My Bots are running well against ReCaptcha.
Here my Solution.
Let your Bot do this Steps:
First write a Human Mouse Move Function to move your Mouse like a B-Spline (Ask me for Source Code). This is the most important Point.
Also use for better results a VPN like https://www.purevpn.com
For every Recpatcha do these Steps:
If you use VPN switch IP first
Clear all Browser Cookies
Clear all Browser Cache
Set one of these Useragents by Random:
a. Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)
b. Mozilla/5.0 (Windows NT 6.1; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0
5 Move your Mouse with the Human Mouse Move Funktion from a RandomPoint into the I am not a Robot Image every time with different 10x10 Randomrange
Then Click ever with random delay between
WM_LBUTTONDOWN
and
WM_LBUTTONUP
Take Screenshot from Image Captcha
Send Screenshot to
or
and let they solve.
After receiving click cooridinates from captcha solver use your Human Mouse move Funktion to move and Click Recaptcha Images
Use your Human Mouse Move Funktion to move and Click to the Recaptcha Verify Button
In 75% all trys Recaptcha will solved

I am just adding this kind of solution / quick fix so it won't get lost in case of a broken link.
Link to this solution "Want to add link How to resize the Google noCAPTCHA reCAPTCHA | The Geek Goddess" was provided by Vikram Singh Saini and simply outlines that you could use inline CSS to enforce framing of the iframe.
// Scale the frame using inline CSS
<div class="g-recaptcha" data-theme="light"
data-sitekey="XXXXXXXXXXXXX"
style="transform:scale(0.77);
-webkit-transform:scale(0.77);
transform-origin:0 0;
-webkit-transform-origin:0 0;
">
</div>
// Scale the images using a stylesheet
<style>
#rc-imageselect, .g-recaptcha {
transform:scale(0.77);
-webkit-transform:scale(0.77);
transform-origin:0 0;
-webkit-transform-origin:0 0;
}
</style>
A good option is to generate a recaptcha input for each form on the fly (I've done it with two but you could probably do three or more forms). I'm using jQuery, jQuery validation, and jQuery form plugin to post the form via AJAX, along with the Recaptcha AJAX API -
https://developers.google.com/recaptcha/docs/display#recaptcha_methods
When the user submits one of the forms:
Then, they can fill out the recaptcha and re-submit the form. If they decide to submit a different form instead, well, your code checks for existing recaptchas so you'll only have one recaptcha on the page at a time.
A clean CSS-only solution this would be:
input[type="radio"]:read-only {
pointer-events: none;
}
this is the source code about wraps:
WRAPPER_ASSIGNMENTS = ('__module__', '__name__', '__doc__')
WRAPPER_UPDATES = ('__dict__',)
def update_wrapper(wrapper,
wrapped,
assigned = WRAPPER_ASSIGNMENTS,
updated = WRAPPER_UPDATES):
"""Update a wrapper function to look like the wrapped function
wrapper is the function to be updated
wrapped is the original function
assigned is a tuple naming the attributes assigned directly
from the wrapped function to the wrapper function (defaults to
functools.WRAPPER_ASSIGNMENTS)
updated is a tuple naming the attributes of the wrapper that
are updated with the corresponding attribute from the wrapped

"""
for attr in assigned:
setattr(wrapper, attr, getattr(wrapped, attr))
for attr in updated:
getattr(wrapper, attr).update(getattr(wrapped, attr, {}))
# Return the wrapper so this can be used as a decorator via partial()
return wrapper

assigned = WRAPPER_ASSIGNMENTS,
updated = WRAPPER_UPDATES):
"""Decorator factory to apply update_wrapper() to a wrapper function

Well, according to the mysql_real_escape_string function reference page: "mysql_real_escape_string() calls MySQL's library function mysql_real_escape_string, which escapes the following characters: \x00, \n, \r, \, ', " and \x1a."
With that in mind, then the function given in the second link you posted should do exactly what you need:
function mres($value)
{
$search = array("\\", "\x00", "\n", "\r", "'", '"', "\x1a");
$replace = array("\\\\","\\0","\\n", "\\r", "\'", '\"', "\\Z");
return str_replace($search, $replace, $value);
}
I'm assuming the contents of src/main/resources/
is copied to WEB-INF/classes/
inside your .war at build time. If that is the case you can just do (substituting real values for the classname and the path being loaded).
URL sqlScriptUrl = MyServletContextListener.class
.getClassLoader().getResource("sql/script.sql");
I was also facing the same problem when I am using the facebook authentication method.
But I rectify that issue with following changes in Facebook api (Apps >> My App >> Basic
).
Then i gave that AppId and App Secret in my webpage.
So by clicking on login button, It ask for access permissions then it redirect it to give url (Website with Facebook Login ).
In Ubuntu18.04, the most easist way to get a core file is inputing the command below to stop the apport service.
sudo service apport stop
Then rerun the application, you will get dump file in current directory.
Here is the implementation of BCrypt which is working for me.
in spring-security.xml
<authentication-manager >
<authentication-provider ref="authProvider"></authentication-provider>
</authentication-manager>
<beans:bean id="authProvider" class="org.springframework.security.authentication.dao.DaoAuthenticationProvider">

<beans:property name="passwordEncoder" ref="encoder" />
</beans:bean>
<!-- For hashing and salting user passwords -->
<beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>
In java class
PasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
String hashedPassword = passwordEncoder.encode(yourpassword);

Hope this will help.

I know this is old but by far the easier solution is to just use
var temp = new Date("2010-08-17T12:09:36");
int match_position=text.indexOf(match);
Go ahead and add [STAThread] to the main entry of your application, this indicates the COM threading model is single-threaded apartment (STA)
example:
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new WebBrowser());
}
}
According to the documentation of the PropertyFile
task, you can append the generated properties to an existing file. You could have a properties file with just the comment line, and have the Ant task append the generated properties.
Using your code, this is how I would do it. I know an answer was chosen, just giving additional options.
data = json.loads('{"lat":444, "lon":555}')
ret = ''
for j in data:
ret = ret+" "+data[j]
return ret
When you use for in this manor you get the key of the object, not the value, so you can get the value, by using the key as an index.
For z-index to work, you also need to give it a position:
header {
width: 100%;
height: 100px;
background: url(../img/top.png) repeat-x;
z-index: 110;
position: relative;
}
JAX-RS but you can also use regular DOM that comes with standard Java
On Safari Mac for an HLS source, I needed to use the loadeddata event instead of the metadata event.
since your over
div doesn't have a positioning, the z-index doesn't know where and how to position it (and with respect to what?). Just change your over div's position to relative, so there is no side effects on that div and then the under div will obey to your will.
here is your example on jsfiddle: Fiddle
edit: I see someone already mentioned this answer!
From the docs
IF boolean-expression THEN
statements
ELSE
statements
END IF;
So in your above example the code should look as follows:
IF select count(*) from orders > 0
THEN
DELETE from orders
ELSE
INSERT INTO orders values (1,2,3);
END IF;
You were missing: END IF;
If you want to access redis
from the host (127.0.0.1), you have to use the ports
command.
redis:
build:
context: .
dockerfile: Dockerfile-redis
ports:
- "6379:6379"
Drop root privileges after you bind to port 80 (or 443).
This allows port 80/443 to remain protected, while still preventing you from serving requests as root:
function drop_root() {
process.setgid('nobody');
process.setuid('nobody');
}
A full working example using the above function:
var process = require('process');
var http = require('http');
var server = http.createServer(function(req, res) {
res.write("Success!");
res.end();
});
server.listen(80, null, null, function() {
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
drop_root();
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
});

Yes, use HashMap
... but in a specialised way: the trap I foresee in trying to use a HashMap
as a pseudo-Set
is the possible confusion between "actual" elements of the Map/Set
, and "candidate" elements, i.e. elements used to test whether an equal
element is already present. This is far from foolproof, but nudges you away from the trap:
class SelfMappingHashMap<V> extends HashMap<V, V>{
@Override
public String toString(){
// otherwise you get lots of "... object1=object1, object2=object2..." stuff
return keySet().toString();
}
@Override
public V get( Object key ){
throw new UnsupportedOperationException( "use tryToGetRealFromCandidate()");
}
@Override
public V put( V key, V value ){
// thorny issue here: if you were indavertently to `put`
// a "candidate instance" with the element already in the `Map/Set`:
// these will obviously be considered equivalent
assert key.equals( value );
return super.put( key, value );
}
public V tryToGetRealFromCandidate( V key ){
return super.get(key);
}
}
Then do this:
SelfMappingHashMap<SomeClass> selfMap = new SelfMappingHashMap<SomeClass>();
...
SomeClass candidate = new SomeClass();
if( selfMap.contains( candidate ) ){
SomeClass realThing = selfMap.tryToGetRealFromCandidate( candidate );
...
realThing.useInSomeWay()...
}
But... you now want the candidate
to self-destruct in some way unless the programmer actually immediately puts it in the Map/Set
... you'd want contains
to "taint" the candidate
so that any use of it unless it joins the Map
makes it "anathema". Perhaps you could make SomeClass
implement a new Taintable
interface.
A more satisfactory solution is a GettableSet, as below. However, for this to work you have either to be in charge of the design of SomeClass
in order to make all constructors non-visible (or... able and willing to design and use a wrapper class for it):
public interface NoVisibleConstructor {
// again, this is a "nudge" technique, in the sense that there is no known method of
// making an interface enforce "no visible constructor" in its implementing classes
// - of course when Java finally implements full multiple inheritance some reflection
// technique might be used...
NoVisibleConstructor addOrGetExisting( GettableSet<? extends NoVisibleConstructor> gettableSet );
};
public interface GettableSet<V extends NoVisibleConstructor> extends Set<V> {
V getGenuineFromImpostor( V impostor ); // see below for naming
}
Implementation:
public class GettableHashSet<V extends NoVisibleConstructor> implements GettableSet<V> {
private Map<V, V> map = new HashMap<V, V>();
@Override
public V getGenuineFromImpostor(V impostor ) {
return map.get( impostor );
}
@Override
public int size() {
return map.size();
}
@Override
public boolean contains(Object o) {
return map.containsKey( o );
}
@Override
public boolean add(V e) {
assert e != null;
V result = map.put( e, e );
return result != null;
}
@Override
public boolean remove(Object o) {
V result = map.remove( o );
return result != null;
}
@Override
public boolean addAll(Collection<? extends V> c) {
// for example:
throw new UnsupportedOperationException();
}
@Override
public void clear() {
map.clear();
}
// implement the other methods from Set ...
}
Your NoVisibleConstructor
classes then look like this:
class SomeClass implements NoVisibleConstructor {
private SomeClass( Object param1, Object param2 ){
// ...
}
static SomeClass getOrCreate( GettableSet<SomeClass> gettableSet, Object param1, Object param2 ) {
SomeClass candidate = new SomeClass( param1, param2 );
if (gettableSet.contains(candidate)) {
// obviously this then means that the candidate "fails" (or is revealed
// to be an "impostor" if you will). Return the existing element:
return gettableSet.getGenuineFromImpostor(candidate);
}
gettableSet.add( candidate );
return candidate;
}
@Override
public NoVisibleConstructor addOrGetExisting( GettableSet<? extends NoVisibleConstructor> gettableSet ){
// more elegant implementation-hiding: see below
}
}
PS one technical issue with such a NoVisibleConstructor
class: it may be objected that such a class is inherently final
, which may be undesirable. Actually you could always add a dummy parameterless protected
constructor:
protected SomeClass(){
throw new UnsupportedOperationException();
}
... which would at least let a subclass compile. You'd then have to think about whether you need to include another getOrCreate()
factory method in the subclass.
Final step is an abstract base class (NB "element" for a list, "member" for a set) like this for your set members (when possible - again, scope for using a wrapper class where the class is not under your control, or already has a base class, etc.), for maximum implementation-hiding:
public abstract class AbstractSetMember implements NoVisibleConstructor {
@Override
public NoVisibleConstructor
addOrGetExisting(GettableSet<? extends NoVisibleConstructor> gettableSet) {
AbstractSetMember member = this;
@SuppressWarnings("unchecked") // unavoidable!
GettableSet<AbstractSetMembers> set = (GettableSet<AbstractSetMember>) gettableSet;
if (gettableSet.contains( member )) {
member = set.getGenuineFromImpostor( member );
cleanUpAfterFindingGenuine( set );
} else {
addNewToSet( set );
}
return member;
}
abstract public void addNewToSet(GettableSet<? extends AbstractSetMember> gettableSet );
abstract public void cleanUpAfterFindingGenuine(GettableSet<? extends AbstractSetMember> gettableSet );
}
... usage is fairly obvious (inside your SomeClass
's static
factory method):
SomeClass setMember = new SomeClass( param1, param2 ).addOrGetExisting( set );
Taking the top answer, as well as the suggestions from its comments, and modifying it to use SecureString instead of String, test for all control keys, and not error or write an extra "*" to the screen when the password length is 0, my solution is:
public static SecureString getPasswordFromConsole(String displayMessage) {
SecureString pass = new SecureString();
Console.Write(displayMessage);
ConsoleKeyInfo key;
do {
key = Console.ReadKey(true);
// Backspace Should Not Work
if (!char.IsControl(key.KeyChar)) {
pass.AppendChar(key.KeyChar);
Console.Write("*");
} else {
if (key.Key == ConsoleKey.Backspace && pass.Length > 0) {
pass.RemoveAt(pass.Length - 1);
Console.Write("\b \b");
}
}
}
// Stops Receving Keys Once Enter is Pressed
while (key.Key != ConsoleKey.Enter);
return pass;
}
Basically when you hit 'return' on a function the function will stop and will not continue your iteration, so what you need to do is put it all on a list and then add it as a children of a widget
you can do something like this:
Widget getTextWidgets(List<String> strings)
{
List<Widget> list = new List<Widget>();
for(var i = 0; i < strings.length; i++){
list.add(new Text(strings[i]));
}
return new Row(children: list);
}
or even better, you can use .map() operator and do something like this:
Widget getTextWidgets(List<String> strings)
{
return new Row(children: strings.map((item) => new Text(item)).toList());
}
Try using max-width
instead of width
, the table will still calculate the width automatically.
Works even in ie11
(with ie8 compatibility mode).

