I have tried all of the answers above and it didn't work for me.
In my case when I chekced the log on /usr/local/var/log/postgres.log
. It was fine no error. But I could see that it was listening my local IPV6 address which is "::1"
In my database.yml
I was did it like this
host: <%= ENV['POSTGRESQL_ADDON_HOST'] || '127.0.0.1' %>
I changed it by
host: <%= ENV['POSTGRESQL_ADDON_HOST'] || 'localhost' %>
and then it worked

You need to have file system permission to create the directory.
Example: In Ubuntu 10.04 apache (php) runs as user: www-data in group: www-data
Meaning the user www-data needs access to create the directory.
You can try this yourself by using: 'su www-data' to become the www-data user.
As a quick fix, you can do: sudo chmod 777 my_parent_dir
I have tried with it on Swift 4.2, hopefully it work for you!

If you are passing (like me) all the parameters like port, username, password through a system and you are not allow to modify the code, then you can do that easy change on the web.config

NSTimeInterval
is Double
do do it with extension. Example:
extension Double {
var formattedTime: String {
var formattedTime = "0:00"
if self > 0 {
let hours = Int(self / 3600)
let minutes = Int(truncatingRemainder(dividingBy: 3600) / 60)
formattedTime = String(hours) + ":" + (minutes < 10 ? "0" + String(minutes) : String(minutes))
}
return formattedTime
}
}
Use first the method OpenTextFile
, and then...
either read the file at once with the method ReadAll
:
Set file = fso.OpenTextFile("C:\test.txt", 1)
content = file.ReadAll
or line by line with the method ReadLine
:
Set dict = CreateObject("Scripting.Dictionary")
Set file = fso.OpenTextFile ("c:\test.txt", 1)
row = 0
Do Until file.AtEndOfStream
line = file.Readline
dict.Add row, line
row = row + 1
Loop
file.Close
'Loop over it
For Each line in dict.Items
WScript.Echo line

This occurs when declared (non-pure) virtual functions are missing bodies. In your class definition, something like:
virtual void foo();
Should be defined (inline or in a linked source file):
virtual void foo() {}
Or declared pure virtual:
virtual void foo() = 0;
One thing that could have happened:
Hence, at compile time for the version X, the JVM will generate a first Serial ID (for version X) and it will do the same with the other version Y (another Serial ID).
When your program tries to de-serialize the data, it can't because the two classes do not have the same Serial ID and your program have no guarantee that the two Serialized objects correspond to the same class format.
Assuming you changed your constructor in the mean time and this should make sense to you.
JSX isn't standard JavaScript, based to Airbnb style guide 'eslint' could consider this pattern
// filename: MyComponent.js
function MyComponent() {
return <div />;
}
as a warning, if you named your file MyComponent.jsx it will pass , unless if you edit the eslint rule you can check the style guide here
MSDN has an outline of the purpose of the global.asax file.
Effectively, global.asax allows you to write code that runs in response to "system level" events, such as the application starting, a session ending, an application error occuring, without having to try and shoe-horn that code into each and every page of your site.
You can use it by by choosing Add > New Item > Global Application Class in Visual Studio. Once you've added the file, you can add code under any of the events that are listed (and created by default, at least in Visual Studio 2008):
There are other events that you can also hook into, such as "LogRequest".
This is what I found as I was plotting only 3 cells from each 4 columns lumped together. My chart has a merged cell with the date which is my x axis. The problem: BC26-BE27 are plotting as ZERO on my chart. enter image description here
I click on the filter on the side of the chart and found where it is showing all the columns for which the data points are charted. I unchecked the boxes that do not have values. enter image description here

When it says users are connected, what does the query "select * from pg_stat_activity;" say? Are the other users besides yourself now connected? If so, you might have to edit your pg_hba.conf file to reject connections from other users, or shut down whatever app is accessing the pg database to be able to drop it. I have this problem on occasion in production. Set pg_hba.conf to have a two lines like this:
local all all ident
host all all 127.0.0.1/32 reject
and tell pgsql to reload or restart (i.e. either sudo /etc/init.d/postgresql reload or pg_ctl reload) and now the only way to connect to your machine is via local sockets. I'm assuming you're on linux. If not this may need to be tweaked to something other than local / ident on that first line, to something like host ... yourusername.
Now you should be able to do:
psql postgres
drop database mydatabase;

Just trigger stuff, set some flag, return false. If flag is set - do nothing.
This will do the job:

cout << i << endl;
if (num/i!=i)
cout << num/i << endl;

Form elements can be accessed via the form's DOM element by name, not by "id" value. Give your form elements names if you want to access them like that, or else access them directly by "id" value:
document.getElementById("color").disabled = true;
edit — oh also, as pointed out by others, it's just "text", not "TextBox", for the "type" attribute.
You might want to invest a little time in reading some front-end development tutorials.
Another way to refresh the current page using selenium in Java.
//first: get the current URL in a String variable
String currentURL = driver.getCurrentUrl();
//second: call the current URL
driver.get(currentURL);
Using this will refresh the current page like clicking the address bar of the browser and pressing enter.
The max length property is camel-cased: maxLength
jQuery doesn't come with a maxlength method by default. Also, your document ready function isn't technically correct:
$(document).ready(function () {
$("#ms_num")[0].maxLength = 6;
// OR:
$("#ms_num").attr('maxlength', 6);
// OR you can use prop if you are using jQuery 1.6+:
$("#ms_num").prop('maxLength', 6);
});
Also, since you are using jQuery, you can rewrite your code like this (taking advantage of jQuery 1.6+):
$('input').each(function (index) {
var element = $(this);
if (index === 1) {
element.prop('maxLength', 3);
} else if (element.is(':radio') || element.is(':checkbox')) {
element.prop('maxLength', 5);
}
});
$(function() {
$("#ms_num").prop('maxLength', 6);
});
I would just like to throw the idea of annotation : @getter and @setter. With @getter, you should be able to obj = class.field but not class.field = obj. With @setter, vice versa. With @getter and @setter you should be able to do both. This would preserve encapsulation and reduce the time by not calling trivial methods at runtime.
For information MCRYPT_MODE_ECB
doesn't use the IV (initialization vector). ECB mode divide your message into blocks and each block is encrypted separately. I really don't recommended it.
CBC mode use the IV to make each message unique. CBC is recommended and should be used instead of ECB.
Example :
<?php
$password = "myPassword_!";
$messageClear = "Secret message";
// 32 byte binary blob
$aes256Key = hash("SHA256", $password, true);
// for good entropy (for MCRYPT_RAND)
srand((double) microtime() * 1000000);
// generate random iv
$iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CBC), MCRYPT_RAND);
$crypted = fnEncrypt($messageClear, $aes256Key);
$newClear = fnDecrypt($crypted, $aes256Key);
echo
"IV: <code>".$iv."</code><br/>".
"Encrypred: <code>".$crypted."</code><br/>".
"Decrypred: <code>".$newClear."</code><br/>";
function fnEncrypt($sValue, $sSecretKey) {
global $iv;
return rtrim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $sSecretKey, $sValue, MCRYPT_MODE_CBC, $iv)), "\0\3");
}
function fnDecrypt($sValue, $sSecretKey) {
global $iv;
return rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $sSecretKey, base64_decode($sValue), MCRYPT_MODE_CBC, $iv), "\0\3");
}
You have to stock the IV to decode each message (IV are not secret). Each message is unique because each message has an unique IV.
If you are running your script at linux environment you can use this command:
bsub -q server_name -R "rusage[mem=requested_memory]" "Rscript script_name.R"
and the server will allocate the requested memory for you (according to the server limits, but with good server - hugefiles can be used)
From SourceTree, click on Tools->Options. Then on the "General" tab, make sure to check the box to allow SourceTree to modify your Git config files.
Then switch to the "Diff" tab. On the lower half, use the drop down to select the external program you want to use to do the diffs and merging. I've installed KDiff3 and like it well enough. When you're done, click OK.
Now when there is a merge, you can go under Actions->Resolve Conflicts->Launch External Merge Tool.
This is what worked for me on Windows. The cause being multiple python installations

Use a for
loop instead of .forEach()
var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false
for(var call of myObj) {
console.log(call)
var a = call['a'], b = call['b']
if(a == null || b == null) {
result = false
break
}
}
Almost certainly, your reuse identifier "title"
is incorrect.
We can see from the UITableView.h
method signature of dequeueReusableCellWithIdentifier
that the return type is an Implicitly Unwrapped Optional:
func dequeueReusableCellWithIdentifier(identifier: String!) -> AnyObject! // Used by the delegate to acquire an already allocated cell, in lieu of allocating a new one.
That's determined by the exclamation mark after AnyObject
:
AnyObject!
So, first thing to consider is, what is an "Implicitly Unwrapped Optional"?
The Swift Programming Language tells us:
Sometimes it is clear from a program’s structure that an optional will always have a value, after that value is first set. In these cases, it is useful to remove the need to check and unwrap the optional’s value every time it is accessed, because it can be safely assumed to have a value all of the time.
These kinds of optionals are defined as implicitly unwrapped optionals. You write an implicitly unwrapped optional by placing an exclamation mark (String!) rather than a question mark (String?) after the type that you want to make optional.
So, basically, something that might have been nil at one point, but which from some point on is never nil again. We therefore save ourselves some bother by taking it in as the unwrapped value.
It makes sense in this case for dequeueReusableCellWithIdentifier
to return such a value. The supplied identifier must have already been used to register the cell for reuse. Supply an incorrect identifier, the dequeue can't find it, and the runtime returns a nil that should never happen. It's a fatal error, the app crashes, and the Console output gives:
fatal error: unexpectedly found nil while unwrapping an Optional value
Bottom line: check your cell reuse identifier specified in the .storyboard, Xib, or in code, and ensure that it is correct when dequeuing.
Escape sequences (and variables too) work inside double quoted and heredoc strings. So change your code to:
echo '<p>' . $unit1 . "</p>\n";
PS: One clarification, single quotes strings do accept two escape sequences:
\'
when you want to use single quote inside single quoted strings\\
when you want to use backslash literallyI had some dealings with the select \ multi-select this is what did the trick for me
<select name="mySelect" multiple="multiple">
<option>Foo</option>
<option>Bar</option>
<option>Foo Bar</option>
<option>Bar Foo</option>
</select>

