This might not be the answer you're looking for, but I don't have a better way for downloading DB from phone. What I will suggest is make sure you're using this mini-DDMS. It will be super hidden though if you don't click the very small camoflage box at the very bottom left of program. (tried to hover over it otherwise you might miss it.)

Also the drop down that says no filters (top right). It literally has a ton of different ways you can monitor different process/apps by PPID, name, and a lot more. I've always used this to monitor phone, but keep in mind I'm not doing the type of dev work that needs to be 120% positive the database isn't doing something out of the ordinary.

Hope it helps

As far as I know, currently (Android Studio 2.3) there is no way to do this.

As per Android Studio documentation:

"Note: Only one debugger can be connected to your device at a time."

When you attempt to connect Android Device Monitor it disconnects Android Studio's debug session and vice versa, when you attempt to connect Android Studio's debugger, it disconnects Android Device Monitor.

Fortunately the new version of Android Studio (3.0) will feature a Device File Explorer that will allow you to pull files from within Android Studio without the need to open the Android Device Monitor which should resolve the problem.

You can use this command,

adb shell dumpsys activity

You can find current activity name in activity stack.

I've used this one with good success - I don't remember where I got it from

Updated for Redis 2.8 and above

As noted in the comments of previous answers to this question, KEYS is a potentially dangerous command since your Redis server will be unavailable to do other operations while it serves it. Another risk with KEYS is that it can consume (dependent on the size of your keyspace) a lot of RAM to prepare the response buffer, thus possibly exhausting your server's memory.

Version 2.8 of Redis had introduced the SCAN family of commands that are much more polite and can be used for the same purpose.

The CLI also provides a nice way to work with it:

$ redis-cli --scan --pattern '*'

If the required data is not too large (limits I don´t know, would depend on a lot of things), you might also download the data (in XML, JSON, whatever) from a website/webapp. AFter receiving, execute the SQL statements using the received data creating your tables and inserting the data.

If your mobile app contains lots of data, it might be easier later on to update the data in the installed apps with more accurate data or changes.

What about creating an extension method?

public static class NullableExtensions
{
    public static bool TryParse(this DateTime? dateTime, string dateString, out DateTime? result)
    {
        DateTime tempDate;
        if(! DateTime.TryParse(dateString,out tempDate))
        {
            result = null;
            return false;
        }

        result = tempDate;
        return true;

    }
}

Just as another option if you want to print only the key (doesn't write the .env file) you can use:

php artisan key:generate --show

bw.newLine(); cannot ensure compatibility with all systems.

If you are sure it is going to be opened in windows, you can format it to windows newline.

If you are already using native unix commands, try unix2dos and convert teh already generated file to windows format and then send the mail.

If you are not using unix commands and prefer to do it in java, use ``bw.write("\r\n")` and if it does not complicate your program, have a method that finds out the operating system and writes the appropriate newline.

There are three methods that you can use to return an exit code from a console application.

1. Modify the Main method in your application so that it returns an int instead of void (a function that returns an Integer instead of Sub in VB.Net) and then return the exit code from that method.
2. Set the Environment.ExitCode property to the exit code. Note that method 1. takes precedence - if the Main method returns anything other than void (is a Sub in VB.Net) then the value of this property will be ignored.
3. Pass the exit code to the Environment.Exit method. This will terminate the process immediately as opposed to the other two methods.

An important standard that should be observed is that 0 represents 'Success'.

On a related topic, consider using an enumeration to define the exit codes that your application is going to return. The FlagsAttribute will allow you to return a combination of codes.

Also, ensure that your application is compiled as a 'Console Application'.

From Java 1.5 it's always a good Idea to consider java.util.concurrent package. They are the state of the art locking mechanism in java right now. The synchronize mechanism is more heavyweight that the java.util.concurrent classes.

The example would look something like this:

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class Sample {

    private final Lock lock = new ReentrantLock();

    private String message = null;

    public void newmsg(String msg) {
        lock.lock();
        try {
            message = msg;
        } finally {
            lock.unlock();
        }
    }

    public String getmsg() {
        lock.lock();
        try {
            String temp = message;
            message = null;
            return temp;
        } finally {
            lock.unlock();
        }
    }
}

For those working in Titanium Studio, the item is a little different: It's under the "Titanium Studio" Themes tab.

The color to change is the "Selection" one in the top right.

That's because you created a Web Site instead of a Web Application. The cs/vb files can only be seen in a Web Application, but in a website you can't have a separate cs/vb file.

Edit: In the website you can add a cs file behavior like..

<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>

~/Global.asax.cs:

namespace ApplicationName
{
    public partial class MyApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
        }
    }
}

On MacOSX lldb needs to be code signed. The Debug and Release builds are set to code sign using a code signing certificate named lldb_codesign.

If you don't have one yet you will need to:
- Launch /Applications/Utilities/Keychain Access.app

- In Keychain Access select the "login" keychain in the "Keychains"
  list in the upper left hand corner of the window.

- Select the following menu item:

    Keychain Access->Certificate Assistant->Create a Certificate...

- Set the following settings

    Name = lldb_codesign
    Identity Type = Self Signed Root
    Certificate Type = Code Signing

- Click Continue
- Click Continue
- Click Done
- Click on the "My Certificates"
- Double click on your new lldb_codesign certificate
- Turn down the "Trust" disclosure triangle

    Change:
        When using this certificate: Always Trust

- Enter your login password to confirm and make it trusted

The next steps are necessary on SnowLeopard, but are probably because of a bug
how Keychain Access makes certificates.

- Option-drag the new lldb_codesign certificate from the login keychain to
  the System keychain in the Keychains pane of the main Keychain Access window
  to make a copy of this certificate in the System keychain.  You'll have to
  authorize a few more times, set it to be "Always trusted" when asked.
- Switch to the System keychain, and drag the copy of lldb_codesign you just
  made there onto the desktop.
- Switch to Terminal, and run the following:

sudo security add-trust -d -r trustRoot -p basic -p codeSign -k /Library/Keychains/System.keychain ~/Desktop/lldb_codesign.cer

- Right click on the "lldb_codesign" certificate in the "System" keychain (NOT
  "login", but the one in "System"), and select "Delete" to delete it from
  the "System" keychain.
- Reboot
- Clean and rebuild lldb and you should be able to debug.

That should do it.

[Note: - lldb is used in mac as gdb.]

Contents are shallow copied.

So if the original dict contains a list or another dictionary, modifying one them in the original or its shallow copy will modify them (the list or the dict) in the other.

There is nothing wrong with the example you have given. But i must say i believe it's not efficient to store function definitions in a cpp file. I only understand the need to separate the function's declaration and definition.

When used together with explicit class instantiation, the Boost Concept Check Library (BCCL) can help you generate template function code in cpp files.

This is an improve of @ComFreek ans:

<form id="myform">
  <!-- form elements -->
  <a href="javascript:;" onclick="document.getElementById('myform').submit()">Submit</a>
</form>

So the will not trigger action and reload your page. Specially if your are developing with a framework with SPA.

From the Python glossary:

An object is hashable if it has a hash value which never changes during its lifetime (it needs a __hash__() method), and can be compared to other objects (it needs an __eq__() or __cmp__() method). Hashable objects which compare equal must have the same hash value.

Hashability makes an object usable as a dictionary key and a set member, because these data structures use the hash value internally.

All of Python’s immutable built-in objects are hashable, while no mutable containers (such as lists or dictionaries) are. Objects which are instances of user-defined classes are hashable by default; they all compare unequal, and their hash value is their id().

mvn install primary jobs are to 1)Download The Dependencies and 2)Build The Project

while job 1 is nowadays taken care by IDs like intellij (they download for any dependency at POM)

mvn install is majorly now used for job 2.

Another use that I've been putting to good purpose is fetching data from multiple sources. In the example below, I'm fetching multiple, independent JSON schema objects used in an existing application for validation between a client and a REST server. In this case, I don't want the browser-side application to start loading data before it has all the schemas loaded. $.when.apply().then() is perfect for this. Thank to Raynos for pointers on using then(fn1, fn2) to monitor for error conditions.

fetch_sources = function (schema_urls) {
    var fetch_one = function (url) {
            return $.ajax({
                url: url,
                data: {},
                contentType: "application/json; charset=utf-8",
                dataType: "json",
            });
        }
    return $.map(schema_urls, fetch_one);
}

var promises = fetch_sources(data['schemas']);
$.when.apply(null, promises).then(

function () {
    var schemas = $.map(arguments, function (a) {
        return a[0]
    });
    start_application(schemas);
}, function () {
    console.log("FAIL", this, arguments);
});     

You are looking for the OS native module for Node.js:

v4: https://nodejs.org/dist/latest-v4.x/docs/api/os.html#os_os_platform

or v5 : https://nodejs.org/dist/latest-v5.x/docs/api/os.html#os_os_platform

os.platform()

Returns the operating system platform. Possible values are 'darwin', 'freebsd', 'linux', 'sunos' or 'win32'. Returns the value of process.platform.

Simple solution for downloading a file from the server:

protected void btnDownload_Click(object sender, EventArgs e)
        {
            string FileName = "Durgesh.jpg"; // It's a file name displayed on downloaded file on client side.

            System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
            response.ClearContent();
            response.Clear();
            response.ContentType = "image/jpeg";
            response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ";");
            response.TransmitFile(Server.MapPath("~/File/001.jpg"));
            response.Flush();
            response.End();
        }

A more direct equivalent to a instanceof B is

B.class.isInstance(a)

This works (returns false) when a is null too.

There are a several ways of declaring variables in SQL*Plus scripts.

The first is to use VAR, to declare a bind variable. The mechanism for assigning values to a VAR is with an EXEC call:

SQL> var name varchar2(20)
SQL> exec :name := 'SALES'

PL/SQL procedure successfully completed.

SQL> select * from dept
  2  where dname = :name
  3  /

    DEPTNO DNAME          LOC
---------- -------------- -------------
        30 SALES          CHICAGO

SQL>

A VAR is particularly useful when we want to call a stored procedure which has OUT parameters or a function.

