You are still in the context of your CategoryController
even though you're loading a PartialView
from your Views/News
folder.
Below Test Init will also do the job.

HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));

I found a solution for ajax issue noted by Lion_cl.
global.asax:
protected void Application_Error()
{
if (HttpContext.Current.Request.IsAjaxRequest())
{
HttpContext ctx = HttpContext.Current;
ctx.Response.Clear();
RequestContext rc = ((MvcHandler)ctx.CurrentHandler).RequestContext;
rc.RouteData.Values["action"] = "AjaxGlobalError";
// TODO: distinguish between 404 and other errors if needed
rc.RouteData.Values["newActionName"] = "WrongRequest";
rc.RouteData.Values["controller"] = "ErrorPages";
IControllerFactory factory = ControllerBuilder.Current.GetControllerFactory();
IController controller = factory.CreateController(rc, "ErrorPages");
controller.Execute(rc);
ctx.Server.ClearError();
}
}
ErrorPagesController
public ActionResult AjaxGlobalError(string newActionName)
{
return new AjaxRedirectResult(Url.Action(newActionName), this.ControllerContext);
}
AjaxRedirectResult
public class AjaxRedirectResult : RedirectResult
{
public AjaxRedirectResult(string url, ControllerContext controllerContext)

{
ExecuteResult(controllerContext);
}
public override void ExecuteResult(ControllerContext context)
{
if (context.RequestContext.HttpContext.Request.IsAjaxRequest())
{
JavaScriptResult result = new JavaScriptResult()
{
Script = "try{history.pushState(null,null,window.location.href);}catch(err){}window.location.replace('" + UrlHelper.GenerateContentUrl(this.Url, context.HttpContext) + "');"
};
result.ExecuteResult(context);
}
else
{
base.ExecuteResult(context);
}
}
}
AjaxRequestExtension

The config section seems sound as it works if when pages are accessed normally. I've tried the other configurations suggested but the problem is still there.
I doubt the problem is in the Session provider since it works without the routing.
Ultimately, we are trying to get to this.
<div style="display: flex; justify-content: center;">

By deleting all emulator, sometime memory will not be reduce to our expectation. So open below mention path in you c drive
C:\Users{Username}.android\avd
In this avd folder, you can able to see all the avd's which you created earlier. So you need to delete all avd's that will remove all the unused spaces grab by your emulator's. Than create the fresh emulator for you works.
Don't do this!
Stay away from putting the events inline with the elements! If you don't, you're missing the point of JQuery (or one of the biggest ones at least).
The reason why it's easy to define click() handlers one way and not the other is that the other way is simply not desirable. Since you're just learning JQuery, stick to the convention. Now is not the time in your learning curve for JQuery to decide that everyone else is doing it wrong and you have a better way!
this use for Scope just like this
<script type="text/javascript" language="javascript">
$('#tbleName tbody tr').each(function{
var txt='';
txt += $(this).find("td").eq(0).text();
\\same as above but synatx different
var txt1='';
txt1+=$('#tbleName tbody tr').eq(0).text();
alert(txt1)
});
</script>
value of txt1 and txt is same in Above example $(this)=$('#tbleName tbody tr') is Same
No, I don't think there is. Unfortunately, you're stuck calling getApplicationContext()
from Activity
or one of the other subclasses of Context
. Also, this question is somewhat related.
After installing Anaconda3 on your system you need to add Anaconda to the PATH environment variable. This will allow you to access Anaconda with the 'conda' command from cmd.exe or PowerShell.
The link I provided below go through the three major issues with not recognized error. Which are:
My issue was resolved following the steps for issue #2 Environment PATH is incorrectly added. I did not have all three file paths in my variable environment.
Only call time pass-by-reference is removed. So change:
call_user_func($func, &$this, &$client ...
To this:
call_user_func($func, $this, $client ...
&$this
should never be needed after PHP4 anyway period.
If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {
)
Figure out what keys are in the $output array, and fill the missing ones in with empty strings.
$keys = array_keys($output);
$desired_keys = array('author', 'new_icon', 'admin_link', 'etc.');
foreach($desired_keys as $desired_key){
if(in_array($desired_key, $keys)) continue; // already set
$output[$desired_key] = '';
}
Use sed's substitution: sed 's/"//g'
s/X/Y/
replaces X with Y.
g
means all occurrences should be replaced, not just the first one.
Do you want iteration? itertools.combinations. Common usage:
>>> import itertools
>>> itertools.combinations('abcd',2)
<itertools.combinations object at 0x01348F30>
>>> list(itertools.combinations('abcd',2))
[('a', 'b'), ('a', 'c'), ('a', 'd'), ('b', 'c'), ('b', 'd'), ('c', 'd')]
>>> [''.join(x) for x in itertools.combinations('abcd',2)]
['ab', 'ac', 'ad', 'bc', 'bd', 'cd']
If you just need to compute the formula, use math.factorial:
import math
def nCr(n,r):
f = math.factorial
return f(n) / f(r) / f(n-r)
if __name__ == '__main__':
print nCr(4,2)
In Python 3, use the integer division //
instead of /
to avoid overflows:
return f(n) // f(r) // f(n-r)
6
Try this instead:
var myArray = [];
myArray.push({ id: 0, value: 1 });
myArray.push({ id: 2, value: 3 });
or will this not work for your situation?
Its because you have no BEGIN
and END
statements. You shouldn't be seeing the prints, or errors running this statement, only Statement Completed
(or something like that).
If you want to write a loop in Python which prints some integer no etc, then just copy and paste this code, it'll work a lot
# Display Value from 1 TO 3
for i in range(1,4):
print "",i,"value of loop"
# Loop for dictionary data type
mydata = {"Fahim":"Pakistan", "Vedon":"China", "Bill":"USA" }
for user, country in mydata.iteritems():
print user, "belongs to " ,country
The **
syntax tells Python to collect keyword arguments into a dictionary. The save2
is passing it down as a non-keyword argument (a dictionary object). The openX
is not seeing any keyword arguments so the **args
doesn't get used. It's instead getting a third non-keyword argument (the dictionary). To fix that change the definition of the openX
function.
def openX(filename, mode, kwargs):
pass
I can't believe the accepted answer has so many upvotes -- it's a horrible method.
Here's the correct way to do it, with date_trunc:
SELECT date_trunc('month', txn_date) AS txn_month, sum(amount) as monthly_sum
FROM yourtable
GROUP BY txn_month
It's bad practice but you might be forgiven if you use
GROUP BY 1
in a very simple query.
You can also use
GROUP BY date_trunc('month', txn_date)
if you don't want to select the date.
Have you tried:
$ENV{'SCRIPT_NAME'}
or
use FindBin '$Bin';
print "The script is located in $Bin.\n";
It really depends on how it's being called and if it's CGI or being run from a normal shell, etc.
You can use the following code
name ='mypic'
plt.savefig('path_to_file/{}'.format(name))
If you want to save in same folder where your code lies,ignore the path_to_file and just format with name. If you have folder name 'Images' in the just one level outside of your python script, you can use,
name ='mypic'
plt.savefig('Images/{}'.format(name))
The default file type in saving is '.png' file format. If you want to save in loop, then you can use the unique name for each file such as counter of the for loop. If i is the counter,
plt.savefig('Images/{}'.format(i))
Hope this helps.
Try this:
CSS:
#content {
margin: 0 auto;
border: 1px solid red;
width:800px;
position:absolute;
bottom:0px;
top:0px;
overflow:auto
}
HTML:
<body>
<div id="content">
...content goes here...
</div>
<body>
If you don't like absolute positioning in this case, just can play with making a parent and child div to this one, both with position:relative
.
EDIT: Below should work (I just put the css inline for the moment):
<div style="margin:0 auto; width:800px; height:100%; overflow:hidden">
<div style="border: 1px solid red; width:800px; position:absolute; bottom:0px; top:0px; overflow:auto">
...content goes here...
</div>
</div>
To specify a classpath for a single Java process, you can add a classpath option when you run the Java command.
In you command line. Use
java -cp "path/to/your/jar:." main
rather than just
java main
The option tells Java where to search for libraries.
You shouldn't have to care that much. RFC 3339, according to itself, is a set of standards derived from ISO 8601. There's quite a few minute differences though, and they're all outlined in RFC 3339. I could go through them all here, but you'd probably do better just reading the document for yourself in the event you're worried:
Regarding the second question: push_ref takes reference as a parameter, and you cannot have a reference to static const memeber of a class/struct. Once you call static_cast, a temporary variable is created. And a reference to this object can be passed, everything works just fine.
Or at least my colleague who resolved this said so.
This question was asked before Java 7 release but now, there is another possible way using Java 7 (and above) API:
double random = ThreadLocalRandom.current().nextDouble(min, max);
nextDouble
will return a pseudorandom double value between the minimum (inclusive) and the maximum (exclusive). The bounds are not necessarily int
, and can be double
.
listStr = open("file_name","mode")
if "search element" in listStr:
print listStr.index("search element") # This will gives you the line number
I just discovered, after a bit of frustration, that if you're using PairNIC, all you have to do is enable the "Web Forwarding" setting under "Custom DNS" and supply the username.github.io/project address and it will automatically set up both the apex and subdomain records for you. It appears to do exactly what's suggested in the accepted answer. However, it won't let you do the exact same thing by manually adding records. Very strange. Anyway, it took me a while to figure that out, so I thought I'd share to save everyone else the trouble.
After a little more research, I came across iText, a PDF and RTF-file creation API. I think I can use the RTF generation to create a Doc-readable file that can then be edited using Doc and re-saved.
Anyone have any experience with iText, used in this fashion?
A year or so has passed since the question was asked, but I wasn't satisfied with the answers. I fiddled for a while, and here is a code that:

Basically the problem is with file path.
The forward slash in the beginning of the url makes it look for the file at the root. Removing that, it will be a path relative to this css file - like this:
background-image: url(img/debut_dark.png);
If you are using Atom, copying the project path of image sometimes includes forward slash in the copied path so be careful.
Just for reference, under Mac OS X, you can use ? Command+? Shift+? Shift+V to paste without formatting or with the "current" format.
Note: in some apps it's ? Command+? Shift+? Alt+V (see "Edit" Menu ? "Paste and Match Style")
There is a way to do this without installing putty on your Mac. You can easily convert your existing PPK file to a PEM file using PuTTYgen on Windows.
Launch PuTTYgen and then load the existing private key file using the Load button. From the "Conversions" menu select "Export OpenSSH key" and save the private key file with the .pem file extension.
Copy the PEM file to your Mac and set it to be read-only by your user:
chmod 400 <private-key-filename>.pem
Then you should be able to use ssh to connect to your remote server
ssh -i <private-key-filename>.pem username@hostname
In my case here is what I did to cause the diverged message: I did git push
but then did git commit --amend
to add something to the commit message. Then I also did another commit.
So in my case that simply meant origin/master was out of date. Because I knew no-one else was touching origin/master, the fix was trivial: git push -f
(where -f
means force)
Please try this,
SELECT
c.Id,
c.name,

FROM customer c INNER JOIN purchase p
ON c.Id = p.customerId
GROUP BY c.Id,c.name;
Further the previous answers about Dropbox, I implemented the following files tree such as only the PLIST file has to be uploaded to Dropbox:
use the option "Share the link with Dropbox" which copies the link to your clipboard. This link has to be copied into your html file into the itms-servivces URL's query after changing the part www.dropbox.com
by dl.dropboxusercontent.com
. Note I URL encoded the link as suggested by @Mike but I don't test without to do it. Now the itms-services URL's query should look like this: itms-services://?action=download-manifest&url=https%3A%2F%2Fdl.dropboxusercontent.com%2Fs%2FYourShortDropboxLink.plist
upload the html file to your server in http. Note the html file contains both links to ipa and provisioning files.
From now, only the ipa file has to be changed to provide next app versions by OTA to your beta testers. Until Apple is yet changing the security rules.
I join here after the very simple HTML file I'm using:

You aren't actually sending JSON. You are passing an object as the data
, but you need to stringify the object and pass the string instead.
Your dataType: "json"
only tells jQuery that you want it to parse the returned JSON, it does not mean that jQuery will automatically stringify your request data.
Change to:
$.ajax({
type: "POST",
url: hb_base_url + "consumer",
contentType: "application/json",
dataType: "json",
data: JSON.stringify({
first_name: $("#namec").val(),
last_name: $("#surnamec").val(),
email: $("#emailc").val(),
mobile: $("#numberc").val(),
password: $("#passwordc").val()
}),
success: function(response) {
console.log(response);
},
error: function(response) {
console.log(response);
}
});
after you create new user, please don't forget to grant
read/write/root
permission to the user. you can try the
cmd: db.grantRolesToUser('yourNewUsername',[{ role: "root", db: "admin" }])
The use of cron on OS X is discouraged. launchd
is used instead. Try man launchctl
to get started. You have to create special XML files that define your jobs and put them in a special place with certain permissions.
You'll usually just need to figure out launchctl load
http://nb.nathanamy.org/2012/07/schedule-jobs-using-launchd/
Edit
If you really do want to use cron on OS X, check out this answer: https://superuser.com/a/243944/2449
"::" represents scope resolution operator. Functions/methods which have same name can be defined in two different classes. To access the methods of a particular class scope resolution operator is used.
If Not temp_rst1 Is Nothing Then ...

In this case if you have two or more results returned then your result is the last record. So be aware of this if you might have two more records returned as you might not see the expected result.
There is a commercial cross-desktop library for files and folders watching called JxFileWatcher. It can be downloaded from here: http://www.teamdev.com/jxfilewatcher/
Also you can see it in action online: http://www.teamdev.com/jxfilewatcher/onlinedemo/
It's simple-
SELECT empname,
empid,
(SELECT COUNT (profileid)
FROM profile
WHERE profile.empid = employee.empid)
AS number_of_profiles
FROM employee;
It is even simpler when you use a table join like this:
SELECT e.empname, e.empid, COUNT (p.profileid) AS number_of_profiles
FROM employee e LEFT JOIN profile p ON e.empid = p.empid
GROUP BY e.empname, e.empid;
Explanation for the subquery:
Essentially, a subquery in a select
gets a scalar value and passes it to the main query. A subquery in select
is not allowed to pass more than one row and more than one column, which is a restriction. Here, we are passing a count
to the main query, which, as we know, would always be only a number- a scalar value. If a value is not found, the subquery returns null
to the main query. Moreover, a subquery can access columns from the from
clause of the main query, as shown in my query where employee.empid
is passed from the outer query to the inner query.
Edit:
When you use a subquery in a select
clause, Oracle essentially treats it as a left join (you can see this in the explain plan for your query), with the cardinality of the rows being just one on the right for every row in the left.
Explanation for the left join
A left join is very handy, especially when you want to replace the select
subquery due to its restrictions. There are no restrictions here on the number of rows of the tables in either side of the LEFT JOIN
keyword.
For more information read Oracle Docs on subqueries and left join or left outer join.
Seems like you expected the query to return running totals, but it must have given you the same values for both partitions of AccountID
.
To obtain running totals with SUM() OVER ()
, you need to add an ORDER BY
sub-clause after PARTITION BY …
, like this:
SUM(Quantity) OVER (PARTITION BY AccountID ORDER BY ID)
But remember, not all database systems support ORDER BY
in the OVER
clause of a window aggregate function. (For instance, SQL Server didn't support it until the latest version, SQL Server 2012.)
What about position: relative
for the outer div? In the example that hides the inner one. It also won't move it in its layout since you don't specify a top or left.
The literal answer is:
return (value == 1 ? Periods.VariablePeriods : Periods.FixedPeriods);
Note that the inline if statement, just like an if statement, only checks for true or false. If (value == 1) evaluates to false, it might not necessarily mean that value == 2. Therefore it would be safer like this:
return (value == 1
? Periods.VariablePeriods
: (value == 2
? Periods.FixedPeriods
: Periods.Unknown));
If you add more values an inline if will become unreadable and a switch would be preferred:
switch (value)
{
case 1:
return Periods.VariablePeriods;
case 2:
return Periods.FixedPeriods;
}
The good thing about enums is that they have a value, so you can use the values for the mapping, as user854301 suggested. This way you can prevent unnecessary branches thus making the code more readable and extensible.
use fwrite() instead of file_put_contents()
I hope the answers are already posted
I am adding the framework to find multiple words and negate those from dataFrame.
Here 'word1','word2','word3','word4'
= list of patterns to search
df
= DataFrame
column_a
= A column name from from DataFrame df
Search_for_These_values = ['word1','word2','word3','word4']
pattern = '|'.join(Search_for_These_values)
result = df.loc[~(df['column_a'].str.contains(pattern, case=False)]
For example to @Michael Trouw,
inside your controller put this code. this will run everytime when this state is entered or active, you do not need to worry about disabling cache and it's a better approach.
.controller('exampleCtrl',function($scope){
$scope.$on('$ionicView.enter', function(){
// Any thing you can think of
alert("This function just ran away");
});
})
You can have more examples of flexibility like $ionicView.beforeEnter -> which runs before a view is shown. And there are some more to it.

In Objective-C all methods start with either a "-" or "+" character. Example:
@interface MyClass : NSObject
// instance method
- (void) instanceMethod;
+ (void) classMethod;
@end
The "+" and "-" characters specify whether a method is a class method
or an instance method
respectively.
The difference would be clear if we call these methods. Here the methods are declared in MyClass
.
instance method
require an instance of the class:
MyClass* myClass = [[MyClass alloc] init];
[myClass instanceMethod];
Inside MyClass
other methods can call instance methods of MyClass
using self
:
-(void) someMethod
{
[self instanceMethod];
}
But, class methods
must be called on the class itself:
[MyClass classMethod];
Or:
MyClass* myClass = [[MyClass alloc] init];
[myClass class] classMethod];
This won't work:
// Error
[myClass classMethod];
// Error
[self classMethod];
<xsl:value-of select="name(.)" /> : <xsl:value-of select="."/>
For those coming from Ionic or Cordova, you can try the following:
Disconnect your ios devices from the computer before ios cordova build ios --release
(seems to change the targeted device for xcode signing).
Try:
int sum = lst.stream().filter(o -> o.field > 10).mapToInt(o -> o.field).sum();
Try /*string with {}*/ string.trim().equalsIgnoreCase("{}"))
, maybe there is some extra spaces or something
using System;
using System.IO;
// This will get the current WORKING directory (i.e. \bin\Debug)
string workingDirectory = Environment.CurrentDirectory;
// or: Directory.GetCurrentDirectory() gives the same result
// This will get the current PROJECT bin directory (ie ../bin/)
string projectDirectory = Directory.GetParent(workingDirectory).Parent.FullName;
// This will get the current PROJECT directory
string projectDirectory = Directory.GetParent(workingDirectory).Parent.Parent.FullName;
You can force it (browser permitting, I imagine) by inserting line breaks in the HTML source, like this:
<INPUT value="Line 1
Line 2">
Of course working out where to place the line breaks is not necessarily trivial...
If you can use an HTML <BUTTON>
instead of an <INPUT>
, such that the button label is the element's content rather than its value
attribute, placing that content inside a <SPAN>
with a width
attribute that is a few pixels narrower than that of the button seems to do the trick (even in IE6 :-).
Found the script below in this github issue. Works great for me.
#!/usr/bin/env ruby
port = ARGV.first || 3000
system("sudo echo kill-server-on #{port}")
pid = `sudo lsof -iTCP -sTCP:LISTEN -n -P | grep #{port} | awk '{ print $2 }' | head -n 1`.strip
puts "PID: #{pid}"
`kill -9 #{pid}` unless pid.empty?
You can either run it in irb or inside a ruby file.
For the latter, create server_killer.rb
then run it with ruby server_killer.rb
I just ran into the exact same problem while configuring my server 2008 and windows 7 vm's in VMware workstation 9. what helped is disabling the firewall and running the following command at the windows command prompt
netsh firewall set icmpsetting 8 enable
at that point I was able to ping one VM then both once I performed the command on both. this differnce between our scenarios is I have my VM configured using Bridged connections

