While making image with fully transparent background in PNG-8, the outline of the image looks prominent with little white bits. But in PNG-24 the outline is gone and looks perfect. Transparency in PNG-24 is greater and cleaner than PNG-8.
PNG-8 contains 256 colors, while PNG-24 contains 16 million colors.
File size is almost double in PNG-24 than PNG-8.
Yes but ....
Ruby passes a reference to an object and since everything in ruby is an object, then you could say it's pass by reference.
I don't agree with the postings here claiming it's pass by value, that seems like pedantic, symantic games to me.
However, in effect it "hides" the behaviour because most of the operations ruby provides "out of the box" - for example string operations, produce a copy of the object:
> astringobject = "lowercase"
> bstringobject = astringobject.upcase
> # bstringobject is a new object created by String.upcase
> puts astringobject
lowercase
> puts bstringobject
LOWERCASE
This means that much of the time, the original object is left unchanged giving the appearance that ruby is "pass by value".
Of course when designing your own classes, an understanding of the details of this behaviour is important for both functional behaviour, memory efficiency and performance.
All the methods are actually discouraged, it's a warning in Netbeans 7.4 and it surely is a good practice not to access superglobal variables directly, use a filter instead
$fromPerson = filter_input(INPUT_POST, 'fromPerson', FILTER_DEFAULT);
if($fromPerson === NULL) { /*$fromPerson is not present*/ }
else{ /*present*/ }
var_dump($fromPerson);exit(0);
NestedScrollView
as the name suggests is used when there is a need for a scrolling view inside another scrolling view. Normally this would be difficult to accomplish since the system would be unable to decide which view to scroll.
This is where NestedScrollView
comes in.
What I would do:
char c;
int cint;
for(int n = 0; n < str.length(); n ++;)
{
c = str.charAt(n);
cint = (int)c;
if(cint <48 || (cint > 57 && cint < 65) || (cint > 90 && cint < 97) || cint > 122)
{
specialCharacterCount++
}
}
That is a simple way to do things, without having to import any special classes. Stick it in a method, or put it straight into the main code.

I had the same error today, with XCode 6.1
What I found was that, no matter what I tried, I couldn't get XCode to stop complaining about this Provisioning Profile with a GUID as its name.
The solution was to search for this GUID in the .pbxproj file, which lives within the XCode .xcodeproj folder.
Just find the line containing your GUID:
PROVISIONING_PROFILE = "A9234343-.....34"
and change it to:
PROVISIONING_PROFILE = ""
One other thing to check: Your XCode PROJECT settings contain your Provisioning Profile & Code Signing settings, but, there is a second set under your project's "TARGETS" tab.
So, if XCode is complaining about a Provisioning Profile which isn't the one quoted in your project settings, then go have have a look at the settings shown under "TARGETS" in your XCode project.
(I wish someone had given me this advice, 4 painful hours ago..)
I always use a regular expression for checking for an empty string, dating back to CGI/Perl days, and also with Javascript, so why not with PHP as well, e.g. (albeit untested)
return preg_match('/\S/', $input);
Where \S represents any non-whitespace character
You can use Snapkit to set constraints programmatically.
class ViewController: UIViewController {
let rectView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
override func viewDidLoad() {
super.viewDidLoad()
setupViews()
}
private func setupViews() {
rectView.backgroundColor = .red
view.addSubview(rectView)
rectView.snp.makeConstraints {
$0.center.equalToSuperview()
}
}
}
You just got the answer for a normally servlet. However, I want to share you about something about Servlet 3.0
What is first a Servlet?
A servlet is a Web component that is managed by a container and generates dynamic content. Servlets are Java classes that are compiled to byte code that can be loaded dynamically into and run by a Java technology-enabled Web server or Servlet container.
Servlet 3.0 is an update to the existing Servlet 2.5 specification. Servlet 3.0 required API of the Java Platform, Enterprise Edition 6. Servlet 3.0 is focussed on extensibility and web framework pluggability. Servlet 3.0 bring you up some extensions such as Ease of Development (EoD), Pluggability, Async Support and Security Enhancements
Ease of Development
You can declare Servlets, Filter, Listeners, Init Params, and almost everything can be configured by using annotations
Pluggability
You can create a sub-project or a module with a web-fragment.xml. It means that it allows to implement pluggable functional requirements independently.
Async Support
Servlet 3.0 provides the ability of asynchronous processing, for example: Waiting for a resource to become available, Generating response asynchronously.
Security Enhancements
Support for the authenticate, login and logout servlet security methods
I found it from Java Servlet Tutorial
You need to use the DataGridViewColumn.AutoSizeMode
property.
You can use one of these values for column 0 and 1:
AllCells: The column width adjusts to fit the contents of all cells in the column, including the header cell.
AllCellsExceptHeader: The column width adjusts to fit the contents of all cells in the column, excluding the header cell.
DisplayedCells: The column width adjusts to fit the contents of all cells in the column that are in rows currently displayed onscreen, including the header cell.
DisplayedCellsExceptHeader: The column width adjusts to fit the contents of all cells in the column that are in rows currently displayed onscreen, excluding the header cell.
Then you use the Fill value for column 2
The column width adjusts so that the widths of all columns exactly fills the display area of the control...
this.DataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
As pointed out by other users, the default value can be set at datagridview
level with DataGridView.AutoSizeColumnsMode
property.
this.DataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
could be:
this.DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells;
Important note:
If your grid is bound to a datasource and columns are auto-generated (AutoGenerateColumns
property set to True), you need to use the DataBindingComplete
event to apply style AFTER columns have been created.
In some scenarios (change cells value by code for example), I had to call DataGridView1.AutoResizeColumns();
to refresh the grid.
So, there is no difference between MySQL "database" and MySQL "schema": these are two names for the same thing - a namespace for tables and other DB objects.
For people with Oracle background: MySQL "database" a.k.a. MySQL "schema" corresponds to Oracle schema. The difference between MySQL and Oracle CREATE SCHEMA commands is that in Oracle the CREATE SCHEMA command does not actually create a schema but rather populates it with tables and views. And Oracle's CREATE DATABASE command does a very different thing than its MySQL counterpart.

The following simple way to create radio button in your iOS app follow two steps.
Step1- Put this code in your in viewDidLoad or any other desired method
[_mrRadio setSelected:YES];
[_mrRadio setTag:1];
[_msRadio setTag:1];
[_mrRadio setBackgroundImage:[UIImage imageNamed:@"radiodselect_white.png"] forState:UIControlStateNormal];
[_mrRadio setBackgroundImage:[UIImage imageNamed:@"radioselect_white.png"] forState:UIControlStateSelected];
[_mrRadio addTarget:self action:@selector(radioButtonSelected:) forControlEvents:UIControlEventTouchUpInside];
[_msRadio setBackgroundImage:[UIImage imageNamed:@"radiodselect_white.png"] forState:UIControlStateNormal];
[_msRadio setBackgroundImage:[UIImage imageNamed:@"radioselect_white.png"] forState:UIControlStateSelected];
[_msRadio addTarget:self action:@selector(radioButtonSelected:) forControlEvents:UIControlEventTouchUpInside];
Step2- Put following IBAction method in your class
-(void)radioButtonSelected:(id)sender
{
switch ([sender tag ]) {
case 1:
if ([_mrRadio isSelected]==YES) {
// [_mrRadio setSelected:NO];
// [_msRadio setSelected:YES];
genderType = @"1";
}
else
{
[_mrRadio setSelected:YES];
[_msRadio setSelected:NO];
genderType = @"1";
}
break;
case 2:
if ([_msRadio isSelected]==YES) {
// [_msRadio setSelected:NO];
// [_mrRadio setSelected:YES];
genderType = @"2";
}
else
{
[_msRadio setSelected:YES];
[_mrRadio setSelected:NO];
genderType = @"2";
}
break;
default:
break;
}
}
In its article Constants (C# Programming Guide), Microsoft gives the following example:
class Calendar3
{
const int months = 12;
const int weeks = 52;
const int days = 365;
const double daysPerWeek = (double) days / (double) weeks;
const double daysPerMonth = (double) days / (double) months;
}
So, for constants, it appears that Microsoft is recommending the use of camelCasing
. But note that these constants are defined locally.
Arguably, the naming of externally-visible constants is of greater interest. In practice, Microsoft documents its public constants in the .NET class library as fields. Here are some examples:
static readonly
)The first two are examples of PascalCasing
. The third appears to follow Microsoft's Capitalization Conventions for a two-letter acronym (although pi is not an acryonym). And the fourth one seems to suggest that the rule for a two-letter acryonym extends to a single letter acronym or identifier such as E
(which represents the mathematical constant e).
Furthermore, in its Capitalization Conventions document, Microsoft very directly states that field identifiers should be named via PascalCasing
and gives the following examples for MessageQueue.InfiniteTimeout and UInt32.Min:
public class MessageQueue
{
public static readonly TimeSpan InfiniteTimeout;
}
public struct UInt32
{
public const Min = 0;
}
Conclusion: Use PascalCasing
for public constants (which are documented as const
or static readonly
fields).
Finally, as far as I know, Microsoft does not advocate specific naming or capitalization conventions for private identifiers as shown in the examples presented in the question.

