use like this your inline css
<td width="178" rowspan="3" valign="top"
align="right" background="images/left.jpg"
style="background-repeat:background-position: right top;">
</td>
You can use
Dispatcher.Invoke(Delegate, object[])
on the Application
's (or any UIElement
's) dispatcher.
You can use it for example like this:
Application.Current.Dispatcher.Invoke(new Action(() => { /* Your code here */ }));
or
someControl.Dispatcher.Invoke(new Action(() => { /* Your code here */ }));
One should also consider another intuitive way to do this using filter()
from dplyr
. Here are some examples:
set.seed(123)
df <- data.frame(name = sample(letters, 100, TRUE),
date = sample(1:500, 100, TRUE))
library(dplyr)
filter(df, date < 50) # date less than 50
filter(df, date %in% 50:100) # date between 50 and 100
filter(df, date %in% 1:50 & name == "r") # date between 1 and 50 AND name is "r"
filter(df, date %in% 1:50 | name == "r") # date between 1 and 50 OR name is "r"
# You can also use the pipe (%>%) operator
df %>% filter(date %in% 1:50 | name == "r")
A good way for looping on an enumerable JavaScript object which could be awesome and common for ReactJS is using Object.keys
or Object.entries
with using map
function. like below:
// assume items:
const items = {
first: { name: 'phone', price: 400 },
second: { name: 'tv', price: 300 },
third: { name: 'sofa', price: 250 },
};
For looping and show some UI on ReactJS
act like below:
~~~
<div>
{Object.entries(items).map(([key, ({ name, price })]) => (
<div key={key}>
<span>name: {name}</span>
<span>price: {price}</span>
</div>
))}
</div>
Actually, I use the destructuring assignment twice, once for getting key
once for getting name
and price
.
These lines worked in my case,
ClassLoader classLoader = getClass().getClassLoader();
File fi = new File(classLoader.getResource("test.txt").getFile());
provided test.txt file inside src
You need to use use shadowView
and roundView
shadowView
roundView
shadowView
a bit inside, and its shadow needs to glow out. Adjust the insets
so that shadowView
is completely invisible behind roundView
roundView
The code
addSubviews(shadowView, roundView)
roundView.addSubviews(titleLabel, subtitleLabel, imageView)
// need inset
shadowView.pinEdges(view: self, inset: UIEdgeInsets(constraintInsets: 2))
roundView.pinEdges(view: self)
do {
shadowView.backgroundColor = .white // need background
let layer = shadowView.layer
layer.shadowColor = UIColor.black.cgColor
layer.shadowRadius = 3
layer.shadowOffset = CGSize(width: 3, height: 3)
layer.shadowOpacity = 0.7
layer.shouldRasterize = true
}
do {
roundView.backgroundColor = .white
let layer = roundView.layer
layer.masksToBounds = true
layer.cornerRadius = 5
}
Or you can just do below without specifying clipToBounds/maskToBounds
layer.shadowColor = UIColor.gray.cgColor
layer.shadowOffset = CGSize(width: 3, height: 3)
layer.shadowOpacity = 0.8
This will do:
#include <fstream>
#include <iostream>
using std::fstream;
int main(int argc, char *argv[]) {
fstream file;
file.open("test.txt",std::ios::out);
file << fflush;
file.close();
}

You can use Dispatcher.Invoke to update your GUI from a secondary thread.
Here is an example:
private void Window_Loaded(object sender, RoutedEventArgs e)
{
new Thread(DoSomething).Start();
}
public void DoSomething()
{
for (int i = 0; i < 100000000; i++)
{
this.Dispatcher.Invoke(()=>{
textbox.Text=i.ToString();
});
}
}
As for someone don't like gray background like academic editor, try this:
p <- p + theme_bw()
p
<script type="text/javascript">
function report(func)
{
func();
}
function daily()
{
alert('daily');
}
function monthly()
{
alert('monthly');
}
</script>
I found this method to be quite useful. However it will convert your date/time format to just date but never the less it does the job for what I need it for. (I just needed to display the date on a report, the time was irrelevant).
CAST(start_date AS DATE)
UPDATE
(Bear in mind I'm a trainee ;))
I figured an easier way to do this IF YOU'RE USING SSRS.
It's easier to actually change the textbox properties where the field is located in the report. Right click field>Number>Date and select the appropriate format!
With Java 8, you can do this.
final int[] arr = {1, 2, 3};
final PrimitiveIterator.OfInt i1 = Arrays.stream(arr).iterator();
final PrimitiveIterator.OfInt i2 = IntStream.of(arr).iterator();
final Iterator<Integer> i3 = IntStream.of(arr).boxed().iterator();
In case it helps someone else, I was able to convert to an array by doing something like this,
JSONObject jsonObject = (JSONObject)new JSONParser().parse(jsonString);
((JSONArray) jsonObject).toArray()
...or you should be able to get the length
((JSONArray) myJsonArray).toArray().length
Note for anyone running Vagrant: this can be caused by a bug with their shared folders. Specify NFS for your shared folders in your Vagrantfile to avoid this happening.
Simply adding type: "nfs"
to the end will do the trick, like so:
config.vm.synced_folder ".", "/vagrant", type: "nfs"
use new toolbar in support library design your actionbar as your own or use below code
Inflating Textview is not an good option try Spannable String builder
Typeface font2 = Typeface.createFromAsset(getAssets(), "fonts/<your font in assets folder>");
SpannableStringBuilder SS = new SpannableStringBuilder("MY Actionbar Tittle");
SS.setSpan (new CustomTypefaceSpan("", font2), 0, SS.length(),Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
actionBar.setTitle(ss);
copy below class
public class CustomTypefaceSpan extends TypefaceSpan{
private final Typeface newType;
public CustomTypefaceSpan(String family, Typeface type) {
super(family);
newType = type;
}
@Override
public void updateDrawState(TextPaint ds) {
applyCustomTypeFace(ds, newType);
}

public void updateMeasureState(TextPaint paint) {
applyCustomTypeFace(paint, newType);
}
private static void applyCustomTypeFace(Paint paint, Typeface tf) {
int oldStyle;
Typeface old = paint.getTypeface();
if (old == null) {
oldStyle = 0;
} else {
oldStyle = old.getStyle();
}
int fake = oldStyle & ~tf.getStyle();
if ((fake & Typeface.BOLD) != 0) {
paint.setFakeBoldText(true);
}
if ((fake & Typeface.ITALIC) != 0) {
paint.setTextSkewX(-0.25f);
}
paint.setTypeface(tf);
}
}

If you are expecting double, decimal, float, integer
why not use the one which accomodates all namely decimal (128 bits are enough for most numbers you are looking at).
instead of (double)value
use decimal.Parse(value.ToString())
or Convert.ToDecimal(value)
Late answer, I know but I too wanted this so I could log the SQL. The following is short and meets my needs.
The following produces SQL you can copy/paste in SSMS (it replaces the parameters with the values properly). You can add more types but this meets all I use in this case.
private static void LogSQL(SqlCommand cmd)
{
string query = cmd.CommandText;
foreach (SqlParameter prm in cmd.Parameters)
{
switch (prm.SqlDbType)
{
case SqlDbType.Bit:
int boolToInt = (bool)prm.Value ? 1 : 0;
query = query.Replace(prm.ParameterName, string.Format("{0}", (bool)prm.Value ? 1 : 0));
break;
case SqlDbType.Int:
query = query.Replace(prm.ParameterName, string.Format("{0}", prm.Value));
break;
case SqlDbType.VarChar:
query = query.Replace(prm.ParameterName, string.Format("'{0}'", prm.Value));
break;
default:
query = query.Replace(prm.ParameterName, string.Format("'{0}'", prm.Value));
break;
}
}
// the following is my how I write to my log - your use will vary
logger.Debug("{0}", query);
return;
}
Now I can log the SQL just before I execute it:
LogSQL(queryCmd)
queryCmd.ExecuteNonQuery()

Before dealing with the iterables and iterator the major factor that decide the iterable and iterator is sequence
Sequence: Sequence is the collection of data
Iterable: Iterable are the sequence type object that support __iter__
method.
Iter method: Iter method take sequence as an input and create an object which is known as iterator
Iterator: Iterator are the object which call next method and transverse through the sequence. On calling the next method it returns the object that it traversed currently.
example:
x=[1,2,3,4]
x is a sequence which consists of collection of data
y=iter(x)
On calling iter(x)
it returns a iterator only when the x object has iter method otherwise it raise an exception.If it returns iterator then y is assign like this:
y=[1,2,3,4]
As y is a iterator hence it support next()
method
On calling next method it returns the individual elements of the list one by one.
After returning the last element of the sequence if we again call the next method it raise an StopIteration error
example:
>>> y.next()
1
>>> y.next()
2
>>> y.next()
3
>>> y.next()
4
>>> y.next()
StopIteration
The 2nd parameter in the get
call is a config object. You want something like this:
$http
.get('accept.php', {
params: {
source: link,
category_id: category
}
})
.success(function (data,status) {
$scope.info_show = data
});
See the Arguments section of http://docs.angularjs.org/api/ng.$http for more detail
Variables have scope, so yes it is appropriate to have variables that are specific to your function. You don't always have to be explicit about their definition; usually you can just use them. Only if you want to do something specific to the type of the variable, like append for a list, do you need to define them before you start using them. Typical example of this.
list = []
for i in stuff:
list.append(i)
By the way, this is not really a good way to setup the list. It would be better to say:
list = [i for i in stuff] # list comprehension
...but I digress.
Your other question. The custom object should be a class itself.
class CustomObject(): # always capitalize the class name...this is not syntax, just style.
pass
customObj = CustomObject()
You can force the annotation library in your test using:
androidTestCompile 'com.android.support:support-annotations:23.1.0'
Something like this:
// Force usage of support annotations in the test app, since it is internally used by the runner module.
androidTestCompile 'com.android.support:support-annotations:23.1.0'
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test:rules:0.4.1'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
androidTestCompile 'com.android.support.test.espresso:espresso-web:2.2.1'
Another solution is to use this in the top level file:
configurations.all {
resolutionStrategy.force 'com.android.support:support-annotations:23.1.0'
}
The reliable solution is catching the ObjectDisposedException.
The solution to write your overridden implementation of the Dispose method doesn't work, since there is a race condition between the thread calling Dispose method and the one accessing to the object: after having checked the hypothetic IsDisposed property , the object could be really disposed, throwing the exception all the same.
Another approach could be exposing a hypothetic event Disposed (like this), which is used to notify about the disposing object to every object interested, but this could be difficoult to plan depending on the software design.
Change the wrapping from "onload
" to "No wrap - in <body>

The function defined has a different scope.

I think that @ is bad decision, and make some changes to solution from deer.org.ua;
You can easily do this using node-fetch if you are pulling from http(s) URIs.
