rY*inv_gam_sRGB(r) +
            gY*inv_gam_sRGB(g) +
            bY*inv_gam_sRGB(b)
    );
}

Try to rename the package name and the class/jframe names... The clean and build the application.

1. Right Click on the package name
2. Go to Refactor
3. Select Rename
4. Give it a meaningful name, preferably all in small letters

5. Click on Refactor

   Do the same for the class/jframe names.

6. Last Select Run from Menu 7.Select Clean and build main project

That should do it!!! All best

Why did not anyone mention setOnTouchListener? Using setOnTouchListener is easy and all right, and just return true if the listener has consumed the event, false otherwise.

First, double check that the branch has been actually pushed remotely, by using the command git ls-remote origin. If the new branch appears in the output, try and give the command git fetch: it should download the branch references from the remote repository.

If your remote branch still does not appear, double check (in the ls-remote output) what is the branch name on the remote and, specifically, if it begins with refs/heads/. This is because, by default, the value of remote.<name>.fetch is:

+refs/heads/*:refs/remotes/origin/*

so that only the remote references whose name starts with refs/heads/ will be mapped locally as remote-tracking references under refs/remotes/origin/ (i.e., they will become remote-tracking branches)

As an alternative, you can make use of X-Forwarded-Proto header to force a redirect to HTTPS.

add these lines in the .htaccess file

### Force HTTPS
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

If anyone is strugling with the same problem I solved it by adding @EntityScan in my main class. Just add your model package to the basePackages property.

user Jochen Ritzel said this in a comment to an answer to this question from user dappawit. It should work:

('1' in var) and ('2' in var) and ('3' in var) ...

'1', '2', etc. should be replaced with the characters you are looking for.

See this page in the Python 2.7 documentation for some information on strings, including about using the in operator for substring tests.

Update: This does the same job as my above suggestion with less repetition:

# When looking for single characters, this checks for any of the characters...
# ...since strings are collections of characters
any(i in '<string>' for i in '123')
# any(i in 'a' for i in '123') -> False
# any(i in 'b3' for i in '123') -> True

# And when looking for subsrings
any(i in '<string>' for i in ('11','22','33'))
# any(i in 'hello' for i in ('18','36','613')) -> False
# any(i in '613 mitzvahs' for i in ('18','36','613')) ->True

shape is a property of both numpy ndarray's and matrices.

A.shape

will return a tuple (m, n), where m is the number of rows, and n is the number of columns.

In fact, the numpy matrix object is built on top of the ndarray object, one of numpy's two fundamental objects (along with a universal function object), so it inherits from ndarray

I'm using this function

function isNull() {
    for (var i = 0; i < arguments.length; i++) {
        if (
            typeof arguments[i] !== 'undefined'
            && arguments[i] !== undefined
            && arguments[i] != null
            && arguments[i] != NaN
            && arguments[i] 
        ) return arguments[i];
      }
}

test

console.log(isNull(null, null, undefined, 'Target'));

As mentioned in previous answers, both serve almost same purpose. Personally I like git rebase and merge request (as in gitlab). It takes burden off of the reviewer/maintainer, making sure that while adding merge request, the feature branch includes all of the latest commits done on main branch after feature branch is created. Here is a very useful article explaining rebase in detail: https://git-scm.com/book/en/v2/Git-Branching-Rebasing

The function match works on vectors:

x <- sample(1:10)
x
# [1]  4  5  9  3  8  1  6 10  7  2
match(c(4,8),x)
# [1] 1 5

match only returns the first encounter of a match, as you requested. It returns the position in the second argument of the values in the first argument.

For multiple matching, %in% is the way to go:

x <- sample(1:4,10,replace=TRUE)
x
# [1] 3 4 3 3 2 3 1 1 2 2
which(x %in% c(2,4))
# [1]  2  5  9 10

%in% returns a logical vector as long as the first argument, with a TRUE if that value can be found in the second argument and a FALSE otherwise.

JConsole has a graphical view.

You also have VisualVM and Oracle JRockit Mission Control

There is no way to do pure text search in whole work workspace/project via a shortcut that I know of (and it is a PITA), but this will find references in the workspace:

1. Put your cursor on what you want to lookup
2. Press Ctrl + Shift + g

this is not your answer but is for those come here searching solution for another problem. I wanted to get sum of a column of related table conditionally. In my database Deals has many Activities I wanted to get the sum of the "amount_total" from Activities table where activities.deal_id = deal.id and activities.status = paid so i did this.

$query->withCount([
'activity AS paid_sum' => function ($query) {
            $query->select(DB::raw("SUM(amount_total) as paidsum"))->where('status', 'paid');
        }
    ]);

it returns

"paid_sum_count" => "320.00"

in Deals attribute.

This it now the sum which i wanted to get not the count.

I ran into the same error, but I was not using model-first. It turned out that somehow my EDMX file contained a reference to a table even though it did not show up in the designer. Interestingly, when I did a text search for the table name in Visual Studio (2013) the table was not found.

To solve the issue, I used an external editor (Notepad++) to find the reference to the offending table in the EDMX file, and then (carefully) removed all references to the table. I am sorry to say that I do not know how the EDMX file got into this state in the first place.

you can create array follow the code below:

var arraymultidimensional = []
    arraymultidimensional = [[value1,value2],[value3,value4],[value5,value6]];

Result:
[v1][v2] position 0
[v3][v4] position 1
[v5][v6] position 2

For add to array dinamically, use the method below:

//vectorvalue format = "[value,value,...]"
function addToArray(vectorvalue){
  arraymultidimensional[arraymultidimensional.length] = vectorvalue;
}

Hope this helps. :)

[MySQL]

In these (very rare) cases:

• two tables that really need different collation types

• values not coming from a table, but from an explicit enumeration, for instance:

  SELECT 1 AS numbers UNION ALL SELECT 2 UNION ALL SELECT 3

you can compare the values between the different tables by using CAST or CONVERT:

CAST('my text' AS CHAR CHARACTER SET utf8)

CONVERT('my text' USING utf8)

See CONVERT and CAST documentation on MySQL website.

No you can't overload it; a static constructor is useful for initializing any static fields associated with a type (or any other per-type operations) - useful in particular for reading required configuration data into readonly fields, etc.

It is run automatically by the runtime the first time it is needed (the exact rules there are complicated (see "beforefieldinit"), and changed subtly between CLR2 and CLR4). Unless you abuse reflection, it is guaranteed to run at most once (even if two threads arrive at the same time).

del statement does not delete an instance, it merely deletes a name.

When you do del i, you are deleting just the name i - but the instance is still bound to some other name, so it won't be Garbage-Collected.

If you want to release memory, your dataframes has to be Garbage-Collected, i.e. delete all references to them.

If you created your dateframes dynamically to list, then removing that list will trigger Garbage Collection.

>>> lst = [pd.DataFrame(), pd.DataFrame(), pd.DataFrame()]
>>> del lst     # memory is released

If you created some variables, you have to delete them all.

>>> a, b, c = pd.DataFrame(), pd.DataFrame(), pd.DataFrame()
>>> lst = [a, b, c]
>>> del a, b, c # dfs still in list
>>> del lst     # memory release now

Maybe the uuid module?

Well if you know the basics behind them, it shouldn't be too hard.

Generally you create an array called "buckets" that contain the key and value, with an optional pointer to create a linked list.

When you access the hash table with a key, you process the key with a custom hash function which will return an integer. You then take the modulus of the result and that is the location of your array index or "bucket". Then you check the unhashed key with the stored key, and if it matches, then you found the right place.

Otherwise, you've had a "collision" and must crawl through the linked list and compare keys until you match. (note some implementations use a binary tree instead of linked list for collisions).

Check out this fast hash table implementation:

https://attractivechaos.wordpress.com/2009/09/29/khash-h/

The hex codec has been chucked in 3.x. Use binascii instead:

>>> binascii.hexlify(b'hello')
b'68656c6c6f'

try something using a for loop

 for i in `egrep -lR "YOURSEARCH" .` ; do echo  $i; sed 's/f/k/' <$i >/tmp/`basename $i`; mv /tmp/`basename $i` $i; done

not pretty, but should do.

As an alternate option, if you have the Sqlite Database Browser and are more inclined to a GUI solution, you can edit the sqlite_sequence table where field name is the name of your table. Double click the cell for the field seq and change the value to 0 in the dialogue box that pops up.

import csv, sqlite3

def _get_col_datatypes(fin):
    dr = csv.DictReader(fin) # comma is default delimiter
    fieldTypes = {}
    for entry in dr:
        feildslLeft = [f for f in dr.fieldnames if f not in fieldTypes.keys()]        
        if not feildslLeft: break # We're done
        for field in feildslLeft:
            data = entry[field]

        # Need data to decide
        if len(data) == 0:
            continue

        if data.isdigit():
            fieldTypes[field] = "INTEGER"
        else:
            fieldTypes[field] = "TEXT"
    # TODO: Currently there's no support for DATE in sqllite

if len(feildslLeft) > 0:
    raise Exception("Failed to find all the columns data types - Maybe some are empty?")

return fieldTypes


def escapingGenerator(f):
    for line in f:
        yield line.encode("ascii", "xmlcharrefreplace").decode("ascii")


def csvToDb(csvFile,dbFile,tablename, outputToFile = False):

    # TODO: implement output to file

    with open(csvFile,mode='r', encoding="ISO-8859-1") as fin:
        dt = _get_col_datatypes(fin)

        fin.seek(0)

        reader = csv.DictReader(fin)

