Three options:

Option1:

public class TheRepresentativeType {
    public ... SomeVariable {get;set;}
    public ... AnotherVariable {get;set;}
}

public IEnumerable<TheRepresentativeType> TheMethod(SomeParameter)
{
   using (MyDC TheDC = new MyDC())
   {
     var TheQueryFromDB = (....
                           select new TheRepresentativeType{ SomeVariable = ....,
                                        AnotherVariable = ....}
                           ).ToList();

     return TheQueryFromDB;
   } 
}

Option 2:

public IEnumerable TheMethod(SomeParameter)
{
   using (MyDC TheDC = new MyDC())
   {
     var TheQueryFromDB = (....
                           select new TheRepresentativeType{ SomeVariable = ....,
                                        AnotherVariable = ....}
                           ).ToList();
     return TheQueryFromDB;
   } 
}

you can iterate it as object

Option 3:

public IEnumerable<dynamic> TheMethod(SomeParameter)
{
   using (MyDC TheDC = new MyDC())
   {
     var TheQueryFromDB = (....
                           select new TheRepresentativeType{ SomeVariable = ....,
                                        AnotherVariable = ....}
                           ).ToList();

     return TheQueryFromDB; //You may need to call .Cast<dynamic>(), but I'm not sure
   } 
}

and you will be able to iterate it as a dynamic object and access their properties directly

This is a fairly standard communication question. One approach would be to use a ResultReceiver in Activity A:

Intent GotoB=new Intent(A.this,B.class);
GotoB.putExtra("finisher", new ResultReceiver(null) {
    @Override
    protected void onReceiveResult(int resultCode, Bundle resultData) {
        A.this.finish();
    }
});
startActivityForResult(GotoB,1);

and then in Activity B you can just finish it on demand like so:

((ResultReceiver)getIntent().getExtra("finisher")).send(1, new Bundle());

Try something like that.

If I google for "Unable to convert MySQL date/time value to System.DateTime" I see numerous references to a problem accessing MySQL from Visual Studio. Is that your context?

One solution suggested is:

This is not a bug but expected behavior. Please check manual under connect options and set "Allow Zero Datetime" to true, as on attached pictures, and the error will go away.

Reference: http://bugs.mysql.com/bug.php?id=26054

input.next();
String s = input.toString();

change it to

String s = input.next();

May be that's what you were trying to do.

Two problems:

1 - You never told Git to start tracking any file

You write that you ran

git init
git commit -m "first commit"

and that, at that stage, you got

nothing added to commit but untracked files present (use "git add" to track).

Git is telling you that you never told it to start tracking any files in the first place, and it has nothing to take a snapshot of. Therefore, Git creates no commit. Before attempting to commit, you should tell Git (for instance):

Hey Git, you see that README.md file idly sitting in my working directory, there? Could you put it under version control for me? I'd like it to go in my first commit/snapshot/revision...

For that you need to stage the files of interest, using

git add README.md

before running

git commit -m "some descriptive message"

2 - You haven't set up the remote repository

You then ran

git remote add origin https://github.com/VijayNew/NewExample.git

After that, your local repository should be able to communicate with the remote repository that resides at the specified URL (https://github.com/VijayNew/NewExample.git)... provided that remote repo actually exists! However, it seems that you never created that remote repo on GitHub in the first place: at the time of writing this answer, if I try to visit the correponding URL, I get

Before attempting to push to that remote repository, you need to make sure that the latter actually exists. So go to GitHub and create the remote repo in question. Then and only then will you be able to successfully push with

git push -u origin master

Another way to do this would be to add before adding lines in your output, the following line :

output.writerow(dict(zip(dr.fieldnames, dr.fieldnames)))

The zip would return a list of doublet containing the same value. This list could be used to initiate a dictionary.

BufferedReader in = new BufferedReader(new FileReader("<Filename>"));

Then, you can use in.readLine(); to read a single line at a time. To read until the end, write a while loop as such:

String line;
while((line = in.readLine()) != null)
{
    System.out.println(line);
}
in.close();

If you have the developer console (JavaScript) in your browser, you can type this code in:

urls = document.querySelectorAll('a'); for (url in urls) console.log(urls[url].href);

Shortened:

n=$$('a');for(u in n)console.log(n[u].href)

SELECT *
FROM
(
SELECT [Period], [Account], [Value]
FROM TableName
) AS source
PIVOT
(
    MAX([Value])
    FOR [Period] IN ([2000], [2001], [2002])
) as pvt

Another way,

SELECT ACCOUNT,
      MAX(CASE WHEN Period = '2000' THEN Value ELSE NULL END) [2000],
      MAX(CASE WHEN Period = '2001' THEN Value ELSE NULL END) [2001],
      MAX(CASE WHEN Period = '2002' THEN Value ELSE NULL END) [2002]
FROM tableName
GROUP BY Account

You can use a tool like the TrIDNet - File Identifier to look for the Magic Number and other telltales, if the file format is in it's database it may tell you what it is for.

However searching the definitions did not turn up anything for the string "FLDB", but it checks more than magic numbers so it is worth a try.

If you are using Linux File is a command that will do a similar task.

The other thing to try is if you have access to the program that generated this file, there may be DLL's or EXE's from the database software that may contain meta information about the dll's creator which could give you a starting point for looking for software that can read the file outside of the program that originally created the .db file.

Using CLR, here's a much simpler alternative that works in all cases, yet 40% faster than the accepted answer:

using System;
using System.Collections;
using System.Data.SqlTypes;
using System.Text.RegularExpressions;
using Microsoft.SqlServer.Server;

public class UDF
{
    [SqlFunction(FillRowMethodName="FillRow")]
    public static IEnumerable RegexSplit(SqlString s, SqlString delimiter)
    {
        return Regex.Split(s.Value, delimiter.Value);
    }

    public static void FillRow(object row, out SqlString str)
    {
        str = new SqlString((string) row);
    }
}

Of course, it is still 8 times slower than PostgreSQL's regexp_split_to_table.

Since Spark 1.5 you can use a number of date processing functions:

• pyspark.sql.functions.year
• pyspark.sql.functions.month
• pyspark.sql.functions.dayofmonth
• pyspark.sql.functions.dayofweek()
• pyspark.sql.functions.dayofyear
• pyspark.sql.functions.weekofyear()

import datetime
from pyspark.sql.functions import year, month, dayofmonth

elevDF = sc.parallelize([
    (datetime.datetime(1984, 1, 1, 0, 0), 1, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 2, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 3, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 4, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 5, 638.55)
]).toDF(["date", "hour", "value"])

elevDF.select(
    year("date").alias('year'), 
    month("date").alias('month'), 
    dayofmonth("date").alias('day')
).show()
# +----+-----+---+
# |year|month|day|
# +----+-----+---+
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# +----+-----+---+

You can use simple map as with any other RDD:

elevDF = sqlContext.createDataFrame(sc.parallelize([
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=1, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=2, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=3, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=4, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=5, value=638.55)]))

(elevDF
 .map(lambda (date, hour, value): (date.year, date.month, date.day))
 .collect())

and the result is:

[(1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1)]

Btw: datetime.datetime stores an hour anyway so keeping it separately seems to be a waste of memory.

Late to the story but I think some details are overlooked?

if you use

if (uemail !== undefined) {
  //some function
}

You are, technically, comparing variable uemail with variable undefined and, as the latter is not instantiated, it will give both type and value of 'undefined' purely by default, hence the comparison returns true. But it overlooks the potential that a variable by the name of undefined may actually exist -however unlikely- and would therefore then not be of type undefined. In that case, the comparison will return false.

To be correct one would have to declare a constant of type undefined for example:

const _undefined: undefined

and then test by:

if (uemail === _undefined) {
  //some function
}

This test will return true as uemail now equals both value & type of _undefined as _undefined is now properly declared to be of type undefined.

Another way would be

if (typeof(uemail) === 'undefined') {
  //some function
}

In which case the boolean return is based on comparing the two strings on either end of the comparison. This is, from a technical point of view, NOT testing for undefined, although it achieves the same result.

You will need Javascript to do this:

HTML

<input id="datefield" type='date' min='1899-01-01' max='2000-13-13'></input>

JS

var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
 if(dd<10){
        dd='0'+dd
    } 
    if(mm<10){
        mm='0'+mm
    } 

today = yyyy+'-'+mm+'-'+dd;
document.getElementById("datefield").setAttribute("max", today);

I am not certain the exact advantages over aggregate.

The most elegant way to fix this: use pipe. Here is example (my blog). So you can then simply use url | safe pipe to bypass the security.

<iframe [src]="url | safe"></iframe>

Refer to the documentation on npm for details: https://www.npmjs.com/package/safe-pipe

I am not really sure about your question (the meaning of "empty table" etc, or how mappedBy and JoinColumn were not working).

I think you were trying to do a bi-directional relationships.

First, you need to decide which side "owns" the relationship. Hibernate is going to setup the relationship base on that side. For example, assume I make the Post side own the relationship (I am simplifying your example, just to keep things in point), the mapping will look like:

(Wish the syntax is correct. I am writing them just by memory. However the idea should be fine)

public class User{
    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    private List<Post> posts;
}


public class Post {
    @ManyToOne(fetch=FetchType.LAZY)
    @JoinColumn(name="user_id")
    private User user;
}

By doing so, the table for Post will have a column user_id which store the relationship. Hibernate is getting the relationship by the user in Post (Instead of posts in User. You will notice the difference if you have Post's user but missing User's posts).

You have mentioned mappedBy and JoinColumn is not working. However, I believe this is in fact the correct way. Please tell if this approach is not working for you, and give us a bit more info on the problem. I believe the problem is due to something else.

Edit:

Just a bit extra information on the use of mappedBy as it is usually confusing at first. In mappedBy, we put the "property name" in the opposite side of the bidirectional relationship, not table column name.

Solution if you are using Ionic Capacitor, Angular Material, and need to support iOS 11.

                document.activeElement.parentElement.parentElement.scrollIntoView({block: 'center', behavior: 'smooth'}); 

The key is to scroll to the parent of the parent which is the wrapper around the input. This wrapper includes the label for the input which is now no longer cut off.

If you only need to support iOS 14 the "block" center param actually works, so this is sufficient:

                document.activeElement.scrollIntoView({block: 'center', behavior: 'smooth'}); 

A combination of good answers:

var count = {};
var arr = ['a', 'b', 'c', 'd', 'd', 'e', 'a', 'b', 'c', 'f', 'g', 'h', 'h', 'h', 'e', 'a'];
var iterator = function (element) {
    count[element] = (count[element] || 0) + 1;
}

if (arr.forEach) {
    arr.forEach(function (element) {
        iterator(element);
    });
} else {
    for (var i = 0; i < arr.length; i++) {
        iterator(arr[i]);
    }
}  

Hope it's helpful.

if you just scrollheight it will make a problem when user will want to see his previous message. so you need to make something that when new message come only then the code. use jquery latest version. 1.here I checked the height before message loaded. 2. again check the new height. 3. if the height is different only that time it will scroll otherwise it will not scroll. 4. not in the if condition you can put any ringtone or any other feature that you need. that will play when new message will come. thanks

var oldscrollHeight = $("#messages").prop("scrollHeight");
$.get('msg_show.php', function(data) {
    div.html(data);
    var newscrollHeight = $("#messages").prop("scrollHeight"); //Scroll height after the request
    if (newscrollHeight > oldscrollHeight) {
        $("#messages").animate({
            scrollTop: newscrollHeight
        }, 'normal'); //Autoscroll to bottom of div
    }

I usually use BOOST_FOREACH:

#include <boost/foreach.hpp>

BOOST_FOREACH( vector_type::value_type& value, v ) {
    // do something with 'value'
}

It works on STL containers, arrays, C-style strings, etc.

This is an old thread, but I have just encountered this situation and discovered a neat way around it. I was trying to run a setup.exe, but the focus was returning to the next line of the script without waiting for the setup.exe to finish. I tried the above solutions with no luck.

In the end, piping the command through more did the trick.

setup.exe {arguments} | more

First, a clarification of terminology: we are assigning a Child object to a variable of type Parent. Parent is a reference to an object that happens to be a subtype of Parent, a Child.

It is only useful in a more complicated example. Imagine you add getEmployeeDetails to the class Parent:

public String getEmployeeDetails() {
    return "Name: " + name;
}

We could override that method in Child to provide more details:

@Override
public String getEmployeeDetails() {
    return "Name: " + name + " Salary: " + salary;
}

Now you can write one line of code that gets whatever details are available, whether the object is a Parent or Child:

parent.getEmployeeDetails();

The following code:

Parent parent = new Parent();
parent.name = 1;
Child child = new Child();
child.name = 2;
child.salary = 2000;
Parent[] employees = new Parent[] { parent, child };
for (Parent employee : employees) {
    employee.getEmployeeDetails();
}

Will result in the output:

Name: 1
Name: 2 Salary: 2000

We used a Child as a Parent. It had specialized behavior unique to the Child class, but when we called getEmployeeDetails() we could ignore the difference and focus on how Parent and Child are similar. This is called subtype polymorphism.

Your updated question asks why Child.salary is not accessible when the Childobject is stored in a Parent reference. The answer is the intersection of "polymorphism" and "static typing". Because Java is statically typed at compile time you get certain guarantees from the compiler but you are forced to follow rules in exchange or the code won't compile. Here, the relevant guarantee is that every instance of a subtype (e.g. Child) can be used as an instance of its supertype (e.g. Parent). For instance, you are guaranteed that when you access employee.getEmployeeDetails or employee.name the method or field is defined on any non-null object that could be assigned to a variable employee of type Parent. To make this guarantee, the compiler considers only that static type (basically, the type of the variable reference, Parent) when deciding what you can access. So you cannot access any members that are defined on the runtime type of the object, Child.

