From what I remember you could use VMRuntime
class in early Android versions but now you just can't anymore.
I don't think letting the developer choose the heap size in a mobile environment can be considered so safe though. I think it's easier that you can find a way to modify the heap size in a specific device (not on the programming side) that by trying to modify it from the application itself.
With arrays in php, the foreach loop is always a pretty solution.
In this case it could be for example:
foreach($my_array as $number => $number_array)
{
foreach($number_array as $data = > $user_data)
{
print "Array number: $number, contains $data with $user_data. <br>";
}
}
Responsive meta tag
To ensure proper rendering and touch zooming for all devices, add the responsive viewport meta tag to your <head>
.
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
Your hack of decrementing the count at the end is exactly that -- a hack.
Far better to write your loop correctly in the first place, so it doesn't count the last line twice.
int main() {
int number_of_lines = 0;
std::string line;
std::ifstream myfile("textexample.txt");
while (std::getline(myfile, line))
++number_of_lines;
std::cout << "Number of lines in text file: " << number_of_lines;
return 0;
}
Personally, I think in this case, C-style code is perfectly acceptable:
int main() {
unsigned int number_of_lines = 0;
FILE *infile = fopen("textexample.txt", "r");
int ch;
while (EOF != (ch=getc(infile)))
if ('\n' == ch)
++number_of_lines;
printf("%u\n", number_of_lines);
return 0;
}
Edit: Of course, C++ will also let you do something a bit similar:
int main() {
std::ifstream myfile("textexample.txt");
// new lines will be skipped unless we stop it from happening:
myfile.unsetf(std::ios_base::skipws);
// count the newlines with an algorithm specialized for counting:
unsigned line_count = std::count(
std::istream_iterator<char>(myfile),
std::istream_iterator<char>(),
'\n');
std::cout << "Lines: " << line_count << "\n";
return 0;
}
In my case since I had a jump host or Bastion host on the way, and because the signatures on these bastion nodes had changed since they were imported into known_hosts file, I just needed to delete those entries/lines from the following file:
/Users/a.abdi-kelishami/.ssh/known_hosts
From above file, delete those lines referring to the bastion hosts.
if you are using MariaDB you can try this:
You need, for example:
<input type="text" name="idtest" value="<?php echo $idtest; ?>" />
The echo
function is what actually outputs the value of the variable.
I got pretty close to what I wanted by doing something like this
cat my.json | jq '.my.prefix[] | .primary_key + ":", (.sub.prefix[] | " - " + .sub_key)' | tr -d '"'
The output of which is close enough to yaml for me to usually import it into other tools without much problem. (I am still looking for a way to basicallt export a subset of the input json)
Take a look at this SO post answer and also look at this basic authentication tutorial from the urllib2 missing manual.
In order for urllib2 basic authentication to work, the http response must contain HTTP code 401 Unauthorized and a key "WWW-Authenticate"
with the value "Basic"
otherwise, Python won't send your login info, and you will need to either use Requests, or urllib.urlopen(url)
with your login in the url, or add a the header like in @Flowpoke's answer.
You can view your error by putting your urlopen
in a try block:
try:
urllib2.urlopen(urllib2.Request(url))
except urllib2.HTTPError, e:
print e.headers
print e.headers.has_key('WWW-Authenticate')
Keep in mind that what you're getting in a POST on the server-side is a key-value pair. You have values, but where is your key? In this case, you'll want to set the name
attribute of the buttons so that there's a key by which to access the value.
Additionally, in keeping with conventions, you'll want to change the type
of these input
s (buttons) to submit
so that they post their values to the form properly.
Also, what is your onclick
doing?
Sometimes your SVG will be inlined by React so you need quotes around it:
backgroundImage: `url("${Background}")`
otherwise it's invalid CSS and the browser dev tools will not show that you've set background-image at all.
To accessing member functions or variables from one scope to another scope (In your case one method to another method we need to refer method or variable with class object. and you can do it by referring with self keyword which refer as class object.
class YourClass():
def your_function(self, *args):
self.callable_function(param) # if you need to pass any parameter
def callable_function(self, *params):
print('Your param:', param)
Dependency

My solution was to select the maven profiles I had defined in my pom.xml in which I had declared the hibernate dependencies.
CTRL + ALT + P
in eclipse.
In my project I was experiencing this problem and many others because in my pom I have different profiles for supporting Glassfish 3, Glassfish 4 and also WildFly so I have differet versions of Hibernate per container as well as different Java compilation targets and so on. Selecting the active maven profiles resolved my issue.
Why not download the English Wikipedia? There are compressed SQL files of various sizes, and it should certainly be large enough for you
The main articles are XML, so inserting them into the db is a bit more of a problem, but you might find there are other files there that suit you. For example, the inter-page links SQL file is 2.3GB compressed. Have a look at https://en.wikipedia.org/wiki/Wikipedia:Database_download for more info.

Mike Nereson has this to say on his blog at:
http://blog.codehangover.com/load-multiple-contexts-into-spring/
There are a couple of ways to do this.
1. web.xml contextConfigLocation
Your first option is to load them all into your Web application context via the ContextConfigLocation element. You’re already going to have your primary applicationContext here, assuming you’re writing a web application. All you need to do is put some white space between the declaration of the next context.
<context-param> <param-name> contextConfigLocation </param-name> <param-value> applicationContext1.xml applicationContext2.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>
The above uses carriage returns. Alternatively, yo could just put in a space.
<context-param> <param-name> contextConfigLocation </param-name> <param-value> applicationContext1.xml applicationContext2.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>
2. applicationContext.xml import resource
Your other option is to just add your primary applicationContext.xml to the web.xml and then use import statements in that primary context.
In
applicationContext.xml
you might have…<!-- hibernate configuration and mappings --> <import resource="applicationContext-hibernate.xml"/> <!-- ldap --> <import resource="applicationContext-ldap.xml"/> <!-- aspects --> <import resource="applicationContext-aspects.xml"/>
Which strategy should you use?
1. I always prefer to load up via web.xml.
Because , this allows me to keep all contexts isolated from each other. With tests, we can load just the contexts that we need to run those tests. This makes development more modular too as components stay
loosely coupled
, so that in the future I can extract a package or vertical layer and move it to its own module.2. If you are loading contexts into a
non-web application
, I would use theimport
resource.
You can use time.time()
or time.clock()
before and after the block you want to time.
import time
t0 = time.time()
code_block
t1 = time.time()
total = t1-t0
This method is not as exact as timeit
(it does not average several runs) but it is straightforward.
time.time()
(in Windows and Linux) and time.clock()
(in Linux) are not precise enough for fast functions (you get total = 0). In this case or if you want to average the time elapsed by several runs, you have to manually call the function multiple times (As I think you already do in you example code and timeit does automatically when you set its number argument)
import time
def myfast():
code
n = 10000
t0 = time.time()
for i in range(n): myfast()
t1 = time.time()
total_n = t1-t0
In Windows, as Corey stated in the comment, time.clock()
has much higher precision (microsecond instead of second) and is preferred over time.time()
.
I am combining the solutions from answers of @FredFoo and @Renaud. My solution is able to apply @Renaud's preprocessing on the text corpus of @FredFoo and then display pairwise similarities where the similarity is greater than 0. I ran this code on Windows by installing python and pip first. pip is installed as part of python but you may have to explicitly do it by re-running the installation package, choosing modify and then choosing pip. I use the command line to execute my python code saved in a file "similarity.py". I had to execute the following commands:
>set PYTHONPATH=%PYTHONPATH%;C:\_location_of_python_lib_
>python -m pip install sklearn
>python -m pip install nltk
>py similarity.py
The code for similarity.py is as follows:
from sklearn.feature_extraction.text import TfidfVectorizer
import nltk, string
import numpy as np
nltk.download('punkt') # if necessary...
stemmer = nltk.stem.porter.PorterStemmer()
remove_punctuation_map = dict((ord(char), None) for char in string.punctuation)
def stem_tokens(tokens):
return [stemmer.stem(item) for item in tokens]
def normalize(text):
return stem_tokens(nltk.word_tokenize(text.lower().translate(remove_punctuation_map)))
corpus = ["I'd like an apple",
"An apple a day keeps the doctor away",
"Never compare an apple to an orange",
"I prefer scikit-learn to Orange",
"The scikit-learn docs are Orange and Blue"]
vect = TfidfVectorizer(tokenizer=normalize, stop_words='english')
tfidf = vect.fit_transform(corpus)
pairwise_similarity = tfidf * tfidf.T
#view the pairwise similarities
print(pairwise_similarity)
#check how a string is normalized
print(normalize("The scikit-learn docs are Orange and Blue"))
With ES6 syntax
import mongoose from "mongoose";
// Generate a new new ObjectId
const newId2 = new mongoose.Types.ObjectId();
// Convert string to ObjectId
const newId = new mongoose.Types.ObjectId('56cb91bdc3464f14678934ca');
for k, v in mydict.iteritems():
if v is None:
mydict[k] = ''
In a more general case, e.g. if you were adding or removing keys, it might not be safe to change the structure of the container you're looping on -- so using items
to loop on an independent list copy thereof might be prudent -- but assigning a different value at a given existing index does not incur any problem, so, in Python 2.any, it's better to use iteritems
.
In Python3 however the code gives AttributeError: 'dict' object has no attribute 'iteritems'
error. Use items()
instead of iteritems()
here.
Refer to this post.
Since assertThat

