The 'pidof' command will not display pids of shell/perl/python scripts. So to find the process id’s of my Perl script I had to use the -x option i.e. 'pidof -x perlscriptname'

The issue is caused because of event bubbling. The first part of your code to add .grown works fine.

The second part "removing grown class" on clicking the link doesn't work as expected as both the handler for .close_button and .clickable are executed. So it removes and readd the grown class to the div.

You can avoid this by using e.stopPropagation() inside .close_button click handler to avoid the event from bubbling.

DEMO: http://jsfiddle.net/vL8DP/

Full Code

$(document).on('click', '.clickable', function () {
   $(this).addClass('grown').removeClass('spot');
}).on('click', '.close_button', function (e) {
   e.stopPropagation();
   $(this).closest('.clickable').removeClass('grown').addClass('spot');
});

What I need is to use Docker with MariaDb on different port /3301/ on my Ubuntu machine because I already had MySql installed and running on 3306.

To do this after half day searching did it using:

docker run -it -d -p 3301:3306 -v ~/mdbdata/mariaDb:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root --name mariaDb mariadb

This pulls the image with latest MariaDb, creates container called mariaDb, and run mysql on port 3301. All data of which is located in home directory in /mdbdata/mariaDb.

To login in mysql after that can use:

mysql -u root -proot -h 127.0.0.1 -P3301

To handle undefined variables as well as nulls, you can use substitute with deparse:

nullSafe <- function(x) {
  if (!exists(deparse(substitute(x))) || is.null(x)) {
    return(NA)
  } else {
    return(x)
  }
}

nullSafe(my.nonexistent.var)

That doesn't set the format of the string; it sets the format of the file. Even with that header, "hello" is a byte string, not a Unicode string. To make it Unicode, you're going to have to use u"hello" everywhere. The header is just a hint of what format to use when reading the .py file.

ECMAScript 2015 (or ES6) came with built-in Reflect object. It is possible to delete object property by calling Reflect.deleteProperty() function with target object and property key as parameters:

Reflect.deleteProperty(myJSONObject, 'regex');

which is equivalent to:

delete myJSONObject['regex'];

But if the property of the object is not configurable it cannot be deleted neither with deleteProperty function nor delete operator:

let obj = Object.freeze({ prop: "value" });
let success = Reflect.deleteProperty(obj, "prop");
console.log(success); // false
console.log(obj.prop); // value

Object.freeze() makes all properties of object not configurable (besides other things). deleteProperty function (as well as delete operator) returns false when tries to delete any of it's properties. If property is configurable it returns true, even if property does not exist.

The difference between delete and deleteProperty is when using strict mode:

"use strict";

let obj = Object.freeze({ prop: "value" });
Reflect.deleteProperty(obj, "prop"); // false
delete obj["prop"];
// TypeError: property "prop" is non-configurable and can't be deleted

A quick definition of the "permanent generation":

"The permanent generation is used to hold reflective data of the VM itself such as class objects and method objects. These reflective objects are allocated directly into the permanent generation, and it is sized independently from the other generations." [ref]

In other words, this is where class definitions go (and this explains why you may get the message OutOfMemoryError: PermGen space if an application loads a large number of classes and/or on redeployment).

Note that PermSize is additional to the -Xmx value set by the user on the JVM options. But MaxPermSize allows for the JVM to be able to grow the PermSize to the amount specified. Initially when the VM is loaded, the MaxPermSize will still be the default value (32mb for -client and 64mb for -server) but will not actually take up that amount until it is needed. On the other hand, if you were to set BOTH PermSize and MaxPermSize to 256mb, you would notice that the overall heap has increased by 256mb additional to the -Xmx setting.

Change Minute to be 0. That's it :)

I've got a one liner to make HTML Tables look BootStrapped:

<table class="table table-striped table-bordered table-hover">

The theme suits other controls and it supports alternate row highlighting.

num1 and num2 are Long objects. You should be using equals() to compare them. == comparison might work sometimes because of the way JVM boxes primitives, but don't depend on it.

if (num1.equals(num1))

All Posted files will be come in $_FILES variable, for use codeigniter upload library we need to give field_name that we are using in for upload (by default it will be 'userfile'), so we get all posted file and create another files array that create our own name for each files, and give this name to codeigniter library do_upload function.

Use money-rails gem. It nicely handles money and currencies in your model and also has a bunch of helpers to format your prices.

Just try this:

DF %>% t %>% na.omit %>% t

It transposes the data frame and omits null rows which were 'columns' before transposition and then you transpose it back.

    var string = "hello",
    substring = "lo";
    string.includes(substring);

2. ES5 and older indexOf

    substring = "lo";
    string.indexOf(substring) !== -1;

You could run: mvn exec:exec -Dexec.args="arg1".

This will pass the argument arg1 to your program.

You should specify the main class fully qualified, for example, a Main.java that is in a package test would need

mvn exec:java  -Dexec.mainClass=test.Main

By using the -f parameter, as decribed here, you can also run it from other directories.

mvn exec:java -Dexec.mainClass=test.Main -f folder/pom.xm

For multiple arguments, simply separate them with a space as you would at the command line.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="arg1 arg2 arg3"

For arguments separated with a space, you can group using 'argument separated with space' inside the quotation marks.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="'argument separated with space' 'another one'"

Building off of Mamboking's answer:

ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(anyString())).thenReturn("Some result");

m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work(); 

Addressing your request to verify whether the argument contains a certain value, I could assume you mean that the argument is a String and you want to test whether the String argument contains a substring. For this you could do:

ArgumentCaptor<String> savedCaptor = ArgumentCaptor.forClass(String.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains("substring I want to find");

If that assumption was wrong, and the argument to save() is a collection of some kind, it would be only slightly different:

ArgumentCaptor<Collection<MyType>> savedCaptor = ArgumentCaptor.forClass(Collection.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains(someMyTypeElementToFindInCollection);

You might also check into ArgumentMatchers, if you know how to use Hamcrest matchers.

It is just a typo(I guess)-

p+=1;

instead of p +1=p; is required .

As name suggest lvalue expression should be left-hand operand of the assignment operator.

The SQLite command line utility has a .schema TABLENAME command that shows you the create statements.

In C the char type has a numeric value so the > operator will work just fine for example

#include <stdio.h>
main() {

    char a='z';

    char b='h';

    if ( a > b ) {
        printf("%c greater than %c\n",a,b);
    }
}

The following checklink.cmd program is a good place to start. It relies on the fact that you can do a single-shot ping and that, if successful, the output will contain the line:

Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),

By extracting tokens 5 and 7 and checking they're respectively "Received" and "1,", you can detect the success.

@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
:loop
set state=down
for /f "tokens=5,6,7" %%a in ('ping -n 1 !ipaddr!') do (
    if "x%%b"=="xunreachable." goto :endloop
    if "x%%a"=="xReceived" if "x%%c"=="x1,"  set state=up
)
:endloop
echo.Link is !state!
ping -n 6 127.0.0.1 >nul: 2>nul:
goto :loop
endlocal

Call it with the name (or IP address) you want to test:

checklink 127.0.0.1
checklink localhost
checklink nosuchaddress

Take into account that, if your locale is not English, you must replace Received with the corresponding keyword in your locale, for example recibidos for Spanish. Do a test ping to discover what keyword is used in your locale.

To only notify you when the state changes, you can use:

@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
set oldstate=neither
:loop
set state=down
for /f "tokens=5,7" %%a in ('ping -n 1 !ipaddr!') do (
    if "x%%a"=="xReceived" if "x%%b"=="x1," set state=up
)
if not !state!==!oldstate! (
    echo.Link is !state!
    set oldstate=!state!
)
ping -n 2 127.0.0.1 >nul: 2>nul:
goto :loop
endlocal

However, as Gabe points out in a comment, you can just use ERRORLEVEL so the equivalent of that second script above becomes:

@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
set oldstate=neither
:loop
set state=up
ping -n 1 !ipaddr! >nul: 2>nul:
if not !errorlevel!==0 set state=down
if not !state!==!oldstate! (
    echo.Link is !state!
    set oldstate=!state!
)
ping -n 2 127.0.0.1 >nul: 2>nul:
goto :loop
endlocal

You can save it as .txt and change it manually using a mouse click and your keyboard. OR, when saving the file:

• choose All types(*.*) in the Save as type field.
• type filename.json in File name field

As the 64bit version is an x86 architecture and was accordingly first called x86-64, that would be the most appropriate name, IMO. Also, x32 is a thing (as mentioned before)—‘x64’, however, is not a continuation of that, so is (theoretically) missleading (even though many people will know what you are talking about) and should thus only be recognised as a marketing thing, not an ‘official’ architecture (again, IMO–obviously, others disagree).

I had to struggle for a little bit but I found a solution, I added

-Dsonar.coverage.exclusions=**/*.* 

and the coverage metric was cancelled from the dashboard at all, so I realized that the problem was the path I was passing, not the property. In my case the path to exclude was java/org/acme/exceptions, so I used :

`-Dsonar.coverage.exclusions=**/exceptions/**/*.*` 

and it worked, but since I don't have sub-folders it also works with

-Dsonar.coverage.exclusions=**/exceptions/*.*

Please try this. You will understand all perfectly after you will take a look on my solution.

There are only 2 ways of creating threads in java

with implements Runnable

class One implements Runnable {
@Override
public void run() {
    System.out.println("Running thread 1 ... ");
}

with extends Thread

class Two extends Thread {
@Override
public void run() {
    System.out.println("Running thread 2 ... ");
}

Your MAIN class here

public class ExampleMain {
public static void main(String[] args) {

    One demo1 = new One();
    Thread t1 = new Thread(demo1);
    t1.start();

    Two demo2 = new Two();
    Thread t2 = new Thread(demo2);
    t2.start();
}

}

it doesn't work because you have not programmed a fail-safe into the code. java sees that the scanner can still collect input while there is input to be collected and if possible, while that is true, it keeps doing so. having a scanner test to see if a certain word, like EXIT for example, is fine, but you could also have it loop a certain number of times, like ten or so. but the most efficient approach is to ask the user of your program how many strings they wish to enter, and while the number of strings they enter is less than the number they put in, the program shall execute. an added option could be if they type EXIT, when they see they need less spaces than they put in and don't want to fill the next cells up with nothing but whitespace. and you could have the program ask if they want to enter more input, in case they realize they need to enter more data into the computer. the program would be quite simplistic to make, as well because there are a plethera of ways you could do it. feel free to ask me for these ways, i'm running out of room though.

A nice and easy way for those people who always forget the command axhline is the following

plt.plot(x, [y]*len(x))

In your case xs = x and y = 40. If len(x) is large, then this becomes inefficient and you should really use axhline.