Alternatively we can use substitution variables. These are good for interactive mode:

SQL> accept p_dno prompt "Please enter Department number: " default 10
Please enter Department number: 20
SQL> select ename, sal
  2  from emp
  3  where deptno = &p_dno
  4  /
old   3: where deptno = &p_dno
new   3: where deptno = 20

ENAME             SAL
---------- ----------
CLARKE            800
ROBERTSON        2975
RIGBY            3000
KULASH           1100
GASPAROTTO       3000

SQL>

When we're writing a script which calls other scripts it can be useful to DEFine the variables upfront. This snippet runs without prompting me to enter a value:

SQL> def p_dno = 40
SQL> select ename, sal
  2  from emp
  3  where deptno = &p_dno
  4  /
old   3: where deptno = &p_dno
new   3: where deptno = 40

no rows selected

SQL>

Finally there's the anonymous PL/SQL block. As you see, we can still assign values to declared variables interactively:

SQL> set serveroutput on size unlimited
SQL> declare
  2      n pls_integer;
  3      l_sal number := 3500;
  4      l_dno number := &dno;
  5  begin
  6      select count(*)
  7      into n
  8      from emp
  9      where sal > l_sal
 10      and deptno = l_dno;
 11      dbms_output.put_line('top earners = '||to_char(n));
 12  end;
 13  /
Enter value for dno: 10
old   4:     l_dno number := &dno;
new   4:     l_dno number := 10;
top earners = 1

PL/SQL procedure successfully completed.

This is explained quite well in the Python documentation:

repr(object): Return a string containing a printable representation of an object. This is the same value yielded by conversions (reverse quotes). It is sometimes useful to be able to access this operation as an ordinary function. For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval(), otherwise the representation is a string enclosed in angle brackets that contains the name of the type of the object together with additional information often including the name and address of the object. A class can control what this function returns for its instances by defining a __repr__() method.

So what you're seeing here is the default implementation of __repr__, which is useful for serialization and debugging.

u can use this:

protected void btnConfirm_Click(object sender, EventArgs e)
{
  Response.Redirect("Confirm.aspx");
}

I did some development with Mifare Classic (ISO 14443A) cards about 7-8 years ago. You can read and write to all sectors of the card, IIRC the only data you can't change is the serial number. Back then we used a proprietary library from Philips Semiconductors. The command interface to the card was quite alike the ISO 7816-4 (used with standard Smart Cards).

I'd recomment that you look at the OpenPCD platform if you are into development.

This is also of interest regarding the cryptographic functions in some RFID cards.

By subquery, it should work:

    SELECT distinct(Category) from MonitoringJob  where Category in(select Category from MonitoringJob order by CreationDate desc);

Like others suggested you are better off using collection. If you however for some reason must stick to array then Apache Commons ArrayUtils may help:

int[] series = {4,2};
series = ArrayUtils.add(series, 3); // series is now {4,2,3}
series = ArrayUtils.add(series, 4); // series is now {4,2,3,4};

Note that the add method creates a new array, copies the given array and appends the new element at the end, which may have impact on performance.

This is defined in the ECMAScript specification Section 7.3.19 Step 3: If Type(O) is not Object, return false.

In other word, if the Obj in Obj instanceof Callable is not an object, the instanceof will short-circuit to false directly.

The script in How to get rid of the white margin in MATLAB's saveas or print outputs does what you want.

Make your figure boundaries tight:

ti = get(gca,'TightInset')
set(gca,'Position',[ti(1) ti(2) 1-ti(3)-ti(1) 1-ti(4)-ti(2)]);

... if you directly do saveas (or print), MATLAB will still add the annoying white space. To get rid of them, we need to adjust the ``paper size":

set(gca,'units','centimeters')
pos = get(gca,'Position');
ti = get(gca,'TightInset');

set(gcf, 'PaperUnits','centimeters');
set(gcf, 'PaperSize', [pos(3)+ti(1)+ti(3) pos(4)+ti(2)+ti(4)]);
set(gcf, 'PaperPositionMode', 'manual');
set(gcf, 'PaperPosition',[0 0 pos(3)+ti(1)+ti(3) pos(4)+ti(2)+ti(4)]);

Easiest implementation.

<script>
    $( ".selectpicker" ).change(function() {
        alert( "Handler for .change() called." );
    });
</script>

If you need to center a text in a link this will do the trick:

div {_x000D_
  display: flex;_x000D_
_x000D_
  width: 200px;_x000D_
  height: 80px;_x000D_
  background-color: yellow;_x000D_
}_x000D_
_x000D_
a {_x000D_
  display: flex;_x000D_
  align-items: center;_x000D_
  justify-content: center;_x000D_
  text-align: center; /* only important for multiple lines */_x000D_
_x000D_
  padding: 0 20px;_x000D_
  background-color: silver;_x000D_
  border: 2px solid blue;_x000D_
}

<div>_x000D_
  <a href="#">text</a>_x000D_
  <a href="#">text with two lines</a>_x000D_
</div>

If it's sufficient to use the following criteria to locate the profile:

<key>Name</key>
<string>iOS Team Provisioning Profile: *</string>

you can scan the directory using awk. This one-liner will find the first file that contains the name starting with "iOS Team".

awk 'BEGIN{e=1;pat="<string>"tolower("iOS Team")}{cur=tolower($0);if(cur~pat &&prev~/<key>name<\/key>/){print FILENAME;e=0;exit};if($0!~/^\s*$/)prev=cur}END{exit e}' *

Here's a script that also returns the first match, but is easier to work with.

#!/bin/bash

if [ $# != 1 ] ; then
    echo Usage: $0 \<start of provisioning profile name\>
    exit 1
fi

read -d '' script << 'EOF'
BEGIN {
    e = 1
    pat = "<string>"tolower(prov)
}
{
    cur = tolower($0)
    if (cur ~ pat && prev ~ /<key>name<\\/key>/) {
        print FILENAME
        e = 0
        exit
    }
    if ($0 !~ /^\s*$/) {
        prev = cur
    }
}
END {
 exit e
}
EOF


awk -v "prov=$1" "$script" *

It can be called from within the profiles directory, $HOME/Library/MobileDevice/Provisioning Profiles:

~/findprov "iOS Team"

To use the script, save it to a suitable location and remember to set the executable mode; e.g., chmod ugo+x

Since this is a pretty old question, and this method hasn't been added (aside from the system() call function) I guess it would be useful to include creating the shell script with the C binary itself. The shell code will be housed inside the file.c source file. Here is an example of code:

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

#define SHELLSCRIPT "\
#/bin/bash \n\
echo -e \"\" \n\
echo -e \"This is a test shell script inside C code!!\" \n\
read -p \"press <enter> to continue\" \n\
clear\
"

int main() {

system(SHELLSCRIPT);
return 0;
}

Basically, in a nutshell (pun intended), we are defining the script name, fleshing out the script, enclosing them in double quotes (while inserting proper escapes to ignore double quotes in the shell code), and then calling that script's name, which in this example is SHELLSCRIPT using the system() function in main().

You can press I twice to interrupt the kernel.

This only works if you're in Command mode. If not already enabled, press Esc to enable it.

While some of these answers are pretty good, I feel like none actually answered the OP's original constraint: selecting particular files from particular branches. This solution does that, but it may be tedious if there are many files.

Let’s say you have the master, exp1, and exp2 branches. You want to merge one file from each of the experimental branches into master. I would do something like this:

git checkout master
git checkout exp1 path/to/file_a
git checkout exp2 path/to/file_b

# Save these files as a stash
git stash

# Merge stash with master
git merge stash

This will give you in-file diffs for each of the files you want. Nothing more. Nothing less. It's useful you have radically different file changes between versions --in my case, changing an application from Ruby on Rails 2 to Ruby on Rails 3.

This will merge files, but it does a smart merge. I wasn't able to figure out how to use this method to get in-file diff information (maybe it still will for extreme differences. Annoying small things like whitespace get merged back in unless you use the -s recursive -X ignore-all-space option)

Like this, using .limit():

var q = models.Post.find({published: true}).sort('date', -1).limit(20);
q.execFind(function(err, posts) {
  // `posts` will be of length 20
});

The issue was in fact that one of the properties was a relation to another table. I changed my LINQ query so that it could get the same data from a different method without needing to load the entire table.

Thank you all for your help!

You could make use of the Javascript DOM API. In particular, look at the createElement() method.

You could create a re-usable function that will create an image like so...

function show_image(src, width, height, alt) {
    var img = document.createElement("img");
    img.src = src;
    img.width = width;
    img.height = height;
    img.alt = alt;

    // This next line will just add it to the <body> tag
    document.body.appendChild(img);
}

Then you could use it like this...

<button onclick=
    "show_image('http://google.com/images/logo.gif', 
                 276, 
                 110, 
                 'Google Logo');">Add Google Logo</button> 

See a working example on jsFiddle: http://jsfiddle.net/Bc6Et/

@littleguy23 That is correct, but you don't want to do it to multi select. So just a small change to the code:

$(document).ready(function() {
    // Select - Single
    $('select:not([multiple])').material_select();
});

you are looking for this:

a:visited{
  color:blue;
}

Links have several states you can alter... the way I remember them is LVHFA (Lord Vader's Handle Formerly Anakin)

Each letter stands for a pseudo class: (Link,Visited,Hover,Focus,Active)

a:link{
  color:blue;
}
a:visited{
  color:purple;
}
a:hover{
  color:orange;
}
a:focus{
  color:green;
}
a:active{
  color:red;
}

If you want the links to always be blue, just change all of them to blue. I would note though on a usability level, it would be nice if the mouse click caused the color to change a little bit (even if just a lighter/darker blue) to help indicate that the link was actually clicked (this is especially important in a touchscreen interface where you're not always sure the click was actually registered)

If you have different types of links that you want to all have the same color when clicked, add a class to the links.

a.foo, a.foo:link, a.foo:visited, a.foo:hover, a.foo:focus, a.foo:active{
  color:green;
}
a.bar, a.bar:link, a.bar:visited, a.bar:hover, a.bar:focus, a.bar:active{
  color:orange;
}

It should be noted that not all browsers respect each of these options ;-)

Python is neither pass-by-value nor pass-by-reference. It's more of "object references are passed by value" as described here:

1. Here's why it's not pass-by-value. Because

   def append(list):
       list.append(1)
   
   list = [0]
   reassign(list)
   append(list)
   

returns [0,1] showing that some kind of reference was clearly passed as pass-by-value does not allow a function to alter the parent scope at all.

Looks like pass-by-reference then, hu? Nope.

2. Here's why it's not pass-by-reference. Because

   def reassign(list):
     list = [0, 1]
   
   list = [0]
   reassign(list)
   print list
   

returns [0] showing that the original reference was destroyed when list was reassigned. pass-by-reference would have returned [0,1].

