If someone is facing issue using texttocolumns function in UFT. Please try using below function.
myxl.Workbooks.Open myexcel.xls
myxl.Application.Visible = false `enter code here`
set mysheet = myxl.ActiveWorkbook.Worksheets(1)
Set objRange = myxl.Range("A1").EntireColumn
Set objRange2 = mysheet.Range("A1")
objRange.TextToColumns objRange2,1,1, , , , true
Here we are using coma(,) as delimiter.
You can't extend Enum
as it's a static class. You can only extend instances of a type. With this in mind, you're going to have to create a static method yourself to do this; the following should work when combined with your existing method GetDescription
:
public static class EnumHelper
{
public static T GetEnumFromString<T>(string value)
{
if (Enum.IsDefined(typeof(T), value))
{
return (T)Enum.Parse(typeof(T), value, true);
}
else
{
string[] enumNames = Enum.GetNames(typeof(T));
foreach (string enumName in enumNames)
{
object e = Enum.Parse(typeof(T), enumName);
if (value == GetDescription((Enum)e))
{
return (T)e;
}
}
}
throw new ArgumentException("The value '" + value
+ "' does not match a valid enum name or description.");
}
}
And the usage of it would be something like this:
Animal giantPanda = EnumHelper.GetEnumFromString<Animal>("Giant Panda");
The Unconstrained Melody library is no longer maintained; Support was dropped in favour of Enums.NET.
In Enums.NET you'd use:
string description = ((MyEnum)value).AsString(EnumFormat.Description);
I implemented this in a generic, type-safe way in Unconstrained Melody - you'd use:
string description = Enums.GetDescription((MyEnum)value);
This:
I realise the core answer was just the cast from an int
to MyEnum
, but if you're doing a lot of enum work it's worth thinking about using Unconstrained Melody :)
My variant
public struct Colors
{
private String current;
private static string red = "#ff0000";
private static string green = "#00ff00";
private static string blue = "#0000ff";
private static IList<String> possibleColors;
public static Colors Red { get { return (Colors) red; } }
public static Colors Green { get { return (Colors) green; } }
public static Colors Blue { get { return (Colors) blue; } }
static Colors()
{
possibleColors = new List<string>() {red, green, blue};
}
public static explicit operator String(Colors value)
{
return value.current;
}
public static explicit operator Colors(String value)
{
if (!possibleColors.Contains(value))
{
throw new InvalidCastException();
}
Colors color = new Colors();
color.current = value;
return color;
}
public static bool operator ==(Colors left, Colors right)
{
return left.current == right.current;
}
public static bool operator !=(Colors left, Colors right)
{
return left.current != right.current;
}
public bool Equals(Colors other)
{
return Equals(other.current, current);
}
public override bool Equals(object obj)
{
if (ReferenceEquals(null, obj)) return false;
if (obj.GetType() != typeof(Colors)) return false;
return Equals((Colors)obj);
}
public override int GetHashCode()
{
return (current != null ? current.GetHashCode() : 0);
}
public override string ToString()
{
return current;
}
}
Code looks a bit ugly, but usages of this struct are pretty presentative.
Colors color1 = Colors.Red;
Console.WriteLine(color1); // #ff0000
Colors color2 = (Colors) "#00ff00";
Console.WriteLine(color2); // #00ff00
// Colors color3 = "#0000ff"; // Compilation error
// String color4 = Colors.Red; // Compilation error
Colors color5 = (Colors)"#ff0000";
Console.WriteLine(color1 == color5); // True
Colors color6 = (Colors)"#00ff00";
Console.WriteLine(color1 == color6); // False
Also, I think, if a lot of such enums required, code generation (e.g. T4) might be used.
In addition to previous post you can have
<h:form rendered="#{!bean.boolvalue}" />
<h:form rendered="#{bean.textvalue == 'value'}" />

To get the actual access_token
, you can also do pro grammatically via the following PHP code:
require 'facebook.php';
$facebook = new Facebook(array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
));
// Get User ID
$user = $facebook->getUser();
if ($user) {
try {
$user_profile = $facebook->api('/me');
$access_token = $facebook->getAccessToken();
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
In my case, I put
apply plugin: 'com.google.gms.google-services'
at the bottom of build.gradle
file and set multiDexEnabled true
in defaultConfig. Then just run and it works.
Try as follows the return must be d, not d.data
ajax: {
"url": "xx/xxx/xxx",
"type": "GET",
"error": function (e) {
},
"dataSrc": function (d) {
return d
}
},
There is a alter way. Open the excel file in Microsoft office Excel, and save it as "Excel 97-2003 Workbook". Then, use the new saved excel file in your file connection.
I am joining the choir recommending that you skip the now long outdated classes Date
, Calendar
, SimpleDateFormat
and friends. In particular I would warn against using the deprecated methods and constructors of the Date
class, like the Date(String)
constructor you used. They were deprecated because they don’t work reliably across time zones, so don’t use them. And yes, most of the constructors and methods of that class are deprecated.
While at the time you asked the question, Joda-Time was (from all I know) a clearly better alternative, time has moved on again. Today Joda-Time is a largely finished project, and its developers recommend you use java.time
, the modern Java date and time API, instead. I will show you how.
ZonedDateTime localTime = ZonedDateTime.now(ZoneId.systemDefault());
// Convert Local Time to UTC
OffsetDateTime gmtTime
= localTime.toOffsetDateTime().withOffsetSameInstant(ZoneOffset.UTC);
System.out.println("Local:" + localTime.toString()
+ " --> UTC time:" + gmtTime.toString());
// Reverse Convert UTC Time to Local time
localTime = gmtTime.atZoneSameInstant(ZoneId.systemDefault());
System.out.println("Local Time " + localTime.toString());
For starters, note that not only is the code only half as long as yours, it is also clearer to read.
On my computer the code prints:
Local:2017-09-02T07:25:46.211+02:00[Europe/Berlin] --> UTC time:2017-09-02T05:25:46.211Z
Local Time 2017-09-02T07:25:46.211+02:00[Europe/Berlin]
I left out the milliseconds from the epoch. You can always get them from System.currentTimeMillis();
as in your question, and they are independent of time zone, so I didn’t find them intersting here.
I hesitatingly kept your variable name localTime
. I think it’s a good name. The modern API has a class called LocalTime
, so using that name, only not capitalized, for an object that hasn’t got type LocalTime
might confuse some (a LocalTime
doesn’t hold time zone information, which we need to keep here to be able to make the right conversion; it also only holds the time-of-day, not the date).
Your conversion from local time to UTC was incorrect and impossible
The outdated Date
class doesn’t hold any time zone information (you may say that internally it always uses UTC), so there is no such thing as converting a Date
from one time zone to another. When I just ran your code on my computer, the first line it printed, was:
Local:Sat Sep 02 07:25:45 CEST 2017,1504329945967 --> UTC time:Sat Sep 02 05:25:45 CEST 2017-1504322745000
07:25:45 CEST
is correct, of course. The correct UTC time would have been 05:25:45 UTC
, but it says CEST
again, which is incorrect.
Now you will never need the Date
class again, :-) but if you were ever going to, the must-read would be All about java.util.Date on Jon Skeet’s coding blog.
Question: Can I use the modern API with my Java version?
If using at least Java 6, you can.

Your mock is raising the exception just fine, but the error.resp.status
value is missing. Rather than use return_value
, just tell Mock
that status
is an attribute:
barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
Additional keyword arguments to Mock()
are set as attributes on the resulting object.
I put your foo
and bar
definitions in a my_tests
module, added in the HttpError
class so I could use it too, and your test then can be ran to success:
>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
... barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
... result = my_test.foo()
...
404 -
>>> result is None
True
You can even see the print '404 - %s' % error.message
line run, but I think you wanted to use error.content
there instead; that's the attribute HttpError()
sets from the second argument, at any rate.
In Linux I navigated to the directory containing the .sql file before starting mysql. The system cursor is now in the same location as the file and you won't need a path. Use source myData.sql where my date is replaced with the name of your file.
cd whatever directory
mysql - p
connect targetDB
source myData.sql
Done
When you return something from a then()
callback, it's a bit magic. If you return a value, the next then()
is called with that value. However, if you return something promise-like, the next then()
waits on it, and is only called when that promise settles (succeeds/fails).

I was trying to save a JSON object from a XHR request into a HTML5 data-* attribute. I tried many of above solutions with no success.
What I finally end up doing was replacing the single quote '
with it code '
using a regex after the stringify() method call the following way:
var productToString = JSON.stringify(productObject);
var quoteReplaced = productToString.replace(/'/g, "'");
var anchor = '<a data-product=\'' + quoteReplaced + '\' href=\'#\'>' + productObject.name + '</a>';
// Here you can use the "anchor" variable to update your DOM element.
Try adding log_errors = Off and check the error_reporting setting whether it's set high enough.
Interesting but try this with floated li elements inside the ul: Example here
The problem now: the ul needs a fixed width to actually sit in the center. However we want to be it relative to the container width (or dynamic), margin: 0 auto on the ul does not work.
A better way is to let go of UL/Li list and use a different approach example here
In UTF-8:
1 byte: 0 - 7F (ASCII)
2 bytes: 80 - 7FF (all European plus some Middle Eastern)
3 bytes: 800 - FFFF (multilingual plane incl. the top 1792 and private-use)
4 bytes: 10000 - 10FFFF
In UTF-16:
2 bytes: 0 - D7FF (multilingual plane except the top 1792 and private-use )
4 bytes: D800 - 10FFFF
In UTF-32:
4 bytes: 0 - 10FFFF
10FFFF is the last unicode codepoint by definition, and it's defined that way because it's UTF-16's technical limit.
It is also the largest codepoint UTF-8 can encode in 4 byte, but the idea behind UTF-8's encoding also works for 5 and 6 byte encodings to cover codepoints until 7FFFFFFF, ie. half of what UTF-32 can.
None of the examples above create 8-bit (8bpp) bitmap images. Some software, such as image processing, only supports 8bpp. Unfortunately the MS .NET libraries do not have a solution. The PixelFormat.Format8bppIndexed format looks promising but after a lot of attempts I couldn't get it working.
To create a true 8-bit bitmap file you need to create the proper headers. Ultimately I found the Grayscale library solution for creating 8-bit bitmap (BMP) files. The code is very simple:
Image image = Image.FromFile("c:/path/to/image.jpg");
GrayBMP_File.CreateGrayBitmapFile(image, "c:/path/to/8bpp/image.bmp");
The code for this project is far from pretty but it works, with one little simple-to-fix problem. The author hard-coded the image resolution to 10x10. Image processing programs do not like this. The fix is open GrayBMP_File.cs (yeah, funky file naming, I know) and replace lines 50 and 51 with the code below. The example sets the resolution to 200x200 but you should change it to the proper number.
int resX = 200;
int resY = 200;
// horizontal resolution
Copy_to_Index(DIB_header, BitConverter.GetBytes(resX * 100), 24);
// vertical resolution
Copy_to_Index(DIB_header, BitConverter.GetBytes(resY * 100), 28);
Thanks @John Leehey and @PeterH:
desiredSp = getResources().getDimension(R.dimen.desired_sp);
density = getResources().getDisplayMetrics().density;
textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, desiredSp / density);
The thing is if you define R.dimen.desired_sp to 25 in your dimen.xml