So that I can ask it to get me the content/text in the div tag with class='container' contained within the body tag, Or something similar.
try:
from BeautifulSoup import BeautifulSoup
except ImportError:
from bs4 import BeautifulSoup
html = #the HTML code you've written above
parsed_html = BeautifulSoup(html)
print(parsed_html.body.find('div', attrs={'class':'container'}).text)
You don't need performance descriptions I guess - just read how BeautifulSoup works. Look at its official documentation.
I think what you might be after (as a literal implementation of your question), is:
public class TokenTree
{
public TokenTree()
{
tree = new Dictionary<string, IDictionary<string,string>>();
}
IDictionary<string, IDictionary<string, string>> tree;
}
You did actually say a "list" of key-values in your question, so you might want to swap the inner IDictionary
with a:
IList<KeyValuePair<string, string>>
You can simply make the start_date required using
<input type="submit" value="Submit" required />
You don't even need the checkform() then.

You can achieve a fade effect (instead of sticking with the default slide) using css only. Add these to your stylesheet
.carousel .item {
-webkit-transition: opacity 3s;
-moz-transition: opacity 3s;
-ms-transition: opacity 3s;
-o-transition: opacity 3s;
transition: opacity 3s;
}
.carousel .active.left {
left:0;opacity:0;z-index:2;
}
.carousel .next {
left:0;opacity:1;z-index:1;
}

If you're using JQuery you can do:
$('#elementid').click();
you can use this:
find . -name '* *' | while read fname
do
new_fname=`echo $fname | tr " " "_"`
if [ -e $new_fname ]
then
echo "File $new_fname already exists. Not replacing $fname"
else
echo "Creating new file $new_fname to replace $fname"
mv "$fname" $new_fname
fi
done
first you can do with this style:
mda="/usr/mda"
if [ ! -L "${mda}" ]; then
echo "=> File doesn't exist"
fi
if you want to do it in more advanced style you can write it like below:
#!/bin/bash
mda="$1"
if [ -e "$1" ]; then
if [ ! -L "$1" ]
then
echo "you entry is not symlink"
else
echo "your entry is symlink"
fi
else
echo "=> File doesn't exist"
fi
the result of above is like:
root@linux:~# ./sym.sh /etc/passwd
you entry is not symlink
root@linux:~# ./sym.sh /usr/mda
your entry is symlink
root@linux:~# ./sym.sh
=> File doesn't exist
Things become complicated when you want to post files via multipart/form-data
, especially multiple binary files. Below is a working example:
const FormData = require('form-data')
const fs = require('fs')
const path = require('path')
const formData = new FormData()
formData.append('files[]', JSON.stringify({ to: [{ phoneNumber: process.env.RINGCENTRAL_RECEIVER }] }), 'test.json')
formData.append('files[]', fs.createReadStream(path.join(__dirname, 'test.png')), 'test.png')
await rc.post('/restapi/v1.0/account/~/extension/~/fax', formData, {
headers: formData.getHeaders()
})
headers: {'Content-Type': 'multipart/form-data' }
I prefer headers: formData.getHeaders()
async
and await
above, you can change them to plain Promise statements if you don't like themheaders: { ...yourHeaders, ...formData.getHeaders() }
Newly added content below:
Browser's FormData
is different from the NPM package 'form-data'. The following code works for me in browser:
HTML:
<input type="file" id="image" accept="image/png"/>
JavaScript:
const formData = new FormData()
// add a non-binary file
formData.append('files[]', new Blob(['{"hello": "world"}'], { type: 'application/json' }), 'request.json')
// add a binary file
const element = document.getElementById('image')
const file = element.files[0]
formData.append('files[]', file, file.name)
await rc.post('/restapi/v1.0/account/~/extension/~/fax', formData)

If you're running your PHP script from the command-line, passthru()
has one large benefit. It will let you execute scripts/programs such as vim
, dialog
, etc, letting those programs handle control and returning to your script only when they are done.
If you use system()
or exec()
to execute those scripts/programs, it simply won't work.
Gotcha: For some reason, you can't execute less
with passthru()
in PHP.

All the above answers technically answer the asker's question, but just thought I'd point out a case where you might encounter problems.
If you declare your struct like this:
typedef struct{
int x;
foo(){};
} foo;
You will have problems trying to declare a constructor. This is of course because you haven't actually declared a struct named "foo", you've created an anonymous struct and assigned it the alias "foo". This also means you will not be able to use "foo" with a scoping operator in a cpp file:
foo.h:
typedef struct{
int x;
void myFunc(int y);
} foo;
foo.cpp:
//<-- This will not work because the struct "foo" was never declared.
void foo::myFunc(int y)
{
//do something...
}
To fix this, you must either do this:
struct foo{
int x;
foo(){};
};
or this:
typedef struct foo{
int x;
foo(){};
} foo;
Where the latter creates a struct called "foo" and gives it the alias "foo" so you don't have to use the struct
keyword when referencing it.
To check if a Variant
is Null, you need to do it like:
Isnull(myvar) = True
or
Not Isnull(myvar)
If I understand you correctly, you need to use -SearchBase:
Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *
Note that Get-ADUser defaults to using
-SearchScope Subtree
so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).

With Postman, select Body tab and choose the raw option and type the following:
grant_type=password&username=yourusername&password=yourpassword
For development you can disable password policy if no other profile was set (i.e. disable password expiration in default one):
ALTER PROFILE "DEFAULT" LIMIT PASSWORD_VERIFY_FUNCTION NULL;
Then, reset password and unlock user account. It should never expire again:
alter user user_name identified by new_password account unlock;
You can update progress bar only from ProgressChanged
or RunWorkerCompleted
event handlers as these are synchronized with the UI thread.
The basic idea is. Thread.Sleep
just simulates some work here. Replace it with your real routing call.
public Form1()
{
InitializeComponent();
backgroundWorker1.DoWork += backgroundWorker1_DoWork;
backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged;
backgroundWorker1.WorkerReportsProgress = true;
}
private void button1_Click(object sender, EventArgs e)
{
backgroundWorker1.RunWorkerAsync();
}
private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
for (int i = 0; i < 100; i++)
{
Thread.Sleep(1000);
backgroundWorker1.ReportProgress(i);
}
}
private void backgroundWorker1_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
progressBar1.Value = e.ProgressPercentage;
}
Even after going through many posts, it took several hours to figure out the problem. Here is the detailed approach written in simple language to run python via command line in windows.
1. Download executable file from python.org
Choose the latest version and download Windows-executable installer. Execute the downloaded file and let installation complete.
2. Ensure the file is downloaded in some administrator folder
3. Update the system PATH variable This is the most crucial step and there are two ways to do this:- (Follow the second one preferably)
1. MANUALLY
- Search for 'Edit the system Environment Variables' in the search bar.(WINDOWS 10)
- In the System Properties dialog, navigate to "Environment Variables".
- In the Environment Variables dialog look for "Path" under the System Variables window. (# Ensure to click on Path under bottom window named System Variables and not under user variables)
- Edit the Path Variable by adding location of Python37/ PythonXX folder. I added following line:-
" ;C:\Program Files (x86)\Python37;C:\Program Files (x86)\Python37\Scripts "
- Click Ok and close the dialogs.
2. SCRIPTED
- Open the command prompt and navigate to Python37/XX folder using cd command.
- Write the following statement:-
"python.exe Tools\Scripts\win_add2path.py"
You can now use python in the command prompt:)
1. Using Shell
Type python in cmd and use it.
2. Executing a .py file
Type python filename.py to execute it.
The easiest way is to create a container for the canvas and set its height:
<div style="height: 300px">
<canvas id="chart"></canvas>
</div>
and set
options: {
responsive: true,
maintainAspectRatio: false
}
Here is the way I look at COALESCE...and hopefully it makes sense...
In a simplistic form….
Coalesce(FieldName, 'Empty')
So this translates to…If "FieldName" is NULL, populate the field value with the word "EMPTY".
Now for mutliple values...
Coalesce(FieldName1, FieldName2, Value2, Value3)
If the value in Fieldname1 is null, fill it with the value in Fieldname2, if FieldName2 is NULL, fill it with Value2, etc.
This piece of test code for the AdventureWorks2012 sample database works perfectly & gives a good visual explanation of how COALESCE works:
SELECT Name, Class, Color, ProductNumber,
COALESCE(Class, Color, ProductNumber) AS FirstNotNull
FROM Production.Product
The easiest way to do this is generate a KML file (see http://code.google.com/apis/kml/articles/csvtokml.html for a possible solution). You can then open that up in Google Maps by storing it online and linking to it from Google Maps as described at http://code.google.com/apis/kml/documentation/whatiskml.html
EDIT: http://www.gpsbabel.org/ may let you do it without coding.
I recommend http://stacktrace.sourceforge.net/ project. It support Windows, Mac OS and also Linux
Also, I add to do the following steps so that the git repo would be correctly linked with the IDE:
$ git reset <commit #>
$ git checkout <file/path>

