Possibly something has changed in recent TensorFlow builds, because for me, running
sess = tf.Session()
sess.run(tf.local_variables_initializer())
before fitting any models seems to do the trick. Most older examples and comments seem to suggest tf.global_variables_initializer()
.
Interfaces can not contain any implementation (including default values). You need to switch to abstract class.
Change
vote = input('Enter the name of the player you wish to vote for')
to
vote = int(input('Enter the name of the player you wish to vote for'))
You are getting the input from the console as a string, so you must cast that input string to an int
object in order to do numerical operations.
Try this:
<script>
window.onbeforeunload = function (e) {
e = e || window.event;
// For IE and Firefox prior to version 4
if (e) {
e.returnValue = 'Sure?';
}
// For Safari
return 'Sure?';
};
</script>
Here is a working jsFiddle
nginx "fails fast" when the client informs it that it's going to send a body larger than the client_max_body_size
by sending a 413 response and closing the connection.
Most clients don't read responses until the entire request body is sent. Because nginx closes the connection, the client sends data to the closed socket, causing a TCP RST.
If your HTTP client supports it, the best way to handle this is to send an Expect: 100-Continue
header. Nginx supports this correctly as of 1.2.7, and will reply with a 413 Request Entity Too Large
response rather than 100 Continue
if Content-Length
exceeds the maximum body size.
It all depends what type of tag you want to create:
git tag -a v1.0.0
.git tag v1.0.0
.There are a few other tag functionalities such as:
git tag -l -n3
. The command lists all existing tags with maximum 3 lines of their tag message. By default -n only shows the first line.git show <tag_identifier>
. It shows all you need to know about a specific tag.git tag --sort=<type>
git push origin v1.0
. You can git push the tag individually, or you can run git push --tags which will push all tags at once. Be sure to check this tag related article for more relevant information.
Can the problem be with the "a.mProperty > b.mProperty" line? I've gotten the following code to work:
#include <algorithm>
#include <vector>
#include <iterator>
#include <iostream>
#include <sstream>
struct Foo
{
Foo() : _i(0) {};
int _i;
friend std::ostream& operator<<(std::ostream& os, const Foo& f)
{
os << f._i;
return os;
};
};
typedef std::vector<Foo> VectorT;
std::string toString(const VectorT& v)
{
std::stringstream ss;
std::copy(v.begin(), v.end(), std::ostream_iterator<Foo>(ss, ", "));
return ss.str();
};
int main()
{
VectorT v(10);
std::for_each(v.begin(), v.end(),
[](Foo& f)
{
f._i = rand() % 100;
});
std::cout << "before sort: " << toString(v) << "\n";
sort(v.begin(), v.end(),
[](const Foo& a, const Foo& b)
{
return a._i > b._i;
});
std::cout << "after sort: " << toString(v) << "\n";
return 1;
};
The output is:
before sort: 83, 86, 77, 15, 93, 35, 86, 92, 49, 21,
after sort: 93, 92, 86, 86, 83, 77, 49, 35, 21, 15,
You say you "really just want B", but this is false. You want B, but you also want an updated A if there have been any changes to it ("active development").
So, sometimes you want to work with A, B, and C. For this case you have aggregator project P. For the case where you want to work with A and B (but do not want C), you should create aggregator project Q.
Edit 2016: The above information was perhaps relevant in 2009. As of 2016, I highly recommend ignoring this in most cases, and simply using the -am
or -pl
command-line flags as described in the accepted answer. If you're using a version of maven from before v2.1, change that first :)
This is not possible from javascript, because this is a server-side property. Javascript on the client cannot know where joomla is installed. The best option is to somehow include the value of $this->baseurl
into the page javascript and then use this value (phpBaseUrl
).
You can then build the url like this:
var loc = window.location;
var baseUrl = loc.protocol + "//" + loc.hostname + (loc.port? ":"+loc.port : "") + "/" + phpBaseUrl;
It happens that /etc/hosts
file doesn't support wild card entries.
You'll have to use other services like dnsmasq. To enable it in dnsmasq, just edit dnsmasq.conf
and add the following line:
address=/example.com/127.0.0.1
Make sure you have added your device - https://developer.apple.com/account/ios/device/create
Go into iTunes and click on the serial number and it'll change to the UDID - then right click to Copy the UDID and register it as your device.
You can then add that device to your provisioning profile.
This code can do the trick as well, using the SCSS syntax
.parent {
& > * {
margin-right: 15px;
&:last-child {
margin-right: 0;
}
}
}
Try this
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
alert('123');
});
$('#ancherComplaint').click(function (event) {
alert($(this).attr("id"));
event.stopPropagation()
})
Encoding flash video is actually very easy with ffmpeg. You can use one command to convert from just about any video format, ffmpeg is smart enough to figure the rest out, and it'll use every processor on your machine. Invoking it is easy:
ffmpeg -i input.avi output.flv
ffmpeg will guess at the bitrate you want, but if you'd like to specify one, you can use the -b option, so -b 500000
is 500kbps for example. There's a ton of options of course, but I generally get good results without much tinkering. This is a good place to start if you're looking for more options: video options.
You don't need a special web server to show flash video. I've done just fine by simply pushing .flv files up to a standard web server, and linking to them with a good swf player, like flowplayer.
WMVs are fine if you can be sure that all of your users will always use [a recent, up to date version of] Windows only, but even then, Flash is often a better fit for the web. The player is even extremely skinnable and can be controlled with javascript.
Try this to get the month in number form:
Month(DateAdd("m", -3, Now))
It will give you 12
for December.
So in your case you would use Month(DateAdd("m", -1, Now))
to just subract one month.
Add this script element to your body element, changing the color as desired:
<body>_x000D_
<p>Hello, World!</p>_x000D_
<script type="text/javascript">_x000D_
document.body.style.backgroundColor = "#ff0000"; // red_x000D_
</script>_x000D_
</body>
_x000D_
I like @jesterjunk answer, however, a number is not always just digits. Consider those valid numbers: "123.5, 123,567.789, 12233234+E12"
So I just updated the regular expression:
var regex = /[\d|,|.|e|E|\+]+/g;
var string = "you can enter maximum 5,123.6 choices";
var matches = string.match(regex); // creates array from matches
document.write(matches); //5,123.6
Though the question is old enough it still can be referenced nowdays.
Semantically that is exactly what Java 12 introduced (https://openjdk.java.net/jeps/325), thus, exactly in that simple example provided I can't see any problem or cons.
Here's my twist on it, with a runnable example. Note this will only work in the situation where Id
is unique, and you have duplicate values in other columns.
DECLARE @SampleData AS TABLE (Id int, Duplicate varchar(20))
INSERT INTO @SampleData
SELECT 1, 'ABC' UNION ALL
SELECT 2, 'ABC' UNION ALL
SELECT 3, 'LMN' UNION ALL
SELECT 4, 'XYZ' UNION ALL
SELECT 5, 'XYZ'
DELETE FROM @SampleData WHERE Id IN (
SELECT Id FROM (
SELECT
Id
,ROW_NUMBER() OVER (PARTITION BY [Duplicate] ORDER BY Id) AS [ItemNumber]
-- Change the partition columns to include the ones that make the row distinct
FROM
@SampleData
) a WHERE ItemNumber > 1 -- Keep only the first unique item
)
SELECT * FROM @SampleData
And the results:
Id Duplicate
----------- ---------
1 ABC
3 LMN
4 XYZ
Not sure why that's what I thought of first... definitely not the simplest way to go but it works.
Numerous other answers have more than covered how you can do this but why you probably should not in normal circumstances. That said, I will add why I've done it in the past.
In embedded development, it's common to have silicon vendor source code as part of your compiled files. The problem is those vendors likely don't have the same style guides or standard warning/error flag settings as your organization.
So, you can create a local source file that includes the vendor source code and then compile this wrapper C file instead to suppress any issues in the included source as well as any headers included by that source. As an example:
/**
* @file vendor_wrap.c
* @brief vendor source code wrapper to prevent warnings
*/
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wnested-externs"
#include "vendor_source_code.c"
#pragma GCC diagnostic pop
This allows you to use less complicated Make scripting with a standard set of compiler flags and settings with specific exceptions in the code rather than have custom flags for some files in the scripting.
gcc main.c vendor_wrap.c -o $(CFLAGS) main.out
From version 9.1.4 you only need to import ReactiveFormsModule
I had exact same problem, tried all of the suggestions but got nothing. Bugged me hours. Turned out my ISP blocked port 80 for some reasons.
Advice: check your traffic. Make sure port 80 works both locally (i.e. firewall) and externally.
There might be a better way but here is what I have done in the past and it works quite well:
items = data.items() #Gets all the data from this Bunch - a huge list
mydata = pd.DataFrame(items[1][1]) #Gets the Attributes
mydata[len(mydata.columns)] = items[2][1] #Adds a column for the Target Variable
mydata.columns = items[-1][1] + [items[2][0]] #Gets the column names and updates the dataframe
Now mydata will have everything you need - attributes, target variable and columnnames
@selectField1 AS bit
@selectField2 AS bit
SELECT
CASE
WHEN @selectField1 THEN Field1
WHEN @selectField2 THEN Field2
ELSE someDefaultField
END
FROM Table
Is this what you're looking for?
The "no frills" options are as follows:
ActiveSheet.Name = "New Name"
and
Sheets("Sheet2").Name = "New Name"
You can also check out recording macros and seeing what code it gives you, it's a great way to start learning some of the more vanilla functions.
I do not think there is a definitive right answer to your question. Instead there is a big bundle of ways how to get close to what you wish. Hence I will provide some hints how to get it done.
If a machine has more than 2 interfaces (lo
counts as one) you will have problems to autodetect the right interface easily. Here are some recipes on how to do it.
The problem, for example, is if hosts are in a DMZ behind a NAT firewall which changes the public IP into some private IP and forwards the requests. Your machine may have 10 interfaces, but only one corresponds to the public one.
Even autodetection does not work in case you are on double-NAT, where your firewall even translates the source-IP into something completely different. So you cannot even be sure, that the default route leads to your interface with a public interface.
This is my recommended way to autodetect things
Something like ip r get 1.1.1.1
usually tells you the interface which has the default route.
If you want to recreate this in your favourite scripting/programming language, use strace ip r get 1.1.1.1
and follow the yellow brick road.
/etc/hosts
This is my recommendation if you want to stay in control
You can create an entry in /etc/hosts
like
80.190.1.3 publicinterfaceip
Then you can use this alias publicinterfaceip
to refer to your public interface.
Sadly
haproxy
does not grok this trick with IPv6
This is a good workaround for
/etc/hosts
in case you are notroot
Same as /etc/hosts
. but use the environment for this. You can try /etc/profile
or ~/.profile
for this.
Hence if your program needs a variable MYPUBLICIP
then you can include code like (this is C, feel free to create C++ from it):
#define MYPUBLICIPENVVAR "MYPUBLICIP"
const char *mypublicip = getenv(MYPUBLICIPENVVAR);
if (!mypublicip) { fprintf(stderr, "please set environment variable %s\n", MYPUBLICIPENVVAR); exit(3); }
So you can call your script/program /path/to/your/script
like this
MYPUBLICIP=80.190.1.3 /path/to/your/script
this even works in crontab
.
The desperate way if you cannot use
ip
If you do know what you do not want, you can enumerate all interfaces and ignore all the false ones.
Here already seems to be an answer https://stackoverflow.com/a/265978/490291 for this approach.
The way of the drunken man who tries to drown himself in alcohol
You can try to enumerate all the UPnP gateways on your network and this way find out a proper route for some "external" thing. This even might be on a route where your default route does not point to.
For more on this perhaps see https://en.wikipedia.org/wiki/Internet_Gateway_Device_Protocol
This gives you a good impression which one is your real public interface, even if your default route points elsewhere.
Where the mountain meets the prophet
IPv6 routers advertise themselves to give you the right IPv6 prefix. Looking at the prefix gives you a hint about if it has some internal IP or a global one.
You can listen for IGMP or IBGP frames to find out some suitable gateway.
There are less than 2^32 IP addresses. Hence it does not take long on a LAN to just ping them all. This gives you a statistical hint on where the majority of the Internet is located from your point of view. However you should be a bit more sensible than the famous https://de.wikipedia.org/wiki/SQL_Slammer
ICMP and even ARP are good sources for network sideband information. It might help you out as well.
You can use Ethernet Broadcast address to contact to all your network infrastructure devices which often will help out, like DHCP (even DHCPv6) and so on.
This additional list is probably endless and always incomplete, because every manufacturer of network devices is busily inventing new security holes on how to auto-detect their own devices. Which often helps a lot on how to detect some public interface where there shouln't be one.
'Nuff said. Out.
You can do Response.redirect("YourPage",false)
that will refresh your page and also increase counter.
I'm using a support widget Toolbar v7. So, in order to be able to delete or hide the Title we need to write this.
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
//Remove¡ing title bar
getSupportActionBar().setDisplayShowTitleEnabled(false);
I would like to share a detailed way of how to post with PHP + Ajax along with errors thrown back on failure.
First of all, create two files, for example form.php
and process.php
.
We will first create a form
which will be then submitted using the jQuery
.ajax()
method. The rest will be explained in the comments.
form.php
<form method="post" name="postForm">
<ul>
<li>
<label>Name</label>
<input type="text" name="name" id="name" placeholder="Bruce Wayne">
<span class="throw_error"></span>
<span id="success"></span>
</li>
</ul>
<input type="submit" value="Send" />
</form>
Validate the form using jQuery client-side validation and pass the data to process.php
.
$(document).ready(function() {
$('form').submit(function(event) { //Trigger on form submit
$('#name + .throw_error').empty(); //Clear the messages first
$('#success').empty();
//Validate fields if required using jQuery
var postForm = { //Fetch form data
'name' : $('input[name=name]').val() //Store name fields value
};
$.ajax({ //Process the form using $.ajax()
type : 'POST', //Method type
url : 'process.php', //Your form processing file URL
data : postForm, //Forms name
dataType : 'json',
success : function(data) {
if (!data.success) { //If fails
if (data.errors.name) { //Returned if any error from process.php
$('.throw_error').fadeIn(1000).html(data.errors.name); //Throw relevant error
}
}
else {
$('#success').fadeIn(1000).append('<p>' + data.posted + '</p>'); //If successful, than throw a success message
}
}
});
event.preventDefault(); //Prevent the default submit
});
});
Now we will take a look at process.php
$errors = array(); //To store errors
$form_data = array(); //Pass back the data to `form.php`
/* Validate the form on the server side */
if (empty($_POST['name'])) { //Name cannot be empty
$errors['name'] = 'Name cannot be blank';
}
if (!empty($errors)) { //If errors in validation
$form_data['success'] = false;
$form_data['errors'] = $errors;
}
else { //If not, process the form, and return true on success
$form_data['success'] = true;
$form_data['posted'] = 'Data Was Posted Successfully';
}
//Return the data back to form.php
echo json_encode($form_data);
The project files can be downloaded from http://projects.decodingweb.com/simple_ajax_form.zip.
Alternatively, if using javax.net.ssl.trustStore for specifying the location of your truststore does not work ( as it did in my case for two way authentication ), you can also use SSLContextBuilder as shown in the example below. This example also includes how to create a httpclient as well to show how the SSL builder would work.
SSLContextBuilder sslcontextbuilder = SSLContexts.custom();
sslcontextbuilder.loadTrustMaterial(
new File("C:\\path to\\truststore.jks"), //path to jks file
"password".toCharArray(), //enters in the truststore password for use
new TrustSelfSignedStrategy() //will trust own CA and all self-signed certs
);
SSLContext sslcontext = sslcontextbuilder.build(); //load trust store
SSLConnectionSocketFactory sslsockfac = new SSLConnectionSocketFactory(sslcontext,new String[] { "TLSv1" },null,SSLConnectionSocketFactory.getDefaultHostnameVerifier());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsockfac).build(); //sets up a httpclient for use with ssl socket factory
try {
HttpGet httpget = new HttpGet("https://localhost:8443"); //I had a tomcat server running on localhost which required the client to have their trust cert
System.out.println("Executing request " + httpget.getRequestLine());
CloseableHttpResponse response = httpclient.execute(httpget);
try {
HttpEntity entity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
EntityUtils.consume(entity);
} finally {
response.close();
}
} finally {
httpclient.close();
}
if you're using jQuery you would have:
$('#elementId').change(function() { alert('Do Stuff'); });
or MS AJAX:
$addHandler($get('elementId'), 'change', function(){ alert('Do Stuff'); });
Or in the raw HTML of the element:
<input type="text" onchange="alert('Do Stuff');" id="myElement" />
After re-reading the question I think I miss-read what was to be done. I've never found a way to update a DOM element in a manner which will force a change event, what you're best doing is having a separate event handler method, like this:
$addHandler($get('elementId'), 'change', elementChanged);
function elementChanged(){
alert('Do Stuff!');
}
function editElement(){
var el = $get('elementId');
el.value = 'something new';
elementChanged();
}
Since you're already writing a JavaScript method which will do the changing it's only 1 additional line to call.
Or, if you are using the Microsoft AJAX framework you can access all the event handlers via:
$get('elementId')._events
It'd allow you to do some reflection-style workings to find the right event handler(s) to fire.
In Laravel 5.5
Working on a similar issue and setting the middleware argument from guest to 'auth' seemed like a more elegant solution.
Edit File: app->http->Controllers->Auth->RegisterController.php
public function __construct()
{
//replace this
//$this->middleware('guest');
//with this argument.
$this->middleware('auth');
}
I could be wrong though...but it seems more slick than editing the routing with more lines and less shity than simply redirecting the page...at least in this instance, wanting to lock down the registration for guests.
In short set cascade type to all , will do a job; For an example in your model. Add Code like this . @OneToMany(mappedBy = "receipt", cascade=CascadeType.ALL) private List saleSet;
Try to place the code of your query before. That fix my problem. e.g. change this:
query1
query2 - get the error
update
to this:
query2
query1
update