I was looking for a easy and FAST function with no additional libary to do the job. I tried Nicks solution, but i needed 29,4 sec to "extract" 1195 images of an atlas file. So later i managed this way and needed 2,43 sec to do the same job. Maybe this will be helpful.
// content of the Texture class
public class Texture
{
//name of the texture
public string name { get; set; }
//x position of the texture in the atlas image
public int x { get; set; }
//y position of the texture in the atlas image
public int y { get; set; }
//width of the texture in the atlas image
public int width { get; set; }
//height of the texture in the atlas image
public int height { get; set; }
}
Bitmap atlasImage = new Bitmap(@"C:\somepicture.png");
PixelFormat pixelFormat = atlasImage.PixelFormat;
foreach (Texture t in textureList)
{
try
{
CroppedImage = new Bitmap(t.width, t.height, pixelFormat);
// copy pixels over to avoid antialiasing or any other side effects of drawing
// the subimages to the output image using Graphics
for (int x = 0; x < t.width; x++)
for (int y = 0; y < t.height; y++)
CroppedImage.SetPixel(x, y, atlasImage.GetPixel(t.x + x, t.y + y));
CroppedImage.Save(Path.Combine(workingFolder, t.name + ".png"), ImageFormat.Png);

Look at my project CalcBinding, which provides to you writing complex expressions in Path property value, including static properties, source properties, Math and other. So, you can write this:
<TextBox Text="{c:Binding local:VersionManager.FilterString}"/>
Goodluck!
You can use sed
for this. For example:
$ sed -n '/Feb 23 13:55/,/Feb 23 14:00/p' /var/log/mail.log
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: connect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: lost connection after CONNECT from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: disconnect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie pop3d: Connection, ip=[::ffff:127.0.0.1]
...
The -n
switch tells sed to not output each line of the file it reads (default behaviour).
The last p
after the regular expressions tells it to print lines that match the preceding expression.
The expression '/pattern1/,/pattern2/'
will print everything that is between first pattern and second pattern. In this case it will print every line it finds between the string Feb 23 13:55
and the string Feb 23 14:00
.
Without using any type of JOIN cumulative salary for a person fetch by using follow query:
SELECT * , (
SELECT SUM( salary )
FROM `abc` AS table1
WHERE table1.ID <= `abc`.ID
AND table1.name = `abc`.Name
) AS cum
FROM `abc`
ORDER BY Name
You can use eval
to execute a string:
eval $illcommando
You can check if the element has child nodes element.hasChildNodes()
. Beware in Mozilla this will return true if the is whitespace after the tag so you will need to verify the tag type.
Use regular expression to match your requirement.
String num,num1,num2;
String str = "123-456-789";
String regex ="(\\d+)";
Matcher matcher = Pattern.compile( regex ).matcher( str);
while (matcher.find( ))
{
num = matcher.group();
System.out.print(num);
}
So there is another way you can actually fire it from any language. The best way I think, you can just create a batch file which will call your .dtsx package.
Next you call the batch file from any language. As in windows platform, you can run batch file from anywhere, I think this will be the most generic approach for your purpose. No code dependencies.

You can get the current year using DATEPART
function, from the current date obtained using getUTCDate()
SELECT
'01/01/' + CONVERT(VARCHAR(4), DATEPART(yy, getUTCDate())),
'31/12/' + CONVERT(VARCHAR(4), DATEPART(yy, getUTCDate()))

.Users who try to rename or deleate System files in any protected directory of windows should know that all windows files are protected by DACLS while renaming a file you have to change the owner and replace TrustedInstaller which owns the file and make any user like a user who belongs to administrator group as owner of file then try to rename it after changing the permission, it will work and while you are running windows explorer with kernel privilages you are somewhat limited in terms of Network access for security reasons and it is still a research topic for me to get access back
using date method, we should be able to get the result. ie; date('N/D/l', mktime(0, 0, 0, month, day, year));
For Example
echo date('N', mktime(0, 0, 0, 7, 1, 2017)); // will return 6
echo date('D', mktime(0, 0, 0, 7, 1, 2017)); // will return Sat
echo date('l', mktime(0, 0, 0, 7, 1, 2017)); // will return Saturday
One way to accomplish this is...
$('select').select2().select2('val', $('.select2 option:eq(1)').val());
So basically you first initalize the plugin then specify the default value using the 'val' parameter. The actual value is taken from the specified option, in this case #1. So the selected value from this example would be "bar".
<select class=".select2">
<option id="foo">Some Text</option>
<option id="bar">Other Text</option>
</select>
Hope this is useful to someone else.
for a list
Collections.sort(list, Collections.reverseOrder());
for an array
Arrays.sort(array, Collections.reverseOrder());
All those answers didnt help me, BUT I found another solution.
I had an Entity A containing a List of Entity B. Entity B contained a List of Entity C.
I was trying to update Entity A and B. It worked. But when updating Entity C, I got the mentioned error. In entity B I had an annotation like this:
@OneToMany(mappedBy = "entity_b", cascade = [CascadeType.ALL] , orphanRemoval = true)
var c: List<EntityC>?,
I simply removed orphanRemoval
and the update worked.
An abstract method is a method signature declaration with no body. For instance:
public abstract class Shape {
. . .
public abstract double getArea();
public abstract double getPerimeter();
}
The methods getArea()
and getPerimeter()
are abstract. Because the Shape
class has an abstract method, it must be declared abstract
as well. A class may also be declared abstract
without any abstract methods. When a class is abstract, an instance of it cannot be created; one can only create instances of (concrete) subclasses. A concrete class is a class that is not declared abstract (and therefore has no abstract methods and implements all inherited abstract methods). For instance:
public class Circle extends Shape {
public double radius;
. . .
public double getArea() {
return Math.PI * radius * radius;
}
public double getPerimeter() {
return 2.0 * Math.PI * radius;
}
}
There are many reasons to do this. One would be to write a method that would be the same for all shapes but that depends on shape-specific behavior that is unknown at the Shape
level. For instance, one could write the method:
public abstract class Shape {
. . .
public void printArea(PrintStream out) {
out.println("The area is " + getArea());
}
}
Admittedly, this is a contrived example, but it shows the basic idea: define concrete behavior in terms of unspecified behavior.
Another reason for having an abstract class is so you can partially implement an interface. All methods declared in an interface are inherited as abstract methods by any class that implements the interface. Sometimes you want to provide a partial implementation of an interface in a class and leave the details to subclasses; the partial implementation must be declared abstract.
If you're just looking for a syntactically simple way to assign/return a string or numeric based on a boolean condition, you can use the multiplication operator like this:
"Condition is "+("true"*$condition)+("false"*!$condition)
(12.34*$condition)+(56.78*!$condition)
If you're only ever interested in the result when something is true, you can just omit the false part entirely (or vice versa), e.g. a simple scoring system:
$isTall = $true
$isDark = $false
$isHandsome = $true
$score = (2*$isTall)+(4*$isDark)+(10*$isHandsome)
"Score = $score"
# or
# "Score = $((2*$isTall)+(4*$isDark)+(10*$isHandsome))"
Note that the boolean value should not be the leading term in the multiplication, i.e. $condition*"true" etc. won't work.
It's not actually an Apache related question. Nor even a PHP related one. To understand this error you have to distinguish a path on the virtual server from a path in the filesystem.
require
operator works with files. But a path like this
/common/configs/config_templates.inc.php
only exists on the virtual HTTP server, while there is no such path in the filesystem. The correct filesystem path would be
/home/viapics1/public_html/common/configs/config_templates.inc.php
where
/home/viapics1/public_html
part is called the Document root and it connects the virtual world with the real one. Luckily, web-servers usually have the document root in a configuration variable that they share with PHP. So if you change your code to something like this
require_once $_SERVER['DOCUMENT_ROOT'].'/common/configs/config_templates.inc.php';
it will work from any file placed in any directory!
Update: eventually I wrote an article that explains the difference between relative and absolute paths, in the file system and on the web server, which explains the matter in detail, and contains some practical solutions. Like, such a handy variable doesn't exist when you run your script from a command line. In this case a technique called "a single entry point" is to the rescue. You may refer to the article above for the details as well.
Whenever you try to show a Link
on a page thats outside the BrowserRouter
you will get that error.
This error message is essentially saying that any component that is not a child of our <Router>
cannot contain any React Router related components.
You need to migrate your component hierarchy to how you see it in the first answer above. For anyone else reviewing this post who may need to look at more examples.
Let's say you have a Header.js
component that looks like this:
import React from 'react';
import { Link } from 'react-router-dom';
const Header = () => {
return (
<div className="ui secondary pointing menu">
<Link to="/" className="item">
Streamy
</Link>
<div className="right menu">
<Link to="/" className="item">
All Streams
</Link>
</div>
</div>
);
};
export default Header;
And your App.js
file looks like this:
import React from 'react';
import { BrowserRouter, Route, Link } from 'react-router-dom';
import StreamCreate from './streams/StreamCreate';
import StreamEdit from './streams/StreamEdit';
import StreamDelete from './streams/StreamDelete';
import StreamList from './streams/StreamList';
import StreamShow from './streams/StreamShow';
import Header from './Header';
const App = () => {
return (
<div className="ui container">
<Header />
<BrowserRouter>
<div>
<Route path="/" exact component={StreamList} />
<Route path="/streams/new" exact component={StreamCreate} />
<Route path="/streams/edit" exact component={StreamEdit} />
<Route path="/streams/delete" exact component={StreamDelete} />
<Route path="/streams/show" exact component={StreamShow} />
</div>
</BrowserRouter>
</div>
);
};
export default App;
Notice that the Header.js
component is making use of the Link
tag from react-router-dom
but the componet was placed outside the <BrowserRouter>
, this will lead to the same error as the one experience by the OP. In this case, you can make the correction in one move:
import React from 'react';
import { BrowserRouter, Route } from 'react-router-dom';
import StreamCreate from './streams/StreamCreate';
import StreamEdit from './streams/StreamEdit';
import StreamDelete from './streams/StreamDelete';
import StreamList from './streams/StreamList';
import StreamShow from './streams/StreamShow';
import Header from './Header';
const App = () => {
return (
<div className="ui container">
<BrowserRouter>
<div>
<Header />
<Route path="/" exact component={StreamList} />
<Route path="/streams/new" exact component={StreamCreate} />
<Route path="/streams/edit" exact component={StreamEdit} />
<Route path="/streams/delete" exact component={StreamDelete} />
<Route path="/streams/show" exact component={StreamShow} />
</div>
</BrowserRouter>
</div>
);
};
export default App;
Please review carefully and ensure you have the <Header />
or whatever your component may be inside of not only the <BrowserRouter>
but also inside of the <div>
, otherwise you will also get the error that a Router may only have one child which is referring to the <div>
which is the child of <BrowserRouter>
. Everything else such as Route
and components must go within it in the hierarchy.
So now the <Header />
is a child of the <BrowserRouter>
within the <div>
tags and it can successfully make use of the Link
element.
With me I got an error when run vagrant up