        # Keep the order of the columns name just as in the CSV
        fields = reader.fieldnames
        cols = []

        # Set field and type
        for f in fields:
            cols.append("\"%s\" %s" % (f, dt[f]))

        # Generate create table statement:
        stmt = "create table if not exists \"" + tablename + "\" (%s)" % ",".join(cols)
        print(stmt)
        con = sqlite3.connect(dbFile)
        cur = con.cursor()
        cur.execute(stmt)

        fin.seek(0)


        reader = csv.reader(escapingGenerator(fin))

        # Generate insert statement:
        stmt = "INSERT INTO \"" + tablename + "\" VALUES(%s);" % ','.join('?' * len(cols))

        cur.executemany(stmt, reader)
        con.commit()
        con.close()

If you want be sure you need to check both

SomeProperty == null || SomeProperty == Guid.Empty

Because it can be null 'Nullable' and it can be an empty GUID something like this {00000000-0000-0000-0000-000000000000}

Scala function :

def countChange(money: Int, coins: List[Int]): Int = {

def loop(money: Int, lcoins: List[Int], count: Int): Int = {
  // if there are no more coins or if we run out of money ... return 0 
  if ( lcoins.isEmpty || money < 0) 0
  else{
    if (money == 0 ) count + 1   
/* if the recursive subtraction leads to 0 money left - a prefect division hence return count +1 */
    else
/* keep iterating ... sum over money and the rest of the coins and money - the first item and the full set of coins left*/
      loop(money, lcoins.tail,count) + loop(money - lcoins.head,lcoins, count)
  }
}

val x = loop(money, coins, 0)
Console println x
x
}

This is good for shallow cloning. The object spread is a standard part of ECMAScript 2018.

For deep cloning you'll need a different solution.

const clone = {...original} to shallow clone

const newobj = {...original, prop: newOne} to immutably add another prop to the original and store as a new object.

Hello There is an example:

import numpy as np
import matplotlib.pyplot as ptl

def grafica_seno_coseno():
    x = np.arange(-4,2*np.pi, 0.3)
    y = 2*np.sin(x)
    y2 = 3*np.cos(x)
    ptl.plot(x, y,  '-gD')
    ptl.plot(x, y2, '-rD')
    for xitem,yitem in np.nditer([x,y]):
        etiqueta = "{:.1f}".format(xitem)
        ptl.annotate(etiqueta, (xitem,yitem), textcoords="offset points",xytext=(0,10),ha="center")
    for xitem,y2item in np.nditer([x,y2]):
        etiqueta2 = "{:.1f}".format(xitem)
        ptl.annotate(etiqueta2, (xitem,y2item), textcoords="offset points",xytext=(0,10),ha="center")
    ptl.grid(True)
    return ptl.show()

Try this:

Import-Module Webadministration
Get-ChildItem -Path IIS:\Sites

It should return something that looks like this:

Name             ID   State      Physical Path                  Bindings
----             --   -----      -------------                  --------
ChristophersWeb 22   Started    C:\temp             http *:8080:ChristophersWebsite.ChDom.com

From here you can refine results, but be careful. A pipe to the select statement will not give you what you need. Based on your requirements I would build a custom object or hashtable.

A note for using Docker Windows containers after I had to look for this problem for a long time!

Condiditions:

• Windows 10
• Docker Desktop (latest version)
• using Docker Windows Container for image microsoft/mssql-server-windows-developer

Problem:

• I wanted to mount a host dictionary into my windows container.

Solution as partially discripted here:

• create docker container

docker run -d -p 1433:1433 -e sa_password=<STRONG_PASSWORD> -e ACCEPT_EULA=Y microsoft/mssql-server-windows-developer

• go to command shell in container

docker exec -it <CONTAINERID> cmd.exe

• create DIR

mkdir DirForMount

• stop container

docker container stop <CONTAINERID>

• commit container

docker commit <CONTAINERID> <NEWIMAGENAME>

• delete old container

docker container rm <CONTAINERID>

• create new container with new image and volume mounting

docker run -d -p 1433:1433 -e sa_password=<STRONG_PASSWORD> -e ACCEPT_EULA=Y -v C:\DirToMount:C:\DirForMount <NEWIMAGENAME>

After this i solved this problem on docker windows containers.

The language version is chosen based on the project's target framework by default.

Each project may use a different version of .Net framework, the best suitable C# compiler will be chosen by default by looking at the target framework. From visual studio, UI will not allow the users to changes the language version, however, we can change the language version by editing the project file with addition of new property group. But this may cause compile/run time issues in existing code.

<PropertyGroup>  
<LangVersion>8.0</LangVersion>  
</PropertyGroup>

I could see the following from Microsoft docs.

The compiler determines a default based on these rules:

Target framework  version     C# language version default
.NET Core           3.x         C# 8.0
.NET Core           2.x         C# 7.3
.NET Standard       2.1         C# 8.0
.NET Standard       2.0         C# 7.3
.NET Standard       1.x         C# 7.3
.NET Framework      all         C# 7.3

You can disable FK and CHECK constraints only in SQL 2005+. See ALTER TABLE

ALTER TABLE foo NOCHECK CONSTRAINT ALL

or

ALTER TABLE foo NOCHECK CONSTRAINT CK_foo_column

Primary keys and unique constraints can not be disabled, but this should be OK if I've understood you correctly.

As ultimately suggested by this other answer and it's comments on this page:

error: function(xhr, status, error) {
  var err = JSON.parse(xhr.responseText);
  alert(err.Message);
}

This directive will instantly focus and select any text in the element as soon as it's displayed. This might require a setTimeout for some cases, it has not been tested much.

import { Directive, ElementRef, OnInit } from '@angular/core';

@Directive({
  selector: '[appPrefixFocusAndSelect]',
})
export class FocusOnShowDirective implements OnInit {

  constructor(private el: ElementRef) {
    if (!el.nativeElement['focus']) {
      throw new Error('Element does not accept focus.');
    }
  }

  ngOnInit(): void {
    const input: HTMLInputElement = this.el.nativeElement as HTMLInputElement;
    input.focus();
    input.select();
  }
}

And in the HTML:

 <mat-form-field>
     <input matInput type="text" appPrefixFocusAndSelect [value]="'etc'">
 </mat-form-field>

In case you are using IntelliJ you can enable the Database view (View -> Tools Window -> Database)

Inside that view connect to your database. Then you can rightclick the database and select "Copy DDL". Other IDEs may offer a similar function.

For people that have PowerShell 3 or later (i.e. Windows Server 2012+ or Windows Server 2008 R2 with the Windows Management Framework 4.0 update), you can do this one-liner instead of invoking System.Net.WebRequest:

$statusCode = wget http://stackoverflow.com/questions/20259251/ | % {$_.StatusCode}

There is a command

svn revert -R .

OR
you can use the --depth=infinity, which is actually same as above:

svn revert --depth=infinity 

svn revert is inherently dangerous, since its entire purpose is to throw away data—namely, your uncommitted changes. Once you've reverted, Subversion provides no way to get back those uncommitted changes

If the <i> tag isn't displayed as a block and causing the probelm then this should work:

<td style="white-space:nowrap;"><i class="flag-bfh-ES"></i>&nbsp;+34&nbsp;666&nbsp;66&nbsp;66&nbsp;66</td>

My solution is to check the version number of pip and use the import the correct main function correctly

    import pip

    if int(pip.__version__.split('.')[0])>9:
        from pip._internal import main
    else:
        from pip import main
    def install(package):
        main(['install', package])

In my case, I had a page where it was an input type='date' whose reference I had got on page load, but When I tried to interact with it, it showed this exception and that was quite meaningful as Javascript had manipulated my control hence it was detached from the document and I had to re-get its reference after the javascript had performed its job with the control. So, this is how my code looked before the exception:

if (elemDate != null)
{ 
    elemDate.Clear(); 
    elemDate.SendKeys(model.Age);
}

Code after the exception was raised:

int tries = 0;
do
{
    try
    {
        tries++;
        if (elemDate != null)
        {
            // these lines were causing the exception so I had break after these are successfully executed because if they are executed that means the control was found and attached to the document and we have taken the reference of it again.
            elemDate.Clear();
            elemDate.SendKeys(model.Age);
            break;
        }
    }
    catch (StaleElementReferenceException)
    {
        System.Threading.Thread.Sleep(10); // put minor fake delay so Javascript on page does its actions with controls
        elemDate = driver.FindElement(By.Id(dateId));
    }
} while (tries < 3); // Try it three times.

So, Now you can perform further actions with your code or you can quit the driver if it was unsuccessful in getting the control to work.

if(tries > 2)
{
   // element was not found, find out what is causing the control detachment.
   // driver.Quit();
   return;
}

// Hurray!! Control was attached and actions were performed.
// Do something with it...

Something that I have learnt so far is, catching exceptions to know about successful code execution is not a good idea, But, I had to do it and I found this work-around to be working well in this case.

PS: After writing all this, I just noticed the tags that this thread was for java. This code sample is just for demonstration purpose, It might help people who have issue in C# language. Or it can be easily translated to java as it doesn't have much C# specific code.

Convert the string to a decimal then divide it by 100 and apply the currency format string:

string.Format("{0:#.00}", Convert.ToDecimal(myMoneyString) / 100);

Edited to remove currency symbol as requested and convert to decimal instead.

This is the only solution that worked for me on Ubuntu-18.

Inside the file app.py , use:

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=80)

The code above will give the same permission error unless sudo is used to run it:

sudo python3 app.py

If you came here from Google, trying to find where your previously created virtualenv installation ended up, and why there is no command to find it, here's the low-down.

The design of virtualenv has a fundamental flaw of not being able to keep track of it's own created environments. Someone was not quite in their right mind when they created virtualenv without having a rudimentary way to keep track of already created environments, and certainly not fit for a time and age when most pip requirements require multi-giga-byte installations, which should certainly not go into some obscure .virtualenvs sub-directory of your ~/home.