This is a warning for usual. You can either disable it by
#pragma warning(disable:4996)
or simply use fopen_s like Microsoft has intended.
But be sure to use the pragma before other headers.
To add to @Hima's answer, if you want to modify a current x or y limit you could use the following.
import numpy as np # you probably alredy do this so no extra overhead
fig, axes = plt.subplot()
axes.plot(data[:,0], data[:,1])
xlim = axes.get_xlim()
# example of how to zoomout by a factor of 0.1
factor = 0.1
new_xlim = (xlim[0] + xlim[1])/2 + np.array((-0.5, 0.5)) * (xlim[1] - xlim[0]) * (1 + factor)
axes.set_xlim(new_xlim)
I find this particularly useful when I want to zoom out or zoom in just a little from the default plot settings.
All tags must have enclosing tags. In my case, the hr and input elements weren't closed properly.
Parent Error was: JSX element 'div' has no corresponding closing tag, due to code below:
<hr class="my-4">
<input
type="password"
id="inputPassword"
class="form-control"
placeholder="Password"
required
>
Fix:
<hr class="my-4"/>
<input
type="password"
id="inputPassword"
class="form-control"
placeholder="Password"
required
/>
The parent elements will show errors due to child element errors. Therefore, start investigating from most inner elements up to the parent ones.
I wanted to add a very simple workflow from someone who has been frustrated with git in the past. There are several ways to use git, probably the most common for unity are GitHub Desktop, Git Bash and GitHub Unity
https://assetstore.unity.com/packages/tools/version-control/github-for-unity-118069.
Essentially they all do the same thing but its user choice. You can have git for large file setup which allows 1GB free large file storage with additional storage available in data packs for $4/mo for 50GB, and this will allow you to push files >100mb to remote repositories (it stores the actual files on a server and in your repo a pointer)
If you don't want to setup lfs for whatever reason you can scan your projects for files > 128 mb in windows by typing size:large in the directory where you have your project. This can be handy to search for large files, although there may be some files between 100mb and 128mb that get missed.
The general format of git bash is
git add . (adds files to be commited)
git commit -m 'message' (commits the files with a message, they are still on your pc and not in the remote repo, basically they have been 'versioned' as a new commit)
git push (push files to the repository)
The disadvantage of git bash for unity projects is that if there is a file > 100mb, you won't get an error until you push. You then have to undo your commit by resetting your head to the previous commit. Kind of a hassle, especially if you are new with git bash.
The advantage of GitHub Desktop, is BEFORE you commit files with 100mb it will give you a popup error message. You can then shrink those files or add them to a .gitignore file.
To use a .gitignore file, create a file called .gitignore in your local repository root directory. Simply add the files one line at a time you would like to omit. SharedAssets and other non-Asset folder files can usually be omitted and will automatically repopulate in the editor (packages can be re-imported etc). You can also use wildcards to exclude file types.
If other people are using your GitHub repo and you want to clone or pull you have those options available to you as well on GitHub desktop or Git bash.
I did not mention much about Unity GitHub package where you can use GitHub in the editor because personally I did not find the interface very useful, and I don't think overall its going to help anyone get familiar with git, but this is just my preference.
$result2 is resource link not a string to echo
it or to replace some of its parts with str_replace()
.
another important point is that Random.nextInt(n) is repeatable since you can create two Random object with the same seed. This is not possible with Math.random().
$(document).ready(function () {
$("#divId").toggleClass('cssclassname'); // toggle class
});
**OR**
$(document).ready(function() {
$("#objectId").click(function() { // click or other event to change the div class
$("#divId").toggleClass("cssclassname"); // toggle class
)};
)};
That depends on what you want to do, but as you said, getting an entity reference using find()
and then just updating that entity is the easiest way to do that.
I'd not bother about performance differences of the various methods unless you have strong indications that this really matters.
Here's another way to process command line args, using R CMD BATCH
. My approach, which builds on an earlier answer here, lets you specify arguments at the command line and, in your R script, give some or all of them default values.
Here's an R file, which I name test.R:
defaults <- list(a=1, b=c(1,1,1)) ## default values of any arguments we might pass
## parse each command arg, loading it into global environment
for (arg in commandArgs(TRUE))
eval(parse(text=arg))
## if any variable named in defaults doesn't exist, then create it
## with value from defaults
for (nm in names(defaults))
assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]))[[1]])
print(a)
print(b)
At the command line, if I type
R CMD BATCH --no-save --no-restore '--args a=2 b=c(2,5,6)' test.R
then within R we'll have a
= 2
and b
= c(2,5,6)
. But I could, say, omit b
, and add in another argument c
:
R CMD BATCH --no-save --no-restore '--args a=2 c="hello"' test.R
Then in R we'll have a
= 2
, b
= c(1,1,1)
(the default), and c
= "hello"
.
Finally, for convenience we can wrap the R code in a function, as long as we're careful about the environment:
## defaults should be either NULL or a named list
parseCommandArgs <- function(defaults=NULL, envir=globalenv()) {
for (arg in commandArgs(TRUE))
eval(parse(text=arg), envir=envir)
for (nm in names(defaults))
assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]), envir=envir)[[1]], pos=envir)
}
## example usage:
parseCommandArgs(list(a=1, b=c(1,1,1)))
This should work:
$("#table-filters>ul>li.active").removeClass("active");
//Find all `li`s with class `active`, children of `ul`s, children of `table-filters`
I don't know if this is new functionality, but this will plot on separate figures:
df.plot(y='korisnika')
df.plot(y='osiguranika')
while this will plot on the same figure: (just like the code in the op)
df.plot(y=['korisnika','osiguranika'])
I found this question because I was using the former method and wanted them to plot on the same figure, so your question was actually my answer.
Java doesn't have associative arrays like PHP does.
There are various solutions for what you are doing, such as using a Map, but it depends on how you want to look up the information. You can easily write a class that holds all your information and store instances of them in an ArrayList
.
public class Foo{
public String name, fname;
public Foo(String name, String fname){
this.name = name;
this.fname = fname;
}
}
And then...
List<Foo> foos = new ArrayList<Foo>();
foos.add(new Foo("demo","fdemo"));
foos.add(new Foo("test","fname"));
So you can access them like...
foos.get(0).name;
=> "demo"
I just want to correct a point here. ELF file is produced by the Linker, not the compiler.
The Compiler mission ends after producing the object files (*.o) out of the source code files. Linker links all .o files together and produces the ELF.
This answer is similar to others with requests
and BeautifulSoup
, but using list comprehension.
Because find_all()
is the most popular method in the Beautiful Soup search API, you can use soup("a")
as a shortcut of soup.findAll("a")
and using list comprehension:
import requests
from bs4 import BeautifulSoup
URL = "http://www.yourwebsite.com"
page = requests.get(URL)
soup = BeautifulSoup(page.content, features='lxml')
# Find links
all_links = [link.get("href") for link in soup("a")]
# Only external links
ext_links = [link.get("href") for link in soup("a") if "http" in link.get("href")]
https://www.crummy.com/software/BeautifulSoup/bs4/doc/#calling-a-tag-is-like-calling-find-all
#include <math.h>
double round(double x);
float roundf(float x);
Don't forget to link with -lm. See also ceil(), floor() and trunc().
According to your scenario, IllegalArgumentException
is the best pick, because null
is not a valid value for your property.
If you want to use an array, you have to keep a counter which contains the number of cars in the garage. Better use an ArrayList
instead of array:
List<Car> garage = new ArrayList<Car>();
garage.add(redCar);
adb shell
am start -n com.package.name/com.package.name.ActivityName
Or you can use this directly:
adb shell am start -n com.package.name/com.package.name.ActivityName
You can also specify actions to be filter by your intent-filters:
am start -a com.example.ACTION_NAME -n com.package.name/com.package.name.ActivityName
You cannot use a variable in a create table statement. The best thing I can suggest is to write the entire query as a string and exec that.
Try something like this:
declare @query varchar(max);
set @query = 'create database TEST...';
exec (@query);
This explains the whole thing:
The HTTP Content-Security-Policy (CSP) upgrade-insecure-requests directive instructs user agents to treat all of a site's insecure URLs (those served over HTTP) as though they have been replaced with secure URLs (those served over HTTPS). This directive is intended for web sites with large numbers of insecure legacy URLs that need to be rewritten.
The upgrade-insecure-requests directive is evaluated before block-all-mixed-content and if it is set, the latter is effectively a no-op. It is recommended to set one directive or the other, but not both.
The upgrade-insecure-requests directive will not ensure that users visiting your site via links on third-party sites will be upgraded to HTTPS for the top-level navigation and thus does not replace the Strict-Transport-Security (HSTS) header, which should still be set with an appropriate max-age to ensure that users are not subject to SSL stripping attacks.
OR
.section:hover > div {
background-color: #0CF;
}
NOTE Parent element state can only affect a child's element state so you can use:
.image:hover + .layer {
background-color: #0CF;
}
.image:hover {
background-color: #0CF;
}
but you can not use
.layer:hover + .image {
background-color: #0CF;
}
If you are returning a complex json object you need to modify you success function of your auto-complete as follows.
$.ajax({
url: "/Employees/SearchEmployees",
dataType: "json",
data: {
searchText: request.term
},
success: function (data) {
response($.map(data.employees, function (item) {
return {
label: item.name,
value: item.id
};
}));
}
});
The following was all done in cygwin on a Windows XP box.
This will get your IP address. Note that there are backquotes around the hostname command, not single quotes.
ping -n 1 `hostname` | grep "Reply from " | cut -f 3 -d " " | cut -f 1 -d ":"
This will get your subnet.
ping -n 1 `hostname` | grep "Reply from " | cut -f 3 -d " " | cut -f "1 2 3" -d "."
The following will list all hosts on your local network (put it into a script called "netmap"). I had taken the subnet line above and put it into an executable called "getsubnet", which I then called from the following script.
MINADDR=0
MAXADDR=255
SUBNET=`getsubnet`
hostcnt=0
echo Pinging all addresses in ${SUBNET}.${MINADDR}-${MAXADDR}
for i in `seq $MINADDR $MAXADDR`; do
addr=${SUBNET}.$i
ping -n 1 -w 0 $addr > /dev/null
if [ $? -ne 1 ]
then
echo $addr UP
hostcnt=$((hostcnt+1))
fi
done
echo Found $hostcnt hosts on subnet ${SUBNET}.${MINADDR}-${MAXADDR}

A unique constraint can't be over 8000 bytes per row and will only use the first 900 bytes even then so the safest maximum size for your keys would be:
create table [misc_info]
(
[id] INTEGER PRIMARY KEY IDENTITY NOT NULL,
[key] nvarchar(450) UNIQUE NOT NULL,
[value] nvarchar(max) NOT NULL
)
i.e. the key can't be over 450 characters. If you can switch to varchar
instead of nvarchar
(e.g. if you don't need to store characters from more than one codepage) then that could increase to 900 characters.

