Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.
In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.
Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.
If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40)
.
If you use pyplot
programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40)
or afterwards with ax.yaxis.label.set_size(40)
.
This defines what shell (command interpreter) you are using for interpreting/running your script. Each shell is slightly different in the way it interacts with the user and executes scripts (programs).
When you type in a command at the Unix prompt, you are interacting with the shell.
E.g., #!/bin/csh
refers to the C-shell, /bin/tcsh
the t-shell, /bin/bash
the bash shell, etc.
You can tell which interactive shell you are using the
echo $SHELL
command, or alternatively
env | grep -i shell
You can change your command shell with the chsh
command.
Each has a slightly different command set and way of assigning variables and its own set of programming constructs. For instance the if-else statement with bash looks different that the one in the C-shell.
This page might be of interest as it "translates" between bash and tcsh commands/syntax.
Using the directive in the shell script allows you to run programs using a different shell. For instance I use the tcsh
shell interactively, but often run bash scripts using /bin/bash in the script file.
Aside:
This concept extends to other scripts too. For instance if you program in Python you'd put
#!/usr/bin/python
at the top of your Python program
There's an easy way to do that. Very easy. Since I noticed that
$scope.yourModel = [];
removes all $scope.yourModel array list you can do like this
function deleteAnObjectByKey(objects, key) {
var clonedObjects = Object.assign({}, objects);
for (var x in clonedObjects)
if (clonedObjects.hasOwnProperty(x))
if (clonedObjects[x].id == key)
delete clonedObjects[x];
$scope.yourModel = clonedObjects;
}
The $scope.yourModel will be updated with the clonedObjects.
Hope that helps.
You need other headers, not only access-control-allow-origin. If your request have the "Access-Control-Allow-Origin" header, you must copy it into the response headers, If doesn't, you must check the "Origin" header and copy it into the response. If your request doesn't have Access-Control-Allow-Origin not Origin headers, you must return "*".
You can read the complete explanation here: http://www.html5rocks.com/en/tutorials/cors/#toc-adding-cors-support-to-the-server
and this is the function I'm using to write cross domain headers:
func writeCrossDomainHeaders(w http.ResponseWriter, req *http.Request) {
// Cross domain headers
if acrh, ok := req.Header["Access-Control-Request-Headers"]; ok {
w.Header().Set("Access-Control-Allow-Headers", acrh[0])
}
w.Header().Set("Access-Control-Allow-Credentials", "True")
if acao, ok := req.Header["Access-Control-Allow-Origin"]; ok {
w.Header().Set("Access-Control-Allow-Origin", acao[0])
} else {
if _, oko := req.Header["Origin"]; oko {
w.Header().Set("Access-Control-Allow-Origin", req.Header["Origin"][0])
} else {
w.Header().Set("Access-Control-Allow-Origin", "*")
}
}
w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE")
w.Header().Set("Connection", "Close")
}

If you have several dialogs that could be opened on a page, this will allow any of them to be closed by clicking on the background:
$('body').on('click','.ui-widget-overlay', function() {
$('.ui-dialog').filter(function () {
return $(this).css("display") === "block";
}).find('.ui-dialog-content').dialog('close');
});
(Only works for modal dialogs, as it relies on '.ui-widget-overlay'. And it does close all open dialogs any time the background of one of them is clicked.)
I had the same issue. This is my solution using angular documentation and firebase Token:
getService() {
const accessToken=this.afAuth.auth.currentUser.getToken().then(res=>{
const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
'Authorization': res
})
};
return this.http.get('Url',httpOptions)
.subscribe(res => console.log(res));
}); }}
You could catch the NullPointerException
explicitly and ignore it - though its generally not recommended. You should not, however, ignore all exceptions as you're currently doing.
UserInfo ui = new UserInfo();
try {
DirectoryUser du = LDAPService.findUser(username);
if (du!=null) {
ui.setUserInfo(du.getUserInfo());
}
} catch (NullPointerException npe) {
// Lulz @ your NPE
Logger.log("No user info for " +username+ ", will find some way to cope");
}
As in interface,we are just declaring methods,concrete class which implements these both interfaces understands is that there is only one method(as you described both have same name in return type). so there should not be an issue with it.You will be able to define that method in concrete class.
But when two interface have a method with the same name but different return type and you implement two methods in concrete class:
Please look at below code:
public interface InterfaceA {
public void print();
}
public interface InterfaceB {
public int print();
}
public class ClassAB implements InterfaceA, InterfaceB {
public void print()
{
System.out.println("Inside InterfaceA");
}
public int print()
{
System.out.println("Inside InterfaceB");
return 5;
}
}
when compiler gets method "public void print()" it first looks in InterfaceA and it gets it.But still it gives compile time error that return type is not compatible with method of InterfaceB.
So it goes haywire for compiler.
In this way, you will not be able to implement two interface having a method of same name but different return type.
Your trying to load the lazy loaded collection, but the hibernate session is closed or unavailable. the best solution for this problem, change the lazy loaded object to eager fetch = FetchType.EAGER loading. this problem will solve.
The accepted answer works for columns that are of datatype string
. For completeness: I come across this question when searching how to do this when the columns are of datatypes: date and time.
df.apply(lambda r : pd.datetime.combine(r['date_column_name'],r['time_column_name']),1)
Try the following
static Dictionary<TKey, TValue>
Merge<TKey, TValue>(this IEnumerable<Dictionary<TKey, TValue>> enumerable)
{
return enumerable.SelectMany(x => x).ToDictionary(x => x.Key, y => y.Value);
}
Just use:
pwd | xargs basename
or
basename "`pwd`"

There are a few ways to run a batch file on start up. The one I usually use is through task scheduler. If you press the windows key then type task scheduler it will come up as an option (or find through administerative tools).
When you create a new task you can chose from trigger options such as 'At log on' for a specific user, on workstation unlock etc. Then in actions you select start a program and put the full path to your batch script (there is also an option to put any command line args required).

Those are "non-client" areas and are controlled by Windows. Here is the MSDN docs on the subject (the pertinent info is at the top).
Basically, you set your Window's WindowStyle="None", then build your own window interface. (similar question on SO)
Finally resolved my java install issue on Win 7 64-bit running IE11.
Even though I installed the latest Java (65) via a java auto-update prompt, tried a verify java version and java failed to run, shut down all IE instances, failed to run verify again, shut down all running programs, failed to run verify again, rebooted, failed to run verify again, re-installed 65 again (shutting down the browser manually as it downloaded), and finally verify ran. What a pain.
The message I kept receiving was "The page you are viewing uses Java ..."; e.g. https://www.java.com/en/download/help/ie_tips.xml. I do use sleep mode on my desktop and I believe that this is probably the major issue with install and IE with its "clever" integration into the OS and explorer/desktop. I thought the government told them to not do that. I've had issues with CD-ROM drive disappearing and other unexplained periodic issues; all cured after a full reboot. They are infrequent, so I live with them for the convenience of faster startup times.
Hope this helps someone!
I have finally got this working. It expands on the solution from A. Garcia, however, since the problem lies in the hibernate type MaterializedBlob type just mapping Blob > bytea is not sufficient, we need a replacement for MaterializedBlobType which works with hibernates broken blob support. This implementation only works with bytea, but maybe the guy from the JIRA issue who wanted OID could contribute an OID implementation.
Sadly replacing these types at runtime is a pain, since they should be part of the Dialect. If only this JIRA enhanement gets into 3.6 it would be possible.
public class PostgresqlMateralizedBlobType extends AbstractSingleColumnStandardBasicType<byte[]> {
public static final PostgresqlMateralizedBlobType INSTANCE = new PostgresqlMateralizedBlobType();
public PostgresqlMateralizedBlobType() {
super( PostgresqlBlobTypeDescriptor.INSTANCE, PrimitiveByteArrayTypeDescriptor.INSTANCE );
}
public String getName() {
return "materialized_blob";
}
}
Much of this could probably be static (does getBinder() really need a new instance?), but I don't really understand the hibernate internal so this is mostly copy + paste + modify.
public class PostgresqlBlobTypeDescriptor extends BlobTypeDescriptor implements SqlTypeDescriptor {
public static final BlobTypeDescriptor INSTANCE = new PostgresqlBlobTypeDescriptor();
public <X> ValueBinder<X> getBinder(final JavaTypeDescriptor<X> javaTypeDescriptor) {
return new PostgresqlBlobBinder<X>(javaTypeDescriptor, this);
}
public <X> ValueExtractor<X> getExtractor(final JavaTypeDescriptor<X> javaTypeDescriptor) {
return new BasicExtractor<X>( javaTypeDescriptor, this ) {
protected X doExtract(ResultSet rs, String name, WrapperOptions options) throws SQLException {
return (X)rs.getBytes(name);
}
};
}
}
public class PostgresqlBlobBinder<J> implements ValueBinder<J> {
private final JavaTypeDescriptor<J> javaDescriptor;
private final SqlTypeDescriptor sqlDescriptor;
public PostgresqlBlobBinder(JavaTypeDescriptor<J> javaDescriptor, SqlTypeDescriptor sqlDescriptor) {
this.javaDescriptor = javaDescriptor; this.sqlDescriptor = sqlDescriptor;
}
...
public final void bind(PreparedStatement st, J value, int index, WrapperOptions options)
throws SQLException {
st.setBytes(index, (byte[])value);
}

The bottom of the javadoc for the java.util package contains some good links:
You can set custom font in two ways : design time
and run-time
.
First you need to download required font
(.ttf file format). Then, double click on the file to install it.
This will show a pop-up. Click on 'install font
' button.
'Fonts'
window.Add to targets
' is checked.Copy Bundle Resources'
present in Build Phases
of Targets
of your project.Info.plist
of your project.
Create a new key with 'Font Provided by application
' with type as Array.
