IDK if this is relevant here, but if you have Git Installed, you can find the openssl in the "C:\Program Files\Git\usr\bin" and that location you can use in the Terminal for your Keystore Command.
oh and yeah the command:
keytool -exportcert -alias keystore -keystore "C:\Users\YOURPATH/filename.jks" | "C:\Program Files\Git\usr\bin\openssl" sha1 -binary | "C:\Program Files\Git\usr\bin\openssl" base64
For int64_t
type:
#include <inttypes.h>
int64_t t;
printf("%" PRId64 "\n", t);
for uint64_t
type:
#include <inttypes.h>
uint64_t t;
printf("%" PRIu64 "\n", t);
you can also use PRIx64
to print in hexadecimal.
cppreference.com has a full listing of available macros for all types including intptr_t
(PRIxPTR
). There are separate macros for scanf, like SCNd64
.
A typical definition of PRIu16 would be "hu"
, so implicit string-constant concatenation happens at compile time.
For your code to be fully portable, you must use PRId32
and so on for printing int32_t
, and "%d"
or similar for printing int
.
Emulation is the process of mimicking the outwardly observable behavior to match an existing target. The internal state of the emulation mechanism does not have to accurately reflect the internal state of the target which it is emulating.
Simulation, on the other hand, involves modeling the underlying state of the target. The end result of a good simulation is that the simulation model will emulate the target which it is simulating.
Ideally, you should be able to look into the simulation and observe properties that you would also see if you looked into the original target. In practice, there may some shortcuts to the simulation for performance reasons -- that is, some internal aspects of the simulation may actually be an emulation.
MAME is an arcade game emulator; Hyperterm is a (not very good) terminal emulator. There's no need to model the arcade machine or a terminal in detail to get the desired emulated behavior.
Flight Simulator is a simulator; SPICE is an electronics simulator. They model as much as possible every detail of the target to represent what the target does in reality.
EDIT: Other responses have pointed out that the goal of an emulation is to able to substitute for the object it is emulating. That's an important point. A simulation's focus is more on the modelling of the internal state of the target -- and the simulation does not necessarily lead to emulation. In particular, a simulation may run far slower than real time. SPICE, for example, cannot substitue for an actual electronics circuit (even if assuming there was some kind of magical device that perfectly interfaces electrical circuits to a SPICE simulation.) A simulation Simulation does not always lead to emulation --
With Graphical User Interface (GUI) in Xcode, you can do the following:
- Go to "
Attribute Inspector
" and setLines
value to0
. By default, it is set to1
.- The Label text can be written in multi-line by hitting
option + return
.
- Now, go to "
Size Inspector
" and set thewidth

position
of the Label.
That's all.
In addition to the native versions, but you may want to try BitNami MAMP Stacks (disclaimer, I am one of the developers). They are completely free, all-in-one bundles of Apache, MySQL, PHP and a several other third-party libraries and utilities that are useful when developing locally. In particular, they are completely self-contained so you can have several one installed at the same time, with different versions of Apache and MySQL and they will not interfere with each other. You can get them from http://bitnami.org/stack/mampstack or directly from the Mac OS X app store https://itunes.apple.com/app/mamp-stack/id571310406
If your command is something where a user needs to choose some action, then use a mutually exclusive group with required=True.
This is kind of an extension to the answer given by pd321.
import argparse
parser = argparse.ArgumentParser()
group = parser.add_mutually_exclusive_group(required=True)
group.add_argument("--batch", action='store', type=int, metavar='pay_id')
group.add_argument("--list", action='store_true')
group.add_argument("--all", action='store_true', help='check all payments')
args=parser.parse_args()
if args.batch:
print('batch {}'.format(args.batch))
if args.list:
print('list')
if args.all:
print('all')
Output:
$ python3 a_test.py
usage: a_test.py [-h] (--batch pay_id | --list | --all)
a_test.py: error: one of the arguments --batch --list --all is required
This only give the basic help. And some of the other answers will give you the full help. But at least your users know they can do -h
That response is a string too, if you want to send the response prettified, for some awkward reason, you could use something like JSON.stringify(anObject, null, 3)
It's important that you set the Content-Type
header to application/json
, too.
var http = require('http');
var app = http.createServer(function(req,res){
res.setHeader('Content-Type', 'application/json');
res.end(JSON.stringify({ a: 1 }));
});
app.listen(3000);
// > {"a":1}
Prettified:
var http = require('http');
var app = http.createServer(function(req,res){
res.setHeader('Content-Type', 'application/json');
res.end(JSON.stringify({ a: 1 }, null, 3));
});
app.listen(3000);
// > {
// > "a": 1
// > }
I'm not exactly sure why you want to terminate it with a newline, but you could just do JSON.stringify(...) + '\n'
to achieve that.
In express you can do this by changing the options instead.
'json replacer'
JSON replacer callback, null by default
'json spaces'
JSON response spaces for formatting, defaults to 2 in development, 0 in production
Not actually recommended to set to 40
app.set('json spaces', 40);
Then you could just respond with some json.
res.json({ a: 1 });
It'll use the 'json spaces
' configuration to prettify it.
For SQL Server 2012 and above: If you place the query into a string then you can get the result set data types like so:
DECLARE @query nvarchar(max) = 'select 12.1 / 10.1 AS [Column1]';
EXEC sp_describe_first_result_set @query, null, 0;
You have two options:
Use a Mark of the Web. This will enable a single html page to load. It See here for details. To do this, add the following to your web page below the doctype and above the html tag:
<!-- saved from url=(0014)about:internet -->
Disable this feature. To do so go to Internet Options->Advanced->Security->Allow Active Content... Then close IE. When you restart IE, it will not give you this error.
this one also gives the no.of lines in a file.
a=open('filename.txt','r')
l=a.read()
count=l.splitlines()
print(len(count))
In a new sheet (where you want to create a new pivot table) press the key combination (Alt+D+P). In the list of data source options choose "Microsoft Excel list of database". Click Next and select the pivot table that you want to use as a source (select starting with the actual headers of the fields). I assume that this range is rather static and if you refresh the source pivot and it changes it's size you would have to re-size the range as well. Hope this helps.
Nothing above worked, this is what worked for me:
ftype Python.File=C:\Path\to\python.exe "%1" %*
This command should be run in Command prompt launched as administrator
Warning: even if the path in this command is set to python35, if you have python36 installed it's going to set the default to python36. To prevent this, you can temporarily change the folder name from Python36
to xxPython36
, run the command and then remove the change to the Python 36 folder.
If you want to pass custom Controller to a form_for while rendering a partial form you can use this:
<%= render 'form', :locals => {:controller => 'my_controller', :action => 'my_action'}%>
and then in the form partial use this local variable like this:
<%= form_for(:post, :url => url_for(:controller => locals[:controller], :action => locals[:action]), html: {class: ""} ) do |f| -%>
Yes you can solve this error by changing the port number of glassfish because the WAMP SERVER or ORACLE database software uses a port number 8080, so there is a conflict of port number.
1)open a path like C:\GlassFish_Server\glassfish\domains\domain1\config\domain.xml.
2)find out the 8080 port number with the help of ctrl+F. You will get the following code...
<network-listener protocol="http-listener-1" port="8080" name="http-listener-1" thread-pool="http-thread-pool" transport="tcp">
3) Change that port number from 8080 to 9090 or 1234 or whatever you like..
4) Save it. Open a Netbeans IDE goto the glassfish server .
5) Right click on the server -> select refresh option.
6) to check the port no. which is given by u just right click on the server-> property.
7) Start the Glassfish server . Yehhh the error is gone...

Here is a guide to JSZIP to create ZIP files by JavaScript. To download files you need to have filesaver.js, You can include those libraries by:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.1.4/jszip.min.js" type="text/javascript"></script>
<script type="text/javascript" src="https://fastcdn.org/FileSaver.js/1.1.20151003/FileSaver.js" ></script>
Now copy this code and this code will download a zip file with a file hello.txt having content Hello World. If everything thing works fine, this will download a file.
<script type="text/javascript">
var zip = new JSZip();
zip.file("Hello.txt", "Hello World\n");
zip.generateAsync({type:"blob"})
.then(function(content) {
// see FileSaver.js
saveAs(content, "file.zip");
});
</script>
Now let's get in to deeper. Create an instance of JSZip.
var zip = new JSZip();
Add a file with a Hello World text:
zip.file("hello.txt", "Hello World\n");
Download the filie with name archive.zip
zip.generateAsync({type:"blob"}).then(function(zip) {
saveAs(zip, "archive.zip");
});

You are looking for scipy.misc.toimage
:
import scipy.misc
rgb = scipy.misc.toimage(np_array)
It seems to be also in scipy 1.0, but has a deprecation warning. Instead, you can use pillow
and PIL.Image.fromarray

