In my case, I had copied some code from another project that was using Automapper - took me ages to work that one out. Just had to add automapper nuget package to project.
I think best approach until Angular team add this feature to cli is first create angular (ng new something) in other place and then add what you want to delete. Using git to check witch files are changed or added by angular cli. then you can revert that changes.
Be careful of untracked files from .gitignore
.
Apply these two things.
You need to set the character set of your database to be utf8
.
You need to call the mysql_set_charset('utf8')
in the file where you made the connection with the database and right after the selection of database like mysql_select_db
use the mysql_set_charset
. That will allow you to add and retrieve data properly in whatever the language.
We use a pretty convenient command line to force re-deployment of fresh images on integration pod.
We noticed that our alpine containers all run their "sustaining" command on PID 5. Therefore, sending it a SIGTERM
signal takes the container down. imagePullPolicy
being set to Always
has the kubelet re-pull the latest image when it brings the container back.
kubectl exec -i [pod name] -c [container-name] -- kill -15 5
You can try this:
.classname{_x000D_
width:250px;_x000D_
overflow:hidden;_x000D_
text-overflow:ellipsis;_x000D_
}
_x000D_
use agent detector and then with your web language create program to create css
for example in python
csscreator()
useragent = detector()
if useragent == "Firefox":
css = "your css"
...
return css
If using Vagrant try reloading your box. This solved my issue.
According to Extensible Messaging and Presence Protocol (Wikipedia), the standard TCP port for the server is 5222.
The client would presumably use the same ports as the messaging protocol, but can also use http (port 80) and https (port 443) for message delivery. These have the advantage of working for users behind firewalls, so your network admin should not need to get involved.
After some research, I've came up with the following code that should be the answer to your question. (At least it worked for me)
Use this piece of code first. The $(document).ready
makes sure the code is executed when the form is loaded into the DOM:
$(document).ready(function()
{
$('#theIdOfMyForm').submit(function(event){
if(!this.checkValidity())
{
event.preventDefault();
}
});
});
Then just call $('#theIdOfMyForm').submit();
in your code.
UPDATE
If you actually want to show which field the user had wrong in the form then add the following code after event.preventDefault();
$('#theIdOfMyForm :input:visible[required="required"]').each(function()
{
if(!this.validity.valid)
{
$(this).focus();
// break
return false;
}
});
It will give focus on the first invalid input.
This
var verificaHorario = $("#tbIntervalos").find("#" + horaInicial);
will find you the td that needs to be blocked.
Actually this will also do:
var verificaHorario = $("#" + horaInicial);
Testing for the size() of the wrapped set will answer your question regarding the existence of the id.
$(document).ready(function() {
$('a[data-toggle="tab"]').on( 'shown.bs.tab', function (e) {
// var target = $(e.target).attr("href"); // activated tab
// alert (target);
$($.fn.dataTable.tables( true ) ).css('width', '100%');
$($.fn.dataTable.tables( true ) ).DataTable().columns.adjust().draw();
} );
});
It works for me, with "autoWidth": false,
While you're waiting.. Curved corner (border-radius) cross browser
This also works.
fieldset {
width:0px;
}
Classes should avoid deriving from classes and instead implement the minimal interfaces necessary.
Deriving from classes breaks encapsulation:
Among other things this makes it harder to refactor your code.
Classes are an implementation detail that should be hidden from other parts of your code.
In short a System.List
is a specific implementation of an abstract data type, that may or may not be appropriate now and in the future.
Conceptually the fact that the System.List
data type is called "list" is a bit of a red-herring. A System.List<T>
is a mutable ordered collection that supports amortized O(1) operations for adding, inserting, and removing elements, and O(1) operations for retrieving the number of elements or getting and setting element by index.
When designing a data structure, the simpler the interface is, the more flexible the code is. Just look at how powerful LINQ is for a demonstration of this.
When you think "list" you should start by saying to yourself, "I need to represent a collection of baseball players". So let's say you decide to model this with a class. What you should do first is decide what the minimal amount of interfaces that this class will need to expose.
Some questions that can help guide this process:
IEnumerable<T>
IReadonlyList<T>
. ICollection<T>
ISet<T>
?IList<T>
. This way you will not be coupling other parts of the code to implementation details of your baseball players collection and will be free to change how it is implemented as long as you respect the interface.
By taking this approach you will find that code becomes easier to read, refactor, and reuse.
Implementing interfaces in a modern IDE should be easy. Right click and choose "Implement Interface". Then forward all of the implementations to a member class if you need to.
That said, if you find you are writing lots of boilerplate, it is potentially because you are exposing more functions than you should be. It is the same reason you shouldn't inherit from a class.
You can also design smaller interfaces that make sense for your application, and maybe just a couple of helper extension functions to map those interfaces to any others that you need. This is the approach I took in my own IArray
interface for the LinqArray library.
You can use jQuery's mouseenter and mouseleave events. You can set a flag when the mouse enters the desired area and unset the flag when it leaves the area.

I liked James Jenkins reply with the ISNULL check, but I think he meant IFNULL. ISNULL does not have a second parameter like his syntax, but IFNULL has the second parameter after the expression being checked to substitute if a NULL is found.

I decided, against my better judgment, to create a formula for Maven 3.1.1, which homebrew/versions
did not have. To do this:
homebrew/versions
on github.$(brew --prefix)/Library/Taps
to the local working copy of my fork. I'll call this my-homebrew/versions
.my-homebrew/versions/<formula>
.homebrew/versions
for my new formula.Yay.
You can use setScale() e.g.
double d = ...
BigDecimal db = new BigDecimal(d).setScale(12, BigDecimal.ROUND_HALF_UP);
If you need async: false
in your ajax, you should use success
instead of .done
. Else you better to use .done
.
This is from jQuery official site:
As of jQuery 1.8, the use of async: false with jqXHR ($.Deferred) is deprecated; you must use the success/error/complete callback options instead of the corresponding methods of the jqXHR object such as jqXHR.done().
Ajax is a way of using Javascript for communicating with serverside without loading the page over again. jQuery uses ajax for many of its functions, but it nothing else than a library that provides easier functionality.
With jQuery you dont have to think about creating xml objects ect ect, everything is done for you, but with straight up javascript ajax you need to program every single step of the ajax call.

sys.argv is a list containing the script path and command line arguments; i.e. sys.argv[0] is the path of the script you're running and all following members are arguments.
This is the answer, hope it helps someone :)
First there are two variations on how the xml can be written:
<row>
<IdInvernadero>8</IdInvernadero>
<IdProducto>3</IdProducto>
<IdCaracteristica1>8</IdCaracteristica1>
<IdCaracteristica2>8</IdCaracteristica2>
<Cantidad>25</Cantidad>
<Folio>4568457</Folio>
</row>
<row>
<IdInvernadero>3</IdInvernadero>
<IdProducto>3</IdProducto>
<IdCaracteristica1>1</IdCaracteristica1>
<IdCaracteristica2>2</IdCaracteristica2>
<Cantidad>72</Cantidad>
<Folio>4568457</Folio>
</row>
Answer:
SELECT
Tbl.Col.value('IdInvernadero[1]', 'smallint'),
Tbl.Col.value('IdProducto[1]', 'smallint'),
Tbl.Col.value('IdCaracteristica1[1]', 'smallint'),
Tbl.Col.value('IdCaracteristica2[1]', 'smallint'),
Tbl.Col.value('Cantidad[1]', 'int'),
Tbl.Col.value('Folio[1]', 'varchar(7)')
FROM @xml.nodes('//row') Tbl(Col)
<row IdInvernadero="8" IdProducto="3" IdCaracteristica1="8" IdCaracteristica2="8" Cantidad ="25" Folio="4568457" />
<row IdInvernadero="3" IdProducto="3" IdCaracteristica1="1" IdCaracteristica2="2" Cantidad ="72" Folio="4568457" />
Answer:
SELECT
Tbl.Col.value('@IdInvernadero', 'smallint'),
Tbl.Col.value('@IdProducto', 'smallint'),
Tbl.Col.value('@IdCaracteristica1', 'smallint'),
Tbl.Col.value('@IdCaracteristica2', 'smallint'),
Tbl.Col.value('@Cantidad', 'int'),
Tbl.Col.value('@Folio', 'varchar(7)')

I use this one-liner on my JasperServer Reports:
new SimpleDateFormat("yyyy-MM-dd").format(new SimpleDateFormat("yyyy-MM-dd").parse(new java.util.Date().format('yyyy') + "-" + (new Integer (new SimpleDateFormat("MM").format(new Date()))+1) + "-01")-1)
Doesn't look nice but works for me. Basically it's adding 1 to the current month, get the first day of that month and subtract one day.
I believe James Hunt's answer will solve the problem.
@user3731784: In your new message, the compiler seems to be confused because of the "C:\Program Files\IAR systems\Embedded Workbench 7.0\430\lib\dlib\d1430fn.h" argument. Why are you giving this header file at the middle of other compiler switches? Please correct this and try again. Also, it probably is a good idea to give the source file name after all the compiler switches and not at the beginning.
Try bellow code. This is help your code.
$("#btnUpdate").on("click", function () {
//alert("Alert Test");
var url = 'http://cooktv.sndimg.com/webcook/sandbox/perf/topics.json';
$.ajax({
type: "GET",
url: url,
data: "{}",
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (result) {
debugger;
$.each(result.callback, function (index, value) {
alert(index + ': ' + value.Name);
});
},
failure: function (result) { alert('Fail'); }
});
});
I could not access your url. Bellow error is shows
XMLHttpRequest cannot load http://cooktv.sndimg.com/webcook/sandbox/perf/topics.json. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:19829' is therefore not allowed access. The response had HTTP status code 501.
I use the following function to post data using curl. $data is an array of fields to post (will be correctly encoded using http_build_query). The data is encoded using application/x-www-form-urlencoded.
function httpPost($url, $data)
{
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($curl);
curl_close($curl);
return $response;
}
@Edward mentions that http_build_query may be omitted since curl will correctly encode array passed to CURLOPT_POSTFIELDS parameter, but be advised that in this case the data will be encoded using multipart/form-data.
I use this function with APIs that expect data to be encoded using application/x-www-form-urlencoded. That's why I use http_build_query().
as a noob using Python3 ,I find it might be an import error instead of a Django error
wrong:
from someModule import someClass
right:
from .someModule import someClass
this happens a few days ago but I really can't reproduce it...I think only people new to Django may encounter this.here's what I remember:
try to register a model in admin.py:
from django.contrib import admin
from user import User
admin.site.register(User)
try to run server, error looks like this
some lines...
File "/path/to/admin.py" ,line 6
tell you there is an import error
some lines...
Model class django.contrib.contenttypes.models.ContentType doesn't declare an explicit app_label
change user
to .user

