This is my first post on SO, so I don't have enough reputation to comment the accepted answer, but I had to modify the code to the following:
export function focusNextElement () {
//add all elements we want to include in our selection
const focussableElements =
'a:not([disabled]), button:not([disabled]), input[type=text]:not([disabled])'
if (document.activeElement && document.activeElement.form) {
var focussable = Array.prototype.filter.call(
document.activeElement.form.querySelectorAll(focussableElements),
function (element) {
// if element has tabindex = -1, it is not focussable
if ( element.hasAttribute('tabindex') && element.tabIndex === -1 ){
return false
}
//check for visibility while always include the current activeElement
return (element.offsetWidth > 0 || element.offsetHeight > 0 ||
element === document.activeElement)
});
console.log(focussable)
var index = focussable.indexOf(document.activeElement);
if(index > -1) {
var nextElement = focussable[index + 1] || focussable[0];
console.log(nextElement)
nextElement.focus()
}
}
}
The changing of var to constant is non-critical. The main change is that we get rid of the selector that checks tabindex != "-1". Then later, if the element has the attribute tabindex AND it is set to "-1", we do NOT consider it focussable.
The reason I needed to change this was because when adding tabindex="-1" to an <input>
, this element was still considered focussable because it matches the "input[type=text]:not([disabled])" selector. My change is equivalent to "if we are a non-disabled text input, and we have a tabIndex attribute, and the value of that attribute is -1, then we should not be considered focussable.
I believe that when the author of the accepted answer edited their answer to account for the tabIndex attribute, they did not do so correctly. Please let me know if this is not the case

Hungry for spaghetti?
For me, the problem was twofold: First, the version of IIS I was dealing with didn't know about the .woff2
MIME type, only about .woff
. I fixed that using IIS Manager at the server level, not at the web app level, so the setting wouldn't get overridden with each new app deployment. (Under IIS Manager, I went to MIME types, and added the missing .woff2
, then updated .woff
.)
Second, and more importantly, I was bundling bootstrap.css
along with some other files as "~/bundles/css/site"
. Meanwhile, my font files were in "~/fonts"
. bootstrap.css
looks for the glyphicon fonts in "../fonts"
, which translated to "~/bundles/fonts"
-- wrong path.
In other words, my bundle path was one directory too deep. I renamed it to "~/bundles/siteCss"
, and updated all the references to it that I found in my project. Now bootstrap looked in "~/fonts"
for the glyphicon files, which worked. Problem solved.
Before I fixed the second problem above, none of the glyphicon
font files were loading. The symptom was that all instances of glyphicon
glyphs in the project just showed an empty box. However, this symptom only occurred in the deployed versions of the web app, not on my dev machine. I'm still not sure why that was the case.
How about the Omondo Plugin for Eclipse. I have used it and I find it to be quite useful. Although if you are generating diagrams for large sources, you might have to start Eclipse with more memory.
I manage to find the answer for this solution, have to do javascript injection for this to install atob
const atob:any = require('atob');
asn1(pem: any){
asn1parser.Enc.base64ToBuf = function (b64:any) {
return asn1parser.Enc.binToBuf(atob(b64));
};
const dertest = asn1parser.PEM.parseBlock(pem).der;
var hex = asn1parser.Enc.bufToHex(asn1parser.PEM.parseBlock(pem).der)
var buf = asn1parser.ASN1.parse(dertest);
var asn1 = JSON.stringify(asn1parser.ASN1.parse(dertest), asn1parser.ASN1._replacer, 2 );
Well In my parent directory I see:
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
Unmerged paths:
(use "git reset HEAD <file>..." to unstage)
(use "git add <file>..." to mark resolution)
So I just did this

It sounds like your PC hasn't contacted an authenticating domain controller for a little while. (I used to have this happen on my laptop a few times.)
It can also happen if your password expires.
You can achieve this using the location
object.
location.href = "http://someurl";
Yes You can compile and execute without main method By using static block. But after static block executed (printed) you will get an error saying no main method found.
And Latest INFO --> YOU cant Do this with JAVA 7 version. IT will not execute.
{
static
{
System.out.println("Hello World!");
System.exit(0); // prevents “main method not found” error
}
}
But this will not execute with JAVA 7 version.
I found this as an easiest way to add row . The awesome thing about this is that it doesn't change the already present table contents even if it contains input elements .
row = `<tr><td><input type="text"></td></tr>`
$("#table_body tr:last").after(row) ;
Here #table_body
is the id of the table body tag .
Try this:
UPDATE data_table t, (SELECT DISTINCT ID, NAME, VALUE
FROM data_table
WHERE VALUE IS NOT NULL AND VALUE != '') t1
SET t.VALUE = t1.VALUE
WHERE t.ID = t1.ID
AND t.NAME = t1.NAME
if you want to escape double quote in JSON use \\ to escape it.
example if you want to create json of following javascript object
{time: '7 "o" clock'}
then you must write in following way
'{"time":"7 \\"o\\" clock"}'
if we parse it using JSON.parse()
JSON.parse('{"time":"7 \\"o\\" clock"}')
result will be
{time: "7 "o" clock"}
I've searched for sleep solution too (not for production code, only for dev/tests) and found this article:

Also, when you are calling alert()
, your code will be paused too, while alert is shown -- need to find a way to not display alert but get the same effect. :)
Note: This answer is less current than it was when posted in 2009. Using the subprocess
module shown in other answers is now recommended in the docs
(Note that the subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using these functions.)
If you want your process to start in the background you can either use system()
and call it in the same way your shell script did, or you can spawn
it:
import os
os.spawnl(os.P_DETACH, 'some_long_running_command')
(or, alternatively, you may try the less portable os.P_NOWAIT
flag).
See the documentation here.
You basically need a helper method to read a stream into memory. This works pretty well:
public static byte[] readFully(InputStream stream) throws IOException
{
byte[] buffer = new byte[8192];
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int bytesRead;
while ((bytesRead = stream.read(buffer)) != -1)
{
baos.write(buffer, 0, bytesRead);
}
return baos.toByteArray();
}
Then you'd call it with:
public static byte[] loadFile(String sourcePath) throws IOException
{
InputStream inputStream = null;
try
{
inputStream = new FileInputStream(sourcePath);
return readFully(inputStream);
}
finally
{
if (inputStream != null)
{
inputStream.close();
}
}
}
Don't mix up text and binary data - it only leads to tears.
This is a late answer but I am putting it here for posterity
You can edit the svg and set its size. one of the reasons I like using svg's is because you can edit it in a text editor.
The following is a 32*32 svg which I internally resized to initially display as a 10*10 image. it worked perfectly to replace the list image
<?xml version="1.0" ?><svg width="10" height="10" id="chevron-right" viewBox="0 0 32 32" xmlns="http://www.w3.org/2000/svg"><path style="fill:#34a89b;" d="M12 1 L26 16 L12 31 L8 27 L18 16 L8 5 z"/></svg>
I then simply added the following to my css
* ul {
list-style: none;
list-style-image: url(../images/chevron-right.svg);
}
The list-style: none;
is important as it prevents the default list image from displaying while the alternate image is being loaded.
See this. Its also similar problem. Working i tried.
Dont remove dataType: 'JSON',
Note: echo only JSON Formate in PHP file if you use only php echo your ajax code return 200
Here is a more reliable version:
class D(object):
def __init__(self):
self.test = 20
self.test2 = 21
def __getattribute__(self, name):
if name == 'test':
return 0.
else:
return super(D, self).__getattribute__(name)
It calls __getattribute__ method from parent class, eventually falling back to object.__getattribute__ method if other ancestors don't override it.
In your config.ini
file of eclipse eclipse\configuration\config.ini
check this three things:

osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.0.v20080604.jar@1\:start
org.eclipse.equinox.simpleconfigurator.configUrl=file\:org.eclipse.equinox.simpleconfigurator\\bundles.info
And check whether these jars are in place or not, the jar files depend upon your version of eclipse .

validChars can be any construct, but I decided to select based on ascii code ranges removing control chars. In this example, it is a 12 character string.
string validChars = String.Join("", Enumerable.Range(33, (126 - 33)).Where(i => !(new int[] { 34, 38, 39, 44, 60, 62, 96 }).Contains(i)).Select(i => { return (char)i; }));
string.Join("", Enumerable.Range(1, 12).Select(i => { return validChars[(new Random(Guid.NewGuid().GetHashCode())).Next(0, validChars.Length - 1)]; }))
Assuming such a query would return a single row, you could use either
select @EmpId = Id from dbo.Employee
Or
set @EmpId = (select Id from dbo.Employee)
You could also use GenerationType.TABLE instead of IDENTITY which is only available after the insert.
As Pickle has some security concerns and is slow (source), I would go for JSON, as it is fast, built-in, human-readable, and interchangeable:
import json
data = {'another_dict': {'a': 0, 'b': 1}, 'a_list': [0, 1, 2, 3]}
# e.g. file = './data.json'
with open(file, 'w') as f:
json.dump(data, f)
Reading is similar easy:
with open(file, 'r') as f:
data = json.load(f)
This is similar to this answer, but implements the file handling correctly.
You cannot capture loopback on Solaris, HP-UX, or Windows, however you can very easily work around this limitation by using a tool like RawCap.
RawCap can capture raw packets on any ip including 127.0.0.1
(localhost/loopback). Rawcap can also generate a pcap
file. You can open and analyze the pcap
file with Wireshark.
See here for full details on how to monitor localhost using RawCap and Wireshark.
PreparedStatement
alone does not help you if you are still concatenating Strings.
For instance, one rogue attacker can still do the following:
Not only SQL, but even JPQL or HQL can be compromised if you are not using bind parameters.
Bottom line, you should never use string concatenation when building SQL statements. Use a dedicated API for that purpose, like JPA Criteria API.
This will keep the \n character, but you can also just wrap the quote in parentheses. Especially useful in RMarkdown.
t <- ("
this is a long
string
")
$('#apply-form input').blur(function()
{
if( !$(this).val() ) {
$(this).parents('p').addClass('warning');
}
});
And you don't necessarily need .length
or see if it's >0
since an empty string evaluates to false anyway but if you'd like to for readability purposes:
$('#apply-form input').blur(function()
{
if( $(this).val().length === 0 ) {
$(this).parents('p').addClass('warning');
}
});
If you're sure it will always operate on a textfield element then you can just use this.value
.
$('#apply-form input').blur(function()
{
if( !this.value ) {
$(this).parents('p').addClass('warning');
}
});
Also you should take note that $('input:text')
grabs multiple elements, specify a context or use the this
keyword if you just want a reference to a lone element (provided there's one textfield in the context's descendants/children).
My solution:
Object.prototype.__index = function(index)
{
var i = -1;
for (var key in this)
{
if (this.hasOwnProperty(key) && typeof(this[key])!=='function')
++i;
if (i >= index)
return this[key];
}
return null;
}
aObj = {'jack':3, 'peter':4, '5':'col', 'kk':function(){alert('hell');}, 'till':'ding'};
alert(aObj.__index(4));
Nirsoft's NirCMD can create shortcuts from a command line, too. (Along with a pile of other functions.) Free and available here:
http://www.nirsoft.net/utils/nircmd.html
Full instructions here: http://www.nirsoft.net/utils/nircmd2.html#using (Scroll down to the "shortcut" section.)
Yes, using nircmd does mean you are using another 3rd-party .exe, but it can do some functions not in (most of) the above solutions (e.g., pick a icon # in a dll with multiple icons, assign a hot-key, and set the shortcut target to be minimized or maximized).
Though it appears that the shortcutjs.bat solution above can do most of that, too, but you'll need to dig more to find how to properly assign those settings. Nircmd is probably simpler.
Have you installed it?

