I had to sort on several criterion (date, and, if same date; other things...). What was working on Eclipse with an older version of Java, did not worked any more on Android : comparison method violates contract ...
After reading on StackOverflow, I wrote a separate function that I called from compare() if the dates are the same. This function calculates the priority, according to the criteria, and returns -1, 0, or 1 to compare(). It seems to work now.
I have found a way to do this that it requires 2 steps, but it works
' to copy out a filtered selection into a different sheet
number_of_dinosaurs = WorksheetFunction.Count(Worksheets("Dinosaurs").Range("A2", "A3000"))
With Worksheets("Dinosaurs")
.AutoFilterMode = False
With .Range("$A$4:$E$" & number_of_dinosaurs)
.AutoFilter Field:=2, Criteria1:="*teeth*" ' change your criteria to whatever you like
.SpecialCells(xlCellTypeVisible).Copy Destination:=Worksheets("Bad_Dinosaurs").Range("A1")

' then do a normal count on the secondary sheet

I've used encodeURIComponent() and decodeURIComponent() too.
Try
\d \w |\d
or add a positive lookahead if you don't want to include the trailing space in the match
\d \w(?= )|\d
When you have two alternatives where one is an extension of the other, put the longer one first, otherwise it will have no opportunity to be matched.
problem solved for me. I changed version from pytorch=1.5.1 to pytorch=1.4 and typed the below command in anaconda prompt window
conda install pytorch==1.4.0 torchvision==0.5.0 -c pytorch
None of the above helped for me.

Suppose you need only x:target/classes in your classpath. Then you just add this folder to your classpath and %IDEA%\lib\idea_rt.jar. Now it will work. That's it.
With respect to William Brendel's posts and dbconfessions question, regarding case 2. Here is an example:
public class Window {
private Window parent;
public Window (Window parent) {
this.parent = parent;
}
public void addSubWindow() {
Window child = new Window(this);
list.add(child);
}
public void printInfo() {
if (parent == null) {
System.out.println("root");
} else {
System.out.println("child");
}
}
}
I've seen this used, when building parent-child relation's with objects. However, please note that it is simplified for the sake of brevity.
Adding to @Kirill Fuchs excellent solution and answering @StackUser's doubt - while starting the http-server, set the path till the app folder only, NOT till the html page!
http-server C:\location\to\app
and access index.html

folder
Here's a simplest example from ASP.NET Community, this gave me a clear understanding on the concept....
what difference does this make?
For an example of this, here is a way to put focus on a text box on a page when the page is loaded into the browser—with Visual Basic using the RegisterStartupScript
method:
Page.ClientScript.RegisterStartupScript(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)
This works well because the textbox on the page is generated and placed on the page by the time the browser gets down to the bottom of the page and gets to this little bit of JavaScript.
But, if instead it was written like this (using the RegisterClientScriptBlock
method):
Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)
Focus will not get to the textbox control and a JavaScript error will be generated on the page
The reason for this is that the browser will encounter the JavaScript before the text box is on the page. Therefore, the JavaScript will not be able to find a TextBox1.
I've got the same error. I have been trying to fixing this by setting higher permission to account running SQL Client service, however it didnt help. The problem was that I run MS Sql Management studio just within my account. So, next time... assure that you are running it as Run as Administrator, if using Win7 with UAC enabled.
There are two type of paths: absolute and relative. This is basically the same for files in your hard disc and directories in a URL.
Absolute paths start with a leading slash. They always point to the same location, no matter where you use them:
/pages/en/faqs/faq-page1.html
Relative paths are the rest (all that do not start with slash). The location they point to depends on where you are using them
index.html
is:
/pages/en/faqs/index.html
if called from /pages/en/faqs/faq-page1.html
/pages/index.html
if called from /pages/example.html
There are also two special directory names: .
and ..
:
.
means "current directory"..
means "parent directory"You can use them to build relative paths:
../index.html
is /pages/en/index.html
if called from /pages/en/faqs/faq-page1.html
../../index.html
is /pages/index.html
if called from /pages/en/faqs/faq-page1.html
Once you're familiar with the terms, it's easy to understand what it's failing and how to fix it. You have two options:
If you're using d3 for handling multiple objects with the same class / id
You can remove a subset of class elements by using d3.selectAll(".classname");
For example the donut graph here on http://medcorp.co.nz utilizes copies of an arc object with class name "arc" and there's a single line of d3, d3.selectAll(".arc").remove(); to remove all those objects;
using document.getElementById("arc").remove(); only removes a single element and would have to be called multiple times (as is with the suggestions above he creates a loop to remove the objects n times)
Have you recently changed your MySQL Server root password? If answer is YES, than this is the cause of the error / warning inside phpMyAdmin console. To fix the problem, simply edit your phpMyAdmin’s config-db.php file and setup the proper database password.
First answer is messing too much in my view and second answer did not work for me. So:
In Linux-based servers the file is usually located in:
/etc/phpmyadmin/config-db.php
or:
/etc/phpMyAdmin/config-db.php
Example: (My File looked like this and I changed the user fromphpmyadmin
to admin
, the username I created for maintaining my database through phpmyadmin, and put in the appropriate password.
$dbuser='phpmyadmin';
$dbpass=''; // set current password between quotes ' '
$basepath='';
$dbname='phpmyadmin';
$dbserver='';
$dbport='';
$dbtype='mysql';
strftime
(C89)
Martin mentioned it, here's an example:
main.c
#include <assert.h>
#include <stdio.h>
#include <time.h>
int main(void) {
time_t t = time(NULL);
struct tm *tm = localtime(&t);
char s[64];
assert(strftime(s, sizeof(s), "%c", tm));
printf("%s\n", s);
return 0;
}
Compile and run:
gcc -std=c89 -Wall -Wextra -pedantic -o main.out main.c
./main.out
Sample output:
Thu Apr 14 22:39:03 2016
The %c
specifier produces the same format as ctime
.
One advantage of this function is that it returns the number of bytes written, allowing for better error control in case the generated string is too long:
RETURN VALUE
Provided that the result string, including the terminating null byte, does not exceed max bytes, strftime() returns the number of bytes (excluding the terminating null byte) placed in the array s. If the length of the result string (including the terminating null byte) would exceed max bytes, then
strftime() returns 0, and the contents of the array are undefined.
Note that the return value 0 does not necessarily indicate an error. For example, in many locales %p yields an empty string. An empty format string will likewise yield an empty string.
asctime
and ctime
(C89, deprecated in POSIX 7)
asctime
is a convenient way to format a struct tm
:
main.c
#include <stdio.h>
#include <time.h>
int main(void) {
time_t t = time(NULL);
struct tm *tm = localtime(&t);
printf("%s", asctime(tm));
return 0;
}
Sample output:
Wed Jun 10 16:10:32 2015
And there is also ctime()
which the standard says is a shortcut for:
asctime(localtime())
As mentioned by Jonathan Leffler, the format has the shortcoming of not having timezone information.
POSIX 7 marked those functions as "obsolescent" so they could be removed in future versions:
The standard developers decided to mark the asctime() and asctime_r() functions obsolescent even though asctime() is in the ISO C standard due to the possibility of buffer overflow. The ISO C standard also provides the strftime() function which can be used to avoid these problems.

Easiest way do this is to remove filter, fill series from top of total data. Filter your desired data back in, copy list of numbers into a new sheet (this should be only the total lines you want to add numbering to) paste into column A1. Add "1" into column B1, right click and hold then drag down to end of numbers and choose "fill series". Now return to your list with filters and in the next column to the right "VLOOKUP" the filtered number against the list you pasted into a new sheet and return the 2nd value.

Quick Update, effective from February 15th, 2015, we cannot submit apps to the store that were developed using an SDK prior to iOS 8. So, keeping that in mind , its better to not to worry about this issue as many people have suggested that apps made in Swift can be deployed to OS X 10.9 and iOS 7.0 as well.
If you are using wampserver 3 (recommended, works with no configuration usually)
if this doesnt fix it, try:
right click wampserver icon > Tools > Check httpd.conf syntax (then fix the issue it identifies and restart all services, likely it's bad syntax in your virtual hosts file)
right click wampserver icon > Tools > test port 80 (you likely have skype turned on or something else, turn it off and restart all services)

I'd prefer to normalize your table structure more, something like;
COMMENTS
-------
id (pk)
title
comment
userId
USERS
-----
id (pk)
name
email
COMMENT_VOTE
------------
commentId (pk)
userId (pk)
rating (float)
Now it's easier to maintain! And MySQL only accept one vote per user and comment.
To answer "why" someone might use it, I was tempted to use it since I had the $_POST values stored after the page refresh or while going from one page to another. My sense tells me this is not a good practice, but it works nevertheless.
Or you can simply start the activity as shown below;
startActivity( new Intent(currentactivity.this, Tostartactivity.class));
If you are only comparing objects of the same type or further down the inheritance chain, why not specify the parameter as your base type, rather than object ?
Also do null checks on the parameter as well.
Furthermore I'd make use of 'var' just to make the code more readable (if its c#3 code)
Also, if the object has reference types as properties then you are just calling ToString() on them which doesn't really compare values. If ToString isn't overwridden then its just going to return the type name as a string which could return false-positives.
There is no documented LEFT() function in Oracle. Find the full set here.
Probably what you have is a user-defined function. You can check that easily enough by querying the data dictionary:
select * from all_objects
where object_name = 'LEFT'
But there is the question of why the stored procedure works and the query doesn't. One possible solution is that the stored procedure is owned by another schema, which also owns the LEFT() function. They have granted rights on the procedure but not its dependencies. This works because stored procedures run with DEFINER privileges by default, so you run the stored procedure as if you were its owner.
If this is so then the data dictionary query I listed above won't help you: it will only return rows for objects you have rights on. In which case you will need to run the query as the stored procedure's owner or connect as a user with the rights to query DBA_OBJECTS instead.
Oracle Setup:
CREATE OR REPLACE FUNCTION split_String(
i_str IN VARCHAR2,
i_delim IN VARCHAR2 DEFAULT ','
) RETURN SYS.ODCIVARCHAR2LIST DETERMINISTIC
AS
p_result SYS.ODCIVARCHAR2LIST := SYS.ODCIVARCHAR2LIST();
p_start NUMBER(5) := 1;
p_end NUMBER(5);
c_len CONSTANT NUMBER(5) := LENGTH( i_str );
c_ld CONSTANT NUMBER(5) := LENGTH( i_delim );
BEGIN
IF c_len > 0 THEN
p_end := INSTR( i_str, i_delim, p_start );
WHILE p_end > 0 LOOP
p_result.EXTEND;
p_result( p_result.COUNT ) := SUBSTR( i_str, p_start, p_end - p_start );
p_start := p_end + c_ld;
p_end := INSTR( i_str, i_delim, p_start );
END LOOP;
IF p_start <= c_len + 1 THEN
p_result.EXTEND;
p_result( p_result.COUNT ) := SUBSTR( i_str, p_start, c_len - p_start + 1 );
END IF;
END IF;
RETURN p_result;
END;

