Following is small snippet i've created in javascript to convert array of objects to hash map, indexed by attribute value of object. You can provide a function to evaluate the key of hash map dynamically (run time).
function isFunction(func){
return Object.prototype.toString.call(func) === '[object Function]';
}
/**
* This function converts an array to hash map
* @param {String | function} key describes the key to be evaluated in each object to use as key for hasmap
* @returns Object
* @Example
* [{id:123, name:'naveen'}, {id:345, name:"kumar"}].toHashMap("id")
Returns :- Object {123: Object, 345: Object}
[{id:123, name:'naveen'}, {id:345, name:"kumar"}].toHashMap(function(obj){return obj.id+1})
Returns :- Object {124: Object, 346: Object}
*/
Array.prototype.toHashMap = function(key){
var _hashMap = {}, getKey = isFunction(key)?key: function(_obj){return _obj[key];};
this.forEach(function (obj){
_hashMap[getKey(obj)] = obj;
});
return _hashMap;
};

I tried more or less all of the other solutions the other day, but none of them worked for me until I tried this one:
var submitButton = document.getElementById('submitButton');
submitButton.setAttribute('onclick', 'alert("hello");');
As far as I can tell, it works perfectly.
This single line would do that:
$array = array_column($array, 'plan');
The first argument is an array | The second argument is an array key.

The org.apache.commons.lang.StringEscapeUtils.unescapeJava()

and everything that uses it, including \a

. charAt
interface instead of the codePoint
interface, thus promulgating the delusion that a Java char
is guaranteed to hold a Unicode character. It’s not. They only get away with this because no UTF-16 surrogate will wind up looking for anything they’re looking for. I wrote a string unescaper which solves the OP’s question without all the irritations of the Apache code.

* It's completely ridiculous that there's no standard
* unescape_java_string function. Since I have to do the
* damn thing myself, I might as well make it halfway useful
* by supporting things Java was too stupid to consider in
* strings:
*
* => "?" items are additions to Java string escapes
* but normal in Java regexes
*
* => "!" items are also additions to Java regex escapes
*
* Standard singletons: ?\a ?\e \f \n \r \t
*
* NB: \b is unsupported as backspace so it can pass-through
* to the regex translator untouched; I refuse to make anyone
* doublebackslash it as doublebackslashing is a Java idiocy
* I desperately wish would die out. There are plenty of
* other ways to write it:
*
* \cH, \12, \012, \x08 \x{8}, \u0008, \U00000008
*
* Octal escapes: \0 \0N \0NN \N \NN \NNN
* Can range up to !\777 not \377
*
* TODO: add !\o{NNNNN}
* last Unicode is 4177777
* maxint is 37777777777
*
* Control chars: ?\cX
* Means: ord(X) ^ ord('@')
*
* Old hex escapes: \xXX
* unbraced must be 2 xdigits
*
* Perl hex escapes: !\x{XXX} braced may be 1-8 xdigits
* NB: proper Unicode never needs more than 6, as highest
* valid codepoint is 0x10FFFF, not maxint 0xFFFFFFFF
*
* Lame Java escape: \[IDIOT JAVA PREPROCESSOR]uXXXX must be
* exactly 4 xdigits;
*
* I can't write XXXX in this comment where it belongs
* because the damned Java Preprocessor can't mind its
* own business. Idiots!
*
* Lame Python escape: !\UXXXXXXXX must be exactly 8 xdigits
*
* TODO: Perl translation escapes: \Q \U \L \E \[IDIOT JAVA PREPROCESSOR]u \l
* These are not so important to cover if you're passing the

If it helps others, you’re welcome to it — no strings attached. If you improve it, I’d love for you to mail me your enhancements, but you certainly don’t have to.
Just add 20 minutes in milliseconds to your date:
var currentDate = new Date();
currentDate.setTime(currentDate.getTime() + 20*60*1000);
It's possible with a lot of work.
Basically, you have to post likes action via the Open Graph API. Then, you can add a custom design to your like button.
But then, you''ll need to keep track yourself of the likes so a returning user will be able to unlike content he liked previously.
Plus, you'll need to ask user to log into your app and ask them the publish_action
permission.
All in all, if you're doing this for an application, it may worth it. For a website where you basically want user to like articles, then this is really to much.
Also, consider that you increase your drop-off rate each time you ask user a permission via a Facebook login.
If you want to see an example, I've recently made an app using the open graph like button, just hover on some photos in the mosaique to see it
First, change your inner code for another loop (for
and while
) so you can repeat the same code for different values.
More specific for your problem, if you want to know if a given n
is prime, you need to divide it for all values between 2 and sqrt(n). If any of the modules is 0, it is not prime.
If you want to find all primes, you can speed it and check n
only by dividing by the previously found primes. Another way of speeding the process is the fact that, apart from 2 and 3, all the primes are 6*k
plus or less 1.
To run Mongo DB demon with mongod
command, you should have a database directory, probably you need to run:
mkdir C:\data\db
Also, MongoDB need to have a write permissions for that directory or it should be run with superuser permissions, like sudo mongod
.
I solved this issue by doing this:
instead of
<Route path="/" component={HomePage} />
do this
<Route
path="/" component={props => <HomePage {...props} />} />
While its not bad practice to use break and there are many excellent uses for it, it should not be all you rely upon. Almost any use of a break can be written into the loop condition. Code is far more readable when real conditions are used, but in the case of a long-running or infinite loop, breaks make perfect sense. They also make sense when searching for data, as shown above.
You can convert a datetime.date object into a pandas Timestamp like this:
#!/usr/bin/env python3
# coding: utf-8
import pandas as pd
import datetime
# create a datetime data object
d_time = datetime.date(2010, 11, 12)
# create a pandas Timestamp object
t_stamp = pd.to_datetime('2010/11/12')
# cast `datetime_timestamp` as Timestamp object and compare
d_time2t_stamp = pd.to_datetime(d_time)
# print to double check
print(d_time)
print(t_stamp)
print(d_time2t_stamp)
# since the conversion succeds this prints `True`
print(d_time2t_stamp == t_stamp)
I think this will help you
function calculate_time_span($date){
$seconds = strtotime(date('Y-m-d H:i:s')) - strtotime($date);
$months = floor($seconds / (3600*24*30));
$day = floor($seconds / (3600*24));
$hours = floor($seconds / 3600);
$mins = floor(($seconds - ($hours*3600)) / 60);
$secs = floor($seconds % 60);
if($seconds < 60)
$time = $secs." seconds ago";
else if($seconds < 60*60 )
$time = $mins." min ago";
else if($seconds < 24*60*60)
$time = $hours." hours ago";
else if($seconds < 24*60*60)
$time = $day." day ago";
else
$time = $months." month ago";
return $time;
}
This solution does not address obvious date validations such as making sure date parts are integers or that date parts comply with obvious validation checks such as the day being greater than 0 and less than 32. This solution assumes that you already have all three date parts (year, month, day) and that each already passes obvious validations. Given these assumptions this method should work for simply checking if the date exists.
For example February 29, 2009 is not a real date but February 29, 2008 is. When you create a new Date object such as February 29, 2009 look what happens (Remember that months start at zero in JavaScript):
console.log(new Date(2009, 1, 29));
The above line outputs: Sun Mar 01 2009 00:00:00 GMT-0800 (PST)
Notice how the date simply gets rolled to the first day of the next month. Assuming you have the other, obvious validations in place, this information can be used to determine if a date is real with the following function (This function allows for non-zero based months for a more convenient input):
var isActualDate = function (month, day, year) {
var tempDate = new Date(year, --month, day);
return month === tempDate.getMonth();
};
This isn't a complete solution and doesn't take i18n into account but it could be made more robust.
Include:
using System.Text.Json;
Then serialize your object_to_serialize like this: JsonSerializer.Serialize(object_to_serialize)
I had similar error: "Expecting value: line 1 column 1 (char 0)"
It helped for me to add "myfile.seek(0)", move the pointer to the 0 character
with open(storage_path, 'r') as myfile:
if len(myfile.readlines()) != 0:
myfile.seek(0)
Bank_0 = json.load(myfile)
In controller:
function innerItem($scope, $element){
var jQueryInnerItem = $($element);
}
The referenced field must be a "Key" in the referenced table, not necessarily a primary key. So the "car_id" should either be a primary key or be defined with NOT NULL and UNIQUE constraints in the "Cars" table.
And moreover, both fields must be of the same type and collation.
Generally you compile most .c files in the following way:
gcc foo.c -o foo. It might vary depending on what #includes you used or if you have any external .h files. Generally, when you have a C file, it looks somewhat like the following:
#include <stdio.h>
/* any other includes, prototypes, struct delcarations... */
int main(){
*/ code */
}
When I get an 'undefined reference to main', it usually means that I have a .c file that does not have int main()
in the file. If you first learned java, this is an understandable manner of confusion since in Java, your code usually looks like the following:
//any import statements you have
public class Foo{
int main(){}
}
I would advise looking to see if you have int main()
at the top.
Since Array(3)
will create an un-iterable array, it must be populated to allow the usage of the map
Array method. A way to "convert"
is to destruct it inside Array-brackets, which "forces" the Array to be filled with undefined
values, same as Array(N).fill(undefined)
<table>
{ [...Array(3)].map((_, index) => <tr key={index}/>) }
</table>
fill()
:<table>
{ Array(3).fill(<tr/>) }
</table>
?? Problem with above example is the lack of
key
prop, which is a must.
(Using an iterator'sindex
askey
is not recommended)
const tableSize = [3,4]
const Table = (
<table>
<tbody>
{ [...Array(tableSize[0])].map((tr, trIdx) =>
<tr key={trIdx}>
{ [...Array(tableSize[1])].map((a, tdIdx, arr) =>
<td key={trIdx + tdIdx}>
{arr.length * trIdx + tdIdx + 1}
</td>
)}
</tr>
)}
</tbody>
</table>
);
ReactDOM.render(Table, document.querySelector('main'))

You must have added new files in your commits which has not been pushed. Check the file and push that file again and the try pull / push it will work. This worked for me..
There's a really great library out there you can use for this (you can actually use this in place of UISwitch
): https://github.com/Boris-Em/BEMCheckBox
Setup is easy:
BEMCheckBox *myCheckBox = [[BEMCheckBox alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
[self.view addSubview:myCheckBox];
It provides for circle and square type checkboxes
And it also does animations:
If you want to add a default value for the already created column, this works for me:
ALTER TABLE Persons
ALTER credit SET DEFAULT 0.0;
IMHO
the pervasive, implicit localization in Java is its single largest design flaw. It may be intended for user interfaces, but frankly, who really uses Java for user interfaces today except for some IDEs where you can basically ignore localization because programmers aren't exactly the target audience for it. You can fix it (especially on Linux servers) by:
LC_ALL=C TZ=UTC
To the Java Community Process members I recommend:
UTF-8/UTC
as the FIXED default instead because that's simply the default today. There is no reason to do something else, except if you want to produce threads like this.I mean, come on, aren't global static variables an anti-OO pattern? Nothing else is those pervasive defaults given by some rudimentary environment variables.......
Can use either json or ast python modules:
Using json :
=============
import json
jsonStr = '{"one" : "1", "two" : "2", "three" : "3"}'
json_data = json.loads(jsonStr)
print(f"json_data: {json_data}")
print(f"json_data['two']: {json_data['two']}")
Output:
json_data: {'one': '1', 'two': '2', 'three': '3'}
json_data['two']: 2
Using ast:
==========
import ast
jsonStr = '{"one" : "1", "two" : "2", "three" : "3"}'
json_dict = ast.literal_eval(jsonStr)
print(f"json_dict: {json_dict}")
print(f"json_dict['two']: {json_dict['two']}")
Output:
json_dict: {'one': '1', 'two': '2', 'three': '3'}
json_dict['two']: 2
the diff
method returns the difference in milliseconds. Instantiating moment(diff)
isn't meaningful.
You can define a variable :
var dayInMilliseconds = 1000 * 60 * 60 * 24;
and then use it like so :
diff / dayInMilliseconds // --> 15
Edit
actually, this is built into the diff
method, dubes' answer is better
The Ruby Style Guide says it better than I could:
Use &&/|| for boolean expressions, and/or for control flow. (Rule of thumb: If you have to use outer parentheses, you are using the wrong operators.)
# boolean expression
if some_condition && some_other_condition
do_something
end
# control flow
document.saved? or document.save!
This is the solution I came up with if anyone is interested.
https://kellyschronicles.wordpress.com/2017/12/16/dynamic-predicate-for-a-linq-query/
First we identify the single element type we need to use ( Of TRow As DataRow) and then identify the “source” we are using and tie the identifier to that source ((source As TypedTableBase(Of TRow)). Then we must specify the predicate, or the WHERE clause that is going to be passed (predicate As Func(Of TRow, Boolean)) which will either be returned as true or false. Then we identify how we want the returned information ordered (OrderByField As String). Our function will then return a EnumerableRowCollection(Of TRow), our collection of datarows that have met the conditions of our predicate(EnumerableRowCollection(Of TRow)). This is a basic example. Of course you must make sure your order field doesn’t contain nulls, or have handled that situation properly and make sure your column names (if you are using a strongly typed datasource never mind this, it will rename the columns for you) are standard.
For Python 3.x, use input()

Relative values like: height:100% will use the parent element in HTML like a reference, to use relative values in height you will need to make your html and body tags had 100% height like that:

html, body
{
height: 100%;
}

This will center a fixed div within a div while allowing the div to react with the browser. i.e. The div will be centered if there's enough space, but will collide with the edge of the browser if there isn't; similar to how a regular centered div reacts.
If you wish to customize your legend, just use the add_legend
method. It takes the same parameters as matplotlib plt.legend
.
import seaborn as sns
sns.set(style="whitegrid")
titanic = sns.load_dataset("titanic")
g = sns.factorplot("class", "survived", "sex",
data=titanic, kind="bar",
size=6, palette="muted",
legend_out=False)
g.despine(left=True)
g.set_ylabels("survival probability")
g.add_legend(bbox_to_anchor=(1.05, 0), loc=2, borderaxespad=0.)
There is a way. $q.all(...

I wrote a little post to help out with this, you can read more here https://timber.io/snippets/asynchronously-load-a-script-in-the-browser-with-javascript/, but I've attached the helper class below. It will automatically wait for a script to load and return a specified window attribute once it does.
export default class ScriptLoader {
constructor (options) {
const { src, global, protocol = document.location.protocol } = options
this.src = src
this.global = global
this.protocol = protocol
this.isLoaded = false
}
loadScript () {
return new Promise((resolve, reject) => {
// Create script element and set attributes
const script = document.createElement('script')
script.type = 'text/javascript'
script.async = true
script.src = `${this.protocol}//${this.src}`
// Append the script to the DOM
const el = document.getElementsByTagName('script')[0]
el.parentNode.insertBefore(script, el)
// Resolve the promise once the script is loaded
script.addEventListener('load', () => {
this.isLoaded = true
resolve(script)
})
// Catch any errors while loading the script
script.addEventListener('error', () => {
reject(new Error(`${this.src} failed to load.`))
})
})
}
load () {
return new Promise(async (resolve, reject) => {
if (!this.isLoaded) {
try {
await this.loadScript()
resolve(window[this.global])
} catch (e) {
reject(e)
}
} else {
resolve(window[this.global])
}
})
}
}
Usage is like this:
const loader = new Loader({
src: 'cdn.segment.com/analytics.js',
global: 'Segment',
})
// scriptToLoad will now be a reference to `window.Segment`
const scriptToLoad = await loader.load()
I made this in my code to do that
note: I am a beginner.
It is my jsp code.
<%
java.sql.Connection Conn = DBconnector.SetDBConnection(); /* make connector as you make in your code */
Statement st = null;
ResultSet rs = null;
st = Conn.createStatement();
rs = st.executeQuery("select * from department"); %>

If you're getting this bug with Xcode Beta, it's a beta bug and can be ignored (as far as I've been told). If you can build and run on a release build of Xcode without this error, then it is not your app that has the problem.
Not 100% on this, but see if this fixes the problem:
iOS Simulator -> Hardware -> Keyboard -> Toggle Software Keyboard.
Then, everything works
Just a note, since I just spent some time trouble-shooting a botched upgrade on a server.
Turned out, that (years ago) I had implemented a test to see if dynamically added interfaces (e.g. eth0:1) were present, and if so, I would bind certain proggis to the 'main' IP on eth0. Basically it was a variation on the 'ifconfig|grep...|sed... ' solution (plus checking for 'eth0:' presence).
The upgrade brought new net-tools, and with it the output has changed slightly:
old ifconfig:
eth0 Link encap:Ethernet HWaddr 42:01:0A:F0:B0:1D
inet addr:10.240.176.29 Bcast:10.240.176.29 Mask:255.255.255.255
UP BROADCAST RUNNING MULTICAST MTU:1460 Metric:1
...<SNIP>
whereas the new version will display this:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1460
inet 10.240.212.165 netmask 255.255.255.255 broadcast 10.240.212.165
...<SNIP>
rendering the hunt for 'eth0:' as well as 'inet addr:' search busted (never mind interfaces called 'em0','br0' or 'wlan0'...). Sure you could check for 'inet ' (or 'inet6'), and make the addr: part optional, but looking closer, you'll see that more or less everything has changed, 'Mask' is now 'netmask',...
The 'ip route ...' suggestion's pretty nifty - so maybe:
_MyIP="$( ip route get 8.8.8.8 | awk 'NR==1 {print $NF}' )"
if [ "A$_MyIP" == "A" ]
then
_MyIPs="$( hostname -I )"
for _MyIP in "$_MyIPs"
do
echo "Found IP: \"$_MyIP\""
done
else
echo "Found IP: $_MyIP"
fi
Well, something of that sort anyway. Since all proposed solutions seem to have circumstances where they fail, check for possible edge cases - no eth, multiple eth's & lo's, when would 'hostname -i' fail,... and then decide on best solution, check it worked, otherwise 2nd best.
Cheers 'n' beers!

It allocates space on the heap equal to an integer array of size N, and returns a pointer to it, which is assigned to int* type pointer called "array"
You need MouseClick
instead of Click
event handler, reference.
switch (e.Button) {
case MouseButtons.Left:
// Left click
break;
case MouseButtons.Right:
// Right click
break;
...
}
Another simple way:
Dir.mkdir('tmp/excel') unless Dir.exist?('tmp/excel')
From the fine manual:
ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;
There's no need to specify the type when you're just changing the nullability.
Personally i think you should learn the hard way first. It will make you a better programmer and you will be able to solve that one of a kind issue when it comes up. After you can do it with pure JavaScript then using jQuery to speed up development is just an added bonus.
If you can do it the hard way then you can do it the easy way, it doesn't work the other way around. That applies to any programming paradigm.
I ran into the same problem. I had a PNG file in a Java package and it wasn't exported in the final JAR along with the sources, which caused the app to crash upon start (file not found).
None of the answers above solved my problem but I found the solution on the Gradle forums. I added the following to my build.gradle
file :
sourceSets.main.resources.srcDirs = [ "src/" ]
sourceSets.main.resources.includes = [ "**/*.png" ]
It tells Gradle to look for resources in the src
folder, and ask it to include only PNG files.
EDIT: Beware that if you're using Eclipse, this will break your run configurations and you'll get a main class not found
error when trying to run your program. To fix that, the only solution I've found is to move the image(s) to another directory, res/
for example, and to set it as srcDirs
instead of src/
.
To get Single/Multiple values without regular expression
// For Single
var value = inputString.Split("<tag1>", '</tag1>')[1];
// For Multiple
var values = inputString.Split("<tag1>", '</tag1>').Where((_, index) => index % 2 != 0);
I've always used singular simply because that's what I was taught. However, while creating a new schema recently, for the first time in a long time, I actively decided to maintain this convention simply because... it's shorter. Adding an 's' to the end of every table name seems as useless to me as adding 'tbl_' in front of every one.
Concatenate the attribute selectors:
input[name="Sex"][value="M"]
You seem to be looking for pass-by-reference, to do that make your function look this way (note the ampersand):
function foo(&$array)
{
$array[3]=$array[0]+$array[1]+$array[2];
}
Alternately, you can assign the return value of the function to a variable:
function foo($array)
{
$array[3]=$array[0]+$array[1]+$array[2];
return $array;
}
$waffles = foo($waffles)
Position your <div>
absolutely at the bottom and don't forget to give div.A

width: 100%;
position: absolute;
bottom: -29px;
}?

You can use Popen in subprocess
as they suggest.

a = os.popen('pwd').readlines()
The answer by Steve Jessop explains well, why you can't use std::map::operator[]
on a const std::map
. Gabe Rainbow's answer suggests a nice alternative. I'd just like to provide some example code on how to use map::at()
. So, here is an enhanced example of your function()
:
void function(const MAP &map, const std::string &findMe) {
try {
const std::string& value = map.at(findMe);
std::cout << "Value of key \"" << findMe.c_str() << "\": " << value.c_str() << std::endl;
// TODO: Handle the element found.
}
catch (const std::out_of_range&) {
std::cout << "Key \"" << findMe.c_str() << "\" not found" << std::endl;
// TODO: Deal with the missing element.
}
}
And here is an example main()
function:
int main() {
MAP valueMap;
valueMap["string"] = "abc";
function(valueMap, "string");
function(valueMap, "strong");
return 0;
}
Output:
Value of key "string": abc
Key "strong" not found
Why do you want to use Firebug if Safari already comes with great Developer tools? :)
As Matt said, you can enable them from the preferences menu.
Here you will find an overview, summarized, of the Safari's Web inspector, and how to use it:
Add this android:screenOrientation="landscape"
to your <activity>
tag in the manifest for the specific activity that you want to be in landscape.
Edit:
To toggle the orientation from the Activity
code, call setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE)
other parameters can be found in the Android docs for ActivityInfo.
I played with this two weeks ago, it's very simple. The only problem is that all the tutorials just talk about saving the image locally. This is how I did it:
1) I set up a form so I can use a POST method.
2) When the user is done drawing, he can click the "Save" button.
3) When the button is clicked I take the image data and put it into a hidden field. After that I submit the form.
document.getElementById('my_hidden').value = canvas.toDataURL('image/png');
document.forms["form1"].submit();
4) When the form is submited I have this small php script:
<?php
$upload_dir = somehow_get_upload_dir(); //implement this function yourself
$img = $_POST['my_hidden'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = $upload_dir."image_name.png";
$success = file_put_contents($file, $data);
header('Location: '.$_POST['return_url']);
?>
Collection is the Super interface of List so every Java list is as well an instance of collection. Collections are only iterable sequentially (and in no particular order) whereas a List allows access to an element at a certain position via the get(int index)
method.
You can use the WebClient
Using System.Net;
WebClient client = new WebClient();
string downloadString = client.DownloadString("http://www.gooogle.com");
Yes:
>>> from collections import Counter
>>> x = Counter({'a':5, 'b':3, 'c':7})
Using the sorted keyword key and a lambda function:
>>> sorted(x.items(), key=lambda i: i[1])
[('b', 3), ('a', 5), ('c', 7)]
>>> sorted(x.items(), key=lambda i: i[1], reverse=True)
[('c', 7), ('a', 5), ('b', 3)]
This works for all dictionaries. However Counter
has a special function which already gives you the sorted items (from most frequent, to least frequent). It's called most_common()
:
>>> x.most_common()
[('c', 7), ('a', 5), ('b', 3)]
>>> list(reversed(x.most_common())) # in order of least to most
[('b', 3), ('a', 5), ('c', 7)]
You can also specify how many items you want to see:
>>> x.most_common(2) # specify number you want
[('c', 7), ('a', 5)]

i know it is a controversial topic, and likely i get burned now. but here are my thoughts.
For myself i figured that it is best to avoid classes as long as possible. If i need a complex datatype I use simple struct (C/C++), dict (python), JSON (js), or similar, i.e. no constructor, no class methods, no operator overloading, no inheritance, etc. When using class, you can get carried away by OOP itself (What Design pattern, what should be private, bla bla), and loose focus on the essential stuff you wanted to code in the first place.
If your project grows big and messy, then OOP starts to make sense because some sort of helicopter-view system architecture is needed. "function vs class" also depends on the task ahead of you.
I wrote a JavaScript function that returns the four coordinates of a square bounding box, given a distance and a pair of coordinates:
'use strict';
/**
* @param {number} distance - distance (km) from the point represented by centerPoint
* @param {array} centerPoint - two-dimensional array containing center coords [latitude, longitude]
* @description
* Computes the bounding coordinates of all points on the surface of a sphere
* that has a great circle distance to the point represented by the centerPoint
* argument that is less or equal to the distance argument.
* Technique from: Jan Matuschek <http://JanMatuschek.de/LatitudeLongitudeBoundingCoordinates>

*/
getBoundingBox = function (centerPoint, distance) {
var MIN_LAT, MAX_LAT, MIN_LON, MAX_LON, R, radDist, degLat, degLon, radLat, radLon, minLat, maxLat, minLon, maxLon, deltaLon;
if (distance < 0) {
return 'Illegal arguments';
}
// helper functions (degrees<–>radians)
Number.prototype.degToRad = function () {
return this * (Math.PI / 180);
};
Number.prototype.radToDeg = function () {
return (180 * this) / Math.PI;
};
// coordinate limits
MIN_LAT = (-90).degToRad();
MAX_LAT = (90).degToRad();
MIN_LON = (-180).degToRad();
MAX_LON = (180).degToRad();
// Earth's radius (km)
R = 6378.1;
// angular distance in radians on a great circle
radDist = distance / R;
// center point coordinates (deg)
degLat = centerPoint[0];
degLon = centerPoint[1];
// center point coordinates (rad)
radLat = degLat.degToRad();
radLon = degLon.degToRad();
// minimum and maximum latitudes for given distance
minLat = radLat - radDist;
maxLat = radLat + radDist;
// minimum and maximum longitudes for given distance
minLon = void 0;
maxLon = void 0;
// define deltaLon to help determine min and max longitudes
deltaLon = Math.asin(Math.sin(radDist) / Math.cos(radLat));
if (minLat > MIN_LAT && maxLat < MAX_LAT) {
minLon = radLon - deltaLon;
maxLon = radLon + deltaLon;
if (minLon < MIN_LON) {
minLon = minLon + 2 * Math.PI;
}
if (maxLon > MAX_LON) {
maxLon = maxLon - 2 * Math.PI;
}
}
// a pole is within the given distance
else {
minLat = Math.max(minLat, MIN_LAT);
maxLat = Math.min(maxLat, MAX_LAT);
minLon = MIN_LON;
maxLon = MAX_LON;
}
return [
minLon.radToDeg(),
minLat.radToDeg(),
maxLon.radToDeg(),

];
};
It is very simple. For example : in you JS controller use this:
$scope.inputngmodel.$valid = false;
or
$scope.inputngmodel.$invalid = true;
or
$scope.formname.inputngmodel.$valid = false;
or
$scope.formname.inputngmodel.$invalid = true;
All works for me for different requirement. Hit up if this solve your problem.

If you are using Java for OpenCV, then you can use the following code.
Mat img = src.clone(); //Clone from the original image
img.setTo(new Scalar(255,255,255)); //This sets the whole image to white, it is R,G,B value
I have also been suffering from this problem, but finally got the solution, Initially directly the load the iframe url in browser like small popup then only access the session values inside the iframe.

Am I going to be downmodded for suggesting that the Stack Overflow podcast is hilariously bad as a podcast? Anywho, you can find it, and a number of not-bad podcasts at itconversations.com.
As this question asked for a "good" rather than "exhaustive" list, then this is obviously just my opinion. My opinion bounces between .NET and Java and just geek. And obvious omissions would reflect my opinion on "good". (Ahem, DNR.)
The rest of these are easily found by doing a podcast search in iTunes, or just googling (I'll do some repeating here to condense the list):
like this:
/\<word\>
\<
means beginning of a word, and \>
means the end of a word,
Adding @Roe's comment:
VIM provides a shortcut for this. If you already have word on screen and you want to find other instances of it, you can put the cursor on the word and press '*'
to search forward in the file or '#'
to search backwards.
Alternatively to using MARS (MultipleActiveResultSets) you can write your code so you dont open multiple result sets.
What you can do is to retrieve the data to memory, that way you will not have the reader open. It is often caused by iterating through a resultset while trying to open another result set.
Sample Code:
public class MyContext : DbContext
{
public DbSet<Blog> Blogs { get; set; }
public DbSet<Post> Posts { get; set; }
}
public class Blog
{
public int BlogID { get; set; }
public virtual ICollection<Post> Posts { get; set; }
}
public class Post
{
public int PostID { get; set; }
public virtual Blog Blog { get; set; }
public string Text { get; set; }
}
Lets say you are doing a lookup in your database containing these:
var context = new MyContext();
//here we have one resultset
var largeBlogs = context.Blogs.Where(b => b.Posts.Count > 5);
foreach (var blog in largeBlogs) //we use the result set here
{
//here we try to get another result set while we are still reading the above set.
var postsWithImportantText = blog.Posts.Where(p=>p.Text.Contains("Important Text"));
}
We can do a simple solution to this by adding .ToList() like this:
var largeBlogs = context.Blogs.Where(b => b.Posts.Count > 5).ToList();
This forces entityframework to load the list into memory, thus when we iterate though it in the foreach loop it is no longer using the data reader to open the list, it is instead in memory.
I realize that this might not be desired if you want to lazyload some properties for example. This is mostly an example that hopefully explains how/why you might get this problem, so you can make decisions accordingly
After ten years, you can read this training explanation on the official documentation.

Mine was quite straightforward if you are on a Mac try:
brew install postgres
This will tell you if you have it already install and what version or install the latest version for you if not then run
brew upgrade postgresql
This will make sure you have the latest version installed then finally
brew services start postgresql
This will start the service again. I hope this helps someone.

To do this for a specific target, you can do the following:

You should do this if you have more than one target that you're building and you don't want them all to use the same flags. Also see the official documentation on target_compile_definitions.
It is possible to scaffold a view. Just use -Tables the way you would to scaffold a table, only use the name of your view. E.g., If the name of your view is ‘vw_inventory’, then run this command in the Package Manager Console (substituting your own information for "My..."):
PM> Scaffold-DbContext "Server=MyServer;Database=MyDatabase;user id=MyUserId;password=MyPassword" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Temp -Tables vw_inventory
This command will create a model file and context file in the Temp directory of your project. You can move the model file into your models directory (remember to change the namespace name). You can copy what you need from the context file and paste it into the appropriate existing context file in your project.
Note: If you want to use your view in an integration test using a local db, you'll need to create the view as part of your db setup. If you’re going to use the view in more than one test, make sure to add a check for existence of the view. In this case, since the SQL ‘Create View’ statement is required to be the only statement in the batch, you’ll need to run the create view as dynamic Sql within the existence check statement. Alternatively you could run separate ‘if exists drop view…’, then ‘create view’ statements, but if multiple tests are running concurrently, you don’t want the view to be dropped if another test is using it. Example:
void setupDb() {
...
SomeDb.Command(db => db.Database.ExecuteSqlRaw(CreateInventoryView()));
...
}
public string CreateInventoryView() => @"
IF OBJECT_ID('[dbo].[vw_inventory]') IS NULL
BEGIN EXEC('CREATE VIEW [dbo].[vw_inventory] AS
SELECT ...')
END";
Oracle
stores only the fractions up to second in a DATE
field.
Use TIMESTAMP
instead:
SELECT TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9')
FROM dual
, possibly casting it to a DATE
then:
SELECT CAST(TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9') AS DATE)
FROM dual
Paul Irish has a way to do this that covers most of the common problems. See his bullet-proof @font-face article:
The final variant, which stops unnecessary data from being downloaded by IE, and works in IE8, Firefox, Opera, Safari, and Chrome looks like this:
@font-face {
font-family: 'Graublau Web';
src: url('GraublauWeb.eot');
src: local('Graublau Web Regular'), local('Graublau Web'),
url("GraublauWeb.woff") format("woff"),
url("GraublauWeb.otf") format("opentype"),
url("GraublauWeb.svg#grablau") format("svg");
}
He also links to a generator that will translate the fonts into all the formats you need.
As others have already specified, this will only work in the latest generation of browsers. Your best bet is to use this in conjunction with something like Cufon, and only load Cufon if the browser doesn't support @font-face
.
Rda is just a short name for RData. You can just save(), load(), attach(), etc. just like you do with RData.
Rds stores a single R object. Yet, beyond that simple explanation, there are several differences from a "standard" storage. Probably this R-manual Link to readRDS() function clarifies such distinctions sufficiently.
So, answering your questions:
Or you can use one SQL-command instead of create and call stored procedure

Remove elements using indexes array:
Array of Strings and indexes
let animals = ["cats", "dogs", "chimps", "moose", "squarrel", "cow"]
let indexAnimals = [0, 3, 4]
let arrayRemainingAnimals = animals
.enumerated()
.filter { !indexAnimals.contains($0.offset) }
.map { $0.element }
print(arrayRemainingAnimals)
//result - ["dogs", "chimps", "cow"]
Array of Integers and indexes
var numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
let indexesToRemove = [3, 5, 8, 12]
numbers = numbers
.enumerated()
.filter { !indexesToRemove.contains($0.offset) }
.map { $0.element }
print(numbers)
//result - [0, 1, 2, 4, 6, 7, 9, 10, 11]
Remove elements using element value of another array
Arrays of integers
let arrayResult = numbers.filter { element in
return !indexesToRemove.contains(element)
}
print(arrayResult)
//result - [0, 1, 2, 4, 6, 7, 9, 10, 11]
Arrays of strings
let arrayLetters = ["a", "b", "c", "d", "e", "f", "g", "h", "i"]
let arrayRemoveLetters = ["a", "e", "g", "h"]
let arrayRemainingLetters = arrayLetters.filter {
!arrayRemoveLetters.contains($0)
}
print(arrayRemainingLetters)
//result - ["b", "c", "d", "f", "i"]
You might wanna clear the old Image before setting a new Image.
You also need to update the Canvas size for a new Image.
This is how I am doing in my project:
// on image load update Canvas Image
this.image.onload = () => {
// Clear Old Image and Reset Bounds
canvasContext.clearRect(0, 0, this.canvas.width, this.canvas.height);
this.canvas.height = this.image.height;
this.canvas.width = this.image.width;
// Redraw Image
canvasContext.drawImage(
this.image,
0,
0,
this.image.width,
this.image.height
);
};
In repo_a:
git remote add -f b path/to/repo_b.git
git remote update
git diff master remotes/b/master
git remote rm b
Another option besides those above is:
df = df.groupby(df.columns, axis = 1).transform(lambda x: x.fillna(x.mean()))
It's less elegant than previous responses for mean, but it could be shorter if you desire to replace nulls by some other column function.
You want to focus on immutability in Scala generally by eliminating any vars. Readability is still important for your fellow man so:
Try:
scala> val list = for(i <- 1 to 10) yield i
list: scala.collection.immutable.IndexedSeq[Int] = Vector(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
You probably don't even need to convert to a list in most cases :)
The indexed seq will have everything you need:
That is, you can now work on that IndexedSeq:
scala> list.foldLeft(0)(_+_)
res0: Int = 55
Right click 'libraries' in the project list, then click add.
Inputs -
tableView.beginUpdates() tableView.endUpdates() these functions will not call
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {}
But, if you do, tableView.reloadRows(at: [selectedIndexPath! as IndexPath], with: .none)
It will call the func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {} this function.
I guess a generic client-side JavaScript compression implementation would be a very expensive operation in terms of processing time as opposed to transfer time of a few more HTTP packets with uncompressed payload.
Have you done any testing that would give you an idea how much time there is to save? I mean, bandwidth savings can't be what you're after, or can it?
If you're using C# 3.0 you can use linq, way better and way more elegant:
List<int> myList = GetListOfIntsFromSomewhere();
// This will filter out the list of ints that are > than 7, Where returns an
// IEnumerable<T> so a call to ToList is required to convert back to a List<T>.
List<int> filteredList = myList.Where( x => x > 7).ToList();
If you can't find the .Where
, that means you need to import using System.Linq;
at the top of your file.
If this is for a script, you can use:
git fetch
$(git rev-parse HEAD) == $(git rev-parse @{u})
(Note: the benefit of this vs. previous answers is that you don't need a separate command to get the current branch name. "HEAD" and "@{u}" (the current branch's upstream) take care of it. See "git rev-parse --help" for more details.)
If the purpose of a dark theme is to make your eyes comfortable, you can enable High Contrast settings of your Operating System. For example in Windows 8.1 you can turn on - off High Contrast by pressing ALT + left SHIFT + PRINT SCREEN
This will make entire OS in dark mode, not only eclipse. Below is a sample screenshot of Eclipse with High Contrast enabled

Have you tried using dictionary comprehension with dictionary mapping:
a = {'a': 1, 'b': 2}
b = {'c': 3, 'd': 4}
c = {**a, **b}
# c = {"a": 1, "b": 2, "c": 3, "d": 4}
Another way of doing is by Using dict(iterable, **kwarg)
c = dict(a, **b)
# c = {'a': 1, 'b': 2, 'c': 3, 'd': 4}
In Python 3.9 you can add two dict using union | operator
# use the merging operator |
c = a | b
# c = {'a': 1, 'b': 2, 'c': 3, 'd': 4}
Just set the value of required height in a listview height attribute inside a parent scrollview. It will scroll along with other parents child item.
I guess you're coming from a windows background. So i'll contrast them (i'm kind of new to linux too). I found user's reply to my comment, to be useful in figuring things out.
In Windows, a variable can be permanent or not. The term Environment variable includes a variable set in the cmd shell with the SET command, as well as when the variable is set within the windows GUI, thus set in the registry, and becoming viewable in new cmd windows. e.g. documentation for the set command in windows https://technet.microsoft.com/en-us/library/bb490998.aspx "Displays, sets, or removes environment variables. Used without parameters, set displays the current environment settings." In Linux, set does not display environment variables, it displays shell variables which it doesn't call/refer to as environment variables. Also, Linux doesn't use set to set variables(apart from positional parameters and shell options, which I explain as a note at the end), only to display them and even then only to display shell variables. Windows uses set for setting and displaying e.g. set a=5, linux doesn't.
In Linux, I guess you could make a script that sets variables on bootup, e.g. /etc/profile
or /etc/.bashrc
but otherwise, they're not permanent. They're stored in RAM.
There is a distinction in Linux between shell variables, and environment variables. In Linux, shell variables are only in the current shell, and Environment variables, are in that shell and all child shells.
You can view shell variables with the set
command (though note that unlike windows, variables are not set in linux with the set command).
set -o posix; set
(doing that set -o posix once first, helps not display too much unnecessary stuff). So set
displays shell variables.
You can view environment variables with the env
command
shell variables are set with e.g. just a = 5
environment variables are set with export, export also sets the shell variable
Here you see shell variable zzz set with zzz = 5, and see it shows when running set
but doesn't show as an environment variable.
Here we see yyy set with export, so it's an environment variable. And see it shows under both shell variables and environment variables
$ zzz=5
$ set | grep zzz
zzz=5
$ env | grep zzz
$ export yyy=5
$ set | grep yyy
yyy=5
$ env | grep yyy
yyy=5
$
other useful threads
https://unix.stackexchange.com/questions/176001/how-can-i-list-all-shell-variables
https://askubuntu.com/questions/26318/environment-variable-vs-shell-variable-whats-the-difference
Note- one point which elaborates a bit and is somewhat corrective to what i've written, is that, in linux bash, 'set' can be used to set "positional parameters" and "shell options/attributes", and technically both of those are variables, though the man pages might not describe them as such. But still, as mentioned, set won't set shell variables or environment variables). If you do set asdf
then it sets $1 to asdf, and if you do echo $1
you see asdf. If you do set a=5
it won't set the variable a, equal to 5. It will set the positional parameter $1 equal to the string of "a=5". So if you ever saw set a=5 in linux it's probably a mistake unless somebody actually wanted that string a=5, in $1. The other thing that linux's set can set, is shell options/attributes. If you do set -o you see a list of them. And you can do for example set -o verbose
, off, to turn verbose on(btw the default happens to be off but that makes no difference to this). Or you can do set +o verbose
to turn verbose off. Windows has no such usage for its set command.
There is a neat library available on GitHub:
https://github.com/serkanyersen/ifvisible.js
Example:
// If page is visible right now
if( ifvisible.now() ){
// Display pop-up
openPopUp();
}
I've tested version 1.0.1 on all browsers I have and can confirm that it works with:
... and probably all newer versions.
Doesn't fully work with:
.now()
always returns true
for me)You can use in this way using bootstrap css. Just remove the active class if already assinged to any row and reassign to the current row.
$(".table tr").each(function () {
$(this).attr("class", "");
});
$(this).attr("class", "active");
Well, you can't add styling using pseudo selectors like :hover
, :after
, :nth-child
, or anything like that using jQuery.
If you want to add a CSS rule like that you have to create a <style>
element and add that :hover
rule to it just like you would in CSS. Then you would have to add that <style>
element to the page.
Using the .hover
function seems to be more appropriate if you can't just add the css to a stylesheet, but if you insist you can do:
$('head').append('<style>.myclass:hover div {background-color : red;}</style>')
If you want to read more on adding CSS with javascript you can check out one of David Walsh's Blog posts.
You need to use ContextCompat.getColor(), which is part of the Support V4 Library (so it will work for all the previous API).
ContextCompat.getColor(context, R.color.my_color)
As specified in the documentation, "Starting in M, the returned color will be styled for the specified Context's theme". SO no need to worry about it.
You can add the Support V4 library by adding the following to the dependencies array inside your app build.gradle:
compile 'com.android.support:support-v4:23.0.1'
The short answer is that history.pushState
(not History.pushState
, which would throw an exception, the window
part is optional) will never do what you suggest.
If pages are refreshing, then it is caused by other things that you are doing (for example, you might have code running that goes to a new location in the case of the address bar changing).
history.pushState({urlPath:'/page2.php'},"",'/page2.php')
works exactly like it is supposed to in the latest versions of Chrome, IE and Firefox for me and my colleagues.
In fact you can put whatever you like into the function: history.pushState({}, '', 'So long and thanks for all the fish.not a real file')
.
If you post some more code (with special attention for code nearby the history.pushState
and anywhere document.location
is used), then we'll be more than happy to help you figure out where exactly this issue is coming from.
If you post more code, I'll update this answer (I have your question favourited) :).
I found setting all AllowUser...
properties to false
, ReadOnly
to true
, RowHeadersVisible
to false
, ScollBars
to None
, then faking the prevention of selection worked best for me. Not setting Enabled
to false
still allows the user to copy the data from the grid.
The following code also cleans up the look when you want a simple display grid (assuming rows are the same height):
int width = 0;
for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
width += dataGridView1.Columns[i].Width;
}
dataGridView1.Width = width;
dataGridView1.Height = dataGridView1.Rows[0].Height*(dataGridView1.Rows.Count+1);

I use combination of several plugins - for the basic assignment of roles and permission I use Role Strategy Plugin.
When I need to split some role depending on parameters (e.g. everybody with job-runner is able to run jobs, but user only user UUU is allowed to run the deployment job to deploy on machine MMM), I use Python Plugin and define a python script as first build step and end with sys.exit(-1) when the job is forbidden to be run with the given combination of parameters.
Build User Vars Plugin provides me the information about the user executing the job as environment variables.
E.g:
import os
import sys
print os.environ["BUILD_USER"], "deploying to", os.environ["target_host"]
# only some users are allowed to deploy to servers "MMM"
mmm_users = ["UUU"]
if os.environ["target_host"] != "MMM" or os.environ["BUILD_USER"] in mmm_users:
print "access granted"
else:
print "access denied"
sys.exit(-1)
Static Typing: The languages such as Java and Scala are static typed.
The variables have to be defined and initialized before they are used in a code.
for ex. int x; x = 10;
System.out.println(x);
Dynamic Typing: Perl is an dynamic typed language.
Variables need not be initialized before they are used in code.
y=10; use this variable in the later part of code
Nothing, they are synonymous (Response.Write
is simply a shorter way to express the act of writing to the response output).
If you are curious, the implementation of HttpResponse.Write
looks like this:
public void Write(string s)
{
this._writer.Write(s);
}
And the implementation of HttpResponse.Output
is this:
public TextWriter Output
{
get
{
return this._writer;
}
}
So as you can see, Response.Write
and Response.Output.Write
are truly synonymous expressions.
In order to avoid having to fully specify the git push command you could alternatively modify your git config file:
[remote "gerrit"]
url = https://your.gerrit.repo:44444/repo
fetch = +refs/heads/master:refs/remotes/origin/master
push = refs/heads/master:refs/for/master
Now you can simply:
git fetch gerrit
git push gerrit
This is according to Gerrit
sudo apt-get install php5.6-curl
and restart the web browser.
You can check the modules by running php -m | grep curl
An old question, but I'd like to offer my solution anyway. It's based on acceptance that model objects too require some additional functionality while it's awkward to place it within the models.py. Heavy business logic may be written separately depending on personal taste, but I at least like the model to do everything related to itself. This solution also supports those who like to have all the logic placed within models themselves.
As such, I devised a hack that allows me to separate logic from model definitions and still get all the hinting from my IDE.
The advantages should be obvious, but this lists a few that I have observed:
I have been using this with Python 3.4 and greater and Django 1.8 and greater.
app/models.py
....
from app.logic.user import UserLogic
class User(models.Model, UserLogic):
field1 = models.AnyField(....)
... field definitions ...
app/logic/user.py
if False:
# This allows the IDE to know about the User model and its member fields
from main.models import User
class UserLogic(object):
def logic_function(self: 'User'):
... code with hinting working normally ...
The only thing I can't figure out is how to make my IDE (PyCharm in this case) recognise that UserLogic is actually User model. But since this is obviously a hack, I'm quite happy to accept the little nuisance of always specifying type for self
parameter.
I forget where I saw this definition, but I think it's pretty nice.
A library is a module that you call from your code, and a framework is a module which calls your code.
http://fortawesome.github.io/Font-Awesome/examples/
<i class="icon-thumbs-up icon-3x main-color"></i>
Here I have defined a global style in my CSS where main-color is a class, in my case it is a light blue hue. I find that using inline styles on Icons with Font Awesome works well, esp in the case when you name your colors semantically, i.e. nav-color if you want a separate color for that, etc.
In this example on their website, and how I have written in my example as well, the newest version of Font Awesome has changed the syntax slightly of adjusting the size.Before it used to be:
icon-xxlarge
where now I have to use:
icon-3x
Of course, this all depends on what version of Font Awesome you have installed on your environment. Hope this helps.

I guess it's a little too late now however the only time it does make a difference is when you set up HTML signatures on MS Outlook (even 2010). It's just not able to handle .html extensions, only .htm
Individual element copy, it seems to work for me with just a simple example.
maps := map[string]int {
"alice":12,
"jimmy":15,
}
maps2 := make(map[string]int)
for k2,v2 := range maps {
maps2[k2] = v2
}
maps2["miki"]=rand.Intn(100)
fmt.Println("maps: ",maps," vs. ","maps2: ",maps2)
There is no limit according to the HTTP protocol itself, but implementations will have a practical upper limit. I have sent data exceeding 4 GB using POST to Apache, but some servers did have a limit of 4 GB at the time.
If you have names of the element and not id we can achieve the undefined check on all text elements (for example) as below and fill them with a default value say 0.0:
var aFieldsCannotBeNull=['ast_chkacc_bwr','ast_savacc_bwr'];
jQuery.each(aFieldsCannotBeNull,function(nShowIndex,sShowKey) {
var $_oField = jQuery("input[name='"+sShowKey+"']");
if($_oField.val().trim().length === 0){
$_oField.val('0.0')
}
})
You can use CSS3 media query for this. Write like this:
CSS
.wrapper {
border : 2px solid #000;
overflow:hidden;
}
.wrapper div {
min-height: 200px;
padding: 10px;
}
#one {
background-color: gray;
float:left;
margin-right:20px;
width:140px;
border-right:2px solid #000;
}
#two {
background-color: white;
overflow:hidden;
margin:10px;
border:2px dashed #ccc;
min-height:170px;
}
@media screen and (max-width: 400px) {
#one {
float: none;
margin-right:0;
width:auto;
border:0;

}
}

I had this problem on windows.
This is the solution:
To pass '' for NULL you should disable STRICT_MODE (which is enabled by default on Windows installations)
BTW It's funny to pass '' for NULL. I don't know why they let this kind of behavior.
It's not that different in bash
.
workdone=0
while : ; do
...
if [ "$workdone" -ne 0 ]; then
break
fi
done
:
is the no-op command; its exit status is always 0, so the loop runs until workdone
is given a non-zero value.
There are many ways you could set and test the value of workdone
in order to exit the loop; the one I show above should work in any POSIX-compatible shell.
Yes you can; it works on Android too:
tel: phone_number
Calls the entered phone number. Valid telephone numbers as defined in the IETF RFC 3966 are accepted. Valid examples include the following:* tel:2125551212 * tel: (212) 555 1212
The Android browser uses the Phone app to handle the “tel” scheme, as defined by RFC 3966.
Clicking a link like:
<a href="tel:2125551212">2125551212</a>
on Android will bring up the Phone app and pre-enter the digits for 2125551212 without autodialing.
Have a look to RFC3966
Here's a way that allows for ties for the cut-off score.
author_count = Author.objects.count()
cut_off_score = Author.objects.order_by('-score').values_list('score')[min(30, author_count)]
top_authors = Author.objects.filter(score__gte=cut_off_score).order_by('last_name')
You may get more than 30 authors in top_authors this way and the min(30,author_count)
is there incase you have fewer than 30 authors.
If you would like to query all columns
List<Users> list_users = new List<Users>();
MySqlConnection cn = new MySqlConnection("connection");
MySqlCommand cm = new MySqlCommand("select * from users",cn);
try
{
cn.Open();
MySqlDataReader dr = cm.ExecuteReader();
while (dr.Read())
{
list_users.Add(new Users(dr));
}
}
catch { /* error */ }
finally { cn.Close(); }
The User's constructor would do all the "dr.GetString(i)"
I had the same issue when my server free disk space available was 0
You can use the command (there must be ample space for the mysql files)

It is not that complicated actually. Relevant Qt widgets are in matplotlib.backends.backend_qt4agg
. FigureCanvasQTAgg
and NavigationToolbar2QT
are usually what you need. These are regular Qt widgets. You treat them as any other widget. Below is a very simple example with a Figure
, Navigation
and a single button that draws some random data. I've added comments to explain things.

from matplotlib.figure import Figure
import random
class Window(QtGui.QDialog):
def __init__(self, parent=None):
super(Window, self).__init__(parent)
# a figure instance to plot on
self.figure = Figure()
# this is the Canvas Widget that displays the `figure`
# it takes the `figure` instance as a parameter to __init__
self.canvas = FigureCanvas(self.figure)
# this is the Navigation widget
# it takes the Canvas widget and a parent
self.toolbar = NavigationToolbar(self.canvas, self)
# Just some button connected to `plot` method
self.button = QtGui.QPushButton('Plot')
self.button.clicked.connect(self.plot)
# set the layout
layout = QtGui.QVBoxLayout()
layout.addWidget(self.toolbar)
layout.addWidget(self.canvas)
layout.addWidget(self.button)
self.setLayout(layout)
def plot(self):
''' plot some random stuff '''
# random data
data = [random.random() for i in range(10)]
# create an axis
ax = self.figure.add_subplot(111)
# discards the old graph
ax.clear()
# plot data
ax.plot(data, '*-')
# refresh canvas
self.canvas.draw()
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
main = Window()

$categories = Category::all()->sortByDesc("created_at");
Span is considered an in-line element. As such is basically constrains itself to the content within it. It more or less is transparent.
Think of it having the behavior of the 'b' tag.
It can be performed like <span style='font-weight: bold;'>bold text</span>
div is a block element.
Just as alternative you may consider using execs... (I wouldn't recommend it though)
exec { 'this will output stuff':
path => '/bin',
command => 'echo Hello World!',
logoutput => true,
}
So when you run puppet you should find some output like so:
notice: /Stage[main]//Exec[this will output stuff]/returns: Hello World!
notice: /Stage[main]//Exec[this will output stuff]/returns: executed successfully
notice: Finished catalog run in 0.08 seconds
The first line being logged output.
For siblings package imports, you can use either the insert or the append method of the [sys.path][2] module:
if __name__ == '__main__' and if __package__ is None:
import sys
from os import path
sys.path.append( path.dirname( path.dirname( path.abspath(__file__) ) ) )
import api
This will work if you are launching your scripts as follows:
python examples/example_one.py
python tests/test_one.py
On the other hand, you can also use the relative import:
if __name__ == '__main__' and if __package__ is not None:
import ..api.api
In this case you will have to launch your script with the '-m' argument (note that, in this case, you must not give the '.py' extension):
python -m packageName.examples.example_one
python -m packageName.tests.test_one
Of course, you can mix the two approaches, so that your script will work no matter how it is called:
if __name__ == '__main__':
if __package__ is None:
import sys
from os import path
sys.path.append( path.dirname( path.dirname( path.abspath(__file__) ) ) )
import api
else:
import ..api.api
In zsh you can use
=time ...
In bash or zsh you can use
command time ...
These (by different mechanisms) force an external command to be used.
I have encountered this issue!
Luckily, I determine 2 ways and understand some things but the rest is not clear.
Hope someone discuss or support if you know.
List<Person> person = this.PersonRepository.findById(0)
person.setName("Neo");
This.PersonReository.save(person);
a = np.arange(18).reshape(9,2)
b = a.reshape(3,3,2).swapaxes(0,2)
# a:
array([[ 0, 1],
[ 2, 3],
[ 4, 5],
[ 6, 7],
[ 8, 9],
[10, 11],
[12, 13],
[14, 15],
[16, 17]])
# b:
array([[[ 0, 6, 12],
[ 2, 8, 14],
[ 4, 10, 16]],
[[ 1, 7, 13],
[ 3, 9, 15],
[ 5, 11, 17]]])
This prints all elements that contain sub:
for s in filter (lambda x: sub in x, list): print (s)
select cast((1*1.00)/3 AS DECIMAL(16,2)) as Result
Here in this sql first convert to float or multiply by 1.00 .Which output will be a float number.Here i consider 2 decimal places. You can choose what you need.
I know this is old... But I was having the same problem today and found a solution:
Model.find_by_sql
If you want to instantiate the results:
Client.find_by_sql("
SELECT * FROM clients
INNER JOIN orders ON clients.id = orders.client_id
ORDER BY clients.created_at desc
")
# => [<Client id: 1, first_name: "Lucas" >, <Client id: 2, first_name: "Jan">...]
Model.connection.select_all('sql').to_hash
If you just want a hash of values:
Client.connection.select_all("SELECT first_name, created_at FROM clients
WHERE id = '1'").to_hash
# => [
{"first_name"=>"Rafael", "created_at"=>"2012-11-10 23:23:45.281189"},
{"first_name"=>"Eileen", "created_at"=>"2013-12-09 11:22:35.221282"}
]
Result object:
select_all
returns a result
object. You can do magic things with it.
result = Post.connection.select_all('SELECT id, title, body FROM posts')
# Get the column names of the result:
result.columns
# => ["id", "title", "body"]
# Get the record values of the result:
result.rows
# => [[1, "title_1", "body_1"],
[2, "title_2", "body_2"],
...
]
# Get an array of hashes representing the result (column => value):
result.to_hash
# => [{"id" => 1, "title" => "title_1", "body" => "body_1"},
{"id" => 2, "title" => "title_2", "body" => "body_2"},
...
]
# ActiveRecord::Result also includes Enumerable.
result.each do |row|
puts row['title'] + " " + row['body']
end
Sources:
You can change the height of a form by doing the following where you want to change the size (substitute '10' for your size):
this.Height = 10;
This can be done with the width as well:
this.Width = 10;
Dragan B. solution is correct. In my case I needed the buttons to be spaced vertically when stacking so I added the mb-2 property to them.
<div class="btn-toolbar">
<button type="button" class="btn btn-primary mr-2 mb-2">First</button>
<button type="button" class="btn btn-primary mr-2 mb-2">Second</button>
<button type="button" class="btn btn-primary mr-2 mb-2">Third</button>
</div>
I went with this, because it makes sense to me. Comments added for readers!
masterData = [{id: 1, name: "aaaaaaaaaaa"},
{id: 2, name: "Bill"},
{id: 3, name: "ccccccccc"}];
updatedData = [{id: 3, name: "Cat"},
{id: 1, name: "Apple"}];
updatedData.forEach(updatedObj=> {
// For every updatedData object (dataObj), find the array index in masterData where the IDs match.
let indexInMasterData = masterData.map(masterDataObj => masterDataObj.id).indexOf(updatedObj.id); // First make an array of IDs, to use indexOf().
// If there is a matching ID (and thus an index), replace the existing object in masterData with the updatedData's object.
if (indexInMasterData !== undefined) masterData.splice(indexInMasterData, 1, updatedObj);
});
/* masterData becomes [{id: 1, name: "Apple"},
{id: 2, name: "Bill"},
{id: 3, name: "Cat"}]; as you want.`*/
Starting with Firefox 65 an about:config
flag exists now so console API calls like console.log()
land in the output stream and thus the log file (see (https://github.com/mozilla/geckodriver/issues/284#issuecomment-458305621).
profile = new FirefoxProfile();
profile.setPreference("devtools.console.stdout.content", true);
In app.config file (or .exe.config) you can add or change the "receiveTimeout" property in binding. like this
<binding name="WebServiceName" receiveTimeout="00:00:59" />
This worked for me. Each month on X axis
str_month_list = ['January','February','March','April','May','June','July','August','September','October','November','December']
ax.set_xticks(range(0,12))
ax.set_xticklabels(str_month_list)
The jQuery DataTables plug-in is one excellent way to achieve excel-like fixed column(s) and headers.
Note the examples section of the site and the "extras".
http://datatables.net/examples/
http://datatables.net/extras/
The "Extras" section has tools for fixed columns and fixed headers.
Fixed Columns
http://datatables.net/extras/fixedcolumns/
(I believe the example on this page is the one most appropriate for your question.)
Fixed Header

You need to install the DOM extension. You can do so on Debian / Ubuntu using:
sudo apt-get install php-dom
And on Centos / Fedora / Red Hat:
yum install php-xml
If you get conflicts between PHP packages, you could try to see if the specific PHP version package exists instead: e.g. php53-xml
if your system runs PHP5.3.
Highlight the column and then Ctrl + F.
Find and replace
Find ".com"
Replace ".com, "
And then one for .in
Find and replace
Find ".in"
Replace ".in, "
d = DateTime.now.utc
Oops!
That seems to work in Rails, but not vanilla Ruby (and of course that is what the question is asking)
d = Time.now.utc
Does work however.
Is there any reason you need to use DateTime
and not Time
? Time
should include everything you need:
irb(main):016:0> Time.now
=> Thu Apr 16 12:40:44 +0100 2009
The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:
The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?
This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.
In other words, the feature is missing to remove the temptation to use the feature insecurely.
I was wasting my time on this for hours. Fortunately, I found the solution. If you are using bootstrap admin templates (AdminLTE), this problem may show up. Thing is we have to use adminLTE framework plugins.
example: ifChecked
event:
$('input').on('ifChecked', function(event){
alert(event.type + ' callback');
});

I was able to use AWS cli fully authenticated, so for me the issue was within terraform for sure. I tried all the steps above with no success. A reboot fixed it for me, there must be some a cache somewhere in terraform that was causing this issue.
The following adds one line after SearchPattern
.
sed -i '/SearchPattern/aNew Text' SomeFile.txt
It inserts New Text
one line below each line that contains SearchPattern
.
To add two lines, you can use a \
and enter a newline while typing New Text
.
POSIX sed requires a \
and a newline after the a
sed function. [1]
Specifying the text to append without the newline is a GNU sed extension (as documented in the sed
info page), so its usage is not as portable.

You have two choices to do this.
The Quick and Dirty is selecting your files (using ctrl) in Project Explorer view, right-click them, choose Replace with...
and then you choose the best option for you, from Latest from Repository
, or some Branch
version. After getting those files you modify them (with a space, or fix something, your call and commit them to create a newer revision.
A more clean way is choosing Merge
at team menu and navigate through the wizard that will help you to recovery the old version in the actual revision.
Both commands have their command-line equivalents: svn revert
and svn merge
.

Javascript's String.fromCharCode(code1, code2, ..., codeN) takes an infinite number of arguments and returns a string of letters whose corresponding ASCII values are code1, code2, ... codeN. Since 97 is 'a' in ASCII, we can adjust for your indexing by adding 97 to your index.
function indexToChar(i) {
return String.fromCharCode(i+97); //97 in ASCII is 'a', so i=0 returns 'a',
// i=1 returns 'b', etc
}

Old question, but I have only one recent jQuery file (v3.2.1) included (slick is also included, of course), and I still got this problem. I fixed it like this:
function initSlider(selector, options) {
if ($.fn.slick) {
$(selector).slick(options);
} else {
setTimeout(function() {
initSlider(selector, options);
}, 500);
}
}
//example: initSlider('.references', {...slick's options...});
This function tries to apply slick 2 times a second and stops after get it working. I didn't analyze it deep, but I think slick's initialization is being deferred.

I get the same error in Chrome after pasting code copied from jsfiddle.
If you select all the code from a panel in jsfiddle and paste it into the free text editor Notepad++, you should be able to see the problem character as a question mark "?" at the very end of your code. Delete this question mark, then copy and paste the code from Notepad++ and the problem will be gone.

It looks like you're trying to import some google code:

The Excel number for a modern date is most easily calculated as the number of days since 12/30/1899 on the Gregorian calendar.
Excel treats the mythical date 01/00/1900 (i.e., 12/31/1899) as corresponding to 0, and incorrectly treats year 1900 as a leap year. So for dates before 03/01/1900, the Excel number is effectively the number of days after 12/31/1899.
However, Excel will not format any number below 0 (-1 gives you ##########) and so this only matters for "01/00/1900" to 02/28/1900, making it easier to just use the 12/30/1899 date as a base.
A complete function in DB2 SQL that accounts for the leap year 1900 error:
SELECT
DAYS(INPUT_DATE)
- DAYS(DATE('1899-12-30'))
- CASE
WHEN INPUT_DATE < DATE('1900-03-01')
THEN 1
ELSE 0
END
if (Enum.IsDefined(typeof(foo), value))

return (Foo)Enum.Parse(typeof(foo), value);

Hope this helps
Edit This answer got down voted as value in my example is a string, where as the question asked for an int. My applogies; the following should be a bit clearer :-)
Type fooType = typeof(foo);
if (Enum.IsDefined(fooType , value.ToString()))
{
return (Foo)Enum.Parse(fooType , value.ToString());

Place the logo in your public folder under e.g. public/img/logo.png and then refer to the public folder as %PUBLIC_URL%:
<img src="%PUBLIC_URL%/img/logo.png"/>
The use of %PUBLIC_URL% in the above will be replaced with the URL of the public
folder during the build. Only files inside the public
folder can be referenced from the HTML.
Unlike "/img/logo.png" or "logo.png", "%PUBLIC_URL%/img/logo.png" will work correctly both with client-side routing and a non-root public URL. Learn how to configure a non-root public URL by running npm run build
.
To solve this without jQuery .each()
you'd have to fix your code like this:
var listItems = $("#productList").find("li");
var ind, len, product;
for ( ind = 0, len = listItems.length; ind < len; ind++ ) {
product = $(listItems[ind]);
// ...
}
Bugs in your original code:
for ... in
will also loop through all inherited properties; i.e. you will also get a list of all functions that are defined by jQuery.
The loop variable li
is not the list item, but the index to the list item. In that case the index is a normal array index (i.e. an integer)
Basically you are save to use .each()
as it is more comfortable, but espacially when you are looping bigger arrays the code in this answer will be much faster.
For other alternatives to .each()
you can check out this performance comparison:
http://jsperf.com/browser-diet-jquery-each-vs-for-loop
Another approach is to not have the secret on the device in the first place! See Mobile API Security Techniques (especially part 3).
Using the time honored tradition of indirection, share the secret between your API endpoint and an app authentication service.
When your client wants to make an API call, it asks the app auth service to authenticate it (using strong remote attestation techniques), and it receives a time limited (usually JWT) token signed by the secret.
The token is sent with each API call where the endpoint can verify its signature before acting on the request.
The actual secret is never present on the device; in fact, the app never has any idea if it is valid or not, it juts requests authentication and passes on the resulting token. As a nice benefit from indirection, if you ever want to change the secret, you can do so without requiring users to update their installed apps.
So if you want to protect your secret, not having it in your app in the first place is a pretty good way to go.
You got more preparing [for the exam] to do ;-)
The Stack Pointer is a register which holds the address of the next available spot on the stack.
The stack is a area in memory which is reserved to store a stack, that is a LIFO (Last In First Out) type of container, where we store the local variables and return address, allowing a simple management of the nesting of function calls in a typical program.
See this Wikipedia article for a basic explanation of the stack management.
How about something like this
PROXY = "149.215.113.110:70"

"noProxy":None,
"proxyType":"MANUAL",
"class":"org.openqa.selenium.Proxy",
"autodetect":False

# you have to use remote, otherwise you'll have to code it yourself in python to
driver = webdriver.Remote("http://localhost:4444/wd/hub", webdriver.DesiredCapabilities.FIREFOX)
You can read more about it here.
There is no one-to-one correlation. For a really good article please see Efficient String Concatenation in Python:
Building long strings in the Python progamming language can sometimes result in very slow running code. In this article I investigate the computational performance of various string concatenation methods.
Have you tried:
SELECT Cast( 2.555 as decimal(53,8))
This would return 2.55500000
. Is that what you want?
UPDATE:
Apparently you can also use SQL_VARIANT_PROPERTY to find the precision and scale of a value. Example:
SELECT SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Precision'),
SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Scale')
returns 8|7
You may be able to use this in your conversion process...
Ok, the Java code I used was wrong, here comes the right Java class:
import java.io.File;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpVersion;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.ContentBody;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.CoreProtocolPNames;
import org.apache.http.util.EntityUtils;
public class PostFile {
public static void main(String[] args) throws Exception {
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpPost httppost = new HttpPost("http://localhost:9001/upload.php");
File file = new File("c:/TRASH/zaba_1.jpg");
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(file, "image/jpeg");
mpEntity.addPart("userfile", cbFile);
httppost.setEntity(mpEntity);
System.out.println("executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
System.out.println(response.getStatusLine());
if (resEntity != null) {
System.out.println(EntityUtils.toString(resEntity));
}
if (resEntity != null) {
resEntity.consumeContent();
}
httpclient.getConnectionManager().shutdown();
}
}
note using MultipartEntity.
Why would you pass an ArrayList?? It should be possible to just call execute with the params directly:
String curloc = current.toString();
String itemdesc = item.mDescription;
new calc_stanica().execute(itemdesc, curloc)
That how varrargs work, right? Making an ArrayList to pass the variable is double work.
Check your JAVA_HOME path. As systems looks for a java.policy file which is located in JAVA_HOME/jre/lib/security

Here's another variation I've used when wanting to generate a script tag inline (so it executes immediately) without needing any form of escapes:

document.write(script.outerHTML);
</script>
(Note: contrary to most examples on the net, I'm not setting type="text/javascript"
on neither the enclosing tag, nor the generated one: there is no browser not having that as the default, and so it is redundant, but will not hurt either, if you disagree).
I've successfully done this for my website.
Only exception is, the SeaMonkey browser requires HTML code inserted in your <head>
; whereas, the other browsers will still display the favicon.ico without any HTML insertion. Also, any browser other than IE may use other types of images, not just the .ico format. I hope this helps.
Expanding on @folse's answer... I believe a more correct implementation would be...
NSString *appDomain = [[NSBundle mainBundle] bundleIdentifier];
NSDictionary *defaultsDictionary = [[NSUserDefaults standardUserDefaults] persistentDomainForName: appDomain];
for (NSString *key in [defaultsDictionary allKeys]) {
NSLog(@"removing user pref for %@", key);
[[NSUserDefaults standardUserDefaults] removeObjectForKey:key];
}
...calling NSUserDefault's persistentDomainForName: method. As the docs state, the method "Returns a dictionary containing the keys and values in the specified persistent domain." Calling dictionaryRepresentation: instead, will return a dictionary that will likely include other settings as it applies to a wider scope.
If you need to filter out any of the values that are to be reset, then iterating over the keys is the way to do it. Obviously, if you want to just nuke all of the prefs for the app without regard, then one of the other methods posted above is the most efficient.
In case you have only one controller and you want to access every action on root you can skip controller name like this
routes.MapRoute(
"Default",
"{action}/{id}",
new { controller = "Home", action = "Index",
id = UrlParameter.Optional }
);
Similar to Matthew's answer, I just found that you can do the following:
$(this).closest('form').submit();
Wrong: The problem with using the parent functionality is that the field needs to be immediately within the form to work (not inside tds, labels, etc).
I stand corrected: parents (with an s) also works. Thxs Paolo for pointing that out.
<TextView
android:id="@+id/phoneNumber"
android:autoLink="phone"
android:linksClickable="true"
android:text="+91 22 2222 2222"
/>
This is how you can open EditText label assigned number on dialer directly.
