Start Activity2 with startActivityForResult
and use setResult
method for sending data back from Activity2 to Activity1. In Activity1 you will need to override onActivityResult
for updating TextView
with EditText
data from Activity2.
For example:
In Activity1, start Activity2 as:
Intent i = new Intent(this, Activity2.class);
startActivityForResult(i, 1);
In Activity2, use setResult
for sending data back:
Intent intent = new Intent();
intent.putExtra("editTextValue", "value_here")
setResult(RESULT_OK, intent);
finish();
And in Activity1, receive data with onActivityResult
:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
if(resultCode == RESULT_OK) {
String strEditText = data.getStringExtra("editTextValue");
}
}
}
If you can, also use SharedPreferences for sharing data between Activities.
I have written simple cookieUtils, it has three functions for creating the cookie, reading the cookie and deleting the cookie.
var CookieUtils = {
createCookie: function (name, value, expireTime) {
expireTime = !!expireTime ? expireTime : (15 * 60 * 1000); // Default 15 min
var date = new Date();
date.setTime(date.getTime() + expireTime);
var expires = "; expires=" + date.toGMTString();
document.cookie = name + "=" + value + expires + "; path=/";
},
getCookie: function (name) {
var value = "; " + document.cookie;
var parts = value.split("; " + name + "=");
if (parts.length == 2) {
return parts.pop().split(";").shift();
}
},
deleteCookie: function(name) {
document.cookie = name +'=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;';
}
};
In my case I had the same issue on running from eclipse. Just did the following to resolve it: Right Click the Project --> Mavan --> Update Project.
And it worked!
The characters you are reading on your screen now each have a numerical value. In the ASCII format, for example, the letter 'A' is 65, 'B' is 66, and so on. If you look at a table of characters available in ASCII you will see that it isn't much use for someone who wishes to write something in Mandarin, Arabic, or Japanese. For characters / words from those languages to be displayed we needed another system of encoding them to and from numbers stored in computer memory.
UTF-8 is just one of the encoding methods that were invented to implement this requirement. It lets you write text in all kinds of languages, so French accents will appear perfectly fine, as will text like this
???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????
If you copy and paste the above text into notepad and then try to save the file as ANSI (another format) you will receive a warning that saving in this format will lose some of the formatting. Accept it, then re-load the text file and you'll see something like this
???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????
In MariaDB you can use
SELECT NOW(4);
To get milisecs. See here, too.
pgrep
can get you all of the child PIDs of a parent process. As mentioned earlier $$
is the current scripts PID. So, if you want a script that cleans up after itself, this should do the trick:
trap 'kill $( pgrep -P $$ | tr "\n" " " )' SIGINT SIGTERM EXIT
Modify to suit your specifics, or make more generic as needed:
Private Sub CopyItOver()
Set NewBook = Workbooks.Add
Workbooks("Whatever.xlsx").Worksheets("output").Range("A1:K10").Copy
NewBook.Worksheets("Sheet1").Range("A1").PasteSpecial (xlPasteValues)
NewBook.SaveAs FileName:=NewBook.Worksheets("Sheet1").Range("E3").Value
End Sub
Best answer I found
To get the remote ip address the quickest way possible. You must have to use a downloader, or create a server on your computer.
The downsides to using this simple code: (which is recommended) is that it will take 3-5 seconds to get your Remote IP Address because the WebClient when initialized always takes 3-5 seconds to check for your proxy settings.
public static string GetIP()
{
string externalIP = "";
externalIP = new WebClient().DownloadString("http://checkip.dyndns.org/");
externalIP = (new Regex(@"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"))
.Matches(externalIP)[0].ToString();
return externalIP;
}
Here is how I fixed it.. (first time still takes 3-5 seconds) but after that it will always get your Remote IP Address in 0-2 seconds depending on your connection.
public static WebClient webclient = new WebClient();
public static string GetIP()
{
string externalIP = "";
externalIP = webclient.DownloadString("http://checkip.dyndns.org/");
externalIP = (new Regex(@"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"))
.Matches(externalIP)[0].ToString();
return externalIP;
}
An entity manager can only be injected in classes running inside a transaction. In other words, it can only be injected in a EJB. Other classe must use an EntityManagerFactory to create and destroy an EntityManager.
Since your TestService is not an EJB, the annotation @PersistenceContext is simply ignored. Not only that, in JavaEE 5, it's not possible to inject an EntityManager nor an EntityManagerFactory in a JAX-RS Service. You have to go with a JavaEE 6 server (JBoss 6, Glassfish 3, etc).
Here's an example of injecting an EntityManagerFactory:
package com.test.service;
import java.util.*;
import javax.persistence.*;
import javax.ws.rs.*;
@Path("/service")
public class TestService {
@PersistenceUnit(unitName = "test")
private EntityManagerFactory entityManagerFactory;
@GET
@Path("/get")
@Produces("application/json")
public List get() {
EntityManager entityManager = entityManagerFactory.createEntityManager();
try {
return entityManager.createQuery("from TestEntity").getResultList();
} finally {
entityManager.close();
}
}
}
The easiest way to go here is to declare your service as a EJB 3.1, assuming you're using a JavaEE 6 server.

Ran into this problem when using F12 to try and go to a method definition.
All of the mentioned items (except the /resetuserdata
- which I didn't try because it would be a pain to recover from) didn't work.
What did work for me:
From a Command Prompt, go to the folder for your solution and run the following code (this deletes ALL bin and obj folders in your solution):
FOR /F "tokens=*" %%G IN ('DIR /B /AD /S bin') DO RMDIR /S /Q "%%G"
FOR /F "tokens=*" %%G IN ('DIR /B /AD /S obj') DO RMDIR /S /Q "%%G"
Restart Visual Studio. Opening the solution should take a bit longer as it now rebuilds the obj folders.
After doing this F12 worked!
As a side note, I normally place this in a batch file in my solution's folder, along side the .sln
file. This makes it easy to run later!
You can do :
1) javac -cp /path/to/jar/file Myprogram.java
2) java -cp .:/path/to/jar/file Myprogram
So, lets suppose your current working directory
in terminal is src/Report/
javac -cp src/external/myfile.jar Reporter.java
java -cp .:src/external/myfile.jar Reporter
Take a look here to setup Classpath
var top = $('html').offset().top;
should do it.
edit: this is the negative of $(document).scrollTop()
@kashesandr's solution worked for me but to hide horizontal scrollbar I added one more style for body. here is complete solution:
CSS
<style>
/* prevent layout shifting and hide horizontal scroll */
html {
width: 100vw;
}
body {
overflow-x: hidden;
}
</style>
JS
$(function(){
/**
* For multiple modals.
* Enables scrolling of 1st modal when 2nd modal is closed.
*/
$('.modal').on('hidden.bs.modal', function (event) {
if ($('.modal:visible').length) {
$('body').addClass('modal-open');
}
});
});
JS Only Solution (when 2nd modal opened from 1st modal):
/**
* For multiple modals.
* Enables scrolling of 1st modal when 2nd modal is closed.
*/
$('.modal').on('hidden.bs.modal', function (event) {
if ($('.modal:visible').length) {
$('body').addClass('modal-open');
$('body').css('padding-right', 17);
}
});
To be able to detect unused imports, code or variables, make sure you have this options in tsconfig.json file
"compilerOptions": {
"noUnusedLocals": true,
"noUnusedParameters": true
}
have the typescript compiler installed, ifnot install it with:
npm install -g typescript
and the tslint extension installed in Vcode, this worked for me, but after enabling I notice an increase amount of CPU usage, specially on big projects.
I would also recomend using typescript hero extension for organizing your imports.

psql "sslmode=require host=localhost port=2345 dbname=postgres" --username=some_user

Let v be the starting vertex
Let G be the graph in question
The following is the pseudo code without using queue
Initially label v as visited as you start from v
BFS(G,v)
for all adjacent vertices w of v in G:
if vertex w is not visited:
label w as visited
for all adjacent vertices w of v in G:
recursively call BFS(G,w)
I would try:
self.wordList = list(wordList)
to force it to make a copy instead of referencing the same object.
If you're on unix the latest version (0.8) adds ndk-build. Here's how to add it:
android.ndk {
moduleName "libraw"
}
It expects to find the JNI under 'src/main/jni', otherwise you can define it with:
sourceSets.main {
jni.srcDirs = 'path'
}
As of 28 JAN 2014 with version 0.8 the build is broken on windows, you have to disable the build with:
sourceSets.main {
jni.srcDirs = [] //disable automatic ndk-build call (currently broken for windows)
}
Another function that would help you look at missing data would be df_status from funModeling library
library(funModeling)
iris.2 is the iris dataset with some added NAs.You can replace this with your dataset.
df_status(iris.2)
This will give you the number and percentage of NAs in each column.
As of "ConstraintLayout1.1.0-beta1" you can use percent to define widths & heights.
android:layout_width="0dp"
app:layout_constraintWidth_default="percent"
app:layout_constraintWidth_percent=".4"
This will define the width to be 40% of the width of the screen. A combination of this and guidelines in percent allows you to create any percent-based layout you want.
N=np.floor(np.divide(l,delta))
...
for j in range(N[i]/2):
N[i]/2
will be a float64
but range()
expects an integer. Just cast the call to
for j in range(int(N[i]/2)):
select CustomerName,count(1) from Customers group by CustomerName having count(1) > 1
mysql 5.4 provides a native split function:

What helped for me was to use llvm-gcc
instead:
ln -s $(which llvm-gcc) /usr/local/bin/gcc
If in every li you have only one row of text you can put text indent on li. Like this :
ul {
list-style: disc;
}
ul li {
text-indent: 5px;
}
or
ul {
list-style: disc;
}
ul li {
text-indent: -5px;
}
To obtain a stream of just the names:
$ jq '.[] | select(.location=="Stockholm") | .name' json
produces:
"Donald"
"Walt"
To obtain a stream of corresponding (key name, "name" attribute) pairs, consider:
$ jq -c 'to_entries[]
| select (.value.location == "Stockholm")
| [.key, .value.name]' json
Output:
["FOO","Donald"]
["BAR","Walt"]
There can be an even simpler representation assuming that one has to only test graph algorithms not use them(graph) else where. This can be as a map from vertices to their adjacency lists as shown below :-
#include<bits/stdc++.h>
using namespace std;
/* implement the graph as a map from the integer index as a key to the adjacency list
* of the graph implemented as a vector being the value of each individual key. The
* program will be given a matrix of numbers, the first element of each row will
* represent the head of the adjacency list and the rest of the elements will be the
* list of that element in the graph.
*/
typedef map<int, vector<int> > graphType;
int main(){
graphType graph;
int vertices = 0;
cout << "Please enter the number of vertices in the graph :- " << endl;
cin >> vertices;
if(vertices <= 0){
cout << "The number of vertices in the graph can't be less than or equal to 0." << endl;
exit(0);
}
cout << "Please enter the elements of the graph, as an adjacency list, one row after another. " << endl;
for(int i = 0; i <= vertices; i++){
vector<int> adjList; //the vector corresponding to the adjacency list of each vertex
int key = -1, listValue = -1;
string listString;
getline(cin, listString);
if(i != 0){
istringstream iss(listString);
iss >> key;
iss >> listValue;
if(listValue != -1){
adjList.push_back(listValue);
for(; iss >> listValue; ){
adjList.push_back(listValue);
}
graph.insert(graphType::value_type(key, adjList));
}
else
graph.insert(graphType::value_type(key, adjList));
}
}
//print the elements of the graph
cout << "The graph that you entered :- " << endl;
for(graphType::const_iterator iterator = graph.begin(); iterator != graph.end(); ++iterator){
cout << "Key : " << iterator->first << ", values : ";
vector<int>::const_iterator vectBegIter = iterator->second.begin();
vector<int>::const_iterator vectEndIter = iterator->second.end();
for(; vectBegIter != vectEndIter; ++vectBegIter){
cout << *(vectBegIter) << ", ";
}
cout << endl;
}
}
In case you can't upgrade to Ruby on Rails 2.3.11 (and to expand on douglasr's answer), thread
must be required at the top of boot.rb
. For example:
require 'thread'
# Don't change this file!
# Configure your app in config/environment.rb and config/environments/*.rb
...
You can use find
and ls
to accomplish with this:
find . -type f -exec ls -l {} \; | egrep "Aug 26";
It will find all files in this directory, display useful informations (-l
) and filter the lines with some date you want... It may be a little bit slow, but still useful in some cases.
The aim of having the kernel support different ones is that you can try them out without a reboot; you can then run test workloads through the sytsem, measure performance, and then make that the standard one for your app.
On modern server-grade hardware, only the noop one appears to be at all useful. The others seem slower in my tests.
If you've copied a disk (vmdk file) from one machine to another and need to change a disk's UUID in the copy, you don't need to change the Machine UUID as has been suggested by another answer.
All you need to do is to assign a new UUID to the disk image:
VBoxManage internalcommands sethduuid your-box-disk2.vmdk
UUID changed to: 5d34479f-5597-4b78-a1fa-94e200d16bbb
and then replace the old UUID with the newly generated one in two places in your *.vbox file
<MediaRegistry>
<HardDisks>
<HardDisk uuid="{5d34479f-5597-4b78-a1fa-94e200d16bbb}" location="box-disk2.vmdk" format="VMDK" type="Normal"/>
</HardDisks>
and in
<AttachedDevice type="HardDisk" hotpluggable="false" port="0" device="0">
<Image uuid="{5d34479f-5597-4b78-a1fa-94e200d16bbb}"/>
</AttachedDevice>
It worked for me for VirtualBox ver. 5.1.8 running on Mac OS X El Capitan.
Thank you @user1909426, I can found solution by php artisan list
it will list all command that was used on L4. It can create controller only not Model. I follow this command to generate controller.
php artisan controller:make [Name]Controller
On Laravel 5, the command has changed:
php artisan make:controller [Name]Controller
Note: [Name] name of controller
In stead of parsing JSON you can do like followng:
$.ajax({
..
dataType: 'json' // using json, jquery will make parse for you
});
To access a property of your JSON do following:
data[0].name;
data[0].address;
Why you need data[0]
because data is an array, so to its content retrieve you need data[0]
(first element), which gives you an object {"name":"myName" ,"address": "myAddress" }
.
And to access property of an object rule is:
Object.property
or sometimes
Object["property"] // in some case
So you need
data[0].name
and so on to get what you want.
set dataType: json
then you need to parse them using $.parseJSON()
and to retrieve data like above.
I had a simular problem. I wanted the user to be able to filter "Table3" in a protected worksheet. But the user is not able to edit the table. I accomplished above, using the vba code below:
Range("Table3").Select
Selection.Locked = True
Selection.FormulaHidden = False
ActiveSheet.Protect DrawingObjects:=True, Contents:=True, Scenarios:=True _
, allowfiltering:=True
In the following code I filtered the code using VBA:
Range("Table3[[#Headers],[Aantal4]]").Select
ActiveSheet.ListObjects("Table3").Range.AutoFilter Field:=8, Criteria1:= _
Array("1", "12", "2", "24", "4", "6"), Operator:=xlFilterValues
t = "your string"
Play with the first N characters of a string with
def firstN(s, n=2):
return s[:n]
which is by default equivalent to
t[:2]
As to "how do you calculate" Big O, this is part of Computational complexity theory. For some (many) special cases you may be able to come with some simple heuristics (like multiplying loop counts for nested loops), esp. when all you want is any upper bound estimation, and you do not mind if it is too pessimistic - which I guess is probably what your question is about.
If you really want to answer your question for any algorithm the best you can do is to apply the theory. Besides of simplistic "worst case" analysis I have found Amortized analysis very useful in practice.

The normal name resolution in Python works fine. Why do you need DNSpython for that. Just use socket's getaddrinfo

:

After days trying to find the answer, I finally found
display: table;
There was surprisingly very little information available online about how to actually getting it to work, even here, so on to the "How":
To use this fantastic piece of code, you need to think back to when tables were the only real way to structure HTML, namely the syntax. To get a table with 2 rows and 3 columns, you'd have to do the following:
<table>
<tr>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
</tr>
</table>
Similarly to get CSS to do it, you'd use the following:
<div id="table">
<div class="tr">
<div class="td"></div>
<div class="td"></div>
<div class="td"></div>
</div>
<div class="tr">
<div class="td"></div>
<div class="td"></div>
<div class="td"></div>
</div>
</div>
#table{
display: table;
}
.tr{
display: table-row;
}
.td{
display: table-cell; }
As you can see in the JSFiddle example below, the divs in the 3rd column have no content, yet are respecting the auto height set by the text in the first 2 columns. WIN!
http://jsfiddle.net/blyzz/1djs97yv/1/
It's worth noting that display: table;
does not work in IE6 or 7 (thanks, FelipeAls), so depending on your needs with regards to browser compatibility, this may not be the answer that you are seeking.
This may work as well.
SELECT *
FROM myTable
WHERE CHARINDEX('mall', name) > 0
OR CHARINDEX('mall', description) > 0
If you have same error handling logic for different method handlers, then you would end up with lots of handlers with following code pattern:
if (validation.hasErrors()) {
// do error handling
}
else {
// do the actual business logic
}
Suppose you're creating RESTful services and want to return 400 Bad Request
along with error messages for every validation error case. Then, the error handling part would be same for every single REST endpoint that requires validation. Repeating that very same logic in every single handler is not so DRYish!
One way to solve this problem is to drop the immediate BindingResult
after each To-Be-Validated bean. Now, your handler would be like this:
@RequestMapping(...)
public Something doStuff(@Valid Somebean bean) {
// do the actual business logic
// Just the else part!
}
This way, if the bound bean was not valid, a MethodArgumentNotValidException
will be thrown by Spring. You can define a ControllerAdvice
that handles this exception with that same error handling logic:
@ControllerAdvice
public class ErrorHandlingControllerAdvice {
@ExceptionHandler(MethodArgumentNotValidException.class)
public SomeErrorBean handleValidationError(MethodArgumentNotValidException ex) {
// do error handling
// Just the if part!
}
}
You still can examine the underlying BindingResult
using getBindingResult
method of MethodArgumentNotValidException
.
Try this..
If jQuery is available, angular.element is an alias for the jQuery function.
var app = angular.module('myApp',[]);
app.controller('Ctrl', function($scope) {

};
});
<div id='div1'>Text</div>

You can use these to factor out code common to all tests in the test suite.
If you have a lot of repeated code in your tests, you can make them shorter by moving this code to setUp/tearDown.
You might use this for creating test data (e.g. setting up fakes/mocks), or stubbing out functions with fakes.
If you're doing integration testing, you can use check environmental pre-conditions in setUp, and skip the test if something isn't set up properly.
For example:
class TurretTest(unittest.TestCase):
def setUp(self):
self.turret_factory = TurretFactory()
self.turret = self.turret_factory.CreateTurret()
def test_turret_is_on_by_default(self):
self.assertEquals(True, self.turret.is_on())
def test_turret_turns_can_be_turned_off(self):
self.turret.turn_off()
self.assertEquals(False, self.turret.is_on())
An alternative to the accepted answer that fits in the first line:
#!/bin/bash -e

Just thought I'd toss in my $0.02. I tend to declare this:
template< typename T, size_t N >
std::vector<T> makeVector( const T (&data)[N] )
{
return std::vector<T>(data, data+N);
}
in a utility header somewhere and then all that's required is:
const double values[] = { 2.0, 1.0, 42.0, -7 };
std::vector<double> array = makeVector(values);
But I can't wait for C++0x. I'm stuck because my code must also compile in Visual Studio. Boo.
I encountered this issue when installing a different package, and it could be caused by the GOROOT and GOPATH configuration on your PATH. I tend not to set GOROOT because my OS X installation handled it (I believe) for me.
Ensure the following in your .profile (or wherever you store profile configuration: .bash_profile, .zshrc, .bashrc, etc):
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin
Also, you likely want to unset GOROOT
, as well, in case that path is also incorrect.
Furthermore, be sure to clean your PATH, similarly to what I've done below, just before the GOPATH assignment, i.e.:
export PATH=$HOME/bin:/usr/local/bin:$PATH
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin
Then, source <.profile>
to activate
go get
Gradle 4.9+
gradle run --args='arg1 arg2'
This assumes your build.gradle
is configured with the Application plugin. Your build.gradle
should look similar to this:
plugins {
// Implicitly applies Java plugin
id: 'application'
}
application {
// URI of your main class/application's entry point (required)
mainClassName = 'org.gradle.sample.Main'
}
Pre-Gradle 4.9
Include the following in your build.gradle
:
run {
if (project.hasProperty("appArgs")) {
args Eval.me(appArgs)
}
}
Then to run: gradle run -PappArgs="['arg1', 'args2']"
Using merge
is different from lookup in Excel as it has potential to duplicate (multiply) your data if primary key constraint is not enforced in lookup table or reduce the number of records if you are not using all.x = T
.
To make sure you don't get into trouble with that and lookup safely, I suggest two strategies.
First one is to make a check on a number of duplicated rows in lookup key:
safeLookup <- function(data, lookup, by, select = setdiff(colnames(lookup), by)) {
# Merges data to lookup making sure that the number of rows does not change.
stopifnot(sum(duplicated(lookup[, by])) == 0)
res <- merge(data, lookup[, c(by, select)], by = by, all.x = T)
return (res)
}
This will force you to de-dupe lookup dataset before using it:
baseSafe <- safeLookup(largetable, house.ids, by = "HouseType")
# Error: sum(duplicated(lookup[, by])) == 0 is not TRUE
baseSafe<- safeLookup(largetable, unique(house.ids), by = "HouseType")
head(baseSafe)
# HouseType HouseTypeNo
# 1 Apartment 4
# 2 Apartment 4
# ...
Second option is to reproduce Excel behaviour by taking the first matching value from the lookup dataset:
firstLookup <- function(data, lookup, by, select = setdiff(colnames(lookup), by)) {
# Merges data to lookup using first row per unique combination in by.
unique.lookup <- lookup[!duplicated(lookup[, by]), ]
res <- merge(data, unique.lookup[, c(by, select)], by = by, all.x = T)
return (res)
}
baseFirst <- firstLookup(largetable, house.ids, by = "HouseType")
These functions are slightly different from lookup
as they add multiple columns.
Same thing happens when :port is in your local .env
again the double quotes does the trick
APP_URL="http://localhost:8000"
and then
php artisan config:clear
follow these steps:
open terminal go to your root dictionary by typing
cd /
you will see Library folder
Now follow this path Library/Java/JVM/bin
Once you get into bin
you can see the javac
file
Now you need to get the path of this folder for that just write this command
pwd
get the path for your javac
.
Generally, you cannot send a POST request using sendRedirect() method. You can use RequestDispatcher to forward() requests with parameters within the same web application, same context.
RequestDispatcher dispatcher = servletContext().getRequestDispatcher("test.jsp");
dispatcher.forward(request, response);
The HTTP spec states that all redirects must be in the form of a GET (or HEAD). You can consider encrypting your query string parameters if security is an issue. Another way is you can POST to the target by having a hidden form with method POST and submitting it with javascript when the page is loaded.
You can use like below -
this.setState(() => ({ subChartType1: value }), () => this.props.dispatch(setChartData(null)));
ExpressiveAnnotations gives you such a possibility:
[Required]
[AssertThat("Length(FieldA) + Length(FieldB) + Length(FieldC) + Length(FieldD) > 50")]
public string FieldA { get; set; }
This doesn't work because NaN
isn't equal to anything, including NaN
. Use pd.isnull(df.var2)
instead.
Here is an example:
I've an Order table with a DateTime field called OrderDate. I want to retrieve all orders where the order date is equals to 01/01/2006. there are next ways to do it:
1) WHERE DateDiff(dd, OrderDate, '01/01/2006') = 0
2) WHERE Convert(varchar(20), OrderDate, 101) = '01/01/2006'
3) WHERE Year(OrderDate) = 2006 AND Month(OrderDate) = 1 and Day(OrderDate)=1
4) WHERE OrderDate LIKE '01/01/2006%'
5) WHERE OrderDate >= '01/01/2006' AND OrderDate < '01/02/2006'

