This is the simplest way of printing the internal binary representation of an integer. For Example: If we take n as 17 then the output will be: 0000 0000 0000 0000 0000 0000 0001 0001
void bitPattern(int n) {
int mask = 1 << 31;
int count = 0;
while(mask != 0) {
if(count%4 == 0)
System.out.print(" ");
if((mask&n) == 0)
System.out.print("0");
else
System.out.print("1");
count++;
mask = mask >>> 1;
}
System.out.println();
}
You can jump through hoops and convert your solution to a lapply
, sapply
or apply
call. (I see @jonw shows one way to do this.) Other than that what you have already is perfectly acceptable code.
If these are all a time series or similar then the following might be a suitable alternative, which plots each series in it's own panel on a single plotting region. We use the zoo
package as it handles ordered data like this very well indeed.
require(zoo)
set.seed(1)
## example data
dat <- data.frame(X = cumsum(rnorm(100)), Y = cumsum(rnorm(100)),
Z = cumsum(rnorm(100)))
## convert to multivariate zoo object
datz <- zoo(dat)
## plot it
plot(datz)
Which gives:
Yes, you can!
$str = 'One';
$class = 'Class'.$str;
$object = new $class();
When using namespaces, supply the fully qualified name:
$class = '\Foo\Bar\MyClass';
$instance = new $class();
Other cool stuff you can do in php are:
Variable variables:
$personCount = 123;
$varname = 'personCount';
echo $$varname; // echo's 123
And variable functions & methods.
$func = 'my_function';
$func('param1'); // calls my_function('param1');
$method = 'doStuff';
$object = new MyClass();
$object->$method(); // calls the MyClass->doStuff() method.
This is not exactly a hot topic, but I have a factory class that allows a dll to create an instance and return it as a DLL. It is what I came looking for but couldn't find exactly.
It is called like,
IHTTP_Server *server = SN::SN_Factory<IHTTP_Server>::CreateObject();
IHTTP_Server *server2 =
SN::SN_Factory<IHTTP_Server>::CreateObject(IHTTP_Server_special_entry);
where IHTTP_Server is the pure virtual interface for a class created either in another DLL, or the same one.
DEFINE_INTERFACE is used to give a class id an interface. Place inside interface;
An interface class looks like,
class IMyInterface
{
DEFINE_INTERFACE(IMyInterface);
public:
virtual ~IMyInterface() {};
virtual void MyMethod1() = 0;
...
};
The header file is like this
#if !defined(SN_FACTORY_H_INCLUDED)
#define SN_FACTORY_H_INCLUDED
#pragma once
The libraries are listed in this macro definition. One line per library/executable. It would be cool if we could call into another executable.
#define SN_APPLY_LIBRARIES(L, A) \
L(A, sn, "sn.dll") \
L(A, http_server_lib, "http_server_lib.dll") \
L(A, http_server, "")
Then for each dll/exe you define a macro and list its implementations. Def means that it is the default implementation for the interface. If it is not the default, you give a name for the interface used to identify it. Ie, special, and the name will be IHTTP_Server_special_entry.
#define SN_APPLY_ENTRYPOINTS_sn(M) \
M(IHTTP_Handler, SNI::SNI_HTTP_Handler, sn, def) \
M(IHTTP_Handler, SNI::SNI_HTTP_Handler, sn, special)
#define SN_APPLY_ENTRYPOINTS_http_server_lib(M) \
M(IHTTP_Server, HTTP::server::server, http_server_lib, def)
#define SN_APPLY_ENTRYPOINTS_http_server(M)
With the libraries all setup, the header file uses the macro definitions to define the needful.
#define APPLY_ENTRY(A, N, L) \
SN_APPLY_ENTRYPOINTS_##N(A)
#define DEFINE_INTERFACE(I) \
public: \
static const long Id = SN::I##_def_entry; \
private:
namespace SN
{
#define DEFINE_LIBRARY_ENUM(A, N, L) \
N##_library,
This creates an enum for the libraries.
enum LibraryValues
{
SN_APPLY_LIBRARIES(DEFINE_LIBRARY_ENUM, "")
LastLibrary
};
#define DEFINE_ENTRY_ENUM(I, C, L, D) \
I##_##D##_entry,
This creates an enum for interface implementations.
enum EntryValues
{
SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_ENUM)
LastEntry
};
long CallEntryPoint(long id, long interfaceId);
This defines the factory class. Not much to it here.
template <class I>
class SN_Factory
{
public:
SN_Factory()
{
}
static I *CreateObject(long id = I::Id )
{
return (I *)CallEntryPoint(id, I::Id);
}
};
}
#endif //SN_FACTORY_H_INCLUDED
Then the CPP is,
#include "sn_factory.h"
#include <windows.h>
Create the external entry point. You can check that it exists using depends.exe.
extern "C"
{
__declspec(dllexport) long entrypoint(long id)
{
#define CREATE_OBJECT(I, C, L, D) \
case SN::I##_##D##_entry: return (int) new C();
switch (id)
{
SN_APPLY_CURRENT_LIBRARY(APPLY_ENTRY, CREATE_OBJECT)
case -1:
default:
return 0;
}
}
}
The macros set up all the data needed.
namespace SN
{
bool loaded = false;
char * libraryPathArray[SN::LastLibrary];
#define DEFINE_LIBRARY_PATH(A, N, L) \
libraryPathArray[N##_library] = L;
static void LoadLibraryPaths()

SN_APPLY_LIBRARIES(DEFINE_LIBRARY_PATH, "")
}
typedef long(*f_entrypoint)(long id);
f_entrypoint libraryFunctionArray[LastLibrary - 1];

}
#define DEFAULT_LIBRARY_ENTRY(A, N, L) \

SN_APPLY_CURRENT_LIBRARY(DEFAULT_LIBRARY_ENTRY, "")
}
enum SN::LibraryValues libraryForEntryPointArray[SN::LastEntry];
#define DEFINE_ENTRY_POINT_LIBRARY(I, C, L, D) \
libraryForEntryPointArray[I##_##D##_entry] = L##_library;
void LoadLibraryForEntryPointArray()
{
SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_POINT_LIBRARY)
}
enum SN::EntryValues defaultEntryArray[SN::LastEntry];
#define DEFINE_ENTRY_DEFAULT(I, C, L, D) \
defaultEntryArray[I##_##D##_entry] = I##_def_entry;
void LoadDefaultEntries()
{
SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_DEFAULT)
}
void Initialize()
{
if (!loaded)
{
loaded = true;
LoadLibraryPaths();
InitlibraryFunctionArray();
LoadLibraryForEntryPointArray();
LoadDefaultEntries();
}
}
long CallEntryPoint(long id, long interfaceId)
{
Initialize();
// assert(defaultEntryArray[id] == interfaceId, "Request to create an object for the wrong interface.")
enum SN::LibraryValues l = libraryForEntryPointArray[id];
f_entrypoint f = libraryFunctionArray[l];
if (!f)
{
HINSTANCE hGetProcIDDLL = LoadLibraryA(libraryPathArray[l]);
if (!hGetProcIDDLL) {
return NULL;
}
// resolve function address here
f = (f_entrypoint)GetProcAddress(hGetProcIDDLL, "entrypoint");
if (!f) {
return NULL;
}
libraryFunctionArray[l] = f;
}
return f(id);
}
}
Each library includes this "cpp" with a stub cpp for each library/executable. Any specific compiled header stuff.
#include "sn_pch.h"
Setup this library.
#define SN_APPLY_CURRENT_LIBRARY(L, A) \
L(A, sn, "sn.dll")
An include for the main cpp. I guess this cpp could be a .h. But there are different ways you could do this. This approach worked for me.
#include "../inc/sn_factory.cpp"
states = "Alaska Alabama Arkansas American Samoa Arizona California Colorado"
states_list = states.split (' ')
Because most of the answer here didn't work, or only partially worked:
body.modal-open .modal[style]:not([style='display: none;']) {
display: flex !important;
height: 100%;
}
body.modal-open .modal[style]:not([style='display: none;']) .modal-dialog {
margin: auto;
}
You have to use the [style] selector to only apply the style on the modal that is currently active instead of all the modals. .in
would have been great, but it appears to be added only after the transition is complete which is too late and makes for some really bad transitions. Fortunately it appears bootstrap always applies a style attribute on the modal just as it is starting to show so this is a bit hacky, but it works.
The :not([style='display: none;'])
portion is a workaround to bootstrap not correctly removing the style attribute and instead setting the style display to none when you close the dialog.