It can solved my problem. Hope this can help for someone who face the same problem.
Here are the various ways to do this so you can compare how it looks and choose what you like. I've ordered them in a way that I think is most "pythonic", and commented the pros and cons that might not be obvious at first glance:
Using collections.defaultdict
:
import collections
dict_x = collections.defaultdict(list)
...
dict_x[key].append(value)
Pros: Probably best performance. Cons: Not available in Python 2.4.x.
Using dict().setdefault()
:
dict_x = {}
...
dict_x.setdefault(key, []).append(value)
Cons: Inefficient creation of unused list()
s.
Using try ... except
:
dict_x = {}
...
try:
values = dict_x[key]
except KeyError:
values = dict_x[key] = []
values.append(value)
Or:
try:
dict_x[key].append(value)
except KeyError:
dict_x[key] = [value]
By changing
compile 'com.google.android.gms:play-services:8.1.0'
to only needed files, the problem can be solved This Issue is generated because of exceeding files in th build.gradle file.
As per your question,
List<Double> frameList = new ArrayList<Double>();
First you have to convert List<Double>
to Double[]
by using
Double[] array = frameList.toArray(new Double[frameList.size()]);
Next you can convert Double[]
to double[]
using
double[] doubleArray = ArrayUtils.toPrimitive(array);
You can directly use it in one line:
double[] array = ArrayUtils.toPrimitive(frameList.toArray(new Double[frameList.size()]));
If you're running Angular 2 through ASP.NET Core 1 in Visual Studio 2015, you might find this solution from Jürgen Gutsch helpful. He describes it in a blog post. It was the best solution for me. Place the C# code provided below in your Startup.cs public void Configure() just before app.UseStaticFiles();
app.Use( async ( context, next ) => {
await next();
if( context.Response.StatusCode == 404 && !Path.HasExtension( context.Request.Path.Value ) ) {
context.Request.Path = "/index.html";
await next();
}
});
I don't have enough points to comment on an answer, but I wanted to say that mikec's answer worked for me except that I had to change it to return !isScrollable like so:
mScroller.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
return !isScrollable;
}
});
you can do this by:
name = 'Bob'
if type(name) == str:
print 'this works'
else:
print 'this does not work'
and it will return 'this works'... but if you change name to int(1) then it will return 'this does not work' because it is now a string... you can also try:
name = int(5)
if type(name) == int:
print 'this works'
else:
print 'this does not work'
and the same thing will happen
there are a couple of ways of using a timer:
1) scheduled timer & using selector
NSTimer *t = [NSTimer scheduledTimerWithTimeInterval: 2.0
target: self
selector:@selector(onTick:)
userInfo: nil repeats:NO];
As a side note, instead of using a timer that doesn't repeat and calls the selector after a specified interval, you could use a simple statement like this:
[self performSelector:@selector(onTick:) withObject:nil afterDelay:2.0];
this will have the same effect as the sample code above; but if you want to call the selector every nth time, you use the timer with repeats:YES;
2) self-scheduled timer
NSDate *d = [NSDate dateWithTimeIntervalSinceNow: 60.0];
NSTimer *t = [[NSTimer alloc] initWithFireDate: d
interval: 1
target: self
selector:@selector(onTick:)
userInfo:nil repeats:YES];
NSRunLoop *runner = [NSRunLoop currentRunLoop];
[runner addTimer:t forMode: NSDefaultRunLoopMode];
[t release];
3) unscheduled timer & using invocation
NSMethodSignature *sgn = [self methodSignatureForSelector:@selector(onTick:)];
NSInvocation *inv = [NSInvocation invocationWithMethodSignature: sgn];
[inv setTarget: self];
[inv setSelector:@selector(onTick:)];
NSTimer *t = [NSTimer timerWithTimeInterval: 1.0
invocation:inv
repeats:YES];
and after that, you start the timer manually whenever you need like this:
NSRunLoop *runner = [NSRunLoop currentRunLoop];
[runner addTimer: t forMode: NSDefaultRunLoopMode];
And as a note, onTick: method looks like this:
-(void)onTick:(NSTimer *)timer {
//do smth
}
With second precision, you can print tv_sec
field of timeval
structure that you get from gettimeofday()
function. For example:
#include <sys/time.h>
#include <stdio.h>
int main()
{
struct timeval tv;
gettimeofday(&tv, NULL);
printf("Seconds since Jan. 1, 1970: %ld\n", tv.tv_sec);
return 0;
}
Example of compiling and running:
$ gcc -Wall -o test ./test.c
$ ./test
Seconds since Jan. 1, 1970: 1343845834
Note, however, that its been a while since epoch and so long int
is used to fit a number of seconds these days.
There are also functions to print human-readable times. See this manual page for details. Here goes an example using ctime()
:
#include <time.h>
#include <stdio.h>
int main()
{
time_t clk = time(NULL);
printf("%s", ctime(&clk));
return 0;
}
Example run & output:
$ gcc -Wall -o test ./test.c
$ ./test
Wed Aug 1 14:43:23 2012
$
For bash, store your command like this:
command="ls | grep -c '^'"
Run your command like this:
echo $command | bash
To make an exact spacing, I use Padding
. An example with two images:
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Expanded(
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Image.asset('images/user1.png'),
),
),
Expanded(
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Image.asset('images/user2.png'),
),
)
],
),
You sure can. Create an HTML page with the form in it that will contain the necessary components from the login.aspx page (i.e. username, etc), and make sure they have the same IDs. For you action, make sure it's a post.
You might have to do some code on the login.aspx page in the Page_Load function to read the form (in the Request.Form object) and call the appropriate functions to log the user in, but other than that, you should have access to the form, and can do what you want with it.
On the container holding image you can use a CSS 3 Flexbox to perfectly center the image inside, both vertically and horizontally.
Let's assume you have <div class="container"> as the image holder:
Then as CSS you have to use:
.container {
display: flex;
align-items: center;
justify-content: center;
height: 100%;
}
And this will make all your content inside this div perfectly centered.
There is a very simple way to implement it by replace. For ECMAScript 6:
'foo'.replace(/^./, str => str.toUpperCase())
Result:
'Foo'
Add this library into build.gradle
android {
useLibrary 'org.apache.http.legacy'
}
You can use the substr
function like this:
echo substr($myStr, 0, 5);
The second argument to substr
is from what position what you want to start and third arguments is for how many characters you want to return.
This is solved 100%:
Import settings/local_setting.py in app/main.py:

I had this error and was explicitly setting the blocksize: aesManaged.BlockSize = 128;
Once I removed that, it worked.
As Lucas says, what you are describing is the intended behaviour for the float property. What confuses many people is that float has been pushed well beyond its original intended usage in order to make up for shortcomings in the CSS layout model.
Have a look at Floatutorial if you'd like to get a better understanding of how this property works.
Stages of an executable generation:
(1) pre-processor -> (2) translator/compiler -> (3) linker
In stage 2 (translator/compiler), declaration statements in our code tell to the compiler that these things we are going to use in future and you can find definition later, meaning is :
translator make sure that : what is what ? means declaration
and (3) stage (linker) needs definition to bind the things
Linker make sure that : where is what ? means definition
It uses commas as separators. So you can either set sep=","
or just use read.csv
:
x <- read.csv(file="http://www.irs.gov/file_source/pub/irs-soi/countyinflow1011.csv")
dim(x)
## [1] 113593 9
The error is caused by spaces in some of the values, and unmatched quotes. There are no spaces in the header, so read.table
thinks that there is one column. Then it thinks it sees multiple columns in some of the rows. For example, the first two lines (header and first row):
State_Code_Dest,County_Code_Dest,State_Code_Origin,County_Code_Origin,State_Abbrv,County_Name,Return_Num,Exmpt_Num,Aggr_AGI
00,000,96,000,US,Total Mig - US & For,6973489,12948316,303495582
And unmatched quotes, for example on line 1336 (row 1335) which will confuse read.table
with the default quote
argument (but not read.csv
):
01,089,24,033,MD,Prince George's County,13,30,1040
Try the packaged pecl version instead (the advantage of the packaged installs is that they're easier to upgrade):
apt-get install php5-dev
pecl install pdo
pecl install pdo_pgsql
or, if you just need a driver for PHP, but that it doesn't have to be the PDO one:
apt-get install php5-pgsql
Otherwise, that message most likely means you need to install a more recent libpq package. You can check which version you have by running:
dpkg -s libpq-dev
curl's --data
will by default send Content-Type: application/x-www-form-urlencoded
in the request header. However, when using Postman's raw
body mode, Postman sends Content-Type: text/plain
in the request header.
So to achieve the same thing as Postman, specify -H "Content-Type: text/plain"
for curl:
curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/
Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network

