I was able to fix this by running the command prompt/bash as admin and closing VSCode! Seems like VSCode was locking some files. Potentially something else could be locking these files for you.
A colleague told me to use scm.branches[0].name
and it worked. I wrapped it to a function in my Jenkinsfile:
def getGitBranchName() {
return scm.branches[0].name
}
For me, brew
had updated the gnupg
or gpg
so all I had to do to fix this is.
brew link --overwrite gnupg
That linked the gpg
to the right place, as I can confirm via which gpg
and everything worked after that.
This may or may not help you address your problem, OP, but to get the timezone of the current server relative to UTC (UT1, technically), do:
SELECT EXTRACT(TIMEZONE FROM now())/3600.0;
The above works by extracting the UT1-relative offset in minutes, and then converting it to hours using the factor of 3600 secs/hour.
Example:
SET SESSION timezone TO 'Asia/Kabul';
SELECT EXTRACT(TIMEZONE FROM now())/3600.0;
-- output: 4.5 (as of the writing of this post)
(docs).
First, run
sudo apt-get install nodejs-dev node-gyp libssl1.0-dev
then run
sudo apt install npm
Did you try format?
@font-face {
font-family: 'The name of the Font Family Here';
src: URL('font.ttf') format('truetype');
}
Read this article: http://css-tricks.com/snippets/css/using-font-face/
Also, might depend on browser as well.
AND
between ORDER BY
and LIMIT
=
between ORDER BY
, LIMIT
keywords and conditionSo you query will look like:
SELECT post_datetime
FROM post
WHERE type = 'published'
ORDER BY post_datetime DESC
LIMIT 3
By using https://github.com/nick318/FindElementInFrames You can find webElement across all frames:
SearchByFramesFactory searchFactory = new SearchByFramesFactory(driver);
SearchByFrames searchInFrame = searchFactory.search(() -> driver.findElement(By.tagName("body")));
Optional<WebElement> elem = searchInFrame.getElem();
In your code j is Already json data and j['places'] is list not dict.
r = requests.get('http://api.zippopotam.us/us/ma/belmont')
j = r.json()
print j['state']
for each in j['places']:
print each['latitude']
Some time you have to give all the form element into a same div.
example:-
If you are using ajax submit with modal.
So all the elements are in modal body.
Some time we put submit button in modal footer.
First, the enum methods shouldn't be in all caps. They are methods just like other methods, with the same naming convention.
Second, what you are doing is not the best possible way to set up your enum. Instead of using an array of values for the values, you should use separate variables for each value. You can then implement the constructor like you would any other class.
Here's how you should do it with all the suggestions above:
public enum States {
...
MASSACHUSETTS("Massachusetts", "MA", true),
MICHIGAN ("Michigan", "MI", false),
...; // all 50 of those
private final String full;
private final String abbr;
private final boolean originalColony;
private States(String full, String abbr, boolean originalColony) {
this.full = full;
this.abbr = abbr;
this.originalColony = originalColony;
}
public String getFullName() {
return full;
}
public String getAbbreviatedName() {
return abbr;
}
public boolean isOriginalColony(){
return originalColony;
}
}
Try:
npm install underscore
:)
There is no unserscore package in npm registry.
Use this:
Format(Now, "MMMM dd, yyyy")

sudo brew is no longer an option so if you install with brew at this point you're going to get 2 really obnoxious things:
A: it likes to install into /usr/local/opts
or according to this, /usr/local/shared. This isn't a big deal at first but i've had issues with node PATH especially when I installed lint.
B: you're kind of stuck with sudo commands until you either uninstall and install it this way or you can get the stack from Bitnami
I recommend this method over the stack option because it's ready to go if you have multiple projects. If you go with the premade MEAN stack you'll have to set up virtual hosts in httpd.conf (more of a pain in this stack than XAMPP)plust the usual update your extra/vhosts.conf and /etc/hosts for every additional project, unless you want to repoint and restart your server when you get done updatading things.
OPT
ional
It holds optional software and packages that you install that are not required for the system to run.
You could set the width of the abbrev column to a fixed pixel width, then set the width of the description column to the width of the DataGridView, minus the sum of the widths of the other columns and some extra margin (if you want to prevent a horizontal scrollbar from appearing on the DataGridView):
dataGridView1.Columns[1].Width = 108; // or whatever width works well for abbrev
dataGridView1.Columns[2].Width =
dataGridView1.Width
- dataGridView1.Columns[0].Width
- dataGridView1.Columns[1].Width
- 72; // this is an extra "margin" number of pixels
If you wanted the description column to always take up the "remainder" of the width of the DataGridView, you could put something like the above code in a Resize
event handler of the DataGridView.
As per the documentation, most browsers will display the <ul>
, <ol>
and <li>
elements with the following default values:
Default CSS settings for UL or OL tag:
ul, ol {
display: block;
list-style: disc outside none;
margin: 1em 0;
padding: 0 0 0 40px;
}
ol {
list-style-type: decimal;
}
Default CSS settings for LI tag:
li {
display: list-item;
}
Style nested list items as well:
ul ul, ol ul {
list-style-type: circle;
margin-left: 15px;
}
ol ol, ul ol {
list-style-type: lower-latin;
margin-left: 15px;
}
Note: The result will be perfect if we use the above styles with a class. Also see different List-Item markers.
The right way to install grunt is by running this command:
npm install grunt -g
(Prepend "sudo" to the command above if you get a EACCESS error message)
-g will make npm install the package globally, so you will be able to use it whenever you want in your current machine.
Try adding a style="width:100%;" to the img tag. That way the image will fill up the entire width of the page, thus scaling down if the image is larger than the viewport.
I ran into the same situation where when I copied the formula to another cell the formula was still referencing the cell used in the first formula. To correct this when you set up the rules, select the option "use a formula to determine which cells to format. Then type in the box your formula, for example H23*.25. When you copy the cells down the formulas will change to H24*.25, H25*.25 and so on. Hope this helps.
Lets say your data is -
data = {'a': [ [1, 2] ], 'b': [ [3, 4] ],'c':[ [5,6]] }
You can use the data.items()
method to get the dictionary elements. Note, in django templates we do NOT put ()
. Also some users mentioned values[0]
does not work, if that is the case then try values.items
.
<table>
<tr>
<td>a</td>
<td>b</td>
<td>c</td>
</tr>
{% for key, values in data.items %}
<tr>
<td>{{key}}</td>
{% for v in values[0] %}
<td>{{v}}</td>
{% endfor %}
</tr>
{% endfor %}
</table>
Am pretty sure you can extend this logic to your specific dict.
To iterate over dict keys in a sorted order - First we sort in python then iterate & render in django template.
return render_to_response('some_page.html', {'data': sorted(data.items())})
In template file:
{% for key, value in data %}
<tr>
<td> Key: {{ key }} </td>
<td> Value: {{ value }} </td>
</tr>
{% endfor %}
I have tried to create an image to explain this in the most simple words
1) Authentication means "Are you who you say you are?"
2) Authorization means "Should you be able to do what you are trying to do?".
This is also described in the image below.
I have tried to explain it in the best terms possible, and created an image of the same.
CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(1);
See Here for more details.
Or
DateTime dt = DateTime.Now;
Console.WriteLine( dt.ToString( "MMMM" ) );
Or if you want to get the culture-specific abbreviated name.
GetAbbreviatedMonthName(1);
Full version:
<? echo date('F Y'); ?>
Short version:
<? echo date('M Y'); ?>
Here is a good reference for the different date options.
update
To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp
parameter for the date() function. Like this:
echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));
This will also work (it's typically used to get the last day of the previous month):
echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));
Hope that helps.
Since you've already received help on the query, I'll take a poke at your syntax question:
The first query employs some lesser-known ANSI SQL syntax which allows you to nest joins between the join
and on
clauses. This allows you to scope/tier your joins and probably opens up a host of other evil, arcane things.
Now, while a nested join cannot refer any higher in the join hierarchy than its immediate parent, joins above it or outside of its branch can refer to it... which is precisely what this ugly little guy is doing:
select
count(*)
from Table1 as t1
join Table2 as t2
join Table3 as t3
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
This looks a little confusing because join #2 is joining t1 to t2 without specifically referencing t2... however, it references t2 indirectly via t3 -as t3 is joined to t2 in join #1. While that may work, you may find the following a bit more (visually) linear and appealing:
select
count(*)
from Table1 as t1
join Table3 as t3
join Table2 as t2
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
Personally, I've found that nesting in this fashion keeps my statements tidy by outlining each tier of the relationship hierarchy. As a side note, you don't need to specify inner. join is implicitly inner unless explicitly marked otherwise.
In C++11 and beyond, you can use the back
member function:
char ch = myStr.back();
In C++03, std::string::back
is not available due to an oversight, but you can get around this by dereferencing the reverse_iterator
you get back from rbegin
:
char ch = *myStr.rbegin();
In both cases, be careful to make sure the string actually has at least one character in it! Otherwise, you'll get undefined behavior, which is a Bad Thing.
Hope this helps!
You can also use sentence tokenization function in NLTK:
from nltk.tokenize import sent_tokenize
sentence = "As the most quoted English writer Shakespeare has more than his share of famous quotes. Some Shakespare famous quotes are known for their beauty, some for their everyday truths and some for their wisdom. We often talk about Shakespeare’s quotes as things the wise Bard is saying to us but, we should remember that some of his wisest words are spoken by his biggest fools. For example, both ‘neither a borrower nor a lender be,’ and ‘to thine own self be true’ are from the foolish, garrulous and quite disreputable Polonius in Hamlet."
sent_tokenize(sentence)
import json
d = json.loads(j)
print d['glossary']['title']
Create a reverse dictionary using the calendar
module (which, like any module, you will need to import):
{month: index for index, month in enumerate(calendar.month_abbr) if month}
In Python versions before 2.7, due to dict comprehension syntax not being supported in the language, you would have to do
dict((month, index) for index, month in enumerate(calendar.month_abbr) if month)
I would just use this small extension to Date
- http://blog.stevenlevithan.com/archives/date-time-format
var date = new Date(msSinceEpoch);
date.format("isoDateTime"); // 2007-06-09T17:46:21
You are probably using a locale where the month names are not "January", "February", etc. but some other words in your local language.
Try specifying the locale you wish to use, for example Locale.US
:
DateFormat fmt = new SimpleDateFormat("MMMM dd, yyyy", Locale.US);
Date d = fmt.parse("June 27, 2007");
Also, you have an extra space in the date string, but actually this has no effect on the result. It works either way.

I have used it in many projects, sharing to help you. Thanks for asking this question.
This is typically done using an edit distance measure. Searching for "edit distance java" turns up a number of libraries, like this one.
I can't see that you're adding these controls to the control hierarchy. Try:
Controls.Add ( ddlCountries );
Controls.Add ( ddlStates );
Events won't be invoked unless the control is part of the control hierarchy.
Mixture of all solutions :-)

set print elements 0
set print elements
number-of-elements
Set a limit on how many elements of an array GDB will print. If GDB is printing a large array, it stops printing after it has printed the number of elements set by the set print elements
command. This limit also applies to the display of strings. When GDB starts, this limit is set to 200. Setting number-of-elements to zero means that the printing is unlimited.
Since there is chance of error in word, think about using SOUNDEX combined with LCS algorithm to compare strings, this will help a lot !
You can globally set printing options. I think this should work:
Method 1:
pd.set_option('display.max_columns', None)
pd.set_option('display.max_rows', None)
Method 2:
pd.options.display.max_columns = None
pd.options.display.max_rows = None
This will allow you to see all column names & rows when you are doing .head()
. None of the column name will be truncated.
If you just want to see the column names you can do:
print(df.columns.tolist())
Using pygame, you can open a window, get the surface as an array of pixels, and manipulate as you want from there. You'll need to copy your numpy array into the surface array, however, which will be much slower than doing actual graphics operations on the pygame surfaces themselves.
Yes, you can concatenate using a +
sign. Kotlin has string templates, so it's better to use them like:
var fn = "Hello"
var ln = "World"
"$fn $ln"
for concatenation.
You can even use String.plus()
method.
SELECT date1 - date2
FROM some_table
returns a difference in days. Multiply by 24 to get a difference in hours and 24*60 to get minutes. So
SELECT (date1 - date2) * 24 * 60 difference_in_minutes
FROM some_table
should be what you're looking for
A technique I use is something like the following. Define a global variable that you can use for one or multiple try catch blocks depending on what you're trying to debug and use the following structure:
if(!GlobalTestingBool)
{
try
{
SomeErrorProneMethod();
}
catch (...)
{
// ... Error handling ...
}
}
else
{
SomeErrorProneMethod();
}
I find this gives me a bit more flexibility in terms of testing because there are still some exceptions I don't want the IDE to break on.
How about calling a function from within your callback instead of returning a value in sync_call()?
function sync_call(input) {
var value;
// Assume the async call always succeed
async_call(input, function(result) {
value = result;
use_value(value);
} );
}
Add a log4j.properties(log4j.xml) file with at least one appender in root of your classpath.
The contents of the file(log4j.properties) can be as simple as
log4j.rootLogger=WARN,A1
# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{ISO8601} [%t] %-5p %c %x - %m%n
This will enable log4j logging with default log level as WARN
and use the java console to log the messages.
You have to read the API carefully for this methods. Sometimes you can get confused very easily.
It is either:
if (B.class.isInstance(view))
API says: Determines if the specified Object (the parameter) is assignment-compatible with the object represented by this Class (The class object you are calling the method at)
or:
if (B.class.isAssignableFrom(view.getClass()))
API says: Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter
or (without reflection and the recommended one):
if (view instanceof B)
SELECT CUSTOMER, COUNT(*) as PETS
FROM table_name
GROUP BY CUSTOMER;
Little side note for anyone new to Python who didn't figure it out by theirself: this should be automatic when installing Python, but just in case, note that to run Python using the python
command in Windows' CMD you must first add it to the PATH
environment variable, as explained here.
To execute Pip, first of all make sure you have it installed, so type in your CMD:
> python
>>> import pip
>>>
And it should proceed with no error. Otherwise, if this fails, you can look here to see how to install it. Now that you are sure you've got Pip, you can run it from CMD with Python using the -m
(module) parameter, like this:
> python -m pip <command> <args>
Where <command>
is any Pip command you want to run, and <args>
are its relative arguments, separated by spaces.
For example, to install a package:
> python -m pip install <package-name>
A referral was returned from the server error usually means that the IP address is not hosted by the domain that is provided on the connection string. For more detail, see this link:
Referral was returned AD Provider
To illustrate the problem, we define two IP addresses hosted on different domains:
IP Address DC Name Notes
172.1.1.10 ozkary.com Production domain
172.1.30.50 ozkaryDev.com Development domain
If we defined a LDAP connection string with this format:
LDAP://172.1.1.10:389/OU=USERS,DC=OZKARYDEV,DC=COM
This will generate the error because the IP is actually on the OZKARY DC not the OZKARYDEV DC. To correct the problem, we would need to use the IP address that is associated to the domain.
You should not extend the JFrame
class unnecessarily (only if you are adding extra functionality to the JFrame
class)
JFrame:
JFrame
extends Component
and Container
.
It is a top level container used to represent the minimum requirements for a window. This includes Border
s, resizability (is the JFrame
resizeable?), title bar, controls (minimize/maximize allowed?), and event handlers for various Event
s like windowClose
, windowOpened
etc.
JPanel:
JPanel
extends Component
, Container
and JComponent
It is a generic class used to group other Component
s together.
It is useful when working with LayoutManager
s e.g. GridLayout
f.i adding components to different JPanel
s which will then be added to the JFrame
to create the gui. It will be more manageable in terms of Layout
and re-usability.
It is also useful for when painting/drawing in Swing, you would override paintComponent(..)
and of course have the full joys of double buffering.
A Swing GUI cannot exist without a top level container like (JWindow
, Window
, JFrame
Frame
or Applet
), while it may exist without JPanel
s.
If choosing between OAuth versions, go with OAuth 2.0.
OAuth bearer tokens should only be used with a secure transport.
OAuth bearer tokens are only as secure or insecure as the transport that encrypts the conversation. HTTPS takes care of protecting against replay attacks, so it isn't necessary for the bearer token to also guard against replay.
While it is true that if someone intercepts your bearer token they can impersonate you when calling the API, there are plenty of ways to mitigate that risk. If you give your tokens a long expiration period and expect your clients to store the tokens locally, you have a greater risk of tokens being intercepted and misused than if you give your tokens a short expiration, require clients to acquire new tokens for every session, and advise clients not to persist tokens.
If you need to secure payloads that pass through multiple participants, then you need something more than HTTPS/SSL, since HTTPS/SSL only encrypts one link of the graph. This is not a fault of OAuth.
Bearer tokens are easy to for clients to obtain, easy for clients to use for API calls and are widely used (with HTTPS) to secure public facing APIs from Google, Facebook, and many other services.
Your question is how to randomize a list. This means:
A large number of the answers posted for this question do NOT satisfy the two requirements above for being "random".
Here's a compact, non-biased pseudo-random function following the Fisher-Yates shuffle method.
public static void Shuffle<T>(this IList<T> list, Random rnd)
{
for (var i = list.Count-1; i > 0; i--)
{
var randomIndex = rnd.Next(i + 1); //maxValue (i + 1) is EXCLUSIVE
list.Swap(i, randomIndex);
}
}
public static void Swap<T>(this IList<T> list, int indexA, int indexB)
{
var temp = list[indexA];
list[indexA] = list[indexB];
list[indexB] = temp;
}
Update: There's now a native way to achieve this. Node.contains()
. Mentioned in comment and below answers as well.
Old answer:
Using the parentNode
property should work. It's also pretty safe from a cross-browser standpoint. If the relationship is known to be one level deep, you could check it simply:
if (element2.parentNode == element1) { ... }
If the the child can be nested arbitrarily deep inside the parent, you could use a function similar to the following to test for the relationship:
function isDescendant(parent, child) {
var node = child.parentNode;
while (node != null) {
if (node == parent) {
return true;
}
node = node.parentNode;
}
return false;
}
Necromancing.
Providing an actual answer.
What is the difference between .Net Core and Mono?
.NET Core now officially is the future of .NET. It started for most part with a re-write of the ASP.NET MVC framework and console applications, which of course includes server applications. (Since it's Turing-complete and supports interop with C dlls, you could, if you absolutely wanted to, also write your own desktop applications with it, for example through 3rd-party libraries like Avalonia, which were a bit very basic at the time I first wrote this, which meant you were pretty much limited to web or server stuff.) Over time, many APIs have been added to .NET Core, so much so that after version 3.1, .NET Core will jump to version 5.0, be known as .NET 5.0 without the "Core", and that then will be the future of the .NET Framework. What used to be the full .NET Framework will linger around in maintenance mode as Full .NET Framework 4.8.x for a few decades, until it will die (maybe there are still going to be some upgrades, but I doubt it). In other words, .NET Core is the future of .NET, and Full .NET Framework will go the way of the Dodo/Silverlight/WindowsPhone.
The main point of .NET Core, apart from multi-platform support, is to improve performance, and to enable "native compilation"/self-contained-deployment (so you don't need .NET framework/VM installed on the target machine.
On the one hand, this means docker.io support on Linux, and on the other, self-contained deployment is useful in "cloud-computing", since then you can just use whatever version of the dotnet-CORE framework you like, and you don't have to worry about which version(s) of the .NET framework the sysadmin has actually installed.
While the .NET Core runtime supports multiple operating systems and processors, the SDK is a different story. And while the SDK supports multiple OS, ARM support for the SDK is/was still work in progress. .NET Core is supported by Microsoft. Dotnet-Core did not come with WinForms or WPF or anything like that.
"The Mono Project" is much older than .NET Core.
Mono is Spanish and means Monkey, and as a side-remark, the name has nothing to do with mononucleosis (hint: you could get a list of staff under http://primates.ximian.com/).
Mono was started in 2005 by Miguel de Icaza (the guy that started GNOME - and a few others) as an implementation of the .NET Framework for Linux (Ximian/SuSe/Novell). Mono includes Web-Forms, Winforms, MVC, Olive, and an IDE called MonoDevelop (also knows as Xamarin Studio or Visual Studio Mac). Basically the equivalent of (OpenJDK) JVM and (OpenJDK) JDK/JRE (as opposed to SUN/Oracle JDK). You can use it to get ASP.NET-WebForms + WinForms + ASP.NET-MVC applications to work on Linux.
Mono is supported by Xamarin (the new company name of what used to be Ximian, when they focused on the Mobile market, instead of the Linux market), and not by Microsoft.
(since Xamarin was bought by Microsoft, that's technically [but not culturally] Microsoft.)
You will usually get your C# stuff to compile on mono, but not the VB.NET stuff.
Mono misses some advanced features, like WSE/WCF and WebParts.
Many of the Mono implementations are incomplete (e.g. throw NotImplementedException in ECDSA encryption), buggy (e.g. ODBC/ADO.NET with Firebird), behave differently than on .NET (for example XML-serialization) or otherwise unstable (ASP.NET MVC) and unacceptably slow (Regex). On the upside, the Mono toolchain also works on ARM.
As far as .NET Core is concerned, when they say cross-platform, don't expect that cross-platform means that you could actually just apt-get install .NET Core on ARM-Linux, like you can with ElasticSearch. You'll have to compile the entire framework from source.
That is, if you have that space (e.g. on a Chromebook, which has a 16 to 32 GB total HD).
It also used to have issues of incompatibility with OpenSSL 1.1 and libcurl.
Those have been rectified in the latest version of .NET Core Version 2.2.
So much for cross-platform.
I found a statement on the official site that said, "Code written for it is also portable across application stacks, such as Mono".
As long as that code doesn't rely on WinAPI-calls, Windows-dll-pinvokes, COM-Components, a case-insensitive file system, the default-system-encoding (codepage) and doesn't have directory separator issues, that's correct. However, .NET Core code runs on .NET Core, and not on Mono. So mixing the two will be difficult. And since Mono is quite unstable and slow (for web applications), I wouldn't recommend it anyway. Try image-processing on .NET core, e.g. WebP or moving GIF or multipage-tiff or writing text on an image, you'll be nastily surprised.
Note:
As of .NET Core 2.0, there is System.Drawing.Common (NuGet), which contains most of the functionality of System.Drawing. It should be more or less feature-complete in .NET-Core 2.1. However, System.Drawing.Common uses GDI+, and therefore won't work on Azure (System.Drawing libraries are available in Azure Cloud Service [basically just a VM], but not in Azure Web App [basically shared hosting?])
So far, System.Drawing.Common works fine on Linux/Mac, but has issues on iOS/Android - if it works at all, there.
Prior to .NET Core 2.0, that is to say sometime mid-February 2017, you could use SkiaSharp for imaging (example) (you still can).
Post .net-core 2.0, you'll notice that SixLabors ImageSharp is the way to go, since System.Drawing is not necessarely secure, and has a lot of potential or real memory leaks, which is why you shouldn't use GDI in web-applications; Note that SkiaSharp is a lot faster than ImageSharp, because it uses native-libraries (which can also be a drawback). Also, note that while GDI+ works on Linux & Mac, that doesn't mean it works on iOS/Android.
Code not written for .NET (non-Core) is not portable to .NET Core.
Meaning, if you want a non-GPL C# library like PDFSharp to create PDF-documents (very commonplace), you're out of luck (at the moment) (not anymore). Never mind ReportViewer control, which uses Windows-pInvokes (to encrypt, create mcdf documents via COM, and to get font, character, kerning, font embedding information, measure strings and do line-breaking, and for actually drawing tiffs of acceptable quality), and doesn't even run on Mono on Linux
(I'm working on that).
Also, code written in .NET Core is not portable to Mono, because Mono lacks the .NET Core runtime libraries (so far).
My goal is to use C#, LINQ, EF7, visual studio to create a website that can be ran/hosted in linux.
EF in any version that I tried so far was so goddamn slow (even on such simple things like one table with one left-join), I wouldn't recommend it ever - not on Windows either.
I would particularly not recommend EF if you have a database with unique-constrains, or varbinary/filestream/hierarchyid columns. (Not for schema-update either.)
And also not in a situation where DB-performance is critical (say 10+ to 100+ concurrent users).
Also, running a website/web-application on Linux will sooner or later mean you'll have to debug it.
There is no debugging support for .NET Core on Linux. (Not anymore, but requires JetBrains Rider.)
MonoDevelop does not (yet) support debugging .NET Core projects.
If you have problems, you're on your own. You'll have to use extensive logging.
Be careful, be advised extensive logging will fill your disk in no time, particularly if your program enters an infinite loop or recursion.
This is especially dangerous if your web-app runs as root, because log-in requires logfile-space - if there's no free space left, you won't be able to login anymore.
(Normally, about 5% of diskspace is reserved for user root [aka administrator on Windows], so at least the administrator can still log in if the disk is almost full. But if your applications run as root, that restriction does not apply for their disk usage, and so their logfiles can use 100% of the remaining free space, so not even the administrator can log in any more.)
It's therefore better not to encrypt that disk, that is, if you value your data/system.
Someone told me that he wanted it to be "in Mono", but I don't know what that means.
It either means he doesn't want to use .NET Core, or he just wants to use C# on Linux/Mac. My guess is he just wants to use C# for a Web-App on Linux. .NET Core is the way to go for that, if you absolutely want to do it in C#. Don't go with "Mono proper"; on the surface, it would seem to work at first - but believe me you will regret it because Mono's ASP.NET MVC isn't stable when your server runs long-term (longer than 1 day) - you have now been warned. See also the "did not complete" references when measuring Mono performance on the techempower benchmarks.
I know I want to use the .Net Core 1.0 framework with the technologies I listed above. He also said he wanted to use "fast cgi". I don't know what that means either.
It means he wants to use a high-performance full-featured WebServer like nginx (Engine-X), possibly Apache.
Then he can run mono/dotnetCore with virtual name based hosting (multiple domain names on the same IP) and/or load-balancing. He can also run other websites with other technologies, without requiring a different port-number on the web-server. It means your website runs on a fastcgi-server, and nginx forwards all web-requests for a certain domain via the fastcgi-protocol to that server. It also means your website runs in a fastcgi-pipeline, and you have to be careful what you do, e.g. you can't use HTTP 1.1 when transmitting files.
Otherwise, files will be garbled at the destination.
See also here and here.
To conclude:
.NET Core at present (2016-09-28) is not really portable, nor is is really cross-platform (in particular the debug-tools).
Nor is native-compilation easy, especially for ARM.
And to me, it also does not look like its development is "really finished", yet.
For example, System.Data.DataTable/DataAdaper.Update is missing...
(not anymore with .NET Core 2.0)
Together with the System.Data.Common.IDB* interfaces. (not anymore with .NET Core 1.1)
if there ever was one class that is often used, DataTable/DataAdapter would be it...
Also, the Linux-installer (.deb) fails, at least on my machine, and I'm sure I'm not the only one that has that problem.
Debug, maybe with Visual Studio Code, if you can build it on ARM (I managed to do that - do NOT follow Scott Hanselman's blog-post if you do that - there's a howto in the wiki of VS-Code on github), because they don't offer the executable.
Yeoman also fails. (I guess it has something to do with the nodejs version you installed - VS Code requires one version, Yeoman another... but it should run on the same computer. pretty lame
Never mind that it should run on the node version shipped by default on the OS.
Never mind that there should be no dependency on NodeJS in the first place.
The kestell server is also work in progress.
And judging by my experience with the mono-project, I highly doubt they ever tested .NET Core on FastCGI, or that they have any idea what FastCGI-support means for their framework, let alone that they tested it to make sure "everything works". In fact, I just tried making a fastcgi-application with .NET Core and just realized there is no FastCGI library for .NET Core "RTM"...
So when you're going to run .NET Core "RTM" behind nginx, you can only do it by proxying requests to kestrell (that semi-finished nodeJS-derived web-server) - there's no fastcgi support at present in .NET Core "RTM", AFAIK. Since there is no .net core fastcgi library, and no samples, it's also highly unlikely that anybody did any testing on the framework to make sure fastcgi works as expected.
I also question the performance.
In the (preliminary) techempower-benchmark (round 13), aspnetcore-linux ranks on 25% relative to the best performance, while comparable frameworks like Go (golang) rank at 96.9% of peak performance (and that is when returning plaintext without file-system access only). .NET Core does a little better on JSON-serialization, but it does not look compelling either (go reaches 98.5% of peak, .NET core 65%). That said, it can't possibly be worse than "mono proper".
Also, since it's still relatively new, not all of the major libraries have been ported (yet), and I doubt that some of them will ever be ported.
Imaging support is also questionable at best.
For anything encryption, use BouncyCastle instead.
Can you help me make sense of all these terms and if my expectations are realistic?
I hope i helped you making more sense with all these terms.
As far as your expecations go:
Developing a Linux application without knowing anything about Linux is a really stupid idea in the first place, and it's also bound to fail in some horrible way one way or the other. That said, because Linux comes at no licensing costs, it's a good idea in principle, BUT ONLY IF YOU KNOW WHAT YOU DO.
Developing an application for a platform where you can't debug your application on is another really bad idea.
Developing for fastcgi without knowing what consequences there are is yet another really bad idea.
Doing all these things on a "experimental" platform without any knowledge of that platform's specifics and without debugging support is suicide, if your project is more than just a personal homepage. On the other hand, I guess doing it with your personal homepage for learning purposes would probably be a very good experience - then you get to know what the framework and what the non-framework problems are.
You can for example (programmatically) loop-mount a case-insensitive fat32, hfs or JFS for your application, to get around the case-sensitivity issues (loop-mount not recommended in production).
To summarize
At present (2016-09-28), I would stay away from .NET Core (for production usage). Maybe in one to two years, you can take another look, but probably not before.
If you have a new web-project that you develop, start it in .NET Core, not mono.
If you want a framework that works on Linux (x86/AMD64/ARMhf) and Windows and Mac, that has no dependencies, i.e. only static linking and no dependency on .NET, Java or Windows, use Golang instead. It's more mature, and its performance is proven (Baidu uses it with 1 million concurrent users), and golang has a significantly lower memory footprint. Also golang is in the repositories, the .deb installs without problems, the sourcecode compiles - without requiring changes - and golang (in the meantime) has debugging support with delve and JetBrains Gogland on Linux (and Windows and Mac). Golang's build process (and runtime) also doesn't depend on NodeJS, which is yet another plus.
As far as mono goes, stay away from it.
It is nothing short of amazing how far mono has come, but unfortunately that's no substitute for its performance/scalability and stability issues for production applications.
Also, mono-development is quite dead, they largely only develop the parts relevant to Android and iOS anymore, because that's where Xamarin makes their money.
Don't expect Web-Development to be a first-class Xamarin/mono citizen.
.NET Core might be worth it, if you start a new project, but for existing large web-forms projects, porting over is largely out of the question, the changes required are huge. If you have a MVC-project, the amount of changes might be manageable, if your original application design was sane, which is mostly not the case for most existing so-called "historically grown" applications.
December 2016 Update:
Native compilation has been removed from .NET Core preview, as it is not yet ready...
Seems like they have improved pretty heavily on the raw text-file benchmark, but on the other hand, it's gotten pretty buggy. Also, it further deteriorated in the JSON benchmarks. Curious also that entity framework shall be faster for updates than Dapper - although both at record slowness. This is very unlikely to be true. Looks like there still are more than just a few bugs to hunt.
Also, there seems to be relief coming on the Linux IDE front.
JetBrains released "Project Rider", an early access preview of a C#/.NET Core IDE for Linux (and Mac and Windows), that can handle Visual Studio Project files.
Finally a C# IDE that is usable & that isn't slow as hell.
Conclusion: .NET Core still is pre-release quality software as we march into 2017. Port your libraries, but stay away from it for production usage, until framework quality stabilizes.
And keep an eye on Project Rider.
2017 Update
Have migrated my (brother's) homepage to .NET Core for now.
So far, the runtime on Linux seems to be stable enough (at least for small projects) - it survived a load test with ease - mono never did.
Also, it looks like I mixed up .NET-Core-native and .NET-Core-self-contained-deployment. Self-contained deployment works, but it is a bit underdocumented, although it's super easy (the build/publish tools are a bit unstable, yet - if you encounter "Positive number required. - Build FAILED." - run the same command again, and it works).
You can run
dotnet restore -r win81-x64
dotnet build -r win81-x64
dotnet publish -f netcoreapp1.1 -c Release -r win81-x64
Note: As per .NET Core 3, you can publish everything minified as a single file:
dotnet publish -r win-x64 -c Release /p:PublishSingleFile=true
dotnet publish -r linux-x64 -c Release /p:PublishSingleFile=true
However, unlike go, it's not a statically linked executable, but a self-extracting zip file, so when deploying, you might run into problems, especially if the temp directory is locked down by group policy, or some other issues. Works fine for a hello-world program, though. And if you don't minify, the executable size will clock in at something around 100 MB.
And you get a self-contained .exe-file (in the publish directory), which you can move to a Windows 8.1 machine without .NET framework installed and let it run. Nice. It's here that dotNET-Core just starts to get interesting. (mind the gaps, SkiaSharp doesn't work on Windows 8.1 / Windows Server 2012 R2, [yet] - the ecosystem has to catch up first - but interestingly, the Skia-dll-load-fail doesn't crash the entire server/application - so everything else works)
(Note: SkiaSharp on Windows 8.1 is missing the appropriate VC runtime files - msvcp140.dll and vcruntime140.dll. Copy them into the publish-directory, and Skia will work on Windows 8.1.)
August 2017 Update
.NET Core 2.0 released.
Be careful - comes with (huge breaking) changes in authentication...
On the upside, it brought the DataTable/DataAdaper/DataSet classes back, and many more.
Realized .NET Core is still missing support for Apache SparkSQL, because Mobius isn't yet ported. That's bad, because that means no SparkSQL support for my IoT Cassandra Cluster, so no joins...
Experimental ARM support (runtime only, not SDK - too bad for devwork on my Chromebook - looking forward to 2.1 or 3.0).
PdfSharp is now experimentally ported to .NET Core.
JetBrains Rider left EAP. You can now use it to develop & debug .NET Core on Linux - though so far only .NET Core 1.1 until the update for .NET Core 2.0 support goes live.
May 2018 Update
.NET Core 2.1 release imminent.
Maybe this will fix NTLM-authentication on Linux (NTLM authentication doesn't work on Linux {and possibly Mac} in .NET-Core 2.0 with multiple authenticate headers, such as negotiate, commonly sent with ms-exchange, and they're apparently only fixing it in v2.1, no bugfix release for 2.0).
But I'm not installing preview releases on my machine. So waiting.
v2.1 is also said to greatly reduce compile times. That would be good.
Also, note that on Linux, .NET Core is 64-Bit only !
There is no, and there will be no, x86-32 version of .NET Core on Linux.
And the ARM port is ARM-32 only. No ARM-64, yet.
And on ARM, you (at present) only have the runtime, not the dotnet-SDK.
And one more thing:
Because .NET-Core uses OpenSSL 1.0, .NET Core on Linux doesn't run on Arch Linux, and by derivation not on Manjaro (the most popular Linux distro by far at this point in time), because Arch Linux uses OpenSSL 1.1. So if you're using Arch Linux, you're out of luck (with Gentoo, too).
Edit:
Latest version of .NET Core 2.2+ supports OpenSSL 1.1. So you can use it on Arch or (k)Ubuntu 19.04+. You might have to use the .NET-Core install script though, because there are no packages, yet.
On the upside, performance has definitely improved:
.NET Core 3:
.NET-Core v 3.0 is said to bring WinForms and WPF to .NET-Core.
However, while WinForms and WPF will be .NET Core, WinForms and WPF in .NET-Core will run on Windows only, because WinForms/WPF will use the Windows-API.
Note:
.NET Core 3.0 is now out (RTM), and there is WinForms and WPF support, but only for C# (on Windows). There is no WinForms-Core-Designer. The designer will, eventually, come with a Visual Studio update, somewhen. WinForms support for VB.NET is not supported, but is planned for .NET 5.0 somewhen in 2020.
PS:
echo "DOTNET_CLI_TELEMETRY_OPTOUT=1" >> /etc/environment
export DOTNET_CLI_TELEMETRY_OPTOUT=1
If you've used it on windows, you probably never saw this:
The .NET Core tools collect usage data in order to improve your experience.
The data is anonymous and does not include command-line arguments.
The data is collected by Microsoft and shared with the community.
You can opt out of telemetry by setting a DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1 using your favorite shell.
You can read more about .NET Core tools telemetry @ https://aka.ms/dotnet-cli-telemetry.
I thought I'd mention that I think monodevelop (aka Xamarin Studio, the Mono IDE, or Visual Studio Mac as it is now called on Mac) has evolved quite nicely, and is - in the meantime - largely usable.
However, JetBrains Rider (2018 EAP at this point in time) is definitely a lot nicer and more reliable (and the included decompiler is a life-safer), that is to say, if you develop .NET-Core on Linux or Mac. MonoDevelop does not support Debug-StepThrough on Linux in .NET Core, though, since MS does not license their debugging API dll (except for VisualStudio Mac ... ). However, you can use the Samsung debugger for .NET Core through the .NET Core debugger extension for Samsung Debugger for MonoDevelop
Disclaimer:
I don't use Mac, so I can't say if what I wrote here applies to FreeBSD-Unix based Mac as well. I am refering to the Linux (Debian/Ubuntu/Mint) version of JetBrains Rider, mono, MonoDevelop/VisualStudioMac/XamarinStudio and .NET-Core. Also, Apple is contemplating a move from Intel-processors to self-manufactured ARM(ARM-64?)-based processors, so much of what applies to Mac right now might not apply to Mac in the future (2020+).
Also, when I write "mono is quite unstable and slow", the unstable relates to WinFroms & WebForms applications, specifically executing web-applications via fastcgi or with XSP (on the 4.x version of mono), as well as XML-serialization-handling peculiarities, and the quite-slow relates to WinForms, and regular expressions in particular (ASP.NET-MVC uses regular expressions for routing as well).
When I write about my experience about mono 2.x, 3.x and 4.x, that also does not necessarely mean these issues haven't been resolved by now, or by the time you are reading this, nor that if they are fixed now, that there can't be a regression later that reintroduces any of these bugs/features. Nor does that mean that if you embed the mono-runtime, you'll get the same results as when you use the (dev) system's mono runtime. It also doesn't mean that embedding the mono-runtime (anywhere) is necessarely free.
All that doesn't necessarely mean mono is ill-suited for iOS or Android, or that it has the same issues there. I don't use mono on Android or IOS, so I'm in no positon to say anything about stability, usability, costs and performance on these platforms. Obviously, if you use .NET on Android, you have some other costs considerations to do as well, such as weighting xamarin-costs vs. costs and time for porting existing code to Java. One hears mono on Android and IOS shall be quite good. Take it with a grain of salt. For one, don't expect the default-system-encoding to be the same on android/ios vs. Windows, and don't expect the android filesystem to be case-insensitive, and don't expect any windows fonts to be present.

The problem seems to be that you expect plt.show()
to show the window and then to return. It does not do that. The program will stop at that point and only resume once you close the window. You should be able to test that: If you close the window and then another window should pop up.
To resolve that problem just call plt.show()
once after your loop. Then you get the complete plot. (But not a 'real-time plotting')
You can try setting the keyword-argument block
like this: plt.show(block=False)
once at the beginning and then use .draw()
to update.

When we want to get multiple elements from a List into a new list (filter using a predicate) and remove them from the existing list, I could not find a proper answer anywhere.
Here is how we can do it using Java Streaming API partitioning.
Map<Boolean, List<ProducerDTO>> classifiedElements = producersProcedureActive
.stream()
.collect(Collectors.partitioningBy(producer -> producer.getPod().equals(pod)));
// get two new lists
List<ProducerDTO> matching = classifiedElements.get(true);
List<ProducerDTO> nonMatching = classifiedElements.get(false);
// OR get non-matching elements to the existing list
producersProcedureActive = classifiedElements.get(false);
This way you effectively remove the filtered elements from the original list and add them to a new list.
Refer the 5.2. Collectors.partitioningBy section of this article.
Using LIKE will give you options for defining what the rest of the string should look like, but if the rule is just starts with 'NoHist_' it doesn't really matter.
You don't need to create a button. The facility exists by default.
Just right click on the arrow buttons on the bottom left hand corner of the Excel window. These are the arrow buttons which if you left click move left or right one worksheet.
If you right-click on these arrows Excel will pop up a dialogue with a list of worksheets from which you can click to set your chosen sheet active.
I know this Q is old, but why not use all DIVs instead of the SPANs? Then everything plays all happy together.
Example:
<div>
<div> content1(divs,p, spans, etc) </div>
<div> content2(divs,p, spans, etc) </div>
<div> content3(divs,p, spans, etc) </div>
</div>
<div>
<div> content4(divs,p, spans, etc) </div>
<div> content5(divs,p, spans, etc) </div>
<div> content6(divs,p, spans, etc) </div>
</div>
"Compiled in 64 bit" is not well defined in C++.
C++ sets only lower limits for sizes such as int, long and void *
. There is no guarantee that int is 64 bit even when compiled for a 64 bit platform. The model allows for e.g. 23 bit int
s and sizeof(int *) != sizeof(char *)
There are different programming models for 64 bit platforms.
Your best bet is a platform specific test. Your second best, portable decision must be more specific in what is 64 bit.
Assuming you are talking about the ActionEvent
class, then there is a big difference between the two methods.
getActionCommand()
gives you a String representing the action command. The value is component specific; for a JButton
you have the option to set the value with setActionCommand(String command)
but for a JTextField
if you don't set this, it will automatically give you the value of the text field. According to the javadoc this is for compatability with java.awt.TextField
.
getSource()
is specified by the EventObject
class that ActionEvent
is a child of (via java.awt.AWTEvent
). This gives you a reference to the object that the event came from.
Edit:
Here is a example. There are two fields, one has an action command explicitly set, the other doesn't. Type some text into each then press enter.
public class Events implements ActionListener {
private static JFrame frame;
public static void main(String[] args) {
frame = new JFrame("JTextField events");
frame.getContentPane().setLayout(new FlowLayout());
JTextField field1 = new JTextField(10);
field1.addActionListener(new Events());
frame.getContentPane().add(new JLabel("Field with no action command set"));
frame.getContentPane().add(field1);
JTextField field2 = new JTextField(10);
field2.addActionListener(new Events());
field2.setActionCommand("my action command");
frame.getContentPane().add(new JLabel("Field with an action command set"));
frame.getContentPane().add(field2);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(220, 150);
frame.setResizable(false);
frame.setVisible(true);
}
@Override
public void actionPerformed(ActionEvent evt) {
String cmd = evt.getActionCommand();
JOptionPane.showMessageDialog(frame, "Command: " + cmd);
}
}
You can cast a double to a decimal like this, without needing the M
literal suffix:
double dbl = 1.2345D;
decimal dec = (decimal) dbl;
You should use the M
when declaring a new literal decimal value:
decimal dec = 123.45M;
(Without the M
, 123.45 is treated as a double and will not compile.)
This is a fundamental understanding in Java, but can be a little tricky to new programmers. Do a little research on the difference between a static and instance method. The basic difference is the instance method do() is only accessible to a instance of the class foo.
You must instantiate (create an instance of) the class, creating an object, that you use to call the instance method.
I have included your example with a couple comments and example.
public class SomeName {
//this is a static method and cannot call an instance method without a object
public static void main(String[] args){
// can't do this from this static method, no object reference
// someMethod();
//create instance of object
SomeName thisObj = new SomeName();
//call instance method using object
thisObj.someMethod();
}
//instance method
public void someMethod(){
System.out.print("some message...");
}
}// end class SomeName

I am late but complete solution;: Example Class, Use Context like this :-
public class SingletonSampleClass {
// Your cute context
private Context context;
private static SingletonSampleClass instance;
// Pass as Constructor
private SingletonSampleClass(Context context) {
this.context = context;
}
public synchronized static SingletonSampleClass getInstance(Context context) {
if (instance == null) instance = new SingletonSampleClass(context);
return instance;
}
//At end, don't forgot to relase memory
public void onDestroy() {
if(context != null) {
context = null;
}
}
}
Warning (Memory Leaks)
How to solve this?
Option 1: Instead of passing activity context i.e. this to the singleton class, you can pass applicationContext().
Option 2: If you really have to use activity context, then when the activity is destroyed, ensure that the context you passed to the singleton class is set to null.
Hope it helps..????
I implemented the answer suggested by @user18490 but ran into two problems:
undefined
error mentioned by @krivarI developed the following class to get around the mentioned problems, and it works fine:
export class SScroll{
constructor(){
this.delay=501 //ms
this.duration=500 //ms
this.lastClick=0
}
lastClick
delay
duration
scrollTo=(destID)=>{
/* To prevent "bounce" */
/* https://stackoverflow.com/a/28610565/3405291 */
if(this.lastClick>=(Date.now()-this.delay)){return}
this.lastClick=Date.now()
const dest=document.getElementById(destID)
const to=dest.offsetTop
if(document.body.scrollTop==to){return}
const diff=to-document.body.scrollTop
const scrollStep=Math.PI / (this.duration/10)
let count=0
let currPos
const start=window.pageYOffset
const scrollInterval=setInterval(()=>{

count++
currPos=start+diff*(.5-.5*Math.cos(count*scrollStep))
document.body.scrollTop=currPos
}else{clearInterval(scrollInterval)}
},10)
}
}
There is a problem with Firefox as mentioned here. Therefore, to make it work on Firefox, I implemented the following code. It works fine on Chromium-based browsers and also Firefox.
export class SScroll{
constructor(){
this.delay=501 //ms
this.duration=500 //ms
this.lastClick=0
}
lastClick
delay
duration
scrollTo=(destID)=>{
/* To prevent "bounce" */
/* https://stackoverflow.com/a/28610565/3405291 */
if(this.lastClick>=(Date.now()-this.delay)){return}
this.lastClick=Date.now()
const dest=document.getElementById(destID)
const to=dest.offsetTop
if((document.body.scrollTop || document.documentElement.scrollTop || 0)==to){return}
const diff=to-(document.body.scrollTop || document.documentElement.scrollTop || 0)
const scrollStep=Math.PI / (this.duration/10)
let count=0
let currPos
const start=window.pageYOffset
const scrollInterval=setInterval(()=>{
if((document.body.scrollTop || document.documentElement.scrollTop || 0)!=to){
count++
currPos=start+diff*(.5-.5*Math.cos(count*scrollStep))
/* https://stackoverflow.com/q/28633221/3405291 */
/* To support both Chromium-based and Firefox */
document.body.scrollTop=currPos
document.documentElement.scrollTop=currPos
}else{clearInterval(scrollInterval)}
},10)
}
}
In your case It seems like the # will always be after teh # symbol so using CHARINDEX() with LTRIM() and RTRIM() would probably perform the best. But here is an interesting method of getting rid of ANY non digit. It utilizes a tally table and table of digits to limit which characters are accepted then XML technique to concatenate back to a single string without the non-numeric characters. The neat thing about this technique is it could be expanded to included ANY Allowed characters and strip out anything that is not allowed.
DECLARE @ExampleData AS TABLE (Col VARCHAR(100))
INSERT INTO @ExampleData (Col) VALUES ('AB ABCDE # 123'),('ABCDE# 123'),('AB: ABC# 123')
DECLARE @Digits AS TABLE (D CHAR(1))
INSERT INTO @Digits (D) VALUES ('0'),('1'),('2'),('3'),('4'),('5'),('6'),('7'),('8'),('9')
;WITH cteTally AS (
SELECT
I = ROW_NUMBER() OVER (ORDER BY (SELECT NULL))
FROM
@Digits d10
CROSS APPLY @Digits d100
--add more cross applies to cover longer fields this handles 100
)
SELECT *

@ExampleData e
OUTER APPLY (

400 Bad Request would now seem to be the best HTTP/1.1 status code for your use case.
At the time of your question (and my original answer), RFC 7231 was not a thing; at which point I objected to 400 Bad Request
because RFC 2616 said (with emphasis mine):
The request could not be understood by the server due to malformed syntax.
and the request you describe is syntactically valid JSON encased in syntactically valid HTTP, and thus the server has no issues with the syntax of the request.
However as pointed out by Lee Saferite in the comments, RFC 7231, which obsoletes RFC 2616, does not include that restriction:
The 400 (Bad Request) status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
However, prior to that re-wording (or if you want to quibble about RFC 7231 only being a proposed standard right now), 422 Unprocessable Entity
does not seem an incorrect HTTP status code for your use case, because as the introduction to RFC 4918 says:
While the status codes provided by HTTP/1.1 are sufficient to describe most error conditions encountered by WebDAV methods, there are some errors that do not fall neatly into the existing categories. This specification defines extra status codes developed for WebDAV methods (Section 11)
And the description of 422
says:
The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions.
(Note the reference to syntax; I suspect 7231 partly obsoletes 4918 too)
This sounds exactly like your situation, but just in case there was any doubt, it goes on to say:
For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.
(Replace "XML" with "JSON" and I think we can agree that's your situation)
Now, some will object that RFC 4918 is about "HTTP Extensions for Web Distributed Authoring and Versioning (WebDAV)" and that you (presumably) are doing nothing involving WebDAV so shouldn't use things from it.
Given the choice between using an error code in the original standard that explicitly doesn't cover the situation, and one from an extension that describes the situation exactly, I would choose the latter.
Furthermore, RFC 4918 Section 21.4 refers to the IANA Hypertext Transfer Protocol (HTTP) Status Code Registry, where 422 can be found.
I propose that it is totally reasonable for an HTTP client or server to use any status code from that registry, so long as they do so correctly.
But as of HTTP/1.1, RFC 7231 has traction, so just use 400 Bad Request
!
For integers and with Python 3:
def divround_down(value, step):
return value//step*step
def divround_up(value, step):
return (value+step-1)//step*step
Producing:
>>> [divround_down(x,5) for x in range(20)]
[0, 0, 0, 0, 0, 5, 5, 5, 5, 5, 10, 10, 10, 10, 10, 15, 15, 15, 15, 15]
>>> [divround_up(x,5) for x in range(20)]
[0, 5, 5, 5, 5, 5, 10, 10, 10, 10, 10, 15, 15, 15, 15, 15, 20, 20, 20, 20]
Believe or not, keytool does not provide such basic functionality like importing private key to keystore. You can try this workaround with merging PKSC12 file with private key to a keystore:
keytool -importkeystore \
-deststorepass storepassword \
-destkeypass keypassword \
-destkeystore my-keystore.jks \
-srckeystore cert-and-key.p12 \
-srcstoretype PKCS12 \
-srcstorepass p12password \
-alias 1
Or just use more user-friendly KeyMan from IBM for keystore handling instead of keytool.
If you don't want to roll your own, there is a function available in the pydoc
module that does exactly this:
from pydoc import locate
my_class = locate('my_package.my_module.MyClass')
The advantage of this approach over the others listed here is that locate
will find any python object at the provided dotted path, not just an object directly within a module. e.g. my_package.my_module.MyClass.attr
.
If you're curious what their recipe is, here's the function:
def locate(path, forceload=0):
"""Locate an object by name or dotted path, importing as necessary."""
parts = [part for part in split(path, '.') if part]
module, n = None, 0
while n < len(parts):
nextmodule = safeimport(join(parts[:n+1], '.'), forceload)
if nextmodule: module, n = nextmodule, n + 1
else: break
if module:
object = module
else:
object = __builtin__
for part in parts[n:]:
try:
object = getattr(object, part)
except AttributeError:
return None
return object
It relies on pydoc.safeimport
function. Here are the docs for that:
"""Import a module; handle errors; return None if the module isn't found.
If the module *is* found but an exception occurs, it's wrapped in an
ErrorDuringImport exception and reraised. Unlike __import__, if a
package path is specified, the module at the end of the path is returned,
not the package at the beginning. If the optional 'forceload' argument
is 1, we reload the module from disk (unless it's a dynamic extension)."""
You can also do it this way
private static string GetPaddingSequence(int padding)
{
StringBuilder SB = new StringBuilder();
for (int i = 0; i < padding; i++)
{
SB.Append("0");
}
return SB.ToString();
}
public static string FormatNumber(int number, int padding)
{
return number.ToString(GetPaddingSequence(padding));
}
Finally call the function FormatNumber
string x = FormatNumber(1,2);
Output will be 01 which is based on your padding parameter. Increasing it will increase the number of 0s
Updated Answer
jQuery changed the location of where events are stored in 1.8. Now you know why it is such a bad idea to mess around with internal APIs :)
The new internal API to access to events for a DOM object is available through the global jQuery object, and not tied to each instance, and it takes a DOM element as the first parameter, and a key ("events" for us) as the second parameter.
jQuery._data(<DOM element>, "events");
So here's the modified code for jQuery 1.8.
// [name] is the name of the event "click", "mouseover", ..
// same as you'd pass it to bind()
// [fn] is the handler function
$.fn.bindFirst = function(name, fn) {
// bind as you normally would
// don't want to miss out on any jQuery magic
this.on(name, fn);
// Thanks to a comment by @Martin, adding support for
// namespaced events too.
this.each(function() {
var handlers = $._data(this, 'events')[name.split('.')[0]];
// take out the handler we just inserted from the end
var handler = handlers.pop();
// move it at the beginning
handlers.splice(0, 0, handler);
});
};
And here's a playground.
Original Answer
As @Sean has discovered, jQuery exposes all event handlers through an element's data
interface. Specifically element.data('events')
. Using this you could always write a simple plugin whereby you could insert any event handler at a specific position.
Here's a simple plugin that does just that to insert a handler at the beginning of the list. You can easily extend this to insert an item at any given position. It's just array manipulation. But since I haven't seen jQuery's source and don't want to miss out on any jQuery magic from happening, I normally add the handler using bind
first, and then reshuffle the array.
// [name] is the name of the event "click", "mouseover", ..
// same as you'd pass it to bind()
// [fn] is the handler function
$.fn.bindFirst = function(name, fn) {
// bind as you normally would
// don't want to miss out on any jQuery magic
this.bind(name, fn);
// Thanks to a comment by @Martin, adding support for
// namespaced events too.
var handlers = this.data('events')[name.split('.')[0]];
// take out the handler we just inserted from the end
var handler = handlers.pop();
// move it at the beginning
handlers.splice(0, 0, handler);
};
So for example, for this markup it would work as (example here):
<div id="me">..</div>
$("#me").click(function() { alert("1"); });
$("#me").click(function() { alert("2"); });
$("#me").bindFirst('click', function() { alert("3"); });
$("#me").click(); // alerts - 3, then 1, then 2
However, since .data('events')
is not part of their public API as far as I know, an update to jQuery could break your code if the underlying representation of attached events changes from an array to something else, for example.
Disclaimer: Since anything is possible :), here's your solution, but I would still err on the side of refactoring your existing code, as just trying to remember the order in which these items were attached can soon get out of hand as you keep adding more and more of these ordered events.

List<Person> roster = ...;
Map<String, Person> map =
roster
.stream()
.collect(
Collectors.toMap(p -> p.getLast(), p -> p)
);
that would be the translation, but i havent run this or used the API. most likely you can substitute p -> p, for Function.identity(). and statically import toMap(...)
Some other ideas not mentioned yet:
switch(true){
case in_array($p, array('home', '')):
$current_home = 'current'; break;
case preg_match('/^users\.(online|location|featured|new|browse|search|staff)$/', $p):
$current_users = 'current'; break;
case 'forum' == $p:
$current_forum = 'current'; break;
}
Someone will probably complain about readability issues with #2, but I would have no problem inheriting code like that.
bringToFront()
is the right way, but, NOTE that you must call bringToFront()
and invalidate()
method on highest-level view (under your root view), for e.g.:
Your view's hierarchy is:
-RelativeLayout
|--LinearLayout1
|------Button1
|------Button2
|------Button3
|--ImageView
|--LinearLayout2
|------Button4
|------Button5
|------Button6
So, when you animate back your buttons (1->6), your buttons will under (below) the ImageView
. To bring it over (above) the ImageView
you must call bringToFront()
and invalidate()
method on your LinearLayout
s. Then it will work :)

If both arrays are in the correct order; where each item corresponds to its associated member identifier then you can simply use.
var merge = _.merge(arr1, arr2);
Which is the short version of:
var merge = _.chain(arr1).zip(arr2).map(function(item) {
return _.merge.apply(null, item);
}).value();
Or, if the data in the arrays is not in any particular order, you can look up the associated item by the member value.
var merge = _.map(arr1, function(item) {
return _.merge(item, _.find(arr2, { 'member' : item.member }));
});
You can easily convert this to a mixin. See the example below:
_.mixin({_x000D_
'mergeByKey' : function(arr1, arr2, key) {_x000D_
var criteria = {};_x000D_
criteria[key] = null;_x000D_
return _.map(arr1, function(item) {_x000D_
criteria[key] = item[key];_x000D_
return _.merge(item, _.find(arr2, criteria));_x000D_
});_x000D_
}_x000D_
});_x000D_

If you are trying to match the size as shown in Windows Explorer's detail view, this is the code you want:
[DllImport("shlwapi.dll", CharSet = CharSet.Unicode)]
private static extern long StrFormatKBSize(
long qdw,
[MarshalAs(UnmanagedType.LPTStr)] StringBuilder pszBuf,
int cchBuf);
public static string BytesToString(long byteCount)
{
var sb = new StringBuilder(32);
StrFormatKBSize(byteCount, sb, sb.Capacity);
return sb.ToString();
}
This will not only match Explorer exactly but will also provide the strings translated for you and match differences in Windows versions (for example in Win10, K = 1000 vs. previous versions K = 1024).

I use data.table's :=
operator to delete columns instantly regardless of the size of the table.
DT[, coltodelete := NULL]
or
DT[, c("col1","col20") := NULL]
or
DT[, (125:135) := NULL]
or
DT[, (variableHoldingNamesOrNumbers) := NULL]
Any solution using <-
or subset
will copy the whole table. data.table's :=
operator merely modifies the internal vector of pointers to the columns, in place. That operation is therefore (almost) instant.
Old one I made for my stuff...

var secondfromendchar = numberastext.Substring(numberastext.Length - 1);
secondfromendchar = numberastext.Remove(numberastext.Length - 1);
}
var suffix = "th";
var digit = int.Parse(endchar);
switch (digit){
case 3:
if(secondfromendchar != "1"){
suffix = "rd";
break;
}
case 2:
if(secondfromendchar != "1"){
suffix = "nd";
break;
}
case 1:
if(secondfromendchar != "1"){
suffix = "st";
break;
}
default:
suffix = "th";
break;
}
return number+suffix+" ";
} else {
return;
}
}
Old topic, but I was recently affected by this.
Using a class "row-fluid" instead of "row" worked fine for me but I'm not sure if it's fully supported going forward.
So after reading Why does the bootstrap .row has a default margin-left of -30px I just used the <div>
(without any row class) and it behaved exactly like <div class="row-fluid">
Both worked for me.
SELECT * FROM TABLE(SYSPROC.ENV_GET_INST_INFO());
or
SELECT * FROM SYSIBMADM.ENV_INST_INFO;
You can use margin-top: -50% to move the text all the way to the top of the div.
margin-top: -50%;

I experienced this soon after compiling and installing a shiny new GCC — version 8.1 — on RHEL 7. In the end, it ended up being a permissions problem; my root umask was the culprit. I eventually found cc1
hiding in /usr/local/libexec
:
[root@nacelle gdb-8.1]# ls -l /usr/local/libexec/gcc/x86_64-pc-linux-gnu/8.1.0/ | grep cc1
-rwxr-xr-x 1 root root 196481344 Jul 2 13:53 cc1
However, the permissions on the directories leading there didn't allow my standard user account:
[root@nacelle gdb-8.1]# ls -l /usr/local/libexec/
total 4
drwxr-x--- 3 root root 4096 Jul 2 13:53 gcc
[root@nacelle gdb-8.1]# ls -l /usr/local/libexec/gcc/
total 4
drwxr-x--- 3 root root 4096 Jul 2 13:53 x86_64-pc-linux-gnu
[root@nacelle gdb-8.1]# ls -l /usr/local/libexec/gcc/x86_64-pc-linux-gnu/
total 4
drwxr-x--- 4 root root 4096 Jul 2 13:53 8.1.0
A quick recursive chmod
to add world read/execute permissions fixed it right up:
[root@nacelle 8.1.0]# cd /usr/local/libexec
[root@nacelle lib]# ls -l | grep gcc
drwxr-x--- 3 root root 4096 Jul 2 13:53 gcc
[root@nacelle lib]# chmod -R o+rx gcc
[root@nacelle lib]# ls -l | grep gcc
drwxr-xr-x 3 root root 4096 Jul 2 13:53 gcc
And now gcc
can find cc1
when I ask it to compile something!
jQuery 3
As of jQuery 3, removeAttr
does not set the corresponding property to false
anymore:
Prior to jQuery 3.0, using
.removeAttr()
on a boolean attribute such aschecked
,selected
, orreadonly
would also set the corresponding named property tofalse
. This behavior was required for ancient versions of Internet Explorer but is not correct for modern browsers because the attribute represents the initial value and the property represents the current (dynamic) value.It is almost always a mistake to use
.removeAttr( "checked" )
on a DOM element. The only time it might be useful is if the DOM is later going to be serialized back to an HTML string. In all other cases,.prop( "checked", false )
should be used instead.
Hence only .prop('checked',false)
is correct way when using this version.
Original answer (from 2011):
For attributes which have underlying boolean properties (of which checked
is one), removeAttr
automatically sets the underlying property to false
. (Note that this is among the backwards-compatibility "fixes" added in jQuery 1.6.1).
So, either will work... but the second example you gave (using prop
) is the more correct of the two. If your goal is to uncheck the checkbox, you really do want to affect the property, not the attribute, and there's no need to go through removeAttr
to do that.
You can figure out the dimensions of the screen dynamically
Display mDisplay= activity.getWindowManager().getDefaultDisplay();
int width= mDisplay.getWidth();
int Height= mDisplay.getHeight();
The layout can be set using the width and the height obtained using this method.
Bill Venners: In your blog post entitled "Why REST Failed," you said that we need all four HTTP verbs—GET, POST, PUT, and DELETE— and lamented that browser vendors only GET and POST." Why do we need all four verbs? Why aren't GET and POST enough?
Elliotte Rusty Harold: There are four basic methods in HTTP: GET, POST, PUT, and DELETE. GET is used most of the time. It is used for anything that's safe, that doesn't cause any side effects. GET is able to be bookmarked, cached, linked to, passed through a proxy server. It is a very powerful operation, a very useful operation.
POST by contrast is perhaps the most powerful operation. It can do anything. There are no limits as to what can happen, and as a result, you have to be very careful with it. You don't bookmark it. You don't cache it. You don't pre-fetch it. You don't do anything with a POST without asking the user. Do you want to do this? If the user presses the button, you can POST some content. But you're not going to look at all the buttons on a page, and start randomly pressing them. By contrast browsers might look at all the links on the page and pre-fetch them, or pre-fetch the ones they think are most likely to be followed next. And in fact some browsers and Firefox extensions and various other tools have tried to do that at one point or another.
PUT and DELETE are in the middle between GET and POST. The difference between PUT or DELETE and POST is that PUT and DELETE are *idempotent, whereas POST is not. PUT and DELETE can be repeated if necessary. Let's say you're trying to upload a new page to a site. Say you want to create a new page at http://www.example.com/foo.html, so you type your content and you PUT it at that URL. The server creates that page at that URL that you supply. Now, let's suppose for some reason your network connection goes down. You aren't sure, did the request get through or not? Maybe the network is slow. Maybe there was a proxy server problem. So it's perfectly OK to try it again, or again—as many times as you like. Because PUTTING the same document to the same URL ten times won't be any different than putting it once. The same is true for DELETE. You can DELETE something ten times, and that's the same as deleting it once.
By contrast, POST, may cause something different to happen each time. Imagine you are checking out of an online store by pressing the buy button. If you send that POST request again, you could end up buying everything in your cart a second time. If you send it again, you've bought it a third time. That's why browsers have to be very careful about repeating POST operations without explicit user consent, because POST may cause two things to happen if you do it twice, three things if you do it three times. With PUT and DELETE, there's a big difference between zero requests and one, but there's no difference between one request and ten.

Update:
Idempotent methods An idempotent HTTP method is a HTTP method that can be called many times without different outcomes. It would not matter if the method is called only once, or ten times over. The result should be the same. Again, this only applies to the result, not the resource itself. This still can be manipulated (like an update-timestamp, provided this information is not shared in the (current) resource representation.
Consider the following examples:
a = 4;
a++;
The first example is idempotent: no matter how many times we execute this statement, a will always be 4. The second example is not idempotent. Executing this 10 times will result in a different outcome as when running 5 times. Since both examples are changing the value of a, both are non-safe methods.

For anyone using docker, I ran into this issue, and resolved it by using my own Dockerfile instead of the php:fpm image:
FROM php:fpm
RUN docker-php-ext-install mysqli
The other (and perhaps simplest) option for acheiving a clearfix is to use overflow:hidden;
on the containing element. For example
.parent {_x000D_
background: red;_x000D_
overflow: hidden;_x000D_
}_x000D_
.segment-a {_x000D_
float: left;_x000D_
}_x000D_
.segment-b {_x000D_
float: right;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div class="segment-a">_x000D_
Float left_x000D_
</div>_x000D_
<div class="segment-b">_x000D_
Float right_x000D_
</div>_x000D_
</div>
_x000D_
Of course this can only be used in instances where you never wish the content to overflow.
This can be done neatly in one line with:
df = df.drop(df.filter(regex='Test').columns, axis=1)

Use the below statement to delete any files:
FileUtils.forceDelete(FilePath);
Note: Use exception handling
codes if you want to use.
You can use this syntax:
if myItem in list:
# do something
Also, inverse operator:
if myItem not in list:
# do something
It's work fine for lists, tuples, sets and dicts (check keys).
Note that this is an O(n) operation in lists and tuples, but an O(1) operation in sets and dicts.
These methods are in ObjectNode
: the division is such that most read operations are included in JsonNode
, but mutations in ObjectNode
and ArrayNode
.
Note that you can just change first line to be:
ObjectNode jNode = mapper.createObjectNode();
// version ObjectMapper has should return ObjectNode type
or
ObjectNode jNode = (ObjectNode) objectCodec.createObjectNode();
// ObjectCodec is in core part, must be of type JsonNode so need cast
A BufferedReader constructor takes a reader as argument, not an InputStream. You should first create a Reader from your stream, like so:
Reader reader = new InputStreamReader(is);
BufferedReader br = new BufferedReader(reader);
Preferrably, you also provide a Charset or character encoding name to the StreamReader constructor. Since a stream just provides bytes, converting these to text means the encoding must be known. If you don't specify it, the system default is assumed.
Here's the strsplit
solution if s
is a vector:
> s <- c("TGAS_1121", "MGAS_1432")
> s1 <- sapply(strsplit(s, split='_', fixed=TRUE), function(x) (x[2]))
> s1
[1] "1121" "1432"
If you only need to look at the existing disks, this one will suffice:

Create a vectorized method
def calc_xb_minus_xa(df):
time_dict = {
'<Minute>': 'm',
'<Hour>': 'h',
'<Day>': 'D',
'<Week>': 'W',
'<Month>': 'M',
'<Year>': 'Y'
}
time_delta = df.at[df.index[0], 'end_time'] - df.at[df.index[0], 'open_time']
offset_base_name = str(to_offset(time_delta).base)
time_term = time_dict.get(offset_base_name)
result = (df.end_time - df.open_time) / np.timedelta64(1, time_term)
return result
Then in your df do:
df['x'] = calc_xb_minus_xa(df)
This will work for minutes, hours, days, weeks, month and Year. open_time and end_time need to change according your df
What worked for me was copping the .settings/ directory from another project.
The solution in simple, but not immediatly.
If you want use this instruction, you must make one change to the db:
ALTER USER user SET search_path to 'name_of_schema';
after these changes "INSERT" will work correctly.
What about this shorter, more transparent, yet more intuitive with array_walk
$attributes = array(
'data-href' => 'http://example.com',
'data-width' => '300',
'data-height' => '250',
'data-type' => 'cover',
);
$args = "";
array_walk(
$attributes,
function ($item, $key) use (&$args) {
$args .= $key ." = '" . $item . "' ";
}
);
// output: 'data-href="http://example.com" data-width="300" data-height="250" data-type="cover"
For #4, the closest thing to starting java with a jar file for your app is a new feature in Python 2.6, executable zip files and directories.
python myapp.zip
Where myapp.zip is a zip containing a __main__.py
file which is executed as the script file to be executed. Your package dependencies can also be included in the file:
__main__.py
mypackage/__init__.py
mypackage/someliblibfile.py
You can also execute an egg, but the incantation is not as nice:
# Bourn Shell and derivatives (Linux/OSX/Unix)
PYTHONPATH=myapp.egg python -m myapp
rem Windows
set PYTHONPATH=myapp.egg
python -m myapp
This puts the myapp.egg on the Python path and uses the -m argument to run a module. Your myapp.egg will likely look something like:
myapp/__init__.py
myapp/somelibfile.py
And python will run __init__.py
(you should check that __file__=='__main__'
in your app for command line use).
Egg files are just zip files so you might be able to add __main__.py
to your egg with a zip tool and make it executable in python 2.6 and run it like python myapp.egg
instead of the above incantation where the PYTHONPATH environment variable is set.
More information on executable zip files including how to make them directly executable with a shebang can be found on Michael Foord's blog post on the subject.
What has worked for me (may be a newer feature of Maven) is merely doing wildcards in the exclusion element.
I have a multi-module project that contains an "app" module that is referenced in two WAR-packaged modules. One of those WAR-packaged modules really only needs the domain classes (and I haven't separated them out of the app module yet). I found this to work:
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>app</artifactId>
<version>${project.version}</version>
<exclusions>
<exclusion>
<groupId>*</groupId>
<artifactId>*</artifactId>
</exclusion>
</exclusions>
</dependency>
The wildcard on both groupId and artifactId exclude all dependencies that normally would propagate through to the module using this dependency.
Use nsIJSON if this is for a FF extension:
var req = new XMLHttpRequest;
req.overrideMimeType("application/json");
req.open('GET', BITLY_CREATE_API + encodeURIComponent(url) + BITLY_API_LOGIN, true);
var target = this;
req.onload = function() {target.parseJSON(req, url)};
req.send(null);
parseJSON: function(req, url) {
if (req.status == 200) {
var jsonResponse = Components.classes["@mozilla.org/dom/json;1"]
.createInstance(Components.interfaces.nsIJSON.decode(req.responseText);
var bitlyUrl = jsonResponse.results[url].shortUrl;
}
For a webpage, just use JSON.parse
instead of Components.classes["@mozilla.org/dom/json;1"].createInstance(Components.interfaces.nsIJSON.decode
Here is simple way using Top object.
eg: If absolute element size is 60px.
.absolute-element {
position:absolute;
height:60px;
top: calc(50% - 60px);
}
If you are running the program with python, try running it with python3.
Previous poster is right. You cannot return multiple values from a C# method. However, you do have a couple of options:
The pros and cons here are often hard to figure out. If you return a structure, make sure it's small because structs are value type and passed on the stack. If you return an instance of a class, there are some design patterns here that you might want to use to avoid causing problems - members of classes can be modified because C# passes objects by reference (you don't have ByVal like you did in VB).
Finally you can use output parameters but I would limit the use of this to scenarios when you only have a couple (like 3 or less) of parameters - otherwise things get ugly and hard to maintain. Also, the use of output parameters can be an inhibitor to agility because your method signature will have to change every time you need to add something to the return value whereas returning a struct or class instance you can add members without modifying the method signature.
From an architectural standpoint I would recommend against using key-value pairs or dictionaries. I find this style of coding requires "secret knowledge" in code that consumes the method. It must know ahead of time what the keys are going to be and what the values mean and if the developer working on the internal implementation changes the way the dictionary or KVP is created, it could easily create a failure cascade throughout the entire application.
This problem occurs when you copy paste class and didn't change package name. Means Package name are different. Build has no problem to build but its problem to install.
If you want to link, say, libapplejuice statically, but not, say, liborangejuice, you can link like this:
gcc object1.o object2.o -Wl,-Bstatic -lapplejuice -Wl,-Bdynamic -lorangejuice -o binary
There's a caveat -- if liborangejuice
uses libapplejuice
, then libapplejuice
will be dynamically linked too.
You'll have to link liborangejuice
statically alongside with libapplejuice
to get libapplejuice
static.
And don't forget to keep -Wl,-Bdynamic
else you'll end up linking everything static, including libc
(which isn't a good thing to do).
Recursively search for a string in a directory tree:
findstr /S /C:"string literal" *.*
You can also use regular expressions:
findstr /S /R "^ERROR" *.log
Recursive file search:
dir /S myfile.txt
Without mod_expires it will be harder to set expiration headers on your files. For anything generated you can certainly set some default headers on the answer, doing the job of mod_expires like that:
<?php header('Expires: '.gmdate('D, d M Y H:i:s \G\M\T', time() + 3600)); ?>
(taken from: Stack Overflow answer from @brianegge, where the mod_expires solution is also explained)
Now this won't work for static files, like your javascript files. As for static files there is only apache (without any expiration module) between the browser and the source file.
To prevent caching of javascript files, which is done on your browser, you can use a random token at the end of the js url, something like ?rd=45642111
, so the url looks like:
<script type="texte/javascript" src="my/url/myjs.js?rd=4221159546">
If this url on the page is generated by a PHP file you can simply add the random part with PHP. This way of randomizing url by simply appending random query string parameters is the base thing upôn no-cache setting of ajax jQuery request for example. The browser will never consider 2 url having different query strings to be the same, and will never use the cached version.
EDIT
Note that you should alos test mod_headers. If you have mod_headers you can maybe set the Expires headers directly with the Header keyword.
One way is to add the item(s) to be deleted to a new list. Then go through and delete those items.
All these answers seem a bit complicated. I would just subtract 0.5 from your number and use toFixed().
In SQL without SELECT
you cannot result anything. Instead of IF-ELSE
block I prefer to use CASE
statement for this
SELECT CASE
WHEN EXISTS (SELECT 1
FROM tblGLUserAccess
WHERE GLUserName = 'xxxxxxxx') THEN 1
ELSE 2
END
If you want to import a specific function or class from a module, you can do this:
import importlib
import sys
importlib.reload(sys.modules['my_module'])
from my_module import my_function
Try using this:-
mkdir -p dir;
NOTE:- This will also create any intermediate directories that don't exist; for instance,
Check out mkdir -p
or try this:-
if [[ ! -e $dir ]]; then
mkdir $dir
elif [[ ! -d $dir ]]; then
echo "$Message" 1>&2
fi
If you are using dataset to bind in a Grid, you can add the row after you fill in the sql data adapter:
adapter.Fill(ds);
ds.Tables(0).Rows.Add();

I'm not using it here because the current method covers my needs, but if someday it's needed
to extend or improve this module, then may want to investigate the WMI tools available.

Refer to the self.supported_types keys for the currently supported 'Performance Objects'
To add logging support for other data you can derive the necessary data from perfmon:
---------
perfmon can be run from windows 'run' menu by entering 'perfmon' and enter.
Clicking on the '+' will open the 'add counters' menu,
From the 'Add Counters' dialog, the 'Performance object' is the self.support_types key.
--> Where spaces are removed and symbols are entered as text (Ex. # == Number, % == Percent)
For the items you wish to log add the proper attribute name in the list in the self.supported_types dictionary,
keyed by the 'Performance Object' name as mentioned above.

+1 on S.Lott's suggestion of a named container class.
For Python 2.6 and up, a named tuple provides a useful way of easily creating these container classes, and the results are "lightweight and require no more memory than regular tuples".
I tried this in Python 3 , seems to work fine .
a, b = map(int,input().split())
print(a)
print(b)
Input : 3 44
Output :
3
44
To go one step further, I assume you want to do something with these dtypes.
df.dtypes.to_dict()
comes in handy.
my_type = 'float64' #<---
dtypes = dataframe.dtypes.to_dict()
for col_nam, typ in dtypes.items():
if (typ != my_type): #<---
raise ValueError(f"Yikes - `dataframe['{col_name}'].dtype == {typ}` not {my_type}")
You'll find that Pandas did a really good job comparing NumPy classes and user-provided strings. For example: even things like 'double' == dataframe['col_name'].dtype
will succeed when .dtype==np.float64
.
Looking at the "effective POM" will probably help too. For instance, if you wanted to know what the path is for ${project.build.sourceDirectory}
you would find the related XML in the effective POM, such as:
<project>
<build>
<sourceDirectory>/my/path</sourceDirectory>
Also helpful - you can do a real time evaluation of properties via the command line execution of mvn help:evaluate
while in the same dir as the POM.

The != operator most certainly does exist! It is an alias for the standard <>
operator.
Perhaps your fields are not actually empty strings, but instead NULL
?
To compare to NULL
you can use IS NULL
or IS NOT NULL
or the null safe equals operator <=>
.
Since you're dealing with static content...

In ES6:
const ID_LENGTH = 36
const START_LETTERS_ASCII = 97 // Use 64 for uppercase
const ALPHABET_LENGTH = 26
const uniqueID = () => [...new Array(ID_LENGTH)]
.map(() => String.fromCharCode(START_LETTERS_ASCII + Math.random() * ALPHABET_LENGTH))
.join('')
Example:

> "bxppcnanpuxzpyewttifptbklkurvvetigra"
It depends on the output you expect.
A cross join matches all rows in one table to all rows in another table. An inner join matches on a field or fields. If you have one table with 10 rows and another with 10 rows then the two joins will behave differently.
The cross join will have 100 rows returned and they won't be related, just what is called a Cartesian product. The inner join will match records to each other. Assuming one has a primary key and that is a foreign key in the other you would get 10 rows returned.
A cross join has limited general utility, but exists for completeness and describes the result of joining tables with no relations added to the query. You might use a cross join to make lists of combinations of words or something similar. An inner join on the other hand is the most common join.
Here's a complete read, update and write example.
Input file, test.ini
[section_a]
string_val = hello
bool_val = false
int_val = 11
pi_val = 3.14

try:
from configparser import ConfigParser
except ImportError:
from ConfigParser import ConfigParser # ver. < 3.0
# instantiate
config = ConfigParser()
# parse existing file
config.read('test.ini')
# read values from a section
string_val = config.get('section_a', 'string_val')
bool_val = config.getboolean('section_a', 'bool_val')
int_val = config.getint('section_a', 'int_val')
float_val = config.getfloat('section_a', 'pi_val')
# update existing value
config.set('section_a', 'string_val', 'world')
# add a new section and some values

config.set('section_b', 'not_found_val', '404')
# save to a file
with open('test_update.ini', 'w') as configfile:
config.write(configfile)
Output file, test_update.ini

You don't need to call $.toJSON
and add traditional = true
data: { sendInfo: array },
traditional: true
would do.
You need to return a view which has a friendly error message to the user
catch (Exception ex)
{
// to do :log error
return View("Error");
}
You should not be showing the internal details of your exception(like exception stacktrace etc) to the user. You should be logging the relevant information to your error log so that you can go through it and fix the issue.
If your request is an ajax request, You may return a JSON response with a proper status flag which client can evaluate and do further actions
[HttpPost]
public ActionResult Create(CustomerVM model)
{
try
{
//save customer
return Json(new { status="success",message="customer created"});
}
catch(Exception ex)
{
//to do: log error
return Json(new { status="error",message="error creating customer"});
}
}
If you want to show the error in the form user submitted, You may use ModelState.AddModelError
method along with the Html helper methods like Html.ValidationSummary
etc to show the error to the user in the form he submitted.
I'm using Walter's approach from above (see: https://stackoverflow.com/a/14246240/3076102)
I mix in a solution I found here https://stackoverflow.com/a/7967670 to properly show Objects.
This means the trap function becomes:
function trap(){
if(debugging){
// create an Array from the arguments Object
var args = Array.prototype.slice.call(arguments);
// console.raw captures the raw args, without converting toString
console.raw.push(args);
var index;
for (index = 0; index < args.length; ++index) {
//fix for objects
if(typeof args[index] === 'object'){
args[index] = JSON.stringify(args[index],null,'\t').replace(/\n/g,'<br>').replace(/\t/g,' ');
}
}
var message = args.join(' ');
console.messages.push(message);
// instead of a fallback function we use the next few lines to output logs
// at the bottom of the page with jQuery
if($){
if($('#_console_log').length == 0) $('body').append($('<div />').attr('id', '_console_log'));
$('#_console_log').append(message).append($('<br />'));
}
}
}
I hope this is helpful:-)
As far I know, every concatenation implies a memory reallocation. So the problem is not the operator used to do it, the solution is to reduce the number of concatenations. For example do the concatenations outside of the iteration structures when you can.
Sometimes it may occur, if there is any database connection in your code but you did not start the database server yet.
Im my case i have some piece of code to connect with mongodb

If you're using cygwin, the syntax is slightly different for the basename command.
find . -name "*.zip" | while read filename; do unzip -o -d "`basename "$filename" .zip`" "$filename"; done;
To fix this error on Centos 7:
Install PHP extension:
sudo yum install php-xml
Restart your web server. In my case it's php-fpm:
services php-fpm restart

ABI
- Application Binary Interface
is about a machine code communication in runtime between two binary parts like - application, library, OS... ABI
describes how objects are saved in memory, how functions are called(calling convention
), mangling...
A good example of API and ABI is iOS ecosystem with Swift language.
Application layer
- When you create an application using different languages. For example you can create application using Swift
and Objective-C
[Mixing Swift and Objective-C]
Application - OS layer
- runtime - Swift runtime
and standard libraries
are parts of OS and they should not be included into each bundle(e.g. app, framework). It is the same as like Objective-C uses
Library layer
- Module Stability
case - compile time - you will be able to import a framework which was built with another version of Swift's compiler. It means that it is safety to create a closed-source(pre-build) binary which will be consumed by a different version of compiler( .swiftinterface
is used with .swiftmodule
) and you will not get
Module compiled with _ cannot be imported by the _ compiler
Library layer
- Library Evolution
case
Don't forgot to use important browsers specific attributes:

After i iterations the first i elements are ordered.
In each iteration the next element is bubbled through the sorted section until it reaches the right spot:
sorted | unsorted
1 3 5 8 | 4 6 7 9 2
1 3 4 5 8 | 6 7 9 2
The 4 is bubbled into the sorted section
Pseudocode:
for i in 1 to n
for j in i downto 2
if array[j - 1] > array[j]
swap(array[j - 1], array[j])
else
break
After i iterations the last i elements are the biggest, and ordered.
In each iteration, sift through the unsorted section to find the maximum.
unsorted | biggest
3 1 5 4 2 | 6 7 8 9
1 3 4 2 | 5 6 7 8 9
The 5 is bubbled out of the unsorted section
Pseudocode:
for i in 1 to n
for j in 1 to n - i
if array[j] > array[j + 1]
swap(array[j], array[j + 1])
Note that typical implementations terminate early if no swaps are made during one of the iterations of the outer loop (since that means the array is sorted).
In insertion sort elements are bubbled into the sorted section, while in bubble sort the maximums are bubbled out of the unsorted section.
To add the latest solution for 2021...
I found that the project nanoid provides unique string ids that can be used as key while also being fast and very small.
After installing using npm install nanoid
, use as follows:
import { nanoid } from 'nanoid';
// Have the id associated with the data.
const todos = [{id: nanoid(), text: 'first todo'}];
// Then later, it can be rendered using a stable id as the key.
const todoItems = todos.map((todo) =>
<li key={todo.id}>
{todo.text}
</li>
)
Here is a solution to get the max value in about 99% of runs (change the 0.01 to get a better result):
public static double getMax(double[] vals){
final double[] max = {Double.NEGATIVE_INFINITY};
IntStream.of(new Random().ints((int) Math.ceil(Math.log(0.01) / Math.log(1.0 - (1.0/vals.length))),0,vals.length).toArray())
.forEach(r -> max[0] = (max[0] < vals[r])? vals[r]: max[0]);
return max[0];
}
(Not completely serious)
cascade = { CascadeType.ALL }, fetch = FetchType.LAZY
you can keep your withdraw and deposit methods static if you want however you'd have to write it like the code below. sb = starting balance and eB = ending balance.
Account account = new Account(1122, 20000, 4.5);
double sB = Account.withdraw(account.getBalance(), 2500);
double eB = Account.deposit(sB, 3000);
System.out.println("Balance is " + eB);
System.out.println("Monthly interest is " + (account.getAnnualInterestRate()/12));
account.setDateCreated(new Date());
System.out.println("The account was created " + account.getDateCreated());
Any input from a client are ways to be vulnerable. Including all forms and the query string. This includes all HTTP verbs.

Is it too late to answer. I would say, its better to go by Libraries like ClassPathScanningCandidateComponentProvider or like Scannotations
But even after somebody wants to try some hands on it with classLoader, I have written some on my own to print the annotations from classes in a package:
public class ElementScanner {
public void scanElements(){
try {
//Get the package name from configuration file
String packageName = readConfig();
//Load the classLoader which loads this class.
ClassLoader classLoader = getClass().getClassLoader();
//Change the package structure to directory structure
String packagePath = packageName.replace('.', '/');
URL urls = classLoader.getResource(packagePath);
//Get all the class files in the specified URL Path.
File folder = new File(urls.getPath());
File[] classes = folder.listFiles();
int size = classes.length;
List<Class<?>> classList = new ArrayList<Class<?>>();
for(int i=0;i<size;i++){
int index = classes[i].getName().indexOf(".");
String className = classes[i].getName().substring(0, index);
String classNamePath = packageName+"."+className;
Class<?> repoClass;
repoClass = Class.forName(classNamePath);
Annotation[] annotations = repoClass.getAnnotations();
for(int j =0;j<annotations.length;j++){
System.out.println("Annotation in class "+repoClass.getName()+ " is "+annotations[j].annotationType().getName());
}
classList.add(repoClass);
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
/**
* Unmarshall the configuration file
* @return
*/
public String readConfig(){
try{
URL url = getClass().getClassLoader().getResource("WEB-INF/config.xml");
JAXBContext jContext = JAXBContext.newInstance(RepositoryConfig.class);
Unmarshaller um = jContext.createUnmarshaller();
RepositoryConfig rc = (RepositoryConfig) um.unmarshal(new File(url.getFile()));
return rc.getRepository().getPackageName();
}catch(Exception e){
e.printStackTrace();
}
return null;
}
}
And in config File, you put the package name and unmarshall it to a class .
So many answers to such a seemingly simple question. Just to shake things up a little bit here is my solution to this problem.
Creating a Mutex can be troublesome because the JIT-er only sees you using it for a small portion of your code and wants to mark it as ready for garbage collection. It pretty much wants to out-smart you thinking you are not going to be using that Mutex for that long. In reality you want to hang onto this Mutex for as long as your application is running. The best way to tell the garbage collector to leave you Mutex alone is to tell it to keep it alive though out the different generations of garage collection. Example:
var m = new Mutex(...);
...
GC.KeepAlive(m);
I lifted the idea from this page: http://www.ai.uga.edu/~mc/SingleInstance.html
.cmd and .bat file execution is different because in a .cmd errorlevel variable it can change on a command that is affected by command extensions. That's about it really.
My program seems to suffer from linear access to dictionaries, its run-time grows exponentially even though the algorithm is quadratic.
I use a dictionary to memoize values. That seems to be a bottleneck.
This is evidence of a bug in your memoization method.
string mypath = @"..\folder1\folder2\folder2";
string[] directories = mypath.Split(Path.DirectorySeparatorChar);
Edit: This returns each individual folder in the directories array. You can get the number of folders returned like this:
int folderCount = directories.Length;
response.setContentType("text/json");
//create the JSON string, I suggest using some framework.
String your_string;
out.write(your_string.getBytes("UTF-8"));
For me, on Android Studio 4.1, what did the trick was good ole File > Invalidate Cache & Restart
No more Fatal Signals after that. I'm sure it had something to do with the profiler, but can't be certain. I just know restarting AS stopped the crashes on my emulator.

if this code does not work even under document ready, most probable you assigned a return false;
somewhere in your js file to that button, if it is button try to change it to a ,span, anchor or div and test if it is working.
$(document).on("click","#test-element",function() {
alert("click bound to document listening for #test-element");

If you use the track by
option, the value
attribute is correctly written, e.g.:
<div ng-init="a = [{label: 'one', value: 15}, {label: 'two', value: 20}]">
<select ng-model="foo" ng-options="x for x in a track by x.value"/>
</div>
produces:
<select>
<option value="" selected="selected"></option>
<option value="15">one</option>
<option value="20">two</option>

Also:
func getTime() -> (hour: Int, minute: Int,second: Int) {
let hour = 1
let minute = 2
let second = 3
return ( hour, minute, second)
}
Then it's invoked as:
let time = getTime()
print("hour: \(time.hour), minute: \(time.minute), second: \(time.second)")
This is the standard way how to use it in the book The Swift Programming Language written by Apple.
or just like:
let time = getTime()
print("hour: \(time.0), minute: \(time.1), second: \(time.2)")
it's the same but less clearly.
There is no solution for this within the .net framework.

Although that's not what your question title asks =)
If you wish to authenticate the users against windows system users [created by Administrator] then in that case you will go for Windows Authentication in your Application.
But in case you want to authenticate the users against set of users available in your application database, then in that case you will want to go for SQL Authentication.
Precisely if your application is an ASP.NET web-app, then you can use standard Login controls which depend on Providers like SqlMembershipProvider, SqlProfileProvider. You can configure your login controls and your application whether it should authenticate against windows users or app-database users. In the first case it will be called Windows Authentication and the later will be known as Sql Authentication.

This method works for me. It's checking if the person has had their birthday this year and subtracts one year otherwise.
// date is the moment you're calculating the age of
var now = moment().unix();
var then = date.unix();
var diff = (now - then) / (60 * 60 * 24 * 365);
var years = Math.floor(diff);
Edit: First version didn't quite work perfectly. The updated one should
Encountered this too also. Here's what I did.
On my LoginActivity, inside my AsyncTask, I have the following:
CookieStoreHelper.cookieStore = new BasicCookieStore();
BasicHttpContext localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.COOKIE_STORE, CookieStoreHelper.cookieStore);
HttpResponse postResponse = client.execute(httpPost,localContext);
CookieStoreHelper.sessionCookie = CookieStoreHelper.cookieStore.getCookies();
//WHERE CookieStoreHelper.sessionCookie is another class containing the variable sessionCookie defined as List cookies; and cookieStore define as BasicCookieStore cookieStore;
Then on my Fragment, where my WebView is located i have the following:
//DECLARE LIST OF COOKIE
List<Cookie> sessionCookie;
inside my method or just before you are setting the WebViewClient()
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
sessionCookie = CookieStoreHelper.cookieStore.getCookies();
CookieSyncManager.createInstance(webView.getContext());
CookieSyncManager.getInstance().startSync();
CookieManager cookieManager = CookieManager.getInstance();
CookieManager.getInstance().setAcceptCookie(true);
if (sessionCookie != null) {
for(Cookie c: sessionCookie){
cookieManager.setCookie(CookieStoreHelper.DOMAIN, c.getName() + "=" + c.getValue());
}
CookieSyncManager.getInstance().sync();
}
webView.setWebViewClient(new WebViewClient() {
//AND SO ON, YOUR CODE
}
Quick Tip: Have firebug installed on firefox or use developer console on chrome and test first your webpage, capture the Cookie and check the domain so you can store it somewhere and be sure that you are correctly setting the right domain.
Edit: edited CookieStoreHelper.cookies to CookieStoreHelper.sessionCookie
Using dplyr
:
require(dplyr)
df <- data.frame(A = c(1, 1, 2, 3, 3), B = c(2, 3, 3, 5, 6))
df %>% group_by(A) %>% summarise(B = sum(B))
## Source: local data frame [3 x 2]
##
## A B
## 1 1 5
## 2 2 3
## 3 3 11
With sqldf
:
library(sqldf)
sqldf('SELECT A, SUM(B) AS B FROM df GROUP BY A')
None of these options show up for me. The way to paste data from Excel is as follows:
Add an extra column to the left of your spreadsheet data (if you don't have row numbers showing in PL/SQL Developer you may not have to have an extra empty column to the left).
Copy the rows of data from your spreadsheet including the empty column.
In PL/SQL Developer, open your table in edit mode. You can right-click the table name in the object browser and select Edit Data or write your own select statement that includes the rowid and click the lock icon. Be sure your columns are ordered the same as in your spreadsheet.
Here's the part that took me forever to figure out: click on the left side of the first empty row to highlight it. It will not work if you don't have the first empty row highlighted.
Paste as usual using Ctrl+V or right-click Paste.
I couldn't find this info anywhere when I needed it, so I wanted to be sure to post it.
To convert a string to a number, subtract 0. To convert a number to a string, add "" (the empty string).
5 + 1 will give you 6
(5 + "") + 1 will give you "51"
("5" - 0) + 1 will give you 6
Just to give an option, writing a dictionary to csv file could also be done with the pandas package. With the given example it could be something like this:
mydict = {'key1': 'a', 'key2': 'b', 'key3': 'c'}
import pandas as pd
(pd.DataFrame.from_dict(data=mydict, orient='index')
.to_csv('dict_file.csv', header=False))
The main thing to take into account is to set the 'orient' parameter to 'index' inside the from_dict method. This lets you choose if you want to write each dictionary key in a new row.
Additionaly, inside the to_csv method the header parameter is set to False just to have only the dictionary elements without annoying rows. You can always set column and index names inside the to_csv method.
Your output would look like this:
key1,a
key2,b
key3,c
If instead you want the keys to be the column's names, just use the default 'orient' parameter that is 'columns', as you could check in the documentation links.
If you are providing mappings like this:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Configurations.Add(new ClassificationMap());
modelBuilder.Configurations.Add(new CompanyMap());
modelBuilder.Configurations.Add(new GroupMap());
....
}
Remember to add the map for BaseCs.

Since you've labeled the question C++, you might be interested in using boost::asio, ACE, or some other cross-platform socket library for C++ or for C. Some other cross-platform libraries may be found in the answers to C++ sockets library for cross-platform and Cross platform Networking API.
Assuming that using a third party cross-platform sockets library is not an option for you...
The header <sys/socket.h> is defined in IEEE Std. 1003.1 (POSIX), but sadly Windows is non-compliant with the POSIX standard. The MinGW compiler is a port of GCC for compiling Windows applications, and therefore does not include these POSIX system headers. If you install GCC using Cygwin, then it will include these system headers to emulate a POSIX environment on Windows. Be aware, however, that if you use Cygwin for sockets that a.) you will need to put the cygwin DLL in a place where your application can read it and b.) Cygwin headers and Windows headers don't interact very well (so if you plan on including windows.h
, then you probably don't want to be including sys/socket.h
).
My personal recommendation would be to download a copy of VirtualBox, download a copy of Ubuntu, install Ubuntu into VirtualBox, and then do your coding and testing on Ubuntu. Alternatively, I am told that Microsoft sells a "UNIX subsystem" and that it is pre-installed on certain higher-end editions of Windows, although I have no idea how compliant this system is (and, if it is compliant, with which edition of the UNIX standard it is compliant). Winsockets are also an option, although they can behave in subtly different ways than their POSIX counterparts, even though the signatures may be similar.

I generally store files on the file-system, since that's what its there for, though there are exceptions. For files, the file-system is the most flexible and performant solution (usually).
There are a few problems with storing files on a database - files are generally much larger than your average row - result-sets containing many large files will consume a lot of memory. Also, if you use a storage engine that employs table-locks for writes (ISAM for example), your files table might be locked often depending on the size / rate of files you are storing there.
Regarding security - I usually store the files in a directory that is outside of the document root (not accessible through an http request) and serve them through a script that checks for the proper authorization first.
Guava now provides a new, consistent hashing API that is much more user-friendly than the various hashing APIs provided in the JDK. See Hashing Explained. For a file, you can get the MD5 sum, CRC32 (with version 14.0+) or many other hashes easily:
HashCode md5 = Files.hash(file, Hashing.md5());
byte[] md5Bytes = md5.asBytes();
String md5Hex = md5.toString();
HashCode crc32 = Files.hash(file, Hashing.crc32());
int crc32Int = crc32.asInt();
// the Checksum API returns a long, but it's padded with 0s for 32-bit CRC
// this is the value you would get if using that API directly
long checksumResult = crc32.padToLong();
You can try something like this....
Dim cbTime
Set cbTime = ActiveSheet.CheckBoxes.Add(100, 100, 50, 15)
With cbTime
.Name = "cbTime"
.Characters.Text = "Time"
End With
If ActiveSheet.CheckBoxes("cbTime").Value = 1 Then 'or just cbTime.Value
'checked
Else
'unchecked
End If
I found the best and easiest way to do it is this one because you don't need to add labels, divs or whatsoever.
input { vertical-align: middle; margin-top: -1px;}
You can also output your file in xdot format, then render it in a browser using canviz, a JavaScript library.
To see an example, there is a "Canviz Demo" link on the page above as of November 2, 2014.
You could use the validation plugin for jQuery: http://docs.jquery.com/Plugins/Validation
It happens to have an accept() rule that does exactly what you need: http://docs.jquery.com/Plugins/Validation/Methods/accept#extension
Note that controlling file extension is not bullet proof since it is in no way related to the mimetype of the file. So you could have a .png that's a word document and a .doc that's a perfectly valid png image. So don't forget to make more controls server-side ;)
As others have already mentioned, HTML 4 requires the <style>
tag to be placed in the <head>
section (even though most browsers allow <style>
tags within the body
).
However, HTML 5 includes the scoped
attribute (see update below), which allows you to create style sheets that are scoped within the parent element of the <style>
tag. This also enables you to place <style>
tags within the <body>
element:
<!DOCTYPE html>
<html>
<head></head>
<body>
<div id="scoped-content">
<style type="text/css" scoped>
h1 { color: red; }
</style>
<h1>Hello</h1>
</div>
<h1>
World
</h1>
</body>
</html>
If you render the above code in an HTML-5 enabled browser that supports scoped
, you will see the limited scope of the style sheet.
There's just one major caveat...
At the time I'm writing this answer (May, 2013) almost no mainstream browser currently supports the scoped
attribute. (Although apparently developer builds of Chromium support it.)
HOWEVER, there is an interesting implication of the scoped
attribute that pertains to this question. It means that future browsers are mandated via the standard to allow <style>
elements within the <body>
(as long as the <style>
elements are scoped.)
So, given that:
scoped
attribute<style>
tags within the <body>
<style>
tags within the <body>
...then there is literally no harm * in placing <style>
tags within the body, as long as you future proof them with a scoped
attribute. The only problem is that current browsers won't actually limit the scope of the stylesheet - they'll apply it to the whole document. But the point is that, for all practical purposes, you can include <style>
tags within the <body>
provided that you:
scoped
attribute<body>
will not actually be scoped (because no mainstream browser support exists yet)
* except of course, for pissing off HTML validators...
Finally, regarding the common (but subjective) claim that embedding CSS within HTML is poor practice, it should be noted that the whole point of the scoped
attribute is to accommodate typical modern development frameworks that allow developers to import chunks of HTML as modules or syndicated content. It is very convenient to have embedded CSS that only applies to a particular chunk of HTML, in order to develop encapsulated, modular components with specific stylings.
Update as of Feb 2019, according to the Mozilla documentation, the scoped
attribute is deprecated. Chrome stopped supporting it in version 36 (2014) and Firefox in version 62 (2018). In both cases, the feature had to be explicitly enabled by the user in the browsers' settings. No other major browser ever supported it.
Since you have a list of links, you should be marking them up as a list (and not as paragraphs).
Listamatic has a bunch of examples of how you can style lists of links, including a number that are vertical lists with each link being centred (which is what you appear to be after). It also has a tutorial which explains the principles.
That part of the styling essentially boils down to "Set text-align: center
on an element that is displaying as a block which contains the link text" (that could be the anchor itself (if you make it display as a block) or the list item containing it.
As of SQL Server 2016 you have
DROP TABLE IF EXISTS [foo];