This error message...
SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 81
...implies that the ChromeDriver v81 was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser where is version is other then 81.0.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
So, it's quite evident your have chromedriver=81.0 present within your system and is present within the system PATH
variable which gets invoked while you:
driver = webdriver.Chrome()
There are two solutions:
Or you can override the default chromedriver v81.0 binary location with chromedriver v80.0 binary location as follows:
from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')
You can find a couple of relevant discussions in:
This works, too.
<input style="width:300px; height:55px; font-size:50px;" />
A CSS stylesheet looks better though, and can easily be used over multiple pages.
The message you mention is quite clear:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
SLF4J API could not find a binding, and decided to default to a NOP implementation. In your case slf4j-log4j12.jar was somehow not visible when the LoggerFactory class was loaded into memory, which is admittedly very strange. What does "mvn dependency:tree" tell you?
The various dependency declarations may not even be directly at cause here. I strongly suspect that a pre-1.6 version of slf4j-api.jar
is being deployed without your knowledge.
If you need to split something into 3 pieces, such as an email address and you don't know the length of the middle part, try this (I just ran this on sqlserver 2012 so I know it works):
SELECT top 2000
emailaddr_ as email,
SUBSTRING(emailaddr_, 1,CHARINDEX('@',emailaddr_) -1) as username,
SUBSTRING(emailaddr_, CHARINDEX('@',emailaddr_)+1, (LEN(emailaddr_) - charindex('@',emailaddr_) - charindex('.',reverse(emailaddr_)) )) domain
FROM
emailTable
WHERE
charindex('@',emailaddr_)>0
AND
charindex('.',emailaddr_)>0;
GO
Hope this helps.
In my case, I also had to add the line "FcgidMaxRequestLen 1073741824" (without the quotes) in /etc/apache2/mods-available/fcgid.conf. It's documented here http://forum.ispsystem.com/en/showthread.php?p=6611 . Since mod_fcgid 2.3.6, they changed the default for FcgidMaxRequestLen from 1GB to 128K (see https://svn.apache.org/repos/asf/httpd/mod_fcgid/trunk/CHANGES-FCGID )
Remove those char * ret
declarations inside if
blocks which hide outer ret
. Therefor you have memory leak and on the other hand un-allocated memory for ret
.
To compare a c-style string you should use strcmp(array,"")
not array!=""
. Your final code should looks like below:
char* appendCharToCharArray(char* array, char a)
{
size_t len = strlen(array);
char* ret = new char[len+2];
strcpy(ret, array);
ret[len] = a;
ret[len+1] = '\0';
return ret;
}
Note that, you must handle the allocated memory of returned ret
somewhere by delete[]
it.
Why you don't use std::string
? it has .append
method to append a character at the end of a string:
std::string str;
str.append('x');
// or
str += x;
It depends on the tablix structure you are using. In a table, for example, you do not have column groups, so Reporting Services does not recognize which textboxes are the column headers and setting RepeatColumnHeaders property to True doesn't work.
Instead, you need to:
RepeatOnNewPage
property to True.
KeepWithGroup
property is set to After
.The KeepWithGroup
property specifies which group to which the static member needs to stick. If set to After
then the static member sticks with the group after it, or below it, acting as a group header. If set to Before
, then the static member sticks with the group before, or above it, acting as a group footer. If set to None
, Reporting Services decides where to put the static member.
Now when you view the report, the column headers repeat on each page of the tablix.
This video shows how to set it exactly as the answer described.
You can use Amazon Corretto. It is free to use multiplatform, production-ready distribution of the OpenJDK. It comes with long-term support that will include performance enhancements and security fixes. Check the installation instructions here.
You can also check Zulu from Azul.
One more thing I like to highlight here is both Amazon Corretto and Zulu are TCK Compliant. You can see the OpenJDK builds comparison here and here.
if(empty(array_intersect([21,22,23,24], $check_with_this)) {
print "Not found even a single element";
} else {
print "Found an element";
}
array_intersect() returns an array containing all the values of array1 that are present in all the arguments. Note that keys are preserved.
Returns an array containing all of the values in array1 whose values exist in all of the parameters.
empty() — Determine whether a variable is empty
Returns FALSE if var exists and has a non-empty, non-zero value. Otherwise returns TRUE.
return Deal::with(["redeem" => function($q){
$q->where('user_id', '=', 1);
}])->get();
this worked for me
Here are some helper functions I use:
Array.contains = function (arr, key) {
for (var i = arr.length; i--;) {
if (arr[i] === key) return true;
}
return false;
};
Array.add = function (arr, key, value) {
for (var i = arr.length; i--;) {
if (arr[i] === key) return arr[key] = value;
}
this.push(key);
};
Array.remove = function (arr, key) {
for (var i = arr.length; i--;) {
if (arr[i] === key) return arr.splice(i, 1);
}
};
You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.
Have you tried using System.Net.IPAddress just in case?
System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1"); //127.0.0.1 as an example
The docs on Microsoft's site have a complete example which works fine on my machine.
Yes, you should try to serve valid code if possible.
Most browsers will silently correct this error, but there is a problem with relying on the error handling in the browsers. There is no standard for how to handle incorrect code, so it's up to each browser vendor to try to figure out what to do with each error, and the results may vary.
Some examples where browsers are likely to react differently is if you put elements inside a table but outside the table cells, or if you nest links inside each other.
For your specific example it's not likely to cause any problems, but error correction in the browser might for example cause the browser to change from standards compliant mode into quirks mode, which could make your layout break down completely.
So, you should correct errors like this in the code, if not for anything else so to keep the error list in the validator short, so that you can spot more serious problems.

$myObj = new stdClass();
// OR
$myObj = (object) [
"foo" => "Foo value",
"bar" => "Bar value"
];
I love how easy is to create objects of anonymous type in JavaScript:
//JavaScript
var myObj = {
foo: "Foo value",
bar: "Bar value"
};
console.log(myObj.foo); //Output: Foo value
So I always try to write this kind of objects in PHP like javascript does:
//PHP >= 5.4
$myObj = (object) [
"foo" => "Foo value",
"bar" => "Bar value"
];
//PHP < 5.4
$myObj = (object) array(
"foo" => "Foo value",
"bar" => "Bar value"
);
echo $myObj->foo; //Output: Foo value
But as this is basically an array you can't do things like assign anonymous functions to a property like js does:
//JavaScript
var myObj = {
foo: "Foo value",
bar: function(greeting) {
return greeting + " bar";
}
};
console.log(myObj.bar("Hello")); //Output: Hello bar
//PHP >= 5.4
$myObj = (object) [
"foo" => "Foo value",
"bar" => function($greeting) {
return $greeting . " bar";
}
];
var_dump($myObj->bar("Hello")); //Throw 'undefined function' error
var_dump($myObj->bar); //Output: "object(Closure)"
Well, you can do it, but IMO isn't practical / clean:
$barFunc = $myObj->bar;
echo $barFunc("Hello"); //Output: Hello bar
Also, using this synthax you can find some funny surprises, but works fine for most cases.
div { margin: auto; }
This will center your div.
Div by itself is a blockelement. Therefor you need to define the style to the div how to behave.
Depending on what font you're using you can set max-width
on the paragraph with a calculated value. It will not be exact, but I've found that in most cases that does not matter.
p {
max-width: calc(30em * 0.5);
}
The number you multiply with depends on what font it is, and how much a character takes up in a em square. More characters = less accurate.
You can use the instanceof operator to test to see if it is a double prior to casting. You can then safely cast it to a double. In addition you can test it against other known types (e.g. Integer) and then coerce them into a double manually if desired.
Double d = null;
if (obj instanceof Double) {
d = (Double) obj;
}
The documentation is misleading.
I have the following code running in production
DECLARE @table TABLE (UserID varchar(100))
DECLARE @sql varchar(1000)
SET @sql = 'spSelUserIDList'
/* Will also work
SET @sql = 'SELECT UserID FROM UserTable'
*/
INSERT INTO @table
EXEC(@sql)
SELECT * FROM @table
This is actually the conventional use of the break
statement. If the break
statement wasn't nested in an if
block the for
loop could only ever execute one time.
MSDN lists this as their example for the break
statement.
another solution is catching onClick event and for aggregate data to js function you can
.hmtl.erb
<%= link_to "Action", 'javascript:;', class: 'my-class', data: { 'array' => %w(foo bar) } %>
.js
// handle my-class click
$('a.my-class').on('click', function () {
var link = $(this);
var array = link.data('array');
});
You can use json
like the following example.
PHP code:
echo json_encode($array);
$array
is array data, and the jQuery code is:
$.get("period/education/ajaxschoollist.php?schoolid="+schoolid, function(responseTxt, statusTxt, xhr){
var a = JSON.parse(responseTxt);
$("#hideschoolid").val(a.schoolid);
$("#section_id").val(a.section_id);
$("#schoolname").val(a.schoolname);
$("#country_id").val(a.country_id);
$("#state_id").val(a.state_id);
}
You can have class something like below from which you can add 'n' number of functions or console_scripts you want to execute in parallel passion and start the execution and wait for all jobs to complete..
from multiprocessing import Process
class ProcessParallel(object):
"""
To Process the functions parallely
"""
def __init__(self, *jobs):
"""
"""
self.jobs = jobs
self.processes = []
def fork_processes(self):
"""

"""
for job in self.jobs:
proc = Process(target=job)
self.processes.append(proc)
def start_all(self):
"""
Starts the functions process all together.
"""
for proc in self.processes:
proc.start()
def join_all(self):
"""
Waits untill all the functions executed.
"""
for proc in self.processes:
proc.join()
def two_sum(a=2, b=2):
return a + b
def multiply(a=2, b=2):
return a * b
#How to run:
if __name__ == '__main__':
#note: two_sum, multiply can be replace with any python console scripts which
#you wanted to run parallel..
procs = ProcessParallel(two_sum, multiply)
#Add all the process in list
procs.fork_processes()
#starts process execution
procs.start_all()
#wait until all the process got executed
procs.join_all()
The size of a textarea can be specified by the cols and rows attributes, or even better; through CSS' height and width properties.
The cols attribute is supported in all major browsers.
One main difference is that <TEXTAREA ...>
is a container tag: it has a start tag ().
#include <iostream>
using namespace std ;
typedef int (*Type)[3][3] ;
Type Demo_function( Type ); //prototype
int main (){
cout << "\t\t!!!!!Passing and returning 2D array from function!!!!!\n"
int array[3][3] ;
Type recieve , ptr = &array;
recieve = Demo_function( ptr ) ;
for ( int i = 0 ; i < 3 ; i ++ ){
for ( int j = 0 ; j < 3 ; j ++ ){
cout << (*recieve)[i][j] << " " ;
}
cout << endl ;
}
return 0 ;
}
Type Demo_function( Type array ){/*function definition */
cout << "Enter values : \n" ;
for (int i =0 ; i < 3 ; i ++)
for ( int j = 0 ; j < 3 ; j ++ )
cin >> (*array)[i][j] ;
return array ;
}
Set the max-width:1250px;
that is currently on your body on your #container. This way your header will be 100% of his parent (body) :)
Another working example:
var zlib = require('zlib');
var tar = require('tar');
var ftp = require('ftp');
var files = [];
var conn = new ftp();
conn.on('connect', function(e)

conn.auth(function(e)
{
if (e)
{
throw e;
}
conn.get('/tz/tzdata-latest.tar.gz', function(e, stream)
{
stream.on('success', function()
{
conn.end();
console.log("Processing files ...");
for (var name in files)
{
var file = files[name];
console.log("filename: " + name);
console.log(file);
}
console.log("OK")
});
stream.on('error', function(e)
{
console.log('ERROR during get(): ' + e);
conn.end();
});
console.log("Reading ...");
stream

});
});
});
})

You may interest in using php's inbuilt function realpath(). and passing a constant DIR
for example: $TargetDirectory = realpath(__DIR__."/../.."); //Will take you 2 folder's back
String realpath() :: Returns canonicalized absolute pathname ..
To add the reference to "System.Windows.Forms", it seems to be a little different for Visual Studio Community 2017.
1) Go to solution explorer and select references
2) Right-click and select Add references
3) In Assemblies, check System.Windows.Forms and press ok
4) That's it.
I just wanted to know if the dictionary i was going to try to pull data from had data in it in the first place, this seems to be simplest way.

bool(d)
#should return
True
Just return your existing check from a function.

