To add to all the wonderful answers here

First of all float and double are both used for representation of numbers fractional numbers. So, the difference between the two stems from the fact with how much precision they can store the numbers.

For example: I have to store 123.456789 One may be able to store only 123.4567 while other may be able to store the exact 123.456789.

So, basically we want to know how much accurately can the number be stored and is what we call precision.

Quoting @Alessandro here

The precision indicates the number of decimal digits that are correct, i.e. without any kind of representation error or approximation. In other words, it indicates how many decimal digits one can safely use.

Float can accurately store about 7-8 digits in the fractional part while Double can accurately store about 15-16 digits in the fractional part

So, float can store double the amount of fractional part. That is why Double is called double the float

I tested the performance of FileInputStream vs. FileChannel for decoding base64 encoded files. In my experients I tested rather large file and traditional io was alway a bit faster than nio.

FileChannel might have had an advantage in prior versions of the jvm because of synchonization overhead in several io related classes, but modern jvm are pretty good at removing unneeded locks.

SELECT * FROM testcases1 t WHERE NOT EXISTS ( SELECT 1
FROM executions1 i WHERE t.tc_id = i.tc_id and t.pro_id=i.pro_id and pro_id=7 and version_id=5 ) and pro_id=7 ;

Here testcases1 table contains all datas and executions1 table contains some data among testcases1 table. I am retrieving only the datas which are not present in exections1 table. ( and even I am giving some conditions inside that you can also give.) specify condition which should not be there in retrieving data should be inside brackets.

People seem to be over complicating this.. Just combine the two lists, then sort them:

>>> l1 = [1, 3, 4, 7]
>>> l2 = [0, 2, 5, 6, 8, 9]
>>> l1.extend(l2)
>>> sorted(l1)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

..or shorter (and without modifying l1):

>>> sorted(l1 + l2)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

..easy! Plus, it's using only two built-in functions, so assuming the lists are of a reasonable size, it should be quicker than implementing the sorting/merging in a loop. More importantly, the above is much less code, and very readable.

If your lists are large (over a few hundred thousand, I would guess), it may be quicker to use an alternative/custom sorting method, but there are likely other optimisations to be made first (e.g not storing millions of datetime objects)

Using the timeit.Timer().repeat() (which repeats the functions 1000000 times), I loosely benchmarked it against ghoseb's solution, and sorted(l1+l2) is substantially quicker:

merge_sorted_lists took..

[9.7439379692077637, 9.8844599723815918, 9.552299976348877]

sorted(l1+l2) took..

[2.860386848449707, 2.7589840888977051, 2.7682540416717529]

Use the following sudo command:

sudo yum install java-1.6.0-openjdk-devel

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

   bottomNavigationView.setOnNavigationItemSelectedListener(this);
   Menu menu = bottomNavigationView.getMenu();
   this.onNavigationItemSelected(menu.findItem(R.id.action_favorites));
}

I think you are right by saying that people cannot click half pixels, so personally, I would use rounded jQuery offset...

The proper way to do it is by using tput or terminfo functions to obtain terminal properties and then insert newlines according to the dimensions..

The height of a block element defaults to the height of the block's content. So, given something like this:

<div id="outer">
    <div id="inner">
        <p>Where is pancakes house?</p>
    </div>
</div>

#inner will grow to be tall enough to contain the paragraph and #outer will grow to be tall enough to contain #inner.

When you specify the height or width as a percentage, that's a percentage with respect to the element's parent. In the case of width, all block elements are, unless specified otherwise, as wide as their parent all the way back up to <html>; so, the width of a block element is independent of its content and saying width: 50% yields a well defined number of pixels.

However, the height of a block element depends on its content unless you specify a specific height. So there is feedback between the parent and child where height is concerned and saying height: 50% doesn't yield a well defined value unless you break the feedback loop by giving the parent element a specific height.

The size of a structure is greater than the sum of its parts because of what is called packing. A particular processor has a preferred data size that it works with. Most modern processors' preferred size if 32-bits (4 bytes). Accessing the memory when data is on this kind of boundary is more efficient than things that straddle that size boundary.

For example. Consider the simple structure:

struct myStruct
{
   int a;
   char b;
   int c;
} data;

If the machine is a 32-bit machine and data is aligned on a 32-bit boundary, we see an immediate problem (assuming no structure alignment). In this example, let us assume that the structure data starts at address 1024 (0x400 - note that the lowest 2 bits are zero, so the data is aligned to a 32-bit boundary). The access to data.a will work fine because it starts on a boundary - 0x400. The access to data.b will also work fine, because it is at address 0x404 - another 32-bit boundary. But an unaligned structure would put data.c at address 0x405. The 4 bytes of data.c are at 0x405, 0x406, 0x407, 0x408. On a 32-bit machine, the system would read data.c during one memory cycle, but would only get 3 of the 4 bytes (the 4th byte is on the next boundary). So, the system would have to do a second memory access to get the 4th byte,

Now, if instead of putting data.c at address 0x405, the compiler padded the structure by 3 bytes and put data.c at address 0x408, then the system would only need 1 cycle to read the data, cutting access time to that data element by 50%. Padding swaps memory efficiency for processing efficiency. Given that computers can have huge amounts of memory (many gigabytes), the compilers feel that the swap (speed over size) is a reasonable one.

Unfortunately, this problem becomes a killer when you attempt to send structures over a network or even write the binary data to a binary file. The padding inserted between elements of a structure or class can disrupt the data sent to the file or network. In order to write portable code (one that will go to several different compilers), you will probably have to access each element of the structure separately to ensure the proper "packing".

On the other hand, different compilers have different abilities to manage data structure packing. For example, in Visual C/C++ the compiler supports the #pragma pack command. This will allow you to adjust data packing and alignment.

For example:

#pragma pack 1
struct MyStruct
{
    int a;
    char b;
    int c;
    short d;
} myData;

I = sizeof(myData);

I should now have the length of 11. Without the pragma, I could be anything from 11 to 14 (and for some systems, as much as 32), depending on the default packing of the compiler.

Here upload and preview part done.Now if you want to delete and remove image from page and folder both then code is here for deletion. Ajax Part:

function removeit (arg) {
       var id  = arg;
       // GET FILE VALUE
       var fname = $('#filename').val();
       var fcnt = $('#filecount').val();
        // GET FILE VALUE

       $('#img_'+id).remove();
       $('#rmv_'+id).remove();
       $('#img_'+id).css('display','none');

        var dname  =  $('#name_'+id).val();
        fcnt = parseInt(fcnt)-1;
        $('#filecount').val(fcnt);
        var fname = fname.replace(dname, "");

            console.log(a);
            }

The answer that works on Ubuntu18, python3, opencv 3.2.0 is similar to the one above. But with the change in line cv2.waitKey(0). that means the program waits until a button is pressed.

With this code I found the key value for the arrow buttons: arrow up (82), down (84), arrow left(81) and Enter(10) and etc..

import cv2
img = cv2.imread('sof.jpg') # load a dummy image
while(1):
    cv2.imshow('img',img)
    k = cv2.waitKey(0)
    if k==27:    # Esc key to stop
        break
    elif k==-1:  # normally -1 returned,so don't print it
        continue
    else:
        print k # else print its value

Since Support for the ADT in Eclipse has ended, we have to use Android Studio.

There is a way to skip the errors inside the code and go on with the loop anyway, hope it helps:

Sub new1()

Dim wsFunc As WorksheetFunction: Set wsFunc = Application.WorksheetFunction
Dim ws As Worksheet: Set ws = Sheets(1)
Dim rngLook As Range: Set rngLook = ws.Range("A:M")

currName = "Example"
On Error Resume Next ''if error, the code will go on anyway
cellNum = wsFunc.VLookup(currName, rngLook, 13, 0)

If Err.Number <> 0 Then
''error appeared
    MsgBox "currName not found" ''optional, no need to do anything
End If

On Error GoTo 0 ''no error, coming back to default conditions

End Sub

You'll definitely want to check out this positioning article from 'A List Apart'. Helped demystify CSS positioning (which seemed insane to me, prior to this article).

I do that as

    $slightly_damaged = array_merge(
        array_slice($slightly_damaged, 0, 4, true) + ["4" => "0.0"], 
        array_slice($slightly_damaged, 4, count($slightly_damaged) - 4, true)
    );

From the OP:

I finally reinstalled it from Java for OS X 2013-005. It solved this issue.

Another case is with Webpack which concating angular into the bundle.js, beside the angular that is loaded from index.html <script> tag.

this was because we used explicit importing of angular in many files:

define(['angular', ...], function(angular, ...){

so, webpack decided to bundle it too. cleaning all of those into:

define([...], function(...){

was fixing Tried to Load Angular More Than Once for once and all.

In your Case you can write the following jquery code:

$(document).ready(function(){

   $('.staff_on_site').click(function(){

     var rBtnVal = $(this).val();

     if(rBtnVal == "yes"){
         $("#no_of_staff").attr("readonly", false); 
     }
     else{ 
         $("#no_of_staff").attr("readonly", true); 
     }
   });
});

This version works fairly well. It simply checks whether vim71 is in the path, and prepends it if not.

@echo off
echo %PATH% | find /c /i "vim71" > nul
if not errorlevel 1 goto jump
PATH = C:\Program Files\Vim\vim71\;%PATH%
:jump

This demo is to illustrate the errorlevel logic:

@echo on
echo %PATH% | find /c /i "Windows"
if "%errorlevel%"=="0" echo Found Windows
echo %PATH% | find /c /i "Nonesuch"
if "%errorlevel%"=="0" echo Found Nonesuch

The logic is reversed in the vim71 code since errorlevel 1 is equivalent to errorlevel >= 1. It follows that errorlevel 0 would always evaluate true, so "not errorlevel 1" is used.

Postscript Checking may not be necessary if you use setlocal and endlocal to localise your environment settings, e.g.

@echo off
setlocal
PATH = C:\Program Files\Vim\vim71\;%PATH%
rem your code here
endlocal

After endlocal you are back with your original path.

A lambda can only be converted to a function pointer if it does not capture, from the draft C++11 standard section 5.1.2 [expr.prim.lambda] says (emphasis mine):

The closure type for a lambda-expression with no lambda-capture has a public non-virtual non-explicit const conversion function to pointer to function having the same parameter and return types as the closure type’s function call operator. The value returned by this conversion function shall be the address of a function that, when invoked, has the same effect as invoking the closure type’s function call operator.

Note, cppreference also covers this in their section on Lambda functions.

So the following alternatives would work:

typedef bool(*DecisionFn)(int);

Decide greaterThanThree{ []( int x ){ return x > 3; } };

and so would this:

typedef bool(*DecisionFn)();

Decide greaterThanThree{ [](){ return true ; } };

and as 5gon12eder points out, you can also use std::function, but note that std::function is heavy weight, so it is not a cost-less trade-off.

I'd like to share my experience of using Ant in building projects, *.properties files should be copied explicitly. This is because Ant will not compile *.properties files into the build working directory by default (javac just ignore *.properties). For example:

<target name="compile" depends="init">
    <javac destdir="${dst}" srcdir="${src}" debug="on" encoding="utf-8" includeantruntime="false">
        <include name="com/example/**" />
        <classpath refid="libs" />
    </javac>
    <copy todir="${dst}">
        <fileset dir="${src}" includes="**/*.properties" />
    </copy>
</target>

<target name="jars" depends="compile">
    <jar jarfile="${app_jar}" basedir="${dst}" includes="com/example/**/*.*" />
</target>

Please notice that 'copy' section under the 'compile' target, it will replicate *.properties files into the build working directory. Without the 'copy' section the jar file will not contain the properties files, then you may encounter the java.util.MissingResourceException.

A collection of the four seemingly most compatible methods from this page. The first one's really quite genius. Tested from XP up. Confusing though that there is no standard command available to check for admin rights. I guess they're simply focusing on PowerShell now, which is really useless for most of my own work.

Run away from store procedures as much as possible. They are pretty hard to maintain and are VERY OLD STUFF ;)

If you are using the script approach and have an error concerning the LDF and MDF files, you can first query the the backup file for the logical names (and other details) of files in the backup set, using the following:

-- Queries the backup file for the file list in backup set, where Type denotes 
-- type of file. Can be L,D,F or S
-- info: https://docs.microsoft.com/en-us/sql/t-sql/statements/restore-statements-filelistonly-transact-sql
RESTORE FILELISTONLY FROM DISK = 'C:\Temp\DB_backup.bak'
GO

You will get results similar to the following:

And then you can use those logical names in the queries:

    -- Script assumes you want MDF and LDF files restored on separate drives. Modify for your scenario
    RESTORE DATABASE DB 
    FROM DISK='C:\Temp\DB_backup.bak'
    WITH REPLACE,
      MOVE 'DB' TO 'E:\MSSQL\Data\DB.mdf', -- "DB" is the mdf logical name from query above
      MOVE 'DB_log' TO 'F:\MSSQL\Logs\DB.ldf'; -- "DB_log" is LDF logical name from query above

More info on RESTORE FILELISTONLY can be found from the SQL Server docs.