For more information look here:

If you want your function to not manipulate outside scope, you need to make a copy of the input parameters that creates a new object.

from copy import copy

def append(list):
  list2 = copy(list)
  list2.append(1)
  print list2

list = [0]
append(list)
print list

I had a similarly strange problem with a file from the program e-prime (edat -> SPSS conversion), but then I discovered that there are many additional encodings you can use. this did the trick for me:

tbl <- read.delim("dir/file.txt", fileEncoding="UCS-2LE")

You are correct - here is a fully working example - you'll see that var result is implicitly a string because the return type is specified on the greet() function. Change the type to number and you'll get warnings.

class Greeter {
    greeting: string;
    constructor (message: string) {
        this.greeting = message;
    }
    greet() : string {
        return "Hello, " + this.greeting;
    }
} 

var greeter = new Greeter("Hi");
var result = greeter.greet();

Here is the number example - you'll see red squiggles in the playground editor if you try this:

greet() : number {
    return "Hello, " + this.greeting;
}

perl -lne '$x += $_; END { print $x; }' < infile.txt

navigate to the folder where you have installed your kibana if you have used yum to install kibana it will be placed in following location by default

Any time you do calculations with doubles, this can happen. This code would give you 877.85:

double answer = Math.round(dCommission * 100000) / 100000.0;

If someone is using @Sceduled this might work for you.

@Scheduled(cron = "${name-of-the-cron:0 0/30 * * * ?}")

This worked for me.

In Python 3.+ with the Signature object at hand, an easy way to get a mapping between argument names to values, is using the Signature's bind() method!

For example, here is a decorator for printing a map like that:

import inspect

def decorator(f):
    def wrapper(*args, **kwargs):
        bound_args = inspect.signature(f).bind(*args, **kwargs)
        bound_args.apply_defaults()
        print(dict(bound_args.arguments))

        return f(*args, **kwargs)

    return wrapper

@decorator
def foo(x, y, param_with_default="bars", **kwargs):
    pass

foo(1, 2, extra="baz")
# This will print: {'kwargs': {'extra': 'baz'}, 'param_with_default': 'bars', 'y': 2, 'x': 1}

If you are running PHP on Apache then you can use the enviroment variable called DOCUMENT_ROOT. This means that the path is dynamic, and can be moved between servers without messing about with the code.

<?php
  $fileLocation = getenv("DOCUMENT_ROOT") . "/myfile.txt";
  $file = fopen($fileLocation,"w");
  $content = "Your text here";
  fwrite($file,$content);
  fclose($file);
?>

/* Most Accurate Setting if you only want
   to do this with CSS Pseudo Element */
p:before { 
   content: "\00a0";
   padding-right: 5px; /* If you need more space b/w contents */
}

See the correct way with your example:

<div ng-if="!test.view">1</div>
<div ng-if="!!test.view">2</div>

IPv4 uses 32 bits, in the form of:

255.255.255.255

I suppose it depends on your datatype, whether you're just storing as a string with a CHAR type or if you're using a numerical type.

IPv6 uses 128 bits. You won't have IPs longer than that unless you're including other information with them.

IPv6 is grouped into sets of 4 hex digits seperated by colons, like (from wikipedia):

2001:0db8:85a3:0000:0000:8a2e:0370:7334

You're safe storing it as a 39-character long string, should you wish to do that. There are other shorthand ways to write addresses as well though. Sets of zeros can be truncated to a single 0, or sets of zeroes can be hidden completely by a double colon.

Java date libraries are notoriously broken. I would advise to use Joda Time. It will take care of leap year, time zone and so on for you.

Minimal working example:

import java.util.Scanner;
import org.joda.time.DateTime;
import org.joda.time.Days;
import org.joda.time.LocalDate;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;

public class DateTestCase {

    public static void main(String[] args) {

        System.out.print("Insert first date: ");
        Scanner s = new Scanner(System.in);
        String firstdate = s.nextLine();
        System.out.print("Insert second date: ");
        String seconddate = s.nextLine();

        // Formatter
        DateTimeFormatter dateStringFormat = DateTimeFormat
                .forPattern("dd MM yyyy");
        DateTime firstTime = dateStringFormat.parseDateTime(firstdate);
        DateTime secondTime = dateStringFormat.parseDateTime(seconddate);
        int days = Days.daysBetween(new LocalDate(firstTime),
                                    new LocalDate(secondTime)).getDays();
        System.out.println("Days between the two dates " + days);
    }
}

>>> mylist = [["%s,%s"%(i,j) for j in range(columns)] for i in range(rows)]
>>> mylist
[['0,0', '0,1', '0,2'], ['1,0', '1,1', '1,2'], ['2,0', '2,1', '2,2']]
>>> zip(*mylist)
[('0,0', '1,0', '2,0'), ('0,1', '1,1', '2,1'), ('0,2', '1,2', '2,2')]
>>> sum(zip(*mylist),())
('0,0', '1,0', '2,0', '0,1', '1,1', '2,1', '0,2', '1,2', '2,2')

To get the "pseudo class", you can get the constructor function, by

obj.constructor

assuming the constructor is set correctly when you do the inheritance -- which is by something like:

Dog.prototype = new Animal();
Dog.prototype.constructor = Dog;

and these two lines, together with:

var woofie = new Dog()

will make woofie.constructor point to Dog. Note that Dog is a constructor function, and is a Function object. But you can do if (woofie.constructor === Dog) { ... }.

If you want to get the class name as a string, I found the following working well:

http://blog.magnetiq.com/post/514962277/finding-out-class-names-of-javascript-objects

function getObjectClass(obj) {
    if (obj && obj.constructor && obj.constructor.toString) {
        var arr = obj.constructor.toString().match(
            /function\s*(\w+)/);

        if (arr && arr.length == 2) {
            return arr[1];
        }
    }

    return undefined;
}

It gets to the constructor function, converts it to string, and extracts the name of the constructor function.

Note that obj.constructor.name could have worked well, but it is not standard. It is on Chrome and Firefox, but not on IE, including IE 9 or IE 10 RTM.

Perm Gen stands for permanent generation which holds the meta-data information about the classes.

1. Suppose if you create a class name A, it's instance variable will be stored in heap memory and class A along with static classloaders will be stored in permanent generation.
2. Garbage collectors will find it difficult to clear or free the memory space stored in permanent generation memory. Hence it is always recommended to keep the permgen memory settings to the advisable limit.
3. JAVA8 has introduced the concept called meta-space generation, hence permgen is no longer needed when you use jdk 1.8 versions.

I could see $.ajax is removed from jQuery slim 3.2.1

From the jQuery docs

You can also use the slim build, which excludes the ajax and effects modules

Below is the comment from the slim version with the features removed

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

In Perl, if you don't want to set the $/ variable and use chomp() you can also do:

$var =~ /\r\n//g;

A Stacked bar chart should suffice:

Setup data as follows

Name    Start       End         Duration (End - Start)
Fred    1/01/1981   1/06/1985    1612   
Bill    1/07/1985   1/11/2000    5602  
Joe     1/01/1980   1/12/2001    8005  
Jim     1/03/1999   1/01/2000    306  

1. Plot Start and Duration as a stacked bar chart
2. Set the X-Axis minimum to the desired start date
3. Set the Fill Colour of thestart range to no fill
4. Set the Fill of individual bars to suit

(example prepared in Excel 2010)

For another as Latin languages for example Cyrillic you can use something like this:

FileReader fr = new FileReader("src/text.txt", StandardCharsets.UTF_8);

and be sure that your .txt file is saved with UTF-8 (but not as default ANSI) format. Cheers!

FYI - jQuery Users

jQuery's each(callback) method uses for( ; ; ) loop by default, and will use for( in ) only if the length is undefined.

Therefore, I would say it is safe to assume the correct order when using this function.

Example:

$(['a','b','c']).each(function() {
    alert(this);
});
//Outputs "a" then "b" then "c"

The downside of using this is that if you're doing some non UI logic, your functions will be less portable to other frameworks. The each() function is probably best reserved for use with jQuery selectors and for( ; ; ) might be advisable otherwise.

If the numeric values are seq indexes, then we could have simpler ways... Here's my code submission, My Ruby is a bit rusty

   input = ["cat", 1, "dog", 2, "wombat", 3]
   hash = Hash.new
   input.each_with_index {|item, index|
     if (index%2 == 0) hash[item] = input[index+1]
   }
   hash   #=> {"cat"=>1, "wombat"=>3, "dog"=>2}

Download the Apk file from net and copy it to platform-tools of your SDK folder, then in command prompt go to that directory an type:

adb install filename.apk

press enter it will install in few seconds

$(function() {
     var pgurl = window.location.href.substr(window.location.href.lastIndexOf("/")+1);
     $(".nav li").each(function(){
          if($('a',this).attr("href") == pgurl || $('a', this).attr("href") == '' )
          $(this).addClass("active");
     })
});

All previous answers are great , i just thought to give an insight on why a structure can't contain an instance of its own type (not a reference).

its very important to note that structures are 'value' types i.e they contain the actual value, so when you declare a structure the compiler has to decide how much memory to allocate to an instance of it, so it goes through all its members and adds up their memory to figure out the over all memory of the struct, but if the compiler found an instance of the same struct inside then this is a paradox (i.e in order to know how much memory struct A takes you have to decide how much memory struct A takes !).

But reference types are different, if a struct 'A' contains a 'reference' to an instance of its own type, although we don't know yet how much memory is allocated to it, we know how much memory is allocated to a memory address (i.e the reference).

HTH

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

Solution without fixing size on your margin

.content .right{
    overflow: auto; 
    background-color: red;
}

+1 for Merkuro, but if the size of the float changes your fixed margin will fail. If u use above CSS on the right div it will nicely change size with changing size on the left float. It is a bit more flexible like that. Check the fiddle here: http://jsfiddle.net/9ZHBK/144/

This solves the problem:

df['newcolumn'] = df.A * df.B

You could also do:

def fab(row):
  return row['A'] * row['B']

df['newcolumn'] = df.apply(fab, axis=1)

You can either do

SELECT name
FROM table2
WHERE name NOT IN
    (SELECT name 
     FROM table1)

or

SELECT name 
FROM table2 
WHERE NOT EXISTS 
    (SELECT * 
     FROM table1 
     WHERE table1.name = table2.name)

See this question for 3 techniques to accomplish this

Implementing IEnumerable means your class returns an IEnumerator object:

public class People : IEnumerable
{
    IEnumerator IEnumerable.GetEnumerator()
    {
        // return a PeopleEnumerator
    }
}

Implementing IEnumerator means your class returns the methods and properties for iteration:

public class PeopleEnumerator : IEnumerator
{
    public void Reset()...

    public bool MoveNext()...

    public object Current...
}

That's the difference anyway.

I installed the Krypton.Toolkit which added the tools to the Visual studio toolbox automatically. I then added the tools to the designer, which automatically added the dll to the projrect references, however the toolkit was marked as CopyLocal=false

I built an installer, using all dlls in the release build folder (of course the above dll wasn't there).

Setting copylocal=true, then rebuilding the installer, everything worked fine.

