I use laravel 7.x and I used this as a workaround:->get()->pluck('id')->toArray();
it gives back an array of ids [50,2,3]
and this is the whole query I used:
$article_tags = DB::table('tags')
->join('taggables', function ($join) use ($id) {
$join->on('tags.id', '=', 'taggables.tag_id');
$join->where([
['taggable_id', '=', $id],
['taggable_type','=','article']
]);
})->select('tags.id')->get()->pluck('id')->toArray();

It's worth noting, since it's confusing for people new to XML, that the root (or document node) of an XML document is not the top-level element. It's the parent of the top-level element. This is confusing because it doesn't seem like the top-level element can have a parent. Isn't it the top level?
But look at this, a well-formed XML document:
<?xml-stylesheet href="my_transform.xsl" type="text/xsl"?>
<!-- Comments and processing instructions are XML nodes too, remember. -->
<TopLevelElement/>
The root of this document has three children: a processing instruction, a comment, and an element.
So, for example, if you wanted to write a transform that got rid of that comment, but left in any comments appearing anywhere else in the document, you'd add this to the identity transform:
<xsl:template match="/comment()"/>
Even simpler (and more commonly useful), here's an XPath pattern that matches the document's top-level element irrespective of its name: /*
.
I collected some information on the internet and prepared the script that requires no external tool: See my response here. Hope it's helpful.
"But glyph", I hear you asking, "what if I have to determine the maximum value for an opaque type whose maximum might eventually change?" You might continue: "What if it's a typedef in a library I don't control?"
I'm glad you asked, because I just spent a couple of hours cooking up a solution (which I then had to throw away, because it didn't solve my actual problem).
You can use this handy maxof
macro to determine the size of any valid integer type.
#define issigned(t) (((t)(-1)) < ((t) 0))
#define umaxof(t) (((0x1ULL << ((sizeof(t) * 8ULL) - 1ULL)) - 1ULL) | \
(0xFULL << ((sizeof(t) * 8ULL) - 4ULL)))
#define smaxof(t) (((0x1ULL << ((sizeof(t) * 8ULL) - 1ULL)) - 1ULL) | \
(0x7ULL << ((sizeof(t) * 8ULL) - 4ULL)))
#define maxof(t) ((unsigned long long) (issigned(t) ? smaxof(t) : umaxof(t)))
You can use it like so:
int main(int argc, char** argv) {
printf("schar: %llx uchar: %llx\n", maxof(char), maxof(unsigned char));
printf("sshort: %llx ushort: %llx\n", maxof(short), maxof(unsigned short));
printf("sint: %llx uint: %llx\n", maxof(int), maxof(unsigned int));
printf("slong: %llx ulong: %llx\n", maxof(long), maxof(unsigned long));
printf("slong long: %llx ulong long: %llx\n",
maxof(long long), maxof(unsigned long long));
return 0;
}
If you'd like, you can toss a '(t)' onto the front of those macros so they give you a result of the type that you're asking about, and you don't have to do casting to avoid warnings.
This solution worked for me after 2 days of debugging. Change this :
AppRegistry.registerComponent('AppName', () => App);
to
AppRegistry.registerComponent('main', () => App);

If you can provide your image in SVG format and if it is an icon and not a photo so it can be animated with SMIL animations, then it would be definitely the superior alternative to gif images (or even other formats).
SVG images, like other image files, could be used with either standard markup or HTML <img>
element:
![image description](the_path_to/image.svg)
<img src="the_path_to/image.svg" width="128"/>
You can put CSS in the head
of the HTML file, and it will take precedent over a class in an included style sheet.
<style>
.thing{
color: #f00;
}
</style>
This may help a small percentage of people still scratching their heads. Text copied from clipboard into VSCode may have an invisible hard space character preventing wrapping. Check it with HTML inspector
When running the python file, you would normally do this
python app.py
This will display these messages.
To avoid these messsages. Inside the CLI (Command Line Interface), run these commands.
export FLASK_APP=app.py
export FLASK_RUN_HOST=127.0.0.1
export FLASK_ENV=development
export FLASK_DEBUG=0
flask run
This should work perfectlly. :) :)
The target attribute of a link forces the browser to open the destination page in a new browser window. Using _blank
as a target value will spawn a new window every time while using _new
will only spawn one new window and every link clicked with a target value of _new
will replace the page loaded in the previously spawned window
Use CSS:
<input type="text" class="bigText" name=" item" align="left" />
.bigText {
height:30px;
}
Dreamweaver is a poor testing tool. It is not a browser.
ECMAScript 6 introduced the let
statement. You can use it in a for
statement.
var ids:string = [];
for(let result of this.results){
ids.push(result.Id);
}
var exec = require('child_process').exec;
exec('pwd', function callback(error, stdout, stderr){
// result

Use ng-submit and just wrap both inputs in separate form tags:
<div ng-controller="mycontroller">
<form ng-submit="myFunc()">
<input type="text" ng-model="name" <!-- Press ENTER and call myFunc --> />
</form>
<br />
<form ng-submit="myFunc()">
<input type="text" ng-model="email" <!-- Press ENTER and call myFunc --> />
</form>
</div>
Wrapping each input field in its own form tag allows ENTER to invoke submit on either form. If you use one form tag for both, you will have to include a submit button.
Does your HOSTS file have an entry for localhost
? Some other situations this error is seen in seem to have this as a problem resolution.
Make sure you have 127.0.0.1 localhost

You don't need pip
for installing Beautiful Soup - you can just download it and run python setup.py install
from the directory that you have unzipped BeautifulSoup in (assuming that you have added Python to your system PATH
- if you haven't and you don't want to you can run C:\Path\To\Python27\python "C:\Path\To\BeautifulSoup\setup.py" install
)
However, you really should install pip
- see How to install pip on Windows for how to do that best (via @MartijnPieters comment)
I implemented a max heap version of heapq and submitted it to PyPI. (Very slight change of heapq module CPython code.)
https://pypi.python.org/pypi/heapq_max/
https://github.com/he-zhe/heapq_max
Installation
pip install heapq_max
Usage
tl;dr: same as heapq module except adding ‘_max’ to all functions.
heap_max = [] # creates an empty heap
heappush_max(heap_max, item) # pushes a new item on the heap
item = heappop_max(heap_max) # pops the largest item from the heap
item = heap_max[0] # largest item on the heap without popping it
heapify_max(x) # transforms list into a heap, in-place, in linear time
item = heapreplace_max(heap_max, item) # pops and returns largest item, and
# adds new item; the heap size is unchanged
Assuming (!) the strings are of equal length, why not convert the strings to byte arrays and then XOR the bytes. The resultant byte arrays may be of different lengths too depending on your encoding (e.g. UTF8 will expand to different byte lengths for different characters).
You should be careful to specify the character encoding to ensure consistent/reliable string/byte conversion.
Add following rule to tr and it should work
float: left

That is htmlFor in JSX and class is className in JSX
Add a css reset to the top of your website style sheet, different browsers render some default margin and padding and perhaps external style sheets do something you are not aware of too, a css reset will just initialize a fresh palette so to speak:
html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, font, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, caption {
margin: 0;
padding: 0;
border: 0;
outline: 0;
font-size: 100%;
vertical-align: baseline;
background: transparent;
}
UPDATE: Use the Universal Selector Instead:
@Frank mentioned that you can use the Universal Selector: *
instead of listing all the elements, and this selector looks like it is cross browser compatible in all major browsers:
* {
margin: 0;
padding: 0;
border: 0;
outline: 0;
font-size: 100%;
vertical-align: baseline;
background: transparent;
}
One quick way of doing this is with the Python pandas library (version 0.15 or above works best). This will handle creating the columns for you - although obviously the choices it makes for data types might not be what you want. If it doesn't quite do what you want you can always use the 'create table' code generated as a template.
Here's a simple example:
import pandas as pd
df = pd.read_csv('mypath.csv')
df.columns = [c.lower() for c in df.columns] #postgres doesn't like capitals or spaces
from sqlalchemy import create_engine
engine = create_engine('postgresql://username:password@localhost:5432/dbname')
df.to_sql("my_table_name", engine)
And here's some code that shows you how to set various options:
# Set it so the raw sql output is logged
import logging
logging.basicConfig()
logging.getLogger('sqlalchemy.engine').setLevel(logging.INFO)
df.to_sql("my_table_name2",
engine,
if_exists="append", #options are ‘fail’, ‘replace’, ‘append’, default ‘fail’
index=False, #Do not output the index of the dataframe
dtype={'col1': sqlalchemy.types.NUMERIC,
'col2': sqlalchemy.types.String}) #Datatypes should be [sqlalchemy types][1]
Give an ID to uniquely identify the button, lets say myBtn
// when DOM is ready
$(document).ready(function () {
// Attach Button click event listener
$("#myBtn").click(function(){
// show Modal
$('#myModal').modal('show');
});
});
Something like this:
Dim rng As Range
Dim row As Range
Dim cell As Range
Set rng = Range("A1:C2")
For Each row In rng.Rows
For Each cell in row.Cells
'Do Something
Next cell
Next row
This one-liner works for me:
WebRequest.DefaultWebProxy.Credentials = CredentialCache.DefaultNetworkCredentials;
CredentialCache.DefaultNetWorkCredentials
is the proxy settings set in Internet Explorer.
WebRequest.DefaultWebProxy.Credentials
is used for all internet connectivity in the application.
Try This url with valid userid and access token:
https://graph.facebook.com/{userid}/photos?limit=20&access_token={access_token}
For OSX, you can go to your user's $HOME
(probably /Users/yourname/) and, if it doesn't already exist, create an .npmrc
file (a file that npm uses for user configuration), and create a directory for your npm packages to be installed in (e.g., /Users/yourname/npm). In that .npmrc file, set "prefix" to your new npm directory, which will be where "globally" installed npm packages will be installed; these "global" packages will, obviously, be available only to your user account.
In .npmrc:
prefix=${HOME}/npm
Then run this command from the command line:
npm config ls -l
It should give output on both your own local configuration and the global npm configuration, and you should see your local prefix configuration reflected, probably near the top of the long list of output.
For security, I recommend this approach to configuring your user account's npm behavior over chown-ing your /usr/local
folders, which I've seen recommended elsewhere.
OK so, it isn't css hack, but out of frustration for not being able to find ways to target ie8 from css, and due to policy of not having ie specific css files, I had to do following, which I assume someone else might find useful:

$(results).css({
'left':'23px',
'top':'-253px'

I implemented Marcus Ekwall's solution but was able to remove a few things to make it simpler and it still works. Maybe 2017 version of html/css?