I would use a list:
string = []
for i in range(0, 9):
string.append("Hello")
This way, you would have 9 "Hello" and you could get them individually like this:
string[x]
Where x
would identify which "Hello" you want.
So, print(string[1])
would print Hello
.
This is how I've implemented this in my project.
function array_map_associative(callable $callback, $array) {
/* map original array keys, and call $callable with $key and value of $key from original array. */
return array_map(function($key) use ($callback, $array){
return $callback($key, $array[$key]);
}, array_keys($array));
}
Try this:
var setCanvasSize = function() {
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
}
Access requires parentheses in the FROM
clause for queries which include more than one join. Try it this way ...
FROM
((tbl_employee
INNER JOIN tbl_netpay
ON tbl_employee.emp_id = tbl_netpay.emp_id)
INNER JOIN tbl_gross
ON tbl_employee.emp_id = tbl_gross.emp_ID)
INNER JOIN tbl_tax
ON tbl_employee.emp_id = tbl_tax.emp_ID;
If possible, use the Access query designer to set up your joins. The designer will add parentheses as required to keep the db engine happy.
What about:
@echo off
set myvar="the list: "
for /r %%i in (*.doc) DO call :concat %%i
echo %myvar%
goto :eof
:concat
set myvar=%myvar% %1;
goto :eof
Its not possible thats the whole point of hashing. You can however bruteforce by going through all possibilities (using all possible digits characters in every possible order) and hashing them and checking for a collision.
for more information on hashing and MD5 etc see: http://en.wikipedia.org/wiki/MD5 , http://en.wikipedia.org/wiki/Hash_function , http://en.wikipedia.org/wiki/Cryptographic_hash_function and http://onin.com/hhh/hhhexpl.html

Using the angular.module API with an array at the end will tell angular to create a new module:
myApp.js
// It is like saying "create a new module"
angular.module('myApp.controllers', []); // Notice the empty array at the end here
Using it without the array is actually a getter function. So to seperate your controllers, you can do:
Ctrl1.js
// It is just like saying "get this module and create a controller"
angular.module('myApp.controllers').controller('Ctrlr1', ['$scope', '$http', function($scope, $http) {}]);
Ctrl2.js
angular.module('myApp.controllers').controller('Ctrlr2', ['$scope', '$http', function($scope, $http) {}]);
During your javascript imports, just make sure myApp.js is after AngularJS but before any controllers / services / etc...otherwise angular won't be able to initialize your controllers.
Sometimes this error happens because of unexpected CR characters in file, usually because the file was generated on a Windows system which uses CR line endings. You can fix this by running os2unix
or tr
, for example:
tr -d '\015' < yourscript.sh > newscript.sh
This removes any CR characters from the file.
And a key point - although TRUNCATE TABLE seems like a DELETE with no WHERE clause, TRUNCATE is not DML, it is DDL. DELETE requires a COMMIT, but TRUNCATE does not.
If you want to retrieve the length (and possibly all other metadata) from your media file with ffmpeg by using a python script you could try this:
import subprocess
import json
input_file = "< path to your input file here >"
metadata = subprocess.check_output(f"ffprobe -i {input_file} -v quiet -print_format json -show_format -hide_banner".split(" "))
metadata = json.loads(metadata)
print(f"Length of file is: {float(metadata['format']['duration'])}")
print(metadata)
Output:
Length of file is: 7579.977143

maybe you need to grant more permissions to your files.
suppose your code are under /var/www/my_project
try chmod -R 777 /var/www/my_project
To default-initialize an array of T
s, T
must be default constructible. Normally the compiler gives you a default constructor for free. However, since you declared a constructor yourself, the compiler does not generate a default constructor.
Your options:
initialize all the elements of the array upon declaration (you can do this because name
is an aggregate);
name someName[4] = { { "Arthur", "Dent" },
{ "Ford", "Prefect" },
{ "Tricia", "McMillan" },
{ "Zaphod", "Beeblebrox" }
};
use a std::vector
instead, and only add element when you have them constructed.
There's always the string functions, if you know you're always going to remove the fourth character:
str.slice(0, 4) + str.slice(5, str.length))
Step 1.
Stop MySQL server
Step 2.
add this line to my.cnf ( In windows it is called my.ini )
set-variable=innodb_force_recovery=6
Step 3.
delete ib_logfile0 and ib_logfile1
Step 4.
Start MySQL server
Step 5.
Run this command:
mysqlcheck --database db_name table_name -uroot -p
After you have successfully fixed the crashed innodb table, don't forget to remove #set-variable=innodb_force_recovery=6 from my.cnf and then restart MySQL server again.
Here's what I did to fix this:
1) Create a new project
2) open the gradle-wrapper.properties file and copy the distributionUrl to your project e.g.:
distributionUrl=https\://services.gradle.org/distributions/gradle-3.2-all.zip
3) open the build.gradle (Project) and copy the gradle dependency to your project e.g.:
classpath 'com.android.tools.build:gradle:2.3.0-beta1'
4) File --> Invalidate Caches / Restart (I think a re-sync may have sufficed, but didn't try it)
5) Delete that project you made (optional)
Look, this is a silly way to do things, but Android Studio is free so who am I to complain...
Just as an FYI, here is my working code:
src_dir = "C:\\temp\\CSV\\"
target_dir = "C:\\temp\\output2\\"
keyword = "KEYWORD"
for f in os.listdir(src_dir):
file_name = os.path.join(src_dir, f)
out_file = os.path.join(target_dir, f)
with open(file_name, "r+") as fi, open(out_file, "w") as fo:
for line in fi:
if keyword not in line:
fo.write(line)
Thanks again to everyone for all the great feedback!
Take a character pointer to store required string.If you have some idea about possible size of string then use function
char *fgets (char *str, int size, FILE* file);`
else you can allocate memory on runtime too using malloc() function which dynamically provides requested memory.
java -verbose:class HelloWorld
might help you understand which classes are being loaded.
Also, as mentioned before, remember to call the full qualified name (i.e. include package).
Try adding this to your dependencies:
compile 'org.apache.httpcomponents:httpclient:4.4-alpha1'
And generally if you want to use a library and you are searching for the Gradle dependency line you can use Gradle Please
EDIT: Check this one too.
you need /q at the end
MsiExec.exe /x {2F808931-D235-4FC7-90CD-F8A890C97B2F} /q
You can also quite easily use pdfminer as a library. You have access to the pdf's content model, and can create your own text extraction. I did this to convert pdf contents to semi-colon separated text, using the code below.
The function simply sorts the TextItem content objects according to their y and x coordinates, and outputs items with the same y coordinate as one text line, separating the objects on the same line with ';' characters.
Using this approach, I was able to extract text from a pdf that no other tool was able to extract content suitable for further parsing from. Other tools I tried include pdftotext, ps2ascii and the online tool pdftextonline.com.
pdfminer is an invaluable tool for pdf-scraping.
def pdf_to_csv(filename):
from pdflib.page import TextItem, TextConverter
from pdflib.pdfparser import PDFDocument, PDFParser
from pdflib.pdfinterp import PDFResourceManager, PDFPageInterpreter
class CsvConverter(TextConverter):
def __init__(self, *args, **kwargs):
TextConverter.__init__(self, *args, **kwargs)
def end_page(self, i):
from collections import defaultdict
lines = defaultdict(lambda : {})
for child in self.cur_item.objs:
if isinstance(child, TextItem):
(_,_,x,y) = child.bbox
line = lines[int(-y)]
line[x] = child.text
for y in sorted(lines.keys()):
line = lines[y]
self.outfp.write(";".join(line[x] for x in sorted(line.keys())))
self.outfp.write("\n")
# ... the following part of the code is a remix of the
# convert() function in the pdfminer/tools/pdf2text module
rsrc = PDFResourceManager()
outfp = StringIO()
device = CsvConverter(rsrc, outfp, "ascii")
doc = PDFDocument()
fp = open(filename, 'rb')
parser = PDFParser(doc, fp)
doc.initialize('')
interpreter = PDFPageInterpreter(rsrc, device)
for i, page in enumerate(doc.get_pages()):
outfp.write("START PAGE %d\n" % i)
interpreter.process_page(page)
outfp.write("END PAGE %d\n" % i)
device.close()
fp.close()
return outfp.getvalue()
UPDATE:
The code above is written against an old version of the API, see my comment below.
If you want to modify the original array instead of returning a new array, use .push()
...
array1.push.apply(array1, array2);
array1.push.apply(array1, array3);
I used .apply
to push the individual members of arrays 2
and 3
at once.
or...
array1.push.apply(array1, array2.concat(array3));
To deal with large arrays, you can do this in batches.
for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
array1.push.apply(array1, to_add.slice(n, n+300));
}
If you do this a lot, create a method or function to handle it.
var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);
Object.defineProperty(Array.prototype, "pushArrayMembers", {
value: function() {
for (var i = 0; i < arguments.length; i++) {
var to_add = arguments[i];
for (var n = 0; n < to_add.length; n+=300) {
push_apply(this, slice_call(to_add, n, n+300));
}
}
}
});
and use it like this:
array1.pushArrayMembers(array2, array3);
var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_
_x000D_
Object.defineProperty(Array.prototype, "pushArrayMembers", {_x000D_
value: function() {_x000D_
for (var i = 0; i < arguments.length; i++) {_x000D_
var to_add = arguments[i];_x000D_
for (var n = 0; n < to_add.length; n+=300) {_x000D_
push_apply(this, slice_call(to_add, n, n+300));_x000D_
}_x000D_
}_x000D_
}_x000D_
});_x000D_
_x000D_
var array1 = ['a','b','c'];_x000D_
var array2 = ['d','e','f'];_x000D_
var array3 = ['g','h','i'];_x000D_
_x000D_
array1.pushArrayMembers(array2, array3);_x000D_
_x000D_
document.body.textContent = JSON.stringify(array1, null, 4);

That's it!
I have spent 2h on finding out why EADDRINUSE
wasn't allowing me to sart an app (other node-express servers were ok)... it started working after adding
lazyConnect: true,
to datasource configuration.
Don't ask me why it helped. I do not know. I am putting this info here just for people having the same issue.
Change your jQuery code with this. It will alert the id of the a.
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
markActiveLink();
alert('123');
});
function markActiveLink(el) {
var el = $('a').attr("id")
alert(el);
}
You can try this: https://github.com/msqrt/shader-printf which is an implementation called appropriately "Simple printf functionality for GLSL."
You might also want to try ShaderToy, and maybe watch a video like this one (https://youtu.be/EBrAdahFtuo) from "The Art of Code" YouTube channel where you can see some of the techniques that work well for debugging and visualising. I can strongly recommend his channel as he writes some really good stuff and he also has a knack for presenting complex ideas in novel, highly engaging and and easy to digest formats (His Mandelbrot video is a superb example of exactly that : https://youtu.be/6IWXkV82oyY)
I hope nobody minds this late reply, but the question ranks high on Google searches for GLSL debugging and much has of course changed in 9 years :-)
PS: Other alternatives could also be NVIDIA nSight and AMD ShaderAnalyzer which offer a full stepping debugger for shaders.
To print off_t
:
printf("%jd\n", (intmax_t)x);
To print size_t
:
printf("%zu\n", x);
To print ssize_t
:
printf("%zd\n", x);
See 7.19.6.1/7 in the C99 standard, or the more convenient POSIX documentation of formatting codes:
http://pubs.opengroup.org/onlinepubs/009695399/functions/fprintf.html
If your implementation doesn't support those formatting codes (for example because you're on C89), then you have a bit of a problem since AFAIK there aren't integer types in C89 that have formatting codes and are guaranteed to be as big as these types. So you need to do something implementation-specific.
For example if your compiler has long long
and your standard library supports %lld
, you can confidently expect that will serve in place of intmax_t
. But if it doesn't, you'll have to fall back to long
, which would fail on some other implementations because it's too small.