Because nil cannot be stored in Foundation data structures NSNull
is sometimes to represent a nil
. Because NSNull
is a singleton object you can check to see if NSNull
is the value stored in dictionary by using direct pointer comparison:
if ((NSNull *)[user objectForKey:@"myKey"] == [NSNull null]) { }
If splitting very large files, the solution I found is an adaptation from this, with PowerShell "embedded" in a batch file. This works fast, as opposed to many other things I tried (I wouldn't know about other options posted here).
The way to use mysplit.bat
below is
mysplit.bat <mysize> 'myfile'
Note: The script was intended to use the first argument as the split size. It is currently hardcoded at 100Mb. It should not be difficult to fix this.
Note 2: The filname should be enclosed in single quotes. Other alternatives for quoting apparently do not work.
Note 3: It splits the file at given number of bytes, not at given number of lines. For me this was good enough. Some lines of code could be probably added to complete each chunk read, up to the next CR/LF. This will split in full lines (not with a constant number of them), with no sacrifice in processing time.

There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.
The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.
Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.
Best way would be first of all find all files in directory then use AWK NR (Number of Records Variable)
below is the command :
find <directory path> -type f | awk 'END{print NR}'
example : - find /tmp/ -type f | awk 'END{print NR}'
Python 2 will automatically set the type based on the size of the value. A guide of max values can be found below.
The Max value of the default Int in Python 2 is 65535, anything above that will be a long
For example:
>> print type(65535)
<type 'int'>
>>> print type(65536*65536)
<type 'long'>
In Python 3 the long datatype has been removed and all integer values are handled by the Int class. The default size of Int will depend on your CPU architecture.
For example:
The min/max values of each type can be found below:
If the size of your Int exceeds the limits mentioned above, python will automatically change it's type and allocate more memory to handle this increase in min/max values. Where in Python 2, it would convert into 'long', it now just converts into the next size of Int.
Example: If you are using a 32 bit operating system, your max value of an Int will be 2147483647 by default. If a value of 2147483648 or more is assigned, the type will be changed to Int64.
There are different ways to check the size of the int and it's memory allocation.
Note: In Python 3, using the built-in type() method will always return <class 'int'>
no matter what size Int you are using.
$("#closeLink").click(closeIt);
Let's say you want to call your function passing some args to it i.e., closeIt(1, false)
. Then, you should build an anonymous function and call closeIt
from it.
$("#closeLink").click(function() {
closeIt(1, false);
});
Try following query to get dates between the range:
SELECT *
FROM Product_sales
WHERE From_date >= '2013-01-03' AND
To_date <= '2013-01-09'
To make it more interesting and to hopefully enable less hair pulling for someone else. Using python, built dictionary for a device which we can use curl to configure.
Problem: {"timezone":"+5"} //throws an error " 5"
Solution: {"timezone":"%2B"+"5"} //Works
So, in a nutshell:
var = {"timezone":"%2B"+"5"}
json = JSONEncoder().encode(var)
subprocess.call(["curl",ipaddress,"-XPUT","-d","data="+json])
Thanks to this post!
The command is lowercase: touch filename
.
Keep in mind that touch
will only create a new file if it does not exist! Here's some docs for good measure: http://unixhelp.ed.ac.uk/CGI/man-cgi?touch
If you always want an empty file, one way to do so would be to use:
echo "" > filename
If move_uploaded_file() is not working for you and you are not getting any errors (like in my case), make sure that the size of the file/image you are uploading is not greater than upload_max_filesize value in php.ini.
My upload_max_filesize value was 2MB on my localhost and I kept trying to upload a 4MB image for countless times while trying to figure out what the issue with move_uploaded_file() is.
There are two methods that come to mind:
You could use Contains like so:
if (ddlCustomerNumber.Items.Contains(new
ListItem(GetCustomerNumberCookie().ToString())))
{
// ... code here
}
or modifying your current strategy:
if (ddlCustomerNumber.Items.FindByText(
GetCustomerNumberCookie().ToString()) != null)
{
// ... code here
}
EDIT: There's also a DropDownList.Items.FindByValue
that works the same way as FindByText, except it searches based on values instead.
Here is what works for me on Swift 3
let _ = (dict[key].map { $0 as? String } ?? "")

fixes major and minor numbers. It is used when you're ready to accept bug-fixes in your dependency, but don't want any potentially incompatible changes.
^
fixes the major number only. It is used when you're closely watching your dependencies and are ready to quickly change your code if minor release will be incompatible.
In addition to that, ^
is not supported by old npm versions, and should be used with caution.
So, ^
is a good default, but it's not perfect. I suggest to carefully pick and configure the semver operator that is most useful to you.
Linux: Remove redundant paths from $PATH variable
Linux From Scratch has this function in /etc/profile
# Functions to help us manage paths. Second argument is the name of the
# path variable to be modified (default: PATH)
pathremove () {
local IFS=':'
local NEWPATH
local DIR
local PATHVARIABLE=${2:-PATH}
for DIR in ${!PATHVARIABLE} ; do
if [ "$DIR" != "$1" ] ; then
NEWPATH=${NEWPATH:+$NEWPATH:}$DIR
fi
done
export $PATHVARIABLE="$NEWPATH"
}
This is intended to be used with these functions for adding to the path, so that you don't do it redundantly:
pathprepend () {
pathremove $1 $2
local PATHVARIABLE=${2:-PATH}
export $PATHVARIABLE="$1${!PATHVARIABLE:+:${!PATHVARIABLE}}"
}
pathappend () {
pathremove $1 $2
local PATHVARIABLE=${2:-PATH}
export $PATHVARIABLE="${!PATHVARIABLE:+${!PATHVARIABLE}:}$1"
}
Simple usage is to just give pathremove
the directory path to remove - but keep in mind that it has to match exactly:
$ pathremove /home/username/anaconda3/bin
This will remove each instance of that directory from your path.
If you want the directory in your path, but without the redundancies, you could just use one of the other functions, e.g. - for your specific case:
$ pathprepend /usr/local/sbin
$ pathappend /usr/local/bin
$ pathappend /usr/sbin
$ pathappend /usr/bin
$ pathappend /sbin
$ pathappend /bin
$ pathappend /usr/games
But, unless readability is the concern, at this point you're better off just doing:
$ export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
I would presume the above to work in sh
, dash
, and bash
at least. I would be surprised to learn it doesn't work in csh
, fish', or
ksh`. I doubt it would work in Windows command shell or Powershell.
If you have Python, the following sort of command should do what is directly asked (that is, remove redundant paths):
$ PATH=$( python -c "
import os
path = os.environ['PATH'].split(':')
print(':'.join(sorted(set(path), key=path.index)))
" )
A one-liner (to sidestep multiline issues):
$ PATH=$( python -c "import os; path = os.environ['PATH'].split(':'); print(':'.join(sorted(set(path), key=path.index)))" )
The above removes later redundant paths. To remove earlier redundant paths, use a reversed list's index and reverse it again:
$ PATH=$( python -c "
import os
path = os.environ['PATH'].split(':')[::-1]
print(':'.join(sorted(set(path), key=path.index, reverse=True)))
" )
<script>
$(document).ready(function(){
$('#connectBtn').click(function(e){
e.preventDefault();
})
});
</script>
This will prevent the default action.
Its really a bad experience. if the above answer didn't work for you try this.
Click on the Settings icon and then click on the Restore defaults and reload button.
Press 'F8' until its became normal.
Happy coding!!
Only IE and WebKit support zoom, and yes, in theory it does exactly what you're saying.
Try it out on an image to see it's full effect :)
The form post values are stored under the name of the form in the request. For example, if you've overridden the getName()
method of ContactType() to return "contact", you would do this:
$postData = $request->request->get('contact');
$name_value = $postData['name'];
If you're still having trouble, try doing a var_dump()
on $request->request->all()
to see all the post values.
To build on JJC's helpful answer that builds on Louis's helpful answer...
With PhantomJS 2.1.1-windows this line works:
driver.execute_script("return navigator.userAgent")
If it doesn't work, you can still get the user agent via the log (to build on Mma's answer):
from selenium import webdriver
import json
from fake_useragent import UserAgent
dcap = dict(DesiredCapabilities.PHANTOMJS)
dcap["phantomjs.page.settings.userAgent"] = (UserAgent().random)
driver = webdriver.PhantomJS(executable_path=r"your_path", desired_capabilities=dcap)
har = json.loads(driver.get_log('har')[0]['message']) # get the log
print('user agent: ', har['log']['entries'][0]['request']['headers'][1]['value'])
Here you get JSONObject so change this line:
JSONArray jsonArray = new JSONArray(readlocationFeed);
with following:
JSONObject jsnobject = new JSONObject(readlocationFeed);
and after
JSONArray jsonArray = jsnobject.getJSONArray("locations");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject explrObject = jsonArray.getJSONObject(i);
}
I did sudo chmod 777 -R .
to be able to change the permissions. Without sudo
, it wouldn't work, giving me the same error as running other commands.
Now you can do svn update
or whatever, without having to scrap your entire directory and recreating it. This is especially helpful, since your IDE or text editor may already have certain tabs open, or have syncing problems. You don't need to scrap and replace your working directory with this method.
Enter the first in the series and select that cell, then series fill (HOME > Editing - Fill, Series..., Columns):
It is very fast and the results are values not formulae.