Both of these functions look equally valid in terms of reading cookie. You can shave a few bytes off though (and it really is getting into Code Golf territory here):
function readCookie(name) {
var nameEQ = name + "=", ca = document.cookie.split(';'), i = 0, c;
for(;i < ca.length;i++) {
c = ca[i];
while (c[0]==' ') c = c.substring(1);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length);
}
return null;
}
All I did with this is collapse all the variable declarations into one var statement, removed the unnecessary second arguments in calls to substring, and replace the one charAt call into an array dereference.
This still isn't as short as the second function you provided, but even that can have a few bytes taken off:
function read_cookie(key)
{
var result;
return (result = new RegExp('(^|; )' + encodeURIComponent(key) + '=([^;]*)').exec(document.cookie)) ? result[2] : null;
}
I changed the first sub-expression in the regular expression to be a capturing sub-expression, and changed the result[1] part to result[2] to coincide with this change; also removed the unnecessary parens around result[2].
Wrap the name in a span, give it a class and assign a style to that class:
<td><span class="names">Name text you want bold</span> rest of your text</td>
style:
.names { font-weight: bold; }

If during installation of a plugin, Wordpress asks for your hostname or FTP details. Then follow these steps:
Login to your server and navigate to /var/www/html/wordpress/. Open wp-config.php and add this line after define(‘DB_COLLATE’)
define('FS_METHOD', 'direct');
If you get "Could not create directory" error. Give write permissions to your wordpress directory in recursive as
chmod -R go+w wordpress
NOTE. For security, revoke these permissions once you install a plugin as
chmod -R go-w wordpress
Another option is to do another "git stash" of the local uncommitted changes, then combine the two git stashes. Unfortunately git seems to not have a way to easily combine two stashes. So one option is to create two .diff files and apply them both--at lest its not an extra commit and doesn't involve a ten step process :|
I was checking all the answer above and wanted to add one more additional information. I wanted to sort the list in DESC order and I was searching for the solution which is faster for bigger inputs and I was using this method earlier :-
li.Sort();
li.Reverse();
but my test cases were failing for exceeding time limits, so below solution worked for me:-
li.Sort((a, b) => b.CompareTo(a));
So Ultimately the conclusion is that 2nd way of Sorting list in Descending order is bit faster than the previous one.
The short answer is for creating an attribute in c# you only need to inherit it from Attribute class, Just this :)
But here I'm going to explain attributes in detail:
basically attributes are classes that we can use them for applying our logic to assemblies, classes, methods, properties, fields, ...
In .Net, Microsoft has provided some predefined Attributes like Obsolete or Validation Attributes like ( [Required], [StringLength(100)], [Range(0, 999.99)]), also we have kind of attributes like ActionFilters in asp.net that can be very useful for applying our desired logic to our codes (read this article about action filters if you are passionate to learn it)
one another point, you can apply a kind of configuration on your attribute via AttibuteUsage.
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple = true)]
When you decorate an attribute class with AttributeUsage you can tell to c# compiler where I'm going to use this attribute: I'm going to use this on classes, on assemblies on properties or on ... and my attribute is allowed to use several times on defined targets(classes, assemblies, properties,...) or not?!
After this definition about attributes I'm going to show you an example: Imagine we want to define a new lesson in university and we want to allow just admins and masters in our university to define a new Lesson, Ok?
namespace ConsoleApp1

/// <summary>
/// All Roles in our scenario

{
public ValidRoleForAccess(UniversityRoles role)
{
Role = role;
}
public UniversityRoles Role { get; private set; }

throw new Exception("You are not Allowed to define a new lesson");
}

In the real world of programming maybe we don't use this approach for using attributes and I said this because of its educational point in using attributes
Note that const declarations are block-scoped.
const el: HTMLElement | null = document.getElementById('content');
if (el) {
const definitelyAnElement: HTMLElement = el;
}
So the value of definitelyAnElement is not accessible outside of the {}.
(I would have commented above, but I do not have enough Reputation apparently.)
Ran a benchmark, and it turns out the fastest way of getting a real integer (using all the available methods) is
$foo = (int)+"12.345";
Just using
$foo = +"12.345";
returns a float.

VT-x can normally be disabled/enabled in your BIOS.
When your PC is just starting up you should press DEL (or something) to get to the BIOS settings. There you'll find an option to enable VT-technology (or something).
In your version rand() % 10000
will yield an integer between 0
and 9999
. Since RAND_MAX may be as little as 32767, and since this is not exactly divisible by 10000 and not large relative to 10000, there will be significant bias in the 'randomness' of the result, moreover, the maximum value will be 0.9999, not 1.0, and you have unnecessarily restricted your values to four decimal places.
It is simple arithmetic, a random number divided by the maximum possible random number will yield a number from 0 to 1 inclusive, while utilising the full resolution and distribution of the RNG
double r2()
{
return (double)rand() / (double)RAND_MAX ;
}
Use (double)rand() / (double)((unsigned)RAND_MAX + 1)
if exclusion of 1.0 was intentional.
Just noticed that quick search has been included into eclipse 4.13 as a built-in function by typing Ctrl+Alt+Shift+L (or Cmd+Alt+Shift+L on Mac)
https://www.eclipse.org/eclipse/news/4.13/platform.php#quick-text-search
I don't think you have data for every single day for the past seven days. Days for which no data exist, will obviously not show up.
Try this and validate that you have data for EACH day for the past 7 days
SELECT DISTINCT CreatedDate
FROM News
WHERE CreatedDate >= DATEADD(day,-7, GETDATE())
ORDER BY CreatedDate
EDIT - Copied from your comment
i have dec 19th -1 row data,18th -2 rows,17th -3 rows,16th -3 rows,15th -3 rows,12th -2 rows, 11th -4 rows,9th -1 row,8th -1 row
You don't have data for all days. That is your problem and not the query. If you execute the query today - 22nd - you will only get data for 19th, 18th,17th,16th and 15th. You have no data for 20th, 21st and 22nd.
EDIT - To get data for the last 7 days, where data is available you can try
select id,
NewsHeadline as news_headline,
NewsText as news_text,
state,
CreatedDate as created_on
from News
WHERE CreatedDate IN (SELECT DISTINCT TOP 7 CreatedDate from News
order by createddate DESC)
From your above needs, you will need to use both Python (to export pandas data frame) and VBA (to delete existing worksheet content and copy/paste external data).
With Python: use the to_csv or to_excel methods. I recommend the to_csv method which performs better with larger datasets.
# DF TO EXCEL
from pandas import ExcelWriter
writer = ExcelWriter('PythonExport.xlsx')
yourdf.to_excel(writer,'Sheet5')
writer.save()
# DF TO CSV
yourdf.to_csv('PythonExport.csv', sep=',')
With VBA: copy and paste source to destination ranges.
Fortunately, in VBA you can call Python scripts using Shell (assuming your OS is Windows).
Sub DataFrameImport()
'RUN PYTHON TO EXPORT DATA FRAME
Shell "C:\pathTo\python.exe fullpathOfPythonScript.py", vbNormalFocus
'CLEAR EXISTING CONTENT
ThisWorkbook.Worksheets(5).Cells.Clear
'COPY AND PASTE TO WORKBOOK
Workbooks("PythonExport").Worksheets(1).Cells.Copy
ThisWorkbook.Worksheets(5).Range("A1").Select
ThisWorkbook.Worksheets(5).Paste
End Sub
Alternatively, you can do vice versa: run a macro (ClearExistingContent) with Python. Be sure your Excel file is a macro-enabled (.xlsm) one with a saved macro to delete Sheet 5 content only. Note: macros cannot be saved with csv files.
import os
import win32com.client
from pandas import ExcelWriter
if os.path.exists("C:\Full Location\To\excelsheet.xlsm"):
xlApp=win32com.client.Dispatch("Excel.Application")
wb = xlApp.Workbooks.Open(Filename="C:\Full Location\To\excelsheet.xlsm")
# MACRO TO CLEAR SHEET 5 CONTENT
xlApp.Run("ClearExistingContent")
wb.Save()
xlApp.Quit()
del xl
# WRITE IN DATA FRAME TO SHEET 5
writer = ExcelWriter('C:\Full Location\To\excelsheet.xlsm')
yourdf.to_excel(writer,'Sheet5')
writer.save()
The JSON.stringify
method supported by many modern browsers (including IE8) can output a beautified JSON string:
JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4); // stringify with 4 spaces at each level
Demo: http://jsfiddle.net/AndyE/HZPVL/
This method is also included with json2.js, for supporting older browsers.
If you don't need to do it programmatically, Try JSON Lint. Not only will it prettify your JSON, it will validate it at the same time.
Unfortunately there is no hung state for a process. Now hung can be deadlock. This is block state. The threads in the process are blocked. The other things could be live lock where the process is running but doing the same thing again and again. This process is in running state. So as you can see there is no definite hung state. As suggested you can use the top command to see if the process is using 100% CPU or lot of memory.

