In windows, If the user is using your script locally, it will be very simple :
<?php
// get all the informations about the client's network
$ipconfig = shell_exec ("ipconfig/all"));
// display those informations
echo $ipconfig;
/*
look for the value of "physical adress" and use substr() function to
retrieve the adress from this long string.
here in my case i'm using a french cmd.
you can change the numbers according adress mac position in the string.
*/
echo substr(shell_exec ("ipconfig/all"),1821,18);
?>
As with regular parameters, declaring an optional parameter is just a matter of the path property of a Route; any parameter that ends with a question mark will be treated as optional:
<Route path="to/page/:pathParam?" component={MyPage}/>
Using $_SERVER['HTTP_REFERER']
The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.
if (!empty($_SERVER['HTTP_REFERER'])) {
header("Location: " . $_SERVER['HTTP_REFERER']);
} else {
header("Location: index.php");
}
exit;
Use IList<IWebElement>
instead of List<IWebElement>
.
For instance:
IList<IWebElement> options = elem.FindElements(By.TagName("option"));
foreach (IWebElement option in options)
{
Console.WriteLine(option.Text);
}

Set up a flux container
simple example
import alt from './../../alt.js';
class PostActions {
constructor(){
this.generateActions('setMessages');
}
setMessages(indexArray){
this.actions.setMessages(indexArray);
}
}
export default alt.createActions(PostActions);
store looks like this
class PostStore{
constructor(){
this.messages = [];
this.bindActions(MessageActions);
}
setMessages(messages){
this.messages = messages;
}
}
export default alt.createStore(PostStore);
Then every component that listens to the store can share this variable In your constructor is where you should grab it
constructor(props){
super(props);
//here is your data you get from the store, do what you want with it
var messageStore = MessageStore.getState();
}
componentDidMount() {
MessageStore.listen(this.onMessageChange.bind(this));
}
componentWillUnmount() {
MessageStore.unlisten(this.onMessageChange.bind(this));
}
onMessageChange(state){
//if the data ever changes each component listining will be notified and can do the proper processing.
}
This way, you can share you data across the app without every component having to communicate with each other.
This has been already answered but I tried a different way to make it simpler.
The idea is using putting an ImageButton
on the right of EditText
and having negative margin to it so that the EditText
flows into the ImageButton
making it look like the Button is in the EditText
.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:id="@+id/editText"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="Enter Pin"
android:singleLine="true"
android:textSize="25sp"
android:paddingRight="60dp"
/>
<ImageButton
android:id="@+id/pastePin"
android:layout_marginLeft="-60dp"
style="?android:buttonBarButtonStyle"
android:paddingBottom="5dp"
android:src="@drawable/ic_action_paste"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
Also, as shown above, you can use a paddingRight
of similar width in the EditText
if you don't want the text in it to be flown over the ImageButton
.
I guessed margin size with the help of android-studio's layout designer and it looks similar across all screen sizes. Or else you can calculate the width of the ImageButton
and set the margin programatically.
If you are interested in finding any file type by their magic bytes using the awesome file
utility combined with power of find
, this can come in handy:
$ # Let's make some test files
$ mkdir ASCII-finder
$ cd ASCII-finder
$ dd if=/dev/urandom of=binary.file bs=1M count=1
1+0 records in
1+0 records out
1048576 bytes (1.0 MB, 1.0 MiB) copied, 0.009023 s, 116 MB/s
$ file binary.file
binary.file: data
$ echo 123 > text.txt
$ # Let the magic begin
$ find -type f -print0 | \
xargs -0 -I @@ bash -c 'file "$@" | grep ASCII &>/dev/null && echo "file is ASCII: $@"' -- @@
Output:
file is ASCII: ./text.txt
Legend: $
is the interactive shell prompt where we enter our commands
You can modify the part after &&
to call some other script or do some other stuff inline as well, i.e. if that file contains given string, cat the entire file or look for a secondary string in it.
Explanation:
find
items that are filesxargs
feed each item as a line into one liner bash
command/scriptfile
checks type of file by magic byte, grep
checks if ASCII
exists, if so, then after &&
your next command executes.find
prints results null
separated, this is good to escape
filenames with spaces and meta-characters in it.xargs
, using -0
option, reads them null
separated, -I @@
takes each record and uses as positional parameter/args to bash
script.--
for bash
ensures whatever comes after it is an argument even
if it starts with -
like -c
which could otherwise be interpreted
as bash optionIf you need to find types other than ASCII, simply replace grep ASCII
with other type, like grep "PDF document, version 1.4"
You can write a simple helper function for it. Lodash has a similar function with the same name: omit
function omit(obj, omitKey) {
return Object.keys(obj).reduce((result, key) => {
if(key !== omitKey) {
result[key] = obj[key];
}
return result;
}, {});
}
omit({a: 1, b: 2, c: 3}, 'c') // {a: 1, b: 2}
Also, note that it is faster than Object.assign and delete then: http://jsperf.com/omit-key
You'll want to use the process.argv
array to access the command-line arguments to get the filename and the FileSystem module (fs) to read the file. For example:
// Make sure we got a filename on the command line.
if (process.argv.length < 3) {
console.log('Usage: node ' + process.argv[1] + ' FILENAME');
process.exit(1);
}
// Read the file and print its contents.
var fs = require('fs')
, filename = process.argv[2];
fs.readFile(filename, 'utf8', function(err, data) {
if (err) throw err;
console.log('OK: ' + filename);
console.log(data)
});
To break that down a little for you process.argv
will usually have length two, the zeroth item being the "node" interpreter and the first being the script that node is currently running, items after that were passed on the command line. Once you've pulled a filename from argv then you can use the filesystem functions to read the file and do whatever you want with its contents. Sample usage would look like this:
$ node ./cat.js file.txt
OK: file.txt
This is file.txt!
[Edit] As @wtfcoder mentions, using the "fs.readFile()
" method might not be the best idea because it will buffer the entire contents of the file before yielding it to the callback function. This buffering could potentially use lots of memory but, more importantly, it does not take advantage of one of the core features of node.js - asynchronous, evented I/O.
The "node" way to process a large file (or any file, really) would be to use fs.read()
and process each available chunk as it is available from the operating system. However, reading the file as such requires you to do your own (possibly) incremental parsing/processing of the file and some amount of buffering might be inevitable.
Many way to Json Parse but i have found most effective way to
@model List<string[]>
<script>
function DataParse() {
var model = '@Html.Raw(Json.Encode(Model))';
var data = JSON.parse(model);
for (i = 0; i < data.length; i++) {
......
}
</script>
There are several problems in your code.
First the big ones:
You are creating a new figure and a new axes in every iteration of your loop ?
put fig = plt.figure
and ax = fig.add_subplot(1,1,1)
outside of the loop.
Don't use the Locators. Call the functions ax.set_xticks()
and ax.grid()
with the correct keywords.
With plt.axes()
you are creating a new axes again. Use ax.set_aspect('equal')
.
The minor things:
You should not mix the MATLAB-like syntax like plt.axis()
with the objective syntax.
Use ax.set_xlim(a,b)
and ax.set_ylim(a,b)
This should be a working minimal example:
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
# Major ticks every 20, minor ticks every 5
major_ticks = np.arange(0, 101, 20)
minor_ticks = np.arange(0, 101, 5)
ax.set_xticks(major_ticks)
ax.set_xticks(minor_ticks, minor=True)
ax.set_yticks(major_ticks)
ax.set_yticks(minor_ticks, minor=True)
# And a corresponding grid
ax.grid(which='both')
# Or if you want different settings for the grids:
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)
plt.show()
Output is this:
You cannot in pure CSS. Having an image covering the whole page behind all other components is probably your best bet (looks like that's the solution given above). Anyway, chances are it will look awful anyway. I would try either an image big enough to cover most screen resolutions (say up to 1600x1200, above it is scarcer), to limit the width of the page, or just to use an image that tile.
Now require-dev
is enabled by default, for local development you can do composer install
and composer update
without the --dev
option.
When you want to deploy to production, you'll need to make sure composer.lock
doesn't have any packages that came from require-dev
.
You can do this with
composer update --no-dev
Once you've tested locally with --no-dev
you can deploy everything to production and install based on the composer.lock
. You need the --no-dev
option again here, otherwise composer will say "The lock file does not contain require-dev information".
composer install --no-dev
Note: Be careful with anything that has the potential to introduce differences between dev and production! I generally try to avoid require-dev wherever possible, as including dev tools isn't a big overhead.
Save it to the same variable
data["column01"].where(data["column01"]< 5, inplace=True)
Save it to a separate variable
data["column02"] = data["column01"].where(data["column1"]< 5)
But, you can always overwrite the variable
data["column01"] = data["column01"].where(data["column1"]< 5)
FYI: In default inplace = False
What missing for me was I was using
import { Router, Route, browserHistory, IndexRoute } from 'react-router';
instead or correct answer should be :
import { BrowserRouter as Router, Route } from 'react-router-dom';
Ofcourse you need to add npm package react-router-dom:
npm install react-router-dom@next --save
You can use cluster module. Check this.
var cluster = require('cluster');
var http = require('http');
var numCPUs = require('os').cpus().length;
if (cluster.isMaster) {
// Fork workers.
for (var i = 0; i < numCPUs; i++) {
cluster.fork();
}
cluster.on('exit', function(worker, code, signal) {
console.log('worker ' + worker.process.pid + ' died');
});
} else {
// Workers can share any TCP connection
// In this case its a HTTP server
http.createServer(function(req, res) {
res.writeHead(200);
res.end("hello world\n");
}).listen(8000);
}

After Spring Boot 2, a lot has changed. The above given answers work prior to Spring Boot 2. Now if you are running your application with runtime arguments for the server port, then you will only get the static value with @Value("${server.port}")
, that is mentioned in the application.properties file. Now to get the actual port in which the server is running, use the following method:
@Autowired
private ServletWebServerApplicationContext server;
@GetMapping("/server-port")
public String serverPort() {
return "" + server.getWebServer().getPort();
}
Also, if you are using your applications as Eureka/Discovery Clients with load balanced RestTemplate
or WebClient
, the above method will return the exact port number.
you can use wc to count the number of characters in the file wc -m filename.txt. Hope that help.
You have probably defined $name
, $date
, $text
or $date2
to be a string, like:
$name = 'String';
Then if you treat it like an array it will give that fatal error:
$name[] = 'new value'; // fatal error
To solve your problem just add the following code at the beginning of the loop:
$name = array();
$date = array();
$text = array();
$date2 = array();
This will reset their value to array and then you'll able to use them as arrays.
I don't understand why people are willing to work so hard to find a pure-CSS solution for simple columnar layouts that are SO EASY using the old TABLE

All Browsers still have the table layout logic... Call me a dinosaur perhaps, but I say let it help you.