Faster way of doing this:

WHERE interests LIKE '%sports%' OR interests LIKE '%pub%'

is this:

WHERE interests REGEXP 'sports|pub'

$count = Model::where('status','=','1')->count();

or

$count = Model::count();

break interacts solely with the closest enclosing loop or switch, whether it be a for, while or do .. while type. It is frequently referred to as a goto in disguise, as all loops in C can in fact be transformed into a set of conditional gotos:

for (A; B; C) D;
// translates to
A;
goto test;
loop: D;
iter: C;
test: if (B) goto loop;
end:

while (B) D;          // Simply doesn't have A or C
do { D; } while (B);  // Omits initial goto test
continue;             // goto iter;
break;                // goto end;

The difference is, continue and break interact with virtual labels automatically placed by the compiler. This is similar to what return does as you know it will always jump ahead in the program flow. Switches are slightly more complicated, generating arrays of labels and computed gotos, but the way break works with them is similar.

The programming error the notice refers to is misunderstanding break as interacting with an enclosing block rather than an enclosing loop. Consider:

for (A; B; C) {
   D;
   if (E) {
       F;
       if (G) break;   // Incorrectly assumed to break if(E), breaks for()
       H;
   }
   I;
}
J;

Someone thought, given such a piece of code, that G would cause a jump to I, but it jumps to J. The intended function would use if (!G) H; instead.

Another example of the same concept - but say - you have 2 different columns - and you want to apply different agg functions to each of them i.e

f.groupBy("col1").agg(sum("col2").alias("col2"), avg("col3").alias("col3"), ...)

Here is the way to achieve it - though I do not yet know how to add the alias in this case

See the example below - Using Maps

val Claim1 = StructType(Seq(StructField("pid", StringType, true),StructField("diag1", StringType, true),StructField("diag2", StringType, true), StructField("allowed", IntegerType, true), StructField("allowed1", IntegerType, true)))
val claimsData1 = Seq(("PID1", "diag1", "diag2", 100, 200), ("PID1", "diag2", "diag3", 300, 600), ("PID1", "diag1", "diag5", 340, 680), ("PID2", "diag3", "diag4", 245, 490), ("PID2", "diag2", "diag1", 124, 248))

val claimRDD1 = sc.parallelize(claimsData1)
val claimRDDRow1 = claimRDD1.map(p => Row(p._1, p._2, p._3, p._4, p._5))
val claimRDD2DF1 = sqlContext.createDataFrame(claimRDDRow1, Claim1)

val l = List("allowed", "allowed1")
val exprs = l.map((_ -> "sum")).toMap
claimRDD2DF1.groupBy("pid").agg(exprs) show false
val exprs = Map("allowed" -> "sum", "allowed1" -> "avg")

claimRDD2DF1.groupBy("pid").agg(exprs) show false

The new way to do it is to use enabledBorder like this:

new TextField(
  decoration: new InputDecoration(
    enabledBorder: const OutlineInputBorder(
      borderSide: const BorderSide(color: Colors.grey, width: 0.0),
    ),
    focusedBorder: ...
    border: ...
  ),
)

You are inserting not Updating the result. You can define the name column in primary column or set it is unique.

Use ?? instead or {{ $usersType ?? '' }}

it's amazing there's no simple solution for such a simple task on windows, I created this little cmd script that you can use to define aliases on windows (instructions are at the file header itself):

https://gist.github.com/benjamine/5992592

this is pretty much the same approach used by tools like NPM or ruby gems to register global commands.

Here's an example on how you can do it :)

var students = [{_x000D_
    name: "Mike",_x000D_
    track: "track-a",_x000D_
    achievements: 23,_x000D_
    points: 400,_x000D_
  },_x000D_
  {_x000D_
    name: "james",_x000D_
    track: "track-a",_x000D_
    achievements: 2,_x000D_
    points: 21,_x000D_
  },_x000D_
]_x000D_
_x000D_
students.forEach(myFunction);_x000D_
_x000D_
function myFunction(item, index) {_x000D_
  for (var key in item) {_x000D_
    console.log(item[key])_x000D_
  }_x000D_
}

There are a number of different options, based on what exactly the effect you're going for is. Chris Coyier did a piece on just this way back when. Worth a read:

I am running Ubuntu 16.04 (Xenial Xerus). This is what worked for me:

1. Open up a terminal and cd to /etc/apache2/sites-available. There you will find a file called 000-default.conf.
2. Copy that file: cp 000-default.conf example.local.conf
3. Open that new file (I use Nano; use what you are comfortable with).
4. You will see a lot of commented lines, which you can delete.
5. Change <VirtualHost *:80> to <VirtualHost example.local:80>
6. Change the document root to reflect the location of your files.
7. Add the following line: ServerName example.local And if you need to, add this line: ServerAlias www.example.local
8. Save the file and restart Apache: service Apache2 restart

Open a browser and navigate to example.local. You should see your website.

You can use datetime module to help here. Also, as a side note, a simple date subtraction should work as below:

import datetime as dt
import numpy as np
import pandas as pd

Now, change type to datetime.timedelta, and then use the .days method on valid timedelta objects.

In [226]: df_test['Diffference'] = df_test['Difference'].astype(dt.timedelta).map(lambda x: np.nan if pd.isnull(x) else x.days)

In [227]: df_test

Custom String Values for Enum

from http://javahowto.blogspot.com/2006/10/custom-string-values-for-enum.html

The default string value for java enum is its face value, or the element name. However, you can customize the string value by overriding toString() method. For example,

public enum MyType {
  ONE {
      public String toString() {
          return "this is one";
      }
  },

  TWO {
      public String toString() {
          return "this is two";
      }
  }
}

Running the following test code will produce this:

public class EnumTest {
  public static void main(String[] args) {
      System.out.println(MyType.ONE);
      System.out.println(MyType.TWO);
  }
}


this is one
this is two

First, install the URL Rewrite from a download or from the Web Platform Installer. Second, restart IIS. And, finally, close IIS and open again. The last step worked for me.

There don't seem to be any perfect libraries or ways to do this yourself, unless you have to time to send an email to the email address and wait for a response (this might not be an option though). I ended up using a suggestion from here http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/ and adjusting the code so it would work in Java.

public static boolean isValidEmailAddress(String email) {
    boolean stricterFilter = true; 
    String stricterFilterString = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
    String laxString = ".+@.+\\.[A-Za-z]{2}[A-Za-z]*";
    String emailRegex = stricterFilter ? stricterFilterString : laxString;
    java.util.regex.Pattern p = java.util.regex.Pattern.compile(emailRegex);
    java.util.regex.Matcher m = p.matcher(email);
    return m.matches();
}

Floating div's will help what your trying to achieve.

Example

HTML

<div class="container">
<div class="content1 content">
</div>
<div class="content2 content">
</div>
</div>

CSS

.container{
width:100%;
height:200px;
background-color:grey;
}
.content{
float:left;
height:30px;
}
.content1{
background-color:blue;
width:300px;
}
.content2{
width:200px;
background-color:green;
}

Zoom in the page to see the effects.

Hope it helps.

Aergistal's answer works, but I found that converting to mp4 can make some m3u8 videos broken. If you are stuck with this problem, try to convert them to mkv, and convert them to mp4 later.

You can change the display resolution graphically (without using Terminal) on Raspbian GNU/Linux 8 (jessie) using following window.

Came across this question, while trying to uninstall the many random Python packages installed over time.

Using information from this thread, this is what I came up with:

cat package_list | xargs -n1 sudo pip uninstall -y

The package_list is cleaned up (awk) from a pip freeze in a virtualenv.

To remove almost all Python packages:

yolk -l | cut -f 1 -d " " | grep -v "setuptools|pip|ETC.." | xargs -n1 pip uninstall -y

One simple thing you could do is abstract the test inside a function.

local function isempty(s)
  return s == nil or s == ''
end

if isempty(foo) then
  foo = "default value"
end

Use sed's substitution: sed 's/"//g'

s/X/Y/ replaces X with Y.

g means all occurrences should be replaced, not just the first one.

When you're using GROUP BY, you need to also use aggregate functions for the columns not inside your group by clause.

I don't know exactly what you're trying to do, but I guess this would work:

select 
    LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000),
    PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
    qvalues.name,
    qvalues.compound,
    MAX(qvalues.rid)
from
    batchinfo join qvalues on batchinfo.rowid=qvalues.rowid
where
    LEN(datapath)>4
group by
    LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000),
    PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
    qvalues.name,
    qvalues.compound
having
    rid!=MAX(rid)

Edit: What I'm trying to do here is a group by with all fields but rid. If that's not what you want, what you need to do in order to have a valid SQL statement is adding an aggregate function call for each removed group by field...

Right now, I'm using twinsplay to organize my windows side by side.

I tried Winsplit before, but I couldn't get it to work because the default hotkeys ( Ctrl-Alt-Left, Ctrl-Alt-Right ) clashed with the graphics card hotkeys for rotating my screen and setting different hotkeys just didn't work. Twinsplay just worked for me out of the box.

Another nice thing about twinsplay is that it also allows me to save and restore windows "sessions" - so I can save my work environment ( eclipse, total commander, visual studio, msdn, outlook, firefox ) before turning off the computer at night and then quickly get back to it in the morning.

Put from before where, and order_by on last:

$this->db->select('*');
$this->db->from('courses');
$this->db->where('tennant_id',$tennant_id);
$this->db->order_by("UPPER(course_name)","desc");

Or try BINARY:

ORDER BY BINARY course_name DESC;

You should add manually on codeigniter for binary sorting.

And set "course_name" character column.

If sorting is used on a character type column, normally the sort is conducted in a case-insensitive fashion.

What type of structure data in courses table?

If you frustrated you can put into array and return using PHP:

Use natcasesort for order in "natural order": (Reference: http://php.net/manual/en/function.natcasesort.php)

Your array from database as example: $array_db = $result_from_db:

$final_result = natcasesort($array_db);

print_r($final_result);

I know this is a very old question, but I've been asked by someone else something similar.

I don't have TeraData, but can't you do the following?

SELECT employee_number,
       course_code,
       MAX(course_completion_date)                                     AS max_course_date,
       MAX(course_completion_date) OVER (PARTITION BY employee_number) AS max_date
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code

The GROUP BY now ensures one row per course per employee. This means that you just need a straight MAX() to get the max_course_date.

Before your GROUP BY was just giving one row per employee, and the MAX() OVER() was trying to give multiple results for that one row (one per course).

Instead, you now need the OVER() clause to get the MAX() for the employee as a whole. This is now legitimate because each individual row gets just one answer (as it is derived from a super-set, not a sub-set). Also, for the same reason, the OVER() clause now refers to a valid scalar value, as defined by the GROUP BY clause; employee_number.

Perhaps a short way of saying this would be that an aggregate with an OVER() clause must be a super-set of the GROUP BY, not a sub-set.