max-width: 50px;_x000D_
overflow: hidden;_x000D_
text-overflow: ellipsis;_x000D_
white-space: nowrap;_x000D_
}

In my case , I used the 'is' a jQuery function, I had a HTML element with different css classes added , I was looking for a specific class in the middle of these , so I used the "is" a good alternative to check a class dynamically added to an html element , which already has other css classes, it is another good alternative.
simple example :
<!--element html-->
<nav class="cbp-spmenu cbp-spmenu-horizontal cbp-spmenu-bottom cbp-spmenu-open" id="menu">somethings here... </nav>
<!--jQuery "is"-->
$('#menu').is('.cbp-spmenu-open');
advanced example :
<!--element html-->
<nav class="cbp-spmenu cbp-spmenu-horizontal cbp-spmenu-bottom cbp-spmenu-open" id="menu">somethings here... </nav>
<!--jQuery "is"-->
if($('#menu').is('.cbp-spmenu-bottom.cbp-spmenu-open')){
$("#menu").show();
}
Sometimes you have to deal with bad written libraries or software, which need a "real" empty and existing directory. Putting a simple .gitignore
or .keep
might break them and cause a bug. The following might help in these cases, but no guarantee...
First create the needed directory:
mkdir empty
Then you add a broken symbolic link to this directory (but on any other case than the described use case above, please use a README
with an explanation):
ln -s .this.directory empty/.keep
To ignore files in this directory, you can add it in your root .gitignore
:
echo "/empty" >> .gitignore
To add the ignored file, use a parameter to force it:
git add -f empty/.keep
After the commit you have a broken symbolic link in your index and git creates the directory. The broken link has some advantages, since it is no regular file and points to no regular file. So it even fits to the part of the question "(that contains no files)", not by the intention but by the meaning, I guess:
find empty -type f
This commands shows an empty result, since no files are present in this directory. So most applications, which get all files in a directory usually do not see this link, at least if they do a "file exists" or a "is readable". Even some scripts will not find any files there:
$ php -r "var_export(glob('empty/.*'));"
array (
0 => 'empty/.',
1 => 'empty/..',
)
But I strongly recommend to use this solution only in special circumstances, a good written README
in an empty directory is usually a better solution. (And I do not know if this works with a windows filesystem...)
Remove a determinated string from start and end from a string.
s = '""Hello World""'
s.strip('""')
> 'Hello World'
I finally found out how to do this! Basically you need to run adb shell
first and then while you're in the shell run su
, which will switch the shell to run as root!
$: adb shell
$: su
The one problem I still have is that sqlite3 is not installed so the command is not recognized.
Cast one of the integers/both of the integer to float to force the operation to be done with floating point Math. Otherwise integer Math is always preferred. So:
1. double d = (double)5 / 20;
2. double v = (double)5 / (double) 20;
3. double v = 5 / (double) 20;
Note that casting the result won't do it. Because first division is done as per precedence rule.
double d = (double)(5 / 20); //produces 0.0
I do not think there is any problem with casting as such you are thinking about.
It depends on whether default path is set for data and log files or not.
If the path is set explicitly at Properties
=> Database Settings
=> Database default locations
then SQL server stores it at Software\Microsoft\MSSQLServer\MSSQLServer
in DefaultData
and DefaultLog
values.
However, if these parameters aren't set explicitly, SQL server uses Data and Log paths of master database.
Bellow is the script that covers both cases. This is simplified version of the query that SQL Management Studio runs.
Also, note that I use xp_instance_regread
instead of xp_regread
, so this script will work for any instance, default or named.
declare @DefaultData nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultData', @DefaultData output
declare @DefaultLog nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultLog', @DefaultLog output
declare @DefaultBackup nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'BackupDirectory', @DefaultBackup output
declare @MasterData nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer\Parameters', N'SqlArg0', @MasterData output
select @MasterData=substring(@MasterData, 3, 255)
select @MasterData=substring(@MasterData, 1, len(@MasterData) - charindex('\', reverse(@MasterData)))
declare @MasterLog nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer\Parameters', N'SqlArg2', @MasterLog output
select @MasterLog=substring(@MasterLog, 3, 255)
select @MasterLog=substring(@MasterLog, 1, len(@MasterLog) - charindex('\', reverse(@MasterLog)))
select
isnull(@DefaultData, @MasterData) DefaultData,
isnull(@DefaultLog, @MasterLog) DefaultLog,
isnull(@DefaultBackup, @MasterLog) DefaultBackup
You can achieve the same result by using SMO. Bellow is C# sample, but you can use any other .NET language or PowerShell.
using (var connection = new SqlConnection("Data Source=.;Integrated Security=SSPI"))
{
var serverConnection = new ServerConnection(connection);
var server = new Server(serverConnection);
var defaultDataPath = string.IsNullOrEmpty(server.Settings.DefaultFile) ? server.MasterDBPath : server.Settings.DefaultFile;
var defaultLogPath = string.IsNullOrEmpty(server.Settings.DefaultLog) ? server.MasterDBLogPath : server.Settings.DefaultLog;
}
It is so much simpler in SQL Server 2012 and above, assuming you have default paths set (which is probably always a right thing to do):
select
InstanceDefaultDataPath = serverproperty('InstanceDefaultDataPath'),
InstanceDefaultLogPath = serverproperty('InstanceDefaultLogPath')
By playing with parameters as -XX:PermSize
and -Xms
you can tune the performance of - for example - the startup of your application. I haven't looked at it recently, but a few years back the default value of -Xms
was something like 32MB (I think), if your application required a lot more than that it would trigger a number of cycles of fill memory - full garbage collect - increase memory etc until it had loaded everything it needed. This cycle can be detrimental for startup performance, so immediately assigning the number required could improve startup.
A similar cycle is applied to the permanent generation. So tuning these parameters can improve startup (amongst others).
WARNING The JVM has a lot of optimization and intelligence when it comes to allocating memory, dividing eden space and older generations etc, so don't do things like making -Xms
equal to -Xmx
or -XX:PermSize
equal to -XX:MaxPermSize
as it will remove some of the optimizations the JVM can apply to its allocation strategies and therefor reduce your application performance instead of improving it.
As always: make non-trivial measurements to prove your changes actually improve performance overall (for example improving startup time could be disastrous for performance during use of the application)
Extract (refactor) your statements. And use the magic of and
and or
to decide when to short-circuit.

Along with Environment.NewLine
and the literal \r\n
or just \n
you may also use a verbatim string in C#. These begin with @
and can have embedded newlines. The only thing to keep in mind is that "
needs to be escaped as ""
. An example:
string s = @"This is a string
that contains embedded new lines,
that will appear when this string is used."
Here is some pseudo-code to retrieve the following:

std::wstring strKeyDefaultValue;
GetStringRegKey(hKey, L"BinDir", strValueOfBinDir, L"bad");
GetStringRegKey(hKey, L"", strKeyDefaultValue, L"bad");
LONG GetDWORDRegKey(HKEY hKey, const std::wstring &strValueName, DWORD &nValue, DWORD nDefaultValue)
{
nValue = nDefaultValue;

{
DWORD nDefValue((bDefaultValue) ? 1 : 0);
DWORD nResult(nDefValue);
LONG nError = GetDWORDRegKey(hKey, strValueName.c_str(), nResult, nDefValue);
if (ERROR_SUCCESS == nError)
{
bValue = (nResult != 0) ? true : false;
}
return nError;
}
LONG GetStringRegKey(HKEY hKey, const std::wstring &strValueName, std::wstring &strValue, const std::wstring &strDefaultValue)
{
strValue = strDefaultValue;
WCHAR szBuffer[512];
DWORD dwBufferSize = sizeof(szBuffer);
ULONG nError;
nError = RegQueryValueExW(hKey, strValueName.c_str(), 0, NULL, (LPBYTE)szBuffer, &dwBufferSize);
if (ERROR_SUCCESS == nError)
{
strValue = szBuffer;
}
return nError;
}
After reading a bunch of people's comments online about this, my first reaction was that this is basically one of those really unimportant debates. However, my initial interest was to find out the right format so I could be consistent with my file naming practice.
Long story short, the creator of YAML are saying .yaml
, but personally I keep doing .yml
. That just makes more sense to me. So I went on the journey to find affirmation and soon enough, I realise that docker uses .yml
everywhere. I've been writing docker-compose.yml
files all this time, while you keep seeing in kubernetes' docs kubectl apply -f *.yaml
...
So, in conclusion, both formats are obviously accepted and if you are on the other end, (ie: writing systems that receive a YAML file as input) you should allow for both. That seems like another snake case versus camel case thingy...