I was having this issue and nothing worked. I ran xcode-select --install
and also installed /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
.
BACKGROUND
Since I was having issues with App Store on a new laptop, I was forced to download the Xcode Beta installer from the Apple website to install Xcode outside App Store. So I only had Xcode Beta installed.
SOLUTION
This, (I think), was making clang
to not find the SDKROOT
directory /Applications/Xcode.app/....
, because there is no Beta
in the path, or maybe Xcode Beta simply doesn't install it (I don't know).
To fix the issue, I had to remove Xcode Beta and resolve the App Store issue to install the release version.
tldr;
If you have Xcode Beta, try cleaning up everything and installing the release version before trying out the solutions that are working for other people.
In your project, find Target -> Build Settings -> Other Linker Flags
, select Other Linker Flags
, press delete
(Mac Keyboard)/Backspace
(Normal keyboard) to recover the setting. It works for me.
Example:
Before
After
var arrofobject = [{"id":"197","category":"Damskie"},{"id":"198","category":"M\u0119skie"}];_x000D_
var data = arrofobject.map(arrofobject => arrofobject);_x000D_
console.log(data)
_x000D_
for more details please look at jQuery.map()
Maybe you are looking for Vector
. It's capacity is automatically expanded if needed. It's not the best choice but will do in simple situations. It's worth your time to read up on ArrayList
instead.
This will do:
▢
It is ?
(known as a "WHITE SQUARE WITH ROUNDED CORNERS" on fileformat.info)
Or
◻
as ?
(known as a "WHITE MEDIUM SQUARE" on the same website)
Two with shadow:
❏
❑
as ? and ? . The difference between them is the shadows' shape. You can see it if you zoom in or if you print it out. (They are known as "LOWER RIGHT DROP-SHADOWED WHITE SQUARE" and "LOWER RIGHT SHADOWED WHITE SQUARE", respectively).
You can also use
☐
which is ?
(known as a "BALLOT BOX").
A sample is at http://jsfiddle.net/S2QCt/267/
(a note: on the Mac, ▢
is quite nice, because it is bigger and somewhat more elegant than ☐
On Windows, ☐
looks more standard, while ▢
is somewhat small.)

If you are using Firefox or a Browser it cannot be done with most of these Console methods once you have started an iterator ( as you can see I have ). You can go to source and manually pause the execution of the script. ( This still does not Stop it completely per say)
I caught this error a few days ago.
IN my case it was because I was using a Transaction on a Singleton.
.Net does not work well with Singleton as stated above.
My solution was this:
public class DbHelper : DbHelperCore
{
public DbHelper()
{
Connection = null;
Transaction = null;
}
public static DbHelper instance
{
get
{
if (HttpContext.Current is null)
return new DbHelper();
else if (HttpContext.Current.Items["dbh"] == null)
HttpContext.Current.Items["dbh"] = new DbHelper();
return (DbHelper)HttpContext.Current.Items["dbh"];
}
}
public override void BeginTransaction()
{
Connection = new SqlConnection(Entity.Connection.getCon);
if (Connection.State == System.Data.ConnectionState.Closed)
Connection.Open();
Transaction = Connection.BeginTransaction();
}
}
I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class
You can always add your own AssemblyInfo.cs, which comes in handy for InternalsVisibleToAttribute
, CLSCompliantAttribute
and others that are not automatically generated.
<project name> > Add > New Folder
. Add > New Item...
.If you want to move your attributes back to AssemblyInfo.cs instead of having them auto-generated, you can suppress them in MSBuild as natemcmaster pointed out in his answer.
I've designed and implemented Dollar for this kind of tasks:
String[] strarray= $(strlist).toArray();
With re-encoding:
ffmpeg -y -i seeing_noaudio.mp4 -vf "setpts=1.25*PTS" -r 24 seeing.mp4
Without re-encoding:
First step - extract video to raw bitstream
ffmpeg -y -i seeing_noaudio.mp4 -c copy -f h264 seeing_noaudio.h264
Remux with new framerate
ffmpeg -y -r 24 -i seeing_noaudio.h264 -c copy seeing.mp4
By definition dictionaries are unordered, and therefore cannot be indexed. For that kind of functionality use an ordered dictionary. Python Ordered Dictionary
To simplify Kirubaharan's answer a bit:
df['Datetime'] = pd.to_datetime(df['date'] + ' ' + df['time'])
df = df.set_index('Datetime')
And to get rid of unwanted columns (as OP did but did not specify per se in the question):
df = df.drop(['date','time'], axis=1)
Give a style inside the td element or in your scss file, like this:
vertical-align:
middle;
While the other answers and the accepted one are correct and should be followed in real code, just for completeness and humor, you can try the fuckitpy
( https://github.com/ajalt/fuckitpy ) module.
Your code can be changed to the following:
@fuckitpy
def myfunc():
do_smth1()
do_smth2()
Then calling myfunc()
would call do_smth2()
even if there is an exception in do_smth1())
Note: Please do not try it in any real code, it is blasphemy
jQuery 1.5 added deferred objects that handle this nicely. Simply call $.post
and attach any handlers you'd like after the call. Deferred objects even allow you to attach multiple success and error handlers.
Example:
$.post('status.ajax.php', {deviceId: id})
.done( function(msg) { ... } )
.fail( function(xhr, textStatus, errorThrown) {
alert(xhr.responseText);
});
Prior to jQuery 1.8, the function done
was called success
and fail
was called error
.
There's probably a another way or better. But this is how I do this in Spring Boot.
My property file contains the following lines. "," is the delimiter in each line.
mml.pots=STDEP:DETY=LI3;,STDEP:DETY=LIMA;
mml.isdn.grunntengingar=STDEP:DETY=LIBAE;,STDEP:DETY=LIBAMA;
mml.isdn.stofntengingar=STDEP:DETY=LIPRAE;,STDEP:DETY=LIPRAM;,STDEP:DETY=LIPRAGS;,STDEP:DETY=LIPRVGS;
My server config
@Configuration
public class ServerConfig {
@Inject
private Environment env;
@Bean
public MMLProperties mmlProperties() {
MMLProperties properties = new MMLProperties();
properties.setMmmlPots(env.getProperty("mml.pots"));
properties.setMmmlPots(env.getProperty("mml.isdn.grunntengingar"));
properties.setMmmlPots(env.getProperty("mml.isdn.stofntengingar"));
return properties;
}
}
MMLProperties class.
public class MMLProperties {
private String mmlPots;
private String mmlIsdnGrunntengingar;
private String mmlIsdnStofntengingar;
public MMLProperties() {
super();
}
public void setMmmlPots(String mmlPots) {
this.mmlPots = mmlPots;
}
public void setMmlIsdnGrunntengingar(String mmlIsdnGrunntengingar) {
this.mmlIsdnGrunntengingar = mmlIsdnGrunntengingar;
}
public void setMmlIsdnStofntengingar(String mmlIsdnStofntengingar) {
this.mmlIsdnStofntengingar = mmlIsdnStofntengingar;
}
// These three public getXXX functions then take care of spliting the properties into List
public List<String> getMmmlCommandForPotsAsList() {
return getPropertieAsList(mmlPots);
}
public List<String> getMmlCommandsForIsdnGrunntengingarAsList() {
return getPropertieAsList(mmlIsdnGrunntengingar);
}
public List<String> getMmlCommandsForIsdnStofntengingarAsList() {
return getPropertieAsList(mmlIsdnStofntengingar);
}
private List<String> getPropertieAsList(String propertie) {
return ((propertie != null) || (propertie.length() > 0))
? Arrays.asList(propertie.split("\\s*,\\s*"))
: Collections.emptyList();
}
}
Then in my Runner class I Autowire MMLProperties
@Component
public class Runner implements CommandLineRunner {
@Autowired
MMLProperties mmlProperties;
@Override
public void run(String... arg0) throws Exception {
// Now I can call my getXXX function to retrieve the properties as List
for (String command : mmlProperties.getMmmlCommandForPotsAsList()) {
System.out.println(command);
}
}
}
Hope this helps
Obviously there is no periodic checking of Scope
whether there is any change in the Objects attached to it. Not all the objects attached to scope are watched . Scope prototypically maintains a $$watchers . Scope
only iterates through this $$watchers
when $digest
is called .
Angular adds a watcher to the $$watchers for each of these
- {{expression}} — In your templates (and anywhere else where there’s an expression) or when we define ng-model.
- $scope.$watch(‘expression/function’) — In your JavaScript we can just attach a scope object for angular to watch.
$watch function takes in three parameters:
First one is a watcher function which just returns the object or we can just add an expression.
Second one is a listener function which will be called when there is a change in the object. All the things like DOM changes will be implemented in this function.
The third being an optional parameter which takes in a boolean . If its true , angular deep watches the object & if its false Angular just does a reference watching on the object. Rough Implementation of $watch looks like this
Scope.prototype.$watch = function(watchFn, listenerFn) {
var watcher = {
watchFn: watchFn,
listenerFn: listenerFn || function() { },
last: initWatchVal // initWatchVal is typically undefined
};
this.$$watchers.push(watcher); // pushing the Watcher Object to Watchers
};
There is an interesting thing in Angular called Digest Cycle. The $digest cycle starts as a result of a call to $scope.$digest(). Assume that you change a $scope model in a handler function through the ng-click directive. In that case AngularJS automatically triggers a $digest cycle by calling $digest().In addition to ng-click, there are several other built-in directives/services that let you change models (e.g. ng-model, $timeout, etc) and automatically trigger a $digest cycle. The rough implementation of $digest looks like this.
Scope.prototype.$digest = function() {
var dirty;
do {
dirty = this.$$digestOnce();
} while (dirty);
}
Scope.prototype.$$digestOnce = function() {
var self = this;
var newValue, oldValue, dirty;
_.forEach(this.$$watchers, function(watcher) {
newValue = watcher.watchFn(self);
oldValue = watcher.last; // It just remembers the last value for dirty checking
if (newValue !== oldValue) { //Dirty checking of References
// For Deep checking the object , code of Value
// based checking of Object should be implemented here
watcher.last = newValue;
watcher.listenerFn(newValue,
(oldValue === initWatchVal ? newValue : oldValue),
self);
dirty = true;
}
});
return dirty;
};
If we use JavaScript’s setTimeout() function to update a scope model, Angular has no way of knowing what you might change. In this case it’s our responsibility to call $apply() manually, which triggers a $digest cycle. Similarly, if you have a directive that sets up a DOM event listener and changes some models inside the handler function, you need to call $apply() to ensure the changes take effect. The big idea of $apply is that we can execute some code that isn't aware of Angular, that code may still change things on the scope. If we wrap that code in $apply , it will take care of calling $digest(). Rough implementation of $apply().
Scope.prototype.$apply = function(expr) {
try {
return this.$eval(expr); //Evaluating code in the context of Scope
} finally {
this.$digest();
}
};
Nick Craver's solution works but you can also use this:
:nth-last-child(n+2) { /* Your code here */ }
Chris Coyier of CSS Tricks made a nice :nth tester for this.
You can write like that. This is for whenever you change context path you don't need to modify your jsp file.
<link rel="stylesheet" href="${pageContext.request.contextPath}/css/styles.css" />
you can also use a hashmap for this
@GetMapping
public HashMap<String, Object> get() {
HashMap<String, Object> map = new HashMap<>();
map.put("key1", "value1");
map.put("results", somePOJO);
return map;
}
You could run: mvn exec:exec -Dexec.args="arg1"
.
This will pass the argument arg1 to your program.
You should specify the main class fully qualified, for example, a Main.java that is in a package test would need
mvn exec:java -Dexec.mainClass=test.Main
By using the -f
parameter, as decribed here, you can also run it from other directories.
mvn exec:java -Dexec.mainClass=test.Main -f folder/pom.xm
For multiple arguments, simply separate them with a space as you would at the command line.
mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="arg1 arg2 arg3"
For arguments separated with a space, you can group using 'argument separated with space'
inside the quotation marks.
mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="'argument separated with space' 'another one'"
An example with code, perhaps.
Here, the ConcreteRegistry is a singleton in a poker game that allows the behaviours all the way up the package tree access the few, core interfaces of the game (i.e., the facades for the model, view, controller, environment, etc.):

