It is sure because the Invoke-WebRequest command has a dependency on the Internet Explorer assemblies and are invoking it to parse the result as per default behaviour. As Matt suggest, you can simply launch IE and make your selection in the settings prompt which is popping up at first launch. And the error you experience will disappear.
But this is only possible if you run your powershell scripts as the same windows user as whom you launched the IE with. The IE settings are stored under your current windows profile. So if you, like me run your task in a scheduler on a server as the SYSTEM user, this will not work.
So here you will have to change your scripts and add the -UseBasicParsing argument, as ijn this example: $WebResponse = Invoke-WebRequest -Uri $url -TimeoutSec 1800 -ErrorAction:Stop -Method:Post -Headers $headers -UseBasicParsing
An easier way if you can't access router.url (for instance if you used skipLocationChange) you can use the following :
constructor(private readonly location: Location) {}
ngOnInit(): void {
console.log(this.location.path());
}
The postgres:9.4
image you've inherited from declares a volume at /var/lib/postgresql/data
. This essentially means you can't copy any files to that path in your image; the changes will be discarded.
You have a few choices:
You could just add your own configuration files as a volume at run-time with docker run -v postgresql.conf:/var/lib/postgresql/data/postgresql.conf ...
. However, I'm not sure exactly how that will interact with the existing volume.
You could copy the file over when the container is started. To do that, copy your file into the build at a location which isn't underneath the volume then call a script from the entrypoint or cmd which will copy the file to correct location and start postgres.
Clone the project behind the Postgres official image and edit the Dockerfile to add your own config file in before the VOLUME is declared (anything added before the VOLUME instruction is automatically copied in at run-time).
Pass all config changes in command option in docker-compose file
like:
services:
postgres:
...
command:
- "postgres"
- "-c"
- "max_connections=1000"
- "-c"
- "shared_buffers=3GB"
- "-c"
...
These files will successfully open sshd and run service so you can ssh in locally. (you are using cyberduck aren't you?)

This is still the highest SO-question on Google when searching for this error, so let's bump it.
When getting this error and not wanting to deep-dive into the NGINX settings immediately, you might want to check your outputs to the debug console. In my case I was outputting loads of text to the FirePHP / Chromelogger console, and since this is all sent as a header, it was causing the overflow.
It might not be needed to change the webserver settings if this error is caused by just sending insane amounts of log messages.
It is not necessary to use another library like newChart or use other people's pull requests to pull this off. All you have to do is define an options object and add the label wherever and however you want it in the tooltip.
var optionsPie = {
tooltipTemplate: "<%= label %> - <%= value %>"
}
If you want the tooltip to be always shown you can make some other edits to the options:
var optionsPie = {
tooltipEvents: [],
showTooltips: true,
onAnimationComplete: function() {
this.showTooltip(this.segments, true);
},
tooltipTemplate: "<%= label %> - <%= value %>"
}
In your data items, you have to add the desired label property and value and that's all.
data = [
{
value: 480000,
color:"#F7464A",
highlight: "#FF5A5E",
label: "Tobacco"
}
];
Now, all you have to do is pass the options object after the data to the new Pie like this: new Chart(ctx).Pie(data,optionsPie)
and you are done.
This probably works best for pies which are not very small in size.
Here is a code to draw a fill elipse, you can use the same method but replacing de xcenter and y center with radius
void drawFilledelipse(GLfloat x, GLfloat y, GLfloat xcenter,GLfloat ycenter) {
int i;
int triangleAmount = 20; //# of triangles used to draw circle
//GLfloat radius = 0.8f; //radius
GLfloat twicePi = 2.0f * PI;
glBegin(GL_TRIANGLE_FAN);
glVertex2f(x, y); // center of circle
for (i = 0; i <= triangleAmount; i++) {
glVertex2f(
x + ((xcenter+1)* cos(i * twicePi / triangleAmount)),
y + ((ycenter-1)* sin(i * twicePi / triangleAmount))
);
}
glEnd();
}
Let's say you have your global scripts file and you don't want to define that URL repeatedly in other files. That's the point where BASE_URL kicks in.
In your global_script.js file, do this
<script>
var BASE_URL = "http://localhost:8000";
</script>
Then you can use that variable anywhere else to call your URL. For example...
<script>
fetch(`{{BASE_URL}}/task-create/`,{
..............
}).then((response) => {
.............
})
</script>
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,

angle = angle,
col = col,
border = border,

ylim = ylim,

warn.unused = warn.unused,
...
)
)
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 {

}
}
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,

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$mids[1:2]) * length(x)
}
lines(xfit, yfit, col = "black", lwd = 2)
}
if (plot == TRUE) {
invisible(h)
} else {
h
}
}
To redirect everything that doesnt exist to index.php
, you can also use the FallBackResource
directive
FallbackResource /index.php
It works same as the ErrorDocument
, when you request a non-existent path or file on the server, the directive silently forwords the request to index.php
.
If you want to redirect everything (including existant files or folders
) to index.php
, you can use something like the following :
RewriteEngine on
RewriteRule ^((?!index\.php).+)$ /index.php [L]
Note the pattern ^((?!index\.php).+)$
matches any uri except index.php
we have excluded the destination path to prevent infinite looping error.
A popular desktop architecture divides a process's virtual memory in several segments:
Text segment: contains the executable code. The instruction pointer takes values in this range.
Data segment: contains global variables (i.e. objects with static linkage). Subdivided in read-only data (such as string constants) and uninitialized data ("BSS").
Stack segment: contains the dynamic memory for the program, i.e. the free store ("heap") and the local stack frames for all the threads. Traditionally the C stack and C heap used to grow into the stack segment from opposite ends, but I believe that practice has been abandoned because it is too unsafe.
A C program typically puts objects with static storage duration into the data segment, dynamically allocated objects on the free store, and automatic objects on the call stack of the thread in which it lives.
On other platforms, such as old x86 real mode or on embedded devices, things can obviously be radically different.
There's no fixed time for retransmission. Simple implementations estimate the RTT (round-trip-time) and if no ACK to send data has been received in 2x that time then they re-send.
They then double the wait-time and re-send once more if again there is no reply. Rinse. Repeat.
More sophisticated systems make better estimates of how long it should take for the ACK as well as guesses about exactly which data has been lost.
The bottom-line is that there is no hard-and-fast rule about exactly when to retransmit. It's up to the implementation. All retransmissions are triggered solely by the sender based on lack of response from the receiver.
TCP never drops data so no, there is no way to indicate a server should forget about some segment.
Using vlines
:
import numpy as np
np.random.seed(5)
x = arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
p = plot(x, y, "o")
vlines(70,100,250)
The basic call signatures are:
vlines(x, ymin, ymax)
hlines(y, xmin, xmax)
Here's a way to do it without regular expressions or explicit loops, although it's stretching the definition of a one liner a bit:
const input = 'abcdefghijlkm';
// Change `3` to the desired split length.
const output = input.split('').reduce((s, c) => {let l = s.length-1; (s[l] && s[l].length < 3) ? s[l] += c : s.push(c); return s;}, []);
console.log(output); // output: [ 'abc', 'def', 'ghi', 'jlk', 'm' ]
It works by splitting the string into an array of individual characters, then using Array.reduce
to iterate over each character. Normally reduce
would return a single value, but in this case the single value happens to be an array, and as we pass over each character we append it to the last item in that array. Once the last item in the array reaches the target length, we append a new array item.
Use ipcs -a
: it gives detailed information of all resources [semaphore, shared-memory etc]
Here is the image of the output:
Calculate the intersection point of the lines laying on your segments (it means basically to solve a linear equation system), then check whether is it between the starting and ending points of your segments.
All the above codes, do not allow to preserve the original image name, which sometimes is required. This will help in saving the images to your local drive, preserving the original image name

Threads share the code and data segments and the heap, but they don't share the stack.
I had the same problem when I'm using spring-context version 4.0.6 and spring-security version 4.1.0.
When changing spring-security version to 4.0.4 (because 4.0.6 of spring-security not available) in my pom and security xml-->schemaLocation, it gets compiled without internet.
So that mean you can also solve this by:
changing spring-security to a older or same version than spring-context.
changing spring-context to a newer or same version than spring-security.
(any way spring-context to be newer or same version to spring-security)

Each row in /proc/$PID/maps
describes a region of contiguous virtual memory in a process or thread. Each row has the following fields:
address perms offset dev inode pathname
08048000-08056000 r-xp 00000000 03:0c 64593 /usr/sbin/gpm
-
will appear instead of the r
/w
/x
. If a region is not shared, it is private, so a p
will appear instead of an s
. If the process attempts to access memory in a way that is not permitted, a segmentation fault is generated. Permissions can be changed using the mprotect
system call.mmap
), this is the offset in the file where the mapping begins. If the memory was not mapped from a file, it's just 0.[heap]
, [stack]
, or [vdso]
. [vdso]
stands for virtual dynamic shared object. It's used by system calls to switch to kernel mode. Here's a good article about it: "What is linux-gate.so.1?"You might notice a lot of anonymous regions. These are usually created by mmap
but are not attached to any file. They are used for a lot of miscellaneous things like shared memory or buffers not allocated on the heap. For instance, I think the pthread library uses anonymous mapped regions as stacks for new threads.