Let's suppose you want to find all int
not preceded by unsigned
:
With support for negative look-behind:
(?<!unsigned )int
Without support for negative look-behind:
((?!unsigned ).{9}|^.{0,8})int
Basically idea is to grab n preceding characters and exclude match with negative look-ahead, but also match the cases where there's no preceeding n characters. (where n is length of look-behind).
So the regex in question:
(?<!filename)\.js$
would translate to:
((?!filename).{8}|^.{0,7})\.js$
You might need to play with capturing groups to find exact spot of the string that interests you or you want't to replace specific part with something else.
I know this is quite an old post, but I would like to point out the following for people who will read it in the future: As per MS:
Do not use the IISReset.exe tool to restart the IIS services. Instead, use the NET STOP and NET START commands. For example, to stop and start the World Wide Web Publishing Service, run the following commands:
- NET STOP iisadmin /y
- NET START w3svc
There are two benefits to using the NET STOP/NET START commands to restart the IIS Services as opposed to using the IISReset.exe tool. First, it is possible for IIS configuration changes that are in the process of being saved when the IISReset.exe command is run to be lost. Second, using IISReset.exe can make it difficult to identify which dependent service or services failed to stop when this problem occurs. Using the NET STOP commands to stop each individual dependent service will allow you to identify which service fails to stop, so you can then troubleshoot its failure accordingly.
An HttpOnly
cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly
attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly
.
Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly
by just XSS and still have access to the cookie via JS and thus make the HttpOnly
on your cookie completely useless.
For one, you don't seem to be including jQuery itself in the header but only a bunch of plugins. As for the '<' error, it's impossible to tell without seeing the generated HTML.
you can try in this way if you are using thymeleaf
sec:authorize="hasAnyRole(T(com.orsbv.hcs.model.SystemRole).ADMIN.getName(),
T(com.orsbv.hcs.model.SystemRole).SUPER_USER.getName(),'ROLE_MANAGEMENT')"
this will return true if the user has the mentioned roles,false otherwise.
Please note you have to use sec tag in your html declaration tag like this
<html xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
A simple way to achieve what you want:
import cv2
s_img = cv2.imread("smaller_image.png")
l_img = cv2.imread("larger_image.jpg")
x_offset=y_offset=50
l_img[y_offset:y_offset+s_img.shape[0], x_offset:x_offset+s_img.shape[1]] = s_img
I suppose you want to take care of the alpha channel too. Here is a quick and dirty way of doing so:
s_img = cv2.imread("smaller_image.png", -1)
y1, y2 = y_offset, y_offset + s_img.shape[0]
x1, x2 = x_offset, x_offset + s_img.shape[1]
alpha_s = s_img[:, :, 3] / 255.0
alpha_l = 1.0 - alpha_s
for c in range(0, 3):
l_img[y1:y2, x1:x2, c] = (alpha_s * s_img[:, :, c] +
alpha_l * l_img[y1:y2, x1:x2, c])
Try to use:
mvn clean package install
This command should install your artifacts in you local maven repo.
PS: I see that this is an old question, but it may be helpful for somebody in the future.
Seaborn's barplot returns an axis-object (not a figure). This means you can do the following:
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
ax = sns.barplot(x = 'val', y = 'cat',
data = fake,
color = 'black')
ax.set(xlabel='common xlabel', ylabel='common ylabel')
plt.show()

If you want to set required to true
$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',true);
});
if you want to set required to false
$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',false);
});
The inclusion of your comparison class (or more specifically the AsEnumerable
call you needed to use to get it to work) meant that the sorting logic went from being based on the database server to being on the database client (your application). This meant that your client now needs to retrieve and then process a larger number of records, which will always be less efficient that performing the lookup on the database where the approprate indexes can be used.
You should try to develop a where clause that satisfies your requirements instead, see Using an IEqualityComparer with a LINQ to Entities Except clause for more details.

If this were for a plugin system, you would use MyClass as a base class and define all the required functions virtual. The plugin author would then derive from MyClass, override the virtuals and implement create_object

. Your main application would not need to be changed in any way.
String array[]=new String[]; and String array[]=new String[]{};
No difference,these are just different ways of declaring array
String array=new String[10]{}; got error why ?
This is because you can not declare the size of the array in this format.
right way is
String array[]=new String[]{"a","b"};

Beware of the restrictions. You have to respond quickly to this notification, you've got 5 seconds to complete the task. Take longer and Windows will kill your code unceremoniously. And your method is called asynchronously on a worker thread, the state of the program is entirely unpredictable so locking is likely to be required. Do make absolutely sure that an abort cannot cause trouble. For example, when saving state into a file, do make sure you save to a temporary file first and use File.Replace().

As of Android 3.0 (API Level 11) Android has a more recent and improved JSON Parser.
http://developer.android.com/reference/android/util/JsonReader.html
Reads a JSON (RFC 4627) encoded value as a stream of tokens. This stream includes both literal values (strings, numbers, booleans, and nulls) as well as the begin and end delimiters of objects and arrays. The tokens are traversed in depth-first order, the same order that they appear in the JSON document. Within JSON objects, name/value pairs are represented by a single token.

React Router v4
There's a couple of things that I needed to get this working smoothly.
The doc page on auth workflow has quite a lot of what is required.
However I had three issues
props.history
come from?Route
componentprops
?I ended up using:
<Route render>
which gets you props.history
which can then be passed down to the children.render={routeProps => <MyComponent {...props} {routeProps} />}
to combine other props
from this answer on 'react-router - pass props to handler component'N.B. With the render
method you have to pass through the props from the Route
component explicitly. You also want to use render
and not component
for performance reasons (component
forces a reload every time).
const App = (props) => (
<Route
path="/home"
render={routeProps => <MyComponent {...props} {...routeProps}>}
/>
)
const MyComponent = (props) => (
/**
* @link https://reacttraining.com/react-router/web/example/auth-workflow
* N.B. I use `props.history` instead of `history`
*/
<button onClick={() => {
fakeAuth.signout(() => props.history.push('/foo'))
}}>Sign out</button>
)
One of the confusing things I found is that in quite a few of the React Router v4 docs they use MyComponent = ({ match })
i.e. Object destructuring, which meant initially I didn't realise that Route
passes down three props, match
, location
and history
I think some of the other answers here are assuming that everything is done via JavaScript classes.
Here's an example, plus if you don't need to pass any props
through you can just use component
class App extends React.Component {
render () {
<Route
path="/home"
component={MyComponent}
/>
}
}
class MyComponent extends React.Component {
render () {
/**
* @link https://reacttraining.com/react-router/web/example/auth-workflow
* N.B. I use `props.history` instead of `history`
*/
<button onClick={() => {
this.fakeAuth.signout(() => this.props.history.push('/foo'))
}}>Sign out</button>
}
}

Well, I am a bit curious, so I just tested the three myself right after asking the question ;-)
Ok, this is not a very serious review, but here is what I can say:
I tried the tools with the default settings (it's important because you can pretty much choose your check rules) on the following script:

stdout.write('\n')
for x in xrange(-39, 39):

else:
stdout.write('*')
def mandelbrot(self, x, y):
cr = y - 0.5

zi = 0.0
zr = 0.0
for i in xrange(MAX_ITERATIONS) :
temp = zr * zi
zr2 = zr * zr
zi2 = zi * zi

zi = temp + temp + ci
if zi2 + zr2 > BAILOUT:
return i
return 0

Thanks to Rudiger Wolf, I discovered pep8
that does exactly what its name suggests: matching PEP8. It has found several syntax no-nos that Pylint did not. But Pylint found stuff that was not specifically linked to PEP8 but interesting. Both tools are interesting and complementary.
Eventually I will use both since there are really easy to install (via packages or setuptools) and the output text is so easy to chain.

You might read up on FILESTREAM. Here is some info from the docs that should help you decide:
If the following conditions are true, you should consider using FILESTREAM:
- Objects that are being stored are, on average, larger than 1 MB.
- Fast read access is important.
- You are developing applications that use a middle tier for application logic.
For smaller objects, storing varbinary(max) BLOBs in the database often provides better streaming performance.
Something like this?
public static T ConvertValue<T>(string value)
{
return (T)Convert.ChangeType(value, typeof(T));
}
You can then use it like this:
int val = ConvertValue<int>("42");
Edit:
You can even do this more generic and not rely on a string
parameter provided the type U
implements IConvertible
- this means you have to specify two type parameters though:
public static T ConvertValue<T,U>(U value) where U : IConvertible
{
return (T)Convert.ChangeType(value, typeof(T));
}
I considered catching the InvalidCastException
exception that might be raised by Convert.ChangeType()
- but what would you return in this case? default(T)
? It seems more appropriate having the caller deal with the exception.

Check for multiple versions of the same jar file on your classpath.

