You should not use space character while naming database objects. Even though it's possible by using double quotes(quoted identifiers), CREATE TABLE "chartered flight" ...
, it's not recommended. Take a closer look here
My sphinx.conf
source post_source
{
type = mysql
sql_host = localhost
sql_user = ***
sql_pass = ***
sql_db = ***
sql_port = 3306
sql_query_pre = SET NAMES utf8
# query before fetching rows to index
sql_query = SELECT *, id AS pid, CRC32(safetag) as safetag_crc32 FROM hb_posts
sql_attr_uint = pid
# pid (as 'sql_attr_uint') is necessary for sphinx
# this field must be unique
# that is why I like sphinx
# you can store custom string fields into indexes (memory) as well
sql_field_string = title
sql_field_string = slug
sql_field_string = content
sql_field_string = tags
sql_attr_uint = category
# integer fields must be defined as sql_attr_uint
sql_attr_timestamp = date
# timestamp fields must be defined as sql_attr_timestamp
sql_query_info_pre = SET NAMES utf8
# if you need unicode support for sql_field_string, you need to patch the source
# this param. is not supported natively
sql_query_info = SELECT * FROM my_posts WHERE id = $id
}
index posts
{
source = post_source
# source above
path = /var/data/posts
# index location
charset_type = utf-8
}
Test script:
<?php
require "sphinxapi.php";
$safetag = $_GET["my_post_slug"];
// $safetag = preg_replace("/[^a-z0-9\-_]/i", "", $safetag);
$conf = getMyConf();
$cl = New SphinxClient();
$cl->SetServer($conf["server"], $conf["port"]);
$cl->SetConnectTimeout($conf["timeout"]);
$cl->setMaxQueryTime($conf["max"]);
# set search params
$cl->SetMatchMode(SPH_MATCH_FULLSCAN);
$cl->SetArrayResult(TRUE);
$cl->setLimits(0, 1, 1);
# looking for the post (not searching a keyword)
$cl->SetFilter("safetag_crc32", array(crc32($safetag)));
# fetch results
$post = $cl->Query(null, "post_1");
echo "<pre>";
var_dump($post);
echo "</pre>";
exit("done");
?>
Sample result:
[array] =>
"id" => 123,
"title" => "My post title.",
"content" => "My <p>post</p> content.",
...
[ and other fields ]
Sphinx query time:
0.001 sec.
Sphinx query time (1k concurrent):
=> 0.346 sec. (average)
=> 0.340 sec. (average of last 10 query)
MySQL query time:
"SELECT * FROM hb_posts WHERE id = 123;"
=> 0.001 sec.
MySQL query time (1k concurrent):
"SELECT * FROM my_posts WHERE id = 123;"
=> 1.612 sec. (average)
=> 1.920 sec. (average of last 10 query)
Had a similar problem with the GitHub because I was using HTTPS protocol. To check what protocol you're using just run
git config -l
and look at the line starting with remote.origin.url
. To switch your protocol
git config remote.origin.url [email protected]:your_username/your_project.git
This is an old post but I was looking for an answer and I found this: https://gifs.com. Just upload the video, then it creates a gif we can add easily in a github markdown. I tried it, the quality of the gif is a good one.
In Java or C#, an object cannot change its type once it has been instantiated.
So, if your object need to appear as a different object or behave differently depending on an object state or conditions, then use Composition: Refer to State and Strategy Design Patterns.
If the object need to be of the same type, then use Inheritance or implement interfaces.
I would like to mention that there's exception (not only) for 404 by default provided by Spring. See Spring documentation for details. So if you do not need your own exception you can simply do this:
@RequestMapping(value = "/**", method = RequestMethod.GET)
public ModelAndView show() throws NoSuchRequestHandlingMethodException {
if(something == null)
throw new NoSuchRequestHandlingMethodException("show", YourClass.class);
...
}
You're right: String is a subset of Object. Since String is more "precise" than Object, you should cast it to use it as an argument for System.out.println().
No.
You get charged for:
So... if you stop the EC2 instance you will only have to pay for the storage of the image on S3 (assuming you store an image ofcourse) and any IP addresses you've reserved.

When you print it with this print 'I\nwould\nexpect\nmultiple\nlines'
you would get:
I
would
expect
multiple
lines
The \n
is a new line character specially used for marking END-OF-TEXT. It signifies the end of the line or text. This characteristics is shared by many languages like C, C++ etc.
Try this
sudo -u hdfs hdfs dfsadmin -safemode leave
check status of safemode
sudo -u hdfs hdfs dfsadmin -safemode get
If it is still in safemode ,then one of the reason would be not enough space in your node, you can check your node disk usage using :
df -h
if root partition is full, delete files or add space in your root partition and retry first step.
For a popular alternative to colors that doesn't mess with the built-in methods of the String object, I recommend checking out cli-color.
Includes both colors and chainable styles such as bold, italic, and underline.

Seeing your loop for sending emails and the error which you provided there is only solution.
Declare the mail object out of the loop and assign fromaddress
out of the loop which you are using for sending mails. The fromaddress
field is getting assigned again and again in the loop that is your problem.
I recommend Navicat strongly. What I found particularly excellent are it's import functions - you can import almost any data format (Access, Excel, DBF, Lotus ...), define a mapping between the source and destination which can be saved and is repeatable (I even keep my mappings under version control).
I have tried SQLMaestro and found it buggy (particularly for data import); PGAdmin is limited.
Here is the code that worked for me!
Assuming that you have a valid session going,
//Get the current users id
$uid = $facebook->getUser();
//create the url
$profile_pic = "http://graph.facebook.com/".$uid."/picture";
//echo the image out
echo "<img src=\"" . $profile_pic . "\" />";
Thanx goes to Raine, you da man!
This works for me:
yarn add --dev tsconfig-paths
ts-node -r tsconfig-paths/register <your-index-file>.ts
This loads all paths in tsconfig.json. A sample tsconfig.json:
{
"compilerOptions": {
{…}
"baseUrl": "./src",
"paths": {
"assets/*": [ "assets/*" ],
"styles/*": [ "styles/*" ]
}
},
}
Make sure you have both baseUrl and paths for this to work
And then you can import like :
import {AlarmIcon} from 'assets/icons'
Cut has a --complement flag that makes it easy (and fast) to delete columns. The resulting syntax is analogous with what you want to do -- making the solution easier to read/understand. Complement also works for the case where you would like to delete non-contiguous columns.
$ foo='1 2 3 %s 5 6 7'
$ echo "$foo" | cut --complement -d' ' -f1-3
%s 5 6 7

Use ...from table(... :
create or replace type numbertype
as object
(nr number(20,10) )
/
create or replace type number_table
as table of numbertype
/
create or replace procedure tableselect
( p_numbers in number_table
, p_ref_result out sys_refcursor)
is
begin
open p_ref_result for
select *
from employees , (select /*+ cardinality(tab 10) */ tab.nr from table(p_numbers) tab) tbnrs
where id = tbnrs.nr;
end;
/
This is one of the rare cases where you need a hint, else Oracle will not use the index on column id. One of the advantages of this approach is that Oracle doesn't need to hard parse the query again and again. Using a temporary table is most of the times slower.
edit 1 simplified the procedure (thanks to jimmyorr) + example
create or replace procedure tableselect
( p_numbers in number_table
, p_ref_result out sys_refcursor)
is
begin
open p_ref_result for
select /*+ cardinality(tab 10) */ emp.*
from employees emp
, table(p_numbers) tab
where tab.nr = id;
end;
/
Example:
set serveroutput on
create table employees ( id number(10),name varchar2(100));
insert into employees values (3,'Raymond');
insert into employees values (4,'Hans');
commit;
declare
l_number number_table := number_table();
l_sys_refcursor sys_refcursor;
l_employee employees%rowtype;
begin
l_number.extend;
l_number(1) := numbertype(3);
l_number.extend;
l_number(2) := numbertype(4);
tableselect(l_number, l_sys_refcursor);
loop
fetch l_sys_refcursor into l_employee;
exit when l_sys_refcursor%notfound;
dbms_output.put_line(l_employee.name);
end loop;
close l_sys_refcursor;
end;
/
This will output:

This might fix your issue.
Your getElementById
is looking for an element with id "myclass", but in your html the id of the DIV is showhide
. Change to:
<script>
function changeclass() {
var NAME = document.getElementById("showhide")
NAME.className="mynewclass"
}
</script>
Unless you are trying to target a different element with the id "myclass", then you need to make sure such an element exists.
They are signals that application developers use. The kernel shouldn't ever send these to a process. You can send them using kill(2)
or using the utility kill(1)
.
If you intend to use signals for synchronization you might want to check real-time signals (there's more of them, they are queued, their delivery order is guaranteed etc).
Your question contains the string literal "\b[A-Z]{2,}\b"
,
but that \b
will mean backspace, because there is no r-modifier.
Try: r"\b[A-Z]{2,}\b"
.
There are two types of progress bars called determinate progress bar (fixed duration) and indeterminate progress bar (unknown duration).
Drawables for both of types of progress bar can be customized by defining drawable as xml resource. You can find more information about progress bar styles and customization at http://www.zoftino.com/android-progressbar-and-custom-progressbar-examples.
Customizing fixed or horizontal progress bar :
Below xml is a drawable resource for horizontal progress bar customization.
<?xml version="1.0" encoding="utf-8"?>

<item android:id="@android:id/background"
android:gravity="center_vertical|fill_horizontal">

android:tint="?attr/colorControlNormal">
<corners android:radius="8dp"/>
<size android:height="20dp" />
<solid android:color="#90caf9" />
</shape>
</item>
<item android:id="@android:id/progress"