You need to take extra precautions when using user supplied data in HTML attributes. Because attributes has many more attack vectors than output inside HTML tags.
The only way to avoid XSS attacks is to encode everything except alphanumeric characters. Escape all characters with ASCII values less than 256 with the &#xHH; format. Which unfortunately may cause problems in your scenario, if you are using CSS classes and javascript to fetch those elements.
OWASP has a good description of how to mitigate HTML attribute XSS:
If some other portion of your layout is influencing the div
width you can set width:auto
and the div
(which is a block element) will fill the space
<div style="width:auto">
<div style="margin-left:45px;width:auto">
<asp:TextBox ID="txtTitle" runat="server" Width="100%"></asp:TextBox><br />
</div>
</div>
If that's still not working we may need to see more of your layout HTML/CSS
Use output buffering:
<?php
ob_start();
var_dump($someVar);
$result = ob_get_clean();
?>
This is what I found out in the documentation.
- I : send the file inline to the browser (default). The plug-in is used if available. The name given by name is used when one selects the "Save as" option on the link generating the PDF.
- D : send to the browser and force a file download with the name given by name.
- F : save to a local server file with the name given by name.
- S : return the document as a string (name is ignored).
- FI : equivalent to F + I option
- FD : equivalent to F + D option
- E : return the document as base64 mime multi-part email attachment (RFC 2045)
Do this, it works:
defaultConfig {
applicationId "com.example.maps"
minSdkVersion 15
targetSdkVersion 24
versionCode 1
versionName "1.0"
multiDexEnabled true
}
Here's a possible way to do it:
$string=exec('getmac');
$mac=substr($string, 0, 17);
echo $mac;
Quoting the README at https://github.com/mhammond/pywin32:
By far the easiest way to use pywin32 is to grab binaries from the most recent release
Just download the installer for your version of Python from https://github.com/mhammond/pywin32/releases and run it, and you're done.
None of the existing answers involve using a comparator, and therefore cannot be used in binary trees or for sorting. So I'm just gonna leave this here:
public static int compareIntArrays(int[] a, int[] b) {
if (a == null) {
return b == null ? 0 : -1;
}
if (b == null) {
return 1;
}
int cmp = a.length - b.length;
if (cmp != 0) {
return cmp;
}
for (int i = 0; i < a.length; i++) {
cmp = Integer.compare(a[i], b[i]);
if (cmp != 0) {
return cmp;
}
}
return 0;
}
use the builtin: (no need for tkinter)
s = input('->>')
print(s) # what you just typed); now use if's
There are many ways to convert an instance to a dictionary, with varying degrees of corner case handling and closeness to the desired result.
instance.__dict__
instance.__dict__
which returns
{'_foreign_key_cache': <OtherModel: OtherModel object>,
'_state': <django.db.models.base.ModelState at 0x7ff0993f6908>,
'auto_now_add': datetime.datetime(2018, 12, 20, 21, 34, 29, 494827, tzinfo=<UTC>),
'foreign_key_id': 2,
'id': 1,
'normal_value': 1,
'readonly_value': 2}
This is by far the simplest, but is missing many_to_many
, foreign_key
is misnamed, and it has two unwanted extra things in it.
model_to_dict
from django.forms.models import model_to_dict
model_to_dict(instance)
which returns
{'foreign_key': 2,
'id': 1,
'many_to_many': [<OtherModel: OtherModel object>],
'normal_value': 1}
This is the only one with many_to_many
, but is missing the uneditable fields.
model_to_dict(..., fields=...)
from django.forms.models import model_to_dict
model_to_dict(instance, fields=[field.name for field in instance._meta.fields])
which returns
{'foreign_key': 2, 'id': 1, 'normal_value': 1}
This is strictly worse than the standard model_to_dict
invocation.
query_set.values()
SomeModel.objects.filter(id=instance.id).values()[0]
which returns
{'auto_now_add': datetime.datetime(2018, 12, 20, 21, 34, 29, 494827, tzinfo=<UTC>),
'foreign_key_id': 2,
'id': 1,
'normal_value': 1,
'readonly_value': 2}
This is the same output as instance.__dict__
but without the extra fields.
foreign_key_id
is still wrong and many_to_many
is still missing.
The code for django's model_to_dict
had most of the answer. It explicitly removed non-editable fields, so removing that check and getting the ids of foreign keys for many to many fields results in the following code which behaves as desired:
from itertools import chain
def to_dict(instance):
opts = instance._meta
data = {}
for f in chain(opts.concrete_fields, opts.private_fields):
data[f.name] = f.value_from_object(instance)
for f in opts.many_to_many:
data[f.name] = [i.id for i in f.value_from_object(instance)]
return data
While this is the most complicated option, calling to_dict(instance)
gives us exactly the desired result:
{'auto_now_add': datetime.datetime(2018, 12, 20, 21, 34, 29, 494827, tzinfo=<UTC>),
'foreign_key': 2,
'id': 1,
'many_to_many': [2],
'normal_value': 1,
'readonly_value': 2}
Django Rest Framework's ModelSerialzer allows you to build a serializer automatically from a model.
from rest_framework import serializers
class SomeModelSerializer(serializers.ModelSerializer):
class Meta:
model = SomeModel
fields = "__all__"
SomeModelSerializer(instance).data
returns
{'auto_now_add': '2018-12-20T21:34:29.494827Z',
'foreign_key': 2,
'id': 1,
'many_to_many': [2],
'normal_value': 1,
'readonly_value': 2}
This is almost as good as the custom function, but auto_now_add is a string instead of a datetime object.
If you want a django model that has a better python command-line display, have your models child-class the following:
from django.db import models
from itertools import chain
class PrintableModel(models.Model):
def __repr__(self):
return str(self.to_dict())
def to_dict(instance):
opts = instance._meta
data = {}
for f in chain(opts.concrete_fields, opts.private_fields):
data[f.name] = f.value_from_object(instance)
for f in opts.many_to_many:
data[f.name] = [i.id for i in f.value_from_object(instance)]
return data
class Meta:
abstract = True
So, for example, if we define our models as such:
class OtherModel(PrintableModel): pass
class SomeModel(PrintableModel):
normal_value = models.IntegerField()
readonly_value = models.IntegerField(editable=False)
auto_now_add = models.DateTimeField(auto_now_add=True)
foreign_key = models.ForeignKey(OtherModel, related_name="ref1")
many_to_many = models.ManyToManyField(OtherModel, related_name="ref2")
Calling SomeModel.objects.first()
now gives output like this:
{'auto_now_add': datetime.datetime(2018, 12, 20, 21, 34, 29, 494827, tzinfo=<UTC>),
'foreign_key': 2,
'id': 1,
'many_to_many': [2],
'normal_value': 1,
'readonly_value': 2}
You need antMatcher
for multiple HttpSecurity
, see Spring Security Reference:
5.7 Multiple HttpSecurity
We can configure multiple HttpSecurity instances just as we can have multiple
<http>
blocks. The key is to extend theWebSecurityConfigurationAdapter
multiple times. For example, the following is an example of having a different configuration for URL’s that start with/api/
.@EnableWebSecurity public class MultiHttpSecurityConfig { @Autowired public void configureGlobal(AuthenticationManagerBuilder auth) { 1 auth .inMemoryAuthentication() .withUser("user").password("password").roles("USER").and() .withUser("admin").password("password").roles("USER", "ADMIN"); } @Configuration @Order(1) 2 public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter { protected void configure(HttpSecurity http) throws Exception { http .antMatcher("/api/**") 3 .authorizeRequests() .anyRequest().hasRole("ADMIN") .and() .httpBasic(); } } @Configuration 4 public static class FormLoginWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .anyRequest().authenticated() .and() .formLogin(); } } }
1 Configure Authentication as normal
2 Create an instance of
WebSecurityConfigurerAdapter
that contains@Order
to specify whichWebSecurityConfigurerAdapter
should be considered first.3 The
http.antMatcher
states that thisHttpSecurity
will only be applicable to URLs that start with/api/
4 Create another instance of
WebSecurityConfigurerAdapter
. If the URL does not start with/api/
this configuration will be used. This configuration is considered afterApiWebSecurityConfigurationAdapter
since it has an@Order
value after1
(no@Order
defaults to last).
In your case you need no antMatcher
, because you have only one configuration. Your modified code:
http
.authorizeRequests()
.antMatchers("/high_level_url_A/sub_level_1").hasRole('USER')
.antMatchers("/high_level_url_A/sub_level_2").hasRole('USER2')
.somethingElse() // for /high_level_url_A/**
.antMatchers("/high_level_url_A/**").authenticated()
.antMatchers("/high_level_url_B/sub_level_1").permitAll()
.antMatchers("/high_level_url_B/sub_level_2").hasRole('USER3')
.somethingElse() // for /high_level_url_B/**
.antMatchers("/high_level_url_B/**").authenticated()
.anyRequest().permitAll()
This should help you get rid of body margins and default top margin of <h1>
tag
body{
margin: 0px;
padding: 0px;
}
h1 {
margin-top: 0px;
}
#map {
float: right;
width: 700px;
height: 500px;
}
#list {
float:left;
width:200px;
background: #eee;
list-style: none;
padding: 0;
}
#similar {
float: left;
clear: left;
width: 200px;
background: #000;
}
Here is a relatively clean solution for others looking up this topic:
// run when eventlistener is triggered
$("#CompanyList").on( "autocompletechange", function(event,ui) {
// post value to console for validation
console.log($(this).val());
});
Per api.jqueryui.com/autocomplete/, this binds a function to the eventlistener. It is triggered both when the user selects a value from the autocomplete list and when they manually type in a value. The trigger fires when the field loses focus.
You could create a database for x conversations which contains all messages of these conversations. This would allow you to add a new Database (or server) each time x exceeds. X is the number conversations your infrastructure supports (depending on your hardware,...).
The problem is still, that there may be big conversations (with a lot of messages) on the same database. e.g. you have database A and database B an each stores e.g. 1000 conversations. It my be possible that there are far more "big" conversations on server A than on server B (since this is user created content). You could add a "master" database that contains a lookup, on which database/server the single conversations can be found (or you have a schema to assign a database from hash/modulo or something).
Maybe you can find real world architectures that deal with the same problems (you may not be the first one), and that have already been solved.
When using coding practice tools(LeetCode) it seems that size() is quicker than length() (although basically negligible)
Use Android Device Monitor
Android Device Monitor comes packages with android sdk which you would have installed previously. In the device monitor you can see you entire device log, exceptions, messages everything. This is usefully to debug application crashes or any other such problems. To run this, go to tools/ folder inside your android sdk “/var/android-sdk-linux/tools”. Then run the following
chmod +x monitor
./monitor
If you are on windows, directly open the monitor.exe file. There is a tab below “LogCat” where you will see all device related message. You will see all messages here including android device exceptions which are not visible chrome inspect device. Be sure to create filters using the “+” sign in logcat tab, so that you see messages only for your application.