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

gahooa's answer is correct for the question as phrased in the heading, but if the lists are already numpy format or larger than ten it will be MUCH faster (3 orders of magnitude) as well as more readable, to do simple numpy multiplication as suggested by NPE. I get these timings:

0.0049ms -> N = 4, a = [i for i in range(N)], c = [a*b for a,b in zip(a, b)]
0.0075ms -> N = 4, a = [i for i in range(N)], c = a * b
0.0167ms -> N = 4, a = np.arange(N), c = [a*b for a,b in zip(a, b)]
0.0013ms -> N = 4, a = np.arange(N), c = a * b
0.0171ms -> N = 40, a = [i for i in range(N)], c = [a*b for a,b in zip(a, b)]
0.0095ms -> N = 40, a = [i for i in range(N)], c = a * b
0.1077ms -> N = 40, a = np.arange(N), c = [a*b for a,b in zip(a, b)]
0.0013ms -> N = 40, a = np.arange(N), c = a * b
0.1485ms -> N = 400, a = [i for i in range(N)], c = [a*b for a,b in zip(a, b)]
0.0397ms -> N = 400, a = [i for i in range(N)], c = a * b
1.0348ms -> N = 400, a = np.arange(N), c = [a*b for a,b in zip(a, b)]
0.0020ms -> N = 400, a = np.arange(N), c = a * b

i.e. from the following test program.

import timeit

init = ['''
import numpy as np
N = {}
a = {}
b = np.linspace(0.0, 0.5, len(a))
'''.format(i, j) for i in [4, 40, 400] 
                  for j in ['[i for i in range(N)]', 'np.arange(N)']]

func = ['''c = [a*b for a,b in zip(a, b)]''',
'''c = a * b''']

for i in init:
  for f in func:
    lines = i.split('\n')
    print('{:6.4f}ms -> {}, {}, {}'.format(
           timeit.timeit(f, setup=i, number=1000), lines[2], lines[3], f))

Installing .NET 4.7 worked for me. I only had 3.5 installed prior.

First time I have added a video link for solving your problem but I learned it was a bad idea. This time I'll explain it briefly.

Android studio is compatible with github but you need adjust something:

1. Setup Android Studio

2. Setup the Github plugins in the Android Studio settings

   • Android Studio settings >> Plugins page

3. Download the git version control system from this link and setup https://git-scm.com/

4. After the installation, open Android Studio settings page and select the git.exe
   • settings >> version control >> git
   • Usually the path to git.exe is program files >> git >> bin >> git.exe
5. Go to Settings >> Version control >> Github you will see login and password for your Github account. Apply the settings.
6. For updating the project, go in Android Studio top line click VCS >> enable version control integration >> git
7. One more time VCS >> import into version control >> share project on Github and enter your master password.

Now you can use VCS update buttons for updating your project to Github

Just type import pdb in jupyter notebook, and then use this cheatsheet to debug. It's very convenient.

c --> continue, s --> step, b 12 --> set break point at line 12 and so on.

    mBuilder.setSmallIcon(R.drawable.ic_push_notification);
}

you can test if have exactly some values, by example:

for(MyBoolean b : MyBoolean.values()) {
    switch(b) {
    case TRUE:
        break;
    case FALSE:
        break;
    default:
        throw new IllegalArgumentException(b.toString());
}

for(String s : new String[]{"TRUE", "FALSE" }) {
    MyBoolean.valueOf(s);
}

If someone removes or adds a value, some of test fails.

This works well for me:

from matplotlib import pyplot as plt

F = plt.gcf()
Size = F.get_size_inches()
F.set_size_inches(Size[0]*2, Size[1]*2, forward=True) # Set forward to True to resize window along with plot in figure.
plt.show() # or plt.imshow(z_array) if using an animation, where z_array is a matrix or numpy array

Very simple

let file = $("#fileupload")[0].files[0];

An ASP.NET HTTP handler is the process (frequently referred to as the "endpoint") that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler. You can create your own HTTP handlers that render custom output to the browser.

I think that the answer is that it depends on a whole range of factors such as:

• whether the list size can be predicted beforehand (i.e. can you set the capacity accurately),
• whether the list size is variable (i.e. each time it is filled),
• how long the lifetime of the list will be in both versions, and
• your heap / GC parameters and CPU.

These make it hard to predict which will be better. But my intuition is that the difference will not be that great.

Two bits of advice on optimization:

• Don't waste time trying to optimize this ... unless the application is objectively too slow AND measurement using a profiler tells you that this is a performance hotspot. (The chances are that one of those preconditions won't be true.)

• If you do decide to optimize this, do it scientifically. Try both (all) of the alternatives and decide which is best by measuring the performance in your actual application on a realistic problem / workload / input set. (An artificial benchmark is liable to give you answers that do not predict real-world behavior, because of factors like those I listed previously.)

Further to the answer from ktbos:

I modified the mysqld.cnf file and mysql failed to start. It turned out that I was modifying the wrong file!

So be sure the file you modify contains segment tags like [mysqld_safe] and [mysqld]. Under the latter I did as suggested and added the line:

validate_password_policy=LOW

This worked perfectly to resolve my issue of not requiring special characters within the password.

You cannot (except the type of a particular iterator implements some specific methods that make it possible).

Generally, you may count iterator items only by consuming the iterator. One of probably the most efficient ways:

import itertools
from collections import deque

def count_iter_items(iterable):
    """
    Consume an iterable not reading it into memory; return the number of items.
    """
    counter = itertools.count()
    deque(itertools.izip(iterable, counter), maxlen=0)  # (consume at C speed)
    return next(counter)

(For Python 3.x replace itertools.izip with zip).

If your delimiter is only characters, you can use strtok, which seems to be more fit here. Note that you must use it with a while loop to achieve the effects.

Here's a quick jQuery example that adds a click event to each "li" tag, and then retrieves the class attribute for the clicked element. Hope it helps.

$("li").click(function() {
   var myClass = $(this).attr("class");
   alert(myClass);
});

Equally, you don't have to wrap the object in jQuery:

$("li").click(function() {
   var myClass = this.className;
   alert(myClass);
});

And in newer browsers you can get the full list of class names:

$("li").click(function() {
   var myClasses = this.classList;
   alert(myClasses.length + " " + myClasses[0]);
});

You can emulate classList in older browsers using myClass.split(/\s+/);

To check your MySQL version on your mac, navigate to the directory where you installed it (default is usr/local/mysql/bin) and issue this command:

./mysql --version

Alternatively, to avoid needing to navigate to that specific dir to run the command, add its location to your path ($PATH). There's more than one way to add a dir to your $PATH (with explanations on stackoverflow and other places on how to do so), such as adding it to your ./bash_profile.

After adding the mysql bin dir to your $PATH, verify it's there by executing:

echo $PATH

Thereafter you can check your mysql version from anywhere by running (note no "./"):

mysql --version

First create this UDF

CREATE FUNCTION dbo.udf_GetNumeric
(
  @strAlphaNumeric VARCHAR(256)
)
RETURNS VARCHAR(256)
AS
BEGIN
  DECLARE @intAlpha INT
  SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric)
  BEGIN
    WHILE @intAlpha > 0
    BEGIN
      SET @strAlphaNumeric = STUFF(@strAlphaNumeric, @intAlpha, 1, '' )
      SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric )
    END
  END
  RETURN ISNULL(@strAlphaNumeric,0)
END
GO

Now use the function as

SELECT dbo.udf_GetNumeric(column_name) 
from table_name

SQL FIDDLE

I hope this solved your problem.

In C++ the std::string class implements the comparison operators, so you can perform the comparison using == just as you would expect:

if (string == "add") { ... }

When used properly, operator overloading is an excellent C++ feature.

Since you're transferring data in xml, you could also (un)marshal directly from/to pojos.

There's an example (and more info) in the jersey user guide, which I copy here:

POJO with JAXB annotations:

@XmlRootElement
public class Planet {
    public int id;
    public String name;
    public double radius;
}

Resource:

@Path("planet")
public class Resource {

    @GET
    @Produces(MediaType.APPLICATION_XML)
    public Planet getPlanet() {
        Planet p = new Planet();
        p.id = 1;
        p.name = "Earth";
        p.radius = 1.0;

        return p;
    }

    @POST
    @Consumes(MediaType.APPLICATION_XML)
    public void setPlanet(Planet p) {
        System.out.println("setPlanet " + p.name);
    }

}      

The xml that gets produced/consumed:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<planet>
    <id>1</id>
    <name>Earth</name>
    <radius>1.0</radius>
</planet>

You didn't say what version you were using, but in SQL 2005 and above, you can use a common table expression with the OVER Clause. It goes a little something like this:

WITH cte AS (
  SELECT[foo], [bar], 
     row_number() OVER(PARTITION BY foo, bar ORDER BY baz) AS [rn]
  FROM TABLE
)
DELETE cte WHERE [rn] > 1

Play around with it and see what you get.

(Edit: In an attempt to be helpful, someone edited the ORDER BY clause within the CTE. To be clear, you can order by anything you want here, it needn't be one of the columns returned by the cte. In fact, a common use-case here is that "foo, bar" are the group identifier and "baz" is some sort of time stamp. In order to keep the latest, you'd do ORDER BY baz desc)

Have you looked into rasdial?

Just incase anyone wanted to do this and finds this in the future, you can use rasdial.exe from command prompt to connect to a VPN network

ie rasdial "VPN NETWORK NAME" "Username" *

it will then prompt for a password, else you can use "username" "password", this is however less secure

I just wanted to mention that I got a similar error in SQL Server Management Studio 2016, where I basically ignored it. Later, I launched Visual Studio (2015), and this error occurred there as well.

I searched and found the answer here recommending that files be deleted from the

%localappdata%\Microsoft\VisualStudio\14.0\ComponentModelCache

folder. However, in my case, this folder was empty.

Since I remembered that I saw the error in Management Studio first, I checked, and there was a similar folder at

%localappdata%\Microsoft\SQL Server Management Studio\13.0\ComponentModelCache

This folder was not empty. I closed both Visual Studio and Management Studio, and deleted the files from this folder.

Afterwards, both Management Studio and Visual Studio launched without error.

Just use CSS:

<li style='color:#e0e0e0'>something</li>

This is caused if you use the "Use host GPU" setting of the emulator and it will disappear after you uncheck this option. If you still need "Use host GPU", you can just filter out the errors by customizing the Logcat Filter. Enter ^(?!eglCodecCommon) into the "by Log Tag (regex)" field in order to strip out the unwanted lines from the Logcat output.

I know this is an older post, but I'm leaving this for whomever else comes looking in the future.

You can't format line breaks into an option; however, you can use the title attibute to give a mouse-over tooltip to give the full info. Use a short descriptor in the option text and give the full skinny in the title.

<option value="1" title="This is my lengthy explanation of what this selection really means, so since you only see 1 on the drop down list you really know that you're opting to elect me as King of Willywarts!  Always be sure to read the fine print!">1</option>

Simply just use this.props.history.push('/where/to/go');

Since none of the answers above actually explain what happened, I decided to chime in and bring some more details to this issue.

Yes, the solution is to run the MySQL Upgrade command, as follows: mysql_upgrade -u root -p --force, but what happened?

The root cause for this issue is the corruption of performance_schema, which can be caused by:

• Organic corruption (volumes going kaboom, engine bug, kernel driver issue etc)
• Corruption during mysql Patch (it is not unheard to have this happen during a mysql patch, specially for major version upgrades)
• A simple "drop database performance_schema" will obviously cause this issue, and it will present the same symptoms as if it was corrupted

This issue might have been present on your database even before the patch, but what happened on MySQL 5.7.8 specifically is that the flag show_compatibility_56 changed its default value from being turned ON by default, to OFF. This flag controls how the engine behaves on queries for setting and reading variables (session and global) on various MySQL Versions.

Because MySQL 5.7+ started to read and store these variables on performance_schema instead of on information_schema, this flag was introduced as ON for the first releases to reduce the blast radius of this change and to let users know about the change and get used to it.

OK, but why does the connection fail? Because depending on the driver you are using (and its configuration), it may end up running commands for every new connection initiated to the database (like show variables, for instance). Because one of these commands can try to access a corrupted performance_schema, the whole connection aborts before being fully initiated.

So, in summary, you may (it's impossible to tell now) have had performance_schema either missing or corrupted before patching. The patch to 5.7.8 then forced the engine to read your variables out of performance_schema (instead of information_schema, where it was reading it from because of the flag being turned ON). Since performance_schema was corrupted, the connections are failing.

Running MySQL upgrade is the best approach, despite the downtime. Turning the flag on is one option, but it comes with its own set of implications as it was pointed out on this thread already.