I ran into this problem with templated classes. Here's a more general solution I had to use:
template class <T>
class myClass
{
int myField;
// Helper function accessing my fields
void toString(std::ostream&) const;
// Friend means operator<< can use private variables
// It needs to be declared as a template, but T is taken
template <class U>
friend std::ostream& operator<<(std::ostream&, const myClass<U> &);
}
// Operator is a non-member and global, so it's not myClass<U>::operator<<()
// Because of how C++ implements templates the function must be
// fully declared in the header for the linker to resolve it :(
template <class U>
std::ostream& operator<<(std::ostream& os, const myClass<U> & obj)
{
obj.toString(os);
return os;
}
Now: * My toString() function can't be inline if it is going to be tucked away in cpp. * You're stuck with some code in the header, I couldn't get rid of it. * The operator will call the toString() method, it's not inlined.
The body of operator<< can be declared in the friend clause or outside the class. Both options are ugly. :(
Maybe I'm misunderstanding or missing something, but just forward-declaring the operator template doesn't link in gcc.
This works too:
template class <T>
class myClass
{
int myField;
// Helper function accessing my fields
void toString(std::ostream&) const;
// For some reason this requires using T, and not U as above
friend std::ostream& operator<<(std::ostream&, const myClass<T> &)
{
obj.toString(os);
return os;
}
}
I think you can also avoid the templating issues forcing declarations in headers, if you use a parent class that is not templated to implement operator<<, and use a virtual toString() method.
I want to answer this question by example. First of all Hibernate
project uses Reflection API
to generate CRUD
statements to bridge the chasm between the running application and the persistence store. When things change in the domain, the Hibernate
has to know about them to persist them to the data store and vice versa.
Alternatively works Lombok Project
. It just injects code at compile time, result in code being inserted into your domain classes. (I think it is OK for getters and setters)
Hibernate
chose reflection
because it has minimal impact on the build process for an application.
And from Java 7 we have MethodHandles
, which works as Reflection API
. In projects, to work with loggers we just copy-paste the next code:
Logger LOGGER = Logger.getLogger(MethodHandles.lookup().lookupClass().getName());
Because it is hard to make typo-error in this case.
If you have installed Azure CLI 2.0 in your machine, you should be able to get the list of subscription that you belong to with the following command,
az login
if you want to see as a table output you could just use
az account get-access-token --query tenant --output tsv
or you could use the Rest API
https://docs.microsoft.com/en-us/rest/api/resources/tenants/list
you can use :
public static void ReadFileToEnd()
{
try
{
//provide to reader your complete text file
using (StreamReader sr = new StreamReader("TestFile.txt"))
{
String line = sr.ReadToEnd();
Console.WriteLine(line);
}
}
catch (Exception e)
{
Console.WriteLine("The file could not be read:");
Console.WriteLine(e.Message);
}

+1 on S.Lott's suggestion of a named container class.
For Python 2.6 and up, a named tuple provides a useful way of easily creating these container classes, and the results are "lightweight and require no more memory than regular tuples".
I like putting the inputs inside the labels (added bonus: now you don't need the for
attribute on the label), and put vertical-align: middle
on the input.
label > input[type=radio] {_x000D_
vertical-align: middle;_x000D_
margin-top: -2px;_x000D_
}_x000D_
_x000D_
#d2 { _x000D_
font-size: 30px;_x000D_
}
_x000D_
<div>_x000D_
<label><input type="radio" name="radio" value="1">Good</label>_x000D_
<label><input type="radio" name="radio" value="2">Excellent</label>_x000D_
<div>_x000D_
<br>_x000D_
<div id="d2">_x000D_
<label><input type="radio" name="radio2" value="1">Good</label>_x000D_
<label><input type="radio" name="radio2" value="2">Excellent</label>_x000D_
<div>
_x000D_
(The -2px margin-top
is a matter of taste.)
Another option I really like is using a table. (Hold your pitch forks! It's really nice!) It does mean you need to add the for
attribute to all your labels and id
s to your inputs. I'd recommended this option for labels with long text content, over multiple lines.
<table><tr><td>_x000D_
<input id="radioOption" name="radioOption" type="radio" />_x000D_
</td><td>_x000D_
<label for="radioOption"> _x000D_
Really good option_x000D_
</label>_x000D_
</td></tr></table>
_x000D_

I just found out, that by using asset_url
helper you solve that problem.
asset_url("backgrounds/pattern.png", image)
I had the same problem and finally resolved it by changing the order of pem blocks in certificate file.
The cert block should be put in the beginning of the file, then intermediate blocks, then root block.
I realized this problem by comparing a problematic certificate file with a working certificate file.
You should in fact URI-encode the "invalid" characters. Since the string actually contains the complete URL, it's hard to properly URI-encode it. You don't know which slashes /
should be taken into account and which not. You cannot predict that on a raw String
beforehand. The problem really needs to be solved at a higher level. Where does that String
come from? Is it hardcoded? Then just change it yourself accordingly. Does it come in as user input? Validate it and show error, let the user solve itself.
At any way, if you can ensure that it are only the spaces in URLs which makes it invalid, then you can also just do a string-by-string replace with %20
:
URI uri = new URI(string.replace(" ", "%20"));
Or if you can ensure that it's only the part after the last slash which needs to be URI-encoded, then you can also just do so with help of android.net.Uri
utility class:
int pos = string.lastIndexOf('/') + 1;
URI uri = new URI(string.substring(0, pos) + Uri.encode(string.substring(pos)));
Do note that URLEncoder
is insuitable for the task as it's designed to encode query string parameter names/values as per application/x-www-form-urlencoded
rules (as used in HTML forms). See also Java URL encoding of query string parameters.
FYI, I found I needed to put matplotlib.use('Agg')
first in Python import order. For what I was doing (unit testing needed to be headless) that meant putting
import matplotlib
matplotlib.use('Agg')
at the top of my master test script. I didn't have to touch any other files.
In C# 6 you can use string interpolation:
string name = "John";
string result = $"Hello {name}";
The syntax highlighting for this in Visual Studio makes it highly readable and all of the tokens are checked.
I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser
which is doing most of the work. Where he puts req.body.name
, I believe he/she is using body-parser
to get the contents of the name attribute(s) received when the form is submitted.
If you do not want to use Express, use querystring
which is a built-in Node module. See the answers in the link below for an example of how to use querystring
.
It might help to look at this answer, which is very similar to your quest.
With Exceptions, I try the following:
First, I catch special types of exceptions like division by zero, IO operations, and so on and write code according to that. For example, a division by zero, depending the provenience of the values I could alert the user (example a simple calculator in that in a middle calculation (not the arguments) arrives in a division by zero) or to silently treat that exception, logging it and continue processing.
Then I try to catch the remaining exceptions and log them. If possible allow the execution of code, otherwise alert the user that a error happened and ask them to mail a error report.
In code, something like this:
try{
//Some code here
}
catch(DivideByZeroException dz){
AlerUserDivideByZerohappened();
}
catch(Exception e){
treatGeneralException(e);
}
finally{
//if a IO operation here i close the hanging handlers for example
}
it could be also you are trying to index in the wrong way:
a = 'apple'
a(3) ===> 'str' object is not callable
a[3] = l
To know the react version, Open package.json file in root folder, search the keywork react. You will see like "react": "^16.4.0",
Java will not throw an exception if you divide by float zero. It will detect a run-time error only if you divide by integer zero not double zero.
If you divide by 0.0, the result will be INFINITY.
The only solution that worked for me and $.each
was definitely causing the error. so i used for loop
and it's not throwing error anymore.
Example code
$.ajax({
type: 'GET',
url: 'https://example.com/api',
data: { get_param: 'value' },
success: function (data) {
for (var i = 0; i < data.length; ++i) {
console.log(data[i].NameGerman);
}
}
});
Look this:
List<Client> result = clients
.stream()
.filter(c ->
(users.stream().map(User::getName).collect(Collectors.toList())).contains(c.getName()))
.collect(Collectors.toList());
Exits the loop if the line is empty(Improving code).