You can use the strdup
function which has the following prototype
char *strdup(const char *s1);
Example of use:
#include <string.h>
char * my_str = strdup("My string literal!");
char * my_other_str = strdup(some_const_str);
or strcpy/strncpy to your buffer
or rewrite your functions to use const char *
as parameter instead of char *
where possible so you can preserve the const
What do you want to fade? The background
or color
attribute?
Currently you're changing the background color, but telling it to transition the color property. You can use all
to transition all properties.
.clicker {
-moz-transition: all .2s ease-in;
-o-transition: all .2s ease-in;
-webkit-transition: all .2s ease-in;
transition: all .2s ease-in;
background: #f5f5f5;
padding: 20px;
}
.clicker:hover {
background: #eee;
}
Otherwise just use transition: background .2s ease-in
.
I had a similar problem and solved it by combining the answers above
class FeedPost extends React.Component {
constructor(props) {
...
this.handleLayoutChange = this.handleLayoutChange.bind(this);
}
handleLayoutChange() {
this.feedPost.measure( (fx, fy, width, height, px, py) => {
console.log('Component width is: ' + width)
console.log('Component height is: ' + height)
console.log('X offset to page: ' + px)
console.log('Y offset to page: ' + py)
})
}
render {
return(
<View onLayout={(event) => {this.handleLayoutChange(event) }}
ref={view => { this.feedPost = view; }} >
...
Now I can see the position of my feedPost element in the logs:
08-24 11:15:36.838 3727 27838 I ReactNativeJS: Component width is: 156
08-24 11:15:36.838 3727 27838 I ReactNativeJS: Component height is: 206
08-24 11:15:36.838 3727 27838 I ReactNativeJS: X offset to page: 188
08-24 11:15:36.838 3727 27838 I ReactNativeJS: Y offset to page: 870
It can also be as simple as this.

Most answers suggest appending '%' at the end. I would rather prefer Intl.NumberFormat()
with { style: 'percent'}

_x000D_
var option = {_x000D_

This is my simplified example of how to run RAW SELECT, get result and access the values.
$res = DB::select('
select count(id) as c
from prices p
where p.type in (2,3)
');
if ($res[0]->c > 10)
{
throw new Exception('WOW');
}
If you want only run sql script with no return resutl use this
DB::statement('ALTER TABLE products MODIFY COLUMN physical tinyint(1) AFTER points;');

Decorators seem better suited to modify the functionality of an entire object (including function objects) versus the functionality of an object method which in general will depend on instance attributes. For example:
def mod_bar(cls):
# returns modified class
def decorate(fcn):
# returns decorated function
def new_fcn(self):
print self.start_str
print fcn(self)
print self.end_str
return new_fcn
cls.bar = decorate(cls.bar)
return cls
@mod_bar
class Test(object):
def __init__(self):
self.start_str = "starting dec"
self.end_str = "ending dec"
def bar(self):
return "bar"
The output is:
>>> import Test
>>> a = Test()
>>> a.bar()
starting dec
bar
ending dec
$(document).ready(function(){
$('#shares').val('');
});
You need to make sure images come first and put in a comma after the background image call. then it actually does work:
background:url(egg.png) no-repeat 70px 2px #82d4fe; /* Old browsers */
background:url(egg.png) no-repeat 70px 2px, -moz-linear-gradient(top, #82d4fe 0%, #1db2ff 78%) ; /* FF3.6+ */
background:url(egg.png) no-repeat 70px 2px, -webkit-gradient(linear, left top, left bottom, color-stop(0%,#82d4fe), color-stop(78%,#1db2ff)); /* Chrome,Safari4+ */
background:url(egg.png) no-repeat 70px 2px, -webkit-linear-gradient(top, #82d4fe 0%,#1db2ff 78%); /* Chrome10+,Safari5.1+ */
background:url(egg.png) no-repeat 70px 2px, -o-linear-gradient(top, #82d4fe 0%,#1db2ff 78%); /* Opera11.10+ */
background:url(egg.png) no-repeat 70px 2px, -ms-linear-gradient(top, #82d4fe 0%,#1db2ff 78%); /* IE10+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#82d4fe', endColorstr='#1db2ff',GradientType=0 ); /* IE6-9 */
background:url(egg.png) no-repeat 70px 2px, linear-gradient(top, #82d4fe 0%,#1db2ff 78%); /* W3C */
This is an addition to Josh's answer.
You can also keep the values of other variables while filtering out duplicated rows in data.table
Example:
library(data.table)
#create data table
dt <- data.table(
V1=LETTERS[c(1,1,1,1,2,3,3,5,7,1)],
V2=LETTERS[c(2,3,4,2,1,4,4,6,7,2)],
V3=c(1),
V4=c(2) )
> dt
# V1 V2 V3 V4
# A B 1 2
# A C 1 2
# A D 1 2
# A B 1 2
# B A 1 2
# C D 1 2
# C D 1 2
# E F 1 2
# G G 1 2
# A B 1 2
# set the key to all columns
setkey(dt)
# Get Unique lines in the data table
unique( dt[list(V1, V2), nomatch = 0] )
# V1 V2 V3 V4
# A B 1 2
# A C 1 2
# A D 1 2
# B A 1 2
# C D 1 2
# E F 1 2
# G G 1 2
Alert: If there are different combinations of values in the other variables, then your result will be
unique combination of V1 and V2
Try those methods, it should work:
Update 11/2020: The Google Developer link is (currently) dead. The original article with a LOT more explanations can still be found at web.archive.org.
This question is already a few years old but in that time some additional possibilities have evolved, like accessing the camera directly, displaying a preview and capturing snapshots (e.g. for QR code scanning).
This Google Developers article provides an in-depth explaination of all (?) the ways how to get image/camera data into a web application, from "work everywhere" (even in desktop browsers) to "work only on modern, up-to-date mobile devices with camera". Along with many useful tips.
Explained methods:
Ask for a URL: Easiest but least satisfying.
File input (covered by most other posts here): The data can then be attached to a or manipulated with JavaScript by listening for an onchange event on the input element and then reading the files property of the event target.
<input type="file" accept="image/*" id="file-input">
<script>
const fileInput = document.getElementById('file-input');
fileInput.addEventListener('change', (e) => doSomethingWithFiles(e.target.files));
</script>
The files
property is a FileList object.
<div id="target">You can drag an image file here</div>
<script>
const target = document.getElementById('target');
target.addEventListener('drop', (e) => {
e.stopPropagation();
e.preventDefault();
doSomethingWithFiles(e.dataTransfer.files);
});
target.addEventListener('dragover', (e) => {
e.stopPropagation();
e.preventDefault();
e.dataTransfer.dropEffect = 'copy';
});
</script>
You can get a FileList
object from the dataTransfer.files
property of the drop
event.
<textarea id="target">Paste an image here</textarea>
<script>
const target = document.getElementById('target');
target.addEventListener('paste', (e) => {
e.preventDefault();
doSomethingWithFiles(e.clipboardData.files);
});
</script>
e.clipboardData.files
is a FileList
object again.
const supported = 'mediaDevices' in navigator;
and prompt the user for consent. Then show a realtime preview and copy snapshots to a canvas.<video id="player" controls autoplay></video>
<button id="capture">Capture</button>
<canvas id="canvas" width=320 height=240></canvas>
<script>
const player = document.getElementById('player');
const canvas = document.getElementById('canvas');
const context = canvas.getContext('2d');
const captureButton = document.getElementById('capture');
const constraints = {
video: true,
};
captureButton.addEventListener('click', () => {
// Draw the video frame to the canvas.
context.drawImage(player, 0, 0, canvas.width, canvas.height);
});
// Attach the video stream to the video element and autoplay.
navigator.mediaDevices.getUserMedia(constraints)
.then((stream) => {
player.srcObject = stream;
});
</script>
Don't forget to stop the video stream with
player.srcObject.getVideoTracks().forEach(track => track.stop());

Is sharding mostly important in very large scale applications or does it apply to smaller scale ones?
Sharding is a concern if and only if your needs scale past what can be served by a single database server. It's a swell tool if you have shardable data and you have incredibly high scalability and performance requirements. I would guess that in my entire 12 years I've been a software professional, I've encountered one situation that could have benefited from sharding. It's an advanced technique with very limited applicability.
Besides, the future is probably going to be something fun and exciting like a massive object "cloud" that erases all potential performance limitations, right? :)
You can pass the parent´s stdio to the child process if that´s what you want:
require('child_process').execSync(
'rsync -avAXz --info=progress2 "/src" "/dest"',
{stdio: 'inherit'}
);
Another simple solution is to define your onClickListener, in the getView(..) method, of your ListAdapter.
public View getView(final int position, View convertView, ViewGroup parent){
//initialise your view
...
View row = context.getLayoutInflater().inflate(R.layout.list_item, null);
...
//define your listener on inner items
//define your global listener
row.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
doSomethingWithViewAndPosition(v,position);
}
});
return row;
That way your row are clickable, and your inner view too :)
for the most basic read of a text file, use open
example:
Dim FileNum As Integer
Dim DataLine As String
FileNum = FreeFile()
Open "Filename" For Input As #FileNum
While Not EOF(FileNum)
Line Input #FileNum, DataLine ' read in data 1 line at a time
' decide what to do with dataline,
' depending on what processing you need to do for each case