Here's a sample class:
public class Increment
{
public static void main(String [] args)
{
for (int i = 0; i < args.length; ++i)
{
System.out.println(args[i]);
}
}
}
If I disassemble this class using javap.exe I get this:
Compiled from "Increment.java"
public class Increment extends java.lang.Object{
public Increment();
Code:
0: aload_0
1: invokespecial #1; //Method java/lang/Object."<init>":()V
4: return
public static void main(java.lang.String[]);
Code:
0: iconst_0
1: istore_1
2: iload_1
3: aload_0
4: arraylength
5: if_icmpge 23
8: getstatic #2; //Field java/lang/System.out:Ljava/io/PrintStream;
11: aload_0
12: iload_1
13: aaload
14: invokevirtual #3; //Method java/io/PrintStream.println:(Ljava/lang/String;)V
17: iinc 1, 1
20: goto 2
23: return
}
If I change the loop so it uses i++ and disassemble again I get this:
Compiled from "Increment.java"
public class Increment extends java.lang.Object{
public Increment();
Code:
0: aload_0
1: invokespecial #1; //Method java/lang/Object."<init>":()V
4: return
public static void main(java.lang.String[]);
Code:
0: iconst_0
1: istore_1
2: iload_1
3: aload_0
4: arraylength
5: if_icmpge 23
8: getstatic #2; //Field java/lang/System.out:Ljava/io/PrintStream;
11: aload_0
12: iload_1
13: aaload
14: invokevirtual #3; //Method java/io/PrintStream.println:(Ljava/lang/String;)V
17: iinc 1, 1
20: goto 2
23: return
}
When I compare the two, TextPad tells me that the two are identical.
What this says is that from the point of view of the generated byte code there's no difference in a loop. In other contexts there is a difference between ++i and i++, but not for loops.
Adding on to the one mentioned by @abarnert
a better one is to catch the exception
import subprocess
try:
py2output = subprocess.check_output(['python', 'py2.py', '-i', 'test.txt'],stderr= subprocess.STDOUT)
#print('py2 said:', py2output)
print "here"
except subprocess.CalledProcessError as e:
print "Calledprocerr"
this stderr= subprocess.STDOUT is for making sure you dont get the filenotfound error in stderr- which cant be usually caught in filenotfoundexception, else you would end up getting
python: can't open file 'py2.py': [Errno 2] No such file or directory
Infact a better solution to this might be to check, whether the file/scripts exist and then to run the file/script
So, your input is 'dan|warrior|54' and you want "warrior". You do this like so:
>>> dan = 'dan|warrior|54'
>>> dan.split('|')[1]
"warrior"
Keep 2 stacks, let's call them inbox
and outbox
.
Enqueue:
inbox
Dequeue:
If outbox
is empty, refill it by popping each element from inbox
and pushing it onto outbox
Pop and return the top element from outbox
Using this method, each element will be in each stack exactly once - meaning each element will be pushed twice and popped twice, giving amortized constant time operations.
Here's an implementation in Java:
public class Queue<E>
{
private Stack<E> inbox = new Stack<E>();
private Stack<E> outbox = new Stack<E>();
public void queue(E item) {
inbox.push(item);
}
public E dequeue() {
if (outbox.isEmpty()) {
while (!inbox.isEmpty()) {
outbox.push(inbox.pop());
}
}
return outbox.pop();
}
}

I assume that the main idea is to find if number is negative and display it in correct format.
For those who use PHP5.3 might be interested in using Number Formatter Class - http://php.net/manual/en/class.numberformatter.php. This function, as well as range of other useful things, can format your number.
$profitLoss = 25000 - 55000;
$a= new \NumberFormatter("en-UK", \NumberFormatter::CURRENCY);
$a->formatCurrency($profitLoss, 'EUR');
// would display (€30,000.00)
Here also a reference to why brackets are used for negative numbers: http://www.open.edu/openlearn/money-management/introduction-bookkeeping-and-accounting/content-section-1.7
Thankfully, with C++11 there is also the more pleasing approach of using raw string literals.
printf("She said \"time flies like an arrow, but fruit flies like a banana\".");
Becomes:
printf(R"(She said "time flies like an arrow, but fruit flies like a banana".)");
With respect to the addition of brackets after the opening quote, and before the closing quote, note that they can be almost any combination of up to 16 characters, helping avoid the situation where the combination is present in the string itself. Specifically:
any member of the basic source character set except: space, the left parenthesis (, the right parenthesis ), the backslash , and the control characters representing horizontal tab, vertical tab, form feed, and newline" (N3936 §2.14.5 [lex.string] grammar) and "at most 16 characters" (§2.14.5/2)
How much clearer it makes this short strings might be debatable, but when used on longer formatted strings like HTML or JSON, it's unquestionably far clearer.
Implementation is up to compiler developers.
If your question is "what will happen with such declaration" - compiler will set first array element to the value you've provided (0) and all others will be set to zero because it is a default value for omitted array elements.
If you are using Angular 6.1 or later, the most convenient way is to use KeyValuePipe
@Component({
selector: 'keyvalue-pipe',
template: `<span>
<p>Object</p>
<div *ngFor="let item of object | keyvalue">
{{item.key}}:{{item.value}}
</div>
<p>Map</p>
<div *ngFor="let item of map | keyvalue">
{{item.key}}:{{item.value}}
</div>
</span>`
})
export class KeyValuePipeComponent {
object: Record<number, string> = {2: 'foo', 1: 'bar'};
map = new Map([[2, 'foo'], [1, 'bar']]);
}
When you use android:background, you are replacing much of the styling and look and feel of a button with a blank color.
Update: As of the version 23.0.0 release of AppCompat, there is a new Widget.AppCompat.Button.A colored style which uses your theme's colorButtonNormal for the disabled color and colorAccent for the enabled color.
This allows you apply it to your button directly via
<Button
...
style="@style/Widget.AppCompat.Button.Colored" />
You can use a drawable in your v21 directory for your background such as:
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?attr/colorControlHighlight">
<item android:drawable="?attr/colorPrimary"/>
</ripple>
This will ensure your background color is ?attr/colorPrimary and has the default ripple animation using the default ?attr/colorControlHighlight (which you can also set in your theme if you'd like).
Note: you'll have to create a custom selector for less than v21:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/primaryPressed" android:state_pressed="true"/>
<item android:drawable="@color/primaryFocused" android:state_focused="true"/>
<item android:drawable="@color/primary"/>
</selector>
It is possible to use patterns in a .gitignore
file. See the gitignore man page. The pattern */target/*
should ignore any directory named target and anything under it. Or you may try */target/**
to ignore everything under target.
If you want to change the status bar color programmatically (and provided the device has Android 5.0). This is a simple way to change statusBarColor from any Activity and very easy methods when differents fragments have different status bar color.
/**
* @param colorId id of color
* @param isStatusBarFontDark Light or Dark color
*/
fun updateStatusBarColor(@ColorRes colorId: Int, isStatusBarFontDark: Boolean = true) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
val window = window
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
window.statusBarColor = ContextCompat.getColor(this, colorId)
setSystemBarTheme(isStatusBarFontDark)
}
}
/** Changes the System Bar Theme. */
@RequiresApi(api = Build.VERSION_CODES.M)
private fun setSystemBarTheme(isStatusBarFontDark: Boolean) {
// Fetch the current flags.
val lFlags = window.decorView.systemUiVisibility
// Update the SystemUiVisibility depending on whether we want a Light or Dark theme.
window.decorView.systemUiVisibility = if (isStatusBarFontDark) lFlags and View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR.inv() else lFlags or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
}
as Itsproinc said, the REN
command works!
but if your file path/name has spaces, use quotes " "
example:
ren C:\Users\&username%\Desktop\my file.txt not my file.txt
add " "
ren "C:\Users\&username%\Desktop\my file.txt" "not my file.txt"
hope it helps
To be able to create a relation, the table Storage Engine must be InnoDB. You can edit in Operations tab.
Then, you need to be sure that the id column in your main table has been indexed. It should appear at Index section in Structure tab.
Finally, you could see the option Relations View in Structure tab. When edditing, you will be able to select the parent column in foreign table to create the relation.
See attachments. I hope this could be useful for anyone.
The values you provided are UTF-8 values. When set, the array of:
declare -a ARR=(0xA7 0x9B 0x46 0x8D 0x1E 0x52 0xA7 0x9B 0x7B 0x31 0xD2)
Will be parsed to print the plaintext characters of each value.
for ((n=0; n < ${#ARR[*]}; n++)); do echo -e "\u${ARR[$n]//0x/}"; done
And the output will yield a few printable characters and some non-printable characters as shown here:
For converting hex values to plaintext using the echo
command:
echo -e "\x<hex value here>"
And for converting UTF-8 values to plaintext using the echo
command:
echo -e "\u<UTF-8 value here>"
And then for converting octal to plaintext using the echo
command:
echo -e "\0<octal value here>"
When you have encoding values you aren't familiar with, take the time to check out the ranges in the common encoding schemes to determine what encoding a value belongs to. Then conversion from there is a snap.
A copy-paste modern version ( using fetch and arrow function ) :
//Option with catch
fetch( textURL )
.then(async r=> console.log(await r.text()))
.catch(e=>console.error('Boo...' + e));
//No fear...
(async () =>
console.log(
(await (await fetch( jsonURL )).json())
)
)();
A copy-paste classic version:
let request = new XMLHttpRequest();
request.onreadystatechange = function () {
if (this.readyState === 4) {
if (this.status === 200) {
document.body.className = 'ok';
console.log(this.responseText);
} else if (this.response == null && this.status === 0) {
document.body.className = 'error offline';
console.log("The computer appears to be offline.");
} else {
document.body.className = 'error';
}
}
};
request.open("GET", url, true);
request.send(null);
There is no such thing as an "epoch" in a specific timezone. The epoch is well-defined as a specific moment in time, so if you change the timezone, the time itself changes as well. Specifically, this time is Jan 1 1970 00:00:00 UTC
. So time.time()
returns the number of seconds since the epoch.
UPDATE git 1.8.3 introduced a more efficient way to get a rough size:
git count-objects -vH
(see answer by @VonC)
For different ideas of "complete size" you could use:
git bundle create tmp.bundle --all
du -sh tmp.bundle
Close (but not exact:)
git gc
du -sh .git/
With the latter, you would also be counting:
It would be more beneficial for us if we could see the actual project structure, as the classes alone do not say that much.
Assuming that both .cs files are in the same project (if they are in different projects inside the same solution, you'd have to add a reference to the project containing Class2.cs), you can click on the Class2
occurrence in your code that is underlined in red and press CTRL + . (period) or click on the blue bar that should be there. The first option appearing will then add the appropriate using
statement automatically. If there is no such menu, it may indicate that there is something wrong with the project structure or a reference missing.
You could try making Class2
public
, but it sounds like this can't be a problem here, since by default what you did is internal class Class2
and thus Class2
should be accessible if both are living in the same project/assembly. If you are referencing a different assembly or project wherein Class2
is contained, you have to make it public
in order to access it, as internal
classes can't be accessed from outside their assembly.
As for renaming: You can click Program.cs
in the Solution Explorer and press F2 to rename it. It will then open up a dialog window asking you if the class Program
itself and all references thereof should be renamed as well, which is usually what you want. Or you could just rename the class Program
in the declaration and again open up the menu with the small blue bar (or, again, CTRL+.) and do the same, but it won't automatically rename the actual file accordingly.
Edit after your question edit: I have never used this option you used, but from quick checking I think that it's really not inside the same project then. Do the following when adding new classes to a project: In the Solution Explorer, right click the project you created and select [Add] -> [Class] or [Add] -> [New Item...] and then select 'Class'. This will automatically make the new class part of the project and thus the assembly (the assembly is basically the 'end product' after building the project). For me, there is also the shortcut Alt+Shift+C working to create a new class.
For some reason, the above answer did not work for me; I did not return to the command prompt after running it as I expected with the trailing &. Instead, I simply tried with
nohup some_command > nohup2.out&
and it works just as I want it to. Leaving this here in case someone else is in the same situation. Running Bash 4.3.8 for reference.
To rename a table in SQL Server, use the sp_rename
command:
exec sp_rename 'schema.old_table_name', 'new_table_name'
You can't change img
tag's src
attribute using CSS
. Possible using Javascript onmouseover()
event handler.