<h2>What is Lorem Ipsum?</h2>
<p><strong>Lorem Ipsum</strong> is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen
book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with
desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
</div>
css:
#content {
text-align: left;
width: 75%;
margin: auto;
position: relative;
}
#bg {
position: absolute;
top: 0;
bottom: 0;

If you are using JQuery Google map plug-in then below code will work for you -
var markers = $('#map_canvas').gmap('get','markers');
You can also achieve similar results by using 'query' and @:
eg:
df = pd.DataFrame({'A': [1, 2, 3], 'B': ['a', 'b', 'f']})
df = pd.DataFrame({'A' : [5,6,3,4], 'B' : [1,2,3, 5]})
list_of_values = [3,6]
result= df.query("A in @list_of_values")
result
A B
1 6 2
2 3 3
Not for entire application or particular class.
CurrentUICulture and CurrentCulture are settable per thread as discussed here Is there a way of setting culture for a whole application? All current threads and new threads?. You can't change InvariantCulture
at all.
Sample code to change cultures for current thread:
CultureInfo ci = new CultureInfo(theCultureString);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;
For class you can set/restore culture inside critical methods, but it would be significantly safe to use appropriate overrides for most formatting related methods that take culture as one of arguments:
(3.3).ToString(new CultureInfo("fr-FR"))
I know this is old, but here's the solution I came up with when I didn't like the ones I found.
-Loop through the array (Variant) adding each element and some divider to a string, unless it matches the one you want to remove -Then split the string on the divider
tmpString=""
For Each arrElem in GlobalArray
If CStr(arrElem) = "removeThis" Then
GoTo SkipElem
Else
tmpString =tmpString & ":-:" & CStr(arrElem)
End If
SkipElem:
Next
GlobalArray = Split(tmpString, ":-:")
Obviously the use of strings creates some limitations, like needing to be sure of the information already in the array, and as-is this code makes the first array element blank, but it does what I need and with a little more work it could be more versatile.
In your app.config
, change your appsetting to:
<applicationSettings>
<WpfApplication1.Properties.Settings>
<setting name="appsetting" serializeAs="String">
<value>c:\testdata.xml</value>
</setting>
</WpfApplication1.Properties.Settings>
</applicationSettings>
Then, in the code-behind:
string xmlDataDirectory = WpfApplication1.Properties.Settings.Default.appsetting.ToString()
In case you want to apply common functions such as sum or mean, you should use rowSums
or rowMeans
since they're faster than apply(data, 1, sum)
approach. Otherwise, stick with apply(data, 1, fun)
. You can pass additional arguments after FUN argument (as Dirk already suggested):
set.seed(1)
m <- matrix(round(runif(20, 1, 5)), ncol=4)
diag(m) <- NA
m
[,1] [,2] [,3] [,4]
[1,] NA 5 2 3
[2,] 2 NA 2 4
[3,] 3 4 NA 5
[4,] 5 4 3 NA
[5,] 2 1 4 4
Then you can do something like this:
apply(m, 1, quantile, probs=c(.25,.5, .75), na.rm=TRUE)
[,1] [,2] [,3] [,4] [,5]
25% 2.5 2 3.5 3.5 1.75
50% 3.0 2 4.0 4.0 3.00
75% 4.0 3 4.5 4.5 4.00
if your are using server, there's "public network IP" and "internal network IP". Use the "internal network IP" in your file /etc/hosts and "public network IP" in your code. if you use "public network IP" in your file /etc/hosts then you will get this error.
elem.offsetWdith VS ele.scrollWidth This work for me! https://jsfiddle.net/gustavojuan/210to9p1/
$(function() {
$('.endtext').each(function(index, elem) {
debugger;
if(elem.offsetWidth !== elem.scrollWidth){
$(this).css({color: '#FF0000'})
}
});
});
You can simply use padding-left:60% (for ex) to align your content to right and simultaneously wrap the content in responsive container (I required navbar in my case) to ensure it works in all examples.
w.female.replace(to_replace=dict(female=1, male=0), inplace=True)
This is the way I did it:
I just put
Intent intent = new Intent(Main.this, SOMECLASSNAME.class);
Main.this.startActivityForResult(intent, 0);
inside of the method that opens an activity, then inside of the method of SOMECLASSNAME that is designed to close the app I put:
setResult(0);
finish();
And I put the following in my Main class:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == 0) {
finish();
}
}
You should not do it for UPDATE
and DELETE
, as if there is impact on performance, it is not a positive one.
For INSERT
there might be situations where your INSERT
will raise an exception (UNIQUE CONSTRAINT
violation etc), in which case you might want to prevent it with the IF EXISTS
and handle it more gracefully.
Here's a function I wrote which works similarly to the Unix time

$start = Get-Date
try {
if ( -not $quiet ) {
iex $command | Write-Host
} else {
iex $command > $null
}
} finally {
$(Get-Date) - $start
}

Built upon rsplak's answer. It uses jQuery's newer .on() instead of the deprecated .bind(). In addition to input, it will also work for select and other html elements. It will also disable the submit button if one of the fields becomes blank again.
var fields = "#user_input, #pass_input, #v_pass_input, #email";
$(fields).on('change', function() {
if (allFilled()) {
$('#register').removeAttr('disabled');
} else {
$('#register').attr('disabled', 'disabled');
}
});
function allFilled() {
var filled = true;
$(fields).each(function() {
if ($(this).val() == '') {
filled = false;
}
});
return filled;
}
Demo: JSFiddle
another way is, you assign a column value for a given row based on the index position of a row, the index position always starts with zero, and the last index position is the length of the dataframe:
df["COL_NAME"].iloc[0]=x
Android Q broke most of these for me. Here's a new one that seems to be working (at least on Android Q).
adb shell "dumpsys activity activities | grep mResumedActivity"
Output looks like:
mResumedActivity: ActivityRecord{7f6df99 u0 com.sample.app/.feature.SampleActivity t92}
Edit: Works on Android R for me as well
$.ajax({
url: 'http://url.of.my.server/submit',
dataType: "jsonp",
jsonp: 'callback',
jsonpCallback: 'jsonp_callback'
});
jsonp is the querystring parameter name that is defined to be acceptable by the server while the jsonpCallback is the javascript function name to be executed at the client.
When you use such url:
url: 'http://url.of.my.server/submit?callback=?'
the question mark ? at the end instructs jQuery to generate a random function while the predfined behavior of the autogenerated function will just invoke the callback -the sucess function in this case- passing the json data as a parameter.
$.ajax({
url: 'http://url.of.my.server/submit?callback=?',
success: function (data, status) {
mySurvey.closePopup();
},
error: function (xOptions, textStatus) {
mySurvey.closePopup();
}
});
The same goes here if you are using $.getJSON with ? placeholder it will generate a random function while the predfined behavior of the autogenerated function will just invoke the callback:
$.getJSON('http://url.of.my.server/submit?callback=?',function(data){
//process data here
});

getParentFragmentManager().setFragmentResultListener
is the 2020 way of doing this. Your only limitation is to use a bundle to pass the data. Check out the docs for more info and examples.
Some other ways
getActivity()
and cast it to the shared activity between your fragments, then use it as a bridge to pass the data. This solution is highly not recommended because of the cupelling it requires between the activity and the fragments, but it used to be the popular way of doing this back in the KitKat days...FragmentManager
is that it's not limited to Bundles. The downside, however, is that you may run into edge cases bugs where you mess up the activity life cycle and get exceptions like IllegalStateException
when the fragment manager is in the middle of saving state or the activity were destroyed. Also, it does not support cross-processing communication.This should work:
$('.myClass, .myOtherClass').removeClass('theclass');
You must add the multiple selectors all in the first argument to $(), otherwise you are giving jQuery a context in which to search, which is not what you want.
It's the same as you would do in CSS.
There is a lot of confusion on this topic because there are so many different ways to do it.
Here are the appropriate types used in the following screen shots:
private route: ActivatedRoute
private router: Router
1) Required Routing Parameters:
2) Route Optional Parameters:
3) Route Query Parameters:
4) You can use a service to pass data from one component to another without using route parameters at all.
For an example see: https://blogs.msmvps.com/deborahk/build-a-simple-angular-service-to-share-data/

would allow appending text into the File if it exists. println(...)
on your PrintWriter, writing your new text into the file.close()
of the PrintWriter should be in the try's finally block.e.g.,
PrintWriter pw = null;
try {
File file = new File("fubars.txt");
FileWriter fw = new FileWriter(file, true);
pw = new PrintWriter(fw);
pw.println("Fubars rule!");
} catch (IOException e) {
e.printStackTrace();

if (pw != null) {
pw.close();