I was also facing the same problem and I spent more than a week to fix it. Restarting my machine seemed to have fixed it, but only temporarily.
There was a solution to increase the maximum number of ephemeral ports by editing the registry file. That seemed to have fixed the problem but that also, only temporarily.
For sometime, I kept thinking if I was trying to access a driver which is no longer available, so I have tried to call:
driver.quit()
And then recreate the browser instance, which only gave me: SessionNotFoundException.
I now realized that I had used BOTH System.setProperty
as well as ffCapability.setCapability
to set the path of the binary.
I then tried with only System.setProperty
=> No luck there.
Only ffCapability.setCapability
=> Voila!!! So far it has been working fine. Hopefully it will work great when I try to re-run my scripts tomorrow and the day after and the day after... :)
Bottomline: Use only this
ffCapability.setCapability("binary", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"); //for windows`
Hope it helps!
If you don't have any data assigned already to you database do the following:
use Illuminate\Support\ServiceProvider;
and inside of the method boot();
Schema::defaultStringLength(191);
Now delete the records in your database, user table for ex.
run the following
php artisan config:cache
php artisan migrate
its because of Headerfiles define what the class contains (Members, data-structures) and cpp files implement it.
And of course, the main reason for this is that you could include one .h File multiple times in other .h files, but this would result in multiple definitions of a class, which is invalid.
Here's a take on using Kotlin Delegated Properties that I picked up from here, but expanded on and allows for a simple mechanism for getting/setting SharedPreference properties.
For String
, Int
, Long
, Float
or Boolean
, it uses the standard SharePreference getter(s) and setter(s). However, for all other data classes, it uses GSON to serialize to a String
, for the setter. Then deserializes to the data object, for the getter.
Similar to other solutions, this requires adding GSON as a dependency in your gradle file:
implementation 'com.google.code.gson:gson:2.8.6'
Here's an example of a simple data class that we would want to be able to save and store to SharedPreferences:
data class User(val first: String, val last: String)
Here is the one class that implements the property delegates:
object UserPreferenceProperty : PreferenceProperty<User>(
key = "USER_OBJECT",
defaultValue = User(first = "Jane", last = "Doe"),
clazz = User::class.java)
object NullableUserPreferenceProperty : NullablePreferenceProperty<User?, User>(
key = "NULLABLE_USER_OBJECT",
defaultValue = null,
clazz = User::class.java)
object FirstTimeUser : PreferenceProperty<Boolean>(
key = "FIRST_TIME_USER",
defaultValue = false,
clazz = Boolean::class.java
)
sealed class PreferenceProperty<T : Any>(key: String,
defaultValue: T,
clazz: Class<T>) : NullablePreferenceProperty<T, T>(key, defaultValue, clazz)
@Suppress("UNCHECKED_CAST")
sealed class NullablePreferenceProperty<T : Any?, U : Any>(private val key: String,
private val defaultValue: T,
private val clazz: Class<U>) : ReadWriteProperty<Any, T> {
override fun getValue(thisRef: Any, property: KProperty<*>): T = HandstandApplication.appContext().getPreferences()
.run {
when {
clazz.isAssignableFrom(String::class.java) -> getString(key, defaultValue as String?) as T
clazz.isAssignableFrom(Int::class.java) -> getInt(key, defaultValue as Int) as T
clazz.isAssignableFrom(Long::class.java) -> getLong(key, defaultValue as Long) as T
clazz.isAssignableFrom(Float::class.java) -> getFloat(key, defaultValue as Float) as T
clazz.isAssignableFrom(Boolean::class.java) -> getBoolean(key, defaultValue as Boolean) as T
else -> getObject(key, defaultValue, clazz)
}
}
override fun setValue(thisRef: Any, property: KProperty<*>, value: T) = HandstandApplication.appContext().getPreferences()
.edit()
.apply {
when {
clazz.isAssignableFrom(String::class.java) -> putString(key, value as String?) as T
clazz.isAssignableFrom(Int::class.java) -> putInt(key, value as Int) as T
clazz.isAssignableFrom(Long::class.java) -> putLong(key, value as Long) as T
clazz.isAssignableFrom(Float::class.java) -> putFloat(key, value as Float) as T
clazz.isAssignableFrom(Boolean::class.java) -> putBoolean(key, value as Boolean) as T
else -> putObject(key, value)
}
}
.apply()
private fun Context.getPreferences(): SharedPreferences = getSharedPreferences(APP_PREF_NAME, Context.MODE_PRIVATE)
private fun <T, U> SharedPreferences.getObject(key: String, defValue: T, clazz: Class<U>): T =
Gson().fromJson(getString(key, null), clazz) as T ?: defValue
private fun <T> SharedPreferences.Editor.putObject(key: String, value: T) = putString(key, Gson().toJson(value))
companion object {
private const val APP_PREF_NAME = "APP_PREF"
}
}
Note: you shouldn't need to update anything in the sealed class
. The delegated properties are the Object/Singletons UserPreferenceProperty
, NullableUserPreferenceProperty
and FirstTimeUser
.
To setup a new data object for saving/getting from SharedPreferences, it's now as easy as adding four lines:
object NewPreferenceProperty : PreferenceProperty<String>(
key = "NEW_PROPERTY",
defaultValue = "",
clazz = String::class.java)
Finally, you can read/write values to SharedPreferences by just using the by
keyword:
private var user: User by UserPreferenceProperty
private var nullableUser: User? by NullableUserPreferenceProperty
private var isFirstTimeUser: Boolean by
Log.d("TAG", user) // outputs the `defaultValue` for User the first time
user = User(first = "John", last = "Doe") // saves this User to the Shared Preferences
Log.d("TAG", user) // outputs the newly retrieved User (John Doe) from Shared Preferences
Use LINQ OrderByDescending
method. It returns IOrderedIEnumerable<int>
, which you can convert back to Array if you need so. Generally, List<>
s are more functional then Array
s.
array = array.OrderByDescending(c => c).ToArray();
I ended up doing this for macOS. I'm sure this is terrible in many ways:
#!/bin/sh
# watchAndRun
if [ $# -ne 2 ]; then
echo "Use like this:"
echo " $0 filename-to-watch command-to-run"
exit 1
fi
if which fswatch >/dev/null; then
echo "Watching $1 and will run $2"
while true; do fswatch --one-event $1 >/dev/null && $2; done
else
echo "You might need to run: brew install fswatch"
fi
Check out Refactoring Databases (http://databaserefactoring.com/) for a bunch of good techniques for maintaining your database in tandem with code changes.
Suffice to say that you're asking the wrong questions. Instead of putting your database into git you should be decomposing your changes into small verifiable steps so that you can migrate/rollback schema changes with ease.
If you want to have full recoverability you should consider archiving your postgres WAL logs and use the PITR (point in time recovery) to play back/forward transactions to specific known good states.
Add <!doctype html>
at the top of your HTML output.
You can add these single quotes with template literals:
var text = "http://example.com"_x000D_
var quoteText = `'${text}'`_x000D_
_x000D_
console.log(quoteText)
_x000D_
Docs are here. Browsers that support template literals listed here.
The errors you posted are unrelated. The first one is due to you selecting a backend that is not meant for interactive use, i.e. agg. You can still use (and should use) those for the generation of plots in scripts that don't require user interaction.
If you want an interactive lab-environment, as in Matlab/Pylab, you'd obviously import a backend supporting gui usage, such as Qt4Agg (needs Qt and AGG), GTKAgg (GTK an AGG) or WXAgg (wxWidgets and Agg).
I'd start by trying to use WXAgg, apart from that it really depends on how you installed Python and matplotlib (source, package etc.)
As far as I know, it can be done. Python has implicit line continuation (inside parentheses, brackets, and strings) for triple-quoted strings ("""like this"""
)and the indentation of continuation lines is not important. For more info, you may want to read this article on lexical analysis, from python.org.
You can also use the FileReader class :
var reader = new FileReader();
reader.onload = function (e) {
var data = this.result;
}
reader.readAsDataURL( file );
>>> print "%r, %r" % (True, False)
True, False
This is not specific to boolean values - %r
calls the __repr__
method on the argument. %s
(for str
) should also work.
tldr: flushdb
clears one database and flushall
clears all databases
Delete default or currently selected database (usually `0) with
redis-cli flushdb
Delete specific redis database with (e.g. 8
as my target database):
redis-cli -n 8 flushdb
Delete all redis databases with
redis-cli flushall
You need to initialize the list first:
protected List<string> list = new List<string>();
Highly recommend using a handler to handle the response.
client.execute(yourRequest,defaultHanler);
It will release the connection automatically with consume(HTTPENTITY)
method.
A handler example:
private ResponseHandler<String> defaultHandler = new ResponseHandler<String>() {
@Override
public String handleResponse(HttpResponse response)
throws IOException {
int status = response.getStatusLine().getStatusCode();
if (status >= 200 && status < 300) {
HttpEntity entity = response.getEntity();
return entity != null ? EntityUtils.toString(entity) : null;
} else {
throw new ClientProtocolException("Unexpected response status: " + status);
}
}
};
If the file does not exists, open(name,'r+')
will fail.
You can use open(name, 'w')
, which creates the file if the file does not exist, but it will truncate the existing file.
Alternatively, you can use open(name, 'a')
; this will create the file if the file does not exist, but will not truncate the existing file.
In my IE11, works normally. Version: 11.306.10586.0