Ed.
Assuming you are using this for a web service, you can just apply the following attribute to the class:
[System.Web.Script.Services.ScriptService]
Then the following attribute to each method that should return Json:
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
And set the return type for the methods to be "object"
If you want the previous year and month relative to a specific date and have DateTime available then you can do this:
$d = new DateTime('2013-01-01', new DateTimeZone('UTC'));
$d->modify('first day of previous month');
$year = $d->format('Y'); //2012
$month = $d->format('m'); //12
I set the PHPRC variable and uncommented zend_extension=php_opcache.dll
in php.ini
and all works well.
Very easy method to get the Last digit:
int myInt = 1821;
int lastDigit = myInt - ((myInt/10)*10); // 1821 - 1820 = 1
Use boost::filesystem:
#include <boost/filesystem.hpp>
if ( !boost::filesystem::exists( "myfile.txt" ) )
{
std::cout << "Can't find my file!" << std::endl;
}
Android app package name?
Just for the record, my case concerned an android app so if it concerns renaming the package name in an android application, then you can do it directly from the AndroidManifest.xml file, it's the first field in the android manifest, you change your package name and update it. Then if it shows you errors, so just "clean" your project in the "project" menu.
Goal: save a piece of one file to another file.
Solution:
Save selected text to the new file. Type :wSpace and the name of the new file. Actually you'll see
:'<,'>w new.txt
Then press Enter
Options and dependencies need to be inside arrays:
namespace :thing do
desc "it does a thing"
task :work, [:option, :foo, :bar] do |task, args|
puts "work", args
end
task :another, [:option, :foo, :bar] do |task, args|
puts "another #{args}"
Rake::Task["thing:work"].invoke(args[:option], args[:foo], args[:bar])
# or splat the args
# Rake::Task["thing:work"].invoke(*args)
end
end
Then
rake thing:work[1,2,3]
=> work: {:option=>"1", :foo=>"2", :bar=>"3"}
rake thing:another[1,2,3]
=> another {:option=>"1", :foo=>"2", :bar=>"3"}
=> work: {:option=>"1", :foo=>"2", :bar=>"3"}
NOTE: variable
task
is the task object, not very helpful unless you know/care about Rake internals.
RAILS NOTE:
If running the task from Rails, it's best to preload the environment by adding
=> [:environment]
which is a way to setup dependent tasks.
task :work, [:option, :foo, :bar] => [:environment] do |task, args|
puts "work", args
end
You can solve this issue be adding max-width
:
#element {
width: 100vw;
height: 100vw;
max-width: 100%;
}
When you using CSS to make the wrapper full width using the code width: 100vw;
then you will notice a horizontal scroll in the page, and that happened because the padding
and margin
of html
and body
tags added to the wrapper size, so the solution is to add max-width: 100%
There are currently three distinct events which may or may not be triggered when the client devices moves. Two of them are focused around orientation and the last on motion:
ondeviceorientation
is known to work on the desktop version of Chrome, and most Apple laptops seems to have the hardware required for this to work. It also works on Mobile Safari on the iPhone 4 with iOS 4.2. In the event handler function, you can access alpha
, beta
, gamma
values on the event data supplied as the only argument to the function.
onmozorientation
is supported on Firefox 3.6 and newer. Again, this is known to work on most Apple laptops, but might work on Windows or Linux machines with accelerometer as well. In the event handler function, look for x
, y
, z
fields on the event data supplied as first argument.
ondevicemotion
is known to work on iPhone 3GS + 4 and iPad (both with iOS 4.2), and provides data related to the current acceleration of the client device. The event data passed to the handler function has acceleration
and accelerationIncludingGravity
, which both have three fields for each axis: x
, y
, z
The "earthquake detecting" sample website uses a series of if
statements to figure out which event to attach to (in a somewhat prioritized order) and passes the data received to a common tilt
function:
if (window.DeviceOrientationEvent) {
window.addEventListener("deviceorientation", function () {
tilt([event.beta, event.gamma]);
}, true);
} else if (window.DeviceMotionEvent) {
window.addEventListener('devicemotion', function () {
tilt([event.acceleration.x * 2, event.acceleration.y * 2]);
}, true);
} else {
window.addEventListener("MozOrientation", function () {
tilt([orientation.x * 50, orientation.y * 50]);
}, true);
}
The constant factors 2 and 50 are used to "align" the readings from the two latter events with those from the first, but these are by no means precise representations. For this simple "toy" project it works just fine, but if you need to use the data for something slightly more serious, you will have to get familiar with the units of the values provided in the different events and treat them with respect :)
User: Access to resource of the database. Like a key to enter a house.
Schema: Collection of information about database objects. Like Index in your book which contains the short information about the chapter.
After installing pytorch, I got a similar error when I used:

Removing NumPy didn't help (I actually renamed NumPy, so I reverted back after it didn't work). The following commands worked for me:
sudo pip install numpy --upgrade
sudo easy_install numpy
In MySQL you could try:
SELECT * FROM A INNER JOIN B ON B.MYCOL LIKE CONCAT('%', A.MYCOL, '%');
Of course this would be a massively inefficient query because it would do a full table scan.
Update: Here's a proof
create table A (MYCOL varchar(255));
create table B (MYCOL varchar(255));
insert into A (MYCOL) values ('foo'), ('bar'), ('baz');
insert into B (MYCOL) values ('fooblah'), ('somethingfooblah'), ('foo');
insert into B (MYCOL) values ('barblah'), ('somethingbarblah'), ('bar');
SELECT * FROM A INNER JOIN B ON B.MYCOL LIKE CONCAT('%', A.MYCOL, '%');
+-------+------------------+
| MYCOL | MYCOL |
+-------+------------------+
| foo | fooblah |
| foo | somethingfooblah |
| foo | foo |
| bar | barblah |
| bar | somethingbarblah |
| bar | bar |
+-------+------------------+
6 rows in set (0.38 sec)
Note, from 2015 onwards, just use backticks for templating
https://stackoverflow.com/a/37245773/294884
let a = `hello ${name}` // NOTE!!!!!!!! ` not ' or "
Note that it is a backtick, not a quote.
If you want to have something similar, you could create a function:
function parse(str) {
var args = [].slice.call(arguments, 1),
i = 0;
return str.replace(/%s/g, () => args[i++]);
}
Usage:
s = parse('hello %s, how are you doing', my_name);
This is only a simple example and does not take into account different kinds of data types (like %i
, etc) or escaping of %s
. But I hope it gives you some idea. I'm pretty sure there are also libraries out there which provide a function like this.
The error happens because of you are trying to map a numeric vector to data
in geom_errorbar
: GVW[1:64,3]
. ggplot
only works with data.frame
.
In general, you shouldn't subset inside ggplot
calls. You are doing so because your standard errors are stored in four separate objects. Add them to your original data.frame
and you will be able to plot everything in one call.
Here with a dplyr
solution to summarise the data and compute the standard error beforehand.
library(dplyr)
d <- GVW %>% group_by(Genotype,variable) %>%
summarise(mean = mean(value),se = sd(value) / sqrt(n()))
ggplot(d, aes(x = variable, y = mean, fill = Genotype)) +
geom_bar(position = position_dodge(), stat = "identity",
colour="black", size=.3) +
geom_errorbar(aes(ymin = mean - se, ymax = mean + se),
size=.3, width=.2, position=position_dodge(.9)) +
xlab("Time") +
ylab("Weight [g]") +
scale_fill_hue(name = "Genotype", breaks = c("KO", "WT"),
labels = c("Knock-out", "Wild type")) +
ggtitle("Effect of genotype on weight-gain") +