.NET has some handy utility methods for this sort of thing in System.Array:
PS> $a = 'a','b','c'
PS> [array]::IndexOf($a, 'b')
1
PS> [array]::IndexOf($a, 'c')
2
Good points on the above approach in the comments. Besides "just" finding an index of an item in an array, given the context of the problem, this is probably more suitable:
$letters = { 'A', 'B', 'C' }
$letters | % {$i=0} {"Value:$_ Index:$i"; $i++}
Foreach (%) can have a Begin sciptblock that executes once. We set an index variable there and then we can reference it in the process scripblock where it gets incremented before exiting the scriptblock.
x=[1,2,3,4,5]
sum=0
for s in range(0,len(x)):
sum=sum+x[s]
print sum
Well, you need to first get a good book on C and understand the language.
FILE *fp;
fp = fopen("c:\\test.txt", "wb");
if(fp == null)
return;
char x[10]="ABCDEFGHIJ";
fwrite(x, sizeof(x[0]), sizeof(x)/sizeof(x[0]), fp);
fclose(fp);
This XML file does not appear to have any style information associated with it. The document tree is shown below.
You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml
instead of text/html
and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.
In case of JSF/Facelets files which have the default extension of .xhtml
, that can in turn happen if the HTTP request hasn't invoked the FacesServlet
and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml
file extension which is in your Firefox configuration apparently by default interpreted as text/xml
.
You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern>
of the FacesServlet
as registered in webapp's web.xml
, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf
, then you need to open the page by /some.jsf
instead of /some.xhtml
. Alternatively, you can also just change the <url-pattern>
to *.xhtml
. This way you never need to fiddle with virtual URLs.
Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.
This is more of an xpath question, but like this, assuming the context is the parent element:
<xsl:value-of select="name/@attribute1" />

To follow up on the comment by suhendri to Rory McCrossan answer. Here is an Action delegate example:
In child add:
public Action UpdateProgress; // In place of event handler declaration
// declare an Action delegate
.
.
.
private LoadData() {
this.UpdateProgress(); // call to Action delegate - MyMethod in
// parent
}
In parent add:
// The 3 lines in the parent becomes:
ChildClass child = new ChildClass();
child.UpdateProgress = this.MyMethod; // assigns MyMethod to child delegate
To solve this simply add android:windowSoftInputMode="stateVisible|adjustPan
to that activity in android manifest file. for example
<activity
android:name="com.comapny.applicationname.activityname"
android:screenOrientation="portrait"
android:windowSoftInputMode="stateVisible|adjustPan"/>
The lubridate package is amazing for this kind of thing:

My _sqlite3.so is in /usr/lib/python2.5/lib-dynload/_sqlite3.so. Judging from your paths, you should have the file /usr/local/lib/python2.5/lib-dynload/_sqlite3.so.
Try the following:
find /usr/local -name _sqlite3.so
If the file isn't found, something may be wrong with your Python installation. If it is, make sure the path it's installed to is in the Python path. In the Python shell,
import sys
print sys.path
In my case, /usr/lib/python2.5/lib-dynload is in the list, so it's able to find /usr/lib/python2.5/lib-dynload/_sqlite3.so.
Yes, it is possible. The steps are:
First Put the .mdf
and .ldf
file in C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\
folder
Then go to sql software , Right-click “Databases” and click the “Attach” option to open the Attach Databases dialog box
Click the “Add” button to open and Locate Database Files From C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\
folder
Click the "OK" button. SQL Server Management Studio loads the database from the .MDF
file.
You can directly use the EnvironmentPlugin
available in webpack
to have access to any environment variable during the transpilation.
You just have to declare the plugin in your webpack.config.js
file:
var webpack = require('webpack');
module.exports = {
/* ... */
plugins = [
new webpack.EnvironmentPlugin(['NODE_ENV'])
]
};
Note that you must declare explicitly the name of the environment variables you want to use.
One more (in the future) way to conditionally apply style is by conditionally creating scoped style
<style scoped type="text/css" ng-if="...">
</style>
But nowadays only FireFox supports scoped styles.
If we wanted to return the same matrix we would write:
return [[ m[row][col] for col in range(0,width) ] for row in range(0,height) ]
What this does is it iterates over a matrix m by going through each row and returning each element in each column. So the order would be like:
[[1,2,3],
[4,5,6],
[7,8,9]]
Now for question 3, we instead want to go column by column, returning each element in each row. So the order would be like:
[[1,4,7],
[2,5,8],
[3,6,9]]
Therefore just switch the order in which we iterate:
return [[ m[row][col] for row in range(0,height) ] for col in range(0,width) ]
Npm and Bower are both dependency management tools. But the main difference between both is npm is used for installing Node js modules but bower js is used for managing front end components like html, css, js etc.
A fact that makes this more confusing is that npm provides some packages which can be used in front-end development as well, like grunt
and jshint
.
These lines add more meaning
Bower, unlike npm, can have multiple files (e.g. .js, .css, .html, .png, .ttf) which are considered the main file(s). Bower semantically considers these main files, when packaged together, a component.
Edit: Grunt is quite different from Npm and Bower. Grunt is a javascript task runner tool. You can do a lot of things using grunt which you had to do manually otherwise. Highlighting some of the uses of Grunt:
There are grunt plugins for sass compilation, uglifying your javascript, copy files/folders, minifying javascript etc.
Please Note that grunt plugin is also an npm package.
Question-1
When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json
It really depends where does this package belong to. If it is a node module(like grunt,request) then it will go in package.json otherwise into bower json.
Question-2
When should I ever install packages explicitly like that without adding them to the file that manages dependencies
It does not matter whether you are installing packages explicitly or mentioning the dependency in .json file. Suppose you are in the middle of working on a node project and you need another project, say request
, then you have two options:
OR
npm install --save request
--save
options adds the dependency to package.json file as well. If you don't specify --save
option, it will only download the package but the json file will be unaffected.
You can do this either way, there will not be a substantial difference.
In order to get rid of duplicates, you can group by drinks.id
. But that way you'll get only one photo for each drinks.id
(which photo you'll get depends on database internal implementation).
Though it is not documented, in case of MySQL, you'll get the photo with lowest id
(in my experience I've never seen other behavior).
SELECT name, price, photo
FROM drinks, drinks_photos
WHERE drinks.id = drinks_id
GROUP BY drinks.id
In angular only one page is requested from server, that is index.html. And index.html and assets folder are on same directory. while putting image in any component give src value like assets\image.png
. This will work fine because browser will make request to server for that image and webpack will be able serve that image.
Also make sure you put the full image URL not just its relative path:
http://www.example.com/images/favicon.ico
And not:
images/favicon.ico
Check the error details in the Chrome dev toolbar console, this will give you the functions in the call stack, and guide you towards the recursion that's causing the error.
If you don't need to worry so much about older browsers, this is exactly what Sets are designed for.
The Set object lets you store unique values of any type, whether primitive values or object references.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set
const set1 = new Set([1, 2, 3, 4, 5, 1]);
// returns Set(5) {1, 2, 3, 4, 5}
In Swift 3, you can use isNavigationBarHidden Property also to show or hide navigation bar
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
// Hide the navigation bar for current view controller
self.navigationController?.isNavigationBarHidden = true;
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
// Show the navigation bar on other view controllers
self.navigationController?.isNavigationBarHidden = false;
}
function _modulename_getData($field, $table) {
try {
if (empty($field)) {
throw new Exception("The field is undefined.");
}
// rest of code here...
}
catch (Exception $e) {
/*
Here you can either echo the exception message like:
echo $e->getMessage();
Or you can throw the Exception Object $e like:
throw $e;

}
}
Convert Date To String

For Android, change the app name from the Android folder. In the AndroidManifest.xml file, in folder android/app/src/main
, let the android
label refer to the name you prefer, for example,
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
<application
`android:label="myappname"`
// The rest of the code
</application>
</manifest>
While generally correct your solution does not work in all circumstances. Assume a repo dir like this:
# ls **/*
doc/index.html README.txt tmp/dir0/file0 tmp/file1 tmp/file2
doc:
index.html
tmp:
dir0 file1 file2
tmp/dir0:
file0
and a .gitignore like this:
# cat .gitignore
doc
tmp/*
This ignores the doc
directory and all files below tmp
.
Git works as expected, but the given command for listing the ignored files does not.
Lets have a look at what git has to say:
# git ls-files --others --ignored --exclude-standard
tmp/file1
tmp/file2
Notice that doc
is missing from the listing.
You can get it with:
# git ls-files --others --ignored --exclude-standard --directory
doc/
Notice the additional --directory
option.
From my knowledge there is no one command to list all ignored files at once.
But I don't know why tmp/dir0
does not show up at all.
file is not defined in Python3, which you are using apparently. The package you're instaling is not suitable for Python 3, instead, you should install Python 2.7 and try again.
See: http://docs.python.org/release/3.0/whatsnew/3.0.html#builtins
Are you sure branch labs
does not already exist (as in this thread)?
You can't have both a file, and a directory with the same name.
You're trying to get git to do basically this:
% cd .git/refs/heads % ls -l total 0 -rw-rw-r-- 1 jhe jhe 41 2009-11-14 23:51 labs -rw-rw-r-- 1 jhe jhe 41 2009-11-14 23:51 master % mkdir labs mkdir: cannot create directory 'labs': File exists
You're getting the equivalent of the "cannot create directory" error.
When you have a branch with slashes in it, it gets stored as a directory hierarchy under.git/refs/heads
.
Apparently, org.json.simple.JSONArray
implements a raw Iterator. This means that each element is considered to be an Object
. You can try to cast:
for(Object o: arr){
if ( o instanceof JSONObject ) {
parse((JSONObject)o);
}
}
This is how things were done back in Java 1.4 and earlier.
Easy implementation from grokking algorithms
def quicksort(arr):
if len(arr) < 2:
return arr #base case
else:
pivot = arr[0]
less = [i for i in arr[1:] if i <= pivot]
more = [i for i in arr[1:] if i > pivot]
return quicksort(less) + [pivot] + quicksort(more)
In Ubuntu (at least 12.04) it seems sendmail is not installed by default. You will have to install it using the command
sudo apt-get install sendmail-bin
You may also need to configure the proper permissions for it as mentioned above.
colspan
I have a solution based on matching the left edge of the td
to the left edge of the corresponding th
. It should handle arbitrarily complex colspans.
I modified the test case to show that arbitrary colspan
is handled correctly.
$(function($) {
"use strict";
// Only part of the demo, the thFromTd call does the work
$(document).on('mouseover mouseout', 'td', function(event) {
var td = $(event.target).closest('td'),
th = thFromTd(td);
th.parent().find('.highlight').removeClass('highlight');
if (event.type === 'mouseover')
th.addClass('highlight');
});
// Returns jquery object
function thFromTd(td) {
var ofs = td.offset().left,
table = td.closest('table'),
thead = table.children('thead').eq(0),
positions = cacheThPositions(thead),
matches = positions.filter(function(eldata) {
return eldata.left <= ofs;
}),
match = matches[matches.length-1],
matchEl = $(match.el);
return matchEl;
}
// Caches the positions of the headers,
// so we don't do a lot of expensive `.offset()` calls.
function cacheThPositions(thead) {
var data = thead.data('cached-pos'),
allth;
if (data)
return data;
allth = thead.children('tr').children('th');
data = allth.map(function() {
var th = $(this);
return {
el: this,
left: th.offset().left
};
}).toArray();
thead.data('cached-pos', data);
return data;
}
});
.highlight {
background-color: #EEE;
}

Use StringBuilder
class, like so:
StringBuilder meme = new StringBuilder(" ");
// Convert and append your double variable
meme.append(String.valueOf(doubleVariable));
// Convert string builder to string
jTextField9.setText(meme.toString());
You will get you desired output.

You can use below code to find out principal (user email who logged in)
org.opensaml.saml2.core.impl.NameIDImpl principal =
(NameIDImpl) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
String email = principal.getValue();
This code is written on top of SAML.
PDFClown might help, but I would not recommend it for a big or heavy use application.
Let's say you want a number 1-5; you could use the following:
:LOOP
set NUM=%random:~-1,1%
if %NUM% GTR 5 (
goto LOOP )
goto NEXT
Or you could use :~1,1 in place of :~-1,1. The :~-1,1 is not needed, but it greatly reduces the amount of time it takes to hit the right range. Let's say you want a number 1-50, we need to decide between 2 digits and 1 digit. Use:
:LOOP
set RAN1=%random:~-1,1%
if %RAN1% GTR 5 (
goto 1 )
if %RAN1%==5 (
goto LOOP )
goto 2
:1
set NUM=%random:~-1,1%
goto NEXT
:2
set NUM=%random:~-1,2%
goto NEXT
You can add more to this algorithm to decide between large ranges, such as 1-1000.

