In Bash and zsh you can do this with Brace Expansion. This simply expands a list of items in braces. For example:
# echo {vanilla,chocolate,strawberry}-ice-cream
vanilla-ice-cream chocolate-ice-cream strawberry-ice-cream
So you can do your rename as follows:
mv {,new.}original.filename
as this expands to:
mv original.filename new.original.filename
It might be the problem if you have your home directory mounted somewhere, due nvm does not work properly with symlinks. Because I don't care where is my $NVM_DIR located I run this and all works fine:
$ mv ~/.nvm /tmp/
$ export NVM_DIR="/tmp/.nvm"
$ nvm use --delete-prefix v6.9.1
This worked for me, first cd in the directory that you would like to change the filenames to and then run the following command:
Get-ChildItem | rename-item -NewName { "house chores-" + $_.Name }
In my situation, --prefix= failed to update the path correctly under some warnings or failures. please see the below link for the answer. https://stackoverflow.com/a/50208379/1283198
If there's something about what infix and prefix mean that you don't quite understand, I'd highly suggest you reread that section of your textbook. You aren't doing yourself any favors if you come out of this with the right answer for this one problem, but still don't understand the concept.
Algorithm-wise, its pretty darn simple. You just act like a computer yourself a bit. Start by puting parens around every calculation in the order it would be calculated. Then (again in order from first calculation to last) just move the operator in front of the expression on its left hand side. After that, you can simplify by removing parens.
Copied from MSDN:
At compile time, verbatim strings are converted to ordinary strings with all the same escape sequences. Therefore, if you view a verbatim string in the debugger watch window, you will see the escape characters that were added by the compiler, not the verbatim version from your source code. For example, the verbatim string
@"C:\files.txt"
will appear in the watch window as"C:\\files.txt"
.
IIF is a non-standard T-SQL function. It was added to SQL SERVER 2012, so that Access could migrate to SQL Server without refactoring the IIF's to CASE before hand. Once the Access db is fully migrated into SQL Server, you can refactor.
If you know the number of levels in nested arrays you can simply do nested loops. Like so:
// Scan through outer loop
foreach ($tmpArray as $innerArray) {
// Check type
if (is_array($innerArray)){
// Scan through inner loop
foreach ($innerArray as $value) {
echo $value;
}
}else{
// one, two, three
echo $innerArray;
}
}
if you do not know the depth of array you need to use recursion. See example below:
// Multi-dementional Source Array
$tmpArray = array(
array("one", array(1, 2, 3)),
array("two", array(4, 5, 6)),
array("three", array(
7,
8,
array("four", 9, 10)
))
);
// Output array
displayArrayRecursively($tmpArray);
/**
* Recursive function to display members of array with indentation
*
* @param array $arr Array to process
* @param string $indent indentation string
*/
function displayArrayRecursively($arr, $indent='') {
if ($arr) {
foreach ($arr as $value) {
if (is_array($value)) {
//
displayArrayRecursively($value, $indent . '--');
} else {
// Output
echo "$indent $value \n";
}
}
}
}
The code below with display only nested array with values for your specific case (3rd level only)
$tmpArray = array(
array("one", array(1, 2, 3)),
array("two", array(4, 5, 6)),
array("three", array(7, 8, 9))
);
// Scan through outer loop
foreach ($tmpArray as $inner) {
// Check type
if (is_array($inner)) {
// Scan through inner loop
foreach ($inner[1] as $value) {
echo "$value \n";
}
}
}
# will get you the current local (session based) state.
SHOW Variables WHERE Variable_name='foreign_key_checks';
If you didn't SET GLOBAL, only your session was affected.
The error you have is because -credential
without -computername
can't exist.
You can try this way:
Invoke-Command -Credential $migratorCreds -ScriptBlock ${function:Get-LocalUsers} -ArgumentList $xmlPRE,$migratorCreds -computername YOURCOMPUTERNAME
Just a simple folder drill down.

The workaround that works in Mobile Safari at this time of writing, is to have the the third argument in addEventListener
be { passive: false }
, so the full workaround looks like this:
document.addEventListener('touchmove', function (event) {
if (event.scale !== 1) { event.preventDefault(); }
}, { passive: false });
You may want to check if options are supported to remain backwards compatible.
Check the LOB segment name from dba_lobs using the table name.
select TABLE_NAME,OWNER,COLUMN_NAME,SEGMENT_NAME from dba_lobs where TABLE_NAME='<<TABLE NAME>>';
Now use the segment name to find the bytes used in dba_segments.
select s.segment_name, s.partition_name, bytes/1048576 "Size (MB)"
from dba_segments s, dba_lobs l
where s.segment_name = l.segment_name
and s.owner = '<< OWNER >> ' order by s.segment_name, s.partition_name;
There's several ways to do it, depending on your intent.
thisSession.hasOwnProperty('merchant_id');
will tell you if thisSession has that key itself (i.e. not something it inherits from elsewhere)
"merchant_id" in thisSession
will tell you if thisSession has the key at all, regardless of where it got it.
thisSession["merchant_id"]
will return false if the key does not exist, or if its value evaluates to false for any reason (e.g. if it's a literal false
or the integer 0 and so on).
For Python 3:
{k:v for k,v in d.items() if v}
Specifying a non-static position, e.g., position: absolute/relative
on a node means that it will be used as the reference for absolutely positioned elements within it http://jsfiddle.net/E5eEk/1/
See https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Positioning#Positioning_contexts
We can change the positioning context — which element the absolutely positioned element is positioned relative to. This is done by setting positioning on one of the element's ancestors.

Not sure if it's directly related to the question, but I was looking for an answer for how to generate *.sln from cmake projects I've discovered that one can use something like this:
cmake -G "Visual Studio 10"
The example generates needed VS 2010 files from an input CMakeLists.txt file
You should be able to create and remove input field dynamically by using jquery using this method(https://www.adminspress.com/onex/view/uaomui), Even you can able to generate input fields in bulk and export to string.
You get this error if you have constrained T

An interesting pictorial representation of the equality comparison between ==

.
Source: http://dorey.github.io/JavaScript-Equality-Table/
var1 === var2
When using

for JavaScript equality testing, everything is as is. Nothing gets converted before being evaluated.
var1 == var2
When using

Moral of the story:
Use

I've used bootstrap header classes ("h1", "h2", etc.) for this. This way you get all the style benefits without using the actual tags. Here is an example:

The easiest and best answer for this question is to set a max width and height depending on your logo, the image will be a max of 50px high but no longer than 200px.
<a href="index.html">
<img src="imgs/brand-w.png" style="max-height:50px;max-width:200px;">
</a>
This will vary depending on your logo size and the nav bar items you have.
Try powershell's switch statement as an alternative, especially for variable assignment - multiple lines, but readable.
Example,
$WinVer = switch ( Test-Path $Env:windir\SysWOW64 ) {
$true { "64-bit" }
$false { "32-bit" }
}
"This version of Windows is $WinVer"
You can simply run
kubectl delete all --all --all-namespaces
The first all
means the common resource kinds (pods, replicasets, deployments, ...)
kubectl get all == kubectl get pods,rs,deployments, ...
The second --all
means to select all resources of the selected kinds
Note that all
does not include:
In order to clean up perfectly,
Those two solution require only two nested elements.
First - Relative and absolute positioning if the content is static (manual center).
.black {
position:relative;
min-height:500px;
background:rgba(0,0,0,.5);
}
.message {
position:absolute;
margin: 0 auto;
width: 180px;
top: 45%; bottom:45%; left: 0%; right: 0%;
}
https://jsfiddle.net/GlupiJas/5mv3j171/
or for fluid design - for exact content center use below example instead:
.message {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
https://jsfiddle.net/GlupiJas/w3jnjuv0/
You need 'min-height' set in case the content will exceed 50% of window height. You can also manipulate this height with media query for mobile and tablet devices . But only if You play with responsive design.
I guess You could go further and use simple JavaScript/JQuery script to manipulate the min-height or fixed height if there is a need for some reason.
Second - if content is fluid u can also use table and table-cell css properties with vertical alignment and text-align centered:
/*in a wrapper*/
display:table;
and
/*in the element inside the wrapper*/
display:table-cell;
vertical-align: middle;
text-align: center;
Works and scale perfectly, often used as responsive web design solution with grid layouts and media query that manipulate the width of the object.
.black {
display:table;
height:500px;
width:100%;
background:rgba(0,0,0,.5);
}
.message {
display:table-cell;
vertical-align: middle;
text-align: center;
}
https://jsfiddle.net/GlupiJas/4daf2v36/
I prefer table solution for exact content centering, but in some cases relative absolute positioning will do better job especially if we don't want to keep exact proportion of content alignment.
I had a moment, so, although you've already accepted an answer, I thought I'd contribute the following:
Number.prototype.between = function(a, b) {_x000D_
var min = Math.min.apply(Math, [a, b]),_x000D_
max = Math.max.apply(Math, [a, b]);_x000D_
return this > min && this < max;_x000D_
};_x000D_
_x000D_
var windowSize = 550;_x000D_
_x000D_
console.log(windowSize.between(500, 600));
_x000D_
Or, if you'd prefer to have the option to check a number is in the defined range including the end-points:
Number.prototype.between = function(a, b, inclusive) {_x000D_
var min = Math.min.apply(Math, [a, b]),_x000D_
max = Math.max.apply(Math, [a, b]);_x000D_
return inclusive ? this >= min && this <= max : this > min && this < max;_x000D_
};_x000D_
_x000D_
var windowSize = 500;_x000D_
_x000D_
console.log(windowSize.between(500, 603, true));
_x000D_
Edited to add a minor amendment to the above, given that – as noted in the comments –
…
Function.prototype.apply()
is slow! Besides calling it when you have a fixed amount of arguments is pointless…
it was worth removing the use of Function.prototype.apply()
, which yields the amended versions of the above methods, firstly without the 'inclusive' option:
Number.prototype.between = function(a, b) {_x000D_
var min = Math.min(a, b),_x000D_
max = Math.max(a, b);_x000D_
_x000D_
return this > min && this < max;_x000D_
};_x000D_
_x000D_
var windowSize = 550;_x000D_
_x000D_
console.log(windowSize.between(500, 600));
_x000D_
And with the 'inclusive' option:
Number.prototype.between = function(a, b, inclusive) {_x000D_
var min = Math.min(a, b),_x000D_
max = Math.max(a, b);_x000D_
_x000D_
return inclusive ? this >= min && this <= max : this > min && this < max;_x000D_
}_x000D_
_x000D_
var windowSize = 500;_x000D_
_x000D_
console.log(windowSize.between(500, 603, true));
_x000D_

There is the question whether we want to differentiate between cases:
"phone" : "" = the value is empty
"phone" : null = the value for "phone" was not set yet
If we want differentiate I would use null for this. Otherwise we would need to add a new field like "isAssigned" or so. This is an old Database issue.
Since String.format
is only an extension function (see here) which internally calls java.lang.String.format
you could write your own extension function using Java's DecimalFormat if you need more flexibility:
fun Double.format(fracDigits: Int): String {
val df = DecimalFormat()
df.setMaximumFractionDigits(fracDigits)
return df.format(this)
}
println(3.14159.format(2)) // 3.14

Here is how you can detect a specific Extension installed and show a warning message.
First you need to open the manifest file of the extension by going to chrome-extension://extension_id_here_hkdppipefbchgpohn/manifest.json and look for any file name within "web_accessible_resources" section.
<div class="chromewarning" style="display:none">
<script type="text/javascript">
$.get("chrome-extension://extension_id_here_hkdppipefbchgpohn/filename_found_in_ web_accessible_resources.png").done(function () {
$(".chromewarning").show();
}).fail(function () {
// alert("failed.");
});

To me, it seems as if your actual intention is to put different words on different lines. But let me answer your first question:
JLabel lab=new JLabel("text");
lab.setHorizontalAlignment(SwingConstants.LEFT);
And if you have an image:
JLabel lab=new Jlabel("text");
lab.setIcon(new ImageIcon("path//img.png"));
lab.setHorizontalTextPosition(SwingConstants.LEFT);
But, I believe you want to make the label such that there are only 2 words on 1 line.
In that case try this:
String urText="<html>You can<br>use basic HTML<br>in Swing<br> components,"
+"Hope<br> I helped!";
JLabel lac=new JLabel(urText);
lac.setAlignmentX(Component.RIGHT_ALIGNMENT);
I/O bound refers to a condition in which the time it takes to complete a computation is determined principally by the period spent waiting for input/output operations to be completed.
This is the opposite of a task being CPU bound. This circumstance arises when the rate at which data is requested is slower than the rate it is consumed or, in other words, more time is spent requesting data than processing it.
A form is not allowed to be a child element of a table
, tbody
or tr
. Attempting to put one there will tend to cause the browser to move the form to it appears after the table (while leaving its contents — table rows, table cells, inputs, etc — behind).
You can have an entire table inside a form. You can have a form inside a table cell. You cannot have part of a table inside a form.
Use one form around the entire table. Then either use the clicked submit button to determine which row to process (to be quick) or process every row (allowing bulk updates).
HTML 5 introduces the form
attribute. This allows you to provide one form per row outside the table and then associate all the form control in a given row with one of those forms using its id
.
I think you misunderstood what the java.io.File
class really represents. It is just a representation of the file on your system, i.e. its name, its path etc.
Did you even look at the Javadoc for the java.io.File
class? Have a look here
If you check the fields it has or the methods or constructor arguments, you immediately get the hint that all it is, is a representation of the URL/path.
Oracle provides quite an extensive tutorial in their Java File I/O tutorial, with the latest NIO.2 functionality too.
With NIO.2 you can read it in one line using java.nio.file.Files.readAllBytes().
Similarly you can use java.nio.file.Files.write() to write all bytes in your byte array.
UPDATE
Since the question is tagged Android, the more conventional way is to wrap the FileInputStream
in a BufferedInputStream
and then wrap that in a ByteArrayInputStream
.
That will allow you to read the contents in a byte[]
. Similarly the counterparts to them exist for the OutputStream
.

Others have addressed the inability to completely avoid an iteration variable in a for
loop, but there are options to reduce the work a tiny amount. range
has to generate a whole bunch of numbers after all, which involves a tiny amount of work; if you want to avoid even that, you can use itertools.repeat
to just get the same (ignored) value back over and over, which involves no creation/retrieval of different objects:
from itertools import repeat
for _ in repeat(None, 200): # Runs the loop 200 times
...
This will run faster in microbenchmarks than for _ in range(200):
, but if the loop body does meaningful work, it's a drop in the bucket. And unlike multiplying some anonymous sequence for your loop iterable, repeat
has only a trivial setup cost, with no memory overhead dependent on length.
The answer from Constantin is spot on but for more background this behavior is inherited from Matlab.
The Matlab behavior is explained in the Figure Setup - Displaying Multiple Plots per Figure section of the Matlab documentation.
subplot(m,n,i) breaks the figure window into an m-by-n matrix of small subplots and selects the ithe subplot for the current plot. The plots are numbered along the top row of the figure window, then the second row, and so forth.

The mongo server can still be started manual via mondgod
for development of course.
Had the same problem, I just coerced the id into a string.
My schema:
const product = new mongooseClient.Schema({
retailerID: { type: mongoose.SchemaTypes.ObjectId, required: true, index: true }
});
And then, when inserting:
retailerID: `${retailer._id}`
Looks like Calendar is the new way to go:
Calendar mydate = Calendar.getInstance();
mydate.setTimeInMillis(timestamp*1000);
out.println(mydate.get(Calendar.DAY_OF_MONTH)+"."+mydate.get(Calendar.MONTH)+"."+mydate.get(Calendar.YEAR));
The last line is just an example how to use it, this one would print eg "14.06.2012".
If you have used System.currentTimeMillis() to save the Timestamp you don't need the "*1000" part.
If you have the timestamp in a string you need to parse it first as a long: Long.parseLong(timestamp).