I've just noticed that the answer that I upvoted and commented on is ambiguous. So the following is exactly what worked for me. I'm currently on Moment 2.26.0
and TS 3.8.3
:
In code:
import moment from 'moment';
In TS config:
{
"compilerOptions": {
"esModuleInterop": true,
...
}
}
I am building for both CommonJS and EMS so this config is imported into other config files.
The insight comes from this answer which relates to using Express. I figured it was worth adding here though, to help anyone who searches in relation to Moment.js, rather than something more general.
I picked node-sass implementer for libsass because it is based on node.js.
$ npm install -g node-sass
installs node-sass globally -g
.This will hopefully install all you need, if not read libsass at the bottom.
General format:
$ node-sass [options] <input.scss> [output.css]
$ cat <input.scss> | node-sass > output.css
Examples:
$ node-sass my-styles.scss my-styles.css
compiles a single file manually.$ node-sass my-sass-folder/ -o my-css-folder/
compiles all the files in a folder manually.$ node-sass -w sass/ -o css/
compiles all the files in a folder automatically whenever the source file(s) are modified. -w
adds a watch for changes to the file(s).More usefull options like 'compression' @ here. Command line is good for a quick solution, however, you can use task runners like Grunt.js or Gulp.js to automate the build process.
You can also add the above examples to npm scripts. To properly use npm scripts as an alternative to gulp read this comprehensive article @ css-tricks.com especially read about grouping tasks.
package.json
file in your project directory running $ npm init
will create one. Use it with -y
to skip the questions. "sass": "node-sass -w sass/ -o css/"
to scripts
in package.json
file. It should look something like this:"scripts": {
"test" : "bla bla bla",
"sass": "node-sass -w sass/ -o css/"
}
$ npm run sass
will compile your files.$ npm install -g gulp
installs Gulp globally.package.json
file in your project directory running $ npm init
will create one. Use it with -y
to skip the questions.$ npm install --save-dev gulp
installs Gulp locally. --save-dev
adds gulp
to devDependencies
in package.json
.$ npm install gulp-sass --save-dev
installs gulp-sass locally.gulpfile.js
file in your project root folder with this content:'use strict';
var gulp = require('gulp');
A basic example to transpile
Add this code to your gulpfile.js:
var gulp = require('gulp');
var sass = require('gulp-sass');
gulp.task('sass', function () {
gulp.src('./sass/**/*.scss')
.pipe(sass().on('error', sass.logError))
.pipe(gulp.dest('./css'));
});
$ gulp sass
runs the above task which compiles .scss file(s) in the sass
folder and generates .css file(s) in the css
folder.
To make life easier, let's add a watch so we don't have to compile it manually. Add this code to your gulpfile.js
:
gulp.task('sass:watch', function () {
gulp.watch('./sass/**/*.scss', ['sass']);
});
All is set now! Just run the watch task:
$ gulp sass:watch
As the name of node-sass implies, you can write your own node.js scripts for transpiling. If you are curious, check out node-sass project page.
Libsass is a library that needs to be built by an implementer such as sassC or in our case node-sass. Node-sass contains a built version of libsass which it uses by default. If the build file doesn't work on your machine, it tries to build libsass for your machine. This process requires Python 2.7.x (3.x doesn't work as of today). In addition:
LibSass requires GCC 4.6+ or Clang/LLVM. If your OS is older, this version may not compile. On Windows, you need MinGW with GCC 4.6+ or VS 2013 Update 4+. It is also possible to build LibSass with Clang/LLVM on Windows.
You simply don't call the function.
>>>def x():
>>> print(20)
>>>y = x
>>>y()
20
The brackets tell python that you are calling the function, so when you put them there, it calls the function and assigns y
the value returned by x
(which in this case is None
).

function videoViews() {
var rex = /[a-zA-Z0-9\-\_]{11}/,
videoUrl = $('input').val() === '' ? alert('Enter a valid Url'):$('input').val(),
videoId = videoUrl.match(rex),
jsonUrl = 'http://gdata.youtube.com/feeds/api/videos/' + videoId + '?v=2&alt=json',
embedUrl = '//www.youtube.com/embed/' + videoId,
embedCode = '<iframe width="350" height="197" src="' + embedUrl + '" frameborder="0" allowfullscreen></iframe>'
//Get Views from JSON
$.getJSON(jsonUrl, function (videoData) {
var videoJson = JSON.stringify(videoData),
vidJson = JSON.parse(videoJson),
views = vidJson.entry.yt$statistics.viewCount;
$('.views').text(views);
});
//Embed Video
$('.videoembed').html(embedCode);}
If you would like to handle multiple inputs with one handler take a look at my approach where I'm using computed property
to get value of the input based on it's name.
import React, { useState } from "react";
import "./style.css";
export default function App() {
const [state, setState] = useState({
name: "John Doe",
email: "[email protected]"
});
const handleChange = e => {
setState({
[e.target.name]: e.target.value
});
};
return (
<div>
<input
type="text"
className="name"
name="name"
value={state.name}
onChange={handleChange}
/>
<input
type="text"
className="email"
name="email"
value={state.email}
onChange={handleChange}
/>
</div>
);
}
On events "Enter" (for example: press Tab key) or "First Click" all text will be selected. dotNET 4.0
public static class TbHelper
{
// Method for use
public static void SelectAllTextOnEnter(TextBox Tb)
{
Tb.Enter += new EventHandler(Tb_Enter);
Tb.Click += new EventHandler(Tb_Click);
}
private static TextBox LastTb;
private static void Tb_Enter(object sender, EventArgs e)
{
var Tb = (TextBox)sender;
Tb.SelectAll();
LastTb = Tb;
}
private static void Tb_Click(object sender, EventArgs e)
{
var Tb = (TextBox)sender;
if (LastTb == Tb)
{
Tb.SelectAll();
LastTb = null;
}
}
}
You can also use flexbox, but you'd have to add a parent div that covers div#top
and div#term-defs
. So the HTML looks like this:
#content {_x000D_
width: 100%;_x000D_
height: 100%;_x000D_
display: flex;_x000D_
flex-direction: column;_x000D_
}_x000D_
_x000D_
#term-defs {_x000D_
flex-grow: 1;_x000D_
overflow: auto;_x000D_
}
_x000D_
<body>_x000D_
<div id="content">_x000D_
<div id="top">_x000D_
<a href="#A">A</a> |_x000D_
<a href="#B">B</a> |_x000D_
<a href="#Z">Z</a>_x000D_
</div>_x000D_
_x000D_
<div id="term-defs">_x000D_
<dl>_x000D_
<span id="A"></span>_x000D_
<dt>foo</dt>_x000D_
<dd>This is the sound made by a fool</dd>_x000D_
<!-- and so on ... -->_x000D_
</dl>_x000D_
</div>_x000D_
</div>_x000D_
</body>
_x000D_
flex-grow
ensures that the div's size is equal to the remaining size.
You could do the same without flexbox, but it would be more complicated to work out the height of #term-defs
(you'd have to know the height of #top
and use calc(100% - 999px)
or set the height of #term-defs
directly).
With flexbox dynamic sizes of the divs are possible.
One difference is that the scrollbar only appears on the term-defs div
.
In SQL you need to use GETDATE()
:
UPDATE table SET date = GETDATE();
There is no NOW()
function.
To answer your question:
In a large table, since the function is evaluated for each row, you will end up getting different values for the updated field.
So, if your requirement is to set it all to the same date I would do something like this (untested):
DECLARE @currDate DATETIME;
SET @currDate = GETDATE();
UPDATE table SET date = @currDate;
Override service method like this:
protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
And Voila!
You should write something like
*.class
into your .gitignore
file.
It means that a Lambda expression of type TDelegate
which contains a ([parameters]) => { some code };
cannot be converted to an Expression<TDelegate>
. It's the rule.
Simplify your query. The one you provided can be rewritten as the following and will compile:
Arr[] myArray = objects.Select(o => new Obj()
{
Var1 = o.someVar,
Var2 = o.var2
} ).ToArray();
Add the -v
option to your grep
command to invert the results.
Note that Internet Explorer from version 5 up to 8 will throw an error when trying to download a file served via https and the server sending Cache-Control: no-cache
or Pragma: no-cache
headers.
See http://support.microsoft.com/kb/812935/en-us
The use of Cache-Control: no-store
and Pragma: private
seems to be the closest thing which still works.