CURLOPT_USERPWD
basically sends the base64 of the user:password
string with http header like below:
Authorization: Basic dXNlcjpwYXNzd29yZA==
So apart from the CURLOPT_USERPWD
you can also use the HTTP-Request
header option as well like below with other headers:
$headers = array(
'Content-Type:application/json',
'Authorization: Basic '. base64_encode("user:password") // <---
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
In C ++, if a const object is initialized with a constant expression, we can use our const object wherever a constant expression is required.
const int x = 10;
int a[x] = {0};
For example, we can make a case statement in switch.
constexpr can be used with arrays.
constexpr is not a type.
The constexpr keyword can be used in conjunction with the auto keyword.
constexpr auto x = 10;
struct Data { // We can make a bit field element of struct.
int a:x;
};
If we initialize a const object with a constant expression, the expression generated by that const object is now a constant expression as well.
Constant Expression : An expression whose value can be calculated at compile time.
x*5-4 // This is a constant expression. For the compiler, there is no difference between typing this expression and typing 46 directly.
Initialize is mandatory. It can be used for reading purposes only. It cannot be changed. Up to this point, there is no difference between the "const" and "constexpr" keywords.
NOTE: We can use constexpr and const in the same declaration.
constexpr const int* p;
Normally, the return value of a function is obtained at runtime. But calls to constexpr functions will be obtained as a constant in compile time when certain conditions are met.
NOTE : Arguments sent to the parameter variable of the function in function calls or to all parameter variables if there is more than one parameter, if C.E the return value of the function will be calculated in compile time. !!!
constexpr int square (int a){
return a*a;
}
constexpr int a = 3;
constexpr int b = 5;
int arr[square(a*b+20)] = {0}; //This expression is equal to int arr[35] = {0};
In order for a function to be a constexpr function, the return value type of the function and the type of the function's parameters must be in the type category called "literal type".
The constexpr functions are implicitly inline functions.
None of the constexpr functions need to be called with a constant expression.It is not mandatory. If this happens, the computation will not be done at compile time. It will be treated like a normal function call. Therefore, where the constant expression is required, we will no longer be able to use this expression.
1 ) The types used in the parameters of the function and the type of the return value of the function must be literal type.
2 ) A local variable with static life time should not be used inside the function.
3 ) If the function is legal, when we call this function with a constant expression in compile time, the compiler calculates the return value of the function in compile time.
4 ) The compiler needs to see the code of the function, so constexpr functions will almost always be in the header files.
5 ) In order for the function we created to be a constexpr function, the definition of the function must be in the header file.Thus, whichever source file includes that header file will see the function definition.
Normally with Default Member Initialization, static data members with const and integral types can be initialized within the class. However, in order to do this, there must be both "const" and "integral types".
If we use static constexpr then it doesn't have to be an integral type to initialize it inside the class. As long as I initialize it with a constant expression, there is no problem.
class Myclass {
const static int sx = 15; // OK
constexpr static int sy = 15; // OK
const static double sd = 1.5; // ERROR
constexpr static double sd = 1.5; // OK
};
It's impossible, and for a good reason (for one, think about all those catch(Exception){} around).
If you want to continue execution after stack overflow, run dangerous code in a different AppDomain. CLR policies can be set to terminate current AppDomain on overflow without affecting original domain.
To get the job done, use
<table cellspacing=12>
If you’d rather “be right” than get things done, you can instead use the CSS property border-spacing
, which is supported by some browsers.
This is an implementation of aforementioned StanLe's anwer, also fixing the case where his answer would produce no curve when using densities.
This replaces the existing but hidden hist.default()
function, to only add the normalcurve
parameter (which defaults to TRUE
).
The first three lines are to support roxygen2 for package building.
#' @noRd
#' @exportMethod hist.default
#' @export
hist.default <- function(x,
breaks = "Sturges",
freq = NULL,
include.lowest = TRUE,
normalcurve = TRUE,
right = TRUE,
density = NULL,
angle = 45,
col = NULL,
border = NULL,
main = paste("Histogram of", xname),
ylim = NULL,
xlab = xname,
ylab = NULL,
axes = TRUE,
plot = TRUE,
labels = FALSE,
warn.unused = TRUE,
...) {
# https://stackoverflow.com/a/20078645/4575331
xname <- paste(deparse(substitute(x), 500), collapse = "\n")
suppressWarnings(
h <- graphics::hist.default(
x = x,
breaks = breaks,
freq = freq,
include.lowest = include.lowest,
right = right,

...
)
)
if (normalcurve == TRUE & plot == TRUE) {
x <- x[!is.na(x)]
xfit <- seq(min(x), max(x), length = 40)
yfit <- dnorm(xfit, mean = mean(x), sd = sd(x))
if (isTRUE(freq) | (is.null(freq) & is.null(density))) {
yfit <- yfit * diff(h$mids[1:2]) * length(x)
}
lines(xfit, yfit, col = "black", lwd = 2)
}
if (plot == TRUE) {
invisible(h)
} else {
h
}
}
Quick example:
hist(g)
For dates it's bit different. For reference:
#' @noRd
#' @exportMethod hist.Date
#' @export
hist.Date <- function(x,
breaks = "months",
format = "%b",
normalcurve = TRUE,
xlab = xname,
plot = TRUE,

density = NULL,
start.on.monday = TRUE,
right = TRUE,
...) {
# https://stackoverflow.com/a/20078645/4575331
xname <- paste(deparse(substitute(x), 500), collapse = "\n")
suppressWarnings(
h <- graphics:::hist.Date(
x = x,
breaks = breaks,
format = format,
freq = freq,
density = density,
start.on.monday = start.on.monday,
right = right,
xlab = xlab,
plot = plot,
...
)
)
if (normalcurve == TRUE & plot == TRUE) {
x <- x[!is.na(x)]
xfit <- seq(min(x), max(x), length = 40)
yfit <- dnorm(xfit, mean = mean(x), sd = sd(x))
if (isTRUE(freq) | (is.null(freq) & is.null(density))) {
yfit <- as.double(yfit) * diff(h$mids[1:2]) * length(x)
}
lines(xfit, yfit, col = "black", lwd = 2)
}
if (plot == TRUE) {
invisible(h)
} else {
h
}
}
You need both a value and a field to assign it to. The value is TableField + 1
, so the assignment is:
SET TableField = TableField + 1
May be this is alltime multiple connection open issue, you are somewhere in your code opening connections and not closing them properly. use

I am totally noob at Linux, I just wanted to update Python from 2.x to 3.x so that Platformio could upgrade and now I messed up everything it seems.
The standard solution:
expr $d1 - $d2
You can also do:
echo $(( d1 - d2 ))
but beware that this will treat 07
as an octal number! (so 07
is the same as 7
, but 010
is different than 10
).
How to validate file extension (jpg/jpeg only) on a form before upload takes place. A variation on another posted answer here with an included data filter which may be useful when evaluating other posted form values. Note: error is left blank if empty as this was an option for my users, not a requirement.
<?php
if(isset($_POST['save'])) {
//Validate image
if (empty($_POST["image"])) {
$imageError = "";
} else {
$image = test_input($_POST["image"]);
$allowed = array('jpeg','jpg');
$ext = pathinfo($image, PATHINFO_EXTENSION);
if(!in_array($ext,$allowed) ) {
$imageError = "jpeg only";
}
}
}
// Validate data
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
<?
Your html will look something like this;
<html>
<head>
</head>
<body>
<!-- Validate -->
<?php include_once ('validate.php'); ?>
<!-- Form -->
<form method="post" action="">
<!-- Image -->
<p>Image <?php echo $imageError; ?></p>
<input type="file" name="image" value="<?php echo $image; ?>" />
<p><input type="submit" name="save" value="SAVE" /></p>
</form>
</body>
</html>
Adapted from this answer to a very similar question:
FORFILES /S /D -10 /C "cmd /c IF @isdir == TRUE rd /S /Q @path"
You should run this command from within your d:\study
folder. It will delete all subfolders which are older than 10 days.
The /S /Q
after the rd
makes it delete folders even if they are not empty, without prompting.
I suggest you put the above command into a .bat file, and save it as d:\study\cleanup.bat
.
Simply change encoding of loaded file in IntelliJ IDEA IDE, on the right of status bar (bottom), where current charset is indicated. It prompts to Reload or Convert, use Convert. Make sure you backed up original file in advance.
I did it this way and it worked for me like a charm.
var data = [{ id: 0, text: 'enhancement' }, { id: 1, text: 'bug' }, { id: 2,
text: 'duplicate' }, { id: 3, text: 'invalid' }, { id: 4, text: 'wontfix' }];
$(".js-example-data-array").select2({
data: data
})
If the behavior of for(... in ...) is acceptable/necessary for your purposes, you can tell tslint to allow it.
in tslint.json, add this to the "rules" section.
"forin": false
Otherwise, @Maxxx has the right idea with
for (const field of Object.keys(this.formErrors)) {
I had the same issue and I resolved it by making changes in the UnityConfig.cs file In order to resolve the dependency issue in the UnityConfig.cs file you have to add:
public static void RegisterComponents()
{
var container = new UnityContainer();
container.RegisterType<ITestService, TestService>();
DependencyResolver.SetResolver(new UnityDependencyResolver(container));
}
I think this gives you the total list of all files in the repo history:
git rev-list --objects --all | git cat-file --batch-check="%(objectsize) %(rest)" | cut -d" " -f1 | paste -s -d + - | bc
You can replace --all
with a treeish (HEAD
, origin/master
, etc.) to calculate the size of a branch.
You can use data-*
attribute to embed custom data. The data-*
attributes gives us the ability to embed custom data attributes on all HTML elements.
jQuery .data()
method allows you to get/set data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks.
jQuery .attr()
method get/set attribute value for only the first element in the matched set.
Example:
<span id="test" title="foo" data-kind="primary">foo</span>
$("#test").attr("title");
$("#test").attr("data-kind");
$("#test").data("kind");
$("#test").data("value", "bar");
There are non-obvious memory retention issues to take into account here. Since a non-static inner class maintains an implicit reference to it's 'outer' class, if an instance of the inner class is strongly referenced, then the outer instance is strongly referenced too. This can lead to some head-scratching when the outer class is not garbage collected, even though it appears that nothing references it.
A cookie is simply a short text string that is sent back and forth between the client and the server. You could store name=bob; password=asdfas
in a cookie and send that back and forth to identify the client on the server side. You could think of this as carrying on an exchange with a bank teller who has no short term memory, and needs you to identify yourself for each and every transaction. Of course using a cookie to store this kind information is horrible insecure. Cookies are also limited in size.
Now, when the bank teller knows about his/her memory problem, He/She can write down your information on a piece of paper and assign you a short id number. Then, instead of giving your account number and driver's license for each transaction, you can just say "I'm client 12"
Translating that to Web Servers: The server will store the pertinent information in the session object, and create a session ID which it will send back to the client in a cookie. When the client sends back the cookie, the server can simply look up the session object using the ID. So, if you delete the cookie, the session will be lost.
One other alternative is for the server to use URL rewriting to exchange the session id.
Suppose you had a link - www.myserver.com/myApp.jsp
You could go through the page and rewrite every URL as www.myserver.com/myApp.jsp?sessionID=asdf
or even www.myserver.com/asdf/myApp.jsp
and exchange the identifier that way. This technique is handled by the web application container and is usually turned on by setting the configuration to use cookieless sessions.
public static String[] getStringArray(JSONArray jsonArray) {
String[] stringArray = null;
if (jsonArray != null) {
int length = jsonArray.length();
stringArray = new String[length];
for (int i = 0; i < length; i++) {
stringArray[i] = jsonArray.optString(i);
}
}
return stringArray;
}
You can try something similar to this :
String s = "65";
byte value = Byte.valueOf(s);
Use the Byte.ValueOf()
method for all the elements in the String array to convert them into Byte values.
I know that this is an old question, but as I was googling it was the first link in a results. So here is the jsp solution:
<form action="some.jsp">
<select name="item">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<input type="submit" value="Submit">
</form>
in some.jsp
request.getParameter("item");
this line will return the selected option (from the example it is: 1, 2 or 3)
A lot of these answers are pretty old, so I thought I would update with a solution that I think is helpful.
Our issue was similar to OP's, we upgraded 32 bit XP machines to 64 bit windows 7 and our application software that uses a 32 bit ODBC driver stopped being able to write to our database.
Turns out, there are two ODBC Data Source Managers, one for 32 bit and one for 64 bit. So I had to run the 32 bit version which is found in C:\Windows\SysWOW64\odbcad32.exe. Inside the ODBC Data Source Manager, I was able to go to the System DSN tab and Add my driver to the list using the Add button. (You can check the Drivers tab to see a list of the drivers you can add, if your driver isn't in this list then you may need to install it).
The next issue was the software that we ran was compiled to use 'Any CPU'. This would see the operating system was 64 bit, so it would look at the 64 bit ODBC Data Sources. So I had to force the program to compile as an x86 program, which then tells it to look at the 32 bit ODBC Data Sources. To set your program to x86, in Visual Studio go to your project properties and under the build tab at the top there is a platform drop down list, and choose x86. If you don't have the source code and can't compile the program as x86, you might be able to right click the program .exe and go to the compatibility tab and choose a compatibility that works for you.
Once I had the drivers added and the program pointing to the right drivers, everything worked like it use to. Hopefully this helps anyone working with older software.
The simple way to do your test is :
function (data) {
if (data) { // check if null, undefined, empty ...
// some code here
}
}
This worked for me (though it's for reactjs & tachyons used as inline CSS)
<div className="pa2 cf vh-100-ns" style={{backgroundImage: `url(${a6})`}}>
........
</div>
This takes in css as height: 100vh
To write it with a while loop you can do:
ls -f /var | while read -r file; do cmd $file; done
The primary disadvantage of this is that cmd is run in a subshell, which causes some difficulty if you are trying to set variables. The main advantages are that the shell does not need to load all of the filenames into memory, and there is no globbing. When you have a lot of files in the directory, those advantages are important (that's why I use -f on ls; in a large directory ls itself can take several tens of seconds to run and -f speeds that up appreciably. In such cases 'for file in /var/*' will likely fail with a glob error.)

