The following code results in the error below:
pd.set_option('display.max_colwidth', -1)
FutureWarning: Passing a negative integer is deprecated in version 1.0 and will not be supported in future version. Instead, use None to not limit the column width.
Instead, use:
pd.set_option('display.max_colwidth', None)
This accomplishes the task and complies with versions of pandas following version 1.0.

If you simply need a new byte array, then use the following:
byte[] Combine(byte[] a1, byte[] a2, byte[] a3)
{
byte[] ret = new byte[a1.Length + a2.Length + a3.Length];
Array.Copy(a1, 0, ret, 0, a1.Length);
Array.Copy(a2, 0, ret, a1.Length, a2.Length);
Array.Copy(a3, 0, ret, a1.Length + a2.Length, a3.Length);
return ret;
}
Alternatively, if you just need a single IEnumerable, consider using the C# 2.0 yield operator:
IEnumerable<byte> Combine(byte[] a1, byte[] a2, byte[] a3)
{
foreach (byte b in a1)
yield return b;
foreach (byte b in a2)
yield return b;
foreach (byte b in a3)
yield return b;
}
Not sure I fully understand your question, but is this what you want to do?

Because $
does not work on atomic vectors. Use [
or [[
instead. From the help file for $
:
The default methods work somewhat differently for atomic vectors, matrices/arrays and for recursive (list-like, see is.recursive) objects. $ is only valid for recursive objects, and is only discussed in the section below on recursive objects.
x[["ed"]]
will work.
I would suggest using absolute positioning within the element.
I've created this to help you visualize it a bit.

You are trying to get width and height of an elements, that weren't drawn yet.
If you use debug and stop at some point, you'll see, that your device screen is still empty, that's because your elements weren't drawn yet, so you can't get width and height of something, that doesn't yet exist.
And, I might be wrong, but setWidth()
is not always respected, Layout
lays out it's children and decides how to measure them (calling child.measure()
), so If you set setWidth()
, you are not guaranteed to get this width after element will be drawn.
What you need, is to use getMeasuredWidth()
(the most recent measure of your View) somewhere after the view was actually drawn.
Look into Activity
lifecycle for finding the best moment.
http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle
I believe a good practice is to use OnGlobalLayoutListener
like this:
yourView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
if (!mMeasured) {
// Here your view is already layed out and measured for the first time
mMeasured = true; // Some optional flag to mark, that we already got the sizes
}
}
});
You can place this code directly in onCreate()
, and it will be invoked when views will be laid out.
You need to pass a function pointer. The syntax is a little cumbersome, but it's really powerful once you get familiar with it.
contentType: 'application/x-www-form-urlencoded'
Use hard links instead. This differs from a soft (symbolic) link. All programs, including git
will treat the file as a regular file. Note that the contents can be modified by changing either the source or the destination.
If you already have git and Xcode installed, install hardlink. It's a microscopic tool to create hard links.
To create the hard link, simply:
hln source destination
Does Apple File System support directory hard links?
Directory hard links are not supported by Apple File System. All directory hard links are converted to symbolic links or aliases when you convert from HFS+ to APFS volume formats on macOS.
Follow https://github.com/selkhateeb/hardlink/issues/31 for future alternatives.
The ln
command can make hard links:
ln source destination
Use mklink to create a junction on Windows:
mklink /j "source" "destination"
Just set offset for UIBarButtonItem appearance.
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(-1000, -1000)

As one person may have already suggested,
I passed the ISO 8601 date string directly to moment like so...
`moment.utc('2019-11-03T05:00:00.000Z').format('MM/DD/YYYY')`
or
`moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')`
either of these solutions will give you the same result.
`console.log(moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')) // 11/3/2019`

When you use the url tag you should use quotes for string literals, for example:

I had a similar issue but I was unable to use the UserAgent
class inside the fake_useragent
module. I was running the code inside a docker container
import requests
import ujson
import random
response = requests.get('https://fake-useragent.herokuapp.com/browsers/0.1.11')
agents_dictionary = ujson.loads(response.text)
random_browser_number = str(random.randint(0, len(agents_dictionary['randomize'])))
random_browser = agents_dictionary['randomize'][random_browser_number]
user_agents_list = agents_dictionary['browsers'][random_browser]
user_agent = user_agents_list[random.randint(0, len(user_agents_list)-1)]
I targeted the endpoint used in the module. This solution still gave me a random user agent however there is the possibility that the data structure at the endpoint could change.
If you have additional types, edit the selector:
var formElements = new Array();
$("form :input").each(function(){
formElements.push($(this));
});
All form elements are now in the array formElements.
Number(new Date(2010, 6, 26))
Works the same way as things above. If you need seconds don't forget to / 1000
You can easy get that effect without using jQueryUI, for example:
$(document).ready(function(){
$('#slide').click(function(){
var hidden = $('.hidden');
if (hidden.hasClass('visible')){
hidden.animate({"left":"-1000px"}, "slow").removeClass('visible');
} else {
hidden.animate({"left":"0px"}, "slow").addClass('visible');
}
});
});

JSP is s presentation framework, and is generally not supposed to contain any program logic in it. As skaffman suggested, use pure servlets, or any MVC web framework in order to achieve what you want.
This method is the simplest way for beginners to control Layouts rendering in your ASP.NET MVC application. We can identify the controller and render the Layouts as par controller, to do this we can write our code in _ViewStart file in the root directory of the Views folder. Following is an example shows how it can be done.
@{
var controller = HttpContext.Current.Request.RequestContext.RouteData.Values["Controller"].ToString();
string cLayout = "";
if (controller == "Webmaster")
cLayout = "~/Views/Shared/_WebmasterLayout.cshtml";
else
cLayout = "~/Views/Shared/_Layout.cshtml";
Layout = cLayout;
}

UPDATE: From pandas 0.19.2
you can now just pass read_csv()
the url directly, although that will fail if it requires authentication.
For older pandas versions, or if you need authentication, or for any other HTTP-fault-tolerant reason:
Use pandas.read_csv
with a file-like object as the first argument.
If you want to read the csv from a string, you can use io.StringIO
.
For the URL https://github.com/cs109/2014_data/blob/master/countries.csv
, you get html
response, not raw csv; you should use the url given by the Raw
link in the github page for getting raw csv response , which is https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv
Example:
import pandas as pd
import io
import requests
url="https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv"
s=requests.get(url).content
c=pd.read_csv(io.StringIO(s.decode('utf-8')))
Notes:
in Python 2.x, the string-buffer object was StringIO.StringIO
$(document).ready(function () {

});

Using Quick Watch in Visual Studio you can access the LoaderExceptions from ViewDetails of the thrown exception like this:
($exception).LoaderExceptions
You can't break break out of an if statement, unless you use goto.
if (true)
{
int var = 0;
var++;
if (var == 1)
goto finished;
var++;
}
finished:
printf("var = %d\n", var);
This would give "var = 1" as output

My case is the page is sending multiple requests with different parameters when it was open. So most are being "stalled". Following requests immediately sent gets "stalled". Avoiding unnecessary requests would be better (to be lazy...).
Even I faced similar issues. This is how I was able to solve the same
$("#lnkDetails").live('click', function (e) {
//Create dynamic element after the element that raised the event. In my case a <a id="lnkDetails" href="/Attendance/Details/2012-07-01" />
$(this).after('<div id=\"dialog-confirm\" />');
//Optional : Load data from an external URL. The attr('href') is the href of the <a> tag.
$('#dialog-confirm').load($(this).attr('href'));
//Copied from jQueryUI site . Do we need this?
$("#dialog:ui-dialog").dialog("destroy");
//Transform the dynamic DOM element into a dialog
$('#dialog-confirm').dialog({
modal: true,
title: 'Details'
});
//Prevent Bubbling up to other elements.
return false;
});
Also if you want to do that programmatically just add the below line to the onCreate of the activity.
getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE |
WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE );
In my case I had to login to Apple Developer Website and reset the list of devices.

What about [AllowHtml]
attribute above property?
To put code to NPE's answer, I think the most efficient way to do this is:
def insert(originalfile,string):

f2.write(string)
f2.write(f.read())
os.rename('newfile.txt',originalfile)
I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer
Update: This answer gained popularity based on the shell function posted below, which still works as of OSX 10.10 (with the exception of the -g
option).
However, a more fully featured, more robust, tested script version is now available at the npm registry as CLI ttab
, which also supports iTerm2:
If you have Node.js installed, simply run:
npm install -g ttab
(depending on how you installed Node.js, you may have to prepend sudo
).
Otherwise, follow these instructions.
Once installed, run ttab -h
for concise usage information, or man ttab
to view the manual.
Building on the accepted answer, below is a bash convenience function for opening a new tab in the current Terminal window and optionally executing a command (as a bonus, there's a variant function for creating a new window instead).
If a command is specified, its first token will be used as the new tab's title.
# Get command-line help.
newtab -h
# Simpy open new tab.
newtab
# Open new tab and execute command (quoted parameters are supported).
newtab ls -l "$Home/Library/Application Support"
# Open a new tab with a given working directory and execute a command;
# Double-quote the command passed to `eval` and use backslash-escaping inside.
newtab eval "cd ~/Library/Application\ Support; ls"
# Open new tab, execute commands, close tab.
newtab eval "ls \$HOME/Library/Application\ Support; echo Press a key to exit.; read -s -n 1; exit"
# Open new tab and execute script.
newtab /path/to/someScript
# Open new tab, execute script, close tab.
newtab exec /path/to/someScript
# Open new tab and execute script, but don't activate the new tab.
newtab -G /path/to/someScript
CAVEAT: When you run newtab
(or newwin
) from a script, the script's initial working folder will be the working folder in the new tab/window, even if you change the working folder inside the script before invoking newtab
/newwin
- pass eval
with a cd
command as a workaround (see example above).
# Opens a new tab in the current Terminal window and optionally executes a command.
# When invoked via a function named 'newwin', opens a new Terminal *window* instead.
function newtab {
# If this function was invoked directly by a function named 'newwin', we open a new *window* instead
# of a new tab in the existing window.
local funcName=$FUNCNAME
local targetType='tab'
local targetDesc='new tab in the active Terminal window'

# Command-line help.
if [[ "$1" == '--help' || "$1" == '-h' ]]; then
cat <<EOF
Synopsis:
$funcName [-g|-G] [command [param1 ...]]
Description:
Opens a $targetDesc and optionally executes a command.
The new $targetType will run a login shell (i.e., load the user's shell profile) and inherit
the working folder from this shell (the active Terminal tab).
IMPORTANT: In scripts, \`$funcName\` *statically* inherits the working folder from the
*invoking Terminal tab* at the time of script *invocation*, even if you change the
working folder *inside* the script before invoking \`$funcName\`.
-g (back*g*round) causes Terminal not to activate, but within Terminal, the new tab/window
will become the active element.
-G causes Terminal not to activate *and* the active element within Terminal not to change;
i.e., the previously active window and tab stay active.
NOTE: With -g or -G specified, for technical reasons, Terminal will still activate *briefly* when
you create a new tab (creating a new window is not affected).
When a command is specified, its first token will become the new ${targetType}'s title.
Quoted parameters are handled properly.
To specify multiple commands, use 'eval' followed by a single, *double*-quoted string
in which the commands are separated by ';' Do NOT use backslash-escaped double quotes inside
this string; rather, use backslash-escaping as needed.
Use 'exit' as the last command to automatically close the tab when the command
terminates; precede it with 'read -s -n 1' to wait for a keystroke first.
Alternatively, pass a script name or path; prefix with 'exec' to automatically
close the $targetType when the script terminates.
Examples:
$funcName ls -l "\$Home/Library/Application Support"
$funcName eval "ls \\\$HOME/Library/Application\ Support; echo Press a key to exit.; read -s -n 1; exit"
$funcName /path/to/someScript
$funcName exec /path/to/someScript

So here is the scenario that I faced, and how I solved it.
[branch-a]
[Hundreds of commits] -> [R] -> [I]
here R
is the commit that I needed to be removed, and I
is a single commit that comes after R
I made a revert commit and squashed them together
git revert [commit id of R]
git rebase -i HEAD~3
During the interactive rebase squash the last 2 commits.

I love this question - it's like asking "what should I learn first, snowboarding or skiing"? I think it depends if you want to snowboard or to ski. If you want to do both, you have to learn both.
In both sports, you slide down a hill on snow using devices that are sufficiently similar to provoke this question. However, they are also sufficiently different so that learning one does not help you much with the other. Same thing with C and C++. While they appear to be languages sufficiently similar in syntax, the mind set that you need for writing OO code vs procedural code is sufficiently different so that you pretty much have to start from the beginning, whatever language you learn second.

After the docker installation you have 3 networks by default:
docker network ls
NETWORK ID NAME DRIVER SCOPE
f3be8b1ef7ce bridge bridge local
fbff927877c1 host host local
023bb5940080 none null local
I'm trying to keep this simple. So if you start a container by default it will be created inside the bridge (docker0) network.
$ docker run -d jenkins
1498e581cdba jenkins "/bin/tini -- /usr..." 3 minutes ago Up 3 minutes 8080/tcp, 50000/tcp friendly_bell
In the dockerfile of jenkins the ports 8080
and 50000
are exposed. Those ports are opened for the container on its bridge network. So everything inside that bridge network can access the container on port 8080
and 50000
. Everything in the bridge network is in the private range of "Subnet": "172.17.0.0/16",
If you want to access them from the outside you have to map the ports with -p 8080:8080
. This will map the port of your container to the port of your real server (the host network). So accessing your server on 8080
will route to your bridgenetwork on port 8080
.
Now you also have your host network. Which does not containerize the containers networking. So if you start a container in the host network it will look like this (it's the first one):
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1efd834949b2 jenkins "/bin/tini -- /usr..." 6 minutes ago Up 6 minutes eloquent_panini
1498e581cdba jenkins "/bin/tini -- /usr..." 10 minutes ago Up 10 minutes 8080/tcp, 50000/tcp friendly_bell
The difference is with the ports. Your container is now inside your host network. So if you open port 8080
on your host you will acces the container immediately.
$ sudo iptables -I INPUT 5 -p tcp -m tcp --dport 8080 -j ACCEPT
I've opened port 8080
in my firewall and when I'm now accesing my server on port 8080
I'm accessing my jenkins. I think this blog is also useful to understand it better.
In my case the 1 MB maximum cap for data transport by Intent. I'll just use Cache or Storage.
I know 3 way to resolve your problem:
First if you have access to both domains you can allow access for all other domain using :
header("Access-Control-Allow-Origin: *");
or just a domain by adding code bellow to .htaccess file:
<FilesMatch "\.(ttf|otf|eot|woff)$">
<IfModule mod_headers.c>
SetEnvIf Origin "http(s)?://(www\.)?(google.com|staging.google.com|development.google.com|otherdomain.net|dev02.otherdomain.net)$" AccessControlAllowOrigin=$0
Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
</IfModule>
</FilesMatch>
you can have ajax request to a php file in your server and handle request to another domain using this php file.

Reportedly, as of VS 2013, this warning can be disabled. See the comment by @Mark Ransom.
Original Answer
You can't disable that specific warning.
According to Geoff Chappell the 4099 warning is treated as though it's too important to ignore, even by using in conjunction with /wx (which would treat warnings as errors and ignore the specified warning in other situations)
Here is the relevant text from the link:
Not Quite Unignorable Warnings
For some warning numbers, specification in a /ignore option is accepted but not necessarily acted upon. Should the warning occur while the /wx option is not active, then the warning message is still displayed, but if the /wx option is active, then the warning is ignored. It is as if the warning is thought important enough to override an attempt at ignoring it, but not if the user has put too high a price on unignored warnings.
The following warning numbers are affected:
4200, 4203, 4204, 4205, 4206, 4207, 4208, 4209, 4219, 4231 and 4237
Id like to say that instead of going with the systeminfo this would help over to get the total physical memory in GB's the machine
Get-CimInstance Win32_PhysicalMemory | Measure-Object -Property capacity -Sum | Foreach {"{0:N2}" -f ([math]::round(($_.Sum / 1GB),2))}
you can pass this value to the variable and get the gross output for the total physical memory in the machine
$totalmemory = Get-CimInstance Win32_PhysicalMemory | Measure-Object -Property capacity -Sum | Foreach {"{0:N2}" -f ([math]::round(($_.Sum / 1GB),2))}
$totalmemory
If you are uploading your files through GIT from your local machine then you can use the same command you are using in your local machine while you are connected to your live server using BASH or something like.You can use this as like you use locally.
php artisan cache:clear
php artisan route:cache
It should work.
I know this is a little late, but if someone else comes across this looking, you can now use public_path(); in Laravel 4, it has been added to the helper.php file in the support folder see here.
I had solved it on iPad. Try, if it works also on OSX.

Works only if you have content smaller then screen or you are using some layout framework (Angular Material in my case).
In Angular Material it is great, that you will disable over-scroll effect of whole page, but inner sections <md-content>
can be still scrollable.
just for modifying certain property from object collection you could directly use forEach with a collection as follows
collection.forEach(c -> c.setXyz(c.getXyz + "a"))
This is called string interpolation; it doesn't exist as such in Java.
One approach is to use String.format:
String string = String.format("A string %s", aVariable);
Another approach is to use a templating library such as Velocity or FreeMarker.
excel stores dates and times as a number representing the number of days since 1900-Jan-0, if you want to get the dates in date format using python, just subtract 2 days from the days column, as shown below:
Date = sheet.cell(1,0).value-2 //in python
at column 1 in my excel, i have my date and above command giving me date values minus 2 days, which is same as date present in my excel sheet
Try this:
$array = array_values($array);

Assuming that I
is your input image and F
is its Fourier Transform (i.e. F = fft2(I)
)
You can use this code:
F = fftshift(F); % Center FFT
F = abs(F); % Get the magnitude
F = log(F+1); % Use log, for perceptual scaling, and +1 since log(0) is undefined
F = mat2gray(F); % Use mat2gray to scale the image between 0 and 1
imshow(F,[]); % Display the result
mysqli is provided by php-mysql-5.3.3-40.el6_6.x86_64
You may need to try the following
yum install php-mysql-5.3.3-40.el6_6.x86_64
@bhamby is correct. By leaving the microseconds off of your timestamp value, your query would only match on a usagetime of 2012-09-03 08:03:06.000000
If you don't have the complete timestamp value captured from a previous query, you can specify a ranged predicate that will match on any microsecond value for that time:
...WHERE id = 1 AND usagetime BETWEEN '2012-09-03 08:03:06' AND '2012-09-03 08:03:07'
or
...WHERE id = 1 AND usagetime >= '2012-09-03 08:03:06'
AND usagetime < '2012-09-03 08:03:07'
If you are redirecting with PHP, then you would simply use the sleep() command to sleep for however many seconds before redirecting.
But, I think what you are referring to is the meta refresh tag:

If you want to use echo "a\tb"
in a script, you run the script as:
# sh -e myscript.sh
Alternatively, you can give to myscript.sh the execution permission, and then run the script.
# chmod +x myscript.sh
# ./myscript.sh
If you want to write percent (%), duplicate it:
<string name="percent">%1$d%%</string>
label.text = getString(R.string.percent, 75) // Output: 75%.
If you write simply %1$d%
, you will get the error: Format string 'percent' is not a valid format string so it should not be passed to String.format
.
You can also use the FileReader class :
var reader = new FileReader();
reader.onload = function (e) {
var data = this.result;
}
reader.readAsDataURL( file );
You can try this code for Swift
let popup : PopupVC = self.storyboard?.instantiateViewControllerWithIdentifier("PopupVC") as! PopupVC
let navigationController = UINavigationController(rootViewController: popup)
navigationController.modalPresentationStyle = UIModalPresentationStyle.OverCurrentContext
self.presentViewController(navigationController, animated: true, completion: nil)
For swift 4 latest syntax using extension
extension UIViewController {
func presentOnRoot(`with` viewController : UIViewController){
let navigationController = UINavigationController(rootViewController: viewController)
navigationController.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
self.present(navigationController, animated: false, completion: nil)
}
}
How to use
let popup : PopupVC = self.storyboard?.instantiateViewControllerWithIdentifier("PopupVC") as! PopupVC
self.presentOnRoot(with: popup)
Use the pandas idxmax
function. It's straightforward:
>>> import pandas
>>> import numpy as np
>>> df = pandas.DataFrame(np.random.randn(5,3),columns=['A','B','C'])
>>> df
A B C
0 1.232853 -1.979459 -0.573626
1 0.140767 0.394940 1.068890
2 0.742023 1.343977 -0.579745
3 2.125299 -0.649328 -0.211692
4 -0.187253 1.908618 -1.862934
>>> df['A'].argmax()
3
>>> df['B'].argmax()
4
>>> df['C'].argmax()
1
Alternatively you could also use numpy.argmax
, such as numpy.argmax(df['A'])
-- it provides the same thing, and appears at least as fast as idxmax
in cursory observations.
idxmax()
returns indices labels, not integers.
Index
you have to get it manually (which can be tricky now that duplicate row labels are allowed).HISTORICAL NOTES:
idxmax()
used to be called argmax()
prior to 0.11argmax
was deprecated prior to 1.0.0 and removed entirely in 1.0.0argmax
used to exist and perform the same function (though appeared to run more slowly than idxmax
).
argmax
function returned the integer position within the index of the row location of the maximum element.For example, consider this toy DataFrame
with a duplicate row label:
In [19]: dfrm
Out[19]:
A B C
a 0.143693 0.653810 0.586007
b 0.623582 0.312903 0.919076
c 0.165438 0.889809 0.000967
d 0.308245 0.787776 0.571195
e 0.870068 0.935626 0.606911
f 0.037602 0.855193 0.728495
g 0.605366 0.338105 0.696460
h 0.000000 0.090814 0.963927
i 0.688343 0.188468 0.352213
i 0.879000 0.105039 0.900260
In [20]: dfrm['A'].idxmax()
Out[20]: 'i'
In [21]: dfrm.iloc[dfrm['A'].idxmax()] # .ix instead of .iloc in older versions of pandas
Out[21]:
A B C
i 0.688343 0.188468 0.352213
i 0.879000 0.105039 0.900260
So here a naive use of idxmax
is not sufficient, whereas the old form of argmax
would correctly provide the positional location of the max row (in this case, position 9).
This is exactly one of those nasty kinds of bug-prone behaviors in dynamically typed languages that makes this sort of thing so unfortunate, and worth beating a dead horse over. If you are writing systems code and your system suddenly gets used on some data sets that are not cleaned properly before being joined, it's very easy to end up with duplicate row labels, especially string labels like a CUSIP or SEDOL identifier for financial assets. You can't easily use the type system to help you out, and you may not be able to enforce uniqueness on the index without running into unexpectedly missing data.
So you're left with hoping that your unit tests covered everything (they didn't, or more likely no one wrote any tests) -- otherwise (most likely) you're just left waiting to see if you happen to smack into this error at runtime, in which case you probably have to go drop many hours worth of work from the database you were outputting results to, bang your head against the wall in IPython trying to manually reproduce the problem, finally figuring out that it's because idxmax
can only report the label of the max row, and then being disappointed that no standard function automatically gets the positions of the max row for you, writing a buggy implementation yourself, editing the code, and praying you don't run into the problem again.
Abstraction is about identifying commonalities and reducing features that you have to work with at different levels of your code.
e.g. I may have a Vehicle
class. A Car
would derive from a Vehicle
, as would a Motorbike
. I can ask each Vehicle
for the number of wheels, passengers etc. and that info has been abstracted and identified as common from Cars
and Motorbikes
.
In my code I can often just deal with Vehicles
via common methods go()
, stop()
etc. When I add a new Vehicle type later (e.g. Scooter
) the majority of my code would remain oblivious to this fact, and the implementation of Scooter
alone worries about Scooter
particularities.
You are "tainting" the canvas by loading from a cross origins domain. Check out this MDN article:
https://developer.mozilla.org/en-US/docs/HTML/CORS_Enabled_Image
Since your 'value' also happens to match with ordinals you could just do:
public enum RelationActiveEnum {
Invited,
Active,
Suspended;
private final int value;
private RelationActiveEnum() {
this.value = ordinal();
}
}
And getting a enum from the value:
int value = 1;
RelationActiveEnum enumInstance = RelationActiveEnum.values()[value];
I guess an static method would be a good place to put this:
public enum RelationActiveEnum {
public static RelationActiveEnum fromValue(int value)
throws IllegalArgumentException {
try {
return RelationActiveEnum.values()[value]
} catch(ArrayIndexOutOfBoundsException e) {
throw new IllegalArgumentException("Unknown enum value :"+ value);
}
}
}
Obviously this all falls apart if your 'value' isn't the same value as the enum ordinal.
How about this. using the modulo operator
if(a%b==0)
{
System.out.println("b is a factor of a. i.e. the result of a/b is going to be an integer");
}
else
{
System.out.println("b is NOT a factor of a");
}

I had the same problem when i have trying to read xml that was extracted from archive to memory stream.
MemoryStream SubSetupStream = new MemoryStream();
using (ZipFile archive = ZipFile.Read(zipPath))
{
archive.Password = "SomePass";
foreach (ZipEntry file in archive)
{
file.Extract(SubSetupStream);
}
}
Problem was in these lines:
XmlDocument doc = new XmlDocument();
doc.Load(SubSetupStream);
And solution is (Thanks to @Phil):
if (SubSetupStream.Position>0)
{
SubSetupStream.Position = 0;
}
CSS transitions only animate from one set of styles to another; what you're looking for is CSS animations.
You need to define the animation keyframes and apply it to the element:
@keyframes changewidth {
from {
width: 100px;
}
to {
width: 300px;
}
}
div {
animation-duration: 0.1s;
animation-name: changewidth;
animation-iteration-count: infinite;
animation-direction: alternate;
}
Check out the link above to figure out how to customize it to your liking, and you'll have to add browser prefixes.
Convert Numpy to PIL
image and PIL to Numpy
import numpy as np

var elem = document.querySelector(".a.b");
Do you want to iterate over characters or words?
For words, you'll have to split the words first, such as
for index, word in enumerate(loopme.split(" ")):
print "CURRENT WORD IS", word, "AT INDEX", index
This prints the index of the word.
For the absolute character position you'd need something like
chars = 0
for index, word in enumerate(loopme.split(" ")):
print "CURRENT WORD IS", word, "AT INDEX", index, "AND AT CHARACTER", chars
chars += len(word) + 1
When reading sp_lock information, use the OBJECT_NAME( ) function to get the name of a table from its ID number, for example:
SELECT object_name(16003073)
EDIT :
There is another proc provided by microsoft which reports objects without the ID translation : http://support.microsoft.com/kb/q255596/
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.Transformation;
public class HeightAnimation extends Animation {
protected final int originalHeight;
protected final View view;
protected float perValue;
public HeightAnimation(View view, int fromHeight, int toHeight) {
this.view = view;
this.originalHeight = fromHeight;
this.perValue = (toHeight - fromHeight);
}
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
view.getLayoutParams().height = (int) (originalHeight + perValue * interpolatedTime);
view.requestLayout();
}
@Override
public boolean willChangeBounds() {
return true;
}
}
uss to:
HeightAnimation heightAnim = new HeightAnimation(view, view.getHeight(), viewPager.getHeight() - otherView.getHeight());
heightAnim.setDuration(1000);
view.startAnimation(heightAnim);
You should use below method-
Math.pow(double a, double b)
Returns the value of the first argument raised to the power of the second argument.
numba
module for speed up.On big datasets (500k >
) pd.cut
can be quite slow for binning data.
I wrote my own function in numba
with just in time compilation, which is roughly 16x
faster:
from numba import njit
@njit
def cut(arr):
bins = np.empty(arr.shape[0])
for idx, x in enumerate(arr):
if (x >= 0) & (x < 1):
bins[idx] = 1
elif (x >= 1) & (x < 5):
bins[idx] = 2
elif (x >= 5) & (x < 10):
bins[idx] = 3
elif (x >= 10) & (x < 25):
bins[idx] = 4
elif (x >= 25) & (x < 50):
bins[idx] = 5
elif (x >= 50) & (x < 100):
bins[idx] = 6
else:
bins[idx] = 7
return bins
cut(df['percentage'].to_numpy())
# array([5., 5., 7., 5.])
Optional: you can also map it to bins as strings:
a = cut(df['percentage'].to_numpy())
conversion_dict = {1: 'bin1',
2: 'bin2',
3: 'bin3',
4: 'bin4',
5: 'bin5',
6: 'bin6',
7: 'bin7'}
bins = list(map(conversion_dict.get, a))
# ['bin5', 'bin5', 'bin7', 'bin5']
Speed comparison:
# create dataframe of 8 million rows for testing
dfbig = pd.concat([df]*2000000, ignore_index=True)
dfbig.shape
# (8000000, 1)
%%timeit
cut(dfbig['percentage'].to_numpy())
# 38 ms ± 616 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
%%timeit
bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
pd.cut(dfbig['percentage'], bins=bins, labels=labels)
# 215 ms ± 9.76 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
I guess if you are using WSL with GUI, then you could just try
sudo /etc/init.d/docker start
Assuming that your profile in ~/aws/config
is using the region (instead of AZ as per your original question); the other cause is your client's inability to connect to s3.us-east-1.amazonaws.com
. In my case, I was unable to resolve that DNS name due to an error in my network configuration. Fixing the DNS issue solved my problem.
A simple change in Num2 class like this:
super().__init__(num)
It works in python3.
class Num:
def __init__(self,num):
self.n1 = num
class Num2(Num):
def __init__(self,num):
super().__init__(num)
self.n2 = num*2
def show(self):
print (self.n1,self.n2)
mynumber = Num2(8)
mynumber.show()
There are also new kids on the block!
If you need a more in-depth comparison please read this and you may end up using docopt or click. Thanks to Kyle Purdon!
I just ran into this issue while working with Eclipse. In my case, I had the correct Hadoop version downloaded (hadoop-2.5.0-cdh5.3.0.tgz), I extracted the contents and placed it directly in my C drive. Then I went to
Eclipse->Debug/Run Configurations -> Environment (tab) -> and added
variable: HADOOP_HOME
Value: C:\hadoop-2.5.0-cdh5.3.0
If you are trying to exclude Version Control System (VCS) files, tar already supports two interesting options about it! :)
This option excludes files and directories used by following version control systems: CVS
, RCS
, SCCS
, SVN
, Arch
, Bazaar
, Mercurial
, and Darcs
.
As of version 1.32, the following files are excluded:
CVS/
, and everything under itRCS/
, and everything under itSCCS/
, and everything under it.git/
, and everything under it.gitignore
.gitmodules
.gitattributes
.cvsignore
.svn/
, and everything under it.arch-ids/
, and everything under it{arch}/
, and everything under it=RELEASE-ID
=meta-update
=update
.bzr
.bzrignore
.bzrtags
.hg
.hgignore
.hgrags
_darcs
When archiving directories that are under some version control system (VCS), it is often convenient to read exclusion patterns from this VCS' ignore files (e.g. .cvsignore
, .gitignore
, etc.) This option provide such possibility.
Before archiving a directory, see if it contains any of the following files: cvsignore
, .gitignore
, .bzrignore
, or .hgignore
. If so, read ignore patterns from these files.
The patterns are treated much as the corresponding VCS would treat them, i.e.:
.cvsignore
Contains shell-style globbing patterns that apply only to the directory where this file resides. No comments are allowed in the file. Empty lines are ignored.
.gitignore
Contains shell-style globbing patterns. Applies to the directory where .gitfile
is located and all its subdirectories.
Any line beginning with a #
is a comment. Backslash escapes the comment character.
.bzrignore
Contains shell globbing-patterns and regular expressions (if prefixed with RE:
(16). Patterns affect the directory and all its subdirectories.
Any line beginning with a #
is a comment.
.hgignore
Contains posix regular expressions(17). The line syntax: glob
switches to shell globbing patterns. The line syntax: regexp
switches back. Comments begin with a #
. Patterns affect the directory and all its subdirectories.
tar -czv --exclude-vcs --exclude-vcs-ignores -f path/to/my-tar-file.tar.gz path/to/my/project/
The numpy.savetxt()
method has several parameters which are worth noting:
fmt : str or sequence of strs, optional
it is used to format the numbers in the array, see the doc for details on formatingdelimiter : str, optional
String or character separating columnsnewline : str, optional
String or character separating lines.
Let's take an example. I have an array of size (M, N)
, which consists of integer numbers in the range (0, 255). To save the array row-wise and show it nicely, we can use the following code:
import numpy as np
np.savetxt("my_array.txt", my_array, fmt="%4d", delimiter=",", newline="\n")
I had a similar issue. I resolved it by changing
<basicHttpBinding>
to
<basicHttpsBinding>
and also changed my URL to use https:// instead of http://.
Also in <endpoint> node, change
binding="basicHttpBinding"
to
binding="basicHttpsBinding"
This worked.

I changed 3 things and then it works:
If your index is less than the size of your list then it does exist, possibly with null
value. If index is bigger then you may call ensureCapacity()
to be able to use that index.
If you want to check if a value at your index is null
or not, call get()
This is another example of how to use keySet(), get(), values() and entrySet() functions to obtain Keys and Values in a Map:
Map<Integer, String> testKeyset = new HashMap<Integer, String>();
testKeyset.put(1, "first");
testKeyset.put(2, "second");
testKeyset.put(3, "third");
testKeyset.put(4, "fourth");
// Print a single value relevant to a specified Key. (uses keySet())
for(int mapKey: testKeyset.keySet())
System.out.println(testKeyset.get(mapKey));
// Print all values regardless of the key.
for(String mapVal: testKeyset.values())
System.out.println(mapVal.trim());
// Displays the Map in Key-Value pairs (e.g: [1=first, 2=second, 3=third, 4=fourth])
System.out.println(testKeyset.entrySet());

I normally set paths in
~/.bashrc
However for Java, I followed instructions at https://askubuntu.com/questions/55848/how-do-i-install-oracle-java-jdk-7
and it was sufficient for me.
you can also define multiple java_home's and have only one of them active (rest commented).
suppose in your bashrc file, you have
export JAVA_HOME=......jdk1.7
#export JAVA_HOME=......jdk1.8
notice 1.8 is commented. Once you do
source ~/.bashrc
jdk1.7 will be in path.
you can switch them fairly easily this way. There are other more permanent solutions too. The link I posted has that info.

In JavaScript, primitive types such as integers and strings are passed by value whereas objects are passed by reference. So in order to achieve this you need to use an object:
// declare an object with property x
var obj = { x: 1 };
var aliasToObj = obj;
aliasToObj.x ++;
alert( obj.x ); // displays 2
select t.name as TriggerName,m.definition,is_disabled
from sys.all_sql_modules m
inner join
sys.triggers t
on m.object_id = t.object_id
inner join sys.objects o
on o.object_id = t.parent_id
Where o.name = 'YourTableName'
This will give you all triggers on a Specified Table

You've tagged this SQL Server 2008 but future visitors to this question (using SQL Server 2016+) will likely want to know about STRING_SPLIT
.
With this new builtin function you can now just use
SELECT TRY_CAST(value AS INT)
FROM STRING_SPLIT ('1,2,3,4,5,6,7,8,9,10,11,12,13,14,15', ',')
Some restrictions of this function and some promising results of performance testing are in this blog post by Aaron Bertrand.
There is a big difference. Tasks are scheduled on the ThreadPool and could even be executed synchronous if appropiate.
If you have a long running background work you should specify this by using the correct Task Option.
You should prefer Task Parallel Library over explicit thread handling, as it is more optimized. Also you have more features like Continuation.
If you want to make sure that last row does not wrap and thus size the way you want it, have a look at
td {
white-space: nowrap;
}
You are just updating the value of i
in the loop. The value of i
should also be added each time.
It is never a good idea to update the value of i
inside the for
loop. The for
loop index should only be used as a counter. In your case, changing the value of i
inside the loop will cause all sorts of confusion.
Create variable total
that holds the sum of the numbers up to i
.
So
for (int i = 0; i < positiveInteger; i++)
total += i;
Check out this awesome converter. http://labs.rampinteractive.co.uk/android_dp_px_calculator/
As I understand, you want the average value for each id at each pass. The solution is
SELECT id, pass, avg(value) FROM data_r1
GROUP BY id, pass;
Encountered a similar problem today. Did not see my fix listed here, so I thought I'd share.
Root could not erase a file.
I did my research. Turns out there's something called an immutable bit.
# lsattr /path/file
----i-------- /path/file
#
This bit being configured prevents even root from modifying/removing it.
To remove this I did:
# chattr -i /path/file
After that I could rm the file.
In reverse, it's a neat trick to know if you have something you want to keep from being gone.

If you call daemon() and then daemonize a process, by default the current working directory will change to /
. So if your program is a daemon then you should be looking for a core in /
directory and not in the directory of the binary.
the key point is finding the right path where your grunt was installed.
I installed grunt through npm, but my grunt path was /Users/${whoyouare}/.npm-global/lib/node_modules/grunt/bin/grunt
. So after I added /Users/${whoyouare}/.npm-global/lib/node_modules/grunt/bin
to ~/.bash_profile
,and source ~/.bash_profile
, It worked.
So the steps are as followings:
1. find the path where your grunt was installed(when you installed grunt, it told you. if you don't remember, you can install it one more time)
2. vi ~/.bash_profile
3. export PATH=$PATH:/your/path/where/grunt/was/installed
4. source ~/.bash_profile

<span> normal text</span> <spanspan>

Here's an interesting benchmark http://zi.fi/shootout/
If those are actually fields of a certain class, then you can get them with a little help of reflection:
package test;
import java.lang.reflect.Field;
import java.lang.reflect.ParameterizedType;
import java.util.ArrayList;
import java.util.List;
public class Test {
List<String> stringList = new ArrayList<String>();
List<Integer> integerList = new ArrayList<Integer>();
public static void main(String... args) throws Exception {
Field stringListField = Test.class.getDeclaredField("stringList");
ParameterizedType stringListType = (ParameterizedType) stringListField.getGenericType();
Class<?> stringListClass = (Class<?>) stringListType.getActualTypeArguments()[0];
System.out.println(stringListClass); // class java.lang.String.
Field integerListField = Test.class.getDeclaredField("integerList");
ParameterizedType integerListType = (ParameterizedType) integerListField.getGenericType();
Class<?> integerListClass = (Class<?>) integerListType.getActualTypeArguments()[0];
System.out.println(integerListClass); // class java.lang.Integer.
}
}
You can also do that for parameter types and return type of methods.
But if they're inside the same scope of the class/method where you need to know about them, then there's no point of knowing them, because you already have declared them yourself.
Don't render 404 yourself, there's no reason to; Rails has this functionality built in already. If you want to show a 404 page, create a render_404
method (or not_found
as I called it) in ApplicationController
like this:
def not_found
raise ActionController::RoutingError.new('Not Found')
end
Rails also handles AbstractController::ActionNotFound
, and ActiveRecord::RecordNotFound
the same way.
This does two things better:
1) It uses Rails' built in rescue_from
handler to render the 404 page, and
2) it interrupts the execution of your code, letting you do nice things like:
user = User.find_by_email(params[:email]) or not_found
user.do_something!
without having to write ugly conditional statements.
As a bonus, it's also super easy to handle in tests. For example, in an rspec integration test:
# RSpec 1
lambda {
visit '/something/you/want/to/404'
}.should raise_error(ActionController::RoutingError)
# RSpec 2+
expect {
get '/something/you/want/to/404'
}.to raise_error(ActionController::RoutingError)
And minitest:
assert_raises(ActionController::RoutingError) do
get '/something/you/want/to/404'
end
OR refer more info from Rails render 404 not found from a controller action
In C and C++ memory requirements of some variable :

int: -2^31 to +2^31-1
long: -2^31 to +2^31-1
long long: -2^63 to +2^63-1
depends on compiler and architecture of hardware
The international standard for the C language requires only that the size of short variables should be less than or equal to the size of type int, which in turn should be less than or equal to the size of type long.
In my case, it was caused by a missing (0)

in an anchor.
This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.
var fs = require("fs");
var filename = "./index.html";
function start(resp) {
fs.readFile(filename, "utf8", function(err, data) {
if (err) {
// may be filename does not exists?
resp.writeHead(404, {
'Content-Type' : 'text/html'
});
// log this error into browser
resp.write(err.toString());
resp.end();
} else {
resp.writeHead(200, {
"Content-Type": "text/html"
});
resp.write(data.toString());
resp.end();
}
});
}

'UTC'
) or as an interval (e.g., INTERVAL '-08:00'
) - here is a list of all available time zonesnow()
returns a value of type timestamp (just what we need) with your database's default time zone attached (e.g. 2018-11-11T12:07:22.3+05:00
).timezone('UTC', now())
turns our current time (of type timestamp with time zone) into the timezonless equivalent in UTC
.SELECT timestamp with time zone '2020-03-16 15:00:00-05' AT TIME ZONE 'UTC'
will return 2020-03-16T20:00:00Z

You can connect to psql as below and write your sql queries like you do in a regular postgres function within the block. There, bash variables can be used. However, the script should be strictly sql, even for comments you need to use -- instead of #:
#!/bin/bash
psql postgresql://<user>:<password>@<host>/<db> << EOF
<your sql queries go here>
EOF
div { margin: auto; }
This will center your div.
Div by itself is a blockelement. Therefor you need to define the style to the div how to behave.
Here it goes an example:
$.post("test.php", { 'choices[]': ["Jon", "Susan"] });
Hope it helps.
There are two solutions to this:
a) Set your PATH variable to include "/usr/local/bin"
export PATH="$PATH:/usr/local/bin"
b) Create a symlink to "/usr/bin" which is already in your PATH
ln -s /usr/bin/nodejs /usr/bin/node
I hope it helps.

var txt = "";
var i;
for (i = 0; i < x.length; i++) {
if (x[i].name=="video")
{
alert(x[i].content);
}
}

That's the correct way. Calendars work the same way. The best I could offer you (based on your example) is this:
boolean isWithinRange(Date testDate) {
return testDate.getTime() >= startDate.getTime() &&
testDate.getTime() <= endDate.getTime();
}
Date.getTime() returns the number of milliseconds since 1/1/1970 00:00:00 GMT, and is a long so it's easily comparable.
The correct way to do this is:
String[] stockArr = stock_list.toArray(new String[stock_list.size()]);
I'd like to add to the other great answers here and explain how you could have used the Javadocs to answer your question.
The Javadoc for toArray()
(no arguments) is here. As you can see, this method returns an Object[]
and not String[]
which is an array of the runtime type of your list:
public Object[] toArray()
Returns an array containing all of the elements in this collection. If the collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order. The returned array will be "safe" in that no references to it are maintained by the collection. (In other words, this method must allocate a new array even if the collection is backed by an Array). The caller is thus free to modify the returned array.
Right below that method, though, is the Javadoc for toArray(T[] a)
. As you can see, this method returns a T[]
where T
is the type of the array you pass in. At first this seems like what you're looking for, but it's unclear exactly why you're passing in an array (are you adding to it, using it for just the type, etc). The documentation makes it clear that the purpose of the passed array is essentially to define the type of array to return (which is exactly your use case):
public <T> T[] toArray(T[] a)
Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array. If the collection fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this collection. If the collection fits in the specified array with room to spare (i.e., the array has more elements than the collection), the element in the array immediately following the end of the collection is set to null. This is useful in determining the length of the collection only if the caller knows that the collection does not contain any null elements.)
If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.
This implementation checks if the array is large enough to contain the collection; if not, it allocates a new array of the correct size and type (using reflection). Then, it iterates over the collection, storing each object reference in the next consecutive element of the array, starting with element 0. If the array is larger than the collection, a null is stored in the first location after the end of the collection.
Of course, an understanding of generics (as described in the other answers) is required to really understand the difference between these two methods. Nevertheless, if you first go to the Javadocs, you will usually find your answer and then see for yourself what else you need to learn (if you really do).
Also note that reading the Javadocs here helps you to understand what the structure of the array you pass in should be. Though it may not really practically matter, you should not pass in an empty array like this:
String [] stockArr = stockList.toArray(new String[0]);
Because, from the doc, this implementation checks if the array is large enough to contain the collection; if not, it allocates a new array of the correct size and type (using reflection). There's no need for the extra overhead in creating a new array when you could easily pass in the size.
As is usually the case, the Javadocs provide you with a wealth of information and direction.

Databases all the way.
However, if you still have a need for storing files, don't have the capacity to take on a new RDBMS (like Oracle, SQLServer, etc), than look into XML.
XML is a structure file format which offers you the ability to store things as a file but give you query power over the file and data within it. XML Files are easier to read than flat files and can be easily transformed applying an XSLT for even better human-readability. XML is also a great way to transport data around if you must.
I strongly suggest a DB, but if you can't go that route, XML is an ok second.

Printing the exception's stack trace in itself doesn't constitute bad practice, but only printing the stace trace when an exception occurs is probably the issue here -- often times, just printing a stack trace is not enough.
Also, there's a tendency to suspect that proper exception handling is not being performed if all that is being performed in a catch
block is a e.printStackTrace
. Improper handling could mean at best an problem is being ignored, and at worst a program that continues executing in an undefined or unexpected state.
Example
Let's consider the following example:
try {
initializeState();
} catch (TheSkyIsFallingEndOfTheWorldException e) {
e.printStackTrace();
}
continueProcessingAssumingThatTheStateIsCorrect();
Here, we want to do some initialization processing before we continue on to some processing that requires that the initialization had taken place.
In the above code, the exception should have been caught and properly handled to prevent the program from proceeding to the continueProcessingAssumingThatTheStateIsCorrect
method which we could assume would cause problems.
In many instances, e.printStackTrace()
is an indication that some exception is being swallowed and processing is allowed to proceed as if no problem every occurred.
Why has this become a problem?
Probably one of the biggest reason that poor exception handling has become more prevalent is due to how IDEs such as Eclipse will auto-generate code that will perform a e.printStackTrace
for the exception handling:
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
(The above is an actual try-catch
auto-generated by Eclipse to handle an InterruptedException
thrown by Thread.sleep
.)
For most applications, just printing the stack trace to standard error is probably not going to be sufficient. Improper exception handling could in many instances lead to an application running in a state that is unexpected and could be leading to unexpected and undefined behavior.
If you use sizeof()
then a char *str
and char str[]
will return different answers. char str[]
will return the length of the string(including the string terminator) while char *str
will return the size of the pointer(differs as per compiler).
That error is due to missing of modules in pyinstaller. You can find the missing modules by running script in executable command line, i.e., by removing '-w' from the command. Once you created the command line executable file then in command line it will show the missing modules. By finding those missing modules you can add this to your command : " --hidden-import = missingmodule "

Problem Cause
In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There are Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.
Solution
~/.matplotlib
. ~/.matplotlib/matplotlibrc
there and add the following code: backend: TkAgg
From this link you can try different diagrams.
Use the observer pattern. It works like this:
interface MyListener{
void somethingHappened();
}
public class MyForm implements MyListener{
MyClass myClass;
public MyForm(){
this.myClass = new MyClass();
myClass.addListener(this);
}
public void somethingHappened(){
System.out.println("Called me!");
}
}
public class MyClass{
private List<MyListener> listeners = new ArrayList<MyListener>();
public void addListener(MyListener listener) {
listeners.add(listener);
}
void notifySomethingHappened(){
for(MyListener listener : listeners){
listener.somethingHappened();
}
}
}
You create an interface which has one or more methods to be called when some event happens. Then, any class which needs to be notified when events occur implements this interface.
This allows more flexibility, as the producer is only aware of the listener interface, not a particular implementation of the listener interface.
In my example:
MyClass
is the producer here as its notifying a list of listeners.
MyListener
is the interface.
MyForm
is interested in when somethingHappened
, so it is implementing MyListener
and registering itself with MyClass
. Now MyClass
can inform MyForm
about events without directly referencing MyForm
. This is the strength of the observer pattern, it reduces dependency and increases reusability.
visibility
property makes the element visible or invisible.
function showTable(){
document.getElementById('table').style.visibility = "visible";
}
function hideTable(){
document.getElementById('table').style.visibility = "hidden";
}
You must write
<img src="theSource" style="width:30px;height:30px;" />
Inline styling will always take precedence over CSS styling. The width and height attributes are being overridden by your stylesheet, so you need to switch to this format.
Did you try with setTransformationMethod? It's inherited from TextView and want a TransformationMethod as a parameter.

Make sure the client computer has the same or higher version of the .NET framework that you built your program to.
You can still use angular.isDefined()
You just need to set

It depends on the host, but you probably simply can't (you can't on my shared host on Rackspace Cloud Sites - I asked them).
What you can do is set up an environment on your dev machine that roughly matches your shared host, and do all of your management through the command line locally. Then when everything is set (you've pulled in all the dependencies, updated, managed with git, etc.) you can "push" that to your shared host over (s)FTP.
There is a method not described in the answers but described in the documentation for the numpy.ndarray.transpose
method:
For a 1-D array this has no effect, as a transposed vector is simply the same vector. To convert a 1-D array into a 2D column vector, an additional dimension must be added. np.atleast2d(a).T achieves this, as does a[:, np.newaxis].
One can do:
import numpy as np
a = np.array([5,4])
print(a)
print(np.atleast_2d(a).T)
Which (imo) is nicer than using newaxis
.
This also can happen if the device you are trying to run on has some older version of the provisioning profile you are using that points to an old, expired or revoked certificate or a certificate without associated private key. Delete any invalid Provisioning Profiles under your device section in Xcode organizer.
I think a solution is to put count in back ticks
.filter("`count` >= 2")
Took a lot of googling but here is what I do in Python for MySql when I want to delete multiple items from a single table using a list of values.
#create some empty list
values = []
#continue to append the values you want to delete to it
#BUT you must ensure instead of a string it's a single value tuple
values.append(([Your Variable],))
#Then once your array is loaded perform an execute many
cursor.executemany("DELETE FROM YourTable WHERE ID = %s", values)
I just had this issue in my duplicated project and solved by checking 2 places:
1- Make sure you have the .m file in the list -> Project - Build Phases - Compile Sources
2- After that, go to interface builder (probably this is an error occures with only IB) and unlink all properties, labels, images, etc... Then re-link all. I have realized that I've removed an attribute but it was still linked in IB.
Hope it works for some.
I needed to copy all .md files from one directory into another, so here is what I did.
for i in **/*.md;do mkdir -p ../docs/"$i" && rm -r ../docs/"$i" && cp "$i" "../docs/$i" && echo "$i -> ../docs/$i"; done
Which is pretty hard to read, so lets break it down.
first cd into the directory with your files,
for i in **/*.md;
for each file in your pattern
mkdir -p ../docs/"$i"
make that directory in a docs folder outside of folder containing your files. Which creates an extra folder with the same name as that file.
rm -r ../docs/"$i"
remove the extra folder that is created as a result of mkdir -p
cp "$i" "../docs/$i"
Copy the actual file
echo "$i -> ../docs/$i"
Echo what you did
; done
Live happily ever after
You don't really need all that much code:
IFS=$'\n' sorted=($(sort <<<"${array[*]}"))
unset IFS
Supports whitespace in elements (as long as it's not a newline), and works in Bash 3.x.
e.g.:
$ array=("a c" b f "3 5")
$ IFS=$'\n' sorted=($(sort <<<"${array[*]}")); unset IFS
$ printf "[%s]\n" "${sorted[@]}"
[3 5]
[a c]
[b]
[f]
Note: @sorontar has pointed out that care is required if elements contain wildcards such as *
or ?
:
The sorted=($(...)) part is using the "split and glob" operator. You should turn glob off:
set -f
orset -o noglob
orshopt -op noglob
or an element of the array like*
will be expanded to a list of files.
The result is a culmination six things that happen in this order:
IFS=$'\n'
"${array[*]}"
<<<
sort
sorted=($(...))
unset IFS
IFS=$'\n'
This is an important part of our operation that affects the outcome of 2 and 5 in the following way:
Given:
"${array[*]}"
expands to every element delimited by the first character of IFS
sorted=()
creates elements by splitting on every character of IFS
IFS=$'\n'
sets things up so that elements are expanded using a new line as the delimiter, and then later created in a way that each line becomes an element. (i.e. Splitting on a new line.)
Delimiting by a new line is important because that's how sort
operates (sorting per line). Splitting by only a new line is not-as-important, but is needed preserve elements that contain spaces or tabs.
The default value of IFS
is a space, a tab, followed by a new line, and would be unfit for our operation.
sort <<<"${array[*]}"
part<<<
, called here strings, takes the expansion of "${array[*]}"
, as explained above, and feeds it into the standard input of sort
.
With our example, sort
is fed this following string:
a c
b
f
3 5
Since sort
sorts, it produces:
3 5
a c
b
f
sorted=($(...))
partThe $(...)
part, called command substitution, causes its content (sort <<<"${array[*]}
) to run as a normal command, while taking the resulting standard output as the literal that goes where ever $(...)
was.
In our example, this produces something similar to simply writing:
sorted=(3 5
a c
b
f
)
sorted
then becomes an array that's created by splitting this literal on every new line.
unset IFS
This resets the value of IFS
to the default value, and is just good practice.
It's to ensure we don't cause trouble with anything that relies on IFS
later in our script. (Otherwise we'd need to remember that we've switched things around--something that might be impractical for complex scripts.)
This is question was posted like ages back, but today when i was looking for the same answer "How to detect zoom in and out event", i couldn't find one answer that would fit all the browsers.
As on now : For Firefox/Chrome/IE8 and IE9 , the zoom in and out fires a window.resize event. This can be captured using:
$(window).resize(function() {
//YOUR CODE.
});
To prevent your code from crashes, you maybe want to use a try-except
to catch TypeErrors
>>> ord("¶")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: ord() expected a character, but string of length 2 found
For example
def is_ascii(s):
try:
return all(ord(c) < 128 for c in s)
except TypeError:
return False
For relative imports see the documentation. A relative import is when you import from a module relative to that module's location, instead of absolutely from sys.path
.
As for import *
, Python 2 allowed star imports within functions, for instance:
>>> def f():
... from math import *
... print sqrt
A warning is issued for this in Python 2 (at least recent versions). In Python 3 it is no longer allowed and you can only do star imports at the top level of a module (not inside functions or classes).
Make sure you have the right selector, and then wait until the page is ready and that the element exists until you run the function.
$(function(){
$('#searchBar').val('hi')
});
As Derek points out, the ID is wrong as well.
Change to $('#main_search')
What's wrong with this?
foo.replace(" ", "")[:-3].upper()
You just need this:
$(".hidden").attr("placeholder", "Type here to search");
classList
is used for manipulating classes and not attributes.
this type of error usually occur when you try to access data through the index in which data data has not been assign. for example
//assign of data in to array
for(int i=0; i<10; i++){
arr[i]=i;
}
//accessing of data through array index
for(int i=10; i>=0; i--){
cout << arr[i];
}
the code will give error (vector subscript out of range) because you are accessing the arr[10] which has not been assign yet.
To use GPU from docker container, instead of using native Docker, use Nvidia-docker. To install Nvidia docker use following commands
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
curl -s -L https://nvidia.github.io/nvidia-docker/ubuntu16.04/amd64/nvidia-
docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt-get update
sudo apt-get install -y nvidia-docker
sudo pkill -SIGHUP dockerd # Restart Docker Engine
sudo nvidia-docker run --rm nvidia/cuda nvidia-smi # finally run nvidia-smi in the same container
None of these will allow you to compile PHP with cURL enabled.
In order to compile with cURL, you need libcurl header files (.h files). They are usually found in /usr/include/curl
. They generally are bundled in a separate development package.
Per example, to install libcurl in Ubuntu:
sudo apt-get install libcurl4-gnutls-dev
Or CentOS:
sudo yum install curl-devel
Then you can just do:
./configure --with-curl # other options...
If you compile cURL manually, you can specify the path to the files without the lib
or include
suffix. (e.g.: /usr/local
if cURL headers are in /usr/local/include/curl
).
**multiple delete not working**
function delete_selection()
{
$id_array = array();
$selection = $this->input->post("selection", TRUE);
$id_array = explode("|", $selection);
foreach ($id_array as $item):
if ($item != ''):
//DELETE ROW
$this->db->where('entry_id', $item);
$this->db->delete('helpline_entry');
endif;
endforeach;
}
It almost never makes intuitive sense to have two inputs next to each other without labels. Here is a solution with labels mixed in, which also works quite well with just a minor modification to existing Bootstrap styles.
Preview:
HTML:
<div class="input-group">
<span class="input-group-addon">Between</span>
<input type="text" class="form-control" placeholder="Type something..." />
<span class="input-group-addon" style="border-left: 0; border-right: 0;">and</span>
<input type="text" class="form-control" placeholder="Type something..." />
</div>
CSS:
.input-group-addon {
border-left-width: 0;
border-right-width: 0;
}
.input-group-addon:first-child {
border-left-width: 1px;
}
.input-group-addon:last-child {
border-right-width: 1px;
}

On the other hand mongoose
as an ORM (Object Relational Mapping) can be a better choice for the new-bies.
Had the same issue and what worked for me was:
Checking the ownership of /var/run/docker.sock
ls -l /var/run/docker.sock
If you're not the owner then change ownership with the command
sudo chown *your-username* /var/run/docker.sock
Then you can go ahead and try executing the docker commands hassle-free :D
In our experience, with Apache falling over on request of favicon.ico, we commented out extra headers in the .htaccess file.
For example we had Header set X-XSS-Protection "1; mode=block"
... but we had forgotten to sudo a2enmod headers beforehand. Commenting out extra headers being sent resolved our favicon.ico issue.
We also had several virtual hosts set up for development, and only failed out with 500 Internal Server Error when using http://localhost and fetching /favicon.ico. If you run "curl -v http://localhost/favicon.ico" and get a warning about the host name not being in the resolver cache or something to that effect, you might experience problems.
It could be as simple as not fetching (we tried that and it didn't work, because our root cause was different) or look around for directives in apache2.conf or .htaccess which might be causing strange 500 Internal Server Error messages.
We found it failed so quickly there was nothing useful in Apache's error logs whatsoever and spent an entire morning changing small things here and there until we resolved the problem of setting extra headers when we had forgotten to have mod_headers loaded!
Thanks HansUp for your answer, it is very helpful and it works!
I found three patterns working in Access, yours is the best, because it works in all cases.
INNER JOIN, your variant. I will call it "closed set pattern". It is possible to join more than two tables to the same table with good performance only with this pattern.
SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
FROM
((class
INNER JOIN person AS cr
ON class.C_P_ClassRep=cr.P_Nr
)
INNER JOIN person AS cr2
ON class.C_P_ClassRep2nd=cr2.P_Nr
)
;
INNER JOIN "chained-set pattern"
SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
FROM person AS cr
INNER JOIN ( class
INNER JOIN ( person AS cr2
) ON class.C_P_ClassRep2nd=cr2.P_Nr
) ON class.C_P_ClassRep=cr.P_Nr
;
CROSS JOIN with WHERE
SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
FROM class, person AS cr, person AS cr2
WHERE class.C_P_ClassRep=cr.P_Nr AND class.C_P_ClassRep2nd=cr2.P_Nr
;
In my case bind_ip was not 127.0.0.1 in /etc/mongodb.conf file so change bind_ip to 127.0.0.1(it may be comma separated values so make sure 127.0.0.1 is one of them) Then restart your system to take effect. Restart only to the those who are facing

This should be performant, thread-safe and flexible enough for many uses:
#include <random>
#include <iostream>
template<typename Numeric, typename Generator = std::mt19937>
Numeric random(Numeric from, Numeric to)
{
thread_local static Generator gen(std::random_device{}());
using dist_type = typename std::conditional
<
std::is_integral<Numeric>::value
, std::uniform_int_distribution<Numeric>
, std::uniform_real_distribution<Numeric>
>::type;
thread_local static dist_type dist;
return dist(gen, typename dist_type::param_type{from, to});
}
int main(int, char*[])
{
for(auto i = 0U; i < 20; ++i)
std::cout << random<double>(0.0, 0.3) << '\n';
}
Relative paths are relative to current working directory. If you do not your want your path to be, it must be absolute.
But there is an often used trick to build an absolute path from current script: use its __file__
special attribute:
from pathlib import Path
path = Path(__file__).parent / "../data/test.csv"
with path.open() as f:
test = list(csv.reader(f))
This requires python 3.4+ (for the pathlib module).
If you still need to support older versions, you can get the same result with:
import csv
import os.path
my_path = os.path.abspath(os.path.dirname(__file__))
path = os.path.join(my_path, "../data/test.csv")
with open(path) as f:
test = list(csv.reader(f))
[2020 edit: python3.4+ should now be the norm, so I moved the pathlib version inspired by jpyams' comment first]
Not an answer, but just some suggestions.
Select a more suitable FS (file system). Since from a historic point of view, all your issues were wise enough, to be once central to FSs evolving over decades. I mean more modern FS better support your issues. First make a comparison decision table based on your ultimate purpose from FS list.
I think its time to shift your paradigms. So I personally suggest using a distributed system aware FS, which means no limits at all regarding size, number of files and etc. Otherwise you will sooner or later challenged by new unanticipated problems.
I'm not sure to work, but if you don't mention some experimentation, give AUFS over your current file system a try. I guess it has facilities to mimic multiple folders as a single virtual folder.
To overcome hardware limits you can use RAID-0.
In c# following code insert data into datatable on specified position
DataTable dt = new DataTable();
dt.Columns.Add("SL");

dt.Rows.InsertAt(dt.NewRow(), 3);
var rowPosition = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("SL")] = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("Amount")] = 3000;

Admittedly, it is more Pythonic than of the PHP idiom, but on the other hand, you don't have to worry about dealing with a copious amount of extra data.
So, this answer has been marked down at least twice as of the time I am writing this message. Assuming that I had made some gargantuan error, I went and I ran some benchmarks, and this is what I found that my solution is over 10% faster than the nearest alternative when the table does not exist, and it over 25% faster when the table does exist:
:::::::::::::::::::::::::BEGINNING NON-EXISTING TABLE::::::::::::::::::::::::::::::
23.35501408577 for bad select
25.408507823944 for select from schema num rows -- calls mysql_num_rows on select... from information_schema.
25.336688995361 for select from schema fetch row -- calls mysql_fetch_row on select... from information_schema result
50.669058799744 for SHOW TABLES FROM test
:::::::::::::::::::::::::BEGINNING EXISTING TABLE::::::::::::::::::::::::::::::
15.293519973755 for good select
20.784908056259 for select from schema num rows
21.038464069366 for select from schema fetch row
50.400309085846 for SHOW TABLES FROM test
I tried running this against DESC, but I had a timeout after 276 seconds (24 seconds for my answer, 276 to fail to complete the description of a non existing table).
For good measure, I am benchmarking against a schema with only four tables in it and this is an almost fresh MySQL install (this is the only database so far). To see the export, look here.
This particular solution is also more database independent as the same query will work in PgSQL and Oracle.
mysql_query()
returns FALSE for errors that aren't "this table doesn't exist".
If you need to guarantee that the table doesn't exist, use mysql_errno()
to get the error code and compare it to the relevant MySQL errors.
In my case I used another solution.
As the project doesn't require CommonJS and it must have ES3 compatibility (modules not supported) all you need is just remove all export and import statements from your code, because your tsconfig doesn't contain
"module": "commonjs"
But use import and export statements in your referenced files
import { Utils } from "./utils"
export interface Actions {}
Final generated code will always have(at least for TypeScript 3.0) such lines
"use strict";
exports.__esModule = true;
var utils_1 = require("./utils");
....
utils_1.Utils.doSomething();
Here's an example to help you out ...
fig = plt.figure(figsize=(10,5))
ax = fig.add_subplot(111)
ax.set_title('ADR vs Rating (CS:GO)')
ax.scatter(x=data[:,0],y=data[:,1],label='Data')
plt.plot(data[:,0], m*data[:,0] + b,color='red',label='Our Fitting
Line')
ax.set_xlabel('ADR')
ax.set_ylabel('Rating')
ax.legend(loc='best')
plt.show()
no. You can use UDF in which you can pass parameters.
Check out Datejs. Their built in formatters can do this: http://code.google.com/p/datejs/wiki/APIDocumentation#toString
It's a really handy library, especially if you are planning on doing other things with date objects.
You have to indent the docstring after the function definition there (line 3, 4):
def print_lol(the_list):
"""this doesn't works"""
print 'Ain't happening'
Indented:
def print_lol(the_list):
"""this works!"""
print 'Aaaand it's happening'
Or you can use #
to comment instead:
def print_lol(the_list):
#this works, too!
print 'Hohoho'
Also, you can see PEP 257 about docstrings.
Hope this helps!
The problem is that your controller expect a parameter hasId=false or hasId=true, but you are not passing that. Your hidden field has the id hasId but is passed as hasCustomerName, so no mapping matches.
Either change the path of the hidden field to hasId or the mapping parameter to expect hasCustomerName=true or hasCustomerName=false.
Starting from API level 5 you can call overridePendingTransition immediately to specify an explicit transition animation:
startActivity();
overridePendingTransition(R.anim.hold, R.anim.fade_in);
or
finish();
overridePendingTransition(R.anim.hold, R.anim.fade_out);
You could use read.table
with an empty string for the input text
as follows:
colClasses = c("Date", "character", "character")
col.names = c("Date", "File", "User")
df <- read.table(text = "",
colClasses = colClasses,
col.names = col.names)
Alternatively specifying the col.names
as a string:
df <- read.csv(text="Date,File,User", colClasses = colClasses)
Thanks to Richard Scriven for the improvement
Probably nicer to use an extension method:
public static class StringExtensions
{
public static string Right(this string str, int length)
{
return str.Substring(str.Length - length, length);
}
}
Usage
string myStr = "PER 343573";
string subStr = myStr.Right(6);
If you're using Chimp / Webdriver.io, they support a lot more CSS selectors than the CSS spec.
This, for example, will click on the first anchor that contains the words "Bad bear":
browser.click("a*=Bad Bear");
First, build -> clean project -> rebuild it again.
If its not working, then in your build.gradle
, set the multiDexEnabled
as true
eg:
defaultConfig {
applicationId "com.example.myapplication"
minSdkVersion 21
targetSdkVersion 27
multiDexEnabled true
versionCode 1
versionName "1.0"
testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner"
}
Try this:
You need to add left: 0
and right: 0
(not supported by IE6). Or specify a width
java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to id.co.bni.switcherservice.model.SwitcherServiceSource
Problem is
(List<SwitcherServiceSource>) LoadSource.list();
This will return a List of Object arrays (Object[]) with scalar values for each column in the SwitcherServiceSource
table. Hibernate will use ResultSetMetadata to deduce the actual order and types of the returned scalar values.
List<Object> result = (List<Object>) LoadSource.list();
Iterator itr = result.iterator();
while(itr.hasNext()){
Object[] obj = (Object[]) itr.next();
//now you have one array of Object for each row
String client = String.valueOf(obj[0]); // don't know the type of column CLIENT assuming String
Integer service = Integer.parseInt(String.valueOf(obj[1])); //SERVICE assumed as int
//same way for all obj[2], obj[3], obj[4]
}

Still not sure why the SQL Server 2008 version of SQLCMD doesn't work though..
Use the CSS pointer-events:none on fields you want to "disable" (possibly together with a greyed background) which allows the POST action, like:
<input type="text" class="disable">
.disable{
pointer-events:none;
background:grey;

I'm not sure the NDK provides full coverage of the official Java API.
From http://developer.android.com/sdk/ndk/index.html#overview :
Please note that the NDK does not enable you to develop native-only applications. Android's primary runtime remains the Dalvik virtual machine.
For others who land here in the future (including myself), add a -name option to find specific file types, for instance: find /var -name "*.php" -mtime -1 -ls

this activity display progress for 3sec then it will display listview, instead of adding data statically to stringValues list you can get data from server in doInBackground() and display it.
your panel class don't have a constructor that accepts a string
try change
RLS_strid_panel p = new RLS_strid_panel(namn1);
to
RLS_strid_panel p = new RLS_strid_panel();
p.setName1(name1);
You can use margin for .wrap container instead of padding for .wrapper:
body{ height:20000px }
#wrapper { padding: 0%; }
#wrap{
float: left;
position: relative;
margin: 10%;
width: 40%;
background:#ccc;
}
#fixed{
position:fixed;
width:inherit;
padding:0px;
height:10px;
background-color:#333;
}
A simple way using std::next_permutation
:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.end() - r, v.end(), true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::next_permutation(v.begin(), v.end()));
return 0;
}
or a slight variation that outputs the results in an easier to follow order:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.begin(), v.begin() + r, true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::prev_permutation(v.begin(), v.end()));
return 0;
}
A bit of explanation:
It works by creating a "selection array" (v
), where we place r
selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v
.
You can implement it if you note that for each level r you select a number from 1 to n.
In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance
#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>
using namespace std;
struct combinations
{
typedef vector<int> combination_t;
// initialize status
combinations(int N, int R) :
completed(N < 1 || R > N),
generated(0),
N(N), R(R)
{
for (int c = 1; c <= R; ++c)
curr.push_back(c);
}
// true while there are more solutions
bool completed;
// count how many generated
int generated;
// get current and compute next combination
combination_t next()
{
combination_t ret = curr;
// find what to increment
completed = true;
for (int i = R - 1; i >= 0; --i)
if (curr[i] < N - R + i + 1)
{
int j = curr[i] + 1;
while (i <= R-1)
curr[i++] = j++;
completed = false;
++generated;
break;
}
return ret;
}
private:
int N, R;
combination_t curr;
};
int main(int argc, char **argv)
{
int N = argc >= 2 ? atoi(argv[1]) : 5;
int R = argc >= 3 ? atoi(argv[2]) : 2;
combinations cs(N, R);
while (!cs.completed)
{
combinations::combination_t c = cs.next();
copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
cout << endl;
}
return cs.generated;
}
test output:
1,2,
1,3,

You'll get that error once your numbers are greater than sys.maxsize
:
>>> p = [sys.maxsize]
>>> preds[0] = p
>>> p = [sys.maxsize+1]
>>> preds[0] = p
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long
You can confirm this by checking:
>>> import sys
>>> sys.maxsize
2147483647
To take numbers with larger precision, don't pass an int type which uses a bounded C integer behind the scenes. Use the default float:
>>> preds = np.zeros((1, 3))
For me its a permissions issue:
On the git server run this command on the repo directory
sudo chmod -R 777 theDirectory/
I you're on windows, you can use powershell to do this:
git branch | grep 'feature/*' |% { git branch -D $_.trim() }
replace feature/*
with any pattern you like.
I've had bad luck with this answer, with the process (Wix light.exe) essentially going out to lunch and not coming home in time for dinner. However, the following worked well for me:
Process p = new Process();
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
// etc, then start process
Use a semaphore with a count that is equal to the number of readers. Let each reader take one count of the semaphore in order to read, that way they can all read at the same time. Then let the writer take ALL the semaphore counts prior to writing. This causes the writer to wait for all reads to finish and then block out reads while writing.