If you just want the date portion (e.g. 2017-06-27), and you want it to work regardless of time zone and also in Arabic, here is code I wrote:
function isoDate(date) {
if (!date) {
return null
}
date = moment(date).toDate()
// don't call toISOString because it takes the time zone into
// account which we don't want. Also don't call .format() because it
// returns Arabic instead of English
var month = 1 + date.getMonth()
if (month < 10) {
month = '0' + month
}
var day = date.getDate()
if (day < 10) {
day = '0' + day
}
return date.getFullYear() + '-' + month + '-' + day
}
It would be better to add a background item into the style of the app actionbar to consistent with the background color of the customized actionbar:
<item name="android:background">@color/actionbar_bgcolor</item>
After android 6.0, the actionbar even has a margin-right space and cannot be set. Add a right margin adjusting in the activity like this: (the view is the customized actionbar or a right button in it)
int rightMargin = Build.VERSION.SDK_INT>=Build.VERSION_CODES.M ? 0 : 8; // may the same with actionbar leftMargin in px
ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
p.setMargins(p.leftMargin, p.topMargin, rightMargin, p.bottomMargin);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1){
p.setMarginEnd(rightMargin);
}
view.setLayoutParams(p);
The actionbar machenism is just supported after Android 3.0+ app. If we use a toolbar (of support lib v7) instead, we should layout it in each xml of each activity, and take care of the issue of overlapping with system status bar in the Android 5.0 or later device.
It seems possible your class may have been using pre-standard C++. An easy way to tell, is to look at your old programs and check, do you see:
#include <iostream.h>
or
#include <iostream>
The former is pre-standard, and you'll be able to just say cout
as opposed to std::cout
without anything additional. You can get the same behavior in standard C++ by adding
using std::cout;
or
using namespace std;
Just one idea, anyway.
cp -r /home/server/folder/test /home/server/
In one-to-one relation one end must be principal and second end must be dependent. Principal end is the one which will be inserted first and which can exist without the dependent one. Dependent end is the one which must be inserted after the principal because it has foreign key to the principal.
In case of entity framework FK in dependent must also be its PK so in your case you should use:
public class Boo
{
[Key, ForeignKey("Foo")]
public string BooId{get;set;}
public Foo Foo{get;set;}
}
Or fluent mapping
modelBuilder.Entity<Foo>()
.HasOptional(f => f.Boo)
.WithRequired(s => s.Foo);
All of your Laravel files should be in one location. Laravel is exposing its public folder to server. That folder represents some kind of front-controller to whole application. Depending on you server configuration, you have to point your server path to that folder. As I can see there is www site on your picture. www is default root directory on Unix/Linux machines. It is best to take a look inside you server configuration and search for root directory location. As you can see, Laravel has already file called .htaccess, with some ready Apache configuration.
From System Preferences, turn on the "Show Keyboard & Character Viewer in menu bar" setting.
Then, the "Character Viewer" menu will pop up a tool that will let you search for any unicode character (by name) and insert it ? you're all set.

First the good news. This code does what you want (please note the "line numbers")
Sub a()
10: On Error GoTo ErrorHandler
20: DivisionByZero = 1 / 0
30: Exit Sub
ErrorHandler:
41: If Err.Number <> 0 Then
42: Msg = "Error # " & Str(Err.Number) & " was generated by " _
& Err.Source & Chr(13) & "Error Line: " & Erl & Chr(13) & Err.Description
43: MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext
44: End If
50: Resume Next
60: End Sub
When it runs, the expected MsgBox is shown:
And now the bad news:
Line numbers are a residue of old versions of Basic. The programming environment usually took charge of inserting and updating them. In VBA and other "modern" versions, this functionality is lost.
However, Here there are several alternatives for "automatically" add line numbers, saving you the tedious task of typing them ... but all of them seem more or less cumbersome ... or commercial.
HTH!
There is a limit to the total size of all columns inlined into the index definition. That said though, I have never had to create index that wide. To me, the bigger advantage is the fact that you can cover more queries with one index that has included columns as they don't have to be defined in any particular order. Think about is as an index within the index. One example would be the StoreID (where StoreID is low selectivity meaning that each store is associated with a lot of customers) and then customer demographics data (LastName, FirstName, DOB): If you just inline those columns in this order (StoreID, LastName, FirstName, DOB), you can only efficiently search for customers for which you know StoreID and LastName.
On the other hand, defining the index on StoreID and including LastName, FirstName, DOB columns would let you in essence do two seeks- index predicate on StoreID and then seek predicate on any of the included columns. This would let you cover all possible search permutationsas as long as it starts with StoreID.
Set objHTTP = CreateObject("MSXML2.ServerXMLHTTP")
URL = "http://www.somedomain.com"
objHTTP.Open "POST", URL, False
objHTTP.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
objHTTP.send("")
Alternatively, for greater control over the HTTP request you can use WinHttp.WinHttpRequest.5.1
in place of MSXML2.ServerXMLHTTP
.
You can (should) use CROSS JOIN
. Following query will be equivalent to yours:
SELECT
table1.columnA
, table2.columnA
FROM table1
CROSS JOIN table2
WHERE table1.columnA = 'Some value'
or you can even use INNER JOIN with some always true conditon:
FROM table1
INNER JOIN table2 ON 1=1
Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):
1) Commits on remote branch since when local branch was created:
git diff HEAD...origin/master
2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:
git diff origin/master...HEAD
3) See the answer by dbyrne.
2018 Solution, still other answers are valid but you dont need to use any dependency:
First you have to create a new migration:
php artisan make:migration change_appointment_time_column_type
Then in that migration file up()
, try:
Schema::table('appointments', function ($table) {
$table->string('time')->change();
});
If you donot change the size default will be varchar(191)
but If you want to change size of the field:
Schema::table('appointments', function ($table) {
$table->string('time', 40)->change();
});
Then migrate the file by:
php artisan migrate
Next matches all greater or equal to 11100
:
^([1-9][1-9][1-9]\d{2}\d*|[1-9][2-9]\d{3}\d*|[2-9]\d{4}\d*|\d{6}\d*)$
^([5-9]\d{1}\d*|\d{3}\d*)$
See pattern and modify to any number. Also it would be great to find some recursive forward/backward operators for large numbers.
For people who needs to validate years earlier than year 1900, following should do the trick. Actually this is same as the above answer given by [@OammieR][1]
BUT with years including 1800 - 1899.
/^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((18|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((18|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((19|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$/
Hope this helps someone who needs to validate years earlier than 1900, such as 01/01/1855
, etc.
Thanks @OammieR
for the initial idea.
I realise this is quite an old thread but it's one of the first results when searching for this problem.
There's a simple solution to this which afaik has always been available... This is also the "recommended" way of doing the same task in VBA.
var lastCell = mySheet.getRange(mySheet.getLastRow(),1).getNextDataCell(
SpreadsheetApp.Direction.UP
);
This will return the last full cell in the column you specify in getRange(row,column), remember to add 1 to this if you want to use the first empty row.
I felt like replying as well, explaining the same thing as the others a bit differently. I am sure you know most of this, but it might help someone else.
<a href="#" class="view">
The
href="#"
part is a commonly used way to make sure the link doesn't lead anywhere on it's own. the #-attribute is used to create a link to some other section in the same document. For example clicking a link of this kind:
<a href="#news">Go to news</a>
will take you to wherever you have the
<a name="news"></a>
code. So if you specify # without any name like in your case, the link leads nowhere.
The
class="view"
part gives it an identifier that CSS or javascript can use. Inside the CSS-files (if you have any) you will find specific styling procedures on all the elements tagged with the "view"-class.
To find out where the URL is specified I would look in the javascript code. It is either written directly in the same document or included from another file.
Search your source code for something like:
<script type="text/javascript"> bla bla bla </script>
or
<script> bla bla bla </script>
and then search for any reference to your "view"-class. An included javascript file can look something like this:
<script type="text/javascript" src="include/javascript.js"></script>
In that case, open javascript.js under the "include" folder and search in that file. Most commonly the includes are placed between <head>
and </head>
or close to the </body>
-tag.
A faster way to find the link is to search for the actual link it goes to. For example, if you are directed to http://www.google.com/search?q=html when you click it, search for "google.com" or something in all the files you have in your web project, just remember the included files.
In many text editors you can open all the files at once, and then search in them all for something.
_.toArray(obj);
Outputs as:
[

If you prefer to know which files the workaround is related to here's what I found. Simple change the .classpath file to
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="src" path="gen"/>
<classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>
<classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.LIBRARIES"/>
<classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.DEPENDENCIES"/>
<classpathentry kind="output" path="bin/classes"/>
</classpath>
Replace the .classpath file in all library projects and in main android project. The .classpath file is in the root folder of the eclipse project. Of cause don't forget to add your own classpath entries, should you have any (so compare with your current version of .classpath).
I believe this is the same result as going through the eclipse menus as componavt-user explained above (Eclipse / Configure Build Path / Order and Export).
From my limited experience, this happens for two main reasons:
The simple solution here is to use an error handler ending with Resume Next
If your lookup_value

In addition to what awd mentioned about getting the person responsible for the server to reconfigure (an impractical solution for local development) I use a change-origin chrome plugin like this:

Try returning the dataset from your stored procedure to your datatable in C# or VB.Net. Then the large amount of data in your datatable can be copied to your destination table using a Bulk Copy. I have used BulkCopy for loading large datatables with thousands of rows, into Sql tables with great success in terms of performance.
You may want to experiment with BulkCopy in your C# or VB.Net code.