Ok found the answer. exchange()
is the best way. Oddly the HttpEntity
class doesn't have a setBody()
method (it has getBody()
), but it is still possible to set the request body, via the constructor.
// Create the request body as a MultiValueMap
MultiValueMap<String, String> body = new LinkedMultiValueMap<String, String>();
body.add("field", "value");
// Note the body object as first parameter!
HttpEntity<?> httpEntity = new HttpEntity<Object>(body, requestHeaders);
ResponseEntity<MyModel> response = restTemplate.exchange("/api/url", HttpMethod.POST, httpEntity, MyModel.class);
While not elegant, I opted for a simpler version that doesn't use NameValueCollecitons
- just a builder pattern wrapped around StringBuilder
.
public class UrlBuilder

_builder = new StringBuilder(urlBase);
}
#endregion Constructor
#region Methods
public UrlBuilder AppendParameter(string paramName, string value)
{
if (_builder.ToString().Contains("?"))
_builder.Append("&");
else
_builder.Append("?");
_builder.Append(HttpUtility.UrlEncode(paramName));
_builder.Append("=");
_builder.Append(HttpUtility.UrlEncode(value));
return this;
}
public override string ToString()
{
return _builder.ToString();
}
#endregion Methods
}
Per existing answers, I made sure to use HttpUtility.UrlEncode
calls. It's used like so:
string url = new UrlBuilder("http://www.somedomain.com/")
.AppendParameter("a", "true")
.AppendParameter("b", "muffin")
.AppendParameter("c", "muffin button")
.ToString();
// Result: http://www.somedomain.com?a=true&b=muffin&c=muffin%20button
Java Character class has an isLetterOrDigit method since version 1.0.2
Another option is to use an array, e.g.
void method(SomeClass[] v) { v[0] = ...; }
but 1) the array must be initialized before method invoked, 2) still one cannot implement e.g. swap method in this way...
This way is used in JDK, e.g. in java.util.concurrent.atomic.AtomicMarkableReference.get(boolean[])
.
for set empty all input such textarea select and input run this code:

Something like this should work:
String strImport = "For some reason my ?double quotes? were lost.";
strImport = strImport.replaceAll("\uFFFD", "\"");
I would like to present another answer to this as the currently accepted answer doesn't work for me (I use LibreOffice). This solution should work in Excel, LibreOffice and OpenOffice:
First, insert a new row at the beginning of the sheet. Within that row, define the names you need:
Then, in the menu bar, go to View -> Freeze Cells -> Freeze First Row. It'll look like this now:
Now whenever you scroll down in the document, the first row will be "pinned" to the top:
This is another solution for folks who love recursion.
The idea is simple. Divide up input by half and swap the two halves, continue until it reaches single bit.
Illustrated in the example below.
Ex : If Input is 00101010 ==> Expected output is 01010100
1. Divide the input into 2 halves
0010 --- 1010
2. Swap the 2 Halves
1010 0010
3. Repeat the same for each half.
10 -- 10 --- 00 -- 10
10 10 10 00
1-0 -- 1-0 --- 1-0 -- 0-0
0 1 0 1 0 1 0 0
Done! Output is 01010100
Here is a recursive function to solve it. (Note I have used unsigned ints, so it can work for inputs up to sizeof(unsigned int)*8 bits.
The recursive function takes 2 parameters - The value whose bits need to be reversed and the number of bits in the value.
int reverse_bits_recursive(unsigned int num, unsigned int numBits)
{
unsigned int reversedNum;;
unsigned int mask = 0;
mask = (0x1 << (numBits/2)) - 1;
if (numBits == 1) return num;
reversedNum = reverse_bits_recursive(num >> numBits/2, numBits/2) |
reverse_bits_recursive((num & mask), numBits/2) << numBits/2;
return reversedNum;
}
int main()
{
unsigned int reversedNum;
unsigned int num;
num = 0x55;
reversedNum = reverse_bits_recursive(num, 8);
printf ("Bit Reversal Input = 0x%x Output = 0x%x\n", num, reversedNum);
num = 0xabcd;
reversedNum = reverse_bits_recursive(num, 16);
printf ("Bit Reversal Input = 0x%x Output = 0x%x\n", num, reversedNum);
num = 0x123456;
reversedNum = reverse_bits_recursive(num, 24);
printf ("Bit Reversal Input = 0x%x Output = 0x%x\n", num, reversedNum);
num = 0x11223344;
reversedNum = reverse_bits_recursive(num,32);
printf ("Bit Reversal Input = 0x%x Output = 0x%x\n", num, reversedNum);
}
This is the output:
Bit Reversal Input = 0x55 Output = 0xaa
Bit Reversal Input = 0xabcd Output = 0xb3d5
Bit Reversal Input = 0x123456 Output = 0x651690
Bit Reversal Input = 0x11223344 Output = 0x22cc4488
Using nltk.
from nltk.tokenize import sent_tokenize, word_tokenize

You may use TweetTokenizer for parsing casual text with emoticons and such.
What I do in order to avoid having a polluted global scope is to create a script that I can include anywhere.
// my-script.js
const ActionsOverTime = require('@bigteam/node-aot').ActionsOverTime;
const config = require('../../config/config').actionsOverTime;
let aotInstance;
(function () {
if (!aotInstance) {
console.log('Create new aot instance');
aotInstance = ActionsOverTime.createActionOverTimeEmitter(config);
}
})();
exports = aotInstance;
Doing this will only create a new instance once and share that everywhere where the file is included. I am not sure if it is because the variable is cached or of it because of an internal reference mechanism for the application (that might include caching). Any comments on how node resolves this would be great.
Maybe also read this to get the gist on how require works: http://fredkschott.com/post/2014/06/require-and-the-module-system/
This cannot be done with pure HTML/JS, you will need CSS
CSS:
button {
width: 100%;
height: 100%;
}
Substitute 100% with required size
This can be done in many ways
I've now found this function on WordPress Codec,
which is a wrapper for $wp_query->get_queried_object
.
This post put me in the right direction, but it seems that it needs this update.
Adding the GridView1.DataBind() to the button click event did not work for me. However, adding it to the SqlDataSource1_Updated event did though.
Protected Sub SqlDataSource1_Updated(sender As Object, e As SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Updated