A nice approach would be to start up your processes and services running them in the background and use the wait [n ...]
command at the end of your script. In bash, the wait command forces the current process to:
Wait for each specified process and return its termination status. If n is not given, all currently active child processes are waited for, and the return status is zero.
I got this idea from Sébastien Pujadas' start script for his elk build.
Taking from the original question, your start-all.sh would look something like this...
#!/usr/bin/env bash
/etc/init.d/hadoop-hdfs-namenode start &
/etc/init.d/hadoop-hdfs-datanode start &
/etc/init.d/hadoop-hdfs-secondarynamenode start &
/etc/init.d/hadoop-0.20-mapreduce-tasktracker start &
sudo -u hdfs hadoop fs -chmod 777 /
/etc/init.d/hadoop-0.20-mapreduce-jobtracker start &
wait
On Windows they get installed to separate folders, "C:\python26" and "C:\python31", but the executables have the same "python.exe" name.
I created another "C:\python" folder that contains "python.bat" and "python3.bat" that serve as wrappers to "python26" and "python31" respectively, and added "C:\python" to the PATH
environment variable.
This allows me to type python
or python3
in my .bat Python wrappers to start the one I desire.
On Linux, you can use the #!
trick to specify which version you want a script to use.
Found a very easy way to do this.
Paste following php script in box. In php script set API_ACCESS_KEY, set device ids separated by coma.
Press F9 or click Run.
Have fun ;)
<?php
// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'YOUR-API-ACCESS-KEY-GOES-HERE' );
$registrationIds = array("YOUR DEVICE IDS WILL GO HERE" );
// prep the bundle
$msg = array
(
'message' => 'here is a message. message',
'title' => 'This is a title. title',
'subtitle' => 'This is a subtitle. subtitle',
'tickerText' => 'Ticker text here...Ticker text here...Ticker text here',
'vibrate' => 1,
'sound' => 1
);
$fields = array
(
'registration_ids' => $registrationIds,
'data' => $msg
);
$headers = array
(
'Authorization: key=' . API_ACCESS_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );

For FCM, google url would be: https://fcm.googleapis.com/fcm/send
For FCM v1 google url would be: https://fcm.googleapis.com/v1/projects/YOUR_GOOGLE_CONSOLE_PROJECT_ID/messages:send
Note: While creating API Access Key on google developer console, you have to use 0.0.0.0/0 as ip address. (For testing purpose).
In case of receiving invalid Registration response from GCM server, please cross check the validity of your device token. You may check the validity of your device token using following url:
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=YOUR_DEVICE_TOKEN
Some response codes:
Following is the description of some response codes you may receive from server.
{ "message_id": "XXXX" } - success
{ "message_id": "XXXX", "registration_id": "XXXX" } - success, device registration id has been changed mainly due to app re-install
{ "error": "Unavailable" } - Server not available, resend the message
{ "error": "InvalidRegistration" } - Invalid device registration Id
{ "error": "NotRegistered"} - Application was uninstalled from the device

Confirmed working on:
No, there is no way (that I know of), of doing that in Java.
Basically you'll have to transform each entry from String to Integer.
What you're looking for could be achieved in a more functional language, where you could pass a transformation function and apply it to every element of the list... but such is not possible (it would still apply to every element in the list).
Overkill:
You can, however use a Function from Google Guava (http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/base/Function.html) to simulate a more functional approach, if that is what you're looking for.
If you're worried about iterating over the list twice, then instead of split use a Tokenizer and transform each integer token to Integer before adding to the list.
You may also insert the element using the slice indexing in the list. For example:
>>> a = [1, 2, 4]
>>> insert_at = 2 # Index at which you want to insert item
>>> b = a[:] # Created copy of list "a" as "b".
# Skip this step if you are ok with modifying the original list
>>> b[insert_at:insert_at] = [3] # Insert "3" within "b"
>>> b
[1, 2, 3, 4]
For inserting multiple elements together at a given index, all you need to do is to use a list
of multiple elements that you want to insert. For example:
>>> a = [1, 2, 4]
>>> insert_at = 2 # Index starting from which multiple elements will be inserted
# List of elements that you want to insert together at "index_at" (above) position
>>> insert_elements = [3, 5, 6]
>>> a[insert_at:insert_at] = insert_elements
>>> a # [3, 5, 6] are inserted together in `a` starting at index "2"
[1, 2, 3, 5, 6, 4]
To know more about slice indexing, you can refer: Understanding slice notation.
Note: In Python 3.x, difference of performance between slice indexing and list.index(...)
is significantly reduced and both are almost equivalent. However, in Python 2.x, this difference is quite noticeable. I have shared performance comparisons later in this answer.
Alternative using list comprehension (but very slow in terms of performance):
As an alternative, it can be achieved using list comprehension with enumerate
too. (But please don't do it this way. It is just for illustration):
>>> a = [1, 2, 4]
>>> insert_at = 2
>>> b = [y for i, x in enumerate(a) for y in ((3, x) if i == insert_at else (x, ))]
>>> b
[1, 2, 3, 4]

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut
or via an instance e.g. shape.lolwut
but be careful while setting it as it will set an instance level attribute not class attribute
class Shape(object):
lolwut = 1
shape = Shape()
print Shape.lolwut, # 1
print shape.lolwut, # 1
# setting shape.lolwut would not change class attribute lolwut
# but will create it in the instance
shape.lolwut = 2
print Shape.lolwut, # 1
print shape.lolwut, # 2
# to change class attribute access it via class
Shape.lolwut = 3
print Shape.lolwut, # 3
print shape.lolwut # 2
output:
1 1 1 2 3 2
Somebody may expect output to be 1 1 2 2 3 3
but it would be incorrect
The Javascript interpreter natively stores objects in a hash table. If you're worried about contamination from the prototype chain, you can always do something like this:
// Simple ECMA5 hash table
Hash = function(oSource){
for(sKey in oSource) if(Object.prototype.hasOwnProperty.call(oSource, sKey)) this[sKey] = oSource[sKey];
};
Hash.prototype = Object.create(null);
var oHash = new Hash({foo: 'bar'});
oHash.foo === 'bar'; // true
oHash['foo'] === 'bar'; // true
oHash['meow'] = 'another prop'; // true
oHash.hasOwnProperty === undefined; // true
Object.keys(oHash); // ['foo', 'meow']
oHash instanceof Hash; // true
I am using Bootstrap CSS, JS and Fonts in my application. I created a folder called asset
in root directory of the app and place all these folder inside it. Then in server file added following line:
app.use("/asset",express.static("asset"));
This line enables me to load the files that are in the asset
directory from the /asset
path prefix like: http://localhost:3000/asset/css/bootstrap.min.css
.
Now in the views I can simply include CSS and JS like below:
<link href="/asset/css/bootstrap.min.css" rel="stylesheet">
You can get value by using id for that element in onclick function
function dosomething(){
var buttonValue = document.getElementById('buttonId').value;
}
Chart.js is quite useful, supporting numerous other types of charts as well.
It can be used both with jQuery and without.
A token is a piece of data created by server, and contains information to identify a particular user and token validity. The token will contain the user's information, as well as a special token code that user can pass to the server with every method that supports authentication, instead of passing a username and password directly.
Token-based authentication is a security technique that authenticates the users who attempt to log in to a server, a network, or some other secure system, using a security token provided by the server.
An authentication is successful if a user can prove to a server that he or she is a valid user by passing a security token. The service validates the security token and processes the user request.
After the token is validated by the service, it is used to establish security context for the client, so the service can make authorization decisions or audit activity for successive user requests.
This is what the res.locals object is for. Setting variables directly on the request object is not supported or documented. res.locals is guaranteed to hold state over the life of a request.
An object that contains response local variables scoped to the request, and therefore available only to the view(s) rendered during that request / response cycle (if any). Otherwise, this property is identical to app.locals.
This property is useful for exposing request-level information such as the request path name, authenticated user, user settings, and so on.
app.use(function(req, res, next) {
res.locals.user = req.user;
res.locals.authenticated = !req.user.anonymous;
next();
});
To retrieve the variable in the next middleware:
app.use(function(req, res, next) {
if (res.locals.authenticated) {
console.log(res.locals.user.id);
}
next();
});
Create the column:
ALTER TABLE yourtable ADD COLUMN combined VARCHAR(50);
Update the current values:
UPDATE yourtable SET combined = CONCAT(zipcode, ' - ', city, ', ', state);
Update all future values automatically:
CREATE TRIGGER insert_trigger
BEFORE INSERT ON yourtable
FOR EACH ROW
SET new.combined = CONCAT(new.zipcode, ' - ', new.city, ', ', new.state);
CREATE TRIGGER update_trigger
BEFORE UPDATE ON yourtable
FOR EACH ROW
SET new.combined = CONCAT(new.zipcode, ' - ', new.city, ', ', new.state);
Use the -p flag and add /udp
suffix to the port number.
-p 53160:53160/udp
Full command
sudo docker run -p 53160:53160 \
-p 53160:53160/udp -p 58846:58846 \
-p 8112:8112 -t -i aostanin/deluge /start.sh
If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.
You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile
(EXPOSE does not publish the port):
EXPOSE 8285/udp
Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)
The simplest way to do this is:
git tag v1.0.0 f4ba1fc
git push origin --tags
with f4ba1fc
being the beginning of the hash of the commit you want to tag and v1.0.0
being the version you want to tag.
I think the word you're looking for is "overloading". There isn't any method overloading in Python. You can however use default arguments, as follows.
def stackoverflow(self, i=None):
if i != None:
print 'second method', i
else:
print 'first method'
When you pass it an argument, it will follow the logic of the first condition and execute the first print statement. When you pass it no arguments, it will go into the else
condition and execute the second print statement.
Using Jquery
Rather than creating temp variables it can be written in a continuous flow pattern as follows:
$('</form>', { action: url, method: 'POST' }).append(
$('<input>', {type: 'hidden', id: 'id_field_1', name: 'name_field_1', value: val_field_1}),
$('<input>', {type: 'hidden', id: 'id_field_2', name: 'name_field_2', value: val_field_2}),
).appendTo('body').submit();
Assuming that both data1()
and data2()
are in the same class, then another alternative is to make data1()
static.
private static void data1()
{
}
private static void data2()
{
data1();
}
Here's an approach I use for tighter control over how things are drawn
var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
var scale = 1;
var xO = 0;
var yO = 0;
draw();
function draw(){
// Clear screen
ctx.clearRect(0, 0, canvas.offsetWidth, canvas.offsetHeight);
// Original coordinates
const xData = 50, yData = 50, wData = 100, hData = 100;
// Transformed coordinates
const x = xData * scale + xO,
y = yData * scale + yO,
w = wData * scale,
h = hData * scale;
// Draw transformed positions
ctx.fillStyle = "black";
ctx.fillRect(x,y,w,h);
}
canvas.onwheel = function (e){
e.preventDefault();
const r = canvas.getBoundingClientRect(),
xNode = e.pageX - r.left,
yNode = e.pageY - r.top;
const newScale = scale * Math.exp(-Math.sign(e.deltaY) * 0.2),
scaleFactor = newScale/scale;
xO = xNode - scaleFactor * (xNode - xO);
yO = yNode - scaleFactor * (yNode - yO);
scale = newScale;
draw();
}