An important point that often bites new Python programmers but the other posters haven't made explicit is that strings in Python are immutable -- you can't ever modify them in place.
You need to retrain yourself when working with strings in Python so that instead of thinking, "How can I modify this string?" instead you're thinking "how can I create a new string that has some pieces from this one I've already gotten?"
I was facing a similar problem. The solution that I found out was :
Declare an interface in your DialogFragment just like James McCracken has explained above.
Implement the interface in your activity (not fragment! That is not a good practice).
From the callback method in your activity, call a required public function in your fragment which does the job that you want to do.
Thus, it becomes a two-step process : DialogFragment -> Activity and then Activity -> Fragment
You can use a generic collection, like List<>
List<string> list = new List<string>();
// add
list.Add("element");
// remove
list.Remove("element");
Some things wrong with the example:
fprintf(stderr, ....
fgetc()
rather than getc()
. getc()
is a macro, fgetc()
is a proper functiongetc()
returns an int
so ch
should be declared as an int
. This is important since the comparison with EOF
will be handled correctly. Some 8 bit character sets use 0xFF
as a valid character (ISO-LATIN-1 would be an example) and EOF
which is -1, will be 0xFF
if assigned to a char
.There is a potential buffer overflow at the line
lineBuffer[count] = '\0';
If the line is exactly 128 characters long, count
is 128 at the point that gets executed.
As others have pointed out, line
is a locally declared array. You can't return a pointer to it.
strncpy(count + 1)
will copy at most count + 1
characters but will terminate if it hits '\0'
Because you set lineBuffer[count]
to '\0'
you know it will never get to count + 1
. However, if it did, it would not put a terminating '\0'
on, so you need to do it. You often see something like the following:
char buffer [BUFFER_SIZE];
strncpy(buffer, sourceString, BUFFER_SIZE - 1);
buffer[BUFFER_SIZE - 1] = '\0';
if you malloc()
a line to return (in place of your local char
array), your return type should be char*
- drop the const
.

Script will then show log of all pods that start with that "deployment-name".
I've had the same problem.
Use CSS to hide is not the best solution, because sometimes you want users without JS can see the div.. The cleanest solution is to hide the div with JQuery. But the div is visible about 0.5 seconde, which is problematic if the div is on the top of the page.
In these cases, I use an intermediate solution, without JQuery. This one works and is immediate :
<script>document.write('<style>.js_hidden { display: none; }</style>');</script>
<div class="js_hidden">This div will be hidden for JS users, and visible for non JS users.</div>
Of course, you can still add all the effects you want on the div, JQuery toggle() for example. And you will get the best behaviour possible (imho) :
There is no event raised when a class changes. The alternative is to manually raise an event when you programatically change the class:
$someElement.on('event', function() {
$('#myDiv').addClass('submission-ok').trigger('classChange');
});
// in another js file, far, far away
$('#myDiv').on('classChange', function() {
// do stuff
});
UPDATE
This question seems to be gathering some visitors, so here is an update with an approach which can be used without having to modify existing code using the new MutationObserver
:
var $div = $("#foo");_x000D_
var observer = new MutationObserver(function(mutations) {_x000D_
mutations.forEach(function(mutation) {_x000D_
if (mutation.attributeName === "class") {_x000D_
var attributeValue = $(mutation.target).prop(mutation.attributeName);_x000D_
console.log("Class attribute changed to:", attributeValue);_x000D_
}_x000D_
});_x000D_
});_x000D_
observer.observe($div[0], {_x000D_
attributes: true_x000D_
});_x000D_
_x000D_
$div.addClass('red');
_x000D_
.red { color: #C00; }
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="foo" class="bar">#foo.bar</div>
_x000D_
Be aware that the MutationObserver
is only available for newer browsers, specifically Chrome 26, FF 14, IE 11, Opera 15 and Safari 6. See MDN for more details. If you need to support legacy browsers then you will need to use the method I outlined in my first example.
I suggest you using bootstrap which works perfectly:
@import url('http://getbootstrap.com/dist/css/bootstrap.css');_x000D_
html, body, .container-table {_x000D_
height: 100%;_x000D_
}_x000D_
.container-table {_x000D_
display: table;_x000D_
}_x000D_
.vertical-center-row {_x000D_
display: table-cell;_x000D_
vertical-align: middle;_x000D_
}

You need to include a jar that this class exists in. You can find it here
If using Maven, you can add the following dependency declaration:
<dependency>
<groupId>com.google.code.findbugs</groupId>
<artifactId>jsr305</artifactId>
<version>3.0.2</version>
</dependency>
and for Gradle:
dependencies {
testImplementation 'com.google.code.findbugs:jsr305:3.0.2'
}
Swift:
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
...
// remove separator for last cell
cell.separatorInset = indexPath.row < numberOfRowsInSection-1
? tableView.separatorInset
: UIEdgeInsets(top: 0, left: tableView.bounds.size.width, bottom: 0, right: 0)
return cell
}
Objective-C:
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
...
// remove separator for last cell
cell.separatorInset = (indexPath.row < numberOfRowsInSection-1)
? tableView.separatorInset
: UIEdgeInsetsMake(0.f, tableView.bounds.size.width, 0.f, 0.f);
return cell;
}
To be sure that you could clone the repo, go to any temporary directory and clone the project there:
git clone ssh://[email protected]/home/user/private/repos/project_hub.git
This will clone your stuff into a project_hub
directory.
Once the cloning has finished, you could move this directory wherever you want:
mv project_hub /path/to/new/location
This is safe and doesn't require any magical stuff around.
A trick I learned from this PR if you don't want to define it as a static final variable but want to save a bit of overhead and guarantee thread safe.
private static final ThreadLocal<ObjectMapper> om = new ThreadLocal<ObjectMapper>() {
@Override
protected ObjectMapper initialValue() {
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
return objectMapper;
}
};
public static ObjectMapper getObjectMapper() {
return om.get();
}

You may look into something kind of Unique List as follows
public class UniqueList<T>
{
public List<T> List
{
get;
private set;
}
List<T> _internalList;
public static UniqueList<T> NewList
{
get
{
return new UniqueList<T>();
}
}
private UniqueList()
{
_internalList = new List<T>();
List = new List<T>();
}
public void Add(T value)
{
List.Clear();
_internalList.Add(value);
List.AddRange(_internalList.Distinct());
//return List;
}
public void Add(params T[] values)
{
List.Clear();
_internalList.AddRange(values);
List.AddRange(_internalList.Distinct());
// return List;
}
public bool Has(T value)
{
return List.Contains(value);
}
}
and you can use it like follows
var uniquelist = UniqueList<string>.NewList;
uniquelist.Add("abc","def","ghi","jkl","mno");
uniquelist.Add("abc","jkl");
var _myList = uniquelist.List;
will only return "abc","def","ghi","jkl","mno"
always even when duplicates are added to it
Could you use jQuery, since it's cross-browser compatible?
function isOnScreen(element)
{
var curPos = element.offset();
var curTop = curPos.top;
var screenHeight = $(window).height();
return (curTop > screenHeight) ? false : true;
}
And then call the function using something like:
if(isOnScreen($('#myDivId'))) { /* Code here... */ };
I recently created a small extension to Jupyter named jupyter-navbar. It searches for headers written in markdown cells, and displays links to them in the sidebar in a hierarchical fashion. The sidebar is resizable and collapsible. See screenshot below.
It is easy to install, and takes advantage of the 'custom' JS and CSS codes that get executed whenever a notebook is opened, so you don't need to manually run it.
I guess you want user to be redirected to ~/AreaZ
URL once (s)he has visited ~/
URL.
I'd achieve by means of the following code within your root HomeController
.
public class HomeController
{
public ActionResult Index()
{
return RedirectToAction("ActionY", "ControllerX", new { Area = "AreaZ" });
}
}
And the following route in Global.asax
.
routes.MapRoute(
"Redirection to AreaZ",
String.Empty,
new { controller = "Home ", action = "Index" }
);
I'd recommend you to use my Project Netroid, It's based on Volley. I have added some features to it such as multi-events callback, file download management. This could be of some help.

A submodule is its own repo/work-area, with its own .git
directory.
So, first commit/push
your submodule's changes:
$ cd path/to/submodule
$ git add <stuff>
$ git commit -m "comment"
$ git push
Then, update your main project to track the updated version of the submodule:
$ cd /main/project
$ git add path/to/submodule
$ git commit -m "updated my submodule"
$ git push
Here's what I had to do to setup basic auth on Ubuntu 14.04 (didn't find a guide anywhere else)
/etc/squid3/squid.conf
instead of the super bloated default config file
auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
# Choose the port you want. Below we set it to default 3128.
http_port 3128
Please note the basic_ncsa_auth program instead of the old ncsa_auth
For squid 2.x you need to edit /etc/squid/squid.conf
file and place:
auth_param basic program /usr/lib/squid/digest_pw_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
sudo htpasswd -c /etc/squid3/passwords username_you_like
and enter a password twice for the chosen username then
sudo service squid3 restart
sudo htpasswd -c /etc/squid/passwords username_you_like
and enter a password twice for the chosen username then
sudo service squid restart
For the many people that asked me: the 2 tools produce different file formats:
htdigest
stores the password in plain text.htpasswd
stores the password hashed (various hashing algos are available)Despite this difference in format basic_ncsa_auth
will still be able to parse a password file generated with htdigest
. Hence you can alternatively use:
sudo htdigest -c /etc/squid3/passwords realm_you_like username_you_like
Beware that this approach is empirical, undocumented and may not be supported by future versions of Squid.
On Ubuntu 14.04 htdigest
and htpasswd
are both available in the [apache2-utils][1]
package.
Similar as above applies, but file paths are different.
Install squid
brew install squid
Start squid service
brew services start squid
Squid config file is stored at /usr/local/etc/squid.conf
.
Comment or remove following line:
http_access allow localnet
Then similar to linux config (but with updated paths) add this:
auth_param basic program /usr/local/Cellar/squid/4.8/libexec/basic_ncsa_auth /usr/local/etc/squid_passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
Note that path to basic_ncsa_auth
may be different since it depends on installed version when using brew
, you can verify this with ls /usr/local/Cellar/squid/
. Also note that you should add the above just bellow the following section:
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
Now generate yourself a user:password basic auth credential (note: htpasswd
and htdigest
are also both available on MacOS)
htpasswd -c /usr/local/etc/squid_passwords username_you_like
Restart the squid service
brew services restart squid