When you truly want to use a Child as a Parent this is an easy restriction to live with and your code will be usable for Parent and all its subtypes. When that is not acceptable, make the type of the reference Child.

The slicing problem in C++ arises from the value semantics of its objects, which remained mostly due to compatibility with C structs. You need to use explicit reference or pointer syntax to achieve "normal" object behavior found in most other languages that do objects, i.e., objects are always passed around by reference.

The short answers is that you slice the object by assigning a derived object to a base object by value, i.e. the remaining object is only a part of the derived object. In order to preserve value semantics, slicing is a reasonable behavior and has its relatively rare uses, which doesn't exist in most other languages. Some people consider it a feature of C++, while many considered it one of the quirks/misfeatures of C++.

You try this.

I have already tried it in my django template.

It will work fine. Just remove the curly braces pair {{ and }} from {{source}}.

I have also added <table> tag and that's it.

After modification your code will look something like below.

{% for source in sources %}
   <table>
      <tr>
          <td>{{ source }}</td>
          <td>
              {% if title == source %}
                Just now! 
              {% endif %}
          </td>
      </tr>
   </table>
{% endfor %}

My dictionary looks like below,

{'title':"Rishikesh", 'sources':["Hemkesh", "Malinikesh", "Rishikesh", "Sandeep", "Darshan", "Veeru", "Shwetabh"]}

and OUTPUT looked like below once my template got rendered.

Hemkesh 
Malinikesh  
Rishikesh   Just now!
Sandeep 
Darshan 
Veeru   
Shwetabh    

You can view loopback traffic live in Wireshark by having it read RawCap's output instantly. cmaynard describes this ingenious approach at the Wireshark forums. I will cite it here:

[...] if you want to view live traffic in Wireshark, you can still do it by running RawCap from one command-line and running Wireshark from another. Assuming you have cygwin's tail available, this could be accomplished using something like so:

cmd1: RawCap.exe -f 127.0.0.1 dumpfile.pcap

cmd2: tail -c +0 -f dumpfile.pcap | Wireshark.exe -k -i -

It requires cygwin's tail, and I could not find a way to do this with Windows' out-of-the-box tools. His approach works very fine for me and allows me to use all of Wiresharks filter capabilities on captured loopback traffic live.

Here is an example from my HOW TO Matlab page:

close all; clear all;

img   = imread('lena.tif','tif');
imagesc(img)
img   = fftshift(img(:,:,2));
F     = fft2(img);

figure;

imagesc(100*log(1+abs(fftshift(F)))); colormap(gray); 
title('magnitude spectrum');

figure;
imagesc(angle(F));  colormap(gray);
title('phase spectrum');

This gives the magnitude spectrum and phase spectrum of the image. I used a color image, but you can easily adjust it to use gray image as well.

ps. I just noticed that on Matlab 2012a the above image is no longer included. So, just replace the first line above with say

img = imread('ngc6543a.jpg');

and it will work. I used an older version of Matlab to make the above example and just copied it here.

On the scaling factor

When we plot the 2D Fourier transform magnitude, we need to scale the pixel values using log transform to expand the range of the dark pixels into the bright region so we can better see the transform. We use a c value in the equation

s = c log(1+r) 

There is no known way to pre detrmine this scale that I know. Just need to try different values to get on you like. I used 100 in the above example.

The problem happened because I was trying to bind a HTML element before it was created.

My script was loaded on top of the HTML and it needs to be loaded at the bottom of my HTML code.

It's entirely possible in browser-side javascript.

The easy way:

The readAsDataURL() method might already encode it as base64 for you. You'll probably need to strip out the beginning stuff (up to the first ,), but that's no biggie. This would take all the fun out though.

The hard way:

If you want to try it the hard way (or it doesn't work), look at readAsArrayBuffer(). This will give you a Uint8Array and you can use the method specified. This is probably only useful if you want to mess with the data itself, such as manipulating image data or doing other voodoo magic before you upload.

There are two methods:

• Convert to string and use the built-in btoa or similar
  • I haven't tested all cases, but works for me- just get the char-codes
• Convert directly from a Uint8Array to base64

I recently implemented tar in the browser. As part of that process, I made my own direct Uint8Array->base64 implementation. I don't think you'll need that, but it's here if you want to take a look; it's pretty neat.

What I do now:

The code for converting to string from a Uint8Array is pretty simple (where buf is a Uint8Array):

function uint8ToString(buf) {
    var i, length, out = '';
    for (i = 0, length = buf.length; i < length; i += 1) {
        out += String.fromCharCode(buf[i]);
    }
    return out;
}

From there, just do:

var base64 = btoa(uint8ToString(yourUint8Array));

Base64 will now be a base64-encoded string, and it should upload just peachy. Try this if you want to double check before pushing:

window.open("data:application/octet-stream;base64," + base64);

This will download it as a file.

Other info:

To get the data as a Uint8Array, look at the MDN docs:

• https://developer.mozilla.org/en/DOM/FileReader

implementation 'com.github.bumptech.glide:glide:4.8.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'


RequestOptions options=new RequestOptions();
        options.centerCrop().placeholder(getResources().getDrawable(R.drawable.user_placeholder));
        Glide.with(this)
                .load(preferenceSingleTon.getImage())
                .apply(options)
                .into(ProfileImage);

It would be nice to have full support for set methods for dictionaries (and not the unholy mess we're getting with Python 3.9) so that you could simply "remove" a set of keys. However, as long as that's not the case, and you have a large dictionary with potentially a large number of keys to remove, you might want to know about the performance. So, I've created some code that creates something large enough for meaningful comparisons: a 100,000 x 1000 matrix, so 10,000,00 items in total.

from itertools import product
from time import perf_counter

# make a complete worksheet 100000 * 1000
start = perf_counter()
prod = product(range(1, 100000), range(1, 1000))
cells = {(x,y):x for x,y in prod}
print(len(cells))

print(f"Create time {perf_counter()-start:.2f}s")
clock = perf_counter()
# remove everything above row 50,000

keys = product(range(50000, 100000), range(1, 100))

# for x,y in keys:
#     del cells[x, y]

for n in map(cells.pop, keys):
    pass

print(len(cells))
stop = perf_counter()
print(f"Removal time {stop-clock:.2f}s")

10 million items or more is not unusual in some settings. Comparing the two methods on my local machine I see a slight improvement when using map and pop, presumably because of fewer function calls, but both take around 2.5s on my machine. But this pales in comparison to the time required to create the dictionary in the first place (55s), or including checks within the loop. If this is likely then its best to create a set that is a intersection of the dictionary keys and your filter:

keys = cells.keys() & keys

In summary: del is already heavily optimised, so don't worry about using it.

In the old days, "/opt" was used by UNIX vendors like AT&T, Sun, DEC and 3rd-party vendors to hold "Option" packages; i.e. packages that you might have paid extra money for. I don't recall seeing "/opt" on Berkeley BSD UNIX. They used "/usr/local" for stuff that you installed yourself.

But of course, the true "meaning" of the different directories has always been somewhat vague. That is arguably a good thing, because if these directories had precise (and rigidly enforced) meanings you'd end up with a proliferation of different directory names.

According to the Filesystem Hierarchy Standard, /opt is for "the installation of add-on application software packages". /usr/local is "for use by the system administrator when installing software locally".

Restarting the SQL Server will clear up the log space used by your database. If this however is not an option, you can try the following:

* Issue a CHECKPOINT command to free up log space in the log file.

* Check the available log space with DBCC SQLPERF('logspace'). If only a small 
  percentage of your log file is actually been used, you can try a DBCC SHRINKFILE 
  command. This can however possibly introduce corruption in your database. 

* If you have another drive with space available you can try to add a file there in 
  order to get enough space to attempt to resolve the issue.

Hope this will help you in finding your solution.

For an array of strings (but not an array of objects), you can check if an item exists by calling .indexOf() and if it doesn't then just push the item into the array:

var newItem = "NEW_ITEM_TO_ARRAY";_x000D_
var array = ["OLD_ITEM_1", "OLD_ITEM_2"];_x000D_
_x000D_
array.indexOf(newItem) === -1 ? array.push(newItem) : console.log("This item already exists");_x000D_
_x000D_
console.log(array)

Use the exec() method. For example, say you have a dictionary and you want to turn each key into a variable with its original dictionary value can do the following.

Python 2

>>> c = {"one": 1, "two": 2}
>>> for k,v in c.iteritems():
...    exec("%s=%s" % (k,v))

>>> one
1
>>> two
2

Python 3

>>> c = {"one": 1, "two": 2}
>>> for k,v in c.items():
...    exec("%s=%s" % (k,v))

>>> one
1
>>> two
2

Beware if your page is including other .jsp or .jspf (fragment)! If you don't set

<%@ page session="false" %>

on them as well, the parent page will end up starting a new session and setting the JSESSIONID cookie.

For .jspf pages in particular, this happens if you configured your web.xml with such a snippet:

<jsp-config>
    <jsp-property-group>
        <url-pattern>*.jspf</url-pattern>
    </jsp-property-group>
</jsp-config>

in order to enable scriptlets inside them.

use further as

rs.getString(1);
rs.getInt(2);

1, 2 is the column number of table and set int or string as per data-type of coloumn

there are specific builds of command line tools for different major OSX versions available from the Downloads for Apple Developers site. Be sure to get the latest release of the version for your OS.

I have solved it by doing 3 things:

1. Added this repository to my POM:

   <repository>
       <id>spring-milestone</id>
       <name>Spring Maven MILESTONE Repository</name>
       <url>http://repo.springsource.org/libs-milestone</url>
   </repository>
   

2. I'm using this version of spring-jpa:

   <dependency>
       <groupId>org.springframework.data</groupId>
       <artifactId>spring-data-jpa</artifactId>
       <version>1.2.0.RELEASE</version>
   </dependency>
   

3. I removed the xsd versions from my context (although I'm not sure it is necessary):

   <?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:context="http://www.springframework.org/schema/context"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
     xmlns:jpa="http://www.springframework.org/schema/data/jpa" xmlns:tx="http://www.springframework.org/schema/tx"
     xsi:schemaLocation="
      http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
      http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
      http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd

I hope this helps.

Just download and install "Samsung Kies" from this link. and everything would work as required.

Before installing, uninstall the drivers you have installed for your device.

Update:

Two possible solutions:

1. Try with the Google USB driver which comes with the SDK.
2. Download and install the Samsung USB driver from this link as suggested by Mauricio Gracia Gutierrez

I had issues getting the above code to work within cookie.js. The following code managed to create the correct timestamp for the cookie expiration in my instance.

var inFifteenMinutes = new Date(new Date().getTime() + 15 * 60 * 1000);

This was from the FAQs for Cookie.js

breast$class <- as.numeric(as.character(breast$class))

If you have many columns to convert to numeric

indx <- sapply(breast, is.factor)
breast[indx] <- lapply(breast[indx], function(x) as.numeric(as.character(x)))

Another option is to use stringsAsFactors=FALSE while reading the file using read.table or read.csv

Just in case, other options to create/change columns

 breast[,'class'] <- as.numeric(as.character(breast[,'class']))

or

 breast <- transform(breast, class=as.numeric(as.character(breast)))

ListName.sort() will sort it alphabetically. You can add reverse=False/True in the brackets to reverse the order of items: ListName.sort(reverse=False)

getting following error

It happens:  Error: 
      ngModel cannot be used to register form controls with a parent formGroup directive.  Try using
      formGroup's partner directive "formControlName" instead.  Example:

Try removing the float attribute from span6:

{ float:none !important; }

I had the same problem. My solution was to make all vectors numeric.

Here's another example. I'm creating a QRCode as a PNG via a ByteArrayOutputStream. The resource returns a Response object, and the stream's data is the entity.

To illustrate the response code handling, I've added handling of cache headers (If-modified-since, If-none-matches, etc).

@Path("{externalId}.png")
@GET
@Produces({"image/png"})
public Response getAsImage(@PathParam("externalId") String externalId, 
        @Context Request request) throws WebApplicationException {

    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    // do something with externalId, maybe retrieve an object from the
    // db, then calculate data, size, expirationTimestamp, etc

    try {
        // create a QRCode as PNG from data     
        BitMatrix bitMatrix = new QRCodeWriter().encode(
                data, 
                BarcodeFormat.QR_CODE, 
                size, 
                size
        );
        MatrixToImageWriter.writeToStream(bitMatrix, "png", stream);

    } catch (Exception e) {
        // ExceptionMapper will return HTTP 500 
        throw new WebApplicationException("Something went wrong …")
    }

    CacheControl cc = new CacheControl();
    cc.setNoTransform(true);
    cc.setMustRevalidate(false);
    cc.setNoCache(false);
    cc.setMaxAge(3600);

    EntityTag etag = new EntityTag(HelperBean.md5(data));

    Response.ResponseBuilder responseBuilder = request.evaluatePreconditions(
            updateTimestamp,
            etag
    );
    if (responseBuilder != null) {
        // Preconditions are not met, returning HTTP 304 'not-modified'
        return responseBuilder
                .cacheControl(cc)
                .build();
    }

    Response response = Response
            .ok()
            .cacheControl(cc)
            .tag(etag)
            .lastModified(updateTimestamp)
            .expires(expirationTimestamp)
            .type("image/png")
            .entity(stream.toByteArray())
            .build();
    return response;
}   

Please don't beat me up in case stream.toByteArray() is a no-no memory wise :) It works for my <1KB PNG files...