Javascript:
function hover() {
document.getElementById("my-img").src = "http://dummyimage.com/100x100/eb00eb/fff";
}
For my case, I was trying to execute procedure code in MySQL, and due to some issue with server in which Server can't figure out where to end the statement I was getting Error Code 1064. So I wrapped the procedure with custom DELIMITER and it worked fine.
For example, Before it was:
DROP PROCEDURE IF EXISTS getStats;
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
/*Procedure Code Here*/
END;
After putting DELIMITER it was like this:
DROP PROCEDURE IF EXISTS getStats;
DELIMITER $$
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
/*Procedure Code Here*/
END;
$$
DELIMITER ;
As m.edmondson mentioned, "The remote host closed the connection." occurs when a user or browser cancels something, or the network connection drops etc. It doesn't necessarily have to be a file download however, just any request for any resource that results in a response to the client. Basically the error means that the response could not be sent because the server can no longer talk to the client(browser).
There are a number of steps that you can take in order to stop it happening. If you are manually sending something in the response with a Response.Write, Response.Flush, returning data from a web servivce/page method or something similar, then you should consider checking Response.IsClientConnected before sending the response. Also, if the response is likely to take a long time or a lot of server-side processing is required, you should check this periodically until the response.end if called. See the following for details on this property:
http://msdn.microsoft.com/en-us/library/system.web.httpresponse.isclientconnected.aspx
Alternatively, which I believe is most likely in your case, the error is being caused by something inside the framework. The following link may by of use:
The following stack-overflow post might also be of interest:
"The remote host closed the connection" in Response.OutputStream.Write
This can not be done purely with css. This is a behaviour, which affects the styling of the page.
With jquery you can quickly implement the behavior from your question:
$(function() {
$('#a').hover(function() {
$('#b').css('background-color', 'yellow');
}, function() {
// on mouseout, reset the background colour
$('#b').css('background-color', '');
});
});
You are overwriting your object file runexp.o
by running this command :
gcc -o runexp.o scd.o data_proc.o -lm -fopenmp
In fact, the -o
is for the output file.
You need to run :
gcc -o runexp.out runexp.o scd.o data_proc.o -lm -fopenmp
runexp.out will be you binary file.
If you need simplify code then live is better in the most cases. If you need to get the best performance then delegate will always better than live. bind (click) vs delegate isn't so simple question (if you have a lot of similar items then delegate will be better).
just call the finish() in the method you would like to end the activity in, for example when you use the onCreate() method, in the end of the method, just add finish() and you will see the activity ends as soon as it is created!
The manual for GNU Make gives a clear definition for all
in its list of standard targets.
If the author of the Makefile is following that convention then the target all
should:
make
should do the same as make all
.To achieve 1 all
is typically defined as a .PHONY
target that depends on the executable(s) that form the entire program:
.PHONY : all
all : executable
To achieve 2 all
should either be the first target defined in the make file or be assigned as the default goal:
.DEFAULT_GOAL := all
>>> a = numpy.full((2,4), True, dtype=bool)
>>> a[1][3]
True
>>> a
array([[ True, True, True, True],
[ True, True, True, True]], dtype=bool)
numpy.full(Size, Scalar Value, Type). There is other arguments as well that can be passed, for documentation on that, check https://docs.scipy.org/doc/numpy/reference/generated/numpy.full.html
FYI here is a function to convert a permission string with 9 characters (e.g. 'rwsr-x-wt') to a mask that can be used with os.chmod()
.
def perm2mask(p):
assert len(p) == 9, 'Bad permission length'
assert all(p[k] in 'rw-' for k in [0,1,3,4,6,7]), 'Bad permission format (read-write)'
assert all(p[k] in 'xs-' for k in [2,5]), 'Bad permission format (execute)'
assert p[8] in 'xt-', 'Bad permission format (execute other)'
m = 0
if p[0] == 'r': m |= stat.S_IRUSR
if p[1] == 'w': m |= stat.S_IWUSR
if p[2] == 'x': m |= stat.S_IXUSR
if p[2] == 's': m |= stat.S_IXUSR | stat.S_ISUID
if p[3] == 'r': m |= stat.S_IRGRP
if p[4] == 'w': m |= stat.S_IWGRP
if p[5] == 'x': m |= stat.S_IXGRP
if p[5] == 's': m |= stat.S_IXGRP | stat.S_ISGID
if p[6] == 'r': m |= stat.S_IROTH
if p[7] == 'w': m |= stat.S_IWOTH
if p[8] == 'x': m |= stat.S_IXOTH
if p[8] == 't': m |= stat.S_IXOTH | stat.S_ISVTX
return m
Note that setting SUID/SGID/SVTX bits will automatically set the corresponding execute bit. Without this, the resulting permission would be invalid (ST
characters).
For an instance
Character.Gorgon gor = new Character.Gorgon();
Then do
gor instanceof Monster
For a Class instance do
Class<?> clazz = Character.Gorgon.class;
Monster.class.isAssignableFrom(clazz);

You can't do this using sharer.php, but you can do something similar using the Dialog API. http://developers.facebook.com/docs/reference/dialogs/

The catch is you must create a dummy Facebook application just to have an app_id
. Note that your Facebook application doesn't have to do ANYTHING at all. Just be sure that it is properly configured, and you should be all set.
The following solution seems to be a much shorter version for that:
<div id="imageDiv"></div>
In Javascript:
document.getElementById('imageDiv').innerHTML = '<img width="100" height="100" src="images/hydrangeas.jpg">';
if it is window7(like mine), without administrative rights cannot write a file at C: drive
just give another folder in log4j.properties file
Set the name of the file
log4j.appender.FILE.File=C:\server\log.out you can see with notepad++
Depending on how you are running the command, you can put /k
after cmd
to keep the window open.
cmd /k my_script.bat
Simply adding cmd /k
to the end of your batch file will work too. Credit to Luigi D'Amico who posted about this in the comments below.
You can wrap it in your own function:
function isNullAndUndef(variable) {
return (variable !== null && variable !== undefined);
}
I am getting the error (...) javax.naming.NameNotFoundException: greetJndi not bound
This means that nothing is bound to the jndi name greetJndi
, very likely because of a deployment problem given the incredibly low quality of this tutorial (check the server logs). I'll come back on this.
Is there any specific directory structure to deploy in JBoss?
The internal structure of the ejb-jar