So I made this ..kind of game.. based on this post (using msvcr library and Python 3.7).
The following is the "main function" of the game, that is detecting the keys pressed:
# Requiered libraries - - - -
import msvcrt
# - - - - - - - - - - - - - -
def _secret_key(self):
# Get the key pressed by the user and check if he/she wins.
bk = chr(10) + "-"*25 + chr(10)
while True:
print(bk + "Press any key(s)" + bk)
#asks the user to type any key(s)
kp = str(msvcrt.getch()).replace("b'", "").replace("'", "")
# Store key's value.
if r'\xe0' in kp:
kp += str(msvcrt.getch()).replace("b'", "").replace("'", "")
# Refactor the variable in case of multi press.
if kp == r'\xe0\x8a':
# If user pressed the secret key, the game ends.
# \x8a is CTRL+F12, that's the secret key.
print(bk + "CONGRATULATIONS YOU PRESSED THE SECRET KEYS!\a" + bk)
print("Press any key to exit the game")
msvcrt.getch()
break
else:
print(" You pressed:'", kp + "', that's not the secret key(s)\n")
if self.select_continue() == "n":
if self.secondary_options():
self._main_menu()
break
If you want the full source code of the porgram you can see it or download it from here:
(note: the secret keypress is: Ctrl+F12)
I hope you can serve as an example and help for those who come to consult this information.
I had similar problem with the data frame:
group time weight.loss
1 Control wl1 4.500000
2 Diet wl1 5.333333
3 DietEx wl1 6.200000
4 Control wl2 3.333333
5 Diet wl2 3.916667
6 DietEx wl2 6.100000
7 Control wl3 2.083333
8 Diet wl3 2.250000
9 DietEx wl3 2.200000
I think the variable for x axis should be numeric, so that geom_line knows how to connect the points to draw the line.
after I change the 2nd column to numeric:
group time weight.loss
1 Control 1 4.500000
2 Diet 1 5.333333
3 DietEx 1 6.200000
4 Control 2 3.333333
5 Diet 2 3.916667
6 DietEx 2 6.100000
7 Control 3 2.083333
8 Diet 3 2.250000
9 DietEx 3 2.200000
then it works.
Go to Help -> Install new softwares-> add -> paste this link in location box http://download.eclipse.org/webtools/repository/luna/ install all new versions..
Note that you could as well plot directly from ce
(after the comma removing) using the column name :
hist(ce$Weight)
(As opposed to using hist(ce[1])
, which would lead to the same "must be numeric" error.)
This also works for a database query result.
If the file exists and contains data, then it is possible to generate the fieldname

break
# add row to CSV file
with open(myFile, "a", newline='') as f:
writer = csv.DictWriter(f, fieldnames=header)
writer.writerow(myDict)

int [] v = Stream.of(line.split(",\\s+"))
.mapToInt(Integer::parseInt)
.toArray();
Bootstrap naming conventions carry styles of their own, col-XS-1 refers to a column being 8.33% of the containing element wide. Your text, would most likely expand far beyond the specified width, and couldn't possible be centered within it. If you wanted it to constrain to the div, you could use something like css word-break.
For centering the content within an element large enough to expand beyond the text, you have two options.
Option 1: HTML Center Tag
<div class="row">
<div class="col-xs-1 center-block">
<center>
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</center>
</div>
</div>
Option 2: CSS Text-Align
<div class="row">
<div class="col-xs-1 center-block" style="text-align:center;">
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</div>
</div>
If you wanted everything to constrain to the width of the column
<div class="row">
<div class="col-xs-1 center-block" style="text-align:center;word-break:break-all;">
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</div>
</div>
UPDATE - Using Bootstrap's text-center class
<div class="row">
<div class="col-xs-1 center-block text-center">
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</div>
</div>
FlexBox Method
<div class="row">
<div class="flexBox" style="
display: flex;
flex-flow: row wrap;
justify-content: center;">
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</div>
</div>
Using mysql CLI with -e option as Waverly360 suggests is a good one, but that might go out of memory and get killed on large results. (Havent find the reason behind it). If that is the case, and you need all records, my solution is: mysqldump + mysqldump2csv:
wget https://raw.githubusercontent.com/jamesmishra/mysqldump-to-csv/master/mysqldump_to_csv.py
mysqldump -u username -p --host=hostname database table | python mysqldump_to_csv.py > table.csv
You can use the following script, just replace DOMAIN with the name of your domain. When executed it will prompt you for a userlogin then hide that user's account from the address lists.

There is a pandas function that can be applied to DateTime index in pandas data frame.
date = dataframe.index #date is the datetime index
date = dates.strftime('%Y-%m-%d') #this will return you a numpy array, element is string.
dstr = date.tolist() #this will make you numpy array into a list
the element inside the list:
u'1910-11-02'
You might need to replace the 'u'.
There might be some additional arguments that I should put into the previous functions.
I work with CentOS 7 servers on which I don't have root access, nor git, svn, etc (nor want to!) so made a python script to download any github folder: https://github.com/andrrrl/github-folder-downloader
Usage is simple, just copy the relevant part from a github project, let's say the project is https://github.com/MaxCDN/php-maxcdn/, and you want a folder where some source files are only, then you need to do something like:
$ python gdownload.py "/MaxCDN/php-maxcdn/tree/master/src" /my/target/dir/
(will create target folder if doesn't exist)
It requires lxml library, can be installed with easy_install lxml
If you don't have root access (like me) you can create a .pydistutils.py
file into your $HOME
dir with these contents:
[install]
user=1
And easy_install lxml
will just work (ref: https://stackoverflow.com/a/33464597/591257).
Like this:
String[][] arrays = { array1, array2, array3, array4, array5 };
or
String[][] arrays = new String[][] { array1, array2, array3, array4, array5 };
(The latter syntax can be used in assignments other than at the point of the variable declaration, whereas the shorter syntax only works with declarations.)
In my opinion the best approach to achieve this by using the filter
method as it's meaningless to return in a forEach
block; for an example on your snippet:
// Fetch all objects in SomeElements collection
var elementsCollection = SomeElements.find();
elementsCollection
.filter(function(element) {
return element.shouldBeProcessed;
})
.forEach(function(element){
doSomeLengthyOperation();
});
This will narrow down your elementsCollection
and just keep the filtred
elements that should be processed.
As far as the Markdown syntax is concerned, if you want to get that detailed, you'll just have to use HTML.
<a href="http://example.com/" target="_blank">Hello, world!</a>
Most Markdown engines I've seen allow plain old HTML, just for situations like this where a generic text markup system just won't cut it. (The StackOverflow engine, for example.) They then run the entire output through an HTML whitelist filter, regardless, since even a Markdown-only document can easily contain XSS attacks. As such, if you or your users want to create _blank
links, then they probably still can.
If that's a feature you're going to be using often, it might make sense to create your own syntax, but it's generally not a vital feature. If I want to launch that link in a new window, I'll ctrl-click it myself, thanks.
here's one i just wrote, maybe it's not as optimized (just uses a sorted dictionary) but simple to understand. you can insert objects of different kinds, so no generic queues.

Active Directory is a super-set of the LDAP protocol. Depending on how the organization uses Active Directory, your LDAP search/set queries may or may not work.
In website panels like cPanel you may add a single %
(percentage sign) in allowed hostnames to access your MySQL database.
By adding a single %
you can access your database from any IP or website even from desktop applications.
did you try 'git add .' . will it all the changes? (you can remove unnecessary added files by git reset HEAD )
If you want to scroll down to the div (id="div1"). Then you can use this code.
$('html, body').animate({
scrollTop: $("#div1").offset().top
}, 1500);
Entire request and response is encrypted, including URL.
Note that when you use a HTTP Proxy, it knows the address (domain) of the target server, but doesn't know the requested path on this server (i.e. request and response are always encrypted).
JNDI needs to be approached with the understanding that it is a service locator. When the desired service is hosted on the same server/node as the application, then your use of InitialContext may work.
What makes it more complicated is that defining a Data Source in Web Sphere (at least back in 4.0) allowed you to define the visibility to various degrees. Basically it adds namespaces to the environment and clients have to know where the resource is hosted.
javax.naming.InitialContext ctx = new javax.naming.InitialContext();
DataSource ds = (DataSource) ctx.lookup("java:comp/env/DataSourceAlias");
Here is IBM's reference page.
If you are trying to reference a data source from an app that is NOT in the J2EE container, you'll need a slightly different approach starting with needing some J2EE client jars in your classpath. http://www.coderanch.com/t/75386/Websphere/lookup-datasources-JNDI-outside-EE
So, we have a situation when we need to statically get class object or a class full/simple name without an explicit usage of MyClass.class
syntax.
It can be really handy in some cases, e.g. logger instance for the kotlin upper-level functions (in this case kotlin creates a static Java class not accessible from the kotlin code).
We have a few different variants for getting this info:
new Object(){}.getClass().getEnclosingClass();
noted by Tom Hawtin - tackline
getClassContext()[0].getName();
from the SecurityManager
noted by Christoffer
new Throwable().getStackTrace()[0].getClassName();
by count ludwig
Thread.currentThread().getStackTrace()[1].getClassName();
from Keksi
and finally awesome
MethodHandles.lookup().lookupClass();
from Rein
I've prepared a jmh benchmark for all variants and results are:
# Run complete. Total time: 00:04:18
Benchmark Mode Cnt Score Error Units
StaticClassLookup.MethodHandles_lookup_lookupClass avgt 30 3.630 ± 0.024 ns/op

MethodHandles.lookup().lookupClass();
new Object(){}.getClass().getEnclosingClass();
If you need it in many places and don't want your bytecode to bloat due to tons of anonymous classes – SecurityManager
is your friend (third best option).
But you can't just call getClassContext()
– it's protected in the SecurityManager
class. You will need some helper class like this:
// Helper class
public final class CallerClassGetter extends SecurityManager
{
private static final CallerClassGetter INSTANCE = new CallerClassGetter();
private CallerClassGetter() {}
public static Class<?> getCallerClass() {
return INSTANCE.getClassContext()[1];
}
}
// Usage example:
class FooBar
{
static final Logger LOGGER = LoggerFactory.getLogger(CallerClassGetter.getCallerClass())
}
getStackTrace()
from exception or the Thread.currentThread()
. Very inefficient and can return only the class name as a String
, not the Class<*>
instance.If you want to create a logger instance for static kotlin utils (like me :), you can use this helper:
import org.slf4j.Logger
import org.slf4j.LoggerFactory
// Should be inlined to get an actual class instead of the one where this helper declared
// Will work only since Java 7 and Android API 26!
@Suppress("NOTHING_TO_INLINE")
inline fun loggerFactoryStatic(): Logger
= LoggerFactory.getLogger(MethodHandles.lookup().lookupClass())
Usage example:
private val LOGGER = loggerFactoryStatic()
/**
* Returns a pseudo-random, uniformly distributed value between the
* given least value (inclusive) and bound (exclusive).
*
* @param min the least value returned
* @param max the upper bound (exclusive)
*
* @return the next value
* @throws IllegalArgumentException if least greater than or equal to bound
* @see java.util.concurrent.ThreadLocalRandom.nextDouble(double, double)
*/
fun Random.nextDouble(min: Double = .0, max: Double = 1.0): Double {
if (min >= max) {
if (min == max) return max
LOGGER.warn("nextDouble: min $min > max $max")
return min
}
return nextDouble() * (max - min) + min
}
The ALTER TABLE
MySQL command should do the trick. The following command will change the default character set of your table and the character set of all its columns to UTF8.
ALTER TABLE etape_prospection CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
This command will convert all text-like columns in the table to the new character set. Character sets use different amounts of data per character, so MySQL will convert the type of some columns to ensure there's enough room to fit the same number of characters as the old column type.
I recommend you read the ALTER TABLE MySQL documentation before modifying any live data.
If you want to compare dates and not time, you could use this:
$d1->format("Y-m-d") == $d2->format("Y-m-d")
Another approach is to wrap your table in a scrollable element and set the header cells to stick to the top.
The advantage of this approach is that you don't have to change the display on tbody and you can leave it to the browser to calculate column width while keeping the header cell widths in line with the data cell column widths.

If it's a File, you can get the parts by creating an instanceof File and then ask for its segments.
This is good because it'll work regardless of the direction of the slashes; it's platform independent (except for the "drive letters" in windows...)
$unixtime = 1307595105;
echo $time = date("m/d/Y h:i:s A T",$unixtime);
Where
In it's simplest form you would use it like:
var html = _.template('<li><%= name %></li>', { name: 'John Smith' });
//html is now '<li>John Smith</li>'
If you're going to be using a template a few times you'll want to compile it so it's faster:
var template = _.template('<li><%= name %></li>');
var html = [];
for (var key in names) {
html += template({ name: names[i] });
}
console.log(html.join('')); //Outputs a string of <li> items
I personally prefer the Mustache style syntax. You can adjust the template token markers to use double curly braces:
_.templateSettings.interpolate = /\{\{(.+?)\}\}/g;
var template = _.template('<li>{{ name }}</li>');
http://wxcode.sourceforge.net/docs/wxpdfdoc/
Works with the wxWidgets library.
I have this array as my request data from a HTML+Vue.js data grid/table:
[0] => Array
(
[item_id] => 1
[item_no] => 3123
[size] => 3e
)
[1] => Array
(
[item_id] => 2
[item_no] => 7688
[size] => 5b
)
And use this to validate which works properly:
$this->validate($request, [
'*.item_id' => 'required|integer',
'*.item_no' => 'required|integer',
'*.size' => 'required|max:191',
]);
The reason IMHO is because they are/were too lazy to implement/correct that mistake. Suggesting that C/C++ programmers does not understand unsigned, structure, union, bit flag... Is just preposterous.
Ether you were talking with a basic/bash/java programmer on the verge of beginning programming a la C, without any real knowledge this language or you are just talking out of your own mind. ;)
when you deal every day on format either from file or hardware you begin to question, what in the hell they were thinking.
A good example here would be trying to use an unsigned byte as a self rotating loop. For those of you who do not understand the last sentence, how on earth you call yourself a programmer.

Option 3
To update current iframe
$("iframe").wrap('<div class="embed-responsive embed-responsive-16by9"/>');
$("iframe").addClass('embed-responsive-item');
I have accomplished this with a hidden iframe. I use perl, not php, so will just give concept, not code solution.
Client sends Ajax request to server, causing the file content to be generated. This is saved as a temp file on the server, and the filename is returned to the client.
Client (javascript) receives filename, and sets the iframe src to some url that will deliver the file, like:
$('iframe_dl').src="/app?download=1&filename=" + the_filename
Server slurps the file, unlinks it, and sends the stream to the client, with these headers:
Content-Type:'application/force-download'
Content-Disposition:'attachment; filename=the_filename'
Works like a charm.
You can use - desc / to see the view/table definition in Redshift. I have been using Workbench/J as a SQL client for Redshift and it gives the definition in the Messages tab adjacent to Result tab.
This question is very similar to this one...
You need to force the cache to expire for this to work. Place the following code on your page code behind.
Page.Response.Cache.SetCacheability(HttpCacheability.NoCache)
res.send()
will send the HTTP response. Its syntax is,
res.send([body])
The body parameter can be a Buffer object, a String, an object, or an Array. For example:
res.send(new Buffer('whoop'));
res.send({ some: 'json' });
res.send('<p>some html</p>');
res.status(404).send('Sorry, we cannot find that!');
res.status(500).send({ error: 'something blew up' });
See this for more info.
res.end()
will end the response process. This method actually comes from Node core, specifically the response.end()
method of http.ServerResponse
. It is used to quickly end the response without any data. For example:
res.end();
res.status(404).end();
Read this for more info.
The T
doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time.
The Z
stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).
Both characters are just static letters in the format, which is why they are not documented by the datetime.strftime()
method. You could have used Q
or M
or Monty Python
and the method would have returned them unchanged as well; the method only looks for patterns starting with %
to replace those with information from the datetime
object.
You can use .loc
to select the specific columns with all rows and then pull that. An example is below:
pandas.merge(dataframe1, dataframe2.iloc[:, [0:5]], how='left', on='key')
In this example, you are merging dataframe1 and dataframe2. You have chosen to do an outer left join on 'key'. However, for dataframe2 you have specified .iloc
which allows you to specific the rows and columns you want in a numerical format. Using :
, your selecting all rows, but [0:5]
selects the first 5 columns. You could use .loc
to specify by name, but if your dealing with long column names, then .iloc
may be better.
To create your cell styles see: http://poi.apache.org/spreadsheet/quick-guide.html#CustomColors.
Custom colors
HSSF:
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet();
HSSFRow row = sheet.createRow((short) 0);
HSSFCell cell = row.createCell((short) 0);
cell.setCellValue("Default Palette");
//apply some colors from the standard palette,
// as in the previous examples.
//we'll use red text on a lime background
HSSFCellStyle style = wb.createCellStyle();
style.setFillForegroundColor(HSSFColor.LIME.index);
style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
HSSFFont font = wb.createFont();
font.setColor(HSSFColor.RED.index);
style.setFont(font);
cell.setCellStyle(style);
//save with the default palette
FileOutputStream out = new FileOutputStream("default_palette.xls");
wb.write(out);
out.close();
//now, let's replace RED and LIME in the palette
// with a more attractive combination
// (lovingly borrowed from freebsd.org)
cell.setCellValue("Modified Palette");
//creating a custom palette for the workbook
HSSFPalette palette = wb.getCustomPalette();
//replacing the standard red with freebsd.org red
palette.setColorAtIndex(HSSFColor.RED.index,
(byte) 153, //RGB red (0-255)
(byte) 0, //RGB green
(byte) 0 //RGB blue
);
//replacing lime with freebsd.org gold
palette.setColorAtIndex(HSSFColor.LIME.index, (byte) 255, (byte) 204, (byte) 102);
//save with the modified palette
// note that wherever we have previously used RED or LIME, the
// new colors magically appear
out = new FileOutputStream("modified_palette.xls");
wb.write(out);
out.close();
XSSF:
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sheet = wb.createSheet();
XSSFRow row = sheet.createRow(0);
XSSFCell cell = row.createCell( 0);
cell.setCellValue("custom XSSF colors");
XSSFCellStyle style1 = wb.createCellStyle();
style1.setFillForegroundColor(new XSSFColor(new java.awt.Color(128, 0, 128)));
style1.setFillPattern(CellStyle.SOLID_FOREGROUND);
Class.getResource
can take a "relative" resource name, which is treated relative to the class's package. Alternatively you can specify an "absolute" resource name by using a leading slash. Classloader resource paths are always deemed to be absolute.
So the following are basically equivalent:
foo.bar.Baz.class.getResource("xyz.txt");
foo.bar.Baz.class.getClassLoader().getResource("foo/bar/xyz.txt");
And so are these (but they're different from the above):
foo.bar.Baz.class.getResource("/data/xyz.txt");
foo.bar.Baz.class.getClassLoader().getResource("data/xyz.txt");
<script>
window.fbAsyncInit = function() {
FB.init({
appId :'your-app-id',
xfbml :true,
version :'v2.1'
});
};
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if(d.getElementById(id)) {
return;
}
js = d.createElement(s);
js.id = id;
js.src ="// connect.facebook.net/en_US /sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}
(document,'script','facebook-jssdk'));
</script>
From the documentation: The Facebook SDK for JavaScript doesn't have any standalone files that need to be downloaded or installed, instead you simply need to include a short piece of regular JavaScript in your HTML tha
To call the function on click of some html element (control).
$('#controlID').click(myFunction);
You will need to ensure you bind the event when your html element is ready on which you binding the event. You can put the code in document.ready
$(document).ready(function(){
$('#controlID').click(myFunction);
});
You can use anonymous function to bind the event to the html element.
$(document).ready(function(){
$('#controlID').click(function(){
$.messager.show({
title:'My Title',
msg:'The message content',
showType:'fade',
style:{
right:'',
bottom:''
}
});
});
});
If you want to bind click with many elements you can use class selector
$('.someclass').click(myFunction);
Edit based on comments by OP, If you want to call function under some condition
You can use if for conditional execution, for example,
if(a == 3)
myFunction();
Use ThenBy
:
var orderedCustomers = Customer.OrderBy(c => c.LastName).ThenBy(c => c.FirstName)
See MSDN: http://msdn.microsoft.com/en-us/library/bb549422.aspx
If you are looking for a solution that works in IE as well, you could float the list elements to the left. However, this will result in a list that snakes around, like this:
item 1 | item 2 | item 3
item 4 | item 5
Instead of neat columns, like:
item 1 | item 4
item 2 |
item 3 |
The code to do that would be:
ul li {
width:10em;
float:left;
}
You could add a border-bottom to the li
s to make the flow of the items from left to right more apparent.
If you truly want to confirm that a variable is not null and not an empty string specifically, you would write:
if(data !== null && data !== '') {
// do something
}
Notice that I changed your code to check for type equality (!==
|===
).
If, however you just want to make sure, that a code will run only for "reasonable" values, then you can, as others have stated already, write:
if (data) {
// do something
}
Since, in javascript, both null values, and empty strings, equals to false (i.e. null == false
).
The difference between those 2 parts of code is that, for the first one, every value that is not specifically null or an empty string, will enter the if
. But, on the second one, every true-ish value will enter the if
: false
, 0
, null
, undefined
and empty strings, would not.
No such thing. the input type=date
will pick up whatever your system default is and show that in the GUI but will always store the value in ISO format (yyyy-mm-dd). Beside be aware that not all browsers support this so it's not a good idea to depend on this input type yet.
If this is a corporate issue, force all the computer to use local regional format (dd-mm-yyyy) and your UI will show it in this format (see wufoo link before after changing your regional settings, you need to reopen the browser).
See: http://www.wufoo.com/html5/types/4-date.html for example
See: http://caniuse.com/#feat=input-datetime for browser supports
See: https://www.w3.org/TR/2011/WD-html-markup-20110525/input.date.html for spec. <- no format attr.
Your best bet is still to use JavaScript based component that will allow you to customize this to whatever you wish.
What you need is a split user-defined function. With that, the solution looks like
With SplitValues As
(
Select T.Name, Z.Position, Z.Value
, Row_Number() Over ( Partition By T.Name Order By Z.Position ) As Num
From Table As T
Cross Apply dbo.udf_Split( T.Name, ' ' ) As Z
)
Select Name
, FirstName.Value
, Case When ThirdName Is Null Then SecondName Else ThirdName End As LastName
From SplitValues As FirstName
Left Join SplitValues As SecondName
On S2.Name = S1.Name
And S2.Num = 2
Left Join SplitValues As ThirdName
On S2.Name = S1.Name
And S2.Num = 3
Where FirstName.Num = 1
Here's a sample split function:
Create Function [dbo].[udf_Split]
(
@DelimitedList nvarchar(max)
, @Delimiter nvarchar(2) = ','
)
RETURNS TABLE
AS
RETURN
(
With CorrectedList As
(
Select Case When Left(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
+ @DelimitedList
+ Case When Right(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
As List
, Len(@Delimiter) As DelimiterLen
)
, Numbers As
(
Select TOP( Coalesce(DataLength(@DelimitedList)/2,0) ) Row_Number() Over ( Order By c1.object_id ) As Value
From sys.columns As c1
Cross Join sys.columns As c2
)
Select CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen As Position
, Substring (
CL.List
, CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen
, CharIndex(@Delimiter, CL.list, N.Value + 1)
- ( CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen )
) As Value
From CorrectedList As CL
Cross Join Numbers As N
Where N.Value <= DataLength(CL.List) / 2
And Substring(CL.List, N.Value, CL.DelimiterLen) = @Delimiter
)
There are no limits to the number of objects you can store in your S3 bucket. AWS claims it to have unlimited storage. However, there are some limitations -
That being said if you really have a lot of objects to be stored in S3 bucket consider randomizing your object name prefix to improve performance.
When your workload is a mix of request types, introduce some randomness to key names by adding a hash string as a prefix to the key name. By introducing randomness to your key names the I/O load will be distributed across multiple index partitions. For example, you can compute an MD5 hash of the character sequence that you plan to assign as the key and add 3 or 4 characters from the hash as a prefix to the key name.

Apache CXF will pretty print XML messages formatting them with proper indentation and line breaks. Very useful. More about it here.
Sometimes we have to work with ThirdParty controls and we need to build these awkward solutions. Based in @Anoop Muraleedharan answer I created this solution with inference type and ToolStripItem support
public static void RemoveItemEvents<T>(this T target, string eventName)
where T : ToolStripItem
{
RemoveObjectEvents<T>(target, eventName);
}
public static void RemoveControlEvents<T>(this T target, string eventName)
where T : Control
{
RemoveObjectEvents<T>(target, eventName);
}
private static void RemoveObjectEvents<T>(T target, string Event) where T : class
{
var typeOfT = typeof(T);
var fieldInfo = typeOfT.BaseType.GetField(
Event, BindingFlags.Static | BindingFlags.NonPublic);
var provertyValue = fieldInfo.GetValue(target);
var propertyInfo = typeOfT.GetProperty(
"Events", BindingFlags.NonPublic | BindingFlags.Instance);
var eventHandlerList = (EventHandlerList)propertyInfo.GetValue(target, null);
eventHandlerList.RemoveHandler(provertyValue, eventHandlerList[provertyValue]);
}
And you can use it like this
var toolStripButton = new ToolStripButton();
toolStripButton.RemoveItemEvents("EventClick");
var button = new Button();
button.RemoveControlEvents("EventClick");
You want the datetime module.
>>> from datetime import datetime, timedelta
>>> datetime(2008,08,18) - datetime(2008,09,26)
datetime.timedelta(4)
Another example:
>>> import datetime
>>> today = datetime.date.today()
>>> print(today)
2008-09-01
>>> last_year = datetime.date(2007, 9, 1)
>>> print(today - last_year)
366 days, 0:00:00
As pointed out here
>>> import datetime
>>> d = datetime.datetime.strptime('2011-06-09', '%Y-%m-%d')
>>> d.strftime('%b %d,%Y')
'Jun 09,2011'
In pre-2.5 Python, you can replace datetime.strptime
with time.strptime
, like so (untested): datetime.datetime(*(time.strptime('2011-06-09', '%Y-%m-%d')[0:6]))
This is the simplest way to check if a file exists. Just because the file existed when you checked doesn't guarantee that it will be there when you need to open it.
import os
fname = "foo.txt"
if os.path.isfile(fname):
print("file does exist at this time")
else:
print("no such file exists at this time")
Another alternative is to use sdkman. An advantage of sdkman over brew is that many versions of gradle are supported. (brew only supports the latest version and 2.14.) To install sdkman execute:
curl -s "https://get.sdkman.io" | bash
Then follow the instructions. Go here for more installation information. Once sdkman is installed use the command:
sdk install gradle
Or to install a specific version:
sdk install gradle 2.2
Or use to use a specific installed version:
sdk use gradle 2.2
To see which versions are installed and available:
sdk list gradle
For more information go here.
<form id="myform">
<input type="textbox" id="field"/>
<input type="button" value="submit">
</form>
<script>
$(function () {
$("#field").keyup(function (event) {
if (event.which === 13) {
document.myform.submit();
}
}
});
</script>
You can convert your number to string and use list slicing like this:
int(str(number)[:2])
Output:
>>> number = 1520
>>> int(str(number)[:2])
15
I know this is an older question, but I wanted to post an answer for users with the same question:
curl -H 'Cache-Control: no-cache' http://www.example.com
This curl command servers in its header request to return non-cached data from the web server.
In "Path" variable removed "C:\ProgramData\Oracle\Java\javapath" and replaced it with "C:\Program Files\Java\jdk1.8.0_212\bin"
It worked for me.

You need to store the psftp script (lines from open
to bye
) into a separate file and pass that to psftp
using -b
switch:
cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"
Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b
EDIT: For username+password: As you cannot use psftp
commands in a batch file, for the same reason, you cannot specify the username and the password as psftp
commands. These are inputs to the open
command. While you can specify the username with the open
command (open <user>@<IP>
), you cannot specify the password this way. This can be done on a psftp
command line only. Then it's probably cleaner to do all on the command-line:
cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>
And remove the open
, <user>
and <PW>
lines from your script.txt
.
Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-starting
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-pw
What you are doing atm is that you run psftp
without any parameter or commands. Once you exit it (like by typing bye
), your batch file continues trying to run open
command (and others), what Windows shell obviously does not understand.
If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:
(
echo cd ...
echo lcd ...
echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>
Preventing XSS is a different issue from validating input.
Regarding XSS: You should not try to check input for XSS or related exploits. You should prevent XSS exploits, SQL injection and so on by escaping correctly when inserting strings into a different language where some characters are "magic", eg, when inserting strings in HTML or SQL. For example a name like O'Reilly is perfectly valid input, but could cause a crash or worse if inserted unescaped into SQL. You cannot prevent that kind of problems by validating input.
Validation of user input makes sense to prevent missing or malformed data, eg. a user writing "asdf" in the zip-code field and so on. Wrt. e-mail adresses, the syntax is so complex though, that it doesnt provide much benefit to validate it using a regex. Just check that it contains a "@".
Push a new page onto the stack, then remove the current page. This results in a switch.
item.Tapped += async (sender, e) => {
await Navigation.PushAsync (new SecondPage ());
Navigation.RemovePage(this);
};
You need to be in a Navigation Page first:
MainPage = NavigationPage(new FirstPage());
Switching content isn't ideal as you have just one big page and one set of page events like OnAppearing ect.
As far as I can see in the manual, it is not possible to call functions inside HEREDOC strings. A cumbersome way would be to prepare the words beforehand:
<?php
$world = _("World");
$str = <<<EOF
<p>Hello</p>
<p>$world</p>
EOF;
echo $str;
?>
a workaround idea that comes to mind is building a class with a magic getter method.
You would declare a class like this:
class Translator
{
public function __get($name) {
return _($name); // Does the gettext lookup
}
}
Initialize an object of the class at some point:
$translate = new Translator();
You can then use the following syntax to do a gettext lookup inside a HEREDOC block:
$str = <<<EOF
<p>Hello</p>
<p>{$translate->World}</p>
EOF;
echo $str;
?>
$translate->World
will automatically be translated to the gettext lookup thanks to the magic getter method.
To use this method for words with spaces or special characters (e.g. a gettext entry named Hello World!!!!!!
, you will have to use the following notation:
$translate->{"Hello World!!!!!!"}
This is all untested but should work.
Update: As @mario found out, it is possible to call functions from HEREDOC strings after all. I think using getters like this is a sleek solution, but using a direct function call may be easier. See the comments on how to do this.
You can access you website using your IP address and your cPanel username with ~ symbols. For Example: http://serverip/~cpusername like as https://xxx.xxx.xx.xx/~mohidul
There's also MSMQ (Microsoft Message Queueing) which can operate across networks as well as on a local computer. Although there are better ways to communicate it's worth looking into: https://msdn.microsoft.com/en-us/library/ms711472(v=vs.85).aspx
You can set the color of a JLabel by altering the foreground category:
JLabel title = new JLabel("I love stackoverflow!", JLabel.CENTER);
title.setForeground(Color.white);
As far as I know, the simplest way to create the two-color label you want is to simply make two labels, and make sure they get placed next to each other in the proper order.
Suppose you have a table employee
, with the following columns:
employee (first_name, last_name, start_date)
In order to delete the rows with a duplicate first_name
column:
delete
from employee using employee,
employee e1
where employee.id > e1.id
and employee.first_name = e1.first_name
Might not be exactly what the OP was looking for, but this page is where I found myself after looking for the problem, so sharing this for everyone with similar issue :)
Stack's fit
property did the trick for my needs. Otherwise Image inside (OctoImageIn my case) was padded and providing other Image.fit
values did not give any effect.
Stack(
fit: StackFit.expand,
children: [
Image(
image: provider,
fit: BoxFit.cover,
),
// other irrelevent children here
]
);
>>> points = {'a': (3, 4), 'c': (5, 5), 'b': (1, 2), 'd': (3, 3)}
>>> dict(filter(lambda x: (x[1][0], x[1][1]) < (5, 5), points.items()))
{'a': (3, 4), 'b': (1, 2), 'd': (3, 3)}
I kind of like this solution :
: `particular_script`
The command/script between the back ticks is executed and its output is fed to the command ":" (which is the equivalent of "true")
$ false
$ echo $?
1
$ : `false`
$ echo $?
0

Unfortunately, crontabs have a very limited environment variables scope, thus you need to export them every time the corntab runs.
An easy approach would be the following example, suppose you've your env vars in a file called env, then:
* * * * * . ./env && /path/to_your/command
this part . ./env
will export them and then they're used within the same scope of your command
AkashG's solution don't work for me. When I set up check.xml to background it's just stratched in vertical direction. To solve this problem you should set up check.xml to "android:button" property:
<ToggleButton
android:id="@+id/toggle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@drawable/check" //check.xml
android:background="@null"/>
check.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected, use grey -->
<item android:drawable="@drawable/selected_image"
android:state_checked="true" />
<!-- When not selected, use white-->
<item android:drawable="@drawable/unselected_image"
android:state_checked="false"/>
</selector>
If you want to detach existing object follow @Slauma's advice. If you want to load objects without tracking changes use:
var data = context.MyEntities.AsNoTracking().Where(...).ToList();
As mentioned in comment this will not completely detach entities. They are still attached and lazy loading works but entities are not tracked. This should be used for example if you want to load entity only to read data and you don't plan to modify them.
I use the reflections in the toString() implementation of my preference class to see the class members and values (simple and quick debugging).
The simplified code I'm using:
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
Class<?> thisClass = null;
try {
thisClass = Class.forName(this.getClass().getName());
Field[] aClassFields = thisClass.getDeclaredFields();
sb.append(this.getClass().getSimpleName() + " [ ");
for(Field f : aClassFields){
String fName = f.getName();
sb.append("(" + f.getType() + ") " + fName + " = " + f.get(this) + ", ");
}
sb.append("]");
} catch (Exception e) {
e.printStackTrace();
}
return sb.toString();
}
I hope that it will help someone, because I also have searched.
Consideration must also be given to your individual FPM pools, if any.
I couldn't figure out why none of these answers was working for me today. This had been a set-and-forget scenario for me, where I had forgotten that listen.user and listen.group were duplicated on a per-pool basis.
If you used pools for different user accounts like I did, where each user account owns their FPM processes and sockets, setting only the default listen.owner and listen.group configuration options to 'nginx' will simply not work. And obviously, letting 'nginx' own them all is not acceptable either.
For each pool, make sure that
listen.group = nginx
Otherwise, you can leave the pool's ownership and such alone.
From React's documentation:
setState()
does not immediately mutatethis.state
but creates a pending state transition. Accessingthis.state
after calling this method can potentially return the existing value. There is no guarantee of synchronous operation of calls tosetState
and calls may be batched for performance gains.
If you want a function to be executed after the state change occurs, pass it in as a callback.
this.setState({value: event.target.value}, function () {
console.log(this.state.value);
});
This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.
MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
headers);
JSONObject jsonObject = null;
try {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> responseEntity = restTemplate.exchange(
"https://url", HttpMethod.POST, entity,
String.class);
if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
try {
jsonObject = new JSONObject(responseEntity.getBody());
} catch (JSONException e) {
throw new RuntimeException("JSONException occurred");
}
}
} catch (final HttpClientErrorException httpClientErrorException) {
throw new ExternalCallBadRequestException();
} catch (HttpServerErrorException httpServerErrorException) {
throw new ExternalCallServerErrorException(httpServerErrorException);
} catch (Exception exception) {
throw new ExternalCallServerErrorException(exception);
}
ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.
Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

These answers, including the selected answer, are good for introducing promises conceptually, but lacking in specifics of what exactly the differences are in the terminology that arises when using libraries implementing them (and there are important differences).
Since it is still an evolving spec, the answer currently comes from attempting to survey both references (like wikipedia) and implementations (like jQuery):
Deferred: Never described in popular references,
1
2
3
4
but commonly used by implementations as the arbiter of promise resolution (implementing resolve
and reject
).
5
6
7
Sometimes deferreds are also promises (implementing then
),
5
6
other times it's seen as more pure to have the Deferred only
capable of resolution, and forcing the user to access the promise for
using then
.
7
Promise: The most all-encompasing word for the strategy under discussion.
A proxy object storing the result of a target function whose
synchronicity we would like to abstract, plus exposing a then
function
accepting another target function and returning a new promise.
2
Example from CommonJS:
> asyncComputeTheAnswerToEverything()
.then(addTwo)
.then(printResult);
44
Always described in popular references, although never specified as to whose responsibility resolution falls to. 1 2 3 4
Always present in popular implementations, and never given resolution abilites. 5 6 7
Future: a seemingly deprecated term found in some popular references 1 and at least one popular implementation, 8 but seemingly being phased out of discussion in preference for the term 'promise' 3 and not always mentioned in popular introductions to the topic. 9
However, at least one library uses the term generically for abstracting
synchronicity and error handling, while not providing then
functionality.
10
It's unclear if avoiding the term 'promise' was intentional, but probably a
good choice since promises are built around 'thenables.'
2
Difference between Promises/A and Promises/A+
(TL;DR, Promises/A+ mostly resolves ambiguities in Promises/A)
You could use a classmethod
or staticmethod
class Paul(object):
elems = []
@classmethod
def addelem(cls, e):
cls.elems.append(e)
@staticmethod
def addelem2(e):
Paul.elems.append(e)
Paul.addelem(1)
Paul.addelem2(2)
print(Paul.elems)
classmethod
has advantage that it would work with sub classes, if you really wanted that functionality.
module is certainly best though.
Several people seem to have the same problem. The issue is that the IDE only displays the preview if editing a layout file in the res/layout*
directory of an Android project.
In particular, it won't show if editing a file in build/res/layout*
since those are not source directory but output directory. In your case, you are editing a file in the build/
directory...
The Resource folder is set automatically, and can be viewed (and changed) in Project Structure > Modules > [Module name] > Android > Resources directory.
You want to feed the create.sql

I was having this problem but i found out that it was a permissions problem I changed my permissions to 0744 and now it works. I don't know if this was your problem but it worked for me.
Assuming such a query would return a single row, you could use either
select @EmpId = Id from dbo.Employee
Or
set @EmpId = (select Id from dbo.Employee)
If I am not mistaken, it will be onunload event.
"Occurs when the application is about to be unloaded." - MSDN
They're actually the same. There's one difference I can see. With Application class you can initialize your variables in Application.onCreate() and destroy them in Application.onTerminate(). With singleton you have to rely VM initializing and destroying statics.
OpenSSL command line app does not display any characters when you are entering your password. Just type it then press enter and you will see that it is working.
You can also use openssl pkcs12 -export -inkey mykey.key -in developer_identity.pem -out iphone_dev.p12 -password pass:YourPassword
to pass the password YourPassword
from command line. Please take a look at section Pass Phrase Options in OpenSSL manual for more information.

ALTER SCHEMA TargetSchema
TRANSFER SourceSchema.TableName;

stored procedure:
exec sp_MSforeachtable "ALTER SCHEMA TargetSchema TRANSFER ?"

Not particularly easily- if you've lost the pointer to the tip of a branch, it's rather like finding a needle in a haystack. You can find all the commits that don't appear to be referenced any more- git fsck --unreachable
will do this for you- but that will include commits that you threw away after a git commit --amend
, old commits on branches that you rebased etc etc. So seeing all these commits at once is quite likely far too much information to wade through.
So the flippant answer is, don't lose track of things you're interested in. More seriously, the reflogs will hold references to all the commits you've used for the last 60 days or so by default. More importantly, they will give some context about what those commits are.
If you like
var response = '{"result":true,"count":1}';
var JsonObject= JSON.parse(response);
you can access the JSON elements by JsonObject with (.) dot:
JsonObject.result;
JsonObject.count;
If you are using the animation listener, set v.setAnimationListener(null)
. Use the following code with all options.
v.getAnimation().cancel();
v.clearAnimation();
animation.setAnimationListener(null);
The os.makedirs
function does this. Try the following:
import os
import errno
filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
try:
os.makedirs(os.path.dirname(filename))
except OSError as exc: # Guard against race condition
if exc.errno != errno.EEXIST:
raise
with open(filename, "w") as f:
f.write("FOOBAR")
The reason to add the try-except
block is to handle the case when the directory was created between the os.path.exists
and the os.makedirs
calls, so that to protect us from race conditions.
In Python 3.2+, there is a more elegant way that avoids the race condition above:
import os
filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
f.write("FOOBAR")
there is no need to js or jquery. to stop page reloading just specify the button type as 'button'. if you dont specify the button type, browser will set it to 'reset' or 'submit' witch cause to page reload.
<button type='button'>submit</button>
I am using version 4.0.6 ( the current release) on Linux Mint. You need to install Mongodb Compass(mongodb GUI) to interact with your databases. Here is the link: https://docs.mongodb.com/compass/master/install/
I hope this solves your problem.
I suggest you should use one of the mappers' libraries: Mapstruct, ModelMapper, etc. With Mapstruct your mapper will look like:
@Mapper
public interface UserMapper {
UserMapper INSTANCE = Mappers.getMapper( UserMapper.class );
UserDTO toDto(User user);
}
The real object with all getters and setters will be automatically generated from this interface. You can use it like:
UserDTO userDTO = UserMapper.INSTANCE.toDto(user);
You can also add some logic for your activeText filed using @AfterMapping annotation.
string path = HttpContext.Current.Server.MapPath("~/App_Data/somedata.xml");
string path = Server.MapPath("~/App_Data/somedata.xml");
@echo off
Set filename="C:\Documents and Settings\All Users\Desktop\Dostips.cmd"
call :expand %filename%
:expand
set filename=%~nx1
echo The name of the file is %filename%
set folder=%~dp1
echo It's path is %folder%
Alternatively to usleep()
, which is not defined in POSIX 2008 (though it was defined up to POSIX 2004, and it is evidently available on Linux and other platforms with a history of POSIX compliance), the POSIX 2008 standard defines nanosleep()
:
nanosleep
- high resolution sleep#include <time.h> int nanosleep(const struct timespec *rqtp, struct timespec *rmtp);
The
nanosleep()
function shall cause the current thread to be suspended from execution until either the time interval specified by therqtp
argument has elapsed or a signal is delivered to the calling thread, and its action is to invoke a signal-catching function or to terminate the process. The suspension time may be longer than requested because the argument value is rounded up to an integer multiple of the sleep resolution or because of the scheduling of other activity by the system. But, except for the case of being interrupted by a signal, the suspension time shall not be less than the time specified byrqtp
, as measured by the system clock CLOCK_REALTIME.The use of the
nanosleep()
function has no effect on the action or blockage of any signal.

Assuming you actually mean timestamp
because there is no datetime
in Postgres
Cast the timestamp column to a date, that will remove the time part:
select *
from the_table
where the_timestamp_column::date = date '2015-07-15';
This will return all rows from July, 15th.
Note that the above will not use an index on the_timestamp_column
. If performance is critical, you need to either create an index on that expression or use a range condition:
select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
and the_timestamp_column < timestamp '2015-07-16 00:00:00';
Based on the above post i tried this and this worked fine I wanted to use the value of Map B as keys for Map A:
<c:if test="${not empty activityCodeMap and not empty activityDescMap}">
<c:forEach var="valueMap" items="${auditMap}">
<tr>
<td class="activity_white"><c:out value="${activityCodeMap[valueMap.value.activityCode]}"/></td>
<td class="activity_white"><c:out value="${activityDescMap[valueMap.value.activityDescCode]}"/></td>
<td class="activity_white">${valueMap.value.dateTime}</td>
</tr>
</c:forEach>
</c:if>
It is better to use urlencode
here. Not much difference for single parameter but IMHO makes the code clearer. (It looks confusing to see a function quote_plus
! especially those coming from other languates)
In [21]: query='lskdfj/sdfkjdf/ksdfj skfj'
In [22]: val=34
In [23]: from urllib.parse import urlencode
In [24]: encoded = urlencode(dict(p=query,val=val))
In [25]: print(f"http://example.com?{encoded}")
http://example.com?p=lskdfj%2Fsdfkjdf%2Fksdfj+skfj&val=34
urlencode: https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urlencode
quote_plus: https://docs.python.org/3/library/urllib.parse.html#urllib.parse.quote_plus
got the below error

Below command solved the issue:
npm config set strict-ssl false
It is a bad idea to select * from anything, period. This is why SSMS adds every field name, even if there are hundreds, instead of select *. It is extremely inefficient regardless of how large the table is. If you don't know what the fields are, its still more efficient to pull them out of the INFORMATION_SCHEMA database than it is to select *.
A better query would be:
SELECT
COLUMN_NAME,
Case
When DATA_TYPE In ('varchar', 'char', 'nchar', 'nvarchar', 'binary')
Then convert(varchar(MAX), CHARACTER_MAXIMUM_LENGTH)
When DATA_TYPE In ('numeric', 'int', 'smallint', 'bigint', 'tinyint')
Then convert(varchar(MAX), NUMERIC_PRECISION)
When DATA_TYPE = 'bit'
Then convert(varchar(MAX), 1)
When DATA_TYPE IN ('decimal', 'float')
Then convert(varchar(MAX), Concat(Concat(NUMERIC_PRECISION, ', '), NUMERIC_SCALE))
When DATA_TYPE IN ('date', 'datetime', 'smalldatetime', 'time', 'timestamp')
Then ''
End As DATALEN,
DATA_TYPE

Uploading Files using Retrofit is Quite Simple You need to build your api interface as
public interface Api {
String BASE_URL = "http://192.168.43.124/ImageUploadApi/";
@Multipart
@POST("yourapipath")
Call<MyResponse> uploadImage(@Part("image\"; filename=\"myfile.jpg\" ") RequestBody file, @Part("desc") RequestBody desc);
}
in the above code image is the key name so if you are using php you will write $_FILES['image']['tmp_name'] to get this. And filename="myfile.jpg" is the name of your file that is being sent with the request.
Now to upload the file you need a method that will give you the absolute path from the Uri.
private String getRealPathFromURI(Uri contentUri) {
String[] proj = {MediaStore.Images.Media.DATA};
CursorLoader loader = new CursorLoader(this, contentUri, proj, null, null, null);
Cursor cursor = loader.loadInBackground();
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String result = cursor.getString(column_index);
cursor.close();
return result;
}
Now you can use the below code to upload your file.
private void uploadFile(Uri fileUri, String desc) {
//creating a file
File file = new File(getRealPathFromURI(fileUri));
//creating request body for file
RequestBody requestFile = RequestBody.create(MediaType.parse(getContentResolver().getType(fileUri)), file);
RequestBody descBody = RequestBody.create(MediaType.parse("text/plain"), desc);
//The gson builder
Gson gson = new GsonBuilder()
.setLenient()
.create();
//creating retrofit object
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Api.BASE_URL)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
//creating our api
Api api = retrofit.create(Api.class);
//creating a call and calling the upload image method
Call<MyResponse> call = api.uploadImage(requestFile, descBody);
//finally performing the call
call.enqueue(new Callback<MyResponse>() {
@Override
public void onResponse(Call<MyResponse> call, Response<MyResponse> response) {
if (!response.body().error) {
Toast.makeText(getApplicationContext(), "File Uploaded Successfully...", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), "Some error occurred...", Toast.LENGTH_LONG).show();
}
}
@Override
public void onFailure(Call<MyResponse> call, Throwable t) {
Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_LONG).show();
}
});
}

Here are my 2 cents on different options for completing this:
Third party tools: Probably the easiest way to get the job done is to create an empty database on lower version and then use third party tools to read the backup and synchronize new newly created database with the backup.
Red gate is one of the most popular but there are many others like ApexSQL Diff , ApexSQL Data Diff, Adept SQL, Idera …. All of these are premium tools but you can get the job done in trial mode ;)
Generating scripts: as others already mentioned you can always script structure and data using SSMS but you need to take into consideration the order of execution. By default object scripts are not ordered correctly and you’ll have to take care of the dependencies. This may be an issue if database is big and has a lot of objects.
Import and export wizard: This is not an ideal solution as it will not restore all objects but only data tables but you can consider it for quick and dirty fixes when it’s needed.
On the contrary, I do think working with list
makes it easy to automate such things.
Here is one solution (I stored your four dataframes in folder temp/
).
filenames <- list.files("temp", pattern="*.csv", full.names=TRUE)
ldf <- lapply(filenames, read.csv)
res <- lapply(ldf, summary)
names(res) <- substr(filenames, 6, 30)
It is important to store the full path for your files (as I did with full.names
), otherwise you have to paste the working directory, e.g.
filenames <- list.files("temp", pattern="*.csv")
paste("temp", filenames, sep="/")
will work too. Note that I used substr
to extract file names while discarding full path.
You can access your summary tables as follows:
> res$`df4.csv`
A B
Min. :0.00 Min. : 1.00
1st Qu.:1.25 1st Qu.: 2.25
Median :3.00 Median : 6.00
Mean :3.50 Mean : 7.00
3rd Qu.:5.50 3rd Qu.:10.50
Max. :8.00 Max. :16.00
If you really want to get individual summary tables, you can extract them afterwards. E.g.,
for (i in 1:length(res))
assign(paste(paste("df", i, sep=""), "summary", sep="."), res[[i]])
Simple, make a simple asp page with the designer (just for the beginning) Lets say the body is something like this:
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<br />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</div>
<p>
<asp:Button ID="Button1" runat="server" Text="Button" />
</p>
</form>
</body>
Great, now every asp object IS an object. So you can access it in the asp's CS code. The asp's CS code is triggered by events (mostly). The class will probably inherit from System.Web.UI.Page
If you go to the cs file of the asp page, you'll see a protected void Page_Load(object sender, EventArgs e) ... That's the load event, you can use that to populate data into your objects when the page loads.
Now, go to the button in your designer (Button1) and look at its properties, you can design it, or add events from there. Just change to the events view, and create a method for the event.
The button is a web control Button Add a Click event to the button call it Button1Click:
void Button1Click(Object sender,EventArgs e) { }
Now when you click the button, this method will be called. Because ASP is object oriented, you can think of the page as the actual class, and the objects will hold the actual current data.
So if for example you want to access the text in TextBox1
you just need to call that object in the C# code:
String firstBox = TextBox1.Text;
In the same way you can populate the objects when event occur.
Now that you have the data the user posted in the textboxes , you can use regular C# SQL connections to add the data to your database.
If you want to convert to integers only, another fast (and short) way is the double-bitwise not (i.e. using two tilde characters):
e.g.
~~x;
Reference: http://james.padolsey.com/cool-stuff/double-bitwise-not/
The 5 common ways I know so far to convert a string to a number all have their differences (there are more bitwise operators that work, but they all give the same result as ~~
). This JSFiddle shows the different results you can expect in the debug console: http://jsfiddle.net/TrueBlueAussie/j7x0q0e3/22/
var values = ["123",
undefined,
"not a number",
"123.45",
"1234 error",
"2147483648",
"4999999999"
];
for (var i = 0; i < values.length; i++){
var x = values[i];
console.log(x);
console.log(" Number(x) = " + Number(x));
console.log(" parseInt(x, 10) = " + parseInt(x, 10));
console.log(" parseFloat(x) = " + parseFloat(x));
console.log(" +x = " + +x);
console.log(" ~~x = " + ~~x);

Number(x) = NaN
parseInt(x, 10) = 1234
parseFloat(x) = 1234
+x = NaN
~~x = 0
2147483648
Number(x) = 2147483648
parseInt(x, 10) = 2147483648
parseFloat(x) = 2147483648
+x = 2147483648
~~x = -2147483648
4999999999
Number(x) = 4999999999
parseInt(x, 10) = 4999999999
parseFloat(x) = 4999999999
+x = 4999999999
~~x = 705032703
The ~~x
version results in a number in "more" cases, where others often result in undefined
, but it fails for invalid input (e.g. it will return 0
if the string contains non-number characters after a valid number).
Please note: Integer overflow and/or bit truncation can occur with ~~
, but not the other conversions. While it is unusual to be entering such large values, you need to be aware of this. Example updated to include much larger values.
Some Perf tests indicate that the standard parseInt
and parseFloat
functions are actually the fastest options, presumably highly optimised by browsers, but it all depends on your requirement as all options are fast enough: http://jsperf.com/best-of-string-to-number-conversion/37
This all depends on how the perf tests are configured as some show parseInt/parseFloat to be much slower.
Not pretty good solution, but you can try the hjson tool. It allows you to write text multi-lined in editor and then converts it to the proper valid JSON format.
Note: it adds '\n' characters for the new lines, but you can simply delete them in any text editor with the "Replace all.." function.
I haven't done web design for iOS but from what I recall seeing in the WWDC sessions and in documentation, the search bar in Mobile Safari, and navigation bars across the OS, will now automatically resize and shrink to show more of your content.
You can test this in Safari on an iPhone and notice that, when you scroll down to see more contents on a page, the navigation/search bar is hidden automatically.
Perhaps leaving the address bar/navigation bar as is, and not creating a full-screen experience, is what's best. I don't see Apple doing that anytime soon. And at most they are not automatically controlling when the address bar shows/hides.
Sure, you are losing screen real estate, specially on an iPhone 4 or 4S, but there doesn't seem to be an alternative as of Beta 4.
Mark, this is already answered in your previous topic. But OK, here it is again:
Suppose ${list}
points to a List<Object>
, then the following
<c:forEach items="${list}" var="item">
${item}<br>
</c:forEach>
does basically the same as as following in "normal Java":
for (Object item : list) {
System.out.println(item);
}
If you have a List<Map<K, V>>
instead, then the following
<c:forEach items="${list}" var="map">
<c:forEach items="${map}" var="entry">
${entry.key}<br>
${entry.value}<br>
</c:forEach>
</c:forEach>
does basically the same as as following in "normal Java":
for (Map<K, V> map : list) {
for (Entry<K, V> entry : map.entrySet()) {
System.out.println(entry.getKey());
System.out.println(entry.getValue());
}
}
The key
and value
are here not special methods or so. They are actually getter methods of Map.Entry
object (click at the blue Map.Entry
link to see the API doc). In EL (Expression Language) you can use the .
dot operator to access getter methods using "property name" (the getter method name without the get
prefix), all just according the Javabean specification.
That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".
You could achieve this with a simple for
loop:
var min = 12,
max = 100,
select = document.getElementById('selectElementId');
for (var i = min; i<=max; i++){
var opt = document.createElement('option');
opt.value = i;
opt.innerHTML = i;
select.appendChild(opt);
}
JS Perf comparison of both mine and Sime Vidas' answer, run because I thought his looked a little more understandable/intuitive than mine and I wondered how that would translate into implementation. According to Chromium 14/Ubuntu 11.04 mine is somewhat faster, other browsers/platforms are likely to have differing results though.
Edited in response to comment from OP:
[How] do [I] apply this to more than one element?
function populateSelect(target, min, max){
if (!target){
return false;
}
else {
var min = min || 0,
max = max || min + 100;
select = document.getElementById(target);
for (var i = min; i<=max; i++){
var opt = document.createElement('option');
opt.value = i;
opt.innerHTML = i;
select.appendChild(opt);
}
}
}
// calling the function with all three values:
populateSelect('selectElementId',12,100);
// calling the function with only the 'id' ('min' and 'max' are set to defaults):
populateSelect('anotherSelect');
// calling the function with the 'id' and the 'min' (the 'max' is set to default):
populateSelect('moreSelects', 50);
And, finally (after quite a delay...), an approach extending the prototype of the HTMLSelectElement
in order to chain the populate()
function, as a method, to the DOM node:
HTMLSelectElement.prototype.populate = function (opts) {
var settings = {};
settings.min = 0;
settings.max = settings.min + 100;
for (var userOpt in opts) {
if (opts.hasOwnProperty(userOpt)) {
settings[userOpt] = opts[userOpt];
}
}
for (var i = settings.min; i <= settings.max; i++) {
this.appendChild(new Option(i, i));
}
};
document.getElementById('selectElementId').populate({
'min': 12,
'max': 40
});

You can do something like that
<div style="background-image: url(http://your-image.jpg); position:relative;">
<img src="http://your-image.jpg" style="opacity: 0;" />
<div style="position: absolute;top: 0;width: 100%;height: 100%;">my content goes here</div>
</div>
Existing code is working, but is blocking the thread.
.Select(async ev => await ProcessEventAsync(ev))
creates a new Task for every event, but
.Select(t => t.Result)
blocks the thread waiting for each new task to end.
In the other hand your code produce the same result but keeps asynchronous.
Just one comment on your first code. This line
var tasks = await Task.WhenAll(events...
will produce a single Task<TResult[]> so the variable should be named in singular.
Finally your last code make the same but is more succinct.
For reference: Task.Wait / Task.WhenAll
First of all, like Steven Rumbalski said, "PEP8 doesn't address this question", so it is a matter of personal preference.
I would use a similar but not identical format as your format 3. Here is mine, and why.
my_dictionary = { # Don't think dict(...) notation has more readability
"key1": 1, # Indent by one press of TAB (i.e. 4 spaces)
"key2": 2, # Same indentation scale as above
"key3": 3, # Keep this final comma, so that future addition won't show up as 2-lines change in code diff
} # My favorite: SAME indentation AS ABOVE, to emphasize this bracket is still part of the above code block!
the_next_line_of_code() # Otherwise the previous line would look like the begin of this part of code
bad_example = {
"foo": "bar", # Don't do this. Unnecessary indentation wastes screen space
"hello": "world" # Don't do this. Omitting the comma is not good.
} # You see? This line visually "joins" the next line when in a glance
the_next_line_of_code()
btw_this_is_a_function_with_long_name_or_with_lots_of_parameters(
foo='hello world', # So I put one parameter per line
bar=123, # And yeah, this extra comma here is harmless too;
# I bet not many people knew/tried this.
# Oh did I just show you how to write
# multiple-line inline comment here?
# Basically, same indentation forms a natural paragraph.
) # Indentation here. Same idea as the long dict case.
the_next_line_of_code()
# By the way, now you see how I prefer inline comment to document the very line.
# I think this inline style is more compact.
# Otherwise you will need extra blank line to split the comment and its code from others.
some_normal_code()
# hi this function is blah blah

Late to the party, but this might be of interest for people looking to add custom fonts to their ggplots
inside a shiny
app on shinyapps.io.
You can:
This leads to the following upper section inside the app.R
file:
dir.create('~/.fonts')
file.copy("www/IndieFlower.ttf", "~/.fonts")
system('fc-cache -f ~/.fonts')
A full example app can be found here.
Add path of your PHP to Windows System Path. The path should contain php.exe
.
After adding the path open a new command prompt and make sure php.exe
is in path by typing
C:\>php --help
Once you see proper help message from above, enable the php_ldap.dll
extension in php.ini
Also copy php_ldap.dll
from php/ext
directory to apache/bin
folder
Restart wamp and phpinfo()
will now show ldap enabled.
If the values are not unique, the safe way to inverse the map is by using java 8's groupingBy function
Map<String, Integer> map = new HashMap<>();
map.put("a",1);
map.put("b",2);
Map<Integer, List<String>> mapInversed =
map.entrySet()
.stream()
.collect(Collectors.groupingBy(Map.Entry::getValue, Collectors.mapping(Map.Entry::getKey, Collectors.toList())))

That's correct, and documented:
http://java.sun.com/javase/6/docs/api/java/util/Collections.html#synchronizedList(java.util.List)
However, to clear the list, just call List.clear().
you can:
use integer;
it is explained by Michael Ratanapintha or else use manually:
$a=3.7;
$b=2.1;
$c=int(int($a)/int($b));
notice, 'int' is not casting. this is function for converting number to integer form. this is because Perl 5 does not have separate integer division. exception is when you 'use integer'. Then you will lose real division.
The only way I've managed to do this is by using overflow: visible;
and width: 20000px;
on the parent element. There is no way to do this with CSS level 1 that I'm aware of and I refused to think I'd have to go all gung-ho with CSS level 3. The example below has 18 menus that extend beyond my 1920x1200 resolution LCD, if your screen is larger just duplicate the first tier menu elements or just resize the browser. Alternatively and with slightly lower levels of browser compatibility you could use CSS3 media queries.

