.sort([("field1",pymongo.ASCENDING), ("field2",pymongo.DESCENDING)])
Python uses key,direction. You can use the above way.
So in your case you can do this
for post in db.posts.find().sort('entities.user_mentions.screen_name',pymongo.ASCENDING):
print post
You cannot straightly query mongodb collections by date components like day or month. But its possible by using the special $where javascript expression
db.mydatabase.mycollection.find({$where : function() { return this.date.getMonth() == 11} })
or simply
db.mydatabase.mycollection.find({$where : 'return this.date.getMonth() == 11'})
(But i prefer the first one)
Check out the below shell commands to get the parts of date
>date = ISODate("2011-09-25T10:12:34Z")
> date.getYear()
111
> date.getMonth()
8
> date.getdate()
25
EDIT:
Use $where only if you have no other choice. It comes with the performance problems. Please check out the below comments by @kamaradclimber and @dcrosta. I will let this post open so the other folks get the facts about it.
and check out the link $where Clauses and Functions in Queries for more info
You can use the $set syntax if you want to set the value of a document to an arbitrary value. This will either update the value if the attribute already exists on the document or create it if it doesn't. If you need to set a single value in a dictionary like you describe, you can use the dot notation to access child values.
If p is the object retrieved:
existing = p['d']['a']
For pymongo versions < 3.0
db.ProductData.update({
'_id': p['_id']
},{
'$set': {
'd.a': existing + 1
}
}, upsert=False, multi=False)
For pymongo versions >= 3.0
db.ProductData.update_one({
'_id': p['_id']
},{
'$set': {
'd.a': existing + 1
}
}, upsert=False)
However if you just need to increment the value, this approach could introduce issues when multiple requests could be running concurrently. Instead you should use the $inc syntax:
For pymongo versions < 3.0:
db.ProductData.update({
'_id': p['_id']
},{
'$inc': {
'd.a': 1
}
}, upsert=False, multi=False)
For pymongo versions >= 3.0:
db.ProductData.update_one({
'_id': p['_id']
},{
'$inc': {
'd.a': 1
}
}, upsert=False)
This ensures your increments will always happen.
First, you have to start mongod server then after in another terminal you have to start mongo shell.
For starting, mongo server
1. If you path is Default path (data/db) simple fired mongod in terminal
2. If your path is not data/db then you command like as follow: mongod --dbpath 'here your path comes' .
For starting mongo shell, Simply fired mongo in another terminal
If you get this waiting for connections on port 27017, then your mongo successfully started.
Hope you can get my point
I encountered another problem that returns the same error.
I used a json string with single quotes :
{
'property': 1
}
But json.loads
accepts only double quotes for json properties :
{
"property": 1
}
json.loads
doesn't accept a final comma:
{
"property": "text",
"property2": "text2",
}
ast
to solve single quote and final comma issuesYou can use ast
(part of standard library for both Python 2 and 3) for this processing. Here is an example :
import ast
# ast.literal_eval() return a dict object, we must use json.dumps to get JSON string
import json
# Single quote to double with ast.literal_eval()
json_data = "{'property': 'text'}"
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property": "text"}
# ast.literal_eval() with double quotes
json_data = '{"property": "text"}'
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property": "text"}
# ast.literal_eval() with final coma
json_data = "{'property': 'text', 'property2': 'text2',}"
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property2": "text2", "property": "text"}
Using ast
will prevent you from single quote and final comma issues by interpet the JSON like Python dictionnary (so you must follow the Python dictionnary syntax). It's a pretty good and safely alternative of eval()
function for literal structures.
Python documentation warned us of using large/complex string :
Warning It is possible to crash the Python interpreter with a sufficiently large/complex string due to stack depth limitations in Python’s AST compiler.
To use json.dumps
with single quotes easily you can use this code:
import ast
import json
data = json.dumps(ast.literal_eval(json_data_single_quote))
ast
documentationIf you frequently edit JSON, you may use CodeBeautify. It helps you to fix syntax error and minify/beautify JSON.
I hope it helps.
I will use collection.save(the_changed_dict)
this way. I've just tested this, and it still works for me. The following is quoted directly from pymongo doc.
:
save(to_save[, manipulate=True[, safe=False[, **kwargs]]])
Save a document in this collection.
If to_save already has an "_id" then an update() (upsert) operation is performed and any existing document with that "_id" is overwritten. Otherwise an insert() operation is performed. In this case if manipulate is True an "_id" will be added to to_save and this method returns the "_id" of the saved document. If manipulate is False the "_id" will be added by the server but this method will return None.
I suggest create a list and append dictionary into it.
x = []
cur = db.dbname.find()
for i in cur:
x.append(i)
print(x)
Now x is a list of dictionary, you can manipulate the same in usual python way.
Follow it...
<form action="index.php" method="POST">
<input type="number" name="array[]" value="1">
<input type="number" name="array[]" value="2">
<input type="number" name="array[]" value="3"> <!--taking array input by input name array[]-->
<input type="number" name="array[]" value="4">
<input type="submit" name="submit">
</form>
<?php
$a=$_POST['array'];
echo "Input :" .$a[3]; // Displaying Selected array Value
foreach ($a as $v) {
print_r($v); //print all array element.
}
?>
<IF id="if-1">
<TIME from="5pm" to="9pm" />
<ELSE>
<something else />
</ELSE>
</IF>
I don't know if this makes any sense to anyone else or it is actually usable in your program, but I would do it like this.
My point of view: You need to have everything related to your "IF" inside your IF-tag, otherwise you won't know what ELSE belongs to what IF. Secondly, I'd skip the THEN tag because it always follows an IF.
You probably want something like:
if data.find('!masters') != -1:
f = open('masters.txt')
lines = f.read().splitlines()
f.close()
for line in lines:
print line
sck.send('PRIVMSG ' + chan + " " + str(line) + '\r\n')
Don't close it every iteration of the loop and print line instead of lines. Also use readlines to get all the lines.
EDIT removed my other answer - the other one in this discussion is a better alternative than what I had, so there's no reason to copy it.
Also stripped off the \n with read().splitlines()
/[^A-Za-z0-9\s]/g should match all punctuation but keep the spaces.
So you can use .replace(/\s{2,}/g, " ")
to replace extra spaces if you need to do so. You can test the regex in http://rubular.com/
.replace(/[^A-Za-z0-9\s]/g,"").replace(/\s{2,}/g, " ")
Update: Will only work if the input is ANSI English.
I was able to solve similar Warning: session_start(): Cannot send session cache limiter - headers already sent
by just removing a space in front of the <?php
tag.
It worked.
I'm pretty sure you shouldn't need to set a position:
$("#dialog").dialog();
I did have a look at the article, and also checked what it says on the official jquery-ui site about positioning a dialog : and in it were discussed 2 states of: initialise and after initialise.
Code examples - (taken from jQuery UI 2009-12-03)
Initialize a dialog with the position option specified.
$('.selector').dialog({ position: 'top' });
Get or set the position option, after init.
//getter
var position = $('.selector').dialog('option', 'position');
//setter
$('.selector').dialog('option', 'position', 'top');
I think that if you were to remove the position attribute you would find it centers by itself else try the second setter option where you define 3 elements of "option" "position" and "center".
i used Mofi sample, and change some parameters, no you can do -t
@%SystemRoot%\system32\ping.exe -n -1 4.2.2.4
The array declaration should be:
Car[] garage = new Car[100];
You can also just assign directly:
garage[1] = new Car("Blue");
It's actually easier than everyone's making it sound... especially if you use the $.ajax({})
base syntax vs. one of the helper functions.
Just pass in the key: value
pair like you would on any object, when you setup your ajax request... (because $(this)
hasn't changed context yet, it's still the trigger for the bind call above)
<script type="text/javascript">
$(".qty input").bind("keypress change", function() {
$.ajax({
url: "/order_items/change/"+$(this).attr("data-order-item-id")+"/qty:"+$(this).val()+"/returnas.json",
type: "POST",
dataType: "json",
qty_input: $(this),
anything_else_i_want_to_pass_in: "foo",
success: function(json_data, textStatus, jqXHR) {
/* here is the input, which triggered this AJAX request */
console.log(this.qty_input);
/* here is any other parameter you set when initializing the ajax method */
console.log(this.anything_else_i_want_to_pass_in);
}
});
});
</script>
One of the reasons this is better than setting the var, is that the var is global and as such, overwritable... if you have 2 things which can trigger ajax calls, you could in theory trigger them faster than ajax call responds, and you'd have the value for the second call passed into the first. Using this method, above, that wouldn't happen (and it's pretty simple to use too).
Do keep in mind that the file.getContentType
could also output application/octet-stream instead of the required application/vnd.openxmlformats-officedocument.spreadsheetml.sheet when you try to upload the file that is already open.
I wrote a little jQuery extension for this:
$.fn.nl2brText = function (sText) {
var bReturnValue = 'undefined' == typeof sText;
if(bReturnValue) {
sText = $('<pre>').html(this.html().replace(/<br[^>]*>/i, '\n')).text();
}
var aElms = [];
sText.split(/\r\n|\r|\n/).forEach(function(sSubstring) {
if(aElms.length) {
aElms.push(document.createElement('br'));
}
aElms.push(document.createTextNode(sSubstring));
});
var $aElms = $(aElms);
if(bReturnValue) {
return $aElms;
}
return this.empty().append($aElms);
};
There is no error message associated with the mail()
function. There is only a true
or false
returned on whether the email was accepted for delivery. Not whether it ultimately gets delivered, but basically whether the domain exists and the address is a validly formatted email address.
You could write a jQuery function which allowed you to add hidden fields to a form:
// This must be applied to a form (or an object inside a form).
jQuery.fn.addHidden = function (name, value) {
return this.each(function () {
var input = $("<input>").attr("type", "hidden").attr("name", name).val(value);
$(this).append($(input));
});
};
And then add the hidden field before you submit:
var frm = $("#form").addHidden('SaveAndReturn', 'Save and Return')
.submit();

Editor's note: this is a very dangerous approach, if you are using a version of PHP old enough to use it. It opens your code to man-in-the-middle attacks and removes one of the primary purposes of an encrypted connection. The ability to do this has been removed from modern versions of PHP because it is so dangerous. The only reason this has been upvoted 70 time is because people are lazy. DO NOT DO THIS.
I know it's a (very) old question and it's about command line, but when I searched Google for "SSL: no alternative certificate subject name matches target host name", this was the first hit.
It took me a good while to figure out the answer so hope this saves someone a lot of time! In PHP add this to your cUrl setopts:
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
p.s: this should be a temporary solution. Since this is a certificate error, best thing is to have the certificate fixed ofcourse!
In Pandas version 1.10 and above you can use parameters xlabel

To append to an array, just use the +=

With jQuery this is working for me :
$('img').error(function() {
$(this).attr('src', '/no-img.png').addClass('no-img');
});
And I can use this picture everywhere on my website regardless of the size of it with the following CSS3 property :
img.no-img {
object-fit: cover;
object-position: 50% 50%;
}
TIP 1 : use a square image of at least 800 x 800 pixels.
TIP 2 : for use with portrait of people, use
object-position: 20% 50%;
For missing background images, I also added the following on each background-image
declaration :
background-image: url('path-to-image.png'), url('no-img.png');
NOTE : not working for transparent images.
Another solution is to detect missing image with Apache before to send to browser and remplace it by the default no-img.png content.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} /images/.*\.(gif|jpg|jpeg|png)$
RewriteRule .* /images/no-img.png [L,R=307]
element = findElement(By.xpath("//*[@test-id='test-username']");
element = findElement(By.xpath("//input[@test-id='test-username']");
(*) - any tagname
header('Location: http://linkhere.com/' . $your_variable);
I would prefer the C++ size constraints over the C versions:
// Ignore to the end of file
cin.ignore(std::numeric_limits<std::streamsize>::max())
// Ignore to the end of line
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n')
Short answer No. CSS is not specific to brands.
Below are the articles to implement for iOS using media only.

Infact you can use PHP, Javascript to detect the iOS browser and according to that you can call CSS file. For instance

Why does it implement its methods? How can it implement its methods when an interface can't contain method body? How can it implement the methods when it extends the other interface and not implement it? What is the purpose of an interface implementing another interface?
Interface does not implement the methods of another interface but just extends them.
One example where the interface extension is needed is: consider that you have a vehicle interface with two methods moveForward
and moveBack
but also you need to incorporate the Aircraft which is a vehicle but with some addition methods like moveUp
, moveDown
so
in the end you have:
public interface IVehicle {
bool moveForward(int x);
bool moveBack(int x);
};
and airplane:
public interface IAirplane extends IVehicle {
bool moveDown(int x);
bool moveUp(int x);
};
Using .NET 4.5 trying to perform form POST file upload. Tried most of the methods above but to no avail. Found the solution here https://www.c-sharpcorner.com/article/upload-any-file-using-http-post-multipart-form-data
But I am not not keen as I do not understand why we still need to deal with such low level programming in these common usages (should be handled nicely by framework)
I had this issue while installing dynamic ax setup in VM, while installing it was showing me to 'licence is not valid, Reinstall visual studio shell 2010 version', so i uninstalled the visual studio shell 2010 version and its following component and tried to install again the AX admin it worked.
In visual studio code i found that simple regex as ^ worked.
You have it reversed. The 100 should be the first parameter (it's the key) and the "one" should be the second parameter (it's the value).
Read the javadoc for HashMap and that might help you: HashMap
To get the value, use hashmap.get(100)
.
Why don't you just use the database diagram functionality built into SQL Server?
You can use a trick to use scopes as you wish, just declare enum in such way:
struct Days
{
enum type
{
Saturday,Sunday,Tuesday,Wednesday,Thursday,Friday
};
};
Days::type day = Days::Saturday;
if (day == Days::Saturday)
It is good practice to make sure the callback is an actual function before attempting to execute it:
if (callback && typeof(callback) === "function") {
callback();
}
It only worked for me in Firefox when accessing it from the window
object.
Example...
window.onload = function()
{
window.localStorage.clear();
}
The simple option is just to set the forms's AcceptButton to the button you want pressed (usually "OK" etc):
TextBox tb = new TextBox();
Button btn = new Button { Dock = DockStyle.Bottom };
btn.Click += delegate { Debug.WriteLine("Submit: " + tb.Text); };
Application.Run(new Form { AcceptButton = btn, Controls = { tb, btn } });
If this isn't an option, you can look at the KeyDown event etc, but that is more work...
TextBox tb = new TextBox();
Button btn = new Button { Dock = DockStyle.Bottom };
btn.Click += delegate { Debug.WriteLine("Submit: " + tb.Text); };
tb.KeyDown += (sender,args) => {
if (args.KeyCode == Keys.Return)
{
btn.PerformClick();
}
};
Application.Run(new Form { Controls = { tb, btn } });
I know this is an old topic but I just wanted to add a solution that wasn't suggested yet.
I had the same problem with a resource file. I edited it outside Visual Studio and the designer file hadn't updated properly.
Renaming the file did the trick of regenerating the Designer file. I just renamed it to the initial name again and that worked just fine!
My bad, in trying to simplify it, I went too far, actually stuffs
is a record of all kinds of info, I just want the id in it.
stuffs = [[123, first, last], [456, first, last]]
I want my_sting
to be
my_sting = '123, 456'
My original code should have looked like this:
{% set my_string = '' %}
{% for stuff in stuffs %}
{% set my_string = my_string + stuff.id + ', '%}
{% endfor%}
Thinking about it, stuffs
is probably a dictionary, but you get the gist.
Yes I found the join
filter, and was going to approach it like this:
{% set my_string = [] %}
{% for stuff in stuffs %}
{% do my_string.append(stuff.id) %}
{% endfor%}
{% my_string|join(', ') %}
But the append doesn't work without importing the extensions to do it, and reading that documentation gave me a headache. It doesn't explicitly say where to import it from or even where you would put the import statement, so I figured finding a way to concat would be the lesser of the two evils.
$("#grid_GridHeader:first")
works as well.
cache:true
only works with GET and HEAD request.
You could roll your own solution as you said with something along these lines :
var localCache = {
data: {},
remove: function (url) {
delete localCache.data[url];
},
exist: function (url) {
return localCache.data.hasOwnProperty(url) && localCache.data[url] !== null;
},
get: function (url) {
console.log('Getting in cache for url' + url);
return localCache.data[url];
},
set: function (url, cachedData, callback) {
localCache.remove(url);
localCache.data[url] = cachedData;
if ($.isFunction(callback)) callback(cachedData);
}
};
$(function () {
var url = '/echo/jsonp/';
$('#ajaxButton').click(function (e) {
$.ajax({
url: url,
data: {
test: 'value'
},
cache: true,
beforeSend: function () {
if (localCache.exist(url)) {
doSomething(localCache.get(url));
return false;
}
return true;
},
complete: function (jqXHR, textStatus) {
localCache.set(url, jqXHR, doSomething);
}
});
});
});
function doSomething(data) {
console.log(data);
}
EDIT: as this post becomes popular, here is an even better answer for those who want to manage timeout cache and you also don't have to bother with all the mess in the $.ajax() as I use $.ajaxPrefilter(). Now just setting {cache: true}
is enough to handle the cache correctly :
var localCache = {
/**
* timeout for cache in millis
* @type {number}
*/
timeout: 30000,
/**
* @type {{_: number, data: {}}}
**/
data: {},
remove: function (url) {
delete localCache.data[url];
},
exist: function (url) {
return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
},
get: function (url) {
console.log('Getting in cache for url' + url);
return localCache.data[url].data;
},
set: function (url, cachedData, callback) {
localCache.remove(url);
localCache.data[url] = {
_: new Date().getTime(),
data: cachedData
};
if ($.isFunction(callback)) callback(cachedData);
}
};
$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
if (options.cache) {
var complete = originalOptions.complete || $.noop,
url = originalOptions.url;
//remove jQuery cache as we have our own localCache
options.cache = false;
options.beforeSend = function () {
if (localCache.exist(url)) {
complete(localCache.get(url));
return false;
}
return true;
};
options.complete = function (data, textStatus) {
localCache.set(url, data, complete);
};
}
});
$(function () {
var url = '/echo/jsonp/';
$('#ajaxButton').click(function (e) {
$.ajax({
url: url,
data: {
test: 'value'
},
cache: true,
complete: doSomething
});
});
});
function doSomething(data) {
console.log(data);
}
And the fiddle here CAREFUL, not working with $.Deferred
Here is a working but flawed implementation working with deferred:
var localCache = {
/**
* timeout for cache in millis
* @type {number}
*/
timeout: 30000,
/**
* @type {{_: number, data: {}}}
**/
data: {},
remove: function (url) {
delete localCache.data[url];
},
exist: function (url) {
return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
},
get: function (url) {
console.log('Getting in cache for url' + url);
return localCache.data[url].data;
},
set: function (url, cachedData, callback) {
localCache.remove(url);
localCache.data[url] = {
_: new Date().getTime(),
data: cachedData
};
if ($.isFunction(callback)) callback(cachedData);
}
};
$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
if (options.cache) {
//Here is our identifier for the cache. Maybe have a better, safer ID (it depends on the object string representation here) ?
// on $.ajax call we could also set an ID in originalOptions
var id = originalOptions.url+ JSON.stringify(originalOptions.data);
options.cache = false;
options.beforeSend = function () {
if (!localCache.exist(id)) {
jqXHR.promise().done(function (data, textStatus) {
localCache.set(id, data);
});
}
return true;
};
}
});
$.ajaxTransport("+*", function (options, originalOptions, jqXHR, headers, completeCallback) {
//same here, careful because options.url has already been through jQuery processing
var id = originalOptions.url+ JSON.stringify(originalOptions.data);
options.cache = false;
if (localCache.exist(id)) {
return {
send: function (headers, completeCallback) {
completeCallback(200, "OK", localCache.get(id));
},
abort: function () {
/* abort code, nothing needed here I guess... */
}
};
}
});
$(function () {
var url = '/echo/jsonp/';
$('#ajaxButton').click(function (e) {
$.ajax({
url: url,
data: {
test: 'value'
},
cache: true
}).done(function (data, status, jq) {
console.debug({
data: data,
status: status,
jqXHR: jq
});
});
});
});

git commit
And your default editor has been launched. In the worst case scenario (for you) it could have been vim :)
If you don't know how to quit vim, use :q.
If you have further problems, you could use
git commit -m 'Type your commit message here'
Git. Switch to another branch
git checkout branch_name
Allowing all certificates is very powerful but it could also be dangerous. If you would like to only allow valid certificates plus some certain certificates it could be done like this.
.Net core:
using (var httpClientHandler = new HttpClientHandler())
{
httpClientHandler.ServerCertificateCustomValidationCallback = (message, cert, chain, sslPolicyErrors) => {
if (sslPolicyErrors == SslPolicyErrors.None)
{
return true; //Is valid
}
if (cert.GetCertHashString() == "99E92D8447AEF30483B1D7527812C9B7B3A915A7")
{
return true;
}
return false;
};
using (var httpClient = new HttpClient(httpClientHandler))
{
var httpResponse = httpClient.GetAsync("https://example.com").Result;
}
}
.Net framework:
System.Net.ServicePointManager.ServerCertificateValidationCallback += delegate (
object sender,
X509Certificate cert,
X509Chain chain,
SslPolicyErrors sslPolicyErrors)
{
if (sslPolicyErrors == SslPolicyErrors.None)
{
return true; //Is valid
}
if (cert.GetCertHashString() == "99E92D8447AEF30483B1D7527812C9B7B3A915A7")
{
return true;
}
return false;
};
Update:
How to get cert.GetCertHashString()
value in Chrome:
Click on Secure
or Not Secure
in the address bar.
Then click on Certificate -> Details -> Thumbprint and copy the value. Remember to do cert.GetCertHashString().ToLower()
.

An easy way to login with a HTTP POST without doing any Base64 specific calls is to use the HTTPClient BasicCredentialsProvider
import java.io.IOException;
import static java.lang.System.out;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.HttpClientBuilder;
//code
CredentialsProvider provider = new BasicCredentialsProvider();
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(user, password);
provider.setCredentials(AuthScope.ANY, credentials);
HttpClient client = HttpClientBuilder.create().setDefaultCredentialsProvider(provider).build();
HttpResponse response = client.execute(new HttpPost("http://address/test/login"));//Replace HttpPost with HttpGet if you need to perform a GET to login
int statusCode = response.getStatusLine().getStatusCode();
out.println("Response Code :"+ statusCode);
Try removing the float

If your button still doesn't show anything with title

Use this way and check all parts :
from __future__ import absolute_import, division, print_function, unicode_literals
import numpy as np
import tensorflow as tf
import tensorflow_hub as hub
import tensorflow_datasets as tfds
version = tf.__version__
executing_eagerly = tf.executing_eagerly()
hub_version = hub.__version__
available = tf.config.experimental.list_physical_devices("GPU")
print("Version: ", version)
print("Eager mode: ", executing_eagerly)
print("Hub Version: ", h_version)
print("GPU is", "available" if avai else "NOT AVAILABLE")
I had the same error but in my case it was not related to nuget packages at all. My solution had project that had reference to other projects that were not a part of my solution and were not built. After building them with some other solution (or I could include them into my solution as well), AND re-opening my solution in visual studio the issue was resolved.
One clarification (and a point that confused me):
"remotes/origin/HEAD is the default branch" is not really correct.
remotes/origin/master was the default branch in the remote repository (last time you checked). HEAD is not a branch, it just points to a branch.
Think of HEAD as your working area. When you think of it this way then 'git checkout branchname' makes sense with respect to changing your working area files to be that of a particular branch. You "checkout" branch files into your working area. HEAD for all practical purposes is what is visible to you in your working area.
I've tried the above answers but could not get them to work. The only code that worked for me was $window.location.search = ''
If you are using webjars. You need to add this in your configure
method:
http.authorizeRequests().antMatchers("/webjars/**").permitAll();
Make sure this is the first statement. For example:
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/webjars/**").permitAll();
http.authorizeRequests().anyRequest().authenticated();
http.formLogin()
.loginPage("/login")
.failureUrl("/login?error")
.usernameParameter("email")
.permitAll()
.and()
.logout()
.logoutUrl("/logout")
.deleteCookies("remember-me")
.logoutSuccessUrl("/")
.permitAll()
.and()
.rememberMe();
}
You will also need to have this in order to have webjars enabled:
@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {
...
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
...
}
You need to use the cURL library to send this request.
<?php
// Your ID and token
$blogID = '8070105920543249955';
$authToken = 'OAuth 2.0 token here';
// The data to send to the API
$postData = array(
'kind' => 'blogger#post',
'blog' => array('id' => $blogID),
'title' => 'A new post',
'content' => 'With <b>exciting</b> content...'
);
// Setup cURL
$ch = curl_init('https://www.googleapis.com/blogger/v3/blogs/'.$blogID.'/posts/');
curl_setopt_array($ch, array(
CURLOPT_POST => TRUE,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_HTTPHEADER => array(
'Authorization: '.$authToken,
'Content-Type: application/json'
),
CURLOPT_POSTFIELDS => json_encode($postData)
));
// Send the request
$response = curl_exec($ch);
// Check for errors
if($response === FALSE){
die(curl_error($ch));
}
// Decode the response
$responseData = json_decode($response, TRUE);
// Close the cURL handler
curl_close($ch);
// Print the date from the response
echo $responseData['published'];
If, for some reason, you can't/don't want to use cURL, you can do this:
<?php
// Your ID and token
$blogID = '8070105920543249955';
$authToken = 'OAuth 2.0 token here';
// The data to send to the API
$postData = array(
'kind' => 'blogger#post',
'blog' => array('id' => $blogID),
'title' => 'A new post',
'content' => 'With <b>exciting</b> content...'
);
// Create the context for the request
$context = stream_context_create(array(
'http' => array(
// http://www.php.net/manual/en/context.http.php
'method' => 'POST',
'header' => "Authorization: {$authToken}\r\n".
"Content-Type: application/json\r\n",
'content' => json_encode($postData)
)
));
// Send the request
$response = file_get_contents('https://www.googleapis.com/blogger/v3/blogs/'.$blogID.'/posts/', FALSE, $context);
// Check for errors
if($response === FALSE){
die('Error');
}
// Decode the response
$responseData = json_decode($response, TRUE);
// Print the date from the response
echo $responseData['published'];
f = open('file.txt', 'r')
print f.read()
f.close()
From http://docs.python.org/tutorial/inputoutput.html
To read a file’s contents, call f.read(size), which reads some quantity of data and returns it as a string. size is an optional numeric argument. When size is omitted or negative, the entire contents of the file will be read and returned; it’s your problem if the file is twice as large as your machine’s memory. Otherwise, at most size bytes are read and returned. If the end of the file has been reached, f.read() will return an empty string ("").
Make sure you wrap your "row" inside the class "container" . Also add reference to bootstrap in your html.
Something like this should work:

You have to move the css
folder into your web
folder. It seems that your web
folder on the hard drive equals the /ServletApp
folder as seen from the www. Other content than inside your web
folder cannot be accessed from the browsers.
The url of the CSS link is then
<link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>
Since Chrome 32 you have the CSS media
option in the Screen
section of the drawer Emulation
tab.
Just enable it, select print
as the target media type, and - behold - your page is rendered [almost] the way it will be printed.
Use Esc to bring up the drawer if it's not visible.
The link below will demonstrate how I accomplished this. Not very hard - just have to use some clever front-end dev!!
<div style="position: fixed; bottom: 0%; top: 0%;">
<div style="overflow-y: scroll; height: 100%;">
Menu HTML goes in here
</div>

Just in case if this helps anybody.
Python version: 3.7.7 platform: Ubuntu 18.04.4 LTS
This came with default python version 3.6.9, however I had installed my own 3.7.7 version python on it (installed building it from source)
tkinter was not working even when the help('module')
shows tkinter in the list.
The following steps worked for me:
sudo apt-get install tk-dev.
rebuild the python: 1. Navigate to your python folder and run the checks:
cd Python-3.7.7
sudo ./configure --enable-optimizations
sudo make -j 8
--- here 8 are the number of processors, check yours using nproc
command.Installing using:
sudo make altinstall
Don't use sudo make install, it will overwrite default 3.6.9 version, which might be messy later.
python3.7 -m tkinter
A windows box will pop up, your tkinter is ready now.
int cores = Runtime.getRuntime().availableProcessors();
If cores
is less than one, either your processor is about to die, or your JVM has a serious bug in it, or the universe is about to blow up.
I clicked the "Deny" button, and the keychain was off.
I locked the keychain:
And then I entered the login keychain again.
When you specify -jar
then the -cp
parameter will be ignored.
From the documentation:
When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored.
You also cannot "include" needed jar files into another jar file (you would need to extract their contents and put the .class files into your jar file)
You have two options:
lib
directory into the manifest (you can use relative paths there)-cp
: java -cp MyJar.jar:lib/* com.somepackage.subpackage.Main
When your are trying to apply prod on string type of value like:
['-214' '-153' '-58' ..., '36' '191' '-37']
you will get the error.
Solution:
Append only integer value like [1,2,3]
, and you will get your expected output.
If the value is in string format before appending then, in the array you can convert the type into int
type and store it in a list
.
you can do this without jQuery:
var form=document.getElementById('form-id');//retrieve the form as a DOM element
var input = document.createElement('input');//prepare a new input DOM element
input.setAttribute('name', inputName);//set the param name
input.setAttribute('value', inputValue);//set the value
input.setAttribute('type', inputType)//set the type, like "hidden" or other
form.appendChild(input);//append the input to the form
form.submit();//send with added input
You can create a custom encoder that returns a list
when it encounters a set
. Here's an example:
>>> import json
>>> class SetEncoder(json.JSONEncoder):
... def default(self, obj):
... if isinstance(obj, set):
... return list(obj)
... return json.JSONEncoder.default(self, obj)
...
>>> json.dumps(set([1,2,3,4,5]), cls=SetEncoder)
'[1, 2, 3, 4, 5]'
You can detect other types this way too. If you need to retain that the list was actually a set, you could use a custom encoding. Something like return {'type':'set', 'list':list(obj)}
might work.
To illustrated nested types, consider serializing this:
>>> class Something(object):
... pass
>>> json.dumps(set([1,2,3,4,5,Something()]), cls=SetEncoder)
This raises the following error:
TypeError: <__main__.Something object at 0x1691c50> is not JSON serializable
This indicates that the encoder will take the list
result returned and recursively call the serializer on its children. To add a custom serializer for multiple types, you can do this:
>>> class SetEncoder(json.JSONEncoder):
... def default(self, obj):
... if isinstance(obj, set):
... return list(obj)
... if isinstance(obj, Something):
... return 'CustomSomethingRepresentation'
... return json.JSONEncoder.default(self, obj)
...
>>> json.dumps(set([1,2,3,4,5,Something()]), cls=SetEncoder)
'[1, 2, 3, 4, 5, "CustomSomethingRepresentation"]'
If you want to find interactively logged on users, I found a great tip here :https://p0w3rsh3ll.wordpress.com/2012/02/03/get-logged-on-users/ (Win32_ComputerSystem did not help me)
$explorerprocesses = @(Get-WmiObject -Query "Select * FROM Win32_Process WHERE Name='explorer.exe'" -ErrorAction SilentlyContinue)
If ($explorerprocesses.Count -eq 0)
{
"No explorer process found / Nobody interactively logged on"
}
Else
{
ForEach ($i in $explorerprocesses)
{
$Username = $i.GetOwner().User
$Domain = $i.GetOwner().Domain
Write-Host "$Domain\$Username logged on since: $($i.ConvertToDateTime($i.CreationDate))"
}
}
Use __time function:
${__time(dd/MM/yyyy,)}
${__time(hh:mm a,)}
Since JMeter 3.3, there are two new functions that let you compute a time:
"The timeShift function returns a date in the given format with the specified amount of seconds, minutes, hours, days or months added" and
"The RandomDate function returns a random date that lies between the given start date and end date values."
Since JMeter 4.0:
Convert a date or time from source to target format
If you're looking to learn jmeter correctly, this book will help you.
Moreover to convert whatever you want, you can use QVariant
.
For an int
to a QString
you get:
QVariant(3).toString();
A float
to a string
or a string
to a float
:
QVariant(3.2).toString();
QVariant("5.2").toFloat();
csvreader.next() Return the next row of the reader’s iterable object as a list, parsed according to the current dialect.
<Grid x:Name="outerGrid">
<Grid x:Name="innerGrid">
<Border BorderBrush="#FF179AC8" BorderThickness="2" />
<other stuff></other stuff>
<other stuff></other stuff>
</Grid>
</Grid>
This code Wrap a border inside the "innerGrid"
Beyond what's been said already about selectors, you may want to look at the NSInvocation class.
An NSInvocation is an Objective-C message rendered static, that is, it is an action turned into an object. NSInvocation objects are used to store and forward messages between objects and between applications, primarily by NSTimer objects and the distributed objects system.
An NSInvocation object contains all the elements of an Objective-C message: a target, a selector, arguments, and the return value. Each of these elements can be set directly, and the return value is set automatically when the NSInvocation object is dispatched.
Keep in mind that while it's useful in certain situations, you don't use NSInvocation in a normal day of coding. If you're just trying to get two objects to talk to each other, consider defining an informal or formal delegate protocol, or passing a selector and target object as has already been mentioned.
In Laravel Version - 4, HTML and Form existed, but not now.
Why:
The only reason is they have collected some user requirements and they want it more lightweight and so they removed it as in the sense that a user can add it manually.
What to do to add HTML & Forms in Laravel 5.2 or 5.3:
For 5.2:
Go to the Laravel Collective site and installation processes have demonstrated their.
Like for 5.2: on the command line, run the command
composer require "laravelcollective/html":"^5.2.0"
Then, in the provider array which is in config/app.php. Add this line at last using a comma(,):
Collective\Html\HtmlServiceProvider::class,
For using HTML and FORM text we need to alias them in the aliases array of config/app.php. Add the two lines at the last
'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,
And for 5.3:
Just run the command
composer require "laravelcollective/html":"^5.3.0"
And the rest of the procedure is like 5.2.
Then you can use Laravel Form and other HTML links in your projects. For this, follow this documentation:
5.2: https://laravelcollective.com/docs/5.2/html
5.3: https://laravelcollective.com/docs/5.3/html
Demo Code:
To open a form, open and close a tag:
{!! Form::open(['url' => 'foo/bar']) !!}
{!! Form::close() !!}
And for creating label and input text with a Bootstrap form-control class and other use:
{!! Form::label('title', 'Post Title') !!}
{!! Form::text('title', null, array('class' => 'form-control')) !!}
And for more, use the documentation, https://laravelcollective.com/.
You will need to get the textbox via javascript when moving the mouse over it and change its type
to text
. And when moving it out, you will want to change it back to password
. No chance of doing this in pure CSS.
HTML:
<input type="password" name="password" id="myPassword" size="30" />
<img src="theicon" onmouseover="mouseoverPass();" onmouseout="mouseoutPass();" />
JS:
function mouseoverPass(obj) {
var obj = document.getElementById('myPassword');
obj.type = "text";
}
function mouseoutPass(obj) {
var obj = document.getElementById('myPassword');
obj.type = "password";
}
For small projects I find it easiest to work with tuples. When that gets too hard to manage (and not before) I start grouping things into logical structures, however I think your suggested use of dictionaries and ReturnValue
objects is wrong (or too simplistic).
Returning a dictionary with keys "y0"
, "y1"
, "y2"
, etc. doesn't offer any advantage over tuples. Returning a ReturnValue
instance with properties .y0
, .y1
, .y2
, etc. doesn't offer any advantage over tuples either. You need to start naming things if you want to get anywhere, and you can do that using tuples anyway:
def get_image_data(filename):
[snip]
return size, (format, version, compression), (width,height)
size, type, dimensions = get_image_data(x)
IMHO, the only good technique beyond tuples is to return real objects with proper methods and properties, like you get from re.match()
or open(file)
.

}
The first line of new text view is unnecessary
t=new TextView(this);
you can just do this
TextView t = (TextView)findViewById(R.id.TextView01);
as far as a background thread that sleeps here is an example, but I think there is a timer that would be better for this. here is a link to a good example using a timer instead http://android-developers.blogspot.com/2007/11/stitch-in-time.html
Thread thr = new Thread(mTask);
thr.start();
}
Runnable mTask = new Runnable() {
public void run() {
// just sleep for 30 seconds.
try {
Thread.sleep(3000);
runOnUiThread(done);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};
Runnable done = new Runnable() {
public void run() {
// t.setText("done");
}
};
Note that besides all other comments there is a small difference, which should be mentioned here for completeness!
With the empty catch clause you can catch non-CLSCompliant Exceptions when the assembly is marked with "RuntimeCompatibility(WrapNonExceptionThrows = false)" (which is true by default since CLR2). [1][2][3]

the problem is that href is href="#" you must remove href="#" in all tag
Use Mach-OView for viewing all the Symbols in dylib
First, check the dependency hierarchy than to exclude all slf4j jars from other dependencies and add separate slf4j as dependencies.
If for some reason you have position absolute on the div, do this:
<div class="something"></div>
.something {
position:absolute;
left:0;
right:0;
margin-left:auto;
margin-right:auto;
}
I had a similar problem with 'org.codehaus.mojo'-'jaxws-maven-plugin': could not resolve dependencies. Fortunately, I was able to do a Project > Clean in Eclipse, which resolved the issue.
You cannot achieve the desired solution with CSS z-index either, as z-index is only relative to the parent element. So if you have parents A and B with respective children a and b, b's z-index is only relative to other children of B and a's z-index is only relative to other children of A.
The z-index of A and B are relative to each other if they share the same parent element, but all of the children of one will share the same relative z-index at this level.
The above answers are wrong, respectively aren't answering why you're having troubles viewing the demo-content prod-mode.
Here's the correct answer: clear your "prod"-cache:
php app/console cache:clear --env prod
Run this command in the terminal:
docker ps
If docker is not running, you wil get this message:
Error response from daemon: dial unix docker.raw.sock: connect: connection refused
Here is a working example :
document.cookie = "testCookie=cookieval; domain=." +
location.hostname.split('.').reverse()[1] + "." +
location.hostname.split('.').reverse()[0] + "; path=/"
This is a generic solution that takes the root domain from the location object and sets the cookie. The reversing is because you don't know how many subdomains you have if any.
When you try to handle multi languages like Japanese and Korean you might get in trouble. mb_convert_encoding with 'auto' parameter doesn't work well. Setting mb_detect_order('ASCII,UTF-8,JIS,EUC-JP,SJIS,EUC-KR,UHC') doesn't help since it will detect EUC-* wrongly.
I concluded that as long as input strings comes from HTML, it should use 'charset' in a meta element. I use Simple HTML DOM Parser because it supports invalid HTML.
The below snippet extracts title element from a web page. If you would like to convert entire page, then you may want to remove some lines.
<?php
require_once 'simple_html_dom.php';
echo convert_title_to_utf8(file_get_contents($argv[1])), PHP_EOL;
function convert_title_to_utf8($contents)
{
$dom = str_get_html($contents);
$title = $dom->find('title', 0);
if (empty($title)) {
return null;
}
$title = $title->plaintext;
$metas = $dom->find('meta');
$charset = 'auto';
foreach ($metas as $meta) {
if (!empty($meta->charset)) { // html5
$charset = $meta->charset;
} else if (preg_match('@charset=(.+)@', $meta->content, $match)) {
$charset = $match[1];
}
}
if (!in_array(strtolower($charset), array_map('strtolower', mb_list_encodings()))) {
$charset = 'auto';
}
return mb_convert_encoding($title, 'UTF-8', $charset);
}
In Bootstrap, the .btn
class has a white-space: nowrap;
property, making it so that the button text won't wrap. So, after setting that to normal
, and giving the button a width
, the text should wrap to the next line if the text would exceed the set width
.
#new-board-btn {
white-space: normal;
}
Either of the latter two, since val
could potentially be of a type that defines __eq__()
to return true when passed None
.
Copy the folder, firefox.exe is in and place in the c:\ only. The script is having a hard time climbing your file tree. I found that when I placed the *.exe file in the c:\ it eliminated the error message " file not found."
If you're using guava (and you should be, see effective java item #15):
ImmutableList<String> list = ImmutableList.copyOf(s.split(","));
This is a variation of something I learned several years back. Apparently, this is popular with C++ developers.
First off, I think I know why you want to break out of IF blocks. For me, I don't like a bunch of nested blocks because 1) it makes the code look messy and 2) it can be a pia to maintain if you have to move logic around.
Consider a do/while
loop instead:
public void Method()
{
bool something = true, something2 = false;
do
{
if (!something) break;
if (something2) break;
} while (false);
}
The do/while
loop is guaranteed to run only once just like an IF block thanks to the hardcoded false
condition. When you want to exit early, just break
.
Based on my personal experience with this knowledge base software, I would also like to join 'Julien H.' in suggesting PHPKB from http://www.knowledgebase-script.com
Personally I believe its one of the best. Many features, continously developed, excellent support & the GUI is just simple & great.

if(BaseGet(responseString) != null)
{
BaseRemoveAt(BaseIndexOf(BaseGet(responseString)));
}
BaseAdd(value);
}
}
protected override System.Configuration.ConfigurationElement CreateNewElement()
{
return new Company();
}
protected override object GetElementKey(System.Configuration.ConfigurationElement element)
{
return ((Company)element).Name;
}
}
and ConfigurationSection:
public class RegisterCompaniesConfig
: ConfigurationSection
{
public static RegisterCompaniesConfig GetConfig()
{
return (RegisterCompaniesConfig)System.Configuration.ConfigurationManager.GetSection("RegisterCompanies") ?? new RegisterCompaniesConfig();
}
[System.Configuration.ConfigurationProperty("Companies")]
[ConfigurationCollection(typeof(Companies), AddItemName = "Company")]
public Companies Companies
{
get
{
object o = this["Companies"];
return o as Companies ;
}
}
}
and you must also register your new configuration section in web.config (app.config):
<configuration>
<configSections>
<section name="Companies" type="blablabla.RegisterCompaniesConfig" ..>
then you load your config with
var config = RegisterCompaniesConfig.GetConfig();
foreach(var item in config.Companies)
{
do something ..
}
From another answer:
A little history
Remember, there is nothing inherently special about $
. It is a variable name just like any other. In earlier days, people used to write code using document.getElementById. Because JavaScript is case-sensitive, it was normal to make a mistake while writing document.getElementById
. Should I capital 'b'
of 'by'
? Should I capital 'i'
of Id?
You get the drift. Because functions are first-class citizens in JavaScript, you can always do this:
var $ = document.getElementById; //freedom from document.getElementById!
When Prototype library arrived, they named their function, which gets the DOM elements, as '$'
. Almost all the JavaScript libraries copied this idea. Prototype also introduced a $$
function to select elements using CSS selector.
jQuery also adapted $
function but expanded to make it accept all kinds of 'selectors' to get the elements you want. Now, if you are already using Prototype in your project and wanted to include jQuery, you will be in problem as '$'
could either refer to Prototype's implementation OR jQuery's implementation. That's why jQuery has the option of noConflict so that you can include jQuery in your project which uses Prototype and slowly migrate your code. I think this was a brilliant move on John's part! :)
Double period (..) means you go up one folder and then look for the folder behind the slash. For example:
If your index.html is in the folder html/files
and the fonts are in html/fonts
, the .. is fine (because you have to go back one folder to go to /fonts
). Is your index.html in html
and your fonts in html/fonts
, then you should use only one period.
Another problem could be that your browser might not support .eot font-files.
Without seeing more of your code (and maybe a link to a live version of your website), I can't really help you further.
Edit: Forget the .eot part, I missed the .ttf file in your css.
Try the following:
@font-face {
font-family: Gotham;
src: url(../fonts/gothammedium.eot);
src: url(../fonts/Gotham-Medium.ttf);
}
I did it by other way.
Properties prop = new Properties();
try {
File jarPath=new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());
String propertiesPath=jarPath.getParentFile().getAbsolutePath();
System.out.println(" propertiesPath-"+propertiesPath);
prop.load(new FileInputStream(propertiesPath+"/importer.properties"));
} catch (IOException e1) {
e1.printStackTrace();
}
You haven't specified how would you like to see these details.
For the first sight I would suggest to check Server Management Studio.
You can see the jobs and current statuses in the SQL Server Agent part, under Jobs. If you pick a job, the Property page shows a link to the Job History, where you can see the start and end time, if there any errors, which step caused the error, and so on.
You can specify alerts and notifications to email you or to page you when the job finished successfully or failed.
There is a Job Activity Monitor, but actually I never used it. You can have a try.
If you want to check it via T-SQL, then I don't know how you can do that.
give a try to this class:
class PrimitiveWrapper<T> extends AbstractList<T> {
private final T[] data;
private PrimitiveWrapper(T[] data) {
this.data = data; // you can clone this array for preventing aliasing
}
public static <T> List<T> ofIntegers(int... data) {
return new PrimitiveWrapper(toBoxedArray(Integer.class, data));
}
public static <T> List<T> ofCharacters(char... data) {
return new PrimitiveWrapper(toBoxedArray(Character.class, data));
}
public static <T> List<T> ofDoubles(double... data) {
return new PrimitiveWrapper(toBoxedArray(Double.class, data));
}
// ditto for byte, float, boolean, long
private static <T> T[] toBoxedArray(Class<T> boxClass, Object components) {
final int length = Array.getLength(components);
Object res = Array.newInstance(boxClass, length);
for (int i = 0; i < length; i++) {
Array.set(res, i, Array.get(components, i));
}
return (T[]) res;
}
@Override
public T get(int index) {
return data[index];
}
@Override
public int size() {
return data.length;
}
}
testcase:
List<Integer> ints = PrimitiveWrapper.ofIntegers(10, 20);
List<Double> doubles = PrimitiveWrapper.ofDoubles(10, 20);
// etc
I know it's malapropos, but IMHO easy way is:
def insert (source_str, insert_str, pos):
return source_str[:pos]+insert_str+source_str[pos:]
Try this:
$("div[class]").filter(function() {
var classNames = this.className.split(/\s+/);
for (var i=0; i<classNames.length; ++i) {
if (classNames[i].substr(0, 6) === "apple-") {
return true;
}
}
return false;
})
You can also upload using HTML5. You can use this AJAX uploader.
The JS code is basically:
$scope.doPhotoUpload = function () {
// ..
var myUploader = new uploader(document.getElementById('file_upload_element_id'), options);
myUploader.send();
// ..
}
Which reads from an HTML input element
<input id="file_upload_element_id" type="file" onchange="angular.element(this).scope().doPhotoUpload()">
ng-click "$watch(edit($index), open())"
sys.exit() will do exactly what you want.
import sys
sys.exit("Error message")
With Comodo PositiveSSL we have received 4 files.
When we followed the instructions on comodo site - we would get an error that our certificate was missing an intermediate certificate file.
Basically the syntax is
cat our_domain.crt COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt > domain-ssl_bundle.crt
i solved this in a shorter fashion.
Dim marray() as variant, array2() as variant, YY ,ZZ as integer
YY=1
ZZ=1
Redim marray(1 to 1000, 1 to 10)
Do while ZZ<100 ' this is populating the first array
marray(ZZ,YY)= "something"
ZZ=ZZ+1
YY=YY+1
Loop
'this part is where you store your array in another then resize and restore to original
array2= marray
Redim marray(1 to ZZ-1, 1 to YY)
marray = array2
There are three ways to switch to the frame
1)Can use id
2)Can use name of the frame
3)Can use WebElement of the frame
2->driver.switchTo().frame("name of the frame");
You can use the following command to clear out ALL variables. Be careful because it you cannot get your variables back.
rm(list=ls(all=TRUE))
Same, but different, but still same (can be "tested" multiple times):
const a = { valueOf: () => this.n = (this.n || 0) % 3 + 1}_x000D_
_x000D_
if(a == 1 && a == 2 && a == 3) {_x000D_
console.log('Hello World!');_x000D_
}_x000D_
_x000D_
if(a == 1 && a == 2 && a == 3) {_x000D_
console.log('Hello World!');_x000D_
}
_x000D_
My idea started from how Number object type equation works.
Using \n
in sed
is non-portable. The portable way to do what you want with sed
is:
sed 's/:/\
/g' ~/Desktop/myfile.txt
but in reality this isn't a job for sed
anyway, it's the job tr
was created to do:
tr ':' '
' < ~/Desktop/myfile.txt
When you define any variable then you do not have to put in any extra spaces.
E.g.
name = "Stack Overflow"
// it is not valid, you will get an error saying- "Command not found"
So remove spaces:
name="Stack Overflow"
and it will work fine.
Actually there is a way you can use a background color with a background image. In this case, the background part will be filled with that specified color instead of a white/transparent one.
In order to achieve that, you need to set the background
property like this:
.bg-image-with-color {
background: url("example.png") no-repeat, #ff0000;
}
Note the comma and the color code after no-repeat
; this sets the background color you wish.
I discovered this in this YouTube video, however I'm not affiliated with that channel or video in any means.
If you have multiple ul and want to empty specific ul then use id eg:
<ul id="randomName">
<li>1</li>
<li>2</li>
<li>3</li>
</ul>
<script>
$('#randomName').empty();
</script>
$('input').click(function() {_x000D_
$('#randomName').empty()_x000D_
})
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<ul id="randomName">_x000D_
<li>1</li>_x000D_
<li>2</li>_x000D_
<li>3</li>_x000D_
</ul>_x000D_

<li>5</li>_x000D_

-u no
doesn't show unstaged files either. -uno
works as desired and shows unstaged, but hides untracked.
Use the echo
command:
var="text to append";
destdir=/some/directory/path/filename
if [ -f "$destdir" ]
then
echo "$var" > "$destdir"
fi
The if
tests that $destdir
represents a file.
The >
appends the text after truncating the file. If you only want to append the text in $var
to the file existing contents, then use >>
instead:
echo "$var" >> "$destdir"
The cp
command is used for copying files (to files), not for writing text to a file.
It depends. If the exact answer really matters, do some profiling and find out. If you're sure you'll never have more than a certain number of elements in the set, go with a List. If the number is unbounded, use a HashSet.
Although this is the accepted answer, toto_tico's answer below is better :)
Try making the onclick js use 'return' to ensure the desired return value gets used...
<button type="button" value="click me" onclick="return check_me();" />
I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.
Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled
Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is
Here is the xmlns reference:
xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI"
Then the ad itself:
<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480" AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>
You can store the old innerHTML of the div in a variable. Set an interval to check if the old content matches the current content. When this isn't true do something.
I just wrote this function, it should do the trick for you, but it does left join
public function mergePerKey($array1,$array2)
{
$mergedArray = [];
foreach ($array1 as $key => $value)
{
if(isset($array2[$key]))
{
$mergedArray[$value] = null;
continue;
}
$mergedArray[$value] = $array2[$key];
}
return $mergedArray;
}
sometimes above queries will not give correct result, there is built in stored procedure available to get the table dependencies as:
EXEC sp_depends @objname = N'TableName';
function deleteEmpty(obj){
for(var k in obj)
if(k == "children"){
if(obj[k]){
deleteEmpty(obj[k]);
}else{
delete obj.children;
}
}
}
for(var i=0; i< a.children.length; i++){
deleteEmpty(a.children[i])
}
MyList.OrderBy(x => x.StartDate).ThenByDescending(x => x.EndDate);
Note that you can use as well the Descending keyword in the OrderBy (in case you need). So another possible answer is:
MyList.OrderByDescending(x => x.StartDate).ThenByDescending(x => x.EndDate);
You could define your own extension method, but I wouldn't recommend that.
public static IEnumerable<TResult> SelectNonNull<T, TResult>(this IEnumerable<T> sequence,Func<T, TResult> projection)
{
return sequence.Select(projection).Where(e => e != null);
}
I don't like this one because it mixes two concerns. Projecting with Select
and filtering your null values are separate operations and should not be combined into one method.
I'd rather define an extension method that only checks if the item isn't null:
public static IEnumerable<T> WhereNotNull<T>(this IEnumerable<T> sequence)
{
return sequence.Where(e => e != null);
}
public static IEnumerable<T> WhereNotNull<T>(this IEnumerable<T?> sequence)
where T : struct
{
return sequence.Where(e => e != null).Select(e => e.Value);
}
This has only a single purpose, checking for null. For nullable value types it converts to the non nullable equivalent, since it's useless to preserve the nullable wrapper for values which cannot be null.
With this method, your code becomes:
list.Select(item => item.MyProperty).WhereNotNull()
For me WORKSPACE was a valid property of the pipeline itself. So when I handed over this
to a Groovy method as parameter context
from the pipeline script itself, I was able to access the correct value using "... ${context.WORKSPACE} ..."
(on Jenkins 2.222.3, Build Pipeline Plugin 1.5.8, Pipeline: Nodes and Processes 2.35)
Sometimes the problem may be if you import
that like this:
const Vue = window.vue;
this may overwrite the original Vue
reference.
This worked for me
let routes = []
app._router.stack.forEach(function (middleware) {
if(middleware.route) {
routes.push(Object.keys(middleware.route.methods) + " -> " + middleware.route.path);
}
});
console.log(JSON.stringify(routes, null, 4));
O/P:
[
"get -> /posts/:id",
"post -> /posts",
"patch -> /posts"
]
You can either use:
return X. this will return only one value.
return object. will return a full object. For example your object might include X, Y, and Z values.
pass array. arrays are passed by reference. i.e. if you pass array of integers, modified the array inside the method, then the original code will see the changes.
Example on passing Array.
void methodOne{
int [] arr = {1,2,3};
methodTwo(arr);
...//print arr here
}
void methodTwo(int [] arr){
for (int i=0; i<arr.length;i++){
arr[i]+=3;
}
}
This will print out: 4,5,6.
One of the possible way to do it:
import urllib
...
try:
# Python 2
from urllib2 import urlopen
except ImportError:
# Python 3
from urllib.request import urlopen
I suggest you replace the deprecated apache HttpClient with the new HttpURLConnection.
That's a cleaner solution, it's quite easy to migrate, and generally it's better to stick to the latest SDK changes than trying to hack/patch/workaround: you usually regret it later :)
Step 1
HttpGet httpGet = new HttpGet(url);
becomes:
URL urlObj = new URL(url);
Step 2
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpResponse response = httpClient.execute(httpGet, localContext);
InputStream is = response.getEntity().getContent();
becomes:
HttpURLConnection urlConnection = (HttpURLConnection) urlObj.openConnection();
InputStream is = urlConnection.getInputStream();
Step 2 bis
int status = response.getStatusLine().getStatusCode();
becomes:
int status = urlConnection.getResponseCode();
It works for me:
if (isset($_POST['MyTextAreaName'])){
$array=explode( "\r\n", $_POST['MyTextAreaName'] );
now, my $array will have all the lines I need
for ($i = 0; $i <= count($array); $i++)
{
echo (trim($array[$i]) . "<br/>");
}
(make sure to close the if
block with another curly brace)
}
Let's say we have an async function
async def work_async(self, student_name: str, code: str, loop):
"""
Some async function
"""
# Do some async procesing
That needs to be run on a large array. Some attributes are being passed to the program and some are used from property of dictionary element in the array.
async def process_students(self, student_name: str, loop):
market = sys.argv[2]
subjects = [...] #Some large array
batchsize = 5
for i in range(0, len(subjects), batchsize):
batch = subjects[i:i+batchsize]
await asyncio.gather(*(self.work_async(student_name,
sub['Code'],
loop)
for sub in batch))
I see lots of good examples listed on here, wanted to throw mine in as well.
#! /bin/bash
items="1 2 3 4 5 6"
pids=""
for item in $items; do
sleep $item &
pids+="$! "
done
for pid in $pids; do
wait $pid
if [ $? -eq 0 ]; then
echo "SUCCESS - Job $pid exited with a status of $?"
else
echo "FAILED - Job $pid exited with a status of $?"
fi
done
I use something very similar to start/stop servers/services in parallel and check each exit status. Works great for me. Hope this helps someone out!
I found a quick way for this:
log = open("log.txt", 'a')
def oprint(message):
print(message)
global log
log.write(message)
return()
code ...
log.close()
Whenever you want to print something just use oprint rather than print.
Note1: In case you want to put the function oprint in a module then import it, use:
import builtins
builtins.log = open("log.txt", 'a')
Note2: what you pass to oprint should be a one string (so if you were using a comma in your print to separate multiple strings, you may replace it with +)
Since I think you are new with Python, lets do the long way, iterate thru your list using for loop and multiply and append each element to a new list.
using for loop
lst = [5, 20 ,15]
product = []
for i in lst:
product.append(i*5)
print product
using list comprehension, this is also same as using for-loop but more 'pythonic'
lst = [5, 20 ,15]
prod = [i * 5 for i in lst]
print prod
Importing a whole library seems inefficient when all you need is essentially two lines of code...
$ldap = ldap_connect("ldap.example.com");
if ($bind = ldap_bind($ldap, $_POST['username'], $_POST['password'])) {
// log them in!
} else {
// error message
}
def jsonFile = new File('File Path');
JsonSlurper jsonSlurper = new JsonSlurper();
def parseJson = jsonSlurper.parse(jsonFile)
String json = JsonOutput.toJson(parseJson)
def prettyJson = JsonOutput.prettyPrint(json)
println(prettyJson)
The best solution I have found is this:
function subtracMonth($currentMonth, $monthsToSubtract){
$finalMonth = $currentMonth;
for($i=0;$i<$monthsToSubtract;$i++) {
$finalMonth--;
if ($finalMonth=='0'){
$finalMonth = '12';
}
}
return $finalMonth;
}
So if we are in 3(March) and we want to subtract 5 months that would be
subtractMonth(3,5);
which would give 10(October). If the year is also desired, one could do this:
function subtracMonth($currentMonth, $monthsToSubtract){
$finalMonth = $currentMonth;
$totalYearsToSubtract = 0;
for($i=0;$i<$monthsToSubtract;$i++) {
$finalMonth--;
if ($finalMonth=='0'){
$finalMonth = '12';
$totalYearsToSubtract++;
}
}
//Get $currentYear
//Calculate $finalYear = $currentYear - $totalYearsToSubtract
//Put resulting $finalMonth and $finalYear into an object as attributes
//Return the object
}
For Spring 4 I use the following
(I am posting it as the question is 4 years old and more people use Spring 4 than Spring 3.1):
@Configuration
@ComponentScan(basePackages = "com.example",
excludeFilters = @Filter(type=FilterType.REGEX,pattern="com\\.example\\.ignore\\..*"))
public class RootConfig {
// ...
}
If multiple characters are bound inside a single integer/long, as was my issue:
s = '0123456789'
nchars = len(s)
# string to int or long. Type depends on nchars
x = sum(ord(s[byte])<<8*(nchars-byte-1) for byte in range(nchars))
# int or long to string
''.join(chr((x>>8*(nchars-byte-1))&0xFF) for byte in range(nchars))
Yields '0123456789'
and x = 227581098929683594426425L
Tested in IE, Firefox, and Chrome.

If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:
Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);
Hope it helps.
first run below commands as super user
sudo code . --user-data-dir='.'
it will open the visual code studio import the folder of your project and set the launch.json as below
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Launch Program",
"program": "${workspaceFolder}/app/release/web.js",
"outFiles": [

}
path of runtimeExecutable will be output of "which node"
command.
Run the server in debug mode cheers
It is possible to do (in the deployed repository)
git fetch
git checkout origin/master -- path/to/file
The fetch will download all the recent changes, but it will not put it in your current checked out code (working area).
The checkout will update the working tree with the particular file from the downloaded changes (origin/master
).
At least this works for me for those little small typo fixes, where it feels weird to create a branch etc just to change one word in a file.
In View:
<Button
Height="50" Width="50"
Style="{StaticResource MyButtonStyle}"
Command="{Binding SmallDisp}" CommandParameter="{Binding}"
Cursor="Hand" Visibility="{Binding Path=AdvancedFormat}"/>
In view Model:
public _advancedFormat = Visibility.visible (whatever you start with)
public Visibility AdvancedFormat
{
get{return _advancedFormat;}
set{
_advancedFormat = value;
//raise property changed here
}
You will need to have a property changed event
protected virtual void OnPropertyChanged(PropertyChangedEventArgs e)
{
PropertyChanged.Raise(this, e);
}
protected void OnPropertyChanged(string propertyName)
{
OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
}
This is how they use Model-view-viewmodel
But since you want it binded to a boolean, You will need some converter. Another way is to set a boolean outside and when that button is clicked then set the property_advancedFormat to your desired visibility.
The question was:
I would like to handle errors from Guzzle when the server returns 4xx and 5xx status codes
The other answers are mostly incomplete. 404 and 500 will throw different exceptions.
Also, the question is do you just want to handle the errors or do you want to get the body? I think in most cases it would be sufficient to handle the errors and not get the message body.
I would look at the documentation to check how your version of Guzzle handles it because this may change: https://docs.guzzlephp.org/en/stable/quickstart.html#exceptions
Guzzle 7 (from the docs):
. \RuntimeException
+-- TransferException (implements GuzzleException)
+-- RequestException
+-- BadResponseException
¦ +-- ServerException
¦ +-- ClientException
+-- ConnectException
+-- TooManyRedirectsException
So, you code might look like this:
try {
$response = $client->request('GET', $url);
if ($response->getStatusCode() >= 300) {
$statusCode = $response->getStatusCode();
// handle error
} else {
// is valid URL
}
} catch (TooManyRedirectsException $e) {
// handle too many redirects
} catch (ClientException | ServerException $e) {
// ClientException - A GuzzleHttp\Exception\ClientException is thrown for 400 level errors if the http_errors request option is set to true.
// ServerException - A GuzzleHttp\Exception\ServerException is thrown for 500 level errors if the http_errors request option is set to true.
if ($e->hasResponse()) {
$statusCode = $e->getResponse()->getStatusCode();
}
} catch (ConnectException $e) {
// ConnectException - A GuzzleHttp\Exception\ConnectException exception is thrown in the event of a networking error. This may be any libcurl error, including certificate problems
$handlerContext = $e->getHandlerContext();
if ($handlerContext['errno'] ?? 0) {
// this is the libcurl error code, not the HTTP status code!!!
$errno = (int)($handlerContext['errno']);
}
} catch (\Exception $e) {
// fallback, in case of other exception
}
If you really need the body, you can retrieve it as usual:
https://docs.guzzlephp.org/en/stable/quickstart.html#using-responses
$body = $response->getBody();
On Ubuntu:
sudo apt-get install python-virtualenv
The package python-pip
is a dependency, so it will be installed as well.
Thanks, all, for the help. Picking from here and there comes this solution. This compiles clean. Have not tested the code yet. Tomorrow... maybe...
const char * timeServer[] = { "pool.ntp.org" }; // 0 - Worldwide
#define WHICH_NTP 0 // Which NTP server name to use.
...
sendNTPpacket(const_cast<char*>(timeServer[WHICH_NTP])); // send an NTP packet to a server
...
void sendNTPpacket(char* address) { code }
I know, there's only 1 item in the timeServer array. But there could be more. The rest were commented out for now to save memory.
You are assigning to a function call:
invest(initial_amount,top_company(5,year,year+1)) = subsequent_amount
which is illegal in Python. The question is, what do you want to do? What does invest()
do? I suppose it returns a value, namely what you're trying to use as subsequent_amount
, right?
If so, then something like this should work:

For a start, your answer
variable should be of type char
, not char*
.
As for the if
statement:
if (answer == ('Y' || 'y'))
This is first evaluating 'Y' || 'y'
which, in Boolean logic (and for ASCII) is true since both of them are "true" (non-zero). In other words, you'd only get the if
statement to fire if you'd somehow entered CTRLA (again, for ASCII, and where a true values equates to 1)*a.
You could use the more correct:
if ((answer == 'Y') || (answer == 'y'))
but you really should be using:
if (toupper(answer) == 'Y')
since that's the more portable way to achieve the same end.
*a You may be wondering why I'm putting in all sorts of conditionals for my statements. While the vast majority of C implementations use ASCII and certain known values, it's not necessarily mandated by the ISO standards. I know for a fact that at least one compiler still uses EBCDIC so I don't like making unwarranted assumptions.
They're logically identical, but in the earlier versions of Oracle that adopted ANSI syntax there were often bugs with it in more complex cases, so you'll sometimes encounter resistance from Oracle developers when using it.
Date for the future 1 year can be done by
$('.date').datepicker({dateFormat: 'yy-mm-dd', minDate:(0), maxDate:(365)});
you can change the date format too by the parameter dateFormat
Not necessarily the most compact way of doing this, but quite clean IMO
if(json == null) {
throw new BadThingException();
}
...
@ExceptionHandler(BadThingException.class)
@ResponseStatus(value = HttpStatus.BAD_REQUEST)
public @ResponseBody MyError handleException(BadThingException e) {
return new MyError("That doesnt work");
}
Edit you can use @ResponseBody in the exception handler method if using Spring 3.1+, otherwise use a ModelAndView
or something.
Fake IE10 to install Visual Studio 2013
Visual Studio 2013 requires Internet Explorer 10. If you try to install it on Windows 7 with IE8 you get the following error This version of Visual Studio requires Internet Explorer 10”. The value that the VS 2013 installer checks is svcVersion in the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer
key on 32-bit Windows andHKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer
on 64-bit Windows. Any value >= 10.0.0.0 makes the installer happy.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer]
"svcVersion"="10.0.0.0"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer]
"svcVersion"="10.0.0.0"
As the error information said first please try to increase the timeout value in the both the client side and service side as following:
<basicHttpBinding>
<binding name="basicHttpBinding_ACRMS" maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647"
openTimeout="00:20:00"
receiveTimeout="00:20:00" closeTimeout="00:20:00"
sendTimeout="00:20:00">
<readerQuotas maxDepth="32" maxStringContentLength="2097152"
maxArrayLength="2097152" maxBytesPerRead="4006" maxNameTableCharCount="16384" />
</binding>
Then please do not forget to apply this binding configuration to the endpoint by doing the following:
<endpoint address="" binding="basicHttpBinding"
bindingConfiguration="basicHttpBinding_ACRMS"
contract="MonitorRAM.IService1" />
If the above can not help, it will be better if you can try to upload your main project here, then I want to have a test in my side.
you can add values to specific columns as well, just specify the column names in which you like to add corresponding values:
Insert into Table (Col1, Col2, Col4,col5,Col7) Values ('Va11','Va2','Val4','Val5','Val7');
Make sure the columns you skip dont have not null value type.
exec
is often used in conjunction with fork
, which I saw that you also asked about, so I will discuss this with that in mind.
exec
turns the current process into another program. If you ever watched Doctor Who, then this is like when he regenerates -- his old body is replaced with a new body.
The way that this happens with your program and exec
is that a lot of the resources that the OS kernel checks to see if the file you are passing to exec
as the program argument (first argument) is executable by the current user (user id of the process making the exec
call) and if so it replaces the virtual memory mapping of the current process with a virtual memory the new process and copies the argv
and envp
data that were passed in the exec
call into an area of this new virtual memory map. Several other things may also happen here, but the files that were open for the program that called exec
will still be open for the new program and they will share the same process ID, but the program that called exec
will cease (unless exec failed).
The reason that this is done this way is that by separating running a new program into two steps like this you can do some things between the two steps. The most common thing to do is to make sure that the new program has certain files opened as certain file descriptors. (remember here that file descriptors are not the same as FILE *
, but are int
values that the kernel knows about). Doing this you can:
int X = open("./output_file.txt", O_WRONLY);
pid_t fk = fork();
if (!fk) { /* in child */
dup2(X, 1); /* fd 1 is standard output,
so this makes standard out refer to the same file as X */
close(X);
/* I'm using execl here rather than exec because
it's easier to type the arguments. */
execl("/bin/echo", "/bin/echo", "hello world");
_exit(127); /* should not get here */
} else if (fk == -1) {
/* An error happened and you should do something about it. */
perror("fork"); /* print an error message */
}
close(X); /* The parent doesn't need this anymore */
This accomplishes running:
/bin/echo "hello world" > ./output_file.txt
from the command shell.
If I'm starting a long-running process like a copy or hash and I want to know later how long it took, I just do this:
$ date; sha1sum reallybigfile.txt; date
Which will result in the following output:
Tue Jun 2 21:16:03 PDT 2015
5089a8e475cc41b2672982f690e5221469390bc0 reallybigfile.txt

Granted, as implemented here it isn't very precise and doesn't calculate the elapsed time. But it's dirt simple and sometimes all you need.
There are many realizations of hash functions written in JS. For example:
If you don't need security, you can also use base64 which is not hash-function, has not fixed output and could be simply decoded by user, but looks more lightweight and could be used for hide values: http://www.webtoolkit.info/javascript-base64.html
I guess the second declaration is confusing to many. Here's an easy way to understand it.
Lets have an array of integers, i.e. int B[8]
.
Let's also have a variable A which points to B. Now, value at A is B, i.e. (*A) == B
. Hence A points to an array of integers. In your question, arr is similar to A.
Similarly, in int* (*C) [8]
, C is a pointer to an array of pointers to integer.
Another minimalist Python solution without using numpy:
[0 if i < 0 else i for i in a]
No need to define any extra functions.
a = [1, 2, 3, -4, -5.23, 6]
[0 if i < 0 else i for i in a]
yields:
[1, 2, 3, 0, 0, 6]
You need to use overflow option like below:
.nav{
max-height: 300px;
overflow-y: scroll;
}
Change the height according to amount of items you need to show
Actually as answered before starting with API Level 18 you can cancel Notifications posted by other apps differet than your own using NotificationListenerService but that approach will no longer work on Lollipop, here is the way to remove notifications covering also Lillipop API.
if (Build.VERSION.SDK_INT < 21) {
cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId());
}
else {
cancelNotification(sbn.getKey());
}
Perhaps a more logical method would be to create a file (e.g. test.html), add some content and then try to set it as the index page:
DirectoryIndex test.html
For the most part, the .htaccess rule will override the Apache configuration where working at the directory/file level
Here's my pure pathlib
recursive directory unlinker:
from pathlib import Path
def rmdir(directory):
directory = Path(directory)
for item in directory.iterdir():
if item.is_dir():
rmdir(item)
else:
item.unlink()
directory.rmdir()
rmdir(Path("dir/"))
If you have access to a console in the context you are investigating, you can determine which version you are running by printing the value of the global constant RUBY_VERSION
.

you have to create an entry inside res/menu,
override onCreateOptionsMenu
and inflate it
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.yourentry, menu);
return true;
}
an entry for the menu could be:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/action_cart"
android:icon="@drawable/cart"
android:orderInCategory="100"

You need to use the starts with selector
var elems = $( "[name^='pages_title']" );
But a better solution is to add a class to the elements and reference the class. The reason it is a faster look up.
Surfing the web, you will find many technical justifications for Quadro price. Real answer is in "demand for reliable and task specific graphic cards".
Imagine you have an architectural firm with many fat projects on deadline. Your computers are only used in working with one specific CAD software. If foundation of your business is supposed to rely on these computers, you would want to make sure this foundation is strong.
For such clients, Nvidia engineered cards like Quadro, providing what they call "Professional Solution". And if you are among the targeted clients, you would really appreciate reliability of these graphic cards.
Many believe Geforce have become powerful and reliable enough to take Quadro's place. But in the end, it depends on the software you are mostly going to use and importance of reliability in what you do.
Can someone point me to a book or website which explains these basics clearly ?
You can check this XML Tutorial with examples.
But what about the encoding part ? Why is that necessary ?
W3C provides explanation about encoding :
"The document character set for XML and HTML 4.0 is Unicode (aka ISO 10646). This means that HTML browsers and XML processors should behave as if they used Unicode internally. But it doesn't mean that documents have to be transmitted in Unicode. As long as client and server agree on the encoding, they can use any encoding that can be converted to Unicode..."
All tables within the bootstrap stretch according to their container, which you can easily do by placing your table inside a .span*
grid element of your choice. If you wish to remove this property you can create your own table class and simply add it to the table you want to expand with the content within:
.table-nonfluid {
width: auto !important;
}
You can add this class inside your own stylesheet and simply add it to the container of your table like so:
<table class="table table-nonfluid"> ... </table>
This way your change won't affect the bootstrap stylesheet itself (you might want to have a fluid table somewhere else in your document).
You have to set the timezone, cf http://www.php.net/manual/en/book.datetime.php
Use .length
refer to http://api.jquery.com/checked-selector/
if ($('input[name="html_elements"]:checked').length === 0) alert("Not checked");
else alert("Checked");
Personally, I tend to use awk for jobs like this. For example:
ps axu| grep jboss | grep -v grep | awk '{print $5}'
I have found a great and easy way for this.
In the console - right click on the console logged object
Click on 'Store as global variable'
See the name of the new variable - e.g. it is variableName1
Type in the console: JSON.stringify(variableName1)
Copy the variable string content: e.g. {"a":1,"b":2,"c":3}
You can get to SIZES
by means of self.SIZES
(in an instance method) or cls.SIZES
(in a class method).
In any case, you will have to be explicit about where to find SIZES
. An alternative is to put SIZES
in the module containing the classes, but then you need to define all classes in a single module.
302 is temporary redirect, which is generated by the server whereas 307 is internal redirect response generated by the browser. Internal redirect means that redirect is done automatically by browser internally, basically the browser alters the entered url from http to https in get request by itself before making the request so request for unsecured connection is never made to the internet. Whether browser will alter the url to https or not depends upon the hsts preload list that comes preinstalled with the browser. You can also add any site which support https to the list by entering the domain in the hsts preload list of your own browser which is at chrome://net-internals/#hsts.One more thing website domains can be added by their owners to preload list by filling up the form at https://hstspreload.org/ so that it comes preinstalled in browsers for every user even though I mention you can do particularly for yourself also.
Let me explain with an example:
I made a get request to http://www.pentesteracademy.com which supports only https and I don't have that domain in my hsts preload list on my browser as site owner has not registered for it to come with preinstalled hsts preload list.
GET request for unsecure version of the site is redirected to secure version(see http header named location for that in response in above image).
Now I add the site to my own browser preload list by adding its domain in Add hsts domain form at chrome://net-internals/#hsts, which modifies my personal preload list on my chrome browser.Be sure to select include subdomains for STS option there.
Let's see the request and response for the same website now after adding it to hsts preload list.
you can see the internal redirect 307 there in response headers, actually this response is generated by your browser not by server.
Also HSTS preload list can help prevent users reach the unsecure version of site as 302 redirect are prone to mitm attacks.
Hope I somewhat helped you understand more about redirects.
I use this - it never fails:
startingpoint = 'blah'
if sys.argv[1:]:
startingpoint = sys.argv[1]
Yes, you need a loop. If you already have a main loop (most GUI event-driven stuff does) you can probably stick your timer into that. Use:
#include <time.h>
time_t my_t, fire_t;
Then (for times over 1 second), initialize your timer by reading the current time:
my_t = time(NULL);
Add the number of seconds your timer should wait and store it in fire_t. A time_t is essentially a uint32_t, you may need to cast it.
Inside your loop do another
my_t = time(NULL);
if (my_t > fire_t) then consider the timer fired and do the stuff you want there. That will probably include resetting it by doing another fire_t = time(NULL) + seconds_to_wait for next time.
A time_t is a somewhat antiquated unix method of storing time as the number of seconds since midnight 1/1/1970 but it has many advantages. For times less than 1 second you need to use gettimeofday() (microseconds) or clock_gettime() (nanoseconds) and deal with a struct timeval or struct timespec which is a time_t and the microseconds or nanoseconds since that 1 second mark. Making a timer works the same way except when you add your time to wait you need to remember to manually do the carry (into the time_t) if the resulting microseconds or nanoseconds value goes over 1 second. Yes, it's messy. See man 2 time, man gettimeofday, man clock_gettime.
sleep(), usleep(), nanosleep() have a hidden benefit. You see it as pausing your program, but what they really do is release the CPU for that amount of time. Repeatedly polling by reading the time and comparing to the done time (are we there yet?) will burn a lot of CPU cycles which may slow down other programs running on the same machine (and use more electricity/battery). It's better to sleep() most of the time then start checking the time.
If you're trying to sleep and do work at the same time you need threads.
Bootstrap people use .hidden

I had the same need and found this answer ..
This creates a record in the company table (comp), it the grabs the auto ID created on the company table and drops that into a Staff table (staff) so the 2 tables can be linked, MANY staff to ONE company. It works on my SQL 2008 DB, should work on SQL 2005 and above.
===========================
CREATE PROCEDURE [dbo].[InsertNewCompanyAndStaffDetails]
@comp_name varchar(55) = 'Big Company',
@comp_regno nchar(8) = '12345678',
@comp_email nvarchar(50) = '[email protected]',
@recID INT OUTPUT
-- The '@recID' is used to hold the Company auto generated ID number that we are about to grab
AS
Begin
SET NOCOUNT ON
DECLARE @tableVar TABLE (tempID INT)
-- The line above is used to create a tempory table to hold the auto generated ID number for later use. It has only one field 'tempID' and its type INT is the same as the '@recID'.
INSERT INTO comp(comp_name, comp_regno, comp_email)
OUTPUT inserted.comp_id INTO @tableVar
-- The 'OUTPUT inserted.' line above is used to grab data out of any field in the record it is creating right now. This data we want is the ID autonumber. So make sure it says the correct field name for your table, mine is 'comp_id'. This is then dropped into the tempory table we created earlier.
VALUES (@comp_name, @comp_regno, @comp_email)
SET @recID = (SELECT tempID FROM @tableVar)
-- The line above is used to search the tempory table we created earlier where the ID we need is saved. Since there is only one record in this tempory table, and only one field, it will only select the ID number you need and drop it into '@recID'. '@recID' now has the ID number you want and you can use it how you want like i have used it below.
INSERT INTO staff(Staff_comp_id)
VALUES (@recID)
End
-- So there you go. You can actually grab what ever you want in the 'OUTPUT inserted.WhatEverFieldNameYouWant' line and create what fields you want in your tempory table and access it to use how ever you want.

Another possibility when using easy_install is that you need to require the most recent version of matplotlib. Try:
import pkg_resources
pkg_resources.require("matplotlib")
before you import matplotlib or any of its modules.
