Ignoring the refactoring issues, you need to understand functions and return values. You don't need a global at all. Ever. You can do this:
def rps():
# Code to determine if player wins
if player_wins:
return True
return False
Then, just assign a value to the variable outside this function like so:
player_wins = rps()
It will be assigned the return value (either True or False) of the function you just called.
After the comments, I decided to add that idiomatically, this would be better expressed thus:
def rps():
# Code to determine if player wins, assigning a boolean value (True or False)
# to the variable player_wins.
return player_wins
pw = rps()
This assigns the boolean value of player_wins
(inside the function) to the pw
variable outside the function.
This is quick-and-dirty (and not formally valid HTML5), but it seems to work -- and it is inline as per the question:
<table border='1' style='border-collapse:collapse'>
No further styling of <tr>

x86 refers to the Intel processor architecture that was used in PCs. Model numbers were 8088 (8 bit bus version of 8086 and used in the first IBM PC), 8086, 286, 386, 486. After which they switched to names instead of numbers to stop AMD from copying the processor names. Pentium etc, never a Hexium :).
x64 is the architecture name for the extensions to the x86 instruction set that enable 64-bit code. Invented by AMD and later copied by Intel when they couldn't get their own 64-bit arch to be competitive, Itanium didn't fare well. Other names for it are x86_64, AMD's original name and commonly used in open source tools. And amd64, AMD's next name and commonly used in Microsoft tools. Intel's own names for it (EM64T and "Intel 64") never caught on.
x32 is a fuzzy term that's not associated with hardware. It tends to be used to mean "32-bit" or "32-bit pointer architecture", Linux has an ABI by that name.

Basically it compares your Variable's ID to globals() Variables' IDs, then returns the match's name.
def getVariableName(variable, globalVariables=globals().copy()):
""" Get Variable Name as String by comparing its ID to globals() Variables' IDs

for globalVariable in globalVariables:
if id(variable) == id(globalVariables[globalVariable]): # If our Variable's ID matches this Global Variable's ID...
return globalVariable # Return its name from the Globals() dict

Reason why you cannot use function pointers to call member functions is that ordinary function pointers are usually just the memory address of the function.
To call a member function, you need to know two things:
Ordinary function pointers cannot store both. C++ member function pointers are used to store a), which is why you need to specify the instance explicitly when calling a member function pointer.
Use isinstance
:
if isinstance(e, list):
If you want to check that an object is a list or a tuple, pass several classes to isinstance
:
if isinstance(e, (list, tuple)):
I've seen this error while trying to access a column value after processing the resultset.

With Python older than 2.7/3.1, that's pretty much how you do it.
For newer versions, see importlib.import_module
for Python 2 and and Python 3.
You can use exec
if you want to as well.
Or using __import__
you can import a list of modules by doing this:
>>> moduleNames = ['sys', 'os', 're', 'unittest']
>>> moduleNames
['sys', 'os', 're', 'unittest']
>>> modules = map(__import__, moduleNames)
Ripped straight from Dive Into Python.
First you can use a Paginator. This is as simple as:
$allUsers = User::paginate(15);
$someUsers = User::where('votes', '>', 100)->paginate(15);
The variables will contain an instance of Paginator class. all of your data will be stored under data
key.
Or you can do something like:
Old versions Laravel.
Model::all()->take(10)->get();
Newer version Laravel.
Model::all()->take(10);

Javacript uses short-circuit evaluation for logical operators ||
and &&
. However, it's different to other languages in that it returns the result of the last value that halted the execution, instead of a true
, or false
value.
The following values are considered falsy in JavaScript.
""
(empty string)Ignoring the operator precedence rules, and keeping things simple, the following examples show which value halted the evaluation, and gets returned as a result.
false || null || "" || 0 || NaN || "Hello" || undefined // "Hello"
The first 5 values upto NaN
are falsy so they are all evaluated from left to right, until it meets the first truthy value - "Hello"
which makes the entire expression true, so anything further up will not be evaluated, and "Hello"
gets returned as a result of the expression. Similarly, in this case:
1 && [] && {} && true && "World" && null && 2010 // null
The first 5 values are all truthy and get evaluated until it meets the first falsy value (null
) which makes the expression false, so 2010
isn't evaluated anymore, and null
gets returned as a result of the expression.
The example you've given is making use of this property of JavaScript to perform an assignment. It can be used anywhere where you need to get the first truthy or falsy value among a set of values. This code below will assign the value "Hello"
to b
as it makes it easier to assign a default value, instead of doing if-else checks.
var a = false;
var b = a || "Hello";
You could call the below example an exploitation of this feature, and I believe it makes code harder to read.
var messages = 0;
var newMessagesText = "You have " + messages + " messages.";
var noNewMessagesText = "Sorry, you have no new messages.";
alert((messages && newMessagesText) || noNewMessagesText);
Inside the alert, we check if messages
is falsy, and if yes, then evaluate and return noNewMessagesText
, otherwise evaluate and return newMessagesText
. Since it's falsy in this example, we halt at noNewMessagesText and alert "Sorry, you have no new messages."

While both references and pointers are used to indirectly access another value, there are two important differences between references and pointers. The first is that a reference always refers to an object: It is an error to define a reference without initializing it. The behavior of assignment is the second important difference: Assigning to a reference changes the object to which the reference is bound; it does not rebind the reference to another object. Once initialized, a reference always refers to the same underlying object.
Consider these two program fragments. In the first, we assign one pointer to another:
int ival = 1024, ival2 = 2048;
int *pi = &ival, *pi2 = &ival2;
pi = pi2; // pi now points to ival2
After the assignment, ival, the object addressed by pi remains unchanged. The assignment changes the value of pi, making it point to a different object. Now consider a similar program that assigns two references:
int &ri = ival, &ri2 = ival2;
ri = ri2; // assigns ival2 to ival
This assignment changes ival, the value referenced by ri, and not the reference itself. After the assignment, the two references still refer to their original objects, and the value of those objects is now the same as well.
Find out the web server user
open up terminal and type
lsof -i tcp:80
This will show you the user of the web server process Here is an example from a raspberry pi running debian:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
apache2 7478 www-data 3u IPv4 450666 0t0 TCP *:http (LISTEN)
apache2 7664 www-data 3u IPv4 450666 0t0 TCP *:http (LISTEN)
apache2 7794 www-data 3u IPv4 450666 0t0 TCP *:http (LISTEN)
The user is www-data
If you give ownership of the web files to the web server:
chown www-data:www-data -R /opt/lamp/htdocs
And chmod 755 for good measure:
chmod 755 -R /opt/lamp/htdocs
Let me know how you go, maybe you need to use 'sudo' before the command, i.e.
sudo chown www-data:www-data -R /opt/lamp/htdocs
if it doesn't work, please give us the output of:
ls -al /opt/lamp/htdocs
This happens because your upstream takes too much to answer the request and NGINX thinks the upstream already failed in processing the request, so it responds with an error.
Just include and increase proxy_read_timeout in location
config block.
Same thing happened to me and I used 1 hour timeout for an internal app at work:
proxy_read_timeout 3600;
With this, NGINX will wait for an hour (3600s) for its upstream to return something.
It's actually:
Console.WriteLine(Encoding.Default.GetString(value));

Console.WriteLine(Encoding.UTF8.GetString(value));
I'll try to provide a comprehensive answer here. Much of the points appear in other answers, but I found each answer incomplete, and some incorrect.
First and foremost, objectForKey:
is an NSDictionary
method, while valueForKey:
is a KVC protocol method required of any KVC complaint class - including NSDictionary.
Furthermore, as @dreamlax wrote, documentation hints that NSDictionary
implements its valueForKey:
method USING its objectForKey:
implementation. In other words - [NSDictionary valueForKey:]
calls on [NSDictionary objectForKey:]
.
This implies, that valueForKey:
can never be faster than objectForKey:
(on the same input key) although thorough testing I've done imply about 5% to 15% difference, over billions of random access to a huge NSDictionary. In normal situations - the difference is negligible.
Next: KVC protocol only works with NSString *
keys, hence valueForKey:
will only accept an NSString *
(or subclass) as key, whilst NSDictionary
can work with other kinds of objects as keys - so that the "lower level" objectForKey:
accepts any copy-able (NSCopying protocol compliant) object as key.
Last, NSDictionary's
implementation of valueForKey:
deviates from the standard behavior defined in KVC's documentation, and will NOT emit a NSUnknownKeyException
for a key it can't find - unless this is a "special" key - one that begins with '@' - which usually means an "aggregation" function key (e.g. @"@sum, @"@avg"
). Instead, it will simply return a nil when a key is not found in the NSDictionary - behaving the same as objectForKey:
Following is some test code to demonstrate and prove my notes.
- (void) dictionaryAccess {
NSLog(@"Value for Z:%@", [@{@"X":@(10), @"Y":@(20)} valueForKey:@"Z"]); // prints "Value for Z:(null)"
uint32_t testItemsCount = 1000000;
// create huge dictionary of numbers
NSMutableDictionary *d = [NSMutableDictionary dictionaryWithCapacity:testItemsCount];
for (long i=0; i<testItemsCount; ++i) {
// make new random key value pair:
NSString *key = [NSString stringWithFormat:@"K_%u",arc4random_uniform(testItemsCount)];
NSNumber *value = @(arc4random_uniform(testItemsCount));
[d setObject:value forKey:key];
}
// create huge set of random keys for testing.
NSMutableArray *keys = [NSMutableArray arrayWithCapacity:testItemsCount];
for (long i=0; i<testItemsCount; ++i) {
NSString *key = [NSString stringWithFormat:@"K_%u",arc4random_uniform(testItemsCount)];
[keys addObject:key];
}
NSDictionary *dict = [d copy];
NSTimeInterval vtotal = 0.0, ototal = 0.0;
NSDate *start;
NSTimeInterval elapsed;
for (int i = 0; i<10; i++) {
start = [NSDate date];
for (NSString *key in keys) {
id value = [dict valueForKey:key];
}
elapsed = [[NSDate date] timeIntervalSinceDate:start];
vtotal+=elapsed;
NSLog (@"reading %lu values off dictionary via valueForKey took: %10.4f seconds", keys.count, elapsed);
start = [NSDate date];
for (NSString *key in keys) {
id obj = [dict objectForKey:key];
}
elapsed = [[NSDate date] timeIntervalSinceDate:start];
ototal+=elapsed;
NSLog (@"reading %lu objects off dictionary via objectForKey took: %10.4f seconds", keys.count, elapsed);
}
NSString *slower = (vtotal > ototal) ? @"valueForKey" : @"objectForKey";
NSString *faster = (vtotal > ototal) ? @"objectForKey" : @"valueForKey";
NSLog (@"%@ takes %3.1f percent longer then %@", slower, 100.0 * ABS(vtotal-ototal) / MAX(ototal,vtotal), faster);
}