IMO, the created virtualenv directory should be created in $CWD and a file called ~/.virtualenv (in home) should keep track of the name and path of that creation. Which is a darn good reason to use Conda/Miniconda3 instead, which does seem to keep good track of this.

As answered here, the only way to keep track of this, is to install yet another package called virtualenvwrapper. If you don't do that, you will have to search for the created directory by yourself. Clearly, if you don't remember the name or the location it was created with/at, you will most likely never find your virtual environment again...

One try to remedy the situation in windows, is by putting the following functions into your powershell profile:

# wrap virtualenv.exe and write last argument (presumably 
# your virtualenv name) to the file: $HOME/.virtualenv.
function ven { if( $args.count -eq 0) {Get-Content ~/.virtualenv } else {virtualenv.exe "$args"; Write-Output ("{0} `t{1}" -f $args[-1],$PWD) | Out-File -Append $HOME/.virtualenv }}

# List what's in the file or the directories under ~/.virtualenvs
function lsven { try {Get-Content ~/.virtualenv } catch {Get-ChildItem ~\.virtualenvs -Directory | Select-Object -Property Name } }

_{WARNING: This will write to ~\.virtualenv...}

I've used the implementation above and just now I came to know that it doesn't work on iPad running iOS 13. I had to add these lines before present() call in order to make it work

//avoiding to crash on iPad
if let popoverController = activityViewController.popoverPresentationController {
     popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
     popoverController.sourceView = self.view
     popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
}

That's how it works for me

func shareData(_ dataToShare: [Any]){

        let activityViewController = UIActivityViewController(activityItems: dataToShare, applicationActivities: nil)

        //exclude some activity types from the list (optional)
        //activityViewController.excludedActivityTypes = [
            //UIActivity.ActivityType.postToFacebook
        //]

        //avoiding to crash on iPad
        if let popoverController = activityViewController.popoverPresentationController {
            popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
            popoverController.sourceView = self.view
            popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
        }

        self.present(activityViewController, animated: true, completion: nil)
    }

    string target= "http://www.google.com";
try
{
    System.Diagnostics.Process.Start(target);
}
catch (System.ComponentModel.Win32Exception noBrowser)
{
    if (noBrowser.ErrorCode==-2147467259)
    MessageBox.Show(noBrowser.Message);
}
catch (System.Exception other)
{
    MessageBox.Show(other.Message);
}

you can add some javascript to surpress those obnoxious validation bubbles and add your own validators.

document.addEventListener('invalid', (function(){
    return function(e) {
      //prevent the browser from showing default error bubble / hint
      e.preventDefault();
      // optionally fire off some custom validation handler
      // myValidation();
    };
})(), true);

The easy way is to define a non-ASCII character... as a character that is not an ASCII character.

LC_ALL=C grep '[^ -~]' file.xml

Add a tab after the ^ if necessary.

Setting LC_COLLATE=C avoids nasty surprises about the meaning of character ranges in many locales. Setting LC_CTYPE=C is necessary to match single-byte characters — otherwise the command would miss invalid byte sequences in the current encoding. Setting LC_ALL=C avoids locale-dependent effects altogether.

Use pyplot.text() (import matplotlib.pyplot as plt)

import matplotlib.pyplot as plt

x=[1,2,3]
y=[9,8,7]

plt.plot(x,y)
for a,b in zip(x, y): 
    plt.text(a, b, str(b))
plt.show()

I'm not sure what the problem is; running the below works as expected:

<div id="thumb0" class="thumbs" onclick="klikaj('rad1')">knock knock</div>
?<div id="rad1" style="visibility: hidden">hello world</div>????????????????????????????????
<script>
function klikaj(i) {
    document.getElementById(i).style.visibility='visible';
}
</script>

I understand you intention well, I use buffers exclusively too, and occasionally do split if needed.

below is excerpt of my .vimrc

" disable macro, since not used in 90+% use cases
map q <Nop>
" q,  close/hide current window, or quit vim if no other window
nnoremap q :if winnr('$') > 1 \|hide\|else\|silent! exec 'q'\|endif<CR>
" qo, close all other window    -- 'o' stands for 'only'
nnoremap qo :only<CR>
set hidden
set timeout
set timeoutlen=200   " let vim wait less for your typing!

Which fits my workflow quite well

If q was pressed

• hide current window if multiple window open, else try to quit vim.

if qo was pressed,

• close all other window, no effect if only one window.

Of course, you can wrap that messy part into a function, eg

func! Hide_cur_window_or_quit_vim()
    if winnr('$') > 1
        hide
    else
        silent! exec 'q'
    endif
endfunc
nnoremap q :call Hide_cur_window_or_quit_vim()<CR>

Sidenote: I remap q, since I do not use macro for editing, instead use :s, :g, :v, and external text processing command if needed, eg, :'{,'}!awk 'some_programm', or use :norm! normal-command-here.

Change display:inline to display:inline-block

.test {
  width:200px;
  display:inline-block;
  overflow: auto;
  white-space: nowrap;
  margin:0px auto;
  border:1px red solid;
}

I prefer to use

pushd d:\windows\movie

because it requires no switches yet the working directory will change to the correct drive and path in one step.

Added plus:

• also works with UNC paths if an unused drive letter is available for automatic drive mapping,
• easy to go back to the previous working directory: just enter popd.

To check if something exits, you can use the PHP function isset() see php.net. This function will check if the variable is set and is not NULL.

Example:

if(isset($obj->a))
{ 
  //do something
}

If you need to check if a property exists in a class, then you can use the build in function property_exists()

Example:

if (property_exists('class', $property)) {
    //do something
}

Hope this will help somebody to develop custom checkbox component with custom styles. This solution can use with forms too.

Usage

Outside forms

<app-checkbox [label]="'Example'" [isChecked]="true"></app-checkbox>

Inside forms

<app-checkbox [label]="'Type 0'" formControlName="Type1"></app-checkbox>

What you're using is called the haversine formula, which calculates the distance between two points on a sphere as the crow flies. The Google Maps link you provided shows the distance as 2.2 km because it's not a straight line.

Wolphram Alpha is a great resource for doing geographic calculations, and also shows a distance of 1.652 km between these two points.

If you're looking for straight-line distance (as the crow files), your function is working correctly. If what you want is driving distance (or biking distance or public transportation distance or walking distance), you'll have to use a mapping API (Google or Bing being the most popular) to get the appropriate route, which will include the distance.

Incidentally, the Google Maps API provides a packaged method for spherical distance, in its google.maps.geometry.spherical namespace (look for computeDistanceBetween). It's probably better than rolling your own (for starters, it uses a more precise value for the Earth's radius).

For the picky among us, when I say "straight-line distance", I'm referring to a "straight line on a sphere", which is actually a curved line (i.e. the great-circle distance), of course.

If you have date object like

var date = new Date('2017/12/03');

then there is inbuilt method in javascript for getting date in milliseconds format which is valueOf()

date.valueOf(); //1512239400000 in milliseconds format

use zip

columns = zip(*rows) #transpose rows to columns
print columns[0] #print the first column
#you can also do more with the columns
print columns[1] # or print the second column
columns.append([7,7,7]) #add a new column to the end
backToRows = zip(*columns) # now we are back to rows with a new column
print backToRows

you can also use numpy

a = numpy.array(a)
print a[:,0]

Edit: zip object is not subscriptable. It need to be converted to list to access as list:

column = list(zip(*row))

You need to url-escape the ampersand. Use:

var wysiwyg_clean = wysiwyg.replace('&', '%26');

As Wolfram points out, this is nicely handled (along with all the other special characters) by encodeURIComponent.

COPY your table (Name, Latitude, Longitude) FROM 'C:\Temp\your file.csv' DELIMITERS ',' CSV HEADER;

Use c:\Temp\"Your File"\.

If a constant is needed in more than one class, I put it in config/initializers/contant.rb always in all caps (list of states below is truncated).

STATES = ['AK', 'AL', ... 'WI', 'WV', 'WY']

They are available through out the application except in model code as such:

    <%= form.label :states, %>
    <%= form.select :states, STATES, {} %>

To use the constant in a model, use attr_accessor to make the constant available.

class Customer < ActiveRecord::Base
    attr_accessor :STATES

    validates :state, inclusion: {in: STATES, message: "-- choose a State from the drop down list."}
end

change your code to:

function ChangePurpose(Vid, PurId) {
    var Success = false;
    $.ajax({
        type: "POST",
        url: "CHService.asmx/SavePurpose",
        dataType: "text",
        async: false,
        data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            Success = true;
        },
        error: function (textStatus, errorThrown) {
            Success = false;
        }
    });
    //done after here
    return Success;
} 

You can only return the values from a synchronous function. Otherwise you will have to make a callback.

So I just added async:false, to your ajax call

Update:

jquery ajax calls are asynchronous by default. So success & error functions will be called when the ajax load is complete. But your return statement will be executed just after the ajax call is started.

