The simplest solution I've found that doesn't require a plugin:
document.addEventListener('touchstart', handleTouchStart, false);
document.addEventListener('touchmove', handleTouchMove, false);
var xDown = null;
var yDown = null;
function handleTouchStart(evt) {
xDown = evt.touches[0].clientX;
yDown = evt.touches[0].clientY;
};
function handleTouchMove(evt) {
if ( ! xDown || ! yDown ) {
return;
}
var xUp = evt.touches[0].clientX;
var yUp = evt.touches[0].clientY;
var xDiff = xDown - xUp;
var yDiff = yDown - yUp;
if ( Math.abs( xDiff ) > Math.abs( yDiff ) ) {/*most significant*/
if ( xDiff > 0 ) {
/* left swipe */
} else {
/* right swipe */
}
} else {
if ( yDiff > 0 ) {
/* up swipe */
} else {
/* down swipe */
}
}
/* reset values */
xDown = null;
yDown = null;
};
To get the script, that currently loaded the script you can use
var thisScript = document.currentScript;
You need to keep a reference at the beginning of your script, so you can call later
var url = thisScript.src
You can also use a regular expression to explicitly detect uppercase roman alphabetical characters.
isUpperCase = function(char) {
return !!/[A-Z]/.exec(char[0]);
};
EDIT: the above function is correct for ASCII/Basic Latin Unicode, which is probably all you'll ever care about. The following version also support Latin-1 Supplement and Greek and Coptic Unicode blocks... In case you needed that for some reason.
isUpperCase = function(char) {
return !!/[A-ZÀ-ÖØ-Þ??-??-?????????????-?]/.exec(char[0]);
};
This strategy starts to fall down if you need further support (is ? uppercase?) since some blocks intermix upper and lowercase characters.
In the case of winforms:
If you include the images to your resources you can do it like this, very simple and straight forward:
public Form1()
{
InitializeComponent();
button1.MouseEnter += new EventHandler(button1_MouseEnter);
button1.MouseLeave += new EventHandler(button1_MouseLeave);
}
void button1_MouseLeave(object sender, EventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img1));
}
void button1_MouseEnter(object sender, EventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}
I would not recommend hardcoding image paths.
As you have altered your question ...
There is no (on)MouseOver in winforms afaik, there are MouseHover and MouseMove events, but if you change image on those, it will not change back, so the MouseEnter + MouseLeave are what you are looking for I think. Anyway, changing the image on Hover or Move :
in the constructor:
button1.MouseHover += new EventHandler(button1_MouseHover);
button1.MouseMove += new MouseEventHandler(button1_MouseMove);
void button1_MouseMove(object sender, MouseEventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}
void button1_MouseHover(object sender, EventArgs e)
{
this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}
To add images to your resources: Projectproperties/resources/add/existing file
define this "decoratorize function" to generate customized decorator function:
def decoratorize(FUN, **kw):
def foo(*args, **kws):
return FUN(*args, **kws, **kw)
return foo
use it this way:
@decoratorize(FUN, arg1 = , arg2 = , ...)
def bar(...):
...
If startDate and endDate are instance of java.util.Date
We can use the between( ) method from ChronoUnit enum:
public long between(Temporal temporal1Inclusive, Temporal temporal2Exclusive) {
//..
}
ChronoUnit.DAYS count days which completed 24 hours.
import java.time.temporal.ChronoUnit;
ChronoUnit.DAYS.between(startDate.toInstant(), endDate.toInstant());
//OR
ChronoUnit.DAYS.between(Instant.ofEpochMilli(startDate.getTime()), Instant.ofEpochMilli(endDate.getTime()));
Here is code that will upload multiple images at once, into a specific folder!
The HTML:
<form method="post" enctype="multipart/form-data" id="image_upload_form" action="submit_image.php">
<input type="file" name="images" id="images" multiple accept="image/x-png, image/gif, image/jpeg, image/jpg" />
<button type="submit" id="btn">Upload Files!</button>
</form>
<div id="response"></div>
<ul id="image-list">
</ul>
The PHP:
<?php
$errors = $_FILES["images"]["error"];
foreach ($errors as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$name = $_FILES["images"]["name"][$key];
//$ext = pathinfo($name, PATHINFO_EXTENSION);
$name = explode("_", $name);
$imagename='';
foreach($name as $letter){
$imagename .= $letter;
}
move_uploaded_file( $_FILES["images"]["tmp_name"][$key], "images/uploads/" . $imagename);
}
}
echo "<h2>Successfully Uploaded Images</h2>";
And finally, the JavaSCript/Ajax:
(function () {
var input = document.getElementById("images"),
formdata = false;
function showUploadedItem (source) {
var list = document.getElementById("image-list"),
li = document.createElement("li"),
img = document.createElement("img");
img.src = source;
li.appendChild(img);
list.appendChild(li);
}
if (window.FormData) {
formdata = new FormData();
document.getElementById("btn").style.display = "none";
}
input.addEventListener("change", function (evt) {
document.getElementById("response").innerHTML = "Uploading . . ."
var i = 0, len = this.files.length, img, reader, file;
for ( ; i < len; i++ ) {
file = this.files[i];
if (!!file.type.match(/image.*/)) {
if ( window.FileReader ) {
reader = new FileReader();
reader.onloadend = function (e) {
showUploadedItem(e.target.result, file.fileName);
};
reader.readAsDataURL(file);
}
if (formdata) {
formdata.append("images[]", file);
}
}
}
if (formdata) {
$.ajax({
url: "submit_image.php",
type: "POST",
data: formdata,
processData: false,
contentType: false,
success: function (res) {
document.getElementById("response").innerHTML = res;
}
});
}
}, false);
}());
Hope this helps
An improved version of @Thomas K's answer:
is_any_thread_alive()
according to this gist, which can terminates the main()
automatically.Example codes:
import threading
def job1():
...
def job2():
...
def is_any_thread_alive(threads):
return True in [t.is_alive() for t in threads]
if __name__ == "__main__":
...
t1 = threading.Thread(target=job1,daemon=True)
t2 = threading.Thread(target=job2,daemon=True)
t1.start()
t2.start()
while is_any_thread_alive([t1,t2]):
time.sleep(0)
As some mentioned in the comments, you can put the images in the public folder. This is also explained in the docs of Create-React-App: https://create-react-app.dev/docs/using-the-public-folder/
From axios docs you have baseURL and url
baseURL
will be prepended to url
when making requests. So you can define baseURL
as http://127.0.0.1:8000
and make your requests to /url
// `url` is the server URL that will be used for the request url: '/user', // `baseURL` will be prepended to `url` unless `url` is absolute. // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs // to methods of that instance. baseURL: 'https://some-domain.com/api/',
Namespacing. JavaScript's scopes are function-level.

My gut told me the same thing when I came across this design.
I am working on a code base where there are three dbContexts to one database. 2 out of the 3 dbcontexts are dependent on information from 1 dbcontext because it serves up the administrative data. This design has placed constraints on how you can query your data. I ran into this problem where you cannot join across dbcontexts. Instead what you are required to do is query the two separate dbcontexts then do a join in memory or iterate through both to get the combination of the two as a result set. The problem with that is instead of querying for a specific result set you are now loading all your records into memory and then doing a join against the two result sets in memory. It can really slow things down.
I would ask the question "just because you can, should you?"
See this article for the problem I came across related to this design.
The specified LINQ expression contains references to queries that are associated with different contexts
Here's a cool solution I came up to safely specify hosts via the --limit
option. In this example, the play will end if the playbook was executed without any hosts specified via the --limit
option.
This was tested on Ansible version 2.7.10
---
- name: Playbook will fail if hosts not specified via --limit option.
# Hosts must be set via limit.
hosts: "{{ play_hosts }}"
connection: local
gather_facts: false
tasks:
- set_fact:
inventory_hosts: []
- set_fact:
inventory_hosts: "{{inventory_hosts + [item]}}"
with_items: "{{hostvars.keys()|list}}"
- meta: end_play
when: "(play_hosts|length) == (inventory_hosts|length)"
- debug:
msg: "About to execute tasks/roles for {{inventory_hostname}}"
It's treating the string application
as your URL.
This means your shell isn't parsing the command correctly.
My guess is that you copied the string from somewhere, and that when you pasted it, you got some characters that looked like regular quotes, but weren't.
Try retyping the command; you'll only get valid characters from your keyboard. I bet you'll get a much different result from what looks like the same query.
As this is probably a shell problem and not a 'curl' problem (you didn't build cURL yourself from source, did you?), it might be good to mention whether you're on Linux/Windows/etc.
use:
NSLog(@"%f",[[UIScreen mainScreen] bounds].size.width) ;
May this also can help using configuration file like java class way.
@Configuration
@PropertySource("classpath:application.properties")
public class DataSourceConfig {
@Autowired
JdbcConfigProperties jdbc;
@Bean(name = "hikariDataSource")
public DataSource hikariDataSource() {
HikariConfig config = new HikariConfig();
HikariDataSource dataSource;
config.setJdbcUrl(jdbc.getUrl());
config.setUsername(jdbc.getUser());
config.setPassword(jdbc.getPassword());
// optional: Property setting depends on database vendor
config.addDataSourceProperty("cachePrepStmts", "true");
config.addDataSourceProperty("prepStmtCacheSize", "250");
config.addDataSourceProperty("prepStmtCacheSqlLimit", "2048");
dataSource = new HikariDataSource(config);
return dataSource;
}
}
How to use it:
@Component
public class Car implements Runnable {
private static final Logger logger = LoggerFactory.getLogger(AptSommering.class);
@Autowired
@Qualifier("hikariDataSource")
private DataSource hikariDataSource;
}
I had a similar problem with R-studio. When I tried to do my plots, this message was showing up.
Eventually I realised that the reason behind this was that my "window" for the plots was too small, and I had to make it bigger to "fit" all the plots inside!
Hope to help
Below is a fully functional example of what I believe you're trying to do (with a functional snippet).
Based on your question, you seem to be modifying 1 property in state
for all of your elements. That's why when you click on one, all of them are being changed.
In particular, notice that the state tracks an index of which element is active. When MyClickable
is clicked, it tells the Container
its index, Container
updates the state
, and subsequently the isActive
property of the appropriate MyClickable
s.
class Container extends React.Component {_x000D_
state = {_x000D_
activeIndex: null_x000D_
}_x000D_
_x000D_

<MyClickable name="c" index={2} isActive={ this.state.activeIndex===2 } onClick={ this.handleClick }/>_x000D_
</div>_x000D_
}_x000D_
}_x000D_

handleClick = () => this.props.onClick(this.props.index)_x000D_
_x000D_

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable
elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.
// New render method for `Container`
render() {
const clickables = [
{ name: "a" },
{ name: "b" },
{ name: "c" },
]
return <div>
{ clickables.map(function(clickable, i) {
return <MyClickable key={ clickable.name }
name={ clickable.name }
index={ i }
isActive={ this.state.activeIndex === i }
onClick={ this.handleClick }
/>
} )
}
</div>
}
Start with:
setup.exe /?
And you should see a dialog popup with some options displayed.
Your regular expression [^a-zA-Z0-9]\s/g
says match any character that is not a number or letter followed by a space.
Remove the \s and you should get what you are after if you want a _ for every special character.
var newString = str.replace(/[^A-Z0-9]/ig, "_");
That will result in hello_world___hello_universe
If you want it to be single underscores use a + to match multiple
var newString = str.replace(/[^A-Z0-9]+/ig, "_");
That will result in hello_world_hello_universe
Have you tried adding a configsection
handler to your app.config? e.g.
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
If you want to do it one line and you do not want to change list1 or list2 you can do it using stream
List<String> list1 = Arrays.asList("London", "Paris");
List<String> list2 = Arrays.asList("Moscow", "Tver");
List<String> list = Stream.concat(list1.stream(),list2.stream()).collect(Collectors.toList());
temperature = input("What's the current temperature in your city? (please use the format ??C or ???F) >>> ")
### warning... the result from input will <str> on Python 3.x only
### in the case of Python 2.x, the result from input is the variable type <int>
### for the <str> type as the result for Python 2.x it's neccessary to use the another: raw_input()
temp_int = int(temperature[:-1]) # 25 <int> (as example)
temp_str = temperature[-1:] # "C" <str> (as example)
if temp_str.lower() == 'c':
print("Your temperature in Fahrenheit is: {}".format( (9/5 * temp_int) + 32 ) )
elif temp_str.lower() == 'f':
print("Your temperature in Celsius is: {}".format( ((5/9) * (temp_int - 32)) ) )
You could use this: http://getfirebug.com/js.html. It has a profiler for JavaScript.
I saw the same error and solved by switching off the proxy settings in TortoiseSVN that I normally need for commits to the company servers. I installed Subclipse to back up my own non-prime-time stuff to a local repository (using VisualSVN). I use Eclipse Galileo 3.3 and Subclipse 1.6.12.
To do this you need a JDBC Connection and/or driver that supports logging the sql at a low level.
Take a look at log4jdbc
Objects created by new
must be eventually delete
d lest they leak. The destructor won't be called, memory won't be freed, the whole bit. Since C++ has no garbage collection, it's a problem.
Objects created by value (i. e. on stack) automatically die when they go out of scope. The destructor call is inserted by the compiler, and the memory is auto-freed upon function return.
Smart pointers like unique_ptr
, shared_ptr
solve the dangling reference problem, but they require coding discipline and have other potential issues (copyability, reference loops, etc.).
Also, in heavily multithreaded scenarios, new
is a point of contention between threads; there can be a performance impact for overusing new
. Stack object creation is by definition thread-local, since each thread has its own stack.
The downside of value objects is that they die once the host function returns - you cannot pass a reference to those back to the caller, only by copying, returning or moving by value.
This took me a while to figure out, as the conventional window['someFunctionName']()
did not work for me at first. The names of my functions were being pulled as an AJAX response from a database. Also, for whatever reason, my functions were declared outside of the scope of the window, so in order to fix this I had to rewrite the functions I was calling from
function someFunctionName() {}
to
window.someFunctionName = function() {}
and from there I could call window['someFunctionName']()
with ease. I hope this helps someone!
Update - I verified the below works. Maybe the creation of your JArray isn't quite right.

var trendsArray = twitterObject.Children<JProperty>().FirstOrDefault(x => x.Name == "trends").Value;

So call Children on your JArray to get each JObject in JArray. Call Children on each JObject to access the objects properties.
foreach(var item in yourJArray.Children())
{
var itemProperties = item.Children<JProperty>();
//you could do a foreach or a linq here depending on what you need to do exactly with the value

Generally speaking you should not call GC explicitly with System.gc(). There is even the IO lecture (http://www.youtube.com/watch?v=_CruQY55HOk) where they explain what the GC pauses log mean and in which they also state to never call System.gc() because Dalvik knows better than you when to do so.
On the other hand as mentioned in above answers already GC process in Android (like everything else) is sometimes buggy. This means Dalvik GC algorithms are not on par with Hotspot or JRockit JVMs and might get things wrong on some occasions. One of those occasions is when allocating bitmap objects. This is a tricky one because it uses Heap and Non Heap memory and because one loose instance of bitmap object on memory constrained device is enough to give you an OutOfMemory exception. So calling it after you don't need this bitmap any-more is generally suggested by many developers and is even considered good practice by some people.
Better practice is using .recycle() on a bitmap as it is what this method is made for, as it marks native memory of the bitmap as safe to delete. Keep in mind that this is very version dependent, meaning it will generally be required on older Android versions (Pre 3.0 I think) but will not be required on later ones. Also it won't hurt much using it on newer versions ether (just don't do this in a loop or something like that). New ART runtime changed a lot here because they introduced special Heap "partition" for big objects but I think it will not hurt much to do this with ART ether.
Also one very important note about System.gc(). This method is not a command that Dalvik (or JVMs) are obligated to respond to. Consider it more like saying to Virtual machine "Could you please do garbage collection if it's not a hassle".
Maybe this command can be helpful :
git archive --remote=MyRemoteGitRepo --format=tar BranchName_or_commit path/to/your/dir/or/file > files.tar
"Et voilà"
I hope this will be even more elegant way of doing it.
a = [1,2,3,4,5,6]
zip(a[::2], a[1::2])
[(1, 2), (3, 4), (5, 6)]
This is a nice example: The Repository Pattern Example in C#
Basically, repository hides the details of how exactly the data is being fetched/persisted from/to the database. Under the covers:
First of all, excuse me for my English. I would like to share my code, because it works and it is different than the others given anwers. In this exemple,if you speak French (France, Belgium or other french language) you are redirected on the french page, otherwise on the english page, depending on the browser configuration :
<script type="text/javascript">_x000D_
$(document).ready(function () {_x000D_
var userLang = navigator.language || navigator.userLanguage;_x000D_
if (userLang.startsWith("fr")) {_x000D_
window.location.href = '../fr/index.html';_x000D_
}_x000D_
else {_x000D_
window.location.href = '../en/index.html';_x000D_
}_x000D_
});_x000D_
</script>
_x000D_
if the current thread is killed and you use Thread.Sleep
and it is executing then you might get a ThreadAbortException
.
With Task.Delay
you can always provide a cancellation token and gracefully kill it. Thats one reason I would choose Task.Delay
. see http://social.technet.microsoft.com/wiki/contents/articles/21177.visual-c-thread-sleep-vs-task-delay.aspx
I also agree efficiency is not paramount in this case.
You can achieve it:
$(document).ready(function(){
$('#textBox').keyup(function () {alert('changed');});
});
or with change (handle copy paste with right click):
$(document).ready(function(){
$('#textBox2').change(function () {alert('changed');});
});
Here is Demo
A simpler way, if you are using .NET 3.5, is to use XDocument
and XmlSchemaSet
validation.
XmlSchemaSet schemas = new XmlSchemaSet();
schemas.Add(schemaNamespace, schemaFileName);
XDocument doc = XDocument.Load(filename);
string msg = "";
doc.Validate(schemas, (o, e) => {
msg += e.Message + Environment.NewLine;
});
Console.WriteLine(msg == "" ? "Document is valid" : "Document invalid: " + msg);
See the MSDN documentation for more assistance.
jquery.ajax({
url: `//your api url`
type: "GET",
dataType: "json",
success: function(data) {
jQuery.each(data, function(index, value) {
console.log(data);
`All you API data is here`
}
}
});
Use this:
var dict = list.ToDictionary(x => x);
See MSDN for more info.
As Pranay points out in the comments, this will fail if an item exists in the list multiple times.
Depending on your specific requirements, you can either use var dict = list.Distinct().ToDictionary(x => x);
to get a dictionary of distinct items or you can use ToLookup
instead:
var dict = list.ToLookup(x => x);
This will return an ILookup<string, string>
which is essentially the same as IDictionary<string, IEnumerable<string>>
, so you will have a list of distinct keys with each string instance under it.
You can get the window height quite easily in pure CSS, using the units "vh", each corresponding to 1% of the window height. On the example below, let's begin to centralize block.foo by adding a margin-top half the size of the screen.
.foo{
margin-top: 50vh;
}
But that only works for 'window' size. With a dab of javascript, you could make it more versatile.
$(':root').css("--windowHeight", $( window ).height() );
That code will create a CSS variable named "--windowHeight" that carries the height of the window. To use it, just add the rule:
.foo{
margin-top: calc( var(--windowHeight) / 2 );
}
And why is it more versatile than simply using "vh" units? Because you can get the height of any element. Now if you want to centralize a block.foo in any container.bar, you could:
$(':root').css("--containerHeight", $( .bar ).height() );
$(':root').css("--blockHeight", $( .foo ).height() );
.foo{
margin-top: calc( var(--containerHeight) / 2 - var(--blockHeight) / 2);
}
And finally, for it to respond to changes on the window size, you could use (in this example, the container is 50% the window height):
$( window ).resize(function() {
$(':root').css("--containerHeight", $( .bar ).height()*0.5 );
});
The current "pipable" variant of this operator is called finalize()
(since RxJS 6). The older and now deprecated "patch" operator was called finally()
(until RxJS 5.5).
I think finalize()
operator is actually correct. You say:
do that logic only when I subscribe, and after the stream has ended
which is not a problem I think. You can have a single source
and use finalize()
before subscribing to it if you want. This way you're not required to always use finalize()
:
let source = new Observable(observer => {
observer.next(1);
observer.error('error message');
observer.next(3);
observer.complete();
}).pipe(
publish(),
);
source.pipe(
finalize(() => console.log('Finally callback')),
).subscribe(
value => console.log('#1 Next:', value),
error => console.log('#1 Error:', error),
() => console.log('#1 Complete')
);
source.subscribe(
value => console.log('#2 Next:', value),
error => console.log('#2 Error:', error),
() => console.log('#2 Complete')
);
source.connect();
This prints to console:
#1 Next: 1
#2 Next: 1
#1 Error: error message
Finally callback
#2 Error: error message

Remove the directory (basically a copy of https://stackoverflow.com/a/38201611/1695680), Ansible does this operation with rmtree
under the hood.
- name: remove files and directories
file:
state: "{{ item }}"
path: "/srv/deleteme/"
owner: 1000 # set your owner, group, and mode accordingly
group: 1000
mode: '0777'
with_items:
- absent
- directory
If you don't have the luxury of removing the whole directory and recreating it, you can scan it for files, (and directories), and delete them one by one. Which will take a while. You probably want to make sure you have [ssh_connection]\npipelining = True
in your ansible.cfg on.
- block:
- name: 'collect files'
find:
paths: "/srv/deleteme/"
hidden: True
recurse: True
# file_type: any # Added in ansible 2.3
register: collected_files
- name: 'collect directories'
find:
paths: "/srv/deleteme/"
hidden: True
recurse: True
file_type: directory
register: collected_directories
- name: remove collected files and directories
file:
path: "{{ item.path }}"
state: absent
with_items: >
{{
collected_files.files
+ collected_directories.files
}}
Use variables i.e. the .BAT

This kind of thing happened to me when I was using php language construct exit; in middle of transaction. Then this transaction "hangs" and you need to kill mysql process (described above with processlist;)
As Jeffrey Said, you are not checking the value of check()
. In addition, your check()
function is not returning anything. Note the difference:
def check():
with open('example.txt') as f:
datafile = f.readlines()
found = False # This isn't really necessary
for line in datafile:
if blabla in line:
# found = True # Not necessary
return True
return False # Because you finished the search without finding
Then you can test the output of check()
:
if check():
print('True')
else:
print('False')
Trim() works for both sides.

A couple of scenarios might help illustrate the purpose of access and refresh tokens and the engineering trade-offs in designing an oauth2 (or any other auth) system:
In the web app scenario you have a couple of options:
Let's imagine that someone manages to hijack your session. The only thing that is possible is to request your pages.
Comparing 1 and 2:
In 1, access_token and refresh_token only travel over the wire on the way between the authorzation server (google in your case) and your app server. This would be done on a secure channel. A hacker could hijack the session but they would only be able to interact with your web app. In 2, the hacker could take the access_token away and form their own requests to the resources that the user has granted access to. Even if the hacker gets a hold of the access_token they will only have a short window in which they can access the resources.
Either way the refresh_token and clientid/secret are only known to the server making it impossible from the web browser to obtain long term access.
Let's imagine you are implementing oauth2 and set a long timeout on the access token:
In 1) There's not much difference here between a short and long access token since it's hidden in the app server. In 2) someone could get the access_token in the browser and then use it to directly access the user's resources for a long time.
On the mobile, there are a couple of scenarios that I know of:
Store clientid/secret on the device and have the device orchestrate obtaining access to the user's resources.
Use a backend app server to hold the clientid/secret and have it do the orchestration. Use the access_token as a kind of session key and pass it between the client and the app server.
Comparing 1 and 2
In 1) Once you have clientid/secret on the device they aren't secret any more. Anyone can decompile and then start acting as though they are you, with the permission of the user of course. The access_token and refresh_token are also in memory and could be accessed on a compromised device which means someone could act as your app without the user giving their credentials. In this scenario the length of the access_token makes no difference to the hackability since refresh_token is in the same place as access_token. In 2) the clientid/secret nor the refresh token are compromised. Here the length of the access_token expiry determines how long a hacker could access the users resources, should they get hold of it.
Here it depends upon what you're securing with your auth system as to how long your access_token expiry should be. If it's something particularly valuable to the user it should be short. Something less valuable, it can be longer.
Some people like google don't expire the refresh_token. Some like stackflow do. The decision on the expiry is a trade-off between user ease and security. The length of the refresh token is related to the user return length, i.e. set the refresh to how often the user returns to your app. If the refresh token doesn't expire the only way they are revoked is with an explicit revoke. Normally, a log on wouldn't revoke.
Hope that rather length post is useful.
open terminal and type
sudo sh -c 'echo /usr/local/mysql/bin > /etc/paths.d/mysql'
then close terminal and open a new terminal and type
mysql -u root -p
hit enter, and it will ask you for password

To handle many newline delimiters, including character combinations like \r\n
, use splitlines.
Combine join and splitlines to remove/replace all newlines from a string s
:
''.join(s.splitlines())
To remove exactly one trailing newline, pass True
as the keepends
argument to retain the delimiters, removing only the delimiters on the last line:
def chomp(s):
if len(s):
lines = s.splitlines(True)
last = lines.pop()
return ''.join(lines + last.splitlines())
else:
return ''
After like 48 hours of research, I ended up doing this to get proportional scaling:
NOTE: This sample is written with React. If you aren't using that, change the camel case stuff back to hyphens (ie: change backgroundColor
to background-color
and change the style Object
back to a String
).
<div
style={{
backgroundColor: 'lightpink',
resize: 'horizontal',
overflow: 'hidden',
width: '1000px',
height: 'auto',
}}
>
<svg
width="100%"
viewBox="113 128 972 600"
preserveAspectRatio="xMidYMid meet"
>
<g> ... </g>
</svg>
</div>
Here's what is happening in the above sample code:
VIEWBOX
MDN: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/viewBox
min-x, min-y, width and height
ie: viewbox="0 0 1000 1000"
Viewbox is an important attribute because it basically tells the SVG what size to draw and where. If you used CSS to make the SVG 1000x1000 px but your viewbox was 2000x2000, you would see the top-left quarter of your SVG.
The first two numbers, min-x and min-y, determine if the SVG should be offset inside the viewbox.
My SVG needs to shift up/down or left/right
Examine this: viewbox="50 50 450 450"
The first two numbers will shift your SVG left 50px and up 50px, and the second two numbers are the viewbox size: 450x450 px. If your SVG is 500x500 but it has some extra padding on it, you can manipulate those numbers to move it around inside the "viewbox".
Your goal at this point is to change one of those numbers and see what happens.
You can also completely omit the viewbox, but then your milage will vary depending on every other setting you have at the time. In my experience, you will encounter issues with preserving aspect ratio because the viewbox helps define the aspect ratio.
PRESERVE ASPECT RATIO
MDN: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/preserveAspectRatio
Based on my research, there are lots of different aspect ratio settings, but the default one is called xMidYMid meet
. I put it on mine to explicitly remind myself. xMidYMid meet
makes it scale proportionately based on the midpoint X and Y. This means it stays centered in the viewbox.
WIDTH
MDN: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/width
Look at my example code above. Notice how I set only width, no height. I set it to 100% so it fills the container it is in. This is what is probably contributing the most to answering this Stack Overflow question.
You can change it to whatever pixel value you want, but I'd recommend using 100% like I did to blow it up to max size and then control it with CSS via the parent container. I recommend this because you will get "proper" control. You can use media queries and you can control the size without crazy JavaScript.
SCALING WITH CSS
Look at my example code above again. Notice how I have these properties:
resize: 'horizontal', // you can safely omit this
overflow: 'hidden', // if you use resize, use this to fix weird scrollbar appearance
width: '1000px',
height: 'auto',
This is additional, but it shows you how to allow the user to resize the SVG while maintaining the proper aspect ratio. Because the SVG maintains its own aspect ratio, you only need to make width resizable on the parent container, and it will resize as desired.
We leave height alone and/or set it to auto, and we control the resizing with width. I picked width because it is often more meaningful due to responsive designs.
Here is an image of these settings being used:
If you read every solution in this question and are still confused or don't quite see what you need, check out this link here. I found it very helpful:
https://css-tricks.com/scale-svg/
It's a massive article, but it breaks down pretty much every possible way to manipulate an SVG, with or without CSS. I recommend reading it while casually drinking a coffee or your choice of select liquids.
It is going to write the value of your property model.Destination
This is by design. You'll want to populate your Destination property with the value you want in your controller before returning your view.
Try:
$articles = DB::table('articles')
->select('articles.id as articles_id', ..... )
->join('categories', 'articles.categories_id', '=', 'categories.id')
->join('users', 'articles.user_id', '=', 'user.id')
->get();
You can use LIMIT 2,1
instead of WHERE row_number() = 3
.
As the documentation explains, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return.
Keep in mind that it's an 0-based index. So, if you want the line number n, the first argument should be n-1. The second argument will always be 1, because you just want one row. For example, if you want the line number 56 of a table customer
:
SELECT * FROM customer LIMIT 55,1
If you want to cater to 1-word cell, use this... based upon astander's
=IFERROR(LEFT(A1,SEARCH(" ",A1)-1),A1)
Best solution is to put a div into table cell with zero width. Tbody table cells will inherit their widths from widths defined the thead. Position:relative and negative margin should do the trick!
Here is a screenshot: https://flic.kr/p/nvRs4j
<body>
<!-- SOME CSS -->
<style>
.cropped-table-cells,
.cropped-table-cells tr td {
margin:0px;
padding:0px;
border-collapse:collapse;
}
.cropped-table-cells tr td {
border:1px solid lightgray;
padding:3px 5px 3px 5px;
}
.no-overflow {
display:inline-block;
white-space:nowrap;
position:relative; /* must be relative */
width:100%; /* fit to table cell width */
margin-right:-1000px; /* technically this is a less than zero width object */
overflow:hidden;
}
</style>
<!-- CROPPED TABLE BODIES -->
<table class="cropped-table-cells">
<thead>
<tr>
<td style="width:100px;" width="100"><span>ORDER<span></td>

Just had a similar problem, except i needed a NodeList and not a Document, here's what I came up with. It's mostly the same solution as before, augmented to get the root element down as a NodeList and using erickson's suggestion of using an InputSource instead for character encoding issues.
private String DOC_ROOT="root";
String xml=getXmlString();
Document xmlDoc=loadXMLFrom(xml);
Element template=xmlDoc.getDocumentElement();
NodeList nodes=xmlDoc.getElementsByTagName(DOC_ROOT);
public static Document loadXMLFrom(String xml) throws Exception {
InputSource is= new InputSource(new StringReader(xml));
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
DocumentBuilder builder = null;
builder = factory.newDocumentBuilder();
Document doc = builder.parse(is);
return doc;
}
“CURL ERROR 7 Failed to connect to Permission denied” error is caused, when for any reason curl request is blocked by some firewall or similar thing.
you will face this issue when ever the curl request is not with standard ports.
for example if you do curl to some URL which is on port 1234, you will face this issue where as URL with port 80 will give you results easily.
Most commonly this error has been seen on CentOS and any other OS with ‘SElinux’.
you need to either disable or change ’SElinux’ to permissive
have a look on this one

Hope this helps
While a lot of others should be mentioned, Apache Wicket should be preferred.
Wicket doesn't just reduce lots of boilerplate code, it actually removes it entirely and you can work with excellent separation of business code and markup without mixing the two and a wide variety of other things you can read about from the website.
Always use parseInt
with a radix (base) as the second parameter, or you will get unexpected results:
var number = parseInt($(this).find('.number').text(), 10);
A popular variation however is to use +
as a unitary operator. This will always convert with base 10 and never throw an error, just return zero NaN
which can be tested with the function isNaN()
if it's an invalid number:
var number = +($(this).find('.number').text());
You're mixing if statement with a ternary expression, that's why you're having a syntax error. It might be easier for you to understand what's going on if you extract mapping function outside of your render method:
renderItem = (id) => {
// just standard if statement
if (this.props.schema.collectionName.length < 0) {
return (
<Expandable>
<ObjectDisplay
key={id}
parentDocumentId={id}
schema={schema[this.props.schema.collectionName]}
value={this.props.collection.documents[id]}
/>
</Expandable>
);
}
return (
<h1>hejsan</h1>
);
}
Then just call it when mapping:
render() {
return (
<div>
<div className="box">
{
this.props.collection.ids
.filter(
id =>
// note: this is only passed when in top level of document
this.props.collection.documents[id][
this.props.schema.foreignKey
] === this.props.parentDocumentId
)
.map(this.renderItem)
}
</div>
</div>
)
}
Of course, you could have used the ternary expression as well, it's a matter of preference. What you use, however, affects the readability, so make sure to check different ways and tips to properly do conditional rendering in react and react native.
Do it like this. This approach lets you search a file of any size (big size won't crash the script) and will return ALL lines that match the string you want.
<?php
$searchthis = "mystring";
$matches = array();
$handle = @fopen("path/to/inputfile.txt", "r");
if ($handle)
{
while (!feof($handle))
{
$buffer = fgets($handle);
if(strpos($buffer, $searchthis) !== FALSE)
$matches[] = $buffer;
}
fclose($handle);
}
//show results:
print_r($matches);
?>
Note the way strpos
is used with !==
operator.
Source: CodePath - UI Testing With Espresso
- Finally, we need to pull in the Espresso dependencies and set the test runner in our app build.gradle:
// build.gradle
...
android {
...
defaultConfig {
...
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
}
dependencies {
...
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2') {
// Necessary if your app targets Marshmallow (since Espresso
// hasn't moved to Marshmallow yet)
exclude group: 'com.android.support', module: 'support-annotations'
}
androidTestCompile('com.android.support.test:runner:0.5') {
// Necessary if your app targets Marshmallow (since the test runner
// hasn't moved to Marshmallow yet)
exclude group: 'com.android.support', module: 'support-annotations'
}
}
I've added that to my gradle file and the warning disappeared.
Also, if you get any other dependency listed as conflicting, such as support-annotations, try excluding it too from the androidTestCompile dependencies.
If you're using SQL Server, after your query you can select the @@RowCount function (or if your result set might have more than 2 billion rows use the RowCount_Big() function). This will return the number of rows selected by the previous statement or number of rows affected by an insert/update/delete statement.
SELECT my_table.my_col
FROM my_table
WHERE my_table.foo = 'bar'
SELECT @@Rowcount
Or if you want to row count included in the result sent similar to Approach #2, you can use the the OVER clause.
SELECT my_table.my_col,
count(*) OVER(PARTITION BY my_table.foo) AS 'Count'
FROM my_table
WHERE my_table.foo = 'bar'
Using the OVER clause will have much better performance than using a subquery to get the row count. Using the @@RowCount will have the best performance because the there won't be any query cost for the select @@RowCount statement
Update in response to comment: The example I gave would give the # of rows in partition - defined in this case by "PARTITION BY my_table.foo". The value of the column in each row is the # of rows with the same value of my_table.foo. Since your example query had the clause "WHERE my_table.foo = 'bar'", all rows in the resultset will have the same value of my_table.foo and therefore the value in the column will be the same for all rows and equal (in this case) this the # of rows in the query.
Here is a better/simpler example of how to include a column in each row that is the total # of rows in the resultset. Simply remove the optional Partition By clause.
SELECT my_table.my_col, count(*) OVER() AS 'Count'
FROM my_table
WHERE my_table.foo = 'bar'
I like using a package.json file in the root of your app folder.
Here is one I use
nvm use v0.6.4
npm install
Because you didn't specify the Header.
I've added an extended example:
var request = (HttpWebRequest)WebRequest.Create(strServer + strURL.Split('&')[1].ToString());
Header(ref request, p_Method);
And the method Header:
private void Header(ref HttpWebRequest p_request, string p_Method)
{
p_request.ContentType = "application/x-www-form-urlencoded";
p_request.Method = p_Method;
p_request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows CE)";
p_request.Host = strServer.Split('/')[2].ToString();
p_request.Accept = "*/*";
if (String.IsNullOrEmpty(strURLReferer))
{
p_request.Referer = strServer;
}
else
{
p_request.Referer = strURLReferer;
}
p_request.Headers.Add("Accept-Language", "en-us\r\n");
p_request.Headers.Add("UA-CPU", "x86 \r\n");
p_request.Headers.Add("Cache-Control", "no-cache\r\n");
p_request.KeepAlive = true;
}
What have you tried, what was the problem?
Creating DataColumns
and add values to a DataTable
is straight forward:
Dim dt = New DataTable()
Dim dcID = New DataColumn("ID", GetType(Int32))
Dim dcName = New DataColumn("Name", GetType(String))
dt.Columns.Add(dcID)
dt.Columns.Add(dcName)
For i = 1 To 1000
dt.Rows.Add(i, "Row #" & i)
Next
Edit:
If you want to read a xml file and load a DataTable from it, you can use DataTable.ReadXml
.

Context: http, serverSets the maximum

A request header field cannot exceed the size of one buffer as well, or the 400 (Bad Request) error is returned to the client. Buffers are allocated only on demand. By default, the buffer size is equal to 8K bytes. If after the end of request processing a connection is transitioned into the keep-alive state, these buffers are released.
so you need to change the size parameter at the end of that line to something bigger for your needs.
I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)
public static bool IsStringType(object data)
{
return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
}

To address the --rebase
vs. --merge
option:
Let's say you have super repository A and submodule B and want to do some work in submodule B. You've done your homework and know that after calling
git submodule update
you are in a HEAD-less state, so any commits you do at this point are hard to get back to. So, you've started work on a new branch in submodule B
cd B
git checkout -b bestIdeaForBEver
<do work>
Meanwhile, someone else in project A has decided that the latest and greatest version of B is really what A deserves. You, out of habit, merge the most recent changes down and update your submodules.
<in A>
git merge develop
git submodule update
Oh noes! You're back in a headless state again, probably because B is now pointing to the SHA associated with B's new tip, or some other commit. If only you had:
git merge develop
git submodule update --rebase
Fast-forwarded bestIdeaForBEver to b798edfdsf1191f8b140ea325685c4da19a9d437.
Submodule path 'B': rebased into 'b798ecsdf71191f8b140ea325685c4da19a9d437'
Now that best idea ever for B has been rebased onto the new commit, and more importantly, you are still on your development branch for B, not in a headless state!
(The --merge
will merge changes from beforeUpdateSHA to afterUpdateSHA into your working branch, as opposed to rebasing your changes onto afterUpdateSHA.)
For hibernate it is important to know that your object WILL have an id, when you want to persist/save it. Thus, make sure that
private String U_id;
will have a value, by the time you are going to persist your object. You can do that with the @GeneratedValue
annotation or by assigning a value manually.
In the case you need or want to assign your id's manually (and that's what the above error is actually about), I would prefer passing the values for the fields to your constructor, at least for U_id
, e.g.
public Role (String U_id) { ... }
This ensures that your object has an id, by the time you have instantiated it. I don't know what your use case is and how your application behaves in concurrency, however, in some cases this is not recommended. You need to ensure that your id is unique.
Further note: Hibernate will still require a default constructor, as stated in the hibernate documentation. In order to prevent you (and maybe other programmers if you're designing an api) of instantiations of Role
using the default constructor, just declare it as private
.
Crossframe-Scripting is not possible when the two frames have different domains -> Security.
See this: http://javascript.about.com/od/reference/a/frame3.htm
Now to answer your question: there is no solution or work around, you simply should check your website-design why there must be two frames from different domains that changes the url of the other one.
the following two ways work well:
C:\>mongodb\bin\mongoimport --jsonArray -d test -c docs --file example2.json
C:\>mongodb\bin\mongoimport --jsonArray -d test -c docs < example2.json
if the collections are under a specific user, you can use -u -p --authenticationDatabase
Unless you are subtracting dates on same browser client and don't care about edge cases like day light saving time changes, you are probably better off using moment.js which offers powerful localized APIs. For example, this is what I have in my utils.js:
subtractDates: function(date1, date2) {
return moment.subtract(date1, date2).milliseconds();
},
millisecondsSince: function(dateSince) {
return moment().subtract(dateSince).milliseconds();
},
Tensorflow also implemented functions for resizing/padding images tf.image.pad tf.pad.
padded_image = tf.image.pad_to_bounding_box(image, top_padding, left_padding, target_height, target_width)
padded_image = tf.pad(image, paddings, "CONSTANT")
These functions work just like other input-pipeline features of tensorflow and will work much better for machine learning applications.
function in_array(what, where) {
var a=false;
for (var i=0; i<where.length; i++) {
if(what == where[i]) {
a=true;
break;
}
}
return a;
}
I used String
and I converted initially the int
to String
.Then I used the reverse method. I found the reverse of the number in String
and then I converted the string back to int
. Here is the program.
import java.util.*;
public class Panathinaikos {
public static void my_try()
{
Scanner input = new Scanner(System.in);
System.out.println("Enter the number you want to be reversed");
int number = input.nextInt();
String sReverse = Integer.toString(number);
String reverse = new StringBuffer(sReverse).reverse().toString();
int Reversed = Integer.parseInt(reverse);
System.out.print("The number " + number+ " reversed is " + Reversed);
}
}
You can also get them with pure javascript.
For example:
new URL(location.href).searchParams.get('page')
For this url: websitename.com/user/?page=1, it would return a value of 1
You can also set DirectoryIndex in apache's httpd.conf file.
CentOS keeps this file in /etc/httpd/conf/httpd.conf
Debian: /etc/apache2/apache2.conf
Open the file in your text editor and find the line starting with DirectoryIndex
To load landing.html as a default (but index.html if that's not found) change this line to read:
DirectoryIndex landing.html index.html
After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.
It's incorrect to use zeros in date or in datetime, just put null instead of zeros.
You'll have to use JS to open the popup, though you can put it on the page conditionally with PHP, you're right that you'll have to use a JavaScript function.
Another scenario where this error is trigered due syntax error:
ucwords($variable) = $string;
For php7.0-fpm I call:
service php7.0-fpm status
php7.0-fpm start/running, process 25993
Now watch for the good part. The process name is actually php-fpm7.0
echo `/bin/pidof php-fpm7.0`
26334 26297 26286 26285 26282
Class methods can't change or know the value of any instance variable. That should be the criteria for knowing if an instance method can be a class method.
Some times you may need to update parent properties directly within child scope. e.g. need to save a date and time of parent control after changes by a child controller. e.g Code in JSFiddle
HTML
<div ng-app>
<div ng-controller="Parent">
event.date = {{event.date}} <br/>
event.time = {{event.time}} <br/>
<div ng-controller="Child">
event.date = {{event.date}}<br/>
event.time = {{event.time}}<br/>
<br>
event.date: <input ng-model='event.date'><br>
event.time: <input ng-model='event.time'><br>
</div>
</div>
JS
function Parent($scope) {
$scope.event = {
date: '2014/01/1',
time: '10:01 AM'
}
}
function Child($scope) {
}
select * into x_history from your_table_here;
truncate table your_table_here;
Something along these lines, using ABC
import abc
class Shape(object):
__metaclass__ = abc.ABCMeta
@abc.abstractmethod
def method_to_implement(self, input):
"""Method documentation"""
return
Also read this good tutorial: http://www.doughellmann.com/PyMOTW/abc/
You can also check out zope.interface which was used prior to introduction of ABC in python.
As others have said, you are likely reading past the end of the file as you're only checking for x != ' '
. Instead you also have to check for EOF in the inner loop (but in this case don't use a char, but a sufficiently large type):
while ( ! file.eof() )
{
std::ifstream::int_type x = file.get();
while ( x != ' ' && x != std::ifstream::traits_type::eof() )
{
word += static_cast<char>(x);
x = file.get();
}
std::cout << word << '\n';
word.clear();
}
But then again, you can just employ the stream's streaming operators, which already separate at whitespace (and better account for multiple spaces and other kinds of whitepsace):
void readFile( )
{
std::ifstream file("program.txt");
for(std::string word; file >> word; )
std::cout << word << '\n';
}
And even further, you can employ a standard algorithm to get rid of the manual loop altogether:
#include <algorithm>
#include <iterator>
void readFile( )
{
std::ifstream file("program.txt");
std::copy(std::istream_iterator<std::string>(file),
std::istream_itetator<std::string>(),
std::ostream_iterator<std::string>(std::cout, "\n"));
}
From my perspective the question is pretty good as the same approach would be used not only for the "Login" window, but for any kind of window. I've reviewed a lot of suggestions and none are OK for me. Please review my suggestion that was taken from the MVVM design pattern article.
Each ViewModel class should inherit from WorkspaceViewModel
that has the RequestClose
event and CloseCommand
property of the ICommand
type. The default implementation of the CloseCommand
property will raise the RequestClose
event.
In order to get the window closed, the OnLoaded
method of your window should be overridden:
void CustomerWindow_Loaded(object sender, RoutedEventArgs e)
{
CustomerViewModel customer = CustomerViewModel.GetYourCustomer();
DataContext = customer;
customer.RequestClose += () => { Close(); };
}
or OnStartup
method of you app:
protected override void OnStartup(StartupEventArgs e)
{
base.OnStartup(e);
MainWindow window = new MainWindow();
var viewModel = new MainWindowViewModel();
viewModel.RequestClose += window.Close;
window.DataContext = viewModel;
window.Show();
}
I guess that RequestClose
event and CloseCommand
property implementation in the WorkspaceViewModel
are pretty clear, but I will show them to be consistent:
public abstract class WorkspaceViewModel : ViewModelBase
// There's nothing interesting in ViewModelBase as it only implements the INotifyPropertyChanged interface
{
RelayCommand _closeCommand;
public ICommand CloseCommand
{
get
{
if (_closeCommand == null)
{
_closeCommand = new RelayCommand(
param => Close(),
param => CanClose()
);
}
return _closeCommand;
}
}
public event Action RequestClose;
public virtual void Close()
{
if ( RequestClose != null )
{
RequestClose();
}
}
public virtual bool CanClose()
{
return true;
}
}
And the source code of the RelayCommand
:
public class RelayCommand : ICommand
{
#region Constructors
public RelayCommand(Action<object> execute, Predicate<object> canExecute)
{
if (execute == null)
throw new ArgumentNullException("execute");
_execute = execute;
_canExecute = canExecute;
}
#endregion // Constructors
#region ICommand Members
[DebuggerStepThrough]
public bool CanExecute(object parameter)
{
return _canExecute == null ? true : _canExecute(parameter);
}
public event EventHandler CanExecuteChanged
{
add { CommandManager.RequerySuggested += value; }
remove { CommandManager.RequerySuggested -= value; }
}
public void Execute(object parameter)
{
_execute(parameter);
}
#endregion // ICommand Members
#region Fields
readonly Action<object> _execute;
readonly Predicate<object> _canExecute;
#endregion // Fields
}
P.S. Don't treat me badly for those sources! If I had them yesterday that would have saved me a few hours...
P.P.S. Any comments or suggestions are welcome.
Just to clarify this: if we have a RadioGroup
with several RadioButtons
and need to activate one by index, implies that:
radioGroup.check(R.id.radioButtonId)
and
radioGroup.getChildAt(index)`
We can to do:
radioGroup.check(radioGroup.getChildAt(index).getId());
Each instantiation and full specialization of std::atomic<> represents a type that different threads can simultaneously operate on (their instances), without raising undefined behavior:
Objects of atomic types are the only C++ objects that are free from data races; that is, if one thread writes to an atomic object while another thread reads from it, the behavior is well-defined.
In addition, accesses to atomic objects may establish inter-thread synchronization and order non-atomic memory accesses as specified by
std::memory_order
.
std::atomic<>
wraps operations that, in pre-C++ 11 times, had to be performed using (for example) interlocked functions with MSVC or atomic bultins in case of GCC.
Also, std::atomic<>
gives you more control by allowing various memory orders that specify synchronization and ordering constraints. If you want to read more about C++ 11 atomics and memory model, these links may be useful:
Note that, for typical use cases, you would probably use overloaded arithmetic operators or another set of them:
std::atomic<long> value(0);
value++; //This is an atomic op
value += 5; //And so is this
Because operator syntax does not allow you to specify the memory order, these operations will be performed with std::memory_order_seq_cst
, as this is the default order for all atomic operations in C++ 11. It guarantees sequential consistency (total global ordering) between all atomic operations.
In some cases, however, this may not be required (and nothing comes for free), so you may want to use more explicit form:
std::atomic<long> value {0};
value.fetch_add(1, std::memory_order_relaxed); // Atomic, but there are no synchronization or ordering constraints
value.fetch_add(5, std::memory_order_release); // Atomic, performs 'release' operation
Now, your example:
a = a + 12;
will not evaluate to a single atomic op: it will result in a.load()
(which is atomic itself), then addition between this value and 12
and a.store()
(also atomic) of final result. As I noted earlier, std::memory_order_seq_cst
will be used here.
However, if you write a += 12
, it will be an atomic operation (as I noted before) and is roughly equivalent to a.fetch_add(12, std::memory_order_seq_cst)
.
As for your comment:
A regular
int
has atomic loads and stores. Whats the point of wrapping it withatomic<>
?
Your statement is only true for architectures that provide such guarantee of atomicity for stores and/or loads. There are architectures that do not do this. Also, it is usually required that operations must be performed on word-/dword-aligned address to be atomic std::atomic<>
is something that is guaranteed to be atomic on every platform, without additional requirements. Moreover, it allows you to write code like this:
void* sharedData = nullptr;
std::atomic<int> ready_flag = 0;
// Thread 1
void produce()
{
sharedData = generateData();
ready_flag.store(1, std::memory_order_release);
}
// Thread 2
void consume()
{
while (ready_flag.load(std::memory_order_acquire) == 0)
{
std::this_thread::yield();
}
assert(sharedData != nullptr); // will never trigger
processData(sharedData);
}
Note that assertion condition will always be true (and thus, will never trigger), so you can always be sure that data is ready after while
loop exits. That is because:
store()
to the flag is performed after sharedData
is set (we assume that generateData()
always returns something useful, in particular, never returns NULL
) and uses std::memory_order_release
order:
memory_order_release
A store operation with this memory order performs the release operation: no reads or writes in the current thread can be reordered after this store. All writes in the current thread are visible in other threads that acquire the same atomic variable
sharedData
is used after while
loop exits, and thus after load()
from flag will return a non-zero value. load()
uses std::memory_order_acquire
order:
std::memory_order_acquire
A load operation with this memory order performs the acquire operation on the affected memory location: no reads or writes in the current thread can be reordered before this load. All writes in other threads that release the same atomic variable are visible in the current thread.
This gives you precise control over the synchronization and allows you to explicitly specify how your code may/may not/will/will not behave. This would not be possible if only guarantee was the atomicity itself. Especially when it comes to very interesting sync models like the release-consume ordering.
Let's say we have a string called yourstring:
for x in range(0, [howmanytimes you want it at the beginning]):
yourstring = "L" + yourstring
for x in range(0, [howmanytimes you want it at the end]):
yourstring += "L"
Demo:
$exePath = $env:NGINX_HOME + '/nginx.exe'
$myArgs = $args.Clone()
$myArgs += '-p'
$myArgs += $env:NGINX_HOME
& $exepath $myArgs

We can use attribute selector in DOM by using document.querySelector()
and document.querySelectorAll()
methods.
for yours:
document.querySelector("[myAttribute='aValue']");
and by using querySelectorAll()
:
document.querySelectorAll("[myAttribute='aValue']");
In querySelector()
and querySelectorAll()
methods we can select objects as we select in "CSS".
More about "CSS" attribute selectors in https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors
The javaw.exe command is identical to java.exe, except that with javaw.exe there is no associated console window
I use @Thiho answer but i get this error:
'git' is not recognized as an internal or external command
For solving that i use this steps:
I add the following paths to PATH:
C:\Program Files\Git\bin\
C:\Program Files\Git\cmd\
In windows 7:
Finally close and re-open your console.
I got this error when I tried to print a page in a popup. The print dialog was show and it still waiting my acceptance or cancellation of the printing in the popup while in the master page also was waiting in the background showing the message CAUTION provisional headers are shown when I tried to click another link.
In my case the solution was to remove the window.print ();
script that it was executing on the <body>
of the popup window to prevent the print dialog.
I have also got stuck into this and believe me disabling SELinux is not a good idea.
Please just use below and you are good,
sudo restorecon -R /var/www/mysite
Enjoy..
Another solution is passing the read function to the constructor of Readable (cf doc stream readeable options)
var s = new Readable({read(size) {
this.push("your string here")
this.push(null)
}});
you can after use s.pipe for exemple
You can use a native and convenient function Array.prototype.findIndex()
basically:
The findIndex() method returns an index in the array, if an element in the array satisfies the provided testing function. Otherwise -1 is returned.
Just a note it is not supported on Internet Explorer, Opera and Safari, but you can use a Polyfill provided in the link below.
More information:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/findIndex
var hello = {_x000D_
hello: 'world',_x000D_
foo: 'bar'_x000D_
};_x000D_
var qaz = {_x000D_
hello: 'stevie',_x000D_
foo: 'baz'_x000D_

in viewDidLoad
, add this line:
self.tableView.separatorColor = [UIColor clearColor];
and in cellForRowAtIndexPath
:
for iOS lower versions
if(indexPath.row != self.newCarArray.count-1){
UIImageView *line = [[UIImageView alloc] initWithFrame:CGRectMake(0, 44, 320, 2)];
line.backgroundColor = [UIColor redColor];
[cell addSubview:line];
}
for iOS 7 upper versions (including iOS 8)
if (indexPath.row == self.newCarArray.count-1) {
cell.separatorInset = UIEdgeInsetsMake(0.f, cell.bounds.size.width, 0.f, 0.f);
}
As you've indicated, you can't output NULL in an excel formula. I think this has to do with the fact that the formula itself causes the cell to not be able to be NULL. "" is the next best thing, but sometimes it's useful to use 0.
--EDIT--
Based on your comment, you might want to check out this link. http://peltiertech.com/WordPress/mind-the-gap-charting-empty-cells/
It goes in depth on the graphing issues and what the various values represent, and how to manipulate their output on a chart.
I'm not familiar with VSTO I'm afraid. So I won't be much help there. But if you are really placing formulas in the cell, then there really is no way. ISBLANK() only tests to see if a cell is blank or not, it doesn't have a way to make it blank. It's possible to write code in VBA (and VSTO I imagine) that would run on a worksheet_change event and update the various values instead of using formulas. But that would be cumbersome and performance would take a hit.

I came across the same issue recently. I had to insert new rows in a document with hidden rows and faced the same issues with you. After some search and some emails in apache poi list, it seems like a bug in shiftrows() when a document has hidden rows.
The code you are talking about sounds like ServiceLoader
, which was introduced in Java 6 to support a feature that has been defined since Java 1.3 or earlier. For performance reasons, this is the recommended approach to find interface implementations at runtime; if you need support for this in an older version of Java, I hope that you'll find my implementation helpful.
There are a couple of implementations of this in earlier versions of Java, but in the Sun packages, not in the core API (I think there are some classes internal to ImageIO that do this). As the code is simple, I'd recommend providing your own implementation rather than relying on non-standard Sun code which is subject to change.

You will need to set the permissions every time you plug the converter in. I use PuTTY to connect. In order to do so, I have created a little Bash script to sort out the permissions and launch PuTTY:
#!/bin/bash
sudo chmod 666 /dev/ttyUSB0
putty
P.S. I would never recommend that permissions are set to 777.

Explanation: the linking is dependent on the order of modules. Symbols are first requested, and then linked in from a library that has them. So you have to specify modules that use libraries first, and libraries after them. Like this:
gcc x.o y.o z.o -la -lb -lc
Moreover, in case there's a circular dependency, you should specify the same library on the command line several times. So in case libb
needs symbol from libc
and libc
needs symbol from libb
, the command line should be:
gcc x.o y.o z.o -la -lb -lc -lb
Here is my approach that you may try:
import numpy as np
import matplotlib.pyplot as plt
w=10
h=10
fig=plt.figure(figsize=(8, 8))
columns = 4
rows = 5
for i in range(1, columns*rows +1):
img = np.random.randint(10, size=(h,w))
fig.add_subplot(rows, columns, i)
plt.imshow(img)
plt.show()
The resulting image:

Edit 1
Since this answer is popular beyond my expectation. And I see that a small change is needed to enable flexibility for the manipulation of the individual plots. So that I offer this new version to the original code. In essence, it provides:-
New code:
import numpy as np
import matplotlib.pyplot as plt
w = 10
h = 10
fig = plt.figure(figsize=(9, 13))
columns = 4
rows = 5
# prep (x,y) for extra plotting
xs = np.linspace(0, 2*np.pi, 60) # from 0 to 2pi
ys = np.abs(np.sin(xs)) # absolute of sine
# ax enables access to manipulate each of subplots
ax = []
for i in range(columns*rows):
img = np.random.randint(10, size=(h,w))
# create subplot and append to ax
ax.append( fig.add_subplot(rows, columns, i+1) )
ax[-1].set_title("ax:"+str(i)) # set title
plt.imshow(img, alpha=0.25)
# do extra plots on selected axes/subplots
# note: index starts with 0
ax[2].plot(xs, 3*ys)
ax[19].plot(ys**2, xs)
plt.show() # finally, render the plot
The resulting plot:
Edit 2
In the previous example, the code provides access to the sub-plots with single index, which is inconvenient when the figure has many rows/columns of sub-plots. Here is an alternative of it. The code below provides access to the sub-plots with [row_index][column_index]
, which is more suitable for manipulation of array of many sub-plots.
import matplotlib.pyplot as plt
import numpy as np
# settings
h, w = 10, 10 # for raster image
nrows, ncols = 5, 4 # array of sub-plots
figsize = [6, 8] # figure size, inches
# prep (x,y) for extra plotting on selected sub-plots
xs = np.linspace(0, 2*np.pi, 60) # from 0 to 2pi
ys = np.abs(np.sin(xs)) # absolute of sine
# create figure (fig), and array of axes (ax)
fig, ax = plt.subplots(nrows=nrows, ncols=ncols, figsize=figsize)
# plot simple raster image on each sub-plot
for i, axi in enumerate(ax.flat):
# i runs from 0 to (nrows*ncols-1)
# axi is equivalent with ax[rowid][colid]
img = np.random.randint(10, size=(h,w))
axi.imshow(img, alpha=0.25)
# get indices of row/column
rowid = i // ncols
colid = i % ncols
# write row/col indices as axes' title for identification
axi.set_title("Row:"+str(rowid)+", Col:"+str(colid))
# one can access the axes by ax[row_id][col_id]
# do additional plotting on ax[row_id][col_id] of your choice
ax[0][2].plot(xs, 3*ys, color='red', linewidth=3)
ax[4][3].plot(ys**2, xs, color='green', linewidth=3)
plt.tight_layout(True)
plt.show()
The resulting plot:
The following code works:
@Override
protected synchronized void onDraw(Canvas canvas)
{
int stars = getNumStars();
float rating = getRating();
try
{
bitmapWidth = getWidth() / stars;
}
catch (Exception e)
{
bitmapWidth = getWidth();
}
float x = 0;
for (int i = 0; i < stars; i++)
{
Bitmap bitmap;
Resources res = getResources();
Paint paint = new Paint();
if ((int) rating > i)
{
bitmap = BitmapFactory.decodeResource(res, starColor);
}
else
{
bitmap = BitmapFactory.decodeResource(res, starDefault);
}
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, getHeight(), getHeight(), true);
canvas.drawBitmap(scaled, x, 0, paint);
canvas.save();
x += bitmapWidth;
}
super.onDraw(canvas);
}

Worked for us, hope this helps someone.
I solved it by doing like that:
var return_first = (function () {
var tmp = $.ajax({
'type': "POST",
'dataType': 'html',
'url': "ajax.php?first",
'data': { 'request': "", 'target': arrange_url, 'method':
method_target },
'success': function (data) {
tmp = data;
}
}).done(function(data){
return data;
});
return tmp;
});
I know this has already been answered, but I found a new way to align them nicely - with an extra benefit - see http://www.gargan.org/en/Web_Development/Form_Layout_with_CSS/
basically you use the label element around the input and align using that:
<label><span>Name</span> <input /></label>
<label><span>E-Mail</span> <input /></label>
<label><span>Comment</span> <textarea></textarea></label>
and then with css you simply align:
label {
display:block;
position:relative;
}
label span {
font-weight:bold;
position:absolute;
left: 3px;
}
label input, label textarea, label select {
margin-left: 120px;
}
From the stack trace it's clear that, the ThreadPoolExecutor > Worker thread started and it's waiting for the task to be available on the BlockingQueue(DelayedWorkQueue) to pick the task and execute.So this thread will be in WAIT status only as long as get a SIGNAL from the publisher thread.
for one in range(97,110):
print chr(one)
The other answers are correct. However, I sometimes find that I want to open the figure object later. For example, I might want to change the label sizes, add a grid, or do other processing. In a perfect world, I would simply rerun the code generating the plot, and adapt the settings. Alas, the world is not perfect. Therefore, in addition to saving to PDF or PNG, I add:
with open('some_file.pkl', "wb") as fp:
pickle.dump(fig, fp, protocol=4)
Like this, I can later load the figure object and manipulate the settings as I please.
I also write out the stack with the source-code and locals()
dictionary for each function/method in the stack, so that I can later tell exactly what generated the figure.
NB: Be careful, as sometimes this method generates huge files.
I believe however if you combine all of your statements and run it in Java 8.1 you will get a different answer, at least that's what my experience says.
The code will work like this:
int a=5,i;
i=++a + ++a + a++; /*a = 5;
i=++a + ++a + a++; =>
i=6 + 7 + 7; (a=8); i=20;*/
i=a++ + ++a + ++a; /*a = 5;
i=a++ + ++a + ++a; =>
i=8 + 10 + 11; (a=11); i=29;*/
a=++a + ++a + a++; /*a=5;
a=++a + ++a + a++; =>
a=12 + 13 + 13; a=38;*/
System.out.println(a); //output: 38
System.out.println(i); //output: 29

We can use the Jackson library to convert a Java object into a Map easily.
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.6.3</version>
</dependency>
If using in an Android project, you can add jackson in your app's build.gradle as follows:
implementation 'com.fasterxml.jackson.core:jackson-core:2.9.8'
implementation 'com.fasterxml.jackson.core:jackson-annotations:2.9.8'
implementation 'com.fasterxml.jackson.core:jackson-databind:2.9.8'
Sample Implementation
public class Employee {
private String name;
private int id;
private List<String> skillSet;
// getters setters
}
public class ObjectToMap {
public static void main(String[] args) {
ObjectMapper objectMapper = new ObjectMapper();
Employee emp = new Employee();
emp.setName("XYZ");
emp.setId(1011);
emp.setSkillSet(Arrays.asList("python","java"));
// object -> Map
Map<String, Object> map = objectMapper.convertValue(emp,
Map.class);
System.out.println(map);
}
}
Output:
{name=XYZ, id=1011, skills=[python, java]}
My reason for researching this question was from the perspective, is in what way are they compatible. Latin1 charset (iso-8859) is 100% compatible to be stored in a utf8 datastore. All ascii & extended-ascii chars will be stored as single-byte.
Going the other way, from utf8 to Latin1 charset may or may not work. If there are any 2-byte chars (chars beyond extended-ascii 255) they will not store in a Latin1 datastore.
I came across this piece of code that uses Linq and regex to parse a CSV file. The refering article is now over a year and a half old, but have not come across a neater way to parse a CSV using Linq (and regex) than this. The caveat is the regex applied here is for comma delimited files (will detect commas inside quotes!) and that it may not take well to headers, but there is a way to overcome these). Take a peak:
Dim lines As String() = System.IO.File.ReadAllLines(strCustomerFile)
Dim pattern As String = ",(?=(?:[^""]*""[^""]*"")*(?![^""]*""))"
Dim r As System.Text.RegularExpressions.Regex = New System.Text.RegularExpressions.Regex(pattern)
Dim custs = From line In lines _
Let data = r.Split(line) _
Select New With {.custnmbr = data(0), _
.custname = data(1)}
For Each cust In custs
strCUSTNMBR = Replace(cust.custnmbr, Chr(34), "")
strCUSTNAME = Replace(cust.custname, Chr(34), "")

Well, there are plenty of database tutorials online for java (what you're looking for is called JDBC). But if you are using plain servlets, you will have a class that extends HttpServlet
and inside it you will have two methods that look like
public void doPost(HttpServletRequest req, HttpServletResponse resp){
}
and
public void doGet(HttpServletRequest req, HttpServletResponse resp){
}
One of them is called to handle GET
operations and another is used to handle POST
operations. You will then use the HttpServletRequest
object to get the parameters that were passed as part of the form like so:
String name = req.getParameter("name");
Then, once you have the data from the form, it's relatively easy to add it to a database using a JDBC tutorial that is widely available on the web. I also suggest searching for a basic Java servlet tutorial to get you started. It's very easy, although there are a number of steps that need to be configured correctly.
An easy way to do this is using the pandas
library like this.
import pandas as pd
fields = ['star_name', 'ra']
df = pd.read_csv('data.csv', skipinitialspace=True, usecols=fields)
# See the keys
print df.keys()
# See content in 'star_name'
print df.star_name
The problem here was the skipinitialspace
which remove the spaces in the header. So ' star_name' becomes 'star_name'
In Swift 2:
extension NSMutableURLRequest {
func setAuthorizationHeader(username username: String, password: String) -> Bool {
guard let data = "\(username):\(password)".dataUsingEncoding(NSUTF8StringEncoding) else { return false }
let base64 = data.base64EncodedStringWithOptions([])
setValue("Basic \(base64)", forHTTPHeaderField: "Authorization")
return true
}
}
The 2nd call to Enable-Migrations is failing because the Configuration.cs file already exists. If you rename that class and file, you should be able to run that 2nd Enable-Migrations, which will create another Configuration.cs.
You will then need to specify which configuration you want to use when updating the databases.
Update-Database -ConfigurationTypeName MyRenamedConfiguration
This is how to use chai to deeply test associative arrays.
I had an issue trying to assert that two associative arrays were equal. I know that these shouldn't really be used in javascript but I was writing unit tests around legacy code which returns a reference to an associative array. :-)
I did it by defining the variable as an object (not array) prior to my function call:
var myAssocArray = {}; // not []
var expectedAssocArray = {}; // not []
expectedAssocArray['myKey'] = 'something';
expectedAssocArray['differentKey'] = 'something else';
// legacy function which returns associate array reference
myFunction(myAssocArray);
assert.deepEqual(myAssocArray, expectedAssocArray,'compare two associative arrays');
Check out Oj. There are gotchas when it comes to converting any old object to JSON, but Oj can do it.
require 'oj'
class A
def initialize a=[1,2,3], b='hello'
@a = a
@b = b
end
end
a = A.new
puts Oj::dump a, :indent => 2
This outputs:
{
"^o":"A",
"a":[
1,
2,
3
],
"b":"hello"
}
Note that ^o
is used to designate the object's class, and is there to aid deserialization. To omit ^o
, use :compat
mode:
puts Oj::dump a, :indent => 2, :mode => :compat
Output:
{
"a":[
1,
2,
3
],
"b":"hello"
}
Here I propose a way to do this exclusively using the Bootstrap framework built-in functionality.
div
has an ID.class
"collapse", this will hide your block by
default. If you want your div to be collapsible AND be shown by
default you need to add "in" class to the collapse. Otherwise the
toggle behavior will not work properly.data-toggle="collapse"
to instruct
Bootstrap to add an appropriate toggle script to this tag.Here is a code sample than can be copy-pasted directly on a page that already includes Bootstrap framework (up to version 3.4.1):
<a href="#Foo" class="btn btn-default" data-toggle="collapse">Toggle Foo</a>
<button href="#Bar" class="btn btn-default" data-toggle="collapse">Toggle Bar</button>
<div id="Foo" class="collapse">
This div (Foo) is hidden by default
</div>
<div id="Bar" class="collapse in">
This div (Bar) is shown by default and can toggle
</div>
A boolean in SQL is a bit field. This means either 1 or 0. The correct syntax is:
select * from users where active = 1 /* All Active Users */
or
select * from users where active = 0 /* All Inactive Users */
req.headers.host.split(':')[1]
Honestly, I feel more comfortable with Alfred blog definitions:
Object: real world objects shares 2 main characteristics, state and behavior. Human have state (name, age) and behavior (running, sleeping). Car have state (current speed, current gear) and behavior (applying brake, changing gear). Software objects are conceptually similar to real-world objects: they too consist of state and related behavior. An object stores its state in fields and exposes its behavior through methods.
Class: is a “template” / “blueprint” that is used to create objects. Basically, a class will consists of field, static field, method, static method and constructor. Field is used to hold the state of the class (eg: name of Student object). Method is used to represent the behavior of the class (eg: how a Student object going to stand-up). Constructor is used to create a new Instance of the Class.
Instance: An instance is a unique copy of a Class that representing an Object. When a new instance of a class is created, the JVM will allocate a room of memory for that class instance.
Given the next example:
public class Person {
private int id;
private String name;
private int age;
public Person (int id, String name, int age) {
this.id = id;
this.name = name;
this.age = age;
}
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + id;
return result;
}
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Person other = (Person) obj;
if (id != other.id)
return false;
return true;
}
public static void main(String[] args) {
//case 1
Person p1 = new Person(1, "Carlos", 20);
Person p2 = new Person(1, "Carlos", 20);
//case 2
Person p3 = new Person(2, "John", 15);
Person p4 = new Person(3, "Mary", 17);
}
}
For case 1, there are two instances of the class Person, but both instances represent the same object.
For case 2, there are two instances of the class Person, but each instance represent a different object.
So class, object and instance are different things. Object and instance are not synonyms as is suggested in the answer selected as right answer.

Ok so I took Joshoun code and made it generic. I am not sure if I should implement singleton pattern on SynchronousPost class. Maybe someone more knowledgeble can help.

}
public void PostEntity(T PostThis,string ApiControllerName)//The ApiController name should be "/api/MyName/"
{
//this just determines the root url.