From the readme:
fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png')
.then(res => res.buffer())
.then(buffer => console.log)
You can do this using Input.setSelectionRange
, part of the Range API for interacting with text selections and the text cursor:
var searchInput = $('#Search');
// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;
searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);
Demo: Fiddle
If you are in a browser environment you can also use btoa.
btoa
is a function which takes a string as argument and produces a Base64 encoded ASCII string. Its supported by 97% of browsers.
Example:
> "Basic " + btoa("billy"+":"+"secretpassword")
< "Basic YmlsbHk6c2VjcmV0cGFzc3dvcmQ="
You can then add Basic YmlsbHk6c2VjcmV0cGFzc3dvcmQ=
to the authorization
header.
Note that the usual caveats about HTTP BASIC auth apply, most importantly if you do not send your traffic over https an eavesdropped can simply decode the Base64 encoded string thus obtaining your password.
This security.stackexchange.com answer gives a good overview of some of the downsides.

If you have date-fns
installed, you could use formatISO function
const date = new Date(2019, 0, 2)
import { formatISO } from 'date-fns'
formatISO(date, { representation: 'date' }) // '2019-01-02' string
As a newbie in React world, I came across a similar issues where I could not edit
the textarea and struggled
with binding. It's worth knowing about controlled
and uncontrolled
elements when it comes to react.
The value of the following uncontrolled textarea
cannot be changed because of value
<textarea type="text" value="some value"
onChange={(event) => this.handleOnChange(event)}></textarea>
The value of the following uncontrolled textarea
can be changed because of use of defaultValue
or no value attribute
<textarea type="text" defaultValue="sample"
onChange={(event) => this.handleOnChange(event)}></textarea>
<textarea type="text"
onChange={(event) => this.handleOnChange(event)}></textarea>
The value of the following controlled textarea
can be changed because of how
value is mapped to a state as well as the onChange
event listener
<textarea value={this.state.textareaValue}
onChange={(event) => this.handleOnChange(event)}></textarea>
Here is my solution using different syntax. I prefer the auto-bind
than manual binding however, if I were to not use {(event) => this.onXXXX(event)}
then that would cause the content of textarea
to be not editable OR the event.preventDefault()
does not work as expected. Still a lot to learn I suppose.
class Editor extends React.Component {
constructor(props) {
super(props)
this.state = {
textareaValue: ''
}
}
handleOnChange(event) {
this.setState({
textareaValue: event.target.value
})
}
handleOnSubmit(event) {
event.preventDefault();
this.setState({
textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
})
}
render() {
return <div>
<form onSubmit={(event) => this.handleOnSubmit(event)}>
<textarea rows={10} cols={30} value={this.state.textareaValue}
onChange={(event) => this.handleOnChange(event)}></textarea>
<br/>
<input type="submit" value="Save"/>
</form>
</div>
}
}
ReactDOM.render(<Editor />, document.getElementById("content"));
The versions of libraries are

I was seeing this same error when trying to save an excel file. The code worked fine when I was using MS Office 2003, but after upgrading to MS Office 2007 I started seeing this. It would happen anytime I tried to save an Excel file to a server or remote fie share.
My solution, though rudimentary, worked well. I just had the program save the file locally, like to the user's C:\ drive. Then use the "System.IO.File.Copy(File, Destination, Overwrite)" method to move the file to the server. Then you can delete the file on the C:\ drive.
Works great, and simple. But admittedly not the most elegant approach.
Hope this helps! I was having a ton of trouble finding any solutions on the web till this idea popped into my head.
If you are using Notepad++ editor (like the tag of the question suggests), you can use the great "Find in Files" functionality.
Go to Search → Find in Files (Ctrl+Shift+F for the keyboard addicted) and enter:
Find What = (cat|town)
Filters = *.txt
Directory = enter the path of the directory you want to search in. You can check Follow current doc.
to have the path of the current file to be filled.
Search mode = Regular Expression
It depends on the GC your java is using. Parallel GCs might work better on larger memory settings - I'm no expert on that though.
In general, if you have larger memory the less frequent it needs to be GC-ed - there is lots of room for garbage. However, when it comes to a GC, the GC has to work on more memory - which in turn might be slower.
For basic URL resolution, use a command line fetcher like wget
or curl
to do the testing, rather than a manual browser. Then you don't have to clear any cache; just up arrow and Enter in a shell to re-run your test fetches.

Tick 'Full Index Enabled' and then 'Rebuild Index' of the central repository in 'Global Repositories' under Window > Show View > Other > Maven > Maven Repositories
, and it should work.
The rebuilding may take a long time depending on the speed of your internet connection, but eventually it works.
For any number validation you have to use different different range validation as per your requirements :
For Integer
[Range(0, int.MaxValue, ErrorMessage = "Please enter valid integer Number")]
for float
[Range(0, float.MaxValue, ErrorMessage = "Please enter valid float Number")]
for double
[Range(0, double.MaxValue, ErrorMessage = "Please enter valid doubleNumber")]
Echoing Data If It Exists
Sometimes you may wish to echo a variable, but you aren't sure if the variable has been set. We can express this in verbose PHP code like so:
{{ isset($name) ? $name : 'Default' }}
However, instead of writing a ternary statement, Blade provides you with the following convenient short-cut:
{{ $name or 'Default' }}
In this example, if the $name variable exists, its value will be displayed. However, if it does not exist, the word Default will be displayed.
Wrap a Missing Filter in the Must-Not section of a Bool Filter. It will only return documents where the field exists, and if you set the "null_value" property to true, values that are explicitly not null.
{
"query":{
"filtered":{
"query":{
"match_all":{}
},
"filter":{
"bool":{
"must":{},
"should":{},
"must_not":{
"missing":{
"field":"field1",
"existence":true,
"null_value":true
}
}
}
}
}
}
}
Probably because you can't have part of an iterable. Also, floats
are imprecise.
Drop the hash - that's for identifying the id attribute.
Check-all checkbox should be updated itself under certain conditions. Try to click on '#select-all-teammembers' then untick few items and click select-all again. You can see inconsistency. To prevent it use the following trick:
var checkBoxes = $('input[name=recipients\\[\\]]');
$('#select-all-teammembers').click(function() {
checkBoxes.prop("checked", !checkBoxes.prop("checked"));
$(this).prop("checked", checkBoxes.is(':checked'));
});
BTW all checkboxes DOM-object should be cached as described above.
You can also dynamically create a class by using DynamicObject.
public class DynamicClass : DynamicObject
{
private Dictionary<string, KeyValuePair<Type, object>> _fields;
public DynamicClass(List<Field> fields)
{
_fields = new Dictionary<string, KeyValuePair<Type, object>>();
fields.ForEach(x => _fields.Add(x.FieldName,
new KeyValuePair<Type, object>(x.FieldType, null)));
}
public override bool TrySetMember(SetMemberBinder binder, object value)
{
if (_fields.ContainsKey(binder.Name))
{
var type = _fields[binder.Name].Key;
if (value.GetType() == type)
{
_fields[binder.Name] = new KeyValuePair<Type, object>(type, value);
return true;
}
else throw new Exception("Value " + value + " is not of type " + type.Name);
}
return false;
}
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
result = _fields[binder.Name].Value;
return true;
}
}
I store all class fields in a dictionary _fields
together with their types and values. The both methods are to can get or set value to some of the properties. You must use the dynamic
keyword to create an instance of this class.
The usage with your example:
var fields = new List<Field>() {
new Field("EmployeeID", typeof(int)),
new Field("EmployeeName", typeof(string)),
new Field("Designation", typeof(string))
};
dynamic obj = new DynamicClass(fields);
//set
obj.EmployeeID = 123456;
obj.EmployeeName = "John";
obj.Designation = "Tech Lead";
obj.Age = 25; //Exception: DynamicClass does not contain a definition for 'Age'
obj.EmployeeName = 666; //Exception: Value 666 is not of type String
//get
Console.WriteLine(obj.EmployeeID); //123456
Console.WriteLine(obj.EmployeeName); //John
Console.WriteLine(obj.Designation); //Tech Lead
Edit: And here is how looks my class Field
:
public class Field
{
public Field(string name, Type type)
{
this.FieldName = name;
this.FieldType = type;
}
public string FieldName;
public Type FieldType;
}
In windows,
use it :
func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if editingStyle == UITableViewCellEditingStyle.Delete {
langData.removeAtIndex(indexPath.row) //langData is array from i delete values
tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Automatic)
}
}
hope it helps you
None of the above solutions worked for me. The following however works like a charm:-
override fun setUserVisibleHint(isVisibleToUser: Boolean)
type C:\temp\test.bat>C:\temp\test.log
No, see this question which I asked - Upcasting in .NET using generics
The best way is to make a default constructor on the class, construct and then call an Initialise
method
You are indeed passing the first data item to the each function.
Pass data.programs to the each function instead. Change the code to as below:
<script>
$(document).ready(function() {
var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };
$.each(data.programs, function(key,val) {
alert(key+val);
});
});
</script>
I have come across this very useful article about async
and void
written by Jérôme Laban:
https://jaylee.org/archive/2012/07/08/c-sharp-async-tips-and-tricks-part-2-async-void.html
The bottom line is that an async+void
can crash the system and usually should be used only on the UI side event handlers.
The reason behind this is the Synchronization Context used by the AsyncVoidMethodBuilder, being none in this example. When there is no ambient Synchronization Context, any exception that is unhandled by the body of an async void method is rethrown on the ThreadPool. While there is seemingly no other logical place where that kind of unhandled exception could be thrown, the unfortunate effect is that the process is being terminated, because unhandled exceptions on the ThreadPool effectively terminate the process since .NET 2.0. You may intercept all unhandled exception using the AppDomain.UnhandledException event, but there is no way to recover the process from this event.
When writing UI event handlers, async void methods are somehow painless because exceptions are treated the same way found in non-async methods; they are thrown on the Dispatcher. There is a possibility to recover from such exceptions, with is more than correct for most cases. Outside of UI event handlers however, async void methods are somehow dangerous to use and may not that easy to find.

Recently I had this problem after upgrading node.js (and inevitably npm) to the newest version:
> npm --version
< 2.0.0-alpha-5
Note: I didn't ask for an unstable version, I just got it after brew install npm
on OSX.
Downgrading npm fixed the problem for me.
The easiest way to install the stable npm is npm install -g npm
but it might not work under some circumstances and downgrade of node.js might be needed then.
I have solved this issue,

If you are using spring-boot for server side coding then please add a servlet filter and add the following code of your spring-boot application. It should work. Adding "Access-Control-Allow-Headers", "*"
is mandatory. Creation of proxy.conf.json is not needed.