If you can't edit the CSS file you can still add another one, or a style tag in the head tag.
If you are not using any primary key, then execute following queries at one single stroke. By replacing values:
# table_name - Your Table Name
# column_name_of_duplicates - Name of column where duplicate entries are found
create table table_name_temp like table_name;
insert into table_name_temp select distinct(column_name_of_duplicates),value,type from table_name group by column_name_of_duplicates;
delete from table_name;
insert into table_name select * from table_name_temp;
drop table table_name_temp
It is always advisable to take backup of database before you play with it.
If you're only interested in international numbers and you'd like to be able to show the flag of the country that matches the country code in the input, I wrote a small library for that:
https://github.com/tfcporciuncula/phonemoji
Here's how it looks:
This counts the rows of the inner query:
select count(*) from (
select count(SID)
from Test
where Date = '2012-12-10'
group by SID
) t
However, in this case the effect of that is the same as this:
select count(distinct SID) from Test where Date = '2012-12-10'
I had the same problem;
textStatus = 'error'
errorThrown = (empty)
xhr.status = 0
That fits my problem exactly. It turns out that when I was loading the HTML-page from my own computer this problem existed, but when I loaded the HTML-page from my webserver it went alright. Then I tried to upload it to another domain, and again the same error occoured. Seems to be a cross-domain problem. (in my case at least)
I have tried calling it this way also:
var request = $.ajax({
url: "http://crossdomain.url.net/somefile.php", dataType: "text",
crossDomain: true,
xhrFields: {
withCredentials: true
}
});
but without success.
This post solved it for me: jQuery AJAX cross domain
Take a look at Doug Neiner's Downloadify which is a Flash based JavaScript interface to do this.
Downloadify is a tiny JavaScript + Flash library that enables the generation and saving of files on the fly, in the browser, without server interaction.

Here's one of the examples demoing direct and indirect sending of commands, with states as IObserver(of signal), thus responders to a signal source, IObservable(of signal):

using System.Collections.Generic;
using System.Linq;
using System.Text;

using Machines;
public static class WatchingTvSampleAdvanced
{
// Enum type for the transition triggers (instead of System.String) :
public enum TvOperation { Plug, SwitchOn, SwitchOff, Unplug, Dispose }
// The state machine class type is also used as the type for its possible states constants :
public class Television : NamedState<Television, TvOperation, DateTime>
{
// Declare all the possible states constants :
public static readonly Television Unplugged = new Television("(Unplugged TV)");
public static readonly Television Off = new Television("(TV Off)");
public static readonly Television On = new Television("(TV On)");
public static readonly Television Disposed = new Television("(Disposed TV)");
// For convenience, enter the default start state when the parameterless constructor executes :
public Television() : this(Television.Unplugged) { }
// To create a state machine instance, with a given start state :
private Television(Television value) : this(null, value) { }
// To create a possible state constant :

Note : this example is rather artificial and mostly meant to demo a number of orthogonal features. There should seldomly be a real need to implement the state value domain itself by a full blown class, using the CRTP ( see : http://en.wikipedia.org/wiki/Curiously_recurring_template_pattern ) like this.
Here's for a certainly simpler and likely much more common implementation use case (using a simple enum type as the states value domain), for the same state machine, and with the same test case :

public object With { get; set; }
}
// State<Status> is a shortcut for / derived from State<Status, string>,
// which in turn is a shortcut for / derived from State<Status, string, object> :
public class Device : State<Status>
{
// Executed before and after every state transition :
protected override void OnChange(ExecutionStep step, Status value, string info, object args)
{
if (step == ExecutionStep.EnterState)
{
// 'value' is the state value that we have transitioned FROM :
Console.WriteLine("\t{0} -- {1} -> {2}", value, info, this);
}
}
public override string ToString() { return Value.ToString(); }
}
// Since 'Device' has no state graph of its own, define one for derived 'Television' :

public class Television : Device { }
public static void Run()

Console.Clear();
// Create a television state machine instance, and return it, set in some start state :

// Trigger some state transitions with no arguments
// ('args' is ignored by this state machine's OnChange(...), anyway) :

tv.

MoveNext("Switch On").
MoveNext("Switch Off").
MoveNext("Switch On").
MoveNext("Switch Off").
MoveNext("Unplug").
MoveNext("Dispose") // MoveNext(...) returns null iff tv.IsFinal == true

'HTH
It's unbelievable how much misleading information you can read in articles above...
And even in microsoft msdn documentation IsBadPtr is claimed to be banned. Oh well - I prefer working application rather than crashing. Even if term working might be working incorrectly (as long as end-user can continue with application).
By googling I haven't found any useful example for windows - found a solution for 32-bit apps,
but I need also to support 64-bit apps, so this solution did not work for me.
But I've harvested wine's source codes, and managed to cook similar kind of code which would work for 64-bit apps as well - attaching code here:
#include <typeinfo.h>
typedef void (*v_table_ptr)();
typedef struct _cpp_object
{
v_table_ptr* vtable;
} cpp_object;
#ifndef _WIN64
typedef struct _rtti_object_locator
{
unsigned int signature;
int base_class_offset;
unsigned int flags;
const type_info *type_descriptor;
//const rtti_object_hierarchy *type_hierarchy;
} rtti_object_locator;
#else
typedef struct
{
unsigned int signature;
int base_class_offset;
unsigned int flags;
unsigned int type_descriptor;
unsigned int type_hierarchy;
unsigned int object_locator;
} rtti_object_locator;
#endif
/* Get type info from an object (internal) */
static const rtti_object_locator* RTTI_GetObjectLocator(void* inptr)
{
cpp_object* cppobj = (cpp_object*) inptr;
const rtti_object_locator* obj_locator = 0;
if (!IsBadReadPtr(cppobj, sizeof(void*)) &&
!IsBadReadPtr(cppobj->vtable - 1, sizeof(void*)) &&
!IsBadReadPtr((void*)cppobj->vtable[-1], sizeof(rtti_object_locator)))
{
obj_locator = (rtti_object_locator*) cppobj->vtable[-1];
}
return obj_locator;
}
And following code can detect whether pointer is valid or not, you need probably to add some NULL checking:
CTest* t = new CTest();
//t = (CTest*) 0;
//t = (CTest*) 0x12345678;
const rtti_object_locator* ptr = RTTI_GetObjectLocator(t);
#ifdef _WIN64
char *base = ptr->signature == 0 ? (char*)RtlPcToFileHeader((void*)ptr, (void**)&base) : (char*)ptr - ptr->object_locator;
const type_info *td = (const type_info*)(base + ptr->type_descriptor);
#else
const type_info *td = ptr->type_descriptor;
#endif
const char* n =td->name();
This gets class name from pointer - I think it should be enough for your needs.
One thing which I'm still afraid is performance of pointer checking - in code snipet above there is already 3-4 API calls being made - might be overkill for time critical applications.
It would be good if someone could measure overhead of pointer checking compared for example to C#/managed c++ calls.
I have the following in a types.ts
file for html input, select, and textarea:
export type InputChangeEventHandler = React.ChangeEventHandler<HTMLInputElement>
export type TextareaChangeEventHandler = React.ChangeEventHandler<HTMLTextAreaElement>
export type SelectChangeEventHandler = React.ChangeEventHandler<HTMLSelectElement>
Then import them:
import { InputChangeEventHandler } from '../types'
Then use them:
const updateName: InputChangeEventHandler = (event) => {
// Do something with `event.currentTarget.value`
}
const updateBio: TextareaChangeEventHandler = (event) => {
// Do something with `event.currentTarget.value`
}
const updateSize: SelectChangeEventHandler = (event) => {
// Do something with `event.currentTarget.value`
}
Then apply the functions on your markup (replacing ...
with other necessary props):
<input onChange={updateName} ... />
<textarea onChange={updateName} ... />
<select onChange={updateSize} ... >
// ...
</select>
My issue was that end users would start typing in a textbox and receive autocomplete (ACP) suggestions and update the calling control if a suggestion was selected as the ACP is designed by default. However, I also needed to update multiple other controls (textboxes, DropDowns, etc...) with data specific to the end user's selection. I have been trying to figure out an elegant solution to the issue and I feel the one I developed is worth sharing and hopefully will save you at least some time.

When the project was originally created, the click-once signing certificate was added on the signing tab of the project's properties. This signs the click-once manifest when you build it. Between then and now, that certificate is no longer available. Either this wasn't the machine you originally built it on or it got cleaned up somehow. You need to re-add that certificate to your machine or chose another certificate.
Size of pointer and int is 2 bytes in Turbo C compiler on windows 32 bit machine.
So size of pointer is compiler specific. But generally most of the compilers are implemented to support 4 byte pointer variable in 32 bit and 8 byte pointer variable in 64 bit machine).
So size of pointer is not same in all machines.
As per ECMAScript 6, you can use the findIndex
function.
array[array.findIndex(x => x.name == 'string 1')]
In C++ the requirements imposed on default arguments with regard to their location in parameter list are as follows:
Default argument for a given parameter has to be specified no more than once. Specifying it more than once (even with the same default value) is illegal.
Parameters with default arguments have to form a contiguous group at the end of the parameter list.
Now, keeping that in mind, in C++ you are allowed to "grow" the set of parameters that have default arguments from one declaration of the function to the next, as long as the above requirements are continuously satisfied.
For example, you can declare a function with no default arguments
void foo(int a, int b);
In order to call that function after such declaration you'll have to specify both arguments explicitly.
Later (further down) in the same translation unit, you can re-declare it again, but this time with one default argument
void foo(int a, int b = 5);
and from this point on you can call it with just one explicit argument.
Further down you can re-declare it yet again adding one more default argument
void foo(int a = 1, int b);
and from this point on you can call it with no explicit arguments.
The full example might look as follows
void foo(int a, int b);
int main()
{
foo(2, 3);
void foo(int a, int b = 5); // redeclare
foo(8); // OK, calls `foo(8, 5)`
void foo(int a = 1, int b); // redeclare again
foo(); // OK, calls `foo(1, 5)`
}
void foo(int a, int b)
{
// ...
}
As for the code in your question, both variants are perfectly valid, but they mean different things. The first variant declares a default argument for the second parameter right away. The second variant initially declares your function with no default arguments and then adds one for the second parameter.
The net effect of both of your declarations (i.e. the way it is seen by the code that follows the second declaration) is exactly the same: the function has default argument for its second parameter. However, if you manage to squeeze some code between the first and the second declarations, these two variants will behave differently. In the second variant the function has no default arguments between the declarations, so you'll have to specify both arguments explicitly.