Providing javac
is set up through /etc/alternatives/javac
, you can add to your .bash_profile:
JAVA_HOME=$(l=$(which javac) ; while : ; do nl=$(readlink ${l}) ; [ "$nl" ] || break ; l=$nl ; done ; echo $(cd $(dirname $l)/.. ; pwd) )
export JAVA_HOME
as text:
=CONCATENATE(TEXT(cell;"d");" days ";TEXT(cell;"t");" hours ";MID(TEXT(cell;"hh:mm:ss");4;2);" minutes ";TEXT(cell;"s");" seconds")
display:
is not transitionable. You'll probably need to use jQuery to do what you want to do.
Logins are not too complicated, but there are some specific pieces that almost all login processes need.
First, make sure you enable the session variable on all pages that require knowledge of logged-in status by putting this at the beginning of those pages:
session_start();
Next, when the user submits their username and password via the login form, you will typically check their username and password by querying a database containing username and password information, such as MySQL. If the database returns a match, you can then set a session variable to contain that fact. You might also want to include other information:
if (match_found_in_database()) {
$_SESSION['loggedin'] = true;
$_SESSION['username'] = $username; // $username coming from the form, such as $_POST['username']
// something like this is optional, of course
}
Then, on the page that depends on logged-in status, put the following (don't forget the session_start()
):
if (isset($_SESSION['loggedin']) && $_SESSION['loggedin'] == true) {
echo "Welcome to the member's area, " . $_SESSION['username'] . "!";
} else {
echo "Please log in first to see this page.";
}
Those are the basic components. If you need help with the SQL aspect, there are tutorials-a-plenty around the net.
If you want a list of lists:
>>> [list(t) for t in zip(*l)]
[[1, 3, 8], [2, 4, 9]]
If a list of tuples is OK:
>>> zip(*l)
[(1, 3, 8), (2, 4, 9)]
If you want to see just the subject (first line) of the commit message:
git log -1 --format=%s
This was not previously documented in any answer. Alternatively, the approach by nos also shows it.
Reference:
You may do:
a= [1,1,1,2,2,3]
delete_list = [1,3]
delete_list.each do |del|
a.delete_at(a.index(del))
end
result : [1, 1, 2, 2]
There several answers here that don't handle simple edge cases like negative step, wrong start, stop etc. Here's the version that handles many of these cases correctly giving same behaviour as native range()
:
def frange(start, stop=None, step=1):
if stop is None:
start, stop = 0, start
steps = int((stop-start)/step)
for i in range(steps):
yield start
start += step
Note that this would error out step=0 just like native range
. One difference is that native range returns object that is indexable and reversible while above doesn't.
You can play with this code and test cases here.
Instead of writing
<hr>
Write
<hr class="col-xs-12">
And it will display full width as normal.
You can also use this node module called js-xlsx
1) Install module
npm install xlsx
2) Import module + code snippet
var XLSX = require('xlsx')
var workbook = XLSX.readFile('Master.xlsx');
var sheet_name_list = workbook.SheetNames;
var xlData = XLSX.utils.sheet_to_json(workbook.Sheets[sheet_name_list[0]]);
console.log(xlData);
Did you try refreshing (right click -> refresh) the project folder after copying the file in there? That will SYNC your file system with Eclipse's internal file system.
When you run Eclipse projects, the CWD (current working directory) is project's root directory. Not bin's directory. Not src's directory, but the root dir.
Also, if you're in Linux, remember that its file systems are usually case sensitive.
If none of them are working then check this.. say if you have x and y arrays of data along respective axis. Then check in which cell(jupyter) you have initialized x and y to empty. This is because , maybe you are appending data to x and y without re-initializing them. So plot has old data too. So check that..

I had a similar requirement; documenting my approach here for anyone with a similar scenario...
Use SQL Server Schema Comparison (from SQL Server Data Tools / Visual Studio) to compare source (clean install) with destination (the db with invalid collation).
In my case I compared the two DBs directly; though you could work via a project to allow you to manually tweak pieces in between...
Object Types
select only those types you're interested in (for me it was only Views
and Tables
)General
select:
DELETE
folder and selecting EXCLUDE
.CREATE
objects (here since they don't exist in the target they can't have the wrong collation there; whether they should exist is a question for another topic).Update
to push changesThis does still involve some manual effort (e.g. checking that you're only impacting the collation) - but it handles dependencies for you.
Also you can keep a database project of the valid schema so you can use a universal template for your DBs should you have more than 1 to update, assuming all target DBs should end up with the same schema.
You can also use find/replace on the files in a database project should you wish to mass amend settings there (e.g. so you could create the project from the invalid database using schema compare, amend the project files, then toggle the source/target in the schema compare to push your changes back to the DB).
when you perform y=x()
you are actually assigning y to the result of calling the function object x
and the function has a return value of None
. Function calls in python are performed using ()
. To assign x to y
so you can call y
just like you would x
you assign the function object x to y like y=x
and call the function using y()
EDIT: first try the new pip method:
Windows: pip3 install opencv-python opencv-contrib-python
Ubuntu: sudo apt install python3-opencv
or continue below for build instructions
Note: The original question was asking for OpenCV + Python 3.3 + Windows. Since then, Python 3.5 has been released. In addition, I use Ubuntu for most development so this answer will focus on that setup, unfortunately
OpenCV 3.1.0 + Python 3.5.2 + Ubuntu 16.04 is possible! Here's how.
These steps are copied (and slightly modified) from:
Install the required dependencies and optionally install/update some libraries on your system:
# Required dependencies
sudo apt install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
# Dependencies for Python bindings
# If you use a non-system copy of Python (eg. with pyenv or virtualenv), then you probably don't need to do this part
sudo apt install python3.5-dev libpython3-dev python3-numpy
# Optional, but installing these will ensure you have the latest versions compiled with OpenCV
sudo apt install libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
There are several flags and options to tweak your build of OpenCV. There might be comprehensive documentation about them, but here are some interesting flags that may be of use. They should be included in the cmake
command:
# Builds in TBB, a threading library
-D WITH_TBB=ON
# Builds in Eigen, a linear algebra library
-D WITH_EIGEN=ON
If you have multiple versions of Python (eg. from using pyenv or virtualenv), then you may want to build against a certain Python version. By default OpenCV will build for the system's version of Python. You can change this by adding these arguments to the cmake
command seen later in the script. Actual values will depend on your setup. I use pyenv
:
-D PYTHON_DEFAULT_EXECUTABLE=$HOME/.pyenv/versions/3.5.2/bin/python3.5
-D PYTHON_INCLUDE_DIRS=$HOME/.pyenv/versions/3.5.2/include/python3.5m
-D PYTHON_EXECUTABLE=$HOME/.pyenv/versions/3.5.2/bin/python3.5
-D PYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so.1
The CMakeLists file will try to detect various versions of Python to build for. If you've got different versions here, it might get confused. The above arguments may only "fix" the issue for one version of Python but not the other. If you only care about that specific version, then there's nothing else to worry about.
This is the case for me so unfortunately, I haven't looked into how to resolve the issues with other Python versions.
# Clone OpenCV somewhere
# I'll put it into $HOME/code/opencv
OPENCV_DIR="$HOME/code/opencv"
OPENCV_VER="3.1.0"
git clone https://github.com/opencv/opencv "$OPENCV_DIR"
# This'll take a while...
# Now lets checkout the specific version we want
cd "$OPENCV_DIR"
git checkout "$OPENCV_VER"
# First OpenCV will generate the files needed to do the actual build.
# We'll put them in an output directory, in this case "release"
mkdir release
cd release
# Note: This is where you'd add build options, like TBB support or custom Python versions. See above sections.
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local "$OPENCV_DIR"
# At this point, take a look at the console output.
# OpenCV will print a report of modules and features that it can and can't support based on your system and installed libraries.
# The key here is to make sure it's not missing anything you'll need!
# If something's missing, then you'll need to install those dependencies and rerun the cmake command.
# OK, lets actually build this thing!
# Note: You can use the "make -jN" command, which will run N parallel jobs to speed up your build. Set N to whatever your machine can handle (usually <= the number of concurrent threads your CPU can run).
make
# This will also take a while...
# Now install the binaries!
sudo make install
By default, the install
script will put the Python bindings in some system location, even if you've specified a custom version of Python to use. The fix is simple: Put a symlink to the bindings in your local site-packages
:
ln -s /usr/local/lib/python3.5/site-packages/cv2.cpython-35m-x86_64-linux-gnu.so $HOME/.pyenv/versions/3.5.2/lib/python3.5/site-packages/
The first path will depend on the Python version you setup to build. The second depends on where your custom version of Python is located.
OK lets try it out!

Sorry for the short answer but it is late. Google "oracle event 10046 sql trace". It would be best to trace an individual session because figuring which SQL belongs to which session from v$sql is no easy if it is shared sql and being used by multiple users.
If you want to impress your Oracle DBA friends, learn how to set an oracle trace with event 10046, interpret the meaning of the wait events and find the top cpu consumers.
Quest had a free product that allowed you to capture the SQL as it went out from the client side but not sure if it works with your product/version of Oracle. Google "quest oracle sql monitor" for this.
Good night.
There are so many answers up there, I will post my answer for my reference. I use webpack and react, here is my solution without the .babelrc file
I am working on this in Aug 2020
Install react and babel
npm i @babel/core babel-loader @babel/preset-env @babel/preset-react react react-dom @babel/plugin-transform-runtime --save-dev
Then in my webpack.config.js
// other stuff
module.exports = {
// other stuff
module: {
rules: [
{
test: /\.m?js$/,
exclude: /(node_modules|bower_components)/,
use: {
loader: 'babel-loader',
options: {
presets: ['@babel/preset-env',"@babel/preset-react"],
plugins: ['@babel/plugin-proposal-class-properties', '@babel/plugin-transform-runtime'],
//npm install --save-dev @babel/plugin-transform-runtime
}
}
},
],
},
};
I just don't know why I dont need to install the async package for the moment
I put together a little test here:
\documentclass[10pt,twocolumn]{article}
\title{Article Title}

\section{Introduction}
\ldots
\end{document}
Things to note, the title, author and date fields are declared before \begin{document}
. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn
in the document class.
This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}
. Here's a more detailed article on \LaTeX
font sizes:
https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont
To italicize you can use {\it First Name}
or \textit{First Name}
.
Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.
For Those who are facing difficulty just got to php admin and change collation to utf8_general_ci Select Table go to Operations>> table options>> collations should be there
Also, this will go up a directory and then back down to another subfolder.
<a href = "../subfolder/page.html">link</a>
To go up multiple directories you can do this.
<a href = "../../page.html">link</a>
To go the root, I use this
<a href = "~/page.html">link</a>
I did
$(".navbar-toggle").click(function(event) {
$(".navbar-collapse").toggle('in');
});
The reason this is happening is because initializing an array does not initialize each element in that array. You need to first set houses[0] = new GameObject()
and then it will work.
You have a lot of type-mismatches in your code such as trying to put an int
value where BigDecimal
is required. The corrected version of your code:
public class Payment
{
BigDecimal itemCost = BigDecimal.ZERO;
BigDecimal totalCost = BigDecimal.ZERO;
public BigDecimal calculateCost(int itemQuantity, BigDecimal itemPrice)
{
itemCost = itemPrice.multiply(new BigDecimal(itemQuantity));
totalCost = totalCost.add(itemCost);
return totalCost;
}
}
Ctrl+Shift+k
and push the project to repository.
It works.In the "Window" menu, open "Open Perspective" -> "Debug".
click On the plus image icon(you see the below image at status bar), and then select "Logcat"....
There could be two easy solutions:
What is blob url? Why it is used?
BLOB is just byte sequence. Browser recognize it as byte stream. It is used to get byte stream from source.
A Blob object represents a file-like object of immutable, raw data. Blobs represent data that isn't necessarily in a JavaScript-native format. The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system.
Can i make my own blob url on a server?
Yes you can there are serveral ways to do so for example try http://php.net/manual/en/function.ibase-blob-echo.php

