I use a combination of Tjeerd Visser's and porneL's answer.
class Something
{
private static $foo;
private static getFoo()
{
if ($foo === null)
$foo = [[ complicated initializer ]]
return $foo;
}
public static bar()
{
[[ do something with self::getFoo() ]]
}
}
But an even better solution is to do away with the static methods and use the Singleton pattern. Then you just do the complicated initialization in the constructor. Or make it a "service" and use DI to inject it into any class that needs it.
If you want to initialize some compound type (f.e. string) you can do something like that:
class SomeClass {
static std::list<string> _list;
public:
static const std::list<string>& getList() {
struct Initializer {
Initializer() {
// Here you may want to put mutex
_list.push_back("FIRST");
_list.push_back("SECOND");
....
}
}
static Initializer ListInitializationGuard;
return _list;
}
};
As the ListInitializationGuard
is a static variable inside SomeClass::getList()
method it will be constructed only once, which means that constructor is called once. This will initialize _list
variable to value you need. Any subsequent call to getList
will simply return already initialized _list
object.
Of course you have to access _list
object always by calling getList()
method.
use className->function(); instead className::function() ;
Try the below function :
function anchorify(text){
var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
var text1=text.replace(exp, "<a href='$1'>$1</a>");
var exp2 =/(^|[^\/])(www\.[\S]+(\b|$))/gim;
return text1.replace(exp2, '$1<a target="_blank" href="http://$2">$2</a>');
}
alert(anchorify("Hola amigo! https://www.sharda.ac.in/academics/"));
Rather than trying to address the resource as a File just ask the ClassLoader to return an InputStream for the resource instead via getResourceAsStream:
InputStream in = getClass().getResourceAsStream("/file.txt");
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
As long as the file.txt
resource is available on the classpath then this approach will work the same way regardless of whether the file.txt
resource is in a classes/
directory or inside a jar
.
The URI is not hierarchical
occurs because the URI for a resource within a jar file is going to look something like this: file:/example.jar!/file.txt
. You cannot read the entries within a jar
(a zip
file) like it was a plain old File.
This is explained well by the answers to:
I was only losing the session which was not a string or integer but a datarow. Putting the data in a serializable object and saving that into the session worked for me.
I was getting the same error.. i have done following

See http://git.or.cz/gitwiki/GitTips, section "How to compare two local repositories" in "General".
In short you are using GIT_ALTERNATE_OBJECT_DIRECTORIES environment variable to have access to object database of the other repository, and using git rev-parse with --git-dir
/ GIT_DIR to convert symbolic name in other repository to SHA-1 identifier.
Modern version would look something like this (assuming that you are in 'repo_a'):
GIT_ALTERNATE_OBJECT_DIRECTORIES=../repo_b/.git/objects \ git diff $(git --git-dir=../repo_b/.git rev-parse --verify HEAD) HEAD
where ../repo_b/.git
is path to object database in repo_b (it would be repo_b.git if it were bare repository). Of course you can compare arbitrary versions, not only HEADs.
Note that if repo_a and repo_b are the same repository, it might make more sense to put both of them in the same repository, either using "git remote add -f ...
" to create nickname(s) for repository for repeated updates, or obe off "git fetch ...
"; as described in other responses.
The java.net.URL
class is in fact not at all a good way of validating URLs. MalformedURLException
is not thrown on all malformed URLs during construction. Catching IOException
on java.net.URL#openConnection().connect()
does not validate URL either, only tell wether or not the connection can be established.
Consider this piece of code:
try {
new URL("http://.com");
new URL("http://com.");
new URL("http:// ");
new URL("ftp://::::@example.com");
} catch (MalformedURLException malformedURLException) {
malformedURLException.printStackTrace();
}
..which does not throw any exceptions.
I recommend using some validation API implemented using a context free grammar, or in very simplified validation just use regular expressions. However I need someone to suggest a superior or standard API for this, I only recently started searching for it myself.
Note
It has been suggested that URL#toURI()
in combination with handling of the exception java.net. URISyntaxException
can facilitate validation of URLs. However, this method only catches one of the very simple cases above.
The conclusion is that there is no standard java URL parser to validate URLs.
Yes, there is a way to emulate max-width
using a table, thus giving you both responsive and Outlook-friendly layout. What's more, this solution doesn't require conditional comments.
Suppose you want the equivalent of a centered div
with max-width
of 350px
. You create a table, set the width to 100%
. The table has three cells in a row. Set the width of the center TD
to 350
(using the HTML width
attribute, not CSS), and there you go.
If you want your content aligned left instead of centered, just leave out the first empty cell.
Example:
<table border="0" cellspacing="0" width="100%">
<tr>
<td></td>
<td width="350">The width of this cell should be a maximum of
350 pixels, but shrink to widths less than 350 pixels.
</td>
<td></td>
</tr>
</table>
In the jsfiddle I give the table a border so you can see what's going on, but obviously you wouldn't want one in real life:
def mergeSort(alist):
print("Splitting ",alist)
if len(alist)>1:
mid = len(alist)//2
lefthalf = alist[:mid]
righthalf = alist[mid:]
mergeSort(lefthalf)
mergeSort(righthalf)
i=0
j=0
k=0
while i < len(lefthalf) and j < len(righthalf):
if lefthalf[i] < righthalf[j]:
alist[k]=lefthalf[i]
i=i+1
else:
alist[k]=righthalf[j]
j=j+1
k=k+1
while i < len(lefthalf):
alist[k]=lefthalf[i]
i=i+1
k=k+1
while j < len(righthalf):
alist[k]=righthalf[j]
j=j+1
k=k+1
print("Merging ",alist)
alist = [54,26,93,17,77,31,44,55,20]
mergeSort(alist)
print(alist)
You can also use the <a>
label with javascript: void(0)
as href
value.
Example as follow:<a href="javascript: void(0)">+44 456 77 89 87</a>
If you have set public access for bucket and if it is still not working, edit bucker policy and paste following:
{

"s3:PutObjectAcl",
"s3:GetObject",
"s3:GetObjectAcl",
"s3:DeleteObject"

"Resource": [
"arn:aws:s3:::yourbucketnamehere",
"arn:aws:s3:::yourbucketnamehere/*"
],
"Effect": "Allow",
"Principal": "*"
}
]
}
A classic "or" would be |
. For example, ab|de
would match either side of the expression.
However, for something like your case you might want to use the ?
quantifier, which will match the previous expression exactly 0 or 1 times (1 times preferred; i.e. it's a "greedy" match). Another (probably more relyable) alternative would be using a custom character group:
\d+\s+[A-Z\s]+\s+[A-Z][A-Za-z]+
This pattern will match:
\d+
: One or more numbers.\s+
: One or more whitespaces.[A-Z\s]+
: One or more uppercase characters or space characters\s+
: One or more whitespaces.[A-Z][A-Za-z\s]+
: An uppercase character followed by at least one more character (uppercase or lowercase) or whitespaces.If you'd like a more static check, e.g. indeed only match ABC
and A ABC
, then you can combine a (non-matching) group and define the alternatives inside (to limit the scope):
\d (?:ABC|A ABC) Street
Or another alternative using a quantifier:
\d (?:A )?ABC Street
Agree with Jewes, XmlReader is the better way to go, especially if working with a larger XML document or processing multiple in a loop - no need to parse the entire document if you only need the document root.
Here's a simplified version, using XmlReader and MoveToContent().
http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.movetocontent.aspx
using (XmlReader xmlReader = XmlReader.Create(p_fileName))
{
if (xmlReader.MoveToContent() == XmlNodeType.Element)
rootNodeName = xmlReader.Name;
}
You need to install this extension to Visual Studio 2017/2019 in order to get access to the Installer Projects.
According to the page:
This extension provides the same functionality that currently exists in Visual Studio 2015 for Visual Studio Installer projects. To use this extension, you can either open the Extensions and Updates dialog, select the online node, and search for "Visual Studio Installer Projects Extension," or you can download directly from this page.
Once you have finished installing the extension and restarted Visual Studio, you will be able to open existing Visual Studio Installer projects, or create new ones.

If you're open to a Perl solution, here one similar to fedorqui's awk solution:
perl -F/ -lane 'print $F[-1]' input
-F/

I assume that each house is stored in its own table and has an 'id' field, e.g house id. So when you loop through the houses and display them, you could do something like this:
<a href="house.php?id=<?php echo $house_id;?>">
<?php echo $house_name;?>
</a>
Then in house.php, you would get the house id using $_GET['id']
, validate it using is_numeric()
and then display its info.