Try this function out to calculate distance between to points of latitude and longitude
function calculateDistanceBetweenTwoPoints($latitudeOne='', $longitudeOne='', $latitudeTwo='', $longitudeTwo='',$distanceUnit ='',$round=false,$decimalPoints='')
{
if (empty($decimalPoints))
{
$decimalPoints = '3';
}
if (empty($distanceUnit)) {
$distanceUnit = 'KM';
}
$distanceUnit = strtolower($distanceUnit);
$pointDifference = $longitudeOne - $longitudeTwo;
$toSin = (sin(deg2rad($latitudeOne)) * sin(deg2rad($latitudeTwo))) + (cos(deg2rad($latitudeOne)) * cos(deg2rad($latitudeTwo)) * cos(deg2rad($pointDifference)));
$toAcos = acos($toSin);
$toRad2Deg = rad2deg($toAcos);
$toMiles = $toRad2Deg * 60 * 1.1515;
$toKilometers = $toMiles * 1.609344;
$toNauticalMiles = $toMiles * 0.8684;
$toMeters = $toKilometers * 1000;
$toFeets = $toMiles * 5280;
$toYards = $toFeets / 3;
switch (strtoupper($distanceUnit))
{
case 'ML'://miles
$toMiles = ($round == true ? round($toMiles) : round($toMiles, $decimalPoints));
return $toMiles;
break;
case 'KM'://Kilometers
$toKilometers = ($round == true ? round($toKilometers) : round($toKilometers, $decimalPoints));
return $toKilometers;
break;
case 'MT'://Meters
$toMeters = ($round == true ? round($toMeters) : round($toMeters, $decimalPoints));
return $toMeters;
break;
case 'FT'://feets
$toFeets = ($round == true ? round($toFeets) : round($toFeets, $decimalPoints));
return $toFeets;
break;
case 'YD'://yards
$toYards = ($round == true ? round($toYards) : round($toYards, $decimalPoints));
return $toYards;
break;
case 'NM'://Nautical miles
$toNauticalMiles = ($round == true ? round($toNauticalMiles) : round($toNauticalMiles, $decimalPoints));
return $toNauticalMiles;
break;
}
}
Then use the fucntion as
echo calculateDistanceBetweenTwoPoints('11.657740','77.766270','11.074820','77.002160','ML',true,5);

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.
Ports 57311 and 57312 are randomly assigned ports used for RMI communication. These ports change each time Cassandra starts up, but need to be open in the firewall, along with 8080/7199 (depending on version), to allow for remote JMX access. Something that doesn't appear to be particularly well documented, but has tripped me up in the past.
You want to assign something like this to onfocus:
if (this.value == this.defaultValue)
this.value = ''
this.className = ''
and this to onblur:
if (this.value == '')
this.value = this.defaultValue
this.className = 'placeholder'
(You can use something a bit cleverer, like a framework function, to do the classname switching if you want.)
With some CSS like this:
input.placeholder{
color: gray;
font-style: italic;
}
You can use the -TotalCount
parameter of the Get-Content
cmdlet to read the first n
lines, then use Select-Object
to return only the n
th line:
Get-Content file.txt -TotalCount 9 | Select-Object -Last 1;
Per the comment from @C.B. this should improve performance by only reading up to and including the n
th line, rather than the entire file. Note that you can use the aliases -First
or -Head
in place of -TotalCount
.
Mongoose and multiple database in single node.js project
use useDb to solve this issue
example
//product databse
const myDB = mongoose.connection.useDb('product');
module.exports = myDB.model("Snack", snackSchema);
//user databse
const myDB = mongoose.connection.useDb('user');
module.exports = myDB.model("User", userSchema);
What could be easier than something like this:
import tempfile
for i in range(400):
with tempfile.TemporaryFile() as tf:
for j in range(1000):
tf.write('Line {} of file {}'.format(j,i))
That creates 400 temp files and writes 1000 lines to each temp file. It executes in less than 1/2 second on my unremarkable machine. Each temp file of the total is created and deleted as the context manager opens and closes in this case. It is fast, secure, and cross platform.
Using tempfile is a lot better than trying to reinvent it.
Use awk
with a flag to trigger the print when necessary:
$ awk '/abc/{flag=1;next}/mno/{flag=0}flag' file
def1
ghi1
jkl1
def2
ghi2
jkl2
How does this work?
/abc/
matches lines having this text, as well as /mno/
does. /abc/{flag=1;next}
sets the flag
when the text abc
is found. Then, it skips the line. /mno/{flag=0}
unsets the flag
when the text mno
is found.flag
is a pattern with the default action, which is to print $0
: if flag
is equal 1 the line is printed.For a more detailed description and examples, together with cases when the patterns are either shown or not, see How to select lines between two patterns?.
WE had this issue. everything was setup fine in terms of permissions and security.
after MUCH needling around in the haystack. the issue was some sort of heuristics. in the email body , anytime a certain email address was listed, we would get the above error message from our exchange server.
it took 2 days of crazy testing and hair pulling to find this.
so if you have checked everything out, try changing the email body to only the word 'test'. If after that, your email goes out fine, you are having some sort of spam/heuristic filter issue like we were
I suggest you to have a ~/.mongorc.js
file so you do not have to set the default size everytime.
# execute in your terminal
touch ~/.mongorc.js
echo 'DBQuery.shellBatchSize = 100;' > ~/.mongorc.js
# add one more line to always prettyprint the ouput
echo 'DBQuery.prototype._prettyShell = true; ' >> ~/.mongorc.js
To know more about what else you can do, I suggest you to look at this article: http://mo.github.io/2017/01/22/mongo-db-tips-and-tricks.html

CPU Bound means the rate at which process progresses is limited by the speed of the CPU. A task that performs calculations on a small set of numbers, for example multiplying small matrices, is likely to be CPU bound.
I/O Bound means the rate at which a process progresses is limited by the speed of the I/O subsystem. A task that processes data from disk, for example, counting the number of lines in a file is likely to be I/O bound.
Memory bound means the rate at which a process progresses is limited by the amount memory available and the speed of that memory access. A task that processes large amounts of in memory data, for example multiplying large matrices, is likely to be Memory Bound.
Cache bound means the rate at which a process progress is limited by the amount and speed of the cache available. A task that simply processes more data than fits in the cache will be cache bound.
I/O Bound would be slower than Memory Bound would be slower than Cache Bound would be slower than CPU Bound.
The solution to being I/O bound isn't necessarily to get more Memory. In some situations, the access algorithm could be designed around the I/O, Memory or Cache limitations. See Cache Oblivious Algorithms.
Step 1: Simply put all the required code in a "MAIN.BAT" file.
Step 2: Create another bat file, say MainCaller.bat, and just copy/paste these 3 lines of code:
REM THE MAIN FILE WILL BE CALLED FROM HERE..........
CD "File_Path_Where_Main.bat_is_located"
MAIN.BAT > log.txt
Step 3: Just double click "MainCaller.bat".
All the output will be logged into the text file named "log".
Short answer: in the Vault. Since Windows 7, a Vault was created for storing any sensitive data among it the credentials of Internet Explorer. The Vault is in fact a LocalSystem service - vaultsvc.dll.
Long answer: Internet Explorer allows two methods of credentials storage: web sites credentials (for example: your Facebook user and password) and autocomplete data. Since version 10, instead of using the Registry a new term was introduced: Windows Vault. Windows Vault is the default storage vault for the credential manager information.
You need to check which OS is running. If its Windows 8 or greater, you call VaultGetItemW8. If its isn't, you call VaultGetItemW7.
To use the "Vault", you load a DLL named "vaultcli.dll" and access its functions as needed.
A typical C++ code will be:
hVaultLib = LoadLibrary(L"vaultcli.dll");
if (hVaultLib != NULL)
{
pVaultEnumerateItems = (VaultEnumerateItems)GetProcAddress(hVaultLib, "VaultEnumerateItems");
pVaultEnumerateVaults = (VaultEnumerateVaults)GetProcAddress(hVaultLib, "VaultEnumerateVaults");
pVaultFree = (VaultFree)GetProcAddress(hVaultLib, "VaultFree");
pVaultGetItemW7 = (VaultGetItemW7)GetProcAddress(hVaultLib, "VaultGetItem");
pVaultGetItemW8 = (VaultGetItemW8)GetProcAddress(hVaultLib, "VaultGetItem");
pVaultOpenVault = (VaultOpenVault)GetProcAddress(hVaultLib, "VaultOpenVault");
pVaultCloseVault = (VaultCloseVault)GetProcAddress(hVaultLib, "VaultCloseVault");
bStatus = (pVaultEnumerateVaults != NULL)
&& (pVaultFree != NULL)
&& (pVaultGetItemW7 != NULL)
&& (pVaultGetItemW8 != NULL)
&& (pVaultOpenVault != NULL)
&& (pVaultCloseVault != NULL)
&& (pVaultEnumerateItems != NULL);
}
Then you enumerate all stored credentials by calling
VaultEnumerateVaults
Then you go over the results.
The code below will work just fine in all browsers:

I just want to propose another alternative that will concern some of you :
android:configChanges="orientation|keyboardHidden"
implies that we explicitly declare the layout to be injected.
In case we want to keep the automatic injection thanks to the layout-land and layout folders. All you have to do is add it to the onCreate:
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
getSupportActionBar().hide();
} else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
getSupportActionBar().show();
}
Here, we display or not the actionbar depending on the orientation of the phone
You're going to need DATEPART here. You can concatenate the results of the DATEPART calls together.
To get the month abbreviations, you might be able to use DATENAME; if that doesn't work for you, you can use a CASE statement on the DATEPART.
DATEPART also works for the time field.
I can think of a couple of ways of getting the AM/PM indicator, including comparing new dates built via DATEPART or calculating the total seconds elapsed in the day and comparing that to known AM/PM thresholds.
As basZero mentioned, X-Forwarded-For should be checked for comma. (Look at : http://en.wikipedia.org/wiki/X-Forwarded-For). The general format of the field is: X-Forwarded-For: clientIP, proxy1, proxy2... and so on. So we will be seeing something like this : X-FORWARDED-FOR: 129.77.168.62, 129.77.63.62.
One should NEVER call System.exit(0)
for these reasons:
Quitting the program "normally" provides the same exit code to the operating system as System.exit(0)
so it is redundant.
If your program cannot quit "normally" you have lost control of your development [design]. You should have always full control of the system state.
By the way: Returning other return codes than 0 does make sense if you want to indicate abnormal program termination.
Java has a LinkedList implementation, that you might wanna check out. You can download the JDK and it's sources at java.sun.com.

You could initialize discount to 0 as long as your code is guaranteed not to try and use it before it is initialized. That would remove one check I suppose, I can't think of anything else.