Add the following to the top of your file # coding=utf-8
If you go to the link in the error you can seen the reason why:
Defining the Encoding
Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=
First thing to do is run this:
SHOW GRANTS;
You will quickly see you were assigned the anonymous user to authenticate into mysql.
Instead of logging into mysql with
mysql
login like this:
mysql -uroot
By default, root@localhost has all rights and no password.
If you cannot login as root without a password, do the following:
Step 01) Add the two options in the mysqld section of my.ini:
[mysqld]
skip-grant-tables
skip-networking
Step 02) Restart mysql
net stop mysql
<wait 10 seconds>
net start mysql
Step 03) Connect to mysql
mysql
Step 04) Create a password from root@localhost
UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit
Step 05) Restart mysql
net stop mysql
<wait 10 seconds>
net start mysql
Step 06) Login as root with password
mysql -u root -p
You should be good from there.
Declare globally delayed listener:
var resize_timeout;
$(window).on('resize orientationchange', function(){
clearTimeout(resize_timeout);
resize_timeout = setTimeout(function(){
$(window).trigger('resized');
}, 250);
});
And below use listeners to resized
event as you want:
$(window).on('resized', function(){
console.log('resized');
});
You can simply set the value in text box.
First, you get the value like
var getValue = $('#txt_name').val();
After getting a value set in input like
$('#txt_name').val(getValue);
Here is the method I use. It does not require any hidden DOM elements on the page, and only requires an anchor tag with the href of the modal partial, and a class of 'modalTrigger'. When the modal is closed (hidden) it is removed from the DOM.
(function(){
// Create jQuery body object
var $body = $('body'),
// Use a tags with 'class="modalTrigger"' as the triggers
$modalTriggers = $('a.modalTrigger'),
// Trigger event handler
openModal = function(evt) {
var $trigger = $(this), // Trigger jQuery object
modalPath = $trigger.attr('href'), // Modal path is href of trigger
$newModal, // Declare modal variable
removeModal = function(evt) { // Remove modal handler
$newModal.off('hidden.bs.modal'); // Turn off 'hide' event
$newModal.remove(); // Remove modal from DOM
},
showModal = function(data) { // Ajax complete event handler
$body.append(data); // Add to DOM
$newModal = $('.modal').last(); // Modal jQuery object
$newModal.modal('show'); // Showtime!
$newModal.on('hidden.bs.modal',removeModal); // Remove modal from DOM on hide
};
$.get(modalPath,showModal); // Ajax request
evt.preventDefault(); // Prevent default a tag behavior
};
$modalTriggers.on('click',openModal); // Add event handlers
}());
To use, just create an a tag with the href of the modal partial:
<a href="path/to/modal-partial.html" class="modalTrigger">Open Modal</a>

ugh, just to iterate over my own case, which gave out approximately the same error - in the Resource declaration (server.xml) make sure to NOT omit driverClassName, and that e.g. for Oracle it is "oracle.jdbc.OracleDriver", and that the right JAR file (e.g. ojdbc14.jar) exists in %CATALINA_HOME%/lib
def is_prime(num):
"""Returns True if the number is prime
else False."""
if num == 0 or num == 1:
return False
for x in range(2, num):
if num % x == 0:
return False
else:
return True
>> filter(is_prime, range(1, 20))
[2, 3, 5, 7, 11, 13, 17, 19]
We will get all the prime numbers upto 20 in a list. I could have used Sieve of Eratosthenes but you said you want something very simple. ;)
If this is in IIS, the app can get started before the debugger has attached. If so, I am not sure if you can thread sleep long enough to get attached.
In Visual Studio, you can attach the debugger to a process. You do this by clicking Debug >> Attach to process. Attach to the browser and then hit your application. To be safe, then restart IIS and hit the site. I am not 100% convinced this will solve the problem, but it will do much better than firing off a thread sleep in App_Start.
Another option is temporarily host in the built in web server until you finish debugging application start.
Try this:
keys=pygame.key.get_pressed()
if keys[K_LEFT]:
if count == 10:
location-=1
count=0
else:
count +=1
if location==-1:
location=0
if keys[K_RIGHT]:
if count == 10:
location+=1
count=0
else:
count +=1
if location==5:
location=4
This will mean you only move 1/10 of the time. If it still moves to fast you could try increasing the value you set "count" too.
clazz.isAssignableFrom(Foo.class)
will be true whenever the class represented by the clazz
object is a superclass or superinterface of Foo
.
clazz.isInstance(obj)
will be true whenever the object obj
is an instance of the class clazz
.
That is:
clazz.isAssignableFrom(obj.getClass()) == clazz.isInstance(obj)
is always true so long as clazz
and obj
are nonnull.
I created a small portable wrapper script called "xargsL" around "xargs" which addresses most of the problems.
Contrary to xargs, xargsL accepts one pathname per line. The pathnames may contain any character except (obviously) newline or NUL bytes.
No quoting is allowed or supported in the file list - your file names may contain all sorts of whitespace, backslashes, backticks, shell wildcard characters and the like - xargsL will process them as literal characters, no harm done.
As an added bonus feature, xargsL will not run the command once if there is no input!
Note the difference:
$ true | xargs echo no data
no data
$ true | xargsL echo no data # No output
Any arguments given to xargsL will be passed through to xargs.
Here is the "xargsL" POSIX shell script:
#! /bin/sh # Line-based version of "xargs" (one pathname per line which may contain any # amount of whitespace except for newlines) with the added bonus feature that # it will not execute the command if the input file is empty. # # Version 2018.76.3 # # Copyright (c) 2018 Guenther Brunthaler. All rights reserved. # # This script is free software. # Distribution is permitted under the terms of the GPLv3. set -e trap 'test $? = 0 || echo "$0 failed!" >& 2' 0 if IFS= read -r first then { printf '%s\n' "$first" cat } | sed 's/./\\&/g' | xargs ${1+"$@"} fi
Put the script into some directory in your $PATH and don't forget to
$ chmod +x xargsL
the script there to make it executable.
// Captura datos usando metodo GET en la url colocar index.html?hola=chao
const $_GET = {};
const args = location.search.substr(1).split(/&/);
for (let i=0; i<args.length; ++i) {
const tmp = args[i].split(/=/);
if (tmp[0] != "") {

I don't understand the concept of storing encrypted stuff in a cookie when it is the encrypted version of it that you need to do your hacking. If I'm missing something, please comment.
I am thinking about taking this approach to 'Remember Me'. If you can see any issues, please comment.
Create a table to store "Remember Me" data in - separate to the user table so that I can log in from multiple devices.
On successful login (with Remember Me ticked):
a) Generate a unique random string to be used as the UserID on this machine: bigUserID
b) Generate a unique random string: bigKey
c) Store a cookie: bigUserID:bigKey
d) In the "Remember Me" table, add a record with: UserID, IP Address, bigUserID, bigKey
If trying to access something that requires login:
a) Check for the cookie and search for bigUserID & bigKey with a matching IP address
b) If you find it, Log the person in but set a flag in the user table "soft login" so that for any dangerous operations, you can prompt for a full login.
On logout, Mark all the "Remember Me" records for that user as expired.
The only vulnerabilities that I can see is;
try changing the connection port to 8012
open xampp as administrator
Mysql config => my.ini change the port from 3306 to 8012
close and run it again I hope it will work.
Using a string of $index
can help to use a hashmap of selected values:
<ul>
<li ng-repeat="someItem in someArray">
<input type="checkbox" ng-model="someObject[$index.toString()]" />
</li>
</ul>
This way the ng-model object gets updated with the key representing the index.
$scope.someObject = {};
After a while $scope.someObject
should look something like:
$scope.someObject = {
0: true,
4: false,
1: true
};
This method won't work for all situations, but it is easy to implement.
You need to do custom SQL as exemplified in this snippet:
Or in a custom manager as shown in the online Django docs:
if you have no systemctl and started the docker daemon by:
sudo service docker start
you can stop it by:
sudo service docker stop
The documentation is quite sketchy as far as definitive resolutions go. After some research, here's the solution I came to: Android splash screen image sizes to fit all devices
It's basically guided towards splash screens, but it's perfectly applicable to images that should occupy full screen.

if 0<=x: return x**(1./3.)
return -(-x)**(1./3.)
print (cube(8))
print (cube(-8))
Here is the full answer for both negative and positive numbers.
>>>
2.0
-2.0
>>>
Or here is a one-liner;
root_cube = lambda x: x**(1./3.) if 0<=x else -(-x)**(1./3.)