Try Server.UrlEncode()
, or System.Web.HttpUtility.UrlEncode()
for instances when you don't have access to the Server
object. You can also use System.Uri.EscapeUriString()
to avoid adding a reference to the System.Web
assembly.
if you want to know the install version of Xcode as well as Swift language current version:
Use below simple command by using Terminal:
1. To get install Xcode Version
xcodebuild -version
2. To get install Swift language Version
swift --version
For the use-case given here we may simply make use of the stopService()
method's return value. It returns true
if there exists the specified service and it is killed. Else it returns false
. So you may restart the service if the result is false
else it is assured that the current service has been stopped. :) It would be better if you have a look at this.
Python 3
from urllib.error import HTTPError
Python 2
from urllib2 import HTTPError
Just catch HTTPError
, handle it, and if it's not Error 404, simply use raise
to re-raise the exception.
See the Python tutorial.
e.g. complete example for Pyhton 2
import urllib2
from urllib2 import HTTPError
try:
urllib2.urlopen("some url")
except HTTPError as err:
if err.code == 404:
<whatever>
else:
raise
you should change cr_date(str) to datetime object then you 'll change the date to the specific format:
cr_date = '2013-10-31 18:23:29.000227'
cr_date = datetime.datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f')
cr_date = cr_date.strftime("%m/%d/%Y")
This is a perfect example of where you should use the macro recorder. Turn on the recorder and set the color of the cells through the UI. Stop the recorder and review the macro. It will generate a bunch of extraneous code, but it will also show you syntax that works for what you are trying to accomplish. Strip out what you don't need and modify (if you need to) what's left.
This is a simplified variation of Fernando's answer. This is for Linux and either Python 2 or 3. No external library is needed, and no external process is run.
import glob
def get_command_pid(command):
for path in glob.glob('/proc/*/comm'):
if open(path).read().rstrip() == command:
return path.split('/')[2]
Only the first matching process found will be returned, which works well for some purposes. To get the PIDs of multiple matching processes, you could just replace the return
with yield
, and then get a list with pids = list(get_command_pid(command))
.
Alternatively, as a single expression:
For one process:
next(path.split('/')[2] for path in glob.glob('/proc/*/comm') if open(path).read().rstrip() == command)
For multiple processes:
[path.split('/')[2] for path in glob.glob('/proc/*/comm') if open(path).read().rstrip() == command]
I expanded the Bootstrap table styles as Davide Pastore did, but with that method the styles are applied to all child tables as well, and they don't apply to the footer.
A better solution would be imitating the core Bootstrap table styles, but with your new class:
.table-borderless>thead>tr>th
.table-borderless>thead>tr>td
.table-borderless>tbody>tr>th
.table-borderless>tbody>tr>td
.table-borderless>tfoot>tr>th
.table-borderless>tfoot>tr>td {
border: none;
}
Then when you use <table class='table table-borderless'>
only the specific table with the class will be bordered, not any table in the tree.
SQL Developer will look in the following location in this order for a tnsnames.ora file
To see which one SQL Developer is using, issue the command show tns
in the worksheet
If your tnsnames.ora file is not getting recognized, use the following procedure:
Define an environmental variable called TNS_ADMIN to point to the folder that contains your tnsnames.ora file.
In Windows, this is done by navigating to Control Panel > System > Advanced system settings > Environment Variables...
In Linux, define the TNS_ADMIN variable in the .profile file in your home directory.
Confirm the os is recognizing this environmental variable
From the Windows command line: echo %TNS_ADMIN%
From linux: echo $TNS_ADMIN
Restart SQL Developer
Sometimes you want to have your GridView as simple as:
<asp:GridView ID="grid" runat="server" />
You don't want to specify any BoundField, you just want to bind your grid to DataReader. The following code helped me to format DateTime in this situation.
protected void Page_Load(object sender, EventArgs e)
{
grid.RowDataBound += grid_RowDataBound;
// Your DB access code here...
// grid.DataSource = cmd.ExecuteReader(CommandBehavior.CloseConnection);
// grid.DataBind();
}
void grid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow)
return;
var dt = (e.Row.DataItem as DbDataRecord).GetDateTime(4);
e.Row.Cells[4].Text = dt.ToString("dd.MM.yyyy");
}
The results shown here.
str = "aaaaabbbb"
newstr = str[-4:]
cat a.txt | xargs -d $'\n' sh -c 'for arg do command1 "$arg"; command2 "$arg"; ...; done' _
...or, without a Useless Use Of cat:
<a.txt xargs -d $'\n' sh -c 'for arg do command1 "$arg"; command2 "$arg"; ...; done' _
To explain some of the finer points:
The use of "$arg"
instead of %
(and the absence of -I
in the xargs
command line) is for security reasons: Passing data on sh
's command-line argument list instead of substituting it into code prevents content that data might contain (such as $(rm -rf ~)
, to take a particularly malicious example) from being executed as code.
Similarly, the use of -d $'\n'
is a GNU extension which causes xargs
to treat each line of the input file as a separate data item. Either this or -0
(which expects NULs instead of newlines) is necessary to prevent xargs from trying to apply shell-like (but not quite shell-compatible) parsing to the stream it reads. (If you don't have GNU xargs, you can use tr '\n' '\0' <a.txt | xargs -0 ...
to get line-oriented reading without -d
).
The _
is a placeholder for $0
, such that other data values added by xargs
become $1
and onward, which happens to be the default set of values a for
loop iterates over.
When pip
tells you that you already have protobuf
,
but PyCharm (or other) tells you that you don't have it,
it means that pip
and PyCharm are using a different Python interpreter.
This is a very common issue, especially on a Mac, with no standard Python package management.
The best way to completely eliminate such issues is using a virtualenv
per Python project, which is essentially a directory of Python packages and environment variable settings to isolate the Python environment of the project from everything else.
Create a virtualenv
for your project like this:
cd project
virtualenv --distribute virtualenv -p /path/to/python/executable
This creates a directory called virtualenv
inside your project.
(Make sure to configure your VCS (for example Git) to ignore this directory.)
To install packages in this virtualenv
, you need to activate the environment variable settings:
. virtualenv/bin/activate
Verify that pip
will use the right Python executable inside the virtualenv
, by running pip -V
. It should tell you the Python library path used, which should be inside the virtualenv
.
Now you can use pip
to install protobuf
as you did.
And finally, you need to make PyCharm use this virtualenv
instead of the system libraries. Somewhere in the project settings you can configure an interpreter for the project, select the Python executable inside the virtualenv
.
SELECT t.*,(select count(*) from city as tt where tt.name=t.name) as count FROM `city` as t where (select count(*) from city as tt where tt.name=t.name) > 1 order by count desc
Replace city with your Table. Replace name with your field name
Thanks to @Gerben's post came to know there are two events show.bs.tab (before the tab is shown) and shown.bs.tab (after the tab is shown) as explained in the docs - Bootstrap Tab usage
An additional solution if we're only interested in a specific tab, and maybe add separate functions without having to add an if - else block in one function, is to use the a href selector (maybe along with additional selectors if required)
$("a[href='#tab_target_id']").on('shown.bs.tab', function(e) {
console.log('shown - after the tab has been shown');
});
// or even this one if we want the earlier event
$("a[href='#tab_target_id']").on('show.bs.tab', function(e) {
console.log('show - before the new tab has been shown');
});
If you are using C# you should use Environment.NewLine
, which accordingly to MSDN it is:
A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.
The following example show you how to define a function in jQuery. You will see a button “Click here”, when you click on it, we call our function “myFunction()”.
$(document).ready(function(){
$.myFunction = function(){
alert('You have successfully defined the function!');
}
$(".btn").click(function(){
$.myFunction();
});
});
You can see an example here: How to define a function in jQuery?
You can escape the apostrophe with a \
character as well:
mystring.replace('\'', '')
The issue seems to be resolved in Python version 3.4.2.
testVar = input("Ask user for something.")
Will work fine.
No, the dataType
option is for parsing the received data.
To post JSON, you will need to stringify it yourself via JSON.stringify
and set the processData
option to false
.
$.ajax({
url: url,
type: "POST",
data: JSON.stringify(data),
processData: false,
contentType: "application/json; charset=UTF-8",
complete: callback
});
Note that not all browsers support the JSON
object, and although jQuery has .parseJSON
, it has no stringifier included; you'll need another polyfill library.
Adding my answer, because it elaborates the idea that you can SELECT multiple columns from the table from which you subquery.
Here I needed the the most recently cast cote and it's associated information.
I first tried simply to SELECT the max(votedate) along with vote, itemid, userid etc., but while the query would return the max votedate, it would also return the a random row for the other information. Hard to see among a bunch of 1s and 0s.
This worked well:
$query = "
SELECT t1.itemid, t1.itemtext, t2.vote, t2.votedate, t2.userid
FROM
(
SELECT itemid, itemtext FROM oc_item ) t1
LEFT JOIN
(
SELECT vote, votedate, itemid,userid FROM oc_votes
WHERE votedate IN
(select max(votedate) FROM oc_votes group by itemid)
AND userid=:userid) t2
ON (t1.itemid = t2.itemid)
order by itemid ASC
";
The subquery in the WHERE clause WHERE votedate IN (select max(votedate) FROM oc_votes group by itemid) returns one record - the record with the max vote date.
It's a mess. MAPI or CDO via a .NET interop DLL is officially unsupported by Microsoft--it will appear to work fine, but there are problems with memory leaks due to their differing memory models. You could use CDOEX, but that only works on the Exchange server itself, not remotely; useless. You could interop with Outlook, but now you've just made a dependency on Outlook; overkill. Finally, you could use Exchange 2003's WebDAV support, but WebDAV is complicated, .NET has poor built-in support for it, and (to add insult to injury) Exchange 2007 nearly completely drops WebDAV support.
What's a guy to do? I ended up using AfterLogic's IMAP component to communicate with my Exchange 2003 server via IMAP, and this ended up working very well. (I normally seek out free or open-source libraries, but I found all of the .NET ones wanting--especially when it comes to some of the quirks of 2003's IMAP implementation--and this one was cheap enough and worked on the first try. I know there are others out there.)
If your organization is on Exchange 2007, however, you're in luck. Exchange 2007 comes with a SOAP-based Web service interface that finally provides a unified, language-independent way of interacting with the Exchange server. If you can make 2007+ a requirement, this is definitely the way to go. (Sadly for me, my company has a "but 2003 isn't broken" policy.)
If you need to bridge both Exchange 2003 and 2007, IMAP or POP3 is definitely the way to go.

fs = require('fs'),
mongodb = require('mongodb'),
MongoClient = mongodb.MongoClient,
mongoDSN = 'mongodb://localhost:27017/test',
collection;
function uploadcsvModule(){
var data = fs.readFileSync( '/home/limitless/Downloads/orders_sample.csv', { encoding : 'utf8'});
var importOptions = {
delimiter : ',', // optional
quote : '"' // optional
},ExportOptions = {
delimiter : ",",
wrap : false
}
var myobj = csvjson.toSchemaObject(data, importOptions)
var exportArr = [], importArr = [];
myobj.forEach(d=>{
if(d.orderId==undefined || d.orderId=='') {
exportArr.push(d)
} else {
importArr.push(d)
}
})
var csv = csvjson.toCSV(exportArr, ExportOptions);
MongoClient.connect(mongoDSN, function(error, db) {
collection = db.collection("orders")
collection.insertMany(importArr, function(err,result){
fs.writeFile('/home/limitless/Downloads/orders_sample1.csv', csv, { encoding : 'utf8'});
db.close();
});
})
}
uploadcsvModule()
SELECT Customers.*

When using “NOT IN”, the query performs nested full table scans, whereas for “NOT EXISTS”, the query can use an index within the sub-query.
In my case, Server had lower version framework than your application. installed latest version framework and it fixed this issue.

If it was mine I'd wrap the choruses and verses in XML elements as well.
In my case following commands worked for me:
sudo npm cache clean --force
sudo npm install -g npm
sudo apt install libssl1.0-dev
sudo apt install nodejs-dev
sudo apt install node-gyp
sudo apt install npm
After that if you are facing "Cannot find module 'bcrypt' then for that you can resolve this one with below commands:
npm install node-gyp -g
npm install bcrypt -g
npm install bcrypt --save
Hope it will work for you as well.
At each point in these instructions, check to see if the problem is fixed. If so, great! Otherwise, continue.

I had to get rid of the NULL values before using the command recommended by Andy above. An example:
df = pd.DataFrame(index = [0, 1, 2], columns=['first', 'second', 'third'])
df.ix[:, 'first'] = 'myword'
df.ix[0, 'second'] = 'myword'
df.ix[2, 'second'] = 'myword'
df.ix[1, 'third'] = 'myword'
df
first second third
0 myword myword NaN
1 myword NaN myword
2 myword myword NaN
Now running the command:
~df["second"].str.contains(word)
I get the following error:
TypeError: bad operand type for unary ~: 'float'
I got rid of the NULL values using dropna() or fillna() first and retried the command with no problem.
Try creating a shell script like the one below:
#!/bin/bash
mysql --user=[username] --password=[password] --database=[db name] --execute="DELETE FROM tbl_message WHERE DATEDIFF( NOW( ) , timestamp ) >=7"
You can then add this to the cron
You could do the following:
DecimalFormatSymbols d = DecimalFormatSymbols.getInstance(Locale.getDefault());
input.setFilters(new InputFilter[] { new DecimalDigitsInputFilter(5, 2) });
input.setKeyListener(DigitsKeyListener.getInstance("0123456789" + d.getDecimalSeparator()));
And then you could use an input filter:
public class DecimalDigitsInputFilter implements InputFilter {
Pattern mPattern;
public DecimalDigitsInputFilter(int digitsBeforeZero, int digitsAfterZero) {
DecimalFormatSymbols d = new DecimalFormatSymbols(Locale.getDefault());
String s = "\\" + d.getDecimalSeparator();
mPattern = Pattern.compile("[0-9]{0," + (digitsBeforeZero - 1) + "}+((" + s + "[0-9]{0," + (digitsAfterZero - 1) + "})?)||(" + s + ")?");
}
@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
Matcher matcher = mPattern.matcher(dest);
if (!matcher.matches())
return "";
return null;
}
}

The problem that I had with the change
handler was that it triggered on every keypress that I scrolled up and down the <select>
.
I wanted to get the event for whenever an option was clicked or when enter
was pressed on the desired option. This is how I ended up doing it:
let blockChange = false;
$element.keydown(function (e) {
const keycode = (e.keyCode ? e.keyCode : e.which);
// prevents select opening when enter is pressed
if (keycode === 13) {
e.preventDefault();
}
// lets the change event know that these keypresses are to be ignored
if([38, 40].indexOf(keycode) > -1){
blockChange = true;
}
});
$element.keyup(function(e) {
const keycode = (e.keyCode ? e.keyCode : e.which);
// handle enter press
if(keycode === 13) {
doSomething();
}
});
$element.change(function(e) {
// this effective handles the click only as preventDefault was used on enter
if(!blockChange) {
doSomething();
}
blockChange = false;
});
You can build random ascii characters like:
import random
print chr(random.randint(0,255))
And then build up a longer string like:
len = 50
print ''.join( [chr(random.randint(0,255)) for i in xrange(0,len)] )
on Windows F9 to run single line
Select the lines which you want to run on console and press F9 button for multi line
You have to use a custom parsing string. I also suggest to include the invariant culture to identify that this format does not relate to any culture. Plus, it will prevent a warning in some code analysis tools.