The accepted answer is very old.

I found a better modern answer here:

https://kevinmccarthy.org/2016/07/25/streaming-subprocess-stdin-and-stdout-with-asyncio-in-python/

and made some changes:

1. make it work on windows
2. make it work with multiple commands

import sys
import asyncio

if sys.platform == "win32":
    asyncio.set_event_loop_policy(asyncio.WindowsProactorEventLoopPolicy())


async def _read_stream(stream, cb):
    while True:
        line = await stream.readline()
        if line:
            cb(line)
        else:
            break


async def _stream_subprocess(cmd, stdout_cb, stderr_cb):
    try:
        process = await asyncio.create_subprocess_exec(
            *cmd, stdout=asyncio.subprocess.PIPE, stderr=asyncio.subprocess.PIPE
        )

        await asyncio.wait(
            [
                _read_stream(process.stdout, stdout_cb),
                _read_stream(process.stderr, stderr_cb),
            ]
        )
        rc = await process.wait()
        return process.pid, rc
    except OSError as e:
        # the program will hang if we let any exception propagate
        return e


def execute(*aws):
    """ run the given coroutines in an asyncio loop
    returns a list containing the values returned from each coroutine.
    """
    loop = asyncio.get_event_loop()
    rc = loop.run_until_complete(asyncio.gather(*aws))
    loop.close()
    return rc


def printer(label):
    def pr(*args, **kw):
        print(label, *args, **kw)

    return pr


def name_it(start=0, template="s{}"):
    """a simple generator for task names
    """
    while True:
        yield template.format(start)
        start += 1


def runners(cmds):
    """
    cmds is a list of commands to excecute as subprocesses
    each item is a list appropriate for use by subprocess.call
    """
    next_name = name_it().__next__
    for cmd in cmds:
        name = next_name()
        out = printer(f"{name}.stdout")
        err = printer(f"{name}.stderr")
        yield _stream_subprocess(cmd, out, err)


if __name__ == "__main__":
    cmds = (
        [
            "sh",
            "-c",
            """echo "$SHELL"-stdout && sleep 1 && echo stderr 1>&2 && sleep 1 && echo done""",
        ],
        [
            "bash",
            "-c",
            "echo 'hello, Dave.' && sleep 1 && echo dave_err 1>&2 && sleep 1 && echo done",
        ],
        [sys.executable, "-c", 'print("hello from python");import sys;sys.exit(2)'],
    )

    print(execute(*runners(cmds)))

It is unlikely that the example commands will work perfectly on your system, and it doesn't handle weird errors, but this code does demonstrate one way to run multiple subprocesses using asyncio and stream the output.

Add below code to your web.config file then run the project...

    <runtime>

In my own case I have the following error

Illegal mix of collations (utf8_general_ci,IMPLICIT) and (utf8_unicode_ci,IMPLICIT) for operation '='

$this->db->select("users.username as matric_no, CONCAT(users.surname, ' ', users.first_name, ' ', users.last_name) as fullname") ->join('users', 'users.username=classroom_students.matric_no', 'left') ->where('classroom_students.session_id', $session) ->where('classroom_students.level_id', $level) ->where('classroom_students.dept_id', $dept);

After weeks of google searching I noticed that the two fields I am comparing consists of different collation name. The first one i.e username is of utf8_general_ci while the second one is of utf8_unicode_ci so I went back to the structure of the second table and changed the second field (matric_no) to utf8_general_ci and it worked like a charm.

I had written this program in java. I think this might also help:

public class Anagram {
    public static void main(String[] args) {
        checkAnagram("listen", "silent");
    }

    public static void checkAnagram(String str1, String str2) {
        boolean isAnagram = false;
        str1 = sortStr(str1);
        str2 = sortStr(str2);
        if (str1.equals(str2)) {
            isAnagram = true;
        }
        if (isAnagram) {
            System.out.println("Two strings are anagram");
        } else {
            System.out.println("Two string are not anagram");
        }

    }

    public static String sortStr(String str) {
        char[] strArr = str.toCharArray();
        for (int i = 0; i < str.length(); i++) {
            for (int j = i + 1; j < str.length(); j++) {
                if (strArr[i] > strArr[j]) {
                    char temp = strArr[i];
                    strArr[i] = strArr[j];
                    strArr[j] = temp;
                }
            }
        }
        String output = String.valueOf(strArr);
        return output;
    }
}

If you are on MacOS X and having problems with Imagemagick's convert, you might try reinstalling it with RSVG lib. Using HomeBrew:

brew remove imagemagick
brew install imagemagick --with-librsvg

Verify that it's delegating correctly:

$ convert -version
Version: ImageMagick 6.8.9-8 Q16 x86_64 2014-12-17 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2014 ImageMagick Studio LLC
Features: DPC Modules
Delegates: bzlib cairo fontconfig freetype jng jpeg lcms ltdl lzma png rsvg tiff xml zlib

It should display rsvg.

Right now you're setting the innerHTML to an entire div element; you want to set it to just the innerHTML. Also, I think you want MyDiv2.innerHTML = MyDiv 1 .innerHTML. Also, I think the argument to document.getElementById is case sensitive. You were passing Div2 when you wanted DIV2

var MyDiv1 = Document.getElementById('DIV1');
var MyDiv2 = Document.getElementById('DIV2');
MyDiv2.innerHTML = MyDiv1.innerHTML; 

Also, this code will run before your DOM is ready. You can either put this script at the bottom of your body like paislee said, or put it in your body's onload function

<body onload="loadFunction()">

and then

function loadFunction(){
    var MyDiv1 = Document.getElementById('DIV1');
    var MyDiv2 = Document.getElementById('DIV2');
    MyDiv2.innerHTML = MyDiv1.innerHTML; 
}

Simply install Microsot.ReportViewer.2012.Runtime nuget package as shown in this answer https://stackoverflow.com/a/33014040/2198830

There's an experimental CSS property called text-stroke, supported on some browsers behind a -webkit prefix.

h1 {_x000D_
    -webkit-text-stroke: 2px black; /* width and color */_x000D_
_x000D_
    font-family: sans; color: yellow;_x000D_
}

<h1>Hello World</h1>

Another possible trick would be to use four shadows, one pixel each on all directions, using property text-shadow:

h1 {_x000D_
    /* 1 pixel black shadow to left, top, right and bottom */_x000D_
    text-shadow: -1px 0 black, 0 1px black, 1px 0 black, 0 -1px black;_x000D_
_x000D_
    font-family: sans; color: yellow;_x000D_
}

<h1>Hello World</h1>

But it would get blurred for more than 1 pixel thickness.

You can change the default with an alter table set default charset but that won't change the charset of the existing columns. To change that you need to use a alter table modify column.

Changing the charset of a column only means that it will be able to store a wider range of characters. Your application talks to the db using the mysql client so you may need to change the client encoding as well.

Got this from YouTube page which has a really simple set up. Absolutely maintainable and reusable.

.circle {_x000D_
    position: absolute;_x000D_
    top: 4px;_x000D_
    color: white;_x000D_
    background-color: red;_x000D_
    width: 18px;_x000D_
    height: 18px;_x000D_
    border-radius: 50%;_x000D_
    line-height: 18px;_x000D_
    font-size: 10px;_x000D_
    text-align: center;_x000D_
    cursor: pointer;_x000D_
    z-index: 999;_x000D_
}

<div class="circle">2</div>

You can also try installing it in Visual Studio via Package Manager.

Run Install-Package Microsoft.Office.Interop.Excel in the Package Console. This will automatically add it as a project reference.

Use is like this:

Using Excel=Microsoft.Office.Interop.Excel;

when your document is ready that doesn't mean that your iframe is ready too,
so you should listen to the iframe load event then access your contents:

$(function() {
    $("#my-iframe").bind("load",function(){
        $(this).contents().find("[tokenid=" + token + "]").html();
    });
});

In C#, the For loop is slightly faster.

For loop average about 2.95 to 3.02 ms.

The While loop averaged about 3.05 to 3.37 ms.

Quick little console app to prove:

 class Program
    {
        static void Main(string[] args)
        {
            int max = 1000000000;
            Stopwatch stopWatch = new Stopwatch();

            if (args.Length == 1 && args[0].ToString() == "While")
            {
                Console.WriteLine("While Loop: ");
                stopWatch.Start();
                WhileLoop(max);
                stopWatch.Stop();
                DisplayElapsedTime(stopWatch.Elapsed);
            }
            else
            {
                Console.WriteLine("For Loop: ");
                stopWatch.Start();
                ForLoop(max);
                stopWatch.Stop();
                DisplayElapsedTime(stopWatch.Elapsed);
            }
        }

        private static void WhileLoop(int max)
        {
            int i = 0;
            while (i <= max)
            {
                //Console.WriteLine(i);
                i++;
            };
        }

        private static void ForLoop(int max)
        {
            for (int i = 0; i <= max; i++)
            {
                //Console.WriteLine(i);
            }
        }

        private static void DisplayElapsedTime(TimeSpan ts)
        {
            // Format and display the TimeSpan value.
            string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}",
                ts.Hours, ts.Minutes, ts.Seconds,
                ts.Milliseconds / 10);
            Console.WriteLine(elapsedTime, "RunTime");
        }
    }

If the value returned is null, use:

if(value.isEmpty());

Sometime to check null, if(value == null) in java, it might not give true even the String is null.

Use the Oracle documentation and search for keyword "trigger" in your browser.

This approach should work with other metadata type questions.

When working with Windows Azure Web role or any other host that runs your app in Limited Trust do not forget that you will not be allowed to access registry or unmanaged code. Hybrid approach - combination of try-catch-for-registry and in-memory dictionary looks like a good solution that has a bit of everything.

pandas.DataFrame.query
query was made for exactly this purpose. Consider the dataframe df

import pandas as pd
import numpy as np

np.random.seed([3,1415])
df = pd.DataFrame(
    np.random.randint(10, size=(10, 5)),
    columns=list('ABCDE')
)

df

   A  B  C  D  E
0  0  2  7  3  8
1  7  0  6  8  6
2  0  2  0  4  9
3  7  3  2  4  3
4  3  6  7  7  4
5  5  3  7  5  9
6  8  7  6  4  7
7  6  2  6  6  5
8  2  8  7  5  8
9  4  7  6  1  5

Let's use query to filter all rows where D > B

df.query('D > B')

   A  B  C  D  E
0  0  2  7  3  8
1  7  0  6  8  6
2  0  2  0  4  9
3  7  3  2  4  3
4  3  6  7  7  4
5  5  3  7  5  9
7  6  2  6  6  5

Which we chain

df.query('D > B').query('C > B')
# equivalent to
# df.query('D > B and C > B')
# but defeats the purpose of demonstrating chaining

   A  B  C  D  E
0  0  2  7  3  8
1  7  0  6  8  6
4  3  6  7  7  4
5  5  3  7  5  9
7  6  2  6  6  5

Cross Join: http://www.dba-oracle.com/t_garmany_9_sql_cross_join.htm

TLDR; Generates a all possible combinations between 2 tables (Carthesian product)

(Full) Outer Join: http://www.w3schools.com/Sql/sql_join_full.asp

TLDR; Returns every row in both tables and also results that have the same values (matches in CONDITION)

If only the column names are available like :

cnms <- c("Nam1","Nam2","Nam3")

To create an empty data frame with the above variable names, first create a data.frame object:

emptydf <- data.frame()

Now call zeroth element of every column, thus creating an empty data frame with the given variable names:

for( i in 1:length(cnms)){
     emptydf[0,eval(cnms[i])]
 }

I had a similar error..This might be due to two reasons. a) If you have used variables, re-evaluate the expressions in which variables are used and make sure the expression is evaluated without errors. b) If you are deleting the excel sheet and creating excel sheet on the fly in your package.

From http://matplotlib.sourceforge.net/examples/event_handling/pick_event_demo.html :

from matplotlib.pyplot import figure, show
import numpy as npy
from numpy.random import rand


if 1: # picking on a scatter plot (matplotlib.collections.RegularPolyCollection)

    x, y, c, s = rand(4, 100)
    def onpick3(event):
        ind = event.ind
        print('onpick3 scatter:', ind, npy.take(x, ind), npy.take(y, ind))

    fig = figure()
    ax1 = fig.add_subplot(111)
    col = ax1.scatter(x, y, 100*s, c, picker=True)
    #fig.savefig('pscoll.eps')
    fig.canvas.mpl_connect('pick_event', onpick3)

show()

I'm working on Crud for my app. This is how I did it Got Reactstrap as my dependency.

import React, { useState, setState } from 'react';
import 'bootstrap/dist/css/bootstrap.min.css';
import firebase from 'firebase';
// import { LifeCrud } from '../CRUD/Crud';
import { Row, Card, Col, Button } from 'reactstrap';
import InsuranceActionInput from '../CRUD/InsuranceActionInput';

const LifeActionCreate = () => {
  let [newLifeActionLabel, setNewLifeActionLabel] = React.useState();

  const onCreate = e => {
    const db = firebase.firestore();

    db.collection('actions').add({
      label: newLifeActionLabel
    });
    alert('New Life Insurance Added');
    setNewLifeActionLabel('');
  };

  return (
    <Card style={{ padding: '15px' }}>
      <form onSubmit={onCreate}>
        <label>Name</label>
        <input
          value={newLifeActionLabel}
          onChange={e => {
            setNewLifeActionLabel(e.target.value);
          }}
          placeholder={'Name'}
        />

        <Button onClick={onCreate}>Create</Button>
      </form>
    </Card>
  );
};

Some React Hooks in there

You could do Char(13) and Char(10). Cr and Lf.