Both should work, but weight the consequences and know your choices :)

For Online Judges problems that does not allow StringBuilder or StringBuffer, you can do it in place using char[] as following:

public static String reverse(String input){
    char[] in = input.toCharArray();
    int begin=0;
    int end=in.length-1;
    char temp;
    while(end>begin){
        temp = in[begin];
        in[begin]=in[end];
        in[end] = temp;
        end--;
        begin++;
    }
    return new String(in);
}

One set of familiar operations that you can do in MapReduce is the set of normal SQL operations: SELECT, SELECT WHERE, GROUP BY, ect.

Another good example is matrix multiply, where you pass one row of M and the entire vector x and compute one element of M * x.

Might as well make this an answer. I had the same issue today and it was more of a non-issue than expected. After adding the CORS functionality, you must restart your Flask server (ctrl + c -> python manage.py runserver, or whichever method you use)) in order for the change to take effect, even if the code is correct. Otherwise the CORS will not work in the active instance.

Here's how it looks like for me and it works (Python 3.6.1, Flask 0.12):

factory.py:

from flask import Flask
from flask_cors import CORS  # This is the magic


def create_app(register_stuffs=True):
    """Configure the app and views"""
    app = Flask(__name__)
    CORS(app)  # This makes the CORS feature cover all routes in the app

    if register_stuffs:
        register_views(app)
    return app


def register_views(app):
    """Setup the base routes for various features."""
    from backend.apps.api.views import ApiView
    ApiView.register(app, route_base="/api/v1.0/")

views.py:

from flask import jsonify
from flask_classy import FlaskView, route


class ApiView(FlaskView):
    @route("/", methods=["GET"])
    def index(self):
        return "API v1.0"

    @route("/stuff", methods=["GET", "POST"])
    def news(self):
        return jsonify({
            "stuff": "Here be stuff"
        })

In my React app console.log:

Sending request:
GET /stuff
With parameters:
null
bundle.js:17316 Received data from Api:
{"stuff": "Here be stuff"}

• process.cwd() returns directory where command has been executed (not directory of the node package) if it's has not been changed by 'process.chdir' inside of application.
• __filename returns absolute path to file where it is placed.
• __dirname returns absolute path to directory of __filename.

If you need to load files from your module directory you need to use relative paths.

require('../lib/test');

instead of

var lib  = path.join(path.dirname(fs.realpathSync(__filename)), '../lib');

require(lib + '/test');

It's always relative to file where it called from and don't depend on current work dir.

You need to break;, throw, goto, or return from each of your case labels. In a loop you may also continue.

        switch (searchType)
        {
            case "SearchBooks":
                Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
                Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
                break;

            case "SearchAuthors":
                Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
                Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
                break;
        }

The only time this isn't true is when the case labels are stacked like this:

 case "SearchBooks": // no code inbetween case labels.
 case "SearchAuthors":
    // handle both of these cases the same way.
    break;

We encountered this error after an upgrade from 2008 to 2014 SQL Server where our some of our previous connection strings for local development had a Data Source=./ like this

        <add name="MyLocalDatabase" connectionString="Data Source=./;Initial Catalog=SomeCatalog;Integrated Security=SSPI;Application Name=MyApplication;"/>

Changing that from ./ to either (local) or localhost fixed the problem.

<add name="MyLocalDatabase" connectionString="Data Source=(local);Initial Catalog=SomeCatalog;Integrated Security=SSPI;Application Name=MyApplication;"/>

All I wanted were 1) English only and 2) just enough to build a legacy desktop project written in C. No Azure, no mobile development, no .NET, and no other components that I don't know what to do with.

[Note: Options are in multiple lines for readability, but they should be in 1 line]
vs_community__xxxxxxxxxx.xxxxxxxxxx.exe
    --lang en-US
    --layout ".\Visual Studio Cummunity 2017"
    --add Microsoft.VisualStudio.Workload.NativeDesktop 
    --includeRecommended

I chose "NativeDesktop" from "workload and component ID" site (https://docs.microsoft.com/en-us/visualstudio/install/workload-component-id-vs-community).

The result was about 1.6GB downloaded files and 5GB when installed. I'm sure I could have removed a few unnecessary components to save space, but the list was rather long, so I stopped there.

"--includeRecommended" was the key ingredient for me, which included Windows SDK along with other essential things for building the legacy project.

As part of htmlAttributes,e.g.

Html.BeginForm(
    action, controller, FormMethod.Post, new { enctype="multipart/form-data"})

Or you can pass null for action and controller to get the same default target as for BeginForm() without any parameters:

Html.BeginForm(
    null, null, FormMethod.Post, new { enctype="multipart/form-data"})

Probably is the use of the "on" event that Bootstrap use a lot and was inserted at jQuery 1.7 http://api.jquery.com/on/

In your button1_click function you are using '==' for button2.Enabled == true;

This should be button2.Enabled = true;

Using bootstrap, if you need to also add some values to the option to use for filters or other stuff you can simply add the class "bs-title-option" to the option that you want as a placeholder:

<select class="form-group">
   <option class="bs-title-option" value="myVal">My PlaceHolder</option>
   <option>A</option>
   <option>B</option>
   <option>c</option>
</select>

Bootstrap adds this class to the title attribute.

Starting from iOS 7, the system always returns the value 02:00:00:00:00:00 when you ask for the MAC address on any device.

In iOS 7 and later, if you ask for the MAC address of an iOS device, the system returns the value 02:00:00:00:00:00. If you need to identify the device, use the identifierForVendor property of UIDevice instead. (Apps that need an identifier for their own advertising purposes should consider using the advertisingIdentifier property of ASIdentifierManager instead.)"

Another way would be adding __getitem__, __setitem__ function

def __getitem__(self, key):
    return getattr(self, key)

You can use self[key] to access now.

I ended up using this handy macro:

#define STRING(value)               [@(value) stringValue]

OIDs being phased out

The core team responsible for Postgres is gradually phasing out OIDs.

Postgres 12 removes special behavior of OID columns

The use of OID as an optional system column on your tables is now removed from Postgres 12. You can no longer use:

• CREATE TABLE … WITH OIDS command
• default_with_oids (boolean) compatibility setting

The data type OID remains in Postgres 12. You can explicitly create a column of the type OID.

After migrating to Postgres 12, any optionally-defined system column oid will no longer be invisible by default. Performing a SELECT * will now include this column. Note that this extra “surprise” column may break naïvely written SQL code.

You can use this method also it will act like that

thadari=[1,2,3,4,5,6]

#Front Two(Left)
print(thadari[:2])
[1,2]

#Last Two(Right)# edited
print(thadari[-2:])
[5,6]

#mid
mid = len(thadari) //2

lefthalf = thadari[:mid]
[1,2,3]
righthalf = thadari[mid:]
[4,5,6]

Hope it will help

Currently it only works for the .dropdown-menu:

.dropdown-menu .divider {
  height: 1px;
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

If you want it for other use, in your own css, following the bootstrap.css create another one:

.divider {
  height: 1px;
  width:100%;
  display:block; /* for use on default inline elements like span */
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

I see three solutions to this:

1. Change the output encoding, so it will always output UTF-8. See e.g. Setting the correct encoding when piping stdout in Python, but I could not get these example to work.

2. Following example code makes the output aware of your target charset.

   # -*- coding: utf-8 -*-
   import sys
   
   print sys.stdout.encoding
   print u"Stöcker".encode(sys.stdout.encoding, errors='replace')
   print u"????????".encode(sys.stdout.encoding, errors='replace')
   

   This example properly replaces any non-printable character in my name with a question mark.

   If you create a custom print function, e.g. called myprint, using that mechanisms to encode output properly you can simply replace print with myprint whereever necessary without making the whole code look ugly.

3. Reset the output encoding globally at the begin of the software:

   The page http://www.macfreek.nl/memory/Encoding_of_Python_stdout has a good summary what to do to change output encoding. Especially the section "StreamWriter Wrapper around Stdout" is interesting. Essentially it says to change the I/O encoding function like this:

   In Python 2:

   if sys.stdout.encoding != 'cp850':
     sys.stdout = codecs.getwriter('cp850')(sys.stdout, 'strict')
   if sys.stderr.encoding != 'cp850':
     sys.stderr = codecs.getwriter('cp850')(sys.stderr, 'strict')
   

   In Python 3:

   if sys.stdout.encoding != 'cp850':
     sys.stdout = codecs.getwriter('cp850')(sys.stdout.buffer, 'strict')
   if sys.stderr.encoding != 'cp850':
     sys.stderr = codecs.getwriter('cp850')(sys.stderr.buffer, 'strict')
   

   If used in CGI outputting HTML you can replace 'strict' by 'xmlcharrefreplace' to get HTML encoded tags for non-printable characters.

   Feel free to modify the approaches, setting different encodings, .... Note that it still wont work to output non-specified data. So any data, input, texts must be correctly convertable into unicode:

   # -*- coding: utf-8 -*-
   import sys
   import codecs
   sys.stdout = codecs.getwriter("iso-8859-1")(sys.stdout, 'xmlcharrefreplace')
   print u"Stöcker"                # works
   print "Stöcker".decode("utf-8") # works
   print "Stöcker"                 # fails
   

It's a syntactically valid request, but not a satisfiable request. If you look further in that section you see:

If a syntactically valid byte-range-set includes at least one byte- range-spec whose first-byte-pos is less than the current length of the entity-body, or at least one suffix-byte-range-spec with a non- zero suffix-length, then the byte-range-set is satisfiable. Otherwise, the byte-range-set is unsatisfiable. If the byte-range-set is unsatisfiable, the server SHOULD return a response with a status of 416 (Requested range not satisfiable). Otherwise, the server SHOULD return a response with a status of 206 (Partial Content) containing the satisfiable ranges of the entity-body.

So I think in your example, the server should return a 416 since it's not a valid byte range for that file.

Another solution I ran across tonight, which worked for my needs, was to add box-sizing attributes:

-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;

These attributes force the border to be part of the box model's width and height and correct the issue as well.

According to caniuse.com » box-sizing, box-sizing is supported in IE8+.

If you're using LESS or Sass there is a Bootstrap mixin for this.

LESS:

.box-sizing(border-box);

Sass:

@include box-sizing(border-box);

Use Console.Write instead, so there's no newline written:

Console.Write("What is your name? ");
var name = Console.ReadLine();

I wondered this myself for a while. Without setters how does AngularJS notice changes to the $scope object? Does it poll them?

What it actually does is this: Any "normal" place you modify the model was already called from the guts of AngularJS, so it automatically calls $apply for you after your code runs. Say your controller has a method that's hooked up to ng-click on some element. Because AngularJS wires the calling of that method together for you, it has a chance to do an $apply in the appropriate place. Likewise, for expressions that appear right in the views, those are executed by AngularJS so it does the $apply.

When the documentation talks about having to call $apply manually for code outside of AngularJS, it's talking about code which, when run, doesn't stem from AngularJS itself in the call stack.

Add:

using System.Linq;

to the top of your file.

And then:

Car[] carList = ...
var carMake = 
    from item in carList
    where item.Model == "bmw" 
    select item.Make;

or if you prefer the fluent syntax:

var carMake = carList
    .Where(item => item.Model == "bmw")
    .Select(item => item.Make);

Things to pay attention to:

• The usage of item.Make in the select clause instead if s.Make as in your code.
• You have a whitespace between item and .Model in your where clause

You could use str.split to do this.

s = "<alpha.Customer[cus_Y4o9qMEZAugtnW] active_card=<alpha.AlphaObject[card]\
 ...>, created=1324336085, description='Customer for My Test App',\
 livemode=False>"
val = s.split('[', 1)[1].split(']')[0]

Then we have:

>>> val
'cus_Y4o9qMEZAugtnW'

I find a nice and tidy Wave game engine few days ago. It uses C# and have Windows Phone and Windows Store converters as well which makes it a great replacement of XNA for me

char is a primitive type, and it can hold a single character. String is instead a reference type, thus a full-blown object.

echo 0.0.0.0 websitename.com >> %WINDIR%\System32\Drivers\Etc\Hosts

the >> appends the output of echo to the file.

Note that there are two reasons this might not work like you want it to. You may be aware of these, but I mention them just in case.

First, it won't affect a web browser, for example, that already has the current, "real" IP address resolved. So, it won't always take effect right away.

Second, it requires you to add an entry for every host name on a domain; just adding websitename.com will not block www.websitename.com, for example.

<input type="file" @change="onFileChange" class="input upload-input" ref="inputFile"/>

onFileChange(e) {
    //upload file and then delete it from input 
    self.$refs.inputFile.value = ''
}

http://api.jquery.com/category/events/form-events/

http://api.jquery.com/category/events/keyboard-events/

http://api.jquery.com/category/events/mouse-events/

http://api.jquery.com/category/events/browser-events/

Below, I've listed some of the more common events, with comments about where they can be used (taken from jQuery documentation).