@Component
@Order(1)
public class MyProjectFilter implements Filter {
@Override
public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");
response.setHeader("Access-Control-Allow-Methods", "GET,POST,PATCH,DELETE,PUT,OPTIONS");
response.setHeader("Access-Control-Allow-Headers", "*");
response.setHeader("Access-Control-Max-Age", "86400");
chain.doFilter(req, res);
}
}
I would like to add that the height of the tree is the length of the longest path from the root to a leaf, and that the height of a node is the length of the longest path from that node to a leaf. The path means the number of nodes we encounter while traversing the tree between two nodes. In order to achieve O(log n) time complexity, the tree should be balanced, meaning that the difference of the height between the children of any node should be less than or equal to 1. Therefore, trees do not always guarantee a time complexity O(log n), unless they are balanced. Actually in some cases, the time complexity of searching in a tree can be O(n) in the worst case scenario.
You can take a look at the balance trees such as AVL tree
. This one works on balancing the tree while inserting data in order to keep a time complexity of (log n) while searching in the tree.

}
this.setState({ detailSummaryList: summaryList });
}
There's another, more accessible solution: Don't put the action on your buttons. There's a lot of functionality built into forms already. Instead of handling button presses, handle form submissions and resets. Simply add onSubmit={handleSubmit}
and onReset={handleReset}
to your form
elements.
To stop the actual submission just include event
in your function and an event.preventDefault();
to stop the default submission behavior. Now your form behaves correctly from an accessibility standpoint and you're handling any form of submission the user might take.
Days
ClassUsing the Days
class with the withTimeAtStartOfDay
method should work:
Days.daysBetween(start.withTimeAtStartOfDay() , end.withTimeAtStartOfDay() ).getDays()
According to RFC 4337 § 2, video/mp4
is indeed the correct Content-Type for MPEG-4 video.
Generally, you can find official MIME definitions by searching for the file extension and "IETF" or "RFC". The RFC (Request for Comments) articles published by the IETF (Internet Engineering Taskforce) define many Internet standards, including MIME types.
To solve this problem in Excel, usually I would just type in the literal row number of the cell above, e.g., if I'm typing in Cell A7
, I would use the formula =A6
. Then if I copied that formula to other cells, they would also use the row of the previous cell.
Another option is to use Indirect()
, which resolves the literal statement inside to be a formula. You could use something like:
=INDIRECT("A" & ROW() - 1)
The above formula will resolve to the value of the cell in column A
and the row that is one less than that of the cell which contains the formula.
You can justify the navbar contents by using:
@media (min-width: 768px){
.navbar-nav{
margin: 0 auto;
display: table;
table-layout: fixed;
float: none;
}
}

You need to replace $(element).show(); and (element).show(); with $scope.loadingStatus = 'true'; and $scope.loadingStatus = 'false';
Than, you need to use this variable to set the ng-show attribute of the element.
I came across this post searching how to add an extra directory for resources. I found a solution that may be useful to someone. Here is my final configuration to get that:

}
}
}
Quite a bit late, but a duplicate answer that doesn't require altering the padding or adding extra divs can be found here: Have an issue with box-shadow Inset bottom only. It says, "Use a negative value for the fourth length which defines the spread distance. This is often overlooked, but supported by all major browsers"
From the answerer's fiddle:
box-shadow: inset 0 -10px 10px -10px #000000;
var num = new Number(14.12);
console.log(num.toPrecision(2));//outputs 14
console.log(num.toPrecision(3));//outputs 14.1
console.log(num.toPrecision(4));//outputs 14.12
console.log(num.toPrecision(5));//outputs 14.120
Tyson's answer is correct for changing the status bar color to white in UINavigationController
.
If anyone want's to accomplish the same result by writing the code in AppDelegate
then use below code and write it inside AppDelegate's
didFinishLaunchingWithOptions
method.
And don't forget to set the UIViewControllerBasedStatusBarAppearance
to YES
in the .plist file, else the change will not reflect.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// status bar appearance code
[[UINavigationBar appearance] setBarStyle:UIBarStyleBlack];
return YES;
}
Your include paths indicate that you should be compiling against the system's OpenSSL installation. You shouldn't have the .h
files in your package directory - it should be picking them up from /usr/include/openssl
.
The plain OpenSSL package (libssl
) doesn't include the .h
files - you need to install the development package as well. This is named libssl-dev
on Debian, Ubuntu and similar distributions, and libssl-devel
on CentOS, Fedora, Red Hat and similar.
Use the global flag:
var name = name.replace(/[^a-zA-Z ]/g, "");

I had the same error in a demo app that was concerned with security and login state. None of the other solutions helped, but simply opening a new anonymous browser window did the trick.
Basically, there were cookies and tokens left from a previous version of the app which put AngularJS in a state that it was never supposed to reach. Hence the areq
assertions failed.
Just found the solution to this for myself. What you want to set is the maxIdleTime of WebSocketServlet, in millis. How to do that depends on how you config your servlet. With Guice ServletModule you can do something like this for timeout of 10 hours:
serve("ws").with(MyWSServlet.class,
new HashMap<String, Sring>(){{ put("maxIdleTime", TimeUnit.HOURS.toMillis(10) + ""); }});
Anything <0 is infinite idle time I believe.
My solution is to cover all the range of diacritics:
([A-z0-9À-ž\s]){2,}
A-z
- this is for all latin characters
0-9
- this is for all digits
À-ž
- this is for all diacritics
\s
- this is for spaces
{2,}
- string needs to be at least 2 characters long

I'd suggest doing something similar to:
function show_sub(cat) {
if (!cat) {
return false;
}
else if (document.getElementById(cat)) {
var parent = document.getElementById(cat),
sub = parent.getElementsByClassName('sub');
if (sub[0].style.display == 'inline'){
sub[0].style.display = 'none';
}
else {
sub[0].style.display = 'inline';
}
}
}
document.getElementById('cat').onclick = function(){
show_sub(this.id);
};????
Though the above relies on the use of a class
rather than a name
attribute equal to sub
.
As to why your original version "didn't work" (not, I must add, a particularly useful description of the problem), all I can suggest is that, in Chromium, the JavaScript console reported that:
Uncaught TypeError: Object # has no method 'getElementsByName'.
One approach to working around the older-IE family's limitations is to use a custom function to emulate getElementsByClassName()
, albeit crudely:
function eBCN(elem,classN){
if (!elem || !classN){
return false;
}
else {
var children = elem.childNodes;
for (var i=0,len=children.length;i<len;i++){
if (children[i].nodeType == 1
&&
children[i].className == classN){
var sub = children[i];
}
}
return sub;
}
}
function show_sub(cat) {
if (!cat) {
return false;
}
else if (document.getElementById(cat)) {
var parent = document.getElementById(cat),
sub = eBCN(parent,'sub');
if (sub.style.display == 'inline'){
sub.style.display = 'none';
}
else {
sub.style.display = 'inline';
}
}
}
var D = document,
listElems = D.getElementsByTagName('li');
for (var i=0,len=listElems.length;i<len;i++){
listElems[i].onclick = function(){
show_sub(this.id);
};
}?
Why do people keep confusing php and javascript?
PHP is SERVER SIDE
JAVASCRIPT (like onclick) is CLIENT SIDE
You will have to use just javascript to redirect. Otherwise if you want PHP involved you can use an AJAX call to log a hit or whatever you like to send back a URL or additional detail.
You can also perform case insensitive searches using search/match without the IGNORECASE flag (tested in Python 2.7.3):
re.search(r'(?i)test', 'TeSt').group() ## returns 'TeSt'
re.match(r'(?i)test', 'TeSt').group() ## returns 'TeSt'
There are several tools which can import Excel to SQL Server.
I am using DbTransfer (http://www.dbtransfer.com/Products/DbTransfer) to do the job. It's primarily focused on transfering data between databases and excel, xml, etc...
I have tried the openrowset method and the SQL Server Import / Export Assitant before. But I found these methods to be unnecessary complicated and error prone in constrast to doing it with one of the available dedicated tools.
The accepted answer (its image) is wrong, at least now in QT5. Instead you should assign a layout to the root object/widget (pointing to the aforementioned image, it should be the MainWindow
instead of centralWidget
). Also note that you must have at least one QObject
created beneath it for this to work. Do this and your ui will become responsive to window resizing.
You can write SQL query in any of your favorite database e.g. MySQL, Microsoft SQL Server or Oracle. You can also use database specific feature e.g. TOP, LIMIT or ROW_NUMBER to write SQL query, but you must also provide a generic solution which should work on all database. In fact, there are several ways to find second highest salary and you must know a couple of them e.g. in MySQL without using the LIMIT keyword, in SQL Server without using TOP and in Oracle without using RANK and ROWNUM.
Generic SQL query:
SELECT
MAX(salary)
FROM
Employee
WHERE
Salary NOT IN (
SELECT
Max(Salary)
FROM
Employee
);
Another solution which uses sub query instead of NOT IN clause. It uses <
operator.
SELECT
MAX(Salary)
FROM
Employee
WHERE
Salary < (
SELECT
Max(Salary)
FROM
Employee
);
Using the Application Class
Depending on what you're doing in your initialization you could consider creating a new class that extends Application
and moving your initialization code into an overridden onCreate
method within that class.
public class MyApplicationClass extends Application {
@Override
public void onCreate() {
super.onCreate();
// TODO Put your application initialization code here.
}
}
The onCreate
in the application class is only called when the entire application is created, so the Activity restarts on orientation or keyboard visibility changes won't trigger it.
It's good practice to expose the instance of this class as a singleton and exposing the application variables you're initializing using getters and setters.
NOTE: You'll need to specify the name of your new Application class in the manifest for it to be registered and used:
<application
android:name="com.you.yourapp.MyApplicationClass"
Reacting to Configuration Changes [UPDATE: this is deprecated since API 13; see the recommended alternative]
As a further alternative, you can have your application listen for events that would cause a restart – like orientation and keyboard visibility changes – and handle them within your Activity.
Start by adding the android:configChanges
node to your Activity's manifest node
<activity android:name=".MyActivity"
android:configChanges="orientation|keyboardHidden"
android:label="@string/app_name">
or for Android 3.2 (API level 13) and newer:
<activity android:name=".MyActivity"
android:configChanges="keyboardHidden|orientation|screenSize"
android:label="@string/app_name">
Then within the Activity override the onConfigurationChanged
method and call setContentView
to force the GUI layout to be re-done in the new orientation.
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
setContentView(R.layout.myLayout);
}
I had the same error in my Eclipse IDE. But it seems it is an ignorable error. I pressed Ok on the error dialogue box & continued. My breakpoints were reached & i was able to debug further.
I'd suggest to use .nth(0)
rather than .first()
if you need to get the first row.
The difference between them is how they handle NaNs, so .nth(0)
will return the first row of group no matter what are the values in this row, while .first()
will eventually return the first not NaN
value in each column.
E.g. if your dataset is :
df = pd.DataFrame({'id' : [1,1,1,2,2,3,3,3,3,4,4],
'value' : ["first","second","third", np.NaN,
"second","first","second","third",
"fourth","first","second"]})
>>> df.groupby('id').nth(0)
value
id
1 first
2 NaN
3 first
4 first
And
>>> df.groupby('id').first()
value
id
1 first
2 second
3 first
4 first
As @moeffju suggests, this can be achieved with CSS. The issue I ran into (which I'm surprised I haven't seen discussed) is the trick of overlapping previous elements with padding or a transparent border prevents hover and click actions at the bottom of those sections because the following one comes higher in the z-order.