currently pagavcs seems to be the best option.
you want one of these .deb
files
sillyspamfilter://pagavcs.googlecode.com/svn/repo/pool/main/p/pagavcs/
(1.4.33 is what I have installed right now so try that one if the latest causes problems)
install then run
nautilus -q
to shutdown nautilus, then open up nautilus again and you should be good to go without having to logout/shutdown
Sadly rabbit just chokes on large repos for me so is unusable, paga doesn't slow down browsing but also doesn't seem to try and recourse into directories to see if anything has changed.
In case you want to see the local variables of a calling function use select-frame
before info locals
E.g.:
(gdb) bt
#0 0xfec3c0b5 in _lwp_kill () from /lib/libc.so.1
#1 0xfec36f39 in thr_kill () from /lib/libc.so.1
#2 0xfebe3603 in raise () from /lib/libc.so.1
#3 0xfebc2961 in abort () from /lib/libc.so.1
#4 0xfebc2bef in _assert_c99 () from /lib/libc.so.1
#5 0x08053260 in main (argc=1, argv=0x8047958) at ber.c:480
(gdb) info locals
No symbol table info available.
(gdb) select-frame 5
(gdb) info locals
i = 28
(gdb)
There is an appropriate index on column_having_index, and its use actually increase performance, but Oracle didn't use it...
You should gather statistics on your table to let optimizer see that index access can help. Using direct hint is not a good practice.
Use the source
command.
source
For example:
#!/usr/bin/env bash
production="liveschool_joe"
playschool="playschool_joe"
echo $playschool
#!/usr/bin/env bash
source config.sh
echo $production
Note that the output from sh ./script.sh
in this example is:
~$ sh ./script.sh
playschool_joe
liveschool_joe
This is because the source
command actually runs the program. Everything in config.sh
is executed.
You could use the built-in export
command and getting and setting "environment variables" can also accomplish this.
Running export
and echo $ENV
should be all you need to know about accessing variables. Accessing environment variables is done the same way as a local variable.
To set them, say:
export variable=value
at the command line. All scripts will be able to access this value.
It will already work, as David pointed out!
>>> def machineEpsilon(func=float):
... machine_epsilon = func(1)
... while func(1)+func(machine_epsilon) != func(1):
... machine_epsilon_last = machine_epsilon
... machine_epsilon = func(machine_epsilon) / func(2)
... return machine_epsilon_last
...
>>> machineEpsilon(float)
2.220446049250313e-16
>>> import numpy
>>> machineEpsilon(numpy.float64)
2.2204460492503131e-16
>>> machineEpsilon(numpy.float32)
1.1920929e-07
I also encountered this problem in my project. It eventually worked after I inserted the my-controller.js
into my karma.conf.js
file, with the <script>
tag.
Hope this will help. There are quite many reasons that can lead to this problem.