You can loop through the DataColumn and DataRow collections in your DataTable:
// Sum rows.
foreach (DataRow row in dt.Rows) {
int rowTotal = 0;
foreach (DataColumn col in row.Table.Columns) {
Console.WriteLine(row[col]);
rowTotal += Int32.Parse(row[col].ToString());
}
Console.WriteLine("row total: {0}", rowTotal);
}
// Sum columns.
foreach (DataColumn col in dt.Columns) {
int colTotal = 0;
foreach (DataRow row in col.Table.Rows) {
Console.WriteLine(row[col]);
colTotal += Int32.Parse(row[col].ToString());
}
Console.WriteLine("column total: {0}", colTotal);
}
Beware: The code above does not do any sort of checking before casting an object to an int.
EDIT: add a DataRow displaying the column sums
Try this to create a new row to display your column sums:
DataRow totalsRow = dt.NewRow();
foreach (DataColumn col in dt.Columns) {
int colTotal = 0;
foreach (DataRow row in col.Table.Rows) {
colTotal += Int32.Parse(row[col].ToString());
}
totalsRow[col.ColumnName] = colTotal;
}
dt.Rows.Add(totalsRow);
This approach is fine if the data type of any of your DataTable's DataRows are non-numeric or if you want to inspect the value of each cell as you sum. Otherwise I believe @Tim's response using DataTable.Compute
is a better.
The reason of this warning is i was presenting a view controller over a small view that is not full size view. Given below is the image of my project. where on click on four option above. User navigate to different childviewcontroller's view.(it works like tabViewcontroller). But the childviewcontroller contains view of small size. So if we present a view from childviewcontroller it gives this warning.
And to avoid this, you can present a view on childviewcontroller's parent
[self.parentViewController presentViewController:viewController animated:YES completion:nil];
You need to call the AddAddress
method once for every recipient. Like so:
$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..
Better yet, add them as Carbon Copy recipients.
$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..
To make things easy, you should loop through an array to do this.
$recipients = array(
'[email protected]' => 'Person One',
'[email protected]' => 'Person Two',
// ..
);
foreach($recipients as $email => $name)
{
$mail->AddCC($email, $name);
}
Use StreamReader
and direct it to detect the encoding for you:
using (var reader = new System.IO.StreamReader(path, true))
{
var currentEncoding = reader.CurrentEncoding;
}
And use Code Page Identifiers https://msdn.microsoft.com/en-us/library/windows/desktop/dd317756(v=vs.85).aspx in order to switch logic depending on it.
If you have several heroku apps, you must type heroku restart --app app_name
or heroku restart -a app_name
You need to call the
$.parseJSON();
For example:
...
success: function(data){
var json = $.parseJSON(data); // create an object with the key of the array
alert(json.html); // where html is the key of array that you want, $response['html'] = "<a>something..</a>";
},
error: function(data){
var json = $.parseJSON(data);
alert(json.error);
} ...
see this in http://api.jquery.com/jQuery.parseJSON/
if you still have the problem of slashes: search for security.magicquotes.disabling.php or: function.stripslashes.php
Note:
This answer here is for those who try to use $.ajax
with the dataType
property set to json
and even that got the wrong response type. Defining the header('Content-type: application/json');
in the server may correct the problem, but if you are returning text/html
or any other type, the $.ajax
method should convert it to json
. I make a test with older versions of jQuery and only after version 1.4.4
the $.ajax
force to convert any content-type to the dataType
passed. So if you have this problem, try to update your jQuery version.
If object is in some namespace ie. Company.Module.Components.Foo
you can use this function:
CoffeeScript:
objByName: (name, context = window) ->
ns = name.split "."
func = context
for n, i in ns
func = func[n]
return func
Resulted Js:
objByName: function(name, context) {
var func, i, n, ns, _i, _len;
if (context == null) {
context = window;
}
ns = name.split(".");
func = context;
for (i = _i = 0, _len = ns.length; _i < _len; i = ++_i) {
n = ns[i];
func = func[n];
}
return func;
}
Then you can create a new object or do whatever. Note the parenthises through.
var o = new (objByName('Company.Module.Components.Foo'))
objByName('some.deeply.nested.object').value
This idea is borrowed from similar question: How to execute a JavaScript function when I have its name as a string
Go to menu File → Preferences → User Settings.
It will open up Default Settings and settings.json
automatically. Just add the following in the settings.json
file and save it. This will overwrite the default settings.
// Place your settings in this file to overwrite the default settings
{ "editor.wrappingColumn": 0 }
def aliasAllColumns(t: DataFrame, p: String = "", s: String = ""): DataFrame =
{
t.select( t.columns.map { c => t.col(c).as( p + c + s) } : _* )
}
In case is isn't obvious, this adds a prefix and a suffix to each of the current column names. This can be useful when you have two tables with one or more columns having the same name, and you wish to join them but still be able to disambiguate the columns in the resultant table. It sure would be nice if there were a similar way to do this in "normal" SQL.
Create the war file in a different directory to where the content is otherwise the jar command might try to zip up the file it is creating.
#!/bin/bash
set -euo pipefail
war=app.war
src=contents
# Clean last war build
if [ -e ${war} ]; then
echo "Removing old war ${war}"
rm -rf ${war}
fi
# Build war
if [ -d ${src} ]; then
echo "Found source at ${src}"
cd ${src}
jar -cvf ../${war} *
cd ..
fi
# Show war details
ls -la ${war}
To limit the zoom on v.3+. in your map setting add default zoom level and minZoom or maxZoom (or both if required) zoom levels are 0 to 19. You must declare deafult zoom level if limitation is required. all are case sensitive!
function initialize() {
var mapOptions = {
maxZoom:17,
minZoom:15,
zoom:15,
....
Your code should read -
String kk = wd.findElement(By.cssSelector("div[id^='customSelect'] span.selectLabel")).getText();
Use CSS. it's much cleaner and easier.. Let me know if that solves your issue.
Recreating an AVD with the Hardware Keyboard + setting the boolean to true was the only solution that worked for me; the other two main solutions (terminal or editing an existing AVD via GUI) both resulted in software/emulator crashes on my Mac. Making a new AVD resulted in the keyboard working just fine.
You can try:
function onlyAlphabets(e, t) {
return (e.charCode > 64 && e.charCode < 91) || (e.charCode > 96 && e.charCode < 123) || e.charCode == 32;
}
Curl does that by default without any parameters or flags, I would use it for your purposes:
curl $url > /dev/null 2>&1
Curl is more about streams and wget is more about copying sites based on this comparison.
None of the above solution work for me. I tried and very frustrated until I watched the following video: https://www.youtube.com/watch?v=tGinfzlp0fE
pip uninstall mysql-connector
work on some computer and it might not work for other computer.
I did the followings:
pip uninstall mysql-connector
pip uninstall mysql-connector-python
pip install mysql-connector-python
I've modified kernel on Nexus 7 to act like standard HID keyboard and mouse, without losing MTP/ADB/other USB functionality.
You can use usb-gadget-test commandline utility to send keystrokes and mouse movements to your PC. I want to create a remote admin app later, which will send key events and receive video from camera.
Kernel patch, binaries and instructions: https://github.com/pelya/android-keyboard-gadget
Edit: I've published a proper app to Google Play, if your Nexus 7 is rooted you can flash kernel right from the app, and send keypresses with it.
My two cents here:
myvariable=$(mysql database -u $user -p$password -sse "SELECT A, B, C FROM table_a" 2>&1 \
| grep -v "Using a password")
Removes both the column names and the annoying (but necessary) password warning. Thanks @Dominic Bartl and John for this answer.
Klocwork has a static analysis tool for C#: http://www.klocwork.com
There are multiple ways
return \Response::json(['hello' => $value], STATUS_CODE);
return response()->json(['hello' => $value], STATUS_CODE);
where STATUS_CODE is your HTTP status code you want to send. Both are identical.
if you are using Eloquent model, then simple return will also be auto converted in JSON by default like,
return User::all();
I had this problem too, somehow my code did not present the exact values but rounded the number in seconds to 0.0 (if milliseconds was under 1 second). What helped me out is adding the decimal to the division value.
double time_seconds = time_milliseconds / 1000.0; // add the decimal
System.out.println(time_milliseconds); // Now this should give you the right value.
The posted solutions will not link any hidden files. To include them, try this:
cd /usr/lib
find /mnt/usr/lib -maxdepth 1 -print "%P\n" | while read file; do ln -s "/mnt/usr/lib/$file" "$file"; done
If you should happen to want to recursively create the directories and only link files (so that if you create a file within a directory, it really is in /usr/lib
not /mnt/usr/lib
), you could do this:
cd /usr/lib
find /mnt/usr/lib -mindepth 1 -depth -type d -printf "%P\n" | while read dir; do mkdir -p "$dir"; done
find /mnt/usr/lib -type f -printf "%P\n" | while read file; do ln -s "/mnt/usr/lib/$file" "$file"; done
Expanding slightly on @Assaf answer, to apply formatting correctly I also had to convert the DateTime
via the .ToOADate()
function before the formatting took effect. You can do this on a cell by cell basis:
xlWorkSheet.Cells[Row, Col].NumberFormat = "<Required Format>"; // e.g. dd-MMM-yyyy
xlWorkSheet.Cells[Row, Col] = DateTimeObject.ToOADate();
Or you can apply the formatting to the entire column:
xlWorkSheet.Cells[Row, Col].EntireColumn.NumberFormat = "<Required Format>"; // e.g. dd-MMM-yyyy
xlWorkSheet.Cells[Row, Col] = DateTimeObject.ToOADate();
request has been deprecated as of February 2020, I'll leave the answer below for historical reasons, but please consider moving to an alternative listed in this issue.
I did something similar but I used request instead:
var request = require('request');
app.get('/', function(req,res) {
//modify the url in any way you want
var newurl = 'http://google.com/';
request(newurl).pipe(res);
});
I hope this helps, took me a while to realize that I could do this :)
After compiling a few answers, I've come up with the following code. What surprised me was that the timer does not get frozen on a PC (Chrome, FF) or Android Chrome - the trigger worked in the background, and the visibility check was the only reliable info.
var timestamp = new Date().getTime();
var timerDelay = 5000;
var processingBuffer = 2000;
var redirect = function(url) {
//window.location = url;
log('ts: ' + timestamp + '; redirecting to: ' + url);
}
var isPageHidden = function() {
var browserSpecificProps = {hidden:1, mozHidden:1, msHidden:1, webkitHidden:1};
for (var p in browserSpecificProps) {
if(typeof document[p] !== "undefined"){
return document[p];
}
}
return false; // actually inconclusive, assuming not
}
var elapsedMoreTimeThanTimerSet = function(){
var elapsed = new Date().getTime() - timestamp;
log('elapsed: ' + elapsed);
return timerDelay + processingBuffer < elapsed;
}
var redirectToFallbackIfBrowserStillActive = function() {
var elapsedMore = elapsedMoreTimeThanTimerSet();
log('hidden:' + isPageHidden() +'; time: '+ elapsedMore);
if (isPageHidden() || elapsedMore) {
log('not redirecting');
}else{
redirect('appStoreUrl');
}
}
var log = function(msg){
document.getElementById('log').innerHTML += msg + "<br>";
}
setTimeout(redirectToFallbackIfBrowserStillActive, timerDelay);
redirect('nativeApp://');
The problem is that you're trying start the animation too early in the view controller's lifecycle. In viewDidLoad
, the view has just been created, and hasn't yet been added to the view hierarchy, so attempting to animate one of its subviews
at this point produces bad results.
What you really should be doing is continuing to set the alpha of the view in viewDidLoad
(or where you create your views), and then waiting for the viewDidAppear
: method to be called. At this point, you can start your animations without any issue.
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
UIView.animate(withDuration: 1.5) {
self.myFirstLabel.alpha = 1.0
self.myFirstButton.alpha = 1.0
self.mySecondButton.alpha = 1.0
}
}
Have you checked this http://support.microsoft.com/kb/209805? In particular, whether you have Msrd3x40.dll.