<-ansi
is an obsolete switch that requests the compiler to compile according to the 30-year-old obsolete revision of C standard, ISO/IEC 9899:1990, which is essentially a rebranding of the ANSI standard X3.159-1989 "Programming Language C. Why obsolete? Because after C90 was published by ISO, ISO has been in charge of the C standardization, and any technical corrigenda to C90 have been standardized by ISO. Thus it is more apt to use the -std=c90
.
Without this switch, the recent GCC C compilers will conform to the C language standardized in ISO/IEC 9899:2011, or the newest 2018 revision.
Unfortunately there are some lazy compiler vendors that believe it is acceptable to stick to an older obsolete standard revision, for which the standardization document is not even available from standard bodies.
Using the switch helps ensuring that the code should compile in these obsolete compilers.
The -pedantic
is an interesting one. In absence of -pedantic
, even when a specific standard is requested, GCC will still allow some extensions that are not acceptable in the C standard. Consider for example the program
struct test {
int zero_size_array[0];
};
The C11 draft n1570 paragraph 6.7.6.2p1 says:
In addition to optional type qualifiers and the keyword static, the [ and ] may delimit an expression or *. If they delimit an expression (which specifies the size of an array), the expression shall have an integer type. If the expression is a constant expression, it shall have a value greater than zero.[...]
The C standard requires that the array length be greater than zero; and this paragraph is in the constraints; the standard says the following 5.1.1.3p1:
A conforming implementation shall produce at least one diagnostic message (identified in an implementation-defined manner) if a preprocessing translation unit or translation unit contains a violation of any syntax rule or constraint, even if the behavior is also explicitly specified as undefined or implementation-defined. Diagnostic messages need not be produced in other circumstances.9)
However, if you compile the program with gcc -c -std=c90 pedantic_test.c
, no warning is produced.
-pedantic
causes the compiler to actually comply to the C standard; so now it will produce a diagnostic message, as is required by the standard:
gcc -c -pedantic -std=c90 pedantic_test.c
pedantic_test.c:2:9: warning: ISO C forbids zero-size array ‘zero_size_array’ [-Wpedantic]
int zero_size_array[0];
^~~~~~~~~~~~~~~
Thus for maximal portability, specifying the standard revision is not enough, you must also use -pedantic
(or -pedantic-errors
) to ensure that GCC actually does comply to the letter of the standard.
The last part of the question was about using -ansi
with C++. ANSI never standardized the C++ language - only adopting it from ISO, so this makes about as much sense as saying "English as standardized by France". However GCC still seems to accept it for C++, as stupid as it sounds.
First, you have to run below codes in Anaconda prompt
,
conda create -n py27 python=2.7 #for version 2.7
activate py27
conda create -n py36 python=3.6 #for version 3.6
activate py36
Then, you have to open Anaconda navigator
and,
The button might say "install" instead of Launch. After the installation, which takes a few moments, It will be ready to launch.

I've experienced the same problem. The thing is that I forgot to start the apache and mysql in xampp... :S
As for me, these are just different methods. The first one leaves the object you're iterating on unchanged, while the seconds leaves it empty. The question is what do you want to do. The complexity of removing is based on implementation of your iterable object. If you're using Collections - just obtain the size like was proposed by Kazekage Gaara - its usually the best approach performance wise.

As Victoria wrote, Google Maps is no longer free, but you can switch your map provider. You may be interested in OpenStreetMap, there is an easy way to use it on your site described here: https://handyman.dulare.com/switching-from-google-maps-to-openstreetmap/
Unfortunately, on the OpenStreetMap, there is no easy way to provide directions from one point to another, there is also no street view.
The simplest way would be to use FOpen or one of FOpen's Wrappers.
$page = file_get_contents("http://www.domain.com/filename");
This does require FOpen which some web hosts disable and some web hosts will allow FOpen, but not allow access to external files. You may want to check where you are going to run the script to see if you have access to External FOpen.

Very annoying, no cookie file exmpale on the official website https://ec.haxx.se/http/http-cookies.
Finnaly, I find it does not work, if your file content is just copyied like this
foo1=bar;foo2=bar2
I gusess the format must looks the style said by @Agustí Sánchez . You can test it by -c to create a cookie file on a website.
So try this way, it works
curl -H "Cookie:`cat ./my.cookie`" http://xxxx.com
You can just copy the cookie from chrome console network tab.

foreach (T item in data)
{
for (int i = 0; i < values.Length; i++)

I know this is old, but here is a additional thing if you still encounter problems with the solution above.
Just put in your <head>
:
<meta http-equiv="X-UA-Compatible" content="IE=edge">
It will prevent IE to jump back to IE9 compatibility, thus breaking the video function. Worked for me, so if you still have problems, consider checking this out.
Alternatively you can add this in PHP :
header('x-ua-compatible: ie=edge');
Or in a .htaccess file:
header set X-UA-Compatible "IE=Edge"
Rather than using a DisplayFilter you could use a very simple CaptureFilter like
port 53
See the "Capture only DNS (port 53) traffic" example on the CaptureFilters wiki.
I would prefer not use Count function at all:
IF [NOT] EXISTS ( SELECT 1 FROM MyTable WHERE ... )
<do smth>
For example if you want to check if user exists before inserting it into the database the query can look like this:
IF NOT EXISTS ( SELECT 1 FROM Users WHERE FirstName = 'John' AND LastName = 'Smith' )
BEGIN
INSERT INTO Users (FirstName, LastName) VALUES ('John', 'Smith')
END
For variables describing distances, you would use \newlength
(and manipulate the values with \setlength
, \addlength
, \settoheight
, \settolength
and \settodepth
).
Similarly you have access to \newcounter
for things like section and figure numbers which should increment throughout the document. I've used this one in the past to provide code samples that were numbered separatly of other figures...
Also of note is \makebox
which allows you to store a bit of laid-out document for later re-use (and for use with \settolength
...).
Adding the - will order it in descending order. You can also set this by adding a default ordering to the meta of your model. This will mean that when you do a query you just do MyModel.objects.all() and it will come out in the correct order.
class MyModel(models.Model):
check_in = models.DateField()
class Meta:
ordering = ('-check_in',)
Well, you could erase()
the first character too (note that erase()
modifies the string):
m_VirtualHostName.erase(0, 1);
m_VirtualHostName.erase(m_VirtualHostName.size() - 1);
But in this case, a simpler way is to take a substring:
m_VirtualHostName = m_VirtualHostName.substr(1, m_VirtualHostName.size() - 2);
Be careful to validate that the string actually has at least two characters in it first...
The following will allow you to get at both the key and value at the same time.
foreach ($arr as $key => $value)
{
echo($key);
}
I added the vendor prefixes, and changed the animation to all

amp = 2*np.sqrt(2)
freq = 1234.0
noise_power = 0.001 * fs / 2

x = amp*np.sin(2*np.pi*freq*time)
x += np.random.normal(scale=np.sqrt(noise_power), size=time.shape)
# np.fft.fft
freqs = np.fft.fftfreq(time.size, 1/fs)
idx = np.argsort(freqs)
ps = np.abs(np.fft.fft(x))**2
plt.figure()
plt.plot(freqs[idx], ps[idx])

Query all users and filter by the list from your text file:
$Users = Get-Content 'C:\scripts\Users.txt'
Get-ADUser -Filter '*' -Properties DisplayName,Office |
Where-Object { $Users -contains $_.SamAccountName } |
Select-Object DisplayName, Office |
Export-Csv 'C:\path\to\your.csv' -NoType
Get-ADUser -Filter '*'
returns all AD user accounts. This stream of user objects is then piped into a Where-Object
filter, which checks for each object if its SamAccountName
property is contained in the user list from your input file ($Users
). Only objects with a matching account name are passed forward to the next step of the pipeline. The output can be limited by selecting the relevant properties before exporting the data.
You can further optimize the code by replacing the -contains
operator with hashtable lookups:
$Users = @{}
Get-Content 'C:\scripts\Users.txt' | ForEach-Object { $Users[$_] = $true }
Get-ADUser -Filter '*' -Properties DisplayName,Office |
Where-Object { $Users.ContainsKey($_.SamAccountName) } |
Select-Object DisplayName, Office |
Export-Csv 'C:\path\to\your.csv' -NoType
Note that git checkout --ours|--theirs
will overwrite the files entirely, by choosing either theirs

version, which might be or might not be what you want to do (if you have any non-conflicted changes coming from the other side, they will be lost).
If instead you want to perform a three-way merge on the file, and only resolve the conflicted hunks using --ours|--theirs
, while keeping non-conflicted hunks from both sides in place, you may want to resort to git merge-file
; see details in this answer.
In my case, I've created a wrapper JS file in which I have the logic to select the correct variables according to my environment, dynamically.
I have these two functions, one it's a wrapper of a simple dotenv functionality, and the other discriminate between environments and set the result to the process.env object.
setEnvVariablesByEnvironment : ()=>{_x000D_
return new Promise((resolve)=>{_x000D_
_x000D_
if (process.env.NODE_ENV === undefined || process.env.NODE_ENV ==='development'){_x000D_
logger.info('Lower / Development environment was detected');_x000D_
_x000D_
environmentManager.getEnvironmentFromEnvFile()_x000D_