Use np.select
if you have multiple conditions to be checked from the dataframe and output a specific choice in a different column
conditions=[(condition1),(condition2)]
choices=["choice1","chocie2"]
df["new column"]=np.select=(condtion,choice,default=)
Note: No of conditions and no of choices should match, repeat text in choice if for two different conditions you have same choices
Thymeleaf has an equivalent to <c:choose>
and <c:when>
: the th:switch
and th:case
attributes introduced in Thymeleaf 2.0.
They work as you'd expect, using *
for the default case:
<div th:switch="${user.role}">
<p th:case="'admin'">User is an administrator</p>
<p th:case="#{roles.manager}">User is a manager</p>
<p th:case="*">User is some other thing</p>
</div>
See this for a quick explanation of syntax (or the Thymeleaf tutorials).
Disclaimer: As required by StackOverflow rules, I'm the author of Thymeleaf.
I have just faced with similar issue building LLVM 3.7 version. first check whether you have installed the required library on your system:
$locate libstdc++.so.6.*
Then add the found location to your $LD_LIBRARY_PATH environment variable.
No, the only thing that needs to be modified for an Anaconda environment is the PATH (so that it gets the right Python from the environment bin/
directory, or Scripts\
on Windows).
The way Anaconda environments work is that they hard link everything that is installed into the environment. For all intents and purposes, this means that each environment is a completely separate installation of Python and all the packages. By using hard links, this is done efficiently. Thus, there's no need to mess with PYTHONPATH because the Python binary in the environment already searches the site-packages in the environment, and the lib of the environment, and so on.
Example:
driver.execute_script("arguments[0].scrollIntoView();", driver.find_element_by_css_selector(.your_css_selector))
This one always works for me for any type of selectors. There is also the Actions class, but for this case, it is not so reliable.

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID
before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.
You have to nest the requests:
$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE" , function(name){ obj = name; // sID is only now available! sID = obj.id; console.log(sID); });
name.id
is sufficient unless you really need the other variables outside the function.$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE" , function(name){ // We don't need sID or obj here - name.id is sufficient console.log(name.id); doSecondRequest(name.id); }); /// TODO Choose a better name function doSecondRequest(sID) { $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){ console.log(stats); }); }

I do not know if this is a bug from Google or an intended behavior but I (at least momentarily) solved it by changing compileSdkVersion and targetSdkVersion back to 26 in Gradle...
If you still see permission denied
after verifying the permissions of the parent folders, it may be SELinux restricting access.
To check if SELinux is running:
# getenforce
To disable SELinux until next reboot:
# setenforce Permissive
Restart Nginx and see if the problem persists. To allow nginx to serve your www directory (make sure you turn SELinux back on before testing this. i.e, setenforce Enforcing
)
# chcon -Rt httpd_sys_content_t /path/to/www

When Python2.x sees a == b
, it tries the following.
type(b)
is a new-style class, and type(b)
is a subclass of type(a)
, and type(b)
has overridden __eq__
, then the result is b.__eq__(a)
.type(a)
has overridden __eq__
(that is, type(a).__eq__
isn't object.__eq__
), then the result is a.__eq__(b)
.type(b)
has overridden __eq__
, then the result is b.__eq__(a)
.__cmp__
. If it exists, the objects are equal iff it returns zero
.object.__eq__(a, b)
, which is True
iff a
and b
are the same object.If any of the special methods return NotImplemented
, Python acts as though the method didn't exist.
Note that last step carefully: if neither a
nor b
overloads ==
, then a == b
is the same as a is b
.
@bku_drytt's solution didn't do it for me.
I solved it by additionally changing every occurence of 14.0

to v120
manually in the .vcxproj files.
Then it compiled!

double[][]
are called jagged arrays , The inner dimensions aren’t specified in the declaration. Unlike a rectangular array, each inner array can be an arbitrary length. Each inner array is implicitly initialized to null rather than an empty array. Each inner array must be created manually: Reference [C# 4.0 in nutshell The definitive Reference]
for (int i = 0; i < matrix.Length; i++)
{
matrix[i] = new int [3]; // Create inner array
for (int j = 0; j < matrix[i].Length; j++)
matrix[i][j] = i * 3 + j;
}
double[,]
are called rectangular arrays
, which are declared using commas to separate each dimension. The following piece of code declares a rectangular 3-by-3 two-dimensional array, initializing it with numbers from 0 to 8:
int [,] matrix = new int [3, 3];
for (int i = 0; i < matrix.GetLength(0); i++)
for (int j = 0; j < matrix.GetLength(1); j++)
matrix [i, j] = i * 3 + j;
This might be useful for someone.
Numpy's histogram function returns the edges of each bin, rather than the value of the bin. This makes sense for floating-point numbers, which can lie within an interval, but may not be the desired result when dealing with discrete values or integers (0, 1, 2, etc). In particular, the length of bins returned from np.histogram is not equal to the length of the counts / density.
To get around this, I used np.digitize to quantize the input, and count the fraction of counts for each bin. You could easily edit to get the integer number of counts.
def compute_PMF(data):
import numpy as np
from collections import Counter
_, bins = np.histogram(data, bins='auto', range=(data.min(), data.max()), density=False)
h = Counter(np.digitize(data,bins) - 1)
weights = np.asarray(list(h.values()))
weights = weights / weights.sum()
values = np.asarray(list(h.keys()))
return weights, values

On my machine mysqld service stopped that's why it was giving me the same problem.
1:- Go to terminal and type
sudo service mysqld restart
This will restart the mysqld service and create a new sock file on the required location.
Actually, you can save you picture at any place. If you want to save in a public space, so any other application can access, use this code:
storageDir = new File(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES
),
getAlbumName()
);
The picture doesn't go to the album. To do this, you need to call a scan:
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}

As far as I know, there is no such a thing as iOS emulator on windows or linux, there are only some gameengines that enable you to compile same code for both iOS and windows or linux and there is a toolchain to compile iOS application using linux. none of them are realy emulator/simulator things. and to use that toolchain you need a jailbreaked iOS device to test binary file created using toolchain. I mean linux itself can't run the binary created itself. and by the way even in mac simulator is just an intermediate program which runs mac-compiled binary, since if you change compiling for iOS from simulator or the other way, all the files are rebuild. and also there are some real differences, like iOS is a case-sensitive operation while simulator is not.
so the best solution is to buy an iOS device yourself.
it simply means sorting the view or table by 1st column of query's result.
I use a generic query I call "dump" (why? I don't know) that looks like this:
SET NEWPAGE NONE
SET PAGESIZE 0
SET SPACE 0
SET LINESIZE 16000
SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET TERMOUT OFF
SET TRIMOUT ON
SET TRIMSPOOL ON
SET COLSEP |
spool &1..txt
@@&1
spool off
exit
I then call SQL*Plus passing the actual SQL script I want to run as an argument:
sqlplus -S user/password@database @dump.sql my_real_query.sql
The result is written to a file
my_real_query.sql.txt
.
The first way
Needs root
Use kill
:
adb shell ps
=> Will list all running processes on the device and their process ids
adb shell kill <PID>
=> Instead of <PID>
use process id of your application
The second way
In Eclipse open DDMS
perspective.
In Devices
view you will find all running processes.
Choose the process and click on Stop
.
The third way
It will kill only background process of an application.
adb shell am kill [options] <PACKAGE>
=> Kill all processes associated with (the app's package name). This command kills only processes that are safe to kill and that will not impact the user experience.
Options are:
--user | all | current: Specify user whose processes to kill; all users if not specified.
The fourth way
Needs root
adb shell pm disable <PACKAGE>
=> Disable the given package or component (written as "package/class").
The fifth way
Note that run-as is only supported for apps that are signed with debug keys.
run-as <package-name> kill <pid>
The sixth way
Introduced in Honeycomb
adb shell am force-stop <PACKAGE>
=> Force stop everything associated with (the app's package name).
P.S.: I know that the sixth method didn't work for you, but I think that it's important to add this method to the list, so everyone will know it.
You have to pass a function to expect
. Like this:
expect(model.get.bind(model, 'z')).to.throw('Property does not exist in model schema.');
expect(model.get.bind(model, 'z')).to.throw(new Error('Property does not exist in model schema.'));
The way you are doing it, you are passing to expect
the result of calling model.get('z')
. But to test whether something is thrown, you have to pass a function to expect
, which expect
will call itself. The bind
method used above creates a new function which when called will call model.get
with this
set to the value of model
and the first argument set to 'z'
.
A good explanation of bind
can be found here.
That way you haven't installed pip, you installed just the easy_install
i.e. setuptools
.
First you should remove all the packages you installed with easy_install
using (see uninstall):
easy_install -m PackageName
This includes pip
if you installed it using easy_install pip
.
After this you remove the setuptools
following the instructions from here:
If setuptools package is found in your global site-packages directory, you may safely remove the following file/directory:
setuptools-*.egg
If setuptools is installed in some other location such as the user site directory (eg: ~/.local, ~/Library/Python or %APPDATA%), then you may safely remove the following files:
pkg_resources.py
easy_install.py
setuptools/
setuptools-*.egg-info/
I had a similar issue and found that it was much simpler to to get rid of the Excel files as soon as possible. As part of the first steps in my package I used Powershell to extract the data out of the Excel files into CSV files. My own Excel files were simple but here
Extract and convert all Excel worksheets into CSV files using PowerShell
is an excellent article by Tim Smith on extracting data from multiple Excel files and/or multiple sheets.
Once the Excel files have been converted to CSV the data import is much less complicated.
With Python 3.8 one can simply use f-string debugging feature:
>>> foo = dict()
>>> f'{foo=}'.split('=')[0]
'foo'