Add a the font as an element with type String in Array.A. Design mode :
Font
attribute present in Attribute inspector
of Utilities
.B. Run-time mode :
self.lblWelcome.font = UIFont(name: "BananaYeti-Extrabold Trial", size: 16)
It seems that run-time mode doesn't work for dynamically formed string like
self.lblWelcome.text = "Welcome, " + fullname + "!"
Note that in above case only design-time approach worked correctly for me.
For a solution that worked well with third party controls like Telerik (ex.: RadComboBox) and DevExpress that use the Anchor tags for various reasons, consider using the following code, which is a slightly tweaked version of desm's code with a better selector for self targeting anchor tags:
var inFormOrLink;
$('a[href]:not([target]), a[href][target=_self]').live('click', function() { inFormOrLink = true; });
$('form').bind('submit', function() { inFormOrLink = true; });
$(window).bind('beforeunload', function(eventObject) {
var returnValue = undefined;
if (! inFormOrLink) {
returnValue = "Do you really want to close?";
}
eventObject.returnValue = returnValue;
return returnValue;
});
Get the real path to your script
if [ -L $0 ] ; then
ME=$(readlink $0)
else
ME=$0
fi
DIR=$(dirname $ME)

Try this
@RequestMapping(value = "proffessional", method = RequestMethod.POST)
public @ResponseBody
String forgotPassword(@ModelAttribute("PROFESSIONAL") UserProfessionalForm professionalForm,
BindingResult result, Model model) {
UserProfileVO userProfileVO = new UserProfileVO();
userProfileVO.setUser(sessionData.getUser());
userService.saveUserProfile(userProfileVO);
model.addAttribute("professional", professionalForm);
return "Your Professional Details Updated";
}
You can also use a third party library that makes life easy, like Just

It sounds like you want to use a transparent background, in which case you could try using the rgba()
function:
rgba(R, G, B, A)
R (red), G (green), and B (blue) can be either
<integer>
s or<percentage>
s, where the number 255 corresponds to 100%. A (alpha) can be a<number>
between 0 and 1, or a<percentage>
, where the number 1 corresponds to 100% (full opacity).RGBa example
rgba(51, 170, 51, .1) /* 10% opaque green */ rgba(51, 170, 51, .4) /* 40% opaque green */ rgba(51, 170, 51, .7) /* 70% opaque green */ rgba(51, 170, 51, 1) /* full opaque green */
A small example showing how rgba
can be used.
As of 2018, practically every browser supports the rgba
syntax.
As explained in the accepted answer, https://stackoverflow.com/a/18665488/4038790, you need to check via a server.
Because there's no reliable way to check this in the browser, I suggest you build yourself a quick server endpoint that you can use to check if any url is loadable via iframe. Once your server is up and running, just send a AJAX request to it to check any url by providing the url in the query string as url
(or whatever your server desires). Here's the server code in NodeJs:
const express = require('express')_x000D_
const app = express()_x000D_
_x000D_
app.get('/checkCanLoadIframeUrl', (req, res) => {_x000D_
const request = require('request')_x000D_
const Q = require('q')_x000D_
_x000D_
return Q.Promise((resolve) => {_x000D_
const url = decodeURIComponent(req.query.url)_x000D_
_x000D_
const deafultTimeout = setTimeout(() => {_x000D_
// Default to false if no response after 10 seconds_x000D_
resolve(false)_x000D_
}, 10000)_x000D_
_x000D_
request({_x000D_
url,_x000D_
jar: true /** Maintain cookies through redirects */_x000D_
})_x000D_
.on('response', (remoteRes) => {_x000D_
const opts = (remoteRes.headers['x-frame-options'] || '').toLowerCase()_x000D_
resolve(!opts || (opts !== 'deny' && opts !== 'sameorigin'))_x000D_
clearTimeout(deafultTimeout)_x000D_
})_x000D_
.on('error', function() {_x000D_
resolve(false)_x000D_
clearTimeout(deafultTimeout)_x000D_

None of the answers address the point of this design choice. I think docker works this way to prevent these 2 errors:
If your OS uses the Linux kernel, there is a simple way to get all the words from the English/American dictionary. In the directory /usr/share/dict
you have a words
file. There is also a more specific american-english
and british-english
files. These contain all of the words in that specific language. You can access this throughout every programming language which is why I thought you might want to know about this.
Now, for python specific users, the python code below should assign the list words to have the value of every single word:
import re
file = open("/usr/share/dict/words", "r")
words = re.sub("[^\w]", " ", file.read()).split()
def is_word(word):
return word.lower() in words
is_word("tarts") ## Returns true
is_word("jwiefjiojrfiorj") ## Returns False
Hope this helps!!!
Websites are primarily informational. In this sense, http://cnn.com and http://php.net are websites, not web applications.
Web applications primarily allow the user to perform actions. Google Analytics, gmail, and jslint are web applications.
They are not entirely exclusive. A university website likely gives information such as location, tuition rates, programs available, etc; it will likely have web applications that allow teachers to manage grades and course materials, applications for students to register for and withdraw from courses, etc.
The date function would be defined something like this:
function date($format, $timestamp = null)
{
if ($timestamp === null) {
$timestamp = time();
}
// Format the timestamp according to $format
}
Usually, you would put the default value like this:
function foo($required, $optional = 42)
{
// This function can be passed one or more arguments
}
However, only literals are valid default arguments, which is why I used null
as default argument in the first example, not $timestamp = time()
, and combined it with a null check. Literals include arrays (array()
or []
), booleans, numbers, strings, and null
.
If someone else needs a generic utility type to do this, I came up with the following solution:
/**
* Returns object T, but with T[K] overridden to type U.
* @example
* type MyObject = { a: number, b: string }
* OverrideProperty<MyObject, "a", string> // returns { a: string, b: string }
*/
export type OverrideProperty<T, K extends keyof T, U> = Omit<T, K> & { [P in keyof Pick<T, K>]: U };
I needed this because in my case, the key to override was a generic itself.
If you don't have Omit
ready, see Exclude property from type.

If browser supports iframe, then DOM inside iframe come from src attribute of respective tag. Contents that are inside iframe tag are used as a fall back mechanism where browser does not supports iframe tag.
I realize this is pretty late, but I had a similar problem and I figured I'd post what worked for me. I used the iconv utility (e.g., "iconv file.pcl -f UTF-8 -t ISO-8859-1 -c"
). The "-c" option skips characters that can't be translated.
& is a keyword for the next parameter like this ur?param1=1¶m2=2
so effectively you send a second param named R". You should urlencode
your string. Isn't POST an option?
Other answers posted here for this question did not work for me using the latest Visual Studio 2017 Enterprise edition (as of 2018-09-18).
Instead, I used this method:
Once installed, close and restart Visual Studio. Go to File->New Project and search for the word Installer. You'll know you have the correct templates installed if you see a list that looks something like this:
Block
Takes up the full width available, with a new line before and after (display:block;)
Inline
Takes up only as much width as it needs, and does not force new lines (display:inline;)
It is a unary operator (taking a single argument) that is borrowed from C, where all data types are just different ways of interpreting bytes. It is the "invert" or "complement" operation, in which all the bits of the input data are reversed.
In Python, for integers, the bits of the twos-complement representation of the integer are reversed (as in b <- b XOR 1
for each individual bit), and the result interpreted again as a twos-complement integer. So for integers, ~x
is equivalent to (-x) - 1
.
The reified form of the ~
operator is provided as operator.invert
. To support this operator in your own class, give it an __invert__(self)
method.
>>> import operator
>>> class Foo:
... def __invert__(self):
... print 'invert'
...
>>> x = Foo()
>>> operator.invert(x)
invert
>>> ~x
invert
Any class in which it is meaningful to have a "complement" or "inverse" of an instance that is also an instance of the same class is a possible candidate for the invert operator. However, operator overloading can lead to confusion if misused, so be sure that it really makes sense to do so before supplying an __invert__
method to your class. (Note that byte-strings [ex: '\xff'
] do not support this operator, even though it is meaningful to invert all the bits of a byte-string.)
If that really is all that's in your CSS file, then yes, nothing will happen. You need a selector, even if it's as simple as body
:
body {
background-image: url(...);
}
Once you got the ZIP from the download, extract it locally, and with your finder, go in bin

The original code is mostly there, but you need btn-group
s around each button. In Bootstrap 3 you can use a btn-toolbar and a btn-group to get the job done; I haven't done BS4 but it has similar constructs.
<div class="btn-toolbar" role="toolbar">
<div class="btn-group" role="group">
<button class="btn btn-default">Button 1</button>
</div>
<div class="btn-group" role="group">
<button class="btn btn-default">Button 2</button>
</div>
</div>
You can also disable browser caching with meta HTML tags just put html tags in the head section to avoid the web page to be cached while you are coding/testing and when you are done you can remove the meta tags.
(in the head section)
<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0"/>
Refresh your page after pasting this in the head and should refresh the new javascript code too.
This link will give you other options if you need them http://cristian.sulea.net/blog/disable-browser-caching-with-meta-html-tags/
or you can just create a button like so
<button type="button" onclick="location.reload(true)">Refresh</button>
it refreshes and avoid caching but it will be there on your page till you finish testing, then you can take it off. Fist option is best I thing.
You can always use the 'pre' tag inside the label, and just enter the blank spaces in it, So you can always add the same or different number of spaces you require
<form>
<label>First Name :<pre>Here just enter number of spaces you want to use(I mean using spacebar to enter blank spaces)</pre>
<input type="text"></label>
<label>Last Name :<pre>Now Enter enter number of spaces to match above number of
spaces</pre>
<input type="text"></label>
</form>
Hope you like my answer, It's a simple and efficient hack
\i /path/to/yourfile.sql
another a bit more functional way to check list equality for list 1 (lst1) and list 2 (lst2) where objects have depth one and which keeps the order is:
all(i == j for i, j in zip(lst1, lst2))
@Rene Juuse - above in comments... Thanks for this link !