So, in my server.js file i only added the reference:
const envManager = require('./lib/application/config/environment/environment-manager');
And in my entry-point (server.js), it's just simple as use it.
envManager.setEnvVariablesByEnvironment()
.then(envVariables=>{
process.env= envVariables.payload;
const port = process.env.PORT_EXPOSE;
microService.listen(port, '0.0.0.0' , () =>{
let welcomeMessage = `Micro Service started at ${Date.now()}`;
logger.info(welcomeMessage);
logger.info(`${configuration.about.name} port configured -> : ${port}`);
logger.info(`App Author: ${configuration.about.owner}`);
logger.info(`App Version: ${configuration.about.version}`);
logger.info(`Created by: ${configuration.about.author}`);
});
});
Use this:
client.user.setActivity("with depression", {
type: "STREAMING",
url: "https://www.twitch.tv/monstercat"
});
You're a little confused about how objects work in JavaScript. The object's reference is the value of the variable. There is no unserialized value. When you create an object, its structure is stored in memory and the variable it was assigned to holds a reference to that structure.
Even if what you're asking was provided in some sort of easy, native language construct it would still technically be cloning.
JavaScript is really just pass-by-value... it's just that the value passed might be a reference to something.
No, image/jpg
is not the same as image/jpeg
.
You should use image/jpeg
. Only image/jpeg
is recognised as the actual mime type for JPEG files.
See https://tools.ietf.org/html/rfc3745, https://www.w3.org/Graphics/JPEG/ .
Serving the incorrect Content-Type of image/jpg
to IE can cause issues, see http://www.bennadel.com/blog/2609-internet-explorer-aborts-images-with-the-wrong-mime-type.htm.
Use the following simple way to interactively get user data by a prompt as Arguments on what you want.
Version : Python 3.X
name = input('Enter Your Name: ')
print('Hello ', name)
Use the modern version of the Fisher–Yates shuffle algorithm:
/**
* Shuffles array in place.
* @param {Array} a items An array containing the items.
*/
function shuffle(a) {
var j, x, i;
for (i = a.length - 1; i > 0; i--) {
j = Math.floor(Math.random() * (i + 1));
x = a[i];
a[i] = a[j];
a[j] = x;
}
return a;
}
/**
* Shuffles array in place. ES6 version
* @param {Array} a items An array containing the items.
*/
function shuffle(a) {
for (let i = a.length - 1; i > 0; i--) {
const j = Math.floor(Math.random() * (i + 1));
[a[i], a[j]] = [a[j], a[i]];
}
return a;
}
Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.
var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);
Using Object.defineProperty
(method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr)
. The following will allow you to call arr.shuffle()
to shuffle the array arr
:
Object.defineProperty(Array.prototype, 'shuffle', {
value: function() {
for (let i = this.length - 1; i > 0; i--) {
const j = Math.floor(Math.random() * (i + 1));
[this[i], this[j]] = [this[j], this[i]];
}
return this;
}
});
On Windows 10, with Python 3.6.X version I was facing same then after checking deliberately , I noticed I had Python-32 bit installation on my 64 bit machine. Remember TensorFlow is only compatible with 64bit installation of python. Not 32 bit of Python
If we download Python from python.org , the default installation would be 32 bit. So we have to download 64 bit installer manually to install Python 64 bit. And then add
Then run gpupdate /Force
on command prompt. If python command doesnt work for 64 bit restart your machine.
Then run python on command prompt. It should show 64 bit
C:\Users\YOURNAME>python
Python 3.6.3 (v3.6.3:2c5fed8, Oct 3 2017, 18:11:49) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
Then run below command to install tensorflow CPU version(recommended)
pip3 install --upgrade tensorflow
I met this problem on my project too.
This helped me, so hopefuly will help someone else:
adb uninstall "com.domain.yourapp"
The solutions posted so far are needlessly complicated, in my opinion. There's a simpler way. The documentation of ui-router
says listen to $locationChangeSuccess
and use $urlRouter.sync()
to check a state transition, halt it, or resume it. But even that actually doesn't work.
However, here are two simple alternatives. Pick one:
$locationChangeSuccess
You can listen to $locationChangeSuccess
and you can perform some logic, even asynchronous logic there. Based on that logic, you can let the function return undefined, which will cause the state transition to continue as normal, or you can do $state.go('logInPage')
, if the user needs to be authenticated. Here's an example:
angular.module('App', ['ui.router'])
// In the run phase of your Angular application
.run(function($rootScope, user, $state) {
// Listen to '$locationChangeSuccess', not '$stateChangeStart'
$rootScope.$on('$locationChangeSuccess', function() {
user
.logIn()
.catch(function() {
// log-in promise failed. Redirect to log-in page.
$state.go('logInPage')
})
})
})
Keep in mind that this doesn't actually prevent the target state from loading, but it does redirect to the log-in page if the user is unauthorized. That's okay since real protection is on the server, anyway.
resolve
In this solution, you use ui-router
resolve feature.
You basically reject the promise in resolve
if the user is not authenticated and then redirect them to the log-in page.
Here's how it goes:
angular.module('App', ['ui.router'])
.config(
function($stateProvider) {
$stateProvider
.state('logInPage', {
url: '/logInPage',
templateUrl: 'sections/logInPage.html',
controller: 'logInPageCtrl',
})
.state('myProtectedContent', {
url: '/myProtectedContent',
templateUrl: 'sections/myProtectedContent.html',
controller: 'myProtectedContentCtrl',
resolve: { authenticate: authenticate }
})
.state('alsoProtectedContent', {
url: '/alsoProtectedContent',
templateUrl: 'sections/alsoProtectedContent.html',
controller: 'alsoProtectedContentCtrl',
resolve: { authenticate: authenticate }
})
function authenticate($q, user, $state, $timeout) {
if (user.isAuthenticated()) {
// Resolve the promise successfully
return $q.when()
} else {
// The next bit of code is asynchronously tricky.
$timeout(function() {
// This code runs after the authentication promise has been rejected.
// Go to the log-in page
$state.go('logInPage')
})
// Reject the authentication promise to prevent the state from loading
return $q.reject()
}
}
}
)
Unlike the first solution, this solution actually prevents the target state from loading.
I know it's late and was answered, but I'd like to share the neat stuff I made. I created an ng-validate directive that hooks the onsubmit of the form, then it issues prevent-default if the $eval is false:
app.directive('ngValidate', function() {
return function(scope, element, attrs) {
if (!element.is('form'))
throw new Error("ng-validate must be set on a form elment!");
element.bind("submit", function(event) {
if (!scope.$eval(attrs.ngValidate, {'$event': event}))
event.preventDefault();
if (!scope.$$phase)
scope.$digest();
});
};
});
In your html:
<form name="offering" method="post" action="offer" ng-validate="<boolean expression">
Arrays are objects and they have a length field.
String[] haha = {"olle", "bulle"};
haha.length would be 2

i think i'd try with MAX something like this:
SELECT staff_id, max( date ) from owner.table group by staff_id
then link in your other columns:
select staff_id, site_id, pay_level, latest
from owner.table,
( SELECT staff_id, max( date ) latest from owner.table group by staff_id ) m
where m.staff_id = staff_id

There is a function specifically for this. It is called numpy.pad
a = np.array([[1,2,3], [2,3,4]])
b = np.pad(a, ((0, 0), (0, 1)), mode='constant', constant_values=0)
print b
>>> array([[1, 2, 3, 0],
[2, 3, 4, 0]])
Here is what it says in the docstring:
Pads an array.
Parameters
----------
array : array_like of rank N
Input array
pad_width : {sequence, array_like, int}
Number of values padded to the edges of each axis.
((before_1, after_1), ... (before_N, after_N)) unique pad widths
for each axis.
((before, after),) yields same before and after pad for each axis.
(pad,) or int is a shortcut for before = after = pad width for all
axes.
mode : str or function
One of the following string values or a user supplied function.
'constant'
Pads with a constant value.
'edge'
Pads with the edge values of array.
'linear_ramp'
Pads with the linear ramp between end_value and the
array edge value.
'maximum'
Pads with the maximum value of all or part of the
vector along each axis.
'mean'
Pads with the mean value of all or part of the
vector along each axis.
'median'
Pads with the median value of all or part of the
vector along each axis.
'minimum'
Pads with the minimum value of all or part of the
vector along each axis.
'reflect'
Pads with the reflection of the vector mirrored on
the first and last values of the vector along each
axis.
'symmetric'
Pads with the reflection of the vector mirrored
along the edge of the array.
'wrap'
Pads with the wrap of the vector along the axis.
The first values are used to pad the end and the
end values are used to pad the beginning.
<function>
Padding function, see Notes.
stat_length : sequence or int, optional
Used in 'maximum', 'mean', 'median', and 'minimum'. Number of
values at edge of each axis used to calculate the statistic value.
((before_1, after_1), ... (before_N, after_N)) unique statistic
lengths for each axis.
((before, after),) yields same before and after statistic lengths
for each axis.
(stat_length,) or int is a shortcut for before = after = statistic
length for all axes.
Default is ``None``, to use the entire axis.
constant_values : sequence or int, optional
Used in 'constant'. The values to set the padded values for each
axis.
((before_1, after_1), ... (before_N, after_N)) unique pad constants
for each axis.
((before, after),) yields same before and after constants for each
axis.
(constant,) or int is a shortcut for before = after = constant for
all axes.
Default is 0.
end_values : sequence or int, optional
Used in 'linear_ramp'. The values used for the ending value of the
linear_ramp and that will form the edge of the padded array.
((before_1, after_1), ... (before_N, after_N)) unique end values
for each axis.
((before, after),) yields same before and after end values for each
axis.
(constant,) or int is a shortcut for before = after = end value for
all axes.
Default is 0.
reflect_type : {'even', 'odd'}, optional
Used in 'reflect', and 'symmetric'. The 'even' style is the
default with an unaltered reflection around the edge value. For
the 'odd' style, the extented part of the array is created by
subtracting the reflected values from two times the edge value.
Returns
-------
pad : ndarray
Padded array of rank equal to `array` with shape increased
according to `pad_width`.
Notes
-----
.. versionadded:: 1.7.0
For an array with rank greater than 1, some of the padding of later
axes is calculated from padding of previous axes. This is easiest to
think about with a rank 2 array where the corners of the padded array
are calculated by using padded values from the first axis.
The padding function, if used, should return a rank 1 array equal in
length to the vector argument with padded values replaced. It has the
following signature::
padding_func(vector, iaxis_pad_width, iaxis, kwargs)
where
vector : ndarray
A rank 1 array already padded with zeros. Padded values are
vector[:pad_tuple[0]] and vector[-pad_tuple[1]:].
iaxis_pad_width : tuple
A 2-tuple of ints, iaxis_pad_width[0] represents the number of
values padded at the beginning of vector where
iaxis_pad_width[1] represents the number of values padded at
the end of vector.
iaxis : int
The axis currently being calculated.
kwargs : dict
Any keyword arguments the function requires.

var header = []
var rows = []
var firstRow = true
cursor.forEach((doc) =>
{
var cells = []
if (firstRow) header.push("employee_number")
cells.push(doc.EmpNum.valueOf())
if (firstRow) header.push("name")
cells.push(doc.FullName.valueOf())
if (firstRow) header.push("dob")

As mentioned there are many services out there, if you are looking to truly validate the entire address then I highly recommend going with a Web Service type service to ensure that changes can quickly be recognized by your application.
In addition to the services listed above, webservice.net has this US Address Validation service. http://www.webservicex.net/WCF/ServiceDetails.aspx?SID=24
The answers mentioned here is quite elegant https://stackoverflow.com/a/6095776/1869562 but upon testing, I realize it only returns the last name. What if you want to return the entire record itself ? Do this (For Mysql)
SELECT *
FROM `beneficiary`
WHERE `lastname`
IN (
SELECT `lastname`
FROM `beneficiary`
GROUP BY `lastname`
HAVING COUNT( `lastname` ) >1
)
I had a similar issue; the problem was that the .gitconfig
file was located in
C:\Users\MyLogin\.gitconfig\
(on Windows 7)
In other words, the file was located in C:\Users\MyLogin\.gitconfig\.gitconfig
, instead of on C:\Users\MyLogin\.gitconfig
(which is where Git was looking for the files).
In lollipop and up:
Add to mainfest:
<uses-permission android:name="android.permission.GET_TASKS" />
And do something like this:

{
List<AppTask> tasks = mActivityManager.getAppTasks();
if( tasks.size() > 0 )
mTaskId = tasks.get( 0 ).getTaskInfo().id;
}
I have the same problem and found that this is the problem of Microsoft vulnerabilities.
It works for me when I install these update patches. You can find these patches on www.microsoft.com .
If your office 2010 version is SP1, you need download and install office SP2 pack first. Update patch name is KB2687455.
Install update patch KB2965240.
This security update resolves vulnerabilities in Microsoft Office that could allow remote code execution if an attacker convinces a user to open or preview a specially crafted Microsoft Excel workbook in an affected version of Office. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user.
Install update patch KB2553154.
A security vulnerability exists in Microsoft Office 2010 32-Bit Edition that could allow arbitrary code to run when a maliciously modified file is opened. This update resolves that vulnerability.
One-liner:
$ python -c "import urllib2; print urllib2.build_opener(urllib2.HTTPHandler(debuglevel=1)).open(urllib2.Request('http://google.com'))"
in gradle.properties, you can even delete
org.gradle.jvmargs=-Xmx1536m
such lines or comment them out. Let android studio decide for it. When I ran into this same problem, none of above solutions worked for me. Commenting out this line in gradle.properties helped in solving that error.
In my case I was using the prototype name as the object name. For e.g.
function proto1()
{}
var proto1 = new proto1();
It was a silly mistake but might be of help to someone like me ;)
You could try to assign properties to the ENUM you're trying to create and statically contruct it by using a loaded properties file. Big hack, but it works :)
argc
is the number of command line arguments and argv
is array of strings representing command line arguments.
This gives you the option to react to the arguments passed to the program. If you are expecting none, you might as well use int main
.
Exception.Message
contains only the message (doh) associated with the exception. Example:
Object reference not set to an instance of an object
The Exception.ToString()
method will give a much more verbose output, containing the exception type, the message (from before), a stack trace, and all of these things again for nested/inner exceptions. More precisely, the method returns the following:
ToString returns a representation of the current exception that is intended to be understood by humans. Where the exception contains culture-sensitive data, the string representation returned by ToString is required to take into account the current system culture. Although there are no exact requirements for the format of the returned string, it should attempt to reflect the value of the object as perceived by the user.
The default implementation of ToString obtains the name of the class that threw the current exception, the message, the result of calling ToString on the inner exception, and the result of calling Environment.StackTrace. If any of these members is a null reference (Nothing in Visual Basic), its value is not included in the returned string.
If there is no error message or if it is an empty string (""), then no error message is returned. The name of the inner exception and the stack trace are returned only if they are not a null reference (Nothing in Visual Basic).
@HostListener
is a decorator for the callback/event handler method, so remove the ;
at the end of this line:
@HostListener('click', ['$event.target']);
Here's a working plunker that I generated by copying the code from the API docs, but I put the onClick()
method on the same line for clarity:
import {Component, HostListener, Directive} from 'angular2/core';
@Directive({selector: 'button[counting]'})
class CountClicks {
numberOfClicks = 0;
@HostListener('click', ['$event.target']) onClick(btn) {
console.log("button", btn, "number of clicks:", this.numberOfClicks++);
}
}
@Component({
selector: 'my-app',
template: `<button counting>Increment</button>`,
directives: [CountClicks]
})
export class AppComponent {
constructor() { console.clear(); }
}
Host binding can also be used to listen to global events:
To listen to global events, a target must be added to the event name. The target can be window, document or body (reference)
@HostListener('document:keyup', ['$event'])
handleKeyboardEvent(kbdEvent: KeyboardEvent) { ... }
Truncate
table is preferred because it clears the records, resets the counter and reclaims the disk space.
Delete
and CheckIdent
should be used only where foreign keys prevent you from truncating.
From the id Selector jQuery page:
Each id value must be used only once within a document. If more than one element has been assigned the same ID, queries that use that ID will only select the first matched element in the DOM. This behavior should not be relied on, however; a document with more than one element using the same ID is invalid.
Naughty Google. But they don't even close their <html>
and <body>
tags I hear. The question is though, why Misha's 2nd and 3rd queries return 2 and not 1 as well.
in the latest packages you can also use
vp.getCurrentItem()
or
vp is the viewPager ,
pageListener = new PageListener();
vp.setOnPageChangeListener(pageListener);
you have to put a page change listener for your viewPager. There is no method on viewPager to get the current page.
private int currentPage;
private static class PageListener extends SimpleOnPageChangeListener{
public void onPageSelected(int position) {
Log.i(TAG, "page selected " + position);
currentPage = position;
}
}

New link for the icons image size by apple.
https://developer.apple.com/ios/human-interface-guidelines/graphics/image-size-and-resolution/
Yes it's True here it is Apple provide Official documentation regarding icon's or image size
you have to set images for iPhone6 and iPhone6+
For iPhone 6:
750 x 1334 (@2x) for portrait
1334 x 750 (@2x) for landscape
For iPhone 6 Plus:
1242 x 2208 (@3x) for portrait
2208 x 1242 (@3x) for landscape
For more info regarding Images and it's resolution this is best ever helpful post
For setting images size for controls you can set 1x @2x and @3x like following:
If you want to delete items after some time, e.g. after a month, just use Time To Live option. It will not count write units.
In your case, I would add ttl when logs expire and leave those after a user is deleted. TTL would make sure logs are removed eventually.
When Time To Live is enabled on a table, a background job checks the TTL attribute of items to see if they are expired.
DynamoDB typically deletes expired items within 48 hours of expiration. The exact duration within which an item truly gets deleted after expiration is specific to the nature of the workload and the size of the table. Items that have expired and not been deleted will still show up in reads, queries, and scans. These items can still be updated and successful updates to change or remove the expiration attribute will be honored.

Almost there. In your predicate, you want a relative path, so change
./book[/author/name = 'John']
to either
./book[author/name = 'John']
or
./book[./author/name = 'John']
and you will match your element. Your current predicate goes back to the root of the document to look for an author
.
"Is the order of elements in a JSON list maintained?" is not a good question. You need to ask "Is the order of elements in a JSON list maintained when doing [...] ?" As Felix King pointed out, JSON is a textual data format. It doesn't mutate without a reason. Do not confuse a JSON string with a (JavaScript) object.
You're probably talking about operations like JSON.stringify(JSON.parse(...))
. Now the answer is: It depends on the implementation. 99%* of JSON parsers do not maintain the order of objects, and do maintain the order of arrays, but you might as well use JSON to store something like
{
"son": "David",
"daughter": "Julia",
"son": "Tom",
"daughter": "Clara"
}
and use a parser that maintains order of objects.
*probably even more :)
Ok after some digging I found a solution for "Can't bind to 'formGroup' since it isn't a known property of 'form'."
For my case, I've been using multiple modules files, i added ReactiveFormsModule in app.module.ts
import { FormsModule, ReactiveFormsModule } from '@angular/forms';`
@NgModule({
declarations: [
AppComponent,
]
imports: [
FormsModule,
ReactiveFormsModule,
AuthorModule,
],
...
But this wasn't working when I use a [formGroup] directive from a component added in another module, e.g. using [formGroup] in author.component.ts which is subscribed in author.module.ts file:
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { AuthorComponent } from './author.component';
@NgModule({
imports: [
CommonModule,
],
declarations: [
AuthorComponent,
],
providers: [...]
})
export class AuthorModule {}
I thought if i added ReactiveFormsModule in app.module.ts, by default ReactiveFormsModule would be inherited by all its children modules like author.module in this case... (wrong!). I needed to import ReactiveFormsModule in author.module.ts in order to make all directives to work:
...
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
...
@NgModule({
imports: [
...,
FormsModule, //added here too
ReactiveFormsModule //added here too
],
declarations: [...],
providers: [...]
})
export class AuthorModule {}
So, if you are using submodules, make sure to import ReactiveFormsModule in each submodule file. Hope this helps anyone.
Try reducing the range of the for loop to range(len(a)-1)
:
a = [0,1,2,3]
b = []
for i in range(len(a)-1):
b.append(a[i]+a[i+1])
print(b)
This can also be written as a list comprehension:
b = [a[i] + a[i+1] for i in range(len(a)-1)]
print(b)
if you open localhost/phpmyadmin
you will find a tab called "User accounts". There you can define all your users that can access the mysql database, set their rights and even limit from where they can connect.
If you installed pip like this:
- sudo apt install python-pip
- sudo apt install python3-pip
Uninstall them like this:
- sudo apt remove python-pip

The accepted answer throws a ProtocolException at:
OutputStream os = conn.getOutputStream();
because it does not enable the output for the URLConnection object. The solution should include this:
conn.setDoOutput(true);
to make it work.
You need
ALTER TABLE YourTable ALTER COLUMN YourColumn <<new_datatype>> [NULL | NOT NULL]
But remember to specify NOT NULL
explicitly if desired.
ALTER TABLE YourTable ALTER COLUMN YourColumn VARCHAR (500) NOT NULL;
If you leave it unspecified as below...
ALTER TABLE YourTable ALTER COLUMN YourColumn VARCHAR (500);
Then the column will default to allowing nulls even if it was originally defined as NOT NULL
. i.e. omitting the specification in an ALTER TABLE ... ALTER COLUMN
is always treated as.
ALTER TABLE YourTable ALTER COLUMN YourColumn VARCHAR (500) NULL;
This behaviour is different from that used for new columns created with ALTER TABLE
(or at CREATE TABLE
time). There the default nullability depends on the ANSI_NULL_DFLT
settings.
//arraylist/Pojo you can Pass using bundle like this
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
Bundle args = new Bundle();
args.putSerializable("imageSliders",(Serializable)allStoriesPojo.getImageSliderPojos());
intent.putExtra("BUNDLE",args);
startActivity(intent);
Get SecondActivity like this
Intent intent = getIntent();
Bundle args = intent.getBundleExtra("BUNDLE");
String filter = bundle.getString("imageSliders");
//Happy coding
Whenever you see this error, go to Configuration directory and check for a log file generated just now. It should have proper Exception stacktrace. Mine was a case where I got an updated 32-bit JRE (or JVM) installed which was the default Java that got added to the Path. And my Eclipse installation was 64-bit which meant it needed a 64-bit VM to run its native SWT libraries. So I simply uninstalled the 32-bit JVM and replaced it with a 64-bit JVM.
I wonder if they will improve this reporting mechanism, instead of silently generating a log file in some directory.
There are some good answers for it. I want to explain it through demo per Doc
CMD
defines default commands and/or parameters for a container. CMD is an instruction that is best to use if you need a default command which users can easily override. If a Dockerfile has multiple CMDs, it only applies the instructions from the last one.ENTRYPOINT
is preferred when you want to define a container with a specific executable.You cannot override an ENTRYPOINT
when starting a container unless you add the --entrypoint
flag.

THE PROBLEM is here: onClick={this.handleButtonChange(false)}
When you pass this.handleButtonChange(false)
to onClick, you are actually calling the function with value = false
and setting onClick to the function's return value, which is undefined. Also, calling this.handleButtonChange(false)
then calls this.setState()
which triggers a re-render, resulting in an infinite render loop.
THE SOLUTION is to pass the function in a lambda: onClick={() => this.handleButtonChange(false)}
. Here you are setting onClick to equal a function that will call handleButtonChange(false) when the button is clicked.
The below example may help:
function handleButtonChange(value){
console.log("State updated!")
}
console.log(handleButtonChange(false))
//output: State updated!
//output: undefined
console.log(() => handleButtonChange(false))
//output: ()=>{handleButtonChange(false);}
From the docs:
str.split([sep[, maxsplit]])
Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most
maxsplit+1
elements).
s.split('mango', 1)[1]