See this table.
A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.
A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.
if you use external libraries in your program and you try to pack all together in a jar file it's not that simple, because of classpath issues etc.
I'd prefer to use OneJar for this issue.
For me none of earlier answer works. I did need to convert my static class to enum. Like this:
export enum MyConstants {
MyFirstConstant = 'MyFirstConstant',
MySecondConstant = 'MySecondConstant'
}
Then in my component I add new property as suggested in other answers
export class MyComponent {
public MY_CONTANTS = MyConstans;
constructor() { }
}
Then in my component's template I use it this way
<div [myDirective]="MY_CONTANTS.MyFirstConstant"> </div>
EDIT: Sorry. My problem was different than OP's. I still leave this here if someelse have same problem than I.
What's the difference?
/[a-zA-Z0-9]/
is a character class which matches one character that is inside the class. It consists of three ranges.
/a-zA-Z0-9/
does mean the literal sequence of those 9 characters.
Which chars from
.!@#$%^&*()_+-=
are needed to be escaped?
Inside a character class, only the minus (if not at the end) and the circumflex (if at the beginning). Outside of a charclass, .$^*+()
have a special meaning and need to be escaped to match literally.
allows only the
a-zA-Z0-9
characters and.!@#$%^&*()_+-=
Put them in a character class then, let them repeat and require to match the whole string with them by anchors:
var regex = /^[a-zA-Z0-9!@#$%\^&*)(+=._-]*$/
I strongly recommend using lowercase field|column names, it will make your life easier.
Let's assume you have a table called users with the following definition and records:
id|firstname|lastname|username |password
1 |joe |doe |[email protected] |1234
2 |jane |doe |[email protected] |12345
3 |johnny |doe |[email protected]|123456
let's say you want to get all records from table users, then you do:
SELECT * FROM users;
Now let's assume you want to select all records from table users, but you're interested only in the fields id, firstname and lastname, thus ignoring username and password:
SELECT id, firstname, lastname FROM users;
Now we get at the point where you want to retrieve records based on condition(s), what you need to do is to add the WHERE clause, let's say we want to select from users only those that have username = [email protected] and password = 1234, what you do is:
SELECT * FROM users
WHERE ( ( username = '[email protected]' ) AND ( password = '1234' ) );
But what if you need only the id of a record with username = [email protected] and password = 1234? then you do:
SELECT id FROM users
WHERE ( ( username = '[email protected]' ) AND ( password = '1234' ) );
Now to get to your question, as others before me answered you can use the IN clause:
SELECT * FROM users
WHERE ( id IN (1,2,..,n) );
or, if you wish to limit to a list of records between id 20 and id 40, then you can easily write:
SELECT * FROM users
WHERE ( ( id >= 20 ) AND ( id <= 40 ) );
I hope this gives a better understanding.
var dir = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
I jumped in for the top rated answer and found myself not getting what I expected. I had to read the comments to find what I was looking for.
For that reason I am posting the answer listed in the comments to give it the exposure it deserves.
DAO (Data Access Object) is a very used design pattern in enterprise applications. It basically is the module that is used to access data from every source (DBMS, XML and so on). I suggest you to read some examples, like this one:
Please note that there are different ways to implements the original DAO Pattern, and there are many frameworks that can simplify your work. For example, the ORM (Object Relational Mapping) frameworks like iBatis or Hibernate, are used to map the result of SQL queries to java objects.
Hope it helps, Bye!
Expanding on what others have said I will give a short example.
If you have a 1D array ...
>>> import numpy as np
>>> x = np.arange(4) # array([0, 1, 2, 3])
>>> x[::-1] # returns a view
Out[1]:
array([3, 2, 1, 0])
But if you are working with a 2D array ...
>>> x = np.arange(10).reshape(2, 5)
>>> x
Out[2]:
array([[0, 1, 2, 3, 4],
[5, 6, 7, 8, 9]])
>>> x[::-1] # returns a view:
Out[3]: array([[5, 6, 7, 8, 9],
[0, 1, 2, 3, 4]])
This does not actually reverse the Matrix.
Should use np.flip to actually reverse the elements
>>> np.flip(x)
Out[4]: array([[9, 8, 7, 6, 5],
[4, 3, 2, 1, 0]])
If you want to print the elements of a matrix one-by-one use flat along with flip
>>> for el in np.flip(x).flat:
>>> print(el, end = ' ')
9 8 7 6 5 4 3 2 1 0
I had today a similar error message. What was peculiar is that it did not break the Application. It was running smoothly but the command prompt (Windows machine) indicated there was an error. I did not update the Typescript version but found another culprit. It turned there was a tiny omission of symbol - closing ")", which I believe The Typescript is compensating for. Just for reference the code is the following:
[new Object('First Characteristic','Second Characteristic',
'Third Characteristic'*]
* notice here the ending ")" is missing.
Once brought back no more issues on the command prompt!
For anyone who may stumble across this old question ...
There is one thing that I think needs to be addressed.
~/.nanorc
is used to apply your user specific settings to nano, so if you are editing files that require the use of sudo nano
for permissions then this is not going to work.
When using sudo
your custom user configuration files will not be loaded when opening a program, as you are not running the program from your account so none of your configuration changes in ~/.nanorc
will be applied.
If this is the situation you find yourself in (wanting to run sudo nano
and use your own config settings) then you have three options :
sudo nano
/root/.nanorc
file/etc/nanorc
global config fileKeep in mind that /etc/nanorc
is a global configuration file and as such it affects all users, which may or may not be a problem depending on whether you have a multi-user system.
Also, user config files will override the global one, so if you were to edit /etc/nanorc
and ~/.nanorc
with different settings, when you run nano
it will load the settings from ~/.nanorc
but if you run sudo nano
then it will load the settings from /etc/nanorc
.
Same goes for /root/.nanorc
this will override /etc/nanorc
when running sudo nano
Using flags is probably the best option unless you have a lot of options.
This Perl one-liner shows how closely Perl is related to awk:
perl -lane 'print $F[3]' text.txt
However, the @F
autosplit array starts at index $F[0]
while awk fields start with $1
What you are looking to do is get the position using the LocationManager.NETWORK_PROVIDER
instead of LocationManager.GPS_PROVIDER
. The NETWORK_PROVIDER
will resolve on the GSM or wifi, which ever available. Obviously with wifi off, GSM will be used. Keep in mind that using the cell network is accurate to basically 500m.
http://developer.android.com/guide/topics/location/obtaining-user-location.html has some really great information and sample code.
After you get done with most of the code in OnCreate()
, add this:
// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
makeUseOfNewLocation(location);
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
You could also have your activity implement the LocationListener
class and thus implement onLocationChanged()
in your activity.
The simple jquery source for the same -
$("input:radio[name='group1']").click(function() {
$('.desc').hide();
$('#' + $("input:radio[name='group1']:checked").val()).show();
});
In order to make it little more appropriate just add checked to first option --
<div><label><input type="radio" name="group1" value="opt1" checked>opt1</label></div>
remove .desc class from styling and modify divs like --
<div id="opt1" class="desc">lorem ipsum dolor</div>
<div id="opt2" class="desc" style="display: none;">consectetur adipisicing</div>
<div id="opt3" class="desc" style="display: none;">sed do eiusmod tempor</div>
it will really look good any-ways.
Use JodaTime for this. It is much better than the standard Java DateTime Apis. Here is the code in JodaTime for calculating difference in days:
private static void dateDiff() {
System.out.println("Calculate difference between two dates");
System.out.println("=================================================================");
DateTime startDate = new DateTime(2000, 1, 19, 0, 0, 0, 0);
DateTime endDate = new DateTime();
Days d = Days.daysBetween(startDate, endDate);
int days = d.getDays();
System.out.println(" Difference between " + endDate);
System.out.println(" and " + startDate + " is " + days + " days.");
}
I think Octave only return one value which is the first return value, in your case, 'array'.
And Octave print it as "ans".
Others, 'listp','freep' were not printed.
Because it showed up within the function.
Try this out:
[ A, B, C] = initialize( 4 )
And the 'array','listp','freep' will print as A, B and C.
Without Installing python-docx
docx
is basically is a zip file with several folders and files within it. In the link below you can find a simple function to extract the text from docx
file, without the need to rely on python-docx
and lxml
the latter being sometimes hard to install:
http://etienned.github.io/posts/extract-text-from-word-docx-simply/
Talking about efficiency:
document.getElementById( 'elemtId' ).style.display = 'none';
What jQuery does with its .show()
and .hide()
methods is, that it remembers the last state of an element. That can come in handy sometimes, but since you asked about efficiency that doesn't matter here.
Very old question, but still wanted to add this.
If you're looking for a one-liner, you can use the code below. It combines the list constructor that accepts an enumerable and the "new" (since question raised) initializer syntax.
myArray = new List<string>(myArray) { "add this" }.ToArray();
Not sure if you want jQuery.
var form;
form.onsubmit = function (e) {
// stop the regular form submission
e.preventDefault();
// collect the form data while iterating over the inputs
var data = {};
for (var i = 0, ii = form.length; i < ii; ++i) {
var input = form[i];
if (input.name) {
data[input.name] = input.value;
}
}
// construct an HTTP request
var xhr = new XMLHttpRequest();
xhr.open(form.method, form.action, true);
xhr.setRequestHeader('Content-Type', 'application/json; charset=UTF-8');
// send the collected data as JSON
xhr.send(JSON.stringify(data));
xhr.onloadend = function () {
// done
};
};
The problem occurred due to the Control validator. Just Add the J Query reference to your web page as follows and then add the Validation Settings in your web.config file to overcome the problem. I too faced the same problem and the below gave the solution to my problem.

Step2 :
It will resolve your problem.
If Table variable has large data, then instead of table variable(@table) create temp table (#table).table variable doesn't allow to create index after insert.
CREATE TABLE #Table(C1 int,
C2 NVarchar(100) , C3 varchar(100)
UNIQUE CLUSTERED (c1)
);
Create table with unique clustered index
Insert data into Temp "#Table" table
Create non clustered indexes.
CREATE NONCLUSTERED INDEX IX1 ON #Table (C2,C3);
You can add other repo first as a remote to your current repo:
git remote add other_name PATH_TO_OTHER_REPO
then fetch brach from that remote:
git fetch other_name branch_name:branch_name
this creates that branch as a new branch in your current repo, then you can diff that branch with any of your branches, for example, to compare current branch against new branch(branch_name):
git diff branch_name
In this specific example, where the DataFrame is only one column, you can write this elegantly as:
df['desired_output'] = df.le(2.5)
le
tests whether elements are less than or equal 2.5, similarly lt
for less than, gt
and ge

- subnet: 172.20.0.0/16
#docker-compose v3+ do not use ip_range
ip_range: 172.28.5.0/24
from host you can test using:
docker-compose up -d
curl 172.20.128.2
Modern docker-compose
does not change ip address that frequently.
To find ips of all containers in your docker-compose
in a single line use:
for s in `docker-compose ps -q`; do echo ip of `docker inspect -f "{{.Name}}" $s` is `docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $s`; done
If you want to automate, you can use something like this example gist

This answer concerns developers for Windows. You want to pick an XML parsing module that does NOT depend on node-expat. Node-expat requires node-gyp and node-gyp requires you to install Visual Studio on your machine. If your machine is a Windows Server, you definitely don't want to install Visual Studio on it.
So, which XML parsing module to pick?
Save yourself a lot of trouble and use either xml2js or xmldoc. They depend on sax.js which is a pure Javascript solution that doesn't require node-gyp.
Both libxmljs and xml-stream require node-gyp. Don't pick these unless you already have Visual Studio on your machine installed or you don't mind going down that road.
Update 2015-10-24: it seems somebody found a solution to use node-gyp on Windows without installing VS: https://github.com/nodejs/node-gyp/issues/629#issuecomment-138276692
Hashtables are not inherently sorted, your best bet is to use another structure such as a SortedList or an ArrayList
What you have should work. It depends on the type of data you are setting i.e. if it's a string value you need to make sure it's in quotes e.g.
var val = '@ViewBag.ForSection';
If it's an integer you need to parse it as one i.e.
var val = parseInt(@ViewBag.ForSection);
This usually happens when the repo contains some items that are not there locally. So in order to push our changes, in this case we need to integrate the remote changes and then push.
So create a pull from remote
git pull origin master
Then push changes to that remote
git push origin master

There are ways to handle your own signals in certain JVMs -- see this article about the HotSpot JVM for example.
By using the Sun internal sun.misc.Signal.handle(Signal, SignalHandler)
method call you are also able to register a signal handler, but probably not for signals like INT
or TERM
as they are used by the JVM.
To be able to handle any signal you would have to jump out of the JVM and into Operating System territory.
What I generally do to (for instance) detect abnormal termination is to launch my JVM inside a Perl script, but have the script wait for the JVM using the waitpid
system call.
I am then informed whenever the JVM exits, and why it exited, and can take the necessary action.
The trick to triggering an asynchronous stylesheet download is to use a <link>
element and set an invalid value for the media attribute (I'm using media="none", but any value will do). When a media query evaluates to false, the browser will still download the stylesheet, but it won't wait for the content to be available before rendering the page.
<link rel="stylesheet" href="css.css" media="none">
Once the stylesheet has finished downloading the media attribute must be set to a valid value so the style rules will be applied to the document. The onload event is used to switch the media property to all:
<link rel="stylesheet" href="css.css" media="none" onload="if(media!='all')media='all'">
This method of loading CSS will deliver useable content to visitors much quicker than the standard approach. Critical CSS can still be served with the usual blocking approach (or you can inline it for ultimate performance) and non-critical styles can be progressively downloaded and applied later in the parsing / rendering process.
This technique uses JavaScript, but you can cater for non-JavaScript browsers by wrapping the equivalent blocking <link>
elements in a <noscript>
element:
<link rel="stylesheet" href="css.css" media="none" onload="if(media!='all')media='all'"><noscript><link rel="stylesheet" href="css.css"></noscript>

find()
takes a selector, not a value. This means you need to use it in the same way you would use the regular jQuery function ($('selector')
).
Therefore you need to do something like this:
$(this).find('[value="X"]').remove();
See the jQuery find docs.
After reading so many articles, Stack Overflow posts and making demo applications to check variable property attributes, I decided to put all the attributes information together:
atomic
// Defaultnonatomic
strong = retain
// Defaultweak = unsafe_unretained
retain
assign
// Defaultunsafe_unretained
copy
readonly
readwrite
// DefaultIn the article Variable property attributes or modifiers in iOS you can find all the above-mentioned attributes, and that will definitely help you.
atomic
atomic
means only one thread access the variable (static type).atomic
is thread safe.atomic
is the default behaviorExample:
@property (retain) NSString *name;
@synthesize name;
nonatomic
nonatomic
means multiple thread access the variable (dynamic type).nonatomic
is thread-unsafe.nonatomic
is NOT default behavior. We need to add the nonatomic
keyword in the property attribute.Example:
@property (nonatomic, retain) NSString *name;
@synthesize name;
Use a data list instead.