Native JSON support has been included in PHP since 5.2 in the form of methods json_encode()
and json_decode()
. You would use the first to output a PHP variable in JSON.
Download the latest "sdk platform" and "sdk build tools" of same version like 23.* for
both from "sdk Managar".
(for reference see above hosted image from back track). Then right click on your project -> properties -> Android -> in "project build properties" select "API level" 23 or the latest one which you updated. Then clean your project once.
Note: But all three should be in same version.
You didn't mention if you are using Excel 2003 or 2007, but you may run into an issue with the # of rows in Excel 2003 being capped at 65,536. If you are using 2007, the limit is 1,048,576.
Also, can I ask what your end goal is for your analysis? If you need to perform many statistical calculations on your data, I would recommend moving out of the Excel environment into something that is more directly suited for data manipulation and analysis, such as R.
There are a variety of options for connecting R to Excel, including
Regardless of what you choose to use to move data in/out of R, the code to change from wide to long format is pretty trivial. I enjoy the melt()
function from the reshape package. That code would look like:
library(reshape)
#Fake data, 4 columns, 20k rows
df <- data.frame(foo = rnorm(20000)
, bar = rlnorm(20000)
, fee = rnorm(20000)
, fie = rlnorm(20000)
)
#Create new object with 1 column, 80k rows
df.m <- melt(df)
From there, you can perform any number of statistical or graphing operations. If you use the RExcel plugin above, you can fire all of this up and run it within Excel itself. The R community is very active and can help address any and all questions you may encounter.
Good luck!
Except using css mask answered by @vals, you can also use transparency gradient background and set background-clip
to text
.
Create proper gradient:
background: linear-gradient(to bottom, rgba(0, 0, 0, 1) 0%, rgba(0, 0, 0, 0) 100%);
Then clip the backgroud with text:
background-clip: text;
color: transparent;

To make it simple, setup.py is run as "__main__"
when you call the install functions the other answers mentioned. Inside setup.py, you should put everything needed to install your package.
The following two sections discuss two things many setup.py modules have.
This function allows you to specify project attributes like the name of the project, the version.... Most importantly, this function allows you to install other functions if they're packaged properly. See this webpage for an example of setuptools.setup
These attributes of setuptools.setup enable installing these types of packages:
Packages that are imported to your project and listed in PyPI using setuptools.findpackages:
packages=find_packages(exclude=["docs","tests", ".gitignore", "README.rst","DESCRIPTION.rst"])
Packages not in PyPI, but can be downloaded from a URL using dependency_links
dependency_links=["http://peak.telecommunity.com/snapshots/",]
In an ideal world, setuptools.setup
would handle everything for you. Unfortunately this isn't always the case. Sometimes you have to do specific things, like installing dependencies with the subprocess command, to get the system you're installing on in the right state for your package. Try to avoid this, these functions get confusing and often differ between OS and even distribution.
xsd.exe does not work well when you have circular references (ie a type can own an element of its own type directly or indirectly).
When circular references exist, I use Xsd2Code. Xsd2Code handles circular references well and works within the VS IDE, which is a big plus. It also has a lot of features you can use like generating the serialization/deserialization code. Make sure you turn on the GenerateXMLAttributes if you are generating serialization though (otherwise you'll get exceptions for ordering if not defined on all elements).
Neither works well with the choice feature. you'll end up with lists/collections of object instead of the type you want. I'd recommend avoiding choice in your xsd if possible as this does not serialize/deserialize well into a strongly typed class. If you don't care about this, though, then it's not a problem.
The any feature in xsd2code deserializes as System.Xml.XmlElement which I find really convenient but may be an issue if you want strong typed objects. I often use any when allowing custom config data, so an XmlElement is convenient to pass to another XML deserializer that is custom defined elsewhere.
Here you get all available services and their status in your local machine.
ServiceController[] services = ServiceController.GetServices();
foreach(ServiceController service in services)
{
Console.WriteLine(service.ServiceName+"=="+ service.Status);

As npup explains in his answer, a simple css rule will only target the attribute value
which means that this doesn't cover the actual value of the html node.
JAVASCRIPT TO THE RESCUE!
Yes it's very possible, using css attribute selectors you can reference input's by their value in this sort of fashion:
input[value="United States"] { color: #F90; }?
from the reference
[att] Match when the element sets the "att" attribute, whatever the value of the attribute.
[att=val] Match when the element's "att" attribute value is exactly "val".
[att~=val] Represents an element with the att attribute whose value is a white space-separated list of words, one of which is exactly "val". If "val" contains white space, it will never represent anything (since the words are separated by spaces). If "val" is the empty string, it will never represent anything either.
[att|=val] Represents an element with the att attribute, its value either being exactly "val" or beginning with "val" immediately followed by "-" (U+002D). This is primarily intended to allow language subcode matches (e.g., the hreflang attribute on the a element in HTML) as described in BCP 47 ([BCP47]) or its successor. For lang (or xml:lang) language subcode matching, please see the :lang pseudo-class.

This answer is in three parts, see below for the official release (v3 and v4)
I couldn't even find the col-lg-push-x or pull classes in the original files for RC1 i downloaded, so check your bootstrap.css file. hopefully this is something they will sort out in RC2.
anyways, the col-push-* and pull classes did exist and this will suit your needs. Here is a demo
<div class="row">
<div class="col-sm-5 col-push-5">
Content B
</div>
<div class="col-sm-5 col-pull-5">
Content A
</div>
<div class="col-sm-2">
Content C
</div>
</div>
Also see This blog post on the subject
col-vp-push-x
= push the column to the right by x number of columns, starting from where the column would normally render -> position: relative
, on a vp or larger view-port.
col-vp-pull-x
= pull the column to the left by x number of columns, starting from where the column would normally render -> position: relative
, on a vp or larger view-port.
vp = xs, sm, md, or lg
x = 1 thru 12
I think what messes most people up, is that you need to change the order of the columns in your HTML markup (in the example below, B comes before A), and that it only does the pushing or pulling on view-ports that are greater than or equal to what was specified. i.e. col-sm-push-5
will only push 5 columns on sm
view-ports or greater. This is because Bootstrap is a "mobile first" framework, so your HTML should reflect the mobile version of your site. The Pushing and Pulling are then done on the larger screens.
<div class="row">
<div class="col-sm-5 col-sm-push-5">
Content B
</div>
<div class="col-sm-5 col-sm-pull-5">
Content A
</div>
<div class="col-sm-2">
Content C
</div>
</div>
View-port >= sm
|A|B|C|
View-port < sm
|B|
|A|
|C|
With v4 comes flexbox and other changes to the grid system and the push\pull classes have been removed in favor of using flexbox ordering.
.order-*
classes to control visual order (where * = 1 thru 12).order-md-*
.order-first
(-1) and .order-last

<div class="col order-2">1st yet 2nd</div>_x000D_
<div class="col order-1">2nd yet 1st</div>_x000D_
</div>

You are missing '/' before Users. I assume that you are using a MAC guessing from the file path names. You root directory is '/'.
Destructors provide an implicit way of freeing unmanaged resources encapsulated in your class, they get called when the GC gets around to it and they implicitly call the Finalize method of the base class. If you're using a lot of unmanaged resources it is better to provide an explicit way of freeing those resources via the IDisposable interface. See the C# programming guide: http://msdn.microsoft.com/en-us/library/66x5fx1b.aspx
One very simple way to make a method asynchronous is to use Task.Yield() method. As MSDN states:
You can use await Task.Yield(); in an asynchronous method to force the method to complete asynchronously.
Insert it at beginning of your method and it will then return immediately to the caller and complete the rest of the method on another thread.
private async Task<DateTime> CountToAsync(int num = 1000)
{
await Task.Yield();
for (int i = 0; i < num; i++)
{
Console.WriteLine("#{0}", i);
}
return DateTime.Now;
}
I know the question asks about macOS, but here is a solution for Linux users who arrive here via Google.
I was having the issue described in this question, having installed the pdfx package via pip.
When I ran it however, nothing...
pip list | grep pdfx
pdfx (1.3.0)
Yet:
which pdfx
pdfx not found
The problem on Linux is that pip install ...
drops scripts into ~/.local/bin
and this is not on the default Debian/Ubuntu $PATH
.
Here's a GitHub issue going into more detail: https://github.com/pypa/pip/issues/3813
To fix, just add ~/.local/bin
to your $PATH
, for example by adding the following line to your .bashrc
file:
export PATH="$HOME/.local/bin:$PATH"
After that, restart your shell and things should work as expected.
With jquery
$("div#id").append('<a href=#>Your LINK TITLE</a>')
With javascript
var new_a = document.createElement('a');
new_a.setAttribute("href", "link url here");
new_a.innerHTML = "your link text";
//add new link to the DOM
document.appendChild(new_a);
If you a framework like Bootstrap you can make any iframe video responsive by using this snippet:
<div class="embed-responsive embed-responsive-16by9">
<iframe class="embed-responsive-item" src="vid.mp4" allowfullscreen></iframe>

