LocalDateTime does not contain Zone information. ZonedDatetime does.
If you want to convert LocalDateTime to UTC, you need to wrap by ZonedDateTime fist.
You can convert like the below.
LocalDateTime ldt = LocalDateTime.now();
System.out.println(ldt.toLocalTime());
ZonedDateTime ldtZoned = ldt.atZone(ZoneId.systemDefault());
ZonedDateTime utcZoned = ldtZoned.withZoneSameInstant(ZoneId.of("UTC"));
System.out.println(utcZoned.toLocalTime());
Assuming thant the content of mandrill_events
is an object (not a string), you can also use shift()
function:
var req = { mandrill_events: [{"event":"inbound","ts":1426249238}] };
var event-property = req.mandrill_events.shift().event;
curl is an extension that needs to be installed, it's got nothing to do with the PHP version.

Yes - according to the pandas.read_csv
documentation:
Note: A fast-path exists for iso8601-formatted dates.
So if your csv has a column named datetime
and the dates looks like 2013-01-01T01:01
for example, running this will make pandas (I'm on v0.19.2) pick up the date and time automatically:
df = pd.read_csv('test.csv', parse_dates=['datetime'])
Note that you need to explicitly pass parse_dates
, it doesn't work without.
Verify with:
df.dtypes
You should see the datatype of the column is datetime64[ns]

Misko already gave an excellent description of how the data bindings work, but I would like to add my view on the performance issue with the data binding.
As Misko stated, around 2000 bindings are where you start to see problems, but you shouldn't have more than 2000 pieces of information on a page anyway. This may be true, but not every data-binding is visible to the user. Once you start building any sort of widget or data grid with two-way binding you can easily hit 2000 bindings, without having a bad UX.
Consider, for example, a combo box where you can type text to filter the available options. This sort of control could have ~150 items and still be highly usable. If it has some extra feature (for example a specific class on the currently selected option) you start to get 3-5 bindings per option. Put three of these widgets on a page (e.g. one to select a country, the other to select a city in the said country, and the third to select a hotel) and you are somewhere between 1000 and 2000 bindings already.
Or consider a data-grid in a corporate web application. 50 rows per page is not unreasonable, each of which could have 10-20 columns. If you build this with ng-repeats, and/or have information in some cells which uses some bindings, you could be approaching 2000 bindings with this grid alone.
I find this to be a huge problem when working with AngularJS, and the only solution I've been able to find so far is to construct widgets without using two-way binding, instead of using ngOnce, deregistering watchers and similar tricks, or construct directives which build the DOM with jQuery and DOM manipulation. I feel this defeats the purpose of using Angular in the first place.
I would love to hear suggestions on other ways to handle this, but then maybe I should write my own question. I wanted to put this in a comment, but it turned out to be way too long for that...
TL;DR
The data binding can cause performance issues on complex pages.
Yes you can. You can even test it:
var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
console.log(++i);_x000D_
if (i === 5) clearInterval(timer);_x000D_
console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);
_x000D_
In this example, this timer clears when i
reaches 5.
All these answers are correct, but I had to also check if the string contains other characters and Hebrew letters so I simply used:
if (!str.match(/^[\d]+$/)) {
//contains other characters as well
}
There is also the new Android Scripting Environment (ASE/SL4A) project. It looks awesome, and it has some integration with native Android components.
Note: no longer under "active development", but some forks may be.
This is what you need in 1 line of code.
Route::get('/groups/{groupId}', 'GroupsController@getShow');
Suggestion: Use CamelCase as opposed to underscores, try & follow PSR-* guidelines.
Hope it helps.
It's old but thought I'd add my two cents... Not sure if it will work but try using a KeyValuePair:
List<KeyValuePair<?, ?>> LinkList = new List<KeyValuePair<?, ?>>();
LinkList.Add(new KeyValuePair<?, ?>(Object, Object));
You'll end up with something like this:
LinkList[0] = <Object, Object>
LinkList[1] = <Object, Object>
LinkList[2] = <Object, Object>
and so on...

Imagine you have have a Book model and a Page model,

One book can have **many** pages. One page can only be in **one** book.
N:N means:
One book can have **many** pages. And one page can be in **many** books.
strncpy is NOT safer than strcpy, it just trades one type of bugs with another. In C, when handling C strings, you need to know the size of your buffers, there is no way around it. strncpy was justified for the directory thing mentioned by others, but otherwise, you should never use it:
One way of doing it would be also with ACE OLEDB Provider (see also connection strings for Excel). Of course you'd have to have the provider installed and registered. You should have it, if you have Excel installed, but this is something you have to consider when deploying the app.
This is the example of calling the helper method from ExportHelper
: ExportHelper.CreateXlsFromDataTable(myDataTable, @"C:\tmp\export.xls");
The helper for exporting to Excel file using ACE OLEDB:
public class ExportHelper

cmd.ExecuteNonQuery();

AddNewRow(conn, dataExportRow);

As per my understanding data structure is any data residing in memory of any electronic system that can be efficiently managed. Many times it is a game of memory or faster accessibility of data. In terms of memory again, there are tradeoffs done with the management of data based on cost to the company of that end product. Efficiently managed tells us how best the data can be accessed based on the primary requirement of the end product. This is a very high level explanation but data structures is a vast subjects. Most of the interviewers dive into data structures that they can afford to discuss in the interviews depending on the time they have, which are linked lists and related subjects.
Now, these data types can be divided into primitive, abstract, composite, based on the way they are logically constructed and accessed.
I hope this helps you dive in.
jQuery.parseJSON is useful for success and error.
$.ajax({
url: "controller/action",
type: 'POST',
success: function (data, textStatus, jqXHR) {
var obj = jQuery.parseJSON(jqXHR.responseText);
notify(data.toString());
notify(textStatus.toString());
},
error: function (data, textStatus, jqXHR) { notify(textStatus); }
});
Not as a command, but this information is in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment
CurrentVersion
REG_SZJava Runtime Environment
named with the CurrentVersion
valueJavaHome
REG_SZ to get the pathFor example on my workstation i have
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment
CurrentVersion = "1.6"
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.5
JavaHome = "C:\Program Files\Java\jre1.5.0_20"
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.6
JavaHome = "C:\Program Files\Java\jre6"
So my current JRE is in C:\Program Files\Java\jre6
If can deviate a little from the straight path of DataTable -> SQL table, it can also be done via a list of objects:
1) DataTable -> Generic list of objects
public static DataTable ConvertTo<T>(IList<T> list)
{
DataTable table = CreateTable<T>();
Type entityType = typeof(T);
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(entityType);
foreach (T item in list)
{
DataRow row = table.NewRow();
foreach (PropertyDescriptor prop in properties)
{
row[prop.Name] = prop.GetValue(item);
}
table.Rows.Add(row);
}
return table;
}
Source and more details can be found here. Missing properties will remain to their default values (0 for int
s, null for reference types etc.)
2) Push the objects into the database
One way is to use EntityFramework.BulkInsert
extension. An EF datacontext is required, though.
It generates the BULK INSERT command required for fast insert (user defined table type solution is much slower than this).
Although not the straight method, it helps constructing a base of working with list of objects instead of DataTable
s which seems to be much more memory efficient.
You can use this code
var stringDate = "2005-07-08T00:00:00+0000";
var dTimezone = new Date();
var offset = dTimezone.getTimezoneOffset() / 60;
var date = new Date(Date.parse(stringDate));
date.setHours(date.getHours() + offset);
If you are using Windows, then the WPN-XM Server Stack might be a suitable alternative.
I had a similar issue, trying to run a WCF-based HttpSelfHostServer in Debug under my VisualStudio 2013. I tried every possible direction (turn off firewall, disabling IIS completely to eliminate the possibility localhost port is taken by some other service, etc.).
Eventually, what "did the trick" (solved the problem) was re-running VisualStudio 2013 as Administrator.
Amazing.
IPython has profiles for configuration, located at ~/.ipython/profile_*
. The default profile is called profile_default
. Within this folder there are two primary configuration files:
ipython_config.py
ipython_kernel_config.py
Add the inline option for matplotlib to ipython_kernel_config.py
:
c = get_config()
# ... Any other configurables you want to set
c.InteractiveShellApp.matplotlib = "inline"
Usage of %pylab
to get inline plotting is discouraged.
It introduces all sorts of gunk into your namespace that you just don't need.
%matplotlib
on the other hand enables inline plotting without injecting your namespace. You'll need to do explicit calls to get matplotlib and numpy imported.
import matplotlib.pyplot as plt
import numpy as np
The small price of typing out your imports explicitly should be completely overcome by the fact that you now have reproducible code.
You can do it by a combination of javascript and php:
<div id="cont"></div>
And by the other side;
<script>
var h = window.location.hash;
var h1 = (win.substr(1));//string with no #
var q1 = '<input type="text" id="hash" name="hash" value="'+h1+'">';
setInterval(function(){
if(win1!="")
{
document.querySelector('#cont').innerHTML = q1;
} else alert("Something went wrong")
},1000);
</script>
Then, on form submit you can retrieve the value via $_POST['hash'] (set the form)
You can apply your style to all the div and re-initialize the last one with :last-child:
for example in CSS:
.yourclass{
border: 1px solid blue;
}
.yourclass:last-child{
border: 0;
}
or in SCSS:
.yourclass{
border: 1px solid rgba(255, 255, 255, 1);
&:last-child{
border: 0;
}
}
To check are the following:
ssh -vvv [email protected]
to see debug logs. If thing goes well, github.com will be added to known_hosts.chmod 700 id_rsa
)After all checks, try ssh -vvv [email protected]
.
You can use exit method to quit an ios app :
exit(0);
You should say same alert message and ask him to quit
Another way is by using [[NSThread mainThread] exit]
However you should not do this way
According to Apple, your app should not terminate on its own. Since the user did not hit the Home button, any return to the Home screen gives the user the impression that your app crashed. This is confusing, non-standard behavior and should be avoided.

Have a look at http://sqlite.org/lang_conflict.html.
You want something like:
insert or replace into Book (ID, Name, TypeID, Level, Seen) values
((select ID from Book where Name = "SearchName"), "SearchName", ...);
Note that any field not in the insert list will be set to NULL if the row already exists in the table. This is why there's a subselect for the ID
column: In the replacement case the statement would set it to NULL and then a fresh ID would be allocated.
This approach can also be used if you want to leave particular field values alone if the row in the replacement case but set the field to NULL in the insert case.
For example, assuming you want to leave Seen
alone:
insert or replace into Book (ID, Name, TypeID, Level, Seen) values (
(select ID from Book where Name = "SearchName"),
"SearchName",
5,
6,
(select Seen from Book where Name = "SearchName"));
Basically this is what you need to do:
in the first activity:
Intent intent = new Intent();
intent.setAction(this, SecondActivity.class);
intent.putExtra(tag, value);
startActivity(intent);
and in the second activtiy:
Intent intent = getIntent();
intent.getBooleanExtra(tag, defaultValue);
intent.getStringExtra(tag, defaultValue);
intent.getIntegerExtra(tag, defaultValue);
one of the get-functions will give return you the value, depending on the datatype you are passing through.
The above options works for Google big query file also. I exported a table data to goodle cloud storage and downloaded from there. While loading the same to sql server was facing this issue and could successfully load the file after specifying the row delimiter as
ROWTERMINATOR = '0x0a'
Pay attention to header record as well and specify
FIRSTROW = 2
My final block for data file export from google bigquery looks like this.
BULK INSERT TABLENAME
FROM 'C:\ETL\Data\BigQuery\In\FILENAME.csv'
WITH
(
FIRSTROW = 2,
FIELDTERMINATOR = ',', --CSV field delimiter
ROWTERMINATOR = '0x0a',--Files are generated with this row terminator in Google Bigquery
TABLOCK
)
I like Felipe Leusin's approach best - make sure browsers get JSON without compromising content negotiation from clients that actually want XML. The only missing piece for me was that the response headers still contained content-type: text/html. Why was that a problem? Because I use the JSON Formatter Chrome extension, which inspects content-type, and I don't get the pretty formatting I'm used to. I fixed that with a simple custom formatter that accepts text/html requests and returns application/json responses:
public class BrowserJsonFormatter : JsonMediaTypeFormatter
{
public BrowserJsonFormatter() {
this.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
this.SerializerSettings.Formatting = Formatting.Indented;
}
public override void SetDefaultContentHeaders(Type type, HttpContentHeaders headers, MediaTypeHeaderValue mediaType) {
base.SetDefaultContentHeaders(type, headers, mediaType);
headers.ContentType = new MediaTypeHeaderValue("application/json");
}
}
Register like so:
config.Formatters.Add(new BrowserJsonFormatter());
Beamer just delegates responsibility for managing layout of itemize
environments back to the base LaTeX packages, so there's nothing funky you need to do in Beamer itself to alter the apperaance / layout of your lists.
Since Beamer redefines itemize, item, etc., the fully proper way to manipulate things like indentation is to redefine the Beamer templates. I get the impression that you're not looking to go that far, but if that's not the case, let me know and I'll elaborate.
There are at least three ways of accomplishing your goal from within your document, without mussing about with Beamer templates.
itemize
In the following code snippet, you can change the value of \itemindent
from 0em
to whatever you please, including negative values. 0em
is the default item indentation.
The advantage of this method is that the list is styled normally. The disadvantage is that Beamer's redefinition of itemize
and \item
means that the number of paramters that can be manipulated to change the list layout is limited. It can be very hard to get the spacing right with multi-line items.
\begin{itemize}
\setlength{\itemindent}{0em}
\item This is a normally-indented item.
\end{itemize}
list
In the following code snippet, the second parameter to \list
is the bullet to use, and the third parameter is a list of layout parameters to change. The \leftmargin
parameter adjusts the indentation of the entire list item and all of its rows; \itemindent
alters the indentation of subsequent lines.
The advantage of this method is that you have all of the flexibility of lists in non-Beamer LaTeX. The disadvantage is that you have to setup the bullet style (and other visual elements) manually (or identify the right command for the template you're using). Note that if you leave the second argument empty, no bullet will be displayed and you'll save some horizontal space.
\begin{list}{$\square$}{\leftmargin=1em \itemindent=0em}
\item This item uses the margin and indentation provided above.
\end{list}
customlist
environmentThe shortcomings of the list
solution can be ameliorated by defining a new customlist
environment that basically redefines the itemize
environment from Beamer but also incorporates the \leftmargin
and \itemindent
(etc.) parameters. Put the following in your preamble:
\makeatletter
\newenvironment{customlist}[2]{
\ifnum\@itemdepth >2\relax\@toodeep\else
\advance\@itemdepth\@ne%
\beamer@computepref\@itemdepth%
\usebeamerfont{itemize/enumerate \beameritemnestingprefix body}%
\usebeamercolor[fg]{itemize/enumerate \beameritemnestingprefix body}%
\usebeamertemplate{itemize/enumerate \beameritemnestingprefix body begin}%
\begin{list}
{
\usebeamertemplate{itemize \beameritemnestingprefix item}
}
{ \leftmargin=#1 \itemindent=#2
\def\makelabel##1{%
{%
\hss\llap{{%
\usebeamerfont*{itemize \beameritemnestingprefix item}%
\usebeamercolor[fg]{itemize \beameritemnestingprefix item}##1}}%
}%
}%
}
\fi
}
{
\end{list}
\usebeamertemplate{itemize/enumerate \beameritemnestingprefix body end}%
}
\makeatother
Now, to use an itemized list with custom indentation, you can use the following environment. The first argument is for \leftmargin
and the second is for \itemindent
. The default values are 2.5em and 0em respectively.
\begin{customlist}{2.5em}{0em}
\item Any normal item can go here.
\end{customlist}
A custom bullet style can be incorporated into the customlist
solution using the standard Beamer mechanism of \setbeamertemplate
. (See the answers to this question on the TeX Stack Exchange for more information.)
Alternatively, the bullet style can just be modified directly within the environment, by replacing \usebeamertemplate{itemize \beameritemnestingprefix item}
with whatever bullet style you'd like to use (e.g. $\square$
).
A cleaner Python3 version that use standard numpy, matplotlib and PIL. Merging the answer for opening from URL.
import matplotlib.pyplot as plt
from PIL import Image
import numpy as np
pil_im = Image.open('image.png') #Take jpg + png
## Uncomment to open from URL
#import requests
#r = requests.get('https://www.vegvesen.no/public/webkamera/kamera?id=131206')
#pil_im = Image.open(BytesIO(r.content))
im_array = np.asarray(pil_im)
plt.imshow(im_array)
plt.show()
You can use wget which is popular downloading shell tool for that. https://pypi.python.org/pypi/wget This will be the simplest method since it does not need to open up the destination file. Here is an example.
import wget
url = 'https://i1.wp.com/python3.codes/wp-content/uploads/2015/06/Python3-powered.png?fit=650%2C350'
wget.download(url, '/Users/scott/Downloads/cat4.jpg')
Python 2:
with open("datafile") as myfile:
head = [next(myfile) for x in xrange(N)]
print head
Python 3:
with open("datafile") as myfile:
head = [next(myfile) for x in range(N)]
print(head)
Here's another way (both Python 2 & 3):
from itertools import islice
with open("datafile") as myfile:
head = list(islice(myfile, N))
print(head)
In Web API (by default) methods are chosen based on a combination of HTTP method and route values.
MyVm
looks like a complex object, read by formatter from the body so you have two identical methods in terms of route data (since neither of them has any parameters from the route) - which makes it impossible for the dispatcher (IHttpActionSelector
) to match the appropriate one.
You need to differ them by either querystring or route parameter to resolve ambiguity.
Try creating a javascript function which runs this:
document.getElementById("youriframeid").contentWindow.location.reload(true);
Or maybe use an HTML workaround:
<html>
<body>
<center>
<a href="pagename.htm" target="middle">Refresh iframe</a>
<p>
<iframe src="pagename.htm" name="middle">
</p>
</center>
</body>
</html>
Both might be what you're looking for...

You have compiled your code with references to the correct math.h header file, but when you attempted to link it, you forgot the option to include the math library. As a result, you can compile your .o object files, but not build your executable.
As Paul has already mentioned add "-lm
" to link with the math library in the step where you are attempting to generate your executable.
Why for
sin()
in<math.h>
, do we need-lm
option explicitly; but, not forprintf()
in<stdio.h>
?
Because both these functions are implemented as part of the "Single UNIX Specification". This history of this standard is interesting, and is known by many names (IEEE Std 1003.1, X/Open Portability Guide, POSIX, Spec 1170).
This standard, specifically separates out the "Standard C library" routines from the "Standard C Mathematical Library" routines (page 277). The pertinent passage is copied below:
Standard C Library
The Standard C library is automatically searched by
cc
to resolve external references. This library supports all of the interfaces of the Base System, as defined in Volume 1, except for the Math Routines.Standard C Mathematical Library
This library supports the Base System math routines, as defined in Volume 1. The
cc
option-lm
is used to search this library.
The reasoning behind this separation was influenced by a number of factors:
The pressures that fed into the decision to put -lm
in a different library probably included, but are not limited to:
sin()
and putting it in a custom built library.In any case, it is now part of the standard to not be automatically included as part of the C language, and that's why you must add -lm
.
Checkout the -maxdepth
flag of find
find . -maxdepth 1 -type d -exec ls -ld "{}" \;
Here I used 1 as max level depth, -type d
means find only directories, which then ls -ld
lists contents of, in long format.
I'm no c++ guy, but you should be able to get the gist from this.
public static string Reverse(string s) {

char[] chars = new char[length];
for (int i = 0; i < loop; i++) {
j = length - i - 1;
chars[i] = s[j];
chars[j] = s[i];
}
return new string(chars);

Can someone help me with the exact syntax?
It's a three-step process, and it involves modifying the openssl.cnf
file. You might be able to do it with only command line options, but I don't do it that way.
Find your openssl.cnf
file. It is likely located in /usr/lib/ssl/openssl.cnf
:
$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf
On my Debian system, /usr/lib/ssl/openssl.cnf
is used by the built-in openssl
program. On recent Debian systems it is located at /etc/ssl/openssl.cnf
You can determine which openssl.cnf
is being used by adding a spurious XXX
to the file and see if openssl
chokes.
First, modify the req
parameters. Add an alternate_names
section to openssl.cnf
with the names you want to use. There are no existing alternate_names
sections, so it does not matter where you add it.
[ alternate_names ]
DNS.1 = example.com
DNS.2 = www.example.com
DNS.3 = mail.example.com
DNS.4 = ftp.example.com
Next, add the following to the existing [ v3_ca ]
section. Search for the exact string [ v3_ca ]
:
subjectAltName = @alternate_names
You might change keyUsage
to the following under [ v3_ca ]
:
keyUsage = digitalSignature, keyEncipherment
digitalSignature
and keyEncipherment
are standard fare for a server certificate. Don't worry about nonRepudiation
. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.
In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.
Second, modify the signing parameters. Find this line under the CA_default
section:
# Extension copying option: use with caution.
# copy_extensions = copy
And change it to:
# Extension copying option: use with caution.
copy_extensions = copy
This ensures the SANs are copied into the certificate. The other ways to copy the DNS names are broken.
Third, generate your self-signed certificate:
$ openssl genrsa -out private.key 3072
$ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
...
Finally, examine the certificate:
$ openssl x509 -in certificate.pem -text -noout