The best fix I found was to place section content in a div
that is at z-index: 1
:
// Apply to elements that serve as anchors
.offset-anchor {
border-top: 75px solid transparent;
margin: -75px 0 0;
-webkit-background-clip: padding-box;
-moz-background-clip: padding;
background-clip: padding-box;
}
// Because offset-anchor causes sections to overlap the bottom of previous ones,
// we need to put content higher so links aren't blocked by the transparent border.
.container {
position: relative;

?+?+?/?/?/? will let you navigate split panes in the direction of the arrow, i.e. when using ?+D to split panes vertically, ?+?+? and ?+?+? will let you switch between the panes.
Mistake in original post is acquire() call set inside the try loop. Here is a correct approach to use "binary" semaphore (Mutex):
semaphore.acquire();
try {
//do stuff
} catch (Exception e) {
//exception stuff
} finally {
semaphore.release();
}
I know replaceAll method is much easier but I wanted to post this as well.

I was having exactly the same problem.I went to my IE setting->LAN Settings.Then copied the Address as host and port as the port and it worked. Following is the snapshot of the proxies tag in the Settings.xml that I changed.
<proxy>
<id>optional</id>
<active>true</active>
<protocol>http</protocol>
<!--username>proxyuser</username>
<password>proxypass</password-->
<host>webtitan</host>

<!--nonProxyHosts>local.net|some.host.com</nonProxyHosts-->
</proxy>
1.) Check here. Basically do this:
Function FileExists(ByVal FileToTest As String) As Boolean
FileExists = (Dir(FileToTest) <> "")
End Function
I'll leave it to you to figure out the various error handling needed but these are among the error handling things I'd be considering:
2.) How To Delete a File. Look at this. Basically use the Kill command but you need to allow for the possibility of a file being read-only. Here's a function for you:
Sub DeleteFile(ByVal FileToDelete As String)
If FileExists(FileToDelete) Then 'See above
' First remove readonly attribute, if set
SetAttr FileToDelete, vbNormal
' Then delete the file
Kill FileToDelete
End If
End Sub
Again, I'll leave the error handling to you and again these are the things I'd consider:
Should this behave differently for a directory vs. a file? Should a user have to explicitly have to indicate they want to delete a directory?
Do you want the code to automatically reset the read-only attribute or should the user be given some sort of indication that the read-only attribute is set?
EDIT: Marking this answer as community wiki so anyone can modify it if need be.
Go to Path C:\ProgramData\Oracle\Java\javapath (This path is in my case might be different in your case). Rename the folder ORACLE with other name line ORACLE_OLD. And Restart the STS/IDE . This works for me
You have to start a service in your Application class to run it always. If you do that, your service will be always running. Even though user terminates your app from task manager or force stop your app, it will start running again.
Create a service:
public class YourService extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// do your jobs here
return super.onStartCommand(intent, flags, startId);
}
}
Create an Application class and start your service:
public class App extends Application {
@Override
public void onCreate() {
super.onCreate();
startService(new Intent(this, YourService.class));
}
}
Add "name" attribute into the "application" tag of your AndroidManifest.xml
android:name=".App"
Also, don't forget to add your service in the "application" tag of your AndroidManifest.xml
<service android:name=".YourService"/>
And also this permission request in the "manifest" tag (if API level 28 or higher):
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
UPDATE
After Android Oreo, Google introduced some background limitations. Therefore, this solution above won't work probably. When a user kills your app from task manager, Android System will kill your service as well. If you want to run a service which is always alive in the background. You have to run a foreground service with showing an ongoing notification. So, edit your service like below.
public class YourService extends Service {
private static final int NOTIF_ID = 1;
private static final String NOTIF_CHANNEL_ID = "Channel_Id";
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId){
// do your jobs here
startForeground();
return super.onStartCommand(intent, flags, startId);
}
private void startForeground() {
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);
startForeground(NOTIF_ID, new NotificationCompat.Builder(this,
NOTIF_CHANNEL_ID) // don't forget create a notification channel first
.setOngoing(true)
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle(getString(R.string.app_name))
.setContentText("Service is running background")
.setContentIntent(pendingIntent)
.build());
}
}
EDIT: RESTRICTED OEMS
Unfortunately, some OEMs (Xiaomi, OnePlus, Samsung, Huawei etc.) restrict background operations due to provide longer battery life. There is no proper solution for these OEMs. Users need to allow some special permissions that are specific for OEMs or they need to add your app into whitelisted app list by device settings. You can find more detail information from https://dontkillmyapp.com/.
If background operations are an obligation for you, you need to explain it to your users why your feature is not working and how they can enable your feature by allowing those permissions. I suggest you to use AutoStarter library (https://github.com/judemanutd/AutoStarter) in order to redirect your users regarding permissions page easily from your app.
By the way, if you need to run some periodic work instead of having continuous background job. You better take a look WorkManager (https://developer.android.com/topic/libraries/architecture/workmanager)
Modifying, or more correctly, adding additional HTTP headers is a great code debugging tool if nothing else.
When a URL request returns a redirect or an image there is no html "page" to temporarily write the results of debug code to - at least not one that is visible in a browser.
One approach is to write the data to a local log file and view that file later. Another is to temporarily add HTTP headers reflecting the data and variables being debugged.
I regularly add extra HTTP headers like X-fubar-somevar: or X-testing-someresult: to test things out - and have found a lot of bugs that would have otherwise been very difficult to trace.
Here's a recursive solution:
function closest(el, selector, stopSelector) {
if(!el || !el.parentElement) return null
else if(stopSelector && el.parentElement.matches(stopSelector)) return null
else if(el.parentElement.matches(selector)) return el.parentElement
else return closest(el.parentElement, selector, stopSelector)
}
The related_name
attribute specifies the name of the reverse relation from the User
model back to your model.
If you don't specify a related_name
, Django automatically creates one using the name of your model with the suffix _set
, for instance User.map_set.all()
.
If you do specify, e.g. related_name=maps
on the User
model, User.map_set
will still work, but the User.maps.
syntax is obviously a bit cleaner and less clunky; so for example, if you had a user object current_user
, you could use current_user.maps.all()
to get all instances of your Map
model that have a relation to current_user
.
The Django documentation has more details.
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")";' />
Very simple to fix, you just need to turn the parameter to writerow into a list.
for item in RESULTS:
wr.writerow([item,])
The quick and dirty way to check what string you need it to look at the generated .resources files.
Your .resources are generated in the resources projects obj/Debug directory. (if not right click on .resx file in solution explorer and hit 'Run Custom Tool' to generate the .resources files)
Navigate to this directory and have a look at the filenames. You should see a file ending in XYZ.resources. Copy that filename and remove the trailing .resources and that is the file you should be loading.
For example in my obj/Bin directory I have the file:
MyLocalisation.Properties.Resources.resources
If the resource files are in the same Class library/Application I would use the following C#
ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", Assembly.GetExecutingAssembly());
However, as it sounds like you are using the resources file from a separate Class library/Application you probably want
Assembly localisationAssembly = Assembly.Load("MyLocalisation");
ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", localisationAssembly);
As of 2018-04-20 Git for Windows has a bug which effectively limits the file size to 4GB max using that particular implementation (this bug propagates to lfs as well).
I also don't like using a function to handle a property which has been resolved again and again in every controller and service. Seem I'm not alone :D
Don't tried to get result with a promise as a variable, of course no way. But I found and use a solution below to access to the result as a property.
Firstly, write result to a property of your service:
app.factory('your_factory',function(){
var theParentIdResult = null;
var factoryReturn = {
theParentId: theParentIdResult,
addSiteParentId : addSiteParentId
};
return factoryReturn;
function addSiteParentId(nodeId) {
var theParentId = 'a';
var parentId = relationsManagerResource.GetParentId(nodeId)
.then(function(response){
factoryReturn.theParentIdResult = response.data;
console.log(theParentId); // #1
});
}
})
Now, we just need to ensure that method addSiteParentId
always be resolved before we accessed to property theParentId
. We can achieve this by using some ways.
Use resolve in router method:
resolve: {
parentId: function (your_factory) {
your_factory.addSiteParentId();
}
}
then in controller and other services used in your router, just call your_factory.theParentId to get your property. Referce here for more information: http://odetocode.com/blogs/scott/archive/2014/05/20/using-resolve-in-angularjs-routes.aspx
Use run
method of app to resolve your service.
app.run(function (your_factory) { your_factory.addSiteParentId(); })
Inject it in the first controller or services of the controller. In the controller we can call all required init services. Then all remain controllers as children of main controller can be accessed to this property normally as you want.
Chose your ways depend on your context depend on scope of your variable and reading frequency of your variable.
Can't you just separate them by a semicolon?
Delete from messages where messageid = '1';
Delete from usersmessages where messageid = '1'
OR
Just use INNER JOIN
as below
DELETE messages , usersmessages FROM messages INNER JOIN usersmessages
WHERE messages.messageid= usersmessages.messageid and messages.messageid = '1'
Using pygame, you can open a window, get the surface as an array of pixels, and manipulate as you want from there. You'll need to copy your numpy array into the surface array, however, which will be much slower than doing actual graphics operations on the pygame surfaces themselves.
In the pop up
You end up with a big line. Then
In the pop up
So you end up with lines that end by dot
And if you have to do the same process lots of times
Object.assign()
Object.assign(dest, src1, src2, ...) merges objects.
It overwrites dest
with properties and values of (however many) source objects, then returns dest
.
The
Object.assign()
method is used to copy the values of all enumerable own properties from one or more source objects to a target object. It will return the target object.
var obj = {key1: "value1", key2: "value2"};
Object.assign(obj, {key3: "value3"});
document.body.innerHTML = JSON.stringify(obj);
_x000D_
{...}
obj = {...obj, ...pair};
From MDN:
It copies own enumerable properties from a provided object onto a new object.
Shallow-cloning (excluding prototype) or merging of objects is now possible using a shorter syntax than
Object.assign()
.Note that
Object.assign()
triggers setters whereas spread syntax doesn’t.
It works in current Chrome and current Firefox. They say it doesn’t work in current Edge.
var obj = {key1: "value1", key2: "value2"};
var pair = {key3: "value3"};
obj = {...obj, ...pair};
document.body.innerHTML = JSON.stringify(obj);
_x000D_
Object assignment operator +=
:
obj += {key3: "value3"};

Above shubham soni answer works for me,actually it happens to android version >=5.0.In above you able to install just use this while creating your apk...
Try using COUNT function like this
=IF(COUNT(SEARCH({"Romney","Obama","Gingrich"},C1)),1,"")
Note that you don't need the wildcards (as teylyn says) and unless there's a specific reason "1" doesn't need quotes (in fact that makes it a text value)
The first <img />
is invalid - src
is a required attribute. data-src
is an attribute than can be leveraged by, say, JavaScript, but has no presentational meaning.