On windows use the name of the table in quotes:
TABLE "user";
or SELECT * FROM "user";
For Xamarin Android this was the only solution that worked for me: another stack overflow post
If you are using AndroidClientHandler
, you need to supply a SSLSocketFactory
and a custom implementation of HostnameVerifier
with all checks disabled. To do this, you’ll need to subclass AndroidClientHandler
and override the appropriate methods.
internal class BypassHostnameVerifier : Java.Lang.Object, IHostnameVerifier
{
public bool Verify(string hostname, ISSLSession session)
{
return true;
}
}
internal class InsecureAndroidClientHandler : AndroidClientHandler
{
protected override SSLSocketFactory ConfigureCustomSSLSocketFactory(HttpsURLConnection connection)
{
return SSLCertificateSocketFactory.GetInsecure(1000, null);
}
protected override IHostnameVerifier GetSSLHostnameVerifier(HttpsURLConnection connection)
{
return new BypassHostnameVerifier();
}
}
And then
var httpClient = new System.Net.Http.HttpClient(new InsecureAndroidClientHandler());
Check an ASCII table.
It stands for CR
, or Carriage Return, AKA the Return key.
It is not only the table cell which is growing, the table itself can grow, too. To avoid this you can assign a fixed width to the table which in return forces the cell width to be respected:
table {
table-layout: fixed;
width: 120px; /* Important */
}
td {
width: 30px;
}
(Using overflow: hidden
and/or text-overflow: ellipsis
is optional but highly recommended for a better visual experience)
So if your situation allows you to assign a fixed width to your table, this solution might be a better alternative to the other given answers (which do work with or without a fixed width)
In most modern browsers, you can now specify:
<table>
<colgroup>
<col width="100px" />
<col width="200px" />
<col width="145px" />
</colgroup>
<thead>
<tr>
<th>My 100px header</th>
<th>My 200px header</th>
<th>My 145px header</th>
</tr>
</thead>
<tbody>
<td>100px is all you get - anything more hides due to overflow.</td>
<td>200px is all you get - anything more hides due to overflow.</td>
<td>100px is all you get - anything more hides due to overflow.</td>
</tbody>
</table>
Then if you apply the styles from the posts above, as follows:
table {
table-layout: fixed; /* This enforces the "col" widths. */
}
table th, table td {
overflow: hidden;
white-space: nowrap;
}
The result gives you nicely hidden overflow throughout the table. Works in latest Chrome, Safari, Firefox and IE. I haven't tested in IE prior to 9 - but my guess is that it will work back as far as 7, and you might even get lucky enough to see 5.5 or 6 support. ;)
You can shorten JSprangs solution a bit by using a method group instead:
string s1 = "1;2;3;4;5;6;7;8;9;10;11;12";
int[] ints = s1.Split(';').Select(int.Parse).ToArray();
If you have IE8 installed in your machine, you can test how your site works in IE7 too. When you are in the page you need to test in IE7 browser, Open "Tools"->"developer tools". And then in the menu of that "Developer tools" dialog box, Click on "Browser Mode:[CURRENT MODE]" and there you can select 3 options. that is,
try this one its worked for me
$(document).ready(function(e){_x000D_

As a general rule, you can’t just set the color of a horizontal line with CSS like you would anything else. First of all, Internet Explorer needs the color in your CSS to read like this:
“color: #123455”
But Opera and Mozilla needs the color in your CSS to read like this:
“background-color: #123455”
So, you will need to add both options to your CSS.
Next, you will need to give the horizontal line some dimensions or it will default to the standard height, width and color set by your browser. Here is a sample code of what your CSS should look like to get the blue horizontal line.
hr {
border: 0;
width: 100%;
color: #123455;
background-color: #123455;
height: 5px;
}
Or you could just add the style to your HTML page directly when you insert a horizontal line, like this:
<hr style="background:#123455" />
Hope this helps.

Using the solution showed in this question, System.Windows.Forms.Clipboard.SetText(...)
, results in the exception:
Current thread must be set to single thread apartment (STA) mode before OLE calls can be made
To prevent this, you can add the attribute:
[STAThread]
to
static void Main(string[] args)
Without any SMTP server sending mail,use this code for sending mail....
click below for mail sending code
listen guys first you can do this less secure your gmail account after send mail with your gmail account
You can use this php.ini setting
;smtp = smtp.gmail.com
;smtp-port = 25
;sendmail_from = my gmail is here
And sendmail.ini settings
smtp_server = smtp.gmail.com
smtp_port = 465
smtp_ssl = auto
auth_username = my gmail is here
auth_password = password
hostname = localhost
you can try this changes and i hope this code sent mail....
Below is an example of multiple figures that I used recently in Latex. You need to call these packages
\usepackage{graphicx}
\usepackage{subfig})
\begin{figure}[H]%
\centering
\subfloat[Row1]{{\includegraphics[scale=.36]{1.png} }}%
\subfloat[Row2]{{\includegraphics[scale=.36]{2.png} }}%
\subfloat[Row3]{{\includegraphics[scale=.36]{3.png} }}%
\hfill
\subfloat[Row4]{{\includegraphics[scale=0.37]{4.png} }}%
\subfloat[Row5]{{\includegraphics[scale=0.37]{5.png} }}%
\caption{Multiple figures in latex.}%

In SSMS in the Object Explorer, right click on the database, right-click and pick "Tasks" and then "Generate Scripts".
This will allow you to generate scripts for a single or all tables, and one of the options is "Script Data". If you set that to TRUE, the wizard will generate a script with INSERT INTO () statement for your data.
If using 2008 R2 or 2012 it is called something else, see screenshot below this one
Select "Types of Data to Script" which can be "Data Only", "Schema and Data" or "Schema Only" - the default).
And then there's a "SSMS Addin" Package on Codeplex (including source) which promises pretty much the same functionality and a few more (like quick find etc.)
Just right clic on the created connection and select "Schema browser", then use the filter to display the desired one.
Cheers.
This answer using Pandas is adapted from above, as rolling_mean
is not part of Pandas anymore
# the recommended syntax to import pandas
import pandas as pd
import numpy as np
# prepare some fake data:
# the date-time indices:
t = pd.date_range('1/1/2010', '12/31/2012', freq='D')
# the data:
x = np.arange(0, t.shape[0])
# combine the data & index into a Pandas 'Series' object
D = pd.Series(x, t)
Now, just call the function rolling
on the dataframe with a window size, which in my example below is 10 days.
d_mva10 = D.rolling(10).mean()
# d_mva is the same size as the original Series
# though obviously the first w values are NaN where w is the window size
d_mva10[:11]

