You could also install the package with pip by using this command:
pip install git+https://github.com/rthalley/dnspython
list( map( lambda x: x[4][0], socket.getaddrinfo( \
'www.example.com.',22,type=socket.SOCK_STREAM)))
gives you a list of the addresses for www.example.com. (ipv4 and ipv6)
The thing is that decimal numbers defaults to double. And since double doesn't fit into float you have to tell explicitely you intentionally define a float. So go with:
float b = 3.6f;
Use this:
((AssemblyFileVersionAttribute)Attribute.GetCustomAttribute(
Assembly.GetExecutingAssembly(),
typeof(AssemblyFileVersionAttribute), false)
).Version;
Or this:
new Version(System.Windows.Forms.Application.ProductVersion);
You can use DateTime.ParseExact()
method.
Converts the specified string representation of a date and time to its DateTime equivalent using the specified format and culture-specific format information. The format of the string representation must match the specified format exactly.
DateTime date = DateTime.ParseExact("04/30/2013 23:00",
"MM/dd/yyyy HH:mm",
CultureInfo.InvariantCulture);
Here is a DEMO
.
hh
is for 12-hour clock from 01 to 12, HH
is for 24-hour clock from 00 to 23.
For more information, check Custom Date and Time Format Strings

Any Python file is a module, its name being the file's base name without the .py
extension. A package is a collection of Python modules: while a module is a single Python file, a package is a directory of Python modules containing an additional __init__.py
file, to distinguish a package from a directory that just happens to contain a bunch of Python scripts. Packages can be nested to any depth, provided that the corresponding directories contain their own __init__.py
file.
The distinction between module and package seems to hold just at the file system level. When you import a module or a package, the corresponding object created by Python is always of type module
. Note, however, when you import a package, only variables/functions/classes in the __init__.py
file of that package are directly visible, not sub-packages or modules. As an example, consider the xml
package in the Python standard library: its xml
directory contains an __init__.py
file and four sub-directories; the sub-directory etree
contains an __init__.py
file and, among others, an ElementTree.py
file. See what happens when you try to interactively import package/modules:
>>> import xml
>>> type(xml)
<type 'module'>
>>> xml.etree.ElementTree
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'etree'
>>> import xml.etree
>>> type(xml.etree)
<type 'module'>
>>> xml.etree.ElementTree
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'ElementTree'
>>> import xml.etree.ElementTree
>>> type(xml.etree.ElementTree)
<type 'module'>
>>> xml.etree.ElementTree.parse
<function parse at 0x00B135B0>
In Python there also are built-in modules, such as sys
, that are written in C, but I don't think you meant to consider those in your question.
Chances are that, if all the answers above didn't work for you, and you are using a request validation, you forgot to put the authorization to true.
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class EquipmentRequest extends FormRequest {
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize() {
/*******************************************************/
return true; /************ THIS VALUE NEEDS TO BE TRUE */
/*******************************************************/
}
/* ... */
}
Try this
new_df = pd.merge(A_df, B_df, how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])

left_on : label or list, or array-like Field names to join on in left DataFrame. Can be a vector or list of vectors of the length of the DataFrame to use a particular vector as the join key instead of columns
right_on : label or list, or array-like Field names to join on in right DataFrame or vector/list of vectors per left_on docs

Have you set the appId property to your current application ID?
www.bitvise.com - sftpc is a good command line client also.
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;

}
typedef long(*f_entrypoint)(long id);

}
enum SN::EntryValues defaultEntryArray[SN::LastEntry];
#define DEFINE_ENTRY_DEFAULT(I, C, L, D) \
defaultEntryArray[I##_##D##_entry] = I##_def_entry;
void LoadDefaultEntries()
{

}
void Initialize()
{
if (!loaded)
{

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"
$criteria = new \Doctrine\Common\Collections\Criteria();
$criteria->where($criteria->expr()->gt('id', 'id'))

I just want to throw this answer in the mix, intended as a reminder that – given the right conditions – you sometimes don't need to overthink the issue at hand. What you want might be achievable with flex: wrap
and max-width
instead of :nth-child
.

flex-wrap: wrap;

Modern answer:
ZoneId zone = ZoneId.systemDefault();
System.out.println(zone);
When I ran this snippet in Australia/Sydney time zone, the output was exactly that:
Australia/Sydney
If you want the summer time (DST) aware time zone name or abbreviation:
DateTimeFormatter longTimeZoneFormatter = DateTimeFormatter.ofPattern("zzzz", Locale.getDefault());
String longTz = ZonedDateTime.now(zone).format(longTimeZoneFormatter);
System.out.println(longTz);
DateTimeFormatter shortTimeZoneFormatter = DateTimeFormatter.ofPattern("zzz", Locale.getDefault());
String shortTz = ZonedDateTime.now(zone).format(shortTimeZoneFormatter);
System.out.println(shortTz);
Eastern Summer Time (New South Wales) EST
The TimeZone
class used in most of the other answers was what we had when the question was asked in 2011, even though it was poorly designed. Today it’s long outdated, and I recommend that instead we use java.time, the modern Java date and time API that came out in 2014.
java.time works nicely on both older and newer Android devices. It just requires at least Java 6.
org.threeten.bp
with subpackages.java.time
was first described.java.time
to Java 6 and 7 (ThreeTen for JSR-310).You can use scriptlets, however, this is not the way to go. Nowdays inline scriplets or JAVA code in your JSP files is considered a bad habit.
You should read up on JSTL a bit more. If the ansokanInfo object is in your request or session scope, printing the object (toString() method) like this: ${ansokanInfo} can give you some base information. ${ansokanInfo.pSystem} should call the object getter method. If this all works, you can use this:
<c:if test="${ ansokanInfo.pSystem == 'NAT'}"> tataa </c:if>
My items have unique id's. I am deleting one by filtering the model with angulars $filter
service:
var myModel = [{id:12345, ...},{},{},...,{}];
...
// working within the item
function doSthWithItem(item){
...
myModel = $filter('filter')(myModel, function(value, index)
{return value.id !== item.id;}
);
}
As id you could also use the $$hashKey property of your model items: $$hashKey:"object:91"
The size
property is what you're after as mentioned. To set both the the orientation and size of your page when printing, you could use the following:
/* ISO Paper Size */
@page {
size: A4 landscape;
}
/* Size in mm */
@page {
size: 100mm 200mm landscape;
}
/* Size in inches */
@page {
size: 4in 6in landscape;
}
Here's a link to the @page documentation.
Even though this does not rely on ICMP on Windows, this implementation works pretty well with the new Duration API
public static Duration ping(String host) {
Instant startTime = Instant.now();
try {
InetAddress address = InetAddress.getByName(host);
if (address.isReachable(1000)) {
return Duration.between(startTime, Instant.now());
}
} catch (IOException e) {
// Host not available, nothing to do here
}
return Duration.ofDays(1);
}
From my understanding of the question,this can use a fairly straight forward solution.Anyway below is the method i propose ,this method takes in a data table and then using SQL statements to insert into a table in the database.Please mind that my solution is using MySQLConnection and MySqlCommand replace it with SqlConnection and SqlCommand.
public void InsertTableIntoDB_CreditLimitSimple(System.Data.DataTable tblFormat)
{
for (int i = 0; i < tblFormat.Rows.Count; i++)
{
String InsertQuery = string.Empty;
InsertQuery = "INSERT INTO customercredit " +
"(ACCOUNT_CODE,NAME,CURRENCY,CREDIT_LIMIT) " +
"VALUES ('" + tblFormat.Rows[i]["AccountCode"].ToString() + "','" + tblFormat.Rows[i]["Name"].ToString() + "','" + tblFormat.Rows[i]["Currency"].ToString() + "','" + tblFormat.Rows[i]["CreditLimit"].ToString() + "')";
using (MySqlConnection destinationConnection = new MySqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ToString()))
using (var dbcm = new MySqlCommand(InsertQuery, destinationConnection))
{
destinationConnection.Open();
dbcm.ExecuteNonQuery();
}
}
}//CreditLimit
Yes, it is called Inline CSS, Here you styling the div
using some height, width, and background.
Here the example:
<div style="width:50px;height:50px;background color:red">
You can achieve same using Internal or External CSS
2.Internal CSS:
<head>
<style>
div {
height:50px;
width:50px;
background-color:red;
foreground-color:white;
}
</style>
</head>
<body>
<div></div>
</body>
3.External CSS:
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div></div>
</body>
style.css /external css file/
div {
height:50px;
width:50px;
background-color:red;
}
You need to define your problem more clearly. You could just take the number of milliseconds between the two Date
objects and divide by the number of milliseconds in 24 hours, for example... but:
Date
is always in UTCYou don't need any plugins to do this.
Just select all lines (Ctrl A) and then from the menu select Edit → Line → Reindent.
This will work if your file is saved with an extension that contains HTML like .html
or .php
.
If you do this often, you may find this key mapping useful:
{ "keys": ["ctrl+shift+r"], "command": "reindent" , "args": { "single_line": false } }
If your file is not saved (e.g. you just pasted in a snippet to a new window), you can manually set the language for indentation by selecting the menu View → Syntax → language of choice
before selecting the reindent option.
ES6 now supports the startsWith()
and endsWith()
method for checking beginning and ending of string
s. If you want to support pre-es6 engines, you might want to consider adding one of the suggested methods to the String
prototype.
if (typeof String.prototype.startsWith != 'function') {
String.prototype.startsWith = function (str) {
return this.match(new RegExp("^" + str));
};
}
if (typeof String.prototype.endsWith != 'function') {
String.prototype.endsWith = function (str) {
return this.match(new RegExp(str + "$"));
};
}
var str = "foobar is not barfoo";
console.log(str.startsWith("foob"); // true
console.log(str.endsWith("rfoo"); // true
There is collection of Func<...>
classes - Func that is probably what you are looking for:
void MyMethod(Func<int> param1 = null)
This defines method that have parameter param1
with default value null
(similar to AS), and a function that returns int
. Unlike AS in C# you need to specify type of the function's arguments.
So if you AS usage was
MyMethod(function(intArg, stringArg) { return true; })
Than in C# it would require param1
to be of type Func<int, siring, bool>
and usage like
MyMethod( (intArg, stringArg) => { return true;} );
Well, you should think about one more thing.
If you have a really big dataset, like 1,000,000 examples, split 80/10/10 may be unnecessary, because 10% = 100,000 examples may be just too much for just saying that model works fine.
Maybe 99/0.5/0.5 is enough because 5,000 examples can represent most of the variance in your data and you can easily tell that model works good based on these 5,000 examples in test and dev.
Don't use 80/20 just because you've heard it's ok. Think about the purpose of the test set.
This works for me:
const from = '2019-01-01';_x000D_
const to = '2019-01-08';_x000D_
_x000D_
Math.abs(_x000D_
moment(from, 'YYYY-MM-DD')_x000D_
.startOf('day')_x000D_
.diff(moment(to, 'YYYY-MM-DD').startOf('day'), 'days')_x000D_
) + 1_x000D_
);
_x000D_
You can use
@PostConstruct
public void init() {
// ...
}
I find Core Graphics to be pretty simple for Swift 3:
if let cgcontext = UIGraphicsGetCurrentContext() {
cgcontext.strokeEllipse(in: CGRect(x: center.x-diameter/2, y: center.y-diameter/2, width: diameter, height: diameter))
}
Using TextEncoder and TextDecoder
var uint8array = new TextEncoder("utf-8").encode("Plain Text");
var string = new TextDecoder().decode(uint8array);
console.log(uint8array ,string )
The following is a regular expression matching a multiline block of text:
import re
result = re.findall('(startText)(.+)((?:\n.+)+)(endText)',input)
You can add the following JS script
<script>
function myfunction(event) {
alert('Checked radio with ID = ' + event.target.id);
}
document.querySelectorAll("input[name='gun']").forEach((input) => {
input.addEventListener('change', myfunction);
});
</script>
for (i = 0, len = Auction.auctions.length; i < len; i++) {
auction = Auction.auctions[i];
Auction.auctions[i]['seconds'] --;
if (auction.seconds < 0) {
Auction.auctions.splice(i, 1);
i--;
len--;
}
}
Since this is still very relevant, the first Google hit and I just spend some time figuring this out, I'll post my (working in Python 3) solution:
testdict = {'one' : '1',
'two' : '2',
'three' : '3',
'four' : '4'
}
value = '2'
[key for key in testdict.items() if key[1] == value][0][0]
Out[1]: 'two'
It will give you the first value that matches.
You should make x
and y
numpy arrays, not lists:
x = np.array([0.46,0.59,0.68,0.99,0.39,0.31,1.09,
0.77,0.72,0.49,0.55,0.62,0.58,0.88,0.78])
y = np.array([0.315,0.383,0.452,0.650,0.279,0.215,0.727,0.512,
0.478,0.335,0.365,0.424,0.390,0.585,0.511])
With this change, it produces the expect plot. If they are lists, m * x
will not produce the result you expect, but an empty list. Note that m
is anumpy.float64
scalar, not a standard Python float
.
I actually consider this a bit dubious behavior of Numpy. In normal Python, multiplying a list with an integer just repeats the list:
In [42]: 2 * [1, 2, 3]
Out[42]: [1, 2, 3, 1, 2, 3]
while multiplying a list with a float gives an error (as I think it should):
In [43]: 1.5 * [1, 2, 3]
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-43-d710bb467cdd> in <module>()
----> 1 1.5 * [1, 2, 3]
TypeError: can't multiply sequence by non-int of type 'float'
The weird thing is that multiplying a Python list with a Numpy scalar apparently works:
In [45]: np.float64(0.5) * [1, 2, 3]
Out[45]: []
In [46]: np.float64(1.5) * [1, 2, 3]
Out[46]: [1, 2, 3]
In [47]: np.float64(2.5) * [1, 2, 3]
Out[47]: [1, 2, 3, 1, 2, 3]
So it seems that the float gets truncated to an int, after which you get the standard Python behavior of repeating the list, which is quite unexpected behavior. The best thing would have been to raise an error (so that you would have spotted the problem yourself instead of having to ask your question on Stackoverflow) or to just show the expected element-wise multiplication (in which your code would have just worked). Interestingly, addition between a list and a Numpy scalar does work:
In [69]: np.float64(0.123) + [1, 2, 3]
Out[69]: array([ 1.123, 2.123, 3.123])
to truncate a decimal I've used the follow code:
<th><%#= sprintf("%0.01f",prom/total) %><!--1dec,aprox-->
<% if prom == 0 or total == 0 %>
N.E.
<% else %>
<%= Integer((prom/total).to_d*10)*0.1 %><!--1decimal,truncado-->
<% end %>
<%#= prom/total %>
</th>
If you want to truncate to 2 decimals, you should use Integr(a*100)*0.01
Place the javascript under a div tag.
<div runat="server"> //div tag must have runat server
//Your Jave script code goes here....
</div>
It'll work!!
You need to make sure the IIS Management Console is installed.
It's a choice (from browser devs or W3C, I can't find any W3C specification about styling select options though) not allowing to style select options.
I suspect this would be to keep consistency with native choice lists.
(think about mobile devices for example).
3 solutions come to my mind:

I like the urllib.urlencode
function, and it doesn't appear to exist in urllib2
.
>>> urllib.urlencode({'abc':'d f', 'def': '-!2'})
'abc=d+f&def=-%212'
I had same issue. No need to re install.

I recommend another option. jQuery UI has a new position feature that allows you to position elements relative to each other. For complete documentation and demo see: http://jqueryui.com/demos/position/#option-offset.
Here's one way to position your elements using the position feature:
var options = {
"my": "top left",
"at": "top left",
"of": ".layer1"
};
$(".layer2").position(options);
This could also be an issue of building the code using a 64 bit
configuration. You can try to select x86
as the build platform which can solve this issue. To do this right-click the solution and select Configuration Manager
From there you can change the Platform
of the project using the 32-bit .dll to x86
#Edit (add explanation :) )
say you have an array you want to update your existing firestore document field with. You can use set(yourData, {merge: true} )
passing setOptions(second param in set function) with {merge: true}
is must in order to merge the changes instead of overwriting. here is what the official documentation says about it
An options object that configures the behavior of set() calls in DocumentReference, WriteBatch, and Transaction. These calls can be configured to perform granular merges instead of overwriting the target documents in their entirety by providing a SetOptions with merge: true.
you can use this
const yourNewArray = [{who: "[email protected]", when:timestamp}
{who: "[email protected]", when:timestamp}]
collectionRef.doc(docId).set(
{
proprietary: "jhon",
sharedWith: firebase.firestore.FieldValue.arrayUnion(...yourNewArray),
},
{ merge: true },
);
hope this helps :)

is the HTTP header sent to the server, specifying a particular format.dataType
is you telling jQuery what kind of response to expect.The $.ajax()
documentation has full descriptions of these as well.
In your particular case, the first is asking for the response to be in UTF-8
, the second doesn't care. Also the first is treating the response as a JavaScript object, the second is going to treat it as a string.
So the first would be:
success: function(data) {
// get data, e.g. data.title;
}
The second:
success: function(data) {
alert("Here's lots of data, just a string: " + data);
}
$ git remote add origin https://github.com/git/git.git
--- You will run this command to link your github project to origin. Here origin is user-defined.
You can rename it by $ git remote rename old-name new-name
$ git fetch origin
- Downloads objects and refs from remote repository to your local computer [origin/master]. That means it will not affect your local master branch unless you merge them using $ git merge origin/master
. Remember to checkout the correct branch where you need to merge before run this command
Note: Fetched content is represented as a remote branch. Fetch gives you a chance to review changes before integrating them into your copy of the project. To show changes between yours and remote $git diff master..origin/master
You mean you want to add a new row and only put data in a certain column? Try the following:
var row = dataTable.NewRow();
row[myColumn].Value = "my new value";
dataTable.Add(row);
As it is a data table, though, there will always be data of some kind in every column. It just might be DBNull.Value
instead of whatever data type you imagine it would be.
based on rogerdpack's and Ed999's responses, I've created my .sh version
#!/bin/bash
[ -e list.txt ] && rm list.txt
for f in *.mp4
do
echo "file $f" >> list.txt
done
ffmpeg -f concat -i list.txt -c copy joined-out.mp4 && rm list.txt
it joins all the *.mp4
files in current folder into joined-out.mp4
tested on mac.
resulting filesize is exact sum of my 60 tested files. Should not be any loss. Just what I needed
You could better use the localStorage of the web browser.
You can find a reference here
You can scroll by using the property contentOffset
in UIScrollView
, e.g.,
CGPoint offset = scrollview.contentOffset;
offset.y -= KEYBOARD_HEIGHT + 5;
scrollview.contentOffset = offset;
There's also a method to do animated scrolling.
As for the reason why your second edit is not scrolling correctly, it could be because you seem to assume that a new keyboard will appear every time editing starts. You could try checking if you've already adjusted for the "keyboard" visible position (and likewise check for keyboard visibility at the moment before reverting it).
A better solution might be to listen for the keyboard notification, e.g.:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardDidShow:)
name:UIKeyboardDidShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification
object:nil];
The SSL certificates are going to be bound to hostname rather than IP if they are setup in the standard way. Hence why it works at one site rather than the other.
Even if the servers share the same hostname they may well have two different certificates and hence WebSphere will have a certificate trust issue as it won't be able to recognise the certificate on the second server as it is different to the first.
Use string formats;
console.log("%s %O", "My Object", obj);
Chrome has Format Specifiers with the following;
%s
Formats the value as a string. %d
or %i
Formats the value as
an integer. %f
Formats the value as a floating point value.%o
Formats the value as an expandable DOM element (as in the
Elements panel). %O
Formats the value as an expandable JavaScript
object. %c
Formats the output string according to CSS styles you
provide.Firefox also has String Substitions which have similar options.
%o
Outputs a hyperlink to a JavaScript object. Clicking the link opens an inspector.%d
or %i
Outputs an integer. Formatting is not yet supported.%s
Outputs a string.%f
Outputs a floating-point value. Formatting is not yet supported.Safari has printf style formatters
%d
or %i
Integer%[0.N]f
Floating-point value with N digits of precision%o
Object%s

When it comes to float
numbers, you can use format specifiers:
f'{value:{width}.{precision}}'
where:
value
is any expression that evaluates to a numberwidth
specifies the number of characters used in total to display, but if value
needs more space than the width specifies then the additional space is used. precision
indicates the number of characters used after the decimal pointWhat you are missing is the type specifier for your decimal value. In this link, you an find the available presentation types for floating point and decimal.
Here you have some examples, using the f
(Fixed point) presentation type:
# notice that it adds spaces to reach the number of characters specified by width
In [1]: f'{1 + 3 * 1.5:10.3f}'
Out[1]: ' 5.500'
# notice that it uses more characters than the ones specified in width
In [2]: f'{3000 + 3 ** (1 / 2):2.1f}'
Out[2]: '3001.7'
In [3]: f'{1.2345 + 4 ** (1 / 2):9.6f}'
Out[3]: ' 3.234500'
# omitting width but providing precision will use the required characters to display the number with the the specified decimal places
In [4]: f'{1.2345 + 3 * 2:.3f}'
Out[4]: '7.234'
# not specifying the format will display the number with as many digits as Python calculates
In [5]: f'{1.2345 + 3 * 0.5}'
Out[5]: '2.7344999999999997'
Example here.
Pasted below:
This is about how to launch android application from the adb shell.
Command: am
Look for invoking path in AndroidManifest.xml
Browser app::
# am start -a android.intent.action.MAIN -n com.android.browser/.BrowserActivity
Starting: Intent { action=android.intent.action.MAIN comp={com.android.browser/com.android.browser.BrowserActivity} }
Warning: Activity not started, its current task has been brought to the front
Settings app::
# am start -a android.intent.action.MAIN -n com.android.settings/.Settings
Starting: Intent { action=android.intent.action.MAIN comp={com.android.settings/com.android.settings.Settings} }
Usually my align environments are set up like
\begin{align}
\label{eqn1}
\lambda_i + \mu_i = 0 \\
\label{eqn2}
\mu_i \xi_i = 0 \\
\label{eqn3}
\lambda_i [y_i( w^T x_i + b) - 1 + \xi_i] = 0
\end{align}
The \label command should be placed in the line you want to reference, the placement in the line does not matter. I prefer to place it at the beginning at the line (as a sort of description) while others place them at the end.
Please note: There is a difference between using String[] to StringBuilder[].
In String - if you change the String, the other arrays we have copied (by CopyTo or Clone) that points to the same string will not change, but the original String array will point to a new String, however, if we use a StringBuilder in an array, the String pointer will not change, therefore, it will affect all the copies we have made for this array. For instance:
public void test()
{
StringBuilder[] sArrOr = new StringBuilder[1];
sArrOr[0] = new StringBuilder();
sArrOr[0].Append("hello");
StringBuilder[] sArrClone = (StringBuilder[])sArrOr.Clone();
StringBuilder[] sArrCopyTo = new StringBuilder[1];
sArrOr.CopyTo(sArrCopyTo,0);
sArrOr[0].Append(" world");
Console.WriteLine(sArrOr[0] + " " + sArrClone[0] + " " + sArrCopyTo[0]);
//Outputs: hello world hello world hello world
//Same result in int[] as using String[]
int[] iArrOr = new int[2];
iArrOr[0] = 0;
iArrOr[1] = 1;
int[] iArrCopyTo = new int[2];
iArrOr.CopyTo(iArrCopyTo,0);
int[] iArrClone = (int[])iArrOr.Clone();
iArrOr[0]++;
Console.WriteLine(iArrOr[0] + " " + iArrClone[0] + " " + iArrCopyTo[0]);
// Output: 1 0 0
}
I solved the same issue 10 minutes ago, so I will give you a short effective fix: Place this inside the application tag or your manifest:
android:theme="@android:style/Theme.Holo"
Also set the Theme of your XML layout to Holo, in the layout's graphical view.
Libraries will be useful if you need to change more complicated theme stuff, but this little fix will work, so you can move on with your app.
I got this error until I realized that I hadn't intialized a Git repository in that folder, on a mounted vagrant machine.
So I typed git init
and then git worked.
For checking existence one can also use (works for both, files and folders):
Not Dir(DirFile, vbDirectory) = vbNullString
The result is True
if a file or a directory exists.
Example:
If Not Dir("C:\Temp\test.xlsx", vbDirectory) = vbNullString Then MsgBox "exists" Else MsgBox "does not exist" End If
No, you can just write the function as:
$(document).ready(function() {
MyBlah("hello");
});
function MyBlah(blah) {
alert(blah);
}
This calls the function MyBlah
on content ready.
Set the DIV's z-index to one larger than the other DIVs. You'll also need to make sure the DIV has a position
other than static
set on it, too.
CSS:
#someDiv {
z-index:9;
}

