I was having the same problem while running bulk tests for an assignment. Turns out when I relocated some iostream operations (printing to console) from class constructor to a method in class it was solved.
I assume it was something to do with iostream manipulations in the constructor.
Here is the fix:
// Before
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {
cout << "Some text I was printing.." << endl;
};
// After
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {
};
Please feel free to explain more what the error is behind the scenes since it goes beyond my cpp knowledge.
With the Jetbrains Anko library, you can use the doAsync{..} method to automatically execute database calls. This takes care of the verbosity problem you seemed to have been having with mcastro's answer.
Example usage:
doAsync {
Application.database.myDAO().insertUser(user)
}
I use this frequently for inserts and updates, however for select queries I reccommend using the RX workflow.
Exception code 0xc0000005
is an Access Violation. An AV at fault offset 0x00000000
means that something in your service's code is accessing a nil
pointer. You will just have to debug the service while it is running to find out what it is accessing. If you cannot run it inside a debugger, then at least install a third-party exception logger framework, such as EurekaLog or MadExcept, to find out what your service was doing at the time of the AV.
Google Firebase is Google's latest(2016) way to provide you with crash/error data on your phone. Include it in your build.gradle file :
compile 'com.google.firebase:firebase-crash:9.0.0'
Fatal crashes are logged automatically without requiring user input and you can also log non-fatal crashes or other events like so :
try
{
}
catch(Exception ex)
{
FirebaseCrash.report(new Exception(ex.toString()));
}
It's important to note that once you generate a core file you'll need to use the gdb tool to look at it. For gdb to make sense of your core file, you must tell gcc to instrument the binary with debugging symbols: to do this, you compile with the -g flag:
$ g++ -g prog.cpp -o prog
Then, you can either set "ulimit -c unlimited" to let it dump a core, or just run your program inside gdb. I like the second approach more:
$ gdb ./prog
... gdb startup output ...
(gdb) run
... program runs and crashes ...
(gdb) where
... gdb outputs your stack trace ...
I hope this helps.
For angular project bundling, I've added the below line to my pakage.json file in the scripts section.
"build-prod": "node --max_old_space_size=5120 ./node_modules/@angular/cli/bin/ng build --prod --base-href /"
Now, to bundle my code, I use npm run build-prod
instead of ng build --requiredFlagsHere
hope this helps!
A very very good document regarding this topic is Troubleshooting Guide for Java from (originally) Sun. See the chapter "Troubleshooting System Crashes" for information about hs_err_pid*
Files.
See Appendix C - Fatal Error Log
Per the guide, by default the file will be created in the working directory of the process if possible, or in the system temporary directory otherwise. A specific location can be chosen by passing in the -XX:ErrorFile product flag. It says:
If the -XX:ErrorFile= file flag is not specified, the system attempts to create the file in the working directory of the process. In the event that the file cannot be created in the working directory (insufficient space, permission problem, or other issue), the file is created in the temporary directory for the operating system.
There are a lot of answers that are now outdated. The desired way of changing the heap size for Android Studio recently changed.
Users should now create their own vmoptions file in one of the following directories;
Windows:
%USERPROFILE%\.{FOLDER_NAME}\studio64.exe.vmoptions
Mac:
~/Library/Preferences/{FOLDER_NAME}/studio.vmoptions
Linux:
~/.{FOLDER_NAME}/studio.vmoptions and/or ~/.{FOLDER_NAME}/studio64.vmoptions
The contents of the newly created *.vmoptions
file should be:
-Xms128m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCompressedOops
To increase the RAM allotment change -XmX750m
to another value.

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):
Mikhail,
The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.
Good luck with your implementation.
SIGTERM is used to restart Apache (provided that it's setup in init to auto-restart): http://httpd.apache.org/docs/2.2/stopping.html
The entries you see in the logs are almost certainly there because your provider used SIGTERM for that purpose. If it's truly crashing, not even serving static content, then that sounds like some sort of a thread/connection exhaustion issue. Perhaps a DoS that holds connections open?
Should definitely be something for your provider to investigate.
If you check Thrown
for Common Language Runtime Exception
in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.
This will probably give you some insight into what is going on.
Here is another solution for Crash Log.

I had to (on top of what mentioned here) add the following line to Runpath Search Paths under Build Settings tab:

I use the following to detect different mobile devices, viewport and screen. Works quite well for me, might be helpful to others:
var pixelRatio = window.devicePixelRatio || 1;
var viewport = {
width: window.innerWidth,
height: window.innerHeight
};
var screen = {
width: window.screen.availWidth * pixelRatio,
height: window.screen.availHeight * pixelRatio
};
var iPhone = /iPhone/i.test(navigator.userAgent);
var iPhone4 = (iPhone && pixelRatio == 2);
var iPhone5 = /iPhone OS 5_0/i.test(navigator.userAgent);
var iPad = /iPad/i.test(navigator.userAgent);
var android = /android/i.test(navigator.userAgent);
var webos = /hpwos/i.test(navigator.userAgent);
var iOS = iPhone || iPad;
var mobile = iOS || android || webos;
window.devicePixelRatio
is the ratio between physical pixels and device-independent pixels (dips) on the device.
window.devicePixelRatio
= physical pixels / dips.
More info here.
You need to write all the lines you read into the output file, even if you don't change them.
Something like:
using (var input = File.OpenText("input.txt"))
using (var output = new StreamWriter("output.txt")) {
string line;
while (null != (line = input.ReadLine())) {
// optionally modify line.
output.WriteLine(line);
}
}
If you want to perform this operation in place then the easiest way is to use a temporary output file and at the end replace the input file with the output.
File.Delete("input.txt");
File.Move("output.txt", "input.txt");
(Trying to perform update operations in the middle of text file is rather hard to get right because always having the replacement the same length is hard given most encodings are variable width.)
EDIT: Rather than two file operations to replace the original file, better to use File.Replace("input.txt", "output.txt", null)
. (See MSDN.)
The slick-slide has inner wrapping div which you can use to create spacing between slides without breaking the design:

I would suggest that the current solution is to use my package urllib2_prior_auth which solves this pretty nicely (I work on inclusion to the standard lib.
No, private fields are not inherited. The only reason is that subclass can not access them directly.
After spending hours looking for the solution to this problem, I finally struck gold by making the changes mentioned on an Eclipse Forum.
Steps:
Prerequisites: mysysgit is installed with default configuration.
1.Create the file C:/Users/Username/.ssh/config (Replace "Username" with your Windows 7 user name. (e.g. C:/Users/John/.ssh/config)) and put this in it:
Host github.com
HostName github.com
User git
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
2.Try setting up the remote repository now in Eclipse.
Cheers. It should work perfectly.
How to stop a thread created by implementing runnable interface?
There are many ways that you can stop a thread but all of them take specific code to do so. A typical way to stop a thread is to have a volatile boolean shutdown
field that the thread checks every so often:
// set this to true to stop the thread
volatile boolean shutdown = false;
...
public void run() {
while (!shutdown) {
// continue processing
}
}
You can also interrupt the thread which causes sleep()
, wait()
, and some other methods to throw InterruptedException
. You also should test for the thread interrupt flag with something like:
public void run() {
while (!Thread.currentThread().isInterrupted()) {
// continue processing
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// good practice
Thread.currentThread().interrupt();
return;
}
}
}
Note that that interrupting a thread with interrupt()
will not necessarily cause it to throw an exception immediately. Only if you are in a method that is interruptible will the InterruptedException
be thrown.
If you want to add a shutdown()
method to your class which implements Runnable
, you should define your own class like:
public class MyRunnable implements Runnable {
private volatile boolean shutdown;
public void run() {
while (!shutdown) {
...
}
}
public void shutdown() {
shutdown = true;
}
}
As long as Event_ID is Integer, do this:
INSERT INTO Table (foo, bar, Event_ID)
SELECT foo, bar, (Event_ID + 155)
FROM Table
WHERE Event_ID = "120"
Considering
$string="We have www/audio path where the audio files are stored"; //Considering the string like this
Either you can use
strstr($string, 'www/audio');
Or
$expStr=explode("www/audio",$string);
$resultString="www/audio".$expStr[1];
This is how I got rid of the error:
WebDriverException: Error forwarding the new session cannot find : {platform=WINDOWS, ensureCleanSession=true, browserName=internet explorer, version=11}
In your nodeconfig.json, the version must be a String, not an integer.
So instead of using "version": 11
use "version": "11"
(note the double quotes).

Give this link a try --> https://pypi.python.org/pypi/setuptools
I'm assuming you're on Windows (could be wrong) but if you click the green Downloads button, it should take you to a table where you can choose to download a .exe version of setuptools appropriate for your version of Python. All that eggsetup stuff should be taken care of in the executable file.
Let me know if you need more help.
The main issue is that the inner query cannot be related to your where
clause on the outer update
statement, because the where filter applies first to the table being updated before the inner subquery even executes. The typical way to handle a situation like this is a multi-table update.
Update
Competition as C
inner join (
select CompetitionId, count(*) as NumberOfTeams
from PicksPoints as p

group by CompetitionID
) as A on C.CompetitionID = A.CompetitionID
set C.NumberOfTeams = A.NumberOfTeams
Had the same issue on Iphone X. To fixed it I just add height to the container

one more, after you create user by following cmd-1, please assign read/write/root role to the user by cmd-2. then restart mongodb by cmd "mongod --auth".
The benefit of assign role to the user is you can do read/write operation by mongo shell or python/java and so on, otherwise you will meet "pymongo.errors.OperationFailure: not authorized" when you try to read/write your db.
cmd-1:
use admin
db.createUser({
user: "newUsername",
pwd: "password",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
})
cmd-2:
db.grantRolesToUser('newUsername',[{ role: "root", db: "admin" }])
Feel free to use this one:
git log --pretty="%C(Yellow)%h %C(reset)%ad (%C(Green)%cr%C(reset))%x09 %C(Cyan)%an: %C(reset)%s" -7
Note the -7
at the end, to show only the last 7 entries.
Look:
I have found that the error is sometimes caused by a missing library.
so If you install RDOC first by running
gem install rdoc
then install rails with:
gem install rails
then go back and install the devtools as mentioned before with:
1) Extract DevKit to path C:\Ruby193\DevKit
2) cd C:\Ruby192\DevKit
3) ruby dk.rb init
4) ruby dk.rb review
5) ruby dk.rb install
then try installing json
which culminate with you finally being able to run
rails new project_name
- without errors.
good luck
Why not use the JPDA and attach to the launched process from a separate debugger process ? You should be able to specify the appropriate options in Maven to launch your process with the debugging hooks enabled. This article has more information.
Maybe you're not using the latest version of a JSON for Java Library.
json-simple
has not been updated for a long time, while JSON-Java
was updated 2 month ago.
JSON-Java
can be found on GitHub, here is the link to its repo: https://github.com/douglascrockford/JSON-java
After switching the library, you can refer to my sample code down below:
public static void main(String[] args) {
String JSON = "{\"LanguageLevels\":{\"1\":\"Pocz\\u0105tkuj\\u0105cy\",\"2\":\"\\u015arednioZaawansowany\",\"3\":\"Zaawansowany\",\"4\":\"Ekspert\"}}\n";
JSONObject jsonObject = new JSONObject(JSON);
JSONObject getSth = jsonObject.getJSONObject("LanguageLevels");
Object level = getSth.get("2");
System.out.println(level);
}
And as JSON-Java
open-sourced, you can read the code and its document, they will guide you through.
Hope that it helps.