This works for arrays, objects and primitives. Doubly recursive algorithm that switches between two traversal methods:
const deepClone = (objOrArray) => {
const copyArray = (arr) => {
let arrayResult = [];
arr.forEach(el => {
arrayResult.push(cloneObjOrArray(el));
});
return arrayResult;
}
const copyObj = (obj) => {
let objResult = {};
for (key in obj) {
if (obj.hasOwnProperty(key)) {
objResult[key] = cloneObjOrArray(obj[key]);
}
}
return objResult;
}
const cloneObjOrArray = (el) => {
if (Array.isArray(el)) {
return copyArray(el);
} else if (typeof el === 'object') {
return copyObj(el);
} else {
return el;
}
}
return cloneObjOrArray(objOrArray);
}
Here's a solution that uses k bits of extra storage, without any clever tricks and just straightforward. Execution time O (n), extra space O (k). Just to prove that this can be solved without reading up on the solution first or being a genius:
void puzzle (int* data, int n, bool* extra, int k)
{
// data contains n distinct numbers from 1 to n + k, extra provides
// space for k extra bits.
// Rearrange the array so there are (even) even numbers at the start
// and (odd) odd numbers at the end.
int even = 0, odd = 0;
while (even + odd < n)
{
if (data [even] % 2 == 0) ++even;
else if (data [n - 1 - odd] % 2 == 1) ++odd;
else { int tmp = data [even]; data [even] = data [n - 1 - odd];
data [n - 1 - odd] = tmp; ++even; ++odd; }
}
// Erase the lowest bits of all numbers and set the extra bits to 0.
for (int i = even; i < n; ++i) data [i] -= 1;
for (int i = 0; i < k; ++i) extra [i] = false;
// Set a bit for every number that is present
for (int i = 0; i < n; ++i)
{
int tmp = data [i];
tmp -= (tmp % 2);
if (i >= even) ++tmp;
if (tmp <= n) data [tmp - 1] += 1; else extra [tmp - n - 1] = true;
}
// Print out the missing ones
for (int i = 1; i <= n; ++i)
if (data [i - 1] % 2 == 0) printf ("Number %d is missing\n", i);
for (int i = n + 1; i <= n + k; ++i)
if (! extra [i - n - 1]) printf ("Number %d is missing\n", i);
// Restore the lowest bits again.
for (int i = 0; i < n; ++i) {
if (i < even) { if (data [i] % 2 != 0) data [i] -= 1; }
else { if (data [i] % 2 == 0) data [i] += 1; }
}
}
#!/bin/bash
read -p "Enter a directory: " BASEPATH
SUBFOLD1=${BASEPATH%%/}/subFold1
SUBFOLD2=${BASEPATH%%/}/subFold2
echo "I will create $SUBFOLD1 and $SUBFOLD2"
# mkdir -p $SUBFOLD1
# mkdir -p $SUBFOLD2
And if you want to use readline so you get completion and all that, add a -e
to the call to read
:
read -e -p "Enter a directory: " BASEPATH
You can bridge from String to NSString and convert from CInt to Int like this:
var myint: Int = Int(stringNumb.bridgeToObjectiveC().intValue)
Also add the key "StartingMonthColumn" in App.config that you run application from, for example in the App.config of the test project.
From mere curiosity, I timed the two rivalling answers posted above.
And I had the following results:
dateutil.parser (valid str): 4.6732222699938575
dateutil.parser (invalid str): 1.7270505399937974
datetime.strptime (valid): 0.7822393209935399
datetime.strptime (invalid): 0.4394566189876059
And here's the code I used (Python 3.6)
from dateutil import parser as date_parser
from datetime import datetime
from timeit import timeit
def is_date_parsing(date_str):
try:
return bool(date_parser.parse(date_str))
except ValueError:
return False
def is_date_matching(date_str):
try:
return bool(datetime.strptime(date_str, '%Y-%m-%d'))
except ValueError:
return False
if __name__ == '__main__':
print("dateutil.parser (valid date):", end=' ')
print(timeit("is_date_parsing('2021-01-26')",

colnames(df)[-1*(1:(ncol(df) - length(namevector)))] <- namevector
One advantage (albeit very slight) of defining string constants is that you can concatenate them at compile time:
#define HELLO "hello"
#define WORLD "world"
puts( HELLO WORLD );
Not sure that's really an advantage, but it is a technique that cannot be used with const char *
's.
Use &
SCSS
.container {
background:red;
color:white;
&.hello {
padding-left:50px;
}
}
https://sass-lang.com/documentation/style-rules/parent-selector
The best way in my eyes is to use the concat()
method provided by the String
class itself.
The useage would, in your case, look like this:
String myConcatedString = cursor.getString(numcol).concat('-').
concat(cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE)));
You could use crypto-js.
I would also recommend using SHA256, rather than MD5.
To install crypto-js via NPM:
npm install crypto-js
Alternatively you can use a CDN and reference the JS file.
Then to display a MD5 and SHA256 hash, you can do the following:
<script type="text/javascript">
var md5Hash = CryptoJS.MD5("Test");
var sha256Hash = CryptoJS.SHA256("Test1");
console.log(md5Hash.toString());
console.log(sha256Hash.toString());
</script>
Working example located here, JSFiddle
There are also other JS functions that will generate an MD5
hash, outlined below.
http://www.myersdaily.org/joseph/javascript/md5-text.html
http://pajhome.org.uk/crypt/md5/md5.html
function md5cycle(x, k) {
var a = x[0], b = x[1], c = x[2], d = x[3];
a = ff(a, b, c, d, k[0], 7, -680876936);
d = ff(d, a, b, c, k[1], 12, -389564586);
c = ff(c, d, a, b, k[2], 17, 606105819);
b = ff(b, c, d, a, k[3], 22, -1044525330);
a = ff(a, b, c, d, k[4], 7, -176418897);
d = ff(d, a, b, c, k[5], 12, 1200080426);

Consider also just doing mkdir -p data/images
in your Makefile, if the directory needs to be there during build.
If that's not good enough, just create an empty file in data/images and ignore data.
touch data/images/.gitignore
git add data/images/.gitignore
git commit -m "Add empty .gitignore to keep data/images around"
echo data >> .gitignore
git add .gitignore
git commit -m "Add data to .gitignore"
This question on StackOverflow deals with RadioButtonListFor and the answer addresses your question too. You can set the selected property in the RadioButtonListViewModel.
The same example for Node.js:

You can't use a function to insert data into a base table. Functions return data. This is listed as the very first limitation in the documentation:
User-defined functions cannot be used to perform actions that modify the database state.
"Modify the database state" includes changing any data in the database (though a table variable is an obvious exception the OP wouldn't have cared about 3 years ago - this table variable only lives for the duration of the function call and does not affect the underlying tables in any way).
You should be using a stored procedure, not a function.
I'm not with computer,so I write a draft. You might be clear of what I say.

for i,v:=range filesInfo{
if !v.IsDir() {
fileNames = append(fileNames, v.Name())
}
}
var fileNumber = len(fileNames)
var contents = make([]string, fileNumber, 10)
wg := sync.WaitGroup{}
wg.Add(fileNumber)
for i,_:=range content {
go func(i int){
defer wg.Done()
buf,e := ioutil.Readfile(fmt.Printf("%s/%s", dir, fileName[i]))
defer file.Close()
content[i] = string(buf)
}(i)
}
wg.Wait()
}
Use a regular expression for .replace()
.:

If those linebreaks were made by windows-encoding, you will also have to replace the carriage return

Based on different answers but mainly on this, this works for what I need:
UIImage *image1 = ...; // The image from where you want a pixel data
int pixelX = ...; // The X coordinate of the pixel you want to retrieve
int pixelY = ...; // The Y coordinate of the pixel you want to retrieve
uint32_t pixel1; // Where the pixel data is to be stored
CGContextRef context1 = CGBitmapContextCreate(&pixel1, 1, 1, 8, 4, CGColorSpaceCreateDeviceRGB(), kCGImageAlphaNoneSkipFirst);
CGContextDrawImage(context1, CGRectMake(-pixelX, -pixelY, CGImageGetWidth(image1.CGImage), CGImageGetHeight(image1.CGImage)), image1.CGImage);
CGContextRelease(context1);
As a result of this lines, you will have a pixel in AARRGGBB format with alpha always set to FF in the 4 byte unsigned integer pixel1
.