Difference between SASS and SCSS article explains the difference in details. Don’t be confused by the SASS and SCSS options, although I also was initially, .scss is Sassy CSS and is the next generation of .sass.
If that didn’t make sense you can see the difference in code below.
/* SCSS */
$blue: #3bbfce;
$margin: 16px;
.content-navigation {
border-color: $blue;
color: darken($blue, 9%);
}
.border {
padding: $margin / 2; margin: $margin / 2; border-color: $blue;
}
In the code above we use ; to separate the declarations. I’ve even added all the declarations for .border onto a single line to illustrate this point further. In contrast, the SASS code below must be on different lines with indentation and there is no use of the ;.
/* SASS */
$blue: #3bbfce
$margin: 16px
.content-navigation
border-color: $blue
color: darken($blue, 9%)
.border
padding: $margin / 2
margin: $margin / 2
border-color: $blue
You can see from the CSS below that the SCSS style is a lot more similar to regular CSS than the older SASS approach.
/* CSS */
.content-navigation {
border-color: #3bbfce;
color: #2b9eab;
}
.border {
padding: 8px;
margin: 8px;
border-color: #3bbfce;
}
I think most of the time these days if someone mentions that they are working with Sass they are referring to authoring in .scss rather than the traditional .sass way.
If you are working on development environment(or on for production env. it may be backup your data) then first to clear the data from the DB field or set the value as 0.
UPDATE table_mame SET field_name= 0;
After that to run the below query and after successfully run the query, to the schemamigration and after that run the migrate script.
ALTER TABLE table_mame ALTER COLUMN field_name TYPE numeric(10,0) USING field_name::numeric;
I think it will help you.
In Javascript I would use /.*_/
, meaning: match everything until _ (including)
Example:
console.log( 'hello_world'.replace(/.*_/,'') ) // 'world'
Just for other's reference, I just received this and found it was due to AngularJS. It's for backwards compatibility:
if (!event.preventDefault) {
event.preventDefault = function() {
event.returnValue = false; //ie
};
}
You have two possibilities (for an IPv4 address) :
varchar(15)
, if your want to store the IP address as a string
192.128.0.15
for instanceinteger
(4 bytes), if you convert the IP address to an integer
3229614095
for the IP I used before
The second solution will require less space in the database, and is probably a better choice, even if it implies a bit of manipulations when storing and retrieving the data (converting it from/to a string).
About those manipulations, see the ip2long()
and long2ip()
functions, on the PHP-side, or inet_aton()
and inet_ntoa()
on the MySQL-side.
All necessary git bash commands to push and pull into Github:
git status
git pull
git add filefullpath
git commit -m "comments for checkin file"
git push origin branch/master

edit filename.*
To see all branches and their commits:
git show-branch
I prefer to use regular expressions:
Regex.Replace("1112224444", @"(\d{3})(\d{3})(\d{4})", "$1-$2-$3");
1 - (change)
is bound to the HTML onchange event. The documentation about HTML onchange says the following :
Execute a JavaScript when a user changes the selected option of a
<select>
element
Source : https://www.w3schools.com/jsref/event_onchange.asp
2 - As stated before, (ngModelChange)
is bound to the model variable binded to your input.
So, my interpretation is :
(change)
triggers when the user changes the input(ngModelChange)
triggers when the model changes, whether it's consecutive to a user action or notAlso, using the StringBuilder.AppendLine method.
CODE
Intent intent = new Intent(this, SecondActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.your_notification_icon)
.setContentTitle("Notification Title")
.setContentText("Notification ")
.setContentIntent(pendingIntent );
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, mBuilder.build());
Notification can be build using Notification. Builder or NotificationCompat.Builder classes.
But if you want backward compatibility you should use NotificationCompat.Builder class as it is part of v4 Support library as it takes care of heavy lifting for providing consistent look and functionalities of Notification for API 4 and above.
A notification has 4 core properties (3 Basic display properties + 1 click action property)
Button click event is made optional on Android 3.0 and above. It means that you can build your notification using only display properties if your minSdk targets Android 3.0 or above. But if you want your notification to run on older devices than Android 3.0 then you must provide Click event otherwise you will see IllegalArgumentException.
Notification are displayed by calling notify() method of NotificationManger class
There are two variants available for notify method
notify(String tag, int id, Notification notification)
or
notify(int id, Notification notification)
notify method takes an integer id to uniquely identify your notification. However, you can also provide an optional String tag for further identification of your notification in case of conflict.
This type of conflict is rare but say, you have created some library and other developers are using your library. Now they create their own notification and somehow your notification and other dev's notification id is same then you will face conflict.
API 11 provides additional control on Notification behavior
Notification Dismissal
By default, if a user taps on notification then it performs the assigned click event but it does not clear away the notification. If you want your notification to get cleared when then you should add this
mBuilder.setAutoClear(true);
Prevent user from dismissing notification
A user may also dismiss the notification by swiping it. You can disable this default behavior by adding this while building your notification
mBuilder.setOngoing(true);
Positioning of notification
You can set the relative priority to your notification by
mBuilder.setOngoing(int pri);
If your app runs on lower API than 11 then your notification will work without above mentioned additional features. This is the advantage to choosing NotificationCompat.Builder over Notification.Builder
With the introduction of API 16, notifications were given so many new features
Notification can be so much more informative.
You can add a bigPicture to your logo. Say you get a message from a person now with the mBuilder.setLargeIcon(Bitmap bitmap) you can show that person's photo. So in the statusbar you will see the icon when you scroll you will see the person photo in place of the icon.
There are other features too
int x = 0xFF; //your number - 11111111
How do I for example read a 3 bit integer value starting at the second bit
int y = x & ( 0x7 << 2 ) // 0x7 is 111
// and you shift it 2 to the left
If you are working with Web application you can try this.
StringBuilder sb = new StringBuilder();
sb.AppendLine("Some text with line one");
sb.AppendLine("Some mpre text with line two");
MyLabel.Text = sb.ToString().Replace(Environment.NewLine, "<br />")
Check if the columns contain Nan
using .isnull()
and check for empty strings using .eq('')
, then join the two together using the bitwise OR operator |
.
Sum along axis 0
to find columns with missing data, then sum along axis 1
to the index locations for rows with missing data.
missing_cols, missing_rows = (
(df2.isnull().sum(x) | df2.eq('').sum(x))
.loc[lambda x: x.gt(0)].index
for x in (0, 1)
)
>>> df2.loc[missing_rows, missing_cols]

You could only convert a JSON array into a CSV file.
Lets say, you have a JSON like the following :
{"infile": [{"field1": 11,"field2": 12,"field3": 13},
{"field1": 21,"field2": 22,"field3": 23},
{"field1": 31,"field2": 32,"field3": 33}]}
Lets see the code for converting it to csv :
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.json.CDL;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
public class JSON2CSV {
public static void main(String myHelpers[]){
String jsonString = "{\"infile\": [{\"field1\": 11,\"field2\": 12,\"field3\": 13},{\"field1\": 21,\"field2\": 22,\"field3\": 23},{\"field1\": 31,\"field2\": 32,\"field3\": 33}]}";
JSONObject output;
try {
output = new JSONObject(jsonString);
JSONArray docs = output.getJSONArray("infile");
File file=new File("/tmp2/fromJSON.csv");
String csv = CDL.toString(docs);
FileUtils.writeStringToFile(file, csv);
} catch (JSONException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Now you got the CSV generated from JSON.
It should look like this:
field1,field2,field3
11,22,33
21,22,23
31,32,33