After trying some of the answers in this post, I consulted with Louie Mantia (former Apple, Square, and Iconfactory designer) and all the answers so far on this post are wrong (or at least incomplete). Apple starts with the 57px icon and a radius of 10 then scales up or down from there. Thus you can calculate the radius for any icon size using 10/57 x new size
(for example 10/57 x 114
gives 20, which is the proper radius for a 114px icon). Here is a list of the most commonly used icons, proper naming conventions, pixel dimensions, and corner radii.
Also, as mentioned in other answers, you don't actually want to crop any of the images you use in the binary or submit to Apple. Those should all be square and not have any transparency. Apple will automatically mask each icon in the appropriate context.
Knowing the above is important, however, for icon usage within app UI where you have to apply the mask in code, or pre-rendered in photoshop. It's also helpful when creating artwork for websites and other promotional material.
Additional reading:
Neven Mrgan on additional icon sizes and other design considerations: ios app icon sizes
Bjango's Marc Edwards on the different options for creating roundrects in Photoshop and why it matters: roundrect
Apple's official docs on icon size and design considerations: Icons and Images
Update:
I did some tests in Photoshop CS6 and it seems as though 3 digits after the decimal point is enough precision to end up with the exact same vector (at least as displayed by Photoshop at 3200% zoom). The Round Rect Tool sometimes rounds the input to the nearest whole number, but you can see a significant difference between 90 and 89.825. And several times the Round Rectangle Tool didn't round up and actually showed multiple digits after the decimal point. Not sure what's going on there, but it's definitely using and storing the more precise number that was entered.
Anyhow, I've updated the list above to include just 3 digits after the decimal point (before there were 13!). In most situations it would probably be hard to tell the difference between a transparent 512px icon masked at a 90px radius and one masked at 89.825, but the antialiasing of the rounded corner would definitely end up slightly different and would likely be visible in certain circumstances especially if a second, more precise mask is applied by Apple, in code, or otherwise.
Another option is git merge --squash <feature branch>
then finally do a git commit
.
From Git merge
--squash
--no-squash
Produce the working tree and index state as if a real merge happened (except for the merge information), but do not actually make a commit or move the
HEAD
, nor record$GIT_DIR/MERGE_HEAD
to cause the nextgit commit
command to create a merge commit. This allows you to create a single commit on top of the current branch whose effect is the same as merging another branch (or more in case of an octopus).
Just to add that there is also java.text.MessageFormat with the benefit of having numeric argument indexes.
Appending the 1st example from the documentation
int planet = 7;
String event = "a disturbance in the Force";
String result = MessageFormat.format(
"At {1,time} on {1,date}, there was {2} on planet {0,number,integer}.",
planet, new Date(), event);
Result:
At 12:30 PM on Jul 3, 2053, there was a disturbance in the Force on planet 7.
You may try with below query :
INSERT INTO errortable (dateupdated,table1id)
VALUES (to_date(to_char(sysdate,'dd/mon/yyyy hh24:mi:ss'), 'dd/mm/yyyy hh24:mi:ss' ),1083 );
To view the result of it:
SELECT to_char(hire_dateupdated, 'dd/mm/yyyy hh24:mi:ss')
FROM errortable
WHERE table1id = 1083;
If you guys are facing "Permission Denial: starting Intent..." error or if the app is getting crash without any reason during launching the app - Then use this single line code in Manifest
android:exported="true"
Please be careful with finish(); , if you missed out it the app getting frozen. if its mentioned the app would be a smooth launcher.
finish();
The other solution only works for two activities that are in the same application. In my case, application B doesn't know class com.example.MyExampleActivity.class
in the code, so compile will fail.
I searched on the web and found something like this below, and it works well.
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.example", "com.example.MyExampleActivity"));
startActivity(intent);
You can also use the setClassName method:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.hotfoot.rapid.adani.wheeler.android", "com.hotfoot.rapid.adani.wheeler.android.view.activities.MainActivity");
startActivity(intent);
finish();
You can also pass the values from one app to another app :
Intent launchIntent = getApplicationContext().getPackageManager().getLaunchIntentForPackage("com.hotfoot.rapid.adani.wheeler.android.LoginActivity");
if (launchIntent != null) {
launchIntent.putExtra("AppID", "MY-CHILD-APP1");
launchIntent.putExtra("UserID", "MY-APP");
launchIntent.putExtra("Password", "MY-PASSWORD");
startActivity(launchIntent);
finish();
} else {
Toast.makeText(getApplicationContext(), " launch Intent not available", Toast.LENGTH_SHORT).show();
}
You could just split the frontend and backend. The frontend is hosted on the customers server with an API that makes calls to the backend on your server. This keeps all of the proprietary code proprietary and forces users to sign up / pay for subscriptions.
Encountered similar issue, my server is behind nginx. There's no error in web server's (Python flask) log, but some error messsage in nginx log.
[crit] 31054#31054: *269464 open() "/var/cache/nginx/proxy_temp/3/45/0000000453" failed (13: Permission denied) while reading upstream
I fixed this issue by correcting the permission of directory:
/var/cache/nginx
My answer is not exactly what is asked in the question. Rather I am giving a solution exactly how easily we can read a file into out java application from our project class path.
For example suppose a config file name example.xml is located in a path like below:-
com.myproject.config.dev
and our java executable class file is in the below path:-
com.myproject.server.main
now just check in both the above path which is the nearest common directory/folder from where you can access both dev and main directory/folder (com.myproject.server.main - where our application’s java executable class is existed) – We can see that it is myproject folder/directory which is the nearest common directory/folder from where we can access our example.xml file. Therefore from a java executable class resides in folder/directory main we have to go back two steps like ../../ to access myproject. Now following this, see how we can read the file:-
package com.myproject.server.main;
class Example {
File xmlFile;
public Example(){
String filePath = this.getClass().getResource("../../config/dev/example.xml").getPath();
this.xmlFile = new File(filePath);
}
public File getXMLFile() {
return this.xmlFile;
}
public static void main(String args[]){
Example ex = new Example();
File xmlFile = ex.getXMLFile();
}
}
#include <stdio.h>
// read a line into str, return length
int read_line(char str[]) {
int c, i=0;
c = getchar();
while (c != '\n' && c != EOF) {
str[i] = c;
c = getchar();
i++;
}
str[i] = '\0';
return i;
}
From the proxy_pass documentation:
A special case is using variables in the proxy_pass statement: The requested URL is not used and you are fully responsible to construct the target URL yourself.
Since you're using $1 in the target, nginx relies on you to tell it exactly what to pass. You can fix this in two ways. First, stripping the beginning of the uri with a proxy_pass is trivial:
location /service/ {
# Note the trailing slash on the proxy_pass.
# It tells nginx to replace /service/ with / when passing the request.
proxy_pass http://apache/;
}
Or if you want to use the regex location, just include the args:
location ~* ^/service/(.*) {
proxy_pass http://apache/$1$is_args$args;
}
How to filter (skip) non-UTF8 charachers from array?
To address this comment in @uname01's post and the OP, ignore the errors:
Code
>>> b'\x80abc'.decode("utf-8", errors="ignore")
'abc'
Details
From the docs, here are more examples using the same errors
parameter:
>>> b'\x80abc'.decode("utf-8", "replace")
'\ufffdabc'
>>> b'\x80abc'.decode("utf-8", "backslashreplace")
'\\x80abc'
>>> b'\x80abc'.decode("utf-8", "strict")
Traceback (most recent call last):
...
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0:
invalid start byte
The errors argument specifies the response when the input string can’t be converted according to the encoding’s rules. Legal values for this argument are
'strict'
(raise aUnicodeDecodeError
exception),'replace'
(useU+FFFD
,REPLACEMENT CHARACTER
), or'ignore'
(just leave the character out of the Unicode result).
Rails 4 has been updated, so the change method can be used in the migration to drop a column and the migration will successfully rollback. Please read the following warning for Rails 3 applications:
Rails 3 Warning
Please note that when you use this command:
rails generate migration RemoveFieldNameFromTableName field_name:datatype
The generated migration will look something like this:
def up
remove_column :table_name, :field_name
end
def down
add_column :table_name, :field_name, :datatype
end
Make sure to not use the change method when removing columns from a database table (example of what you don't want in the migration file in Rails 3 apps):
def change
remove_column :table_name, :field_name
end
The change method in Rails 3 is not smart when it comes to remove_column, so you will not be able to rollback this migration.
You're comparing the message with the empty string using ==
.
First, your comparison is wrong because the message will be null (and not the empty string).
Second, it's wrong because Objects must be compared with equals()
and not with ==
.
Third, it's wrong because you should avoid scriptlets in JSP, and use the JSP EL, the JSTL, and other custom tags instead:
<c:id test="${!empty message}">
<c:out value="${message}"/>
</c:if>
select to_char(sysdate, 'Month') from dual
in your example will be:
select to_char(to_date('15-11-2010', 'DD-MM-YYYY'), 'Month') from dual
As of now, Installing the apks to the /system
directory seems to be working using adb push
command.
Some hidden service was automatically remounting the /system
directory in read-only
mode.
Any way I was able to install the Play store in a normal virtual-machine ( Ie, non-Google-Api virtual machine ) by simply mounting the system.img
file from my OS and by copying over the files.
# To be executed as root user in your Unix based OS
mkdir sys_temp
mount $SDK_HOME/system-images/android-23/default/x86/system.img sys_temp -o loop
cp Phonesky.apk GmsCore.apk GoogleLoginService.apk GoogleServicesFramework.apk ./sys_temp/priv-app/
umount sys_temp
rmdir sys_temp
The APK files can be pulled from any real Android device running Google Apps by using adb pull
command
[ To get the exact path of the apks, we can use command
pm list packages -f
inside the adb shell ]
This is old, but someone else may stumble on it as I did. When you connect to the DataCast, you are talking to a daemon that can access the database. It was intended that a customer would write some code to access the database and store the results somewhere. It just happens that telnet works to access data manually. netcat should also work. ssh obviously will not.
Here is a code to draw a fill elipse, you can use the same method but replacing de xcenter and y center with radius
void drawFilledelipse(GLfloat x, GLfloat y, GLfloat xcenter,GLfloat ycenter) {
int i;
int triangleAmount = 20; //# of triangles used to draw circle
//GLfloat radius = 0.8f; //radius
GLfloat twicePi = 2.0f * PI;
glBegin(GL_TRIANGLE_FAN);
glVertex2f(x, y); // center of circle
for (i = 0; i <= triangleAmount; i++) {
glVertex2f(
x + ((xcenter+1)* cos(i * twicePi / triangleAmount)),
y + ((ycenter-1)* sin(i * twicePi / triangleAmount))
);
}
glEnd();
}
Collection is the main interface of Java Collections hierarchy and List(Sequence) is one of the sub interfaces that defines an ordered collection.
I think that this construct: if exists (select...
is specific for MS SQL. In MySQL EXISTS
predicate tells you whether the subquery finds any rows and it's used like this: SELECT column1 FROM t1 WHERE EXISTS (SELECT * FROM t2);
You can rewrite the above lines of code like this:
DELIMITER $$
CREATE PROCEDURE `checando`(in nombrecillo varchar(30), in contrilla varchar(30), out resultado int)
BEGIN
DECLARE count_prim INT;
DECLARE count_sec INT;
SELECT COUNT(*) INTO count_prim FROM compas WHERE nombre = nombrecillo AND contrasenia = contrilla;
SELECT COUNT(*) INTO count_sec FROM FROM compas WHERE nombre = nombrecillo;
if (count_prim > 0) then
set resultado = 0;
elseif (count_sec > 0) then
set resultado = -1;
else
set resultado = -2;
end if;
SELECT resultado;
END
If you don't want to have your .gitignore interfere with anyone else's repository, you can also use .git/info/exclude

