has bad performance; it tries to read the file into memory all at once.
C# (.NET) file reader reads each line one by one
Best Performace
foreach($line in [System.IO.File]::ReadLines("C:\path\to\file.txt"))
{
$line
}
Or slightly less performant
[System.IO.File]::ReadLines("C:\path\to\file.txt") | ForEach-Object {

The foreach
statement will likely be slightly faster than ForEach-Object
(see comments below for more information).
The “Perl variable types” section of the perlintro documentation contains
The special variable
$#array
tells you the index of the last element of an array:print $mixed[$#mixed]; # last element, prints 1.23
You might be tempted to use
$#array + 1
to tell you how many items there are in an array. Don’t bother. As it happens, using@array
where Perl expects to find a scalar value (“in scalar context”) will give you the number of elements in the array:if (@animals < 5) { ... }
The perldata documentation also covers this in the “Scalar values” section.
If you evaluate an array in scalar context, it returns the length of the array. (Note that this is not true of lists, which return the last value, like the C comma operator, nor of built-in functions, which return whatever they feel like returning.) The following is always true:
scalar(@whatever) == $#whatever + 1;
Some programmers choose to use an explicit conversion so as to leave nothing to doubt:
$element_count = scalar(@whatever);
Earlier in the same section documents how to obtain the index of the last element of an array.
The length of an array is a scalar value. You may find the length of array
@days
by evaluating$#days
, as incsh
. However, this isn’t the length of the array; it’s the subscript of the last element, which is a different value since there is ordinarily a 0th element.
Use global
keyword:
#Creating global variable
glob_var=0
def use():
#Accessing global variable
global glob_var
#Changing value of global variable
glob_var=2
def show():
#Showing value of global variable
print(glob_var)
if __name__=='__main__':
use()

Simply \newpage
or \pagebreak
will work, e.g.
hello world

\pagebreak
```{r, echo=FALSE}
plot(1:10)
```
This solution assumes you are knitting PDF. For HTML, you can achieve a similar effect by adding a tag <P style="page-break-before: always">
. Note that you likely won't see a page break in your browser (HTMLs don't have pages per se), but the printing layout will have it.
Microsoft windows vista and 7 use NCSI (Network Connectivity Status Indicator) technic:
++i
is slightly more efficient due to its semantics:
++i; // Fetch i, increment it, and return it
i++; // Fetch i, copy it, increment i, return copy
For int-like indices, the efficiency gain is minimal (if any). For iterators and other heavier-weight objects, avoiding that copy can be a real win (particularly if the loop body doesn't contain much work).
As an example, consider the following loop using a theoretical BigInteger class providing arbitrary precision integers (and thus some sort of vector-like internals):
std::vector<BigInteger> vec;
for (BigInteger i = 0; i < 99999999L; i++) {
vec.push_back(i);
}
That i++ operation includes copy construction (i.e. operator new, digit-by-digit copy) and destruction (operator delete) for a loop that won't do anything more than essentially make one more copy of the index object. Essentially you've doubled the work to be done (and increased memory fragmentation most likely) by simply using the postfix increment where prefix would have been sufficient.
I have got a same question like you, I use wireshark to capture my sent TCP packets, I found when I use mysql
bin to connect the remote host, it connects remote's 3307 port, that's my falut in /etc/mysql/my.cnf
, 3307 is another project mysql port, but I change that config in my.cnf
[client] part, when I use -P
option to specify 3306 port, it's OK.
From here:
SELECT *
INTO new_table_name [IN externaldatabase]
FROM old_tablename
** PHP >= 5.5
simply u can use this
$key = array_search(40489, array_column($userdb, 'uid'));
Let's suppose this multi dimensional array:
$userdb=Array
(
(0) => Array
(
(uid) => '100',
(name) => 'Sandra Shush',
(url) => 'urlof100'
),
(1) => Array
(
(uid) => '5465',
(name) => 'Stefanie Mcmohn',
(pic_square) => 'urlof100'
),
(2) => Array
(
(uid) => '40489',
(name) => 'Michael',
(pic_square) => 'urlof40489'
)
);
$key = array_search(40489, array_column($userdb, 'uid'));
In my case it was because I had another folder that contained xampp and all it's files (htdocs, php e.t.c). Like I installed Xampp twice in different directories and for some reason the configurations of the other one was affecting my current xampp directory and so I had to change the memory size in the php.ini file of the other directory too.
Well, it's not a single statement, but it's about as close as you can get with oracle:
BEGIN
FOR R IN (SELECT owner, table_name FROM all_tables WHERE owner='TheOwner') LOOP
EXECUTE IMMEDIATE 'grant select on '||R.owner||'.'||R.table_name||' to TheUser';
END LOOP;
END;
Without knowing your compiler, no one can give you specific, step by step instructions, but the basic procedure is as follows:
Specify the path which should be searched in order to find the actual library (usually under Library Search Paths, Library Directories, etc. in the properties page)
Under linker options, specify the actual name of the library. In VS, you would write Allegro.lib (or whatever it is), on Linux you usually just write Allegro (prefixes/suffixes are added automatically in most cases). This is usually under "Libraries->Input", just "Libraries", or something similar.
Ensure that you have included the headers for the library and make sure that they can be found (similar process to that listed in step #1 and #2). If it is a static library, you should be good; if it's a DLL, you need to copy it in your project.
Mash the build button.
Custom Comparator
should help
Collections.sort(list, new Comparator<String>() {
@Override
public int compare(String s1, String s2) {
return s1.compareToIgnoreCase(s2);
}
});
Or if you are using Java 8:
list.sort(String::compareToIgnoreCase);
if(!localStorage.hash) localStorage.hash = "thinkdj";
Or
var secret = localStorage.hash || 42;
There are three options, that you can use. -I
is to exclude binary files in grep. Other are for line numbers and file names.
grep -I -n -H
-I -- process a binary file as if it did not contain matching data;
-n -- prefix each line of output with the 1-based line number within its input file
-H -- print the file name for each match
So this might be a way to run grep:
grep -InH your-word *
If you don't need the leading and trailing spaces :
str.Trim().Length
What I do when it happens is Disable the COM port into the Device Manager and Enable it again.
It stop the communications with another program or thread and become free for you.
I hope this works for you. Regards.
For ASP.Net core Just add the following to your Startup Class:
JsonConvert.DefaultSettings = (() =>
{
var settings = new JsonSerializerSettings();
settings.Converters.Add(new StringEnumConverter { AllowIntegerValues = false });
return settings;
});
also happens when you use jinja templates (which have different syntax for calling object methods) and you forget to set it in settings.py
Why so complex?
$('#id:checked').val();
Will work just fine!
If you don't want to use a watcher, you can do something like this:
<input type='checkbox' ng-init='checkStatus=false' ng-model='checkStatus' ng-click='doIfChecked(checkStatus)'>
You can convert a number to a string with n decimal places using the SPRINTF command:
>> x = 1.23; >> sprintf('%0.6f', x) ans = 1.230000 >> x = 1.23456789; >> sprintf('%0.6f', x) ans = 1.234568
The LayoutInflater class is used to instantiate the contents of layout XML files into their corresponding View objects.
In other words, it takes an XML file as input and builds the View objects from it.
Package distance includes Levenshtein distance:
import distance
distance.levenshtein("lenvestein", "levenshtein")
# 3
Or you can just use <input onclick="select()">
Works perfect.
You're running bundle exec
on a program. The program's creators wrote it when certain versions of gems were available. The program Gemfile specifies the versions of the gems the creators decided to use. That is, the script was made to run correctly against these gem versions.
Your system-wide Gemfile may differ from this Gemfile. You may have newer or older gems with which this script doesn't play nice. This difference in versions can give you weird errors.
bundle exec
helps you avoid these errors. It executes the script using the gems specified in the script's Gemfile rather than the systemwide Gemfile. It executes the certain gem versions with the magic of shell aliases.
See more on the man page.
Here's an example Gemfile:
source 'http://rubygems.org'
gem 'rails', '2.8.3'
Here, bundle exec
would execute the script using rails version 2.8.3 and not some other version you may have installed system-wide.
You are using the incorrect overload of ActionLink. Try this

UIAlertController *alertController;
UIAlertAction *destroyAction;
UIAlertAction *otherAction;
alertController = [UIAlertController alertControllerWithTitle:nil
message:nil
preferredStyle:UIAlertControllerStyleActionSheet];
destroyAction = [UIAlertAction actionWithTitle:@"Remove All Data"

handler:^(UIAlertAction *action) {
// do destructive stuff here
}];
otherAction = [UIAlertAction actionWithTitle:@"Blah"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction *action) {
// do something here
}];
// note: you can control the order buttons are shown, unlike UIActionSheet
[alertController addAction:destroyAction];
[alertController addAction:otherAction];
[alertController setModalPresentationStyle:UIModalPresentationPopover];
UIPopoverPresentationController *popPresenter = [alertController
popoverPresentationController];
popPresenter.sourceView = button;
popPresenter.sourceRect = button.bounds;
[self presentViewController:alertController animated:YES completion:nil];

The easiest way to add these headers is a .htaccess
file that adds some configuration to your server. If the assets are hosted on a server that you don't control, there's nothing you can do about it.
Note that some hosting providers will not let you use .htaccess
files, so check their terms if it doesn't seem to work.
The HTML5Boilerplate project has an excellent .htaccess
file that covers the necessary settings. See the relevant part of the file at their Github repository