Well, I am still stumped. So here is more code.
Before I leave my map, I call SaveLocation(myMapView,myMapController);
This is what ends up calling my geocoding information.
But since getFromLocation
can throw an IOException
, I had to do the following to call SaveLocation
try
{
SaveLocation(myMapView,myMapController);
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
Then I have to change SaveLocation by saying it throws IOExceptions :
public void SaveLocation(MapView mv, MapController mc) throws IOException{
//I do this :
Geocoder myLocation = new Geocoder(getApplicationContext(), Locale.getDefault());
List myList = myLocation.getFromLocation(latPoint, lngPoint, 1);
//...
}
And it crashes every time.
If in case you are getting the values as undefined
, then you should consider restarting the node server and recompile again.
Why not do it?
var result= ctx.table.Where(x => x.UserName == "Value").FirstOrDefault();
if(result?.field == value)
{
// Match!
}
You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).
This is a good understanding of data-binding. I think you've got that down.
For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.
I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.
I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.
<div rotate-on-click="45"></div>
First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.
function rotate(deg, elem) {
$(elem).css({
webkitTransform: 'rotate('+deg+'deg)',
mozTransform: 'rotate('+deg+'deg)',
msTransform: 'rotate('+deg+'deg)',
oTransform: 'rotate('+deg+'deg)',
transform: 'rotate('+deg+'deg)'
});
}
function addRotateOnClick($elems) {
$elems.each(function(i, elem) {
var deg = 0;
$(elem).click(function() {
deg+= parseInt($(this).attr('rotate-on-click'), 10);
rotate(deg, this);
});
});
}
addRotateOnClick($('[rotate-on-click]'));
app.directive('rotateOnClick', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var deg = 0;
element.bind('click', function() {
deg+= parseInt(attrs.rotateOnClick, 10);
element.css({
webkitTransform: 'rotate('+deg+'deg)',
mozTransform: 'rotate('+deg+'deg)',
msTransform: 'rotate('+deg+'deg)',
oTransform: 'rotate('+deg+'deg)',
transform: 'rotate('+deg+'deg)'
});
});
}
};
});
Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link
function (or compile
function).
Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.
This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?
The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.
Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:
Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.
Here are some things that modern frameworks are providing:
Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.
If you need to destroy a planet and you have a Death Star, use the Death star.
Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.
In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:
<clock></clock>
Done.
Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.
Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.
THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.
Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.
Remove the if
keyword. It should just be predicate ? true_result : false_result
.
Also ? :
is called ternary operator.
Use fileReader.readAsDataURL( fileObject )
, this will encode it to base64, which you can safely upload to your server.
For what is worth:
the closest integer to any given input as shown in the following table can be calculated using Math.ceil or Math.floor depending of the distance between the input and the next integer
+-------+--------+
| input | output |
+-------+--------+
| 1 | 0 |
| 2 | 0 |
| 3 | 5 |
| 4 | 5 |
| 5 | 5 |
| 6 | 5 |
| 7 | 5 |
| 8 | 10 |
| 9 | 10 |
+-------+--------+
private int roundClosest(final int i, final int k) {
int deic = (i % k);
if (deic <= (k / 2.0)) {
return (int) (Math.floor(i / (double) k) * k);
} else {
return (int) (Math.ceil(i / (double) k) * k);
}
}
The easiest ways to do this would be:
System.out.println("\f");
System.out.println("\u000c");
As documented in ?legend
you do this like so:
plot(1:10,type = "n")
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",box.lwd = 0,box.col = "white",bg = "white")
points(1:10,1:10)
Line breaks are achieved with the new line character \n
. Making the points still visible is done simply by changing the order of plotting. Remember that plotting in R is like drawing on a piece of paper: each thing you plot will be placed on top of whatever's currently there.
Note that the legend text is cut off because I made the plot dimensions smaller (windows.options does not exist on all R platforms).
You can use the date.timetuple()
method and unpack operator *
.
args = d.timetuple()[:6]
datetime.datetime(*args)
I think that CONTAINS
took longer and used Merge
because you had a dash("-") in your query adventure-works.com
.
The dash is a break word so the CONTAINS
searched the full-text index for adventure
and than it searched for works.com
and merged the results.
When I needed something alike, ng-csv and other solutions here didn't completely help. My data was in $scope and there were no tables showing it. So, I built a directive to export given data to Excel using Sheet.js (xslsx.js) and FileSaver.js.
For example, the data is:
$scope.jsonToExport = [
{
"col1data": "1",
"col2data": "Fight Club",
"col3data": "Brad Pitt"
},
{
"col1data": "2",
"col2data": "Matrix Series",
"col3data": "Keanu Reeves"
},
{
"col1data": "3",
"col2data": "V for Vendetta",
"col3data": "Hugo Weaving"
}
];
I had to prepare data as array of arrays for my directive in my controller:
$scope.exportData = [];
// Headers:
$scope.exportData.push(["#", "Movie", "Actor"]);
// Data:
angular.forEach($scope.jsonToExport, function(value, key) {
$scope.exportData.push([value.col1data, value.col2data, value.col3data]);

What is the exact contents you are passing into $html_brand?
If it is has an invalid URL syntax, you will very likely get the HTTP code 0.
find
's optionsThere is actually no exec of /bin/ls
needed;
Find has an option that does just that:
find . -maxdepth 2 -type d -ls
To see only the one level of subdirectories you are interested in, add -mindepth
to the same level as -maxdepth
:
find . -mindepth 2 -maxdepth 2 -type d -ls
When the details that get shown should be different, -printf
can show any detail about a file in custom format;
To show the symbolic permissions and the owner name of the file, use -printf
with %M
and %u
in the format
.
I noticed later you want the full ownership information, which includes
the group. Use %g
in the format for the symbolic name, or %G
for the group id (like also %U
for numeric user id)
find . -mindepth 2 -maxdepth 2 -type d -printf '%M %u %g %p\n'
This should give you just the details you need, for just the right files.
I will give an example that shows actually different values for user and group:
$ sudo find /tmp -mindepth 2 -maxdepth 2 -type d -printf '%M %u %g %p\n'
drwx------ www-data www-data /tmp/user/33
drwx------ octopussy root /tmp/user/126
drwx------ root root /tmp/user/0
drwx------ siegel root /tmp/user/1000
drwxrwxrwt root root /tmp/systemd-[...].service-HRUQmm/tmp
(Edited for readability: indented, shortened last line)
Although the execution time is mostly irrelevant for this kind of command, increase in performance is large enough here to make it worth pointing it out:
Not only do we save creating a new process for each name - a huge task -
the information does not even need to be read, as find
already knows it.
What about using CSS3 transform
property and use scale
which ill give a zoom like effect, this can be done like so,
HTML
<div class="thumbnail">
<div class="image">
<img src="http://placehold.it/320x240" alt="Some awesome text"/>
</div>
</div>
CSS
.thumbnail {
width: 320px;
height: 240px;
}
.image {
width: 100%;
height: 100%;
}
.image img {
-webkit-transition: all 1s ease; /* Safari and Chrome */
-moz-transition: all 1s ease; /* Firefox */
-ms-transition: all 1s ease; /* IE 9 */
-o-transition: all 1s ease; /* Opera */
transition: all 1s ease;
}
.image:hover img {
-webkit-transform:scale(1.25); /* Safari and Chrome */
-moz-transform:scale(1.25); /* Firefox */
-ms-transform:scale(1.25); /* IE 9 */
-o-transform:scale(1.25); /* Opera */
transform:scale(1.25);
}
Here's a demo fiddle. I removed some of the element to make it simpler, you can always add overflow hidden to the .image
to hide the overflow of the scaled image.
zoom
property only works in IE
Use SimpleDateFormat
class. Take a look on its javadoc: it explains how to use format switches.
rapidjson is a C++ JSON parser/generator designed to be fast and small memory footprint.
There is a performance comparison with YAJL and JsonCPP.
Update:
I created an open source project Native JSON benchmark, which evaluates 29 (and increasing) C/C++ JSON libraries, in terms of conformance and performance. This should be an useful reference.
Using Bootstrap 3.3.5 and .container-fluid
, this is how I get full width with no gutters or horizontal scrolling on mobile. Note that .container-fluid
was re-introduced in 3.1.
Full width on mobile/tablet, 1/4 screen on desktop
<div class="container-fluid"> <!-- Adds 15px left/right padding -->
<div class="row"> <!-- Adds -15px left/right margins -->
<div class="col-md-4 col-md-offset-4" style="padding-left: 0, padding-right: 0"> <!-- col classes adds 15px padding, so remove the same amount -->
<!-- Full-width for mobile -->
<!-- 1/4 screen width for desktop -->
</div>
</div>
</div>
Full width on all resolutions (mobile, table, desktop)
<div class="container-fluid"> <!-- Adds 15px left/right padding -->
<div class="row"> <!-- Adds -15px left/right margins -->
<div>
<!-- Full-width content -->
</div>
</div>
</div>
All the data Git uses for information is stored in .git/
, so removing it should work just fine. Of course, make sure that your working copy is in the exact state that you want it, because everything else will be lost. .git
folder is hidden so make sure you turn on the Show hidden files, folders and disks
option.
From there, you can run git init
to create a fresh repository.
If you are using Java 8 you can encode the byte[]
by doing
MessageDigest digest = MessageDigest.getInstance("SHA-256");
byte[] hash = digest.digest(text.getBytes(StandardCharsets.UTF_8));
String encoded = Base64.getEncoder().encodeToString(hash);
I see in your code that you are trying to pass an ARRAY to POST action. In that case follow below working code -
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
function submitForm() {
var roles = ["role1", "role2", "role3"];
jQuery.ajax({
type: "POST",
url: "@Url.Action("AddUser")",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(roles),
success: function (data) { alert(data); },
failure: function (errMsg) {
alert(errMsg);
}
});
}
</script>
<input type="button" value="Click" onclick="submitForm()"/>
And the controller action is going to be -
public ActionResult AddUser(List<String> Roles)
{
return null;
}
Then when you click on the button -
If you have OS(64bit) and SSMS(64bit) and already install the AccessDatabaseEngine(64bit) and you still received an error, try this following solutions:
1: direct opening the sql server import and export wizard.
if you able to connect using direct sql server import and export wizard, then importing from SSMS is the issue, it's like activating 32bit if you import data from SSMS.
Instead of installing AccessDatabaseEngine(64bit) , try to use the AccessDatabaseEngine(32bit) , upon installation, windows will stop you for continuing the installation if you already have another app installed , if so , then use the following steps. This is from the MICROSOFT. The Quiet Installation.
If Office 365 is already installed, side by side detection will prevent the installation from proceeding. Instead perform a /quiet install of these components from command line. To do so, download the desired AccessDatabaseEngine.exe or AccessDatabaeEngine_x64.exe to your PC, open an administrative command prompt, and provide the installation path and switch Ex: C:\Files\AccessDatabaseEngine.exe /quiet

Action method needs to return FileResult with either a stream, byte[], or virtual path of the file. You will also need to know the content-type of the file being downloaded. Here is a sample (quick/dirty) utility method. Sample video link How to download files using asp.net core