Sometimes it's asking the question that makes the answer jump out. The methods and extra arguments are listed on the ggplot2 wiki stat_smooth page.
Which is alluded to on the geom_smooth()
page with:
"See stat_smooth for examples of using built in model fitting if you need some more flexible, this example shows you how to plot the fits from any model of your choosing".
It's not the first time I've seen arguments in examples for ggplot graphs that aren't specifically in the function. It does make it tough to work out the scope of each function, or maybe I am yet to stumble upon a magic explicit list that says what will and will not work within each function.
Even better!
long tStart = System.nanoTime();
long tEnd = System.nanoTime();
long tRes = tEnd - tStart; // time in nanoseconds
Read the documentation about nanoTime()!
Simply updated Xcode. Solved my problem
This look like a duplicate of JSTL conditional check.
The error is having the &&
outside the expression. Instead use
<c:if test="${ISAJAX == 0 && ISDATE == 0}">
Given the following sample
myData <- data.frame(A=rep(1:2, 3), B=rep(1:3, 2), Pulse=20:25)
then
myData$A <-as.factor(myData$A)
myData$B <-as.factor(myData$B)
or you could select your columns altogether and wrap it up nicely:
# select columns
cols <- c("A", "B")
myData[,cols] <- data.frame(apply(myData[cols], 2, as.factor))
levels(myData$A) <- c("long", "short")
levels(myData$B) <- c("1kg", "2kg", "3kg")
To obtain

3 long 3kg 22
4 short 1kg 23
5 long 2kg 24

Try INC_DIR=../ ../StdCUtil
.
Then, set CCFLAGS=-c -Wall $(addprefix -I,$(INC_DIR))
EDIT: Also, modify your #include
to be #include <StdCUtil/split.h>
so that the compiler knows to use -I rather than local path of the .cpp using the #include
.

What I did when I wanted to draw a dotted line is to define a drawable dash_line.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line" >
<stroke
android:dashGap="3dp"
android:dashWidth="2dp"
android:width="1dp"
android:color="@color/black" />
</shape>
And then in the layout just define a view with background as dash_line. Note to include android:layerType="software", otherwise it won't work.
<View
android:layout_width="match_parent"
android:layout_height="5dp"
android:background="@drawable/dash_line"
android:layerType="software" />
You can do this by using the --prefix
flag and the --global
* flag.
pje@friendbear:~/foo $ npm install bower -g --prefix ./vendor/node_modules
[email protected] /Users/pje/foo/vendor/node_modules/bower
*Even though this is a "global" installation, installed bins won't be accessible through the command line unless ~/foo/vendor/node_modules
exists in PATH
.
Every configurable attribute of npm
can be set in any of six different places. In order of priority:
--prefix ./vendor/node_modules
NPM_CONFIG_PREFIX=./vendor/node_modules
$HOME/.npmrc
or userconfig
param$PREFIX/etc/npmrc
or userconfig
parampath/to/npm/itself/npmrc
By default, locally-installed packages go into ./node_modules
. global ones go into the prefix
config variable (/usr/local
by default).
You can run npm config list
to see your current config and npm config edit
to change it.
In general, npm
's documentation is really helpful. The folders section is a good structural overview of npm and the config section answers this question.
I tried to start my binary, compiled with Qt 5.7
, on Ubuntu 16.04 LTS where Qt 5.5
is preinstalled. It didn't work.
At first, I inspected the binary itself with ldd
as was suggested here, and "satisfied" all "not found" dependencies. Then this notorious This application failed to start because it could not find or load the Qt platform plugin "xcb"
error was thrown.
Firstly you should create platforms
directory where your binary is, because it is the place where Qt looks for XCB library. Copy libqxcb.so
there. I wonder why authors of other answers didn't mention this.
Then you may want to run your binary with QT_DEBUG_PLUGINS=1
environment variable set to check which dependencies of libqxcb.so
are not "satisfied". (You may also use ldd
for this as suggested in the accepted answer).
The command output may look like this:
me@xerus:/media/sf_Qt/Package$ LD_LIBRARY_PATH=. QT_DEBUG_PLUGINS=1 ./Binary

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
Available platform plugins are: xcb.
Reinstalling the application may fix this problem.
Aborted (core dumped)
Note the failing libQt5DBus.so.5
library. Copy it to your libraries path, in my case it was the same directory where my binary is (hence LD_LIBRARY_PATH=.
). Repeat this process until all dependencies are satisfied.
P.S. thanks to the author of this answer for QT_DEBUG_PLUGINS=1
.
Finally I made it work thanks to the steps outlined in the Eclipse forum:
eval `ssh-agent`
ssh-add C:/User/you/ssh/id_rsa
ssh [email protected]
Here is what you just did: You ran the ssh-agent which is needed by ssh-add. Then you used ssh-add to make note of the location of your key. Then you tried to ssh to GitHub. The response to this last command should be that you have successfully authenticated at GitHub but that you don't have shell access. This is just an authentication test. If the authentication was not successful, you'll have to sort that out. Try the verbose version:
ssh -v [email protected]
Assuming this worked....
Select ssh as the protocol but then go back to the URI box and add "git+" at the beginning so it looks like this:
git+ssh://[email protected]/UserName/ProjectName.git
In the Repository Path box, remove the leading slash
Instead of using SSH [email protected] I did it with SSH [email protected].
Now I can push and import without any problem.
use auto and min or max width like this:
td {
max-width:50px;
width:auto;
min-width:10px;
}
You can use this function. It will replace the commas with ' ' and then it will parseFlaot the value and after that it will again adjust the commas in value.
function convertToFloat(val) {
if (val != '') {
if (val.indexOf(',') !== -1)
val.replace(',', '');
val = parseFloat(val);
while (/(\d+)(\d{3})/.test(val.toString())) {
val = val.toString().replace(/(\d+)(\d{3})/, '$1' + ',' + '$2');
}
}
return val;
}
Not sure if this will satisfy all, but I found a simple workaround that fixed the problem for me. Move all your referenced cells/formulas to a different sheet so that you aren't referencing any cells in the sheet that has the table to be sorted. If you do this, you can sort away!
Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:
http://msdn.microsoft.com/en-us/library/ms681381.aspx
You can also use command line utility net
to find information about a Win32 error code. The syntax would be:

For me, it was having my code folder in Dropbox on windows 10. During the build process Dropbox would flip out over having more than 500,000 files. I moved my folder out and now it builds fine!
I might be a bit late for the party but I follow below steps to make it fully configurable using IntelliJ's way of in-IDE app test. I believe the best way to go with is to Combine below with @BelusC's answer.
1. run the application using IDE's tomcat run config.
2. ps -ef | grep -i tomcat //this will give you a good idea about what the ide doing actually.
3. Copy the -Dcatalina.base parameter value from the command. this is your application specific catalina base. In this folder you can play with catalina.properties, application root path etc.. basically everything you have been doing is doable here too.
In my case, I was using RxSwift for performing search.
I had extensively kept using a shared instance of a particular class inside the onNext method, which probably made it inaccessible (Mutex).
Make sure that such instances are handled carefully only when absolutely necessary.
In my case, I made use of a couple of variables beforehand to safely (and sequentially) store the return values of the shared instance's methods, and reused them inside onNext block.
Just put .htaccess into the folder you want to restrict
## no access to this folder
# Apache 2.4
<IfModule mod_authz_core.c>
Require all denied
</IfModule>
# Apache 2.2
<IfModule !mod_authz_core.c>
Order Allow,Deny
Deny from all

I assume by "key" and "value" you mean:
<select>
<option value="KEY">VALUE</option>
</select>
If that's the case, this will get you the "VALUE":
$(this).find('option:selected').text();
And you can get the "KEY" like this:
$(this).find('option:selected').val();
You have to write your own method in this case. Use a loop and get each character using charAt(i)
and set it to your Character[]
array using arrayname[i] = string.charAt[i]
.
My machine configurations :
Operating System : Windows 10 Version 1703 (x64)
I faced this error while debugging my C# .Net project in Visual Studio 2017 Community edition. I was calling a native method by performing p/invoke on a C++ assembly loaded at run-time. I encountered the very same error reported by OP.
I realized that Visual Studio was launched with a user account which was not an administrator on the machine. Then I relaunched Visual Studio under a different user account which was an administrator on the machine. That's all. My problem got resolved and I didn't face the issue again.
One thing to note is that the method which was being invoked on C++ assembly was supposed to write few things in registry. I didn't go debugging the C++ code to do some RCA but I see a possibility that the whole thing was failing as administrative privileges are required to write registry in Windows 10 operating system. So earlier when Visual Studio was running under a user account which didn't have administrative privileges on the machine, then the native calls were failing.
try this (ExtensionMethods):
public static string ToJson(this DataTable dt)
{
List<Dictionary<string, object>> lst = new List<Dictionary<string, object>>();
Dictionary<string, object> item;
foreach (DataRow row in dt.Rows)
{
item = new Dictionary<string, object>();
foreach (DataColumn col in dt.Columns)
{
item.Add(col.ColumnName, (Convert.IsDBNull(row[col]) ? null : row[col]));
}
lst.Add(item);
}
return Newtonsoft.Json.JsonConvert.SerializeObject(lst);
}
and use:
DataTable dt = new DataTable();
.
.
.
var json = dt.ToJson();
'Caret' is the word you are looking for. I do believe though, that it is part of the browsers design, and not within the grasp of css.
However, here is an interesting write up on simulating a caret change using Javascript and CSS http://www.dynamicdrive.com/forums/showthread.php?t=17450 It seems a bit hacky to me, but probably the only way to accomplish the task. The main point of the article is:
We will have a plain textarea somewhere in the screen out of the view of the viewer and when the user clicks on our "fake terminal" we will focus into the textarea and when the user starts typing we will simply append the data typed into the textarea to our "terminal" and that's that.
HERE is a demo in action
There is a new css property caret-color
which applies to the caret of an input
or contenteditable
area. The support is growing but not 100%, and this only affects color, not width or other types of appearance.
input{_x000D_
caret-color: rgb(0, 200, 0);_x000D_
}
_x000D_
<input type="text"/>
_x000D_
if (listView1.Items.Count > 0)
{
listView1.Items[0].Selected = true;
listView1.Select();
}
list items do not appear selected unless the control has the focus (or you set the HideSelection
property to false)
Not directly. But you can use extensions such as LESS to help you achieve the same.
I've tried sean662's 3rd solution and worked with now() function stored in an INSERT sql an then it's value in the date_create() function. After that the variable is then passed through the date_format() function and you can have the date order that you like.
Here is obscure solution: define macro function:
#define Z(x) \
(x==0 ? 'A' : \
(x==1 ? 'B' : \
(x==2 ? 'C' : '\0')))
char x[] = { Z(0), Z(1), Z(2) };
clearfix
should contain the floating elements but in your html you have added clearfix
only after floating right that is your pull-right
so you should do like this:
<div class="clearfix">
<div id="sidebar">
<ul>
<li>A</li>
<li>A</li>
<li>C</li>
<li>D</li>
<li>E</li>
<li>F</li>
<li>...</li>
<li>Z</li>
</ul>
</div>
<div id="main">
<div>
<div class="pull-right">
<a>RIGHT</a>
</div>
</div>
<div>MOVED BELOW Z</div>
</div>
Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden;
as you have done in your main.
You just subindex it with [:5]
indicating that you want (up to) the first 5 elements.
>>> [1,2,3,4,5,6,7,8][:5]
[1, 2, 3, 4, 5]
>>> [1,2,3][:5]
[1, 2, 3]
>>> x = [6,7,8,9,10,11,12]
>>> x[:5]
[6, 7, 8, 9, 10]
Also, putting the colon on the right of the number means count from the nth element onwards -- don't forget that lists are 0-based!
>>> x[5:]
[11, 12]
I know this is an old question, but HTML5 offers a couple new options.
The first is to separate the form from the toolbar in the markup, add another form for the delete action, and associate the buttons in the toolbar with their respective forms using the form
attribute.
<form id="saveForm" action="/post/dispatch/save" method="post">
<input type="text" name="foo" /> <!-- several of those here -->
</form>
<form id="deleteForm" action="/post/dispatch/delete" method="post">
<input type="hidden" value="some_id" />
</form>
<div id="toolbar">
<input type="submit" name="save" value="Save" form="saveForm" />
<input type="submit" name="delete" value="Delete" form="deleteForm" />
<a href="/home/index">Cancel</a>
</div>
This option is quite flexible, but the original post also mentioned that it may be necessary to perform different actions with a single form. HTML5 comes to the rescue, again. You can use the formaction
attribute on submit buttons, so different buttons in the same form can submit to different URLs. This example just adds a clone method to the toolbar outside the form, but it would work the same nested in the form.
<div id="toolbar">
<input type="submit" name="clone" value="Clone" form="saveForm"
formaction="/post/dispatch/clone" />
</div>

The advantage of these new features is that they do all this declaratively without JavaScript. The disadvantage is that they are not supported on older browsers, so you'd have to do some polyfilling for older browsers.
As Leo points out, the code you added to your question would not suggest a strong reference cycle (a.k.a., retain cycle). One operation-related issue that could cause a strong reference cycle would be if the operation is not getting released. While your code snippet suggests that you have not defined your operation to be concurrent, but if you have, it wouldn't be released if you never posted isFinished
, or if you had circular dependencies, or something like that. And if the operation isn't released, the view controller wouldn't be released either. I would suggest adding a breakpoint or NSLog
in your operation's dealloc
method and confirm that's getting called.
You said:
I understand the notion of retain cycles, but I am not quite sure what happens in blocks, so that confuses me a little bit
The retain cycle (strong reference cycle) issues that occur with blocks are just like the retain cycle issues you're familiar with. A block will maintain strong references to any objects that appear within the block, and it will not release those strong references until the block itself is released. Thus, if block references self
, or even just references an instance variable of self
, that will maintain strong reference to self, that is not resolved until the block is released (or in this case, until the NSOperation
subclass is released.
For more information, see the Avoid Strong Reference Cycles when Capturing self section of the Programming with Objective-C: Working with Blocks document.
If your view controller is still not getting released, you simply have to identify where the unresolved strong reference resides (assuming you confirmed the NSOperation
is getting deallocated). A common example is the use of a repeating NSTimer
. Or some custom delegate
or other object that is erroneously maintaining a strong
reference. You can often use Instruments to track down where objects are getting their strong references, e.g.:
Or in Xcode 5:
It's Ctrl + Alt + L for Windows. For a complete list of keyboard shortcuts please take a look at the user manual: https://developer.android.com/studio/intro/keyboard-shortcuts.html
Swift 5+:

boolean isEquals(List<String> firstList, List<String> secondList){
ArrayList<String> commons = new ArrayList<>();
for (String s2 : secondList) {
for (String s1 : firstList) {
if(s2.contains(s1)){
commons.add(s2);
}
}
}
firstList.removeAll(commons);
secondList.removeAll(commons);
return !(firstList.size() > 0 || secondList.size() > 0) ;
}
You need to specify the branch. By default it listens to anything. See the blog post Hudson: Git and Maven plugins.
foo = {}
foo[#foo+1]="bar"
foo[#foo+1]="baz"
This works because the #
operator computes the length of the list. The empty list has length 0, etc.
If you're using Lua 5.3+, then you can do almost exactly what you wanted:
foo = {}
setmetatable(foo, { __shl = function (t,v) t[#t+1]=v end })
_= foo << "bar"
_= foo << "baz"
Expressions are not statements in Lua and they need to be used somehow.

Just call Math.abs. For example:
int x = Math.abs(-5);
Which will set x
to 5
.
Note that if you pass Integer.MIN_VALUE
, the same value (still negative) will be returned, as the range of int
does not allow the positive equivalent to be represented.
I agree with @adietisheim and the rest of people that suggest HttpClient.
I spent time trying to make a simple call to rest service with HttpURLConnection and it hadn't convinced me and after that I tried with HttpClient and it was really more easy, understandable and nice.
An example of code to make a put http call is as follows:
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPut putRequest = new HttpPut(URI);
StringEntity input = new StringEntity(XML);
input.setContentType(CONTENT_TYPE);
putRequest.setEntity(input);
HttpResponse response = httpClient.execute(putRequest);
In the notation
u'Capit\xe1n\n'
the "\xe1" represents just one byte. "\x" tells you that "e1" is in hexadecimal. When you write
Capit\xc3\xa1n
into your file you have "\xc3" in it. Those are 4 bytes and in your code you read them all. You can see this when you display them:
>>> open('f2').read()
'Capit\\xc3\\xa1n\n'
You can see that the backslash is escaped by a backslash. So you have four bytes in your string: "\", "x", "c" and "3".
Edit:
As others pointed out in their answers you should just enter the characters in the editor and your editor should then handle the conversion to UTF-8 and save it.
If you actually have a string in this format you can use the string_escape
codec to decode it into a normal string:
In [15]: print 'Capit\\xc3\\xa1n\n'.decode('string_escape')
Capitán
The result is a string that is encoded in UTF-8 where the accented character is represented by the two bytes that were written \\xc3\\xa1
in the original string. If you want to have a unicode string you have to decode again with UTF-8.
To your edit: you don't have UTF-8 in your file. To actually see how it would look like:
s = u'Capit\xe1n\n'
sutf8 = s.encode('UTF-8')
open('utf-8.out', 'w').write(sutf8)
Compare the content of the file utf-8.out
to the content of the file you saved with your editor.
This has nothing to do with Spring MVC testing.
When you don't declare a ViewResolver
, Spring registers a default InternalResourceViewResolver
which creates instances of JstlView
for rendering the View
.
The JstlView
class extends InternalResourceView
which is
Wrapper for a JSP or other resource within the same web application. Exposes model objects as request attributes and forwards the request to the specified resource URL using a javax.servlet.RequestDispatcher.
A URL for this view is supposed to specify a resource within the web application, suitable for RequestDispatcher's forward or include method.
Emphasis mine. In other words, the view, before rendering, will try to get a RequestDispatcher
to which to forward()
. Before doing this it checks the following
if (path.startsWith("/") ? uri.equals(path) : uri.equals(StringUtils.applyRelativePath(uri, path))) {
throw new ServletException("Circular view path [" + path + "]: would dispatch back " +
"to the current handler URL [" + uri + "] again. Check your ViewResolver setup! " +
"(Hint: This may be the result of an unspecified view, due to default view name generation.)");
}
where path
is the view name, what you returned from the @Controller
. In this example, that is preference
. The variable uri
holds the uri of the request being handled, which is /context/preference
.
The code above realizes that if you were to forward to /context/preference
, the same servlet (since the same handled the previous) would handle the request and you would go into an endless loop.
When you declare a ThymeleafViewResolver
and a ServletContextTemplateResolver
with a specific prefix
and suffix
, it builds the View
differently, giving it a path like
WEB-INF/web-templates/preference.html
ThymeleafView
instances locate the file relative to the ServletContext
path by using a
ServletContextResourceResolver
templateInputStream = resourceResolver.getResourceAsStream(templateProcessingParameters, resourceName);`
which eventually
return servletContext.getResourceAsStream(resourceName);
This gets a resource that is relative to the ServletContext
path. It can then use the TemplateEngine
to generate the HTML. There's no way an endless loop can happen here.
Change to,

Another very simple way to estimate the sharpness of an image is to use a Laplace (or LoG) filter and simply pick the maximum value. Using a robust measure like a 99.9% quantile is probably better if you expect noise (i.e. picking the Nth-highest contrast instead of the highest contrast.) If you expect varying image brightness, you should also include a preprocessing step to normalize image brightness/contrast (e.g. histogram equalization).
I've implemented Simon's suggestion and this one in Mathematica, and tried it on a few test images:
The first test blurs the test images using a Gaussian filter with a varying kernel size, then calculates the FFT of the blurred image and takes the average of the 90% highest frequencies:
testFft[img_] := Table[
(
blurred = GaussianFilter[img, r];
fft = Fourier[ImageData[blurred]];
{w, h} = Dimensions[fft];
windowSize = Round[w/2.1];
Mean[Flatten[(Abs[
fft[[w/2 - windowSize ;; w/2 + windowSize,
h/2 - windowSize ;; h/2 + windowSize]]])]]
), {r, 0, 10, 0.5}]
Result in a logarithmic plot:
The 5 lines represent the 5 test images, the X axis represents the Gaussian filter radius. The graphs are decreasing, so the FFT is a good measure for sharpness.
This is the code for the "highest LoG" blurriness estimator: It simply applies an LoG filter and returns the brightest pixel in the filter result:
testLaplacian[img_] := Table[
(
blurred = GaussianFilter[img, r];
Max[Flatten[ImageData[LaplacianGaussianFilter[blurred, 1]]]];
), {r, 0, 10, 0.5}]
Result in a logarithmic plot:
The spread for the un-blurred images is a little better here (2.5 vs 3.3), mainly because this method only uses the strongest contrast in the image, while the FFT is essentially a mean over the whole image. The functions are also decreasing faster, so it might be easier to set a "blurry" threshold.
You might want to use filter()
available as the built-in.

Java does not truely support multidimensional arrays. In Java, a two-dimensional array is simply an array of arrays, a three-dimensional array is an array of arrays of arrays, a four-dimensional array is an array of arrays of arrays of arrays, and so on...
We can define a two-dimensional array as:
int[ ] num[ ] = {{1,2}, {1,2}, {1,2}, {1,2}}
int[ ][ ] num = new int[4][2]
num[0][0] = 1;
num[0][1] = 2;
num[1][0] = 1;
num[1][1] = 2;
num[2][0] = 1;
num[2][1] = 2;
num[3][0] = 1;
num[3][1] = 2;
If you don't allocate, let's say num[2][1]
, it is not initialized and then it is automatically allocated 0, that is, automatically num[2][1] = 0
;
Below, num1.length
gives you rows.
While num1[0].length
gives you the number of elements related to num1[0]
. Here num1[0]
has related arrays num1[0][0]
and num[0][1]
only.
Here we used a for
loop which helps us to calculate num1[i].length
. Here i
is incremented through a loop.
class array
{
static int[][] add(int[][] num1,int[][] num2)
{
int[][] temp = new int[num1.length][num1[0].length];
for(int i = 0; i<temp.length; i++)
{
for(int j = 0; j<temp[i].length; j++)
{
temp[i][j] = num1[i][j]+num2[i][j];
}
}
return temp;
}
public static void main(String args[])
{
/* We can define a two-dimensional array as
1. int[] num[] = {{1,2},{1,2},{1,2},{1,2}}
2. int[][] num = new int[4][2]
num[0][0] = 1;
num[0][1] = 2;
num[1][0] = 1;
num[1][1] = 2;
num[2][0] = 1;
num[2][1] = 2;
num[3][0] = 1;
num[3][1] = 2;
If you don't allocate let's say num[2][1] is
not initialized, and then it is automatically
allocated 0, that is, automatically num[2][1] = 0;
3. Below num1.length gives you rows
4. While num1[0].length gives you number of elements
related to num1[0]. Here num1[0] has related arrays
num1[0][0] and num[0][1] only.
5. Here we used a 'for' loop which helps us to calculate
num1[i].length, and here i is incremented through a loop.
*/
int num1[][] = {{1,2},{1,2},{1,2},{1,2}};
int num2[][] = {{1,2},{1,2},{1,2},{1,2}};
int num3[][] = add(num1,num2);
for(int i = 0; i<num1.length; i++)
{
for(int j = 0; j<num1[j].length; j++)
System.out.println("num3[" + i + "][" + j + "]=" + num3[i][j]);
}
}
}
A more modern approach using Promise and async/await :
toDataURL(url) {
return fetch(url).then((response) => {
return response.blob();
}).then(blob => {
return URL.createObjectURL(blob);
});
}
then
async download() {
const a = document.createElement("a");
a.href = await toDataURL("https://cdn1.iconfinder.com/data/icons/ninja-things-1/1772/ninja-simple-512.png");
a.download = "myImage.png";
document.body.appendChild(a);
a.click();
document.body.removeChild(a);
}

Use inputstream once don't use it multiple times and Do inputstream.close()
You already get the next line in this line of your code:
String line = sc.nextLine();
To get the words of a line, I would recommend to use:
String[] words = line.split(" ");
You can use Twilio for this. But if you are looking for some tricky workaround you can follow the workaround I have mentioned below.
This is not possible for receiving sms. But this is a tricky method you can use to send sms to number of clients. You can use twitter API. We can follow twitter account from our mobile phone with a sms. We just have to send sms to twitter. Imagine we create a twitter account with the user name of @username
. Then we can send sms to 40404 as shown below.
follow @username
Then we start to get tweets which are tweeted in that account.
So after we create a twitter account then we can use Twitter API to post tweets from that account. Then all the clients who have follow that account as I mentioned before start to receiving tweets.
You can learn how to post tweets with twitter API from following link.
Before you start developing you have to get permission to use twitter api. You can get access to twitter api from following link.
This is not the best solution for your problem.But hope this help.
Well, the shortest way I know of, is following:
psql -U {user_name} -d {database_name} -f {file_path} -h {host_name}
database_name: Which database should you insert your file data in.
file_path: Absolute path to the file through which you want to perform the importing.
host_name: The name of the host. For development purposes, it is mostly localhost
.
Upon entering this command in console, you will be prompted to enter your password.

With about 100 lines of code ;-) Here is an example.
The main point: Unlike with other JDBC drivers, the one from Oracle doesn't support using Reader
and InputStream
as parameters of an INSERT
. Instead, you must SELECT
the CLOB
column FOR UPDATE
and then write into the ResultSet
I suggest that you move this code into a helper method/class. Otherwise, it will pollute the rest of your code.
Just use the JSON.stringify method and pass it through as the "data" parameter for the $.ajax function, like follows:
$.ajax({
type: "POST",
url: "index.php",
dataType: "json",
data: JSON.stringify({ paramName: info }),
success: function(msg){
$('.answer').html(msg);
}
});
You just need to make sure you include the JSON2.js file in your page...
console.log()

:Here is the difference in a nutshell:
console.log(input)
: The browser logs in a nicely formatted mannerconsole.dir(input)
: The browser logs just the object with all its propertiesThe following code:
let obj = {a: 1, b: 2};
let DOMel = document.getElementById('foo');
let arr = [1,2,3];
console.log(DOMel);
console.dir(DOMel);
console.log(obj);
console.dir(obj);
console.log(arr);
console.dir(arr);

We need the primary key of that particular model that you want to update. For example:
private fun update(Name: String?, Brand: String?) {

if (deviceEntity == null)
remoteDao?.insertDevice(DeviceEntity(DeviceModel = DeviceName, DeviceBrand = DeviceBrand))
else

}
In this function, I am checking whether a particular entry exists in the database if exists pull the primary key which is id over here and perform update function.
This is the for fetching and update records:
@Query("SELECT * FROM ${DeviceDatabase.DEVICE_TABLE_NAME} WHERE ${DeviceDatabase.COLUMN_DEVICE_ID} = :DeviceId LIMIT 1")
fun getRemoteDeviceId(DeviceId: String?): DeviceEntity
@Update(onConflict = OnConflictStrategy.REPLACE)
fun updatDevice(item: DeviceEntity): Int
With Vagrant now you can have Docker as a provider. http://docs.vagrantup.com/v2/docker/. Docker provider can be used instead of VirtualBox or VMware.
Please note that you can also use Docker for provisioning with Vagrant. This is very different than using Docker as a provider. http://docs.vagrantup.com/v2/provisioning/docker.html
This means you can replace Chef or Puppet with Docker. You can use combinations like Docker as provider (VM) with Chef as provisioner. Or you can use VirtualBox as provider and Docker as provisioner.
After digging around a bit, i found this. It seems to be the answer:
Updated (11/April/2018)
Facebook change announce (10/04/2018)
Facebook updated token expiration page (10/04/2018)
offline_access: Enables your application to perform authorized requests on behalf of the user at any time. By default, most access tokens expire after a short time period to ensure applications only make requests on behalf of the user when the are actively using the application. This permission makes the access token returned by our OAuth endpoint long-lived.
Its a permission value requested.

UPDATE
offline_access permission has been removed a while ago.

You can also take a look at Timer
and TimerTask
classes which you can use to schedule your task to run every n
seconds.
You need a class that extends TimerTask
and override the public void run()
method, which will be executed everytime you pass an instance of that class to timer.schedule()
method..
Here's an example, which prints Hello World
every 5 seconds: -
class SayHello extends TimerTask {
public void run() {
System.out.println("Hello World!");
}
}
// And From your main() method or any other method
Timer timer = new Timer();
timer.schedule(new SayHello(), 0, 5000);
I had the same problem, it was a missing manifest.json file, if not found the browser decide with orientation is best fit, if you don't specify the file or use a wrong path.
I fixed just calling the manifest.json correctly on html headers.
My html headers:
<meta name="application-name" content="App Name">
<meta name="mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<link rel="manifest" href="manifest.json">
<meta name="msapplication-starturl" content="/">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta name="theme-color" content="#">
<meta name="msapplication-TileColor" content="#">
<meta name="msapplication-config" content="browserconfig.xml">
<link rel="icon" type="image/png" sizes="192x192" href="android-chrome-192x192.png">
<link rel="apple-touch-icon" sizes="180x180" href="apple-touch-icon.png">
<link rel="mask-icon" href="safari-pinned-tab.svg" color="#ffffff">
<link rel="shortcut icon" href="favicon.ico">
And the manifest.json file content:
{
"display": "standalone",
"orientation": "portrait",
"start_url": "/",
"theme_color": "#000000",
"background_color": "#ffffff",
"icons": [
{
"src": "android-chrome-192x192.png",
"sizes": "192x192",
"type": "image/png"
}
}
To generate your favicons and icons use this webtool: https://realfavicongenerator.net/
To generate your manifest file use: https://tomitm.github.io/appmanifest/
My PWA Works great, hope it helps!
[Route("api/controller/{one}/{two}")]
public string Get(int One, int Two)
{
return "both params of the root link({one},{two}) and Get function parameters (one, two) should be same ";
}
Both params of the root link({one},{two}) and Get function parameters (one, two) should be same
If you have named tuples you can do this:
results = [t.age for t in mylist if t.person_id == 10]
Otherwise use indexes:
results = [t[1] for t in mylist if t[0] == 10]
Or use tuple unpacking as per Nate's answer. Note that you don't have to give a meaningful name to every item you unpack. You can do (person_id, age, _, _, _, _)
to unpack a six item tuple.
abs()
is for integers only. For floating point, use fabs()
(or one of the fabs()
line with the correct precision for whatever a actually is)
You're checking if the result of IndexOf is larger or equal 0, meaning whether the match starts anywhere in the string. Try checking if it's equal to 0:
if (testList.FindAll(x => x.IndexOf(keyword,
StringComparison.OrdinalIgnoreCase) >= 0).Count > 0)
Console.WriteLine("Found in list");
Now "goat" and "oat" won't match, but "goat" and "goa" will. To avoid this, you can compare the lenghts of the two strings.
To avoid all this complication, you can use a dictionary instead of a list. They key would be the lowercase string, and the value would be the real string. This way, performance isn't hurt because you don't have to use ToLower
for each comparison, but you can still use Contains
.
The route-map express example matches url paths with objects which in turn matches http verbs with functions. This lays the routing out in a tree, which is concise and easy to read. The apps's entities are also written as objects with the functions as enclosed methods.
var express = require('../../lib/express')
, verbose = process.env.NODE_ENV != 'test'
, app = module.exports = express();
app.map = function(a, route){
route = route || '';
for (var key in a) {
switch (typeof a[key]) {
// { '/path': { ... }}
case 'object':
app.map(a[key], route + key);
break;
// get: function(){ ... }
case 'function':
if (verbose) console.log('%s %s', key, route);
app[key](route, a[key]);
break;
}
}
};
var users = {
list: function(req, res){
res.send('user list');
},
get: function(req, res){
res.send('user ' + req.params.uid);
},
del: function(req, res){
res.send('delete users');
}
};
var pets = {
list: function(req, res){
res.send('user ' + req.params.uid + '\'s pets');
},
del: function(req, res){
res.send('delete ' + req.params.uid + '\'s pet ' + req.params.pid);
}
};
app.map({
'/users': {
get: users.list,
del: users.del,
'/:uid': {
get: users.get,
'/pets': {
get: pets.list,
'/:pid': {
del: pets.del
}
}
}
}
});
app.listen(3000);
I know it's a bit late and maybe you already, indirectly, said it, but again, Kafka is not a queue at all, it's a log (as someone said above, poll based).
To make it simple, the most obvious use case when you should prefer RabbitMQ (or any queue techno) over Kafka is the following one :
You have multiple consumers consuming from a queue and whenever there is a new message in the queue and an available consumer, you want this message to be processed. If you look closely at how Kafka works, you'll notice it does not know how to do that, because of partition scaling, you'll have a consumer dedicated to a partition and you'll get into starvation issue. Issue that is easily avoided by using simple queue techno. You can think of using a thread that will dispatch the different messages from same partition, but again, Kafka does not have any selective acknowledgment mechanisms.
The most you could do is doing as those guys and try to transform Kafka as a queue : https://github.com/softwaremill/kmq
Yannick
You might want to try kt. It's also quite faster than the bundled kafka-topics
.
This is the current most complete info description you can get out of a topic with kt:
kt topic -brokers localhost:9092 -filter my_topic_name -partitions -leaders -replicas
It also outputs as JSON, so you can pipe it to jq
for further flexibility.
@Leniel this method is good but you need to add width to all the floating div's. I would say make them equal width or assign fixed width. Something like
.content-wrapper > div { width:33.3%; }
you may assign class names to each div rather than adding inline style
, which is not a good practice.
Be sure to use a clearfix div or clear div to avoid following content remains below these div's.
You can find details of how to use clearfix div here
Try in html:
style="display: inline-block; margin-top: 50px;"
or in css:
display: inline-block;
margin-top: 50px;
The solutions of Fabricio works just fine.
A very common usecase of calc is add 100% width and adding some margin around the element.
One can do so with:
@someMarginVariable: 15px;
margin: @someMarginVariable;
width: calc(~"100% - "@someMarginVariable*2);
width: -moz-calc(~"100% - "@someMarginVariable*2);
width: -webkit-calc(~"100% - "@someMarginVariable*2);
width: -o-calc(~"100% - "@someMarginVariable*2);
Or can use a mixin like:
.fullWidthMinusMarginPaddingMixin(@marginSize,@paddingSize) {
@minusValue: (@marginSize+@paddingSize)*2;
padding: @paddingSize;
margin: @marginSize;
width: calc(~"100% - "@minusValue);
width: -moz-calc(~"100% - "@minusValue);
width: -webkit-calc(~"100% - "@minusValue);
width: -o-calc(~"100% - "@minusValue);
}
It's an encoding error - so if it's a unicode string, this ought to fix it:
text.encode("windows-1252").decode("utf-8")
If it's a plain string, you'll need an extra step:
text.decode("utf-8").encode("windows-1252").decode("utf-8")
Both of these will give you a unicode string.
By the way - to discover how a piece of text like this has been mangled due to encoding issues, you can use chardet:
>>> import chardet
>>> chardet.detect(u"And the Hip’s coming, too")
{'confidence': 0.5, 'encoding': 'windows-1252'}
You are right - you declared a new use defined type (Name_pairs) and you need variable of that type to use it.
The code should go like this:
Name_pairs np;
np.read_names()
Hands down the easiest way to parse a HTML table is to use pandas.read_html() - it accepts both URLs and HTML.
import pandas as pd
url = r'https://en.wikipedia.org/wiki/List_of_S%26P_500_companies'
tables = pd.read_html(url) # Returns list of all tables on page
sp500_table = tables[0] # Select table of interest
Only downside is that read_html()
doesn't preserve hyperlinks.
A different take on authentication is Passwordless, a token-based authentication module for express that circumvents the inherent problem of passwords [1]. It's fast to implement, doesn't require too many forms, and offers better security for the average user (full disclosure: I'm the author).
You can obtain all jQuery events using $._data($('[selector]')[0],'events'); change [selector] to what you need.
There is a plugin that gather all events attached by jQuery called eventsReport.
Also i write my own plugin that do this with better formatting.
But anyway it seems we can't gather events added by addEventListener method. May be we can wrap addEventListener call to store events added after our wrap call.
It seems the best way to see events added to an element with dev tools.
But you will not see delegated events there. So there we need jQuery eventsReport.
UPDATE: NOW We CAN see events added by addEventListener method SEE RIGHT ANSWER TO THIS QUESTION.
Try this. It holds the color until another item is clicked.
<style type="text/css">
.activeElem{
background-color:lightblue
}
.desactiveElem{
background-color:none
}
}
</style>
<script type="text/javascript">
var activeElemId;
function activateItem(elemId) {
document.getElementById(elemId).className="activeElem";
if(null!=activeElemId) {
document.getElementById(activeElemId).className="desactiveElem";
}
activeElemId=elemId;
}
</script>
<li id="aaa"><a href="#" onclick="javascript:activateItem('aaa');">AAA</a>
<li id="bbb"><a href="#" onClick="javascript:activateItem('bbb');">BBB</a>
<li id="ccc"><a href="#" onClick="javascript:activateItem('ccc');">CCC</a>
Its possible, but not directly.
In short, go to the search, use your regex, check "mark line" and click "Find all". It results in bookmarks for all those lines.
In the search menu there is a point "delete bookmarked lines" voila.
I found the answer here (the correct answer is the second one, not the accepted!): How to delete specific lines on Notepad++?
I used following command in MySQL command-line to restore a MySQL database which size more than 7GB, and it works.
set global max_allowed_packet=268435456;
Find log enabled or not?
SHOW VARIABLES LIKE '%log%';
Set the logs:-
SET GLOBAL general_log = 'ON';
SET GLOBAL slow_query_log = 'ON';
adding below lines of code in build.gradel file worked for me, add them under buildTypes block below release as shown
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
applicationIdSuffix ".debug"
debuggable true
}
As Alex noted you can use jQuery offset() to get the position relative to the document flow. Use position() for its x,y coordinates relative to the parent.
EDIT: Switched document.ready
for window.load
because load
waits for all of the elements so you get their size instead of simply preparing the DOM. In my experience, load
results in fewer incorrectly Javascript positioned elements.
$(window).load(function(){
// Log the position with jQuery
var position = $('#myDivInQuestion').position();
console.log('X: ' + position.left + ", Y: " + position.top );
});
For angular v1.2.26, none of the above works. An ng-click that calls the above methods will have to be clicked twice in order to make the state reload.
So I ended up emulating 2 clicks using $timeout.
$provide.decorator('$state',
["$delegate", "$stateParams", '$timeout', function ($delegate, $stateParams, $timeout) {
$delegate.forceReload = function () {
var reload = function () {
$delegate.transitionTo($delegate.current, angular.copy($stateParams), {
reload: true,
inherit: true,
notify: true
})
};
reload();
$timeout(reload, 100);
};
return $delegate;
}]);
I added this to my .bashrc
function npmv {
case $# in # number of arguments passed
0) v="$(npm -v)" ; #store output from npm -v in variable
echo "NPM version is: $v"; #can't use single quotes
#${v} would also work
;;
1) s="$(npm list --depth=0 $1 | grep $1 | cut -d @ -f 2)";
echo "$s";
;;
2) case "$2" in # second argument
g) #global|#Syntax to compare bash string to literal
s="$(npm list --depth=0 -g $1 | grep $1 | cut -d @ -f 2)";
echo "$s";
;;
l) #latest
npm view $1 version; #npm info $1 version does same thing
;;
*) echo 'Invalid arguments';
;;
esac;
;;
*) echo 'Invalid arguments';
;;
esac;
}
export -f npmv
Now all I have to do is type:
NPM version is: 4.2.0
0.8.08
0.8.09
0.8.10
Note -d on cut command means delimit by, followed by @, then f means field the 2 means second field since there will be one either side of the @ symbol.
varchar(10) will store 10 characters, which may be more than 10 bytes. In indexes, it will allocate the maximium length of the field - so if you are using UTF8-mb4, it will allocate 40 bytes for the 10 character field.
Extending other answers:
I found @GEverding's answer most flexible. It also works with aggregation:
test_db.js
print("name,email");
db.users.aggregate([
{ $match: {} }
]).forEach(function(user) {
print(user.name+","+user.email);
}
});
Execute the following command to export results:
mongo test_db < ./test_db.js >> ./test_db.csv
Unfortunately, it adds additional text to the CSV file which requires processing the file before we can use it:
MongoDB shell version: 3.2.10
connecting to: test_db
But we can make mongo shell stop spitting out those comments and only print what we have asked for by passing the --quiet
flag
mongo --quiet test_db < ./test_db.js >> ./test_db.csv
Use vector::front
, it should be the most portable solution. I've used this when I'm interfacing with a fixed API that wants a char ptr. Example:
void funcThatTakesCharPtr(char* start, size_t size);
...
void myFunc(vector<char>& myVec)
{
// Get a pointer to the front element of my vector:
char* myDataPtr = &(myVec.front());
// Pass that pointer to my external API:
funcThatTakesCharPtr(myDataPtr, myVec.size());
}
Update 1: It is possible for different users to have different path. But its not the likely problem here. There is more chance that the user that the iwam user doesn't have permission to the oracle client directory.
Update 0: Its suppose to work. Check for environment variable ( That are needed to find the oracle client and tnsnames.ora ). Also, Maybe you have a 32/64 bit issues. Also, consider using the Oracle Data Provider for .NET ( search for odp.net)
On debian 7.5 I got the same error. I realized the /tmp
folder owner and permissions were off. As another answer suggested I did as follows (must be root):

I did not even have to restart mysql daemon.
Jlordo approach covers specific situation. If you try to build an abstract method out of it, you can face a difficulty to check if 'textFrom
' is before 'textTo
'. Otherwise method can return a match for some other occurance of 'textFrom
' in text.
Here is a ready-to-go abstract method that covers this disadvantage:
/**
* Get text between two strings. Passed limiting strings are not
* included into result.
*
* @param text Text to search in.
* @param textFrom Text to start cutting from (exclusive).
* @param textTo Text to stop cuutting at (exclusive).
*/
public static String getBetweenStrings(
String text,
String textFrom,
String textTo) {
String result = "";
// Cut the beginning of the text to not occasionally meet a
// 'textTo' value in it:
result =
text.substring(
text.indexOf(textFrom) + textFrom.length(),
text.length());
// Cut the excessive ending of the text:
result =
result.substring(
0,
result.indexOf(textTo));
return result;
}
$first = doubleval($_POST['first']);
$second = doubleval($_POST['second']);
if($_POST['group1'] == 'add') {
echo "$first + $second = ".($first + $second);
}
// etc
foo = [1, 2, 3]
bar = [4, 5, 6]
foo.append(bar) --> [1, 2, 3, [4, 5, 6]]
foo.extend(bar) --> [1, 2, 3, 4, 5, 6]
Assuming your controller's action method is something like this:
public ActionResult AllCategories(int id = 0)
{
return View(db.Categories.Include(p => p.Products).ToList());
}
Modify your models to be something like this:
public class Product
{
[Key]
public int ID { get; set; }
public int CategoryID { get; set; }
//new code
public virtual Category Category { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public string Path { get; set; }
//remove code below
//public virtual ICollection<Category> Categories { get; set; }
}
public class Category
{
[Key]
public int CategoryID { get; set; }
public string Name { get; set; }
//new code
public virtual ICollection<Product> Products{ get; set; }
}
Then your since now the controller takes in a Category as Model (instead of a Product):
foreach (var category in Model)
{
<h3><u>@category.Name</u></h3>
<div>
<ul>
@foreach (var product in Model.Products)
{
// cut for brevity, need to add back more code from original
<li>@product.Title</li>
}
</ul>
</div>
}
UPDATED: Add ToList() to the controller return statement.
Using quicktype, you can generate C++ serializers and deserializers from JSON sample data.
For example, given the sample JSON:
{
"breed": "Boxer",
"age": 5,
"tail_length": 6.5
}
quicktype generates:
#include "json.hpp"
namespace quicktype {
using nlohmann::json;
struct Dog {
int64_t age;
std::string breed;
double tail_length;
};
inline json get_untyped(const json &j, const char *property) {
if (j.find(property) != j.end()) {
return j.at(property).get<json>();
}
return json();
}
}
namespace nlohmann {
inline void from_json(const json& _j, struct quicktype::Dog& _x) {
_x.age = _j.at("age").get<int64_t>();
_x.breed = _j.at("breed").get<std::string>();
_x.tail_length = _j.at("tail_length").get<double>();
}
inline void to_json(json& _j, const struct quicktype::Dog& _x) {
_j = json{{"age", _x.age}, {"breed", _x.breed}, {"tail_length", _x.tail_length}};
}
}
To parse the Dog JSON data, include the code above, install Boost and json.hpp, then do:
Dog dog = nlohmann::json::parse(jsonString);
Putting this question in the context of NIO and NIO.2 in java 7, async IO is one step more advanced than non-blocking.
With java NIO non-blocking calls, one would set all channels (SocketChannel, ServerSocketChannel, FileChannel, etc) as such by calling AbstractSelectableChannel.configureBlocking(false)
.
After those IO calls return, however, you will likely still need to control the checks such as if and when to read/write again, etc.
For instance,
while (!isDataEnough()) {
socketchannel.read(inputBuffer);
// do something else and then read again
}
With the asynchronous api in java 7, these controls can be made in more versatile ways.
One of the 2 ways is to use CompletionHandler
. Notice that both read
calls are non-blocking.
asyncsocket.read(inputBuffer, 60, TimeUnit.SECONDS /* 60 secs for timeout */,
new CompletionHandler<Integer, Object>() {
public void completed(Integer result, Object attachment) {...}
public void failed(Throwable e, Object attachment) {...}
}
}
JOptionPane.showInternalInputDialog probably does what you want. If not, it would be helpful to understand what it is missing.
Faced the same Issue. I had an assosciation between 2 beans. In bean A I had defined the variable type as Integer and in bean B I had defined the same variable as Long. I changed both of them to Integer. This solved my issue.
I could fix it by changing it to
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
}
in build.gradle file
What about
somenumber == Math.Max(0,Math.Min(10,somenumber));
returns true when somenumber is 5. returns false when somenumber is 11.
As the bError = false
statement is never reached in the try block
, and the statement is struck to the input taken, it keeps printing the error in infinite loop.
Try using it this way by using hasNextInt()
catch (Exception e) {
System.out.println("Error!");
input.hasNextInt();
}
Or try using nextLine()
coupled with Integer.parseInt()
for taking input....
Scanner scan = new Scanner(System.in);
int num1 = Integer.parseInt(scan.nextLine());
int num2 = Integer.parseInt(scan.nextLine());
Here's somewhat simpler collector than proposed by @EmmanuelTouzery. Use it if you like:
public static <T, K, U> Collector<T, ?, Map<K, U>> toMapNullFriendly(
Function<? super T, ? extends K> keyMapper,
Function<? super T, ? extends U> valueMapper) {
@SuppressWarnings("unchecked")
U none = (U) new Object();
return Collectors.collectingAndThen(
Collectors.<T, K, U> toMap(keyMapper,
valueMapper.andThen(v -> v == null ? none : v)), map -> {
map.replaceAll((k, v) -> v == none ? null : v);
return map;
});
}
We just replace null
with some custom object none
and do the reverse operation in the finisher.
If you want the file to be opened with the default application, I mean without specifying Acrobat or Reader, you can't open the file in the specified page.
On the other hand, if you are Ok with specifying Acrobat or Reader, keep reading:
You can do it without telling the full Acrobat path, like this:
Process myProcess = new Process();
myProcess.StartInfo.FileName = "acroRd32.exe"; //not the full application path
myProcess.StartInfo.Arguments = "/A \"page=2=OpenActions\" C:\\example.pdf";
myProcess.Start();
If you don't want the pdf to open with Reader but with Acrobat, chage the second line like this:
myProcess.StartInfo.FileName = "Acrobat.exe";
You can query the registry to identify the default application to open pdf files and then define FileName on your process's StartInfo accordingly.
Follow this question for details on doing that: Finding the default application for opening a particular file type on Windows
Using contains didn't work well for my string with special characters. Find worked though.
df[df['A'].str.find("hello") != -1]
There is plugin called Partial Diff which helps to compare text selections within a file, across different files, or to the clipboard.
A good approach is to use a mixin to control stroke colour and fill colour. My svgs are used as icons.
@mixin icon($color, $hoverColor) {
svg {
fill: $color;
circle, line, path {
fill: $color
}
&:hover {
fill: $hoverColor;
circle, line, path {
fill: $hoverColor;
}
}
}
}
You can then do the following in your scss:
.container {
@include icon(white, blue);
}
Use the Java 8 way of converting a Map<String, Object>
to Map<String, String>
. This solution handles null
values.
Map<String, String> keysValuesStrings = keysValues.entrySet().stream()
.filter(entry -> entry.getValue() != null)
.collect(Collectors.toMap(Entry::getKey, entry -> entry.getValue().toString()));
You (or Joomla) is likely including this file multiple times. Enclose your function in a conditional block:
if (!function_exists('parseDate')) {
// ... proceed to declare your function
}
Since many browsers block popups by default and popups are really ugly, I recommend using lightbox or thickbox.
They are prettier and are not popups. They are extra HTML markups that are appended to your document's body with the appropriate CSS content.
I was impatient and chose not to wait for answers... for reference it doesn't look that hard to do something like this (which works for my application, I don't need to worry about escaped quotes, as the stuff in quotes is limited to a few constrained forms):
final static private Pattern splitSearchPattern = Pattern.compile("[\",]");
private List<String> splitByCommasNotInQuotes(String s) {
if (s == null)
return Collections.emptyList();
List<String> list = new ArrayList<String>();
Matcher m = splitSearchPattern.matcher(s);
int pos = 0;
boolean quoteMode = false;
while (m.find())
{
String sep = m.group();
if ("\"".equals(sep))
{
quoteMode = !quoteMode;
}
else if (!quoteMode && ",".equals(sep))
{
int toPos = m.start();
list.add(s.substring(pos, toPos));
pos = m.end();
}
}
if (pos < s.length())
list.add(s.substring(pos));
return list;
}
(exercise for the reader: extend to handling escaped quotes by looking for backslashes also.)
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'"

I'm able to modify a script variable value by assignment in the Console. Seems simplest.
git version 2.16.1.windows.4
Just doing a git fetch remoteRepositoryName branchName (eg: git fetch origin my_local_branch)
is enough. Fetch will be done and a new local branch will be created with the same name and tracking will be set to remote branch.
Then perform git checkout branchName
Assuming the string is called myStr:
// Strip start and end quotation mark and possible initial comma
myStr=myStr.replace(/^,?'/,'').replace(/'$/,'');
// Split stripping quotations
myArray=myStr.split("','");
Note that if a string can be missing in the list without even having its quotation marks present and you want an empty spot in the corresponding location in the array, you'll need to write the splitting manually for a robust solution.
Not applicable in most circumstances, but I had lots of async scripts running in the browser and as a hack I do
window.reload();
to stop everything.