In the future (perhaps) you will be able to use :nth-child(an+b of s)
Actually, browser support for the “of” filter is very limited. Only Safari seems to support the syntax.
Your error shows you are not compiling file with the definition of the insert
function. Update your command to include the file which contains the definition of that function and it should work.
min() fuction exlude BOOLEAN and STRING values. if you replace your zeroes with "" (empty string) - min() function will do its job as you like!
Type type = typeof(MessageProcessor<>).MakeGenericType(key);
That's the best you can do, however without actually knowing what type it is, there's really not much more you can do with it.
EDIT: I should clarify. I changed from var type to Type type. My point is, now you can do something like this:
object obj = Activator.CreateInstance(type);
obj will now be the correct type, but since you don't know what type "key" is at compile time, there's no way to cast it and do anything useful with it.
We can use input data to pass it as a parameter in the HTML file w use ng-model to bind the value of input field.
<input type="text" placeholder="Enter your Email" ng-model="email" required>
<input type="text" placeholder="Enter your password " ng-model="password" required>
and in the js file w use $scope to access this data:
$scope.email="";
$scope.password="";
Controller function will be something like that:
var app = angular.module('myApp', []);
app.controller('assignController', function($scope, $http) {
$scope.email="";
$scope.password="";
$http({
method: "POST",
url: "http://localhost:3000/users/sign_in",
params: {email: $scope.email, password: $scope.password}
}).then(function mySuccess(response) {
// a string, or an object, carrying the response from the server.
$scope.myRes = response.data;
$scope.statuscode = response.status;
}, function myError(response) {
$scope.myRes = response.statusText;
});
});
This is an old question, but I found that when you create a string like this:
<string name="newline_test">My
New line test</string>
The output in your app will be like this (no newline)
My New line test
When you put the string in quotation marks
<string name="newline_test">"My
New line test"</string>
the newline will appear:
My
New line test

I've been struggling with this all afternoon whilst working with an ASP Core project and xUnit 2.2.0. The solution for me was adding a reference to Microsoft.DotNet.InternalAbstractions
I found this out when trying to run the test project manually with dotnet test
which failed but reported that InternalAbstractions
was missing. I did not see this error in the test output window when the auto discovery failed. The only info I saw in the discovery window was a return code, which didn't mean anything to me at the time, but in hindsight was probably indicating an error.
I have a data set with Time as the x-axis, and Intensity as y-axis. I'd need to first delete all the default axes except the axes' labels with:
plot(Time,Intensity,axes=F)
Then I rebuild the plot's elements with:
box() # create a wrap around the points plotted
axis(labels=NA,side=1,tck=-0.015,at=c(seq(from=0,to=1000,by=100))) # labels = NA prevents the creation of the numbers and tick marks, tck is how long the tick mark is.
axis(labels=NA,side=2,tck=-0.015)
axis(lwd=0,side=1,line=-0.4,at=c(seq(from=0,to=1000,by=100))) # lwd option sets the tick mark to 0 length because tck already takes care of the mark
axis(lwd=0,line=-0.4,side=2,las=1) # las changes the direction of the number labels to horizontal instead of vertical.
So, at = c(...)
specifies the collection of positions to put the tick marks. Here I'd like to put the marks at 0, 100, 200,..., 1000. seq(from =...,to =...,by =...)
gives me the choice of limits and the increments.
I know this is a total hack but thought I should add this sample open source audio library I put on github awhile ago...
https://github.com/run-time/jThump
After clicking the link below, type on the home row keys to play a blues riff (also type multiple keys at the same time etc.)
Sample using jThump library >> http://davealger.com/apps/jthump/
It basically works by making invisible <iframe>
elements that load a page that plays a sound onReady().
This is certainly not ideal but you could +1 this solution based on creativity alone (and the fact that it is open source and works in any browser that I've tried it on) I hope this gives someone else searching some ideas at least.
:)
I have some additions to above mentioned answers Its infact a hack mentioned by Jesse Wilson from okhttp, square here. According to this hack, i had to rename my SSLSocketFactory variable to
private SSLSocketFactory delegate;
This is my TLSSocketFactory class
public class TLSSocketFactory extends SSLSocketFactory {
private SSLSocketFactory delegate;
public TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
delegate = context.getSocketFactory();
}
@Override
public String[] getDefaultCipherSuites() {
return delegate.getDefaultCipherSuites();
}
@Override
public String[] getSupportedCipherSuites() {
return delegate.getSupportedCipherSuites();
}
@Override
public Socket createSocket() throws IOException {
return enableTLSOnSocket(delegate.createSocket());
}
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
return enableTLSOnSocket(delegate.createSocket(s, host, port, autoClose));
}
@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
return enableTLSOnSocket(delegate.createSocket(host, port));
}
@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
return enableTLSOnSocket(delegate.createSocket(host, port, localHost, localPort));
}
@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
return enableTLSOnSocket(delegate.createSocket(host, port));
}
@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
return enableTLSOnSocket(delegate.createSocket(address, port, localAddress, localPort));
}
private Socket enableTLSOnSocket(Socket socket) {
if(socket != null && (socket instanceof SSLSocket)) {
((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
}
return socket;
}
}
and this is how i used it with okhttp and retrofit
OkHttpClient client=new OkHttpClient();
try {
client = new OkHttpClient.Builder()
.sslSocketFactory(new TLSSocketFactory())
.build();
} catch (KeyManagementException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.build();
This is what worked for me:
brew update
brew install openssl
ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/
ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/
ln -s /usr/local/Cellar/openssl/1.0.2j/bin/openssl /usr/local/bin/openssl
Thanks to @dorlandode on this thread https://github.com/Homebrew/brew/pull/597
NB: I only used this as a temporary fix until I could spend time correctly installing Openssl again from scratch. As I remember I spent best part of a day debugging and having issues before I realised the best way was to manually install the certs I needed one by one. Please read the link in @bouke's comment before attempting this.
Give this a shot...
public delegate bool TryParseDelegate<T>(string data, out T output);
public static T? ToNullablePrimitive<T>(this string data,
TryParseDelegate<T> func) where T:struct
{
string.IsNullOrEmpty(data) return null;
T output;
if (func(data, out output))
{
return (T?)output;
}
return null;
}
Then call it like this...
void doStuff()
{
string foo = "1.0";
double? myDouble = foo.ToNullablePrimitive<double>(double.TryParse);
foo = "1";
int? myInt = foo.ToNullablePrimitive<int>(int.TryParse);
foo = "haha";
int? myInt2 = foo.ToNullablePrimitive<int>(int.TryParse);
}
Remove padding between cells inside the table. Just use cellpadding=0
and cellspacing=0
attributes in table tag.
One other work-around is to use jupyter notebooks and use the markdown mode in cells to render equations.
Basic stuff seems to work perfectly, like centered equations
\begin{equation}
...
\end{equation}
or inline equations
$ \sum_{\forall i}{x_i^{2}} $
Although, one of the functions that I really wanted did not render at all in github was \mbox{}
, which was a bummer. But, all in all this has been the most successful way of rendering equations on github.
UPDATE:
In scikit-learn 0.22, there's a new feature to plot the confusion matrix directly.
See the documentation: sklearn.metrics.plot_confusion_matrix
OLD ANSWER:
I think it's worth mentioning the use of seaborn.heatmap
here.
import seaborn as sns
import matplotlib.pyplot as plt
ax= plt.subplot()
sns.heatmap(cm, annot=True, ax = ax); #annot=True to annotate cells
# labels, title and ticks
ax.set_xlabel('Predicted labels');ax.set_ylabel('True labels');
ax.set_title('Confusion Matrix');
ax.xaxis.set_ticklabels(['business', 'health']); ax.yaxis.set_ticklabels(['health', 'business']);
One of the weird behaviour and spec in Javascript is the typeof Array is Object
.
You can check if the variable is an array in couple of ways:
var isArr = data instanceof Array;
var isArr = Array.isArray(data);
But the most reliable way is:
isArr = Object.prototype.toString.call(data) == '[object Array]';
Since you tagged your question with jQuery, you can use jQuery isArray
function:
var isArr = $.isArray(data);
Simple problem actually. Change:
if (strTemp != '')
to
if ($strTemp != '')
Arguably you may also want to change it to:
if ($strTemp !== '')
since != ''
will return true if you pass is numeric 0 and a few other cases due to PHP's automatic type conversion.
You should not use the built-in empty() function for this; see comments and the PHP type comparison tables.
You can use axes.set_prop_cycle
(example).
You can use axes.set_color_cycle
(example).
You can use Axes.set_default_color_cycle
.
So I used the overflowing jquery library: https://github.com/kevinmarx/overflowing
After installing the library, if you want to assign the class overflowing
to all overflowing elements, you simply run:
$('.targetElement').overflowing('.parentElement')
This will then give the class overflowing
, as in <div class="targetElement overflowing">
to all elements that are overflowing. You could then add this to some event handler(click, mouseover) or other function that will run the above code so that it updates dynamically.
WORKING Method { if there is no problem other than configuration }
By Default Appache is not restricting access from ipv4. (common external ip)
What may restrict is the configurations in 'httpd.conf' (or 'apache2.conf' depending on your apache configuration)
Solution:
Replace all:
<Directory />
AllowOverride none
Require all denied
</Directory>
with
<Directory />
AllowOverride none
# Require all denied
</Directory>
hence removing out all restriction given to Apache
Replace Require local
with Require all granted
at C:/wamp/www/
directory
<Directory "c:/wamp/www/">
Options Indexes FollowSymLinks
AllowOverride all
Require all granted
# Require local
</Directory>

I try it it works on WPF
You could use a label (see JsFiddle)
CSS
label { display: inline-block; width: 210px; text-align: right; }
HTML
<html>
<label for="name">Name:</label><input id="name" type="text"><br />
<label for="email">Email Address:</label><input id="email" type="text"><br />
<label for="desc">Description of the input value:</label><input id="desc" type="text"><br />
</html>
Or you could use those labels in a table (JsFiddle)
<html>
<table>
<tbody>
<tr><td><label for="name">Name:</label></td><td><input id="name" type="text"></td></tr>
<tr><td><label for="email">Email Address:</label></td><td><input id="email" type = "text"></td></tr>
<tr><td><label for="desc">Description of the input value:</label></td><td><input id="desc" type="text"></td></tr>
</tbody>
</table>

From Save MySQL query results into a text or CSV file:
MySQL provides an easy mechanism for writing the results of a select statement into a text file on the server. Using extended options of the INTO OUTFILE nomenclature, it is possible to create a comma separated value (CSV) which can be imported into a spreadsheet application such as OpenOffice or Excel or any other application which accepts data in CSV format.