Char() works in SQL Server, I don't know about other databases.

It worked for me:

.vcontainer {
    min-height: 10em;
    display: table-cell;
    vertical-align: middle;
}

Here is a very simplified explanation:

1. Your web browser downloads the web server's certificate, which contains the public key of the web server. This certificate is signed with the private key of a trusted certificate authority.

2. Your web browser comes installed with the public keys of all of the major certificate authorities. It uses this public key to verify that the web server's certificate was indeed signed by the trusted certificate authority.

3. The certificate contains the domain name and/or ip address of the web server. Your web browser confirms with the certificate authority that the address listed in the certificate is the one to which it has an open connection.

4. Your web browser generates a shared symmetric key which will be used to encrypt the HTTP traffic on this connection; this is much more efficient than using public/private key encryption for everything. Your browser encrypts the symmetric key with the public key of the web server then sends it back, thus ensuring that only the web server can decrypt it, since only the web server has its private key.

Note that the certificate authority (CA) is essential to preventing man-in-the-middle attacks. However, even an unsigned certificate will prevent someone from passively listening in on your encrypted traffic, since they have no way to gain access to your shared symmetric key.

Quick and dirty fix

class MyData:
    def __init__(string=None,list=None):
        if string is not None:
            #do stuff
        elif list is not None:
            #do other stuff
        else:
            #make data empty

Then you can call it with

MyData(astring)
MyData(None, alist)
MyData()

Refresh gradle project on Eclipse solved this problem for me

I am using following code to decode base64 string in node API nodejs version 10.7.0

let data = 'c3RhY2thYnVzZS5jb20=';  // Base64 string
let buff = new Buffer(data, 'base64');  //Buffer
let text = buff.toString('ascii');  //this is the data type that you want your Base64 data to convert to
console.log('"' + data + '" converted from Base64 to ASCII is "' + text + '"'); 

Please don't try to run above code in console of the browser, won't work. Put the code in server side files of nodejs. I am using above line code in API development.

Use this method to check the network state:

private void checkInternetConnection() {

    if (br == null) {

        br = new BroadcastReceiver() {

            @Override
            public void onReceive(Context context, Intent intent) {

                Bundle extras = intent.getExtras();

But what if the container is not the viewport (body)?

This question is asked in a comment by Alex under the accepted answer.

That fact does not mean vw cannot be used to some extent to size for that container. Now to see any variation at all one has to be assuming that the container in some way is flexible in size. Whether through a direct percentage width or through being 100% minus margins. The point becomes "moot" if the container is always set to, let's say, 200px wide--then just set a font-size that works for that width.

Example 1

With a flexible width container, however, it must be realized that in some way the container is still being sized off the viewport. As such, it is a matter of adjusting a vw setting based off that percentage size difference to the viewport, which means taking into account the sizing of parent wrappers. Take this example:

div {
    width: 50%;
    border: 1px solid black;
    margin: 20px;
    font-size: 16px;
    /* 100 = viewport width, as 1vw = 1/100th of that
       So if the container is 50% of viewport (as here)
       then factor that into how you want it to size.
       Let's say you like 5vw if it were the whole width,
       then for this container, size it at 2.5vw (5 * .5 [i.e. 50%])
    */
    font-size: 2.5vw;
}

Assuming here the div is a child of the body, it is 50% of that 100% width, which is the viewport size in this basic case. Basically, you want to set a vw that is going to look good to you. As you can see in my comment in the above CSS content, you can "think" through that mathematically with respect to the full viewport size, but you don't need to do that. The text is going to "flex" with the container because the container is flexing with the viewport resizing. UPDATE: here's an example of two differently sized containers.

Example 2

You can help ensure viewport sizing by forcing the calculation based off that. Consider this example:

html {width: 100%;} /* Force 'html' to be viewport width */
body {width: 150%; } /* Overflow the body */

div {
    width: 50%;
    border: 1px solid black;
    margin: 20px;
    font-size: 16px;
    /* 100 = viewport width, as 1vw = 1/100th of that
       Here, the body is 150% of viewport, but the container is 50%
       of viewport, so both parents factor  into how you want it to size.
       Let's say you like 5vw if it were the whole width,
       then for this container, size it at 3.75vw
       (5 * 1.5 [i.e. 150%]) * .5 [i.e. 50%]
    */
    font-size: 3.75vw;
}

The sizing is still based off viewport, but is in essence set up based off the container size itself.

Should Size of the Container Change Dynamically...

If the sizing of the container element ended up changing dynamically its percentage relationship either via @media breakpoints or via JavaScript, then whatever the base "target" was would need recalculation to maintain the same "relationship" for text sizing.

Take example #1 above. If the div was switched to 25% width by either @media or JavaScript, then at the same time, the font-size would need to adjust in either the media query or by JavaScript to the new calculation of 5vw * .25 = 1.25. This would put the text size at the same size it would have been had the "width" of the original 50% container been reduced by half from viewport sizing, but has now been reduced due to a change in its own percentage calculation.

A Challenge

With the CSS3 calc() function in use, it would become difficult to adjust dynamically, as that function does not work for font-size purposes at this time. So you could not do a pure CSS 3 adjustment if your width is changing on calc(). Of course, a minor adjustment of width for margins may not be enough to warrant any change in font-size, so it may not matter.

check your Bundle identifier for your project and you give Bundle identifier for your app which create on developer.facebook.com that they are same or not.

Supose you have the following scenario:

* 1bd2200 (HEAD, master) another commit
* d258546 bad commit
* 0f1efa9 3rd commit
* bd8aa13 2nd commit
* 34c4f95 1st commit

Where you want to remove d258546 i.e. "bad commit".

You shall try an interactive rebase to remove it: git rebase -i 34c4f95

then your default editor will pop with something like this:

 pick bd8aa13 2nd commit
 pick 0f1efa9 3rd commit
 pick d258546 bad commit
 pick 1bd2200 another commit

 # Rebase 34c4f95..1bd2200 onto 34c4f95
 #
 # Commands:
 #  p, pick = use commit
 #  r, reword = use commit, but edit the commit message
 #  e, edit = use commit, but stop for amending
 #  s, squash = use commit, but meld into previous commit
 #  f, fixup = like "squash", but discard this commit's log message
 #  x, exec = run command (the rest of the line) using shell
 #
 # These lines can be re-ordered; they are executed from top to bottom.
 #
 # If you remove a line here THAT COMMIT WILL BE LOST.
 #
 # However, if you remove everything, the rebase will be aborted.
 #
 # Note that empty commits are commented out

just remove the line with the commit you want to strip and save+exit the editor:

 pick bd8aa13 2nd commit
 pick 0f1efa9 3rd commit
 pick 1bd2200 another commit
 ...

git will proceed to remove this commit from your history leaving something like this (mind the hash change in the commits descendant from the removed commit):

 * 34fa994 (HEAD, master) another commit
 * 0f1efa9 3rd commit
 * bd8aa13 2nd commit
 * 34c4f95 1st commit

Now, since I suppose that you already pushed the bad commit to gitlab, you'll need to repush your graph to the repository (but with the -f option to prevent it from being rejected due to a non fastforwardeable history i.e. git push -f <your remote> <your branch>)

Please be extra careful and make sure that none coworker is already using the history containing the "bad commit" in their branches.

Alternative option:

Instead of rewrite the history, you may simply create a new commit which negates the changes introduced by your bad commit, to do this just type git revert <your bad commit hash>. This option is maybe not as clean, but is far more safe (in case you are not fully aware of what are you doing with an interactive rebase).

You can use this:

NumberFormat formatter = new DecimalFormat("00");  
String s = formatter.format(1); // ----> 01

you can do something like this:

1. Put your local libraries (with extension: .jar, .aar, ...) into 'libs' Folder (or another if you want).

2. In build.gradle (app level), add this line into dependences

   implementation fileTree(include: ['*.jar', '*.aar'], dir: 'libs')

You're missing a FROM and you need to give the subquery an alias.

SELECT COUNT(*) FROM 
(
  SELECT DISTINCT a.my_id, a.last_name, a.first_name, b.temp_val
   FROM dbo.Table_A AS a 
   INNER JOIN dbo.Table_B AS b 
   ON a.a_id = b.a_id
) AS subquery;

If you're using the standard SVN installation the svn:// connection will work on tcpip port 3690 and so it's basically impossible to connect unless you change your network configuration (you said only Http traffic is allowed) or you install the http module and Apache on the server hosting your SVN server.

I tried most of the answers without success. What worked for me was (after following https://stackoverflow.com/a/21279068/2408893):

• right click on project -> Properties
• select Java Build Path
• select the JRE System Library
• click edit
• In execution environment select a jdk

• click Finish
• build and run

My complete code as below is working well:

package ripon.java.mail;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;

public class SendEmail
{
public static void main(String [] args)
{    
    // Sender's email ID needs to be mentioned
     String from = "[email protected]";
     String pass ="test123";
    // Recipient's email ID needs to be mentioned.
   String to = "[email protected]";

   String host = "smtp.gmail.com";

   // Get system properties
   Properties properties = System.getProperties();
   // Setup mail server
   properties.put("mail.smtp.starttls.enable", "true");
   properties.put("mail.smtp.host", host);
   properties.put("mail.smtp.user", from);
   properties.put("mail.smtp.password", pass);
   properties.put("mail.smtp.port", "587");
   properties.put("mail.smtp.auth", "true");

   // Get the default Session object.
   Session session = Session.getDefaultInstance(properties);

   try{
      // Create a default MimeMessage object.
      MimeMessage message = new MimeMessage(session);

      // Set From: header field of the header.
      message.setFrom(new InternetAddress(from));

      // Set To: header field of the header.
      message.addRecipient(Message.RecipientType.TO,
                               new InternetAddress(to));

      // Set Subject: header field
      message.setSubject("This is the Subject Line!");

      // Now set the actual message
      message.setText("This is actual message");

      // Send message
      Transport transport = session.getTransport("smtp");
      transport.connect(host, from, pass);
      transport.sendMessage(message, message.getAllRecipients());
      transport.close();
      System.out.println("Sent message successfully....");
   }catch (MessagingException mex) {
      mex.printStackTrace();
   }
}
}

I used an extension to UIViewController and a struct to make sure that my current view is presented from the favourites

1.Struct for a global Bool

struct PresentedFromFavourites {
static var comingFromFav = false}

2.UIVeiwController extension: presented modally as in the second option by "stefandouganhyde - Option 2 " and solving the back

extension UIViewController {
func returnToFavourites()
{
    // you return to the storyboard wanted by changing the name
    let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
    let mainNavigationController = storyBoard.instantiateViewController(withIdentifier: "HomeNav") as! UINavigationController
    // Set animated to false
    let favViewController = storyBoard.instantiateViewController(withIdentifier: "Favourites")
    self.present(mainNavigationController, animated: false, completion: {
        mainNavigationController.pushViewController(favViewController, animated: false)
    })

}
// call this function in viewDidLoad()
// 
func addBackToFavouritesButton()
{
    if PresentedFromFavourites.comingFromFav
    {
        //Create a button
        // I found this good for most size classes
        let buttonHeight = (self.navigationController?.navigationBar.frame.size.height)! - 15
        let rect = CGRect(x: 2, y: 8, width: buttonHeight, height: buttonHeight)
        let aButton = UIButton(frame: rect)
        // Down a back arrow image from icon8 for free and add it to your image assets  
        aButton.setImage(#imageLiteral(resourceName: "backArrow"), for: .normal)
        aButton.backgroundColor = UIColor.clear
        aButton.addTarget(self, action:#selector(self.returnToFavourites), for: .touchUpInside)
        self.navigationController?.navigationBar.addSubview(aButton)
        PresentedFromFavourites.comingFromFav = false
    }

}}

A couple problems, you aren't delaying by much (.sleep is milliseconds, not seconds), and you're attempting to print in your catch statement. Your code should look more like:

if (i==1) {
    try {
        System.out.println("Scanning...");
        Thread.sleep(1000); // 1 second
    } catch (InterruptedException ex) {
        // handle error
    }
}

The JVM is caching Integer values. Hence the comparison with == only works for numbers between -128 and 127.

Refer: #Immutable_Objects_.2F_Wrapper_Class_Caching

You can use Line height a big as height of the div. But for me best solution is this --> position:relative; top:50%; transform:translate(0,50%);

If your main element has some child elements or text, you could make use of it.

Position your main element relative (or absolute/fixed) and use both :before and :after positioned absolute (in my situation it had to be absolute, don't know about your's).

Now if you want one more pseudo-element, attach an absolute :before to one of the main element's children (if you have only text, put it in a span, now you have an element), which is not relative/absolute/fixed.

This element will start acting like his owner is your main element.

HTML

<div class="circle">
    <span>Some text</span>
</div>

CSS

.circle {
    position: relative; /* or absolute/fixed */
}

.circle:before {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

.circle:after {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

.circle span {
    /* not relative/absolute/fixed */
}

.circle span:before {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

Looking at my system's menu.vim (look for 'Color Scheme submenu') and @chappar's answer, I came up with the following function:

" Returns the list of available color schemes
function! GetColorSchemes()
   return uniq(sort(map(
   \  globpath(&runtimepath, "colors/*.vim", 0, 1),  
   \  'fnamemodify(v:val, ":t:r")'
   \)))
endfunction

It does the following:

1. Gets the list of available color scheme scripts under all runtime paths (globpath, runtimepath)
2. Maps the script paths to their base names (strips parent dirs and extension) (map, fnamemodify)
3. Sorts and removes duplicates (uniq, sort)

Then to use the function I do something like this:

let s:schemes = GetColorSchemes()
if index(s:schemes, 'solarized') >= 0
   colorscheme solarized
elseif index(s:schemes, 'darkblue') >= 0
   colorscheme darkblue
endif

Which means I prefer the 'solarized' and then the 'darkblue' schemes; if none of them is available, do nothing.