in the ejb-jar.xml
and jboss.xml

That tutorial needs significant improvement; I'd advise from staying away from roseindia.net.
This came from standford's sna free tutorial and it states that ...
# Reachability can only be computed on one vertex at a time. To
# get graph-wide statistics, change the value of "vertex"
# manually or write a for loop. (Remember that, unlike R objects,
# igraph objects are numbered from 0.)
ok, so when ever using igraph, the first roll/column is 0 other than 1, but matrix starts at 1, thus for any calculation under igraph, you would need x-1, shown at
this_node_reach <- subcomponent(g, (i - 1), mode = m)
but for the alter calculation, there is a typo here
alter = this_node_reach[j] + 1
delete +1 and it will work alright
You have several options, I'll start from the easiest:
1- Change the input buttons to links, you can style them with css so they look like buttons:
<a href="CreateCourse.jsp">Creazione Nuovo Corso</a>
instead of
<input type="button" value="Creazione Nuovo Corso" name="CreateCourse" />
2- Use javascript to change the action of the form depending on the button you click:
<input type="button" value="Creazione Nuovo Corso" name="CreateCourse"
onclick="document.forms[0].action = 'CreateCourse.jsp'; return true;" />
3- Use a servlet or JSP to handle the request and redirect or forward to the appropriate JSP page.
Try to add title
and alt
properties to your image.... Gmail and some others blocks images without some attributes.. and it is also a logic to include your email to be read as spam.
The problem with @grenoult's CSS solution (which does work, mostly), is that it is fully responsive and on mobile when the keyboard pops up (i.e. when they click in an input in the modal dialog) the screen size changes and the modal dialog's size changes and it can hide the input they just clicked on so they can't see what they are typing.
The better solution for me was to use jquery as follows:
$(".modal-body").css({ "max-height" : $(window).height() - 212, "overflow-y" : "auto" });
It isn't responsive to changing the window size, but that doesn't happen that often anyway.
Use a regular expression, e.g.
[RegularExpression("([1-9][0-9]*)", ErrorMessage = "Count must be a natural number")]
public int Count { get; set; }
There are two ways:
The best way is to remove the <p>
altogether. It is acting according to specification when it adds space.
Alternately, use CSS to style the <p>
. Something like:
ul li p {
padding: 0;
margin: 0;
display: inline;
}
None of these worked for me using 4.1 video.js CDN. This code kills the video playing in a modal when the (.closemodal
) is clicked. I had 3 videos. Someone else can refactor.
var myPlayer = videojs("my_video_1");
var myPlayer2 = videojs("my_video_2");
var myPlayer3 = videojs("my_video_3");
$(".closemodal").click(function(){
myPlayer.pause();
myPlayer2.pause();
myPlayer3.pause();
});
});
as per their Api docs.
When you extract a single row from a data frame you get a one-row data frame. Convert it to a numeric vector:
as.numeric(df[1,])
As @Roland suggests, unlist(df[1,])
will convert the one-row data frame to a numeric vector without dropping the names. Therefore unname(unlist(df[1,]))
is another, slightly more explicit way to get to the same result.
As @Josh comments below, if you have a not-completely-numeric (alphabetic, factor, mixed ...) data frame, you need as.character(df[1,])
instead.
C++11 standard on jumping over some initializations
JohannesD gave an explanation, now for the standards.
The C++11 N3337 standard draft 6.7 "Declaration statement" says:
3 It is possible to transfer into a block, but not in a way that bypasses declarations with initialization. A program that jumps (87) from a point where a variable with automatic storage duration is not in scope to a point where it is in scope is ill-formed unless the variable has scalar type, class type with a trivial default constructor and a trivial destructor, a cv-qualified version of one of these types, or an array of one of the preceding types and is declared without an initializer (8.5).
87) The transfer from the condition of a switch statement to a case label is considered a jump in this respect.
[ Example:
void f() { // ... goto lx; // ill-formed: jump into scope of a // ... ly: X a = 1; // ... lx: goto ly; // OK, jump implies destructor // call for a followed by construction // again immediately following label ly }
— end example ]
As of GCC 5.2, the error message now says:
crosses initialization of
C
C allows it: c99 goto past initialization
The C99 N1256 standard draft Annex I "Common warnings" says:
2 A block with initialization of an object that has automatic storage duration is jumped into
Initially used only ViewDidLoad with tableView. On testing with loss of Wifi, by setting device to airplane mode, realized that the table did not refresh with return of Wifi. In fact, there appears to be no way to refresh tableView on the device even by hitting the home button with background mode set to YES in -Info.plist.
My solution:
-(void) viewWillAppear: (BOOL) animated { [self.tableView reloadData];}
I would go with Option 3 but multiple NON NULLABLE bit columns instead of one. IsMale (1=Yes / 0=No) IsFemale (1=Yes / 0=No)
if requried: IsUnknownGender (1=Yes / 0=No) and so on...
This makes for easy reading of the definitions, easy extensibility, easy programmability, no possibility of using values outside the domain and no requirement of a second lookup table+FK or CHECK constraints to lock down the values.
EDIT: Correction, you do need at least one constraint to ensure the set flags are valid.
You can also use ls
with grep
or egrep
and put it in your profile as an alias:
ls -l | egrep -v '^d'
ls -l | grep -v '^d'
if you use window.open(url, '_blank')
, it will be blocked(popup blocker) on Chrome,Firefox etc
try this,
$('#myButton').click(function () {
var redirectWindow = window.open('http://google.com', '_blank');
redirectWindow.location;
});

Your docker host exposes an adapter to all the containers. Assuming you are on recent ubuntu, you can run
ip addr
This will give you a list of network adapters, one of which will look something like
3: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
link/ether 22:23:6b:28:6b:e0 brd ff:ff:ff:ff:ff:ff
inet 172.17.42.1/16 scope global docker0
inet6 fe80::a402:65ff:fe86:bba6/64 scope link
valid_lft forever preferred_lft forever
You will need to tell rabbit/mongo to bind to that IP (172.17.42.1). After that, you should be able to open connections to 172.17.42.1 from within your containers.
Try using the following:
String str = "This is a simple sentence";
String[] strgs = str.split(" ");
That will create a substring at each index of the array of strings using the space as a split point.
On Windows 10, I have docker installed. I am running Jnekins on a container and I encountered the same error message. Here is a step by step guide to resolve this issue:
Step 1: Open gitbash and run docker run -p 8080:8080 -p 50000:50000 jenkins.
Step 2: Open a new terminal.
Step 3: Do "docker ps" to get list of the running container. Copy the container id.
Step 4: Now if you do "docker exec -it {container id} sh" or "docker exec -it {container id} bash" you will get an error message similar to " the input device is not a TTY. If you are using mintty, try prefixing the command with 'winpty'"
Step 5: Run command " $winpty docker exec -it {container id} sh"
vola !! You are now inside the terminal.
Should you ever crave deeper understanding, I heartily recommend Patterson and Hennessy as an intro and Hennessy and Patterson as an intermediate to advanced text. They're pricey, but truly non-pareil; I just wish either or both were available when I got my Masters' degree and entered the workforce designing chips, systems, and parts of system software for them (but, alas!, that was WAY too long ago;-). Stack pointers are so crucial (and the distinction between a microprocessor and any other kind of CPU so utterly meaningful in this context... or, for that matter, in ANY other context, in the last few decades...!-) that I doubt anything but a couple of thorough from-the-ground-up refreshers can help!-)
Generate a random number (which is always between 0-1) and multiply by 1000000
Math.round(Math.random()*1000000);
I reckon your aspx page doesn't return a JSON object. Your page should do something like this (page_load)
var jSon = new JavaScriptSerializer();
var OutPut = jSon.Serialize(<your object>);
Response.Write(OutPut);
Also, try to change your AjaxFailed:
function AjaxFailed (XMLHttpRequest, textStatus) {
}
textStatus
should give you the type of error you're getting.
First, let's make some test data:
create table client (client_id integer not null primary key auto_increment,
name varchar(64));
create table portfolio (portfolio_id integer not null primary key auto_increment,
client_id integer references client.id,
cash decimal(10,2),
stocks decimal(10,2));
insert into client (name) values ('John Doe'), ('Jane Doe');
insert into portfolio (client_id, cash, stocks) values (1, 11.11, 22.22),
(1, 10.11, 23.22),
(2, 30.30, 40.40),
(2, 40.40, 50.50);
If you didn't need the portfolio ID, it would be easy:
select client_id, name, max(cash + stocks)
from client join portfolio using (client_id)
group by client_id
+-----------+----------+--------------------+
| client_id | name | max(cash + stocks) |
+-----------+----------+--------------------+
| 1 | John Doe | 33.33 |
| 2 | Jane Doe | 90.90 |
+-----------+----------+--------------------+
Since you need the portfolio ID, things get more complicated. Let's do it in steps. First, we'll write a subquery that returns the maximal portfolio value for each client:
select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id
+-----------+----------+
| client_id | maxtotal |
+-----------+----------+
| 1 | 33.33 |
| 2 | 90.90 |
+-----------+----------+
Then we'll query the portfolio table, but use a join to the previous subquery in order to keep only those portfolios the total value of which is the maximal for the client:
select portfolio_id, cash + stocks from portfolio
join (select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
+--------------+---------------+
| portfolio_id | cash + stocks |
+--------------+---------------+
| 5 | 33.33 |
| 6 | 33.33 |
| 8 | 90.90 |
+--------------+---------------+
Finally, we can join to the client table (as you did) in order to include the name of each client:
select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
+-----------+----------+--------------+---------------+
| client_id | name | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
| 1 | John Doe | 5 | 33.33 |
| 1 | John Doe | 6 | 33.33 |
| 2 | Jane Doe | 8 | 90.90 |
+-----------+----------+--------------+---------------+
Note that this returns two rows for John Doe because he has two portfolios with the exact same total value. To avoid this and pick an arbitrary top portfolio, tag on a GROUP BY clause:
select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
group by client_id, cash + stocks
+-----------+----------+--------------+---------------+
| client_id | name | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
| 1 | John Doe | 5 | 33.33 |
| 2 | Jane Doe | 8 | 90.90 |
+-----------+----------+--------------+---------------+
I would suggest to check the ASCII values to extract numbers from a String Suppose you have an input String as myname12345 and if you want to just extract the numbers 12345 you can do so by first converting the String to Character Array then use the following pseudocode
for(int i=0; i < CharacterArray.length; i++)
{
if( a[i] >=48 && a[i] <= 58)
System.out.print(a[i]);
}
once the numbers are extracted append them to an array
Hope this helps
The default generator for Windows seems to be set to NMAKE. Try to use:
cmake -G "MinGW Makefiles"
Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.
Sometimes rails generate migration add_email_to_users email:string
produces a migration like this
class AddEmailToUsers < ActiveRecord::Migration[5.0]
def change
end
end
In that case you have to manually an add_column
to change
:
class AddEmailToUsers < ActiveRecord::Migration[5.0]
def change
add_column :users, :email, :string
end
end
And then run rake db:migrate
Here's my code for 2D list in python which would read no. of rows from the input :
empty = []
row = int(input())
for i in range(row):
temp = list(map(int, input().split()))
empty.append(temp)
for i in empty:
for j in i:
print(j, end=' ')
print('')
substringsArray.every(substring=>yourBigString.indexOf(substring) === -1)
For full support ;)
I may be late to this one, but would help with the answer:
echo "COL_NAME1|COL_NAME2|COL_NAME3|COL_NAME4" > SAMPLE_Data.csv hive -e ' select distinct concat(COL_1, "|", COL_2, "|", COL_3, "|", COL_4) from table_Name where clause if required;' >> SAMPLE_Data.csv
A few practical facts that might be useful to decide which event to handle (run the script below and focus on the input box):
$('input').on('keyup keydown keypress',e=>console.log(e.type, e.keyCode, e.which, e.key))