An official answer would be from
You can also see from this lovely diagram why the branch predictor gets confused.
Each element in the original code is a random value
data[c] = std::rand() % 256;
so the predictor will change sides as the std::rand()
blow.
On the other hand, once it's sorted, the predictor will first move into a state of strongly not taken and when the values change to the high value the predictor will in three runs through change all the way from strongly not taken to strongly taken.
Look at the types of those properties:
In [1]: import datetime
In [2]: d = datetime.date.today()
In [3]: type(d.month)
Out[3]: <type 'int'>
In [4]: type(d.day)
Out[4]: <type 'int'>
Both are integers. So there is no automatic way to do what you want. So in the narrow sense, the answer to your question is no.
If you want leading zeroes, you'll have to format them one way or another. For that you have several options:
In [5]: '{:02d}'.format(d.month)
Out[5]: '03'
In [6]: '%02d' % d.month
Out[6]: '03'
In [7]: d.strftime('%m')
Out[7]: '03'
In [8]: f'{d.month:02d}'
Out[8]: '03'
Use a JSON library to parse the string and retrieve the value.
The following very basic example uses the built-in JSON parser from Android.
String jsonString = "{ \"name\" : \"John\", \"age\" : \"20\", \"address\" : \"some address\" }";
JSONObject jsonObject = new JSONObject(jsonString);
int age = jsonObject.getInt("age");
More advanced JSON libraries, such as jackson, google-gson, json-io or genson, allow you to convert JSON objects to Java objects directly.
I never liked the way of asserting exceptions with Junit. If I use the "expected" in the annotation, seems from my point of view we're violating the "given, when, then" pattern because the "then" is placed at the top of the test definition.
Also, if we use "@Rule", we have to deal with so much boilerplate code. So, if you can install new libraries for your tests, I'd suggest to have a look to the AssertJ (that library now comes with SpringBoot)
Then a test which is not violating the "given/when/then" principles, and it is done using AssertJ to verify:
1 - The exception is what we're expecting. 2 - It has also an expected message
Will look like this:
@Test
void should_throwIllegalUse_when_idNotGiven() {
//when
final Throwable raisedException = catchThrowable(() -> getUserDAO.byId(null));
//then
assertThat(raisedException).isInstanceOf(IllegalArgumentException.class)
.hasMessageContaining("Id to fetch is mandatory");
}
In order to give a value in the table, we need to give a command:
php artisan make:migration create_users_table
and after then this command line
php artisan migrate
......
Haven't seen any fully-native solutions, so here's one:
return str == null || str.chars().allMatch(Character::isWhitespace);
Basically, use the native Character.isWhitespace() function. From there, you can achieve different levels of optimization, depending on how much it matters (I can assure you that in 99.99999% of use cases, no further optimization is necessary):
return str == null || str.length() == 0 || str.chars().allMatch(Character::isWhitespace);
Or, to be really optimal (but hecka ugly):
int len;
if (str == null || (len = str.length()) == 0) return true;
for (int i = 0; i < len; i++) {
if (!Character.isWhitespace(str.charAt(i))) return false;
}
return true;
One thing I like to do:
Optional<String> notBlank(String s) {
return s == null || s.chars().allMatch(Character::isWhitepace))
? Optional.empty()
: Optional.of(s);
}
...
notBlank(myStr).orElse("some default")
This worked for me:
@Column(name = "transactionCreatedDate", nullable = false, updatable = false, insertable = false, columnDefinition = "TIMESTAMP DEFAULT CURRENT_TIMESTAMP")
NOTE: This answer obviously defeats the purpose of SSL and should be used sparingly as a last resort.
For those having issues with scripts that download scripts that download scripts and want a quick fix, create a file called ~/.curlrc
With the contents
--insecure
This will cause curl to ignore SSL certificate problems by default.
Make sure you delete the file when done.
UPDATE
12 days later I got notified of an upvote on this answer, which made me go "Hmmm, did I follow my own advice remember to delete that .curlrc
?", and discovered I hadn't. So that really underscores how easy it is to leave your curl insecure by following this method.
I had similar issue with the index.html being cached by the browser or more tricky by middle cdn/proxies (F5 will not help you).
I looked for a solution which verifies 100% that the client has the latest index.html version, luckily I found this solution by Henrik Peinar:
https://blog.nodeswat.com/automagic-reload-for-clients-after-deploy-with-angular-4-8440c9fdd96c
The solution solve also the case where the client stays with the browser open for days, the client checks for updates on intervals and reload if newer version deployd.
The solution is a bit tricky but works like a charm:
ng cli -- prod
produces hashed files with one of them called main.[hash].jsSince Henrik Peinar solution was for angular 4, there were minor changes, I place also the fixed scripts here:
VersionCheckService :
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Injectable()
export class VersionCheckService {
// this will be replaced by actual hash post-build.js
private currentHash = '{{POST_BUILD_ENTERS_HASH_HERE}}';
constructor(private http: HttpClient) {}
/**
* Checks in every set frequency the version of frontend application
* @param url
* @param {number} frequency - in milliseconds, defaults to 30 minutes
*/
public initVersionCheck(url, frequency = 1000 * 60 * 30) {
//check for first time
this.checkVersion(url);
setInterval(() => {
this.checkVersion(url);
}, frequency);
}
/**
* Will do the call and check if the hash has changed or not
* @param url
*/
private checkVersion(url) {
// timestamp these requests to invalidate caches
this.http.get(url + '?t=' + new Date().getTime())
.subscribe(
(response: any) => {
const hash = response.hash;
const hashChanged = this.hasHashChanged(this.currentHash, hash);
// If new version, do something
if (hashChanged) {
// ENTER YOUR CODE TO DO SOMETHING UPON VERSION CHANGE
// for an example: location.reload();
// or to ensure cdn miss: window.location.replace(window.location.href + '?rand=' + Math.random());
}
// store the new hash so we wouldn't trigger versionChange again
// only necessary in case you did not force refresh
this.currentHash = hash;
},
(err) => {
console.error(err, 'Could not get version');
}
);
}
/**
* Checks if hash has changed.
* This file has the JS hash, if it is a different one than in the version.json
* we are dealing with version change
* @param currentHash
* @param newHash
* @returns {boolean}
*/
private hasHashChanged(currentHash, newHash) {
if (!currentHash || currentHash === '{{POST_BUILD_ENTERS_HASH_HERE}}') {
return false;
}
return currentHash !== newHash;
}
}
change to main AppComponent:
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
constructor(private versionCheckService: VersionCheckService) {
}
ngOnInit() {
console.log('AppComponent.ngOnInit() environment.versionCheckUrl=' + environment.versionCheckUrl);
if (environment.versionCheckUrl) {
this.versionCheckService.initVersionCheck(environment.versionCheckUrl);
}
}
}
The post-build script that makes the magic, post-build.js:
const path = require('path');
const fs = require('fs');
const util = require('util');
// get application version from package.json
const appVersion = require('../package.json').version;
// promisify core API's
const readDir = util.promisify(fs.readdir);
const writeFile = util.promisify(fs.writeFile);
const readFile = util.promisify(fs.readFile);
console.log('\nRunning post-build tasks');
// our version.json will be in the dist folder
const versionFilePath = path.join(__dirname + '/../dist/version.json');
let mainHash = '';
let mainBundleFile = '';
// RegExp to find main.bundle.js, even if it doesn't include a hash in it's name (dev build)
let mainBundleRegexp = /^main.?([a-z0-9]*)?.js$/;
// read the dist folder files and find the one we're looking for
readDir(path.join(__dirname, '../dist/'))
.then(files => {
mainBundleFile = files.find(f => mainBundleRegexp.test(f));
if (mainBundleFile) {
let matchHash = mainBundleFile.match(mainBundleRegexp);
// if it has a hash in it's name, mark it down
if (matchHash.length > 1 && !!matchHash[1]) {
mainHash = matchHash[1];
}
}
console.log(`Writing version and hash to ${versionFilePath}`);
// write current version and hash into the version.json file
const src = `{"version": "${appVersion}", "hash": "${mainHash}"}`;
return writeFile(versionFilePath, src);
}).then(() => {
// main bundle file not found, dev build?
if (!mainBundleFile) {
return;
}
console.log(`Replacing hash in the ${mainBundleFile}`);
// replace hash placeholder in our main.js file so the code knows it's current hash
const mainFilepath = path.join(__dirname, '../dist/', mainBundleFile);
return readFile(mainFilepath, 'utf8')
.then(mainFileData => {
const replacedFile = mainFileData.replace('{{POST_BUILD_ENTERS_HASH_HERE}}', mainHash);
return writeFile(mainFilepath, replacedFile);
});
}).catch(err => {
console.log('Error with post build:', err);
});
simply place the script in (new) build folder run the script using node ./build/post-build.js
after building dist folder using ng build --prod
If you only need the indices, you could try numpy.ndindex
:

>>> [(x, y) for x, y in numpy.ndindex(a.shape)]
[(0, 0), (0, 1), (0, 2), (1, 0), (1, 1), (1, 2), (2, 0), (2, 1), (2, 2)]

In my Controller, I merely added an HttpServletResponse parameter and manually added the headers, no filter or intercept required and it works fine:
httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET, OPTIONS");
httpServletResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept, X-Auth-Token, X-Csrf-Token, WWW-Authenticate, Authorization");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "false");
httpServletResponse.setHeader("Access-Control-Max-Age", "3600");

You are really mixing together two different things.
Use dir()
, vars()
or the inspect
module to get what you are interested in (I use __builtins__
as an example; you can use any object instead).
>>> l = dir(__builtins__)
>>> d = __builtins__.__dict__
Print that dictionary however fancy you like:
>>> print l
['ArithmeticError', 'AssertionError', 'AttributeError',...
or
>>> from pprint import pprint
>>> pprint(l)
['ArithmeticError',
'AssertionError',
'AttributeError',
'BaseException',
'DeprecationWarning',
...
>>> pprint(d, indent=2)
{ 'ArithmeticError': <type 'exceptions.ArithmeticError'>,
'AssertionError': <type 'exceptions.AssertionError'>,
'AttributeError': <type 'exceptions.AttributeError'>,
...
'_': [ 'ArithmeticError',
'AssertionError',
'AttributeError',
'BaseException',
'DeprecationWarning',
...
Pretty printing is also available in the interactive debugger as a command:
(Pdb) pp vars()
{'__builtins__': {'ArithmeticError': <type 'exceptions.ArithmeticError'>,
'AssertionError': <type 'exceptions.AssertionError'>,
'AttributeError': <type 'exceptions.AttributeError'>,
'BaseException': <type 'exceptions.BaseException'>,
'BufferError': <type 'exceptions.BufferError'>,
...
'zip': <built-in function zip>},
'__file__': 'pass.py',
'__name__': '__main__'}
Please try once uninstalling from Help-->Installation details