If you are a Vim aficionado...
You can recursively os.path.split
the string
import os
def parts(path):
p,f = os.path.split(path)
return parts(p) + [f] if f else [p]
Testing this against some path strings, and reassembling the path with os.path.join
>>> for path in [
... r'd:\stuff\morestuff\furtherdown\THEFILE.txt',
... '/path/to/file.txt',
... 'relative/path/to/file.txt',
... r'C:\path\to\file.txt',
... r'\\host\share\path\to\file.txt',
... ]:
... print parts(path), os.path.join(*parts(path))
...
['d:\\', 'stuff', 'morestuff', 'furtherdown', 'THEFILE.txt'] d:\stuff\morestuff\furtherdown\THEFILE.txt
['/', 'path', 'to', 'file.txt'] /path\to\file.txt
['', 'relative', 'path', 'to', 'file.txt'] relative\path\to\file.txt
['C:\\', 'path', 'to', 'file.txt'] C:\path\to\file.txt
['\\\\', 'host', 'share', 'path', 'to', 'file.txt'] \\host\share\path\to\file.txt
The first element of the list may need to be treated differently depending on how you want to deal with drive letters, UNC paths and absolute and relative paths. Changing the last [p]
to [os.path.splitdrive(p)]
forces the issue by splitting the drive letter and directory root out into a tuple.
import os
def parts(path):
p,f = os.path.split(path)
return parts(p) + [f] if f else [os.path.splitdrive(p)]
[('d:', '\\'), 'stuff', 'morestuff', 'furtherdown', 'THEFILE.txt']
[('', '/'), 'path', 'to', 'file.txt']
[('', ''), 'relative', 'path', 'to', 'file.txt']
[('C:', '\\'), 'path', 'to', 'file.txt']
[('', '\\\\'), 'host', 'share', 'path', 'to', 'file.txt']
Edit: I have realised that this answer is very similar to that given above by user1556435. I'm leaving my answer up as the handling of the drive component of the path is different.

To send HTML contents in the body of the mail on the go with Sender and Recipient mail address in single line, you may try the below,
export EMAIL="[email protected]" && mutt -e "my_hdr Content-Type: text/html" -s "Test Mail" "[email protected]" < body_html.html
File: body_html.html
<HTML>
<HEAD> Test Mail </HEAD>
<BODY>
<p>This is a <strong><span style="color: #ff0000;">test mail!</span></strong></p>
</BODY>
</HTML>
Note: Tested in RHEL, CentOS, Ubuntu.
Use the class URLEncoder:
URLEncoder.encode(String s, String enc)
Where :
s - String to be translated.
enc - The name of a supported character encoding.
Standard charsets:
US-ASCII Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set ISO-8859-1 ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1
UTF-8 Eight-bit UCS Transformation Format
UTF-16BE Sixteen-bit UCS Transformation Format, big-endian byte order
UTF-16LE Sixteen-bit UCS Transformation Format, little-endian byte order
UTF-16 Sixteen-bit UCS Transformation Format, byte order identified by an optional byte-order mark
Example:
import java.net.URLEncoder;
String stringEncoded = URLEncoder.encode(
"This text must be encoded! aeiou áéíóú ñ, peace!", "UTF-8");
set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%
The single quotes do not indicate a string, they make it starts: 'C:\
instead of C:\
so
%name%
is the usual syntax for expanding a variable, the !name!
syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION
first, or by running the command prompt with CMD /V:ON
.
Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4
to keep the current PATH content, and add something to the end.
Also worth mentioning are
I have used HPCToolkit and VTune and they are very effective at finding the long pole in the tent and do not need your code to be recompiled (except that you have to use -g -O or RelWithDebInfo type build in CMake to get meaningful output). I have heard TAU is similar in capabilities.
Lets suppose you have N elements in a heap. Then its height would be Log(N)
Now you want to insert another element, then the complexity would be : Log(N), we have to compare all the way UP to the root.
Now you are having N+1 elements & height = Log(N+1)
Using induction technique it can be proved that the complexity of insertion would be ?logi.
Now using
log a + log b = log ab
This simplifies to : ?logi=log(n!)
which is actually O(NlogN)
But
we are doing something wrong here, as in all the case we do not reach at the top. Hence while executing most of the times we may find that, we are not going even half way up the tree. Whence, this bound can be optimized to have another tighter bound by using mathematics given in answers above.
This realization came to me after a detail though & experimentation on Heaps.
You can create config once and use it everywhere.
const instance = axios.create({
baseURL: 'https://some-domain.com/api/',
timeout: 1000,
headers: {'Authorization': 'Bearer '+token}
});
instance.get('/path')
.then(response => {
return response.data;
})
Change var data = 'id='+ id & 'name='+ name;
as below,
use this instead.....
var data = "id="+ id + "&name=" + name;
this will going to work fine:)
You can use the LocalCommand
command-line option if the PermitLocalCommand
option is enabled:
ssh username@hostname -o LocalCommand="tmux list-sessions"
For more details about the available options, see the ssh_config
man page.
For new Qt users this is a little more confusing than it seems if you are using QT Designer and .ui
files.
Initially I tried to use ui->setWindowTitle
, but that doesn't exist. ui
is not a QDialog
or a QMainWindow
.
The owner of the ui
is the QDialog
or QMainWindow
, the .ui
just describes how to lay it out. In that case, you would use:
this->setWindowTitle("New Title");
I hope this helps someone else.
You cannot load images directly with @2x
or @3x
, system selects appropriate image automatically, just specify the name using UIImage
:
UIImage(named: "green-square-Retina")
I had a different cause for this error. I tried to insert a date without using quotes and received a strange error telling me I had tried to insert a date from 2003.
Although I was already using the YYYY-MM-DD format, I forgot to add quotes around the date. Even though it is a date and not a string, quotes are still required.
I use Strongloop's cli tools for that; see https://strongloop.com/strongblog/switch-between-configure-public-and-private-npm-registry/ for more information
Switching between repositories is as easy as : slc registry use <name>
You can also do that by :sus
to fall into shell and back by fg
.
The code below would be a bit more efficient than the answers presented above when dealing with larger datasets.
SELECT * FROM Call WHERE
NOT EXISTS (SELECT 'x' FROM Phone_book where
Phone_book.phone_number = Call.phone_number)
This deletes only files from ABC (sub-directories are untouched):
Arrays.stream(new File("C:/test/ABC/").listFiles()).forEach(File::delete);
This deletes only files from ABC (and sub-directories):
Files.walk(Paths.get("C:/test/ABC/"))
.filter(Files::isRegularFile)
.map(Path::toFile)
.forEach(File::delete);
^ This version requires handling the IOException
This is a massively late reply, but I think useful for future reference. Rather than write your own math parser (although the pyparsing example above is great) you could use SymPy. I don't have a lot of experience with it, but it contains a much more powerful math engine than anyone is likely to write for a specific application and the basic expression evaluation is very easy:
>>> import sympy
>>> x, y, z = sympy.symbols('x y z')
>>> sympy.sympify("x**3 + sin(y)").evalf(subs={x:1, y:-3})
0.858879991940133
Very cool indeed! A from sympy import *
brings in a lot more function support, such as trig functions, special functions, etc., but I've avoided that here to show what's coming from where.

We need to put some kind of control that can wrap text like textblock/textbox

<TextBlock TextWrapping="Wrap">
this is a very long text inside a textblock and this needs to be on multiline.
</TextBlock>
</Label>
Use "%~1"
. %~1
alone removes surrounding quotes. However since you can't know whether the input parameter %1
has quotes or not, you should ensure by "%~1"
that they are added for sure. This is especially helpful when concatenating variables, e.g. convert.exe "%~1.input" "%~1.output"
Apparently (having faced related 64- and 32-bit issues on OS X) there is a bug in the Windows installer. I stumbled across this workaround, which might help - basically, you create your own registry value HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\2.6\InstallPath
and copy over the InstallPath value from HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\InstallPath
. See the answer below for more details.
If you do this, beware that setuptools may only install 32-bit libraries.
NOTE: the responses below offer more detail, so please read them too.
Many JavaScript libraries (especially non-recent ones) do not handle IE9 well because it breaks with IE8 in the handling of a lot of things.
JS code that sniffs for IE will fail quite frequently in IE9, unless such code is rewritten to handle IE9 specifically.
Before the JS code is updated, you should use the "X-UA-Compatible" meta tag to force your web page into IE8 mode.
EDIT: Can't believe that, 3 years later and we're onto IE11, and there are still up-votes for this. :-) Many JS libraries should now at least support IE9 natively and most support IE10, so it is unlikely that you'll need the meta tag these days, unless you don't intend to upgrade your JS library. But beware that IE10 changes things regarding to cross-domain scripting and some CDN-based library code breaks. Check your library version. For example, Dojo 1.9 on the CDN will break on IE10, but 1.9.1 solves it.
EDIT 2: You REALLY need to get your acts together now. We are now in mid-2014!!! I am STILL getting up-votes for this! Revise your sites to get rid of old-IE hard-coded dependencies!
Sigh... If I had known that this would be by far my most popular answer, I'd probably have spent more time polishing it...
EDIT 3: It is now almost 2016. Upvotes still ticking up... I guess there are lots of legacy code out there... One day our programs will out-live us...
Use the os.path
module.
os.path.join( "C:", "meshes", "as" )
Or use raw strings
r"C:\meshes\as"
I would also recommend no spaces in the path or file names. And you could use double backslashes in your strings.
"C:\\meshes\\as.jpg"
The default port 1433 is used when there is only one SQL Server named instance running on the computer.
When multiple SQL Server named instances are running, they run by default under a dynamic port (49152–65535). In this scenario, an application will connect to the SQL Server Browser service port (UDP 1434) to get the dynamic port and then connect to the dynamic port directly.