This works on Tomcat and ofcourse Jboss. However in the end I decided to use the solution Spring provides (as mentioned by rozky) which is far more portable.
You'll need to serialize your object into some kind of string representation. One possible string representation is JSON, and one of the easiest ways to serialize to/from JSON in android, if you ask me, is through Google GSON.
In that case you just put the string return value from (new Gson()).toJson(myObject);
and retrieve the string value and use fromJson
to turn it back into your object.
If your object isn't very complex, however, it might not be worth the overhead, and you could consider passing the separate values of the object instead.
Also, if your table has no ID column, or sorting by id doesn't return you the last row, you can always use sqlite schema native 'rowid' field.
SELECT column
FROM table
WHERE rowid = (SELECT MAX(rowid) FROM table);
convert_dtypes
The (self) accepted answer doesn't take into consideration the possibility of NaNs in object columns.
df = pd.DataFrame({
'a': [1, 2, np.nan],
'b': [True, False, np.nan]}, dtype=object)
df
a b
0 1 True
1 2 False
2 NaN NaN
df['a'].astype(str).astype(int) # raises ValueError
This chokes because the NaN is converted to a string "nan", and further attempts to coerce to integer will fail. To avoid this issue, we can soft-convert columns to their corresponding nullable type using convert_dtypes
:
df.convert_dtypes()
a b
0 1 True
1 2 False
2 <NA> <NA>
df.convert_dtypes().dtypes
a Int64
b boolean
dtype: object
If your data has junk text mixed in with your ints, you can use pd.to_numeric
as an initial step:
s = pd.Series(['1', '2', '...'])
s.convert_dtypes() # converts to string, which is not what we want
0 1
1 2
2 ...
dtype: string
# coerces non-numeric junk to NaNs
pd.to_numeric(s, errors='coerce')
0 1.0
1 2.0
2 NaN
dtype: float64
# one final `convert_dtypes` call to convert to nullable int
pd.to_numeric(s, errors='coerce').convert_dtypes()
0 1
1 2
2 <NA>
dtype: Int64
The answer by Nick Mitchinson is for Bootstrap version 2.
If you are using Bootstrap version 3, then forms have changed a bit. For bootstrap 3, use the following instead:
<div class="form-horizontal">
<div class="form-group">
<div class="col-md-6">
<textarea class="form-control" rows="3" placeholder="What's up?" required></textarea>
</div>
</div>
</div>
Where, col-md-6 will target medium sized devices. You can add col-xs-6 etc to target smaller devices.
Set your own content container class with 1000px width property and then use container-fluid boostrap class instead of container.
Works but might not be the best solution.
Abstract: You need to set the owner of the directory to the user that PHP uses (web server user).
Step 1: Determine PHP User
Create a PHP file containing the following:
<?php echo `whoami`; ?>
Upload it to your web server. The output should be similar to the following:
www-data
Therefore, the PHP user is www-data
.
Step 2: Determine Owner of Directory
Next, check the details of the web directory via the command line:
ls -dl /var/www/example.com/public_html/example-folder
The result should be similar to the following:
drwxrwxr-x 2 exampleuser1 exampleuser2 4096 Mar 29 16:34 example-folder
Therefore, the owner of the directory is exampleuser1
.
Step 3: Change Directory Owner to PHP User
Afterwards, change the owner of the web directory to the PHP user:
sudo chown -R www-data /var/www/example.com/public_html/example-folder
Verify that the owner of the web directory has been changed:
ls -dl /var/www/example.com/public_html/example-folder
The result should be similar to the following:
drwxrwxr-x 2 www-data exampleuser2 4096 Mar 29 16:34 example-folder
Therefore, the owner of example-folder
has successfully been changed to the PHP user: www-data
.
Done! PHP should now be able to write to the directory.

clause.
IF @value
has a value (NOT NULL
) it will compare MyColumn
to
@value
.
Reference: COALESCE (Transact-SQL).
You can use the android.text.StaticLayout
class for this. That's what TextView
uses internally.
There's more than one way to skin this problem so here's my solution:
dict.Select(i => $"{i.Key}: {i.Value}").ToList().ForEach(Console.WriteLine);
this error messages means that CABundle is not given by (-CAfile ...) OR the CABundle file is not closed by a self-signed root certificate.
Don't worry. The connection to server will work even you get theis message from openssl s_client ... (assumed you dont take other mistake too)
If you come to this thread because you're using the node postgres / pg module, there is a better solution than setting NODE_TLS_REJECT_UNAUTHORIZED
or rejectUnauthorized
, which will lead to insecure connections.
Instead, configure the "ssl" option to match the parameters for tls.connect:
{
ca: fs.readFileSync('/path/to/server-ca.pem').toString(),
cert: fs.readFileSync('/path/to/client-cert.pem').toString(),
key: fs.readFileSync('/path/to/client-key.pem').toString(),
servername: 'my-server-name' // e.g. my-project-id/my-sql-instance-id for Google SQL
}
I've written a module to help with parsing these options from environment variables like PGSSLROOTCERT
, PGSSLCERT
, and PGSSLKEY
:
You would be best off using collections.defaultdict
(added in Python 2.5). This allows you to specify the default object type of a missing key (such as a list
).
So instead of creating a key if it doesn't exist first and then appending to the value of the key, you cut out the middle-man and just directly append to non-existing keys to get the desired result.
A quick example using your data:
>>> from collections import defaultdict
>>> data = [(2010, 2), (2009, 4), (1989, 8), (2009, 7)]
>>> d = defaultdict(list)
>>> d
defaultdict(<type 'list'>, {})
>>> for year, month in data:
... d[year].append(month)
...
>>> d
defaultdict(<type 'list'>, {2009: [4, 7], 2010: [2], 1989: [8]})
This way you don't have to worry about whether you've seen a digit associated with a year or not. You just append and forget, knowing that a missing key will always be a list. If a key already exists, then it will just be appended to.
You can pass you session variables from your php script to JQUERY using JSON such as
JS:
jQuery("#rowed2").jqGrid({
url:'yourphp.php?q=3',
datatype: "json",
colNames:['Actions'],
colModel:[{
name:'Actions',
index:'Actions',
width:155,
sortable:false
}],
rowNum:30,
rowList:[50,100,150,200,300,400,500,600],
pager: '#prowed2',
sortname: 'id',
height: 660,
viewrecords: true,
sortorder: 'desc',
gridview:true,
editurl: 'yourphp.php',
caption: 'Caption',
gridComplete: function() {
var ids = jQuery("#rowed2").jqGrid('getDataIDs');
for (var i = 0; i < ids.length; i++) {
var cl = ids[i];
be = "<input style='height:22px;width:50px;' `enter code here` type='button' value='Edit' onclick=\"jQuery('#rowed2').editRow('"+cl+"');\" />";
se = "<input style='height:22px;width:50px;' type='button' value='Save' onclick=\"jQuery('#rowed2').saveRow('"+cl+"');\" />";
ce = "<input style='height:22px;width:50px;' type='button' value='Cancel' onclick=\"jQuery('#rowed2').restoreRow('"+cl+"');\" />";
jQuery("#rowed2").jqGrid('setRowData', ids[i], {Actions:be+se+ce});
}
}
});
PHP
// start your session
session_start();
// get session from database or create you own
$session_username = $_SESSION['John'];
$session_email = $_SESSION['[email protected]'];
$response = new stdClass();
$response->session_username = $session_username;
$response->session_email = $session_email;
$i = 0;
while ($row = mysqli_fetch_array($result)) {
$response->rows[$i]['id'] = $row['ID'];
$response->rows[$i]['cell'] = array("", $row['rowvariable1'], $row['rowvariable2']);
$i++;
}
echo json_encode($response);
// this response (which contains your Session variables) is sent back to your JQUERY
If you can add in a '.' (dot) character at the end of each line, this seems to prevent Outlook ruining text formatting.
docker ps -a
This command saves modified container state into a new image user/test_image
docker commit $CONTAINER_ID user/test_image
docker run -ti --entrypoint=sh user/test_image

Steps above just start a stopped container with the same filesystem state. That is great for a quick investigation. But environment variables, network configuration, attached volumes and other staff is not inherited, you should specify all these arguments explicitly.
Steps to start a stopped container have been borrowed from here: (last comment) https://github.com/docker/docker/issues/18078
This is an old thread, but I stumbled across it when trying to solve a similar problem.
For me, I got this particular error relating to the php_wincache.dll
. I was in the process of updating PHP from 5.5.38 to 5.6.31 on a Windows server. For some reason, not all of the DLL files updated with the newest versions. Most did, but some didn't.
So, if you get an error similar to this, make sure all the extensions are in place and updated.
I prefer the Execute via SQL*Plus option. It's in the little down-arrow menu under the "Execute as script" toolbar button.
There's a really cool function called document.elementFromPoint
which does what it sounds like.
What we need is to find the x and y coords of the mouse and then call it using those values:
var x = event.clientX, y = event.clientY,
elementMouseIsOver = document.elementFromPoint(x, y);
Did you check the small Mousetrap library?
Mousetrap is a simple library for handling keyboard shortcuts in JavaScript.
declare @T table(Roles xml)
insert into @T values
('<root>
<role>Alpha</role>
<role>Beta</role>
<role>Gamma</role>
</root>')
declare @Role varchar(10)
set @Role = 'Beta'
select Roles
from @T
where Roles.exist('/root/role/text()[. = sql:variable("@Role")]') = 1
If you want the query to work as where col like '%Beta%'
you can use contains
declare @T table(Roles xml)
insert into @T values
('<root>
<role>Alpha</role>
<role>Beta</role>
<role>Gamma</role>
</root>')
declare @Role varchar(10)
set @Role = 'et'
select Roles
from @T
where Roles.exist('/root/role/text()[contains(., sql:variable("@Role"))]') = 1
In my case the issue was I had installed an app with the package name let's say com.example.package using android studio on my device. I created another app with the same package name and was trying to install it on my device. That is what was causing the problem. So just check on your device whether another app with the same package name already exists or not.
As you can't import a .txt file, I would suggest to read words this way.
list_ = open("world.txt").read().split()
For those strictly looking for a solution that works for input or textarea, this is the simplest solution I've came across. Only a few lines of CSS and one line of JS.
The JavaScript sets a data-* attribute on the element equal to the value of the input. The input is set within a CSS grid, where that grid is a pseudo-element that uses that data-* attribute as its content. That content is what stretches the grid to the appropriate size based on the input value.
As the answer is marked correct then it's a Windows Dos prompt script and this will work too:
find "string" status.txt >nul && call "my batch file.bat"
Setters and getters are used to replace directly accessing member variables from external classes. if you use a setter and getter in accessing a property, you can include initialization, error checking, complex transformations, etc. Some examples:
private String x;
public void setX(String newX) {
if (newX == null) {
x = "";
} else {
x = newX;
}
}
public String getX() {
if (x == null) {
return "";
} else {
return x;
}
}
The only reason that the linter complains about using setState({..})
in componentDidMount
and componentDidUpdate
is that when the component render the setState immediately causes the component to re-render.
But the most important thing to note: using it inside these component's lifecycles is not an anti-pattern in React.
Please take a look at this issue. you will understand more about this topic. Thanks for reading my answer.
I guess there is no white list in whatsapp, as I found a solution that worked for me. Do as follows. insert 3 meta tags:
<meta property="og:image" content="http://yourimage_with_complete_URL.png"/>
<meta property="og:title" content="Your Title"/>
<meta property="og:description" content="Your description."/>
Your image must be in .png format and 600x600px dimension and must be named 'logo-yoursite.png' (once it worked for me JUST LIKE THAT)
Dont forget to insert the link to whatsapp in your website:
<a href='whatsapp://send?text=Text to send withe message: http://www.yoursite.com'>whatsApp</a>
Do this and you'll be well done!
I'd create a cte and do an inner join. It's not efficient but it's convenient
with table as (
SELECT DATE, STATUS, TITLE, ROW_NUMBER()
OVER (PARTITION BY DATE, STATUS, TITLE ORDER BY QUANTITY ASC) AS Row_Num
FROM TABLE)
select *
from table t
join select(
max(Row_Num) as Row_Num
,DATE
,STATUS
,TITLE
from table
group by date, status, title) t2
on t2.Row_Num = t.Row_Num and t2
and t2.date = t.date
and t2.title = t.title
If you using windows, you can fix it via install SVN Tool. If you using Linux/MacOS, you can fix it via install subversion. After that, just select using svn command. Your problems is resolve.
int val = '1' & 15;
The binary of the ASCII charecters 0-9 is:
0 - 00110000
1 - 00110001
2 - 00110010
3 - 00110011
4 - 00110100
5 - 00110101
6 - 00110110
7 - 00110111
8 - 00111000
9 - 00111001
and if you take in each one of them the first 4 LSB(using bitwise AND with 8'b00001111 that equels to 15) you get the actual number (0000 = 0,0001=1,0010=2,... )
As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.
Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash
is incorrect and should have been callbackOnLocationHash
(note the mis-spelling of "Location").
This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.
Example:
interface TextOptions {
alignment?: string;
color?: string;
padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'
There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes
Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v
or v as T
) do not check for extra properties, so you can use them in place of a type annotation:
interface Options {
x?: string;
y?: number;
}
// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;
Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking
Before
interface Model {
name: string;
}
function createModel(x: Model) { ... }
// Error
createModel({name: 'hello', length: 100});
After
interface Model {
name: string;
[others: string]: any;
}
function createModel(x: Model) { ... }
// OK
createModel({name: 'hello', length: 100});
interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }
let x: Animal;
if(...) {
x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
x = { move: 'catwalk', meow: 'mrar' };
} else {
x = { move: 'gallop', neigh: 'wilbur' };
}
Two good solutions come to mind here
Specify a closed set for x
// Removes all errors
let x: Dog|Cat|Horse;
or Type assert each thing
// For each initialization
x = { move: 'doggy paddle', woof: 'bark' } as Dog;
A clean solution to the "data model" problem using intersection types:
interface DataModelOptions {
name?: string;
id?: number;
}
interface UserProperties {
[key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
/* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
/* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