Import paths are relative to your $GOPATH and $GOROOT environment variables. For example, with the following $GOPATH:

GOPATH=/home/me/go

Packages located in /home/me/go/src/lib/common and /home/me/go/src/lib/routers are imported respectively as:

import (
    "lib/common"
    "lib/routers"
)

If you mean, you want to scroll through multiple items in your stackpanel, try putting a grid around it. By definition, a stackpanel has infinite length.

So try something like this:

   <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <StackPanel Width="311">
              <TextBlock Text="{Binding A}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}" FontStretch="Condensed" FontSize="28" />
              <TextBlock Text="{Binding B}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
        </StackPanel>
    </Grid>

You could even make this work with a ScrollViewer

The only way you can read a variable amount of data from stdin is using loops. I've always found that the std::getline() function works very well:

std::string line;
while (std::getline(std::cin, line))
{
    std::cout << line << std::endl;
}

By default getline() reads until a newline. You can specify an alternative termination character, but EOF is not itself a character so you cannot simply make one call to getline().

string::npos is a constant (probably -1) representing a non-position. It's returned by method find when the pattern was not found.

Another example to output date and time using zero as a fill character on instances of single digit values: 2017-06-04 18:13:02

#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <ctime>
using namespace std;

int main()
{
    time_t t = time(0);   // Get time now
    struct tm * now = localtime(&t);
    cout.fill('0');
    cout << (now->tm_year + 1900) << '-'
        << setw(2) << (now->tm_mon + 1) << '-'
        << setw(2) << now->tm_mday << ' '
        << setw(2) << now->tm_hour << ':'
        << setw(2) << now->tm_min << ':'
        << setw(2) << now->tm_sec
        << endl;
    return 0;

I like the regex that was published in "Javascript: The Good Parts". Its not too short and not too complex. This page on github also has the JavaScript code that uses it. But it an be adapted for any language. https://gist.github.com/voodooGQ/4057330

I've used Blat ( http://www.blat.net/ ) for many years. It's a simple command line utility that can send email from command line. It's free and opensource.

You can use command like "Blat myfile.txt -to [email protected] -server smtp.domain.com -port 6000"

Here is some other software you can try to send email from command line (I've never used them):
http://caspian.dotconf.net/menu/Software/SendEmail/
http://www.petri.co.il/sendmail.htm
http://www.petri.co.il/software/mailsend105.zip
http://retired.beyondlogic.org/solutions/cmdlinemail/cmdlinemail.htm

Here ( http://www.petri.co.il/send_mail_from_script.htm ) you can find other various way of sending email from a VBS script, plus link to some of the mentioned software

The following VBScript code is taken from that page

Set objEmail = CreateObject("CDO.Message")
objEmail.From = "[email protected]"
objEmail.To = "[email protected]"
objEmail.Subject = "Server is down!"
objEmail.Textbody = "Server100 is no longer accessible over the network."
objEmail.Send

Save the file as something.vbs

Set Msg = CreateObject("CDO.Message")

With Msg

 .To = "[email protected]"
 .From = "[email protected]"
 .Subject = "Hello"
 .TextBody = "Just wanted to say hi."
 .Send

End With

Save the file as something2.vbs

I think these VBS scripts use the windows default mail server, if present. I've not tested these scripts...

You can use the following script:

var findclasses = _doc.DocumentNode.Descendants("div").Where(d => 
    d.Attributes.Contains("class") && d.Attributes["class"].Value.Contains("float")
);

This worked for me: .\mongod --dbpath c:......

NSURL *url = [NSURL URLWithString:@"itms-services://?action=download-manifest&url=https://xxxxxx.com/rest/images/apps/ipa/dev/xyz.plist"]];
[[UIApplication sharedApplication] openURL:url];

openUrl method was deprecated.

[[UIApplication sharedApplication] openURL: url options:@{} completionHandler:nil];

This method latest openUrl method and it will display prompt dialog.The dialog will show

xxxxxx.com would like to install "YOUR_APP_NAME"

this messages. If you click the "install" button application will close and ipa will download.

You could use an extension method to get notified about changed property of an item in a collection in a generic way.

public static class ObservableCollectionExtension
{
    public static void NotifyPropertyChanged<T>(this ObservableCollection<T> observableCollection, Action<T, PropertyChangedEventArgs> callBackAction)
        where T : INotifyPropertyChanged
    {
        observableCollection.CollectionChanged += (sender, args) =>
        {
            //Does not prevent garbage collection says: http://stackoverflow.com/questions/298261/do-event-handlers-stop-garbage-collection-from-occuring
            //publisher.SomeEvent += target.SomeHandler;
            //then "publisher" will keep "target" alive, but "target" will not keep "publisher" alive.
            if (args.NewItems == null) return;
            foreach (T item in args.NewItems)
            {
                item.PropertyChanged += (obj, eventArgs) =>
                {
                    callBackAction((T)obj, eventArgs);
                };
            }
        };
    }
}

public void ExampleUsage()
{
    var myObservableCollection = new ObservableCollection<MyTypeWithNotifyPropertyChanged>();
    myObservableCollection.NotifyPropertyChanged((obj, notifyPropertyChangedEventArgs) =>
    {
        //DO here what you want when a property of an item in the collection has changed.
    });
}

Consider using subtree instead of submodules, it will make your repo users life much easier. You may find more detailed guide in Pro Git book.

This may be a common problem for new users of Matplotlib to draw vertical and horizontal lines. In order to understand this problem, you should be aware that different coordinate systems exist in Matplotlib.

The method axhline and axvline are used to draw lines at the axes coordinate. In this coordinate system, coordinate for the bottom left point is (0,0), while the coordinate for the top right point is (1,1), regardless of the data range of your plot. Both the parameter xmin and xmax are in the range [0,1].

On the other hand, method hlines and vlines are used to draw lines at the data coordinate. The range for xmin and xmax are the in the range of data limit of x axis.

Let's take a concrete example,

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 5, 100)
y = np.sin(x)

fig, ax = plt.subplots()

ax.plot(x, y)
ax.axhline(y=0.5, xmin=0.0, xmax=1.0, color='r')
ax.hlines(y=0.6, xmin=0.0, xmax=1.0, color='b')

plt.show()

It will produce the following plot:

The value for xmin and xmax are the same for the axhline and hlines method. But the length of produced line is different.

This answer is for XAMPP on Ubuntu.

The manual for installation and download is on (site official)

http://www.apachefriends.org/it/xampp-linux.html

After to start XAMPP simply call this command:

sudo /opt/lampp/lampp start

You should now see something like this on your screen:

Starting XAMPP 1.8.1...
LAMPP: Starting Apache...
LAMPP: Starting MySQL...
LAMPP started.

If you have this

Starting XAMPP for Linux 1.8.1...                                                             
XAMPP: Another web server daemon is already running.                                          
XAMPP: Another MySQL daemon is already running.

XAMPP for Linux started

. The solution is

sudo /etc/init.d/apache2 stop
sudo /etc/init.d/mysql stop

And the restast with sudo //opt/lampp/lampp restart

You to fix most of the security weaknesses simply call the following command:

/opt/lampp/lampp security

After the change this file

sudo kate //opt/lampp/etc/extra/httpd-xampp.conf

Find and replace on

I started mongod in cmd,It threw error like C:\data\db\ not found. Created folder then typed mongod opened another cmd typed mongo it worked.

First of all, checked can have a value of checked, or an empty string.

$("input:checkbox").uniform();

$('#check1').live('click', function() {
    $('#check2').attr('checked', 'checked').uniform();
});

I know it has been a while since this was asked, but I learned an alternative yesterday

We all know you can do:

if(o instanceof String) {   // etc

but what if you dont know exactly what type of class it needs to be? you cannot generically do:

if(o instanceof <Class variable>.getClass()) {   

as it gives a compile error.
Instead, here is an alternative - isAssignableFrom()

For example:

public static boolean isASubClass(Class classTypeWeWant, Object objectWeHave) {

    return classTypeWeWant.isAssignableFrom(objectWeHave.getClass())
}

This should do it:

$("label[for=comedyclubs]")

If you have non alphanumeric characters in your id then you must surround the attr value with quotes:

$("label[for='comedy-clubs']")

Just select dogs, then use dog.Breed.BreedName, this should work fine.

If you have a lot of dogs, use DataLoadOptions.LoadWith to reduce the number of db calls.

I won't be explaining how the floats work here (in detail), as this question generally focuses on Why use clear: both; OR what does clear: both; exactly do...

I'll keep this answer simple, and to the point, and will explain to you graphically why clear: both; is required or what it does...

Generally designers float the elements, left or to the right, which creates an empty space on the other side which allows other elements to take up the remaining space.

Why do they float elements?

Elements are floated when the designer needs 2 block level elements side by side. For example say we want to design a basic website which has a layout like below...

</footer>

Note: You might have to add header, footer, aside, section (and other HTML5 elements) as display: block; in your stylesheet for explicitly mentioning that the elements are block level elements.

Explanation:

I have a basic layout, 1 header, 1 side bar, 1 content area and 1 footer.

No floats for header, next comes the aside tag which I'll be using for my website sidebar, so I'll be floating the element to left.

Note: By default, block level element takes up document 100% width, but when floated left or right, it will resize according to the content it holds.

1. Normal Behavior Of Block Level Element
2. Floated Behavior Of Block Level Element

So as you note, the left floated div leaves the space to its right unused, which will allow the div after it to shift in the remaining space.

1. div's will render one after the other if they are NOT floated
2. div will shift beside each other if floated left or right

Ok, so this is how block level elements behave when floated left or right, so now why is clear: both; required and why?

So if you note in the layout demo - in case you forgot, here it is..

I am using a class called .clear and it holds a property called clear with a value of both. So lets see why it needs both.

I've floated aside and section elements to the left, so assume a scenario, where we have a pool, where header is solid land, aside and section are floating in the pool and footer is solid land again, something like this..

So the blue water has no idea what the area of the floated elements are, they can be bigger than the pool or smaller, so here comes a common issue which troubles 90% of CSS beginners: why the background of a container element is not stretched when it holds floated elements. It's because the container element is a POOL here and the POOL has no idea how many objects are floating, or what the length or breadth of the floated elements are, so it simply won't stretch.

1. Normal Flow Of The Document
2. Sections Floated To Left
3. Cleared Floated Elements To Stretch Background Color Of The Container

(Refer ^[Clearfix] section of this answer for neat way to do this. I am using an empty div example intentionally for explanation purpose)

I've provided 3 examples above, 1st is the normal document flow where red background will just render as expected since the container doesn't hold any floated objects.

In the second example, when the object is floated to left, the container element (POOL) won't know the dimensions of the floated elements and hence it won't stretch to the floated elements height.

After using clear: both;, the container element will be stretched to its floated element dimensions.

Another reason the clear: both; is used is to prevent the element to shift up in the remaining space.

Say you want 2 elements side by side and another element below them... So you will float 2 elements to left and you want the other below them.

1. div Floated left resulting in section moving into remaining space
2. Floated div cleared so that the section tag will render below the floated divs

1st Example

2nd Example

Last but not the least, the footer tag will be rendered after floated elements as I've used the clear class before declaring my footer tags, which ensures that all the floated elements (left/right) are cleared up to that point.

Clearfix

Coming to clearfix which is related to floats. As already specified by @Elky, the way we are clearing these floats is not a clean way to do it as we are using an empty div element which is not a div element is meant for. Hence here comes the clearfix.

Think of it as a virtual element which will create an empty element for you before your parent element ends. This will self clear your wrapper element holding floated elements. This element won't exist in your DOM literally but will do the job.

To self clear any wrapper element having floated elements, we can use

.wrapper_having_floated_elements:after {  /* Imaginary class name */
  content: "";
  clear: both;
  display: table;
}

Note the :after pseudo element used by me for that class. That will create a virtual element for the wrapper element just before it closes itself. If we look in the dom you can see how it shows up in the Document tree.

So if you see, it is rendered after the floated child div where we clear the floats which is nothing but equivalent to have an empty div element with clear: both; property which we are using for this too. Now why display: table; and content is out of this answers scope but you can learn more about pseudo element here.

Note that this will also work in IE8 as IE8 supports :after pseudo.

Original Answer:

Most of the developers float their content left or right on their pages, probably divs holding logo, sidebar, content etc., these divs are floated left or right, leaving the rest of the space unused and hence if you place other containers, it will float too in the remaining space, so in order to prevent that clear: both; is used, it clears all the elements floated left or right.

Demonstration:

------------------ ----------------------------------
div1(Floated Left) Other div takes up the space here
------------------ ----------------------------------

Now what if you want to make the other div render below div1, so you'll use clear: both; so it will ensure you clear all floats, left or right

------------------
div1(Floated Left)
------------------
<div style="clear: both;"><!--This <div> acts as a separator--></div>
----------------------------------
Other div renders here now
----------------------------------

The "input" function converts the input you enter as if it were python code. "raw_input" doesn't convert the input and takes the input as it is given. Its advisable to use raw_input for everything. Usage:

>>a = raw_input()
>>5
>>a
>>'5'

DotNetCoders has a starter article on it: http://www.dotnetcoders.com/web/Articles/ShowArticle.aspx?article=50. They talk about how to set up the switches in the configuration file and how to write the code, but it is pretty old (2002).