Depending on what you're trying to do, you can either block with GetIdList().Result ( generally a bad idea, but it's hard to tell the context) or use a test framework that supports async test methods and have the test method do var results = await GetIdList();
Here is a suggestion, using TimeUnit
, to obtain each time part and format them.
private static String formatDuration(long duration) {
long hours = TimeUnit.MILLISECONDS.toHours(duration);
long minutes = TimeUnit.MILLISECONDS.toMinutes(duration) % 60;
long seconds = TimeUnit.MILLISECONDS.toSeconds(duration) % 60;
long milliseconds = duration % 1000;
return String.format("%02d:%02d:%02d,%03d", hours, minutes, seconds, milliseconds);
}
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss,SSS");
Date startTime = sdf.parse("01:00:22,427");
Date now = sdf.parse("02:06:38,355");
long duration = now.getTime() - startTime.getTime();
System.out.println(formatDuration(duration));
The result is: 01:06:15,928
in windows form application I do this, Right-click on Project->Properties->Build->Check Prefer 32-bit checkbox. Thanks all
The accepted answer works, but you have to do a "Select All" first -- every time -- and I'm way too lazy for that.
And it turns out, it's not super trivial -- I figured I'd post this here in an attempt to save like-minded individuals the 30 minutes it takes to track all this down. -- Also note: this approach restores the original selection when it's done (and it happens so fast, you don't even notice the selection was ever changed).
1.) First, add a custom command to your init script (File->Open Your Init Script, then paste this at the bottom):
atom.commands.add 'atom-text-editor', 'custom:reformat', ->
editor = atom.workspace.getActiveTextEditor();
oldRanges = editor.getSelectedBufferRanges();
editor.selectAll();
atom.commands.dispatch(atom.views.getView(editor), 'editor:auto-indent')
editor.setSelectedBufferRanges(oldRanges);
2.) Bind "custom:reformat" to a key (File->Open Your Keymap, then paste this at the bottom):
'atom-text-editor':
'ctrl-alt-d': 'custom:reformat'
3.) Restart Atom (the init.coffee script only runs when atom is first launched).
No.
The content-type should be whatever it is known to be, if you know it. application/octet-stream
is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.
You can combine the use of Content-Disposition
with other content-types, such as image/png
or even text/html
to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html
but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).
RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline
to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename
part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.
Hence:
Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"
Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".
Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"
Means "This is a PNG image. Please save it as a file, preferably named picture.png".
Content-Type: image/png
Content-Disposition: inline; filename="picture.png"
Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".
Of those browsers that recognise inline
some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).
In C, using a previously undeclared function constitutes an implicit declaration of the function. In an implicit declaration, the return type is int
if I recall correctly. Now, GCC has built-in definitions for some standard functions. If an implicit declaration does not match the built-in definition, you get this warning.
To fix the problem, you have to declare the functions before using them; normally you do this by including the appropriate header. I recommend not to use the -fno-builtin-*
flags if possible.
Instead of stdlib.h, you should try:
#include <string.h>
That's where strcpy
and strncpy
are defined, at least according to the strcpy
(2) man page.
The exit
function is defined in stdlib.h, though, so I don't know what's going on there.

Use transactions and keep a number in the database somewhere that you can increase by one. This way you can get a nice numeric and simple id.
Optimized (but less readable) implementation:
function base64toBlob(base64Data, contentType) {
contentType = contentType || '';
var sliceSize = 1024;
var byteCharacters = atob(base64Data);
var bytesLength = byteCharacters.length;
var slicesCount = Math.ceil(bytesLength / sliceSize);
var byteArrays = new Array(slicesCount);
for (var sliceIndex = 0; sliceIndex < slicesCount; ++sliceIndex) {
var begin = sliceIndex * sliceSize;
var end = Math.min(begin + sliceSize, bytesLength);
var bytes = new Array(end - begin);
for (var offset = begin, i = 0; offset < end; ++i, ++offset) {
bytes[i] = byteCharacters[offset].charCodeAt(0);
}
byteArrays[sliceIndex] = new Uint8Array(bytes);
}
return new Blob(byteArrays, { type: contentType });
}
Make sure both your System and User paths are set correctly.
EDIT: Note, this is if you have multiple tsconfig.json files in your typescript source. For my project we have each tsconfig.json file compile to a differently-named .js file. This makes watching every typescript file really easy.
I wrote a sweet bash script that finds all of your tsconfig.json files and runs them in the background, and then if you CTRL+C the terminal it will close all the running typescript watch commands.
This is tested on MacOS, but should work anywhere that BASH 3.2.57 is supported. Future versions may have changed some things, so be careful!
#!/bin/bash
# run "chmod +x typescript-search-and-compile.sh" in the directory of this file to ENABLE execution of this script
# then in terminal run "path/to/this/file/typescript-search-and-compile.sh" to execute this script
# (or "./typescript-search-and-compile.sh" if your terminal is in the folder the script is in)
# !!! CHANGE ME !!!
# location of your scripts root folder
# make sure that you do not add a trailing "/" at the end!!
# also, no spaces! If you have a space in the filepath, then
# you have to follow this link: https://stackoverflow.com/a/16703720/9800782
sr=~/path/to/scripts/root/folder
# !!! CHANGE ME !!!
# find all typescript config files
scripts=$(find $sr -name "tsconfig.json")
for s in $scripts
do
# strip off the word "tsconfig.json"
cd ${s%/*} # */ # this function gets incorrectly parsed by style linters on web
# run the typescript watch in the background
tsc -w &
# get the pid of the last executed background function
pids+=$!
# save it to an array

done
# end all processes we spawned when you close this process

Finally, this asserts that we're now at the end of the subjectWhen you're testing regular expressions, you'll likely find a tool like regexpal helpful. This allows you to see your regular expression match (or fail to match) your sample data in real time as you write it.
map()
doesn't return a list, it returns a map
object.
You need to call list(map)
if you want it to be a list again.
Even better,
from itertools import imap
payIntList = list(imap(int, payList))
Won't take up a bunch of memory creating an intermediate object, it will just pass the ints
out as it creates them.
Also, you can do if choice.lower() == 'n':
so you don't have to do it twice.
Python supports +=
: you can do payIntList[i] += 1000
and numElements += 1
if you want.
If you really want to be tricky:
from itertools import count
for numElements in count(1):
payList.append(raw_input("Enter the pay amount: "))
if raw_input("Do you wish to continue(y/n)?").lower() == 'n':
break
and / or
for payInt in payIntList:
payInt += 1000
print payInt
Also, four spaces is the standard indent amount in Python.
Create an array to store the objects:
ArrayList<MyObject> list = new ArrayList<MyObject>();
In a single step:
list.add(new MyObject (1, 2, 3)); //Create a new object and adding it to list.
or
MyObject myObject = new MyObject (1, 2, 3); //Create a new object.
list.add(myObject); // Adding it to the list.
Actually, the HTML 4.01 spec says that these attributes do not require values. I haven't personally encountered a situation where providing a value rendered these controls as unselected.
Here are the respective links to the spec document for selected and checked.
Edit: Firebug renders the checkbox as checked regardless of any values I put in quotes for the checked attribute (including just typing "checked" with no values whatsoever), and IE 8's Developer Tools forces checked="checked". I'm not sure if any similar tools exist for other browsers that might alter the rendered state of a checkbox, however.
You can execute 'tree' command of Linux shell.
Installation:
~$sudo apt install tree
Using in python
>>> import os
>>> os.system('tree <desired path>')
Example:
>>> os.system('tree ~/Desktop/myproject')
This gives you a cleaner structure and is visually more comprehensive and easy to type.

Make sure opencv-python is installed in path(\Python\Python36\Lib\site-packages), you will find cv2 folder over there.

echo substr(uniqid(),-6); // result: 5ebf06

I was trying to create a complex grid of panes and had to deal with switching and splitting panes over and over again. Here are my learnings:
tmux new-session \;
Gets you started with a new session. To split it horizontal or vertical use split-window -h
or -v
subsequently, like that:
tmux new-session \; split-window -v \; split-window -h \;
Creates 3 panes, like this:
------------
| |
|----------|
| | |
------------
To run commands in that panes, just add them with the send-keys 'my-command'
command and C-m
which executes it:
tmux new-session \; \
send-keys 'tail -f /var/log/monitor.log' C-m \; \
split-window -v \; \
split-window -h \; \
send-keys 'top' C-m \;
And the resulting session should look like that.
------------
| tail |
|----------|
| | top |
------------
Now I tried to again sub-divide the bottom left pane, so switching either back using last-pane
, or in more complex windows, with the select-pane -t 1
where 1
is the number of the pane in order created starting with 0
.
tmux new-session \; \
send-keys 'tail -f /var/log/monitor.log' C-m \; \
split-window -v \; \
split-window -h \; \
send-keys 'top' C-m \; \
select-pane -t 1 \; \
split-window -v \; \
send-keys 'weechat' C-m \;
Does that. Basicaly knowing your way around with split-window
and select-pane
is all you need. It's also handy to pass with -p 75
a percentage size of the pane created by split-window
to have more control over the size of the panes.
tmux new-session \; \
send-keys 'tail -f /var/log/monitor.log' C-m \; \
split-window -v -p 75 \; \
split-window -h -p 30 \; \
send-keys 'top' C-m \; \
select-pane -t 1 \; \
split-window -v \; \
send-keys 'weechat' C-m \;
Which results in a session looking like that
------------------
| tail |
|----------------|
| | top |
|----------| |
| weechat | |
------------------
Hope that helps tmux
enthusiasts in the future.

Well, I digged deeper, and found sources of PackageInstaller application from Android Source.
https://github.com/android/platform_packages_apps_packageinstaller
From manifest I found that it require permission:
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
And the actual process of installation occurs after confirmation
Intent newIntent = new Intent();
newIntent.putExtra(PackageUtil.INTENT_ATTR_APPLICATION_INFO, mPkgInfo.applicationInfo);
newIntent.setData(mPackageURI);
newIntent.setClass(this, InstallAppProgress.class);
String installerPackageName = getIntent().getStringExtra(Intent.EXTRA_INSTALLER_PACKAGE_NAME);
if (installerPackageName != null) {
newIntent.putExtra(Intent.EXTRA_INSTALLER_PACKAGE_NAME, installerPackageName);
}
startActivity(newIntent);
You need to cast it to a string (not an array of string) since it's a single value.
var cellValue = (string)(excelWorksheet.Cells[10, 2] as Excel.Range).Value;
Temp table variable is saved to the temp.db and the scope is limited to the current execution. Hence, unlike dropping a Temp tables e.g drop table #tempTable, we don't have to explicitly drop Temp table variable @tempTableVariable. It is automatically taken care by the sql server.
drop table @tempTableVariable -- Invalid
As stated already, running your code through the W3C Validator is great but if your page is complex, you still may not know exactly where to find the open div.
I like using tabs to indent my code. It keeps it visually organized so that these issues are easier to find, children, siblings, parents, etc... they'll appear more obvious.
EDIT: Also, I'll use a few HTML comments to mark closing tags in the complex areas. I keep these to a minimum for neatness.