We need to wait for view will be drawn. For this purpose use OnPreDrawListener. Kotlin example:
val preDrawListener = object : ViewTreeObserver.OnPreDrawListener {
override fun onPreDraw(): Boolean {
view.viewTreeObserver.removeOnPreDrawListener(this)
// code which requires view size parameters
return true
}
}
view.viewTreeObserver.addOnPreDrawListener(preDrawListener)
inspired by @dilettante answer, here's my solution as an extension function in kotlin:
/* sets a valid id that isn't in use */
fun View.findAndSetFirstValidId() {
var i: Int
do {
i = Random.nextInt()
} while (findViewById<View>(i) != null)
id = i
}
This is a one-to-one replacement of java.util.Propeties
From the doc:
def __parse(self, lines):
""" Parse a list of lines and create
an internal property dictionary """
# Every line in the file must consist of either a comment
# or a key-value pair. A key-value pair is a line consisting
# of a key which is a combination of non-white space characters
# The separator character between key-value pairs is a '=',
# ':' or a whitespace character not including the newline.
# If the '=' or ':' characters are found, in the line, even
# keys containing whitespace chars are allowed.
# A line with only a key according to the rules above is also
# fine. In such case, the value is considered as the empty string.
# In order to include characters '=' or ':' in a key or value,
# they have to be properly escaped using the backslash character.
# Some examples of valid key-value pairs:
#
# key value
# key=value
# key:value
# key value1,value2,value3
# key value1,value2,value3 \
# value4, value5
# key
# This key= this value
# key = value1 value2 value3
# Any line that starts with a '#' is considerered a comment
# and skipped. Also any trailing or preceding whitespaces
# are removed from the key/value.
# This is a line parser. It parses the
# contents like by line.
You need to write a document.write object:
document.write('<script type="text/javascript" src="file.js" ></script>');
and place it in your main javascript file

As DotNetMensch said but you DO NOT need to add another site in IIS as this can also cause further problems and make things more complicated because you then have a website within a website so the file paths, masterpage paths and web.config paths may need changing. You just need to edit teh bindings of the existing site and add the new subdomain there.
So:
Add sub-domain to DNS records. My host (RackSpace) uses a web portal to do this so you just log in and go to Network->Domains(DNS)->Actions->Create Zone, and enter your subdomain as mysubdomain.domain.com etc, leave the other settings as default
Go to your domain in IIS, right-click->Edit Bindings->Add, and add your new subdomain leaving everything else the same e.g. mysubdomain.domain.com
You may need to wait 5-10 mins for the DNS records to update but that's all you need.
According to http://www.cplusplus.com/reference/std/iterator/distance/, since vec.begin()
is a random access iterator, the distance method uses the -
operator.
So the answer is, from a performance point of view, it is the same, but maybe using distance()
is easier to understand if anybody would have to read and understand your code.
Most of the solutions here did not work for me so I used the one found here

Option 1: Discard tracked and untracked file changes
Discard changes made to both staged and unstaged files.
$ git reset --hard [HEAD]
Then discard (or remove) untracked files altogether.
$ git clean [-f]
Option 2: Stash
You can first stash your changes
$ git stash
And then either drop or pop it depending on what you want to do. See https://git-scm.com/docs/git-stash#_synopsis.
Option 3: Manually restore files to original state
First we switch to the target branch
$ git checkout <branch-name>
List all files that have changes
$ git status
Restore each file to its original state manually
$ git restore <file-path>

3 6 7
4 8 9
In [49]: a.c1[a.c1 == 8].index.tolist()

protected doStuff()
{
// If we want we can still explicitly call the initial method
super.doStuff();
alert("Called from B");
}
}
var a = new A();
a.callDoStuff(); // Will only alert "Called from A"
var b = new B()
b.callDoStuff(); // Will alert "Called from A" then "Called from B"
I've used this method (reported here )
export class AppComponent {
constructor() {
if(document.getElementById("testScript"))
document.getElementById("testScript").remove();
var testScript = document.createElement("script");
testScript.setAttribute("id", "testScript");
testScript.setAttribute("src", "assets/js/test.js");
document.body.appendChild(testScript);
}
}
it worked for me since I wanted to execute a javascript file AFTER THE COMPONENT RENDERED.
The easiest way would be using Substring
string str = "AM0122200204";
string substr = str.Substring(str.Length - 3);
Using the overload with one int
as I put would get the substring
of a string
, starting from the index int
. In your case being str.Length - 3
, since you want to get the last three chars.
I know this is an old question, but I got here because I had a similar problem as everyone above. I solved it by just reading a little closer!
I hadn't noticed there were 2 possible system Images I could choose from, one that contained Google APIs and one that didn't (on my laptop the menu was too small for me to read the (with Google APIs) text appended.
It's a stupid thing to miss, but someone else might have a small screen like I did, and miss this :D
To make 1dp collapse-border around every cell without writing a java code and without creating another xml layout with <shape...>
tag, you can try this solution:
In <TableLayout...>
add
android:background="#CCC"
and android:paddingTop="1dp"
and android:stretchColumns="0"
In <TableRow...>
add
android:background="#CCC"
and android:paddingBottom="1dp"
and android:paddingRight="1dp"
In every cell/child in TableRow, i.e. <TextView...>
add
android:background="#FFF"
and android:layout_marginLeft="1dp"
It is very important to follow paddings and margins as described. This solution will draw a 1dp border aka border-collapse property in (X)HTML/CSS.
Background color in <TableLayout...>
and <TableRow...>
represents a border line color and background in <TextView...>
fills a table cell. You can put some padding in cells if necessary.
An example is here:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#CCC"
android:paddingTop="1dp"
android:stretchColumns="0"
android:id="@+id/tlTable01">
<TableRow
android:background="#CCC"
android:paddingBottom="1dp"
android:paddingRight="1dp">
<TextView
android:layout_marginLeft="1dp"
android:padding="5dp"
android:background="#FFF"
android:text="Item1"/>
<TextView
android:layout_marginLeft="1dp"
android:padding="5dp"
android:background="#FFF"
android:gravity="right"
android:text="123456"/>
</TableRow>
<TableRow
android:background="#CCC"
android:paddingBottom="1dp"
android:paddingRight="1dp">
<TextView
android:layout_marginLeft="1dp"
android:padding="5dp"
android:background="#FFF"
android:text="Item2"/>
<TextView
android:layout_marginLeft="1dp"
android:padding="5dp"
android:background="#FFF"
android:gravity="right"
android:text="456789"/>
</TableRow>
</TableLayout>
Well, if you have Visual Studio (I know it's in 2005, not sure about earlier versions though), you can add the remote machine to your "Server Explorer" tag. At that point, you'll have access to the SERVICES that are running, or can be ran, from that machine (as well as event logs, and queues, and a couple other interesting things).
Thanks for the research FIRESTICK is a solution for non Android based but there's another one Im using if you guys want to try it let me know...
LG, VIZIO, SAMSUNG and PANASONIC TVs are not android based, and you cannot run APKs off of them... You should just buy a fire stick and call it a day. The only TVs that are android-based, and you can install APKs are: SONY, PHILIPS and SHARP, PHILCO and TOSHIBA.
This is not the exact answer to this question, but those who are not able to find setting popup. Their is two ways to open setting pop up.
if you look to support old version pre lolipop
use the same xml code with some changes
instead of normal ImageView --> AppCompatImageView
instead of android:src --> app:srcCompat
here is example
<android.support.v7.widget.AppCompatImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:id="@+id/button"
app:srcCompat="@drawable/ic_more_vert_24dp"
android:tint="@color/primary" />
dont forget update your gradle as @ Sayooj Valsan mention
// Gradle Plugin 2.0+ android { defaultConfig { vectorDrawables.useSupportLibrary = true } } compile 'com.android.support:design:23.4.0'
Notice To any one use vector dont ever ever never give your vector reference to color like this one android:fillColor="@color/primary"
give its hex value .
try this code, it has already a smooth animation when clicked the link.
$(document).on('click', 'a[href^="#"]', function (event) {
event.preventDefault();
$('html, body').animate({
scrollTop: $($.attr(this, 'href')).offset().top - 100
}, 500);
});
You are doing mistake in "configuration_page.jsp" file. here in this file , function loadXMLDoc() 's line number 2 should be like this:
var config=document.getElementsByName('configselect').value;
because you have declared only the name
attribute in your <select>
tag. So you should get this element by name.
After correcting this, it will run without any JavaScript error
//Get
var p = $("#elementId");
var offset = p.offset();
//set
$("#secondElementId").offset({ top: offset.top, left: offset.left});
I faced the issue when i was using ZBar for scanning in tabs. Camera orientation issue. Using below code i was able to resolve issue. This is not the whole code snippet, Please take only help from this.
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
if (isPreviewRunning) {
mCamera.stopPreview();
}
setCameraDisplayOrientation(mCamera);
previewCamera();
}
public void previewCamera() {
try {
// Hard code camera surface rotation 90 degs to match Activity view
// in portrait
mCamera.setPreviewDisplay(mHolder);
mCamera.setPreviewCallback(previewCallback);
mCamera.startPreview();
mCamera.autoFocus(autoFocusCallback);
isPreviewRunning = true;
} catch (Exception e) {
Log.d("DBG", "Error starting camera preview: " + e.getMessage());
}
}
public void setCameraDisplayOrientation(android.hardware.Camera camera) {
Camera.Parameters parameters = camera.getParameters();
android.hardware.Camera.CameraInfo camInfo =
new android.hardware.Camera.CameraInfo();
android.hardware.Camera.getCameraInfo(getBackFacingCameraId(), camInfo);
Display display = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
int rotation = display.getRotation();
int degrees = 0;
switch (rotation) {
case Surface.ROTATION_0:
degrees = 0;
break;
case Surface.ROTATION_90:
degrees = 90;
break;
case Surface.ROTATION_180:
degrees = 180;
break;
case Surface.ROTATION_270:
degrees = 270;
break;
}
int result;
if (camInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
result = (camInfo.orientation + degrees) % 360;
result = (360 - result) % 360; // compensate the mirror
} else { // back-facing
result = (camInfo.orientation - degrees + 360) % 360;
}
camera.setDisplayOrientation(result);
}
private int getBackFacingCameraId() {
int cameraId = -1;
// Search for the front facing camera
int numberOfCameras = Camera.getNumberOfCameras();
for (int i = 0; i < numberOfCameras; i++) {
Camera.CameraInfo info = new Camera.CameraInfo();
Camera.getCameraInfo(i, info);
if (info.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {
cameraId = i;
break;
}
}
return cameraId;
}
filter_by
is used for simple queries on the column names using regular kwargs, like
db.users.filter_by(name='Joe')
The same can be accomplished with filter
, not using kwargs, but instead using the '==' equality operator, which has been overloaded on the db.users.name object:
db.users.filter(db.users.name=='Joe')
You can also write more powerful queries using filter
, such as expressions like:
db.users.filter(or_(db.users.name=='Ryan', db.users.country=='England'))
I'll throw mine in the mix:

this evaluates the if statement once and adds no watch listener BUT you can add an additional attribute to the element that has the set-if called wait-for="somedata.prop" and it will wait for that data or property to be set before evaluating the if statement once. that additional attribute can be very handy if you're waiting for data from an XHR request.
angular.module('setIf',[]).directive('setIf',function () {
return {
transclude: 'element',
priority: 1000,
terminal: true,
restrict: 'A',
compile: function (element, attr, linker) {
return function (scope, iterStartElement, attr) {
if(attr.waitFor) {
var wait = scope.$watch(attr.waitFor,function(nv,ov){
if(nv) {
build();
wait();
}
});
} else {
build();
}
function build() {
iterStartElement[0].doNotMove = true;
var expression = attr.setIf;
var value = scope.$eval(expression);
if (value) {
linker(scope, function (clone) {
iterStartElement.after(clone);
clone.removeAttr('set-if');
clone.removeAttr('wait-for');
});
}
}
};
}
};
});
For those wanting to use Postgresql on OpenSuse (and co), try the following:
zypper --no-refresh in php5-pgsql
* for python 2.x *
Use a trailing comma to avoid a newline.
print "Hey Guys!",
print "This is how we print on the same line."
The output for the above code snippet would be,
Hey Guys! This is how we print on the same line.
* for python 3.x *
for i in range(10):
print(i, end="<separator>") # <separator> = \n, <space> etc.
The output for the above code snippet would be (when <separator> = " "
),
0 1 2 3 4 5 6 7 8 9
I believe Spring Boot supports loading properties maps out of the box with @ConfigurationProperties annotation.
According that docs you can load properties:
my.servers[0]=dev.bar.com
my.servers[1]=foo.bar.com
into bean like this:
@ConfigurationProperties(prefix="my")
public class Config {
private List<String> servers = new ArrayList<String>();
public List<String> getServers() {
return this.servers;
}
}
I used @ConfigurationProperties feature before, but without loading into map. You need to use @EnableConfigurationProperties annotation to enable this feature.
Cool stuff about this feature is that you can validate your properties.
It will be written on a new line if you examine the source code of the page. If you want it to appear on a new line when it is rendered in the browser, you'll have use a <br />
tag instead.
I think you need to separate the form names from its values, one method to do this is to explode (&)
so that you will get attribute=value,attribute2=value
.
My point here is that you will convert the serialized jQuery string into arrays in PHP.
Here is the steps that you should follow to be more specific.
jQuery
to a PHP
page(e.g ajax.php
)
where you use $.ajax
to submit using post or get.(&)
thus separating each
attributes. Now you will get attribute1=value, attribute2=value, now
you will get a php array variable. e.g$data =
array("attribute1=value","attribute2=value")
foreach
on $data
and explode
the (=)
so that you can
separate the attribute from the value, and be sure to urldecode
the value so that it will convert serialized values to the value
that you need, and insert the attribute and its value to a new array
variable, which stores the attribute and the value of the serialized
string.Let me know if you need more clarifications.
To find the HSV value of Green, try following commands in Python terminal
green = np.uint8([[[0,255,0 ]]])
hsv_green = cv2.cvtColor(green,cv2.COLOR_BGR2HSV)
print hsv_green
[[[ 60 255 255]]]