With Kotlin it is as simple as:
yourString.take(10)
Returns a string containing the first n characters from this string, or the entire string if this string is shorter.
Did you include "bootstrap-theme.css" files on your code?
In "bootstrap-theme.min.css" files, background-image about ".active" is existed for "navbar" (check this screenshot: http://i.imgur.com/1etLIyY.png).
It will re-declare your style code, and then it will be effected on your code.
So after you delete or re-declare them (background-image), you can use your background color style about the ".active" tag.
Check if you're really using EnvDTE reference. If not, remove it and recompile.
Consider the list below
l=[12,23,345,456,67,7,945,467]
Another trick for reversing a list may be :
l[len(l):-len(l)-1:-1] [467, 945, 7, 67, 456, 345, 23, 12]
l[:-len(l)-1:-1] [467, 945, 7, 67, 456, 345, 23, 12]
l[len(l)::-1] [467, 945, 7, 67, 456, 345, 23, 12]
For Windows:
Method 1 (Two keys pressed at a time)
Method 2 (3 keys pressed at a time)
Please note: If you press and hold Ctrl+K for more than two seconds it will start deleting text so try to be quick with it.
I use the above shortcuts, and they work on my Windows system.
The RestTemplate getForObject()
method does not support setting headers. The solution is to use the exchange()
method.
So instead of restTemplate.getForObject(url, String.class, param)
(which has no headers), use
HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...
HttpEntity entity = new HttpEntity(headers);
ResponseEntity<String> response = restTemplate.exchange(
url, HttpMethod.GET, entity, String.class, param);
Finally, use response.getBody()
to get your result.
This question is similar to this question.
You may try using services of angular js, it has worked for me..giving the code snippets below
Controller code:
$scope.total = 0;
var aCart = new CartService();
$scope.addItemToCart = function (product) {
aCart.addCartTotal(product.Price);
};
$scope.showCart = function () {
$scope.total = aCart.getCartTotal();
};
Service Code:
app.service("CartService", function () {
Total = [];
Total.length = 0;
return function () {
this.addCartTotal = function (inTotal) {
Total.push( inTotal);
}
this.getCartTotal = function () {
var sum = 0;
for (var i = 0; i < Total.length; i++) {
sum += parseInt(Total[i], 10);
}
return sum;
}
};
});
Operations with a Python list operate on the list. list1 and list2
will check if list1
is empty, and return list1
if it is, and list2
if it isn't. list1 + list2
will append list2
to list1
, so you get a new list with len(list1) + len(list2)
elements.
Operators that only make sense when applied element-wise, such as &
, raise a TypeError
, as element-wise operations aren't supported without looping through the elements.
Numpy arrays support element-wise operations. array1 & array2
will calculate the bitwise or for each corresponding element in array1
and array2
. array1 + array2
will calculate the sum for each corresponding element in array1
and array2
.
This does not work for and
and or
.
array1 and array2
is essentially a short-hand for the following code:
if bool(array1):
return array2
else:
return array1
For this you need a good definition of bool(array1)
. For global operations like used on Python lists, the definition is that bool(list) == True
if list
is not empty, and False
if it is empty. For numpy's element-wise operations, there is some disambiguity whether to check if any element evaluates to True
, or all elements evaluate to True
. Because both are arguably correct, numpy doesn't guess and raises a ValueError
when bool()
is (indirectly) called on an array.
This can be done using ServerSocket, same as on JavaSE. This class is available on Android. android.permission.INTERNET
is required.
The only more tricky part, you need a separate thread wait on the ServerSocket, servicing sub-sockets that come from its accept
method. You also need to stop and resume this thread as needed. The simplest approach seems to kill the waiting thread by closing the ServerSocket.
If you only need a server while your activity is on the top, starting and stopping ServerSocket thread can be rather elegantly tied to the activity life cycle methods. Also, if the server has multiple users, it may be good to service requests in the forked threads. If there is only one user, this may not be necessary.
If you need to tell the user on which IP is the server listening,use NetworkInterface.getNetworkInterfaces(), this question may tell extra tricks.
Finally, here there is possibly the complete minimal Android server that is very short, simple and may be easier to understand than finished end user applications, recommended in other answers.
I know this is old, but I was having this same issue, found this post, and while it didn't explain exactly what was wrong, it helped me to the right answer - so hopefully my answer helps someone else who might be having a similar problem to mine.
I had an element I wanted rotated vertical, so naturally I added the filter: for IE8 and then the -ms-transform property for IE9. What I found is that having the -ms-transform property AND the filter applied to the same element causes IE9 to render the element very poorly. My solution:
If you are using the transform-origin property, add one for MS too (-ms-transform-origin: left bottom;). If you don't see your element, it could be that it's rotating on it's middle axis and thus leaving the page somehow - so double check that.
Move the filter: property for IE7&8 to a separate style sheet and use an IE conditional to insert that style sheet for browsers less than IE9. This way it doesn't affect the IE9 styles and all should work fine.
Make sure to use the correct DOCTYPE tag as well; if you have it wrong IE9 will not work properly.
Just add the <mat-icon>
inside mat-button
or mat-raised-button
. See the example below. Note that I am using material icon instead of your svg for demo purpose:
<button mat-button>
<mat-icon>mic</mat-icon>
Start Recording
</button>
OR
<button mat-raised-button color="accent">
<mat-icon>mic</mat-icon>
Start Recording
</button>
Here is a link to stackblitz demo.
I had this problem occasionally when using a multi-label name ie test.internal
The solution for me was to stop/start the dnscache on my windows 7 machine. Open a console as administrator and type
net stop dnscache
net start dnscache
then sigh and look for a way to get a Mac as your principal desktop.
I added viewlocationformat to RazorViewEngine and worked for me.
ViewLocationFormats = new[] {
"~/Views/{1}/{0}.cshtml",
"~/Views/Shared/{0}.cshtml",
"~/Areas/Admin/Views/{1}/{0}.cshtml",
"~/Areas/Admin/Views/Shared/{0}.cshtml"
};
You can simply 'add' the arrays:
>> $a = array(1, 2, 3);
array (
0 => 1,
1 => 2,
2 => 3,
)
>> $b = array("a" => 1, "b" => 2, "c" => 3)
array (
'a' => 1,
'b' => 2,
'c' => 3,
)
>> $a + $b
array (
0 => 1,
1 => 2,
2 => 3,
'a' => 1,
'b' => 2,
'c' => 3,
)
This is a quick example
plot(rnorm(30), xlab = expression(paste("4"^"th")))
Since 2019 you can now use the new functionality called Github package registry.
Basically the process is:
settings.xml
deploy using
mvn deploy -Dregistry=https://maven.pkg.github.com/yourusername -Dtoken=yor_token
In Python 3.7, and running Windows 10 this worked (I am not sure whether it will work on other platforms and/or other versions of Python)
Replacing this line:
with open('filename', 'w') as f:
With this:
with open('filename', 'w', encoding='utf-8') as f:
The reason why it is working is because the encoding is changed to UTF-8 when using the file, so characters in UTF-8 are able to be converted to text, instead of returning an error when it encounters a UTF-8 character that is not suppord by the current encoding.
Try this code:
final File f = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());
replace 'MyClass
' with your class containing the main method.
Alternatively you can also use
System.getProperty("java.class.path")
Above mentioned System property provides
Path used to find directories and JAR archives containing class files. Elements of the class path are separated by a platform-specific character specified in the path.separator property.

As far as I know, there's a good library called localeplanet
for Localization and Internationalization in JavaScript. Furthermore, I think it's native and has no dependencies to other libraries (e.g. jQuery)
Here's the website of library: http://www.localeplanet.com/
Also look at this article by Mozilla, you can find very good method and algorithms for client-side translation: http://blog.mozilla.org/webdev/2011/10/06/i18njs-internationalize-your-javascript-with-a-little-help-from-json-and-the-server/
The common part of all those articles/libraries is that they use a i18n
class and a get
method (in some ways also defining an smaller function name like _
) for retrieving/converting the key
to the value
. In my explaining the key
means that string you want to translate and the value
means translated string.
Then, you just need a JSON document to store key
's and value
's.
For example:
var _ = document.webL10n.get;
alert(_('test'));
And here the JSON:
{ test: "blah blah" }
I believe using current popular libraries solutions is a good approach.
$('#input-field-id').val($('#input-field-id').val() + 'more text');

I also had this problem with another style of implementation but I forgot where I got it since it was 2 years ago.
static string sha256(string randomString)
{
var crypt = new SHA256Managed();
string hash = String.Empty;
byte[] crypto = crypt.ComputeHash(Encoding.ASCII.GetBytes(randomString));
foreach (byte theByte in crypto)
{
hash += theByte.ToString("x2");
}
return hash;
}
When I input something like abcdefghi2013
for some reason it gives different results and results in errors in my login module.
Then I tried modifying the code the same way as suggested by Quuxplusone and changed the encoding from ASCII
to UTF8
then it finally worked!
static string sha256(string randomString)
{
var crypt = new System.Security.Cryptography.SHA256Managed();
var hash = new System.Text.StringBuilder();
byte[] crypto = crypt.ComputeHash(Encoding.UTF8.GetBytes(randomString));
foreach (byte theByte in crypto)
{
hash.Append(theByte.ToString("x2"));
}
return hash.ToString();
}
Thanks again Quuxplusone for the wonderful and detailed answer! :)
Here is how you can check if the token exists:
if (jobject["Result"].SelectToken("Items") != null) { ... }
It checks if "Items" exists in "Result".
This is a NOT working example that causes exception:
if (jobject["Result"]["Items"] != null) { ... }
I used the url as above: http://translate.google.com/translate_tts?tl=en&q=Hello%20World

string field = e.SortExpression.Split(' ')[0];
string sort = "ASC";
if (sortField != null)
{
sort = sortField.Split(' ')[0] == field ? (sortField.Split(' ')[1] == "DESC" ? "ASC" : "DESC") : "ASC";
}
dg.Attributes["sortField"] = field + " " + sort;
data.Sort(new GenericComparer < SubreportSummary > (field, sort, null));
dg.DataSource = data;
dg.DataBind();

AFAIK you must reformat your String in ISO format to be able to cast it as a Date:
cast(concat(substr(STR_DMY,7,4), '-',
substr(STR_DMY,1,2), '-',
substr(STR_DMY,4,2)
)
as date
) as DT
To display a Date as a String with specific format, then it's the other way around, unless you have Hive 1.2+ and can use date_format()
=> did you check the documentation by the way?
I'd rather trust JDK over System property. Following is a working snippet.
private boolean checkIfStringContainsNewLineCharacters(String str){
if(!StringUtils.isEmpty(str)){
Scanner scanner = new Scanner(str);
scanner.nextLine();
boolean hasNextLine = scanner.hasNextLine();
scanner.close();
return hasNextLine;
}
return false;
}
My way is based on stream due to running on all Android versions and needs of fecthing resources such as URL/URI, any suggestion is welcome.
As far as concerned, streams (InputStream and OutputStream) transfer binary data, when developer goes to write a string to a stream, must first convert it to bytes, or in other words encode it.
public boolean writeStringToFile(File file, String string, Charset charset) {
if (file == null) return false;
if (string == null) return false;
return writeBytesToFile(file, string.getBytes((charset == null) ? DEFAULT_CHARSET:charset));
}
public boolean writeBytesToFile(File file, byte[] data) {
if (file == null) return false;
if (data == null) return false;
FileOutputStream fos;
BufferedOutputStream bos;
try {
fos = new FileOutputStream(file);
bos = new BufferedOutputStream(fos);
bos.write(data, 0, data.length);
bos.flush();
bos.close();
fos.close();
} catch (IOException e) {
e.printStackTrace();
Logger.e("!!! IOException");
return false;
}
return true;
}
It means that the field is (part of) a non-unique index. You can issue
show create table <table>;

I would use python-dpkt. Here is the documentation: http://www.commercialventvac.com/dpkt.html
This is all I know how to do though sorry.
#!/usr/local/bin/python2.7
import dpkt
counter=0
ipcounter=0
tcpcounter=0
udpcounter=0
filename='sampledata.pcap'
for ts, pkt in dpkt.pcap.Reader(open(filename,'r')):
counter+=1
eth=dpkt.ethernet.Ethernet(pkt)
if eth.type!=dpkt.ethernet.ETH_TYPE_IP:
continue
ip=eth.data
ipcounter+=1
if ip.p==dpkt.ip.IP_PROTO_TCP:
tcpcounter+=1
if ip.p==dpkt.ip.IP_PROTO_UDP:
udpcounter+=1
print "Total number of packets in the pcap file: ", counter
print "Total number of ip packets: ", ipcounter
print "Total number of tcp packets: ", tcpcounter
print "Total number of udp packets: ", udpcounter
Update:
Use .AddRange
to append any Enumrable collection to the list.
You can get the content of a MultipartFile
by using the getBytes
method and you can write to the file using Files.newOutputStream()
:
public void write(MultipartFile file, Path dir) {
Path filepath = Paths.get(dir.toString(), file.getOriginalFilename());
try (OutputStream os = Files.newOutputStream(filepath)) {
os.write(file.getBytes());
}
}
You can also use the transferTo method:
public void multipartFileToFile(
MultipartFile multipart,
Path dir
) throws IOException {
Path filepath = Paths.get(dir.toString(), multipart.getOriginalFilename());
multipart.transferTo(filepath);
}
Passing an array of items as a collapsed parameter to the WHERE..IN clause will fail since query will take form of WHERE Age IN ("11, 13, 14, 16")
.
But you can pass your parameter as an array serialized to XML or JSON:
nodes()
method:StringBuilder sb = new StringBuilder();
foreach (ListItem item in ddlAge.Items)
if (item.Selected)
sb.Append("<age>" + item.Text + "</age>"); // actually it's xml-ish
sqlComm.CommandText = @"SELECT * from TableA WHERE Age IN (
SELECT Tab.col.value('.', 'int') as Age from @Ages.nodes('/age') as Tab(col))";
sqlComm.Parameters.Add("@Ages", SqlDbType.NVarChar);
sqlComm.Parameters["@Ages"].Value = sb.ToString();
OPENXML
method:using System.Xml.Linq;
...
XElement xml = new XElement("Ages");
foreach (ListItem item in ddlAge.Items)
if (item.Selected)
xml.Add(new XElement("age", item.Text);
sqlComm.CommandText = @"DECLARE @idoc int;
EXEC sp_xml_preparedocument @idoc OUTPUT, @Ages;
SELECT * from TableA WHERE Age IN (
SELECT Age from OPENXML(@idoc, '/Ages/age') with (Age int 'text()')
EXEC sp_xml_removedocument @idoc";
sqlComm.Parameters.Add("@Ages", SqlDbType.Xml);
sqlComm.Parameters["@Ages"].Value = xml.ToString();
That's a bit more on the SQL side and you need a proper XML (with root).
OPENJSON
method (SQL Server 2016+):using Newtonsoft.Json;
...
List<string> ages = new List<string>();
foreach (ListItem item in ddlAge.Items)
if (item.Selected)
ages.Add(item.Text);
sqlComm.CommandText = @"SELECT * from TableA WHERE Age IN (
select value from OPENJSON(@Ages))";
sqlComm.Parameters.Add("@Ages", SqlDbType.NVarChar);
sqlComm.Parameters["@Ages"].Value = JsonConvert.SerializeObject(ages);
Note that for the last method you also need to have Compatibility Level at 130+.
Well we can easily get all the direct children of an element using childNodes
and we can select ancestors with a specific class with querySelectorAll
, so it's not hard to imagine we could create a new function that gets both and compares the two.
HTMLElement.prototype.queryDirectChildren = function(selector){
var direct = [].slice.call(this.directNodes || []); // Cast to Array
var queried = [].slice.call(this.querySelectorAll(selector) || []); // Cast to Array
var both = [];
// I choose to loop through the direct children because it is guaranteed to be smaller
for(var i=0; i<direct.length; i++){
if(queried.indexOf(direct[i])){
both.push(direct[i]);
}
}
return both;
}
Note: This will return an Array of Nodes, not a NodeList.
Usage
document.getElementById("myDiv").queryDirectChildren(".foo");
For length including white-space:
$("#id").val().length
For length without white-space:
$("#id").val().replace(/ /g,'').length
For removing only beginning and trailing white-space:
$.trim($("#test").val()).length
For example, the string " t e s t "
would evaluate as:
//" t e s t "
$("#id").val();
//Example 1
$("#id").val().length; //Returns 9
//Example 2
$("#id").val().replace(/ /g,'').length; //Returns 4
//Example 3
$.trim($("#test").val()).length; //Returns 7
Here is a demo using all of them.
UILabel
has a property lineBreakMode
that you can set as per your requirement.
Following on from the answer given by @Vaiden, in Xcode 8 you can resolve this issue by selecting the target and clicking the "Fix issue". Of course, you'll still need to set up push notifications in the Apple Developer portal (you can simplify the process a little by using the new "Automatically manage signing" option, which saves you the hassle of downloading the provisioning profiles).
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.
sb.Append(Environment.Newline);
sb.Append("\t");
//first find out the removed ones
List removedList = new ArrayList();
for(Object a: list){
if(a.getXXX().equalsIgnoreCase("AAA")){
logger.info("this is AAA........should be removed from the list ");
removedList.add(a);
}

I can't believe all these convoluted answers. Assuming the key is of type: string (or use 'var' if you're a lazy developer): -
List<string> listOfKeys = theCollection.Keys.ToList();
I've created a variant of https://stackoverflow.com/a/17845473/189411
where you can set min and max text size in relation of min and max size of box that you want "check" size. In addition you can check size of dom element different than box where you want apply text size.
You resize text between 19px and 25px on #size-2 element, based on 500px and 960px width of #size-2 element
resizeTextInRange(500,960,19,25,'#size-2');
You resize text between 13px and 20px on #size-1 element, based on 500px and 960px width of body element
resizeTextInRange(500,960,13,20,'#size-1','body');
complete code are there https://github.com/kiuz/sandbox-html-js-css/tree/gh-pages/text-resize-in-range-of-text-and-screen/src
function inRange (x,min,max) {
return Math.min(Math.max(x, min), max);
}
function resizeTextInRange(minW,maxW,textMinS,textMaxS, elementApply, elementCheck=0) {
if(elementCheck==0){elementCheck=elementApply;}
var ww = $(elementCheck).width();
var difW = maxW-minW;
var difT = textMaxS- textMinS;
var rapW = (ww-minW);
var out=(difT/100)*(rapW/(difW/100))+textMinS;
var normalizedOut = inRange(out, textMinS, textMaxS);
$(elementApply).css('font-size',normalizedOut+'px');
console.log(normalizedOut);
}
$(function () {
resizeTextInRange(500,960,19,25,'#size-2');
resizeTextInRange(500,960,13,20,'#size-1','body');
$(window).resize(function () {
resizeTextInRange(500,960,19,25,'#size-2');
resizeTextInRange(500,960,13,20,'#size-1','body');
});
});
Just type
document.querySelector('video').playbackRate = 1.25;
in JS console of your modern browser.
Probably the string would be like this data:image/jpeg;base64,/9j/4QN8RXh...
First split for /
and get the second token.
var StrAfterSlash = Face.Split('/')[1];
Then Split for ;
and get the first token which will be the format. In my case it's jpeg.
var ImageFormat =StrAfterSlash.Split(';')[0];
Then remove the line data:image/jpeg;base64,
for the collected format
CleanFaceData=Face.Replace($"data:image/{ImageFormat };base64,",string.Empty);
Set the UINavigationControllerDelegate and implement this delegate func (Swift):
func navigationController(navigationController: UINavigationController, willShowViewController viewController: UIViewController, animated: Bool) {
if viewController is <target class> {
//if the only way to get back - back button was pressed
}
}
I know this has been answered, but here's mine just because I think case is an under-appreciated tool. (Maybe because people think it is slow, but it's at least as fast as an if, sometimes faster.)

Whevever you get a problem like this just go to the man page for the function in question and it will tell you what header you are missing, e.g.
$ man memset
MEMSET(3) BSD Library Functions Manual MEMSET(3)
NAME
memset -- fill a byte string with a byte value
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
void *
memset(void *b, int c, size_t len);
Note that for C++ it's generally preferable to use the proper equivalent C++ headers, <cstring>
/<cstdio>
/<cstdlib>
/etc, rather than C's <string.h>
/<stdio.h>
/<stdlib.h>
/etc.
You may try with below query :
INSERT INTO errortable (dateupdated,table1id)
VALUES (to_date(to_char(sysdate,'dd/mon/yyyy hh24:mi:ss'), 'dd/mm/yyyy hh24:mi:ss' ),1083 );
To view the result of it:
SELECT to_char(hire_dateupdated, 'dd/mm/yyyy hh24:mi:ss')
FROM errortable
WHERE table1id = 1083;
For anyone coming to this that wants a linq-less way to get an element from a dictionary
var d = new Dictionary<string, string>();
d.Add("a", "b");
var e = d.GetEnumerator();
e.MoveNext();
var anElement = e.Current;
// anElement/e.Current is a KeyValuePair<string,string>
// where Key = "a", Value = "b"
I'm not sure if this is implementation specific, but if your Dictionary doesn't have any elements, Current
will contain a KeyValuePair<string, string>
where both the key and value are null
.
(I looked at the logic behind linq's First
method to come up with this, and tested it via LinqPad 4
)
I got to problem this way:
-Created console application with C#
-This appliaction using createeventsource like this
if(!System.Diagnostics.EventLog.SourceExists(sourceName)) System.Diagnostics.EventLog.CreateEventSource(sourceName,logName);
-Build solution and get .exe file
-Run exe as administator.This create log file.
NOTE: Dont remember Event viewer must be refresh for see the log.
I hope this solution helps someone :)
Try this
string stringToCheck = "text1text2text3";
string[] stringArray = new string[] { "text1" };
var t = lines.ToList().Find(c => c.Contains(stringToCheck));
It will return you the line with the first incidence of the text that you are looking for.
If you are truly dynamically setting this, you should set the .Url field of instance of the proxy class you are calling.
Setting the value in the .config file from within your program:
Is a mess;
Might not be read until the next application start.
If it is only something that needs to be done once per installation, I'd agree with the other posters and use the .config file and the dynamic setting.

Your code works fine.
def list = [["c":"d"], ["e":"f"], ["g":"h"]]
Map tmpHM = [1:"second (e:f)", 0:"first (c:d)", 2:"third (g:h)"]
for (objKey in tmpHM.keySet()) {
HashMap objHM = (HashMap) list.get(objKey);
print("objHM: ${objHM} , ")
}
prints objHM: [e:f] , objHM: [c:d] , objHM: [g:h] ,

Then click "edit in console", "execute script"
Turns out it needs to be specified via escaped unicode. This question is related and contains the answer.
The solution:
h2:after {
content: "\00a0";
}
Use conditional comments. You're trying to detect users of IE < 9 and conditional comments will work in those browsers; in other browsers (IE >= 10 and non-IE), the comments will be treated as normal HTML comments, which is what they are.
Example HTML:
<!--[if lt IE 9]>
WE DON'T LIKE YOUR BROWSER
<![endif]-->
You can also do this purely with script, if you need:
var div = document.createElement("div");
div.innerHTML = "<!--[if lt IE 9]><i></i><![endif]-->";
var isIeLessThan9 = (div.getElementsByTagName("i").length == 1);
if (isIeLessThan9) {
alert("WE DON'T LIKE YOUR BROWSER");
}
Another simple timeit example:
def your_function_to_test():
# do some stuff...
time_to_run_100_times = timeit.timeit(lambda: your_function_to_test, number=100)
I see this has been answered, but it seems like you could avoid all of this 'remapping' of the enter key by simply hooking your validation into the AcceptButton on a form. ie. you have 3 textboxes (txtA,txtB,txtC) and an 'OK' button set to be AcceptButton (and TabOrder set properly). So, if in txtA and you hit enter, if the data is invalid, your focus will stay in txtA, but if it is valid, assuming the other txts need input, validation will just put you into the next txt that needs valid input thus simulating TAB behaviour... once all txts have valid input, pressing enter will fire a succsessful validation and close form (or whatever...) Make sense?
You cannot prevent the process on the far end of a pipe from exiting, and if it exits before you've finished writing, you will get a SIGPIPE signal. If you SIG_IGN the signal, then your write will return with an error - and you need to note and react to that error. Just catching and ignoring the signal in a handler is not a good idea -- you must note that the pipe is now defunct and modify the program's behaviour so it does not write to the pipe again (because the signal will be generated again, and ignored again, and you'll try again, and the whole process could go on for a long time and waste a lot of CPU power).
Very old question but providing some additional information which may help someone else. I also encountered same error and I was using ojdbc14.jar with 12.1.0.2 Oracle Database. On Oracle official web page this information is listed that which version supports which database drivers. Here is the link and it appears that with Oracle 12c and Java 7 or 8 the correct version is ojdbc7.jar.
In the ojdbc6.jar is for 11.2.0.4.
Do you have a local user.name
or user.email
that's overriding the global one?
git config --list --global | grep user
user.name=YOUR NAME
user.email=YOUR@EMAIL
git config --list --local | grep user
user.name=YOUR NAME
user.email=
If so, remove them
git config --unset --local user.name
git config --unset --local user.email
The local settings are per-clone, so you'll have to unset the local user.name
and user.email
for each of the repos on your machine.
I think you are after this:
CONVERT(datetime, date_as_string, 103)
Notice, that datetime
hasn't any format. You think about its presentation. To get the data of datetime
in an appropriate format you can use
CONVERT(varchar, date_as_datetime, 103)
Cool.
I also found the documentation regarding the E:
http://www.postgresql.org/docs/8.3/interactive/sql-syntax-lexical.html#SQL-SYNTAX-STRINGS
PostgreSQL also accepts "escape" string constants, which are an extension to the SQL standard. An escape string constant is specified by writing the letter E (upper or lower case) just before the opening single quote, e.g. E'foo'. (When continuing an escape string constant across lines, write E only before the first opening quote.) Within an escape string, a backslash character (\) begins a C-like backslash escape sequence, in which the combination of backslash and following character(s) represents a special byte value. \b is a backspace, \f is a form feed, \n is a newline, \r is a carriage return, \t is a tab. Also supported are \digits, where digits represents an octal byte value, and \xhexdigits, where hexdigits represents a hexadecimal byte value. (It is your responsibility that the byte sequences you create are valid characters in the server character set encoding.) Any other character following a backslash is taken literally. Thus, to include a backslash character, write two backslashes (\\). Also, a single quote can be included in an escape string by writing \', in addition to the normal way of ''.
One thing I've used with good results is the following (I don't know if its mentioned already because I can't remember its name).
You precompute a table T with a random number for each character in your key's alphabet [0,255]. You hash your key 'k0 k1 k2 ... kN' by taking T[k0] xor T[k1] xor ... xor T[kN]. You can easily show that this is as random as your random number generator and its computationally very feasible and if you really run into a very bad instance with lots of collisions you can just repeat the whole thing using a fresh batch of random numbers.
date('Y-m-d', strtotime('+1 day', strtotime($date)))
Should read
date('Y-m-d', strtotime(' +1 day'))
Update to answer question asked in comment about continuously changing the date.
<?php
$date = isset($_GET['date']) ? $_GET['date'] : date('Y-m-d');
$prev_date = date('Y-m-d', strtotime($date .' -1 day'));
$next_date = date('Y-m-d', strtotime($date .' +1 day'));
?>
<a href="?date=<?=$prev_date;?>">Previous</a>
<a href="?date=<?=$next_date;?>">Next</a>
This will increase and decrease the date by one from the date you are on at the time.
The problem is that when redirecting a file into 'mail' like that, it's used for the message body only. Any headers you embed in the file will go into the body instead.
Try:
mail --append="Content-type: text/html" -s "Built notification" [email protected] < /var/www/report.csv
--append lets you add arbitrary headers to the mail, which is where you should specify the content-type and content-disposition. There's no need to embed the To
and Subject
headers in your file, or specify them with --append, since you're implicitly setting them on the command line already (-s is the subject, and [email protected] automatically becomes the To
).
You can do it with templates (or SFINAE (Substitution Failure Is Not An Error)). Example:
#include <iostream>
class base
{
public:
virtual ~base() = default;
};
template <
class type,
class = decltype(
static_cast<base*>(static_cast<type*>(0))
)
>
bool check(type)
{
return true;
}
bool check(...)
{
return false;
}
class child : public base
{
public:
virtual ~child() = default;
};
class grandchild : public child {};
int main()
{
std::cout << std::boolalpha;
std::cout << "base: " << check(base()) << '\n';
std::cout << "child: " << check(child()) << '\n';
std::cout << "grandchild: " << check(grandchild()) << '\n';
std::cout << "int: " << check(int()) << '\n';
std::cout << std::flush;
}
Output:
base: true
child: true
grandchild: true
int: false
I know this is an old post, but changing th or td color is not te right way. I was fooled by this post as well.
First load your bootstrap.css and add this in your own css. This way it is only 2 lines if you have a hovered table, else its only 1 line, unless you want to change odd and even :-)
.table-striped>tbody>tr:nth-child(odd) {
background-color: LemonChiffon;
}
.table-hover tbody tr:hover {
background-color: AliceBlue;
}
You can use PostBackUrl="~/Confirm.aspx"
For example:
In your .aspx file
<asp:Button ID="btnConfirm" runat="server" Text="Confirm"
PostBackUrl="~/Confirm.aspx" />
or in your .cs file
btnConfirm.PostBackUrl="~/Confirm.aspx"
This should do it (not tested):
animals[2...3] = []
Edit: and you need to make it a var
, not a let
, otherwise it's an immutable constant.
In my case, I needed to Edit Inbound Rules
on my AWS RDS instance to accept All Traffic
. The default TCP/IP
constraint prevented me from creating a database from my local machine otherwise.
In my model object class i ha defined the annotations like this
@Entity
@Table(name = "user_details")
public class UserDetails {
@GeneratedValue
private int userId;
private String userName;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
@Id
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
}
the issue resolved when I writing the both @Id and @GenerateValue annotation together @ the variable declaration.
@Entity
@Table(name = "user_details")
public class UserDetails {
@Id
@GeneratedValue
private int userId;
private String userName;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public int getUserId() {
return userId;
}
...
}
Hope this is helpful
There are the slideDown, slideUp, and slideToggle functions native to jquery 1.3+, and they work quite nicely...
https://api.jquery.com/category/effects/
You can use slideDown just like this:
$("test").slideDown("slow");
And if you want to combine effects and really go nuts I'd take a look at the animate function which allows you to specify a number of CSS properties to shape tween or morph into. Pretty fancy stuff, that.
I know this is a late answer but you could manually change the 7 font declarations in the latest version of Bootstrap:
html {
font-family: sans-serif;
}
body {
font-family: sans-serif;
}
pre, code, kbd, samp {
font-family: monospace;
}
input, button, select, optgroup, textarea {
font-family: inherit;
}
.tooltip {
font-family: sans-serif;
}
.popover {
font-family: sans-serif;
}
.text-monospace {
font-family: monospace;
}
Good luck.
It could be useful to change the encoding just on the command line before the file is read:
rem On MicroSoft Windows
vim --cmd "set encoding=utf-8" file.ext
# In *nix shell
vim --cmd 'set encoding=utf-8' file.ext
Duplicate question which basically says use ExecuteScalar()
instead.
VLookup
You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".
External Reference
To reference a cell of the same Workbook use the following pattern:
<Sheetname>!<Cell>
Example:
Table1!A1
To reference a cell of a different Workbook use this pattern:
[<Workbook_name>]<Sheetname>!<Cell>
Example:
[MyWorkbook]Table1!A1
If you are writing a lot of data and speed is a concern you should probably go with f.write(...)
. I did a quick speed comparison and it was considerably faster than print(..., file=f)
when performing a large number of writes.
import time
start = start = time.time()
with open("test.txt", 'w') as f:
for i in range(10000000):
# print('This is a speed test', file=f)
# f.write('This is a speed test\n')
end = time.time()
print(end - start)
On average write
finished in 2.45s on my machine, whereas print
took about 4 times as long (9.76s). That being said, in most real-world scenarios this will not be an issue.
If you choose to go with print(..., file=f)
you will probably find that you'll want to suppress the newline from time to time, or replace it with something else. This can be done by setting the optional end
parameter, e.g.;
with open("test", 'w') as f:
print('Foo1,', file=f, end='')
print('Foo2,', file=f, end='')
print('Foo3', file=f)
Whichever way you choose I'd suggest using with
since it makes the code much easier to read.
Update: This difference in performance is explained by the fact that write
is highly buffered and returns before any writes to disk actually take place (see this answer), whereas print
(probably) uses line buffering. A simple test for this would be to check performance for long writes as well, where the disadvantages (in terms of speed) for line buffering would be less pronounced.
start = start = time.time()
long_line = 'This is a speed test' * 100
with open("test.txt", 'w') as f:
for i in range(1000000):
# print(long_line, file=f)
# f.write(long_line + '\n')
end = time.time()
print(end - start, "s")
The performance difference now becomes much less pronounced, with an average time of 2.20s for write
and 3.10s for print
. If you need to concatenate a bunch of strings to get this loooong line performance will suffer, so use-cases where print
would be more efficient are a bit rare.
How can we open a new, but more importantly, how do we do stuff in that new tab?
Webdriver doesn't add a new WindowHandle for each tab, and only has control of the first tab. So, after selecting a new tab (Control + Tab Number) set .DefaultContent() on the driver to define the visible tab as the one you're going to do work on.
Dim driver = New WebDriver("Firefox", BaseUrl)
' Open new tab - send Control T
Dim body As IWebElement = driver.FindElement(By.TagName("body"))
body.SendKeys(Keys.Control + "t")
' Go to a URL in that tab
driver.GoToUrl("YourURL")
' Assuming you have m tabs open, go to tab n by sending Control + n
body.SendKeys(Keys.Control + n.ToString())
' Now set the visible tab as the drivers default content.
driver.SwitchTo().DefaultContent()
Updating lines in place in a file is not supported on most file system (a line in a file is just some data that ends with newline, the next line start just after that).
As I see it you have two options:
Small example for the first method:
from itertools import islice, izip, count
print list(islice(izip(count(1), count(2), count(3)), 10))
This will print
[(1, 2, 3), (2, 3, 4), (3, 4, 5), (4, 5, 6), (5, 6, 7), (6, 7, 8), (7, 8, 9), (8, 9, 10), (9, 10, 11), (10, 11, 12)]
even though count
generate an infinite sequence of numbers
When you
import App from './App.jsx';
That means it will import whatever you export default
. You can rename App
class inside App.jsx
to whatever you want as long as you export default
it will work but you can only have one export default.
So you only need to export default App
and you don't need to export the rest.
If you still want to export the rest of the components, you will need named export.

Check Bookmark line (if there is no Mark tab update to the current version).
Enter your search term and click Mark All
Now go to the menu Search → Bookmark → Remove Bookmarked lines
Done.
Based on the previous answers I'm using the following utility methods in case anyone would like to use it.
/**
* @param message the message to be encoded
*
* @return the enooded from of the message
*/
public static String toBase64(String message) {
byte[] data;
try {
data = message.getBytes("UTF-8");
String base64Sms = Base64.encodeToString(data, Base64.DEFAULT);
return base64Sms;
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return null;
}
/**
* @param message the encoded message
*
* @return the decoded message
*/
public static String fromBase64(String message) {
byte[] data = Base64.decode(message, Base64.DEFAULT);
try {
return new String(data, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return null;
}
This website has a concise tutorial on how to use SQL Server Management Studio. As you will see you can open a "Query Window", paste your script and run it. It does not allow you to execute scripts by using the file path. However, you can do this easily by using the command line (cmd.exe):
sqlcmd -S .\SQLExpress -i SqlScript.sql
Where SqlScript.sql
is the script file name located at the current directory. See this Microsoft page for more examples
You need to wait until the image is loaded before you draw it. Try this instead:
var canvas = document.getElementById('viewport'),
context = canvas.getContext('2d');
make_base();
function make_base()
{
base_image = new Image();
base_image.src = 'img/base.png';
base_image.onload = function(){
context.drawImage(base_image, 0, 0);
}
}
i.e. draw the image in the onload callback of the image.
Other answers work, but
To get the full/default price:
$product->get_price_html();
function trimNumber(num, len) {
const modulu_one = 1;
const start_numbers_float=2;
var int_part = Math.trunc(num);
var float_part = String(num % modulu_one);
float_part = float_part.slice(start_numbers_float, start_numbers_float+len);
return int_part+'.'+float_part;
}
I discovered that I had to include
body { width:100%; }
for "margin: 0 auto" to work for tables.
Always generate script and review before you run. Below the script
select 'Alter table dbo.' + t.name + ' drop constraint '+ d.name
from sys.tables t
join sys.default_constraints d on d.parent_object_id = t.object_id
join sys.columns c on c.object_id = t.object_id
and c.column_id = d.parent_column_id
where c.name in ('VersionEffectiveDate','VersionEndDate','VersionReasonDesc')
order by t.name
I had this problem before, and solved it according to React official page isMounted is an Antipattern.
Set a property isMounted
flag to be true in componentDidMount
, and toggle it false in componentWillUnmount
. When you setState()
in your callbacks, check isMounted
first! It works for me.
state = {
isMounted: false
}
componentDidMount() {
this.setState({isMounted: true})
}
componentWillUnmount(){
this.setState({isMounted: false})
}
callback:
if (this.state.isMounted) {
this.setState({'time': remainTimeInfo});}
Also remember you can include custom indices to the array sent to the server like this
<form method='post' id='userform' action='thisform.php'>
<tr>
<td>Trouble Type</td>
<td>
<input type='checkbox' name='checkboxvar[4]' value='Option One'>4<br>
<input type='checkbox' name='checkboxvar[6]' value='Option Two'>6<br>
<input type='checkbox' name='checkboxvar[9]' value='Option Three'>9
</td>
</tr>
<input type='submit' class='buttons'>
</form>
This is particularly useful when you want to use the id
of individual objects in a server array accounts
(for instance) to send data back to the server and recognize same at server
<form method='post' id='userform' action='thisform.php'>
<tr>
<td>Trouble Type</td>
<td>
<?php foreach($accounts as $account) { ?>
<input type='checkbox' name='accounts[<?php echo $account->id ?>]' value='<?php echo $account->name ?>'>
<?php echo $account->name ?>
<br>
<?php } ?>
</td>
</tr>
<input type='submit' class='buttons'>
</form>
<?php
if (isset($_POST['accounts']))
{
print_r($_POST['accounts']);
}
?>
Here is a while
loop:
while read filename
do
echo "Printing: $filename"
cat "$filename"
done < filenames.txt
This is an easy and quick solution when the string value is proper with the comma(,).
But if the string is with the last character with the comma, Which makes a blank array element, and this is also removed extra spaces around it.
"123,234,345,"
So I suggest using push()
var arr = [], str="123,234,345,"
str.split(",").map(function(item){
if(item.trim()!=''){arr.push(item.trim())}
})
Try this:
$.ajax({
type: 'get',
url: 'manageproducts.do',
data: 'option=1',
success: function(data) {
availableProductNames = data.split(",");
alert(availableProductNames);
}
});
Also You have a few errors in your sample code, not sure if that was causing the error or it was just a typo upon entering the question.
If you wish to download a version of a file, you need to use get_object

someone here may find it useful. hhb_curl_exec2 works pretty much like curl_exec, but arg3 is an array which will be populated with the returned http headers (numeric index), and arg4 is an array which will be populated with the returned cookies ($cookies["expires"]=>"Fri, 06-May-2016 05:58:51 GMT"), and arg5 will be populated with... info about the raw request made by curl.
the downside is that it requires CURLOPT_RETURNTRANSFER to be on, else it error out, and that it will overwrite CURLOPT_STDERR and CURLOPT_VERBOSE, if you were already using them for something else.. (i might fix this later)
example of how to use it:
<?php
header("content-type: text/plain;charset=utf8");
$ch=curl_init();
$headers=array();
$cookies=array();
$debuginfo="";
$body="";
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);

var_dump('$cookies:',$cookies,'$headers:',$headers,'$debuginfo:',$debuginfo,'$body:',$body);

Also, no need to escape the :

You may find that using the `group' aes will help you get the result you want. For example:
tu <- expand.grid(Land = gl(2, 1, labels = c("DE", "BB")),
Altersgr = gl(5, 1, labels = letters[1:5]),
Geschlecht = gl(2, 1, labels = c('m', 'w')),
Jahr = 2000:2009)
set.seed(42)
tu$Wert <- unclass(tu$Altersgr) * 200 + rnorm(200, 0, 10)
ggplot(tu, aes(x = Jahr, y = Wert, color = Altersgr, group = Altersgr)) +
geom_point() + geom_line() +
facet_grid(Geschlecht ~ Land)
Which produces the plot found here:
If you want a pure CSS solution, this trick works very well - use the transform object. This also works with images when they're cached or not:
CSS:
.main_container{
position: relative;
width: 500px;
height: 300px;
background-color: #cccccc;
}
.center_horizontally{
position: absolute;
width: 100px;
height: 100px;
background-color: green;
left: 50%;
top: 0;
transform: translate(-50%,0);
}
.center_vertically{
position: absolute;
top: 50%;
left: 0;
width: 100px;
height: 100px;
background-color: blue;
transform: translate(0,-50%);
}
.center{
position: absolute;
top: 50%;
left: 50%;
width: 100px;
height: 100px;
background-color: red;
transform: translate(-50%,-50%);
}
HTML:
<div class="main_container">
<div class="center_horizontally"></div>
<div class="center_vertically"></div>
<div class="center"></div>
</div>
</div

ApplicationContext.getInstance().toast("I am toast");
Add below code in Application class accordingly.
public class ApplicationContext extends Application {
private static ApplicationContext instance;
@Override
public void onCreate() {
super.onCreate();
instance = this;
}
public static void toast(String message) {
Toast.makeText(getContext(), message, Toast.LENGTH_SHORT).show();
}
}
Here's a solution to the general case that doesn't involve needing to know the length of the array ahead of time, using collect
, or using udf
s. Unfortunately this only works for spark
version 2.1 and above, because it requires the posexplode
function.
Suppose you had the following DataFrame:
df = spark.createDataFrame(
[
[1, 'A, B, C, D'],
[2, 'E, F, G'],
[3, 'H, I'],
[4, 'J']
]
, ["num", "letters"]
)
df.show()
#+---+----------+
#|num| letters|
#+---+----------+
#| 1|A, B, C, D|
#| 2| E, F, G|
#| 3| H, I|
#| 4| J|
#+---+----------+
Split the letters
column and then use posexplode
to explode the resultant array along with the position in the array. Next use pyspark.sql.functions.expr
to grab the element at index pos
in this array.
import pyspark.sql.functions as f
df.select(
"num",
f.split("letters", ", ").alias("letters"),
f.posexplode(f.split("letters", ", ")).alias("pos", "val")
)\
.show()
#+---+------------+---+---+
#|num| letters|pos|val|
#+---+------------+---+---+
#| 1|[A, B, C, D]| 0| A|
#| 1|[A, B, C, D]| 1| B|
#| 1|[A, B, C, D]| 2| C|
#| 1|[A, B, C, D]| 3| D|
#| 2| [E, F, G]| 0| E|
#| 2| [E, F, G]| 1| F|
#| 2| [E, F, G]| 2| G|
#| 3| [H, I]| 0| H|
#| 3| [H, I]| 1| I|
#| 4| [J]| 0| J|
#+---+------------+---+---+
Now we create two new columns from this result. First one is the name of our new column, which will be a concatenation of letter
and the index in the array. The second column will be the value at the corresponding index in the array. We get the latter by exploiting the functionality of pyspark.sql.functions.expr
which allows us use column values as parameters.
df.select(
"num",
f.split("letters", ", ").alias("letters"),
f.posexplode(f.split("letters", ", ")).alias("pos", "val")
)\
.drop("val")\
.select(
"num",
f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
f.expr("letters[pos]").alias("val")
)\
.show()
#+---+-------+---+
#|num| name|val|
#+---+-------+---+
#| 1|letter0| A|
#| 1|letter1| B|
#| 1|letter2| C|
#| 1|letter3| D|
#| 2|letter0| E|
#| 2|letter1| F|
#| 2|letter2| G|
#| 3|letter0| H|
#| 3|letter1| I|
#| 4|letter0| J|
#+---+-------+---+
Now we can just groupBy
the num
and pivot
the DataFrame. Putting that all together, we get:
df.select(
"num",
f.split("letters", ", ").alias("letters"),
f.posexplode(f.split("letters", ", ")).alias("pos", "val")
)\
.drop("val")\
.select(
"num",
f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
f.expr("letters[pos]").alias("val")
)\
.groupBy("num").pivot("name").agg(f.first("val"))\
.show()
#+---+-------+-------+-------+-------+
#|num|letter0|letter1|letter2|letter3|
#+---+-------+-------+-------+-------+
#| 1| A| B| C| D|
#| 3| H| I| null| null|
#| 2| E| F| G| null|
#| 4| J| null| null| null|
#+---+-------+-------+-------+-------+
Try escaping the slash: someString.replace(/\//g, "-");
By the way - /
is a (forward-)slash; \
is a backslash.
You could read Google answer for it here: http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml#Preincrement_and_Predecrement
So, main point is, what no difference for simple object, but for iterators and other template objects you should use preincrement.
EDITED:
There are no difference because you use simple type, so no side effects, and post- or preincrements executed after loop body, so no impact on value in loop body.
You could check it with such a loop:
for (int i = 0; i < 5; cout << "we still not incremented here: " << i << endl, i++)
{
cout << "inside loop body: " << i << endl;
}
You cannot override a function with different parameters, only you are allowed to change the functionality of the overridden method.

No, you can't instantite an abstract class.We instantiate only anonymous class.In abstract class we declare abstract methods and define concrete methods only.
for whom wants to do this in kotlin:
val timer = fixedRateTimer(period = 1000L) {
val currentTime: Date = Calendar.getInstance().time
runOnUiThread {
tvFOO.text = currentTime.toString()
}
}
for stopping the timer you can use this:
timer.cancel()
this function has many other options, give it a try
If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user
, picked from your example), then the syntax is quite simple:
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin('a.user', 'u')
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
Since you are applying a condition on the joined result here, using a LEFT JOIN
or simply JOIN
is the same.
If no association is available, then the query looks like following
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin(
'User\Entity\User',
'u',
\Doctrine\ORM\Query\Expr\Join::WITH,
'a.user = u.id'
)
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
This will produce a resultset that looks like following:
array(
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
// ...
)
I got this error when I was trying to get the current position (MediaPlayer.getCurrentPosition()) of media player when it wasn't in the prepared stated. I got around this by Keeping track of its state and only calling the getCurrentPosition() method after onPreparedListener is called.
you can develop it through two ways
def compareVariables(x,y,z):
mylist = []
if x==0 or y==0 or z==0:
mylist.append('c')
if x==1 or y==1 or z==1:

if x==2 or y==2 or z==2:
mylist.append('e')
if x==3 or y==3 or z==3:
mylist.append('f')
else:
print("wrong input value!")
print('first:',mylist)
compareVariables(1, 3, 2)
Or
def compareVariables(x,y,z):
mylist = []
if 0 in (x,y,z):
mylist.append('c')
if 1 in (x,y,z):
mylist.append('d')
if 2 in (x,y,z):

print('second:',mylist)
compareVariables(1, 3, 2)

The following is a complete example based on JeeBee's post, using java enum's instead of using a custom method.
Note that in Java SE 7 and later you can use a String object in the switch statement's expression instead.
public class Main {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
String current = args[0];
Days currentDay = Days.valueOf(current.toUpperCase());
switch (currentDay) {
case MONDAY:
case TUESDAY:
case WEDNESDAY:
System.out.println("boring");
break;
case THURSDAY:
System.out.println("getting better");
case FRIDAY:
case SATURDAY:
case SUNDAY:
System.out.println("much better");
break;
}
}
public enum Days {
MONDAY,
TUESDAY,
WEDNESDAY,
THURSDAY,
FRIDAY,
SATURDAY,
SUNDAY
}
}
Yes, it's easy and possible. Define first default colors.
Console.BackgroundColor = ConsoleColor.Black;
Console.ForegroundColor = ConsoleColor.White;
Console.Clear();
Console.Clear()
it's important in order to set new console colors. If you don't make this step you can see combined colors when ask for values with Console.ReadLine()
.
Then you can change the colors on each print:
Console.BackgroundColor = ConsoleColor.Black;
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine("Red text over black.");
When finish your program, remember reset console colors on finish:
Console.ResetColor();
Console.Clear();
Now with netcore we have another problem if you want to "preserve" the User experience because terminal have different colors on each Operative System.
I'm making a library that solves this problem with Text Format: colors, alignment and lot more. Feel free to use and contribute.

I could see $.ajax
is removed from jQuery slim 3.2.1
From the jQuery docs
You can also use the slim build, which excludes the ajax and effects modules
Below is the comment from the slim version with the features removed
/*! jQuery v3.2.1 -ajax,-ajax/jsonp,-ajax/load,-ajax/parseXML,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-event/ajax,-effects,-effects/Tween,-effects/animatedSelector | (c) JS Foundation and other contributors | jquery.org/license */
You can use the cd
builtin, or the pushd
and popd
builtins for this purpose. For example:
# do something with /etc as the working directory
cd /etc
:
# do something with /tmp as the working directory
cd /tmp
:
You use the builtins just like any other command, and can change directory context as many times as you like in a script.
With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.
Ruby has a line by line loop over input files (the '-n' flag) from the commandline so it can be used like AWK. This Ruby one-liner:
ruby -ne 'END {puts $.}'
will count lines like the AWK one-liner:
awk 'END{print NR}'
Ruby gets feature this through Perl, which took it from AWK as a way of getting sysadmins on board with Perl without having to change the way they do things.
I know this is a little old, but I recently came across this while looking for a similar solution. Relying on hover events isn't good for responsive design, and especially terrible on mobile/touch screens. I ended up making a small edit to the dropdown.js file the allows you to click the menu item to open the menu and if you click the menu item again it will follow it.
The nice thing about this is it doesn't rely on hover at all and so it still works really nicely on a touch screen.
I've posted it here: https://github.com/mrhanlon/twbs-dropdown-doubletap/blob/master/js/dropdown-doubletap.js
Hope that helps!
I agree with Cat Plus Plus's answer. However, if you know this will only be used on Unix-like OSes, you can use external calls to the shell commands mkdir
, chmod
, and chown
. Make sure to pass extra flags to recursively affect directories:
>>> import subprocess
>>> subprocess.check_output(['mkdir', '-p', 'first/second/third'])
# Equivalent to running 'mkdir -p first/second/third' in a shell (which creates
# parent directories if they do not yet exist).
>>> subprocess.check_output(['chown', '-R', 'dail:users', 'first'])
# Recursively change owner to 'dail' and group to 'users' for 'first' and all of
# its subdirectories.
>>> subprocess.check_output(['chmod', '-R', 'g+w', 'first'])
# Add group write permissions to 'first' and all of its subdirectories.
EDIT I originally used commands
, which was a bad choice since it is deprecated and vulnerable to injection attacks. (For example, if a user gave input to create a directory called first/;rm -rf --no-preserve-root /;
, one could potentially delete all directories).
EDIT 2 If you are using Python less than 2.7, use check_call
instead of check_output
. See the subprocess
documentation for details.
stop-service -inputobject $(get-service -ComputerName remotePC -Name Spooler)
This fails because of your variables
-ComputerName remotePC
needs to be a variable $remotePC
or a string "remotePC"
-Name Spooler
(same thing for spooler)
This is how I managed to set it up with express:
var fs = require( 'fs' );
var app = require('express')();
var https = require('https');
var server = https.createServer({
key: fs.readFileSync('./test_key.key'),
cert: fs.readFileSync('./test_cert.crt'),
ca: fs.readFileSync('./test_ca.crt'),
requestCert: false,
rejectUnauthorized: false
},app);
server.listen(8080);
var io = require('socket.io').listen(server);
io.sockets.on('connection',function (socket) {
...
});
app.get("/", function(request, response){
...
})
I hope that this will save someone's time.
Update : for those using lets encrypt use this
var server = https.createServer({
key: fs.readFileSync('privkey.pem'),
cert: fs.readFileSync('fullchain.pem')
},app);
Make sure you're editing the right httpd.conf
file, then the error about unreliable server's domain name should be gone (this is the most common mistake).
To locate your httpd.conf
Apache configuration file, run:
apachectl -t -D DUMP_INCLUDES
Then edit the file and uncomment or change ServerName
line into:
ServerName localhost
Then restart your apache by: sudo apachectl restart

The answer by Christopher Parker is correct but outdated. The troublesome old date-time classes such as java.util.Date
, java.util.Calendar
, and java.text.SimpleTextFormat
are now legacy, supplanted by the java.time classes.
Parse the input string as a date-time object, then generate a new String object in the desired format.
The LocalDate
class represents a date-only value without time-of-day and without time zone.
DateTimeFormatter fIn = DateTimeFormatter.ofPattern( "dd/MM/uuuu" , Locale.UK ); // As a habit, specify the desired/expected locale, though in this case the locale is irrelevant.
LocalDate ld = LocalDate.parse( "23/01/2017" , fIn );
Define another formatter for the output.
DateTimeFormatter fOut = DateTimeFormatter.ofPattern( "uuuu/MM/dd" , Locale.UK );
String output = ld.format( fOut );
2017/01/23
By the way, consider using standard ISO 8601 formats for strings representing date-time values.
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
UPDATE: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes. This section here is left for the sake of history.
For fun, here is his code adapted for using the Joda-Time library.
// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.
// import org.joda.time.*;
// import org.joda.time.format.*;
final String OLD_FORMAT = "dd/MM/yyyy";
final String NEW_FORMAT = "yyyy/MM/dd";
// August 12, 2010
String oldDateString = "12/08/2010";
String newDateString;
DateTimeFormatter formatterOld = DateTimeFormat.forPattern(OLD_FORMAT);
DateTimeFormatter formatterNew = DateTimeFormat.forPattern(NEW_FORMAT);
LocalDate localDate = formatterOld.parseLocalDate( oldDateString );
newDateString = formatterNew.print( localDate );
Dump to console…
System.out.println( "localDate: " + localDate );
System.out.println( "newDateString: " + newDateString );
When run…
localDate: 2010-08-12
newDateString: 2010/08/12
I made the mistake of including both:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
and:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
in the above order. So when I took out the second permission, (READ), the problem went away.
You could use jOOQ for the job. You don't have to use all of jOOQ's features to take advantage of some useful JDBC extensions. In this case, simply write:
String json = DSL.using(connection).fetch(resultSet).formatJSON();
Relevant API methods used are:
DSLContext.fetch(ResultSet)
to convert a JDBC ResultSet into a jOOQ Result.Result.formatJSON()
to format the jOOQ Result into a JSON String.The resulting formatting will look like this:
{"fields":[{"name":"field-1","type":"type-1"},
{"name":"field-2","type":"type-2"},
...,
{"name":"field-n","type":"type-n"}],
"records":[[value-1-1,value-1-2,...,value-1-n],
[value-2-1,value-2-2,...,value-2-n]]}
You could also create your own formatting rather easily, through Result.map(RecordMapper)
This essentially does the same as your code, circumventing the generation of JSON objects, "streaming" directly into a StringBuilder
. I'd say that the performance overhead should be negligible in both cases, though.
(Disclaimer: I work for the company behind jOOQ)
Of course, you don't have to use your middleware to map JDBC ResultSets to JSON. The question doesn't mention for which SQL dialect this needs to be done, but many support standard SQL/JSON syntax, or something similar, e.g.
Oracle
SELECT json_arrayagg(json_object(*))
FROM t
SQL Server
SELECT *
FROM t
FOR JSON AUTO
PostgreSQL
SELECT to_jsonb(array_agg(t))
FROM t
The final
keyword on a method parameter means absolutely nothing to the caller. It also means absolutely nothing to the running program, since its presence or absence doesn't change the bytecode. It only ensures that the compiler will complain if the parameter variable is reassigned within the method. That's all. But that's enough.
Some programmers (like me) think that's a very good thing and use final
on almost every parameter. It makes it easier to understand a long or complex method (though one could argue that long and complex methods should be refactored.) It also shines a spotlight on method parameters that aren't marked with final
.
This means that a TCP RST was received and the connection is now closed. This occurs when a packet is sent from your end of the connection but the other end does not recognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection.
This can happen if the other side crashes and then comes back up or if it calls close()
on the socket while there is data from you in transit, and is an indication to you that some of the data that you previously sent may not have been received.
It is up to you whether that is an error; if the information you were sending was only for the benefit of the remote client then it may not matter that any final data may have been lost. However you should close the socket and free up any other resources associated with the connection.
A Bcrypt hash can be stored in a BINARY(40)
column.
BINARY(60)
, as the other answers suggest, is the easiest and most natural choice, but if you want to maximize storage efficiency, you can save 20 bytes by losslessly deconstructing the hash. I've documented this more thoroughly on GitHub: https://github.com/ademarre/binary-mcf
Bcrypt hashes follow a structure referred to as modular crypt format (MCF). Binary MCF (BMCF) decodes these textual hash representations to a more compact binary structure. In the case of Bcrypt, the resulting binary hash is 40 bytes.
Gumbo did a nice job of explaining the four components of a Bcrypt MCF hash:
$<id>$<cost>$<salt><digest>
Decoding to BMCF goes like this:
$<id>$
can be represented in 3 bits.<cost>$
, 04-31, can be represented in 5 bits. Put these together for 1 byte.1 + 16 + 23

Using split()
Snippet :
var data =$('#date').text();_x000D_
var arr = data.split('/');_x000D_
$("#date").html("<span>"+arr[0] + "</span></br>" + arr[1]+"/"+arr[2]);
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="date">23/05/2013</div>
_x000D_
When you split this string --->
23/05/2013
on /
var myString = "23/05/2013";
var arr = myString.split('/');
you'll get an array of size 3
arr[0] --> 23
arr[1] --> 05
arr[2] --> 2013
I won't repeat the usual stuff about Using or freeing un-managed resources, that has all been covered. But I would like to point out what seems a common misconception.
Given the following code
Public Class LargeStuff Implements IDisposable Private _Large as string() 'Some strange code that means _Large now contains several million long strings. Public Sub Dispose() Implements IDisposable.Dispose _Large=Nothing End Sub
I realise that the Disposable implementation does not follow current guidelines, but hopefully you all get the idea.
Now, when Dispose is called, how much memory gets freed?
Answer: None.
Calling Dispose can release unmanaged resources, it CANNOT reclaim managed memory, only the GC can do that. Thats not to say that the above isn't a good idea, following the above pattern is still a good idea in fact. Once Dispose has been run, there is nothing stopping the GC re-claiming the memory that was being used by _Large, even though the instance of LargeStuff may still be in scope. The strings in _Large may also be in gen 0 but the instance of LargeStuff might be gen 2, so again, memory would be re-claimed sooner.
There is no point in adding a finaliser to call the Dispose method shown above though. That will just DELAY the re-claiming of memory to allow the finaliser to run.
If you already installed "MongoDB", if you accidentally exit from the MongoDB server, then "restart your system".
This method solved me...
[On Windows only]
And also another method is there:
press:
Windows + R
type:
services.msc
and click "ok", it opens "services" window, and then search for "MongoDB Server" in the list. After you find "MongoDB Server", right-click and choose "start" from the pop-up menu.
The MongoDb Server will start running.
Hope it works!!
Check the return value of find
against end
.
map<int, Bar>::iterator it = m.find('2');
if ( m.end() != it ) {
// contains
...
}
It's because you have:
def readTTable(fname):
try:
without a matching except
block after the try:
block. Every try
must have at least one matching except
.
See the Errors and Exceptions section of the Python tutorial.
In Objective-C you could do this by
float xpoint = (((atan2((newPoint.x - oldPoint.x) , (newPoint.y - oldPoint.y)))*180)/M_PI);

Forget aboves for vscode exclude search pattern, try to below pattern it is working for any folder in vscode last version!
!../../../locales/*
for example i have searched like below vscode example clude settings
files to include: *.js
files to exclude: **/node_modules,!../../../locales/,!../../../theme/,!../../admin/client/*
Can't do DDL over a dblink.
You can use linq:
var q = from tag in Week orderby Convert.ToDateTime(tag.date) select tag;
List<cTag> Sorted = q.ToList()
In my ROM, it's stored in the "global" database, rather than "secure". So D__'s answer is correct, but the sql line needs to connect to a different database:
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
update global set value=1 where name='wifi_on';
Similarly along the lines of these answers written as a plugin:
$.fn.sum = function () {
var sum = 0;
this.each(function () {
sum += 1*($(this).val());
});
return sum;
};
For the record 1 * x is faster than Number(x) in Chrome
For Java Application servers such as Weblogic
1) Make sure your weblogic.xml file is free of errors
like this one:
<?xml version = '1.0' encoding = 'windows-1252'?>
<weblogic-web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/weblogic-web-app http://www.bea.com/ns/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd"
xmlns="http://www.bea.com/ns/weblogic/weblogic-web-app">
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
<context-root>MyWebApp</context-root>
</weblogic-web-app>
2) Add a mime type for javascript to your web.xml file:
...
</servlet-mapping>
<mime-mapping>
<extension>js</extension>
<mime-type>application/javascript</mime-type>
</mime-mapping>
<welcome-file-list>
...
This will also work for other Java containers - Tomcat etc. application/javascript
is currently the only valid mime-type; others like text/javascript
have been deprecated.
3) You may need to clear up your browser cache or hit CTRL-F5
I would go for closing the php tag and then output the <pre></pre>
as html, so PHP doesn't have to process it before echoing it:
?>
<pre><?=print_r($arr,1)?></pre>
<?php
That should also be faster (not notable for this short piece) in general. Using can be used as shortcode for PHP code.
Use JSON.
In the following example $php_variable
can be any PHP variable.
<script type="text/javascript">
var obj = <?php echo json_encode($php_variable); ?>;
</script>
In your code, you could use like the following:
drawChart(600/50, <?php echo json_encode($day); ?>, ...)
In cases where you need to parse out an object from JSON-string (like in an AJAX request), the safe way is to use JSON.parse(..)
like the below:
var s = "<JSON-String>";
var obj = JSON.parse(s);
I came up with a simple placeholder JQuery script that allows a custom color and uses a different behavior of clearing inputs when focused. It replaces the default placeholder in Firefox and Chrome and adds support for IE8.
// placeholder script IE8, Chrome, Firefox
// usage: <input type="text" placeholder="some str" />
$(function () {
var textColor = '#777777'; //custom color
$('[placeholder]').each(function() {
(this).attr('tooltip', $(this).attr('placeholder')); //buffer
if ($(this).val() === '' || $(this).val() === $(this).attr('placeholder')) {
$(this).css('color', textColor).css('font-style','italic');
$(this).val($(this).attr('placeholder')); //IE8 compatibility
}
$(this).attr('placeholder',''); //disable default behavior
$(this).on('focus', function() {
if ($(this).val() === $(this).attr('tooltip')) {
$(this).val('');
}
});
$(this).on('keydown', function() {
$(this).css('font-style','normal').css('color','#000');
});
$(this).on('blur', function() {
if ($(this).val() === '') {
$(this).val($(this).attr('tooltip')).css('color', textColor).css('font-style','italic');
}
});
});
});