A better approach will be:

     // callbackfn is the pointer to any function that needs to be called
     function ChangePurpose(Vid, PurId, callbackfn) {
        var Success = false;
        $.ajax({
            type: "POST",
            url: "CHService.asmx/SavePurpose",
            dataType: "text",
            data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
            contentType: "application/json; charset=utf-8",
            success: function (data) {
                callbackfn(data)
            },
            error: function (textStatus, errorThrown) {
                callbackfn("Error getting the data")
            }
        });
     } 

     function Callback(data)
     {
        alert(data);
     }

and call the ajax as:

 // Callback is the callback-function that needs to be called when asynchronous call is complete
 ChangePurpose(Vid, PurId, Callback);

In addition to the orbeckst answer one might also want to shift the subplots down. Here's an MWE in OOP style:

import matplotlib.pyplot as plt

fig = plt.figure()
st = fig.suptitle("suptitle", fontsize="x-large")

ax1 = fig.add_subplot(311)
ax1.plot([1,2,3])
ax1.set_title("ax1")

ax2 = fig.add_subplot(312)
ax2.plot([1,2,3])
ax2.set_title("ax2")

ax3 = fig.add_subplot(313)
ax3.plot([1,2,3])
ax3.set_title("ax3")

fig.tight_layout()

# shift subplots down:
st.set_y(0.95)
fig.subplots_adjust(top=0.85)

fig.savefig("test.png")

gives:

No, there isn't such constant.

If you need only Parameter info then:

On Mac, it's assigned to Command+P

On Windows, it's assigned to Ctrl+P

If you need document info then:

On Mac, it's assigned to Command+Q

On Windows, it's assigned to Ctrl+Q

Probably the best course of action is "do it as std lib does it". That is: All inline, all in headers.

// in the header
namespase my_namespace {

   class my_standard_named_class final {
public:
         static void standard_declared_defined_method () {
            // even the comment is standard
         }
   } ;

} // namespase my_namespace 

As simple as that ...

I like a generated class comment like this:

/**
 * I... 
 * 
 * $Id$
 */

The "I..." immediately encourages the developer to describe what the class does. I does seem to improve the problem of undocumented classes.

And of course the $Id$ is a useful CVS keyword.

You can specify both max post size and max file size limit in php.ini

post_max_size = 64M
upload_max_filesize = 64M

You need to set a layout manager for the JFrame to use - This deals with how components are positioned. A useful one is the BorderLayout manager.

Simply adding the following line of code should fix your problems:

mainFrame.setLayout(new BorderLayout());

(Do this before adding components to the JFrame)

Here is another option in Chrome.

Hit F12 to open developer tools. Then Resources > Cache Storage > Refresh Caches.

I like this option because I don't have to disable cache as in other answers.

Well, what about something like this:

PS3="Select database or <Q> to quit: "
select DB in db1 db2 db3; do
   [ "${REPLY^*}" = 'Q' ] && break
   echo "Should backup $DB..."
done

>>> s1 ='arbit'
>>> s2 = 'hello world '.join( [s]*3 )
>>> print s2
arbit hello world arbit hello world arbit

The problem you're having is that the event-handlers are being bound before the elements are present in the DOM, if you wrap the jQuery inside of a $(document).ready() then it should work perfectly well:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").show("slow");
        });

    });

An alternative is to place the <script></script> at the foot of the page, so it's encountered after the DOM has been loaded and ready.

To make the div hide again, once the #music element is clicked, simply use toggle():

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").toggle();
        });
    });

JS Fiddle demo.

And for fading:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").fadeToggle();
        });
    });

In Android Studio, open the Device Manager: Tools -> Android -> Android Device Monitor

In Eclipse open the Device Manager:

In the device manager you can add files to the SD Card here:

>>> a=$("#communitymode")[0]
<input id="communitymode" type="checkbox" name="communitymode">
>>> a.type
"checkbox"

Or, more of the style of jQuery:

$("#myinput").attr('type') == 'checkbox'

use .NET3.5 it worked for me for similar issue.

Using Ubuntu 12.04 it appears to work fine for me:

What error are you getting exactly? - double check you've spelt psycopg right - that's quite often a gotcha... and it never hurts to run an apt-get update to make sure your repo. is up to date.

I know this is an old question but just for the record this can also be done by passing appropriate connection options as arguments to the _mysql.connect call. For example,

con = _mysql.connect(host='localhost', user='dell-pc', passwd='', db='test',
          connect_timeout=1000)

Notice the use of keyword parameters (host, passwd, etc.). They improve the readability of your code.

For detail about different arguments that you can pass to _mysql.connect, see MySQLdb API documentation

The difference between commit() and apply()

We might be confused by those two terms, when we are using SharedPreference. Basically they are probably the same, so let’s clarify the differences of commit() and apply().

1.Return value:

apply() commits without returning a boolean indicating success or failure. commit() returns true if the save works, false otherwise.

2. Speed:

apply() is faster. commit() is slower.

3. Asynchronous v.s. Synchronous:

apply(): Asynchronous commit(): Synchronous

4. Atomic:

apply(): atomic commit(): atomic

5. Error notification:

apply(): No commit(): Yes

1. Create a class

public class Test {

 public static void main(String[] args) {
    // TODO Auto-generated method stub
     String s[] = {"app","amm","abb","akk","all"};
     doForAllTabs(s);

 }
 public static void doForAllTabs(String[] tablist){
     for(int i = 0; i<tablist.length;i++){
         System.out.println(tablist[i]);
    }
  }
}

2. Right click on left side of System.out.println(tablist[i]); in Eclipse --> select Toggle Breakpoint

3. Right click on toggle point --> select Breakpoint properties

4. Check the Conditional Check Box --> write tablist[i].equalsIgnoreCase("amm") in text field --> Click on OK

5. Right click on class --> Debug As --> Java Application

You could use the ViewCommand design pattern. It describes a method for the MVVM design pattern to control a View from a ViewModel with commands.

I've implemented it based on King A.Majid's suggestion to use the MVVM Light Messenger class. The ViewCommandManager class handles invoking commands in connected views. It's basically the other direction of regular Commands, for these cases when a ViewModel needs to do some action in its View. It uses reflection like data-bound commands and WeakReferences to avoid memory leaks.

There is a hacky way to do it.

Set some boolean field to indicate whether the work was completed. Then before the block of code, set a timer to run a piece of code after your timeout. The timer will check if the block of code had finished executing, and if not, throw an exception. Otherwise it will do nothing.

The end of the block of code should, of course, set the field to true to indicate the work was done.

That error is here to force you to write better code, and be sure to use everything you declare or import. It makes it easier to read code written by other people (you are always sure that all declared variables will be used), and avoid some possible dead code.

But, if you really want to skip this error, you can use the blank identifier (_) :

package main

import (
    "fmt" // imported and not used: "fmt"
)

func main() {
    i := 1 // i declared and not used
}

becomes

package main

import (
    _ "fmt" // no more error
)

func main() {
    i := 1 // no more error
    _ = i
}

As said by kostix in the comments below, you can find the official position of the Go team in the FAQ:

The presence of an unused variable may indicate a bug, while unused imports just slow down compilation. Accumulate enough unused imports in your code tree and things can get very slow. For these reasons, Go allows neither.

If you have directories containing really (>100'000) many files, here is a (non-portable) way to go:

String directoryPath = "a path";

// -f flag is important, because this way ls does not sort it output,
// which is way faster
String[] params = { "/bin/sh", "-c",
    "ls -f " + directoryPath + " | wc -l" };
Process process = Runtime.getRuntime().exec(params);
BufferedReader reader = new BufferedReader(new InputStreamReader(
    process.getInputStream()));
String fileCount = reader.readLine().trim() - 2; // accounting for .. and .
reader.close();
System.out.println(fileCount);

For iPhone 5.5" display you need to change the simulator to "Physical Size" on iPhone 8 Plus

as explained here

With help from numpy one can calculate for example a linear fitting.

# plot the data itself
pylab.plot(x,y,'o')

# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

Which model is the "best fitting model" depends on what you mean by "best". R has tools to help, but you need to provide the definition for "best" to choose between them. Consider the following example data and code:

x <- 1:10
y <- x + c(-0.5,0.5)

plot(x,y, xlim=c(0,11), ylim=c(-1,12))

fit1 <- lm( y~offset(x) -1 )
fit2 <- lm( y~x )
fit3 <- lm( y~poly(x,3) )
fit4 <- lm( y~poly(x,9) )
library(splines)
fit5 <- lm( y~ns(x, 3) )
fit6 <- lm( y~ns(x, 9) )

fit7 <- lm( y ~ x + cos(x*pi) )

xx <- seq(0,11, length.out=250)
lines(xx, predict(fit1, data.frame(x=xx)), col='blue')
lines(xx, predict(fit2, data.frame(x=xx)), col='green')
lines(xx, predict(fit3, data.frame(x=xx)), col='red')
lines(xx, predict(fit4, data.frame(x=xx)), col='purple')
lines(xx, predict(fit5, data.frame(x=xx)), col='orange')
lines(xx, predict(fit6, data.frame(x=xx)), col='grey')
lines(xx, predict(fit7, data.frame(x=xx)), col='black')

Which of those models is the best? arguments could be made for any of them (but I for one would not want to use the purple one for interpolation).

For the recent version of MySQL,

default-character-set = utf8

causes a problem. It's deprecated I think.

As Justin Ball says in "Upgrade to MySQL 5.5.12 and now MySQL won’t start, you should:

1. Remove that directive and you should be good.

2. Then your configuration file ('/etc/my.cnf' for example) should look like that:

   [mysqld]
   collation-server = utf8_unicode_ci
   init-connect='SET NAMES utf8'
   character-set-server = utf8
   

3. Restart MySQL.

4. For making sure, your MySQL is UTF-8, run the following queries in your MySQL prompt:

   • First query:

      mysql> show variables like 'char%';
     

     The output should look like:

      +--------------------------+---------------------------------+
      | Variable_name            | Value                           |
      +--------------------------+---------------------------------+
      | character_set_client     | utf8                            |
      | character_set_connection | utf8                            |
      | character_set_database   | utf8                            |
      | character_set_filesystem | binary                          |
      | character_set_results    | utf8                            |
      | character_set_server     | utf8                            |
      | character_set_system     | utf8                            |
      | character_sets_dir       | /usr/local/mysql/share/charsets/|
      +--------------------------+---------------------------------+
     

   • Second query:

      mysql> show variables like 'collation%';
     

     And the query output is:

      +----------------------+-----------------+
      | Variable_name        | Value           |
      +----------------------+-----------------+
      | collation_connection | utf8_general_ci |
      | collation_database   | utf8_unicode_ci |
      | collation_server     | utf8_unicode_ci |
      +----------------------+-----------------+
     

You can do this by using /parent::node() in the xpath. Simply append /parent::node() to the child elements xpath.