This may appear like a joke at the first glance, but it may actually be useful. For me it turned out to be helpful to think about what methods do even for private methods (unless really trivial, of course).

Upgrading from Kepler to Luna worked for me.
I had just added some components for Java 1.8 support. It seems that they where not as compatible as I would like or that I mixed the wrong ones. It really caused a lot of problems. Trying to update the system reported errors as they couldn't fulfill some dependencies. Maven upgrades didn't work. Tried a lot of things.
So, if there is no reason to avoid the upgrade just add the luna repository to avalilable software sites (Luna http://download.eclipse.org/releases/luna/ ) and "check for updates". It is better to have all the components with the same version and there are some nice new features.

you can permanently solution your problem by editing my.ini file[Mysql configuration file] change variables max_connections = 10000;
or
login into MySQL using command line -
mysql -u [username] -p
**** [MySQL password]
put the below command into MySQL window
SET GLOBAL max_connect_errors=10000;
set global max_connections = 200;
check veritable using command-
show variables like "max_connections";
show variables like "max_connect_errors";
the core functions are getBytes(String charset)
and new String(byte[] data)
. you can use these functions to do UTF-8 decoding.
UTF-8 decoding actually is a string to string conversion, the intermediate buffer is a byte array. since the target is an UTF-8 string, so the only parameter for new String()
is the byte array, which calling is equal to new String(bytes, "UTF-8")
Then the key is the parameter for input encoded string to get internal byte array, which you should know beforehand. If you don't, guess the most possible one, "ISO-8859-1" is a good guess for English user.
The decoding sentence should be
String decoded = new String(encoded.getBytes("ISO-8859-1"));
This is to synchronize IOs from C and C++ world. If you synchronize, then you have a guaranty that the orders of all IOs is exactly what you expect. In general, the problem is the buffering of IOs that causes the problem, synchronizing let both worlds to share the same buffers. For example cout << "Hello"; printf("World"); cout << "Ciao";
; without synchronization you'll never know if you'll get HelloCiaoWorld
or HelloWorldCiao
or WorldHelloCiao
...
tie
lets you have the guaranty that IOs channels in C++ world are tied one to each other, which means for example that every output have been flushed before inputs occurs (think about cout << "What's your name ?"; cin >> name;
).
You can always mix C or C++ IOs, but if you want some reasonable behavior you must synchronize both worlds. Beware that in general it is not recommended to mix them, if you program in C use C stdio, and if you program in C++ use streams. But you may want to mix existing C libraries into C++ code, and in such a case it is needed to synchronize both.
If I understand your problem correctly, you are trying to restore (transact sql) xyz.sql - database + schema. You can try this command which worked for me:
SQLCMD -U sa -i xyz.sql
For what you want I would've used
app.get('/fruit/:fruitName&:fruitColor', function(request, response) {
const name = request.params.fruitName
const color = request.params.fruitColor
});
or better yet
app.get('/fruit/:fruit', function(request, response) {
const fruit = request.params.fruit
console.log(fruit)
});
where fruit is a object. So in the client app you just call
https://mydomain.dm/fruit/{"name":"My fruit name", "color":"The color of the fruit"}
and as a response you should see:
// client side response
// { name: My fruit name, color:The color of the fruit}
Ok it turns out I was doing something stupid. I hadn't appended the new file name to the path.
I had
rootDirectory = "C:\\safesite_documents"
but it should have been
rootDirectory = "C:\\safesite_documents\\newFile.jpg"
Sorry it was a stupid mistake as always.
The background-image of a div element will load if the div is set do 'display:none'.
Anyway, if that same div has a parent and that parent is set to 'display:none', the background-image of the child element will not load. :)

I had this problem couple of weeks ago. I first tried the troubleshooting on the Android developer site, but without luck. After that I reinstalled the Android SDK, which solved my problem.
There is no difference. A primary key is a candidate key. By convention one candidate key in a relation is usually chosen to be the "primary" one but the choice is essentially arbitrary and a matter of convenience for database users/designers/developers. It doesn't make a "primary" key fundamentally any different to any other candidate key.
How about
if value in my_array[:, col_num]:
do_whatever
Edit: I think __contains__
is implemented in such a way that this is the same as @detly's version
Well, you need to incorporate exec-maven-plugin
, this plug-in performs the same thing that you do on command prompt when you type in java -cp .;jarpaths TestMain
. You can pass argument and define which phase (test
, package
, integration
, verify
, or deploy
), you want this plug-in to call your main class.
You need to add this plug-in under <build>
tag and specify parameters. For example
<project>
...
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1.1</version>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>my.company.name.packageName.TestMain</mainClass>
<arguments>
<argument>myArg1</argument>
<argument>myArg2</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
...
</project>
Now, if you right-click on on the project folder and do Run As > Maven Test
, or Run As > Maven Package
or Run As > Maven Install
, the test phase
will execute and so your Main class.
Two observations:
You should write
<input type="button" value="button text" />
instead of
<input type="button">button text</input>
You should rename your function. The function click()
is already defined on a button (it simulates a click), and gets a higher priority then your method.
Note that there are a couple of suggestions here that are plain wrong, and you shouldn't spend to much time on them:
onclick="javascript:myfunc()"
. Only use the javascript:
prefix inside the href
attribute of a hyperlink: <a href="javascript:myfunc()">
.onclick="foo()"
and onclick="foo();"
both work just fine.onclick
, onClick
and ONCLICK
all work. It is common practice to write attributes in lowercase: onclick
. note that javascript itself is case sensitive, so if you write document.getElementById("...").onclick = ...
, then it must be all lowercase.In case than you want to store a complex command to compare text result, for example to compare the version of OS, maybe this can help you:
tasks:
- shell: echo $(cat /etc/issue | awk {'print $7'})
register: echo_content
- shell: echo "It works"
when: echo_content.stdout == "12"
register: out
- debug: var=out.stdout_lines
Short answer: use an unassigned user port
Over achiever's answer - Select and deploy a resource discovery solution. Have the server select a private port dynamically. Have the clients use resource discovery.
The risk that that a server will fail because the port it wants to listen on is not available is real; at least it's happened to me. Another service or a client might get there first.
You can almost totally reduce the risk from a client by avoiding the private ports, which are dynamically handed out to clients.
The risk that from another service is minimal if you use a user port. An unassigned port's risk is only that another service happens to be configured (or dyamically) uses that port. But at least that's probably under your control.
The huge doc with all the port assignments, including User Ports, is here: http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.txt look for the token Unassigned.
There is another type-safe alternative to specifying a base-package location as a String. See the API here, but I've also illustrated below:
@ComponentScan(basePackageClasses = {ExampleController.class, ExampleModel.class, ExmapleView.class})
Using the basePackageClasses specifier with your class references will tell Spring to scan those packages (just like the mentioned alternatives), but this method is both type-safe and adds IDE support for future refactoring -- a huge plus in my book.
Reading from the API, Spring suggests creating a no-op marker class or interface in each package you wish to scan that serves no other purpose than to be used as a reference for/by this attribute.
IMO, I don't like the marker-classes (but then again, they are pretty much just like the package-info classes) but the type safety, IDE support, and drastically reducing the number of base packages needed to include for this scan is, with out a doubt, a far better option.
This is what's killing you:
task.Wait();
That's blocking the UI thread until the task has completed - but the task is an async method which is going to try to get back to the UI thread after it "pauses" and awaits an async result. It can't do that, because you're blocking the UI thread...
There's nothing in your code which really looks like it needs to be on the UI thread anyway, but assuming you really do want it there, you should use:
private async void Button_Click(object sender, RoutedEventArgs
{
Task<List<MyObject>> task = GetResponse<MyObject>("my url");
var items = await task;
// Presumably use items here
}
Or just:
private async void Button_Click(object sender, RoutedEventArgs
{
var items = await GetResponse<MyObject>("my url");
// Presumably use items here
}
Now instead of blocking until the task has completed, the Button_Click
method will return after scheduling a continuation to fire when the task has completed. (That's how async/await works, basically.)
Note that I would also rename GetResponse
to GetResponseAsync
for clarity.
One way is to use a Boolean series to index the column df['one']
. This gives you a new column where the True
entries have the same value as the same row as df['one']
and the False
values are NaN
.
The Boolean series is just given by your if
statement (although it is necessary to use &
instead of and
):
>>> df['que'] = df['one'][(df['one'] >= df['two']) & (df['one'] <= df['three'])]
>>> df
one two three que
0 10 1.2 4.2 10
1 15 70 0.03 NaN
2 8 5 0 NaN
If you want the NaN
values to be replaced by other values, you can use the fillna
method on the new column que
. I've used 0
instead of the empty string here:
>>> df['que'] = df['que'].fillna(0)
>>> df
one two three que
0 10 1.2 4.2 10
1 15 70 0.03 0
2 8 5 0 0
Try this:
v=spf1 ip4:abc.de.fgh.ij ip4:klm.no.pqr.st ~all
one possibly simple method ( that may not meet different users needs ) is the use of shell PROMPT.it is a simple solution that can be useful in some cases. You can use the bash prompting feature as in the example below:
export PS1='[\t \u@\h]\$'
The above command will result in changing the shell prompt to :
[HH:MM:SS username@hostname]$
Each time you run a command (or hit enter) returning back to the shell prompt, the prompt will display current time.
notes:
1) beware that if you waited for sometime before you type your next command, then this time need to be considered, i.e the time displayed in the shell prompt is the timestamp when the shell prompt was displayed, not when you enter command. some users choose to hit Enter key to get a new prompt with a new timestamp before they are ready for the next command.
2) There are other available options and modifiers that can be used to change the bash prompt, refer to ( man bash ) for more details.
You don't want regular expressions here.