Here is a util class for marshaling and unmarshaling objects. In my case it was a nested class, so I made it static JAXBUtils.
import javax.xml.bind.JAXB;
import java.io.StringReader;
import java.io.StringWriter;
public class JAXBUtils
{
/**
* Unmarshal an XML string
* @param xml The XML string
* @param type The JAXB class type.
* @return The unmarshalled object.
*/
public <T> T unmarshal(String xml, Class<T> type)
{
StringReader reader = new StringReader(xml);
return javax.xml.bind.JAXB.unmarshal(reader, type);
}
/**
* Marshal an Object to XML.
* @param object The object to marshal.
* @return The XML string representation of the object.
*/
public String marshal(Object object)
{
StringWriter stringWriter = new StringWriter();
JAXB.marshal(object, stringWriter);
return stringWriter.toString();
}
}
I had similar issue. In my case on disabled elements was applied that aspNetDisabled class and all disabled controls had wrong colors. So, I used jquery to remove this class on every element/control I wont and everything works and looks great now.
This is my code for removing aspNetDisabled class:
$(document).ready(function () {
$("span").removeClass("aspNetDisabled");
$("select").removeClass("aspNetDisabled");
$("input").removeClass("aspNetDisabled");
});
I wrote some code to expose the Elasticsearch API via a Filesystem API.
It is good idea for clear export/import of data for example.
I created prototype elasticdriver. It is based on FUSE
You are just missing the words "primary key" as far as I can see to meet your specified objective.
For your other columns it's best to explicitly define whether they should be NULL
or NOT NULL
though so you are not relying on the ANSI_NULL_DFLT_ON
setting.
CREATE TABLE #tmp
(
ID INT IDENTITY(1, 1) primary key ,
AssignedTo NVARCHAR(100),
AltBusinessSeverity NVARCHAR(100),
DefectCount int
);
insert into #tmp
select 'user','high',5 union all
select 'user','med',4
select * from #tmp
If you want to show time on textview then better use Chronometer or TextClock
Using Chronometer:This was added in API 1. It has lot of option to customize it.
Your xml
<Chronometer
android:id="@+id/chronometer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="30sp" />
Your activity
Chronometer mChronometer=(Chronometer) findViewById(R.id.chronometer);
mChronometer.setBase(SystemClock.elapsedRealtime());
mChronometer.start();
Using TextClock: This widget is introduced in API level 17. I personally like Chronometer.
Your xml
<TextClock
android:id="@+id/textClock"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp"
android:format12Hour="hh:mm:ss a"
android:gravity="center_horizontal"
android:textColor="#d41709"
android:textSize="44sp"
android:textStyle="bold" />
Thats it, you are done.
You can use any of these two widgets. This will make your life easy.
i think there should be entry of your your_module.ko in /lib/modules/uname -r
/modules.dep and in /lib/modules/uname -r
/modules.dep.bin for "modprobe your_module" command to work
could be a shorthand for React.Fragment
In short, yes. I assume you're looking to parse English: for that you can use the Link Parser from Carnegie Mellon.
It is important to remember that there are many theories of syntax, that can give completely different-looking phrase structure trees; further, the trees are different for each language, and tools may not exist for those languages.
As a note for the future: if you need a sentence parsed out and tag it as linguistics
(and syntax
or whatnot, if that's available), someone can probably parse it out for you and guide you through it.
If you are looking for answer in string values , try this
var check = moment('date/utc format');
day = check.format('dddd') // => ('Monday' , 'Tuesday' ----)
month = check.format('MMMM') // => ('January','February.....)
year = check.format('YYYY') // => ('2012','2013' ...)
None of the upvoted solutions worked for me. Here's what eventually worked:
I moved the code which was in $(document).ready
out, if it wasn't required in document ready. If it's mandatory to have it in document ready, then you move that critical code to jQuery(window).load()
.
I've seen some people recommending installing aditional software but in my opinion the best way is by using the built-in skins, you can find them at:
Tools > Preferences > Syntax Coloring
I'm new to python too. Here is something that looks like will do what you want to
axes([0.08, 0.08, 0.94-0.08, 0.94-0.08]) #[left, bottom, width, height]
axis('scaled')`
I believe this decides the size of the canvas.
MySQL 5.x specification for decimal datatype is: DECIMAL[(M[,D])] [UNSIGNED] [ZEROFILL]
. The answer above is wrong (now corrected) in saying that unsigned decimals are not possible.
To define a field allowing only unsigned decimals, with a total length of 6 digits, 4 of which are decimals, you would use: DECIMAL (6,4) UNSIGNED
.
You can likewise create unsigned (ie. not negative) FLOAT and DOUBLE datatypes.
Update on MySQL 8.0.17+, as in MySQL 8 Manual: 11.1.1 Numeric Data Type Syntax:
"Numeric data types that permit the UNSIGNED attribute also permit SIGNED. However, these data types are signed by default, so the SIGNED attribute has no effect.*
As of MySQL 8.0.17, the UNSIGNED attribute is deprecated for columns of type FLOAT, DOUBLE, and DECIMAL (and any synonyms); you should expect support for it to be removed in a future version of MySQL. Consider using a simple CHECK constraint instead for such columns.
Use GetLength(), rather than Length.
int rowsOrHeight = ary.GetLength(0);
int colsOrWidth = ary.GetLength(1);

You can't see this method in javadoc because it's added by the compiler.
Documented in three places :
The compiler automatically adds some special methods when it creates an enum. For example, they have a static values method that returns an array containing all of the values of the enum in the order they are declared. This method is commonly used in combination with the for-each construct to iterate over the values of an enum type.
Enum.valueOf
classvalues
method is mentioned in description of valueOf
method)All the constants of an enum type can be obtained by calling the implicit public static T[] values() method of that type.
The values
function simply list all values of the enumeration.
Since you want to pivot multiple columns of data, I would first suggest unpivoting the result
, score
and grade
columns so you don't have multiple columns but you will have multiple rows.
Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:
select ratio = col,
[current ratio], [gearing ratio], [performance ratio], total
from
(
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
) d
pivot
(
max(value)
for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;
See SQL Fiddle with Demo. This will give you the result:
| RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO | TOTAL |
|--------|---------------|---------------|-------------------|-----------|
| grade | Good | Good | Satisfactory | Good |
| result | 1.29400 | 0.33840 | 0.04270 | (null) |
| score | 60.00000 | 70.00000 | 50.00000 | 180.00000 |
ClassLoader loader = Thread.currentThread().getContextClassLoader();
InputStream is = loader.getResourceAsStream("test.csv");
If you use context ClassLoader to find a resource then definitely it will cost application performance.
Since struct instances are allocated on stack, and class instances are allocated on heap, structs can sometimes be drastically faster.
However, you should always measure it yourself and decide based on your unique use case.
Consider the following example, which demonstrates 2 strategies of wrapping Int
data type using struct
and class
. I am using 10 repeated values are to better reflect real world, where you have multiple fields.
class Int10Class {
let value1, value2, value3, value4, value5, value6, value7, value8, value9, value10: Int
init(_ val: Int) {
self.value1 = val
self.value2 = val
self.value3 = val
self.value4 = val
self.value5 = val
self.value6 = val
self.value7 = val
self.value8 = val
self.value9 = val
self.value10 = val
}
}
struct Int10Struct {
let value1, value2, value3, value4, value5, value6, value7, value8, value9, value10: Int
init(_ val: Int) {
self.value1 = val
self.value2 = val
self.value3 = val
self.value4 = val
self.value5 = val
self.value6 = val
self.value7 = val
self.value8 = val
self.value9 = val
self.value10 = val
}
}
func + (x: Int10Class, y: Int10Class) -> Int10Class {
return IntClass(x.value + y.value)
}
func + (x: Int10Struct, y: Int10Struct) -> Int10Struct {
return IntStruct(x.value + y.value)
}
Performance is measured using
// Measure Int10Class
measure("class (10 fields)") {
var x = Int10Class(0)
for _ in 1...10000000 {
x = x + Int10Class(1)
}
}
// Measure Int10Struct
measure("struct (10 fields)") {
var y = Int10Struct(0)
for _ in 1...10000000 {
y = y + Int10Struct(1)
}
}
func measure(name: String, @noescape block: () -> ()) {
let t0 = CACurrentMediaTime()
block()
let dt = CACurrentMediaTime() - t0
print("\(name) -> \(dt)")
}

Just after your Page_Load add this:

{
//base.VerifyRenderingInServerForm(control);
}
Note that I don't do anything in the function.
EDIT: Tim answered the same thing. :) You can also find the answer Here
With the code in the question, you're only dealing interacting with the first of the four entries returned by that selector.
Code below as a fiddle: https://jsfiddle.net/c4nhpqgb/
I want to be overly clear that you have four items that matched that selector, so you need to deal with each explicitly. Using eq()
is a little more explicit making this point than the answers using map
, though map
or each
is what you'd probably use "in real life" (jquery docs for eq
here).
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>
</head>
<body>
<div class="mbox">Block One</div>
<div class="mbox">Block Two</div>
<div class="mbox">Block Three</div>
<div class="mbox">Block Four</div>
<div id="outige"></div>
<script>
// using the $ prefix to use the "jQuery wrapped var" convention
var i, $mvar = $('.mbox');
// convenience method to display unprocessed html on the same page
function logit( string )
{
var text = document.createTextNode( string );
$('#outige').append(text);
$('#outige').append("<br>");
}
logit($mvar.length);
for (i=0; i<$mvar.length; i++) {
logit($mvar.eq(i).html());
}
</script>
</body>
</html>