On the Mac you can store the passphrase for your private ssh key in your Keychain, which makes the use of it transparent. If you're logged in, it is available, when you are logged out your root user cannot use it. Removing the passphrase is a bad idea because anyone with the file can use it.
ssh-keygen -K

It evaluates to the left operand if the left operand is truthy, and the right operand otherwise.
In pseudocode,
foo = bar ?: baz;
roughly resolves to
foo = bar ? bar : baz;
or
if (bar) {
foo = bar;
} else {
foo = baz;
}
with the difference that bar
will only be evaluated once.
You can also use this to do a "self-check" of foo
as demonstrated in the code example you posted:
foo = foo ?: bar;
This will assign bar
to foo
if foo
is null or falsey, else it will leave foo
unchanged.
Some more examples:
<?php
var_dump(5 ?: 0); // 5
var_dump(false ?: 0); // 0
var_dump(null ?: 'foo'); // 'foo'
var_dump(true ?: 123); // true
var_dump('rock' ?: 'roll'); // 'rock'
?>

Above annotations worked well for me. I am using spring boot with JPA.
LDAP is also used to store your credentials in a network security system and retrieve it with your password and decrypted key giving you access to the services.
By value, what worked for me with jQuery 1.7 was the below code, try this:
$('#id option[value=theOptionValue]').prop('selected', 'selected').change();
I am using the same technique in a media query which effectively turns a bullet list into an inline list on smaller devices as they save space.
So the change from:
to:
List Item 1; List Item 2; List Item 3.
This error can also be the result of not having the line,

And to capture locale. You can do this:

Indeed, if you sorted out the iterator then buffering could now be your problem. You could tell the python in the sub-process not to buffer its output.
proc = subprocess.Popen(['python','fake_utility.py'],stdout=subprocess.PIPE)
becomes
proc = subprocess.Popen(['python','-u', 'fake_utility.py'],stdout=subprocess.PIPE)
I have needed this when calling python from within python.
With my testing of pandas
version 0.22.0
you can now answer this question easier with more readable code by simply using between
.
# create a single column DataFrame with dates going from Jan 1st 2018 to Jan 1st 2019
df = pd.DataFrame({'dates':pd.date_range('2018-01-01','2019-01-01')})
Let's say you want to grab the dates between Nov 27th 2018 and Jan 15th 2019:
# use the between statement to get a boolean mask
df['dates'].between('2018-11-27','2019-01-15', inclusive=False)
0 False
1 False
2 False
3 False
4 False
# you can pass this boolean mask straight to loc
df.loc[df['dates'].between('2018-11-27','2019-01-15', inclusive=False)]
dates
331 2018-11-28
332 2018-11-29
333 2018-11-30
334 2018-12-01
335 2018-12-02
Notice the inclusive argument. very helpful when you want to be explicit about your range. notice when set to True we return Nov 27th of 2018 as well:
df.loc[df['dates'].between('2018-11-27','2019-01-15', inclusive=True)]
dates
330 2018-11-27
331 2018-11-28
332 2018-11-29
333 2018-11-30
334 2018-12-01
This method is also faster than the previously mentioned isin
method:
%%timeit -n 5
df.loc[df['dates'].between('2018-11-27','2019-01-15', inclusive=True)]
868 µs ± 164 µs per loop (mean ± std. dev. of 7 runs, 5 loops each)
%%timeit -n 5
df.loc[df['dates'].isin(pd.date_range('2018-01-01','2019-01-01'))]
1.53 ms ± 305 µs per loop (mean ± std. dev. of 7 runs, 5 loops each)
However, it is not faster than the currently accepted answer, provided by unutbu, only if the mask is already created. but if the mask is dynamic and needs to be reassigned over and over, my method may be more efficient:
# already create the mask THEN time the function
start_date = dt.datetime(2018,11,27)
end_date = dt.datetime(2019,1,15)
mask = (df['dates'] > start_date) & (df['dates'] <= end_date)
%%timeit -n 5
df.loc[mask]
191 µs ± 28.5 µs per loop (mean ± std. dev. of 7 runs, 5 loops each)

The controller
function/object represents an abstraction model-view-controller (MVC). While there is nothing new to write about MVC, it is still the most significant advanatage of angular: split the concerns into smaller pieces. And that's it, nothing more, so if you need to react on Model
changes coming from View
the Controller
is the right person to do that job.
The story about link
function is different, it is coming from different perspective then MVC. And is really essential, once we want to cross the boundaries of a controller/model/view
(template).
Let' start with the parameters which are passed into the link
function:
function link(scope, element, attrs) {
To put the link
into the context, we should mention that all directives are going through this initialization process steps: Compile, Link. An Extract from Brad Green and Shyam Seshadri book Angular JS:
Compile phase (a sister of link, let's mention it here to get a clear picture):
In this phase, Angular walks the DOM to identify all the registered directives in the template. For each directive, it then transforms the DOM based on the directive’s rules (template, replace, transclude, and so on), and calls the compile function if it exists. The result is a compiled template function,
Link phase:
To make the view dynamic, Angular then runs a link function for each directive. The link functions typically creates listeners on the DOM or the model. These listeners keep the view and the model in sync at all times.
A nice example how to use the link
could be found here: Creating Custom Directives. See the example: Creating a Directive that Manipulates the DOM, which inserts a "date-time" into page, refreshed every second.
Just a very short snippet from that rich source above, showing the real manipulation with DOM. There is hooked function to $timeout service, and also it is cleared in its destructor call to avoid memory leaks
.directive('myCurrentTime', function($timeout, dateFilter) {
function link(scope, element, attrs) {
...
// the not MVC job must be done
function updateTime() {
element.text(dateFilter(new Date(), format)); // here we are manipulating the DOM
}
function scheduleUpdate() {
// save the timeoutId for canceling
timeoutId = $timeout(function() {
updateTime(); // update DOM
scheduleUpdate(); // schedule the next update
}, 1000);
}
element.on('$destroy', function() {
$timeout.cancel(timeoutId);
});

cleanText = strInputCode.replace(/<\/?[^>]+(>|$)/g, "");
Distilled from this website (web.achive).
This regex looks for <
, an optional slash /
, one or more characters that are not >
, then either >
or $
(the end of the line)
Examples:
'<div>Hello</div>' ==> 'Hello'
^^^^^ ^^^^^^
'Unterminated Tag <b' ==> 'Unterminated Tag '
^^
But it is not bulletproof:
'If you are < 13 you cannot register' ==> 'If you are '
^^^^^^^^^^^^^^^^^^^^^^^^
'<div data="score > 42">Hello</div>' ==> ' 42">Hello'
^^^^^^^^^^^^^^^^^^ ^^^^^^
If someone is trying to break your application, this regex will not protect you. It should only be used if you already know the format of your input. As other knowledgable and mostly sane people have pointed out, to safely strip tags, you must use a parser.
If you do not have acccess to a convenient parser like the DOM, and you cannot trust your input to be in the right format, you may be better off using a package like sanitize-html, and also other sanitizers are available.
Using Java 8 streams, you can turn your list into a stream and get the first item in a list using the .findFirst()
method.
List<String> stringsList = Arrays.asList("zordon", "alpha", "tommy");
Optional<String> optional = stringsList.stream().findFirst();
optional.get(); // "zordon"
The .findFirst()
method will return an Optional that may or may not contain a string value (it may not contain a value if the stringsList
is empty).
Then to unwrap the item from the Optional use the .get()
method.
you can use css to set the body tag to these settings:
body
{
padding:0px;
margin:0px;
width:100%;
height:100%;
}
You also can use
public boolean isDbConnected(Connection con) {
try {
return con != null && !con.isClosed();
} catch (SQLException ignored) {}
return false;
}
This could be solved without VBA by the following technique.
In this example I am counting all the threes (3) in the range A:A
of the sheets Page M904
, Page M905
and Page M906
.
List all the sheet names in a single continuous range like in the following example. Here listed in the range D3:D5
.
Then by having the lookup value in cell B2
, the result can be found in cell B4
by using the following formula:
=SUMPRODUCT(COUNTIF(INDIRECT("'"&D3:D5&"'!A:A"), B2))
This thread helped me a lot with my problem, but I've used $.queue in a different way and thought I would post what I came up with here. What I needed was a sequence of events (frames) to be triggered, but the sequence to be built dynamically. I have a variable number of placeholders, each of which should contain an animated sequence of images. The data is held in an array of arrays, so I loop through the arrays to build each sequence for each of the placeholders like this:
/* create an empty queue */
var theQueue = $({});
/* loop through the data array */
for (var i = 0; i < ph.length; i++) {
for (var l = 0; l < ph[i].length; l++) {
/* create a function which swaps an image, and calls the next function in the queue */
theQueue.queue("anim", new Function("cb", "$('ph_"+i+"' img').attr('src', '/images/"+i+"/"+l+".png');cb();"));
/* set the animation speed */
theQueue.delay(200,'anim');
}
}
/* start the animation */
theQueue.dequeue('anim');
This is a simplified version of the script I have arrived at, but should show the principle - when a function is added to the queue, it is added using the Function constructor - this way the function can be written dynamically using variables from the loop(s). Note the way the function is passed the argument for the next() call, and this is invoked at the end. The function in this case has no time dependency (it doesn't use $.fadeIn or anything like that), so I stagger the frames using $.delay.

I have the same problem with a footer I'm trying to divide up. I found that this worked for me by trying few of above suggestions combined:
footer div ul {
list-style-position: inside;
padding-left: 0;
}
This seems to keep it to the left under my h1 and the bullet points inside the div rather than outside to the left.
I had same issue. After browsing and struggling with issue found the below solution
import { HttpModule } from '@angular/http';
import { HttpClientModule } from '@angular/common/http';
imports: [
HttpModule,
HttpClientModule
]
Import HttpModule
and HttpClientModule
in app.module.ts and add into the imports like mentioned above.
Yes, each package must be defined in its own directory.
The source structure is defined in How to Write Go Code.
A package is a component that you can use in more than one program, that you can publish, import, get from an URL, etc. So it makes sense for it to have its own directory as much as a program can have a directory.
You can give https://github.com/ersiner/osx-env-sync a try. It handles both command line and GUI apps from a single source and works withe the latest version of OS X (Yosemite).
You can use path substitutions and other shell tricks since what you write is regular bash script to be sourced by bash in the first place. No restrictions.. (Check osx-env-sync documentation and you'll understand how it achieves this.)
I answered a similar question here where you'll find more.
You can make a div that has the same attributes as the <hr>
tag. This way it is fully able to be customized. Here is some sample code:

This demonstrates what could go below a custom hr.</p>

To see how the project turns out, here is a JSFiddle for the above code: http://jsfiddle.net/SplashHero/qmccsc06/1/
If the usage of something is part of the process of you making money, then it's generally considered a commercial use. If the purpose of the site is to, through some means or another, directly or indirectly, make you money, then it's probably commercial use.
If, on the other hand, something is merely incidental (not part of the process of production/working, but instead simply tacked on to the side), there are potential grounds for it not to be considered commercial use.
The selected answer is excellent, and I'm using it as well. However, if you're looking for a way to validate user date input, you should be aware that the Date object is very persistent about making what might appear to be invalid construction arguments into valid ones. The following unit test code illustrates the point:
QUnit.test( "valid date test", function( assert ) {
//The following are counter-examples showing how the Date object will
//wrangle several 'bad' dates into a valid date anyway
assert.equal(isValidDate(new Date(1980, 12, 15)), true);
d = new Date();
d.setFullYear(1980);
d.setMonth(1);
d.setDate(33);
assert.equal(isValidDate(d), true);
assert.equal(isValidDate(new Date(1980, 100, 150)), true);
//If you go to this exterme, then the checker will fail
assert.equal(isValidDate(new Date("This is junk")), false);
//This is a valid date string
assert.equal(isValidDate(new Date("November 17, 1989")), true);
//but is this?
assert.equal(isValidDate(new Date("November 35, 1989")), false);
//Ha! It's not. So, the secret to working with this version of
//isValidDate is to pass in dates as text strings... Hooboy
//alert(d.toString());
});
Updated for Apache 2.4, for non-systemd (e.g., CentOS 6.x, Amazon Linux AMI) and for systemd (e.g., CentOS 7.x):
There are two ways of having the apache process reload the configuration, depending on what you want done with its current threads, either advise to exit when idle, or killing them directly.
Note that Apache recommends using apachectl -k
as the command, and for systemd, the command is replaced by httpd -k
apachectl -k graceful
or httpd -k graceful
Apache will advise its threads to exit when idle, and then apache reloads the configuration (it doesn't exit itself), this means statistics are not reset.
apachectl -k restart
or httpd -k restart
This is similar to stop, in that the process kills off its threads, but then the process reloads the configuration file, rather than killing itself.
You should try this
import java.util.Scanner;
public class Time_converter {
public static void main(String[] args) {
Scanner input = new Scanner (System.in);
int seconds;
int minutes ;
int hours;
System.out.print("Enter the number of seconds : ");
seconds = input.nextInt();
hours = seconds / 3600;
minutes = (seconds%3600)/60;
int seconds_output = (seconds% 3600)%60;
System.out.println("The time entered in hours,minutes and seconds is:");
System.out.println(hours + " hours :" + minutes + " minutes:" + seconds_output +" seconds");
}
}
Python 3.6 now supports shorthand literal string interpolation with PEP 498. For your use case, the new syntax is simply:
f"({self.goals} goals, ${self.penalties})"
This is similar to the previous .format
standard, but lets one easily do things like:
>>> width = 10
>>> precision = 4
>>> value = decimal.Decimal('12.34567')
>>> f'result: {value:{width}.{precision}}'
'result: 12.35'
Make sure that the folder name does not contain .c extension. When I removed the .c extension in my folder name it worked automatically.
About the Implicit Objects of the Unified Expression Language, the Java EE 5 Tutorial writes:
Implicit Objects
The JSP expression language defines a set of implicit objects:
pageContext
: The context for the JSP page. Provides access to various objects including:
servletContext
: The context for the JSP page’s servlet and any web components contained in the same application. See Accessing the Web Context.session
: The session object for the client. See Maintaining Client State.request
: The request triggering the execution of the JSP page. See Getting Information from Requests.response
: The response returned by the JSP page. See Constructing Responses.- In addition, several implicit objects are available that allow easy access to the following objects:
param
: Maps a request parameter name to a single valueparamValues
: Maps a request parameter name to an array of valuesheader
: Maps a request header name to a single valueheaderValues
: Maps a request header name to an array of valuescookie
: Maps a cookie name to a single cookieinitParam
: Maps a context initialization parameter name to a single value- Finally, there are objects that allow access to the various scoped variables described in Using Scope Objects.
pageScope
: Maps page-scoped variable names to their valuesrequestScope
: Maps request-scoped variable names to their valuessessionScope
: Maps session-scoped variable names to their valuesapplicationScope
: Maps application-scoped variable names to their values
The interesting parts are in bold :)
So, to answer your question, you should be able to access it like this (using EL):
${param.accountID}
Or, using JSP Scriptlets (not recommended):
<%
String accountId = request.getParameter("accountID");
%>
Sometimes the Maven command line is sufficient when scripting something related to the project version, e.g. for artifact retrieval via URL from a repository:
mvn help:evaluate -Dexpression=project.version -q -DforceStdout
Usage example:
VERSION=$( mvn help:evaluate -Dexpression=project.version -q -DforceStdout )
ARTIFACT_ID=$( mvn help:evaluate -Dexpression=project.artifactId -q -DforceStdout )
GROUP_ID_URL=$( mvn help:evaluate -Dexpression=project.groupId -q -DforceStdout | sed -e 's#\.#/#g' )
curl -f -S -O http://REPO-URL/mvn-repos/${GROUP_ID_URL}/${ARTIFACT_ID}/${VERSION}/${ARTIFACT_ID}-${VERSION}.jar

You should first check the app version on the market and compare it with the version of the app on the device. If they are different, it may be an update available. In this post I wrote down the code for getting the current version of market and current version on the device and compare them together. I also showed how to show the update dialog and redirect the user to the update page. Please visit this link: https://stackoverflow.com/a/33925032/5475941
I had the same problem with the certificates error and was because of SNI, and http client that I used didn't had SNI implemented. So an version update did the job

When I'm working with csv
files, I often use the pandas library. It makes things like this very easy. For example:
import pandas as pd
a = pd.read_csv("filea.csv")
b = pd.read_csv("fileb.csv")
b = b.dropna(axis=1)
merged = a.merge(b, on='title')
merged.to_csv("output.csv", index=False)
Some explanation follows. First, we read in the csv files:
>>> a = pd.read_csv("filea.csv")
>>> b = pd.read_csv("fileb.csv")
>>> a
title stage jan feb
0 darn 3.001 0.421 0.532
1 ok 2.829 1.036 0.751
2 three 1.115 1.146 2.921
>>> b
title mar apr may jun Unnamed: 5
0 darn 0.631 1.321 0.951 1.7510 NaN
1 ok 1.001 0.247 2.456 0.3216 NaN
2 three 0.285 1.283 0.924 956.0000 NaN
and we see there's an extra column of data (note that the first line of fileb.csv
-- title,mar,apr,may,jun,
-- has an extra comma at the end). We can get rid of that easily enough:
>>> b = b.dropna(axis=1)
>>> b
title mar apr may jun
0 darn 0.631 1.321 0.951 1.7510
1 ok 1.001 0.247 2.456 0.3216
2 three 0.285 1.283 0.924 956.0000
Now we can merge a
and b
on the title column:
>>> merged = a.merge(b, on='title')
>>> merged
title stage jan feb mar apr may jun
0 darn 3.001 0.421 0.532 0.631 1.321 0.951 1.7510

2 three 1.115 1.146 2.921 0.285 1.283 0.924 956.0000
and finally write this out:
>>> merged.to_csv("output.csv", index=False)
producing:
title,stage,jan,feb,mar,apr,may,jun
darn,3.001,0.421,0.532,0.631,1.321,0.951,1.751

Just check for the current Facebook user id $user
and if it returned null then you need to reauthorize the user (or use the custom $_SESSION
user id value - not recommended)
require 'facebook/src/facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'APP_ID',
'secret' => 'APP_SECRET',
));
$user = $facebook->getUser();
$photo_details = array('message' => 'my place');
$file='photos/my.jpg'; //Example image file
$photo_details['image'] = '@' . realpath($file);
if ($user) {
try {
// We have a valid FB session, so we can use 'me'
$upload_photo = $facebook->api('/me/photos', 'post', $photo_details);
} catch (FacebookApiException $e) {
error_log($e);
}
}
// login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
// redirect to Facebook login to get a fresh user access_token
$loginUrl = $facebook->getLoginUrl();
header('Location: ' . $loginUrl);
}

Just had this issue but had to find the config for IIS Express so I could add the mime types. For me, it was located at C:\Users\<username>\Documents\IISExpress\config\applicationhost.config
and I was able to add in the correct "mime map" there.
Even if fileno(FILE *)
may return a file descriptor, be VERY careful not to bypass stdio's buffer. If there is buffer data (either read or unflushed write), reads/writes from the file descriptor might give you unexpected results.
To answer one of the side questions, to convert a file descriptor to a FILE pointer, use fdopen(3)
The constructor is called only once, so you can safely do what you want, however the disadvantage of calling methods from within the constructor, rather than directly, is that you don't get direct feedback if the method fails. This gets more difficult the more methods you call.
One solution is to provide methods that you can call to query the 'health' of the object once it's been constructed. For example the method isConfigOK()
can be used to see if the config read operation was OK.
Another solution is to throw exceptions in the constructor upon failure, but it really depends on how 'fatal' these failures are.
class A
{
Map <String,String> config = null;
public A()
{
readConfig();
}
protected boolean readConfig()
{
...
}
public boolean isConfigOK()
{
// Check config here
return true;
}
};
This issue occurs when someone has commited the code to develop/master and latest code has not been rebased from develop/master and you're trying to overwrite new changes to develop/master branch
Solution:
I'm seeing this in a VS2017 environment. My build script calls VsDevCmd.bat
first, and to solve this problem I set the VCTargetsPath
environment variable after VsDevCmd
and before calling MSBuild:
set VCTargetsPath=%VCIDEInstallDir%VCTargets
It seems arbitrary to me because I don't know how you would get the number as any type, but what about checking Abs(number) != number? Maybe && number != 0
In JDK1.8 you can use aggregate operations and a lambda expression:
String[] strArray = new String[] {"John", "Mary", "Bob"};
// #1
Arrays.asList(strArray).stream().forEach(s -> System.out.println(s));
// #2
Stream.of(strArray).forEach(System.out::println);
// #3
Arrays.stream(strArray).forEach(System.out::println);
/* output:
John
Mary
Bob
*/
Also, starting with Java 8, one could also take advantage of the join() method provided by the String class to print out array elements, without the brackets, and separated by a delimiter of choice (which is the space character for the example shown below)
string[] greeting = {"Hey", "there", "amigo!"};
String delimiter = " ";
String.join(delimiter, greeting)
` The output will be "Hey there amigo!"
Chart.js has a bug:
Chart.controller(instance)
registers any new chart in a global property Chart.instances[]
and deletes it from this property on .destroy()
.
But at chart creation Chart.js also writes ._meta
property to dataset variable:
var meta = dataset._meta[me.id];
if (!meta) {
meta = dataset._meta[me.id] = {
type: null,
data: [],
dataset: null,
controller: null,
hidden: null, // See isDatasetVisible() comment
xAxisID: null,
yAxisID: null
};
and it doesn't delete this property on destroy()
.
If you use your old dataset object without removing ._meta property
, Chart.js will add new dataset to ._meta
without deletion previous data. Thus, at each chart's re-initialization your dataset object accumulates all previous data.
In order to avoid this, destroy dataset object after calling Chart.destroy()
.
On windows 10, I faced the same error - only Anaconda Prompt was showing in the startup menu. What I did is i re-installed Anaconda and selected install for all users of the pc (in my initial installation I have installed only for current user).
Nicely explained above!
For all those who may suffer like me to get this working in a localized Windows (mine is XP in Slovak), you may try to replace the %
with a !
So:
SET TEXT=Hello World
SET SUBSTRING=!TEXT:~3,5!
ECHO !SUBSTRING!
i use this:
for (Map.Entry<Object, Object> entry:properties.entrySet()) {
map.put((String) entry.getKey(), (String) entry.getValue());
}
Here's an example where I found the replace( ) function helpful for giving me insight. The problem required a long integer vector be changed into a character vector and with its integers replaced by given character values.
## figuring out replace( )
(test <- c(rep(1,3),rep(2,2),rep(3,1)))
which looks like
[1] 1 1 1 2 2 3
and I want to replace every 1 with an A and 2 with a B and 3 with a C
letts <- c("A","B","C")
so in my own secret little "dirty-verse" I used a loop
for(i in 1:3)
{test <- replace(test,test==i,letts[i])}
which did what I wanted
test
[1] "A" "A" "A" "B" "B" "C"
In the first sentence I purposefully left out that the real objective was to make the big vector of integers a factor vector and assign the integer values (levels) some names (labels).
So another way of doing the replace( ) application here would be
(test <- factor(test,labels=letts))
[1] A A A B B C
Levels: A B C
function deleteEmpty(obj){
for(var k in obj)
if(k == "children"){
if(obj[k]){
deleteEmpty(obj[k]);
}else{
delete obj.children;
}
}
}
for(var i=0; i< a.children.length; i++){
deleteEmpty(a.children[i])
}

Note: this answer was motivated by this comment. The purpose of UsedRange
is different from what is mentioned in the answer above.
As to the correct way of finding the last used cell, one has first to decide what is considered used, and then select a suitable method. I conceive at least three meanings:
Used = non-blank, i.e., having data.
Used = "... in use, meaning the section that contains data or formatting." As per official documentation, this is the criterion used by Excel at the time of saving. See also this official documentation. If one is not aware of this, the criterion may produce unexpected results, but it may also be intentionally exploited (less often, surely), e.g., to highlight or print specific regions, which may eventually have no data. And, of course, it is desirable as a criterion for the range to use when saving a workbook, lest losing part of one's work.
Used = "... in use, meaning the section that contains data or formatting" or conditional formatting. Same as 2., but also including cells that are the target for any Conditional Formatting rule.
How to find the last used cell depends on what you want (your criterion).
For criterion 1, I suggest reading this answer.
Note that UsedRange
is cited as unreliable. I think that is misleading (i.e., "unfair" to UsedRange
), as UsedRange
is simply not meant to report the last cell containing data. So it should not be used in this case, as indicated in that answer. See also this comment.
For criterion 2, UsedRange
is the most reliable option, as compared to other options also designed for this use. It even makes it unnecessary to save a workbook to make sure that the last cell is updated.
Ctrl+End will go to a wrong cell prior to saving
(“The last cell is not reset until you save the worksheet”, from
http://msdn.microsoft.com/en-us/library/aa139976%28v=office.10%29.aspx.
It is an old reference, but in this respect valid).
For criterion 3, I do not know any built-in method.
Criterion 2 does not account for Conditional Formatting. One may have formatted cells, based on formulas, which are not detected by UsedRange
or Ctrl+End.
In the figure, the last cell is B3, since formatting was applied explicitly to it. Cells B6:D7 have a format derived from a Conditional Formatting rule, and this is not detected even by UsedRange
.
Accounting for this would require some VBA programming.
As to your specific question: What's the reason behind this?
Your code uses the first cell in your range E4:E48 as a trampoline, for jumping down with End(xlDown)
.
The "erroneous" output will obtain if there are no non-blank cells in your range other than perhaps the first. Then, you are leaping in the dark, i.e., down the worksheet (you should note the difference between blank and empty string!).
Note that:
If your range contains non-contiguous non-blank cells, then it will also give a wrong result.
If there is only one non-blank cell, but it is not the first one, your code will still give you the correct result.
This is an adaptation of the answer from Andy E.
This will do a task e.g. refresh the page every 30 seconds, but only if the page is visible and focused.
If visibility can't be detected, then only focus will be used.
If the user focuses the page, then it will update immediately

if you want to use only arraylist then I am worried there is no better way which will create a huge performance benefit. But by only using arraylist i would check before adding into the list like following
void addToList(String s){
if(!yourList.contains(s))
yourList.add(s);
}
In this cases using a Set is suitable.
The following code should be considered bad form, regardless of language or desired functionality:
while( true ) {
}
The while( true )
loop is poor form because it:
while(true)
for loops that are not infinite, we lose the ability to concisely communicate when loops actually have no terminating condition. (Arguably, this has already happened, so the point is moot.)The following code is better form:
while( isValidState() ) {
execute();
}
bool isValidState() {
return msg->state != DONE;
}
No flag. No goto
. No exception. Easy to change. Easy to read. Easy to fix. Additionally the code:
The second point is important. Without knowing how the code works, if someone asked me to make the main loop let other threads (or processes) have some CPU time, two solutions come to mind:
Readily insert the pause:
while( isValidState() ) {
execute();
sleep();
}
Override execute:
void execute() {
super->execute();
sleep();
}
This code is simpler (thus easier to read) than a loop with an embedded switch
. The isValidState
method should only determine if the loop should continue. The workhorse of the method should be abstracted into the execute
method, which allows subclasses to override the default behaviour (a difficult task using an embedded switch
and goto
).
Contrast the following answer (to a Python question) that was posted on StackOverflow:
while True:
choice = raw_input('What do you want? ')
if choice == 'restart':
continue
else:
break
print 'Break!'
Versus:
choice = 'restart';
while choice == 'restart':
choice = raw_input('What do you want? ')
print 'Break!'
Here, while True
results in misleading and overly complex code.
Use the cdecl program, as suggested by K&R.
$ cdecl
Type `help' or `?' for help
cdecl> explain int* arr1[8];
declare arr1 as array 8 of pointer to int
cdecl> explain int (*arr2)[8]
declare arr2 as pointer to array 8 of int
cdecl> explain int *(arr3[8])
declare arr3 as array 8 of pointer to int
cdecl>
It works the other way too.
cdecl> declare x as pointer to function(void) returning pointer to float

The json.dumps method can accept an optional parameter called default which is expected to be a function. Every time JSON tries to convert a value it does not know how to convert it will call the function we passed to it. The function will receive the object in question, and it is expected to return the JSON representation of the object.
def myconverter(o):
if isinstance(o, datetime.datetime):
return o.__str__()
print(json.dumps(d, default = myconverter))
Since WordPress already uses jQuery you can try something like this:
var POST=<?php echo json_encode($_POST); ?>;
for(k in POST){
$("#"+k).val(POST[k]);
}
You can use reduce()
without any regex:
(str, n) => {
return str.split('').reduce(
(acc, rec, index) => {
return ((index % n) || !(index)) ? acc.concat(rec) : acc.concat(',', rec)
},
''
).split(',')
}
I faced this error (errno 121) but it was caused by mysql-created intermediate tables that had been orphaned, preventing me from altering a table even though no such constraint name existed across any of my tables. At some point, my MySQL had crashed or failed to cleanup an intermediate table (table name starting with a #sql-) which ended up presenting me with an error such as: Can't create table '#sql-' (errno 121) when trying to run an ALTER TABLE with certain constraint names.
According to the docs at http://dev.mysql.com/doc/refman/5.7/en/innodb-troubleshooting-datadict.html , you can search for these orphan tables with:
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_TABLES WHERE NAME LIKE '%#sql%';
The version I was working with was 5.1, but the above command only works on versions >= 5.6 (manual is incorrect about it working for 5.5 or earlier, because INNODB_SYS_TABLES does not exist in such versions). I was able to find the orphaned temporary table (which did not match the one named in the message) by searching my mysql data directory in command line:
find . -iname '#*'
After discovering the filename, such as #sql-9ad_15.frm, I was able to drop that orphaned table in MySQL:
USE myschema;
DROP TABLE `#mysql50##sql-9ad_15`;
After doing so, I was then able to successfully run my ALTER TABLE.
For completeness, as per the MySQL documentation linked, "the #mysql50# prefix tells MySQL to ignore file name safe encoding introduced in MySQL 5.1."

background:
${parameter/pattern/string} Pattern substitution. The pattern is expanded to produce a pat tern just as in pathname expansion. Parameter is expanded and the longest match of pattern against its value is replaced with string. If pattern begins with /, all matches of pattern are replaced with string. Normally only the first match is replaced. If pattern begins with #, it must match at the begin- ning of the expanded value of parameter. If pattern begins with %, it must match at the end of the expanded value of parameter. If string is null, matches of pattern are deleted and the / fol lowing pattern may be omitted. If parameter is @ or *, the sub stitution operation is applied to each positional parameter in turn, and the expansion is the resultant list. If parameter is an array variable subscripted with @ or *, the substitution operation is applied to each member of the array in turn, and the expansion is the resultant list.
If the extglob shell option is enabled using the shopt builtin, several extended pattern matching operators are recognized. In the following description, a pattern-list is a list of one or more patterns separated by a |. Composite patterns may be formed using one or more of the fol lowing sub-patterns: ?(pattern-list) Matches zero or one occurrence of the given patterns *(pattern-list) Matches zero or more occurrences of the given patterns +(pattern-list) Matches one or more occurrences of the given patterns @(pattern-list) Matches one of the given patterns !(pattern-list) Matches anything except one of the given patterns

I had a similar issue and ended up with this:
For me this has the advantage that data and annotation are not overlapping.
from matplotlib import pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.add_subplot(111)
A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54
plt.plot(A,B)
# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
x = A[ind]
y = B[ind]
xPos = x1 + .02 * (x1 - x0)
yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
ax.annotate('',#label,
xy=(x, y), xycoords='data',
xytext=(xPos, yPos), textcoords='data',
arrowprops=dict(
connectionstyle="arc3,rad=0.",
shrinkA=0, shrinkB=10,
arrowstyle= '-|>', ls= '-', linewidth=2
),
va='bottom', ha='left', zorder=19
)
ax.text(xPos + .01 * (x1 - x0), yPos,
'({:.2f}, {:.2f})'.format(x,y),
transform=ax.transData, va='center')
plt.grid()
plt.show()
Using the text argument in .annotate
ended up with unfavorable text positions.
Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.
If you try to enter a negative number, the onkeyup event blocks this and if you use the arrow on the input number, the onblur event resolves that part.
<input type="number" _x000D_
onkeyup="if(this.value<0)this.value=1"_x000D_
onblur="if(this.value<0)this.value=1"_x000D_
>
_x000D_
I realize this is an old question, but I use a much simpler way. Typically I just grab the list that I need, either by query or copying an existing list or whatever, then remove the duplicates. We will assume for this answer that your list is already in column C, row 4, as per the original question. This method works for whatever size list you have and you can select header yes or no.
Dim rng as range
Range("C4").Select
Set rng = Range(Selection, Selection.End(xlDown))
rng.RemoveDuplicates Columns:=1, Header:=xlYes
The methods in the other answers will not work properly when the yticks are large. The ylabel will either overlap with ticks, be clipped on the left or completely invisible/outside of the figure.
I've modified Hagne's answer so it works with more than 1 column of subplots, for both xlabel and ylabel, and it shifts the plot to keep the ylabel visible in the figure.
def set_shared_ylabel(a, xlabel, ylabel, labelpad = 0.01, figleftpad=0.05):
"""Set a y label shared by multiple axes
Parameters
----------
a: list of axes
ylabel: string
labelpad: float
Sets the padding between ticklabels and axis label"""
f = a[0,0].get_figure()
f.canvas.draw() #sets f.canvas.renderer needed below
# get the center position for all plots
top = a[0,0].get_position().y1
bottom = a[-1,-1].get_position().y0
# get the coordinates of the left side of the tick labels
x0 = 1
x1 = 1
for at_row in a:
at = at_row[0]
at.set_ylabel('') # just to make sure we don't and up with multiple labels
bboxes, _ = at.yaxis.get_ticklabel_extents(f.canvas.renderer)
bboxes = bboxes.inverse_transformed(f.transFigure)
xt = bboxes.x0
if xt < x0:
x0 = xt
x1 = bboxes.x1
tick_label_left = x0
# shrink plot on left to prevent ylabel clipping
# (x1 - tick_label_left) is the x coordinate of right end of tick label,
# basically how much padding is needed to fit tick labels in the figure
# figleftpad is additional padding to fit the ylabel
plt.subplots_adjust(left=(x1 - tick_label_left) + figleftpad)
# set position of label,
# note that (figleftpad-labelpad) refers to the middle of the ylabel
a[-1,-1].set_ylabel(ylabel)
a[-1,-1].yaxis.set_label_coords(figleftpad-labelpad,(bottom + top)/2, transform=f.transFigure)
# set xlabel
y0 = 1
for at in axes[-1]:
at.set_xlabel('') # just to make sure we don't and up with multiple labels
bboxes, _ = at.xaxis.get_ticklabel_extents(fig.canvas.renderer)
bboxes = bboxes.inverse_transformed(fig.transFigure)
yt = bboxes.y0
if yt < y0:
y0 = yt
tick_label_bottom = y0
axes[-1, -1].set_xlabel(xlabel)
axes[-1, -1].xaxis.set_label_coords((left + right) / 2, tick_label_bottom - labelpad, transform=fig.transFigure)
It works for the following example, while Hagne's answer won't draw ylabel (since it's outside of the canvas) and KYC's ylabel overlaps with the tick labels:
import matplotlib.pyplot as plt
import itertools
fig, axes = plt.subplots(3, 4, sharey='row', sharex=True, squeeze=False)
fig.subplots_adjust(hspace=.5)
for i, a in enumerate(itertools.chain(*axes)):
a.plot([0,4**i], [0,4**i])
a.set_title(i)
set_shared_ylabel(axes, 'common X', 'common Y')
plt.show()
Alternatively, if you are fine with colorless axis, I've modified Julian Chen's solution so ylabel won't overlap with tick labels.
Basically, we just have to set ylims of the colorless so it matches the largest ylims of the subplots so the colorless tick labels sets the correct location for the ylabel.
Again, we have to shrink the plot to prevent clipping. Here I've hard coded the amount to shrink, but you can play around to find a number that works for you or calculate it like in the method above.
import matplotlib.pyplot as plt
import itertools
fig, axes = plt.subplots(3, 4, sharey='row', sharex=True, squeeze=False)
fig.subplots_adjust(hspace=.5)
miny = maxy = 0
for i, a in enumerate(itertools.chain(*axes)):
a.plot([0,4**i], [0,4**i])
a.set_title(i)
miny = min(miny, a.get_ylim()[0])
maxy = max(maxy, a.get_ylim()[1])
# add a big axes, hide frame
# set ylim to match the largest range of any subplot
ax_invis = fig.add_subplot(111, frameon=False)
ax_invis.set_ylim([miny, maxy])
# hide tick and tick label of the big axis
plt.tick_params(labelcolor='none', top=False, bottom=False, left=False, right=False)
plt.xlabel("common X")
plt.ylabel("common Y")
# shrink plot to prevent clipping
plt.subplots_adjust(left=0.15)
plt.show()

In case anyone's curious, the ultimate reason is that HTML was originally a dialect of SGML, which is XML's weird older brother. In SGML-land, elements can be specified in the DTD as either self-closing (e.g. BR, HR, INPUT), implicitly closeable (e.g. P, LI, TD), or explicitly closeable (e.g. TABLE, DIV, SCRIPT). XML, of course, has no concept of this.
The tag-soup parsers used by modern browsers evolved out of this legacy, although their parsing model isn't pure SGML anymore. And of course, your carefully-crafted XHTML is being treated as badly-written SGML-inspired tag-soup unless you send it with an XML mime type. This is also why...
<p><div>hello</div></p>
...gets interpreted by the browser as:
<p></p><div>hello</div><p></p>
...which is the recipe for a lovely obscure bug that can throw you into fits as you try to code against the DOM.

The answer to the above question is "none of the above". When you download new STS it won't support the old Spring Boot parent version. Just update parent version with latest comes with STS it will work.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.8.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
If you have problem getting the latest, just create a new Spring Starter Project. Go to File->New->Spring Start Project and create a demo project you will get the latest parent version, change your version with that all will work. I do this every time I change STS.
Use:
$path = "C:\temp\"
If (!(test-path $path))
{
md C:\Temp\
}
The first line creates a variable named $path
and assigns it the string value of "C:\temp\"
The second line is an If
statement which relies on the Test-Path cmdlet to check if the variable $path
does not exist. The not exists is qualified using the !
symbol.
Third line: If the path stored in the string above is not found, the code between the curly brackets will be run.
md
is the short version of typing out: New-Item -ItemType Directory -Path $path
Note: I have not tested using the -Force
parameter with the below to see if there is undesirable behavior if the path already exists.
New-Item -ItemType Directory -Path $path
Kbrose's guidance on finding which logger was generating log messages was immensely useful. For my Django project, I had to sort through 120 different loggers until I found that it was the elasticsearch

...
'elasticsearch': {
'handlers': ['console'],
'level': logging.WARNING,
},

Posting here in case someone else is seeing the unhelpful log messages come through whenever they run an Elasticsearch query.

If you're not sure your input is going to be a Numpy array, you can use asarray
with dtype=int
instead of astype
:
>>> np.asarray([1,2,3,4], dtype=int)
array([1, 2, 3, 4])
If the input array already has the correct dtype, asarray
avoids the array copy while astype
does not (unless you specify copy=False
):
>>> a = np.array([1,2,3,4])
>>> a is np.asarray(a) # no copy :)
True
>>> a is a.astype(int) # copy :(
False
>>> a is a.astype(int, copy=False) # no copy :)
True

Judging from other answers, no one except @rob-kennedy talked about the call_args_list
.
It's a powerful tool for that you can implement the exact contrary of MagicMock.assert_called_with()
call_args_list
is a list of call
objects. Each call
object represents a call made on a mocked callable.
>>> from unittest.mock import MagicMock
>>> m = MagicMock()
>>> m.call_args_list
[]
>>> m(42)
<MagicMock name='mock()' id='139675158423872'>
>>> m.call_args_list
[call(42)]
>>> m(42, 30)
<MagicMock name='mock()' id='139675158423872'>
>>> m.call_args_list
[call(42), call(42, 30)]
Consuming a call
object is easy, since you can compare it with a tuple of length 2 where the first component is a tuple containing all the positional arguments of the related call, while the second component is a dictionary of the keyword arguments.
>>> ((42,),) in m.call_args_list
True
>>> m(42, foo='bar')
<MagicMock name='mock()' id='139675158423872'>
>>> ((42,), {'foo': 'bar'}) in m.call_args_list
True
>>> m(foo='bar')
<MagicMock name='mock()' id='139675158423872'>
>>> ((), {'foo': 'bar'}) in m.call_args_list
True
So, a way to address the specific problem of the OP is
def test_something():
with patch('something') as my_var:
assert ((some, args),) not in my_var.call_args_list
Note that this way, instead of just checking if a mocked callable has been called, via MagicMock.called
, you can now check if it has been called with a specific set of arguments.
That's useful. Say you want to test a function that takes a list and call another function, compute()
, for each of the value of the list only if they satisfy a specific condition.
You can now mock compute
, and test if it has been called on some value but not on others.
Here's the other one, particularly useful to convert the multiple columns to string instead of just single column:
In [76]: import numpy as np
In [77]: import pandas as pd
In [78]: df = pd.DataFrame({
...: 'A': [20, 30.0, np.nan],
...: 'B': ["a45a", "a3", "b1"],
...: 'C': [10, 5, np.nan]})
...:
In [79]: df.dtypes ## Current datatype
Out[79]:
A float64
B object
C float64
dtype: object
## Multiple columns string conversion
In [80]: df[["A", "C"]] = df[["A", "C"]].astype(str)
In [81]: df.dtypes ## Updated datatype after string conversion
Out[81]:
A object
B object
C object
dtype: object

Haider's answer is correct for pre-iOS 6. However, as of iOS 6 viewDidUnload and viewWillUnload are never called. The docs state: "Views are no longer purged under low-memory conditions and so this method is never called."
You can solve this with a one-liner( errStringified ) in plain javascript:
var error = new Error('simple error message');
var errStringified = (err => JSON.stringify(Object.getOwnPropertyNames(Object.getPrototypeOf(err)).reduce(function(accumulator, currentValue) { return accumulator[currentValue] = err[currentValue], accumulator}, {})))(error);
console.log(errStringified);
It works with DOMExceptions as well.
iWasRobbed's answer is great, except there is an AVCaptureSession running in the background all the time. On my iPhone 4s it takes about 12% CPU power according to Instrument so my app took about 1% battery in a minute. In other words if the device is prepared for AV capture it's not cheap.
Using the code below my app requires 0.187% a minute so the battery life is more than 5x longer.
This code works just fine on any device (tested on both 3GS (no flash) and 4s). Tested on 4.3 in simulator as well.
#import <AVFoundation/AVFoundation.h>
- (void) turnTorchOn:(BOOL)on {
Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
if (captureDeviceClass != nil) {

} else {

I guess there are so many ways to make what you want. Here's a way that I use. With the commons.io
library you can iterate over the files in a directory. You must use the FileUtils.iterateFiles
method and you can process each file.
You can find the information here: http://commons.apache.org/proper/commons-io/download_io.cgi
Here's an example:
Iterator it = FileUtils.iterateFiles(new File("C:/"), null, false);
while(it.hasNext()){
System.out.println(((File) it.next()).getName());
}
You can change null
and put a list of extentions if you wanna filter. Example: {".xml",".java"}
Questions from the top of my head since that time I gone crazy with jacoco.
Yes. You have to use jacoco agent that runs in mode output=tcpserver
, jacoco ant lib. Basically two jar
s. This will give you 99% success.
You append a string
-javaagent:[your_path]/jacocoagent.jar=destfile=/jacoco.exec,output=tcpserver,address=*
to your application server JAVA_OPTS and restart it. In this string only [your_path]
have to be replaced with the path to jacocoagent.jar, stored(store it!) on your VM where app server runs. Since that time you start app server, all applications that are deployed will be dynamically monitored and their activity (meaning code usage) will be ready for you to get in jacocos .exec format by tcl request.
Yes, for that purpose you need jacocoant.jar and ant build script located in your jenkins workspace.
That's right.
That's not right, jacoco maven plugin can collect unit test data and some integration tests data(see Arquillian Jacoco), but if you have for example rest assured tests as a separated build in jenkins, and want to show multi-module coverage, I can't see how maven plugin can help you.
Only coverage data in .exec
format. Sonar then can read it.
No, sonar does, but not jacoco. When you do mvn sonar:sonar
path to classes comes into play.
It has to be presented in your jenkins workspace. Mine ant script, I called it jacoco.xml
looks like that:
<project name="Jacoco library to collect code coverage remotely" xmlns:jacoco="antlib:org.jacoco.ant">
<property name="jacoco.port" value="6300"/>
<property name="jacocoReportFile" location="${workspace}/it-jacoco.exec"/>
<taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml">
<classpath path="${workspace}/tools/jacoco/jacocoant.jar"/>
</taskdef>
<target name="jacocoReport">
<jacoco:dump address="${jacoco.host}" port="${jacoco.port}" dump="true" reset="true" destfile="${jacocoReportFile}" append="false"/>
</target>
<target name="jacocoReset">
<jacoco:dump address="${jacoco.host}" port="${jacoco.port}" reset="true" destfile="${jacocoReportFile}" append="false"/>
<delete file="${jacocoReportFile}"/>
</target>
</project>
Two mandatory params you should pass when invoking this script
-Dworkspace=$WORKSPACE
use it to point to your jenkins workspace and -Djacoco.host=yourappserver.com
host without http://
Also notice that I put my jacocoant.jar
to ${workspace}/tools/jacoco/jacocoant.jar
Did you start your app server with jacocoagent.jar?
Did you put ant script and jacocoant.jar in your jenkins workspace?
If yes the last step is to configure a jenkins build. Here is the strategy:
jacocoReset
to reset all previously collected data.jacocoReport
to get reportIf everything is right, you will see it-jacoco.exec
in your build workspace.
Look at the screenshot, I also have ant
installed in my workspace in $WORKSPACE/tools/ant
dir, but you can use one that is installed in your jenkins.
Maven sonar:sonar
will do the job (don't forget to configure it), point it to main pom.xml so it will run through all modules. Use sonar.jacoco.itReportPath=$WORKSPACE/it-jacoco.exec
parameter to tell sonar where your integration test report is located. Every time it will analyse new module classes, it will look for information about coverage in it-jacoco.exec
.
By default mvn sonar:sonar
does clean
and deletes your target dir, use sonar.dynamicAnalysis=reuseReports
to avoid it.

Chrome often times tries to do an OPTIONS
call before doing a post. It does this to make sure the CORS headers are in order. It can be problematic if you are not handling the OPTIONS
call in your API controller.
public void Options() { }
You can redirect stdout to /dev/null.
yum install nano > /dev/null
Or you can redirect both stdout and stderr,
yum install nano &> /dev/null
.
But if the program has a quiet option, that's even better.
Maybe you're not doing it as root?
Try sudo nginx -s reload
, if it still doesn't work, you might want to try sudo pkill -HUP nginx
.
Path.GetFullPath(@"c:\windows\temp\..\system32")?
You can select directly into the variable rather than using set:
DECLARE @times int
SELECT @times = COUNT(DidWin)
FROM thetable
WHERE DidWin = 1 AND Playername='Me'
If you need to set multiple variables you can do it from the same select (example a bit contrived):
DECLARE @wins int, @losses int
SELECT @wins = SUM(DidWin), @losses = SUM(DidLose)
FROM thetable
WHERE Playername='Me'
If you are partial to using set, you can use parentheses:
DECLARE @wins int, @losses int
SET (@wins, @losses) = (SELECT SUM(DidWin), SUM(DidLose)
FROM thetable
WHERE Playername='Me');
You can explicitly specify the return type of a lambda by using -> Type
after the arguments list:
[]() -> Type { }
However, if a lambda has one statement and that statement is a return statement (and it returns an expression), the compiler can deduce the return type from the type of that one returned expression. You have multiple statements in your lambda, so it doesn't deduce the type.
Red lines under the ViewBag was my headache for 3 month ). Just remove the Microsoft.CSharp reference from project and then add it again.
Css Part is:
CSS:
@media (max-width: 767px) {
// Align text to center.
.text-xs-center {
text-align: center;
}
}
And the HTML part will be ( this text center work only below 767px width )
HTML:
<div class="col-xs-12 col-sm-6 text-right text-xs-center">
<p>
<a href="#"><i class="fa fa-facebook"></i></a>
<a href="#"><i class="fa fa-twitter"></i></a>
<a href="#"><i class="fa fa-google-plus"></i></a>
</p>
</div>
To get the textbox value, you can use the jQuery val()
function.
For example,
$('input:textbox').val()
– Get textbox value.
$('input:textbox').val("new text message")
– Set the textbox value.
Here are some helper functions I use:
Array.contains = function (arr, key) {
for (var i = arr.length; i--;) {
if (arr[i] === key) return true;
}
return false;
};
Array.add = function (arr, key, value) {
for (var i = arr.length; i--;) {
if (arr[i] === key) return arr[key] = value;
}
this.push(key);
};
Array.remove = function (arr, key) {
for (var i = arr.length; i--;) {
if (arr[i] === key) return arr.splice(i, 1);
}
};

We can count from many ways for the occurrence of substring:-
public class Test1 {
public static void main(String args[]) {
String st = "abcdsfgh yfhf hghj gjgjhbn hgkhmn abc hadslfahsd abcioh abc a ";
count(st, 0, "a".length());
}
public static void count(String trim, int i, int length) {
if (trim.contains("a")) {
trim = trim.substring(trim.indexOf("a") + length);
count(trim, i + 1, length);
} else {
System.out.println(i);
}
}
public static void countMethod2() {
int index = 0, count = 0;
String inputString = "mynameiskhanMYlaptopnameishclMYsirnameisjasaiwalmyfrontnameisvishal".toLowerCase();
String subString = "my".toLowerCase();
while (index != -1) {
index = inputString.indexOf(subString, index);
if (index != -1) {
count++;
index += subString.length();
}
}
System.out.print(count);
}}
Your problem is actually a simple transform acting on the columns:
def f(s):
return s/s.max()
frame.apply(f, axis=0)
Or even more terse:
frame.apply(lambda x: x/x.max(), axis=0)
You should have a look on the -regextype
argument of find
, see manpage:
-regextype type
Changes the regular expression syntax understood by -regex and -iregex
tests which occur later on the command line. Currently-implemented
types are emacs (this is the default), posix-awk, posix-basic,
posix-egrep and posix-extended.
I guess the emacs
type doesn't support the [[:digit:]]
construct. I tried it with posix-extended
and it worked as expected:
find -regextype posix-extended -regex '.*[1234567890]'
find -regextype posix-extended -regex '.*[[:digit:]]'
There are many ways. Here are at least five:

I also faced this problem . You can try any of these steps :
ps -A
)You need to enclose that in <%! %> as follows:
<%!
public String getQuarter(int i){
String quarter;
switch(i){
case 1: quarter = "Winter";
break;
case 2: quarter = "Spring";
break;
case 3: quarter = "Summer I";
break;
case 4: quarter = "Summer II";
break;
case 5: quarter = "Fall";
break;
default: quarter = "ERROR";
}
return quarter;
}
%>
You can then invoke the function within scriptlets or expressions:
<%
out.print(getQuarter(4));
%>
or
<%= getQuarter(17) %>
Keep it simple
var someString = "a_b_c";
var newCharacter = "+";
var newString = someString.substring(0, someString.lastIndexOf('_')) + newCharacter + someString.substring(someString.lastIndexOf('_')+1);
Is the action method on your form pointing to /controller/edit/1
?
Try using one of these:
// the null in the last position is the html attributes, which you usually won't use
// on a form. These invocations are kinda ugly
Html.BeginForm("Edit", "User", new { Id = Model.Id }, FormMethod.Post, null)
Html.BeginForm(new { action="Edit", controller="User", id = Model.Id })
Or inside your form add a hidden "Id" field
@Html.HiddenFor(m => m.Id)
About duli's contribution with my own measurements.
The conclusion is that arrays of integers are faster than vectors of integers (5 times in my example). However, arrays and vectors are arround the same speed for more complex / not aligned data.
Doing row=1
won't change anything, because you'll just overwrite that with the results of the loop.
You want to do next(reader)
to skip one row.

A library that has all the functionality that it seems you're looking for is humanize
. humanize.naturalsize()
seems to do everything you're looking for.
For me, it works when I double checked the parent´s "group ID" and "artifact ID" that in my case were the wrong ones and that was the problem.
One can create an empty array, fill it (otherwise map will skip it) and then map indexes to values:
Array(8).fill().map((_, i) => i * i);
SELECT object_definition (OBJECT_ID(N'dbo.vEmployee'))
My option is to extend ListPreference and it's clean:
public class ListPreferenceShowSummary extends ListPreference {
private final static String TAG = ListPreferenceShowSummary.class.getName();
public ListPreferenceShowSummary(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public ListPreferenceShowSummary(Context context) {
super(context);
init();
}
private void init() {
setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
@Override
public boolean onPreferenceChange(Preference arg0, Object arg1) {
arg0.setSummary(getEntry());
return true;
}
});
}
@Override
public CharSequence getSummary() {
return super.getEntry();
}
}
Then you add in your settings.xml:
<yourpackage.ListPreferenceShowSummary
android:key="key" android:title="title"
android:entries="@array/entries" android:entryValues="@array/values"
android:defaultValue="first value"/>

I was facing same issue. I solved it with retrofit. Let me show this...
If your error JSON structure are like
{
"error": {
"status": "The email field is required."
}
}
My ErrorRespnce.java
public class ErrorResponse {
@SerializedName("error")
@Expose
private ErrorStatus error;
public ErrorStatus getError() {
return error;
}
public void setError(ErrorStatus error) {
this.error = error;
}
}
And this my Error status class
public class ErrorStatus {
@SerializedName("status")
@Expose
private String status;
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
}
Now we need a class which can handle our json.
public class ErrorUtils {
public static ErrorResponse parseError (Response<?> response){
Converter<ResponseBody , ErrorResponse> converter = ApiClient.getClient().responseBodyConverter(ErrorResponse.class , new Annotation[0]);
ErrorResponse errorResponse;
try{
errorResponse = converter.convert(response.errorBody());
}catch (IOException e){
return new ErrorResponse();
}
return errorResponse;
}
}
Now we can check our response in retrofit api call
private void registrationRequest(String name , String email , String password , String c_password){
final Call<RegistrationResponce> registrationResponceCall = apiInterface.getRegistration(name , email , password , c_password);
registrationResponceCall.enqueue(new Callback<RegistrationResponce>() {
@Override
public void onResponse(Call<RegistrationResponce> call, Response<RegistrationResponce> response) {
if (response.code() == 200){
}else if (response.code() == 401){
ErrorResponse errorResponse = ErrorUtils.parseError(response);
Toast.makeText(MainActivity.this, ""+errorResponse.getError().getStatus(), Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFailure(Call<RegistrationResponce> call, Throwable t) {
}
});
}
That's it now you can show your Toast
td.setAttribute('rowspan',x);
Same as WorksheetFunction.EncodeUrl

c = AscW(Mid$(url, i, 1)) And 65535
Select Case c
Case 48 To 57, 65 To 90, 97 To 122, 45, 46, 95 ' Unescaped 0-9A-Za-z-._ '

Mid$(buffer, n) = ChrW(c)
Case Is <= 127 ' Escaped UTF-8 1 bytes U+0000 to U+007F '

Case Is <= 2047 ' Escaped UTF-8 2 bytes U+0080 to U+07FF '
n = n + 6
Mid$(buffer, n - 4) = Hex$(192 + (c \ 64))
Mid$(buffer, n - 1) = Hex$(128 + (c Mod 64))
Case 55296 To 57343 ' Escaped UTF-8 4 bytes U+010000 to U+10FFFF '
i = i + 1
c = 65536 + (c Mod 1024) * 1024 + (AscW(Mid$(url, i, 1)) And 1023)
n = n + 12
Mid$(buffer, n - 10) = Hex$(240 + (c \ 262144))
Mid$(buffer, n - 7) = Hex$(128 + ((c \ 4096) Mod 64))
Mid$(buffer, n - 4) = Hex$(128 + ((c \ 64) Mod 64))
Mid$(buffer, n - 1) = Hex$(128 + (c Mod 64))
Case Else ' Escaped UTF-8 3 bytes U+0800 to U+FFFF '
n = n + 9
Mid$(buffer, n - 7) = Hex$(224 + (c \ 4096))
Mid$(buffer, n - 4) = Hex$(128 + ((c \ 64) Mod 64))
Mid$(buffer, n - 1) = Hex$(128 + (c Mod 64))
End Select
Next
EncodeURL = Left$(buffer, n)
End Function

pgAdmin 4 is a powerful and popular web-based database management tool for PostgreSQL - http://www.pgadmin.org/
The xmlhttp request method is not valid for the files on local disk because the browser security does not allow us to do so.But we can override the browser security by creating a shortcut->right click->properties In target "... browser location path.exe" append --allow-file-access-from-files.This is tested on chrome,however care should be taken that all browser windows should be closed and the code should be run from the browser opened via this shortcut.
For Linux & Unix System you can use ps -ef | grep process_name
to get the full command line.
On SunOS systems, if you want to get full command line, you can use
/usr/ucb/ps -auxww | grep -i process_name
To get the full command line you need to become super user.
pargs -a PROCESS_ID
will give a detailed list of arguments passed to a process. It will output the array of arguments in like this:
argv[o]: first argument
argv[1]: second..
argv[*]: and so on..
I didn't find any similar command for Linux, but I would use the following command to get similar output:
tr '\0' '\n' < /proc/<pid>/environ
The NativeHeap can be increasded by -XX:MaxDirectMemorySize=256M (default is 128)
I've never used it. Maybe you'll find it useful.
The fetchType attribute controls whether the annotated field is fetched immediately when the primary entity is fetched. It does not necessarily dictate how the fetch statement is constructed, the actual sql implementation depends on the provider you are using toplink/hibernate etc.
If you set fetchType=EAGER
This means that the annotated field is populated with its values at the same time as the other fields in the entity. So if you open an entitymanager retrieve your person objects and then close the entitymanager, subsequently doing a person.address will not result in a lazy load exception being thrown.
If you set fetchType=LAZY
the field is only populated when it is accessed. If you have closed the entitymanager by then a lazy load exception will be thrown if you do a person.address. To load the field you need to put the entity back into an entitymangers context with em.merge(), then do the field access and then close the entitymanager.
You might want lazy loading when constructing a customer class with a collection for customer orders. If you retrieved every order for a customer when you wanted to get a customer list this may be a expensive database operation when you only looking for customer name and contact details. Best to leave the db access till later.
For the second part of the question - how to get hibernate to generate optimised SQL?
Hibernate should allow you to provide hints as to how to construct the most efficient query but I suspect there is something wrong with your table construction. Is the relationship established in the tables? Hibernate may have decided that a simple query will be quicker than a join especially if indexes etc are missing.
The other answers suggesting checking out the other branch, then committing to it, only work if the checkout is possible given the local modifications. If not, you're in the most common use case for git stash
:
git stash
git checkout other-branch
git stash pop
The first stash
hides away your changes (basically making a temporary commit), and the subsequent stash pop
re-applies them. This lets Git use its merge capabilities.
If, when you try to pop the stash, you run into merge conflicts... the next steps depend on what those conflicts are. If all the stashed changes indeed belong on that other branch, you're simply going to have to sort through them - it's a consequence of having made your changes on the wrong branch.
On the other hand, if you've really messed up, and your work tree has a mix of changes for the two branches, and the conflicts are just in the ones you want to commit back on the original branch, you can save some work. As usual, there are a lot of ways to do this. Here's one, starting from after you pop and see the conflicts:
# Unstage everything (warning: this leaves files with conflicts in your tree)
git reset
# Add the things you *do* want to commit here
git add -p # or maybe git add -i
git commit
# The stash still exists; pop only throws it away if it applied cleanly
git checkout original-branch
git stash pop
# Add the changes meant for this branch
git add -p
git commit
# And throw away the rest
git reset --hard
Alternatively, if you realize ahead of the time that this is going to happen, simply commit the things that belong on the current branch. You can always come back and amend that commit:
git add -p
git commit
git stash
git checkout other-branch
git stash pop
And of course, remember that this all took a bit of work, and avoid it next time, perhaps by putting your current branch name in your prompt by adding $(__git_ps1)
to your PS1 environment variable in your bashrc file. (See for example the Git in Bash documentation.)

You can do this by installing the task while running as administrator via the TaskSchedler library. I'm making the assumption here that .NET/C# is a suitable platform/language given your related questions.
This library gives you granular access to the Task Scheduler API, so you can adjust settings that you cannot otherwise set via the command line by calling schtasks
, such as the priority of the startup. Being a parental control application, you'll want it to have a startup priority of 0 (maximum), which schtasks
will create by default a priority of 7.
Below is a code example of installing a properly configured startup task to run the desired application as administrator indefinitely at logon. This code will install a task for the very process that it's running from.

Basic implementation using MultipartFormDataContent :-
HttpClient httpClient = new HttpClient();
MultipartFormDataContent form = new MultipartFormDataContent();
form.Add(new StringContent(username), "username");
form.Add(new StringContent(useremail), "email");
form.Add(new StringContent(password), "password");
form.Add(new ByteArrayContent(file_bytes, 0, file_bytes.Length), "profile_pic", "hello1.jpg");
HttpResponseMessage response = await httpClient.PostAsync("PostUrl", form);
response.EnsureSuccessStatusCode();
httpClient.Dispose();
string sd = response.Content.ReadAsStringAsync().Result;
I'm using AS 3.2.1, and was about to try some of the plugins, but was hesitant realizing the plugins are able to monitor any data..
It's actually really simple doing it via the Terminal tab in AS:
adb tcpip 5555
adb connect 192.168.1.101
It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment
to your bean.
@Autowired
private Environment environment;
....
this.environment.getActiveProfiles();
UICollectionView implementation is quite interesting. You can use the simple source code and watch a video tutorial using these links :
https://github.com/Ady901/Demo02CollectionView.git
https://www.youtube.com/watch?v=5SrgvZF67Yw
extension ViewController : UICollectionViewDataSource {
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 2
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return nameArr.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "DummyCollectionCell", for: indexPath) as! DummyCollectionCell
cell.titleLabel.text = nameArr[indexPath.row]
cell.userImageView.backgroundColor = .blue
return cell
}
}
extension ViewController : UICollectionViewDelegate {
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let alert = UIAlertController(title: "Hi", message: "\(nameArr[indexPath.row])", preferredStyle: .alert)
let action = UIAlertAction(title: "OK", style: .default, handler: nil)
alert.addAction(action)
self.present(alert, animated: true, completion: nil)
}
}
String s = "<B><G>Test</G></B><C>Test1</C>";
String pattern ="\\<(.+)\\>([^\\<\\>]+)\\<\\/\\1\\>";
int count = 0;
Pattern p = Pattern.compile(pattern);
Matcher m = p.matcher(s);
while(m.find())
{
System.out.println(m.group(2));
count++;
}
make sure your app is live on developer.facebook.com
This green circle is indicating the app is live
If it is not then follow this two steps for make your app live
Step 1 Go to your application -> setting => and add Contact Email and apply save Changes
Setp 2 Then goto App Review option and make sure this toggle is Yes i added a screen shot
You could always do it recursively like so:
void freeList(struct node* currentNode)
{
if(currentNode->next) freeList(currentNode->next);
free(currentNode);
}
File file = new File(dir, "App.apk");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
startActivity(intent);
I had the same problem and after several attempts, it worked out for me this way. I don't know why, but setting data and type separately screwed up my intent.
Its seems that server is not running properly so ensure that with terminal by
telnet ip port
example
telnet localhost 8069
It will return connected to localhost so it indicates that there is no problem with the connection Else it will return Connection refused it indicates that there is problem with the connection
ifneq ("$(wildcard $(PATH_TO_FILE))","")
FILE_EXISTS = 1
else
FILE_EXISTS = 0
endif
This solution posted above works best. But make sure that you do not stringify the PATH_TO_FILE assignment E.g.,
PATH_TO_FILE = "/usr/local/lib/libhl++.a" # WILL NOT WORK
It must be
PATH_TO_FILE = /usr/local/lib/libhl++.a
Here's a setTimeout equivalent, mostly useful when trying to update the User Interface after a delay.
As you may know, updating the user interface can only by done from the UI thread. AsyncTask does that for you by calling its onPostExecute method from that thread.
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... params) {
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
}
return null;
}
@Override
protected void onPostExecute(Void result) {
// Update the User Interface
}
}.execute();
Try JsonFormat.printer().print(MessageOrBuilder)
, it looks good for proto3. Yet, it is unclear how to convert the actual protobuf
message (which is provided as the java package of my choice defined in the .proto file) to a com.google.protbuf.Message object.
You are looking for dynamic_cast<B*>(pointer)