Create your query with a GROUP BY at the level that represents the rows you want, then specify OVER() clauses if you want to aggregate at a higher level.

I didn't find it in the previous answers, so, with Java 8 and streams:

Convert String[] to Integer[]:

Arrays.stream(stringArray).map(Integer::valueOf).toArray(Integer[]::new)

to improve @Luca Filosofi's accepted answer,

if needed, changing the beginning clause of this regex to be /([^>[\s]?\r\n]?) will also ingore the cases where the newline comes after a tag AND some whitespace, instead of just a tag immediately followed by a newline

Yes.You can try with some hidden params.

  $("#form").submit( function(eventObj) {
      $("<input />").attr("type", "hidden")
          .attr("name", "something")
          .attr("value", "something")
          .appendTo("#form");
      return true;
  });

The shift can be implement with data types (char, int and long int). The float and double data connot be shifted.

value= value >> steps  // Right shift, signed data.
value= value << steps  // Left shift, signed data.

Is there a way in which I can update the plot just by adding more point[s] to it...

There are a number of ways of animating data in matplotlib, depending on the version you have. Have you seen the matplotlib cookbook examples? Also, check out the more modern animation examples in the matplotlib documentation. Finally, the animation API defines a function FuncAnimation which animates a function in time. This function could just be the function you use to acquire your data.

Each method basically sets the data property of the object being drawn, so doesn't require clearing the screen or figure. The data property can simply be extended, so you can keep the previous points and just keep adding to your line (or image or whatever you are drawing).

Given that you say that your data arrival time is uncertain your best bet is probably just to do something like:

import matplotlib.pyplot as plt
import numpy

hl, = plt.plot([], [])

def update_line(hl, new_data):
    hl.set_xdata(numpy.append(hl.get_xdata(), new_data))
    hl.set_ydata(numpy.append(hl.get_ydata(), new_data))
    plt.draw()

Then when you receive data from the serial port just call update_line.

VB is not a language. VB is a program that hosts VBA, just as Office hosts VBA. VB is a set of App objects, just like Word and Excel have, and a forms package, just like in Office.

So you can only write VBA code in VB.

PS this info is on the INFO tab on the VB question page for VB.

From VBA Info

VBA 6, was shipped in 1998 and includes a myriad of licensed hosts, among them: Office 2000 - 2010, AutoCAD, PI Processbook, and the stand-alone Visual Basic 6.0

I have calculated the formula below to make the conversions dpi to dp and sp

Hi I would do something like this:

var id = 4; // inital number of rows plus one
function addRow(){
   // add a new tr with id 
   // increment id;
}

function deleteRow(id){
   $("#" + id).remove();
}

and i would have a table like this:

<table id = 'dsTable' >
      <tr id=1>
         <td> Relationship Type </td>
         <td> Date of Birth </td>
         <td> Gender </td>
      </tr>
      <tr id=2>
         <td> Spouse </td>
         <td> 1980-22-03 </td>
         <td> female </td>
         <td> <input type="button" id ="addDep" value="Add" onclick = "add()" </td>
         <td> <input type="button" id ="deleteDep" value="Delete" onclick = "deleteRow(2)"  </td>
      </tr>
       <tr id=3>
         <td> Child </td>
         <td> 2008-23-06 </td>
         <td> female </td>
         <td> <input type="button" id ="addDep" value="Add" onclick = "add()"</td>
         <td>  <input type="button" id ="deleteDep" value="Delete" onclick = "deleteRow(3)" </td>
      </tr>
   </table>

Also if you want you can make a loop to build up the table. So it will be easy to build the table. The same you can do with edit:)

I was having this problem on Rails 4.2 (with ruby 2.2.3) and had to edit the font-awesome _paths.scss partial to remove references to $fa-font-path and removing a leading forward slash. The following was broken:

@font-face {
  font-family: 'FontAwesome';
  src: font-url('#{$fa-font-path}/fontawesome-webfont.eot?v=#{$fa-version}');
  src: font-url('#{$fa-font-path}/fontawesome-webfont.eot?#iefix&v=#{$fa-version}') format('embedded-opentype'),
    font-url('#{$fa-font-path}/fontawesome-webfont.woff2?v=#{$fa-version}') format('woff2'),
    font-url('#{$fa-font-path}/fontawesome-webfont.woff?v=#{$fa-version}') format('woff'),
    font-url('#{$fa-font-path}/fontawesome-webfont.ttf?v=#{$fa-version}') format('truetype'),
    font-url('#{$fa-font-path}/fontawesome-webfont.svg?v=#{$fa-version}#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

And the following works:

@font-face {
  font-family: 'FontAwesome';
  src: font-url('fontawesome-webfont.eot?v=#{$fa-version}');
  src: font-url('fontawesome-webfont.eot?#iefix&v=#{$fa-version}') format('embedded-opentype'),
    font-url('fontawesome-webfont.woff2?v=#{$fa-version}') format('woff2'),
    font-url('fontawesome-webfont.woff?v=#{$fa-version}') format('woff'),
    font-url('fontawesome-webfont.ttf?v=#{$fa-version}') format('truetype'),
    font-url('fontawesome-webfont.svg?v=#{$fa-version}#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

An alternative would be to simply remove the forward slash following the interpolated $fa-font-path and then define $fa-font-path as an empty string or subdirectory with trailing forward slash (as needed).

Remember to recompile assets and restart your server as needed. For example, on a passenger setup:

prompt> rake assets:clean; rake assets:clobber
prompt> RAILS_ENV=production RAILS_GROUPS=assets rake assets:precompile
prompt> service passenger restart

Then reload your browser.

I recommend PowerGrep

I had to do an e-discovery project several years ago. I found that fisdstr had some limitations, most especially fisdstr would eventually fail

the script had to search across thousands of files using a couple of dozen search terms/phrases.

Cygwin's grep worked much better, it didn't choke often, but ultimately I went to PowerGrep because the graphical interface made it much easier to tell when and where it crashed, and also it was really easy to edit in all the conditionals and output that I wanted. Ultimately PowerGrep was the most reliable of the three.

What you need to do is to exchange the SSH keys for the user the script runs as. Have a look at this tutorial

After doing so, your scripts will run without the need for entering a password. But, for security's sake, you don't want to do this for root users!

instead of this:

style={{
  textDecoration: completed ? 'line-through' : 'none'
}}

you could try the following using short circuiting:

style={{
  textDecoration: completed && 'line-through'
}}

https://codeburst.io/javascript-short-circuit-conditionals-bbc13ac3e9eb

key bit of information from the link:

Short circuiting means that in JavaScript when we are evaluating an AND expression (&&), if the first operand is false, JavaScript will short-circuit and not even look at the second operand.

It's worth noting that this would return false if the first operand is false, so might have to consider how this would affect your style.

The other solutions might be more best practice, but thought it would be worth sharing.

As @bodi0 correctly said, it is not possible. You either have to extent Bootstrap's grid system (you can search and find various solutions, here is a 7-column example) or use nested rows e.g. http://bootply.com/dd50he9tGe.

In the case of nested rows you might not always get the exact result but a similar one

<div class="row">
    <div class="col-lg-5">
        <div class="row">
            <div class="col-lg-4">1.67 (close to 1.5)</div>
            <div class="col-lg-8">3.33 (close to 3.5)</div>
        </div>    
    </div>
    <div class="col-lg-7">
        <div class="row">
            <div class="col-lg-6">3.5</div>
            <div class="col-lg-6">3.5</div>
        </div>    
    </div>
</div>

I just want to use some simple vector math to explain the barycentric coordinates solution which Andreas had given, it will be way easier to understand.

1. Area A is defined as any vector given by s * v02 + t * v01, with condition s >= 0 and t >= 0. If any point inside the triangle v0, v1, v2, it must be inside Area A.

2. If further restrict s, and t belongs to [0, 1]. We get Area B which contains all vectors of s * v02 + t * v01, with condition s, t belongs to [0, 1]. It is worth to note that the low part of the Area B is the mirror of Triangle v0, v1, v2. The problem comes to if we can give certain condition of s, and t, to further excluding the low part of Area B.

3. Assume we give a value s, and t is changing in [0, 1]. In the following pic, point p is on the edge of v1v2. All the vectors of s * v02 + t * v01 which are along the dash line by simple vector sum. At v1v2 and dash line cross point p, we have:

(1-s)|v0v2| / |v0v2| = tp|v0v1| / |v0v1|

we get 1 - s = tp, then 1 = s + tp. If any t > tp, which 1 < s + t where is on the double dash line, the vector is outside the triangle, any t <= tp, which 1 >= s + t where is on single dash line, the vector is inside the triangle.

Then if we given any s in [0, 1], the corresponding t must meet 1 >= s + t, for the vector inside triangle.

So finally we get v = s * v02 + t * v01, v is inside triangle with condition s, t, s+t belongs to [0, 1]. Then translate to point, we have

p - p0 = s * (p1 - p0) + t * (p2 - p0), with s, t, s + t in [0, 1]

which is the same as Andreas' solution to solve equation system p = p0 + s * (p1 - p0) + t * (p2 - p0), with s, t, s + t belong to [0, 1].

Enumerable.SequenceEqual(FirstList.OrderBy(fElement => fElement), 
                         SecondList.OrderBy(sElement => sElement))

After looking around on Google for a long time, trying out several solutions, both CSS, JavaScript and JQuery, i found that most of them were using an Image as the button. Some of them were hard to use, but i did manage to piece together something that ended out working out for me.

The important parts for me was:

• The Browse button had to be a Button (not an image).
• The button had to have a hover effect (to make it look nice).
• The Width of both the Text and the button had to be easy to adjust.
• The solution had to work in IE8, FF, Chrome and Safari.

This is the solution i came up with. And hope it can be of use to others as well.

Change the width of .file_input_textbox to change the width of the textbox.

Change the width of both .file_input_div, .file_input_button and .file_input_button_hover to change the width of the button. You might need to tweak a bit on the positions also. I never figured out why...

To test this solution, make a new html file and paste the content into it.