The user comments on the array_unique() documentation have many solutions to this. Here is one of them:
kenrbnsn at rbnsn dot com
27-Sep-2005 12:09Yet another Array_Unique for multi-demensioned arrays. I've only tested this on two-demensioned arrays, but it could probably be generalized for more, or made to use recursion.
This function uses the serialize, array_unique, and unserialize functions to do the work.
function multi_unique($array) { foreach ($array as $k=>$na) $new[$k] = serialize($na); $uniq = array_unique($new); foreach($uniq as $k=>$ser) $new1[$k] = unserialize($ser); return ($new1); }
This is from http://ca3.php.net/manual/en/function.array-unique.php#57202.
In .NET 5 / C# 8:
You can write the code marked as the answer as:
public static class StringExtensions
{
public static string TrimLastCharacters(this string str) => string.IsNullOrEmpty(str) ? str : str.TrimEnd(str[^1]);
}
However, as mentioned in the answer, this removes all occurrences of that last character. If you only want to remove the last character you should instead do:
public static string RemoveLastCharacter(this string str) => string.IsNullOrEmpty(str) ? str : str[..^1];
A quick explanation for the new stuff in C# 8:
The ^
is called the "index from end operator". The ..
is called the "range operator". ^1
is a shortcut for arr.length - 1
. You can get all items after the first character of an array with arr[1..]
or all items before the last with arr[..^1]
. These are just a few quick examples. For more information, see https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-8, "Indices and ranges" section.
Unfortunately, there is no fool-proof way of achieving this. A block will only expand to the height of its container if it is not floated. Floated blocks are considered outside of the document flow.
One way to do the following without using JavaScript is via a technique called Faux-Columns.
It basically involves applying a background-image
to the parent elements of the floated elements which makes you believe that the two elements are the same height.
More information available at:
I found a solution on the MSDN forums. The sample code below will remove all Click
events from button1
.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
button1.Click += button1_Click;
button1.Click += button1_Click2;
button2.Click += button2_Click;
}
private void button1_Click(object sender, EventArgs e) => MessageBox.Show("Hello");
private void button1_Click2(object sender, EventArgs e) => MessageBox.Show("World");
private void button2_Click(object sender, EventArgs e) => RemoveClickEvent(button1);
private void RemoveClickEvent(Button b)
{
FieldInfo f1 = typeof(Control).GetField("EventClick",
BindingFlags.Static | BindingFlags.NonPublic);
object obj = f1.GetValue(b);
PropertyInfo pi = b.GetType().GetProperty("Events",
BindingFlags.NonPublic | BindingFlags.Instance);
EventHandlerList list = (EventHandlerList)pi.GetValue(b, null);
list.RemoveHandler(obj, list[obj]);
}
}
I haven't used Cassandra, but I have used MongoDB and think it's awesome.
If you're after simple setup, this is it: You simply untar MongoDB and run the mongod daemon and that's it ... it's running.
Obviously that's only a starter, but to get you started it's easy.
With this code you can obtain any controller:
var controller = DependencyResolver.Current.GetService<ControllerB>();
controller.ControllerContext = new ControllerContext(this.Request.RequestContext,
controller);
Check the Initial Catalog parameter in your connection string. It may be that your code is looking in the wrong database for the Projects object.
For example, if you have database syncing setup in such a way that only a subset of the master-database's tables are transferred, you can encounter this error if Linq to SQL is expecting all tables to be in the database pointed to by the connection string.
Instead of only using the path to your script in the task scheduler, you should start PowerShell with your script in the task scheduler, e.g.
C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe -NoLogo -NonInteractive -File "C:\Path\To\Your\PS1File.ps1"
See powershell /?
for an explanation of those switches.
If you still get problems you should read this question.
Whatever happened to my beloved readable Python language? :-)
Seriously, just make it a function:
def addInRange(val, add, minval, maxval):
newval = val + add
if newval < minval: return minval
if newval > maxval: return maxval
return newval
then just call it with something like:
val = addInRange(val, 7, 0, 42)
Or a simpler, more flexible, solution where you do the calculation yourself:
def restrict(val, minval, maxval):
if val < minval: return minval
if val > maxval: return maxval
return val
x = restrict(x+10, 0, 42)
If you wanted to, you could even make the min/max a list so it looks more "mathematically pure":
x = restrict(val+7, [0, 42])
Update (20160519): Firebase just released a new feature called Firebase Storage. This allows you to upload images and other non-JSON data to a dedicated storage service. We highly recommend that you use this for storing images, instead of storing them as base64 encoded data in the JSON database.
You certainly can! Depending on how big your images are, you have a couple options:
1. For smaller images (under 10mb)
We have an example project that does that here: https://github.com/firebase/firepano
The general approach is to load the file locally (using FileReader) so you can then store it in Firebase just as you would any other data. Since images are binary files, you'll want to get the base64-encoded contents so you can store it as a string. Or even more convenient, you can store it as a data: url which is then ready to plop in as the src of an img tag (this is what the example does)!
2. For larger images
Firebase does have a 10mb (of utf8-encoded string data) limit. If your image is bigger, you'll have to break it into 10mb chunks. You're right though that Firebase is more optimized for small strings that change frequently rather than multi-megabyte strings. If you have lots of large static data, I'd definitely recommend S3 or a CDN instead.
I think I know what you are asking for. Here is what you can do.
first get the height of the person say h meters.
if you can calculate the height of the camera from ground (using height if the person i.e. h) and get angles A and B using gyroscope or something from android then you can calculate the height of the object using the above formula.
Isn't this what you were looking for???
let me know if you need any explanation.
Here is a simpler solution to list all files in a directory and to download it.
In your index.php file
<?php
$dir = "./";
$allFiles = scandir($dir);
$files = array_diff($allFiles, array('.', '..')); // To remove . and ..
foreach($files as $file){
echo "<a href='download.php?file=".$file."'>".$file."</a><br>";
}
The scandir() function list all files and directories inside the specified path. It works with both PHP 5 and PHP 7.
Now in the download.php
<?php
$filename = basename($_GET['file']);
// Specify file path.
$path = ''; // '/uplods/'
$download_file = $path.$filename;
if(!empty($filename)){
// Check file is exists on given path.
if(file_exists($download_file))
{
header('Content-Disposition: attachment; filename=' . $filename);
readfile($download_file);
exit;
}
else
{
echo 'File does not exists on given path';
}
}
DOUBLE columns are not the same as DECIMAL columns, and you will get in trouble if you use DOUBLE columns for financial data.
DOUBLE is actually just a double precision (64 bit instead of 32 bit) version of FLOAT. Floating point numbers are approximate representations of real numbers and they are not exact. In fact, simple numbers like 0.01 do not have an exact representation in FLOAT or DOUBLE types.
DECIMAL columns are exact representations, but they take up a lot more space for a much smaller range of possible numbers. To create a column capable of holding values from 0.0001 to 99.9999 like you asked you would need the following statement
CREATE TABLE your_table
(
your_column DECIMAL(6,4) NOT NULL
);
The column definition follows the format DECIMAL(M, D) where M is the maximum number of digits (the precision) and D is the number of digits to the right of the decimal point (the scale).
This means that the previous command creates a column that accepts values from -99.9999 to 99.9999. You may also create an UNSIGNED DECIMAL column, ranging from 0.0000 to 99.9999.
For more information on MySQL DECIMAL the official docs are always a great resource.
Bear in mind that all of this information is true for versions of MySQL 5.0.3 and greater. If you are using previous versions, you really should upgrade.

UPDATE:
Upon learning flex recently, there is a cleaner way (no tables and less css). Set the wrapper as display: flex;
and to center it's children give it the properties align-items: center;
for (vertical) and justify-content: center;
(horizontal) centering.
See this updated JS Fiddle
Strange that nobody suggested this before.. I always use tables to do this.
Simply make a wrapper have display: table
and center stuff inside it with text-align: center
for horizontal and vertical-align: middle
for vertical alignment.
<div class='wrapper'>
<i class='icon fa fa-bars'></i>
</div>
and some sass like this
.wrapper{
display: table;
i{
display: table-cell;
vertical-align: middle;
text-align: center;
}
}
or see this JS Fiddle

You can show float numbers
i.e.
$myNonFormatedFloat = 5678.9
$myGermanNumber = number_format($myNonFormatedFloat, 2, ',', '.'); // -> 5.678,90
$myAngloSaxonianNumber = number_format($myNonFormatedFloat, 2, '.', ','); // -> 5,678.90
Note that, the
1st argument is the float number you would like to format
2nd argument is the number of decimals
3rd argument is the character used to visually separate the decimals
4th argument is the character used to visually separate thousands
Try this
<script type="text/javascript">
function AddItem()
{
// Create an Option object
var opt = document.createElement("option");
// Assign text and value to Option object
opt.text = "New Value";
opt.value = "New Value";
// Add an Option object to Drop Down List Box
document.getElementById('<%=DropDownList.ClientID%>').options.add(opt);
}
<script />
The Value will append to the drop down list.
One issue could be that if either make, model, or [serial number] were null, values would never get returned. Because string concatenations with null values always result in null, and not in () with null will always return nothing. The remedy for this is to use an operator such as IsNull(make, '') + IsNull(Model, ''), etc.
Tried all of these and also the solutions using netsh, winhttp etc. Geek On Acid's answer helped me download packages from the server but none of these solutions worked for using the package I wanted to run (twitteR package).
The best solution is to use a software that let's you configure system-wide proxy.
FreeCap (free) and Proxifier (trial) worked perfectly for me at my company.
Please note that you need to remove proxy settings from your browser and any other apps that you have configured to use proxy as these tools provide system-wide proxy for all network traffic from your computer.
>>> from datetime import datetime
>>> a = datetime.now()
# wait a bit
>>> b = datetime.now()
>>> d = b - a # yields a timedelta object
>>> d.seconds
7
(7 will be whatever amount of time you waited a bit above)
I find datetime.datetime to be fairly useful, so if there's a complicated or awkward scenario that you've encountered, please let us know.
EDIT: Thanks to @WoLpH for pointing out that one is not always necessarily looking to refresh so frequently that the datetimes will be close together. By accounting for the days in the delta, you can handle longer timestamp discrepancies:
>>> a = datetime(2010, 12, 5)
>>> b = datetime(2010, 12, 7)
>>> d = b - a
>>> d.seconds
0
>>> d.days
2
>>> d.seconds + d.days * 86400