You have more than one form tags with runat="server" on your template, most probably you have one in your master page, remove one on your aspx page, it is not needed if already have form in master page file which is surrounding your content place holders.
Try to remove that tag:
<form id="formID" runat="server">
and of course closing tag:
</form>
Try This:
let categories = dictData?.value(forKeyPath: "listing_subcategories_id") as! NSMutableArray
let tempArray = NSMutableArray()
for dc in categories
{
let dictD = dc as? NSMutableDictionary
tempArray.add(dictD?.object(forKey: "subcategories_name") as! String)
}
let joinedString = tempArray.componentsJoined(by: ",")
Actually, it's because CSS defines 100% relative to the entire width of the container, including its margins, borders, and padding; that means that the space avail. to its contents is some amount smaller than 100%, unless the container has no margins, borders, or padding.
This is counter-intuitive and widely regarded by many to be a mistake that we are now stuck with. It effectively means that % dimensions are no good for anything other than a top level container, and even then, only if it has no margins, borders or padding.
Note that the text field's margins, borders, and padding are included in the CSS size specified for it - it's the container's which throw things off.
I have tolerably worked around it by using 98%, but that is a less than perfect solution, since the input fields tend to fall further short as the container gets larger.
EDIT: I came across this similar question - I've never tried the answer given, and I don't know for sure if it applies to your problem, but it seems like it will.
In C #define
is much more popular. You can use those values for declaring array sizes for example:
#define MAXLEN 5
void foo(void) {
int bar[MAXLEN];
}
ANSI C doesn't allow you to use static const
s in this context as far as I know. In C++ you should avoid macros in these cases. You can write
const int maxlen = 5;
void foo() {
int bar[maxlen];
}
and even leave out static
because internal linkage is implied by const
already [in C++ only].

When you add an object to $stateProvider.state
that object is then passed with the state. So you can add additional properties which you can read later on when needed.
Example route configuration
$stateProvider
.state('public', {
abstract: true,
module: 'public'
})
.state('public.login', {
url: '/login',
module: 'public'
})
.state('tool', {
abstract: true,
module: 'private'
})
.state('tool.suggestions', {
url: '/suggestions',
module: 'private'
});
The $stateChangeStart
event gives you acces to the toState
and fromState
objects. These state objects will contain the configuration properties.
Example check for the custom module property
$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
if (toState.module === 'private' && !$cookies.Session) {
// If logged out and transitioning to a logged in page:
e.preventDefault();
$state.go('public.login');
} else if (toState.module === 'public' && $cookies.Session) {
// If logged in and transitioning to a logged out page:
e.preventDefault();
$state.go('tool.suggestions');
};
});
I didn't change the logic of the cookies because I think that is out of scope for your question.
You can create a Helper to get you this to work more modular.
Value publicStates
myApp.value('publicStates', function(){
return {
module: 'public',
routes: [{
name: 'login',
config: {
url: '/login'
}
}]
};
});
Value privateStates
myApp.value('privateStates', function(){
return {
module: 'private',
routes: [{
name: 'suggestions',
config: {
url: '/suggestions'
}
}]
};
});
The Helper
myApp.provider('stateshelperConfig', function () {
this.config = {
// These are the properties we need to set
// $stateProvider: undefined
process: function (stateConfigs){
var module = stateConfigs.module;
$stateProvider = this.$stateProvider;
$stateProvider.state(module, {
abstract: true,
module: module
});
angular.forEach(stateConfigs, function (route){
route.config.module = module;
$stateProvider.state(module + route.name, route.config);
});
}
};
this.$get = function () {
return {
config: this.config
};
};
});
Now you can use the helper to add the state configuration to your state configuration.
myApp.config(['$stateProvider', '$urlRouterProvider',
'stateshelperConfigProvider', 'publicStates', 'privateStates',
function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
helper.config.$stateProvider = $stateProvider;
helper.process(publicStates);
helper.process(privateStates);
}]);
This way you can abstract the repeated code, and come up with a more modular solution.
Note: the code above isn't tested
Try this.
@Query("Select c from Registration c where c.place like '%'||:place||'%'")
In SQL server 2005 new datatypes were introduced: varchar(max)
and nvarchar(max)
They have the advantages of the old text type: they can contain op to 2GB of data, but they also have most of the advantages of varchar
and nvarchar
. Among these advantages are the ability to use string manipulation functions such as substring().
Also, varchar(max) is stored in the table's (disk/memory) space while the size is below 8Kb. Only when you place more data in the field, it's is stored out of the table's space. Data stored in the table's space is (usually) retrieved quicker.
In short, never use Text, as there is a better alternative: (n)varchar(max). And only use varchar(max) when a regular varchar is not big enough, ie if you expect teh string that you're going to store will exceed 8000 characters.
As was noted, you can use SUBSTRING on the TEXT datatype,but only as long the TEXT fields contains less than 8000 characters.
You can use fetch optionally with await-try-catch
let photo = document.getElementById("image-file").files[0];
let formData = new FormData();
formData.append("photo", photo);
fetch('/upload/image', {method: "POST", body: formData});
async function SavePhoto(inp)
{
let user = { name:'john', age:34 };
let formData = new FormData();
let photo = inp.files[0];
formData.append("photo", photo);
formData.append("user", JSON.stringify(user));
const ctrl = new AbortController() // timeout
setTimeout(() => ctrl.abort(), 5000);
try {
let r = await fetch('/upload/image',
{method: "POST", body: formData, signal: ctrl.signal});
console.log('HTTP response code:',r.status);
} catch(e) {
console.log('Huston we have problem...:', e);
}
}

SUMMARY
filename
formData parameter.Content-Type
to multipart/form-data
- this will be set automatically by browser./upload/image
you can use full address like http://.../upload/image
.multiple
attribute: <input multiple type=... />
, and attach all chosen files to formData in similar way (e.g. photo2=...files[2];
... formData.append("photo2", photo2);
)let user = {name:'john', age:34}
in this way: formData.append("user", JSON.stringify(user));
fetch
using AbortController
, for old approach by xhr.timeout= milisec
Assertion throws error message if first attribute is false, and the second attribute is the message to be thrown.
console.assert(condition,message);
There are many comments saying assertion does not exist in JavaScript but console.assert()
is the assert function in JavaScript
The idea of assertion is to find why/where the bug occurs.
console.assert(document.getElementById("title"), "You have no element with ID 'title'");
console.assert(document.getElementById("image"), "You have no element with ID 'image'");
Here depending on the message you can find what the bug is.
These error messages will be displayed to console in red color as if we called console.error();
You can use assertions to test your functions eg:
console.assert(myAddFunction(5,8)===(5+8),"Failed on 5 and 8");
Note the condition can be anything like !=
<
>
etc
This is commonly used to test if the newly created function works as expected by providing some test cases and is not meant for production.
To see more functions in console execute console.log(console);
Because JSON directly supports the \uxxxx
syntax the first thing that comes into my mind is:
$unicodeChar = '\u1000';
echo json_decode('"'.$unicodeChar.'"');
Another option would be to use mb_convert_encoding()
echo mb_convert_encoding('က', 'UTF-8', 'HTML-ENTITIES');
or make use of the direct mapping between UTF-16BE (big endian) and the Unicode codepoint:
echo mb_convert_encoding("\x10\x00", 'UTF-8', 'UTF-16BE');
Basend on the example of Gary Kerr and as proposed here one may create empty circles related to specified values with following code:
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.markers import MarkerStyle

If you just want to get the information of current directory, you can type:
pwd
and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.
Generally you have'got an answer now but maybe my class I created will be also helpfull. For me it solves all my requirements I have ever had in my Pyhon projects.
class GetDate:
def __init__(self, date, format="%Y-%m-%d"):
self.tz = pytz.timezone("Europe/Warsaw")
if isinstance(date, str):
date = datetime.strptime(date, format)
self.date = date.astimezone(self.tz)
def time_delta_days(self, days):
return self.date + timedelta(days=days)
def time_delta_hours(self, hours):
return self.date + timedelta(hours=hours)
def time_delta_seconds(self, seconds):
return self.date + timedelta(seconds=seconds)
def get_minimum_time(self):
return datetime.combine(self.date, time.min).astimezone(self.tz)
def get_maximum_time(self):
return datetime.combine(self.date, time.max).astimezone(self.tz)
def get_month_first_day(self):
return datetime(self.date.year, self.date.month, 1).astimezone(self.tz)
def current(self):
return self.date
def get_month_last_day(self):
lastDay = calendar.monthrange(self.date.year, self.date.month)[1]
date = datetime(self.date.year, self.date.month, lastDay)
return datetime.combine(date, time.max).astimezone(self.tz)
How to use it
self.tz = pytz.timezone("Europe/Warsaw")
- here you define Time Zone you want to use in projectGetDate("2019-08-08").current()
- this will convert your string date to time aware object with timezone you defined in pt 1. Default string format is format="%Y-%m-%d"
but feel free to change it. (eg. GetDate("2019-08-08 08:45", format="%Y-%m-%d %H:%M").current()
)GetDate("2019-08-08").get_month_first_day()
returns given date (string or object) month first dayGetDate("2019-08-08").get_month_last_day()
returns given date month last dayGetDate("2019-08-08").minimum_time()
returns given date day startGetDate("2019-08-08").maximum_time()
returns given date day endGetDate("2019-08-08").time_delta_days({number_of_days})
returns given date + add {number of days} (you can also call: GetDate(timezone.now()).time_delta_days(-1)
for yesterday)GetDate("2019-08-08").time_delta_haours({number_of_hours})
similar to pt 7 but working on hoursGetDate("2019-08-08").time_delta_seconds({number_of_seconds})
similar to pt 7 but working on secondsFor example this simple Makefile should be sufficient:
CC=gcc CFLAGS=-Wall all: program program: program.o program.o: program.c program.h headers.h clean: rm -f program program.o run: program ./program
Note there must be <tab>
on the next line after clean and run, not spaces.
UPDATE Comments below applied
skaffman seems to be giving a good answer.
another way is probably to format the XML using a commmand line utility like xmlstarlet(http://xmlstar.sourceforge.net/) and then format both the strings and then use any diff utility(library) to diff the resulting output files. I don't know if this is a good solution when issues are with namespaces.
I found an answer here well practiced, but it was still necessary to add a delay
Create the following directive:
angular.module('MyApp').directive('emitLastRepeaterElement', function() {
return function(scope) {
if (scope.$last){
scope.$emit('LastRepeaterElement');
}
}; });
Add it to your repeater as an attribute, like this:
<div ng-repeat="item in items" emit-last-repeater-element></div>
According to Radu,:
$scope.eventoSelecionado.internamento_evolucoes.forEach(ie => {mycode});
For me it works, but I still need to add a setTimeout
$scope.eventoSelecionado.internamento_evolucoes.forEach(ie => {
setTimeout(function() {
mycode
}, 100); });
If you are downloading samples from developer.chrome.com its possible that your actual folder is contained in a folder with the same name and this is creating a problem. For example your extracted sample extension named tabCapture will lool like this:
C:\Users\...\tabCapture\tabCapture
Try this:
export HTTPS_PROXY_REQUEST_FULLURI=false
solved this issue for me working behind a proxy at a company few weeks ago.
You must set CHMOD +x (execute for *.sh or *.bat files). For example, I am using macOS
cd /Users/donhuvy/Documents/tools/apache-tomcat-9.0.12/bin
sudo chmod +x *.sh
Then IntelliJ IDEA, and Apache Tomcat running or debugging just good.
try this code....
@Override