To look at it a bit differently: setInterval insures that a code is run at every given interval (i.e. 1000ms, or how much you specify) while setTimeout sets the time that it 'waits until' it runs the code. And since it takes extra milliseconds to run the code, it adds up to 1000ms and thus, setTimeout runs again at inexact times (over 1000ms).
For example, timers/countdowns are not done with setTimeout, they are done with setInterval, to ensure it does not delay and the code runs at the exact given interval.
I was struggling with a similar problem yesterday. I already had a "working" solution using jQuery UI's draggable together with jQuery Touch Punch, which are mentioned in other answers. However, using this method was causing weird bugs in some Android devices for me, and therefore I decided to write a small jQuery plugin that can make HTML elements draggable by using touch events instead of using a method that emulates fake mouse events.
The result of this is jQuery Draggable Touch which is a simple jQuery plugin for making elements draggable, that has touch devices as it's main target by using touch events (like touchstart, touchmove, touchend, etc.). It still has a fallback that uses mouse events if the browser/device doesn't support touch events.

A couple other options:
Use the comma operator to create an array:
$cars = ,"bmw"
$cars.GetType().FullName
# Outputs: System.Object[]
Use array subexpression syntax:
$cars = @("bmw")
$cars.GetType().FullName
# Outputs: System.Object[]
If you don't want an object array you can downcast to the type you want e.g. a string array.
[string[]] $cars = ,"bmw"
[string[]] $cars = @("bmw")
Thanks, finally got an solution to not put utf8::encode all over code. To synthesize and complete for other cases, like write and read files in utf8 and also works with LoadFile of an YAML file in utf8
use utf8;
use open ':encoding(utf8)';
binmode(STDOUT, ":utf8");
open(FH, ">test.txt");
print FH "something éá";
use YAML qw(LoadFile Dump);
my $PUBS = LoadFile("cache.yaml");
my $f = "2917";
my $ref = $PUBS->{$f};
print "$f \"".$ref->{name}."\" ". $ref->{primary_uri}." ";
where cache.yaml is:
---
2917:
id: 2917
name: Semanário
primary_uri: 2917.xml
Use the std::vector
class from the standard library.
The WHERE
clause is always conceptually applied (the execution plan can do what it wants, obviously) prior to the GROUP BY
. It must come before the GROUP BY
in the query, and acts as a filter before things are SUM
med, which is how most of the answers here work.
You should also be aware of the optional HAVING
clause which must come after the GROUP BY
. This can be used to filter on the resulting properties of groups after GROUP
ing - for instance HAVING SUM(Amount) > 0
An option is to use the OkHttp client, from Square.
Add the library dependency
In the build.gradle, include this line:
compile 'com.squareup.okhttp:okhttp:x.x.x'
Where x.x.x
is the desired library version.
Set the client
For example, if you want to set a timeout of 60 seconds, do this way:
final OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);
ps: If your minSdkVersion is greater than 8, you can use TimeUnit.MINUTES
. So, you can simply use:
okHttpClient.setReadTimeout(1, TimeUnit.MINUTES);
okHttpClient.setConnectTimeout(1, TimeUnit.MINUTES);
For more details about the units, see TimeUnit.

One scenario where your git repo will get seriously bigger with each commit is one where you are committing binary files that you generate regularly. Their storage won't be as efficient than text file.
Another is one where you have a huge number of files within one repo (which is a limit of git) instead of several subrepos (managed as submodules).
In this article on git space, AlBlue mentions:
Note that Git (and Hg, and other DVCSs) do suffer from a problem where (large) binaries are checked in, then deleted, as they'll still show up in the repository and take up space, even if they're not current.
If you have large binaries stored in your git repo, you may consider:
git filter-branch
(warning: this will rewrite the history, which is bad if you have already pushed your repo and if other have pulled from it)As I mentioned in "What are the file limits in Git (number and size)?", the more recent (2015, 5 years after this answer) Git LFS from GitHub is a way to manage those large files (by storing them outside the Git repository).
I wanted to detect for the presence of .NET version 4.5.2 installed on my system, and I found no better solution than ASoft .NET Version Detector.

CTRL+SHIFT+ENTER, ARRAY FORMULA EXCEL 2016 MAC. So I arrive late into the game, but maybe someone else will. This almost drove me nuts. No matter what I searched for in Google I came up empty. Whatever I tried, no solution seemed to be in sight. Switched to Excel 2016 quite some time ago and today I needed to do some array formulas. Also sitting on a MacBook Pro 15 Touch Bar 2016. Not that it really matters, but still, since the solution was published on Youtube in 2013. The reason why, for me anyway, nothing worked, is in the Mac OS, the control key by default, for me anyway, is set to manage Mission control, which, at least for me, disabled the control button in Excel. In order to enable the key to actually control functions in Excel, you need to go to System preferences > Mission Control, and disable shortcuts for Mission control. So, let's see how long this solution will last. Probably be back to square one after the coffee break. Have a good one!
Try to use the func below to add colorbar:
def add_colorbar(mappable):
from mpl_toolkits.axes_grid1 import make_axes_locatable
import matplotlib.pyplot as plt
last_axes = plt.gca()
ax = mappable.axes
fig = ax.figure
divider = make_axes_locatable(ax)
cax = divider.append_axes("right", size="5%", pad=0.05)
cbar = fig.colorbar(mappable, cax=cax)
plt.sca(last_axes)
return cbar
Then you codes need to be modified as:
fig , ( (ax1,ax2) , (ax3,ax4)) = plt.subplots(2, 2,sharex = True,sharey=True)
z1_plot = ax1.scatter(x,y,c = z1,vmin=0.0,vmax=0.4)
add_colorbar(z1_plot)
str.c_str()
gives you a const char *
, which is an LPCSTR
(Long Pointer to Constant STRing) -- means that it's a pointer to a 0
terminated string of characters. W
means wide string (composed of wchar_t
instead of char
).
newString = yourString.Substring(0, yourString.length -1);
Another hacked solution, though might be a little cleaner by implementing a Proxy button:
HTML:
<input id="fileInput" type="file">
<md-button class="md-raised" ng-click="upload()">
<label>AwesomeButtonName</label>
</md-button>
JS:
app.controller('NiceCtrl', function ( $scope) {
$scope.upload = function () {
angular.element(document.querySelector('#fileInput')).click();
};
};
A bit unrelated answer to OP but for people like me with a somewhat similar problem.
Use Case: Ubuntu (C, Clion, Auto-completion):
I had the same error,
CMake Error: Cannot determine link language for target "hello".
set_target_properties(hello PROPERTIES LINKER_LANGUAGE C)
help fixes that problem but the headers aren't included to the project and the autocompletion wont work.
This is what i had
cmake_minimum_required(VERSION 3.5)
project(hello)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES ./)
add_executable(hello ${SOURCE_FILES})
set_target_properties(hello PROPERTIES LINKER_LANGUAGE C)
No errors but not what i needed, i realized including a single file as source will get me autocompletion as well as it will set the linker to C
.
cmake_minimum_required(VERSION 3.5)
project(hello)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES ./1_helloworld.c)
add_executable(hello ${SOURCE_FILES})
Why are you specifying myFile
there?
Git revert reverts the commit(s) that you specify.
git revert HEAD~2
reverts the HEAD~2
commit
git revert HEAD~2 myfile
reverts HEAD~2
AND myFile
I take myFile
is a file that you want to revert? In that case use
git checkout HEAD~2 -- myFile
This is a followup to the font-forge
section of @Kurt Pfeifle's answer, specific to Red Hat (and possibly other Linux distros).
Once you have your TTF file, you can install it on your system by
/usr/share/fonts
(as root)fc-cache -f /usr/share/fonts/
(as root)If you can find the DB files... "cp DBFiles backup/"
Almost for sure not advisable in most cases, but it's simple as all getup.
You need #include<string>
to use string
AND #include<iostream>
to use cin
and cout
. (I didn't get it when I read the answers). Here's some code which works:
#include<string>
#include<iostream>
using namespace std;
int main()
{
string name;
cin >> name;
string message("hi");
cout << name << message;
return 0;
}
Using the is
or as
operators is the correct way if you know the interface type at compile time and have an instance of the type you are testing. Something that no one else seems to have mentioned is Type.IsAssignableFrom
:
if( typeof(IMyInterface).IsAssignableFrom(someOtherType) )
{
}
I think this is much neater than looking through the array returned by GetInterfaces
and has the advantage of working for classes as well.
Setting the CurrentCell
and then calling BeginEdit(true)
works well for me.
The following code shows an eventHandler for the KeyDown
event that sets a cell to be editable.
My example only implements one of the required key press overrides but in theory the others should work the same. (and I'm always setting the [0][0] cell to be editable but any other cell should work)
private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Tab && dataGridView1.CurrentCell.ColumnIndex == 1)
{
e.Handled = true;
DataGridViewCell cell = dataGridView1.Rows[0].Cells[0];
dataGridView1.CurrentCell = cell;
dataGridView1.BeginEdit(true);
}
}
If you haven't found it previously, the DataGridView FAQ is a great resource, written by the program manager for the DataGridView control, which covers most of what you could want to do with the control.
There is a good guide of how to do this here.