Given a query such as
SELECT order_id,product_name,qty FROM orders
which returns three columns of data, the results can be placed into the file /tmp/orders.txt using the query:
SELECT order_id,product_name,qty FROM orders INTO OUTFILE '/tmp/orders.txt'
This will create a tab-separated file, each row on its own line. To alter this behavior, it is possible to add modifiers to the query:
SELECT order_id,product_name,qty FROM orders INTO OUTFILE '/tmp/orders.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n'
In this example, each field will be enclosed in double quotes, the fields will be separated by commas, and each row will be output on a new line separated by a newline (\n). Sample output of this command would look like:
"1","Tech-Recipes sock puppet","14.95" "2","Tech-Recipes chef's hat","18.95"
Keep in mind that the output file must not already exist and that the user MySQL is running as has write permissions to the directory MySQL is attempting to write the file to.
Syntax
SELECT Your_Column_Name
FROM Your_Table_Name
INTO OUTFILE 'Filename.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
Or you could try to grab the output via the client:
You could try executing the query from the your local client and redirect the output to a local file destination:
mysql -user -pass -e "select cols from table where cols not null" > /tmp/output
Hint: If you don't specify an absoulte path but use something like INTO OUTFILE 'output.csv'
or INTO OUTFILE './output.csv'
, it will store the output file to the directory specified by show variables like 'datadir';
.
If all you need is the stdout
output, then take a look at subprocess.check_output()
:
import subprocess
batcmd="dir"
result = subprocess.check_output(batcmd, shell=True)
Because you were using os.system()
, you'd have to set shell=True
to get the same behaviour. You do want to heed the security concerns about passing untrusted arguments to your shell.
If you need to capture stderr
as well, simply add stderr=subprocess.STDOUT
to the call:
result = subprocess.check_output([batcmd], stderr=subprocess.STDOUT)
to redirect the error output to the default output stream.
If you know that the output is text, add text=True
to decode the returned bytes value with the platform default encoding; use encoding="..."
instead if that codec is not correct for the data you receive.
Another similar option that I think Nick briefly alluded to in the comments is to create multiple wrapper jars. I haven't tried it, but I think they could be completely empty other than the manifest file, which should specify the main class to load as well as the inclusion of the MyJar.jar to the classpath.
MyJar1.jar\META-INF\MANIFEST.MF
Manifest-Version: 1.0
Main-Class: com.mycomp.myproj.dir1.MainClass1
Class-Path: MyJar.jar
MyJar2.jar\META-INF\MANIFEST.MF
Manifest-Version: 1.0
Main-Class: com.mycomp.myproj.dir2.MainClass2
Class-Path: MyJar.jar
etc.
Then just run it with java -jar MyJar2.jar
"Any" works well. Just make sure that the any keyword is on the right side of the equal to sign i.e. is present after the equal to sign.
Below statement will throw error: ERROR: syntax error at or near "any"
select 1 where any('{hello}'::text[]) = 'hello';
Whereas below example works fine
select 1 where 'hello' = any('{hello}'::text[]);
Try this
products.sort(function (a, b) {
return a.title.rendered - b.title.rendered;
});
OR
You can import lodash/underscore library, it has many build functions available for manipulating, filtering, sorting the array and all.
Using underscore: (below one is just an example)
import * as _ from 'underscore';
let sortedArray = _.sortBy(array, 'title');
I've done this several different ways but the only way I've found that keeps the labels and corresponding text/input data on the same line and always wraps perfectly to the width of the parent is to use display:inline table.
CSS
.container {
display: inline-table;
padding-right: 14px;
margin-top:5px;
margin-bottom:5px;
}
.fieldName {
display: table-cell;
vertical-align: middle;
padding-right: 4px;
}
.data {
display: table-cell;
}
HTML
<div class='container'>
<div class='fieldName'>
<label>Student</label>
</div>
<div class='data'>
<input name="Student" />
</div>
</div>
<div class='container'>
<div class='fieldName'>
<label>Email</label>
</div>
<div class='data'>
<input name="Email" />
</div>
</div>
With *nix, usually, you don't need a software to view an .img file. You can use the loop device to mount it and then every file manager to navigate it. Here you can find how. Sometime you need to install some package to manage strange filesystem like squashfs.
it work in my case, oldSensor and newSnsor - oldView and newView:
private void replaceSensors(View oldSensor, View newSensor) {
ViewGroup parent = (ViewGroup) oldSensor.getParent();
if (parent == null) {
return;
}
int indexOldSensor = parent.indexOfChild(oldSensor);
int indexNewSensor = parent.indexOfChild(newSensor);
parent.removeView(oldSensor);
parent.addView(oldSensor, indexNewSensor);
parent.removeView(newSensor);
parent.addView(newSensor, indexOldSensor);
}
Beside the fact, that push_back(x)
does the same as insert(x, end())
(maybe with slightly better performance), there are several important thing to know about these functions:
push_back
exists only on BackInsertionSequence
containers - so, for example, it doesn't exist on set
. It couldn't because push_back()
grants you that it will always add at the end.FrontInsertionSequence
and they have push_front
. This is satisfied by deque
, but not by vector
.insert(x, ITERATOR)
is from InsertionSequence
, which is common for set
and vector
. This way you can use either set
or vector
as a target for multiple insertions. However, set
has additionally insert(x)
, which does practically the same thing (this first insert in set
means only to speed up searching for appropriate place by starting from a different iterator - a feature not used in this case).Note about the last case that if you are going to add elements in the loop, then doing container.push_back(x)
and container.insert(x, container.end())
will do effectively the same thing. However this won't be true if you get this container.end()
first and then use it in the whole loop.
For example, you could risk the following code:
auto pe = v.end();
for (auto& s: a)
v.insert(pe, v);
This will effectively copy whole a
into v
vector, in reverse order, and only if you are lucky enough to not get the vector reallocated for extension (you can prevent this by calling reserve()
first); if you are not so lucky, you'll get so-called UndefinedBehavior(tm). Theoretically this isn't allowed because vector's iterators are considered invalidated every time a new element is added.
If you do it this way:
copy(a.begin(), a.end(), back_inserter(v);
it will copy a
at the end of v
in the original order, and this doesn't carry a risk of iterator invalidation.
[EDIT] I made previously this code look this way, and it was a mistake because inserter
actually maintains the validity and advancement of the iterator:
copy(a.begin(), a.end(), inserter(v, v.end());
So this code will also add all elements in the original order without any risk.
MongoDB 3.2 now allows one to combine data from multiple collections into one through the $lookup aggregation stage. As a practical example, lets say that you have data about books split into two different collections.
First collection, called books
, having the following data:
{
"isbn": "978-3-16-148410-0",
"title": "Some cool book",
"author": "John Doe"
}
{
"isbn": "978-3-16-148999-9",
"title": "Another awesome book",
"author": "Jane Roe"
}
And the second collection, called books_selling_data
, having the following data:
{
"_id": ObjectId("56e31bcf76cdf52e541d9d26"),
"isbn": "978-3-16-148410-0",
"copies_sold": 12500
}
{
"_id": ObjectId("56e31ce076cdf52e541d9d28"),
"isbn": "978-3-16-148999-9",
"copies_sold": 720050
}
{
"_id": ObjectId("56e31ce076cdf52e541d9d29"),
"isbn": "978-3-16-148999-9",
"copies_sold": 1000
}
To merge both collections is just a matter of using $lookup in the following way:
db.books.aggregate([{
$lookup: {
from: "books_selling_data",
localField: "isbn",
foreignField: "isbn",
as: "copies_sold"
}
}])
After this aggregation, the books
collection will look like the following:
{
"isbn": "978-3-16-148410-0",
"title": "Some cool book",
"author": "John Doe",
"copies_sold": [
{
"_id": ObjectId("56e31bcf76cdf52e541d9d26"),
"isbn": "978-3-16-148410-0",
"copies_sold": 12500
}
]
}
{
"isbn": "978-3-16-148999-9",
"title": "Another awesome book",
"author": "Jane Roe",
"copies_sold": [
{
"_id": ObjectId("56e31ce076cdf52e541d9d28"),
"isbn": "978-3-16-148999-9",
"copies_sold": 720050
},
{
"_id": ObjectId("56e31ce076cdf52e541d9d28"),
"isbn": "978-3-16-148999-9",
"copies_sold": 1000
}
]
}
It is important to note a few things:
books_selling_data
, cannot be sharded.So, as a conclusion, if you want to consolidate both collections, having, in this case, a flat copies_sold field with the total copies sold, you will have to work a little bit more, probably using an intermediary collection that will, then, be $out to the final collection.
how can i return a array in a c++ method and how must i declare it? int[] test(void); ??
This sounds like a simple question, but in C++ you have quite a few options. Firstly, you should prefer...
std::vector<>
, which grows dynamically to however many elements you encounter at runtime, or
std::array<>
(introduced with C++11), which always stores a number of elements specified at compile time,
...as they manage memory for you, ensuring correct behaviour and simplifying things considerably:
std::vector<int> fn()
{
std::vector<int> x;
x.push_back(10);
return x;
}
std::array<int, 2> fn2() // C++11
{
return {3, 4};
}
void caller()
{
std::vector<int> a = fn();
const std::vector<int>& b = fn(); // extend lifetime but read-only
// b valid until scope exit/return
std::array<int, 2> c = fn2();
const std::array<int, 2>& d = fn2();
}
The practice of creating a const
reference to the returned data can sometimes avoid a copy, but normally you can just rely on Return Value Optimisation, or - for vector
but not array
- move semantics (introduced with C++11).
If you really want to use an inbuilt array (as distinct from the Standard library class called array
mentioned above), one way is for the caller to reserve space and tell the function to use it:
void fn(int x[], int n)
{
for (int i = 0; i < n; ++i)
x[i] = n;
}
void caller()
{
// local space on the stack - destroyed when caller() returns
int x[10];
fn(x, sizeof x / sizeof x[0]);
// or, use the heap, lives until delete[](p) called...
int* p = new int[10];
fn(p, 10);
}
Another option is to wrap the array in a structure, which - unlike raw arrays - are legal to return by value from a function:
struct X
{
int x[10];
};
X fn()
{
X x;
x.x[0] = 10;
// ...
return x;
}
void caller()
{
X x = fn();
}
Starting with the above, if you're stuck using C++03 you might want to generalise it into something closer to the C++11 std::array
:
template <typename T, size_t N>
struct array
{
T& operator[](size_t n) { return x[n]; }
const T& operator[](size_t n) const { return x[n]; }
size_t size() const { return N; }
// iterators, constructors etc....
private:
T x[N];
};
Another option is to have the called function allocate memory on the heap:
int* fn()
{
int* p = new int[2];
p[0] = 0;
p[1] = 1;
return p;
}
void caller()
{
int* p = fn();
// use p...
delete[] p;
}
To help simplify the management of heap objects, many C++ programmers use "smart pointers" that ensure deletion when the pointer(s) to the object leave their scopes. With C++11:
std::shared_ptr<int> p(new int[2], [](int* p) { delete[] p; } );
std::unique_ptr<int[]> p(new int[3]);
If you're stuck on C++03, the best option is to see if the boost library is available on your machine: it provides boost::shared_array
.