Unfortunately, no. You will have to cast each value individually.
Command line arguments are accessible via String[] args
parameter of main
method.
For first argument you can check args[0]
entire code would look like

}
Here is the pattern I've used:
.PHONY: test_py_utils
PY_UTILS_DIR = py_utils
test_py_utils:
cd $(PY_UTILS_DIR) && black .
cd $(PY_UTILS_DIR) && isort .
cd $(PY_UTILS_DIR) && mypy .
cd $(PY_UTILS_DIR) && pytest -sl .
cd $(PY_UTILS_DIR) && flake8 .
My motivations for this pattern are:
$(MAKE) -C some_dir all
&&
) because it is less readable, and I fear that I will make a typo when editing the make recipe..ONESHELL
special target because:
.ONESHELL
causes all lines of the recipe to be executed even if one of the earlier lines has failed with a nonzero exit status. Workarounds like calling set -e
are possible, but such workarounds would have to be implemented for every recipe in the makefile.if u have optgroup inside select, u got error in DOM.
I think a best way:
$("#select option:last").after($('<option value="1">my option</option>'));
I had this problem when I was trying to run commands through CLI.
It was a problem with system looking at the JRE folder i.e.
D:\Program Files\Java\jre8\bin
. If we look in there, there is no Tools.jar
, hence the error.
You need to find where the JDK
is, in my case: D:\Program Files\Java\jdk1.8.0_11
, and if you look in the lib
directory, you will see Tools.jar
.
What I did I created a new environment variable JAVA_HOME
:
And then you need to edit your PATH variable to include JAVA_HOME, i.e. %JAVA_HOME%/bin;
Re-open command prompt and should run.
I'm not sure if this approach has been taken but a work around i'm using is:
from multiprocessing import Pool
t = None
def run(n):
return t.f(n)
class Test(object):
def __init__(self, number):
self.number = number
def f(self, x):
print x * self.number
def pool(self):
pool = Pool(2)
pool.map(run, range(10))
if __name__ == '__main__':
t = Test(9)
t.pool()
pool = Pool(2)
pool.map(run, range(10))
Output should be:
0

18
27
36

72
81

Definitely use integer types for your money computations.
This cannot be emphasized enough since at first glance it might seem that a floating point type is adequate.
Here an example in python code:
>>> amount = float(100.00) # one hundred dollars
>>> print amount
100.0
>>> new_amount = amount + 1
>>> print new_amount
101.0
>>> print new_amount - amount
>>> 1.0
looks pretty normal.
Now try this again with 10^20
Zimbabwe dollars:
>>> amount = float(1e20)
>>> print amount
1e+20
>>> new_amount = amount + 1
>>> print new_amount
1e+20
>>> print new_amount-amount
0.0
As you can see, the dollar disappeared.
If you use the integer type, it works fine:
>>> amount = int(1e20)
>>> print amount
100000000000000000000
>>> new_amount = amount + 1
>>> print new_amount
100000000000000000001
>>> print new_amount - amount

We are using git-repo to manage our multiple GIT repositories. There is also a Jenkins Repo plugin that allows to checkout all or part of the repositories managed by git-repo to the same Jenkins job workspace.
You would need to create your own dropdown using hidden divs and a hidden input element to record which option was "selected". My guess is that @Jan Hancic's link he posted is probably what you're looking for.

I found Code Rocket to be very useful - http://www.getcoderocket.com/
From their website: "Code Rocket is an innovative tool that reveals the inner workings of C#, ... and C/C++ code, for Visual Studio...

Things to note, the title, author and date fields are declared before \begin{document}
. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn
in the document class.
This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}
. Here's a more detailed article on \LaTeX
font sizes:
https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont
To italicize you can use {\it First Name}
or \textit{First Name}
.
Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.
No need for any Java or Kotlin code to make it a clickable link, now you just need to follow given below code. And you can also link text color change by using textColorLink.
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:autoLink="web"
android:textColorLink="@color/white"/>
It's because you're missing position:relative;
on #contentframe
<div id="contentframe" style="position:relative; top: 160px; left: 0px;">
position:absolute;
positions itself against the closest ancestor that has a position
that is not static
. Since the default is static
that is what was causing your issue.
var x = $('#container')[0].outerHTML;
Just in case if you are having issues with the code, try putting getSupportActionBar().setTitle(title)
inside onResume()
of your fragment instead of onCreateView(...)
i.e
In MainActivity.java :
public void setActionBarTitle(String title) {
getSupportActionBar().setTitle(title);
}
In Fragment:
@Override
public void onResume(){
super.onResume();
((MainActivity) getActivity()).setActionBarTitle("Your Title");
}
You have a numpy array of strings, not floats. This is what is meant by dtype('<U9')
-- a little endian encoded unicode string with up to 9 characters.
try:
return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))
However, you don't need numpy here at all. You can really just do:
return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)
Or if you're really set on using numpy.
return np.asarray(listOfEmb, dtype=float).mean()
Sometimes you inherit brittle code that is already expecting magic values in a lot of places. Everyone is correct, you should use NULL if possible. However, as a shortcut to make sure every reference to that value is the same, I like to put "constants" (for lack of a better name) in SQL in a scaler function and then call that function when I need the value. That way if I ever want to update them all to be something else, I can do so easily. Or if I want to change the default value moving forward, I only have one place to update it.
The following code creates the function and a table using it for the default DateTime value. Then inserts and select from the table without specifying the value for Modified. Then cleans up after itself. I hope this helps.

Here's what I've used for a two Column Layout of a <ul>
<ul class="list-group row">
<li class="list-group-item col-xs-6">Row1</li>
<li class="list-group-item col-xs-6">Row2</li>
<li class="list-group-item col-xs-6">Row3</li>
<li class="list-group-item col-xs-6">Row4</li>
<li class="list-group-item col-xs-6">Row5</li>
</ul>
This worked for me.
You can also get specific index using
curl -X GET "localhost:9200/<INDEX_NAME>"
e.g. curl -X GET "localhost:9200/twitter"
You may get output like:
{
"twitter": {
"aliases": {
},
"mappings": {
},
"settings": {
"index": {
"creation_date": "1540797250479",
"number_of_shards": "3",
"number_of_replicas": "2",
"uuid": "CHYecky8Q-ijsoJbpXP95w",
"version": {
"created": "6040299"
},
"provided_name": "twitter"
}
}
}

"UnicodeDecodeError: 'ascii' codec can't decode byte"
Cause of this error: input_string must be unicode but str was given
"TypeError: Decoding Unicode is not supported"
Cause of this error: trying to convert unicode input_string into unicode
So first check that your input_string is str
and convert to unicode if necessary:
if isinstance(input_string, str):
input_string = unicode(input_string, 'utf-8')
Secondly, the above just changes the type but does not remove non ascii characters. If you want to remove non-ascii characters:
if isinstance(input_string, str):
input_string = input_string.decode('ascii', 'ignore').encode('ascii') #note: this removes the character and encodes back to string.
elif isinstance(input_string, unicode):
input_string = input_string.encode('ascii', 'ignore')
If you are trying to delete/cut as suggested by @Pacific P. Regmi and if you are getting "Folder in use" which won't let you to delete/cut make sure to close all the android studio instances.
If the attribute you want to sort by is a property, then you can avoid importing operator.attrgetter
and use the property's fget
method instead.
For example, for a class Circle
with a property radius
we could sort a list of circles
by radii as follows:
result = sorted(circles, key=Circle.radius.fget)
This is not the most well-known feature but often saves me a line with the import.
From the documentation:
We can add to a list in many ways:
assert [1,2] + 3 + [4,5] + 6 == [1, 2, 3, 4, 5, 6]
assert [1,2].plus(3).plus([4,5]).plus(6) == [1, 2, 3, 4, 5, 6]
//equivalent method for +
def a= [1,2,3]; a += 4; a += [5,6]; assert a == [1,2,3,4,5,6]
assert [1, *[222, 333], 456] == [1, 222, 333, 456]
assert [ *[1,2,3] ] == [1,2,3]
assert [ 1, [2,3,[4,5],6], 7, [8,9] ].flatten() == [1, 2, 3, 4, 5, 6, 7, 8, 9]
def list= [1,2]
list.add(3) //alternative method name
list.addAll([5,4]) //alternative method name
assert list == [1,2,3,5,4]
list= [1,2]
list.add(1,3) //add 3 just before index 1
assert list == [1,3,2]
list.addAll(2,[5,4]) //add [5,4] just before index 2
assert list == [1,3,5,4,2]
list = ['a', 'b', 'z', 'e', 'u', 'v', 'g']
list[8] = 'x'
assert list == ['a', 'b', 'z', 'e', 'u', 'v', 'g', null, 'x']
You can also do:
def myNewList = myList << "fifth"
You should do the following:
1. /home/$USER/anaconda/bin/conda init zsh
(or /home/$USER/miniconda3/bin/conda init zsh
if you use miniconda)
2. source ~/.zshrc
(or just reopen terminal)
Why this answer is better than others?
~/.bash_profile
doesn't exist (my case, only ~/.bashrc
)~/.bash_profile
Method Overloading is known as Static Polymorphism and also Known as Compile Time Polymorphism or Static Binding because overloaded method calls get resolved at compile time by the compiler on the basis of the argument list and the reference on which we are calling the method.
And Method Overriding is known as Dynamic Polymorphism or simple Polymorphism or Runtime Method Dispatch or Dynamic Binding because overridden method call get resolved at runtime.
In order to understand why this is so let's take an example of Mammal
and Human
class
class Mammal {
public void speak() { System.out.println("ohlllalalalalalaoaoaoa"); }
}
class Human extends Mammal {
@Override
public void speak() { System.out.println("Hello"); }
public void speak(String language) {
if (language.equals("Hindi")) System.out.println("Namaste");
else System.out.println("Hello");
}
}
I have included output as well as bytecode of in below lines of code
Mammal anyMammal = new Mammal();
anyMammal.speak(); // Output - ohlllalalalalalaoaoaoa
// 10: invokevirtual #4 // Method org/programming/mitra/exercises/OverridingInternalExample$Mammal.speak:()V
Mammal humanMammal = new Human();
humanMammal.speak(); // Output - Hello
// 23: invokevirtual #4 // Method org/programming/mitra/exercises/OverridingInternalExample$Mammal.speak:()V
Human human = new Human();
human.speak(); // Output - Hello
// 36: invokevirtual #7 // Method org/programming/mitra/exercises/OverridingInternalExample$Human.speak:()V
human.speak("Hindi"); // Output - Namaste
// 42: invokevirtual #9 // Method org/programming/mitra/exercises/OverridingInternalExample$Human.speak:(Ljava/lang/String;)V
And by looking at above code we can see that the bytecodes of humanMammal.speak() , human.speak() and human.speak("Hindi") are totally different because the compiler is able to differentiate between them based on the argument list and class reference. And this is why Method Overloading is known as Static Polymorphism.
But bytecode for anyMammal.speak() and humanMammal.speak() is same because according to compiler both methods are called on Mammal reference but the output for both method calls is different because at runtime JVM knows what object a reference is holding and JVM calls the method on the object and this is why Method Overriding is known as Dynamic Polymorphism.
So from above code and bytecode, it is clear that during compilation phase calling method is considered from the reference type. But at execution time method will be called from the object which the reference is holding.
If you want to know more about this you can read more on How Does JVM Handle Method Overloading and Overriding Internally.
If you want to add N days to your days. You can use the plus operator as follows -