Mouse Events

(Any HTML element can receive these events.)

click

dblclick

mousedown

mousemove

mouseover

mouseout

mouseup

Keyboard Events

(These events can be attached to any element, but the event is only sent to the element that has the focus. Focusable elements can vary between browsers, but form elements can always get focus so are reasonable candidates for these event types.)

keydown

keypress

keyup

Form Events

blur (In recent browsers, the domain of the event has been extended to include all element types.)

change (This event is limited to <input> elements, <textarea> boxes and <select> elements.)

focus (This event is implicitly applicable to a limited set of elements, such as form elements (<input>, <select>, etc.) and links (<a href>). In recent browser versions, the event can be extended to include all element types by explicitly setting the element's tabindex property. An element can gain focus via keyboard commands, such as the Tab key, or by mouse clicks on the element.)

select (This event is limited to <input type="text"> fields and <textarea> boxes.)

submit (It can only be attached to <form> elements.)

What is the portable way to annotate a byte[] property?

It depends on what you want. JPA can persist a non annotated byte[]. From the JPA 2.0 spec:

11.1.6 Basic Annotation

The Basic annotation is the simplest type of mapping to a database column. The Basic annotation can be applied to a persistent property or instance variable of any of the following types: Java primitive, types, wrappers of the primitive types, java.lang.String, java.math.BigInteger, java.math.BigDecimal, java.util.Date, java.util.Calendar, java.sql.Date, java.sql.Time, java.sql.Timestamp, byte[], Byte[], char[], Character[], enums, and any other type that implements Serializable. As described in Section 2.8, the use of the Basic annotation is optional for persistent fields and properties of these types. If the Basic annotation is not specified for such a field or property, the default values of the Basic annotation will apply.

And Hibernate will map a it "by default" to a SQL VARBINARY (or a SQL LONGVARBINARY depending on the Column size?) that PostgreSQL handles with a bytea.

But if you want the byte[] to be stored in a Large Object, you should use a @Lob. From the spec:

11.1.24 Lob Annotation

A Lob annotation specifies that a persistent property or field should be persisted as a large object to a database-supported large object type. Portable applications should use the Lob annotation when mapping to a database Lob type. The Lob annotation may be used in conjunction with the Basic annotation or with the ElementCollection annotation when the element collection value is of basic type. A Lob may be either a binary or character type. The Lob type is inferred from the type of the persistent field or property and, except for string and character types, defaults to Blob.

And Hibernate will map it to a SQL BLOB that PostgreSQL handles with a oid .

Is this fixed in some recent version of hibernate?

Well, the problem is that I don't know what the problem is exactly. But I can at least say that nothing has changed since 3.5.0-Beta-2 (which is where a changed has been introduced)in the 3.5.x branch.

But my understanding of issues like HHH-4876, HHH-4617 and of PostgreSQL and BLOBs (mentioned in the javadoc of the PostgreSQLDialect) is that you are supposed to set the following property

hibernate.jdbc.use_streams_for_binary=false

if you want to use oid i.e. byte[] with @Lob (which is my understanding since VARBINARY is not what you want with Oracle). Did you try this?

As an alternative, HHH-4876 suggests using the deprecated PrimitiveByteArrayBlobType to get the old behavior (pre Hibernate 3.5).

This is an expansion to totem's answer. It does basically the same thing but the property matching is based on the serialized json object, not reflect the .net object. This is important if you're using [JsonProperty], using the CamelCasePropertyNamesContractResolver, or doing anything else that will cause the json to not match the .net object.

Usage is simple:

[KnownType(typeof(B))]
public class A
{
   public string Name { get; set; }
}

public class B : A
{
   public string LastName { get; set; }
}

Converter code:

/// <summary>
/// Use KnownType Attribute to match a divierd class based on the class given to the serilaizer
/// Selected class will be the first class to match all properties in the json object.
/// </summary>
public class KnownTypeConverter : JsonConverter {
    public override bool CanConvert( Type objectType ) {
        return System.Attribute.GetCustomAttributes( objectType ).Any( v => v is KnownTypeAttribute );
    }

    public override bool CanWrite {
        get { return false; }
    }

    public override object ReadJson( JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer ) {
        // Load JObject from stream
        JObject jObject = JObject.Load( reader );

        // Create target object based on JObject
        System.Attribute[ ] attrs = System.Attribute.GetCustomAttributes( objectType );  // Reflection. 

        // check known types for a match. 
        foreach( var attr in attrs.OfType<KnownTypeAttribute>( ) ) {
            object target = Activator.CreateInstance( attr.Type );

            JObject jTest;
            using( var writer = new StringWriter( ) ) {
                using( var jsonWriter = new JsonTextWriter( writer ) ) {
                    serializer.Serialize( jsonWriter, target );
                    string json = writer.ToString( );
                    jTest = JObject.Parse( json );
                }
            }

            var jO = this.GetKeys( jObject ).Select( k => k.Key ).ToList( );
            var jT = this.GetKeys( jTest ).Select( k => k.Key ).ToList( );

            if( jO.Count == jT.Count && jO.Intersect( jT ).Count( ) == jO.Count ) {
                serializer.Populate( jObject.CreateReader( ), target );
                return target;
            }
        }

        throw new SerializationException( string.Format( "Could not convert base class {0}", objectType ) );
    }

    public override void WriteJson( JsonWriter writer, object value, JsonSerializer serializer ) {
        throw new NotImplementedException( );
    }

    private IEnumerable<KeyValuePair<string, JToken>> GetKeys( JObject obj ) {
        var list = new List<KeyValuePair<string, JToken>>( );
        foreach( var t in obj ) {
            list.Add( t );
        }
        return list;
    }
}

Personally I prefer the join syntax as its makes it clearer that the tables are joined and how they are joined. Try compare larger SQL queries where you selecting from 8 different tables and you have lots of filtering in the where. By using join syntax you separate out the parts where the tables are joined, to the part where you are filtering the rows.

You could try to split on (?<=\D)(?=\d)|(?<=\d)(?=\D), like:

str.split("(?<=\\D)(?=\\d)|(?<=\\d)(?=\\D)");

It matches positions between a number and not-a-number (in any order).

• (?<=\D)(?=\d) - matches a position between a non-digit (\D) and a digit (\d)
• (?<=\d)(?=\D) - matches a position between a digit and a non-digit.

Just a comment, as someone may find it useful - you can concatenate more than one string in one go:

>>> a='rabbit'
>>> b='fox'
>>> print '%s and %s' %(a,b)
rabbit and fox

it's just your own style,nothing a bad style code,and nothing a good style code,just difference our code with the others.

I had the same problem after upgrading the support library and none of the answers worked for me. Finally I solved downloading latest version of build tools and upgrading in build.gradle to buildToolsVersion "23.0.1"

You can mock out aw.Clear, either manually or using a testing framework like pymox. Manually, you'd do it using something like this:

class MyTest(TestCase):
  def testClear():
    old_clear = aw.Clear
    clear_calls = 0
    aw.Clear = lambda: clear_calls += 1
    aps.Request('nv2', aw)
    assert clear_calls == 1
    aw.Clear = old_clear

Using pymox, you'd do it like this:

class MyTest(mox.MoxTestBase):
  def testClear():
    aw = self.m.CreateMock(aps.Request)
    aw.Clear()
    self.mox.ReplayAll()
    aps.Request('nv2', aw)

Update July 2012 (git 1.7.12+)

You now can rebase all commits up to root, and select the second commit Y to be squashed with the first X.

git rebase -i --root master

pick sha1 X
squash sha1 Y
pick sha1 Z

git rebase [-i] --root $tip

This command can now be used to rewrite all the history leading from "$tip" down to the root commit.

See commit df5df20c1308f936ea542c86df1e9c6974168472 on GitHub from Chris Webb (arachsys).

Original answer (February 2009)

I believe you will find different recipes for that in the SO question "How do I combine the first two commits of a git repository?"

Charles Bailey provided there the most detailed answer, reminding us that a commit is a full tree (not just diffs from a previous states).
And here the old commit (the "initial commit") and the new commit (result of the squashing) will have no common ancestor.
That mean you can not "commit --amend" the initial commit into new one, and then rebase onto the new initial commit the history of the previous initial commit (lots of conflicts)

(That last sentence is no longer true with git rebase -i --root <aBranch>)

Rather (with A the original "initial commit", and B a subsequent commit needed to be squashed into the initial one):

1. Go back to the last commit that we want to form the initial commit (detach HEAD):

   git checkout <sha1_for_B>
   

2. Reset the branch pointer to the initial commit, but leaving the index and working tree intact:

   git reset --soft <sha1_for_A>
   

3. Amend the initial tree using the tree from 'B':

   git commit --amend
   

4. Temporarily tag this new initial commit (or you could remember the new commit sha1 manually):

   git tag tmp
   

5. Go back to the original branch (assume master for this example):

   git checkout master
   

6. Replay all the commits after B onto the new initial commit:

   git rebase --onto tmp <sha1_for_B>
   

7. Remove the temporary tag:

   git tag -d tmp
   

That way, the "rebase --onto" does not introduce conflicts during the merge, since it rebases history made after the last commit (B) to be squashed into the initial one (which was A) to tmp (representing the squashed new initial commit): trivial fast-forward merges only.

That works for "A-B", but also "A-...-...-...-B" (any number of commits can be squashed into the initial one this way)

Is just casting the value returned by time()

#include <stdio.h>
#include <time.h>

int main(void) {
    printf("Timestamp: %d\n",(int)time(NULL));
    return 0;
}

what you want?

$ gcc -Wall -Wextra -pedantic -std=c99 tstamp.c && ./a.out
Timestamp: 1343846167

To get microseconds since the epoch, from C11 on, the portable way is to use

int timespec_get(struct timespec *ts, int base)

Unfortunately, C11 is not yet available everywhere, so as of now, the closest to portable is using one of the POSIX functions clock_gettime or gettimeofday (marked obsolete in POSIX.1-2008, which recommends clock_gettime).

The code for both functions is nearly identical:

#include <stdio.h>
#include <time.h>
#include <stdint.h>
#include <inttypes.h>

int main(void) {

    struct timespec tms;

    /* The C11 way */
    /* if (! timespec_get(&tms, TIME_UTC)) { */

    /* POSIX.1-2008 way */
    if (clock_gettime(CLOCK_REALTIME,&tms)) {
        return -1;
    }
    /* seconds, multiplied with 1 million */
    int64_t micros = tms.tv_sec * 1000000;
    /* Add full microseconds */
    micros += tms.tv_nsec/1000;
    /* round up if necessary */
    if (tms.tv_nsec % 1000 >= 500) {
        ++micros;
    }
    printf("Microseconds: %"PRId64"\n",micros);
    return 0;
}

I found that for an SPA HTML5Mode causes lots of 404 error problems, and it is not necessary to make $location.search work in this case. In my case I want to capture a URL query string parameter when a user comes to my site, regardless of which "page" they initially link to, AND be able to send them to that page once they log in. So I just capture all that stuff in app.run

$rootScope.$on('$stateChangeStart', function (e, toState, toParams, fromState, fromParams) {
    if (fromState.name === "") {
        e.preventDefault();
        $rootScope.initialPage = toState.name;
        $rootScope.initialParams = toParams;
        return;
    }
    if ($location.search().hasOwnProperty('role')) {
        $rootScope.roleParameter = $location.search()['role'];
    }
    ...
}

then later after login I can say $state.go($rootScope.initialPage, $rootScope.initialParams)

You could use the String Convert.ToBase64String(byte[]) to encode the byte array into a base64 string, then Byte[] Convert.FromBase64String(string) to convert the resulting string back into a byte array.

Use Array.prototype.concat.apply to handle multiple arrays' concatenation:

var resultArray = Array.prototype.concat.apply([], arrayOfArraysToConcat);

Example:

var a1 = [1, 2, 3],
    a2 = [4, 5],
    a3 = [6, 7, 8, 9];
Array.prototype.concat.apply([], [a1, a2, a3]); // [1, 2, 3, 4, 5, 6, 7, 8, 9]

I would have expected your syntax to work too. The problem arises because when you create new columns with the column-list syntax (df[[new1, new2]] = ...), pandas requires that the right hand side be a DataFrame (note that it doesn't actually matter if the columns of the DataFrame have the same names as the columns you are creating).

Your syntax works fine for assigning scalar values to existing columns, and pandas is also happy to assign scalar values to a new column using the single-column syntax (df[new1] = ...). So the solution is either to convert this into several single-column assignments, or create a suitable DataFrame for the right-hand side.