There's another article on CodeProject: A Treatise on Using Debug and Trace classes, including Exception Handling, but it's the same age.

CodeGuru has another article on custom TraceListeners: Implementing a Custom TraceListener

"...by default == behaves as described above for both predefined and user-defined reference types."

Type T is not necessarily a reference type, so the compiler can't make that assumption.

However, this will compile because it is more explicit:

    bool Compare<T>(T x, T y) where T : class
    {
        return x == y;
    }

Follow up to additional question, "But, in case I'm using a reference type, would the the == operator use the predefined reference comparison, or would it use the overloaded version of the operator if a type defined one?"

I would have thought that == on the Generics would use the overloaded version, but the following test demonstrates otherwise. Interesting... I'd love to know why! If someone knows please share.

namespace TestProject
{
 class Program
 {
    static void Main(string[] args)
    {
        Test a = new Test();
        Test b = new Test();

        Console.WriteLine("Inline:");
        bool x = a == b;
        Console.WriteLine("Generic:");
        Compare<Test>(a, b);

    }


    static bool Compare<T>(T x, T y) where T : class
    {
        return x == y;
    }
 }

 class Test
 {
    public static bool operator ==(Test a, Test b)
    {
        Console.WriteLine("Overloaded == called");
        return a.Equals(b);
    }

    public static bool operator !=(Test a, Test b)
    {
        Console.WriteLine("Overloaded != called");
        return a.Equals(b);
    }
  }
}

Output

Inline: Overloaded == called

Generic:

Follow Up 2

I do want to point out that changing my compare method to

    static bool Compare<T>(T x, T y) where T : Test
    {
        return x == y;
    }

causes the overloaded == operator to be called. I guess without specifying the type (as a where), the compiler can't infer that it should use the overloaded operator... though I'd think that it would have enough information to make that decision even without specifying the type.

This is reviving an old question, but in Python 3, you can just use bytes directly:

>>> bytes([17, 24, 121, 1, 12, 222, 34, 76])
b'\x11\x18y\x01\x0c\xde"L'

if (mysql_num_rows($result)==0) { PERFORM ACTION }

For PHP 5 and 7 and above use mysqli:

if (mysqli_num_rows($result)==0) { PERFORM ACTION }

This gets my vote.

OP assuming query is not returning any error, so this should be one of the way

a less "Math" oriented approach ,but should also work , this way, the < / > test is exposed (maybe more understandable than minimaxing) but it really depends on what you mean by "readable"

function clamp(num, min, max) {
  return num <= min ? min : num >= max ? max : num;
}

Boost is a good suggestion. But if you would like to roll your own, it's not so hard.

Basically you just need a way to build up a graph of objects and then output them to some structured storage format (JSON, XML, YAML, whatever). Building up the graph is as simple as utilizing a marking recursive decent object algorithm and then outputting all the marked objects.

I wrote an article describing a rudimentary (but still powerful) serialization system. You may find it interesting: Using SQLite as an On-disk File Format, Part 2.

Assuming that you only want to read a single line, then use LINE_MAX, which is defined in <limits.h>:

#include <stdio.h>
#include <limits.h>
...
char line[LINE_MAX];
...
if (fgets(line, LINE_MAX, stdin) != NULL) {
...
}
...

I've got php mysql running on IIS - I can use $_SERVER["AUTH_USER"] if I turn on Windows Authentication in IIS -> Authentication and turn off Anonymous authentication (important)

I've used this to get my user and domain:

$user = $_SERVER['AUTH_USER'];

$user will return a value like: DOMAIN\username on our network, and then it's just a case of removing the DOMAIN\ from the string.

This has worked in IE, FF, Chrome, Safari (tested) so far.

YES. This method allowed multiple domain.

VB.NET

response.headers.add("X-Frame-Options", "ALLOW-FROM " & request.urlreferer.tostring())

I also made a library for this. It is fully configurable with a Mustache template. That can:

• Be stored to file, like CHANGELOG.md.
• Be posted to MediaWiki
• Or just be printed to STDOUT

I also made:

• A Gradle plugin
• A Maven plugin
• A Jenkins plugin
• A Bitbucket Server plugin
• A command line tool

Just put instead

<Style TargetType="{x:DataGridCell}" >

But beware that this will target ALL your cells (you're aiming at all the objects of type DataGridCell ) If you want to put a style according to the cell type, I'd recommend you to use a DataTemplateSelector

A good example can be found in Christian Mosers' DataGrid tutorial:

You can use below script.

var obj={1:"a",2:"b",c:"3"};
for (var x=Object.keys(obj),i=0;i<x.length,key=x[i],value=obj[key];i++){
    console.log(key,value);
}

outputs
1 a
2 b
c 3

Well, I don't understand why are you used transaction in case when you make a select.

Transaction is useful when you make changes (add, edit or delete) data from database.

Remove transaction unless you use insert, update or delete statements

With bash

a="The cat sat on the mat"
b=cat
strindex() { 
  x="${1%%$2*}"
  [[ "$x" = "$1" ]] && echo -1 || echo "${#x}"
}
strindex "$a" "$b"   # prints 4
strindex "$a" foo    # prints -1

l = [83, 84, 65, 67, 75]

s = "".join([chr(c) for c in l])

print s

If the starting cell of the range and of the key is static, the solution can be very simple:

Range("A3").Select
Range(Selection, Selection.End(xlToRight)).Select
Range(Selection, Selection.End(xlDown)).Select
Selection.Sort key1:=Range("B3", Range("B3").End(xlDown)), _
order1:=xlAscending, Header:=xlNo

SELECT  CASE WHEN SERVERPROPERTY('EditionID') = -1253826760 THEN 'Desktop'
         WHEN SERVERPROPERTY('EditionID') = -1592396055 THEN 'Express'
         WHEN SERVERPROPERTY('EditionID') = -1534726760 THEN 'Standard'
         WHEN SERVERPROPERTY('EditionID') = 1333529388 THEN 'Workgroup'
         WHEN SERVERPROPERTY('EditionID') = 1804890536 THEN 'Enterprise'
         WHEN SERVERPROPERTY('EditionID') = -323382091 THEN 'Personal'
         WHEN SERVERPROPERTY('EditionID') = -2117995310  THEN 'Developer'
         WHEN SERVERPROPERTY('EditionID') = 610778273  THEN 'Windows Embedded SQL'
         WHEN SERVERPROPERTY('EditionID') = 4161255391   THEN 'Express with Advanced Services'
    END AS 'Edition'; 

Here is how you can check if the token exists:

if (jobject["Result"].SelectToken("Items") != null) { ... }

It checks if "Items" exists in "Result".

This is a NOT working example that causes exception:

if (jobject["Result"]["Items"] != null) { ... }

This will get you a string array of all the resources:

System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames();

First you have to locate the frame id and define it in a WebElement

For ex:- WebElement fr = driver.findElementById("id");

Then switch to the frame using this code:- driver.switchTo().frame("Frame_ID");

An example script:-

WebElement fr = driver.findElementById("theIframe");

driver.switchTo().frame(fr);

Then to move out of frame use:- driver.switchTo().defaultContent();

This is because you didn't make your Facebook app live. For this go to:

Facebook developer page->Select your app->you will see top of the right your live option is disable and click to enable it->It will refer to you in "basic setting section"->You have to add "privacy policy url" and "Terms and services url" also you may select app category->then save the setting.

Note: You can use any blogspot or website to make your privacy policy also terms and condition page.Both I gave same url which worked.

The simplest way is to use the following pattern:

http://[server]/[site]/[ListName]/[Folder]/[SubFolder]

To place a shortcut to a document library:

1. Upload it as *.url file. However, by default, this file type is not allowed.
2. Go to you Document Library settings > Advanced Settings > Allow management of content types. Add the "Link to document" content type to a document library and paste the link

<script type="text/javascript">
    $(document).ready(function () {
        $('.selecctall').click(function (event) {
            if (this.checked) {
                $('.checkbox1').each(function () {
                    this.checked = true;
                });
            } else {
                $('.checkbox1').each(function () {
                    this.checked = false;
                });
            }
        });

    });

</script>

Starting from Java 9, there is a new utility method allowing to create an immutable entry which is Map#entry(Object, Object).

Here is a simple example:

Entry<String, String> entry = Map.entry("foo", "bar");

As it is immutable, calling setValue will throw an UnsupportedOperationException. The other limitations are the fact that it is not serializable and null as key or value is forbidden, if it is not acceptable for you, you will need to use AbstractMap.SimpleImmutableEntry or AbstractMap.SimpleEntry instead.

NB: If your need is to create directly a Map with 0 to up to 10 (key, value) pairs, you can instead use the methods of type Map.of(K key1, V value1, ...).

Not sure about your specific scenario, but you have three options:

1.) use Dictionary<..,..>
2.) create a wrapper class around your values and then you can use List
3.) use Tuple

Try this:

/^(\/([^/]+\/)*)(.*)$/

It will leave the trailing slash on the path, though.

You can use -webkit-border-radius: 0;. Like this:-

-webkit-border-radius: 0;
border: 0;
outline: 1px solid grey;
outline-offset: -1px;

This will give square corners as well as dropdown arrows. Using -webkit-appearance: none; is not recommended as it will turn off all the styling done by Chrome.

The lock accessed is on the object, not on the method. Which variables are accessed within the method is irrelevant.

Adding "synchronized" to the method means the thread running the code must acquire the lock on the object before proceeding. Adding "static synchronized" means the thread running the code must acquire the lock on the class object before proceeding. Alternatively you can wrap code in a block like this:

public void addA() {
    synchronized(this) {
        a++;
    }
}

so that you can specify the object whose lock must be acquired.

If you want to avoid locking on the containing object you can choose between:

• using synchronized blocks that specify different locks
• making a and b atomic (using java.util.concurrent.atomic)

this code works great for me :

echo str_replace(array_keys($data), array_values($data), $query->queryString);

Don't forget to replace $data and $query by your names

The problem you're having is that you're passing incompatible formats from a formatted java.util.Date to construct an instance of java.sql.Date, which don't behave in the same way when using valueOf() since they use different formats.

I also can see that you're aiming to persist hours and minutes, and I think that you'd better change the data type to java.sql.Timestamp, which supports hours and minutes, along with changing your database field to DATETIME or similar (depending on your database vendor).

Anyways, if you want to change from java.util.Date to java.sql.Date, I suggest to use

java.util.Date date = Calendar.getInstance().getTime();
java.sql.Date sqlDate = new java.sql.Date(date.getTime()); 
// ... more code here
prs.setDate(sqlDate);

This answer expounds on John Black's helpful answer, so I will repeat some of his answer content in my answer.

The easiest way to resize a marker seems to be leaving argument 2, 3, and 4 null and scaling the size in argument 5.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|FFFF00",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);  

As an aside, this answer to a similar question asserts that defining marker size in the 2nd argument is better than scaling in the 5th argument. I don't know if this is true.

Leaving arguments 2-4 null works great for the default google pin image, but you must set an anchor explicitly for the default google pin shadow image, or it will look like this:

The bottom center of the pin image happens to be collocated with the tip of the pin when you view the graphic on the map. This is important, because the marker's position property (marker's LatLng position on the map) will automatically be collocated with the visual tip of the pin when you leave the anchor (4th argument) null. In other words, leaving the anchor null ensures the tip points where it is supposed to point.

However, the tip of the shadow is not located at the bottom center. So you need to set the 4th argument explicitly to offset the tip of the pin shadow so the shadow's tip will be colocated with the pin image's tip.

By experimenting I found the tip of the shadow should be set like this: x is 1/3 of size and y is 100% of size.

var pinShadow = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
    null,
    null,
    /* Offset x axis 33% of overall size, Offset y axis 100% of overall size */
    new google.maps.Point(40, 110), 
    new google.maps.Size(120, 110)); 

to give this:

This will do it for you:

function inArray(needle, haystack) {
    var length = haystack.length;
    for(var i = 0; i < length; i++) {
        if(haystack[i] == needle)
            return true;
    }
    return false;
}

I found it in Stack Overflow question JavaScript equivalent of PHP's in_array().

There's a few problems in your code, first your json must look like :

var json = [{
"id" : "1", 
"msg"   : "hi",
"tid" : "2013-05-05 23:35",
"fromWho": "[email protected]"
},
{
"id" : "2", 
"msg"   : "there",
"tid" : "2013-05-05 23:45",
"fromWho": "[email protected]"
}];

Next, you can iterate like this :

for (var key in json) {
if (json.hasOwnProperty(key)) {
  alert(json[key].id);
  alert(json[key].msg);
}
}

And it gives perfect result.

Just use trim if you don't want spaces

"11.01 °C".slice(0,-2).trim()

nib is fine. If in doubt, refer to the Python style guide.

From PEP 8:

Package and Module Names Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.

Since module names are mapped to file names, and some file systems are case insensitive and truncate long names, it is important that module names be chosen to be fairly short -- this won't be a problem on Unix, but it may be a problem when the code is transported to older Mac or Windows versions, or DOS.

When an extension module written in C or C++ has an accompanying Python module that provides a higher level (e.g. more object oriented) interface, the C/C++ module has a leading underscore (e.g. _socket).