Well I did a bit of searching around the internet for you and I found this handy link.
Easiest way to find duplicate values in a JavaScript array
You can adapt the sample code that is provided in the above link, courtesy of "swilliams" to your solution.
You will need have to download InternetExplorer driver executable on your system, download it from the source (http://code.google.com/p/selenium/downloads/list) after download unzip it and put on the place of somewhere in your computer. In my example, I will place it to D:\iexploredriver.exe
Then you have write below code in your eclipse main class
System.setProperty("webdriver.ie.driver", "D:/iexploredriver.exe");
WebDriver driver = new InternetExplorerDriver();
It was hard for me to readily find specific use cases for the use of % online ,e.g. why does doing fractional modulus division or negative modulus division result in the answer that it does. Hope this helps clarify questions like this:
Modulus Division In General:
Modulus division returns the remainder of a mathematical division operation. It is does it as follows:
Say we have a dividend of 5 and divisor of 2, the following division operation would be (equated to x):
dividend = 5
divisor = 2
x = 5/2
The first step in the modulus calculation is to conduct integer division:
x_int = 5 // 2 ( integer division in python uses double slash)
x_int = 2
Next, the output of x_int is multiplied by the divisor:
x_mult = x_int * divisor x_mult = 4
Lastly, the dividend is subtracted from the x_mult
dividend - x_mult = 1
The modulus operation ,therefore, returns 1:
5 % 2 = 1
Application to apply the modulus to a fraction
Example: 2 % 5
The calculation of the modulus when applied to a fraction is the same as above; however, it is important to note that the integer division will result in a value of zero when the divisor is larger than the dividend:
dividend = 2
divisor = 5
The integer division results in 0 whereas the; therefore, when step 3 above is performed, the value of the dividend is carried through (subtracted from zero):
dividend - 0 = 2 —> 2 % 5 = 2
Application to apply the modulus to a negative
Floor division occurs in which the value of the integer division is rounded down to the lowest integer value:
import math
x = -1.1
math.floor(-1.1) = -2
y = 1.1
math.floor = 1
Therefore, when you do integer division you may get a different outcome than you expect!
Applying the steps above on the following dividend and divisor illustrates the modulus concept:
dividend: -5
divisor: 2
Step 1: Apply integer division
x_int = -5 // 2 = -3
Step 2: Multiply the result of the integer division by the divisor
x_mult = x_int * 2 = -6
Step 3: Subtract the dividend from the multiplied variable, notice the double negative.
dividend - x_mult = -5 -(-6) = 1
Therefore:
-5 % 2 = 1
The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:
XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
where xml2.Element("ID").Value == variable
select xml2).FirstOrDefault();
This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

If you're platform is Windows, I wouldn't actually recommend Python. Instead, look into Autohotkey. Trust me, I love Python, but in this circumstance a macro program is the ideal tool for the job. Autohotkey's scripting is only decent (in my opinion), but the ease of simulating input will save you countless hours. Autohotkey scripts can be "compiled" as well so you don't need the interpreter to run the script.
Also, if this is for something on the Web, I recommend iMacros. It's a firefox plugin and therefore has a much better integration with websites. For example, you can say "write 1000 'a's in this form" instead of "simulate a mouseclick at (319,400) and then press 'a' 1000 times".
For Linux, I unfortunately have not been able to find a good way to easily create keyboard/mouse macros.
Not knowing what you are trying to do, I'll share one more suggestion: Preallocate vectors of the type you want for each column, insert values into those vectors, and then, at the end, create your data.frame
.
Continuing with Julian's f3
(a preallocated data.frame
) as the fastest option so far, defined as:
# pre-allocate space
f3 <- function(n){
df <- data.frame(x = numeric(n), y = character(n), stringsAsFactors = FALSE)
for(i in 1:n){
df$x[i] <- i
df$y[i] <- toString(i)
}
df
}
Here's a similar approach, but one where the data.frame
is created as the last step.
# Use preallocated vectors
f4 <- function(n) {
x <- numeric(n)
y <- character(n)
for (i in 1:n) {
x[i] <- i
y[i] <- i
}
data.frame(x, y, stringsAsFactors=FALSE)
}
microbenchmark
from the "microbenchmark" package will give us more comprehensive insight than system.time
:
library(microbenchmark)
microbenchmark(f1(1000), f3(1000), f4(1000), times = 5)
# Unit: milliseconds
# expr min lq median uq max neval
# f1(1000) 1024.539618 1029.693877 1045.972666 1055.25931 1112.769176 5
# f3(1000) 149.417636 150.529011 150.827393 151.02230 160.637845 5
# f4(1000) 7.872647 7.892395 7.901151 7.95077 8.049581 5
f1()
(the approach below) is incredibly inefficient because of how often it calls data.frame
and because growing objects that way is generally slow in R. f3()
is much improved due to preallocation, but the data.frame
structure itself might be part of the bottleneck here. f4()
tries to bypass that bottleneck without compromising the approach you want to take.
This is really not a good idea, but if you wanted to do it this way, I guess you can try:
for (i in 1:10) {
df <- rbind(df, data.frame(x = i, y = toString(i)))
}
Note that in your code, there is one other problem:
stringsAsFactors
if you want the characters to not get converted to factors. Use: df = data.frame(x = numeric(), y = character(), stringsAsFactors = FALSE)
Here is how you would add query string parameters using HttpClient 4.2 and later:
URIBuilder builder = new URIBuilder("http://example.com/");
builder.setParameter("parts", "all").setParameter("action", "finish");
HttpPost post = new HttpPost(builder.build());
The resulting URI would look like:
http://example.com/?parts=all&action=finish
I had this same issue. The package name was wrong in two of the following three files. I manually updated the package name and everything started working again.
gen/com/example/app/BuildConfig.java
gen/com/example/app/Manifest.java
gen/com/example/app/R.java
I'm not sure what caused them to change as I've never modified these files before.
I had faced similar issue on IE10. I had a workaround by using the jQuery ajax request to retrieve data:
$.ajax({
url: YOUR_XML_FILE
aync: false,
success: function (data) {
// Store data into a variable
},
dataType: YOUR_DATA_TYPE,
complete: ON_COMPLETE_FUNCTION_CALL
});
Most SSL certificates are bound to the hostname of the machine and not the ip address.
You might get a better answer if you ask this question on serverfault.com
I don't believe that there is a formal limit here, and I'm pretty sure there isn't any hard limit specified in the RFC either, as you found.
I think that some pretty common limitations for subject lines in general (not just e-mail) are:
Obviously, you want to come up with something that is reasonable. If you're writing an e-mail client, you may want to go with something like 256 characters, and obviously test thoroughly against big commercial servers out there to make sure they serve your mail correctly.
Hope this helps!
If you're not completely attached to using "from" and "to" as your option names, it's fairly easy to implement this using getopts:
while getopts f:t: opts; do
case ${opts} in
f) FROM_VAL=${OPTARG} ;;
t) TO_VAL=${OPTARG} ;;
esac
done
getopts
is a program that processes command line arguments and conveniently parses them for you.
f:t:
specifies that you're expecting 2 parameters that contain values (indicated by the colon). Something like f:t:v
says that -v
will only be interpreted as a flag.
opts
is where the current parameter is stored. The case
statement is where you will process this.
${OPTARG}
contains the value following the parameter. ${FROM_VAL}
for example will get the value /home/kristoffer/test.png
if you ran your script like:
ocrscript.sh -f /home/kristoffer/test.png -t /home/kristoffer/test.txt
As the others are suggesting, if this is your first time writing bash scripts you should really read up on some basics. This was just a quick tutorial on how getopts
works.
What you are looking for is this:
SHOW VARIABLES;
You can modify it further like any query:
SHOW VARIABLES LIKE '%max%';
Why don't you just save/serve the CSS file as UTF-8?
nav a:hover:after {
content: "?";
}
If that's not good enough, and you want to keep it all-ASCII:
nav a:hover:after {
content: "\2193";
}
The general format for a Unicode character inside a string is \000000
to \FFFFFF
– a backslash followed by six hexadecimal digits. You can leave out leading 0
digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.
Relevant part of the CSS2 spec:
Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:
- with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
- by providing exactly 6 hexadecimal digits: "\000026B" ("&B")
In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.
If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).
- Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
The identifier "te\st" is exactly the same identifier as "test".
Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).
I guess you want to do this:
$total_rating_count = count($total_rating_count);
if ($total_rating_count > 0) // because you can't divide through zero
$avg = round($total_rating_points / $total_rating_count, 1);
I found a work around but with this I'll need to annotate each date's setter throughout the project. Is there a way in which I can specify the format while creating the ObjectMapper?
Here's what I did:
public class CustomJsonDateDeserializer extends JsonDeserializer<Date>
{
@Override
public Date deserialize(JsonParser jsonParser,
DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
String date = jsonParser.getText();
try {
return format.parse(date);
} catch (ParseException e) {
throw new RuntimeException(e);
}
}
}
And annotated each Date field's setter method with this:
@JsonDeserialize(using = CustomJsonDateDeserializer.class)
Note that you don't need semicolons in batch files. And the reason why you need to use call is that mvn itself is a batch file and batch files need to call each other with call, otherwise control does not return to the caller.
add this to ~/.bashrc:
function mkfile() {
mkdir -p "$1" && touch "$1"/"$2"
}
save and then to make it available without a reboot or logout execute: $ source ~/.bashrc
or you can just do:
$ mkdir folder && touch $_/file.txt
note that $_ = folder
They are a number of things to worry about when connecting to SQL Server on another machine.
Very often SQL Server may be running as a default instance which means you can simply specify the hostname/IP address, but you may encounter a scenario where it is running as a named instance (SQL Server Express Edition for instance). In this scenario you'll have to specify the hostname/instance name.
Replace(@"\""", "")
You have to use double-doublequotes to escape double-quotes within a verbatim string.
The compiler needs to know the size of the second dimension in your two dimensional array. For example:
void print_graph(g_node graph_node[], double weight[][5], int nodes);
check if the app is in background or foreground. This method will return true if the app is in background.
First add the GET_TASKS permission to your AndroidManifest.xml
private boolean isAppIsInBackground(Context context) {
boolean isInBackground = true;
ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT_WATCH) {
List<ActivityManager.RunningAppProcessInfo> runningProcesses = am.getRunningAppProcesses();
for (ActivityManager.RunningAppProcessInfo processInfo : runningProcesses) {
if (processInfo.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
for (String activeProcess : processInfo.pkgList) {
if (activeProcess.equals(context.getPackageName())) {
isInBackground = false;
}
}
}
}
} else {
List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);
ComponentName componentInfo = taskInfo.get(0).topActivity;
if (componentInfo.getPackageName().equals(context.getPackageName())) {
isInBackground = false;
}
}
return isInBackground;