Here are several approaches that will work:

import pandas as pd
import numpy as np

df = pd.DataFrame({
    'col_1': [0, 1, 2, 3],
    'col_2': [4, 5, 6, 7]
})

Then one of the following:

1) Three assignments in one, using list unpacking:

df['column_new_1'], df['column_new_2'], df['column_new_3'] = [np.nan, 'dogs', 3]

2) DataFrame conveniently expands a single row to match the index, so you can do this:

df[['column_new_1', 'column_new_2', 'column_new_3']] = pd.DataFrame([[np.nan, 'dogs', 3]], index=df.index)

3) Make a temporary data frame with new columns, then combine with the original data frame later:

df = pd.concat(
    [
        df,
        pd.DataFrame(
            [[np.nan, 'dogs', 3]], 
            index=df.index, 
            columns=['column_new_1', 'column_new_2', 'column_new_3']
        )
    ], axis=1
)

4) Similar to the previous, but using join instead of concat (may be less efficient):

df = df.join(pd.DataFrame(
    [[np.nan, 'dogs', 3]], 
    index=df.index, 
    columns=['column_new_1', 'column_new_2', 'column_new_3']
))

5) Using a dict is a more "natural" way to create the new data frame than the previous two, but the new columns will be sorted alphabetically (at least before Python 3.6 or 3.7):

df = df.join(pd.DataFrame(
    {
        'column_new_1': np.nan,
        'column_new_2': 'dogs',
        'column_new_3': 3
    }, index=df.index
))

6) Use .assign() with multiple column arguments.

I like this variant on @zero's answer a lot, but like the previous one, the new columns will always be sorted alphabetically, at least with early versions of Python:

df = df.assign(column_new_1=np.nan, column_new_2='dogs', column_new_3=3)

7) This is interesting (based on https://stackoverflow.com/a/44951376/3830997), but I don't know when it would be worth the trouble:

new_cols = ['column_new_1', 'column_new_2', 'column_new_3']
new_vals = [np.nan, 'dogs', 3]
df = df.reindex(columns=df.columns.tolist() + new_cols)   # add empty cols
df[new_cols] = new_vals  # multi-column assignment works for existing cols

8) In the end it's hard to beat three separate assignments:

df['column_new_1'] = np.nan
df['column_new_2'] = 'dogs'
df['column_new_3'] = 3

Note: many of these options have already been covered in other answers: Add multiple columns to DataFrame and set them equal to an existing column, Is it possible to add several columns at once to a pandas DataFrame?, Add multiple empty columns to pandas DataFrame

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

Assuming that your table is called 'Table1' and the column you need is 'Column' you can try this:

for i = 1 to Range("Table1").Rows.Count
   Range("Table1[Column]")(i)="PHEV"
next i

objdump + gdb minimal runnable example

TL;DR:

• GDB can be used to find failing line, previously mentioned at: How do I analyze a program's core dump file with GDB when it has command-line parameters?
• the core file contains the CLI arguments, no need to pass them again
• objdump -s core can be used to dump memory in bulk

Now for the full educational test setup:

main.c

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

int myfunc(int i) {
    *(int*)(NULL) = i; /* line 7 */
    return i - 1;
}

int main(int argc, char **argv) {
    /* Setup some memory. */
    char data_ptr[] = "string in data segment";
    char *mmap_ptr;
    char *text_ptr = "string in text segment";
    (void)argv;
    mmap_ptr = (char *)malloc(sizeof(data_ptr) + 1);
    strcpy(mmap_ptr, data_ptr);
    mmap_ptr[10] = 'm';
    mmap_ptr[11] = 'm';
    mmap_ptr[12] = 'a';
    mmap_ptr[13] = 'p';
    printf("text addr: %p\n", text_ptr);
    printf("data addr: %p\n", data_ptr);
    printf("mmap addr: %p\n", mmap_ptr);

    /* Call a function to prepare a stack trace. */
    return myfunc(argc);
}

Compile, and run to generate core:

gcc -ggdb3 -std=c99 -Wall -Wextra -pedantic -o main.out main.c
ulimit -c unlimited
rm -f core
./main.out

Output:

text addr: 0x4007d4
data addr: 0x7ffec6739220
mmap addr: 0x1612010
Segmentation fault (core dumped)

GDB points us to the exact line where the segmentation fault happened, which is what most users want while debugging:

gdb -q -nh main.out core

then:

Reading symbols from main.out...done.
[New LWP 27479]
Core was generated by `./main.out'.
Program terminated with signal SIGSEGV, Segmentation fault.

#1  0x000000000040072b in main (argc=1, argv=0x7ffec6739328) at main.c:28

which points us directly to the buggy line 7.

CLI arguments are stored in the core file and don't need to be passed again

To answer the specific CLI argument questions, we see that if we change the cli arguments e.g. with:

rm -f core
./main.out 1 2

then this does get reflected in the previous bactrace without any changes in our commands:

Reading symbols from main.out...done.
[New LWP 21838]
Core was generated by `./main.out 1 2'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x0000564583cf2759 in myfunc (i=3) at main.c:7
7           *(int*)(NULL) = i; /* line 7 */
(gdb) bt
#0  0x0000564583cf2759 in myfunc (i=3) at main.c:7
#1  0x0000564583cf2858 in main (argc=3, argv=0x7ffcca4effa8) at main.c:2

So note how now argc=3. Therefore this must mean that the core file stores that information. I'm guessing it just stores it as the arguments of main, just like it stores the arguments of any other functions.

This makes sense if you consider that the core dump must be storing the entire memory and register state of the program, and so it has all the information needed to determine the value of function arguments on the current stack.

Less obvious is how to inspect the environment variables: How to get environment variable from a core dump Environment variables are also present in memory so the objdump does contain that information, but I'm not sure how to list all of them in one go conveniently, one by one as follows did work on my tests though:

p __environ[0]

Binutils analysis

By using binutils tools like readelf and objdump, we can bulk dump information contained in the core file such as the memory state.

Most/all of it must also be visible through GDB, but those binutils tools offer a more bulk approach which is convenient for certain use cases, while GDB is more convenient for a more interactive exploration.

First:

file core

tells us that the core file is actually an ELF file:

core: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from './main.out'

which is why we are able to inspect it more directly with usual binutils tools.

A quick look at the ELF standard shows that there is actually an ELF type dedicated to it:

Elf32_Ehd.e_type == ET_CORE

Further format information can be found at:

man 5 core

Then:

readelf -Wa core

gives some hints about the file structure. Memory appears to be contained in regular program headers:

Program Headers:
  Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align

and there is some more metadata present in a notes area, notably prstatus contains the PC:

objdump can easily dump all memory with:

objdump -s core

which contains:

which matches exactly with the stdout value in our run.

This was tested on Ubuntu 16.04 amd64, GCC 6.4.0, and binutils 2.26.1.

I run into that problem too! npm install is somewhat confusing and web posts keep bringing in the -d/--dev flags as if there is an explicit 'development' install mode.

• npm install will install both "dependencies" and "devDependencies"

• npm install --production will only install "dependencies"

• npm install --dev will only install "devDependencies"

In Java you can't. Interface has to do with methods and signature, it does not have to do with the internal state of an object -- that is an implementation question. And this makes sense too -- I mean, simply because certain attributes exist, it does not mean that they have to be used by the implementing class. getHeight could actually point to the width variable (assuming that the implementer is a sadist).

(As a note -- this is not true of all languages, ActionScript allows for declaration of pseudo attributes, and I believe C# does too)

Use java.sql.Timestamp.toString if you want to get fractional seconds in text representation. The difference betwen Timestamp from DB and Java Date is that DB precision is nanoseconds while Java Date precision is milliseconds.

If you like to remove last 5 characters, you can use:

path.substring(0,path.length() - 5)

( could contain off by one error ;) )

If you like to remove some variable string:

path.substring(0,path.lastIndexOf('yoursubstringtoremove));

(could also contain off by one error ;) )

Similar to @James answer, a more pythonic way can be:

fields = map(lambda x:x[0], cursor.description)
result = [dict(zip(fields,row))   for row in cursor.fetchall()]

You can get a single column with map over the result:

extensions = map(lambda x: x['ext'], result)

or filter results:

filter(lambda x: x['filesize'] > 1024 and x['filesize'] < 4096, result)

or accumulate values for filtered columns:

totalTxtSize = reduce(
        lambda x,y: x+y,
        filter(lambda x: x['ext'].lower() == 'txt', result)
)

Speaking as a mere mortal, I would stick with $str[0]. As far as I'm concerned, it's quicker to grasp the meaning of $str[0] at a glance than substr($str, 0, 1). This probably boils down to a matter of preference.

As far as performance goes, well, profile profile profile. :) Or you could peer into the PHP source code...

The schema object naming rules may also be of some use:

Following is the way to change the color of the left icon in edit text and set it in left side.

 Drawable img = getResources().getDrawable( R.drawable.user );
img.setBounds( 0, 0, 60, 60 );
mNameEditText.setCompoundDrawables(img,null, null, null);

int color = ContextCompat.getColor(this, R.color.blackColor);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    DrawableCompat.setTint(img, color);

} else {
    img.mutate().setColorFilter(color, PorterDuff.Mode.SRC_IN);
}

set hlsearch

maybe ?

I recommend Dowser. It is very easy to setup, and you need zero changes to your code. You can view counts of objects of each type through time, view list of live objects, view references to live objects, all from the simple web interface.

# memdebug.py

import cherrypy
import dowser

def start(port):
    cherrypy.tree.mount(dowser.Root())
    cherrypy.config.update({
        'environment': 'embedded',
        'server.socket_port': port
    })
    cherrypy.server.quickstart()
    cherrypy.engine.start(blocking=False)

You import memdebug, and call memdebug.start. That's all.

I haven't tried PySizer or Heapy. I would appreciate others' reviews.

UPDATE

The above code is for CherryPy 2.X, CherryPy 3.X the server.quickstart method has been removed and engine.start does not take the blocking flag. So if you are using CherryPy 3.X

# memdebug.py

import cherrypy
import dowser

def start(port):
    cherrypy.tree.mount(dowser.Root())
    cherrypy.config.update({
        'environment': 'embedded',
        'server.socket_port': port
    })
    cherrypy.engine.start()

Unfortunately the accepted answer did not work for me. As a temporary workaround you could also use verify=False when connecting to the secure website.

From Python Requests throwing up SSLError

requests.get('https://example.com', verify=True)

This is are other ways of printing empty lines in python

# using \n after the string creates an empty line after this string is passed to the the terminal.
print("We need to put about", average_passengers_per_car, "in each car. \n") 
print("\n") #prints 2 empty lines 
print() #prints 1 empty line 

The java documentation suggests to make use of Calendar class instead of this deprecated way Here is the sample code to set up the calendar object

Calendar calendar = Calendar.getInstance();
calendar.setTime(new Date());

Here is the sample code to get the year, month, etc.

System.out.println(calendar.get(Calendar.YEAR));
System.out.println(calendar.get(Calendar.MONTH));

Calendar also has support for many other useful information like, TIME, DAY_OF_MONTH, etc. Here the documentation listing all of them Please note that the month are 0 based. January is 0th month.

I'd prefer to exit with double tap on the back button than with an exit Dialog.

In this solution, it show a toast when go back for the first time, warning that another back press will close the App. In this example less than 4 seconds.

private Toast toast;
private long lastBackPressTime = 0;

@Override
public void onBackPressed() {
  if (this.lastBackPressTime < System.currentTimeMillis() - 4000) {
    toast = Toast.makeText(this, "Press back again to close this app", 4000);
    toast.show();
    this.lastBackPressTime = System.currentTimeMillis();
  } else {
    if (toast != null) {
    toast.cancel();
  }
  super.onBackPressed();
 }
}

I'm a little out of touch with the details of how MySQL deals with nulls, but here's two things to try:

SELECT * FROM match WHERE id NOT IN 
    ( SELECT id FROM email WHERE id IS NOT NULL) ;

SELECT
    m.*
FROM
    match m
    LEFT OUTER JOIN email e ON
        m.id = e.id
        AND e.id IS NOT NULL
WHERE
    e.id IS NULL

The second query looks counter intuitive, but it does the join condition and then the where condition. This is the case where joins and where clauses are not equivalent.

I got the same exception while deleting a record by Id that does not exists at all. So check that record you are updating/Deleting actually exists in DB

You could use

SHOW TABLES;

Then get the columns in those tables (in a loop) with

SHOW COLUMNS FROM table;

and then with that info create many many queries which you can also UNION if you need.

But this is extremely heavy on the database. Specially if you are doing a LIKE search.