You entered an alphanumeric and int, blank delimited in mystr
.
You then tried to convert the first token (blank delimited) into an int
.
The first token was RS which failed to convert to int
, leaving a zero for myprice, and we all know what zero times anything yields.
When you only entered int values the second time, everything worked as you expected.
It was the spurious RS that caused your code to fail.
You should give an object as argument
userModel.count({name: "sam"});
or
userModel.count({name: "sam"}).exec(); //if you are using promise
or
userModel.count({}); // if you want to get all counts irrespective of the fields
On the recent version of mongoose, count() is deprecated so use
userModel.countDocuments({name: "sam"});
For a Linux installation make sure you use sudo. Also it's good to look for images that are months and weeks old:
sudo docker ps -a | grep 'weeks ago\|months ago' | \
awk '{print $1}' | xargs --no-run-if-empty sudo docker rm
The JOIN syntax keeps conditions near the table they apply to. This is especially useful when you join a large amount of tables.
By the way, you can do an outer join with the first syntax too:
WHERE a.x = b.x(+)
Or
WHERE a.x *= b.x
Or
WHERE a.x = b.x or a.x not in (select x from b)

We can break both a $(selector).each()
loop and a $.each()
loop at a particular iteration by making the callback function return false
. Returning non-false
is the same as a continue statement in a for
loop; it will skip immediately to the next iteration.
return false; // this is equivalent of 'break' for jQuery loop
return; // this is equivalent of 'continue' for jQuery loop
Note that $(selector).each()
and $.each()
are different functions.

Or, if you want to send the custom header for every future request, then you could use the following:
$.ajaxSetup({
headers: { "CustomHeader": "myValue" }
});
This way every future ajax request will contain the custom header, unless explicitly overridden by the options of the request. You can find more info on ajaxSetup

Based on (dangerouslySetInnerHTML).
It's a prop that does exactly what you want. However they name it to convey that it should be use with caution
Solution
You can use the troubleshooting tips below.
Troubleshooting Tip #1
Exit Eclipse
Open a web browser and visit, http://localhost:8080
If you see a "Tomcat" web page then that means Tomcat is running as a Windows service. To stop Tomcat running as a Windows services, open your Windows Control Panel. Find the service "Apache Tomcat" and stop it.
If you don't see a "Tomcat" web page, then stop the appropriate process displayed.
-- Troubleshooting Tip #2 - GUI Option
Steps to free port which is already used to run Tomcat server in Eclipse
On MS Windows, select Start > All Programs > Accessories > System Tools >Resource Monitor
Expand the Network Tab
Move to the section for Listening Ports
Look in the Port column and scroll to find entry for port 8080
Select the given process and delete/kill the process
Return back to Eclipse and start the Tomcat Server, it should start up now.
Troubleshooting Tip #3 - Command-Line Option
Steps to free port which is already used to run Tomcat server in Eclipse
For example , suppose 8080 port is used , we need to make free 8080 to run tomcat
Step 1: (open the CMD command)
C:\Users\username>netstat -o -n -a | findstr 0.0:8080
TCP 0.0.0.0:3000 0.0.0.0:0 LISTENING 3116
Now , we can see that LISTENING port is 3116 for 8080 ,
We need to kill 3116 now
Step 2:
C:\Users\username>taskkill /F /PID 3116
Step 3: Return back to Eclipse and start the Tomcat Server, it should start up now.
====
Mac/Linux SOLUTION
Step 0: Exit Eclipse
Step 1: Open a terminal window
Step 2: Enter the following command to find the process id
lsof -i :8080 This will give output of the application that is running on port 8080
Step 3: Enter the following command to kill the process
kill $(lsof -t -i :8080)
Step 4: Return back to Eclipse and start the Tomcat Server, it should start up now.
Cross join :Cross Joins produce results that consist of every combination of rows from two or more tables. That means if table A has 3 rows and table B has 2 rows, a CROSS JOIN will result in 6 rows. There is no relationship established between the two tables – you literally just produce every possible combination.
Full outer Join : A FULL OUTER JOIN is neither "left" nor "right"— it's both! It includes all the rows from both of the tables or result sets participating in the JOIN. When no matching rows exist for rows on the "left" side of the JOIN, you see Null values from the result set on the "right." Conversely, when no matching rows exist for rows on the "right" side of the JOIN, you see Null values from the result set on the "left."
You can use Postgres' SIMILAR TO
operator which supports alternations, i.e.
select * from table where lower(value) similar to '%(foo|bar|baz)%';
The quick and dirty method is as follows:
cat ip_addresses | sort -n | uniq -c
If you need to use the values in bash you can assign the whole command to a bash variable and then loop through the results.
PS
If the sort command is omitted, you will not get the correct results as uniq only looks at successive identical lines.
I think there's a simpler solution: Just use the DialogInterface
argument that is passed to the onClick
method.
AlertDialog.Builder db = new AlertDialog.Builder(context);
db.setNegativeButton("cancel", new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface d, int arg1) {
db.cancel();
//here db.cancel will dismiss the builder
};
});
See, for example, http://www.mkyong.com/android/android-alert-dialog-example.
Just to clarify the problem here - the error is in the following bit of code:
<xsl:attribute name="src">
<xsl:copy-of select="/root/Image/node()"/>
</xsl:attribute>
The instruction xsl:copy-of takes a node or node-set and makes a copy of it - outputting a node or node-set. However an attribute cannot contain a node, only a textual value, so xsl:value-of would be a possible solution (as this returns the textual value of a node or nodeset).
A MUCH shorter solution (and perhaps more elegant) would be the following:
<img width="100" height="100" src="{/root/Image/node()}" class="CalloutRightPhoto"/>
The use of the {} in the attribute is called an Attribute Value Template, and can contain any XPATH expression.
Note, the same XPath can be used here as you have used in the xsl_copy-of as it knows to take the textual value when used in a Attribute Value Template.
I faced the same issue recently, but i was not able to get answer in google. So thought of sharing it here, so that it can help someone in future.

on a SELECT DISTINCT
statement, the ROW_NUMBER()
will produce distinct values before they are removed by the DISTINCT
keyword. E.g. this query
SELECT DISTINCT
v,
ROW_NUMBER() OVER (ORDER BY v) row_number
FROM t
ORDER BY v, row_number
... might produce this result (DISTINCT
has no effect):
+---+------------+
| V | ROW_NUMBER |
+---+------------+
| a | 1 |
| a | 2 |
| a | 3 |
| b | 4 |
| c | 5 |
| c | 6 |
| d | 7 |
| e | 8 |
+---+------------+
Whereas this query:
SELECT DISTINCT
v,
DENSE_RANK() OVER (ORDER BY v) row_number
FROM t
ORDER BY v, row_number
... produces what you probably want in this case:
+---+------------+
| V | ROW_NUMBER |
+---+------------+
| a | 1 |
| b | 2 |
| c | 3 |
| d | 4 |
| e | 5 |
+---+------------+
Note that the ORDER BY
clause of the DENSE_RANK()
function will need all other columns from the SELECT DISTINCT
clause to work properly.
Using PostgreSQL / Sybase / SQL standard syntax (WINDOW
clause):
SELECT
v,
ROW_NUMBER() OVER (window) row_number,
RANK() OVER (window) rank,
DENSE_RANK() OVER (window) dense_rank
FROM t
WINDOW window AS (ORDER BY v)
ORDER BY v
... you'll get:
+---+------------+------+------------+
| V | ROW_NUMBER | RANK | DENSE_RANK |
+---+------------+------+------------+
| a | 1 | 1 | 1 |
| a | 2 | 1 | 1 |
| a | 3 | 1 | 1 |
| b | 4 | 4 | 2 |
| c | 5 | 5 | 3 |
| c | 6 | 5 | 3 |
| d | 7 | 7 | 4 |
| e | 8 | 8 | 5 |
+---+------------+------+------------+
You want reorder()
. Here is an example with dummy data
set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))
require("ggplot2")
p1 <- ggplot(df, aes(x = Category, y = Count)) +
geom_bar(stat = "identity")
p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
geom_bar(stat = "identity")
require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))
Giving:
Use reorder(Category, Count)
to have Category
ordered from low-high.
If you have a pd.Series
object x
with index named 'Gene', you can use reset_index
and supply the name
argument:
df = x.reset_index(name='count')
Here's a demo:
x = pd.Series([2, 7, 1], index=['Ezh2', 'Hmgb', 'Irf1'])
x.index.name = 'Gene'
df = x.reset_index(name='count')
print(df)
Gene count
0 Ezh2 2
1 Hmgb 7
2 Irf1 1