For random hash values, some engineers said golden ratio prime number(2654435761) is a bad choice, with my testing results, I found that it's not true; instead, 2654435761 distributes the hash values pretty good.
#define MCR_HashTableSize 2^10
unsigned int
Hash_UInt_GRPrimeNumber(unsigned int key)
{
key = key*2654435761 & (MCR_HashTableSize - 1)
return key;
}
The hash table size must be a power of two.
I have written a test program to evaluate many hash functions for integers, the results show that GRPrimeNumber is a pretty good choice.
I have tried:
With my testing results, I found that Golden Ratio Prime Number always has the fewer empty buckets or zero empty bucket and the shortest collision chain length.
Some hash functions for integers are claimed to be good, but the testing results show that when the total_data_entry / total_bucket_number = 3, the longest chain length is bigger than 10(max collision number > 10), and many buckets are not mapped(empty buckets), which is very bad, compared with the result of zero empty bucket and longest chain length 3 by Golden Ratio Prime Number Hashing.
BTW, with my testing results, I found one version of shifting-xor hash functions is pretty good(It's shared by mikera).

key ^= (key << 13);
key ^= (key >> 17);
key ^= (key << 5);

Assuming getItemNumber()
returns an int
, replace
if (id.equals(list[pos].getItemNumber()))
with
if (id == list[pos].getItemNumber())
Let's take the example of an NSError
, if there isn't an error being returned you'd want to make it optional to return Nil. There's no point in assigning a value to it if there isn't an error..
var error: NSError? = nil
This also allows you to have a default value. So you can set a method a default value if the function isn't passed anything
func doesntEnterNumber(x: Int? = 5) -> Bool {
if (x == 5){
return true
} else {
return false
}

If you have Bluetooth, Use twedge on windows and getblue app on android, they also have a few videos of it. It's made by TEC-IT. I've got it to work by setting the interface option to bluetooth server in TWedge and setting the output setting in getblue to Bluetooth client and selecting my computer from the Bluetooth devices list. Make sure your computer and phone is paired. Also to get the barcode as input set the action setting in TWedge to Keyboard Wedge. This will allow for you to first click the input text box on said form, then scan said product with your phone and wait a sec for the barcode number to be put into the text box. Using this method requires no php that doesn't already exist in your current form processing, just process the text box as usual and viola your phone scans bar codes, sends them to your pc via Bluetooth wirelessly, your computer inserts the barcode into whatever text field is selected in any application or website. Hope this helps.
I had this same issue, and there's a really quick and simple solution without CSS of JS. Just create a separate unstyled div with an ID like "aboutMeAnchor
and just place it well above the section you actually want to land on.
In case you want to clone a specific branch only, then,
git clone -b <branch-name> <repo-url> <destination-folder-name>

select a.ip, a.os, a.hostname, a.port, a.protocol,
b.state
from a
left join b on a.ip = b.ip
and a.port = b.port

Sometimes it is just how you export and import it. For this error message it could be, that the default keyword is missing.
export default SampleClass {}
Where you instantiate it:
import SampleClass from 'path/to/class';
let sampleClass = new SampleClass();
Option 2, with curly braces:
export SampleClass {}
import { SampleClass } from 'path/to/class';
let sampleClass = new SampleClass();

As of Angular 6+, this is handled slightly differently than in previous versions. As @BeetleJuice mentions in the answer above, paramMap
is new interface for getting route params, but the execution is a bit different in more recent versions of Angular. Assuming this is in a component:
private _entityId: number;
constructor(private _route: ActivatedRoute) {
// ...
}
ngOnInit() {
// For a static snapshot of the route...
this._entityId = this._route.snapshot.paramMap.get('id');
// For subscribing to the observable paramMap...
this._route.paramMap.pipe(
switchMap((params: ParamMap) => this._entityId = params.get('id'))
);
// Or as an alternative, with slightly different execution...
this._route.paramMap.subscribe((params: ParamMap) => {
this._entityId = params.get('id');
});
}
I prefer to use both because then on direct page load I can get the ID param, and also if navigating between related entities the subscription will update properly.
If portability is important you may not want to depend on a specific shell in your Makefile. Not all environments have bash available.
Here is the locale grouping code after removing irrelevant parts and cleaning it up a little:
(The following only works for integers)
def group(number):
s = '%d' % number
groups = []
while s and s[-1].isdigit():
groups.append(s[-3:])
s = s[:-3]
return s + ','.join(reversed(groups))
>>> group(-23432432434.34)
'-23,432,432,434'
There are already some good answers in here. I just want to add this for future reference. In python 2.7 there is going to be a format specifier for thousands separator. According to python docs it works like this
>>> '{:20,.2f}'.format(f)
'18,446,744,073,709,551,616.00'
In python3.1 you can do the same thing like this:
>>> format(1234567, ',d')
'1,234,567'
Overall
SELECT
COUNT(DISTINCT `site_id`) as distinct_sites
FROM `cp_visits`
WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
Or per site
SELECT
`site_id` as site,
COUNT(DISTINCT `user_id`) as distinct_users_per_site
FROM `cp_visits`
WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
GROUP BY `site_id`
Having the time
column in the result doesn't make sense - since you are aggregating the rows, showing one particular time
is irrelevant, unless it is the min
or max
you are after.
Just discovered this:
SELECT * FROM OPENROWSET(BULK N'<PATH_TO_FILE>', SINGLE_CLOB) AS Contents
It'll pull in the contents of the file as varchar(max). Replace SINGLE_CLOB

for nvarchar(max)
SINGLE_BLOB
for varbinary(max)

For those of you that prefer a more concise, easier to read lambda coding style...
This example removes all non-alphanumeric and white space characters from a wide string. You can mix it up with any of the other ctype.h helper functions to remove complex-looking character-based tests.
(I'm not sure how these functions would handle CJK languages, so walk softly there.)
// Boring C loops: 'for(int i=0;i<str.size();i++)'
// Boring C++ eqivalent: 'for(iterator iter=c.begin; iter != c.end; ++iter)'
See if you don't find this easier to understand than noisy C/C++ for/iterator loops:
TSTRING label = _T("1. Replen & Move RPMV");
TSTRING newLabel = label;
set<TCHAR> badChars; // Use ispunct, isalpha, isdigit, et.al. (lambda version, with capture list parameter(s) example; handiest thing since sliced bread)
for_each(label.begin(), label.end(), [&badChars](TCHAR n){
if (!isalpha(n) && !isdigit(n))
badChars.insert(n);
});
for_each(badChars.begin(), badChars.end(), [&newLabel](TCHAR n){
newLabel.erase(std::remove(newLabel.begin(), newLabel.end(), n), newLabel.end());
});
newLabel results after running this code: "1ReplenMoveRPMV"
This is just academic, since it would clearly be more precise, concise and efficient to combine the 'if' logic from lambda0 (first for_each) into the single lambda1 (second for_each), if you have already established which characters are the "badChars".
And to complement Rich's recursive answer, a non-recursive method.
Public Sub NonRecursiveMethod()
Dim fso, oFolder, oSubfolder, oFile, queue As Collection
Set fso = CreateObject("Scripting.FileSystemObject")
Set queue = New Collection
queue.Add fso.GetFolder("your folder path variable") 'obviously replace
Do While queue.Count > 0
Set oFolder = queue(1)
queue.Remove 1 'dequeue
'...insert any folder processing code here...
For Each oSubfolder In oFolder.SubFolders
queue.Add oSubfolder 'enqueue
Next oSubfolder
For Each oFile In oFolder.Files
'...insert any file processing code here...
Next oFile
Loop
End Sub
You can use a queue for FIFO behaviour (shown above), or you can use a stack for LIFO behaviour which would process in the same order as a recursive approach (replace Set oFolder = queue(1)
with Set oFolder = queue(queue.Count)
and replace queue.Remove(1)
with queue.Remove(queue.Count)
, and probably rename the variable...)
A simple alternative is to use numpy's concatenate but it converts the contents to float:
import numpy as np
print np.concatenate([[1,2],[3],[5,89],[],[6]])
# array([ 1., 2., 3., 5., 89., 6.])
print list(np.concatenate([[1,2],[3],[5,89],[],[6]]))
# [ 1., 2., 3., 5., 89., 6.]
POD is the official way to do multi line comments in Perl,
From faq.perl.org[perlfaq7]
The quick-and-dirty way to comment out more than one line of Perl is to surround those lines with Pod directives. You have to put these directives at the beginning of the line and somewhere where Perl expects a new statement (so not in the middle of statements like the # comments). You end the comment with
=cut
, ending the Pod section:
=pod
my $object = NotGonnaHappen->new();
ignored_sub();
$wont_be_assigned = 37;
=cut
The quick-and-dirty method only works well when you don't plan to leave the commented code in the source. If a Pod parser comes along, your multiline comment is going to show up in the Pod translation. A better way hides it from Pod parsers as well.
The
=begin
directive can mark a section for a particular purpose. If the Pod parser doesn't want to handle it, it just ignores it. Label the comments withcomment
. End the comment using=end
with the same label. You still need the=cut
to go back to Perl code from the Pod comment:
=begin comment
my $object = NotGonnaHappen->new();
ignored_sub();
$wont_be_assigned = 37;
=end comment
=cut
How about a solution where you put the actual "data" of the table inside its own div, with overflow: scroll;
? Then the browser will automatically create scrollbars for the portion of the "table" you do not want to lock, and you can put the "table header"/first row just above that <div>
.
Not sure how that would work with scrolling horizontally though.
I know this is old, but wanted to share my solution.
In my case the issue was in my .htaccess as I added variables to raise my PHP's max upload limit. My code was like this:
php_value post_max_size 50MB
php_value upload_max_filesize 50MB
Later I notice that the values should like xxM not xxMB and when I changed it to:
php_value post_max_size 50M
php_value upload_max_filesize 50M
now my $_POST returned the data as normal before. Hope this helps someone in the future.
You can use os.sep:
>>> import os
>>> os.sep
'/'
I came up with the following algorithm.
My idea: go through all the whole file of integers once and for every bit position count its 0s and 1s. The amount of 0s and 1s must be 2^(numOfBits)/2, therefore, if the amount is less then expected we can use it of our resulting number.
For example, suppose integer is 32 bit, then we require
int[] ones = new int[32];
int[] zeroes = new int[32];
For every number we have to iterate though 32 bits and increase value of 0 or 1:
for(int i = 0; i < 32; i++){
ones[i] += (val>>i&0x1);
zeroes[i] += (val>>i&0x1)==1?0:1;
}
Finally, after the file was processed:
int res = 0;
for(int i = 0; i < 32; i++){
if(ones[i] < (long)1<<31)res|=1<<i;
}
return res;
NOTE: in some languages (ex. Java) 1<<31 is a negative number, therefore, (long)1<<31 is the right way to do it
The comment by jsz above saved me tons of pain, so here's a step-by-step recipie based on it that I've been using to rebase/move any commit on top of any other commit:
git rebase --onto <new parent> <old parent>
In the example above that's as simple as:
git checkout topic
git rebase --onto B A
For me, the following hack worked; Go to IIS -> Application Pools -> Advance Settings -> Process Model -> Identity Changed from Built-in Account (ApplicationPoolIdentity) to Custom Account (My Domain User)
I always thought that for a task that trivial, I wouldn't want to import anything. But i may be wrong, depending on collections.Counter being faster or not.
items = "Whats the simpliest way to add the list items to a dictionary "
stats = {}
for i in items:
if i in stats:
stats[i] += 1
else:
stats[i] = 1
# bonus
for i in sorted(stats, key=stats.get):
print("%d×'%s'" % (stats[i], i))
I think this may be preferable to using count(), because it will only go over the iterable once, whereas count may search the entire thing on every iteration. I used this method to parse many megabytes of statistical data and it always was reasonably fast.
Simple and with little changes. And also hide load more when entire list is loaded.

By HTML specifications, browsers are required to canonicalize line breaks in user input to CR LF (\r\n
), and I don’t think any browser gets this wrong. Reference: clause 17.13.4 Form content types in the HTML 4.01 spec.
In HTML5 drafts, the situation is more complicated, since they also deal with the processes inside a browser, not just the data that gets sent to a server-side form handler when the form is submitted. According to them (and browser practice), the textarea
element value exists in three variants:
I've edited Alix Axel's answer to take a third argrument, when setting this third argrument to true
all the files will be added under the main directory rather than directly in the zip folder.
If the zip file exists the file will be deleted as well.
Example:
Zip('/path/to/maindirectory','/path/to/compressed.zip',true);
Third argrument true
zip structure:
maindirectory
--- file 1
--- file 2
--- subdirectory 1
------ file 3
------ file 4
--- subdirectory 2
------ file 5
------ file 6

Variables in Javascript don't have a type. Non-zero, non-null, non-empty and true
are "true". Zero, null, undefined, empty string and false
are "false".
There's a Boolean type though, as are literals true

In classic mode IIS works h ISAPI extensions and ISAPI filters directly. And uses two pipe lines , one for native code and other for managed code. You can simply say that in Classic mode IIS 7.x works just as IIS 6 and you dont get extra benefits out of IIS 7.x features.
In integrated mode IIS and ASP.Net are tightly coupled rather then depending on just two DLLs on Asp.net as in case of classic mode.
This seems simpler to me
<li *ngFor="let item of list | slice:0:10; let i=index" class="dropdown-item" (click)="onClick(item)">{{item.text}}</li>
Closer to your approach
<ng-container *ngFor="let item of list" let-i="index">
<li class="dropdown-item" (click)="onClick(item)" *ngIf="i<11">{{item.text}}</li>
</ng-container>
Here my working code:
function IsJsonString(str) {
try {
var json = JSON.parse(str);
return (typeof json === 'object');
} catch (e) {
return false;
}
}
You maybe want to know what is not CGI, and the answer is a MODULE for your web server (if I suppose you are runnig Apache). AND THAT'S THE BIG DIFERENCE, because CGI needs and external program, thread, whatever to instantiate a PERL, PHP, C app server where when you run as a MODULE that program is the web server (apache) per-se.
Because of all this there is a lot of performance, security, portability issues that come into play. But it's good to know what is not CGI first, to understand what it is.
The values printed by your second program are seconds, and microseconds.
0 26339 = 0.026'339 s = 26339 µs
4 45025 = 4.045'025 s = 4045025 µs
A good gotcha is any error code > 255 will be converted to error code % 256. One should be specifically careful about this if they are using a custom error code > 255 and expecting the exact error code in the application logic. http://www.tldp.org/LDP/abs/html/exitcodes.html
you can use the in built .toLowerCase() method on javascript strings. ex: var x = "Hello"; x.toLowerCase();
No, it's doesn't give you a single executable in the sense that you only have one file afterwards - but you have a directory which contains everything you need for running your program, including an exe file.
I just wrote this setup.py today. You only need to invoke python setup.py py2exe
.
I would use IEnumerable<object>
as type for the argument. However not a great gain for the unavoidable explicit cast.
Cheers
It isn't an environment variable, but still gives you control over the temp dir:
-Djava.io.tmpdir
ex.:
java -Djava.io.tmpdir=/mytempdir
There are two obvious points, as well as the points in the other answer:
They are exactly equivalent when using sub queries:
SELECT * FROM table
WHERE column IN(subquery);
SELECT * FROM table
WHERE column = ANY(subquery);
On the other hand:
Only the IN
operator allows a simple list:
SELECT * FROM table
WHERE column IN(… , … , …);
Presuming they are exactly the same has caught me out several times when forgetting that ANY
doesn’t work with lists.
2 methods,
help()
inspect
1) inspect:
use inpsect module to explore code you want... NOTE: you can able to explore code only for modules (aka) packages you have imported
for eg:
>>> import randint
>>> from inspect import getsource
>>> getsource(randint) # here i am going to explore code for package called `randint`
2) help():
you can simply use help()
command to get help about builtin functions as well its code.
for eg:
if you want to see the code for str() , simply type - help(str)
it will return like this,
>>> help(str)
Help on class str in module __builtin__:
class str(basestring)
| str(object='') -> string
|
| Return a nice string representation of the object.
| If the argument is a string, the return value is the same object.
|
| Method resolution order:
| str
| basestring
| object
|
| Methods defined here:
|
| __add__(...)
| x.__add__(y) <==> x+y
|
| __contains__(...)
| x.__contains__(y) <==> y in x
|
| __eq__(...)
| x.__eq__(y) <==> x==y
|
| __format__(...)
| S.__format__(format_spec) -> string
|
| Return a formatted version of S as described by format_spec.
|
| __ge__(...)
| x.__ge__(y) <==> x>=y
|
| __getattribute__(...)

Here is the optimized code snippet to remove empty arrays/objects as well:
function removeNullsInObject(obj) {
if( typeof obj === 'string' ){ return; }
$.each(obj, function(key, value){
if (value === "" || value === null){
delete obj[key];
} else if ($.isArray(value)) {
if( value.length === 0 ){ delete obj[key]; return; }
$.each(value, function (k,v) {
removeNullsInObject(v);
});
} else if (typeof value === 'object') {
if( Object.keys(value).length === 0 ){
delete obj[key]; return;
}
removeNullsInObject(value);
}
});
}
Thanks @Alexis king :)
With the Dynamic Array formulas(as of this posting only available to Office 365 Insiders):
=COUNTA(UNIQUE(A:A))
str.erase(str.begin() + str.size() - 1)
str.erase(str.rbegin())
does not compile unfortunately, since reverse_iterator
cannot be converted to a normal_iterator.
C++11 is your friend in this case.
Several things here.
First off, you're defining your CSS in 3 places!
In line, in the head and externally. I suggest you only choose one. I'm going to suggest externally.
I suggest you update your code in your ASP form from
<td style="background-color: #A3A3A3; color: #FFFFFF; font-family: 'Arial Black'; font-size: large; font-weight: bold;"
class="style6">
to this:
<td class="style6">
And then update your css too
.style6
{
height: 79px; background-color: #A3A3A3; color: #FFFFFF; font-family: 'Arial Black'; font-size: large; font-weight: bold;
}
This removes the inline.
Now, to move it from the head of the webForm.
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>

</table>
</form>
</body>
</html>
Now, in a new file called master.css (in your css folder) add
ul {
list-style-type:none;
margin:0;
padding:0;
}
li {
display:inline;
padding:20px;
}
.style1
{
width: 100%;
}
.style2
{
height: 459px;
}
.style3
{
width: 100%;
height: 100%;
}
.style6
{
height: 79px; background-color: #A3A3A3; color: #FFFFFF; font-family: 'Arial Black'; font-size: large; font-weight: bold;
}
.style7
{
width: 345px;
height: 73px;

i had created new repo in github and i had the same problem, but it also had problem while pulling, so this worked for me.
but this is not advised in repos that already have many codes as this could mess up everything
git push origin master --force
Use robocopy
. Robocopy is shipped by default on Windows Vista and newer, and is considered the replacement for xcopy
. (xcopy
has some significant limitations, including the fact that it can't handle paths longer than 256 characters, even if the filesystem can).
robocopy c:\ d:\ /e /zb /copyall /purge /dcopy:dat
Note that using /purge
on the root directory of the volume will cause Robocopy to apply the requested operation on files inside the System Volume Information directory. Run robocopy /?
for help. Also note that you probably want to open the command prompt as an administrator to be able to copy system files. To speed things up, use /b
instead of /zb
.
I have just made a plugin for jQuery that allows easier keypress
events. Instead of having to find the number and put it in, all you have to do is this:
$(document).keydown(function(e) {
if (getPressedKey(e) == theKeyYouWantToFireAPressEventFor /*Add 'e.ctrlKey here to only fire if the combo is CTRL+theKeyYouWantToFireAPressEventFor'*/) {
// Your Code To Fire When You Press theKeyYouWantToFireAPressEventFor
}
});
It's that simple. Please note that theKeyYouWantToFireAPressEventFor
is not a number, but a string (e.g "a"
to fire when A is pressed, "ctrl"
to fire when CTRL (control) is pressed, or, in the case of a number, just 1
, no quotes. That would fire when 1 is pressed.)
function getPressedKey(e){var a,s=e.keyCode||e.which,c=65,r=66,o=67,l=68,t=69,f=70,n=71,d=72,i=73,p=74,u=75,h=76,m=77,w=78,k=79,g=80,b=81,v=82,q=83,y=84,j=85,x=86,z=87,C=88,K=89,P=90,A=32,B=17,D=8,E=13,F=16,G=18,H=19,I=20,J=27,L=33,M=34,N=35,O=36,Q=37,R=38,S=40,T=45,U=46,V=91,W=92,X=93,Y=48,Z=49,$=50,_=51,ea=52,aa=53,sa=54,ca=55,ra=56,oa=57,la=96,ta=97,fa=98,na=99,da=100,ia=101,pa=102,ua=103,ha=104,ma=105,wa=106,ka=107,ga=109,ba=110,va=111,qa=112,ya=113,ja=114,xa=115,za=116,Ca=117,Ka=118,Pa=119,Aa=120,Ba=121,Da=122,Ea=123,Fa=114,Ga=145,Ha=186,Ia=187,Ja=188,La=189,Ma=190,Na=191,Oa=192,Qa=219,Ra=220,Sa=221,Ta=222;return s==Fa&&(a="numlock"),s==Ga&&(a="scrolllock"),s==Ha&&(a="semicolon"),s==Ia&&(a="equals"),s==Ja&&(a="comma"),s==La&&(a="dash"),s==Ma&&(a="period"),s==Na&&(a="slash"),s==Oa&&(a="grave"),s==Qa&&(a="openbracket"),s==Ra&&(a="backslash"),s==Sa&&(a="closebracket"),s==Ta&&(a="singlequote"),s==B&&(a="ctrl"),s==D&&(a="backspace"),s==E&&(a="enter"),s==F&&(a="shift"),s==G&&(a="alt"),s==H&&(a="pause"),s==I&&(a="caps"),s==J&&(a="esc"),s==L&&(a="pageup"),s==M&&(a="padedown"),s==N&&(a="end"),s==O&&(a="home"),s==Q&&(a="leftarrow"),s==R&&(a="uparrow"),s==S&&(a="downarrow"),s==T&&(a="insert"),s==U&&(a="delete"),s==V&&(a="winleft"),s==W&&(a="winright"),s==X&&(a="select"),s==Z&&(a=1),s==$&&(a=2),s==_&&(a=3),s==ea&&(a=4),s==aa&&(a=5),s==sa&&(a=6),s==ca&&(a=7),s==ra&&(a=8),s==oa&&(a=9),s==Y&&(a=0),s==ta&&(a=1),s==fa&&(a=2),s==na&&(a=3),s==da&&(a=4),s==ia&&(a=5),s==pa&&(a=6),s==ua&&(a=7),s==ha&&(a=8),s==ma&&(a=9),s==la&&(a=0),s==wa&&(a="times"),s==ka&&(a="add"),s==ga&&(a="minus"),s==ba&&(a="decimal"),s==va&&(a="devide"),s==qa&&(a="f1"),s==ya&&(a="f2"),s==ja&&(a="f3"),s==xa&&(a="f4"),s==za&&(a="f5"),s==Ca&&(a="f6"),s==Ka&&(a="f7"),s==Pa&&(a="f8"),s==Aa&&(a="f9"),s==Ba&&(a="f10"),s==Da&&(a="f11"),s==Ea&&(a="f12"),s==c&&(a="a"),s==r&&(a="b"),s==o&&(a="c"),s==l&&(a="d"),s==t&&(a="e"),s==f&&(a="f"),s==n&&(a="g"),s==d&&(a="h"),s==i&&(a="i"),s==p&&(a="j"),s==u&&(a="k"),s==h&&(a="l"),s==m&&(a="m"),s==w&&(a="n"),s==k&&(a="o"),s==g&&(a="p"),s==b&&(a="q"),s==v&&(a="r"),s==q&&(a="s"),s==y&&(a="t"),s==j&&(a="u"),s==x&&(a="v"),s==z&&(a="w"),s==C&&(a="x"),s==K&&(a="y"),s==P&&(a="z"),s==A&&(a="space"),a}_x000D_