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<input/>

Pressing:
non inserting/typing keys (e.g. Shift, Ctrl) will not trigger a keypress
. Press Ctrl and release it:
keydown 17 17 Control
keyup 17 17 Control
keys from keyboards that apply characters transformations to other characters may lead to Dead and duplicate "keys" (e.g. ~, ´) on keydown
. Press ´ and release it in order to display a double ´´
:
keydown 192 192 Dead
keydown 192 192 ´´
keypress 180 180 ´
keypress 180 180 ´
keyup 192 192 Dead
Additionally, non typing inputs (e.g. ranged <input type="range">
) will still trigger all keyup, keydown and keypress events according to the pressed keys.
ANSI C only specifies second precision time functions. However, if you are running in a POSIX environment you can use the gettimeofday() function that provides microseconds resolution of time passed since the UNIX Epoch.
As a side note, I wouldn't recommend using clock() since it is badly implemented on many(if not all?) systems and not accurate, besides the fact that it only refers to how long your program has spent on the CPU and not the total lifetime of the program, which according to your question is what I assume you would like to measure.
I could be able to update the environment variable by using the following
string EnvPath = System.Environment.GetEnvironmentVariable("PATH", EnvironmentVariableTarget.Machine) ?? string.Empty;
if (!string.IsNullOrEmpty(EnvPath) && !EnvPath .EndsWith(";"))
EnvPath = EnvPath + ';';
EnvPath = EnvPath + @"C:\Test";
Environment.SetEnvironmentVariable("PATH", EnvPath , EnvironmentVariableTarget.Machine);
If you place the dollar sign before the letter, you will affect only the column, not the row. If you want to have it affect only a row, place the dollar before the number.
You may want to use =isblank() rather than =""
I'm also confused by your comment "no values throughout spreadsheet - just text" - text is a value.
One more hint - excel has a habit of rewriting rules - I don't know how many rules I've written only to discover that excel has changed the values in the "apply to" or formula entry fields.
If you could post an example, I'll revise the answer. Conditional formatting is very finicky.
Not sure if your teacher allows you to use filters but...
filter(lambda x: x.isalpha(), "a1a2a3s3d4f5fg6h")
returns-
'aaasdffgh'
Much more efficient than looping...
Example:
for i in range(10):
a.replace(str(i),'')
Works for me:
List<Item> list = Task.Run(() => manager.GetList()).Result;
in this way it is not necessary to mark the method with async in the call.
The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).
Typical symptoms:
[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100
[root@host /]# netstat -plant | grep 25
tcp 0 0 :::25 :::* LISTEN 1082/exim
If this happens, make sure that you don't have two entries for localhost
in /etc/hosts
with different IP addresses, like this (bad) example:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
To avoid confusion, make sure you only have one entry for localhost
, preferably an IPv4 address, like this:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4.localdomain4 localhost4
::1 localhost6 localhost6.localdomain6
To show only running containers use the given command:
docker ps
To show all containers use the given command:
docker ps -a
To show the latest created container (includes all states) use the given command:
docker ps -l
To show n last created containers (includes all states) use the given command:
docker ps -n=-1
To display total file sizes use the given command:
docker ps -s
The content presented above is from docker.com.
In the new version of Docker, commands are updated, and some management commands are added:
docker container ls
It is used to list all the running containers.
docker container ls -a
And then, if you want to clean them all,
docker rm $(docker ps -aq)
It is used to list all the containers created irrespective of its state.
And to stop all the Docker containers (force)
docker rm -f $(docker ps -a -q)
Here the container is the management command.
Had the same issue , I finally got it working after some trying. Here are the 8 html tags that I used on my web page to get the preview working :
In <head>
tag:
<meta property="og:title" content="ABC Blabla 2020 Friday" />
<meta property="og:url" content="https://bla123.neocities.org/mp/friday.html" />
<meta property="og:description" content="Photo Album">
<meta property="og:image" itemprop="image" content="https://bla123.neocities.org/mp/images/thumbs/IMG_327.JPG"/>
<meta property="og:type" content="article" />
<meta property="og:locale" content="en_GB" />
In <body>
tag:
<link itemprop="thumbnailUrl" href="https://bla123.neocities.org/mp/images/thumbs/IMG_327.JPG">
<span itemprop="thumbnail" itemscope itemtype="http://schema.org/ImageObject">
<link itemprop="url" href="https://bla123.neocities.org/mp/images/thumbs/IMG_327.JPG">
</span>
These 8 tags ( 6 in head , 2 in body) worked perfectly.
Tips:
1.Use the exact image location URL instead of directory format i.e. don't use images/OG_thumb.jpg
2.Case sensitive file extension: If the image extension name on your hosting provider is ".JPG" then do not use ".jpg" or ".jpeg' . I observed that based on hosting provider and browser combination error may or may not occur, so to be safe its easier to just match the case of file extension.
3.After doing above steps if the thumbnail preview is still not showing up in WhatsApp message then:
a. Force stop the mobile app ( I tried in Android) and try again
b.Use online tool to preview the OG tag eg I used : https://searchenginereports.net/open-graph-checker
c. In mobile browser paste direct link to the OG thumb and refresh the browser 4-5 times . eg https://bla123neocities.org/nmp/images/thumbs/IMG_327.JPG
Well, it seems that the Content-Disposition header was originally created for e-mail, not the web. (Link to relevant RFC.)
I'm guessing that web browsers may respond to
Response.AppendHeader("content-disposition", "inline; filename=" + fileName);
when saving, but I'm not sure.
Today, I had the same problem. My eclipse refused to start. When I double clicked on Eclipse icon I was able to see splashscreen for a second and then nothing happen. Tried most of the solutions here: removed lock file, renamed workspace, tried to start Eclipse with different clean parameters. I even put a new copy of Eclispe and tried to start with a new workspace. Nothing!
My logs were showing bunch of errors from yesterday when my workstation was rebooted at 17:45.
!ENTRY org.eclipse.ui.workbench 4 2 2014-12-17 17:45:12.178
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".
!STACK 0
java.lang.NullPointerException
In the end this very simple change (look below) saved my Eclipse together with my workspace!
SOLUTION:
I edited eclipse.ini
and added following line:
-vm
C:\Program Files\Java\jdk1.6.0_26\bin\javaw.exe
Eclipse has started again with all my projects inside! I hope this can help.
I usually don't like to guess, but I'm going to on this one...
If you remember Microsoft's .NET marketing hype back in the day (2001?), it was hard to tell what .NET even was. Was it a server? a programming platform? a language? something new entirely? Given the ads, it was ambiguously anything you wanted it to be - it just solved any problem you might have.
So, my guess is there was a hidden grand vision that ASP.NET code could run anywhere - server side OR client side, in a copy of Internet Explorer tied to the .NET runtime. runat="server" is just a vestigial remnant, left behind because it's client-side equivalent never made it to production.
Remember those weird ads?

Instead of CharSet.forName, using com.google.common.base.Charsets from Google's Guava (http://code.google.com/p/guava-libraries/wiki/StringsExplained#Charsets) is is slightly nicer:
InputStream is = new ByteArrayInputStream( myString.getBytes(Charsets.UTF_8) );
Which CharSet you use depends entirely on what you're going to do with the InputStream, of course.
gstreamer can handle webcam input. If I remeber well, there are python bindings for it!

I am a programmer who has to deal with a lot of code on a daily basis. Open source and what has been developed in house.
As a programmer, I find it useful to have many source files open at once, and often organise my desktop on my (widescreen) monitor so that two source files are side by side. I might be programming in both, or just reading one and programming in the other.
I find it dissatisfying and frustrating when one of those source files is >120 characters in width, because it means I can't comfortably fit a line of code on a line of screen. It upsets formatting to line wrap.
I say '120' because that's the level to which I would get annoyed at code being wider than. After that many characters, you should be splitting across lines for readability, let alone coding standards.
I write code with 80 columns in mind. This is just so that when I do leak over that boundary, it's not such a bad thing.
I adopted a SQL 2012 database where I was not a sysadmin but was an administrator on the machine. I used SSMS with "Run as Administrator", added my NT account as a SQL login and set the server role to sysadmin. No problem.
I would try triming the number to see what you get:
select len(rtrim(ltrim(userid))) from audit
if that return the correct value then just do:
select convert(int, rtrim(ltrim(userid))) from audit
if that doesn't return the correct value then I would do a replace to remove the empty space:
select convert(int, replace(userid, char(0), '')) from audit
Some other ideas not mentioned yet:
switch(true){
case in_array($p, array('home', '')):
$current_home = 'current'; break;
case preg_match('/^users\.(online|location|featured|new|browse|search|staff)$/', $p):
$current_users = 'current'; break;
case 'forum' == $p:
$current_forum = 'current'; break;
}
Someone will probably complain about readability issues with #2, but I would have no problem inheriting code like that.
Dynamically:

Via xml:
<EditText

Taken from: http://mdb-blog.blogspot.com/2015/06/mysql-find-median-nth-element-without.html
I would suggest another way, without join, but working with strings
i did not checked it with tables with large data, but small/medium tables it works just fine.
The good thing here, that it works also by GROUPING so it can return the median for several items.
here is test code for test table:
DROP TABLE test.test_median
CREATE TABLE test.test_median AS
SELECT 'book' AS grp, 4 AS val UNION ALL
SELECT 'book', 7 UNION ALL
SELECT 'book', 2 UNION ALL
SELECT 'book', 2 UNION ALL
SELECT 'book', 9 UNION ALL
SELECT 'book', 8 UNION ALL
SELECT 'book', 3 UNION ALL
SELECT 'note', 11 UNION ALL
SELECT 'bike', 22 UNION ALL
SELECT 'bike', 26
and the code for finding the median for each group:
SELECT grp,
SUBSTRING_INDEX( SUBSTRING_INDEX( GROUP_CONCAT(val ORDER BY val), ',', COUNT(*)/2 ), ',', -1) as the_median,
GROUP_CONCAT(val ORDER BY val) as all_vals_for_debug
FROM test.test_median
GROUP BY grp
Output:
grp | the_median| all_vals_for_debug
bike| 22 | 22,26
book| 4 | 2,2,3,4,7,8,9
note| 11 | 11