You can set your activity to use a specific volume. In your activity, use one of the following:
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
this.setVolumeControlStream(AudioManager.STREAM_RING);
this.setVolumeControlStream(AudioManager.STREAM_ALARM);
this.setVolumeControlStream(AudioManager.STREAM_NOTIFICATION);
this.setVolumeControlStream(AudioManager.STREAM_SYSTEM);
this.setVolumeControlStream(AudioManager.STREAM_VOICECALL);
This is my solution using pure Win32/C++ based on the top answer. The idea is to wrap everything required into one function without the need for external callback functions or structures:
#include <utility>
HWND FindTopWindow(DWORD pid)
{
std::pair<HWND, DWORD> params = { 0, pid };
// Enumerate the windows using a lambda to process each window
BOOL bResult = EnumWindows([](HWND hwnd, LPARAM lParam) -> BOOL
{
auto pParams = (std::pair<HWND, DWORD>*)(lParam);
DWORD processId;
if (GetWindowThreadProcessId(hwnd, &processId) && processId == pParams->second)
{
// Stop enumerating
SetLastError(-1);
pParams->first = hwnd;
return FALSE;
}
// Continue enumerating
return TRUE;
}, (LPARAM)¶ms);
if (!bResult && GetLastError() == -1 && params.first)
{
return params.first;
}
return 0;
}
You need to make sure requestAnimFrame stops being called once game == 1. A break statement only exits a traditional loop (e.g. while()
).
function loop() {
if (isPlaying) {
jet1.draw();
drawAllEnemies();
if (game != 1) {
requestAnimFrame(loop);
}
}
}
Or alternatively you could simply skip the second if
condition and change the first condition to if (isPlaying && game !== 1)
. You would have to make a variable called game and give it a value of 0. Add 1 to it every game.
TLDR; Here's why:
The reason this works is because
gulp
tries to run yourgulpfile.js
using your locally installed version ofgulp
, see here. Hence the reason for a global and local install of gulp.
Essentially, when you install gulp
locally the script isn't in your PATH
and so you can't just type gulp
and expect the shell to find the command. By installing it globally the gulp
script gets into your PATH
because the global node/bin/
directory is most likely on your path.
To respect your local dependencies though, gulp
will use your locally installed version of itself to run the gulpfile.js
.
Resized VM with more memory fixed this issue.
Operating system commands have exit codes. Look for Linux exit codes to see some material on this. The shell uses the exit codes to decide if the program worked, had problems, or failed. There are some efforts to create standard (or at least commonly-used) exit codes. See this Advanced Shell Script posting.
There is no mention about nine-patch files here. Yes, you have to create the file, however it's quite easy job and it's really "cross-version and transparency supporting" solution. If the file is placed to the drawable-nodpi
directory, it works px
based, and in the drawable-mdpi
works approximately as dp base (thanks to resample).
Example file for the original question (border-right:1px solid red;) is here:
Just place it to the drawable-nodpi
directory.
You can even try using bool()
like this. Although it is less readable surely it's a concise way to perform this.
a = [1,2,3];
print bool(a); # it will return True
a = [];
print bool(a); # it will return False
I love this way for the checking list is empty or not.
Very handy and useful.
With modern browsers, you can set the textContent
property, see Node.textContent:
var span = document.getElementById("myspan");
span.textContent = "some text";
If you need to get quantity of selected checkboxes:
var selected = []; // initialize array
$('div#checkboxes input[type=checkbox]').each(function() {
if ($(this).is(":checked")) {
selected.push($(this));
}
});
var selectedQuantity = selected.length;
Better yet use a oneliner:
Dump remoteDB to localDB:
mysqldump -uroot -pMypsw -h remoteHost remoteDB | mysql -u root -pMypsw localDB
Dump localDB to remoteDB:
mysqldump -uroot -pmyPsw localDB | mysql -uroot -pMypsw -h remoteHost remoteDB
Use variables i.e. the .BAT
variables and called %0
to %9
One way is using a template function in your directive:
...
template: function(tElem, tAttrs){
return '<div ng-include="' + tAttrs.template + '" />';
}
...
If you're calling native apps, you need to worry about [Environment]::CurrentDirectory
not about PowerShell's $PWD
current directory. For various reasons, PowerShell does not set the process' current working directory when you Set-Location or Push-Location, so you need to make sure you do so if you're running applications (or cmdlets) that expect it to be set.
In a script, you can do this:
$CWD = [Environment]::CurrentDirectory
Push-Location $MyInvocation.MyCommand.Path
[Environment]::CurrentDirectory = $PWD
## Your script code calling a native executable
Pop-Location
# Consider whether you really want to set it back:
# What if another runspace has set it in-between calls?
[Environment]::CurrentDirectory = $CWD
There's no foolproof alternative to this. Many of us put a line in our prompt function to set [Environment]::CurrentDirectory ... but that doesn't help you when you're changing the location within a script.
Two notes about the reason why this is not set by PowerShell automatically:
$PWD
present working directory, but there's only one process, and only one Environment.$PWD
isn't always a legal CurrentDirectory (you might CD into the registry provider for instance).If you want to put it into your prompt (which would only run in the main runspace, single-threaded), you need to use:
[Environment]::CurrentDirectory = Get-Location -PSProvider FileSystem
Try changing it to "subdomain -> subdomain.hosttwo.com"
The CNAME
is an alias for a certain domain, so when you go to the control panel for hostone.com, you shouldn't have to enter the whole name into the CNAME
alias.
As far as the error you are getting, can you log onto subdomain.hostwo.com and check the logs?
I ended up with two changes to the original reply.
document
. This makes it harder to filter only a some of the ajax requests. Soo...This is the code after these changes:
$(document)
.hide() // hide it initially
.ajaxSend(function(event, jqxhr, settings) {
if (settings.url !== "ajax/request.php") return;
$(".spinner").show();
})
.ajaxComplete(function(event, jqxhr, settings) {
if (settings.url !== "ajax/request.php") return;
$(".spinner").hide();
})
For completeness, you can also achieve this in functional components:
const [, updateState] = useState();
const forceUpdate = useCallback(() => updateState({}), []);
// ...
forceUpdate();
Or, as a reusable hook:
const useForceUpdate = () => {
const [, updateState] = useState();
return useCallback(() => updateState({}), []);
}
// const forceUpdate = useForceUpdate();
See: https://stackoverflow.com/a/53215514/2692307
Please note that using a force-update mechanism is still bad practice as it goes against the react mentality, so it should still be avoided if possible.
Given its name, I think the standard way should be delete
:
import numpy as np
A = np.delete(A, 1, 0) # delete second row of A
B = np.delete(B, 2, 0) # delete third row of B
C = np.delete(C, 1, 1) # delete second column of C
According to numpy's documentation page, the parameters for numpy.delete
are as follow:
numpy.delete(arr, obj, axis=None)
arr
refers to the input array, obj
refers to which sub-arrays (e.g. column/row no. or slice of the array) andaxis
refers to either column wise (axis = 1
) or row-wise (axis = 0
) delete operation.Look at my plugin for developing swing application. It is as easy as that of netbeans': http://code.google.com/p/visualswing4eclipse/

If no table with such name exists, DROP
fails with error while DROP IF EXISTS
just does nothing.
This is useful if you create/modifi your database with a script; this way you do not have to ensure manually that previous versions of the table are deleted. You just do a DROP IF EXISTS
and forget about it.
Of course, your current DB engine may not support this option, it is hard to tell more about the error with the information you provide.
byte [] arr = new byte[100]
Each element has 0 by default.
You could find primitive default values here:
Data Type Default Value
byte 0
short 0
int 0
long 0L
float 0.0f
double 0.0d
char '\u0000'
boolean false
1 = 1 expression is commonly used in generated sql code. This expression can simplify sql generating code reducing number of conditional statements.
Well, the problem is that Files.newBufferedReader(Path path)
is implemented like this :
public static BufferedReader newBufferedReader(Path path) throws IOException {
return newBufferedReader(path, StandardCharsets.UTF_8);
}
so basically there is no point in specifying UTF-8
unless you want to be descriptive in your code.
If you want to try a "broader" charset you could try with StandardCharsets.UTF_16
, but you can't be 100% sure to get every possible character anyway.
Character.getNumericValue(c)
The java.lang.Character.getNumericValue(char ch)
returns the int
value that the specified Unicode character represents. For example, the character '\u216C'
(the roman numeral fifty) will return an int with a value of 50.
The letters A-Z in their uppercase ('\u0041' through '\u005A')
, lowercase ('\u0061' through '\u007A')
, and full width variant ('\uFF21' through '\uFF3A' and '\uFF41' through '\uFF5A')
forms have numeric values from 10 through 35. This is independent of the Unicode specification, which does not assign numeric values to these char values.
This method returns the numeric value of the character, as a nonnegative int value;
-2 if the character has a numeric value that is not a nonnegative integer;
-1 if the character has no numeric value.
And here is the link.
jsonIssues = [...jsonIssues,{ID:'3',Name:'name 3',Notes:'NOTES 3'}]
You want your if
check to be:
{% if not loop.last %}

{% endif %}
Note that you can also shorten the code by using If Expression:
{{ ", " if not loop.last else "" }}
I have a simple solution on handling home button press. Here is my code, it can be useful:
public class LifeCycleActivity extends Activity {
boolean activitySwitchFlag = false;
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if(keyCode == KeyEvent.KEYCODE_BACK)
{
activitySwitchFlag = true;
// activity switch stuff..
return true;
}
return false;
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public void onPause(){
super.onPause();
Log.v("TAG", "onPause" );
if(activitySwitchFlag)
Log.v("TAG", "activity switch");
else
Log.v("TAG", "home button");
activitySwitchFlag = false;
}
public void gotoNext(View view){
activitySwitchFlag = true;
startActivity(new Intent(LifeCycleActivity.this, NextActivity.class));
}
}
As a summary, put a boolean in the activity, when activity switch occurs(startactivity event), set the variable and in onpause event check this variable..
Use System.Net.WebClient.DownloadFile
:
string remoteUri = "http://www.contoso.com/library/homepage/images/";
string fileName = "ms-banner.gif", myStringWebResource = null;
// Create a new WebClient instance.
using (WebClient myWebClient = new WebClient())
{
myStringWebResource = remoteUri + fileName;
// Download the Web resource and save it into the current filesystem folder.
myWebClient.DownloadFile(myStringWebResource, fileName);
}
This is working Oracle example but it should work in MySQL too.
You are missing smth - see IN after END Replace 'IN' with '=' sign for a single value.