There are plenty of wonderful answers here already, but I wanted to throw in 1 more option for those wanting to add a new column to the original dataset that contains the number of times that row is repeated.
df1$counts <- sapply(X = paste(df1$Year, df1$Month),
FUN = function(x) { sum(paste(df1$Year, df1$Month) == x) })
The same could be accomplished by combining any of the above answers with the merge()
function.
I would think that one reason could be that the color is applied to things other than font. For example:
div {
border: 1px solid;
color: red;
}
Yields both a red font color and a red border.
Alternatively, it could just be that the W3C's CSS standards are completely backwards and nonsensical as evidenced elsewhere.
In JavaScript, most functions are both callable and instantiable: they have both a [[Call]] and [[Construct]] internal methods.
As callable objects, you can use parentheses to call them, optionally passing some arguments. As a result of the call, the function can return a value.
var player = makeGamePlayer("John Smith", 15, 3);
The code above calls function makeGamePlayer
and stores the returned value in the variable player
. In this case, you may want to define the function like this:
function makeGamePlayer(name, totalScore, gamesPlayed) {
// Define desired object
var obj = {
name: name,
totalScore: totalScore,
gamesPlayed: gamesPlayed
};
// Return it
return obj;
}
Additionally, when you call a function you are also passing an additional argument under the hood, which determines the value of this
inside the function. In the case above, since makeGamePlayer
is not called as a method, the this
value will be the global object in sloppy mode, or undefined in strict mode.
As constructors, you can use the new
operator to instantiate them. This operator uses the [[Construct]] internal method (only available in constructors), which does something like this:
.prototype
of the constructorthis
valuevar player = new GamePlayer("John Smith", 15, 3);
The code above creates an instance of GamePlayer
and stores the returned value in the variable player
. In this case, you may want to define the function like this:
function GamePlayer(name,totalScore,gamesPlayed) {
// `this` is the instance which is currently being created
this.name = name;
this.totalScore = totalScore;
this.gamesPlayed = gamesPlayed;
// No need to return, but you can use `return this;` if you want
}
By convention, constructor names begin with an uppercase letter.
The advantage of using constructors is that the instances inherit from GamePlayer.prototype
. Then, you can define properties there and make them available in all instances
Update:
I use Compare plugin 2 for notepad++ 7.5 and newer versions. Notepad++ 7.5 and newer versions does not have plugin manager. You have to download and install plugins manually. And YES it matters if you use 64bit or 32bit (86x).
So Keep in mind, if you use 64 bit version of Notepad++, you should also use 64 bit version of plugin, and the same valid for 32bit.
I wrote a guideline how to install it:
Note:
It is also possible to drag and drop the plugin.dll
file directly in plugin folder.
64bit:%programfiles%\Notepad++\plugins
32bit:%programfiles(x86)%\Notepad++\plugins
Update Thanks to @TylerH with this update: Notepad++ Now has "Plugin Admin" as a replacement for the old Plugin Manager. But this method (answer) is still valid for adding plugins manually for almost any Notepad++ plugins.
Disclaimer: the link of this guideline refer to my personal web site.
I'm reading the Pragmatic Programmers book "Groovy Recipes: Greasing the wheels of Java" by Scott Davis, Copyright 2008 and printed in April of the same year.
It's a bit out of date but the book makes it clear that Groovy is literally an extension of Java. I can write Java code that functions exactly like Java and rename the file *.groovy and it works fine. According to the book, the reverse is true if I include the requisite libraries. So far, experimentation seems to bear this out.
<asp:Button ID="btnGet" runat="server" Text="Get" OnClick="btnGet_Click" OnClientClick="retun callMethod();" />
<script type="text/javascript">
function callMethod() {
//your logic should be here and make sure your logic code note returing function
return false;
}
</script>
Another example is, you have class like :
@obc class Album: NSObject {
let name:String
let singer:Singer
let artwork:URL
let playingSong:Song
// ...
class func getCurrentlyPlayingSongLyric(duration: Int = 0) -> String {
// ...
return playingSong.lyric
}
}
you will also get the same type of error like :
instance member x cannot be used on type x.
It's because you assign your method with "class" keyword (which makes your method a type method) and using like :
Album.getCurrentlyPlayingSongLyric(duration: 5)
but who set the playingSong variable before? Ok. You shouldn't use class keyword for that case :
// ...
func getCurrentlyPlayingSongLyric(duration: Int = 0) -> String {
// ...
return playingSong.lyric
}
// ...
Now you're free to go.

Right click on your selected table -> Modify
Right click on the field you want to set as PK --> Set Primary Key
Under Column Properties set "Identity Specification" to Yes, then specify the starting value and increment value.
Then in the future if you want to be able to just script this kind of thing out you can right click on the table you just modified and select
"SCRIPT TABLE AS" --> CREATE TO
so that you can see for yourself the correct syntax to perform this action.
You have strange expectations. If you gave the chain of arguments that led you to them, we might spot the flaw in them. As it is, I can only give a short primer on generics, hoping to touch on the points you might have misunderstood.
ArrayList<? extends Object>
is an ArrayList whose type parameter is known to be Object
or a subtype thereof. (Yes, extends in type bounds has a meaning other than direct subclass). Since only reference types can be type parameters, this is actually equivalent to ArrayList<?>
.
That is, you can put an ArrayList<String>
into a variable declared with ArrayList<?>
. That's why a1.add(3)
is a compile time error. a1
's declared type permits a1
to be an ArrayList<String>
, to which no Integer
can be added.
Clearly, an ArrayList<?>
is not very useful, as you can only insert null into it. That might be why the Java Spec forbids it:
It is a compile-time error if any of the type arguments used in a class instance creation expression are wildcard type arguments
ArrayList<ArrayList<?>>
in contrast is a functional data type. You can add all kinds of ArrayLists into it, and retrieve them. And since ArrayList<?>
only contains but is not a wildcard type, the above rule does not apply.
You might have 10,000 users total, but that's not the same as concurrent users. In this context, concurrent scripts being run.
For example, if your visitor visits index.php, and it makes a database query to get some user details, that request might live for 250ms. You can limit how long those MySQL connections live even further by opening and closing them only when you are querying, instead of leaving it open for the duration of the script.
While it is hard to make any type of formula to predict how many connections would be open at a time, I'd venture the following:
You probably won't have more than 500 active users at any given time with a user base of 10,000 users. Of those 500 concurrent users, there will probably at most be 10-20 concurrent requests being made at a time.
That means, you are really only establishing about 10-20 concurrent requests.
As others mentioned, you have nothing to worry about in that department.
The short answer is that ol
elements are not legally allowed inside p
elements.
To see why, let's go to the spec! If you can get comfortable with the HTML spec, it will answer many of your questions and curiosities. You want to know if an ol
can live inside a p
. So…
Categories: Flow content, Palpable content.
Content model: Phrasing content.
Categories: Flow content.
Content model: Zero or more li and script-supporting elements.
The first part says that p
elements can only contain phrasing content (which are “inline” elements like span
and strong
).
The second part says ol
s are flow content (“block” elements like p
and div
). So they can't be used inside a p
.
ol
s and other flow content
can be used in in some other elements like div
:
Categories: Flow content, Palpable content.
Content model: Flow content.
If python -m pip install --upgrade pip==9.0.3

Close your IDE if you have it open.
Press 'Repair' on Python 3.
In some cases adding "Option Strict On" in VB.NET and resolving all issues it finds by proper casting has solved this problem for me.
Here is a simple and clear example of how this works
Regex: ([a-zA-Z0-9]+)([\s]+)([a-zA-Z ]+)([\s]+)([0-9]+)
String: "!* UserName10 John Smith 01123 *!"
group(0): UserName10 John Smith 01123
group(1): UserName10
group(2):
group(3): John Smith
group(4):
group(5): 01123
As you can see, I have created FIVE groups which are each enclosed in parentheses.
I included the !* and *! on either side to make it clearer. Note that none of those characters are in the RegEx and therefore will not be produced in the results. Group(0) merely gives you the entire matched string (all of my search criteria in one single line). Group 1 stops right before the first space because the space character was not included in the search criteria. Groups 2 and 4 are simply the white space, which in this case is literally a space character, but could also be a tab or a line feed etc. Group 3 includes the space because I put it in the search criteria ... etc.
Hope this makes sense.
There are built-in functions in Python for "right" and "left", if you are looking for a boolean result.
str = "this_is_a_test"
left = str.startswith("this")
print(left)
> True
right = str.endswith("test")
print(right)
> True
Are you trying to pass the command line arguments to the program AS you launch it? I am working on something right now that does exactly this, and it was a lot simpler than I thought. If I go into the command line, and type
C:\folder\app.exe/xC:\folder\file.txt
then my application launches, and creates a file in the specified directory with the specified name.
I wanted to do this through a Powershell script on a remote machine, and figured out that all I needed to do was put
$s = New-PSSession -computername NAME -credential LOGIN
Invoke-Command -session $s -scriptblock {C:\folder\app.exe /xC:\folder\file.txt}
Remove-PSSession $s
(I have a bunch more similar commands inside the session, this is just the minimum it requires to run) notice the space between the executable, and the command line arguments. It works for me, but I am not sure exactly how your application works, or if that is even how you pass arguments to it.
*I can also have my application push the file back to my own local computer by changing the script-block to
C:\folder\app.exe /x"\\LocalPC\DATA (C)\localfolder\localfile.txt"
You need the quotes if your file-path has a space in it.
EDIT: actually, this brought up some silly problems with Powershell launching the application as a service or something, so I did some searching, and figured out that you can call CMD to execute commands for you on the remote computer. This way, the command is carried out EXACTLY as if you had just typed it into a CMD window on the remote machine. Put the command in the scriptblock into double quotes, and then put a cmd.exe /C before it. like this:
cmd.exe /C "C:\folder\app.exe/xC:\folder\file.txt"
this solved all of the problems that I have been having recently.
EDIT EDIT: Had more problems, and found a much better way to do it.
start-process -filepath C:\folder\app.exe -argumentlist "/xC:\folder\file.txt"
and this doesn't hang up your terminal window waiting for the remote process to end. Just make sure you have a way to terminate the process if it doesn't do that on it's own. (mine doesn't, required the coding of another argument)

I think you can use db.collection.distinct(fields,query)
You will be able to get the distinct values in your case for NetworkID.
It should be something like this :
Db.collection.distinct('NetworkID')
TagLib Sharp has support for reading ID3 tags.
If it's a table.
pd.read_table("path/to/file", sep="\t", index_col=0, skiprows=17)
Object* o; o = new Object();
Object* o = new Object();
Both these statement creates the object in the heap memory since you are creating the object using "new".
To be able to make the object creation happen in the stack, you need to follow this:
Object o;
Object *p = &o;
File -> Source Control -> Advanced -> Change Source Control and then unbind and/or disconnect all projects and the solution.
This should remove all bindings from the solution and project files. (After this you can switch the SCC provider in Tools -> Options -> Source Control -> Plug-in Selection).
The SCC specification prescribes that all SCC providers should implement this behavior. (I only tested it for VSS, TFS and AnkhSVN)
Also try it by turning off the firewall, and similar services. It worked for me!
Just add this function and call it, it will convert List to DataTable.
public static DataTable ToDataTable<T>(List<T> items)
{
DataTable dataTable = new DataTable(typeof(T).Name);
//Get all the properties
PropertyInfo[] Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);
foreach (PropertyInfo prop in Props)
{
//Defining type of data column gives proper data table
var type = (prop.PropertyType.IsGenericType && prop.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>) ? Nullable.GetUnderlyingType(prop.PropertyType) : prop.PropertyType);
//Setting column names as Property names
dataTable.Columns.Add(prop.Name, type);
}
foreach (T item in items)
{
var values = new object[Props.Length];
for (int i = 0; i < Props.Length; i++)
{
//inserting property values to datatable rows
values[i] = Props[i].GetValue(item, null);
}
dataTable.Rows.Add(values);
}
//put a breakpoint here and check datatable
return dataTable;
}
I would strongly recommend not using the default file loading as it is horrendously slow. You should look into the numpy functions and the IOpro functions (e.g. numpy.loadtxt()).
http://docs.scipy.org/doc/numpy/user/basics.io.genfromtxt.html
https://store.continuum.io/cshop/iopro/
Then you can break your pairwise operation into chunks:
import numpy as np
import math
lines_total = n
similarity = np.zeros(n,n)
lines_per_chunk = m
n_chunks = math.ceil(float(n)/m)
for i in xrange(n_chunks):
for j in xrange(n_chunks):
chunk_i = (function of your choice to read lines i*lines_per_chunk to (i+1)*lines_per_chunk)
chunk_j = (function of your choice to read lines j*lines_per_chunk to (j+1)*lines_per_chunk)
similarity[i*lines_per_chunk:(i+1)*lines_per_chunk,
j*lines_per_chunk:(j+1)*lines_per_chunk] = fast_operation(chunk_i, chunk_j)
It's almost always much faster to load data in chunks and then do matrix operations on it than to do it element by element!!
you can use call back function, like this
$this->form_validation->set_rules('userfile', 'Document', 'callback_file_selected_test');
if ($this->form_validation->run() == FALSE) {
//error
}
else{
// success
}
function file_selected_test(){
$this->form_validation->set_message('file_selected_test', 'Please select file.');
if (empty($_FILES['userfile']['name'])) {
return false;
}else{
return true;
}
}