An Alternative to AsyncTask is robospice. https://github.com/octo-online/robospice.
Some of the features of robospice.
1.executes asynchronously (in a background AndroidService) network requests (ex: REST requests using Spring Android).notify you app, on the UI thread, when result is ready.
2.is strongly typed ! You make your requests using POJOs and you get POJOs as request results.
3.enforce no constraints neither on POJOs used for requests nor on Activity classes you use in your projects.
4.caches results (in Json with both Jackson and Gson, or Xml, or flat text files, or binary files, even using ORM Lite).
5.notifies your activities (or any other context) of the result of the network request if and only if they are still alive
6.no memory leak at all, like Android Loaders, unlike Android AsyncTasks notifies your activities on their UI Thread.
7.uses a simple but robust exception handling model.
Samples to start with. https://github.com/octo-online/RoboSpice-samples.
A sample of robospice at https://play.google.com/store/apps/details?id=com.octo.android.robospice.motivations&feature=search_result.
Starting with the code from the other question:
class MyClass {
private static MyClass myClass = new MyClass();
private static final Object obj = new Object();
public MyClass() {
System.out.println(obj); // will print null once
}
}
A reference to this class will start initialization. First, the class will be marked as initialized. Then the first static field will be initialized with a new instance of MyClass(). Note that myClass is immediately given a reference to a blank MyClass instance. The space is there, but all values are null. The constructor is now executed and prints obj
, which is null.
Now back to initializing the class: obj
is made a reference to a new real object, and we're done.
If this was set off by a statement like: MyClass mc = new MyClass();
space for a new MyClass instance is again allocated (and the reference placed in mc
). The constructor is again executed and again prints obj
, which now is not null.
The real trick here is that when you use new
, as in WhatEverItIs weii = new WhatEverItIs( p1, p2 );
weii
is immediately given a reference to a bit of nulled memory. The JVM will then go on to initialize values and run the constructor. But if you somehow reference weii
before it does so--by referencing it from another thread or or by referencing from the class initialization, for instance--you are looking at a class instance filled with null values.
I'm glad that worked out, so I guess you had to explicitly set 'auto' on IE6 in order for it to mimic other browsers!
I actually recently found another technique for scaling images, again designed for backgrounds. This technique has some interesting features:
The markup relies on a wrapper element:
<div id="wrap"><img src="test.png" /></div>
Given the above markup you then use these rules:
#wrap {
height: 100px;
width: 100px;
}
#wrap img {
min-height: 100%;
min-width: 100%;
}
If you then control the size of wrapper you get the interesting scale effects that I list above.
To be explicit, consider the following base state: A container that is 100x100 and an image that is 10x10. The result is a scaled image of 100x100.
So, in other words, the image is always at least as big as the container, but will scale beyond it to maintain it's aspect ratio.
This probably isn't useful for your site, and it doesn't work in IE6. But, it is useful to get a scaled background for your view port or container.
I try my darned best to write exception-safe code, yes.
That means I take care to keep an eye on which lines can throw. Not everyone can, and it is critically important to keep that in mind. The key is really to think about, and design your code to satisfy, the exception guarantees defined in the standard.
Can this operation be written to provide the strong exception guarantee? Do I have to settle for the basic one? Which lines may throw exceptions, and how can I ensure that if they do, they don't corrupt the object?
append
: Appends object at the end.
x = [1, 2, 3]
x.append([4, 5])
print (x)
gives you: [1, 2, 3, [4, 5]]
extend
: Extends list by appending elements from the iterable.
x = [1, 2, 3]
x.extend([4, 5])
print (x)
gives you: [1, 2, 3, 4, 5]
for (char letter = 'a'; letter <= 'z'; letter++)
{
System.out.println(letter);
}
Use this:
from c in dc.Organization
where SqlMethods.Like(c.Hierarchy, "%/12/%")
select *;
We use SFTP with SSH (on both our development and live servers), and I have tried (not too hard though) to use the WordPress upload feature. I agree with Toby, upload your plugin(s) to the wp-content/plugins
directory and then activate them from there.
Try setting maxReceivedMessageSize on the server too, e.g. to 4MB:
<binding name="MyService.MyServiceBinding"
maxReceivedMessageSize="4194304">
The main reason the default (65535 I believe) is so low is to reduce the risk of Denial of Service (DoS) attacks. You need to set it bigger than the maximum request size on the server, and the maximum response size on the client. If you're in an Intranet environment, the risk of DoS attacks is probably low, so it's probably safe to use a value much higher than you expect to need.
By the way a couple of tips for troubleshooting problems connecting to WCF services:
Enable tracing on the server as described in this MSDN article.
Use an HTTP debugging tool such as Fiddler on the client to inspect the HTTP traffic.
To my knowledge, Ejabberd (http://www.ejabberd.im/) is the parent, this is XMPP server which provide quite good features of open source, Whatsapp uses some modified version of this, facebook messaging also uses a modified version of this. Some more chat applications likes Samsung's ChatOn, Nimbuzz messenger all use ejabberd based ones and Erlang solutions also have modified version of this ejabberd which they claim to be highly scalable and well tested with more performance improvements and renamed as MongooseIM.
Ejabberd is the server which has most of the featured implemented when compared to other. Since it is build in Erlang it is highly scalable horizontally.

If you're looking for reflection of all properties, the answers above are great.
If you're simply looking to get the keys of a dictionary (which is different from an 'object' in Python), use
my_dict.keys()
my_dict = {'abc': {}, 'def': 12, 'ghi': 'string' }
my_dict.keys()
> ['abc', 'def', 'ghi']
Do you really need to do that programmatically?
Just considering the title: You could use a ShapeDrawable as android:background…
For example, let's define res/drawable/my_custom_background.xml
as:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="2dp"
android:topRightRadius="0dp"
android:bottomRightRadius="0dp"
android:bottomLeftRadius="0dp" />
<stroke
android:width="1dp"
android:color="@android:color/white" />
</shape>
and define android:background="@drawable/my_custom_background".
I've not tested but it should work.
Update:
I think that's better to leverage the xml shape drawable resource power if that fits your needs. With a "from scratch" project (for android-8), define res/layout/main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/border"
android:padding="10dip" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello World, SOnich"
/>
[... more TextView ...]
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello World, SOnich"
/>
</LinearLayout>
and a res/drawable/border.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="5dip"
android:color="@android:color/white" />
</shape>
Reported to work on a gingerbread device. Note that you'll need to relate android:padding
of the LinearLayout to the android:width
shape/stroke's value. Please, do not use @android:color/white
in your final application but rather a project defined color.
You could apply android:background="@drawable/border" android:padding="10dip"
to each of the LinearLayout from your provided sample.
As for your other posts related to display some circles as LinearLayout's background, I'm playing with Inset/Scale/Layer drawable resources (see Drawable Resources for further information) to get something working to display perfect circles in the background of a LinearLayout but failed at the moment…
Your problem resides clearly in the use of getBorder.set{Width,Height}(100);
. Why do you do that in an onClick method?
I need further information to not miss the point: why do you do that programmatically? Do you need a dynamic behavior? Your input drawables are png or ShapeDrawable is acceptable? etc.
To be continued (maybe tomorrow and as soon as you provide more precisions on what you want to achieve)…
select Name, Value, AnotherColumn
from out_pumptable
where Value =
(
select Max(Value)
from out_pumptable as f where f.Name=out_pumptable.Name
)
group by Name, Value, AnotherColumn
Try like this, It works.
New to the python world!
I need a System Time independent Stopwatch so I did translate my old C++ class into Python:
from ctypes.wintypes import DWORD
import win32api
import datetime
class Stopwatch:
def __init__(self):
self.Restart()
def Restart(self):
self.__ulStartTicks = DWORD(win32api.GetTickCount()).value
def ElapsedMilliSecs(self):
return DWORD(DWORD(win32api.GetTickCount()).value-DWORD(self.__ulStartTicks).value).value
def ElapsedTime(self):
return datetime.timedelta(milliseconds=self.ElapsedMilliSecs())
This has no 49 days run over issue due to DWORD math but NOTICE that GetTickCount
has about 15 milliseconds granularity so do not use this class if your need 1-100 milliseconds elapsed time ranges.
Any improvement or feedback is welcome!
string [] temp = new string[] {"1","2","3"};
List<string> temp2 = temp.ToList();
I based this additional function on Nick Stinemates
def add_node_at_end(self, data):
new_node = Node()
node = self.curr_node
while node:
if node.next == None:
node.next = new_node
new_node.next = None
new_node.data = data
node = node.next
The method he has adds the new node at the beginning while I have seen a lot of implementations which usually add a new node at the end but whatever, it is fun to do.
Provide a module whose responsibility is to execute requests sequentially, while tracking the current index of each operation in an ordinal manner. Define the operation in a Command Pattern for flexibility.
execute
method to chain & track each operation. SequentialPromise returns a Promise-Chain from all operations performed.execute
method while passing in an ordinal list of options for each operation.Use SequentialPromise when ordinal behavior of Promise resolution is needed. SequentialPromise will track the index for which a Promise was rejected.

Just to add that from SQL Server 2008, there is a TIME datatype so from then on you can do:
SELECT CONVERT(TIME, GETDATE())
Might be useful for those that use SQL 2008+ and find this question.