For example: Let xpath of child element is childElementXpath.

Then xpath of its immediate ancestor would be childElementXpath/parent::node().

Xpath of its next ancestor would be childElementXpath/parent::node()/parent::node()

and so on..

Also, you can navigate to an ancestor of an element using 'childElementXpath/ancestor::*[@attr="attr_value"]'. This would be useful when you have a known child element which is unique but has a parent element which cannot be uniquely identified.

On OSX, the command will depend on the flavour of python installation you have.

Python 2.x - Default

sudo pip install requests

Python 3.x

sudo pip3 install requests

You have probably added them to the repository before putting *.pyc in .gitignore.
First remove them from the repository.

What about using MAX? That way if no data is found the variable is set to NULL, otherwise the maximum value.
Since you expect either 0 or 1 value, MAX should be OK to use.

v_column my_table.column%TYPE;
select MAX(column) into v_column from my_table where ...;

Note: The placement of cross_origin should be right and dependencies are installed. On the client side, ensure to specify kind of data server is consuming. For example application/json or text/html

For me the code written below did magic

from flask import Flask,request,jsonify
from flask_cors import CORS,cross_origin
app=Flask(__name__)
CORS(app, support_credentials=True)
@app.route('/api/test', methods=['POST', 'GET','OPTIONS'])
@cross_origin(supports_credentials=True)
def index():
    if(request.method=='POST'):
     some_json=request.get_json()
     return jsonify({"key":some_json})
    else:
        return jsonify({"GET":"GET"})


if __name__=="__main__":
    app.run(host='0.0.0.0', port=5000)

1. Your request should be to the server, NOT the server.js file which instantiates it. So, the request should look something like this: xmlhttp.open("GET","http://localhost:8001/", true); Also, you are trying to serve the front-end (index.html) AND serve AJAX requests at the same URI. To accomplish this, you are going to have to introduce logic to your server.js that will differentiate between your AJAX requests and a normal http access request. To do this, you'll want to either introduce GET/POST data (i.e. call http://localhost:8001/?getstring=true) or use a different path for your AJAX requests (i.e. call http://localhost:8001/getstring). On the server end then, you'll need to examine the request object to determine what to write on the response. For the latter option, you need to use the 'url' module to parse the request.

2. You are correctly calling listen() but incorrectly writing the response. First of all, if you wish to serve index.html when navigating to http://localhost:8001/, you need to write the contents of the file to the response using response.write() or response.end(). First, you need to include fs=require('fs') to get access to the filesystem. Then, you need to actually serve the file.

3. XMLHttpRequest needs a callback function specified if you use it asynchronously (third parameter = true, as you have done) AND want to do something with the response. The way you have it now, string will be undefined (or perhaps null), because that line will execute before the AJAX request is complete (i.e. the responseText is still empty). If you use it synchronously (third parameter = false), you can write inline code as you have done. This is not recommended as it locks the browser during the request. Asynchronous operation is usually used with the onreadystatechange function, which can handle the response once it is complete. You need to learn the basics of XMLHttpRequest. Start here.

Here is a simple implementation that incorporates all of the above:

server.js:

var http = require('http'),
      fs = require('fs'),
     url = require('url'),
 choices = ["hello world", "goodbye world"];

http.createServer(function(request, response){
    var path = url.parse(request.url).pathname;
    if(path=="/getstring"){
        console.log("request recieved");
        var string = choices[Math.floor(Math.random()*choices.length)];
        console.log("string '" + string + "' chosen");
        response.writeHead(200, {"Content-Type": "text/plain"});
        response.end(string);
        console.log("string sent");
    }else{
        fs.readFile('./index.html', function(err, file) {  
            if(err) {  
                // write an error response or nothing here  
                return;  
            }  
            response.writeHead(200, { 'Content-Type': 'text/html' });  
            response.end(file, "utf-8");  
        });
    }
}).listen(8001);
console.log("server initialized");

frontend (part of index.html):

function newGame()
{
   guessCnt=0;
   guess="";
   server();
   displayHash();
   displayGuessStr();
   displayGuessCnt();
}

function server()
{
   xmlhttp = new XMLHttpRequest();
   xmlhttp.open("GET","http://localhost:8001/getstring", true);
   xmlhttp.onreadystatechange=function(){
         if (xmlhttp.readyState==4 && xmlhttp.status==200){
           string=xmlhttp.responseText;
         }
   }
   xmlhttp.send();
}

You will need to be comfortable with AJAX. Use the mozilla learning center to learn about XMLHttpRequest. After you can use the basic XHR object, you will most likely want to use a good AJAX library instead of manually writing cross-browser AJAX requests (for example, in IE you'll need to use an ActiveXObject instead of XHR). The AJAX in jQuery is excellent, but if you don't need everything else jQuery offers, find a good AJAX library here: http://microjs.com/. You will also need to get comfy with the node.js docs, found here. Search http://google.com for some good node.js server and static file server tutorials. http://nodetuts.com is a good place to start.

UPDATE: I have changed response.sendHeader() to the new response.writeHead() in the code above !!!

I believe that Notepad++ has this feature.

Edit (for newer versions)
Install the "XML Tools" plugin (Menu Plugins, Plugin Manager)
Then run: Menu Plugins, Xml Tools, Pretty Print (XML only - with line breaks)

Original answer (for older versions of Notepad++)

Notepad++ menu: TextFX -> HTML Tidy -> Tidy: Reindent XML

This feature however wraps XMLs and that makes it look 'unclean'. To have no wrap,

• open C:\Program Files\Notepad++\plugins\Config\tidy\TIDYCFG.INI,
• find the entry [Tidy: Reindent XML] and add wrap:0 so that it looks like this:

[Tidy: Reindent XML] 
input-xml: yes 
indent:yes 
wrap:0 

In my opinion, the simplest way to get the amount of selected rows is the following:

The cursor object returns a list with the results when using the fetch commands (fetchall(), fetchone(), fetchmany()). To get the selected rows just print the length of this list. But it just makes sense for fetchall(). ;-)

Example:

print len(cursor.fetchall) 

just in case someone looks for this, the path to the file on Sourav answer (httpd.conf) in linux is /opt/lampp/etc/httpd.conf

In case you want a quicker (but still very clean) way of achieving it for a personal purpose (for instance if you want to build a specific project having some strong requirements concerning the version of the compiler), just follow the following steps:

• type echo $PATH and look for a personal directory having a very high priority (in my case, I have ~/.local/bin);
• add the symbolic links in this directory:

For instance:

ln -s /usr/bin/gcc-WHATEVER ~/.local/bin/gcc
ln -s /usr/bin/g++-WHATEVER ~/.local/bin/g++

Of course, this will work for a single user (it isn't a system wide solution), but on the other hand I don't like to change too many things in my installation.

You must change the cmake C/CXX default FLAGS .

According to CMAKE_BUILD_TYPE={DEBUG/MINSIZEREL/RELWITHDEBINFO/RELEASE} put in the main CMakeLists.txt one of :

For C

set(CMAKE_C_FLAGS_DEBUG "put your flags")
set(CMAKE_C_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_C_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_C_FLAGS_RELEASE "put your flags")

For C++

set(CMAKE_CXX_FLAGS_DEBUG "put your flags")
set(CMAKE_CXX_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_CXX_FLAGS_RELEASE "put your flags")

This will override the values defined in CMakeCache.txt

I have developed a very simple and fast package to do this kind of update, atualiza can deal with global and project packages. In the later you can choose between the newest version or the bigger version that matches your current package.json's rule. For global packages you don't have a rule so atualiza will upgrade to newest always.

You can pass --rcfile to Bash to cause it to read a file of your choice. This file will be read instead of your .bashrc. (If that's a problem, source ~/.bashrc from the other script.)

Edit: So a function to start a new shell with the stuff from ~/.more.sh would look something like:

more() { bash --rcfile ~/.more.sh ; }

... and in .more.sh you would have the commands you want to execute when the shell starts. (I suppose it would be elegant to avoid a separate startup file -- you cannot use standard input because then the shell will not be interactive, but you could create a startup file from a here document in a temporary location, then read it.)

To check if a Path exists to a directory, use this one:

$pathToDirectory = "c:\program files\blahblah\"
if (![System.IO.Directory]::Exists($pathToDirectory))
{
 mkdir $path1
}

To check if a Path to a file exists use what @Mathias suggested:

[System.IO.File]::Exists($pathToAFile)

There are 2 options to find matching text; string.match or string.find.

Both of these perform a regex search on the string to find matches.

string.find()

string.find(subject string, pattern string, optional start position, optional plain flag)

Returns the startIndex & endIndex of the substring found.

The plain flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger) being interpreted as a regex capture group matching for tiger, it instead looks for (tiger) within a string.

Going the other way, if you want to regex match but still want literal special characters (such as .()[]+- etc.), you can escape them with a percentage; %(tiger%).

You will likely use this in combination with string.sub

Example

str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

string.match()

string.match(s, pattern, optional index)

Returns the capture groups found.

Example

str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

No, because single-quotes even inhibit hex code replacement.

echo 'Hello, world!' . "\xA";

You should try this code.