Based on the @MixerOID response, here is my final solution as a component (maybe I create a library). I also support FormArray's:
import {Component, ElementRef, Input, OnInit} from '@angular/core';
import {FormArray, FormGroup, ValidationErrors} from '@angular/forms';
import {TranslateService} from '@ngx-translate/core';
interface AllValidationErrors {
controlName: string;
errorName: string;
errorValue: any;
}
@Component({
selector: 'app-form-errors',
templateUrl: './form-errors.component.html',
styleUrls: ['./form-errors.component.scss']
})
export class FormErrorsComponent implements OnInit {
@Input() form: FormGroup;
@Input() formRef: ElementRef;
@Input() messages: Array<any>;
private errors: AllValidationErrors[];
constructor(
private translateService: TranslateService
) {
this.errors = [];
this.messages = [];
}
ngOnInit() {
this.form.valueChanges.subscribe(() => {
this.errors = [];
this.calculateErrors(this.form);
});
this.calculateErrors(this.form);
}
calculateErrors(form: FormGroup | FormArray) {
Object.keys(form.controls).forEach(field => {
const control = form.get(field);
if (control instanceof FormGroup || control instanceof FormArray) {
this.errors = this.errors.concat(this.calculateErrors(control));
return;
}
const controlErrors: ValidationErrors = control.errors;
if (controlErrors !== null) {
Object.keys(controlErrors).forEach(keyError => {
this.errors.push({
controlName: field,
errorName: keyError,
errorValue: controlErrors[keyError]
});
});
}
});
// This removes duplicates
this.errors = this.errors.filter((error, index, self) => self.findIndex(t => {
return t.controlName === error.controlName && t.errorName === error.errorName;
}) === index);
return this.errors;
}
getErrorMessage(error) {
switch (error.errorName) {
case 'required':
return this.translateService.instant('mustFill') + ' ' + this.messages[error.controlName];
default:
return 'unknown error ' + error.errorName;
}
}
}
And the HTML:
<div *ngIf="formRef.submitted">
<div *ngFor="let error of errors" class="text-danger">
{{getErrorMessage(error)}}
</div>
</div>
Usage:
<app-form-errors [form]="languageForm"
[formRef]="formRef"
[messages]="{language: 'Language'}">

What's the problem , in fact ?
If you really need or want 10 a, b, c, d, e, f, g, h, i, j , there will be no other possibility, at a time or another, to write a and write b and write c.....
If the values are all different, you will be obliged to write for exemple
a = 12
b= 'sun'
c = A() #(where A is a class)
d = range(1,102,5)
e = (line in filehandler if line.rstrip())
f = 0,12358
g = True
h = random.choice
i = re.compile('^(!= ab).+?<span>')
j = [78,89,90,0]
that is to say defining the "variables" individually.
Or , using another writing, no need to use _
:
a,b,c,d,e,f,g,h,i,j =\
12,'sun',A(),range(1,102,5),\
(line for line in filehandler if line.rstrip()),\
0.12358,True,random.choice,\
re.compile('^(!= ab).+?<span>'),[78,89,90,0]
or
a,b,c,d,e,f,g,h,i,j =\
(12,'sun',A(),range(1,102,5),
(line for line in filehandler if line.rstrip()),
0.12358,True,random.choice,
re.compile('^(!= ab).+?<span>'),[78,89,90,0])
.
If some of them must have the same value, is the problem that it's too long to write
a, b, c, d, e, f, g, h, i, j = True, True, True, True, True, False, True ,True , True, True
?
Then you can write:
a=b=c=d=e=g=h=i=k=j=True
f = False
.
I don't understand what is exactly your problem. If you want to write a code, you're obliged to use the characters required by the writing of the instructions and definitions. What else ?
I wonder if your question isn't the sign that you misunderstand something.
When one writes a = 10
, one don't create a variable in the sense of "chunk of memory whose value can change". This instruction:
either triggers the creation of an object of type integer
and value 10 and the binding of a name 'a' with this object in the current namespace
or re-assign the name 'a' in the namespace to the object 10 (because 'a' was precedently binded to another object)
I say that because I don't see the utility to define 10 identifiers a,b,c... pointing to False or True. If these values don't change during the execution, why 10 identifiers ? And if they change, why defining the identifiers first ?, they will be created when needed if not priorly defined
Your question appears weird to me

The below solution worked for me for the core-plot 2.3 version. Do the below changes under other linker flags section.
1.Add $(inherited) and drag this item to top position 2.Remove "Pods-" prefix from -l"Pods-fmemopen”, l"Pods-NSAttributedStringMarkdownParser” and -l"Pods-MagicalRecord”.
if still issue persists, Finally see if PODS_ROOT is set or not. You can check it under user defined section.
From a background script you can listen to the chrome.tabs.onUpdated
event and check the property changeInfo.status
on the callback. It can be loading or complete. If it is complete, do the action.
Example:
chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
if (changeInfo.status == 'complete') {
// do your things
}
})
Because this will probably trigger on every tab completion, you can also check if the tab is active
on its homonymous attribute, like this:
chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
if (changeInfo.status == 'complete' && tab.active) {
// do your things
}
})
For infinite scrolling with days it's important you have the good fragment in the pager therefore I wrote my answer on this on page (Viewpager in Android to switch between days endlessly)
It's working very well! Above answers did not work for me as I wanted it to work.
It means:
'O' (Python) objects
The first character specifies the kind of data and the remaining characters specify the number of bytes per item, except for Unicode, where it is interpreted as the number of characters. The item size must correspond to an existing type, or an error will be raised. The supported kinds are to an existing type, or an error will be raised. The supported kinds are:
'b' boolean
'i' (signed) integer
'u' unsigned integer
'f' floating-point
'c' complex-floating point
'O' (Python) objects
'S', 'a' (byte-)string
'U' Unicode
'V' raw data (void)
Another answer helps if need check type
s.
Also worth noting you can use 'em' as well as 'px' - blogs and text based sites do it because then the browser makes layout decisions more relative to the text content.

The most common reason for this message seems to be unzipping the eclipse zip file wrongly (for instance unzipping without recreating the directory structure). Therefore please unzip the zipped Eclipse again with a good unzip tool (like 7-zip) and make sure that the necessary sub directories are created during the extraction.
Also make sure that the path to the unzipped Eclipse does not get very long. I've seen cases where Eclipse was unzipped into a deeply nested directory structure (to put it at some place into an SVN repository) and that led to the same error message.
If that still doesn't work, you may try launching eclipse.exe with administrative rights. That should not really be necessary, but maybe your access rights are somehow broken after the re-installation of Windows.
I'm writing an updated answer for Python 3 to this question.
How is
__eq__
handled in Python and in what order?a == b
It is generally understood, but not always the case, that a == b
invokes a.__eq__(b)
, or type(a).__eq__(a, b)
.
Explicitly, the order of evaluation is:
b
's type is a strict subclass (not the same type) of a
's type and has an __eq__
, call it and return the value if the comparison is implemented,a
has __eq__
, call it and return it if the comparison is implemented,__eq__
and it has it, then call and return it if the comparison is implemented,is
.We know if a comparison isn't implemented if the method returns NotImplemented
.
(In Python 2, there was a __cmp__
method that was looked for, but it was deprecated and removed in Python 3.)
Let's test the first check's behavior for ourselves by letting B subclass A, which shows that the accepted answer is wrong on this count:
class A:
value = 3
def __eq__(self, other):
print('A __eq__ called')
return self.value == other.value
class B(A):
value = 4
def __eq__(self, other):
print('B __eq__ called')
return self.value == other.value
a, b = A(), B()
a == b
which only prints B __eq__ called
before returning False
.
The other answers here seem incomplete and out of date, so I'm going to update the information and show you how how you could look this up for yourself.
This is handled at the C level.
We need to look at two different bits of code here - the default __eq__
for objects of class object
, and the code that looks up and calls the __eq__
method regardless of whether it uses the default __eq__
or a custom one.
__eq__
Looking __eq__
up in the relevant C api docs shows us that __eq__
is handled by tp_richcompare
- which in the "object"
type definition in cpython/Objects/typeobject.c
is defined in object_richcompare
for case Py_EQ:
.
case Py_EQ:
/* Return NotImplemented instead of False, so if two
objects are compared, both get a chance at the
comparison. See issue #1393. */
res = (self == other) ? Py_True : Py_NotImplemented;
Py_INCREF(res);
break;
So here, if self == other
we return True
, else we return the NotImplemented
object. This is the default behavior for any subclass of object that does not implement its own __eq__
method.
__eq__
gets calledThen we find the C API docs, the PyObject_RichCompare function, which calls do_richcompare
.
Then we see that the tp_richcompare
function, created for the "object"
C definition is called by do_richcompare
, so let's look at that a little more closely.
The first check in this function is for the conditions the objects being compared:
__eq__
method,then call the other's method with the arguments swapped, returning the value if implemented. If that method isn't implemented, we continue...
if (!Py_IS_TYPE(v, Py_TYPE(w)) &&
PyType_IsSubtype(Py_TYPE(w), Py_TYPE(v)) &&
(f = Py_TYPE(w)->tp_richcompare) != NULL) {
checked_reverse_op = 1;
res = (*f)(w, v, _Py_SwappedOp[op]);
if (res != Py_NotImplemented)
return res;
Py_DECREF(res);
Next we see if we can lookup the __eq__
method from the first type and call it.
As long as the result is not NotImplemented, that is, it is implemented, we return it.
if ((f = Py_TYPE(v)->tp_richcompare) != NULL) {
res = (*f)(v, w, op);
if (res != Py_NotImplemented)
return res;
Py_DECREF(res);
Else if we didn't try the other type's method and it's there, we then try it, and if the comparison is implemented, we return it.
if (!checked_reverse_op && (f = Py_TYPE(w)->tp_richcompare) != NULL) {
res = (*f)(w, v, _Py_SwappedOp[op]);
if (res != Py_NotImplemented)
return res;
Py_DECREF(res);
}
Finally, we get a fallback in case it isn't implemented for either one's type.
The fallback checks for the identity of the object, that is, whether it is the same object at the same place in memory - this is the same check as for self is other
:
/* If neither object implements it, provide a sensible default
for == and !=, but raise an exception for ordering. */
switch (op) {
case Py_EQ:
res = (v == w) ? Py_True : Py_False;
break;
In a comparison, we respect the subclass implementation of comparison first.
Then we attempt the comparison with the first object's implementation, then with the second's if it wasn't called.
Finally we use a test for identity for comparison for equality.
If you want to have text in the edit text and remove it like you say, try:
final EditText text_box = (EditText) findViewById(R.id.input_box);
text_box.setOnFocusChangeListener(new OnFocusChangeListener()
{
@Override
public void onFocusChange(View v, boolean hasFocus)
{
if (hasFocus==true)
{
if (text_box.getText().toString().compareTo("Enter Text")==0)
{
text_box.setText("");
}
}
}
});
Following one liner gives the list you want.
mvv = mvv_count_df.select("mvv").rdd.flatMap(lambda x: x).collect()
Runnable
is an interface defined as so:
interface Runnable {
public void run();
}
To make a class which uses it, just define the class as (public) class MyRunnable implements Runnable {
It can be used without even making a new Thread. It's basically your basic interface with a single method, run, that can be called.
If you make a new Thread with runnable as it's parameter, it will call the run method in a new Thread.
It should also be noted that Threads implement Runnable
, and that is called when the new Thread is made (in the new thread). The default implementation just calls whatever Runnable you handed in the constructor, which is why you can just do new Thread(someRunnable)
without overriding Thread's run
method.