You could use the head
instead of cat
:
head -n1 /etc/*release | awk '{print $1}'
UIColor's RGB components are scaled between 0 and 1, not up to 255.
Try
categoryTitle.textColor = [UIColor colorWithRed:(188/255.f) green:... blue:... alpha:1.0];
In Swift:
categoryTitle.textColor = UIColor(red: 188/255.0, green: ..., blue: ..., alpha: 1)
You must specify which type the response is
this.productService.getProducts().subscribe(res => {
this.productsArray = res;
});
Try this
this.productService.getProducts().subscribe((res: Product[]) => {
this.productsArray = res;
});
Consider using subtree instead of submodules, it will make your repo users life much easier. You may find more detailed guide in Pro Git book.
The recommended way to do date/time manipulation is to use a Calendar
object:
Calendar cal = Calendar.getInstance(); // locale-specific
cal.setTime(dateObject);
cal.set(Calendar.HOUR_OF_DAY, 0);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
long time = cal.getTimeInMillis();
Complementary at @Radu answer, As in SQL, you can add the table name in the parameter if you have many table with the same attribute.
.order_by("TableName.name desc")
The options discussed above won't work because they are not part of the CSS
specification (it is jQuery
extension). Having spent 2-3 days digging around for information, I found that the only way to select the Text of the selected option from the drop down is:
{ $("select", id:"Some_ID").find("option[selected='selected']")}
Refer to additional notes below:
Because :selected is a jQuery
extension and not part of the CSS
specification, queries using :selected cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :selected to select elements, first select the elements using a pure CSS
selector, then use .filter(":selected")
. (copied from: http://api.jquery.com/selected-selector/)
I found the solution to the problem of serializing entities was as follows:
#config/config.yml
services:
serializer.method:
class: Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer
serializer.encoder.json:
class: Symfony\Component\Serializer\Encoder\JsonEncoder
serializer:
class: Symfony\Component\Serializer\Serializer
arguments:
- [@serializer.method]
- {json: @serializer.encoder.json }
in my controller:
$serializer = $this->get('serializer');
$entity = $this->get('doctrine')
->getRepository('myBundle:Entity')
->findOneBy($params);
$collection = $this->get('doctrine')
->getRepository('myBundle:Entity')
->findBy($params);
$toEncode = array(
'response' => array(
'entity' => $serializer->normalize($entity),
'entities' => $serializer->normalize($collection)
),
);
return new Response(json_encode($toEncode));
other example:
$serializer = $this->get('serializer');
$collection = $this->get('doctrine')
->getRepository('myBundle:Entity')
->findBy($params);
$json = $serializer->serialize($collection, 'json');
return new Response($json);
you can even configure it to deserialize arrays in http://api.symfony.com/2.0
I like this function for the job
function randomKey($length) {
$pool = array_merge(range(0,9), range('a', 'z'),range('A', 'Z'));
for($i=0; $i < $length; $i++) {
$key .= $pool[mt_rand(0, count($pool) - 1)];
}
return $key;
}
echo randomKey(20);
set myDIR=LOG
IF not exist %myDIR% (mkdir %myDIR%)
What is the best practice on where the logic for the @foreach should be at?
Nowhere, just get rid of it. You could use editor or display templates.
So for example:
@foreach (var item in Model.Foos)
{
<div>@item.Bar</div>
}
could perfectly fine be replaced by a display template:
@Html.DisplayFor(x => x.Foos)
and then you will define the corresponding display template (if you don't like the default one). So you would define a reusable template ~/Views/Shared/DisplayTemplates/Foo.cshtml
which will automatically be rendered by the framework for each element of the Foos collection (IEnumerable<Foo> Foos { get; set; }
):
@model Foo
<div>@Model.Bar</div>
Obviously exactly the same conventions apply for editor templates which should be used in case you want to show some input fields allowing you to edit the view model in contrast to just displaying it as readonly.
I found the various answers really elegant (especially Alex Martelli's) but I wanted to quantify performance first hand, so I cooked up the following script:
from itertools import repeat
N = 10000000
def payload(a):
pass
def standard(N):
for x in range(N):
payload(None)
def underscore(N):
for _ in range(N):
payload(None)
def loopiter(N):
for _ in repeat(None, N):
payload(None)
def loopiter2(N):
for _ in map(payload, repeat(None, N)):
pass
if __name__ == '__main__':
import timeit
print("standard: ",timeit.timeit("standard({})".format(N),
setup="from __main__ import standard", number=1))
print("underscore: ",timeit.timeit("underscore({})".format(N),
setup="from __main__ import underscore", number=1))
print("loopiter: ",timeit.timeit("loopiter({})".format(N),
setup="from __main__ import loopiter", number=1))
print("loopiter2: ",timeit.timeit("loopiter2({})".format(N),
setup="from __main__ import loopiter2", number=1))
I also came up with an alternative solution that builds on Martelli's one and uses map()
to call the payload function. OK, I cheated a bit in that I took the freedom of making the payload accept a parameter that gets discarded: I don't know if there is a way around this. Nevertheless, here are the results:
standard: 0.8398549720004667
underscore: 0.8413165839992871
loopiter: 0.7110594899968419
loopiter2: 0.5891903560004721
so using map yields an improvement of approximately 30% over the standard for loop and an extra 19% over Martelli's.
Option 1
Use float:left
on both div
elements and set a % width for both div elements with a combined total width of 100%.
Use box-sizing: border-box;
on the floating div elements. The value border-box forces the padding and borders into the width and height instead of expanding it.
Use clearfix on the <div id="wrapper">
to clear the floating child elements which will make the wrapper div scale to the correct height.
.clearfix:after {
content: " ";
visibility: hidden;
display: block;
height: 0;
clear: both;
}
#first, #second{
box-sizing: border-box;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
}
#wrapper {
width: 500px;
border: 1px solid black;
}
#first {
border: 1px solid red;
float:left;
width:50%;
}
#second {
border: 1px solid green;
float:left;
width:50%;
}
http://jsfiddle.net/dqC8t/3381/
Option 2
Use position:absolute
on one element and a fixed width on the other element.
Add position:relative to <div id="wrapper">
element to make child elements absolutely position to the <div id="wrapper">
element.
#wrapper {
width: 500px;
border: 1px solid black;
position:relative;
}
#first {
border: 1px solid red;
width:100px;
}
#second {
border: 1px solid green;
position:absolute;
top:0;
left:100px;
right:0;
}
http://jsfiddle.net/dqC8t/3382/
Option 3
Use display:inline-block
on both div
elements and set a % width for both div elements with a combined total width of 100%.
And again (same as float:left
example) use box-sizing: border-box;
on the div elements. The value border-box forces the padding and borders into the width and height instead of expanding it.
NOTE: inline-block elements can have spacing issues as it is affected by spaces in HTML markup. More information here: https://css-tricks.com/fighting-the-space-between-inline-block-elements/
#first, #second{
box-sizing: border-box;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
}
#wrapper {
width: 500px;
border: 1px solid black;
position:relative;
}
#first {
width:50%;
border: 1px solid red;
display:inline-block;
}
#second {
width:50%;
border: 1px solid green;
display:inline-block;
}

A final option would be to use the new display option named flex, but note that browser compatibility might come in to play:
http://caniuse.com/#feat=flexbox
http://www.sketchingwithcss.com/samplechapter/cheatsheet.html
Remove all br
tags and use display: table
.
.text span {
background: rgba(165, 220, 79, 0.8);
display: table;
padding: 7px 10px;
color: white;
}
.fullscreen .large { font-size: 80px }
Explanation: The table wraps the width of its content by default without setting a width, but is still a block level element. You can get the same behavior by setting a width to other block-level elements:
<span style="display:block;border:1px solid red;width:100px;">Like a default table.</span>
<code>null</code>
Notice the <code>
element doesn't flow inline with the <span>
like it would normally. Check it out with the computed styles in your dev tools. You'll see pseudo margin to the right of the <span>
. Anyway, this is the same as the table, but the table has the added benefit of always forming to the width of its content.
Open your workspace\.metadata\.log
file. That will tell you usually what is going wrong.
A direction quotation from the documentation on 5.3. Tuples and Sequences:
Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain a heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.
Isn't easier than doing like :
1- Install jquery in your project:
yarn add jquery
2- Import jquery and start playing with DOM:
import $ from 'jquery';
In the component, you might want to try this:
import {NavigationEnd, NavigationStart, Router} from '@angular/router';
constructor(private router: Router) {
router.events.subscribe(
(event) => {
if (event instanceof NavigationStart)
// start loading pages
if (event instanceof NavigationEnd) {
// end of loading paegs
}
});
}
In your particular case the issue seem to be with accessing the site from non-canonical url (www.site.com vs. site.com).
Instead of fixing CORS issue (which may require writing proxy to server fonts with proper CORS headers depending on service provider) you can normalize your Urls to always server content on canonical Url and simply redirect if one requests page without "www.".
Alternatively you can upload fonts to different server/CDN that is known to have CORS headers configured or you can easily do so.
From Eclipse, the ^M
characters can be embedded in a line, and you want to convert them to newlines.
:s/\r/\r/g
You could use absolute positioning to pin the footer to the base of the parent div. I have also added 10px padding-bottom to the wrap (match the height of the footer). The absolute positioning is relative to the parent div rather than outside of the flow since you have already given it the position relative attribute.
body{ height:20000px }
#wrapper {padding:10%;}
#wrap{
float: left;
padding-bottom: 10px;
position: relative;
width: 40%;
background:#ccc;
}
#fixed{
position:absolute;
width:100%;
left: 0;
bottom: 0;
padding:0px;
height:10px;
background-color:#333;
}
If you are using PyDev in Eclipse, its Ctrl0 and Ctrl9 for collapse all and uncollapse all respectively. Ctrl- and Ctrl= to collapse individual methods when your cursor is on the line of the method declaration.
Range("C1:C10").Formula = "=A1+B1"
Simple as that.
It autofills (FillDown) the range with the formula.
A new way using ES6
let picked_element = array.filter(element => element.id === 0);
Starting from C# 8, you simply can use Range Operator. It's the more efficient and better way to handle such cases.
string AnString = "Hello World!";
AnString = AnString[10..];
It's 2020 now, use python3 consistently

If you are already debugging, you can hover over the function and the tooltip will allow you to navigate directly to the function definition:
Further Reading:
It is possible to use the DataFrame style property to highlight the background color of the cells where there is a difference.
Using the example data from the original question
The first step is to concatenate the DataFrames horizontally with the concat
function and distinguish each frame with the keys
parameter:
df_all = pd.concat([df.set_index('id'), df2.set_index('id')],
axis='columns', keys=['First', 'Second'])
df_all
It's probably easier to swap the column levels and put the same column names next to each other:
df_final = df_all.swaplevel(axis='columns')[df.columns[1:]]
df_final
Now, its much easier to spot the differences in the frames. But, we can go further and use the style
property to highlight the cells that are different. We define a custom function to do this which you can see in this part of the documentation.
def highlight_diff(data, color='yellow'):
attr = 'background-color: {}'.format(color)
other = data.xs('First', axis='columns', level=-1)
return pd.DataFrame(np.where(data.ne(other, level=0), attr, ''),
index=data.index, columns=data.columns)
df_final.style.apply(highlight_diff, axis=None)
This will highlight cells that both have missing values. You can either fill them or provide extra logic so that they don't get highlighted.
You could use the checked selector to grab only the selected ones (negating the need to know the count or to iterate over them all yourself):
$("input[name='user_group[]']:checked")
With those checked items, you can either create a collection of those values or do something to the collection:
var values = new Array();
$.each($("input[name='user_group[]']:checked"), function() {
values.push($(this).val());
// or you can do something to the actual checked checkboxes by working directly with 'this'
// something like $(this).hide() (only something useful, probably) :P
});
XLSx in the new Office is just a zipped collection of XML and other files. So you could generate that and zip it accordingly.
Bonus: you can create a very nice template with styles and so on:
content.xml
(or xl/worksheets/sheet1.xml
) with your dataHowever I found ODS (openoffice) much more approachable (excel can still open it), here is what I found in content.xml
<table:table-row table:style-name="ro1">
<table:table-cell office:value-type="string" table:style-name="ce1">
<text:p>here be a1</text:p>
</table:table-cell>
<table:table-cell office:value-type="string" table:style-name="ce1">
<text:p>here is b1</text:p>
</table:table-cell>
<table:table-cell table:number-columns-repeated="16382"/>