 $("#multiple_Package_Ids_checkboxes").on('change', function (e) { 
        var totAmt = 0;
        $.each($(this).find(":selected"), function (i, item) { 
            totAmt += $(item).data("price");
            });
        $("#PackTotAmt").text(totAmt);
    }); 

The best way to do it is:

Step 1: Rename your main.css to main.php

Step 2: in your main.php add

<style> ... </style>

Step 3: include it as usual

<?php include 'main.php'; ?>

That is how i did it, and it works smoothly..

You want

strchr (const char *s, int c)

If the character c is in the string s it returns a pointer to the location in s. Otherwise it returns NULL. So just use your list of invalid characters as the string.

I just tested this and it works fine

var d = new Date(1441121836000);

The data object has a constructor which takes milliseconds as an argument.

While Ryan is correct, the solution can be much simpler based on what is known about the source of the randomness. To re-state the problem:

• There is a source of randomness, outputting integer numbers in range [0, MAX) with uniform distribution.
• The goal is to produce uniformly distributed random integer numbers in range [rmin, rmax] where 0 <= rmin < rmax < MAX.

In my experience, if the number of bins (or "boxes") is significantly smaller than the range of the original numbers, and the original source is cryptographically strong - there is no need to go through all that rigamarole, and simple modulo division would suffice (like output = rnd.next() % (rmax+1), if rmin == 0), and produce random numbers that are distributed uniformly "enough", and without any loss of speed. The key factor is the randomness source (i.e., kids, don't try this at home with rand()).

Here's an example/proof of how it works in practice. I wanted to generate random numbers from 1 to 22, having a cryptographically strong source that produced random bytes (based on Intel RDRAND). The results are:

Rnd distribution test (22 boxes, numbers of entries in each box):     
 1: 409443    4.55%
 2: 408736    4.54%
 3: 408557    4.54%
 4: 409125    4.55%
 5: 408812    4.54%
 6: 409418    4.55%
 7: 408365    4.54%
 8: 407992    4.53%
 9: 409262    4.55%
10: 408112    4.53%
11: 409995    4.56%
12: 409810    4.55%
13: 409638    4.55%
14: 408905    4.54%
15: 408484    4.54%
16: 408211    4.54%
17: 409773    4.55%
18: 409597    4.55%
19: 409727    4.55%
20: 409062    4.55%
21: 409634    4.55%
22: 409342    4.55%   
total: 100.00%

This is as close to uniform as I need for my purpose (fair dice throw, generating cryptographically strong codebooks for WWII cipher machines such as http://users.telenet.be/d.rijmenants/en/kl-7sim.htm, etc). The output does not show any appreciable bias.

Here's the source of cryptographically strong (true) random number generator: Intel Digital Random Number Generator and a sample code that produces 64-bit (unsigned) random numbers.

int rdrand64_step(unsigned long long int *therand)
{
  unsigned long long int foo;
  int cf_error_status;

  asm("rdrand %%rax; \
        mov $1,%%edx; \
        cmovae %%rax,%%rdx; \
        mov %%edx,%1; \
        mov %%rax, %0;":"=r"(foo),"=r"(cf_error_status)::"%rax","%rdx");
        *therand = foo;
  return cf_error_status;
}

I compiled it on Mac OS X with clang-6.0.1 (straight), and with gcc-4.8.3 using "-Wa,q" flag (because GAS does not support these new instructions).

If you just want to get the information of current directory, you can type:

pwd

and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.

About the .dex File :

One of the most remarkable features of the Dalvik Virtual Machine (the workhorse under the Android system) is that it does not use Java bytecode. Instead, a homegrown format called DEX was introduced and not even the bytecode instructions are the same as Java bytecode instructions.

Compiled Android application code file.

Android programs are compiled into .dex (Dalvik Executable) files, which are in turn zipped into a single .apk file on the device. .dex files can be created by automatically translating compiled applications written in the Java programming language.

Dex file format:

 1. File Header
 2. String Table
 3. Class List
 4. Field Table
 5. Method Table
 6. Class Definition Table
 7. Field List
 8. Method List
 9. Code Header
10. Local Variable List

Android has documentation on the Dalvik Executable Format (.dex files). You can find out more over at the official docs: Dex File Format

.dex files are similar to java class files, but they were run under the Dalkvik Virtual Machine (DVM) on older Android versions, and compiled at install time on the device to native code with ART on newer Android versions.

You can decompile .dex using the dexdump tool which is provided in android-sdk.

There are also some Reverse Engineering Techniques to make a jar file or java class file from a .dex file.

There is also a smaller one yet called "input-mini".

I used this for breadcrums in the category template page:

$cat_obj = $wp_query->get_queried_object();
$thiscat_id = $cat_obj->term_id;
$thiscat = get_category($thiscat_id);
$parentcat = get_category($thiscat->parent);

As stated by Taylor L, you can't just "stop" a thread (by calling a simple method) due to the fact that it could leave your system in an unstable state as the external calling thread may not know what is going on inside your thread.

With this said, the best way to "stop" a thread is to have the thread keep an eye on itself and to have it know and understand when it should stop.

tl;dr

I know this is old, but getoptlong wasn't mentioned here and it's probably the best way to parse command line arguments today.

Parsing command line arguments

I strongly recommend getoptlong. It's pretty easy to use and works like a charm. Here is an example extracted from the link above

require 'getoptlong'

opts = GetoptLong.new(
    [ '--help', '-h', GetoptLong::NO_ARGUMENT ],
    [ '--repeat', '-n', GetoptLong::REQUIRED_ARGUMENT ],
    [ '--name', GetoptLong::OPTIONAL_ARGUMENT ]
)

dir = nil
name = nil
repetitions = 1
opts.each do |opt, arg|
    case opt
        when '--help'
            puts <<-EOF
hello [OPTION] ... DIR

-h, --help:
     show help

--repeat x, -n x:
     repeat x times

--name [name]:
     greet user by name, if name not supplied default is John

DIR: The directory in which to issue the greeting.
            EOF
        when '--repeat'
            repetitions = arg.to_i
        when '--name'
            if arg == ''
                name = 'John'
            else
                name = arg
            end
    end
end

if ARGV.length != 1
    puts "Missing dir argument (try --help)"
    exit 0
end

dir = ARGV.shift

Dir.chdir(dir)
for i in (1..repetitions)
    print "Hello"
    if name
        print ", #{name}"
    end
    puts
end

You can call it like this ruby hello.rb -n 6 --name -- /tmp

What OP is trying to do

In this case I think the best option is to use YAML files as suggested in this answer

To set your Java path on mac:

1. Open terminal on mac, change path to the root cd ~
2. vi .bash_profile (This opens the bash_profile file)

3. Click I to insert text and use the following text to set JAVA_HOME and PATH

   • export JAVA_HOME='/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home'

   • export PATH=$JAVA_HOME/bin:$PATH

     4. Type :wq to save and exit the file.
     5. Type source .bash_profile to execute the .bash_profile file.
     6. You can type echo $JAVA_HOME or echo $PATH

THIRD VERSION OF MY ANSWER:

Here's a multiple line example of inline Jade Javascript. I don't think you can write it without using a -. This is a flash message example that I use in a partial. Hope this helps!

-if(typeof(info) !== 'undefined')
  -if (info)
    - if(info.length){
      ul
        -info.forEach(function(info){
          li= info
      -})
  -}

Is the code you're trying to get to compile the code in your question?

If so, you don't need two things: first, you don't need to declare that it's Javascript/a script, you can just started coding after typing -; second, after you type -if you don't need to type the { or } either. That's what makes Jade pretty sweet.

--------------ORIGINAL ANSWER BELOW ---------------

Try prepending if with -:

-if(10 == 10)
  //do whatever you want here as long as it's indented two spaces from
   the `-` above

There are also tons of Jade examples at:

HTML

<img src="images/bg.jpg" id="bg" alt="">

CSS

#bg {
  position: fixed; 
  top: 0; 
  left: 0; 

  /* Preserve aspet ratio */
  min-width: 100%;
  min-height: 100%;
}

Solution:

sort -k 2 -n filename

more verbosely written as:

sort --key 2 --numeric-sort filename

Example:

$ cat filename
A 12
B 48
C 3

$ sort --key 2 --numeric-sort filename 
C 3
A 12
B 48

Explanation:

• -k # - this argument specifies the first column that will be used to sort. (note that column here is defined as a whitespace delimited field; the argument -k5 will sort starting with the fifth field in each line, not the fifth character in each line)

• -n - this option specifies a "numeric sort" meaning that column should be interpreted as a row of numbers, instead of text.

More:

Other common options include:

• -r - this option reverses the sorting order. It can also be written as --reverse.
• -i - This option ignores non-printable characters. It can also be written as --ignore-nonprinting.
• -b - This option ignores leading blank spaces, which is handy as white spaces are used to determine the number of rows. It can also be written as --ignore-leading-blanks.
• -f - This option ignores letter case. "A"=="a". It can also be written as --ignore-case.
• -t [new separator] - This option makes the preprocessing use a operator other than space. It can also be written as --field-separator.

There are other options, but these are the most common and helpful ones, that I use often.

If you have just a few columns to sum, you can write:

df['e'] = df['a'] + df['b'] + df['d']

This creates new column e with the values:

   a  b   c  d   e
0  1  2  dd  5   8
1  2  3  ee  9  14
2  3  4  ff  1   8

For longer lists of columns, EdChum's answer is preferred.