The best way is, using backward slahes and using .bat at the end of activate
C:\Users>your_env_name\Scripts\activate.bat
In order to solve this problem, I recognize two solutions:
The first one goes with AJAX, with which you'll have to load the template from another file and just add everytime you want with .clone()
.
$.get('url/to/template', function(data) {
temp = data
$('.search').keyup(function() {
$('.list-items').html(null);
$.each(items, function(index) {
$(this).append(temp.clone())
});
});
});
Take into account that the event should be added once the ajax has completed to be sure the data is available!
The second one would be to directly add it anywhere in the original html, select it and hide it in jQuery:
temp = $('.list_group_item').hide()
You can after add a new instance of the template with
$('.search').keyup(function() {
$('.list-items').html(null);
$.each(items, function(index) {
$(this).append(temp.clone())
});
});
Same as the previous one, but if you don't want the template to remain there, but just in the javascript, I think you can use (have not tested it!) .detach()
instead of hide.
temp = $('.list_group_item').detach()
.detach()
removes elements from the DOM while keeping the data and events alive (.remove() does not!).
There is no bidirectional map in the Java Standard API. Either you can maintain two maps yourself or use the BidiMap from Apache Collections.

I answered considering Lua5.3
Mac OSX High Sierra 10.13 fixes this somewhat. Just make a virtual APFS partition for your git projects, by default it has no size limit and takes no space.

The first is good unless either Phone1 or (more likely) phone2 can be null. In that case you want to use a Left join instead of an inner join.
It is usually a bad sign when you have a table with two phone number fields. Usually this means your database design is flawed.
One should ask why you would want a public getter method for the password. Hibernate, or any other ORM framework, will do with a private getter method. For checking whether the password is correct, you can use
public boolean checkPassword(String password){
return this.password.equals(anyHashingMethod(password));
}
Just for fun, here's what I'd probably do in a real project, where I'm already using all my favourite libraries (in this case Guava, formerly known as Google Collections).
String text = Files.toString(new File("textfile.txt"), Charsets.UTF_8);
List<Integer> list = Lists.newArrayList();
for (String s : text.split("\\s")) {
list.add(Integer.valueOf(s));
}
Benefit: Not much own code to maintain (contrast with e.g. this). Edit: Although it is worth noting that in this case tschaible's Scanner solution doesn't have any more code!
Drawback: you obviously may not want to add new library dependencies just for this. (Then again, you'd be silly not to make use of Guava in your projects. ;-)
iText has more than one way of doing this. The PdfStamper
class is one option. But I find the easiest method is to create a new PDF document then import individual pages from the existing document into the new PDF.
// Create output PDF
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, outputStream);
document.open();
PdfContentByte cb = writer.getDirectContent();
// Load existing PDF
PdfReader reader = new PdfReader(templateInputStream);
PdfImportedPage page = writer.getImportedPage(reader, 1);
// Copy first page of existing PDF into output PDF
document.newPage();
cb.addTemplate(page, 0, 0);
// Add your new data / text here
// for example...
document.add(new Paragraph("my timestamp"));
document.close();
This will read in a PDF from templateInputStream
and write it out to outputStream
. These might be file streams or memory streams or whatever suits your application.
Not to my knowledge. A foreign key only adds a constraint that the value in the child key also be represented somewhere in the parent column. It's not telling the database that the child key also needs to be indexed, only constrained.
If you need to iterate through the code points of a String
(see this answer) a shorter / more readable way is to use the CharSequence#codePoints
method added in Java 8:
for(int c : string.codePoints().toArray()){
...
}
or using the stream directly instead of a for loop:
string.codePoints().forEach(c -> ...);
There is also CharSequence#chars
if you want a stream of the characters (although it is an IntStream
, since there is no CharStream
).
Maybe you can subclass your button and override your isEnabled variable. The advantage is that you can reuse in multiple places.
override var isEnabled: Bool {
didSet {
if isEnabled {
self.alpha = 1
} else {
self.alpha = 0.2
}
}
}
This is quite easy with jQuery using insertAfter()
or insertBefore()
:
<div class="left">content</div>
<div class="right">sidebar</div>
<script>
$('.right').insertBefore('left');

If you want to to set o condition for mobile devices you can make it like this:
<script>
var $iW = $(window).innerWidth();
if ($iW < 992){
$('.right').insertBefore('.left');
}else{
$('.right').insertAfter('.left');
}

I like the answers by @Artur79 and @mjs so I've been using a combination of both and made it a standard for our projects.
find . -type d -empty -exec touch {}/.gitkeep \;
However, only a handful of our developers work on Mac or Linux. A lot work on Windows and I could not find an equivalent simple one-liner to accomplish the same there. Some were lucky enough to have Cygwin installed for other reasons, but prescribing Cygwin just for this seemed overkill.
Edit for a better solution
So, since most of our developers already have Ant installed, the first thing I thought of was to put together an Ant build file to accomplish this independently of the platform. This can still be found here
However, I later thought It would be better to make this into a small utility command, so I recreated it using Python and published it to the PyPI here. You can install it by simply running:
pip3 install gitkeep2
It will allow you to create and remove .gitkeep
files recursively, and it will also allow you to add messages to them for your peers to understand why those directories are important. This last bit is bonus. I thought it would be nice if the .gitkeep

$ gitkeep --help

even if they're empty.
Read more about why this is necessary at: https://git.wiki.kernel.org/inde

Options:
-r, --recursive Add or remove the .gitkeep files recursively for all
sub-directories in the specified path.
-l, --let-go Remove the .gitkeep files from the specified path.
-e, --empty Create empty .gitkeep files. This will ignore any
message provided
-m, --message TEXT A message to be included in the .gitkeep file, ideally
used to explain why it's important to push the specified
directory to source control even if it's empty.
-v, --verbose Print out everything.
--help Show this message and exit.

I tested all the solutions above and finally decided to empty my Maven repository manually (I actually deleted the .m2

I don't believe that there is a formal limit here, and I'm pretty sure there isn't any hard limit specified in the RFC either, as you found.
I think that some pretty common limitations for subject lines in general (not just e-mail) are:
Obviously, you want to come up with something that is reasonable. If you're writing an e-mail client, you may want to go with something like 256 characters, and obviously test thoroughly against big commercial servers out there to make sure they serve your mail correctly.