Assuming that I
is your input image and F
is its Fourier Transform (i.e. F = fft2(I)
)
You can use this code:
F = fftshift(F); % Center FFT
F = abs(F); % Get the magnitude
F = log(F+1); % Use log, for perceptual scaling, and +1 since log(0) is undefined
F = mat2gray(F); % Use mat2gray to scale the image between 0 and 1
imshow(F,[]); % Display the result
var lat = homeMarker.getPosition().lat();
var lng = homeMarker.getPosition().lng();

In Java 8, it's a 1-liner via Files.find()
with an arbitrarily large depth (eg 999
) and BasicFileAttributes
of isRegularFile()
public static printFnames(String sDir) {
Files.find(Paths.get(sDir), 999, (p, bfa) -> bfa.isRegularFile()).forEach(System.out::println);
}
To add more filtering, enhance the lambda, for example all jpg files modified in the last 24 hours:
(p, bfa) -> bfa.isRegularFile()
&& p.getFileName().toString().matches(".*\\.jpg")
&& bfa.lastModifiedTime().toMillis() > System.currentMillis() - 86400000
You can achieve this issue also without extracting an array from the url
This is my alternative
var hasIndex = (document.location.href.search('index.html') === -1) ? doSomething() : doSomethingElse();

Here's a way using the switch
statement:
df <- data.frame(name = c('cow','pig','eagle','pigeon'),
stringsAsFactors = FALSE)
df$type <- sapply(df$name, switch,
cow = 'animal',
pig = 'animal',
eagle = 'bird',
pigeon = 'bird')
> df
name type
1 cow animal
2 pig animal
3 eagle bird
4 pigeon bird
The one downside of this is that you have to keep writing the category name (animal
, etc) for each item. It is syntactically more convenient to be able to define our categories as below (see the very similar question How do add a column in a data frame in R )
myMap <- list(animal = c('cow', 'pig'), bird = c('eagle', 'pigeon'))
and we want to somehow "invert" this mapping. I write my own invMap function:
invMap <- function(map) {
items <- as.character( unlist(map) )
nams <- unlist(Map(rep, names(map), sapply(map, length)))
names(nams) <- items
nams
}
and then invert the above map as follows:
> invMap(myMap)
cow pig eagle pigeon
"animal" "animal" "bird" "bird"
And then it's easy to use this to add the type
column in the data-frame:
df <- transform(df, type = invMap(myMap)[name])
> df
name type
1 cow animal
2 pig animal
3 eagle bird
4 pigeon bird
There are 5 cases for using the underscore in Python.
For storing the value of last expression in interpreter.
For ignoring the specific values. (so-called “I don’t care”)
To give special meanings and functions to name of variables or functions.
To use as ‘internationalization (i18n)’ or ‘localization (l10n)’ functions.
To separate the digits of number literal value.
Here is a nice article with examples by mingrammer.
WinSQL: I wanted to return all records for last month:
where DATE01 between dateadd(month,-1,dateadd(day,1,dateadd(day,-day(today()),today()))) and dateadd(day,-day(today()),today())
This does the same thing:
where month(DATE01) = month(dateadd(month,-1,today())) and year(DATE01) = year(dateadd(month,-1,today()))
An alternative method:

def getch():
fd = sys.stdin.fileno()
oldterm = termios.tcgetattr(fd)
newattr = termios.tcgetattr(fd)
newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
termios.tcsetattr(fd, termios.TCSANOW, newattr)
oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)
try:
while 1:
try:
c = sys.stdin.read(1)
break
except IOError: pass
finally:
termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)
return c

If you run pub build --mode=debug
the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug
is used.
Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline
Simplest of All Solutions:
Use:
filtered_df = df[(df['col1'] >= 1) & (df['col1'] <= 5)]

filtered_df = df[(df['year'] == 2018) & (df['month'] == 2)]
The default namespace in Python is "__main__"
. When you use import scipy
, Python creates a separate namespace as your module name.
The rule in Pyhton is: when you want to call an attribute from another namespaces you have to use the fully qualified attribute name.
Return data as XML
SELECT CONVERT(XML, [Data]) AS [Value]
FROM [dbo].[FormData]
WHERE [UID] LIKE '{my-uid}'
Make sure you set a reasonable limit in the SSMS options window, depending on the result you're expecting.
This will work if the text you're returning doesn't contain unencoded characters like &
instead of &
that will cause the XML conversion to fail.
Returning data using PowerShell
For this you will need the PowerShell SQL Server module installed on the machine on which you'll be running the command.
If you're all set up, configure and run the following script:
Invoke-Sqlcmd -Query "SELECT [Data] FROM [dbo].[FormData] WHERE [UID] LIKE '{my-uid}'" -ServerInstance "database-server-name" -Database "database-name" -Username "user" -Password "password" -MaxCharLength 10000000 | Out-File -filePath "C:\db_data.txt"
Make sure you set the -MaxCharLength
parameter to a value that suits your needs.
In my case, I was getting this error because I had an input named x
and I was creating (without realizing it) a local variable called x
. I thought I was trying to access an element of the input x
(which was an array), while I was actually trying to access an element of the local variable x
(which was a scalar).

You could also try putting your code in the Activated event of the form, if you want it to occur, just when the form is activated. You would need to put in a boolean "has executed" check though if it is only supposed to run on the first activation.
There's no built-in JavaScript function to do this, but you can write your own fairly easily:
function pad(n) {
return (n < 10) ? ("0" + n) : n;
}
Meanwhile there is a native JS function that does that. See String#padStart
console.log(String(5).padStart(2, '0'));

My guess is that ServiceUser.method()

In Visual Studio 2012, open the Options dialog (Tools -> Options). Under Environment -> General, the first setting is "Color theme." You can use this to switch between Light and Dark.
The shell theme is distinct from the editor theme--you can use any editor fonts and colors settings with either shell theme.
There is also a Color Theme Editor extension that can be used to create new themes.
It follows the convention that static methods should be thread-safe, but actually in v2 that static api is a proxy to an instance method on a default instance: in the case protobuf-net, it internally minimises contention points, and synchronises the internal state when necessary. Basically the library goes out of its way to do things right so that you can have simple code.

There are plenty of wonderful answers here already, but I wanted to throw in 1 more option for those wanting to add a new column to the original dataset that contains the number of times that row is repeated.
df1$counts <- sapply(X = paste(df1$Year, df1$Month),
FUN = function(x) { sum(paste(df1$Year, df1$Month) == x) })
The same could be accomplished by combining any of the above answers with the merge()
function.
As the other answers state:
count
will perform an SQL COUNT
querylength
will calculate the length of the resulting arraysize
will try to pick the most appropriate of the two to avoid excessive queriesBut there is one more thing. We noticed a case where size
acts differently to count
/length
altogether, and I thought I'd share it since it is rare enough to be overlooked.
If you use a :counter_cache
on a has_many
association, size
will use the cached count directly, and not make an extra query at all.
class Image < ActiveRecord::Base
belongs_to :product, counter_cache: true
end
class Product < ActiveRecord::Base
has_many :images
end
> product = Product.first # query, load product into memory
> product.images.size # no query, reads the :images_count column
> product.images.count # query, SQL COUNT
> product.images.length # query, loads images into memory
This behaviour is documented in the Rails Guides, but I either missed it the first time or forgot about it.
size
is inconsistent across different browsers and their possible font settings.
The width
style set in px will at least be consistent, modulo box-sizing issues. You might also want to set the style in ‘em’ if you want to size it relative to the font (though again, this will be inconsistent unless you set the input's font
family and size explicitly), or ‘%’ if you are making a liquid-layout form. Either way, a stylesheet is probably preferable to the inline style
attribute.
You still need size
for <select multiple>
to get the height to line up with the options properly. But I'd not use it on an <input>
.
You need to add the following to your module build.gradle file:
implementation 'com.google.android.material:material:1.0.0'
And use com.google.android.material.textfield.TextInputLayout in your XML:

You can also make an exception for leaving the page via submitting a particular form:
$(window).bind('beforeunload', function(){
return "Do you really want to leave now?";
});
$("#form_id").submit(function(){

Use the network byte order (big endian), which is the same as Java uses anyway. See man htons for the different translators in C.
You have a version conflict, please verify whether compiled version and JVM of Tomcat version are same. you can do it by examining tomcat startup .bat , looking for JAVA_HOME
You need to give a relative file path of <a href="../index.html">Home</a>
Alternately you can specify a link from the root of your site with
<a href="/pages/en/index.html">Home</a>
..
and .
have special meanings in file paths, ..
means up one directory and .
means current directory.
so <a href="index.html">Home</a>
is the same as <a href="./index.html">Home</a>