What I ended up doing is create a new KeyContainer name based off of the current DateTime (DateTime.Now.Ticks.ToString()) whenever I need to create a new key and save the container name and public key to the database. Also, whenever I create a new key I would do the following:

public static string ConvertToNewKey(string oldPrivateKey)
{

    // get the current container name from the database...

    rsa.PersistKeyInCsp = false;
    rsa.Clear();
    rsa = null;

    string privateKey = AssignNewKey(true); // create the new public key and container name and write them to the database...

       // re-encrypt existing data to use the new keys and write to database...

    return privateKey;
}
public static string AssignNewKey(bool ReturnPrivateKey){
     string containerName = DateTime.Now.Ticks.ToString();
     // create the new key...
     // saves container name and public key to database...
     // and returns Private Key XML.
}

before creating the new key.

Criteria is an object-oriented API, while HQL means string concatenation. That means all of the benefits of object-orientedness apply:

1. All else being equal, the OO version is somewhat less prone to error. Any old string could get appended into the HQL query, whereas only valid Criteria objects can make it into a Criteria tree. Effectively, the Criteria classes are more constrained.
2. With auto-complete, the OO is more discoverable (and thus easier to use, for me at least). You don't necessarily need to remember which parts of the query go where; the IDE can help you
3. You also don't need to remember the particulars of the syntax (like which symbols go where). All you need to know is how to call methods and create objects.

Since HQL is very much like SQL (which most devs know very well already) then these "don't have to remember" arguments don't carry as much weight. If HQL was more different, then this would be more importatnt.

from os.path import dirname, realpath, join
join(dirname(realpath(dirname(__file__))), 'templates')

Update:

If you happen to "copy" settings.py through symlinking, @forivall's answer is better:

~user/
    project1/  
        mysite/
            settings.py
        templates/
            wrong.html

    project2/
        mysite/
            settings.py -> ~user/project1/settings.py
        templates/
            right.html

The method above will 'see' wrong.html while @forivall's method will see right.html

In the absense of symlinks the two answers are identical.

I tried with many solutions but it didn't work for me so I tried flex with the table and it worked fine for me with all table functionalities like border-collapse and so on only change is display property

This was my HTML requirement

<table>
  <thead>
    <tr>
      <th>1</th>
      <th colspan="3">2</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>1</td>
      <td colspan="3">2</td>
    </tr>
    <tr>
      <td>1</td>
      <td>2</td>
      <td>3</td>
      <td>4</td>
    </tr>
    <tr>
      <td>1</td>
      <td>2</td>
      <td colspan="2">3</td>
    </tr>
  </tbody>
</table>

My CSS

table{
    display: flex;
  flex-direction: column;
}
table tr{
    display: flex;
  width: 100%;
}
table > thead > tr > th:first-child{
    width: 20%;
}
table > thead > tr > th:last-child{
    width: 80%;
}
table > tbody tr > td:first-child{
    width: 10%;
}
table > tbody tr > td{
    width: 30%;
}
table > tbody tr > td[colspan="2"]{
    width: 60%;
}
table > tbody tr > td[colspan="3"]{
    width: 90%;
}
/*This is to remove border making 1px space on right*/
table > tbody tr > td:last-child{
    border-right: 0;
}

value_counts work only for series. It won't work for entire DataFrame. Try selecting only one column and using this attribute. For example:

df['accepted'].value_counts()

It also won't work if you have duplicate columns. This is because when you select a particular column, it will also represent the duplicate column and will return dataframe instead of series. At that time remove duplicate column by using

df = df.loc[:,~df.columns.duplicated()]
df['accepted'].value_counts()

Granted, there are definitely different thinking, in my world, I cannot enforce "Never pass a null" because I am dealing with uncontrollable third parties like API callers, database records, former programmers etc... so I am paranoid and defensive in approaches. Since you are on Java8 or later there is a bit cleaner approach than an if block.

public String foo(@Nullable String mayBeNothing) {
   return Optional.ofNullable(mayBeNothing).orElse("Really Nothing");
}

You can also throw some exception in there by swapping .orElse to orElseThrow(() -> new Exception("Dont' send a null")).

If you don't want to use @Nullable, which adds nothing functionally, why not just name the parameter with mayBe... so your intention is clear.

Check permissions of the file, if it is good check parent directories

I had to correct

/home/sravindr/.ssh permissions which worked for me

            </plugin>

this configuration excludes the GlobalExceptionHandler.java and ErrorResponse.java in the jacoco coverage.

And the following two lines does the same for sonar coverage .

    <sonar.exclusions> **/*GlobalExceptionHandler*.*, **/*ErrorResponse*.</sonar.exclusions>
        <sonar.coverage.exclusions> **/*GlobalExceptionHandler*.*, **/*ErrorResponse*.* </sonar.coverage.exclusions>

Almost same as greatbear302's answer, but i create ContractResolver per request.

1) Create a custom ContractResolver

public class MyJsonContractResolver : DefaultContractResolver
{
    public List<Tuple<string, string>> ExcludeProperties { get; set; }

    protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
    {
        JsonProperty property = base.CreateProperty(member, memberSerialization);

        if (ExcludeProperties?.FirstOrDefault(
            s => s.Item2 == member.Name && s.Item1 == member.DeclaringType.Name) != null)
        {
            property.ShouldSerialize = instance => { return false; };
        }

        return property;
    }
}

2) Use custom contract resolver in action

public async Task<IActionResult> Sites()

It didn't work as expected(isolate resolver per request). I'll use anonymous objects.

In general if you are using the Package Manager Console the right way to remove a specific Migration is by referencing the name of the migration

Update-Database -Migration {Name of Migration} -Context {context}

Another way to remove the last migration you have applied according to the docs is by using the command:

dotnet ef migrations remove

This command should be executed from the developer command prompt (how to open command prompt) inside your solution directory.

For example if your application is inside name "Application" and is in the folder c:\Projects. Then your path should be:

C:\Projects\Application

To split a string s, the easiest way is to pass it to list(). So,

s = 'abc'
s_l = list(s) #  s_l is now ['a', 'b', 'c']

You can also use a list comprehension, which works but is not as concise as the above:

s_l = [c for c in s]

There are other ways, as well, but these should suffice. Later, if you want to recombine them, a simple call to "".join(s_l) will return your list to all its former glory as a string...

The script from gombosg is much better then npm-check.
I have modified a little bit, so devdependencies in node_modules will also be found.
example sass never used, but needed in sass-loader

#!/bin/bash
DIRNAME=${1:-.}
cd $DIRNAME

FILES=$(mktemp)
PACKAGES=$(mktemp)

# use fd
# https://github.com/sharkdp/fd

function check {
    cat package.json \
        | jq "{} + .$1 | keys" \
        | sed -n 's/.*"\(.*\)".*/\1/p' > $PACKAGES
    echo "--------------------------"
    echo "Checking $1..."
    fd '(js|ts|json)$' -t f > $FILES
    while read PACKAGE
    do
        if [ -d "node_modules/${PACKAGE}" ]; then
            fd  -t f '(js|ts|json)$' node_modules/${PACKAGE} >> $FILES
        fi
        RES=$(cat $FILES | xargs -I {} egrep -i "(import|require|loader|plugins|${PACKAGE}).*['\"](${PACKAGE}|.?\d+)[\"']" '{}' | wc -l)

        if [ $RES = 0 ]
        then
            echo -e "UNUSED\t\t $PACKAGE"
        else
            echo -e "USED ($RES)\t $PACKAGE"
        fi
    done < $PACKAGES

Several of Unicode character ranges are valid HTML5, although it might still not be a good idea to use them.

E.g., href docs say http://www.w3.org/TR/html5/links.html#attr-hyperlink-href:

The href attribute on a and area elements must have a value that is a valid URL potentially surrounded by spaces.

Then the definition of "valid URL" points to http://url.spec.whatwg.org/, which says it aims to:

Align RFC 3986 and RFC 3987 with contemporary implementations and obsolete them in the process.

That document defines URL code points as:

ASCII alphanumeric, "!", "$", "&", "'", "(", ")", "*", "+", ",", "-", ".", "/", ":", ";", "=", "?", "@", "_", "~", and code points in the ranges U+00A0 to U+D7FF, U+E000 to U+FDCF, U+FDF0 to U+FFFD, U+10000 to U+1FFFD, U+20000 to U+2FFFD, U+30000 to U+3FFFD, U+40000 to U+4FFFD, U+50000 to U+5FFFD, U+60000 to U+6FFFD, U+70000 to U+7FFFD, U+80000 to U+8FFFD, U+90000 to U+9FFFD, U+A0000 to U+AFFFD, U+B0000 to U+BFFFD, U+C0000 to U+CFFFD, U+D0000 to U+DFFFD, U+E1000 to U+EFFFD, U+F0000 to U+FFFFD, U+100000 to U+10FFFD.

The term "URL code points" is then used in the statement:

If c is not a URL code point and not "%", parse error.

in a several parts of the parsing algorithm, including the schema, authority, relative path, query and fragment states: so basically the entire URL.

Also, the validator http://validator.w3.org/ passes for URLs like "??", and does not pass for URLs with characters like spaces "a b"

Of course, as mentioned by Stephen C, it is not just about characters but also about context: you have to understand the entire algorithm. But since class "URL code points" is used on key points of the algorithm, it that gives a good idea of what you can use or not.