ELSE '0' END) IN (1, 2)
The WPF equivalent would be the System.Windows.MessageBox
. It has a quite similar interface, but uses other enumerations for parameters and return value.
Like the accepted answer well explained by lhunath, you can use
command > >(tee -a stdout.log) 2> >(tee -a stderr.log >&2)
Beware than if you use bash you could have some issue.
Let me take the matthew-wilcoxson exemple.
And for those who "seeing is believing", a quick test:
(echo "Test Out";>&2 echo "Test Err") > >(tee stdout.log) 2> >(tee stderr.log >&2)
Personally, when I try, I have this result :
user@computer:~$ (echo "Test Out";>&2 echo "Test Err") > >(tee stdout.log) 2> >(tee stderr.log >&2)
user@computer:~$ Test Out
Test Err
Both message does not appear at the same level. Why Test Out
seem to be put like if it is my previous command ?
Prompt is on a blank line, let me think the process is not finished, and when I press Enter
this fix it.
When I check the content of the files, it is ok, redirection works.
Let take another test.
function outerr() {
echo "out" # stdout
echo >&2 "err" # stderr
}
user@computer:~$ outerr
out
err
user@computer:~$ outerr >/dev/null
err
user@computer:~$ outerr 2>/dev/null
out
Trying again the redirection, but with this function.
function test_redirect() {
fout="stdout.log"
ferr="stderr.log"
echo "$ outerr"
(outerr) > >(tee "$fout") 2> >(tee "$ferr" >&2)
echo "# $fout content :"
cat "$fout"
echo "# $ferr content :"
cat "$ferr"
}
Personally, I have this result :
user@computer:~$ test_redirect
$ outerr
# stdout.log content :
out
out
err
# stderr.log content :
err
user@computer:~$
No prompt on a blank line, but I don't see normal output, stdout.log content seem to be wrong, only stderr.log seem to be ok. If I relaunch it, output can be different...
So, why ?
Because, like explained here :
Beware that in bash, this command returns as soon as [first command] finishes, even if the tee commands are still executed (ksh and zsh do wait for the subprocesses)
So, if you use bash, prefer use the better exemple given in this other answer :
{ { outerr | tee "$fout"; } 2>&1 1>&3 | tee "$ferr"; } 3>&1 1>&2
It will fix the previous issues.
Now, the question is, how to retrieve exit status code ?
$?
does not works.
I have no found better solution than switch on pipefail with set -o pipefail
(set +o pipefail
to switch off) and use ${PIPESTATUS[0]}
like this
function outerr() {
echo "out"
echo >&2 "err"
return 11
}
function test_outerr() {
local - # To preserve set option
! [[ -o pipefail ]] && set -o pipefail; # Or use second part directly
local fout="stdout.log"
local ferr="stderr.log"
echo "$ outerr"
{ { outerr | tee "$fout"; } 2>&1 1>&3 | tee "$ferr"; } 3>&1 1>&2
# First save the status or it will be lost
local status="${PIPESTATUS[0]}" # Save first, the second is 0, perhaps tee status code.
echo "==="
echo "# $fout content :"
echo "<==="
cat "$fout"
echo "===>"
echo "# $ferr content :"
echo "<==="
cat "$ferr"
echo "===>"
if (( status > 0 )); then
echo "Fail $status > 0"
return "$status" # or whatever
fi
}
user@computer:~$ test_outerr
$ outerr
err
out
===
# stdout.log content :
<===
out
===>
# stderr.log content :
<===
err
===>
Fail 11 > 0
Put this code where you define recycler view in activity.
rv_list.addOnItemTouchListener(
new RecyclerItemClickListener(activity, new RecyclerItemClickListener.OnItemClickListener() {
@Override
public void onItemClick(View v, int position) {
Toast.makeText(activity, "" + position, Toast.LENGTH_SHORT).show();
}
})
);
Then make separate class and put this code:
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
private OnItemClickListener mListener;
public interface OnItemClickListener {
public void onItemClick(View view, int position);
}
GestureDetector mGestureDetector;
public RecyclerItemClickListener(Context context, OnItemClickListener listener) {
mListener = listener;
mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
@Override
public boolean onSingleTapUp(MotionEvent e) {
return true;
}
});
}
@Override

If you want to detach existing object follow @Slauma's advice. If you want to load objects without tracking changes use:
var data = context.MyEntities.AsNoTracking().Where(...).ToList();
As mentioned in comment this will not completely detach entities. They are still attached and lazy loading works but entities are not tracked. This should be used for example if you want to load entity only to read data and you don't plan to modify them.
I may be too late to reply this but recently I figured out that jinja2 filters have the capability to handle the generation of encrypted passwords. In my main.yml
I'm generating the encrypted password as:
- name: Creating user "{{ uusername }}" with admin access
user:
name: {{ uusername }}
password: {{ upassword | password_hash('sha512') }}
groups: admin append=yes
when: assigned_role == "yes"
- name: Creating users "{{ uusername }}" without admin access
user:
name: {{ uusername }}
password: {{ upassword | password_hash('sha512') }}
when: assigned_role == "no"
- name: Expiring password for user "{{ uusername }}"
shell: chage -d 0 "{{ uusername }}"
"uusername " and "upassword " are passed as --extra-vars
to the playbook and notice I have used jinja2 filter here to encrypt the passed password.
I have added below tutorial related to this to my blog
As other answers have mentioned, the following calls will compute the hash:
MD5Context md5;
MD5Init(&md5);
MD5Update(&md5, data, datalen);
MD5Final(digest, &md5);
The purpose of splitting it up into that many functions is to let you stream large datasets.
For example, if you're hashing a 10GB file and it doesn't fit into ram, here's how you would go about doing it. You would read the file in smaller chunks and call MD5Update
on them.
MD5Context md5;
MD5Init(&md5);
fread(/* Read a block into data. */)
MD5Update(&md5, data, datalen);
fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);
fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);
...
// Now finish to get the final hash value.
MD5Final(digest, &md5);
You can certainly format the date yourself..
var mydate = new Date(form.startDate.value);
var month = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"][mydate.getMonth()];
var str = month + ' ' + mydate.getFullYear();
You can also use an external library, such as DateJS.
Here's a DateJS example:
<script src="http://www.datejs.com/build/date.js" type="text/javascript"></script>
<script>
var mydate = new Date(form.startDate.value);
var str = mydate.toString("MMMM yyyy");
window.alert(str);
</script>

Debugging environment (using Visual Studio)
1a) Stephen Walter's link to set the startup page on MVC using the project properties is only applicable when you are debugging your MVC application.
1b) Right mouse click on the .aspx page in Solution Explorer and select the "Set As Start Page" behaves the same.
Note: in both the above cases, the startup page setting is only recognised by your Visual Studio Development Server. It is not recognised by your deployed server.
Deployed environment
2a) To set the startup page, assuming that you have not change any of the default routings, change the content of /Views/Home/Index.aspx to do a "Server.Transfer" or a "Response.Redirect" to your desired page.
2b) Change your default routing in your global.asax.cs to your desired page.
Are there any other options that the readers are aware of? Which of the above (including your own option) would be your preferred solution (and please share with us why)?
If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.
Something like:
$("#fbss").keypress(function() {
if($(this).val().length > 1) {
// Enable submit button
} else {
// Disable submit button
}
});
To delete a cookie I set it again with an empty value and expiring in 1 second. In details, I always use one of the following flavours (I tend to prefer the second one):
1.
function setCookie(key, value, expireDays, expireHours, expireMinutes, expireSeconds) {
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = key +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie(name, "", null , null , null, 1);
}
Usage:
setCookie("reminder", "buyCoffee", null, null, 20);
deleteCookie("reminder");
2
function setCookie(params) {
var name = params.name,
value = params.value,
expireDays = params.days,
expireHours = params.hours,
expireMinutes = params.minutes,
expireSeconds = params.seconds;
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = name +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie({name: name, value: "", seconds: 1});
}
Usage:
setCookie({name: "reminder", value: "buyCoffee", minutes: 20});
deleteCookie("reminder");
Try this:
par(adj = 0)
plot(1, 1, main = "Title")
or equivalent:
plot(1, 1, main = "Title", adj = 0)
adj = 0
produces left-justified text, 0.5 (the default) centered text and 1 right-justified text. Any value in [0, 1]
is allowed.
However, the issue is that this will also change the position of the label of the x-axis and y-axis.
If you really should use Double instead of double you even can get the int Value of Double by calling:
Double d = new Double(1.23);
int i = d.intValue();
Else its already described by Peter Lawreys answer.
in my case, I got the same exception because the user that I configured in the app did not existed in the DB, creating the user and granting needed permissions solved the problem.
No need to use expensive regex
, if barely needed then try-
Use r'(/)(?=$)'
pattern that is capture last /
and replace with r''
i.e. blank character.
>>>re.sub(r'(/)(?=$)',r'','/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg/')
>>>'/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg'
My situation was a little different. The solution was to strip the .pem from everything outside of the CERTIFICATE and PRIVATE KEY sections and to invert the order which they appeared. After converting from pfx to pem file, the certificate looked like this:
Bag Attributes
localKeyID: ...
issuer=...
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
Bag Attributes
more garbage...
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
After correcting the file, it was just:
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
we can create multiply strings using * in python but not in java you can use for loop in your case:
String sample="123";
for(int i=0;i<3;i++)
{
sample=+"0";
}
As you noticed, these are Makefile {macros or variables}, not compiler options. They implement a set of conventions. (Macros is an old name for them, still used by some. GNU make doc calls them variables.)
The only reason that the names matter is the default make rules, visible via make -p
, which use some of them.
If you write all your own rules, you get to pick all your own macro names.
In a vanilla gnu make, there's no such thing as CCFLAGS. There are CFLAGS
, CPPFLAGS
, and CXXFLAGS
. CFLAGS
for the C compiler, CXXFLAGS
for C++, and CPPFLAGS
for both.
Why is CPPFLAGS
in both? Conventionally, it's the home of preprocessor flags (-D
, -U
) and both c and c++ use them. Now, the assumption that everyone wants the same define environment for c and c++ is perhaps questionable, but traditional.
P.S. As noted by James Moore, some projects use CPPFLAGS for flags to the C++ compiler, not flags to the C preprocessor. The Android NDK, for one huge example.
@AnsgarWiechers - it's not my experience that querying everything and then pruning the result is more efficient when you're doing a targeted search of known accounts. Although, yes, it is also more efficient to select just the properties you need to return.
The below examples are based on a domain in the range of 20,000 account objects.
measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st }
...
Seconds : 16
Milliseconds : 208
measure-command {$userlist | get-aduser -Properties DisplayName,st}
...
Seconds : 3
Milliseconds : 496
In the second example, $userlist contains 368 account names (just strings, not pre-fetched account objects).
Note that if I include the where
clause per your suggestion to prune to the actually desired results, it's even more expensive.
measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st |where {$userlist -Contains $_.samaccountname } }
...
Seconds : 17
Milliseconds : 876
Indexed attributes seem to have similar performance (I tried just returning displayName
).
Even if I return all user account properties in my set, it's more efficient. (Adding a select statement to the below brings it down by a half-second).
measure-command {$userlist | get-aduser -Properties *}
...
Seconds : 12
Milliseconds : 75
I can't find a good document that was written in ye olde days about AD queries to link to, but you're hitting every account in your search scope to return the properties. This discusses the basics of doing effective AD queries - scoping and filtering: https://msdn.microsoft.com/en-us/library/ms808539.aspx#efficientadapps_topic01
When your search scope is "*", you're still building a (big) list of the objects and iterating through each one. An LDAP search filter is always more efficient to build the list first (or a narrow search base, which is again building a smaller list to query).
it defaults to submitting a form, easiest way is to add "return false"
<button type="cancel" onclick="window.location='http://stackoverflow.com';return false;">Cancel</button>
<div className="display__lbl_input">
<input
type="checkbox"
onChange={this.handleChangeFilGasoil}
value="Filter Gasoil"
name="Filter Gasoil"
id=""
/>
<label htmlFor="">Filter Gasoil</label>
</div>
handleChangeFilGasoil = (e) => {
if(e.target.checked){
this.setState({
checkedBoxFG:e.target.value
})
console.log(this.state.checkedBoxFG)
}
else{
this.setState({
checkedBoxFG : ''
})
console.log(this.state.checkedBoxFG)
}
};
Your second for loop should have j++ instead of i++
It's available in the HTML5 History API. The event is called 'popstate'
In the Developer Tools in Chrome, there is a bar along the top, called the Execution Context Selector
(h/t felipe-sabino), just under the Elements, Network, Sources... tabs, that changes depending on the context of the current tab. When in the Console tab there is a dropdown in that bar that allows you to select the frame context in which the Console will operate. Select your frame in this drop down and you will find yourself in the appropriate frame context. :D

An object file is the real output from the compilation phase. It's mostly machine code, but has info that allows a linker to see what symbols are in it as well as symbols it requires in order to work. (For reference, "symbols" are basically names of global objects, functions, etc.)
A linker takes all these object files and combines them to form one executable (assuming that it can, ie: that there aren't any duplicate or undefined symbols). A lot of compilers will do this for you (read: they run the linker on their own) if you don't tell them to "just compile" using command-line options. (-c
is a common "just compile; don't link" option.)
My version. Hope it helps.

A CharSequence
is an interface, not an actual class. An interface is just a set of rules (methods) that a class must contain if it implements the interface. In Android a CharSequence
is an umbrella for various types of text strings. Here are some of the common ones:
String
(immutable text with no styling spans)StringBuilder
(mutable text with no styling spans)SpannableString
(immutable text with styling spans)SpannableStringBuilder
(mutable text with styling spans)(You can read more about the differences between these here.)
If you have a CharSequence
object, then it is actually an object of one of the classes that implement CharSequence
. For example:
CharSequence myString = "hello";
CharSequence mySpannableStringBuilder = new SpannableStringBuilder();
The benefit of having a general umbrella type like CharSequence
is that you can handle multiple types with a single method. For example, if I have a method that takes a CharSequence
as a parameter, I could pass in a String
or a SpannableStringBuilder
and it would handle either one.
public int getLength(CharSequence text) {
return text.length();
}
You could say that a String
is just one kind of CharSequence
. However, unlike CharSequence
, it is an actual class, so you can make objects from it. So you could do this:
String myString = new String();
but you can't do this:
CharSequence myCharSequence = new CharSequence(); // error: 'CharSequence is abstract; cannot be instantiated
Since CharSequence
is just a list of rules that String
conforms to, you could do this:
CharSequence myString = new String();
That means that any time a method asks for a CharSequence
, it is fine to give it a String
.
String myString = "hello";
getLength(myString); // OK
// ...
public int getLength(CharSequence text) {
return text.length();
}
However, the opposite is not true. If the method takes a String
parameter, you can't pass it something that is only generally known to be a CharSequence
, because it might actually be a SpannableString
or some other kind of CharSequence
.
CharSequence myString = "hello";
getLength(myString); // error
// ...
public int getLength(String text) {
return text.length();
}

In Drupal
I have a Drupal 6 site. I was on the admin "modules" page, and noticed the tables had this exact feature!
Looking at the code, it seems to be implemented by a file called tableheader.js
. It applies the feature on all tables with the class sticky-enabled
.
For a Drupal site, I'd like to be able to make use of that tableheader.js
module as-is for user content. tableheader.js
doesn't seem to be present on user content pages in Drupal. I posted a forum message to ask how to modify the Drupal theme so it's available. According to a response, tableheader.js
can be added to a Drupal theme using drupal_add_js()
in the theme's template.php
as follows:
drupal_add_js('misc/tableheader.js', 'core');
It is a not-often-acknowledged fact that the block size of a block cipher is also an important security consideration (though nowhere near as important as the key size).
Blowfish (and most other block ciphers of the same era, like 3DES and IDEA) have a 64 bit block size, which is considered insufficient for the large file sizes which are common these days (the larger the file, and the smaller the block size, the higher the probability of a repeated block in the ciphertext - and such repeated blocks are extremely useful in cryptanalysis).
AES, on the other hand, has a 128 bit block size. This consideration alone is justification to use AES instead of Blowfish.
Twitter bootstrap tables can be styled and well designed. You can style your table just adding some classes on your table and it’ll look nice. You might use it on your data reports, showing information, etc.
You can use :
basic table
Striped rows
Bordered table
Hover rows
Condensed table
Contextual classes
Responsive tables
Striped rows Table :
<table class="table table-striped" width="647">
<thead>
<tr>
<th>#</th>
<th>Name</th>
<th>Address</th>
<th>mail</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Thomas bell</td>
<td>Brick lane, London</td>
<td>[email protected]</td>
</tr>
<tr>
<td height="29">2</td>
<td>Yan Chapel</td>
<td>Toronto Australia</td>
<td>[email protected]</td>
</tr>
<tr>
<td>3</td>
<td>Pit Sampras</td>
<td>Berlin, Germany</td>
<td>Pit @yahoo.com</td>
</tr>
</tbody>
</table>
Condensed table :
Compacting a table you need to add class class=”table table-condensed” .
<table class="table table-condensed" width="647">
<thead>
<tr>
<th>#</th>
<th>Sample Name</th>
<th>Address</th>
<th>Mail</th>
</tr>
</thead>

This seems to work fine for me on all browsers. Example is an actual ad i use online and in newsletter. Just change the content of the div. It will adjust and shrinkwrap with the amount of padding you specify.
<div style="float:left; border: 3px ridge red; background: aqua; padding:12px">
<font color=red size=4>Need to fix a birth certificate? Learn <a href="http://www.example.com">Photoshop in a Day</a>!
</font>
</div>
<%@ page import = "java.util.Map" %>
Map<String, String[]> parameters = request.getParameterMap();
for(String parameter : parameters.keySet()) {
if(parameter.toLowerCase().startsWith("question")) {
String[] values = parameters.get(parameter);
//your code here
}
}
There are several ways to do this depending on the file format required.
I would use the standard configparser approach unless there were compelling reasons to use a different format.
Write a file like so:
# python 2.x
# from ConfigParser import SafeConfigParser
# config = SafeConfigParser()
# python 3.x
from configparser import ConfigParser
config = ConfigParser()
config.read('config.ini')
config.add_section('main')
config.set('main', 'key1', 'value1')
config.set('main', 'key2', 'value2')
config.set('main', 'key3', 'value3')
with open('config.ini', 'w') as f:
config.write(f)
The file format is very simple with sections marked out in square brackets:
[main]
key1 = value1
key2 = value2
key3 = value3
Values can be extracted from the file like so:
# python 2.x
# from ConfigParser import SafeConfigParser
# config = SafeConfigParser()
# python 3.x
from configparser import ConfigParser
config = ConfigParser()
config.read('config.ini')
print config.get('main', 'key1') # -> "value1"
print config.get('main', 'key2') # -> "value2"
print config.get('main', 'key3') # -> "value3"
# getfloat() raises an exception if the value is not a float
a_float = config.getfloat('main', 'a_float')
# getint() and getboolean() also do this for their respective types
an_int = config.getint('main', 'an_int')
JSON data can be very complex and has the advantage of being highly portable.
Write data to a file:
import json
config = {"key1": "value1", "key2": "value2"}
with open('config1.json', 'w') as f:
json.dump(config, f)
Read data from a file:
import json
with open('config.json', 'r') as f:
config = json.load(f)
#edit the data
config['key3'] = 'value3'
#write it back to the file
with open('config.json', 'w') as f:
json.dump(config, f)
A basic YAML example is provided in this answer. More details can be found on the pyYAML website.
Yet another solution would be to use the isin
method. Use it to determine whether each value is infinite or missing and then chain the all
method to determine if all the values in the rows are infinite or missing.
Finally, use the negation of that result to select the rows that don't have all infinite or missing values via boolean indexing.
all_inf_or_nan = df.isin([np.inf, -np.inf, np.nan]).all(axis='columns')
df[~all_inf_or_nan]
An alternative would be simple js date() function, if you don't want to use jQuery/jQuery plugin:
e.g.:
var formattedDate = new Date("yourUnformattedOriginalDate");
var d = formattedDate.getDate();
var m = formattedDate.getMonth();
m += 1; // JavaScript months are 0-11
var y = formattedDate.getFullYear();
$("#txtDate").val(d + "." + m + "." + y);
see: 10 ways to format time and date using JavaScript
If you want to add leading zeros to day/month, this is a perfect example: Javascript add leading zeroes to date
and if you want to add time with leading zeros try this: getMinutes() 0-9 - how to with two numbers?
Just wanted to add a second answer. If you have already rendered the select as a select2, you will need to have that reflected in your selector as follows:
$("#s2id_originalSelectId").select2("val", "value to select");
For Java 8 and above, it's easy:
when(mock.process(Matchers.anyList()));
For Java 7 and below, the compiler needs a bit of help. Use anyListOf(Class<T> clazz)
:
when(mock.process(Matchers.anyListOf(Bar.class)));
Like mentioned earlier, I'd recommend boost lexical_cast. Not only does it have a fairly nice syntax:
#include <boost/lexical_cast.hpp>
std::string s = boost::lexical_cast<std::string>(i);
it also provides some safety:
try{
std::string s = boost::lexical_cast<std::string>(i);
}catch(boost::bad_lexical_cast &){
...
}
I'm a bit late to the answer, but you may want to do this if you want the whole element, not only the values you want to group by:
var query = doc.Elements("whatever")
.GroupBy(element => new {
id = (int) element.Attribute("id"),
category = (int) element.Attribute("cat") })
.Select(e => e.First());
This will give you the first whole element matching your group by selection, much like Jon Skeets second example using DistinctBy, but without implementing IEqualityComparer comparer. DistinctBy will most likely be faster, but the solution above will involve less code if performance is not an issue.

You actually don't need any jQuery to check if there is an overflow happening or not. Using element.offsetHeight
, element.offsetWidth
, element.scrollHeight
and element.scrollWidth
you can determine if your element have content bigger than it's size:
if (element.offsetHeight < element.scrollHeight ||
element.offsetWidth < element.scrollWidth) {
// your element have overflow
} else {
// your element doesn't have overflow
}
See example in action: Fiddle
But if you want to know what element inside your element is visible or not then you need to do more calculation. There is three states for a child element in terms of visibility:
If you want to count semi-visible items it would be the script you need:
var invisibleItems = [];
for(var i=0; i<element.childElementCount; i++){
if (element.children[i].offsetTop + element.children[i].offsetHeight >
element.offsetTop + element.offsetHeight ||
element.children[i].offsetLeft + element.children[i].offsetWidth >
element.offsetLeft + element.offsetWidth ){
invisibleItems.push(element.children[i]);
}
}
And if you don't want to count semi-visible you can calculate with a little difference.
Can someone help me with the exact syntax?
It's a three-step process, and it involves modifying the openssl.cnf
file. You might be able to do it with only command line options, but I don't do it that way.
Find your openssl.cnf
file. It is likely located in /usr/lib/ssl/openssl.cnf
:
$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf
On my Debian system, /usr/lib/ssl/openssl.cnf
is used by the built-in openssl
program. On recent Debian systems it is located at /etc/ssl/openssl.cnf
You can determine which openssl.cnf
is being used by adding a spurious XXX
to the file and see if openssl
chokes.
First, modify the req
parameters. Add an alternate_names
section to openssl.cnf
with the names you want to use. There are no existing alternate_names
sections, so it does not matter where you add it.
[ alternate_names ]
DNS.1 = example.com
DNS.2 = www.example.com
DNS.3 = mail.example.com
DNS.4 = ftp.example.com
Next, add the following to the existing [ v3_ca ]
section. Search for the exact string [ v3_ca ]
:
subjectAltName = @alternate_names
You might change keyUsage
to the following under [ v3_ca ]
:
keyUsage = digitalSignature, keyEncipherment
digitalSignature
and keyEncipherment
are standard fare for a server certificate. Don't worry about nonRepudiation
. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.
In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.
Second, modify the signing parameters. Find this line under the CA_default
section:
# Extension copying option: use with caution.
# copy_extensions = copy
And change it to:

I am very late to this question, however I did encounter this problem and, after much searching, I found this information from Bryan Kennedy: http://plusbryan.com/mysql-replication-without-downtime
On Master take a backup like this:
mysqldump --skip-lock-tables --single-transaction --flush-logs --hex-blob --master-data=2 -A > ~/dump.sql
Now, examine the head of the file and jot down the values for MASTER_LOG_FILE and MASTER_LOG_POS. You will need them later: head dump.sql -n80 | grep "MASTER_LOG"
Copy the "dump.sql" file over to Slave and restore it: mysql -u mysql-user -p < ~/dump.sql
Connect to Slave mysql and run a command like this: CHANGE MASTER TO MASTER_HOST='master-server-ip', MASTER_USER='replication-user', MASTER_PASSWORD='slave-server-password', MASTER_LOG_FILE='value from above', MASTER_LOG_POS=value from above; START SLAVE;
To check the progress of Slave: SHOW SLAVE STATUS;
If all is well, Last_Error will be blank, and Slave_IO_State will report “Waiting for master to send event”. Look for Seconds_Behind_Master which indicates how far behind it is. YMMV. :)
Maximum element value in priceValues[] is maxPriceValues :
double[] priceValues = new double[3];
priceValues [0] = 1;
priceValues [1] = 2;
priceValues [2] = 3;
double maxPriceValues = priceValues.Max();
Open your Android SDK Manager and ensure that you download/install a system image for the API level you are developing with.
You have to start a service in your Application class to run it always. If you do that, your service will be always running. Even though user terminates your app from task manager or force stop your app, it will start running again.
Create a service:
public class YourService extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// do your jobs here
return super.onStartCommand(intent, flags, startId);
}
}
Create an Application class and start your service:
public class App extends Application {
@Override
public void onCreate() {
super.onCreate();
startService(new Intent(this, YourService.class));
}
}
Add "name" attribute into the "application" tag of your AndroidManifest.xml
android:name=".App"
Also, don't forget to add your service in the "application" tag of your AndroidManifest.xml
<service android:name=".YourService"/>
And also this permission request in the "manifest" tag (if API level 28 or higher):
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
UPDATE
After Android Oreo, Google introduced some background limitations. Therefore, this solution above won't work probably. When a user kills your app from task manager, Android System will kill your service as well. If you want to run a service which is always alive in the background. You have to run a foreground service with showing an ongoing notification. So, edit your service like below.
public class YourService extends Service {
private static final int NOTIF_ID = 1;
private static final String NOTIF_CHANNEL_ID = "Channel_Id";
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId){
// do your jobs here
startForeground();
return super.onStartCommand(intent, flags, startId);
}
private void startForeground() {
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);
startForeground(NOTIF_ID, new NotificationCompat.Builder(this,
NOTIF_CHANNEL_ID) // don't forget create a notification channel first
.setOngoing(true)
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle(getString(R.string.app_name))
.setContentText("Service is running background")
.setContentIntent(pendingIntent)
.build());
}
}
EDIT: RESTRICTED OEMS
Unfortunately, some OEMs (Xiaomi, OnePlus, Samsung, Huawei etc.) restrict background operations due to provide longer battery life. There is no proper solution for these OEMs. Users need to allow some special permissions that are specific for OEMs or they need to add your app into whitelisted app list by device settings. You can find more detail information from https://dontkillmyapp.com/.
If background operations are an obligation for you, you need to explain it to your users why your feature is not working and how they can enable your feature by allowing those permissions. I suggest you to use AutoStarter library (https://github.com/judemanutd/AutoStarter) in order to redirect your users regarding permissions page easily from your app.
By the way, if you need to run some periodic work instead of having continuous background job. You better take a look WorkManager (https://developer.android.com/topic/libraries/architecture/workmanager)
I think it will be easy to you. I am using group_concat which concatenate diffent values with separator as we have defined
select ID,User, GROUP_CONCAT(Distinct Department order by Department asc
separator ', ') as Department from Table_Name group by ID
These answers are overly complicated. You can change the main body font size (as well as any other CSS you might want to change) simply by embedding CSS directly into the Rmarkdown document using the html <style>
tag. You do not need an entire CSS file for something so simple. If you are doing a lot of CSS then use a separate CSS file. If you are just modifying a couple of simple things I would do it like this.
---
title: "Untitled"
author: "James"
date: "9/29/2020"
output: html_document
---
<style type="text/css">
body{
font-size: 12pt;
}
</style>
```{r setup, include = FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
Try to set response dataType property directly:
dataType: 'text'
and put
die('');
in the end of your php file. You've got error callback cause jquery cannot parse your response. In anyway, you may use a "complete:" callback, just to make sure your request has been processed.
It is clear that most people who haven't used SQL Server Enterprise Manager don't understand the question (i.e. Justin Cave).
I came upon this post when I wanted to know the same thing.
Using SQL Server, when you are editing your data through the MS SQL Server GUI Tools, you can use a KEYBOARD SHORTCUT to insert a NULL rather than having just an EMPTY CELL, as they aren't the same thing. An empty cell can have a space in it, rather than being NULL, even if it is technically empty. The difference is when you intentionally WANT to put a NULL in a cell rather than a SPACE or to empty it and NOT using a SQL statement to do so.
So, the question really is, how do I put a NULL value in the cell INSTEAD of a space to empty the cell?
I think the answer is, that the way the Oracle Developer GUI works, is as Laniel indicated above, And THAT should be marked as the answer to this question.
Oracle Developer seems to default to NULL when you empty a cell the way the op is describing it.
Additionally, you can force Oracle Developer to change how your null cells look by changing the color of the background color to further demonstrate when a cell holds a null:
Tools->Preferences->Advanced->Display Null Using Background Color
or even the VALUE it shows when it's null:
Tools->Preferences->Advanced->Display Null Value As
Hope that helps in your transition.
Since Java 1.5 we can use the method java.lang.String.format(String, Object...) and use printf like format.
The format string "%1$15s"
do the job. Where 1$
indicates the argument index, s
indicates that the argument is a String and 15
represents the minimal width of the String.
Putting it all together: "%1$15s"
.
For a general method we have:
public static String fixedLengthString(String string, int length) {
return String.format("%1$"+length+ "s", string);
}
Maybe someone can suggest another format string to fill the empty spaces with an specific character?
Improving on Gordon Wilson solution, here is my try:
def to_time
#Convert a fraction of a day to a number of microseconds
usec = (sec_fraction * 60 * 60 * 24 * (10**6)).to_i
t = Time.gm(year, month, day, hour, min, sec, usec)
t - offset.abs.div(SECONDS_IN_DAY)
end
You'll get the same time in UTC, loosing the timezone (unfortunately)
Also, if you have ruby 1.9, just try the to_time
method
The following can be used to retreive an environment parameter:
println System.getenv("MY_PARAM")
Okay so three big things I noticed
You need to include the header file in your class file
Never, EVER place a using directive inside of a header or class, rather do something like std::cout << "say stuff";
Structs are completely defined within a header, structs are essentially classes that default to public
Hope this helps!

I was messing/musing on one-liners involving querySelector() & ended up here, & have a possible answer to the OP question using tag names & querySelector(), with credits to @JaredMcAteer for answering MY question, aka have RegEx-like matches with querySelector() in vanilla Javascript
Hoping the following will be useful & fit the OP's needs or everyone else's:
// basically, of before:
var youtubeDiv = document.querySelector('iframe[src="http://www.youtube.com/embed/Jk5lTqQzoKA"]')
// after
var youtubeDiv = document.querySelector('iframe[src^="http://www.youtube.com"]');
// or even, for my needs
var youtubeDiv = document.querySelector('iframe[src*="youtube"]');
Then, we can, for example, get the src stuff, etc ...
console.log(youtubeDiv.src);
//> "http://www.youtube.com/embed/Jk5lTqQzoKA"
console.debug(youtubeDiv);

PHP's var_export() usually shows a serialized version of the object that can be exec()'d to re-create the object. The closest thing to that in Python is repr()
"For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval() [...]"
The Junction command line utility from SysInternals makes creating and deleting junctions easy.
If you want to combine both paths without losing any path you can use this:
?Path.Combine(@"C:\test", @"\test".Substring(0, 1) == @"\" ? @"\test".Substring(1, @"\test".Length - 1) : @"\test");
Or with variables:
string Path1 = @"C:\Test";
string Path2 = @"\test";
string FullPath = Path.Combine(Path1, Path2.IsRooted() ? Path2.Substring(1, Path2.Length - 1) : Path2);
Both cases return "C:\test\test".
First, I evaluate if Path2 starts with / and if it is true, return Path2 without the first character. Otherwise, return the full Path2.
As many other answers have already pointed out, this can be achieved by adding maximum-scale
to the meta viewport
tag. However, this has the negative consequence of disabling user zoom on Android devices. (It does not disable user zoom on iOS devices since v10.)
We can use JavaScript to dynamically add maximum-scale
to the meta viewport
when the device is iOS. This achieves the best of both worlds: we allow the user to zoom and prevent iOS from zooming into text fields on focus.
| maximum-scale | iOS: can zoom | iOS: no text field zoom | Android: can zoom |
| ------------------------- | ------------- | ----------------------- | ----------------- |
| yes | yes | yes | no |
| no | yes | no | yes |
| yes on iOS, no on Android | yes | yes | yes |
Code:
const addMaximumScaleToMetaViewport = () => {
const el = document.querySelector('meta[name=viewport]');
if (el !== null) {
let content = el.getAttribute('content');
let re = /maximum\-scale=[0-9\.]+/g;
if (re.test(content)) {
content = content.replace(re, 'maximum-scale=1.0');
} else {
content = [content, 'maximum-scale=1.0'].join(', ')
}
el.setAttribute('content', content);
}
};
const disableIosTextFieldZoom = addMaximumScaleToMetaViewport;
// https://stackoverflow.com/questions/9038625/detect-if-device-is-ios/9039885#9039885
const checkIsIOS = () =>
/iPad|iPhone|iPod/.test(navigator.userAgent) && !window.MSStream;
if (checkIsIOS()) {
disableIosTextFieldZoom();
}

You'll do it the same way you would apply a css selector. For instanse you can do
$("#mydiv > .myclass")
or
$("#mydiv .myclass")
The last one will match every myclass inside myDiv, including myclass inside myclass.
Building on @rprog's answer, you can combine the various pieces of the suffix & filter step into one line using a negative regex:
dfNew = df.merge(df2, left_index=True, right_index=True,
how='outer', suffixes=('', '_DROP')).filter(regex='^(?!.*_DROP)')
Or using df.join
:
dfNew = df.join(df2, lsuffix="DROP").filter(regex="^(?!.*DROP)")
The regex here is keeping anything that does not end with the word "DROP", so just make sure to use a suffix that doesn't appear among the columns already.
Renaming a column in MySQL :
ALTER TABLE mytable CHANGE current_column_name new_column_name DATATYPE;
It does not work because your script in JSFiddle is running inside it's own scope (see the "OnLoad" drop down on the left?).
One way around this is to bind your event handler in javascript (where it should be):
document.getElementById('optionID').onchange = function () {
document.getElementById("message").innerHTML = "Having a Baby!!";
};
Another way is to modify your code for the fiddle environment and explicitly declare your function as global so it can be found by your inline event handler:
window.changeMessage() {
document.getElementById("message").innerHTML = "Having a Baby!!";
};

I usually just type:
gcm notepad
or
gcm note*
gcm is the default alias for Get-Command.
On my system, gcm note* outputs:

Application notepad.exe C:\WINDOWS\notepad.exe
Application notepad.exe C:\WINDOWS\system32\notepad.exe

You get the directory and the command that matches what you're looking for.
For people trying to grab the component instance inside a *ngIf
or *ngSwitchCase
, you can follow this trick.
Create an init
directive.
import {
Directive,
EventEmitter,
Output,
OnInit,
ElementRef
} from '@angular/core';
@Directive({
selector: '[init]'
})
export class InitDirective implements OnInit {
constructor(private ref: ElementRef) {}
@Output() init: EventEmitter<ElementRef> = new EventEmitter<ElementRef>();
ngOnInit() {
this.init.emit(this.ref);
}
}
Export your component with a name such as myComponent
@Component({
selector: 'wm-my-component',
templateUrl: 'my-component.component.html',
styleUrls: ['my-component.component.css'],
exportAs: 'myComponent'
})
export class MyComponent { ... }
Use this template to get the ElementRef
AND MyComponent
instance
<div [ngSwitch]="type">
<wm-my-component
#myComponent="myComponent"
*ngSwitchCase="Type.MyType"
(init)="init($event, myComponent)">
</wm-my-component>
</div>
Use this code in TypeScript
init(myComponentRef: ElementRef, myComponent: MyComponent) {
}
In order to set the value of integer variable we simply assign the value to it.
eg g1val = 0
where as set keyword is used to assign value to object.
Sub test()
Dim g1val, g2val As Integer
g1val = 0
g2val = 0
For i = 3 To 18
If g1val > Cells(33, i).Value Then
g1val = g1val
Else
g1val = Cells(33, i).Value
End If
Next i
For j = 32 To 57
If g2val > Cells(31, j).Value Then
g2val = g2val
Else
g2val = Cells(31, j).Value
End If
Next j
End Sub

without disabling the selected value on submitting..
$('#selectID option:not(:selected)').prop('disabled', true);
If you use Jquery version lesser than 1.7
$('#selectID option:not(:selected)').attr('disabled', true);
It works for me..
Actually, passing a bitmap as a Parcelable will result in a "JAVA BINDER FAILURE" error. Try passing the bitmap as a byte array and building it for display in the next activity.
I shared my solution here:
how do you pass images (bitmaps) between android activities using bundles?
You can also try this, if this is what you need:
<style type="text/css">
....
table td div {height:20px;overflow-y:hidden;}
table td.col1 div {width:100px;}
table td.col2 div {width:300px;}
</style>
<table>
<tbody>
<tr><td class="col1"><div>test</div></td></tr>
<tr><td class="col2"><div>test</div></td></tr>
</tbody>
</table>

I hear the argument all the time that whether or not a table is pluralized is all a matter of personal taste and there is no best practice. I don't believe that is true, especially as a programmer as opposed to a DBA. As far as I am aware, there are no legitimate reasons to pluralize a table name other than "It just makes sense to me because it's a collection of objects," while there are legitimate gains in code by having singular table names. For example:
It avoids bugs and mistakes caused by plural ambiguities. Programmers aren't exactly known for their spelling expertise, and pluralizing some words are confusing. For example, does the plural word end in 'es' or just 's'? Is it persons or people? When you work on a project with large teams, this can become an issue. For example, an instance where a team member uses the incorrect method to pluralize a table he creates. By the time I interact with this table, it is used all over in code I don't have access to or would take too long to fix. The result is I have to remember to spell the table wrong every time I use it. Something very similar to this happened to me. The easier you can make it for every member of the team to consistently and easily use the exact, correct table names without errors or having to look up table names all the time, the better. The singular version is much easier to handle in a team environment.
If you use the singular version of a table name AND prefix the primary key with the table name, you now have the advantage of easily determining a table name from a primary key or vice versa via code alone. You can be given a variable with a table name in it, concatenate "Id" to the end, and you now have the primary key of the table via code, without having to do an additional query. Or you can cut off "Id" from the end of a primary key to determine a table name via code. If you use "id" without a table name for the primary key, then you cannot via code determine the table name from the primary key. In addition, most people who pluralize table names and prefix PK columns with the table name use the singular version of the table name in the PK (for example statuses and status_id), making it impossible to do this at all.
If you make table names singular, you can have them match the class names they represent. Once again, this can simplify code and allow you to do really neat things, like instantiating a class by having nothing but the table name. It also just makes your code more consistent, which leads to...
If you make the table name singular, it makes your naming scheme consistent, organized, and easy to maintain in every location. You know that in every instance in your code, whether it's in a column name, as a class name, or as the table name, it's the same exact name. This allows you to do global searches to see everywhere that data is used. When you pluralize a table name, there will be cases where you will use the singular version of that table name (the class it turns into, in the primary key). It just makes sense to not have some instances where your data is referred to as plural and some instances singular.
To sum it up, if you pluralize your table names you are losing all sorts of advantages in making your code smarter and easier to handle. There may even be cases where you have to have lookup tables/arrays to convert your table names to object or local code names you could have avoided. Singular table names, though perhaps feeling a little weird at first, offer significant advantages over pluralized names and I believe are best practice.
The standard approach is to give the centered element fixed dimensions, and place it absolutely:
<div class='fullscreenDiv'>
<div class="center">Hello World</div>
</div>?
.center {
position: absolute;
width: 100px;
height: 50px;
top: 50%;
left: 50%;
margin-left: -50px; /* margin is -0.5 * dimension */
margin-top: -25px;
}?
It works in samsung touchwiz launcher
public static void setBadge(Context context, int count) {
String launcherClassName = getLauncherClassName(context);
if (launcherClassName == null) {
return;
}
Intent intent = new Intent("android.intent.action.BADGE_COUNT_UPDATE");
intent.putExtra("badge_count", count);
intent.putExtra("badge_count_package_name", context.getPackageName());
intent.putExtra("badge_count_class_name", launcherClassName);
context.sendBroadcast(intent);
}
public static String getLauncherClassName(Context context) {
PackageManager pm = context.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, 0);
for (ResolveInfo resolveInfo : resolveInfos) {
String pkgName = resolveInfo.activityInfo.applicationInfo.packageName;
if (pkgName.equalsIgnoreCase(context.getPackageName())) {
String className = resolveInfo.activityInfo.name;
return className;
}
}
return null;
}
In my current project the solution looks like this:
I created an abstract Language State
$stateProvider.state('language', {
abstract: true,
url: '/:language',
template: '<div ui-view class="lang-{{language}}"></div>'
});
Every state in the project has to depend on this state
$stateProvider.state('language.dashboard', {
url: '/dashboard'
//....
});
The language switch buttons calls a custom function:
<a ng-click="footer.setLanguage('de')">de</a>
And the corresponding function looks like this (inside a controller of course):
this.setLanguage = function(lang) {
FooterLog.log('switch to language', lang);
$state.go($state.current, { language: lang }, {
location: true,
reload: true,
inherit: true
}).then(function() {
FooterLog.log('transition successfull');
});
};
This works, but there is a nicer solution just changing a value in the state params from html:
<a ui-sref="{ language: 'de' }">de</a>
Unfortunately this does not work, see https://github.com/angular-ui/ui-router/issues/1031

Is it possible to select an element if it contains a specific child element?
Unfortunately not yet.
The CSS2 and CSS3 selector specifications do not allow for any sort of parent selection.
This is a disclaimer about the accuracy of this post from this point onward. Parent selectors in CSS have been discussed for many years. As no consensus has been found, changes keep happening. I will attempt to keep this answer up-to-date, however be aware that there may be inaccuracies due to changes in the specifications.
An older "Selectors Level 4 Working Draft" described a feature which was the ability to specify the "subject" of a selector. This feature has been dropped and will not be available for CSS implementations.
The subject was going to be the element in the selector chain that would have styles applied to it.
Example HTML<p><span>lorem</span> ipsum dolor sit amet</p>
<p>consecteture edipsing elit</p>
This selector would style the span
element
p span {
color: red;
}
This selector would style the p
element
!p span {
color: red;
}
A more recent "Selectors Level 4 Editor’s Draft" includes "The Relational Pseudo-class: :has()
"
:has()
would allow an author to select an element based on its contents. My understanding is it was chosen to provide compatibility with jQuery's custom :has()
pseudo-selector*.
In any event, continuing the example from above, to select the p
element that contains a span
one could use:
p:has(span) {
color: red;
}
* This makes me wonder if jQuery had implemented selector subjects whether subjects would have remained in the specification.
You can use the SimpleXMLElement::asXML()
method to accomplish this:
$string = "<element><child>Hello World</child></element>";
$xml = new SimpleXMLElement($string);
// The entire XML tree as a string:
// "<element><child>Hello World</child></element>"
$xml->asXML();
// Just the child node as a string:
// "<child>Hello World</child>"
$xml->child->asXML();
To check what is your root directory go to httpd.conf file of apache and search for "DocumentRoot".The location following it is your root directory
Yes, the problem is that there are no commits in "bare". This is a problem with the first commit only, if you create the repos in the order (bare,alice). Try doing:
git push --set-upstream origin master
This would only be required the first time. Afterwards it should work normally.
As Chris Johnsen pointed out, you would not have this problem if your push.default was customized. I like upstream/tracking.
This issue is also present on iOS Chrome.
I glanced through all the solutions above, most are very hacky.
If you don't need support for older browsers, just set the iframe width to 100vw;
iframe {
max-width: 100%; /* Limits width to 100% of container */
width: 100vw; /* Sets width to 100% of the viewport width while respecting the max-width above */
}
Note : Check support for viewport units https://caniuse.com/#feat=viewport-units
Try this
ALTER TABLE Product
ADD ProductID INT NOT NULL DEFAULT(1)
GO
I removed modal backdrop.
.modal-backdrop {
display:none;
}
This is not better solution, but works for me.
Catching an exception while using a Python 'with' statement
The with statement has been available without the __future__
import since Python 2.6. You can get it as early as Python 2.5 (but at this point it's time to upgrade!) with:
from __future__ import with_statement
Here's the closest thing to correct that you have. You're almost there, but with
doesn't have an except
clause:
with open("a.txt") as f: print(f.readlines()) except: # <- with doesn't have an except clause. print('oops')
A context manager's __exit__
method, if it returns False
will reraise the error when it finishes. If it returns True
, it will suppress it. The open
builtin's __exit__
doesn't return True
, so you just need to nest it in a try, except block:
try:
with open("a.txt") as f:
print(f.readlines())
except Exception as error:
print('oops')
And standard boilerplate: don't use a bare except:
which catches BaseException
and every other possible exception and warning. Be at least as specific as Exception
, and for this error, perhaps catch IOError
. Only catch errors you're prepared to handle.
So in this case, you'd do:
>>> try:
... with open("a.txt") as f:
... print(f.readlines())
... except IOError as error:
... print('oops')
...
oops
Here is a trick I have used. It involves adding some CSS properties to make jQuery think the element is visible, but in fact it is still hidden.
var $table = $("#parent").children("table");
$table.css({ position: "absolute", visibility: "hidden", display: "block" });
var tableWidth = $table.outerWidth();
$table.css({ position: "", visibility: "", display: "" });
It is kind of a hack, but it seems to work fine for me.
UPDATE
I have since written a blog post that covers this topic. The method used above has the potential to be problematic since you are resetting the CSS properties to empty values. What if they had values previously? The updated solution uses the swap() method that was found in the jQuery source code.
Code from referenced blog post:
//Optional parameter includeMargin is used when calculating outer dimensions
(function ($) {
$.fn.getHiddenDimensions = function (includeMargin) {
var $item = this,
props = { position: 'absolute', visibility: 'hidden', display: 'block' },
dim = { width: 0, height: 0, innerWidth: 0, innerHeight: 0, outerWidth: 0, outerHeight: 0 },
$hiddenParents = $item.parents().andSelf().not(':visible'),
includeMargin = (includeMargin == null) ? false : includeMargin;
var oldProps = [];
$hiddenParents.each(function () {
var old = {};
for (var name in props) {
old[name] = this.style[name];
this.style[name] = props[name];
}
oldProps.push(old);
});
dim.width = $item.width();
dim.outerWidth = $item.outerWidth(includeMargin);
dim.innerWidth = $item.innerWidth();
dim.height = $item.height();
dim.innerHeight = $item.innerHeight();
dim.outerHeight = $item.outerHeight(includeMargin);
$hiddenParents.each(function (i) {
var old = oldProps[i];
for (var name in props) {
this.style[name] = old[name];
}
});
return dim;
}
}(jQuery));
is that you can make Apache (www-data)
, the owner of the folder
sudo chown -R www-data:www-data /var/www
that should make file_put_contents
work now. But for more security you better also set the permissions like below
find /var/www -type d -print0 | xargs -0 chmod 0755 # folder
find /var/www -type f -print0 | xargs -0 chmod 0644 # files
/var/www
to the root folder of your php filesuse linq
from c in Customers
group c by DbFunctions.TruncateTime(c.CreateTime) into date
orderby date.Key descending
select new
{
Value = date.Count().ToString(),
Name = date.Key.ToString().Substring(0, 10)
}
I had the same problem. Turns out I had two copies of the project and my terminal was in the wrong project folder!
I'd use STUFF
to insert dividing chars and then use CONVERT
with the appropriate style. Something like this:
DECLARE @dt VARCHAR(100)='111290';
SELECT CONVERT(DATETIME,STUFF(STUFF(@dt,3,0,'/'),6,0,'/'),3)
First you use two times STUFF
to get 11/12/90 instead of 111290, than you use the 3 to convert this to datetime
(or any other fitting format: use .
for german, -
for british...) More details on CAST and CONVERT
Best was, to store date and time values properly.
yyyyMMdd
yyyy-MM-dd
or yyyy-MM-ddThh:mm:ss
More details on ISO8601Any culture specific format will lead into troubles sooner or later...
I had old MySQL and Centos OS (ver 6 I believe) that was not supported.
One day I couldn't access Plesk.
Using Filezilla, I copied files the database files from var/lib/mysql/databasename/
I then purchased a new server with new Centos 8 OS and MariaDB.
In Plesk, I created a new database with the same name as my old one.
Using Filezilla, I then pasted the old database files into the newly created database folder. I could see the data in phpmyadmin but it was giving errors such as the ones described here. I happened to have an old sql backup dump file. I imported the dump file and it overwrote those files. I then pasted the old files back into var/lib/mysql/databasename/
I then had to do a repair in Plesk. To my suprise. It worked. I had over 6 months of order data restored and I didn't lose anything.
You can use the dependency-plugin to generate all dependencies in a separate directory before the package phase and then include that in the classpath of the manifest:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>theMainClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
Alternatively use ${project.build.directory}/classes/lib
as OutputDirectory to integrate all jar-files into the main jar, but then you will need to add custom classloading code to load the jars.
Use the Alert Interface, First switchTo()
to alert and then either use accept()
to click on OK or use dismiss()
to CANCEL it
Alert alert_box = driver.switchTo().alert();
alert_box.accept();
or
Alert alert_box = driver.switchTo().alert();
alert_box.dismiss();
Use java-google-translate-text-to-speech instead of Google Translate API v2 Java.
Api unofficial with the main features of Google Translate in Java.
It also provide text to speech api. If you want to translate the text "Hello!" in Romanian just write:
Translator translate = Translator.getInstance();
String text = translate.translate("Hello!", Language.ENGLISH, Language.ROMANIAN);
System.out.println(text); // "Buna ziua!"
As @r0ast3d correctly said:
Important: Google Translate API v2 is now available as a paid service. The courtesy limit for existing Translate API v2 projects created prior to August 24, 2011 will be reduced to zero on December 1, 2011. In addition, the number of requests your application can make per day will be limited.
This is correct: just see the official page:
Google Translate API is available as a paid service. See the Pricing and FAQ pages for details.
BUT, java-google-translate-text-to-speech is FREE!
I've created a sample application that demonstrates that this works. Try it here: https://github.com/IonicaBizau/text-to-speech
<textarea style="resize:none" rows="10" placeholder="Enter Text" ></textarea>
Add -confirm:$false to suppress confirmation.
The problem was that you were using .src
without needing it and
you also needed to differentiate which img
you wanted to change.
function changeImage(a, imgid) {
document.getElementById(imgid).src=a;
}
<div id="main_img">
<img id="img" src="1772031_29_b.jpg">
</div>
<div id="thumb_img">
<img id="1" src='1772031_29_t.jpg' onclick='changeImage("1772031_29_b.jpg", "1");'>
<img id="2" src='1772031_55_t.jpg' onclick='changeImage("1772031_55_b.jpg", "2");'>
<img id="3" src='1772031_53_t.jpg' onclick='changeImage("1772031_53_b.jpg", "3");'>
</div>
Why are the 500 Internal Server Errors not being logged into your apache error logs?
The errors that cause your 500 Internal Server Error are coming from a PHP module. By default, PHP does NOT log these errors. Reason being you want web requests go as fast as physically possible and it's a security hazard to log errors to screen where attackers can observe them.
These instructions to enable Internal Server Error Logging are for Ubuntu 12.10
with PHP 5.3.10
and Apache/2.2.22
.
Make sure PHP logging is turned on:
Locate your php.ini file:
el@apollo:~$ locate php.ini
/etc/php5/apache2/php.ini
Edit that file as root:
sudo vi /etc/php5/apache2/php.ini
Find this line in php.ini:
display_errors = Off
Change the above line to this:
display_errors = On
Lower down in the file you'll see this:
;display_startup_errors
; Default Value: Off
; Development Value: On
; Production Value: Off
;error_reporting
; Default Value: E_ALL & ~E_NOTICE
; Development Value: E_ALL | E_STRICT
; Production Value: E_ALL & ~E_DEPRECATED
The semicolons are comments, that means the lines don't take effect. Change those lines so they look like this:
display_startup_errors = On
; Default Value: Off
; Development Value: On
; Production Value: Off
error_reporting = E_ALL
; Default Value: E_ALL & ~E_NOTICE
; Development Value: E_ALL | E_STRICT
; Production Value: E_ALL & ~E_DEPRECATED
What this communicates to PHP is that we want to log all these errors. Warning, there will be a large performance hit, so you don't want this enabled on production because logging takes work and work takes time, time costs money.
Restarting PHP and Apache should apply the change.
Do what you did to cause the 500 Internal Server error again, and check the log:
tail -f /var/log/apache2/error.log
You should see the 500 error at the end, something like this:
[Wed Dec 11 01:00:40 2013] [error] [client 192.168.11.11] PHP Fatal error:

#since this was yesterday
date -dyesterday +%Y%m%d
#more precise, and more recommended
date -d'27 JUN 2011' +%Y%m%d
#assuming this is similar to yesterdays `date` question from you
#http://stackoverflow.com/q/6497525/638649
date -d'last-monday' +%Y%m%d
#going on @seth's comment you could do this
DATE="27 jun 2011"; date -d"$DATE" +%Y%m%d
#or a method to read it from stdin
read -p " Get date >> " DATE; printf " AS YYYYMMDD format >> %s" `date
-d"$DATE" +%Y%m%d`
#which then outputs the following:
#Get date >> 27 june 2011
#AS YYYYMMDD format >> 20110627
#if you really want to use awk
echo "27 june 2011" | awk '{print "date -d\""$1FS$2FS$3"\" +%Y%m%d"}' | bash
#note | bash just redirects awk's output to the shell to be executed
#FS is field separator, in this case you can use $0 to print the line
#But this is useful if you have more than one date on a line
note this only works on GNU date
I have read that:
Solaris version of date, which is unable to support
-d
can be resolve with replacing sunfreeware.com version of date
