Here are a few options for changing text / label sizes
library(ggplot2)
# Example data using mtcars
a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))
p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) +
geom_bar(stat="identity",position="dodge") +
geom_text(data = a, aes(label = mpg),
position = position_dodge(width=0.9), size=20)
The size
in the geom_text
changes the size of the geom_text
labels.
p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels
p <- p + theme(axis.title = element_text(size = 25)) # change axis titles
p <- p + theme(text = element_text(size = 10)) # this will change all text size
# (except geom_text)
For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?
Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text
sizes to theme
sizes.
So a horrible fix for uniform sizes is to scale by this ratio
geom.text.size = 7
theme.size = (14/5) * geom.text.size
ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) +
geom_bar(stat="identity",position="dodge") +
geom_text(data = a, aes(label = mpg),
position = position_dodge(width=0.9), size=geom.text.size) +
theme(axis.text = element_text(size = theme.size, colour="black"))
This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)

I feel a little uneasy to add more answers here. Decided to go for the most readable and minimal pure ruby approach, disregarding the nice benchmark from @ulysse-bn. While :class
mode is a copy of @user3869936, the :method
mode I don't see in any other answer here.
def snake_to_camel_case(str, mode: :class)
case mode
when :class
str.split('_').map(&:capitalize).join
when :method
str.split('_').inject { |m, p| m + p.capitalize }
else
raise "unknown mode #{mode.inspect}"
end
end
Result is:
[28] pry(main)> snake_to_camel_case("asd_dsa_fds", mode: :class)
=> "AsdDsaFds"
[29] pry(main)> snake_to_camel_case("asd_dsa_fds", mode: :method)
=> "asdDsaFds"
In my scenario, there was no process blocking the database under sp_who2. However, we discovered because the database is much larger than our other databases that pending processes were still running which is why the database under the availability group still displayed as red/offline after we tried to 'resume data'by right clicking the paused database.
To check if you still have processes running just execute this command: select percent complete from sys.dm_exec_requests where percent_complete > 0
Try this
`var url = "http://stackoverflow.com";
$(location).attr('href',url);`
Or you can do something like this
// similar behavior as an HTTP redirect
window.location.replace("http://stackoverflow.com");
// similar behavior as clicking on a link
window.location.href = "http://stackoverflow.com";
and add a return false at the end of your function call
In case it helps someone else, I was able to convert to an array by doing something like this,
JSONObject jsonObject = (JSONObject)new JSONParser().parse(jsonString);
((JSONArray) jsonObject).toArray()
...or you should be able to get the length
((JSONArray) myJsonArray).toArray().length
From the announcement Git 1.7.10 (April 2012):
git clone
learned--single-branch
option to limit cloning to a single branch (surprise!); tags that do not point into the history of the branch are not fetched.
Git actually allows you to clone only one branch, for example:
git clone -b mybranch --single-branch git://sub.domain.com/repo.git
Note: Also you can add another single branch or "undo" this action.
There is also this one:
hash = { foo: "bar", baz: "qux" }
hash.map(&:last) #=> ["bar", "qux"]
Why it works:
The &
calls to_proc
on the object, and passes it as a block to the method.
something {|i| i.foo }
something(&:foo)
If you ever run in a situation where you need to get the next char of the word using __next__()
, remember to create a string_iterator
and iterate over it and not the original string (it does not have the __next__() method)
In this example, when I find a char = [
I keep looking into the next word while I don't find ]
, so I need to use __next__
here a for loop over the string wouldn't help
myString = "'string' 4 '['RP0', 'LC0']' '[3, 4]' '[3, '4']'"
processedInput = ""
word_iterator = myString.__iter__()
for idx, char in enumerate(word_iterator):
if char == "'":
continue
processedInput+=char
if char == '[':
next_char=word_iterator.__next__()
while(next_char != "]"):
processedInput+=next_char
next_char=word_iterator.__next__()
else:
processedInput+=next_char

import * as fs from 'fs';
import * as path from 'path';
fs.readFile(path.join(__dirname, "filename.txt"), (err, data) => {
if (err) throw err;
console.log(data);
})
EDIT:
consider the project structure:
../readfile/
+-- filename.txt
+-- src
+-- index.js
+-- index.ts
consider the index.ts
:
import * as fs from 'fs';
import * as path from 'path';
function lookFilesInDirectory(path_directory) {
fs.stat(path_directory, (err, stat) => {
if (!err) {
if (stat.isDirectory()) {
console.log(path_directory)
fs.readdirSync(path_directory).forEach(file => {
console.log(`\t${file}`);
});
console.log();
}
}
});
}
let path_view = './';
lookFilesInDirectory(path_view);
lookFilesInDirectory(path.join(__dirname, path_view));
if you have in the readfile folder and run tsc src/index.ts && node src/index.js
, the output will be:
./
filename.txt
src
/home/andrei/scripts/readfile/src/
index.js
index.ts
that is, it depends on where you run the node.
the __dirname is directory name of the current module.
Actually… there is! Sort of. box-shadow
defaults to color
, just like border
does.
According to http://dev.w3.org/.../#the-box-shadow
The color is the color of the shadow. If the color is absent, the used color is taken from the ‘color’ property.
In practice, you have to change the color
property and leave box-shadow
without a color:

The bug mentioned in the comment below has since been fixed :)
The parenthesis are superfluous in your example. The pointer doesn't care whether there's an array involved - it only knows that its pointing to an int
int g[] = {9,8};
int (*j) = g;
could also be rewritten as
int g[] = {9,8};
int *j = g;
which could also be rewritten as
int g[] = {9,8};
int *j = &g[0];
a pointer-to-an-array would look like
int g[] = {9,8};
int (*j)[2] = &g;
//Dereference 'j' and access array element zero
int n = (*j)[0];
There's a good read on pointer declarations (and how to grok them) at this link here: http://www.codeproject.com/Articles/7042/How-to-interpret-complex-C-C-declarations
In Bash and zsh you can do this with Brace Expansion. This simply expands a list of items in braces. For example:
# echo {vanilla,chocolate,strawberry}-ice-cream
vanilla-ice-cream chocolate-ice-cream strawberry-ice-cream
So you can do your rename as follows:
mv {,new.}original.filename
as this expands to:
mv original.filename new.original.filename
Use setInverseBackgroundForced(true)
on the alert dialog builder to invert the background.

This page walks you through the basics of creating an async javascript function.
Since ES2017, asynchronous javacript functions are much easier to write. You should also read more on Promises.
Neither one. Use final class for Constants
declare them as public static final
and static import all constants wherever necessary.
public final class Constants {
private Constants() {
// restrict instantiation
}
public static final double PI = 3.14159;
public static final double PLANCK_CONSTANT = 6.62606896e-34;

Usage :
import static Constants.PLANCK_CONSTANT;
import static Constants.PI;//import static Constants.*;
public class Calculations {
public double getReducedPlanckConstant() {
return PLANCK_CONSTANT / (2 * PI);

join() is a instance method of java.lang.Thread class which we can use join() method to ensure all threads that started from main must end in order in which they started and also main should end in last. In other words waits for this thread to die.
Exception: join() method throws InterruptedException.
Thread state: When join() method is called on thread it goes from running to waiting state. And wait for thread to die.
synchronized block: Thread need not to acquire object lock before calling join() method i.e. join() method can be called from outside synchronized block.
Waiting time: join(): Waits for this thread to die.
public final void join() throws InterruptedException;
This method internally calls join(0). And timeout of 0 means to wait forever;
join(long millis) – synchronized method Waits at most millis milliseconds for this thread to die. A timeout of 0 means to wait forever.
public final synchronized void join(long millis)
throws InterruptedException;
public final synchronized void join(long millis, int nanos)
throws InterruptedException;
Example of join method
class MyThread implements Runnable {
public void run() {
String threadName = Thread.currentThread().getName();
Printer.print("run() method of "+threadName);
for(int i=0;i<4;i++){
Printer.print("i="+i+" ,Thread="+threadName);
}
}
}
public class TestJoin {
public static void main(String...args) throws InterruptedException {
Printer.print("start main()...");
MyThread runnable = new MyThread();
Thread thread1=new Thread(runnable);
Thread thread2=new Thread(runnable);
thread1.start();
thread1.join();
thread2.start();
thread2.join();
Printer.print("end main()");
}
}
class Printer {
public static void print(String str) {
System.out.println(str);
}
}
Output:
start main()...
run() method of Thread-0
i=0 ,Thread=Thread-0
i=1 ,Thread=Thread-0
i=2 ,Thread=Thread-0
i=3 ,Thread=Thread-0
run() method of Thread-1
i=0 ,Thread=Thread-1
i=1 ,Thread=Thread-1
i=2 ,Thread=Thread-1
i=3 ,Thread=Thread-1
end main()
Note: calling thread1.join() made main thread to wait until Thread-1 dies.
Let’s check a program to use join(long millis)
First, join(1000) will be called on Thread-1, but once 1000 millisec are up, main thread can resume and start thread2 (main thread won’t wait for Thread-1 to die).
class MyThread implements Runnable {
public void run() {
String threadName = Thread.currentThread().getName();
Printer.print("run() method of "+threadName);
for(int i=0;i<4;i++){
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
Printer.print("i="+i+" ,Thread="+threadName);
}
}
}
public class TestJoin {
public static void main(String...args) throws InterruptedException {
Printer.print("start main()...");
MyThread runnable = new MyThread();
Thread thread1=new Thread(runnable);
Thread thread2=new Thread(runnable);
thread1.start();
// once 1000 millisec are up,
// main thread can resume and start thread2.
thread1.join(1000);
thread2.start();
thread2.join();
Printer.print("end main()");
}
}
class Printer {
public static void print(String str) {
System.out.println(str);
}
}
Output:
start main()...

