As of December 2017, there have been some updates, e.g. the usage of android.hardware.Camera
is deprecated now. While the newer android.hardware.camera2
comes with handy things like a CameraManager
.
I personally like this example a lot, which makes use of this current API and works like a charm: https://github.com/googlesamples/android-Camera2Video
It also includes asking the user for the required permissions at start and features video preview before starting the video recording.
(In addition, I find the code really beautiful (and this is very rare for me ^^), but that's just my subjective opinion.)
I just had a related problem (which is how I found this thread), where my dynamically added row and column styles were not taking effect. I usually consider SuspendLayout()/ResumeLayout() as optimizations, but in this case, wrapping my code in them made the rows and columns behave correctly.
You can first concatenate the strings in the list with the separator ';' using the function join
and then use the split
function in order create the list:
l = ['Facebook;Google+;MySpace', 'Apple;Android']
l1 = ";".join(l)).split(";")
print l1
outputs
['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']
setserial with the -g option appears to do what you want and the C source is available at http://www.koders.com/c/fid39344DABD14604E70DF1B8FEA7D920A94AF78BF8.aspx.
You could use

<title>Two Colors</title>
<style type="text/css">
.two-colors {

I assume you are using the caption feature of Word, that is, captions were not typed in as normal text, but were inserted using Insert > Caption (Word versions before 2007), or References > Insert Caption (in the ribbon of Word 2007 and up). If done correctly, the captions are really 'fields'. You'll know if it is a field if the caption's background turns grey when you put your cursor on them (or is permanently displayed grey).
Captions are fields - Unfortunately fields (like caption fields) are only updated on specific actions, like opening of the document, printing, switching from print view to normal view, etc. The easiest way to force updating of all (caption) fields when you want it is by doing the following:
Captions are normal text - If the caption number is not a field, I am afraid you'll have to edit the text manually.
This function tells the entity referenced by REF that it is now an object in the CLASSNAME package, or the current package if CLASSNAME is omitted. Use of the two-argument form of bless is recommended.
Example:
bless REF, CLASSNAME
bless REF
Return Value
This function returns the reference to an object blessed into CLASSNAME.
Example:
Following is the example code showing its basic usage, the object reference is created by blessing a reference to the package's class -
#!/usr/bin/perl
package Person;
sub new
{
my $class = shift;
my $self = {
_firstName => shift,
_lastName => shift,
_ssn => shift,
};
# Print all the values just for clarification.
print "First Name is $self->{_firstName}\n";
print "Last Name is $self->{_lastName}\n";
print "SSN is $self->{_ssn}\n";
bless $self, $class;
return $self;
}
package main
import "fmt"
import "strconv"
func FloatToString(input_num float64) string {
// to convert a float number to a string
return strconv.FormatFloat(input_num, 'f', 6, 64)
}
func main() {
fmt.Println(FloatToString(21312421.213123))
}
If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg
strconv.FormatFloat(input_num, 'f', -1, 64)
Personally I find fmt
easier to use. (Playground link)
fmt.Printf("x = %.6f\n", 21312421.213123)
Or if you just want to convert the string
fmt.Sprintf("%.6f", 21312421.213123)
Assuming you want to reset your PostgreSQL database and set it back up, use:
heroku apps
to list your applications on Heroku. Find the name of your current application (application_name
). Then run
heroku config | grep POSTGRESQL
to get the name of your databases. An example could be
HEROKU_POSTGRESQL_WHITE_URL
Finally, given application_name
and database_url
, you should run
heroku pg:reset `database_url` --confirm `application_name`
heroku run rake db:migrate
heroku restart
First of all, it is totally possible to write apps with React without Flux.
Also this visual diagram which I've created to show a quick view of both, probably a quick answer for the people who don't want to read the whole explanation:
But if you still interested knowing more, read on.
I believe you should start with pure React, then learn Redux and Flux. After you will have some REAL experience with React, you will see whether Redux is helpful for you or not.
Maybe you will feel that Redux is exactly for your app and maybe you will find out, that Redux is trying to solve a problem you are not really experiencing.
If you start directly with Redux, you may end up with over-engineered code, code harder to maintain and with even more bugs and than without Redux.
From Redux docs:
Motivation
As the requirements for JavaScript single-page applications have become increasingly complicated, our code must manage more state than ever before. This state can include server responses and cached data, as well as locally created data that has not yet been persisted to the server. UI state is also increasing in complexity, as we need to manage active routes, selected tabs, spinners, pagination controls, and so on.Managing this ever-changing state is hard. If a model can update another model, then a view can update a model, which updates another model, and this, in turn, might cause another view to update. At some point, you no longer understand what happens in your app as you have lost control over the when, why, and how of its state. When a system is opaque and non-deterministic, it's hard to reproduce bugs or add new features.
As if this wasn't bad enough, consider the new requirements becoming common in front-end product development. As developers, we are expected to handle optimistic updates, server-side rendering, fetching data before performing route transitions, and so on. We find ourselves trying to manage a complexity that we have never had to deal with before, and we inevitably ask the question: Is it time to give up? The answer is No.
This complexity is difficult to handle as we're mixing two concepts that are very hard for the human mind to reason about: mutation and asynchronicity. I call them Mentos and Coke. Both can be great when separated, but together they create a mess. Libraries like React attempt to solve this problem in the view layer by removing both asynchrony and direct DOM manipulation. However, managing the state of your data is left up to you. This is where Redux comes in.
Following in the footsteps of Flux, CQRS, and Event Sourcing, Redux attempts to make state mutations predictable by imposing certain restrictions on how and when updates can happen. These restrictions are reflected in the three principles of Redux.
Also from Redux docs:
Core Concepts
Redux itself is very simple.Imagine your app's state is described as a plain object. For example, the state of a todo app might look like this:
{ todos: [{ text: 'Eat food', completed: true }, { text: 'Exercise', completed: false }], visibilityFilter: 'SHOW_COMPLETED' }
This object is like a "model" except that there are no setters. This is so that different parts of the code can’t change the state arbitrarily, causing hard-to-reproduce bugs.
To change something in the state, you need to dispatch an action. An action is a plain JavaScript object (notice how we don't introduce any magic?) that describes what happened. Here are a few example actions:
{ type: 'ADD_TODO', text: 'Go to swimming pool' } { type: 'TOGGLE_TODO', index: 1 } { type: 'SET_VISIBILITY_FILTER', filter: 'SHOW_ALL' }
Enforcing that every change is described as an action lets us have a clear understanding of what’s going on in the app. If something changed, we know why it changed. Actions are like breadcrumbs of what has happened. Finally, to tie state and actions together, we write a function called a reducer. Again, nothing magic about it — it's just a function that takes state and action as arguments, and returns the next state of the app. It would be hard to write such a function for a big app, so we write smaller functions managing parts of the state:
function visibilityFilter(state = 'SHOW_ALL', action) { if (action.type === 'SET_VISIBILITY_FILTER') { return action.filter; } else { return state; } } function todos(state = [], action) { switch (action.type) { case 'ADD_TODO': return state.concat([{ text: action.text, completed: false }]); case 'TOGGLE_TODO': return state.map((todo, index) => action.index === index ? { text: todo.text, completed: !todo.completed } : todo ) default: return state; } }
And we write another reducer that manages the complete state of our app by calling those two reducers for the corresponding state keys:
function todoApp(state = {}, action) { return { todos: todos(state.todos, action), visibilityFilter: visibilityFilter(state.visibilityFilter, action) }; }
This is basically the whole idea of Redux. Note that we haven't used any Redux APIs. It comes with a few utilities to facilitate this pattern, but the main idea is that you describe how your state is updated over time in response to action objects, and 90% of the code you write is just plain JavaScript, with no use of Redux itself, its APIs, or any magic.
You can not use argv[0] for that purpose, usually it does contain full path to the executable, but not nessesarily - process could be created with arbitrary value in the field.
Also mind you, the current directory and the directory with the executable are two different things, so getcwd() won't help you either.
On Windows use GetModuleFileName(), on Linux read /dev/proc/procID/.. files.
Fill the entire screen
var body : some View{
Color.green.edgesIgnoringSafeArea(.all)
}
You can try the following line of code
$result = $data1." ".$data2;
Syntax is as same as of class in C++. If you aware of creating constructor in c++ then it is same in struct.
struct Date
{
int day;
Date(int d)
{
day = d;
}
void printDay()
{
cout << "day " << day << endl;
}
};
Struct can have all things as class in c++. As earlier said difference is only that by default C++ member have private access but in struct it is public.But as per programming consideration Use the struct keyword for data-only structures. Use the class keyword for objects that have both data and functions.
Additional thoughts :
Ramdisk - setting the temp drive MySQL uses as a RAM disk, very easy to set up.
memcache - memcache server is easy to set up, use it to store the results of your queries for X amount of time.
simple google search came up with this. Doubt anyone can explain this any simpler. But I guess after an edit, I can try to bring forward the concepts so that you can answer your own question.
Hint :
Study for exam, hard, you must. Predict you, grade get high, I do :D
Explanation :
It's all about the way operations are associated with operands. each notation type has its own rules. You just need to break down and remember these rules. If I told you I wrote (2*2)/3 as [* /] (2,2,3) all you need to do is learn how to turn the latter notation in the former notation.
My custom notation says that take the first two operands and multiple them, then the resulting operand should be divided by the third. Get it ? They are trying to teach you three things.
from decimal import Decimal
def round_float(v, ndigits=2, rt_str=False):
d = Decimal(v)
v_str = ("{0:.%sf}" % ndigits).format(round(d, ndigits))
if rt_str:
return v_str
return Decimal(v_str)
Results:
Python 3.6.1 (default, Dec 11 2018, 17:41:10)
>>> round_float(3.1415926)
Decimal('3.14')
>>> round_float(3.1445926)
Decimal('3.14')
>>> round_float(3.1455926)
Decimal('3.15')
>>> round_float(3.1455926, rt_str=True)
'3.15'
>>> str(round_float(3.1455926))
'3.15'
Two solutions for this:
PHP function nl2br()
:
e.g.,
echo nl2br("This\r\nis\n\ra\nstring\r");
// will output
This<br />
is<br />
a<br />
string<br />
Wrap the input in <pre></pre>
tags.