I faced the same issue:
E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation
I resolved by using the following commands:
apt-get update
apt-get install gnupg
To add one day to a date object:
var date = new Date();
// add a day
date.setDate(date.getDate() + 1);
You can use this too:
<?php
$youtube_view_count = json_decode(file_get_contents('http://gdata.youtube.com/feeds/api/videos/wGG543FeHOE?v=2&alt=json'))->entry->{'yt$statistics'}->viewCount;
echo $youtube_view_count;
?>
Ultimately, I want to be able to echo out a signle field like so:
$row['option_value']
So why don't you? It should work.
Yep, using the staticmethod decorator
class MyClass(object):
@staticmethod
def the_static_method(x):
print(x)
MyClass.the_static_method(2) # outputs 2
Note that some code might use the old method of defining a static method, using staticmethod
as a function rather than a decorator. This should only be used if you have to support ancient versions of Python (2.2 and 2.3)
class MyClass(object):
def the_static_method(x):
print(x)
the_static_method = staticmethod(the_static_method)
MyClass.the_static_method(2) # outputs 2
This is entirely identical to the first example (using @staticmethod
), just not using the nice decorator syntax
Finally, use staticmethod
sparingly! There are very few situations where static-methods are necessary in Python, and I've seen them used many times where a separate "top-level" function would have been clearer.
The following is verbatim from the documentation::
A static method does not receive an implicit first argument. To declare a static method, use this idiom:
class C: @staticmethod def f(arg1, arg2, ...): ...
The @staticmethod form is a function decorator – see the description of function definitions in Function definitions for details.
It can be called either on the class (such as
C.f()
) or on an instance (such asC().f()
). The instance is ignored except for its class.Static methods in Python are similar to those found in Java or C++. For a more advanced concept, see
classmethod()
.For more information on static methods, consult the documentation on the standard type hierarchy in The standard type hierarchy.
New in version 2.2.
Changed in version 2.4: Function decorator syntax added.
This worked for me.
mongoose.Promise = global.Promise;

{ useNewUrlParser: true, useCreateIndex: true, useUnifiedTopology: true}).then(db => {
console.log("Database connected");
}).catch(error => console.log("Could not connect to mongo db " + error));
I was using localhost, so i changed it to:

You can use the magic of Spring's ReflectionTestUtils.setField
in order to avoid making any modifications whatsoever to your code.
The comment from Michal Stochmal provides an example:
use
ReflectionTestUtils.setField(bean, "fieldName", "value");
before invoking yourbean
method during test.
Check out this tutorial for even more information, although you probably won't need it since the method is very easy to use
UPDATE
Since the introduction of Spring 4.2.RC1 it is now possible to set a static field without having to supply an instance of the class. See this part of the documentation and this commit.

Summary:
Among those 5 methods, method 3 seems to be the fastest.
If you want an synchronous request set the async
property to false
for the request. Check out the jQuery AJAX Doc
If you want to modify the original array instead of returning a new array, use .push()
...
array1.push.apply(array1, array2);
array1.push.apply(array1, array3);
I used .apply
to push the individual members of arrays 2
and 3
at once.
or...
array1.push.apply(array1, array2.concat(array3));
To deal with large arrays, you can do this in batches.
for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
array1.push.apply(array1, to_add.slice(n, n+300));
}
If you do this a lot, create a method or function to handle it.
var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);
Object.defineProperty(Array.prototype, "pushArrayMembers", {
value: function() {
for (var i = 0; i < arguments.length; i++) {
var to_add = arguments[i];
for (var n = 0; n < to_add.length; n+=300) {
push_apply(this, slice_call(to_add, n, n+300));
}
}
}
});
and use it like this:
array1.pushArrayMembers(array2, array3);
var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_

Do you mean shapefile as in an Esri shapefile? Either way, you should be able to perform the conversion using ogr2ogr, which is available in the GDAL packages. You need the .shp
file and ideally the corresponding .dbf
file (which will provide contextual information).
Also, consider using a tool like MapShaper to reduce the complexity of your shapefiles before transforming them into KML; you'll reduce filesize substantially depending on how much detail you need.
From RFC 6750, Section 1.2:
Bearer Token
A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).
The Bearer Token or Refresh token is created for you by the Authentication server. When a user authenticates your application (client) the authentication server then goes and generates for your a Bearer Token (refresh token) which you can then use to get an access token.
The Bearer Token is normally some kind of cryptic value created by the authentication server, it isn't random it is created based upon the user giving you access and the client your application getting access.

As mentioned before use apache commons codec. It's recommended by Spring guys as well (see DigestUtils in Spring doc). E.g.:
DigestUtils.sha1Hex(b);
Definitely wouldn't use the top rated answer here.
The easiest way to freeze the UI would be to make the AJAX call synchronous.
Usually synchronous AJAX calls defeat the purpose of using AJAX because it freezes the UI, but if you want to prevent the user from interacting with the UI, then do it.
Based on @Vlad Bezden answer I use this slightly modified code because I prefer named placeholders:
String.prototype.format = function(placeholders) {
var s = this;
for(var propertyName in placeholders) {
var re = new RegExp('{' + propertyName + '}', 'gm');
s = s.replace(re, placeholders[propertyName]);
}
return s;
};
usage:
"{greeting} {who}!".format({greeting: "Hello", who: "world"})
String.prototype.format = function(placeholders) {_x000D_
var s = this;_x000D_
for(var propertyName in placeholders) {_x000D_
var re = new RegExp('{' + propertyName + '}', 'gm');_x000D_
s = s.replace(re, placeholders[propertyName]);_x000D_
} _x000D_
return s;_x000D_
};_x000D_
_x000D_
$("#result").text("{greeting} {who}!".format({greeting: "Hello", who: "world"}));
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="result"></div>

For anyone who comes here, as I did, looking for the syntax to change origin to a different location you can find that documentation here: https://help.github.com/articles/changing-a-remote-s-url/. Using git remote add
to do this will result in "fatal: remote origin already exists."
Nutshell:
git remote set-url origin https://github.com/username/repo

Got the error (in the function init) with the following code ;

}
... while using the stock browser on a Samsung galaxy Fame ( crap phone which makes it a good tester ) - userAgent ; Mozilla/5.0 (Linux; U; Android 4.1.2; en-gb; GT-S6810P Build/JZO54K) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30
The same code works everywhere else I tried including the stock browser on an older HTC phone - userAgent ; Mozilla/5.0 (Linux; U; Android 2.3.5; en-gb; HTC_WildfireS_A510e Build/GRJ90) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
The fix for this was to change
var hdr ;
to
var hdr = null ;
C#'s const
is the exact same thing as Java's final
, except it's absolutely always static
. In my opinion, it's not really necessary for a const
variable to be non-static
, but if you need to access a const
variable non-static
-ly, you can do:
class MyClass
{
private const int myLowercase_Private_Const_Int = 0;
public const int MyUppercase_Public_Const_Int = 0;
/*
You can have the `private const int` lowercase
and the `public int` Uppercase:
*/
public int MyLowercase_Private_Const_Int
{
get
{
return MyClass.myLowercase_Private_Const_Int;
}
}
/*
Or you can have the `public const int` uppercase
and the `public int` slighly altered
(i.e. an underscore preceding the name):
*/
public int _MyUppercase_Public_Const_Int
{
get
{
return MyClass.MyUppercase_Public_Const_Int;
}
}
/*
Or you can have the `public const int` uppercase
and get the `public int` with a 'Get' method:
*/
public int Get_MyUppercase_Public_Const_Int()
{
return MyClass.MyUppercase_Public_Const_Int;
}
}
Well, now I realize this question was asked 4 years ago, but since I put around 2 hours of work, consisting of trying all sorts of different ways of answering and code formatting, into this answer, I'm still posting it. :)
But, for the record, I still feel kinda silly.
Use this code:
internal void SomeFunction() {
Dictionary<string, string> formField = new Dictionary<string, string>();
formField.Add("Name", "Henry");
formField.Add("Age", "21");
string body = GetBodyStringFromDictionary(formField);
// output : Name=Henry&Age=21
}
internal string GetBodyStringFromDictionary(Dictionary<string, string> formField)
{
string body = string.Empty;
foreach (var pair in formField)
{
body += $"{pair.Key}={pair.Value}&";
}
// delete last "&"
body = body.Substring(0, body.Length - 1);
return body;
}
An example with variable (ES6):
const item = document.querySelector([data-itemid="${id}"]
);
Not sure if I get you right, but the simplest way would be something like:
<c:if test="${languageBean.locale == 'en'">
<f:selectItems value="#{customerBean.selectableCommands_limited_en}" />
</c:if>
Just a quick copy and paste from an app of mine...
HTH
og:title
is one of the open graph meta tags. og:...
properties define objects in a social graph. They are used for example by Facebook.
og:title
stands for the title of your object as it should appear within the graph (see here for more http://ogp.me/ )
This is from the lovely JavaScript library MooTools:
if (obj.nodeName){
switch (obj.nodeType){
case 1: return 'element';
case 3: return (/\S/).test(obj.nodeValue) ? 'textnode' : 'whitespace';
}
}
Try running all targets individually to check that all are running correct
run ant target name to run a target individually
e.g. ant build-project
Also the default target you specified is
project basedir="." default="build" name="iControlSilk4J"
This will only execute build-subprojects,build-project and init
I have also faced the same issue in recent past for me I have do the following commands one by one in terminal.
sudo npm uninstall -g angular-cli
sudo npm cache clean
After this run
ng -v
If still get angular-cli version 1.0.0-beta.2x.x then run the following command
which ng
It will show the ng path. Go to the path and if it is linked with any file remove the same the link and actual ng file. In my case the link is in /usr/bin/ng and actual path of ng file is /lib/node_modules/@angular/cli/bin/ng.
sudo rm -rf /lib/node_modules/@angular/cli/bin/ng
sudo rm -rf /usr/bin/ng
Next you need to install @angular/cli using
sudo npm install -g @angular/cli
Close all the terminal and run ng -v and you are on. May be it will help someone. Thanks :)
Maybe you should try
^[#;].*$
^
matches the beggining, $
the end.
Since it is bypassing CORS and CSP, this is to keep in the toolbox. Here is a variation.
This will POST a base64 encoded object at localhost:8080
, and will clean up the DOM after usage.
const theOBJECT = {message: 'Hello world!', target: 'local'}_x000D_
_x000D_
document.body.innerHTML += '<iframe id="postframe" name="hiddenFrame" width="0" height="0" border="0" style="display: none;"></iframe><form id="dynForm" target="hiddenFrame" action="http://localhost:8080/" method="post"><input type="hidden" name="somedata" value="'+btoa(JSON.stringify(theOBJECT))+'"></form>';_x000D_
document.getElementById("dynForm").submit();_x000D_
dynForm.outerHTML = ""_x000D_
postframe.outerHTML = ""
_x000D_
From the network debugger tab, we can observe a successful POST to a http://
unencrypted server from a tls/https
page.
Two possibilities :
via script task and builtin javascript engine (if using jdk >= 1.6)
<project>
<property name="propA" value="This is a value"/>
<script language="javascript">
project.setProperty('propB', project.getProperty('propA').
replace(" ", "_"));
</script>
<echo>$${propB} => ${propB}</echo>
</project>
or using Ant addon Flaka
<project xmlns:fl="antlib:it.haefelinger.flaka">
<property name="propA" value="This is a value"/>
<fl:let> propB := replace('${propA}', '_', ' ')</fl:let>
<echo>$${propB} => ${propB}</echo>
</project>
to overwrite exisiting property propA simply replace propB with propA
Both call()
and apply()
are methods which are located on Function.prototype
. Therefore they are available on every function object via the prototype chain. Both call()
and apply()
can execute a function with a specified value of the this
.
The main difference between call()
and apply()
is the way you have to pass in arguments into it. In both call()
and apply()
you pass as a first argument the object you want to be the value as this
. The other arguments differ in the following way:
call()
you have to put in the arguments normally (starting from the second argument)apply()
you have to pass in array of arguments.let obj = {_x000D_
val1: 5,_x000D_
val2: 10_x000D_
}_x000D_
_x000D_
const summation = function (val3, val4) {_x000D_
return this.val1 + this.val2 + val3 + val4;_x000D_
}_x000D_
_x000D_
console.log(summation.apply(obj, [2 ,3]));_x000D_
// first we assign we value of this in the first arg_x000D_
// with apply we have to pass in an array_x000D_
_x000D_
_x000D_
console.log(summation.call(obj, 2, 3));_x000D_
// with call we can pass in each arg individually
_x000D_
The this
value can be tricky sometimes in javascript. The value of this
determined when a function is executed not when a function is defined. If our function is dependend on a right this
binding we can use call()
and apply()
to enforce this behaviour. For example:
var name = 'unwantedGlobalName';_x000D_
_x000D_
const obj = {_x000D_
name: 'Willem',_x000D_
sayName () { console.log(this.name);}_x000D_
}_x000D_
_x000D_
_x000D_
let copiedMethod = obj.sayName;_x000D_
// we store the function in the copiedmethod variable_x000D_
_x000D_
_x000D_
_x000D_
copiedMethod();_x000D_
// this is now window, unwantedGlobalName gets logged_x000D_
_x000D_
copiedMethod.call(obj);_x000D_
// we enforce this to be obj, Willem gets logged
_x000D_