This will grab records with strings (in the fieldName column) that are 10 characters long:
select * from table where length(fieldName)=10
The solution lies in understanding these two keyword arguments:
usecols
) using column names rather than integer indices.So because you have a header row, passing header=0
is sufficient and additionally passing names
appears to be confusing pd.read_csv
.
Removing names
from the second call gives the desired output:
import pandas as pd
from StringIO import StringIO
csv = r"""dummy,date,loc,x
bar,20090101,a,1
bar,20090102,a,3
bar,20090103,a,5
bar,20090101,b,1
bar,20090102,b,3
bar,20090103,b,5"""
df = pd.read_csv(StringIO(csv),
header=0,
index_col=["date", "loc"],
usecols=["date", "loc", "x"],
parse_dates=["date"])
Which gives us:
x
date loc
2009-01-01 a 1
2009-01-02 a 3
2009-01-03 a 5
2009-01-01 b 1

you can use IQKeyboardManager library to do this. it handle every thing, you don't need any additional setup.IQKeyboardManager is available through CocoaPods, to install it simply add the following line to your Podfile:
pod 'IQKeyboardManager'
or Just drag and drop IQKeyBoardManager directory from demo project to your project. That's it. you can find IQKeyBoardManager directory from https://github.com/hackiftekhar/IQKeyboardManager
Possible duplicate: Is there a maven 2 archetype for spring 3 MVC applications?
That said, I would encourage you to think about making your own archetype. The reason is, no matter what you end up getting from someone else's, you can do better in not that much time, and a decent sized Java project is going to end up making a lot of jar projects.
There are multiple ways to calculate the distance based on the coordinates i.e latitude and longitude
from geopy import distance
from math import sin, cos, sqrt, atan2, radians
from sklearn.neighbors import DistanceMetric
import osrm
import numpy as np
lat1, lon1, lat2, lon2, R = 20.9467,72.9520, 21.1702, 72.8311, 6373.0
coordinates_from = [lat1, lon1]
coordinates_to = [lat2, lon2]
dlon = radians(lon2) - radians(lon1)
dlat = radians(lat2) - radians(lat1)
a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
c = 2 * atan2(sqrt(a), sqrt(1 - a))
distance_haversine_formula = R * c
print('distance using haversine formula: ', distance_haversine_formula)
dist = DistanceMetric.get_metric('haversine')
X = [[radians(lat1), radians(lon1)], [radians(lat2), radians(lon2)]]
distance_sklearn = R * dist.pairwise(X)
print('distance using sklearn: ', np.array(distance_sklearn).item(1))
osrm_client = osrm.Client(host='http://router.project-osrm.org')
coordinates_osrm = [[lon1, lat1], [lon2, lat2]] # note that order is lon, lat
osrm_response = osrm_client.route(coordinates=coordinates_osrm, overview=osrm.overview.full)
dist_osrm = osrm_response.get('routes')[0].get('distance')/1000 # in km
print('distance using OSRM: ', dist_osrm)
distance_geopy = distance.distance(coordinates_from, coordinates_to).km
print('distance using geopy: ', distance_geopy)
distance_geopy_great_circle = distance.great_circle(coordinates_from, coordinates_to).km
print('distance using geopy great circle: ', distance_geopy_great_circle)

You can use beforeShowDay to do this
The following example disables dates 14 March 2013 thru 16 March 2013
var array = ["2013-03-14","2013-03-15","2013-03-16"]
$('input').datepicker({

var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
return [ array.indexOf(string) == -1 ]
}
});

This is whole story how date problem was and how Big DBMSs handled these problems.
During the period between 1 A.D. and today, the Western world has actually used two main calendars: the Julian calendar of Julius Caesar and the Gregorian calendar of Pope Gregory XIII. The two calendars differ with respect to only one rule: the rule for deciding what a leap year is. In the Julian calendar, all years divisible by four are leap years. In the Gregorian calendar, all years divisible by four are leap years, except that years divisible by 100 (but not divisible by 400) are not leap years. Thus, the years 1700, 1800, and 1900 are leap years in the Julian calendar but not in the Gregorian calendar, while the years 1600 and 2000 are leap years in both calendars.
When Pope Gregory XIII introduced his calendar in 1582, he also directed that the days between October 4, 1582, and October 15, 1582, should be skipped—that is, he said that the day after October 4 should be October 15. Many countries delayed changing over, though. England and her colonies didn't switch from Julian to Gregorian reckoning until 1752, so for them, the skipped dates were between September 4 and September 14, 1752. Other countries switched at other times, but 1582 and 1752 are the relevant dates for the DBMSs that we're discussing.
Thus, two problems arise with date arithmetic when one goes back many years. The first is, should leap years before the switch be calculated according to the Julian or the Gregorian rules? The second problem is, when and how should the skipped days be handled?
This is how the Big DBMSs handle these questions:
- Pretend there was no switch. This is what the SQL Standard seems to require, although the standard document is unclear: It just says that dates are "constrained by the natural rules for dates using the Gregorian calendar"—whatever "natural rules" are. This is the option that DB2 chose. When there is a pretence that a single calendar's rules have always applied even to times when nobody heard of the calendar, the technical term is that a "proleptic" calendar is in force. So, for example, we could say that DB2 follows a proleptic Gregorian calendar.
- Avoid the problem entirely. Microsoft and Sybase set their minimum date values at January 1, 1753, safely past the time that America switched calendars. This is defendable, but from time to time complaints surface that these two DBMSs lack a useful functionality that the other DBMSs have and that the SQL Standard requires.
- Pick 1582. This is what Oracle did. An Oracle user would find that the date-arithmetic expression October 15 1582 minus October 4 1582 yields a value of 1 day (because October 5–14 don't exist) and that the date February 29 1300 is valid (because the Julian leap-year rule applies). Why did Oracle go to extra trouble when the SQL Standard doesn't seem to require it? The answer is that users might require it. Historians and astronomers use this hybrid system instead of a proleptic Gregorian calendar. (This is also the default option that Sun picked when implementing the GregorianCalendar class for Java—despite the name, GregorianCalendar is a hybrid calendar.)

Can't copy the icons here, but here are the descriptions:
Show: Present the content in the detail or master area depending on the content of the screen.
If the app is displaying a master and detail view, the content is pushed onto the detail area. If the app is only displaying the master or the detail, the content is pushed on top of the current view controller stack.
Show Detail: Present the content in the detail area.
If the app is displaying a master and detail view, the new content replaces the current detail. If the app is only displaying the master or the detail, the content replaces the top of the current view controller stack.
Present Modally: Present the content modally.
Present as Popover: Present the content as a popover anchored to an existing view.
Custom: Create your own behaviors by using a custom segue.
This will give you the result you're giving as an example:

Pointer-events can be disabled for a parent element (probably transparent div) and yet be enabled for child elements.
This is helpful if you work with multiple overlapping div layers, where you want to be able click the child elements of any layer. For this all parenting divs get pointer-events: none
and click-children get pointer-events reenabled by pointer-events: all

You can follow the .selectedIndex strategy of danielrmt, but determine the index based on the text within the option tags like this:
$('#dropdown')[0].selectedIndex = $('#dropdown option').toArray().map(jQuery.text).indexOf('B');
This works on the original HTML without using value attributes.

<strong>Requires a number.</strong></span>
<span class="alert-error" ng-show="form['QTY' + $index].$error.required">
<strong>*Required</strong></span>
</td>
we have to show the ng-show in ng-pattern

<span class="alert-error" ng-show="form['QTY' + $index].$error.required">
If I start with a 3x4 array, and concatenate a 3x1 array, with axis 1, I get a 3x5 array:
In [911]: x = np.arange(12).reshape(3,4)
In [912]: np.concatenate([x,x[:,-1:]], axis=1)
Out[912]:
array([[ 0, 1, 2, 3, 3],
[ 4, 5, 6, 7, 7],
[ 8, 9, 10, 11, 11]])
In [913]: x.shape,x[:,-1:].shape
Out[913]: ((3, 4), (3, 1))
Note that both inputs to concatenate have 2 dimensions.
Omit the :
, and x[:,-1]
is (3,) shape - it is 1d, and hence the error:
In [914]: np.concatenate([x,x[:,-1]], axis=1)
...
ValueError: all the input arrays must have same number of dimensions
The code for np.append
is (in this case where axis is specified)
return concatenate((arr, values), axis=axis)
So with a slight change of syntax append
works. Instead of a list it takes 2 arguments. It imitates the list append
is syntax, but should not be confused with that list method.
In [916]: np.append(x, x[:,-1:], axis=1)
Out[916]:
array([[ 0, 1, 2, 3, 3],
[ 4, 5, 6, 7, 7],
[ 8, 9, 10, 11, 11]])
np.hstack
first makes sure all inputs are atleast_1d
, and then does concatenate:
return np.concatenate([np.atleast_1d(a) for a in arrs], 1)
So it requires the same x[:,-1:]
input. Essentially the same action.
np.column_stack
also does a concatenate on axis 1. But first it passes 1d inputs through
array(arr, copy=False, subok=True, ndmin=2).T
This is a general way of turning that (3,) array into a (3,1) array.
In [922]: np.array(x[:,-1], copy=False, subok=True, ndmin=2).T
Out[922]:
array([[ 3],
[ 7],
[11]])
In [923]: np.column_stack([x,x[:,-1]])
Out[923]:
array([[ 0, 1, 2, 3, 3],
[ 4, 5, 6, 7, 7],
[ 8, 9, 10, 11, 11]])
All these 'stacks' can be convenient, but in the long run, it's important to understand dimensions and the base np.concatenate
. Also know how to look up the code for functions like this. I use the ipython
??
magic a lot.
And in time tests, the np.concatenate
is noticeably faster - with a small array like this the extra layers of function calls makes a big time difference.
You have to replace the values one by one such as in a for-loop or copying another array over another such as using memcpy(..)
or std::copy
e.g.
for (int i = 0; i < arrayLength; i++) {
array[i] = newValue[i];
}
Take care to ensure proper bounds-checking and any other checking that needs to occur to prevent an out of bounds problem.
create two files e.g standard_funcs.js
and main.js
1.) standard_funcs.js
// Declaration --------------------------------------
module.exports =
{
add,
subtract
// ...
}
// Implementation ----------------------------------
function add(x, y)
{
return x + y;
}
function subtract(x, y)
{
return x - y;
}
// ...
2.) main.js
// include ---------------------------------------
const sf= require("./standard_funcs.js")
// use -------------------------------------------
var x = sf.add(4,2);
console.log(x);
var y = sf.subtract(4,2);
console.log(y);
output