The easiest thing is if you can make the WPF bitmap from a file directly.
Otherwise you will have to use System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap.
The add
methods do not add duplicate classes and the remove
method only removes class with exact string match.
const addClass = (selector, classList) => {
const element = document.querySelector(selector);
const classes = classList.split(' ')
classes.forEach((item, id) => {
element.classList.add(item)
})
}
const removeClass = (selector, classList) => {
const element = document.querySelector(selector);
const classes = classList.split(' ')
classes.forEach((item, id) => {
element.classList.remove(item)
})
}
addClass('button.submit', 'text-white color-blue') // add text-white and color-blue classes
removeClass('#home .paragraph', 'text-red bold') // removes text-red and bold classes
If you want to manage key misses you should use TryGetValue
https://msdn.microsoft.com/en-gb/library/bb347013(v=vs.110).aspx
string value = "";
if (openWith.TryGetValue("tif", out value))
{
Console.WriteLine("For key = \"tif\", value = {0}.", value);
}
else
{
Console.WriteLine("Key = \"tif\" is not found.");
}
Instead of making a touchable UIImageView then placing it on the navbar, you should just create a UIBarButtonItem, which you make out of a UIImageView.
First make the image view:
UIImageView *yourImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"nameOfYourImage.png"]];
Then make the barbutton item out of your image view:
UIBarButtonItem *yourBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:yourImageView];
Then add the bar button item to your navigation bar:
self.navigationItem.rightBarButtonItem = yourBarButtonItem;
Remember that this code goes into the view controller which is inside a navigation controller viewcontroller array. So basically, this "touchable image-looking bar button item" will only appear in the navigation bar when this view controller when it's being shown. When you push another view controller, this navigation bar button item will disappear.
You can also harness the __new__ method to your advantage. You just forgot something. The __new__ method always returns the new object so you must return its superclass' new method. Do as follows.
class F:
def __new__(cls):
if cls is F:
raise TypeError("Cannot create an instance of abstract class '{}'".format(cls.__name__))
return super().__new__(cls)
When using the new method, you have to return the object, not the None keyword. That's all you missed.
If you want query parameters, you use @QueryParam
.
public Todo getXML(@QueryParam("summary") String x,
@QueryParam("description") String y)
But you won't be able to send a PUT from a plain web browser (today). If you type in the URL directly, it will be a GET.
Philosophically, this looks like it should be a POST, though. In REST, you typically either POST to a common resource, /todo
, where that resource creates and returns a new resource, or you PUT to a specifically-identified resource, like /todo/<id>
, for creation and/or update.
Assuming that you didn't set a precision initially, it's assumed to be the maximum (38). You're reducing the precision because you're changing it from 38 to 14.
The easiest way to handle this is to rename the column, copy the data over, then drop the original column:
alter table EVAPP_FEES rename column AMOUNT to AMOUNT_OLD;
alter table EVAPP_FEES add AMOUNT NUMBER(14,2);
update EVAPP_FEES set AMOUNT = AMOUNT_OLD;
alter table EVAPP_FEES drop column AMOUNT_OLD;
If you really want to retain the column ordering, you can move the data twice instead:
alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);
update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;
update EVAPP_FEES set AMOUNT = null;
alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);
update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;
alter table EVAPP_FEES drop column AMOUNT_TEMP;
Try this query:
DELETE WorkRecord2, Employee
FROM WorkRecord2
INNER JOIN Employee ON (tbl_name.EmployeeRun=tbl_name.EmployeeNo)
WHERE tbl_name.Company = '1'
AND tbl_name.Date = '2013-05-06';
One sentence solution: Use padding transition. It's enough for most of cases such as accordion, and even better because it's fast due to that the padding value is often not big.
If you want the animation process to be better, just raise the padding value.

The permanent space is where the classes, methods, internalized strings, and similar objects used by the VM are stored and never deallocated (hence the name).
This Oracle article succinctly presents the working and parameterization of the HotSpot GC and advises you to augment this space if you load many classes (this is typically the case for application servers and some IDE like Eclipse) :
The permanent generation does not have a noticeable impact on garbage collector performance for most applications. However, some applications dynamically generate and load many classes; for example, some implementations of JavaServer Pages (JSP) pages. These applications may need a larger permanent generation to hold the additional classes. If so, the maximum permanent generation size can be increased with the command-line option -XX:MaxPermSize=.
Note that this other Oracle documentation lists the other HotSpot arguments.
Update : Starting with Java 8, both the permgen space and this setting are gone. The memory model used for loaded classes and methods is different and isn't limited (with default settings). You should not see this error any more.
Python has a min()

>>> min(darr)
-2.71828
ORDER BY column OFFSET 0 ROWS
Surprisingly makes it work, what a strange feature.
A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:
;WITH cte AS (
SELECT .....long select statement here....
)
SELECT * FROM
(
SELECT * FROM
( -- necessary to nest selects for union to work with where & order clauses
SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS
) first
UNION ALL
SELECT * FROM
(
SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS
) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example
So we get all results ordered by MainCol
But the results with MainCol = 1
get ordered by ColX
And the results with MainCol = 0
get ordered by ColY
Build the virtual columns(like RowID in Oracle)
Table:

insert into stack values(2007,'p02',3.3);
insert into stack values(2003,'p01',7.4);
insert into stack values(2008,'p01',6.8);
SQL like this:

from (select t1.*, (select count(*) from stack t2 where t1.rate<=t2.rate and t1.id=t2.id) as rownum from stack t1) t3
where rownum <=3 order by id,rate DESC;
If delete the where clause in t3, it shows like this:
GET "TOP N Record" --> add the rownum <=3
in where
clause (the where-clause of t3);
CHOOSE "the year" --> add the BETWEEN 2000 AND 2009
in where
clause (the where-clause of t3);

!!!You must always use HTTPS
for your networking stuff. But if you really can't, just add an exception to the info.plist
For example, if you are using http://google.com
and getting that error, You MUST change it to https://google.com
(with s) since it supports perfectly.
But if you can't somehow, (and you cant convince backend developers to support SSL), add JUST this unsecured domain to the info.plist
(instead of making it available for ALL UNSECURE NET!)

Dependencies
Put the following lines in your gradle (app) file. Jackson is optional. You can use it for object serialization and deserialization.
implementation 'com.squareup.okhttp3:okhttp:4.3.1'
implementation 'com.fasterxml.jackson.core:jackson-core:2.9.8'
implementation 'com.fasterxml.jackson.core:jackson-annotations:2.9.8'
implementation 'com.fasterxml.jackson.core:jackson-databind:2.9.8'
BEGIN
FOR r IN (select sid,serial# from v$session where username='user')
LOOP
EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid || ','
|| r.serial# || ''' immediate';
END LOOP;
END;
This should work - I just changed your script to add the immediate
keyword. As the previous answers pointed out, the kill session
only marks the sessions for killing; it does not do so immediately but later when convenient.
From your question, it seemed you are expecting to see the result immediately. So immediate
keyword is used to force this.
Spring lets you define multiple contexts in a parent-child hierarchy.
The applicationContext.xml
defines the beans for the "root webapp context", i.e. the context associated with the webapp.
The spring-servlet.xml
(or whatever else you call it) defines the beans for one servlet's app context. There can be many of these in a webapp, one per Spring servlet (e.g. spring1-servlet.xml
for servlet spring1
, spring2-servlet.xml
for servlet spring2
).
Beans in spring-servlet.xml
can reference beans in applicationContext.xml
, but not vice versa.
All Spring MVC controllers must go in the spring-servlet.xml
context.
In most simple cases, the applicationContext.xml
context is unnecessary. It is generally used to contain beans that are shared between all servlets in a webapp. If you only have one servlet, then there's not really much point, unless you have a specific use for it.