JRockit Mission Control is becoming Java Mission Control and will be dedicated exclusively to Hotspot. If you are an Oracle customer, you can download the 5.x versions of Java Mission Control from MOS (My Oracle Support). Java Mission Control will eventually be released together with the Oracle JDK. The reason it is not yet generally available is that there are some serious limitations, especially when using the Flight Recorder. However, if you are only interested in using the JMX console, you should be golden!
SELECT IDENT_CURRENT('Table')
You can use one of these examples:
SELECT * FROM Table
WHERE ID = (
SELECT IDENT_CURRENT('Table'))
SELECT * FROM Table
WHERE ID = (
SELECT MAX(ID) FROM Table)
SELECT TOP 1 * FROM Table
ORDER BY ID DESC
But the first one will be more efficient because no index scan is needed (if you have index on Id column).
The second one solution is equivalent to the third (both of them need to scan table to get max id).
I solved the problem via using and modifying CSS variables. This way I do not have to modify the component state which causes performance issues.

/usr/sbin/host `hostname`
should do the trick. Bear in mind that it's a pretty common configuration for a solaris box to have several IP addresses, though, in which case
/usr/sbin/ifconfig -a inet | awk '/inet/ {print $2}'
will list them all
netstat -ln | awk '/^(tcp|udp)/ { split($4, a, /:/); print $1, a[2]}' | sort -u
gives you the active tcp/udp ports. Then you can use the ports with fuser -n tcp
or fuser -n udp
, as root, and supposing that fuser
is GNU fuser or has similar options.
If you need more help, let me know.
Usually, you should always have a fall back link to make sure that clients with JavaScript disabled still has some functionality. This concept is called unobtrusive JavaScript.
Example... Let's say you have the following search link:
<a href="search.php" id="searchLink">Search</a>
You can always do the following:
var link = document.getElementById('searchLink');
link.onclick = function() {
try {
// Do Stuff Here
} finally {
return false;
}
};
That way, people with JavaScript disabled are directed to search.php
while your viewers with JavaScript view your enhanced functionality.
The first 2 examples act very differently if you are REPLACING them by something. If you match on this:
str = str.replace(/^(7|8|9)/ig,'');
you would replace 7 or 8 or 9 by the empty string.
If you match on this
str = str.replace(/^[7|8|9]/ig,'');
you will replace 7
or 8
or 9
OR THE VERTICAL BAR!!!! by the empty string.
I just found this out the hard way.

CORS on ASP.NET
If you don't have access to configure IIS, you can still add the header through ASP.NET by adding the following line to your source pages:

).
You can get a list of your current environments with conda info -e
and switch to one of them using activate my_env

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.
I used CountIf below, but there is lots of different ways to check existence of a value in a range.
Public Sub test()
Dim rng As Range
Dim aNumber As Long
aNumber = 666
Set rng = Sheet5.Range("B16:B615")
If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then
rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)
Else
MsgBox aNumber & " does not exist in range " & rng.Address
End If
End Sub
ALTERNATIVE WAY
Public Sub test()
Dim rng As Range
Dim aNumber As Variant
Dim rowNum As Long
aNumber = "2gg"
Set rng = Sheet5.Range("B1:B20")
If Not IsError(Application.Match(aNumber, rng, 0)) Then
rowNum = Application.Match(aNumber, rng, 0)
MsgBox rowNum
Else
MsgBox "error"
End If
End Sub

List<string> list = new List<string>(new string[] { "cat", "Dog", "parrot", "dog", "parrot", "goat", "parrot", "horse", "goat" });
Dictionary<string, int> wordCount = new Dictionary<string, int>();
//count them all:
list.ForEach(word =>
{
string key = word.ToLower();
if (!wordCount.ContainsKey(key))
wordCount.Add(key, 0);
wordCount[key]++;
});
//remove words appearing only once:
wordCount.Keys.ToList().FindAll(word => wordCount[word] == 1).ForEach(key => wordCount.Remove(key));
Console.WriteLine(string.Format("Found {0} duplicates in the list:", wordCount.Count));
wordCount.Keys.ToList().ForEach(key => Console.WriteLine(string.Format("{0} appears {1} times", key, wordCount[key])));
You can do it by calling an Activity
's runOnUiThread
method from your thread:
activity.runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(activity, "Hello", Toast.LENGTH_SHORT).show();
}
});
You have to put a g
at the end, it stands for "global":
echo dog dog dos | sed -r 's:dog:log:g'

I was looking for a similar query where I needed to use the first day of a month in my query.
The last_day
function didn't work for me but DAYOFMONTH
came in handy.
So if anyone is looking for the same issue, the following code returns the date for first day of the current month.
SELECT DATE_SUB(CURRENT_DATE, INTERVAL DAYOFMONTH(CURRENT_DATE)-1 DAY);
Comparing a date column with the first day of the month :
select * from table_name where date between
DATE_SUB(CURRENT_DATE, INTERVAL DAYOFMONTH(CURRENT_DATE)-1 DAY) and CURRENT_DATE
Here's an easy way without ifelse
:
(a/sum(a))^(a>0)
An example:
a <- c(0, 1, 0, 0, 1, 1, 0, 1)
(a/sum(a))^(a>0)
[1] 1.00 0.25 1.00 1.00 0.25 0.25 1.00 0.25
You can use SHOW
:
SHOW max_connections;
This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf
as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf
in your current session:
RESET max_connections;
However, not applicable to this particular setting. The manual:
This parameter can only be set at server start.
To see all settings:
SHOW ALL;
There is also pg_settings
:
The view
pg_settings
provides access to run-time parameters of the server. It is essentially an alternative interface to theSHOW
andSET
commands. It also provides access to some facts about each parameter that are not directly available fromSHOW
, such as minimum and maximum values.
For your original request:
SELECT *
FROM pg_settings
WHERE name = 'max_connections';
Finally, there is current_setting()
, which can be nested in DML statements:
SELECT current_setting('max_connections');

We have to dynamically set the attribute target="_blank" and it will open it in new tab.
document.getElementsByTagName("a")[0].setAttribute('target', '_blank')
document.getElementsByTagName("a")[0].click()
If you want to open in new window, get the href link and use window.open

window.open(url, "","height=500,width=500");
Don't provide the second parameter as _blank in the above.
One risk of using the keyboard shortcut is that it requires using a non-ASCII encoding. That might be fine, but if your source is loaded by different editors in different locales, you might hit trouble somewhere along the line.
It might be safer to use either ’

The hide selector was incorrect. I hid the blocks at page load and showed the selected value. I also changed the car div id's to make it easier to append the radio button value and create the proper id selector.
<div id="myRadioGroup">

3 Cars<input type="radio" name="cars" value="3" />
<div id="car-2">

$("div div").hide();

If you need to read all values from a section in properties file in a simple manner:
Your config.cfg
file layout :
[SECTION_NAME]
key1 = value1
key2 = value2
You code:
import configparser
config = configparser.RawConfigParser()
config.read('path_to_config.cfg file')
details_dict = dict(config.items('SECTION_NAME'))
This will give you a dictionary where keys are same as in config file and their corresponding values.
details_dict
is :
{'key1':'value1', 'key2':'value2'}
Now to get key1's value :
details_dict['key1']
Putting it all in a method which reads sections from config file only once(the first time the method is called during a program run).
def get_config_dict():
if not hasattr(get_config_dict, 'config_dict'):
get_config_dict.config_dict = dict(config.items('SECTION_NAME'))
return get_config_dict.config_dict
Now call the above function and get the required key's value :
config_details = get_config_dict()
key_1_value = config_details['key1']
Generic Multi Section approach:
[SECTION_NAME_1]
key1 = value1
key2 = value2
[SECTION_NAME_2]
key1 = value1
key2 = value2
Extending the approach mentioned above, reading section by section automatically and then accessing by section name followed by key name.
def get_config_section():
if not hasattr(get_config_section, 'section_dict'):
get_config_section.section_dict = collections.defaultdict()
for section in config.sections():
get_config_section.section_dict[section] = dict(config.items(section))
return get_config_section.section_dict
To access:
config_dict = get_config_section()
port = config_dict['DB']['port']
(here 'DB' is a section name in config file and 'port' is a key under section 'DB'.)