If you are currently using the MongoDB 3.3 Repository (as officially currently suggested by MongoDB website) you should take in consideration that the package name used for version 3.3 is:
mongodb-org-unstable
Then the proper installation command for this version will be:
sudo apt-get install -y mongodb-org-unstable
Considering this, I will rather suggest to use the current latest stable version (v3.2) until the v3.3 becomes stable, the commands to install it are listed below:
Download the v3.2 Repository key:
wget -qO - https://www.mongodb.org/static/pgp/server-3.2.asc | sudo apt-key add -
If you work with Ubuntu 12.04 or Mint 13 add the following repository:
echo "deb http://repo.mongodb.org/apt/ubuntu precise/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
If you work with Ubuntu 14.04 or Mint 17 add the following repository:
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
If you work with Ubuntu 16.04 or Mint 18 add the following repository:
echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
Update the package list and install mongo:
sudo apt-get update
sudo apt-get install -y mongodb-org

) suggests a 32-bit executable which requires 32-bit libraries.
These seem not to be present on your system, so you need to install them manually.
The package name depends on your distribution, for Debian it's ia32-libs
, for Fedora libstdc++.<version>.i686
.
If you do not want to install Xcode and/or MacPorts/Fink/Homebrew, you could always use the standalone installer: https://sourceforge.net/projects/git-osx-installer/
SQL Server also accepts the simpler notation of:
SELECT A.F,
B.G,
C.H
FROM TABLE_A A,
TABLE_B B,
TABLE_C C
WHERE A.X = B.X
AND B.Y = C.Y
Using this simpler notation, one does not need to bother about the difference between inner and cross joins. Instead of two "ON" clauses, there is a single "WHERE" clause that does the job. If you have any difficulty in figuring out which "JOIN" "ON" clauses go where, abandon the "JOIN" notation and use the simpler one above.
It is not cheating.
For embeding youtube video into your angularjs page, you can simply use following filter for your video
app.filter('scrurl', function($sce) {_x000D_
return function(text) {_x000D_
text = text.replace("watch?v=", "embed/");_x000D_
return $sce.trustAsResourceUrl(text);_x000D_
};_x000D_
});
_x000D_
<iframe class="ytplayer" type="text/html" width="100%" height="360" src="{{youtube_url | scrurl}}" frameborder="0"></iframe>

Factory classes are more heavyweight, but give you certain advantages. In cases when you need to build your objects from multiple, raw data sources they allow you to encapsulate only the building logic (and maybe the aggregation of the data) in one place. There it can be tested in abstract without being concerned with the object interface.
I have found this a useful pattern, particularly where I am unable to replace and inadequate ORM and want to efficiently instantiate many objects from DB table joins or stored procedures.
Config is written to .npmrc
files so just delete it. NPM looks up config in this order, setting in the next overwrites the previous one. So make sure there might be global config that usually is overwritten in per-project that becomes active after you have deleted the per-project config file. npm config list
will allways list the active config.

hibernate3.HibernateQueryException: Books is not mapped [SELECT COUNT(*) FROM Books];
Hibernate is trying to say that it does not know an entity named "Books". Let's look at your entity:
@javax.persistence.Entity
@javax.persistence.Table(name = "Books")
public class Book {
Right. The table name for Book
has been renamed to "Books" but the entity name is still "Book" from the class name. If you want to set the entity name, you should use the @Entity
annotation's name instead:
// this allows you to use the entity Books in HQL queries
@javax.persistence.Entity(name = "Books")
public class Book {
That sets both the entity name and the table name.
The opposite problem happened to me when I was migrating from the Person.hbm.xml
file to using the Java annotations to describe the hibernate fields. My old XML file had:
<hibernate-mapping package="...">
<class name="Person" table="persons" lazy="true">
...
</hibernate-mapping>
And my new entity had a @Entity(name=...)
which I needed to set the name of the table.
// this renames the entity and sets the table name
@javax.persistence.Entity(name = "persons")
public class Person {
...
What I then was seeing was HQL errors like:
QuerySyntaxException: Person is not mapped
[SELECT id FROM Person WHERE id in (:ids)]
The problem with this was that the entity name was being renamed to persons
as well. I should have set the table name using:
// no name = here so the entity can be used as Person
@javax.persistence.Entity
// table name specified here
@javax.persistence.Table(name = "persons")
public class Person extends BaseGeneratedId {
Hope this helps others.
Use:
function random_color(format)
{
var rint = Math.round(0xffffff * Math.random());
switch(format)
{
case 'hex':
return ('#0' + rint.toString(16)).replace(/^#0([0-9a-f]{6})$/i, '#$1');
break;
case 'rgb':
return 'rgb(' + (rint >> 16) + ',' + (rint >> 8 & 255) + ',' + (rint & 255) + ')';
break;
default:
return rint;
break;
}
}
Updated version:
function random_color( format ){
var rint = Math.floor( 0x100000000 * Math.random());
switch( format ){
case 'hex':
return '#' + ('00000' + rint.toString(16)).slice(-6).toUpperCase();
case 'hexa':
return '#' + ('0000000' + rint.toString(16)).slice(-8).toUpperCase();
case 'rgb':
return 'rgb(' + (rint & 255) + ',' + (rint >> 8 & 255) + ',' + (rint >> 16 & 255) + ')';
case 'rgba':
return 'rgba(' + (rint & 255) + ',' + (rint >> 8 & 255) + ',' + (rint >> 16 & 255) + ',' + (rint >> 24 & 255)/255 + ')';
default:

DateTime values should be inserted as if they are strings surrounded by single quotes:
'20100301'
SQL Server allows for many accepted date formats and it should be the case that most development libraries provide a series of classes or functions to insert datetime values properly. However, if you are doing it manually, it is important to distinguish the date format using DateFormat
and to use generalized format:
Set DateFormat MDY --indicates the general format is Month Day Year
Insert Table( DateTImeCol )
Values( '2011-03-12' )
By setting the dateformat, SQL Server now assumes that my format is YYYY-MM-DD
instead of YYYY-DD-MM
.
SQL Server also recognizes a generic format that is always interpreted the same way: YYYYMMDD
e.g. 20110312
.
If you are asking how to insert the current date and time using T-SQL, then I would recommend using the keyword CURRENT_TIMESTAMP
. For example:
Insert Table( DateTimeCol )
Values( CURRENT_TIMESTAMP )
The best way to get all friends (who are using the App too, of course) with correct picture sizes is to use field expansion, either with one of the size tags (square, small, normal, large):
/me/friends?fields=picture.type(large)
(edit: this does not work anymore)
...or you can specify the width/height:
me/friends?fields=picture.width(100).height(100)
Btw, you can also write it like this:
me?fields=friends{picture.type(large)}

I was trying to achieve this but in the context of a MAVEN build. As part of my pom.xml
configuration, I had a reference to an environment variable as part of a path to a local JAR:
<dependency>
<groupId>the group id</groupId>
<artifactId>the artifact id</artifactId>
<version>the version</version>
<scope>system</scope>
<systemPath>${env.MY_ENV_VARIABLE}/the_local_jar_archive.jar</systemPath>
</dependency>
To compile my project, I had to define the environment variable as part of the run configuration for the maven build as explained by Max's answer. I was able to launch the maven compilation and the project would compile just fine.
However, as this environment variable involves some dependencies, the default "problems" view of Eclipse (where compilation errors/warnings usually show) would still show errors along the lines of Could not find artifact
and systemPath should be an absolute path but is ${env.MY_ENV_VARIABLE}/the_local_jar_archive.jar
.
How I fixed it
Go into Window -> Preferences -> General -> Worksapce -> Linked Resources
and define a new path variable.
Finally, in my case I just needed to Right click on my pom.xml
file, select Maven -> Update Project
and the errors disappeared from the "Problems" view.
$date = DateTime::createFromFormat("Y-m-d", "2068-06-15");
echo $date->format("Y");
The DateTime class does not use an unix timestamp internally, so it han handle dates before 1970 or after 2038.
Got it! Solved the issue modifying the user properties in security session of SQL Server. In SQL Server Management, go into security -> Logon -> Choose the user used for DB connection and go into his properties. Go to "Securators" tab and look for line "Connect SQL", mark "Grant" option and take a try. It works for me!

You need to add the command 'go' after you set the identity insert. Example:
SET IDENTITY_INSERT sometableWithIdentity ON
go
INSERT sometableWithIdentity (IdentityColumn, col2, col3, ...)
VALUES (AnIdentityValue, col2value, col3value, ...)
SET IDENTITY_INSERT sometableWithIdentity OFF
go
You can use DISTINCT
like that
mysql_query("SELECT DISTINCT(ticket_id), column1, column2, column3
FROM temp_tickets
ORDER BY ticket_id");
On my mac, the following inserts a single 'n' instead of newline:
sed 's/regexp/\n&/g'
This replaces with newline:
sed "s/regexp/\\`echo -e '\n\r'`/g"
Creating an isolate scope is undesirable. I would avoid using the scope attribute and do something like this. scope:true gives you a new child scope but not isolate. Then use parse to point a local scope variable to the same object the user has supplied to the ngModel attribute.
app.directive('myDir', ['$parse', function ($parse) {
return {
restrict: 'EA',
scope: true,
link: function (scope, elem, attrs) {
if(!attrs.ngModel) {return;}
var model = $parse(attrs.ngModel);
scope.model = model(scope);
}
};
}]);
Not sure if this answers your question or not. Sorry if not
To get the error reported from the mysql database about your query you need to use your connection object as the focus.
so:
echo $mysqliDatabaseConnection->error
would echo the error being sent from mysql about your query.
Hope that helps
Use a different tool. Something like Wolfram Alpha, Maple, R, Octave, Matlab or any other algebra software package.
As a beginner you should probably not attempt to solve such a non-trivial problem.
The answers so far are obviously great for the reproducibility part. This is merely to clarify that a reproducible example cannot and should not be the sole component of a question. Don't forget to explain what you want it to look like and the contours of your problem, not just how you have attempted to get there so far. Code is not enough; you need words also.
Here's a reproducible example of what to avoid doing (drawn from a real example, names changed to protect the innocent):