Similar to another answer here, but change the http in the rewrite to to $scheme like so:
server {
listen 80;
server_name test.com;
rewrite ^ $scheme://www.test.com$request_uri? permanent;
}
And edit your main server block server_name variable as following:
server_name www.test.com;
I had to do this to redirect www.test.com to test.com.
The solution only solves part of the problem, it may let you style the container and contents but doesn't let you change the titlebar. I developed a workaround of sorts but adding an id to the dialog div, then using jQuery .prev to change the style of the div which is the previous sibling of the dialog's div. This works because when jQueryUI creates the dialog, your original div becomes a sibling of the new container, but the title div is a the immediately previous sibling to your original div but neither the container not the title div has an id to simplify selecting the div.
HTML
<button id="dialog1" class="btn btn-danger">Warning</button>
<div title="Nothing here, really" id="nonmodal1">
Nothing here
</div>
You can use CSS to style the main section of the dialog but not the title
.custom-ui-widget-header-warning {
background: #EBCCCC;
font-size: 1em;
}
You need some JS to style the title
$(function() {
$("#nonmodal1").dialog({
minWidth: 400,
minHeight: 'auto',
autoOpen: false,
dialogClass: 'custom-ui-widget-header-warning',
position: {
my: 'center',
at: 'left'
}
});
$("#dialog1").click(function() {
if ($("#nonmodal1").dialog("isOpen") === true) {
$("#nonmodal1").dialog("close");
} else {
$("#nonmodal1").dialog("open").prev().css('background','#D9534F');
}
});
});
The example only shows simple styling (background) but you can make it as complex as you wish.
You can see it in action here:
Without a nicer solution, what I found to work is simply building my query string in the bean return:
public String submit() {
// Do something
return "/page2.xhtml?faces-redirect=true&id=" + id;
}
Not the most flexible of solutions, but seems to work how I want it to.
Also using this approach to clean up the process of building the query string: http://www.warski.org/blog/?p=185
Try using if tracked file.
git rm <path to file>

echo stream_get_contents(fopen('http://example.com/', "rb")); //you may use "r" instead of "rb" //needs "Allow_url_fopen" enabled
?>
2) Better Way is CURL:
echo get_remote_data('http://example.com'); // GET request
echo get_remote_data('http://example.com', "var2=something&var3=blabla" ); // POST request
It automatically handles FOLLOWLOCATION problem + Remote urls:
src="./imageblabla.png"
turned into:src="http://example.com/path/imageblabla.png"

Bit of a late response but I noticed that this information can be hard to find and haven't found the answer on SO, so here it is.
Try a differnt parameter #view=FitH to force it to fit in the horzontal space and also you need to start the querystring off with a # rather than an & making it:
filename.pdf#view=FitH
What I've noticed it is that this will work if adobe reader is embedded in the browser but chrome will use it's own version of the reader and won't respond in the same way. In my own case, the chrome browser zoomed to fit width by default, so no problem , but Internet Explorer needed the above parameters to ensure the link always opened the pdf page with the correct view setting.
For a full list of available parameters see this doc

Look in the manual http://www.php.net/manual/en/mysqli.query.php

When using PDO for a database interacttion, one can use the PDO::FETCH_NAMED fetch mode that could help to resolve the issue:
$sql = "SELECT * FROM news JOIN users ON news.user = user.id";
$data = $pdo->query($sql)->fetchAll(PDO::FETCH_NAMED);
foreach ($data as $row) {
echo $row['column-name'][0]; // from the news table
echo $row['column-name'][1]; // from the users table
echo $row['other-column']; // any unique column name
}
I think its a bug, please apply the workaround and then try again: http://support.microsoft.com/kb/281517.
Also, go into Advanced tab, and confirm if Target columns length is Varchar(max).
If you consider the following:
os.path.isdir('/tmp/dirname')
means a directory (path) exists AND is a directory. So for me this way does what I need. So I can make sure it is folder (not a file) and exists.
Add to .bashrc
function ListAllCommands
{
echo -n $PATH | xargs -d : -I {} find {} -maxdepth 1 \
-executable -type f -printf '%P\n' | sort -u
}
If you also want aliases, then:
function ListAllCommands
{
COMMANDS=`echo -n $PATH | xargs -d : -I {} find {} -maxdepth 1 \
-executable -type f -printf '%P\n'`
ALIASES=`alias | cut -d '=' -f 1`
echo "$COMMANDS"$'\n'"$ALIASES" | sort -u
}
I spent 8 hours to do that. It is simple...
You shoud have a code like that:
private const int GENERIC_WRITE = 0x40000000;
//private const int OPEN_EXISTING = 3;
private const int OPEN_EXISTING = 1;
private const int FILE_SHARE_WRITE = 0x2;
private StreamWriter _fileWriter;
private FileStream _outFile;
private int _hPort;
Change that variable content from 3 (open file already exist) to 1 (create a new file). It'll work at Windows 7 and XP.
use git revert https://git-scm.com/docs/git-revert .It will revert all code then you can do next commit.Then head will point to that last commit. reverted commits never delete but it will not affect on you last commit.
You mentioned getting the result list from the Query, since you don't know that there is a UniqueResult (hence the exception) you could use list and check the size?
if (query.list().size() == 1)
Since you're not doing a get() to get your unique object a query will be executed whether you call uniqueResult or list.
Use this server variable to get the protocol details:
$scheme = $_SERVER['REQUEST_SCHEME'] . '://';
echo $scheme; //it gives http:// or https://
Note that this server variable is unreliable. For more information take a look at: Is $_SERVER['REQUEST_SCHEME'] reliable?
For reading/writing excel files, you can use :
readxl
package for reading and writexl
package for writingopenxlsx
package for reading and writingWith xlsx
and XLConnect
(which use rjava) you will face memory errors if you have large files
Python dictionaries have a key and a value, what you are asking for is what key(s) point to a given value.
You can only do this in a loop:
[k for (k, v) in i.iteritems() if v == 0]
Note that there can be more than one key per value in a dict; {'a': 0, 'b': 0}
is perfectly legal.
If you want ordering you either need to use a list or a OrderedDict instance instead:
items = ['a', 'b', 'c']
items.index('a') # gives 0
items[0] # gives 'a'
my_var = (int)my_var;
As simple as that. Basically you don't need it if the variable is int.
Random r = new Random();
int i1 = r.nextInt(80 - 65) + 65;
This gives a random integer between 65 (inclusive) and 80 (exclusive), one of 65,66,...,78,79
.
I've seen this anti-pattern from people who don't quite get the & address-of operator. If they need to call a function with a pointer, they'll always allocate on the heap so they get a pointer.
void FeedTheDog(Dog* hungryDog);
Dog* badDog = new Dog;
FeedTheDog(badDog);
delete badDog;
Dog goodDog;

Create a XIB file :
File -> new File ->ios->cocoa touch class -> next
make sure check mark "also create XIB file"
I would like to perform with tableview
so I choosed subclass UITableViewCell
you can choose as your requerment
XIB file desing as your wish (RestaurantTableViewCell.xib)
we need to grab the row height to set table each row hegiht
Now! need to huck them swift file . i am hucked the restaurantPhoto
and restaurantName
you can huck all of you .
Now adding a UITableView
name
The name of the nib file, which need not include the .nib extension.
owner
The object to assign as the nib’s File's Owner object.
options
A dictionary containing the options to use when opening the nib file.
first
if you do not define first then grabing all view .. so you need to grab one view inside that set frist
.
Bundle.main.loadNibNamed("yourUIView", owner: self, options: nil)?.first as! yourUIView
here is table view controller Full code
import UIKit
class RestaurantTableViewController: UIViewController ,UITableViewDataSource,UITableViewDelegate{
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 5
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let restaurantTableviewCell = Bundle.main.loadNibNamed("RestaurantTableViewCell", owner: self, options: nil)?.first as! RestaurantTableViewCell
restaurantTableviewCell.restaurantPhoto.image = UIImage(named: "image1")
restaurantTableviewCell.restaurantName.text = "KFC Chicken"
return restaurantTableviewCell
}
// set row height
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 150
}
}
you done :)
You can control the default behavior by setting push.default in your git config. From the git-config(1) documentation:
push.default
Defines the action git push should take if no refspec is given on the command line, no refspec is configured in the remote, and no refspec is implied by any of the options given on the command line. Possible values are:
nothing
: do not push anything
matching
: push all matching branches
All branches having the same name in both ends are considered to be matching.
This used to be the default, but not since Git 2.0 (simple
is the new default).
upstream
: push the current branch to its upstream branch (tracking
is a deprecated synonym for upstream)
current
: push the current branch to a branch of the same name
simple
: (new in Git 1.7.11) like upstream, but refuses to push if the upstream branch's name is different from the local one
This is the safest option and is well-suited for beginners.
This mode has become the default in Git 2.0.
The simple, current and upstream modes are for those who want to push out a single branch after finishing work, even when the other branches are not yet ready to be pushed out
Command line examples:
To view the current configuration:
git config --global push.default
To set a new configuration:
git config --global push.default current
Lambda can be any function. So if you had a function
def compare_person(a):
return a.age
You could sort a list of Person (each of which having an age attribute) like this:
sorted(personArray, key=compare_person)
This way, the list would be sorted by age in ascending order.
The parameter is called lambda because python has a nifty lambda keywords for defining such functions on the fly. Instead of defining a function compare_person and passing that to sorted, you can also write:
sorted(personArray, key=lambda a: a.age)
which does the same thing.
var_dump(extension_loaded('curl'));
If table cols and values are variables then there are two ways:
With double quotes ""
the complete query:
$query = "INSERT INTO $table_name (id, $col1, $col2)
VALUES (NULL, '$val1', '$val2')";
Or
$query = "INSERT INTO ".$table_name." (id, ".$col1.", ".$col2.")
VALUES (NULL, '".$val1."', '".$val2."')";
With single quotes ''
:
$query = 'INSERT INTO '.$table_name.' (id, '.$col1.', '.$col2.')
VALUES (NULL, '.$val1.', '.$val2.')';
Use back ticks ``
when a column/value name is similar to a MySQL reserved keyword.
Note: If you are denoting a column name with a table name then use back ticks like this:
`table_name`
. `column_name`
<-- Note: exclude .
from back ticks.
The error happens because of you are trying to map a numeric vector to data
in geom_errorbar
: GVW[1:64,3]
. ggplot
only works with data.frame
.
In general, you shouldn't subset inside ggplot
calls. You are doing so because your standard errors are stored in four separate objects. Add them to your original data.frame
and you will be able to plot everything in one call.
Here with a dplyr
solution to summarise the data and compute the standard error beforehand.
library(dplyr)
d <- GVW %>% group_by(Genotype,variable) %>%
summarise(mean = mean(value),se = sd(value) / sqrt(n()))
ggplot(d, aes(x = variable, y = mean, fill = Genotype)) +
geom_bar(position = position_dodge(), stat = "identity",
colour="black", size=.3) +
geom_errorbar(aes(ymin = mean - se, ymax = mean + se),
size=.3, width=.2, position=position_dodge(.9)) +
xlab("Time") +
ylab("Weight [g]") +
scale_fill_hue(name = "Genotype", breaks = c("KO", "WT"),
labels = c("Knock-out", "Wild type")) +
ggtitle("Effect of genotype on weight-gain") +
scale_y_continuous(breaks = 0:20*4) +
theme_bw()
In case you want to compare strings, write the following JSTL:
<c:choose>
<c:when test="${myvar.equals('foo')}">
...
</c:when>
<c:when test="${myvar.equals('bar')}">
...
</c:when>
<c:otherwise>
...
</c:otherwise>
</c:choose>
Can you clarify your question? What is "ohHover" in this case and how does it correspond to a delay in hover time?
That said, I think what you probably want is...
var timeout;
element.onmouseover = function(e) {
timeout = setTimeout(function() {
// ...
}, delayTimeMs)
};
element.onmouseout = function(e) {
if(timeout) {
clearTimeout(timeout);
}
};
Or addEventListener
/attachEvent
or your favorite library's event abstraction method.
I assume this code has concurrency issues:
Actually, it's quite possibly fine, though with a possible improvement.
Now, in general the pattern where we have multiple threads setting a shared value on first use, to not lock on the value being obtained and set can be:
However, considering here that MemoryCache
may evict entries then:
MemoryCache
is the wrong approach.MemoryCache
is thread-safe in terms of access to that object, so that is not a concern here.Both of these possibilities have to be thought about of course, though the only time having two instances of the same string existing can be a problem is if you're doing very particular optimisations that don't apply here*.
So, we're left with the possibilities:
SomeHeavyAndExpensiveCalculation()
.SomeHeavyAndExpensiveCalculation()
.And working that out can be difficult (indeed, the sort of thing where it's worth profiling rather than assuming you can work it out). It's worth considering here though that most obvious ways of locking on insert will prevent all additions to the cache, including those that are unrelated.
This means that if we had 50 threads trying to set 50 different values, then we'll have to make all 50 threads wait on each other, even though they weren't even going to do the same calculation.
As such, you're probably better off with the code you have, than with code that avoids the race-condition, and if the race-condition is a problem, you quite likely either need to handle that somewhere else, or need a different caching strategy than one that expels old entries†.
The one thing I would change is I'd replace the call to Set()
with one to AddOrGetExisting()
. From the above it should be clear that it probably isn't necessary, but it would allow the newly obtained item to be collected, reducing overall memory use and allowing a higher ratio of low generation to high generation collections.
So yeah, you could use double-locking to prevent concurrency, but either the concurrency isn't actually a problem, or your storing the values in the wrong way, or double-locking on the store would not be the best way to solve it.
*If you know only one each of a set of strings exists, you can optimise equality comparisons, which is about the only time having two copies of a string can be incorrect rather than just sub-optimal, but you'd want to be doing very different types of caching for that to make sense. E.g. the sort XmlReader
does internally.
†Quite likely either one that stores indefinitely, or one that makes use of weak references so it will only expel entries if there are no existing uses.