This is big endian test from a configure script:
#include <inttypes.h>
int main(int argc, char ** argv){
volatile uint32_t i=0x01234567;
// return 0 for big endian, 1 for little endian.
return (*((uint8_t*)(&i))) == 0x67;
}
Wrapping a <a>
around won't work (unless you set the <div>
to display:inline-block;
or display:block;
to the <a>
) because the div is s a block-level element and the <a>
is not.
<a href="http://www.example.com" style="display:block;">
<div>
content
</div>
</a>
<a href="http://www.example.com">
<div style="display:inline-block;">
content
</div>
</a>
<a href="http://www.example.com">
<span>
content
</span >
</a>
<a href="http://www.example.com">
content
</a>
But maybe you should skip the <div>
and choose a <span>
instead, or just the plain <a>
. And if you really want to make the div clickable, you could attach a javascript redirect with a onclick handler, somethign like:
document.getElementById("myId").setAttribute('onclick', 'location.href = "url"');
but I would recommend against that.
(This is already answered in comments, but since it lacks an actual answer, I'm writing this.)
This problem arises in newer versions of Visual C++ (the older versions usually just silently linked the program and it would crash and burn at run time.) It means that some of the libraries you are linking with your program (or even some of the source files inside your program itself) are using different versions of the CRT (the C RunTime library.)
To correct this error, you need to go into your Project Properties
(and/or those of the libraries you are using,) then into C/C++
, then Code Generation
, and check the value of Runtime Library
; this should be exactly the same for all the files and libraries you are linking together. (The rules are a little more relaxed for linking with DLLs, but I'm not going to go into the "why" and into more details here.)
There are currently four options for this setting:
Your particular problem seems to stem from you linking a library built with "Multithreaded Debug" (i.e. static multithreaded debug CRT) against a program that is being built using the "Multithreaded Debug DLL" setting (i.e. dynamic multithreaded debug CRT.) You should change this setting either in the library, or in your program. For now, I suggest changing this in your program.
Note that since Visual Studio projects use different sets of project settings for debug and release builds (and 32/64-bit builds) you should make sure the settings match in all of these project configurations.
For (some) more information, you can see these (linked from a comment above):
UPDATE: (This is in response to a comment that asks for the reason that this much care must be taken.)
If two pieces of code that we are linking together are themselves linking against and using the standard library, then the standard library must be the same for both of them, unless great care is taken about how our two code pieces interact and pass around data. Generally, I would say that for almost all situations just use the exact same version of the standard library runtime (regarding debug/release, threads, and obviously the version of Visual C++, among other things like iterator debugging, etc.)
The most important part of the problem is this: having the same idea about the size of objects on either side of a function call.
Consider for example that the above two pieces of code are called A
and B
. A is compiled against one version of the standard library, and B against another. In A's view, some random object that a standard function returns to it (e.g. a block of memory or an iterator or a FILE
object or whatever) has some specific size and layout (remember that structure layout is determined and fixed at compile time in C/C++.) For any of several reasons, B's idea of the size/layout of the same objects is different (it can be because of additional debug information, natural evolution of data structures over time, etc.)
Now, if A calls the standard library and gets an object back, then passes that object to B, and B touches that object in any way, chances are that B will mess that object up (e.g. write the wrong field, or past the end of it, etc.)
The above isn't the only kind of problems that can happen. Internal global or static objects in the standard library can cause problems too. And there are more obscure classes of problems as well.
All this gets weirder in some aspects when using DLLs (dynamic runtime library) instead of libs (static runtime library.)
This situation can apply to any library used by two pieces of code that work together, but the standard library gets used by most (if not almost all) programs, and that increases the chances of clash.
What I've described is obviously a watered down and simplified version of the actual mess that awaits you if you mix library versions. I hope that it gives you an idea of why you shouldn't do it!
Simply u can add this to jquery.validationEngine-en.js file
"onlyLetterNumberSp": {
"regex": ^[A-Za-z0-9 _]*[A-Za-z0-9][A-Za-z0-9 _]*$,
"alertText": "* No special characters allowed"
},
and call it in text field as
<input type="text" class="form-control validate[required,custom[onlyLetterNumberSp]]" id="title" name="title" placeholder="Title"/>
Use compareTo(BigDecimal.ZERO)
instead of equals()
:
if (price.compareTo(BigDecimal.ZERO) == 0) // see below
Comparing with the BigDecimal
constant BigDecimal.ZERO
avoids having to construct a new BigDecimal(0)
every execution.
FYI, BigDecimal
also has constants BigDecimal.ONE
and BigDecimal.TEN
for your convenience.
The reason you can't use BigDecimal#equals()
is that it takes scale into consideration:
new BigDecimal("0").equals(BigDecimal.ZERO) // true
new BigDecimal("0.00").equals(BigDecimal.ZERO) // false!
so it's unsuitable for a purely numeric comparison. However, BigDecimal.compareTo()
doesn't consider scale when comparing:
new BigDecimal("0").compareTo(BigDecimal.ZERO) == 0 // true
new BigDecimal("0.00").compareTo(BigDecimal.ZERO) == 0 // true
I couldn't get the compiler (x64
version) to use the sysroot
until I added SET(CMAKE_SYSROOT $ENV{HOME}/raspberrypi/rootfs)

I know this is an old question, but there is a simple, one line solution which works consistently for Chrome, Firefox, etc., as well as IE8 and above (and, for the most part, works on IE7 too - see http://www.quirksmode.org/css/selectors/ for details):
table td + td { border-left:2px solid red; }
The output is something like this:
Col1 | Col2 | Col3
What is making this work is that you are defining a border only on table cells which are adjacent to another table cell. In other words, you're applying the CSS to all cells in a row except the first one.
By applying a left border to the second through the last child, it gives the appearance of the line being "between" the cells.
I'd do it in two statements: DROP DATABASE ???
and then CREATE DATABASE ???
I suggest the use of htop, as a better alternative to top.
You can use attachEvent(ie8) and addEventListener instead
addEvent(window, 'load', function(){ some_methods_1() });
addEvent(window, 'load', function(){ some_methods_2() });
function addEvent(element, eventName, fn) {
if (element.addEventListener)
element.addEventListener(eventName, fn, false);
else if (element.attachEvent)
element.attachEvent('on' + eventName, fn);
}
Worked for me:
$(".filter-mobile").click(function() {
if ($("#menuProdutos").height() > 0) {
$("#menuProdutos").animate({
height: 0
}, 200);
} else {
$("#menuProdutos").animate({
height: 500
}, 200);
}
});
i tend to use this calculation a lot in things i make, so i like to add it to the Math object:
Math.dist=function(x1,y1,x2,y2){
if(!x2) x2=0;
if(!y2) y2=0;
return Math.sqrt((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1));
}
Math.dist(0,0, 3,4); //the output will be 5
Math.dist(1,1, 4,5); //the output will be 5
Math.dist(3,4); //the output will be 5
Update:
this approach is especially happy making when you end up in situations something akin to this (i often do):
varName.dist=Math.sqrt( ( (varName.paramX-varX)/2-cx )*( (varName.paramX-varX)/2-cx ) + ( (varName.paramY-varY)/2-cy )*( (varName.paramY-varY)/2-cy ) );
that horrid thing becomes the much more manageable:
varName.dist=Math.dist((varName.paramX-varX)/2, (varName.paramY-varY)/2, cx, cy);
You need to install VMware Tools on your vm:
To install VMware Tools in most VMware products:
Power on the virtual machine.
Log in to the virtual machine using an account with Administrator or root privileges.
Wait for the desktop to load and be ready.
Click Install/Upgrade VMware Tools. There are two places to find this option:
Right-click on the running virtual machine object and click Open Console. In the Console menu click VM and click Install/Upgrade VMware Tools.
Note: In ESX/ESXi 4.x, navigate to VM > Guest > Install/Upgrade VMware Tools. In Workstation, navigate to VM > Install/Upgrade VMware Tools.

Since 'Kranu' helpfully advises 'The only interaction with the filesystem is with loading js files . . .', that suggests doing so with error checking would at least tell you if the file does not exist - which may be sufficient for your purposes?
From a local machine, you can check whether a file does not exist by attempting to load it as an external script then checking for an error. For example:
<span>File exists? </span>
<SCRIPT>
function get_error(x){
document.getElementsByTagName('span')[0].innerHTML+=x+" does not exist.";
}
url=" (put your path/file name in here) ";
url+="?"+new Date().getTime()+Math.floor(Math.random()*1000000);
var el=document.createElement('script');
el.id="123";
el.onerror=function(){if(el.onerror)get_error(this.id)}
el.src=url;
document.body.appendChild(el);
</SCRIPT>
Some notes...
I used the approach with __file__
os.path.abspath(__file__)
but there is a little trick, it returns the .py file
when the code is run the first time,
next runs give the name of *.pyc file
so I stayed with:
inspect.getfile(inspect.currentframe())
or
sys._getframe().f_code.co_filename
You can not access the environment variable like this.
Inside the .env
file you write
IMAP_HOSTNAME_TEST=imap.gmail.com // I am okay with this
Next, inside the config
folder there is a file, mail.php. You may use this file to code. As you are working with mail functionality. You might use another file as well.
return [
//..... other declarations
'imap_hostname_test' => env('IMAP_HOSTNAME_TEST'),
// You are hiding the value inside the configuration as well
];
You can call the variable from a controller using 'config(
.
Whatever file you are using inside config folder. You need to use that file name (without extension) + '.' + 'variable name' + ')'
. In the current case you can call the variable as follows.
$hostname = config('mail.imap_hostname_test');
Since you declare the variable inside mail.php and the variable name is imap_hostname_test
, you need to call it like this. If you declare this variable inside app.php
then you should call
$hostname = config('app.imap_hostname_test');
You can easily set a pandas.DataFrame column to a constant. This constant can be an int such as in your example. If the column you specify isn't in the df, then pandas will create a new column with the name you specify. So after your dataframe is constructed, (from your question):
df = pd.DataFrame({'a':[np.nan, 2, 3], 'b':[4, 5, 6]}, index=[3, 5, 6])
You can just run:
df['s1'], df['s2'] = 5, 6
You could write a loop or comprehension to make it do this for all the elements in a list of tuples, or keys and values in a dictionary depending on how you have your real data stored.
In my case, for jboss 6.3
I had to change JAVA_OPTS
in file jboss-eap-6.3\bin\standalone.conf.bat
and set following values -Xmx8g -Xms8g -Xmn3080m
for jvm to take 8gb space.
We got around this by adding functions to the environment
step, i.e.:
environment {
ENVIRONMENT_NAME = defineEnvironment()
}
...
def defineEnvironment() {
def branchName = "${env.BRANCH_NAME}"
if (branchName == "master") {
return 'staging'
}
else {
return 'test'
}
}
.modalBackground
{
filter: alpha(opacity=80);
opacity: 0.8;
z-index: 10000;
}
Try this:
location / {
root /path/to/root;
expires 30d;
access_log off;
}
location ~* ^.*\.php$ {
if (!-f $request_filename) {
return 404;
}
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8080;
}
Hopefully it works. Regular expressions have higher priority than plain strings, so all requests ending in .php
should be forwared to Apache if only a corresponding .php
file exists. Rest will be handled as static files. The actual algorithm of evaluating location is here.

Windows Forms (and its visual designer) have been available for .NET Core (as a preview) since Visual Studio 2019 16.6. It's quite good, although sometimes I need to open Visual Studio 2019 16.7 Preview to get around annoying bugs.
See this blog post: Windows Forms Designer for .NET Core Released
Also, Windows Forms is now open source: https://github.com/dotnet/winforms
I normally do this in VB and its easier because Excel records macros in VB. So I normally go to Excel and save the macro I want to do.
So that's what I did now and I got this code:
Columns("E:E").ColumnWidth = 17.29;
Range("E3").Interior.Pattern = xlSolid;
Range("E3").Interior.PatternColorIndex = xlAutomatic;
Range("E3").Interior.Color = 65535;
Range("E3").Interior.TintAndShade = 0;
Range("E3").Interior.PatternTintAndShade = 0;
I think you can do something like this:
xlWorkSheet.Columns[5].ColumnWidth = 18;
For your last question what you need to do is loop trough the columns you want to set their width:
for (int i = 1; i <= 10; i++) // this will apply it from col 1 to 10
{
xlWorkSheet.Columns[i].ColumnWidth = 18;
}
unicode
is meant to handle text. Text is a sequence of code points which may be bigger than a single byte. Text can be encoded in a specific encoding to represent the text as raw bytes(e.g. utf-8
, latin-1
...).
Note that unicode
is not encoded! The internal representation used by python is an implementation detail, and you shouldn't care about it as long as it is able to represent the code points you want.
On the contrary str
in Python 2 is a plain sequence of bytes. It does not represent text!
You can think of unicode
as a general representation of some text, which can be encoded in many different ways into a sequence of binary data represented via str
.
Note: In Python 3, unicode
was renamed to str
and there is a new bytes
type for a plain sequence of bytes.
Some differences that you can see:
>>> len(u'à') # a single code point
1
>>> len('à') # by default utf-8 -> takes two bytes
2
>>> len(u'à'.encode('utf-8'))
2
>>> len(u'à'.encode('latin1')) # in latin1 it takes one byte
1
>>> print u'à'.encode('utf-8') # terminal encoding is utf-8
à
>>> print u'à'.encode('latin1') # it cannot understand the latin1 byte
?
Note that using str
you have a lower-level control on the single bytes of a specific encoding representation, while using unicode
you can only control at the code-point level. For example you can do:
>>> 'àèìòù'
'\xc3\xa0\xc3\xa8\xc3\xac\xc3\xb2\xc3\xb9'
>>> print 'àèìòù'.replace('\xa8', '')
à?ìòù
What before was valid UTF-8, isn't anymore. Using a unicode string you cannot operate in such a way that the resulting string isn't valid unicode text. You can remove a code point, replace a code point with a different code point etc. but you cannot mess with the internal representation.
If you want to use $.getJSON()
you can add the following before the call :
$.ajaxSetup({
scriptCharset: "utf-8",
contentType: "application/json; charset=utf-8"
});
You can use the charset you want instead of utf-8
.
The options are explained here.
contentType :
When sending data to the server, use this content-type
. Default is application/x-www-form-urlencoded
, which is fine for most cases.
scriptCharset :
Only for requests with jsonp
or script
dataType and GET type. Forces the request to be interpreted as a certain charset. Only needed for charset differences between the remote and local content.
You may need one or both ...
Basically the same solution as provided by Rutger Kassies, but using a more pythonic syntax:
fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k')
fig.subplots_adjust(hspace = .5, wspace=.001)
data = np.arange(250, 260)
for ax, d in zip(axs.ravel(), data):
ax.contourf(np.random.rand(10,10), 5, cmap=plt.cm.Oranges)
ax.set_title(str(d))
Quite an old article on mssqlcity attempts to explain the types of locks:
Shared locks are used for operations that do not change or update data, such as a SELECT statement.
Update locks are used when SQL Server intends to modify a page, and later promotes the update page lock to an exclusive page lock before actually making the changes.
Exclusive locks are used for the data modification operations, such as UPDATE, INSERT, or DELETE.
What it doesn't discuss are Intent (which basically is a modifier for these lock types). Intent (Shared/Exclusive) locks are locks held at a higher level than the real lock. So, for instance, if your transaction has an X lock on a row, it will also have an IX lock at the table level (which stops other transactions from attempting to obtain an incompatible lock at a higher level on the table (e.g. a schema modification lock) until your transaction completes or rolls back).
The concept of "sharing" a lock is quite straightforward - multiple transactions can have a Shared lock for the same resource, whereas only a single transaction may have an Exclusive lock, and an Exclusive lock precludes any transaction from obtaining or holding a Shared lock.
If you need a counter in an for-each loop you have to count yourself. There is no built in counter as far as I know.
You have a few options:
You may want to check that last step because i don't know for a fact that this is the appropriate service. I can't really test that right now. Good luck!

Interesting/funny way to do this using parameter expansion (requires bash 4.4
or newer):
${parameter@operator} - P operator
The expansion is a string that is the result of expanding the value of parameter as if it were a prompt string.

The way I was able to get this to work is as follows:
In the Edit Redirection Rules section of the S3 Console for your domain, add the following rules:
<RoutingRules>
<RoutingRule>
<Condition>
<HttpErrorCodeReturnedEquals>404</HttpErrorCodeReturnedEquals>
</Condition>
<Redirect>
<HostName>yourdomainname.com</HostName>
<ReplaceKeyPrefixWith>#!/</ReplaceKeyPrefixWith>
</Redirect>
</RoutingRule>
</RoutingRules>
This will redirect all paths that result in a 404 not found to your root domain with a hash-bang version of the path. So http://yourdomainname.com/posts will redirect to http://yourdomainname.com/#!/posts provided there is no file at /posts.
To use HTML5 pushStates however, we need to take this request and manually establish the proper pushState based on the hash-bang path. So add this to the top of your index.html file:
<script>
history.pushState({}, "entry page", location.hash.substring(1));
</script>
This grabs the hash and turns it into an HTML5 pushState. From this point on you can use pushStates to have non-hash-bang paths in your app.