This website has a concise tutorial on how to use SQL Server Management Studio. As you will see you can open a "Query Window", paste your script and run it. It does not allow you to execute scripts by using the file path. However, you can do this easily by using the command line (cmd.exe):
sqlcmd -S .\SQLExpress -i SqlScript.sql
Where SqlScript.sql
is the script file name located at the current directory. See this Microsoft page for more examples
No, but it's been requested many times.
Actually, the submit button already performs this function.
Try in the FORM:
<form method="post">
<input type="submit" name="treasure" value="go!">
</form>
Then in the PHP handler:
if (isset($_POST['treasure'])){
echo "treasure will be set if the form has been submitted (to TRUE, I believe)";
}
You might also consider using the open source SpringSandwich library which lets you directly annotate in your Spring Boot controllers which interceptors to apply, much in the same way you annotate your url routes.
That way, no typo-prone Strings floating around -- SpringSandwich's method and class annotations easily survive refactoring and make it clear what's being applied where. (Disclosure: I'm the author).
I know that this topic is quite old, but this need is still alive. I read many documents, forum and script and build a new advanced one which supports compressed and uncompressed pdf :

FrameLayout is designed to block out an area on the screen to display a single item. Generally, FrameLayout should be used to hold a single child view, because it can be difficult to organize child views in a way that's scalable to different screen sizes without the children overlapping each other. You can, however, add multiple children to a FrameLayout and control their position within the FrameLayout by assigning gravity to each child, using the
android:layout_gravity
attribute.Child views are drawn in a stack, with the most recently added child on top. The size of the FrameLayout is the size of its largest child (plus padding), visible or not (if the FrameLayout's parent permits).
A RelativeLayout is a very powerful utility for designing a user interface because it can eliminate nested view groups and keep your layout hierarchy flat, which improves performance. If you find yourself using several nested LinearLayout groups, you may be able to replace them with a single RelativeLayout.
(Current docs here)
A TableLayout consists of a number of
TableRow
objects, each defining a row (actually, you can have other children, which will be explained below). TableLayout containers do not display border lines for their rows, columns, or cells. Each row has zero or more cells; each cell can hold one View object. The table has as many columns as the row with the most cells. A table can leave cells empty. Cells can span columns, as they can in HTML.The width of a column is defined by the row with the widest cell in that column.
Note: Absolute Layout is deprecated.
Try this:
String status = "The status of my combobox is " + comboBoxTest.text;
Starting Python 3.8
, the standard library provides the NormalDist
object as part of the statistics
module:
from statistics import NormalDist
def confidence_interval(data, confidence=0.95):
dist = NormalDist.from_samples(data)
z = NormalDist().inv_cdf((1 + confidence) / 2.)
h = dist.stdev * z / ((len(data) - 1) ** .5)
return dist.mean - h, dist.mean + h
This:
Creates a NormalDist
object from the data sample (NormalDist.from_samples(data)
, which gives us access to the sample's mean and standard deviation via NormalDist.mean
and NormalDist.stdev
.
Compute the Z-score
based on the standard normal distribution (represented by NormalDist()
) for the given confidence using the inverse of the cumulative distribution function (inv_cdf
).
Produces the confidence interval based on the sample's standard deviation and mean.
This assumes the sample size is big enough (let's say more than ~100 points) in order to use the standard normal distribution rather than the student's t distribution to compute the z
value.
You can fprintf to stderr, which is unbuffered, instead. Or you can flush stdout when you want to. Or you can set stdout to unbuffered.
There are different ways to do that.
df = pd.DataFrame({'Date':['01-Jun-13','03-Jun-13', '15-Aug-13', '20-Jan-14', '21-Feb-14'],
'abc':[100,-20,40,25,60],'xyz':[200,50,-5,15,80] })
def getMonth(s): return s.split("-")[1] def getDay(s): return s.split("-")[0] def getYear(s): return s.split("-")[2] def getYearMonth(s): return s.split("-")[1]+"-"+s.split("-")[2]
year
, month
, day
and 'yearMonth
'. In your case, you need one of both. You can group using two columns 'year','month'
or using one column yearMonth
df['year']= df['Date'].apply(lambda x: getYear(x)) df['month']= df['Date'].apply(lambda x: getMonth(x)) df['day']= df['Date'].apply(lambda x: getDay(x)) df['YearMonth']= df['Date'].apply(lambda x: getYearMonth(x))
Output:
Date abc xyz year month day YearMonth
0 01-Jun-13 100 200 13 Jun 01 Jun-13
1 03-Jun-13 -20 50 13 Jun 03 Jun-13
2 15-Aug-13 40 -5 13 Aug 15 Aug-13
3 20-Jan-14 25 15 14 Jan 20 Jan-14
4 21-Feb-14 60 80 14 Feb 21 Feb-14
In this case, we are grouping by two columns:
for key,g in df.groupby(['year','month']): print key,g
Output:
('13', 'Jun') Date abc xyz year month day YearMonth
0 01-Jun-13 100 200 13 Jun 01 Jun-13
1 03-Jun-13 -20 50 13 Jun 03 Jun-13
('13', 'Aug') Date abc xyz year month day YearMonth
2 15-Aug-13 40 -5 13 Aug 15 Aug-13
('14', 'Jan') Date abc xyz year month day YearMonth
3 20-Jan-14 25 15 14 Jan 20 Jan-14
('14', 'Feb') Date abc xyz year month day YearMonth
In this case, we are grouping by one column:
for key,g in df.groupby(['YearMonth']): print key,g
Output:
Jun-13 Date abc xyz year month day YearMonth
0 01-Jun-13 100 200 13 Jun 01 Jun-13
1 03-Jun-13 -20 50 13 Jun 03 Jun-13
Aug-13 Date abc xyz year month day YearMonth
2 15-Aug-13 40 -5 13 Aug 15 Aug-13
Jan-14 Date abc xyz year month day YearMonth
3 20-Jan-14 25 15 14 Jan 20 Jan-14
Feb-14 Date abc xyz year month day YearMonth
4 21-Feb-14 60 80 14 Feb 21 Feb-14
get_group
print df.groupby(['YearMonth']).get_group('Jun-13')
Output:
Date abc xyz year month day YearMonth
0 01-Jun-13 100 200 13 Jun 01 Jun-13
1 03-Jun-13 -20 50 13 Jun 03 Jun-13
get_group
. This hack would help to filter values and get the grouped values.This also would give the same result.
print df[df['YearMonth']=='Jun-13']
Output:
Date abc xyz year month day YearMonth
0 01-Jun-13 100 200 13 Jun 01 Jun-13
1 03-Jun-13 -20 50 13 Jun 03 Jun-13
You can select list of abc
or xyz
values during Jun-13
print df[df['YearMonth']=='Jun-13'].abc.values
print df[df['YearMonth']=='Jun-13'].xyz.values
Output:
[100 -20] #abc values
[200 50] #xyz values
You can use this to go through the dates that you have classified as "year-month" and apply cretiria on it to get related data.
for x in set(df.YearMonth):
print df[df['YearMonth']==x].abc.values
print df[df['YearMonth']==x].xyz.values
I recommend also to check this answer as well.
You can like this:
#{requestScope["paramName"]} ,#{sessionScope["paramName"]}
Because requestScope
or sessionScope
is a Map object.
Create your own unistd.h header and include the needed headers for function prototypes.