        Note:
        1) Both ++ and * have same precedence(priority), so the associativity comes into picture.
        2) in this case Associativity is from **Right-Left**

        important table to remember in case of pointers and arrays: 

        operators           precedence        associativity

    1)  () , []                1               left-right
    2)  *  , identifier        2               right-left
    3)  <data type>            3               ----------

        let me give an example, this might help;

        char **str;
        str = (char **)malloc(sizeof(char*)*2); // allocate mem for 2 char*
        str[0]=(char *)malloc(sizeof(char)*10); // allocate mem for 10 char
        str[1]=(char *)malloc(sizeof(char)*10); // allocate mem for 10 char

        strcpy(str[0],"abcd");  // assigning value
        strcpy(str[1],"efgh");  // assigning value

        while(*str)
        {
            cout<<*str<<endl;   // printing the string
            *str++;             // incrementing the address(pointer)
                                // check above about the prcedence and associativity
        }
        free(str[0]);
        free(str[1]);
        free(str);

Since C# 7.0 supports using static directive and Local functions you don't need preprocessor macros for most cases.

May be helpful... :)

$(document).ready(function() {
    $('#buutonId').on('click', function() {
        $('#modalId').modal('open');
    });
});

You can now simply get a list of event listeners bound to an object by using the javascript function getEventListeners().

For example type the following in the dev tools console:

// Get all event listners bound to the document object
getEventListeners(document);

In the latest version of Angular (as of 1.1.5), they have included a conditional directive called ngIf. It is different from ngShow and ngHide in that the elements aren't hidden, but not included in the DOM at all. They are very useful for components which are costly to create but aren't used:

<div ng-if="video == video.large">
    <!-- code to render a large video block-->
</div>
<div ng-if="video != video.large">
    <!-- code to render the regular video block -->
</div>

The LoggerFactory class is msising according to the error message:

java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory

Apparently, the slf4j.jar file is not getting loaded for some reason.

In phpmyadmin, you can assign Foreign key simply by its GUI. Click on the table and go to Structure tab. find the Relation View on just bellow of table (shown in below image).

You can assign the forging key from the list box near by the primary key.(See image below). and save

corresponding SQL query automatically generated and executed.

Sure you can debug using this mode {{ PDO::ATTR_ERRMODE }} Just add new line before your query then you will show the debug lines.

$db->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );
$db->query('SELECT *******');  

You need to define a copy constructor, assignment, operator.

class Test {
   Test(const Test &that); //Copy constructor
   Test& operator= (const Test &rhs); //assignment operator
}

Your copy that is pushed on the queue is pointing to the same memory your original is. When the first is destructed, it deletes the memory. The second destructs and tries to delete the same memory.

In python 3 urllib2 was merged into urllib. See also another Stack Overflow question and the urllib PEP 3108.

To make Python 2 code work in Python 3:

try:
    import urllib.request as urllib2
except ImportError:
    import urllib2

as a beginner, i import acm packages, and in this package, run() starts executing of a thread, init() initialize the Java Applet.

Here is another way how you can format using 'f-string' format:

print(
    f"{'Trades:':<15}{cnt:>10}",
    f"\n{'Wins:':<15}{wins:>10}",
    f"\n{'Losses:':<15}{losses:>10}",
    f"\n{'Breakeven:':<15}{evens:>10}",
    f"\n{'Win/Loss Ratio:':<15}{win_r:>10}",
    f"\n{'Mean Win:':<15}{mean_w:>10}",
    f"\n{'Mean Loss:':<15}{mean_l:>10}",
    f"\n{'Mean:':<15}{mean_trd:>10}",
    f"\n{'Std Dev:':<15}{sd:>10}",
    f"\n{'Max Loss:':<15}{max_l:>10}",
    f"\n{'Max Win:':<15}{max_w:>10}",
    f"\n{'Sharpe Ratio:':<15}{sharpe_r:>10}",
)

This will provide the following output:

Trades:              2304
Wins:                1232
Losses:              1035
Breakeven:             37
Win/Loss Ratio:      1.19
Mean Win:           0.381
Mean Loss:         -0.395
Mean:               0.026
Std Dev:             0.56
Max Loss:          -3.406
Max Win:             4.09
Sharpe Ratio:      0.7395

What you are doing here is you are saying that the first column is 15 chars long and it's left justified and second column (values) is 10 chars long and it's right justified.

Your divider may not be showing due to too large dividerPadding. You set 22dip, that means the divider is truncated by 22dip from top and by 22dip from bottom. If your layout height is less than or equal 44dip then no divider is visible.

Simplest way:

def isSorted(arr):
  i = 1
  while i < len(arr):
    if(result[i] < result[i - 1]):
      return False
    i += 1
  return True

It depends on the coding standard I'm working under. If we are using _ to denote an instance variable then "this" becomes redundant. If we are not using _ then I tend to use this to denote instance variable.

In theory everything is possible but reality you find the numbers much lower than you might expect. I have been trying to address huge spaces on servers often and found that even though a server can have huge amounts of memory it surprised me that most software actually never can address it in real scenario's simply because the cpu's are not fast enough to really address them. Why would you say right ?! . Timings thats the endless downfall of every enormous machine which i have worked on. So i would advise to not go overboard by addressing huge amounts just because you can, but use what you think could be used. Actual values are often much lower than what you expected. Ofcourse non of us really uses hp 9000 systems at home and most of you actually ever will go near the capacity of your home system ever. For instance most users do not have more than 16 Gb of memory in their system. Ofcourse some of the casual gamers use work stations for a game once a month but i bet that is a very small percentage. So coming down to earth means i would address on a 8 Gb 64 bit system not much more than 512 mb for heapspace or if you go overboard try 1 Gb. I am pretty sure its even with these numbers pure overkill. I have constant monitored the memory usage during gaming to see if the addressing would make any difference but did not notice any difference at all when i addressed much lower values or larger ones. Even on the server/workstations there was no visible change in performance no matter how large i set the values. That does not say some jave users might be able to make use of more space addressed, but this far i have not seen any of the applications needing so much ever. Ofcourse i assume that their would be a small difference in performance if java instances would run out of enough heapspace to work with. This far i have not found any of it at all, however lack of real installed memory showed instant drops of performance if you set too much heapspace. When you have a 4 Gb system you run quickly out of heapspace and then you will see some errors and slowdowns because people address too much space which actually is not free in the system so the os starts to address drive space to make up for the shortage hence it starts to swap.

-Xmn : the size of the heap for the young generation Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor" .

Good size is 33%

Lint was the name of a program that would go through your C code and identify problems before you compiled, linked, and ran it. It was a static checker, much like FindBugs today for Java.

Like Google, "lint" became a verb that meant static checking your source code.

Working with floats is bit messy:

This as many other 'trivial' layout tricks can be done with flexbox.

   div.container {
     display: flex;
     justify-content: space-between;
   }

In 2017 I think this is preferred solution (over float) if you don't have to support legacy browsers: https://caniuse.com/#feat=flexbox

Check fiddle how different float usages compares to flexbox ("may include some competing answers"): https://jsfiddle.net/b244s19k/25/. If you still need to stick with float I recommended third version of course.

Ctrl + S, saves the entire fiddle, inside the files folder there is the clean page you are looking for

Avoid using "if (!jQuery)" since IE will return the error: jQuery is 'undefined'

Instead use: if (typeof jQuery == 'undefined')

<script type="text/javascript">
if (typeof jQuery == 'undefined') {
    var script = document.createElement('script');
    script.type = "text/javascript";
    script.src = "http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js";
    document.getElementsByTagName('head')[0].appendChild(script);
}
</script>

You'll also need to check if the JQuery has loaded after appending it to the header. Otherwise you'll have to wait for the window.onload event, which is slower if the page has images. Here's a sample script which checks if the JQuery file has loaded, since you won't have the convenience of being able to use $(document).ready(function...

You just have to set UIFileSharingEnabled (Application Supports iTunes file sharing) key in the info plist of your app. Here's a link for the documentation. Scroll down to the file sharing support part.

In the past, it was also necessary to define CFBundleDisplayName (Bundle Display Name), if it wasn't already there. More details here.

WebSocket is basically an application protocol (with reference to the ISO/OSI network stack), message-oriented, which makes use of TCP as transport layer.

The idea behind the WebSocket protocol consists of reusing the established TCP connection between a Client and Server. After the HTTP handshake the Client and Server start speaking WebSocket protocol by exchanging WebSocket envelopes. HTTP handshaking is used to overcome any barrier (e.g. firewalls) between a Client and a Server offering some services (usually port 80 is accessible from anywhere, by anyone). Client and Server can switch over speaking HTTP in any moment, making use of the same TCP connection (which is never released).

Behind the scenes WebSocket rebuilds the TCP frames in consistent envelopes/messages. The full-duplex channel is used by the Server to push updates towards the Client in an asynchronous way: the channel is open and the Client can call any futures/callbacks/promises to manage any asynchronous WebSocket received message.

To put it simply, WebSocket is a high level protocol (like HTTP itself) built on TCP (reliable transport layer, on per frame basis) that makes possible to build effective real-time application with JS Clients (previously Comet and long-polling techniques were used to pull updates from the Server before WebSockets were implemented. See Stackoverflow post: Differences between websockets and long polling for turn based game server ).

http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.remoteendpoint.aspx

You can then call the IPEndPoint..::.Address method to retrieve the remote IPAddress, and the IPEndPoint..::.Port method to retrieve the remote port number.

More from the link (fixed up alot heh):

Socket s;

IPEndPoint remoteIpEndPoint = s.RemoteEndPoint as IPEndPoint;
IPEndPoint localIpEndPoint = s.LocalEndPoint as IPEndPoint;

if (remoteIpEndPoint != null)
{
    // Using the RemoteEndPoint property.
    Console.WriteLine("I am connected to " + remoteIpEndPoint.Address + "on port number " + remoteIpEndPoint.Port);
}

if (localIpEndPoint != null)
{
    // Using the LocalEndPoint property.
    Console.WriteLine("My local IpAddress is :" + localIpEndPoint.Address + "I am connected on port number " + localIpEndPoint.Port);
}