It takes keyword arguments for the variables:
url_for('add', variable=foo)
A Y-combinator is a "functional" (a function that operates on other functions) that enables recursion, when you can't refer to the function from within itself. In computer-science theory, it generalizes recursion, abstracting its implementation, and thereby separating it from the actual work of the function in question. The benefit of not needing a compile-time name for the recursive function is sort of a bonus. =)
This is applicable in languages that support lambda functions. The expression-based nature of lambdas usually means that they cannot refer to themselves by name. And working around this by way of declaring the variable, refering to it, then assigning the lambda to it, to complete the self-reference loop, is brittle. The lambda variable can be copied, and the original variable re-assigned, which breaks the self-reference.
Y-combinators are cumbersome to implement, and often to use, in static-typed languages (which procedural languages often are), because usually typing restrictions require the number of arguments for the function in question to be known at compile time. This means that a y-combinator must be written for any argument count that one needs to use.
Below is an example of how the usage and working of a Y-Combinator, in C#.
Using a Y-combinator involves an "unusual" way of constructing a recursive function. First you must write your function as a piece of code that calls a pre-existing function, rather than itself:
// Factorial, if func does the same thing as this bit of code...
x == 0 ? 1: x * func(x - 1);
Then you turn that into a function that takes a function to call, and returns a function that does so. This is called a functional, because it takes one function, and performs an operation with it that results in another function.
// A function that creates a factorial, but only if you pass in
// a function that does what the inner function is doing.
Func<Func<Double, Double>, Func<Double, Double>> fact =
(recurs) =>
(x) =>
x == 0 ? 1 : x * recurs(x - 1);
Now you have a function that takes a function, and returns another function that sort of looks like a factorial, but instead of calling itself, it calls the argument passed into the outer function. How do you make this the factorial? Pass the inner function to itself. The Y-Combinator does that, by being a function with a permanent name, which can introduce the recursion.
// One-argument Y-Combinator.
public static Func<T, TResult> Y<T, TResult>(Func<Func<T, TResult>, Func<T, TResult>> F)
{
return
t => // A function that...
F( // Calls the factorial creator, passing in...
Y(F) // The result of this same Y-combinator function call...
// (Here is where the recursion is introduced.)
)
(t); // And passes the argument into the work function.
}
Rather than the factorial calling itself, what happens is that the factorial calls the factorial generator (returned by the recursive call to Y-Combinator). And depending on the current value of t the function returned from the generator will either call the generator again, with t - 1, or just return 1, terminating the recursion.
It's complicated and cryptic, but it all shakes out at run-time, and the key to its working is "deferred execution", and the breaking up of the recursion to span two functions. The inner F is passed as an argument, to be called in the next iteration, only if necessary.
You need to convert it to a UNIX timestamp (using strtotime) and then back into the format you require using the date function.
For example:
$currentDateTime = '08/04/2010 22:15:00';
$newDateTime = date('h:i A', strtotime($currentDateTime));
Try this:
df.loc[len(df)]=['8/19/2014','Jun','Fly','98765']
Warning: this method works only if there are no "holes" in the index. For example, suppose you have a dataframe with three rows, with indices 0, 1, and 3 (for example, because you deleted row number 2). Then, len(df) = 3, so by the above command does not add a new row - it overrides row number 3.
like Jesse Jesse Glick and abguy said you can enumerate string into Boolean type:
Boolean.valueOf(string_variable)
or the opposite Boolean into string:
String.valueOf(boolean_variable)
in my case I had to to downstream Boolean parameter to another job. So for this you will need the use the class BooleanParameterValue :
build job: 'downstream_job_name', parameters:
[
[$class: 'BooleanParameterValue', name: 'parameter_name', value: false],
], wait: true
I think the issue is here:
<template id="newtemp" :name ="{{user.name}}">
When you prefix the prop with :
you are indicating to Vue that it is a variable, not a string. So you don't need the {{}}
around user.name
. Try:
<template id="newtemp" :name ="user.name">
EDIT-----
The above is true, but the bigger issue here is that when you change the URL and go to a new route, the original component disappears. In order to have the second component edit the parent data, the second component would need to be a child component of the first one, or just a part of the same component.

This will work if you are not blocking.
If you are planing on doing sleeps, its absolutely imperative that you use the event to do the sleep. If you leverage the event to sleep, if someone tells you to stop while "sleeping" it will wake up. If you use time.sleep()
your thread will only stop after it wakes up.
import threading
import time
duration = 2
def main():
t1_stop = threading.Event()
t1 = threading.Thread(target=thread1, args=(1, t1_stop))
t2_stop = threading.Event()
t2 = threading.Thread(target=thread2, args=(2, t2_stop))
time.sleep(duration)
# stops thread t2
t2_stop.set()
def thread1(arg1, stop_event):
while not stop_event.is_set():
stop_event.wait(timeout=5)
def thread2(arg1, stop_event):
while not stop_event.is_set():
stop_event.wait(timeout=5)
Do this below. Worked for me. I took values from a select box and another textbox. Then on button click I took the entire data in Javascript function and redirected using javascript.
//Search Form
$(document).ready (function($){
$("#searchbtn").click(function showAlert(e){
e.preventDefault();
var cat = $('#category').val();
var srch = $('#srch').val();
if(srch==""){
alert("Search is empty :(");
}
else{
var url = baseurl+'categories/search/'+cat+'/'+srch;
window.location.href=url;
}
});
});
The above code worked for me.
I need to sum the span elements so I edited Akhil Sekharan's answer below.
var arr = document.querySelectorAll('span[id^="score"]');
var total=0;
for(var i=0;i<arr.length;i++){
if(parseInt(arr[i].innerHTML))
total+= parseInt(arr[i].innerHTML);
}
console.log(total)
You can change the elements with other elements link will guide you with editing.
I wanted to display logs on stdout and log file along with the timestamp. None of the above answers worked for me. I made use of process substitution and exec command and came up with the following code. Sample logs:
2017-06-21 11:16:41+05:30 Fetching information about files in the directory...
Add following lines at the top of your script:
LOG_FILE=script.log
exec > >(while read -r line; do printf '%s %s\n' "$(date --rfc-3339=seconds)" "$line" | tee -a $LOG_FILE; done)
exec 2> >(while read -r line; do printf '%s %s\n' "$(date --rfc-3339=seconds)" "$line" | tee -a $LOG_FILE; done >&2)
Hope this helps somebody!
Using redis-cli
, you can stop it trying to save the snapshot:
config set stop-writes-on-bgsave-error no
This is a quick workaround, but if you care about the data you are using it for, you should check to make sure why bgsave failed in first place.
Hopefully this can help others: The above examples use ax.lines
.
With more recent mpl (3.3.1), there is ax.get_lines()
.
This bypasses the need for calling ax.lines=[]
for line in ax.get_lines(): # ax.lines:
line.remove()
# ax.lines=[] # needed to complete removal when using ax.lines
you should not use a.x for accumulator , Instead you can do like this `arr = [{x:1},{x:2},{x:4}]
arr.reduce(function(a,b){a + b.x},0)`
You've almost got it. Tell jquery you want to load only the script:
$("#myBtn").click(function() {
$("#myDiv").load("trackingCode.html script");
});
use this..
$('#video1').attr({'autoplay':'true'});
Be careful using SelectedItem.Text... If there is no item selected, then SelectedItem will be null and SelectedItem.Text will generate a null-value exception.
.NET should have provided a SelectedText property like the SelectedValue property that returns String.Empty when there is no selected item.

Put extra commentary information in the generated assembly code to make it more readable.
[...] The added comments include:
- information on the compiler version and command-line options,
- the source code lines associated with the assembly instructions, in the form FILENAME:LINENUMBER:CONTENT OF LINE,
- hints on which high-level expressions correspond to the various assembly instruction operands.
This is regarding the question asked by Starter.
The problem with your code is that you are not passing the number properly.
The code should be:
private OnClickListener next = new OnClickListener() {
public void onClick(View v) {
EditText num=(EditText)findViewById(R.id.EditText01);
String number = "tel:" + num.getText().toString().trim();
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(number));
startActivity(callIntent);
}
};
Do not forget to add the permission in manifest file.
<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>
or
<uses-permission android:name="android.permission.CALL_PRIVILEGED"></uses-permission>
for emergency number in case DIAL
is used.
For speed, I would do the following, which requires only one pass through each of the two arrays. This method preserves order. I will first present code that does not mutate the original array, then show how it can be easily modified to mutate.
arr = [1,1,1,2,2,3,1]
removals = [1,3,1]
h = removals.group_by(&:itself).transform_values(&:size)
#=> {1=>2, 3=>1}
arr.each_with_object([]) { |n,a|
h.key?(n) && h[n] > 0 ? (h[n] -= 1) : a << n }
#=> [1, 2, 2, 1]
arr
#=> [1, 1, 1, 2, 2, 3, 1]
To mutate arr
write:
h = removals.group_by(&:itself).transform_values(&:count)
arr.replace(arr.each_with_object([]) { |n,a|
h.key?(n) && h[n] > 0 ? (h[n] -= 1) : a << n })
#=> [1, 2, 2, 1]
arr
#=> [1, 2, 2, 1]
This uses the 21st century method Hash#transform_values (new in MRI v2.4), but one could instead write:
h = Hash[removals.group_by(&:itself).map { |k,v| [k,v.size] }]
or
h = removals.each_with_object(Hash.new(0)) { | n,h| h[n] += 1 }
If you need to clear the values of $_SESSION
, set the array equal to an empty array:
$_SESSION = array();
Of course, you can't access the values of $_SESSION
on another page once you call session_destroy
, so it doesn't matter that much.
Try the following:
session_destroy();
$_SESSION = array(); // Clears the $_SESSION variable
Adding in example for solution given earlier. By using socket.io-client
https://github.com/socketio/socket.io-client
Client Side:
//client.js
var io = require('socket.io-client');
var socket = io.connect('http://localhost:3000', {reconnect: true});
// Add a connect listener
socket.on('connect', function (socket) {
console.log('Connected!');
});
socket.emit('CH01', 'me', 'test msg');
Server Side :
//server.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
io.on('connection', function (socket){
console.log('connection');
socket.on('CH01', function (from, msg) {
console.log('MSG', from, ' saying ', msg);
});
});
http.listen(3000, function () {
console.log('listening on *:3000');
});
Run :
Open 2 console and run node server.js
and node client.js
You can't have 1:1 ratio.

All the answers above are correct, but when I use windows and disable the Prettier ESLint extension rvest.vs-code-prettier-eslint
the issue will be fixed.
In my case, the servlet-api.jar file in jre/lib/ext in the jdk directory conflicts with the servlet-api.jar file in tomcat, removing the servlet-api.jar in jre/lib/ext in the jdk directory can solve the problem.
If you would like to not inflate another view just to indicate progress then do the following:
Android will take care the progress bar's visibility.

I find this solution to run a URL every 5 minutes from cPanel you can execute any task by this command.
*/5 * * * *
This on run At every 5th minute. so it only runs once in one hour
Here is an example that i use to run my URL every second
*/5 * * * * curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
sleep 5m; curl http://www.example.com/;
To sleep for 5 seconds, use:
sleep 5
Want to sleep for 5 minutes, use:
sleep 5m
Halt or sleep for 5 hours, use:
sleep 5h
If you do not want any email of cron job just add this to end of the command
>/dev/null 2>&1

Sounds like you should stay with the defaults ;-)
Seriously: The number of maximum parallel connections you should set depends on your expected tomcat usage and also on the number of cores on your server. More cores on your processor => more parallel threads that can be executed.

I know I'm very late to the game, but thought I'd contribute for posterity's sake.
I wrote a short jQuery function that will automatically turn any <address>
tags into Google maps links.
$(document).ready(function () {
//Convert address tags to google map links - Michael Jasper 2012
$('address').each(function () {
var link = "<a href='http://maps.google.com/maps?q=" + encodeURIComponent( $(this).text() ) + "' target='_blank'>" + $(this).text() + "</a>";
$(this).html(link);
});
});
I also came across a situation that called for generating embedded maps from the links, and though I'd share with future travelers:
$(document).ready(function(){
$("address").each(function(){
var embed ="<iframe width='425' height='350' frameborder='0' scrolling='no' marginheight='0' marginwidth='0' src='https://maps.google.com/maps?&q="+ encodeURIComponent( $(this).text() ) +"&output=embed'></iframe>";
$(this).html(embed);
});
});
You can paste it like this:
= "2010-12-20" - 180
And don't forget to format the cell as a Date [CTRL]+[F1] / Number Tab
as?
won't always give you the expected result because as
doesn't test if a data type is of a specific kind but only if a data type can be converted to or represented as specific kind.
Consider this code for example:
func handleError ( error: Error ) {
if let nsError = error as? NSError {
Every data type conforming to the Error
protocol can be converted to a NSError
object, so this will always succeed. Yet that doesn't mean that error
is in fact a NSError
object or a subclass of it.
A correct type check would be:
func handleError ( error: Error ) {
if type(of: error) == NSError.self {
However, this checks for the exact type only. If you want to also include subclass of NSError
, you should use:
func handleError ( error: Error ) {
if error is NSError.Type {
Try this
If @NewStatus = 'InOffice'
BEGIN
Update tblEmployee set InOffice = -1 where EmpID = @EmpID
END
Else If @NewStatus = 'OutOffice'
BEGIN
Update tblEmployee set InOffice = -1 where EmpID = @EmpID
END
Else If @NewStatus = 'Home'
BEGIN
Update tblEmployee set Home = -1 where EmpID = @EmpID
END
I am using bootstrap navigation
This did the job for me including active main dropdown's and the active children
$(document).ready(function () {
var url = window.location;
// Will only work if string in href matches with location
$('ul.nav a[href="' + url + '"]').parent().addClass('active');
// Will also work for relative and absolute hrefs
$('ul.nav a').filter(function () {
return this.href == url;
}).parent().addClass('active').parent().parent().addClass('active');
});
For me, this simply works:
error: function(xhr, status, error) {
alert(xhr.responseText);
}
Javascript in URL will not be executed, on its own. That by no way means its safe or to be trusted.
A URL is another user input not to be trusted, GET or POST (or any other method for that matter) can cause allot of severe vulnerabilities.
A common example was/is the use of the PHP_SELF
, REQUEST_URI
, SCRIPT_NAME
and similar variables. Developers would mistakenly echo them directly to the browser which led to the script being injected into the page and executed.
I would suggest you start to do allot of reading, these are some good places to start:
Also google around for XSS (cross site scripting), XSRF (Cross Site Request Forgery), and SQL Injection. That will get you started, but it is allot of information to absorb so take your time. It will be worth it in the long run.
Import package is for better readability;
Fully qualified class has to be used in special scenarios. For example, same class name in different package, or use reflect such as Class.forName()
.
Instead of SELECT * FROM MyTable WHERE Column1 CONTAINS 'word1 word2 word3'
,
add And in between those words like:
SELECT * FROM MyTable WHERE Column1 CONTAINS 'word1 And word2 And word3'
for details, see here https://msdn.microsoft.com/en-us/library/ms187787.aspx
UPDATE
For selecting phrases, use double quotes like:
SELECT * FROM MyTable WHERE Column1 CONTAINS '"Phrase one" And word2 And "Phrase Two"'
p.s. you have to first enable Full Text Search on the table before using contains keyword. for more details, See here https://docs.microsoft.com/en-us/sql/relational-databases/search/get-started-with-full-text-search
I found how to run the query without error, but I hesitate to call it a "solution" without really understanding the underlying cause.
This more closely resembles the beginning of my actual query:
-- Comment
-- More comment
SELECT rf.flowrow, rf.stage, rf.process,
rf.instr instnum, rf.procedure_id, rtd_history.runtime, rtd_history.waittime
FROM
(
-- Comment at beginning of subquery
-- These two comment lines are the problem
SELECT sub2.flowrow, sub2.stage, sub2.process, sub2.instr, sub2.pid
FROM ( ...
The second set of comments above, at the beginning of the subquery, were the problem. When removed, the query executes. Other comments are fine. This is not a matter of some rogue or missing newline causing the following line to be commented, because the following line is a SELECT. A missing select would yield a different error than "not all variables bound."
I asked around and found one co-worker who has run into this -- comments causing query failures -- several times. Does anyone know how this can be the cause? It is my understanding that the very first thing a DBMS would do with comments is see if they contain hints, and if not, remove them during parsing. How can an ordinary comment containing no unusual characters (just letters and a period) cause an error? Bizarre.
The CSS you have applies color #c1c1c1 to all <a>
elements.
And it also applies color #c1c1c1 to the first <li>
element.
Perhaps the code you posted is missing something because I don't see any other colors being defined.
DateTime xmas = new DateTime(2009, 12, 25);
double daysUntilChristmas = xmas.Subtract(DateTime.Today).TotalDays;
to hide the horizontal scrollbars, you can set overflow-x to hidden, like this:
overflow-x: hidden;
INSERT INTO #TempTable
EXEC(@SelectStatement)
I had problems triggering focus on an element (a form input) that was transitioning into the page. I found it was fixable by invoking the focus event from inside a setTimeout with no delay on it. As I understand it (from, eg. this answer), this delays the function until the current execution queue finishes, so in this case it delays the focus event until the transition has completed.
setTimeout(function(){
$('#goal-input').focus();
});
Ubuntu 11.10 doesn't have maven3 in repo.
Follow below step to install maven3 on ubuntu 11.10
sudo add-apt-repository ppa:natecarlson/maven3
sudo apt-get update && sudo apt-get install maven3
Open terminal: mvn3 -v
if you want mvn as a binary then execute below script:
sudo ln -s /usr/bin/mvn3 /usr/bin/mvn
I hope this will help you.

You have to use v-html directive for displaying html content inside a vue component
<div v-html="html content data property"></div>
As an addition to @ANisus' answer...
below is some information from the "Go in action" book, which I think is worth mentioning:
nil
& empty
slicesIf we think of a slice like this:
[pointer] [length] [capacity]
then:
nil slice: [nil][0][0]
empty slice: [addr][0][0] // points to an address
nil slice
They’re useful when you want to represent a slice that doesn’t exist, such as when an exception occurs in a function that returns a slice.
// Create a nil slice of integers. var slice []int
empty slice
Empty slices are useful when you want to represent an empty collection, such as when a database query returns zero results.
// Use make to create an empty slice of integers. slice := make([]int, 0) // Use a slice literal to create an empty slice of integers. slice := []int{}
Regardless of whether you’re using a nil slice or an empty slice, the built-in functions
append
,len
, andcap
work the same.
package main
import (
"fmt"
)
func main() {
var nil_slice []int
var empty_slice = []int{}
fmt.Println(nil_slice == nil, len(nil_slice), cap(nil_slice))
fmt.Println(empty_slice == nil, len(empty_slice), cap(empty_slice))
}
prints:
true 0 0
false 0 0
You can make use of the removeIf
to remove data from a list conditionally.
Eg:- If you want to remove all even numbers from a list, you can do it as follows.
final List<Integer> list = IntStream.range(1,100).boxed().collect(Collectors.toList());
list.removeIf(number -> number % 2 == 0);
HOW TO COPY AND PASTE ANDROID PROJECT
A. If you are using Eclipse and all you want to do is first open the project that you want to copy(DON"T FORGET TO OPEN THE PROJECT THAT YOU NEED TO COPY), then clone(copy/paste) your Android project within the explorer package window on the left side of Eclipse. Eclipse will ask you for a new project name when you paste. Give it a new project name. Since Eclipse project name and directory are independent of the application name and package, the following steps will help you on how to change package names. Note: there are two types of package names.
1.To change src package names of packages within Src folder follow the following steps: First you need to create new package: (src >>>> right click >>>> new >>>> package).
Example of creating package: com.new.name
Follow these steps to move the Java files from the old copied package in part A to your new package.
Select the Java files within that old package
Right click that java files
select "Refactor" option
select "Move" option
Select your preferred package from the list of packages in a dialogue window. Most probably you need to select the new one you just created and hit "OK"
2.To change Application package name(main package), follow the following steps:
First right click your project
Then go to "Android tools"
Then select "Rename Application package"
Enter a new name in a dialogue window , and hit OK.
Then It will show you in which part of your project the Application name will be changed.
It will show you that the Application name will be changed in manifest, and in most relevant Java files. Hit "OK"
YOU DONE in this part, but make sure you rebuild your project to take effect.
To rebuild your project, go to ""project" >>> "Clean" >>>> select a Project from a projects
list, and hit "OK". Finally, you can run your new project.
We were trying to avoid using the IE specific
$window[0].document.body.clientHeight
And found that the following jQuery will not consistently yield the same value but eventually does at some point in our page load scenario which worked for us and maintained cross-browser support:
$(document).height()
I've solved it another way, if you like.
Here I used two arrays where searchChars containing which will be replaced and replaceChars containing desired characters.
var text = "your input string";_x000D_
var searchChars = ['Å','Ä','å','Ö','ö']; // add more charecter._x000D_
var replaceChars = ['A','A','a','O','o']; // exact same index to searchChars._x000D_
var index;_x000D_
for (var i = 0; i < text.length; i++) {_x000D_
if( $.inArray(text[i], searchChars) >-1 ){ // $.inArray() is from jquery._x000D_
index = searchChars.indexOf(text[i]);_x000D_
text = text.slice(0, i) + replaceChars[index] + text.slice(i+1,text.length);_x000D_
}_x000D_
}
_x000D_
I have done a jQuery plugin that has the same look of jQuery UI Accordion and can keep all tabs\sections open
you can find it here
http://anasnakawa.wordpress.com/2011/01/25/jquery-ui-multi-open-accordion/
works with the same markup
<div id="multiOpenAccordion">
<h3><a href="#">tab 1</a></h3>
<div>Lorem ipsum dolor sit amet</div>
<h3><a href="#">tab 2</a></h3>
<div>Lorem ipsum dolor sit amet</div>
</div>
Javascript code
$(function(){
$('#multiOpenAccordion').multiAccordion();
// you can use a number or an array with active option to specify which tabs to be opened by default:
$('#multiOpenAccordion').multiAccordion({ active: 1 });
// OR
$('#multiOpenAccordion').multiAccordion({ active: [1, 2, 3] });
$('#multiOpenAccordion').multiAccordion({ active: false }); // no opened tabs
});
UPDATE: the plugin has been updated to support default active tabs option
UPDATE: This plugin is now deprecated.
You do not have permision to view this directory or page using the credentials that you supplied.
This happened despite the fact the user is already authenticated via Active Directory.
There can be many causes to Access Denied error, but if you think you’ve already configured everything correctly from your web application, there might be a little detail that’s forgotten. Make sure you give the proper permission to Authenticated Users to access your web application directory.
Here are the steps I took to solve this issue.
Right-click on the directory where the web application is stored and select Properties and click on Security tab.
Click on Click on Edit…, then Add… button. Type in Authenticated Users in the Enter the object names to select., then Add button. Type in Authenticated Users in the Enter the object names to select.
Click OK and you should see Authenticated Users as one of the user names. Give proper permissions on the Permissions for Authenticated Users box on the lower end if they’re not checked already.
Click OK twice to close the dialog box. It should take effect immediately, but if you want to be sure, you can restart IIS for your web application.
Refresh your browser and it should display the web page now.
Hope this helps!

Some people find the following alternative syntax easier to see what is going on:
select t1.value,t2.value
from MyTable t1
inner join MyTable t2 on
t1.id = t2.id
where t1.id = @id
Simply have them in the same controller, and do something like this:
HTML:
<input id="upload"
type="file"
ng-file-select="onFileSelect($files)"
style="display: none;">
<button type="button"
ng-click="startUpload()">Upload</button>
JS:
var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
$scope.files = [];
$scope.startUpload = function(){
for (var i = 0; i < $scope.files.length; i++) {
$upload($scope.files[i]);
}
}
$scope.onFileSelect = function($files) {
$scope.files = $files;
};
}];
This is, in my opinion, the best way to do it in angular. Using jQuery to find the element and trigger an event isn't the best practice.
Under Tools > Preferences > Databases there is a third party JDBC driver path that must be setup. Once the driver path is setup a separate 'MySQL' tab should appear on the New Connections dialog.

For me neither the @Rule
nor the @RunWith(MockitoJUnitRunner.Silent.class)
suggestions worked. It was a legacy project where we upgraded to mockito-core 2.23.0.
We could get rid of the UnnecessaryStubbingException
by using:
Mockito.lenient().when(mockedService.getUserById(any())).thenReturn(new User());
instead of:
when(mockedService.getUserById(any())).thenReturn(new User());
Needless to say that you should rather look at the test code, but we needed to get the stuff compiled and the tests running first of all ;)

You can do that but the changes will affect for new data that is inserted on the database. On the long run follow as suggested above.
Also there are certain tricks you can override the collation, such as parameters for stored procedures or functions, alias data types, and variables are assigned the default collation of the database. To change the collation of an alias type, you must drop the alias and re-create it.
You can override the default collation of a literal string by using the COLLATE clause. If you do not specify a collation, the literal is assigned the database default collation. You can use DATABASEPROPERTYEX to find the current collation of the database.
You can override the server, database, or column collation by specifying a collation in the ORDER BY clause of a SELECT statement.
One more way. Select the target table in the left panel in phpMyAdmin, click on Export tab, unselect Data block and click on Go button.
From my point of view, disable images caching is a bad idea. At all.
The root problem here is - how to force browser to update image, when it has been updated on a server side.
Again, from my personal point of view, the best solution is to disable direct access to images. Instead access images via server-side filter/servlet/other similar tools/services.
In my case it's a rest service, that returns image and attaches ETag in response. The service keeps hash of all files, if file is changed, hash is updated. It works perfectly in all modern browsers. Yes, it takes time to implement it, but it is worth it.
The only exception - are favicons. For some reasons, it does not work. I could not force browser to update its cache from server side. ETags, Cache Control, Expires, Pragma headers, nothing helped.
In this case, adding some random/version parameter into url, it seems, is the only solution.
You can try using fast-export:
cd ~
git clone https://github.com/frej/fast-export.git
git init git_repo
cd git_repo
~/fast-export/hg-fast-export.sh -r /path/to/old/mercurial_repo
git checkout HEAD
Also have a look at this SO question.
If you're using Mercurial version below 4.6, adrihanu got your back:
As he stated in his comment: "In case you use Mercurial < 4.6 and you got "revsymbol not found" error. You need to update your Mercurial or downgrade fast-export by running git checkout tags/v180317 inside ~/fast-export directory.".
crypto-js is a rich javascript library containing many cryptography algorithms.
All you have to do is just call CryptoJS.MD5(password)
$.post(
'includes/login.php',
{ user: username, pass: CryptoJS.MD5(password) },
onLogin,
'json' );
create table encrypt(username varchar(20),password varbinary(200))
insert into encrypt values('raju',aes_encrypt('kumar','key')) select *,cast(aes_decrypt(password,'key') as char(40)) from encrypt where username='raju';
In addition mysql passwords when not using the IDENTIFIED BY
clause, may be blank values, if non-blank, they may be encrypted. But yes USAGE
is used to modify an account by granting simple resource limiters such as MAX_QUERIES_PER_HOUR
, again this can be specified by also
using the WITH clause, in conjuction with GRANT USAGE
(no privileges added) or GRANT ALL
, you can also specify GRANT USAGE
at the global level, database level, table level,etc....

Based on muhuk answer I did this simple tag encapsulating python string.format
method.
templatetags
at your's application folder. format.py
file on it.Add this to it:
from django import template
register = template.Library()
@register.filter(name='format')
def format(value, fmt):
return fmt.format(value)
{% load format %}
{{ some_value|format:"{:0.2f}" }}
If you want multiple files, you can use this
var input = document.querySelector('input[type="file"]')
var data = new FormData()
for (const file of input.files) {
data.append('files',file,file.name)
}
fetch('/avatars', {
method: 'POST',
body: data
})
For Googlers, another way to get a list of users is to use:
Get-WmiObject -Class Win32_UserAccount
A reference can not be NULL. The interface makes you pass a real object into the function.
So there is no need to test for NULL. This is one of the reasons that references were introduced into C++.
Note you can still write a function that takes a pointer. In this situation you still need to test for NULL. If the value is NULL then you return early just like in C. Note: You should not be using exceptions when a pointer is NULL. If a parameter should never be NULL then you create an interface that uses a reference.
String s1 = "";
means that the empty String
is assigned to s1
.
In this case, s1.length()
is the same as "".length()
, which will yield 0
as expected.
String s2 = null;
means that (null
) or "no value at all" is assigned to s2
. So this one, s2.length()
is the same as null.length()
, which will yield a NullPointerException
as you can't call methods on null
variables (pointers, sort of) in Java.
Also, a point, the statement
String s1;
Actually has the same effect as:
String s1 = null;
Whereas
String s1 = "";
Is, as said, a different thing.
Contrary to what cularis said there can be both in the parameter map.
The best way I see is to proxy the parameterMap and for each parameter retrieval check if queryString contains "&?<parameterName>=".
Note that parameterName needs to be URL encoded before this check can be made, as Qerub pointed out.
That saves you the parsing and still gives you only URL parameters.

I fixed the issue today using the steps below:
If config.inc.php does not exists in phpMyadmin directory Copy config.sample.inc.php to config.inc.php.
Add socket to /* Server parameters */
$cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';
Save the file and access phpmyadmin through url.
If you are using the mysql 8.0.12 you should use legacy password encryption as the strong encryption is not supported by the php client.

Copying and pasting by user interactions emulation could be not reliable (for example, popup appears and it switches the focus). You may be interested in trying the commercial ByteScout PDF Extractor SDK that is specifically designed to extract data from PDF and it works from VBA. It is also capable of extracting data from invoices and tables as CSV using VB code.
Here is the VBA code for Excel to extract text from given locations and save them into cells in the Sheet1
:
Private Sub CommandButton1_Click()
' Create TextExtractor object
' Set extractor = CreateObject("Bytescout.PDFExtractor.TextExtractor")
Dim extractor As New Bytescout_PDFExtractor.TextExtractor
extractor.RegistrationName = "demo"
extractor.RegistrationKey = "demo"
' Load sample PDF document
extractor.LoadDocumentFromFile ("c:\sample1.pdf")
' Get page count
pageCount = extractor.GetPageCount()
Dim wb As Workbook
Dim ws As Worksheet
Dim TxtRng As Range
Set wb = ActiveWorkbook
Set ws = wb.Sheets("Sheet1")
For i = 0 To pageCount - 1
RectLeft = 10
RectTop = 10
RectWidth = 100
RectHeight = 100
' check the same text is extracted from returned coordinates
extractor.SetExtractionArea RectLeft, RectTop, RectWidth, RectHeight
' extract text from given area
extractedText = extractor.GetTextFromPage(i)
' insert rows
' Rows(1).Insert shift:=xlShiftDown
' write cell value
Set TxtRng = ws.Range("A" & CStr(i + 2))
TxtRng.Value = extractedText
Next
Set extractor = Nothing

Basically, eval
is used to evaluate a single dynamically generated Python expression, and exec
is used to execute dynamically generated Python code only for its side effects.
eval
and exec
have these two differences:
eval
accepts only a single expression, exec
can take a code block that has Python statements: loops, try: except:
, class
and function/method def
initions and so on.
An expression in Python is whatever you can have as the value in a variable assignment:
a_variable = (anything you can put within these parentheses is an expression)
eval
returns the value of the given expression, whereas exec
ignores the return value from its code, and always returns None
(in Python 2 it is a statement and cannot be used as an expression, so it really does not return anything).
In versions 1.0 - 2.7, exec
was a statement, because CPython needed to produce a different kind of code object for functions that used exec
for its side effects inside the function.
In Python 3, exec
is a function; its use has no effect on the compiled bytecode of the function where it is used.
Thus basically:
>>> a = 5
>>> eval('37 + a') # it is an expression
42
>>> exec('37 + a') # it is an expression statement; value is ignored (None is returned)
>>> exec('a = 47') # modify a global variable as a side effect
>>> a
47
>>> eval('a = 47') # you cannot evaluate a statement
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1
a = 47
^
SyntaxError: invalid syntax
The compile
in 'exec'
mode compiles any number of statements into a bytecode that implicitly always returns None
, whereas in 'eval'
mode it compiles a single expression into bytecode that returns the value of that expression.
>>> eval(compile('42', '<string>', 'exec')) # code returns None
>>> eval(compile('42', '<string>', 'eval')) # code returns 42
42
>>> exec(compile('42', '<string>', 'eval')) # code returns 42,
>>> # but ignored by exec
In the 'eval'
mode (and thus with the eval
function if a string is passed in), the compile
raises an exception if the source code contains statements or anything else beyond a single expression:
>>> compile('for i in range(3): print(i)', '<string>', 'eval')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1
for i in range(3): print(i)
^
SyntaxError: invalid syntax
Actually the statement "eval accepts only a single expression" applies only when a string (which contains Python source code) is passed to eval
. Then it is internally compiled to bytecode using compile(source, '<string>', 'eval')
This is where the difference really comes from.
If a code
object (which contains Python bytecode) is passed to exec
or eval
, they behave identically, excepting for the fact that exec
ignores the return value, still returning None
always. So it is possible use eval
to execute something that has statements, if you just compile
d it into bytecode before instead of passing it as a string:
>>> eval(compile('if 1: print("Hello")', '<string>', 'exec'))
Hello
>>>
works without problems, even though the compiled code contains statements. It still returns None
, because that is the return value of the code object returned from compile
.
In the 'eval'
mode (and thus with the eval
function if a string is passed in), the compile
raises an exception if the source code contains statements or anything else beyond a single expression:
>>> compile('for i in range(3): print(i)', '<string>'. 'eval')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1
for i in range(3): print(i)
^
SyntaxError: invalid syntax
exec
and eval
The exec
function (which was a statement in Python 2) is used for executing a dynamically created statement or program:
>>> program = '''
for i in range(3):
print("Python is cool")
'''
>>> exec(program)
Python is cool
Python is cool
Python is cool
>>>
The eval
function does the same for a single expression, and returns the value of the expression:
>>> a = 2
>>> my_calculation = '42 * a'
>>> result = eval(my_calculation)
>>> result
84
exec
and eval
both accept the program/expression to be run either as a str
, unicode
or bytes
object containing source code, or as a code
object which contains Python bytecode.
If a str
/unicode
/bytes
containing source code was passed to exec
, it behaves equivalently to:
exec(compile(source, '<string>', 'exec'))
and eval
similarly behaves equivalent to:
eval(compile(source, '<string>', 'eval'))
Since all expressions can be used as statements in Python (these are called the Expr
nodes in the Python abstract grammar; the opposite is not true), you can always use exec
if you do not need the return value. That is to say, you can use either eval('my_func(42)')
or exec('my_func(42)')
, the difference being that eval
returns the value returned by my_func
, and exec
discards it:
>>> def my_func(arg):
... print("Called with %d" % arg)
... return arg * 2
...
>>> exec('my_func(42)')
Called with 42
>>> eval('my_func(42)')
Called with 42
84
>>>
Of the 2, only exec
accepts source code that contains statements, like def
, for
, while
, import
, or class
, the assignment statement (a.k.a a = 42
), or entire programs:
>>> exec('for i in range(3): print(i)')
0
1
2
>>> eval('for i in range(3): print(i)')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1
for i in range(3): print(i)
^
SyntaxError: invalid syntax
Both exec
and eval
accept 2 additional positional arguments - globals
and locals
- which are the global and local variable scopes that the code sees. These default to the globals()
and locals()
within the scope that called exec
or eval
, but any dictionary can be used for globals
and any mapping
for locals
(including dict
of course). These can be used not only to restrict/modify the variables that the code sees, but are often also used for capturing the variables that the exec
uted code creates:
>>> g = dict()
>>> l = dict()
>>> exec('global a; a, b = 123, 42', g, l)
>>> g['a']
123
>>> l
{'b': 42}
(If you display the value of the entire g
, it would be much longer, because exec
and eval
add the built-ins module as __builtins__
to the globals automatically if it is missing).
In Python 2, the official syntax for the exec
statement is actually exec code in globals, locals
, as in
>>> exec 'global a; a, b = 123, 42' in g, l
However the alternate syntax exec(code, globals, locals)
has always been accepted too (see below).
compile
The compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1)
built-in can be used to speed up repeated invocations of the same code with exec
or eval
by compiling the source into a code
object beforehand. The mode
parameter controls the kind of code fragment the compile
function accepts and the kind of bytecode it produces. The choices are 'eval'
, 'exec'
and 'single'
:
'eval'
mode expects a single expression, and will produce bytecode that when run will return the value of that expression:
>>> dis.dis(compile('a + b', '<string>', 'eval'))
1 0 LOAD_NAME 0 (a)
3 LOAD_NAME 1 (b)
6 BINARY_ADD
7 RETURN_VALUE
'exec'
accepts any kinds of python constructs from single expressions to whole modules of code, and executes them as if they were module top-level statements. The code object returns None
:
>>> dis.dis(compile('a + b', '<string>', 'exec'))
1 0 LOAD_NAME 0 (a)
3 LOAD_NAME 1 (b)
6 BINARY_ADD
7 POP_TOP <- discard result
8 LOAD_CONST 0 (None) <- load None on stack
11 RETURN_VALUE <- return top of stack
'single'
is a limited form of 'exec'
which accepts a source code containing a single statement (or multiple statements separated by ;
) if the last statement is an expression statement, the resulting bytecode also prints the repr
of the value of that expression to the standard output(!).
An if
-elif
-else
chain, a loop with else
, and try
with its except
, else
and finally
blocks is considered a single statement.
A source fragment containing 2 top-level statements is an error for the 'single'
, except in Python 2 there is a bug that sometimes allows multiple toplevel statements in the code; only the first is compiled; the rest are ignored:
In Python 2.7.8:
>>> exec(compile('a = 5\na = 6', '<string>', 'single'))
>>> a
5
And in Python 3.4.2:
>>> exec(compile('a = 5\na = 6', '<string>', 'single'))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1
a = 5
^
SyntaxError: multiple statements found while compiling a single statement
This is very useful for making interactive Python shells. However, the value of the expression is not returned, even if you eval
the resulting code.
Thus greatest distinction of exec
and eval
actually comes from the compile
function and its modes.
In addition to compiling source code to bytecode, compile
supports compiling abstract syntax trees (parse trees of Python code) into code
objects; and source code into abstract syntax trees (the ast.parse
is written in Python and just calls compile(source, filename, mode, PyCF_ONLY_AST)
); these are used for example for modifying source code on the fly, and also for dynamic code creation, as it is often easier to handle the code as a tree of nodes instead of lines of text in complex cases.
While eval
only allows you to evaluate a string that contains a single expression, you can eval
a whole statement, or even a whole module that has been compile
d into bytecode; that is, with Python 2, print
is a statement, and cannot be eval
led directly:
>>> eval('for i in range(3): print("Python is cool")')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1
for i in range(3): print("Python is cool")
^
SyntaxError: invalid syntax
compile
it with 'exec'
mode into a code
object and you can eval
it; the eval
function will return None
.
>>> code = compile('for i in range(3): print("Python is cool")',
'foo.py', 'exec')
>>> eval(code)
Python is cool
Python is cool
Python is cool
If one looks into eval
and exec
source code in CPython 3, this is very evident; they both call PyEval_EvalCode
with same arguments, the only difference being that exec
explicitly returns None
.
exec
between Python 2 and Python 3One of the major differences in Python 2 is that exec
is a statement and eval
is a built-in function (both are built-in functions in Python 3).
It is a well-known fact that the official syntax of exec
in Python 2 is exec code [in globals[, locals]]
.
Unlike majority of the Python 2-to-3 porting guides seem to suggest, the exec
statement in CPython 2 can be also used with syntax that looks exactly like the exec
function invocation in Python 3. The reason is that Python 0.9.9 had the exec(code, globals, locals)
built-in function! And that built-in function was replaced with exec
statement somewhere before Python 1.0 release.
Since it was desirable to not break backwards compatibility with Python 0.9.9, Guido van Rossum added a compatibility hack in 1993: if the code
was a tuple of length 2 or 3, and globals
and locals
were not passed into the exec
statement otherwise, the code
would be interpreted as if the 2nd and 3rd element of the tuple were the globals
and locals
respectively. The compatibility hack was not mentioned even in Python 1.4 documentation (the earliest available version online); and thus was not known to many writers of the porting guides and tools, until it was documented again in November 2012:
The first expression may also be a tuple of length 2 or 3. In this case, the optional parts must be omitted. The form
exec(expr, globals)
is equivalent toexec expr in globals
, while the formexec(expr, globals, locals)
is equivalent toexec expr in globals, locals
. The tuple form ofexec
provides compatibility with Python 3, whereexec
is a function rather than a statement.
Yes, in CPython 2.7 that it is handily referred to as being a forward-compatibility option (why confuse people over that there is a backward compatibility option at all), when it actually had been there for backward-compatibility for two decades.
Thus while exec
is a statement in Python 1 and Python 2, and a built-in function in Python 3 and Python 0.9.9,
>>> exec("print(a)", globals(), {'a': 42})
42
has had identical behaviour in possibly every widely released Python version ever; and works in Jython 2.5.2, PyPy 2.3.1 (Python 2.7.6) and IronPython 2.6.1 too (kudos to them following the undocumented behaviour of CPython closely).
What you cannot do in Pythons 1.0 - 2.7 with its compatibility hack, is to store the return value of exec
into a variable:
Python 2.7.11+ (default, Apr 17 2016, 14:00:29)
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a = exec('print(42)')
File "<stdin>", line 1
a = exec('print(42)')
^
SyntaxError: invalid syntax
(which wouldn't be useful in Python 3 either, as exec
always returns None
), or pass a reference to exec
:
>>> call_later(exec, 'print(42)', delay=1000)
File "<stdin>", line 1
call_later(exec, 'print(42)', delay=1000)
^
SyntaxError: invalid syntax
Which a pattern that someone might actually have used, though unlikely;
Or use it in a list comprehension:
>>> [exec(i) for i in ['print(42)', 'print(foo)']
File "<stdin>", line 1
[exec(i) for i in ['print(42)', 'print(foo)']
^
SyntaxError: invalid syntax
which is abuse of list comprehensions (use a for
loop instead!).
As a follow-up to the accepted answer, this is a minimal definition of the IHTMLScriptElement
interface which does not require to include additional type libraries:
[ComImport, ComVisible(true), Guid(@"3050f28b-98b5-11cf-bb82-00aa00bdce0b")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIDispatch)]
[TypeLibType(TypeLibTypeFlags.FDispatchable)]
public interface IHTMLScriptElement
{
[DispId(1006)]
string text { set; [return: MarshalAs(UnmanagedType.BStr)] get; }
}
So a full code inside a WebBrowser control derived class would look like:
protected override void OnDocumentCompleted(
WebBrowserDocumentCompletedEventArgs e)
{
base.OnDocumentCompleted(e);
// Disable text selection.
var doc = Document;
if (doc != null)
{
var heads = doc.GetElementsByTagName(@"head");
if (heads.Count > 0)
{
var scriptEl = doc.CreateElement(@"script");
if (scriptEl != null)
{
var element = (IHTMLScriptElement)scriptEl.DomElement;
element.text =
@"function disableSelection()
{
document.body.onselectstart=function(){ return false; };
document.body.ondragstart=function() { return false; };
}";
heads[0].AppendChild(scriptEl);
doc.InvokeScript(@"disableSelection");
}
}
}
}

I think Semaphore is what you are looking for, it will block the main process after counting down to 0. Sample code:
from multiprocessing import Process
from multiprocessing import Semaphore
import time
def f(name, sema):
print('process {} starting doing business'.format(name))
# simulate a time-consuming task by sleeping
time.sleep(5)
# `release` will add 1 to `sema`, allowing other
# processes blocked on it to continue
sema.release()
if __name__ == '__main__':
concurrency = 20
total_task_num = 1000
sema = Semaphore(concurrency)
all_processes = []
for i in range(total_task_num):
# once 20 processes are running, the following `acquire` call
# will block the main process since `sema` has been reduced
# to 0. This loop will continue only after one or more
# previously created processes complete.
sema.acquire()
p = Process(target=f, args=(i, sema))
all_processes.append(p)
p.start()
# inside main process, wait for all processes to finish
for p in all_processes:
p.join()
The following code is more structured since it acquires and releases sema
in the same function. However, it will consume too much resources if total_task_num
is very large:
from multiprocessing import Process
from multiprocessing import Semaphore
import time
def f(name, sema):
print('process {} starting doing business'.format(name))
# `sema` is acquired and released in the same
# block of code here, making code more readable,
# but may lead to problem.
sema.acquire()
time.sleep(5)
sema.release()
if __name__ == '__main__':
concurrency = 20
total_task_num = 1000
sema = Semaphore(concurrency)
all_processes = []
for i in range(total_task_num):
p = Process(target=f, args=(i, sema))
all_processes.append(p)
# the following line won't block after 20 processes
# have been created and running, instead it will carry
# on until all 1000 processes are created.
p.start()
# inside main process, wait for all processes to finish
for p in all_processes:
p.join()
The above code will create total_task_num
processes but only concurrency
processes will be running while other processes are blocked, consuming precious system resources.
i found an easy solution, export the database, edit it what you want to edit in a text editor, then import it. Done
It is very easy.
First create a connection , lets name it, con
.
Then run the following code.
get_column_names=con.execute("select * from table_name limit 1")
col_name=[i[0] for i in get_column_names.description]
print(col_name)
You will get column name as a list
An optional prefix
!
which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

I had this same problem and discovered (via this answer to a similar question) that the problem was that I didn't properly indent the docstring properly. Unfortunately IDLE doesn't give useful feedback here, but once I fixed the docstring indentation, the problem went away.
Specifically --- bad code that generates indentation errors:
def my_function(args):
"Here is my docstring"
....
Good code that avoids indentation errors:
def my_function(args):
"Here is my docstring"
....
Note: I'm not saying this is the problem, but that it might be, because in my case, it was!
Here's a better option:
git remote set-head -a origin
From the documentation:
With -a, the remote is queried to determine its HEAD, then $GIT_DIR/remotes//HEAD is set to the same branch. e.g., if the remote HEAD is pointed at next, "git remote set-head origin -a" will set $GIT_DIR/refs/remotes/origin/HEAD to refs/remotes/origin/next. This will only work if refs/remotes/origin/next already exists; if not it must be fetched first.
This has actually been around quite a while (since v1.6.3); not sure how I missed it!
try this code I think it is more optimal.
HeaderRow is used to repeat the header of the table for each new page automatically
BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false);
iTextSharp.text.Font times = new iTextSharp.text.Font(bfTimes, 6, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);
PdfPTable table = new PdfPTable(10) { HorizontalAlignment = Element.ALIGN_CENTER, WidthPercentage = 100, HeaderRows = 2 };
table.SetWidths(new float[] { 2f, 6f, 6f, 3f, 5f, 8f, 5f, 5f, 5f, 5f });
table.AddCell(new PdfPCell(new Phrase("SER.\nNO.", times)) { Rowspan = 2, GrayFill = 0.95f });
table.AddCell(new PdfPCell(new Phrase("TYPE OF SHIPPING", times)) { GrayFill = 0.95f });
table.AddCell(new PdfPCell(new Phrase("ORDER NO.", times)) { GrayFill = 0.95f });

Why not use .style
of the DOM element? It's an object which contains members such as width
and backgroundColor
.
Now no need to Boxing (i.e no need to Creating OBJECT
using new Operator use valueOf insted with compareTo of Collections.Sort..)
1)For Ascending order
Collections.sort(temp, new Comparator<XYZBean>()
{
@Override
public int compare(XYZBean lhs, XYZBean rhs) {
return Integer.valueOf(lhs.getDistance()).compareTo(rhs.getDistance());
}
});
1)For Deascending order
Collections.sort(temp, new Comparator<XYZBean>()
{
@Override
public int compare(XYZBean lhs, XYZBean rhs) {
return Integer.valueOf(rhs.getDistance()).compareTo(lhs.getDistance());
}
});
That can be done using the limit function, this might not seem new but i have added something.The code should go:
SELECT * FROM table_name LIMIT 100,10;
for the above case assume that you have 110 rows from the table and you want to select the last ten, 100 is the row you want to start to print(if you are to print), and ten shows how many rows you want to pick from the table. For a more precised way you can start by selecting all the rows you want to print out and then you grab the last row id if you have an id column(i recommend you put one) then subtract ten from the last id number and that will be where you want to start, this will make your program to function autonomously and for any number of rows, but if you write the value directly i think you will have to change the code every time data is inserted into your table.I think this helps.Pax et Bonum.
MediaQuery.of(context).size.width
apply this code for get the ipaddress:
if (getenv('HTTP_X_FORWARDED_FOR')) { $pipaddress = getenv('HTTP_X_FORWARDED_FOR');
$ipaddress = getenv('REMOTE_ADDR');
echo "Your Proxy IP address is : ".$pipaddress. "(via $ipaddress)" ; }
else { $ipaddress = getenv('REMOTE_ADDR'); echo "Your IP address is : $ipaddress"; }

Executing the script below worked for me.

A list of HTTP Status Codes
The good-practice regarding status response is to, predictably, send the proper HTTP status code depending on the error (4xx for client errors, 5xx for server errors), regarding the actual JSON response there's no "bible" but a good idea could be to send (again) the status and data as 2 different properties of the root object in a successful response (this way you are giving the client the chance to capture the status from the HTTP headers and the payload itself) and a 3rd property explaining the error in a human-understandable way in the case of an error.
Stripe's API behaves similarly in the real world.
i.e.
OK
200, {status: 200, data: [...]}
Error
400, {status: 400, data: null, message: "You must send foo and bar to baz..."}
This worked for me:-

It is not necessary to encode a colon as %3B in the query, although doing so is not illegal.
URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
query = *( pchar / "/" / "?" )
pchar = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded = "%" HEXDIG HEXDIG
sub-delims = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "="
It also seems that only percent-encoded spaces are valid, as I doubt that space is an ALPHA or a DIGIT
look to the URI specification for more details.
I went through this when trying to get a clientcert and private key out of a keystore.
The link above posted by welsh was great, but there was an extra step on my redhat distribution. If curl is built with NSS ( run curl --version
to see if you see NSS listed) then you need to import the keys into an NSS keystore. I went through a bunch of convoluted steps, so this may not be the cleanest way, but it got things working
So export the keys into .p12
keytool -importkeystore -srckeystore $jksfile -destkeystore $p12file \ -srcstoretype JKS -deststoretype PKCS12 \ -srcstorepass $jkspassword -deststorepass $p12password -srcalias $myalias -destalias $myalias \ -srckeypass $keypass -destkeypass $keypass -noprompt
And generate the pem file that holds only the key
echo making ${fileroot}.key.pem openssl pkcs12 -in $p12 -out ${fileroot}.key.pem \ -passin pass:$p12password \ -passout pass:$p12password -nocerts
mkdir ~/nss chmod 700 ~/nss certutil -N -d ~/nss
pks12util -i <mykeys>.p12 -d ~/nss -W <password for cert >
Now curl should work.
curl --insecure --cert <client cert alias>:<password for cert> \ --key ${fileroot}.key.pem <URL>
As I mentioned, there may be other ways to do this, but at least this was repeatable for me. If curl is compiled with NSS support, I was not able to get it to pull the client cert from a file.
You want a check constraint.
CHECK constraints determine the valid values from a logical expression that is not based on data in another column. For example, the range of values for a salary column can be limited by creating a CHECK constraint that allows for only data that ranges from $15,000 through $100,000. This prevents salaries from being entered beyond the regular salary range.
You want something like:
ALTER TABLE dbo.Table ADD CONSTRAINT CK_Table_Frequency
CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))
You can also implement check constraints with scalar functions, as described in the link above, which is how I prefer to do it.
Try adding this to the .htaccess
file in that directory.
Options -Indexes
This has more information.
You can specify also imagePullPolicy: Never
in the container's spec:
containers:
- name: nginx
imagePullPolicy: Never
image: custom-nginx
ports:

Quick and dirty way (e.g. to see how data is stored in oracle)
SQL> select dump(dummy) dump_dummy, dummy
, dump(10) dump_ten
from dual
DUMP_DUMMY DUMMY DUMP_TEN
---------------- ----- --------------------
Typ=1 Len=1: 88 X Typ=2 Len=2: 193,11
1 row selected.
will show that dummy column in table sys.dual has typ=1 (varchar2), while 10 is Typ=2 (number).
What is the "Visual C#"? There is no such thing. Just C#, or .NET C# :)
Also, Python's convention for constants CONSTANT_NAME
is not very common in C#. We are usually using CamelCase according to MSDN standards, e.g. public const string ExtractedMagicString = "vs2019";
Source: Defining constants in C#
Try trimming the string to make sure there is no extra white space:
Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);
Also use c.moveToFirst()
like @thinksteep mentioned.
This is a complete code for select statements.
SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
do {
// Passing values
String column1 = c.getString(0);
String column2 = c.getString(1);
String column3 = c.getString(2);
// Do something Here with values
} while(c.moveToNext());
}
c.close();
db.close();
If you are using Apache reverse proxy for serving an app running on a localhost port you must add a location to your vhost.
<Location />
ProxyPass http://localhost:1339/ retry=0
ProxyPassReverse http://localhost:1339/
ProxyPreserveHost On
ProxyErrorOverride Off
</Location>
To get the IP address have following options
console.log(">>>", req.ip);// this works fine for me returned a valid ip address
console.log(">>>", req.headers['x-forwarded-for'] );// returned a valid IP address
console.log(">>>", req.headers['X-Real-IP'] ); // did not work returned undefined
console.log(">>>", req.connection.remoteAddress );// returned the loopback IP address
So either use req.ip or req.headers['x-forwarded-for']
The name

ES6 / Arrow functions version based on Francis' code (i.e. the top answer):
const randomIntFromInterval = (min, max) => Math.floor(Math.random() * (max - min + 1) + min);
Took the general approach of @Hunan-Rostomyan, made it a litle more concise and added excludeDirs
argument. It'd be trivial to extend with includeDirs
, just follow same pattern:
import * as fs from 'fs';
import * as path from 'path';
function fileList(dir, excludeDirs?) {
return fs.readdirSync(dir).reduce(function (list, file) {
const name = path.join(dir, file);
if (fs.statSync(name).isDirectory()) {
if (excludeDirs && excludeDirs.length) {
excludeDirs = excludeDirs.map(d => path.normalize(d));
const idx = name.indexOf(path.sep);
const directory = name.slice(0, idx === -1 ? name.length : idx);
if (excludeDirs.indexOf(directory) !== -1)
return list;
}
return list.concat(fileList(name, excludeDirs));
}
return list.concat([name]);
}, []);
}
Example usage:
console.log(fileList('.', ['node_modules', 'typings', 'bower_components']));
Another workaround would be to make use of prettier to format the JSON. The example below is using 'json' parser but it could also use 'json5', see list of valid parsers.
const prettier = require("prettier");
console.log(prettier.format(JSON.stringify(object),{ semi: false, parser: "json" }));
In the POSIX standard, which /bin/sh
is supposed to respect, the command is .
(a single dot), not source
. The source
command is a csh
-ism that has been pulled into bash
.
Try
. $env_name/bin/activate
Or if you must have non-POSIX bash
-isms in your code, use #!/bin/bash
.

The Java Service Wrapper might help you, depending on your requirements.
git ignore is a convention in git. Setting a file by the name of .gitignore
will ignore the files in that directory and deeper directories that match the
patterns that the file contains. The most common use is just to have one file
like this at the top level. But you can add others deeper in your directory
structure to ignore even more patterns or stop ignoring them for that directory
and subsequently deeper ones.
Likewise, you can "unignore" certain files in a deeper structure or a specific
subset (ie, you ignore *.log but want to still track important.log) by
specifying patterns beginning with !
. eg:
*.log !important.log
will ignore all log files but will track files named important.log
If you are tracking files you meant to ignore, delete them, add the pattern to you .gitignore file and add all the changes
# delete files that should be ignored, or untrack them with
# git rm --cached <file list or pattern>
# stage all the changes git commit
git add -A
from now on your repository will not have them tracked.
If you would like to clean up your history, you can
# if you want to correct the last 10 commits
git rebase -i --preserve-merges HEAD~10
then mark each commit with e
or edit
. Save the plan. Now git will replay
your history stopping at each commit you marked with e. Here you delete the
files you don't want, git add -A
and then git rebase --continue
until you
are done. Your history will be clean. Make sure you tell you coworkers as you
will have to force push and they will have to rebase what they didn't push yet.

Try the following.
Execute a database backup query from PHP file. Below is an example of using SELECT INTO OUTFILE query for creating table backup:
<?php
$DB_HOST = "localhost";
$DB_USER = "xxx";
$DB_PASS = "xxx";
$DB_NAME = "xxx";
$con = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);
if($con->connect_errno > 0) {
die('Connection failed [' . $con->connect_error . ']');
}
$tableName = 'yourtable';
$backupFile = 'backup/yourtable.sql';
$query = "SELECT * INTO OUTFILE '$backupFile' FROM $tableName";
$result = mysqli_query($con,$query);
?>
To restore the backup you just need to run LOAD DATA INFILE query like this:
<?php
$DB_HOST = "localhost";
$DB_USER = "xxx";
$DB_PASS = "xxx";
$DB_NAME = "xxx";
$con = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);
if($con->connect_errno > 0) {
die('Connection failed [' . $con->connect_error . ']');
}
$tableName = 'yourtable';
$backupFile = 'yourtable.sql';
$query = "LOAD DATA INFILE 'backupFile' INTO TABLE $tableName";
$result = mysqli_query($con,$query);
?>
Running a from class inside your JAR file load.jar
is possible via
java -jar load.jar
When doing so, you have to define the application entry point. Usually this is done by providing a manifest file that contains the Main-Class
tag. For documentation and examples have a look at this page.
The argument load=2
can be supplied like in a normal Java applications:
java -jar load.jar load=2
Having also the current directory contained in the classpath, required to also make use of the Class-Path
tag. See here for more information.
Type a value in one cell (EX:B4 CELL). For temporary use this formula in other cell (once done delete it). =CONCAT(XY,B4) . click and drag till the value you need. Copy the whole column and right click paste only values (second option).
I tried and it's working as expected.
import pandas as pd
df = pd.read_fwf('log.txt')
df.to_csv('log.csv')
Two ways:
Have a bean implement ApplicationListener<ContextClosedEvent>
. onApplicationEvent()
will get called before the context and all the beans are destroyed.
Have a bean implement Lifecycle or SmartLifecycle. stop()
will get called before the context and all the beans are destroyed.
Either way you can shut down the task stuff before the bean destroying mechanism takes place.
Eg:
@Component
public class ContextClosedHandler implements ApplicationListener<ContextClosedEvent> {
@Autowired ThreadPoolTaskExecutor executor;
@Autowired ThreadPoolTaskScheduler scheduler;
@Override
public void onApplicationEvent(ContextClosedEvent event) {
scheduler.shutdown();
executor.shutdown();
}
}
(Edit: Fixed method signature)
Watch out if you are going to compare dates after the conversion!
For instance, I got simulator's asset with date as TimeInterval(366144731.9), converted to milliseconds Int64(1344451931900) and back to TimeInterval(366144731.9000001), using
func convertToMilli(timeIntervalSince1970: TimeInterval) -> Int64 {
return Int64(timeIntervalSince1970 * 1000)
}
func convertMilliToDate(milliseconds: Int64) -> Date {
return Date(timeIntervalSince1970: (TimeInterval(milliseconds) / 1000))
}
I tried to fetch the asset by creationDate and it doesn't find the asset, as you could figure, the numbers are not the same.
I tried multiple solutions to reduce double's decimal precision, like round(interval*1000)/1000, use NSDecimalNumber, etc... with no success.
I ended up fetching by interval -1 < creationDate < interval + 1, instead of creationDate == Interval.
There may be a better solution!?
In Python 3, one can just use print():
print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)
almost out of the box:
import sys
print("Hello, world!", file=sys.stderr)
or:
from sys import stderr
print("Hello, world!", file=stderr)
This is straightforward and does not need to include anything besides sys.stderr
.
Another sort of workaround might be...
Use the HTML:
<input type="text" id="myselect"/>
<datalist id="myselect">
<option>option 1</option>
<option>option 2</option>
<option>option 3</option>
<option>option 4</option>
</datalist>
In Firefox at least a focus followed by a click drops down the list of known valid values as the <datalist>
elements IFF the field happens to be empty. Otherwise, one must clear the field to see valid choices as one types in data. A new value is accepted as typed. One must handle new values in JS or other to persist them.
This is not perfect, but it suffices for my minimalist needs, so I thought I would share.

item = objects.Find(obj => obj.property==myValue);
Just to elaborate on Heyvoon's (2015.06.08) response using Powershell, this simple Powershell script should give you detail on %path%
$env:Path -split ";" | % {"$(test-path $_);$_"}
generating this kind of output which you can independently verify
True;C:\WINDOWS
True;C:\WINDOWS\system32
True;C:\WINDOWS\System32\Wbem
False;C:windows\System32\windowsPowerShell\v1.0\
False;C:\Program Files (x86)\Java\jre7\bin
to reassemble for updating Path:
$x=$null;foreach ($t in ($env:Path -split ";") ) {if (test-path $t) {$x+=$t+";"}};$x
if 'a' is already a decimal; adding '.' would make 3.4/b(for example) into 3.4./b
Try float(a)/b
Probably you can go with this code to take actions as the checkbox is checked or unchecked.
$('#chk').on('click',function(){
if(this.checked==true){
alert('yes');
}else{
alert('no');
}
});
Try:
SELECT post_datetime
FROM post
WHERE type = 'published'
ORDER BY post_datetime DESC
LIMIT 3
ripgrep
Here is the example using rg
:
rg -N '(?P<p1>.*string1.*)(?P<p2>.*string2.*)' file.txt
It's one of the quickest grepping tools, since it's built on top of Rust's regex engine which uses finite automata, SIMD and aggressive literal optimizations to make searching very fast.
Use it, especially when you're working with a large data.

There are a couple of issues with the above solutions. If you are using, for example, a UISplitViewController
, the master view will always return true for
if(viewController.isViewLoaded && viewController.view.window) {
//Always true for master view in split view controller
}
Instead, take this simple approach which seems to work well in most, if not all cases:
- (void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
//We are now invisible
self.visible = false;
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
//We are now visible
self.visible = true;
}
As of the comment: You should be able to use Apache Commons ReverseListIterator
Iterable<String> reverse
= new IteratorIterable(new ReverseListIterator(stringList));
for(String string: reverse ){
//...do something
}
As @rogerdpack said, you need to wrap the ReverseListIterator
as an Iterable
.
Here is a solution using dplyr >= 0.5
.
library(dplyr)
set.seed(123)
df <- data.frame(
x = sample(0:1, 10, replace = T),
y = sample(0:1, 10, replace = T),
z = 1:10
)
> df %>% distinct(x, y, .keep_all = TRUE)
x y z
1 0 1 1
2 1 0 2
3 1 1 4
In my own case, i did the following:
chmod 400 <key.pem>
ssh -i <key.pem> ec2-user@ec2_public_dns (for debian)
I was initially using root@
part and i got this prompt:
Please login as the user "ec2-user" rather than the user "root".
if(stop = true)
should be if(stop == true)
, or simply (better!) if(stop)
.
This is actually a good opportunity to see a reason to why always use if(something)
if you want to see if it's true
instead of writing if(something == true)
(bad style!).
By doing stop = true
then you are assigning true
to stop
and not comparing.
So why the code below the if
statement executed?
See the JLS - 15.26. Assignment Operators:
At run time, the result of the assignment expression is the value of the variable after the assignment has occurred. The result of an assignment expression is not itself a variable.
So because you wrote stop = true
, then you're satisfying the if
condition.
Expanding on user187291's post, you could also use getters/setters to get around having to use functions.
var x = 1;
var ref = {
get x() { return x; },
set x(v) { x = v; }
};
(ref.x)++;
console.log(x); // prints '2'
x--;
console.log(ref.x); // prints '1'
For enter event handling you can use
@keyup.enter
or@keyup.13
13 is the keycode of enter. For @ key event, the keycode is 50. So you can use @keyup.50
.
For example:
<input @keyup.50="atPress()" />
for k, m in self.materials.items():
example:
miles_dict = {'Monday':1, 'Tuesday':2.3, 'Wednesday':3.5, 'Thursday':0.9}
for k, v in miles_dict.items():
print("%s: %s" % (k, v))
You can use Decode
as well:
SELECT DISTINCT a.item, decode(b.salesman,'VIKKIE','ICKY',Else),NVL(a.manufacturer,'Not Set')Manufacturer
FROM inv_items a, arv_sales b
WHERE a.co = b.co
AND A.ITEM_KEY = b.item_key
AND a.co = '100'
AND a.item LIKE 'BX%'
AND b.salesman in ('01','15')
AND trans_date BETWEEN to_date('010113','mmddrr')
and to_date('011713','mmddrr')
GROUP BY a.item, b.salesman, a.manufacturer
ORDER BY a.item
You are sure you are linking to the same file and then editing that same file?
On some browser, you can use CTRL F5 to force a refresh (on the PC). On the Mac, it is Cmd Shift R
Firebug also has a net tab with "Disable Browser Cache".
But I want to give a warning here: even if you can hard refresh, how do you know your customers are getting the latest version? So you need to check, rather than just making sure you and your program manager can do a hard refresh and just go home and take the paycheck next month. If you want to do a job that change the world for the better, or leave the world a little bit better than you found it, you need to investigate more to make sure it works for your customers too (or else, sometimes the customer may call tech support, and tech support may read the script of "clear out the cookies and it will work", which is what happens to me sometimes). Some methods down at the bottom of this post can ensure the customers get the latest version.
If you are using Chrome and the DevTools is open, you can click and hold the Refresh icon in front of the address bar, and a box will pop up, and you can choose to "Hard Reload" or even "Empty Cache and Hard Reload":
If you use the Google Chrome debugger, it is the same, you can go to the Network section and make sure the "Disable cache (while DevTools is open)" is checked, in the Settings of the debugger panel.
Also, when you link the JavaScript file, use
<script src="my-js-file.js?v=1"></script>
or v=2
, and so forth, when you definitely want to refresh the file. Or you can go to the console and do a Date.now()
and get a timestamp, such as 1491313943549
, and use
<script src="my-js-file.js?t=1491313943549"></script>
Some building tools will do that automatically for you, or can be configured to do that, making it something like:
<script src="main.742a4952.js"></script>
which essentially will bust the cache.
Note that when you use the v=2
or t=1491313943549
, or main.742a4952.js
, you also have the advantage that for your users, they definitely will get the newer version as well.
Finally found in http://viralpatel.net/blogs/2009/09/setting-height-selectbox-combobox-ie.html a simple solution (at least for IE8):
font-size: 1.0em;
BTW, for Google Chrome, found this workaround at How to standardize the height of a select box between Chrome and Firefox? */
-webkit-appearance: menulist-button;
With BeautifulStoneSoup
gone in bs4
, it's even simpler in Python3
from bs4 import BeautifulSoup
soup = BeautifulSoup(html)
text = soup.get_text()
print(text)
To remove the column from table you have to run following migration:
rails g migration remove_column_name_from_table_name column_name:data_type
Then run command:
rake db:migrate
You can escape the "space" char by putting a \ right before it.
I'm using SSMS 2008 version 10.0.5500.0. In this version as part of the Generate Scripts wizard, instead of an Advanced button, there is the screen below. In this case, I wanted just the data inserted and no create statements, so I had to change the two circled properties
This is what works me for the current version of retrofit
2.6.2,
First of all, we need to add a Scalars Converter to the list of our Gradle dependencies, which would take care of converting java.lang.String objects to text/plain request bodies,
implementation'com.squareup.retrofit2:converter-scalars:2.6.2'
Then, we need to pass a converter factory to our Retrofit builder. It will later tell Retrofit how to convert the @Body parameter passed to the service.
private val retrofitBuilder: Retrofit.Builder by lazy {
Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(ScalarsConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
}
Note: In my retrofit builder i have two converters
Gson
andScalars
you can use both of them but to send Json body we need to focusScalars
so if you don't needGson
remove it
Then Retrofit service with a String body parameter.
@Headers("Content-Type: application/json")
@POST("users")
fun saveUser(@Body user: String): Response<MyResponse>
Then create the JSON body
val user = JsonObject()
user.addProperty("id", 001)
user.addProperty("name", "Name")
Call your service
RetrofitService.myApi.saveUser(user.toString())
Instead of creating too many short Polyline
s just create one like here:
PolylineOptions options = new PolylineOptions().width(5).color(Color.BLUE).geodesic(true);
for (int z = 0; z < list.size(); z++) {
LatLng point = list.get(z);
options.add(point);
}
line = myMap.addPolyline(options);
I'm also not sure you should use geodesic
when your points are so close to each other.
This problem becomes apparent when you try to host a react app in github pages.
How I fixed this,
In in my main application file, called app.tsx
, where I include the router.
I set the basename, eg,
<BrowserRouter basename="/Seans-TypeScript-ReactJS-Redux-Boilerplate/">
Note that it is a relative url, this completely simplifies the ability to run locally and hosted. The basename value, matches the repository title on GitHub. This is the path that GitHub pages will auto create.
That is all I needed to do.
See working example hosted on GitHub pages at
https://sean-bradley.github.io/Seans-TypeScript-ReactJS-Redux-Boilerplate/
Check that the date you are trying to set it to lies within the allowed date range if the minDate or maxDate options are set.
As many have pointed out, emacspeak has been the enduring solution cross platform for many of the older hackers out there. Since it supports Linux and Mac out of the box, it has become my prefered means of developing Windows egnostic projects.
To the issue of actually getting down syntax through an auditory one as opposed to a visual one, I have found that there exists a variety of techniques to get one close if not on the same playing field.
Auditory icons can stand in place for verbal descriptors for one example. You can, put tones for how far a line is indented. The longer the tone, the further the indent. Since tones can play in parallel with text to speech, the information comes through in the same timeframe and doesn't serialize the communication of something so basic.
Braille can quickly and precisely decode to the user the exact syntax of a line. This is something more useful for people who use braille in daily life; the biggest advantage is random access to the contents of the display. Refreshable units typically have router keys above each character cell which can place the cursor to that cell. No fiddling with arrow keys O(n) op vs O(1) access.
Auditory dimensionality (pitch, rate, volume, inflection, richness, stress, etc) can convey a concept (keyword, class, variable, error, etc). For example, comments can be read in a monotone inflection...suiting, if I might say so :).
Emacs and other editors to lesser extents (Visual Studio) allow a coder to peruse a program symantically (next block, fold block, down defun, jump to def, walk up the parse tree, etc). You can very quickly get the "big" picture of the structure of an entire project doing this; with extensions like Cedet, you can get the goodness of VS/Eclipse/etc cross platform and in a textual editor.
Could probably go on and on, but that in a nutshell, is the basis of why a few of us are out there hacking away in industry, adacdemia, or in our basements :).
You need to make sure that you add forward slash before your link to socket.io:
<script src="/socket.io/socket.io.js"></script>
Then in the view/controller just do:
var socket = io.connect()
That should solve your problem.
I had a similar experience.
The error was triggered when I initialize a variable on the driver (master), but then tried to use it on one of the workers. When that happens, Spark Streaming will try to serialize the object to send it over to the worker, and fail if the object is not serializable.
I solved the error by making the variable static.

give width as 0dp to make sure its size is exactly as per its weight this will make sure that even if content of child views get bigger, they'll still be limited to exactly half(according to is weight)

There is a built-in Edit toolbar in the VBA editor that has the Comment Block and Uncomment Block buttons by default, and other useful tools.
If you right-click any toolbar or menu (or go to the View menu > Toolbars), you will see a list of available toolbars (above the "Customize..." option). The Standard toolbar is selected by default. Select the Edit toolbar and the new toolbar will appear, with the Comment Block buttons in the middle.
*This is a simpler option to the ones mentioned.
Simply you can find index name and column names of a particular table using below command
SP_HELPINDEX 'tablename'
It work's for me
EDIT (removed wrong solution). EDIT (to add this other option):
Another way to use it would be subclass QThread since it has protected *sleep methods.
QThread::usleep(unsigned long microseconds);
QThread::msleep(unsigned long milliseconds);
QThread::sleep(unsigned long second);
Here's the code to create your own *sleep method.
#include <QThread>
class Sleeper : public QThread
{
public:
static void usleep(unsigned long usecs){QThread::usleep(usecs);}
static void msleep(unsigned long msecs){QThread::msleep(msecs);}
static void sleep(unsigned long secs){QThread::sleep(secs);}
};
and you call it by doing this:
Sleeper::usleep(10);
Sleeper::msleep(10);
Sleeper::sleep(10);
This would give you a delay of 10 microseconds, 10 milliseconds or 10 seconds, accordingly. If the underlying operating system timers support the resolution.
You need to set the path for the preprocessor to search for these include files, if they are not in the project folder.
You can set the path in VC++ Directories, or in Additional Include Directories. Both are found in project settings.
I experienced the same issue, and found out that the applicationdeployed was of .NET version 3.5, but the Application pool was using .NET 2.0. That caused the problem you described above. Hope it helps someone.