<html>
<head>

<style type="text/css">

.file_input_textbox {height:25px;width:200px;float:left; }
.file_input_div     {position: relative;width:80px;height:26px;overflow: hidden; }
.file_input_button  {width: 80px;position:absolute;top:0px;
                     border:1px solid #F0F0EE;padding:2px 8px 2px 8px; font-weight:bold; height:25px; margin:0px; margin-right:5px; }
.file_input_button_hover{width:80px;position:absolute;top:0px;
                     border:1px solid #0A246A; background-color:#B2BBD0;padding:2px 8px 2px 8px; height:25px; margin:0px; font-weight:bold; margin-right:5px; }
.file_input_hidden  {font-size:45px;position:absolute;right:0px;top:0px;cursor:pointer;
                     opacity:0;filter:alpha(opacity=0);-ms-filter:"alpha(opacity=0)";-khtml-opacity:0;-moz-opacity:0; }
</style>
</head>
<body>
    <input type="text" id="fileName" class="file_input_textbox" readonly="readonly">
 <div class="file_input_div">
  <input id="fileInputButton" type="button" value="Browse" class="file_input_button" />
  <input type="file" class="file_input_hidden" 
      onchange="javascript: document.getElementById('fileName').value = this.value" 
      onmouseover="document.getElementById('fileInputButton').className='file_input_button_hover';"
      onmouseout="document.getElementById('fileInputButton').className='file_input_button';" />
</div>
</body>
</html>

You need to double up your single quotes as follows:

REPLACE(@strip, '''', '')

To search for files not ending with ".tmp" we use the following regex:

^(?!.*[.]tmp$).*$

Tested with the Regex Tester gives following result:

For any of the JSON parse, use the website http://json2csharp.com/ (easiest way) to convert your JSON into C# class to deserialize your JSON into C# object.

 public class JSONClass
 {
        public string name { get; set; }
        public string url { get; set; }
        public bool visibility { get; set; }
        public string idField { get; set; }
        public bool defaultEvents { get; set; }
        public string type { get; set; }        
 }

Then use the JavaScriptSerializer (from System.Web.Script.Serialization), in case you don't want any third party DLL like newtonsoft.

using (StreamReader r = new StreamReader("jsonfile.json"))
{
   string json = r.ReadToEnd();
   JavaScriptSerializer jss = new JavaScriptSerializer();
   var Items = jss.Deserialize<JSONClass>(json);
}

Then you can get your object with Items.name or Items.Url etc.

Since it took me a while to figure it out, I thought it would be helpful to post my solution using Java 7+ ZipFileSystem

 openZip(runFile);

 addToZip(filepath); //loop construct;  

 zipfs.close();

 private void openZip(File runFile) throws IOException {
    Map<String, String> env = new HashMap<>();
    env.put("create", "true");
    env.put("encoding", "UTF-8");
    Files.deleteIfExists(runFile.toPath());
    zipfs = FileSystems.newFileSystem(URI.create("jar:" + runFile.toURI().toString()), env);    
 }

 private void addToZip(String filename) throws IOException {
    Path externalTxtFile = Paths.get(filename).toAbsolutePath();
    Path pathInZipfile = zipfs.getPath(filename.substring(filename.lastIndexOf("results"))); //all files to be stored have a common base folder, results/ in my case
    if (Files.isDirectory(externalTxtFile)) {
        Files.createDirectories(pathInZipfile);
        try (DirectoryStream<Path> ds = Files.newDirectoryStream(externalTxtFile)) {
            for (Path child : ds) {
                addToZip(child.normalize().toString()); //recursive call
            }
        }
    } else {
        // copy file to zip file
        Files.copy(externalTxtFile, pathInZipfile, StandardCopyOption.REPLACE_EXISTING);            
    }
 }

No, there isn't a boolean type in Oracle Database, but you can do this way:

You can put a check constraint on a column.

If your table hasn't a check column, you can add it:

ALTER TABLE table_name
ADD column_name_check char(1) DEFAULT '1';

When you add a register, by default this column get 1.

Here you put a check that limit the column value, just only put 1 or 0

ALTER TABLE table_name ADD
CONSTRAINT name_constraint 
column_name_check (ONOFF in ( '1', '0' ));

You can either use an if statement to check if the directory exists or not. If it does not exits, then create the directory.

1. dir=/home/dir_name

   if [ ! -d $dir ]
   then
        mkdir $dir
   else
        echo "Directory exists"
   fi
   

2. You can directory use mkdir with -p option to create a directory. It will check if the directory is not available it will.

   mkdir -p $dir
   

   mkdir -p also allows to create the tree structure of the directory. If you want to create the parent and child directories using same command, can opt mkdir -p

   mkdir -p /home/parent_dir /home/parent_dir/child1 /home/parent_dir/child2
   

Two Method

• using homebrew auto install:
  • Steps:
    • brew install gradle
  • Pros and cons
    • Pros: easy
    • Cons: (probably) not latest version
• manually install (for latest version):
  • Pros and cons
    • Pros: use your expected any (or latest) version
    • Cons: need self to do it
  • Steps
    • download latest version binary (gradle-6.0.1) from Gradle | Releases
    • unzip it (gradle-6.0.1-all.zip) and added gradle path into environment variable PATH
      • normally is edit and add following config into your startup script( ~/.bashrc or ~/.zshrc etc.):

export GRADLE_HOME=/path_to_your_gradle/gradle-6.0.1
export PATH=$GRADLE_HOME/bin:$PATH

some other basic note

Q: How to make PATH take effect immediately?

A: use source:

source ~/.bashrc

it will make/execute your .bashrc, so make PATH become your expected latest values, which include your added gradle path.

Q: How to check PATH is really take effect/working now?

A: use echo to see your added path in indeed in your PATH

?  ~ echo $PATH
xxx:/Users/crifan/dev/dev_tool/java/gradle/gradle-6.0.1/bin:xxx

you can see we added /Users/crifan/dev/dev_tool/java/gradle/gradle-6.0.1/bin into your PATH

Q: How to verify gradle is installed correctly on my Mac ?

A: use which to make sure can find gradle

?  ~ which gradle
/Users/crifan/dev/dev_tool/java/gradle/gradle-6.0.1/bin/gradle

AND to check and see gradle version

?  ~ gradle --version

You can also do it the following way:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
 $(document).ready(function(){
     $("#hide").click(function(){
     $("#test").hide();
     });
     $("#show").click(function(){
     $("#test").show();
     });
 });
</script>
</head>

<body>
<h2>This is a test of jQuery!</h2>
<p id="test">This is a hidden paragraph.</p>
<button id="hide">Click me to hide</button>
<button id="show">Click me to show</button>
</body>

the previous answers showed using multiple named functions inside a single .ready block, or a single unnamed function in the .ready block, with another named function outside the .ready block. I found this question while researching if there was a way to have multiple unnamed functions inside the .ready block - I could not get the syntax correct. I finally figured it out, and hoped that by posting my test code I would help others looking for the answer to the same question I had

Most probly sun's administrative server.. It's usually bundled along with sun's directory and a few other webmin-ish stuff that is in the default installation

if you want to rotate inline elements, you should set the inline element to inline-block first.

i {
  display: inline-block;
}

i:hover {
  animation: rotate-btn .5s linear 3;
  -webkit-animation: rotate-btn .5s linear 3;
}

@keyframes rotate-btn {
  0% {
    transform: rotate(0);
  }
  100% {
    transform: rotate(-360deg);
  }
}

This is straight from Bjarne Stroustrup's page:

If you so choose, you can still shoot yourself in the foot by inheriting constructors in a derived class in which you define new member variables needing initialization:

struct B1 {
    B1(int) { }
};

struct D1 : B1 {
    using B1::B1; // implicitly declares D1(int)
    int x;
};

void test()
{
    D1 d(6);    // Oops: d.x is not initialized
    D1 e;       // error: D1 has no default constructor
}

If the string should be of fixed length, then substr from base R can be used. But, we can get the position of the . with regexpr and use that in substr

substr(a, 1, regexpr("\\.", a)-1)
#[1] "NM_020506"    "NM_020519"    "NM_001030297" "NM_010281"    "NM_011419"    "NM_053155"   

It appears that you are using the default route which is defined as this:

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

The key part of that route is the {id} piece. If you look at your action method, your parameter is k instead of id. You need to change your action method to this so that it matches the route parameter:

// change int k to int id
public ActionResult DetailsData(int id)

If you wanted to leave your parameter as k, then you would change the URL to be:

http://localhost:7317/Employee/DetailsData?k=4

You also appear to have a problem with your connection string. In your web.config, you need to change your connection string to this (provided by haim770 in another answer that he deleted):

<connectionStrings>
  <add name="EmployeeContext"
       connectionString="Server=.;Database=mytry;integrated security=True;"
       providerName="System.Data.SqlClient" />
</connectionStrings>

set up a new postgresql server and replace its data folder with the files from your external disk.

You will then be able to start that postgresql server up and retrieve the data using pg_dump (pg_dump -s for the schema-only as mentioned)

You could maybe add

.print:last-child {
     page-break-after: auto;
}

so the last print element will not get the extra page break.

Do note that the :last-child selector is not supported in IE8, if you're targetting that wretch of a browser.

Yes, they are very different in theory, and in implementation.

Lexers are used to recognize "words" that make up language elements, because the structure of such words is generally simple. Regular expressions are extremely good at handling this simpler structure, and there are very high-performance regular-expression matching engines used to implement lexers.

Parsers are used to recognize "structure" of a language phrases. Such structure is generally far beyond what "regular expressions" can recognize, so one needs "context sensitive" parsers to extract such structure. Context-sensitive parsers are hard to build, so the engineering compromise is to use "context-free" grammars and add hacks to the parsers ("symbol tables", etc.) to handle the context-sensitive part.

Neither lexing nor parsing technology is likely to go away soon.

They may be unified by deciding to use "parsing" technology to recognize "words", as is currently explored by so-called scannerless GLR parsers. That has a runtime cost, as you are applying more general machinery to what is often a problem that doesn't need it, and usually you pay for that in overhead. Where you have lots of free cycles, that overhead may not matter. If you process a lot of text, then the overhead does matter and classical regular expression parsers will continue to be used.

You can use T-SQL to convert the date before it gets to your .NET program. This often is simpler if you don't need to do additional date conversion in your .NET program.

DECLARE @Date DATETIME = Getdate()
DECLARE @DateInt INT = CONVERT(VARCHAR(30), @Date, 112)
DECLARE @TimeInt INT = REPLACE(CONVERT(VARCHAR(30), @Date, 108), ':', '')
DECLARE @DateTimeInt BIGINT = CONVERT(VARCHAR(30), @Date, 112) + REPLACE(CONVERT(VARCHAR(30), @Date, 108), ':', '')
SELECT @Date as Date, @DateInt DateInt, @TimeInt TimeInt, @DateTimeInt DateTimeInt

Date                    DateInt     TimeInt     DateTimeInt

You can use something like this:

RewriteEngine on
RewriteRule ^.+$ /index.php [L]

This will redirect every query to the root directory's index.php. Note that it will also redirect queries for files that exist, such as images, javascript files or style sheets.

Since the OP was asking for using a custom compare function (and this is what led me to this question as well), I want to give a solid answer here:

Generally, you want to use the built-in sorted() function which takes a custom comparator as its parameter. We need to pay attention to the fact that in Python 3 the parameter name and semantics have changed.

How the custom comparator works

When providing a custom comparator, it should generally return an integer/float value that follows the following pattern (as with most other programming languages and frameworks):

• return a negative value (< 0) when the left item should be sorted before the right item
• return a positive value (> 0) when the left item should be sorted after the right item
• return 0 when both the left and the right item have the same weight and should be ordered "equally" without precedence

In the particular case of the OP's question, the following custom compare function can be used:

def compare(item1, item2):
    return fitness(item1) - fitness(item2)

Using the minus operation is a nifty trick because it yields to positive values when the weight of left item1 is bigger than the weight of the right item2. Hence item1 will be sorted after item2.

If you want to reverse the sort order, simply reverse the subtraction: return fitness(item2) - fitness(item1)

Calling sorted() in Python 2

sorted(mylist, cmp=compare)

or:

sorted(mylist, cmp=lambda item1, item2: fitness(item1) - fitness(item2))

Calling sorted() in Python 3

from functools import cmp_to_key
sorted(mylist, key=cmp_to_key(compare))

or:

from functools import cmp_to_key
sorted(mylist, key=cmp_to_key(lambda item1, item2: fitness(item1) - fitness(item2)))

select the index then select the ones needed then select sql and click action then click rebuild

The first constructor in the header should not end with a semicolon. #include <string> is missing in the header. string is not qualified with std:: in the .cpp file. Those are all simple syntax errors. More importantly: you are not using references, when you should. Also the way you use the ifstream is broken. I suggest learning C++ before trying to use it.

Let's fix this up:

//polygone.h
# if !defined(__POLYGONE_H__)
# define __POLYGONE_H__

#include <iostream>
#include <string>    

class Polygone {
public:
  // declarations have to end with a semicolon, definitions do not
  Polygone(){} // why would we needs this?
  Polygone(const std::string& fichier);
};

# endif

and

//polygone.cc
// no need to include things twice
#include "polygone.h"
#include <fstream>


Polygone::Polygone(const std::string& nom)
{
  std::ifstream fichier (nom, ios::in);


  if (fichier.is_open())
  {
    // keep the scope as tiny as possible
    std::string line;
    // getline returns the stream and streams convert to booleans
    while ( std::getline(fichier, line) )
    {
      std::cout << line << std::endl;
    }
  }
  else
  {
    std::cerr << "Erreur a l'ouverture du fichier" << std::endl;
  }
}

boost::lexical_cast works pretty well.

#include <boost/lexical_cast.hpp>
int main(int argc, char** argv) {
    std::string foo = boost::lexical_cast<std::string>(argc);
}

Read about Storage Engines.

MyISAM:

The MyISAM storage engine in MySQL.

• Simpler to design and create, thus better for beginners. No worries about the foreign relationships between tables.
• Faster than InnoDB on the whole as a result of the simpler structure thus much less costs of server resources. -- Mostly no longer true.
• Full-text indexing. -- InnoDB has it now
• Especially good for read-intensive (select) tables. -- Mostly no longer true.
• Disk footprint is 2x-3x less than InnoDB's. -- As of Version 5.7, this is perhaps the only real advantage of MyISAM.

InnoDB:

The InnoDB storage engine in MySQL.

• Support for transactions (giving you support for the ACID property).
• Row-level locking. Having a more fine grained locking-mechanism gives you higher concurrency compared to, for instance, MyISAM.
• Foreign key constraints. Allowing you to let the database ensure the integrity of the state of the database, and the relationships between tables.
• InnoDB is more resistant to table corruption than MyISAM.
• Support for large buffer pool for both data and indexes. MyISAM key buffer is only for indexes.
• MyISAM is stagnant; all future enhancements will be in InnoDB. This was made abundantly clear with the roll out of Version 8.0.

MyISAM Limitations:

• No foreign keys and cascading deletes/updates
• No transactional integrity (ACID compliance)
• No rollback abilities
• 4,284,867,296 row limit (2^32) -- This is old default. The configurable limit (for many versions) has been 2**56 bytes.
• Maximum of 64 indexes per table

InnoDB Limitations:

• No full text indexing (Below-5.6 mysql version)
• Cannot be compressed for fast, read-only (5.5.14 introduced ROW_FORMAT=COMPRESSED)
• You cannot repair an InnoDB table

For brief understanding read below links:

Remove the * from your query and use individual column names, like this:

SELECT SOME_OTHER_COLUMN, CONCAT(FIRSTNAME, ',', LASTNAME) AS FIRSTNAME FROM `customer`;

Using * means, in your results you want all the columns of the table. In your case * will also include FIRSTNAME. You are then concatenating some columns and using alias of FIRSTNAME. This creates 2 columns with same name.

If you are debugging your CSS using Print As PDF in Google Chrome and your CSS element background colors are not showing, then make sure the 'Background graphics' checkbox is ticked. I spent almost 30 minutes debugging my CSS and wondering what is causing my CSS background being ignored.

Just type .htaccess. as filename. Notice the dot at the end of htaccess. This will change in Windows to .htaccess without a dot at the end.

Here is a unique way of setting Authorization token in axios. Setting configuration to every axios call is not a good idea and you can change the default Authorization token by:

import axios from 'axios';
axios.defaults.baseURL = 'http://localhost:1010/'
axios.defaults.headers.common = {'Authorization': `bearer ${token}`}
export default axios;

Edit, Thanks to Jason Norwood-Young.

Some API require bearer to be written as Bearer, so you can do:

axios.defaults.headers.common = {'Authorization': `Bearer ${token}`}

Now you don't need to set configuration to every API call. Now Authorization token is set to every axios call.

Put your domain name here: https://www.ssllabs.com/ssltest/analyze.html You should be able to see if there are any issues with your ssl certificate chain. I am guessing that you have SSL chain issues. A short description of the problem is that there's actually a list of certificates on your server (and not only one) and these need to be in the correct order. If they are there but not in the correct order, the website will be fine on desktop browsers (an iOs as well I think), but android is more strict about the order of certificates, and will give an error if the order is incorrect. To fix this you just need to re-order the certificates.

You can also use animationListener, something like this:

fadeIn.setAnimationListener(new AnimationListener() {
    @Override
    public void onAnimationEnd(Animation animation) {
        this.startAnimation(fadeout);
    }
});

Markdown gets converted into HTML/XHMTL.

John Gruber created the Markdown language in 2004 in collaboration with Aaron Swartz on the syntax, with the goal of enabling people to write using an easy-to-read, easy-to-write plain text format, and optionally convert it to structurally valid HTML (or XHTML).

HTML is completely based on using   for adding extra spaces if it doesn't externally define/use JavaScript or CSS for elements.

Markdown is a lightweight markup language with plain text formatting syntax. It is designed so that it can be converted to HTML and many other formats using a tool by the same name.

If you want to use »

1. only one space » either use   or just hit Spacebar (2nd one is good choice in this case)

2. more than one space » use  +space (for 2 consecutive spaces)

eg. If you want to add 10 spaces contiguously then you should use

                   

 space space space space space

instead of using 10   one after one as the below one

          

For more details check

2. How to create extra space in HTML or web page.

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.

Real world examples

To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency or UIViewRoot#addComponentResource()) the following way:

<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />

It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.

Easier identifying

This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.

Also, when you're using a custom ResourceHandler, you can also apply more finer grained control over resources coming from a specific library when library is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler and GraphicResourceHandler; check the createResource() method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource or GraphicResource for the purpose.

Noted should be that RichFaces did it wrong. It didn't use any library at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.

Your own webapp

Your own webapp does not necessarily need a resource library. You'd best just omit it.

<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />

Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml template file:

<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />

And a /WEB-INF/templates/admin.xhtml template file:

<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />

For a real world example, check the OmniFaces showcase source code.

Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):

<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />

Library versioning

Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)* pattern to denote the resource library version.

WebContent
 |-- resources
 |    `-- default
 |         `-- 1_0
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

When using this markup:

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

This will generate the following HTML with the library version as v parameter:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_0" alt="" />

So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler will automatically serve the resource from the highest version number, according to numerical ordering rules.

So, when copying/renaming resources/default/1_0/* folder into resources/default/1_1/* like follows:

WebContent
 |-- resources
 |    `-- default
 |         |-- 1_0
 |         |    :
 |         |
 |         `-- 1_1
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

Then the last markup example would generate the following HTML:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_1" alt="" />

This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.

Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler. See also How to use JSF versioning for resources in jar.

Please, take a look at implementation of the copytree function which:

• List directory files with:

  names = os.listdir(src)

• Copy files with:

for name in names:
  srcname = os.path.join(src, name)
  dstname = os.path.join(dst, name)
  copy2(srcname, dstname)

Getting dstname is not necessary, because if destination parameter specifies a directory, the file will be copied into dst using the base filename from srcname.

Replace copy2 by move.

The only thing which works with no side-effects is to create a custom back button. As long as you don't provide a custom action, even the slide gesture works.

extension UIViewController {
func setupBackButton() {
    let customBackButton = UIBarButtonItem(title: " ", style: .plain, target: nil, action: nil)
    navigationItem.backBarButtonItem = customBackButton
}}

Unfortunately, if you want all back buttons in the not to have any titles, you need to setup this custom back button in all your view controllers :/

override func viewDidLoad() {
    super.viewDidLoad()

    setupBackButton()
}

It is very important you set a whitespace as the title and not the empty string.

You're trying to insert $newdate into your db. You need to convert it to a string first. Use the DateTime::format method to convert back to a string.

By default - No.

There's the length property that is commonly used for the same result in the following way:

if ($(selector).length)

Here, 'selector' is to be replaced by the actual selector you are interested to find if it exists or not. If it does exist, the length property will output an integer more than 0 and hence the if statement will become true and hence execute the if block. If it doesn't, it will output the integer '0' and hence the if block won't get executed.

Update for Java 8 and higher

You can now simply do Instant.parse("2015-04-28T14:23:38.521Z") and get the correct thing now, especially since you should be using Instant instead of the broken java.util.Date with the most recent versions of Java.

You should be using DateTimeFormatter instead of SimpleDateFormatter as well.

Original Answer:

The explanation below is still valid as as what the format represents. But it was written before Java 8 was ubiquitous so it uses the old classes that you should not be using if you are using Java 8 or higher.

This works with the input with the trailing Z as demonstrated:

In the pattern the T is escaped with ' on either side.

The pattern for the Z at the end is actually XXX as documented in the JavaDoc for SimpleDateFormat, it is just not very clear on actually how to use it since Z is the marker for the old TimeZone information as well.

Based on Teste's code .. I can confirm the following works. I can't say whether or not this is "good" code, but it certainly works and could get you back up and running quickly if you ended up with GCM to FCM server problems!

I would like to add one more reliable way using UsedRange to find the last used row:

lastRow = Sheet1.UsedRange.Row + Sheet1.UsedRange.Rows.Count - 1

Similarly to find the last used column you can see this

Result in Immediate Window:

?Sheet1.UsedRange.Row+Sheet1.UsedRange.Rows.Count-1
 21 

In Linux and Mac there are not default shortcuts, so try to set your custom shortcut and be careful about don't choose a hotkey used (For example, CTRL+U is taken for uncomment)

1. File-> Preferences -> Keyboard Shortcuts.
2. Type 'transfrom' in the search input to find transform shortcuts.
3. Edit your key combination.

In my case I have CTRL+U CTRL+U for transform to uppercase and CTRL+L CTRL+L for transform to lowercase

Just in case, for Mac instead of CTRL I used ?

In C, single-quotes such as 'a' indicate character constants whereas "a" is an array of characters, always terminated with the \0 character

The hidden input solution wasn't working for me in Safari. The solution below works, and came from here.

window.onpageshow = function(event) {
if (event.persisted) {
    window.location.reload() 
}
};

You already have the solution in the question -- the only way is to iterate the whole table with pairs(..).

function tablelength(T)
  local count = 0
  for _ in pairs(T) do count = count + 1 end
  return count
end

Also, notice that the "#" operator's definition is a bit more complicated than that. Let me illustrate that by taking this table:

t = {1,2,3}
t[5] = 1
t[9] = 1

According to the manual, any of 3, 5 and 9 are valid results for #t. The only sane way to use it is with arrays of one contiguous part without nil values.

Boost.Regex is very good and is slated to become part of the C++0x standard (it's already in TR1).

Personally, I find Boost.Xpressive much nicer to work with. It is a header-only library and it has some nice features such as static regexes (regexes compiled at compile time).

Update: If you're using a C++11 compliant compiler (gcc 4.8 is NOT!), use std::regex unless you have good reason to use something else.

You CAN use UTF-8 in the POST request, all you need is to specify the charset in your request.

You should use this request:

curl -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=utf-8" --data-ascii "content=derinhält&date=asdf" http://myserverurl.com/api/v1/somemethod

This can be done as follows :

select CONVERT(VARCHAR(10), GETDATE(), 103) + ' '  + convert(VARCHAR(8), GETDATE(), 14)

Hope it helps

First off, I will second the nomination of python's logging framework. Be a little careful about how you use it, however. Specifically: let the logging framework expand your variables, don't do it yourself. For instance, instead of:

logging.debug("datastructure: %r" % complex_dict_structure)

make sure you do:

logging.debug("datastructure: %r", complex_dict_structure)

because while they look similar, the first version incurs the repr() cost even if it's disabled. The second version avoid this. Similarly, if you roll your own, I'd suggest something like:

def debug_stdout(sfunc):
    print(sfunc())

debug = debug_stdout

called via:

debug(lambda: "datastructure: %r" % complex_dict_structure)

which will, again, avoid the overhead if you disable it by doing:

def debug_noop(*args, **kwargs):
    pass

debug = debug_noop

The overhead of computing those strings probably doesn't matter unless they're either 1) expensive to compute or 2) the debug statement is in the middle of, say, an n^3 loop or something. Not that I would know anything about that.

public void EndTask(string taskname)
{
      string processName = taskname.Replace(".exe", "");

      foreach (Process process in Process.GetProcessesByName(processName))
      {
          process.Kill();
      }
}

//EndTask("notepad");

Summary: no matter if the name contains .exe, the process will end. You don't need to "leave off .exe from process name", It works 100%.

If you're using Hive 11 or better you can use the INSERT statement with the LOCAL keyword.

Example:

insert overwrite local directory '/home/carter/staging' row format delimited fields terminated by ',' select * from hugetable;

Note that this may create multiple files and you may want to concatenate them on the client side after it's done exporting.

Using this approach means you don't need to worry about the format of the source tables, can export based on arbitrary SQL query, and can select your own delimiters and output formats.

In regards Jared's response, having Windows 2000 or better will not necessarily fix the issue at hand. Rob's response does work, however it is possible that this fix introduces security issues, as Windows updates will not be able to patch applications built as such.

In another post, Nick Guerrera suggests packaging the Visual C++ Runtime Redistributable with your applications, which installs quickly, and is independent of Visual Studio.

How to reproduce the above error in PHP:

php> $yarr = array(3 => 'c', 4 => 'd');

php> echo $yarr[4];
d

php> echo $yarr[1];
PHP Notice:  Undefined offset: 1 in 
/usr/local/lib/python2.7/dist-packages/phpsh/phpsh.php(578) : 
eval()'d code on line 1

What does that error message mean?

It means the php compiler looked for the key 1 and ran the hash against it and didn't find any value associated with it then said Undefined offset: 1

How do I make that error go away?

Ask the array if the key exists before returning its value like this:

php> echo array_key_exists(1, $yarr);

php> echo array_key_exists(4, $yarr);
1

If the array does not contain your key, don't ask for its value. Although this solution makes double-work for your program to "check if it's there" and then "go get it".

Alternative solution that's faster:

If getting a missing key is an exceptional circumstance caused by an error, it's faster to just get the value (as in echo $yarr[1];), and catch that offset error and handle it like this: https://stackoverflow.com/a/5373824/445131

Try the below JS

$(function() {
    $('#type').change(function(){
        $('#row_dim').hide(); 
        if ($(this).val() == 'parcel')
        {
             $('#row_dim').show();
        }
    });
});

With the other answers, the person reading the answer must be aware of the vehicle table and create the vehicle table and data to test a solution.

Below is an example that uses SQL Server "Information_Schema.Columns" table. By using this solution, no tables need to be created or data added. This example creates a comma separated list of column names for all tables in the database.

SELECT
    Table_Name
    ,STUFF((
        SELECT ',' + Column_Name
        FROM INFORMATION_SCHEMA.Columns Columns
        WHERE Tables.Table_Name = Columns.Table_Name
        ORDER BY Column_Name
        FOR XML PATH ('')), 1, 1, ''
    )Columns
FROM INFORMATION_SCHEMA.Columns Tables
GROUP BY TABLE_NAME 

I have found a slightly different way implement pointers that is perhaps more general and easier to understand from a C perspective (and thus fits more into the format of the users example).

In JavaScript, like in C, array variables are actually just pointers to the array, so you can use an array as exactly the same as declaring a pointer. This way, all pointers in your code can be used the same way, despite what you named the variable in the original object.

It also allows one to use two different notations referring to the address of the pointer and what is at the address of the pointer.

Here is an example (I use the underscore to denote a pointer):

var _x = [ 10 ];

function foo(_a){
    _a[0] += 10;
}

foo(_x);

console.log(_x[0]);

Yields

output: 20

You are trying to compare strings inside an arithmetic command (((...))). Use [[ instead.

if [[ $username == "$username1" && $password == "$password1" ]] ||
   [[ $username == "$username2" && $password == "$password2" ]]; then

Note that I've reduced this to two separate tests joined by ||, with the && moved inside the tests. This is because the shell operators && and || have equal precedence and are simply evaluated from left to right. As a result, it's not generally true that a && b || c && d is equivalent to the intended ( a && b ) || ( c && d ).

window.open(url, wndname, params), it has three arguments. if you don't want it open in the same window, just set a different wndname. such as :

window.open(url1, "name1", params); // this open one window or tab
window.open(url1, "name2", params); // though url is same, but it'll open in another window(tab).

Here is the details about window.open(), you can trust it!

I use this handy function:

By downloading it with a 4094 byte step it will not full your memory

function download($file_source, $file_target) {
    $rh = fopen($file_source, 'rb');
    $wh = fopen($file_target, 'w+b');
    if (!$rh || !$wh) {
        return false;
    }

    while (!feof($rh)) {
        if (fwrite($wh, fread($rh, 4096)) === FALSE) {
            return false;
        }
        echo ' ';
        flush();
    }

    fclose($rh);
    fclose($wh);

    return true;
}

Usage:

     $result = download('http://url','path/local/file');

You can then check if everything is ok with:

     if (!$result)

You technically have two options when speaking of ISO dates.

In general, if you're filtering specifically on Date values alone OR looking to persist date in a neutral fashion. Microsoft recommends using the language neutral format of ymd or y-m-d. Which are both valid ISO formats.

Note that the form '2007-02-12' is considered language-neutral only for the data types DATE, DATETIME2, and DATETIMEOFFSET.

Because of this, your safest bet is to persist/filter based on the always netural ymd format.

The code:

select convert(char(10), getdate(), 126) -- ISO YYYY-MM-DD
select convert(char(8), getdate(), 112) -- ISO YYYYMMDD (safest)

An entity manager can only be injected in classes running inside a transaction. In other words, it can only be injected in a EJB. Other classe must use an EntityManagerFactory to create and destroy an EntityManager.

Since your TestService is not an EJB, the annotation @PersistenceContext is simply ignored. Not only that, in JavaEE 5, it's not possible to inject an EntityManager nor an EntityManagerFactory in a JAX-RS Service. You have to go with a JavaEE 6 server (JBoss 6, Glassfish 3, etc).

Here's an example of injecting an EntityManagerFactory:

package com.test.service;

import java.util.*;
import javax.persistence.*;
import javax.ws.rs.*;

@Path("/service")
public class TestService {

    @PersistenceUnit(unitName = "test")
    private EntityManagerFactory entityManagerFactory;

    @GET
    @Path("/get")
    @Produces("application/json")
    public List get() {
        EntityManager entityManager = entityManagerFactory.createEntityManager();
        try {
            return entityManager.createQuery("from TestEntity").getResultList();
        } finally {
            entityManager.close();
        }
    }
}

The easiest way to go here is to declare your service as a EJB 3.1, assuming you're using a JavaEE 6 server.

This below query worked for me. This can able to show the databases,tables,column names,data types and columns count.

**select table_schema Schema_Name ,table_name TableName,column_name ColumnName,ordinal_position "Position",column_type DataType,COUNT(1) ColumnCount
FROM information_schema.columns
GROUP by table_schema,table_name,column_name,ordinal_position, column_type;**

You have to correctly override method equals() from class Object

Edit: I think that my first response was misunderstood probably because I was not too precise. So I decided to to add more explanations.

Why do you have to override equals()? Well, because this is in the domain of a developer to decide what does it mean for two objects to be equal. Reference equality is not enough for most of the cases.

For example, imagine that you have a HashMap whose keys are of type Person. Each person has name and address. Now, you want to find detailed bean using the key. The problem is, that you usually are not able to create an instance with the same reference as the one in the map. What you do is to create another instance of class Person. Clearly, operator == will not work here and you have to use equals().

But now, we come to another problem. Let's imagine that your collection is very large and you want to execute a search. The naive implementation would compare your key object with every instance in a map using equals(). That, however, would be very expansive. And here comes the hashCode(). As others pointed out, hashcode is a single number that does not have to be unique. The important requirement is that whenever equals() gives true for two objects, hashCode() must return the same value for both of them. The inverse implication does not hold, which is a good thing, because hashcode separates our keys into kind of buckets. We have a small number of instances of class Person in a single bucket. When we execute a search, the algorithm can jump right away to a correct bucket and only now execute equals for each instance. The implementation for hashCode() therefore must distribute objects as evenly as possible across buckets.