I've heard about some projects that directly compile IL into native code. You can get some additional info from this post: Is it possible to compile .NET IL code to machine code?
For Rails5 models are now subclasses of ApplicationRecord
so to get list of all models in your app you do:
ApplicationRecord.descendants.collect { |type| type.name }
Or shorter:
ApplicationRecord.descendants.collect(&:name)
If you are in dev mode, you will need to eager load models before:
Rails.application.eager_load!
Latest and greatest way to do this:
Node supports file and buffer operations with the base64
encoding:
const fs = require('fs');
const contents = fs.readFileSync('/path/to/file.jpg', {encoding: 'base64'});
Or using the new promises API:
const fs = require('fs').promises;
const contents = await fs.readFile('/path/to/file.jpg', {encoding: 'base64'});
I suspect you are having a problem with factors. For example,
> x = factor(4:8)
> x
[1] 4 5 6 7 8
Levels: 4 5 6 7 8
> as.numeric(x)
[1] 1 2 3 4 5
> as.numeric(as.character(x))
[1] 4 5 6 7 8
Some comments:
as.numeric
to do with these values?read.csv
, try using the argument stringsAsFactors=FALSE
sep="/t
and not sep="\t"
head(pitchman)
to check the first fews rows of your datapichman <- read.csv(file="picman.txt", header=TRUE, sep="/t")
since I don't have access to the data set.NOTE: Pure Swift 3 (Xcode 8) example:
Please try out the following sample code. It is the simple example of dataTask
function of URLSession
.
func simpleDataRequest() {
//Get the url from url string
let url:URL = URL(string: "YOUR URL STRING")!
//Get the session instance
let session = URLSession.shared
//Create Mutable url request
var request = URLRequest(url: url as URL)
//Set the http method type
request.httpMethod = "POST"
//Set the cache policy
request.cachePolicy = URLRequest.CachePolicy.reloadIgnoringCacheData
//Post parameter
let paramString = "key=value"
//Set the post param as the request body
request.httpBody = paramString.data(using: String.Encoding.utf8)
let task = session.dataTask(with: request as URLRequest) {
(data, response, error) in
guard let _:Data = data as Data?, let _:URLResponse = response , error == nil else {
//Oops! Error occured.
print("error")
return
}
//Get the raw response string
let dataString = String(data: data!, encoding: String.Encoding(rawValue: String.Encoding.utf8.rawValue))
//Print the response
print(dataString!)
}
//resume the task
task.resume()
}
std::ctype::tolower()
from the standard C++ Localization library will correctly do this for you. Here is an example extracted from the tolower reference page
#include <locale>
#include <iostream>
int main () {
std::locale::global(std::locale("en_US.utf8"));
std::wcout.imbue(std::locale());
std::wcout << "In US English UTF-8 locale:\n";
auto& f = std::use_facet<std::ctype<wchar_t>>(std::locale());
std::wstring str = L"HELLo, wORLD!";
std::wcout << "Lowercase form of the string '" << str << "' is ";
f.tolower(&str[0], &str[0] + str.size());
std::wcout << "'" << str << "'\n";
}
I'm very late to this game, but my problem started when I upgraded php on my server. I was able to just remove the .socket file and restart my services. Then, everything worked. Not sure why it made a difference, since the file is size 0 and the ownership and permissions are the same, but it worked.
If you're open to using libraries, try installing forked-path (with either easy_install or pip).
Then you can do:
from path import path
s = path(filename).bytes()
This library is fairly new, but it's a fork of a library that's been floating around Python for years and has been used quite a bit. Since I found this library years ago, I very seldom use os.path
or open()
any more.

Accessing a single row
//Result as an Object
$result = $this->db->select('age')->from('my_users_table')->where('id', '3')->limit(1)->get()->row();
echo $result->age;
//Result as an Array
$result = $this->db->select('age')->from('my_users_table')->where('id', '3')->limit(1)->get()->row_array();
echo $result['age'];
When using WebAPI, you should just return the Object rather than specifically returning Json, as the API will either return JSON or XML depending on the request.
I am not sure why your WebAPI is returning an ActionResult, but I would change the code to something like;
public IEnumerable<ListItems> GetAllNotificationSettings()
{
var result = new List<ListItems>();
// Filling the list with data here...
// Then I return the list
return result;
}
This will result in JSON if you are calling it from some AJAX code.
P.S
WebAPI is supposed to be RESTful, so your Controller should be called ListItemController
and your Method should just be called Get
. But that is for another day.
I'm using svn+ssh protocol to access SVN. What I had to do to fix a similar issue, was to open Putty and reconfigure it so that it did not have wrong_user_name@myserver but correct_user_name@myserver in the saved sessions.
You are passing hello()
as a string, also hello()
means execute hello
immediately.

If you want create a new branch from any of the existing branches in Git, just follow the options.
First change/checkout into the branch from where you want to create a new branch. For example, if you have the following branches like:
So if you want to create a new branch called "subbranch_of_b1" under the branch named "branch1" follow the steps:
Checkout or change into "branch1"
git checkout branch1
Now create your new branch called "subbranch_of_b1" under the "branch1" using the following command.
git checkout -b subbranch_of_b1 branch1
The above will create a new branch called subbranch_of_b1 under the branch branch1 (note that branch1
in the above command isn't mandatory since the HEAD is currently pointing to it, you can precise it if you are on a different branch though).
Now after working with the subbranch_of_b1 you can commit and push or merge it locally or remotely.
push the subbranch_of_b1 to remote
git push origin subbranch_of_b1
I feel like I should add my answer to this because it took me quite long to make this work:
This answer is for you if:
bquote
) in your labels and I basically put the labels in a named vector so labels would not get confused or switched. The labeller
expression could probably be simpler, but this at least works (improvements are very welcome). Note the ` (back quotes) to protect the facet-factor.
n <- 10
x <- seq(0, 300, length.out = n)
# I have my data in a "long" format
my_data <- data.frame(
Type = as.factor(c(rep('dl/l', n), rep('alpha', n))),
T = c(x, x),
Value = c(x*0.1, sqrt(x))
)
# the label names as a named vector
type_names <- c(
`nonsense` = "this is just here because it looks good",
`dl/l` = Linear~Expansion~~Delta*L/L[Ref]~"="~"[%]", # bquote expression
`alpha` = Linear~Expansion~Coefficient~~alpha~"="~"[1/K]"
)
ggplot() +
geom_point(data = my_data, mapping = aes(T, Value)) +
facet_wrap(. ~ Type, scales="free_y",
labeller = label_bquote(.(as.expression(
eval(parse(text = paste0('type_names', '$`', Type, '`')))
)))) +
labs(x="Temperature [K]", y="", colour = "") +
theme(legend.position = 'none')
Using this.props.children
is the idiomatic way to pass instantiated components to a react component
const Label = props => <span>{props.children}</span>
const Tab = props => <div>{props.children}</div>
const Page = () => <Tab><Label>Foo</Label></Tab>
When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose whether that tag is a div
or span
):
const Label = props => <span>{props.children}</span>
const Button = props => {
const Inner = props.inner; // Note: variable name _must_ start with a capital letter
return <button><Inner>Foo</Inner></button>
}
const Page = () => <Button inner={Label}/>
If what you want to do is to pass a children-like parameter as a prop, you can do that:
const Label = props => <span>{props.content}</span>
const Tab = props => <div>{props.content}</div>
const Page = () => <Tab content={<Label content='Foo' />} />
After all, properties in React are just regular JavaScript object properties and can hold any value - be it a string, function or a complex object.
There is another option not mentioned previously:
Eclipse - specific Project change JDK Version -
If you want to change any jdk version of A specific project than you have to click ---> Project --> JRE System Library --> Properties ---> Inside Classpath Container (JRE System Library) change the Execution Environment to which ever version you want e.g. 1.7 or 1.8.
Ruby does have a method for this:
File.readlines('foo').each do |line|
Pandas DatetimeIndex
and Series
have a method called normalize
that does exactly what you want.
You can read more about it in this answer.
It can be used as ser.dt.normalize()
I used java print statements for easy understanding.
To check Element Present:
if(driver.findElements(By.xpath("value")).size() != 0){
System.out.println("Element is Present");
}else{
System.out.println("Element is Absent");
}
Or
if(driver.findElement(By.xpath("value"))!= null){
System.out.println("Element is Present");
}else{
System.out.println("Element is Absent");
}
To check Visible:
if( driver.findElement(By.cssSelector("a > font")).isDisplayed()){
System.out.println("Element is Visible");
}else{
System.out.println("Element is InVisible");
}
To check Enable:
if( driver.findElement(By.cssSelector("a > font")).isEnabled()){
System.out.println("Element is Enable");
}else{
System.out.println("Element is Disabled");
}
To check text present
if(driver.getPageSource().contains("Text to check")){
System.out.println("Text is present");
}else{
System.out.println("Text is absent");
}
To check that the file you're trying to open actually exists, you can change directories in terminal using cd
. To change to ~/Desktop/sass/css
: cd ~/Desktop/sass/css
. To see what files are in the directory: ls
.
If you want information about either of those commands, use the man
page: man cd
or man ls
, for example.
Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.
On Mac OS X, you can also use open
to open a finder window: open .
will open the current directory in finder. (open ~/Desktop/sass/css
will open the ~/Desktop/sass/css
).
There are two different ways of importing components in react and the recommended way is component way
PFB detail explanation
Library way of importing
import { Button } from 'react-bootstrap';
import { FlatButton } from 'material-ui';
This is nice and handy but it does not only bundles Button and FlatButton (and their dependencies) but the whole libraries.
Component way of importing
One way to alleviate it is to try to only import or require what is needed, lets say the component way. Using the same example:
import Button from 'react-bootstrap/lib/Button';
import FlatButton from 'material-ui/lib/flat-button';
This will only bundle Button, FlatButton and their respective dependencies. But not the whole library. So I would try to get rid of all your library imports and use the component way instead.
If you are not using lot of components then it should reduce considerably the size of your bundled file.
I was also having above doubt, what worked for me is
ALTER TABLE `your_table` CHANGE `property` `property`
VARCHAR(whatever_you_want) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL;
sub uniq {
return keys %{{ map { $_ => 1 } @_ }};
}
my @my_array = ("a","a","b","b","c");
#print join(" ", @my_array), "\n";
my $a = join(" ", uniq(@my_array));
my @b = split(/ /,$a);
my $count = $#b;
Primary key fields should be declared as not null (this is non standard as the definition of a primary key is that it must be unique and not null). But below is a good practice for all multi-column primary keys in any DBMS.
create table foo
(
fooint integer not null
,foobar string not null
,fooval real
,primary key (fooint, foobar)
)
;
ROUTER LINK DIRECTIVE:
[routerLink]="link" //when u pass URL value from COMPONENT file
[routerLink]="['link','parameter']" //when you want to pass some parameters along with route
routerLink="link" //when you directly pass some URL
[routerLink]="['link']" //when you directly pass some URL
Since Java 8, there are some standard options to do this in JDK:
Collection<E> in = ...
Object[] mapped = in.stream().map(e -> doMap(e)).toArray();
// or
List<E> mapped = in.stream().map(e -> doMap(e)).collect(Collectors.toList());
See java.util.Collection.stream()
and java.util.stream.Collectors.toList()
.
Python allows for you to multiply sequences to repeat their values. Here is a visual example:
>>> [1] * 5
[1, 1, 1, 1, 1]
But it does not allow you to do it with floating point numbers:
>>> [1] * 5.1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: can't multiply sequence by non-int of type 'float'
@zzzz's answer is mostly complete, but just to save others from having to dig through the referenced documentation you can run a single test in a package as follows:
go test packageName -run TestName
Note that you want to pass in the name of the test, not the file name where the test exists.
The -run
flag actually accepts a regex so you could limit the test run to a class of tests. From the docs:
-run regexp
Run only those tests and examples matching the regular
expression.
The player_api will be deprecated on Jun 25, 2015. For play youtube videos there is a new api IFRAME_API
It looks like the following code:
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>
<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {

If you know the structure of the json that you're receiving then I'd suggest having a class structure that mirrors what you're receiving in json.
Then you can call its something like this...
AddressMap addressMap = JsonConvert.DeserializeObject<AddressMap>(json);
(Where json is a string containing the json in question)
If you don't know the format of the json you've receiving then it gets a bit more complicated and you'd probably need to manually parse it.
check out http://www.hanselman.com/blog/NuGetPackageOfTheWeek4DeserializingJSONWithJsonNET.aspx for more info
You don't need usebackq:
FOR /F delims^= %%A IN ('DIR/AD/B/S^|SORT/R') DO RD "%%A"
Here's a way that doesn't affect your list ordering:
ArrayList l1 = new ArrayList();
ArrayList l2 = new ArrayList();
Iterator iterator = l1.iterator();
while (iterator.hasNext()) {
YourClass o = (YourClass) iterator.next();
if(!l2.contains(o)) l2.add(o);
}
l1 is the original list, and l2 is the list without repeated items (Make sure YourClass has the equals method according to what you want to stand for equality)
If you cannot use apply
for instance if the model does not implement Sequential
directly:
# see UNet at https://github.com/milesial/Pytorch-UNet/tree/master/unet
def init_all(model, init_func, *params, **kwargs):
for p in model.parameters():
init_func(p, *params, **kwargs)
model = UNet(3, 10)
init_all(model, torch.nn.init.normal_, mean=0., std=1)
# or
init_all(model, torch.nn.init.constant_, 1.)
def init_all(model, init_funcs):
for p in model.parameters():
init_func = init_funcs.get(len(p.shape), init_funcs["default"])
init_func(p)
model = UNet(3, 10)
init_funcs = {
1: lambda x: torch.nn.init.normal_(x, mean=0., std=1.), # can be bias
2: lambda x: torch.nn.init.xavier_normal_(x, gain=1.), # can be weight
3: lambda x: torch.nn.init.xavier_uniform_(x, gain=1.), # can be conv1D filter
4: lambda x: torch.nn.init.xavier_uniform_(x, gain=1.), # can be conv2D filter
"default": lambda x: torch.nn.init.constant(x, 1.), # everything else
}
init_all(model, init_funcs)
You can try with torch.nn.init.constant_(x, len(x.shape))
to check that they are appropriately initialized:
init_funcs = {
"default": lambda x: torch.nn.init.constant_(x, len(x.shape))
}
Yes, it is 128, except for temp tables, whose names can only be up to 116 character long. It is perfectly explained here.
And the verification can be easily made with the following script contained in the blog post before:
DECLARE @i NVARCHAR(800)
SELECT @i = REPLICATE('A', 116)
SELECT @i = 'CREATE TABLE #'+@i+'(i int)'
PRINT @i
EXEC(@i)
Deep copy literally performs a deep copy. It means, that if your class has some fields that are references, their values will be copied, not references themselves. If, for example you have two instances of a class, A & B with fields of reference type, and perform a deep copy, changing a value of that field in A won't affect a value in B. And vise-versa. Things are different with shallow copy, because only references are copied, therefore, changing this field in a copied object would affect the original object.
What type of a copy does a copy constructor does?
It is implementation - dependent. This means that there are no strict rules about that, you can implement it like a deep copy or shallow copy, however as far as i know it is a common practice to implement a deep copy in a copy constructor. A default copy constructor performs a shallow copy though.
For this your android application must have uploaded into the android market. when you upload it on the android market then use the following code to open the market with your android application.
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=<packagename>"));
startActivity(intent);
If you want it to download and install from your own server then use the following code
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
startActivity(intent);
I find that num * 1

In my case I had to delete the jars inside .m2/repository
and then did a Maven->Update Maven Project
Looks like the jars were corrupt and deleting and downloading the fresh jar fixed the issue.
1) close the visual studio solution
2) navigate to command prompt --> run as administrator--> iisreset /stop
3) navigate to c--> Windows --> Microsoft.Net --> Framework64--> v4.030319--> Temporary Asp.NET Files --> Delete all the files and folders in this path.
4) Navigate back to command prompt --> iisreset /start
5) Now open the visual studio --> run as administrator --> clean the solution and build it(don't rebuild..just build worked for me)
There is a nice CLI based tool for accessing MSSQL databases now.
It's called mssql-cli
and it's a bit similar to postgres' psql
.
Install for example via pip
(global installation, for a local one omit the sudo
part):
sudo pip install mssql-cli
It is possible of course, use -l:
instead of -l
. For example -l:libXYZ.a
to link with libXYZ.a
. Notice the lib
written out, as opposed to -lXYZ
which would auto expand to libXYZ
.
You got an extra }
to many as seen below:
var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
nav[i].addEventListener('click',function(){
console.log('haha');
} // <-- REMOVE THIS :)
}, false);
};
A very good tool for those things is jsFiddle. I have created a fiddle with your invalid code and when clicking the TidyUp
button it formats your code which makes it clearer if there are any possible mistakes with missing braces.
DEMO - Your code in a fiddle, have a play :)
#!/bin/bash
usage() { echo "Usage: $0 [-s <45|90>] [-p <string>]" 1>&2; exit 1; }
while getopts ":s:p:" o; do
case "${o}" in
s)
s=${OPTARG}
((s == 45 || s == 90)) || usage
;;
p)
p=${OPTARG}
;;
*)
usage
;;
esac
done
shift $((OPTIND-1))
if [ -z "${s}" ] || [ -z "${p}" ]; then
usage
fi
echo "s = ${s}"
echo "p = ${p}"
Example runs:
$ ./myscript.sh
Usage: ./myscript.sh [-s <45|90>] [-p <string>]
$ ./myscript.sh -h
Usage: ./myscript.sh [-s <45|90>] [-p <string>]
$ ./myscript.sh -s "" -p ""
Usage: ./myscript.sh [-s <45|90>] [-p <string>]
$ ./myscript.sh -s 10 -p foo
Usage: ./myscript.sh [-s <45|90>] [-p <string>]
$ ./myscript.sh -s 45 -p foo
s = 45
p = foo
$ ./myscript.sh -s 90 -p bar
s = 90
p = bar
I agree with using frameworks for things like this, just because its easier. I hacked this up real quick, just fades an image out and then switches, also will not work in older versions of IE. But as you can see the code for the actual fade is much longer than the JQuery implementation posted by KARASZI István.
function changeImage() {
var img = document.getElementById("img");
img.src = images[x];
x++;
if(x >= images.length) {
x = 0;
}
fadeImg(img, 100, true);
setTimeout("changeImage()", 30000);
}
function fadeImg(el, val, fade) {
if(fade === true) {
val--;
} else {
val ++;
}
if(val > 0 && val < 100) {
el.style.opacity = val / 100;
setTimeout(function(){ fadeImg(el, val, fade); }, 10);
}
}
var images = [], x = 0;
images[0] = "image1.jpg";
images[1] = "image2.jpg";
images[2] = "image3.jpg";
setTimeout("changeImage()", 30000);
class test
{
public static void useServerPath(string path)
{
if (File.Exists(path)
{
\\...... do whatever you wabt
}
else
{
\\.....
}
}
Now when you call the method from the codebehind
for example :
protected void BtAtualizacao_Click(object sender, EventArgs e)
{
string path = Server.MapPath("Folder") + "\\anifile.txt";
test.useServerPath(path);
}
in this way your code is to simple and with one method u can use multiple path for each call :)
There seems to be quite a variety of ways of preventing the system keyboard from appearing, both programmatically and in xml. However, this is the way that has worked for me while supporting pre API 11 devices.
// prevent system keyboard from appearing
if (android.os.Build.VERSION.SDK_INT >= 11) {
editText.setRawInputType(InputType.TYPE_CLASS_TEXT);
editText.setTextIsSelectable(true);
} else {
editText.setRawInputType(InputType.TYPE_NULL);
editText.setFocusable(true);
}
The reason may be that watcher is declared as local variable to a method and it is garbage collected when the method finishes. You should declare it as a class member. Try the following:
FileSystemWatcher watcher;
private void watch()
{
watcher = new FileSystemWatcher();
watcher.Path = path;
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;
watcher.Filter = "*.*";
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.EnableRaisingEvents = true;
}
private void OnChanged(object source, FileSystemEventArgs e)
{
//Copies file to another directory.
}
I faced this issue when trying to set something to redis. The problem was that I previously used "set" method to set data with a certain key, like
$redis->set('persons', $persons)
Later I decided to change to "hSet" method, and I tried it this way
foreach($persons as $person){
$redis->hSet('persons', $person->id, $person);
}
Then I got the aforementioned error. So, what I had to do is to go to redis-cli and manually delete "persons" entry with
del persons
It simply couldn't write different data structure under existing key, so I had to delete the entry and hSet then.
I ran into this issue by having mismatched build variants. A Dynamic Delivery module was on the debug variant while the remaining modules were on release. Simply changing the Dynamic Delivery module to release, rebuilding, and installing, fixed the issue.
The shortest and easiest answer is: you shouldn't vertically center things in webpages. HTML and CSS simply are not created with that in mind. They are text formatting languages, not user interface design languages.
That said, this is the best way I can think of. However, this will NOT WORK in Internet Explorer 7 and below!
<style>
html, body {
height: 100%;
}
#tableContainer-1 {
height: 100%;
width: 100%;
display: table;
}
#tableContainer-2 {
vertical-align: middle;
display: table-cell;
height: 100%;
}
#myTable {
margin: 0 auto;
}
</style>
<div id="tableContainer-1">
<div id="tableContainer-2">
<table id="myTable" border>
<tr><td>Name</td><td>J W BUSH</td></tr>
<tr><td>Proficiency</td><td>PHP</td></tr>
<tr><td>Company</td><td>BLAH BLAH</td></tr>
</table>
</div>
</div>
In fact, in R, this operation is very easy:
If the matrix 'a' contains some NaN, you just need to use the following code to replace it by 0:
a <- matrix(c(1, NaN, 2, NaN), ncol=2, nrow=2)
a[is.nan(a)] <- 0
a
If the data frame 'b' contains some NaN, you just need to use the following code to replace it by 0:
#for a data.frame:
b <- data.frame(c1=c(1, NaN, 2), c2=c(NaN, 2, 7))
b[is.na(b)] <- 0
b
Note the difference is.nan
when it's a matrix vs. is.na
when it's a data frame.
Doing
#...
b[is.nan(b)] <- 0
#...
yields: Error in is.nan(b) : default method not implemented for type 'list'
because b is a data frame.
Note: Edited for small but confusing typos
From my notes:
Which parses like this:
q=latN+lonW+(label) location of teardrop
t=k keyhole (satelite map)
t=h hybrid
ll=lat,-lon center of map
spn=w.w,h.h span of map, degrees
iwloc has something to do with the info window. hl is obviously language.

My Solution:
I found out that certain anti-virus softwares are actively blocking compilations of DLLs within the directory "Temporary ASP.NET Files", mine was McAfee, the IT people failed to notify me of the installation.
As per advice by both McAfee experts and Microsoft, you need to exclude the directory "Temporary ASP.NET Files" in the real time scanning.
Sources:
Don't disable the Anti-Virus because it is only doing its job. Don't manually copy missing DLL files in the directory \Temporary ASP.NET Files{project name} because thats duct taping.