I've found that the jQuery Calendar plugin, for me at least, in general just works better for selecting dates.
I was looking for an easier-to-read time-loop when I encountered this question here. Something like:
for sec in max_seconds(10):
do_something()
So I created this helper:
# allow easy time-boxing: 'for sec in max_seconds(42): do_something()'
def max_seconds(max_seconds, *, interval=1):
interval = int(interval)
start_time = time.time()
end_time = start_time + max_seconds
yield 0
while time.time() < end_time:
if interval > 0:
next_time = start_time
while next_time < time.time():
next_time += interval
time.sleep(int(round(next_time - time.time())))
yield int(round(time.time() - start_time))
if int(round(time.time() + interval)) > int(round(end_time)):
return
It only works with full seconds which was OK for my use-case.
Examples:
for sec in max_seconds(10) # -> 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
for sec in max_seconds(10, interval=3) # -> 0, 3, 6, 9
for sec in max_seconds(7): sleep(1.5) # -> 0, 2, 4, 6
for sec in max_seconds(8): sleep(1.5) # -> 0, 2, 4, 6, 8
Be aware that interval isn't that accurate, as I only wait full seconds (sleep never was any good for me with times < 1 sec). So if your job takes 500 ms and you ask for an interval of 1 sec, you'll get called at: 0, 500ms, 2000ms, 2500ms, 4000ms and so on. One could fix this by measuring time in a loop rather than sleep() ...
All the above not working for me.. Because I am using Facebook Ad dependency..

For someone who needs quick reference of C# Escape Sequences that can be used in string
literals:
\t Horizontal tab (ASCII code value: 9)
\n Line feed (ASCII code value: 10)
\r Carriage return (ASCII code value: 13)
\' Single quotation mark
\" Double quotation mark
\\ Backslash
\? Literal question mark
\x12 ASCII character in hexadecimal notation (e.g. for 0x12)
\x1234 Unicode character in hexadecimal notation (e.g. for 0x1234)
It's worth mentioning that these (in most cases) are universal codes. So \t is 9 and \n is 10 char value on Windows and Linux. But newline sequence is not universal. On Windows it's \n\r and on Linux it's just \n. That's why it's best to use Environment.Newline
which gets adjusted to current OS settings. With .Net Core it gets really important.
Try this test:
any(substring in string for substring in substring_list)
It will return True
if any of the substrings in substring_list
is contained in string
.
Note that there is a Python analogue of Marc Gravell's answer in the linked question:
from itertools import imap
any(imap(string.__contains__, substring_list))
In Python 3, you can use map
directly instead:
any(map(string.__contains__, substring_list))
Probably the above version using a generator expression is more clear though.
Use a slice, not an arrray. Just create it using
reg := []string {"a","b","c"}
An alternative would have been to convert your array to a slice when joining :
fmt.Println(strings.Join(reg[:],","))
Read the Go blog about the differences between slices and arrays.
From Standard docs., 3.6.1.2 Main Function,
It shall have a return type of type int, but otherwise its type is implementation-defined. All implementations shall allow both of the following definitions of main:
int main() { / ... / }
and
int main(int argc, char* argv[]) { / ... / }
In the latter form
argc
shall be the number of arguments passed to the program from the environment in which the program is run.If argc is nonzero these arguments shall be supplied in argv[0] through argv[argc-1] as pointers to the initial characters of null-terminated multibyte strings.....
Hope that helps..
An excellent explanation can be found here: Generate script in SQL Server Management Studio
Courtesy Ali Issa Here's what you have to do:
If you want to create a script that just generates the tables (no data) you can skip the advanced part of the instructions!
In csh (as opposed to bash) you can do exactly what you want.
alias print 'lpr \!^ -Pps5'
print memo.txt
The notation \!^
causes the argument to be inserted in the command at this point.
The !
character is preceeded by a \
to prevent it being interpreted as a history command.
You can also pass multiple arguments:
alias print 'lpr \!* -Pps5'
print part1.ps glossary.ps figure.ps
(Examples taken from http://unixhelp.ed.ac.uk/shell/alias_csh2.1.html .)
In SQL Server 2008 and above just do this:
SELECT DATEADD(day, 1, Getdate()) AS DateAdd;
You can use following format:
<connectionStrings>
<add name="ConStringBDName" connectionString="Data Source=serverpath;Initial Catalog=YourDataBaseName;Integrated Security=SSPI;" providerName="System.Data.SqlClient" />
</connectionStrings>
Most probably you will fing connectionstring tag in web.config after <appSettings>
Try out this.
Although a bit late, I've come across this question while searching the solution for the same problem, so I hope it can be of any help...
Found myself in the same darkness than you. Just found this article, which explains some new hints introduced in NetBeans 7.4, including this one:
https://blogs.oracle.com/netbeansphp/entry/improve_your_code_with_new
The reason why it has been added is because superglobals usually are filled with user input, which shouldn't ever be blindly trusted. Instead, some kind of filtering should be done, and that's what the hint suggests. Filter the superglobal value in case it has some poisoned content.
For instance, where I had:
$_SERVER['SERVER_NAME']
I've put instead:
filter_input(INPUT_SERVER, 'SERVER_NAME', FILTER_SANITIZE_STRING)
You have the filter_input and filters doc here:
I just came out with this:
input[type="checkbox"] {display:none;}_x000D_
input[type="checkbox"] + label:before {content:"?";}_x000D_
input:checked + label:before {content:"?";}_x000D_
label:hover {color:blue;}
_x000D_
<input id="check" type="checkbox" /><label for="check">Checkbox</label>
_x000D_
Of course, thanks to this, you can change the value of content
to your needs and use an image if you wish or use another font...
The main interest here is that:
The checkbox size stays proportional to the text size
You can control the aspect, the color, the size of the checkbox
No extra HTML needed !
Only 3 lines of CSS needed (the last one is just to give you ideas)
Edit:
As pointed out in the comment, the checkbox won't be accessible by key navigation. You should probably add tabindex=0
as a property for your label to make it focusable.
A merge conflict occurs when two branches you're trying to merge both changed the same part of the same file. You can generate a list of conflicts with git status
.
When the conflicted line is encountered, Git will edit the content of the affected files with visual indicators that mark both sides of the conflicting content.
<<<<<<< HEAD
conflicted text from HEAD
=======
conflicted text from merging_branch
>>>>>>> merging_branch
When you fix your conflicted files and you are ready to merge, all you have to do is run git add
and git commit
to generate the merge commit. Once the commit was made ,git push

The easiest way is to redirect the output of the echo
by >>
:
echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile
The with
function will let you use shorthand column references and sum
will count TRUE
results from the expression(s).
sum(with(aaa, sex==1 & group1==2))
## [1] 3
sum(with(aaa, sex==1 & group2=="A"))
## [1] 2
As @mnel pointed out, you can also do:
nrow(aaa[aaa$sex==1 & aaa$group1==2,])
## [1] 3
nrow(aaa[aaa$sex==1 & aaa$group2=="A",])
## [1] 2
The benefit of that is that you can do:
nrow(aaa)
## [1] 6
And, the behaviour matches Stata's count
almost exactly (syntax notwithstanding).
In WSDL definition, bindings contain operations, here comes style for each operation.
Document : In WSDL file, it specifies types details either having inline Or imports XSD document, which describes the structure(i.e. schema) of the complex data types being exchanged by those service methods which makes loosely coupled. Document style is default.
In WSDL types element looks as follows:
<types>
<xsd:schema>
<xsd:import schemaLocation="http://localhost:9999/ws/hello?xsd=1" namespace="http://ws.peter.com/"/>
</xsd:schema>
</types>
The schema is importing from external reference.
RPC :In WSDL file, it does not creates types schema, within message elements it defines name and type attributes which makes tightly coupled.
<types/>
<message name="getHelloWorldAsString">
<part name="arg0" type="xsd:string"/>
</message>
<message name="getHelloWorldAsStringResponse">
<part name="return" type="xsd:string"/>
</message>
RPC : No types in WSDL
Document: Types section would be available in WSDL
You can just use the normal termios header and normal termios structure (it's the same as the termios2 when using header asm/termios).
So, you open the device using open() and get a file descriptor, then use it in tcgetattr()
to fill your termios structure.
Then clear CBAUD
and set CBAUDEX
on c_cflag
.
CBAUDEX
has the same value as BOTHER.
After setting this, you can set a custom baud rate using normal functions, like cfsetspeed()
, specifying the desired baud rate as an integer.
I agree with Petar Ivanov but it is best if we implement in following way:
public String replace(String str, int index, char replace){
if(str==null){
return str;
}else if(index<0 || index>=str.length()){
return str;
}
char[] chars = str.toCharArray();
chars[index] = replace;
return String.valueOf(chars);
}
The simplest is to just give the 'trans' (formerly 'formatter' argument the name of the log function:
m + geom_boxplot() + scale_y_continuous(trans='log10')
EDIT: Or if you don't like that, then either of these appears to give different but useful results:
m <- ggplot(diamonds, aes(y = price, x = color), log="y")
m + geom_boxplot()
m <- ggplot(diamonds, aes(y = price, x = color), log10="y")
m + geom_boxplot()
EDIT2 & 3: Further experiments (after discarding the one that attempted successfully to put "$" signs in front of logged values):
fmtExpLg10 <- function(x) paste(round_any(10^x/1000, 0.01) , "K $", sep="")
ggplot(diamonds, aes(color, log10(price))) +
geom_boxplot() +
scale_y_continuous("Price, log10-scaling", trans = fmtExpLg10)
Note added mid 2017 in comment about package syntax change:
scale_y_continuous(formatter = 'log10') is now scale_y_continuous(trans = 'log10') (ggplot2 v2.2.1)
To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100
in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application.
If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.
Real life example for:
**1) Singly linked list **
2) Doubly linked list
3) Circular linked list
Your code, as written, works. You’re probably trying to achieve something unrelated, but similar:
std::string c = "hello" + "world";
This doesn’t work because for C++ this seems like you’re trying to add two char
pointers. Instead, you need to convert at least one of the char*
literals to a std::string
. Either you can do what you’ve already posted in the question (as I said, this code will work) or you do the following:
std::string c = std::string("hello") + "world";
Another way:
import math
def hextobinary(hex_string):
s = int(hex_string, 16)
num_digits = int(math.ceil(math.log(s) / math.log(2)))
digit_lst = ['0'] * num_digits
idx = num_digits
while s > 0:
idx -= 1
if s % 2 == 1: digit_lst[idx] = '1'
s = s / 2
return ''.join(digit_lst)
print hextobinary('abc123efff')
It depends on your application. There are some considerations:
The Miller-Rabin and analogue tests are only faster than a sieve for numbers over a certain size (somewhere around a few million, I believe). Below that, using a trial division (if you just have a few numbers) or a sieve is faster.
If you've followed Adam's instructions and you're still getting this error make sure you've installed the right variants (x86 or x64).
I had VC14x64 with PHP7x86 and I still got this error. Changing PHP7 to x64 fixed it. It's easy to miss you accidentally installed the wrong version.
hyperlink1.NavigateUrl = "#"; or
hyperlink1.attributes["href"] = "#"; or