The default access for everything in C# is "the most restricted access you could declare for that member".
So for example:
namespace MyCompany
{
class Outer
{
void Foo() {}
class Inner {}
}
}
is equivalent to
namespace MyCompany
{
internal class Outer
{
private void Foo() {}
private class Inner {}
}
}
The one sort of exception to this is making one part of a property (usually the setter) more restricted than the declared accessibility of the property itself:
public string Name
{
get { ... }
private set { ... } // This isn't the default, have to do it explicitly
}
This is what the C# 3.0 specification has to say (section 3.5.1):
Depending on the context in which a member declaration takes place, only certain types of declared accessibility are permitted. Furthermore, when a member declaration does not include any access modifiers, the context in which the declaration takes place determines the default declared accessibility.
- Namespaces implicitly have public declared accessibility. No access modifiers are allowed on namespace declarations.
- Types declared in compilation units or namespaces can have public or internal declared accessibility and default to internal declared accessibility.
- Class members can have any of the five kinds of declared accessibility and default to private declared accessibility. (Note that a type declared as a member of a class can have any of the five kinds of declared accessibility, whereas a type declared as a member of a namespace can have only public or internal declared accessibility.)
- Struct members can have public, internal, or private declared accessibility and default to private declared accessibility because structs are implicitly sealed. Struct members introduced in a struct (that is, not inherited by that struct) cannot have protected or protected internal declared accessibility. (Note that a type declared as a member of a struct can have public, internal, or private declared accessibility, whereas a type declared as a member of a namespace can have only public or internal declared accessibility.)
- Interface members implicitly have public declared accessibility. No access modifiers are allowed on interface member declarations.
- Enumeration members implicitly have public declared accessibility. No access modifiers are allowed on enumeration member declarations.
(Note that nested types would come under the "class members" or "struct members" parts - and therefore default to private visibility.)
If you want to keep it simple go ahead and try this out.
$page_number = mysqli_escape_string($con, $_GET['page']);
$count_per_page = 20;
$next_offset = $page_number * $count_per_page;
$cat =mysqli_query($con, "SELECT * FROM categories LIMIT $count_per_page OFFSET $next_offset");
while ($row = mysqli_fetch_array($cat))
$count = $row[0];
The rest is up to you. If you have result comming from two tables i suggest you try a different approach.
Add a label control to your Repeater's ItemTemplate. Handle OnItemCreated event.
ASPX
<asp:Repeater ID="rptr" runat="server" OnItemCreated="RepeaterItemCreated">
<ItemTemplate>
<div id="width:50%;height:30px;background:#0f0a0f;">
<asp:Label ID="lblSr" runat="server"
style="width:30%;float:left;text-align:right;text-indent:-2px;" />
<span
style="width:65%;float:right;text-align:left;text-indent:-2px;" >
<%# Eval("Item") %>
</span>
</div>
</ItemTemplate>
</asp:Repeater>
Code Behind:
protected void RepeaterItemCreated(object sender, RepeaterItemEventArgs e)
{
Label l = e.Item.FindControl("lblSr") as Label;
if (l != null)
l.Text = e.Item.ItemIndex + 1+"";
}
The "overhead" with cursors is merely part of the API. Cursors are how parts of the RDBMS work under the hood. Often CREATE TABLE
and INSERT
have SELECT
statements, and the implementation is the obvious internal cursor implementation.
Using higher-level "set-based operators" bundles the cursor results into a single result set, meaning less API back-and-forth.
Cursors predate modern languages that provide first-class collections. Old C, COBOL, Fortran, etc., had to process rows one at a time because there was no notion of "collection" that could be used widely. Java, C#, Python, etc., have first-class list structures to contain result sets.
The Slow Issue
In some circles, the relational joins are a mystery, and folks will write nested cursors rather than a simple join. I've seen truly epic nested loop operations written out as lots and lots of cursors. Defeating an RDBMS optimization. And running really slowly.
Simple SQL rewrites to replace nested cursor loops with joins and a single, flat cursor loop can make programs run in 100th the time. [They thought I was the god of optimization. All I did was replace nested loops with joins. Still used cursors.]
This confusion often leads to an indictment of cursors. However, it isn't the cursor, it's the misuse of the cursor that's the problem.
The Size Issue
For really epic result sets (i.e., dumping a table to a file), cursors are essential. The set-based operations can't materialize really large result sets as a single collection in memory.
Alternatives
I try to use an ORM layer as much as possible. But that has two purposes. First, the cursors are managed by the ORM component. Second, the SQL is separated from the application into a configuration file. It's not that the cursors are bad. It's that coding all those opens, closes and fetches is not value-add programming.
Extending other answers:
I found @GEverding's answer most flexible. It also works with aggregation:
test_db.js
print("name,email");
db.users.aggregate([
{ $match: {} }
]).forEach(function(user) {
print(user.name+","+user.email);
}
});
Execute the following command to export results:
mongo test_db < ./test_db.js >> ./test_db.csv
Unfortunately, it adds additional text to the CSV file which requires processing the file before we can use it:
MongoDB shell version: 3.2.10
connecting to: test_db
But we can make mongo shell stop spitting out those comments and only print what we have asked for by passing the --quiet
flag
mongo --quiet test_db < ./test_db.js >> ./test_db.csv
<application android:icon="drawable resource">
....
</application>
https://developer.android.com/guide/topics/manifest/application-element.html
You should create separate icons for all generalized screen densities, including low-, medium-, high-, and extra-high-density screens. This ensures that your icons will display properly across the range of devices on which your application can be installed...
Launcher icons should be 32-bit PNGs with an alpha channel for transparency. The finished launcher icon dimensions corresponding to a given generalized screen density are shown in the table below.
android:icon="@drawable/icon_name"
or android:icon="@mipmap/icon_name"
developer.android.com/guide says,
This attribute must be set as a reference to a drawable resource containing the image (for example "@drawable/icon").
about launcher icons android-developers.googleblog.com says,
It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density. For example, an xxxhdpi app icon can be used on the launcher for an xxhdpi device.
Dianne Hackborn from Google (Android Framework) says,
If you are building different versions of your app for different densities, you should know about the "mipmap" resource directory. This is exactly like "drawable" resources, except it does not participate in density stripping when creating the different apk targets.
<application android:name="ApplicationTitle"
android:label="@string/app_label"
android:icon="@mipmap/ic_launcher" >
Little bit more quoting this
You want to load an image for your device density and you are going to use it "as is", without changing its actual size. In this case you should work with drawables and Android will give you the best fitting image.
You want to load an image for your device density, but this image is going to be scaled up or down. For instance this is needed when you want to show a bigger launcher icon, or you have an animation, which increases image's size. In such cases, to ensure best image quality, you should put your image into mipmap folder. What Android will do is, it will try to pick up the image from a higher density bucket instead of scaling it up. This will increase sharpness (quality) of the image.
Fore more you can read mipmap vs drawable folders

I use json_decode($response->getBody())

.
I suspect this might be a casualty of PSR-7 compliance.
I think that the fastest way to do this is to just clone the node, which will remove all event listeners:
var old_element = document.getElementById("btn");
var new_element = old_element.cloneNode(true);
old_element.parentNode.replaceChild(new_element, old_element);
Just be careful, as this will also clear event listeners on all child elements of the node in question, so if you want to preserve that you'll have to resort to explicitly removing listeners one at a time.

overflow: scroll;

It looks like your $pdo
variable is not initialized.
I can't see in the code you've uploaded where you are initializing it.
Make sure you create a new PDO object in the global scope
before calling the class methods. (You should declare it in the global scope because of how you implemented the methods inside the Category class).
$pdo = new PDO('mysql:host=localhost;dbname=test', $user, $pass);
You can use diff
tool in linux to compare two files. You can use --changed-group-format and --unchanged-group-format options to filter required data.
Following three options can use to select the relevant group for each option:
'%<' get lines from FILE1
'%>' get lines from FILE2
'' (empty string) for removing lines from both files.
E.g: diff --changed-group-format="%<" --unchanged-group-format="" file1.txt file2.txt
[root@vmoracle11 tmp]# cat file1.txt
test one
test two
test three
test four
test eight
[root@vmoracle11 tmp]# cat file2.txt
test one
test three
test nine
[root@vmoracle11 tmp]# diff --changed-group-format='%<' --unchanged-group-format='' file1.txt file2.txt
test two
test four
test eight
I know its late but I think you can try like this
$("#multipledpdwn").on("select2:select select2:unselect", function (e) {
//this returns all the selected item
var items= $(this).val();
//Gets the last selected item
var lastSelectedItem = e.params.data.id;
})
Hope it may help some one in future.

echo 'alert("review your answer")';
echo 'window.location= "index.php"';
To:
echo 'alert("review your answer");';

Whenever you use "new", that is, attach an address to a pointer, or to say, you claim space on the heap, you need to "delete" it.
1.yes, when you delete something, the destructor is called.
2.When the destructor of the linked list is called, it's objects' destructor is called. But if they are pointers, you need to delete them manually.
3.when the space is claimed by "new".

I've developed the following jQuery plugin for client side ease of use:
(function ($, undefined) {
"using strict";
$.FooGetJSON = function (url, data, success, error) {
/// <summary>
/// **********************************************************
/// * UNIK GET JSON JQUERY PLUGIN. *
/// **********************************************************
/// This plugin is a wrapper for jQuery.getJSON.
/// The reason is that jQuery.getJSON success handler doesn't provides access to the JSON object returned from the url
/// when a HTTP status code different from 200 is encountered. However, please note that whether there is JSON
/// data or not depends on the requested service. if there is no JSON data (i.e. response.responseText cannot be
/// parsed as JSON) then the data parameter will be undefined.
///
/// This plugin solves this problem by providing a new error handler signature which includes a data parameter.
/// Usage of the plugin is much equal to using the jQuery.getJSON method. Handlers can be added etc. However,
/// the only way to obtain an error handler with the signature specified below with a JSON data parameter is
/// to call the plugin with the error handler parameter directly specified in the call to the plugin.
///
/// success: function(data, textStatus, jqXHR)
/// error: function(data, jqXHR, textStatus, errorThrown)
///
/// Example usage:
///
/// $.FooGetJSON('/foo', { id: 42 }, function(data) { alert('Name :' + data.name); }, function(data) { alert('Error: ' + data.message); });
/// </summary>
// Call the ordinary jQuery method
var jqxhr = $.getJSON(url, data, success);
// Do the error handler wrapping stuff to provide an error handler with a JSON object - if the response contains JSON object data
if (typeof error !== "undefined") {
jqxhr.error(function(response, textStatus, errorThrown) {
try {
var json = $.parseJSON(response.responseText);
error(json, response, textStatus, errorThrown);
} catch(e) {
error(undefined, response, textStatus, errorThrown);
}
});
}
// Return the jQueryXmlHttpResponse object
return jqxhr;
};
})(jQuery);
What do I get from all this? The final result is that
Client side example:
var success = function(data) {
alert(data.myjsonobject.foo);
};
var onError = function(data) {
var message = "Error";
if(typeof data !== "undefined")
message += ": " + data.message;
alert(message);
};
$.FooGetJSON(url, params, onSuccess, onError);
Comments are most welcome! I'll probably blog about this solution some day...
From the Javadoc:
The EAGER strategy is a requirement on the persistence provider runtime that data must be eagerly fetched. The LAZY strategy is a hint to the persistence provider runtime that data should be fetched lazily when it is first accessed.
E.g., eager is more proactive than lazy. Lazy only happens on first use (if the provider takes the hint), whereas with eager things (may) get pre-fetched.
Because that gtab82 table isn't in your FROM or JOIN clause. You refer gtab82 table in these cases: gtab82.memno and gtab82.memacid
There is a simple solution to this problem using this library. I store an instance of the CallRecord class in MyService.class. When the service is first initialized, the following code is executed:
public class MyService extends Service {
public static CallRecord callRecord;
@Override
public void onCreate() {
super.onCreate();
callRecord = new CallRecord.Builder(this)
.setRecordFileName("test")
.setRecordDirName("Download")
.setRecordDirPath(Environment.getExternalStorageDirectory().getPath()) // optional & default value
.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB) // optional & default value
.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB) // optional & default value
.setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION) // optional & default value
.setShowSeed(false) // optional, default=true ->Ex: RecordFileName_incoming.amr || RecordFileName_outgoing.amr
.build();
callRecord.enableSaveFile();
callRecord.startCallReceiver();
}
@Override
public void onDestroy() {
super.onDestroy();
callRecord.stopCallReceiver();
}
}
Next, do not forget to specify permissions in the manifest. (I may have some extras here, but keep in mind that some of them are necessary only for newer versions of Android)
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.PROCESS_INCOMING_CALLS" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Also it is crucial to request some permissions at the first start of the application. A guide is provided here.
If my code doesn't work, alternative code can be found here. I hope I helped you.
<div id="foo">hello world!</div>
<img src="zoom.png" id="click_me" />
JS
$('#click_me').click(function(){
$('#foo').css({
'background-color':'red',
'color':'white',
'font-size':'44px'
});
});
You can use a post-commit hook.
Put the post-commit hook script in the hooks
folder, create a wget_folder
in your C:\ drive, and put the wget.exe
file in this folder.
Add the following code in the file called post-commit.bat
SET REPOS=%1
SET REV=%2
FOR /f "tokens=*" %%a IN (
'svnlook uuid %REPOS%'
) DO (
SET UUID=%%a
)
FOR /f "tokens=*" %%b IN (
'svnlook changed --revision %REV% %REPOS%'
) DO (
SET POST=%%b
)
echo %REPOS% ----- 1>&2
echo %REV% -- 1>&2
echo %UUID% --1>&2
echo %POST% --1>&2
C:\wget_folder\wget ^
--header="Content-Type:text/plain" ^
--post-data="%POST%" ^
--output-document="-" ^
--timeout=2 ^
http://localhost:9090/job/Test/build/%UUID%/notifyCommit?rev=%REV%
where Test = name of the job
echo
is used to see the value and you can also add exit 2
at the end to know about the issue and whether the post-commit hook script is running or not.
If you'd like to set this globally for all users of a machine, you can create the following directory and file structures:
mkdir %windir%\Sun\Java\Deployment
Create a file deployment.config with the content:
deployment.system.config=file:///c:/windows/Sun/Java/Deployment/deployment.properties
deployment.system.config.mandatory=TRUE
Create a file deployment.properties
deployment.user.security.exception.sites=C\:/WINDOWS/Sun/Java/Deployment/exception.sites
Create a file exception.sites
http://example1.com
http://example2.com/path/to/specific/directory/
Reference https://blogs.oracle.com/java-platform-group/entry/upcoming_exception_site_list_in
In your example, the variable a
is just a reference to an instance of a string object. When you say a = "ty"
, you are not actually changing the string object, but rather pointing the reference at an entirely different instance of the string class.