I could be wrong because I've never used Angular, but I believe you are probably using ng-bind
, which will create just a TextNode.
You will want to use ng-bind-html
instead.
http://docs.angularjs.org/api/ngSanitize.directive:ngBindHtml
Update: It looks like you'll need to use ng-bind-html-unsafe='q.category'
http://docs.angularjs.org/api/ng.directive:ngBindHtmlUnsafe
Here's a demo:
To use base_url()
(shorthand), you have to load the URL Helper
first
$this->load->helper('url');
Or you can autoload it by changing application/config/autoload.php
Or just use
$this->config->base_url();
Same applies to site_url()
.
Also I can see you are missing echo
(though its not your current problem), use the code below to solve the problem
<link rel="stylesheet" href="<?php echo base_url(); ?>css/default.css" type="text/css" />
With Google Gson you can use JsonParser:
import com.google.gson.JsonParser;
JsonParser parser = new JsonParser();
parser.parse(json_string); // throws JsonSyntaxException
Checking this morning it appears it is now:
socket.close()
With ASP.NET, you need to consider the reference point for a "relative URL" - is it relative to the page request, a user control, or if it is "relative" simply by virtue of using "~/"?
The Uri
class contains a simple way to convert a relative URL to an absolute URL (given an absolute URL as the reference point for the relative URL):
var uri = new Uri(absoluteUrl, relativeUrl);
If relativeUrl
is in fact an abolute URL, then the absoluteUrl
is ignored.
The only question then remains what the reference point is, and whether "~/" URLs are allowed (the Uri
constructor does not translate these).
Remember that the "folders/groups" you make in xcode, those which are yellowish are not reflected as real folders in your iPhone app. They are just there to structure your XCode project. You can nest as many yellow group as you want and they still only serve the purpose of organizing code in XCode.
Make a folder outside of XCode then drag it over, and select "Create folder references for any added folders" instead of "Create groups for any added folders" in the popup.
select MY_SEQ_NAME.currval from DUAL;
Keep in mind that it only works if you ran select MY_SEQ_NAME.nextval from DUAL;
in the current sessions.
Here is the simplest solution I can think of:
let rec distribute e = function
| [] -> [[e]]
| x::xs' as xs -> (e::xs)::[for xs in distribute e xs' -> x::xs]
let permute xs = Seq.fold (fun ps x -> List.collect (distribute x) ps) [[]] xs
The distribute
function takes a new element e
and an n
-element list and returns a list of n+1
lists each of which has e
inserted at a different place. For example, inserting 10
at each of the four possible places in the list [1;2;3]
:
> distribute 10 [1..3];;
val it : int list list =
[[10; 1; 2; 3]; [1; 10; 2; 3]; [1; 2; 10; 3]; [1; 2; 3; 10]]
The permute
function folds over each element in turn distributing over the permutations accumulated so far, culminating in all permutations. For example, the 6 permutations of the list [1;2;3]
:
> permute [1;2;3];;
val it : int list list =
[[3; 2; 1]; [2; 3; 1]; [2; 1; 3]; [3; 1; 2]; [1; 3; 2]; [1; 2; 3]]
Changing the fold
to a scan
in order to keep the intermediate accumulators sheds some light on how the permutations are generated an element at a time:
> Seq.scan (fun ps x -> List.collect (distribute x) ps) [[]] [1..3];;
val it : seq<int list list> =
seq
[[[]]; [[1]]; [[2; 1]; [1; 2]];
[[3; 2; 1]; [2; 3; 1]; [2; 1; 3]; [3; 1; 2]; [1; 3; 2]; [1; 2; 3]]]
980 is not the "defacto standard", you'll generally see most people targeting a size a little bit less than 1024px wide to account for browser chrome such as scrollbars, etc.
Usually people target between 960 and 990px wide. Often people use a grid system (like 960.gs) which is opinionated about what the default width should be.
Also note, just recently the most common screen size now averages quite a bit bigger than 1024px wide, ranking in at 1366px wide. See http://techcrunch.com/2012/04/11/move-over-1024x768-the-most-popular-screen-resolution-on-the-web-is-now-1366x768/
Using table aliases in the join condition:

Above methods will remove your output file data whenever you run above nohup command.
To Append output in user defined file you can use >>
in nohup command.
nohup your_command >> filename.out &
This command will append all output in your file without removing old data.
You need to use cat
to get the contents of the file named 'DSC_0251.JPG', rather than the filename itself.
test="$(cat DSC_0251.JPG | base64)"
However, base64
can read from the file itself:
test=$( base64 DSC_0251.JPG )
I'd extend the Array class with a pick_and_remove()
function, like so:
var ArrayInstanceExtensions = {
pick_and_remove: function(index){
var picked_element = this[index];
this.splice(index,1);
return picked_element;
}
};
$.extend(Array.prototype, ArrayInstanceExtensions);
While it may seem a bit verbose, you can now call pick_and_remove()
on any array you possibly want!
Usage:
array = [4,5,6] //=> [4,5,6]
array.pick_and_remove(1); //=> 5
array; //=> [4,6]
You can see all of this in pokemon-themed action here.
Something like this:

I compared the efficiency of the most popular suggestions to determine if a number is prime. I used python 3.6
on ubuntu 17.10
; I tested with numbers up to 100.000 (you can test with bigger numbers using my code below).
This first plot compares the functions (which are explained further down in my answer), showing that the last functions do not grow as fast as the first one when increasing the numbers.
And in the second plot we can see that in case of prime numbers the time grows steadily, but non-prime numbers do not grow so fast in time (because most of them can be eliminated early on).
Here are the functions I used:
this answer and this answer suggested a construct using all()
:
def is_prime_1(n):
return n > 1 and all(n % i for i in range(2, int(math.sqrt(n)) + 1))
This answer used some kind of while loop:
def is_prime_2(n):
if n <= 1:
return False
if n == 2:
return True
if n == 3:
return True
if n % 2 == 0:
return False
if n % 3 == 0:
return False
i = 5
w = 2
while i * i <= n:
if n % i == 0:
return False
i += w
w = 6 - w
return True
This answer included a version with a for
loop:
def is_prime_3(n):
if n <= 1:
return False
if n % 2 == 0 and n > 2:
return False
for i in range(3, int(math.sqrt(n)) + 1, 2):
if n % i == 0:
return False
return True
And I mixed a few ideas from the other answers into a new one:
def is_prime_4(n):
if n <= 1: # negative numbers, 0 or 1
return False
if n <= 3: # 2 and 3
return True
if n % 2 == 0 or n % 3 == 0:
return False
for i in range(5, int(math.sqrt(n)) + 1, 2):
if n % i == 0:
return False
return True

I know this is old and whatnot (and not exactly sure if it's a question), but after searching, I had success with this command for --onefile
:
pyinstaller.exe --onefile --windowed --icon=app.ico app.py
Google led me to this page while I was searching for an answer on how to set an icon for my .exe, so maybe it will help someone else.

Simple, single line of JavaScript code will give you the name of browser:
function GetBrowser()
{
return navigator ? navigator.userAgent.toLowerCase() : "other";
}
You can use a TextFormField
instead of TextField
, and use the initialValue
property. for example
TextFormField(initialValue: "I am smart")
In fact, most compilers emit the same code for both functions calls, because references are generally implemented using pointers.
Following this logic, when an argument of (non-const) reference type is used in the function body, the generated code will just silently operate on the address of the argument and it will dereference it. In addition, when a call to such a function is encountered, the compiler will generate code that passes the address of the arguments instead of copying their value.
Basically, references and pointers are not very different from an implementation point of view, the main (and very important) difference is in the philosophy: a reference is the object itself, just with a different name.
References have a couple more advantages compared to pointers (e. g. they can't be NULL
, so they are safer to use). Consequently, if you can use C++, then passing by reference is generally considered more elegant and it should be preferred. However, in C, there's no passing by reference, so if you want to write C code (or, horribile dictu, code that compiles with both a C and a C++ compiler, albeit that's not a good idea), you'll have to restrict yourself to using pointers.
Surely using array_map
and if using a container implementing ArrayAccess
to derive objects is just a smarter, semantic way to go about this?
Array map semantics are similar across most languages and implementations that I've seen. It's designed to return a modified array based upon input array element (high level ignoring language compile/runtime type preference); a loop is meant to perform more logic.
For retrieving objects by ID / PK, depending upon if you are using SQL or not (it seems suggested), I'd use a filter to ensure I get an array of valid PK's, then implode with comma and place into an SQL IN()
clause to return the result-set. It makes one call instead of several via SQL, optimising a bit of the call->wait
cycle. Most importantly my code would read well to someone from any language with a degree of competence and we don't run into mutability problems.
<?php
$arr = [0,1,2,3,4];
$arr2 = array_map(function($value) { return is_int($value) ? $value*2 : $value; }, $arr);
var_dump($arr);
var_dump($arr2);
vs
<?php
$arr = [0,1,2,3,4];
foreach($arr as $i => $item) {
$arr[$i] = is_int($item) ? $item * 2 : $item;
}
var_dump($arr);
If you know what you are doing will never have mutability problems (bearing in mind if you intend upon overwriting $arr
you could always $arr = array_map
and be explicit.
Just uninstall NPCAP and install wpcap. This will fix the issue.
For this html:
<div class="outer">
<div class="inner"></div>
</div>
This selector should work:
$('.outer > .inner')
The closest you will ever get to doing such thing is a dissasembler, or debug info (Log2Vis.pdb).