You can simply write

try
 {
    //Your Logic and code
 }
 catch (Exception ex)
 {
    //Error message in  alert box
    Response.Write("<script>alert('Error :" +ex.Message+"');</script>");
 }

it will work fine

As per the official documents, it's not anymore advisable to use matrix class since it will be removed in the future.

https://numpy.org/doc/stable/reference/generated/numpy.matrix.html

As other answers already state that you can achieve all the operations with NumPy arrays.

I realise this is a moot question to the OP, but I just brewed this, and I'm a tad proud of myself for thinking outside the box.

Download gawk for Windows at http://gnuwin32.sourceforge.net/packages/gawk.htm .... Then it's a one liner, without all that clunky DOS batch syntax, where it takes six FOR loops to split the strings (WTF? That's really really BAD MAD AND SAD! ... IMHO of course)

If you already know C, C++, Perl, or Ruby then picking-up AWK (which inherits from the former two, and contributes significantly to the latter two) is a piece of the proverbial CAKE!!!

The DOS Batch command:

echo %DATE% %TIME% && echo %DATE% %TIME% | gawk -F"[ /:.]" "{printf(""""%s%02d%02d-%02d%02d%02d\n"""", $4, $3, $2, $5, $6, $7);}"

Prints:

Tue 04/09/2012 10:40:38.25
20120904-104038

Now that's not quite the full story... I'm just going to be lazy and hard-code the rest of my log-file-name in the printf statement, because it's simple... But if anybody knows how to set a %NOW% variable to AWK's output (yeilding the guts of a "generic" now function) then I'm all ears.

EDIT:

A quick search on Stack Overflow filled in that last piece of the puzzle, Batch equivalent of Bash backticks.

So, these three lines of DOS batch:

echo %DATE% %TIME% | awk -F"[ /:.]" "{printf(""""%s%02d%02d-%02d%02d%02d\n"""", $4, $3, $2, $5, $6, $7);}" >%temp%\now.txt
set /p now=<%temp%\now.txt
echo %now%

Produce:

20120904-114434

So now I can include a datetime in the name of the log-file produced by my SQL Server installation (2005+) script thus:

sqlcmd -S .\SQLEXPRESS -d MyDb -e -i MyTSqlCommands.sql >MyTSqlCommands.sql.%now%.log

And I'm a happy camper again (except life was still SOOOOO much easier on Unix).

Generally you shouldn't rely on system properties to configure a webapp - they may be used to configure the container (e.g. Tomcat) but not an application running inside tomcat.

cliff.meyers has already mentioned the way you should rather use for your webapplication. That's the standard way, that also fits your question of being configurable through context.xml or server.xml means.

That said, should you really need system properties or other jvm options (like max memory settings) in tomcat, you should create a file named "bin/setenv.sh" or "bin/setenv.bat". These files do not exist in the standard archive that you download, but if they are present, the content is executed during startup (if you start tomcat via startup.sh/startup.bat). This is a nice way to separate your own settings from the standard tomcat settings and makes updates so much easier. No need to tweak startup.sh or catalina.sh.

(If you execute tomcat as windows servive, you usually use tomcat5w.exe, tomcat6w.exe etc. to configure the registry settings for the service.)

EDIT: Also, another possibility is to go for JNDI Resources.

It's not working because console.log() it's not in a "executable area" of the class "App".

A class is a structure composed by attributes and methods.

The only way to have your code executed is to place it inside a method that is going to be executed. For instance: constructor()

console.log('It works here')_x000D_
_x000D_
@Component({..)_x000D_
export class App {_x000D_
 s: string = "Hello2";_x000D_
            _x000D_
  constructor() {_x000D_
    console.log(this.s)            _x000D_
  }            _x000D_
}

Think of class like a plain javascript object.

Would it make sense to expect this to work?

class:  {_x000D_
  s: string,_x000D_
  console.log(s)_x000D_
 }

If you still unsure, try the typescript playground where you can see your typescript code generated into plain javascript.

Until I get a better option, this is the most "bootstrappy" answer I can work out:

JSFiddle: http://jsfiddle.net/TrueBlueAussie/6cbrjrt5/

I have switched to using LESS and including the Bootstrap Source NuGet package to ensure compatibility (by giving me access to the bootstrap variables.less file:

in _layout.cshtml master page

• Move footer outside the body-content container
• Use boostrap's navbar-fixed-bottom on the footer
• Drop the <hr/> before the footer (as now redundant)

Relevant page HTML:

<div class="container-fluid body-content">
    @RenderBody()
</div>
<footer class="navbar-fixed-bottom">
    <p>&copy; @DateTime.Now.Year - My ASP.NET Application</p>
</footer>

In Site.less

• Set HTML and BODY heights to 100%
• Set BODY overflow to hidden
• Set body-content div position to absolute
• Set body-content div top to @navbar-height instead of hard-wiring value
• Set body-content div bottom to 30px.
• Set body-content div left and right to 0
• Set body-content div overflow-y to auto

Site.less

html {
    height: 100%;

    body {
        height: 100%;
        overflow: hidden;

        .container-fluid.body-content {
            position: absolute;
            top: @navbar-height;
            bottom: 30px;
            right: 0;
            left: 0;
            overflow-y: auto;
        }
    }
}

The remaining problem is there seems to be no defining variable for the footer height in bootstrap. If someone call tell me if there is a magic 30px variable defined in Bootstrap I would appreciate it.

If you're open to changing the original string, you can simply replace the delimiter with \0. The original pointer will point to the first string and the pointer to the character after the delimiter will point to the second string. The good thing is you can use both pointers at the same time without allocating any new string buffers.

We have used both and we like Bootstrap for its simplicity and the pace at which it's being developed and enhanced. The problem with jQuery UI is that it's moving at a snail's pace. It's taking years to roll out common features like Menubar, Tree control and DataGrid which are in planning/development stage for ever. We waited waited waited and finally given up and used other libraries like ExtJS for our product http://dblite.com.

Bootstrap has come up with quite a comprehensive set of features in a very short period of time and I am sure it will outpace jQuery UI pretty soon.

So I see no point in using something that will eventually be outdated...

Not tested, but I think you can do the following:

dataGrid.Rows[index].Selected = true;

or you could do the following (but again: not tested):

dataGrid.SelectedRows.Clear();
foreach(DataGridViewRow row in dataGrid.Rows)
{
    if(YOUR CONDITION)
       row.Selected = true;
}

There are two ways to do this. The System.Diagnostics.StackTrace() will give you a stack trace for the current thread. If you have a reference to a Thread instance, you can get the stack trace for that via the overloaded version of StackTrace().

You may also want to check out Stack Overflow question How to get non-current thread's stacktrace?.

No need to do that mess.

Based on some of the great suggestions here already, I was able to put together the following lightweight, Interface-Builder-compatible subclass of UITextView, which:

• Includes configurable placeholder text, styled just like that of UITextField.
• Doesn't require any additional subviews or constraints.
• Doesn't require any delegation or other behaviour from the ViewController.
• Doesn't require any notifications.
• Keeps that placeholder text fully separated from any outside classes looking at the field's text property.

Any improvement suggestions are welcome, especially if there's any way to pull iOS's placeholder color programatically, rather than hard-coding it.

Swift v5:

import UIKit
@IBDesignable class TextViewWithPlaceholder: UITextView {
    
    override var text: String! { // Ensures that the placeholder text is never returned as the field's text
        get {
            if showingPlaceholder {
                return "" // When showing the placeholder, there's no real text to return
            } else { return super.text }
        }
        set { super.text = newValue }
    }
    @IBInspectable var placeholderText: String = ""
    @IBInspectable var placeholderTextColor: UIColor = UIColor(red: 0.78, green: 0.78, blue: 0.80, alpha: 1.0) // Standard iOS placeholder color (#C7C7CD). See https://stackoverflow.com/questions/31057746/whats-the-default-color-for-placeholder-text-in-uitextfield
    private var showingPlaceholder: Bool = true // Keeps track of whether the field is currently showing a placeholder
    
    override func didMoveToWindow() {
        super.didMoveToWindow()
        if text.isEmpty {
            showPlaceholderText() // Load up the placeholder text when first appearing, but not if coming back to a view where text was already entered
        }
    }
    
    override func becomeFirstResponder() -> Bool {
        // If the current text is the placeholder, remove it
        if showingPlaceholder {
            text = nil
            textColor = nil // Put the text back to the default, unmodified color
            showingPlaceholder = false
        }
        return super.becomeFirstResponder()
    }
    
    override func resignFirstResponder() -> Bool {
        // If there's no text, put the placeholder back
        if text.isEmpty {
            showPlaceholderText()
        }
        return super.resignFirstResponder()
    }
    
    private func showPlaceholderText() {
        showingPlaceholder = true
        textColor = placeholderTextColor
        text = placeholderText
    }
}

To add to @BrianBeech's answer, this is even more trimmed down in java 8:

jdbcTemplate.query("select string1,string2 from table where x=1", (ResultSet rs) -> {
    HashMap<String,String> results = new HashMap<>();
    while (rs.next()) {
        results.put(rs.getString("string1"), rs.getString("string2"));
    }
    return results;
});

Here is another modified version that will compare a lower substring match. This works in Oracle 11g.

DECLARE
  match_count INTEGER;
-- Type the owner of the tables you are looking at
  v_owner VARCHAR2(255) :='OWNER_NAME';

-- Type the data type you are look at (in CAPITAL)
-- VARCHAR2, NUMBER, etc.
  v_data_type VARCHAR2(255) :='VARCHAR2';

-- Type the string you are looking at
  v_search_string VARCHAR2(4000) :='%lower-search-sub-string%';

BEGIN
  FOR t IN (SELECT table_name, column_name FROM all_tab_cols where owner=v_owner and data_type = v_data_type) LOOP

    EXECUTE IMMEDIATE 
    'SELECT COUNT(*) FROM '||t.table_name||' WHERE lower('||t.column_name||') like :1'
    INTO match_count
    USING v_search_string;

    IF match_count > 0 THEN
      dbms_output.put_line( t.table_name ||' '||t.column_name||' '||match_count );
    END IF;

  END LOOP;
END;

I didn't see any Add-Type based examples. Here is one using the GetUserName directly from advapi32.dll.

$sig = @'

public static extern bool GetUserName(System.Text.StringBuilder sb, ref Int32 length);
'@

Add-Type -MemberDefinition $sig -Namespace Advapi32 -Name Util

    @WebFilter(urlPatterns="/*")
    public class XSSFilter implements Filter {

        private static final org.apache.log4j.Logger LOGGER = LogManager.getLogger(XSSFilter.class);

        @Override
        public void init(FilterConfig filterConfig) throws ServletException {
            LOGGER.info("Initiating XSSFilter... ");

        }

        @Override
        public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
                throws IOException, ServletException {
            HttpServletRequest req = (HttpServletRequest) request;
            HttpRequestWrapper requestWrapper = new HttpRequestWrapper(req);
            chain.doFilter(requestWrapper, response);
        }

        @Override
        public void destroy() {
            LOGGER.info("Destroying XSSFilter... ");
        }

    }

You need to implement Filter and need to be annotated with @WebFilter(urlPatterns="/*")

And in Application or Configuration class you need to add @ServletComponentScan By this it your filter will get registered.

json.loads will load a json string into a python dict, json.dumps will dump a python dict to a json string, for example:

>>> json_string = '{"favorited": false, "contributors": null}'
'{"favorited": false, "contributors": null}'
>>> value = json.loads(json_string)
{u'favorited': False, u'contributors': None}
>>> json_dump = json.dumps(value)
'{"favorited": false, "contributors": null}'

So that line is incorrect since you are trying to load a python dict, and json.loads is expecting a valid json string which should have <type 'str'>.

So if you are trying to load the json, you should change what you are loading to look like the json_string above, or you should be dumping it. This is just my best guess from the given information. What is it that you are trying to accomplish?

Also you don't need to specify the u before your strings, as @Cld mentioned in the comments.

None of these answers worked for me, when all I had was a list of directories. Then I stumbled upon the solution! You have to add -r to --files-from because -a will not be recursive in this scenario (who knew?!).

rsync -aruRP --files-from=directory.list . ../new/location

You can do the following:

JSONArray jsonArray = jsnobject.getJSONArray("locations");
    for (int i = 0; i < jsonArray.length(); i++) {
        JSONObject explrObject = jsonArray.getJSONObject(i);
}

Using ToString("HH:mm") certainly gives you what you want as a string.

If you want the current hour/minute as numbers, string manipulation isn't necessary; you can use the TimeOfDay property:

TimeSpan timeOfDay = fechaHora.TimeOfDay;
int hour = timeOfDay.Hours;
int minute = timeOfDay.Minutes;

Here's a library I forked from CodeMonkeysRU.

The reason I forked was because Google requires exponential backoff. I use a redis server to queue messages and resend after a set time.

I've also updated it to support iOS.

Agree with redsquare however it is worth mentioning that if you have a two word property like text-align you would do this:

$("#message").css({ width: '30px', height: '10px', 'text-align': 'center'});

The best source is probably Apple's official documentation. The specific variable you are looking for is CONFIGURATION.

It is very simple. For example : in you JS controller use this:

$scope.inputngmodel.$valid = false;

or

$scope.inputngmodel.$invalid = true;

or

$scope.formname.inputngmodel.$valid = false;

or

$scope.formname.inputngmodel.$invalid = true;

All works for me for different requirement. Hit up if this solve your problem.

Answer is pretty simple, I also faced the problem finally I got perfect solution. Create Debug Create Remote debug with following configuration Firstly run by debug. It gives you waitng for socket 5005 then run with remote debug

try:

.table-hover > tbody > tr.active:hover > th {
                background-color: #color;
            }

To read only the first row of the csv file use next() on the reader object.

with open('some.csv', newline='') as f:
  reader = csv.reader(f)
  row1 = next(reader)  # gets the first line
  # now do something here 
  # if first row is the header, then you can do one more next() to get the next row:
  # row2 = next(f)

or :

with open('some.csv', newline='') as f:
  reader = csv.reader(f)
  for row in reader:
    # do something here with `row`
    break

The simplest solution is to apply Python str function to the column you are trying to loop through.

If you are using pandas, this can be implemented as:

dataframe['column_name']=dataframe['column_name'].apply(str)

Maybe (from git commit man page):

git commit --no-verify

-n  
--no-verify

This option bypasses the pre-commit and commit-msg hooks. See also githooks(5).

As commented by Blaise, -n can have a different role for certain commands.
For instance, git push -n is actually a dry-run push.
Only git push --no-verify would skip the hook.

Note: Git 2.14.x/2.15 improves the --no-verify behavior:

See commit 680ee55 (14 Aug 2017) by Kevin Willford (``).
^{(Merged by Junio C Hamano -- gitster -- in commit c3e034f, 23 Aug 2017)}

commit: skip discarding the index if there is no pre-commit hook

"git commit" used to discard the index and re-read from the filesystem just in case the pre-commit hook has updated it in the middle; this has been optimized out when we know we do not run the pre-commit hook.

Davi Lima points out in the comments the git cherry-pick does not support --no-verify.
So if a cherry-pick triggers a pre-commit hook, you might, as in this blog post, have to comment/disable somehow that hook in order for your git cherry-pick to proceed.
The same process would be necessary in case of a git rebase --continue, after a merge conflict resolution.

In case one does not have sudo privilege, but still needs to install the library.

Download source for the software/library using:

apt-get source libaio

or

wget https://src.fedoraproject.org/lookaside/pkgs/libaio/libaio-0.3.110.tar.gz/2a35602e43778383e2f4907a4ca39ab8/libaio-0.3.110.tar.gz

unzip the library

Install with the following command to user-specific library:

make prefix=`pwd`/usr install #(Copy from INSTALL file of libaio-0.3.110)

or

make prefix=/path/to/your/lib/libaio install

Include libaio library into LD_LIBRARY_PATH for your app:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/your/lib/libaio/lib

Now, your app should be able to find libaio.so.1

1. Implement a slot in your QMainWindow where you will open your new Window,
2. Place a widget on your QMainWindow,
3. Connect a signal from this widget to a slot from the QMainWindow (for example: if the widget is a QPushButton connect the signal click() to the QMainWindow custom slot you have created).

Code example:

MainWindow.h

// ...
include "newwindow.h"
// ...
public slots:
   void openNewWindow();
// ...
private:
   NewWindow *mMyNewWindow;
// ...
}

MainWindow.cpp

// ...
   MainWindow::MainWindow()
   {
      // ...
      connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
      // ...
   }
// ...
void MainWindow::openNewWindow()
{
   mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
   mMyNewWindow->show();
   // ...
}

This is an example on how display a custom new window. There are a lot of ways to do this.

Try this. This should work:

<div data-role="page" id="page" style="background-image: url('#URL'); background-attachment: fixed; background-repeat: no-repeat; background-size: 100% 100%;"
    data-theme="a">

Edit: As said by Chips_100 you should use :

var sizes = document.theForm[field];

directly without using the test variable.

Old answer:

Shouldn't you eval like this ?

var sizes = eval(test);

I don't know how that works, but to me you're only copying a string.

From the Javadoc of Method.invoke()

Throws: InvocationTargetException - if the underlying method throws an exception.

This exception is thrown if the method called threw an exception.

In addition to the potential locking problems you might cause you will also find that your transaction logs begin to grow as they can not be truncated past the minimum LSN for an active transaction and if you are using snapshot isolation your version store in tempdb will grow for similar reasons.

You can use dbcc opentran to see details of the oldest open transaction.

I have found that the problem with IE is that it sniffs the return data and makes up its own mind about what content-type it thinks it has been sent. There are a number of side effect that this causes, such as always openning a saveAs dialog for text files because you are using compression of data trasnferes. The solution is (in php code)......

header('X-Content-Type-Options: nosniff');

Only CSS & bootstrap class

        <div class="col-md-4 input-group">
            <input class="form-control" type="text"/>
            <div class="input-group-btn">
                <label for="files" class="btn btn-default">browse</label>
                <input id="files" type="file" class="btn btn-default"  style="visibility:hidden;"/>
            </div>
        </div>

You are going to have to expose and endpoint (URL) in your system which will accept the POST request from the ajax call in jQuery.

Then, when processing that url from PHP, you would call your function and return the result in the appropriate format (JSON most likely, or XML if you prefer).

You can use the FileStream.Write(byte[] array, int offset, int count) method to write it out.

If your array name is "myArray" the code would be.

myStream.Write(myArray, 0, myArray.count);

basically i use this in one of our apps: we want to overlay a playicon over a frame of a video:

Image playbutton;
try
{
    playbutton = Image.FromFile(/*somekindofpath*/);
}
catch (Exception ex)
{
    return;
}

Image frame;
try
{
    frame = Image.FromFile(/*somekindofpath*/);
}
catch (Exception ex)
{
    return;
}

using (frame)
{
    using (var bitmap = new Bitmap(width, height))
    {
        using (var canvas = Graphics.FromImage(bitmap))
        {
            canvas.InterpolationMode = InterpolationMode.HighQualityBicubic;
            canvas.DrawImage(frame,
                             new Rectangle(0,
                                           0,
                                           width,
                                           height),
                             new Rectangle(0,
                                           0,
                                           frame.Width,
                                           frame.Height),
                             GraphicsUnit.Pixel);
            canvas.DrawImage(playbutton,
                             (bitmap.Width / 2) - (playbutton.Width / 2),
                             (bitmap.Height / 2) - (playbutton.Height / 2));
            canvas.Save();
        }
        try
        {
            bitmap.Save(/*somekindofpath*/,
                        System.Drawing.Imaging.ImageFormat.Jpeg);
        }
        catch (Exception ex) { }
    }
}

Table: Table is a preliminary storage for storing data and information in RDBMS. A table is a collection of related data entries and it consists of columns and rows.

View: A view is a virtual table whose contents are defined by a query. Unless indexed, a view does not exist as a stored set of data values in a database. Advantages over table are

• We can combine columns/rows from multiple table or another view and have a consolidated view.
• Views can be used as security mechanisms by letting users access data through the view, without granting the users permissions to directly access the underlying base tables of the view
• It acts as abstract layer to downstream systems, so any change in schema is not exposed and hence the downstream systems doesn't get affected.

you have to name your checkboxes accordingly:

<input type="checkbox" name="check_list[]" value="…" />

you can then access all checked checkboxes with

// loop over checked checkboxes
foreach($_POST['check_list'] as $checkbox) {
   // do something
}

ps. make sure to properly escape your output (htmlspecialchars())

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

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

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

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

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

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

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

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

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

%wheel ALL=(ALL) NOPASSWD: ALL

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

We use Akka in several projects at work, the most interesting of which is related to vehicle crash repair. Primarily in the UK but now expanding to the US, Asia, Australasia and Europe. We use actors to ensure that crash repair information is provided realtime to enable the safe and cost effective repair of vehicles.

The question with Akka is really more 'what can't you do with Akka'. Its ability to integrate with powerful frameworks, its powerful abstraction and all of the fault tolerance aspects make it a very comprehensive toolkit.

Here is another way you can get to the root of your website without hard coding the url:

var response = Request.CreateResponse(HttpStatusCode.Moved);
string fullyQualifiedUrl = Request.RequestUri.GetLeftPart(UriPartial.Authority);
response.Headers.Location = new Uri(fullyQualifiedUrl);

Note: Will only work if both your MVC website and WebApi are on the same URL

Use .splice to remove item from array. Using delete, indexes of the array will not be altered but the value of specific index will be undefined

The splice() method changes the content of an array by removing existing elements and/or adding new elements.

Syntax: array.splice(start, deleteCount[, item1[, item2[, ...]]])

var people = ["Bob", "Sally", "Jack"]_x000D_
var toRemove = 'Bob';_x000D_
var index = people.indexOf(toRemove);_x000D_
if (index > -1) { //Make sure item is present in the array, without if condition, -n indexes will be considered from the end of the array._x000D_
  people.splice(index, 1);_x000D_
}_x000D_
console.log(people);

Edit:

As pointed out by justin-grant, As a rule of thumb, Never mutate this.state directly, as calling setState() afterward may replace the mutation you made. Treat this.state as if it were immutable.

The alternative is, create copies of the objects in this.state and manipulate the copies, assigning them back using setState(). Array#map, Array#filter etc. could be used.

this.setState({people: this.state.people.filter(item => item !== e.target.value);});

The best solution we found was to team up with one of those intermediaries. Otherwise you will have to deal with a bunch of other requirements like PCI compliance. We use Verifone's IPCharge and it works quite well.

Borrowed from @Deena above, that function modification for labels is more versatile than you might have thought. For example, I had a ggplot where the denominator of counted variables was 140. I used her example thus:

scale_y_continuous(labels = function(x) paste0(round(x/140*100,1), "%"), breaks = seq(0, 140, 35))

This allowed me to get my percentages on the 140 denominator, and then break the scale at 25% increments rather than the weird numbers it defaulted to. The key here is that the scale breaks are still set by the original count, not by your percentages. Therefore the breaks must be from zero to the denominator value, with the third argument in "breaks" being the denominator divided by however many label breaks you want (e.g. 140 * 0.25 = 35).

I've had a lot of experience running a compiled regex 1000s of times versus compiling on-the-fly, and have not noticed any perceivable difference. Obviously, this is anecdotal, and certainly not a great argument against compiling, but I've found the difference to be negligible.

EDIT: After a quick glance at the actual Python 2.5 library code, I see that Python internally compiles AND CACHES regexes whenever you use them anyway (including calls to re.match()), so you're really only changing WHEN the regex gets compiled, and shouldn't be saving much time at all - only the time it takes to check the cache (a key lookup on an internal dict type).

From module re.py (comments are mine):

def match(pattern, string, flags=0):
    return _compile(pattern, flags).match(string)

def _compile(*key):

    # Does cache check at top of function
    cachekey = (type(key[0]),) + key
    p = _cache.get(cachekey)
    if p is not None: return p

    # ...
    # Does actual compilation on cache miss
    # ...

    # Caches compiled regex
    if len(_cache) >= _MAXCACHE:
        _cache.clear()
    _cache[cachekey] = p
    return p

I still often pre-compile regular expressions, but only to bind them to a nice, reusable name, not for any expected performance gain.

It depends, how big is the data set and what are your performance requirements?

If it's nothing gigantic use the most readable form, which for myself is any, because it's shorter and readable rather than an equation.

Wrote the below function that allows me to quickly check to see if an index exists; works just like OBJECT_ID.

CREATE FUNCTION INDEX_OBJECT_ID (
    @tableName VARCHAR(128),
    @indexName VARCHAR(128)
    )
RETURNS INT
AS
BEGIN
    DECLARE @objectId INT

    SELECT @objectId = i.object_id
    FROM sys.indexes i
    WHERE i.object_id = OBJECT_ID(@tableName)
    AND i.name = @indexName

    RETURN @objectId
END
GO

EDIT: This just returns the OBJECT_ID of the table, but it will be NULL if the index doesn't exist. I suppose you could set this to return index_id, but that isn't super useful.

I'm not sure of the details as you haven't posted the whole code, but:

• remember to override hashCode() as well
• the equals method should have Object, not People as its argument type. At the moment you are overloading, not overriding, the equals method, which probably isn't what you want, especially given that you check its type later.
• you can use instanceof to check it is a People object e.g. if (!(other instanceof People)) { result = false;}
• equals is used for all objects, but not primitives. I think you mean age is an int (primitive), in which case just use ==. Note that an Integer (with a capital 'I') is an Object which should be compared with equals.

See What issues should be considered when overriding equals and hashCode in Java? for more details.

If you're using GNU find,

find . -mtime 1 -exec cp -t ~/test/ {} +

This works as well as piping the output into xargs while avoiding the pitfalls of doing so (it handles embedded spaces and newlines without having to use find ... -print0 | xargs -0 ...).

If you example class is instantiated on the stack, the contents of uninitialized scalar members is random and undefined.

For a global instance, uninitialized scalar members will be zeroed.

For members which are themselves instances of classes, their default constructors will be called, so your string object will get initialized.

• int *ptr; //uninitialized pointer (or zeroed if global)
• string name; //constructor called, initialized with empty string
• string *pname; //uninitialized pointer (or zeroed if global)
• string &rname; //compilation error if you fail to initialize this
• const string &crname; //compilation error if you fail to initialize this
• int age; //scalar value, uninitialized and random (or zeroed if global)

Similarly, with dictionaries of arrays one can:

var dict1 = [String:[Int]]()
var dict2 = [String:[Int]]()
dict1["key"] = [1,2,3]
dict2["key"] = [4,5,6]
dict1["key"] = dict1["key"]! + dict2["key"]!
print(dict1["key"]!)

and you can iterate over dict1 and add dict2 if the "key" matches

You need to use regular expressions in your custom validator. For example, here's the code that allows only 9 digits in the input fields:

function ssnValidator(control: FormControl): {[key: string]: any} {
  const value: string = control.value || '';
  const valid = value.match(/^\d{9}$/);
  return valid ? null : {ssn: true};
}

Take a look at a sample app here:

https://github.com/Farata/angular2typescript/tree/master/Angular4/form-samples/src/app/reactive-validator

There is no difference, except that Pragma is only defined as applicable to the requests by the client, whereas Cache-Control may be used by both the requests of the clients and the replies of the servers.

So, as far as standards go, they can only be compared from the perspective of the client making a requests and the server receiving a request from the client. The http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.32 defines the scenario as follows:

HTTP/1.1 caches SHOULD treat "Pragma: no-cache" as if the client had sent "Cache-Control: no-cache". No new Pragma directives will be defined in HTTP.

  Note: because the meaning of "Pragma: no-cache as a response
  header field is not actually specified, it does not provide a
  reliable replacement for "Cache-Control: no-cache" in a response

The way I would read the above:

• if you're writing a client and need no-cache:

  • just use Pragma: no-cache in your requests, since you may not know if Cache-Control is supported by the server;
  • but in replies, to decide on whether to cache, check for Cache-Control

• if you're writing a server:

  • in parsing requests from the clients, check for Cache-Control; if not found, check for Pragma: no-cache, and execute the Cache-Control: no-cache logic;
  • in replies, provide Cache-Control.

Of course, reality might be different from what's written or implied in the RFC!

Update or insert without known primary key

If you already have a unique or primary key, the other answers with either INSERT INTO ... ON DUPLICATE KEY UPDATE ... or REPLACE INTO ... should work fine (note that replace into deletes if exists and then inserts - thus does not partially update existing values).

But if you have the values for some_column_id and some_type, the combination of which are known to be unique. And you want to update some_value if exists, or insert if not exists. And you want to do it in just one query (to avoid using a transaction). This might be a solution:

INSERT INTO my_table (id, some_column_id, some_type, some_value)
SELECT t.id, t.some_column_id, t.some_type, t.some_value
FROM (
    SELECT id, some_column_id, some_type, some_value
    FROM my_table
    WHERE some_column_id = ? AND some_type = ?
    UNION ALL
    SELECT s.id, s.some_column_id, s.some_type, s.some_value
    FROM (SELECT NULL AS id, ? AS some_column_id, ? AS some_type, ? AS some_value) AS s
) AS t
LIMIT 1
ON DUPLICATE KEY UPDATE
some_value = ?

Basically, the query executes this way (less complicated than it may look):

• Select an existing row via the WHERE clause match.
• Union that result with a potential new row (table s), where the column values are explicitly given (s.id is NULL, so it will generate a new auto-increment identifier).
• If an existing row is found, then the potential new row from table s is discarded (due to LIMIT 1 on table t), and it will always trigger an ON DUPLICATE KEY which will UPDATE the some_value column.
• If an existing row is not found, then the potential new row is inserted (as given by table s).

Note: Every table in a relational database should have at least a primary auto-increment id column. If you don't have this, add it, even when you don't need it at first sight. It is definitely needed for this "trick".

If you have downloaded these files locally then you can change following classes in bootstrap-social.css, just added border-radius: 50%;

.btn-social-icon.btn-lg{height:45px;width:45px;
   padding-left:0;padding-right:0; border-radius: 50%; }

And here is teh HTML

<a class="btn btn-social-icon btn-lg btn-twitter" >
   <i class="fa fa-twitter"></i>
</a>
<a class=" btn btn-social-icon btn-lg btn-facebook">
   <i class="fa fa-facebook sbg-facebook"></i>
</a>
<a class="btn btn-social-icon btn-lg btn-google-plus">
   <i class="fa fa-google-plus"></i>
</a>

It works smooth for me.

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

Good size is 33%

sed --expression='s/\r\n/\n/g'

Since the question mentions sed, this is the most straight forward way to use sed to achieve this. What the expression says is replace all carriage-return and line-feed with just line-feed only. That is what you need when you go from Windows to Unix. I verified it works.

pg_basebackup seems to be the better way of doing this now, especially for large databases.

You can copy a database from a server with the same or older major version. Or more precisely:

pg_basebackup works with servers of the same or an older major version, down to 9.1. However, WAL streaming mode (-X stream) only works with server version 9.3 and later, and tar format mode (--format=tar) of the current version only works with server version 9.5 or later.

For that you need on the source server:

1. listen_addresses = '*' to be able to connect from the target server. Make sure port 5432 is open for that matter.
2. At least 1 available replication connection: max_wal_senders = 1 (-X fetch), 2 for -X stream (the default in case of PostgreSQL 12), or more.
3. wal_level = replica or higher to be able to set max_wal_senders > 0.
4. host replication postgres DST_IP/32 trust in pg_hba.conf. This grants access to the pg cluster to anyone from the DST_IP machine. You might want to resort to a more secure option.

Changes 1, 2, 3 require server restart, change 4 requires reload.