Quote from this link-
If you want to find and print the top 10 largest files names (not directories) in a particular directory and its sub directories
$ find . -printf '%s %p\n'|sort -nr|head
To restrict the search to the present directory use "-maxdepth 1" with find.
$ find . -maxdepth 1 -printf '%s %p\n'|sort -nr|head
And to print the top 10 largest "files and directories":
$ du -a . | sort -nr | head
** Use "head -n X" instead of the only "head" above to print the top X largest files (in all the above examples)
I found a combination of the first two answers gave me what I needed. I used the CurrentCellDirtyStateChanged event and inspected the EditedFormattedValue.
private void dgv_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
DataGridView dgv = (DataGridView)sender;
DataGridViewCell cell = dgv.CurrentCell;
if (cell.RowIndex >= 0 && cell.ColumnIndex == 3) // My checkbox column
{
// If checkbox checked, copy value from col 1 to col 2
if (dgv.Rows[cell.RowIndex].Cells[cell.ColumnIndex].EditedFormattedValue != null && dgv.Rows[cell.RowIndex].Cells[cell.ColumnIndex].EditedFormattedValue.Equals(true))
{
dgv.Rows[cell.RowIndex].Cells[1].Value = dgv.Rows[cell.RowIndex].Cells[2].Value;
}
}
}
Starting with Google Play 4.9, the app info display has been changed and the promo graphic is displayed at the top.
The promo graphic will be required soon.
The promo text has turned into a short description and is now shown on the main info page, before the user presses it to view the full description.
You put
registerReceiver(receiver, new IntentFilter("android.bleutooth.device.action.UUID"));
with "bluetooth" spelled "bleutooth".
Not that it is ultra important, but using can also be used to change resources on the fly. Yes disposable as mentioned earlier, but perhaps specifically you don't want the resources they mismatch with other resources during the rest of your execution. So you want to dispose of it so it doesn't interfere elsewhere.
In this part of your SP:
IF @DateFirst <> '' and @DateLast <> ''
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + @DateFirst
+ ' and convert (Date,DateLog) <=''' + @DateLast
you are trying to concatenate strings and datetimes.
As the datetime
type has higher priority than varchar
/nvarchar
, the +
operator, when it happens between a string and a datetime, is interpreted as addition, not as concatenation, and the engine then tries to convert your string parts (' or convert (Date,DateLog) >= '''
and others) to datetime or numeric values. And fails.
That doesn't happen if you omit the last two parameters when invoking the procedure, because the condition evaluates to false and the offending statement isn't executed.
To amend the situation, you need to add explicit casting of your datetime variables to strings:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst)
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast)
You'll also need to add closing single quotes:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst) + ''''
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast) + ''''
If you do not want to block things and also not want to use multi threading, here is the solution for you: https://msdn.microsoft.com/en-us/library/system.timers.timer(v=vs.110).aspx
The UI Thread is not blocked and the timer waits for 2 seconds before doing something.
Here is the code coming from the link above:
// Create a timer with a two second interval.
aTimer = new System.Timers.Timer(2000);
// Hook up the Elapsed event for the timer.
aTimer.Elapsed += OnTimedEvent;
aTimer.Enabled = true;
Console.WriteLine("Press the Enter key to exit the program... ");
Console.ReadLine();
Console.WriteLine("Terminating the application...");
As of AngularJS 1.2 there's a directive called ng-repeat-start
that does exactly what you ask for. See my answer in this question for a description of how to use it.
I have seen all answers. I want tell most robust way now a day. That will make you communicate between Activity - Service - Dialog - Fragments
(Everything).
This lib which i am using in my projects has great features related to messaging.
EventBus in 3 steps
Define events:
public static class MessageEvent { /* Additional fields if needed */ }
Prepare subscribers:
Declare and annotate your subscribing method, optionally specify a thread mode:
@Subscribe(threadMode = ThreadMode.MAIN)
public void onMessageEvent(MessageEvent event) {/* Do something */};
Register and unregister your subscriber. For example on Android, activities and fragments should usually register according to their life cycle:
@Override
public void onStart() {
super.onStart();
EventBus.getDefault().register(this);
}
@Override
public void onStop() {
super.onStop();
EventBus.getDefault().unregister(this);
}
Post events:
EventBus.getDefault().post(new MessageEvent());
Just add this dependency in your app level gradle
compile 'org.greenrobot:eventbus:3.1.1'
You will generate them once, but update them if you need a new feature or something from a plugin which in turn needs a newer gradle version.
Easiest way to update: as of Gradle 2.2 you can just download and extract the complete or binary Gradle distribution, and run:
$ <pathToExpandedZip>/bin/gradle wrapper
No need to define a task, though you probably need some kind of build.gradle
file.
This will update or create the gradlew
and gradlew.bat
wrapper as well as gradle/wrapper/gradle-wrapper.properties
and the gradle-wrapper.jar
to provide the current version of gradle, wrapped.
Those are all part of the wrapper.
Some build.gradle
files reference other files or files in subdirectories which are sub projects or modules. It gets a bit complicated, but if you have one project you basically need the one file.
settings.gradle
handles project, module and other kinds of names and settings, gradle.properties
configures resusable variables for your gradle files if you like and you feel they would be clearer that way.
I have found a new workaround, different from any other that I have seen, by disabling the native iOS zoom, and instead implementing zoom functionality in JavaScript.
An excellent background on the various other solutions to the zoom/orientation problem is by Sérgio Lopes: A fix to the famous iOS zoom bug on orientation change to portrait.

// Without zoomfix focus, after changing orientation and zoom a few times, the iOS viewport scale functionality sometimes locks up (and completely stops working).

It could be improved, but for my needs it avoids the major drawbacks that occur with all the other solutions I have seen. So far I have only tested it using mobile Safari on an iPad 2 with iOS4.
The focus()/blur() is a workaround to prevent the occasional lockup of the zoom functionality which can occur after changing orientation and zooming a few times.
Setting the document.body.style forces a full screen repaint, which avoids an occasional intermittent problems where the repaint badly fails after zoom.
If you want to round the decimal, look at Math.Round()
If Table variable has large data, then instead of table variable(@table) create temp table (#table).table variable doesn't allow to create index after insert.
CREATE TABLE #Table(C1 int,
C2 NVarchar(100) , C3 varchar(100)
UNIQUE CLUSTERED (c1)
);
Create table with unique clustered index
Insert data into Temp "#Table" table
Create non clustered indexes.
CREATE NONCLUSTERED INDEX IX1 ON #Table (C2,C3);
You can do it in in-place by doing only one pass:
function transpose(arr,arrLen) {
for (var i = 0; i < arrLen; i++) {
for (var j = 0; j <i; j++) {
//swap element[i,j] and element[j,i]
var temp = arr[i][j];
arr[i][j] = arr[j][i];
arr[j][i] = temp;
}

This is an old question, but nobody seems to have shown the clear easy way (the closest was edW). I used C# to test this, but there's nothing in this example that couldn't be done easily in C.
void PrintBinary(string prompt, int num, int pad = 8)
{
Debug.WriteLine($"{prompt}: {Convert.ToString(num, 2).PadLeft(pad, '0')}");
}
int ReverseBits(int num)
{
int result = 0;
int saveBits = num;
for (int i = 1; i <= 8; i++)
{
// Move the result one bit to the left
result = result << 1;
//PrintBinary("saveBits", saveBits);
// Extract the right-most bit
var nextBit = saveBits & 1;
//PrintBinary("nextBit", nextBit, 1);
// Add our extracted bit to the result
result = result | nextBit;
//PrintBinary("result", result);
// We're done with that bit, rotate it off the right
saveBits = saveBits >> 1;
//Debug.WriteLine("");
}
return result;
}
void PrintTest(int nextNumber)
{
var result = ReverseBits(nextNumber);
Debug.WriteLine("---------------------------------------");
PrintBinary("Original", nextNumber);
PrintBinary("Reverse", result);
}
void Main()
{
// Calculate the reverse for each number between 1 and 255
for (int x = 250; x < 256; x++)
PrintTest(x);
}
I tried this to fix access issues to an IIS website, which manifested as something like the following in the Event Logs ? Windows ? Application:

In the end I had to give the Windows Everyone

You can try this instead
var myu = document.getElementById('myu').value;
var myp = document.getElementById('myp').value;
window.opener.location.href='myurl.php?myu='+ myu +'&myp='+ myp;
Note: Do not use this method to pass sensitive information like username, password.
You can use this command:
document.getElementById('iframeid').contentWindow.print();
This command basically is the same as window.print(), but as the window we would like to print is in the iframe, we first need to obtain an instance of that window as a javascript object.
So, in reference to that iframe, we first obtain the iframe by using it's id, and then it's contentWindow returns a window(DOM) object. So, we are able to directly use the window.print() function on this object.

You can use cut
:
cut -c N- file.txt > new_file.txt
-c:
characters
file.txt:
input file
new_file.txt:
output file
N-:
Characters from N to end to be cut and output to the new file.
Can also have other args like: 'N' , 'N-M', '-M' meaning nth character, nth to mth character, first to mth character respectively.
This will perform the operation to each line of the input file.
If you didn't want to edit the layer of a UIView, you could always embed the view within another view. The parent view would have its background color set to the border color. It would also be slightly larger, depending upon how wide you want the border to be.
Of course, this only works if your view isn't transparent and you only want a single border color. The OP wanted the border in the view itself, but this may be a viable alternative.
I had a similar problem. If all you want is for some info to be displayed when you hover over a marker, instead of clicking it, then I found that a good alternative to using an info Window was to set a title on the marker. That way whenever you hover the mouse over the marker the title displays like an ALT tag. 'marker.setTitle('Marker '+id);' It removes the need to create a listener for the marker too

I'm afraid the DateTimePicker control doesn't have the ability to do those things. It's a pretty basic (and frustrating!) control. Your best option may be to find a third-party control that does what you want.
For the option of typing the date and time manually, you could build a custom component with a TextBox/DateTimePicker combination to accomplish this, and it might work reasonably well, if third-party controls are not an option.
For anyone struggling with this problem in the now (Feb 2020), the following Medium post was crucial to overcoming it for us.
https://medium.com/@ttulka/spring-http-message-converters-customizing-770814eb2b55
In our case, the app uses @EnableWebMvc and would break if removed so, the section on 'The Life without Spring Boot' was critical. Here's what ended up solving this for us. It allows us to still consume and produce JSON and XML as well as format our datetime during serialization to suit the app's needs.
@Configuration
@ComponentScan("com.company.branch")
@EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
converters.add(0, new MappingJackson2XmlHttpMessageConverter(
new Jackson2ObjectMapperBuilder()
.defaultUseWrapper(false)
.createXmlMapper(true)
.simpleDateFormat("yyyy-mm-dd'T'HH:mm:ss'Z'")
.build()
));
converters.add(1, new MappingJackson2HttpMessageConverter(
new Jackson2ObjectMapperBuilder()
.build()
));
}
}
Use Arrays.sort
and then take the middle element (in case the number n
of elements in the array is odd) or take the average of the two middle elements (in case n
is even).
public static long median(long[] l)
{
Arrays.sort(l);
int middle = l.length / 2;
if (l.length % 2 == 0)
{
long left = l[middle - 1];
long right = l[middle];
return (left + right) / 2;
}
else
{
return l[middle];
}
}
Here are some examples:
@Test
public void evenTest()
{
long[] l = {
5, 6, 1, 3, 2
};
Assert.assertEquals((3 + 4) / 2, median(l));
}
@Test
public oddTest()
{
long[] l = {
5, 1, 3, 2, 4
};
Assert.assertEquals(3, median(l));
}
And in case your input is a Collection
, you might use Google Guava to do something like this:
public static long median(Collection<Long> numbers)
{
return median(Longs.toArray(numbers)); // requires import com.google.common.primitives.Longs;
}
Does GitHub have this social feature?
If the commit email is kept private, GitHub now (July 2020) proposes:
Users and organizations can now add Twitter usernames to their GitHub profiles
You can now add your Twitter username to your GitHub profile directly from your profile page, via profile settings, and also the REST API.
We've also added the latest changes:
- Organization admins can now add Twitter usernames to their profile via organization profile settings and the REST API.
- All users are now able to see Twitter usernames on user and organization profiles, as well as via the REST and GraphQL APIs.
- When sponsorable maintainers and organizations add Twitter usernames to their profiles, we'll encourage new sponsors to include that Twitter username when they share their sponsorships on Twitter.
That could be a workaround to leave a message to a GitHub user.

pip <command> --user
changes the scope of the current pip command to work on the current user account's local python package install location, rather than the system-wide package install location, which is the default.
This only really matters on a multi-user machine. Anything installed to the system location will be visible to all users, so installing to the user location will keep that package installation separate from other users (they will not see it, and would have to install it themselves separately to use it). Because there can be version conflicts, installing a package with dependencies needed by other packages can cause problems, so it's best not to push all packages a given user uses to the system install location.
--user
location. It will be installed to a different folder, that may or may not need to be added to the path, depending on the package and how it's used (many packages install command-line tools that must be on the path to run from a shell).--user
is preferred to using root/sudo or requiring administrator installation and affecting the Python environment of every user, except in cases of general packages that the administrator wants to make available to all users by default.
apt
, rather than pip
.venv
command in the Python VENV docs.The --user
option in an active venv/virtualenv environment will install to the local user python location (same as without a virtual environment).
Packages are installed to the virtual environment by default, but if you use --user
it will force it to install outside the virtual environments, in the users python script directory (in Windows, this currently is c:\users\<username>\appdata\roaming\python\python37\scripts
for me with Python 3.7).
However, you won't be able to access a system or user install from within virtual environment (even if you used --user
while in a virtual environment).
If you install a virtual environment with the --system-site-packages
argument, you will have access to the system script folder for python. I believe this included the user python script folder as well, but I'm unsure. However, there may be unintended consequences for this and it is not the intended way to use virtual environments.
You can find the location of the user install folder for python with python -m site --user-base
. I'm finding conflicting information in Q&A's, the documentation and actually using this command on my PC as to what the defaults are, but they are underneath the user home directory (~
shortcut in *nix, and c:\users\<username>
typically for Windows).
The --user
option is not a valid for every command. For example pip uninstall
will find and uninstall packages wherever they were installed (in the user folder, virtual environment folder, etc.) and the --user
option is not valid.
Things installed with pip install --user
will be installed in a local location that will only be seen by the current user account, and will not require root access (on *nix) or administrator access (on Windows).
The --user
option modifies all pip
commands that accept it to see/operate on the user install folder, so if you use pip list --user
it will only show you packages installed with pip install --user
.

If you want to understand how excatly laravel works you can review the complete class on Github: https://github.com/illuminate/hashing/blob/master/BcryptHasher.php
But basically there are Three PHP methods involved on that:
$pasword = 'user-password';
// To create a valid password out of laravel Try out!
$cost=10; // Default cost
$password = password_hash($pasword, PASSWORD_BCRYPT, ['cost' => $cost]);
// To validate the password you can use
$hash = '$2y$10$NhRNj6QF.Bo6ePSRsClYD.4zHFyoQr/WOdcESjIuRsluN1DvzqSHm';
if (password_verify($pasword, $hash)) {
echo 'Password is valid!';
} else {
echo 'Invalid password.';
}
//Finally if you have a $hash but you want to know the information about that hash.
print_r( password_get_info( $password_hash ));
The hashed password is same as laravel 5.x bcrypt password. No need to give salt and cost, it will take its default values.
Those methods has been implemented in the laravel class, but if you want to learn more please review the official documentation: http://php.net/manual/en/function.password-hash.php
you have to be careful here not to miss the dates when in the loop a better solution would be.
this gives you the first date of startdate and use it in the loop before incrementing it and it will process all the dates including the last date of enddate hence <= enddate.
so the above answer is the correct one.
while (startdate <= enddate)
{
// do something with the startdate
startdate = startdate.adddays(interval);
}
Here are the commands to restore the old behavior:
# create a script that calls launchctl iterating through /etc/launchd.conf
echo '#!/bin/sh
while read line || [[ -n $line ]] ; do launchctl $line ; done < /etc/launchd.conf;
' > /usr/local/bin/launchd.conf.sh
# make it executable
chmod +x /usr/local/bin/launchd.conf.sh
# launch the script at startup
echo '<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

</array>
<key>RunAtLoad</key>

</dict>
</plist>
' > /Library/LaunchAgents/launchd.conf.plist
Now you can specify commands like setenv JAVA_HOME /Library/Java/Home
in /etc/launchd.conf
.

In Visual Studio 2010 and above, you now have the ability to apply a transformation to your web.config depending on the build configuration.
When creating a web.config, you can expand the file in the solution explorer, and you will see two files:
They contain transformation code that can be used to
See Web.config Transformation Syntax for Web Application Project Deployment on MSDN for more information.
It is also possible, albeit officially unsupported, to apply the same kind of transformation to an non web application app.config
file. See Phil Bolduc blog concerning how to modify your project file to add a new task to msbuild.
This is a long withstanding request on the Visual Studio Uservoice.
An extension for Visual Studio 2010 and above, "SlowCheetah," is available to take care of creating transform for any config file. Starting with Visual Studio 2017.3, SlowCheetah has been integrated into the IDE and the code base is being managed by Microsoft. This new version also support JSON transformation.
As pointed by @EmJiHash PercentRelativeLayout is deprecated in API level 26.0.0
Below quoting google comment:
This class was deprecated in API level 26.0.0. consider using ConstraintLayout and associated layouts instead. The following shows how to replicate the functionality of percentage layouts with a ConstraintLayout
Google introduced new API called android.support.percent
Then you can just specify percentage to take by view
Add compile dependency like
implementation 'com.android.support:percent:22.2.0
in that, PercentRelativeLayout is what we can do a percentage wise layout
<android.support.percent.PercentRelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
app:layout_widthPercent="50%"
app:layout_heightPercent="50%"
app:layout_marginTopPercent="25%"
app:layout_marginLeftPercent="25%"/>
</android.support.percent.PercentRelativeLayout>
Source: CodePath - UI Testing With Espresso
- Finally, we need to pull in the Espresso dependencies and set the test runner in our app build.gradle:
// build.gradle
...
android {
...
defaultConfig {
...
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
}
dependencies {
...
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2') {
// Necessary if your app targets Marshmallow (since Espresso
// hasn't moved to Marshmallow yet)
exclude group: 'com.android.support', module: 'support-annotations'
}
androidTestCompile('com.android.support.test:runner:0.5') {
// Necessary if your app targets Marshmallow (since the test runner
// hasn't moved to Marshmallow yet)
exclude group: 'com.android.support', module: 'support-annotations'
}
}
I've added that to my gradle file and the warning disappeared.
Also, if you get any other dependency listed as conflicting, such as support-annotations, try excluding it too from the androidTestCompile dependencies.

This has already been answered, but I think the simplest syntax is:
CREATE TABLE History (
ID int primary key IDENTITY(1,1) NOT NULL,
. . .
The more complicated constraint index is useful when you actually want to change the options.
By the way, I prefer to name such a column HistoryId, so it matches the names of the columns in foreign key relationships.
It will not return the name of variable but you can create dictionary from global variable easily.
class CustomDict(dict):
def __add__(self, other):
return CustomDict({**self, **other})
class GlobalBase(type):
def __getattr__(cls, key):
return CustomDict({key: globals()[key]})
def __getitem__(cls, keys):
return CustomDict({key: globals()[key] for key in keys})
class G(metaclass=GlobalBase):
pass
x, y, z = 0, 1, 2
print('method 1:', G['x', 'y', 'z']) # Outcome: method 1: {'x': 0, 'y': 1, 'z': 2}
print('method 2:', G.x + G.y + G.z) # Outcome: method 2: {'x': 0, 'y': 1, 'z': 2}
Be careful: while the string representations for .NET Guid and (RFC4122) UUID are identical, the storage format is not. .NET trades in little-endian bytes for the first three Guid
parts.
If you are transmitting the bytes (for example, as base64), you can't just use Guid.ToByteArray()
and encode it. You'll need to Array.Reverse
the first three parts (Data1-3).
I do it this way:
var rfc4122bytes = Convert.FromBase64String("aguidthatIgotonthewire==");
Array.Reverse(rfc4122bytes,0,4);
Array.Reverse(rfc4122bytes,4,2);
Array.Reverse(rfc4122bytes,6,2);
var guid = new Guid(rfc4122bytes);
See this answer for the specific .NET implementation details.
Edit: Thanks to Jeff Walker, Code Ranger, for pointing out that the internals are not relevant to the format of the byte array that goes in and out of the byte-array constructor and ToByteArray()
.

Straight from the docs
join([timeout]) Wait until the thread terminates. This blocks the calling thread until the thread whose join() method is called terminates – either normally or through an unhandled exception – or until the optional timeout occurs.
This means that the main thread which spawns t
and d
, waits for t
to finish until it finishes.
Depending on the logic your program employs, you may want to wait until a thread finishes before your main thread continues.
Also from the docs:
A thread can be flagged as a “daemon thread”. The significance of this flag is that the entire Python program exits when only daemon threads are left.
A simple example, say we have this:
def non_daemon():
time.sleep(5)
print 'Test non-daemon'
t = threading.Thread(name='non-daemon', target=non_daemon)
t.start()
Which finishes with:
print 'Test one'
t.join()
print 'Test two'
This will output:
Test one
Test non-daemon
Test two
Here the master thread explicitly waits for the t
thread to finish until it calls print
the second time.
Alternatively if we had this:
print 'Test one'
print 'Test two'
t.join()
We'll get this output:
Test one
Test two
Test non-daemon
Here we do our job in the main thread and then we wait for the t
thread to finish. In this case we might even remove the explicit joining t.join()
and the program will implicitly wait for t
to finish.
You wont be able to get python to tell you where the JSON is incorrect. You will need to use a linter online somewhere like this
This will show you error in the JSON you are trying to decode.
Use urllib2 and create a Request object which you then hand to urlopen. http://docs.python.org/library/urllib2.html
I dont really use the "old" urllib anymore.
req = urllib2.Request("http://google.com", None, {'User-agent' : 'Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5'})
response = urllib2.urlopen(req).read()
untested....
You could do this:
int count = test.Split('&').Length - 1;
Or with LINQ:
test.Count(x => x == '&');
Notice the cool thing in S.Lott's comment - you can also call functions with *mylist
and **mydict
to unpack positional and keyword arguments:
def foo(a, b, c, d):
print a, b, c, d
l = [0, 1]
d = {"d":3, "c":2}
foo(*l, **d)
Will print: 0 1 2 3
Try this:
table {
border-spacing: 0;
border-collapse: collapse;
}
Actually, map
and list comprehensions behave quite differently in the Python 3 language. Take a look at the following Python 3 program:
def square(x):
return x*x
squares = map(square, [1, 2, 3])
print(list(squares))
print(list(squares))
You might expect it to print the line "[1, 4, 9]" twice, but instead it prints "[1, 4, 9]" followed by "[]". The first time you look at squares
it seems to behave as a sequence of three elements, but the second time as an empty one.
In the Python 2 language map
returns a plain old list, just like list comprehensions do in both languages. The crux is that the return value of map
in Python 3 (and imap
in Python 2) is not a list - it's an iterator!
The elements are consumed when you iterate over an iterator unlike when you iterate over a list. This is why squares
looks empty in the last print(list(squares))
line.
To summarize:
This is not specific to sqlite but you can just do
SELECT * FROM ... WHERE UPPER(name) = UPPER('someone')
The single-step answer to the first question is to use something like:
update TBL set CLM = CLM + 1 where key = 'KEY'
That's very much a single-instruction way of doing it.
As for the second question, you shouldn't need to resort to DBMS-specific SQL gymnastics (like UPSERT
) to get the result you want. There's a standard method to do update-or-insert that doesn't require a specific DBMS.
try:
insert into TBL (key,val) values ('xyz',0)
catch:
do nothing
update TBL set val = val + 1 where key = 'xyz'
That is, you try to do the creation first. If it's already there, ignore the error. Otherwise you create it with a 0 value.
Then do the update which will work correctly whether or not:
It's not a single instruction and yet, surprisingly enough, it's how we've been doing it successfully for a long long time.
'OR 1=1
is an attempt to make a query succeed no matter what
The /*
is an attempt to start a multiline comment so the rest of the query is ignored.
An example would be
SELECT userid
FROM users
WHERE username = ''OR 1=1/*'
AND password = ''
AND domain = ''
As you can see if you were to populate the username field without escaping the '
no matter what credentials the user passes in the query would return all userids in the system likely granting access to the attacker (possibly admin access if admin is your first user). You will also notice the remainder of the query would be commented out because of the /*
including the real '
.
The fact that you can see the value in your database means that it was escaped and that particular attack did not succeed. However, you should investigate if any other attempts were made.
Beware of properties inherited from the object's prototype (which could happen if you're including any libraries on your page, such as older versions of Prototype). You can check for this by using the object's hasOwnProperty()
method. This is generally a good idea when using for...in
loops:
var user = {};
function setUsers(data) {
for (var k in data) {
if (data.hasOwnProperty(k)) {
user[k] = data[k];
}
}
}
Generate a Windows command file (batch) for installing extensions:

There's a surprisingly nice library for Android HTTP available at the link below:
http://loopj.com/android-async-http/
Simple requests are very easy:
AsyncHttpClient client = new AsyncHttpClient();
client.get("http://www.google.com", new AsyncHttpResponseHandler() {
@Override
public void onSuccess(String response) {
System.out.println(response);
}
});
To send JSON (credit to `voidberg' at https://github.com/loopj/android-async-http/issues/125):
// params is a JSONObject
StringEntity se = null;
try {
se = new StringEntity(params.toString());
} catch (UnsupportedEncodingException e) {
// handle exceptions properly!
}
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
client.post(null, "www.example.com/objects", se, "application/json", responseHandler);
It's all asynchronous, works well with Android and safe to call from your UI thread. The responseHandler will run on the same thread you created it from (typically, your UI thread). It even has a built-in resonseHandler for JSON, but I prefer to use google gson.
Yes, case insensitivity can be enabled and disabled at will in Java regex.
It looks like you want something like this:
System.out.println(
"Have a meRry MErrY Christmas ho Ho hO"
.replaceAll("(?i)\\b(\\w+)(\\s+\\1)+\\b", "$1")
);
// Have a meRry Christmas ho
Note that the embedded Pattern.CASE_INSENSITIVE
flag is (?i)
not \?i
. Note also that one superfluous \b
has been removed from the pattern.
The (?i)
is placed at the beginning of the pattern to enable case-insensitivity. In this particular case, it is not overridden later in the pattern, so in effect the whole pattern is case-insensitive.
It is worth noting that in fact you can limit case-insensitivity to only parts of the whole pattern. Thus, the question of where to put it really depends on the specification (although for this particular problem it doesn't matter since \w
is case-insensitive.
To demonstrate, here's a similar example of collapsing runs of letters like "AaAaaA"
to just "A"
.
System.out.println(
"AaAaaA eeEeeE IiiIi OoooOo uuUuUuu"
.replaceAll("(?i)\\b([A-Z])\\1+\\b", "$1")
); // A e I O u
Now suppose that we specify that the run should only be collapsed only if it starts with an uppercase letter. Then we must put the (?i)
in the appropriate place:
System.out.println(
"AaAaaA eeEeeE IiiIi OoooOo uuUuUuu"
.replaceAll("\\b([A-Z])(?i)\\1+\\b", "$1")
); // A eeEeeE I O uuUuUuu
More generally, you can enable and disable any flag within the pattern as you wish.
java.util.regex.Pattern
/regex/i
(Pattern.CASE_INSENSITIVE
in Java), you can do /(?i)regex/
/first(?i)second(?-i)third/
/first(?i:second)third/
\b
between a \w
and a \s

By the Way Invoke-WebRequest
also prints you the 200 OK
and a lot of bla, bla, bla... which might be useful but I still prefer the Invoke-RestMethod
which is lighter.
Also, keep in mind that you need to use | ConvertTo-Json
for the body only, not the header:
$body = @{
"UserSessionId"="12345678"
"OptionalEmail"="[email protected]"
} | ConvertTo-Json
$header = @{
"Accept"="application/json"
"connectapitoken"="97fe6ab5b1a640909551e36a071ce9ed"
"Content-Type"="application/json"
}
Invoke-RestMethod -Uri "http://MyServer/WSVistaWebClient/RESTService.svc/member/search" -Method 'Post' -Body $body -Headers $header | ConvertTo-HTML
and you can then append a | ConvertTo-HTML
at the end of the request for better readability
oltp- mostly used for business transaction.used to collect business data.In sql we use insert,update and delete command for retrieving small source of data.like wise they are highly normalised.... OLTP Mostly used for maintaining the data integrity.
olap- mostly use for reporting,data mining and business analytic purpose. for the large or bulk data.deliberately it is de-normalised. it stores Historical data..
A simple way to solve this problem is export thePYTHONPATH
variable enviroment. For example, for Python 2.6 in Debian/GNU Linux:
export PYTHONPATH=/usr/lib/python2.6`
In other operating systems, you would first find the location of this module or the socket.py
file.