There is one more point. Some collections require a proper implementation of a hashCode() method in classes that are used as keys not only for performance reasons. The examples are: HashSet and LinkedHashSet. If they don’t override hashCode(), the default Object hashCode() method will allow multiple objects that you might consider "meaningfully equal" to be added to your "no duplicates allowed" set.

Some of the collections that use hashCode()

• HashSet
• LinkedHashSet
• HashMap

Have a look at those two classes from apache commons that will allow you to implement equals() and hashCode() easily

• EqualsBuilder
• HashCodeBuilder

Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

Edit: Here's a working ultra-minimalistic file sender and receiver. Make sure you understand what the code is doing on both sides.

To update and answer the question without breaking mail servers. Later versions of CentOS 7 have MariaDB included as the base along with PostFix which relies on MariaDB. Removing using yum will also remove postfix and perl-DBD-MySQL. To get around this and keep postfix in place, first make a copy of /usr/lib64/libmysqlclient.so.18 (which is what postfix depends on) and then use:

rpm -qa | grep mariadb

then remove the mariadb packages using (changing to your versions):

rpm -e --nodeps "mariadb-libs-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-server-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-5.5.56-2.el7.x86_64"

Delete left over files and folders (which also removes any databases):

rm -f /var/log/mariadb
rm -f /var/log/mariadb/mariadb.log.rpmsave
rm -rf /var/lib/mysql
rm -rf /usr/lib64/mysql
rm -rf /usr/share/mysql

Put back the copy of /usr/lib64/libmysqlclient.so.18 you made at the start and you can restart postfix.

There is more detail at https://code.trev.id.au/centos-7-remove-mariadb-replace-mysql/ which describes how to replace mariaDB with MySQL

Extract single value from JSON response Python

Try this

import json
import sys

#load the data into an element
data={"test1" : "1", "test2" : "2", "test3" : "3"}

#dumps the json object into an element
json_str = json.dumps(data)

#load the json to a string
resp = json.loads(json_str)

#print the resp
print (resp)

#extract an element in the response
print (resp['test1'])

In Recycler Layout manager the second parameter is spanCount increase or decrease in span count will change number of elements show on your screen

                recyclerView.setLayoutManager(mLayoutManager);

Fot people who have tried EVERYTHING and just CANNOT get the error details to show, like me, it's a good idea to check the different levels of configuration. I have a config file on Website level and on Application level (inside the website) check both. Also, as it turned out, I had Detailed Errors disabled on the highest node in IIS (just underneath Start Page, it has the name that is the same as the webservers computername). Check the Error Pages there.

The JVM abstracts from the concrete platform. Your program relies only upon the JVM and since the JVM is available for different platforms like Windows and Linux, your program is platform independent (but jvm depended).

Not really great but a funny hack: You can -- instead of +

{{num_str -- 1 }}

For larger numbers we may want to print in a more readable format. The example below does same as other but also prints in "human" format:

secs_to_human() {
    if [[ -z ${1} || ${1} -lt 60 ]] ;then
        min=0 ; secs="${1}"
    else
        time_mins=$(echo "scale=2; ${1}/60" | bc)
        min=$(echo ${time_mins} | cut -d'.' -f1)
        secs="0.$(echo ${time_mins} | cut -d'.' -f2)"
        secs=$(echo ${secs}*60|bc|awk '{print int($1+0.5)}')
    fi
    echo "Time Elapsed : ${min} minutes and ${secs} seconds."
}

Simple testing:

secs_to_human "300"
secs_to_human "305"
secs_to_human "59"
secs_to_human "60"
secs_to_human "660"
secs_to_human "3000"

Output:

Time Elapsed : 5 minutes and 0 seconds.
Time Elapsed : 5 minutes and 5 seconds.
Time Elapsed : 0 minutes and 59 seconds.
Time Elapsed : 1 minutes and 0 seconds.
Time Elapsed : 11 minutes and 0 seconds.
Time Elapsed : 50 minutes and 0 seconds.

To use in a script as described in other posts (capture start point then call the function with the finish time:

start=$(date +%s)
# << performs some task here >>
secs_to_human "$(($(date +%s) - ${start}))"

df['y'] will set a column

since you want to set a row, use .loc

Note that .ix is equivalent here, yours failed because you tried to assign a dictionary to each element of the row y probably not what you want; converting to a Series tells pandas that you want to align the input (for example you then don't have to to specify all of the elements)

In [7]: df = pandas.DataFrame(columns=['a','b','c','d'], index=['x','y','z'])

In [8]: df.loc['y'] = pandas.Series({'a':1, 'b':5, 'c':2, 'd':3})

In [9]: df
Out[9]: 
     a    b    c    d
x  NaN  NaN  NaN  NaN
y    1    5    2    3
z  NaN  NaN  NaN  NaN

NoGit extension simply hides the problem, by turning off the Git source control provider each time the solution is loaded. It does this job for every solution that is loaded in Visual Studio.

I solved by opening another project and removing the Git repository from the Local Git Repositories, as Chris C. suggested (View > Team Explorer > Local Git Repositories, select the repository that has to be removed and click Remove). Then I removed .git folder from the project path, as suggested by helix. Reopened the project and finally Git integration was gone!

If you want for some reason to convert your file to base-64 string. Like if you want to pass it via internet, etc... you can do this

Byte[] bytes = File.ReadAllBytes("path");
String file = Convert.ToBase64String(bytes);

And correspondingly, read back to file:

Byte[] bytes = Convert.FromBase64String(b64Str);
File.WriteAllBytes(path, bytes);

I am using:

    ExeConfigurationFileMap configMap = new ExeConfigurationFileMap();
    //configMap.ExeConfigFilename = @"d:\test\justAConfigFile.config.whateverYouLikeExtension";
    configMap.ExeConfigFilename = AppDomain.CurrentDomain.BaseDirectory + ServiceConstants.FILE_SETTING;
    Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configMap, ConfigurationUserLevel.None);
    value1 = System.Configuration.ConfigurationManager.AppSettings["NewKey0"];
    value2 = config.AppSettings.Settings["NewKey0"].Value;
    value3 = ConfigurationManager.AppSettings["NewKey0"];

Where value1 = ... and value3 = ... gives null and value2 = ... works

Then I decided to replace the internal app.config with:

// Note works in service but not in wpf
AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", @"d:\test\justAConfigFile.config.whateverYouLikeExtension");
ConfigurationManager.RefreshSection("appSettings");

string value = ConfigurationManager.AppSettings["NewKey0"];

Why it does not work

There is no datetime dtype to be set for read_csv as csv files can only contain strings, integers and floats.

Setting a dtype to datetime will make pandas interpret the datetime as an object, meaning you will end up with a string.

Pandas way of solving this

The pandas.read_csv() function has a keyword argument called parse_dates

Using this you can on the fly convert strings, floats or integers into datetimes using the default date_parser (dateutil.parser.parser)

headers = ['col1', 'col2', 'col3', 'col4']
dtypes = {'col1': 'str', 'col2': 'str', 'col3': 'str', 'col4': 'float'}
parse_dates = ['col1', 'col2']
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes, parse_dates=parse_dates)

This will cause pandas to read col1 and col2 as strings, which they most likely are ("2016-05-05" etc.) and after having read the string, the date_parser for each column will act upon that string and give back whatever that function returns.

Defining your own date parsing function:

The pandas.read_csv() function also has a keyword argument called date_parser

Setting this to a lambda function will make that particular function be used for the parsing of the dates.

GOTCHA WARNING

You have to give it the function, not the execution of the function, thus this is Correct

date_parser = pd.datetools.to_datetime

This is incorrect:

date_parser = pd.datetools.to_datetime()

Pandas 0.22 Update

pd.datetools.to_datetime has been relocated to date_parser = pd.to_datetime

If you only want to animate the height of a view (from say 0 to a certain number) you could implement your own animation:

final View v = getTheViewToAnimateHere();
Animation anim=new Animation(){
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        super.applyTransformation(interpolatedTime, t);
        // Do relevant calculations here using the interpolatedTime that runs from 0 to 1
        v.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, (int)(30*interpolatedTime)));
    }};
anim.setDuration(500);
v.startAnimation(anim);

Mine was more of a mistake, what happened was loop click(i guess) basically by clicking on the login the parent was also clicked which ended up causing Maximum call stack size exceeded.

$('.clickhere').click(function(){
   $('.login').click();
});

<li class="clickhere">
  <a href="#" class="login">login</a>
</li>

Based on the C99 Specification: a == (a / b) * b + a % b

We can write a function to calculate (a % b) == a - (a / b) * b!

int remainder(int a, int b)
{
    return a - (a / b) * b;
}

For modulo operation, we can have the following function (assuming b > 0)

int mod(int a, int b)
{
    int r = a % b;
    return r < 0 ? r + b : r;
}

My conclusion is that a % b in C is a remainder operation and NOT a modulo operation.

.yaml is apparently the official extension, because some applications fail when using .yml. On the other hand I am not familiar with any applications which use YAML code, but fail with a .yaml extension.

I just stumbled across this, as I was used to writing .yml in Ansible and Docker Compose. Out of habit I used .yml when writing Netplan files which failed silently. I finally figured out my mistake. The author of a popular Ansible Galaxy role for Netplan makes the same assumption in his code:

- name: Capturing Existing Configurations
  find:
    paths: /etc/netplan
    patterns: "*.yml,*.yaml"
  register: _netplan_configs

Yet any files with a .yml extension get ignored by Netplan in the same way as files with a .bak extension. As Netplan is very quiet, and gives no feedback whatsoever on success, even with netplan apply --debug, a config such as 01-netcfg.yml will fail silently without any meaningful feedback.

You need to set ulimit -c. If you have 0 for this parameter a coredump file is not created. So do this: ulimit -c unlimited and check if everything is correct ulimit -a. The coredump file is created when an application has done for example something inappropriate. The name of the file on my system is core.<process-pid-here>.

Just in case someone still needs it. The successful, not official, way to rename indexes are:

1. Close indexes that need to be renamed
2. Rename indexes' folders in all data directories of master and data nodes.
3. Reopen old closed indexes (I use kofp plugin). Old indexes will be reopened but stay unassigned. New indexes will appear in closed state
4. Reopen new indexes
5. Delete old indexes

If you happen to get this error "dangled index directory name is", remove index folder in all master nodes (not data nodes), and restart one of the data nodes.

Use brackets. So to look for 75%

WHERE MyCol LIKE '%75[%]%'

This is simpler than ESCAPE and common to most RDBMSes.