On the target server:

# systemctl stop postgresql@VERSION-NAME
postgres$ pg_basebackup -h SRC_IP -U postgres -D VERSION/NAME --progress
# systemctl start postgresql@VERSION-NAME

Default methods in Java Interface are to be used more for providing dummy implementation of a function thus saving any implementing class of that interface from the pain of declaring all the abstract methods even if they want to deal with only one. Default methods in interface are thus in a way more a replacement for the concept of adapter classes.

The methods in abstract class are however supposed to give a meaningful implementation which any child class should override only if needed to override a common functionality.

Your helpful comments led me to the following solution:

class Word_Parser:
    """docstring for Word_Parser"""
    def __init__(self, sentences):
        self.sentences = sentences

    def parser(self):
        self.word_list = self.sentences.split()
        word_list = []
        word_list = self.word_list
        return word_list

    def sort_word_list(self):
        self.sorted_word_list = sorted(self.sentences.split())
        sorted_word_list = self.sorted_word_list
        return sorted_word_list

    def get_num_words(self):
        self.num_words = len(self.word_list)
        num_words = self.num_words
        return num_words

test = Word_Parser("mary had a little lamb")
test.parser()
test.sort_word_list()
test.get_num_words()
print test.word_list
print test.sorted_word_list
print test.num_words

and returns: ['mary', 'had', 'a', 'little', 'lamb'] ['a', 'had', 'lamb', 'little', 'mary'] 5

Thank you all.

Try this (ES5)

console.log($("#" +  d));

ES6

console.log($(`#${d}`));

You need to attach the Form1_Load handler to the Load event:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Windows.Forms.DataVisualization.Charting;
using System.Diagnostics;

namespace WindowsFormsApplication6
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            Load += Form1_Load;
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Random rnd = new Random();
            Chart mych = new Chart();
            mych.Height = 100;
            mych.Width = 100;
            mych.BackColor = SystemColors.Highlight;
            mych.Series.Add("duck");

            mych.Series["duck"].SetDefault(true);
            mych.Series["duck"].Enabled = true;
            mych.Visible = true;

            for (int q = 0; q < 10; q++)
            {
                int first = rnd.Next(0, 10);
                int second = rnd.Next(0, 10);
                mych.Series["duck"].Points.AddXY(first, second);
                Debug.WriteLine(first + "  " + second);
            }

            Controls.Add(mych);
        }
    }
}

As suggested by @Brandan, here's what I needed to do to get around

error: Your local changes to the following files would be overwritten by merge:
       file.txt
Please, commit your changes or stash them before you can merge.
Aborting

Follow this process:

git status  # local changes to `file`
git stash list  # further changes to `file` we want to merge
git commit -m "WIP" file
git stash pop
git commit -m "WIP2" file
git rebase -i HEAD^^  # I always use interactive rebase -- I'm sure you could do this in a single command with the simplicity of this process -- basically squash HEAD into HEAD^
# mark the second commit to squash into the first using your EDITOR
git reset HEAD^

And you'll be left with fully merged local changes to file, ready to do further work/cleanup or make a single good commit. Or, if you know the merged contents of file will be correct, you could write a fitting message and skip git reset HEAD^.

My url is like this http://www.default-search.net/?sid=503 . I want to get 503 . I wrote the following code .

var baseUrl = (window.location).href; // You can also use document.URL
var koopId = baseUrl.substring(baseUrl.lastIndexOf('=') + 1);
alert(koopId)//503

If you use

var v = window.location.pathname;
console.log(v)

You will get only "/";

To get dpi:

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);

// will either be DENSITY_LOW, DENSITY_MEDIUM or DENSITY_HIGH
int dpiClassification = dm.densityDpi;

// these will return the actual dpi horizontally and vertically
float xDpi = dm.xdpi;
float yDpi = dm.ydpi;

The key here is to unlist the row first.

colnames(DF) <- as.character(unlist(DF[1,]))
DF = DF[-1, ]

For even newer version of Node.js (v8.1.4), the events and calls are similar or identical to older versions, but it's encouraged to use the standard newer language features. Examples:

For buffered, non-stream formatted output (you get it all at once), use child_process.exec:

const { exec } = require('child_process');
exec('cat *.js bad_file | wc -l', (err, stdout, stderr) => {
  if (err) {
    // node couldn't execute the command
    return;
  }

  // the *entire* stdout and stderr (buffered)
  console.log(`stdout: ${stdout}`);
  console.log(`stderr: ${stderr}`);
});

You can also use it with Promises:

const util = require('util');
const exec = util.promisify(require('child_process').exec);

async function ls() {
  const { stdout, stderr } = await exec('ls');
  console.log('stdout:', stdout);
  console.log('stderr:', stderr);
}
ls();

If you wish to receive the data gradually in chunks (output as a stream), use child_process.spawn:

const { spawn } = require('child_process');
const child = spawn('ls', ['-lh', '/usr']);

// use child.stdout.setEncoding('utf8'); if you want text chunks
child.stdout.on('data', (chunk) => {
  // data from standard output is here as buffers
});

// since these are streams, you can pipe them elsewhere
child.stderr.pipe(dest);

child.on('close', (code) => {
  console.log(`child process exited with code ${code}`);
});

Both of these functions have a synchronous counterpart. An example for child_process.execSync:

const { execSync } = require('child_process');
// stderr is sent to stderr of parent process
// you can set options.stdio if you want it to go elsewhere
let stdout = execSync('ls');

As well as child_process.spawnSync:

const { spawnSync} = require('child_process');
const child = spawnSync('ls', ['-lh', '/usr']);

console.log('error', child.error);
console.log('stdout ', child.stdout);
console.log('stderr ', child.stderr);

Note: The following code is still functional, but is primarily targeted at users of ES5 and before.

The module for spawning child processes with Node.js is well documented in the documentation (v5.0.0). To execute a command and fetch its complete output as a buffer, use child_process.exec:

var exec = require('child_process').exec;
var cmd = 'prince -v builds/pdf/book.html -o builds/pdf/book.pdf';

exec(cmd, function(error, stdout, stderr) {
  // command output is in stdout
});

If you need to use handle process I/O with streams, such as when you are expecting large amounts of output, use child_process.spawn:

var spawn = require('child_process').spawn;
var child = spawn('prince', [
  '-v', 'builds/pdf/book.html',
  '-o', 'builds/pdf/book.pdf'
]);

child.stdout.on('data', function(chunk) {
  // output will be here in chunks
});

// or if you want to send output elsewhere
child.stdout.pipe(dest);

If you are executing a file rather than a command, you might want to use child_process.execFile, which parameters which are almost identical to spawn, but has a fourth callback parameter like exec for retrieving output buffers. That might look a bit like this:

var execFile = require('child_process').execFile;
execFile(file, args, options, function(error, stdout, stderr) {
  // command output is in stdout
});

As of v0.11.12, Node now supports synchronous spawn and exec. All of the methods described above are asynchronous, and have a synchronous counterpart. Documentation for them can be found here. While they are useful for scripting, do note that unlike the methods used to spawn child processes asynchronously, the synchronous methods do not return an instance of ChildProcess.

If you've edited /etc/apache2/httpd.conf with the ServerName localhost you may be editing the wrong file. All answers I found were pointing towards that standard httpd.conf. After some foraging, I found a good answer here.

To locate the right httpd.conf file use

apachectl -t -D DUMP_INCLUDES

I found mine was actually /usr/local/etc/httpd/httpd.conf.

Use your preferred editor to comment out the line (i.e. remove the # before) starting with ServerName, and replace the domain name for the appropriate one – local environments should work with

ServerName localhost

I hope this helps more people who may be stuck.

This will work:

#!/usr/bin/expect -f

spawn scp -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no file1 file2 file3 user@host:/path/
expect "password:"
send "xyz123\r"
expect "*\r"
expect "\r"
interact

It is interesting to note that the map with default 0 value, intentionally designed for this case demonstrates the worst performance (and not as concise as groupBy)

It is curious that most concise groupBy is faster than even mutable map!

I think you may also use the command line :

git add -p

This allows you to review all your uncommited files, one by one and choose if you want to commit them or not.

Then you have some options that will come up for each modification: I use the "y" for "yes I want to add this file" and the "n" for "no, I will commit this one later".

Stage this hunk [y,n,q,a,d,K,g,/,e,?]?

As for the other options which are ( q,a,d,K,g,/,e,? ), I'm not sure what they do, but I guess the "?" might help you out if you need to go deeper into details.

The great thing about this is that you can then push your work, and create a new branch after and all the uncommited work will follow you on that new branch. Very useful if you have coded many different things and that you actually want to reorganise your work on github before pushing it.

Hope this helps, I have not seen it said previously (if it was mentionned, my bad)

Convert one of them to a double first. This form works in many languages:

 real_result = (int_numerator + 0.0) / int_denominator

There is no trigger to perform code when the app is deleted from the device. Access to the keychain is dependant on the provisioning profile that is used to sign the application. Therefore no other applications would be able to access this information in the keychain.

It does not help with you aim to remove the password in the keychain when the user deletes application from the device but it should give you some comfort that the password is not accessible (only from a re-install of the original application).

I have written a node module that provides a wrapper around setInterval using moment durations providing a declarative interface:

npm install every-moment

var every = require('every-moment');

var timer = every(5, 'seconds', function() {
    console.log(this.duration);
});

every(2, 'weeks', function() {
    console.log(this.duration);
    timer.stop();
    this.set(1, 'week');
    this.start();
});

https://www.npmjs.com/package/every-moment

https://github.com/raygerrard/every-moment

This is how I do it:

using System.IO;
using System.Security.Cryptography;

public string checkMD5(string filename)
{
    using (var md5 = MD5.Create())
    {
        using (var stream = File.OpenRead(filename))
        {
            return Encoding.Default.GetString(md5.ComputeHash(stream));
        }
    }
}

Yes you can do.

Syntax for CAST:

CAST ( expression AS data_type [ ( length ) ] )

For example:

CAST(MyColumn AS Varchar(10))

CAST in SELECT Statement:

Select CAST(MyColumn AS Varchar(10)) AS MyColumn
FROM MyTable

See for more information CAST and CONVERT (Transact-SQL)

You can do this:-

$('#about-link').addClass('current');
$('#menu li a').on('click', function(e){
    e.preventDefault();
    $('#menu li a.current').removeClass('current');
    $(this).addClass('current');
});

Demo: Fiddle

I would suggest Jetbrain's IDE: DataGrip https://www.jetbrains.com/datagrip/

If you editing info.plist directly, below should help you, don't key in "YES" as string below:

<key>UIFileSharingEnabled</key>
<string>YES</string>

You should use this:

<key>UIFileSharingEnabled</key>
<true/>

I solved this with selector. I do not initialize the datetime picker on inputs which are readonly.

