I got the same problem after updating my mac on Osx Movaje.
i found this solution :
Try first the bellow command line in your terminal :
brew services restart postgresql
If nothing change :
ps aux | grep postgres
If still nothing change :
ls -ls | grep post
Last command to fix it, removed the postgres lock file by executing from root :
rm /usr/local/var/postgres/postmaster.pid
and then :
brew services restart postgresql

Hope that will help :)
Regards !!
After reading and thrashing around for 2 days, and trying many things found in other notes the following single line was the cure for me on Ubuntu Lucid 10.04 mixed with some Maverick packages and RVM (ruby 1.9.2-p290, rvm 1.10.2 rubygems 1.8.15, rails 3.0.1, postgres 8.4.10) :
gem install pg -- --with-pg-lib=/usr/lib
the result:
Building native extensions. This could take a while...
Successfully installed pg-0.13.1
1 gem installed
Installing ri documentation for pg-0.13.1...
Installing RDoc documentation for pg-0.13.1...
{yea - finally success} !! !note that the output from running pg_config lacks the item -lpq in the LIBS variable on my Ubuntu / Postresql install!!
and why the switch from pq to pg in certain places -- confusing to newbie ??
the thing I still do not understand is the double set of -- and --with(option but I'm way beyond my depth anyway
I had the same problem on Mac OS, but I installed the PostgreSQL gem easily by using the following in a terminal:
ARCHFLAGS="-arch x86_64" gem install pg
(I installed PostgreSQL first with brew install postgresql
.)
You can use varargs
public function yourFunction(Parameter... parameters)
See also
Try to get using:
var count = $("ul > li").size();
alert(count);
You can use a Spring-EL expression, for eg on JDK 1.7:
@Cacheable(value="bookCache", key="T(java.util.Objects).hash(#p0,#p1, #p2)")
And if you want these translation units to share this variable, define int k;
in A.cpp and put extern int k;
in B.cpp.
crcany will generate efficient C code for any CRC, and includes a library of over one hundred known CRC definitions.
Efficient CRC code uses tables instead of bit-wise calculations. crcany generates both byte-wise routines and word-wise routines, the latter tuned to the architecture they are generated on. Word-wise is the fastest. Byte-wise is still much faster than bit-wise, but the implementation is more easily portable over architectures.
You do not seem to have a protocol definition with a specific CRC definition that you need to match. In this case, you can pick any 16-bit CRC in the catalog, and you will get good performance.
If you have a relatively low bit error rate, e.g. single digit number of errors per packet, and you want to maximize your error detection performance, you would need to look at the packet size you are applying the CRC to, assuming that that is constant or bounded, and look at the performance of the best polynomials in Philip Koopman's extensive research. The classic CRCs, such as the CCITT/Kermit 16-bit CRC or the X.25 16-bit CRC are not the best performers.
One of the good 16-bit performers in Koopman's tables that is also in the catalog of CRCs used in practice is CRC-16/DNP. It has very good performance detecting up to 6-bit errors in a packet. Following is the code generated by crcany for that CRC definition. This code assumes a little-endian architecture for the word-wise calculation, e.g. Intel x86 and x86-64, and it assumes that uintmax_t
is 64 bits. crcany can be used to generate alternative code for big-endian and other word sizes.
crc16dnp.h:
// The _bit, _byte, and _word routines return the CRC of the len bytes at mem,
// applied to the previous CRC value, crc. If mem is NULL, then the other
// arguments are ignored, and the initial CRC, i.e. the CRC of zero bytes, is
// returned. Those routines will all return the same result, differing only in
// speed and code complexity. The _rem routine returns the CRC of the remaining
// bits in the last byte, for when the number of bits in the message is not a
// multiple of eight. The low bits bits of the low byte of val are applied to
// crc. bits must be in 0..8.
#include <stddef.h>
// Compute the CRC a bit at a time.

LEFT JOIN

ON [next].rowInt = (SELECT MIN(rowInt) FROM sourceTable WHERE rowInt > [current].rowInt)
EDIT:
Thinking about it, using a subquery in the select (ala Quassnoi's answer) may be more efficient. I would trial different versions, and look at the execution plans to see which would perform best on the size of data set that you have...
EDIT2:
I still see this garnering votes, though it's unlikely many people still use SQL Server 2005.
If you have access to Windowed Functions such as LEAD()
, then use that instead...
SELECT
RowInt,
Value,
LEAD(Value, 1, 0) OVER (ORDER BY RowInt) - Value
FROM

This is my original post, which sparked some debate... because it is wrong:
The switch statement is not the same thing as a big if-else statement. Each case must be unique and evaluated statically. The switch statement does a constant time branch regardless of how many cases you have. The if-else statement evaluates each condition until it finds one that is true.
In fact, the C# switch statement is not always a constant time branch.
In some cases the compiler will use a CIL switch statement which is indeed a constant time branch using a jump table. However, in sparse cases as pointed out by Ivan Hamilton the compiler may generate something else entirely.
This is actually quite easy to verify by writing various C# switch statements, some sparse, some dense, and looking at the resulting CIL with the ildasm.exe tool.
all above answers is correct but however
a = [];
len(list1) - 1 # where 0 - 1 = -1
to be more precisely
a = [];
index = len(a) - 1 if a else None;
if index == None : raise Exception("Empty Array")
since arrays is starting with 0
Excel has a very powerful feature providing for a dropdown select list in a cell, reflecting data from a named region. It'a a very easy configuration, once you have done it before. Two steps are to follow:
Create a named region,
Setup the dropdown in a cell.
There is a detailed explanation of the process HERE.
You may want to clear your DropDown first $('#DropDownQuality').empty();
I had my controller in MVC return a select list with only one item.
$('#DropDownQuality').append(
$('<option></option>').val(data[0].Value).html(data[0].Text));
Note that Visual C++ compilers are removed when you upgrade Visual Studio 2010 Professional or Visual Studio 2010 Express to Visual Studio 2010 SP1 if Windows SDK v7.1 is installed.
For instructions on resolving this, see KB2519277 on the Microsoft Support site.
There's no easy solution. Each way has their pros and cons . But the canonical way is using the first option: multipart/form-data
. As W3 recommendation guide says
The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
We aren't sending forms,really, but the implicit principle still applies. Using base64 as a binary representation, is incorrect because you're using the incorrect tool for accomplish your goal, in other hand, the second option forces your API clients to do more job in order to consume your API service. You should do the hard work in the server side in order to supply an easy-to-consume API. The first option is not easy to debug, but when you do it, it probably never changes.
Using multipart/form-data
you're sticked with the REST/http philosophy. You can view an answer to similar question here.
Another option if mixing the alternatives, you can use multipart/form-data but instead of send every value separate, you can send a value named payload with the json payload inside it. (I tried this approach using ASP.NET WebAPI 2 and works fine).
You can read all of the telephone numbers associated with a contact in the following manner:
Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, personId);
Uri phonesUri = Uri.withAppendedPath(personUri, People.Phones.CONTENT_DIRECTORY);
String[] proj = new String[] {Phones._ID, Phones.TYPE, Phones.NUMBER, Phones.LABEL}
Cursor cursor = contentResolver.query(phonesUri, proj, null, null, null);
Please note that this example (like yours) uses the deprecated contacts API. From eclair onwards this has been replaced with the ContactsContract API.
JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm
page.
One idea is to let the the browser know that it should redirect by adding a redirect
variable to to the resulting object and checking for it in JQuery:
$(document).ready(function(){
jQuery.ajax({
type: "GET",
url: "populateData.htm",
dataType:"json",
data:"userId=SampleUser",
success:function(response){
if (response.redirect) {
window.location.href = response.redirect;
}
else {
// Process the expected results...
}
},
error: function(xhr, textStatus, errorThrown) {
alert('Error! Status = ' + xhr.status);
}
});
});
You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1")
and in JQuery you do on success(!):
//....
success:function(response){
if (response.getResponseHeader('REQUIRES_AUTH') === '1'){
window.location.href = 'login.htm';
}
else {
// Process the expected results...
}
}
//....
Hope that helps.
My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.
The answer by @chepner will copy all the sub-directories irrespective of the fact if it contains the file or not. If you need to exclude the sub-directories that dont contain the file and still retain the directory structure, use
rsync -zarv --prune-empty-dirs --include "*/" --include="*.sh" --exclude="*" "$from" "$to"
Every call to the Iterator.next()
moves the iterator to the next element. If you want to use the current element in more than one statement or expression, you have to store it in a local variable. Or even better, why don't you simply use a for-each loop?
for (String key : map.keySet()) {
System.out.println(key + ":" + map.get(key));
}
Moreover, loop over the entrySet is faster, because you don't query the map twice for each key. Also Map.Entry
implementations usually implement the toString()
method, so you don't have to print the key-value pair manually.
for (Entry<String, Integer> entry : map.entrySet()) {
System.out.println(entry);
}
Suppose you have a List Collection containing many items to show in a ListView, take the following example that iterates through the List Collection:
foreach (Inspection inspection in anInspector.getInspections())
{
ListViewItem item = new ListViewItem();
item.Text=anInspector.getInspectorName().ToString();
item.SubItems.Add(inspection.getInspectionDate().ToShortDateString());
item.SubItems.Add(inspection.getHouse().getAddress().ToString());
item.SubItems.Add(inspection.getHouse().getValue().ToString("C"));
listView1.Items.Add(item);
}
That code produces the following output in the ListView (of course depending how many items you have in the List Collection):
Basically the first column is a listviewitem containing many subitems (other columns). It may seem strange but listview is very flexible, you could even build a windows-like file explorer with it!
You can use date filter to convert in date and display in specific format.
In .ts file (typescript):
let dateString = '1968-11-16T00:00:00'
let newDate = new Date(dateString);
In HTML:
{{dateString | date:'MM/dd/yyyy'}}
Below are some formats which you can implement :
Backend:
public todayDate = new Date();
HTML :
<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>
<option value="MM/dd/yyyy h:mm:ss a">[{{todayDate | date:'MM/dd/yyyy h:mm:ss a'}}]</option>
<option value="MMMM d">[{{todayDate | date:'MMMM d'}}]</option>
<option value="yyyy-MM-ddTHH:mm:ss">[{{todayDate | date:'yyyy-MM-ddTHH:mm:ss'}}]</option>
<option value="h:mm a">[{{todayDate | date:'h:mm a'}}]</option>
<option value="h:mm:ss a">[{{todayDate | date:'h:mm:ss a'}}]</option>
<option value="EEEE, MMMM d, yyyy hh:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy hh:mm:ss a'}}]</option>
<option value="MMMM yyyy">[{{todayDate | date:'MMMM yyyy'}}]</option>
</select>
Local storage: It keeps store the user information data without expiration date this data will not be deleted when user closed the browser windows it will be available for day, week, month and year.
//Set the value in a local storage object
localStorage.setItem('name', myName);
//Get the value from storage object
localStorage.getItem('name');
//Delete the value from local storage object
localStorage.removeItem(name);//Delete specifice obeject from local storege
localStorage.clear();//Delete all from local storege
Session Storage: It is same like local storage date except it will delete all windows when browser windows closed by a web user.
//set the value to a object in session storege
sessionStorage.myNameInSession = "Krishna";

Ran into this same issue while using the CURL command inside my Dockerfile. As Gilles pointed out, we have to install curl first. These are the commands to be added in the 'Dockerfile'.
FROM ubuntu:16.04
# Install prerequisites
RUN apt-get update && apt-get install -y \
curl
CMD /bin/bash
Three related packages for covering this issue with many advanced options are:
If you want to do it by ClassName you could do:
<script type="text/javascript">
function hideTd(className){
var elements;
if (document.getElementsByClassName)
{
elements = document.getElementsByClassName(className);
}
else
{
var elArray = [];
var tmp = document.getElementsByTagName(elements);
var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)");
for ( var i = 0; i < tmp.length; i++ ) {
if ( regex.test(tmp[i].className) ) {
elArray.push(tmp[i]);
}
}
elements = elArray;
}
for(var i = 0, i < elements.length; i++) {
if( elements[i].textContent == ''){
elements[i].style.display = 'none';
}
}
}
</script>
adb shell
am start -n com.package.name/com.package.name.ActivityName
Or you can use this directly:
adb shell am start -n com.package.name/com.package.name.ActivityName
You can also specify actions to be filter by your intent-filters:
am start -a com.example.ACTION_NAME -n com.package.name/com.package.name.ActivityName
As of 2020, you should use the Clipboard Api.
navigator.clipboard.writeText('text here you want to copy').then(function () {
alert('It worked! Do a CTRL - V to paste')
}, function () {
alert('Failure to copy. Check permissions for clipboard')
});
Here is more info about interacting with the clipboard
First convert you datagridview's data to List, then convert List to DataTable
public static DataTable ToDataTable<T>( this List<T> list) where T : class {
Type type = typeof(T);
var ps = type.GetProperties ( );
var cols = from p in ps
select new DataColumn ( p.Name , p.PropertyType );
DataTable dt = new DataTable();
dt.Columns.AddRange(cols.ToArray());
list.ForEach ( (l) => {
List<object> objs = new List<object>();
objs.AddRange ( ps.Select ( p => p.GetValue ( l , null ) ) );
dt.Rows.Add ( objs.ToArray ( ) );
} );
return dt;
}
If you need to use trim in select query, you can also use regular expressions
SELECT * FROM table_name WHERE field RLIKE ' * query-string *'
return rows with field like ' query-string '
This works well for specific articles where the text is all wrapped in <p>
tags. Since the web is an ugly place, it's not always the case.
Often, websites will have text scattered all over, wrapped in different types of tags (e.g. maybe in a <span>
or a <div>
, or an <li>
).
To find all text nodes in the DOM, you can use soup.find_all(text=True)
.
This is going to return some undesired text, like the contents of <script>
and <style>
tags. You'll need to filter out the text contents of elements you don't want.
blacklist = [
'style',
'script',
# other elements,
]
text_elements = [t for t in soup.find_all(text=True) if t.parent.name not in blacklist]
If you are working with a known set of tags, you can tag the opposite approach:
whitelist = [
'p'
]
text_elements = [t for t in soup.find_all(text=True) if t.parent.name in whitelist]
I would use python-dpkt. Here is the documentation: http://www.commercialventvac.com/dpkt.html

for ts, pkt in dpkt.pcap.Reader(open(filename,'r')):

if eth.type!=dpkt.ethernet.ETH_TYPE_IP:
continue
ip=eth.data
ipcounter+=1
if ip.p==dpkt.ip.IP_PROTO_TCP:
tcpcounter+=1
if ip.p==dpkt.ip.IP_PROTO_UDP:
udpcounter+=1
print "Total number of packets in the pcap file: ", counter
print "Total number of ip packets: ", ipcounter
print "Total number of tcp packets: ", tcpcounter
print "Total number of udp packets: ", udpcounter
Update:
"I hoped (and still hope) that there is something like my beloved SQL*Plus for Oracle that can execute a file with all kinds of SQL Statements."
If you're looking for a simple program that can import a file and execute the SQL statements in it, take a look at DBWConsole (freeware). I have used it to process DDL scripts (table schema) as well as action queries. It does not return data sets so it's not useful for SELECT queries. It supports single line comments prefixed by -- but not multi-line comments wrapped in /* */. It supports command line parameters.
If you want an interactive UI like Oracle SQL Developer or SSMS for Access then Matthew Lock's reference to WinSQL is what you should try.
You would use data validation for this. Click in the cell you want to have a multiple drop down > DATA > Validation > Criteria (List from a Range) - here you select form a list of items you want in the drop down. And .. you are good. I have included an example to reference.
Got similar problem after enabled flavors (dev, stage).
Before flavors my path resource looked like this:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="my_images"
path="Android/data/pl.myapp/files/Pictures" />
</paths>
After added android:authorities="${applicationId}.fileprovider" in Manifest appId was pl.myapp.dev or pl.myapp.stage depends on flavor and app started crashing. I removed full path and replaced it with dot and everything started working.
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="my_images"
path="." />
</paths>
I had to use
powershell.AddCommand("Get-ADPermission");
powershell.AddParameter("Identity", "complete id path with OU in it");
to get past this error
If you want to do a horizontal centering, just put the form inside a DIV tag and apply align="center" attribute to it. So even if the form width is changed, your centering will remain the same.
<div align="center"><form id="form_login"><!--form content here--></form></div>
UPDATE
@G-Cyr is right. align="center"
attribute is now obsolete. You can use text-align
attribute for this as following.
<div style="text-align:center"><form id="form_login"><!--form content here--></form></div>
This will center all the content inside the parent DIV. An optional way is to use margin: auto
CSS attribute with predefined widths and heights. Please follow the following thread for more information.
How to horizontally center a in another ?
Vertical centering is little difficult than that. To do that, you can do the following stuff.
html
<body>
<div id="parent">
<form id="form_login">
<!--form content here-->
</form>
</div>
</body>
Css
#parent {
display: table;
width: 100%;
}
#form_login {
display: table-cell;
text-align: center;
vertical-align: middle;
}
Please don't use techniques described in other answers here. They are either not working with css3 animations size changes, floating layout changes or changes that don't come from jQuery land. You can use a resize-detector, a event-based approach, that doesn't waste your CPU time.
https://github.com/marcj/css-element-queries
It contains a ResizeSensor class you can use for that purpose.
new ResizeSensor(jQuery('#mainContent'), function(){
console.log('main content dimension changed');
});

The isConnected
method won't help, it will return true
even if the remote side has closed the socket. Try this:
public class MyServer {
public static final int PORT = 12345;
public static void main(String[] args) throws IOException, InterruptedException {
ServerSocket ss = ServerSocketFactory.getDefault().createServerSocket(PORT);
Socket s = ss.accept();
Thread.sleep(5000);
ss.close();
s.close();
}
}
public class MyClient {
public static void main(String[] args) throws IOException, InterruptedException {
Socket s = SocketFactory.getDefault().createSocket("localhost", MyServer.PORT);
System.out.println(" connected: " + s.isConnected());
Thread.sleep(10000);
System.out.println(" connected: " + s.isConnected());
}
}
Start the server, start the client. You'll see that it prints "connected: true" twice, even though the socket is closed the second time.
The only way to really find out is by reading (you'll get -1 as return value) or writing (an IOException
(broken pipe) will be thrown) on the associated Input/OutputStreams.
just simply (PowerShell V5)
Get-ChildItem "C:\temp" -Recurse -File | Where CreationTime -lt (Get-Date).AddDays(-15) | Remove-Item -Force
I don't know ASP.NET very well, but can you use the ternary operator?

Something like: (x=Eval("item")) == Null ? 0 : x
In my case I have pushed changes to origin/master
and then realised I should not have done so :-( This was complicated by the fact that the local changes were in a subtree. So I went back to the last good commit before the "bad" local changes (using SourceTree) and then I got the "divergence message".
After fixing my mess locally (the details are not important here) I wanted to "move back in time" the remote origin/master
branch so that it would be in sync with the local master
again. The solution in my case was:
git push origin master -f
Note the -f
(force) switch. This deleted the "bad changes" that had been pushed to origin/master
by mistake and now the local and remote branches are in sync.
Please keep in mind that this is a potentially destructive operation so perform it only if you are 100% sure that "moving back" the remote master in time is OK.
To write:
using (System.IO.StreamWriter file =
new System.IO.StreamWriter(System.IO.File.Create(filePath).Dispose()))
{
file.WriteLine("your text here");
}
If for any reason, you want to avoid using sed, the following will print the line matching TERMINATE
till the end of the file:
tail -n "+$(grep -n 'TERMINATE' file | head -n 1 | cut -d ":" -f 1)" file
and the following will print from the following line matching TERMINATE
till the end of the file:
tail -n "+$(($(grep -n 'TERMINATE' file | head -n 1 | cut -d ":" -f 1)+1))" file
It takes 2 processes to do what sed can do in one process, and if the file changes between the execution of grep and tail, the result can be incoherent, so I recommend using sed. Moreover, if the file dones not contain TERMINATE
, the 1st command fails.
This can be done by using unlist
before as.vector
.
The result is the same as using the parameter use.names=FALSE
.
as.vector(unlist(myList))
read
won't read from a pipe (or possibly the result is lost because the pipe creates a subshell). You can, however, use a here string in Bash:
$ read a b c <<< $(echo 1 2 3)
$ echo $a $b $c
1 2 3
But see @chepner's answer for information about lastpipe

Make the multiple axes first and pass them to the Pandas plot function, like:
fig, axs = plt.subplots(1,2)
df['korisnika'].plot(ax=axs[0])
df['osiguranika'].plot(ax=axs[1])
It still gives you 1 figure, but with two different plots next to each other.
No, nothing built-in. Do it yourself:
Scripting.Dictionary
objectFor
loop over your array (be sure to use LBound()
and UBound()
instead of looping from 0 to x!)Exists()
on the dictionary. Add every array value (that doesn't already exist) as a key to the dictionary (CStr()
since keys must be stringsScripting.Dictionary
), also store the array value itself into the dictionary.Keys()
(or Items()
) to return all values of the dictionary as a new, now unique array.For others who are looking to remove a built-in library, the route is to get into PackageContents -> Java -> libraries.
BUT : IT MAKES NO SENSE TO ELIMINATE LIBRARIES inside the app, they don't take space, don't have any influence on performance, and if you don't know what you are doing, you can harm the program. I did it because Arduino told me about libraries to update, showing then a board I don't have, and when saying ok it wanted to install a lot of new dependencies - I just felt forced to something I don't want, so I deinstalled that board.
It is possible. But you have to hack it a little, there is a code What you have to do is to run stand alone server and "patch" RemoteWebDriver

If you want a css only solution you can use active
.crossRotate:active {
transform: rotate(45deg);
-webkit-transform: rotate(45deg);
-ms-transform: rotate(45deg);
}
But the transformation will not persist when the activity moves. For that you need javascript (jquery click and css is the cleanest IMO).
$( ".crossRotate" ).click(function() {
if ( $( this ).css( "transform" ) == 'none' ){
$(this).css("transform","rotate(45deg)");
} else {
$(this).css("transform","" );
}
});
box-sizing: border-box;
width: 100%;
padding: 5px;
box-sizing: border box; makes it so that padding, margin and border are included in the width calculations.
string = 'http://www.domain.com/?s=some&two=20'
cut_string = string.split('&')
new_string = cut_string[0]
print(new_string)
Reasoning from the comments to this question, it appears a lack of an adjusted session.save_path causes this misbehavior of PHP’s session handler. Just specify a directory (outside your document root directory) that exists and is both readable and writeable by PHP to fix this.
An svg dynamic solution for any screen is the following:
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" stroke-width="1" stroke="#000">
<line x1="0" y1="0" x2="100%" y2="100%"/>
<line x1="100%" y1="0" x2="0" y2="100%"/>
</svg>
And if you want to keep it in background use the position: absolute
with top and left 0.
This will solve my “SMTP Error: Could not authenticate” in PHPMailer error.
What to do to correct this is create a file called php.ini and save it in the same location as your .htaccess file and enter the following code instead:
upload_max_filesize = "250M"
post_max_size = "250M"
If all of these rows are related and you need to alter the tabular data ... why not just wrap the entire table in a form, and change GET to POST (unless you know that you're not going to be sending more than the max amount of data a GET request can send).
I cannot wrap the entire table in a form, because some input fields of each row are input type="file" and files may be large. When the user submits the form, I want to POST only fields of current row, not all fields of the all rows which may have unneeded huge files, causing form to submit very slowly.
So, I tried incorrect nesting: tr/form and form/tr. However, it works only when one does not try to add new inputs dynamically into the form. Dynamically added inputs will not belong to incorrectly nested form, thus won't get submitted. (valid form/table dynamically inputs are submitted just fine).
Nesting div[display:table]/form/div[display:table-row]/div[display:table-cell] produced non-uniform widths of grid columns. I managed to get uniform layout when I replaced div[display:table-row] to form[display:table-row] :
div.grid {
display: table;
}
div.grid > form {
display: table-row;
div.grid > form > div {
display: table-cell;
}
div.grid > form > div.head {
text-align: center;
font-weight: 800;
}
For the layout to be displayed correctly in IE8:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
...
<meta http-equiv="X-UA-Compatible" content="IE=8, IE=9, IE=10" />
Sample of output:
<div class="grid" id="htmlrow_grid_item">
<form>
<div class="head">Title</div>
<div class="head">Price</div>
<div class="head">Description</div>
<div class="head">Images</div>
<div class="head">Stock left</div>
<div class="head">Action</div>
</form>
<form action="/index.php" enctype="multipart/form-data" method="post">
<div title="Title"><input required="required" class="input_varchar" name="add_title" type="text" value="" /></div>
It would be much harder to make this code work in IE6/7, however.
You may use Window#dispose() method to release all of the native screen resources, subcomponents, and all of its owned children.
The System.exit(0)

For unix, combining just git
and the built-in diff
:
git show HEAD:path/to/file | diff -y - path/to/file
Of course, you can replace HEAD with any other git reference, and you probably want to add something like -W 170
to the diff command.
This assumes that you are just comparing your directory contents with a past commit. Comparing between two commits is more complex. If your shell is bash
you can use "process substitution":
diff -y -W 170 <(git show REF1:path/to/file) <(git show REF2:path/to/file)
where REF1
and REF2
are git references – tags, branches or hashes.
Try Find out divs height and setting div height (Similar to the one Matt posted but using a loop)
In Java 11+ it's possible with variables too. The only condition is it must be a constant.
For Example:
final String LEFT = "left";
final String RIGHT = "right";
final String UP = "up";
final String DOWN = "down";
String var = ...;
switch (var) {
case LEFT:
case RIGHT:
case DOWN:
default:
return 0;
}
PS. I've not tried this with earlier jdks. So please update the answer if it's supported there too.
In MS Windows the temporary directory is set by the environment variable TEMP
. In XP, the temporary directory was set per-user as Local Settings\Temp.
If you change your TEMP environment variable to C:\temp
, then you get the same when you run :
System.out.println(System.getProperty("java.io.tmpdir"));

This exception is encountered when you are expecting a response, but the socket has been abruptly closed.
Java's HTTPClient
, found here, throws a SocketException
with message "Unexpected end of file from server" in a very specific circumstance.
After making a request, HTTPClient
gets an InputStream
tied to the socket associated with the request. It then polls that InputStream
repeatedly until it either:
InputStream
is reached before 8 characters are readIn case of number 2, HTTPClient
will throw this SocketException
if any of the following are true:
This indicates that the TCP socket has been closed before the server was able to send a response. This could happen for any number of reasons, but some possibilities are:
Note: When Nginx reloads its config, it forcefully closes any in-flight HTTP Keep-Alive connections (even POSTs), causing this exact error.
It seems to work if you use
div#scrollable {
overflow-y: scroll;
height: 100%;
}
and add padding-bottom: 60px
to div.sidebar
.
For example: http://jsfiddle.net/AKL35/6/
However, I am unsure why it must be 60px
.
Also, you missed the f
from overflow-y: scroll;
You need to set the parent element to 100%
as well
html, body {
height: 100%;
}
Demo (Changed the background
for demo purpose)
Also, when you want to cover entire screen, seems like you want to dim
, so in this case, you need to use position: fixed;
#dimScreen {
width: 100%;
height: 100%;
background:rgba(255,255,255,0.5);
position: fixed;
top: 0;
left: 0;
z-index: 100; /* Just to keep it at the very top */
}
If that's the case, than you don't need html, body {height: 100%;}
For those using the Symfony framework, the phpseclib can also be used to connect via SSH. It can be installed using composer:
composer require phpseclib/phpseclib
Next, simply use it as follows:
use phpseclib\Net\SSH2;
// Within a controller for example:
$ssh = new SSH2('hostname or ip');
if (!$ssh->login('username', 'password')) {
// Login failed, do something
}
$return_value = $ssh->exec('command');
Another potential cause, for other people coming across the same error message is that this error will occur if you are accessing a table in a different schema from the one you have authenticated with.
In this case you would need to add the schema name to your entity entry:
@Table(name= "catalog", schema = "targetSchemaName")
If for some reason it's still not working. First option for Laravel The second option for any application
FIRST OPTION:
As in the example above, we create middleware
php artisan make:middleware Cors
Add the following code to app/Http/Middleware/Cors.php
:
public function handle($request, Closure $next)
{
return $next($request)
->header('Access-Control-Allow-Origin', '*')
->header('Access-Control-Allow-Methods', 'GET, POST, PUT, PATCH, DELETE, OPTIONS')
->header('Access-Control-Allow-Headers', 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range');
}
Look closely, the amount of data in the header ->header('Access-Control-Allow-Headers',
Step three, add middleware to $routeMiddleware
array in app/Http/Kernel.php
protected $routeMiddleware = [
....
'cors' => \App\Http\Middleware\Cors::class,
];
SECOND OPTION:
Open the nginx.conf settings for your domain.
sudo nano /etc/nginx/sites-enabled/your-domain.conf
Inside the server settings server { listen 80; .... }
please add the following code:
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Headers' 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE,PATCH';
Because &
has a lesser priority than ==
.
Your code is equivalent to a[0] & (1 == 0)
, and unless a[0]
is a boolean this won't compile...
You need to:
(a[0] & 1) == 0
etc etc.
(yes, Java does hava a boolean &
operator -- a non shortcut logical and)
Let's see the code of how we can use this
import react from 'react'
function Header()
{
return <p><b><h1>This is the Heading section</h1></b></p>;
}
**export default Header;**
<?php
$taxonomy = 'product_cat';
$orderby = 'name';
$show_count = 0; // 1 for yes, 0 for no
$pad_counts = 0; // 1 for yes, 0 for no
$hierarchical = 1; // 1 for yes, 0 for no
$title = '';
$empty = 0;
$args = array(
'taxonomy' => $taxonomy,
'orderby' => $orderby,
'show_count' => $show_count,
'pad_counts' => $pad_counts,
'hierarchical' => $hierarchical,
'title_li' => $title,
'hide_empty' => $empty
);
$all_categories = get_categories( $args );
foreach ($all_categories as $cat) {
if($cat->category_parent == 0) {
$category_id = $cat->term_id;
echo '<br /><a href="'. get_term_link($cat->slug, 'product_cat') .'">'. $cat->name .'</a>';
$args2 = array(
'taxonomy' => $taxonomy,
'child_of' => 0,
'parent' => $category_id,
'orderby' => $orderby,
'show_count' => $show_count,
'pad_counts' => $pad_counts,
'hierarchical' => $hierarchical,
'title_li' => $title,
'hide_empty' => $empty
);
$sub_cats = get_categories( $args2 );
if($sub_cats) {
foreach($sub_cats as $sub_category) {
echo $sub_category->name ;
}
}
}
}
?>
This will list all the top level categories and subcategories under them hierarchically. do not use the inner query if you just want to display the top level categories. Style it as you like.
You can use mkdir
:
mkdir -p ~/bar/baz/ && \
mv foo.c ~/bar/baz/
A simple script to do it automatically (untested):
#!/bin/sh
# Grab the last argument (argument number $#)
eval LAST_ARG=\$$#
# Strip the filename (if it exists) from the destination, getting the directory
DIR_NAME=`echo $2 | sed -e 's_/[^/]*$__'`
# Move to the directory, making the directory if necessary
mkdir -p "$DIR_NAME" || exit
mv "$@"
There isn't any big deal in your above snippet, but imagine a function with a few more arguments and quite a few more lines of code. Then you decide to rename your data
argument as yadda
, but miss one of the places it is used in the function's body... Now data
refers to the global, and you start having weird behaviour - where you would have a much more obvious NameError
if you didn't have a global name data
.
Also remember that in Python everything is an object (including modules, classes and functions), so there's no distinct namespaces for functions, modules or classes. Another scenario is that you import function foo
at the top of your module, and use it somewhere in your function body. Then you add a new argument to your function and named it - bad luck - foo
.
Finally, built-in functions and types also live in the same namespace and can be shadowed the same way.
None of this is much of a problem if you have short functions, good naming and a decent unit test coverage, but well, sometimes you have to maintain less than perfect code and being warned about such possible issues might help.
By default the underlying type of each element in the enum is integer.
enum Values
{
A,
B,
C
}
You can also specify custom value for each item:
enum Values
{
A = 10,
B = 11,
C = 12
}
int x = (int)Values.A; // x will be 10;
Note: By default, the first enumerator has the value 0.
document.getElementById("id").innerHTML='<object type="text/html" data="x.html"></object>';
I've found with 1.5 components that abstracting the styling from the DOM to work best in my async situation.
Example:
<div ng-style="{ 'background': $ctrl.backgroundUrl }"></div>
And in the controller, something likes this:
this.$onChanges = onChanges;
function onChanges(changes) {
if (changes.value.currentValue){
$ctrl.backgroundUrl = setBackgroundUrl(changes.value.currentValue);
}
}
function setBackgroundUrl(value){
return 'url(' + value.imgUrl + ')';
}
You simply misspelled $stateParam
, it should be $stateParams
(with an s). That's why you get undefined ;)
It's simply the domain that your "facebook" application (wich means application visible on facebook but hosted on the website www.xyz.com) will be hosted. So you can put App Domain = www.xyz.com
All solutions work great, except when applied in programming languages that closures (e.g. Coda, Excel, Spreadsheet's REGEXREPLACE
).
Two original solutions of mine below use only 1 concatenation and 1 regex.
The idea is to append replacement values if they are not already in the string. Then, using a single regex, we perform all needed replacements:
var str = "I have a cat, a dog, and a goat.";
str = (str+"||||cat,dog,goat").replace(
/cat(?=[\s\S]*(dog))|dog(?=[\s\S]*(goat))|goat(?=[\s\S]*(cat))|\|\|\|\|.*$/gi, "$1$2$3");
document.body.innerHTML = str;
_x000D_
Explanations:
cat(?=[\s\S]*(dog))
means that we look for "cat". If it matches, then a forward lookup will capture "dog" as group 1, and "" otherwise."$1$2$3"
(the concatenation of all three groups), which will always be either "dog", "cat" or "goat" for one of the above casesstr+"||||cat,dog,goat"
, we remove them by also matching \|\|\|\|.*$
, in which case the replacement "$1$2$3"
will evaluate to "", the empty string.One problem with Method #1 is that it cannot exceed 9 replacements at a time, which is the maximum number of back-propagation groups. Method #2 states not to append just replacement values, but replacements directly:
var str = "I have a cat, a dog, and a goat.";
str = (str+"||||,cat=>dog,dog=>goat,goat=>cat").replace(
/(\b\w+\b)(?=[\s\S]*,\1=>([^,]*))|\|\|\|\|.*$/gi, "$2");
document.body.innerHTML = str;
_x000D_
Explanations:
(str+"||||,cat=>dog,dog=>goat,goat=>cat")
is how we append a replacement map to the end of the string.(\b\w+\b)
states to "capture any word", that could be replaced by "(cat|dog|goat) or anything else.(?=[\s\S]*...)
is a forward lookup that will typically go to the end of the document until after the replacement map.
,\1=>
means "you should find the matched word between a comma and a right arrow"([^,]*)
means "match anything after this arrow until the next comma or the end of the doc"|\|\|\|\|.*$
is how we remove the replacement map.mkdir [-switch] foldername
-p
is a switch which is optional, it will create subfolder and parent folder as well even parent folder doesn't exist.
From the man page:
-p, --parents no error if existing, make parent directories as needed
Example:
mkdir -p storage/framework/{sessions,views,cache}
This will create subfolder sessions,views,cache inside framework folder irrespective of 'framework' was available earlier or not.
If your example represents your real code, the problem is not in the push
, it's that your constructor doesn't do anything.
You need to declare and initialize the x
and y
members.
Explicitly:
export class Pixel {
public x: number;
public y: number;
constructor(x: number, y: number) {
this.x = x;
this.y = y;
}
}
Or implicitly:
export class Pixel {
constructor(public x: number, public y: number) {}
}
Yet another solution, assuming the number of items in the folder is not huge:
tar -czf workspace.tar.gz `ls -A`
(ls -A
prints normal and hidden files but not "." and ".." as ls -a
does.)
Hold ctrl key and then click on class of which you want to see the inner working (for ex: String
) then you will find there button "Attach Source". Click on it. Then click on External Folder. Then browse to your jdk location, per instance C:\Program Files\Java\jdk1.6.0
. That's it.
Perhaps the simplest option is just to put those functions outside of the class:
class Dog(object):
def __init__(self, name):
self.name = name
def bark(self):
if self.name == "Doggy":
return barking_sound()
else:
return "yip yip"
def barking_sound():
return "woof woof"
Using this method, functions which modify or use internal object state (have side effects) can be kept in the class, and the reusable utility functions can be moved outside.
Let's say this file is called dogs.py
. To use these, you'd call dogs.barking_sound()
instead of dogs.Dog.barking_sound
.
If you really need a static method to be part of the class, you can use the staticmethod decorator.
TypeScript isn't giving you a gun to shoot yourself in the foot with.
The iterator variable is a string because it is a string, full stop. Observe:
var obj = {};
obj['0'] = 'quote zero quote';
obj[0.0] = 'zero point zero';
obj['[object Object]'] = 'literal string "[object Object]"';
obj[<any>obj] = 'this obj'
obj[<any>undefined] = 'undefined';
obj[<any>"undefined"] = 'the literal string "undefined"';
for(var key in obj) {
console.log('Type: ' + typeof key);
console.log(key + ' => ' + obj[key]);
}
How many key/value pairs are in obj
now? 6, more or less? No, 3, and all of the keys are strings:
Type: string
0 => zero point zero
Type: string
[object Object] => this obj;
Type: string
undefined => the literal string "undefined"
I would add that since version 3.6, we can use fstrings like the following
foo = "john"
bar = "smith"
print(f"My name is {foo} {bar}")
Which give
My name is john smith
Everything is converted to strings
mylist = ["foo", "bar"]
print(f"mylist = {mylist}")
Result:
mylist = ['foo', 'bar']
you can pass function, like in others formats method
print(f'Hello, here is the date : {time.strftime("%d/%m/%Y")}')
Giving for example
Hello, here is the date : 16/04/2018
My guess the compiler is complaining about an invalid annotation. I've noticed that Eclipse doesnt show all errors, like a comma at the end of an array in a annotation. But the standard javac
does.
The variable set by varStatus
is a LoopTagStatus
object, not an int. Use:
<div id="divIDNo${theCount.index}">
To clarify:
${theCount.index}
starts counting at 0
unless you've set the begin
attribute${theCount.count}
starts counting at 1

You only want to use Invoke
or BeginInvoke
for the bare minimum piece of work required to change the UI. Your "heavy" method should execute on another thread (e.g. via BackgroundWorker
) but then using Control.Invoke
/Control.BeginInvoke
just to update the UI. That way your UI thread will be free to handle UI events etc.
See my threading article for a WinForms example - although the article was written before BackgroundWorker
arrived on the scene, and I'm afraid I haven't updated it in that respect. BackgroundWorker
merely simplifies the callback a bit.
You could try
document.getElementsByTagName('body')[0].appendChild(i);
Now that won't do you any good if the code is running in the <head>
, and running before the <body>
has even been seen by the browser. If you don't want to mess with "onload" handlers, try moving your <script>
block to the very end of the document instead of the <head>
.
Not a direct answer, but may help some people ending up here.
If you are using GatsbyJS there is a plugin that automatically adds target="_blank"
to external links in your markdown.
It's called gatsby-remark-external-links and the usage is like so:
yarn add gatsby-remark-external-links
plugins: [
{
resolve: `gatsby-transformer-remark`,
options: {
plugins: [{
resolve: "gatsby-remark-external-links",
options: {
target: "_blank",
rel: "noopener noreferrer"
}
}]
}
},
It also takes care of the rel="noopener noreferrer"
.
Reference the docs if you need more options.
To add to the other answers in Android, Ems size, can, by default, vary in each language and input.
It means that if you want to set a minimum width to a text field, defined by number of chars, you have to calculate the Ems properly and set it, according to your typeface and font size with the Ems attribute.
To those of you struggle with this, you can calculate the hint size yourself to avoid messing with Ems:
val tf = TextField()
val layout = TextInputLayout()

val measureText = tf.paint.measureText(hint).toInt()
tf.width = tf.paddingLeft + tf.paddingRight + measureText.toInt()
layout.hint = hint
Here is a simple .split
solution that works without regex.
This is an answer for Python split() without removing the delimiter, so not exactly what the original post asks but the other question was closed as a duplicate for this one.
def splitkeep(s, delimiter):
split = s.split(delimiter)
return [substr + delimiter for substr in split[:-1]] + [split[-1]]
Random tests:
import random
CHARS = [".", "a", "b", "c"]
assert splitkeep("", "X") == [""] # 0 length test
for delimiter in ('.', '..'):
for _ in range(100000):
length = random.randint(1, 50)
s = "".join(random.choice(CHARS) for _ in range(length))
assert "".join(splitkeep(s, delimiter)) == s
getText is a member of the your Activity so it must be called when "this" exists. Your static variable is initialized when your class is loaded before your Activity is created.
Since you want the variable to be initialized from a Resource string then it cannot be static. If you want it to be static you can initialize it with the String value.
you should try using os.walk
yourpath = 'path'
import os
for root, dirs, files in os.walk(yourpath, topdown=False):
for name in files:
print(os.path.join(root, name))
stuff
for name in dirs:
print(os.path.join(root, name))
stuff
@kajetons' answer is fully functional.
You can also pass multiple variables by passing them like: use($var1, $var2)
DB::table('users')->where(function ($query) use ($activated,$var2) {
$query->where('activated', '=', $activated);
$query->where('var2', '>', $var2);
})->get();
I would suggest using it as an extension of String:
extension String {
public var isEmail: Bool {
let dataDetector = try? NSDataDetector(types: NSTextCheckingResult.CheckingType.link.rawValue)
let firstMatch = dataDetector?.firstMatch(in: self, options: NSRegularExpression.MatchingOptions.reportCompletion, range: NSRange(location: 0, length: length))
return (firstMatch?.range.location != NSNotFound && firstMatch?.url?.scheme == "mailto")
}
public var length: Int {
return self.characters.count
}
}
And to use it:
if "[email protected]".isEmail { // true
print("Hold the Door")
}
Javascript 1.7 added destructured assignment which allows you to do essentially what you are after.
function getTuple(){
return ["Bob", 24];
}
var [a, b] = getTuple();
// a === "bob" , b === 24 are both true
See in_array
<?php
$arr = array(0 => "kitchen", 1 => "bedroom", 2 => "living_room", 3 => "dining_room");
if (in_array("kitchen", $arr))
{
echo sprintf("'kitchen' is in '%s'", implode(', ', $arr));
}
?>
Jasmine doesn't have that functionality, but you might be able to hack something together using Object.defineProperty
.
You could refactor your code to use a getter function, then spy on the getter.
spyOn(myObj, 'getValueA').andReturn(1);
expect(myObj.getValueA()).toBe(1);
For just elements this can be used to find the index of an element amongst it's sibling elements:
function getElIndex(el) {
for (var i = 0; el = el.previousElementSibling; i++);
return i;
}
Note that previousElementSibling
isn't supported in IE<9.
Hope this helps. From eclipse, you right click the project -> Run As -> Run on Server and then it worked for me. I used Eclipse Jee Neon and Apache Tomcat 9.0. :)
I just removed the head portion in index.html file and it worked fine.This is the head tag in html file
You can do it in your javascript (controller) or in your html (angular view)...
js:
$scope.arr = [];
for ( p in data ) {
$scope.arr.push(p);
}
html:
<tr ng-repeat="(k, v) in data">
<td>{{k}}<input type="text" ng-model="data[k]"></td>
</tr>
I believe the html way is more angular , but you can also do in your controller and retrieve it in your html...
also not a bad idea to look at the Object keys, they give you the an array of the keys if you need them, more info here:
https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Object/keys
What I'll do which is very simple but waste memory is to map the values with a key and do the oposite to map the keys with a value making this:
private Map<Object, Object> team1 = new HashMap<Object, Object>();
it's important that you use <Object, Object>
so you can map keys:Value
and Value:Keys
like this
team1.put("United", 5);
team1.put(5, "United");
So if you use team1.get("United") = 5
and team1.get(5) = "United"
But if you use some specific method on one of the objects in the pairs I'll be better if you make another map:
private Map<String, Integer> team1 = new HashMap<String, Integer>();
private Map<Integer, String> team1Keys = new HashMap<Integer, String>();
and then
team1.put("United", 5);
team1Keys.put(5, "United");
and remember, keep it simple ;)
The easiest way would be to use a GUI:
For Gnome use gnome-schedule (universe)
sudo apt-get install gnome-schedule
For KDE use kde-config-cron
It should be pre installed on Kubuntu
But if you use a headless linux or don´t want GUI´s you may use:
crontab -e
If you type it into Terminal you´ll get a table.
You have to insert your cronjobs now.
Format a job like this:
* * * * * YOURCOMMAND
- - - - -
| | | | |
| | | | +----- Day in Week (0 to 7) (Sunday is 0 and 7)
| | | +------- Month (1 to 12)
| | +--------- Day in Month (1 to 31)
| +----------- Hour (0 to 23)
+------------- Minute (0 to 59)
There are some shorts, too (if you don´t want the *):
@reboot --> only once at startup
@daily ---> once a day
@midnight --> once a day at midnight
@hourly --> once a hour
@weekly --> once a week
@monthly --> once a month
@annually --> once a year
@yearly --> once a year
If you want to use the shorts as cron (because they don´t work or so):
@daily --> 0 0 * * *
@midnight --> 0 0 * * *
@hourly --> 0 * * * *
@weekly --> 0 0 * * 0
@monthly --> 0 0 1 * *
@annually --> 0 0 1 1 *
@yearly --> 0 0 1 1 *
According to the documentation:
BigInteger(String val)
Translates the decimal String representation of a BigInteger into a BigInteger.
It means that you can use a String
to initialize a BigInteger
object, as shown in the following snippet:
sum = sum.add(new BigInteger(newNumber));
Django 2.2 version now has a bulk_update
method (release notes).
https://docs.djangoproject.com/en/stable/ref/models/querysets/#bulk-update
Example:
# get a pk: record dictionary of existing records
updates = YourModel.objects.filter(...).in_bulk()
....
# do something with the updates dict
....
if hasattr(YourModel.objects, 'bulk_update') and updates:
# Use the new method
YourModel.objects.bulk_update(updates.values(), [list the fields to update], batch_size=100)
else:
# The old & slow way
with transaction.atomic():
for obj in updates.values():
obj.save(update_fields=[list the fields to update])
Take a look there : http://developer.android.com/guide/topics/intents/intents-filters.html
DO you have update your manifest file in order to give call rights ?

Perhaps this helps someone.
If you want to avoid changing syntax to solve this problem, try this:
Update your MySQL to version 5.5 or greater.
This resolved the problem for me.
To download ISIN code data the only place I see this is on the ISIN organizations website, www.isin.org. try http://isin.org, they should have a function where you can easily download.
Today. I have same problem... my solution:
1) check inode: df -i
I saw:
root@vm22433:/etc/mysql# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
udev 124696 304 124392 1% /dev
tmpfs 127514 452 127062 1% /run
/dev/vda1 1969920 1969920 0 100% /
tmpfs 127514 1 127513 1% /dev/shm
tmpfs 127514 3 127511 1% /run/lock
tmpfs 127514 15 127499 1% /sys/fs/cgroup
tmpfs 127514 12 127502 1% /run/user/1002
2) I began to look what folders use the maximum number of inods:
for i in /*; do echo $i; find $i |wc -l; done
soon I found in /home/tomnolane/tmp folder, which contained a huge number of files.
3) I removed /home/tomnolane/tmp folder PROFIT.
4) checked:
Filesystem Inodes IUsed IFree IUse% Mounted on
udev 124696 304 124392 1% /dev
tmpfs 127514 454 127060 1% /run
/dev/vda1 1969920 450857 1519063 23% /
tmpfs 127514 1 127513 1% /dev/shm
tmpfs 127514 3 127511 1% /run/lock
tmpfs 127514 15 127499 1% /sys/fs/cgroup
tmpfs 127514 12 127502 1% /run/user/1002
it's ok.
5) restart mysql service
- it's ok!!!!
I've also had this error when trying to pull the changes into a branch which is not created from the upstream branch from which I'm trying to pull.
Eg - This creates a new branch matching night-version
of upstream
git checkout upstream/night-version -b testnightversion
This creates a branch testmaster
in local which matches the master
branch of upstream.
git checkout upstream/master -b testmaster
Now if I try to pull the changes of night-version
into testmaster
branch leads to this error.
git pull upstream night-version //while I'm in `master` cloned branch
I managed to solve this by navigating to proper branch and pull the changes.
git checkout testnightversion
git pull upstream night-version // works fine.
Use the zipfile
module. To extract a file from a URL, you'll need to wrap the result of a urlopen
call in a BytesIO
object. This is because the result of a web request returned by urlopen
doesn't support seeking:
from urllib.request import urlopen
from io import BytesIO
from zipfile import ZipFile
zip_url = 'http://example.com/my_file.zip'
with urlopen(zip_url) as f:
with BytesIO(f.read()) as b, ZipFile(b) as myzipfile:
foofile = myzipfile.open('foo.txt')
print(foofile.read())
If you already have the file downloaded locally, you don't need BytesIO
, just open it in binary mode and pass to ZipFile
directly:
from zipfile import ZipFile
zip_filename = 'my_file.zip'
with open(zip_filename, 'rb') as f:
with ZipFile(f) as myzipfile:
foofile = myzipfile.open('foo.txt')
print(foofile.read().decode('utf-8'))
Again, note that you have to open
the file in binary ('rb'
) mode, not as text or you'll get a zipfile.BadZipFile: File is not a zip file
error.
It's good practice to use all these things as context managers with the with
statement, so that they'll be closed properly.
The w3 org said:
By default, SGML requires that all attribute values be delimited using either double quotation marks (ASCII decimal 34) or single quotation marks (ASCII decimal 39). Single quote marks can be included within the attribute value when the value is delimited by double quote marks, and vice versa. Authors may also use numeric character references to represent double quotes (
"
) and single quotes ('
). For double quotes authors can also use the character entity reference"
.
So... seems to be no difference. Only depends on your style.
You have to do this:
class Bar : public Foo
{
// ...
}
The default inheritance type of a class
in C++ is private
, so any public
and protected
members from the base class are limited to private
. struct
inheritance on the other hand is public
by default.
NSMutableDictionary *contentDictionary = [[NSMutableDictionary alloc]init];
[contentDictionary setValue:@"a" forKey:@"b"];
[contentDictionary setValue:@"c" forKey:@"d"];
NSData *data = [NSJSONSerialization dataWithJSONObject:contentDictionary options:NSJSONWritingPrettyPrinted error:nil];
NSString *jsonStr = [[NSString alloc] initWithData:data
encoding:NSUTF8StringEncoding];
The date/time in the datebase won't be a formatted version at all. It'll just be the date/time itself. How you display that date/time when you extract the value from the database is a different matter. I strongly suspect you really just want:
model.Returndate = DateTime.Now.Date;
or possibly
model.Returndate = DateTime.UtcNow.Date;
Yes, if you look at the database using SQL Server Studio or whatever, you'll now see midnight - but that's irrelevant, and when you fetch the date out of the database and display it to a user, then you can apply the relevant format.
EDIT: In regard to your edited question, the problem isn't with the model - it's how you specify the view. You should use something like:
@Html.EditorFor(model => model.Returndate.Date.ToString("d"))
where d
is the standard date and time format specifier for the short date pattern (which means it'll take the current cultural settings into account).
That's the bit I've been saying repeatedly - that when you display the date/time to the user, that's the time to format it as a date without a time.
EDIT: If this doesn't work, there should be a way of decorating the model or view with a format string - or something like that. I'm not really an MVC person, but it feels like there ought to be a good way of doing this declaratively...
In case others may find this useful: I found that by adding an initial empty cell to my list of search terms, a zero value will be returned instead of error.
={INDEX(SearchTerms!$A$1:$A$38,MAX(IF(ISERROR(SEARCH(SearchTerms!$A$1:$A$38,SearchCell)),0,1)*((SearchTerms!$B$1:$B$38)+1)))}
NB: Column A has the search terms, B is the row number index.
I saw that no one had used the slice method, so here I put my 2 cents here.
df["<col_name>"].str.slice(stop=5)
df["<col_name>"].str.slice(start=6)
This method will create two new columns.
You need both a value and a field to assign it to. The value is TableField + 1
, so the assignment is:
SET TableField = TableField + 1
If none of the solutions above work, the output of ps
isn't your problem. Maybe you need to set putty to wrap long lines?
Otherwise, we need more information.
With C# 3.0 and System.Data.DataSetExtensions.dll,
List<DataRow> rows = table.Rows.Cast<DataRow>().ToList();
You might also want to look at the gmpy module. It is an interface between Python and the GMP multiple-precision library. gmpy provides an invert function that does exactly what you need:
>>> import gmpy
>>> gmpy.invert(1234567, 1000000007)
mpz(989145189)
Updated answer
As noted by @hyh , the gmpy.invert()
returns 0 if the inverse does not exist. That matches the behavior of GMP's mpz_invert()
function. gmpy.divm(a, b, m)
provides a general solution to a=bx (mod m)
.
>>> gmpy.divm(1, 1234567, 1000000007)
mpz(989145189)
>>> gmpy.divm(1, 0, 5)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ZeroDivisionError: not invertible
>>> gmpy.divm(1, 4, 8)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ZeroDivisionError: not invertible
>>> gmpy.divm(1, 4, 9)
mpz(7)
divm()
will return a solution when gcd(b,m) == 1
and raises an exception when the multiplicative inverse does not exist.
Disclaimer: I'm the current maintainer of the gmpy library.
Updated answer 2
gmpy2 now properly raises an exception when the inverse does not exists:
>>> import gmpy2
>>> gmpy2.invert(0,5)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ZeroDivisionError: invert() no inverse exists
If you're a heavy visual studio user, you can simply open your preference settings and add the following to your settings.json:
...
"editor.formatOnSave": true,
"editor.codeActionsOnSave": {
"source.organizeImports": true
}
....
Hopefully this can be helpful!
Well, by IP is faster.
Basically, when you call by server name, it is converted to original IP.
But it would be difficult to memorize an IP, for this reason the domain name was created.
Personally I use http://localhost
instead of http://127.0.0.1
or http://username
.
This works for me
$('ul.questions li a').click(function(event) {
event.preventDefault();
$('.tab').hide();
window.location.hash = this.hash;
$($(this).attr('href')).fadeIn('slow');
});

An easy to use network fault injection tool is Saboteur. It can simulate:
- Total network partition
- Remote service dead (not listening on the expected port)
- Delays
- Packet loss -TCP connection timeout (as often happens when two systems are separated by a stateful firewall)
I'm new to SQL, but came across this issue in a course I was taking and found that assigning the query to the project specifically helped to eliminate the multi-part error. For example the project I created was CTU SQL Project so I made sure I started my script with USE [CTU SQL Project] as my first line like below.
USE [CTU SQL Project]
SELECT Advisors.First_Name, Advisors.Last_Name...and so on.
Is something like this what you're looking for?
def write_vars_to_file(f, **vars):
for name, val in vars.items():
f.write("%s = %s\n" % (name, repr(val)))
Usage:
>>> import sys
>>> write_vars_to_file(sys.stdout, dict={'one': 1, 'two': 2})
dict = {'two': 2, 'one': 1}
If you are facing this issue in a .ts file which is only there to provide you some constant values, then you can just
rename your .ts file to .js file
and the error will not come again.
For those that are on Mac OSX, perhaps the easiest way to work around this is to use ditto (only on the mac, AFAIK, though). It will create the directory structure that is missing in the destination.
For instance, I did this
ditto 6.3.2/6.3.2/macosx/bin/mybinary ~/work/binaries/macosx/6.3.2/
where ~/work
did not contain the binaries directory before I ran the command.
I thought rsync should work similarly, but it seems it only works for one level of missing directories. That is,
rsync 6.3.3/6.3.3/macosx/bin/mybinary ~/work/binaries/macosx/6.3.3/
worked, because ~/work/binaries/macosx existed but not ~/work/binaries/macosx/6.3.2/
try this, hope it will help you to get the current location, every time the location changes.
public class MyClass implements LocationListener {
double currentLatitude, currentLongitude;
public void onLocationChanged(Location location) {
currentLatitude = location.getLatitude();
currentLongitude = location.getLongitude();
}
}
Wanting to initalize an array of fixed size is a perfectly acceptable thing to do in any programming language; it isn't like the programmer wants to put a break statement in a while(true) loop. Believe me, especially if the elements are just going to be overwritten and not merely added/subtracted, like is the case of many dynamic programming algorithms, you don't want to mess around with append statements and checking if the element hasn't been initialized yet on the fly (that's a lot of code gents).
object = [0 for x in range(1000)]
This will work for what the programmer is trying to achieve.
In the case that you not only want to exclude a list of special characters, but to exclude all characters that are not letters or numbers, I would suggest that you use a char type comparison approach.
For each character in the String, I would check if the unicode character is between "A" and "Z", between "a" and "z" or between "0" and "9". This is the vba code:
Function cleanString(text As String) As String
Dim output As String
Dim c 'since char type does not exist in vba, we have to use variant type.
For i = 1 To Len(text)
c = Mid(text, i, 1) 'Select the character at the i position
If (c >= "a" And c <= "z") Or (c >= "0" And c <= "9") Or (c >= "A" And c <= "Z") Then
output = output & c 'add the character to your output.
Else
output = output & " " 'add the replacement character (space) to your output
End If
Next
cleanString = output
End Function
The Wikipedia list of Unicode characers is a good quick-start if you want to customize this function a little more.
This solution has the advantage to be functionnal even if the user finds a way to introduce new special characters. It also faster than comparing two lists together.
You can make the border transparent. In this way it exists, but is invisible, so it doesn't push anything around:
.jobs .item {
background: #eee;
border: 1px solid transparent;
}
.jobs .item:hover {
background: #e1e1e1;
border: 1px solid #d0d0d0;
}
_x000D_
<div class="jobs">
<div class="item">Item</div>
</div>
_x000D_
For elements that already have a border, and you don't want them to move, you can use negative margins:
.jobs .item {
background: #eee;
border: 1px solid #d0d0d0;
}
.jobs .item:hover {
background: #e1e1e1;
border: 3px solid #d0d0d0;
margin: -2px;
}
_x000D_
<div class="jobs">
<div class="item">Item</div>
</div>
_x000D_
Another possible trick for adding width to an existing border is to add a box-shadow
with the spread attribute of the desired pixel width.
.jobs .item {
background: #eee;
border: 1px solid #d0d0d0;
}
.jobs .item:hover {
background: #e1e1e1;
box-shadow: 0 0 0 2px #d0d0d0;
}
_x000D_
<div class="jobs">
<div class="item">Item</div>
</div>
_x000D_
You could try changing the button attribute like this:
element.setAttribute( "onClick", "javascript: Boo();" );
The best option is probably to use a lambda expression that closes over the variables you want to display.
However, be careful in this case, especially if you're calling this in a loop. (I mention this since your variable is an "ID", and this is common in this situation.) If you close over the variable in the wrong scope, you can get a bug. For details, see Eric Lippert's post on the subject. This typically requires making a temporary:
foreach(int id in myIdsToCheck)
{
int tempId = id; // Make a temporary here!
Task.Factory.StartNew( () => CheckFiles(tempId, theBlockingCollection),
cancelCheckFile.Token,
TaskCreationOptions.LongRunning,
TaskScheduler.Default);
}
Also, if your code is like the above, you should be careful with using the LongRunning
hint - with the default scheduler, this causes each task to get its own dedicated thread instead of using the ThreadPool. If you're creating many tasks, this is likely to have a negative impact as you won't get the advantages of the ThreadPool. It's typically geared for a single, long running task (hence its name), not something that would be implemented to work on an item of a collection, etc.
While the methods above might work, here is a very good method.
Extend the core controller with a MY controller, then extend this MY controller for all your other controllers. For example, you could have:
class MY_Controller extends CI_Controller {
public function is_logged()
{
//Your code here
}
public function logout()
{
//Your code here
}
}
Then your other controllers could then extend this as follows:
class Another_Controller extends MY_Controller {
public function show_home()
{
if (!$this->is_logged()) {
return false;
}
}
public function logout()
{
$this->logout();
}
}
In my case a previous run of my app from VS reserved the URL. I could see this by running in a console:
netsh http show urlacl
to delete this reservation i ran this in an elevated console:
netsh http delete urlacl http://127.0.0.1:10002/
I found these steps here solved my problem.
I'm using VS2013
I think gitready is a great starting point. I'm using git for a project now and that site pretty much got the ball rolling for me.

You can try server.connection-timeout=5000
in your application.properties. From the official documentation:
server.connection-timeout= # Time in milliseconds that connectors will wait for another HTTP request before closing the connection. When not set, the connector's container-specific default will be used. Use a value of -1 to indicate no (i.e. infinite) timeout.
On the other hand, you may want to handle timeouts on the client side using Circuit Breaker pattern as I have already described in my answer here: https://stackoverflow.com/a/44484579/2328781
josonify works..but if you intend to just pass an array without the 'results' key, you can use json library from python. The following conversion works for me..
import json
@app.route('/test/json')
def test_json():
list = [
{'a': 1, 'b': 2},
{'a': 5, 'b': 10}
]
return json.dumps(list))
Try this code You may want something like this
<button class="normal" id="myButton"
value="Hover" onmouseover="mouseOver()"
onmouseout="mouseOut()">Some text</button>
Then on your .js file enter this.Make sure your html is connected to your .js
var tag=document.getElementById("myButton");
function mouseOver() {
tag.style.background="yellow";
};
function mouseOut() {
tag.style.background="white";
};
Sorry for resurrection. You could use child_process module to execute external js files in node.js
var child_process = require('child_process');
//EXECUTE yourExternalJsFile.js
child_process.exec('node yourExternalJsFile.js', (error, stdout, stderr) => {
console.log(`${stdout}`);
console.log(`${stderr}`);
if (error !== null) {
console.log(`exec error: ${error}`);
}
});
if var == 'stringone' or var == 'stringtwo':

The maven add dependency is actually from the maven indexes. If the indexes is up to date, the result should be from there.
If you go to the maven repository, then select global repository, you should see a central ... tab, and select that, there should be a list of folders, and you should be able to see all the indexes from there. If not, then it means you didn't get the full index, then you can right click that and enable full index.
Another thing I annoyed me most is even I did everything, it still not showing anything when I type "spring". This is actually where I did wrong. If you just type some additional text "springframework", BOOM, the result is there.
Conditional imports could also be achieved with a ternary and require()
s:
const logger = DEBUG ? require('dev-logger') : require('logger');
This example was taken from the ES Lint global-require docs: https://eslint.org/docs/rules/global-require
Having had an experience with both frameworks recently, I thought I can share my views on each frameworks.
I was asked to evaluate the logging frameworks for an existing web application, I narrowed down my choices to NLog (v2.0) and log4net (v1.2.11) after going through various online forums. Here are my findings:
Setting/starting up with NLog is dead easy. You go through the Getting started tutorial on their website and you are done. You get a fair idea, how thing might be with nlog. Config file is so intuitive that anyone can understand the config. For example: if you want to set the internal logging on, you set the flag in Nlog config file's header node, which is where you would expect it to be. In log4net, you set different flags in web.config's appSettings section.
In log4net, internal logging doesnt output timestamp which is annoying. In Nlog, you get a nice log with timestamps. I found it very useful in my evaluations.
Filters in log4net - You better check my this question - log4net filter - how to write AND filter to ignore log messages and if you find an answer/solution for this, please let me know. I understand, there is a workaround for this question, as you can write your own custom filter. But something which is not easily available in log4net.
Performance - I logged around 3000 log messages to database using a stored procedure. I used simple for loop (int i=0; i<3000; i++... to log the same message 3000 times. For the writes: log4net AdoAppender took almost double the time than NLog.
Log4net doesnt support asynchronous appender.
It was sufficient comparison for me to choose NLog as the logging framework. :)
%timeit
is an ipython magic function, which can be used to time a particular piece of code (A single execution statement, or a single method).
From the docs:
%timeit
Time execution of a Python statement or expression Usage, in line mode: %timeit [-n<N> -r<R> [-t|-c] -q -p<P> -o] statement
To use it, for example if we want to find out whether using xrange
is any faster than using range
, you can simply do:
In [1]: %timeit for _ in range(1000): True
10000 loops, best of 3: 37.8 µs per loop
In [2]: %timeit for _ in xrange(1000): True
10000 loops, best of 3: 29.6 µs per loop
And you will get the timings for them.
The major advantage of %timeit
are:
that you don't have to import timeit.timeit
from the standard library, and run the code multiple times to figure out which is the better approach.
%timeit will automatically calculate number of runs required for your code based on a total of 2 seconds execution window.
You can also make use of current console variables without passing the whole code snippet as in case of timeit.timeit
to built the variable that is built in an another environment that timeit works.
You should simply install request
locally within your project.
Just cd
to the folder containing your js file and run
npm install request

The facebook acess token looks similar too "1249203702|2.h1MTNeLqcLqw__.86400.129394400-605430316|-WE1iH_CV-afTgyhDPc"
if you extract the middle part by using | to split you get
2.h1MTNeLqcLqw__.86400.129394400-605430316
then split again by -
the last part 605430316 is the user id.
Here is the C# code to extract the user id from the access token:
public long ParseUserIdFromAccessToken(string accessToken)
{
Contract.Requires(!string.isNullOrEmpty(accessToken);
/*
* access_token:
* 1249203702|2.h1MTNeLqcLqw__.86400.129394400-605430316|-WE1iH_CV-afTgyhDPc
* |_______|
* |
* user id
*/
long userId = 0;
var accessTokenParts = accessToken.Split('|');
if (accessTokenParts.Length == 3)
{
var idPart = accessTokenParts[1];
if (!string.IsNullOrEmpty(idPart))
{
var index = idPart.LastIndexOf('-');
if (index >= 0)
{
string id = idPart.Substring(index + 1);
if (!string.IsNullOrEmpty(id))
{
return id;
}
}
}
}
return null;
}
WARNING: The structure of the access token is undocumented and may not always fit the pattern above. Use it at your own risk.
Update Due to changes in Facebook. the preferred method to get userid from the encrypted access token is as follows:
try
{
var fb = new FacebookClient(accessToken);
var result = (IDictionary<string, object>)fb.Get("/me?fields=id");
return (string)result["id"];
}
catch (FacebookOAuthException)
{
return null;
}
The External Dependencies folder is populated by IntelliSense: the contents of the folder do not affect the build at all (you can in fact disable the folder in the UI).
You need to actually include the header (using a #include
directive) to use it. Depending on what that header is, you may also need to add its containing folder to the "Additional Include Directories" property and you may need to add additional libraries and library folders to the linker options; you can set all of these in the project properties (right click the project, select Properties). You should compare the properties with those of the project that does build to determine what you need to add.
OK. This is the "most elegant" solution I could come up with on the fly:
boolean allTrue = !Arrays.toString(myArray).contains("f");
Hope that helps!
So i had a adifferent case where i needed to assign values before running a session, So this was the easiest way to do that:
other_variable = tf.get_variable("other_variable", dtype=tf.int32,
initializer=tf.constant([23, 42]))
here i'm creating a variable as well as assigning it values at the same time
private static byte[] charArrayToByteArray(char[] c_array) {
byte[] b_array = new byte[c_array.length];
for(int i= 0; i < c_array.length; i++) {
b_array[i] = (byte)(0xFF & (int)c_array[i]);
}
return b_array;
}
You could also use the php native funcion get_browser()

A reference can be thought of as a constant pointer (not to be confused with a pointer to a constant value!) with automatic indirection, ie the compiler will apply the *
operator for you.
All references must be initialized with a non-null value or compilation will fail. It's neither possible to get the address of a reference - the address operator will return the address of the referenced value instead - nor is it possible to do arithmetics on references.
C programmers might dislike C++ references as it will no longer be obvious when indirection happens or if an argument gets passed by value or by pointer without looking at function signatures.
C++ programmers might dislike using pointers as they are considered unsafe - although references aren't really any safer than constant pointers except in the most trivial cases - lack the convenience of automatic indirection and carry a different semantic connotation.
Consider the following statement from the C++ FAQ:
Even though a reference is often implemented using an address in the underlying assembly language, please do not think of a reference as a funny looking pointer to an object. A reference is the object. It is not a pointer to the object, nor a copy of the object. It is the object.
But if a reference really were the object, how could there be dangling references? In unmanaged languages, it's impossible for references to be any 'safer' than pointers - there generally just isn't a way to reliably alias values across scope boundaries!
Coming from a C background, C++ references may look like a somewhat silly concept, but one should still use them instead of pointers where possible: Automatic indirection is convenient, and references become especially useful when dealing with RAII - but not because of any perceived safety advantage, but rather because they make writing idiomatic code less awkward.
RAII is one of the central concepts of C++, but it interacts non-trivially with copying semantics. Passing objects by reference avoids these issues as no copying is involved. If references were not present in the language, you'd have to use pointers instead, which are more cumbersome to use, thus violating the language design principle that the best-practice solution should be easier than the alternatives.
No, but you can use the s///
substitution operator and the \s
whitespace assertion to get the same result.
As mentioned by the accepted answer, you can't exclude patterns with glob, so the following is a method to filter your glob result.
The accepted answer is probably the best pythonic way to do things but if you think list comprehensions look a bit ugly and want to make your code maximally numpythonic anyway (like I did) then you can do this (but note that this is probably less efficient than the list comprehension method):
import glob
data_files = glob.glob("path_to_files/*.fits")
light_files = np.setdiff1d( data_files, glob.glob("*BIAS*"))
light_files = np.setdiff1d(light_files, glob.glob("*FLAT*"))
(In my case, I had some image frames, bias frames, and flat frames all in one directory and I just wanted the image frames)
I found a solution for how to set a global variable in a mailinglist posting via assign:
a <- "old"
test <- function () {
assign("a", "new", envir = .GlobalEnv)
}
test()
a # display the new value
Following the thread from @James Cropcho's answer, I landed on the following which I found to be super easy to use. It is a binary tool, which is exactly what I was looking for: mongoeye.
Using this tool it took about 2 minutes to get my schema exported from command line.
take a look at shutil
. shutil.copyfile(src, dst)
will copy a file to another file.
Note that shutil.copyfile
will not create directories that do not already exist. for that, use os.makedirs
If you just need to test some of the concrete methods without touching any of the abstracts, you can use CALLS_REAL_METHODS
(see Morten's answer), but if the concrete method under test calls some of the abstracts, or unimplemented interface methods, this won't work -- Mockito will complain "Cannot call real method on java interface."
(Yes, it's a lousy design, but some frameworks, e.g. Tapestry 4, kind of force it on you.)
The workaround is to reverse this approach -- use the ordinary mock behavior (i.e., everything's mocked/stubbed) and use doCallRealMethod()
to explicitly call out the concrete method under test. E.g.
public abstract class MyClass {
@SomeDependencyInjectionOrSomething
public abstract MyDependency getDependency();
public void myMethod() {
MyDependency dep = getDependency();
dep.doSomething();
}
}
public class MyClassTest {
@Test
public void myMethodDoesSomethingWithDependency() {
MyDependency theDependency = mock(MyDependency.class);
MyClass myInstance = mock(MyClass.class);
// can't do this with CALLS_REAL_METHODS
when(myInstance.getDependency()).thenReturn(theDependency);
doCallRealMethod().when(myInstance).myMethod();
myInstance.myMethod();
verify(theDependency, times(1)).doSomething();
}
}
Updated to add:
For non-void methods, you'll need to use thenCallRealMethod()
instead, e.g.:
when(myInstance.myNonVoidMethod(someArgument)).thenCallRealMethod();
Otherwise Mockito will complain "Unfinished stubbing detected."
The problem is that you are using the bitwise or operator: |
. If you use the logical or operator, ||
, your code will work fine.

Difference between & and && in Java?
In addition to the already posted answer, I thought I should share a handy trick I use to load all the DLL functions into the program through function pointers, without writing a separate GetProcAddress call for each and every function. I also like to call the functions directly as attempted in the OP.
Start by defining a generic function pointer type:
typedef int (__stdcall* func_ptr_t)();
What types that are used aren't really important. Now create an array of that type, which corresponds to the amount of functions you have in the DLL:
func_ptr_t func_ptr [DLL_FUNCTIONS_N];
In this array we can store the actual function pointers that point into the DLL memory space.
Next problem is that GetProcAddress
expects the function names as strings. So create a similar array consisting of the function names in the DLL:
const char* DLL_FUNCTION_NAMES [DLL_FUNCTIONS_N] =
{
"dll_add",
"dll_subtract",
"dll_do_stuff",
...
};
Now we can easily call GetProcAddress() in a loop and store each function inside that array:
for(int i=0; i<DLL_FUNCTIONS_N; i++)
{
func_ptr[i] = GetProcAddress(hinst_mydll, DLL_FUNCTION_NAMES[i]);
if(func_ptr[i] == NULL)
{
// error handling, most likely you have to terminate the program here
}
}
If the loop was successful, the only problem we have now is calling the functions. The function pointer typedef from earlier isn't helpful, because each function will have its own signature. This can be solved by creating a struct with all the function types:
typedef struct
{
int (__stdcall* dll_add_ptr)(int, int);
int (__stdcall* dll_subtract_ptr)(int, int);
void (__stdcall* dll_do_stuff_ptr)(something);
...
} functions_struct;
And finally, to connect these to the array from before, create a union:
typedef union
{
functions_struct by_type;
func_ptr_t func_ptr [DLL_FUNCTIONS_N];
} functions_union;
Now you can load all the functions from the DLL with the convenient loop, but call them through the by_type
union member.
But of course, it is a bit burdensome to type out something like
functions.by_type.dll_add_ptr(1, 1);
whenever you want to call a function.
As it turns out, this is the reason why I added the "ptr" postfix to the names: I wanted to keep them different from the actual function names. We can now smooth out the icky struct syntax and get the desired names, by using some macros:
#define dll_add (functions.by_type.dll_add_ptr)
#define dll_subtract (functions.by_type.dll_subtract_ptr)
#define dll_do_stuff (functions.by_type.dll_do_stuff_ptr)
And voilà, you can now use the function names, with the correct type and parameters, as if they were statically linked to your project:
int result = dll_add(1, 1);
Disclaimer: Strictly speaking, conversions between different function pointers are not defined by the C standard and not safe. So formally, what I'm doing here is undefined behavior. However, in the Windows world, function pointers are always of the same size no matter their type and the conversions between them are predictable on any version of Windows I've used.
Also, there might in theory be padding inserted in the union/struct, which would cause everything to fail. However, pointers happen to be of the same size as the alignment requirement in Windows. A static_assert
to ensure that the struct/union has no padding might be in order still.
You can also use the following alternative realpath.
Create a file called path.php
Put the following code inside by specifying the name of the created file.
<?php
echo realpath('path.php');
?>
A php file that you can move to all your folders to always have the absolute path from where the executed file is located.

see all solutions: my project is just use xib, so, the solution with storyboard not worked for me. self.edgesForExtendedLayout = UIRectEdgeNone; just works for controller if navigationbar is visible. but if your view is just have status bar, that will not work. so i combine two conditons.
- (void) viewDidLayoutSubviews {
float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
if (systemVersion >= 7.0f) {
CGRect bounds = self.view.bounds;
if(self.navigationController == nil || self.navigationController.isNavigationBarHidden == YES){
bounds.origin.y -= 20.0;
[self.view setBounds:bounds];
}
else{
self.edgesForExtendedLayout = UIRectEdgeNone;
}
}
help this works.

In order to get the desired result, you must set "box-sizing: border-box" vs. the default which is "box-sizing: content-box". This is precisely the issue you are referring to (From MDN):
This is the initial and default value as specified by the CSS standard. The width and height properties are measured including only the content, but not the padding, border or margin.
The width and height properties include the content, the padding and border, but not the margin."
Reference: https://developer.mozilla.org/en-US/docs/Web/CSS/box-sizing
Compatibility for this CSS is good.
Start with:
find . -name '*.log.*.zip' -a -mtime +1
You may not need a regex, try:
find . -name '*.log.*-*-*.zip' -a -mtime +1
You will want the +1 in order to match 1, 2, 3 ...
Don't forget to inject $location
into controller.