Yet another option is to have some static memory reserved by fn()
, though this is NOT THREAD SAFE, and means each call to fn()
overwrites the data seen by anyone keeping pointers from previous calls. That said, it can be convenient (and fast) for simple single-threaded code.
int* fn(int n)
{
static int x[2]; // clobbered by each call to fn()
x[0] = n;
x[1] = n + 1;
return x; // every call to fn() returns a pointer to the same static x memory
}
void caller()
{
int* p = fn(3);
// use p, hoping no other thread calls fn() meanwhile and clobbers the values...
// no clean up necessary...
}
In my case, I deleted one file directly from team explorer git menu which was causing this problem. When I checked solution explorer it was still showing the deleted file as unreferenced file. When I removed that file from solution explorer, I was able to build project successfully.
It's a shame that we need multiple ARG too, it results in multiple layers and slows down the build because of that, and for anyone also wondering that, currently there is no way to set multiple ARGs.
With abstract classes you can have some kind of skeleton for other classes to extend.
You can't instantiate them but you can put some common implementation which you can use in the classes that extend them.
You are not passing the variable correctly. One fast solution is to make a global variable like this:
var global_json_data;
$(document).ready(function() {
var json_source = "https://spreadsheets.google.com/feeds/list/0ApL1zT2P00q5dG1wOUMzSlNVV3VRV2pwQ2Fnbmt3M0E/od7/public/basic?alt=json";
var string_data ="";
var json_data = $.ajax({
dataType: 'json', // Return JSON
url: json_source,
success: function(data){
var data_obj = [];
for (i=0; i<data.feed.entry.length; i++){
var el = {'key': data.feed.entry[i].title['$t'], 'value': '<p><a href="'+data.feed.entry[i].content['$t']+'>'+data.feed.entry[i].title['$t']+'</a></p>'};
data_obj.push(el)};
console.log("data grabbed");
global_json_data = data_obj;
return data_obj;
},
error: function(jqXHR, textStatus, errorThrown){
$('#results_box').html('<h2>Something went wrong!</h2><p><b>' + textStatus + '</b> ' + errorThrown + '</p>');
}
});
$(':submit').click(function(event){
var json_data = global_json_data;
event.preventDefault();
console.log(json_data.length);
//function
if ($('#place').val() !=''){
var copy_string = $('#place').val();
var converted_string = copy_string;
for (i=0; i<json_data.length; i++){
//console_log(data.feed.entry[i].title['$t']);
converted_string = converted_string.replace(json_data.feed.entry[i].title['$t'],
'<a href="'+json_data.feed.entry[i].content['$t']+'>'+json_data.feed.entry[i].title['$t']+'</a>');
}
$('#results_box').text(converted_string).html();
}
});
});//document ready end
If all else fails just go to your terminal and type from your folder:
git push origin master
That's the way the Gods originally wanted it to be.
I know it's an old question, but I believe still valid even in 2018.
There is an option to Take a bug report hidden in Developer options in every android device.
NOTE: This would dump whole system log
How to enable developer options? see: https://developer.android.com/studio/debug/dev-options
What works for me:
how to read this? open bugreport-1960-01-01-hh-mm-ss.txt
you probably want to look for something like this:
------ SYSTEM LOG (logcat -v threadtime -v printable -d *:v) ------
--------- beginning of crash
06-13 14:37:36.542 19294 19294 E AndroidRuntime: FATAL EXCEPTION: main
or:
------ SYSTEM LOG (logcat -v threadtime -v printable -d *:v) ------
--------- beginning of main
I think your asking to select only <span class = "my_class">hello</span>
this element, You have do like this, If I am understand your question correctly this is the answer,
$("#my_id [class='my_class']").addClass('test');
For the first case you propose you can use: '[[:blank:]]+[A-Z0-9]+[[:blank:]]+', for example:
echo "The thing P1 must connect to the J236 thing in the Foo position" | grep -oE '[[:blank:]]+[A-Z0-9]+[[:blank:]]+'
In the second case maybe you need to use something else and not a regex, maybe a script with a dictionary of technical words...
Cheers, Fernando
The way you have used the HTML syntax is problematic.
This is how the syntax should be
style="property1:value1;property2:value2"
In your case, this will be the way to do
<h2 style="text-align :center; font-family :tahoma" >TITLE</h2>
A further example would be as follows
<div class ="row">
<button type="button" style= "margin-top : 20px; border-radius: 15px"
class="btn btn-primary">View Full Profile</button>
</div>
You need to use to_timestamp()
to convert your string to a proper timestamp
value:
to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
If your column is of type DATE
(which also supports seconds), you need to use to_date()
to_date('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
To get this into a where
condition use the following:
select *
from TableA
where startdate >= to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
and startdate <= to_timestamp('12-01-2012 21:25:33', 'dd-mm-yyyy hh24:mi:ss')
You never need to use to_timestamp()
on a column that is of type timestamp
.
If you don't need a human-readable output, another option you could try is to save the array as a MATLAB .mat
file, which is a structured array. I despise MATLAB, but the fact that I can both read and write a .mat
in very few lines is convenient.
Unlike Joe Kington's answer, the benefit of this is that you don't need to know the original shape of the data in the .mat
file, i.e. no need to reshape upon reading in. And, unlike using pickle
, a .mat
file can be read by MATLAB, and probably some other programs/languages as well.
Here is an example:
import numpy as np
import scipy.io
# Some test data
x = np.arange(200).reshape((4,5,10))
# Specify the filename of the .mat file
matfile = 'test_mat.mat'
# Write the array to the mat file. For this to work, the array must be the value
# corresponding to a key name of your choice in a dictionary
scipy.io.savemat(matfile, mdict={'out': x}, oned_as='row')
# For the above line, I specified the kwarg oned_as since python (2.7 with
# numpy 1.6.1) throws a FutureWarning. Here, this isn't really necessary
# since oned_as is a kwarg for dealing with 1-D arrays.
# Now load in the data from the .mat that was just saved
matdata = scipy.io.loadmat(matfile)
# And just to check if the data is the same:
assert np.all(x == matdata['out'])
If you forget the key that the array is named in the .mat
file, you can always do:
print matdata.keys()
And of course you can store many arrays using many more keys.
So yes – it won't be readable with your eyes, but only takes 2 lines to write and read the data, which I think is a fair trade-off.
Take a look at the docs for scipy.io.savemat and scipy.io.loadmat and also this tutorial page: scipy.io File IO Tutorial
Whatever urllib is using to figure out Content-Length seems to get confused by json, so you have to calculate that yourself.
import json
import urllib2
data = json.dumps([1, 2, 3])
clen = len(data)
req = urllib2.Request(url, data, {'Content-Type': 'application/json', 'Content-Length': clen})
f = urllib2.urlopen(req)
response = f.read()
f.close()
Took me for ever to figure this out, so I hope it helps someone else.
First check the logs why the container failed. Because your restart policy might bring your container back to running status. Better to fix the issue, Then probably you can build a new image with/without fix. Later execute below command
docker system prune
https://forums.docker.com/t/docker-registry-in-restarting-1-status-forever/12717/3
In short:
defaultdict(int)
- the argument int indicates that the values will be int type.
defaultdict(list)
- the argument list indicates that the values will be list type.
I like the Aptana Browser Preview windo for this.
You can get it from their update site: http://download.aptana.org/tools/studio/plugin/update/studio/
After you install the Aptana plugin, open an Aptana project and there should be an option under help to install aptana features. under other you will find a Firefox/XUL browser. There may be a more direct way to install the XUL plugin, but the above procedure works.
I have read all answers and I want to summarize for better understanding at first glance like following:
Firstly, the whole command that gets executed in the container includes two parts: the command and the arguments
ENTRYPOINT defines the executable invoked when the container is started (for command)
CMD specifies the arguments that get passed to the ENTRYPOINT (for arguments)
In the Kubernetes In Action book points an important note about it. (chapter 7)
Although you can use the CMD instruction to specify the command you want to execute when the image is run, the correct way is to do it through the ENTRYPOINT instruction and to only specify the CMD if you want to define the default arguments.
You can also read this article for great explanation in a simple way
unsigned char bits = sizeof(X) << 3;
where X
is a char
,int
,long
etc.. will give you size of X
in bits.
You can use a $where. Just be aware it will be fairly slow (has to execute Javascript code on every record) so combine with indexed queries if you can.
db.T.find( { $where: function() { return this.Grade1 > this.Grade2 } } );
or more compact:
db.T.find( { $where : "this.Grade1 > this.Grade2" } );
you can use $expr
as described in recent answer
You have more going on than you said. I ran the following expanded test from your example:
public class test {
public static void main(String[] args) {
Object[][] someArray = new Object[5][];
someArray[0] = new Object[10];
someArray[1] = null;
someArray[2] = new Object[1];
someArray[3] = null;
someArray[4] = new Object[5];
for (int i=0; i<=someArray.length-1; i++) {
if (someArray[i] != null) {
System.out.println("not null");
} else {
System.out.println("null");
}
}
}
}
and got the expected output:
$ /cygdrive/c/Program\ Files/Java/jdk1.6.0_03/bin/java -cp . test
not null
null
not null
null
not null
Are you possibly trying to check the lengths of someArray[index]?
You already have a process bound to the default port (8000). If you already ran the same module before, it is most likely that process still bound to the port. Try and locate the other process first:
$ ps -fA | grep python
501 81651 12648 0 9:53PM ttys000 0:00.16 python -m SimpleHTTPServer
The command arguments are included, so you can spot the one running SimpleHTTPServer
if more than one python
process is active. You may want to test if http://localhost:8000/
still shows a directory listing for local files.
The second number is the process number; stop the server by sending it a signal:
kill 81651
This sends a standard SIGTERM
signal; if the process is unresponsive you may have to resort to tougher methods like sending a SIGKILL
(kill -s KILL <pid>
or kill -9 <pid>
) signal instead. See Wikipedia for more details.
Alternatively, run the server on a different port, by specifying the alternative port on the command line:
$ python -m SimpleHTTPServer 8910
Serving HTTP on 0.0.0.0 port 8910 ...
then access the server as http://localhost:8910
; where 8910
can be any number from 1024 and up, provided the port is not already taken.
Why do we need to differentiate between POD's and non-POD's at all?
C++ started its life as an extension of C. While modern C++ is no longer a strict superset of C, people still expect a high level of compatibility between the two. The "C ABI" of a platform also frequently acts as a de-facto standard inter-language ABI for other languages on the platform.
Roughly speaking, a POD type is a type that is compatible with C and perhaps equally importantly is compatible with certain ABI optimisations.
To be compatible with C, we need to satisfy two constraints.
Certain C++ features are incompatible with this.
Virtual methods require the compiler to insert one or more pointers to virtual method tables, something that doesn't exist in C.
User-defined copy constructors, move constructors, copy assignments and destructors have implications for parameter passing and returning. Many C ABIs pass and return small parameters in registers, but the references passed to the user defined constructor/assigment/destructor can only work with memory locations.
So there is a need to define what types can be expected to be "C compatible" and what types cannot. C++03 was somewhat over-strict in this regard, any user-defined constructor would disable the built-in constructors and any attempt to add them back in would result in them being user-defined and hence the type being non-pod. C++11 opened things up quite a bit, by allowing the user to re-introduce the built-in constructors.
change your html to the following:
<ul>
<li onclick="myfunction()">
<span></span>
<p id="myParagraph">This Text</p>
</li>
</ul>
then you can get the content of your paragraph with the following function:
function getContent() {
return document.getElementById("myParagraph").innerHTML;
}
If you are using Angular 6 /7
import { of } from 'rxjs';
And then instead of calling
Observable.of(res);
just use
of(res);
I would recommend using jQuery with this function:
$(document).ready(function(){
$('#about').addClass('expand');
});
This will add the expand class to an element with id of about when the dom is ready on page load.
set<T> s;
//....
vector<T> v;
v.assign(s.begin(), s.end());
This line:
public object Hours { get; set; }}
Your have a redundand }

The usage info:
Usage: brew switch <formula> <version>
Example:
brew switch mysql 5.5.29
You can find the versions installed on your system with info
.
brew info mysql
And to see the available versions to install, you can provide a dud version number, as brew will helpfully respond with the available version numbers:
brew switch mysql 0
Update (15.10.2014):
The brew versions
command has been removed from brew, but, if you do wish to use this command first run brew tap homebrew/boneyard
.
The recommended way to install an old version is to install from the homebrew/versions
repo as follows:
$ brew tap homebrew/versions
$ brew install mysql55
For detailed info on all the ways to install an older version of a formula read this answer.
Firstly, double quote character is nothing special in regex - it's just another character, so it doesn't need escaping from the perspective of regex.
However, because java uses double quotes to delimit String constants, if you want to create a string in java with a double quote in it, you must escape them.
This code will test if your String matches:
if (str.matches("\".*\"")) {
// this string starts and end with a double quote
}
Note that you don't need to add start and end of input markers (^
and $
) in the regex, because matches()
requires that the whole input be matched to return true - ^
and $
are implied.
In my case, 2 Factor Authentication was turned on for the FROM account in Office 365. Once that was turned off, the email sent successfully.
I understand that there is a 4000 max set for
NVARCHAR(MAX)
Your understanding is wrong. nvarchar(max)
can store up to (and beyond sometimes) 2GB of data (1 billion double byte characters).
From nchar and nvarchar in Books online the grammar is
nvarchar [ ( n | max ) ]
The |
character means these are alternatives. i.e. you specify either n
or the literal max
.
If you choose to specify a specific n
then this must be between 1 and 4,000 but using max
defines it as a large object datatype (replacement for ntext
which is deprecated).
In fact in SQL Server 2008 it seems that for a variable the 2GB limit can be exceeded indefinitely subject to sufficient space in tempdb
(Shown here)
Regarding the other parts of your question
varchar(n) + varchar(n)
will truncate at 8,000 characters.nvarchar(n) + nvarchar(n)
will truncate at 4,000 characters.varchar(n) + nvarchar(n)
will truncate at 4,000 characters. nvarchar
has higher precedence so the result is nvarchar(4,000)
[n]varchar(max)
+ [n]varchar(max)
won't truncate (for < 2GB).varchar(max)
+ varchar(n)
won't truncate (for < 2GB) and the result will be typed as varchar(max)
.varchar(max)
+ nvarchar(n)
won't truncate (for < 2GB) and the result will be typed as nvarchar(max)
.nvarchar(max)
+ varchar(n)
will first convert the varchar(n)
input to nvarchar(n)
and then do the concatenation. If the length of the varchar(n)
string is greater than 4,000 characters the cast will be to nvarchar(4000)
and truncation will occur.If you use the N
prefix and the string is <= 4,000 characters long it will be typed as nvarchar(n)
where n
is the length of the string. So N'Foo'
will be treated as nvarchar(3)
for example. If the string is longer than 4,000 characters it will be treated as nvarchar(max)
If you don't use the N
prefix and the string is <= 8,000 characters long it will be typed as varchar(n)
where n
is the length of the string. If longer as varchar(max)
For both of the above if the length of the string is zero then n
is set to 1.
1. The CONCAT
function doesn't help here
DECLARE @A5000 VARCHAR(5000) = REPLICATE('A',5000);
SELECT DATALENGTH(@A5000 + @A5000),
DATALENGTH(CONCAT(@A5000,@A5000));
The above returns 8000 for both methods of concatenation.
2. Be careful with +=
DECLARE @A VARCHAR(MAX) = '';
SET @A+= REPLICATE('A',5000) + REPLICATE('A',5000)
DECLARE @B VARCHAR(MAX) = '';
SET @B = @B + REPLICATE('A',5000) + REPLICATE('A',5000)
SELECT DATALENGTH(@A),
DATALENGTH(@B);`
Returns
-------------------- --------------------
8000 10000
Note that @A
encountered truncation.
You are getting truncation either because you are concatenating two non max
datatypes together or because you are concatenating a varchar(4001 - 8000)
string to an nvarchar
typed string (even nvarchar(max)
).
To avoid the second issue simply make sure that all string literals (or at least those with lengths in the 4001 - 8000 range) are prefaced with N
.
To avoid the first issue change the assignment from
DECLARE @SQL NVARCHAR(MAX);
SET @SQL = 'Foo' + 'Bar' + ...;
To
DECLARE @SQL NVARCHAR(MAX) = '';
SET @SQL = @SQL + N'Foo' + N'Bar'
so that an NVARCHAR(MAX)
is involved in the concatenation from the beginning (as the result of each concatenation will also be NVARCHAR(MAX)
this will propagate)
Make sure you have "results to grid" mode selected then you can use
select @SQL as [processing-instruction(x)] FOR XML PATH
The SSMS options allow you to set unlimited length for XML
results. The processing-instruction
bit avoids issues with characters such as <
showing up as <
.
Enough explanation about each parameter is given by other answers; However you asked for a real world example, here is the one that clarifies the purpose of different propagation options:
Suppose you're in charge of implementing a signup service in which a confirmation e-mail is sent to the user. You come up with two service objects, one for enrolling the user and one for sending e-mails, which the latter is called inside the first one. For example something like this:/* Sign Up service */
@Service
@Transactional(Propagation=REQUIRED)
class SignUpService{
...
void SignUp(User user){
...
emailService.sendMail(User);
}
}
/* E-Mail Service */
@Service
@Transactional(Propagation=REQUIRES_NEW)
class EmailService{
...
void sendMail(User user){
try{
... // Trying to send the e-mail
}catch( Exception)
}
}
You may have noticed that the second service is of propagation type REQUIRES_NEW and moreover chances are it throws an exception (SMTP server down ,invalid e-mail or other reasons).You probably don't want the whole process to roll-back, like removing the user information from database or other things; therefore you call the second service in a separate transaction.
Back to our example, this time you are concerned about the database security, so you define your DAO classes this way:/* User DAO */
@Transactional(Propagation=MANDATORY)
class UserDAO{
// some CRUD methods
}
Meaning that whenever a DAO object, and hence a potential access to db, is created, we need to reassure that the call was made from inside one of our services, implying that a live transaction should exist; otherwise an exception occurs.Therefore the propagation is of type MANDATORY.
What is Angular CLI Budgets? Budgets is one of the less known features of the Angular CLI. It’s a rather small but a very neat feature!
As applications grow in functionality, they also grow in size. Budgets is a feature in the Angular CLI which allows you to set budget thresholds in your configuration to ensure parts of your application stay within boundaries which you set — Official Documentation
Or in other words, we can describe our Angular application as a set of compiled JavaScript files called bundles which are produced by the build process. Angular budgets allows us to configure expected sizes of these bundles. More so, we can configure thresholds for conditions when we want to receive a warning or even fail build with an error if the bundle size gets too out of control!
How To Define A Budget? Angular budgets are defined in the angular.json file. Budgets are defined per project which makes sense because every app in a workspace has different needs.
Thinking pragmatically, it only makes sense to define budgets for the production builds. Prod build creates bundles with “true size” after applying all optimizations like tree-shaking and code minimization.
Oops, a build error! The maximum bundle size was exceeded. This is a great signal that tells us that something went wrong…
First Approach: Are your files gzipped?
Generally speaking, gzipped file has only about 20% the size of the original file, which can drastically decrease the initial load time of your app. To check if you have gzipped your files, just open the network tab of developer console. In the “Response Headers”, if you should see “Content-Encoding: gzip”, you are good to go.
How to gzip? If you host your Angular app in most of the cloud platforms or CDN, you should not worry about this issue as they probably have handled this for you. However, if you have your own server (such as NodeJS + expressJS) serving your Angular app, definitely check if the files are gzipped. The following is an example to gzip your static assets in a NodeJS + expressJS app. You can hardly imagine this dead simple middleware “compression” would reduce your bundle size from 2.21MB to 495.13KB.
const compression = require('compression')
const express = require('express')
const app = express()
app.use(compression())
Second Approach:: Analyze your Angular bundle
If your bundle size does get too big you may want to analyze your bundle because you may have used an inappropriate large-sized third party package or you forgot to remove some package if you are not using it anymore. Webpack has an amazing feature to give us a visual idea of the composition of a webpack bundle.
It’s super easy to get this graph.
npm install -g webpack-bundle-analyzer
ng build --stats-json
(don’t use flag --prod
). By enabling --stats-json
you will get an additional file stats.jsonwebpack-bundle-analyzer ./dist/stats.json
and your browser will pop up the page at localhost:8888. Have fun with it.ref 1: How Did Angular CLI Budgets Save My Day And How They Can Save Yours
I wasn't having codec issues or dimension issues as the answers above. Instead, my issue was because my output frames were in greyscale.
I had to create a VideoWriter with the parameter isColor=False
out = cv2.VideoWriter(output_path,
cv2.VideoWriter_fourcc(*'mp4v'),
30,
(INPUT_VIDEO_WIDTH,INPUT_VIDEO_HEIGHT),
isColor=False
)
In the API Docs, it wrongly says that the flag is currently supported on Windows only. I have tested on Ubuntu 20.04, with opencv-python==4.2.0.34, and it finally writes out to file correctly.
try this:
.test {
position:absolute;
background:blue;
width:200px;
height:200px;
top:40px;
transition:left 1s linear;
left: 0;
}
Given your example, you need to add the following import in your main.main
class:
import second.second;
Some bonus advice, make sure you titlecase your class names as that is a Java standard. So your example Main class will have the structure:
package main; //lowercase package names
public class Main //titlecase class names
{
//Main class content
}