$('[type=datetime]:not([readonly])').datetimepicker();

If you have F# (which will be in the next version of .NET), you can use

Seq.iter doSomething myIEnumerable

You can use String.valueOf() for float, double, int, boolean etc.

double d = 0;
float f = 0;
int i = 0;
short i1 = 0;
char c = 0;
boolean bool = false;
char[] chars = {};
Object obj = new Object();


String.valueOf(d);
String.valueOf(i);
String.valueOf(i1);
String.valueOf(f);
String.valueOf(c);
String.valueOf(chars);
String.valueOf(bool);
String.valueOf(obj);

Use a collection of some sort - this will make the code more readable and hide away all those constants. A simple way would be with a list:

// Declared with constants
private static List<Integer> myConstants = new ArrayList<Integer>(){{
    add(12);
    add(16);
    add(19);
}};

// Wherever you are checking for presence of the constant
if(myConstants.contains(x)){
    // ETC
}

As Bohemian points out the list of constants can be static so it's accessible in more than one place.

For anyone interested, the list in my example is using double brace initialization. Since I ran into it recently I've found it nice for writing quick & dirty list initializations.

Try using the os module.

import os

os.environ['DEBUSSY'] = '1'
os.environ['FSDB'] = '1'

# Open child processes via os.system(), popen() or fork() and execv()

someVariable = int(os.environ['DEBUSSY'])

See the Python docs on os.environ. Also, for spawning child processes, see Python's subprocess docs.

I loved @Slai's answer. I only had to make very minor modifications into the one-liners I was looking for. I thought I'd share what I ended up with in case it helps anyone else stumbling onto this page like I did:

DECLARE @Source VARCHAR(50) = '12345'
DECLARE @Encoded VARCHAR(500) = CONVERT(VARCHAR(500), (SELECT CONVERT(VARBINARY, @Source) FOR XML PATH(''), BINARY BASE64))
DECLARE @Decoded VARCHAR(500) = CONVERT(VARCHAR(500), CONVERT(XML, @Encoded).value('.','varbinary(max)'))
SELECT @Source AS [Source], @Encoded AS [Encoded], @Decoded AS [Decoded]

>>> dict(a=2,b=4)
{'a': 2, 'b': 4}

Will add the value in the python dictionary.

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

The height of list view items are adjusted based on its contents. In first image, no content. so height is very minimum. In second image, height is increased based on the size of the text. Because, you specified android:layout_height="wrap_content".

Local package is a annoying problem in go.

For some projects in our company we decide not use sub packages at all.

• $ glide install
• $ go get
• $ go install

All work.

For some projects we use sub packages, and import local packages with full path:

import "xxxx.gitlab.xx/xxgroup/xxproject/xxsubpackage

But if we fork this project, then the subpackages still refer the original one.

When you use background-size: cover the background image will automatically be stretched to cover the entire container. Aspect ratio is maintained however, so you will always lose part of the image, unless the aspect ratio of the image and the element it is applied to are identical.

I see two ways you could solve this:

• Do not maintain the aspect ratio of the image by setting background-size: 100% 100% This will also make the image cover the entire container, but the ratio will not be maintained. Disadvantage is that this distorts your image, and therefore may look very weird, depending on the image. With the image you are using in the fiddle, I think you could get away with it though.

• You could also calculate and set the height of the element with javascript, based on its width, so it gets the same ratio as the image. This calculation would have to be done on load and on resize. It should be easy enough with a few lines of code (feel free to ask if you want an example). Disadvantage of this method is that your width may become very small (on mobile devices), and therfore the calculated height also, which may cause the content of the container to overflow. This could be solved by changing the size of the content as well or something, but it adds some complexity to the solution/

You can use a trick to use scopes as you wish, just declare enum in such way:

struct Days 
{
   enum type
   {
      Saturday,Sunday,Tuesday,Wednesday,Thursday,Friday
   };
};

Days::type day = Days::Saturday;
if (day == Days::Saturday)

The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard. .jpeg and .jpg files are identical. JPEG images are identified with 6 different standard file name extensions:

• .jpg
• .jpeg

The jpg was used in Microsoft Operating Systems when they only supported 3 chars-extensions.

The JPEG File Interchange Format (JFIF - last three extensions in my list) is an image file format standard for exchanging JPEG encoded files compliant with the JPEG Interchange Format (JIF) standard, solving some of JIF's limitations in regard. Image data in JFIF files is compressed using the techniques in the JPEG standard, hence JFIF is sometimes referred to as "JPEG/JFIF".

The core problem is what you define line and whether end-on-line character sequence is part of the line or not. UNIX-based editors (such as VIM) or tools (such as Git) use EOL character sequence as line terminator, therefore it's a part of the line. It's similar to use of semicolon (;) in C and Pascal. In C semicolon terminates statements, in Pascal it separates them.

Just add this namespace,

using System.Linq;

The following code uses the definition of NAN (all exponent bits set, at least one fractional bit set) and assumes that sizeof(int) = sizeof(float) = 4. You can look up NAN in Wikipedia for the details.

bool IsNan( float value ) { return ((*(UINT*)&value) & 0x7fffffff) > 0x7f800000; }

You must write

<img src="theSource" style="width:30px;height:30px;" />

Inline styling will always take precedence over CSS styling. The width and height attributes are being overridden by your stylesheet, so you need to switch to this format.

I believe that if you already have a package it installed, pip will not overwrite it with another version. Use -I to ignore previous versions.

This works for me ...

public class ShadowImage extends Drawable {

Bitmap bm;

@Override
public void draw(Canvas canvas) {

    Paint mShadow = new Paint();
    Rect rect = new Rect(0,0,bm.getWidth(), bm.getHeight());

    mShadow.setAntiAlias(true);
    mShadow.setShadowLayer(5.5f, 4.0f, 4.0f, Color.BLACK);

    canvas.drawRect(rect, mShadow);
    canvas.drawBitmap(bm, 0.0f, 0.0f, null);

}

public ShadowImage(Bitmap bitmap) {
    super();
    this.bm = bitmap;
} ... }

Trying http://0.0.0.0:3000/routes on a Rails 5 API app (i.e.: JSON-only oriented) will (as of Rails beta 3) return

{"status":404,"error":"Not Found","exception":"#> 
<ActionController::RoutingError:...

However, http://0.0.0.0:3000/rails/info/routes will render a nice, simple HTML page with routes.

If you remove the href attribute the anchor will be not focusable and it will look like simple text, but it will still be clickable.

You can use dojox.dtl of DojoToolkit.org. Note that dojo 1.7 can well run on NodeJS and perform as a server side library. If you're interested, I can give you a simple example.

Use data type 'MultilineText':

[DataType(DataType.MultilineText)]
public string Text { get; set; }

See ASP.NET MVC3 - textarea with @Html.EditorFor

If you want the text value of a QString object you can use the __str__ property, like this:

>>> a = QtCore.QString("Happy Happy, Joy Joy!")
>>> a
PyQt4.QtCore.QString(u'Happy Happy, Joy Joy!')
>>> a.__str__()
u'Happy Happy, Joy Joy!'

Hope that helps.

I got the following error using Docker 19.03.8 on CentOS 7:

COPY failed: stat /var/lib/docker/tmp/docker-builderXXXXXXX/abc.txt: no such file or directory

The solution for me was to build from Docker file with docker build . instead of docker build - < Dockerfile.

If you start execution with gc logging turned on you get the info on file. Otherwise 'jmap -heap ' will give you what you want. See the jmap doc page for more.

Please note that jmap should not be used in a production environment unless absolutely needed as the tool halts the application to be able to determine actual heap usage. Usually this is not desired in a production environment.

Input: this is what it is this is what it can be

Output:

[this, is, what, it, is, this, is, what, it, can, be]

{can=1, what=2, be=1, this=2, is=3, it=2}

[1, 2, 1, 2, 3, 2]

[can, what, be, this, is, it]

quite late but it's the first hit i found from google

Instead of using the current directory or getting the assembly, just use the Application.ExecutablePath property:

//using System.IO;  
string applicationDirectory = Path.GetDirectoryName(Application.ExecutablePath);
string myFile = Path.Combine(applicationDirectory, "Sample.html");
webMain.Url = new Uri("file:///" + myFile);

All the timers have the equivalent of Start() and Stop() methods, except System.Threading.Timer.

So an extension method such as...

public static void Reset(this Timer timer)
{
  timer.Stop();
  timer.Start();
}

...is one way to go about it.

java.lang.Integer is not a super class of BigInteger. Both BigInteger and Integer do inherit from java.lang.Number, so you could cast to a java.lang.Number.

See the java docs http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Number.html

If I understand correctly, what you want to do, in pseudo-code is the following:

for (Tweet tweet : tweets) {
    if (!db.containsTweet(tweet.getId())) {
        db.insertTweet(tweet.getText(), tweet.getId());
    }
}

I assume your db class actually uses an sqlite database as a backend? What you could do is implement containsTweet directly and just query the database each time, but that seems less than perfect. The easiest solution if we go by your base code is to just keep a Set around that indexes the tweets. Since I can't be sure what the equals() method of Tweet looks like, I'll just store the identifiers in there. Then you get:

Set<Integer> tweetIds = new HashSet<Integer>(); // or long, whatever
for (Tweet tweet : tweets) {
    if (!tweetIds.contains(tweet.getId())) {
        db.insertTweet(tweet.getText(), tweet.getId());
        tweetIds.add(tweet.getId());
    }
}

It would probably be better to save a tiny bit of this work, by sorting the list of tweets to begin with and then just filtering out duplicate tweets. You could use:

// if tweets is a List
Collections.sort(tweets, new Comparator() {
    public int compare (Object t1, Object t2) {
        // might be the wrong way around
        return ((Tweet)t1).getId() - ((Tweet)t2).getId();
    }
}

Then process it

Integer oldId;
for (Tweet tweet : tweets) {
    if (oldId == null || oldId != tweet.getId()) {
        db.insertTweet(tweet.getText(), tweet.getId());
    }
    oldId = tweet.getId();
}

Yes, you could do this using a second for-loop, but you'll run into performance problems much more quickly than with this approach (although what we're doing here is trading time for memory performance, of course).

Importing jquery.easing cdn worked for me.

Recently I started using the Mac Pc for android development. When I go to

Android Studio => File => Other setting => Preference for New Projects..

I was not able to find plugin option in the setting page.

Later while clicking option on the toolbar, I clicked on "SDK Manager" it prompted the Settings where the Plugin option was visible and I was able to add the plugins from here.

After this, it opens the following setting

You can write like this:

img{
    width:100%;
    max-width:600px;
}

Check this http://jsfiddle.net/ErNeT/

Can be used as a shorthand in equality check.

So this code

if(ob != null && this.getClass() == ob.getClass) {
}

can be written as

if(ob instanceOf ClassA) {
}