Try to use the new '@supports' feature, here is one good hack that you might like:
* UPDATE!!! * Microsoft Edge and Safari 9 both added support for the @supports feature in Fall 2015, Firefox also -- so here is my updated version for you:
/* Chrome 29+ (Only) */
@supports (-webkit-appearance:none) and (not (overflow:-webkit-marquee))
and (not (-ms-ime-align:auto)) and (not (-moz-appearance:none)) {
.selector { color:red; }
}
More info on this here (the reverse... Safari but not Chrome): [ is there a css hack for safari only NOT chrome? ]
The previous CSS Hack [before Edge and Safari 9 or newer Firefox versions]:
/* Chrome 28+ (now also Microsoft Edge, Firefox, and Safari 9+) */
@supports (-webkit-appearance:none) { .selector { color:red; } }
This worked for (only) chrome, version 28 and newer.
(The above chrome 28+ hack was not one of my creations. I found this on the web and since it was so good I sent it to BrowserHacks.com recently, there are others coming.)
August 17th, 2014 update: As I mentioned, I have been working on reaching more versions of chrome (and many other browsers), and here is one I crafted that handles chrome 35 and newer.
/* Chrome 35+ */
_::content, _:future, .selector:not(*:root) { color:red; }
In the comments below it was mentioned by @BoltClock about future, past, not... etc... We can in fact use them to go a little farther back in Chrome history.
So then this is one that also works but not 'Chrome-only' which is why I did not put it here. You still have to separate it by a Safari-only hack to complete the process. I have created css hacks to do this however, not to worry. Here are a few of them, starting with the simplest:
/* Chrome 26+, Safari 6.1+ */
_:past, .selector:not(*:root) { color:red; }
Or instead, this one which goes back to Chrome 22 and newer, but Safari as well...
/* Chrome 22+, Safari 6.1+ */
@media screen and (-webkit-min-device-pixel-ratio:0)
and (min-resolution:.001dpcm),
screen and(-webkit-min-device-pixel-ratio:0)
{
.selector { color:red; }
}
The block of Chrome versions 22-28 (more complicated but works nicely) are also possible to target via a combination I worked out:
/* Chrome 22-28 (Only!) */
@media screen and(-webkit-min-device-pixel-ratio:0)
{
.selector {-chrome-:only(;
color:red;
);}
}
Now follow up with this next couple I also created that targets Safari 6.1+ (only) in order to still separate Chrome and Safari. Updated to include Safari 8
/* Safari 6.1-7.0 */
@media screen and (-webkit-min-device-pixel-ratio:0) and (min-color-index:0)
{
.selector {(; color:blue; );}
}
/* Safari 7.1+ */
_::-webkit-full-page-media, _:future, :root .selector { color:blue; }
So if you put one of the Chrome+Safari hacks above, and then the Safari 6.1-7 and 8 hacks in your styles sequentially, you will have Chrome items in red, and Safari items in blue.

window.addEventListener("scroll",function(){
window.lastScrollTime = new Date().getTime()
});
function is_scrolling() {
return window.lastScrollTime && new Date().getTime() < window.lastScrollTime + 500
}
Change the 500 to the number of milliseconds after the last scroll event at which you consider the user to be "no longer scrolling".
(addEventListener
is better than onScroll
because the former can coexist nicely with any other code that uses onScroll
.)
Something like the following will allow for multiple transitions simultaneously:
-webkit-transition: color .2s linear, text-shadow .2s linear;
-moz-transition: color .2s linear, text-shadow .2s linear;
-o-transition: color .2s linear, text-shadow .2s linear;
transition: color .2s linear, text-shadow .2s linear;

I would use the yattag library. I think it's the most pythonic way:
from yattag import Doc
doc, tag, text = Doc().tagtext()
with tag('food'):
with tag('name'):
text('French Breakfast')
with tag('price', currency='USD'):
text('6.95')
with tag('ingredients'):
for ingredient in ('baguettes', 'jam', 'butter', 'croissants'):
with tag('ingredient'):
text(ingredient)
print(doc.getvalue())

I'm using XAMPP 1.6.7 on Windows 7. This article worked for me.
I added the following lines in the file httpd-vhosts.conf
at C:/xampp/apache/conf/extra
.
I had also uncommented the line # NameVirtualHost *:80
<VirtualHost mysite.dev:80>
DocumentRoot "C:/xampp/htdocs/mysite"
ServerName mysite.dev
ServerAlias mysite.dev
<Directory "C:/xampp/htdocs/mysite">
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
After restarting the apache, it were still not working.
Then I had to follow the step 9 mentioned in the article by editing the file C:/Windows/System32/drivers/etc/hosts
.
# localhost name resolution is handled within DNS itself.
127.0.0.1 localhost
::1 localhost
127.0.0.1 mysite.dev
Then I got working http://mysite.dev

There's a property for that:
a.m_title {
text-transform: capitalize;
}
If your links can contain multiple words and you only want the first letter of the first word to be uppercase, use :first-letter
with a different transform instead (although it doesn't really matter). Note that in order for :first-letter
to work your a
elements need to be block containers (which can be display: block
, display: inline-block
, or any of a variety of other combinations of one or more properties):
a.m_title {
display: block;
}
a.m_title:first-letter {
text-transform: uppercase;
}
Here is a Python 3, POSIX solution (not Windows!) that uses mmap
to map the object into memory.
import hashlib
import mmap
def sha256sum(filename):
h = hashlib.sha256()
with open(filename, 'rb') as f:
with mmap.mmap(f.fileno(), 0, prot=mmap.PROT_READ) as mm:
h.update(mm)
return h.hexdigest()
You could try to use anchorScroll.
So the controller would be:
app.controller('MainCtrl', function($scope, $location, $anchorScroll, $routeParams) {
$scope.scrollTo = function(id) {
$location.hash(id);
$anchorScroll();
}
});
And the view:
<a href="" ng-click="scrollTo('foo')">Scroll to #foo</a>
...and no secret for the anchor id:
<div id="foo">
This is #foo
</div>
while($row = mysql_fetch_assoc($result)) {
echo $row['type'];
}
Based on the Worker objects methods mentioned in other answers, I decided to see if I could expand on the solution to invoke more threads - in this case the optimal number the machine can run and spin up multiple workers with indeterminate completion times. To do this I still need to subclass QThread - but only to assign a thread number and to 'reimplement' the signals 'finished' and 'started' to include their thread number.
I've focused quite a bit on the signals between the main gui, the threads, and the workers.
Similarly, others answers have been a pains to point out not parenting the QThread but I don't think this is a real concern. However, my code also is careful to destroy the QThread objects.
However, I wasn't able to parent the worker objects so it seems desirable to send them the deleteLater() signal, either when the thread function is finished or the GUI is destroyed. I've had my own code hang for not doing this.
Another enhancement I felt was necessary was was reimplement the closeEvent of the GUI (QWidget) such that the threads would be instructed to quit and then the GUI would wait until all the threads were finished. When I played with some of the other answers to this question, I got QThread destroyed errors.
Perhaps it will be useful to others. I certainly found it a useful exercise. Perhaps others will know a better way for a thread to announce it identity.

From laravel doc 5.2 https://laravel.com/docs/5.2/queries#ordering-grouping-limit-and-offset
skip / take
To limit the number of results returned from the query, or to skip a given number of results in the query (OFFSET), you may use the skip and take methods:
$users = DB::table('users')->skip(10)->take(5)->get();
In laravel 5.3 you can write (https://laravel.com/docs/5.3/queries#ordering-grouping-limit-and-offset)
$products = $art->products->offset(0)->limit(10)->get();

How to determine one year from now in Javascript by JP DeVries
new Date(new Date().setFullYear(new Date().getFullYear() + 1))

new Date(new Date().setFullYear(new Date().getFullYear() + nr_years))
REST APIs must be hypertext-driven
From Roy Fielding's blog here's a set of ways to check if you're building a HTTP API or a REST API:
API designers, please note the following rules before calling your creation a REST API:
- A REST API should not be dependent on any single communication protocol, though its successful mapping to a given protocol may be dependent on the availability of metadata, choice of methods, etc. In general, any protocol element that uses a URI for identification must allow any URI scheme to be used for the sake of that identification. [Failure here implies that identification is not separated from interaction.]
- A REST API should not contain any changes to the communication protocols aside from filling-out or fixing the details of underspecified bits of standard protocols, such as HTTP’s PATCH method or Link header field. Workarounds for broken implementations (such as those browsers stupid enough to believe that HTML defines HTTP’s method set) should be defined separately, or at least in appendices, with an expectation that the workaround will eventually be obsolete. [Failure here implies that the resource interfaces are object-specific, not generic.]
- A REST API should spend almost all of its descriptive effort in defining the media type(s) used for representing resources and driving application state, or in defining extended relation names and/or hypertext-enabled mark-up for existing standard media types. Any effort spent describing what methods to use on what URIs of interest should be entirely defined within the scope of the processing rules for a media type (and, in most cases, already defined by existing media types). [Failure here implies that out-of-band information is driving interaction instead of hypertext.]
- A REST API must not define fixed resource names or hierarchies (an obvious coupling of client and server). Servers must have the freedom to control their own namespace. Instead, allow servers to instruct clients on how to construct appropriate URIs, such as is done in HTML forms and URI templates, by defining those instructions within media types and link relations. [Failure here implies that clients are assuming a resource structure due to out-of band information, such as a domain-specific standard, which is the data-oriented equivalent to RPC’s functional coupling].
- A REST API should never have “typed” resources that are significant to the client. Specification authors may use resource types for describing server implementation behind the interface, but those types must be irrelevant and invisible to the client. The only types that are significant to a client are the current representation’s media type and standardized relation names. [ditto]
- A REST API should be entered with no prior knowledge beyond the initial URI (bookmark) and set of standardized media types that are appropriate for the intended audience (i.e., expected to be understood by any client that might use the API). From that point on, all application state transitions must be driven by client selection of server-provided choices that are present in the received representations or implied by the user’s manipulation of those representations. The transitions may be determined (or limited by) the client’s knowledge of media types and resource communication mechanisms, both of which may be improved on-the-fly (e.g., code-on-demand). [Failure here implies that out-of-band information is driving interaction instead of hypertext.]
You missed break statements. Don't forget to use break
-statements even in the default
case.

terribly late but i just encountered this issue and this is my fix:
private static String removeNonUtf8CompliantCharacters( final String inString ) {
if (null == inString ) return null;
byte[] byteArr = inString.getBytes();
for ( int i=0; i < byteArr.length; i++ ) {
byte ch= byteArr[i];
// remove any characters outside the valid UTF-8 range as well as all control characters
// except tabs and new lines
if ( !( (ch > 31 && ch < 253 ) || ch == '\t' || ch == '\n' || ch == '\r') ) {
byteArr[i]=' ';
}
}
return new String( byteArr );
}
For completeness, it's worth mentioning there's a decent handling of empty collections in Freemarker since recently.
So the most convenient way to iterate a map is:
<#list tags>
<ul class="posts">
<#items as tagName, tagCount>
<li>{$tagName} (${tagCount})</li>
</#items>
</ul>
<#else>
<p>No tags found.</p>
</#list>
No more <#if ...>
wrappers.
The problem is that you aren't correctly escaping the input string, try:
echo "\"member\":\"time\"" | grep -e "member\""
Alternatively, you can use unescaped double quotes within single quotes:
echo '"member":"time"' | grep -e 'member"'
It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd'
).
Iterate through the entrySet()
like so:
public static void printMap(Map mp) {
Iterator it = mp.entrySet().iterator();
while (it.hasNext()) {
Map.Entry pair = (Map.Entry)it.next();
System.out.println(pair.getKey() + " = " + pair.getValue());
it.remove(); // avoids a ConcurrentModificationException
}
}

calendar1.set(Calendar.AM_PM, 0);
calendar1.set(Calendar.HOUR, 0);

calendar1.set(Calendar.SECOND, 0);

Do this for other instances to which you want to compare. This logic worked for me; I had to compare the dates whether they are equal or not, but you can do different comparisons (before, after, equals, etc.)
So the query I was assigned to optimize was written with two CTEs in SQL server. It was taking 28sec.
I spent two minutes converting them to temp tables and the query took 3 seconds
I added an index to the temp table on the field it was being joined on and got it down to 2 seconds
Three minutes of work and now its running 12x faster all by removing CTE. I personally will not use CTEs ever they are tougher to debug as well.
The crazy thing is the CTEs were both only used once and still putting an index on them proved to be 50% faster.
If I am understanding well, if what you want to do is to export dependencies during the compilation phase so there will be no need to retrieve manually each needed libraries, you can use the mojo copy-dependencies.
Hope it can be useful in your case (examples)
You could try:
$rows = array();
while($row = mysql_fetch_array($result)){
array_push($rows, $row);
}
echo json_encode($rows);
You need to use anchors to match the beginning of the string ^
and the end of the string $
^[0-9]{2}$
Try doing this:
npm install bootstrap jquery popper.js --save

How about this page from Microsoft Connect (explaining the DesignData and DesignDataWithDesignTimeCreatableTypes) types. Quoting:
The following describes the two Build Actions for Sample Data files.
Sample data .xaml files must be assigned one of the below Build Actions:
DesignData: Sample data types will be created as faux types. Use this Build Action when the sample data types are not creatable or have read-only properties that you want to defined sample data values for.
DesignDataWithDesignTimeCreatableTypes: Sample data types will be created using the types defined in the sample data file. Use this Build Action when the sample data types are creatable using their default empty constructor.
Not so incredibly exhaustive, but it at least gives a hint. This MSDN walkthrough also gives some ideas. I don't know whether these Build Actions are applicable for non-Silverlight projects also.
Here is a method I used and worked for me
public static String toSql(Session session, Criteria criteria){
String sql="";
Object[] parameters = null;
try{
CriteriaImpl c = (CriteriaImpl) criteria;
SessionImpl s = (SessionImpl)c.getSession();
SessionFactoryImplementor factory = (SessionFactoryImplementor)s.getSessionFactory();
String[] implementors = factory.getImplementors( c.getEntityOrClassName() );
CriteriaLoader loader = new CriteriaLoader((OuterJoinLoadable)factory.getEntityPersister(implementors[0]), factory, c, implementors[0], s.getEnabledFilters());
Field f = OuterJoinLoader.class.getDeclaredField("sql");
f.setAccessible(true);
sql = (String)f.get(loader);
Field fp = CriteriaLoader.class.getDeclaredField("traslator");
fp.setAccessible(true);
CriteriaQueryTranslator translator = (CriteriaQueryTranslator) fp.get(loader);
parameters = translator.getQueryParameters().getPositionalParameterValues();
}
catch(Exception e){
throw new RuntimeException(e);
}
if (sql !=null){
int fromPosition = sql.indexOf(" from ");
sql = "SELECT * "+ sql.substring(fromPosition);
if (parameters!=null && parameters.length>0){
for (Object val : parameters) {
String value="%";
if(val instanceof Boolean){
value = ((Boolean)val)?"1":"0";
}else if (val instanceof String){
value = "'"+val+"'";
}
sql = sql.replaceFirst("\\?", value);
}
}
}
return sql.replaceAll("left outer join", "\nleft outer join").replace(" and ", "\nand ").replace(" on ", "\non ");
}
My requirements included:
My solution in the end was to use SimpleJson(https://github.com/facebook-csharp-sdk/simple-json).
Although you can install it via a nuget package, I included just that single SimpleJson.cs file (with the MIT license) in my project and referenced it.
I hope this helps someone.
I had moved my log4j.properties into the resources folder and it worked fine for me !
Getters and setters are used to implement two of the fundamental aspects of Object Oriented Programming which are:
Suppose we have an Employee class:
package com.highmark.productConfig.types;
public class Employee {
private String firstName;
private String middleName;
private String lastName;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getMiddleName() {
return middleName;
}
public void setMiddleName(String middleName) {
this.middleName = middleName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getFullName(){
return this.getFirstName() + this.getMiddleName() + this.getLastName();
}
}
Here the implementation details of Full Name is hidden from the user and is not accessible directly to the user, unlike a public attribute.
Code to To remove ipad safari: disable scrolling, and bounce effect
document.addEventListener("touchmove", function (e) {
e.preventDefault();
}, { passive: false });
If you have canvas tag inside document, sometime it will affect the usability of object inside Canvas(example: movement of object); so add below code to fix it.
document.getElementById("canvasId").addEventListener("touchmove", function (e) {
e.stopPropagation();
}, { passive: false });
To pass a NULL to MySQL, you do just that.
INSERT INTO table (field,field2) VALUES (NULL,3)
So, in your code, check if $intLat, $intLng
are empty
, if they are, use NULL
instead of '$intLat'
or '$intLng'
.
$intLat = !empty($intLat) ? "'$intLat'" : "NULL";
$intLng = !empty($intLng) ? "'$intLng'" : "NULL";
$query = "INSERT INTO data (notes, id, filesUploaded, lat, lng, intLat, intLng)
VALUES ('$notes', '$id', TRIM('$imageUploaded'), '$lat', '$long',

You can do it like... Just give the proper path of your json file...
<!doctype html>
<html>
<head>
<script type="text/javascript" src="abc.json"></script>
<script type="text/javascript" >
function load() {
var mydata = JSON.parse(data);
alert(mydata.length);
var div = document.getElementById('data');
for(var i = 0;i < mydata.length; i++)
{
div.innerHTML = div.innerHTML + "<p class='inner' id="+i+">"+ mydata[i].name +"</p>" + "<br>";
}
}
</script>
</head>
<body onload="load()">
<div id= "data">
</div>
</body>
</html>
Simply getting the data and appending it to a div... Initially printing the length in alert.
Here is my Json file: abc.json
data = '[{"name" : "Riyaz"},{"name" : "Javed"},{"name" : "Arun"},{"name" : "Sunil"},{"name" : "Rahul"},{"name" : "Anita"}]';
void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
Button b = (Button)e.CommandSource;
b.CommandArgument = ((GridViewRow)sender).RowIndex.ToString();
}
Just add below lines to your /etc/phpmyadmin/config.inc.php
file in the bottom:
$i++;
$cfg['Servers'][$i]['host'] = 'HostName:port'; //provide hostname and port if other than default
$cfg['Servers'][$i]['user'] = 'userName'; //user name for your remote server
$cfg['Servers'][$i]['password'] = 'Password'; //password
$cfg['Servers'][$i]['auth_type'] = 'config'; // keep it as config
You will get Current Server:
drop down with both 127.0.0.1
and one what you have provided with $cfg['Servers'][$i]['host']
can switch between the servers.

To expand on this (even though it is an older question); It is not not about the MySQL space itself probably, but about space in general, assuming for tmp files or something like that. My mysql data dir was not full, the / (root) partition was
The accepted answer was correct up until July 2011. To get the latest version, including the Service Pack you should find the latest version as described here:
For example, if you check the SP2 CTP and SP1, you'll find the latest version of SQL Server Management Studio under SP1:
Download the 32-bit (x86) or 64-bit (x64) version of the SQLManagementStudio*.exe files as appropriate and install it. You can find out whether your system is 32-bit or 64-bit by right clicking Computer, selecting Properties and looking at the System Type.
Although you could apply the service pack to the base version that results from following the accepted answer, it's easier to just download the latest version of SQL Server Management Studio and simply install it in one step.
This type of behavior is not supported in Java. However, if you have a large project that needs this, consider blending in Groovy code in your project. Groovy code is compiled into byte code and can be run with JVM. The company I work for uses Groovy to write service classes and Java to write everything else.
trim()
will remove all leading and trailing blanks. But be aware: Your string isn't changed. trim()
will return a new string instance instead.
The behaviour differs depending on whether the target file name already exists or not. It's usually a safety mechanism, and there are at least 3 different cases:
In this case svn mv
should work as follows:
$ svn mv old_file_name new_file_name
A new_file_name
D old_file_name
$ svn stat
A + new_file_name
> moved from old_file_name
D old_file_name
> moved to new_file_name
$ svn commit
Adding new_file_name
Deleting old_file_name
Committing transaction...
In this case, the target file needs to be removed explicitly, before the source file can be renamed. This can be done in the same transaction as follows:
$ svn mv old_file_name new_file_name
svn: E155010: Path 'new_file_name' is not a directory
$ svn rm new_file_name
D new_file_name
$ svn mv old_file_name new_file_name
A new_file_name
D old_file_name
$ svn stat
R + new_file_name
> moved from old_file_name
D old_file_name
> moved to new_file_name
$ svn commit
Replacing new_file_name
Deleting old_file_name
Committing transaction...
In the output of svn stat
, the R
indicates that the file has been replaced, and that the file has a history.
In this case, the content of the local file would be lost. If that's okay, then the file can be removed locally before renaming the existing file.
$ svn mv old_file_name new_file_name
svn: E155010: Path 'new_file_name' is not a directory
$ rm new_file_name
$ svn mv old_file_name new_file_name
A new_file_name
D old_file_name
$ svn stat
A + new_file_name
> moved from old_file_name
D old_file_name
> moved to new_file_name
$ svn commit
Adding new_file_name
Deleting old_file_name
Committing transaction...

Since 2019, Array.prototype.flatMap is good option.
options.flatMap(o => o.assigned ? [o.name] : []);
From the MDN page linked above:
flatMap
can be used as a way to add and remove items (modify the number of items) during a map. In other words, it allows you to map many items to many items (by handling each input item separately), rather than always one-to-one. In this sense, it works like the opposite of filter. Simply return a 1-element array to keep the item, a multiple-element array to add items, or a 0-element array to remove the item.
Not directly an answer, but good to know nevertheless: After indenting, please make sure that the parser(s) and application(s) which will subsequently process the formatted XML will not yield different results. White space is often significant in XML and most conforming parsers bubble it up to the application.
Use tokenGroups:
DirectorySearcher ds = new DirectorySearcher();
ds.Filter = String.Format("(&(objectClass=user)(sAMAccountName={0}))", username);
SearchResult sr = ds.FindOne();
DirectoryEntry user = sr.GetDirectoryEntry();
user.RefreshCache(new string[] { "tokenGroups" });
for (int i = 0; i < user.Properties["tokenGroups"].Count; i++) {
SecurityIdentifier sid = new SecurityIdentifier((byte[]) user.Properties["tokenGroups"][i], 0);
NTAccount nt = (NTAccount)sid.Translate(typeof(NTAccount));
//do something with the SID or name (nt.Value)
}
Note: this only gets security groups
pls try this,
$('#select_id option[value="'+value+'"]').attr("disabled", true);
There's also terms query which should save you some work. Here example from docs:
{
"terms" : {
"tags" : [ "blue", "pill" ],
"minimum_should_match" : 1
}
}
Under hood it constructs boolean should. So it's basically the same thing as above but shorter.
There's also a corresponding terms filter.
So to summarize your query could look like this:
{
"filtered": {
"query": {
"match": { "title": "hello world" }
},
"filter": {
"terms": {
"tags": ["c", "d"]
}
}
}
}
With greater number of tags this could make quite a difference in length.
I would like to share my thoughts as well, since I've bumped into the same issue.
Well, just answering the question would be:
1 - Add an extenssion to the observable collection class like this:
namespace YourNameSpace
{
public static class ObservableCollectionExtension
{
public static void OrderByReference<T>(this ObservableCollection<T> collection, List<T> comparison)
{
for (int i = 0; i < comparison.Count; i++)
{
if (!comparison.ElementAt(i).Equals(collection.ElementAt(i)))
collection.Move(collection.IndexOf(comparison[i]), i);
}
}
public static void InsertInPlace<T>(this ObservableCollection<T> collection, List<T> comparison, T item)
{
int index = comparison.IndexOf(item);
comparison.RemoveAt(index);
collection.OrderByReference(comparison);
collection.Insert(index, item);
}
}
}
2 - Then use it like this:
_animals.OrderByReference(_animals.OrderBy(x => x).ToList());
This changes your ObservableCollection, you can use linq and it doesn't change the bindings!
Extra:
I've extended @Marco and @Contango answers to my own liking. First I thought of using a list directly as the comparison, so you would have this:
public static void OrderByReference<T>(this ObservableCollection<T> collection, List<T> comparison)
{
for (int i = 0; i < comparison.Count; i++)
{
collection.Move(collection.IndexOf(comparison[i]), i);
}
}
And using like this:
YourObservableCollection.OrderByReference(YourObservableCollection.DoYourLinqOrdering().ToList());
Then I've thought, since this always move everything and triggers the move in the ObservableCollection why not compare if the object is already in there, and this brings what I've put in the begining with the Equals comparator.
Adding the object to the correct place also sounded good, but I wanned a simple way to do it. So I've came up with that:
public static void InsertInPlace<T>(this ObservableCollection<T> collection, List<T> comparison, T item)
{
collection.Insert(comparison.IndexOf(item), item);
}
You send a list with the new object where you want and also this new object, so you need to create a list, then add this new object, like this:
var YourList = YourObservableCollection.ToList();
var YourObject = new YourClass { ..... };
YourList.Add(YourObject);
YourObservableCollection.InsertInPlace(YourList.DoYourLinqOrdering().ToList(), YourObject);
But since the ObservableCollection could be in a different order than the list because of the selection in the "DoYourLinqOrdering()" (this would happen if the collection wasn't previously ordered) I've added the first extession (OrderByReference) in the insert as you can see in the begining of the answer. It will not take long if it doesn't need to move the itens arround, so I did't saw a problem in using it.
As performance goes, I've compared the methods by checking the time it takes for each to finish, so not ideal, but anyway, I've tested an observable collection with 20000 itens. For the OrderByReference I didn't saw great difference in the performance by adding the Equal object checker, but if not all itens need to be moved it is faster and it doesn't fire unecessary Move events on the collecitonChanged, so thats something. For the InsertInPlace is the same thing, if the ObservableCollection is already sorted, just checking if the objects are in the right place is faster than moving all the itens around, so there was not a huge difference in time if it is just passing through the Equals statement and you get the benefit of being sure everything is where it should be.
Be aware that if you use this extession with objects that dont mach or with a list that have more or less objects you will get an ArgumentOutOfRangeException or some other unexpect behaviour.
Hopes this helps somebody!
One should ask why you would want a public getter method for the password. Hibernate, or any other ORM framework, will do with a private getter method. For checking whether the password is correct, you can use
public boolean checkPassword(String password){
return this.password.equals(anyHashingMethod(password));
}
This borrows from a few other answers here but I thought it might help someone. If you define the following function on your custom object, then you have a factory function that you can pass a generic object into and it will return for you an instance of the class.
CustomObject.create = function (obj) {
var field = new CustomObject();
for (var prop in obj) {
if (field.hasOwnProperty(prop)) {
field[prop] = obj[prop];
}
}
return field;
}
Use like this
var typedObj = CustomObject.create(genericObj);
If you are using ES6 features and you're in an async function, you can effectively halt the code execution for a certain time with this function:
const delay = millis => new Promise((resolve, reject) => {
setTimeout(_ => resolve(), millis)
});
This is how you use it:
await delay(5000);
It will stall for the requested amount of milliseconds, but only if you're in an async function. Example below:
const myFunction = async function() {
// first code block ...
await delay(5000);
// some more code, executed 5 seconds after the first code block finishes
}
I would use:
<img src="picture.jpg?20130910043254">
where "20130910043254" is the modification time of the file.
When uploading an image, its filename is not kept in the database. It is renamed as Image.jpg (to simply things out when using it). When replacing the existing image with a new one, the name doesn't change either. Just the content of the image file changes.
I think there are two types of simple solutions: 1) those which come to mind first (straightforward solutions, because they are easy to come up with), 2) those which you end up with after thinking things over (because they are easy to use). Apparently, you won't always benefit if you chose to think things over. But the second options is rather underestimated, I believe. Just think why php
is so popular ;)
When your HTMLElement
doesn't have an id
, name
or class
to call,
then use
<input type="text" (click)="selectedInput($event)">
selectedInput(event: MouseEvent) {
log(event.srcElement) // HTMInputLElement
}
On Debian LINUX, I use: ps -o pid= -u username | xargs sudo kill -9
.
With -o pid=
the ps header is supressed, and the output is only the pid list. As far as I know, Debian shell is POSIX compliant.
Depends on what you need, you have a couple of choices, you can do:
// this will replace the first occurrence of "www." and return "testwww.com"
"www.testwww.com".replace("www.", "");
// this will slice the first four characters and return "testwww.com"
"www.testwww.com".slice(4);
// this will replace the www. only if it is at the beginning
"www.testwww.com".replace(/^(www\.)/,"");
An alternative to type -a
is command -V
Since most of the times I am interested in the first result only, I also pipe from head. This way the screen will not flood with code in case of a bash function.
command -V lshw | head -n1
with open('test.txt', 'r') as inf, open('test1.txt', 'w') as outf:
for line in inf:
line = line.strip()
if line:
try:
outf.write(str(int(line, 16)))
outf.write('\n')
except ValueError:
print("Could not parse '{0}'".format(line))
Yes it remains the same. but why not easily test it? Make an ArrayList, fill it and then retrieve the elements!
Here is a solution in plain and simple C++ code with no fancy function, use DMA to allocate a dynamic string array, and put data in array till you find a open space. please refer code below with comments. I hope it helps.
#include<bits/stdc++.h>
using namespace std;
int main()
{
string data="hello there how are you"; // a_size=5, char count =23
//getline(cin,data);
int count=0; // initialize a count to count total number of spaces in string.
int len=data.length();
for (int i = 0; i < (int)data.length(); ++i)
{
if(data[i]==' ')
{
++count;
}
}
//declare a string array +1 greater than the size
// num of space in string.
string* str = new string[count+1];
int i, start=0;
for (int index=0; index<count+1; ++index) // index array to increment index of string array and feed data.
{ string temp="";
for ( i = start; i <len; ++i)
{
if(data[i]!=' ') //increment temp stored word till you find a space.
{
temp=temp+data[i];
}else{
start=i+1; // increment i counter to next to the space
break;
}
}str[index]=temp;
}
//print data
for (int i = 0; i < count+1; ++i)
{
cout<<str[i]<<" ";
}
return 0;
}

I had the problem with multiple IDE. Closing Eclipse, killing from task manager or restarting didnt help. Just deleted the AVD and created it again.
I was using github earlier for one of my php project. While using github, I was using ssh instead of https. I had my machine set up like that and every time I used to commit and push the code, it would ask me my rsa key password.
After some days, I stopped working on the php project and forgot my rsa password. Recently, I started working on a java project and moved to bitbucket. Since, I had forgotten the password and there is no way to recover it I guess, I decided to use the https(recommended) protocol for the new project and got the same error asked in the question.
How I solved it?
Ran this command to tell my git to use https instead of ssh:
git config --global url."https://".insteadOf git://
Remove any remote if any
git remote rm origin
Redo everything from git init to git push and it works!
PS: I also un-installed ssh from my machine during the debug process thinking that, removing it will fix the problem. Yes I know!! :)
Using this simple script
if($(window.location.hash).length > 0){
$('html, body').animate({ scrollTop: $(window.location.hash).offset().top}, 1000);
}
Would make in sort that if a hash tag is found in the url, the scrollTo animate to the ID. If not hash tag found, then ignore the script.
Form.Close() is use to close an instance of a Form with in .NET application it does not kill the entire application. Application.exit() kills your application.
Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.
note I changed the varchar2(32000) to CLOB
set serveroutput ON
CREATE TABLE testclob
(
id NUMBER,
c CLOB,
d VARCHAR2(4000)
);
DECLARE
reallybigtextstring CLOB := '123';
i INT;
BEGIN
WHILE Length(reallybigtextstring) <= 60000 LOOP
reallybigtextstring := reallybigtextstring
|| '000000000000000000000000000000000';
END LOOP;
INSERT INTO testclob
(id,

You will save yourself a heap of trouble (long term) if you store a ZIP Code as a character string, which it is, rather than a number, which it is not.
I think this should work.

You can still use the Authorization header with OAuth 2.0. There is a Bearer type specified in the Authorization header for use with OAuth bearer tokens (meaning the client app simply has to present ("bear") the token). The value of the header is the access token the client received from the Authorization Server.
It's documented in this spec: https://tools.ietf.org/html/rfc6750#section-2.1
E.g.:
GET /resource HTTP/1.1

Building on Lauritz` answer, here's a version with the following changes
__call__
instead of __getitem__
from bisect import bisect_right
class Interpolate:
def __init__(self, x_list, y_list):
if any(y - x <= 0 for x, y in zip(x_list, x_list[1:])):
raise ValueError("x_list must be in strictly ascending order!")
self.x_list = x_list
self.y_list = y_list
intervals = zip(x_list, x_list[1:], y_list, y_list[1:])
self.slopes = [(y2 - y1) / (x2 - x1) for x1, x2, y1, y2 in intervals]
def __call__(self, x):
if not (self.x_list[0] <= x <= self.x_list[-1]):
raise ValueError("x out of bounds!")
if x == self.x_list[-1]:
return self.y_list[-1]
i = bisect_right(self.x_list, x) - 1
return self.y_list[i] + self.slopes[i] * (x - self.x_list[i])
Example usage:
>>> interp = Interpolate([1, 2.5, 3.4, 5.8, 6], [2, 4, 5.8, 4.3, 4])
>>> interp(4)

Disable all table constraints
ALTER TABLE TableName NOCHECK CONSTRAINT ConstraintName
-- Enable all table constraints
ALTER TABLE TableName CHECK CONSTRAINT ConstraintName
File.expand_path File.dirname(__FILE__)
will return the directory relative to the file this command is called from.
But Dir.pwd
returns the working directory (results identical to executing pwd
in your terminal)

The language used by Facebook is PHP.
Also, do any other social networking sites use the same language?
The other one I know of is friendster.
Did a quick test selecting one row from a 50,000 row table and joining with one row from a 100,000 row table. Basically looked like:
$id = mt_rand(1, 50000);
$row = $db->fetchOne("SELECT * FROM table1 WHERE id = " . $id);
$row = $db->fetchOne("SELECT * FROM table2 WHERE other_id = " . $row['other_id']);
vs
$id = mt_rand(1, 50000);
$db->fetchOne("SELECT table1.*, table2.*
FROM table1
LEFT JOIN table1.other_id = table2.other_id
WHERE table1.id = " . $id);
The two select method took 3.7 seconds for 50,000 reads whereas the JOIN took 2.0 seconds on my at-home slow computer. INNER JOIN and LEFT JOIN did not make a difference. Fetching multiple rows (e.g., using IN SET) yielded similar results.
You can also encode bytes to Base64. How to get this from a stream see here: How to convert an Stream into a byte[] in C#?
Or I think it should be also possible to use the .ToString() method and encode this.
This sometimes happen if you remove Java from your path variables. To set the PATH variable again, add the full path of the jdk\bin directory to the PATH variable. Typically, the full path is:
C:\Program Files\Java\jdk-11\bin
To set the PATH variable on Microsoft Windows:
1) Your cron is wrong. If you want to run job every 15 mins on Jenkins use this:
H/15 * * * *
2) Warning from Jenkins Spread load evenly by using ‘...’ rather than ‘...’
came with JENKINS-17311:
To allow periodically scheduled tasks to produce even load on the system, the symbol H (for “hash”) should be used wherever possible. For example, using 0 0 * * * for a dozen daily jobs will cause a large spike at midnight. In contrast, using H H * * * would still execute each job once a day, but not all at the same time, better using limited resources.
Examples:
H/15 * * * *
- every fifteen minutes (perhaps at :07, :22, :37, :52):H(0-29)/10 * * * *
- every ten minutes in the first half of every hour (three times, perhaps at :04, :14, :24)H 9-16/2 * * 1-5
- once every two hours every weekday (perhaps at 10:38 AM, 12:38 PM, 2:38 PM, 4:38 PM)H H 1,15 1-11 *
- once a day on the 1st and 15th of every month except DecemberjQuery has .mouseover()
and .html()
. You can tie the mouseover event to a function:
The same thing can be done when you get the mouseover event indicating that the cursor is no longer hanging over the div.
This will give you a list of a single group, and the members of each group.
param
(
[Parameter(Mandatory=$true,position=0)]
[String]$GroupName
)
import-module activedirectory
# optional, add a wild card..
# $groups = $groups + "*"
$Groups = Get-ADGroup -filter {Name -like $GroupName} | Select-Object Name
ForEach ($Group in $Groups)
{write-host " "
write-host "$($group.name)"
write-host "----------------------------"
Get-ADGroupMember -identity $($groupname) -recursive | Select-Object samaccountname
}
write-host "Export Complete"
If you want the friendly name, or other details, add them to the end of the select-object query.
Only thing that worked for me:
// save file
$pdf->Output(__DIR__ . '/example_001.pdf', 'F');
exit();
As "there are tens of thousands of cells in the page" binding the click-event to every single cell will cause a terrible performance problem. There's a better way to do this, that is binding a click event to the body & then finding out if the cell element was the target of the click. Like this:
$('body').click(function(e){
var Elem = e.target;
if (Elem.nodeName=='td'){
//.... your business goes here....
// remember to replace $(this) with $(Elem)
}
})
This method will not only do your task with native "td" tag but also with later appended "td". I think you'll be interested in this article about event binding & delegate
Or you can simply use the ".on()" method of jQuery with the same effect:
$('body').on('click', 'td', function(){
...
});
You have set your %JAVA_HOME
to jdk 1.7, but you are trying to compile using 1.8. Install jdk 1.8 and make sure your %JAVA_HOME
points to that or drop the target release to 1.7.
invalid target release: 1.8
The target release refers to the jdk version.
This way is the least expensive way and always keeps your image view rounded:
class RoundedImageView: UIImageView {
override init(frame: CGRect) {
super.init(frame: frame)
clipsToBounds = true
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
clipsToBounds = true
}
override func layoutSubviews() {
super.layoutSubviews()
assert(bounds.height == bounds.width, "The aspect ratio isn't 1/1. You can never round this image view!")
layer.cornerRadius = bounds.height / 2
}
}
The other answers are telling you to make views rounded based on frame calculations set in a UIViewController
s viewDidLoad()
method. This isn't correct, since it isn't sure what the final frame will be.
My sample, Tested in Android studio 2.1
Define button in xml layout
<Button
android:id="@+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
Java pulsation detect
Button clickButton = (Button) findViewById(R.id.btn1);
if (clickButton != null) {
clickButton.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v) {
/***Do what you want with the click here***/
}
});
}
Here is a check list for you:
1) Is your app published? (Production APK is not required for publishing)
2) Did your alpha/beta testers "Accept invitation" to Google+ community or Google group?
3) Are your alpha/beta testers logged in their Google+ account?
4) Are your alpha/beta testers using your link from Google Play developer console? It has format like this: https://play.google.com/apps/testing/com.yourdomain.package
Here is a simple one
this.$children[indexOfComponent].childsMethodName();
Pandas has the itertuples
method to do exactly this:
list(df[['lat', 'long']].itertuples(index=False, name=None))
In addition to the good answers above, PHP also has a built-in filter function that is quite useful: filter-var.
To remove HMTL characters, use:
$cleanString = filter_var($dirtyString, FILTER_SANITIZE_STRING);