If you have multiple Menus with Submenus, then you can go with the below solution.
HTML
<ul class="sidebar-menu" id="nav-accordion">
<li class="sub-menu">
<a href="" ng-click="hasSubMenu('dashboard')">
<i class="fa fa-book"></i>
<span>Dashboard</span>
<i class="fa fa-angle-right pull-right"></i>
</a>
<ul class="sub" ng-show="showDash">
<li><a ng-class="{ active: isActive('/dashboard/loan')}" href="#/dashboard/loan">Loan</a></li>
<li><a ng-class="{ active: isActive('/dashboard/recovery')}" href="#/dashboard/recovery">Recovery</a></li>
</ul>
</li>
<li class="sub-menu">
<a href="" ng-click="hasSubMenu('customerCare')">
<i class="fa fa-book"></i>
<span>Customer Care</span>
<i class="fa fa-angle-right pull-right"></i>
</a>
<ul class="sub" ng-show="showCC">
<li><a ng-class="{ active: isActive('/customerCare/eligibility')}" href="#/CC/eligibility">Eligibility</a></li>
<li><a ng-class="{ active: isActive('/customerCare/transaction')}" href="#/CC/transaction">Transaction</a></li>
</ul>
</li>
</ul>
There are two functions i have called first is ng-click = hasSubMenu('dashboard'). This function will be used to toggle the menu and it is explained in the code below. The ng-class="{ active: isActive('/customerCare/transaction')} it will add a class active to the current menu item.
Now i have defined some functions in my app:
First, add a dependency $rootScope which is used to declare variables and functions. To learn more about $roootScope refer to the link : https://docs.angularjs.org/api/ng/service/$rootScope
Here is my app file:
$rootScope.isActive = function (viewLocation) {
return viewLocation === $location.path();
};
The above function is used to add active class to the current menu item.
$rootScope.showDash = false;
$rootScope.showCC = false;
var location = $location.url().split('/');
if(location[1] == 'customerCare'){
$rootScope.showCC = true;
}
else if(location[1]=='dashboard'){
$rootScope.showDash = true;
}
$rootScope.hasSubMenu = function(menuType){
if(menuType=='dashboard'){
$rootScope.showCC = false;
$rootScope.showDash = $rootScope.showDash === false ? true: false;
}
else if(menuType=='customerCare'){
$rootScope.showDash = false;
$rootScope.showCC = $rootScope.showCC === false ? true: false;
}
}
By default $rootScope.showDash and $rootScope.showCC are set to false. It will set the menus to closed when page is initially loaded. If you have more than two submenus add accordingly.
hasSubMenu() function will work for toggling between the menus. I have added a small condition
if(location[1] == 'customerCare'){
$rootScope.showCC = true;
}
else if(location[1]=='dashboard'){
$rootScope.showDash = true;
}
it will remain the submenu open after reloading the page according to selected menu item.
I have defined my pages like:
$routeProvider
.when('/dasboard/loan', {
controller: 'LoanController',
templateUrl: './views/loan/view.html',
controllerAs: 'vm'
})
You can use isActive() function only if you have a single menu without submenu. You can modify the code according to your requirement. Hope this will help. Have a great day :)
A far more common answer is that you have some error that is getting appended to whatever your compressing. The solution is to set display_errors = Off
in your php.ini file (Check in your terminal if it's On by running php --info
and look for "display_errors")
That should do it. And, how do you discover what errors you're actually? Check your PHP error logs whenever you hit that route/page.
Good luclk!
I made a simple JQuery plugin for this if anyone is interested.
It is under Account -> Application Settings, click on your application's profile, then go to Edit Application.
There are basically two alternatives, using setLength(0)
to reset the StringBuilder or creating a new one in each iteration. Both can have pros and cons depending on the usage.
If you know the expected capacity of the StringBuilder beforehand, creating a new one each time should be just as fast as setting a new length. It will also help the garbage collector, since each StringBuilder will be relatively short-lived and the gc is optimized for that.
When you don't know the capacity, reusing the same StringBuilder might be faster. Each time you exceed the capacity when appending, a new backing array has to be allocated and the previous content has to be copied. By reusing the same StringBuilder, it will reach the needed capacity after some iterations and there won't be any copying thereafter.
Fastest way is this :
public static string GetHash(string input)
{
return string.Join("", (new SHA1Managed().ComputeHash(Encoding.UTF8.GetBytes(input))).Select(x => x.ToString("X2")).ToArray());
}
For Small character output use x2
in replace of of X2
I know this is an old thread, however I noticed that no one mentioned the underline option, which can remove the underlines under the column headings.
set pagesize 50000--50k is the max as of 12c
set linesize 10000
set trimspool on --remove trailing blankspaces
set underline off --remove the dashes/underlines under the col headers
set colsep ~

Make sure your refs for pushing are correct. This tutorial is pretty great, right from the documentation:
http://wiki.eclipse.org/EGit/User_Guide#GitHub_Tutorial
You can clone directly from GitHub, you choose where you clone that repository. And when you import that repository to Eclipse, you choose what refspec to push into upstream.
Click on the Git Repository workspace view, and make sure your remote refs are valid. Make sure you are pointing to the right local branch and pushing to the correct remote branch.
you use the scrollTop attribute
var position = document.getElementById('id').scrollTop;
class CountryListView(ListView):
model = Country
def render_to_response(self, context, **response_kwargs):
return HttpResponse(json.dumps(list(self.get_queryset().values_list('code', flat=True))),mimetype="application/json")
fixed the problem
also mimetype is important.
Yes, 1 byte does encode a character (inc spaces etc) from the ASCII set. However in data units assigned to character encoding it can and often requires in practice up to 4 bytes. This is because English is not the only character set. And even in English documents other languages and characters are often represented. The numbers of these are very many and there are very many other encoding sets, which you may have heard of e.g. BIG-5, UTF-8, UTF-32. Most computers now allow for these uses and ensure the least amount of garbled text (which usually means a missing encoding set.) 4 bytes is enough to cover these possible encodings. I byte per character does not allow for this and in use it is larger often 4 bytes per possible character for all encodings, not just ASCII. The final character may only need a byte to function or be represented on screen, but requires 4 bytes to be located in the rather vast global encoding "works".
A simple way to check if a database exists is:
SHOW DATABASES LIKE 'dbname';
If database with the name 'dbname' doesn't exist, you get an empty set. If it does exist, you get one row.
There are 3 kind of object files.
Contain machine code in a form that can be combined with other relocatable object files at link time, in order to form an executable object file.
If you have an a.c
source file, to create its object file with GCC you should run:
gcc a.c -c
The full process would be: preprocessor (cpp) would run over a.c. Its output (still source) will feed into the compiler (cc1). Its output (assembly) will feed into the assembler (as), which will produce the relocatable object file
. That file contains object code and linking (and debugging if -g
was used) metadata, and is not directly executable.
Special type of relocatable object file that can be loaded dynamically, either at load time, or at run time. Shared libraries are an example of these kinds of objects.
Contain machine code that can be directly loaded into memory (by the loader, e.g execve) and subsequently executed.
The result of running the linker over multiple relocatable object files
is an executable object file
. The linker merges all the input object files from the command line, from left-to-right, by merging all the same-type input sections (e.g. .data
) to the same-type output section. It uses symbol resolution
and relocation
.
When linking against a static library
the functions that are referenced in the input objects are copied to the final executable.
With dynamic libraries
a symbol table is created instead that will enable a dynamic linking with the library's functions/globals. Thus, the result is a partially executable object file, as it depends on the library. If the library doesn't exist, the file can no longer execute).
The linking process can be done as follows:
ld a.o -o myexecutable
The command: gcc a.c -o myexecutable
will invoke all the commands mentioned at point 1 and at point 3 (cpp -> cc1 -> as -> ld1)
1: actually is collect2, which is a wrapper over ld.
Here's a dplyr
option:
library(dplyr)
# across all columns:
df %>% filter_all(any_vars(. %in% c('M017', 'M018')))
# or in only select columns:
df %>% filter_at(vars(col1, col2), any_vars(. %in% c('M017', 'M018')))
Many frameworks like Laravel
, Django
,... run local web server that work on another port except 80.For example port 8000
is the most commen port that these local web servers use.
So when you run web servers that frameworks build them and type localhost:8000
it works well.But web server that xampp(apache)
runs it has another port.In default it has 80
that it does not need to type it in url.And if you change port you should mention it in url.
**In brief:**web server in framework is different from web server in xampp . Check the port of each server and mention it in url when you use them.
consider adding a new method to BusinessClass:
public static function fromStdClass(\stdClass $in): BusinessClass
{
$out = new self();
$reflection_object = new \ReflectionObject($in);
$reflection_properties = $reflection_object->getProperties();
foreach ($reflection_properties as $reflection_property)
{
$name = $reflection_property->getName();
if (property_exists('BusinessClass', $name))
{
$out->{$name} = $in->$name;
}
}
return $out;
}
then you can make a new BusinessClass from $stdClass:
$converted = BusinessClass::fromStdClass($stdClass);
You have to select "Refresh Dependencies" in the "Gradle" context menu that appears when you right-click the project in the Package Explorer.
This will be varchar
but should format as you need.
RIGHT('0' + LTRIM(DAY(d)), 2) + '/'
+ RIGHT('0' + LTRIM(MONTH(d)), 2) + '/'
+ LTRIM(YEAR(d)) + ' '
+ RIGHT('0' + LTRIM(DATEPART(HOUR, d)), 2) + ':'
+ RIGHT('0' + LTRIM(DATEPART(MINUTE, d)), 2) + ':'
+ RIGHT('0' + LTRIM(DATEPART(SECOND, d)), 2)
Where d
is your datetime
field or variable.
I've ran across this problem recently while trying to retrieve a null decimal from a DataTable
object from db and I haven't seen this answer here. I find this easier and shorter:
var value = rdrSelect.Field<decimal?>("ColumnName") ?? 0;
This was useful in my case since i didn't have a nullable decimal in the model, but needed a quick check against one. If the db value happens to be null, it'll just assign the default value.
This would work on your edited question !
SELECT * FROM (SELECT <Column_List>,

Assuming Column A contains the values you want to find single unique instance of, and has a Heading row I used the following formula. If you wanted it to scale with an unpredictable number of rows, you could replace A772 (where my data ended) with =ADDRESS(COUNTA(A:A),1).
=IF(COUNTIF(A5:$A$772,A5)=1,A5,"")
This will display the unique value at the LAST instance of each value in the column and doesn't assume any sorting. It takes advantage of the lack of absolutes to essentially have a decreasing "sliding window" of data to count. When the countif in the reduced window is equal to 1, then that row is the last instance of that value in the column.
Install MongoDB Community Edition for Windows.
1.Now go to Download Center.
The Download Center should display the Current Stable Release for Windows

Now create MongoDB Data Directory MongoDB requires a data directory to store all data. Open Command Prompt and paste below
md "C:\data\db" "C:\data\log"
3.Lets point server to your database directory.Type below code
mongod --dbpath="c:\data\db"
4.Now lets connect to MongoDB Type below code
mongo
5.If it is working properly Command prompt will show
[initandlisten] waiting for connections
Bingo!! You are done, Apparently it is bit confusing to use CLI, well MongoDB introduced a GUI which you can see the actual data ,
To use mongoDB GUI version Above steps must have been performed
You can see the hostname : localhost and port : 27017.
Whenever you wanted to connect to mongoDB Server , You have to open Command prompt
Type
mongod
then again start a new Command prompt and type
mongo
Keep ‘em all settings as it is in mongoDB Compass. Now click connect ,
You are in !! Easy .. isn’t it?