[
The default behavior is:
If the parameter is a primitive type (int
, bool
, double
, ...), Web API tries to get the value from the URI of the HTTP request.
For complex types (your own object, for example: Person
), Web API tries to read the value from the body of the HTTP request.
So, if you have:
...then you don't have to add any attributes (neither [FromBody]
nor [FromUri]
).
But, if you have a primitive type in the body, then you have to add [FromBody]
in front of your primitive type parameter in your WebAPI controller method. (Because, by default, WebAPI is looking for primitive types in the URI of the HTTP request.)
Or, if you have a complex type in your URI, then you must add [FromUri]
. (Because, by default, WebAPI is looking for complex types in the body of the HTTP request by default.)
Primitive types:
public class UsersController : ApiController
{
// api/users
public HttpResponseMessage Post([FromBody]int id)
{
}
// api/users/id
public HttpResponseMessage Post(int id)
{
}
}
Complex types:
public class UsersController : ApiController
{
// api/users
public HttpResponseMessage Post(User user)
{
}
// api/users/user
public HttpResponseMessage Post([FromUri]User user)
{
}
}
This works as long as you send only one parameter in your HTTP request. When sending multiple, you need to create a custom model which has all your parameters like this:
public class MyModel
{
public string MyProperty { get; set; }
public string MyProperty2 { get; set; }
}
[Route("search")]
[HttpPost]
public async Task<dynamic> Search([FromBody] MyModel model)
{
// model.MyProperty;
// model.MyProperty2;
}
From Microsoft's documentation for parameter binding in ASP.NET Web API:
When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object). At most one parameter is allowed to read from the message body.
This should work:
public HttpResponseMessage Post([FromBody] string name) { ... }
This will not work:
// Caution: This won't work! public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }
The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.

I just tried to call a function in terminal rather then MySQL Query Browser and it works. So, it looks like I'm doing something wrong in that program...
I don't know what since I called some procedures before successfully (but there where no out parameters)...
For this one I had entered
CALL my_sqrt(4,@out_value);
SELECT @out_value;
And it results with an error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT @out_value' at line 2
Strangely, if I write just:
CALL my_sqrt(4,@out_value);
The result message is: "Query canceled"
I guess, for now I will use only terminal...

json_encode
will always add slashes.
Check some examples on the manual HERE
This is because if there are some characters which needs to escaped then they will create problem.
To use the json please Parse your json to ensure that the slashes are removed
Well whether or not you remove slashesthe json will be parsed without any problem by eval.

That is a C++ standard library header file for input output streams. It includes functionality to read and write from streams. You only need to include it if you wish to use streams.
No. Servlets are not Thread safe
This is allows accessing more than one threads at a time
if u want to make it Servlet as Thread safe ., U can go for
Implement SingleThreadInterface(i)
which is a blank Interface there is no
methods
or we can go for synchronize methods
we can make whole service method as synchronized by using synchronized
keyword in front of method
Example::
public Synchronized class service(ServletRequest request,ServletResponse response)throws ServletException,IOException
or we can the put block of the code in the Synchronized block
Example::
Synchronized(Object)
{
----Instructions-----
}
I feel that Synchronized block is better than making the whole method
Synchronized
for (var i = 0; i < widthRange.length; ++i) {
if (widthRange[i] != null) {
// do something
}
}
You can't really get just the keys you've set because that's not how an Array works. Once you set element 46, you also have 0 through 45 set too (though they're null).
You could always have two arrays:
var widthRange = [], widths = [], newVal = function(n) {
widths.push(n);
return n;
};
widthRange[newVal(26)] = { whatever: "hello there" };
for (var i = 0; i < widths.length; ++i) {
doSomething(widthRange[widths[i]]);
}
edit well it may be that I'm all wet here ...
I just figure it out lately on how easy it is to make your bootstrap v3.1.1 being non-responsive. This includes navbars to not to collpase. I don't know if everyone knows this but I'd like to share it.
Two Steps to a Non-responsive Bootsrap v3.1.1
First, create a css file name it as non-responsive.css. Make sure to append it to your themes or link right after the bootstrap css files.
Second, paste this code to your non-responsive.css:
/* Template-specific stuff
*
* Customizations just for the template; these are not necessary for anything
* with disabling the responsiveness.
*/
/* Account for fixed navbar */
body {
min-width: 970px;
padding-top: 70px;
padding-bottom: 30px;
}
/* Finesse the page header spacing */
.page-header {
margin-bottom: 30px;
}
.page-header .lead {
margin-bottom: 10px;
}
/* Non-responsive overrides
*
* Utilitze the following CSS to disable the responsive-ness of the container,
* grid system, and navbar.
*/
/* Reset the container */
.container {
width: 970px;
max-width: none !important;
}
/* Demonstrate the grids */
.col-xs-4 {
padding-top: 15px;
padding-bottom: 15px;
background-color: #eee;
background-color: rgba(86,61,124,.15);
border: 1px solid #ddd;
border: 1px solid rgba(86,61,124,.2);
}
.container .navbar-header,
.container .navbar-collapse {
margin-right: 0;
margin-left: 0;
}
/* Always float the navbar header */
.navbar-header {
float: left;
}
/* Undo the collapsing navbar */
.navbar-collapse {
display: block !important;
height: auto !important;
padding-bottom: 0;
overflow: visible !important;
}
.navbar-toggle {
display: none;
}
.navbar-collapse {
border-top: 0;
}
.navbar-brand {
margin-left: -15px;
}
/* Always apply the floated nav */
.navbar-nav {
float: left;
margin: 0;
}
.navbar-nav > li {
float: left;
}
.navbar-nav > li > a {
padding: 15px;
}
/* Redeclare since we override the float above */
.navbar-nav.navbar-right {
float: right;
}
/* Undo custom dropdowns */
.navbar .navbar-nav .open .dropdown-menu {
position: absolute;
float: left;
background-color: #fff;
border: 1px solid #ccc;
border: 1px solid rgba(0, 0, 0, .15);
border-width: 0 1px 1px;
border-radius: 0 0 4px 4px;
-webkit-box-shadow: 0 6px 12px rgba(0, 0, 0, .175);
box-shadow: 0 6px 12px rgba(0, 0, 0, .175);
}
.navbar-default .navbar-nav .open .dropdown-menu > li > a {
color: #333;
}
.navbar .navbar-nav .open .dropdown-menu > li > a:hover,
.navbar .navbar-nav .open .dropdown-menu > li > a:focus,
.navbar .navbar-nav .open .dropdown-menu > .active > a,
.navbar .navbar-nav .open .dropdown-menu > .active > a:hover,
.navbar .navbar-nav .open .dropdown-menu > .active > a:focus {
color: #fff !important;
background-color: #428bca !important;
}
.navbar .navbar-nav .open .dropdown-menu > .disabled > a,
.navbar .navbar-nav .open .dropdown-menu > .disabled > a:hover,
.navbar .navbar-nav .open .dropdown-menu > .disabled > a:focus {
color: #999 !important;
background-color: transparent !important;
}
That's all and Enjoy..^^

You can make api calls by choosing the HTTP method and setting optional parameters:
$facebook->api('/me/feed/', 'post', array(
'message' => 'I want to display this message on my wall'
));
Submit Post to Facebook Wall :
Include the fbConfig.php file to connect Facebook API and get the access token.
Post message, name, link, description, and the picture will be submitted to Facebook wall. Post submission status will be shown.
If FB access token ($accessToken) is not available, the Facebook Login URL will be generated and the user would be redirected to the FB login page.
<?php
//Include FB config file
require_once 'fbConfig.php';
if(isset($accessToken)){
if(isset($_SESSION['facebook_access_token'])){
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}else{
// Put short-lived access token in session
$_SESSION['facebook_access_token'] = (string) $accessToken;
// OAuth 2.0 client handler helps to manage access tokens
$oAuth2Client = $fb->getOAuth2Client();
// Exchanges a short-lived access token for a long-lived one
$longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($_SESSION['facebook_access_token']);
$_SESSION['facebook_access_token'] = (string) $longLivedAccessToken;
// Set default access token to be used in script
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}
//FB post content
$message = 'Test message from CodexWorld.com website';
$title = 'Post From Website';
$link = 'http://www.codexworld.com/';
$description = 'CodexWorld is a programming blog.';
$picture = 'http://www.codexworld.com/wp-content/uploads/2015/12/www-codexworld-com-programming-blog.png';
$attachment = array(
'message' => $message,
'name' => $title,
'link' => $link,
'description' => $description,
'picture'=>$picture,
);
try{
//Post to Facebook
$fb->post('/me/feed', $attachment, $accessToken);
//Display post submission status
echo 'The post was submitted successfully to Facebook timeline.';
}catch(FacebookResponseException $e){
echo 'Graph returned an error: ' . $e->getMessage();
exit;
}catch(FacebookSDKException $e){
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
}else{
//Get FB login URL
$fbLoginURL = $helper->getLoginUrl($redirectURL, $fbPermissions);
//Redirect to FB login
header("Location:".$fbLoginURL);
}

This occurred when trying to connect to the WCF Service using only host name e.g. https://host/MyService.svc while using a certificate tied to a name e.g. host.mysite.com.
Switching to the https://host.mysite.com/MyService.svc and this resolved it.
using :<line number>
you can navigate to any line, thus :1
takes you to the first line.