To answer this point:

I want Sleep to be an async method so it can await other methods

you can maybe rewrite the Sleep function like this:

private static async Task<int> Sleep(int ms)
{
    Console.WriteLine("Sleeping for " + ms);
    var task = Task.Run(() => Thread.Sleep(ms));
    await task;
    Console.WriteLine("Sleeping for " + ms + "END");
    return ms;
}

static void Main(string[] args)
{
    Console.WriteLine("Starting");

    var task1 = Sleep(2000);
    var task2 = Sleep(1000);

    int totalSlept = task1.Result +task2.Result;

    Console.WriteLine("Slept for " + totalSlept + " ms");
    Console.ReadKey();
}

running this code will output :

Starting
Sleeping for 2000
Sleeping for 1000
*(one second later)*
Sleeping for 1000END
*(one second later)*
Sleeping for 2000END
Slept for 3000 ms

Without having to have another batch file to pass arguments to (and use the argument operators), you can use FOR /F:

FOR /F %%i IN ("..\relativePath") DO echo absolute path: %%~fi

where the i in %%~fi is the variable defined at /F %%i. eg. if you changed that to /F %%a then the last part would be %%~fa.

To do the same thing right at the command prompt (and not in a batch file) replace %% with %...

Empty-ness and "NULL-ness" are two different concepts. As others mentioned the former can be achieved via std::string::empty(), the latter can be achieved with boost::optional<std::string>, e.g.:

boost::optional<string> myStr;
if (myStr) { // myStr != NULL
    // ...
}

In Support Library 27.1.0 and later, Google has introduced new methods requireContext() and requireActivity() methods.

Eg:ContextCompat.getColor(requireContext(), R.color.soft_gray)

Simple ASP.NET MVC subscription form with email textbox would be implemented like that:

Model

The data from the form is mapped to this model

public class SubscribeModel
{
    [Required]
    public string Email { get; set; }
}

View

View name should match controller method name.

@model App.Models.SubscribeModel

@using (Html.BeginForm("Subscribe", "Home", FormMethod.Post))
{
    @Html.TextBoxFor(model => model.Email)
    @Html.ValidationMessageFor(model => model.Email)
    <button type="submit">Subscribe</button>
}

Controller

Controller is responsible for request processing and returning proper response view.

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Subscribe(SubscribeModel model)
    {
        if (ModelState.IsValid)
        {
            //TODO: SubscribeUser(model.Email);
        }

        return View("Index", model);
    }
}

Here is my project structure. Please notice, "Home" views folder matches HomeController name.

You'll need pattern recognition for that. To determine small differences between two images, Hopfield nets work fairly well and are quite easy to implement. I don't know any available implementations, though.

Every day in our office there is an exchange which goes something like this:

"Man, I just love unit tests, I've just been able to make a bunch of changes to the way something works, and then was able to confirm I hadn't broken anything by running the test over it again..."

The details change daily, but the sentiment doesn't. Unit tests and test-driven development (TDD) have so many hidden and personal benefits as well as the obvious ones that you just can't really explain to somebody until they're doing it themselves.

But, ignoring that, here's my attempt!

1. Unit Tests allows you to make big changes to code quickly. You know it works now because you've run the tests, when you make the changes you need to make, you need to get the tests working again. This saves hours.

2. TDD helps you to realise when to stop coding. Your tests give you confidence that you've done enough for now and can stop tweaking and move on to the next thing.

3. The tests and the code work together to achieve better code. Your code could be bad / buggy. Your TEST could be bad / buggy. In TDD you are banking on the chances of both being bad / buggy being low. Often it's the test that needs fixing but that's still a good outcome.

4. TDD helps with coding constipation. When faced with a large and daunting piece of work ahead writing the tests will get you moving quickly.

5. Unit Tests help you really understand the design of the code you are working on. Instead of writing code to do something, you are starting by outlining all the conditions you are subjecting the code to and what outputs you'd expect from that.

6. Unit Tests give you instant visual feedback, we all like the feeling of all those green lights when we've done. It's very satisfying. It's also much easier to pick up where you left off after an interruption because you can see where you got to - that next red light that needs fixing.

7. Contrary to popular belief unit testing does not mean writing twice as much code, or coding slower. It's faster and more robust than coding without tests once you've got the hang of it. Test code itself is usually relatively trivial and doesn't add a big overhead to what you're doing. This is one you'll only believe when you're doing it :)

8. I think it was Fowler who said: "Imperfect tests, run frequently, are much better than perfect tests that are never written at all". I interpret this as giving me permission to write tests where I think they'll be most useful even if the rest of my code coverage is woefully incomplete.

9. Good unit tests can help document and define what something is supposed to do

10. Unit tests help with code re-use. Migrate both your code and your tests to your new project. Tweak the code till the tests run again.

A lot of work I'm involved with doesn't Unit Test well (web application user interactions etc.), but even so we're all test infected in this shop, and happiest when we've got our tests tied down. I can't recommend the approach highly enough.

If you want to switch to a specific database on startup, try

/Applications/Postgres.app/Contents/Versions/9.5/bin/psql vigneshdb;

By default, Postgres runs on the port 5432. If it runs on another, make sure to pass the port in the command line.

/Applications/Postgres.app/Contents/Versions/9.5/bin/psql -p2345 vigneshdb;

By a simple alias, we can make it handy.

Create an alias in your .bashrc or .bash_profile

function psql()
{
    db=vigneshdb
    if [ "$1" != ""]; then
            db=$1
    fi
    /Applications/Postgres.app/Contents/Versions/9.5/bin/psql -p5432 $1
}

Run psql in command line, it will switch to default database; psql anotherdb, it will switch to the db with the name in argument, on startup.

You can also perform Implicit Type Conversions with template literals. Example:

let fruits = ["mango","orange","pineapple","papaya"];

console.log(`My favourite fruits are ${fruits}`);
// My favourite fruits are mango,orange,pineapple,papaya

There's also one important tricky treat of ".PHONY" - when a physical target depends on phony target that depends on another physical target:

TARGET1 -> PHONY_FORWARDER1 -> PHONY_FORWARDER2 -> TARGET2

You'd simply expect that if you updated TARGET2, then TARGET1 should be considered stale against TARGET1, so TARGET1 should be rebuild. And it really works this way.

The tricky part is when TARGET2 isn't stale against TARGET1 - in which case you should expect that TARGET1 shouldn't be rebuild.

This surprisingly doesn't work because: the phony target was run anyway (as phony targets normally do), which means that the phony target was considered updated. And because of that TARGET1 is considered stale against the phony target.

Consider:

all: fileall

fileall: file2 filefwd
    echo file2 file1 >fileall


file2: file2.src
    echo file2.src >file2

file1: file1.src
    echo file1.src >file1
    echo file1.src >>file1

.PHONY: filefwd
.PHONY: filefwd2

filefwd: filefwd2

filefwd2: file1
    @echo "Produced target file1"


prepare:
    echo "Some text 1" >> file1.src
    echo "Some text 2" >> file2.src

You can play around with this:

• first do 'make prepare' to prepare the "source files"
• play around with that by touching particular files to see them updated

You can see that fileall depends on file1 indirectly through a phony target - but it always gets rebuilt due to this dependency. If you change the dependency in fileall from filefwd to file, now fileall does not get rebuilt every time, but only when any of dependent targets is stale against it as a file.

It looks like you want this pluging as it follows your existing code, maybe the plug in js file got left out somewhere.

"Value 1" : "Text 1",
"Value 2" : "Text 2",
"Value 3" : "Text 3"
} 
$("#myselect2").addOption(myOptions, false); 
// use true if you want to select the added options » Run

I had the same problem with PHP 5.2 and solved it with MySQL. Might not be exactly what you're looking for, but this will do the trick and return the number of days:

$datediff_q = $dbh->prepare("SELECT DATEDIFF(:date2, :date1)");
$datediff_q->bindValue(':date1', '2007-03-24', PDO::PARAM_STR);
$datediff_q->bindValue(':date2', '2009-06-26', PDO::PARAM_STR);
$datediff = ($datediff_q->execute()) ? $datediff_q->fetchColumn(0) : false;

More info here http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_datediff

You can specify the -t option (--target) to specify the destination directory. See pip install --help for detailed information. This is the command you need:

pip install -t path_to_your_home package-name

for example, for installing say mxnet, in my $HOME directory, I type:

pip install -t /home/foivos/ mxnet

Looking at the output of the preprocessor is the closest thing to the answer you ask for.

I know you've excluded that (and other ways), but I'm not sure why. You have a specific enough problem to solve, but you have not explained why any of the "normal" methods don't work well for you.

I received a IllegalMonitorStateException while trying to wake up a thread in / from a different class / thread. In java 8 you can use the lock features of the new Concurrency API instead of synchronized functions.

I was already storing objects for asynchronous websocket transactions in a WeakHashMap. The solution in my case was to also store a lock object in a ConcurrentHashMap for synchronous replies. Note the condition.await (not .wait).

To handle the multi threading I used a Executors.newCachedThreadPool() to create a thread pool.

Sample query

SET @runtot:=0;
SELECT
   q1.d,
   q1.c,

       COUNT(*) AS c
    FROM  orders
    WHERE  hasPaid > 0
    GROUP  BY d
    ORDER  BY d) AS q1

Almost all the answers here rely on either (1) require() or (2) installed.packages() to check if a given package is already installed or not.

I'm adding an answer because these are unsatisfactory for a lightweight approach to answering this question.

• require has the side effect of loading the package's namespace, which may not always be desirable
• installed.packages is a bazooka to light a candle -- it will check the universe of installed packages first, then we check if our one (or few) package(s) are "in stock" at this library. No need to build a haystack just to find a needle.

This answer was also inspired by @ArtemKlevtsov's great answer in a similar spirit on a duplicated version of this question. He noted that system.file(package=x) can have the desired affect of returning '' if the package isn't installed, and something with nchar > 1 otherwise.

If we look under the hood of how system.file accomplishes this, we can see it uses a different base function, find.package, which we could use directly:

# a package that exists
find.package('data.table', quiet=TRUE)
# [1] "/Library/Frameworks/R.framework/Versions/4.0/Resources/library/data.table"

# a package that does not
find.package('InstantaneousWorldPeace', quiet=TRUE)
# character(0)

We can also look under the hood at find.package to see how it works, but this is mainly an instructive exercise -- the only ways to slim down the function that I see would be to skip some robustness checks. But the basic idea is: look in .libPaths() -- any installed package pkg will have a DESCRIPTION file at file.path(.libPaths(), pkg), so a quick-and-dirty check is file.exists(file.path(.libPaths(), pkg, 'DESCRIPTION').

You don't need to sort them, just repeatedly partition subsets of them.

The first step is like the first pass of a quicksort. Pick one of the integers, x, and using it make a pass through the array to put all the values less than x to its left and values more than x to its right. Find which side of x has the greatest number of available slots (integers not in the list). This is easily computable by comparing the value of x with its position. Then repeat the partition on the sub-list on that side of x. Then repeat the partition on the sub-sub list with the greatest number of available integers, etc. Total number of compares to get down to an empty range should be about 4 billion, give or take.

Check out yowsup
https://github.com/tgalal/yowsup

Yowsup is a python library that allows you to do all the previous in your own app. Yowsup allows you to login and use the Whatsapp service and provides you with all capabilities of an official Whatsapp client, allowing you to create a full-fledged custom Whatsapp client.

A solid example of Yowsup's usage is Wazapp. Wazapp is full featured Whatsapp client that is being used by hundreds of thousands of people around the world. Yowsup is born out of the Wazapp project. Before becoming a separate project, it was only the engine powering Wazapp. Now that it matured enough, it was separated into a separate project, allowing anyone to build their own Whatsapp client on top of it. Having such a popular client as Wazapp, built on Yowsup, helped bring the project into a much advanced, stable and mature level, and ensures its continuous development and maintaince.

Yowsup also comes with a cross platform command-line frontend called yowsup-cli. yowsup-cli allows you to jump into connecting and using Whatsapp service directly from command line.

I had practically the same problem. in the log file I found this:

Apparently the user table has been corrupted. I replaced it with another copy (user.frm ; user.MYD ; user.MYI in mysql\data\mysql)
and thats works for me.

ps: am using xampp.

IMPORTANT NOTE: You should not concatenate SQL queries unless you trust the user completely. Query concatenation involves risk of SQL Injection being used to take over the world, ...khem, your database.

If you don't want to go into details how to execute query using SqlCommand then you could call the same command line like this:

string userInput = "Brian";
var process = new Process();
var startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = string.Format(@"sqlcmd.exe -S .\PDATA_SQLEXPRESS -U sa -P 2BeChanged! -d PDATA_SQLEXPRESS  
     -s ; -W -w 100 -Q "" SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName,
     tPatDBirthday  FROM  [dbo].[TPatientRaw] WHERE tPatSName = '{0}' """, userInput);

process.StartInfo = startInfo;
process.Start();

Just ensure that you escape each double quote " with ""

Saxon will do this not only for XPath 2.0, but also for XQuery 1.0 and (in the commercial version) 3.0. It doesn't come as a Linux package, but as a jar file. Syntax (which you can easily wrap in a simple script) is

java net.sf.saxon.Query -s:source.xml -qs://element/attribute

2020 UPDATE

Saxon 10.0 includes the Gizmo tool, which can be used interactively or in batch from the command line. For example

java net.sf.saxon.Gizmo -s:source.xml
/>show //element/@attribute
/>quit

It's simple please follow the below step.

1. On IntelliJ press 'Ctrl Alt + S' [ press ctrl alt and S together], this will open 'Setting popup'
2. In Search panel 'left top search 'Theme' keyword.
3. In left panel itself you can see 'Appearance', click on this

4. Right side panel you can see Theme: and drop down with following option

   • Dracula

   • Windows

just select which ever you want and click on apply and Ok.