I created 2 servers, listening on same port 8081, running from same code, while learning
1st server creation shud have worked 2nd server creation failed with EADDRINUSE
node.js callback delays might be reason behind neither worked, or 2nd server creation had exception, and program exited, so 1st server is also closed
2 server issue hint, I got from: How to fix Error: listen EADDRINUSE while using nodejs?
you should not use Integer[]
array inside the list as arraylist itself is a kind of array. Just leave the []
and it should work
Aside from limiting the columns selected to reduce bandwidth and memory:
DataTable t;
t.Columns.Remove("columnName");
t.Columns.RemoveAt(columnIndex);
Quick Fix for Development
For development, you could just disable the cache in Chrome Dev Tools (Disabling Chrome cache for website development). The cache disabling happens only if the dev tools dialog is open, so you need not worry about toggling this option every time you do regular browsing.
Note: Using 'urlArgs' is the proper solution in production so that users get the latest code. But it makes debugging difficult because chrome invalidates breakpoints with every refresh (because its a 'new' file being served each time).

Below code allows you to retain some html tags while stripping all others
function strip_tags(input, allowed) {
allowed = (((allowed || '') + '')
.toLowerCase()
.match(/<[a-z][a-z0-9]*>/g) || [])
.join(''); // making sure the allowed arg is a string containing only tags in lowercase (<a><b><c>)
var tags = /<\/?([a-z][a-z0-9]*)\b[^>]*>/gi,
commentsAndPhpTags = /<!--[\s\S]*?-->|<\?(?:php)?[\s\S]*?\?>/gi;
return input.replace(commentsAndPhpTags, '')
.replace(tags, function($0, $1) {
return allowed.indexOf('<' + $1.toLowerCase() + '>') > -1 ? $0 : '';
});
}
list1.RemoveAll(l => list2.Contains(l));
You can use Oracle's SQL Developer tool to do that (My Oracle DB version is 11). While creating a table choose Advanced option and click on the Identity Column tab at the bottom and from there choose Column Sequence. This will generate a AUTO_INCREMENT column (Corresponding Trigger and Squence) for you.
Linear Search
looks through items until it finds the searched value.
Efficiency: O(n)
Example Python Code:
test_list = [1, 3, 9, 11, 15, 19, 29]
test_val1 = 25
test_val2 = 15
def linear_search(input_array, search_value):
index = 0
while (index < len(input_array)) and (input_array[index] < search_value):
index += 1
if index >= len(input_array) or input_array[index] != search_value:
return -1
return index
print linear_search(test_list, test_val1)
print linear_search(test_list, test_val2)
Binary Search
finds the middle element of the array. Checks that middle value is greater or lower than the search value. If it is smaller, it gets the left side of the array and finds the middle element of that part. If it is greater, gets the right part of the array. It loops the operation until it finds the searched value. Or if there is no value in the array finishes the search.
Efficiency: O(logn)
Example Python Code:
test_list = [1, 3, 9, 11, 15, 19, 29]
test_val1 = 25
test_val2 = 15
def binary_search(input_array, value):
low = 0
high = len(input_array) - 1
while low <= high:
mid = (low + high) / 2
if input_array[mid] == value:
return mid
elif input_array[mid] < value:
low = mid + 1
else:
high = mid - 1
return -1
print binary_search(test_list, test_val1)
print binary_search(test_list, test_val2)

If you aren't dynamically loading scripts or marking them as defer
or async
, then scripts are loaded in the order encountered in the page. It doesn't matter whether it's an external script or an inline script - they are executed in the order they are encountered in the page. Inline scripts that come after external scripts are held until all external scripts that came before them have loaded and run.
Async scripts (regardless of how they are specified as async) load and run in an unpredictable order. The browser loads them in parallel and it is free to run them in whatever order it wants.
There is no predictable order among multiple async things. If one needed a predictable order, then it would have to be coded in by registering for load notifications from the async scripts and manually sequencing javascript calls when the appropriate things are loaded.
When a script tag is inserted dynamically, how the execution order behaves will depend upon the browser. You can see how Firefox behaves in this reference article. In a nutshell, the newer versions of Firefox default a dynamically added script tag to async unless the script tag has been set otherwise.
A script tag with async
may be run as soon as it is loaded. In fact, the browser may pause the parser from whatever else it was doing and run that script. So, it really can run at almost any time. If the script was cached, it might run almost immediately. If the script takes awhile to load, it might run after the parser is done. The one thing to remember with async
is that it can run anytime and that time is not predictable.
A script tag with defer
waits until the entire parser is done and then runs all scripts marked with defer
in the order they were encountered. This allows you to mark several scripts that depend upon one another as defer
. They will all get postponed until after the document parser is done, but they will execute in the order they were encountered preserving their dependencies. I think of defer
like the scripts are dropped into a queue that will be processed after the parser is done. Technically, the browser may be downloading the scripts in the background at any time, but they won't execute or block the parser until after the parser is done parsing the page and parsing and running any inline scripts that are not marked defer
or async
.
Here's a quote from that article:
script-inserted scripts execute asynchronously in IE and WebKit, but synchronously in Opera and pre-4.0 Firefox.
The relevant part of the HTML5 spec (for newer compliant browsers) is here. There is a lot written in there about async behavior. Obviously, this spec doesn't apply to older browsers (or mal-conforming browsers) whose behavior you would probably have to test to determine.
A quote from the HTML5 spec:
Then, the first of the following options that describes the situation must be followed:
If the element has a src attribute, and the element has a defer attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element must be added to the end of the list of scripts that will execute when the document has finished parsing associated with the Document of the parser that created the element.
The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.
If the element has a src attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)
The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.
If the element does not have a src attribute, and the element has been flagged as "parser-inserted", and the Document of the HTML parser or XML parser that created the script element has a style sheet that is blocking scripts The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)
Set the element's "ready to be parser-executed" flag. The parser will handle executing the script.
If the element has a src attribute, does not have an async attribute, and does not have the "force-async" flag set The element must be added to the end of the list of scripts that will execute in order as soon as possible associated with the Document of the script element at the time the prepare a script algorithm started.
The task that the networking task source places on the task queue once the fetching algorithm has completed must run the following steps:
If the element is not now the first element in the list of scripts that will execute in order as soon as possible to which it was added above, then mark the element as ready but abort these steps without executing the script yet.
Execution: Execute the script block corresponding to the first script element in this list of scripts that will execute in order as soon as possible.
Remove the first element from this list of scripts that will execute in order as soon as possible.
If this list of scripts that will execute in order as soon as possible is still not empty and the first entry has already been marked as ready, then jump back to the step labeled execution.
If the element has a src attribute The element must be added to the set of scripts that will execute as soon as possible of the Document of the script element at the time the prepare a script algorithm started.
The task that the networking task source places on the task queue once the fetching algorithm has completed must execute the script block and then remove the element from the set of scripts that will execute as soon as possible.
Otherwise The user agent must immediately execute the script block, even if other scripts are already executing.
What about Javascript module scripts, type="module"
?
Javascript now has support for module loading with syntax like this:
<script type="module">
import {addTextToBody} from './utils.mjs';
addTextToBody('Modules are pretty cool.');
</script>
Or, with src
attribute:
<script type="module" src="http://somedomain.com/somescript.mjs">
</script>
All scripts with type="module"
are automatically given the defer
attribute. This downloads them in parallel (if not inline) with other loading of the page and then runs them in order, but after the parser is done.
Module scripts can also be given the async
attribute which will run inline module scripts as soon as possible, not waiting until the parser is done and not waiting to run the async
script in any particular order relative to other scripts.
There's a pretty useful timeline chart that shows fetch and execution of different combinations of scripts, including module scripts here in this article: Javascript Module Loading.
Change ng-disabled="!contractTypeValid"

For formula cells, excel stores two things. One is the Formula itself, the other is the "cached" value (the last value that the forumla was evaluated as)
If you want to get the last cached value (which may no longer be correct, but as long as Excel saved the file and you haven't changed it it should be), you'll want something like:
for(Cell cell : row) {
if(cell.getCellType() == Cell.CELL_TYPE_FORMULA) {
System.out.println("Formula is " + cell.getCellFormula());
switch(cell.getCachedFormulaResultType()) {
case Cell.CELL_TYPE_NUMERIC:
System.out.println("Last evaluated as: " + cell.getNumericCellValue());
break;
case Cell.CELL_TYPE_STRING:
System.out.println("Last evaluated as \"" + cell.getRichStringCellValue() + "\"");
break;
}
}
}
You're getting the error message
ValueError: setting an array element with a sequence.
because you're trying to set an array element with a sequence. I'm not trying to be cute, there -- the error message is trying to tell you exactly what the problem is. Don't think of it as a cryptic error, it's simply a phrase. What line is giving the problem?
kOUT[i]=func(TempLake[i],Z)
This line tries to set the ith
element of kOUT
to whatever func(TempLAke[i], Z)
returns. Looking at the i=0
case:
In [39]: kOUT[0]
Out[39]: 0.0
In [40]: func(TempLake[0], Z)
Out[40]: array([ 0., 0., 0., 0.])
You're trying to load a 4-element array into kOUT[0]
which only has a float. Hence, you're trying to set an array element (the left hand side, kOUT[i]
) with a sequence (the right hand side, func(TempLake[i], Z)
).
Probably func
isn't doing what you want, but I'm not sure what you really wanted it to do (and don't forget you can usually use vectorized operations like A*B rather than looping in numpy.) That should explain the problem, anyway.
If you're using Maven, just follow the maven-war-plugin
documentation about "How do I create a JAR containing the classes in my webapp?": add <attachClasses>true</attachClasses>
to the <configuration>
of the plugin:
<project>
...
<artifactId>mywebapp</artifactId>
<version>1.0-SNAPSHOT</version>
...
<build>
<plugins>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.6</version>
<configuration>
<attachClasses>true</attachClasses>
</configuration>
</plugin>
</plugins>
</build>
...
</project>
The you will have 2 products in the target/
folder:
project.war
itselfproject-classes.jar
which contains all the compiled classes in a jarThen you will be able to execute a main class using classic method: java -cp target/project-classes.jar 'com.mycompany.MainClass' param1 param2
If you are using curl versions curl-7.19.7-46.el6.x86_64 or older. Please provide an option as -k1 (small K1).
This issue is due to ArrayList variable not being instantiated. Need to declare "recordings" variable like following, that should solve the issue;
ArrayList<String> recordings = new ArrayList<String>();
this calls default constructor and assigns empty string to the recordings variable so that it is not null anymore.
You can simply map nginx's root folder to the location of your website:
nano /etc/nginx/sites-enabled/default
inside the default file, look for the root in the server tag and change your website's default folder, e.g. my websites are at /var/www
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /var/www; <-- Here!
...
When I was evaluating nginx, apache2 and lighttpd, I mapped all of them to my website sitting at /var/www. I found this the best way to evaluate efficiently.
Then you can start/stop the server of your choice and see which performs best.
e.g.
service apache2 stop
service nginx start
Btw, nginx actually is very fast!
I see that no good desciption for using numpy.nditer() is here. So, I am gonna go with one. According to NumPy v1.21 dev0 manual, The iterator object nditer, introduced in NumPy 1.6, provides many flexible ways to visit all the elements of one or more arrays in a systematic fashion.
I have to calculate mean_squared_error and I have already calculate y_predicted and I have y_actual from the boston dataset, available with sklearn.
def cal_mse(y_actual, y_predicted):
""" this function will return mean squared error
args:
y_actual (ndarray): np array containing target variable
y_predicted (ndarray): np array containing predictions from DecisionTreeRegressor
returns:
mse (integer)
"""
sq_error = 0
for i in np.nditer(np.arange(y_pred.shape[0])):
sq_error += (y_actual[i] - y_predicted[i])**2
mse = 1/y_actual.shape[0] * sq_error
return mse