ES6 React.Component
doesn't auto bind methods to itself. You need to bind them yourself in constructor
. Like this:
constructor (props){
super(props);
this.state = {
loopActive: false,
shuffleActive: false,
};
this.onToggleLoop = this.onToggleLoop.bind(this);
}
This might have changed since the original answer was written, but it looks like you can now use the Models populate function to do this without having to execute an extra findOne. See: http://mongoosejs.com/docs/api.html#model_Model.populate. You'd want to use this inside the save handler just like the findOne is.
The answer from @gunn is correct, target="_blank
makes the link open in a new tab.
But this can be a security risk for you page; you can read about it here. There is a simple solution for that: adding rel="noopener noreferrer"
.
<a style={{display: "table-cell"}} href = "someLink" target = "_blank"
rel = "noopener noreferrer">text</a>
Yes, you can do it by specifying the comparison method. The advantage is the sorted object don't have to be IComparable
aListOfObjects.Sort((x, y) =>
{
int result = x.A.CompareTo(y.A);
return result != 0 ? result : x.B.CompareTo(y.B);
});
I was solving a similar problem on codewars and devised the following solution which worked for me.
This gives the highest count of an integer in an array and also the integer itself. I think it can be applied to string array as well.
To properly sort Strings, remove the function(a, b){return a-b}
from inside the sort()
portion
function mostFrequentItemCount(collection) {
collection.sort(function(a, b){return a-b});
var i=0;
var ans=[];
var int_ans=[];
while(i<collection.length)
{
if(collection[i]===collection[i+1])
{
int_ans.push(collection[i]);
}
else
{
int_ans.push(collection[i]);
ans.push(int_ans);
int_ans=[];
}
i++;
}
var high_count=0;
var high_ans;
i=0;
while(i<ans.length)
{
if(ans[i].length>high_count)
{
high_count=ans[i].length;
high_ans=ans[i][0];
}
i++;
}
return high_ans;
}

Even though 7 years have passed I've just run into this issue as I'm running SpringBoot application that needs to start webpack-dev-server during development and needs to kill it when the backend process stops.
I try to use Runtime.getRuntime().addShutdownHook
but it worked on Windows 10 but not on Windows 7.
I've change it to use a dedicated thread that waits for the process to quit or for InterruptedException
which seems to work correctly on both Windows versions.
private void startWebpackDevServer() {
String cmd = isWindows() ? "cmd /c gradlew webPackStart" : "gradlew webPackStart";
logger.info("webpack dev-server " + cmd);
Thread thread = new Thread(() -> {
ProcessBuilder pb = new ProcessBuilder(cmd.split(" "));
pb.redirectOutput(ProcessBuilder.Redirect.INHERIT);
pb.redirectError(ProcessBuilder.Redirect.INHERIT);
pb.directory(new File("."));
Process process = null;
try {
// Start the node process
process = pb.start();
// Wait for the node process to quit (blocking)
process.waitFor();
// Ensure the node process is killed
process.destroyForcibly();
System.setProperty(WEBPACK_SERVER_PROPERTY, "true");
} catch (InterruptedException | IOException e) {
// Ensure the node process is killed.
// InterruptedException is thrown when the main process exit.
logger.info("killing webpack dev-server", e);
if (process != null) {
process.destroyForcibly();
}
}
});
thread.start();
}
If you need to handle values that cannot be converted separately, you can use this method:

$valueToUse = trim($stringThatMightBeNumeric) + 0;
} catch (\Throwable $th) {
// bail here if you need to

This is a bug in .NET. When PowerShell launches, it caches the output handle (Console.Out). The Encoding property of that text writer does not pick up the value StandardOutputEncoding property.
When you change it from within PowerShell, the Encoding property of the cached output writer returns the cached value, so the output is still encoded with the default encoding.
As a workaround, I would suggest not changing the encoding. It will be returned to you as a Unicode string, at which point you can manage the encoding yourself.
Caching example:
102 [C:\Users\leeholm]
>> $r1 = [Console]::Out
103 [C:\Users\leeholm]
>> $r1
Encoding FormatProvider
-------- --------------
System.Text.SBCSCodePageEncoding en-US
104 [C:\Users\leeholm]
>> [Console]::OutputEncoding = [System.Text.Encoding]::UTF8
105 [C:\Users\leeholm]
>> $r1
Encoding FormatProvider
-------- --------------
System.Text.SBCSCodePageEncoding en-US
select * from Table1 left join Table2 on Table1.id = Table2.id
In the first query Left join compares left-sided table table1 to right-sided table table2.
In Which all the properties of table1 will be shown, whereas in table2 only those properties will be shown in which condition get true.
select * from Table2 right join Table1 on Table1.id = Table2.id
In the first query Right join compares right-sided table table1 to left-sided table table2.
In Which all the properties of table1 will be shown, whereas in table2 only those properties will be shown in which condition get true.
Both queries will give the same result because the order of table declaration in query are different like you are declaring table1 and table2 in left and right respectively in first left join query, and also declaring table1 and table2 in right and left respectively in second right join query.
This is the reason why you are getting the same result in both queries. So if you want different result then execute this two queries respectively,
select * from Table1 left join Table2 on Table1.id = Table2.id
select * from Table1 right join Table2 on Table1.id = Table2.id
You can use order
on the names
, and use that to order the columns when subsetting:
test[ , order(names(test))]
A B C
1 4 1 0
2 2 3 2
3 4 8 4
4 7 3 7
5 8 2 8
For your own defined order, you will need to define your own mapping of the names to the ordering. This would depend on how you would like to do this, but swapping whatever function would to this with order
above should give your desired output.
You may for example have a look at Order a data frame's rows according to a target vector that specifies the desired order, i.e. you can match
your data frame names
against a target vector containing the desired column order.

There is no way to dynamically increase the heap programatically since the heap is allocated when the Java Virtual Machine is started.
However, you can use this command
java -Xmx1024M YourClass
to set the memory to 1024
or, you can set a min max
java -Xms256m -Xmx1024m YourClassNameHere
If you mean VB 6, that would be Private Sub Class_Initialize()

The best approach to use CData sections for the string in strings.xml file to get a actual display of the html content to the TextView the below code snippet will give you the fair idea.
//in string.xml file
<string name="welcome_text"><![CDATA[<b>Welcome,</b> to the forthetyroprogrammers blog Logged in as:]]> %1$s.</string>
//and in Java code
String welcomStr=String.format(getString(R.string.welcome_text),username);
tvWelcomeUser.setText(Html.fromHtml(welcomStr));
CData section in string text keeps the html tag data intact even after formatting text using String.format method. So, Html.fromHtml(str) works fine and you’ll see the bold text in Welcome message.
Output:
Welcome, to your favorite music app store. Logged in as: username
As everyone has mentioned http.server module is equivalent to python -m SimpleHTTPServer
.
But as a warning from https://docs.python.org/3/library/http.server.html#module-http.server
Warning:
http.server
is not recommended for production. It only implements basic security checks.
http.server can also be invoked directly using the -m
switch of the interpreter.
python -m http.server
The above command will run a server by default on port number 8000
. You can also give the port number explicitly while running the server
python -m http.server 9000
The above command will run an HTTP server on port 9000 instead of 8000.
By default, server binds itself to all interfaces. The option -b/--bind specifies a specific address to which it should bind. Both IPv4 and IPv6 addresses are supported. For example, the following command causes the server to bind to localhost only:
python -m http.server 8000 --bind 127.0.0.1
or
python -m http.server 8000 -b 127.0.0.1
Python 3.8 version also supports IPv6 in the bind argument.
By default, server uses the current directory. The option -d/--directory
specifies a directory to which it should serve the files. For example, the following command uses a specific directory:
python -m http.server --directory /tmp/
Directory binding is introduced in python 3.7
I've played around with select items before and without overriding the functionality with JavaScript, I don't think it's possible in Chrome. Whether you use a plugin or write your own code, CSS only is a no go for Chrome/Safari and as you said, Firefox is better at dealing with it.

if you want to open a page on the click of a button in HTML without any scripting language then you can use above code.

