In your code:
while(fscanf(fp,"%s %c",item,&status) == 1)
why 1 and not 2? The scanf functions return the number of objects read.
Using CPython, your file will be closed immediately after the line is executed, because the file object is immediately garbage collected. There are two drawbacks, though:
In Python implementations different from CPython, the file often isn't immediately closed, but rather at a later time, beyond your control.
In Python 3.2 or above, this will throw a ResourceWarning
, if enabled.
Better to invest one additional line:
with open('pagehead.section.htm','r') as f:
output = f.read()
This will ensure that the file is correctly closed under all circumstances.
Since Node v11.0.0 fs promises are available natively without promisify
:
const fs = require('fs').promises;
async function loadMonoCounter() {
const data = await fs.readFile("monolitic.txt", "binary");
return new Buffer(data);
}
Take a look at this video
All what you have to do is to select your file (assuming it's same simple form of txt file), then drag it to the project in Eclipse and then drop it there. Choose Copy instead of Link as it's more flexible. That's it - I just tried that.
Latest and greatest way to do this:
Node supports file and buffer operations with the base64
encoding:
const fs = require('fs');
const contents = fs.readFileSync('/path/to/file.jpg', {encoding: 'base64'});
Or using the new promises API:
const fs = require('fs').promises;
const contents = await fs.readFile('/path/to/file.jpg', {encoding: 'base64'});
When in doubt, read the documentation:
filename = "C:\Temp\vblist.txt"
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)
Do Until f.AtEndOfStream
WScript.Echo f.ReadLine
Loop
f.Close
This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.
var fs = require("fs");
var filename = "./index.html";
function start(resp) {
fs.readFile(filename, "utf8", function(err, data) {
if (err) {
// may be filename does not exists?
resp.writeHead(404, {
'Content-Type' : 'text/html'
});
// log this error into browser
resp.write(err.toString());
resp.end();
} else {
resp.writeHead(200, {
"Content-Type": "text/html"
});
resp.write(data.toString());
resp.end();
}
});
}
maybe map
, but since you don't want to make a list, you can write your own...
def call_for_all(f, seq):
for i in seq:
f(i)
then you can do:
call_for_all(lamda x: x.start(), all)
call_for_all(lamda x: x.stop(), all)
by the way, all is a built in function, don't overwrite it ;-)
I was looking for a different solution.
Error logs, by default, before any configuration is set, on my system (x86 Arch Linux), was found in:
/var/log/nginx/error.log
In my case reload() doesn't work because the asp.net controls behavior. So, to solve this issue I've used this approach, despite seems a work around.
self.clear = function () {
//location.reload(true); Doesn't work to IE neither Firefox;
//also, hash tags must be removed or no postback will occur.
window.location.href = window.location.href.replace(/#.*$/, '');
};
Add below alias to your ~/.bash_profile
, then run, source ~/.bash_profile
; now anytime you need to see the updated files in the last commit, run, showfiles
from your git repository.
alias showfiles='git show --pretty="format:" --name-only'
Let's say that you have class A
that contain class B
When you want to call some function of class B
outside class A
you will simply obtain a pointer to this class and you can do whatever you want and it will also change context of class B
in your class A
But be careful with dynamic object
Another way to think about Return-Path
vs Reply-To
is to compare it to snail mail.
When you send an envelope in the mail, you specify a return address. If the recipient does not exist or refuses your mail, the postmaster returns the envelope back to the return address. For email, the return address is the Return-Path
.
Inside of the envelope might be a letter and inside of the letter it may direct the recipient to "Send correspondence to example address". For email, the example address is the Reply-To
.
In essence, a Postage Return Address is comparable to SMTP's Return-Path
header and SMTP's Reply-To
header is similar to the replying instructions contained in a letter.
I think all these answers are missing the question. The problem was to "Round UP", not just "Round". It is my understanding that Round Up means that ANY fractional value about a whole digit rounds up to the next WHOLE digit. ie: 48.0000000 = 48 but 25.00001 = 26. Is this not the definition of rounding up? (or have my past 60 years in accounting been misplaced?
To round down to the second:
dateTime.AddTicks(-dateTime.Ticks % TimeSpan.TicksPerSecond)
Replace with TicksPerMinute
to round down to the minute.
If your code is performance sensitive, be cautious about
new DateTime(date.Year, date.Month, date.Day, date.Hour, date.Minute, date.Second)
My app was spending 12% of CPU time in System.DateTime.GetDatePart.
In Bootstrap 3.3.x make sure you use the scrollspy JavaScript capability to track active elements. It's easy to include it in your HTML. Just do the following:
<body data-spy="scroll" data-target="Id or class of the element you want to track">
In most cases I usually track active elements on my navbar, so I do the following:
<body data-spy="scroll" data-target=".navbar-fixed-top" >
Now in your CSS you can target .navbar-fixed-top .active a
:
.navbar-fixed-top .active a {
// Put in some styling
}
This should work if you are tracking active li elements in your top fixed navigation bar.
Have a look at $_SERVER['REQUEST_URI']
, i.e.
$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
(Note that the double quoted string syntax is perfectly correct)
If you want to support both HTTP and HTTPS, you can use
$actual_link = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
Editor's note: using this code has security implications. The client can set HTTP_HOST and REQUEST_URI to any arbitrary value it wants.

const canvas = document.querySelector('canvas');
const ctx = canvas.getContext('2d');
ctx.fillStyle = "#FF0000";
ctx.fillRect(0, 0, canvas.width, canvas.height);

To add some more detail about the overloading that you asked about in your comment after another answer, here is a summary. The comments in the ApiController
show which action will be called with each GET
query:
public class ValuesController : ApiController
{
// EXPLANATION: See the view for the buttons which call these WebApi actions. For WebApi controllers,
// there can only be one action for a given HTTP verb (GET, POST, etc) which has the same method signature, (even if the param names differ) so
// you can't have Get(string height) and Get(string width), but you can have Get(int height) and Get(string width).
// It isn't a particularly good idea to do that, but it is true. The key names in the query string must match the
// parameter names in the action, and the match is NOT case sensitive. This demo app allows you to test each of these
// rules, as follows:
//
// When you send an HTTP GET request with no parameters (/api/values) then the Get() action will be called.
// When you send an HTTP GET request with a height parameter (/api/values?height=5) then the Get(int height) action will be called.
// When you send an HTTP GET request with a width parameter (/api/values?width=8) then the Get(string width) action will be called.
// When you send an HTTP GET request with height and width parameters (/api/values?height=3&width=7) then the
// Get(string height, string width) action will be called.
// When you send an HTTP GET request with a depth parameter (/api/values?depth=2) then the Get() action will be called
// and the depth parameter will be obtained from Request.GetQueryNameValuePairs().
// When you send an HTTP GET request with height and depth parameters (/api/values?height=4&depth=5) then the Get(int height)
// action will be called, and the depth parameter would need to be obtained from Request.GetQueryNameValuePairs().
// When you send an HTTP GET request with width and depth parameters (/api/values?width=3&depth=5) then the Get(string width)
// action will be called, and the depth parameter would need to be obtained from Request.GetQueryNameValuePairs().
// When you send an HTTP GET request with height, width and depth parameters (/api/values?height=7&width=2&depth=9) then the
// Get(string height, string width) action will be called, and the depth parameter would need to be obtained from
// Request.GetQueryNameValuePairs().
// When you send an HTTP GET request with a width parameter, but with the first letter of the parameter capitalized (/api/values?Width=8)
// then the Get(string width) action will be called because the case does NOT matter.
// NOTE: If you were to uncomment the Get(string height) action below, then you would get an error about there already being
// a member named Get with the same parameter types. The same goes for Get(int id).
//
// ANOTHER NOTE: Using the nullable operator (e.g. string? paramName) you can make optional parameters. It would work better to
// demonstrate this in another ApiController, since using nullable params and having a lot of signatures is a recipe
// for confusion.
// GET api/values
public IEnumerable<string> Get()
{
return Request.GetQueryNameValuePairs().Select(pair => "Get() => " + pair.Key + ": " + pair.Value);
//return new string[] { "value1", "value2" };
}
//// GET api/values/5
//public IEnumerable<string> Get(int id)
//{
// return new string[] { "Get(height) => height: " + id };
//}
// GET api/values?height=5
public IEnumerable<string> Get(int height) // int id)
{
return new string[] { "Get(height) => height: " + height };
}
// GET api/values?height=3
public IEnumerable<string> Get(string height)
{
return new string[] { "Get(height) => height: " + height };
}
//// GET api/values?width=3
//public IEnumerable<string> Get(string width)
//{
// return new string[] { "Get(width) => width: " + width };
//}
// GET api/values?height=4&width=3
public IEnumerable<string> Get(string height, string width)
{
return new string[] { "Get(height, width) => height: " + height + ", width: " + width };
}
}
You would only need a single route for this, in case you wondered:
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
and you could test it all with this MVC view, or something simlar. Yes, I know you aren't supposed to mix JavaScript with markup and I'm not using bootstrap like you would normally, but this is for demo purposes only.

I believe you also have to use .detach()
. I had to convert my Tensor to a numpy array on Colab which uses CUDA and GPU. I did it like the following:
# this is just my embedding matrix which is a Torch tensor object
embedding = learn.model.u_weight
embedding_list = list(range(0, 64382))
input = torch.cuda.LongTensor(embedding_list)
tensor_array = embedding(input)
# the output of the line below is a numpy array
tensor_array.cpu().detach().numpy()
Well, your code is not reproducible so we will never know for sure, but this is what help('break')
says:
break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop.
So yes, break
only breaks the current loop. You can also see it in action with e.g.:
for (i in 1:10)
{
for (j in 1:10)
{
for (k in 1:10)
{
cat(i," ",j," ",k,"\n")
if (k ==5) break
}
}
}

I know this is super old, but comes up whenever I google this issue. You can unprotect the range as given in the above cells and then add data validation to the unprotected cells to reference something outrageous like "423fdgfdsg3254fer" and then if users try to edit any those cells, they will be unable to, but you're sorting and filtering will now work.
In (c++ like) pseudocode these two are what I used in industrial image processing applications that had to process images from a set of externally triggered camera's. Variations in "frame rate" had a different source (slower or faster production on the belt) but the problem is the same. (I assume that you have a simple timer.peek() call that gives you something like the nr of msec (nsec?) since application start or the last call)
Solution 1: fast but not updated every frame
do while (1)
{
ProcessImage(frame)
if (frame.framenumber%poll_interval==0)
{
new_time=timer.peek()
framerate=poll_interval/(new_time - last_time)
last_time=new_time
}
}
Solution 2: updated every frame, requires more memory and CPU
do while (1)
{
ProcessImage(frame)
new_time=timer.peek()
delta=new_time - last_time
last_time = new_time
total_time += delta
delta_history.push(delta)
framerate= delta_history.length() / total_time
while (delta_history.length() > avg_interval)
{
oldest_delta = delta_history.pop()
total_time -= oldest_delta
}
}
If you're using ASP.NET MVC you might also need to remove the HandleErrorAttribute from the Global.asax.cs file:
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}
Simple answer - whenever your SQL is not altering data, and you have a query that might interfere with other activity (via locking).
It's worth considering for any queries used for reports, especially if the query takes more than, say, 1 second.
It's especially useful if you have OLAP-type reports you're running against an OLTP database.
The first question to ask, though, is "why am I worrying about this?" ln my experience, fudging the default locking behavior often takes place when someone is in "try anything" mode and this is one case where unexpected consequences are not unlikely. Too often it's a case of premature optimization and can too easily get left embedded in an application "just in case." It's important to understand why you're doing it, what problem it solves, and whether you actually have the problem.
It's tricky to handle mixed line endings properly. As we know, the line termination characters can be "Line Feed" (ASCII 10, \n
, \x0A
, \u000A
), "Carriage Return" (ASCII 13, \r
, \x0D
, \u000D
), or some combination of them. Going back to DOS, Windows uses the two-character sequence CR-LF \u000D\u000A
, so this combination should only emit a single line. Unix uses a single \u000A
, and very old Macs used a single \u000D
character. The standard way to treat arbitrary mixtures of these characters within a single text file is as follows:
\u000D\u000A
) then these two together skip just one line.String.Empty
is the only input that returns no lines (any character entails at least one line)The preceding rule describes the behavior of StringReader.ReadLine and related functions, and the function shown below produces identical results. It is an efficient C# line breaking function that dutifully implements these guidelines to correctly handle any arbitrary sequence or combination of CR/LF. The enumerated lines do not contain any CR/LF characters. Empty lines are preserved and returned as String.Empty
.
/// <summary>
/// Enumerates the text lines from the string.
/// ? Mixed CR-LF scenarios are handled correctly
/// ? String.Empty is returned for each empty line
/// ? No returned string ever contains CR or LF
/// </summary>
public static IEnumerable<String> Lines(this String s)
{
int j = 0, c, i;
char ch;
if ((c = s.Length) > 0)
do
{
for (i = j; (ch = s[j]) != '\r' && ch != '\n' && ++j < c;)
;
yield return s.Substring(i, j - i);
}
while (++j < c && (ch != '\r' || s[j] != '\n' || ++j < c));
}
Note: If you don't mind the overhead of creating a StringReader
instance on each call, you can use the following C# 7 code instead. As noted, while the example above may be slightly more efficient, both of these functions produce the exact same results.
public static IEnumerable<String> Lines(this String s)
{
using (var tr = new StringReader(s))
while (tr.ReadLine() is String L)
yield return L;
}
this is my favorite hack (not sure it should work). It refer an element that is not yet displayed, and it works pretty well

So basically you can do this:
fs.readFile(path.resolve(__dirname, 'settings.json'), 'UTF-8', callback);
Use resolve() instead of concatenating with '/' or '\' else you will run into cross-platform issues.
Note: __dirname is the local path of the module or included script. If you are writing a plugin which needs to know the path of the main script it is:
require.main.filename
or, to just get the folder name:
require('path').dirname(require.main.filename)
What browser are you testing in?
What DOCType have you set?
How exactly are you declaring your CSS?
Are you sure you haven't missed a ;

import re

supper=''.join(re.findall(r'[A-Z]',s))
print slower, supper
Prints:

Or you can use a list comprehension / generator expression:

supper=''.join(c for c in s if c.isupper())
print slower, supper
Prints:

Both lines are in fact correct but do subtly different things.
The first line creates a new object on the stack by calling a constructor of the format Thing(const char*)
.
The second one is a bit more complex. It essentially does the following
Thing
using the constructor Thing(const char*)
Thing
using the constructor Thing(const Thing&)
~Thing()
on the object created in step #1Add
@Produces({"image/jpeg,image/png"})
to
@POST
@Path("/pdf")
@Consumes({ MediaType.MULTIPART_FORM_DATA })
@Produces({"image/jpeg,image/png"})
//@Produces("text/plain")
public Response uploadPdfFile(@FormDataParam("file") InputStream fileInputStream,@FormDataParam("file") FormDataContentDisposition fileMetaData) throws Exception {
...
}
Just change your syntax ever so slightly:
CASE WHEN STATE = 2 AND RetailerProcessType = 1 THEN '"AUTHORISED"'
WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
WHEN STATE = 2 AND RetailerProcessType = 2 THEN '"AUTHORISED"'
ELSE '"DECLINED"'
END
If you don't put the field expression before the CASE
statement, you can put pretty much any fields and comparisons in there that you want. It's a more flexible method but has slightly more verbose syntax.
if you have this error :
configure: error: Either a previously installed pkg-config or "glib-2.0 >= 2.16" could not be found. Please set GLIB_CFLAGS and GLIB_LIBS to the correct values or pass --with-internal-glib to configure to use the bundled copy.
Instead of do this command :
$ ./configure && make install
Do that :
./configure --with-internal-glib && make install
You can use element.getBoundingClientRect()
to retrieve element position relative to the viewport.
Then use document.documentElement.scrollTop
to calculate the viewport offset.
The sum of the two will give the element position relative to the document:
element.getBoundingClientRect().top + document.documentElement.scrollTop
The answers above check if a filesystem contains a path that is a file or directory. But it doesn't identify if a given path alone is a file or directory.
The answer is to identify directory-based paths using "/." like --> "/c/dos/run/." <-- trailing period.
Like a path of a directory or file that has not been written yet. Or a path from a different computer. Or a path where both a file and directory of the same name exists.
// /tmp/
// |- dozen.path
// |- dozen.path/.
// |- eggs.txt
//
// "/tmp/dozen.path" !== "/tmp/dozen.path/"
//
// Very few fs allow this. But still. Don't trust the filesystem alone!
// Converts the non-standard "path-ends-in-slash" to the standard "path-is-identified-by current "." or previous ".." directory symbol.
function tryGetPath(pathItem) {
const isPosix = pathItem.includes("/");
if ((isPosix && pathItem.endsWith("/")) ||
(!isPosix && pathItem.endsWith("\\"))) {
pathItem = pathItem + ".";
}
return pathItem;
}
// If a path ends with a current directory identifier, it is a path! /c/dos/run/. and c:\dos\run\.
function isDirectory(pathItem) {
const isPosix = pathItem.includes("/");
if (pathItem === "." || pathItem ==- "..") {
pathItem = (isPosix ? "./" : ".\\") + pathItem;
}
return (isPosix ? pathItem.endsWith("/.") || pathItem.endsWith("/..") : pathItem.endsWith("\\.") || pathItem.endsWith("\\.."));
}
// If a path is not a directory, and it isn't empty, it must be a file
function isFile(pathItem) {
if (pathItem === "") {
return false;
}
return !isDirectory(pathItem);
}

Last thought: Why even hit the filesystem?
Most answers are duplicates, it might be useful to group them. Basically two simple options have been proposed.
The first option has 4 different aliases, some of which are quite short :
EXPLAIN db_name.table_name;
DESCRIBE db_name.table_name;
SHOW FIELDS FROM db_name.table_name;
SHOW COLUMNS FROM db_name.table_name;
(NB : as an alternative to db_name.table_name
, one can use a second FROM
: db_name FROM table_name
).
This gives something like :
+------------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+------------------+--------------+------+-----+---------+-------+
| product_id | int(11) | NO | PRI | NULL | |
| name | varchar(255) | NO | MUL | NULL | |
| description | text | NO | | NULL | |
| meta_title | varchar(255) | NO | | NULL | |
+------------------+--------------+------+-----+---------+-------+
The second option is a bit longer :
SELECT
COLUMN_NAME, DATA_TYPE
FROM
INFORMATION_SCHEMA.COLUMNS
WHERE
TABLE_SCHEMA = 'db_name'
AND
TABLE_NAME = 'table_name';
It is also less talkative :
+------------------+-----------+
| column_name | DATA_TYPE |
+------------------+-----------+
| product_id | int |
| name | varchar |
| description | text |
| meta_title | varchar |
+------------------+-----------+
It has the advantage of allowing selection per column, though, using AND COLUMN_NAME = 'column_name'
(or like
).
As already mentioned, the performance is the same. However, user experience isn't necessarily identical. In the first case, you'll fail fast (i.e. after the first error), however if you put the try/catch block inside the loop, you can capture all the errors that would be created for a given call to the method. When parsing an array of values from strings where you expect some formatting errors, there are definitely cases where you'd like to be able to present all the errors to the user so that they don't need to try and fix them one by one.
Having a large Answer table, in and of itself, is not a problem. As long as the indexes and constraints are well defined you should be fine. Your second schema looks good to me.
There is an another mature and actively developed "player" on the javascript linting front - ESLint
:
ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code. In many ways, it is similar to JSLint and JSHint with a few exceptions:
- ESLint uses Esprima for JavaScript parsing.
- ESLint uses an AST to evaluate patterns in code.
- ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime.
What really matters here is that it is extendable via custom plugins/rules. There are already multiple plugins written for different purposes. Among others, there are:
And, of course, you can use your build tool of choice to run ESLint
:
It sounds like the populate method is what your looking for. First make small change to your post schema:
var postSchema = new Schema({
name: String,
postedBy: {type: mongoose.Schema.Types.ObjectId, ref: 'User'},
dateCreated: Date,
comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});
Then make your model:
var Post = mongoose.model('Post', postSchema);
Then, when you make your query, you can populate references like this:
Post.findOne({_id: 123})
.populate('postedBy')
.exec(function(err, post) {
// do stuff with post
});
I faced the same problem in eclipse with tomcat7 with the error javax.servlet cannot be resolved. If I select the server in targeted runtime mode and build project again, the error get's resolved.
It is ok for sure. With just few hundred of entries, it will be fast.
You can add an unique id as as primary key (int autoincrement) ans set your coupon_code as unique. So if you need to do request in other tables it's better to use int than varchar
See if this works for you... In this code, I had 3 2-dimensional arrays, called red,green and blue. Each one was of size [width][height], and each element corresponded to a pixel - I hope this makes sense!
FILE *f;
unsigned char *img = NULL;
int filesize = 54 + 3*w*h; //w is your image width, h is image height, both int
img = (unsigned char *)malloc(3*w*h);
memset(img,0,3*w*h);
for(int i=0; i<w; i++)
{
for(int j=0; j<h; j++)
{
x=i; y=(h-1)-j;
r = red[i][j]*255;
g = green[i][j]*255;
b = blue[i][j]*255;
if (r > 255) r=255;
if (g > 255) g=255;
if (b > 255) b=255;
img[(x+y*w)*3+2] = (unsigned char)(r);
img[(x+y*w)*3+1] = (unsigned char)(g);
img[(x+y*w)*3+0] = (unsigned char)(b);
}
}
unsigned char bmpfileheader[14] = {'B','M', 0,0,0,0, 0,0, 0,0, 54,0,0,0};
unsigned char bmpinfoheader[40] = {40,0,0,0, 0,0,0,0, 0,0,0,0, 1,0, 24,0};

An XML declaration is not required in all XML documents; however XHTML document authors are strongly encouraged to use XML declarations in all their documents. Such a declaration is required when the character encoding of the document is other than the default UTF-8 or UTF-16 and no encoding was determined by a higher-level protocol. Here is an example of an XHTML document. In this example, the XML declaration is included.

First of all, kudos on choosing Chart.js! I'm using it on one of my current projects and I absolutely love it - it does the job perfectly.
Although labels/tooltips are not part of the library yet, you may want to take a look at these three pull requests:
And, as Cracker0dks mentioned, Chart.js uses canvas
for rendering so you may as well just implement your own tooltips by interacting with it directly.
Hope this helps.
The problem is caused by your #grid
having a width:1140px
.
You need to set a min-width:1140px
on the body
.
This will stop the body
from getting smaller than the #grid
. Remove width:100%
as block level elements take up the available width by default. Live example: http://jsfiddle.net/tw16/LX8R3/
html, body{
margin:0;
padding:0;
min-width: 1140px; /* this is the important part*/
}
#grid-container{
background:#f8f8f8 url(../images/grid-container-bg.gif) repeat-x top left;
}
#grid{
width:1140px;
margin:0px auto;

using middlwares
1- create middlware with any name
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\View;
class GlobalData
{
public function handle($request, Closure $next)
{
// edit this section and share what do you want
$site_settings = Setting::all();
View::share('site_settings', $site_settings);
return $next($request);
}
}
2- register your middleware in Kernal.php
protected $routeMiddleware = [
.
...
'globaldata' => GlobalData::class,
]
3-now group your routes with globaldata
middleware
Route::group(['middleware' => ['globaldata']], function () {
// add routes that need to site_settings
}
There are many ways to filter for element ancestors.
if ($elem.closest('.parentClass').length /* > 0*/) {/*...*/}
if ($elem.parents('.parentClass').length /* > 0*/) {/*...*/}
if ($elem.parents().hasClass('parentClass')) {/*...*/}
if ($('.parentClass').has($elem).length /* > 0*/) {/*...*/}
if ($elem.is('.parentClass *')) {/*...*/}
Beware, closest()
method includes element itself while checking for selector.
Alternatively, if you have a unique selector matching the $elem
, e.g #myElem
, you can use:
if ($('.parentClass:has(#myElem)').length /* > 0*/) {/*...*/}
if(document.querySelector('.parentClass #myElem')) {/*...*/}
If you want to match an element depending any of its ancestor class for styling purpose only, just use a CSS rule:
.parentClass #myElem { /* CSS property set */ }
Here are some links that I found on face recognition libraries.

Since Java 8, you can use Math.floorDiv
.
It returns the largest (closest to positive infinity) int
value that is less than or equal to the algebraic quotient.
Some examples:
floorDiv(4, 3) == 1
floorDiv(-4, 3) == -2
Alternatively, the /
operator can be used:
(4 / 3) == 1
(-4 / 3) == -1
References:
There are a couple of things you could look at. Based on your question, it looks like the function owner is different from the table owner.
1) Grants via a role : In order to create stored procedures and functions on another user's objects, you need direct access to the objects (instead of access through a role).
2)
By default, stored procedures and SQL methods execute with the privileges of their owner, not their current user.
If you created a table in Schema A and the function in Schema B, you should take a look at Oracle's Invoker/Definer Rights concepts to understand what might be causing the issue.

I followed below steps to install mcrypt for PHP7.2 using PECL.
apt-get install php-pecl
apt-get install libmcrypt-dev libreadline-dev
pecl install mcrypt-1.0.1
You should add "extension=mcrypt.so" to php.ini
Please comment below if you need any assistance. :-)
IMPORTANT !
According to php.net reference many (all) mcrypt functions have been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged.
MVC doesn't do events. Just put a form and submit button on the page and the method decorated with the HttpPost attribute will process that request.
You might want to read a tutorial or two on how to create views, forms and controllers.
textarea {
border: 0;
overflow: auto; }
less CSS ^ you can't align the text to the bottom unfortunately.
There is no error in the code, but the error is thrown due to the following:
- Please check whether you have given Read-write permission to MS-Access database file.
- The Database file where it is stored (say in Folder1) is read-only..?
suppose you are stored the database (MS-Access file) in read only folder, while running your application the connection is not force-fully opened. Hence change the file permission / its containing folder permission like in C:\Program files
all most all c drive files been set read-only so changing this permission solves this Problem.

To list down the indices
curl -L localhost:9200/_cat/indices
9200

You will likely find all indices starting with logstash-yyyy-mm-dd

You can see all the indices and use
To delete the indices and data trigger following command.
curl -XDELETE localhost:9200/index_name
(Which will remove the data and indices both).

You can also, if you like use socket id to manage your player list like this.
io.on('connection', function(socket){
socket.on('disconnect', function() {
console.log("disconnect")
for(var i = 0; i < onlineplayers.length; i++ ){
if(onlineplayers[i].socket === socket.id){

onlineplayers.splice(i, 1)

var exists = false
for(var i = 0; i < onlineplayers.length; i++ ){
if(onlineplayers[i].code === player.code){
exists = true
}
}

When I need to call another constructor from inside the code (not on the first line), I usually use a helper method like this:
class MyClass {
int field;
MyClass() {
init(0);
}
MyClass(int value) {
if (value<0) {
init(0);
}
else {
init(value);
}
}
void init(int x) {
field = x;
}
}
But most often I try to do it the other way around by calling the more complex constructors from the simpler ones on the first line, to the extent possible. For the above example
class MyClass {
int field;
MyClass(int value) {
if (value<0)
field = 0;
else
field = value;
}
MyClass() {
this(0);
}
}
An extension of juba's method is to use reformulate
, a function which is explicitly designed for such a task.
## Create a formula for a model with a large number of variables:
xnam <- paste("x", 1:25, sep="")
reformulate(xnam, "y")
y ~ x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10 + x11 +
x12 + x13 + x14 + x15 + x16 + x17 + x18 + x19 + x20 + x21 +
x22 + x23 + x24 + x25
For the example in the OP, the easiest solution here would be
# add y variable to data.frame d
d <- cbind(y, d)
reformulate(names(d)[-1], names(d[1]))
y ~ x1 + x2 + x3
or
mod <- lm(reformulate(names(d)[-1], names(d[1])), data=d)
Note that adding the dependent variable to the data.frame in d <- cbind(y, d)
is preferred not only because it allows for the use of reformulate
, but also because it allows for future use of the lm
object in functions like predict
.
You have to create two triggers, but you can move the common code into a procedure and have them both call the procedure.
The only way to remove the ADT plugin from Eclipse is to go to Help > About Eclipse/About ADT > Installation Details
.
Select a plug-in you want to uninstall, then click Uninstall...
button at the bottom.
If you cannot remove ADT from this location, then your best option is probably to start fresh with a clean Eclipse install.

If you want the structure of a particular data table(dataTable1) with column headers (without data) into another data table(dataTable2), you can follow the below code:
DataTable dataTable2 = dataTable1.Clone();
dataTable2.Clear();
Now you can fill dataTable2 according to your condition. :)
First, I think you're calling it the wrong thing. "JSON" stands for "JavaScript Object Notation" - it's just a specification for representing some data in a string that explicitly mimics JavaScript object (and array, string, number and boolean) literals. You're trying to build up a JavaScript object dynamically - so the word you're looking for is "object".
With that pedantry out of the way, I think that you're asking how to set object and array properties.
// make an empty object
var myObject = {};
// set the "list1" property to an array of strings
myObject.list1 = ['1', '2'];
// you can also access properties by string
myObject['list2'] = [];
// accessing arrays is the same, but the keys are numbers
myObject.list2[0] = 'a';
myObject['list2'][1] = 'b';
myObject.list3 = [];
// instead of placing properties at specific indices, you
// can push them on to the end
myObject.list3.push({});
// or unshift them on to the beginning
myObject.list3.unshift({});
myObject.list3[0]['key1'] = 'value1';
myObject.list3[1]['key2'] = 'value2';
myObject.not_a_list = '11';
That code will build up the object that you specified in your question (except that I call it myObject instead of myJSON). For more information on accessing properties, I recommend the Mozilla JavaScript Guide and the book JavaScript: The Good Parts.
One difference is for r+
if the files does not exist, it'll not be created and open fails. But in case of a+
the file will be created if it does not exist.
You can also have a look at the method findText(const QString & text) from QComboBox; it returns the index of the element which contains the given text, (-1 if not found). The advantage of using this method is that you don't need to set the second parameter when you add an item.
Here is a little example :
/* Create the comboBox */
QComboBox *_comboBox = new QComboBox;
/* Create the ComboBox elements list (here we use QString) */
QList<QString> stringsList;
stringsList.append("Text1");
stringsList.append("Text3");
stringsList.append("Text4");
stringsList.append("Text2");
stringsList.append("Text5");
/* Populate the comboBox */
_comboBox->addItems(stringsList);
/* Create the label */
QLabel *label = new QLabel;
/* Search for "Text2" text */
int index = _comboBox->findText("Text2");
if( index == -1 )
label->setText("Text2 not found !");
else
label->setText(QString("Text2's index is ")
.append(QString::number(_comboBox->findText("Text2"))));
/* setup layout */
QVBoxLayout *layout = new QVBoxLayout(this);
layout->addWidget(_comboBox);
layout->addWidget(label);
public class User : List<UserData>
{
public int id { get; set; }
public string screen_name { get; set; }
}
string json = client.DownloadString(url);
JavaScriptSerializer serializer = new JavaScriptSerializer();
var Data = serializer.Deserialize<List<UserData>>(json);
Here is another simple way.
var es, log, logFile;
es = require('event-stream');
log = require('gulp-util').log;
logFile = function(es) {
return es.map(function(file, cb) {
log(file.path);
return cb();
});
};
gulp.task("do", function() {
return gulp.src('./examples/*.html')
.pipe(logFile(es))
.pipe(gulp.dest('./build'));
});
You don't need to replace it with anything. The setting magic_quotes_runtime
is removed in PHP6 so the function call is unneeded. If you want to maintain backwards compatibility it may be wise to wrap it in a if statement checking phpversion using version_compare
Click the arrow in the screenshot and find the bash with already running Django server. You were getting the message because your server was already running and you tried to start the server again.

Use Do...Loop with Until keyword
num=0
Do Until //certain_condition_to_break_loop
num=num+1
Loop
This loop will continue to execute, Until the condition becomes true
While...Wend is the old syntax and does not provide feature to break loop! Prefer do while loops
For me this solution works:

There is an interesting project on github called Excel Builder (.js)
that offers a client-side way of downloading Excel xlsx files and includes options for formatting the Excel spreadsheet.
https://github.com/stephenliberty/excel-builder.js
You may encounter both browser and Excel compatibility issues using this library, but under the right conditions, it may be quite useful.
Another github project with less Excel options but less worries about Excel compatibility issues can be found here: ExcellentExport.js

If you are using AngularJS, there is ng-csv:
a "Simple directive that turns arrays and objects into downloadable CSV files".
Below is an example:
Comparisons of $x with PHP functions
Expression gettype() empty() is_null() isset() boolean : if($x)
$x = ""; string TRUE FALSE TRUE FALSE
$x = null; NULL TRUE TRUE FALSE FALSE
var $x; NULL TRUE TRUE FALSE FALSE
$x is undefined NULL TRUE TRUE FALSE FALSE
$x = array(); array TRUE FALSE TRUE FALSE
$x = false; boolean TRUE FALSE TRUE FALSE
$x = true; boolean FALSE FALSE TRUE TRUE
$x = 1; integer FALSE FALSE TRUE TRUE
$x = 42; integer FALSE FALSE TRUE TRUE
$x = 0; integer TRUE FALSE TRUE FALSE
$x = -1; integer FALSE FALSE TRUE TRUE
$x = "1"; string FALSE FALSE TRUE TRUE
$x = "0"; string TRUE FALSE TRUE FALSE
$x = "-1"; string FALSE FALSE TRUE TRUE
$x = "php"; string FALSE FALSE TRUE TRUE
$x = "true"; string FALSE FALSE TRUE TRUE
$x = "false"; string FALSE FALSE TRUE TRUE
Please see this for more reference of type comparisons in PHP. It should give you a clear understanding.
you'll probably want to look into jquery-ui dialog. it's highly customizable and can be made to work exactly like lightbox/fancybox and supports everything you would need for a contact form from a regular link.
there is even an example with a form.
kwargs
in **kwargs
is just variable name. You can very well have **anyVariableName
kwargs
stands for "keyword arguments". But I feel they should better be called as "named arguments", as these are simply arguments passed along with names (I dont find any significance to the word "keyword" in the term "keyword arguments". I guess "keyword" usually means words reserved by programming language and hence not to be used by the programmer for variable names. No such thing is happening here in case of kwargs.). So we give names
param1
and param2
to two parameter values passed to the function as follows: func(param1="val1",param2="val2")
, instead of passing only values: func(val1,val2)
. Thus, I feel they should be appropriately called "arbitrary number of named arguments" as we can specify any number of these parameters (that is, arguments) if func
has signature func(**kwargs)
So being said that let me explain "named arguments" first and then "arbitrary number of named arguments" kwargs
.
Named arguments
Example
def function1(param1,param2="arg2",param3="arg3"):
print("\n"+str(param1)+" "+str(param2)+" "+str(param3)+"\n")
function1(1) #1 arg2 arg3 #1 positional arg
function1(param1=1) #1 arg2 arg3 #1 named arg
function1(1,param2=2) #1 2 arg3 #1 positional arg, 1 named arg
function1(param1=1,param2=2) #1 2 arg3 #2 named args
function1(param2=2, param1=1) #1 2 arg3 #2 named args out of order
function1(1, param3=3, param2=2) #1 2 3 #
#function1() #invalid: required argument missing
#function1(param2=2,1) #invalid: SyntaxError: non-keyword arg after keyword arg
#function1(1,param1=11) #invalid: TypeError: function1() got multiple values for argument 'param1'
#function1(param4=4) #invalid: TypeError: function1() got an unexpected keyword argument 'param4'
Arbitrary number of named arguments kwargs
Example
def function2(param1, *tupleParams, param2, param3, **dictionaryParams):
print("param1: "+ param1)
print("param2: "+ param2)
print("param3: "+ param3)
print("custom tuple params","-"*10)
for p in tupleParams:
print(str(p) + ",")
print("custom named params","-"*10)
for k,v in dictionaryParams.items():
print(str(k)+":"+str(v))
function2("arg1",
"custom param1",
"custom param2",
"custom param3",
param3="arg3",
param2="arg2",
customNamedParam1 = "val1",
customNamedParam2 = "val2"
)
# Output
#
#param1: arg1
#param2: arg2
#param3: arg3
#custom tuple params ----------
#custom param1,
#custom param2,
#custom param3,
#custom named params ----------
#customNamedParam2:val2
#customNamedParam1:val1
Passing tuple and dict variables for custom args
To finish it up, let me also note that we can pass
Thus the same above call can be made as follows:
tupleCustomArgs = ("custom param1", "custom param2", "custom param3")
dictCustomNamedArgs = {"customNamedParam1":"val1", "customNamedParam2":"val2"}
function2("arg1",
*tupleCustomArgs, #note *
param3="arg3",
param2="arg2",
**dictCustomNamedArgs #note **
)
Finally note *
and **
in function calls above. If we omit them, we may get ill results.
Omitting *
in tuple args:
function2("arg1",
tupleCustomArgs, #omitting *
param3="arg3",
param2="arg2",
**dictCustomNamedArgs
)
prints
param1: arg1
param2: arg2
param3: arg3
custom tuple params ----------
('custom param1', 'custom param2', 'custom param3'),
custom named params ----------
customNamedParam2:val2
customNamedParam1:val1
Above tuple ('custom param1', 'custom param2', 'custom param3')
is printed as is.
Omitting dict
args:
function2("arg1",
*tupleCustomArgs,
param3="arg3",
param2="arg2",
dictCustomNamedArgs #omitting **
)
gives
dictCustomNamedArgs

After reading some issues reported on the GitHub repository, I found the solution.
In order to update the angular-cli package installed globally in your system, you need to run:
npm uninstall -g @angular-cli
npm install -g @angular/cli@latest
Depending on your system, you may need to prefix the above commands with sudo
.
Also, most likely you want to also update your local project version, because inside your project directory it will be selected with higher priority than the global one:
rm -rf node_modules
npm uninstall --save-dev @angular-cli
npm install --save-dev @angular/cli@latest
npm install
thanks grizzm0 for pointing this out on GitHub.
After updating your CLI, you probably want to update your Angular version too.
Note: if you are updating to Angular CLI 6+ from an older version, you might need to read this.
Edit: In addition, if you were still on a 1.x version of the cli, you need to convert your angular-cli.json
to angular.json
, which you can do with the following command:
ng update @angular/cli --from=1.7.4 --migrate-only
(check this for more details).
To open in a new windows with dimensions and everything, you will need to call a JavaScript function, as target="_blank" won't let you adjust sizes. An example would be:
<a href="http://www.facebook.com/sharer" onclick="window.open(this.href, 'mywin',
'left=20,top=20,width=500,height=500,toolbar=1,resizable=0'); return false;" >Share this</a>
Hope this helps you.
If you actually start a new thread, that thread will terminate when the method finishes:
Thread thread = new Thread(SecondFoo);
thread.Start();
Now SecondFoo
will be called in the new thread, and the thread will terminate when it completes.
Did you actually mean that you wanted the thread to terminate when the method in the calling thread completes?
EDIT: Note that starting a thread is a reasonably expensive operation. Do you definitely need a brand new thread rather than using a threadpool thread? Consider using ThreadPool.QueueUserWorkItem
or (preferrably, if you're using .NET 4) TaskFactory.StartNew
.
The Problem is with your code formatting,
inorder to use strtotime()
You should replace '06/Oct/2011:19:00:02'
with 06/10/2011 19:00:02
and date('d/M/Y:H:i:s', $date);
with date('d/M/Y H:i:s', $date);
. Note the spaces in between.
So the final code looks like this
$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);
I came across this thread while working on my understanding of Cython. My extension to the original question might be of use to others working at the C / Cython interface. So this is the extension of the original question: how do I return a string from a C function, making it available to Cython & thus to Python?
For those not familiar with it, Cython allows you to statically type Python code that you need to speed up. So the process is, enjoy writing Python :), find its a bit slow somewhere, profile it, calve off a function or two and cythonize them. Wow. Close to C speed (it compiles to C) Fixed. Yay. The other use is importing C functions or libraries into Python as done here.
This will print a string and return the same or another string to Python. There are 3 files, the c file c_hello.c, the cython file sayhello.pyx, and the cython setup file sayhello.pyx. When they are compiled using python setup.py build_ext --inplace
they generate a shared library file that can be imported into python or ipython and the function sayhello.hello run.
c_hello.c
#include <stdio.h>
char *c_hello() {
char *mystr = "Hello World!\n";
return mystr;
// return "this string"; // alterative
}
sayhello.pyx
cdef extern from "c_hello.c":
cdef char* c_hello()
def hello():
return c_hello()
setup.py
from setuptools import setup
from setuptools.extension import Extension
from Cython.Distutils import build_ext
from Cython.Build import cythonize
ext_modules = cythonize([Extension("sayhello", ["sayhello.pyx"])])
setup(
name = 'Hello world app',
cmdclass = {'build_ext': build_ext},
ext_modules = ext_modules
)
I do the same task like this.
//in MessageHeader
private void SetValuesDefault()
{
MessageHeader header = this;
Framework.ObjectPropertyHelper.SetPropertiesToDefault<MessageHeader>(this);
}
//in ObjectPropertyHelper
public static void SetPropertiesToDefault<T>(T obj)
{
Type objectType = typeof(T);
System.Reflection.PropertyInfo [] props = objectType.GetProperties();
foreach (System.Reflection.PropertyInfo property in props)
{
if (property.CanWrite)
{
string propertyName = property.Name;
Type propertyType = property.PropertyType;
object value = TypeHelper.DefaultForType(propertyType);
property.SetValue(obj, value, null);
}
}
}
//in TypeHelper
public static object DefaultForType(Type targetType)
{
return targetType.IsValueType ? Activator.CreateInstance(targetType) : null;
}
use ONLY
function init() {
about = document.getElementById("about");
about.style.color = 'blue';
}
.innerHTML()
sets or gets the HTML syntax describing the element's descendants., All you need is an object here.
Trying to use a dispatch_semaphore
. It should look something like this:
dispatch_semaphore_t sema = dispatch_semaphore_create(0);
[object runSomeLongOperationAndDo:^{
STAssert…
dispatch_semaphore_signal(sema);
}];
if (![NSThread isMainThread]) {
dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
} else {
while (dispatch_semaphore_wait(sema, DISPATCH_TIME_NOW)) {
[[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate dateWithTimeIntervalSinceNow:0]];
}
}
This should behave correctly even if runSomeLongOperationAndDo:
decides that the operation isn't actually long enough to merit threading and runs synchronously instead.
You have to use the jquery attribute selector. You can read more here:
http://api.jquery.com/attribute-equals-selector/
In your case it should be:
$('input[name="btnName"]')
C++20 std::format
options <
, ^
and >
According to https://en.cppreference.com/w/cpp/utility/format/formatter#Standard_format_specification the following should hold:
// left: "42 "
std::cout << std::format("{:<6}", 42);
// right: " 42"
std::cout << std::format("{:>6}", 42);
// center: " 42 "
std::cout << std::format("{:^6}", 42);
More information at: std::string formatting like sprintf
It's working with this code:
Scanner input = new Scanner(System.in);
System.out.println("Enter Name : ");
String name = input.next().toString();
System.out.println("Enter Phone # : ");
String phone = input.next().toString();

Put everything in a script and run it via cron (scheduler). Exporting objects can be tricky when advanced features are used. Don't be surprised if you need to add some more exceptions to the above code.
Here is a sample using pysftp and a private key.
import pysftp
def upload_file(file_path):
private_key = "~/.ssh/your-key.pem" # can use password keyword in Connection instead
srv = pysftp.Connection(host="your-host", username="user-name", private_key=private_key)
srv.chdir('/var/web/public_files/media/uploads') # change directory on remote server
srv.put(file_path) # To download a file, replace put with get
srv.close() # Close connection
pysftp is an easy to use sftp module that utilizes paramiko and pycrypto. It provides a simple interface to sftp.. Other things that you can do with pysftp which are quite useful:
data = srv.listdir() # Get the directory and file listing in a list
srv.get(file_path) # Download a file from remote server
srv.execute('pwd') # Execute a command on the server
More commands and about PySFTP here.
Example: Inside myWindow() on line 3 is the code you need to set the window in the center of the screen.

window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.getContentPane().setBackground(Color.BLACK);
window.setLayout(null); // disable the default layout to use custom one.
window.setVisible(true); // to show the window on the screen.

Goto the SDK manager in your IDE and install the latest "Intel HAXM" and start the emulator.
If it is throwing the error as
Starting emulator for AVD 'X86'
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX is not installed on this machine (/dev/HAX is missing).
It means that some hardware graphical features are to be assigned.So to overcome this problem just go to the path where you have your Adroid SDK
installed.
C:\Android\SDK\extras\intel\Hardware_Accelerated_Execution_Manager
There you can find the file intelhaxm-android.exe
.
On Mac OSXthere is a IntelHAXM_X.X.X.dmg
file, mount it and you'll find an mpkg-file.
Install the file and restart all the applications using android emulator such as(android studio,cmd etc..,).
Now try to open the emulator it will work fine

One other thing that affected me: If you have multiple test devices, make sure you are making changes to the layout used by the device. In my case, I spent a while making changes to xmls in the "layout" directory until I discovered that my larger phone (which I switched to halfway through testing) was using xmls in the "layout-sw360dp" directory. Grrr!
I would think that your first question is simply a matter of scope. The ServletContext is a much more broad scoped object (the whole servlet context) than a ServletRequest, which is simply a single request. You might look to the Servlet specification itself for more detailed information.
As to how, I am sorry but I will have to leave that for others to answer at this time.
for i in range (1,10):
string="string"+str(i)
To get string0, string1 ..... string10
, you could do like
>>> ["string"+str(i) for i in range(11)]
['string0', 'string1', 'string2', 'string3', 'string4', 'string5', 'string6', 'string7', 'string8', 'string9', 'string10']
For Python 3
Remove the rb
argument and use either r
or don't pass argument (default read mode
).
with open( <path-to-file>, 'r' ) as theFile:
reader = csv.DictReader(theFile)
for line in reader:
# line is { 'workers': 'w0', 'constant': 7.334, 'age': -1.406, ... }
# e.g. print( line[ 'workers' ] ) yields 'w0'
print(line)
For Python 2
import csv
with open( <path-to-file>, "rb" ) as theFile:
reader = csv.DictReader( theFile )
for line in reader:
# line is { 'workers': 'w0', 'constant': 7.334, 'age': -1.406, ... }
# e.g. print( line[ 'workers' ] ) yields 'w0'
Python has a powerful built-in CSV handler. In fact, most things are already built in to the standard library.
This exception can raise when you handle Deep linking
or URL for a browser, if there is no default installed. In case of Deep linking there may be no application installed that can process a link in format myapp://mylink
.
You can use the tangerine solution for API up to 29:
private fun openUrl(url: String) {
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
val activityInfo = intent.resolveActivityInfo(packageManager, intent.flags)
if (activityInfo?.exported == true) {
startActivity(intent)
} else {
Toast.makeText(
this,
"No application that can handle this link found",
Toast.LENGTH_SHORT
).show()
}
}
For API >= 30 see intent.resolveActivity returns null in API 30.
I usually create a view and use the DESC
command:
CREATE VIEW tmp_view AS
SELECT
a.name
, a.surname
, b.ordernum
FROM customer a
JOIN orders b
ON a.id = b.id
Then, the DESC
command will show the type of each field.
DESC tmp_view
Do you want to make the label (except for the text) transparent? Windows Forms (I assume WinForms - is this true) doesn't really support transparency. The easiest way, sometimes, is Label's Backcolor to Transparent.
label1.BackColor = System.Drawing.Color.Transparent;
You will run into problems though, as WinForms really doesn't properly support transparency. Otherwise, see here:
http://www.doogal.co.uk/transparent.php
http://www.codeproject.com/KB/dotnet/transparent_controls_net.aspx
http://www.daniweb.com/code/snippet216425.html
Setting the parent of a usercontrol prevents it from being transparent
Good luck!
Webpack
is a bundler. Like Browserfy
it looks in the codebase for module requests (require
or import
) and resolves them recursively. What is more, you can configure Webpack
to resolve not just JavaScript-like modules, but CSS, images, HTML, literally everything. What especially makes me excited about Webpack
, you can combine both compiled and dynamically loaded modules in the same app. Thus one get a real performance boost, especially over HTTP/1.x. How exactly you you do it I described with examples here http://dsheiko.com/weblog/state-of-javascript-modules-2017/
As an alternative for bundler one can think of Rollup.js
(https://rollupjs.org/), which optimizes the code during compilation, but stripping all the found unused chunks.
For AMD
, instead of RequireJS
one can go with native ES2016 module system
, but loaded with System.js
(https://github.com/systemjs/systemjs)
Besides, I would point that npm
is often used as an automating tool like grunt
or gulp
. Check out https://docs.npmjs.com/misc/scripts. I personally go now with npm scripts only avoiding other automation tools, though in past I was very much into grunt
. With other tools you have to rely on countless plugins for packages, that often are not good written and not being actively maintained. npm
knows its packages, so you call to any of locally installed packages by name like:
{

Actually you as a rule do not need any plugin if the package supports CLI.
str(object)
will do the trick.
If you want to alter the way object is stringified, define __str__(self)
method for object's class. Such method has to return str or unicode object.
The answer from niaher stating that to use the fluent API you need a custom extension may have been correct at the time of writing. You can now (EF core 2.1) use the fluent API as follows:
modelBuilder.Entity<ClassName>()
.HasIndex(a => new { a.Column1, a.Column2}).IsUnique();
Holstebroe's comment would be your best answer:
string s = string.Format("{0}", myObj);
If myObj
is null, Format places an Empty String value there.
It also satisfies your one line requirement and is easy to read.
Even I got the same compilation error when I was cross compiling i686-cm-linux-gcc.
The below compilation option solved my problem
$ i686-cm-linux-gcc a.c --sysroot=/opt/toolchain/i686-cm-linux-gcc
Note: The sysroot should point to compiler directory where usr/include available
In my case the toolchain is installed at /opt/toolchain/i686-cm-linux-gcc directory and usr/include is also available in the same directory
You can use select2 plugin for creating such a filter. With this lot's of coding work can be avoided. You can grab the plugin from https://select2.github.io/
This plugin is much simple to apply and even advanced work can be easily done with it. :)
In my opinion early return is fine if you are just returning void (or some useless return code you're never gonna check) and it might improve readability because you avoid nesting and at the same time you make explicit that your function is done.
If you are actually returning a returnValue - nesting is usually a better way to go cause you return your returnValue just in one place (at the end - duh), and it might make your code more maintainable in a whole lot of cases.
If the 'Cool Options' are hidden from the view before the field is focused then you would want to create this in JQuery instead of having it in the DOM so anyone using a screen reader wouldn't see unnecessary information. Why should they have to listen to it when we don't have to see it?
So you can setup variables like so:
var $coolOptions= $("<div id='options'></div>").text("Some cool options");
and then append (or prepend) on focus
$("input[name='input_name']").focus(function() {
$(this).append($coolOptions);
});
and then remove when the focus ends
$("input[name='input_name']").focusout(function() {
$('#options').remove();
});
This will do. Pretty trustworthy. : )
""+number;
Just to clarify, this works and acceptable to use unless you are looking for micro optimization.
Did you check your Project Properties -> Project Facets
panel? (From that post)
A WTP project is composed of multiple units of functionality (known as facets).
The Java facet version needs to always match the java compiler compliance level.
The best way to change java level is to use the Project Facets properties panel as that will update both places at the same time.
The "
Project->Preferences->Project Facets
" stores its configuration in this file, "org.eclipse.wst.common.project.facet.core.xml
", under the ".settings
" directory.The content might look like this
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<runtime name="WebSphere Application Server v6.1"/>
<fixed facet="jst.java"/>
<fixed facet="jst.web"/>
<installed facet="jst.java" version="5.0"/>
<installed facet="jst.web" version="2.4"/>
<installed facet="jsf.ibm" version="7.0"/>
<installed facet="jsf.base" version="7.0"/>
<installed facet="web.jstl" version="1.1"/>
</faceted-project>
Check also your Java compliance level:
Quick update to mid 2015:
You can use the Postgres Foreign Data interface, to store the files in more suitable database. For example put the files in a GridFS which is part of MongoDB. Then use https://github.com/EnterpriseDB/mongo_fdw to access it in Postgres.
That has the advantages, that you can access/read/write/backup it in Postrgres and MongoDB, depending on what gives you more flexiblity.
There are also foreign data wrappers for file systems: https://wiki.postgresql.org/wiki/Foreign_data_wrappers#File_Wrappers
As an example you can use this one: https://multicorn.readthedocs.org/en/latest/foreign-data-wrappers/fsfdw.html (see here for brief usage example)
That gives you the advantage of the consistency (all linked files are definitely there) and all the other ACIDs, while there are still on the actual file system, which means you can use any file system you want and the webserver can serve them directly (OS caching applies too).
Pehaps...ok, very likely, I'm missing something, but why not just create an object type, say NSNumber, as a container to your non-object type variable, such as CGFloat?
CGFloat myFloat = 2.0;
NSNumber *myNumber = [NSNumber numberWithFloat:myFloat];
[self performSelector:@selector(MyCalculatorMethod:) withObject:myNumber afterDelay:5.0];
Use the method setAnimation(null) to stop an animation, it exposed as public method in
View.java, it is the base class for all widgets, which are used to create interactive UI components (buttons, text fields, etc.).
/**
* Sets the next animation to play for this view.
* If you want the animation to play immediately, use
* {@link #startAnimation(android.view.animation.Animation)} instead.
* This method provides allows fine-grained
* control over the start time and invalidation, but you
* must make sure that 1) the animation has a start time set, and
* 2) the view's parent (which controls animations on its children)
* will be invalidated when the animation is supposed to
* start.
*
* @param animation The next animation, or null.

On ubuntu most perl modules are already packaged, so installing is much faster than most other systems which have to compile.
To install Foo::Bar
at a commmand prompt for example usually you just do:
sudo apt-get install libfoo-bar-perl
Sadly not all modules follow that naming convention.
From previous project experience, this is a good way:
In the constants.js:
// constants.js
'use strict';
let constants = {
key1: "value1",
key2: "value2",
key3: {
subkey1: "subvalue1",
subkey2: "subvalue2"
}
};
module.exports =
Object.freeze(constants); // freeze prevents changes by users
In main.js (or app.js, etc.), use it as below:
// main.js
let constants = require('./constants');
console.log(constants.key1);
console.dir(constants.key3);
My solution on using ObjectId
// usermodel.js
const mongoose = require('mongoose')
const Schema = mongoose.Schema
const ObjectId = Schema.Types.ObjectId
let UserSchema = new Schema({
username: {
type: String
},
events: [{
type: ObjectId,
ref: 'Event' // Reference to some EventSchema
}]
})
UserSchema.set('autoIndex', true)
module.exports = mongoose.model('User', UserSchema)
Using mongoose's populate method
// controller.js
const mongoose = require('mongoose')
const User = require('./usermodel.js')
let query = User.findOne({ name: "Person" })
query.exec((err, user) => {
if (err) {
console.log(err)
}
user.events = events
// user.events is now an array of events
})
I was having this issue on OS X and it seemed to be caused by a version mismatch between my globally installed webpack
and my locally installed webpack-dev-server
. Updating both to the latest version got rid of the issue.
Memory Engine is not the solution you're looking for. You lose everything that you went to a database for in the first place (i.e. ACID).
Here are some better alternatives:
A LEFT [OUTER] JOIN can be faster than an equivalent subquery because the server might be able to optimize it better—a fact that is not specific to MySQL Server alone.
The last point is key. I used to love joins, but then had to run joins on a few tables with 100M+ rows. No good. Better off insert the data you're joining against into that target table (if it's not too much) and query against indexed columns and you'll get your query in a few ms.
I hope those help.
Solution when dropping a list of column names containing regex. I prefer this approach because I'm frequently editing the drop list. Uses a negative filter regex for the drop list.
drop_column_names = ['A','B.+','C.*']
drop_columns_regex = '^(?!(?:'+'|'.join(drop_column_names)+')$)'
print('Dropping columns:',', '.join([c for c in df.columns if re.search(drop_columns_regex,c)]))
df = df.filter(regex=drop_columns_regex,axis=1)
You can use the -B
option.
-B, --block-size=SIZE use SIZE-byte blocks
All together,
df -BG
I apologize for reviving this thread, but there was a strategy not discussed here which may be applicable.
Using reflection it is possible to do something akin to forward declaration. For instance lets say you have a section of code that looks like this:
# We want to call a function called 'foo', but it hasn't been defined yet.
function_name = 'foo'
# Calling at this point would produce an error
# Here is the definition
def foo():
bar()
# Note that at this point the function is defined
# Time for some reflection...
globals()[function_name]()
So in this way we have determined what function we want to call before it is actually defined, effectively a forward declaration. In python the statement globals()[function_name]()
is the same as foo()
if function_name = 'foo'
for the reasons discussed above, since python must lookup each function before calling it. If one were to use the timeit
module to see how these two statements compare, they have the exact same computational cost.
Of course the example here is very useless, but if one were to have a complex structure which needed to execute a function, but must be declared before (or structurally it makes little sense to have it afterwards), one can just store a string and try to call the function later.
If I want tranfer only the response variable y instead of a linear model with x specified, eg I wanna transfer/normalize a list of data, I can take 1 for x, then the object becomes a linear model:
library(MASS)
y = rf(500,30,30)
hist(y,breaks = 12)
result = boxcox(y~1, lambda = seq(-5,5,0.5))
mylambda = result$x[which.max(result$y)]
mylambda
y2 = (y^mylambda-1)/mylambda
hist(y2)
An option for your application would be to write a replacement Home Screen using the android.intent.category.HOME Intent. I believe this type of Intent you can see the home button.

This will work for any field you pass to it. (IMPORTANT: It will only order alphabetically so if you pass a date it will order it as alphabet not as date)

The simplest way is to just redirect the output, like so:
Compare-Object $(Get-Content c:\user\documents\List1.txt) $(Get-Content c:\user\documents\List2.txt) > c:\user\documents\diff_output.txt
>
will cause the output file to be overwritten if it already exists.
>>
will append new text to the end of the output file if it already exists.
If you use Python3x then string
is not the same type as for Python 2.x, you must cast it to bytes (encode it).
plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wb") as outfile:
outfile.write(bytes(plaintext, 'UTF-8'))
Also do not use variable names like string
or file
while those are names of module or function.
EDIT @Tom
Yes, non-ASCII text is also compressed/decompressed. I use Polish letters with UTF-8 encoding:
plaintext = 'Polish text: acelnószzACELNÓSZZ'
filename = 'foo.gz'
with gzip.open(filename, 'wb') as outfile:
outfile.write(bytes(plaintext, 'UTF-8'))
with gzip.open(filename, 'r') as infile:
outfile_content = infile.read().decode('UTF-8')
print(outfile_content)
The problem is that date is a reserved sqlite3 keyword. I had a similar problem with time, also a reserved keyword, which worked fine in PostgreSQL, but not in sqlite3. The solution is renaming the column.
See this: Sqlite3 activerecord :order => "time DESC" doesn't sort
If you know what class the field is on you can access it using reflection. This example (it's in Groovy but the method calls are identical) gets a Field object for the class Foo and gets its value for the object b
. It shows that you don't have to care about the exact concrete class of the object, what matters is that you know the class the field is on and that that class is either the concrete class or a superclass of the object.
groovy:000> class Foo { def stuff = "asdf"}
===> true
groovy:000> class Bar extends Foo {}
===> true
groovy:000> b = new Bar()
===> Bar@1f2be27
groovy:000> f = Foo.class.getDeclaredField('stuff')
===> private java.lang.Object Foo.stuff
groovy:000> f.getClass()
===> class java.lang.reflect.Field
groovy:000> f.setAccessible(true)
===> null
groovy:000> f.get(b)
===> asdf

A cookie is just another HTTP header. You can always set it while making a HTTP call with the apache library or with HTTPUrlConnection. Either way you should be able to read and set HTTP cookies in this fashion.

If you open the root project folder in Android Studio, you wont see the options suggested in other answers in this page.
Instead of the root folder I opened the packages/native/android
folder. Then only I could see the options to build signed APK.
I know its a bit late now, but you could do something such as this:
function AddToArray ($post_information) {
//Create the return array
$return = array();
//Iterate through the array passed
foreach ($post_information as $key => $value) {
//Append the key and value to the array, e.g.
//$_POST['keys'] = "values" would be in the array as "keys"=>"values"
$return[$key] = $value;
}
//Return the created array
return $return;
}
The test with:
if (isset($_POST['submit'])) {
var_dump(AddToArray($_POST));
}
This for me produced:
array (size=1)
0 =>
array (size=5)
'stake' => string '0' (length=1)
'odds' => string '' (length=0)
'ew' => string 'false' (length=5)
'ew_deduction' => string '' (length=0)
'submit' => string 'Open' (length=4)
If you have a lot of variables in your Rdata
file and don't want them to clutter your global environment, create a new environment and load all of the data to this new environment.
load(file.path("C:/Users/isfar.RData"), isfar_env <- new.env() )
# Access individual variables in the RData file using '$' operator
isfar_env$var_name
# List all of the variable names in RData:
ls(isfar_env)
You can use TEXT
like this as part of a concatenation
=TEXT(A1,"dd-mmm-yy") & " other string"
You could wrap the hidden div in another div that will toggle the visibility with onMouseOver and onMouseOut event handlers in JavaScript:
<style type="text/css">
#div1, #div2, #div3 {
visibility: hidden;
}
</style>
<script>
function show(id) {
document.getElementById(id).style.visibility = "visible";
}
function hide(id) {
document.getElementById(id).style.visibility = "hidden";
}
</script>
<div onMouseOver="show('div1')" onMouseOut="hide('div1')">
<div id="div1">Div 1 Content</div>
</div>
<div onMouseOver="show('div2')" onMouseOut="hide('div2')">
<div id="div2">Div 2 Content</div>
</div>
<div onMouseOver="show('div3')" onMouseOut="hide('div3')">
<div id="div3">Div 3 Content</div>
</div>

This situation occurred to me when I uninstalled a method and tried to reinstall it. My very same interpreter, which worked before, suddenly stopped working. And this error occurred.
I tried restarting my PC, reinstalling Pycharm, invalidating caches, nothing worked.

When you install it, there's an option to fix the python.exe interpreter. Click that. My IDE went back to normal working conditions.
They JKS file is just a container for certificates and key pairs. In a client-side authentication scenario, the various parts of the keys will be located here:
The separation of truststore and keystore is not mandatory but recommended. They can be the same physical file.
To set the filesystem locations of the two stores, use the following system properties:
-Djavax.net.ssl.keyStore=clientsidestore.jks
and on the server:
-Djavax.net.ssl.trustStore=serversidestore.jks
To export the client's certificate (public key) to a file, so you can copy it to the server, use
keytool -export -alias MYKEY -file publicclientkey.cer -store clientsidestore.jks
To import the client's public key into the server's keystore, use (as the the poster mentioned, this has already been done by the server admins)
keytool -import -file publicclientkey.cer -store serversidestore.jks
I had the same problem once. Calling invalidate after changing visibility almost always works, but in some cases it doesn't. I had to cheat and set the background to a transparent image and set the text to "".
If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.

This is the same question as Failed to connect to mailserver at "localhost" port 25

removeChild
should be invoked on the parent, i.e.:

Child.prototype.constructor = Child; // constructor alignment
var a = new Child();
console.log(a.name); // "default name" trying to reach property of inherited class

Take a clone of a remote repository and run git branch -a
(to show all the branches git knows about). It will probably look something like this:
* master
remotes/origin/HEAD -> origin/master
remotes/origin/master
Here, master
is a branch in the local repository. remotes/origin/master
is a branch named master
on the remote named origin
. You can refer to this as either origin/master
, as in:
git diff origin/master..master
You can also refer to it as remotes/origin/master
:
git diff remotes/origin/master..master
These are just two different ways of referring to the same thing (incidentally, both of these commands mean "show me the changes between the remote master
branch and my master
branch).
remotes/origin/HEAD
is the default branch
for the remote named origin
. This lets you simply say origin
instead of origin/master
.

# Mouse position and button clicking.
pos = pygame.mouse.get_pos()
pressed1, pressed2, pressed3 = pygame.mouse.get_pressed()
# Check if the rect collided with the mouse pos

Because a string variable is a reference, not an instance.
Initializing it to Empty by default would have been possible but it would have introduced a lot of inconsistencies all over the board.
On Windows and Linux, it's AltShiftA, as RichieHindle pointed out. On OSX it's OptionCommandA (??A). It's also worth noting that the two modes can have different font preferences, so if you've changed the default text font, it can be jarring to toggle block selection modes and see the font change.
Finally, the "search commands" (Ctrl3 or Command3) pop-up will find it for you if you type block. This is useful if you use the feature just frequently enough to forget the hotkey.
I had to rescale the bitmap a bit to not exceed the 1mb limit of the transaction binder. You can adapt the 400 the your screen or make it dinamic it's just meant to be an example. It works fine and the quality is nice. Its also a lot faster then saving the image and loading it after but you have the size limitation.
public void loadNextActivity(){
Intent confirmBMP = new Intent(this,ConfirmBMPActivity.class);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap bmp = returnScaledBMP();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, stream);
confirmBMP.putExtra("Bitmap",bmp);
startActivity(confirmBMP);
finish();
}
public Bitmap returnScaledBMP(){
Bitmap bmp=null;
bmp = tempBitmap;
bmp = createScaledBitmapKeepingAspectRatio(bmp,400);
return bmp;
}
After you recover the bmp in your nextActivity with the following code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_confirmBMP);
Intent intent = getIntent();
Bitmap bitmap = (Bitmap) intent.getParcelableExtra("Bitmap");
}
I hope my answer was somehow helpfull. Greetings

I actually came across this same problem recently and ended up with a slightly different approach (I wasn't able to use background images). It does require a tiny bit of jQuery though to determine the orientation of the images (I' sure you could use plain JS instead though).
I wrote a blog post about it if you are interested in more explaination but the code is pretty simple:
HTML:
<ul class="cropped-images">
<li><img src="http://fredparke.com/sites/default/files/cat-portrait.jpg" /></li>
<li><img src="http://fredparke.com/sites/default/files/cat-landscape.jpg" /></li>
</ul>
CSS:
li {
width: 150px; // Or whatever you want.
height: 150px; // Or whatever you want.
overflow: hidden;
margin: 10px;
display: inline-block;
vertical-align: top;
}
li img {
max-width: 100%;
height: auto;
width: auto;
}
li img.landscape {
max-width: none;
max-height: 100%;
}
jQuery:
$( document ).ready(function() {
$('.cropped-images img').each(function() {
if ($(this).width() > $(this).height()) {
$(this).addClass('landscape');
}
});
});
The primary flag seems to only work for vagrant ssh
for me.
In the past I have used the following method to hack around the issue.
# stage box intended for configuration closely matching production if ARGV[1] == 'stage' config.vm.define "stage" do |stage| box_setup stage, \ "10.9.8.31", "deploy/playbook_full_stack.yml", "deploy/hosts/vagrant_stage.yml" end end
In my memory, excel (versions >= 2007) limits the power 2 of 20: 1.048.576 lines.
Csv is over to this boundary, like ordinary text file. So you will be care of the transfer between two formats.
The cause for me receiving this error was trying the new pre-release VSCode JS debugger.
If you opted in, change via User settings:
"debug.javascript.usePreview": true|false
Everything in my normal configuration and integrated terminal was correct and finding executables. I wasted a lot of time trying other things!
Here is the Power Shell script which I used by taking the reference of:

It's !=
without type coercion. See the MDN documentation for comparison operators.
Also see this StackOverflow answer, which includes a quote from "JavaScript: The Good Parts" about the problems with ==
and !=
. (null == undefined
, false == "0"
, etc.)
Short answer: always use ===
and !==
unless you have a compelling reason to do otherwise. (Tools like JSLint, JSHint, ESLint, etc. will give you this same advice.)
Or alternatively, you could use this:
WHERE CHARINDEX(N'Apples', someColumn) = 0
Not sure which one performs better - you gotta test it! :-)
Marc
UPDATE: the performance seems to be pretty much on a par with the other solution (WHERE someColumn NOT LIKE '%Apples%') - so it's really just a question of your personal preference.
Very rarely.
I'd say only at the top level of a thread in order to ATTEMPT to issue a message with the reason for a thread dying.
If you are in a framework that does this sort of thing for you, leave it to the framework.
For modern, mobile browsers:
document.addEventListener('contextmenu', callback);
https://developer.mozilla.org/en-US/docs/Web/Events/contextmenu
Your test:
if (numberSet.length < 2) {
return 0;
}
should be done before you allocate an array of that length in the below statement:
int[] differenceArray = new int[numberSet.length-1];
else you are already creating an array of size -1
, when the numberSet.length = 0
. That is quite odd. So, move your if statement
as the first statement in your method.
None of the above solutions worked for me. What finally worked was:
Instead of
import android.support.v4.content.FileProvider;
Use this
import androidx.core.content.FileProvider;
This path is updated as of AndroidX (the repackaged Android Support Library).
Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.
So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.
Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.
If you're developing in Flutter, there's a new experimental option as of 5/1/2018 that allows you to format code on save.
when use "ConfigurationUserLevel.None" your code is right run when you click in nameyourapp.exe in debug folder. .
but when your do developing app on visual stdio not right run!! because "vshost.exe" is run.
following parameter solve this problem : "Application.ExecutablePath"
try this : (Tested in VS 2012 Express For Desktop)
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
config.AppSettings.Settings["PortName"].Value = "com3";
config.Save(ConfigurationSaveMode.Minimal);
my english not good , i am sorry.

I think this String.Equals is what you need.
Dim aaa = "12/31"
Dim a = String.Equals(aaa, "06/30")
a will return false.
Cardinality of a set is the namber of the elements in set for we have a set a > a,b,c < so ths set contain 3 elements 3 is the cardinality of that set
Passing data from PHP is easy, you can generate JavaScript with it. The other way is a bit harder - you have to invoke the PHP script by a Javascript request.
An example (using traditional event registration model for simplicity):
<!-- headers etc. omitted -->
<script>
function callPHP(params) {
var httpc = new XMLHttpRequest(); // simplified for clarity
var url = "get_data.php";
httpc.open("POST", url, true); // sending as POST
httpc.onreadystatechange = function() { //Call a function when the state changes.
if(httpc.readyState == 4 && httpc.status == 200) { // complete and no errors
alert(httpc.responseText); // some processing here, or whatever you want to do with the response
}
};
httpc.send(params);
}
</script>
<a href="#" onclick="callPHP('lorem=ipsum&foo=bar')">call PHP script</a>
<!-- rest of document omitted -->
Whatever get_data.php
produces, that will appear in httpc.responseText. Error handling, event registration and cross-browser XMLHttpRequest compatibility are left as simple exercises to the reader ;)

Firstly, easiest way to one hot encode: use Sklearn.
http://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.OneHotEncoder.html
Secondly, I don't think using pandas to one hot encode is that simple (unconfirmed though)
Creating dummy variables in pandas for python
Lastly, is it necessary for you to one hot encode? One hot encoding exponentially increases the number of features, drastically increasing the run time of any classifier or anything else you are going to run. Especially when each categorical feature has many levels. Instead you can do dummy coding.
Using dummy encoding usually works well, for much less run time and complexity. A wise prof once told me, 'Less is More'.
Here's the code for my custom encoding function if you want.
from sklearn.preprocessing import LabelEncoder
#Auto encodes any dataframe column of type category or object.
def dummyEncode(df):
columnsToEncode = list(df.select_dtypes(include=['category','object']))
le = LabelEncoder()
for feature in columnsToEncode:
try:
df[feature] = le.fit_transform(df[feature])
except:
print('Error encoding '+feature)
return df
EDIT: Comparison to be clearer:
One-hot encoding: convert n levels to n-1 columns.
Index Animal Index cat mouse
1 dog 1 0 0
2 cat --> 2 1 0
3 mouse 3 0 1
You can see how this will explode your memory if you have many different types (or levels) in your categorical feature. Keep in mind, this is just ONE column.
Dummy Coding:
Index Animal Index Animal
1 dog 1 0
2 cat --> 2 1
3 mouse 3 2
Convert to numerical representations instead. Greatly saves feature space, at the cost of a bit of accuracy.
To prove jkp's point that 'anything on one line will probably be helishly complex to understand', I created a one-liner. Please do not mod me down because I understand this is not a solution that you should actually use. It is just for demonstrational purposes.
The idea is to add the values in a one by one, as long as the total times you have added that value does is smaller than the total number of times this value is in a minus the number of times it is in b:
[ value for counter,value in enumerate(a) if a.count(value) >= b.count(value) + a[counter:].count(value) ]
The horror! But perhaps someone can improve on it? Is it even bug free?
Edit: Seeing Devin Jeanpierre comment about using a dictionary datastructure, I came up with this oneliner:
sum([ [value]*count for value,count in {value:a.count(value)-b.count(value) for value in set(a)}.items() ], [])
Better, but still unreadable.
You can pivot your DataFrame after creating:
>>> df = pd.DataFrame(data)
>>> df.pivot(index=0, columns=1, values=2)
# avg DataFrame
1 c1 c2
0
r1 avg11 avg12
r2 avg21 avg22
>>> df.pivot(index=0, columns=1, values=3)
# stdev DataFrame
1 c1 c2
0
r1 stdev11 stdev12
r2 stdev21 stdev22
To find in the parent of the iFrame use:
$('#parentPrice', window.parent.document).html();
The second parameter for the $() wrapper is the context in which to search. This defaults to document.
I resolved this issue by correcting an error with my Global.asax file arrangement. I had copied across the files from another project and failed to embed the Global.asax.cs within the Global.asax file (both files previously existed at the same level).
It's already a string? Remove the getText() call.
int myNum = 0;
try {
myNum = Integer.parseInt(myString);
} catch(NumberFormatException nfe) {
// Handle parse error.
}
Use os.walk to iterate recursively over directory content:
import os
root_dir = '.'
for directory, subdirectories, files in os.walk(root_dir):
for file in files:
print os.path.join(directory, file)
No real difference between os.system and subprocess.call here - unless you have to deal with strangely named files (filenames including spaces, quotation marks and so on). If this is the case, subprocess.call is definitely better, because you don't need to do any shell-quoting on file names. os.system is better when you need to accept any valid shell command, e.g. received from user in the configuration file.