The imshow()
function with parameters interpolation='nearest'
and cmap='hot'
should do what you want.
import matplotlib.pyplot as plt
import numpy as np
a = np.random.random((16, 16))
plt.imshow(a, cmap='hot', interpolation='nearest')
plt.show()
Be careful to check if
display_errors
or
error_reporting
is active (not a comment) somewhere else in the ini file.
My development server refused to display errors after upgrade to Kubuntu 16.04 - I had checked php.ini numerous times ... turned out that there was a diplay_errors = off; about 100 lines below my
display_errors = on;
So remember the last one counts!
In new jQuery 1.5 you can use:
$.ajax({

url: "http://localhost:99000/Services.svc/ReturnPersons",
dataType: "jsonp",
success: readData(data),

alert(xhr.status);
alert(thrownError);
}
})
Remove Postmaster file in "C:\Program Files\PostgreSQL\9.6\data"
and restart the PostgreSQL services
For me the error was the files under js folder not included in the project this solve my issue :
1- In the solution explorer toolbar click Show All Files.
2- open js folder and select all files under the folder
3- right click then select include In Project
4- Save and build your application then its working correct and load .css and .js files
PHP by itself has no SMS module or functions and doesn't allow you to send SMS.
SMS ( Short Messaging System) is a GSM technology an you need a GSM provider that will provide this service for you and may have an PHP API implementation for it.
Usually people in telecom business use Asterisk to handle calls and sms programming.
Calendar.get
takes as argument one of the standard Calendar fields, like YEAR
or MONTH
not a month name.
Calendar.JANUARY
is 0, which is also the value of Calendar.ERA
, so Calendar.getInstance().get(0)
will return the era, in this case Calendar.AD
, which is 1.
For the first part of your question, note that, as is wildly documented, months start at 0, so 10 is actually November.
public static int[] strArrayToIntArray(String[] a){
int[] b = new int[a.length];
for (int i = 0; i < a.length; i++) {
b[i] = Integer.parseInt(a[i]);
}
return b;
}
This is a simple function, that should help you. You can use him like this:
int[] arr = strArrayToIntArray(/*YOUR STR ARRAY*/);
For debugging purposes. Recursive write an array of nested arrays to a string. Used foreach. Function stores National Language characters.
function q($input)
{
$glue = ', ';
$function = function ($v, $k) use (&$function, $glue) {
if (is_array($v)) {
$arr = [];
foreach ($v as $key => $value) {
$arr[] = $function($value, $key);
}
$result = "{" . implode($glue, $arr) . "}";
} else {
$result = sprintf("%s=\"%s\"", $k, var_export($v, true));
}
return $result;
};
return implode($glue, array_map($function, $input, array_keys($input))) . "\n";
}
OK Here is a Good And Proper Solution
You have a Div call with an id="myDiv"
so the function goes.
function GetScrollerEndPoint()
{
var scrollHeight = $("#myDiv").prop('scrollHeight');
var divHeight = $("#myDiv").height();
var scrollerEndPoint = scrollHeight - divHeight;
var divScrollerTop = $("#myDiv").scrollTop();
if(divScrollerTop === scrollerEndPoint)
{
//Your Code
//The Div scroller has reached the bottom
}
}
Since PHP 5.4 you can use:
htmlspecialchars($string, ENT_XML1);
You should specify the encoding, such as:
htmlspecialchars($string, ENT_XML1, 'UTF-8');
Note that the above will only convert:
&
to &
<
to <
>
to >
If you want to escape text for use in an attribute enclosed in double quotes:
htmlspecialchars($string, ENT_XML1 | ENT_COMPAT, 'UTF-8');
will convert "
to "
in addition to &
, <
and >
.
And if your attributes are enclosed in single quotes:
htmlspecialchars($string, ENT_XML1 | ENT_QUOTES, 'UTF-8');
will convert '
to '
in addition to &
, <
, >
and "
.
(Of course you can use this even outside of attributes).
If you are talking about syncing a forked repo then you can follow these steps.
How to sync a fork repository from git
check your current git branch
git branch
checkout to master if you are not on master
git checkout master
Fetch the upstream repository if you have correct access rights
git fetch upstream
If you are getting below error then run
git remote add upstream [email protected]:upstream_clone_repo_url/xyz.git
fatal: 'upstream/master' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
Now run the below command.
git fetch upstream
Now if you are on master then merge the upstream/master into master branch
git merge upstream/master
That's it!!
Crosscheck via git remote
command, more specific git remote -v
If I also have commit rights to the upstream repo, I can create a local upstream branch and do work that will go upstream there.
@Jonathan Sampson i think your solution is wrong if you use multiple @media.
You should use (min-width first):
@media screen and (min-width:400px) and (max-width:900px){
...
}
you can also use ranges by using:
b = df[(df['a'] > 1) & (df['a'] < 5)]
Since the count is the intended final value, in your query pass
$this->db->distinct();
$this->db->select('accessid');
$this->db->where('record', $record);
$query = $this->db->get()->result_array();
return count($query);
The count the retuned value
IF EXISTS()
is semantically incorrect. EXISTS
condition can be used only inside a SQL statement. So you might rewrite your pl/sql block as follows:
declare
l_exst number(1);
begin
select case
when exists(select ce.s_regno
from courseoffering co
join co_enrolment ce
on ce.co_id = co.co_id
where ce.s_regno=403
and ce.coe_completionstatus = 'C'
and ce.c_id = 803
and rownum = 1
)
then 1
else 0
end into l_exst
from dual;
if l_exst = 1
then
DBMS_OUTPUT.put_line('YES YOU CAN');
else
DBMS_OUTPUT.put_line('YOU CANNOT');
end if;
end;
Or you can simply use count
function do determine the number of rows returned by the query, and rownum=1
predicate - you only need to know if a record exists:
declare
l_exst number;
begin
select count(*)
into l_exst
from courseoffering co
join co_enrolment ce
on ce.co_id = co.co_id
where ce.s_regno=403
and ce.coe_completionstatus = 'C'
and ce.c_id = 803
and rownum = 1;
if l_exst = 0
then
DBMS_OUTPUT.put_line('YOU CANNOT');
else
DBMS_OUTPUT.put_line('YES YOU CAN');
end if;
end;
The location of jfxrt.jar in Oracle Java 7 is:
<JRE_HOME>/lib/jfxrt.jar
The location of jfxrt.jar in Oracle Java 8 is:
<JRE_HOME>/lib/ext/jfxrt.jar
The <JRE_HOME>
will depend on where you installed the Oracle Java and may differ between Linux distributions and installations.
jfxrt.jar is not in the Linux OpenJDK 7 (which is what you are using).
An open source package which provides JavaFX 8 for Debian based systems such as Ubuntu is available. To install this package it is necessary to install both the Debian OpenJDK 8 package and the Debian OpenJFX package. I don't run Debian, so I'm not sure where the Debian OpenJFX package installs jfxrt.jar.
Use Oracle Java 8.
With Oracle Java 8, JavaFX is both included in the JDK and is on the default classpath. This means that JavaFX classes will automatically be found both by the compiler during the build and by the runtime when your users use your application. So using Oracle Java 8 is currently the best solution to your issue.
OpenJDK for Java 8 could include JavaFX (as JavaFX for Java 8 is now open source), but it will depend on the OpenJDK package assemblers as to whether they choose to include JavaFX 8 with their distributions. I hope they do, as it should help remove the confusion you experienced in your question and it also provides a great deal more functionality in OpenJDK.
My understanding is that although JavaFX has been included with the standard JDK since version JDK 7u6
Yes, but only the Oracle JDK.
The JavaFX version bundled with Java 7 was not completely open source so it could not be included in the OpenJDK (which is what you are using).
In you need to use Java 7 instead of Java 8, you could download the Oracle JDK for Java 7 and use that. Then JavaFX will be included with Java 7. Due to the way Oracle configured Java 7, JavaFX won't be on the classpath. If you use Java 7, you will need to add it to your classpath and use appropriate JavaFX packaging tools to allow your users to run your application. Some tools such as e(fx)clipse and NetBeans JavaFX project type will take care of classpath issues and packaging tasks for you.
JObject obj = JObject.Parse(json);
var attributes = obj["parent"]["child"]...["your desired element"].ToList<JToken>();
foreach (JToken attribute in attributes)
{
JProperty jProperty = attribute.ToObject<JProperty>();
string propertyName = jProperty.Name;
}
If you want to set 777 permission to your created file than you can use the following method:
public void setPermission(File file) throws IOException{
Set<PosixFilePermission> perms = new HashSet<>();
perms.add(PosixFilePermission.OWNER_READ);
perms.add(PosixFilePermission.OWNER_WRITE);
perms.add(PosixFilePermission.OWNER_EXECUTE);
perms.add(PosixFilePermission.OTHERS_READ);
perms.add(PosixFilePermission.OTHERS_WRITE);
perms.add(PosixFilePermission.OTHERS_EXECUTE);
perms.add(PosixFilePermission.GROUP_READ);
perms.add(PosixFilePermission.GROUP_WRITE);
perms.add(PosixFilePermission.GROUP_EXECUTE);
Files.setPosixFilePermissions(file.toPath(), perms);
}
For those who had trouble with the apt-get, or with the long instruction. I solved it in a relatively painless way.
This worked perfectly for me.
mysql> use mysql; mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'my-password-here';
To determine the class of an object simply call:
someObject.getClass()
You can abbreviate this to someObject.class
in most cases. However, if you use this on a Map
it will try to retrieve the value with key 'class'. Because of this, I always use getClass()
even though it's a little longer.
If you want to check if an object implements a particular interface or extends a particular class (e.g. Date) use:
(somObject instanceof Date)
or to check if the class of an object is exactly a particular class (not a subclass of it), use:
(somObject.getClass() == Date)
I´ve done a tiny solution using only jQuery.
First, you need to put an additional class to your <div class="modal-body">
I called "ativa-scroll", so it becomes something like this:
<div class="modal-body ativa-scroll">
So now just put this piece of code on your page, near your JS loading:
<script type="text/javascript">
$(document).ready(ajustamodal);
$(window).resize(ajustamodal);
function ajustamodal() {
var altura = $(window).height() - 155; //value corresponding to the modal heading + footer
$(".ativa-scroll").css({"height":altura,"overflow-y":"auto"});
}
</script>
I works perfectly for me, also in a responsive way! :)
Run:
$ git rebase --interactive commit_hash^
each ^
indicates how many commits back you want to edit, if it's only one (the commit hash that you specified), then you just add one ^
.
Using Vim you change the words pick
to reword
for the commits you want to change, save and quit(:wq
). Then git will prompt you with each commit that you marked as reword so you can change the commit message.
Each commit message you have to save and quit(:wq
) to go to the next commit message
If you want to exit without applying the changes, press :q!
EDIT: to navigate in vim
you use j
to go up, k
to go down, h
to go left, and l
to go right( all this in NORMAL
mode, press ESC
to go to NORMAL
mode ).
To edit a text, press i
so that you enter the INSERT
mode, where you insert text.
Press ESC
to go back to NORMAL
mode :)
UPDATE: Here's a great link from github listing How to undo (almost) anything with git
This is probably because an empty line at the end of your input file.