If you want to plot a Pandas dataframe and want to remove the legend, add legend=None as parameter to the plot command.

import matplotlib.pyplot as plt
df2 = pd.DataFrame(np.random.randn(10, 5))
df2.plot(legend=None)
plt.show()
Note that if typing if ( exists $hash{ key } )
isn’t too much work for you (which I prefer to use since the matter of interest is really the presence of a key rather than the truthiness of its value), then you can use the short and sweet
@hash{@key} = ();
I agree with @bortunac's solution. my.conf is mysql specific while netstat will provide you with all the listening ports.
Perhaps use both, one to confirm which is port set for mysql and the other to check that the system is listening through that port.
My client uses CentOS 6.6 and I have found the my.conf file under /etc/, so I used:
grep port /etc/my.conf
(CentOS 6.6)
Could also potentially use this script to use the system time in a variable
now=$(date +"%m_%d_%Y_%M:%S")
Which outputs as

I think you can use display as grid:
.parent { display: grid };
If you don't mind muddying your references a bit, you can include Microsoft.Visualbasic,
and use this very short way.
Display the MessageBox
(new System.Threading.Thread(CloseIt)).Start();
MessageBox.Show("HI");
CloseIt Function:
public void CloseIt()
{
System.Threading.Thread.Sleep(2000);
Microsoft.VisualBasic.Interaction.AppActivate(
System.Diagnostics.Process.GetCurrentProcess().Id);
System.Windows.Forms.SendKeys.SendWait(" ");
}
Now go wash your hands!
I think you want something along the line of:
Parent:
<Editor name={this.state.fileData} />
Editor:
var Editor = React.createClass({
displayName: 'Editor',
propTypes: {
name: React.PropTypes.string.isRequired
},
getInitialState: function() {
return {
value: this.props.name
};
},
handleChange: function(event) {
this.setState({value: event.target.value});
},
render: function() {
return (
<form id="noter-save-form" method="POST">
<textarea id="noter-text-area" name="textarea" value={this.state.value} onChange={this.handleChange} />
<input type="submit" value="Save" />
</form>
);
}
});
This is basically a direct copy of the example provided on https://facebook.github.io/react/docs/forms.html
Update for React 16.8:
import React, { useState } from 'react';
const Editor = (props) => {
const [value, setValue] = useState(props.name);
const handleChange = (event) => {
setValue(event.target.value);
};
return (
<form id="noter-save-form" method="POST">
<textarea id="noter-text-area" name="textarea" value={value} onChange={handleChange} />
<input type="submit" value="Save" />
</form>
);
}
Editor.propTypes = {
name: PropTypes.string.isRequired
};
Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:
EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")
After that you can do this:
EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )
R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.
Both VS Code extensions can be used:

You can also use this code with support for loading error:
$("img").on('load', function() {
// do stuff on success
})
.on('error', function() {
// do stuff on smth wrong (error 404, etc.)
})
.each(function() {
if(this.complete) {
$(this).load();
} else if(this.error) {
$(this).error();
}
});
how to have a click event outside of the dropdown menu so that it close the dropdown menu ? Heres the code
$(document).click(function (e) {

//check if the clicked area is dropDown or not
if (container.has(e.target).length === 0) {
$('.subMenu').hide();

=(((A1/60)/60)/24)+DATE(1970,1,1)+(-5/24)
assuming A1
is the cell where your time stamp is located and dont forget to adjust to account for the time zone you are in (5 assuming you are on EST)
You can easily do that using an async wait method in javascript.

You can use:
npm show {pkg} version
(so npm show express version

Runnable is just an interface, which provides the method run. Threads are implementations and use Runnable to call the method run().
Answer given by Abid Rahman K is not completely correct. I also tried it and found very helpful but got stuck.
This is how I copy image with a given mask.
x, y = np.where(mask!=0)
pts = zip(x, y)
# Assuming dst and src are of same sizes
for pt in pts:
dst[pt] = src[pt]
This is a bit slow but gives correct results.
EDIT:
Pythonic way.
idx = (mask!=0)
dst[idx] = src[idx]
This took me a while to figure out so this is how I got it working - Angular WebAPI ASP Routing without the # for SEO
Add $locationProvider.html5Mode(true); to app.config
I needed a certain controller (which was in the home controller) to be ignored for uploading images so I added that rule to RouteConfig
routes.MapRoute(
name: "Default2",
url: "Home/{*.}",
defaults: new { controller = "Home", action = "SaveImage" }
);
In Global.asax add the following - making sure to ignore api and image upload paths let them function as normal otherwise reroute everything else.
private const string ROOT_DOCUMENT = "/Index.html";
protected void Application_BeginRequest(Object sender, EventArgs e)
{
var path = Request.Url.AbsolutePath;
var isApi = path.StartsWith("/api", StringComparison.InvariantCultureIgnoreCase);
var isImageUpload = path.StartsWith("/home", StringComparison.InvariantCultureIgnoreCase);
if (isApi || isImageUpload)
return;
string url = Request.Url.LocalPath;
if (!System.IO.File.Exists(Context.Server.MapPath(url)))
Context.RewritePath(ROOT_DOCUMENT);
}
Make sure to use $location.url('/XXX') and not window.location ... to redirect
Reference the CSS files with absolute path
and not
<link href="app/content/bootstrapwc.css" rel="stylesheet" />
Final note - doing it this way gave me full control and I did not need to do anything to the web config.
Hope this helps as this took me a while to figure out.
console.dir(object)
:
Displays an interactive listing of the properties of a specified JavaScript object. This listing lets you use disclosure triangles to examine the contents of child objects.
Note that the console.dir()
feature is non-standard. See MDN Web Docs
You can do this with your axios by setting relative path to the corresponding images folder. I have done this for getting a json file. You can try the same method for an image file, you may refer these examples
If you have already set an axios instance with baseurl as a server in different domain, you will have to use the full path of the static file server where you deploy the web application.
axios.get('http://localhost:3000/assets/samplepic.png').then((response) => {
console.log(response)
}).catch((error) => {
console.log(error)
})
If the image is found the response will be 200 and if not, it will be 404.
Also, if the image file is present in assets folder inside src, you can do a require, get the path and do the above call with that path.
var SampleImagePath = require('./assets/samplepic.png');
axios.get(SampleImagePath).then(...)
Make sure your solutions startup project has the correct connectionstring in the config file. Or set the -StartUpProjectName parameter when executing the update-database command. The -StartUpProjectName parameter specifies the configuration file to use for named connection strings. If omitted, the specified project’s configuration file is used.

To answer the question "how can I find out if a given index in that dict has already been set to a non-None value", I would prefer this:
try:
nonNone = my_dict[key] is not None
except KeyError:
nonNone = False
This conforms to the already invoked concept of EAFP (easier to ask forgiveness then permission). It also avoids the duplicate key lookup in the dictionary as it would in key in my_dict and my_dict[key] is not None
what is interesting if lookup is expensive.
For the actual problem that you have posed, i.e. incrementing an int if it exists, or setting it to a default value otherwise, I also recommend the
my_dict[key] = my_dict.get(key, default) + 1
as in the answer of Andrew Wilkinson.
There is a third solution if you are storing modifyable objects in your dictionary. A common example for this is a multimap, where you store a list of elements for your keys. In that case, you can use:
my_dict.setdefault(key, []).append(item)
If a value for key does not exist in the dictionary, the setdefault method will set it to the second parameter of setdefault. It behaves just like a standard my_dict[key], returning the value for the key (which may be the newly set value).
malloc()
, we need to include <stdlib.h>
or
<alloc.h>
in the program which is not required for new
.new
and delete
can be overloaded but malloc
can not.new
, we can pass the address where we want to
allocate memory but this is not possible in case of malloc
.you can use @Component
@RequiredArgsConstructor
@Component
@Slf4j
public class BeerLoader implements CommandLineRunner {
//declare
@Override
public void run(String... args) throws Exception {
//some code here
}
Just a shot in the dark(since you did not share the compiler
initialization code with us): the way you retrieve the compiler
causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE
.
If you really mean small caps, then no, that is not possible – just as it isn’t possible to convert text to bold or italic in any text editor (as opposed to word processor). If you want to convert text to lowercase, create a visual block and press u
(or U
to convert to uppercase). Tilde (~
) in command mode reverses case of the character under the cursor.
If you want to see all text in Vim in small caps, you might want to look at the guifont
option, or type :set guifont=*
if your Vim flavour supports GUI font chooser.
Working example. Notes below.
class Animal {
constructor(public name) {
}
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
move() {
alert(this.name + " is Slithering...");
super.move(5);
}
}
class Horse extends Animal {
move() {
alert(this.name + " is Galloping...");
super.move(45);
}
}
var sam = new Snake("Sammy the Python");
var tom: Animal = new Horse("Tommy the Palomino");
sam.move();
tom.move(34);
You don't need to manually assign the name to a public variable. Using public name
in the constructor definition does this for you.
You don't need to call super(name)
from the specialised classes.
Using this.name
works.
Notes on use of super
.
This is covered in more detail in section 4.9.2 of the language specification.
The behaviour of the classes inheriting from Animal
is not dissimilar to the behaviour in other languages. You need to specify the super
keyword in order to avoid confusion between a specialised function and the base class function. For example, if you called move()
or this.move()
you would be dealing with the specialised Snake
or Horse
function, so using super.move()
explicitly calls the base class function.
There is no confusion of properties, as they are the properties of the instance. There is no difference between super.name
and this.name
- there is simply this.name
. Otherwise you could create a Horse that had different names depending on whether you were in the specialized class or the base class.
Consider these filenames:
C:\temp\file.txt
- This is a path, an absolute path, and a canonical path.
.\file.txt
- This is a path. It's neither an absolute path nor a canonical path.
C:\temp\myapp\bin\..\\..\file.txt
- This is a path and an absolute path. It's not a canonical path.
A canonical path is always an absolute path.
Converting from a path to a canonical path makes it absolute (usually tack on the current working directory so e.g. ./file.txt
becomes c:/temp/file.txt
). The canonical path of a file just "purifies" the path, removing and resolving stuff like ..\
and resolving symlinks (on unixes).
Also note the following example with nio.Paths:
String canonical_path_string = "C:\\Windows\\System32\\";
String absolute_path_string = "C:\\Windows\\System32\\drivers\\..\\";
System.out.println(Paths.get(canonical_path_string).getParent());
System.out.println(Paths.get(absolute_path_string).getParent());
While both paths refer to the same location, the output will be quite different:
C:\Windows
C:\Windows\System32\drivers
Faster clearing than Arrays.fill is with this (From Fast Serialization Lib). I just use arrayCopy (is native) to clear the array:
static Object[] EmptyObjArray = new Object[10000];
public static void clear(Object[] arr) {
final int arrlen = arr.length;
clear(arr, arrlen);
}
public static void clear(Object[] arr, int arrlen) {
int count = 0;
final int length = EmptyObjArray.length;
while( arrlen - count > length) {
System.arraycopy(EmptyObjArray,0,arr,count, length);
count += length;
}
System.arraycopy(EmptyObjArray,0,arr,count, arrlen -count);
}
In my search for hotel APIs I have found only one API giving unrestricted open access to their hotel database and allowing you to book their hotels:
Expedia's EAN http://developer.ean.com/
You need to sign for their affiliate program, which is very easy. You get immediate access to their hotel databases plus you can make availability/booking requests with several response options, including JSON, which is more convenient and lightweight than the (unfortunately) more widespread XML.
As you immediately access their API, you can start developing and testing, but still need their approval to launch the site, basically to make sure it provides the needed quality and security, which is reasonable.
They also offer "deep linking", i.e. you may customize your requests by adding parameters. Then if it sufficient for your purpose (for mine it is not), you don't even need to store their content on your server.
I have also signed for HotelsCombined program: (link removed as this site doesn't seem to let me put more links)
However, they do not immediately allow you to use their API even for testing. From their answer:
"Apologies for the inconvenience caused, but it’s simply a business decision to limit access to our rich hotel content. Please kindly check back within the next 2-3 months, where we will be able to judge your traffic, and in turn judge your status on standard data feeds."
I have also signed for Booking.com affiliate program: (link removed as this site doesn't seem to let me put more links)
Unfortunately, again, they limit access, from their answer: "Please do note that, since there's a high amount of time and cost involved in the XML integration, we are only able to offer the XML integration to a small amount of partners with a high potential."
I did not explore Tripadvisor as they seem only to offer top 10 hotels and only as widgets, but most importantly for me, they wouldn't allow booking through them.
I've checked the hotelbase.org mentioned above, they have very extensive list but not as rich as by Expedia, also they don't seem to have images and don't allow booking either.