Surely you just need:
double seconds = milliseconds / 1000.0;
There's no need to manually do the two parts separately - you just need floating point arithmetic, which the use of 1000.0
(as a double
literal) forces. (I'm assuming your milliseconds
value is an integer of some form.)
Note that as usual with double
, you may not be able to represent the result exactly. Consider using BigDecimal
if you want to represent 100ms as 0.1 seconds exactly. (Given that it's a physical quantity, and the 100ms wouldn't be exact in the first place, a double
is probably appropriate, but...)
For me it worked when I omitted the password.
So mysqldump -u user dbname > dump.sql
As pointed out by @Jayan in another post, the solution was to do the following
import jenkins.model.*
jenkins = Jenkins.instance
Then I was able to do the rest of my scripting the way it was.
The other answers show you how to make a list of data.frames when you already have a bunch of data.frames, e.g., d1
, d2
, .... Having sequentially named data frames is a problem, and putting them in a list is a good fix, but best practice is to avoid having a bunch of data.frames not in a list in the first place.
The other answers give plenty of detail of how to assign data frames to list elements, access them, etc. We'll cover that a little here too, but the Main Point is to say don't wait until you have a bunch of a data.frames
to add them to a list. Start with the list.
The rest of the this answer will cover some common cases where you might be tempted to create sequential variables, and show you how to go straight to lists. If you're new to lists in R, you might want to also read What's the difference between [[
and [
in accessing elements of a list?.
Don't ever create d1
d2
d3
, ..., dn
in the first place. Create a list d
with n
elements.
This is done pretty easily when reading in files. Maybe you've got files data1.csv, data2.csv, ...
in a directory. Your goal is a list of data.frames called mydata
. The first thing you need is a vector with all the file names. You can construct this with paste (e.g., my_files = paste0("data", 1:5, ".csv")
), but it's probably easier to use list.files
to grab all the appropriate files: my_files <- list.files(pattern = "\\.csv$")
. You can use regular expressions to match the files, read more about regular expressions in other questions if you need help there. This way you can grab all CSV files even if they don't follow a nice naming scheme. Or you can use a fancier regex pattern if you need to pick certain CSV files out from a bunch of them.
At this point, most R beginners will use a for
loop, and there's nothing wrong with that, it works just fine.
my_data <- list()
for (i in seq_along(my_files)) {
my_data[[i]] <- read.csv(file = my_files[i])
}
A more R-like way to do it is with lapply
, which is a shortcut for the above
my_data <- lapply(my_files, read.csv)
Of course, substitute other data import function for read.csv
as appropriate. readr::read_csv
or data.table::fread
will be faster, or you may also need a different function for a different file type.
Either way, it's handy to name the list elements to match the files
names(my_data) <- gsub("\\.csv$", "", my_files)
# or, if you prefer the consistent syntax of stringr
names(my_data) <- stringr::str_replace(my_files, pattern = ".csv", replacement = "")
This is super-easy, the base function split()
does it for you. You can split by a column (or columns) of the data, or by anything else you want
mt_list = split(mtcars, f = mtcars$cyl)
# This gives a list of three data frames, one for each value of cyl
This is also a nice way to break a data frame into pieces for cross-validation. Maybe you want to split mtcars
into training, test, and validation pieces.
groups = sample(c("train", "test", "validate"),
size = nrow(mtcars), replace = TRUE)
mt_split = split(mtcars, f = groups)
# and mt_split has appropriate names already!
Maybe you're simulating data, something like this:
my_sim_data = data.frame(x = rnorm(50), y = rnorm(50))
But who does only one simulation? You want to do this 100 times, 1000 times, more! But you don't want 10,000 data frames in your workspace. Use replicate
and put them in a list:
sim_list = replicate(n = 10,
expr = {data.frame(x = rnorm(50), y = rnorm(50))},
simplify = F)
In this case especially, you should also consider whether you really need separate data frames, or would a single data frame with a "group" column work just as well? Using data.table
or dplyr
it's quite easy to do things "by group" to a data frame.
If they're an odd assortment (which is unusual), you can simply assign them:
mylist <- list()
mylist[[1]] <- mtcars
mylist[[2]] <- data.frame(a = rnorm(50), b = runif(50))
...
If you have data frames named in a pattern, e.g., df1
, df2
, df3
, and you want them in a list, you can get
them if you can write a regular expression to match the names. Something like
df_list = mget(ls(pattern = "df[0-9]"))
# this would match any object with "df" followed by a digit in its name
# you can test what objects will be got by just running the
ls(pattern = "df[0-9]")
# part and adjusting the pattern until it gets the right objects.
Generally, mget
is used to get multiple objects and return them in a named list. Its counterpart get
is used to get a single object and return it (not in a list).
A common task is combining a list of data frames into one big data frame. If you want to stack them on top of each other, you would use rbind
for a pair of them, but for a list of data frames here are three good choices:
# base option - slower but not extra dependencies
big_data = do.call(what = rbind, args = df_list)
# data table and dplyr have nice functions for this that
# - are much faster
# - add id columns to identify the source
# - fill in missing values if some data frames have more columns than others
# see their help pages for details
big_data = data.table::rbindlist(df_list)
big_data = dplyr::bind_rows(df_list)
(Similarly using cbind
or dplyr::bind_cols
for columns.)
To merge (join) a list of data frames, you can see these answers. Often, the idea is to use Reduce
with merge
(or some other joining function) to get them together.
Put similar data in lists because you want to do similar things to each data frame, and functions like lapply
, sapply
do.call
, the purrr
package, and the old plyr
l*ply
functions make it easy to do that. Examples of people easily doing things with lists are all over SO.
Even if you use a lowly for loop, it's much easier to loop over the elements of a list than it is to construct variable names with paste
and access the objects with get
. Easier to debug, too.
Think of scalability. If you really only need three variables, it's fine to use d1
, d2
, d3
. But then if it turns out you really need 6, that's a lot more typing. And next time, when you need 10 or 20, you find yourself copying and pasting lines of code, maybe using find/replace to change d14
to d15
, and you're thinking this isn't how programming should be. If you use a list, the difference between 3 cases, 30 cases, and 300 cases is at most one line of code---no change at all if your number of cases is automatically detected by, e.g., how many .csv
files are in your directory.
You can name the elements of a list, in case you want to use something other than numeric indices to access your data frames (and you can use both, this isn't an XOR choice).
Overall, using lists will lead you to write cleaner, easier-to-read code, which will result in fewer bugs and less confusion.
For me what works here is to using a version manager such as pyenv, which I strongly recommend to get your project environments and package versions well managed and separate from that of the operative system.
I had this same error after an OS update, but was easily fixed with pyenv install 3.7-dev
(the version I use).
You should try to avoid using Singletons, but if you ever do need to, Lazy<T>
makes implementing lazy, thread-safe singletons easy:
public sealed class Singleton
{
// Because Singleton's constructor is private, we must explicitly
// give the Lazy<Singleton> a delegate for creating the Singleton.
static readonly Lazy<Singleton> instanceHolder =
new Lazy<Singleton>(() => new Singleton());
Singleton()
{
// Explicit private constructor to prevent default public constructor.
...
}
public static Singleton Instance => instanceHolder.Value;
}
If the array contains integers, the value cannot be NULL. NULL can be used if the array contains pointers.
SomeClass* myArray[2];
myArray[0] = new SomeClass();
myArray[1] = NULL;
if (myArray[0] != NULL) { // this will be executed }
if (myArray[1] != NULL) { // this will NOT be executed }
As http://en.cppreference.com/w/cpp/types/NULL states, NULL is a null pointer constant!
ping -n 11 -w 1000 127.0.0.1 > nul
Update
Beginner's mistake. Ping doesn't wait 1000 ms before or after an request, but inbetween requests. So to wait 10 seconds, you'll have to do 11 pings to have 10 'gaps' of a second inbetween.
It should work - as long as the data variable is actually an array containing a dictionary with the key SPORT
NSArray *data = [NSArray arrayWithObject:[NSMutableDictionary dictionaryWithObject:@"foo" forKey:@"BAR"]];
NSArray *filtered = [data filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(BAR == %@)", @"foo"]];
Filtered in this case contains the dictionary.
(the %@ does not have to be quoted, this is done when NSPredicate creates the object.)
Well I would atleast clean it up as follows:
print "%.2f kg = %.2f lb = %.2f gal = %.2f l" % (var1, var2, var3, var4)
The native library file name has to correspond to the Jar file name. This is very very important. Please make sure that jar name and dll name are same. Also,please see the post from Fabian Steeg My download for jawin was containing different names for dll and jar. It was jawin.jar and jawind.dll, note extra 'd' in dll file name. I simply renamed it to jawin.dll and set it as a native library in eclipse as mentioned in post "http://www.eclipsezone.com/eclipse/forums/t49342.html"
[It turns out my answer is similar to @Anonymous, but I keep my answer here since it explains how I got my answer].
The original object has THREE properties (i.e. 3 keys and 3 values). This suggest we should be using Object.keys()
to transform it to an array with 3 values.
var dataArray = Object.keys(dataObject);
// Gives: ["object1", "object2", "object3" ]
We now have 3 values, but not the 3 values we're after. So, this suggest we should use Array.prototype.map()
.
var dataArray = Object.keys(dataObject).map(function(e) { return dataObject[e]; } );
// Gives: [{"id":1,"name":"Fred"},{"id":2,"name":"Wilma"},{"id":3,"name":"Pebbles"}]
If you get code behind, use some like this
MyCustomObject myObject = new MyCustomObject();
myObject.name='try';
//OBJECT -> JSON
var javaScriptSerializer = new System.Web.Script.Serialization.JavaScriptSerializer();
string myObjectJson = javaScriptSerializer.Serialize(myObject);
//return JSON
Response.Clear();
Response.ContentType = "application/json; charset=utf-8";
Response.Write(myObjectJson );
Response.End();
So you return a json object serialized with all attributes of MyCustomObject.
400 is the best choice in both cases. If you want to further clarify the error you can either change the Reason Phrase or include a body to explain the error.
412 - Precondition failed is used for conditional requests when using last-modified date and ETags.
403 - Forbidden is used when the server wishes to prevent access to a resource.
The only other choice that is possible is 422 - Unprocessable entity.
This is a hard question to answer definitively because the terms and often misused or confused.
Often, an emulator is a complete re-implementation of a particular device or platform. The emulator acts exactly like the real device would. For example, a NES emulator implements the CPU, the sound chip, the video output, the controller signals, etc. The unmodified code from a NES castridge can be dumped and then the resulting image can be loaded into our emulator and played.
A simulator is a partial implementation of a device/platform, it does just enough for its own purposes. For example, the iPhone Simulator runs an "iPhone app" that has been specifically compiled to target x86 and the Cocoa API rather than the real device's ARM CPU and Cocoa Touch API. However, the binary that we run in the simulator would not work on the real device.
This is for those who came here from google search.
If you use maven just add the following
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.5</version>
</dependency>
Or
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.6.4</version>
</dependency>
instead of these custom error messages we can specify the type of the text field.
Ex: set type of the field in to type = 'email'
then plugin will identify the field and validate correctly.
Keeping the code simple is always my advice:
If IsNull(Me.Id) = True Then
DoCmd.GoToRecord , , acNext
Else
DoCmd.GoToRecord , , acLast
End If
ruby on rails notes has a very nice blogpost about commenting in erb-files
the short version is
to comment a single line use
<%# commented line %>
to comment a whole block use a if false
to surrond your code like this
<% if false %>
code to comment
<% end %>
The normal idea would be to run the command and then use $?
to get the exit code. However, some times you have multiple cases in which you need to get the exit code. For example, you might need to hide it's output but still return the exit code, or print both the exit code and the output.
ec() { [[ "$1" == "-h" ]] && { shift && eval $* > /dev/null 2>&1; ec=$?; echo $ec; } || eval $*; ec=$?; }
This will give you the option to suppress the output of the command you want the exit code for. When the output is suppressed for the command, the exit code will directly be returned by the function.
I personally like to put this function in my .bashrc
file
Below I demonstrate a few ways in which you can use this:
# In this example, the output for the command will be
# normally displayed, and the exit code will be stored
# in the variable $ec.
$ ec echo test
test
$ echo $ec
0
# In this example, the exit code is output
# and the output of the command passed
# to the `ec` function is suppressed.
$ echo "Exit Code: $(ec -h echo test)"
Exit Code: 0
# In this example, the output of the command
# passed to the `ec` function is suppressed
# and the exit code is stored in `$ec`
$ ec -h echo test
$ echo $ec
0
Solution to your code using this function
#!/bin/bash
if [[ "$(ec -h 'ls -l | grep p')" != "0" ]]; then
echo "Error when executing command: 'grep p' [$ec]"
exit $ec;
fi
You should also note that the exit code you will be seeing will be for the
grep
command that's being run, as it is the last command being executed. Not thels
.
If you throw the exception, the method execution will stop and the exception is thrown to the caller method. throw
always interrupt the execution flow of the current method. a try
/catch
block is something you could write when you call a method that may throw an exception, but throwing an exception just means that method execution is terminated due to an abnormal condition, and the exception notifies the caller method of that condition.

