proxy_pass http://IP:8080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-for $remote_addr;
port_in_redirect off;

}
error_page 500 502 503 504 /50x.html;

}
}
You could try this solution :
In your location
block when you use proxy_pass
do something like this:
location ... {
add_header yourHeaderName yourValue;
proxy_pass xxxx://xxx_my_proxy_addr_xxx;
# Now use this solution:
proxy_ignore_headers yourHeaderName // but set by proxy
# Or if above didn't work maybe this:
proxy_hide_header yourHeaderName // but set by proxy
}
I'm not sure would it be exactly what you need but try some manipulation of this method and maybe result will fit your problem.
Also you can use this combination:
proxy_hide_header headerSetByProxy;
set $sent_http_header_set_by_proxy yourValue;
Increasing the timeout will not likely solve your issue since, as you say, the actual target web server is responding just fine.
I had this same issue and I found it had to do with not using a keep-alive on the connection. I can't actually answer why this is but, in clearing the connection header I solved this issue and the request was proxied just fine:
server {
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_pass http://localhost:5000;
}
}
Have a look at this posts which explains it in more detail: nginx close upstream connection after request Keep-alive header clarification http://nginx.org/en/docs/http/ngx_http_upstream_module.html#keepalive
If you are using Apache reverse proxy for serving an app running on a localhost port you must add a location to your vhost.
<Location />
ProxyPass http://localhost:1339/ retry=0
ProxyPassReverse http://localhost:1339/
ProxyPreserveHost On
ProxyErrorOverride Off
</Location>
To get the IP address have following options
console.log(">>>", req.ip);// this works fine for me returned a valid ip address
console.log(">>>", req.headers['x-forwarded-for'] );// returned a valid IP address
console.log(">>>", req.headers['X-Real-IP'] ); // did not work returned undefined
console.log(">>>", req.connection.remoteAddress );// returned the loopback IP address
So either use req.ip or req.headers['x-forwarded-for']
If you have ruby on your system, how about a small Ruby Proxy using Sinatra (make sure to install the Sinatra Gem). This should be easier than setting up apache. The code can be found here.
Later versions of dataTables
have the following language
settings (taken from here):
"infoEmpty"
- displayed when there are no records in the table"zeroRecords"
- displayed when there no records matching the filteringe.g.
$('#example').DataTable( {
"language": {
"infoEmpty": "No records available - Got it?",
}
});
Note: As the property names do not contain any special characters you can remove the quotes:
$('#example').DataTable( {
language: {
infoEmpty: "No records available - Got it?",
}
});
I had this error because I included the requirejs file along with other librairies included directly in a script tag. Those librairies (like lodash) used a define function that was conflicting with require's define. The requirejs file was loading asynchronously so I suspect that the require's define was defined after the other libraries define, hence the conflict.
To get rid of the error, include all your other js files by using requirejs.

OAuth v2 specs indicates:
Access token attributes and the methods used to access protected resources are beyond the scope of this specification and are defined by companion specifications.
My Authorisation Server has a webservice (SOAP) endpoint that allows the Resource Server to know whether the access_token is valid.
In case you want to:
then:
from operator import itemgetter
foo = {'foo':1,'zip':2,'zam':3,'bar':4}
keys = ("foo","bar")
getter = itemgetter(*keys) # returns all values
try:
values = getter(foo)
except KeyError:
# not both keys exist
pass
You can use the non-standard FROM clause.
UPDATE b
SET column1 = a.column1,
column2 = a.column2,
column3 = a.column3
FROM a
WHERE a.id = b.id
AND b.id = 1
If you want all the li tags in an array even when they are in different ul tags then you can simply do
var lis = document.getElementByTagName('li');
and if you want to get particular div tag li's then:
var lis = document.getElementById('divID').getElementByTagName('li');
else if you want to search a ul first and then its li tags then you can do:
var uls = document.getElementsByTagName('ul');
for(var i=0;i<uls.length;i++){
var lis=uls[i].getElementsByTagName('li');
for(var j=0;j<lis.length;j++){
console.log(lis[j].innerHTML);
}
}
Also , in PHPMyAdmin , you can select table from left side(list of tables) then do this by going there.
Operations Tab->Table Options->AUTO_INCREMENT.
Now, Set your values and then press Go under the Table Options Box.
Using pyautogui
To install
pip install pyautogui
and to find the location of the mouse pointer
import pyautogui
print(pyautogui.position())
This will give the pixel location to which mouse pointer is at.
After setting the path of your jdk use JPS

You do this in 3 different ways:
Before you do an INSERT
, always issue a BEGIN;
statement. This will turn off autocommits. You will need to do a COMMIT;
once you want your data to be persisted in the database.
Use autocommit=0;
every time you instantiate a database connection.
For a global setting, add a autocommit=0
variable in your my.cnf
configuration file in MySQL.
With C#9 came the Relational Pattern Matching. This allows us to do:
switch (value)
{
case 1 or 2 or 3:
// Do stuff
break;
case 4 or 5 or 6:
// Do stuff
break;
default:
// Do stuff
break;
}

Pattern-matching changes for C# 9.0
Relational patterns permit the programmer to express that an input value must satisfy a relational constraint when compared to a constant value

This post might be old , but this is the solution which worked for me .
There are two ways to resize an image. The new size can be specified:
Manually;
height, width = src.shape[:2]
dst = cv2.resize(src, (2*width, 2*height), interpolation = cv2.INTER_CUBIC)
By a scaling factor.
dst = cv2.resize(src, None, fx = 2, fy = 2, interpolation = cv2.INTER_CUBIC)
,
where fx is the scaling factor along the horizontal axis and fy along the vertical axis.
To shrink an image, it will generally look best with INTER_AREA interpolation, whereas to enlarge an image, it will generally look best with INTER_CUBIC (slow) or INTER_LINEAR (faster but still looks OK).
import cv2
img = cv2.imread('YOUR_PATH_TO_IMG')
height, width = img.shape[:2]
max_height = 300
max_width = 300
# only shrink if img is bigger than required
if max_height < height or max_width < width:
# get scaling factor
scaling_factor = max_height / float(height)
if max_width/float(width) < scaling_factor:
scaling_factor = max_width / float(width)
# resize image
img = cv2.resize(img, None, fx=scaling_factor, fy=scaling_factor, interpolation=cv2.INTER_AREA)
cv2.imshow("Shrinked image", img)
key = cv2.waitKey()
import cv2 as cv
im = cv.imread(path)
height, width = im.shape[:2]
thumbnail = cv.resize(im, (round(width / 10), round(height / 10)), interpolation=cv.INTER_AREA)
cv.imshow('exampleshq', thumbnail)
cv.waitKey(0)
cv.destroyAllWindows()

.The simple command 'keytool' also works on Windows and/or with Cygwin.
IF you're using Cygwin here is the modified command that I used from the bottom of "S.Botha's" answer :
Execute the keytool command from inside it, where you provide the path to your new Cert at the end, like so:
./keytool.exe -import -trustcacerts -keystore ../lib/security/cacerts -storepass changeit -noprompt -alias myownaliasformysystem -file "D:\Stuff\saved-certs\ca.cert"
Notice, because if this is under Cygwin you're giving a path to a non-Cygwin program, so the path is DOS-like and in quotes.
This works for me on the webpack.config.js
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
'window.jQuery': 'jquery'
}),
in another javascript or into HTML add:
global.jQuery = require('jquery');
In the interface, you specify the property:
public interface IResourcePolicy
{
string Version { get; set; }
}
In the implementing class, you need to implement it:
public class ResourcePolicy : IResourcePolicy
{
public string Version { get; set; }
}
This looks similar, but it is something completely different. In the interface, there is no code. You just specify that there is a property with a getter and a setter, whatever they will do.
In the class, you actually implement them. The shortest way to do this is using this { get; set; }
syntax. The compiler will create a field and generate the getter and setter implementation for it.
why you don't do the opposite :
fruitdict = {
'apple':1,
'banana':'f',
'carrot':3,
}
locals().update(fruitdict)
Update :
don't use the code above check the comment.
by the way why you don't mark the vars that you want to get i don't know maybe like this:
# All the vars that i want to get are followed by _fruit
apple_fruit = 1
carrot_fruit = 'f'
for var in locals():
if var.endswith('fruit'):
you_dict.update({var:locals()[var])
The universal solution is using the HTML tag <sup>
, as suggested in the main answer.
However, the idea behind Markdown is precisely to avoid the use of such tags:
The document should look nice as plain text, not only when rendered.
Another answer proposes using Unicode characters, which makes the document look nice as a plain text document but could reduce compatibility.
Finally, I would like to remember the simplest solution for some documents: the character ^
.
Some Markdown implementation (e.g. MacDown in macOS) interprets the caret as an instruction for superscript.
Ex.
Sin^2 + Cos^2 = 1
Clearly, Stack Overflow does not interpret the caret as a superscript instruction. However, the text is comprehensible, and this is what really matters when using Markdown.
In C/C++ programming there are two types of strings: the C strings and the standard strings. With the <string>
header, we can use the standard strings. On the other hand, the C strings are just an array of normal chars. So, in order to convert a standard string to a C string, we use the c_str()
function.
for example
// a string to a C-style string conversion//
const char *cstr1 = str1.c_str();
cout<<"Operation: *cstr1 = str1.c_str()"<<endl;
cout<<"The C-style string c_str1 is: "<<cstr1<<endl;
cout<<"\nOperation: strlen(cstr1)"<<endl;
cout<<"The length of C-style string str1 = "<<strlen(cstr1)<<endl;
And the output will be,
Operation: *cstr1 = str1.c_str()
The C-style string c_str1 is: Testing the c_str
Operation: strlen(cstr1)
The length of C-style string str1 = 17

If you're using libraries that look up a large amount of configation behind-the-scenes, such as WCF, you might consider doing this:
AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", "MyWcfClientWrapper.dll.config");
Or in PowerShell:
[AppDomain]::CurrentDomain.SetData("APP_CONFIG_FILE", "MyWcfClientWrapper.dll.config")
IMO this technique is a code smell and is really only suitable for use in ad hoc scripting. If you find yourself wanting to do this in production code, maybe it's time for an architectural review.
The following is NOT recommended:
As a technical curiosity, here's a variation on the theme. You can create a static constructor inside one of the classes housed in the DLL, and make this call from there. I wouldn't recommend doing this except as a last resort.
Here is my implementation for your reference:
def _mkdir_recursive(self, path):
sub_path = os.path.dirname(path)
if not os.path.exists(sub_path):
self._mkdir_recursive(sub_path)
if not os.path.exists(path):
os.mkdir(path)
Hope this help!
This article can provide a lot of insight here: http://redis.io/topics/memory-optimization
There are many ways to store an array of Objects in Redis (spoiler: I like option 1 for most use cases):
Store the entire object as JSON-encoded string in a single key and keep track of all Objects using a set (or list, if more appropriate). For example:
INCR id:users
SET user:{id} '{"name":"Fred","age":25}'
SADD users {id}
Generally speaking, this is probably the best method in most cases. If there are a lot of fields in the Object, your Objects are not nested with other Objects, and you tend to only access a small subset of fields at a time, it might be better to go with option 2.
Advantages: considered a "good practice." Each Object is a full-blown Redis key. JSON parsing is fast, especially when you need to access many fields for this Object at once. Disadvantages: slower when you only need to access a single field.
Store each Object's properties in a Redis hash.
INCR id:users
HMSET user:{id} name "Fred" age 25
SADD users {id}
Advantages: considered a "good practice." Each Object is a full-blown Redis key. No need to parse JSON strings. Disadvantages: possibly slower when you need to access all/most of the fields in an Object. Also, nested Objects (Objects within Objects) cannot be easily stored.
Store each Object as a JSON string in a Redis hash.
INCR id:users
HMSET users {id} '{"name":"Fred","age":25}'
This allows you to consolidate a bit and only use two keys instead of lots of keys. The obvious disadvantage is that you can't set the TTL (and other stuff) on each user Object, since it is merely a field in the Redis hash and not a full-blown Redis key.
Advantages: JSON parsing is fast, especially when you need to access many fields for this Object at once. Less "polluting" of the main key namespace. Disadvantages: About same memory usage as #1 when you have a lot of Objects. Slower than #2 when you only need to access a single field. Probably not considered a "good practice."
Store each property of each Object in a dedicated key.
INCR id:users
SET user:{id}:name "Fred"
SET user:{id}:age 25
SADD users {id}
According to the article above, this option is almost never preferred (unless the property of the Object needs to have specific TTL or something).
Advantages: Object properties are full-blown Redis keys, which might not be overkill for your app. Disadvantages: slow, uses more memory, and not considered "best practice." Lots of polluting of the main key namespace.
Option 4 is generally not preferred. Options 1 and 2 are very similar, and they are both pretty common. I prefer option 1 (generally speaking) because it allows you to store more complicated Objects (with multiple layers of nesting, etc.) Option 3 is used when you really care about not polluting the main key namespace (i.e. you don't want there to be a lot of keys in your database and you don't care about things like TTL, key sharding, or whatever).
If I got something wrong here, please consider leaving a comment and allowing me to revise the answer before downvoting. Thanks! :)
Several of the answers on this page are 'single use' fixes to the described problem. Meaning, the next time you open a document with vim, the previous tab settings will return.
If anyone is interested in permanently changing the tab settings:
add the following lines: (more info here)
set tabstop=4 set shiftwidth=4 set expandtab
then save file and test
I have used this method with success to reduce the verbosity of the "org.apache.http" logs:
ch.qos.logback.classic.Logger logger = (ch.qos.logback.classic.Logger) LoggerFactory.getLogger("org.apache.http");
logger.setLevel(Level.TRACE);
logger.setAdditive(false);
There is no way in the C++ language to check whether a variable is initialized or not (although class types with constructors will be initialized automatically).
Instead, what you need to do is provide constructor(s) that initialize your class to a valid state. Static code checkers (and possibly some compilers) can help you find missing variables in constructors. This way you don't have to worry about being in a bogus state and the if
checks in your method can go away completely.
man printf.1
has a note at the bottom: "...your shell may have its own version of printf
...". This question is tagged for bash
, but if at all possible, I try to write scripts portable to any shell. dash
is usually a good minimum baseline for portability - so the answer here works in bash
, dash
, & zsh
. If a script works in those 3, it's most likely portable to just about anywhere.
The latest implementation of printf
in dash
[1] doesn't colorize output given a %s
format specifier with an ANSI escape character \e
-- but, a format specifier %b
combined with octal \033
(equivalent to an ASCII ESC
) will get the job done. Please comment for any outliers, but AFAIK, all shells have implemented printf
to use the ASCII octal subset at a bare minimum.
To the title of the question "Using colors with printf", the most portable way to set formatting is to combine the %b
format specifier for printf
(as referenced in an earlier answer from @Vlad) with an octal escape \033
.
portable-color.sh
#/bin/sh
P="\033["
BLUE=34
printf "-> This is %s %-6s %s text \n" $P"1;"$BLUE"m" "blue" $P"0m"
printf "-> This is %b %-6s %b text \n" $P"1;"$BLUE"m" "blue" $P"0m"
Outputs:
$ ./portable-color.sh
-> This is \033[1;34m blue \033[0m text
-> This is blue text
...and 'blue' is blue in the second line.
The %-6s
format specifier from the OP is in the middle of the format string between the opening & closing control character sequences.
[1] Ref: man dash
Section "Builtins" :: "printf" :: "Format"
$timeFirst = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;
You will then be able to use the seconds to find minutes, hours, days, etc.
You are experiencing this issue for two reasons.
When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)
User.java
@Entity
@Table(name="user")
public class User {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="iduser")
private Long idUser;
@Column(name="user_name")
private String userName;
@OneToOne()
@JoinColumn(name="idarea")
private Area area;
public Long getIdUser() {
return idUser;
}
public void setIdUser(Long idUser) {
this.idUser = idUser;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Area getArea() {
return area;
}
public void setArea(Area area) {
this.area = area;
}
}
Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:
@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")
While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.
Area.java
@Entity
@Table(name = "area")
public class Area {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="idarea")
private Long idArea;
@Column(name="area_name")
private String areaName;
@OneToOne(fetch=FetchType.LAZY, mappedBy="area")
private User user;
public Long getIdArea() {
return idArea;
}
public void setIdArea(Long idArea) {
this.idArea = idArea;
}
public String getAreaName() {
return areaName;
}
public void setAreaName(String areaName) {
this.areaName = areaName;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
$recipients = "[email protected],[email protected],[email protected],[email protected]";
$email_array = explode(",",$recipients);

$headers = 'From: [email protected]' . "\r\n" .
'Reply-To: [email protected]' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);

When using JetBrains IDE's with Git, "stashing and unstashing actions are supported in addition to shelving and unshelving. These features have much in common; the major difference is in the way patches are generated and applied. Shelve can operate with either individual files or bunch of files, while Stash can only operate with a whole bunch of changed files at once. Here are some more details on the differences between them."
This enhances the accepted answer by decorating the $http service with an abort method as follows ...
'use strict';
angular.module('admin')
.config(["$provide", function ($provide) {
$provide.decorator('$http', ["$delegate", "$q", function ($delegate, $q) {
var getFn = $delegate.get;
var cancelerMap = {};
function getCancelerKey(method, url) {
var formattedMethod = method.toLowerCase();
var formattedUrl = encodeURI(url).toLowerCase().split("?")[0];
return formattedMethod + "~" + formattedUrl;
}
$delegate.get = function () {
var cancelerKey, canceler, method;
var args = [].slice.call(arguments);
var url = args[0];
var config = args[1] || {};
if (config.timeout == null) {
method = "GET";
cancelerKey = getCancelerKey(method, url);
canceler = $q.defer();
cancelerMap[cancelerKey] = canceler;
config.timeout = canceler.promise;
args[1] = config;
}
return getFn.apply(null, args);
};
$delegate.abort = function (request) {
console.log("aborting");
var cancelerKey, canceler;
cancelerKey = getCancelerKey(request.method, request.url);
canceler = cancelerMap[cancelerKey];
if (canceler != null) {
console.log("aborting", cancelerKey);
if (request.timeout != null && typeof request.timeout !== "number") {
canceler.resolve();
delete cancelerMap[cancelerKey];
}
}
};
return $delegate;
}]);
}]);
WHAT IS THIS CODE DOING?
To cancel a request a "promise" timeout must be set. If no timeout is set on the HTTP request then the code adds a "promise" timeout. (If a timeout is set already then nothing is changed).
However, to resolve the promise we need a handle on the "deferred". We thus use a map so we can retrieve the "deferred" later. When we call the abort method, the "deferred" is retrieved from the map and then we call the resolve method to cancel the http request.
Hope this helps someone.
LIMITATIONS
Currently this only works for $http.get but you can add code for $http.post and so on
HOW TO USE ...
You can then use it, for example, on state change, as follows ...
rootScope.$on('$stateChangeStart', function (event, toState, toParams) {
angular.forEach($http.pendingRequests, function (request) {
$http.abort(request);
});
});
Assuming you're looking to kill whatever is on port 3000 (which is what webrick normally uses), type this in your terminal to find out the PID of the process:
$ lsof -wni tcp:3000
Then, use the number in the PID column to kill the process:
$ kill -9 PID
Short of using a video camera, no.
Many youtube videos for demonstrating iPhone applications are made with a screen grabber application (such as iShowU, ScreenFlow, or Snapz Pro) and the simulator. Be aware that the speed of response in the simulator can be dramatically different than a device - so it's possible to get effects (and miss) with the simulator you'll never see on a device. In particular, default animations can flash by in the simulator, where they just look quick on a device.
Since <input>
element displays only value of value attribute, we have to manipulate only it:
<input type="submit" class="btn fa-input" value=" Input">
I'm using 
entity here, which corresponds to the U+F043, the Font Awesome's 'tint' symbol.
Then we have to style it to use the font:
.fa-input {
font-family: FontAwesome, 'Helvetica Neue', Helvetica, Arial, sans-serif;
}
Which will give us the tint symbol in Font Awesome and the other text in the appropriate font.
However, this control will not be pixel-perfect, so you might have to tweak it by yourself.
you can print it as string:
printf("%s\n", foo);
You could define controller at the <html>
level.
<html ng-app="app" ng-controller="titleCtrl">
<head>
<title>{{ Page.title() }}</title>
...
You create service: Page
and modify from controllers.
myModule.factory('Page', function() {
var title = 'default';
return {
title: function() { return title; },
setTitle: function(newTitle) { title = newTitle }
};
});
Inject Page
and Call 'Page.setTitle()' from controllers.

The primary role of the @Named annotation is to define a bean for the purpose of resolving EL statements within the application, usually through JSF EL resolvers. Injection can be performed using names but this was not how injection in CDI was meant to work since CDI gives us a much richer way to express injection points and the beans to be injected into them.

Using MS SQL Server 2012, you need to perform 3 basic steps:
First, generate .sql
file containing only the structure of the source DB
.sql
file locallySecond, replace the source DB with the destination one in the .sql
file
Finally, populate with data
Data Source=Mehdi\SQLEXPRESS;Initial Catalog=db_test;User ID=sa;Password=sqlrpwrd15
You are done.
sorry for the sudo code..I'm on a phone. ;)
between = (time < string2 && time > string1);
if (string1 > string2) between = !between;
if they are timestamps or strings this works. just change the variable names to match
Set the method attribute to POST because file content can't be put inside a URL parameter using a form.
Set the value of enctype to multipart/form-data because the data will be split into multiple parts, one for each file plus one for the text of the form body that may be sent with them.
Well, this is a terribly late answer but I think I'll still put my two cents in... I could have posted this as a comment because this answer doesn't essentially add any new solution but it does add value to the post as yet another alternative. But in a comment I wouldn't be able to give all the details because of character limit.
NOTE: This needs an edit to bootstrap CSS file - move style definitions for .badge
above .label-default
. Couldn't find any practical side effects due to the change in my limited testing.
While broc.seib's solution is probably the best way to achieve the requirement of OP with minimal addition to CSS, it is possible to achieve the same effect without any extra CSS at all just like Jens A. Koch's solution or by using .label-xxx
contextual classes because they are easy to remember compared to progress-bar-xxx
classes. I don't think that .alert-xxx
classes give the same effect.
All you have to do is just use .badge
and .label-xxx
classes together (but in this order). Don't forget to make the changes mentioned in NOTE above.
<a href="#">Inbox <span class="badge label-warning">42</span></a>
looks like this:
IMPORTANT: This solution may break your styles if you decide to upgrade and forget to make the changes in your new local CSS file. My solution for this challenge was to copy all .label-xxx
styles in my custom CSS file and load it after all other CSS files. This approach also helps when I use a CDN for loading BS3.
**P.S: ** Both the top rated answers have their pros and cons. It's just the way you prefer to do your CSS because there is no "only correct way" to do it.
I don't know about JSON.NET, but it works fine with JavaScriptSerializer
from System.Web.Extensions.dll
(.NET 3.5 SP1):
using System.Collections.Generic;
using System.Web.Script.Serialization;
public class NameTypePair
{
public string OBJECT_NAME { get; set; }
public string OBJECT_TYPE { get; set; }
}
public enum PositionType { none, point }
public class Ref
{
public int id { get; set; }
}
public class SubObject
{
public NameTypePair attributes { get; set; }
public Position position { get; set; }
}
public class Position
{
public int x { get; set; }
public int y { get; set; }
}
public class Foo
{
public Foo() { objects = new List<SubObject>(); }
public string displayFieldName { get; set; }
public NameTypePair fieldAliases { get; set; }
public PositionType positionType { get; set; }
public Ref reference { get; set; }
public List<SubObject> objects { get; set; }
}
static class Program
{
const string json = @"{
""displayFieldName"" : ""OBJECT_NAME"",

Edit:
Json.NET works using the same JSON and classes.
Foo foo = JsonConvert.DeserializeObject<Foo>(json);
tk.mainloop()
blocks. It means that execution of your Python commands halts there. You can see that by writing:
while 1:
ball.draw()
tk.mainloop()
print("hello") #NEW CODE
time.sleep(0.01)
You will never see the output from the print statement. Because there is no loop, the ball doesn't move.
On the other hand, the methods update_idletasks()
and update()
here:
while True:
ball.draw()
tk.update_idletasks()
tk.update()
...do not block; after those methods finish, execution will continue, so the while
loop will execute over and over, which makes the ball move.
An infinite loop containing the method calls update_idletasks()
and update()
can act as a substitute for calling tk.mainloop()
. Note that the whole while loop can be said to block just like tk.mainloop()
because nothing after the while loop will execute.
However, tk.mainloop()
is not a substitute for just the lines:
tk.update_idletasks()
tk.update()
Rather, tk.mainloop()
is a substitute for the whole while loop:
while True:
tk.update_idletasks()
tk.update()
Response to comment:
Here is what the tcl docs say:
Update idletasks
This subcommand of update flushes all currently-scheduled idle events from Tcl's event queue. Idle events are used to postpone processing until “there is nothing else to do”, with the typical use case for them being Tk's redrawing and geometry recalculations. By postponing these until Tk is idle, expensive redraw operations are not done until everything from a cluster of events (e.g., button release, change of current window, etc.) are processed at the script level. This makes Tk seem much faster, but if you're in the middle of doing some long running processing, it can also mean that no idle events are processed for a long time. By calling update idletasks, redraws due to internal changes of state are processed immediately. (Redraws due to system events, e.g., being deiconified by the user, need a full update to be processed.)
APN As described in Update considered harmful, use of update to handle redraws not handled by update idletasks has many issues. Joe English in a comp.lang.tcl posting describes an alternative:
So update_idletasks()
causes some subset of events to be processed that update()
causes to be processed.
From the update docs:
update ?idletasks?
The update command is used to bring the application “up to date” by entering the Tcl event loop repeatedly until all pending events (including idle callbacks) have been processed.
If the idletasks keyword is specified as an argument to the command, then no new events or errors are processed; only idle callbacks are invoked. This causes operations that are normally deferred, such as display updates and window layout calculations, to be performed immediately.
KBK (12 February 2000) -- My personal opinion is that the [update] command is not one of the best practices, and a programmer is well advised to avoid it. I have seldom if ever seen a use of [update] that could not be more effectively programmed by another means, generally appropriate use of event callbacks. By the way, this caution applies to all the Tcl commands (vwait and tkwait are the other common culprits) that enter the event loop recursively, with the exception of using a single [vwait] at global level to launch the event loop inside a shell that doesn't launch it automatically.
The commonest purposes for which I've seen [update] recommended are:
- Keeping the GUI alive while some long-running calculation is executing. See Countdown program for an alternative. 2) Waiting for a window to be configured before doing things like geometry management on it. The alternative is to bind on events such as that notify the process of a window's geometry. See Centering a window for an alternative.
What's wrong with update? There are several answers. First, it tends to complicate the code of the surrounding GUI. If you work the exercises in the Countdown program, you'll get a feel for how much easier it can be when each event is processed on its own callback. Second, it's a source of insidious bugs. The general problem is that executing [update] has nearly unconstrained side effects; on return from [update], a script can easily discover that the rug has been pulled out from under it. There's further discussion of this phenomenon over at Update considered harmful.
.....
Is there any chance I can make my program work without the while loop?
Yes, but things get a little tricky. You might think something like the following would work:
class Ball:
def __init__(self, canvas, color):
self.canvas = canvas
self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
self.canvas.move(self.id, 245, 100)
def draw(self):
while True:
self.canvas.move(self.id, 0, -1)
ball = Ball(canvas, "red")
ball.draw()
tk.mainloop()
The problem is that ball.draw() will cause execution to enter an infinite loop in the draw() method, so tk.mainloop() will never execute, and your widgets will never display. In gui programming, infinite loops have to be avoided at all costs in order to keep the widgets responsive to user input, e.g. mouse clicks.
So, the question is: how do you execute something over and over again without actually creating an infinite loop? Tkinter has an answer for that problem: a widget's after()
method:
from Tkinter import *
import random
import time
tk = Tk()
tk.title = "Game"
tk.resizable(0,0)
tk.wm_attributes("-topmost", 1)
canvas = Canvas(tk, width=500, height=400, bd=0, highlightthickness=0)
canvas.pack()
class Ball:
def __init__(self, canvas, color):
self.canvas = canvas
self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
self.canvas.move(self.id, 245, 100)
def draw(self):
self.canvas.move(self.id, 0, -1)
self.canvas.after(1, self.draw) #(time_delay, method_to_execute)
ball = Ball(canvas, "red")
ball.draw() #Changed per Bryan Oakley's comment
tk.mainloop()
The after() method doesn't block (it actually creates another thread of execution), so execution continues on in your python program after after() is called, which means tk.mainloop() executes next, so your widgets get configured and displayed. The after() method also allows your widgets to remain responsive to other user input. Try running the following program, and then click your mouse on different spots on the canvas:
from Tkinter import *
import random
import time
root = Tk()
root.title = "Game"
root.resizable(0,0)
root.wm_attributes("-topmost", 1)
canvas = Canvas(root, width=500, height=400, bd=0, highlightthickness=0)
canvas.pack()
class Ball:
def __init__(self, canvas, color):
self.canvas = canvas
self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
self.canvas.move(self.id, 245, 100)
self.canvas.bind("<Button-1>", self.canvas_onclick)
self.text_id = self.canvas.create_text(300, 200, anchor='se')
self.canvas.itemconfig(self.text_id, text='hello')
def canvas_onclick(self, event):
self.canvas.itemconfig(
self.text_id,
text="You clicked at ({}, {})".format(event.x, event.y)
)
def draw(self):
self.canvas.move(self.id, 0, -1)
self.canvas.after(50, self.draw)
ball = Ball(canvas, "red")
ball.draw() #Changed per Bryan Oakley's comment.
root.mainloop()
final
adds an explicit intent to not have your function overridden, and will cause a compiler error should this be violated:
struct A {
virtual int foo(); // #1
};
struct B : A {
int foo();
};
As the code stands, it compiles, and B::foo
overrides A::foo
. B::foo
is also virtual, by the way. However, if we change #1 to virtual int foo() final
, then this is a compiler error, and we are not allowed to override A::foo
any further in derived classes.
Note that this does not allow us to "reopen" a new hierarchy, i.e. there's no way to make B::foo
a new, unrelated function that can be independently at the head of a new virtual hierarchy. Once a function is final, it can never be declared again in any derived class.
In my case since I had a jump host or Bastion host on the way, and because the signatures on these bastion nodes had changed since they were imported into known_hosts file, I just needed to delete those entries/lines from the following file:
/Users/a.abdi-kelishami/.ssh/known_hosts
From above file, delete those lines referring to the bastion hosts.
You can center auto width div using display:table;
div{
margin: 0px auto;
float: none;
display: table;
}
Reading all the comments by you, I think you are just trying to display it in a certain format rather than changing the value / casting it to int
.
I think the easiest way to display 12.00
as "12"
would be using string format specifiers.
double val = 12.00;
string displayed_value = val.ToString("N0"); // Output will be "12"
The best part about this solution is, that it will change 1200.00
to "1,200"
(add a comma to it) which is very useful to display amount/money/price of something.

The two answers are good. And I also suggest you a similar method:
<% @images.each.with_index do |page, index| %>
<% end %>
You might not see the difference between this and the accepted answer. Let me direct your eyes to these method calls: .each.with_index
see how it's .each
and then .with_index
.
My working solution is:
cd /opt/genymobile/genymotion/tools
./adb shell
You have to use its own adb tool.
You can add this code to your asp.net webapi project
in file Global.asax
protected void Application_BeginRequest()
{
string origin = Request.Headers.Get("Origin");
if (Request.HttpMethod == "OPTIONS")
{
Response.AddHeader("Access-Control-Allow-Origin", origin);
Response.AddHeader("Access-Control-Allow-Headers", "*");
Response.AddHeader("Access-Control-Allow-Methods", "GET,POST,PUT,OPTIONS,DELETE");
Response.StatusCode = 200;
Response.End();
}
else
{
Response.AddHeader("Access-Control-Allow-Origin", origin);
Response.AddHeader("Access-Control-Allow-Headers", "*");
Response.AddHeader("Access-Control-Allow-Methods", "GET,POST,PUT,OPTIONS,DELETE");
}
}
I have now got the steps needed to call procedure from C#
//GIVE PROCEDURE NAME
cmd = new OracleCommand("PROCEDURE_NAME", con);
cmd.CommandType = CommandType.StoredProcedure;
//ASSIGN PARAMETERS TO BE PASSED
cmd.Parameters.Add("PARAM1",OracleDbType.Varchar2).Value = VAL1;
cmd.Parameters.Add("PARAM2",OracleDbType.Varchar2).Value = VAL2;
//THIS PARAMETER MAY BE USED TO RETURN RESULT OF PROCEDURE CALL
cmd.Parameters.Add("vSUCCESS", OracleDbType.Varchar2, 1);
cmd.Parameters["vSUCCESS"].Direction = ParameterDirection.Output;
//USE THIS PARAMETER CASE CURSOR IS RETURNED FROM PROCEDURE
cmd.Parameters.Add("vCHASSIS_RESULT",OracleDbType.RefCursor,ParameterDirection.InputOutput);
//CALL PROCEDURE
con.Open();
OracleDataAdapter da = new OracleDataAdapter(cmd);
cmd.ExecuteNonQuery();
//RETURN VALUE
if (cmd.Parameters["vSUCCESS"].Value.ToString().Equals("T"))
{
//YOUR CODE
}
//OR
//IN CASE CURSOR IS TO BE USED, STORE IT IN DATATABLE
con.Open();
OracleDataAdapter da = new OracleDataAdapter(cmd);
da.Fill(dt);
Hope this helps
This version always returns the number of seconds difference as a positive number (same result as @freedeveloper's solution):

Facebook does not allow you to change the "What's on your mind?" text box, unless of course you're developing an application for use on Facebook.
You were correct to use WaitForSeconds. But I suspect that you tried using it without coroutines. That's how it should work:
public void SomeMethod()
{
StartCoroutine(SomeCoroutine());
}
private IEnumerator SomeCoroutine()
{
TextUI.text = "Welcome to Number Wizard!";
yield return new WaitForSeconds (3);
TextUI.text = ("The highest number you can pick is " + max);
yield return new WaitForSeconds (3);
TextUI.text = ("The lowest number you can pick is " + min);
}
lvalue
means "left value" -- it should be assignable. You cannot change the value of text
since it is an array, not a pointer.
Either declare it as char pointer (in this case it's better to declare it as const char*
):
const char *text;
if(number == 2)
text = "awesome";
else
text = "you fail";
Or use strcpy:
char text[60];
if(number == 2)
strcpy(text, "awesome");
else
strcpy(text, "you fail");
This works in many popular languages like JavaScript and Ruby, why not in Python?
>>> ['a', 'b', 'c'].join('')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'list' object has no attribute 'join'
Strange enough, in Python the join
method is on the str
class:
# this is the Python way
"".join(['a','b','c','d'])
Why join
is not a method in the list
object like in JavaScript or other popular script languages? It is one example of how the Python community thinks. Since join is returning a string, it should be placed in the string class, not on the list class, so the str.join(list)
method means: join the list into a new string using str
as a separator (in this case str
is an empty string).
Somehow I got to love this way of thinking after a while. I can complain about a lot of things in Python design, but not about its coherence.

I suppose send to template full request is little bit redundant. I do it this way
from django.shortcuts import render
def home(request):
app_url = request.path
return render(request, 'home.html', {'app_url': app_url})
##template
{{ app_url }}
1) PYTHONPATH
is an environment variable which you can set to add additional directories where python will look for modules and packages. e.g.:
# make python look in the foo subdirectory of your home directory for
# modules and packages
export PYTHONPATH=${PYTHONPATH}:${HOME}/foo
Here I use the sh
syntax. For other shells (e.g. csh
,tcsh
), the syntax would be slightly different. To make it permanent, set the variable in your shell's init file (usually ~/.bashrc).
2) Ubuntu comes with python already installed. There may be reasons for installing other (independent) python versions, but I've found that to be rarely necessary.
3) The folder where your modules live is dependent on PYTHONPATH
and where the directories were set up when python was installed. For the most part, the installed stuff you shouldn't care about where it lives -- Python knows where it is and it can find the modules. Sort of like issuing the command ls
-- where does ls
live? /usr/bin
? /bin
? 99% of the time, you don't need to care -- Just use ls
and be happy that it lives somewhere on your PATH
so the shell can find it.
4) I'm not sure I understand the question. 3rd party modules usually come with install instructions. If you follow the instructions, python should be able to find the module and you shouldn't have to care about where it got installed.
5) Configure PYTHONPATH
to include the directory where your module resides and python will be able to find your module.
Although hashcode does nothing with your business logic, we have to take care of it in most cases. Because when your object is put into a hash based container(HashSet
, HashMap
...), the container puts/gets the element's hashcode.
Just return an object literal

var dCodes = fg.codecsCodes.rs; // Linked ICDs
var dCodes2 = fg.codecsCodes2.rs; //Linked CPTs
return {
dCodes: dCodes,
dCodes2: dCodes2
};
}
var result = newCodes();
alert(result.dCodes);
alert(result.dCodes2);
Actually the purpose of np.meshgrid
is already mentioned in the documentation:
Return coordinate matrices from coordinate vectors.
Make N-D coordinate arrays for vectorized evaluations of N-D scalar/vector fields over N-D grids, given one-dimensional coordinate arrays x1, x2,..., xn.
So it's primary purpose is to create a coordinates matrices.
You probably just asked yourself:
The reason you need coordinate matrices with Python/NumPy is that there is no direct relation from coordinates to values, except when your coordinates start with zero and are purely positive integers. Then you can just use the indices of an array as the index. However when that's not the case you somehow need to store coordinates alongside your data. That's where grids come in.
Suppose your data is:
1 2 1
2 5 2
1 2 1
However, each value represents a 3 x 2 kilometer area (horizontal x vertical). Suppose your origin is the upper left corner and you want arrays that represent the distance you could use:
import numpy as np
h, v = np.meshgrid(np.arange(3)*3, np.arange(3)*2)
where v is:
array([[0, 0, 0],
[2, 2, 2],
[4, 4, 4]])
and h:
array([[0, 3, 6],
[0, 3, 6],
[0, 3, 6]])
So if you have two indices, let's say x
and y
(that's why the return value of meshgrid
is usually xx
or xs
instead of x
in this case I chose h
for horizontally!) then you can get the x coordinate of the point, the y coordinate of the point and the value at that point by using:
h[x, y] # horizontal coordinate
v[x, y] # vertical coordinate
data[x, y] # value
That makes it much easier to keep track of coordinates and (even more importantly) you can pass them to functions that need to know the coordinates.
However, np.meshgrid
itself isn't often used directly, mostly one just uses one of similar objects np.mgrid
or np.ogrid
.
Here np.mgrid
represents the sparse=False
and np.ogrid
the sparse=True
case (I refer to the sparse
argument of np.meshgrid
). Note that there is a significant difference between
np.meshgrid
and np.ogrid
and np.mgrid
: The first two returned values (if there are two or more) are reversed. Often this doesn't matter but you should give meaningful variable names depending on the context.
For example, in case of a 2D grid and matplotlib.pyplot.imshow
it makes sense to name the first returned item of np.meshgrid
x
and the second one y
while it's
the other way around for np.mgrid
and np.ogrid
.
np.ogrid
and sparse grids>>> import numpy as np
>>> yy, xx = np.ogrid[-5:6, -5:6]
>>> xx
array([[-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5]])
>>> yy
array([[-5],
[-4],
[-3],
[-2],
[-1],
[ 0],
[ 1],
[ 2],
[ 3],
[ 4],
[ 5]])
As already said the output is reversed when compared to np.meshgrid
, that's why I unpacked it as yy, xx
instead of xx, yy
:
>>> xx, yy = np.meshgrid(np.arange(-5, 6), np.arange(-5, 6), sparse=True)
>>> xx
array([[-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5]])
>>> yy
array([[-5],
[-4],
[-3],
[-2],
[-1],
[ 0],
[ 1],
[ 2],
[ 3],
[ 4],
[ 5]])
This already looks like coordinates, specifically the x and y lines for 2D plots.
Visualized:
yy, xx = np.ogrid[-5:6, -5:6]
plt.figure()
plt.title('ogrid (sparse meshgrid)')
plt.grid()
plt.xticks(xx.ravel())
plt.yticks(yy.ravel())
plt.scatter(xx, np.zeros_like(xx), color="blue", marker="*")
plt.scatter(np.zeros_like(yy), yy, color="red", marker="x")

[-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5],

The same applies here: The output is reversed compared to np.meshgrid
:

>>> xx

It's not only limited to 2D, these functions work for arbitrary dimensions (well, there is a maximum number of arguments given to function in Python and a maximum number of dimensions that NumPy allows):
>>> x1, x2, x3, x4 = np.ogrid[:3, 1:4, 2:5, 3:6]
>>> for i, x in enumerate([x1, x2, x3, x4]):
... print('x{}'.format(i+1))
... print(repr(x))
x1
array([[[[0]]],
[[[1]]],
[[[2]]]])
x2
array([[[[1]],
[[2]],
[[3]]]])
x3
array([[[[2],
[3],
[4]]]])
x4
array([[[[3, 4, 5]]]])
>>> # equivalent meshgrid output, note how the first two arguments are reversed and the unpacking
>>> x2, x1, x3, x4 = np.meshgrid(np.arange(1,4), np.arange(3), np.arange(2, 5), np.arange(3, 6), sparse=True)
>>> for i, x in enumerate([x1, x2, x3, x4]):
... print('x{}'.format(i+1))
... print(repr(x))
# Identical output so it's omitted here.
Even if these also work for 1D there are two (much more common) 1D grid creation functions:
Besides the start
and stop
argument it also supports the step
argument (even complex steps that represent the number of steps):
>>> x1, x2 = np.mgrid[1:10:2, 1:10:4j]
>>> x1 # The dimension with the explicit step width of 2
array([[1., 1., 1., 1.],
[3., 3., 3., 3.],
[5., 5., 5., 5.],
[7., 7., 7., 7.],
[9., 9., 9., 9.]])
>>> x2 # The dimension with the "number of steps"
array([[ 1., 4., 7., 10.],
[ 1., 4., 7., 10.],
[ 1., 4., 7., 10.],
[ 1., 4., 7., 10.],
[ 1., 4., 7., 10.]])
You specifically asked about the purpose and in fact, these grids are extremely useful if you need a coordinate system.
For example if you have a NumPy function that calculates the distance in two dimensions:
def distance_2d(x_point, y_point, x, y):
return np.hypot(x-x_point, y-y_point)
And you want to know the distance of each point:
>>> ys, xs = np.ogrid[-5:5, -5:5]
>>> distances = distance_2d(1, 2, xs, ys) # distance to point (1, 2)
>>> distances

The output would be identical if one passed in a dense grid instead of an open grid. NumPys broadcasting makes it possible!
Let's visualize the result:
plt.figure()
plt.title('distance to point (1, 2)')
plt.imshow(distances, origin='lower', interpolation="none")
plt.xticks(np.arange(xs.shape[1]), xs.ravel()) # need to set the ticks manually
plt.yticks(np.arange(ys.shape[0]), ys.ravel())
plt.colorbar()
And this is also when NumPys mgrid
and ogrid
become very convenient because it allows you to easily change the resolution of your grids:
ys, xs = np.ogrid[-5:5:200j, -5:5:200j]
# otherwise same code as above
However, since imshow
doesn't support x
and y
inputs one has to change the ticks by hand. It would be really convenient if it would accept the x
and y
coordinates, right?
It's easy to write functions with NumPy that deal naturally with grids. Furthermore, there are several functions in NumPy, SciPy, matplotlib that expect you to pass in the grid.
I like images so let's explore matplotlib.pyplot.contour
:
ys, xs = np.mgrid[-5:5:200j, -5:5:200j]
density = np.sin(ys)-np.cos(xs)
plt.figure()
plt.contour(xs, ys, density)
Note how the coordinates are already correctly set! That wouldn't be the case if you just passed in the density
.
Or to give another fun example using astropy models (this time I don't care much about the coordinates, I just use them to create some grid):
from astropy.modeling import models
z = np.zeros((100, 100))
y, x = np.mgrid[0:100, 0:100]
for _ in range(10):
g2d = models.Gaussian2D(amplitude=100,
x_mean=np.random.randint(0, 100),
y_mean=np.random.randint(0, 100),
x_stddev=3,
y_stddev=3)
z += g2d(x, y)
a2d = models.AiryDisk2D(amplitude=70,
x_0=np.random.randint(0, 100),
y_0=np.random.randint(0, 100),
radius=5)
z += a2d(x, y)
Although that's just "for the looks" several functions related to functional models and fitting (for example scipy.interpolate.interp2d
,
scipy.interpolate.griddata
even show examples using np.mgrid
) in Scipy, etc. require grids. Most of these work with open grids and dense grids, however some only work with one of them.
Finally I found A good css that works!!! Without position: absolute;
.
body {
display:table;
min-height: 100%;
}
.fixed-bottom {
display:table-footer-group;
}
I have been looking for this for a long time! Hope this helps.
The code finally used is the following from:
http://www.java2s.com/Code/Java/File-Input-Output/ConvertInputStreamtoString.htm
public static String convertStreamToString(InputStream is) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
reader.close();
return sb.toString();
}
public static String getStringFromFile (String filePath) throws Exception {
File fl = new File(filePath);
FileInputStream fin = new FileInputStream(fl);
String ret = convertStreamToString(fin);
//Make sure you close all streams.
fin.close();
return ret;
}
In the first situation, Num2
is extending the class Num
and since you are not redefining the special method named __init__()
in Num2
, it gets inherited from Num
.
When a class defines an
__init__()
method, class instantiation automatically invokes__init__()
for the newly-created class instance.
In the second situation, since you are redefining __init__()
in Num2
you need to explicitly call the one in the super class (Num
) if you want to extend its behavior.
class Num2(Num):
def __init__(self,num):
Num.__init__(self,num)
self.n2 = num*2
You can use the function connect_ex. It doesn't throw an exception. Instead of that, returns a C style integer value (referred to as errno in C):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = s.connect_ex((host, port))
s.close()
if result:
print "problem with socket!"
else:
print "everything it's ok!"
I think I've found a stupid workaround using =cell()
and a helper sheet. Thus avoiding custom functions and apps script.
=cell("address",[reference])
will provide you with a string reference (i.e. "$A$1") to the address of the cell referred to. Problem is it will not provide the sheet reference unless the cell is in a different sheet!
So:
where
This also works for named sheets. Then by all means adjust to work for your use case.
It's a good idea with generating these dates on the fly. However, I do not feel myself comfortable to do this with quite large range so I've ended up with the following solution:
CREATE TABLE DatesNumbers (
i MEDIUMINT NOT NULL,
PRIMARY KEY (i)
)
COMMENT='Used by Dates view'
;
INSERT INTO DatesNumbers
SELECT
a.i + (10 * b.i) + (100 * c.i) + (1000 * d.i) + (10000 * e.i) - 59999 AS i
FROM
(SELECT 0 AS i UNION ALL SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) AS a,
(SELECT 0 AS i UNION ALL SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) AS b,
(SELECT 0 AS i UNION ALL SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) AS c,
(SELECT 0 AS i UNION ALL SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) AS d,
(SELECT 0 AS i UNION ALL SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) AS e
;
SELECT
i,
CURRENT_DATE() + INTERVAL i DAY AS Date
FROM
DatesNumbers
That's it.
WHERE i < 0
or WHERE i > 0

The :has()
pseudo-selector is propsed in the CSS Selectors 4 spec, and will address this use case once implemented.
To use it, we will write something like:
.foo > .bar:has(> .baz) { /* style here */ }
In a structure like:
<div class="foo">
<div class="bar">
<div class="baz">Baz!</div>
</div>
</div>
This CSS will target the .bar
div - because it both has a parent .foo
and from its position in the DOM, > .baz
resolves to a valid element target.
Original Answer (left for historical purposes) - this portion is no longer accurate
For completeness, I wanted to point out that in the Selectors 4 specification (currently in proposal), this will become possible. Specifically, we will gain Subject Selectors, which will be used in the following format:
!div > span { /* style here */
The !
before the div
selector indicates that it is the element to be styled, rather than the span
. Unfortunately, no modern browsers (as of the time of this posting) have implemented this as part of their CSS support. There is, however, support via a JavaScript library called Sel, if you want to go down the path of exploration further.
If you want to search for documents that belong to a specific month, make sure to query like this:
// Anything greater than this month and less than the next month
db.posts.find({created_on: {$gte: new Date(2015, 6, 1), $lt: new Date(2015, 7, 1)}});
Avoid quering like below as much as possible.
// This may not find document with date as the last date of the month
db.posts.find({created_on: {$gte: new Date(2015, 6, 1), $lt: new Date(2015, 6, 30)}});
// don't do this too
db.posts.find({created_on: {$gte: new Date(2015, 6, 1), $lte: new Date(2015, 6, 30)}});
I was facing the same problem while trying to open images containing spaces and special characters like the following ´
So, after modifying the images names removing their spaces and special characters, everything worked perfectly.
ERROR! MySQL server PID file could not be found!
This might be due to issues with disk space, disk inode usage or innodb corruption which may lead to the error.
The issue was with the pid file and the solution was:
SSH login to server as a root
Create directory /var/run/mysql
mkdir /var/run/mysql
3) Create a file with name as mysqld.pid
touch mysqld.pid
Change its ownership and group to mysql:mysql
chown mysql:mysql mysqld.pid
Restart MySQL service
Done!
You should be able to use OrderBy
in LINQ...
var sortedItems = myList.OrderBy(s => s);
In similar situations, I've done well by putting something like the following into /etc/rc.local:
cd /path/to/my/script
./my_script.py &
cd -
echo `date +%Y-%b-%d_%H:%M:%S` > /tmp/ran_rc_local # check that rc.local ran
This has worked on multiple versions of Fedora and on Ubuntu 14.04 LTS, for both python and perl scripts.
you can use SemaphoreSlim to block the next thread that will try to execute that EF call.
static SemaphoreSlim semSlim = new SemaphoreSlim(1, 1);
await semSlim.WaitAsync();
try
{
// something like this here...
// EmployeeService.GetList(); or...
var result = await _ctx.Employees.ToListAsync();
}
finally
{
semSlim.Release();
}
This is the most simple solution for me:
$tStamp = Get-Date -format yyyy_MM_dd_HHmmss
$tStamp = Get-Date (get-date).AddMonths(6).Date -Format yyyyMMdd
You can use `
view.getLocationOnScreen(int[] location)
;` to get location of your view correctly.
But there is a catch if you use it before layout has been inflated you will get wrong position.
Solution to this problem is adding ViewTreeObserver
like this :-
Declare globally the array to store x y position of your view
int[] img_coordinates = new int[2];
and then add ViewTreeObserver
on your parent layout to get callback for layout inflation and only then fetch position of view otherwise you will get wrong x y coordinates
// set a global layout listener which will be called when the layout pass is completed and the view is drawn
parentViewGroup.getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener() {
public void onGlobalLayout() {
//Remove the listener before proceeding
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
parentViewGroup.getViewTreeObserver().removeOnGlobalLayoutListener(this);
} else {
parentViewGroup.getViewTreeObserver().removeGlobalOnLayoutListener(this);
}
// measure your views here
fab.getLocationOnScreen(img_coordinates);
}
}
);
and then use it like this
xposition = img_coordinates[0];
yposition = img_coordinates[1];
I could be wrong but I thought it used IE's proxy settings.
If it sees that you need to login it opens a dialog and asks you to do so (login that is).
Please see the description of this here -> http://docs.nuget.org/docs/release-notes/nuget-1.5
Agree with previous answers.
A little correction: There's a better way to print the decimal digits from left to right, without allocating extra buffer. In addition you may want to display a zero characeter if the score
is 0 (the loop suggested in the previous answers won't print anythng).
This demands an additional pass:
int div;
for (div = 1; div <= score; div *= 10)
;
do
{
div /= 10;
printf("%d\n", score / div);
score %= div;
} while (score);
With git show
you can get a similar result. For look the commit (like it looks on git log
view) with the list of files included in, use:
git show --name-only [commit-id_A]^..[commit-id_B]
Where [commit-id_A]
is the initial commit and [commit-id_B]
is the last commit than you want to show.
Special attention with ^
symbol. If you don't put that, the commit-id_A information will not deploy.

ClassPath is affected depending on what you provide. There are a couple of ways to set something on the classpath:
spark.driver.extraClassPath
or it's alias --driver-class-path
to set extra classpaths on the node running the driver.spark.executor.extraClassPath
to set extra class path on the Worker nodes.If you want a certain JAR to be effected on both the Master and the Worker, you have to specify these separately in BOTH flags.
Following the same rules as the JVM:
:
--conf "spark.driver.extraClassPath=/opt/prog/hadoop-aws-2.7.1.jar:/opt/prog/aws-java-sdk-1.10.50.jar"
;
--conf "spark.driver.extraClassPath=/opt/prog/hadoop-aws-2.7.1.jar;/opt/prog/aws-java-sdk-1.10.50.jar"
This depends on the mode which you're running your job under:
Client mode - Spark fires up a Netty HTTP server which distributes the files on start up for each of the worker nodes. You can see that when you start your Spark job:
16/05/08 17:29:12 INFO HttpFileServer: HTTP File server directory is /tmp/spark-48911afa-db63-4ffc-a298-015e8b96bc55/httpd-84ae312b-5863-4f4c-a1ea-537bfca2bc2b
16/05/08 17:29:12 INFO HttpServer: Starting HTTP Server
16/05/08 17:29:12 INFO Utils: Successfully started service 'HTTP file server' on port 58922.
16/05/08 17:29:12 INFO SparkContext: Added JAR /opt/foo.jar at http://***:58922/jars/com.mycode.jar with timestamp 1462728552732

Cluster mode - In cluster mode spark selected a leader Worker node to execute the Driver process on. This means the job isn't running directly from the Master node. Here, Spark will not set an HTTP server. You have to manually make your JARS available to all the worker node via HDFS/S3/Other sources which are available to all nodes.
In "Submitting Applications", the Spark documentation does a good job of explaining the accepted prefixes for files:
When using spark-submit, the application jar along with any jars included with the --jars option will be automatically transferred to the cluster. Spark uses the following URL scheme to allow different strategies for disseminating jars:
- file: - Absolute paths and file:/ URIs are served by the driver’s HTTP file server, and every executor pulls the file from the driver HTTP server.
- hdfs:, http:, https:, ftp: - these pull down files and JARs from the URI as expected
- local: - a URI starting with local:/ is expected to exist as a local file on each worker node. This means that no network IO will be incurred, and works well for large files/JARs that are pushed to each worker, or shared via NFS, GlusterFS, etc.
Note that JARs and files are copied to the working directory for each SparkContext on the executor nodes.
As noted, JARs are copied to the working directory for each Worker node. Where exactly is that? It is usually under /var/run/spark/work
, you'll see them like this:
drwxr-xr-x 3 spark spark 4096 May 15 06:16 app-20160515061614-0027
drwxr-xr-x 3 spark spark 4096 May 15 07:04 app-20160515070442-0028

drwxr-xr-x 3 spark spark 4096 May 18 17:20 app-20160518172045-0033
And when you look inside, you'll see all the JARs you deployed along:
[*@*]$ cd /var/run/spark/work/app-20160508173423-0014/1/
[*@*]$ ll

The most important thing to understand is priority. If you pass any property via code, it will take precedence over any option you specify via spark-submit
. This is mentioned in the Spark documentation:
Any values specified as flags or in the properties file will be passed on to the application and merged with those specified through SparkConf. Properties set directly on the SparkConf take highest precedence, then flags passed to spark-submit or spark-shell, then options in the spark-defaults.conf file
So make sure you set those values in the proper places, so you won't be surprised when one takes priority over the other.
Lets analyze each option in question:
--jars
vs SparkContext.addJar
: These are identical, only one is set through spark submit and one via code. Choose the one which suites you better. One important thing to note is that using either of these options does not add the JAR to your driver/executor classpath, you'll need to explicitly add them using the extraClassPath
config on both.SparkContext.addJar
vs SparkContext.addFile
: Use the former when you have a dependency that needs to be used with your code. Use the latter when you simply want to pass an arbitrary file around to your worker nodes, which isn't a run-time dependency in your code.--conf spark.driver.extraClassPath=...
or --driver-class-path
: These are aliases, doesn't matter which one you choose--conf spark.driver.extraLibraryPath=..., or --driver-library-path ...
Same as above, aliases.--conf spark.executor.extraClassPath=...
: Use this when you have a dependency which can't be included in an uber JAR (for example, because there are compile time conflicts between library versions) and which you need to load at runtime.--conf spark.executor.extraLibraryPath=...
This is passed as the java.library.path
option for the JVM. Use this when you need a library path visible to the JVM.Would it be safe to assume that for simplicity, I can add additional application jar files using the 3 main options at the same time:
You can safely assume this only for Client mode, not Cluster mode. As I've previously said. Also, the example you gave has some redundant arguments. For example, passing JARs to --driver-library-path
is useless, you need to pass them to extraClassPath
if you want them to be on your classpath. Ultimately, what you want to do when you deploy external JARs on both the driver and the worker is:
spark-submit --jars additional1.jar,additional2.jar \
--driver-class-path additional1.jar:additional2.jar \
--conf spark.executor.extraClassPath=additional1.jar:additional2.jar \
--class MyClass main-application.jar
A very simple method would be to use the extract
method to select all the digits. Simply supply it the regular expression '\d+'
which extracts any number of digits.
df['result'] = df.result.str.extract(r'(\d+)', expand=True).astype(int)
df
time result
1 09:00 52
2 10:00 62
3 11:00 44

The following is about plain C functions - in a C++ class the modifier 'static' has another meaning.
If you have just one file, this modifier makes absolutely no difference. The difference comes in bigger projects with multiple files:
In C, every "module" (a combination of sample.c and sample.h) is compiled independently and afterwards every of those compiled object files (sample.o) are linked together to an executable file by the linker.
Let's say you have several files that you include in your main file and two of them have a function that is only used internally for convenience called add(int a, b)
- the compiler would easily create object files for those two modules, but the linker will throw an error, because it finds two functions with the same name and it does not know which one it should use (even if there's nothing to link, because they aren't used somewhere else but in it's own file).
This is why you make this function, which is only used internal, a static function. In this case the compiler does not create the typical "you can link this thing"-flag for the linker, so that the linker does not see this function and will not generate an error.
The following will do.
string datestring = DateTime.Now.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
You can do this with Save Actions plugin Refer This article on how to configure the plugin.
Save Actions plugin Supports configurable, Eclipse like, save actions, including "optimize imports", "reformat code", "rearrange code", "compile file" and some quick fixes for Java like "add / remove 'this' qualifier", etc. The plugin executes the configured actions when the file is synchronised (or saved) on disk.
I prefer the hot-keys though, For Mac,
To format the code : Ctrl+Alt(Option)+L
And additionally I do,: Ctrl+Alt(Option)+O , This will remove unused imports and format the import list as well.
In addition to the answers already given, if you want to create a new directory, you could use this function:
def mkdir_p(mypath):
'''Creates a directory. equivalent to using mkdir -p on the command line'''
from errno import EEXIST
from os import makedirs,path
try:
makedirs(mypath)
except OSError as exc: # Python >2.5
if exc.errno == EEXIST and path.isdir(mypath):
pass
else: raise
and then:
import matplotlib
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(100))
# Create new directory
output_dir = "some/new/directory"
mkdir_p(output_dir)
fig.savefig('{}/graph.png'.format(output_dir))
According to this post this error message means:
Heap size is larger than your computer's physical memory.
Edit: Heap is not the only memory that is reserved, I suppose. At least there are other JVM settings like PermGenSpace that ask for the memory. With heap size 128M and a PermGenSpace of 64M you already fill the space available.
Why not downsize other memory settings to free up space for the heap?

A workaround is to use a willAnswer()
method.
For example the following works (and doesn't throw a MockitoException
but actually throws a checked Exception
as required here) using BDDMockito
:
given(someObj.someMethod(stringArg1)).willAnswer( invocation -> { throw new Exception("abc msg"); });
The equivalent for plain Mockito would to use the doAnswer
method
I use XAMPP and had the same error. I used Paul Gobée solution above and it worked for me. I navigated to C:\xampp\mysql\bin\mysqld-debug.exe
and upon starting the .exe
my Windows Firewall popped up asking for permission. Once I allowed it, it worked fine. I would have commented under his post but I do not have that much rep yet... sry! Just wanted to let everyone know this worked for me as well.
You can use a CASE
statement.
SELECT
CASE WHEN currate.currentrate IS NULL THEN 1 ELSE currate.currentrate END
FROM ...
If you want to use the default settings from http package, so you don't need to create a new Transport and Client object, you can change to ignore the certificate verification like this:
tr := http.DefaultTransport.(*http.Transport)
tr.TLSClientConfig.InsecureSkipVerify = true
What about a simple while loop?
while times > 0:
do_something()
times -= 1
You already have the variable; why not use it?

PARTITION BY
segregate sets, this enables you to be able to work(ROW_NUMBER(),COUNT(),SUM(),etc) on related set independently.
In your query, the related set comprised of rows with similar cdt.country_code, cdt.account, cdt.currency. When you partition on those columns and you apply ROW_NUMBER on them. Those other columns on those combination/set will receive sequential number from ROW_NUMBER
But that query is funny, if your partition by some unique data and you put a row_number on it, it will just produce same number. It's like you do an ORDER BY on a partition that is guaranteed to be unique. Example, think of GUID as unique combination of cdt.country_code, cdt.account, cdt.currency
newid()
produces GUID, so what shall you expect by this expression?
select
hi,ho,
row_number() over(partition by newid() order by hi,ho)
from tbl;
...Right, all the partitioned(none was partitioned, every row is partitioned in their own row) rows' row_numbers are all set to 1
Basically, you should partition on non-unique columns. ORDER BY on OVER needed the PARTITION BY to have a non-unique combination, otherwise all row_numbers will become 1
An example, this is your data:
create table tbl(hi varchar, ho varchar);
insert into tbl values
('A','X'),
('A','Y'),
('A','Z'),
('B','W'),
('B','W'),
('C','L'),
('C','L');
Then this is analogous to your query:
select
hi,ho,
row_number() over(partition by hi,ho order by hi,ho)
from tbl;
What will be the output of that?
HI HO COLUMN_2
A X 1
A Y 1
A Z 1
B W 1
B W 2
C L 1
C L 2
You see thee combination of HI HO? The first three rows has unique combination, hence they are set to 1, the B rows has same W, hence different ROW_NUMBERS, likewise with HI C rows.
Now, why is the ORDER BY
needed there? If the previous developer merely want to put a row_number on similar data (e.g. HI B, all data are B-W, B-W), he can just do this:
select
hi,ho,
row_number() over(partition by hi,ho)
from tbl;
But alas, Oracle(and Sql Server too) doesn't allow partition with no ORDER BY
; whereas in Postgresql, ORDER BY
on PARTITION is optional: http://www.sqlfiddle.com/#!1/27821/1
select
hi,ho,
row_number() over(partition by hi,ho)
from tbl;
Your ORDER BY
on your partition look a bit redundant, not because of the previous developer's fault, some database just don't allow PARTITION
with no ORDER BY
, he might not able find a good candidate column to sort on. If both PARTITION BY columns and ORDER BY columns are the same just remove the ORDER BY, but since some database don't allow it, you can just do this:
SELECT cdt.*,
ROW_NUMBER ()
OVER (PARTITION BY cdt.country_code, cdt.account, cdt.currency
ORDER BY newid())
seq_no
FROM CUSTOMER_DETAILS cdt
You cannot find a good column to use for sorting similar data? You might as well sort on random, the partitioned data have the same values anyway. You can use GUID for example(you use newid()
for SQL Server). So that has the same output made by previous developer, it's unfortunate that some database doesn't allow PARTITION
with no ORDER BY
Though really, it eludes me and I cannot find a good reason to put a number on the same combinations (B-W, B-W in example above). It's giving the impression of database having redundant data. Somehow reminded me of this: How to get one unique record from the same list of records from table? No Unique constraint in the table
It really looks arcane seeing a PARTITION BY with same combination of columns with ORDER BY, can not easily infer the code's intent.
Live test: http://www.sqlfiddle.com/#!3/27821/6
But as dbaseman have noticed also, it's useless to partition and order on same columns.
You have a set of data like this:
create table tbl(hi varchar, ho varchar);
insert into tbl values
('A','X'),
('A','X'),
('A','X'),
('B','Y'),
('B','Y'),
('C','Z'),
('C','Z');
Then you PARTITION BY hi,ho; and then you ORDER BY hi,ho. There's no sense numbering similar data :-) http://www.sqlfiddle.com/#!3/29ab8/3
select
hi,ho,
row_number() over(partition by hi,ho order by hi,ho) as nr
from tbl;
Output:
HI HO ROW_QUERY_A
A X 1
A X 2
A X 3
B Y 1
B Y 2
C Z 1
C Z 2
See? Why need to put row numbers on same combination? What you will analyze on triple A,X, on double B,Y, on double C,Z? :-)
You just need to use PARTITION on non-unique column, then you sort on non-unique column(s)'s unique-ing column. Example will make it more clear:
create table tbl(hi varchar, ho varchar);
insert into tbl values
('A','D'),
('A','E'),
('A','F'),
('B','F'),
('B','E'),
('C','E'),
('C','D');
select
hi,ho,
row_number() over(partition by hi order by ho) as nr
from tbl;
PARTITION BY hi
operates on non unique column, then on each partitioned column, you order on its unique column(ho), ORDER BY ho
Output:
HI HO NR
A D 1
A E 2
A F 3
B E 1
B F 2
C D 1
C E 2
That data set makes more sense
Live test: http://www.sqlfiddle.com/#!3/d0b44/1
And this is similar to your query with same columns on both PARTITION BY and ORDER BY:
select
hi,ho,
row_number() over(partition by hi,ho order by hi,ho) as nr
from tbl;
And this is the ouput:
HI HO NR
A D 1
A E 1
A F 1
B E 1
B F 1
C D 1
C E 1
See? no sense?
Live test: http://www.sqlfiddle.com/#!3/d0b44/3
Finally this might be the right query:
SELECT cdt.*,
ROW_NUMBER ()
OVER (PARTITION BY cdt.country_code, cdt.account -- removed: cdt.currency
ORDER BY
-- removed: cdt.country_code, cdt.account,
cdt.currency) -- keep
seq_no
FROM CUSTOMER_DETAILS cdt
Why not use this?

Answers above showing only how to set transparent background of TextView. We can achieve transparent Textview backcgorund in two way:
Second approach is better because it gives flexibility to set background with different color and then setting setting opacity to widget using android:alpha="0.2"
Example
<TextView
android:id="@+id/tv_name"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/black"
android:alpha="0.3"
android:textColor="@color/white"
android:textStyle="bold"/>

You can actually do what Chris Chalmers does in his answer, but you must make sure that HAML doesn't parse the JavaScript. This approach is actually useful when you need to use a different type than text/javascript
, which is was I needed to do for MathJax
.
You can use the plain
filter to keep HAML from parsing the script and throwing an illegal nesting error:
%script{type: "text/x-mathjax-config"}
:plain
MathJax.Hub.Config({
tex2jax: {
inlineMath: [["$","$"],["\\(","\\)"]]
}
});

You will probably find yourself using string.concat within the append parameter, but this is a very straightforward approach.

@parameter_1_Name = 'parameter_1_Value',
@parameter_2_name = 'parameter_2_value',
@parameter_z_name = 'parameter_z_value'

The clearest explanation for LSP I found so far has been "The Liskov Substitution Principle says that the object of a derived class should be able to replace an object of the base class without bringing any errors in the system or modifying the behavior of the base class" from here. The article gives code example for violating LSP and fixing it.
To handle this problem in a clean way, I suggest to use brew
and jenv
.
JAVA_VERSION=11
brew reinstall jenv
brew reinstall openjdk@${JAVA_VERSION}
jenv add /usr/local/opt/openjdk@${JAVA_VERSION}/
jenv global ${JAVA_VERSION}
~/.bashrc
or ~/.zshrc
export PATH="$HOME/.jenv/bin:$PATH"
eval "$(jenv init -)"
export JAVA_HOME="$HOME/.jenv/versions/`jenv version-name`"
Then restart your shell and try to execute java -version
Note: If you have this problem, your current JDK version is not existent or misconfigured (or may be you have only JRE).

We tend to get this message when we try to subscribe to a topic that has not been created yet. We generally rely on topics to be created a priori in our deployed environments, but we have component tests that run against a dockerized kafka instance, which starts clean every time.
In that case, we use AdminUtils in our test setup to check if the topic exists and create it if not. See this other stack overflow for more about setting up AdminUtils.
First of all, you have got the concept of hashing a little wrong and it had been rectified by Mr. Sanjay.
And yes, Java indeed implement a collision resolution technique. When two keys get hashed to a same value (as the internal array used is finite in size and at some point the hashcode() method will return same hash value for two different keys) at this time, a linked list is formed at the bucket location where all the informations are entered as an Map.Entry object that contains a key-value pair. Accessing an object via a key will at worst require O(n) if the entry in present in such a lists. Comparison between the key you passed with each key in such list will be done by the equals() method.
Although, from Java 8 , the linked lists are replaced with trees (O(log n))
Yes !!!! If I say Encapsulation is a kind of an advanced specific scope abstraction,
How many of you read/upvote my answer. Let's dig in why I am saying like this.
I need to clear two things before my claiming.
One is data hiding and, another one is the abstraction
I said, "Encapsulation is a kind of an advanced specific scope abstraction". Why? because we can see encapsulation as data hiding + abstraction
encapsulation = data hiding + abstraction
In encapsulation, we need to hide the data so outside person can not see the data and we need to provide methods that can be used to access the data. These methods may have validations or other features inside those things also hidden to an outside person. So here, we are hiding the implementation of access methods and it is called abstraction.
This is why I said like above encapsulation is a kind of abstraction.
So Where is the difference?
The difference is the abstraction is a general one if we are hiding something from the user for simplicity, maintainability and security and,
encapsulation is a specific one for which is related to internal states security where we are hiding the internal state (data hiding) and we are providing methods to access the data and those methods implementation also hidden from the outside person(abstraction).
For the basic (the current week's Sunday)

You could use the encodeURIComponent
to safely URL encode parts of a query string:

var url = 'http://example.com/?data=' + encodeURIComponent(array);

var array = JSON.stringify([ 'foo', 'bar' ]);
$.ajax({
url: 'http://example.com/',
type: 'GET',
data: { data: array },
success: function(result) {
// process the results
}
});
"success" : function(data){
//do stuff here
fnCallback(data);

If you got the error in your IDE(compile-time error), you need to add your mysql-connector jar file to your libs and add this to your referenced library of project too.
If you get this error when you are running it, then probably its because you have not included mysql-connector JAR file to your webserver's lib folder.
Add mysql-connector-java-5.1.25-bin.jar
to your classpath and also to your webserver's lib directory. Tomcat lib path is given as an example Tomcat 6.0\lib
This seems to be a common error. The solution is to:
Hope this helps in some cases.
The currently added directory is already committed in the repository. So delete the directory in the repository and commit the same directory again.
You can't set the precision of a double (or Double) to a specified number of decimal digits, because floating-point values don't have decimal digits. They have binary digits.
You will have to convert into a decimal radix, either via BigDecimal
or DecimalFormat
, depending on what you want to do with the value later.
See also my answer to this question for a refutation of the inevitable *100/100 answers.
My Solution :
db.collection("name of collection").find({}, {limit: 1}).sort({$natural: -1})
[Note: edited to modernize ggplot syntax]
Your example is not reproducible since there is no ex1221new
(there is an ex1221
in Sleuth2
, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot
. One advantage is that ggplot
works with data.frame
s directly.
You can set the labels with xlab()
and ylab()
, or make it part of the scale_*.*
call.
library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
xlab("My x label") +
ylab("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area("Nitrogen") +
scale_x_continuous("My x label") +
scale_y_continuous("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs
function
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
labs(size= "Nitrogen",
x = "My x label",
y = "My y label",
title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
which gives an identical figure to the one above.

In my case same error is there , I am using Asyanc / Await functions , for this needs to add AWAIT for findOne
Ex:const foundUser = User.findOne ({ "email" : req.body.email });
above , foundUser always contains Object value in both cases either user found or not because it's returning values before finishing findOne .
const foundUser = await User.findOne ({ "email" : req.body.email });
above , foundUser returns null if user is not there in collection with provided condition . If user found returns user document.
one time i found this script, this copy folder and files and keep the same structure of the source in the destination, you can make some tries with this.
# Find the source files
$sourceDir="X:\sourceFolder"
# Set the target file
$targetDir="Y:\Destfolder\"
Get-ChildItem $sourceDir -Include *.* -Recurse | foreach {
# Remove the original root folder
$split = $_.Fullname -split '\\'
$DestFile = $split[1..($split.Length - 1)] -join '\'
# Build the new destination file path
$DestFile = $targetDir+$DestFile
# Move-Item won't create the folder structure so we have to
# create a blank file and then overwrite it
$null = New-Item -Path $DestFile -Type File -Force
Move-Item -Path $_.FullName -Destination $DestFile -Force
}
For a non ASP.NET control, i.e. HTML controls like div, table, td, tr

reads the string before the space. it cannot read anything after it gets the first space.nextLine()
reads the whole line. Read until the end of the line or "/n".

You have to add the two modified files to the index before git will recognize it as a move.
The only difference between mv old new
and git mv old new
is that the git mv also adds the files to the index.
mv old new
then git add -A
would have worked, too.
Note that you can't just use git add .
because that doesn't add removals to the index.
Option 1 :
org.apache.commons.lang3.LocaleUtils.toLocale("en_US")
Option 2 :

For ease of use, ctypes is the way to go.
The following example of ctypes is from actual code I've written (in Python 2.5). This has been, by far, the easiest way I've found for doing what you ask.
import ctypes
# Load DLL into memory.
hllDll = ctypes.WinDLL ("c:\\PComm\\ehlapi32.dll")
# Set up prototype and parameters for the desired function call.
# HLLAPI
hllApiProto = ctypes.WINFUNCTYPE (
ctypes.c_int, # Return type.
ctypes.c_void_p, # Parameters 1 ...
ctypes.c_void_p,
ctypes.c_void_p,
ctypes.c_void_p) # ... thru 4.
hllApiParams = (1, "p1", 0), (1, "p2", 0), (1, "p3",0), (1, "p4",0),
# Actually map the call ("HLLAPI(...)") to a Python name.
hllApi = hllApiProto (("HLLAPI", hllDll), hllApiParams)
# This is how you can actually call the DLL function.
# Set up the variables and call the Python name with them.
p1 = ctypes.c_int (1)
p2 = ctypes.c_char_p (sessionVar)
p3 = ctypes.c_int (1)
p4 = ctypes.c_int (0)
hllApi (ctypes.byref (p1), p2, ctypes.byref (p3), ctypes.byref (p4))
The ctypes
stuff has all the C-type data types (int
, char
, short
, void*
, and so on) and can pass by value or reference. It can also return specific data types although my example doesn't do that (the HLL API returns values by modifying a variable passed by reference).
In terms of the specific example shown above, IBM's EHLLAPI is a fairly consistent interface.
All calls pass four void pointers (EHLLAPI sends the return code back through the fourth parameter, a pointer to an int
so, while I specify int
as the return type, I can safely ignore it) as per IBM's documentation here. In other words, the C variant of the function would be:
int hllApi (void *p1, void *p2, void *p3, void *p4)
This makes for a single, simple ctypes
function able to do anything the EHLLAPI library provides, but it's likely that other libraries will need a separate ctypes
function set up per library function.
The return value from WINFUNCTYPE
is a function prototype but you still have to set up more parameter information (over and above the types). Each tuple in hllApiParams
has a parameter "direction" (1 = input, 2 = output and so on), a parameter name and a default value - see the ctypes
doco for details
Once you have the prototype and parameter information, you can create a Python "callable" hllApi
with which to call the function. You simply create the needed variable (p1
through p4
in my case) and call the function with them.
There is a command
svn revert -R .
OR
you can use the --depth=infinity, which is actually same as above:
svn revert --depth=infinity
svn revert
is inherently dangerous, since its entire purpose is to throw away data—namely, your uncommitted changes. Once you've reverted, Subversion provides no way to get back those uncommitted changes
You can assign int
to char
directly.
int a = 65;
char c = a;
printf("%c", c);
In fact this will also work.
printf("%c", a); // assuming a is in valid range
I my case, I solved this issue going to the Publish tab in the project properties and then select the Application Files button. Then just:
Note: Before you apply this solution, make sure that you have already (as I did), checked all your solution's projects and found no references to stdole.dll assembly.
1 - Located stdole.dll file;
2 - Changed its Publish status to Exclude
3 - After that you need to republish your application.
This issue happened on a Visual Studio 2012, after its migration from Visual Studio 2010.
Hope it helps.

I have had a similar scenario where I needed to set the focus on a text box within a panel when the panel was shown. The panel was loaded on application startup, so I couldn't set the focus in the constructor. As the panel wasn't being loaded or being given focus on show, this meant that I had no event to fire the focus request from.
To solve this, I added a global method to my main that called a method in the panel that invoked requestFocusInWindow()
on the text area. I put the call to the global method in the button that showed the panel, after the call to show. This meant that the panel would be shown and then the text area assigned the focus after showing the panel. Hope that makes sense and helps!
Also, you can edit most of the auto-generated code by right clicking on the object in design view and selecting customize code, however I don't think that it allows you to edit panels.

I had the ValueError: zlib is required unless explicitly disabled using --disable-zlib
but upgrading pip from 7.x to 8.y resolved the problem.
So I would try to update tools before anything else.
That can be done using:
pip install --upgrade pip
Exact same thing, just omit the -c
option. Apache's docs on it here.
htpasswd /etc/apache2/.htpasswd newuser
Also, htpasswd
typically isn't run as root. It's typically owned by either the web server, or the owner of the files being served. If you're using root to edit it instead of logging in as one of those users, that's acceptable (I suppose), but you'll want to be careful to make sure you don't accidentally create a file as root (and thus have root own it and no one else be able to edit it).
Years passed and nowadays you can do it natively
(new TextEncoder().encode('foo')).length
Note that it's not supported by IE (you may use a polyfill for that).
Check the below links:
Implicit Wait
- It instructs the web driver to wait for some time by poll the DOM. Once you declared implicit wait it will be available for the entire life of web driver instance. By default the value will be 0. If you set a longer default, then the behavior will poll the DOM on a periodic basis depending on the browser/driver implementation.
Explicit Wait
+ ExpectedConditions
- It is the custom one. It will be used if we want the execution to wait for some time until some condition achieved.

I've created my own formatting utility. Which is extremely fast at processing the formatting along with giving you many features :)
It supports:
The code can be found here. You call it like this:
public static void main(String[])
{
int settings = ValueFormat.COMMAS | ValueFormat.PRECISION(2) | ValueFormat.MILLIONS;
String formatted = ValueFormat.format(1234567, settings);
}
I should also point out this doesn't handle decimal support, but is very useful for integer values. The above example would show "1.23M" as the output. I could probably add decimal support maybe, but didn't see too much use for it since then I might as well merge this into a BigInteger type of class that handles compressed char[] arrays for math computations.
Has anyone considered using int.Parse()
and int.TryParse()
like this
int bar = int.Parse(foo.ToString());
Even better like this
int bar;
if (!int.TryParse(foo.ToString(), out bar))
{
//Do something to correct the problem
}
It's a lot safer and less error prone
In my case, I've created a wrapper JS file in which I have the logic to select the correct variables according to my environment, dynamically.
I have these two functions, one it's a wrapper of a simple dotenv functionality, and the other discriminate between environments and set the result to the process.env object.
setEnvVariablesByEnvironment : ()=>{_x000D_
return new Promise((resolve)=>{_x000D_
_x000D_
if (process.env.NODE_ENV === undefined || process.env.NODE_ENV ==='development'){_x000D_
logger.info('Lower / Development environment was detected');_x000D_
_x000D_
environmentManager.getEnvironmentFromEnvFile()_x000D_
.then(envFile => {_x000D_
resolve(envFile);_x000D_
});_x000D_
_x000D_
}else{_x000D_
logger.warn('Production or Stage environment was detected.');_x000D_

log: 'Returned environment variables placed in .env file.'_x000D_
});_x000D_
}_x000D_
_x000D_
_x000D_
});_x000D_
} ,_x000D_
_x000D_
/*_x000D_

getEnvironmentFromEnvFile: () => {_x000D_
return new Promise((resolve)=>{_x000D_
logger.info('Trying to get configuration of environment variables from .env file');_x000D_
_x000D_
env.config({_x000D_

So, in my server.js file i only added the reference:
const envManager = require('./lib/application/config/environment/environment-manager');
And in my entry-point (server.js), it's just simple as use it.
envManager.setEnvVariablesByEnvironment()
.then(envVariables=>{
process.env= envVariables.payload;
const port = process.env.PORT_EXPOSE;
microService.listen(port, '0.0.0.0' , () =>{
let welcomeMessage = `Micro Service started at ${Date.now()}`;
logger.info(welcomeMessage);
logger.info(`${configuration.about.name} port configured -> : ${port}`);
logger.info(`App Author: ${configuration.about.owner}`);
logger.info(`App Version: ${configuration.about.version}`);
logger.info(`Created by: ${configuration.about.author}`);
});
});

May be little late ..but here is how you can do it recursively
public int sumAllDigits(int number) {
int sum = number % 10;
if(number/10 < 10){
return sum + number/10;
}else{
return sum + sumAllDigits(number/10);
}
If you want to format a date like JavaScript's (new Date()).toISOString()
for some reason, this is how you can do it in PHP:
$now = microtime(true);
gmdate('Y-m-d\TH:i:s', $now).sprintf('.%03dZ',round(($now-floor($now))*1000));
Sample output:
2016-04-27T18:25:56.696Z
Just to prove that subtracting off the whole number doesn't reduce the accuracy of the decimal portion:
>>> number_format(123.01234567890123456789,25)
=> "123.0123456789012408307826263"
>>> number_format(123.01234567890123456789-123,25)
=> "0.0123456789012408307826263"
PHP did round the decimal places, but it rounded them the same way in both cases.
Tags and Elements are not the same.
Elements
They are the pieces themselves, i.e. a paragraph is an element, or a header is an element, even the body is an element. Most elements can contain other elements, as the body element would contain header elements, paragraph elements, in fact pretty much all of the visible elements of the DOM.
Eg:
<p>This is the <span>Home</span> page</p>
Tags
Tags are not the elements themselves, rather they're the bits of text you use to tell the computer where an element begins and ends. When you 'mark up' a document, you generally don't want those extra notes that are not really part of the text to be presented to the reader. HTML borrows a technique from another language, SGML, to provide an easy way for a computer to determine which parts are "MarkUp" and which parts are the content. By using '<' and '>' as a kind of parentheses, HTML can indicate the beginning and end of a tag, i.e. the presence of '<' tells the browser 'this next bit is markup, pay attention'.
The browser sees the letters '
' and decides 'A new paragraph is starting, I'd better start a new line and maybe indent it'. Then when it sees '
' it knows that the paragraph it was working on is finished, so it should break the line there before going on to whatever is next.- Opening tag.
- Closing tagJust searched for the docs, and found this:
Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:
{# returns true #}
{{ 1 in [1, 2, 3] }}
{{ 'cd' in 'abcde' }}
Please use the attributes from the System.Web.Http namespace on your WebAPI actions:
[System.Web.Http.AcceptVerbs("GET", "POST")]
[System.Web.Http.HttpGet]
public string Auth(string username, string password)
{...}
The reason why it doesn't work is because you were using the attributes that are from the MVC namespace System.Web.Mvc
. The classes in the System.Web.Http
namespace are for WebAPI.
For a bit more flexibility than with micronyks answer, you can do it like that:
1. In your template, add #myIdentifier
to the element you want to obtain the width from. Example:
<p #myIdentifier>
my-component works!
</p>
2. In your controller, you can use this with @ViewChild('myIdentifier')
to get the width:
import {AfterViewInit, Component, ElementRef, OnInit, ViewChild} from '@angular/core';
@Component({
selector: 'app-my-component',
templateUrl: './my-component.component.html',
styleUrls: ['./my-component.component.scss']
})
export class MyComponentComponent implements AfterViewInit {
constructor() { }
ngAfterViewInit() {
console.log(this.myIdentifier.nativeElement.offsetWidth);
}
@ViewChild('myIdentifier')
myIdentifier: ElementRef;
}
Security
About the security risk with ElementRef
, like this, there is none. There would be a risk, if you would modify the DOM using an ElementRef. But here you are only getting DOM Elements so there is no risk. A risky example of using ElementRef
would be: this.myIdentifier.nativeElement.onclick = someFunctionDefinedBySomeUser;
. Like this Angular doesn't get a chance to use its sanitisation mechanisms since someFunctionDefinedBySomeUser
is inserted directly into the DOM, skipping the Angular sanitisation.
An md5 encryption is one of the worst, because you have to turn the code and it is already decrypted. I would recommend you the SHA256. I'm programming a bit longer and have had a good experience. Below would also be an encryption.

I've found that the stuff SQL Server gives you to do fuzzy matching is pretty clunky. I've had really good luck with my own CLR functions using the Levenshtein distance algorithm and some weighting. Using that algorithm, I've then made a UDF called GetSimilarityScore that takes two strings and returns a score between 0.0 and 1.0. The closer to 1.0 the match is, the better. Then, query with a threshold of >=0.8 or so to get the most likely matches. Something like this:
if object_id('tempdb..#similar') is not null drop table #similar
select a.id, (
select top 1 x.id
from MyTable x
where x.id <> a.id
order by dbo.GetSimilarityScore(a.MyField, x.MyField) desc
) as MostSimilarId
into #similar
from MyTable a
select *, dbo.GetSimilarityScore(a.MyField, c.MyField)
from MyTable a
join #similar b on a.id = b.id
join MyTable c on b.MostSimilarId = c.id
Just don't do it with really large tables. It's a slow process.
Here's the CLR UDFs:

Change the file to be executable by running:
chmod ugo+x ./awk-script
and you can then call your AWK script like this:
`$ echo "something" | ./awk-script`
Be careful of what you want to convert. JPG doesn't support alpha-transparency while PNG does. You will lose that information.
To convert, you may use the following function:
// Quality is a number between 0 (best compression) and 100 (best quality)
function png2jpg($originalFile, $outputFile, $quality) {
$image = imagecreatefrompng($originalFile);
imagejpeg($image, $outputFile, $quality);
imagedestroy($image);
}
This function uses the imagecreatefrompng()
and the imagejpeg()
functions from the GD library.
To concatenate strings in python you use the "+" sign
It doesn't exist at first. You have to create it in your home folder, /Users/usename/.m2/
(or ~/.m2
)
For example :
This is what helped me. My navigation bar is in the body tag. Entire code for navigation bar is in nav.html
file (without any html or body tag, only the code for navigation bar). In the target page, this goes in the head
tag:
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
Then in the body tag, a container is made with an unique id and a javascript block to load the nav.html
into the container, as follows:
<!--Navigation bar-->
<div id="nav-placeholder">
</div>
<script>
$(function(){
$("#nav-placeholder").load("nav.html");
});
</script>
<!--end of Navigation bar-->
you can pass it this way :
Url.Action("CreatePerson", "Person", new RouteValueDictionary(new { id = id }));
OR can also pass this way
Url.Action("CreatePerson", "Person", new { id = id });
Here's my "teach a person to fish" answer:
Rsync's syntax is definitely non-intuitive, but it is worth understanding.
-vvv
to see the debug info for rsync.$ rsync -nr -vvv --include="**/file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/
[sender] hiding directory 1280000000 because of pattern *
[sender] hiding directory 1260000000 because of pattern *
[sender] hiding directory 1270000000 because of pattern *
The key concept here is that rsync applies the include/exclude patterns for each directory recursively. As soon as the first include/exclude is matched, the processing stops.
The first directory it evaluates is /Storage/uploads
. Storage/uploads
has 1280000000/, 1260000000/, 1270000000/
dirs/files. None of them match file_11*.jpg
to include. All of them match *
to exclude. So they are excluded, and rsync ends.
*/
) first. Then the first dir component will be 1260000000/, 1270000000/, 1280000000/
since they match */
. The next dir component will be 1260000000/
. In 1260000000/
, file_11_00.jpg
matches --include="file_11*.jpg"
, so it is included. And so forth.$ rsync -nrv --include='*/' --include="file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/

The JSON.stringify
method supported by many modern browsers (including IE8) can output a beautified JSON string:
JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4); // stringify with 4 spaces at each level
Demo: http://jsfiddle.net/AndyE/HZPVL/
This method is also included with json2.js, for supporting older browsers.
If you don't need to do it programmatically, Try JSON Lint. Not only will it prettify your JSON, it will validate it at the same time.
In fact I would not use any REDIM, nor a loop for transferring data from sheet to array:
dim arOne()
arOne = range("A2:F1000")
or even
arOne = range("A2").CurrentRegion
and that's it, your array is filled much faster then with a loop, no redim.
System.Interactive provides Buffer()
for this purpose. Some quick testing shows performance is similar to Sam's solution.
Generics
can be defined using Wrapper
classes only. If you don't want to define using Wrapper types, you may use the Raw definition as below
@SuppressWarnings("rawtypes")
public HashMap buildMap(String letters)
{
HashMap checkSum = new HashMap();
for ( int i = 0; i < letters.length(); ++i )
{
checkSum.put(letters.charAt(i), primes[i]);
}
return checkSum;
}
Or define the HashMap using wrapper types, and store the primitive types. The primitive values will be promoted to their wrapper types.
public HashMap<Character, Integer> buildMap(String letters)
{
HashMap<Character, Integer> checkSum = new HashMap<Character, Integer>();
for ( int i = 0; i < letters.length(); ++i )
{
checkSum.put(letters.charAt(i), primes[i]);
}
return checkSum;
}
If you use Wordpress you can just use the wordpress build in function with the video id provided wp_get_attachment_metadata($videoID):
wp_get_attachment_metadata($videoID);
helped me a lot. thats why i'm posting it, although its just for wordpress users.
You could try my Linked Tree Map implementation.
I had the same issue and it had solved using two command lines:
sudo apt install php-zip
then reboot your web server, for Apache
sudo service apache2 restart
Another alternative to do the same thing is to filter on type=checkbox attribute:
$('input[type="checkbox"]').removeAttr('checked');
or
$('input[type="checkbox"]').prop('checked' , false);
Remeber that The difference between attributes and properties can be important in specific situations. Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.

If you don't want to show warnings as well as errors use
// Turn off all error reporting
error_reporting(0);
You can use double splat operator which is available since Ruby 2.0:
h = { a: 1, b: 2 }
h = { **h, c: 3 }
p h
# => {:a=>1, :b=>2, :c=>3}
I guess that the most correct answer is: Use :nth-child
(or, in this specific case, its counterpart :nth-last-child
). Most only know this selector by its first argument to grab a range of items based on a calculation with n, but it can also take a second argument "of [any CSS selector]".
Your scenario could be solved with this selector: .commentList .comment:nth-last-child(1 of .comment)
But being technically correct doesn't mean you can use it, though, because this selector is as of now only implemented in Safari.

I had observed that join is faster than sub.
There is a more efficient and less cumbersome solution for integers than a Collections.shuffle.
The problem is the same as successively picking items from only the un-picked items in a set and setting them in order somewhere else. This is exactly like randomly dealing cards or drawing winning raffle tickets from a hat or bin.
This algorithm works for loading any array and achieving a random order at the end of the load. It also works for adding into a List collection (or any other indexed collection) and achieving a random sequence in the collection at the end of the adds.
It can be done with a single array, created once, or a numerically ordered collectio, such as a List, in place. For an array, the initial array size needs to be the exact size to contain all the intended values. If you don't know how many values might occur in advance, using a numerically orderred collection, such as an ArrayList or List, where the size is not immutable, will also work. It will work universally for an array of any size up to Integer.MAX_VALUE which is just over 2,000,000,000. List objects will have the same index limits. Your machine may run out of memory before you get to an array of that size. It may be more efficient to load an array typed to the object types and convert it to some collection, after loading the array. This is especially true if the target collection is not numerically indexed.
This algorithm, exactly as written, will create a very even distribution where there are no duplicates. One aspect that is VERY IMPORTANT is that it has to be possible for the insertion of the next item to occur up to the current size + 1. Thus, for the second item, it could be possible to store it in location 0 or location 1. For the 20th item, it could be possible to store it in any location, 0 through 19. It is just as possible the first item to stay in location 0 as it is for it to end up in any other location. It is just as possible for the next new item to go anywhere, including the next new location.
The randomness of the sequence will be as random as the randomness of the random number generator.
This algorithm can also be used to load reference types into random locations in an array. Since this works with an array, it can also work with collections. That means you don't have to create the collection and then shuffle it or have it ordered on whatever orders the objects being inserted. The collection need only have the ability to insert an item anywhere in the collection or append it.
// RandomSequence.java
import java.util.Random;
public class RandomSequence {
public static void main(String[] args) {
// create an array of the size and type for which
// you want a random sequence
int[] randomSequence = new int[20];
Random randomNumbers = new Random();
for (int i = 0; i < randomSequence.length; i++ ) {
if (i == 0) { // seed first entry in array with item 0
randomSequence[i] = 0;
} else { // for all other items...
// choose a random pointer to the segment of the
// array already containing items
int pointer = randomNumbers.nextInt(i + 1);
randomSequence[i] = randomSequence[pointer];
randomSequence[pointer] = i;
// note that if pointer & i are equal
// the new value will just go into location i and possibly stay there
// this is VERY IMPORTANT to ensure the sequence is really random
// and not biased
} // end if...else
} // end for
for (int number: randomSequence) {
System.out.printf("%2d ", number);
} // end for
} // end main
} // end class RandomSequence
If you are using the JPA annotations, you can use @PrePersist
and @PreUpdate
event hooks do this:
@Entity
@Table(name = "entities")
public class Entity {
...
private Date created;
private Date updated;
@PrePersist
protected void onCreate() {
created = new Date();
}
@PreUpdate
protected void onUpdate() {
updated = new Date();
}
}
or you can use the @EntityListener
annotation on the class and place the event code in an external class.
Depending on the language you're using it's going to be something simple like
CInt(CDate("1970-1-1") - CDate(Today()))
Ironically enough, yesterday was day 40,000 if you use 1/1/1900 as "day zero" like many computer systems use.