I don't believe search and replace will do it for you (doesn't work for me in Excel 2010 Home). Are you sure you want to put "null" in EVERY cell in the sheet? That is millions of cells, in which case there is no way a search and replace would be able to handle it memory-wise (correct me if I am wrong).
In the case I am right and you don't want millions of "null" cells, then here is a macro. It asks you to select the range then put "null" inside every cell that was blank.
Sub FillWithNull()
Dim cell As range
Dim myRange As range
Set myRange = Application.InputBox("Select the range", Type:=8)
Application.ScreenUpdating = False
For Each cell In myRange
If Len(cell) = 0 Then
cell.Value = "Null"
End If
Next
Application.ScreenUpdating = True
End Sub

In XML
use:
android:editable="false"
As an example:
<EditText
android:id="@+id/EditText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:editable="false" />
You are actually getting the correct value out.
The way your x86
(compatible) processor stores data like this, is in Little Endian order, meaning that, the MSB is last in your output.
So, given your output:
10101010
the last two hex values 10
are the Most Significant Byte (2 hex digits = 1 byte = 8 bits
(for (possibly unnecessary) clarification).
So, by reversing the memory storage order of the bytes, your value is actually: 01010101
.
Hope that clears it up!
I also don't like using a function to handle a property which has been resolved again and again in every controller and service. Seem I'm not alone :D
Don't tried to get result with a promise as a variable, of course no way. But I found and use a solution below to access to the result as a property.
Firstly, write result to a property of your service:
app.factory('your_factory',function(){
var theParentIdResult = null;
var factoryReturn = {
theParentId: theParentIdResult,
addSiteParentId : addSiteParentId
};
return factoryReturn;
function addSiteParentId(nodeId) {
var theParentId = 'a';
var parentId = relationsManagerResource.GetParentId(nodeId)
.then(function(response){
factoryReturn.theParentIdResult = response.data;
console.log(theParentId); // #1
});
}
})
Now, we just need to ensure that method addSiteParentId
always be resolved before we accessed to property theParentId
. We can achieve this by using some ways.
Use resolve in router method:
resolve: {
parentId: function (your_factory) {
your_factory.addSiteParentId();
}
}
then in controller and other services used in your router, just call your_factory.theParentId to get your property. Referce here for more information: http://odetocode.com/blogs/scott/archive/2014/05/20/using-resolve-in-angularjs-routes.aspx
Use run
method of app to resolve your service.
app.run(function (your_factory) { your_factory.addSiteParentId(); })
Inject it in the first controller or services of the controller. In the controller we can call all required init services. Then all remain controllers as children of main controller can be accessed to this property normally as you want.
Chose your ways depend on your context depend on scope of your variable and reading frequency of your variable.
If you want to set only one specific class, you might write a TypeScript function returning a boolean to determine when the class should be appended.
TypeScript
function hideThumbnail():boolean{