Try this if you are on ubuntu:
sudo apt-get update
sudo apt-get install build-essential libpq-dev libssl-dev openssl libffi-dev zlib1g-dev
sudo apt-get install python3-pip python3.7-dev
sudo apt-get install python3.7
In case you don't have the repository and so it fires a not-found package you first have to install this:
sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update

I would suggest not to use seaborn pointplot
for plotting. This makes things unnecessarily complicated.
Instead use matplotlib plot_date
. This allows to set labels to the plots and have them automatically put into a legend with ax.legend()
.
import matplotlib.pyplot as plt
import pandas as pd
import seaborn as sns
import numpy as np
date = pd.date_range("2017-03", freq="M", periods=15)
count = np.random.rand(15,4)
df1 = pd.DataFrame({"date":date, "count" : count[:,0]})
df2 = pd.DataFrame({"date":date, "count" : count[:,1]+0.7})
df3 = pd.DataFrame({"date":date, "count" : count[:,2]+2})
f, ax = plt.subplots(1, 1)
x_col='date'
y_col = 'count'
ax.plot_date(df1.date, df1["count"], color="blue", label="A", linestyle="-")
ax.plot_date(df2.date, df2["count"], color="red", label="B", linestyle="-")
ax.plot_date(df3.date, df3["count"], color="green", label="C", linestyle="-")
ax.legend()
plt.gcf().autofmt_xdate()
plt.show()
sns.pointplot(ax=ax,x=x_col,y=y_col,data=df1,color='blue')
sns.pointplot(ax=ax,x=x_col,y=y_col,data=df2,color='green')
sns.pointplot(ax=ax,x=x_col,y=y_col,data=df3,color='red')
ax.legend(handles=ax.lines[::len(df1)+1], labels=["A","B","C"])
ax.set_xticklabels([t.get_text().split("T")[0] for t in ax.get_xticklabels()])
plt.gcf().autofmt_xdate()
plt.show()
Another way is to use a website thumbnail/link preview service LinkPeek (even happens to show a screenshot of StackOverflow as a demo right now), URL2PNG, Browshot, Websnapr, or an alternative.
I was asking myself the same question, and I found no clear answers, so I created a simple test.
I tried to add 100 rows with duplicate primary keys and measured the time needed to process it. I am using SQL Server 2014 Developer and Entity Framework 6.1.3 with a custom repository.
Dim newE As New Employee With {.Name = "e"}
For index = 1 To 100
Dim e = employees.Select(Function(item) item.Name = "e").FirstOrDefault()
If e Is Nothing Then
employees.Insert(newE)
End If
Next
2.1 seconds
Dim newE As New Employee With {.Name = "e"}
For index = 1 To 100
Try
employees.Insert(newE)
Catch ex As Exception
End Try
Next
3.1 seconds
MockitoAnnotations & the runner have been well discussed above, so I'm going to throw in my tuppence for the unloved:
XXX mockedXxx = mock(XXX.class);
I use this because I find it a little bit more descriptive and I prefer (not out right ban) unit tests not to use member variables as I like my tests to be (as much as they can be) self contained.
You will find much information about JavaDoc at the Documentation Comment Specification for the Standard Doclet, including the information on the
tag (that you are looking for). The corresponding example from the documentation is as follows
For example, here is a comment that refers to the getComponentAt(int, int) method:
Use the {@link #getComponentAt(int, int) getComponentAt} method.
The package.class
part can be ommited if the referred method is in the current class.
Other useful links about JavaDoc are:
You can easily wrap your button tag with tag.Using Url.Action() HTML Helper this will get to navigate to one page to another.
<a href='@Url.Action("YourAction", "YourController")'>
<input type='button' value='Dummy Button' />
</a>
If you want to navigate with javascript onclick() function then use
<input type='button' value='Dummy Button' onclick='window.location = "@Url.Action("YourAction", "YourController")";' />
StringUtils is an Apache Commons project. You need to download and add the library to your classpath.
To use:
import org.apache.commons.lang3.StringUtils;
The illegal character is not in $matches[1]
, but in $xml
Try
iconv($matches[1], 'utf-8//TRANSLIT', $xml);
And showing us the input string would be nice for a better answer.
Because your %
is outside the print(...)
parentheses, you're trying to insert your variables into the result of your print
call. print(...)
returns None
, so this won't work, and there's also the small matter of you already having printed your template by this time and time travel being prohibited by the laws of the universe we inhabit.
The whole thing you want to print, including the %
and its operand, needs to be inside your print(...)
call, so that the string can be built before it is printed.
print( "a=%d,b=%d" % (f(x,n), g(x,n)) )
I have added a few extra spaces to make it clearer (though they are not necessary and generally not considered good style).
Remove the : before last-child and the :after and used
ul li:not(last-child){
content:' |';
}
Hopefully,it should work
As far as I know, the order of the repositories in your pom.xml will also decide the order of the repository access.
As for configuring repositories in settings.xml, I've read that the order of repositories is interestingly enough the inverse order of how the repositories will be accessed.
Here a post where someone explains this curiosity:
http://community.jboss.org/message/576851
Create a configuration file and put your entries there.
SERVER_PORT=10000
THREAD_POOL_COUNT=3
ROOT_DIR=/home/
You can load this file using Properties.load(fileName)
and retrieved values you get(key)
;
You have some options to handle this deprecation the right (and future proof) way, depending on which kind of drawable you are loading:
A) drawables with theme attributes
ContextCompat.getDrawable(getActivity(), R.drawable.name);
You'll obtain a styled Drawable as your Activity theme instructs. This is probably what you need.
B) drawables without theme attributes
ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);
You'll get your unstyled drawable the old way. Please note: ResourcesCompat.getDrawable()
is not deprecated!
EXTRA) drawables with theme attributes from another theme
ResourcesCompat.getDrawable(getResources(), R.drawable.name, anotherTheme);
What you could do is, create the "function" as another template file and then include that file passing the parameters to it.

simply press Alt+F5 after updating your pom.xml. This will build your project again and download all jar files
This will vary depending on your architecture and how it treats basic data types. It will also depend on whether the system requires natural alignment.

alert("This browser was found to be a % browser.", window.isMobile ? 'mobile' : 'desktop');
Somehow, the following results were returned on the following Browser Apps. Specs: iPhone 6S, iOS 10.3.1.
Safari (latest): Detected it as a mobile.
Chrome (latest): Did not detect it as a mobile.
SO, i then tested the suggestion from Lanti (https://stackoverflow.com/a/31864119/7183483), and it did return the proper results (mobile for all iOS devices, and desktop for my Mac). Therefore, i proceeded to edit it a little since it would fire twice (for both mobile and Tablet). I then noticed when testing on an iPad, that it also returned as a mobile, which makes sense, since the Parameters that Lanti uses check the OS more than anything. Therefore, i simply moved the tablet IF statement inside the mobile check, which would return mobile is the Tablet check was negative, and tablet otherwise. I then added the else clause for the mobile check to return as desktop/laptop, since both qualify, but then noticed that the browser detects CPU and OS brand. So i added what is returned in there as part of else if statement instead. To cap it, I added a cautionary else statement in case nothing was detected. See bellow, will update with a test on a Windows 10 PC soon.
Oh, and i also added a 'debugMode' variable, to easily switch between debug and normal compiling.
Dislaimer: Full credit to Lanti, also that this was not tested on Windows Tablets... which might return desktop/laptop, since the OS is pure Windows. Will check once I find a friend who uses one.