Try
$("#deliveryNext").is(":disabled")
The following code works for me:
<script type="text/javascript">
$(document).ready(function () {
$("#testButton").button();
$("#testButton").button('disable');
alert($('#testButton').is(':disabled'));
});
</script>
<p>
<button id="testButton">Testing</button>
</p>
Alternatively,
select id from call
minus
select id from phone_number
you can use the clip
property:
#container {
position: absolute;
clip: rect(0px,200px,100px,0px);
overflow: hidden;
background: red;
}
note the position: absolute
and overflow: hidden
needed in order to get clip
to work.
You state in the comments that the returned JSON is this:
{
"dstOffset" : 3600,
"rawOffset" : 36000,
"status" : "OK",
"timeZoneId" : "Australia/Hobart",
"timeZoneName" : "Australian Eastern Daylight Time"
}
You're telling Gson that you have an array of Post
objects:
List<Post> postsList = Arrays.asList(gson.fromJson(reader,
Post[].class));
You don't. The JSON represents exactly one Post
object, and Gson is telling you that.
Change your code to be:
Post post = gson.fromJson(reader, Post.class);
Within Crystal, you can do it by creating a formula that uses the ToNumber
function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:
If NumericText ({field}) then ToNumber ({field}) else 0
Alternatively, you might find it easier to convert the field's datatype within the query used in the report.
Installing proxyconf will solve this, but behind a proxy you can't install a plugin simply using the command vagrant plugin install
, Bundler will raise an error.
set your proxy in your environment if you're using a unix like system
export http_proxy=http://user:password@host:port
or get a more detailed answer here: How to use bundler behind a proxy?
after this set up proxyconf
This is an old post, but I thought I should provide an illustrated answer anyway.
Use javascript's object notation. Like so:
states_dictionary={
"CT":["alex","harry"],
"AK":["liza","alex"],
"TX":["fred", "harry"]
};
And to access the values:
states_dictionary.AK[0] //which is liza
or you can use javascript literal object notation, whereby the keys not require to be in quotes:
states_dictionary={
CT:["alex","harry"],
AK:["liza","alex"],
TX:["fred", "harry"]
};
Use the sources tab, you can set breakpoints in JavaScript there. In the directory tree underneath it (with the up and down arrow in it), you can select the file you want to debug. You can get out of an error by pressing resume on the right-hand side of the same tab.
Elaborating to the answer of @Cephalopod, if you wanted all column names in a list you could use this oneliner:
List<String> columns =
Arrays.asList(MyClass.class.getFields())
.stream()
.filter(f -> f.getAnnotation(Column.class)!=null)
.map(f -> f.getAnnotation(Column.class).columnName())
.collect(Collectors.toList());
p:after {
content: none;
}
This is a way to remove the :after
and you can do the same for :before
Or run a pip install --upgrade pip enum34
I found the best way for me was to download unzip then symlink your new usr/java/jre-version/bin/java
to your main bin as java.
If you are using multiple forms, you can use:
<form name='myForm'>
<input type='text' name='name' value=''>
</form>
<script type="text/javascript">
document.forms['myForm']['name'].value = "New value";
</script>
As opposed to the time per unit of work (speed/latency).

The following code will show the current commit

it seems like you want something like this, that will place you string at a fixed point in a string of constant length:
Dim totallength As Integer = 100
Dim leftbuffer as Integer = 5
Dim mystring As String = "string goes here"
Dim Formatted_String as String = mystring.PadLeft(leftbuffer + mystring.Length, "-") + String.Empty.PadRight(totallength - (mystring.Length + leftbuffer), "-")
note that this will have problems if mystring.length + leftbuffer exceeds totallength
Most answers and explanations are not to explain what is a valid string of endDate
or startDate
.
Danny gave us two useful example.
$('#datepicker').datepicker({
startDate: '-2m',
endDate: '+2d'
});
But why?let's take a look at the source code at bootstrap-datetimepicker.js
.
There are some code begin line 1343 tell us how does it work.
if (/^[-+]\d+[dmwy]([\s,]+[-+]\d+[dmwy])*$/.test(date)) {
var part_re = /([-+]\d+)([dmwy])/,
parts = date.match(/([-+]\d+)([dmwy])/g),
part, dir;
date = new Date();
for (var i = 0; i < parts.length; i++) {
part = part_re.exec(parts[i]);
dir = parseInt(part[1]);
switch (part[2]) {
case 'd':
date.setUTCDate(date.getUTCDate() + dir);
break;
case 'm':
date = Datetimepicker.prototype.moveMonth.call(Datetimepicker.prototype, date, dir);
break;
case 'w':
date.setUTCDate(date.getUTCDate() + dir * 7);
break;
case 'y':
date = Datetimepicker.prototype.moveYear.call(Datetimepicker.prototype, date, dir);
break;
}
}
return UTCDate(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds(), 0);
}
There are four kinds of expressions.
w
means weekm
means monthy
means yeard
means dayLook at the regular expression ^[-+]\d+[dmwy]([\s,]+[-+]\d+[dmwy])*$
.
You can do more than these -0d
or +1m
.
Try harder like startDate:'+1y,-2m,+0d,-1w'
.And the separator ,
could be one of [\f\n\r\t\v,]
What's wrong with UNIX commands ? (given you're not working on Windows) :
ls | xargs cat | tee output.txt
does the job ( you can call it from python with subprocess if you want)
Here's a solution that avoids performing the Charset lookup for every conversion:
import java.nio.charset.Charset;
private final Charset UTF8_CHARSET = Charset.forName("UTF-8");
String decodeUTF8(byte[] bytes) {
return new String(bytes, UTF8_CHARSET);
}
byte[] encodeUTF8(String string) {
return string.getBytes(UTF8_CHARSET);
}
Here it's another approach :
function a(first,second)
{
return (second)(first);
}
a('Hello',function(e){alert(e+ ' world!');}); //=> Hello world
Just a note - I've been using wildcard selectors in jQuery to grab items that are obfuscated by ASP.NET Client IDs - this might help you too:
<asp:DropDownList id="MyDropDown" runat="server" />
$("[id* = 'MyDropDown']").append("<option value='-1'> </option>"); //etc
Note the id* wildcard- this will find your element even if the name is "ctl00$ctl00$ContentPlaceHolder1$ContentPlaceHolder1$MyDropDown"
If you like Vim, it has built-in syntax highlighting for the syslog file, e.g. it will highlight error messages in red.
vi +'syntax on' /var/log/syslog
If you don't want to wrap a table under any div:
table{
table-layout: fixed;
}
tbody{
display: block;
overflow: auto;
}
Here is a script based on Yavuz Sert's answer. It deletes all tags that are not the latest version, and their tag is greater than 950.
#!/usr/bin/env bash

Skip=0
if [[ "${Tag}" == "latest" ]]; then
Skip=1
fi
if [[ "${Tag}" -ge "950" ]]; then
Skip=1

if [[ "${Skip}" == "1" ]]; then
echo "skip ${Name} ${Tag}"
else
echo "delete ${Name} ${Tag}"