This creates a DataFrame because you passed a list of columns (single, but still a list). When you later do this:

gene_name[x]

you now have a Series object with a single value. You can't hash the Series.

The solution is to create Series from the start.

gene_type = no_headers.iloc[1:,0]
gene_name = no_headers.iloc[1:,1]
disease_name = no_headers.iloc[1:,2]

Also, where you have orph_dict[gene_name[x]] =+ 1, I'm guessing that's a typo and you really mean orph_dict[gene_name[x]] += 1 to increment the counter.

The currently accepted answer doesn't always work.

(To read about the problem and circumstances, read this: Defined function is "Not defined".)

So, you have 3 options:

1 (it has above-mentioned drawback)

<input type="checkbox" onchange="doAlert(this)">

<script>
function doAlert(checkboxElem) {
    if (checkboxElem.checked) {
        alert ('hi');
    } else {
        alert ('bye');
    }
}
</script>

2 and 3

<input type="checkbox" id="foo">

<script>
function doAlert() {
    var input = document.querySelector('#foo');

    // input.addEventListener('change', function() { ... });
    // or
    // input.onchange = function() { ... };
    input.addEventListener('change', function() {
        if (input.checked) {
            alert ('hi');
        } else {
            alert ('bye');
        }
    });
}

doAlert();
</script>

On Mac Intellij 12.1.2 there is no File-Settings:

There is an application-name menu item to the left of "File" with a "preferences" menu item:

and within that is the "Settings" dialog shown by the Windows Intellij.

its working with this code

text-align: justify; text-align-last: center;

break breaks out of a loop, not an if statement, as others have pointed out. The motivation for this isn't too hard to see; think about code like

for item in some_iterable:
    ...
    if break_condition():
        break 

The break would be pretty useless if it terminated the if block rather than terminated the loop -- terminating a loop conditionally is the exact thing break is used for.

If you can use some dynamic query, you can use LEN . It will give false on both empty and null string. By this way you can implement the option parameter.

ALTER PROCEDURE [dbo].[psProducts] 
(@SearchType varchar(50))
AS
BEGIN
    SET NOCOUNT ON;

DECLARE @Query nvarchar(max) = N'
    SELECT 
        P.[ProductId],
        P.[ProductName],
        P.[ProductPrice],
        P.[Type]
    FROM [Product] P'
    -- if @Searchtype is not null then use the where clause
    SET @Query = CASE WHEN LEN(@SearchType) > 0 THEN @Query + ' WHERE p.[Type] = ' + ''''+ @SearchType + '''' ELSE @Query END   

    EXECUTE sp_executesql @Query
    PRINT @Query
END

I don't know of any built-in way to do this. However, it would seem easy enough to do, since the only delimiters you have to worry about are the newline character and the equals sign.

It would be very easy to write a routine that will return a NameValueCollection, or an IDictionary given the contents of the file.

The difference is in which lock is being acquired:

• synchronized method acquires a lock on the whole object. This means no other thread can use any synchronized method in the whole object while the method is being run by one thread.

• synchronized blocks acquires a lock in the object between parentheses after the synchronized keyword. Meaning no other thread can acquire a lock on the locked object until the synchronized block exits.

So if you want to lock the whole object, use a synchronized method. If you want to keep other parts of the object accessible to other threads, use synchronized block.

If you choose the locked object carefully, synchronized blocks will lead to less contention, because the whole object/class is not blocked.

This applies similarly to static methods: a synchronized static method will acquire a lock in the whole class object, while a synchronized block inside a static method will acquire a lock in the object between parentheses.

The package it-self is located under /data/app/com.company.appname-xxx.apk.

/data/app/com.company.appname is only a directory created to store files like native libs, cache, ecc...

You can retrieve the package installation path with the Context.getPackageCodePath() function call.

As you stated in the comments, some of the values appeared to be floats, not strings. You will need to change it to strings before passing it to re.sub. The simplest way is to change location to str(location) when using re.sub. It wouldn't hurt to do it anyways even if it's already a str.

letters_only = re.sub("[^a-zA-Z]",  # Search for all non-letters
                          " ",          # Replace all non-letters with spaces
                          str(location))

The following will round positive or negative numbers to a given decimal position:

sub round ()
{
    my ($x, $pow10) = @_;
    my $a = 10 ** $pow10;

    return (int($x / $a + (($x < 0) ? -0.5 : 0.5)) * $a);
}

So I started writing my own, just bare bones functionality for now, will be working on it next week... http://jsfiddle.net/ydTCZ/

Considering that you are using OpenCV, the best way to convert between data types is to use normalize function.

img_n = cv2.normalize(src=img, dst=None, alpha=0, beta=255, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_8U)

However, if you don't want to use OpenCV, you can do this in numpy

def convert(img, target_type_min, target_type_max, target_type):
    imin = img.min()
    imax = img.max()

    a = (target_type_max - target_type_min) / (imax - imin)
    b = target_type_max - a * imax
    new_img = (a * img + b).astype(target_type)
    return new_img

And then use it like this

imgu8 = convert(img16u, 0, 255, np.uint8)

This is based on the answer that I found on crossvalidated board in comments under this solution https://stats.stackexchange.com/a/70808/277040

If your web server is IIS, you need to make sure that the new Office 2007 (I see the xlsx suffix) mime types are added to the list of mime types in IIS, otherwise it will refuse to serve the unknown file type.

Here's one link to tell you how:

Configuring IIS 6 for Office 2007

A URL must not contain a literal space. It must either be encoded using the percent-encoding or a different encoding that uses URL-safe characters (like application/x-www-form-urlencoded that uses + instead of %20 for spaces).

But whether the statement is right or wrong depends on the interpretation: Syntactically, a URI must not contain a literal space and it must be encoded; semantically, a %20 is not a space (obviously) but it represents a space.

For v5 please use initialDate instead of defaultDate. Simply renamed option

eg

var calendarEl = document.getElementById('calendar');
var calendar = new FullCalendar.Calendar(calendarEl, {
     ...
     initialDate: '2020-09-02',
     ...
});

For me, the issue was I had git and my macOS filesystem set to two different case sensitivities. My Mac was formatted APFS/Is Case-Sensitive: NO but I had flipped my git settings at some point trying to get over a weird issue with Xcode image asset naming so git config --global core.ignorecase false. By flipping it back aligned the settings and recreating the branch and pushing got me back on track.

git config --global core.ignorecase true

I suggest going straight for the model approach in Swing. After you've put the component in the panel and layout manager, don't even bother keeping a specific reference to it.

If you really want the widget, then you can test each with isSelected, or maintain a Map<ButtonModel,JRadioButton>.

I've used this in the past, and it does a good job. It's not free, but you should definitely take a look.
JavaScript Obfuscator & Encoder

Apply this code in your css

::-webkit-scrollbar{

    -webkit-appearance: none;
    width: 7px;

}

::-webkit-scrollbar-thumb {

    border-radius: 4px;
    background-color: rgba(0,0,0,.5); 
    -webkit-box-shadow: 0 0 1px rgba(255,255,255,.5);
}

In case it helps someone else, I was able to convert to an array by doing something like this,

JSONObject jsonObject = (JSONObject)new JSONParser().parse(jsonString);
((JSONArray) jsonObject).toArray()

...or you should be able to get the length

((JSONArray) myJsonArray).toArray().length

First of all, a modified version of your service.

a )

var app = angular.module('app',[]);

app.factory('ExampleService',function(){
    return {
        f1 : function(world){
            return 'Hello' + world;
        }
    };
});

This returns an object, nothing to new here.

Now the way to get this from the console is

b )

var $inj = angular.injector(['app']);
var serv = $inj.get('ExampleService');
serv.f1("World");

c )

One of the things you were doing there earlier was to assume that the app.factory returns you the function itself or a new'ed version of it. Which is not the case. In order to get a constructor you would either have to do

app.factory('ExampleService',function(){
        return function(){
            this.f1 = function(world){
                return 'Hello' + world;
            }
        };
    });

This returns an ExampleService constructor which you will next have to do a 'new' on.

Or alternatively,

app.service('ExampleService',function(){
            this.f1 = function(world){
                return 'Hello' + world;
            };
    });

This returns new ExampleService() on injection.

NSData *data = [strChangetoJSON dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data
                                                             options:kNilOptions
                                                               error:&error];

For example you have a NSString with special characters in NSString strChangetoJSON. Then you can convert that string to JSON response using above code.

That's basically a set of 2 simultaneous equations:

x*y = a
X+y = b

(using the mathematical convention of x and y for the variables to solve and a and b for arbitrary constants).

But the solution involves a quadratic equation (because of the x*y), so depending on the actual values of a and b, there may not be a solution, or there may be multiple solutions.

I don't believe there will be a collision. Using static at the file level (outside functions) marks the variable as local to the current compilation unit (file). It's never visible outside the current file so never has to have a name that can be used externally.

Using static inside a function is different - the variable is only visible to the function (whether static or not), it's just its value is preserved across calls to that function.

In effect, static does two different things depending on where it is. In both cases however, the variable visibility is limited in such a way that you can easily prevent namespace clashes when linking.

Having said that, I believe it would be stored in the DATA section, which tends to have variables that are initialized to values other than zero. This is, of course, an implementation detail, not something mandated by the standard - it only cares about behaviour, not how things are done under the covers.

For reference, be aware that you might be dismissing the wrong view controller. For example, if you have an alert box or modal showing on top of another modal. (You could have a Twitter post alert showing on top of your current modal alert, for example). In this case, you need to call dismiss twice, or use an unwind segue.

also works if you do a "display: block;" on the td, destroying the td identity, but works!

Simply add these two functions in your viewcontroller it will solve your problem. Here, list is a string array which contain your string of every row.

 func tableView(_ tableView: UITableView, 
   estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
        tableView.rowHeight = self.calculateHeight(inString: list[indexPath.row])

    return (tableView.rowHeight) 
}

func calculateHeight(inString:String) -> CGFloat
{
    let messageString = input.text
    let attributes : [NSAttributedStringKey : Any] = [NSAttributedStringKey(rawValue: NSAttributedStringKey.font.rawValue) : UIFont.systemFont(ofSize: 15.0)]

    let attributedString : NSAttributedString = NSAttributedString(string: messageString!, attributes: attributes)

    let rect : CGRect = attributedString.boundingRect(with: CGSize(width: 222.0, height: CGFloat.greatestFiniteMagnitude), options: .usesLineFragmentOrigin, context: nil)

    let requredSize:CGRect = rect
    return requredSize.height
}

If you have a string that only contains ASCII characters, you can use this method.

    public static string ASCIIReverse(string s)
    {
        byte[] reversed = new byte[s.Length];

        int k = 0;
        for (int i = s.Length - 1; i >= 0; i--)
        {
            reversed[k++] = (byte)s[i];
        }

        return Encoding.ASCII.GetString(reversed);
    }