With SQL server you can just use a CTE instead of IF/THEN logic to make it easy to map from your existing queries and change the number of involved queries;
WITH cte AS (
SELECT product,price,1 a FROM table1 WHERE project=1 UNION ALL
SELECT product,price,2 a FROM table1 WHERE customer=2 UNION ALL
SELECT product,price,3 a FROM table1 WHERE company=3
)
SELECT TOP 1 WITH TIES product,price FROM cte ORDER BY a;
Alternately, you can combine it all into one SELECT
to simplify it for the optimizer;
SELECT TOP 1 WITH TIES product,price FROM table1
WHERE project=1 OR customer=2 OR company=3
ORDER BY CASE WHEN project=1 THEN 1
WHEN customer=2 THEN 2
WHEN company=3 THEN 3 END;

The difference between an operating system and a kernel:
The kernel is a part of an operating system. The operating system is the software package that communicates directly to the hardware and our application. The kernel is the lowest level of the operating system. The kernel is the main part of the operating system and is responsible for translating the command into something that can be understood by the computer. The main functions of the kernel are:
If you use cmd
sudo chown -R $USER:www-data storage
sudo chown -R $USER:www-data bootstrap/cache
If you use GUI
First go to the project and right click on the storage and check the properties and go to the Permissions tab
Change the permissions using below code
sudo chmod -R 777 storage
Then your file properties may be
Then check your settings and execute laravel command it will work :)
As far as I know, shouldOverrideUrlLoading is not called for images but rather for hyperlinks... I think the appropriate method is
@Override
public void onLoadResource(WebView view, String url)
This method is called for every resource (image, styleesheet, script) that's loaded by the webview, but since it's a void, I haven't found a way to change that url and replace it so that it loads a local resource ...
No, there is no better way; yours is canonical.
It is a Bootstrap defined HTML5 data attribute. It binds a button to an event.
Apparently, org.json.simple.JSONArray
implements a raw Iterator. This means that each element is considered to be an Object
. You can try to cast:
for(Object o: arr){
if ( o instanceof JSONObject ) {
parse((JSONObject)o);
}
}
This is how things were done back in Java 1.4 and earlier.
Try with the following code
View titleView = getWindow().findViewById(android.R.id.title);
if (titleView != null) {
ViewParent parent = titleView.getParent();
if (parent != null && (parent instanceof View)) {
View parentView = (View)parent;
parentView.setBackgroundColor(Color.RED);
}
}

There are a lot of solutions out there. Here is a link to the apache wiki which deals with this issue directly.

RewriteEngine On
# This will enable the Rewrite capabilities
RewriteCond %{HTTPS} !=on
# This checks to make sure the connection is not already HTTPS
RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
# This rule will redirect users from their original location, to the same location but using HTTPS.

I recommend you to try Netbeans Profiler.It has rich set of tools for real time analysis. Tools from IbM are worth a try for offline analysis
Note for MySQL 8 it's different
You need to do it in two steps:
CREATE USER 'readonly_user'@'localhost' IDENTIFIED BY 'some_strong_password';
GRANT SELECT, SHOW VIEW ON *.* TO 'readonly_user'@'localhost';
flush privileges;
All you have to do is make a function inside an alias:
$ alias mkcd='_mkcd(){ mkdir "$1"; cd "$1";}; _mkcd'
^ * ^ ^ ^ ^ ^
You must put double quotes around "$1" because single quotes will not work. This is because clashing the quotes at the places marked with arrows confuses the system. Also, a space at the place marked with a star is needed for the function.
I feel like the answer provided by static_rtti is hacky in some sense. I don't know if this was available earlier, but Git tools now provide credential storage.
Cache Mode
$ git config --global credential.helper cache
Use the “cache” mode to keep credentials in memory for a certain period of time. None of the passwords are ever stored on disk, and they are purged from the cache after 15 minutes.
Store Mode
$ git config --global credential.helper 'store --file ~/.my-credentials'
Use the “store” mode to save the credentials to a plain-text file on disk, and they never expire.
I personally used the store mode. I deleted my repository, cloned it, and then had to enter my credentials once.

I'm not sure this is a right way but I solved it by adding display: inline-block;
to the wrapper div.

min-width: 800px;
}
.content{
text-align: justify;
float: right;
width: 90%;

float: left;
width: 10%;
}
As for me it was enough to copy all property fields from the base class to the parent like this:
using System.Reflection;
public static ChildClass Clone(BaseClass b)
{
ChildClass p = new ChildClass(...);
// Getting properties of base class
PropertyInfo[] properties = typeof(BaseClass).GetProperties();
// Copy all properties to parent class
foreach (PropertyInfo pi in properties)
{
if (pi.CanWrite)
pi.SetValue(p, pi.GetValue(b, null), null);
}
return p;
}

Be aware that Count() ignores null values, so if you need to allow for null as its own distinct value you can do something tricky like:
select count(distinct my_col)
+ count(distinct Case when my_col is null then 1 else null end)
from my_table

The problem you have is related to TCP streaming nature.
The fact that you sent 100 Bytes (for example) from the server doesn't mean you will read 100 Bytes in the client the first time you read. Maybe the bytes sent from the server arrive in several TCP segments to the client.
You need to implement a loop in which you read until the whole message was received.
Let me provide an example with DataInputStream
instead of BufferedinputStream
. Something very simple to give you just an example.
Let's suppose you know beforehand the server is to send 100 Bytes of data.
In client you need to write:
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
while(!end)
{
int bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length == 100)
{
end = true;
}
}
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
Now, typically the data size sent by one node (the server here) is not known beforehand. Then you need to define your own small protocol for the communication between server and client (or any two nodes) communicating with TCP.
The most common and simple is to define TLV: Type, Length, Value. So you define that every message sent form server to client comes with:
So you know you have to receive a minimum of 2 Bytes and with the second Byte you know how many following Bytes you need to read.
This is just a suggestion of a possible protocol. You could also get rid of "Type".
So it would be something like:
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
int bytesRead = 0;
messageByte[0] = in.readByte();
messageByte[1] = in.readByte();
int bytesToRead = messageByte[1];
while(!end)
{
bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length == bytesToRead )
{
end = true;
}
}
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
The following code compiles and looks better. It assumes the first two bytes providing the length arrive in binary format, in network endianship (big endian). No focus on different encoding types for the rest of the message.
import java.nio.ByteBuffer;
import java.io.DataInputStream;
import java.net.ServerSocket;
import java.net.Socket;
class Test
{
public static void main(String[] args)
{
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
Socket clientSocket;
ServerSocket server;
server = new ServerSocket(30501, 100);
clientSocket = server.accept();
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
int bytesRead = 0;
messageByte[0] = in.readByte();
messageByte[1] = in.readByte();
ByteBuffer byteBuffer = ByteBuffer.wrap(messageByte, 0, 2);
int bytesToRead = byteBuffer.getShort();
System.out.println("About to read " + bytesToRead + " octets");
//The following code shows in detail how to read from a TCP socket
while(!end)
{
bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length() == bytesToRead )
{
end = true;
}
}
//All the code in the loop can be replaced by these two lines
//in.readFully(messageByte, 0, bytesToRead);
//dataString = new String(messageByte, 0, bytesToRead);
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
android:versionCode — An integer value that represents the version of the application code, relative to other versions.
The value is an integer so that other applications can programmatically evaluate it, for example to check an upgrade or downgrade relationship. You can set the value to any integer you want, however you should make sure that each successive release of your application uses a greater value. The system does not enforce this behavior, but increasing the value with successive releases is normative.
android:versionName — A string value that represents the release version of the application code, as it should be shown to users.
The value is a string so that you can describe the application version as a .. string, or as any other type of absolute or relative version identifier.
As with android:versionCode, the system does not use this value for any internal purpose, other than to enable applications to display it to users. Publishing services may also extract the android:versionName value for display to users.
Typically, you would release the first version of your application with versionCode set to 1, then monotonically increase the value with each release, regardless whether the release constitutes a major or minor release. This means that the android:versionCode value does not necessarily have a strong resemblance to the application release version that is visible to the user (see android:versionName, below). Applications and publishing services should not display this version value to users.
There isn't one built in, but it's simple to roll your own, as demonstrated here:
import operator
def prod(factors):
return reduce(operator.mul, factors, 1)

Which Python module is suitable for data manipulation in a list?
I'm using windows OS, I tried all solutions above and none of them work.
Finally, I install Tesseract-OCR on D drive(Where I run my python script from) instead of C drive and it works.
So, if you are using windows, run your python script in the same drive as your Tesseract-OCR.
For me I had a special characters in my password field, and I put it like $mail->Password = " por$ch3" which work for gmail smpt server but not for other; so I just changed double quotes to single quotes and it works for me. $mail->Password = ' por$ch3';
//controller You can use this way
public ActionResult Index()
{
List<Fund> fundList = db.Funds.ToList();
ViewBag.Funds = fundList;
return View();
}
<--View ; You can use this way html-->
@foreach (var item in (List<Fund>)ViewBag.Funds)
{
<p>@item.firtname</p>

I was in a situation where Linq binding was not available and had to expand lambda explicitly. It resulted in a simple function:
public static T KeyByValue<T, W>(this Dictionary<T, W> dict, W val)
{
T key = default;
foreach (KeyValuePair<T, W> pair in dict)
{
if (EqualityComparer<W>.Default.Equals(pair.Value, val))
{
key = pair.Key;
break;
}
}
return key;
}
Call it like follows:
public static void Main()
{
Dictionary<string, string> dict = new Dictionary<string, string>()
{
{"1", "one"},
{"2", "two"},
{"3", "three"}
};
string key = KeyByValue(dict, "two");
Console.WriteLine("Key: " + key);
}
Works on .NET 2.0 and in other limited environments.
Another cause of this issue is when the Take tail-log backup before restore
"Options" setting is enabled.
On the "Options" tab, Disable/uncheck Take tail-log backup before restore
before restoring to a database that doesn't yet exist.
You need to specify the minimum width of the field.
String.format("%" + numberOfSpaces + "s", "");
Why do you want to generate a String of spaces of a certain length.
If you want a column of this length with values then you can do:
String.format("%" + numberOfSpaces + "s", "Hello");
which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.
When at the "Add resource folder", Build Path -> Configure Build Path -> Source (Tab) -> Add Folder -> Create new Folder
add "my-resource.txt" file inside the new folder. Then in your code:
InputStream res =
Main.class.getResourceAsStream("/my-resource.txt");
BufferedReader reader =
new BufferedReader(new InputStreamReader(res));
String line = null;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
reader.close();
There are many ways to do this, however the ones I prefer is given below
seq
Synopsis from
man seq
$ seq [-w] [-f format] [-s string] [-t string] [first [incr]] last
Syntax
Full command
seq first incr last
Example:
$ seq 1 2 10
1 3 5 7 9
Only with first and last:
$ seq 1 5
1 2 3 4 5
Only with last:
$ seq 5
1 2 3 4 5
{first..last..incr}
Here first and last are mandatory and incr is optional
Using just first and last
$ echo {1..5}
1 2 3 4 5
Using incr
$ echo {1..10..2}
1 3 5 7 9
You can use this even for characters like below
$ echo {a..z}
a b c d e f g h i j k l m n o p q r s t u v w x y z
ECMA Script 6 Version
If you are in an environment which supports ECMA Script 6's Set
, then you can use Array.prototype.some
and a Set
object, like this
let seen = new Set();
var hasDuplicates = values.some(function(currentObject) {
return seen.size === seen.add(currentObject.name).size;
});
Here, we insert each and every object's name
into the Set
and we check if the size
before and after adding are the same. This works because Set.size
returns a number based on unique data (set only adds entries if the data is unique). If/when you have duplicate names, the size won't increase (because the data won't be unique) which means that we would have already seen the current name and it will return true.
ECMA Script 5 Version
If you don't have Set
support, then you can use a normal JavaScript object itself, like this
var seen = {};
var hasDuplicates = values.some(function(currentObject) {
if (seen.hasOwnProperty(currentObject.name)) {
// Current name is already seen
return true;
}
// Current name is being seen for the first time
return (seen[currentObject.name] = false);
});
The same can be written succinctly, like this
var seen = {};
var hasDuplicates = values.some(function (currentObject) {
return seen.hasOwnProperty(currentObject.name)
|| (seen[currentObject.name] = false);
});
Note: In both the cases, we use Array.prototype.some
because it will short-circuit. The moment it gets a truthy value from the function, it will return true
immediately, it will not process rest of the elements.
Zambri's answer found here is the best.
File.open("out.txt", '<OPTION>') {|f| f.write("write your stuff here") }
where your options for <OPTION>
are:
r
- Read only. The file must exist.
w
- Create an empty file for writing.
a
- Append to a file.The file is created if it does not exist.
r+
- Open a file for update both reading and writing. The file must exist.
w+
- Create an empty file for both reading and writing.
a+
- Open a file for reading and appending. The file is created if it does not exist.
In your case, w
is preferable.
Something like this happened when I changed the build target to 3.2. After digging around I found that a had named the jar lib folder "lib" instead of "libs". I just renamed it to libs and updated the references on the Java build path and everything was working again. Maybe this will help someone...
I actually came across something like this not too long ago... check it out over on msdn (see the first answer)
in summary:
.cer - certificate stored in the X.509 standard format. This certificate contains information about the certificate's owner... along with public and private keys.
.pvk - files are used to store private keys for code signing. You can also create a certificate based on .pvk private key file.
.pfx - stands for personal exchange format. It is used to exchange public and private objects in a single file. A pfx file can be created from .cer file. Can also be used to create a Software Publisher Certificate.
I summarized the info from the page based on the suggestion from the comments.
Same everyday problem.
I just created a simple vc project to solve this problem.
It copies the file as Base64 encoded data directly to the clipboard, and then this can be pasted into the PuTTY console and decoded on the remote side.
This solution is for relatively small files (relative to the connection speed to your remote console).
Download clip_b64.exe
and place it in the SendTo folder (or a .lnk
shortcut to it). To open this folder, in the address bar of the explorer, enter shell:sendto
or %appdata%\Microsoft\Windows\SendTo
.
You may need to install VC 2017 redist to run it, or use the statically linked clip_b64s.exe
execution.
In the File Explorer, right-click the file you are transferring to open the context menu, then go to the "Send To" section and select Clip_B64
from the list.
Run the shell command base64 -d > file-name-you-want
and right-click in the console (or press Shift + Insert
) to place the clipboard content in it, and then press Ctrl + D
to finish.
voila
VM Player runs a virtual instance, but can't create the vm. [Edit: Now it can.] Workstation allows for the creation and administration of virtual machines. If you have a second machine, you can create the vm on one and run it with the player the other machine. I bought Workstation and I use it setup testing vms that the player runs. Hope this explains it for you.
Edit: According to the FAQ:
VMware Workstation is much more advanced and comes with powerful features including snapshots, cloning, remote connections to vSphere, sharing VMs, advanced Virtual Machines settings and much more. Workstation is designed to be used by technical professionals such as developers, quality assurance engineers, systems engineers, IT administrators, technical support representatives, trainers, etc.

If you don't want to use jQuery mobile
as like me. You can use Hammer.js
It's mostly like jQuery Mobile
without unnecessary code.

});
Hammer(myCarousel).on("swiperight", function(){
$(this).carousel('prev');
});
});
Two steps worked for me:

Contrary to some of the other answers here, I say that you can use tabs however you want. vim was designed to be versatile and customizable, rather than forcing you to work according to predefined parameters. We all know how us programmers love to impose our "ethics" on everyone else, so this achievement is certainly a primary feature.
<C-w>gf
is the tab equivalent of buffers' gf
command. <C-PageUp>
and <C-PageDown>
will switch between tabs. (In Byobu, these two commands never work for me, but they work outside of Byobu/tmux. Alternatives are gt
and gT
.) <C-w>T
will move the current window to a new tab page.
If you'd prefer that vim use an existing tab if possible, rather than creating a duplicate tab, add :set switchbuf=usetab
to your .vimrc file. You can add newtab
to the list (:set switchbuf=usetab,newtab
) to force QuickFix commands that display compile errors to open in separate tabs. I prefer split
instead, which opens the compile errors in a split window.
If you have mouse support enabled with :set mouse=a
, you can interact with the tabs by clicking on them. There's also a +
button by default that will create a new tab.
For the documentation on tabs, type :help tab-page
in normal mode. (After you do that, you can practice moving a window to a tab using <C-w>T
.) There's a long list of commands. Some of the window commands have to do with tabs, so you might want to look at that documentation as well via :help windows
.
Addition: 2013-12-19
To open multiple files in vim with each file in a separate tab, use vim -p file1 file2 ...
. If you're like me and always forget to add -p
, you can add it at the end, as vim follows the normal command line option parsing rules. Alternatively, you can add a bash alias mapping vim
to vim -p
.

Here's a utility class I use to convert the newer java.time

return Date.from(localDateTime.atZone(ZoneId.systemDefault()).toInstant());
}
public static LocalDate asLocalDate(Date date) {
return Instant.ofEpochMilli(date.getTime()).atZone(ZoneId.systemDefault()).toLocalDate();
}
public static LocalDateTime asLocalDateTime(Date date) {
return Instant.ofEpochMilli(date.getTime()).atZone(ZoneId.systemDefault()).toLocalDateTime();
}
}

I had such problem. In my case problem was in data - my column 'information' contained 1 unique value and it caused error
UPDATE: to correct work 'pivot' pairs (id_user,information) cannot have duplicates
It works:
df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5],
'information':['phon','phon','phone','phone1','phone','phone1','phone'],
'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')
it doesn't work:
df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5],
'information':['phone','phone','phone','phone','phone','phone','phone'],
'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')

This script copies filename.ext to filename-date.ext, there is another that moves filename.ext to filename-date.ext, you can download them from here. Hope you find them useful!!
You don't necessarily need Ajax for this. Just an <a>
link is enough if you set the content-disposition
to attachment
in the server side code. This way the parent page will just stay open, if that was your major concern (why would you unnecessarily have chosen Ajax for this otherwise?). Besides, there is no way to handle this nicely acynchronously. PDF is not character data. It's binary data. You can't do stuff like $(element).load()
. You want to use completely new request for this. For that <a href="pdfservlet/filename.pdf">pdf</a>
is perfectly suitable.
To assist you more with the server side code, you'll need to tell more about the language used and post an excerpt of the code attempts.
You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).
One option I've been looking into is to handle the history yourself in JavaScript and use the window.history
object as a carrier of sorts.
Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState
. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.
var myHistory = [];
function pageLoad() {
window.history.pushState(myHistory, "<name>", "<url>");
//Load page data.
}
Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState
to keep the browser out of the loop.
function nav_to_details() {
myHistory.push("page_im_on_now");
window.history.replaceState(myHistory, "<name>", "<url>");
//Load page data.
}
When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.
function on_popState() {
// Note that some browsers fire popState on initial load,
// so you should check your state object and handle things accordingly.
// (I did not do that in these examples!)
if (myHistory.length > 0) {
var pg = myHistory.pop();
window.history.pushState(myHistory, "<name>", "<url>");
//Load page data for "pg".
} else {
//No "history" - let them exit or keep them in the app.
}
}
The user will never be able to navigate forward using their browser buttons because they are always on the newest page.
From the browser's perspective, every time they go "back", they've immediately pushed forward again.
From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).
From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).
If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...
var myHistory = [];
function pageLoad() {
// When the user first hits your page...
// Check the state to see what's going on.
if (window.history.state === null) {
// If the state is null, this is a NEW navigation,
// the user has navigated to your page directly (not using back/forward).
// First we establish a "back" page to catch backward navigation.
window.history.replaceState(
{ isBackPage: true },
"<back>",
"<back>"
);
// Then push an "app" page on top of that - this is where the user will sit.
// (As browsers vary, it might be safer to put this in a short setTimeout).
window.history.pushState(
{ isBackPage: false },
"<name>",
"<url>"
);
// We also need to start our history tracking.
myHistory.push("<whatever>");
return;
}
// If the state is NOT null, then the user is returning to our app via history navigation.
// (Load up the page based on the last entry of myHistory here)
if (window.history.state.isBackPage) {
// If the user came into our app via the back page,
// you can either push them forward one more step or just use pushState as above.
window.history.go(1);
// or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
}
setTimeout(function() {
// Add our popstate event listener - doing it here should remove
// the issue of dealing with the browser firing it on initial page load.
window.addEventListener("popstate", on_popstate);
}, 100);

I had same issue with my WPF RSS reader, I originally went with Awesomium (I think version 1.6) Awesomium is great. You get a lot of control for caching (images and HTML content), JavaScript execution, intercepting downloads and so forth. It's also super fast. The process isolation means when browser crashes it does not crash the app.
But it's also heavy, even release build adds about 10-15mb (can't remember exact number) and hence a slight start-up penalty. I then realized, only problem I had with IE browser control was that it would throw the JavaScript errors every now and again. But that was fixed with the following snippet.
I hardly used my app on XP or Vista but on Win 7 and above it never crashed (at least not because I used IE browser control)
IOleServiceProvider sp = browser.Document as IOleServiceProvider;
if (sp != null)
{
IID_IWebBrowserApp = new Guid("0002DF05-0000-0000-C000-000000000046");
Guid IID_IWebBrowser2 = new Guid("D30C1661-CDAF-11d0-8A3E-00C04FC9E26E");
webBrowser;
sp.QueryService(ref IID_IWebBrowserApp, ref IID_IWebBrowser2, out webBrowser);
if (webBrowser != null)
{
webBrowser.GetType().InvokeMember("Silent",
BindingFlags.Instance | BindingFlags.Public | BindingFlags.PutDispProperty, null, webBrowser, new object[] { silent });
}
}
loadRequest: is an instance method, not a class method. You should be attempting to call this method with an instance of UIWebview as the receiver, not the class itself.
webviewInstance.loadRequest(NSURLRequest(URL: NSURL(string: "google.ca")!))
However, as @radex correctly points out below, you can also take advantage of currying to call the function like this:
UIWebView.loadRequest(webviewInstance)(NSURLRequest(URL: NSURL(string: "google.ca")!))
Swift 5
webviewInstance.load(NSURLRequest(url: NSURL(string: "google.ca")! as URL) as URLRequest)
Put it in a separate, custom header.
Overloading the standard HTTP headers is probably going to cause more confusion than it's worth, and will violate the principle of least surprise. It might also lead to interoperability problems for your API client programmers who want to use off-the-shelf tool kits that can only deal with the standard form of typical HTTP headers (such as Authorization
).
Try this if using spark 2.0+
For non-hdfs file:
df = spark.read.csv("file:///csvfile.csv")
For hdfs file:
df = spark.read.csv("hdfs:///csvfile.csv")
For hdfs file (with different delimiter than comma:
df = spark.read.option("delimiter","|")csv("hdfs:///csvfile.csv")
Note:- this work for any delimited file. Just use option(“delimiter”,) to change value.
Hope this is helpful.
Check out array_merge()
.
$array3 = array_merge($array1, $array2);
You need just to reverse your date digit and change -
with ,
:
new Date(2012,01,26).getTime(); // 02 becomes 01 because getMonth() method returns the month (from 0 to 11)
In your case:
var myDate="26-02-2012";
myDate=myDate.split("-");
new Date(parseInt(myDate[2], 10), parseInt(myDate[1], 10) - 1 , parseInt(myDate[0]), 10).getTime();
P.S. UK locale does not matter here.
You can write the where
clause as:
where (case when (:stateCode = '') then (1)
when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
else 0)
end) = 1;
Alternatively, remove the case
entirely:
where (:stateCode = '') or
((:stateCode != '') and vw.state_cd in (:stateCode));
Or, even better:
where (:stateCode = '') or vw.state_cd in (:stateCode)
Using jQuery ...

I have also received this error when developing automatic tests for components. In this context the following import should be done:
import { RouterTestingModule } from "@angular/router/testing";
const testBedConfiguration = {
imports: [SharedModule,
BrowserAnimationsModule,
RouterTestingModule.withRoutes([]),
],
try this
Package manager console
Install-Package System.Net.Http.Formatting.Extension -Version 5.2.3
and then add by using add reference .
This is the problem to start with:
Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("EST"));
The 3-letter abbreviations should be wholeheartedly avoided in favour of TZDB zone IDs. EST is Eastern Standard Time - and Standard time never observes DST; it's not really a full time zone name. It's the name used for part of a time zone. (Unfortunately I haven't come across a good term for this "half time zone" concept.)
You want a full time zone name. For example, America/New_York
is in the Eastern time zone:
TimeZone zone = TimeZone.getTimeZone("America/New_York");
DateFormat format = DateFormat.getDateTimeInstance();
format.setTimeZone(zone);
System.out.println(format.format(new Date()));
There are several tools which can import Excel to SQL Server.
I am using DbTransfer (http://www.dbtransfer.com/Products/DbTransfer) to do the job. It's primarily focused on transfering data between databases and excel, xml, etc...
I have tried the openrowset method and the SQL Server Import / Export Assitant before. But I found these methods to be unnecessary complicated and error prone in constrast to doing it with one of the available dedicated tools.
I would rather use plt.clf()
after every plt.show()
to just clear the current figure instead of closing and reopening it, keeping the window size and giving you a better performance and much better memory usage.
Similarly, you could do plt.cla()
to just clear the current axes.
To clear a specific axes, useful when you have multiple axes within one figure, you could do for example:
fig, axes = plt.subplots(nrows=2, ncols=2)
axes[0, 1].clear()
Here is the code: replace package_name by your specific package name.
Intent i = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
i.addCategory(Intent.CATEGORY_DEFAULT);
i.setData(Uri.parse("package:package_name"));
startActivity(i);
If units used are SP, not DP, and you want to override system font scaling, all you do is override one method in activity - see this post.
resources.updateConfiguration is deprecated and buggy (on Oreo I had issues with formatted text).
You can also install Git Credential Manager for Windows to save Git passwords in Windows credentials manager instead of _netrc
. This is a more secure way to store passwords.
Here's a reusable way of doing it (it's typescript but you can adapt it to js):
export function waitFor<T>(signal: Observable<any>) {
return (source: Observable<T>) =>
new Observable<T>(observer =>
signal.pipe(first())
.subscribe(_ =>
source.subscribe(observer)
)
);
}
and you can use it like any operator:
var two = someOtherObservable.pipe(waitFor(one), take(1));
It's basically an operator that defers the subscribe on the source observable until the signal observable emits the first event.
finalName is created as:
<build>
<finalName>${project.artifactId}-${project.version}</finalName>
</build>
One of the solutions is to add own property:
<properties>
<finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
<finalName>${finalName}</finalName>
</build>
And now try:
mvn -DfinalName=build clean package
There's no isNumeric()
type of function, but you could add your own:
function isNumeric(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
NOTE: Since parseInt()
is not a proper way to check for numeric it should NOT be used.
Here is what I have done to make the right scroll bar work. The only thing needed to be considered is when using 'direction: rtl' and whole table also need to be changed. Hopefully this gives you an idea how to do it.
Example:
<table dir='rtl'><tr><td>Display Last</td><td>Display Second</td><td>Display First</td></table>
Check this: JSFiddle
To ensure that JQuery isn't caching the results, on your ajax methods, put the following:
$.ajax({
cache: false
//rest of your ajax setup
});
Or to prevent caching in MVC, we created our own attribute, you could do the same. Here's our code:
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public sealed class NoCacheAttribute : ActionFilterAttribute
{
public override void OnResultExecuting(ResultExecutingContext filterContext)
{
filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
filterContext.HttpContext.Response.Cache.SetNoStore();
base.OnResultExecuting(filterContext);
}
}
Then just decorate your controller with [NoCache]
. OR to do it for all you could just put the attribute on the class of the base class that you inherit your controllers from (if you have one) like we have here:
[NoCache]
public class ControllerBase : Controller, IControllerBase
You can also decorate some of the actions with this attribute if you need them to be non-cacheable, instead of decorating the whole controller.
If your class or action didn't have NoCache
when it was rendered in your browser and you want to check it's working, remember that after compiling the changes you need to do a "hard refresh" (Ctrl+F5) in your browser. Until you do so, your browser will keep the old cached version, and won't refresh it with a "normal refresh" (F5).
Long time ago, all browser providers were making JavaScript engines for their browsers and only they and god knew what was happening inside this. One beautiful day, ECMA international came and said: let's make engines based on common standard, let's make something general to make life more easy and fun, and they made that standard. Since all browser providers make their JavaScript engines based on ECMAScript core (standard).
For example, Google Chrome uses V8 engine and this is open source. You can download it and see how C++ program translates a command 'print' of JavaScript to machine code.
Internet Explorer uses JScript (Chakra) engine for their browser and others do so and they all uses common core.
Utilities.sleep(milliseconds) creates a 'pause' in program execution, meaning it does nothing during the number of milliseconds you ask. It surely slows down your whole process and you shouldn't use it between function calls. There are a few exceptions though, at least that one that I know : in SpreadsheetApp when you want to remove a number of sheets you can add a few hundreds of millisecs between each deletion to allow for normal script execution (but this is a workaround for a known issue with this specific method). I did have to use it also when creating many sheets in a spreadsheet to avoid the Browser needing to be 'refreshed' after execution.
Here is an example :
function delsheets(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var numbofsheet=ss.getNumSheets();// check how many sheets in the spreadsheet
for (pa=numbofsheet-1;pa>0;--pa){
ss.setActiveSheet(ss.getSheets()[pa]);
var newSheet = ss.deleteActiveSheet(); // delete sheets begining with the last one
Utilities.sleep(200);// pause in the loop for 200 milliseconds
}
ss.setActiveSheet(ss.getSheets()[0]);// return to first sheet as active sheet (useful in 'list' function)
}
To avoid problems of side effects after changing env
, especially using multiple nodes, it is better to set a temporary context.
One safe way to alter the environment is:
withEnv(['MYTOOL_HOME=/usr/local/mytool']) {
sh '$MYTOOL_HOME/bin/start'
}
This approach does not poison the env after the command execution.

For doing "normal" hash table lookups on basically any kind of data - this one by Paul Hsieh is the best I've ever used.
http://www.azillionmonkeys.com/qed/hash.html
If you care about cryptographically secure or anything else more advanced, then YMMV. If you just want a kick ass general purpose hash function for a hash table lookup, then this is what you're looking for.
list is mutable
Change
last_list=last_list.append(p.last_name)
to
last_list.append(p.last_name)
will work
1.If I have something like Foo o = new Foo(); inside the method, does that mean that each time the timer ticks, I'm creating a new object and a new reference to that object?
Yes.
2.If I have string foo = null and then I just put something temporal in foo, is it the same as above?
If you are asking if the behavior is the same then yes.
3.Does the garbage collector ever delete the object and the reference or objects are continually created and stay in memory?
The memory used by those objects is most certainly collected after the references are deemed to be unused.
4.If I just declare Foo o; and not point it to any instance, isn't that disposed when the method ends?
No, since no object was created then there is no object to collect (dispose is not the right word).
5.If I want to ensure that everything is deleted, what is the best way of doing it
If the object's class implements IDisposable
then you certainly want to greedily call Dispose
as soon as possible. The using
keyword makes this easier because it calls Dispose
automatically in an exception-safe way.
Other than that there really is nothing else you need to do except to stop using the object. If the reference is a local variable then when it goes out of scope it will be eligible for collection.1 If it is a class level variable then you may need to assign null
to it to make it eligible before the containing class is eligible.
1This is technically incorrect (or at least a little misleading). An object can be eligible for collection long before it goes out of scope. The CLR is optimized to collect memory when it detects that a reference is no longer used. In extreme cases the CLR can collect an object even while one of its methods is still executing!
Update:
Here is an example that demonstrates that the GC will collect objects even though they may still be in-scope. You have to compile a Release build and run this outside of the debugger.
static void Main(string[] args)
{
Console.WriteLine("Before allocation");
var bo = new BigObject();
Console.WriteLine("After allocation");
bo.SomeMethod();
Console.ReadLine();
// The object is technically in-scope here which means it must still be rooted.
}
private class BigObject
{
private byte[] LotsOfMemory = new byte[Int32.MaxValue / 4];
public BigObject()
{
Console.WriteLine("BigObject()");
}
~BigObject()
{
Console.WriteLine("~BigObject()");
}
public void SomeMethod()
{
Console.WriteLine("Begin SomeMethod");
GC.Collect();
GC.WaitForPendingFinalizers();
Console.WriteLine("End SomeMethod");
}
}
On my machine the finalizer is run while SomeMethod
is still executing!
You could use the STRING_SPLIT function in SQL Server. You can check the documentation here.
DECLARE @YourListOfIds VARCHAR(1000) -- Or VARCHAR(MAX) depending on what you need
SET @YourListOfIds = '1,2,3,4,5,6,7,8'
SELECT * FROM YourTable
WHERE Id IN(SELECT CAST(Value AS INT) FROM STRING_SPLIT(@YourListOfIds, ','))
For anyone using Flask-SQLAlchemy, this worked for me
from app import db
from app.models import Purchases
from sqlalchemy.orm import aliased
from sqlalchemy import desc
stmt = Purchases.query.distinct(Purchases.address_id).subquery('purchases')
alias = aliased(Purchases, stmt)
distinct = db.session.query(alias)
distinct.order_by(desc(alias.purchased_at))
As early as possible in your application, require and configure dotenv.
require('dotenv').config()
you can save yourself the .strip() fcn by just slicing off the first and last characters from the string representation of the list (see third line below)
>>> mylist=[1,2,3,4,5,'baloney','alfalfa']
>>> strlist=str(mylist)
['1', ' 2', ' 3', ' 4', ' 5', " 'baloney'", " 'alfalfa'"]
>>> mylistfromstring=(strlist[1:-1].split(', '))
>>> mylistfromstring[3]
'4'
>>> for entry in mylistfromstring:
... print(entry)
... type(entry)
...

<class 'str'>

That is the syntax for Update
statement in SQL, you have to use that syntax otherwise you will get the exception.
command.Text = "UPDATE Student SET Address = @add, City = @cit Where FirstName = @fn AND LastName = @ln";
and then add your parameters accordingly.
command.Parameters.AddWithValue("@ln", lastName);

Put novalidate="novalidate"

.
I'll try and break it down (example from documention)
/*
* The cellForRowAtIndexPath takes for argument the tableView (so if the same object
* is delegate for several tableViews it can identify which one is asking for a cell),
* and an indexPath which determines which row and section the cell is returned for.
*/
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
/*
* This is an important bit, it asks the table view if it has any available cells
* already created which it is not using (if they are offScreen), so that it can
* reuse them (saving the time of alloc/init/load from xib a new cell ).
* The identifier is there to differentiate between different types of cells
* (you can display different types of cells in the same table view)
*/
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyIdentifier"];
/*
* If the cell is nil it means no cell was available for reuse and that we should
* create a new one.
*/
if (cell == nil) {
/*
* Actually create a new cell (with an identifier so that it can be dequeued).
*/
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"MyIdentifier"] autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
/*
* Now that we have a cell we can configure it to display the data corresponding to
* this row/section
*/
NSDictionary *item = (NSDictionary *)[self.content objectAtIndex:indexPath.row];
cell.textLabel.text = [item objectForKey:@"mainTitleKey"];
cell.detailTextLabel.text = [item objectForKey:@"secondaryTitleKey"];
NSString *path = [[NSBundle mainBundle] pathForResource:[item objectForKey:@"imageKey"] ofType:@"png"];
UIImage *theImage = [UIImage imageWithContentsOfFile:path];
cell.imageView.image = theImage;
/* Now that the cell is configured we return it to the table view so that it can display it */
return cell;
}
This is a DataSource
method so it will be called on whichever object has declared itself as the DataSource
of the UITableView
. It is called when the table view actually needs to display the cell onscreen, based on the number of rows and sections (which you specify in other DataSource methods).
Using Xcode 7.3, I spent way too much time trying to figure this out -- none of the answers here or elsewhere did the trick -- and ultimately stumbled into a ridiculously easy solution.
Hope this helps someone.
Just make the top-level layout a ScrollView:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<TableLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:stretchColumns="1">
<!-- everything you already have -->
</TableLayout>
</ScrollView>
I think you can create a simple SQL query:
$sql="select username from user where id in (select id from idtables)";
$query=$this->db->query($sql);
and then you can use it normally.
If you want to remove EVERYTHING :
textarea {
border: none;
background-color: transparent;
resize: none;
outline: none;
}
In Posgresql you could use ~
For example you could search for all rows that have col_a
with any letter in lowercase
select * from your_table where col_a '[a-z]';
You could modify the Regex expression according your needs.
Regards,
This is how I rename keys, especially with data that has been uploaded in a spreadsheet:
function changeKeys($array, $new_keys) {
$newArray = [];
foreach($array as $row) {
$oldKeys = array_keys($row);
$indexedRow = [];
foreach($new_keys as $index => $newKey)
$indexedRow[$newKey] = isset($oldKeys[$index]) ? $row[$oldKeys[$index]] : '';
$newArray[] = $indexedRow;
}
return $newArray;
}

There's display: none
, but I think that might be a bit more than what you're looking for.
One option, that looks like it makes two functions run at the same
time, is using the threading
module (example in this answer).
However, it has a small delay, as an Official Python Documentation
page describes. A better module to try using is multiprocessing
.
Also, there's other Python modules that can be used for asynchronous execution (two pieces of code working at the same time). For some information about them and help to choose one, you can read this Stack Overflow question.
threading
moduleHe might want to know that because of the Global Interpreter Lock
they will not execute at the exact same time even if the machine in
question has multiple CPUs. wiki.python.org/moin/GlobalInterpreterLock
– Jonas Elfström Jun 2 '10 at 11:39
threading
module not workingCPython implementation detail: In CPython, due to the Global Interpreter
Lock, only one thread can execute Python code at once (even though
certain performance-oriented libraries might overcome this limitation).If you want your application to make better use of the computational resources of multi-core machines, you are advised to use multiprocessing or concurrent.futures.ProcessPoolExecutor.
However, threading is still an appropriate model if you
want to run multiple I/O-bound tasks simultaneously.
If you want to retrieve multiple values of attributes from the source above, you can use findAll
and a list comprehension to get everything you need:
import urllib
f = urllib.urlopen("http://58.68.130.147")
s = f.read()
f.close()
from BeautifulSoup import BeautifulStoneSoup
soup = BeautifulStoneSoup(s)
inputTags = soup.findAll(attrs={"name" : "stainfo"})
### You may be able to do findAll("input", attrs={"name" : "stainfo"})
output = [x["stainfo"] for x in inputTags]
print output
### This will print a list of the values.
You can use regex
here:
>>> import re
>>> strs = "foo\tbar\t\tspam"
>>> re.split(r'\t+', strs)
['foo', 'bar', 'spam']
update:
You can use str.rstrip
to get rid of trailing '\t'
and then apply regex.
>>> yas = "yas\t\tbs\tcda\t\t"
>>> re.split(r'\t+', yas.rstrip('\t'))
['yas', 'bs', 'cda']
If the required properties need to set in system then there is no option than -D But if you need those properties while bootstrapping an application then loading properties through the properties files is a best option. It will not require to change build for a single property.
You can use awk just to print the first 'field' if there won't be any spaces (or if there will be, change the separator'.
I put the fields you had above into a file and did this
awk '{ print $1 }' < test.txt