Sha="${Sha/$'\r'/}"
curl -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X DELETE "http://127.0.0.1:5000/v2/${Name}/manifests/${Sha}"
fi
}
ScanRepository(){
Name=$1
echo "Repository ${Name}"
curl -s http://127.0.0.1:5000/v2/${Name}/tags/list | jq '.tags[]' |
while IFS=$"\n" read -r line; do
line="${line%\"}"
line="${line#\"}"
CheckTag $Name $line
done
}
JqPath=$(which jq)
if [[ "x${JqPath}" == "x" ]]; then
echo "Couldn't find jq executable."
exit 2
fi
curl -s http://127.0.0.1:5000/v2/_catalog | jq '.repositories[]' |
while IFS=$"\n" read -r line; do
line="${line%\"}"
line="${line#\"}"
ScanRepository $line
done
You can also misuse File.list(FilenameFilter) (and variants) for file traversal. Short code and works in early java versions, e.g:
// list files in dir
new File(dir).list(new FilenameFilter() {
public boolean accept(File dir, String name) {
String file = dir.getAbsolutePath() + File.separator + name;
System.out.println(file);
return false;
}
});
Here is how to build a function that returns a result set that can be queried as if it were a table:
SQL> create type emp_obj is object (empno number, ename varchar2(10));
2 /
Type created.
SQL> create type emp_tab is table of emp_obj;
2 /
Type created.
SQL> create or replace function all_emps return emp_tab
2 is
3 l_emp_tab emp_tab := emp_tab();
4 n integer := 0;
5 begin
6 for r in (select empno, ename from emp)
7 loop
8 l_emp_tab.extend;
9 n := n + 1;
10 l_emp_tab(n) := emp_obj(r.empno, r.ename);
11 end loop;
12 return l_emp_tab;
13 end;
14 /
Function created.
SQL> select * from table (all_emps);
EMPNO ENAME

Encapsulation is important in any OO language, popularity has nothing to do with it. In dynamically typed languages, like PHP, it is especially useful because there is little ways to ensure a property is of a specific type without using setters.
In PHP, this works:
class Foo {
public $bar; // should be an integer
}
$foo = new Foo;
$foo->bar = "string";
In Java, it doesn't:
class Foo {
public int bar;
}
Foo myFoo = new Foo();
myFoo.bar = "string"; // error
Using magic methods (__get
and __set
) also works, but only when accessing a property that has lower visibility than the current scope can access. It can easily give you headaches when trying to debug, if it is not used properly.
Communication between controllers is done though $emit
+ $on
/ $broadcast
+ $on
methods.
So in your case you want to call a method of Controller "One" inside Controller "Two", the correct way to do this is:
app.controller('One', ['$scope', '$rootScope'
function($scope) {
$rootScope.$on("CallParentMethod", function(){
$scope.parentmethod();
});
$scope.parentmethod = function() {
// task
}
}
]);
app.controller('two', ['$scope', '$rootScope'
function($scope) {
$scope.childmethod = function() {
$rootScope.$emit("CallParentMethod", {});
}
}
]);
While $rootScope.$emit
is called, you can send any data as second parameter.
The Array.newInstance(Class<?> componentType, int length)
method is to be used to create an array with dynamically length.
Multi-dimensional arrays can be created similarly with the Array.newInstance(Class<?> componentType, int... dimensions)
method.
If you want to use jquery in a web application (e.g. React) and jquery is already loaded with <script src="jquery-3.3.1.js"...
On the webpage you can do:
npm install --save-dev @types/query
and the use it with:
let $: JQueryStatic = (window as any)["jQuery"];
so, you don't need to load jquery a second time (with npm install --save jquery
)
but have all the advantages of Typescript
(nvm maintainer here)
nvm alias default 6.11.5
if you want it pegged to that specific version.
You can also do nvm alias default 6
.
Either way, you'll want to upgrade to the latest version of nvm
(v0.33.11 as of this writing)
The ls
command has a parameter -t
to sort by time. You can then grab the first (newest) with head -1
.
ls -t b2* | head -1
But beware: Why you shouldn't parse the output of ls
My personal opinion: parsing ls
is only dangerous when the filenames can contain funny characters like spaces or newlines. If you can guarantee that the filenames will not contain funny characters then parsing ls
is quite safe.
If you are developing a script which is meant to be run by many people on many systems in many different situations then I very much do recommend to not parse ls
.
Here is how to do it "right": How can I find the latest (newest, earliest, oldest) file in a directory?
unset -v latest
for file in "$dir"/*; do
[[ $file -nt $latest ]] && latest=$file
done
The trick is to have an algorithm that only you know (such that it could be decoded at the other end).
There are simple things like, "Pick a prime number and add a magic number to it"
More convoluted options such as using asymmetric encryption of a set of binary data (that could include a unique identifier, version numbers, etc) and distribute the encrypted data as the key.
Might also be worth reading the responses to this question as well
You can by setting selectedIndex
to -1
using .prop
: http://jsfiddle.net/R9auG/.
For older jQuery versions use .attr
instead of .prop
: http://jsfiddle.net/R9auG/71/.
Use datetime.datetime.fromtimestamp
:
>>> import datetime
>>> s = 1236472051807 / 1000.0
>>> datetime.datetime.fromtimestamp(s).strftime('%Y-%m-%d %H:%M:%S.%f')
'2009-03-08 09:27:31.807000'
%f
directive is only supported by datetime.datetime.strftime
, not by time.strftime
.
UPDATE Alternative using %
, str.format
:
>>> import time
>>> s, ms = divmod(1236472051807, 1000) # (1236472051, 807)
>>> '%s.%03d' % (time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'
>>> '{}.{:03d}'.format(time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'
var elValue = "-12,erer3 4,-990.234sdsd";
var isNegetive = false;
if(elValue.indexOf("-")==0) isNegetive=true;
elValue = elValue.replace( /[^\d\.]*/g, '');
elValue = isNaN(Number(elValue)) ? 0 : Number(elValue);
if(isNegetive) elValue = 0 - elValue;
alert(elValue); //-1234990.234
Try this. Your markup:
<div id="MyId" runat="server">some content</div>
.. and in aspx.cs file:
protected void Page_Load(object sender, EventArgs e)
{
if (Session["someSessionVal"].ToString() == "some value")
{
MyId.Visible = true;
}
else
{
MyId.Visible = false;
}
}
A robust solution is to delegate counting to a subroutine invoked with call
; the subroutine uses goto
statements to emulate a loop in which shift
is used to consume the (subroutine-only) arguments iteratively:
@echo off
setlocal
:: Call the argument-counting subroutine with all arguments received,
:: without interfering with the ability to reference the arguments
:: with %1, ... later.
call :count_args %*
:: Print the result.
echo %ReturnValue% argument(s) received.
:: Exit the batch file.
exit /b
:: Subroutine that counts the arguments given.
:: Returns the count in %ReturnValue%
:count_args
set /a ReturnValue = 0
:count_args_for
if %1.==. goto :eof

For boot2docker, we can set it on /var/lib/boot2docker/profile
, for instance:
ulimit -n 2018
Be warned not to set this limit too high as it will slow down apt-get! See bug #1332440. I had it with debian jessie.

What about
Game.status[0][0] or Game.status[0]["0"] ?
Does one of these work?
PS: What you have in your question is a Javascript Object, not JSON. JSON is the 'string' version of a Javascript Object.
A way that I have done this is as follows:
At the python shell:
>>> from cryptography.fernet import Fernet
>>> key = Fernet.generate_key()
>>> print(key)
b'B8XBLJDiroM3N2nCBuUlzPL06AmfV4XkPJ5OKsPZbC4='
>>> cipher = Fernet(key)
>>> password = "thepassword".encode('utf-8')
>>> token = cipher.encrypt(password)
>>> print(token)
b'gAAAAABe_TUP82q1zMR9SZw1LpawRLHjgNLdUOmW31RApwASzeo4qWSZ52ZBYpSrb1kUeXNFoX0tyhe7kWuudNs2Iy7vUwaY7Q=='
Then, create a module with the following code:
from cryptography.fernet import Fernet
# you store the key and the token
key = b'B8XBLJDiroM3N2nCBuUlzPL06AmfV4XkPJ5OKsPZbC4='
token = b'gAAAAABe_TUP82q1zMR9SZw1LpawRLHjgNLdUOmW31RApwASzeo4qWSZ52ZBYpSrb1kUeXNFoX0tyhe7kWuudNs2Iy7vUwaY7Q=='
# create a cipher and decrypt when you need your password
cipher = Fernet(key)
mypassword = cipher.decrypt(token).decode('utf-8')
Once you've done this, you can either import mypassword directly or you can import the token and cipher to decrypt as needed.
Obviously, there are some shortcomings to this approach. If someone has both the token and the key (as they would if they have the script), they can decrypt easily. However it does obfuscate, and if you compile the code (with something like Nuitka) at least your password won't appear as plain text in a hex editor.