This answer is technically similar or equal to what jcoffland answered. I just added a query to detect if a script is already present or not. I need this because I work in an intranet website with a couple of modules, of which some are sharing scripts or bring their own, but these scripts do not need to be loaded everytime again. I am using this snippet since more than a year in production environment, it works like a charme. Commenting to myself: Yes I know, it would be more correct to ask if a function exists... :-)
if (!$('head > script[src="js/jquery.searchable.min.js"]').length) {
$('head').append($('<script />').attr('src','js/jquery.searchable.min.js'));
}
You could just capture window resize events and set the size of your canvas to be the browser's viewport.
Take a look at https://www.json.org
[edited] Imagine that you have a simple Java class like this:
public class Person {
private String name;
private Integer age;
public String getName() { return this.name; }
public void setName( String name ) { this.name = name; }
public Integer getAge() { return this.age; }
public void setAge( Integer age ) { this.age = age; }
}
So, to transform it to a JSon object, it's very simple. Like this:
import org.json.JSONObject;
public class JsonTest {
public static void main( String[] args ) {
Person person = new Person();
person.setName( "Person Name" );
person.setAge( 333 );
JSONObject jsonObj = new JSONObject( person );
System.out.println( jsonObj );
}
}
Hope it helps.
[edited] Here there is other example, in this case using Jackson: https://brunozambiazi.wordpress.com/2015/08/15/working-with-json-in-java/
Maven:

pip install PyYAML
If libyaml is not found or compiled PyYAML can do without it on Mavericks.
FailedPreconditionError: Attempting to use uninitialized value is one of the most frequent errors related to tensorflow. From official documentation, FailedPreconditionError
This exception is most commonly raised when running an operation that reads a tf.Variable before it has been initialized.
In your case the error even explains what variable was not initialized: Attempting to use uninitialized value Variable_1
. One of the TF tutorials explains a lot about variables, their creation/initialization/saving/loading
Basically to initialize the variable you have 3 options:
tf.global_variables_initializer()
tf.variables_initializer(list_of_vars)
. Notice that you can use this function to mimic global_variable_initializer: tf.variable_initializers(tf.global_variables())
var_name.initializer
I almost always use the first approach. Remember you should put it inside a session run. So you will get something like this:
with tf.Session() as sess:
sess.run(tf.global_variables_initializer())
If your are curious about more information about variables, read this documentation to know how to report_uninitialized_variables
and check is_variable_initialized
.
If you already have a JavaScript function called showImage
defined to show the image, you can link as such:
<a href="javascript:showImage()">show image</a>
If you need help defining the function, I would try:
function showImage() {
var img = document.getElementById('myImageId');
img.style.visibility = 'visible';
}
Or, better yet,
function setImageVisible(id, visible) {
var img = document.getElementById(id);
img.style.visibility = (visible ? 'visible' : 'hidden');
}
Then, your links would be:
<a href="javascript:setImageVisible('myImageId', true)">show image</a>
<a href="javascript:setImageVisible('myImageId', false)">hide image</a>

)I hit this same issue. Reading around here I realised it was file permissions the message was referring to. The fix , for me, was in:
/etc/inetd.d/git-gpv
It was starting git-daemon as user 'nobody' so lacked the write permission.
# Who When What
# GPV 20Nov13 Created this by hand while reading: http://linuxclues.blogspot.co.uk/2013/06>/git-daemon-ssh-create-repository-debian.html
# GPV 20Nov13 Changed owner (to user_git) otherise nobody lack permission to update the repository