If your script is named with the .ps1

This is true for me anyway on Windows 10 with PowerShell version 5.1 anyway, and I don't think I've done anything to make it possible.

I have solved above problem Applying below steps
And after you made thses changes, do following changes in your web.config
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v12.0;AttachDbFilename=|DataDirectory|\aspnet-Real-Time-Commenting-20170927122714.mdf;Initial Catalog=aspnet-Real-Time-Commenting-20170927122714;Integrated Security=true" providerName="System.Data.SqlClient" />
I wanted something similar - a function that parses a string that can be passed as a parameter or piped.
I came up with a solution as below (works as #!/bin/sh
and as #!/bin/bash
)
#!/bin/sh
set -eu
my_func() {
local content=""
# if the first param is an empty string or is not set
if [ -z ${1+x} ]; then
# read content from a pipe if passed or from a user input if not passed
while read line; do content="${content}$line"; done < /dev/stdin
# first param was set (it may be an empty string)
else
content="$1"
fi
echo "Content: '$content'";
}
printf "0. $(my_func "")\n"
printf "1. $(my_func "one")\n"
printf "2. $(echo "two" | my_func)\n"
printf "3. $(my_func)\n"
printf "End\n"
Outputs:
0. Content: ''
1. Content: 'one'
2. Content: 'two'
typed text
3. Content: 'typed text'
End
For the last case (3.) you need to type, hit enter and CTRL+D to end the input.
Please follow the below code. I am sure your problem will be solved.
if (imm != null){
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
}
It should be (-###
is similar to -v
):
echo | gcc -### -E - -march=native
To show the "real" native flags for gcc.
You can make them appear more "clearly" with a command:
gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )//g'
and you can get rid of flags with -mno-* with:
gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )|( -mno-[^\ ]+)//g'
It may be useful to notice that very good answers given above may not be enough. It is because of one more tick is required here:
In Certificates Panel, right click some certificate -> All tasks -> Manage private key -> Add IIS_IUSRS User with full control
In my case, I didnt't need to install my certificate with "Allow private key to be exported" option checked, like said in other answers.
Have you considered reading a book on PHP security? Highly recommended.
I have had much success with the following method for non SSL certified sites.
Dis-allow multiple sessions under the same account, making sure you aren't checking this solely by IP address. Rather check by token generated upon login which is stored with the users session in the database, as well as IP address, HTTP_USER_AGENT and so forth
Using Relation based hyperlinks Generates a link ( eg. http://example.com/secure.php?token=2349df98sdf98a9asdf8fas98df8 ) The link is appended with a x-BYTE ( preferred size ) random salted MD5 string, upon page redirection the randomly generated token corresponds to a requested page.
Short Life-span session authentication cookie. as posted above, a cookie containing a secure string, which is one of the direct references to the sessions validity is a good idea. Make it expire every x Minutes, reissuing that token, and re-syncing the session with the new Data. If any mis-matches in the data, either log the user out, or having them re-authenticate their session.
I am in no means an expert on the subject, I'v had a bit of experience in this particular topic, hope some of this helps anyone out there.
I was able to get it to work in IE and FF with jQuery's:
$(window).bind('beforeunload', function(){
});
instead of: unload, onunload, or onbeforeunload
//if(data="undefined"){
This is an assignment statement, not a comparison. Also, "undefined"
is a string, it's a property. Checking it is like this: if (data === undefined)
(no quotes, otherwise it's a string value)
If it's not defined, you may be returning an empty string. You could try checking for a falsy
value like if (!data)
as well
Got it.
sort(mMyClassVector.begin(), mMyClassVector.end(),

I assumed it'd figure out that the > operator returned a bool (per documentation). But apparently it is not so.
use ONLY
function init() {
about = document.getElementById("about");
about.style.color = 'blue';
}
.innerHTML()
sets or gets the HTML syntax describing the element's descendants., All you need is an object here.
The best form is this

Something like this - for each line read into string variable a
:
>>> a = "123,456"
>>> b = a.split(",")
>>> b
['123', '456']
>>> c = [int(e) for e in b]
>>> c
[123, 456]
>>> x, y = c
>>> x
123
>>> y
456
Now you can do what is necessary with x
and y
as assigned, which are integers.

and
operator and or

This means that $a = true and false;

In most cases you will probably want to use &&

As Chris suggests, you can do it like this:
public string GetXMLAsString(XmlDocument myxml)
{
return myxml.OuterXml;
}
Or like this:
public string GetXMLAsString(XmlDocument myxml)
{
StringWriter sw = new StringWriter();
XmlTextWriter tx = new XmlTextWriter(sw);
myxml.WriteTo(tx);
string str = sw.ToString();//
return str;
}
and if you really want to create a new XmlDocument
then do this
XmlDocument newxmlDoc= myxml

I know this question is old, but there is a way to solve this until C++20 finally brings this feature from C to C++. What you can do to solve this is use preprocessor macros with static_asserts to check your initialization is valid. (I know macros are generally bad, but here I don't see another way.) See example code below:
#define INVALID_STRUCT_ERROR "Instantiation of struct failed: Type, order or number of attributes is wrong."
#define CREATE_STRUCT_1(type, identifier, m_1, p_1) \
{ p_1 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\
#define CREATE_STRUCT_2(type, identifier, m_1, p_1, m_2, p_2) \
{ p_1, p_2 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_2) >= sizeof(identifier.m_1), INVALID_STRUCT_ERROR);\
#define CREATE_STRUCT_3(type, identifier, m_1, p_1, m_2, p_2, m_3, p_3) \
{ p_1, p_2, p_3 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_2) >= sizeof(identifier.m_1), INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_3) >= (offsetof(type, m_2) + sizeof(identifier.m_2)), INVALID_STRUCT_ERROR);\
#define CREATE_STRUCT_4(type, identifier, m_1, p_1, m_2, p_2, m_3, p_3, m_4, p_4) \
{ p_1, p_2, p_3, p_4 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_2) >= sizeof(identifier.m_1), INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_3) >= (offsetof(type, m_2) + sizeof(identifier.m_2)), INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_4) >= (offsetof(type, m_3) + sizeof(identifier.m_3)), INVALID_STRUCT_ERROR);\
// Create more macros for structs with more attributes...
Then when you have a struct with const attributes, you can do this:
struct MyStruct
{
const int attr1;
const float attr2;
const double attr3;
};
const MyStruct test = CREATE_STRUCT_3(MyStruct, test, attr1, 1, attr2, 2.f, attr3, 3.);
It's a bit inconvenient, because you need macros for every possible number of attributes and you need to repeat the type and name of your instance in the macro call. Also you cannot use the macro in a return statement, because the asserts come after the initialization.
But it does solve your problem: When you change the struct, the call will fail at compile-time.
If you use C++17, you can even make these macros more strict by forcing the same types, e.g.:
#define CREATE_STRUCT_3(type, identifier, m_1, p_1, m_2, p_2, m_3, p_3) \
{ p_1, p_2, p_3 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_2) >= sizeof(identifier.m_1), INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_3) >= (offsetof(type, m_2) + sizeof(identifier.m_2)), INVALID_STRUCT_ERROR);\
static_assert(typeid(p_1) == typeid(identifier.m_1), INVALID_STRUCT_ERROR);\
static_assert(typeid(p_2) == typeid(identifier.m_2), INVALID_STRUCT_ERROR);\
static_assert(typeid(p_3) == typeid(identifier.m_3), INVALID_STRUCT_ERROR);\
You could put your text in a select statement such as...
SELECT 'Querying Table1' FROM dual;
<div id="my_id" class="my_class"></div>
if that is the first div then address it like so:
document.write("div CSS class: " + document.getElementsByTagName('div')[0].className);
alternatively do this:
document.write("alternative way: " + document.getElementById('my_id').className);
It yields the following results:
div CSS class: my_class
alternative way: my_class

I use this code, it works nice
html, body {
height: 100%;
width: 100%;
padding: 0;
margin: 0;
background: black url(back2.png) center center no-repeat;;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
There is builtin procedure to check dependents:
For an example ,
Execute sp_depends @objname=N'ssc.RegDash_RoutingAct'
Oh my days!!
Feel so embarrassed but it is my first day on the C++.
I was getting the error because of two things.
I opened an empty project
I didn't add #include "stdafx.h"
It ran successfully on the win 32 console.
There is a class, Class
, that can do this:
Class c = Class.forName("MyClass"); // if you want to specify a class
Class c = this.getClass(); // if you want to use the current class
System.out.println("Package: "+c.getPackage()+"\nClass: "+c.getSimpleName()+"\nFull Identifier: "+c.getName());
If c
represented the class MyClass
in the package mypackage
, the above code would print:
Package: mypackage
Class: MyClass
Full Identifier: mypackage.MyClass
You can take this information and modify it for whatever you need, or go check the API for more information.
The reason I used a +
instead of a '*' is because a plus is defined as one or more of the preceding element, where an asterisk is zero or more. In this case we want a delimiter that's a little more concrete, so "one or more" spaces.
word[Aa]\s+word[Bb]\s+word[Cc]
will match:
wordA wordB wordC
worda wordb wordc
wordA wordb wordC
The words, in this expression, will have to be specific, and also in order (a, b, then c)