First I would recommend you always refer docs before you start a new thing.
We have SchedulerFactory
which schedules Job based on the Cron Expression given to it.
//Create instance of factory
SchedulerFactory schedulerFactory=new StdSchedulerFactory();
//Get schedular
Scheduler scheduler= schedulerFactory.getScheduler();
//Create JobDetail object specifying which Job you want to execute
JobDetail jobDetail=new JobDetail("myJobClass","myJob1",MyJob.class);
//Associate Trigger to the Job
CronTrigger trigger=new CronTrigger("cronTrigger","myJob1","0 0/1 * * * ?");
//Pass JobDetail and trigger dependencies to schedular
scheduler.scheduleJob(jobDetail,trigger);
//Start schedular
scheduler.start();
MyJob.class
public class MyJob implements Job{
@Override
public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
System.out.println("My Logic");
}
}
In addition set the proxy for the command line session Open a command line where you might want to run your script
netsh winhttp set proxy YourProxySERVER:yourProxyPORT
run your script in that terminal.
I tried the answer but it didn't worked for me. This is what i ended up doing:
Create a new controller DefaultController. In index action, i wrote one line redirect:
return Redirect("~/Default.aspx")
In RouteConfig.cs, change controller="Default" for the route.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Default", action = "Index", id = UrlParameter.Optional }
);
Its complete installation nightmare, but I'll give one more hope you can avoid building opencv from source:
pip install opencv-contrib-python
I created an extension method (gosh I wish Java had these) called IsEmpty
as follows:
public static bool IsEmpty(this DataRow row)
{
return row == null || row.ItemArray.All(i => i is DBNull);
}
The other answers here are correct. I just felt mine lent brevity in its succinct use of Linq to Objects. BTW, this is really useful in conjunction with Excel parsing since users may tack on a row down the page (thousands of lines) with no regard to how that affects parsing the data.
In the same class, I put any other helpers I found useful, like parsers so that if the field contains text that you know should be a number, you can parse it fluently. Minor pro tip for anyone new to the idea. (Anyone at SO, really? Nah!)
With that in mind, here is an enhanced version:
public static bool IsEmpty(this DataRow row)
{
return row == null || row.ItemArray.All(i => i.IsNullEquivalent());
}
public static bool IsNullEquivalent(this object value)
{
return value == null
|| value is DBNull
|| string.IsNullOrWhiteSpace(value.ToString());
}
Now you have another useful helper, IsNullEquivalent
which can be used in this context and any other, too. You could extend this to include things like "n/a"
or "TBD"
if you know that your data has placeholders like that.
Use database field type BLOB to store arrays.
Ref: http://us.php.net/manual/en/function.serialize.php
Return Values
Returns a string containing a byte-stream representation of value that can be stored anywhere.
Note that this is a binary string which may include null bytes, and needs to be stored and handled as such. For example, serialize() output should generally be stored in a BLOB field in a database, rather than a CHAR or TEXT field.
For any special characters you should use '\'. So, for matching parentheses - /\(/
I have researched a lot for cleaning Backstack, and finally see Transaction BackStack and its management. Here is the solution that worked best for me.
// CLEAR BACK STACK.
private void clearBackStack() {
final FragmentManager fragmentManager = getSupportFragmentManager();
while (fragmentManager.getBackStackEntryCount() != 0) {
fragmentManager.popBackStackImmediate();
}
}
The above method loops over all the transactions in the backstack and removes them immediately one at a time.
Note: above code sometime not work and i face ANR because of this code,so please do not try this.
Update below method remove all fregment of that "name" from backstack.
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.popBackStack("name",FragmentManager.POP_BACK_STACK_INCLUSIVE);
It depends on the situation INSERT can actually have a where clause.
For example if you are matching values from a form.
Consider INSERT INTO Users(name,email,weight, desiredWeight) VALUES (fred,[email protected],160,145) WHERE name != fred AND email != [email protected]
Makes sense doesn't it?
We can create a new CSS class for div.

Okay, I'm writing this answer by extending wmky's answer above & also, assuming that you've configured mysql for your metastore instead of derby.
select PART_NAME FROM PARTITIONS WHERE TBL_ID=(SELECT TBL_ID FROM TBLS WHERE TBL_NAME='<table_name>');
The above query gives you all possible values of the partition columns.
Example:

OK
time timestamp
..
day date
file_date varchar(8)
# Partition Information
# col_name data_type comment
day date
file_date varchar(8)
Time taken: 1.075 seconds, Fetched: 28 row(s)
I'm going to fetch the values of partition columns.
mysql> select PART_NAME FROM PARTITIONS WHERE TBL_ID=(SELECT TBL_ID FROM TBLS WHERE TBL_NAME='clicks_fact');
+-----------------------------------+
| PART_NAME |
+-----------------------------------+

This is a common code adapted from another examples:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("http://www.google.com/")
#open tab
# ... take the code from the options below
# Load a page
driver.get('http://bings.com')
# Make the tests...
# close the tab
driver.quit()
the possible ways were:
Sending <CTRL> + <T>
to one element
#open tab
driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 't')
Sending <CTRL> + <T>
via Action chains
ActionChains(driver).key_down(Keys.CONTROL).send_keys('t').key_up(Keys.CONTROL).perform()
Execute a javascript snippet
driver.execute_script('''window.open("http://bings.com","_blank");''')
In order to achieve this you need to ensure that the preferences browser.link.open_newwindow and browser.link.open_newwindow.restriction are properly set. The default values in the last versions are ok, otherwise you supposedly need:
fp = webdriver.FirefoxProfile()
fp.set_preference("browser.link.open_newwindow", 3)
fp.set_preference("browser.link.open_newwindow.restriction", 2)
driver = webdriver.Firefox(browser_profile=fp)
the problem is that those preferences preset to other values and are frozen at least selenium 3.4.0. When you use the profile to set them with the java binding there comes an exception and with the python binding the new values are ignored.
In Java there is a way to set those preferences without specifying a profile object when talking to geckodriver, but it seem to be not implemented yet in the python binding:
FirefoxOptions options = new FirefoxOptions().setProfile(fp);
options.addPreference("browser.link.open_newwindow", 3);
options.addPreference("browser.link.open_newwindow.restriction", 2);
FirefoxDriver driver = new FirefoxDriver(options);
The third option did stop working for python in selenium 3.4.0.
The first two options also did seem to stop working in selenium 3.4.0. They do depend on sending CTRL key event to an element. At first glance it seem that is a problem of the CTRL key, but it is failing because of the new multiprocess feature of Firefox. It might be that this new architecture impose new ways of doing that, or maybe is a temporary implementation problem. Anyway we can disable it via:
fp = webdriver.FirefoxProfile()
fp.set_preference("browser.tabs.remote.autostart", False)
fp.set_preference("browser.tabs.remote.autostart.1", False)
fp.set_preference("browser.tabs.remote.autostart.2", False)
driver = webdriver.Firefox(browser_profile=fp)
... and then you can use successfully the first way.
You have an option to define collation order at the time of defining your table. If you define a case-sensitive order, your LIKE
operator will behave in a case-sensitive way; if you define a case-insensitive collation order, the LIKE
operator will ignore character case as well:
CREATE TABLE Test (
CI_Str VARCHAR(15) COLLATE Latin1_General_CI_AS -- Case-insensitive
, CS_Str VARCHAR(15) COLLATE Latin1_General_CS_AS -- Case-sensitive
);
Here is a quick demo on sqlfiddle showing the results of collation order on searches with LIKE
.
CTRL + H is actually the right answer, but the scope in which it was pressed is actually pretty important. When you have last clicked on file you're working on, you'll get a different search window - Java Search:

There is nothing wrong with your code. It's the NBC.com doing tricks on you. When NBC.com decides that your browser is not capable of displaying PDF, it simply sends back a webpage regardless what you are requesting, even if it doesn't exist.
You need to trick it back by telling it your browser is capable, something like,
conn.setRequestProperty("User-Agent",

The Queue interface extends java.util.Collection with additional insertion, extraction, and inspection operations like:
+offer(element: E):
boolean // Inserting an element
+poll(): E
// Retrieves the element and returns NULL if queue is empty
+remove(): E
// Retrieves and removes the element and throws an Exception if queue is empty
+peek(): E
// Retrieves,but does not remove, the head of this queue, returning null if this queue is empty.
+element(): E
// Retrieves, but does not remove, the head of this queue, throws an exception if te queue is empty.
Example Code for implementing Queue:
java.util.Queue<String> queue = new LinkedList<>();
queue.offer("Hello");
queue.offer("StackOverFlow");
queue.offer("User");
System.out.println(queue.peek());
while (queue.size() > 0){
System.out.println(queue.remove() + " ");
}
//Since Queue is empty now so this will return NULL
System.out.println(queue.peek());
Output Of the code :
Hello
Hello
StackOverFlow
User