Calling object.paintComponent(g)
is an error.
Instead this method is called automatically when the panel is created. The paintComponent()
method can also be called explicitly by the repaint()
method defined in Component
class.
The effect of calling repaint()
is that Swing automatically clears the graphic on the panel and executes the paintComponent
method to redraw the graphics on this panel.
The error was that you cannot use this
in the grep, but you must use a reference to the element. This works:
function findPurpose(purposeName){
return $.grep(purposeObjects, function(n, i){
return n.purpose == purposeName;
});
};
findPurpose("daily");
returns:
[Object { purpose="daily"}]
Put whatever you want to send to PHP in the value
attribute.
<select id="cmbMake" name="Make" >
<option value="">Select Manufacturer</option>
<option value="--Any--">--Any--</option>
<option value="Toyota">Toyota</option>
<option value="Nissan">Nissan</option>
</select>
You can also omit the value
attribute. It defaults to using the text.
If you don't want to change the HTML, you can put an array in your PHP to translate the values:
$makes = array(2 => 'Toyota',
3 => 'Nissan');
$maker = $makes[$_POST['Make']];
you can try these:
document.getElementById("RootNode").onclick = function(){/*do something*/};
or
$('#RootNode').click(function(){/*do something*/});
or
$(document).on("click", "#RootNode", function(){/*do something*/});
There is a point for the first two method which is, it matters where in your page DOM, you should put them, the whole DOM should be loaded, to be able to find the, which is usually it gets solved if you wrap them in a window.onload
or DOMReady
event, like:
//in Vanilla JavaScript
window.addEventListener("load", function(){
document.getElementById("RootNode").onclick = function(){/*do something*/};
});
//for jQuery
$(document).ready(function(){
$('#RootNode').click(function(){/*do something*/});
});
Other answers are great, I just want to add... a different approach usable in PowerShell: Install GNUWin32 utils and use grep to view the lines / redirect the output to file http://gnuwin32.sourceforge.net/
This overwrites the new file every time:
grep "step[49]" logIn.log > logOut.log
This appends the log output, in case you overwrite the logIn file and want to keep the data:
grep "step[49]" logIn.log >> logOut.log
Note: to be able to use GNUWin32 utils globally you have to add the bin folder to your system path.
Unless you're browsing through a proxy, the web servers hosting the sites you want to access must be configured to listen to a port other than 80 or 8080.

}

Any chance the build process is looking into the subdirectories and including something it shouldn't? BTW, you can do a legal checkout, then remove the .svn and all it contains. That should give you the same as an export. Try compiling that, before and after removing the metadata, as it were.
PATTERN FORMAT
A blank line matches no files, so it can serve as a separator for readability.
A line starting with #
serves as a comment.
An optional prefix !
which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.
If the pattern ends with a slash, it is removed for the purpose of the following description, but it would only find a match with a directory. In other words, foo/
will match a directory foo
and paths underneath it, but will not match a regular file or a symbolic link foo
(this is consistent with the way how pathspec works in general in git).
If the pattern does not contain a slash /
, git treats it as a shell glob pattern and checks for a match against the pathname relative to the location of the .gitignore
file (relative to the toplevel of the work tree if not from a .gitignore
file).
Otherwise, git treats the pattern as a shell glob suitable for consumption by fnmatch(3)
with the FNM_PATHNAME
flag: wildcards in the pattern will not match a /
in the pathname. For example, Documentation/*.html
matches Documentation/git.html
but not Documentation/ppc/ppc.html
or tools/perf/Documentation/perf.html
.
A leading slash matches the beginning of the pathname. For example, /*.c
matches cat-file.c
but not mozilla-sha1/sha1.c
.
git help gitignore
or
man gitignore
To use the hex
encoding in Python 3, use

'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")

Had a similar situation myself. I think it is best to create the tar elsewhere and then use -C to tell tar the base directory for the compressed files. Example:
tar -cjf workspace.tar.gz -C <path_to_workspace> $(ls -A <path_to_workspace>)
This way there is no need to exclude your own tarfile. As noted in other comments, -A will list hidden files.
To be able to disable/enable selects first of all your selects need an ID or class. Then you could do something like this:
Disable:
$('#id').attr('disabled', 'disabled');
Enable:
$('#id').removeAttr('disabled');
Try this:
body
{
background:url("images/plaid.jpg") no-repeat fixed center;
}
jsfiddle example: http://jsfiddle.net/Q9Zfa/
First, having the url in href
is best because it allows users to copy links, open in another tab, etc.
In some cases (e.g. sites with frequent HTML changes) it is not practical to bind links every time there is an update.
Normal link:
<a href="https://www.google.com/">Google<a/>
And something like this for JS:
$("a").click(function (e) {
e.preventDefault();
var href = $(this).attr("href");
window.open(href);
return false;
});
The benefits of this method are clean separation of markup and behavior and doesn't have to repeat the function calls in every link.
If you don't want to bind every time, however, you can use onclick and pass in the element and event, e.g.:
<a href="https://www.google.com/" onclick="return Handler(this, event);">Google</a>
And this for JS:
function Handler(self, e) {
e.preventDefault();
var href = $(self).attr("href");
window.open(href);
return false;
}
The benefit to this method is that you can load in new links (e.g. via AJAX) whenever you want without having to worry about binding every time.

Yes, the Session object might be null, but only in certain circumstances, which you will only rarely run into:
If you only have code in pages, you won't run into this. Most of my ASP .NET code uses Session without checking for null repeatedly. It is, however, something to think about if you are developing an IHttpModule or otherwise is down in the grittier details of ASP .NET.
In answer to the comment: Whether or not session state is available depends on whether the AcquireRequestState event has run for the request. This is where the session state module does it's work by reading the session cookie and finding the appropiate set of session variables for you.
AcquireRequestState runs before control is handed to your Page. So if you are calling other functionality, including static classes, from your page, you should be fine.
If you have some classes doing initialization logic during startup, for example on the Application_Start event or by using a static constructor, Session state might not be available. It all boils down to whether there is a current request and AcquireRequestState has been run.
Also, should the client have disabled cookies, the Session object will still be available - but on the next request, the user will return with a new empty Session. This is because the client is given a Session statebag if he does not have one already. If the client does not transport the session cookie, we have no way of identifying the client as the same, so he will be handed a new session again and again.
This is how I finally did it! You can put a layer (full sized) over your body with high z-index and, of course hidden. You will make it visible when the window is open, make it focused on click over parent window (the layer), and finally will disappear it when the opened window is closed or submitted or whatever.
.layer
{
position: fixed;
opacity: 0.7;
left: 0px;
top: 0px;
width: 100%;
height: 100%;
z-index: 999999;
background-color: #BEBEBE;
display: none;
cursor: not-allowed;
}
and layer in the body:
<div class="layout" id="layout"></div>
function that opens the popup window:
var new_window;
function winOpen(){
$(".layer").show();
new_window=window.open(srcurl,'','height=750,width=700,left=300,top=200');
}
keeping new window focused:
$(document).ready(function(){
$(".layout").click(function(e) {
new_window.focus();
}
});
and in the opened window:
function submit(){
var doc = window.opener.document,
doc.getElementById("layer").style.display="none";
window.close();
}
window.onbeforeunload = function(){
var doc = window.opener.document;
doc.getElementById("layout").style.display="none";
}
I hope it would help :-)
May be use like this
if($match > 0){
$msg = 'Login Complete! Thanks';
echo "<a href='".$link_address."'>link</a>";
}
else{
$msg = 'Login Failed!<br /> Please make sure that you enter the correct details and that you have activated your account.';
}
You can also do more succinctly:
df.sort_index(axis=1)
Make sure you assign the result back:
df = df.sort_index(axis=1)
Or, do it in-place:
df.sort_index(axis=1, inplace=True)
In Excel for Mac at least, you can do this by saving as "CSV for MS DOS" which adds double quotes for any field which needs them.
select regexp_replace(field, E'[\\n\\r]+', ' ', 'g' )

[Kotlin version] I created this extension that also checks if the desired color has enough contrast to hide the System UI, like Battery Status Icon, Clock, etc, so we set the System UI white or black according to this.
fun Activity.coloredStatusBarMode(@ColorInt color: Int = Color.WHITE, lightSystemUI: Boolean? = null) {
var flags: Int = window.decorView.systemUiVisibility // get current flags
var systemLightUIFlag = View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
var setSystemUILight = lightSystemUI
if (setSystemUILight == null) {
// Automatically check if the desired status bar is dark or light
setSystemUILight = ColorUtils.calculateLuminance(color) < 0.5
}
flags = if (setSystemUILight) {
// Set System UI Light (Battery Status Icon, Clock, etc)
removeFlag(flags, systemLightUIFlag)
} else {
// Set System UI Dark (Battery Status Icon, Clock, etc)
addFlag(flags, systemLightUIFlag)
}
window.decorView.systemUiVisibility = flags
window.statusBarColor = color
}
private fun containsFlag(flags: Int, flagToCheck: Int) = (flags and flagToCheck) != 0
private fun addFlag(flags: Int, flagToAdd: Int): Int {
return if (!containsFlag(flags, flagToAdd)) {
flags or flagToAdd
} else {
flags
}
}
private fun removeFlag(flags: Int, flagToRemove: Int): Int {
return if (containsFlag(flags, flagToRemove)) {
flags and flagToRemove.inv()
} else {
flags
}
}

In your first example, you are correct. The batch will hit the commit transaction, regardless of whether the try block fires.
In your second example, I agree with other commenters. Using the success flag is unnecessary.
I consider the following approach to be, essentially, a light weight best practice approach.
If you want to see how it handles an exception, change the value on the second insert from 255 to 256.
CREATE TABLE #TEMP ( ID TINYINT NOT NULL );
INSERT INTO #TEMP( ID ) VALUES ( 1 )
BEGIN TRY
BEGIN TRANSACTION
INSERT INTO #TEMP( ID ) VALUES ( 2 )
INSERT INTO #TEMP( ID ) VALUES ( 255 )
COMMIT TRANSACTION
END TRY
BEGIN CATCH
DECLARE
@ErrorMessage NVARCHAR(4000),
@ErrorSeverity INT,
@ErrorState INT;
SELECT
@ErrorMessage = ERROR_MESSAGE(),
@ErrorSeverity = ERROR_SEVERITY(),
@ErrorState = ERROR_STATE();
RAISERROR (
@ErrorMessage,
@ErrorSeverity,
@ErrorState
);
ROLLBACK TRANSACTION

Upcoming Oracle 19c will support DISTINCT
with LISTAGG
.
This feature is coming with 19c:
SQL> select deptno, listagg (distinct sal,', ') within group (order by sal) 2 from scott.emp 3 group by deptno;
EDIT:
The LISTAGG aggregate function now supports duplicate elimination by using the new DISTINCT keyword. The LISTAGG aggregate function orders the rows for each group in a query according to the ORDER BY expression and then concatenates the values into a single string. With the new DISTINCT keyword, duplicate values can be removed from the specified expression before concatenation into a single string. This removes the need to create complex query processing to find the distinct values prior to using the aggregate LISTAGG function. With the DISTINCT option, the processing to remove duplicate values can be done directly within the LISTAGG function. The result is simpler, faster, more efficient SQL.
You can check the implementation of CPython's dicttype
on GitHub. This is the signature of method that implements the dict iterator:
_PyDict_Next(PyObject *op, Py_ssize_t *ppos, PyObject **pkey,
PyObject **pvalue, Py_hash_t *phash)
Use the PHP function serialize()
to convert arrays to strings. These strings can easily be stored in MySQL database. Using unserialize()
they can be converted to arrays again if needed.

then you load your config with
var config = RegisterCompaniesConfig.GetConfig();

any?
isn't the same as not empty?
in some cases.
>> [nil, 1].any?
=> true
>> [nil, nil].any?
=> false
From the documentation:
If the block is not given, Ruby adds an implicit block of {|obj| obj} (that is any? will return true if at least one of the collection members is not false or nil).
Do it like this:
var value = $("#text").val(); // value = 9.61 use $("#text").text() if you are not on select box...
value = value.replace(".", ":"); // value = 9:61
// can then use it as
$("#anothertext").val(value);
Updated to reflect to current version of jQuery. And also there are a lot of answers here that would best fit to any same situation as this. You, as a developer, need to know which is which.
To replace multiple characters at a time use some thing like this: name.replace(/&/g, "-")
. Here I am replacing all &
chars with -
. g
means "global"
Note - you may need to add square brackets to avoid an error - title.replace(/[+]/g, " ")

A debugging script (jquery solution based on the answer above by hashchange)
function getAttributes ( $node ) {
$.each( $node[0].attributes, function ( index, attribute ) {

You can use simply if
statement under select
query as like I have described below
if(some_condition,if_satisfied,not_satisfied)
SELECT IF(IDParent < 1,ID,IDParent) FROM yourTable ;
When a constructor creates an object, that object implicitly references the constructor’s “prototype” property for the purpose of resolving property references. The constructor’s “prototype” property can be referenced by the program expression constructor.prototype, and properties added to an object’s prototype are shared, through inheritance, by all objects sharing the prototype.
If you desire to use Python 3, you can use the following:
import json
import urllib.request
req = urllib.request.Request('url')
with urllib.request.urlopen(req) as response:
result = json.loads(response.readall().decode('utf-8'))

Technically, to repair your statement, you can add LIMIT 1
to the subquery to ensure that at most 1 row is returned. That would remove the error, your code would still be nonsense.
... 'SELECT store_key FROM store LIMIT 1' ...
Practically, you want to match rows somehow instead of picking an arbitrary row from the remote table store
to update every row of your local table customer
.
Your rudimentary question doesn't provide enough details, so I am assuming a text column match_name
in both tables (and UNIQUE
in store
) for the sake of this example:
... 'SELECT store_key FROM store
WHERE match_name = ' || quote_literal(customer.match_name) ...
But that's an extremely expensive way of doing things.
Ideally, you should completely rewrite the statement.
UPDATE customer c
SET customer_id = s.store_key
FROM dblink('port=5432, dbname=SERVER1 user=postgres password=309245'
,'SELECT match_name, store_key FROM store')
AS s(match_name text, store_key integer)
WHERE c.match_name = s.match_name
AND c.customer_id IS DISTINCT FROM s.store_key;
This remedies a number of problems in your original statement.
Obviously, the basic problem leading to your error is fixed.
It's almost always better to join in additional relations in the FROM
clause of an UPDATE
statement than to run correlated subqueries for every individual row.
When using dblink, the above becomes a thousand times more important. You do not want to call dblink()
for every single row, that's extremely expensive. Call it once to retrieve all rows you need.
With correlated subqueries, if no row is found in the subquery, the column gets updated to NULL, which is almost always not what you want.
In my updated form, the row only gets updated if a matching row is found. Else, the row is not touched.
Normally, you wouldn't want to update rows, when nothing actually changes. That's expensively doing nothing (but still produces dead rows). The last expression in the WHERE
clause prevents such empty updates:
AND c.customer_id IS DISTINCT FROM sub.store_key
There is another way of doing so:
<span style="width: 10px"></span>
You can adjust the amount of space using the width property.
Your code would be:
<div style="text-align: center">
<asp:Button ID="btnSubmit" runat="server" Text="Submit" Width="89px" OnClick="btnSubmit_Click" />
<span style="width: 10px"></span>
<asp:Button ID="btnClear" runat="server" Text="Clear" Width="89px" OnClick="btnClear_Click" />
</div>
The method works if you provide an array. The output of
String[] helloWorld = {"Hello", "World"};
System.out.println(helloWorld);
System.out.println(Arrays.toString(helloWorld));
is
[Ljava.lang.String;@45a877
[Hello, World]
(the number after @
is almost always different)

The plus sign is the historic encoding for a space character in URL parameters, as documented in the help for the urlencode()

That same page contains the answer you need - use rawurlencode()
instead to get RFC 3986 compatible encoding.
Your solution requires some ajax method to pass the html to a back-end server that has a html to pdf facility and then returning the pdf output generated back to the browser.
First setting up the client side code, we will setup the jquery code as
var options = {
"url": "/pdf/generate/convert_to_pdf.php",
"data": "data=" + $("#content").html(),
"type": "post",
}
$.ajax(options)
Then intercept the data from the html2pdf generation script (somewhere from the internet).
convert_to_pdf.php
(given as url in JQUERY code) looks like this -
<?php
$html = $_POST['data'];
$pdf = html2pdf($html);
header("Content-Type: application/pdf"); //check this is the proper header for pdf
header("Content-Disposition: attachment; filename='some.pdf';");
echo $pdf;
?>
A kernel is the part of the operating system that mediates access to system resources. It's responsible for enabling multiple applications to effectively share the hardware by controlling access to CPU, memory, disk I/O, and networking.
An operating system is the kernel plus applications that enable users to get something done (i.e compiler, text editor, window manager, etc).
In Project
It's as the error message says "The value violated the integrity constraints for the column" for column "Copy of F2"
Make it so it doesn't violate the value in the target table. What the allowable values are, data types, etc are not provided in your question so we cannot be more specific in answering.
To address the downvote, No, really it's as it says: you are putting something into a column that is not allowed. It could be Faizan points out, that you're putting a NULL into a NOT NULLable column, but it could be a whole host of other things and as the original poster never provided any update, we're left to guess. Was there a foreign key constraint that the insert violated? Maybe there's a check constraint that got blown? Maybe the source column in Excel has a valid date value for Excel that is not valid for the target column's date/time data type.
Thus, baring concrete information, the best possible answer is "don't do the thing that breaks it" In this case, something about "Copy of F2" is bad for the target column. Give us table definitions, supplied values, etc, then you can specific answers.
Telling people to make a NOT NULLable column into a NULLable one might be the right answer. It might also be the most horrific answer known to mankind. If an existing process expects there to always be a value in column "Copy of F2" changing the constraint to NULL can wreak havoc on existing queries. For example
SELECT * FROM ArbitraryTable AS T WHERE T.[Copy of F2] = '';
Currently, that query retrieves everything that was freshly imported because Copy of F2
is a poorly named status indicator. That data needs to get fed into the next system so... bills can get paid. As soon as you make it such that unprocessed rows can have a NULL value, the above query no longer satisfies that. Bills don't get paid, collections repos your building and now you're out of a job, all because you didn't do impact analysis, etc, etc.

OK. I finally solved this problem. Here follows my solution used in https://sqlflow.org/sqlflow.
To make the demo self-contained, I moved all necessary code to https://github.com/wangkuiyi/mysql-server-in-docker.
I don't use the official image on DockerHub.com https://hub.docker.com/r/mysql/mysql-server. Instead, I made my own by installing MySQL on Ubuntu 18.04. This approach gives me the chance to start mysqld and bind it to 0.0.0.0 (all IPs).
For details, please refer to these lines in my GitHub repo.
SQLFLOW_MYSQL_HOST=${SQLFLOW_MYSQL_HOST:-0.0.0.0}
echo "Start mysqld ..."
sed -i "s/.*bind-address.*/bind-address = ${SQLFLOW_MYSQL_HOST}/" \
/etc/mysql/mysql.conf.d/mysqld.cnf
service mysql start
git clone https://github.com/wangkuiyi/mysql-server-in-docker
cd mysql-server-in-docker
docker build -t mysql:yi .
docker run --rm -d -p 23306:3306 mysql:yi
apt-get
.
sudo apt-get install -y mysql-client
mysql --host 127.0.0.1 --port 23306 --user root -proot
We can run MySQL client from even another container (on the same host).
docker run --rm -it --net=host mysql/mysql-server mysql \
-h 127.0.0.1 -P 13306 -u root -proot
On my iMac, I install the MySQL client using Homebrew.
brew install mysql-client
export PATH="/usr/local/opt/mysql-client/bin:$PATH"
Then, I can access the above Ubuntu host (192.168.1.22).
mysql -h 192.168.1.22 -P 13306 -u root -proot
I can even run MySQL client in a container running on the iMac to connect to the MySQL server in a container on my Ubuntu workstation.
docker run --rm -it --net=host mysql/mysql-server mysql \
-h 192.168.1.22 -P 13306 -u root -proot
In the case that we run MySQL client and server in separate containers running on the same host -- this could happen when we are setting up a CI, we don't need to build our own MySQL server Docker image. Instead, we can use the --net=container:mysql_server_container_name
when we run the client container.
To start the server
docker run --rm -d --name mysql mysql/mysql-server
To start the client
docker run --rm -it --net=container:mysql mysql/mysql-server mysql \
-h 127.0.0.1 -P 3306 -u root -proot

x = raw_input('Enter the numbers into the array: ')
data.append(x)
print(data)
Now this doesn't do any error checking and it stores data as a string.
public function record_count() {
return $this->db->count_all("tablename");
}

In my case, I was creating an object declared and initialized together. I just initialized in the constructor or what you can initialize the object when required.
Here are the steps that i took to solve the issue and you can try also
ssh-keygen

and open a file named id_rsa.pub
in notepad and copy the keySettings
and select the option SSH and GPS keys
.git push origin master

Simplified and minified version (about 3.5k) of this nice implementation http://pajhome.org.uk/crypt/md5/md5.html

add this in your upload.php or where you would send your request (for example if you have upload.html and you need to attach the files to upload.php, then copy and paste these 4 lines). Also if you're using CORS plugins/addons in chrome/mozilla be sure to toggle them more than one time,in order for CORS to be enabled

var clearLoading = function () {
var search = $('#search');
search.html(search.data('normal-text'));
};
setInterval(() => {

By default, for all collection and map objects the fetching rule is FetchType.LAZY
and for other instances it follows the FetchType.EAGER
policy.
In brief, @OneToMany
and @ManyToMany
relations does not fetch the related objects (collection and map) implicictly but the retrieval operation is cascaded through the field in @OneToOne
and @ManyToOne
ones.
System.out.printf("%.2f", number);
BUT, this will round the number to the nearest decimal point you have mentioned.(As in your case you will get 3.14 since rounding 3.14159 to 2 decimal points will be 3.14)
Since the function printf will round the numbers the answers for some other numbers may look like this,
System.out.printf("%.2f", 3.14136); -> 3.14
System.out.printf("%.2f", 3.14536); -> 3.15
System.out.printf("%.2f", 3.14836); -> 3.15
If you just need to cutoff the decimal numbers and limit it to a k
decimal numbers without rounding,
lets say k = 2.
System.out.printf("%.2f", 3.14136 - 0.005); -> 3.14
System.out.printf("%.2f", 3.14536 - 0.005); -> 3.14
System.out.printf("%.2f", 3.14836 - 0.005); -> 3.14
I wonder whether the below method is what you want.
You can use defaultdict
.
>>> from collections import defaultdict
>>> s = [('red',1), ('blue',2), ('red',3), ('blue',4), ('red',1), ('blue',4)]
>>> d = defaultdict(list)
>>> for k, v in s:
d[k].append(v)
>>> sorted(d.items())
[('blue', [2, 4, 4]), ('red', [1, 3, 1])]
You can also specify context location relatively to current classpath, which may be preferable
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Projections and Selections are two unary operations in Relational Algebra and has practical applications in RDBMS (relational database management systems).
In practical sense, yes Projection means selecting specific columns (attributes) from a table and Selection means filtering rows (tuples). Also, for a conventional table, Projection and Selection can be termed as vertical and horizontal slicing or filtering.
Wikipedia provides more formal definitions of these with examples and they can be good for further reading on relational algebra:
A great One Image slider : https://github.com/daimajia/AndroidImageSlider Check it
YourListType ListName = (List<YourListType>)Session["SessionName"];
Another alternative is String.format()
. We are using it in jcabi-log (static utility wrapper around slf4j).
Logger.debug(this, "some variable = %s", value);
It's much more maintainable and extendable. Besides, it's easy to translate.
If the author has a GitHub account, just click the author's username from anywhere in the commit history, and the commits you can see will be filtered down to those by that author:
You can also click the 'n commits' link below their name on the repo's "contributors" page:
Alternatively, you can directly append ?author=<theusername>
or ?author=<emailaddress>
to the URL. For example, https://github.com/jquery/jquery/commits/master?author=dmethvin or https://github.com/jquery/jquery/commits/[email protected] both give me:
For authors without a GitHub account, only filtering by email address will work, and you will need to manually add ?author=<emailaddress>
to the URL - the author's name will not be clickable from the commits list.
You can also get the list of commits by a particular author from the command line using
git log --author=[your git name]
Example:
git log --author=Prem
Although ANSI C does not have this mechanism, it is possible to use itoa() as a shortcut:
char buffer [33];
itoa (i,buffer,2);
printf ("binary: %s\n",buffer);
Here's the origin:
It is non-standard C, but K&R mentioned the implementation in the C book, so it should be quite common. It should be in stdlib.h.
I face the similar issue and surprisingly meta tag didn't work this time. Turns out the company I currently cooperate with has this enterprise mode setting which has priority over meta tag.
We can't change the setting cause policy issue. Luckily I don't really need any fancy features but basic usage of jQuery so my final solution is to switch its version to 1.12 for better compatibility.
Other answers have suggested using TryParse
, which might fit your needs, but the safest way to provide the functionality of the IsNumeric
function is to reference the VB library and use the IsNumeric
function.
IsNumeric
is more flexible than TryParse
. For example, IsNumeric
returns true
for the string "$100"
, while the TryParse
methods all return false
.
To use IsNumeric
in C#, add a reference to Microsoft.VisualBasic.dll. The function is a static method of the Microsoft.VisualBasic.Information
class, so assuming you have using Microsoft.VisualBasic;
, you can do this:
if (Information.IsNumeric(txtMyText.Text.Trim())) //...
I'm afraid I don't think there's a shortcut to do this - if only someone would write a linq wrapper for VB6!
You could write a function that does it by looping through the array and checking each entry - I don't think you'll get cleaner than that.
There's an example article that provides some details here: http://www.vb6.us/tutorials/searching-arrays-visual-basic-6
Please try this one..
create table client (
val_cli integer
,status varchar2(10)
);
---------------------
begin
insert into client
select 1, 'void' from dual
union all
select 4, 'void' from dual
union all
select 1, 'void' from dual
union all
select 6, 'void' from dual
union all
select 10, 'void' from dual;
end;
---------------------
select * from client;
---------------------
declare
counter integer := 0;
begin
for val in 1..10
loop
update client set status = 'updated' where val_cli = val;
if sql%rowcount = 0 then
dbms_output.put_line('no client with '||val||' val_cli.');
else
dbms_output.put_line(sql%rowcount||' client updated for '||val);
counter := counter + sql%rowcount;
end if;
end loop;
dbms_output.put_line('Number of total lines affected update operation: '||counter);
end;
---------------------
select * from client;
--------------------------------------------------------
Result will be like below:
2 client updated for 1
no client with 2 val_cli.
no client with 3 val_cli.
1 client updated for 4
no client with 5 val_cli.
1 client updated for 6
no client with 7 val_cli.
no client with 8 val_cli.
no client with 9 val_cli.
1 client updated for 10
Number of total lines affected update operation: 5
With PHP 7.0+ now here you can do the following:
$dateString = substr($millseconds_go_here,0,10);
$drawDate = new \DateTime(Date('Y-m-d H:i',$dateString));
$drawDate->setTimezone(new \DateTimeZone('UTC'));
This does the following in order:
Date()
can handle the date.DateTime()
can then allow you to modify the time zone you are in, but ensure that date_default_timezone_set("Timezone");
is set before you use DateTime()
functions and classes.DateTime()
classes or functions are used.This also handles the keyboard activation.

In Framework 2.0 you can use (It list files of root folder, it's best the most popular answer):

{
try
{
foreach (string f in Directory.GetFiles(dir))
Console.WriteLine(f);
foreach (string d in Directory.GetDirectories(dir))
{
Console.WriteLine(d);
DirSearch(d);
}
}
catch (System.Exception ex)
{
Console.WriteLine(ex.Message);
}
}

Recently faced a problem with fetching 'Origin' request header, then I found this question. But pretty confused with the results, req.get('host')
is deprecated, that's why giving Undefined
.
Use,
req.header('Origin');
req.header('Host');
// this method can be used to access other request headers like, 'Referer', 'User-Agent' etc.
I think that every JSON response should contain a property (e.g. {authenticated: false}) and the client has to test it everytime: if false, then the Angular controller/service will "redirect" to the login page.
And what happen if the user catch de JSON and change the bool to True?
I think you should never rely on client side to do these kind of stuff. If the user is not authenticated, the server should just redirect to a login/error page.
Additional attributes (in this case, the second onClick
) will be ignored. So, instead of onclick
calling both fbLikeDump();
and WriteCookie();
, it will only call fbLikeDump();
. To fix, simply define a single onclick
attribute and call both functions within it:
<input type="button" value="Don't show this again! " onclick="fbLikeDump();WriteCookie();" />
Does this really make sense?
There is no "first" record in a relational database, you can only delete one random record.
I think it is better if you just created it like this:
var arr = [];
arr = {
key1: 'value1',
key2:'value2'
};
For more info, take a look at this:
Here is another version. If your Scenario requires Saturday to be 1st day of Week and Friday to be last day of Week, the below code will handle that:
DECLARE @myDate DATE = GETDATE()
SELECT @myDate,

DATEADD(DD,-(CHOOSE(DATEPART(dw, @myDate), 1,2,3,4,5,6,0)),@myDate) AS WeekStartDate,
DATEADD(DD,7-CHOOSE(DATEPART(dw, @myDate), 2,3,4,5,6,7,1),@myDate) AS WeekEndDate
You can create an anchor like the one showed below to download the base64 pdf:
<a download=pdfTitle href=pdfData title='Download pdf document' />
where pdfData is your base64 encoded pdf like "data:application/pdf;base64,JVBERi0xLjQKJcOkw7zDtsOfCjIgMCBvYmoKPDwvTGVuZ3RoIDMgMCBSL0ZpbHRlci9GbGF0ZURlY29kZT4+CnN0cmVhbQp4nO1cyY4ktxG911fUWUC3kjsTaBTQ1Ytg32QN4IPgk23JMDQ2LB/0+2YsZAQzmZk1PSPIEB..."
Using Math.floor()
is one way of doing this.

Forget using plt.title
and place the text directly with plt.text
. An over-exaggerated example is given below:
import pylab as plt
fig = plt.figure(figsize=(5,10))
figure_title = "Normal title"
ax1 = plt.subplot(1,2,1)
plt.title(figure_title, fontsize = 20)
plt.plot([1,2,3],[1,4,9])
figure_title = "Raised title"
ax2 = plt.subplot(1,2,2)
plt.text(0.5, 1.08, figure_title,
horizontalalignment='center',
fontsize=20,
transform = ax2.transAxes)
plt.plot([1,2,3],[1,4,9])
plt.show()
If the case is:
n=int(input())
Instead of -> for i in n: -> gives error- 'int' object is not iterable
Use -> for i in range(0,n): -> works fine..!

Yes - you would probably be arrested for your terriable abuse of strcat !
Take a look at getline() it reads the data a line at a time but importantly it can limit the number of characters you read, so you don't overflow the buffer.
Strcat is relatively slow because it has to search the entire string for the end on every character insertion. You would normally keep a pointer to the current end of the string storage and pass that to getline as the position to read the next line into.
You could do this:
find ./ -type f -ls |grep '10 Sep'
Example:
[root@pbx etc]# find /var/ -type f -ls | grep "Dec 24"
791235 4 -rw-r--r-- 1 root root 29 Dec 24 03:24 /var/lib/prelink/full
798227 288 -rw-r--r-- 1 root root 292323 Dec 24 23:53 /var/log/sa/sar24
797244 320 -rw-r--r-- 1 root root 321300 Dec 24 23:50 /var/log/sa/sa24
CouchDB and MySQL are two very different beasts. JSON is the native way to store stuff in CouchDB. In MySQL, the best you could do is store JSON data as text in a single field. This would entirely defeat the purpose of storing it in an RDBMS and would greatly complicate every database transaction.
Don't.
Having said that, FriendFeed seemed to use an extremely custom schema on top of MySQL. It really depends on what exactly you want to store, there's hardly one definite answer on how to abuse a database system so it makes sense for you. Given that the article is very old and their main reason against Mongo and Couch was immaturity, I'd re-evaluate these two if MySQL doesn't cut it for you. They should have grown a lot by now.
So you need a natural sort ?
If so, than maybe this script by Brian Huisman based on David koelle's work would be what you need.
It seems like Brian Huisman's solution is now directly hosted on David Koelle's blog:

Assuming you have the menuStrip

ToolStripMenuItem item = menuStrip.Items
.OfType<ToolStripMenuItem>()
.SelectMany(it => it.DropDownItems.OfType<ToolStripMenuItem>())
.SingleOrDefault(n => n.Name == "MyMenu");
For deeper menu levels add more SelectMany operators in the statement.
if you want to search all menu items in the strip then use
ToolStripMenuItem item = menuStrip.Items
.Find("MyMenu",true)
.OfType<ToolStripMenuItem>()
.Single();
However, make sure each menu has a different name to avoid exception thrown by key duplicates.
To avoid exceptions you could use FirstOrDefault
instead of SingleOrDefault
/ Single
, or just return a sequence if you might have Name
duplicates.
I wrote a function wrapper called bar()
for barplot()
to do what you are trying to do here, since I need to do similar things frequently. The Github link to the function is here. After copying and pasting it into R, you do
bar(dv = Species,
factors = c(Category, Reason),
dataframe = Reasonstats,
errbar = FALSE,
ylim=c(0, 140)) #I increased the upper y-limit to accommodate the legend.
The one convenience is that it will put a legend on the plot using the names of the levels in your categorical variable (e.g., "Decline" and "Improved"). If each of your levels has multiple observations, it can also plot the error bars (which does not apply here, hence errbar=FALSE
Use:
DefaultTableModel model = new DefaultTableModel();
JTable table = new JTable(model);
// Create a couple of columns
model.addColumn("Col1");
model.addColumn("Col2");
// Append a row
model.addRow(new Object[]{"v1", "v2"});
Yes the above answers describing the corect way to sort datatable
DataView dv = ft.DefaultView;
dv.Sort = "occr desc";
DataTable sortedDT = dv.ToTable();
But in addition to this, to select particular row in it you can use LINQ and try following
var Temp = MyDataSet.Tables[0].AsEnumerable().Take(1).CopyToDataTable();
I've tried different ways of blocking scrolling when the arrow keys are pressed, both jQuery and native Javascript - they all work fine in Firefox, but don't work in recent versions of Chrome.
Even the explicit {passive: false}
property for window.addEventListener
, which is recommended as the only working solution, for example here.
In the end, after many tries, I found a way that works for me in both Firefox and Chrome:
window.addEventListener('keydown', (e) => {
if (e.target.localName != 'input') { // if you need to filter <input> elements
switch (e.keyCode) {
case 37: // left
case 39: // right
e.preventDefault();
break;
case 38: // up
case 40: // down
e.preventDefault();
break;
default:
break;
}
}
}, {
capture: true, // this disables arrow key scrolling in modern Chrome
passive: false // this is optional, my code works without it
});
Quote for EventTarget.addEventListener()
from MDN
options Optional
An options object specifies characteristics about the event listener. The available options are:capture
ABoolean
indicating that events of this type will be dispatched to the registeredlistener
before being dispatched to anyEventTarget
beneath it in the DOM tree.
once
...
passive
ABoolean
that, if true, indicates that the function specified bylistener
will never callpreventDefault()
. If a passive listener does callpreventDefault()
, the user agent will do nothing other than generate a console warning. ...
I can see what @Þaw mentioned :
$ENROLLEES = $this->load->database('ENROLLEES', TRUE);
$ACCOUNTS = $this->load->database('ACCOUNTS', TRUE);
CodeIgniter supports multiple databases. You need to keep both database reference in separate variable as you did above. So far you are right/correct.
Next you need to use them as below:
$ENROLLEES->query();
$ENROLLEES->result();
and
$ACCOUNTS->query();
$ACCOUNTS->result();
Instead of using
$this->db->query();
$this->db->result();
See this for reference: http://ellislab.com/codeigniter/user-guide/database/connecting.html
You have the following solution from https://www.mkyong.com/java/java-how-to-compare-two-sets/
public static boolean equals(Set<?> set1, Set<?> set2){
if(set1 == null || set2 ==null){
return false;
}
if(set1.size() != set2.size()){
return false;
}
return set1.containsAll(set2);
}
Or if you prefer to use a single return statement:
public static boolean equals(Set<?> set1, Set<?> set2){
return set1 != null
&& set2 != null
&& set1.size() == set2.size()
&& set1.containsAll(set2);
}
Your question is a bit vague, but I suppose UPSERT
could be considered a design pattern. For languages that don't implement MERGE
, a number of alternatives to solve the problem (if a suitable rows exists, UPDATE
; else INSERT
) exist.
Editor's note: this is a very dangerous approach, if you are using a version of PHP old enough to use it. It opens your code to man-in-the-middle attacks and removes one of the primary purposes of an encrypted connection. The ability to do this has been removed from modern versions of PHP because it is so dangerous. The only reason this has been upvoted 70 time is because people are lazy. DO NOT DO THIS.
I know it's a (very) old question and it's about command line, but when I searched Google for "SSL: no alternative certificate subject name matches target host name", this was the first hit.
It took me a good while to figure out the answer so hope this saves someone a lot of time! In PHP add this to your cUrl setopts:
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
p.s: this should be a temporary solution. Since this is a certificate error, best thing is to have the certificate fixed ofcourse!
The XML editable
property is deprecated since API LEVEL 15.
You should use now the inputType
property with the value none
.
But there is a bug that makes this functionality useless.
Here you can follow the issue status.
It's not a nice solution but try it like this:
<table>
<tr>
<td>
<div>Lorem</div>
</td>
</tr>
<tr>
<td>
<div>Ipsum</div>
</td>
</tr>
</table>
and set the divs to the min-height:
div {
min-height: 300px;
}
Hope this is what you want ...
If you have the process ID (PID
) you can kill this process as follow:
Process processToKill = Process.GetProcessById(pid);
processToKill.Kill();
The whole idea behind Parallel.ForEach()
is that you have a set of threads and each thread processes part of the collection. As you noticed, this doesn't work with async
-await
, where you want to release the thread for the duration of the async call.
You could “fix” that by blocking the ForEach()
threads, but that defeats the whole point of async
-await
.
What you could do is to use TPL Dataflow instead of Parallel.ForEach()
, which supports asynchronous Task
s well.
Specifically, your code could be written using a TransformBlock
that transforms each id into a Customer
using the async
lambda. This block can be configured to execute in parallel. You would link that block to an ActionBlock
that writes each Customer
to the console.
After you set up the block network, you can Post()
each id to the TransformBlock
.
In code:
var ids = new List<string> { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10" };
var getCustomerBlock = new TransformBlock<string, Customer>(
async i =>
{
ICustomerRepo repo = new CustomerRepo();
return await repo.GetCustomer(i);
}, new ExecutionDataflowBlockOptions
{
MaxDegreeOfParallelism = DataflowBlockOptions.Unbounded
});
var writeCustomerBlock = new ActionBlock<Customer>(c => Console.WriteLine(c.ID));
getCustomerBlock.LinkTo(
writeCustomerBlock, new DataflowLinkOptions
{
PropagateCompletion = true
});
foreach (var id in ids)
getCustomerBlock.Post(id);
getCustomerBlock.Complete();
writeCustomerBlock.Completion.Wait();
Although you probably want to limit the parallelism of the TransformBlock
to some small constant. Also, you could limit the capacity of the TransformBlock
and add the items to it asynchronously using SendAsync()
, for example if the collection is too big.
As an added benefit when compared to your code (if it worked) is that the writing will start as soon as a single item is finished, and not wait until all of the processing is finished.

urllib3_logger = logging.getLogger('urllib3')
urllib3_logger.setLevel(logging.CRITICAL)
If you want to access event object as well as data passed, you have to pass event
and ticket.id
both as parameters, like following:
HTML
<input type="number" v-on:input="addToCart($event, ticket.id)" min="0" placeholder="0">
Javascript
methods: {
addToCart: function (event, id) {
// use event here as well as id
console.log('In addToCart')
console.log(id)
}
}
See working fiddle: https://jsfiddle.net/nee5nszL/
In case you are using vue-router, you may have to use $event in your v-on:input
method like following:
<input type="number" v-on:input="addToCart($event, num)" min="0" placeholder="0">
Here is working fiddle.
Change your Method as following and check it will work
private void initViews() {
inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.id_number_edit_text_custom, this, true);
View view = (View) inflater.inflate(R.layout.main, null);
editText = (EditText) view.findViewById(R.id.id_number_custom);
loadButton = (ImageButton) view.findViewById(R.id.load_data_button);
loadButton.setVisibility(RelativeLayout.INVISIBLE);
loadData();
}
Add a style with the attribute text-decoration:none;
:

CodeIgniter has some error logging functions built in.
$config['log_threshold'] = 1;
log_message('error', 'Some variable did not contain a value.');
log_exceptions()
. You can do this yourself or use this. More info on extending the core hereSee http://www.codeigniter.com/user_guide/general/errors.html
Update to the answer
// Get stack trace for the exception with source file information
var st = new StackTrace(ex, true);
// Get the top stack frame
var frame = st.GetFrame(st.FrameCount-1);
// Get the line number from the stack frame
var line = frame.GetFileLineNumber();
If you do "git status" while having a merge conflict, the first thing git shows you is how to abort the merge.
This case is valid for Debian.
Add the following to /etc/rc.local
/usr/bin/sudo -u {{user}} /usr/local/bin/forever start {{app path}}
{{user}}
replaces your username. {{app path}}
replaces your app path. For example, /var/www/test/app.js
You can now use fetch API/ It returns redirected: *boolean*
This one was amusing for others but less so for me. I had inherited the code (which was ASP) from a developer who had himself inherited it. The first programmer had created some very hard to understand code. The second developer had added a comment as follows (names hidden to protect the not-so-innocent):
'This code was written by **************.
'I haven't a clue what it does. He hasn't a clue what it does.
'Nobody else has a clue what it does or how it does it.
'It is something to do with data but **** knows what.
'The ******* still works so please do not change this code,
'even though it is a complete pile of ****.
So why didn't I find it amusing? Well, it was ASP code for a customer's intranet.
...and it was the customer who highlighted the comment to me.

Make sure that st_new.sh does something at the end what you can recognize (like touch /tmp/st_new.tmp when you remove the file first and always start one instance of st_new.sh).
Then make a polling loop. First sleep the normal time you think you should wait,
and wait short time in every loop.
This will result in something like
max_retry=20
retry=0
sleep 10 # Minimum time for st_new.sh to finish
while [ ${retry} -lt ${max_retry} ]; do
if [ -f /tmp/st_new.tmp ]; then
break # call results.sh outside loop
else
(( retry = retry + 1 ))
sleep 1
fi
done
if [ -f /tmp/st_new.tmp ]; then
source ../../results.sh
rm -f /tmp/st_new.tmp
else
echo Something wrong with st_new.sh
fi
Use the overloads that take the controller name too...
return RedirectToAction("Index", "MyController");
and
@Html.ActionLink("Link Name","Index", "MyController", null, null)
You can iterate DataTable
like this:
private void button1_Click(object sender, EventArgs e)
{
for(int i = 0; i< dt.Rows.Count;i++)
for (int j = 0; j <dt.Columns.Count ; j++)
{
object o = dt.Rows[i].ItemArray[j];
//if you want to get the string
//string s = o = dt.Rows[i].ItemArray[j].ToString();
}
}
Depending on the type of the data in the DataTable
cell, you can cast the object to whatever you want.

Use the arc4random_uniform(upper_bound)
function to generate a random number within a range. The following will generate a number between 0 and 73 inclusive.
arc4random_uniform(74)
arc4random_uniform(upper_bound)
avoids modulo bias as described in the man page:
arc4random_uniform() will return a uniformly distributed random number less than upper_bound. arc4random_uniform() is recommended over constructions like ``arc4random() % upper_bound'' as it avoids "modulo bias" when the upper bound is not a power of two.
This does it:
Do
c = c + 1
Loop While Cells(c, "A").Value <> ""
'prints the last empty row
Debug.Print c
If you're using chained syntax:
$(".class").each(function() {
// ...
});
...I don't think there's any (reasonable) way for the code within the each
function to know how many items there are. (Unreasonable ways would involve repeating the selector and using index
.)
But it's easy enough to make the collection available to the function that you're calling in each
. Here's one way to do that:
var collection = $(".class");
collection.each(function() {
// You can access `collection.length` here.
});
As a somewhat convoluted option, you could convert your jQuery object to an array and then use the array's forEach
. The arguments that get passed to forEach
's callback are the entry being visited (what jQuery gives you as this
and as the second argument), the index of that entry, and the array you called it on:
$(".class").get().forEach(function(entry, index, array) {
// Here, array.length is the total number of items
});
That assumes an at least vaguely modern JavaScript engine and/or a shim for Array#forEach
.
Or for that matter, give yourself a new tool:
// Loop through the jQuery set calling the callback:
// loop(callback, thisArg);
// Callback gets called with `this` set to `thisArg` unless `thisArg`
// is falsey, in which case `this` will be the element being visited.
// Arguments to callback are `element`, `index`, and `set`, where
// `element` is the element being visited, `index` is its index in the
// set, and `set` is the jQuery set `loop` was called on.
// Callback's return value is ignored unless it's `=== false`, in which case
// it stops the loop.
$.fn.loop = function(callback, thisArg) {
var me = this;
return this.each(function(index, element) {
return callback.call(thisArg || element, element, index, me);
});
};
Usage:
$(".class").loop(function(element, index, set) {
// Here, set.length is the length of the set
});
In MySQL -> INT(10) does not mean a 10-digit number, it means an integer with a display width of 10 digits. The maximum value for an INT in MySQL is 2147483647 (or 4294967295 if unsigned).
You can use a BIGINT instead of INT to store it as a numeric. Using BIGINT will save you 3 bytes per row over VARCHAR(10).
If you want to Store "Country + area + number separately". Try using a VARCHAR(20). This allows you the ability to store international phone numbers properly, should that need arise.
You can use -O-
(uppercase o) to redirect content to the stdout (standard output) or to a file (even special files like /dev/null
/dev/stderr
/dev/stdout
)
wget -O- http://yourdomain.com
Or:
wget -O- http://yourdomain.com > /dev/null
Or: (same result as last command)
wget -O/dev/null http://yourdomain.com
You're doing it the correct way but users may be providing urls to sites that have invalid SSL certs installed. You can ignore those cert problems if you put this line in before you make the actual web request:
ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);
where AcceptAllCertifications
is defined as
public bool AcceptAllCertifications(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certification, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
{
return true;
}
If anyone is still wondering what the value in CV_CAP_PROP_EXPOSURE
might be:
Depends. For my cheap webcam I have to enter the desired value directly, e.g. 0.1 for 1/10s. For my expensive industrial camera I have to enter -5 to get an exposure time of 2^-5s = 1/32s.
Just thought I would post something that I found quite useful and could be possible for someone who experiences similar needs.
The following method was a method I wrote for my JavaFX application to avoid having to cast and also avoid writing if object x instance of object b statements every time the controller was returned.
public <U> Optional<U> getController(Class<U> castKlazz){
try {
return Optional.of(fxmlLoader.<U>getController());
}catch (Exception e){
e.printStackTrace();
}
return Optional.empty();
}
The method declaration for obtaining the controller was
public <T> T getController()
By using type U passed into my method via the class object, it could be forwarded to the method get controller to tell it what type of object to return. An optional object is returned in case the wrong class is supplied and an exception occurs in which case an empty optional will be returned which we can check for.
This is what the final call to the method looked like (if present of the optional object returned takes a Consumer
getController(LoadController.class).ifPresent(controller->controller.onNotifyComplete());
Hi try this in eclipse: Window - Preferences - Android - SDK Location and setup SDK path.
It wraps around.
e.g:
public class Test {
public static void main(String[] args) {
int i = Integer.MAX_VALUE;
int j = Integer.MIN_VALUE;
System.out.println(i+1);
System.out.println(j-1);
}
}
prints
-2147483648
2147483647
In your HTML you have to use value = {{ old('') }}
. Without using it, you can't get the value back because what session will store in their cache.
Like for a name validation, this will be-
<input type="text" name="name" value="{{ old('name') }}" />
Now, you can get the value after submitting it if there is error with redirect.
return redirect()->back()->withInput();
As @infomaniac says, you can also use the Input class
directly,
return Redirect::back()->withInput(Input::all());
Add:
If you only show the specific field, then use $request->only()
return redirect()->back()->withInput($request->only('name'));
Hope, it might work in all case, thanks.
Please read this official blog entry on Google developer blog: http://android-developers.blogspot.be/2011/03/identifying-app-installations.html
Conclusion For the vast majority of applications, the requirement is to identify a particular installation, not a physical device. Fortunately, doing so is straightforward.
There are many good reasons for avoiding the attempt to identify a particular device. For those who want to try, the best approach is probably the use of ANDROID_ID on anything reasonably modern, with some fallback heuristics for legacy devices
.
call your (windows-)git with cygpath
as parameter, in order to convert the "calling path". I m confused why that should be a problem.
I haven't done any benchmarks, but this recipe "works for me".
The short version: use '%x' % val
, then unhexlify
the result. The devil is in the details, though, as unhexlify
requires an even number of hex digits, which %x
doesn't guarantee. See the docstring, and the liberal inline comments for details.

You can do base64 encoding and decoding with simple javascript.
$("input").keyup(function () {
var value = $(this).val(),
hash = Base64.encode(value);
$(".test").html(hash);
var decode = Base64.decode(hash);

WARNING: Long script ahead.
A while ago, I faced a similar problem: from a Tcl script, launch a number of processes, then wait for all of them to finish. Here is a demo script I wrote to solve this problem.
#!/usr/bin/env tclsh
# Launches many processes and wait for them to finish.
# This script will works on systems that has the ps command such as
# BSD, Linux, and OS X
package require Tclx; # For process-management utilities
proc updatePidList {stat} {
global pidList
global allFinished
# Parse the process ID of the just-finished process
lassign $stat processId howProcessEnded exitCode
# Remove this process ID from the list of process IDs
set pidList [lindex [intersect3 $pidList $processId] 0]
set processCount [llength $pidList]
# Occasionally, a child process quits but the signal was lost. This
# block of code will go through the list of remaining process IDs
# and remove those that has finished
set updatedPidList {}
foreach pid $pidList {
if {![catch {exec ps $pid} errmsg]} {
lappend updatedPidList $pid
}
}
set pidList $updatedPidList
# Show the remaining processes
if {$processCount > 0} {
puts "Waiting for [llength $pidList] processes"
} else {
set allFinished 1
puts "All finished"
}
}
# A signal handler that gets called when a child process finished.
# This handler needs to exit quickly, so it delegates the real works to
# the proc updatePidList
proc childTerminated {} {
# Restart the handler
signal -restart trap SIGCHLD childTerminated
# Update the list of process IDs
while {![catch {wait -nohang} stat] && $stat ne {}} {
after idle [list updatePidList $stat]
}
}

You can do it by javascript on client side or using some regex validator on the textbox.
script type="text/javascript" language="javascript">
function validateNumbersOnly(e) {
var unicode = e.charCode ? e.charCode : e.keyCode;
if ((unicode == 8) || (unicode == 9) || (unicode > 47 && unicode < 58)) {
return true;
}
else {
window.alert("This field accepts only Numbers");
return false;
}
}
</script>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator6" runat="server" Display="None" ErrorMessage="Accepts only numbers." ControlToValidate="TextBox1" ValidationExpression="^[0-9]*$" Text="*"></asp:RegularExpressionValidator>
Here's how to do with cv2 in Python:
# Create a blank 300x300 black image
image = np.zeros((300, 300, 3), np.uint8)
# Fill image with red color(set each pixel to red)
image[:] = (0, 0, 255)
Here's more complete example how to create new blank image filled with a certain RGB color
import cv2
import numpy as np
def create_blank(width, height, rgb_color=(0, 0, 0)):
"""Create new image(numpy array) filled with certain color in RGB"""
# Create black blank image
image = np.zeros((height, width, 3), np.uint8)
# Since OpenCV uses BGR, convert the color first
color = tuple(reversed(rgb_color))
# Fill image with color
image[:] = color
return image
# Create new blank 300x300 red image
width, height = 300, 300
red = (255, 0, 0)
image = create_blank(width, height, rgb_color=red)
cv2.imwrite('red.jpg', image)
As others have pointed out, params
values can come from the query string of a GET request, or the form data of a POST request, but there's also a third place they can come from: The path of the URL.
As you might know, Rails uses something called routes to direct requests to their corresponding controller actions. These routes may contain segments that are extracted from the URL and put into params
. For example, if you have a route like this:
match 'products/:id', ...
Then a request to a URL like http://example.com/products/42
will set params[:id]
to 42
.
I am able to get it working with the below command.
root@gitnew:# docker exec -it --user $(username) $(containername) /bin/bash
<td><input type="radio" name="gender" value="Male" id="male" <? if($gender=='Male')
{?> checked="" <? }?>/>Male
<input type="radio" name="gender" value="Female" id="female" <? if($gender=='Female') {?> checked="" <?}?>/>Female<br/> </td>
In iOS10 instead of your code, you should request an authorization for notification with the following: (Don't forget to add the UserNotifications
Framework)
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().requestAuthorization([.alert, .sound, .badge]) { (granted: Bool, error: NSError?) in
// Do something here
}
}
Also, the correct code for you is (use in the else
of the previous condition, for example):
let setting = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
UIApplication.shared().registerUserNotificationSettings(setting)
UIApplication.shared().registerForRemoteNotifications()
Finally, make sure Push Notification
is activated under target
-> Capabilities
-> Push notification
. (set it on On
)