Use getopt
Why getopt?
To parse elaborated command-line arguments to avoid confusion and clarify the options we are parsing so that reader of the commands can understand what's happening.
What is getopt?
getopt
is used to break up (parse) options in command lines for easy parsing by shell procedures, and to check for legal options. It uses the GNU getopt(3)
routines to do this.
getopt
can have following types of options.
Note: In this document, during explaining syntax:
HOW TO USE getopt
?
Syntax: First Form
getopt optstring parameters
Examples:
# This is correct
getopt "hv:t::" "-v 123 -t123"
getopt "hv:t::" "-v123 -t123" # -v and 123 doesn't have whitespace
# -h takes no value.
getopt "hv:t::" "-h -v123"
# This is wrong. after -t can't have whitespace.
# Only optional params cannot have whitespace between key and value
getopt "hv:t::" "-v 123 -t 123"
# Multiple arguments that takes value.
getopt "h:v:t::g::" "-h abc -v 123 -t21"
# Multiple arguments without value
# All of these are correct
getopt "hvt" "-htv"
getopt "hvt" "-h -t -v"
getopt "hvt" "-tv -h"
Here h,v,t are the options and -h -v -t is how options should be given in command-line.
In optional param, value cannot have whitespace separation with the option. So, in "-t123" example, -t is option 123 is value.
Syntax: Second Form
getopt [getopt_options] [--] [optstring] [parameters]
Here after getopt is split into five parts
Examples
getopt -l "name:,version::,verbose" -- "n:v::V" "--name=Karthik -version=5.2 -verbose"
Syntax: Third Form
getopt [getopt_options] [-o options] [--] [optstring] [parameters]
Here after getopt is split into five parts
Examples
getopt -l "name:,version::,verbose" -a -o "n:v::V" -- "-name=Karthik -version=5.2 -verbose"
GETOPT_OPTIONS
getopt_options changes the way command-line params are parsed.
Below are some of the getopt_options
Option: -l or --longoptions
Means getopt command should allow multi-character options to be recognised. Multiple options are separated by comma.
For example, --name=Karthik
is a long option sent in command line. In getopt, usage of long options are like
getopt "name:,version" "--name=Karthik"
Since name: is specified, the option should contain a value
Option: -a or --alternative
Means getopt command should allow long option to have a single dash '-' rather than double dash '--'.
Example, instead of --name=Karthik
you could use just -name=Karthik
getopt "name:,version" "-name=Karthik"
A complete script example with the code:
#!/bin/bash
# filename: commandLine.sh
# author: @theBuzzyCoder
showHelp() {
# `cat << EOF` This means that cat should stop reading when EOF is detected
cat << EOF
Usage: ./installer -v <espo-version> [-hrV]
Install Pre-requisites for EspoCRM with docker in Development mode
-h, -help, --help Display help
-v, -espo-version, --espo-version Set and Download specific version of EspoCRM
-r, -rebuild, --rebuild Rebuild php vendor directory using composer and compiled css using grunt
-V, -verbose, --verbose Run script in verbose mode. Will print out each step of execution.
EOF
# EOF is found above and hence cat command stops reading. This is equivalent to echo but much neater when printing out.
}
export version=0
export verbose=0
export rebuilt=0
# $@ is all command line parameters passed to the script.
# -o is for short options like -v
# -l is for long options with double dash like --version
# the comma separates different long options
# -a is for long options with single dash like -version
options=$(getopt -l "help,version:,verbose,rebuild,dryrun" -o "hv:Vrd" -a -- "$@")
# set --:
# If no arguments follow this option, then the positional parameters are unset. Otherwise, the positional parameters
# are set to the arguments, even if some of them begin with a ‘-’.
eval set -- "$options"
while true
do
case $1 in
-h|--help)
showHelp
exit 0
;;
-v|--version)
shift
export version=$1
;;
-V|--verbose)
export verbose=1
set -xv # Set xtrace and verbose mode.
;;
-r|--rebuild)
export rebuild=1
;;
--)
shift
break;;
esac
shift
done
Running this script file:
# With short options grouped together and long option
# With double dash '--version'
bash commandLine.sh --version=1.0 -rV
# With short options grouped together and long option
# With single dash '-version'
bash commandLine.sh -version=1.0 -rV
# OR with short option that takes value, value separated by whitespace
# by key
bash commandLine.sh -v 1.0 -rV
# OR with short option that takes value, value without whitespace
# separation from key.
bash commandLine.sh -v1.0 -rV
# OR Separating individual short options
bash commandLine.sh -v1.0 -r -V

To set an env variable in a jupyter notebook, just use a %
magic commands, either %env
or %set_env
, e.g., %env MY_VAR=MY_VALUE
or %env MY_VAR MY_VALUE
. (Use %env
by itself to print out current environmental variables.)
See: http://ipython.readthedocs.io/en/stable/interactive/magics.html
The legacy solution, before 1.6, was to use .attr
and handle the returned value as a bool
. The main problem is that the returned type of .attr
has changed to string
, and therefore the comparison with == true
is broken (see http://jsfiddle.net/2vene/1/ (and switch the jquery-version)).
With 1.6 .prop
was introduced, which returns a bool
.
Nevertheless, I suggest to use .is()
, as the returned type is intrinsically bool
, like:
$('#dropUnit').is(':disabled');
$('#dropUnit').is(':enabled');
Furthermore .is()
is much more natural (in terms of "natural language") and adds more conditions than a simple attribute-comparison (eg: .is(':last')
, .is(':visible')
, ... please see documentation on selectors).
Add authorization header and click pencil button to enter username and passwords
user334291's answer was a life saver for me. Just want to add how you can add what the OP originally intended to do (what I ended up using):
Overriding the GetWebRequest function on the generated webservice code:
protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
System.Net.WebRequest request = base.GetWebRequest(uri);
string auth = "Basic " + Convert.ToBase64String(System.Text.Encoding.Default.GetBytes(this.Credentials.GetCredential(uri, "Basic").UserName + ":" + this.Credentials.GetCredential(uri, "Basic").Password));
request.Headers.Add("Authorization", auth);
return request;
}
and setting the credentials before calling the webservice:
client.Credentials = new NetworkCredential(user, password);
I recently had to solve this problem too, and after a LOT of trial and error I came up with this (in PHP, but maps directly to the DSL):
'query' => [
'bool' => [
'should' => [
['prefix' => ['name_first' => $query]],
['prefix' => ['name_last' => $query]],
['prefix' => ['phone' => $query]],
['prefix' => ['email' => $query]],
[
'multi_match' => [
'query' => $query,
'type' => 'cross_fields',
'operator' => 'and',
'fields' => ['name_first', 'name_last']
]
]
],
'minimum_should_match' => 1,
'filter' => [
['term' => ['state' => 'active']],
['term' => ['company_id' => $companyId]]
]
]
]
Which maps to something like this in SQL:
SELECT * from <index>
WHERE (
name_first LIKE '<query>%' OR
name_last LIKE '<query>%' OR
phone LIKE '<query>%' OR
email LIKE '<query>%'
)
AND state = 'active'
AND company_id = <query>
The key in all this is the minimum_should_match
setting. Without this the filter
totally overrides the should
.
Hope this helps someone!
Given:
A_1 = [10 200 7 150]';
A_2 = [0.001 0.450 0.007 0.200]';
(As others have already pointed out) There are tools to simply compute correlation, most obviously corr
:
corr(A_1, A_2); %Returns 0.956766573975184 (Requires stats toolbox)
You can also use base Matlab's corrcoef
function, like this:
M = corrcoef([A_1 A_2]): %Returns [1 0.956766573975185; 0.956766573975185 1];
M(2,1); %Returns 0.956766573975184
Which is closely related to the cov
function:
cov([condition(A_1) condition(A_2)]);
As you almost get to in your original question, you can scale and adjust the vectors yourself if you want, which gives a slightly better understanding of what is going on. First create a condition function which subtracts the mean, and divides by the standard deviation:
condition = @(x) (x-mean(x))./std(x); %Function to subtract mean AND normalize standard deviation
Then the correlation appears to be (A_1 * A_2)/(A_1^2), like this:
(condition(A_1)' * condition(A_2)) / sum(condition(A_1).^2); %Returns 0.956766573975185
By symmetry, this should also work
(condition(A_1)' * condition(A_2)) / sum(condition(A_2).^2); %Returns 0.956766573975185
And it does.
I believe, but don't have the energy to confirm right now, that the same math can be used to compute correlation and cross correlation terms when dealing with multi-dimensiotnal inputs, so long as care is taken when handling the dimensions and orientations of the input arrays.
This is old question but still my answer may help someone

No, you don't need to add them as a remote. That would be clumbersome and a pain to do each time.
git fetch [email protected]:theirusername/reponame.git theirbranch:ournameforbranch
This creates a local branch named ournameforbranch
which is exactly the same as what theirbranch
was for them. For the question example, the last argument would be foo:foo
.
Note :ournameforbranch
part can be further left off if thinking up a name that doesn't conflict with one of your own branches is bothersome. In that case, a reference called FETCH_HEAD
is available. You can git log FETCH_HEAD
to see their commits then do things like cherry-picked
to cherry pick their commits.
Oftentimes, you want to fix something of theirs and push it right back. That's possible too:
git fetch [email protected]:theirusername/reponame.git theirbranch
git checkout FETCH_HEAD
# fix fix fix
git push [email protected]:theirusername/reponame.git HEAD:theirbranch
If working in detached state worries you, by all means create a branch using :ournameforbranch
and replace FETCH_HEAD
and HEAD
above with ournameforbranch