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
self.edgesForExtendedLayout = UIRectEdgeNone;
self.extendedLayoutIncludesOpaqueBars = NO;
self.automaticallyAdjustsScrollViewInsets = NO;
}
Full Solution is here
This will clear search when search x is clicked. or will call the search api hit when user hit enter. this code can be further extended with additional esc keyup event matcher. but this should do it all.
document.getElementById("userSearch").addEventListener("search",
function(event){
if(event.type === "search"){
if(event.currentTarget.value !== ""){
hitSearchAjax(event.currentTarget.value);
}else {
clearSearchData();
}
}
});
Cheers.
There is no way.
This question is basically a duplicate of Is there a way to hide the new HTML5 spinbox controls shown in Google Chrome & Opera? but maybe not a full duplicate, since the motivation is given.
If the purpose is “browser's awareness of the content being purely numeric”, then you need to consider what that would really mean. The arrows, or spinners, are part of making numeric input more comfortable in some cases. Another part is checking that the content is a valid number, and on browsers that support HTML5 input enhancements, you might be able to do that using the pattern
attribute. That attribute may also affect a third input feature, namely the type of virtual keyboard that may appear.
For example, if the input should be exactly five digits (like postal numbers might be, in some countries), then <input type="text" pattern="[0-9]{5}">
could be adequate. It is of course implementation-dependent how it will be handled.
$this->load->library('excel');
$file_name = 'Demo';
$arrHeader = array('Name', 'Mobile');
$arrRows = array(0=>array('Name'=>'Jayant','Mobile'=>54545), 1=>array('Name'=>'Jayant1', 'Mobile'=>44454), 2=>array('Name'=>'Jayant2','Mobile'=>111222), 3=>array('Name'=>'Jayant3', 'Mobile'=>99999));
$this->excel->getActiveSheet()->fromArray($arrHeader,'','A1');
$this->excel->getActiveSheet()->fromArray($arrRows);
header('Content-Type: application/vnd.ms-excel'); //mime type
header('Content-Disposition: attachment;filename="'.$file_name.'"'); //tell browser what's the file name
header('Cache-Control: max-age=0'); //no cache
$objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');
$objWriter->save('php://output');
If you want to keep your forEach
syntax, this is a way to keep it efficient (although not as good as a regular for loop). Check immediately for a variable that knows if you want to break out of the loop.
This example uses a anonymous function for creating a function scope around the forEach
which you need to store the done information.
(function(){_x000D_
var element = document.getElementById('printed-result');_x000D_
var done = false;_x000D_
[1,2,3,4].forEach(function(item){_x000D_
if(done){ return; }_x000D_
var text = document.createTextNode(item);_x000D_
element.appendChild(text);_x000D_
if (item === 2){_x000D_
done = true;_x000D_
return;_x000D_
}_x000D_
});_x000D_
})();
_x000D_
<div id="printed-result"></div>
_x000D_
My two cents.
To summarize the other answers, in <jre-path>/lib/security/java.security
you can set the value of the property networkaddress.cache.ttl
to adjust how DNS lookups are cached. Note that this is not a system property but a security property. I was able to set this using:
java.security.Security.setProperty("networkaddress.cache.ttl", "<value>");
This can also be set by the system property -Dsun.net.inetaddr.ttl
though this will not override a security property if it is set elsewhere.
I would also like to add that if you are seeing this issue with web services in WebSphere, as I was, setting networkaddress.cache.ttl
will not be enough. You need to set the system property disableWSAddressCaching
to true
. Unlike the time-to-live property, this can be set as a JVM argument or via System.setProperty
).
IBM has a pretty detailed post on how WebSphere handles DNS caching here. The relevant piece to the above is:
To disable address caching for Web services, you need to set an additional JVM custom property disableWSAddressCaching to true. Use this property to disable address caching for Web services. If your system typically runs with lots of client threads, and you encounter lock contention on the wsAddrCache cache, you can set this custom property to true, to prevent caching of the Web services data.
Maps from JDK are not meant for storing data under duplicated keys.
At best new value will override the previous ones.
Worse scenario is exception (e.g when you try to collect it as a stream):
No duplicates:
Stream.of("one").collect(Collectors.toMap(x -> x, x -> x))
Ok. You will get: $2 ==> {one=one}
Duplicated stream:
Stream.of("one", "not one", "surely not one").collect(Collectors.toMap(x -> 1, x -> x))
Exception java.lang.IllegalStateException: Duplicate key 1 (attempted merging values one and not one) | at Collectors.duplicateKeyException (Collectors.java:133) | at Collectors.lambda$uniqKeysMapAccumulator$1 (Collectors.java:180) | at ReduceOps$3ReducingSink.accept (ReduceOps.java:169) | at Spliterators$ArraySpliterator.forEachRemaining (Spliterators.java:948) | at AbstractPipeline.copyInto (AbstractPipeline.java:484) | at AbstractPipeline.wrapAndCopyInto (AbstractPipeline.java:474) | at ReduceOps$ReduceOp.evaluateSequential (ReduceOps.java:913) | at AbstractPipeline.evaluate (AbstractPipeline.java:234) | at ReferencePipeline.collect (ReferencePipeline.java:578) | at (#4:1)
To deal with duplicated keys - use other package, e.g: https://google.github.io/guava/releases/19.0/api/docs/com/google/common/collect/Multimap.html
There is a lot of other implementations dealing with duplicated keys. Those are needed for web (e.g. duplicated cookie keys, Http headers can have same fields, ...)
Good luck! :)
If the table is already created in the database, then you can add a unique constraint later on by using this SQL query:
ALTER TABLE dbo.User
ADD CONSTRAINT ucCodes UNIQUE (fcode, scode, dcode)
new Date((new Date("07/06/2012 13:30")).toDateString())
_x000D_
I know this might be considered 'wasteful', but in this scenario I often store the key as an additional column in the value record:
d = {'key1' : ('key1', val, val...), 'key2' : ('key2', val, val...) }
it's a tradeoff and feels wrong, but it's simple and works and of course depends on values being tuples rather than simple values.
In case of a range
or any other linearly increasing array you can simply calculate the index programmatically, no need to actually iterate over the array at all:
def first_index_calculate_range_like(val, arr):
if len(arr) == 0:
raise ValueError('no value greater than {}'.format(val))
elif len(arr) == 1:
if arr[0] > val:
return 0
else:
raise ValueError('no value greater than {}'.format(val))
first_value = arr[0]
step = arr[1] - first_value
# For linearly decreasing arrays or constant arrays we only need to check
# the first element, because if that does not satisfy the condition
# no other element will.
if step <= 0:
if first_value > val:
return 0
else:
raise ValueError('no value greater than {}'.format(val))
calculated_position = (val - first_value) / step
if calculated_position < 0:
return 0
elif calculated_position > len(arr) - 1:
raise ValueError('no value greater than {}'.format(val))
return int(calculated_position) + 1
One could probably improve that a bit. I have made sure it works correctly for a few sample arrays and values but that doesn't mean there couldn't be mistakes in there, especially considering that it uses floats...
>>> import numpy as np
>>> first_index_calculate_range_like(5, np.arange(-10, 10))
16
>>> np.arange(-10, 10)[16] # double check
6
>>> first_index_calculate_range_like(4.8, np.arange(-10, 10))
15
Given that it can calculate the position without any iteration it will be constant time (O(1)
) and can probably beat all other mentioned approaches. However it requires a constant step in the array, otherwise it will produce wrong results.
A more general approach would be using a numba function:
@nb.njit
def first_index_numba(val, arr):
for idx in range(len(arr)):
if arr[idx] > val:
return idx
return -1
That will work for any array but it has to iterate over the array, so in the average case it will be O(n)
:
>>> first_index_numba(4.8, np.arange(-10, 10))
15
>>> first_index_numba(5, np.arange(-10, 10))
16
Even though Nico Schlömer already provided some benchmarks I thought it might be useful to include my new solutions and to test for different "values".
The test setup:
import numpy as np
import math
import numba as nb
def first_index_using_argmax(val, arr):
return np.argmax(arr > val)
def first_index_using_where(val, arr):
return np.where(arr > val)[0][0]
def first_index_using_nonzero(val, arr):
return np.nonzero(arr > val)[0][0]
def first_index_using_searchsorted(val, arr):
return np.searchsorted(arr, val) + 1
def first_index_using_min(val, arr):
return np.min(np.where(arr > val))
def first_index_calculate_range_like(val, arr):
if len(arr) == 0:
raise ValueError('empty array')
elif len(arr) == 1:
if arr[0] > val:
return 0
else:
raise ValueError('no value greater than {}'.format(val))
first_value = arr[0]
step = arr[1] - first_value
if step <= 0:
if first_value > val:
return 0
else:
raise ValueError('no value greater than {}'.format(val))
calculated_position = (val - first_value) / step
if calculated_position < 0:
return 0
elif calculated_position > len(arr) - 1:
raise ValueError('no value greater than {}'.format(val))
return int(calculated_position) + 1
@nb.njit
def first_index_numba(val, arr):
for idx in range(len(arr)):
if arr[idx] > val:
return idx
return -1
funcs = [
first_index_using_argmax,
first_index_using_min,
first_index_using_nonzero,
first_index_calculate_range_like,
first_index_numba,
first_index_using_searchsorted,
first_index_using_where
]
from simple_benchmark import benchmark, MultiArgument
and the plots were generated using:
%matplotlib notebook
b.plot()
b = benchmark(
funcs,
{2**i: MultiArgument([0, np.arange(2**i)]) for i in range(2, 20)},
argument_name="array size")
The numba function performs best followed by the calculate-function and the searchsorted function. The other solutions perform much worse.
b = benchmark(
funcs,
{2**i: MultiArgument([2**i-2, np.arange(2**i)]) for i in range(2, 20)},
argument_name="array size")
For small arrays the numba function performs amazingly fast, however for bigger arrays it's outperformed by the calculate-function and the searchsorted function.
b = benchmark(
funcs,
{2**i: MultiArgument([np.sqrt(2**i), np.arange(2**i)]) for i in range(2, 20)},
argument_name="array size")
This is more interesting. Again numba and the calculate function perform great, however this is actually triggering the worst case of searchsorted which really doesn't work well in this case.
Another interesting point is how these function behave if there is no value whose index should be returned:
arr = np.ones(100)
value = 2
for func in funcs:
print(func.__name__)
try:
print('-->', func(value, arr))
except Exception as e:
print('-->', e)
With this result:
first_index_using_argmax
--> 0
first_index_using_min
--> zero-size array to reduction operation minimum which has no identity
first_index_using_nonzero
--> index 0 is out of bounds for axis 0 with size 0
first_index_calculate_range_like
--> no value greater than 2
first_index_numba
--> -1
first_index_using_searchsorted
--> 101
first_index_using_where
--> index 0 is out of bounds for axis 0 with size 0
Searchsorted, argmax, and numba simply return a wrong value. However searchsorted
and numba
return an index that is not a valid index for the array.
The functions where
, min
, nonzero
and calculate
throw an exception. However only the exception for calculate
actually says anything helpful.
That means one actually has to wrap these calls in an appropriate wrapper function that catches exceptions or invalid return values and handle appropriately, at least if you aren't sure if the value could be in the array.
Note: The calculate and searchsorted
options only work in special conditions. The "calculate" function requires a constant step and the searchsorted requires the array to be sorted. So these could be useful in the right circumstances but aren't general solutions for this problem. In case you're dealing with sorted Python lists you might want to take a look at the bisect module instead of using Numpys searchsorted.
Thanks all, I had the same issue. I have a task that runs via a generic user account not linked to a particular person. This user as somehow logged off the VM, when I was trying to fix it I was logged in as me and not that user.
Logging back in with that user fixed the issue!
You must use some of the C # conversion systems:
string to boolean: True to true
string str = "True";
bool mybool = System.Convert.ToBoolean(str);
boolean to string: true to True
bool mybool = true;
string str = System.Convert.ToString(mybool);
//or
string str = mybool.ToString();
bool.Parse
expects one parameter which in this case is str, even .
Convert.ToBoolean
expects one parameter.
bool.TryParse
expects two parameters, one entry (str) and one out (result).
If TryParse
is true, then the conversion was correct, otherwise an error occurred
string str = "True";
bool MyBool = bool.Parse(str);
//Or
string str = "True";
if(bool.TryParse(str, out bool result))
{
//Correct conversion
}
else
{
//Incorrect, an error has occurred
}
$("#idform").validate({
rules: {
'roles': {
required: true,
},
},
messages: {
'roles': {
required: "One Option please",
},
}
});
My guess: Because Twitter sees the need to support legacy browsers, otherwise they would be using the :before
/ :after
pseudo-elements.
Legacy browsers don't support those pseudo-elements I mentioned, so they need to use an actual HTML element for the icons, and since icons don't have an 'exclusive' tag, they just went with the <i>
tag, and all browsers support that tag.
They could've certainly used a <span>
, just like you are (which is TOTALLY fine), but probably for the reason I mentioned above plus the ones mentioned by Quentin, is also why Bootstrap is using the <i>
tag.
It's a bad practice when you use extra markup for styling reasons, that's why pseudo-elements were invented, to separate content from style... but when you see the need to support legacy browsers, sometimes you're forced to do these kind of things.
PS. The fact that icons start with an 'i' and that there's an <i>
tag, is completely coincidental.
in kotlin :
val sharingIntent = Intent(android.content.Intent.ACTION_SEND)
sharingIntent.type = "text/plain"
val shareBody = "Application Link : https://play.google.com/store/apps/details?id=${App.context.getPackageName()}"
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "App link")
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody)
startActivity(Intent.createChooser(sharingIntent, "Share App Link Via :"))
For the few people asking for a generic method, this should help you (5 years later :p).
For my below example, I'm pulling the RequestMapping URL value from methods that have the RequestMapping annotation. To adapt this for fields, just change the
for (Method method: clazz.getMethods())
to
for (Field field: clazz.getFields())
And swap usage of RequestMapping for whatever annotation you are looking to read. But make sure that the annotation has @Retention(RetentionPolicy.RUNTIME).
public static String getRequestMappingUrl(final Class<?> clazz, final String methodName)
{
// Only continue if the method name is not empty.
if ((methodName != null) && (methodName.trim().length() > 0))
{
RequestMapping tmpRequestMapping;
String[] tmpValues;
// Loop over all methods in the class.
for (Method method: clazz.getMethods())
{
// If the current method name matches the expected method name, then keep going.
if (methodName.equalsIgnoreCase(method.getName()))
{
// Try to extract the RequestMapping annotation from the current method.
tmpRequestMapping = method.getAnnotation(RequestMapping.class);
// Only continue if the current method has the RequestMapping annotation.
if (tmpRequestMapping != null)
{
// Extract the values from the RequestMapping annotation.
tmpValues = tmpRequestMapping.value();
// Only continue if there are values.
if ((tmpValues != null) && (tmpValues.length > 0))
{
// Return the 1st value.
return tmpValues[0];
}
}
}
}
}
// Since no value was returned, log it and return an empty string.
logger.error("Failed to find RequestMapping annotation value for method: " + methodName);
return "";
}
i had the same problem and I solved it.
var vm = new MessagesViewModel()
ko.applyBindings(vm)
function ShowMessagesList() {
vm.getData("MyParams")
}
setInterval(ShowMessagesList, 10000)
I could tolerate my field concatenated into multiple rows each less than the 4000 character limit - did the following:
with PRECALC as (select
floor(4000/(max(length(MY_COLUMN)+LENGTH(',')))) as MAX_FIELD_LENGTH
from MY_TABLE)
select LISTAGG(MY_COLUMN,',') WITHIN GROUP(ORDER BY floor(rownum/MAX_FIELD_LENGTH), MY_COLUMN)
from MY_TABLE, PRECALC
group by floor(rownum/MAX_FIELD_LENGTH)
;
You can use the Select
parameter and use COUNT
in the request. It "returns the number of matching items, rather than the matching items themselves". Important, as brought up by Saumitra R. Bhave in a comment, "If the size of the Query result set is larger than 1 MB, then ScannedCount and Count will represent only a partial count of the total items. You will need to perform multiple Query operations in order to retrieve all of the results".
I'm Not familiar with PHP but here is how you could use it with Java. And then instead of using Count
(which I am guessing is a function in PHP) on the 'Items'
you can use the Count
value from the response - $result['Count']
:
final String week = "whatever";
final Integer myPoint = 1337;
Condition weekCondition = new Condition()
.withComparisonOperator(ComparisonOperator.EQ)
.withAttributeValueList(new AttributeValue().withS(week));
Condition myPointCondition = new Condition()
.withComparisonOperator(ComparisonOperator.GE)
.withAttributeValueList(new AttributeValue().withN(myPoint.toString()))
Map<String, Condition> keyConditions = new HashMap<>();
keyConditions.put("week", weekCondition);
keyConditions.put("point", myPointCondition);
QueryRequest request = new QueryRequest("game_table");
request.setIndexName("week-point-index");
request.setSelect(Select.COUNT);
request.setKeyConditions(keyConditions);
QueryResult result = dynamoDBClient.query(request);
Integer count = result.getCount();
If you don't need to emulate the WHERE
clause, you can use a DescribeTable
request and use the resulting item count to get an estimate.
The number of items in the specified table. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.
Also, an important note from the documentation as noted by Saumitra R. Bhave in the comments on this answer:
If the size of the
Query
result set is larger than 1 MB,ScannedCount
andCount
represent only a partial count of the total items. You need to perform multipleQuery
operations to retrieve all the results (see Paginating Table Query Results).
It is impossible to terminate a thread unless the code running in that thread checks for and allows termination.
You said: "Sadly I must kill/restart it ... I don't have complete control over the contents of the thread and for my situation it requires a restart"
If the contents of the thread does not allow for termination of its exectuion then you can not terminate that thread.
In your post you said: "My first attempt was with ExecutorService but I can't seem to find a way for it restart a task. When I use .shutdownnow()..."
If you look at the source of "shutdownnow" it just runs through and interrupts the currently running threads. This will not stop their execution unless the code in those threads checks to see if it has been ineterrupted and, if so, stops execution itself. So shutdownnow is probably not doing what you think.
Let me illustrate what I mean when I say that the contents of the thread must allow for that thread to be terminated:
myExecutor.execute(new Runnable() {
public void run() {
while (true) {
System.out.println("running");
}
}
});
myExecutor.shutdownnow();
That thread will continue to run forever, even though shutdownnow was called, because it never checks to see if it has been terminated or not. This thread, however, will shut down:
myExecutor.execute(new Runnable() {
public void run() {
while (!Thread.interrupted()) {
System.out.println("running");
}
}
});
myExecutor.shutdownnow();
Since this thread checks to see whether or not it has been interrupted / shut down / terminated.
So if you want a thread that you can shut down, you need to make sure it checks to see if it has been interrupted. If you want a thread that you can "shut down" and "restart" you can make a runnable that can take new tasks as was mentioned before.
Why can you not shut down a running thread? Well I actually lied, you can call "yourThread.stop()" but why is this a bad idea? The thread could be in a synchronized (or other critical section, but we will limit ourselves to setions guarded by the syncrhonized key word here) section of code when you stop it. synch blocks are supposed to be executed in their entirity and only by one thread before being accessed by some other thread. If you stop a thread in the middle of a synch block, the protection put into place by the synch block is invalidated and your program will get into an unknown state. Developers make put stuff in synch blocks to keep things in synch, if you use threadInstance.stop() you destroy the meaning of synchronize, what the developer of that code was trying to accomplish and how the developer of that code expected his synchronized blocks to behave.