Values in VARCHAR columns are variable-length strings. The length can be specified as a value from 0 to 255 before MySQL 5.0.3, and 0 to 65,535 in 5.0.3 and later versions. The effective maximum length of a VARCHAR in MySQL 5.0.3 and later is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used.
- So ...
< MySQL 5.0.3 use TEXT
or
>= MySQL 5.0.3 use VARCHAR(2083)
Maybe you can use the [Integer] data annotation (If you use the DataAnnotationsExtensions http://dataannotationsextensions.org/) . However, this wil only check if the value is an integer, nót if it is filled in (So you may also need the [Required] attribute).
If you enable Unobtrusive Validation it will validate it clientside, but you should also use Modelstate.Valid in your POST action to decline it in case people have Javascript disabled.
In my case the error states that the assemly
Oracle.DataAccess, Version=2.112.3.0, Culture=neutral, PublicKeyToken=89b483f429c47342
is missing.
When I run gacutil.exe /l 'Oracle.DataAccess'
the result was:
The Global Assembly Cache contains the following assemblies:
Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342, processorArchitecture=x86
Number of items = 1
At this moment I have just installed the oracle client: win32_11gR2_client
Then I installed oracle developer tools ODTwithODAC112030_deleloper_tool
Now gacutil
is saying:
The Global Assembly Cache contains the following assemblies:
Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342, processorArchitecture=x86

Number of items = 2
Fixed, one totally missing assembly case
100% security of the source code and resources is not possible in Android. But, you can make little bit difficult for the reverse engineer. You can find more details on this in below links:

I found that The Boolean Expression Reducer is much easier to use than Logic Friday. Plus it doesn't require installation and is multi-platform (Java).
Also in Logic Friday the expression A | B
just returns 3 entries in truth table; I expected 4.
drop table if exists foo;
create table foo
(
id int unsigned not null auto_increment primary key,
val smallint unsigned not null default 0
)
engine=innodb;
drop procedure if exists load_foo_test_data;
delimiter #
create procedure load_foo_test_data()
begin
declare v_max int unsigned default 1000;
declare v_counter int unsigned default 0;
truncate table foo;
start transaction;
while v_counter < v_max do
insert into foo (val) values ( floor(0 + (rand() * 65535)) );
set v_counter=v_counter+1;
end while;
commit;
end #
delimiter ;
call load_foo_test_data();
select * from foo order by id;
You could also set between two dates:
Delete From tblAudit
WHERE Date_dat < DATEADD(day, -360, GETDATE())
GO
Delete From tblAudit
WHERE Date_dat > DATEADD(day, -60, GETDATE())
GO

download this app from here it will help you to rum all commands. I have run netcfg and it gives the result as attached in screen.
In the past, with VBA projects, I've used a label control with the background colored and adjust the size based on the progress. Some examples with similar approaches can be found in the following links:
Here is one that uses Excel's Autoshapes:
Hi if you are having dropdownlist like this
<select id="testID">
<option value="1">Value1</option>
<option value="2">Value2</option>
<option value="3">Value3</option>
<option value="4">Value4</option>
<option value="5">Value5</option>
<option value="6">Value6</option>
</select>
<input type="button" value="Get dropdown selected Value" onclick="getHTML();">
after giving id to dropdownlist you just need to add jquery code like this
function getHTML()
{
var display=$('#testID option:selected').html();
alert(display);
}
String join(List<Object> collection, String delimiter){
StringBuilder stringBuilder = new StringBuilder();
int size = collection.size();
for (Object value : collection) {
size --;
if(size > 0){
stringBuilder.append(value).append(delimiter);
}
}
return stringBuilder.toString();
}
Given the array of [1,2,3]
join(myArray, ",") // 1,2,3
I wanted to add to Joseph Kingry's answer. He provided the solution but at first I couldn't get it to work either and got a result just like Adhip Gupta. And then I realized that the route has to exist in the first place and the parameters need to match the route exactly. So I had an id and then a text parameter for my route which also needed to be included too.
Html.ActionLink(article.Title, "Login", "Item", new { id = article.ArticleID, title = article.Title }, null)
Before we'll begin, let's just remind that origin point is the Upper Left corner CGPoint
of a view.
An important thing to understand about views and parents.
Lets take a look at this simple code, a view controller that adds to it's view a black square:
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
createDummyView()
super.view.backgroundColor = UIColor.cyanColor();
}
func createDummyView(){
var subView = UIView(frame: CGRect(x: 15, y: 50, width: 50 , height: 50));
super.view.addSubview(subView);
view.backgroundColor = UIColor.blackColor()
}
}
This will create this view: the black rectangle origin and center does fit the same coordinates as it's parent
Now let's try to add subView another SubSubView, and giving subSubview same origin as subView, but make subSubView a child view of subView
We'll add this code:
var subSubView = UIView();
subSubView.frame.origin = subView.frame.origin;
subSubView.frame.size = CGSizeMake(20, 20);
subSubView.backgroundColor = UIColor.purpleColor()
subView.addSubview(subSubView)
And this is the result:
Because of this line:
subSubView.frame.origin = subView.frame.origin;
You expect for the purple rectangle's origin to be same as it's parent (the black rectangle) but it goes under it, and why is that? Because when you add a view to another view, the subView frame "world" is now it's parent BOUND RECTANGLE, if you have a view that it's origin on the main screen is at coords (15,15) for all it's sub views, the upper left corner will be (0,0)
This is why you need to always refer to a parent by it's bound rectangle, which is the "world" of it's subViews, lets fix this line to:
subSubView.frame.origin = subView.bounds.origin;
And see the magic, the subSubview is now located exactly in it's parent origin:
So, you like "ok I only wanted to center my view by my parents view, what's the big deal?" well, it isn't big deal, you just need to "translate" the parent Center point which is taken from it's frame to parent's bounds center by doing this:
subSubView.center = subView.convertPoint(subView.center, fromView: subSubView);
You're actually telling him "take parents view center, and convert it into subSubView world".
And you'll get this result:
include math.h and compile with gcc test.c -lm
-Xmx1024m -XX:MaxPermSize=512m -Xms512m
Add this parameter as argument in your server params
here's a small program which may help you:
import java.util.*;
public class DateDifference {
public static void main(String args[]){
DateDifference difference = new DateDifference();
}
DateDifference() {
Calendar cal1 = new GregorianCalendar();
Calendar cal2 = new GregorianCalendar();
cal1.set(2010, 12, 1);
cal2.set(2011, 9, 31);
System.out.println("Days= "+daysBetween(cal1.getTime(),cal2.getTime()));
}
public int daysBetween(Date d1, Date d2) {
return (int)( (d2.getTime() - d1.getTime()) / (1000 * 60 * 60 * 24));
}
}
If you are targeting Windows XP (v140_xp
), try installing Windows XP Support for C++.
Starting with Visual Studio 2012, the default toolset (v110) dropped support for Windows XP. As a result, a Windows.h
error can occur if your project is targeting Windows XP with the default C++ packages.
Check which Windows SDK version is specified in your project's Platform Toolset. (Project ? Properties ? Configuration Properties ? General
). If your Toolset ends in _xp
, you'll need to install XP support.
Open the Visual Studio Installer and click Modify for your version of Visual Studio. Open the Individual Components tab and scroll down to Compilers, build tools, and runtimes. Near the bottom, check Windows XP support for C++ and click Modify to begin installing.
Default parameter values must appear on the declaration, since that is the only thing that the caller sees.
EDIT: As others point out, you can have the argument on the definition, but I would advise writing all code as if that wasn't true.
It is happening Due to:
<p><script>var _nwls=[];if(window.jQuery&&window.jQuery.find){_nwls=jQuery.find(".fw_link_newWindow");}else{if(document.getElementsByClassName){_nwls=document.getElementsByClassName("fw_link_newWindow");}else{if(document.querySelectorAll){_nwls=document.querySelectorAll(".fw_link_newWindow");}else{document.write('<scr'+'ipt src="http://static.websimages.com/static/global/js/sizzle/sizzle.min.js"><\/scr'+'ipt>');if(window.Sizzle){_nwls=Sizzle(".fw_link_newWindow");}}}}var numlinks=_nwls.length;for(var i=0;i<numlinks;i++){_nwls[i].target="_blank";}</script></p>
Remove <p></p>
around the script.
hey guys i think what you are looking for is this one using select command. With this you can specify a RANGE GREATER THAN(>) OR LESSER THAN(<) IN MySQL WITH THIS:::::
select* from <**TABLE NAME**> where year(**COLUMN NAME**) > **DATE** OR YEAR(COLUMN NAME )< **DATE**;
FOR EXAMPLE:
select name, BIRTH from pet1 where year(birth)> 1996 OR YEAR(BIRTH)< 1989;
+----------+------------+
| name | BIRTH |
+----------+------------+
| bowser | 1979-09-11 |
| chirpy | 1998-09-11 |
| whistler | 1999-09-09 |
+----------+------------+
FOR SIMPLE RANGE LIKE USE ONLY GREATER THAN / LESSER THAN
mysql> select COLUMN NAME from <TABLE NAME> where year(COLUMN NAME)> 1996;
FOR EXAMPLE mysql>
select name from pet1 where year(birth)> 1996 OR YEAR(BIRTH)< 1989;
+----------+
| name |
+----------+
| bowser |
| chirpy |
| whistler |
+----------+
3 rows in set (0.00 sec)
To print the columns with a specific string, you use the // search pattern. For example, if you are looking for second columns that contains abc:
awk '$2 ~ /abc/'
... and if you want to print only a particular column:
awk '$2 ~ /abc/ { print $3 }'
... and for a particular line number:
awk '$2 ~ /abc/ && FNR == 5 { print $3 }'
I think he's using Python 3.0 and you're using Python 2.6.