Daniel LeCheminant's code didn't work for me after converting it from CoffeeScript to JavaScript (js2coffee). It kept bombing out on the _.defer()
line.
I assumed this was something to do with jQuery deferreds, so I changed it to $.Deferred()
and it's working now. I tested it in Internet Explorer 11, Firefox 35, and Chrome 39 with jQuery 2.1.1. The usage is the same as described in Daniel's post.
var TrelloClipboard;
TrelloClipboard = new ((function () {
function _Class() {
this.value = "";
$(document).keydown((function (_this) {
return function (e) {
var _ref, _ref1;
if (!_this.value || !(e.ctrlKey || e.metaKey)) {
return;
}
if ($(e.target).is("input:visible,textarea:visible")) {
return;
}
if (typeof window.getSelection === "function" ? (_ref = window.getSelection()) != null ? _ref.toString() : void 0 : void 0) {
return;
}
if ((_ref1 = document.selection) != null ? _ref1.createRange().text : void 0) {
return;
}
return $.Deferred(function () {
var $clipboardContainer;
$clipboardContainer = $("#clipboard-container");
$clipboardContainer.empty().show();
return $("<textarea id='clipboard'></textarea>").val(_this.value).appendTo($clipboardContainer).focus().select();
});
};
})(this));
$(document).keyup(function (e) {
if ($(e.target).is("#clipboard")) {
return $("#clipboard-container").empty().hide();
}
});
}
_Class.prototype.set = function (value) {
this.value = value;
};
return _Class;
})());
You need to use the ui.item.label (the text) and ui.item.value (the id) properties
$('#selector').autocomplete({
source: url,
select: function (event, ui) {
$("#txtAllowSearch").val(ui.item.label); // display the selected text
$("#txtAllowSearchID").val(ui.item.value); // save selected id to hidden input
}
});
$('#button').click(function() {
alert($("#txtAllowSearchID").val()); // get the id from the hidden input
});
[Edit] You also asked how to create the multi-dimensional array...
You should be able create the array like so:
var $local_source = [[0,"c++"], [1,"java"], [2,"php"], [3,"coldfusion"],
[4,"javascript"], [5,"asp"], [6,"ruby"]];
Read more about how to work with multi-dimensional arrays here: http://www.javascriptkit.com/javatutors/literal-notation2.shtml
I would like to recommend a single header C++ 11 YAML parser mini-yaml.
A quick-start example taken from the above repository.
file.txt
key: foo bar
list:
- hello world
- integer: 123
boolean: true
.cpp
Yaml::Node root;
Yaml::Parse(root, "file.txt");
// Print all scalars.
std::cout << root["key"].As<std::string>() << std::endl;
std::cout << root["list"][0].As<std::string>() << std::endl;
std::cout << root["list"][1]["integer"].As<int>() << std::endl;
std::cout << root["list"][1]["boolean"].As<bool>() << std::endl;
// Iterate second sequence item.
Node & item = root[1];
for(auto it = item.Begin(); it != item.End(); it++)
{
std::cout << (*it).first << ": " << (*it).second.As<string>() << std::endl;
}
Output
foo bar
hello world
123
1
integer: 123
boolean: true
Swift 3 :
tableView.beginUpdates()
tableView.reloadRows(at: [indexPath], with: .automatic)
tableView.endUpdates()
You can use shorthand syntax as of Twig 1.12.0
{{ foo ?: 'no' }} is the same as {{ foo ? foo : 'no' }}
{{ foo ? 'yes' }} is the same as {{ foo ? 'yes' : '' }}
Use List.indexOf()
. This will give you the first match when there are multiple duplicates.
An access violation at anywhere near adress '00000000' indicates a null pointer access. You're using something before it's ever been created, most likely, or after it's been FreeAndNil()'d.
A lot of times this is caused by accessing a component in the wrong place during form creation, or by having your main form try and access something in a datamodule that hasn't been created yet.
MadExcept makes it pretty easy to track these things down, and is free for non-commercial use. (Actually, a commercial use license is pretty inexpensive as well, and well worth the money.)
Just disable IPv6
on the network configuration
Short tags are coming back thanks to Zend Framework pushing the "PHP as a template language" in their default MVC configuration. I don't see what the debate is about, most of the software you will produce during your lifetime will operate on a server you or your company will control. As long as you keep yourself consistent, there shouldn't be any problems.
UPDATE
After doing quite a bit of work with Magento, which uses long form. As a result, I've switched to the long form of:
<?php and <?php echo
over
<? and <?=
Seems like a small amount of work to assure interoperability.
Answers above describe well why and how it is used on twitter and facebook, what I missed is explanation what #
does by default...
On a 'normal' (not a single page application) you can do anchoring with hash
to any element that has id by placing that elements id in url after hash #
Example:
(on Chrome) Click F12 or Rihgt Mouse and Inspect element
then take id="answer-10831233"
and add to url like following
https://stackoverflow.com/questions/3009380/whats-the-shebang-hashbang-in-facebook-and-new-twitter-urls-for#answer-10831233
and you will get a link that jumps to that element on the page
What's the shebang/hashbang (#!) in Facebook and new Twitter URLs for?
By using #
in a way described in the answers above you are introducing conflicting behaviour... although I wouldn't loose sleep over it... since Angular it became somewhat of a standard....
Or you could go the regex route:
String date = "10/07/2010";
String newDate = date.replaceAll("(\\d+)/(\\d+)/(\\d+)", "$3/$2/$1");
System.out.println(newDate);
It works both ways too. Of course this won't actually validate your date and will also work for strings like "21432/32423/52352". You can use "(\\d{2})/(\\d{2})/(\\d{4}"
to be more exact in the number of digits in each group, but it will only work from dd/MM/yyyy to yyyy/MM/dd and not the other way around anymore (and still accepts invalid numbers in there like 45). And if you give it something invalid like "blabla" it will just return the same thing back.
A slightly modified version of @sidanmor 's code. The main point is, not every webpage is purely ASCII, user should be able to handle the decoding manually (even encode into base64)
function httpGet(url) {
return new Promise((resolve, reject) => {
const http = require('http'),
https = require('https');
let client = http;
if (url.toString().indexOf("https") === 0) {
client = https;
}
client.get(url, (resp) => {
let chunks = [];
// A chunk of data has been recieved.
resp.on('data', (chunk) => {
chunks.push(chunk);
});
// The whole response has been received. Print out the result.
resp.on('end', () => {
resolve(Buffer.concat(chunks));
});
}).on("error", (err) => {
reject(err);
});
});
}
(async(url) => {
var buf = await httpGet(url);
console.log(buf.toString('utf-8'));
})('https://httpbin.org/headers');
Pluses:
First: mild, defeatable obfuscation.
Second: if compilation results in a significantly smaller file, you will get faster load times. Nice for the web.
Third: Python can skip the compilation step. Faster at intial load. Nice for the CPU and the web.
Fourth: the more you comment, the smaller the .pyc
or .pyo
file will be in comparison to the source .py
file.
Fifth: an end user with only a .pyc
or .pyo
file in hand is much less likely to present you with a bug they caused by an un-reverted change they forgot to tell you about.
Sixth: if you're aiming at an embedded system, obtaining a smaller size file to embed may represent a significant plus, and the architecture is stable so drawback one, detailed below, does not come into play.
Top level compilation
It is useful to know that you can compile a top level python source file into a .pyc
file this way:
python -m py_compile myscript.py
This removes comments. It leaves docstrings
intact. If you'd like to get rid of the docstrings
as well (you might want to seriously think about why you're doing that) then compile this way instead...
python -OO -m py_compile myscript.py
...and you'll get a .pyo
file instead of a .pyc
file; equally distributable in terms of the code's essential functionality, but smaller by the size of the stripped-out docstrings
(and less easily understood for subsequent employment if it had decent docstrings
in the first place). But see drawback three, below.
Note that python uses the .py
file's date, if it is present, to decide whether it should execute the .py
file as opposed to the .pyc
or .pyo
file --- so edit your .py file, and the .pyc
or .pyo
is obsolete and whatever benefits you gained are lost. You need to recompile it in order to get the .pyc
or .pyo
benefits back again again, such as they may be.
Drawbacks:
First: There's a "magic cookie" in .pyc
and .pyo
files that indicates the system architecture that the python file was compiled in. If you distribute one of these files into an environment of a different type, it will break. If you distribute the .pyc
or .pyo
without the associated .py
to recompile or touch
so it supersedes the .pyc
or .pyo
, the end user can't fix it, either.
Second: If docstrings
are skipped with the use of the -OO
command line option as described above, no one will be able to get at that information, which can make use of the code more difficult (or impossible.)
Third: Python's -OO
option also implements some optimizations as per the -O
command line option; this may result in changes in operation. Known optimizations are:
sys.flags.optimize
= 1assert
statements are skipped__debug__
= FalseFourth: if you had intentionally made your python script executable with something on the order of #!/usr/bin/python
on the first line, this is stripped out in .pyc
and .pyo
files and that functionality is lost.
Fifth: somewhat obvious, but if you compile your code, not only can its use be impacted, but the potential for others to learn from your work is reduced, often severely.
Quick fix: Change how excel converts imported files. Go to 'File', then 'Options', then 'Advanced'. Scroll down and uncheck 'Use system seperators'. Also change 'Decimal separator' to '.' and 'Thousands separator' to ',' . Then simply 're-save' your file in the CSV (Comma delimited) format. The root cause is usually associated with how the csv file is created. Trust that helps. Point is, why use extra code if not necessary? Cross-platform understanding and integration is key in engineering/development.
I wanted to return a string such as "1 day 2 hours 3 minutes" and also take into account if for example days or minuttes are 0 and then not showing them. thanks to John Rasch for his answer which mine is barely an extension of
TimeSpan timeLeft = New Timespan(0, 70, 0);
String.Format("{0}{1}{2}{3}{4}{5}",
Math.Floor(timeLeft.TotalDays) == 0 ? "" :
Math.Floor(timeLeft.TotalDays).ToString() + " ",
Math.Floor(timeLeft.TotalDays) == 0 ? "" : Math.Floor(timeLeft.TotalDays) == 1 ? "day " : "days ",
timeLeft.Hours == 0 ? "" : timeLeft.Hours.ToString() + " ",
timeLeft.Hours == 0 ? "" : timeLeft.Hours == 1 ? "hour " : "hours ",
timeLeft.Minutes == 0 ? "" : timeLeft.Minutes.ToString() + " ",
timeLeft.Minutes == 0 ? "" : timeLeft.Minutes == 1 ? "minute " : "minutes ");
For Bootstrap 3.1 you'll want to remove data and empty the modal-content
rather than the whole dialog (3.0) to avoid the flicker while waiting for remote content to load.
$(document).on("hidden.bs.modal", function (e) {
$(e.target).removeData("bs.modal").find(".modal-content").empty();
});
If you are using non-remote modals then the above code will, of course, remove their content once closed (bad). You may need to add something to those modals (like a .local-modal
class) so they aren't affected. Then modify the above code to:
$(document).on("hidden.bs.modal", ".modal:not(.local-modal)", function (e) {
$(e.target).removeData("bs.modal").find(".modal-content").empty();
});
This command can explicitly set the base URL for your rewrites. If you wish to start in the root of your domain, you would include the following line before your RewriteRule:
RewriteBase /
./manage.py migrate
This solved my issue
Cross apply can be used to replace subquery's where you need a column of the subquery
subquery
select * from person p where
p.companyId in(select c.companyId from company c where c.companyname like '%yyy%')
here i won't be able to select the columns of company table so, using cross apply
select P.*,T.CompanyName
from Person p
cross apply (
select *
from Company C
where p.companyid = c.companyId and c.CompanyName like '%yyy%'
) T
var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?foo=bar';
window.history.pushState({path:newurl},'',newurl);
if it is a RSA key
openssl rsa -pubout -in my_rsa_key.pem
if you need it in a format for openssh , please see Use RSA private key to generate public key?
Note that public key is generated from the private key and ssh uses the identity file (private key file) to generate and send public key to server and un-encrypt the encrypted token from the server via the private key in identity file.
if you want to start application with cmd use this code:
string YourApplicationPath = "C:\\Program Files\\App\\MyApp.exe"
ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.WindowStyle = ProcessWindowStyle.Hidden;
processInfo.FileName = "cmd.exe";
processInfo.WorkingDirectory = Path.GetDirectoryName(YourApplicationPath);
processInfo.Arguments = "/c START " + Path.GetFileName(YourApplicationPath);
Process.Start(processInfo);
You can add a spring.datasource.data
property to application.properties
listing the sql files you want to run. Like this:
spring.datasource.data=classpath:accounts.sql, classpath:books.sql, classpath:reviews.sql
The sql insert statements in each of these files will then be run, allowing you to keep things tidy.
If you put the files in the classpath, for example in src/main/resources
they will be applied. Or replace classpath:
with file:
and use an absolute path to the file
If you want to run DDL type SQL then use:
spring.datasource.schema=classpath:create_account_table.sql
Edit: these solutions are great to get you up and running quickly, however for a more production ready solution it would be worth looking at a framework such as flyway, or liquibase. These frameworks integrate well with spring, and provide a quick, consistent, version-controlled means of initialising schema, and standing-data.
You can have comments in JSONP, but not in pure JSON. I've just spent an hour trying to make my program work with this example from Highcharts: http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=?
If you follow the link, you will see
?(/* AAPL historical OHLC data from the Google Finance API */
[
/* May 2006 */
[1147651200000,67.79],
[1147737600000,64.98],
...
[1368057600000,456.77],
[1368144000000,452.97]
]);
Since I had a similar file in my local folder, there were no issues with the Same-origin policy, so I decided to use pure JSON... and, of course, $.getJSON
was failing silently because of the comments.
Eventually I just sent a manual HTTP request to the address above and realized that the content-type was text/javascript
since, well, JSONP returns pure JavaScript. In this case comments are allowed. But my application returned content-type application/json
, so I had to remove the comments.
This error is caused when async/await
functions are used without the proper Babel plugins. As of March 2020, the following should be all you need to do. (@babel/polyfill
and a lot of the accepted solutions have been deprecated in Babel. Read more in the Babel docs.)
In the command line, type:
npm install --save-dev @babel/plugin-transform-runtime
In your babel.config.js
file, add this plugin @babel/plugin-transform-runtime
. Note: The below example includes the other presets and plugins I have for a small React/Node/Express project I worked on recently:
module.exports = {
presets: ['@babel/preset-react', '@babel/preset-env'],
plugins: ['@babel/plugin-proposal-class-properties',
'@babel/plugin-transform-runtime'],
};
You can also apply the array map method to the Map.entries() iterable:
[...myMap.entries()].map(
([key, value]: [string, number]) => console.log(key, value)
);
Also, as noted in other answers, you may have to enable down level iteration in your tsconfig.json (under compiler options):
"downlevelIteration": true,
If you use visual studio, Team Explorer built-in tool is a very nice tool to resolve git merge conflicts.
Unfortunately, it seems that Git has no such command built in. But you can easily add it yourself with Git aliases and some shell magic.
As pointed out by this answer, you can use git rev-parse --show-toplevel
to show the root of your current Git folder.
If you want to use this regularly, it's probably more convenient to define it as an alias. For this, used git config alias.root '!echo "$(git rev-parse --show-toplevel)"'
. After this, you can use git root
to see the root folder of the repository you're currently in.
If you want to use another subcommand name than root
, simply replace the second part of alias.root
in the above command with whatever you want.
For details on aliases in Git, see also the git config
man page.
If dateutil is missing install it via:
pip install python-dateutil
Or on Ubuntu:
sudo apt-get install python-dateutil
For fine tuning the position of an inline-block
item, use top and left:
position: relative;
top: 5px;
left: 5px;
Thanks CSS-Tricks!
You can use getChanges()
on Eloquent model even after persisting.
Use rename
(aka prename
) which is a Perl script which may be on your system already. Do it in two steps:
find -name "* *" -type d | rename 's/ /_/g' # do the directories first
find -name "* *" -type f | rename 's/ /_/g'
Based on Jürgen's answer and able to handle multiple layers of files and directories in a single bound using the "Revision 1.5 1998/12/18 16:16:31 rmb1" version of /usr/bin/rename
(a Perl script):
find /tmp/ -depth -name "* *" -execdir rename 's/ /_/g' "{}" \;
HI im going to leave this here cz i cant comment due to restrictions but i found AlexFitiskin's answer perfect, but a small correction was needed
document.getElementById('here').innerHTML = data.name;
This needed to be changed to
document.getElementById('here').innerHTML = data.n;
I know that after five years the owner of the post will not find it of any importance but this is for people who might come across in the future .
It is possible to parse dynamic values in a couple of way.
Interpolation with double-curly braces:
ng-style="{'background-image':'url({{myBackgroundUrl}})'}"
String concatenation:
ng-style="{'background-image': 'url(' + myBackgroundUrl + ')'}"
ES6 template literals:
ng-style="{'background-image': `url(${myBackgroundUrl})`}"
Stumbled here looking for the same thing...I then remembered the Iterables
class from the Guava library.
To get the "first" element: Iterables.getFirst( someMap.values(), null );
.
Essentially does the same as Map.values().iterator().next()
, but also allows you to specify a default (in this case null) should there be nothing in the Map.
Iterables.getLast( someMap.values(), null );
returns the last element in the Map.
Iterables.get( someMap.values(), 7, null );
returns the 7th element in the Map if exists, otherwise a default value (in this case null).
Remember though that HashMaps are not ordered...so don't expect Iterables.getFirst
to return the first item you tossed in there...likewise with Iterables.getLast
. Perhaps useful to get a mapped value though.
It may not be worth adding the Guava library for just that, but if you happen to be using some of the other cool utilities within that library...
Looks like you missed this part,
notification.contentIntent = pendingIntent;
Try adding this and it should work.
Add XAttribute
in the constructor of the XElement
, like
new XElement("Conn", new XAttribute("Server", comboBox1.Text));
You can also add multiple attributes or elements via the constructor
new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));
or you can use the Add-Method of the XElement
to add attributes
XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);
You could create a CSS class for this and apply it to your columns. Since the gutter (spacing between columns) is controlled by padding in Bootstrap 3, adjust the padding accordingly:
.col {
padding-right:7px;
padding-left:7px;
}
Demo: http://bootply.com/93473
EDIT If you only want the spacing between columns you can select all cols except first and last like this..
.col:not(:first-child,:last-child) {
padding-right:7px;
padding-left:7px;
}
For Bootstrap 4 see: Remove gutter space for a specific div only
Well, it'd still be convenient (syntactically) if we could declare usual values inside the if's condition. So, here's a trick: you can make the compiler think there is an assignment of Optional.some(T)
to a value like so:
if let i = "abc".firstIndex(of: "a"),
let i_int = .some(i.utf16Offset(in: "abc")),
i_int < 1 {
// Code
}
You can use a dict comprehension for this pretty easily:
a = ['hello','world','1','2']
my_dict = {item : a[index+1] for index, item in enumerate(a) if index % 2 == 0}
This is equivalent to the for loop below:
my_dict = {}
for index, item in enumerate(a):
if index % 2 == 0:
my_dict[item] = a[index+1]
An update on @Scott T.'s answer: the interface between Resource Server and Authorization Server for token validation was standardized in IETF RFC 7662 in October 2015, see: https://tools.ietf.org/html/rfc7662. A sample validation call would look like:
POST /introspect HTTP/1.1
Host: server.example.com
Accept: application/json
Content-Type: application/x-www-form-urlencoded
Authorization: Bearer 23410913-abewfq.123483
token=2YotnFZFEjr1zCsicMWpAA
and a sample response:
HTTP/1.1 200 OK
Content-Type: application/json
{
"active": true,
"client_id": "l238j323ds-23ij4",
"username": "jdoe",
"scope": "read write dolphin",
"sub": "Z5O3upPC88QrAjx00dis",
"aud": "https://protected.example.net/resource",
"iss": "https://server.example.com/",
"exp": 1419356238,
"iat": 1419350238,
"extension_field": "twenty-seven"
}
Of course adoption by vendors and products will have to happen over time.
The accepted answer still threw a Javascript error in IE for me (for Angular 1.2 at least). It is a bug but the workaround is to use ngAttr detailed on https://docs.angularjs.org/guide/interpolation
<input type="text" ng-model="inputText" ng-attr-placeholder="{{somePlaceholder}}" />
Follow the below simple steps you will able to get the result
Step 1- Create one internal function getDetailFromExternal in your back end. step 2- In that function call the external url by using cUrl like below function
function getDetailFromExternal($p1,$p2) {
$url = "http://request url with parameters";
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true
));
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
exit;
}
Step 3- Call that internal function from your front end by using javascript/jquery Ajax.
While instaling (updating) check 'Devel' to 'Install', it will install a lot of MB but helps. I don't have time to check which exacly I (we) need.
Think of "BeforeClass" as a static initializer for your test case - use it for initializing static data - things that do not change across your test cases. You definitely want to be careful about static resources that are not thread safe.
Finally, use the "AfterClass" annotated method to clean up any setup you did in the "BeforeClass" annotated method (unless their self destruction is good enough).
"Before" & "After" are for unit test specific initialization. I typically use these methods to initialize / re-initialize the mocks of my dependencies. Obviously, this initialization is not specific to a unit test, but general to all unit tests.

I know this does not answer this question, but I came here because I had the same error with nodeJS server. I am stuck a long time until I found the solution. My solution just adds slash or /
in end of proxyreserve apache.
my old code is:
ProxyPass / http://192.168.1.1:3001
ProxyPassReverse / http://192.168.1.1:3001
the correct code is:
ProxyPass / http://192.168.1.1:3001/
ProxyPassReverse / http://192.168.1.1:3001/
You can do this by using json and ast modules as follows
>>> import json, ast
>>>
>>> EmployeeList = [u'1001', u'Karick', u'14-12-2020', u'1$']
>>>
>>> result_list = ast.literal_eval(json.dumps(EmployeeList))
>>> result_list
['1001', 'Karick', '14-12-2020', '1$']
The URL is relative to the location of the CSS file, so this should work for you:
url('../../images/image.jpg')
The relative URL goes two folders back, and then to the images
folder - it should work for both cases, as long as the structure is the same.
From https://www.w3.org/TR/CSS1/#url:
Partial URLs are interpreted relative to the source of the style sheet, not relative to the document
You should wrap the .h
file like so:
#ifndef Included_NameModel_H
#define Included_NameModel_H
// Existing code goes here
#endif
The short answer is you can't.
I don't know any PHP syntax, but what I can tell you is that PHP is executed on the server and JavaScript is executed on the client (on the browser).
You're doing a $_GET, which is used to retrieve form values:
The built-in $_GET function is used to collect values in a form with method="get".
In other words, if on your page you had:
<form method="get" action="blah.php">
<input name="test"></input>
</form>
Your $_GET call would retrieve the value in that input field.
So how to retrieve a value from JavaScript?
Well, you could stick the javascript value in a hidden form field...
<script type="text/javascript" charset="utf-8">
var test = "tester";
// find the 'test' input element and set its value to the above variable
document.getElementByID("test").value = test;
</script>
... elsewhere on your page ...
<form method="get" action="blah.php">
<input id="test" name="test" visibility="hidden"></input>
<input type="submit" value="Click me!"></input>
</form>
Then, when the user clicks your submit button, he/she will be issuing a "GET" request to blah.php, sending along the value in 'test'.
It's a time zone change on December 31st in Shanghai.
See this page for details of 1927 in Shanghai. Basically at midnight at the end of 1927, the clocks went back 5 minutes and 52 seconds. So "1927-12-31 23:54:08" actually happened twice, and it looks like Java is parsing it as the later possible instant for that local date/time - hence the difference.
Just another episode in the often weird and wonderful world of time zones.
EDIT: Stop press! History changes...
The original question would no longer demonstrate quite the same behaviour, if rebuilt with version 2013a of TZDB. In 2013a, the result would be 358 seconds, with a transition time of 23:54:03 instead of 23:54:08.
I only noticed this because I'm collecting questions like this in Noda Time, in the form of unit tests... The test has now been changed, but it just goes to show - not even historical data is safe.
EDIT: History has changed again...
In TZDB 2014f, the time of the change has moved to 1900-12-31, and it's now a mere 343 second change (so the time between t
and t+1
is 344 seconds, if you see what I mean).
EDIT: To answer a question around a transition at 1900... it looks like the Java timezone implementation treats all time zones as simply being in their standard time for any instant before the start of 1900 UTC:
import java.util.TimeZone;
public class Test {
public static void main(String[] args) throws Exception {
long startOf1900Utc = -2208988800000L;
for (String id : TimeZone.getAvailableIDs()) {
TimeZone zone = TimeZone.getTimeZone(id);
if (zone.getRawOffset() != zone.getOffset(startOf1900Utc - 1)) {
System.out.println(id);
}
}
}
}
The code above produces no output on my Windows machine. So any time zone which has any offset other than its standard one at the start of 1900 will count that as a transition. TZDB itself has some data going back earlier than that, and doesn't rely on any idea of a "fixed" standard time (which is what getRawOffset
assumes to be a valid concept) so other libraries needn't introduce this artificial transition.
I got the same error recently. I think McX is right it was caused by insufficient memory on RDP server. Here is the solution that works for us.
use sc cmd to get running services on the remote server. Make sure you can use windows explorer to access the remote server \\remote_server.
sc \\<remote_server> query
find out the service you can stop.
sc \\<remote_server> stop <service_name>
After stopping one service, the remote desktop works again.
Almost all Magento Models have a corresponding Collection object that can be used to fetch multiple instances of a Model.
To instantiate a Product collection, do the following
$collection = Mage::getModel('catalog/product')->getCollection();
Products are a Magento EAV style Model, so you'll need to add on any additional attributes that you want to return.
$collection = Mage::getModel('catalog/product')->getCollection();
//fetch name and orig_price into data
$collection->addAttributeToSelect('name');
$collection->addAttributeToSelect('orig_price');
There's multiple syntaxes for setting filters on collections. I always use the verbose one below, but you might want to inspect the Magento source for additional ways the filtering methods can be used.
The following shows how to filter by a range of values (greater than AND less than)
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('name');
$collection->addAttributeToSelect('orig_price');
//filter for products whose orig_price is greater than (gt) 100
$collection->addFieldToFilter(array(
array('attribute'=>'orig_price','gt'=>'100'),
));
//AND filter for products whose orig_price is less than (lt) 130
$collection->addFieldToFilter(array(
array('attribute'=>'orig_price','lt'=>'130'),
));
While this will filter by a name that equals one thing OR another.
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('name');
$collection->addAttributeToSelect('orig_price');
//filter for products who name is equal (eq) to Widget A, or equal (eq) to Widget B
$collection->addFieldToFilter(array(
array('attribute'=>'name','eq'=>'Widget A'),
array('attribute'=>'name','eq'=>'Widget B'),
));
A full list of the supported short conditionals (eq,lt, etc.) can be found in the _getConditionSql
method in lib/Varien/Data/Collection/Db.php
Finally, all Magento collections may be iterated over (the base collection class implements on of the the iterator interfaces). This is how you'll grab your products once filters are set.
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('name');
$collection->addAttributeToSelect('orig_price');
//filter for products who name is equal (eq) to Widget A, or equal (eq) to Widget B
$collection->addFieldToFilter(array(
array('attribute'=>'name','eq'=>'Widget A'),
array('attribute'=>'name','eq'=>'Widget B'),
));
foreach ($collection as $product) {
//var_dump($product);
var_dump($product->getData());
}
There are three obvious ways to communicate with services:
In your case, I'd go with option 3. Make a static reference to the service it self and populate it in onCreate():
void onCreate(Intent i) {
sInstance = this;
}
Make a static function MyService getInstance()
, which returns the static sInstance
.
Then in Activity.onCreate()
you start the service, asynchronously wait until the service is actually started (you could have your service notify your app it's ready by sending an intent to the activity.) and get its instance. When you have the instance, register your service listener object to you service and you are set. NOTE: when editing Views inside the Activity you should modify them in the UI thread, the service will probably run its own Thread, so you need to call Activity.runOnUiThread()
.
The last thing you need to do is to remove the reference to you listener object in Activity.onPause()
, otherwise an instance of your activity context will leak, not good.
NOTE: This method is only useful when your application/Activity/task is the only process that will access your service. If this is not the case you have to use option 1. or 2.
Try calling it directly with class name Book.myInt
Introducer for the return type of a local lambda expression:
std::vector<MyType> seq;
// fill with instances...
std::sort(seq.begin(), seq.end(),
[] (const MyType& a, const MyType& b) -> bool {
return a.Content < b.Content;
});
introducing a trailing return type of a function in combination of the re-invented auto
:
struct MyType {
// declares a member function returning std::string
auto foo(int) -> std::string;
};
Simply type cd
then copy and paste the file path.
Example of changing directory:
For making a CORS request one must add headers to the request along with the same he needs to check of mode_header is enabled in Apache.
For enabling headers in Ubuntu:
sudo a2enmod headers
For php server to accept request from different origin use:
Header set Access-Control-Allow-Origin *
Header set Access-Control-Allow-Methods "GET, POST, PUT, DELETE"
Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"
Erland Sommarskog has maintained the authoritative answer to this question for the last 16 years: Arrays and Lists in SQL Server.
There are at least a dozen ways to pass an array or list to a query; each has their own unique pros and cons.
I really can't recommend enough to read the article to learn about the tradeoffs among all these options.
What if your application does logging some other way – not using the
logging
module?
Now, traceback
could be used here.
import traceback
def log_traceback(ex, ex_traceback=None):
if ex_traceback is None:
ex_traceback = ex.__traceback__
tb_lines = [ line.rstrip('\n') for line in
traceback.format_exception(ex.__class__, ex, ex_traceback)]
exception_logger.log(tb_lines)
Use it in Python 2:
try:
# your function call is here
except Exception as ex:
_, _, ex_traceback = sys.exc_info()
log_traceback(ex, ex_traceback)
Use it in Python 3:
try:
x = get_number()
except Exception as ex:
log_traceback(ex)