"myapp/common"
"myapp/routers"
)
I use viewbag with the same variable name in the Controller. E.g if the variable is called "IsActive" and I want this to default to true on the "Create" form, on the Create Action I set the value ViewBag.IsActive = true;
public ActionResult Create()

ViewBag.IsActive = true;
return View();

The following are examples of useful code snippets that can be used – some of the examples use standard JavaScript functions and are not specific to jQuery:
>>> ', '.join(i for i in dir(a) if not i.startswith('__'))
'multi, str'
This of course will print any methods or attributes in the class definition. You can exclude "private" methods by changing i.startwith('__')
to i.startwith('_')
To those who are stuck wondering why a window flashes and goes away without doing anything, the problem may related to the RELATIVE path in your Python script. e.g. you used ".\". Even the Python script and Excel Workbook is in the same directory, the Current Directory may still be different. If you don't want to modify your code to change it to an absolute path. Just change your current Excel directory before you run the python script by:
ChDir ActiveWorkbook.Path
I'm just giving a example here. If the flash do appear, one of the first issues to check is the Current Working Directory.
In my first encounter with this error my user had rights to "write" to the file but not the containing directory. Check the permissions of the directory containing the file.

This Error occurred for me because of duplicate records(16K)
I tried with unique it worked .
but again when I tried merge without unique same proble occurred Second time it was due to commit
after merge if commit is not done same Error will be shown.
Without unique, Query will work if commit is given after each merge operation.
I got the same error but in PyCharm because I accidentally deleted my VCS origin. After re-adding my origin I ran:

If you use LinearLayout
you can add gravity center:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
<Button
android:layout_width="200dp"
android:layout_height="wrap_content"
/>
</LinearLayout>`
If there are duplicate keys in the first list that map to different values in the second list, like a 1-to-many relationship, but you need the values to be combined or added or something instead of updating, you can do this:
i = iter(["a", "a", "b", "c", "b"])
j = iter([1,2,3,4,5])
k = list(zip(i, j))
for (x,y) in k:
if x in d:
d[x] = d[x] + y #or whatever your function needs to be to combine them
else:
d[x] = y
In that example, d == {'a': 3, 'c': 4, 'b': 8}
Try this setup:
a = [["a","b","c",],["d","e"],["f","g","h"]]
To print the 2nd element in the 1st list ("b"), use print a[0][1]
- For the 2nd element in 3rd list ("g"): print a[2][1]
The first brackets reference which nested list you're accessing, the second pair references the item in that list.

You need the Microsoft.AspNet.WebApi.Core package.
You can see it in the .csproj file:

In .NET Framework 4 and later, the Stream
class has a built-in CopyTo
method that you can use.
For earlier versions of the framework, the handy helper function to have is:
public static void CopyStream(Stream input, Stream output)
{
byte[] b = new byte[32768];
int r;
while ((r = input.Read(b, 0, b.Length)) > 0)
output.Write(b, 0, r);
}
Then use one of the above methods to copy to a MemoryStream
and call GetBuffer
on it:
var file = new FileStream("c:\\foo.txt", FileMode.Open);
var mem = new MemoryStream();
// If using .NET 4 or later:
file.CopyTo(mem);
// Otherwise:
CopyStream(file, mem);
// getting the internal buffer (no additional copying)
byte[] buffer = mem.GetBuffer();
long length = mem.Length; // the actual length of the data
// (the array may be longer)
// if you need the array to be exactly as long as the data
byte[] truncated = mem.ToArray(); // makes another copy
Edit: originally I suggested using Jason's answer for a Stream
that supports the Length
property. But it had a flaw because it assumed that the Stream
would return all its contents in a single Read
, which is not necessarily true (not for a Socket
, for example.) I don't know if there is an example of a Stream
implementation in the BCL that does support Length
but might return the data in shorter chunks than you request, but as anyone can inherit Stream
this could easily be the case.
It's probably simpler for most cases to use the above general solution, but supposing you did want to read directly into an array that is bigEnough
:
byte[] b = new byte[bigEnough];
int r, offset;
while ((r = input.Read(b, offset, b.Length - offset)) > 0)
offset += r;
That is, repeatedly call Read
and move the position you will be storing the data at.