From IEEE floating-point exceptions in C++ :
This page will answer the following questions.
- My program just printed out 1.#IND or 1.#INF (on Windows) or nan or inf (on Linux). What happened?
- How can I tell if a number is really a number and not a NaN or an infinity?
- How can I find out more details at runtime about kinds of NaNs and infinities?
- Do you have any sample code to show how this works?
- Where can I learn more?
These questions have to do with floating point exceptions. If you get some strange non-numeric output where you're expecting a number, you've either exceeded the finite limits of floating point arithmetic or you've asked for some result that is undefined. To keep things simple, I'll stick to working with the double floating point type. Similar remarks hold for float types.
Debugging 1.#IND, 1.#INF, nan, and inf
If your operation would generate a larger positive number than could be stored in a double, the operation will return 1.#INF on Windows or inf on Linux. Similarly your code will return -1.#INF or -inf if the result would be a negative number too large to store in a double. Dividing a positive number by zero produces a positive infinity and dividing a negative number by zero produces a negative infinity. Example code at the end of this page will demonstrate some operations that produce infinities.
Some operations don't make mathematical sense, such as taking the square root of a negative number. (Yes, this operation makes sense in the context of complex numbers, but a double represents a real number and so there is no double to represent the result.) The same is true for logarithms of negative numbers. Both sqrt(-1.0) and log(-1.0) would return a NaN, the generic term for a "number" that is "not a number". Windows displays a NaN as -1.#IND ("IND" for "indeterminate") while Linux displays nan. Other operations that would return a NaN include 0/0, 0*8, and 8/8. See the sample code below for examples.
In short, if you get 1.#INF or inf, look for overflow or division by zero. If you get 1.#IND or nan, look for illegal operations. Maybe you simply have a bug. If it's more subtle and you have something that is difficult to compute, see Avoiding Overflow, Underflow, and Loss of Precision. That article gives tricks for computing results that have intermediate steps overflow if computed directly.
Key insights for me were: - ensure that label content comes after the input-radio field - I tweaked my css to make everything a little closer
.radio-inline+.radio-inline {
margin-left: 5px;
}
In C#/.NET 3.5 you could write a little program to do:
using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
{
string controller = context.ConnectedServer;
Console.WriteLine( "Domain Controller:" + controller );
}
This will list all the users in the current domain:
using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
{
using (UserPrincipal searchPrincipal = new UserPrincipal(context))
{
using (PrincipalSearcher searcher = new PrincipalSearcher(searchPrincipal))
{
foreach (UserPrincipal principal in searcher.FindAll())
{
Console.WriteLine( principal.SamAccountName);
}
}
}
}
Try this, it's working perfect for me.
$(document).mouseup(function (e)
{
var searchcontainer = $("#search_container");
if (!searchcontainer.is(e.target) // if the target of the click isn't the container...
&& searchcontainer.has(e.target).length === 0) // ... nor a descendant of the container
{
searchcontainer.hide();
}
});
A proper way to search for a substring is to use position
function instead of like
expression, which requires escaping %
, _
and an escape character (\
by default):
SELECT id FROM TAG_TABLE WHERE position(tag_name in 'aaaaaaaaaaa')>0;
The property pDoc.parentElement
or pDoc.parentNode
will get you the parent element.
In addition to the answers above, you should initialize the StringBuilder
with an appropriate capacity, especially that you already know it. For example:
int capacity = existingString.length() + n * appendableString.length();
StringBuilder builder = new StringBuilder(capacity);
Further to @pmg's answer, note that you can do both operations in one statement:
char mystr[] = "Nmy stringP";
char *p = mystr;
p++[strlen(p)-1] = 0;
This will likely work as expected but behavior is undefined in C standard.
There are the slideDown, slideUp, and slideToggle functions native to jquery 1.3+, and they work quite nicely...
https://api.jquery.com/category/effects/
You can use slideDown just like this:
$("test").slideDown("slow");
And if you want to combine effects and really go nuts I'd take a look at the animate function which allows you to specify a number of CSS properties to shape tween or morph into. Pretty fancy stuff, that.
You need to configure a raw HttpClient with SSL support, something like this:
@Test
public void givenAcceptingAllCertificatesUsing4_4_whenUsingRestTemplate_thenCorrect()
throws ClientProtocolException, IOException {
CloseableHttpClient httpClient
= HttpClients.custom()
.setSSLHostnameVerifier(new NoopHostnameVerifier())
.build();
HttpComponentsClientHttpRequestFactory requestFactory
= new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);
ResponseEntity<String> response
= new RestTemplate(requestFactory).exchange(
urlOverHttps, HttpMethod.GET, null, String.class);
assertThat(response.getStatusCode().value(), equalTo(200));
}
The only reason I can think of is you are adding it as string 'now()'
, not function call now()
.
Or whatever else typo.
SELECT NOW();
to see if it returns correct value?
With brand new css properties you can have even more flexibility with variables aka custom properties
.shape {
width:500px;
height:200px;
}
.shape .gradient-bg {
fill: url(#header-shape-gradient) #fff;
}
#header-shape-gradient {
--color-stop: #f12c06;
--color-bot: #faed34;
}
_x000D_
<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="none" class="shape">
<defs>
<linearGradient id="header-shape-gradient" x2="0.35" y2="1">
<stop offset="0%" stop-color="var(--color-stop)" />
<stop offset="30%" stop-color="var(--color-stop)" />
<stop offset="100%" stop-color="var(--color-bot)" />
</linearGradient>
</defs>
<g>
<polygon class="gradient-bg" points="0,0 100,0 0,66" />
</g>
</svg>
_x000D_
Just set a named variable for each stop
in gradient and then customize as you like in css. You can even change their values dynamically with javascript, like:
document.querySelector('#header-shape-gradient').style.setProperty('--color-stop', "#f5f7f9");
Here's a more concise approach...
df['a_bsum'] = df.groupby('A')['B'].transform(sum)
df.sort(['a_bsum','C'], ascending=[True, False]).drop('a_bsum', axis=1)
The first line adds a column to the data frame with the groupwise sum. The second line performs the sort and then removes the extra column.
Result:
A B C
5 baz -2.301539 True
2 baz -0.528172 False
1 bar -0.611756 True
4 bar 0.865408 False
3 foo -1.072969 True
0 foo 1.624345 False
NOTE: sort
is deprecated, use sort_values
instead
Sometimes you want element.constructor.name
document.createElement('div').constructor.name
// HTMLDivElement
document.createElement('a').constructor.name
// HTMLAnchorElement
document.createElement('foo').constructor.name
// HTMLUnknownElement

The only thing you can do is obfuscate your code to make it more difficult to read. No matter what you do, if you want the javascript to execute in their browser they'll have to have the code.
charAt do not work if it has a parent prop

use parent.child.slice(0, 1)
Here's some working C++ code which solves the problem.
Proof that the memory constraints are satisfied:
Editor: There is no proof of the maximum memory requirements offered by the author either in this post or in his blogs. Since the number of bits necessary to encode a value depends on the values previously encoded, such a proof is likely non-trivial. The author notes that the largest encoded size he could stumble upon empirically was 1011732
, and chose the buffer size 1013000
arbitrarily.
typedef unsigned int u32;
namespace WorkArea
{
static const u32 circularSize = 253250;
u32 circular[circularSize] = { 0 }; // consumes 1013000 bytes
static const u32 stageSize = 8000;
u32 stage[stageSize]; // consumes 32000 bytes
...
Together, these two arrays take 1045000 bytes of storage. That leaves 1048576 - 1045000 - 2×1024 = 1528 bytes for remaining variables and stack space.
It runs in about 23 seconds on my Xeon W3520. You can verify that the program works using the following Python script, assuming a program name of sort1mb.exe
.
from subprocess import *
import random
sequence = [random.randint(0, 99999999) for i in xrange(1000000)]
sorter = Popen('sort1mb.exe', stdin=PIPE, stdout=PIPE)
for value in sequence:
sorter.stdin.write('%08d\n' % value)
sorter.stdin.close()
result = [int(line) for line in sorter.stdout]
print('OK!' if result == sorted(sequence) else 'Error!')

in phpmyadmin you can easily rename the database
select database
goto operations tab
in that rename Database to :
type your new database name and click go
ask to drop old table and reload table data click OK in both
Your database is renamed
you can use :target
or to filter by class name, use .classname:target
or filter by id name using #idname:target

Current page: It's possible to do even shorter. This single line sound more elegant to find the current page's file name:
var fileName = location.href.split("/").slice(-1);
or...
var fileName = location.pathname.split("/").slice(-1)
This is cool to customize nav box's link, so the link toward the current is enlighten by a CSS class.
JS:
$('.menu a').each(function() {
if ($(this).attr('href') == location.href.split("/").slice(-1)){ $(this).addClass('curent_page'); }
});
CSS:
a.current_page { font-size: 2em; color: red; }

Using the Range.Find method, as pointed out above, along with a loop for each worksheet in the workbook, is the fastest way to do this. The following, for example, locates the string "Question?" in each worksheet and replaces it with the string "Answered!".
Sub FindAndExecute()
Dim Sh As Worksheet
Dim Loc As Range
For Each Sh In ThisWorkbook.Worksheets
With Sh.UsedRange
Set Loc = .Cells.Find(What:="Question?")
If Not Loc Is Nothing Then
Do Until Loc Is Nothing
Loc.Value = "Answered!"
Set Loc = .FindNext(Loc)
Loop
End If
End With
Set Loc = Nothing
Next
End Sub

I finally fixed this using the Google's camera app. It gets the phone's orientation by using a sensor and then sets the EXIF tag appropriately. The JPEG which comes out of the camera is not oriented automatically.
Also, the camera preview works properly only in the landscape mode. If you need your activity layout to be oriented in portrait, you will have to do it manually using the value from the orientation sensor.

yes,the sorting proceed differently. in first scenario, orders based on column1 and in addition to that process further by sorting colmun2 based on column1 .. in second scenario ,it orders completely based on column 1 only... please proceed with a simple example...u will get quickly..
If you are using the Google Chrome driver, you can use this very simple code (it worked for me):
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--headless")
driver = webdriver.Chrome('chromedriver2_win32/chromedriver.exe', options=chrome_options)
driver.get('https://www.anywebsite.com')
import psutil
pid_list=psutil.get_pid_list()
print pid_list
p = psutil.Process(1052)
print p.name
for i in pid_list:
p = psutil.Process(i)
p_name=p.name
print str(i)+" "+str(p.name)
if p_name=="PerfExp.exe":
print "*"*20+" mam ho "+"*"*20
p.kill()
As Bevan said, but keep in mind, that the list-index is 0-based. If you want to move an element to the front of the list, you have to insert it at index 0 (not 1 as shown in your example).
This will round down correctly as well:
>>> n = 46
>>> rem = n % 10
>>> if rem < 5:
... n = int(n / 10) * 10
... else:
... n = int((n + 10) / 10) * 10
...
>>> 50
maybe this works?

I have this array as my request data from a HTML+Vue.js data grid/table:
[0] => Array
(
[item_id] => 1
[item_no] => 3123
[size] => 3e
)
[1] => Array
(
[item_id] => 2
[item_no] => 7688
[size] => 5b
)
And use this to validate which works properly:
$this->validate($request, [
'*.item_id' => 'required|integer',
'*.item_no' => 'required|integer',
'*.size' => 'required|max:191',
]);
If you are not using programming then do the following (1) select the column (2) right click and select Format Cells (3) Select "Custom" (4) Just Under "Type:" type dd/mm/yyyy hh:mm:ss
Here is a trick if you want to calculate maximum(field, 0):
SELECT (ABS(field) + field)/2 FROM Table
returns 0 if field
is negative, else, return field
.
Query-strings can be ignored by search engines.
From find manual:
NON-BUGS
Operator precedence surprises
The command find . -name afile -o -name bfile -print will never print
afile because this is actually equivalent to find . -name afile -o \(
-name bfile -a -print \). Remember that the precedence of -a is
higher than that of -o and when there is no operator specified
between tests, -a is assumed.
“paths must precede expression” error message
$ find . -name *.c -print
find: paths must precede expression
Usage: find [-H] [-L] [-P] [-Olevel] [-D ... [path...] [expression]
This happens because *.c has been expanded by the shell resulting in
find actually receiving a command line like this:
find . -name frcode.c locate.c word_io.c -print
That command is of course not going to work. Instead of doing things
this way, you should enclose the pattern in quotes or escape the
wildcard:
$ find . -name '*.c' -print
$ find . -name \*.c -print
If the comment message includes non-English characters, using method provided by user456814, those characters will be replaced by question marks. (tested under sourcetree Ver2.5.5.0)
So I have to use the following method.
CAUTION: if the commit has been pulled by other members, changes below might cause chaos for them.
Step1: In the sourcetree main window, locate your repo tab, and click the "terminal" button to open the git command console.
Step2:
[Situation A]: target commit is the latest one.
1) In the git command console, input
git commit --amend -m "new comment message"
2) If the target commit has been pushed to remote, you have to push again by force. In the git command console, input
git push --force
[Situation B]: target commit is not the latest one.
1) In the git command console, input
git rebase -i HEAD~n
It is to squash the latest n commits. e.g. if you want to edit the message before the last one, n is 2.
This command will open a vi window, the first word of each line is "pick", and you change the "pick" to "reword" for the line you want to edit. Then, input :wq
to save&quit that vi window. Now, a new vi window will be open, in this window you input your new message. Also use :wq
to save&quit.
2) If the target commit has been pushed to remote, you have to push again by force. In the git command console, input
git push --force
Finally: In the sourcetree main window, Press F5
to refresh.

Just use $(selector).is(':checked')
It returns a boolean value.

Maybe an example from ruby can help:
You can include the mixin Comparable
and define one function "<=>(other)"
, the mixin provides all those functions:
<(other)
>(other)
==(other)
<=(other)
>=(other)
between?(other)
It does this by invoking <=>(other)
and giving back the right result.
"instance <=> other"
returns 0 if both objects are equal, less than 0 if instance
is bigger than other
and more than 0 if other
is bigger.
Duplicate your table into a table to be archived:
SELECT * INTO ArchiveTable FROM MyTable
Delete all entries in your table:
DELETE * FROM MyTable
Since the permission policy on my device is a bit paranoid (cannot adb pull
application data), I wrote a script to copy files recursively.
Note: this recursive file/folder copy script is intended for Android!
copy-r:
#! /system/bin/sh

dst="$2"
dir0=`pwd`
myfind() {
local fpath=$1
if [ -e "$fpath" ]
then
echo $fpath

then
for fn in $fpath/*
do
myfind $fn
done
fi
else
: echo "$fpath not found"
fi
}
if [ ! -z "$dst" ]
then
if [ -d "$src" ]
then
echo 'the source is a directory'
mkdir -p $dst
if [[ "$dst" = /* ]]
then
: # Absolute path
else
# Relative path
dst=`pwd`/$dst
fi
cd $src
echo "COPYING files and directories from `pwd`"
for fn in $(myfind .)
do
if [ -d $fn ]
then
echo "DIR $dst/$fn"
mkdir -p $dst/$fn
else
echo "FILE $dst/$fn"
cat $fn >$dst/$fn
fi
done
echo "DONE"
cd $dir0
elif [ -f "$src" ]
then
echo 'the source is a file'
srcn="${src##*/}"
if [ -z "$srcn" ]
then

then
mkdir -p $dst
echo "copying $src" '->' "$dst/$srcn"
cat $src >$dst/$srcn
elif [ -d "$dst" ]
then

Here I provide the source of a lightweight find
for Android because on some devices this utility is missing. Instead of myfind
one can use find
, if it is defined on the device.
Installation:
$ adb push copy-r /sdcard/
Running within adb shell
(rooted):
# . /sdcard/copy-r files/ /sdcard/files3
or
# source /sdcard/copy-r files/ /sdcard/files3
(The hash #
above is the su
prompt, while .
is the command that causes the shell to run the specified file, almost the same as source
).
After copying, I can adb pull
the files from the sd-card.
Writing files to the app directory was trickier, I tried to set r/w permissions on files
and its subdirectories, it did not work (well, it allowed me to read, but not write, which is strange), so I had to do:
String[] cmdline = { "sh", "-c", "source /sdcard/copy-r /sdcard/files4 /data/data/com.example.myapp/files" };
try {
Runtime.getRuntime().exec(cmdline);
} catch (IOException e) {
e.printStackTrace();
}
in the application's onCreate().
PS just in case someone needs the code to unprotect application's directories to enable adb shell
access on a non-rooted phone,
setRW(appContext.getFilesDir().getParentFile());
public static void setRW(File... files) {
for (File file : files) {
if (file.isDirectory()) {
setRW(file.listFiles()); // Calls same method again.
} else {
}
file.setReadable(true, false);
file.setWritable(true, false);
}
}
although for some unknown reason I could read but not write.
On @Sorin's suggestion of the Java Pattern docs, it looks like chars to escape are at least:
\.[{(*+?^$|
SQL - Structured Query Language. It is declarative computer language aimed at querying relational databases.
MySQL is a relational database - a piece of software optimized for data storage and retrieval. There are many such databases - Oracle, Microsoft SQL Server, SQLite and many others are examples of such.
Extending other answers:
I found @GEverding's answer most flexible. It also works with aggregation:
test_db.js
print("name,email");
db.users.aggregate([
{ $match: {} }
]).forEach(function(user) {
print(user.name+","+user.email);
}
});
Execute the following command to export results:
mongo test_db < ./test_db.js >> ./test_db.csv
Unfortunately, it adds additional text to the CSV file which requires processing the file before we can use it:
MongoDB shell version: 3.2.10
connecting to: test_db
But we can make mongo shell stop spitting out those comments and only print what we have asked for by passing the --quiet
flag
mongo --quiet test_db < ./test_db.js >> ./test_db.csv
Even though the above answer appears to be correct, I wanted to add a (hopefully) more readable example that also stays in 3 columns form at different widths:
.flex-row-container {_x000D_

display: flex;_x000D_
flex-wrap: wrap;_x000D_

string stringSeparators = "\r\n";
string text = sr.ReadToEnd();
string lines = text.Replace(stringSeparators, "");
lines = lines.Replace("\\r\\n", "\r\n");
Console.WriteLine(lines);
The first replace replaces the \r\n
from the text file's new lines, and the second replaces the actual \r\n
text that is converted to \\r\\n
when the files is read. (When the file is read \
becomes \\
).
Take a look at the open source WordPress application. They have a very re-usable window they have created for displaying an "activity in progress" type display over top of whatever view your application is currently displaying.
http://iphone.trac.wordpress.org/browser/trunk
The files you want are:
Then to show it use something like:
[[WPActivityIndicator sharedActivityIndicator] show];
And hide with:
[[WPActivityIndicator sharedActivityIndicator] hide];
int num = 1;
num.ToString("0000");
Option 1
Open a different console and run
jupyter notebook stop [PORT]
The default [PORT] is 8888, so, assuming that Jupyter Notebooks is running on port 8888, just run
jupyter notebook stop
If it is on port 9000, then
jupyter notebook stop 9000
Option 2 (Source)
Check runtime folder location
jupyter --paths
Remove all files in the runtime folder
rm -r [RUNTIME FOLDER PATH]/*
Use top
to find any Jupyter Notebook running processes left and if so kill their PID.
top | grep jupyter &
kill [PID]
One can boilt it down to
TARGET_PORT=8888
kill -9 $(lsof -n -i4TCP:$TARGET_PORT | cut -f 2 -d " ")
Note: If one wants to launch one's Notebook on a specific IP/Port
jupyter notebook --ip=[ADD_IP] --port=[ADD_PORT] --allow-root &
Another hints for Unexpected token
errors.
There are two major differences between javascript objects and json:
Correct JSON
{
"english": "bag",
"kana": "kaban",
"kanji": "K"
}
Error JSON 1
{
'english': 'bag',
'kana': 'kaban',
'kanji': 'K'
}
Error JSON 2
{
english: "bag",
kana: "kaban",
kanji: "K"
}
Remark
This is not a direct answer for that question. But it's an answer for Unexpected token
errors. So it may be help others who stumple upon that question.
A closure is a block of code that can be referenced (and passed around) with access to the variables of the enclosing scope.
Since Java 1.1, anonymous inner class have provided this facility in a highly verbose manner. They also have a restriction of only being able to use final
(and definitely assigned) local variables. (Note, even non-final
local variables are in scope, but cannot be used.)
Java SE 8 is intended to have a more concise version of this for single-method interfaces*, called "lambdas". Lambdas have much the same restrictions as anonymous inner classes, although some details vary randomly.
Lambdas are being developed under Project Lambda and JSR 335.
*Originally the design was more flexible allowing Single Abstract Methods (SAM) types. Unfortunately the new design is less flexible, but does attempt to justify allowing implementation within interfaces.
It is at the same location: ~/.android/debug.keystore
Here is another way that uses the 2-element data constructor. No functions are needed to initialize it. There is no 3rd party code (Boost), no static functions or objects, no tricks, just simple C++:
#include <map>
#include <string>
typedef std::map<std::string, int> MyMap;
const MyMap::value_type rawData[] = {
MyMap::value_type("hello", 42),
MyMap::value_type("world", 88),
};
const int numElems = sizeof rawData / sizeof rawData[0];
MyMap myMap(rawData, rawData + numElems);
Since I wrote this answer C++11 is out. You can now directly initialize STL containers using the new initializer list feature:
const MyMap myMap = { {"hello", 42}, {"world", 88} };
I had been using the method in Jon Skeet's answer, but another one occurred to me using Concat
. The Concat
method performed slightly better in a limited test, but it's a hassle and I'll probably just stick with Contains
, or maybe I'll write a helper method to do this for me. Either way, here's another option if anyone is interested:
// Given an array of id's
var ids = new Guid[] { ... };
// and a DataContext
var dc = new MyDataContext();
// start the queryable
var query = (
from thing in dc.Things
where thing.Id == ids[ 0 ]
select thing
);
// then, for each other id
for( var i = 1; i < ids.Count(); i++ ) {
// select that thing and concat to queryable
query.Concat(
from thing in dc.Things
where thing.Id == ids[ i ]
select thing
);
}
This was not remotely scientific. I imagine your database structure and the number of IDs involved in the list would have a significant impact.
I set up a test where I did 100 trials each of Concat
and Contains
where each trial involved selecting 25 rows specified by a randomized list of primary keys. I've run this about a dozen times, and most times the Concat
method comes out 5 - 10% faster, although one time the Contains
method won by just a smidgen.
Cron jobs usually are stored in a per-user file under /var/spool/cron
The simplest thing for you to do is probably just create a text file with the job configured, then copy it to the cron spool folder and make sure it has the right permissions (600).
I know this is an old post but I thought I might add a thought for people who come across a similar problem. I'm assuming that you are using ASP.NET MVC since you mentioned site.css.
Check your Bundles.config file to see if you have BundleTable.EnableOptimizations = true
; If you don't, then it can be your problem since this allows the program to be bundles and "minified". Depending on if you run in debug mode or not this could have an effect.
line2 = "hello 12 hi 89"
temp1 = re.findall(r'\d+', line2) # through regular expression
res2 = list(map(int, temp1))
print(res2)
Hi ,
you can search all the integers in the string through digit by using findall expression .
In the second step create a list res2 and add the digits found in string to this list
hope this helps

Just wanted to summarize all the correct answers above in short. Because I had to spend lot of time to figure out which answer resolves the issue and what's going on behind the scenes.
There seems to be two problems of fieldset with bootstrap:
bootstrap
sets the width to the legend
as 100%. That is why it overlays the top border of the fieldset
. bottom border
for the legend
.So, all we need to fix this is set the legend width to auto as follows:
legend.scheduler-border {
width: auto; // fixes the problem 1
border-bottom: none; // fixes the problem 2
}
I had the same issue, so I've disabled one setting on my WHM root login, which is as follows :

You can use scriptlets, however, this is not the way to go. Nowdays inline scriplets or JAVA code in your JSP files is considered a bad habit.
You should read up on JSTL a bit more. If the ansokanInfo object is in your request or session scope, printing the object (toString() method) like this: ${ansokanInfo} can give you some base information. ${ansokanInfo.pSystem} should call the object getter method. If this all works, you can use this:
<c:if test="${ ansokanInfo.pSystem == 'NAT'}"> tataa </c:if>
With RHEL 7 / CentOS 7, firewalld was introduced to manage iptables. IMHO, firewalld is more suited for workstations than for server environments.
It is possible to go back to a more classic iptables setup. First, stop and mask the firewalld service:
systemctl stop firewalld
systemctl mask firewalld
Then, install the iptables-services package:
yum install iptables-services
Enable the service at boot-time:
systemctl enable iptables
Managing the service
systemctl [stop|start|restart] iptables
Saving your firewall rules can be done as follows:
service iptables save
or
/usr/libexec/iptables/iptables.init save
One way to automatically do this is the bbox_inches='tight'
kwarg to plt.savefig
.
E.g.
import matplotlib.pyplot as plt
import numpy as np
data = np.arange(3000).reshape((100,30))
plt.imshow(data)
plt.savefig('test.png', bbox_inches='tight')
Another way is to use fig.tight_layout()
import matplotlib.pyplot as plt
import numpy as np
xs = np.linspace(0, 1, 20); ys = np.sin(xs)
fig = plt.figure()
axes = fig.add_subplot(1,1,1)
axes.plot(xs, ys)
# This should be called after all axes have been added
fig.tight_layout()
fig.savefig('test.png')
Even if the equals method were comparing those two fields, then logically, it would be just the same code as you doing it manually. OK, it might be "messy", but it's still the correct answer
When the user session times out, I send back an HTTP 204 status code. Note that the HTTP 204 status contains no content. On the client-side I do this:

I am trying to obtain a handle on one of the views in the Action Bar
I will assume that you mean something established via android:actionLayout
in your <item>
element of your <menu>
resource.
I have tried calling findViewById(R.id.menu_item)
To retrieve the View
associated with your android:actionLayout
, call findItem()
on the Menu
to retrieve the MenuItem
, then call getActionView()
on the MenuItem
. This can be done any time after you have inflated the menu resource.
Another option is:
for i in *001.jpg
do
echo "mv $i yourstring${i#*001.jpg}"
done
remove echo
after you have it right.
Parameter substitution with #
will keep only the last part, so you can change its name.
Running your code shows an image for me, after adjusting the path. Can you verify that your image path is correct, try absolute path for instance?
Or just use a regular for loop instead of foreach. A for loop is slightly faster (though you won't notice the difference except in very time critical code).
You can also use openssl
to accomplish the same thing:
$ openssl pkcs12 -nokeys -info \
-in </path/to/file.pfx> \
-passin pass:<pfx's password>

For me I solved it by changing passwords from Arabic letter to English letter, but first I went to the folder and deleted the generated key then it works.
For most common markdown generators. You have a simple self generated anchor in each header. For instance with pandoc, the generated anchor will be a kebab case slug of your header.
echo "# Hello, world\!" | pandoc
# => <h1 id="hello-world">Hello, world!</h1>
Depending on which markdown parser you use, the anchor can change (take the exemple of symbolrush and La muerte Peluda answers, they are different!). See this babelmark where you can see generated anchors depending on your markdown implementation.
You can do this 2 ways, via js or html (easist)
$('.carousel').carousel({
interval: false,
});
That will make the auto sliding stop because there no Milliseconds added and will never slider next.
data-interval="false"
and removing data-ride="carousel"
<div id="carouselExampleCaptions" class="carousel slide" data-ride="carousel">
becomes:
<div id="carouselExampleCaptions" class="carousel slide" data-interval="false">

The openssl
documentation says that file supplied as the -in
argument must be in PEM format.
Turns out that, contrary to the CA's manual, the certificate returned by the CA which I stored in myCert.cer
is not PEM format rather it is PKCS7.
In order to create my .p12
, I had to first convert the certificate to PEM:
openssl pkcs7 -in myCert.cer -print_certs -out certs.pem
and then execute
openssl pkcs12 -export -out keyStore.p12 -inkey myKey.pem -in certs.pem
you can use html radio/checkbox input with labels and css to achieve the expanding effects you want.
I run into the same problem and wrote a little shared-memory utility class to work around it.
I'm using multiprocessing.RawArray
(lockfree), and also the access to the arrays is not synchronized at all (lockfree), be careful not to shoot your own feet.
With the solution I get speedups by a factor of approx 3 on a quad-core i7.
Here's the code: Feel free to use and improve it, and please report back any bugs.

Just use git show <tag>

Thanks for your great question, this has caught me out a few times. When using dataURI HTML source, I find that I have to define a complete HTML document.
See below a modified example.
var html = '<html><head></head><body>Foo</body></html>';
var iframe = document.createElement('iframe');
iframe.src = 'data:text/html;charset=utf-8,' + encodeURI(html);
take note of the html content wrapped with <html>
tags and the iframe.src
string.
The iframe element needs to be added to the DOM tree to be parsed.
document.body.appendChild(iframe);
You will not be able to inspect the iframe.contentDocument
unless you disable-web-security
on your browser.
You'll get a message
DOMException: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Blocked a frame with origin "http://localhost:7357" from accessing a cross-origin frame.
js version, catches iPad too:
var is_mobile = /mobile|android/i.test (navigator.userAgent);
I've been struggling with this problem in one form or another for AGES, thank you, Thank You, THANK YOU.... :)
I just wanted to point out that you can get a generalizable solution from what Bob Lee's done by just extending View and overriding onMeasure. That way you can use this with any drawable you want, and it won't break if there's no image:
public class CardImageView extends View {
public CardImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public CardImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CardImageView(Context context) {
super(context);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
Drawable bg = getBackground();
if (bg != null) {
int width = MeasureSpec.getSize(widthMeasureSpec);
int height = width * bg.getIntrinsicHeight() / bg.getIntrinsicWidth();
setMeasuredDimension(width,height);
}
else {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
}
ORDER BY column OFFSET 0 ROWS
Surprisingly makes it work, what a strange feature.
A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:
;WITH cte AS (
SELECT .....long select statement here....
)
SELECT * FROM
(
SELECT * FROM
( -- necessary to nest selects for union to work with where & order clauses
SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS
) first
UNION ALL
SELECT * FROM
(
SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS
) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example
So we get all results ordered by MainCol
But the results with MainCol = 1
get ordered by ColX
And the results with MainCol = 0
get ordered by ColY
There's no need to use jQuery because this is native JavaScript functionality
element.scrollIntoView()
You can use awk:
awk '{ sum += $1 } END { print sum }' file
You can set the draggable
attribute to false
in either the markup or JavaScript code.
// As a jQuery method: $('#myImage').attr('draggable', false);_x000D_
document.getElementById('myImage').setAttribute('draggable', false);
_x000D_
<img id="myImage" src="http://placehold.it/150x150">
_x000D_
To assign value to a single Form control/individually, I propose to use setValue in the following way:
this.editqueForm.get('user').setValue(this.question.user);
this.editqueForm.get('questioning').setValue(this.question.questioning);
Parsing JSON in Rails is quite straightforward:
parsed_json = ActiveSupport::JSON.decode(your_json_string)
Let's suppose, the object you want to associate the shortUrl with is a Site object, which has two attributes - short_url and long_url. Than, to get the shortUrl and associate it with the appropriate Site object, you can do something like:
parsed_json["results"].each do |longUrl, convertedUrl|
site = Site.find_by_long_url(longUrl)
site.short_url = convertedUrl["shortUrl"]
site.save
end
You should build your own Authorize-filter attribute.
Here's mine to study ;)
Public Class RequiresRoleAttribute : Inherits ActionFilterAttribute
Private _role As String
Public Property Role() As String
Get
Return Me._role
End Get
Set(ByVal value As String)
Me._role = value
End Set
End Property
Public Overrides Sub OnActionExecuting(ByVal filterContext As System.Web.Mvc.ActionExecutingContext)
If Not String.IsNullOrEmpty(Me.Role) Then
If Not filterContext.HttpContext.User.Identity.IsAuthenticated Then
Dim redirectOnSuccess As String = filterContext.HttpContext.Request.Url.AbsolutePath
Dim redirectUrl As String = String.Format("?ReturnUrl={0}", redirectOnSuccess)
Dim loginUrl As String = FormsAuthentication.LoginUrl + redirectUrl
filterContext.HttpContext.Response.Redirect(loginUrl, True)
Else
Dim hasAccess As Boolean = filterContext.HttpContext.User.IsInRole(Me.Role)
If Not hasAccess Then
Throw New UnauthorizedAccessException("You don't have access to this page. Only " & Me.Role & " can view this page.")
End If
End If
Else
Throw New InvalidOperationException("No Role Specified")
End If
End Sub
End Class
Functions cannot be used to modify base table information, use a stored procedure.

Against all expectation, views are way slower in some circumstances.
I discovered this recently when I had problems with data which was pulled from Oracle which needed to be massaged into another format. Maybe 20k source rows. A small table. To do this we imported the oracle data as unchanged as I could into a table and then used views to extract data. We had secondary views based on those views. Maybe 3-4 levels of views.
One of the final queries, which extracted maybe 200 rows would take upwards of 45 minutes! That query was based on a cascade of views. Maybe 3-4 levels deep.
I could take each of the views in question, insert its sql into one nested query, and execute it in a couple of seconds.
We even found that we could even write each view into a temp table and query that in place of the view and it was still way faster than simply using nested views.
What was even odder was that performance was fine until we hit some limit of source rows being pulled into the database, performs just dropped off a cliff over the space of a couple of days - a few more source rows was all it took.
So, using queries which pull from views which pull from views is much slower than a nested query - which makes no sense for me.
During testing I found that foreach loop after break go to the loop beging and not out of the loop. So I changed foreach into for and break in this case work correctly- after break program flow goes out of the loop.
I was able to do that by using \n
in the line parameter.
It is specially useful if the file can be validated, and adding a single line generates an invalid file.
In my case, I was adding AuthorizedKeysCommand
and AuthorizedKeysCommandUser
to sshd_config, with the following command:
- lineinfile: dest=/etc/ssh/sshd_config line='AuthorizedKeysCommand /etc/ssh/ldap-keys\nAuthorizedKeysCommandUser nobody' validate='/usr/sbin/sshd -T -f %s'
Adding only one of the options generates a file that fails validation.
Addionally to @Bothwells answer (which I prefer) for single values, in order to null-checking assingment of function return values, you can use new walrus-operator (since python3.8):
def test():
return
a = 2 if (x:= test()) is None else x
Thus, test
function does not need to be evaluated two times (as in a = 2 if test() is None else test()
)
Follow this steps:
-Build
-Generate Signed Apk
-Create new
Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)
Swift Version tested:
//Somewhere in your UIViewController, like viewDidLoad(){ ... }
self.textField.addTarget(
self,
action: #selector(SearchViewController.textFieldDidChange(_:)),
forControlEvents: UIControlEvents.EditingChanged
)
Parameters explained:
self.textField //-> A UITextField defined somewhere in your UIViewController
self //-> UIViewController
.textFieldDidChange(_:) //-> Can be named anyway you like, as long as it is defined in your UIViewController
Then add the method you created above in your UIViewController
:
//Gets called everytime the text changes in the textfield.
func textFieldDidChange(textField: UITextField){
print("Text changed: " + textField.text!)
}
Years ago, when mailing functionality was introduced, so that was utterly text based, as the time passed, need for attachments like image and media (audio,video etc) came into existence. When these attachments are sent over internet (which is basically in the form of binary data), the probability of binary data getting corrupt is high in its raw form. So, to tackle this problem BASE64 came along.
The problem with binary data is that it contains null characters which in some languages like C,C++ represent end of character string so sending binary data in raw form containing NULL bytes will stop a file from being fully read and lead in a corrupt data.
For Example :
In C and C++, this "null" character shows the end of a string. So "HELLO" is stored like this:
H E L L O
72 69 76 76 79 00
The 00 says "stop here".
Now let’s dive into how BASE64 encoding works.
Point to be noted : Length of the string should be in multiple of 3.
Example 1 :
String to be encoded : “ace”, Length=3
1) Convert each character to decimal.
a= 97, c= 99, e= 101
2) Change each decimal to 8-bit binary representation.
97= 01100001, 99= 01100011, 101= 01100101
Combined : 01100001 01100011 01100101
3) Seperate in a group of 6-bit.
011000 010110 001101 100101
4) Calculate binary to decimal
011000= 24, 010110= 22, 001101= 13, 100101= 37
5) Covert decimal characters to base64 using base64 chart.
24= Y, 22= W, 13= N, 37= l
“ace” => “YWNl”
Example 2 :
String to be encoded : “abcd” Length=4, it's not multiple of 3. So to make string length multiple of 3 , we must add 2 bit padding to make length= 6. Padding bit is represented by “=” sign.
Point to be noted : One padding bit equals two zeroes 00 so two padding bit equals four zeroes 0000.
So lets start the process :–
1) Convert each character to decimal.
a= 97, b= 98, c= 99, d= 100
2) Change each decimal to 8-bit binary representation.
97= 01100001, 98= 01100010, 99= 01100011, 100= 01100100
3) Separate in a group of 6-bit.
011000, 010110, 001001, 100011, 011001, 00
so the last 6-bit is not complete so we insert two padding bit which equals four zeroes “0000”.
011000, 010110, 001001, 100011, 011001, 000000 ==
Now, it is equal. Two equals sign at the end show that 4 zeroes were added (helps in decoding).
4) Calculate binary to decimal.
011000= 24, 010110= 22, 001001= 9, 100011= 35, 011001= 25, 000000=0 ==
5) Covert decimal characters to base64 using base64 chart.
24= Y, 22= W, 9= j, 35= j, 25= Z, 0= A ==
“abcd” => “YWJjZA==”
The least painful and indeed Django-recommended way of doing this is through a OneToOneField(User)
property.
Extending the existing User model
…
If you wish to store information related to
User
, you can use a one-to-one relationship to a model containing the fields for additional information. This one-to-one model is often called a profile model, as it might store non-auth related information about a site user.
That said, extending django.contrib.auth.models.User
and supplanting it also works...
Substituting a custom User model
Some kinds of projects may have authentication requirements for which Django’s built-in
User
model is not always appropriate. For instance, on some sites it makes more sense to use an email address as your identification token instead of a username.[Ed: Two warnings and a notification follow, mentioning that this is pretty drastic.]
I would definitely stay away from changing the actual User class in your Django source tree and/or copying and altering the auth module.
Check out this MD5 implementation for JavaScript. Its BSD Licensed and really easy to use. Example:
md5 = hex_md5("message to digest")
David Wolever's solution is good, but
If you want to have signed angles you have to determine if a given pair is right or left handed (see wiki for further info).
My solution for this is:
def unit_vector(vector):
""" Returns the unit vector of the vector"""
return vector / np.linalg.norm(vector)
def angle(vector1, vector2):
""" Returns the angle in radians between given vectors"""
v1_u = unit_vector(vector1)
v2_u = unit_vector(vector2)
minor = np.linalg.det(
np.stack((v1_u[-2:], v2_u[-2:]))
)
if minor == 0:
raise NotImplementedError('Too odd vectors =(')
return np.sign(minor) * np.arccos(np.clip(np.dot(v1_u, v2_u), -1.0, 1.0))
It's not perfect because of this NotImplementedError
but for my case it works well. This behaviour could be fixed (cause handness is determined for any given pair) but it takes more code that I want and have to write.
There is no such attribute in Android, to show a shadow. But possible ways to do it are:
Add a plain LinearLayout with grey color, over which add your actual layout, with margin at bottom and right equal to 1 or 2 dp
Have a 9-patch image with a shadow and set it as the background to your Linear layout
You clone a repository with
git clone [url]
For example, if you want to clone the Stanford University Drupal Open Framework Git library called open_framework, you can do so like this:
$ git clone git://github.com/SU-SWS/open_framework.git
That creates a directory named open_framework (at your current local file system location), initializes a .git directory inside it, pulls down all the data for that repository, and checks out a working copy of the latest version. If you go into the newly created open_framework directory, you’ll see the project files in there, ready to be worked on or used.
If you want to clone the repository into a directory named something other than open_framework, you can specify that as the next command-line option:
$ git clone git:github.com/SU-SWS/open_framework.git mynewtheme
That command does the same thing as the previous one, but the target directory is called mynewtheme.
Git has a number of different transfer protocols you can use. The previous example uses the git:// protocol, but you may also see http(s):// or user@server:/path.git, which uses the SSH transfer protocol.
I use the AbsoluteUri and you can get it like this:
string myURI = Request.Url.AbsoluteUri;
if (!WebSecurity.IsAuthenticated) {
Response.Redirect("~/Login?returnUrl="
+ Request.Url.AbsoluteUri );
Then after you login:
var returnUrl = Request.QueryString["returnUrl"];
if(WebSecurity.Login(username,password,true)){
Context.RedirectLocal(returnUrl);
It works well for me.
Using for:
for each in "${alpha[@]}"
do
echo "$each"
done
Using history; note this will fail if your values contain !
:
history -p "${alpha[@]}"
Using basename; note this will fail if your values contain /
:
basename -a "${alpha[@]}"
Using shuf; note that results might not come out in order:
shuf -e "${alpha[@]}"
Use table style Border-collapse at the table level
If you don't have httpd.conf
in folder /etc/apache2
, you should have apache2.conf - simply add:
ServerName localhost
Then restart the apache2
service.
There are two different types of Java to download: The JDK, which is used to write Java programs, and the RE (runtime environment), which is used to actually run Java programs. Are you sure that you installed the RE instead of the SDK?
+=
is the in-place addition operator.
It's the same as doing cnt = cnt + 1
. For example:
>>> cnt = 0
>>> cnt += 2
>>> print cnt
2
>>> cnt += 42
>>> print cnt
44
The operator is often used in a similar fashion to the ++
operator in C-ish languages, to increment a variable by one in a loop (i += 1
)
There are similar operator for subtraction/multiplication/division/power and others:
i -= 1 # same as i = i - 1
i *= 2 # i = i * 2
i /= 3 # i = i / 3
i **= 4 # i = i ** 4
The +=
operator also works on strings, for example:
>>> s = "Hi"
>>> s += " there"
>>> print s
Hi there
People tend to recommend against doing this for performance reason, but for the most scripts this really isn't an issue. To quote from the "Sequence Types" docs:
- If s and t are both strings, some Python implementations such as CPython can usually perform an in-place optimization for assignments of the form s=s+t or s+=t. When applicable, this optimization makes quadratic run-time much less likely. This optimization is both version and implementation dependent. For performance sensitive code, it is preferable to use the str.join() method which assures consistent linear concatenation performance across versions and implementations.
The str.join() method refers to doing the following:
mysentence = []
for x in range(100):
mysentence.append("test")
" ".join(mysentence)
..instead of the more obvious:
mysentence = ""
for x in range(100):
mysentence += " test"
The problem with the later is (aside from the leading-space), depending on the Python implementation, the Python interpreter will have to make a new copy of the string in memory every time you append (because strings are immutable), which will get progressively slower the longer the string to append is.. Whereas appending to a list then joining it together into a string is a consistent speed (regardless of implementation)
If you're doing basic string manipulation, don't worry about it. If you see a loop which is basically just appending to a string, consider constructing an array, then "".join()
'ing it.
Try this command
load data local infile 'file.csv' into table table
fields terminated by ','
enclosed by '"'
lines terminated by '\n'
(column1, column2, column3,...)
The fields here are the actual table fields that the data needs to sit in. The enclosed by and lines terminated by are optional and can help if you have columns enclosed with double-quotes such as Excel exports, etc.
For further details check the manual.
For setting the first row as the table column names, just ignore the row from being read and add the values in the command.
If you want to make transparent background is gray, pls try:
.transparent{
background:rgba(1,1,1,0.5);
}
You can loop the array with a for loop and the object properties with for-in loops.
for (var i=0; i<result.length; i++)
for (var name in result[i]) {
console.log("Item name: "+name);
console.log("Source: "+result[i][name].sourceUuid);
console.log("Target: "+result[i][name].targetUuid);
}
keyPressed - when the key goes down
keyReleased - when the key comes up
keyTyped - when the unicode character represented by this key is sent by the keyboard to system input.
I personally would use keyReleased for this. It will fire only when they lift their finger up.
Note that keyTyped will only work for something that can be printed (I don't know if F5 can or not) and I believe will fire over and over again if the key is held down. This would be useful for something like... moving a character across the screen or something.
You can easily do this though,
df.apply(LabelEncoder().fit_transform)
EDIT2:
In scikit-learn 0.20, the recommended way is
OneHotEncoder().fit_transform(df)
as the OneHotEncoder now supports string input. Applying OneHotEncoder only to certain columns is possible with the ColumnTransformer.
EDIT3:
Since this answer is over a year ago, and generated many upvotes (including a bounty), I should probably extend this further.
For inverse_transform and transform, you have to do a little bit of hack.
from collections import defaultdict
d = defaultdict(LabelEncoder)
With this, you now retain all columns LabelEncoder
as dictionary.
# Encoding the variable
fit = df.apply(lambda x: d[x.name].fit_transform(x))
# Inverse the encoded
fit.apply(lambda x: d[x.name].inverse_transform(x))
# Using the dictionary to label future data
df.apply(lambda x: d[x.name].transform(x))
MOAR EDIT:
Using Neuraxle's FlattenForEach
step, it's possible to do this as well to use the same LabelEncoder
on all the flattened data at once:
FlattenForEach(LabelEncoder(), then_unflatten=True).fit_transform(df)
For using separate LabelEncoder
s depending for your columns of data, or if only some of your columns of data needs to be label-encoded and not others, then using a ColumnTransformer
is a solution that allows for more control on your column selection and your LabelEncoder instances.
Wrap an ArrayAdapter
around your List<ScanResult>
. Override getView()
to populate your rows with the ScanResult
data. Here is a free excerpt from one of my books that covers how to create custom ArrayAdapters
like this.
'1.0-0' will give you zero decimal places i.e. no decimals. e.g.$500
This can be confusing for anyone using nodejs for the first time. It is actually possible to pipe your node console output to the browser console. Take a look at connect-browser-logger on github
UPDATE: As pointed out by Yan, connect-browser-logger appears to be defunct. I would recommend NodeMonkey as detailed here : Output to Chrome console from Node.js
Windows Users need to set below paths:

The answer depends upon the degree of confidence you place in the data and how your data is being used. For example, if you're using it for mailing or shipping, you'll want to be be confident that the data is correct. If you're just using it as another fraud-prevention mechanism then you could potentially allow a degree of error to creep into the data.
If you want any degree of real accuracy, you're need to go with a service that does real address verification and you're going to have to pay for it. As has been mentioned by Adam, address verification and validation at first seems simple and easy, but it's a black hole fraught with challenges and, unless you've some underlying data to work with, virtually impossible to do by yourself. Trust me, you're actually saving money by using a service. You're welcome to go down this road yourself to experience what I mean, but I can guarantee you'll see the light, so to speak, after even a few hours (or days) of spinning your wheels.
I should mention that I'm the founder of SmartyStreets. We do address validation and verification addresses and we offer this for the USA and international as well. I'm more than happy to personally answer any questions you have on the topic of address cleansing, standardization, and validation.
Do you want to convert int
s to char
s?:
int yourInt = 33;
char ch = (char) yourInt;
System.out.println(yourInt);
System.out.println(ch);
// Output:
// 33
// !
Or do you want to convert int
s to String
s?
int yourInt = 33;
String str = String.valueOf(yourInt);
Or what is it that you mean?
Nowadays, you should use ERB::Util.url_encode
or CGI.escape
. The primary difference between them is their handling of spaces:
>> ERB::Util.url_encode("foo/bar? baz&")
=> "foo%2Fbar%3F%20baz%26"
>> CGI.escape("foo/bar? baz&")
=> "foo%2Fbar%3F+baz%26"
CGI.escape
follows the CGI/HTML forms spec and gives you an application/x-www-form-urlencoded
string, which requires spaces be escaped to +
, whereas ERB::Util.url_encode
follows RFC 3986, which requires them to be encoded as %20
.
See "What's the difference between URI.escape and CGI.escape?" for more discussion.
EDIT: This is quite old, and ugly, don't do this. You should use callbacks: https://stackoverflow.com/a/5316755/591257
EDIT 2: See the fetch API
Had same problem, solved it this way, using a global var. Not sure if it's the best but surely works. On error you get an empty string (myVar = ''), so you can handle that as needed.
var myVar = '';
function isSession(selector) {
$.ajax({
'type': 'POST',
'url': '/order.html',
'data': {
'issession': 1,
'selector': selector
},
'dataType': 'html',
'success': function(data) {
myVar = data;
},
'error': function() {
alert('Error occured');
}
});
return myVar;
}
mylist[c(5,7,9)]
should do it.
You want the sublists returned as sublists of the result list; you don't use [[]]
(or rather, the function is [[
) for that -- as Dason mentions in comments, [[
grabs the element.
In typescript it is possible to do an instanceof
check in an if statement and you will have access to the same variable with the Typed
properties.
So let's say MarkerSymbolInfo
has a property on it called marker
. You can do the following:
if (symbolInfo instanceof MarkerSymbol) {
// access .marker here
const marker = symbolInfo.marker
}
It's a nice little trick to get the instance of a variable using the same variable without needing to reassign it to a different variable name.

When we try to drop a column which is depended upon then we see this kind of error:
The object 'DF__*' is dependent on column ''.
drop the constraint which is dependent on that column with:
ALTER TABLE TableName DROP CONSTRAINT dependent_constraint;
Example:
Msg 5074, Level 16, State 1, Line 1
The object 'DF__Employees__Colf__1273C1CD' is dependent on column 'Colf'.
Msg 4922, Level 16, State 9, Line 1
ALTER TABLE DROP COLUMN Colf failed because one or more objects access this column.
Drop Constraint(DF__Employees__Colf__1273C1CD):
ALTER TABLE Employees DROP CONSTRAINT DF__Employees__Colf__1273C1CD;
Then you can Drop Column:
Alter Table TableName Drop column ColumnName
You could always use mysql's LOAD DATA
:
LOAD DATA LOCAL INFILE '/full/path/to/file/foo.csv' INTO TABLE `footable` FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'
to do bulk inserts rather than using a bunch of INSERT
statements.
For future readers, here is an elegant solution(5x5):
var matrix = [[Int]](repeating: [Int](repeating: 0, count: 5), count: 5)
and a dynamic approach:
var matrix = [[Int]]() // creates an empty matrix
var row = [Int]() // fill this row
matrix.append(row) // add this row
When you have a 6 digit color code e.g. #ffffff, replace it with #ffffff00. Just add 2 zeros at the end to make the color transparent.
Here is an article describing the new standard in more depth: https://css-tricks.com/8-digit-hex-codes/
All of the above answers are not match for Unicode characters in URL, for example: http://google.com?query=d?c+filan+dã+search
For the solution, this one should work:
(ftp:\/\/|www\.|https?:\/\/){1}[a-zA-Z0-9u00a1-\uffff0-]{2,}\.[a-zA-Z0-9u00a1-\uffff0-]{2,}(\S*)
$(function(){
var navMain = $("#your id");
navMain.on("click", "a", null, function () {
navMain.collapse('hide');
});
});
A Record lets you create a new type from a Union. The values in the Union are used as attributes of the new type.
For example, say I have a Union like this:
type CatNames = "miffy" | "boris" | "mordred";
Now I want to create an object that contains information about all the cats, I can create a new type using the values in the CatName Union as keys.
type CatList = Record<CatNames, {age: number}>
If I want to satisfy this CatList, I must create an object like this:
const cats:CatList = {
miffy: { age:99 },
boris: { age:16 },
mordred: { age:600 }
}
You get very strong type safety:
I used this recently to create a Status component. The component would receive a status prop, and then render an icon. I've simplified the code quite a lot here for illustrative purposes
I had a union like this:
type Statuses = "failed" | "complete";
I used this to create an object like this:
const icons: Record<
Statuses,
{ iconType: IconTypes; iconColor: IconColors }
> = {
failed: {
iconType: "warning",
iconColor: "red"
},
complete: {
iconType: "check",
iconColor: "green"
};
I could then render by destructuring an element from the object into props, like so:
const Status = ({status}) => <Icon {...icons[status]} />
If the Statuses union is later extended or changed, I know my Status component will fail to compile and I'll get an error that I can fix immediately. This allows me to add additional error states to the app.
Note that the actual app had dozens of error states that were referenced in multiple places, so this type safety was extremely useful.
I have noticed api example code contains an example of barchart with the value of the bar displayed on each bar:
"""

N = 5
men_means = (20, 35, 30, 35, 27)
men_std = (2, 3, 4, 1, 2)
ind = np.arange(N) # the x locations for the groups
width = 0.35 # the width of the bars
fig, ax = plt.subplots()
rects1 = ax.bar(ind, men_means, width, color='r', yerr=men_std)

You can also use the sqldf package in R.
Z <- sqldf('SELECT DISTINCT tablename.columnname FROM tablename ')
A solution similar to the one of @Nick G. by using filter, but make the parameter meaningful:
Implement an filter called relativedate
which calculate the date relative to current date by the given parameter as diff. As a result, (0 | relativedate)
means today and (1 | relativedate)
means tomorrow.
.filter('relativedate', ['$filter', function ($filter) {
return function (rel, format) {
let date = new Date();
date.setDate(date.getDate() + rel);
return $filter('date')(date, format || 'yyyy-MM-dd')
};
}]);
and your html:
<div ng-app="myApp">
<div>Yesterday: {{-1 | relativedate}}</div>
<div>Today: {{0 | relativedate}}</div>
<div>Tomorrow: {{1 | relativedate}}</div>
</div>
Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.
If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like
double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);
(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)
The best way to see the supported list is to start up the emulator in the latest version and open the "Custom Locale" app. This will list all of the supported languages and locales for that version of Android.
One solution that may helpful if you want to use the command line emulator cmder. You can install the package installer chocately. First we install chocately in windows command prompt using the following line:
@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"
refreshenv
After chocolatey is installed the choco command can be used to install make. Once installed, you will need add an alias to /cmder/config/user_aliases.cmd. The following line should be added:
make="path_to_chocolatey\chocolatey\bin\make.exe" $*
Make will then operate in the cmder environment.
jQuery provides a .text()
method that can be used in any browser. For example:
$('#myElement').text("Foo");
Here is an example of the practical significance of the difference and how it can bite you if you don't realize it (document.location being an object and document.location.href being a string):
We use MonoX Social CMS (http://mono-software.com) free version at http://social.ClipFlair.net and we wanted to add the language bar WebPart at some pages to localize them, but at some others (e.g. at discussions) we didn't want to use localization. So we made two master pages to use at all our .aspx (ASP.net) pages, in the first one we had the language bar WebPart and the other one had the following script to remove the /lng/el-GR etc. from the URLs and show the default (English in our case) language instead for those pages
<script>
var curAddr = document.location; //MISTAKE
var newAddr = curAddr.replace(new RegExp("/lng/[a-z]{2}-[A-Z]{2}", "gi"), "");
if (curAddr != newAddr)
document.location = newAddr;
</script>
But this code isn't working, replace function just returns Undefined (no exception thrown) so it tries to navigate to say x/lng/el-GR/undefined instead of going to url x. Checking it out with Mozilla Firefox's debugger (F12 key) and moving the cursor over the curAddr variable it was showing lots of info instead of some simple string value for the URL. Selecting Watch from that popup you could see in the watch pane it was writing "Location -> ..." instead of "..." for the url. That made me realize it was an object
One would have expected replace to throw an exception or something, but now that I think of it the problem was that it was trying to call some non-existent "replace" method on the URL object which seems to just give back "undefined" in Javascript.
The correct code in that case is:
<script>
var curAddr = document.location.href; //CORRECT
var newAddr = curAddr.replace(new RegExp("/lng/[a-z]{2}-[A-Z]{2}", "gi"), "");
if (curAddr != newAddr)
document.location = newAddr;
</script>
set -x
enables a mode of the shell where all executed commands are printed to the terminal. In your case it's clearly used for debugging, which is a typical use case for set -x
: printing every command as it is executed may help you to visualize the control flow of the script if it is not functioning as expected.
set +x
disables it.
Box and Cox (1964) suggested a family of transformations designed to reduce nonnormality of the errors in a linear model. In turns out that in doing this, it often reduces non-linearity as well.
Here is a nice summary of the original work and all the work that's been done since: http://www.ime.usp.br/~abe/lista/pdfm9cJKUmFZp.pdf
You will notice, however, that the log-likelihood function governing the selection of the lambda power transform is dependent on the residual sum of squares of an underlying model (no LaTeX on SO -- see the reference), so no transformation can be applied without a model.
A typical application is as follows:
library(MASS)
# generate some data
set.seed(1)
n <- 100
x <- runif(n, 1, 5)
y <- x^3 + rnorm(n)
# run a linear model
m <- lm(y ~ x)
# run the box-cox transformation
bc <- boxcox(y ~ x)
(lambda <- bc$x[which.max(bc$y)])
[1] 0.4242424
powerTransform <- function(y, lambda1, lambda2 = NULL, method = "boxcox") {
boxcoxTrans <- function(x, lam1, lam2 = NULL) {
# if we set lambda2 to zero, it becomes the one parameter transformation
lam2 <- ifelse(is.null(lam2), 0, lam2)
if (lam1 == 0L) {
log(y + lam2)
} else {
(((y + lam2)^lam1) - 1) / lam1
}
}
switch(method
, boxcox = boxcoxTrans(y, lambda1, lambda2)
, tukey = y^lambda1
)
}
# re-run with transformation
mnew <- lm(powerTransform(y, lambda) ~ x)
# QQ-plot
op <- par(pty = "s", mfrow = c(1, 2))
qqnorm(m$residuals); qqline(m$residuals)
qqnorm(mnew$residuals); qqline(mnew$residuals)
par(op)
As you can see this is no magic bullet -- only some data can be effectively transformed (usually a lambda less than -2 or greater than 2 is a sign you should not be using the method). As with any statistical method, use with caution before implementing.
To use the two parameter Box-Cox transformation, use the geoR
package to find the lambdas:
library("geoR")
bc2 <- boxcoxfit(x, y, lambda2 = TRUE)
lambda1 <- bc2$lambda[1]
lambda2 <- bc2$lambda[2]
EDITS: Conflation of Tukey and Box-Cox implementation as pointed out by @Yui-Shiuan fixed.
It sounds as if the only problem here is that the default editor that is launched is vi
or vim
, with which you're not familiar. (As quick tip, to exit that editor without saving changes, hit Esc a few times and then type :, q, ! and Enter.)
There are several ways to set up your default editor, and you haven't indicated which operating system you're using, so it's difficult to recommend one in particular. I'd suggest using:
git config --global core.editor "name-of-your-editor"
... which sets a global git preference for a particular editor. Alternatively you can set the $EDITOR
environment variable.
Realise this is pretty old now, but there's no need to manually write queries to a file like this. MySQL has logging support built in, you just need to enable it within your dev environment.
Take a look at the documentation for the 'general query log':
The Objective-C language level synchronization uses the mutex, just like NSLock
does. Semantically there are some small technical differences, but it is basically correct to think of them as two separate interfaces implemented on top of a common (more primitive) entity.
In particular with a NSLock
you have an explicit lock whereas with @synchronized
you have an implicit lock associated with the object you are using to synchronize. The benefit of the language level locking is the compiler understands it so it can deal with scoping issues, but mechanically they behave basically the same.
You can think of @synchronized
as a compiler rewrite:
- (NSString *)myString {
@synchronized(self) {
return [[myString retain] autorelease];
}
}
is transformed into:
- (NSString *)myString {
NSString *retval = nil;
pthread_mutex_t *self_mutex = LOOK_UP_MUTEX(self);
pthread_mutex_lock(self_mutex);
retval = [[myString retain] autorelease];
pthread_mutex_unlock(self_mutex);
return retval;
}
That is not exactly correct because the actual transform is more complex and uses recursive locks, but it should get the point across.
You don't need to explicitly use qualifiers like item.photo == ''
or item.photo != ''
. Like in JavaScript, an empty string will be evaluated as false.
Your views will be much cleaner and readable as well.
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0/angular.min.js"></script>_x000D_
<div ng-app init="item = {photo: ''}">_x000D_
<div ng-if="item.photo"> show if photo is not empty</div>_x000D_
<div ng-if="!item.photo"> show if photo is empty</div>_x000D_
_x000D_
<input type=text ng-model="item.photo" placeholder="photo" />_x000D_
</div
_x000D_
Updated to remove bug in Angular
Just wanted to add something: I found tim cooper's answer very useful, I used it to make a method which accepts an array of positions and does the insert on all of them so here that is:
EDIT: Looks like my old function assumed $insertstr
was only 1 character and that the array was sorted. This works for arbitrary character length.
function stringInsert($str, $pos, $insertstr) {
if (!is_array($pos)) {
$pos = array($pos);
} else {
asort($pos);
}
$insertionLength = strlen($insertstr);
$offset = 0;
foreach ($pos as $p) {
$str = substr($str, 0, $p + $offset) . $insertstr . substr($str, $p + $offset);
$offset += $insertionLength;
}
return $str;
}
Actually, I believe you want to use the __getattr__
special method instead.
Quote from the Python docs:
__getattr__( self, name)
Called when an attribute lookup has not found the attribute in the usual places (i.e. it is not an instance attribute nor is it found in the class tree for self). name is the attribute name. This method should return the (computed) attribute value or raise an AttributeError exception.
Note that if the attribute is found through the normal mechanism,__getattr__()
is not called. (This is an intentional asymmetry between__getattr__()
and__setattr__()
.) This is done both for efficiency reasons and because otherwise__setattr__()
would have no way to access other attributes of the instance. Note that at least for instance variables, you can fake total control by not inserting any values in the instance attribute dictionary (but instead inserting them in another object). See the__getattribute__()
method below for a way to actually get total control in new-style classes.
Note: for this to work, the instance should not have a test
attribute, so the line self.test=20
should be removed.

UPDATE t1
LEFT JOIN
t2
ON t2.id = t1.id
SET t1.col1 = newvalue
WHERE t2.id IS NULL
Note that for a SELECT
it would be more efficient to use NOT IN
/ NOT EXISTS
syntax:
SELECT t1.*
FROM t1
WHERE t1.id NOT IN
(
SELECT id
FROM t2
)
See the article in my blog for performance details:
LEFT JOIN
compared to NOT IN
Unfortunately, MySQL
does not allow using the target table in a subquery in an UPDATE
statement, that's why you'll need to stick to less efficient LEFT JOIN
syntax.
You can't import classes from the default package. You should avoid using the default package except for very small example programs.
From the Java language specification:
It is a compile time error to import a type from the unnamed package.
I had the similar issue. It happened every time when I run a pack of database (Spring JDBC) tests with SpringJUnit4ClassRunner
, so I resolved the issue putting @DirtiesContext
annotation for each test in order to cleanup the application context and release all resources thus each test could run with a new initalization of the application context.
You can use sprintf: http://php.net/manual/en/function.sprintf.php
<?php
$num = 4;
$num_padded = sprintf("%02d", $num);
echo $num_padded; // returns 04
?>
It will only add the zero if it's less than the required number of characters.
Edit: As pointed out by @FelipeAls:
When working with numbers, you should use %d
(rather than %s
), especially when there is the potential for negative numbers. If you're only using positive numbers, either option works fine.
For example:
sprintf("%04s", 10);
returns 0010
sprintf("%04s", -10);
returns 0-10
Where as:
sprintf("%04d", 10);
returns 0010
sprintf("%04d", -10);
returns -010
As you read through the examples below, just keep in mind this difference
true === true // true
"string" === true // false
1 === true // false
{} === true // false
But
Boolean("string") === true // true
Boolean(1) === true // true
Boolean({}) === true // true
Assertion passes when the statement passed to expect()
evaluates to true
expect(true).toBe(true) // pass
expect("123" === "123").toBe(true) // pass
In all other cases cases it would fail
expect("string").toBe(true) // fail
expect(1).toBe(true); // fail
expect({}).toBe(true) // fail
Even though all of these statements would evaluate to true
when doing Boolean()
:
So you can think of it as 'strict' comparison
This one does exactly the same type of comparison as .toBe(true)
, but was introduced in Jasmine recently in version 3.5.0
on Sep 20, 2019
toBeTruthy
on the other hand, evaluates the output of the statement into boolean first and then does comparison
expect(false).toBeTruthy() // fail
expect(null).toBeTruthy() // fail
expect(undefined).toBeTruthy() // fail
expect(NaN).toBeTruthy() // fail
expect("").toBeTruthy() // fail
expect(0).toBeTruthy() // fail
And IN ALL OTHER CASES it would pass, for example
expect("string").toBeTruthy() // pass
expect(1).toBeTruthy() // pass
expect({}).toBeTruthy() // pass
If your design can accommodate it, avoid local time conversion all together!
I know to some this might sound insane but think about UX: users process near, relative dates (today, yesterday, next Monday) faster than absolute dates (2010.09.17, Friday Sept 17) on glance. And when you think about it more, the accuracy of timezones (and DST) is more important the closer the date is to now()
, so if you can express dates/datetimes in a relative format for +/- 1 or 2 weeks, the rest of the dates can be UTC and it wont matter too much to 95% of users.
This way you can store all dates in UTC and do the relative comparisons in UTC and simply show the user UTC dates outside of your Relative Date Threshold.
This can also apply to user input too (but generally in a more limited fashion). Selecting from a drop down that only has { Yesterday, Today, Tomorrow, Next Monday, Next Thursday } is so much simpler and easier for the user than a date picker. Date pickers are some of the most pain inducing components of form filling. Of course this will not work for all cases but you can see that it only takes a little clever design to make it very powerful.

I have a 2010 iMac with 8GB of RAM, running Eclipse Neon.2 Release (4.6.2) with Java 1.8.0_25. With the VM argument -Xmx6g, I ran the following code:
StringBuilder sb = new StringBuilder();
for (int i = 0; i < Integer.MAX_VALUE; i++) {
try {
sb.append('a');
} catch (Throwable e) {
System.out.println(i);
break;
}
}
System.out.println(sb.toString().length());
This prints:
Requested array size exceeds VM limit
1207959550
So, it seems that the max array size is ~1,207,959,549. Then I realized that we don't actually care if Java runs out of memory: we're just looking for the maximum array size (which seems to be a constant defined somewhere). So:
for (int i = 0; i < 1_000; i++) {
try {
char[] array = new char[Integer.MAX_VALUE - i];
Arrays.fill(array, 'a');
String string = new String(array);
System.out.println(string.length());
} catch (Throwable e) {
System.out.println(e.getMessage());
System.out.println("Last: " + (Integer.MAX_VALUE - i));
System.out.println("Last: " + i);
}
}
Which prints:
Requested array size exceeds VM limit
Last: 2147483647
Last: 0
Requested array size exceeds VM limit
Last: 2147483646
Last: 1
Java heap space
Last: 2147483645
Last: 2
So, it seems the max is Integer.MAX_VALUE - 2, or (2^31) - 3
P.S. I'm not sure why my StringBuilder
maxed out at 1207959550
while my char[]
maxed out at (2^31)-3. It seems that AbstractStringBuilder
doubles the size of its internal char[]
to grow it, so that probably causes the issue.
Your regexp seems to validate both the file name and the extension. Is that what you need? I'll assume it's just the extension and would use a regexp like this:
\.(jpg|gif|doc|pdf)$
And set the matching to be case insensitive.
You can avoid the loop and cut etc by using:
awk -F ':' '{system("ping " $1);}' config.txt
However it would be better if you post a snippet of your config.txt
You have to read the API carefully for this methods. Sometimes you can get confused very easily.
It is either:
if (B.class.isInstance(view))
API says: Determines if the specified Object (the parameter) is assignment-compatible with the object represented by this Class (The class object you are calling the method at)
or:
if (B.class.isAssignableFrom(view.getClass()))
API says: Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter
or (without reflection and the recommended one):
if (view instanceof B)
I spent couple of hours with google and found the answer here
PUT => If user can update all or just a portion of the record, use PUT (user controls what gets updated)
PUT /users/123/email
[email protected]
PATCH => If user can only update a partial record, say just an email address (application controls what can be updated), use PATCH.
PATCH /users/123
[description of changes]
Why Patch
PUT
method need more bandwidth or handle full resources instead on partial. So PATCH
was introduced to reduce the bandwidth.
Explanation about PATCH
PATCH
is a method that is not safe, nor idempotent, and allows full and partial updates and side-effects on other resources.
PATCH
is a method which enclosed entity contains a set of instructions describing how a resource currently residing on the origin server should be modified to produce a new version.
PATCH /users/123
[
{ "op": "replace", "path": "/email", "value": "[email protected]" }
]

I solved the same error, by adding "zizaco/entrust": "*"
instead of the "zizaco/entrust": "~1.2"
.
Example for postgres:
string sql = "SELECT * FROM SomeTable WHERE id = ANY(@ids)"
var results = conn.Query(sql, new { ids = new[] { 1, 2, 3, 4, 5 }});
df.loc[:,'col':] = df.loc[:,'col':].apply(pd.to_numeric, errors = 'coerce')
Just want to add to Ben's answer on drop_duplicates:
keep
: {‘first’, ‘last’, False}, default ‘first’
first : Drop duplicates except for the first occurrence.
last : Drop duplicates except for the last occurrence.
False : Drop all duplicates.
So setting keep
to False will give you desired answer.
DataFrame.drop_duplicates(*args, **kwargs) Return DataFrame with duplicate rows removed, optionally only considering certain columns
Parameters: subset : column label or sequence of labels, optional Only consider certain columns for identifying duplicates, by default use all of the columns keep : {‘first’, ‘last’, False}, default ‘first’ first : Drop duplicates except for the first occurrence. last : Drop duplicates except for the last occurrence. False : Drop all duplicates. take_last : deprecated inplace : boolean, default False Whether to drop duplicates in place or to return a copy cols : kwargs only argument of subset [deprecated] Returns: deduplicated : DataFrame
As per bash - The Set Builtin manual, if -e
/errexit
is set, the shell exits immediately if a pipeline consisting of a single simple command, a list or a compound command returns a non-zero status.
By default, the exit status of a pipeline is the exit status of the last command in the pipeline, unless the pipefail
option is enabled (it's disabled by default).
If so, the pipeline's return status of the last (rightmost) command to exit with a non-zero status, or zero if all commands exit successfully.
If you'd like to execute something on exit, try defining trap
, for example:
trap onexit EXIT
where onexit
is your function to do something on exit, like below which is printing the simple stack trace:
onexit(){ while caller $((n++)); do :; done; }
There is similar option -E
/errtrace
which would trap on ERR instead, e.g.:
trap onerr ERR
Zero status example:
$ true; echo $?
0
Non-zero status example:
$ false; echo $?
1
Negating status examples:
$ ! false; echo $?
0
$ false || true; echo $?
0
Test with pipefail
being disabled:
$ bash -c 'set +o pipefail -e; true | true | true; echo success'; echo $?
success
0
$ bash -c 'set +o pipefail -e; false | false | true; echo success'; echo $?
success
0
$ bash -c 'set +o pipefail -e; true | true | false; echo success'; echo $?
1
Test with pipefail
being enabled:
$ bash -c 'set -o pipefail -e; true | false | true; echo success'; echo $?