Spring Boot by default has a “whitelabel” error page which you can see in a browser if you encounter a server error. Whitelabel Error Page is a generic Spring Boot error page which is displayed when no custom error page is found.
Set “server.error.whitelabel.enabled=false” to switch of the default error page
This is a very different style of programming, but I always try to rewrite things that looked like
bar = None
if foo():
bar = "Baz"
if bar is None:
bar = "Quux"
into just:
if foo():
bar = "Baz"
else:
bar = "Quux"
That is to say, I try hard to avoid a situation where some code paths define variables but others don't. In my code, there is never a path which causes an ambiguity of the set of defined variables (In fact, I usually take it a step further and make sure that the types are the same regardless of code path). It may just be a matter of personal taste, but I find this pattern, though a little less obvious when I'm writing it, much easier to understand when I'm later reading it.
For me, it's very simple:
private boolean mLoading = false;
mList.setOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
int totalItem = mLinearLayoutManager.getItemCount();
int lastVisibleItem = mLinearLayoutManager.findLastVisibleItemPosition();
if (!mLoading && lastVisibleItem == totalItem - 1) {
mLoading = true;
// Scrolled to bottom. Do something here.
mLoading = false;
}
}
});
Be careful with asynchronous jobs: mLoading must be changed at the end of the asynchronous jobs. Hope it will be helpful!
How is the
__getattribute__
method used?
It is called before the normal dotted lookup. If it raises AttributeError
, then we call __getattr__
.
Use of this method is rather rare. There are only two definitions in the standard library:
$ grep -Erl "def __getattribute__\(self" cpython/Lib | grep -v "/test/"
cpython/Lib/_threading_local.py
cpython/Lib/importlib/util.py
Best Practice
The proper way to programmatically control access to a single attribute is with property
. Class D
should be written as follows (with the setter and deleter optionally to replicate apparent intended behavior):
class D(object):
def __init__(self):
self.test2=21
@property
def test(self):
return 0.
@test.setter
def test(self, value):
'''dummy function to avoid AttributeError on setting property'''
@test.deleter
def test(self):
'''dummy function to avoid AttributeError on deleting property'''
And usage:
>>> o = D()
>>> o.test
0.0
>>> o.test = 'foo'
>>> o.test
0.0
>>> del o.test
>>> o.test
0.0
A property is a data descriptor, thus it is the first thing looked for in the normal dotted lookup algorithm.
__getattribute__
You several options if you absolutely need to implement lookup for every attribute via __getattribute__
.
AttributeError
, causing __getattr__
to be called (if implemented)super
to call the parent (probably object
's) implementation__getattr__
For example:
class NoisyAttributes(object):
def __init__(self):
self.test=20
self.test2=21
def __getattribute__(self, name):
print('getting: ' + name)
try:
return super(NoisyAttributes, self).__getattribute__(name)
except AttributeError:
print('oh no, AttributeError caught and reraising')
raise
def __getattr__(self, name):
"""Called if __getattribute__ raises AttributeError"""
return 'close but no ' + name
>>> n = NoisyAttributes()
>>> nfoo = n.foo
getting: foo
oh no, AttributeError caught and reraising
>>> nfoo
'close but no foo'
>>> n.test
getting: test
20
And this example shows how you might do what you originally wanted:
class D(object):
def __init__(self):
self.test=20
self.test2=21
def __getattribute__(self,name):
if name=='test':
return 0.
else:
return super(D, self).__getattribute__(name)
And will behave like this:
>>> o = D()
>>> o.test = 'foo'
>>> o.test
0.0
>>> del o.test
>>> o.test
0.0
>>> del o.test
Traceback (most recent call last):
File "<pyshell#216>", line 1, in <module>
del o.test
AttributeError: test
Your code with comments. You have a dotted lookup on self in __getattribute__
.
This is why you get a recursion error. You could check if name is "__dict__"
and use super
to workaround, but that doesn't cover __slots__
. I'll leave that as an exercise to the reader.
class D(object):
def __init__(self):
self.test=20
self.test2=21
def __getattribute__(self,name):
if name=='test':
return 0.
else: # v--- Dotted lookup on self in __getattribute__
return self.__dict__[name]
>>> print D().test
0.0
>>> print D().test2
...
RuntimeError: maximum recursion depth exceeded in cmp
At the moment I'm writing this, the trick with m.facebook.com no longer works (at least for me) and user is redirected to the mobile FB login page which obviously is not good for UX.
Fortunately, FB PHP SDK has a semi-documented solution (in case the link doesn't lead to getLogoutUrl()
function, just search look for it on that page). This is also mentioned in at least one other on StackOverflow: Facebook php SDK getLogoutUrl() problem.
BTW I've just noticed that Zach Greenberg got it right in this question, but I'm adding my answer as a summary for Python developers.
So here is the controller code.
public IActionResult AddURLTest()
{
return ViewComponent("AddURL");
}
You can load it using JQuery load method.
$(document).ready (function(){
$("#LoadSignIn").click(function(){
$('#UserControl').load("/Home/AddURLTest");
});
});

Running from the command line means running from the terminal or DOS shell. You are running it from Python itself.
On the anaconda prompt, do a
conda -V
or conda --version
to get the conda version.python -V
or python --version
to get the python version.conda list anaconda$
to get the Anaconda version.conda list
to get the Name, Version, Build & Channel details of all the packages installed (in the current environment).conda info
to get all the current environment details.conda info --envs
To see a list of all your environmentsI have the same problem. I avoid it with remove.packages("Package making this confusion")
and it works. In my case, I don't need the second package, so that is not a very good idea.
The way I like to do this is to convert both the original set and the values I'd like to add into lists, add them, and then convert them back into a set, like this:
setMenu = {"Eggs", "Bacon"}
print(setMenu)
> {'Bacon', 'Eggs'}
setMenu = set(list(setMenu) + list({"Spam"}))
print(setMenu)
> {'Bacon', 'Spam', 'Eggs'}
setAdditions = {"Lobster", "Sausage"}
setMenu = set(list(setMenu) + list(setAdditions))
print(setMenu)
> {'Lobster', 'Spam', 'Eggs', 'Sausage', 'Bacon'}
This way I can also easily add multiple sets using the same logic, which gets me an TypeError: unhashable type: 'set'
if I try doing it with the .update()
method.

For Spring Boot, the accepted answer will overwrite duplicate properties with lower priority ones. This solution will collect the properties into a SortedMap
and take only the highest priority duplicate properties.
final SortedMap<String, String> sortedMap = new TreeMap<>();
for (final PropertySource<?> propertySource : env.getPropertySources()) {
if (!(propertySource instanceof EnumerablePropertySource))
continue;
for (final String name : ((EnumerablePropertySource<?>) propertySource).getPropertyNames())
sortedMap.computeIfAbsent(name, propertySource::getProperty);
}

Using pure javascript you can use Window.scrollX and Window.scrollY
window.addEventListener("scroll", function(event) {
var top = this.scrollY,
left =this.scrollX;
}, false);
Notes
The pageXOffset property is an alias for the scrollX property, and The pageYOffset property is an alias for the scrollY property:
window.pageXOffset == window.scrollX; // always true
window.pageYOffset == window.scrollY; // always true
Here is a quick demo
window.addEventListener("scroll", function(event) {_x000D_
_x000D_

here is a simple way of calculating age:
//dob date dd/mm/yy
var d = 01/01/1990
//today
//date today string format
var today = new Date(); // i.e wed 04 may 2016 15:12:09 GMT
//todays year
var todayYear = today.getFullYear();
// today month
var todayMonth = today.getMonth();
//today date
var todayDate = today.getDate();
//dob
//dob parsed as date format
var dob = new Date(d);
// dob year
var dobYear = dob.getFullYear();
// dob month
var dobMonth = dob.getMonth();
//dob date
var dobDate = dob.getDate();
var yearsDiff = todayYear - dobYear ;
var age;
if ( todayMonth < dobMonth )
{
age = yearsDiff - 1;
}
else if ( todayMonth > dobMonth )
{
age = yearsDiff ;
}
else //if today month = dob month
{ if ( todayDate < dobDate )
{
age = yearsDiff - 1;
}
else
{
age = yearsDiff;
}
}
If you have a unique key, you may use COUNT(*) OVER ( ORDER BY unique_key ) as ROWNUM
SELECT t.*, count(*) OVER (ORDER BY k ) ROWNUM
FROM yourtable t;
| k | n | rownum |
|---|-------|--------|
| a | TEST1 | 1 |
| b | TEST2 | 2 |
| c | TEST2 | 3 |
| d | TEST4 | 4 |
int? is shorthand for Nullable<int>
.
This may be the post you were looking for.
Maybe it can be useful to know that the bitwise AND and bitwise OR operators are always evaluated before conditional AND and conditional OR used in the same expression.