Just download this registry key and run it. It will add the necessary key to the .NET framework registry. You can have more info at this link. Search for 'Option 2' in '.NET 4.5 to 4.5.2'.
The reg file appends the following to the Registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001
This is the part of the page that is useful in case it goes broken :
" .. enable TLS 1.2 by default without modifying the source code by setting the SchUseStrongCrypto DWORD value in the following two registry keys to 1, creating them if they don't exist: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319" and "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NETFramework\v4.0.30319". Although the version number in those registry keys is 4.0.30319, the .NET 4.5, 4.5.1, and 4.5.2 frameworks also use these values. Those registry keys, however, will enable TLS 1.2 by default in all installed .NET 4.0, 4.5, 4.5.1, and 4.5.2 applications on that system. It is thus advisable to test this change before deploying it to your production servers. This is also available as a registry import file. These registry values, however, will not affect .NET applications that set the System.Net.ServicePointManager.SecurityProtocol value. "
Using zip function we can get both element and index.
countries = ['Pakistan','India','China','Russia','USA']
for index, element zip(range(0,countries),countries):
print('Index : ',index)
print(' Element : ', element,'\n')
output : Index : 0 Element : Pakistan ...

The simple solution
SELECT CAST(CollectionDate as DATETIME) + CAST(CollectionTime as DATETIME)
FROM field
I'm using XAMPP, in which there are several php.ini files.
You can find the line in the php.ini files:
;extension=php_curl.dll
Please remove ;
at the beginning of this line. And you may need to restart apache server.
In your example, it’s fine as it is: it’s simple and works. The only things I’d suggest are:
make sure your API is sending the Content-Type
header to tell the client to expect a JSON response:
header('Content-Type: application/json');
echo json_encode($response);
Other than that, an API is something that takes an input and provides an output. It’s possible to “over-engineer” things, in that you make things more complicated that need be.
If you wanted to go down the route of controllers and models, then read up on the MVC pattern and work out how your domain objects fit into it. Looking at the above example, I can see maybe a MathController
with an add()
action/method.
There are a few starting point projects for RESTful APIs on GitHub that are worth a look.
From the DOCS
Formats a number as text. Group sizing and separator and other locale-specific configurations are based on the active locale.
SYNTAX:
number_expression | number[:digitInfo[:locale]]
where expression
is a number:
digitInfo
is a string which has a following format:
{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
In the new release of dplyr
(0.6.0
awaiting in April 2017), we can also do an assignment (:=
) and pass variables as column names by unquoting (!!
) to not evaluate it
library(dplyr)
multipetalN <- function(df, n){
varname <- paste0("petal.", n)
df %>%
mutate(!!varname := Petal.Width * n)
}
data(iris)
iris1 <- tbl_df(iris)
iris2 <- tbl_df(iris)
for(i in 2:5) {
iris2 <- multipetalN(df=iris2, n=i)
}
Checking the output based on @MrFlick's multipetal
applied on 'iris1'
identical(iris1, iris2)
#[1] TRUE
Yes DOK has the right answer ... either pre-sort the results before you write the HTML (assuming it's dynamic and you are responsible for the output), or you write javascript.
The Javascript Sort method will be your friend here. Simply pull the values out of the select list, then sort it, and put them back :-)
class MyClass():
def __init__(self, a, b):
self.value1 = a
self.value2 = b
def __call__(self):
return [self.value1, self.value2]
Testing:
>>> x = MyClass('foo','bar')
>>> x()
['foo', 'bar']
You can look at the Django framework for how they create a "slug" from arbitrary text. A slug is URL- and filename- friendly.
The Django text utils define a function, slugify()
, that's probably the gold standard for this kind of thing. Essentially, their code is the following.
import unicodedata
import re
def slugify(value, allow_unicode=False):
"""
Taken from https://github.com/django/django/blob/master/django/utils/text.py
Convert to ASCII if 'allow_unicode' is False. Convert spaces or repeated
dashes to single dashes. Remove characters that aren't alphanumerics,
underscores, or hyphens. Convert to lowercase. Also strip leading and
trailing whitespace, dashes, and underscores.
"""
value = str(value)
if allow_unicode:
value = unicodedata.normalize('NFKC', value)
else:
value = unicodedata.normalize('NFKD', value).encode('ascii', 'ignore').decode('ascii')
value = re.sub(r'[^\w\s-]', '', value.lower())
return re.sub(r'[-\s]+', '-', value).strip('-_')
And the older version:
def slugify(value):
"""
Normalizes string, converts to lowercase, removes non-alpha characters,
and converts spaces to hyphens.
"""
import unicodedata
value = unicodedata.normalize('NFKD', value).encode('ascii', 'ignore')
value = unicode(re.sub('[^\w\s-]', '', value).strip().lower())
value = unicode(re.sub('[-\s]+', '-', value))
# ...
return value
There's more, but I left it out, since it doesn't address slugification, but escaping.
Try it out
el {
transform-style: preserve-3d;
}
el:after {
transform: translateZ(-1px);
}
ios will always tries to take the best image, but will fall back to other options .. so if you only have normal images in the app and it needs @2x images it will use the normal images.
if you only put @2x in the project and you open the app on a normal device it will scale the images down to display.
if you target ios7 and ios8 devices and want best quality you would need @2x and @3x for phone and normal and @2x for ipad assets, since there is no non retina phone left and no @3x ipad.
maybe it is better to create the assets in the app from vector graphic... check http://mattgemmell.com/using-pdf-images-in-ios-apps/
python2 and python3
it is good to use time module
import time
int(time.time())
1573708436
you can also use datetime module, but when you use strftime('%s'), but strftime convert time to your local time!
python2
from datetime import datetime
datetime.utcnow().strftime('%s')
python3
from datetime import datetime
datetime.utcnow().timestamp()
If ds is the DataSet, you can access the CustomerID column of the first row in the first table with something like:
DataRow dr = ds.Tables[0].Rows[0];
Console.WriteLine(dr["CustomerID"]);
As already mentioned in Angular 6 using ngModel in reactive forms is deprecated (and removed in Angular 7), so I modified the template and the component as following.
The template:
<mat-form-field>
<mat-select [formControl]="filter" multiple
[compareWith]="compareFn">
<mat-option *ngFor="let v of values" [value]="v">{{v.label}}</mat-option>
</mat-select>
</mat-form-field>
The main parts of the component (onChanges
and other details are omitted):
interface SelectItem {
label: string;
value: any;
}
export class FilterComponent implements OnInit {
filter = new FormControl();
@Input
selected: SelectItem[] = [];
@Input()
values: SelectItem[] = [];
constructor() { }
ngOnInit() {
this.filter.setValue(this.selected);
}
compareFn(v1: SelectItem, v2: SelectItem): boolean {
return compareFn(v1, v2);
}
}
function compareFn(v1: SelectItem, v2: SelectItem): boolean {
return v1 && v2 ? v1.value === v2.value : v1 === v2;
}
Note this.filter.setValue(this.selected) in ngOnInit
above.
It seems to work in Angular 6.

Here is a pure JavaScript example of picking an image file, displaying it, looping through the image properties, and then re-sizing the image from the canvas into an IMG tag and explicitly setting the re-sized image type to jpeg.
If you right click the top image, in the canvas tag, and choose Save File As, it will default to a PNG format. If you right click, and Save File as the lower image, it will default to a JPEG format. Any file over 400px in width is reduced to 400px in width, and a height proportional to the original file.
<form class='frmUpload'>
<input name="picOneUpload" type="file" accept="image/*" onchange="picUpload(this.files[0])" >
</form>
<canvas id="cnvsForFormat" width="400" height="266" style="border:1px solid #c3c3c3"></canvas>
<div id='allImgProperties' style="display:inline"></div>
<div id='imgTwoForJPG'></div>
<script>
window.picUpload = function(frmData) {
console.log("picUpload ran: " + frmData);
var allObjtProperties = '';
for (objProprty in frmData) {
console.log(objProprty + " : " + frmData[objProprty]);
allObjtProperties = allObjtProperties + "<span>" + objProprty + ": " + frmData[objProprty] + ", </span>";
};
document.getElementById('allImgProperties').innerHTML = allObjtProperties;
var cnvs=document.getElementById("cnvsForFormat");
console.log("cnvs: " + cnvs);
var ctx=cnvs.getContext("2d");
var img = new Image;
img.src = URL.createObjectURL(frmData);
console.log('img: ' + img);
img.onload = function() {
var picWidth = this.width;
var picHeight = this.height;
var wdthHghtRatio = picHeight/picWidth;
console.log('wdthHghtRatio: ' + wdthHghtRatio);
if (Number(picWidth) > 400) {
var newHeight = Math.round(Number(400) * wdthHghtRatio);
} else {
return false;
};
document.getElementById('cnvsForFormat').height = newHeight;
console.log('width: 400 h: ' + newHeight);
//You must change the width and height settings in order to decrease the image size, but
//it needs to be proportional to the original dimensions.
console.log('This is BEFORE the DRAW IMAGE');
ctx.drawImage(img,0,0, 400, newHeight);
console.log('THIS IS AFTER THE DRAW IMAGE!');
//Even if original image is jpeg, getting data out of the canvas will default to png if not specified
var canvasToDtaUrl = cnvs.toDataURL("image/jpeg");
//The type and size of the image in this new IMG tag will be JPEG, and possibly much smaller in size
document.getElementById('imgTwoForJPG').innerHTML = "<img src='" + canvasToDtaUrl + "'>";
};
};
</script>
Here is a jsFiddle:
jsFiddle Pick, display, get properties, and Re-size an image file
In jsFiddle, right clicking the top image, which is a canvas, won't give you the same save options as right clicking the bottom image in an IMG tag.