The approach I would take is: when reading the chapters from the database, instead of a collection of chapters, use a collection of books. This will have your chapters organised into books and you'll be able to use information from both classes to present the information to the user (you can even present it in a hierarchical way easily when using this approach).
import java.io.*;
public class Code {
public static void main(String[] args) throws Exception {
ProcessBuilder builder = new ProcessBuilder("ls", "-ltr");
Process process = builder.start();
StringBuilder out = new StringBuilder();
try (BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()))) {
String line = null;
while ((line = reader.readLine()) != null) {
out.append(line);
out.append("\n");
}
System.out.println(out);
}
}
}
Having that:
public interface ITerm
{
string Name { get; }
}
public class Value : ITerm...
public class Variable : ITerm...
public class Query
{
public IList<ITerm> Terms { get; }
...
}
I managed conversion trick implementing that:
public class TermConverter : JsonConverter
{
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
var field = value.GetType().Name;
writer.WriteStartObject();
writer.WritePropertyName(field);
writer.WriteValue((value as ITerm)?.Name);
writer.WriteEndObject();
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue,
JsonSerializer serializer)
{
var jsonObject = JObject.Load(reader);
var properties = jsonObject.Properties().ToList();
var value = (string) properties[0].Value;
return properties[0].Name.Equals("Value") ? (ITerm) new Value(value) : new Variable(value);
}
public override bool CanConvert(Type objectType)
{
return typeof (ITerm) == objectType || typeof (Value) == objectType || typeof (Variable) == objectType;
}
}
It allows me to serialize and deserialize in JSON like:
string JsonQuery = "{\"Terms\":[{\"Value\":\"This is \"},{\"Variable\":\"X\"},{\"Value\":\"!\"}]}";
...
var query = new Query(new Value("This is "), new Variable("X"), new Value("!"));
var serializeObject = JsonConvert.SerializeObject(query, new TermConverter());
Assert.AreEqual(JsonQuery, serializeObject);
...
var queryDeserialized = JsonConvert.DeserializeObject<Query>(JsonQuery, new TermConverter());
yan.kun was on the right track but this is much much easier.
public FileContentResult DownloadCSV()
{
string csv = "Charlie, Chaplin, Chuckles";
return File(new System.Text.UTF8Encoding().GetBytes(csv), "text/csv", "Report123.csv");
}
try
states.split()
it returns the list
['Alaska',
'Alabama',
'Arkansas',
'American',
'Samoa',
'Arizona',
'California',
'Colorado']
and this returns the random element of the list
import random
random.choice(states.split())
split statement parses the string and returns the list, by default it's divided into the list by spaces, if you specify the string it's divided by this string, so for example
states.split('Ari')
returns
['Alaska Alabama Arkansas American Samoa ', 'zona California Colorado']
Btw, list is in python interpretated with [] brackets instead of {} brackets, {} brackets are used for dictionaries, you can read more on this here
I see you are probably new to python, so I'd give you some advice how to use python's great documentation
Almost everything you need can be found here You can use also python included documentation, open python console and write help() If you don't know what to do with some object, I'd install ipython, write statement and press Tab, great tool which helps you with interacting with the language
I just wrote this here to show that python is great tool also because it's great documentation and it's really powerful to know this
example of textarea for disable the resize option

take look at this sample code from my project
public static IList<Letter> GetDepartmentLettersLinq(int departmentId)
{
IEnumerable<Letter> allDepartmentLetters =
from allLetter in LetterService.GetAllLetters()
join allUser in UserService.GetAllUsers() on allLetter.EmployeeID equals allUser.ID into usersGroup
from user in usersGroup.DefaultIfEmpty()// here is the tricky part
join allDepartment in DepartmentService.GetAllDepartments() on user.DepartmentID equals allDepartment.ID
where allDepartment.ID == departmentId
select allLetter;
return allDepartmentLetters.ToArray();
}
in this code I joined 3 tables and I spited join condition from where clause
note: the Services classes are just warped(encapsulate) the database operations
To answer your question, no. That would be possible with div though. THe only question is would cause a hazzle if the functionality were done with div rather than tables.
You could use iterator to do that:
For keys:
for (Iterator <tab> itr= hash.keySet().iterator(); itr.hasNext();) {
// use itr.next() to get the key value
}
You can use iterator similarly with values.
use following it handles all cases:-
import re
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '2.3')
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '2.')
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '.3')
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '2.3sd')
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '2.3')
Issue these on the command line:
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
After you do this, make sure your directory is like this:
drwx------ 2 lab lab 4.0K Mar 13 08:33 .
drwx------ 8 lab lab 4.0K Mar 13 08:07 ..
-rw------- 1 lab lab 436 Mar 13 08:33 authorized_keys
-rw------- 1 lab lab 1.7K Mar 13 07:35 id_rsa
-rw-r--r-- 1 lab lab 413 Mar 13 07:35 id_rsa.pub
You should also check you JSON (not in DevTools, but on a backend). Angular HttpClient having a hard time parsing JSON with \0
characters and DevTools will ignore then, so it's quite hard to spot in Chrome.
Based on this article
At of all the solution i have tried no one work as expected, i study heroku by default the .env File should maintain the convention PORT, the process.env.PORT, heroku by default will look for the Keyword PORT.
Cancel any renaming such as APP_PORT= instead use PORT= in your env file.
You can't run cd
this way, because cd
isn't a real program; it's a built-in part of the command-line, and all it does is change the command-line's environment. It doesn't make sense to run it in a subprocess, because then you're changing that subprocess's environment — but that subprocess closes immediately, discarding its environment.
To set the current working directory in your actual Java program, you should write:
System.setProperty("user.dir", "C:\\Program Files\\Flowella");
go to your styles and put the parent
parent="Theme.AppCompat"
instead of
parent="@android:style/Theme.Holo.Light"
A practical observation... In my NodeJS script I have the following function:
function writeToLogFile (message) {
fs.appendFile('myserverlog.txt', Date() + " " + message + "\r\n", function (err) {
if (err) throw err;
});
}
First I had only "\n" but I noticed that when I open the log file in Notepad, it shows all entries on the same line. Notepad++ on the other hand shows the entries each on their own line. After changing the code to "\r\n", even Notepad shows every entry on its own line.
You were almost done without any changes besides how you spyOn
.
When you use the spy, you have two options: spyOn
the App.prototype
, or component component.instance()
.
const spy = jest.spyOn(Class.prototype, "method")
The order of attaching the spy on the class prototype and rendering (shallow rendering) your instance is important.
const spy = jest.spyOn(App.prototype, "myClickFn");
const instance = shallow(<App />);
The App.prototype
bit on the first line there are what you needed to make things work. A JavaScript class
doesn't have any of its methods until you instantiate it with new MyClass()
, or you dip into the MyClass.prototype
. For your particular question, you just needed to spy on the App.prototype
method myClickFn
.
jest.spyOn(component.instance(), "method")
const component = shallow(<App />);
const spy = jest.spyOn(component.instance(), "myClickFn");
This method requires a shallow/render/mount
instance of a React.Component
to be available. Essentially spyOn
is just looking for something to hijack and shove into a jest.fn()
. It could be:
A plain object
:
const obj = {a: x => (true)};
const spy = jest.spyOn(obj, "a");
A class
:
class Foo {
bar() {}
}
const nope = jest.spyOn(Foo, "bar");
// THROWS ERROR. Foo has no "bar" method.
// Only an instance of Foo has "bar".
const fooSpy = jest.spyOn(Foo.prototype, "bar");
// Any call to "bar" will trigger this spy; prototype or instance
const fooInstance = new Foo();
const fooInstanceSpy = jest.spyOn(fooInstance, "bar");
// Any call fooInstance makes to "bar" will trigger this spy.
Or a React.Component instance
:
const component = shallow(<App />);
/*
component.instance()
-> {myClickFn: f(), render: f(), ...etc}
*/
const spy = jest.spyOn(component.instance(), "myClickFn");
Or a React.Component.prototype
:
/*
App.prototype
-> {myClickFn: f(), render: f(), ...etc}
*/
const spy = jest.spyOn(App.prototype, "myClickFn");
// Any call to "myClickFn" from any instance of App will trigger this spy.
I've used and seen both methods. When I have a beforeEach()
or beforeAll()
block, I might go with the first approach. If I just need a quick spy, I'll use the second. Just mind the order of attaching the spy.
EDIT:
If you want to check the side effects of your myClickFn
you can just invoke it in a separate test.
const app = shallow(<App />);
app.instance().myClickFn()
/*
Now assert your function does what it is supposed to do...
eg.
expect(app.state("foo")).toEqual("bar");
*/
EDIT:
Here is an example of using a functional component. Keep in mind that any methods scoped within your functional component are not available for spying. You would be spying on function props passed into your functional component and testing the invocation of those. This example explores the use of jest.fn()
as opposed to jest.spyOn
, both of which share the mock function API. While it does not answer the original question, it still provides insight on other techniques that could suit cases indirectly related to the question.
function Component({ myClickFn, items }) {
const handleClick = (id) => {
return () => myClickFn(id);
};
return (<>
{items.map(({id, name}) => (
<div key={id} onClick={handleClick(id)}>{name}</div>
))}
</>);
}
const props = { myClickFn: jest.fn(), items: [/*...{id, name}*/] };
const component = render(<Component {...props} />);
// Do stuff to fire a click event
expect(props.myClickFn).toHaveBeenCalledWith(/*whatever*/);
You can also solve this by setting an endpoint which waits for the service to be up by using netcat (using the docker-wait script). I like this approach as you still have a clean command
section in your docker-compose.yml
and you don't need to add docker specific code to your application:
version: '2'
services:
db:
image: postgres
django:
build: .
command: python manage.py runserver 0.0.0.0:8000
entrypoint: ./docker-entrypoint.sh db 5432
volumes:
- .:/code
ports:
- "8000:8000"
depends_on:
- db
Then your docker-entrypoint.sh
:
#!/bin/sh
postgres_host=$1
postgres_port=$2
shift 2
cmd="$@"
# wait for the postgres docker to be running
while ! nc $postgres_host $postgres_port; do
>&2 echo "Postgres is unavailable - sleeping"
sleep 1
done
>&2 echo "Postgres is up - executing command"
# run the command
exec $cmd
This is nowadays documented in the official docker documentation.
PS: You should install netcat
in your docker instance if this is not available. To do so add this to your Docker
file :
RUN apt-get update && apt-get install netcat-openbsd -y
"By the way...... How to refresh it every time so it print mi in one place just change the number."
It's really tricky topic. What zack suggested ( outputting console control codes ) is one way to achieve that.
You can use (n)curses, but that works mainly on *nixes.
On Windows (and here goes interesting part) which is rarely mentioned (I can't understand why) you can use Python bindings to WinAPI (http://sourceforge.net/projects/pywin32/ also with ActivePython by default) - it's not that hard and works well. Here's a small example:
import win32console, time
output_handle = win32console.GetStdHandle( win32console.STD_OUTPUT_HANDLE )
info = output_handle.GetConsoleScreenBufferInfo()
pos = info["CursorPosition"]
for i in "\\|/-\\|/-":
output_handle.WriteConsoleOutputCharacter( i, pos )
time.sleep( 1 )
Or, if you want to use print
(statement or function, no difference):
import win32console, time
output_handle = win32console.GetStdHandle( win32console.STD_OUTPUT_HANDLE )
info = output_handle.GetConsoleScreenBufferInfo()
pos = info["CursorPosition"]
for i in "\\|/-\\|/-":
print i
output_handle.SetConsoleCursorPosition( pos )
time.sleep( 1 )
win32console
module enables you to do many more interesting things with windows console... I'm not a big fan of WinAPI, but recently I realized that at least half of my antipathy towards it was caused by writing WinAPI code in C - pythonic bindings are much easier to use.
All other answers are great and pythonic, of course, but... What if I wanted to print on previous line? Or write multiline text, than clear it and write the same lines again? My solution makes that possible.
Git keeps all of its files in the .git directory. Just remove that one and init again.
This post well show you how to find the hide .git file on Windows, Mac OSX, Ubuntu
If the component is an EJB, then, there shouldn't be a problem injecting an EM.
But....In JBoss 5, the JAX-RS integration isn't great. If you have an EJB, you cannot use scanning and you must manually list in the context-param resteasy.jndi.resource. If you still have scanning on, Resteasy will scan for the resource class and register it as a vanilla JAX-RS service and handle the lifecycle.
This is probably the problem.
Here is my solution:
SELECT
DISTINCT NAME,
MAX(MESSAGES) OVER(PARTITION BY NAME) MESSAGES
FROM MESSAGE;
You can use indexOf(). Like:
var Color = ["blue", "black", "brown", "gold"];
var a = Color.indexOf("brown");
alert(a);
The indexOf() method searches the array for the specified item, and returns its position. And return -1 if the item is not found.
If you want to search from end to start, use the lastIndexOf() method:
var Color = ["blue", "black", "brown", "gold"];
var a = Color.lastIndexOf("brown");
alert(a);
The search will start at the specified position, or at the end if no start position is specified, and end the search at the beginning of the array.
Returns -1 if the item is not found.
You need a whole input match here.
System.out.println(test.matches("^(http|https|ftp)://.*$"));
Edit:(Based on @davidchambers's comment)
System.out.println(test.matches("^(https?|ftp)://.*$"));
If you are not using GCE or EKS (you used kubeadm
) you can add an externalIPs
spec to your service YAML. You can use the IP associated with your node's primary interface such as eth0
. You can then access the service externally, using the external IP of the node.
...
spec:
type: LoadBalancer
externalIPs:
- 192.168.0.10
Use Class instead of Interface that is what I discovered after all my research.
Why? A class alone is less code than a class-plus-interface. (anyway you may require a Class for data model)
Why? A class can act as an interface (use implements instead of extends).
Why? An interface-class can be a provider lookup token in Angular dependency injection.
Basically a Class can do all, what an Interface will do. So may never need to use an Interface.
Similar to the other examples, but using html sizing, I use:
<img src="image1.png" width="425"/> <img src="image2.png" width="425"/>
Here is an example
<img src="https://openclipart.org/image/2400px/svg_to_png/28580/kablam-Number-Animals-1.png" width="200"/> <img src="https://openclipart.org/download/71101/two.svg" width="300"/>
I tested this using Remarkable.
simple synchronous way with node:
let fs = require('fs')
let filename = "your-file.something"
let content = fs.readFileSync(process.cwd() + "/" + filename).toString()
console.log(content)
Simply casting the string as an int
won't work reliably. You need to convert it to an int32
. For this you can use the .NET convert
class and its ToInt32
method. The method requires a string
($strNum
) as the main input, and the base number
(10
) for the number system to convert to. This is because you can not only convert to the decimal system (the 10
base number), but also to, for example, the binary system (base 2).
Give this method a try:
[string]$strNum = "1.500"
[int]$intNum = [convert]::ToInt32($strNum, 10)
$intNum
This is late but this may help someone :) :) For adding the view programmatically try like
LinearLayout rlmain = new LinearLayout(this);
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.FILL_PARENT);
LinearLayout ll1 = new LinearLayout (this);
ImageView iv = new ImageView(this);
iv.setImageResource(R.drawable.logo);
LinearLayout .LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
iv.setLayoutParams(lp);
ll1.addView(iv);
rlmain.addView(ll1);
setContentView(rlmain, llp);
This will create your entire view programmatcally. You can add any number of view as same. Hope this may help. :)
JUnit 5 (Jupiter) provides three functions to check exception absence/presence:
assertAll?()
Asserts that all supplied executables
do not throw exceptions.
assertDoesNotThrow?()
Asserts that execution of the
supplied executable
/supplier
does not throw any kind of exception.
This function is available
since JUnit 5.2.0 (29 April 2018).
assertThrows?()
Asserts that execution of the supplied executable
throws an exception of the expectedType
and returns the exception.

In spite of how old this question is and similar to this answer by technosaurus. I had a hard time finding a solution that was portable across most platforms (That I Use) as well as older versions of bash. I have also been frustrated with arrays, functions and use of prints, echos and temporary files to retrieve trivial variables. This works very well for me so far I thought I would share. My main testing environments are:
- GNU bash, version 4.1.2(1)-release (x86_64-redhat-linux-gnu)
- GNU bash, version 3.2.57(1)-release (sparc-sun-solaris2.10)
lcs="abcdefghijklmnopqrstuvwxyz"
ucs="ABCDEFGHIJKLMNOPQRSTUVWXYZ"
input="Change Me To All Capitals"
for (( i=0; i<"${#input}"; i++ )) ; do :
for (( j=0; j<"${#lcs}"; j++ )) ; do :
if [[ "${input:$i:1}" == "${lcs:$j:1}" ]] ; then
input="${input/${input:$i:1}/${ucs:$j:1}}"
fi
done

Simple C-style for loop to iterate through the strings. For the line below if you have not seen anything like this before this is where I learned this. In this case the line checks if the char ${input:$i:1} (lower case) exists in input and if so replaces it with the given char ${ucs:$j:1} (upper case) and stores it back into input.
input="${input/${input:$i:1}/${ucs:$j:1}}"
If you run your legacy program with ProcessBuilder, you will be able to specify its working directory.
Yep, just add parenthesis (calling the function). Make sure the function is in scope and actually returns something.
<ul class="ui-listview ui-radiobutton" ng-repeat="meter in meters">
<li class = "ui-divider">
{{ meter.DESCRIPTION }}
{{ htmlgeneration() }}
</li>
</ul>
An "if" is not a loop. Just use the break inside the "if" and it will break out of the "while".
If you ever need to use genuine nested loops, Java has the concept of a labeled break. You can put a label before a loop, and then use the name of the label is the argument to break. It will break outside of the labeled loop.

QUEUE:
In my case, the problem was caused by some Response.Write commands at Master Page of the website (code behind). They were there only for debugging purposes (that's not the best way, I know)...
You have to add a manifest to the jar, which tells the java runtime what the main class is. Create a file 'Manifest.mf' with the following content:
Manifest-Version: 1.0
Main-Class: your.programs.MainClass
Change 'your.programs.MainClass' to your actual main class. Now put the file into the Jar-file, in a subfolder named 'META-INF'. You can use any ZIP-utility for that.
To make the change for one session, use this command:
:set tabstop=4
To make the change permanent, add it to ~/.vimrc
or ~/.vim/vimrc
:
set tabstop=4
This will affect all files, not just css. To only affect css files:
autocmd Filetype css setlocal tabstop=4
as stated in Michal's answer.
This also one way of doing it and its works. Please check the following url https://jsfiddle.net/sarfarazk/ofgqm0sh/