It could be that the npm registry was down at the time or your connection dropped.
Either way you should upgrade node and npm.
I would recommend using nave to manage your node environments.
https://npmjs.org/package/nave
It allows you to easily install versions and quickly jump between them.
You can always do:
for k in sorted(d.keys()):
print d[k]
This will give you a consistently sorted (with respect to builtin.hash() I guess) set of keys you can process on if the sorting has any meaning to you. That means for example numeric types are sorted consistently even if you expand the dictionary.
EXAMPLE
# lets create a simple dictionary
d = {1:1, 2:2, 3:3, 4:4, 10:10, 100:100}
print d.keys()
print sorted(d.keys())
# add some other stuff
d['peter'] = 'peter'
d['parker'] = 'parker'
print d.keys()
print sorted(d.keys())
# some more stuff, numeric of different type, this will "mess up" the keys set order
d[0.001] = 0.001
d[3.14] = 'pie'
d[2.71] = 'apple pie'
print d.keys()
print sorted(d.keys())
Note that the dictionary is sorted when printed. But the key set is essentially a hashmap!
According to the java.io.File
Java Docs
The default temporary-file directory is specified by the system property java.io.tmpdir. On UNIX systems the default value of this property is typically "/tmp" or "/var/tmp"; on Microsoft Windows systems it is typically "c:\temp". A different value may be given to this system property when the Java virtual machine is invoked, but programmatic changes to this property are not guaranteed to have any effect upon the the temporary directory used by this method.
To specify the java.io.tmpdir
System property, you can invoke the JVM as follows:
java -Djava.io.tmpdir=/path/to/tmpdir
By default this value should come from the TMP
environment variable on Windows systems
_WIN32 identifier is not defined.
use #include <SDKDDKVer.h>
MSVS generated projects wrap this include by generating a local "targetver.h"
which is included by "stdafx.h"
that is comiled into a precompiled-header through "stdafx.cpp"
.
EDIT : do you have a /D "WIN32" on your commandline ?
The code you wrote will always return true
because state
cannot be both 10 and 15 for the statement to be false. if ((state != 10) && (state != 15)....
AND
is what you need not OR
.
Use $.inArray instead. This returns the index of the element in the array.
var statesArray = [10, 15, 19]; // list out all
var index = $.inArray(state, statesArray);
if(index == -1) {
console.log("Not there in array");
return true;
} else {
console.log("Found it");
return false;
}
Postgres has few types of timestamps:
timestamp without timezone - (Preferable to store UTC timestamps) You find it in multinational database storage. The client in this case will take care of the timezone offset for each country.
timestamp with timezone - The timezone offset is already included in the timestamp.
In some cases, your database does not use the timezone but you still need to group records in respect with local timezone and Daylight Saving Time (e.g. https://www.timeanddate.com/time/zone/romania/bucharest)
To add timezone you can use this example and replace the timezone offset with yours.
"your_date_column" at time zone '+03'
To add the +1 Summer Time offset specific to DST you need to check if your timestamp falls into a Summer DST. As those intervals varies with 1 or 2 days, I will use an aproximation that does not affect the end of month records, so in this case i can ignore each year exact interval.
If more precise query has to be build, then you have to add conditions to create more cases. But roughly, this will work fine in splitting data per month in respect with timezone and SummerTime when you find timestamp without timezone in your database:
SELECT
"id", "Product", "Sale",
date_trunc('month',
CASE WHEN
Extract(month from t."date") > 03 AND
Extract(day from t."date") > 26 AND
Extract(hour from t."date") > 3 AND
Extract(month from t."date") < 10 AND
Extract(day from t."date") < 29 AND
Extract(hour from t."date") < 4
THEN
t."date" at time zone '+03' -- Romania TimeZone offset + DST
ELSE
t."date" at time zone '+02' -- Romania TimeZone offset
END) as "date"
FROM
public."Table" AS t
WHERE 1=1
AND t."date" >= '01/07/2015 00:00:00'::TIMESTAMP WITHOUT TIME ZONE
AND t."date" < '01/07/2017 00:00:00'::TIMESTAMP WITHOUT TIME ZONE
GROUP BY date_trunc('month',
CASE WHEN
Extract(month from t."date") > 03 AND
Extract(day from t."date") > 26 AND
Extract(hour from t."date") > 3 AND
Extract(month from t."date") < 10 AND
Extract(day from t."date") < 29 AND
Extract(hour from t."date") < 4
THEN
t."date" at time zone '+03' -- Romania TimeZone offset + DST
ELSE
t."date" at time zone '+02' -- Romania TimeZone offset
END)
You can do it by not initializing url and writing it at hardcode like this
//var url = '@Url.Action("ActionName", "Controller");
$.post("/Controller/ActionName?para1=" + data + "¶2=" + data2, function (result) {
$("#" + data).html(result);
............. Your code
});
While your controller side code must be like this below:
public ActionResult ActionName(string para1, string para2)
{
Your Code .......
}
this was simple way. now we can do pass multiple data by json also like this:
var val1= $('#btn1').val();
var val2= $('#btn2').val();
$.ajax({
type: "GET",
url: '@Url.Action("Actionre", "Contr")',
contentType: "application/json; charset=utf-8",
data: { 'para1': val1, 'para2': val2 },
dataType: "json",
success: function (cities) {
ur code.....
}
});
While your controller side code will be same:
public ActionResult ActionName(string para1, string para2)
{
Your Code .......
}
you can simply escape & by following a dot. try this:
INSERT INTO STUDENT(name, class_id) VALUES ('Samantha', 'Java_22 &. Oracle_14');
Do this:
<input type="button" name="test" id="test" value="RUN" /><br/>
<?php
function testfun()
{
echo "Your test function on button click is working";
}
if(array_key_exists('test',$_POST)){
testfun();
}
?>

Create SetTime class:
class SetTime implements OnFocusChangeListener, OnTimeSetListener {
private EditText editText;
private Calendar myCalendar;
public SetTime(EditText editText, Context ctx){
this.editText = editText;
this.editText.setOnFocusChangeListener(this);
this.myCalendar = Calendar.getInstance();
}
@Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
if(hasFocus){
int hour = myCalendar.get(Calendar.HOUR_OF_DAY);
int minute = myCalendar.get(Calendar.MINUTE);
new TimePickerDialog(ctx, this, hour, minute, true).show();
}
}
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
this.editText.setText( hourOfDay + ":" + minute);
}
}
Then call it from onCreate function:
EditText editTextFromTime = (EditText) findViewById(R.id.editTextFromTime);
SetTime fromTime = new SetTime(editTextFromTime, this);

1D array of primitives does copy elements when it is cloned. This tempts us to clone 2D array(Array of Arrays).
Remember that 2D array clone doesn't work due to shallow copy implementation of clone()
.
public static void main(String[] args) {
int row1[] = {0,1,2,3};
int row2[] = row1.clone();
row2[0] = 10;
System.out.println(row1[0] == row2[0]); // prints false
int table1[][]={{0,1,2,3},{11,12,13,14}};
int table2[][] = table1.clone();
table2[0][0] = 100;
System.out.println(table1[0][0] == table2[0][0]); //prints true
}

I stumbled across this question while looking for a way to filter certain elements out of a stream and log them as errors. So I did not really need to split the stream so much as attach a premature terminating action to a predicate with unobtrusive syntax. This is what I came up with:
public class MyProcess {
/* Return a Predicate that performs a bail-out action on non-matching items. */
private static <T> Predicate<T> withAltAction(Predicate<T> pred, Consumer<T> altAction) {
return x -> {
if (pred.test(x)) {
return true;
}
altAction.accept(x);
return false;
};
/* Example usage in non-trivial pipeline */
public void processItems(Stream<Item> stream) {
stream.filter(Objects::nonNull)
.peek(this::logItem)
.map(Item::getSubItems)
.filter(withAltAction(SubItem::isValid,
i -> logError(i, "Invalid")))
.peek(this::logSubItem)
.filter(withAltAction(i -> i.size() > 10,
i -> logError(i, "Too large")))
.map(SubItem::toDisplayItem)
.forEach(this::display);
}
}
@angular/material
has changed its folder structure. Now you need to use all the modules from their respective folders instead of just material
folder
For example:
import { MatDialogModule } from "@angular/material";
has now changed to
import { MatDialogModule } from "@angular/material/dialog";
You can check the following to find the correct path for your module
https://material.angular.io/components/categories
Just navigate to the API tab of required module and find the correct path like this
Mike, I had the same problem with SSIS in SQL Server 2005... Apparently, the DataFlowDestination object will always attempt to validate the data coming in, into Unicode. Go to that object, Advanced Editor, Component Properties pane, change the "ValidateExternalMetaData" property to False. Now, go to the Input and Output Properties pane, Destination Input, External Columns - set each column Data type and Length to match the database table it's going to. Now, when you close that editor, those column changes will be saved and not validated over, and it will work.
To be honest I have to add my 2 cents.
You can do it with msbuild.exe. There are many version of the msbuild.exe.
C:\Windows\Microsoft.NET\Framework64\v2.0.50727\msbuild.exe C:\Windows\Microsoft.NET\Framework64\v3.5\msbuild.exe C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild.exe
C:\Windows\Microsoft.NET\Framework\v2.0.50727\msbuild.exe C:\Windows\Microsoft.NET\Framework\v3.5\msbuild.exe C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe
Use version you need. Basically you have to use the last one.
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild.exe
So how to do it.
Run the COMMAND window
Input the path to msbuild.exe
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild.exe
"C:\Users\Clark.Kent\Documents\visual studio 2012\Projects\WpfApplication1\WpfApplication1.sln"
Add any flags you need after the solution path.
Press ENTER
Note you can get help about all possible flags like

For basic cleanup and re-analyzing you can run "OPTIMIZE TABLE ...", it will compact out the overhead in the indexes and run ANALYZE TABLE too, but it's not going to re-sort them and make them as small & efficient as they could be.
https://dev.mysql.com/doc/refman/8.0/en/optimize-table.html
However, if you want the indexes completely rebuilt for best performance, you can:
https://dev.mysql.com/doc/refman/8.0/en/rebuilding-tables.html
If you do an ALTER TABLE on a field (that is part of an index) and change its type, then it will also fully rebuild the related index(es).
Generally you should also override hashCode()
each time you override equals()
, even if just for the performance boost. HashCode()
decides which 'bucket' your object gets sorted into when doing a comparison, so any two objects which equal()
evaluates to true should return the same hashCode
value()
. I cannot remember the default behavior of hashCode()
(if it returns 0 then your code should work but slowly, but if it returns the address then your code will fail). I do remember a bunch of times when my code failed because I forgot to override hashCode()
though. :)
Try doing it in viewDidLoad. Generally you should defer anything you can until that point anyway, when a UIViewController is inited it still might be quite a while before it displays, no point in doing work early and tying up memory.
- (void)viewDidLoad {
[super viewDidLoad];
UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Show" style:UIBarButtonItemStylePlain target:self action:@selector(refreshPropertyList:)];
self.navigationItem.rightBarButtonItem = anotherButton;
// exclude the following in ARC projects...
[anotherButton release];
}
As to why it isn't working currently, I can't say with 100% certainty without seeing more code, but a lot of stuff happens between init and the view loading, and you may be doing something that causes the navigationItem to reset in between.
Full reference for next button and progress bar : put back and next button in webview
If you want to go to back page when click on phone's back button, use this:
@Override
public void onBackPressed() {
if (webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}
You can also create custom back button like this:
btnback.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (wv.canGoBack()) {
wv.goBack();
}
}
});
you can try this code to capture a div When the div is very wide or offset relative to the screen
var div = $("#div")[0];
var rect = div.getBoundingClientRect();
var canvas = document.createElement("canvas");
canvas.width = rect.width;
canvas.height = rect.height;
var ctx = canvas.getContext("2d");
ctx.translate(-rect.left,-rect.top);
html2canvas(div, {
canvas:canvas,
height:rect.height,
width:rect.width,
onrendered: function(canvas) {
var image = canvas.toDataURL("image/png");
var pHtml = "<img src="+image+" />";
$("#parent").append(pHtml);
}
});
With:
global index_add_counter
You are not defining, just declaring so it's like saying there is a global index_add_counter
variable elsewhere, and not create a global called index_add_counter
. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global
keyword and initialize your variable:
index_add_counter = 0
Now you can import it with:
from app import index_add_counter
The construction:
global index_add_counter
is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:
index_add_counter = 0
def test():
global index_add_counter # means: in this scope, use the global name
print(index_add_counter)
I wrote a wrapper, that will cache text surfaces, only re-render when dirty. googlecode/ninmonkey/nin.text/demo/
For situations like this, i like to make a deep copy and loop through that copy while modifying the original dict.
If the lookup field is within a list, you can enumerate in the for loop of the list and then specify the position as index to access the field in the original dict.
You need to either convert each table individually:
ALTER TABLE mytable CONVERT TO CHARACTER SET utf8mb4
(this will convert the columns just as well), or export the database with latin1
and import it back with utf8mb4
.
Based on HTML 4, the id should start from letter:
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").
So, one of the solutions could be (alphanumeric):
var length = 9;
var prefix = 'my-awesome-prefix-'; // To be 100% sure id starts with letter
// Convert it to base 36 (numbers + letters), and grab the first 9 characters
// after the decimal.
var id = prefix + Math.random().toString(36).substr(2, length);
Another solution - generate string with letters only:
var length = 9;
var id = Math.random().toString(36).replace(/[^a-z]+/g, '').substr(0, length);
I have "experienced" this error on Windows because my name (and hence %HOMEPATH%
) contains a non ascii character (é
). Either git or cmd.exe or anything else could not cope with this.
I too always use a numeric ID column. In oracle I use number(18,0) for no real reason above number(12,0) (or whatever is an int rather than a long), maybe I just don't want to ever worry about getting a few billion rows in the db!
I also include a created and modified column (type timestamp) for basic tracking, where it seems useful.
I don't mind setting up unique constraints on other combinations of columns, but I really like my id, created, modified baseline requirements.
It looks like the Django REST framework uses the HTTP accept header in a Request in order to automatically determine which renderer to use:
http://www.django-rest-framework.org/api-guide/renderers/
Using the HTTP accept header may provide an alternative source for your "if something".
In x0n's example, it should be:
SET ROWCOUNT @top
SELECT * from sometable
SET ROWCOUNT 0
That’s a media query. It prevents the CSS inside it from being run unless the browser passes the tests it contains.
The tests in this media query are:
@media screen
— The browser identifies itself as being in the “screen” category. This roughly means the browser considers itself desktop-class — as opposed to e.g. an older mobile phone browser (note that the iPhone, and other smartphone browsers, do identify themselves as being in the screen category), or a screenreader — and that it’s displaying the page on-screen, rather than printing it.
max-width: 1024px
— the width of the browser window (including the scroll bar) is 1024 pixels or less. (CSS pixels, not device pixels.)
That second test suggests this is intended to limit the CSS to the iPad, iPhone, and similar devices (because some older browsers don’t support max-width
in media queries, and a lot of desktop browsers are run wider than 1024 pixels).
However, it will also apply to desktop browser windows less than 1024 pixels wide, in browsers that support the max-width
media query.
Here’s the Media Queries spec, it’s pretty readable:
Or you can just use <input onclick="select()">
Works perfect.
Split (",") can convert Strings with commas into a String array, here is my code snippet.
var input ='Hybrid App, Phone-Gap, Apache Cordova, HTML5, JavaScript, BootStrap, JQuery, CSS3, Android Wear API'
var output = input.split(",");
console.log(output);
["Hybrid App", " Phone-Gap", " Apache Cordova", " HTML5", " JavaScript", " BootStrap", " JQuery", " CSS3", " Android Wear API"]
You should use the grep
-q
flag for quiet output. See the man pages below:
man grep output :
General Output Control
-q, --quiet, --silent
Quiet; do not write anything to standard output. Exit immediately with zero status
if any match is found, even if an error was detected. Also see the -s or
--no-messages option. (-q is specified by POSIX.)
This KornShell (ksh) script demos the grep
quiet output and is a solution to your question.

In my setting.gradle, I included a module that does not exist. Once I removed it, it started working. This could be another way to fix this issue
To do this job in storyboard (Interface Builder Inspector)
With help of IBDesignable
, we can add more options to Interface Builder Inspector for UIButton
and tweak them on storyboard. First, add the following code to your project.
@IBDesignable extension UIButton {
@IBInspectable var borderWidth: CGFloat {
set {
layer.borderWidth = newValue
}
get {
return layer.borderWidth
}
}
@IBInspectable var cornerRadius: CGFloat {
set {
layer.cornerRadius = newValue
}
get {
return layer.cornerRadius
}
}
@IBInspectable var borderColor: UIColor? {
set {
guard let uiColor = newValue else { return }
layer.borderColor = uiColor.cgColor
}
get {
guard let color = layer.borderColor else { return nil }
return UIColor(cgColor: color)
}
}
}
Then simply set the attributes for buttons on storyboard.
In any case you can know it:
mysql> select @@datadir;
+----------------------------------------------------------------+
| @@datadir |
+----------------------------------------------------------------+
| D:\Documents and Settings\b394382\My Documents\MySQL_5_1\data\ |
+----------------------------------------------------------------+

Create a role add this role to users, and then you can grant execute to all the routines in one shot to this role.
CREATE ROLE <abc>
GRANT EXECUTE TO <abc>
EDIT
This works in SQL Server 2005, I'm not sure about backward compatibility of this feature, I'm sure anything later than 2005 should be fine.
Just try to remove clear:both
property from the div
with class
sample
and see how it follows floating divs
.
int randomWithRange(int min, int max)
{
int range = (max - min) + 1;
return (int)(Math.random() * range) + min;
}
Output of randomWithRange(2, 5)
10 times:
5
2
3
3
2
4
4
4
5
4
The bounds are inclusive, ie [2,5], and min
must be less than max
in the above example.
EDIT: If someone was going to try and be stupid and reverse min
and max
, you could change the code to:
int randomWithRange(int min, int max)
{
int range = Math.abs(max - min) + 1;
return (int)(Math.random() * range) + (min <= max ? min : max);
}
EDIT2: For your question about double
s, it's just:
double randomWithRange(double min, double max)
{
double range = (max - min);
return (Math.random() * range) + min;
}
And again if you want to idiot-proof it it's just:
double randomWithRange(double min, double max)
{
double range = Math.abs(max - min);
return (Math.random() * range) + (min <= max ? min : max);
}
1.First add this js file to your HTML.
<script th:src="@{${webLinkFactory.jsLibRootPath()}+'/bootstrap-datepicker.nl.min.js'}" charset="UTF-8"type="text/javascript"></script>
obviously after moment.min.js.
content of bootstrap-datepicker.nl.min.js will be
;(function($){
$.fn.datepicker.dates['nl'] = {
days: ["Zondag", "Maandag", "Dinsdag", "Woensdag", "Donderdag", "Vrijdag", "Zaterdag", "Zondag"],
daysShort: ["Zon", "Man", "Din", "Woe", "Don", "Vri", "Zat", "Zon"],
daysMin: ["Zo", "Ma", "Di", "Wo", "Do", "Vr", "Za", "Zo"],
months: ["Januari", "Februari", "Maart", "April", "Mei", "Juni", "Juli", "Augustus", "September", "Oktober", "November", "December"],
monthsShort: ["Jan", "Feb", "Mrt", "Apr", "Mei", "Jun", "Jul", "Aug", "Sep", "Okt", "Nov", "Dec"],
today: "Vandaag",
suffix: [],
meridiem: []
};
$.fn.datetimepicker.dates['nl'] = {
days: ["Zondag", "Maandag", "Dinsdag", "Woensdag", "Donderdag", "Vrijdag", "Zaterdag", "Zondag"],
daysShort: ["Zon", "Man", "Din", "Woe", "Don", "Vri", "Zat", "Zon"],
daysMin: ["Zo", "Ma", "Di", "Wo", "Do", "Vr", "Za", "Zo"],
months: ["Januari", "Februari", "Maart", "April", "Mei", "Juni", "Juli", "Augustus", "September", "Oktober", "November", "December"],
monthsShort: ["Jan", "Feb", "Mrt", "Apr", "Mei", "Jun", "Jul", "Aug", "Sep", "Okt", "Nov", "Dec"],
today: "Vandaag",
suffix: [],
meridiem: []
};
}(jQuery));
2.set this line in the ready function of your js file.
$(document).ready(function () {
$.fn.datetimepicker.defaults.language = 'nl';
}
3.initialize your datetimepicker in this way
$(this).datetimepicker({
format: "yyyy-mm-dd hh:ii",
autoclose: true,
weekStart: 1,
locale: 'nl',
language: 'nl'
});
following this steps i was able to convert my english datepicker and datetimepicker to dutch successfully.
Make Theme.AppCompat style parent
<style name="AppTheme" parent="Theme.AppCompat">
<item name="android:colorPrimary">#005555</item>
<item name="android:colorPrimaryDark">#003333</item>
</style>
And put getSupportActionBar().getThemedContext()
in onCreate()
.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
getSupportActionBar().getThemedContext();
}
std::queue<myclass*> my_queue;
will do the job.
See here for more information on this container.
Perl Code for Unix systems:
# Capture date from shell
my $current_date = `date +"%m/%d/%Y"`;
# Remove newline character
$current_date = substr($current_date,0,-1);
print $current_date, "\n";
In my case the issue was caused due to mismatch in .Xauthority file. Which initially showed up with "Invalid MIT-MAGIC-COOKIE-1" error and then "Error: cannot open display: :0.0" afterwards
Regenerating the .Xauthorityfile from the user under which I am running the vncserver and resetting the password with a restart of the vnc service and dbus service fixed the issue for me.
In jquery to replace a class with another you can use jqueryUI SwitchClass option
$("#YourID").switchClass("old-class-here", "new-class-here");
fastest way is to use the .is()
jQuery function.
if ( $('input').is('[readonly]') ) { }
using [readonly]
as a selector simply checks if the attribute is defined on your element. if you want to check for a value, you can use something like this instead:
if ( $('input').is('[readonly="somevalue"]') ) { }
token_type
is a parameter in Access Token generate call to Authorization server, which essentially represents how an access_token will be generated and presented for resource access calls.
You provide token_type in the access token generation call to an authorization server.
If you choose Bearer
(default on most implementation), an access_token
is generated and sent back to you. Bearer can be simply understood as "give access to the bearer of this token." One valid token and no question asked. On the other hand, if you choose Mac
and sign_type
(default hmac-sha-1
on most implementation), the access token is generated and kept as secret in Key Manager as an attribute, and an encrypted secret is sent back as access_token
.
Yes, you can use your own implementation of token_type
, but that might not make much sense as developers will need to follow your process rather than standard implementations of OAuth.