git stream tcp nowait user_git /usr/bin/git git daemon --inetd --verbose --enable=receive-pack --export-all /gitrepo
(I doubt other call their inetd conf file git-gpv . Commonly it would be directly in /etc/inetd.conf)
As stated in many other responses, m_ is a prefix that denotes member variables. It is/was commonly used in the C++ world and propagated to other languages too, including Java.
In a modern IDE it is completely redundant as the syntax highlighting makes it evident which variables are local and which ones are members. However, by the time syntax highlighting appeared in the late 90s, the convention had been around for many years and was firmly set (at least in the C++ world).
I do not know which tutorials you are referring to, but I will guess that they are using the convention due to one of two factors:
When you use strace (on Linux) to run your binary, it will output the returns from system calls and what the error number means. This may sometimes be useful to you.
struct
and typedef
are two very different things.
The struct
keyword is used to define, or to refer to, a structure type. For example, this:
struct foo {
int n;
};
creates a new type called struct foo
. The name foo
is a tag; it's meaningful only when it's immediately preceded by the struct
keyword, because tags and other identifiers are in distinct name spaces. (This is similar to, but much more restricted than, the C++ concept of namespace
s.)
A typedef
, in spite of the name, does not define a new type; it merely creates a new name for an existing type. For example, given:
typedef int my_int;
my_int
is a new name for int
; my_int
and int
are exactly the same type. Similarly, given the struct
definition above, you can write:
typedef struct foo foo;
The type already has a name, struct foo
. The typedef
declaration gives the same type a new name, foo
.
The syntax allows you to combine a struct
and typedef
into a single declaration:
typedef struct bar {
int n;
} bar;
This is a common idiom. Now you can refer to this structure type either as struct bar
or just as bar
.
Note that the typedef name doesn't become visible until the end of the declaration. If the structure contains a pointer to itself, you have use the struct
version to refer to it:
typedef struct node {
int data;
struct node *next; /* can't use just "node *next" here */
} node;
Some programmers will use distinct identifiers for the struct tag and for the typedef name. In my opinion, there's no good reason for that; using the same name is perfectly legal and makes it clearer that they're the same type. If you must use different identifiers, at least use a consistent convention:
typedef struct node_s {
/* ... */
} node;
(Personally, I prefer to omit the typedef
and refer to the type as struct bar
. The typedef
save a little typing, but it hides the fact that it's a structure type. If you want the type to be opaque, this can be a good thing. If client code is going to be referring to the member n
by name, then it's not opaque; it's visibly a structure, and in my opinion it makes sense to refer to it as a structure. But plenty of smart programmers disagree with me on this point. Be prepared to read and understand code written either way.)
(C++ has different rules. Given a declaration of struct blah
, you can refer to the type as just blah
, even without a typedef. Using a typedef might make your C code a little more C++-like -- if you think that's a good thing.)
Yes, there is a way. Two in fact. In October 2013 jshint added a way to ignore blocks of code like this:
// Code here will be linted with JSHint.
/* jshint ignore:start */
// Code here will be ignored by JSHint.
/* jshint ignore:end */
// Code here will be linted with JSHint.
You can also ignore a single line with a trailing comment like this:
ignoreThis(); // jshint ignore:line
I was looking for an answer to this myself. S3 appears to only support redirects, you can't just rewrite the URL and silently return a different resource. I'm considering using my build script to simply make copies of my index.html in all of the required path locations. Maybe that will work for you too.
setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").
From the command line, you can type
python setup.py --help
...to get a list of commands. What you are looking to do is...
python setup.py install
Like most explanations I've seen, the ones above are clear about how to work with 2's complement, but don't really explain what they are mathematically. I'll try to do that, for integers at least, and I'll cover some background that's probably familiar first.
Recall how it works for decimal:
2345
is a way of writing
2 × 103 + 3 × 102 + 4 × 101 + 5 × 100.
In the same way, binary is a way of writing numbers using just 0 and 1 following the same general idea, but replacing those 10s above with 2s. Then in binary,
1111
is a way of writing
1 × 23 + 1 × 22 + 1 × 21 + 1 × 20
and if you work it out, that turns out to equal 15 (base 10). That's because it is
8+4+2+1 = 15.
This is all well and good for positive numbers. It even works for negative numbers if you're willing to just stick a minus sign in front of them, as humans do with decimal numbers. That can even be done in computers, sort of, but I haven't seen such a computer since the early 1970's. I'll leave the reasons for a different discussion.
For computers it turns out to be more efficient to use a complement representation for negative numbers. And here's something that is often overlooked. Complement notations involve some kind of reversal of the digits of the number, even the implied zeroes that come before a normal positive number. That's awkward, because the question arises: all of them? That could be an infinite number of digits to be considered.
Fortunately, computers don't represent infinities. Numbers are constrained to a particular length (or width, if you prefer). So let's return to positive binary numbers, but with a particular size. I'll use 8 digits ("bits") for these examples. So our binary number would really be
00001111
or
0 × 27 + 0 × 26 + 0 × 25 + 0 × 24 + 1 × 23 + 1 × 22 + 1 × 21 + 1 × 20
To form the 2's complement negative, we first complement all the (binary) digits to form
11110000
and add 1 to form
11110001
but how are we to understand that to mean -15?
The answer is that we change the meaning of the high-order bit (the leftmost one). This bit will be a 1 for all negative numbers. The change will be to change the sign of its contribution to the value of the number it appears in. So now our 11110001 is understood to represent
-1 × 27 + 1 × 26 + 1 × 25 + 1 × 24 + 0 × 23 + 0 × 22 + 0 × 21 + 1 × 20
Notice that "-" in front of that expression? It means that the sign bit carries the weight -27, that is -128 (base 10). All the other positions retain the same weight they had in unsigned binary numbers.
Working out our -15, it is
-128 + 64 + 32 + 16 + 1
Try it on your calculator. it's -15.
Of the three main ways that I've seen negative numbers represented in computers, 2's complement wins hands down for convenience in general use. It has an oddity, though. Since it's binary, there have to be an even number of possible bit combinations. Each positive number can be paired with its negative, but there's only one zero. Negating a zero gets you zero. So there's one more combination, the number with 1 in the sign bit and 0 everywhere else. The corresponding positive number would not fit in the number of bits being used.
What's even more odd about this number is that if you try to form its positive by complementing and adding one, you get the same negative number back. It seems natural that zero would do this, but this is unexpected and not at all the behavior we're used to because computers aside, we generally think of an unlimited supply of digits, not this fixed-length arithmetic.
This is like the tip of an iceberg of oddities. There's more lying in wait below the surface, but that's enough for this discussion. You could probably find more if you research "overflow" for fixed-point arithmetic. If you really want to get into it, you might also research "modular arithmetic".
Alternatively, create a figure()
object using the figsize
argument and then use add_subplot
to add your subplots. E.g.
import matplotlib.pyplot as plt
import numpy as np
f = plt.figure(figsize=(10,3))
ax = f.add_subplot(121)
ax2 = f.add_subplot(122)
x = np.linspace(0,4,1000)
ax.plot(x, np.sin(x))
ax2.plot(x, np.cos(x), 'r:')
Benefits of this method are that the syntax is closer to calls of subplot()
instead of subplots()
. E.g. subplots doesn't seem to support using a GridSpec
for controlling the spacing of the subplots, but both subplot()
and add_subplot()
do.
You literally just pass them in std::thread(func1,a,b,c,d);
that should have compiled if the objects existed, but it is wrong for another reason. Since there is no object created you cannot join or detach the thread and the program will not work correctly. Since it is a temporary the destructor is immediately called, since the thread is not joined or detached yet std::terminate
is called. You could std::join
or std::detach
it before the temp is destroyed, like std::thread(func1,a,b,c,d).join();//or detach
.
This is how it should be done.
std::thread t(func1,a,b,c,d);
t.join();
You could also detach the thread, read-up on threads if you don't know the difference between joining and detaching.
I think apache provides a better util class which provides a function to get the string
ReflectionToStringBuilder.toString(object)
If you don't want to type, you can create the statements with this:
USE Databasename
SELECT 'DROP TABLE [' + name + '];'
FROM sys.tables
Then copy and paste into a new SSMS window to run it.
most simple answer
<a onclick="window.open(this.href,'_blank');return false;" href="http://www.foracure.org.au">Some Other Site</a>
it will work
PsSuspend, as mentioned by Vadzim, even suspends/resumes a process by its name, not only by pid.
I use both PsSuspend and PsList (another tool from the PsTools suite) in a simple toggle script for the OneDrive process: if I need more bandwidth, I suspend the OneDrive sync, afterwards I resume the process by issuing the same mini script:
PsList -d onedrive|find/i "suspend" && PsSuspend -r onedrive || PsSuspend onedrive
PsSuspend command line utility from SysInternals
suite. It suspends / resumes a process by its id.
inline-styles
in a document have the highest priority, so for example say if you want to change the color of a div
element to blue
, but you've an inline style
with a color
property set to red
<div style="font-size: 18px; color: red;">
Hello World, How Can I Change The Color To Blue?
</div>
div {
color: blue;
/* This Won't Work, As Inline Styles Have Color Red And As
Inline Styles Have Highest Priority, We Cannot Over Ride
The Color Using An Element Selector */
}
So, Should I Use jQuery/Javascript? - Answer Is NO
We can use element-attr
CSS Selector with !important
, note, !important
is important here, else it won't over ride the inline styles..
<div style="font-size: 30px; color: red;">
This is a test to see whether the inline styles can be over ridden with CSS?
</div>
div[style] {
font-size: 12px !important;
color: blue !important;
}
Note: Using
!important
ONLY will work here, but I've useddiv[style]
selector to specifically selectdiv
havingstyle
attribute
Here are some demo & short cuts if you uses GitHub, the basic ideas are the same.
1. Open terminal like this
2. Paste the below command to terminal followed by a space and then paste the path of the .xcuserstate file simply like this
3. Make sure you have the correct git ignore and then commit the code :)

To list the largest directories from the current directory in human readable format:
du -sh * | sort -hr
A better way to restrict number of rows can be
du -sh * | sort -hr | head -n10
Where you can increase the suffix of -n
flag to restrict the number of rows listed
Sample:
[~]$ du -sh * | sort -hr

REST security is transport dependent while SOAP security is not.
REST inherits security measures from the underlying transport while SOAP defines its own via WS-Security.
When we talk about REST, over HTTP - all security measures applied HTTP are inherited and this is known as transport level security.
Transport level security, secures your message only while its on the wire - as soon as it leaves the wire, the message is no more secured.
But, with WS-Security, its message level security - even though the message leaves the transport channel it will be still protected. Also - with message level security you can partly encrypt the message [not the entire message, but only the parts you want] - but with transport level security you can't do it.
WS-Security has measures for authentication, integrity, confidentiality and non-repudiation while SSL doesn't support non repudiation [with 2-legged OAuth it does].
In performance-wise SSL is very much faster than WS-Security.