. the code to get the real path is a bit different from one SDK to another so below we have three methods that deals with different SDKs.

UPDATE 2016 March
To fix all problems with path of images i try create a custom gallery as facebook and other apps. This is because you can use just local files ( real files, not virtual or temporary) , i solve all problems with this library.
https://github.com/nohana/Laevatein (this library is to take photo from camera or choose from galery , if you choose from gallery he have a drawer with albums and just show local files)
$('input, select').attr('disabled', 'disabled');

I suggest using jQuery. What you are doing right now is easy to achieve without jQuery, but as you will want new features and more functionality, jQuery will save you a lot of time. I would also like to mention that you shouldn't have multiple DOM elements with the same ID in one document. In such case use class attribute.
html:
<table id="dsTable">
<tr>
<td> Relationship Type </td>
<td> Date of Birth </td>
<td> Gender </td>
</tr>
<tr>
<td> Spouse </td>
<td> 1980-22-03 </td>
<td> female </td>
<td> <input type="button" class="addDep" value="Add"/></td>
<td> <input type="button" class="deleteDep" value="Delete"/></td>
</tr>
<tr>
<td> Child </td>
<td> 2008-23-06 </td>
<td> female </td>
<td> <input type="button" class="addDep" value="Add"/></td>
<td> <input type="button" class="deleteDep" value="Delete"/></td>
</tr>
</table>
javascript:
$('body').on('click', 'input.deleteDep', function() {
$(this).parents('tr').remove();
});
Remember that you need to reference jQuery:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
Here a working jsfiddle example: http://jsfiddle.net/p9dey/1/
The usual way would be:
if (a instanceof A)
However, there are cases when you can't do this, such as when A
in a generic argument.
Due to Java's type erasure, the following won't compile:
<A> boolean someMethod(Object a) {
if (a instanceof A)
...
}
and the following won't work (and will produce an unchecked cast
warning):
<A> void someMethod(Object a) {
try {
A casted = (A)a;
} catch (ClassCastException e) {
...
}
}
You can't cast to A
at runtime, because at runtime, A
is essentially Object
.
The solutions to such cases is to use a Class
instead of the generic argument:
void someMethod(Object a, Class<A> aClass) {
if (aClass.isInstance(a)) {
A casted = aClass.cast(a);
...
}
}
You can then call the method as:
someMethod(myInstance, MyClass.class);
someMethod(myInstance, OtherClass.class);
You're looking for the toggle_comment
command. (Edit > Comment > Toggle Comment)
By default, this command is mapped to:
This command also takes a block
argument, which allows you to use block comments instead of single lines (e.g. /* ... */
as opposed to // ...
in JavaScript). By default, the following key combinations are mapped to toggle block comments:

Getting rows from DB:
public static DataRowCollection getAllUsers(string tableName)
{
DataSet set = new DataSet();
SqlCommand comm = new SqlCommand();
comm.Connection = DAL.DAL.conn;
comm.CommandType = CommandType.StoredProcedure;
comm.CommandText = "getAllUsers";
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = comm;
da.Fill(set,tableName);
DataRowCollection usersCollection = set.Tables[tableName].Rows;
return usersCollection;

Populating DataGridView from DataRowCollection :
public static void ShowAllUsers(DataGridView grdView,string table, params string[] fields)
{
DataRowCollection userSet = getAllUsers(table);
foreach (DataRow user in userSet)
{
grdView.Rows.Add(user[fields[0]],
user[fields[1]],
user[fields[2]],
user[fields[3]]);
}
}
Implementation :
BLL.BLL.ShowAllUsers(grdUsers,"eusers","eid","euname","eupassword","eposition");
I had the same problem. Solution: I edit the file with pspad editor, and give it a unix format (Menu - Format -> UNIX)
I believe you can set this format to your file with many other editors
I was using Eclipse as IDE and I was getting very same error. I had to do Project->Maven->Update Project. Select all the checkboxes below except "offline" esp. the one "Force update of snapshots/releases" and click OK. Did the Clean Build for the Project again.
use the %f
modifier:
sprintf (str, "adc_read = %f\n", adc_read);
For instance:
#include <stdio.h>
int main (void)
{
float x = 2.5;
char y[200];
sprintf(y, "x = %f\n", x);
printf(y);
return 0;
}
Yields this:
x = 2.500000

You can not color plain text in a GitHub README.md file. You can however add color to code samples in your GitHub README.md file with the tags below.
To do this, just add tags, such as these samples, to your README.md file:
```json // Code for coloring ``` ```html // Code for coloring ``` ```js // Code for coloring ``` ```css // Code for coloring ``` // etc.
import { Component } from '@angular/core'; import { MovieService } from './services/movie.service'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'], providers: [ MovieService ] }) export class AppComponent { title = 'app works!'; }
No "pre" or "code" tags are needed.
This is now covered in the GitHub Markdown documentation (about half way down the page, there's an example using Ruby). GitHub uses Linguist to identify and highlight syntax - you can find a full list of supported languages (as well as their markdown keywords) over in the Linguist's YAML file.
if(list.ElementAtOrDefault(2) != null)
{
// logic
}
ElementAtOrDefault() is part of the System.Linq
namespace.
Although you have a List, so you can use list.Count > 2
.
There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.
Similarity::Similarity()
or Similarity::~Similarity()
are just missing and you have defined the others incorrectly,
void Similarity::readData(Scanner& inStream){
}
not
void readData(Scanner& inStream){
}
etc. etc.
The second one is a function called readData, only the first is the readData method of the Similarity class.
To be clear about this, in Similarity.h
void readData(Scanner& inStream);
but in Similarity.cpp
void Similarity::readData(Scanner& inStream){
}
Use newid()
select newid()
or possibly this
select binary_checksum(newid())
The size_t
type is defined as the unsigned integral type of the sizeof
operator. In the real world, you will often see int
defined as 32 bits (for backward compatibility) but size_t
defined as 64 bits (so you can declare arrays and structures more than 4 GiB in size) on 64-bit platforms. If a long int
is also 64-bits, this is called the LP64 convention; if long int
is 32 bits but long long int
and pointers are 64 bits, that’s LLP64. You also might get the reverse, a program that uses 64-bit instructions for speed, but 32-bit pointers to save memory. Also, int
is signed and size_t
is unsigned.
There were historically a number of other platforms where addresses were wider or shorter than the native size of int
. In fact, in the ’70s and early ’80s, this was more common than not: all the popular 8-bit microcomputers had 8-bit registers and 16-bit addresses, and the transition between 16 and 32 bits also produced many machines that had addresses wider than their registers. I occasionally still see questions here about Borland Turbo C for MS-DOS, whose Huge memory mode had 20-bit addresses stored in 32 bits on a 16-bit CPU (but which could support the 32-bit instruction set of the 80386); the Motorola 68000 had a 16-bit ALU with 32-bit registers and addresses; there were IBM mainframes with 15-bit, 24-bit or 31-bit addresses. You also still see different ALU and address-bus sizes in embedded systems.
Any time int
is smaller than size_t
, and you try to store the size or offset of a very large file or object in an unsigned int
, there is the possibility that it could overflow and cause a bug. With an int
, there is also the possibility of getting a negative number. If an int
or unsigned int
is wider, the program will run correctly but waste memory.
You should generally use the correct type for the purpose if you want portability. A lot of people will recommend that you use signed math instead of unsigned (to avoid nasty, subtle bugs like 1U < -3
). For that purpose, the standard library defines ptrdiff_t
in <stddef.h>
as the signed type of the result of subtracting a pointer from another.
That said, a workaround might be to bounds-check all addresses and offsets against INT_MAX
and either 0
or INT_MIN
as appropriate, and turn on the compiler warnings about comparing signed and unsigned quantities in case you miss any. You should always, always, always be checking your array accesses for overflow in C anyway.
For the first rule,
Click "greater than", then in the value option box, click on the cell criteria you want it to be less than, than use the format drop-down to select your color.
For the second,
Click "less than", then in the value option box, type "=.9*" and then click the cell criteria, then use the formatting just like step 1.
For the third,
Same as the second, except your formula is =".8*" rather than .9.
I would try to using pointers to solve this problem:
#include <iostream>
void displayArray(int table[], int size);
void rev(int table[], int size);
int main(int argc, char** argv) {
int a[10] = { 1,2,3,4,5,6,7,8,9,10 };
rev(a, 10);
displayArray(a, 10);
return 0;
}
void displayArray(int table[], int size) {
for (int i = 0; i < size; i++) {
std::cout << table[i] << " ";
}
std::cout << std::endl;
}
void rev(int table[], int size) {
int *start = table;
int *end = table + (size - 1);
for (int i = 0; i < size; i++) {
if (start < end) {
int temp = *end;
*end = *start;
*start = temp;
}
start++;
end--;
}
}
You can combine both in the same date function call
date("d-m-Y H:i:s");
For substracting in moment.js:
moment().subtract(1, 'months').format('MMM YYYY');
Documentation:
http://momentjs.com/docs/#/manipulating/subtract/
Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).
moment().subtract('seconds', 1); // Deprecated in 2.8.0
moment().subtract(1, 'seconds');
As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.
moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8
Let's dissect it. There are three parts:
cd
-- This is change directory command./d
-- This switch makes cd
change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0
. (%~d0
Changs active drive, cd %~p0
change the directory).%~dp0
-- This can be dissected further into three parts:
%0
-- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.%~0
-- The ~
there strips double quotes ("
) around the expanded argument.%dp0
-- The d
and p
there are modifiers of the expansion. The d
forces addition of a drive letter and the p
adds full path.This is 2 years old, but none of them helped me.
I uninstalled my NodeJS v12.8.1 (Current) and installed a brand new v10.16.3 (LTS) and my ng build --prod
worked.