The following seems to work for my use cases:
$ tern 1 YES NO
YES
$ tern 0 YES NO
NO
$ tern 52 YES NO
YES
$ tern 52 YES NO 52
NO
and can be used in a script like so:
RESULT=$(tern 1 YES NO)
echo "The result is $RESULT"
function show_help()
{
echo ""
echo "usage: BOOLEAN VALUE_IF_TRUE VALUE_IF_FALSE {FALSE_VALUE}"
echo ""
echo "e.g. "
echo ""
echo "tern 1 YES NO => YES"
echo "tern 0 YES NO => NO"
echo "tern "" YES NO => NO"
echo "tern "ANY STRING THAT ISNT 1" YES NO => NO"
echo "ME=$(tern 0 YES NO) => ME contains NO"
echo ""
exit
}
if [ "$1" == "help" ]
then
show_help
fi
if [ -z "$3" ]
then
show_help
fi
# Set a default value for what is "false" -> 0
FALSE_VALUE=${4:-0}
function main
{
if [ "$1" == "$FALSE_VALUE" ]; then
echo $3
exit;
fi;
echo $2
}
main "$1" "$2" "$3"
From the code that you have provided, not knowing the language that you are programming in. The variable capital
is null. When you are trying to read the property length, the system cant as it is trying to deference a null variable. You need to define capital
.
Another alternative with data.table.
EXAMPLE DATA
dt1 <- data.table(df1)
dt2 <- data.table(df2)
setkey(dt1,x)
setkey(dt2,x)
CODE
dt2[dt1,list(y=ifelse(is.na(y),0,y))]
Do something like this:
A <div>
with ID of #imageDIV
, another one with ID #download
and a hidden <div>
with ID #previewImage
.
Include the latest version of jquery, and jspdf.debug.js from the jspdf CDN
Then add this script:
var element = $("#imageDIV"); // global variable
var getCanvas; // global variable
$('document').ready(function(){
html2canvas(element, {
onrendered: function (canvas) {
$("#previewImage").append(canvas);
getCanvas = canvas;
}
});
});
$("#download").on('click', function () {
var imgageData = getCanvas.toDataURL("image/png");
// Now browser starts downloading it instead of just showing it
var newData = imageData.replace(/^data:image\/png/, "data:application/octet-stream");
$("#download").attr("download", "image.png").attr("href", newData);
});
The div will be saved as a PNG on clicking the #download
A PDOStatement
(which you have in $users
) is a forward-cursor. That means, once consumed (the first foreach
iteration), it won't rewind to the beginning of the resultset.
You can close the cursor after the foreach
and execute the statement again:
$users = $dbh->query($sql);
foreach ($users as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
$users->execute();
foreach ($users as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
Or you could cache using tailored CachingIterator
with a fullcache:
$users = $dbh->query($sql);
$usersCached = new CachedPDOStatement($users);
foreach ($usersCached as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
foreach ($usersCached as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
You find the CachedPDOStatement
class as a gist. The caching itertor is probably more sane than storing the resultset into an array because it still offers all properties and methods of the PDOStatement
object it has wrapped.
As I understand Copy-Item -Exclude
then you are doing it correct. What I usually do, get 1'st, and then do after, so what about using Get-Item
as in
Get-Item -Path $copyAdmin -Exclude $exclude |
Copy-Item -Path $copyAdmin -Destination $AdminPath -Recurse -force
I found the solution to a similar problem. I am using Gradle 1.11 (as April, 2014). The project name can be changed directly in settings.gradle
file as following:
rootProject.name='YourNewName'
This takes care of uploading to repository (Artifactory w/ its plugin for me) with the correct artifactId.
I want to share my solution for the 'problem'. I haven't re-invented the wheel but tries to find a solution based on what JavaScript already does. The advantage is, that you get all implicit conversions for free. Setting the prototype property $ of String gives a very nice and compact syntax (see examples below). It is maybe not the most efficient way, but in most cases dealing with output it does not have to be super optimized.
String.form = function(str, arr) {
var i = -1;
function callback(exp, p0, p1, p2, p3, p4) {
if (exp=='%%') return '%';
if (arr[++i]===undefined) return undefined;
exp = p2 ? parseInt(p2.substr(1)) : undefined;
var base = p3 ? parseInt(p3.substr(1)) : undefined;
var val;
switch (p4) {
case 's': val = arr[i]; break;
case 'c': val = arr[i][0]; break;
case 'f': val = parseFloat(arr[i]).toFixed(exp); break;
case 'p': val = parseFloat(arr[i]).toPrecision(exp); break;
case 'e': val = parseFloat(arr[i]).toExponential(exp); break;
case 'x': val = parseInt(arr[i]).toString(base?base:16); break;
case 'd': val = parseFloat(parseInt(arr[i], base?base:10).toPrecision(exp)).toFixed(0); break;
}
val = typeof(val)=='object' ? JSON.stringify(val) : val.toString(base);
var sz = parseInt(p1); /* padding size */
var ch = p1 && p1[0]=='0' ? '0' : ' '; /* isnull? */
while (val.length<sz) val = p0 !== undefined ? val+ch : ch+val; /* isminus? */
return val;
}
var regex = /%(-)?(0?[0-9]+)?([.][0-9]+)?([#][0-9]+)?([scfpexd%])/g;
return str.replace(regex, callback);
}
String.prototype.$ = function() {
return String.form(this, Array.prototype.slice.call(arguments));
}
Here are a few examples:
String.format("%s %s", [ "This is a string", 11 ])
console.log("%s %s".$("This is a string", 11))
var arr = [ "12.3", 13.6 ]; console.log("Array: %s".$(arr));
var obj = { test:"test", id:12 }; console.log("Object: %s".$(obj));
console.log("%c", "Test");
console.log("%5d".$(12)); // ' 12'
console.log("%05d".$(12)); // '00012'
console.log("%-5d".$(12)); // '12 '
console.log("%5.2d".$(123)); // ' 120'
console.log("%5.2f".$(1.1)); // ' 1.10'
console.log("%10.2e".$(1.1)); // ' 1.10e+0'
console.log("%5.3p".$(1.12345)); // ' 1.12'
console.log("%5x".$(45054)); // ' affe'
console.log("%20#2x".$("45054")); // ' 1010111111111110'
console.log("%6#2d".$("111")); // ' 7'
console.log("%6#16d".$("affe")); // ' 45054'

I assume you know what a byte is. A byte array is simply an area of memory containing a group of contiguous (side by side) bytes, such that it makes sense to talk about them in order: the first byte, the second byte etc..
Just as bytes can encode different types and ranges of data (numbers from 0 to 255, numbers from -128 to 127, single characters using ASCII e.g. 'a' or '%', CPU op-codes), each byte in a byte array may be any of these things, or contribute to some multi-byte values such as numbers with larger range (e.g. 16-bit unsigned int from 0..65535), international character sets, textual strings ("hello"), or part/all of a compiled computer programs.
The crucial thing about a byte array is that it gives indexed (fast), precise, raw access to each 8-bit value being stored in that part of memory, and you can operate on those bytes to control every single bit. The bad thing is the computer just treats every entry as an independent 8-bit number - which may be what your program is dealing with, or you may prefer some powerful data-type such as a string that keeps track of its own length and grows as necessary, or a floating point number that lets you store say 3.14 without thinking about the bit-wise representation. As a data type, it is inefficient to insert or remove data near the start of a long array, as all the subsequent elements need to be shuffled to make or fill the gap created/required.
What worked for me is:

For those who use JUnit 5, Powermock is not an option. You'll require the following dependencies to successfully mock a static method with just Mockito.
testCompile group: 'org.mockito', name: 'mockito-core', version: '3.6.0'
testCompile group: 'org.mockito', name: 'mockito-junit-jupiter', version: '3.6.0'
testCompile group: 'org.mockito', name: 'mockito-inline', version: '3.6.0'
mockito-junit-jupiter
add supports for JUnit 5.
And support for mocking static methods is provided by mockito-inline
dependency.
Example:
@Test
void returnUtilTest() {
assertEquals("foo", UtilClass.staticMethod("foo"));
try (MockedStatic<UtilClass> classMock = mockStatic(UtilClass.class)) {
classMock.when(() -> UtilClass.staticMethod("foo")).thenReturn("bar");
assertEquals("bar", UtilClass.staticMethod("foo"));
}
assertEquals("foo", UtilClass.staticMethod("foo"));
}
The try-with-resource block is used to make the static mock remains temporary, so it's mocked only within that scope.
When not using a try block, make sure to close the scoped mock, once you are done with the assertions.
MockedStatic<UtilClass> classMock = mockStatic(UtilClass.class)
classMock.when(() -> UtilClass.staticMethod("foo")).thenReturn("bar");
assertEquals("bar", UtilClass.staticMethod("foo"));
classMock.close();
Mocking void methods:
When mockStatic
is called on a class, all the static void methods in that class automatically get mocked to doNothing()
.
All methods mention here are not working for me. I built Subversion from source, and I found out, I must run configure with --enable-plaintext-password-storage
to support this feature.
You need scheme, host, path and queryString
@string.Format("{0}://{1}{2}{3}", Context.Request.Scheme, Context.Request.Host, Context.Request.Path, Context.Request.QueryString)
or using new C#6 feature "String interpolation"
@($"{Context.Request.Scheme}://{Context.Request.Host}{Context.Request.Path}{Context.Request.QueryString}")
Big warning on several of the solutions (and your own test) :
When you do : anything | xargs something
xargs will try to fit "as many arguments as possible" after "something", but then you may end up with multiple invocations of "something".
So your attempt: find ... | xargs tar czvf file.tgz may end up overwriting "file.tgz" at each invocation of "tar" by xargs, and you end up with only the last invocation! (the chosen solution uses a GNU -T special parameter to avoid the problem, but not everyone has that GNU tar available)
You could do instead:
find . -type f -print0 | xargs -0 tar -rvf backup.tar
gzip backup.tar
Proof of the problem on cygwin:
$ mkdir test
$ cd test
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs touch
# create the files
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar czvf archive.tgz
# will invoke tar several time as it can'f fit 10000 long filenames into 1
$ tar tzvf archive.tgz | wc -l
60
# in my own machine, I end up with only the 60 last filenames,
# as the last invocation of tar by xargs overwrote the previous one(s)
# proper way to invoke tar: with -r (which append to an existing tar file, whereas c would overwrite it)
# caveat: you can't have it compressed (you can't add to a compressed archive)
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar rvf archive.tar #-r, and without z
$ gzip archive.tar
$ tar tzvf archive.tar.gz | wc -l
10000
# we have all our files, despite xargs making several invocations of the tar command
Note: that behavior of xargs is a well know diccifulty, and it is also why, when someone wants to do :
find .... | xargs grep "regex"
they intead have to write it:
find ..... | xargs grep "regex" /dev/null
That way, even if the last invocation of grep by xargs appends only 1 filename, grep sees at least 2 filenames (as each time it has: /dev/null
, where it won't find anything, and the filename(s)
appended by xargs after it) and thus will always display the file names when something maches "regex". Otherwise you may end up with the last results showing matches without a filename in front.
You can not run/execute an .exe file that is in the users local machine or through a site. The user must first download the exe file and then run the executable file.
So there is no possible way
The following code works only when the EXE is Present in the User's Machine.

After an activity started, restarted (onRestart() happens before onStart()), or paused (onPause()), onResume() called. When the activity is in the state of onResume(), the activity is ready to be used by the app user.
I have studied the activity lifecycle a little bit, and here's my understanding of this topic: If you want to restart the activity (A) at the end of the execution of another, there could be a few different cases.
The other activity (B) has been paused and/or stopped or destroyed, and the activity A possibly had been paused (onPause()), in this case, activity A will call onResume()
The activity B has been paused and/or stopped or destroyed, the activity A possibly had been stopped (onStop()) due to memory thing, in this case, activity A will call onRestart() first, onStart() second, then onResume()
The activity B has been paused and/or stopped or destroyed, the activity A has been destroyed, the programmer can call onStart() manually to start the activity first, then onResume() because when an activity is in the destroyed status the activity has not started, and this happens before the activity being completely removed. If the activity is removed, the activity needs to be created again. Manually calling onStart() I think it's because if the activity not started and it is created, onStart() will be called after onCreate().
If you want to update data, make a data update function and put the function inside the onResume(). Or put a loadData function inside onResume()
It's better to understand the lifecycle with the help of the Activity lifecycle diagram.

I found this happening to me with a broken layout and everything blows up. Relax, it's like that old mistake when you first learned programming C where you forget one semicolon and it generates a hundred errors. Many panic, press all the buttons, and makes things worse.

.This usually happens when you have a broken XML file.