I prefer parsing results of dumpsys window windows
over dumpsys activity
adb shell dumpsys window windows | grep -E 'mCurrentFocus|mFocusedApp'
Keyguard or Recent tasks list used to not show up as Activities but you were able to see them with mCurrentFocus
. I have explained why in this answer.
Simply casting to an int truncates the float, which if your system internally represent 2.0 as 1.9999999999, you will not get what you expect. The various printf conversions deal with this and properly round the number when converting. So to get a more accurate value, the conversion is even more complicated than you might first expect:
package main
import (
"fmt"
"strconv"
)
func main() {
floats := []float64{1.9999, 2.0001, 2.0}
for _, f := range floats {
t := int(f)
s := fmt.Sprintf("%.0f", f)
if i, err := strconv.Atoi(s); err == nil {
fmt.Println(f, t, i)
} else {
fmt.Println(f, t, err)
}
}
}

If your object could contain any key/value pairs, you could declare an interface called keyable
like :
interface keyable {
[key: string]: any
}
then use it as follows :
let countryProviders: keyable[];
or
let countryProviders: Array<keyable>;
Because Stage
is required, all one-to-many relationships where Stage
is involved will have cascading delete enabled by default. It means, if you delete a Stage
entity
Side
Card
and because Card
and Side
have a required one-to-many relationship with cascading delete enabled by default again it will then cascade from Card
to Side
So, you have two cascading delete paths from Stage
to Side
- which causes the exception.
You must either make the Stage
optional in at least one of the entities (i.e. remove the [Required]
attribute from the Stage
properties) or disable cascading delete with Fluent API (not possible with data annotations):
modelBuilder.Entity<Card>()
.HasRequired(c => c.Stage)
.WithMany()
.WillCascadeOnDelete(false);
modelBuilder.Entity<Side>()
.HasRequired(s => s.Stage)
.WithMany()
.WillCascadeOnDelete(false);

I got this working : -
$.get('api.php', 'client=mikescafe', function(data) {
...
});
It sends via get the string ?client=mikescafe then collect this variable in api.php, and use it in your mysql statement.
You're using the argument as a reference but actually it's a pointer. Change vector<int>*
to vector<int>&
. And you should really set search4
to something before using it.
If you use "=", a replica is created for the original arraylist in the second one, but the reference is same so if you change in one list , the other one will also get modified. Use this instead of "="
List_Of_Array1.addAll(List_Of_Array);
Sharing that in my case this error was because i forgot to update project.json with:
"buildOptions": {
"emitEntryPoint": true
}
Setting its background image to none also works:
button {
background-image: none;
}
You can create a folder with os.makedirs()
and use os.path.exists() to see if it already exists:
newpath = r'C:\Program Files\arbitrary'
if not os.path.exists(newpath):
os.makedirs(newpath)

If ctrl+c doesn't respond right away because your script is too long/complex, hold it.
The break command doesn't run when matlab is executing some of its deeper scripts, and either it won't log a ctrl sequence in the buffer, or it clears the buffer just before or just after it completes those pieces of code. In either case, when matlab returns to execute more of your script, it will recognize that you are holding ctrl+c and terminate.
For longer running programs, I usually try to find a good place to provide a status update and I always accompany that with some measure of time using tic and toc. Depending on what I am doing, I might use run time, segment time, some kind of average, etc...
For really long running programs, I found this to be exceptionally useful http://www.mathworks.com/matlabcentral/fileexchange/16649-send-text-message-to-cell-phone/content/send_text_message.m
but it looks like they have some newer functions for this too.

I'd like to add to bosnic's answer that any valid currency character is legal for an identifier in Java. th€is is a legal identifier, as is €this, and € as well. However, I can't figure out how to edit his or her answer, so I am forced to post this trivial addition.
The first regex will match one whitespace character. The second regex will reluctantly match one or more whitespace characters. For most purposes, these two regexes are very similar, except in the second case, the regex can match more of the string, if it prevents the regex match from failing. from http://www.coderanch.com/t/570917/java/java/regex-difference
When you parse the JSON representation, it'll become a JavaScript array of objects.
Because of this, you can use the .length
property of the JavaScript array to see how many elements are contained, and use a for
loop to enumerate it.
If the workspace is not that big you could backup to say dropbox as a private locked folder.
In order to get proper responses back from async methods, you need to put await while calling those task methods. That will wait for converting it back to the returned value type rather task type.
E.g var content = await StringAsyncTask (
where public async Task<String> StringAsyncTask ())
It's cleaner/safer to use the getters provided by google instead of accessing the properties like some did

There is no solution to this problem. As of IE11 on Windows 8, Microsoft no longer allows ActiveX plugins to run in its browser space. There is absolutely nothing that a third party developer can do about it.
A similar thing has recently happened with the Chrome browser which no longer supports NPAPI plugins. Instead Chrome only supports PPAPI plugins which are useless for system level tasks once performed by NPAPI plugins.
So developers needing browser support for system interactive plugins can only recommend either the Firefox browser or the ASPS web browser.
How about this: I used it with a mixin
non-compliant object
@Entity
@Getter
@NoArgsConstructor
public class Telemetry {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long pk;
private String id;
private String organizationId;
private String baseType;
private String name;
private Double lat;
private Double lon;
private Instant updateTimestamp;
}
Mixin:
@JsonAutoDetect(fieldVisibility = ANY, getterVisibility = NONE, setterVisibility = NONE)
public static class TelemetryMixin {}
Usage:
ObjectMapper om = objectMapper.addMixIn(Telemetry.class, TelemetryMixin.class);
Telemetry[] telemetries = om.readValue(someJson, Telemetry[].class);
There is nothing that says you couldn't foreach any number of classes and apply the same mixin.
If you're not familiar with mixins, they are conceptually simply: The structure of the mixin is super imposed on the target class (according to jackson, not as far as the JVM is concerned).
I also faced the same problem, and get the columns name and its types. Then cast(col_Name as Char) from table name. From this way i get the problem as '0000-00-00 00:00:00' then I Update as valid date and time the error gets away for my case.
What I'm missing in the other answers is a reference to how this relates to co- and contravariance and sub- and supertypes (that is, polymorphism) in general and to Java in particular. This may be well understood by the OP, but just in case, here it goes:
If you have a class Automobile
, then Car
and Truck
are their subtypes. Any Car can be assigned to a variable of type Automobile, this is well-known in OO and is called polymorphism. Covariance refers to using this same principle in scenarios with generics or delegates. Java doesn't have delegates (yet), so the term applies only to generics.
I tend to think of covariance as standard polymorphism what you would expect to work without thinking, because:
List<Car> cars;
List<Automobile> automobiles = cars;
// You'd expect this to work because Car is-a Automobile, but
// throws inconvertible types compile error.
The reason of the error is, however, correct: List<Car>
does not inherit from List<Automobile>
and thus cannot be assigned to each other. Only the generic type parameters have an inherit relationship. One might think that the Java compiler simply isn't smart enough to properly understand your scenario there. However, you can help the compiler by giving him a hint:
List<Car> cars;
List<? extends Automobile> automobiles = cars; // no error
The reverse of co-variance is contravariance. Where in covariance the parameter types must have a subtype relationship, in contravariance they must have a supertype relationship. This can be considered as an inheritance upper-bound: any supertype is allowed up and including the specified type:
class AutoColorComparer implements Comparator<Automobile>
public int compare(Automobile a, Automobile b) {
// Return comparison of colors
}
This can be used with Collections.sort:
public static <T> void sort(List<T> list, Comparator<? super T> c)
// Which you can call like this, without errors:
List<Car> cars = getListFromSomewhere();
Collections.sort(cars, new AutoColorComparer());
You could even call it with a comparer that compares objects and use it with any type.
A bit OT perhaps, you didn't ask, but it helps understanding answering your question. In general, when you get something, use covariance and when you put something, use contravariance. This is best explained in an answer to Stack Overflow question How would contravariance be used in Java generics?.
List<? extends Map<String, String>>
You use extends
, so the rules for covariance applies. Here you have a list of maps and each item you store in the list must be a Map<string, string>
or derive from it. The statement List<Map<String, String>>
cannot derive from Map
, but must be a Map
.
Hence, the following will work, because TreeMap
inherits from Map
:
List<Map<String, String>> mapList = new ArrayList<Map<String, String>>();
mapList.add(new TreeMap<String, String>());
but this will not:
List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new TreeMap<String, String>());
and this will not work either, because it does not satisfy the covariance constraint:
List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new ArrayList<String>()); // This is NOT allowed, List does not implement Map
This is probably obvious, but you may have already noted that using the extends
keyword only applies to that parameter and not to the rest. I.e., the following will not compile:
List<? extends Map<String, String>> mapList = new List<? extends Map<String, String>>();
mapList.add(new TreeMap<String, Element>()) // This is NOT allowed
Suppose you want to allow any type in the map, with a key as string, you can use extend
on each type parameter. I.e., suppose you process XML and you want to store AttrNode, Element etc in a map, you can do something like:
List<? extends Map<String, ? extends Node>> listOfMapsOfNodes = new...;
// Now you can do:
listOfMapsOfNodes.add(new TreeMap<Sting, Element>());
listOfMapsOfNodes.add(new TreeMap<Sting, CDATASection>());
Your target triplet indicates that your compiler is configured for the hard-float ABI. This means that the libgcc library will also be hardfp. The error message indicates that at least part of your system is using soft-float ABI.
If the compiler has multilib enabled (you can tell with -print-multi-lib
) then you can use -mfloat-abi=softfp
, but if not then that option won't help you much: gcc will happily generate softfp code, but then there'll be no compatible libgcc to link against.
Basically, hardfp and softfp are just not compatible. You need to get your whole system configured one way or the other.
EDIT: some distros are, or will be, "multiarch". If you have one of those then it's possible to install both ABIs at once, but that's done by doubling everything up -- the compatibility issues still exist.
Use UploadStringAsync
method:
WebClient webClient = new WebClient();
webClient.UploadStringCompleted += (s, e) =>
{
if (e.Error != null)
{
//handle your error here
}
else
{
//post was successful, so do what you need to do here
}
};
webClient.UploadStringAsync(new Uri(yourUri), UriKind.Absolute), "POST", yourParameters);
In .NET Core 3.1 you can do the following in the model class:
public bool? Active { get; set; }
In the DbContext OnModelCreating you add the default value.
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Foundation>()
.Property(b => b.Active)
.HasDefaultValueSql("1");
base.OnModelCreating(modelBuilder);
}
Resulting in the following in the database
Note: If you don't have nullable (bool?) for you property you will get the following warning
The 'bool' property 'Active' on entity type 'Foundation' is configured with a database-generated default. This default will always be used for inserts when the property has the value 'false', since this is the CLR default for the 'bool' type. Consider using the nullable 'bool?' type instead so that the default will only be used for inserts when the property value is 'null'.
I wrote a function for the FFT in Java: http://www.wikijava.org/wiki/The_Fast_Fourier_Transform_in_Java_%28part_1%29
It's in the Public Domain so you can use those functions everywhere (personal or business projects too). Just cite me in the credits and send me just a link of your work, and you're ok.
It is completely reliable. I've checked its output against the Mathematica's FFT and they were always correct until the 15th decimal digit. I think it's a very good FFT implementation for Java. I wrote it on the J2SE 1.6 version, and tested it on the J2SE 1.5-1.6 version.
If you count the number of instruction (it's a lot much simpler than a perfect computational complexity function estimation) you can clearly see that this version is great even if it's not optimized at all. I'm planning to publish the optimized version if there are enough requests.
Let me know if it was useful, and tell me any comment you like.