Yes - just explicitly provide the path to java.exe. For instance:
c:\Users\Jon\Test>"c:\Program Files\java\jdk1.6.0_03\bin\java.exe" -version
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)
c:\Users\Jon\Test>"c:\Program Files\java\jdk1.6.0_12\bin\java.exe" -version
java version "1.6.0_12"
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) Client VM (build 11.2-b01, mixed mode, sharing)
The easiest way to do this for a running command shell is something like:
set PATH=c:\Program Files\Java\jdk1.6.0_03\bin;%PATH%
For example, here's a complete session showing my default JVM, then the change to the path, then the new one:
c:\Users\Jon\Test>java -version
java version "1.6.0_12"
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) Client VM (build 11.2-b01, mixed mode, sharing)
c:\Users\Jon\Test>set PATH=c:\Program Files\Java\jdk1.6.0_03\bin;%PATH%
c:\Users\Jon\Test>java -version
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)
This won't change programs which explicitly use JAVA_HOME though.
Note that if you get the wrong directory in the path - including one that doesn't exist - you won't get any errors, it will effectively just be ignored.
I was getting similar errors and eventually found just that cleaning the build folder resolved my issue.

Consider process like a unit of ownership or what resources are needed by a task. A Process can have resources like memory space, specific input/output, specific files, and priority etc.
A thread is a dispatchable unit of execution or in simple words the progress through a sequence of instructions
This is a highly inefficient way of doing it. You can use the merge
statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.
MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
UPDATE SET l.studName = s.studName
WHERE l.studName != s.studName
WHEN NOT MATCHED THEN
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)
Make sure you commit
, once completed, in order to be able to see this in the database.
To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.
It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.
However, as I say this will not be as efficient as merge
.
declare
cursor c_data is
select b.rowid as rid, a.studId, a.studName
from student a
left outer join studLoad b
on a.studId = b.studId
and a.studName <> b.studName
;
type t__data is table of c_data%rowtype index by binary_integer;
t_data t__data;
begin
open c_data;
loop
fetch c_data bulk collect into t_data limit 10000;
exit when t_data.count = 0;
for idx in t_data.first .. t_data.last loop
if t_data(idx).rid is null then
insert into studLoad (studId, studName)
values (t_data(idx).studId, t_data(idx).studName);
else
update studLoad
set studName = t_data(idx).studName
where rowid = t_data(idx).rid
;
end if;
end loop;
end loop;
close c_data;
end;

Clone the repository as normal:
git clone git://github.com/rspec/rspec-tmbundle.git RSpec.tmbundle
Then checkout the tag you want like so:
git checkout tags/1.1.4
This will checkout out the tag in a 'detached HEAD' state. In this state, "you can look around, make experimental changes and commit them, and [discard those commits] without impacting any branches by performing another checkout".
To retain any changes made, move them to a new branch:
git checkout -b 1.1.4-jspooner
You can get back to the master branch by using:
git checkout master
Note, as was mentioned in the first revision of this answer, there is another way to checkout a tag:
git checkout 1.1.4
But as was mentioned in a comment, if you have a branch by that same name, this will result in git warning you that the refname is ambiguous and checking out the branch by default:
warning: refname 'test' is ambiguous.
Switched to branch '1.1.4'
The shorthand can be safely used if the repository does not share names between branches and tags.
If the data is not null-terminated, you should use -initWithData:encoding:
NSString* newStr = [[NSString alloc] initWithData:theData encoding:NSUTF8StringEncoding];
If the data is null-terminated, you should instead use -stringWithUTF8String:
to avoid the extra \0
at the end.
NSString* newStr = [NSString stringWithUTF8String:[theData bytes]];
(Note that if the input is not properly UTF-8-encoded, you will get nil
.)
let newStr = String(data: data, encoding: .utf8)
// note that `newStr` is a `String?`, not a `String`.
If the data is null-terminated, you could go though the safe way which is remove the that null character, or the unsafe way similar to the Objective-C version above.
// safe way, provided data is \0-terminated
let newStr1 = String(data: data.subdata(in: 0 ..< data.count - 1), encoding: .utf8)
// unsafe way, provided data is \0-terminated
let newStr2 = data.withUnsafeBytes(String.init(utf8String:))
If you're using the TortoiseSVN client, it's easily done via the Show Log dialog.
After spending about two hours trying to come up with a solution I realized that I had adblockers blocking the call to GA. Once I turned them off I was good to go.
Just a quick update on what has worked for me (two years later). Davis King has provided two ways to add the latest python dlib (19.17.0) to any python environment in Windows 10 for me. Note, I run several Linux configs in Oracle VirtualBox but Windows 10 is my native OS which has access to the Nvidia GPU so i need an install on Windows 10. (Cannot access the GPU - easily - through VirtualBox).
First - the easiest:
pip install dlib
and the website link: https://pypi.org/project/dlib/
And then it can be easily be build from sources. Download from https://pypi.org/simple/dlib/ and follow instructions on http://dlib.net/compile.html.
Also, just found another way to access with Visual Studio 2019 (or 2017). Use vcpkg - see link https://vcpkg.readthedocs.io/en/latest/
I built dlib 19.17 on Windows 10 with CMake and it worked fine but then I found vcpkg and now the dlib libraries are integral to the Visual Studio. I no longer need to add all the external links to C++ and the linker.The version in vcpkg is currently 19.16-1 and it is built with full CUDA support.
Hope this helps others..
Instead of naming my invoking class, I started using the following:

In this way, I can use the same line of code in every class that uses log4net without having to remember to change code when I copy and paste. Alternatively, i could create a logging class, and have every other class inherit from my logging class.
This isn't very well documented, but we can trigger any kinds of events very simply.
This example will trigger 50 double click on the button:
let theclick = new Event("dblclick")
for (let i = 0;i < 50;i++){
action.dispatchEvent(theclick)
}
_x000D_
<button id="action" ondblclick="out.innerHTML+='Wtf '">TEST</button>
<div id="out"></div>
_x000D_
The Event interface represents an event which takes place in the DOM.
An event can be triggered by the user action e.g. clicking the mouse button or tapping keyboard, or generated by APIs to represent the progress of an asynchronous task. It can also be triggered programmatically, such as by calling the HTMLElement.click() method of an element, or by defining the event, then sending it to a specified target using EventTarget.dispatchEvent().

yeah you're not going to have much luck i think. Typically across the 3 drawing methods the major browsers use (Canvas, SVG, VML), text support is poor, I believe. If you want to rotate an image, then it's all good, but if you've got mixed content with formatting and styles, probably not.
Check out RaphaelJS for a cross-browser drawing API.
Override all methods
@Override
public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {
}
@Override
public void onStartTrackingTouch(SeekBar arg0) {
}
@Override
public void onStopTrackingTouch(SeekBar arg0) {
}
TO ADD: @Christopher's answer does not work on API 7/8 (as per @Jonny's correct comment) IF you are using colours, instead of drawables. (In my testing, using drawables as per Christopher works fine)
Here is the FIX for 2.3 and below when using colours:
As per @Charles Harley, there is a bug in 2.3 and below where filling the list item with a colour causes the colour to flow out over the whole list. His fix is to define a shape
drawable containing the colour you want, and to use that instead of the colour.
I suggest looking at this link if you want to just use a colour as selector, and are targeting Android 2 (or at least allow for Android 2).
if you want to disable the values of the dropdown
$('select option:not(selected)').prop('disabled', true);
$('select').prop('disabled', true);
foreach (var data in dynObj.quizlist)
{
foreach (var data1 in data.QUIZ.QPROP)
{
Response.Write("Name" + ":" + data1.name + "<br>");
Response.Write("Intro" + ":" + data1.intro + "<br>");
Response.Write("Timeopen" + ":" + data1.timeopen + "<br>");
Response.Write("Timeclose" + ":" + data1.timeclose + "<br>");
Response.Write("Timelimit" + ":" + data1.timelimit + "<br>");
Response.Write("Noofques" + ":" + data1.noofques + "<br>");
foreach (var queprop in data1.QUESTION.QUEPROP)
{
Response.Write("Questiontext" + ":" + queprop.questiontext + "<br>");
Response.Write("Mark" + ":" + queprop.mark + "<br>");
}
}
}
I used the second solution of user147767
However, there is a typo here. It should be
curCssName.toUpperCase().indexOf(cssName.toUpperCase() + ':') < 0
not <= 0
I also changed this condition for:
!curCssName.match(new RegExp(cssName + "(-.+)?:"), "mi")
as sometimes we add a css property over jQuery, and it's added in a different way for different browsers (i.e. the border property will be added as "border" for Firefox, and "border-top", "border-bottom" etc for IE).
C# equivalent of your code is
class Imagedata : PDFStreamEngine
{
// C# uses "base" keyword whenever Java uses "super"
// so instead of super(...) in Java we should call its C# equivalent (base):
public Imagedata()
: base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true))
{ }
// Java methods are virtual by default, when C# methods aren't.
// So we should be sure that processOperator method in base class
// (that is PDFStreamEngine)
// declared as "virtual"
protected override void processOperator(PDFOperator operations, List arguments)
{
base.processOperator(operations, arguments);
}
}
According to the documentation:
The WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD instructions that follow it in the Dockerfile. If the WORKDIR doesn’t exist, it will be created even if it’s not used in any subsequent Dockerfile instruction.
Also, in the Docker best practices it recommends you to use it:
... you should use WORKDIR instead of proliferating instructions like RUN cd … && do-something, which are hard to read, troubleshoot, and maintain.
I would suggest to keep it.
I think you can refactor your Dockerfile to something like:
FROM node:latest
WORKDIR /usr/src/app
COPY package.json .
RUN npm install
COPY . ./
EXPOSE 3000
CMD [ “npm”, “start” ]
Recently Raymond Chen also ran an interesting series of articles on the yield keyword.
While it's nominally used for easily implementing an iterator pattern, but can be generalized into a state machine. No point in quoting Raymond, the last part also links to other uses (but the example in Entin's blog is esp good, showing how to write async safe code).
Interesting question.
If you can't find a better method, you can always replace.
In case you're opting for it, you could use this C# Escape Sequence List:
This list can be found in the C# Frequently Asked Questions What character escape sequences are available?
For RPM-based distributions(like Fedora 19), after running the sudo pip install virtualenvwrapper
command, you may find the file at:
/usr/bin/virtualenvwrapper.sh
sql = "insert into Main (Firt Name, Last Name) values(textbox2.Text,textbox3.Text)";
(Firt Name) is not a valid field. It should be FirstName or First_Name. It may be your problem.
Bdizzle,
I would recommend that you read this link
You will see that Newsletters can have different widths, There seems to be no major standard, What is recommended is that the width will be about 95% of the page width, as different browsers use the extra margins differently. You will also find that email readers have problems when reading css so applying the guide lines in this tutorial might help you save some time and trouble-shooting down the road.
Be happy, Julian
Or just :
var a:Int = 3
var b:Int = 3
println(pow(Double(a),Double(b)))
You can do it by using name attibute, class, id or just universal checkbox; If you want to count only checked number of checkbox.
By the class name :
var countChk = $('checkbox.myclassboxName:checked').length;
By name attribute :
var countByName= $('checkbox[name=myAllcheckBoxName]:checked').length;
$('checkbox.className').blur(function() {
//count only checked checkbox
$('checkbox[name=myAllcheckBoxName]:checked').length;
});
It is not possible to resize an array. However, it is possible change the size of an array through copying the original array to the newly sized one and keep the current elements. The array can also be reduced in size by removing an element and resizing.
import java.util.Arrays
public class ResizingArray {
public static void main(String[] args) {
String[] stringArray = new String[2] //A string array with 2 strings
stringArray[0] = "string1";
stringArray[1] = "string2";
// increase size and add string to array by copying to a temporary array
String[] tempStringArray = Arrays.copyOf(stringArray, stringArray.length + 1);
// Add in the new string
tempStringArray[2] = "string3";
// Copy temp array to original array
stringArray = tempStringArray;
// decrease size by removing certain string from array (string1 for example)
for(int i = 0; i < stringArray.length; i++) {
if(stringArray[i] == string1) {
stringArray[i] = stringArray[stringArray.length - 1];
// This replaces the string to be removed with the last string in the array
// When the array is resized by -1, The last string is removed
// Which is why we copied the last string to the position of the string we wanted to remove
String[] tempStringArray2 = Arrays.copyOf(arrayString, arrayString.length - 1);
// Set the original array to the new array
stringArray = tempStringArray2;
}
}
}
}
It works for me by using require syntax like this:
$('.eventSlick').slick({
dots: true,
slidesToShow: 3,
slidesToScroll: 1,
autoplay: false,
autoplaySpeed: 2000,
arrows: true,
draggable: false,
prevArrow: '<button type="button" data-role="none" class="slick-prev"><img src="' + require("@/assets/img/icon/Arrow_Left.svg")+'"></button>',
In a SQL CASE clause, the first successfully matched condition is applied and any subsequent matching conditions are ignored.
Or you can just do
[YOUR STRING].Replace('\\', ' ').Replace('/', ' ').Replace('"', ' ').Replace('*', ' ').Replace(':', ' ').Replace('?', ' ').Replace('<', ' ').Replace('>', ' ').Replace('|', ' ').Trim();
Check your migration file, maybe you are using Schema::table, like this:
Schema::table('table_name', function ($table) {
// ...
});
If you want to create a new table you must use Schema::create:
Schema::create('table_name', function ($table) {
// ...
});
Use insert
if you want to insert a new element. insert
will not
overwrite an existing element, and you can verify that there was no
previously exising element:
if ( !myMap.insert( std::make_pair( key, value ) ).second ) {
// Element already present...
}
Use []
if you want to overwrite a possibly existing element:
myMap[ key ] = value;
assert( myMap.find( key )->second == value ); // post-condition
This form will overwrite any existing entry.

ViewPager2
+ FragmentStateAdapter
+ onResume()
(in Fragment)
solve the problem
To detect Fragment
in ViewPager
visible, I'm quite sure that only using setUserVisibleHint
is not enough.
Here is my solution to check if a fragment is visible or invisible. First when launching viewpager, switch between page, go to another activity/fragment/ background/foreground`
public class BaseFragmentHelpLoadDataWhenVisible extends Fragment {
protected boolean mIsVisibleToUser; // you can see this variable may absolutely <=> getUserVisibleHint() but it not. Currently, after many test I find that
/**
* This method will be called when viewpager creates fragment and when we go to this fragment background or another activity or fragment
* NOT called when we switch between each page in ViewPager
*/
@Override
public void onStart() {
super.onStart();
if (mIsVisibleToUser) {
onVisible();
}
}
@Override
public void onStop() {
super.onStop();
if (mIsVisibleToUser) {
onInVisible();
}
}
/**
* This method will called at first time viewpager created and when we switch between each page
* NOT called when we go to background or another activity (fragment) when we go back
*/
@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
mIsVisibleToUser = isVisibleToUser;
if (isResumed()) { // fragment have created
if (mIsVisibleToUser) {
onVisible();
} else {
onInVisible();
}
}
}
public void onVisible() {
Toast.makeText(getActivity(), TAG + "visible", Toast.LENGTH_SHORT).show();
}
public void onInVisible() {
Toast.makeText(getActivity(), TAG + "invisible", Toast.LENGTH_SHORT).show();
}
}
EXPLANATION You can check the logcat below carefully then I think you may know why this solution will work
First launch
Fragment1: setUserVisibleHint: isVisibleToUser=false isResumed=false
Fragment2: setUserVisibleHint: isVisibleToUser=false isResumed=false
Fragment3: setUserVisibleHint: isVisibleToUser=false isResumed=false
Fragment1: setUserVisibleHint: isVisibleToUser=true isResumed=false // AT THIS TIME isVisibleToUser=true but fragment still not created. If you do something with View here, you will receive exception
Fragment1: onCreateView
Fragment1: onStart mIsVisibleToUser=true
Fragment2: onCreateView
Fragment3: onCreateView
Fragment2: onStart mIsVisibleToUser=false
Fragment3: onStart mIsVisibleToUser=false
Go to page2
Fragment1: setUserVisibleHint: isVisibleToUser=false isResumed=true
Fragment2: setUserVisibleHint: isVisibleToUser=true isResumed=true
Go to page3
Fragment2: setUserVisibleHint: isVisibleToUser=false isResumed=true
Fragment3: setUserVisibleHint: isVisibleToUser=true isResumed=true
Go to background:
Fragment1: onStop mIsVisibleToUser=false
Fragment2: onStop mIsVisibleToUser=false
Fragment3: onStop mIsVisibleToUser=true
Go to foreground
Fragment1: onStart mIsVisibleToUser=false
Fragment2: onStart mIsVisibleToUser=false
Fragment3: onStart mIsVisibleToUser=true

According to me we can declare constructor as a private and also we
can get the instance of that class in the subclass by using static method in class in which we declare constructor and then return class object. we class this method from to the sub class
by using classname.method
name bcz it is static method and the we will get the instance of class in which we declare const.
...and don't forget "$region" for the code to work:
$address = "Salzburg";
$address = str_replace(" ", "+", $address);
$region = "Austria";
$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false®ion=$region");
$json = json_decode($json);
$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};
echo $lat."</br>".$long;

There is a system function called ISNUMERIC for SQL 2008 and up. An example:
SELECT myCol
FROM mTable
WHERE ISNUMERIC(myCol)<> 1;
I did a couple of quick tests and also looked further into the docs:
ISNUMERIC returns 1 when the input expression evaluates to a valid numeric data type; otherwise it returns 0.
Which means it is fairly predictable for example
-9879210433
would pass but 987921-0433
does not.
$9879210433
would pass but 9879210$433
does not.
So using this information you can weed out based on the list of valid currency symbols and +

characters.

This website has a simple solution to this with an example that worked for me. The line of code that does the actual leaving of space for the title is the following:
plt.tight_layout(rect=[0, 0, 1, 0.95])
The MOST CORRECT answer to your question is...
#content > div:first-of-type { /* css */ }
This will apply the CSS to the first div that is a direct child of #content (which may or may not be the first child element of #content)
Another option:
#content > div:nth-of-type(1) { /* css */ }
Here is the formula I'm using

Since this appeared to be a breaking change introduced in version 10 of pip, I downgraded to a compatible version:
pip install 'pip<10'
This command tells pip to install a version of the module lower than version 10. Do this in a virutalenv so you don't screw up your site installation of Python.
You may try using this
<?php
$json = json_decode(file_get_contents('./prod.api.pvp.net/api/lol/euw/v1.1/game/by-summoner/20986461/recent?api_key=*key*'));
print_r($json);
?>
The "./" allows to search url from current directory. You may use

Here is a Python(3) helper library class that I use to simplify file I/O:
import os
# handle files using a callback method, prevents repetition
def _FileIO__file_handler(file_path, mode, callback = lambda f: None):
f = open(file_path, mode)
try:
return callback(f)
except Exception as e:
raise IOError("Failed to %s file" % ["write to", "read from"][mode.lower() in "r rb r+".split(" ")])
finally:
f.close()
class FileIO:
# return the contents of a file
def read(file_path, mode = "r"):
return __file_handler(file_path, mode, lambda rf: rf.read())
# get the lines of a file
def lines(file_path, mode = "r", filter_fn = lambda line: len(line) > 0):
return [line for line in FileIO.read(file_path, mode).strip().split("\n") if filter_fn(line)]
# create or update a file (NOTE: can also be used to replace a file's original content)
def write(file_path, new_content, mode = "w"):
return __file_handler(file_path, mode, lambda wf: wf.write(new_content))
# delete a file (if it exists)
def delete(file_path):
return os.remove() if os.path.isfile(file_path) else None
You would then use the FileIO.lines
function, like this:
file_ext_lines = FileIO.lines("./path/to/file.ext"):
for i, line in enumerate(file_ext_lines):
print("Line {}: {}".format(i + 1, line))
Remember that the mode
("r"
by default) and filter_fn
(checks for empty lines by default) parameters are optional.
You could even remove the read
, write
and delete
methods and just leave the FileIO.lines
, or even turn it into a separate method called read_lines
.
Python's standard library has json
and urllib2
modules.
import json
import urllib2
data = json.load(urllib2.urlopen('http://someurl/path/to/json'))
You can use a FileReader
object to read text file here is example code:
<div id="page-wrapper">
<h1>Text File Reader</h1>
<div>
Select a text file:
<input type="file" id="fileInput">
</div>
<pre id="fileDisplayArea"><pre>
</div>
<script>
window.onload = function() {
var fileInput = document.getElementById('fileInput');
var fileDisplayArea = document.getElementById('fileDisplayArea');
fileInput.addEventListener('change', function(e) {
var file = fileInput.files[0];
var textType = /text.*/;
if (file.type.match(textType)) {
var reader = new FileReader();
reader.onload = function(e) {
fileDisplayArea.innerText = reader.result;
}
reader.readAsText(file);
} else {
fileDisplayArea.innerText = "File not supported!"
}
});
}
</script>
Here is the codepen demo
If you have a fixed file to read every time your application load then you can use this code :
<script>
var fileDisplayArea = document.getElementById('fileDisplayArea');
function readTextFile(file)
{
var rawFile = new XMLHttpRequest();
rawFile.open("GET", file, false);
rawFile.onreadystatechange = function ()
{
if(rawFile.readyState === 4)
{
if(rawFile.status === 200 || rawFile.status == 0)
{
var allText = rawFile.responseText;
fileDisplayArea.innerText = allText
}
}
}
rawFile.send(null);
}
readTextFile("file:///C:/your/path/to/file.txt");
</script>
I just want to give the solution that I came up with that handles all cases presented in this post that I derived from Vasek and devconsole. This solution also handles the special case when the phone is rotated more than once while fragments aren't visible.
Here is were I store the bundle for later use since onCreate and onSaveInstanceState are the only calls that are made when the fragment isn't visible
MyObject myObject;
private Bundle savedState = null;
private boolean createdStateInDestroyView;
private static final String SAVED_BUNDLE_TAG = "saved_bundle";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
savedState = savedInstanceState.getBundle(SAVED_BUNDLE_TAG);
}
}
Since destroyView isn't called in the special rotation situation we can be certain that if it creates the state we should use it.
@Override
public void onDestroyView() {
super.onDestroyView();
savedState = saveState();
createdStateInDestroyView = true;
myObject = null;
}
This part would be the same.
private Bundle saveState() {
Bundle state = new Bundle();
state.putSerializable(SAVED_BUNDLE_TAG, myObject);
return state;
}
Now here is the tricky part. In my onActivityCreated method I instantiate the "myObject" variable but the rotation happens onActivity and onCreateView don't get called. Therefor, myObject will be null in this situation when the orientation rotates more than once. I get around this by reusing the same bundle that was saved in onCreate as the out going bundle.
@Override
public void onSaveInstanceState(Bundle outState) {
if (myObject == null) {
outState.putBundle(SAVED_BUNDLE_TAG, savedState);
} else {
outState.putBundle(SAVED_BUNDLE_TAG, createdStateInDestroyView ? savedState : saveState());
}
createdStateInDestroyView = false;
super.onSaveInstanceState(outState);
}
Now wherever you want to restore the state just use the savedState bundle
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
...
if(savedState != null) {
myObject = (MyObject) savedState.getSerializable(SAVED_BUNDLE_TAG);
}
...
}

On *nix check nm. On windows use the program Dependency Walker
It's as simple as:
>>> lists = [[1, 2], [3, 4]]
>>> np.array(lists)
array([[1, 2],
[3, 4]])
Another approach through flipping array to get direct value.
Snippet
$array = [ 'Name1' => 'John', 'Name2' => 'Jane', 'Name3' => 'Jonny' ];
$val = array_rand(array_flip($array));
array_rand
return key not value. So, we're flipping value as key.
Note: PHP key alway be an unique key, so when array is flipped, duplicate value as a key will be overwritten.
If you're looking at using this for relative timing (for example for games or animation) I'd rather use CACurrentMediaTime()
double CurrentTime = CACurrentMediaTime();
Which is the recommended way; NSDate
draws from the networked synch-clock and will occasionally hiccup when re-synching it against the network.
It returns the current absolute time, in seconds.
If you want only the decimal part (often used when syncing animations),
let ct = CACurrentMediaTime().truncatingRemainder(dividingBy: 1)
Most Markdown parsers don't support tables without headers. That means the separation line for headers is mandatory.
PHP Markdown Extra "second line contains a mandatory separator line between the headers and the content"
RDiscount Uses PHP Markdown Extra syntax.
simple_tables
and multiline_tables
extensions)If you're able to change the CSS of the HTML output you can however leverage the :empty
pseudo class to hide an empty header and make it look like there is no header at all.
I had twoo users: one that had the sysadmin role, the other one (the problematic one) didn't.
So I logged in with the other user(you can create a new one) and checked the ckeck box 'sysadmin' from: Security --> Logins --> Right ckick on your SQL user name --> Properties --> Server Roles --> make sure that the 'sysadmin' checkbox has the check mark. Press OK and try connecting with the newly checked user.

You seem to be doing file name comparisons, so I would just add that OrdinalIgnoreCase
is closest to what NTFS does (it's not exactly the same, but it's closer than InvariantCultureIgnoreCase
)
When you get frustrated trying this:
CASE WHEN last_name IS NULL THEN '' ELSE ' '+last_name END
Try this one instead:
CASE LEN(ISNULL(last_Name,''))
WHEN 0 THEN ''
ELSE ' ' + last_name
END AS newlastName
LEN(ISNULL(last_Name,''))
measures the number of characters in that column, which will be zero whether it's empty, or NULL, therefore WHEN 0 THEN
will evaluate to true and return the '' as expected.
I hope this is a helpful alternative.
I have included this test case for sql server 2008 and above:
DECLARE @last_Name varchar(50) = NULL
SELECT
CASE LEN(ISNULL(@last_Name,''))
WHEN 0 THEN ''
ELSE 'A ' + @last_name
END AS newlastName
SET @last_Name = 'LastName'
SELECT
CASE LEN(ISNULL(@last_Name,''))
WHEN 0 THEN ''
ELSE 'A ' + @last_name
END AS newlastName
Just loop through all the <strong>
tags and use next_sibling
to get what you want. Like this:
for strong_tag in soup.find_all('strong'):
print(strong_tag.text, strong_tag.next_sibling)
Demo:
from bs4 import BeautifulSoup
html = '''
<p>
<strong class="offender">YOB:</strong> 1987<br />
<strong class="offender">RACE:</strong> WHITE<br />
<strong class="offender">GENDER:</strong> FEMALE<br />
<strong class="offender">HEIGHT:</strong> 5'05''<br />
<strong class="offender">WEIGHT:</strong> 118<br />
<strong class="offender">EYE COLOR:</strong> GREEN<br />
<strong class="offender">HAIR COLOR:</strong> BROWN<br />
</p>
'''
soup = BeautifulSoup(html)
for strong_tag in soup.find_all('strong'):
print(strong_tag.text, strong_tag.next_sibling)
This gives you:
YOB: 1987
RACE: WHITE
GENDER: FEMALE
HEIGHT: 5'05''
WEIGHT: 118
EYE COLOR: GREEN
HAIR COLOR: BROWN
The title attribute also works well with other html elements, for example a link...
<a title="hover text" ng-href="{{getUrl()}}"> download link
</a>
You can use the Console.SetCursorPosition
function to go to a specific line number.
Than you can use this function to clear the line
public static void ClearCurrentConsoleLine()
{
int currentLineCursor = Console.CursorTop;
Console.SetCursorPosition(0, Console.CursorTop);
Console.Write(new string(' ', Console.WindowWidth));
Console.SetCursorPosition(0, currentLineCursor);
}
Console.WriteLine("Test");
Console.SetCursorPosition(0, Console.CursorTop - 1);
ClearCurrentConsoleLine();
Try =Year(Now())
and format the cell as General

here you can find an implementation :
def __uniqueid__():
"""
generate unique id with length 17 to 21.
ensure uniqueness even with daylight savings events (clocks adjusted one-hour backward).
if you generate 1 million ids per second during 100 years, you will generate
2*25 (approx sec per year) * 10**6 (1 million id per sec) * 100 (years) = 5 * 10**9 unique ids.
with 17 digits (radix 16) id, you can represent 16**17 = 295147905179352825856 ids (around 2.9 * 10**20).
In fact, as we need far less than that, we agree that the format used to represent id (seed + timestamp reversed)
do not cover all numbers that could be represented with 35 digits (radix 16).
if you generate 1 million id per second with this algorithm, it will increase the seed by less than 2**12 per hour
so if a DST occurs and backward one hour, we need to ensure to generate unique id for twice times for the same period.
the seed must be at least 1 to 2**13 range. if we want to ensure uniqueness for two hours (100% contingency), we need
a seed for 1 to 2**14 range. that's what we have with this algorithm. You have to increment seed_range_bits if you
move your machine by airplane to another time zone or if you have a glucky wallet and use a computer that can generate
more than 1 million ids per second.
one word about predictability : This algorithm is absolutely NOT designed to generate unpredictable unique id.
you can add a sha-1 or sha-256 digest step at the end of this algorithm but you will loose uniqueness and enter to collision probability world.
hash algorithms ensure that for same id generated here, you will have the same hash but for two differents id (a pair of ids), it is
possible to have the same hash with a very little probability. You would certainly take an option on a bijective function that maps
35 digits (or more) number to 35 digits (or more) number based on cipher block and secret key. read paper on breaking PRNG algorithms
in order to be convinced that problems could occur as soon as you use random library :)
1 million id per second ?... on a Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz, you get :

You are really asking a couple of questions here:
1) Why does the price of SSL certificates vary so much
2) Where can I get good, cheap SSL certificates?
The first question is a good one. For example, the type of SSL certificate you buy is important. Many SSL certificates are domain verified only - that is, the company issuing the certificate only validate that you own the domain. They don't validate your identity, so people visiting your site might know that the domain has a SSL certificate, but that doesn't mean the person behing the website isn't a scammer or phisher, for example. This is why the Verisign solution is much more expensive - you are getting a cert that not only secures your site, but validates the identity of the owner of the site (well, that's the claim).
You can read more on this subject here
For your second question, I can personally recommend RapidSSL. I've bought several certificates from them in the past and they are, well, rapid. However, you should always do your research first. A company based in France might be better for you to deal with as you can get support in your local hours, etc.
Another alternative, combining several of the answers.
zip(*sorted(zip(Y,X)))[1]
In order to work for python3:
list(zip(*sorted(zip(B,A))))[1]
In the recent Git, you can add -r
/--rebase
on pull
command to rebase your current branch on top of the upstream branch after fetching. The warning should disappear, but there is a risk that you'll get some conflicts which you'll need to solve.
Alternatively you can checkout different branch with force, then go back to master
again, e.g.:
git checkout origin/master -f
git checkout master -f
Then pull it again as usual:
git pull origin master
Using this method can save you time from stashing (git stash
) and potential permission issues, reseting files (git reset HEAD --hard
), removing files (git clean -fd
), etc. Also the above it's easier to remember.
Actually, this is much more simple. You need only two things.
First, you need to find four orthogonal distances from the circle centre to each line of the rectangle. Then your circle will not intersect the rectangle if any three of them are larger than the circle radius.
Second, you need to find the distance between the circle centre and the rectangle centre, then you circle will not be inside of the rectangle if the distance is larger than a half of the rectangle diagonal length.
Good luck!
For this issue need to add the partition for date column values, If last partition 20201231245959, then inserting the 20210110245959 values, this issue will occurs.

You can use dateutil.parser.parse
(install with python -m pip install python-dateutil
) to parse strings into datetime objects.
dateutil.parser.parse
will attempt to guess the format of your string, if you know the exact format in advance then you can use datetime.strptime
which you supply a format string to (see Brent Washburne's answer).
from dateutil.parser import parse
a = "2012-10-09T19:00:55Z"
b = parse(a)
print(b.weekday())
# 1 (equal to a Tuesday)
This is one way of solving the same, declare a JavaScript function like this
<script>
function Exit() {
var x=confirm('Are You sure want to exit:');
if(x) window.close();
}
</script>
Add the following line to the HTML to call the function using a <button>
<button name='closeIt' onClick="Exit()" >Click to exit </Button>
No need to increase the MaxConnections & InitialConnections. Just close your connections after after doing your work. For example if you are creating connection:
try {
connection = DriverManager.getConnection(
"jdbc:postgresql://127.0.0.1/"+dbname,user,pass);
} catch (SQLException e) {
e.printStackTrace();
return;
}
After doing your work close connection:
try {
connection.commit();
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}
Here's the solution I used in Kotlin

{
val secondsUntilFinished : Long =
Math.ceil(millisUntilFinished.toDouble()/1000).toLong()
val timeString = "${TimeUnit.SECONDS.toMinutes(secondsUntilFinished)}:" +
"%02d".format(TimeUnit.SECONDS.toSeconds(secondsUntilFinished))
Log.d(TAG, ":startTimer::CountDownTimer:millisUntilFinished = $ttlseconds")
Log.d(TAG, ":startTimer::CountDownTimer:millisUntilFinished = $millisUntilFinished")
}
@SuppressLint("SetTextI18n")
override fun onFinish()
{
timerTxtVw.text = "0:00"

}
There is a correct way of uploading a file with its name with Retrofit 2, without any hack:
Define API interface:
@Multipart
@POST("uploadAttachment")
Call<MyResponse> uploadAttachment(@Part MultipartBody.Part filePart);
// You can add other parameters too
Upload file like this:
File file = // initialize file here
MultipartBody.Part filePart = MultipartBody.Part.createFormData("file", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));
Call<MyResponse> call = api.uploadAttachment(filePart);
This demonstrates only file uploading, you can also add other parameters in the same method with @Part
annotation.
You just need to post the form data to the insert php file function, see below :)
class DbConnect
{
// Database login vars
private $dbHostname = '';
private $dbDatabase = '';
private $dbUsername = '';
private $dbPassword = '';
public $db = null;
public function connect()
{
try
{
$this->db = new PDO("mysql:host=".$this->dbHostname.";dbname=".$this->dbDatabase, $this->dbUsername, $this->dbPassword);
$this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e)
{
echo "It seems there was an error. Please refresh your browser and try again. ".$e->getMessage();
}
}
public function store($email)
{
$stm = $this->db->prepare('INSERT INTO subscribers (email) VALUES ?');
$stm->bindValue(1, $email);
return $stm->execute();
}
}
My suggestion is the log file should always be logged above the root context of the webApp, so in case we redeploy the webApp, we don't want to override the existing log files.
There are two ways(actually there are more) that you could do this.
1. using lxml
pip install lxml
from lxml import etree, objectify
from lxml.etree import XMLSyntaxError
def xml_validator(some_xml_string, xsd_file='/path/to/my_schema_file.xsd'):
try:
schema = etree.XMLSchema(file=xsd_file)
parser = objectify.makeparser(schema=schema)
objectify.fromstring(some_xml_string, parser)
print "YEAH!, my xml file has validated"
except XMLSyntaxError:
#handle exception here
print "Oh NO!, my xml file does not validate"
pass
xml_file = open('my_xml_file.xml', 'r')
xml_string = xml_file.read()
xml_file.close()
xml_validator(xml_string, '/path/to/my_schema_file.xsd')
>> xmllint --format --pretty 1 --load-trace --debug --schema /path/to/my_schema_file.xsd /path/to/my_xml_file.xml
A temporary work around would be to set the path from the terminal itself. Worked for me after that. Running as administrator also works. Both M2 and M2_HOME are already set as system variables in my case.
No, the Compare function will return either 1, 0, or -1. 0 when the two values are equal, -1 and 1 mean less than and greater than, I believe in that order, but I often mix them up.
z = list(zip(*tuple_list))
z[1][z[0].index('persimon')]
If you start having to mentally count off the parameters in the signature and match them to the call, then it is time to refactor!
r stands for a raw string, so things like \ will be automatically escaped by Python.
Normally, if you wanted your pattern to include something like a backslash you'd need to escape it with another backslash. raw strings eliminate this problem.
In your case, it does not matter much but it's a good habit to get into early otherwise something like \b will bite you in the behind if you are not careful (will be interpreted as backspace character instead of word boundary)
As per re.match vs re.search here's an example that will clarify it for you:
>>> import re
>>> testString = 'hello world'
>>> re.match('hello', testString)
<_sre.SRE_Match object at 0x015920C8>
>>> re.search('hello', testString)
<_sre.SRE_Match object at 0x02405560>
>>> re.match('world', testString)
>>> re.search('world', testString)
<_sre.SRE_Match object at 0x015920C8>
So search will find a match anywhere, match will only start at the beginning
My favorite rendering of the procedures list of the current database: name, parameters list, comment
SELECT specific_name AS name, param_list AS params, `comment`
FROM mysql.proc
WHERE db = DATABASE()
AND type = 'PROCEDURE';
Add returns for functions:
SELECT specific_name AS name, param_list AS params, `returns`, `comment`
FROM mysql.proc
WHERE db = DATABASE()
AND type = 'FUNCTION';
Just enter plt.hold(False)
before the first plt.plot, and you can stick to your original code.
When we insert any line break with a programming language the char code for this is "\n". php does output that but html can't display that due to htmls line break is
. so easy way to do this job is replacing all the "\n" with "
". so the code should be
str_replace("\n","<br/>",$str);
after adding this code you wont have to use pre tag for all the output oparation.

You can simply put "." the dot sign. I've had a cmd application that was requiring the path and I was already in the needed directory and I used the dot symbol.
Hope it helps.
Problem Solved,
I edited the file /etc/postfix/master.cf
and commented
-o smtpd_relay_restrictions=permit_sasl_authenticated,reject
and changed the line from
-o smtpd_tls_security_level=encrypt
to
-o smtpd_tls_security_level=may
And worked on fine
You can convert Map
to JSON
using Jackson
as follows:
Map<String,Object> map = new HashMap<>();
//You can convert any Object.
String[] value1 = new String[] { "value11", "value12", "value13" };
String[] value2 = new String[] { "value21", "value22", "value23" };
map.put("key1", value1);
map.put("key2", value2);
map.put("key3","string1");
map.put("key4","string2");
String json = new ObjectMapper().writeValueAsString(map);
System.out.println(json);

If you are using JSONObject
library, you can convert map to JSON
as follows:
Map<String, Object> map = new HashMap<>();
// Convert a map having list of values.
String[] value1 = new String[] { "value11", "value12", "value13" };
String[] value2 = new String[] { "value21", "value22", "value23" };
map.put("key1", value1);
map.put("key2", value2);
JSONObject json = new JSONObject(map);
System.out.println(json);
Maven Dependencies for JSONObject
:
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20140107</version>
</dependency>
Hope this will help. Happy coding.
To make it easier to invoke MySQL programs, you can add the path name of the MySQL bin directory to your Windows system PATH environment variable:
On the Windows desktop, right-click the My Computer icon, and select Properties.
Next select the Advanced tab from the System Properties menu that appears, and click the Environment Variables button.
Under System Variables, select Path, and then click the Edit button. The Edit System Variable dialogue should appear.
Place your cursor at the end of the text appearing in the space marked Variable Value. (Use the End key to ensure that your cursor is positioned at the very end of the text in this space.) Then enter the complete path name of your MySQL bin directory (for example, C:\Program Files\MySQL\MySQL Server 8.0\bin
).
Open a different terminal and if you are using root as user run mysql -u root -p
else use the a different username you created.
To make a vertical line, just use a rectangle with width of 1dp:
<shape>
<size
android:width="1dp"
android:height="16dp" />
<solid
android:color="#c8cdd2" />
</shape>
Don't use stroke
, use solid
(which is the "fill" color) to specify the color of the line.
Cast one of the integers/both of the integer to float to force the operation to be done with floating point Math. Otherwise integer Math is always preferred. So:
1. v = (float)s / t;
2. v = (float)s / (float)t;
.
character as a wildcard to match any single character.Example regex: a.c
abc // match
a c // match
azc // match
ac // no match
abbc // no match
[]
to match any characters in a set.\w
to match any single alphanumeric character: 0-9
, a-z
, A-Z
, and _
(underscore).\d
to match any single digit.\s
to match any single whitespace character.Example 1 regex: a[bcd]c
abc // match
acc // match
adc // match
ac // no match
abbc // no match
Example 2 regex: a[0-7]c
a0c // match
a3c // match
a7c // match
a8c // no match
ac // no match
a55c // no match
Use the hat in square brackets [^]
to match any single character except for any of the characters that come after the hat ^
.
Example regex: a[^abc]c
aac // no match
abc // no match
acc // no match
a c // match
azc // match
ac // no match
azzc // no match
(Don't confuse the ^
here in [^]
with its other usage as the start of line character: ^
= line start, $
= line end.)
Use the optional character ?
after any character to specify zero or one occurrence of that character. Thus, you would use .?
to match any single character optionally.
Example regex: a.?c
abc // match
a c // match
azc // match
ac // match
abbc // no match

I managed to create a simple console "hello world" with QT Creator
used creator 2.4.1 and QT 4.8.0 on windows 7
two ways to do this
Plain C++
do the following
or
QT Console
example: for QT console "hello world"
file - new file project 'project name '
other projects - QT Console Application
Targets select 'Desktop'
project management - next
code:
#include <QtCore/QCoreApplication>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
cout<<" hello world";
return a.exec();
}
ctrl -R to run
compilers used for above MSVC 2010 (QT SDK) , and minGW(QT SDK)
hope this helps someone
As I have just started to use QT recently and also searched the Www for info and examples to get started with simple examples still searching...
First of all, that's a forward slash. And no, you can't have any in regexes unless you escape them. To escape them, put a backslash (\
) in front of it.

How do I create a new column with Groupby().Sum()?
There are two ways - one straightforward and the other slightly more interesting.
GroupBy.transform()
with 'sum'
@Ed Chum's answer can be simplified, a bit. Call DataFrame.groupby
rather than Series.groupby
. This results in simpler syntax.
# The setup.
df[['Date', 'Data3']]
Date Data3
0 2015-05-08 5
1 2015-05-07 8
2 2015-05-06 6
3 2015-05-05 1
4 2015-05-08 50
5 2015-05-07 100
6 2015-05-06 60
7 2015-05-05 120
df.groupby('Date')['Data3'].transform('sum')
0 55
1 108
2 66
3 121
4 55
5 108
6 66
7 121
Name: Data3, dtype: int64
It's a tad faster,
df2 = pd.concat([df] * 12345)
%timeit df2['Data3'].groupby(df['Date']).transform('sum')
%timeit df2.groupby('Date')['Data3'].transform('sum')
10.4 ms ± 367 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
8.58 ms ± 559 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
GroupBy.sum()
+ Series.map()
I stumbled upon an interesting idiosyncrasy in the API. From what I tell, you can reproduce this on any major version over 0.20 (I tested this on 0.23 and 0.24). It seems like you consistently can shave off a few milliseconds of the time taken by transform
if you instead use a direct function of GroupBy
and broadcast it using map
:
df.Date.map(df.groupby('Date')['Data3'].sum())
0 55
1 108
2 66
3 121
4 55
5 108
6 66
7 121
Name: Date, dtype: int64
Compare with
df.groupby('Date')['Data3'].transform('sum')
0 55
1 108
2 66
3 121
4 55
5 108
6 66
7 121
Name: Data3, dtype: int64
My tests show that map
is a bit faster if you can afford to use the direct GroupBy
function (such as mean
, min
, max
, first
, etc). It is more or less faster for most general situations upto around ~200 thousand records. After that, the performance really depends on the data.
(Left: v0.23, Right: v0.24)
Nice alternative to know, and better if you have smaller frames with smaller numbers of groups. . . but I would recommend transform
as a first choice. Thought this was worth sharing anyway.
Benchmarking code, for reference:
import perfplot
perfplot.show(
setup=lambda n: pd.DataFrame({'A': np.random.choice(n//10, n), 'B': np.ones(n)}),
kernels=[
lambda df: df.groupby('A')['B'].transform('sum'),
lambda df: df.A.map(df.groupby('A')['B'].sum()),
],
labels=['GroupBy.transform', 'GroupBy.sum + map'],
n_range=[2**k for k in range(5, 20)],
xlabel='N',
logy=True,
logx=True
)
Try to add ReactiveFormsModule in your component as well.
import { FormGroup, FormArray, FormBuilder,
Validators,ReactiveFormsModule } from '@angular/forms';
$ gcc test.c -o testc $ file testc testc: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped $ ldd testc linux-vdso.so.1 => (0x00007fff227ff000) libc.so.6 => /lib64/libc.so.6 (0x000000391f000000) /lib64/ld-linux-x86-64.so.2 (0x000000391ec00000) $ gcc -m32 test.c -o testc $ file testc testc: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped $ ldd testc linux-gate.so.1 => (0x009aa000) libc.so.6 => /lib/libc.so.6 (0x00780000) /lib/ld-linux.so.2 (0x0075b000)
In short: use the -m32
flag to compile a 32-bit binary.
Also, make sure that you have the 32-bit versions of all required libraries installed (in my case all I needed on Fedora was glibc-devel.i386)
Try:
document.getElementById("foo").onclick = function (){alert('foo');};
try this
@Html.DropDownListFor(model => model.UserName, new List<SelectListItem>
{ new SelectListItem{Text="Active", Value="True",Selected =true },
new SelectListItem{Text="Deactive", Value="False"}})
A Kotlin extension + some padding around the drawable
fun TextView.addDrawable(drawable: Int) {
val imgDrawable = ContextCompat.getDrawable(context, drawable)
compoundDrawablePadding = 32
setCompoundDrawablesWithIntrinsicBounds(imgDrawable, null, null, null)
}
It's platform-specific. But you can cast it to a known type.
printf("%lld\n", (long long) time(NULL));
Prerequisite:
Your APK needs to be signed by system as correctly pointed out earlier. One way to achieve that is building the AOSP image yourself and adding the source code into the build.
Code:
Once installed as a system app, you can use the package manager methods to install and uninstall an APK as following:
Install:
public boolean install(final String apkPath, final Context context) {
Log.d(TAG, "Installing apk at " + apkPath);
try {
final Uri apkUri = Uri.fromFile(new File(apkPath));
final String installerPackageName = "MyInstaller";
context.getPackageManager().installPackage(apkUri, installObserver, PackageManager.INSTALL_REPLACE_EXISTING, installerPackageName);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
Uninstall:
public boolean uninstall(final String packageName, final Context context) {
Log.d(TAG, "Uninstalling package " + packageName);
try {
context.getPackageManager().deletePackage(packageName, deleteObserver, PackageManager.DELETE_ALL_USERS);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
To have a callback once your APK is installed/uninstalled you can use this:
/**
* Callback after a package was installed be it success or failure.
*/
private class InstallObserver implements IPackageInstallObserver {
@Override
public void packageInstalled(String packageName, int returnCode) throws RemoteException {
if (packageName != null) {
Log.d(TAG, "Successfully installed package " + packageName);
callback.onAppInstalled(true, packageName);
} else {
Log.e(TAG, "Failed to install package.");
callback.onAppInstalled(false, null);
}
}
@Override
public IBinder asBinder() {
return null;
}
}
/**
* Callback after a package was deleted be it success or failure.
*/
private class DeleteObserver implements IPackageDeleteObserver {
@Override
public void packageDeleted(String packageName, int returnCode) throws RemoteException {
if (packageName != null) {
Log.d(TAG, "Successfully uninstalled package " + packageName);
callback.onAppUninstalled(true, packageName);
} else {
Log.e(TAG, "Failed to uninstall package.");
callback.onAppUninstalled(false, null);
}
}
@Override
public IBinder asBinder() {
return null;
}
}
/**
* Callback to give the flow back to the calling class.
*/
public interface InstallerCallback {
void onAppInstalled(final boolean success, final String packageName);
void onAppUninstalled(final boolean success, final String packageName);
}
REST is just a software architecture style for exposing resources.
A typical REST call to return information about customer 34456 could look like:
http://example.com/customer/34456
Have a look at the IBM tutorial for REST web services
select View-->DBMS Output in menu and
Try it this way,
ArrayList<String> List_Of_Array = new ArrayList<String>();
List_Of_Array.add("A");
List_Of_Array.add("B");
List_Of_Array.add("C");
List_Of_Array.add("D");
List_Of_Array.add("E");
List_Of_Array.add("F");
List_Of_Array.add("G");
List_Of_Array.add("H");
int i[] = {5,3,1};
for (int j = 0; j < i.length; j++) {
List_Of_Array.remove(i[j]);
}
I had the same issue recently on my test server. After searching for reasons this might be happening and testing the solutions I found here, I recalled that I had clicked the "Stop this page from creating pop-ups" option a few hours before when the script I was working on was wildly popping up alerts.
The solution was as simple as closing the tab and opening a fresh one!