Update, as commented by VonC in How to remove old Docker containers.
With Docker 1.13 (Q4 2016), you now have:
docker system prune
will delete ALL unused data (i.e., in order: containers stopped, volumes without containers and images with no containers).
See PR 26108 and commit 86de7c0, which are introducing a few new commands to help facilitate visualizing how much space the Docker daemon data is taking on disk and allowing for easily cleaning up "unneeded" excess.
docker system prune
WARNING! This will remove:
- all stopped containers
- all volumes not used by at least one container
- all images without at least one container associated to them

Besides just using include()
or include_once()
to include the header and footer, one thing I have found useful is being able to have a custom page title or custom head tags to be included for each page, yet still have the header in a partial include. I usually accomplish this as follows:
In the site pages:
<?php
$PageTitle="New Page Title";
function customPageHeader(){?>
<!--Arbitrary HTML Tags-->
<?php }
include_once('header.php');
//body contents go here
include_once('footer.php');
?>
And, in the header.php file:
<!doctype html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title><?= isset($PageTitle) ? $PageTitle : "Default Title"?></title>
<!-- Additional tags here -->
<?php if (function_exists('customPageHeader')){
customPageHeader();
}?>
</head>
<body>
Maybe a bit beyond the scope of your original question, but it is useful to allow a bit more flexibility with the include.
This may not be the most popular or efficient method, but I tend to forgo strong datatypes in SQLite since they are all essentially dumped in as strings anyway.
I've written a thin C# wrapper around the SQLite library before (when using SQLite with C#, of course) to handle insertions and extractions to and from SQLite as if I were dealing with DateTime objects.
Your second question
How many columns can be used together as a primary key in a given table?
is implementation specific: it's defined in the actual DBMS being used.[1],[2],[3] You have to inspect the technical specification of the database system you use. Some are very detailed, some are not. Searching the web about such limitations can be hard because the terminology varies. The term composite primary key should be mandatory ;)
If you cannot find explicit information, try creating a test database to ensure you can expect stable (and specific) handling of the limit violations (which are to be expected). Be careful to get the right information about this: sometimes the limits are accumulated, and you'll see different results with different database layouts.
As asnwered here by @mcortesi if you remove the sourceMaps from the css loader query the css will be built without use of blob and the data urls will be parsed fine
This should work
function updatePostID(val)
{
document.getElementById('PostID').value = val;
//and probably call document.forms[0].submit();
}
Then have a hidden field or other control for the PostID
@Html.Hidden("PostID", Model.addcomment.PostID)
//OR
@Html.HiddenFor(model => model.addcomment.PostID)
You could do something like this
var option=document.getElementsByName('Gender');
if (!(option[0].checked || option[1].checked)) {
alert("Please Select Your Gender");
return false;
}
I realise this answer is not a direct response to the problem described by the OP, but I found this question as a result of searching for the same error message. I thought it worth posting my experience here just in case anybody is muddling over the same thing...
You can encounter the error in question as a result of a poorly formatted for
loop over an associative array. In a fit of bone-headedness, I was using -> instead of => in my for
statement:
foreach ($object->someArray as $key->$val) {
// do something
}
Of course, I should have had:
foreach ($object->someArray as $key=>$val) {
// do something
}
I confused myself at first, thinking the reported error was referring to the someArray property!
To change the size of (almost) all text elements, in one place, and synchronously, rel()
is quite efficient:
g+theme(text = element_text(size=rel(3.5))
You might want to tweak the number a bit, to get the optimum result. It sets both the horizontal and vertical axis labels and titles, and other text elements, on the same scale. One exception is faceted grids' titles which must be manually set to the same value, for example if both x and y facets are used in a graph:
theme(text = element_text(size=rel(3.5)),
strip.text.x = element_text(size=rel(3.5)),
strip.text.y = element_text(size=rel(3.5)))
To get estimates, see Greg Smith's answer.
To get exact counts, the other answers so far are plagued with some issues, some of them serious (see below). Here's a version that's hopefully better:
CREATE FUNCTION rowcount_all(schema_name text default 'public')
RETURNS table(table_name text, cnt bigint) as
$$
declare
table_name text;
begin
for table_name in SELECT c.relname FROM pg_class c
JOIN pg_namespace s ON (c.relnamespace=s.oid)
WHERE c.relkind = 'r' AND s.nspname=schema_name
LOOP
RETURN QUERY EXECUTE format('select cast(%L as text),count(*) from %I.%I',
table_name, schema_name, table_name);
END LOOP;
end
$$ language plpgsql;
It takes a schema name as parameter, or public
if no parameter is given.
To work with a specific list of schemas or a list coming from a query without modifying the function, it can be called from within a query like this:
WITH rc(schema_name,tbl) AS (
select s.n,rowcount_all(s.n) from (values ('schema1'),('schema2')) as s(n)
)
SELECT schema_name,(tbl).* FROM rc;
This produces a 3-columns output with the schema, the table and the rows count.
Now here are some issues in the other answers that this function avoids:
Table and schema names shouldn't be injected into executable SQL without being quoted, either with quote_ident
or with the more modern format()
function with its %I
format string. Otherwise some malicious person may name their table tablename;DROP TABLE other_table
which is perfectly valid as a table name.
Even without the SQL injection and funny characters problems, table name may exist in variants differing by case. If a table is named ABCD
and another one abcd
, the SELECT count(*) FROM...
must use a quoted name otherwise it will skip ABCD
and count abcd
twice. The %I
of format does this automatically.
information_schema.tables
lists custom composite types in addition to tables, even when table_type is 'BASE TABLE'
(!). As a consequence, we can't iterate oninformation_schema.tables
, otherwise we risk having select count(*) from name_of_composite_type
and that would fail. OTOH pg_class where relkind='r'
should always work fine.
The type of COUNT() is bigint
, not int
. Tables with more than 2.15 billion rows may exist (running a count(*) on them is a bad idea, though).
A permanent type need not to be created for a function to return a resultset with several columns. RETURNS TABLE(definition...)
is a better alternative.
iPad Detection
You should be able to detect an iPad user by taking a look at the userAgent
property:
var is_iPad = navigator.userAgent.match(/iPad/i) != null;
iPhone/iPod Detection
Similarly, the platform
property to check for devices like iPhones or iPods:
function is_iPhone_or_iPod(){
return navigator.platform.match(/i(Phone|Pod))/i)
}
Notes
While it works, you should generally avoid performing browser-specific detection as it can often be unreliable (and can be spoofed). It's preferred to use actual feature-detection in most cases, which can be done through a library like Modernizr.
As pointed out in Brennen's answer, issues can arise when performing this detection within the Facebook app. Please see his answer for handling this scenario.

Try str_detect()
from the stringr package, which detects the presence or absence of a pattern in a string.
Here is an approach that also incorporates the %>%
pipe and filter()
from the dplyr package:
library(stringr)
library(dplyr)
CO2 %>%
filter(str_detect(Treatment, "non"))
Plant Type Treatment conc uptake
1 Qn1 Quebec nonchilled 95 16.0
2 Qn1 Quebec nonchilled 175 30.4
3 Qn1 Quebec nonchilled 250 34.8
4 Qn1 Quebec nonchilled 350 37.2
5 Qn1 Quebec nonchilled 500 35.3
...
This filters the sample CO2 data set (that comes with R) for rows where the Treatment variable contains the substring "non". You can adjust whether str_detect
finds fixed matches or uses a regex - see the documentation for the stringr package.

otherwise you can load your JSON file relative to import.meta.url

const config = JSON.parse(await readFile(new URL('../config.json', import.meta.url)));
you can also use module.createRequire()

const require = createRequire(import.meta.url);
const config = require('../config.json');
On Ubuntu, when mysqli is missing, execute the following,

Note: This could be 7.0 and up, but for example Drupal recommends PHP 7.2 on grounds of security among others.
To check your PHP version, on the command-line type:
php -v
You do exactly the same if you are missing mbstring:

The advantage of it - no need to specify keys, and it would still work if some keys are missing in some of dictionaries.

:param item: dict
:return: sorted list of tuples (k, v)

I am working on a MVC5/Web API project and needed to be able to get authorization for the Web Api methods. When my index view is first loaded I make a call to the 'token' Web API method which I believe is created automatically.
The client side code (CoffeeScript) to get the token is:
getAuthenticationToken = (username, password) ->
dataToSend = "username=" + username + "&password=" + password
dataToSend += "&grant_type=password"
$.post("/token", dataToSend).success saveAccessToken
If successful the following is called, which saves the authentication token locally:
saveAccessToken = (response) ->
window.authenticationToken = response.access_token
Then if I need to make an Ajax call to a Web API method that has the [Authorize] tag I simply add the following header to my Ajax call:
{ "Authorization": "Bearer " + window.authenticationToken }

Here's a simple demo where you can watch each one executing (and experiment if you'd like).
From Angular's module docs:
Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.
Run blocks are the closest thing in Angular to the main method. A run block is the code which needs to run to kickstart the application. It is executed after all of the services have been configured and the injector has been created. Run blocks typically contain code which is hard to unit-test, and for this reason should be declared in isolated modules, so that they can be ignored in the unit-tests.
One situation where run blocks are used is during authentications.

In your case, use this:
Server=localhost;Database=employeedetails;Integrated Security=SSPI
Update: obviously, the service account used to run ASP.NET web apps doesn't have access to SQL Server, and judging from that error message, you're probably using "anonymous authentication" on your web site.
So you either need to add this account IIS APPPOOL\ASP.NET V4.0
as a SQL Server login and give that login access to your database, or you need to switch to using "Windows authentication" on your ASP.NET web site so that the calling Windows account will be passed through to SQL Server and used as a login on SQL Server.
In addition, it's convenient to define variables referring to objects. For instance,
Sub CreateTable()
Dim lo as ListObject
Set lo = ActiveSheet.ListObjects.Add(xlSrcRange, Range("$B$1:$D$16"), , xlYes)
lo.Name = "Table1"
lo.TableStyle = "TableStyleLight2"
...
End Sub

You need to have the System.Linq
namespace included in your view since Select is an extension method. You have a couple of options on how to do this:
Add @using System.Linq
to the top of your cshtml file.
If you find that you will be using this namespace often in many of your views, you can do this for all views by modifying the web.config inside of your Views folder (not the one at the root). You should see a pages/namespace XML element, create a new add
child that adds System.Linq. Here is an example:
<configuration>
<system.web.webPages.razor>
<pages>
<namespaces>
<add namespace="System.Linq" />
</namespaces>
</pages>
</system.web.webPages.razor>
</configuration>

If I understand you correctly, you want to compose a multipart request manually from an HTTP/REST console. The multipart format is simple; a brief introduction can be found in the HTML 4.01 spec. You need to come up with a boundary, which is a string not found in the content, let’s say HereGoes
. You set request header Content-Type: multipart/form-data; boundary=HereGoes
. Then this should be a valid request body:
--HereGoes
Content-Disposition: form-data; name="myJsonString"
Content-Type: application/json
{"foo": "bar"}
--HereGoes

Hibernate's PostgreSQL dialect isn't very bright. It doesn't know about your per-SERIAL sequences, and is assuming there's a global database-wide sequence called "hibernate_sequence" that it can use.
(UPDATE: It appears that newer Hibernate versions may use the default per-table sequences when GenerationType.IDENTITY
is specified. Test your version and use this instead of the below if it works for you.)
You need to change your mappings to explicitly specify each sequence. It's annoying, repetitive, and pointless.
@Entity
@Table(name = "JUDGEMENTS")
public class Judgement implements Serializable, Cloneable {
private static final long serialVersionUID = -7049957706738879274L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator="judgements_id_seq")
@SequenceGenerator(name="judgements_id_seq", sequenceName="judgements_id_seq", allocationSize=1)
@Column(name = "JUD_ID")
private Long _judId;
...
The allocationSize=1
is quite important. If you omit it, Hibernate will blindly assume that the sequence is defined with INCREMENT 50
so when it gets a value from a sequence it can use that value and the 49 values below it as unique generated keys. If your database sequences increment by 1 - the default - then this will result in unique violations as Hibernate tries to re-use existing keys.
Note that getting one key at a time will result in an additional round trip per insert. As far as I can tell Hibernate isn't capable of using INSERT ... RETURNING
to efficiently return generated keys, nor can it apparently use the JDBC generated keys interface. If you tell it to use a sequence, it'll call nextval
to get the value then insert
that explicitly, resulting in two round trips. To reduce the cost of that, you can set a greater increment on key sequences with lots of inserts , remembering to set it on the mapping and the underlying database sequence. That'll cause Hibernate to call nextval
less frequently and cache blocks of keys to hand out as it goes.
I'm sure you can see from the above that I don't agree with the Hibernate design choices made here, at least from the perspective of using it with PostgreSQL. They should be using getGeneratedKeys
or using INSERT ... RETURNING
with DEFAULT
for the key, letting the database take care of this without Hibernate having to trouble its self over the names of the sequences or explicit access to them.
BTW, if you're using Hibernate with Pg you'll possibly also want an oplock trigger for Pg to allow Hibernate's optimistic locking to interact safely with normal database locking. Without it or something like it your Hibernate updates will tend to clobber changes made via other regular SQL clients. Ask me how I know.
The following code did the trick for me.
html:
<div class="back" onclick="goBackOrGoHome()">
Back
</div>
js:
home_url = [YOUR BASE URL];
pathArray = document.referrer.split( '/' );
protocol = pathArray[0];
host = pathArray[2];
url_before = protocol + '//' + host;
url_now = window.location.protocol + "//" + window.location.host;
function goBackOrGoHome(){
if ( url_before == url_now) {
window.history.back();
}else{
window.location = home_url;
};
}
So, you use document.referrer
to set the domain of the page you come from. Then you compare that with your current url using window.location
.
If they are from the same domain, it means you are coming from your own site and you send them window.history.back()
. If they are not the same, you are coming from somewhere else and you should redirect home or do whatever you like.
If you are using ES2015 you have access to the Object.assign. You can use it as follows to update a nested object.
this.setState({
someProperty: Object.assign({}, this.state.someProperty, {flag: false})
});
You merge the updated properties with the existing and use the returned object to update the state.
Edit: Added an empty object as target to the assign function to make sure the state isn't mutated directly as carkod pointed out.
Using this source code you can upload multiple file like google one by one through ajax. Also you can see the uploading progress
HTML
<input type="file" id="multiupload" name="uploadFiledd[]" multiple >
<button type="button" id="upcvr" class="btn btn-primary">Start Upload</button>
<div id="uploadsts"></div>
Javascript
<script>
function uploadajax(ttl,cl){
var fileList = $('#multiupload').prop("files");
$('#prog'+cl).removeClass('loading-prep').addClass('upload-image');
var form_data = "";
form_data = new FormData();
form_data.append("upload_image", fileList[cl]);
var request = $.ajax({
url: "upload.php",
cache: false,
contentType: false,
processData: false,
async: true,
data: form_data,
type: 'POST',
xhr: function() {
var xhr = $.ajaxSettings.xhr();
if(xhr.upload){
xhr.upload.addEventListener('progress', function(event){
var percent = 0;
if (event.lengthComputable) {
percent = Math.ceil(event.loaded / event.total * 100);
}
$('#prog'+cl).text(percent+'%')
}, false);
}
return xhr;
},
success: function (res, status) {
if (status == 'success') {
percent = 0;
$('#prog' + cl).text('');
$('#prog' + cl).text('--Success: ');
if (cl < ttl) {
uploadajax(ttl, cl + 1);
} else {
alert('Done');
}
}
},
fail: function (res) {
alert('Failed');
}
})
}
$('#upcvr').click(function(){
var fileList = $('#multiupload').prop("files");
$('#uploadsts').html('');
var i;
for ( i = 0; i < fileList.length; i++) {
$('#uploadsts').append('<p class="upload-page">'+fileList[i].name+'<span class="loading-prep" id="prog'+i+'"></span></p>');
if(i == fileList.length-1){
uploadajax(fileList.length-1,0);
}
}
});
</script>
PHP
upload.php
move_uploaded_file($_FILES["upload_image"]["tmp_name"],$_FILES["upload_image"]["name"]);
The solution proposed from superM worked for me for a long time, but lately I tested it on 4.2 (HTC One) and it stopped working there. I am aware that this is a workaround, but it was the only one which worked for me with all devices and versions.
According to the documentation, developers are asked to "use the system MediaStore" to send binary content. This, however, has the (dis-)advantage, that the media content will be saved permanently on the device.
If this is an option for you, you might want to grant permission WRITE_EXTERNAL_STORAGE
and use the system-wide MediaStore.
Bitmap icon = mBitmap;
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, "title");
values.put(Images.Media.MIME_TYPE, "image/jpeg");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI,
values);
OutputStream outstream;
try {
outstream = getContentResolver().openOutputStream(uri);
icon.compress(Bitmap.CompressFormat.JPEG, 100, outstream);
outstream.close();
} catch (Exception e) {
System.err.println(e.toString());
}
share.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(share, "Share Image"));
There is a great article about this exact issue on the Android developer website: Loading Large Bitmaps Efficiently
The docs explicitly says that java.sql.Date
will throw:
IllegalArgumentException
- if the date given is not in the JDBC date escape format (yyyy-[m]m-[d]d
)
Also you shouldn't need to convert a date to a String
then to a sql.date
, this seems superfluous (and bug-prone!). Instead you could:
java.sql.Date sqlDate := new java.sql.Date(now.getTime());
prs.setDate(2, sqlDate);
prs.setDate(3, sqlDate);
i followed all the suggested steps, in particular the ones provided from ios_dev but my iPhone was not recognized from Xcode and i was not able to debug over WiFi. Right click on the left panel over my iDevice in "Devices and Simulators" window, then "Connect via IP Address...", inserted the iPhone IP and now it correctly works
My problem was in web.config: UnobtrusiveJavaScriptEnabled was turned off
<appSettings>
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="false" />
</appSettings>
I changed to and now works:
`<add key="UnobtrusiveJavaScriptEnabled" value="true" />`
In SQL Server 2016 it has its own link:

Every time someone mentions SOAP/WSDL, I think of objects and classes defined in xml...
"You use SOAP just the same way that you would any PHP class. However, in this case the class does not exist in the local applications file system, but at a remote site accessed over http." ... "If we think of using a SOAP service as just another PHP class then the WSDL document is a list of all the available class methods and properties. "
..and whenever someone talks about REST I think of HTTP's commands (request methods) like POST, GET and DELETE
instanceof
can be used to determine the actual type of an object:
class A { }
class C extends A { }
class D extends A { }
public static void testInstance(){
A c = new C();
A d = new D();
Assert.assertTrue(c instanceof A && d instanceof A);
Assert.assertTrue(c instanceof C && d instanceof D);
Assert.assertFalse(c instanceof D);
Assert.assertFalse(d instanceof C);
}
To increase performance when downloading a large file, the below may work a bit more efficiently:
import requests
from contextlib import closing
import csv
url = "http://download-and-process-csv-efficiently/python.csv"
with closing(requests.get(url, stream=True)) as r:
reader = csv.reader(r.iter_lines(), delimiter=',', quotechar='"')
for row in reader:
# Handle each row here...
print row
By setting stream=True
in the GET request, when we pass r.iter_lines()
to csv.reader(), we are passing a generator to csv.reader(). By doing so, we enable csv.reader() to lazily iterate over each line in the response with for row in reader
.
This avoids loading the entire file into memory before we start processing it, drastically reducing memory overhead for large files.
Under the connection properties, uncheck "Enable background refresh". This will make the connection refresh when told to, not in the background as other processes happen.
With background refresh disabled, your VBA procedure will wait for your external data to refresh before moving to the next line of code.
Then you just modify the following code:
ActiveWorkbook.Connections("CONNECTION_NAME").Refresh
Sheets("SHEET_NAME").PivotTables("PIVOT_TABLE_NAME").PivotCache.Refresh
You can also turn off background refresh in VBA:
ActiveWorkbook.Connections("CONNECTION_NAME").ODBCConnection.BackgroundQuery = False
You are sending a POST AJAX request so use $albumname = $_POST['album'];
on your server to fetch the value. Also I would recommend you writing the request like this in order to ensure proper encoding:
$.ajax({
type: 'POST',
url: 'test.php',
data: { album: this.title },
success: function(response) {
content.html(response);
}
});
or in its shorter form:
$.post('test.php', { album: this.title }, function() {
content.html(response);
});
and if you wanted to use a GET request:
$.ajax({
type: 'GET',
url: 'test.php',
data: { album: this.title },
success: function(response) {
content.html(response);
}
});
or in its shorter form:
$.get('test.php', { album: this.title }, function() {
content.html(response);
});
and now on your server you wil be able to use $albumname = $_GET['album'];
. Be careful though with AJAX GET requests as they might be cached by some browsers. To avoid caching them you could set the cache: false
setting.
Most of the answer is in existing replies, but for me not quite. This is what works for me with java.net.HttpURLConnection (I have tested all the cases with JDK 7 and JDK 8). Note that you do not have to use the Authenticator class.
Case 1 : Proxy without user authentication, access HTTP resources
-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=myport
Case 2 : Proxy with user authentication, access HTTP resources
-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=myport -Dhttps.proxyUser=myuser -Dhttps.proxyPassword=mypass
Case 3 : Proxy without user authentication, access HTTPS resources (SSL)
-Dhttps.proxyHost=myproxy -Dhttps.proxyPort=myport
Case 4 : Proxy with user authentication, access HTTPS resources (SSL)
-Dhttps.proxyHost=myproxy -Dhttps.proxyPort=myport -Dhttps.proxyUser=myuser -Dhttps.proxyPassword=mypass
Case 5 : Proxy without user authentication, access both HTTP and HTTPS resources (SSL)
-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=myport -Dhttps.proxyHost=myproxy -Dhttps.proxyPort=myport
Case 6 : Proxy with user authentication, access both HTTP and HTTPS resources (SSL)
-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=myport -Dhttp.proxyUser=myuser -Dhttp.proxyPassword=mypass -Dhttps.proxyHost=myproxy -Dhttps.proxyPort=myport -Dhttps.proxyUser=myuser -Dhttps.proxyPassword=mypass
You can set the properties in the with System.setProperty("key", "value) too.
To access HTTPS resource you may have to trust the resource by downloading the server certificate and saving it in a trust store and then using that trust store. ie
System.setProperty("javax.net.ssl.trustStore", "c:/temp/cert-factory/my-cacerts");
System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
You need to pass the variable into the function:
$data = 'My data';
function menugen($data)
{
echo $data;
}
Without favouring any particular naming choice, remember that a git repo can be cloned into any root directory of your choice:
git clone https://github.com/user/repo.git myDir
Here repo.git
would be cloned into the myDir
directory.
So even if your naming convention for a public repo ended up to be slightly incorrect, it would still be possible to fix it on the client side.
That is why, in a distributed environment where any client can do whatever he/she wants, there isn't really a naming convention for Git repo.
(except to reserve "xxx.git
" for bare form of the repo 'xxx
')
There might be naming convention for REST service (similar to "Are there any naming convention guidelines for REST APIs?"), but that is a separate issue.
pylab.show()
works but blocks (you need to close the window).
A much more convenient solution is to do pylab.ion()
(interactive mode on) when you start: all (the pylab equivalents of) pyplot.*
commands display their plot immediately. More information on the interactive mode can be found on the official web site.
I also second using the even more convenient ipython -pylab
(--pylab
, in newer versions), which allows you to skip the from … import …
part (%pylab
works, too, in newer IPython versions).
I did this in Excel 2000.
This statement should be: ms = Round(temp - Int(temp), 3) * 1000
You need to create a custom format for the result cell of [h]:mm:ss.000