You can use Class.isArray()
public static boolean isArray(Object obj)
{
return obj!=null && obj.getClass().isArray();
}
This works for both object and primitive type arrays.
For toString take a look at Arrays.toString
. You'll have to check the array type and call the appropriate toString
method.
You can create a link , having get variable in href.
<a href="www.site.com/hello?getVar=value" >...</a>
You could do it with JavaScript with something like this:
<input onblur="checkLength(this)" id="groupidtext" type="text" style="width: 100px;" maxlength="6" />
<!-- Or use event onkeyup instead if you want to check every character strike -->
function checkLength(el) {
if (el.value.length != 6) {
alert("length must be exactly 6 characters")
}
}
Note this would work in older browsers which don't support HTML 5, but it relies on the user having JavaScript switched on.
This will let you read, write and create the file if it don't exist:
f = open('filename.txt','a+')
f = open('filename.txt','r+')
Often used commands:
f.readline() #Read next line
f.seek(0) #Jump to beginning
f.read(0) #Read all file
f.write('test text') #Write 'test text' to file
f.close() #Close file
Take a look at http://www.csharp-examples.net/download-files/ and msdn docs on webclient http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx
My suggestion is try the synchronous download as its more straightforward. you might get ideas on whether webclient parameters are wrong or the file is in incorrect format while trying this.
Here is a code sample..
private void btnDownload_Click(object sender, EventArgs e)
{
string filepath = textBox1.Text;
WebClient webClient = new WebClient();
webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
webClient.DownloadFileAsync(new Uri("http://mysite.com/myfile.txt"), filepath);
}
private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
progressBar.Value = e.ProgressPercentage;
}
private void Completed(object sender, AsyncCompletedEventArgs e)
{
MessageBox.Show("Download completed!");
}
Cleanest way I have come across is inspired by the sql style guide.
sql = """
SELECT field1, field2, field3, field4
FROM table
WHERE condition1 = 1
AND condition2 = 2;
"""
Essentially, the keywords that begin a clause should be right-aligned and the field names etc, should be left aligned. This looks very neat and is easier to debug as well.
This question keeps coming up when I search for ipython change pwd
even though I am not interested in a notebook
, but a terminal or qtconsole. Not finding a relevant config entry I tried:
# lines of code to run at IPython startup.
c.InteractiveShellApp.exec_lines = ['%cd /home/paul/mypy']
This is the base level shell
class; there are Terminal and Console (and probably notebook) entries that could further customize the action.
From the docs it looks like import
statements are most common in the entry, but it appears that many magic commands work as well.
If you're trying to invoke a Windows UAC prompt (the one that puts the whole screen black and asks if you're granting administrator privileges to the following task), RUNAS is not the smoothest way to do it, since:
Instead, try to copy & paste the following code to ensure that your batch file runs with administrator privileges:
@echo off
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"
if '%errorlevel%' NEQ '0' (
echo Requesting Admin access...
goto goUAC )
else goto goADMIN
:goUAC
echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
set params = %*:"=""
echo UAC.ShellExecute "cmd.exe", "/c %~s0 %params%", "", "runas", 1 >> "%temp%\getadmin.vbs"
"%temp%\getadmin.vbs"
del "%temp%\getadmin.vbs"
exit /B
:goADMIN
pushd "%CD%"
CD /D "%~dp0"
rem --- FROM HERE PASTE YOUR ADMIN-ENABLED BATCH SCRIPT ---
echo Stopping some Microsoft Service...
net stop sqlserveragent
rem --- END OF BATCH ----
This solution works 100% under Windows 7, 8.1 and 10 setups with UAC enabled.
Bit of a resurrect but for anyone else coming to this question, take a look at the Micro editor. It's a small standalone EXE with no dependencies and with native Windows 32\64 versions. Works well in both PowerShell and CMD.EXE.
PreparedStatement:
1) Precompilation and DB-side caching of the SQL statement leads to overall faster execution and the ability to reuse the same SQL statement in batches.
2) Automatic prevention of SQL injection attacks by builtin escaping of quotes and other special characters. Note that this requires that you use any of the PreparedStatement setXxx() methods to set the value.
Kotlin Version
To retain current font in addition to text style:
textView.apply {
setTypeface(typeface, Typeface.NORMAL)
// or
setTypeface(typeface, Typeface.BOLD)
// or
setTypeface(typeface, Typeface.ITALIC)
// or
setTypeface(typeface, Typeface.BOLD_ITALIC)
}
You can do that with a single statement and a subquery in nearly all relational databases.
INSERT INTO targetTable(field1)
SELECT field1
FROM myTable
WHERE NOT(field1 IN (SELECT field1 FROM targetTable))
Certain relational databases have improved syntax for the above, since what you describe is a fairly common task. SQL Server has a MERGE
syntax with all kinds of options, and MySQL has optional INSERT OR IGNORE
syntax.
Edit: SmallSQL's documentation is fairly sparse as to which parts of the SQL standard it implements. It may not implement subqueries, and as such you may be unable to follow the advice above, or anywhere else, if you need to stick with SmallSQL.
You can run H2 web server within your application that will access the same in-memory database. You can also access the H2 running in server mode using any generic JDBC client like SquirrelSQL.
UPDATE:
Server webServer = Server.createWebServer("-web,-webAllowOthers,true,-webPort,8082").start();
Server server = Server.createTcpServer("-tcp,-tcpAllowOthers,true,-tcpPort,9092").start();
Now you can connect to your database via jdbc:h2:mem:foo_db
URL within the same process or browse the foo_db
database using localhost:8082
. Remember to close both servers. See also: H2 database in memory mode cannot be accessed by Console.
You can also use Spring:
<bean id="h2Server" class="org.h2.tools.Server" factory-method="createTcpServer" init-method="start" destroy-method="stop" depends-on="h2WebServer">
<constructor-arg value="-tcp,-tcpAllowOthers,true,-tcpPort,9092"/>
</bean>
<bean id="h2WebServer" class="org.h2.tools.Server" factory-method="createWebServer" init-method="start" destroy-method="stop">
<constructor-arg value="-web,-webAllowOthers,true,-webPort,8082"/>
</bean>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close" depends-on="h2Server">
<property name="driverClass" value="org.h2.Driver"/>
<property name="jdbcUrl" value="jdbc:h2:mem:foo_db"/>
</bean>
BTW you should only depend on assertions and not on manual peeking the database contents. Use this only for troubleshooting.
N.B. if you use Spring test framework you won't see changes made by a running transaction and this transaction will be rolled back immediately after the test.
I created this simple example from different search results on the internet.
public static ServiceHost CreateServiceHost(Type serviceInterface, Type implementation)
{
//Create base address
string baseAddress = "net.pipe://localhost/MyService";
ServiceHost serviceHost = new ServiceHost(implementation, new Uri(baseAddress));
//Net named pipe
NetNamedPipeBinding binding = new NetNamedPipeBinding { MaxReceivedMessageSize = 2147483647 };
serviceHost.AddServiceEndpoint(serviceInterface, binding, baseAddress);
//MEX - Meta data exchange
ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
serviceHost.Description.Behaviors.Add(behavior);
serviceHost.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexNamedPipeBinding(), baseAddress + "/mex/");
return serviceHost;
}
Using the above URI I can add a reference in my client to the web service.
You can pass custom http headers with RestTemplate exchange method as below.
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(new MediaType[] { MediaType.APPLICATION_JSON }));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("X-TP-DeviceID", "your value");
HttpEntity<RestRequest> entityReq = new HttpEntity<RestRequest>(request, headers);
RestTemplate template = new RestTemplate();
ResponseEntity<RestResponse> respEntity = template
.exchange("RestSvcUrl", HttpMethod.POST, entityReq, RestResponse.class);
EDIT : Below is the updated code. This link has several ways of calling rest service with examples
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("X-TP-DeviceID", "your value");
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<Mall[]> respEntity = restTemplate.exchange(url, HttpMethod.POST, entity, Mall[].class);
Mall[] resp = respEntity.getBody();
Laravel is not actually that slow. 500-1000ms is absurd; I got it down to 20ms in debug mode.
The problem was Vagrant/VirtualBox + shared folders. I didn't realize they incurred such a performance hit. I guess because Laravel has so many dependencies (loads ~280 files) and each of those file reads is slow, it adds up really quick.
kreeves pointed me in the right direction, this blog post describes a new feature in Vagrant 1.5 that lets you rsync your files into the VM rather than using a shared folder.
There's no native rsync client on Windows, so you'll have to use cygwin. Install it, and make sure to check off Net/rsync. Add C:\cygwin64\bin
to your paths. [Or you can install it on Win10/Bash]
Vagrant introduces the new feature. I'm using Puphet, so my Vagrantfile looks a bit funny. I had to tweak it to look like this:
data['vm']['synced_folder'].each do |i, folder|
if folder['source'] != '' && folder['target'] != '' && folder['id'] != ''
config.vm.synced_folder "#{folder['source']}", "#{folder['target']}",
id: "#{folder['id']}",
type: "rsync",
rsync__auto: "true",
rsync__exclude: ".hg/"
end
end
Once you're all set up, try vagrant up
. If everything goes smoothly your machine should boot up and it should copy all the files over. You'll need to run vagrant rsync-auto
in a terminal to keep the files up to date. You'll pay a little bit in latency, but for 30x faster page loads, it's worth it!
If you're using PhpStorm, it's auto-upload feature works even better than rsync. PhpStorm creates a lot of temporary files which can trip up file watchers, but if you let it handle the uploads itself, it works nicely.
One more option is to use lsyncd. I've had great success using this on Ubuntu host -> FreeBSD guest. I haven't tried it on a Windows host yet.
The next version of Windows (Windows 7) will be able to snap windows to the left or right half of the screen. Doesn't help right now, but it's something to look forward to.

>> my_var = 5
>> my_var_name = [ k for k,v in locals().items() if v == my_var][0]
>> my_var_name
'my_var'
In case you get an error if myvar points to another variable, try this (suggested by @mherzog)-
>> my_var = 5
>> my_var_name = [ k for k,v in locals().items() if v is my_var][0]
>> my_var_name
'my_var'
locals() - Return a dictionary containing the current scope's local variables. by iterating through this dictionary we can check the key which has a value equal to the defined variable, just extracting the key will give us the text of variable in string format.

If the strings are the same length, then I would go for '%x' % ()
of the built-in xor (^
).
Examples -
>>>a = '290b6e3a'
>>>b = 'd6f491c5'
>>>'%x' % (int(a,16)^int(b,16))
'ffffffff'
>>>c = 'abcd'
>>>d = '12ef'
>>>'%x' % (int(a,16)^int(b,16))
'b922'
If the strings are not the same length, truncate the longer string to the length of the shorter using a slice longer = longer[:len(shorter)]