Simply create a new external tool configuration (from Eclipse Run -> External Tools)

Here's a more technical and thorough answer to an old question: Visual Basic for Applications (VBA) and Visual Basic (pre-.NET) are not just similar languages, they are the same language. Specifically:
In an old VB reference book I came across last year, the author (Paul Lomax) even asserted that 'VBA' has always been the name of the language itself, whether used in stand-alone applications or in embedded contexts (such as MS Office):
"Before we go any further, let's just clarify on fundamental point. Visual Basic for Applications (VBA) is the language used to program in Visual Basic (VB). VB itself is a development environment; the language element of that environment is VBA."
The minor differences
Hosted vs. stand-alone: In practical, terms, when most people say "VBA" they specifically mean "VBA when used in MS Office", and they say "VB6" to mean "VBA used in the last version of the standalone VBA compiler (i.e. Visual Studio 6)". The IDE and compiler bundled with MS Office is almost identical to Visual Studio 6, with the limitation that it does not allow compilation to stand-alone dll or exe files. This in turns means that classes defined in embedded VBA projects are not accessible from non-embedded COM consumers, because they cannot be registered.
Continued development: Microsoft stopped producing a stand-alone VBA compiler with Visual Studio 6, as they switched to the .NET runtime as the platform of choice. However, the MS Office team continues to maintain VBA, and even released a new version (VBA7) with a new VM (now just called VBA7.dll) starting with MS Office 2010. The only major difference is that VBA7 has both a 32- and 64-bit version and has a few enhancements to handle the differences between the two, specifically with regards to external API invocations.
Try this test:
any(substring in string for substring in substring_list)
It will return True
if any of the substrings in substring_list
is contained in string
.
Note that there is a Python analogue of Marc Gravell's answer in the linked question:
from itertools import imap
any(imap(string.__contains__, substring_list))
In Python 3, you can use map
directly instead:
any(map(string.__contains__, substring_list))
Probably the above version using a generator expression is more clear though.
if let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory,

Long time since I've done Assembly programming, but this link might be useful...
The processor has a collection of registers which are used to store data. Some of these are direct values while others are pointing to an area within RAM. Registers do tend to be used for certain specific actions and every operand in assembly will require a certain amount of data in specific registers.
The stack pointer is mostly used when you're calling other procedures. With modern compilers, a bunch of data will be dumped first on the stack, followed by the return address so the system will know where to return once it's told to return. The stack pointer will point at the next location where new data can be pushed to the stack, where it will stay until it's popped back again.
Base registers or segment registers just point to the address space of a large amount of data. Combined with a second regiser, the Base pointer will divide the memory in huge blocks while the second register will point at an item within this block. Base pointers therefor point to the base of blocks of data.
Do keep in mind that Assembly is very CPU specific. The page I've linked to provides information about different types of CPU's.
string remove = Regex.Replace(txtsp.Value).ToUpper(), @"\t|\n|\r", "");
It may seem as being too cautious, but I frequently zip a copy of whatever I've been working on before I make source control changes. In a Gitlab project I'm working on, I recently deleted a remote branch by mistake that I wanted to keep after merging a merge request. It turns out all I had to do to get it back with the commit history was push again. The merge request was still tracked by Gitlab, so it still shows the blue 'merged' label to the right of the branch. I still zipped my local folder in case something bad happened.
I had the same issue with gcc "gnat1" and it was due to the path being wrong. Gnat1 was on version 4.6 but I was executing version 4.8.1, which I had installed. As a temporary solution, I copied gnat1 from 4.6 and pasted under the 4.8.1 folder.
The path to gcc on my computer is /usr/lib/gcc/i686-linux-gnu/
You can find the path by using the find command:
find /usr -name "gnat1"
In your case you would look for cc1plus:
find /usr -name "cc1plus"
Of course, this is a quick solution and a more solid answer would be fixing the broken path.
I only needed to add the feature in windows features as Charlie mentioned.For people who cannot find it on window 10 or server 2012+ find it as below. I struggled a bit
In C, int
, char
, long
, etc. are all integers.
They typically have different memory sizes and thus different ranges as in INT_MIN
to INT_MAX
. char
and arrays of char
are often used to store characters and strings. Integers are stored in many types: int
being the most popular for a balance of speed, size and range.
ASCII is by far the most popular character encoding, but others exist. The ASCII code for an 'A' is 65, 'a' is 97, '\n' is 10, etc. ASCII data is most often stored in a char
variable. If the C environment is using ASCII encoding, the following all store the same value into the integer variable.
int i1 = 'a';
int i2 = 97;
char c1 = 'a';
char c2 = 97;
To convert an int
to a char
, simple assign:
int i3 = 'b';
int i4 = i3;
char c3;
char c4;
c3 = i3;
// To avoid a potential compiler warning, use a cast `char`.
c4 = (char) i4;
This warning comes up because int
typically has a greater range than char
and so some loss-of-information may occur. By using the cast (char)
, the potential loss of info is explicitly directed.
To print the value of an integer:
printf("<%c>\n", c3); // prints <b>
// Printing a `char` as an integer is less common but do-able
printf("<%d>\n", c3); // prints <98>
// Printing an `int` as a character is less common but do-able.
// The value is converted to an `unsigned char` and then printed.
printf("<%c>\n", i3); // prints <b>
printf("<%d>\n", i3); // prints <98>
There are additional issues about printing such as using %hhu
or casting when printing an unsigned char
, but leave that for later. There is a lot to printf()
.
A one liner for you:
const OBJECT = {
'key1': 'value1',
'key2': 'value2',
'key3': 'value3',
'key4': 'value4'
};
const value = 'value2';
const key = Object.keys(OBJECT)[Object.values(OBJECT).indexOf(value)];
window.console.log(key); // = key2
<input type="file" id="picfile" name="picf" />
<input type="text" id="txtName" style="width: 144px;" />
$("#btncatsave").click(function () {
var Name = $("#txtName").val();
var formData = new FormData();
var totalFiles = document.getElementById("picfile").files.length;
var file = document.getElementById("picfile").files[0];
formData.append("FileUpload", file);
formData.append("Name", Name);
$.ajax({
type: "POST",
url: '/Category_Subcategory/Save_Category',
data: formData,
dataType: 'json',
contentType: false,
processData: false,
success: function (msg) {
alert(msg);
},
error: function (error) {
alert("errror");
}
});
});
[HttpPost]
public ActionResult Save_Category()
{
string Name=Request.Form[1];
if (Request.Files.Count > 0)
{
HttpPostedFileBase file = Request.Files[0];
}
}
To follow up on Ron's answer if using JQuery and putting it in application.js or the head section you need to wrap it in a ready() section...
$(document).ready(function() {
$('#my-link').click(function(event){
alert('Hooray!');
event.preventDefault(); // Prevent link from following its href
});
});
Or just :
var a:Int = 3
var b:Int = 3
println(pow(Double(a),Double(b)))
Another Simple way is to create & invoke the function validate()
when the form loads & when submit button is clicked.
By using checked
property we check whether the checkbox is selected or not.
cbox[0]
has an index 0
which is used to access the first value (i.e Male) with name="gender"
You can do the following:
function validate() {_x000D_
var cbox = document.forms["myForm"]["gender"];_x000D_
if (_x000D_
cbox[0].checked == false &&_x000D_
cbox[1].checked == false &&_x000D_
cbox[2].checked == false_x000D_
) {_x000D_
alert("Please Select Gender");_x000D_
return false;_x000D_
} else {_x000D_
alert("Successfully Submited");_x000D_
return true;_x000D_
}_x000D_
}
_x000D_
<form onload="return validate()" name="myForm">_x000D_
<input type="checkbox" name="gender" value="male"> Male_x000D_
_x000D_
<input type="checkbox" name="gender" value="female"> Female_x000D_
_x000D_
<input type="checkbox" name="gender" value="other"> Other <br>_x000D_
_x000D_
<input type="submit" name="submit" value="Submit" onclick="validate()">_x000D_
</form>
_x000D_
Demo: CodePen
Tests
On the Tests
class we will add an @XmlRootElement
annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData
property differs from the default mapping we will use the @XmlElement
annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted
package forum11221136;
import javax.xml.bind.annotation.*;
@XmlRootElement
public class Tests {
TestData testData;
@XmlElement(name="test-data")
public TestData getTestData() {
return testData;
}
public void setTestData(TestData testData) {
this.testData = testData;
}
}
TestData
On this class I used the @XmlType
annotation to specify the order in which the elements should be ordered in. I added a testData
property that appeared to be missing. I also used an @XmlElement
annotation for the same reason as in the Tests
class.
package forum11221136;
import java.util.List;
import javax.xml.bind.annotation.*;
@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
String title;
String book;
String count;
List<TestData> testData;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getBook() {
return book;
}
public void setBook(String book) {
this.book = book;
}
public String getCount() {
return count;
}
public void setCount(String count) {
this.count = count;
}
@XmlElement(name="test-data")
public List<TestData> getTestData() {
return testData;
}
public void setTestData(List<TestData> testData) {
this.testData = testData;
}
}
Demo
Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.
package forum11221136;
import java.io.File;
import javax.xml.bind.*;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Tests.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
File xml = new File("src/forum11221136/input.xml");
Tests tests = (Tests) unmarshaller.unmarshal(xml);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(tests, System.out);
}
}
There is no real ascii codes for these keys as such, you will need to check out the scan codes for these keys, known as Make and Break key codes as per helppc's information. The reason the codes sounds 'ascii' is because the key codes are handled by the old BIOS interrupt 0x16 and keyboard interrupt 0x9.
Normal Mode Num lock on Make Break Make Break Down arrow E0 50 E0 D0 E0 2A E0 50 E0 D0 E0 AA Left arrow E0 4B E0 CB E0 2A E0 4B E0 CB E0 AA Right arrow E0 4D E0 CD E0 2A E0 4D E0 CD E0 AA Up arrow E0 48 E0 C8 E0 2A E0 48 E0 C8 E0 AA
Hence by looking at the codes following E0 for the Make key code, such as 0x50, 0x4B, 0x4D, 0x48 respectively, that is where the confusion arise from looking at key-codes and treating them as 'ascii'... the answer is don't as the platform varies, the OS varies, under Windows it would have virtual key code corresponding to those keys, not necessarily the same as the BIOS codes, VK_UP, VK_DOWN, VK_LEFT, VK_RIGHT.. this will be found in your C++'s header file windows.h, as I recall in the SDK's include folder.
Do not rely on the key-codes to have the same 'identical ascii' codes shown here as the Operating system will reprogram the entire BIOS code in whatever the OS sees fit, naturally that would be expected because since the BIOS code is 16bit, and the OS (nowadays are 32bit protected mode), of course those codes from the BIOS will no longer be valid.
Hence the original keyboard interrupt 0x9 and BIOS interrupt 0x16 would be wiped from the memory after the BIOS loads it and when the protected mode OS starts loading, it would overwrite that area of memory and replace it with their own 32 bit protected mode handlers to deal with those keyboard scan codes.
Here is a code sample from the old days of DOS programming, using Borland C v3:
#include <bios.h> int getKey(void){ int key, lo, hi; key = bioskey(0); lo = key & 0x00FF; hi = (key & 0xFF00) >> 8; return (lo == 0) ? hi + 256 : lo; }
This routine actually, returned the codes for up, down is 328 and 336 respectively, (I do not have the code for left and right actually, this is in my old cook book!) The actual scancode is found in the lo
variable. Keys other than the A-Z,0-9, had a scan code of 0 via the bioskey
routine.... the reason 256 is added, because variable lo
has code of 0 and the hi
variable would have the scan code and adds 256 on to it in order not to confuse with the 'ascii' codes...

I know this has been closed for a while, but I thought it might be useful to promote another async solution built on the requests library.
list_of_requests = ['http://moop.com', 'http://doop.com', ...]
from simple_requests import Requests
for response in Requests().swarm(list_of_requests):
print response.content
The docs are here: http://pythonhosted.org/simple-requests/
How about this?
puts "ok" if hash_variable["key"] == "X"
You can access hash values with the [] operator
You cannot define a variable of an incomplete type. You need to bring the whole definition of Cat
into scope before you can create the local variable in main
. I recommend that you move the definition of the type Cat
to a header and include it from the translation unit that has main
.
In Eclipse go to Window » Preferences then search for Formatter.
You will see various bold links,
click on each bold link
and set it to use spaces
instead of tabs
.
In the java formatter link, you have to edit the profile
and select the tab policy, spaces only
in indentation tab
var array: Int[][] = [[1,2,3],[4,5,6],[7,8,9]]
for first in array {
for second in first {
println("value \(second)")
}
}
To achieve what you're looking for you need to initialize the array to the correct template and then loop to add the row and column arrays:
var NumColumns = 27
var NumRows = 52
var array = Array<Array<Int>>()
var value = 1
for column in 0..NumColumns {
var columnArray = Array<Int>()
for row in 0..NumRows {
columnArray.append(value++)
}
array.append(columnArray)
}
println("array \(array)")