SELECT *
FROM table
WHERE id = (SELECT MAX(id) FROM TABLE)
Document has already explain the usage. So I am using SQL to explain these methods
Assuming there is an Order (orders)
has many OrderItem (order_items)
.
And you have already build the relationship between them.
// App\Models\Order:
public function orderItems() {
return $this->hasMany('App\Models\OrderItem', 'order_id', 'id');
}
These three methods are all based on a relationship.
Result: with()
return the model object and its related results.
Advantage: It is eager-loading which can prevent the N+1 problem.
When you are using the following Eloquent Builder:
Order::with('orderItems')->get();
Laravel change this code to only two SQL:
// get all orders:
SELECT * FROM orders;
// get the order_items based on the orders' id above
SELECT * FROM order_items WHERE order_items.order_id IN (1,2,3,4...);
And then laravel merge the results of the second SQL as different from the results of the first SQL by foreign key. At last return the collection results.
So if you selected columns without the foreign_key in closure, the relationship result will be empty:
Order::with(['orderItems' => function($query) {
// $query->sum('quantity');
$query->select('quantity'); // without `order_id`

select * from `order_items` where `order`.`id` = `order_item`.`order_id`
)
whereHas
and orWhereHas

I know it's malapropos, but IMHO easy way is:
def insert (source_str, insert_str, pos):
return source_str[:pos]+insert_str+source_str[pos:]
This work-around worked for me: http://connect.microsoft.com/PowerShell/feedback/details/419466/new-webserviceproxy-needs-force-parameter-to-ignore-ssl-errors
Basically, in your PowerShell script:
add-type @"

using System.Security.Cryptography.X509Certificates;
public class TrustAllCertsPolicy : ICertificatePolicy {
public bool CheckValidationResult(
ServicePoint srvPoint, X509Certificate certificate,
WebRequest request, int certificateProblem) {
return true;
}
}
"@
[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy
$result = Invoke-WebRequest -Uri "https://IpAddress/resource"
I encountered this issue not with a real device, but with an emulator. I fixed it by running react-native start in the terminal before trying to run the code with android studio. I never encountered this issue when running react-native run-android in the terminal.
First off, your trigger as you already see is going to update every record in the table. There is no filtering done to accomplish jus the rows changed.
Secondly, you're assuming that only one row changes in the batch which is incorrect as multiple rows could change.
The way to do this properly is to use the virtual inserted and deleted tables: http://msdn.microsoft.com/en-us/library/ms191300.aspx
quick answer
#include<stdio.h>
#include<time.h>
int main()
{
clock_t t1, t2;
t1 = clock();
int i;
for(i = 0; i < 1000000; i++)
{
int x = 90;
}
t2 = clock();
float diff = ((float)(t2 - t1) / 1000000.0F ) * 1000;
printf("%f",diff);
return 0;
}
This is not something you can do in a foolproof way. One possibility would be to examine every character in the file to ensure that it doesn't contain any characters in the ranges 0x00 - 0x1f
or 0x7f -0x9f
but, as I said, this may be true for any number of files, including at least one other variant of ISO8859.
Another possibility is to look for specific words in the file in all of the languages supported and see if you can find them.
So, for example, find the equivalent of the English "and", "but", "to", "of" and so on in all the supported languages of 8859-1 and see if they have a large number of occurrences within the file.
I'm not talking about literal translation such as:
English French
------- ------
of de, du
and et
the le, la, les
although that's possible. I'm talking about common words in the target language (for all I know, Icelandic has no word for "and" - you'd probably have to use their word for "fish" [sorry that's a little stereotypical, I didn't mean any offense, just illustrating a point]).
We can do this using data() method. C++11 provides this method.
#include<bits/stdc++.h>
using namespace std;
int main()
{
ios::sync_with_stdio(false);
vector<int>v = {7, 8, 9, 10, 11};
int *arr = v.data();
for(int i=0; i<v.size(); i++)
{
cout<<arr[i]<<" ";
}
return 0;
}
Define my string in a properties file?
Multiline strings aren't allowed in properties files. You can use \n in properties files, but I don't think that is much of a solution in your case.
If the first character is an integer, it will not capitalize the first letter.
>>> '2s'.capitalize()
'2s'
If you want the functionality, strip off the digits, you can use '2'.isdigit()
to check for each character.
>>> s = '123sa'
>>> for i, c in enumerate(s):
... if not c.isdigit():
... break
...
>>> s[:i] + s[i:].capitalize()
'123Sa'
As of SQL Server 2016 you have
DROP TABLE IF EXISTS [foo];
If you are trying to push your code direct to the master branch then use command
git push origin master
It helps me.
With the following code, you can simulate a click on the 'close' button of the dialog (change the string 'MY_DIALOG' for the name of your own dialog)
$("div[aria-labelledby='ui-dialog-title-MY_DIALOG'] div.ui-helper-clearfix a.ui-dialog-titlebar-close")[0].click();
groupByKey:
Syntax:
sparkContext.textFile("hdfs://")
.flatMap(line => line.split(" ") )
.map(word => (word,1))
.groupByKey()
.map((x,y) => (x,sum(y)))
groupByKey can cause out of disk problems as data is sent over the network and collected on the reduce workers.
reduceByKey:
Syntax:
sparkContext.textFile("hdfs://")
.flatMap(line => line.split(" "))
.map(word => (word,1))
.reduceByKey((x,y)=> (x+y))
Data are combined at each partition, only one output for one key at each partition to send over the network. reduceByKey required combining all your values into another value with the exact same type.
aggregateByKey:
same as reduceByKey, which takes an initial value.
3 parameters as input i. initial value ii. Combiner logic iii. sequence op logic
Example:
val keysWithValuesList = Array("foo=A", "foo=A", "foo=A", "foo=A", "foo=B", "bar=C", "bar=D", "bar=D")
val data = sc.parallelize(keysWithValuesList)
//Create key value pairs
val kv = data.map(_.split("=")).map(v => (v(0), v(1))).cache()
val initialCount = 0;
val addToCounts = (n: Int, v: String) => n + 1
val sumPartitionCounts = (p1: Int, p2: Int) => p1 + p2
val countByKey = kv.aggregateByKey(initialCount)(addToCounts, sumPartitionCounts)
ouput: Aggregate By Key sum Results bar -> 3 foo -> 5
combineByKey:
3 parameters as input
Example:
val result = rdd.combineByKey(
(v) => (v,1),
( (acc:(Int,Int),v) => acc._1 +v , acc._2 +1 ) ,
( acc1:(Int,Int),acc2:(Int,Int) => (acc1._1+acc2._1) , (acc1._2+acc2._2))
).map( { case (k,v) => (k,v._1/v._2.toDouble) })
result.collect.foreach(println)
reduceByKey,aggregateByKey,combineByKey preferred over groupByKey
Reference: Avoid groupByKey

You can add a callback function to your DatePicker to tell it to blur the input field before showing the DatePicker.
$('.selector').datepicker({

According to Google's Machine Learning Glossary, an epoch is defined as
"A full training pass over the entire dataset such that each example has been seen once. Thus, an epoch represents N/batch_size
training iterations, where N is the total number of examples."
If you are training model for 10 epochs with batch size 6, given total 12 samples that means:
the model will be able to see whole dataset in 2 iterations ( 12 / 6 = 2) i.e. single epoch.
overall, the model will have 2 X 10 = 20 iterations (iterations-per-epoch X no-of-epochs)
re-evaluation of loss and model parameters will be performed after each iteration!

Given that the Apache Subversion server will be moved to this new DNS alias: sub.someaddress.com.tr
:
With Subversion 1.7 or higher, use svn relocate
. Relocate is used when the SVN server's location changes. switch
is only used if you want to change your local working copy to another branch or another path. If using TortoiseSVN, you may follow instructions from the TortoiseSVN Manual. If using the SVN command line interface, refer to this section of SVN's documentation. The command should look like this:
svn relocate svn://sub.someaddress.com.tr/project
Keep using /project
given that the actual contents of your repository probably won't change.
Note: svn relocate
is not available before version 1.7 (thanks to ColinM for the info). In older versions you would use:
svn switch --relocate OLD NEW
int[]
and int*
are represented the same way, except int[] allocates (IIRC).
ap
is a pointer, therefore giving it the value of an integer is dangerous, as you have no idea what's at address 45.
when you try to access it (x = *ap
), you try to access address 45, which causes the crash, as it probably is not a part of the memory you can access.
Here is a simple letter-range implementation:
Code
def letter_range(start, stop="{", step=1):
"""Yield a range of lowercase letters."""
for ord_ in range(ord(start.lower()), ord(stop.lower()), step):
yield chr(ord_)
Demo
list(letter_range("a", "f"))
# ['a', 'b', 'c', 'd', 'e']
list(letter_range("a", "f", step=2))
# ['a', 'c', 'e']
Try this one with #Input field

The usual way to use assertRaises
is to call a function:
self.assertRaises(TypeError, test_function, args)
to test that the function call test_function(args) raises a TypeError.
The problem with self.testListNone[:1]
is that Python evaluates the expression immediately, before the assertRaises
method is called. The whole reason why test_function
and args
is passed as separate arguments to self.assertRaises
is to allow assertRaises
to call test_function(args)
from within a try...except
block, allowing assertRaises
to catch the exception.
Since you've defined self.testListNone = None
, and you need a function to call, you might use operator.itemgetter like this:
import operator
self.assertRaises(TypeError, operator.itemgetter, (self.testListNone,slice(None,1)))
since
operator.itemgetter(self.testListNone,slice(None,1))
is a long-winded way of saying self.testListNone[:1]
, but which separates the function (operator.itemgetter
) from the arguments.
m2e is only included in the Java developer version of Eclipse, as you can see on this page ("Maven" topic): http://www.eclipse.org/downloads/compare.php
However, an easy way to get m2e is through the Eclipse Marketplace:
Go to Help -> Eclipse Marketplace and look for m2e. Click "Maven Integration for Eclipse", then on Install (or drag and drop the install link to your running Eclipse workspace if you opened the marketplace in a browser), et voila!
Direct browser access: http://marketplace.eclipse.org/content/maven-integration-eclipse
You should do ex.StackTrace instead of ex.ToString()
Instead of merge, as others suggested, you can rebase one branch onto another:
git checkout BranchB
git rebase BranchA
This takes BranchB
and rebases it onto BranchA
, which effectively looks like BranchB
was branched from BranchA
, not master
.