I hope this may work for you..

I misunderstood question. Sorry. for editor - File->Settings->Editor->Colors &Fonts and choose your scheme.... :)

I think the reason is that in C strings are not primitive types, as tomjen said, think in a string as a char array, so you can not do things like:

switch (char[]) { // ...
switch (int[]) { // ...

This has been really helpful. Here is my implementation for any given table:

def sql_replace(self, tableobject, dictargs):

    #missing check of table object is valid
    primarykeys = [key.name for key in inspect(tableobject).primary_key]

    filterargs = []
    for primkeys in primarykeys:
        if dictargs[primkeys] is not None:
            filterargs.append(getattr(db.RT_eqmtvsdata, primkeys) == dictargs[primkeys])
        else:
            return

    query = select([db.RT_eqmtvsdata]).where(and_(*filterargs))

    if self.r_ExecuteAndErrorChk2(query)[primarykeys[0]] is not None:
        # update
        filter = and_(*filterargs)
        query = tableobject.__table__.update().values(dictargs).where(filter)
        return self.w_ExecuteAndErrorChk2(query)

    else:

Installing from RPM is generally better, because:

• you can install and uninstall (properly) python3.
• the installation time is way faster. If you work in a cloud environment with multiple VMs, compiling python3 on each VMs is not acceptable.

Solution 1: Red Hat & EPEL repositories

Red Hat has added through the EPEL repository:

• Python 3.4 for CentOS 6
• Python 3.6 for CentOS 7

[EPEL] How to install Python 3.4 on CentOS 6

sudo yum install -y epel-release
sudo yum install -y python34

# Install pip3
sudo yum install -y python34-setuptools  # install easy_install-3.4
sudo easy_install-3.4 pip

You can create your virtualenv using pyvenv:

pyvenv /tmp/foo

[EPEL] How to install Python 3.6 on CentOS 7

With CentOS7, pip3.6 is provided as a package :)

sudo yum install -y epel-release
sudo yum install -y python36 python36-pip

You can create your virtualenv using pyvenv:

python3.6 -m venv /tmp/foo

If you use the pyvenv script, you'll get a WARNING:

$ pyvenv-3.6 /tmp/foo
WARNING: the pyenv script is deprecated in favour of `python3.6 -m venv`

Solution 2: IUS Community repositories

The IUS Community provides some up-to-date packages for RHEL & CentOS. The guys behind are from Rackspace, so I think that they are quite trustworthy...

https://ius.io/

Check the right repo for you here:

https://ius.io/setup

[IUS] How to install Python 3.6 on CentOS 6

sudo yum install -y https://repo.ius.io/ius-release-el6.rpm
sudo yum install -y python36u python36u-pip

You can create your virtualenv using pyvenv:

python3.6 -m venv /tmp/foo

[IUS] How to install Python 3.6 on CentOS 7

sudo yum install -y https://repo.ius.io/ius-release-el7.rpm
sudo yum install -y python36u python36u-pip

You can create your virtualenv using pyvenv:

python3.6 -m venv /tmp/foo

The good part is we can make basic maths directly:

let nuts = 7_x000D_
_x000D_
more.innerHTML = `_x000D_
_x000D_
<h2>You collected ${nuts} nuts so far!_x000D_
_x000D_
<hr>_x000D_
_x000D_
Double it, get ${nuts + nuts} nuts!!_x000D_
_x000D_
`

<div id="more"></div>

It became really useful in a factory function:

function nuts(it){_x000D_
  return `_x000D_
    You have ${it} nuts! <br>_x000D_
    Cosinus of your nuts: ${Math.cos(it)} <br>_x000D_
    Triple nuts: ${3 * it} <br>_x000D_
    Your nuts encoded in BASE64:<br> ${btoa(it)}_x000D_
  `_x000D_
}_x000D_
_x000D_
nut.oninput = (function(){_x000D_
  out.innerHTML = nuts(nut.value)_x000D_
})

<h3>NUTS CALCULATOR_x000D_
<input type="number" id="nut">_x000D_
_x000D_
<div id="out"></div>

Let's dissect it. There are three parts:

1. cd -- This is change directory command.
2. /d -- This switch makes cd change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0. (%~d0 Changs active drive, cd %~p0 change the directory).
3. %~dp0 -- This can be dissected further into three parts:
   1. %0 -- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.
   2. %~0 -- The ~ there strips double quotes (") around the expanded argument.
   3. %dp0 -- The d and p there are modifiers of the expansion. The d forces addition of a drive letter and the p adds full path.

In similar situations, I've done well by putting something like the following into /etc/rc.local:

cd /path/to/my/script
./my_script.py &
cd -
echo `date +%Y-%b-%d_%H:%M:%S` > /tmp/ran_rc_local  # check that rc.local ran

This has worked on multiple versions of Fedora and on Ubuntu 14.04 LTS, for both python and perl scripts.

• To remove white spaces:

1) To remove white space everywhere:

df.columns = df.columns.str.replace(' ', '')

2) To remove white space at the beginning of string:

df.columns = df.columns.str.lstrip()

3) To remove white space at the end of string:

df.columns = df.columns.str.rstrip()

4) To remove white space at both ends:

df.columns = df.columns.str.strip()

• To replace white spaces with other characters (underscore for instance):

5) To replace white space everywhere

df.columns = df.columns.str.replace(' ', '_')

6) To replace white space at the beginning:

df.columns = df.columns.str.replace('^ +', '_')

7) To replace white space at the end:

df.columns = df.columns.str.replace(' +$', '_')

8) To replace white space at both ends:

df.columns = df.columns.str.replace('^ +| +$', '_')

All above applies to a specific column as well, assume you have a column named col, then just do:

df[col] = df[col].str.strip()  # or .replace as above

There is no need to use angular http, you can get with js native functions

// you will ned this function to fetch the image blob._x000D_
async function getImage(url, fileName) {_x000D_
     // on the first then you will return blob from response_x000D_
    return await fetch(url).then(r => r.blob())_x000D_
    .then((blob) => { // on the second, you just create a file from that blob, getting the type and name that intend to inform_x000D_
         _x000D_
        return new File([blob], fileName+'.'+   blob.type.split('/')[1]) ;_x000D_
    });_x000D_
}_x000D_
_x000D_
// example url_x000D_
var url = 'https://img.freepik.com/vetores-gratis/icone-realista-quebrado-vidro-fosco_1284-12125.jpg';_x000D_
_x000D_
// calling the function_x000D_
getImage(url, 'your-name-image').then(function(file) {_x000D_
_x000D_
    // with file reader you will transform the file in a data url file;_x000D_
    var reader = new FileReader();_x000D_
    reader.readAsDataURL(file);_x000D_
    reader.onloadend = () => {_x000D_
    _x000D_
    // just putting the data url to img element_x000D_
        document.querySelector('#image').src = reader.result ;_x000D_
    }_x000D_
})

<img src="" id="image"/>

You can also solve this problem by doing this:

//Using an Image as a mask by directly inserting UIImageObject.CGImage causes
//the same inverted display problem. This is solved by saving it to a CGImageRef first.

//CGImageRef image = [UImageObject CGImage];

//CGContextDrawImage(context, boundsRect, image);

Nevermind... Stupid caching.

You can just capture the output and pass it through a filter, something like:

mysql show processlist
    | grep -v '^\+\-\-'
    | grep -v '^| Id'
    | sort -n -k12

The two greps strip out the header and trailer lines (others may be needed if there are other lines not containing useful information) and the sort is done based on the numeric field number 12 (I think that's right).

This one works for your immediate output:

mysql show processlist
    | grep -v '^\+\-\-'
    | grep -v '^| Id'
    | grep -v  '^[0-9][0-9]* rows in set '
    | grep -v '^ '
    | sort -n -k12

You should have header files (.h) that contain the function's declaration, then a corresponding .cpp file that contains the definition. You then include the header file everywhere you need it. Note that the .cpp file that contains the definitions also needs to include (it's corresponding) header file.

// main.cpp
#include "second.h"
int main () {
    secondFunction();
}

// second.h
void secondFunction();

// second.cpp
#include "second.h"
void secondFunction() {
   // do stuff
}

An TextInput must include secureTextEntry={true}, note that the docs of React state that you must not use multiline={true} at the same time, as that combination is not supported.

You can also set textContentType={'password'} to allow the field to retrieve credentials from the keychain stored on your mobile, an alternative way to enter credentials if you got biometric input on your mobile to quickly insert credentials. Such as FaceId on iPhone X or fingerprint touch input on other iPhone models and Android.

 <TextInput value={this.state.password} textContentType={'password'} multiline={false} secureTextEntry={true} onChangeText={(text) => { this._savePassword(text); this.setState({ password: text }); }} style={styles.input} placeholder='Github password' />

There is a very handy function in R edit

new_optim <- edit(optim)

It will open the source code of optim using the editor specified in R's options, and then you can edit it and assign the modified function to new_optim. I like this function very much to view code or to debug the code, e.g, print some messages or variables or even assign them to a global variables for further investigation (of course you can use debug).

If you just want to view the source code and don't want the annoying long source code printed on your console, you can use

invisible(edit(optim))

Clearly, this cannot be used to view C/C++ or Fortran source code.

BTW, edit can open other objects like list, matrix, etc, which then shows the data structure with attributes as well. Function de can be used to open an excel like editor (if GUI supports it) to modify matrix or data frame and return the new one. This is handy sometimes, but should be avoided in usual case, especially when you matrix is big.

I met this problem with typescript but forgot to add ts and tsx suffix to resolve entry.

module.exports = {
  ...
  resolve: {
    extensions: ['.js', '.jsx', '.ts', '.tsx'],
  },
};

This does the job for me

You can use "dd/MM/yyyy" format for using it in DateTime.ParseExact.

Converts the specified string representation of a date and time to its DateTime equivalent using the specified format and culture-specific format information. The format of the string representation must match the specified format exactly.

DateTime date = DateTime.ParseExact("24/01/2013", "dd/MM/yyyy", CultureInfo.InvariantCulture);

Here is a DEMO.

For more informations, check out Custom Date and Time Format Strings

01. Open the page for which you want to get the information.

02. Clear the address bar [where you type the address of the sites]:

and type or copy/paste from below:

javascript:alert(document.lastModified)

03. Press Enter or Go button.

As you mentioned, there could be two below versions of defining a List:

1. List<? extends Map<String, String>>
2. List<?>

2 is very open. It can hold any object type. This may not be useful in case you want to have a map of a given type. In case someone accidentally puts a different type of map, for example, Map<String, int>. Your consumer method might break.

In order to ensure that List can hold objects of a given type, Java generics introduced ? extends. So in #1, the List can hold any object which is derived from Map<String, String> type. Adding any other type of data would throw an exception.

To use aliases on eloquent models modify your code like this:

Item
    ::from( 'items as items_alias' )
    ->join( 'attachments as att', DB::raw( 'att.item_id' ), '=', DB::raw( 'items_alias.id' ) )
    ->select( DB::raw( 'items_alias.*' ) )
    ->get();

This will automatically add table prefix to table names and returns an instance of Items model. not a bare query result. Adding DB::raw prevents laravel from adding table prefixes to aliases.

I believe using --no-index is what you're looking for:

git diff [<options>] --no-index [--] <path> <path>

as mentioned in the git manual:

This form is to compare the given two paths on the filesystem. You can omit the --no-index option when running the command in a working tree controlled by Git and at least one of the paths points outside the working tree, or when running the command outside a working tree controlled by Git.

I had the same problem, although all required packages were installed. I closed down Eclipse, ran monitor.bat in the \android-sdks\tools\ folder, opened the AVD Manager from there, and I was able the create virtual devices here.

Set the following two environment variables:

NVIDIA_VISIBLE_DEVICES=$gpu_id
CUDA_VISIBLE_DEVICES=0

where gpu_id is the ID of your selected GPU, as seen in the host system's nvidia-smi (a 0-based integer) that will be made available to the guest system (e.g. to the Docker container environment).

You can verify that a different card is selected for each value of gpu_id by inspecting Bus-Id parameter in nvidia-smi run in a terminal in the guest system).

More info

This method based on NVIDIA_VISIBLE_DEVICES exposes only a single card to the system (with local ID zero), hence we also hard-code the other variable, CUDA_VISIBLE_DEVICES to 0 (mainly to prevent it from defaulting to an empty string that would indicate no GPU).

Note that the environmental variable should be set before the guest system is started (so no chances of doing it in your Jupyter Notebook's terminal), for instance using docker run -e NVIDIA_VISIBLE_DEVICES=0 or env in Kubernetes or Openshift.

If you want GPU load-balancing, make gpu_id random at each guest system start.

If setting this with python, make sure you are using strings for all environment variables, including numerical ones.

You can verify that a different card is selected for each value of gpu_id by inspecting nvidia-smi's Bus-Id parameter (in a terminal run in the guest system).

The accepted solution based on CUDA_VISIBLE_DEVICES alone does not hide other cards (different from the pinned one), and thus causes access errors if you try to use them in your GPU-enabled python packages. With this solution, other cards are not visible to the guest system, but other users still can access them and share their computing power on an equal basis, just like with CPU's (verified).

This is also preferable to solutions using Kubernetes / Openshift controlers (resources.limits.nvidia.com/gpu), that would impose a lock on the allocated card, removing it from the pool of available resources (so the number of containers with GPU access could not exceed the number of physical cards).

This has been tested under CUDA 8.0, 9.0 and 10.1 in docker containers running Ubuntu 18.04 orchestrated by Openshift 3.11.