Create id column in your data frame or use any column name to identify the row. Using index is not fair to delete.
Use subset
function to create new frame.
updated_myData <- subset(myData, id!= 6)
print (updated_myData)
updated_myData <- subset(myData, id %in% c(1, 3, 5, 7))
print (updated_myData)
A simple function like below will help :
public string GetCurrentPageName()
{
string sPath = System.Web.HttpContext.Current.Request.Url.AbsolutePath;
System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath);
string sRet = oInfo.Name;
return sRet;
}
It depends on whether you are using JPA or Hibernate.
From the JPA 2.0 spec, the defaults are:
OneToMany: LAZY
ManyToOne: EAGER
ManyToMany: LAZY
OneToOne: EAGER
And in hibernate, all is Lazy
UPDATE:
The latest version of Hibernate aligns with the above JPA defaults.
In many cases you're better off using CSS transitions for this, and in old browsers the easing will simply be instant. Most animations (like fade in/out) are very trivial to implement and the browser does all the legwork for you. https://developer.mozilla.org/en/docs/Web/CSS/transition
mine was:
<youtube-player

I just removed the line with playerVars, and it worked without errors on console.
Why not use
$appended = array_merge($a,$b);
Why don't you want to use this, the correct, built-in method.
The problem is that IE does not have the standard addEventListener
method. IE uses its own attachEvent
which does pretty much the same.
Good explanation of the differences, and also about the 3rd parameter can be found at quirksmode.
To bring the existing answers together with an important clarification:
As stated, the problem with NAME=sam echo "$NAME"
is that $NAME
gets expanded by the current shell before assignment NAME=sam
takes effect.
Solutions that preserve the original semantics (of the (ineffective) solution attempt NAME=sam echo "$NAME"
):
Use either eval
[1]
(as in the question itself), or printenv
(as added by Aaron McDaid to heemayl's answer), or bash -c
(from Ljm Dullaart's answer), in descending order of efficiency:
NAME=sam eval 'echo "$NAME"' # use `eval` only if you fully control the command string
NAME=sam printenv NAME
NAME=sam bash -c 'echo "$NAME"'
printenv
is not a POSIX utility, but it is available on both Linux and macOS/BSD.
What this style of invocation (<var>=<name> cmd ...
) does is to define NAME
:
In other words: NAME
only exists for the command being invoked, and has no effect on the current shell (if no variable named NAME
existed before, there will be none after; a preexisting NAME
variable remains unchanged).
POSIX defines the rules for this kind of invocation in its Command Search and Execution chapter.
The following solutions work very differently (from heemayl's answer):
NAME=sam; echo "$NAME"
NAME=sam && echo "$NAME"
While they produce the same output, they instead define:
NAME
(only) rather than an environment variable
echo
were a command that relied on environment variable NAME
, it wouldn't be defined (or potentially defined differently from earlier).Note that every environment variable is also exposed as a shell variable, but the inverse is not true: shell variables are only visible to the current shell and its subshells, but not to child processes, such as external utilities and (non-sourced) scripts (unless they're marked as environment variables with export
or declare -x
).
[1] Technically, bash
is in violation of POSIX here (as is zsh
): Since eval
is a special shell built-in, the preceding NAME=sam
assignment should cause the the variable $NAME
to remain in scope after the command finishes, but that's not what happens.
However, when you run bash
in POSIX compatibility mode, it is compliant.
dash
and ksh
are always compliant.
The exact rules are complicated, and some aspects are left up to the implementations to decide; again, see Command Search and Execution.
Also, the usual disclaimer applies: Use eval
only on input you fully control or implicitly trust.
Simply the answer according to my reading and understanding to this thread and @remus-rusanu answer is based on this simple scenario:
There are two transactions A and B. Transaction B is reading Table X Transaction A is writing in table X Transaction B is reading again in Table X.

then
git push -u origin master
hope it works for you.

To split the string ({filepath}/{filename}) and get the file name you could use something like this:
str.split(/(\\|\/)/g).pop()
"The pop method removes the last element from an array and returns that value to the caller."
Mozilla Developer Network
Example:
from: "/home/user/file.txt".split(/(\\|\/)/g).pop()
you get: "file.txt"
In the nav go View => Layout => Columns:2
(alt+shift+2
) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py
)
It appears you can also reopen the file using the command File -> New View into File
which will open the current file in a new tab

Try adding a semi colon to the end of your structure:
struct sotrudnik {
string name;
string speciality;
string razread;
int zarplata;
} //Semi colon here
-u option will display including object files if they are added during compilation.
So, to overcome that additionally you may use like this.
svn status -u | grep -v '\?'
You can use Uber's H3,point_dist()
function to compute the spherical distance between two (lat, lng) points. We can set return unit ('km', 'm', or 'rads'). The default unit is Km.
Example :
import H3
coords_1 = (52.2296756, 21.0122287)
coords_2 = (52.406374, 16.9251681)
distance = h3.point_dist(coords_1,coords_2) #278.4584889328128
Hope this will usefull!
Or simply use
ng-show="v.hasOwnProperty('secId')"
See updated solution here:
I usually start with something like:
set lines 256
set trimout on
set tab off
Have a look at help set
if you have the help information installed. And then select name,address
rather than select *
if you really only want those two columns.
Define this function (say in ~/.bashrc):
time::clock() {
[ -z "$ts" ]&&{ ts=`date +%s%N`;return;}||te=`date +%s%N`
printf "%6.4f" $(echo $((te-ts))/1000000000 | bc -l)
unset ts te
}
Now you can measure time of parts of your scripts:
$ cat script.sh
# ... code ...
time::clock
sleep 0.5
echo "Total time: ${time::clock}"
# ... more code ...
$ ./script.sh
Total time: 0.5060
very useful to find execution bottlenecks.
Sometimes in similar situations (I don't think it is your problem because your case is very simple) it's worth to check kotlin file package.
If you have Kotlin file within the same package and put there some classes and missed the package declaration it looks inside the IntelliJ that you have classes in the same package but without definition of package the IntelliJ shows you:
Error:(5, 5) Kotlin: Unresolved reference: ...
These numbers come from the IEEE-754 standard, which defines the standard representation of floating point numbers. Wikipedia article at the link explains how to arrive at these ranges knowing the number of bits used for the signs, mantissa, and the exponent.
As of C++11, you have two major additional options. First, you can use insert()
with list initialization syntax:
function.insert({0, 42});
This is functionally equivalent to
function.insert(std::map<int, int>::value_type(0, 42));
but much more concise and readable. As other answers have noted, this has several advantages over the other forms:
operator[]
approach requires the mapped type to be assignable, which isn't always the case.operator[]
approach can overwrite existing elements, and gives you no way to tell whether this has happened.insert
that you list involve an implicit type conversion, which may slow your code down.The major drawback is that this form used to require the key and value to be copyable, so it wouldn't work with e.g. a map with unique_ptr
values. That has been fixed in the standard, but the fix may not have reached your standard library implementation yet.
Second, you can use the emplace()
method:
function.emplace(0, 42);
This is more concise than any of the forms of insert()
, works fine with move-only types like unique_ptr
, and theoretically may be slightly more efficient (although a decent compiler should optimize away the difference). The only major drawback is that it may surprise your readers a little, since emplace
methods aren't usually used that way.
This can happen for several reasons, including:

When you say you increased MAVEN_OPTS
, what values did you increase? Did you increase the MaxPermSize
, as in example:
export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=128m"
(or on Windows:)
set MAVEN_OPTS=-Xmx512m -XX:MaxPermSize=128m
You can also specify these JVM options in each maven project separately.
In drawable I use this xml code to define the border and background:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="4dp" android:color="#D8FDFB" />
<padding android:left="7dp" android:top="7dp"
android:right="7dp" android:bottom="7dp" />
<corners android:radius="4dp" />
<solid android:color="#f0600000"/>
</shape>
if it is becoming repetitive work ; i think you shud do code reuse ! why dont you simply write functions that "write" small building blocks of HTML. get the idea? see Eg. you can have a function to which you could pass a string and it would automatically put that into a paragraph tag and present it. Of course you would also need to write some kind of a basic parser to do this (how would the function know where to attach the paragraph!). i dont think you are a beginner .. so i am not elaborating ... do tell me if you do not understand..
This may not only happen due to windows containers!
Today all Node.Js docker images are not pullable. Always check the image you are trying to pull before.
document.getElementById("textareaID").value
$("#textareaID").val()
Cannot do the other way round (it's always good to know what you're doing)
document.getElementById("textareaID").value() // --> TypeError: Property 'value' of object #<HTMLTextAreaElement> is not a function
jQuery:
$("#textareaID").value // --> undefined
Working with Oracle, I was trying to insert a default value for an Enum
I found the following to work the best.
@Column(nullable = false)
@Enumerated(EnumType.STRING)
private EnumType myProperty = EnumType.DEFAULT_VALUE;
if you want a mysql solution, I had similar issues with 2 of my projects, after a server migration. After searching and trying a lot of solutions i came across with this one /nothing before this one worked):
mysqli_set_charset($con,"utf8");
After adding this line to my config file everything works fine!
I found this solution https://www.w3schools.com/PHP/func_mysqli_set_charset.asp when i was looking to solve a insert from html query
good luck!
In addition, gcc will look in the directories specified after the -I
option.
In case we want all the Person (instead of only one Person) in the returning dictionary, we could:
var _people = personList
.GroupBy(p => p.FirstandLastName)
.ToDictionary(g => g.Key, g => g.Select(x=>x));
xxx >& filename
Or do this to see everything on the screen and have it go to your file:
xxx | & tee ./logfile
from selenium import webdriver
from selenium.webdriver.common.proxy import *
myProxy = "86.111.144.194:3128"
proxy = Proxy({
'proxyType': ProxyType.MANUAL,
'httpProxy': myProxy,
'ftpProxy': myProxy,
'sslProxy': myProxy,
'noProxy':''})
driver = webdriver.Firefox(proxy=proxy)
driver.set_page_load_timeout(30)
driver.get('http://whatismyip.com')
df.replace('-', np.nan).astype("object")
This will ensure that you can use isnull()
later on your dataframe
You can use various options with FINDSTR to remove the lines do not want, like so:
DIR /S | FINDSTR "\-" | FINDSTR /VI DIR
Normal output contains entries like these:
28-Aug-14 05:14 PM <DIR> .
28-Aug-14 05:14 PM <DIR> ..
You could remove these using the various filtering options offered by FINDSTR. You can also use the excellent unxutils, but it converts the output to UNIX by default, so you no longer get CR+LF; FINDSTR offers the best Windows option.
No, it's not possible, as the styling for these elements is handled by the user's OS. MSDN will answer your question here:
Except for
background-color
andcolor
, style settings applied through the style object for the option element are ignored.