I recently struggled with this issue for 3 days. How the client is sending the request might not be the cause, the server might not be configured to handle multipart requests. This is what I had to do to get it working:

pom.xml - Added commons-fileupload dependency (download and add the jar to your project if you are not using dependency management such as maven)

<dependency>
  <groupId>commons-fileupload</groupId>
  <artifactId>commons-fileupload</artifactId>
  <version>${commons-version}</version>
</dependency>

web.xml - Add multipart filter and mapping

<filter>
  <filter-name>multipartFilter</filter-name>
  <filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>multipartFilter</filter-name>
  <url-pattern>/springrest/*</url-pattern>
</filter-mapping>

app-context.xml - Add multipart resolver

<beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <beans:property name="maxUploadSize">
        <beans:value>10000000</beans:value>
    </beans:property>
</beans:bean>

Your Controller

@RequestMapping(value=Constants.REQUEST_MAPPING_ADD_IMAGE, method = RequestMethod.POST, produces = { "application/json"})
public @ResponseBody boolean saveStationImage(
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_FILE) MultipartFile file,
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_URI) String imageUri, 
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_TYPE) String imageType, 
        @RequestParam(value = Constants.MONGO_FIELD_STATION_ID) String stationId) {
    // Do something with file
    // Return results
}

Your client

public static Boolean updateStationImage(StationImage stationImage) {
    if(stationImage == null) {
        Log.w(TAG + ":updateStationImage", "Station Image object is null, returning.");
        return null;
    }

    Log.d(TAG, "Uploading: " + stationImage.getImageUri());
    try {
        RestTemplate restTemplate = new RestTemplate();
        FormHttpMessageConverter formConverter = new FormHttpMessageConverter();
        formConverter.setCharset(Charset.forName("UTF8"));
        restTemplate.getMessageConverters().add(formConverter);
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

        restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());

        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.setAccept(Collections.singletonList(MediaType.parseMediaType("application/json")));

        MultiValueMap<String, Object> parts = new LinkedMultiValueMap<String, Object>();

        parts.add(Constants.STATION_PROFILE_IMAGE_FILE, new FileSystemResource(stationImage.getImageFile()));
        parts.add(Constants.STATION_PROFILE_IMAGE_URI, stationImage.getImageUri());
        parts.add(Constants.STATION_PROFILE_IMAGE_TYPE, stationImage.getImageType());
        parts.add(Constants.FIELD_STATION_ID, stationImage.getStationId());

        return restTemplate.postForObject(Constants.REST_CLIENT_URL_ADD_IMAGE, parts, Boolean.class);
    } catch (Exception e) {
        StringWriter sw = new StringWriter();
        e.printStackTrace(new PrintWriter(sw));

        Log.e(TAG + ":addStationImage", sw.toString());
    }

    return false;
}

That should do the trick. I added as much information as possible because I spent days, piecing together bits and pieces of the full issue, I hope this will help.

Just add !important tag to all css elements in Paolo's answer! Works fine for me JQM+phonegap

EXAMPLE:

Put webpack -v into your package.json:

{
  "name": "js",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "webpack -v",
    "dev": "webpack --watch"
  }
}

Then enter in the console:

npm run build

Expected output should look like:

> npm run build

> [email protected] build /home/user/repositories/myproject/js
> webpack -v

4.42.0

For some reason, you're re-instantiating the form after you check is_valid(). Forms only get a cleaned_data attribute when is_valid() has been called, and you haven't called it on this new, second instance.

Just get rid of the second form = SearchForm(request.POST) and all should be well.

Hopefully this method from the UITableViewDelegate protocol will get you started:

Objective-C:

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{
  UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
  if (section == integerRepresentingYourSectionOfInterest)
     [headerView setBackgroundColor:[UIColor redColor]];
  else 
     [headerView setBackgroundColor:[UIColor clearColor]];
  return headerView;
}

Swift:

func tableView(_ tableView: UITableView!, viewForHeaderInSection section: Int) -> UIView!
{
  let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))
  if (section == integerRepresentingYourSectionOfInterest) {
    headerView.backgroundColor = UIColor.redColor()
  } else {
    headerView.backgroundColor = UIColor.clearColor()
  }
  return headerView
}

Updated 2017:

Swift 3:

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
    {
        let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))
        if (section == integerRepresentingYourSectionOfInterest) {
            headerView.backgroundColor = UIColor.red
        } else {
            headerView.backgroundColor = UIColor.clear
        }
        return headerView
    }

Replace [UIColor redColor] with whichever UIColor you would like. You may also wish to adjust the dimensions of headerView.

C does not really have multi-dimensional arrays, but there are several ways to simulate them. The way to pass such arrays to a function depends on the way used to simulate the multiple dimensions:

1) Use an array of arrays. This can only be used if your array bounds are fully determined at compile time, or if your compiler supports VLA's:

#define ROWS 4
#define COLS 5

void func(int array[ROWS][COLS])
{
  int i, j;

  for (i=0; i<ROWS; i++)
  {
    for (j=0; j<COLS; j++)
    {
      array[i][j] = i*j;
    }
  }
}

void func_vla(int rows, int cols, int array[rows][cols])
{
  int i, j;

  for (i=0; i<rows; i++)
  {
    for (j=0; j<cols; j++)
    {
      array[i][j] = i*j;
    }
  }
}

int main()
{
  int x[ROWS][COLS];

  func(x);
  func_vla(ROWS, COLS, x);
}

2) Use a (dynamically allocated) array of pointers to (dynamically allocated) arrays. This is used mostly when the array bounds are not known until runtime.

void func(int** array, int rows, int cols)
{
  int i, j;

  for (i=0; i<rows; i++)
  {
    for (j=0; j<cols; j++)
    {
      array[i][j] = i*j;
    }
  }
}

int main()
{
  int rows, cols, i;
  int **x;

  /* obtain values for rows & cols */

  /* allocate the array */
  x = malloc(rows * sizeof *x);
  for (i=0; i<rows; i++)
  {
    x[i] = malloc(cols * sizeof *x[i]);
  }

  /* use the array */
  func(x, rows, cols);

  /* deallocate the array */
  for (i=0; i<rows; i++)
  {
    free(x[i]);
  }
  free(x);
}

3) Use a 1-dimensional array and fixup the indices. This can be used with both statically allocated (fixed-size) and dynamically allocated arrays:

void func(int* array, int rows, int cols)
{
  int i, j;

  for (i=0; i<rows; i++)
  {
    for (j=0; j<cols; j++)
    {
      array[i*cols+j]=i*j;
    }
  }
}

int main()
{
  int rows, cols;
  int *x;

  /* obtain values for rows & cols */

  /* allocate the array */
  x = malloc(rows * cols * sizeof *x);

  /* use the array */
  func(x, rows, cols);

  /* deallocate the array */
  free(x);
}

4) Use a dynamically allocated VLA. One advantage of this over option 2 is that there is a single memory allocation; another is that less memory is needed because the array of pointers is not required.

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

extern void func_vla(int rows, int cols, int array[rows][cols]);
extern void get_rows_cols(int *rows, int *cols);
extern void dump_array(const char *tag, int rows, int cols, int array[rows][cols]);

void func_vla(int rows, int cols, int array[rows][cols])
{
    for (int i = 0; i < rows; i++)
    {
        for (int j = 0; j < cols; j++)
        {
            array[i][j] = (i + 1) * (j + 1);
        }
    }
}

int main(void)
{
    int rows, cols;

    get_rows_cols(&rows, &cols);

    int (*array)[cols] = malloc(rows * cols * sizeof(array[0][0]));
    /* error check omitted */

    func_vla(rows, cols, array);
    dump_array("After initialization", rows, cols, array);

    free(array);
    return 0;
}

void dump_array(const char *tag, int rows, int cols, int array[rows][cols])
{
    printf("%s (%dx%d):\n", tag, rows, cols);
    for (int i = 0; i < rows; i++)
    {
        for (int j = 0; j < cols; j++)
            printf("%4d", array[i][j]);
        putchar('\n');
    }
}

void get_rows_cols(int *rows, int *cols)
{
    srand(time(0));           // Only acceptable because it is called once
    *rows = 5 + rand() % 10;
    *cols = 3 + rand() % 12;
}

(See srand() — why call it only once?.)

If somehow you want a simple, yet different solution, you can use the {**dict} syntax:

from collections import OrderedDict

ordered = OrderedDict([('method', 'constant'), ('data', '1.225')])
regular = {**ordered}

I'm new to java and I'm taking up your question as a challenge to improve my knowledge as well so please forgive me if this does not answer your question well:

import java.util.ArrayList;
import java.util.List;

public class PalindromeRecursiveBoolean {

    public static boolean isPalindrome(String str) {

        str = str.toUpperCase();
        char[] strChars = str.toCharArray();

        List<Character> word = new ArrayList<>();
        for (char c : strChars) {
            word.add(c);
        }

        while (true) {
            if ((word.size() == 1) || (word.size() == 0)) {
                return true;
            }
            if (word.get(0) == word.get(word.size() - 1)) {
                word.remove(0);
                word.remove(word.size() - 1);
            } else {
                return false;

            }

        }
    }
}

1. If the string is made of no letters or just one letter, it is a palindrome.
2. Otherwise, compare the first and last letters of the string.
   • If the first and last letters differ, then the string is not a palindrome
   • Otherwise, the first and last letters are the same. Strip them from the string, and determine whether the string that remains is a palindrome. Take the answer for this smaller string and use it as the answer for the original string then repeat from 1.

The only string manipulation is changing the string to uppercase so that you can enter something like 'XScsX'

Here is an additional answer that was also great help for me to understand how it worked : http://www.javacodegeeks.com/2013/07/spring-bean-and-propertyplaceholderconfigurer.html

any BeanFactoryPostProcessor beans have to be declared with a static, modifier

@Configuration
@PropertySource("classpath:root/test.props")
public class SampleConfig {
 @Value("${test.prop}")
 private String attr;
 @Bean
 public SampleService sampleService() {
  return new SampleService(attr);
 }

 @Bean
 public static PropertySourcesPlaceholderConfigurer placeHolderConfigurer() {
  return new PropertySourcesPlaceholderConfigurer();
 }
}

i think it's just the debugger making it simple. Note that a case and "if list" are not ultimately the same. There is is a reason why case blocks normally end with "break". The case stmt actually looks something like this when broken down in assembly.

if myObject.GetType() == type of Car
    GOTO START_CAR
else if myObject.GetType() == type of Bike
    GOTO START_BIKE

LABEL START_CAR
//do something car     
GOTO END

LABEL START_BIKE
//do something bike  
GOTO END

LABEL END

If you don't have the break, then the case blocks would be missing the "GOTO END" stmts, and in fact if you landed in the "car" case you'd actually run both sections

//do something car     
//do something bike  
GOTO END

Although I take the risk of not being popular I say they are not useful nowadays.

I think they were well intended and useful in the past when for example DELETE told the server to delete the resource found at supplied URL and PUT (with its sibling PATCH) told the server to do update in an idempotent manner.

Things evolved and URLs became virtual (see url rewriting for example) making resources lose their initial meaning of real folder/subforder/file and so, CRUD action verbs covered by HTTP protocol methods (GET, POST, PUT/PATCH, DELETE) lost track.

Let's take an example:

• /api/entity/list/{id} vs GET /api/entity/{id}
• /api/entity/add/{id} vs POST /api/entity
• /api/entity/edit/{id} vs PUT /api/entity/{id}
• /api/entity/delete/{id} vs DELETE /api/entity/{id}

On the left side is not written the HTTP method, essentially it doesn't matter (POST and GET are enough) and on the right side appropriate HTTP methods are used.

Right side looks elegant, clean and professional. Imagine now you have to maintain a code that's been using the elegant API and you have to search where deletion call is done. You'll search for "api/entity" and among results you'll have to see which one is doing DELETE. Or even worse, you have a junior programmer which by mistake switched PUT with DELETE and as URL is the same shit happened.

In my opinion putting the action verb in the URL has advantages over using the appropriate HTTP method for that action even if it's not so elegant. If you want to see where delete call is made you just have to search for "api/entity/delete" and you'll find it straight away.

Building an API without the whole HTTP array of methods makes it easier to be consumed and maintained afterwards

X = np.array(X, dtype=float)

You can use this to convert to array of float in python 3.7.6

If you want to get one element by row index and column name, you can do it just like df['b'][0]. It is as simple as you can imagine.

Or you can use df.ix[0,'b'] - mixed usage of index and label.

Note: Since v0.20, ix has been deprecated in favour of loc / iloc.

I like Lift ;-)

Play is my second choice for Scala-friendly web frameworks.

Wicket is my third choice.

If you read the link you shared, the accepted answer is:

You cannot post pictures to Instagram via the API.

Hopefully you have some luck here.

Some of it is possible, specifically accessing subtotals:

"In Excel 2010+, you can right-click on the values and select Show Values As –> % of Parent Row Total." (or % of Parent Column Total)

• And make sure the field in question is a number field that can be summed, it does not work for text fields for which only count is normally informative.

It's my experience that it's actually better to just deal with the orientation changes properly instead of trying to shoehorn a non-default behavior.

You should save the image that's currently being displayed in onSaveInstanceState() and restore it properly when your application runs through onCreate() again.

If you need two or more dealings with the filter, is possible to chain them:

{{ value | decimalRound: 2 | currencySimbol: 'U$' }} 
// 11.1111 becomes U$ 11.11

this is also fix for "httponlycookies in config" security issue

Try this :

@Override
protected void onPause() {
    super.onPause();
    if (getSupportFragmentManager().findFragmentByTag("MyFragment") != null)
        getSupportFragmentManager().findFragmentByTag("MyFragment").setRetainInstance(true);
}

@Override

    super.onResume();
    if (getSupportFragmentManager().findFragmentByTag("MyFragment") != null)
        getSupportFragmentManager().findFragmentByTag("MyFragment").getRetainInstance();
}

Hope this will help.

Also you can write this to activity tag in menifest file :

  android:configChanges="orientation|screenSize"

Good luck !!!

This may be an old post but I realized there is nothing to be returned from the php and your success function does not have input like as follows, success:function(e){}. I hope that helps you.

write this code

scp -r -o "ForwardAgent=yes" /Users/pengge/11.vim [email protected]:/root/

If you have a SSH key with access to the destination server and the source server does not, adding -o "ForwardAgent=yes" will allow you to forward your SSH agent to the source server so that it can use your SSH key to connect to the destination server.

[Offering a somewhat more descriptive answer than the answer provided by @Ajni.]

This can also be achieved using LINQ fluent syntax:

var list = ctn.Items
    .Where(t=> t.DeliverySelection == true && t.Delivery.SentForDelivery == null)
    .OrderBy(t => t.Delivery.SubmissionDate)
    .Take(5);

Note that each method (Where, OrderBy, Take) that appears in this LINQ statement takes a lambda expression as an argument. Also note that the documentation for Enumerable.Take begins with:

Returns a specified number of contiguous elements from the start of a sequence.

Easy solution would be to apply : idxmax() function to get indices of rows with max values. This would filter out all the rows with max value in the group.

In [365]: import pandas as pd

In [366]: df = pd.DataFrame({
'sp' : ['MM1', 'MM1', 'MM1', 'MM2', 'MM2', 'MM2', 'MM4', 'MM4','MM4'],
'mt' : ['S1', 'S1', 'S3', 'S3', 'S4', 'S4', 'S2', 'S2', 'S2'],
'val' : ['a', 'n', 'cb', 'mk', 'bg', 'dgb', 'rd', 'cb', 'uyi'],
'count' : [3,2,5,8,10,1,2,2,7]
})

In [367]: df                                                                                                       
Out[367]: 
   count  mt   sp  val
0      3  S1  MM1    a
1      2  S1  MM1    n
2      5  S3  MM1   cb
3      8  S3  MM2   mk
4     10  S4  MM2   bg
5      1  S4  MM2  dgb
6      2  S2  MM4   rd
7      2  S2  MM4   cb
8      7  S2  MM4  uyi


### Apply idxmax() and use .loc() on dataframe to filter the rows with max values:
In [368]: df.loc[df.groupby(["sp", "mt"])["count"].idxmax()]                                                       
Out[368]: 
   count  mt   sp  val
0      3  S1  MM1    a
2      5  S3  MM1   cb
3      8  S3  MM2   mk
4     10  S4  MM2   bg
8      7  S2  MM4  uyi

### Just to show what values are returned by .idxmax() above:
In [369]: df.groupby(["sp", "mt"])["count"].idxmax().values                                                        
Out[369]: array([0, 2, 3, 4, 8])

Below code disables ListViewItem row selection and also allows to add padding, margin etc.

  </ListView.ItemContainerStyle> 

Using Alamofire worked out for me on Swift 3:

Step 1:

Integrate using pods.

pod 'Alamofire', '~> 4.4'

pod 'AlamofireImage', '~> 3.3'

Step 2:

import AlamofireImage

import Alamofire

Step 3:

Alamofire.request("https://httpbin.org/image/png").responseImage { response in

if let image = response.result.value {
    print("image downloaded: \(image)")
self.myImageview.image = image
}
}

This happened to me after I copy migrated an existing website to WP Engine and forgot to do one thing required by WP Engine:

Update the WordPress core installation of the site that is being copied to the latest version.

So here was the problem then:

My old site that I was copying from another server to WP Engine had version 4.0. However, when you copy an existing site to WP Engine, you don't copy the WordPress core files, you only copy the contents of wp-content and the state (or snapshot) of the existing database. So the state of the database for my existing site was for an installation running WP 4.0. Nevertheless, when you create a new WordPress install on WP Engine, that install is created with the latest version of WordPress, which, at the time happened to be version 4.0.1, so that means the core files on the destination (WP Engine) were for a 4.0.1 installation but the database snapshot I was gonna import into WP Engine was for version 4.0. So when I overwrote the default WP Engine database with the import of the copy the database of my old site, I got the redirection error to the install script.

So to fix it, I just logged into the WordPress admin site of the site on WP Engine, made sure to reset the file permissions (by clicking the blue button), which, you sometimes have to do on WP Engine, and then re-installed the WordPress core, which, basically updates your database so that internally the db state was for a WordPress 4.0.1 install and the core files also match the version.

Took me a while to figure out what was going on.

If you need to run request as the current user from desktop application use CredentialCache.DefaultCredentials (see on MSDN).

Your code looks fine if you need to run a request from server side code or under a different user.

Please note that you should be careful when storing passwords - consider using the SecureString version of the constructor.

I recommend initializing variables in constructors. That's why they exist: to ensure your objects are constructed (initialized) properly.

Either way will work, and it's a matter of style, but I prefer constructors for member initialization.

Another way to toggle:

- (IBAction)signOnClick:(id)sender
{
    if ([_signOnButton.titleLabel.text isEqualToString:@"Sign off"])
    {
        [sender setTitle:@"Sign on" forState:UIControlStateNormal];
    }
    else
    {
        [sender setTitle:@"Sign off" forState:UIControlStateNormal];
    }
}

Using pure Javascript:

Don't need to pass this to the SomeDeleteRowFunction():

<td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction()"></td>

The onclick function:

function SomeDeleteRowFunction() {
      // event.target will be the input element.
      var td = event.target.parentNode; 
      var tr = td.parentNode; // the row to be removed
      tr.parentNode.removeChild(tr);
}

You should use maven surefire plugin to run unit tests and maven failsafe plugin to run integration tests.

Please follow below if you wish to toggle the execution of these tests using flags.

Maven Configuration

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <skipTests>${skipUnitTests}</skipTests>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-failsafe-plugin</artifactId>

                <includes>
                    <include>**/*IT.java</include>
                </includes>
                <skipTests>${skipIntegrationTests}</skipTests>
            </configuration>
            <executions>
                <execution>

                        <goal>integration-test</goal>
                        <goal>verify</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

        <properties>
            <skipTests>false</skipTests>
            <skipUnitTests>${skipTests}</skipUnitTests>
            <skipIntegrationTests>${skipTests}</skipIntegrationTests>
        </properties>

So, tests will be skipped or switched according to below flag rules:

Tests can be skipped by below flags:

• -DskipTests skips both unit and integration tests
• -DskipUnitTests skips unit tests but executes integration tests
• -DskipIntegrationTests skips integration tests but executes unit tests

Running Tests

Run below to execute only Unit Tests

mvn clean test

You can execute below command to run the tests (both unit and integration)

mvn clean verify

In order to run only Integration Tests, follow

mvn failsafe:integration-test

Or skip unit tests

mvn clean install -DskipUnitTests

Also, in order to skip integration tests during mvn install, follow

mvn clean install -DskipIntegrationTests

You can skip all tests using

mvn clean install -DskipTests

Use this syntax for VB.NET 2005/2008 compatibility:

Dim theVar As New List(Of String)(New String() {"one", "two", "three"})

Although the VB.NET 2010 syntax is prettier.

It works far better this way (preserving responsiveness):

  <!-- somewhere deep start -->
  <div class="row">
    <div class="center-block col-md-4" style="float: none; background-color: grey">
      Hi there!
    </div>
  </div>
  <!-- somewhere deep end -->

Is there any way to access to the $VAR by just executing export.bash without sourcing it ?

Quick answer: No.

But there are several possible workarounds.

The most obvious one, which you've already mentioned, is to use source or . to execute the script in the context of the calling shell:

$ cat set-vars1.sh 
export FOO=BAR
$ . set-vars1.sh 
$ echo $FOO
BAR

Another way is to have the script, rather than setting an environment variable, print commands that will set the environment variable:

$ cat set-vars2.sh
#!/bin/bash
echo export FOO=BAR
$ eval "$(./set-vars2.sh)"
$ echo "$FOO"
BAR

A third approach is to have a script that sets your environment variable(s) internally and then invokes a specified command with that environment:

$ cat set-vars3.sh
#!/bin/bash
export FOO=BAR
exec "$@"
$ ./set-vars3.sh printenv | grep FOO
FOO=BAR

This last approach can be quite useful, though it's inconvenient for interactive use since it doesn't give you the settings in your current shell (with all the other settings and history you've built up).

You should be able to access the document in the IFRAME using the following code:

document.getElementById('myframe').contentWindow.document

However, you will not be able to do this if the page in the frame is loaded from a different domain (such as google.com). THis is because of the browser's Same Origin Policy.

Some thoughts:

• jQuery is a JavaScript library, not a language. So, JavaScript arrays look something like this:

  var someNumbers = [1, 2, 3, 4, 5];
  

• { pageNo: $(this).text(), sortBy: $("#sortBy").val()} is a map of key to value. If you want an array of the keys or values, you can do something like this:

  var keys = [];
  var values = [];
  
  var object = { pageNo: $(this).text(), sortBy: $("#sortBy").val()};
  $.each(object, function(key, value) {
      keys.push(key);
      values.push(value);
  });
  

• objects in JavaScript are incredibly flexible. If you want to create an object {foo: 1}, all of the following work:

  var obj = {foo: 1};
  
  var obj = {};
  obj['foo'] = 1;
  
  var obj = {};
  obj.foo = 1;
  

To wrap up, do you want this?

var data = {};
// either way of changing data will work:
data.pageNo = $(this).text();
data['sortBy'] = $("#sortBy").val();

$("#results").load("jquery-routing.php", data);

There are several places colon is used in Java code:

1) Jump-out label (Tutorial):

label: for (int i = 0; i < x; i++) {
    for (int j = 0; j < i; j++) {
        if (something(i, j)) break label; // jumps out of the i loop
    }
} 
// i.e. jumps to here

2) Ternary condition (Tutorial):

int a = (b < 4)? 7: 8; // if b < 4, set a to 7, else set a to 8

3) For-each loop (Tutorial):

String[] ss = {"hi", "there"}
for (String s: ss) {
    print(s); // output "hi" , and "there" on the next iteration
}

4) Assertion (Guide):

int a = factorial(b);
assert a >= 0: "factorial may not be less than 0"; // throws an AssertionError with the message if the condition evaluates to false

5) Case in switch statement (Tutorial):

switch (type) {
    case WHITESPACE:
    case RETURN:
        break;
    case NUMBER:
        print("got number: " + value);
        break;
    default:
        print("syntax error");
}

6) Method references (Tutorial)

class Person {
   public static int compareByAge(Person a, Person b) {
       return a.birthday.compareTo(b.birthday);
   }}
}

Arrays.sort(persons, Person::compareByAge);

Just use the modulus

loop through the list and run the following on each item

if(num % 2 == 0)
{
  //is even
}
else
{
  //is odd
}

Alternatively if you want to know if all are even you can do something like this:

bool allAreEven = lst.All(x => x % 2 == 0);

For primitives and Strings:

/** The empty String. */
const val EMPTY_STRING = ""

For other cases:

/** The empty array of Strings. */
@JvmField val EMPTY_STRING_ARRAY = arrayOfNulls<String>(0)

If you're only running the commands in one shot then you can just use subprocess.check_output convenience function:

def subprocess_cmd(command):
    output = subprocess.check_output(command, shell=True)
    print output

As we recently posted on the React blog, in the vast majority of cases you don't need getDerivedStateFromProps at all.

If you just want to compute some derived data, either:

1. Do it right inside render
2. Or, if re-calculating it is expensive, use a memoization helper like memoize-one.

Here's the simplest "after" example:

import memoize from "memoize-one";

class ExampleComponent extends React.Component {
  getDerivedData = memoize(computeDerivedState);

  render() {
    const derivedData = this.getDerivedData(this.props.someValue);
    // ...
  }
}

Check out this section of the blog post to learn more.

You can also use a Subject and trigger its next() function from promise. See sample below:

Add code like below ( I used service )

class UserService {_x000D_
  private createUserSubject: Subject < any > ;_x000D_
_x000D_
  createUserWithEmailAndPassword() {_x000D_
    if (this.createUserSubject) {_x000D_
      return this.createUserSubject;_x000D_
    } else {_x000D_
      this.createUserSubject = new Subject < any > ();_x000D_
      firebase.auth().createUserWithEmailAndPassword(email,_x000D_
          password)_x000D_
        .then(function(firebaseUser) {_x000D_
          // do something to update your UI component_x000D_
          // pass user object to UI component_x000D_
          this.createUserSubject.next(firebaseUser);_x000D_
        })_x000D_
        .catch(function(error) {_x000D_
          // Handle Errors here._x000D_
          var errorCode = error.code;_x000D_
          var errorMessage = error.message;_x000D_
          this.createUserSubject.error(error);_x000D_
          // ..._x000D_
        });_x000D_
    }_x000D_
_x000D_
  }_x000D_
}

Create User From Component like below

class UserComponent {_x000D_
  constructor(private userService: UserService) {_x000D_
    this.userService.createUserWithEmailAndPassword().subscribe(user => console.log(user), error => console.log(error);_x000D_
    }_x000D_
  }

I am guessing you are trying to mix Asp code and JS code and at some point it's breaking or not excusing the binding calls correctly.

Perhaps you can try using a delegate instead. It will cut out the complexity of when to bind the click event.

An example would be:

$('body').delegate('.menu li','click',function(){
   var $li = $(this);

   var shouldAddClass = $li.find('a[href^="www.xyz.com/link1"]').length != 0;

   if(shouldAddClass){
       $li.addClass('active');
   }
});

See if that helps, it uses the Attribute Starts With Selector from jQuery.

Here is a sample jQuery implementation – thanks to gojomo's answer and utype's suggestion (+1 for both)

$(function(){
  //===================================================================
  // Special price strike-out text
  // Usage:
  //   Normally:    <span class='price'>$59</span>
  //   On special:  <span class='price' special='$29'>$59</span>
  //===================================================================
  $(".price[special]").each(function() {
    var originalPrice = $(this).text();
    $(this).html('<strike><span>' + originalPrice +'</span></strike> ' + $(this).attr('special'))
           .removeAttr('special')
           .addClass('special');
  });
});

The CSS for that could be

.price strike, .price.special { color: Red; }
.price strike span { color: Black; }

There are two ways to handle the situation where we do not want the index to be stored in csv file.

1. As others have stated you can use index=False while saving your
   dataframe to csv file.

   df.to_csv('file_name.csv',index=False)

2. Or you can save your dataframe as it is with an index, and while reading you just drop the column unnamed 0 containing your previous index.Simple!

   df.to_csv(' file_name.csv ')
df_new = pd.read_csv('file_name.csv').drop(['unnamed 0'],axis=1)

He want an elegant and proper solution try this small regex pattern matcher.

This is specifically for India.(First digit can't be zero and and then can be any 9 digits) return mobile.matches("[1-9][0-9]{9}");

Pattern Breakdown:-

[1-9] matches first digit and checks if number(integer) lies between(inclusive) 1 to 9 [0-9]{9} matches the same thing but {9} tells the pattern that it has to check for upcoming all 9 digits.

Now the {9} part may vary for different countries so you may have array which tells the number of digits allowed in phone number. Some countries also have significance for zero ahead of number, so you may have exception for those and design a separate regex patterns for those countries phone numbers.

To my experience it simply does not work, unless you are willing to wrap your <select> in some wrapper. But what you can do instead is to use background image SVG. E.g.

    .archive .options select.opt {
    -moz-appearance: none;
    -webkit-appearance: none;
    padding-right: 1.25EM;
    appearance: none;
    position: relative;
    background-color: transparent;
    background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' version='1.1' height='10px' width='15px'%3E%3Ctext x='0' y='10' fill='gray'%3E%E2%96%BE%3C/text%3E%3C/svg%3E");
    background-repeat: no-repeat;
    background-size: 1.5EM 1EM;
    background-position: right center;
    background-clip: border-box;
    -moz-background-clip: border-box;
    -webkit-background-clip: border-box;
}

    .archive .options select.opt::-ms-expand {
        display: none;
    }

Just be careful with proper URL-encoding because of IE. You must use charset=utf8 (not just utf8), don't use double-quotes (") to delimit SVG attribute values, use apostrophes (') instead to simplify your life. URL-encode s (%3E). In case you havee to print any non-ASCII characters you have to obtain their UTF-8 representation (e.g. BabelMap can help you with that) and then provide that representation in URL-encoded form - e.g. for ? (U+25BE BLACK DOWN-POINTING SMALL TRIANGLE) UTF-8 representation is \xE2\x96\xBE which is %E2%96%BE when URL-encoded.

try setting the body style to:

body { position:relative;}

it worked for me

You can also use UUID class from java.util package, which returns random uuid of 32bit characters String.

java.util.UUID.randomUUID().toString()

http://java.sun.com/j2se/1.5.0/docs/api/java/util/UUID.html

One example would be for modeling trees. If you are using a HashMap to represent a tree structure, where the key is the parent and the value is list of children, then the values for the null key would be the root nodes.

Open psql command line and type :

\d+ table_name

I know that there have already been some good answers, but I came across this question with a Google Search and I wish someone would have pointed out this online checking tool...

http://www.tormus.com/tools/div_checker

You just throw in a URL and it will show you the entire map of the page. Very useful for a quick debug like I needed.

You will also get this error if you have a generic declaration for both your class and your method. For example the code shown below gives this compile error.

public class Foo <T> {

    T var;

    public <T> void doSomething(Class <T> cls) throws InstantiationException, IllegalAccessException {
        this.var = cls.newInstance();
    }

}

This code does compile (note T removed from method declaration):

public class Foo <T> {

    T var;

    public void doSomething(Class <T> cls) throws InstantiationException, IllegalAccessException {
        this.var = cls.newInstance();
    }

}

Maybe you have a file/directory named test in the directory. If this directory exists, and has no dependencies that are more recent, then this target is not rebuild.

To force rebuild on these kind of not-file-related targets, you should make them phony as follows:

.PHONY: all test clean

Note that you can declare all of your phony targets there.

A phony target is one that is not really the name of a file; rather it is just a name for a recipe to be executed when you make an explicit request.

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

Call me lazy but coding a Converter seems like a lot of unnecessary work. I'm using Primefaces and, not having used a plain vanilla JSF2 listbox or dropdown menu before, I just assumed (being lazy) that the widget could handle complex objects, i.e. pass the selected object as is to its corresponding getter/setter like so many other widgets do. I was disappointed to find (after hours of head scratching) that this capability does not exist for this widget type without a Converter. In fact if you supply a setter for the complex object rather than for a String, it fails silently (simply doesn't call the setter, no Exception, no JS error), and I spent a ton of time going through BalusC's excellent troubleshooting tool to find the cause, to no avail since none of those suggestions applied. My conclusion: listbox/menu widget needs adapting that other JSF2 widgets do not. This seems misleading and prone to leading the uninformed developer like myself down a rabbit hole.

In the end I resisted coding a Converter and found through trial and error that if you set the widget value to a complex object, e.g.:

<p:selectOneListbox id="adminEvents" value="#{testBean.selectedEvent}">

... when the user selects an item, the widget can call a String setter for that object, e.g. setSelectedThing(String thingString) {...}, and the String passed is a JSON String representing the Thing object. I can parse it to determine which object was selected. This feels a little like a hack, but less of a hack than a Converter.

Rythm a java template engine now released with an new feature called String interpolation mode which allows you do something like:

String result = Rythm.render("@name is inviting you", "Diana");

The above case shows you can pass argument to template by position. Rythm also allows you to pass arguments by name:

Map<String, Object> args = new HashMap<String, Object>();
args.put("title", "Mr.");
args.put("name", "John");
String result = Rythm.render("Hello @title @name", args);

Note Rythm is VERY FAST, about 2 to 3 times faster than String.format and velocity, because it compiles the template into java byte code, the runtime performance is very close to concatentation with StringBuilder.

Links:

• Check the full featured demonstration
• read a brief introduction to Rythm
• download the latest package or
• fork it

I guess you have two approaches. Both of which have advantages.

Sort then Count or Loop through and use a hash table to do the counting for you.

The hashtable is nice because once you are done processing you also have all the distinct elements. If you had millions of items though, the hash table could end up using a lot of memory if the duplication rate is low. The sort, then count approach would have a much more controllable memory footprint.

First, you have to run below codes in Anaconda prompt,

conda create -n py27 python=2.7  #for version 2.7
activate py27

conda create -n py36 python=3.6  #for version 3.6
activate py36

Then, you have to open Anaconda navigator and, The button might say "install" instead of Launch. After the installation, which takes a few moments, It will be ready to launch.

Thank you, @cloudscomputes and @Francisco Camargo.

For setting up virtual hosts on Apache http-servers that are not yet connected via DNS, I like to use:

curl -s --connect-to ::host-name: http://project1.loc/post.json

Where host-name ist the IP address or the DNS name of the machine on which the web-server is running. This also works well for https-Sites.

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"   

No method can be invoked on a object which is assigned a NULL value. It will give a nullPointerException. Hence, s2.length() is giving an exception.

I'm a bit late to the game but I needed to do something like this on SQL 2012, I haven't fully tested it yet but here is what I came up with.

Above someone posted a static list DST dates so I wrote the below query to compare this code's output to that list... so far it looks correct.

;WITH DT AS 
( 
    SELECT MyDate = GETDATE() 
    UNION ALL 
    SELECT MyDate = DATEADD(YEAR,-1,MyDate) FROM DT
    WHERE DATEADD(YEAR,-1,MyDate) > DATEADD(YEAR, -30, GETDATE())
)
SELECT 
    SpringForward = CASE 
        WHEN MyDate > '2007-01-01' 
        THEN CONVERT(DATETIME, CONVERT(VARCHAR,YEAR(MyDate)) + '-MAR-14 02:00') - DATEPART(DW,CONVERT(VARCHAR,YEAR(MyDate)) + '-MAR-14 02:00' ) + 1
        ELSE CONVERT(DATETIME, CONVERT(VARCHAR,YEAR(MyDate)) + '-APR-07 02:00') - DATEPART(DW,CONVERT(VARCHAR,YEAR(MyDate)) + '-APR-07 02:00' ) + 1 END

If you want to get all the elements in the sequence pair wise, use this approach (the pairwise function is from the examples in the itertools module).

from itertools import tee, izip, chain

def pairwise(seq):
    a,b = tee(seq)
    b.next()
    return izip(a,b)

for current_item, next_item in pairwise(y):
    if compare(current_item, next_item):
        # do what you have to do

If you need to compare the last value to some special value, chain that value to the end

for current, next_item in pairwise(chain(y, [None])):

Write a method minimum3 that returns the smallest of three floating-point numbers. Use the Math.min method to implement minimum3. Incorporate the method into an application that reads three values from the user, determines the smallest value and displays the result.

As far as I know, it doesn't matter which one you use. They're equivalent in the eyes of the compiler. Use whichever one you prefer. I normally use class.

jQuery("input.first").click(function(){
   jQuery("input.second").trigger("click");
   return false;
});

Best practice: one form per product is definitely the way to go.

Benefits:

• It will save you the hassle of having to parse the data to figure out which product was clicked
• It will reduce the size of data being posted

In your specific situation

If you only ever intend to have one form element, in this case a submit button, one form for all should work just fine.

My recommendation Do one form per product, and change your markup to something like:

<form method="post" action="">
    <input type="hidden" name="product_id" value="123">
    <button type="submit" name="action" value="add_to_cart">Add to Cart</button>
</form>

This will give you a much cleaner and usable POST. No parsing. And it will allow you to add more parameters in the future (size, color, quantity, etc).

Note: There's no technical benefit to using <button> vs. <input>, but as a programmer I find it cooler to work with action=='add_to_cart' than action=='Add to Cart'. Besides, I hate mixing presentation with logic. If one day you decide that it makes more sense for the button to say "Add" or if you want to use different languages, you could do so freely without having to worry about your back-end code.

If you're looking to get promise in resource call, you should use

Regions.query().$q.then(function(){ .... })

Update : the promise syntax is changed in current versions which reads

Regions.query().$promise.then(function(){ ..... })

Those who have downvoted don't know what it was and who first added this promise to resource object. I used this feature in late 2012 - yes 2012.

<%= f.submit 'name of button here', :class => 'submit_class_name_here' %>

This should do. If you're getting an error, chances are that you're not supplying the name.

Alternatively, you can style the button without a class:

form#form_id_here input[type=submit]

Try that, as well.

Bundle bundle = new Bundle();
bundle.putString("mykey","abc"); 
bundle.putString("mykey2","abc"); // Put anything what you want

Fragment fragment = new Fragment();
fragment2.setArguments(bundle);

getFragmentManager()
  .beginTransaction()
  .replace(R.id.content, fragment2)
  .commit();

Bundle bundle = this.getArguments(); // in your fragment oncreate

if(bundle != null){
  String mykey = bundle.getString("mykey");
  String mykey2 = bundle.getString("mykey2");
  }

For the sake of proper Javascript

HTMLTextAreaElement.prototype.insertAtCaret = function (text) {
  text = text || '';
  if (document.selection) {
    // IE
    this.focus();
    var sel = document.selection.createRange();
    sel.text = text;
  } else if (this.selectionStart || this.selectionStart === 0) {
    // Others
    var startPos = this.selectionStart;
    var endPos = this.selectionEnd;
    this.value = this.value.substring(0, startPos) +
      text +
      this.value.substring(endPos, this.value.length);
    this.selectionStart = startPos + text.length;
    this.selectionEnd = startPos + text.length;
  } else {
    this.value += text;
  }
};