. Build fails silently if they don't match.Use following code to perform if-else conditioning in python: Here, I am checking the length of the string. If the length is less than 3 then do nothing, if more then 3 then I check the last 3 characters. If last 3 characters are "ing" then I add "ly" at the end otherwise I add "ing" at the end.
Code-
if (len(s)<=3):
return s
elif s[-3:]=="ing":
return s+"ly"
else: return s + "ing"
If the input field has a class name formData use this :
$(".formData").val("data")
If the input field has an id attribute name formData use this :
$("#formData").val("data")
If the input name is given use this :
$("input[name='formData']").val("data")
You can also mention the type. Then it will refer to all the inputs of that type and the given class name:
$("input[type='text'].formData").val("data")
I would probably choose Git because I feel it's much more powerful than SVN. There are cheap Code Hosting services available which work just great for me - you don't have to do backups or any maintenance work - GitHub is the most obvious candidate.
That said, I don't know anything regarding the integration of Visual Studio and the different SCM systems. I imagine the integration with SVN to notably better.
You might take advantage of ruby's "splat" or flattening syntax.
This makes overgrown when
clauses — you have about 10 values to test per branch if I understand correctly — a little more readable in my opinion. Additionally, you can modify the values to test at runtime. For example:
honda = ['honda', 'acura', 'civic', 'element', 'fit', ...]
toyota = ['toyota', 'lexus', 'tercel', 'rx', 'yaris', ...]
...
if include_concept_cars
honda += ['ev-ster', 'concept c', 'concept s', ...]
...
end
case car
when *toyota
# Do something for Toyota cars
when *honda
# Do something for Honda cars
...
end
Another common approach would be to use a hash as a dispatch table, with keys for each value of car
and values that are some callable object encapsulating the code you wish to execute.
This is a feature, not a bug.
See http://docs.python.org/howto/unicode.html, specifically the 'unicode type' section.
String y = "hello";
would work (note the double quotes).
char y = 'h'; this will work for chars (note the single quotes)
but the type is the key: '' (single quotes) for one char, "" (double quotes) for string.
Not directly. But you can use extensions such as LESS to help you achieve the same.
Use the DISTINCT operator in MySQL:
SELECT DISTINCT(Date) AS Date FROM buy ORDER BY Date DESC;
It's possible to effectively define a variable that can be used in both the SELECT, WHERE and other clauses.
A subquery doesn't necessarily allow for appropriate binding to the referenced table columns, however OUTER APPLY does.
SELECT A.identifier
, A.name
, vars.MONTH_NO
, TO_NUMBER(TO_CHAR(B.last_update_date, 'YYYYMM')) as UPD_DATE
FROM table_a A
, table_b B ON A.identifier = B.identifier
OUTER APPLY (
SELECT
-- variables
MONTH_NO = TO_NUMBER(DECODE( A.month_no
, 1, 200803
, 2, 200804
, 3, 200805
, 4, 200806

My reputation being too small to comment an answer, here is my feedback concerning roquen answer (using settings on xmlwriter to force the stream to close): it works perfectly and it made me save a lot of time. roquen's example requires some adjustment, here is the code that works on .NET framework 4.8 :
XmlWriterSettings settings = new XmlWriterSettings();
settings.CloseOutput = true;
writer = XmlWriter.Create(stream, settings);
In command prompt type below
set PATH=%PATH%;C:\path\to\php
Where C:\path\to\php is the folder where your php.exe

Step 8 - Select

row and then clickEdit
Step 9 - Click

and then clickBrowse
, then in the next panel which will open you need to select the folder you want in thePath
. For the initial premise of this guide i will add the folderC:\Users\NewFolderInPath
?Note: Replace your PHP installed path(e.g:

There's a simpler way by leveraging the use of bind
and call
methods.
By setting private variables to an object, you can leverage that object's scope.
function TestClass (value) {
// The private value(s)
var _private = {
value: value
};
// `bind` creates a copy of `getValue` when the object is instantiated
this.getValue = TestClass.prototype.getValue.bind(_private);
// Use `call` in another function if the prototype method will possibly change
this.getValueDynamic = function() {
return TestClass.prototype.getValue.call(_private);
};
};
TestClass.prototype.getValue = function() {
return this.value;
};
This method isn't without drawbacks. Since the scope context is effectively being overridden, you don't have access outside of the _private
object. However, it isn't impossible though to still give access to the instance object's scope. You can pass in the object's context (this
) as the second argument to bind
or call
to still have access to it's public values in the prototype function.
function TestClass (value) {
var _private = {
value: value
};
this.message = "Hello, ";
this.getMessage = TestClass.prototype.getMessage.bind(_private, this);
}
TestClass.prototype.getMessage = function(_public) {
// Can still access passed in arguments
// e.g. – test.getValues('foo'), 'foo' is the 2nd argument to the method
console.log([].slice.call(arguments, 1));
return _public.message + this.value;
};
var test = new TestClass("World");
test.getMessage(1, 2, 3); // [1, 2, 3] (console.log)
// => "Hello, World" (return value)
test.message = "Greetings, ";
test.getMessage(); // [] (console.log)
// => "Greetings, World" (return value)
Show Processlist fetches the information from another table. Here is how you can pull the data and look at 'INFO' column which contains the whole query :
select * from INFORMATION_SCHEMA.PROCESSLIST where db = 'somedb';
You can add any condition or ignore based on your requirement.
The output of the query is resulted as :
+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
| ID | USER | HOST | DB | COMMAND | TIME | STATE | INFO |
+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
| 5 | ssss | localhost:41060 | somedb | Sleep | 3 | | NULL |
| 58169 | root | localhost | somedb | Query | 0 | executing | select * from sometable where tblColumnName = 'someName' |
%>%
is similar to pipe in Unix. For example, in
a <- combined_data_set %>% group_by(Outlet_Identifier) %>% tally()
the output of combined_data_set
will go into group_by
and its output will go into tally
, then the final output is assigned to a
.
This gives you handy and easy way to use functions in series without creating variables and storing intermediate values.
No, you can't.
There's no reason why you would need to. This is a one-time operation and so takes only an additional second or two to actually type and execute.
If you're adding columns in your web application this is more indicative of a flaw in your data-model as you shouldn't need to be doing it.
In response to your comment that a comment is a column attribute; it may seem so but behind the scenes Oracle stores this as an attribute of an object.

I assume, I have no knowledge, that this was done in order to only have one system of dealing with comments rather than multiple.

On 64-bit systems the x64 key is:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Most programs are listed there. Look at the keys:
DisplayName
DisplayVersion
Note that the last is not always set!
On 64-bit systems the x86 key (usually with more entries) is:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
You have extra spaces after END;
that cause the heredoc not terminated.
Here is example code for usage of java's built-in FIFO queue:
public static void main(String[] args) {
Queue<Integer> myQ = new LinkedList<Integer>();
myQ.add(1);
myQ.add(6);
myQ.add(3);
System.out.println(myQ); // 1 6 3
int first = myQ.poll(); // retrieve and remove the first element
System.out.println(first); // 1
System.out.println(myQ); // 6 3
}
The following will only work if you do not have spaces in your input:
xargs -L 1
xargs --max-lines=1 # synonym for the -L option
from the man page:
-L max-lines
Use at most max-lines nonblank input lines per command line.
Trailing blanks cause an input line to be logically continued on
the next input line. Implies -x.
I had similar issue. Earlier I was using Maven 3 to build the project. After switching to maven 2 , I had the above error.
Solved it by switching to Maven 3.
It depends what is a use of those tables, but you might consider putting trigger on original table on insert and update. When insert or update is done, update the second table based on only one item from the original table. It will be quicker.
This is when you're working with a FileList
Object:
onChange={(event: React.ChangeEvent<HTMLInputElement>): void => {
const fileListObj: FileList | null = event.target.files;
if (Object.keys(fileListObj as Object).length > 3) {
alert('Only three images pleaseeeee :)');
} else {
// Do something
}
return;
}}
C Commandment #3:

Works for me! GNU bash, version 4.3.11(1)-release (x86_64-pc-linux-gnu)
Use max width and max height. It will keep the aspect ratio
#container img
{
max-width: 250px;
max-height: 250px;
}
You need to find what your local network's IP of that computer is. Then other people can access to your site by that IP.
You can find your local network's IP by go to Command Prompt or press Windows + R then type in ipconfig
. It will give out some information and your local IP should look like 192.168.1.x.
This question wasn't asking explicitly about Docker, but I received the same error when I had a pom.xml file that was targeting 1.9...
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.9</maven.compiler.source>
<maven.compiler.target>1.9</maven.compiler.target>
</properties>
... but then tried to run tests against a Docker container by specifying "maven" by itself.
docker run -t --rm -v m2_repository:/root/.m2/repository -v $(pwd):/work -w /work maven mvn -e test
For me, the fix was to target the exact version I needed.
docker run -t --rm -v m2_repository:/root/.m2/repository -v $(pwd):/work -w /work maven:3.5.2-jdk-9 mvn test

This is a mix of the two previous answers:
PreparedStatement ps = c.prepareStatement("INSERT INTO employees VALUES (?, ?)");
ps.setString(1, "John");
ps.setString(2,"Doe");
ps.addBatch();
ps.clearParameters();
ps.setString(1, "Dave");
ps.setString(2,"Smith");
ps.addBatch();
ps.clearParameters();
int[] results = ps.executeBatch();
Hmm, best way is to use this command:
du -h -x / | sort -hr >> /home/log_size.txt
Then you will be able to get all sizes folders over all your server. Easy to help to you to find the biggest sizes.
Use:
/*/ITEM[starts-with(REVENUE_YEAR,'2552')]/REGION
Note: Unless your host language can't handle element instance as result, do not use text nodes specially in mixed content data model. Do not start expressions with //
operator when the schema is well known.
The asterisk (*) means "zero or more of the previous item".
If you want to match any single character use
sed -i 's/string-./string-0/g' file.txt
If you want to match any string (i.e. any single character zero or more times) use
sed -i 's/string-.*/string-0/g' file.txt
To change color of a cell:
$(document).on('click', '#table tbody td', function (event) {
var selected = $(this).hasClass("obstacle");
$("#table tbody td").removeClass("obstacle");
if (!selected)
$(this).addClass("obstacle");
});
i downloaded paramiko full source code from pypi and did
python setup.py install
it worked flawlessly
all default pythondev / openssl /libffi packages are already present in rhel.
downloading rpms have rpm mismatch and more trouble
To piggyback on rkj's answer, to avoid endless prompts (and force the command recursively), enter the following into the command line, within the project folder:
$ rm -rf .git
Or to delete .gitignore and .gitmodules if any (via @aragaer):
$ rm -rf .git*
Then from the same ex-repository folder, to see if hidden folder .git is still there:
$ ls -lah
If it's not, then congratulations, you've deleted your local git repo, but not a remote one if you had it. You can delete GitHub repo on their site (github.com).
To view hidden folders in Finder (Mac OS X) execute these two commands in your terminal window:
defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder
