The static
modifier after import
is for retrieving/using static fields of a class. One area in which I use import static
is for retrieving constants from a class.
We can also apply import static
on static methods. Make sure to type import static
because static import
is wrong.
What is static import
in Java - JavaRevisited - A very good resource to know more about import static
.
What's missing from all the explanations is the fact that Java has a strict rule of class name = file name. Meaning if you have a class "Person", is must be in a file named "Person.java". Therefore, if one class tries to access "Person" the filename is not necessary, because it has got to be "Person.java".
Coming for C/C++, I have exact same issue. The answer is to create a new class (in a new file matching class name) and create a public string. This will be your "header" file. Then use that in your main file by using "extends" keyword.
Here is your answer:
Create a file called Include.java. In this file, add this:
public class Include {
public static String MyLongString= "abcdef";
}
Create another file, say, User.java. In this file, put:
import java.io.*;
public class User extends Include {
System.out.println(Include.MyLongString);
}
Call decode()
on a bytes
instance to get the text which it encodes.
str = bytes.decode()
The Gutenberg Project hosts Webster's Unabridged English Dictionary plus many other public domain literary works. Actually it looks like they've got several versions of the dictionary hosted with copyright from different years. The one I linked has a 2009 copyright. You may want to poke around the site and investigate the different versions of Webster's dictionary.
In order to execute multiple programs, I also needed a profiles
section:
<profiles>
<profile>
<id>traverse</id>
<activation>
<property>
<name>traverse</name>
</property>
</activation>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<configuration>
<executable>java</executable>
<arguments>
<argument>-classpath</argument>
<argument>org.dhappy.test.NeoTraverse</argument>
</arguments>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>
This is then executable as:
mvn exec:exec -Ptraverse
This is asking for your MySQL username and password.
You should enter these details, which will default to "root" and "" (i.e.: nothing) if you've not specified a password.
FWIW this happened to me today, but what happened was that I was running Ubuntu updates at the time, which were likely updating Postgres. Once the update completed, I was able to connect without a hitch.
For completeness' sake, I was trying to retrieve records from the database from a Rails console:
development (main):0 > a = MyModel.find 73694
PG::ConnectionBad: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
I'll assume that you're asking how to push a dependency out to a "well-known repository," and not simply asking how to update your POM.
If yes, then this is what you want to read.
And for anyone looking to set up an internal repository server, look here (half of the problem with using Maven 2 is finding the docs)
I would suggest using originalUrl instead of URL:
var url = req.protocol + '://' + req.get('host') + req.originalUrl;
See the description of originalUrl here: http://expressjs.com/api.html#req.originalUrl
In our system, we do something like this, so originalUrl is important to us:
foo = express();
express().use('/foo', foo);
foo.use(require('/foo/blah_controller'));
blah_controller looks like this:
controller = express();
module.exports = controller;
controller.get('/bar/:barparam', function(req, res) { /* handler code */ });
So our URLs have the format:
www.example.com/foo/bar/:barparam
Hence, we need req.originalUrl in the bar controller get handler.
Press CMD + ,
than click in show develop menu in menu bar. After that click Option + CMD + i
to open and close the inspector
Flat and simple config without rewrite, can work in some cases:
location / {
fastcgi_pass unix:/var/run/php5-fpm.sock;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /home/webuser/site/index.php;
}
My program does exactly what you are after, no prompts or anything, please see the following code.
This code will create all of the necessary directories if they don't already exist:
Directory.CreateDirectory(C:\dir\dira\dirb); // This code will create all of these directories
This code will download the given file to the given directory (after it has been created by the previous snippet:
private void install()
{
WebClient webClient = new WebClient(); // Creates a webclient
webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed); // Uses the Event Handler to check whether the download is complete
webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged); // Uses the Event Handler to check for progress made
webClient.DownloadFileAsync(new Uri("http://www.com/newfile.zip"), @"C\newfile.zip"); // Defines the URL and destination directory for the downloaded file
}
So using these two pieces of code you can create all of the directories and then tell the downloader (that doesn't prompt you to download the file to that location.

Probably part of Open Graph Protocol for Facebook.
Edit: guess not only Facebook - that's only one example of using it.
I followed these steps (for Mac).
In /etc/ssh/sshd_config
change

#PasswordAuthentication yes
to
ChallengeResponseAuthentication no

Now generate the RSA key:
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
(For me an RSA key worked. A DSA key did not work.)
A private key will be generated in ~/.ssh/id_rsa
along with ~/.ssh/id_rsa.pub
(public key).
Now move to the .ssh folder: cd ~/.ssh
Enter rm -rf authorized_keys
(sometimes multiple keys lead to an error).
Enter vi authorized_keys
Enter :wq
to save this empty file
Enter cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
Restart the SSH:
sudo launchctl stop com.openssh.sshd
sudo launchctl start com.openssh.sshd
public JSONObject RequestWithHttpUrlConn(String _url, String param){

out.flush();
out.close();

For final, it can be assigned different values at runtime when initialized. For example
class Test{
public final int a;
}
Test t1 = new Test();
t1.a = 10;
Test t2 = new Test();
t2.a = 20; //fixed
Thus each instance has different value of field a.
For static final, all instances share the same value, and can't be altered after first initialized.
class TestStatic{
public static final int a = 0;
}
TestStatic t1 = new TestStatic();
t1.a = 10; // ERROR, CAN'T BE ALTERED AFTER THE FIRST
TestStatic t2 = new TestStatic();
t1.a = 20; // ERROR, CAN'T BE ALTERED AFTER THE FIRST INITIALIZATION.
Try something like this
select Cast((SPGI09_EARLY_OVER_T – (SPGI09_OVER_WK_EARLY_ADJUST_T) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T + SPGR99_ON_TIME_Q)) as varchar(20) + '%' as percentageAmount
from CSPGI09_OVERSHIPMENT
I presume the value is a representation in percentage - if not convert it to a valid percentage total, then add the % sign and convert the column to varchar.
items.Remove(items.Length - 3)
string.Remove()
removes all items from that index to the end. items.length - 3
gets the index 3 chars from the end
I'm having the same issue in Eclipse Luna in my Ubuntu VM, but I just tried to Ctrl+click on a method and it worked (even though my mouse cursor didn't change to a pointer).
with virtual env activate
export FLASK_DEBUG=true
you can configure
export FLASK_APP=app.py # run.py
export FLASK_ENV = "development"
to start
flask run
the result
* Environment: development
* Debug mode: on
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
* Restarting with stat
* Debugger is active!
* Debugger PIN: xxx-xxx-xxx
and if you change
export FLASK_DEBUG=false
* Environment: development
* Debug mode: off

Use \t
and enclose the string with double-quotes:
$chunk = "abc\tdef\tghi";
The cin.clear()
clears the error flag on cin
(so that future I/O operations will work correctly), and then cin.ignore(10000, '\n')
skips to the next newline (to ignore anything else on the same line as the non-number so that it does not cause another parse failure). It will only skip up to 10000 characters, so the code is assuming the user will not put in a very long, invalid line.
All of the above answers are terrible awful - really. Even the one with 107 ups! The real answer is here guys:
Inheriting from the Error object - where is the message property?
TL;DR:
A. The reason message
isn't being set is that Error
is a function that returns a new Error object and does not manipulate this
in any way.
B. The way to do this right is to return the result of the apply from the constructor, as well as setting the prototype in the usual complicated javascripty way:
function MyError() {_x000D_
var temp = Error.apply(this, arguments);_x000D_
temp.name = this.name = 'MyError';_x000D_
this.message = temp.message;_x000D_
if(Object.defineProperty) {_x000D_
// getter for more optimizy goodness_x000D_
/*this.stack = */Object.defineProperty(this, 'stack', { _x000D_
get: function() {_x000D_
return temp.stack_x000D_
},_x000D_
configurable: true // so you can change it if you want_x000D_
})_x000D_
} else {_x000D_
this.stack = temp.stack_x000D_
}_x000D_
}_x000D_
//inherit prototype using ECMAScript 5 (IE 9+)_x000D_
MyError.prototype = Object.create(Error.prototype, {_x000D_
constructor: {_x000D_
value: MyError,_x000D_
writable: true,_x000D_
configurable: true_x000D_
}_x000D_
});_x000D_
_x000D_
var myError = new MyError("message");_x000D_
console.log("The message is: '" + myError.message + "'"); // The message is: 'message'_x000D_
console.log(myError instanceof Error); // true_x000D_
console.log(myError instanceof MyError); // true_x000D_
console.log(myError.toString()); // MyError: message_x000D_
console.log(myError.stack); // MyError: message \n _x000D_
// <stack trace ...>_x000D_
_x000D_
_x000D_
_x000D_
//for EMCAScript 4 or ealier (IE 8 or ealier), inherit prototype this way instead of above code:_x000D_
/*_x000D_
var IntermediateInheritor = function() {};_x000D_
IntermediateInheritor.prototype = Error.prototype;_x000D_
MyError.prototype = new IntermediateInheritor();_x000D_
*/
_x000D_
You could probably do some trickery to enumerate through all the non-enumerable properties of the tmp
Error to set them rather than explicitly setting only stack
and message
, but the trickery isn't supported in ie<9

There is no reliable way to check this. It's really under client's hand to tell you where it came from. You could imagine to use cookie or sessions informations put only on some pages of your website, but doing so your would break user experience with bookmarks.
in your css :
#txtComputer {
font-size: 24px;
}
You can style an input entirely (background, color, etc.) and even use the hover event.
It's a destructor. The function is guaranteed to be called when the object goes out of scope.
All the other answers didn't work for me. (including cors package, or setting headers through middleware)
For socket.io 3^ this worked without any extra packages.
const express = require('express');
const app = express();
const server = require('http').createServer(app);
const io = require('socket.io')(server, {
cors: {
origin: "*",
methods: ["GET", "POST"]
}
});
The time complexity, in Big O notation, for each function:
int recursiveFun1(int n)
{
if (n <= 0)
return 1;
else
return 1 + recursiveFun1(n-1);
}
This function is being called recursively n times before reaching the base case so its O(n)
, often called linear.
int recursiveFun2(int n)
{
if (n <= 0)
return 1;
else
return 1 + recursiveFun2(n-5);
}
This function is called n-5 for each time, so we deduct five from n before calling the function, but n-5 is also O(n)
.
(Actually called order of n/5 times. And, O(n/5) = O(n) ).
int recursiveFun3(int n)
{
if (n <= 0)
return 1;
else
return 1 + recursiveFun3(n/5);
}
This function is log(n) base 5, for every time we divide by 5
before calling the function so its O(log(n))
(base 5), often called logarithmic and most often Big O notation and complexity analysis uses base 2.
void recursiveFun4(int n, int m, int o)
{
if (n <= 0)
{
printf("%d, %d\n",m, o);
}
else
{
recursiveFun4(n-1, m+1, o);
recursiveFun4(n-1, m, o+1);
}
}
Here, it's O(2^n)
, or exponential, since each function call calls itself twice unless it has been recursed n times.
int recursiveFun5(int n)
{
for (i = 0; i < n; i += 2) {
// do something
}
if (n <= 0)
return 1;
else
return 1 + recursiveFun5(n-5);
}
And here the for loop takes n/2 since we're increasing by 2, and the recursion takes n/5 and since the for loop is called recursively, therefore, the time complexity is in
(n/5) * (n/2) = n^2/10,
due to Asymptotic behavior and worst-case scenario considerations or the upper bound that big O is striving for, we are only interested in the largest term so O(n^2)
.
Good luck on your midterms ;)
I had the same issue. I tired below solutions but didn’t worked :
Clean Project (cmd + shift + k)
and even Clean Project Build (cmd + shift + alt + k)
Deleted Derived data
and Module Cache content
Below workaround to this issue :
IBOutlet / IBAction
manually (copy paste preferred)Utilites
window Connection Inspector
IBOutlet
and IBAction
written in source file with Interface Builder.I believe it would be:
void setCurrent(boolean current)
boolean isCurrent()
In general case of writing this unsupported encoding string (let's say data_that_causes_this_error
) to some file (for e.g. results.txt
), this works
f = open("results.txt", "w")
f.write(data_that_causes_this_error.encode('utf-8'))
f.close()
I see three possibilities. The first two cut off the digits, the last one rounds to the nearest Integer.
double d = 9.5;
int i = (int)d;
//i = 9
Double D = 9.5;
int i = Integer.valueOf(D.intValue());
//i = 9
double d = 9.5;
Long L = Math.round(d);
int i = Integer.valueOf(L.intValue());
//i = 10
As mentioned by Zeeshan, the logrotate options size
, minsize
, maxsize
are triggers for rotation.
To better explain it. You can run logrotate as often as you like, but unless a threshold is reached such as the filesize being reached or the appropriate time passed, the logs will not be rotated.
The size options do not ensure that your rotated logs are also of the specified size. To get them to be close to the specified size you need to call the logrotate program sufficiently often. This is critical.
For log files that build up very quickly (e.g. in the hundreds of MB a day), unless you want them to be very large you will need to ensure logrotate is called often! this is critical.
Therefore to stop your disk filling up with multi-gigabyte log files you need to ensure logrotate is called often enough, otherwise the log rotation will not work as well as you want.
on Ubuntu, you can easily switch to hourly rotation by moving the script /etc/cron.daily/logrotate to /etc/cron.hourly/logrotate
Or add
*/5 * * * * /etc/cron.daily/logrotate
To your /etc/crontab file. To run it every 5 minutes.
The size
option ignores the daily, weekly, monthly time options. But minsize & maxsize take it into account.
The man page is a little confusing there. Here's my explanation.
minsize
rotates only when the file has reached an appropriate size and the set time period has passed. e.g. minsize 50MB + daily
If file reaches 50MB before daily time ticked over, it'll keep growing until the next day.
maxsize
will rotate when the log reaches a set size or the appropriate time has passed.
e.g. maxsize 50MB + daily.
If file is 50MB and we're not at the next day yet, the log will be rotated. If the file is only 20MB and we roll over to the next day then the file will be rotated.
size
will rotate when the log > size. Regardless of whether hourly/daily/weekly/monthly is specified. So if you have size 100M - it means when your log file is > 100M the log will be rotated if logrotate is run when this condition is true. Once it's rotated, the main log will be 0, and a subsequent run will do nothing.
So in the op's case. Specficially 50MB max I'd use something like the following:
/var/log/logpath/*.log {
maxsize 50M
hourly
missingok
rotate 8
compress
notifempty
nocreate
}
Which means he'd create 8hrs of logs max. And there would be 8 of them at no more than 50MB each. Since he's saying that he's getting multi gigabytes each day and assuming they build up at a fairly constant rate, and maxsize is used he'll end up with around close to the max reached for each file. So they will be likely close to 50MB each. Given the volume they build, he would need to ensure that logrotate is run often enough to meet the target size.
Since I've put hourly there, we'd need logrotate to be run a minimum of every hour. But since they build up to say 2 gigabytes per day and we want 50MB... assuming a constant rate that's 83MB per hour. So you can imagine if we run logrotate every hour, despite setting maxsize to 50 we'll end up with 83MB log's in that case. So in this instance set the running to every 30 minutes or less should be sufficient.
Ensure logrotate is run every 30 mins.

Simply add style="line-height:0"
to each cell. This works in IE because it sets the line-height of both existant and non-existant text to about 19px and that forces the cells to expand vertically in most versions of IE. Regardless of whether or not you have text this needs to be done for IE to correctly display rows less than 20px high.
Using NOT EXISTS
:
INSERT INTO TABLE_2
(id, name)
SELECT t1.id,
t1.name
FROM TABLE_1 t1
WHERE NOT EXISTS(SELECT id
FROM TABLE_2 t2
WHERE t2.id = t1.id)
Using NOT IN
:
INSERT INTO TABLE_2
(id, name)
SELECT t1.id,
t1.name
FROM TABLE_1 t1
WHERE t1.id NOT IN (SELECT id
FROM TABLE_2)
Using LEFT JOIN/IS NULL
:
INSERT INTO TABLE_2
(id, name)
SELECT t1.id,
t1.name
FROM TABLE_1 t1
LEFT JOIN TABLE_2 t2 ON t2.id = t1.id
WHERE t2.id IS NULL
Of the three options, the LEFT JOIN/IS NULL
is less efficient. See this link for more details.
Here is a summary.

Using display: table-cell
is fine, provided that you're aware that it won't work in IE6/7. Other than that, it's safe: Is there a disadvantage of using `display:table-cell`on divs?
To fix the space at the bottom, add vertical-align: bottom
to the actual img
s:
Removing the space between the images boils down to this: bikeshedding CSS3 property alternative?
So, here's a demo with the whitespace removed in your HTML: http://jsfiddle.net/WSFnX/4/
That code doesn't work very well i fixed it a little bit
var el = $('.caja-pago');
var elpos_original = el.offset().top;
$(window).scroll(function(){
var elpos = el.offset().top;
var windowpos = $(window).scrollTop();
var finaldestination = windowpos;
if(windowpos<elpos_original) {
finaldestination = elpos_original;
el.stop().animate({'top':400},500);
} else {
el.stop().animate({'top':windowpos+10},500);
}
});
a = list(input("Enter a string\t: "))
def fun(a):
c =' '.join(['0'*(8-len(bin(ord(i))[2:]))+(bin(ord(i))[2:]) for i in a])
return c
print(fun(a))
If you were only interested in 'z', you could create a function-based index.
CREATE INDEX users_z_idx ON users (INSTR(last_name,'z'))
Then your query would use WHERE INSTR(last_name,'z') > 0
.
With this approach you would have to create a separate index for each character you might want to search for. I suppose if this is something you do often, it might be worth creating one index for each letter.
Also, keep in mind that if your data has the names capitalized in the standard way (e.g., "Zaxxon"), then both your example and mine would not match names that begin with a Z. You can correct for this by including LOWER in the search expression: INSTR(LOWER(last_name),'z')
.
Here cascade, in the context of remove, means that the children are removed if you remove the parent. Not the association. If you are using Hibernate as your JPA provider, you can do it using hibernate specific cascade.
You can't (and shouldn't) block processing with a sleep function. However, you can use setTimeout
to kick off a function after a delay:
setTimeout(function(){alert("hi")}, 1000);
Depending on your needs, setInterval
might be useful, too.
FirstOrDefault
returns the default value of a type if no item matches the predicate. For reference types that is null
. Thats the reason for the exception.
So you just have to check for null
first:
string displayName = null;
var keyValue = Dictionary
.FirstOrDefault(x => x.Value.ID == long.Parse(options.ID));
if(keyValue != null)
{
displayName = keyValue.Value.DisplayName;
}
But what is the key of the dictionary if you are searching in the values? A Dictionary<tKey,TValue>
is used to find a value by the key. Maybe you should refactor it.
Another option is to provide a default value with DefaultIfEmpty
:
string displayName = Dictionary
.Where(kv => kv.Value.ID == long.Parse(options.ID))
.Select(kv => kv.Value.DisplayName) // not a problem even if no item matches
.DefaultIfEmpty("--Option unknown--") // or no argument -> null
.First(); // cannot cause an exception
Hello World!
You see, the main question while using hidden input is what kind of data you want to pass?
I will assume that you are trying to pass the user ID.
Which is not a really good idea to pass it here because field() method will generate input
and the value will be shown to user as we can't hide html from the users browser. This if you really care about security of your website.
please check this link, and you will see that it's impossible to hide value attribute from users to see.
so what to do then?
See, this is the core of OOP in PHP.
and I quote from Matt Zandstr in his great book PHP Objects, Patterns, and Practice fifth edition
I am still stuck with a great deal of unwanted flexibility, though. I rely on the client coder to change a ShopProduct object’s properties from their default values. This is problematic in two ways. First, it takes five lines to properly initialize a ShopProduct object, and no coder will thank you for that. Second, I have no way of ensuring that any of the properties are set when a ShopProduct object is initialized. What I need is a method that is called automatically when an object is instantiated from a class.
Please check this example of using __construct() method which is mentioned in his book too.
class ShopProduct {
public $title;
public $producerMainName;
public $producerFirstName;
public $price = 0;
public function __construct($title,$firstName,$mainName,$price) {
$this->title = $title;
$this->producerFirstName = $firstName;
$this->producerMainName = $mainName;
$this->price = $price;
}
}
$product1 = new ShopProduct("My Antonia","Willa","Cather",5.99 );
print "author: {$product1->getProducer()}\n";
This produces the following:
author: Willa Cather
Class Car {
private $user_id;
//.. your properties
public function __construct($title,$firstName,$mainName,$price){
$this->user_id = \Yii::$app->user->id;
//..Your magic
}
}
The Interface describes either a contract for a class or a new type. It is a pure Typescript element, so it doesn't affect Javascript.
A model, and namely a class, is an actual JS function which is being used to generate new objects.
I want to load JSON data from a URL and bind to the Interface/Model.
Go for a model, otherwise it will still be JSON in your Javascript.
Yes, you can do ajax request to server with your data in request parameters, like this (very simple):
Note that the following code uses jQuery
jQuery.ajax({
type: "POST",
url: 'your_functions_address.php',
dataType: 'json',
data: {functionname: 'add', arguments: [1, 2]},
success: function (obj, textstatus) {
if( !('error' in obj) ) {
yourVariable = obj.result;
}
else {
console.log(obj.error);
}
}
});
and your_functions_address.php like this:
<?php
header('Content-Type: application/json');
$aResult = array();
if( !isset($_POST['functionname']) ) { $aResult['error'] = 'No function name!'; }
if( !isset($_POST['arguments']) ) { $aResult['error'] = 'No function arguments!'; }
if( !isset($aResult['error']) ) {
switch($_POST['functionname']) {
case 'add':
if( !is_array($_POST['arguments']) || (count($_POST['arguments']) < 2) ) {
$aResult['error'] = 'Error in arguments!';
}
else {
$aResult['result'] = add(floatval($_POST['arguments'][0]), floatval($_POST['arguments'][1]));
}
break;
default:
$aResult['error'] = 'Not found function '.$_POST['functionname'].'!';
break;
}
}
echo json_encode($aResult);

You will have to save the relationship on the server side. The value is the only part that is transmitted when the form is posted. You could do something nasty like...
<option value="2|Dog">Dog</option>
Then split the result apart if you really wanted to, but that is an ugly hack and a waste of bandwidth assuming the numbers are truly unique and have a one to one relationship with the text.
The best way would be to create an array, and loop over the array to create the HTML. Once the form is posted you can use the value to look up the text in that same array.
I Hope that this helps you out... Because I tried all the answers but nothing worked perfectly. So, I had to come up with a solution on my own.
#horizontal-style {
padding-inline-start: 0 !important; // Just in case if you find that there is an extra padding at the start of the line
justify-content: space-around;
display: flex;
}
#horizontal-style a {
text-align: center;
color: white;
text-decoration: none;
}
You can simply add your JavaScript in body segment like this:
<body>
<script src="myScript.js"> </script>
</body>
myScript
will be the file name for your JavaScript. Just write the code and enjoy!

To understand how a docker image was built, use the
docker history --no-trunc
command.
You can build a docker file from an image, but it will not contain everything you would want to fully understand how the image was generated. Reasonably what you can extract is the MAINTAINER, ENV, EXPOSE, VOLUME, WORKDIR, ENTRYPOINT, CMD, and ONBUILD parts of the dockerfile.
The following script should work for you:
#!/bin/bash
docker history --no-trunc "$1" | \
sed -n -e 's,.*/bin/sh -c #(nop) \(MAINTAINER .*[^ ]\) *0 B,\1,p' | \
head -1
docker inspect --format='{{range $e := .Config.Env}}
ENV {{$e}}
{{end}}{{range $e,$v := .Config.ExposedPorts}}
EXPOSE {{$e}}
{{end}}{{range $e,$v := .Config.Volumes}}
VOLUME {{$e}}
{{end}}{{with .Config.User}}USER {{.}}{{end}}
{{with .Config.WorkingDir}}WORKDIR {{.}}{{end}}
{{with .Config.Entrypoint}}ENTRYPOINT {{json .}}{{end}}
{{with .Config.Cmd}}CMD {{json .}}{{end}}
{{with .Config.OnBuild}}ONBUILD {{json .}}{{end}}' "$1"
I use this as part of a script to rebuild running containers as images: https://github.com/docbill/docker-scripts/blob/master/docker-rebase
The Dockerfile is mainly useful if you want to be able to repackage an image.
The thing to keep in mind, is a docker image can actually just be the tar backup of a real or virtual machine. I have made several docker images this way. Even the build history shows me importing a huge tar file as the first step in creating the image...
From what suggest others and from pathlib documentation, a simple and clear solution is the following (suppose the file we need to refer to: Test/data/users.csv
:
# This file location: Tests/src/long/module/subdir/some_script.py
from pathlib import Path
# back to Tests/
PROJECT_ROOT = Path(__file__).parents[4]
# then down to Test/data/users.csv
CSV_USERS_PATH = PROJECT_ROOT / 'data' / 'users.csv'
with CSV_USERS_PATH.open() as users:
print(users.read())
Now this looks a bit odd to me, because if you move some_script.py
around, the path to the root of our project may change (we would need to modify parents[4]
). On the other hand I found a solution that I prefer based on the same idea.
Suppose we have the following directory structure:
Tests
+-- data
¦ +-- users.csv
+-- src
+-- long
¦ +-- module
¦ +-- subdir
¦ +-- some_script.py
+-- main.py
+-- paths.py
The paths.py
file will be responsible for storing the root location of our projet:
from pathlib import Path
PROJECT_ROOT = Path(__file__).parents[1]
All scripts can now use paths.PROJECT_ROOT
to express absolute paths from the root of the project. For example in src/long/module/subdir/some_script.py
we could have:
from paths import PROJECT_ROOT
CSV_USERS_PATH = PROJECT_ROOT / 'data' / 'users.csv'
def hello():
with CSV_USERS_PATH.open() as f:
print(f.read())
And everything goes as expected:
~/Tests/src/$ python main.py
/Users/cglacet/Tests/data/users.csv
hello, user
~/Tests/$ python src/main.py
/Users/cglacet/Tests/data/users.csv
hello, user
The main.py
script simply is:
from long.module.subdir import some_script
some_script.hello()
>>> arr = numpy.array(((2,2),(2,-2)))
>>> tuple(map(tuple, arr))
((2, 2), (2, -2))
If this is the bug with the edmx file located in a folder it is now fixed - download and install VS 2012 Update 1. You can get it from: http://www.microsoft.com/visualstudio/eng/downloads#d-visual-studio-2012-update
I am having the same problem, and I guess the way of doing this will be to remove the data-toggle attribute and have a custom handler for the links.
Something in the lines of:
$("a[data-target=#myModal]").click(function(ev) {
ev.preventDefault();
var target = $(this).attr("href");
// load the url and show modal on success
$("#myModal .modal-body").load(target, function() {
$("#myModal").modal("show");
});
});
Will try it later and post comments.
No siblings solution:
var x = $('#xxx').parent().html();
alert(x);
Universal solution:
// no cloning necessary
var x = $('#xxx').wrapAll('<div>').parent().html();
alert(x);
Fiddle here: http://jsfiddle.net/ezmilhouse/Mv76a/
Swift 4 example:
var filePath: String {
//manager lets you examine contents of a files and folders in your app.
let manager = FileManager.default
//returns an array of urls from our documentDirectory and we take the first
let url = manager.urls(for: .documentDirectory, in: .userDomainMask).first
//print("this is the url path in the document directory \(String(describing: url))")
//creates a new path component and creates a new file called "Data" where we store our data array
return(url!.appendingPathComponent("Data").path)
}
I put the check in my loadData function which I called in viewDidLoad.
override func viewDidLoad() {
super.viewDidLoad()
loadData()
}
Then I defined loadData below.
func loadData() {
let manager = FileManager.default
if manager.fileExists(atPath: filePath) {
print("The file exists!")
//Do what you need with the file.
ourData = NSKeyedUnarchiver.unarchiveObject(withFile: filePath) as! Array<DataObject>
} else {
print("The file DOES NOT exist! Mournful trumpets sound...")
}
}
I have done to find out the data type in the table at link_server using openquery and the results were successful.

Go to Menu Tool -> SQL Output, Run the PL/SQL statement, the output will show on SQL Output panel.
I do it in Kotlin like this:
open class BaseAppCompatActivity : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener {
protected lateinit var drawerLayout: DrawerLayout
protected lateinit var navigationView: NavigationView
@Inject
lateinit var loginService: LoginService
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
Log.d("BaseAppCompatActivity", "onCreate()")
App.getComponent().inject(this)
drawerLayout = findViewById(R.id.drawer_layout) as DrawerLayout
val toolbar = findViewById(R.id.toolbar) as Toolbar
setSupportActionBar(toolbar)
navigationView = findViewById(R.id.nav_view) as NavigationView
navigationView.setNavigationItemSelectedListener(this)
val toggle = ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)
drawerLayout.addDrawerListener(toggle)
toggle.syncState()
toggle.isDrawerIndicatorEnabled = true
val navigationViewHeaderView = navigationView.getHeaderView(0)
navigationViewHeaderView.login_txt.text = SharedKey.username
}
private inline fun <reified T: Activity> launch():Boolean{
if(this is T) return closeDrawer()
val intent = Intent(applicationContext, T::class.java)
startActivity(intent)
finish()
return true
}
private fun closeDrawer(): Boolean {
drawerLayout.closeDrawer(GravityCompat.START)
return true
}
override fun onNavigationItemSelected(item: MenuItem): Boolean {
val id = item.itemId
when (id) {
R.id.action_tasks -> {
return launch<TasksActivity>()
}
R.id.action_contacts -> {
return launch<ContactActivity>()
}
R.id.action_logout -> {
createExitDialog(loginService, this)
}
}
return false
}
}
Activities for drawer must inherit this BaseAppCompatActivity
, call super.onCreate
after content is set (actually, can be moved to some init method) and have corresponding elements for ids in their layout
The best way to avoid this kind of issues it to build properties programmatically and then store them. For example, using code like this:
java.util.Properties props = new java.util.Properties();
props.setProperty("table.whereclause", "where id=100");
props.store(System.out, null);
This would output to System.out the properly escaped version.
In my case the output was:
#Mon Aug 12 13:50:56 EEST 2013
table.whereclause=where id\=100
As you can see, this is an easy way to generate content of .properties files that's guaranteed to be correct. And you can put as many properties as you want.
I don't know if this has really been solved or not... but by looking at all the other answers, nothing seems quite clear. The best way I found to do this is to put the same code, that was used to populate your datagridview
into a method and pass it your form's datagridview
, as so:
public void ConnectAndPopulateDataGridView(DataGridView dataGridView)
{ }
The code within the method is the exact same as the code used to populate the datagirdview
originally, except for the datagridview
name changing to whatever you called it in your method.
Now this method is called in your parent form.
The child form is launched via a .ShowDialog()
then the method is called after so that it is called right after the child for is closed... as so:
ChildForm.ShowDialog();
ConnectAndPopulateDataGridView(dataGridView1);
Using the latest cross-platform Google Maps URLs: Even if google maps app is missing it will open in browser
Example https://www.google.com/maps/dir/?api=1&origin=81.23444,67.0000&destination=80.252059,13.060604
Uri.Builder builder = new Uri.Builder();
builder.scheme("https")
.authority("www.google.com")
.appendPath("maps")
.appendPath("dir")
.appendPath("")
.appendQueryParameter("api", "1")
.appendQueryParameter("destination", 80.00023 + "," + 13.0783);
String url = builder.build().toString();
Log.d("Directions", url);
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
This solution is very similar to that provided by @gdw2 , only that the string formatting is correctly done to match what you asked for - "Should be as compact as possible"
>>> import datetime
>>> a = datetime.datetime.now()
>>> "%s:%s.%s" % (a.minute, a.second, str(a.microsecond)[:2])
'31:45.57'
I know that is late to answer but could be useful for someone else You can use sub-query and convert the null to 0
SELECT *
FROM (SELECT CASE WHEN id_field IS NULL
THEN 0
ELSE id_field
END AS id_field
FROM tbl_name) AS tbl
WHERE tbl.id_field IN ('value1', 'value2', 'value3', 0)
You can use ng-required for your validation scenario ("if these 3 fields are filled in, then this field is required":
<div ng-app>
<input type="text" ng-model="field1" placeholder="Field1">
<input type="text" ng-model="field2" placeholder="Field2">
<input type="text" ng-model="field3" placeholder="Field3">
<input type="text" ng-model="dependentField" placeholder="Custom validation"
ng-required="field1 && field2 && field3">
</div>
In the same way you are trying to run cron.php, you can run another PHP script. You will have to do so via the CLI interface though.
#!/usr/bin/env php
<?php
# This file would be say, '/usr/local/bin/run.php'
// code
echo "this was run from CRON";
Then, add an entry to the crontab:
* * * * * /usr/bin/php -f /usr/local/bin/run.php &> /dev/null
If the run.php script had executable permissions, it could be listed directly in the crontab, without the /usr/bin/php part as well. The 'env php' part, in the script, would find the appropriate program to actually run the PHP code. So, for the 'executable' version - add executable permission to the file:
chmod +x /usr/local/bin/run.php
and then, add the following entry into crontab:
* * * * * /usr/local/bin/run.php &> /dev/null
Wouldn't
(int) Math.Min(Int32.MaxValue, longValue)
be the correct way, mathematically speaking?
If you want to permanently ignore these files, a simple way to add them to .gitignore
is:
git ls-files --others --exclude-standard >> .gitignore
This will enumerate all files inside untracked directories, which may or may not be what you want.
I don't think you have what you need with:
0 0 */3 * * ## <<< WARNING!!! CAUSES UNEVEN INTERVALS AT END OF MONTH!!
Unfortunately, the */3 is setting the interval on every n day of the month and not every n days. See: explanation here. At the end of the month there is recurring issue guaranteed.
1st at 2019-02-01 00:00:00
then at 2019-02-04 00:00:00 << 3 days, etc. OK
then at 2019-02-07 00:00:00
...
then at 2019-02-25 00:00:00
then at 2019-01-28 00:00:00
then at 2019-03-01 00:00:00 << 1 day WRONG
then at 2019-03-04 00:00:00
...
According to this article, you need to add some modulo math to the command being executed to get a TRUE "every N days". For example:
0 0 * * * bash -c '(( $(date +\%s) / 86400 \% 3 == 0 )) && runmyjob.sh
In this example, the job will be checked daily at 12:00 AM, but will only execute when the number of days since 01-01-1970 modulo 3 is 0.
If you want it to be every 3 days from a specific date, use the following format:
0 0 * * * bash -c '(( $(date +\%s -d "2019-01-01") / 86400 \% 3 == 0 )) && runmyjob.sh
I was dealing with DateTimeOffset
and unfortunately the "o" prints out "+0000" not "Z".
So I ended up with:
dateTimeOffset.UtcDateTime.ToString("o")
SELECT [T1].*
FROM [Table1] AS [T1]
WHERE NOT EXISTS (SELECT
1 AS [C1]
FROM [Table2] AS [T2]
WHERE ([T2].[MAKE] = [T1].[MAKE]) AND
([T2].[MODEL] = [T1].[MODEL]) AND
([T2].[Serial Number] = [T1].[Serial Number])
);
Another way of joining two lines without placing cursor to that line is:
:6,6s#\n##
Here 6 is the line number to which another line will be join. To display the line number, use :set nu
.
If we are on the cursor where the next line should be joined, then:
:s#\n##
In both cases we don't need g
like :s#\n##g
, because on one line only one \n
exist.

At first make sure you have mysql installed properly. You can ensure it just by checking that whether you can access mysql using mysql command promp. So if you mysql is working then probably it is not loading. For that follow the steps given below
First of all, you must find your php.ini. It could be anywhere but if you create a small php file with the
<?php phpinfo(); ?>
script it will tell you where it is. Just look at the path of loaded configuration file. Common places include /etc/apache/, /etc/php4/apache2/php.ini, /etc/php5/apache2/php.ini or even /usr/local/lib/php.ini for Windows it may be C:\Users\username\PHP\php.ini
Edit your server’s php.ini and look for the following line. Remove the ‘;’ from the start of the line and restart Apache. Things should work fine now!
;extension=mysql.so
should become
extension=mysql.so
For windows it will be
;extension=mysql.dll
should become
extension=mysql.dll
With the command:
sudo apt-get remove --purge mysql\*
you can delete anything related to packages named mysql. Those commands are only valid on debian / debian-based linux distributions (Ubuntu for example).
You can list all installed mysql packages with the command:
sudo dpkg -l | grep -i mysql
For more cleanup of the package cache, you can use the command:
sudo apt-get clean
Also, remember to use the command:
sudo updatedb
Otherwise the "locate" command will display old data.
To install mysql again, use the following command:
sudo apt-get install libmysqlclient-dev mysql-client
This will install the mysql client, libmysql and its headers files.
To install the mysql server, use the command:
sudo apt-get install mysql-server
this may help. add the code in your custom Application or BaseActivity
/**
* ?? getResource ??,????????
*
* @return
*/
@Override
public Resources getResources() {
Resources resources = super.getResources();
if (resources != null && resources.getConfiguration().fontScale != 1) {
Configuration configuration = resources.getConfiguration();
configuration.fontScale = 1;
resources.updateConfiguration(configuration, resources.getDisplayMetrics());
}
return resources;
}
however, Resource#updateConfiguration is deplicated in API level 25, which means it will be unsupported some day in the future.
An actual JSON request would look like this:
data: '{"command":"on"}',
Where you're sending an actual JSON string. For a more general solution, use JSON.stringify()
to serialize an object to JSON, like this:
data: JSON.stringify({ "command": "on" }),
To support older browsers that don't have the JSON
object, use json2.js which will add it in.
What's currently happening is since you have processData: false
, it's basically sending this: ({"command":"on"}).toString()
which is [object Object]
...what you see in your request.
One possible PHP solution:
// load XML to SimpleXML
$x = simplexml_load_string($xmlstr);
// index it by title once
$index = array();
foreach ($x->CD as &$cd) {
$title = strtolower((string)$cd['title']);
if (!array_key_exists($title, $index)) $index[$title] = array();
$index[$title][] = &$cd;
}
// query the index
$result = $index[strtolower("EMPIRE BURLESQUE")];
The code you have posted here and code on your site both are different. There is a break <br>
after second image, so the third image into new line, remove this <br>
and it will display correctly.
There is a simple solution to this problem using this library. I store an instance of the CallRecord class in MyService.class. When the service is first initialized, the following code is executed:
public class MyService extends Service {
public static CallRecord callRecord;
@Override
public void onCreate() {
super.onCreate();
callRecord = new CallRecord.Builder(this)
.setRecordFileName("test")
.setRecordDirName("Download")
.setRecordDirPath(Environment.getExternalStorageDirectory().getPath()) // optional & default value
.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB) // optional & default value
.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB) // optional & default value
.setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION) // optional & default value
.setShowSeed(false) // optional, default=true ->Ex: RecordFileName_incoming.amr || RecordFileName_outgoing.amr
.build();
callRecord.enableSaveFile();
callRecord.startCallReceiver();
}
@Override
public void onDestroy() {
super.onDestroy();
callRecord.stopCallReceiver();
}
}
Next, do not forget to specify permissions in the manifest. (I may have some extras here, but keep in mind that some of them are necessary only for newer versions of Android)
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.PROCESS_INCOMING_CALLS" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Also it is crucial to request some permissions at the first start of the application. A guide is provided here.
If my code doesn't work, alternative code can be found here. I hope I helped you.
You should use @input
:
<input @input="handleInput" />
@input
fires when user changes input value.
@change
fires when user changed value and unfocus input (for example clicked somewhere outside)

Have you looked into using the CSS z-index
property to make the container dev be "on top" of the svg? Because the div is (presumably) transparent, you will still see the image exactly as before.
This, I believe, is the best-practice, non-hack, intended way of solving your problem. z-index
is only useful for elements that have a position
property of fixed
, relative
, or, as you've heard, absolute
. However, you don't actually have to move the object.
For example:
<style>
.svgwrapper {
position: relative;
z-index: 1;
}
</style>
<div class="svgwrapper" onClick="function();">
<object src="blah" />
</div>
For what it's worth, it would also be a little more elegant and safe to not use onClick at all, but instead to bind the click event using javascript. That's another issue altogether, though.
I concluded that wc -l
:s method of counting newlines is fine but returns non-intuitive results on files where the last line doesn't end with a newline.
And @er.vikas solution based on LineNumberReader but adding one to the line count returned non-intuitive results on files where the last line does end with newline.
I therefore made an algo which handles as follows:
@Test
public void empty() throws IOException {
assertEquals(0, count(""));
}
@Test
public void singleNewline() throws IOException {
assertEquals(1, count("\n"));
}
@Test
public void dataWithoutNewline() throws IOException {
assertEquals(1, count("one"));
}
@Test
public void oneCompleteLine() throws IOException {
assertEquals(1, count("one\n"));
}
@Test
public void twoCompleteLines() throws IOException {
assertEquals(2, count("one\ntwo\n"));
}
@Test
public void twoLinesWithoutNewlineAtEnd() throws IOException {
assertEquals(2, count("one\ntwo"));
}
@Test
public void aFewLines() throws IOException {
assertEquals(5, count("one\ntwo\nthree\nfour\nfive\n"));
}
And it looks like this:
static long countLines(InputStream is) throws IOException {
try(LineNumberReader lnr = new LineNumberReader(new InputStreamReader(is))) {
char[] buf = new char[8192];
int n, previousN = -1;
//Read will return at least one byte, no need to buffer more
while((n = lnr.read(buf)) != -1) {
previousN = n;
}
int ln = lnr.getLineNumber();
if (previousN == -1) {
//No data read at all, i.e file was empty
return 0;
} else {
char lastChar = buf[previousN - 1];
if (lastChar == '\n' || lastChar == '\r') {
//Ending with newline, deduct one
return ln;
}
}
//normal case, return line number + 1
return ln + 1;
}
}
If you want intuitive results, you may use this. If you just want wc -l
compatibility, simple use @er.vikas solution, but don't add one to the result and retry the skip:
try(LineNumberReader lnr = new LineNumberReader(new FileReader(new File("File1")))) {
while(lnr.skip(Long.MAX_VALUE) > 0){};
return lnr.getLineNumber();
}
To open an url in a new tab, you can use the Link tag as below:
<Link to="/yourRoute" target="_blank">
Open YourRoute in a new tab
</Link>
It's nice to keep in mind that the <Link>
element gets translated to an <a>
element, and as per react-router-dom docs, you can pass any props you'd like to be on it such as title, id, className, etc.
One common convention is to use a "_" as a variable name for the elements of the tuple you wish to ignore. For instance:
def f():
return 1, 2, 3
_, _, x = f()
I just had to update legacy Weblogic 8 app to use a data-source instead of hard-coded JDBC string. Datasource JNDI name on the configuration tab in the Weblogic admin showed: "weblogic.jdbc.ESdatasource", below are two ways that worked:
Context ctx = new InitialContext();
DataSource dataSource;
try {
dataSource = (DataSource) ctx.lookup("weblogic.jdbc.ESdatasource");
response.getWriter().println("A " +dataSource);
}catch(Exception e) {
response.getWriter().println("A " + e.getMessage() + e.getCause());
}
//or
try {
dataSource = (DataSource) ctx.lookup("weblogic/jdbc/ESdatasource");
response.getWriter().println("F "+dataSource);
}catch(Exception e) {
response.getWriter().println("F " + e.getMessage() + e.getCause());
}
//use your datasource
conn = datasource.getConnection();
That's all folks. No passwords and initial context factory needed from the inside of Weblogic app.
Here is my technique I'd like to share. Works well so long as your clr property types are sql equivalent types eg. bool -> bit, long -> bigint, string -> nchar/char/varchar/nvarchar, decimal -> money
public void SaveTransaction(Transaction transaction)
{
using (var con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConString"].ConnectionString))
{
using (var cmd = new SqlCommand("spAddTransaction", con))
{

foreach (var prop in transaction.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))
cmd.Parameters.AddWithValue("@" + prop.Name, prop.GetValue(transaction, null));
con.Open();
cmd.ExecuteNonQuery();
}

I find the most valuable feature of .FormulaR1C1 is sheer speed. Versus eg a couple of very large loops filling some data into a sheet, If you can convert what you are doing into a .FormulaR1C1 form. Then a single operation eg myrange.FormulaR1C1 = "my particular formuala" is blindingly fast (can be a thousand times faster). No looping and counting - just fill the range at high speed.

Finalizers in Java are bad. They add a lot of overhead to garbage collection. Avoid them whenever possible.
The shutdownHook will only get called when the VM is shutting down. I think it very well may do what you want.
you can use the isUserInRole method of the HttpServletRequest object.
something like:
public String createForm(HttpSession session, HttpServletRequest request, ModelMap modelMap) {
if (request.isUserInRole("ROLE_ADMIN")) {
// code here

}
To add to James's example, it seems you always have to create an intermediate when performing calculations on NA-containing data frames.
For instance, adding two columns (A and B) together from a data frame dfr
:
temp.df <- data.frame(dfr) # copy the original
temp.df[is.na(temp.df)] <- 0
dfr$C <- temp.df$A + temp.df$B # or any other calculation
remove('temp.df')
When I do this I throw away the intermediate afterwards with remove
/rm

Should usually do the trick, but it depends on your sites directories. This will work for your example
you can use the new HTML 5 file api to read file contents

but this won't work on every browser so you probably need a server side fallback.
In our case it was due to the Recovery Model on the primary database having been changed after we did the backup in preparation for setting up log shipping.
Ensuring the Recovery Model was set to Full Recovery before doing the backup and setting up log shipping resolved it for us.
Sorry EMS, but I actually just got another response from the matplotlib mailling list (Thanks goes out to Benjamin Root).
The code I am looking for is adjusting the savefig call to:
fig.savefig('samplefigure', bbox_extra_artists=(lgd,), bbox_inches='tight')
#Note that the bbox_extra_artists must be an iterable
This is apparently similar to calling tight_layout, but instead you allow savefig to consider extra artists in the calculation. This did in fact resize the figure box as desired.
import matplotlib.pyplot as plt
import numpy as np
plt.gcf().clear()
x = np.arange(-2*np.pi, 2*np.pi, 0.1)
fig = plt.figure(1)
ax = fig.add_subplot(111)
ax.plot(x, np.sin(x), label='Sine')
ax.plot(x, np.cos(x), label='Cosine')
ax.plot(x, np.arctan(x), label='Inverse tan')
handles, labels = ax.get_legend_handles_labels()
lgd = ax.legend(handles, labels, loc='upper center', bbox_to_anchor=(0.5,-0.1))
text = ax.text(-0.2,1.05, "Aribitrary text", transform=ax.transAxes)
ax.set_title("Trigonometry")
ax.grid('on')
fig.savefig('samplefigure', bbox_extra_artists=(lgd,text), bbox_inches='tight')
This produces:
[edit] The intent of this question was to completely avoid the use of arbitrary coordinate placements of arbitrary text as was the traditional solution to these problems. Despite this, numerous edits recently have insisted on putting these in, often in ways that led to the code raising an error. I have now fixed the issues and tidied the arbitrary text to show how these are also considered within the bbox_extra_artists algorithm.

When jQuery is not present you get $ is undefined
and not your message.
Did you check if you don't have a variable called $ somewhere before your code?
Inspect the value of $ in firebug to see what it is.
Slightly out of the question, but I can't resist to write a shorter code to your class assignment:
var i = 1;
$("ol li").each(function(){
$(this).addClass('olli' + i++);
});
Try the getTimezone and setTimezone, see the example
(But this does use a Class)
UPDATE:
Without any classes you could try something like this:
$the_date = strtotime("2010-01-19 00:00:00");
echo(date_default_timezone_get() . "<br />");
echo(date("Y-d-mTG:i:sz",$the_date) . "<br />");
echo(date_default_timezone_set("UTC") . "<br />");
echo(date("Y-d-mTG:i:sz", $the_date) . "<br />");
NOTE: You might need to set the timezone back to the original as well
Indexing in python starting from 0. You wrote [1:] this would not return you a first char in any case - this will return you a rest(except first char) of string.
If you have the following structure:
mylist = ['base', 'sample', 'test']
And want to get fist char for the first one string(item):
myList[0][0]
>>> b
If all first chars:
[x[0] for x in myList]
>>> ['b', 's', 't']
If you have a text:
text = 'base sample test'
text.split()[0][0]
>>> b
Ive actually managed to get the file picker to appear in Kitkat, to select a image and to get the filepath in activity result but the only thing that im not able to "fix" (cause this workaround) is to make the input filed to fill out with file data.
Does anyone know any way how to access the input-field from a activity ? Am using this example comment. Is just this last piece, the last brick in the wall that i just have to put into right place (tho i could trigger upload of image file directly from code.
Im no hardcore Android dev so i'll show code on newbie level. Im creating a new Activity in already existing Activity

Am creating my BrowseActivity class from this example answer. The WebChromeClient() instance basically looks the same, except last piece, triggering the picker UI part...
private final static int FILECHOOSER_RESULTCODE=1;
private final static int KITKAT_RESULTCODE = 2;
...
// The new WebChromeClient() looks pretty much the same, except one piece...
WebChromeClient chromeClient = new WebChromeClient(){
// For Android 3.0+
public void openFileChooser(ValueCallback<Uri> uploadMsg) { /* Default code */ }
// For Android 3.0+
public void openFileChooser( ValueCallback uploadMsg, String acceptType ) { /* Default code */ }
//For Android 4.1, also default but it'll be as example
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture){
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
BrowseActivity.this.startActivityForResult(Intent.createChooser(i, "File Chooser"), BrowseActivity.FILECHOOSER_RESULTCODE);
}
// The new code
public void showPicker( ValueCallback<Uri> uploadMsg ){
// Here is part of the issue, the uploadMsg is null since it is not triggered from Android
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);

Lastly, the HTML page needs to trigger that new method of showPicker (specificaly when on A4.4)
<form id="form-upload" method="post" enctype="multipart/form-data">
<input id="fileupload" name="fileupload" type="file" onclick="javascript:prepareForPicker();"/>
</form>
<script type="text/javascript">
function getAndroidVersion() {
var ua = navigator.userAgent;
var match = ua.match(/Android\s([0-9\.]*)/);
return match ? match[1] : false;
};
function prepareForPicker(){
if(getAndroidVersion().indexOf("4.4") != -1){
window.jsi.showPicker();
return false;
}
}
function CheckImage(name)
{
//Check to see if user wants to save I used some ajax to save the file if necesarry
}
</script>
For select2 version 4 easily use this:
$('#remote').empty();
After populating select element with ajax call, you may need this line of code in the success section to update the content:
success: function(data, textStatus, jqXHR){
$('#remote').change();
}
Also remember, when running on alternate ports, you need to specify the port on the URL:
There may be firewalls or proxy servers to consider depending on your environment.
<!-- File input (hidden) -->
<input type="file" id="file1" style="display:none"/>
<!-- Trigger button -->
<a href="javascript:void(0)" onClick="openSelect('#file1')">
<script type="text/javascript">
function openSelect(file)
{
$(file).trigger('click');
}
</script>
You can do something like the following these days by referencing the "beforeSubmit" jquery form event. I'm disabling and enabling the submit button to avoid duplicate requests, submitting via ajax, returning a message that's a json array and displaying the information in a pNotify:
jQuery('body').on('beforeSubmit', "#formID", function() {
$('.submitter').prop('disabled', true);
var form = $('#formID');
$.ajax({
url : form.attr('action'),
type : 'post',
data : form.serialize(),
success: function (response)
{
response = jQuery.parseJSON(response);
new PNotify({
text: response.message,
type: response.status,
styling: 'bootstrap3',
delay: 2000,
});
$('.submitter').prop('disabled', false);
},
error : function ()
{
console.log('internal server error');
}
});
});

You can also do like this,
<form method='POST'>
{{form1.as_p}}
<button type="submit" name="btnform1">Save Changes</button>
</form>
<form method='POST'>
{{form2.as_p}}
<button type="submit" name="btnform2">Save Changes</button>
</form>
CODE
if request.method=='POST' and 'btnform1' in request.POST:
do something...
if request.method=='POST' and 'btnform2' in request.POST:
do something...
Any recommendation on how to fix this?
Several. You can use bind:
for (i = 0; i < j; i++) {
asycronouseProcess(function (i) {
alert(i);
}.bind(null, i));
}
Or, if your browser supports let (it will be in the next ECMAScript version, however Firefox already supports it since a while) you could have:
for (i = 0; i < j; i++) {
let k = i;
asycronouseProcess(function() {
alert(k);
});
}
Or, you could do the job of bind
manually (in case the browser doesn't support it, but I would say you can implement a shim in that case, it should be in the link above):
for (i = 0; i < j; i++) {
asycronouseProcess(function(i) {
return function () {
alert(i)
}
}(i));
}
I usually prefer let
when I can use it (e.g. for Firefox add-on); otherwise bind
or a custom currying function (that doesn't need a context object).
I still had a dark grey line after attempting the other answers. I had to add the following two lines to make everything "invisible" in terms of row lines between cells.
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.separatorColor = [UIColor clearColor];
If you use option 2 you are doing a Boolean check which is fast. In option one you are doing a method call (pushing stuff on the stack) and then doing a Boolean check which is still fast. The problem I see is consistency. If some of your debug and info statements are wrapped and some are not it is not a consistent code style. Plus someone later on could change the debug statement to include concatenate strings, which is still pretty fast. I found that when we wrapped out debug and info statement in a large application and profiled it we saved a couple of percentage points in performance. Not much, but enough to make it worth the work. I now have a couple of macros setup in IntelliJ to automatically generate wrapped debug and info statements for me.

To make a robust form, have it load in a useful state and use script to enhance its behaviour. In the following, the select has been replaced by radio buttons (makes life much easier for the user).
The "yes" option is checked by default and the select is enabled. If the user checks either radio button, the select is enabled or disabled accordingly.
<form onclick="this.mySelect1.disabled = this.becomeMember[1].checked;" ... >
<input type="radio" name="becomeMember" checked>Yes<br>
<input type="radio" name="becomeMember">No<br>

The answer by Nils describes how to convert objects to maps, which I found very useful. However, the OP was also wondering where this information is in the MDN docs. While it may not have been there when the question was originally asked, it is now on the MDN page for Object.entries() under the heading Converting an Object to a Map which states:
Converting an Object to a Map
The
new Map()
constructor accepts an iterable ofentries
. WithObject.entries
, you can easily convert fromObject
toMap
:const obj = { foo: 'bar', baz: 42 }; const map = new Map(Object.entries(obj)); console.log(map); // Map { foo: "bar", baz: 42 }
I know this is an old post, but figured I'd share my two cents. @Neji is correct in that you can use sessionStorage.getItem('label')
, and sessionStorage.setItem('label', 'value')
(although he had the setItem
parameters backwards, not a big deal). I much more prefer the following, I think it's more succinct:
var val = sessionStorage.myValue
in place of getItem
and
sessionStorage.myValue = 'value'
in place of setItem
.
Also, it should be noted that in order to store JavaScript objects, they must be stringified to set them, and parsed to get them, like so:
sessionStorage.myObject = JSON.stringify(myObject); //will set object to the stringified myObject
var myObject = JSON.parse(sessionStorage.myObject); //will parse JSON string back to object
The reason is that sessionStorage stores everything as a string, so if you just say sessionStorage.object = myObject
all you get is [object Object], which doesn't help you too much.

Just cast each character to an int:

A little background
Traceview is a graphical viewer for execution logs that you create by using the Debug class to log tracing information in your code. Traceview can help you debug your application and profile its performance. Enabling it creates a .trace
file in the sdcard root folder which can then be extracted by ADB and processed by traceview bat file for processing. It also can get added by the DDMS.
It is a system used internally by the logger. In general unless you are using traceview to extract the trace file this error shouldnt bother you. You should look at error/logs directly related to your application
How do I enable it:
There are two ways to generate trace logs:
Include the Debug class in your code and call its methods such as
startMethodTracing()
andstopMethodTracing()
, to start and stop logging of trace information to disk. This option is very precise because you can specify exactly where to start and stop logging trace data in your code.Use the method profiling feature of DDMS to generate trace logs. This option is less precise because you do not modify code, but rather specify when to start and stop logging with DDMS. Although you have less control on exactly where logging starts and stops, this option is useful if you don't have access to the application's code, or if you do not need precise log timing.
But the following restrictions exist for the above
If you are using the Debug class, your application must have permission to write to external storage (
WRITE_EXTERNAL_STORAGE
).If you are using DDMS: Android 2.1 and earlier devices must have an SD card present and your application must have permission to write to the SD card. Android 2.2 and later devices do not need an SD card. The trace log files are streamed directly to your development machine.
So in essence the traceFile access requires two things
1.) Permission to write a trace log file i.e.
WRITE_EXTERNAL_STORAGE
andREAD_EXTERNAL_STORAGE
for good measure2.) An emulator with an SDCard attached with sufficient space. The doc doesnt say if this is only for DDMS but also for debug, so I am assuming this is also true for debugging via the application.
What do I do with this error:
Now the error is essentially a fall out of either not having the sdcard path to create a tracefile or not having permission to access it. This is an old thread, but the dev behind the bounty, check if are meeting the two prerequisites. You can then go search for the .trace
file in the sdcard folder in your emulator. If it exists it shouldn't be giving you this problem, if it doesnt try creating it by adding the startMethodTracing
to your app.
I'm not sure why it automatically looks for this file when the logger kicks in. I think when an error/log event occurs , the logger internally tries to write to trace file and does not find it, in which case it throws the error.Having scoured through the docs, I don't find too many references to why this is automatically on.
But in general this doesn't affect you directly, you should check direct application logs/errors.
Also as an aside Android 2.2 and later devices do not need an SD card for DDMS trace logging. The trace log files are streamed directly to your development machine.
Additional information on Traceview:
Copying Trace Files to a Host Machine
After your application has run and the system has created your trace files .trace on a device or emulator, you must copy those files to your development computer. You can use adb pull to copy the files. Here's an example that shows how to copy an example file, calc.trace, from the default location on the emulator to the /tmp directory on the emulator host machine:
adb pull /sdcard/calc.trace /tmp Viewing Trace Files in Traceview To run Traceview and view the trace files, enter traceview . For example, to run Traceview on the example files copied in the previous section, use:
traceview /tmp/calc Note: If you are trying to view the trace logs of an application that is built with ProGuard enabled (release mode build), some method and member names might be obfuscated. You can use the Proguard mapping.txt file to figure out the original unobfuscated names. For more information on this file, see the Proguard documentation.
I think any other answer regarding positioning of oncreate
statements or removing uses-sdk
are not related, but this is Android and I could be wrong. Would be useful to redirect this question to an android engineer or post it as a bug

I'm using Eclipse and I copied your code and got the same error. I then opened up the project properties->Java Build Path -> Libraries->Add External JARs... c:\jrun4\lib\sqlitejdbc-v056.jar Worked like a charm. You may need to restart your web server if you've just copied the .jar file.

To add a header just add the following code to the location block where you want to add the header:
location some-location {
add_header X-my-header my-header-content;
}
Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.
Use an array, not a string, as given as guidance in BashFAQ #50.
Using a string is extremely bad security practice: Consider the case where password
(or a where clause in the query, or any other component) is user-provided; you don't want to eval
a password containing $(rm -rf .)
!

How about some Regex?
I wrote this for a text a file, but I believe this could work for you
(In case your text file contains line starting exactly with the "matched" ones below - simply adapt your Regex)
private static List<string> fileUploadRequestParser(Stream stream)
{
//-----------------------------111111111111111
//Content-Disposition: form-data; name="file"; filename="data.txt"
//Content-Type: text/plain
//...
//...
//-----------------------------111111111111111
//Content-Disposition: form-data; name="submit"
//Submit
//-----------------------------111111111111111--
List<String> lstLines = new List<string>();
TextReader textReader = new StreamReader(stream);
string sLine = textReader.ReadLine();
Regex regex = new Regex("(^-+)|(^content-)|(^$)|(^submit)", RegexOptions.IgnoreCase | RegexOptions.Compiled | RegexOptions.Singleline);
while (sLine != null)
{
if (!regex.Match(sLine).Success)
{
lstLines.Add(sLine);
}
sLine = textReader.ReadLine();
}
return lstLines;
}
/^(one|two|tree)$/i.test(field) // field = Two; // true
/^(one|two|tree)$/i.test(field) // field = six; // false
/^(???|???|???)$/ui.test(field) // field = ???; // true
This is useful for checking dynamic variables. This method is easy to read.
Well i just want to add that even if sometimes they are necessary for the encapsulation and security of your variables/objects, if we want to code a real Object Oriented Program, then we need to STOP OVERUSING THE ACCESSORS, cause sometimes we depend a lot on them when is not really necessary and that makes almost the same as if we put the variables public.
the accepted answer is not correct, and it makes no sens to accept it considering the question

I have just compile it and it compiles fine without the implicit import, probably you're seeing a stale cache or something of your IDE.
Have you tried compiling from the command line?
I have the exact same version:
Probably you're thinking the warning is an error.
UPDATE
It looks like you have a Arrays.class
file in the directory where you're trying to compile ( probably created before ). That's why the explicit import solves the problem. Try copying your source code to a clean new directory and try again. You'll see there is no error this time. Or, clean up your working directory and remove the Arrays.class
A "u" prefix denotes the value has type unicode
rather than str
.
Raw string literals, with an "r" prefix, escape any escape sequences within them, so len(r"\n")
is 2. Because they escape escape sequences, you cannot end a string literal with a single backslash: that's not a valid escape sequence (e.g. r"\"
).
"Raw" is not part of the type, it's merely one way to represent the value. For example, "\\n"
and r"\n"
are identical values, just like 32
, 0x20
, and 0b100000
are identical.
You can have unicode raw string literals:
>>> u = ur"\n"
>>> print type(u), len(u)
<type 'unicode'> 2
The source file encoding just determines how to interpret the source file, it doesn't affect expressions or types otherwise. However, it's recommended to avoid code where an encoding other than ASCII would change the meaning:
Files using ASCII (or UTF-8, for Python 3.0) should not have a coding cookie. Latin-1 (or UTF-8) should only be used when a comment or docstring needs to mention an author name that requires Latin-1; otherwise, using \x, \u or \U escapes is the preferred way to include non-ASCII data in string literals.
Use file
. Examples:
> file --mime-type image.png
image.png: image/png
> file -b --mime-type image.png
image/png
> file -i FILE_NAME
image.png: image/png; charset=binary
What to do if :foo
in its natural form contains slashes? You wouldn't want it to Isn't that the distinction the recommendation is attempting to preserve? It specifically notes,
The similarity to unix and other disk operating system filename conventions should be taken as purely coincidental, and should not be taken to indicate that URIs should be interpreted as file names.
If one was building an online interface to a backup program, and wished to express the path as a part of the URL path, it would make sense to encode the slashes in the file path, as that is not really part of the hierarchy of the resource - and more importantly, the route. /backups/2016-07-28content//home/dan/
loses the root of the filesystem in the double slash. Escaping the slashes is the appropriate way to distinguish, as I read it.
I believe fcntl()
is a POSIX function. Where as ioctl()
is a standard UNIX thing. Here is a list of POSIX io. ioctl()
is a very kernel/driver/OS specific thing, but i am sure what you use works on most flavors of Unix. some other ioctl()
stuff might only work on certain OS or even certain revs of it's kernel.

Mockito alone is not the best solution for handling exceptions, use Mockito with Catch-Exception
given(otherServiceMock.bar()).willThrow(new MyException());
when(() -> myService.foo());
then(caughtException()).isInstanceOf(MyException.class);
It work's using rules
instead of loaders

Sometimes using row.getLastCellNum()
gives you a higher value than what is actually filled in the file.
I used the method below to get the last column index that contains an actual value.
private int getLastFilledCellPosition(Row row) {
int columnIndex = -1;
for (int i = row.getLastCellNum() - 1; i >= 0; i--) {
Cell cell = row.getCell(i);
if (cell == null || CellType.BLANK.equals(cell.getCellType()) || StringUtils.isBlank(cell.getStringCellValue())) {
continue;
} else {
columnIndex = cell.getColumnIndex();
break;
}
}
return columnIndex;
}
I'm using flow with vscode but had the same problem. I solved it with these steps:

Disable the built-in TypeScript extension:
You need to do something like this:
// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");
// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");
// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
// grab the "id" attribute
XmlAttribute idAttribute = aNode.Attributes["id"];
// check if that attribute even exists...
if (idAttribute != null)
{
// if yes - read its current value
string currentValue = idAttribute.Value;
// here, you can now decide what to do - for demo purposes,
// I just set the ID value to a fixed value if it was empty before
if (string.IsNullOrEmpty(currentValue))
{
idAttribute.Value = "515";
}
}
}
// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");
Expanding on @zfy explanation... The equation for one input, one neuron, one output should look:
y = a * x + b * 1 and out = f(y)
where x is the value from the input node and 1 is the value of the bias node; y can be directly your output or be passed into a function, often a sigmoid function. Also note that the bias could be any constant, but to make everything simpler we always pick 1 (and probably that's so common that @zfy did it without showing & explaining it).
Your network is trying to learn coefficients a and b to adapt to your data.
So you can see why adding the element b * 1
allows it to fit better to more data: now you can change both slope and intercept.
If you have more than one input your equation will look like:
y = a0 * x0 + a1 * x1 + ... + aN * 1
Note that the equation still describes a one neuron, one output network; if you have more neurons you just add one dimension to the coefficient matrix, to multiplex the inputs to all nodes and sum back each node contribution.
That you can write in vectorized format as
A = [a0, a1, .., aN] , X = [x0, x1, ..., 1]
Y = A . XT
i.e. putting coefficients in one array and (inputs + bias) in another you have your desired solution as the dot product of the two vectors (you need to transpose X for the shape to be correct, I wrote XT a 'X transposed')
So in the end you can also see your bias as is just one more input to represent the part of the output that is actually independent of your input.
Heard you can do this in postman:
In your IntelliJ idea find tools.jar replace it with tools.jar from yout JDK8
If you are using the codeigniter framework and are testing the project on a localhost, open the main Index.php file of your project folder and find this code:
define('ENVIRONMENT', 'production');
Change it to
define ('ENVIRONMENT', 'development');
Because same this ENVIRONMENT is in your database.php file under config folder. like this:
'db_debug' => (ENVIRONMENT! == 'development')
So the environment should be the same in both places and problem will be solved.

If you only want to check for the presence of abc
in any string in the list, you could try
some_list = ['abc-123', 'def-456', 'ghi-789', 'abc-456']
if any("abc" in s for s in some_list):
# whatever
If you really want to get all the items containing abc
, use
matching = [s for s in some_list if "abc" in s]
None of these suggestions were working for me. I finally found something else I could do - dbms_output.put_line
. For example:
SET SERVEROUTPUT ON
begin
for i in (select dbms_metadata.get_ddl('INDEX', index_name, owner) as ddl from all_indexes where owner = 'MYUSER') loop
dbms_output.put_line(i.ddl);
end loop;
end;
/
Boom. It printed out everything I wanted - no truncating or anything like that. And that works straight in sqlplus
- no need to put it in a separate file or anything.

I had a similar issue except the "Server Name" field was disabled.
Found this was due to the Apache Tomcat v7.0 runtime environment pointing to the wrong folder. This was fixed by going to Window - Preferences - Server - Runtime Environments, clicking on the runtime environment entry and clicking "Edit..." and then modifying the Tomcat installation directory.

When you use $.getJSON on an external domain it automatically actions a JSONP request, for example my tweet slider here
If you look at the source code you can see that I am calling the Twitter API using .getJSON.
So your example would be: THIS IS TESTED AND WORKS (You can go to http://smallcoders.com/javascriptdevenvironment.html to see it in action)
//JAVASCRIPT
$.getJSON('http://www.write-about-property.com/jsonp.php?callback=?','firstname=Jeff',function(res){
alert('Your name is '+res.fullname);
});
//SERVER SIDE
<?php
$fname = $_GET['firstname'];
if($fname=='Jeff')
{
//header("Content-Type: application/json");
echo $_GET['callback'] . '(' . "{'fullname' : 'Jeff Hansen'}" . ')';
}
?>
Note the ?callback=? and +res.fullname
In VB it's:

but this should help.
Faced with the same issue, supporting older devices via the deprecated camera API and needing the new Camera2 API for both current devices and moving into the future; I ran into the same issues -- and have not found a 3rd party library that bridges the 2 APIs, likely because they are very different, I turned to basic OOP principals.
The 2 APIs are markedly different making interchanging them problematic for client objects expecting the interfaces presented in the old API. The new API has different objects with different methods, built using a different architecture. Got love for Google, but ragnabbit! that's frustrating.
So I created an interface focussing on only the camera functionality my app needs, and created a simple wrapper for both APIs that implements that interface. That way my camera activity doesn't have to care about which platform its running on...
I also set up a Singleton to manage the API(s); instancing the older API's wrapper with my interface for older Android OS devices, and the new API's wrapper class for newer devices using the new API. The singleton has typical code to get the API level and then instances the correct object.
The same interface is used by both wrapper classes, so it doesn't matter if the App runs on Jellybean or Marshmallow--as long as the interface provides my app with what it needs from either Camera API, using the same method signatures; the camera runs in the App the same way for both newer and older versions of Android.
The Singleton can also do some related things not tied to the APIs--like detecting that there is indeed a camera on the device, and saving to the media library.
I hope the idea helps you out.
It's obvious, but the App Theme
selection in design is just for display a draft during layout edition, is not related to real app looking in cell phone. In my case, there is no title bar in design but the title bar was always in cell phone.
I'm starting with Android programming and fight to discover a right solution.
Just change the manifest file (AndroidManifest.xml
) is not enough because the style need to be predefined is styles.xml
. Also is useless change the layout files.
All proposed solution in Java
or Kotlin
has failed for me. Some of them crash the app. And if one never (like me) intend to use the title bar in app, the static solution is cleaner.
For me the only solution that works in 2019 (Android Studio 3.4.1) is:
in styles.xml
(under app/res/values) add the lines:
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
After in AndroidManifest.xml
(under app/manifests)
Replace
android:theme="@style/AppTheme">
by
android:theme="@style/AppTheme.NoActionBar">
You can't set a minimum length on a text field. Otherwise, users wouldn't be able to type in the first five characters.
Your best bet is to validate the input when the form is submitted to ensure that the length is six.
maxlength is not a validation attribute. It is designed to prevent the user from physically typing in more than six characters. The corresponding minlengh is not in scope of the HTML specification, because its implementation would render the textbox unusable.
I was trying some of the solutions here but then I actually came up with my own one. I hope this might be useful for the next one so I share it here:
def sort_correlation_matrix(correlation_matrix):
cor = correlation_matrix.abs()
top_col = cor[cor.columns[0]][1:]
top_col = top_col.sort_values(ascending=False)
ordered_columns = [cor.columns[0]] + top_col.index.tolist()
return correlation_matrix[ordered_columns].reindex(ordered_columns)
I sorted this problem as verifying the json from JSONLint.com and then, correcting it. And this is code for the same.
String jsonStr = "[{\r\n" + "\"name\":\"New York\",\r\n" + "\"number\": \"732921\",\r\n"+ "\"center\": {\r\n" + "\"latitude\": 38.895111,\r\n" + " \"longitude\": -77.036667\r\n" + "}\r\n" + "},\r\n" + " {\r\n"+ "\"name\": \"San Francisco\",\r\n" +\"number\":\"298732\",\r\n"+ "\"center\": {\r\n" + " \"latitude\": 37.783333,\r\n"+ "\"longitude\": -122.416667\r\n" + "}\r\n" + "}\r\n" + "]";
ObjectMapper mapper = new ObjectMapper();
MyPojo[] jsonObj = mapper.readValue(jsonStr, MyPojo[].class);
for (MyPojo itr : jsonObj) {
System.out.println("Val of name is: " + itr.getName());
System.out.println("Val of number is: " + itr.getNumber());
System.out.println("Val of latitude is: " +
itr.getCenter().getLatitude());
System.out.println("Val of longitude is: " +
itr.getCenter().getLongitude() + "\n");
}
Note: MyPojo[].class
is the class having getter and setter of json properties.
Result:
Val of name is: New York
Val of number is: 732921
Val of latitude is: 38.895111
Val of longitude is: -77.036667
Val of name is: San Francisco
Val of number is: 298732
Val of latitude is: 37.783333
Val of longitude is: -122.416667
You're doing something wrong (probably too small read buffer). On a machine of undecent age (Athlon 2x1800MP from 2002) that has DMA on disk probably out of whack (6.6M/s is damn slow when doing sequential reads):
Create a 1G file with "random" data:
# dd if=/dev/sdb of=temp.dat bs=1M count=1024
1073741824 bytes (1.1 GB) copied, 161.698 s, 6.6 MB/s
# time sha1sum -b temp.dat
abb88a0081f5db999d0701de2117d2cb21d192a2 *temp.dat
1m5.299s
# time md5sum -b temp.dat
9995e1c1a704f9c1eb6ca11e7ecb7276 *temp.dat
1m58.832s
This is also weird, md5 is consistently slower than sha1 for me (reran several times).
A class is an element in object oriented programming that aggregates attributes(fields) - which can be public accessible or not - and methods(functions) - which also can be public or private and usually writes/reads those attributes.
so you can have a class like Array
with a public attribute length
and a public method sort()
.
<?php
echo "<pre>";
print_r(get_loaded_extensions());
echo "<pre/>";
?>
You can also search for the file. Navigate to your project directory with PowerShell and run Get-FileMissingRoot:
function Get-FileMissingRoot {
dir -recurse |
where {
($_ -is [IO.FileInfo]) -and
(@(".xml", ".config") -contains $_.extension)
} |
foreach {
$xml = New-Object Xml.XmlDocument;
$filename = $_.FullName
try {
$xml.Load($filename)
}
catch {
write ("File: " + $filename)
write ($_.Exception.Message)
}
}
}
The issue could be that Github isn't present in your ~/.ssh/known_hosts file.
Append GitHub to the list of authorized hosts:
ssh-keyscan -H github.com >> ~/.ssh/known_hosts
The way you are doing it is indeed the recommended one (for Python 2.x).
The issue of whether the class is passed explicitly to super
is a matter of style rather than functionality. Passing the class to super
fits in with Python's philosophy of "explicit is better than implicit".
If you want to list them all in a nice list but without using the cruddy non human friendly name, you can do this...
object.errors.each do |attr,message|
puts "<li>"+message+"</li>"
end
There is no any problem to write multiple lines of execution withing a single try catch block like below
try{
install_engine();
install_break();
}
catch(Exception $e){
show_exception($e->getMessage());
}
The moment any execption occure either in install_engine
or install_break
function the control will be passed to catch function.
One more recommendation is to eat your exception properly. Which means instead of writing die('Message')
it is always advisable to have exception process properly. You may think of using die()
function in error handling but not in exception handling.
When you should use multiple try catch block You can think about multiple try catch block if you want the different code block exception to display different type of exception or you are trying to throw any exception from your catch block like below:
try{
install_engine();
install_break();
}
catch(Exception $e){
show_exception($e->getMessage());
}
try{
install_body();
paint_body();
install_interiour();
}
catch(Exception $e){
throw new exception('Body Makeover faield')
}
For people who find this when attempting to run tests because via npm test
or ng test
using Karma or whatever else. Your .spec module needs a special router testing import to be able to build.

The least generic way I found to do this with Regex and Pattern / Matcher classes:
String text = "test string (67)";
String START = "\\("; // A literal "(" character in regex
String END = "\\)"; // A literal ")" character in regex
// Captures the word(s) between the above two character(s)
String pattern = START + "(\w+)" + END;
Pattern pattern = Pattern.compile(pattern);
Matcher matcher = pattern.matcher(text);
while(matcher.find()) {
System.out.println(matcher.group()
.replace(START, "").replace(END, ""));
}
This may help for more complex regex problems where you want to get the text between two set of characters.
datetime.datetime.fromtimestamp()
is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp()
expects Unix timestamp, in seconds.
Do it like that:
>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)
and the result is:
>>> date
datetime.datetime(2012, 3, 16, 1, 0)
Does it answer your question?
EDIT: J.F. Sebastian correctly suggested to use true division by 1e3
(float 1000
). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int
when dividing (using /
operator) int
by int
(this is called floor division). By replacing the divisor 1000
(being an int
) with the 1e3
divisor (being representation of 1000
as float) or with float(1000)
(or 1000.
etc.), the division becomes true division. Python 2.x returns float
when dividing int
by float
, float
by int
, float
by float
etc. And when there is some fractional part in the timestamp passed to fromtimestamp()
method, this method's result also contains information about that fractional part (as the number of microseconds).
You can create a custom decorator to add to your component to make it aware of enums.
export enum MyEnum {
FirstValue,
SecondValue
}
import { MyEnum } from './myenum.enum';
export function MyEnumAware(constructor: Function) {
constructor.prototype.MyEnum = MyEnum;
}
import { Component } from '@angular2/core';
import { MyEnum } from './myenum.enum';
import { MyEnumAware } from './myenumaware.decorator';
@Component({
selector: 'enum-aware',
template: `
<div [ngSwitch]="myEnumValue">
<div *ngSwitchCase="MyEnum.FirstValue">
First Value
</div>
<div *ngSwitchCase="MyEnum.SecondValue">
Second Value
</div>
</div>
<button (click)="toggleValue()">Toggle Value</button>
`,
})
@MyEnumAware // <---------------!!!
export default class EnumAwareComponent {
myEnumValue: MyEnum = MyEnum.FirstValue;
toggleValue() {
this.myEnumValue = this.myEnumValue === MyEnum.FirstValue
? MyEnum.SecondValue : MyEnum.FirstValue;
}
}
Remove "values" when you're appending a group of rows, and remove the extra parentheses. You can avoid the circular reference by using an alias for avg(CurrencyColumn) (as you did in your example) or by not using an alias at all.
If the column names are the same in both tables, your query would be like this:
INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn) as CurrencyColumn1
FROM Table1
GROUP BY LongIntColumn;
And it would work without an alias:
INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn)
FROM Table1
GROUP BY LongIntColumn;
You can also use freely Application.StartupPath from System.Windows.Forms, but you must to add reference for System.Windows.Forms assembly!
You're looking for a shuffling algorithm, right?
Okay, there are two ways to do this: the clever-but-people-always-seem-to-misunderstand-it-and-get-it-wrong-so-maybe-its-not-that-clever-after-all way, and the dumb-as-rocks-but-who-cares-because-it-works way.
- Create a duplicate of your first array, but tag each string should with a random number.
- Sort the duplicate array with respect to the random number.
This algorithm works well, but make sure that your random number generator is unlikely to tag two strings with the same number. Because of the so-called Birthday Paradox, this happens more often than you might expect. Its time complexity is O(n log n).
I'll describe this as a recursive algorithm:
To shuffle an array of size n (indices in the range [0..n-1]):
if n = 0if n > 0
- do nothing
- (recursive step) shuffle the first n-1 elements of the array
- choose a random index, x, in the range [0..n-1]
- swap the element at index n-1 with the element at index x
The iterative equivalent is to walk an iterator through the array, swapping with random elements as you go along, but notice that you cannot swap with an element after the one that the iterator points to. This is a very common mistake, and leads to a biased shuffle.
Time complexity is O(n).
Install new version of Dev c++. It works fine in Windows 8. It also supports 64 bit version.

Function convert image to base64 using jquery (you can convert to vanila js). Hope it help to you!
Usage: input is your nameId input has file image
<input type="file" id="asd"/>
<button onclick="proccessData()">Submit</button>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
async function converImageToBase64(inputId) {
let image = $('#'+inputId)[0]['files']
if (image && image[0]) {
const reader = new FileReader();
return new Promise(resolve => {
reader.onload = ev => {
resolve(ev.target.result)
}
reader.readAsDataURL(image[0])
})
}
}
async function proccessData() {
const image = await converImageToBase64('asd')
console.log(image)
}
</script>
Example: converImageToBase64('yourFileInputId')
You can use XDocument.Parse
for this.
The value_type
of a map
is a pair
containing the key and value as it's first
and second
member, respectively.
map<string, int>::iterator it;
for (it = symbolTable.begin(); it != symbolTable.end(); it++)
{
std::cout << it->first << ' ' << it->second << '\n';
}
Or with C++11, using range-based for:
for (auto const& p : symbolTable)
{
std::cout << p.first << ' ' << p.second << '\n';
}
In the event that you need to do this with JSON:
=CONCATENATE("'{""service"": { ""field"": "&A2&"}}'")
Use this :
private string GetAlbumRSS(SyndicationItem album)
{
string url = "";
foreach (SyndicationElementExtension ext in album.ElementExtensions)
if (ext.OuterName == "itemRSS") url = ext.GetObject<string>();
return (url);
}
protected void Page_Load(object sender, EventArgs e)
{
string albumRSS;
string url = "http://www.SomeSite.com/rss?";
XmlReader r = XmlReader.Create(url);
SyndicationFeed albums = SyndicationFeed.Load(r);
r.Close();
foreach (SyndicationItem album in albums.Items)
{
cell.InnerHtml = cell.InnerHtml +string.Format("<br \'><a href='{0}'>{1}</a>", album.Links[0].Uri, album.Title.Text);
albumRSS = GetAlbumRSS(album);
}
}
To add to Oleg's answer:
I was able to find the DLL at runtime by appending Visual Studio's $(ExecutablePath)
to the PATH environment variable in Configuration Properties->Debugging. This macro is exactly what's defined in the Configuration Properties->VC++ Directories->Executable Directories field*, so if you have that setup to point to any DLLs you need, simply adding this to your PATH makes finding the DLLs at runtime easy!
* I actually don't know if the $(ExecutablePath)
macro uses the project's Executable Directories setting or the global Property Pages' Executable Directories setting. Since I have all of my libraries that I often use configured through the Property Pages, these directories show up as defaults for any new projects I create.
tl;dr
cp -R "/src/project 1/App" "/src/project 2"
Explanation:
Using quotes will cater for spaces in the directory names
cp -R "/src/project 1/App" "/src/project 2"
If the App directory is specified in the destination directory:
cp -R "/src/project 1/App" "/src/project 2/App"
and "/src/project 2/App" already exists the result will be "/src/project 2/App/App"
Best not to specify the directory copied in the destination so that the command can be repeated over and over with the expected result.
Inside a bash script:
cp -R "${1}/App" "${2}"
Had the same issue. Permission denied (publickey) when trying to login in with 'ec2-user' or with 'root'.
Googled the AMI number of the machine image and it had the SSH login information right their on the Debian wiki page.
Hope this helps.
I have toyed with this for forever, and finally found something that seems to always work!
textField = new JTextField() {
public void addNotify() {
super.addNotify();
requestFocus();
}
};
From the documentation:
str.find(sub[, start[, end]])
Return the lowest index in the string where substring sub is found within the slice
s[start:end]
. Optional arguments start and end are interpreted as in slice notation. Return-1
if sub is not found.
So, some examples:
>>> my_str = 'abcdefioshgoihgs sijsiojs '
>>> my_str.find('a')
0
>>> my_str.find('g')
10
>>> my_str.find('s', 11)
15
>>> my_str.find('s', 15)
15
>>> my_str.find('s', 16)
17
>>> my_str.find('s', 11, 14)

The git blame
command is used to know who/which commit is responsible for the latest changes made to a file. The author/commit of each line can also been seen.
git blame filename
(commits responsible for changes for all lines in code)
git blame filename -L 0,10
(commits responsible for changes from line "0" to line "10")
There are many other options for blame, but generally these could help.