I think the DocumentCompleted
event will get fired for all child documents that are loaded as well (like JS and CSS, for example). You could look at the WebBrowserDocumentCompletedEventArgs
in DocumentCompleted
and check the Url property and compare that to the Url of the main page.
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'
First Record should be add
"_id" = 1 in your db
$database = "demo";
$collections ="democollaction";

$db = $m->selectDB($database);
$cursor = $collection->find()->sort(array("_id" => -1))->limit(1);
$array = iterator_to_array($cursor);

Per the Javadoc:
Returns the value of a request parameter as a String, or null if the parameter does not exist.
Do note that it is possible to submit an empty parameter - such that the parameter exists, but has no value. For example, I could include &log=&somethingElse
into the URL to enable logging, without needing to specify &log=true
. In this case, the value will be an empty String (""
).
I was using a playbook like this to test my roles locally:
---
- hosts: localhost
roles:
- role: .
but this stopped working with Ansible v2.2.
I debugged the aforementioned solution of
---
- hosts: all
tasks:
- name: Find out playbooks path
shell: pwd
register: playbook_path_output
- debug: var=playbook_path_output.stdout
and it produced my home directory and not the "current working directory"
I settled with
---
- hosts: all
roles:
- role: '{{playbook_dir}}'
per the solution above.
If you have python version 3.6 or higher you can use f strings
>>> string = "John"
>>> f"{string:<15}"
'John '
Or if you'd like it to the left
>>> f"{string:>15}"
' John'
Centered
>>> f"{string:^15}"
' John '
For more variations, feel free to check out the docs: https://docs.python.org/3/library/string.html#format-string-syntax
if you want same string output then try below else use without double quotes for proper output
$str = '20130814';
echo date('"F Y"', strtotime($str));
//output : "August 2013"
Paths under linux are separated by colons (:
), not semi-colons (;
), as theatrus correctly used it in his example. I believe Java respects this convention.
Alternatively to what andy suggested, you may use the following form (which sets CLASSPATH for the duration of the command):
CLASSPATH=".:../somejar.jar:../mysql-connector-java-5.1.6-bin.jar" java -Xmx500m ...
whichever is more convenient to you.
$(":input#single").trigger('change');
This worked for my script. I have 3 combos & bind with chainSelect event, I need to pass 3 values by url & default select all drop down. I used this
$('#machineMake').val('<?php echo $_GET['headMake']; ?>').trigger('change');
And the first event worked.
I think you are not configured properly,
if you are using XAMPP then you can easily send mail from localhost.
for example you can configure C:\xampp\php\php.ini
and c:\xampp\sendmail\sendmail.ini
for gmail to send mail.
in C:\xampp\php\php.ini
find extension=php_openssl.dll
and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.
in php.ini file find [mail function]
and change
SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"
(use the above send mail path only and it will work)
Now Open C:\xampp\sendmail\sendmail.ini
. Replace all the existing code in sendmail.ini with following code
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]
Now you have done!! create php file with mail function and send mail from localhost.
Update
First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()
).
You can set the following settings in your PHP.ini:
ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");
$ grep thestring thefile -5
-5
gets you 5
lines above and below the match 'thestring' is equivalent to -C 5
or -A 5 -B 5
.
Faced same issue on Ubuntu 16LTS when tensor flow was installed over existing python installation.
Workaround: 1.)Uninstall tensorflow from pip and pip3
sudo pip uninstall tensorflow
sudo pip3 uninstall tensorflow
2.)Uninstall python & python3
sudo apt-get remove python-dev python3-dev python-pip python3-pip
3.)Install only a single version of python(I used python 3)
sudo apt-get install python3-dev python3-pip
4.)Install tensorflow to python3
sudo pip3 install --upgrade pip
for non GPU tensorflow, run this command
sudo pip3 install --upgrade tensorflow
for GPU tensorflow, run below command
sudo pip3 install --upgrade tensorflow-gpu
Suggest not to install GPU and vanilla version of tensorflow
I have to add something to the post of Julius Tilvikas. I looked for a solution like this one he described in his post. But i think there is a mistake. I don't get realy the string between two string, i also get more with this solution, because i have to substract the lenght of the start-string. When do this, i realy get the String between two strings.
Here are my changes of his solution:
function get_string_between ($string, $start, $end, $inclusive = false){
$string = " ".$string;
if ($start == "") { $ini = 0; }
else { $ini = strpos($string, $start); }
if ($end == "") { $len = strlen($string); }
else { $len = strpos($string, $end, $ini) - $ini - strlen($start);}
if (!$inclusive) { $ini += strlen($start); }
else { $len += strlen($end); }
return substr($string, $ini, $len);
}

The direct solution would be to invoke ifPresent(consumer)
on the Optional returned by findFirst()
. This consumer will be invoked when the optional is not empty. The benefit also is that it won't throw an exception if the find operation returned an empty optional, like your current code would do; instead, nothing will happen.
If you want to return the removed value, you can map
the Optional
to the result of calling remove
:
producersProcedureActive.stream()
.filter(producer -> producer.getPod().equals(pod))
.findFirst()
.map(p -> {
producersProcedureActive.remove(p);
return p;
});
But note that the remove(Object)
operation will again traverse the list to find the element to remove. If you have a list with random access, like an ArrayList
, it would be better to make a Stream over the indexes of the list and find the first index matching the predicate:
IntStream.range(0, producersProcedureActive.size())
.filter(i -> producersProcedureActive.get(i).getPod().equals(pod))
.boxed()
.findFirst()
.map(i -> producersProcedureActive.remove((int) i));
With this solution, the remove(int)
operation operates directly on the index.
Save your dataset in CSV file and open that file and copy the dataset and paste to the excel file. and then crtl + g will work on your file, means the excel will recognize that blank is really blank.
If you don't want to have to rely on a third party tool you can use this technique:
function TestBlockHTML($replStr){
$template =
'<html>
<body>
<h1>$str</h1>
</body>
</html>';
return strtr($template, array( '$str' => $replStr));
}
Since iOS 8, you can't, it doesn't work because Apple changed internal implementation of UIActionSheet
. Please refer to Apple Documentation:
Subclassing Notes
UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.
Twood, Visibility expression is the expressions you write on how you want the "visibility" to behave. So, if you would want to hide or show the textbox, you want to write this:
=IIf((CountRows("ScannerStatisticsData")=0),True,False)
This means, if the dataset is 0, you want to hide the textbox.
I know I'm late, but I've only ever had this error if my Response.Redirect
is in a Try...Catch
block.
Never put a Response.Redirect into a Try...Catch block. It's bad practice
As an alternative to putting the Response.Redirect into the Try...Catch block, I'd break up the method/function into two steps.
inside the Try...Catch block performs the requested actions and sets a "result" value to indicate success or failure of the actions.
outside of the Try...Catch block does the redirect (or doesn't) depending on what the "result" value is.
This code is far from perfect and probably should not be copied since I haven't tested it.
public void btnLogin_Click(UserLoginViewModel model)
{
bool ValidLogin = false; // this is our "result value"
try
{
using (Context Db = new Context)
{
User User = new User();
if (String.IsNullOrEmpty(model.EmailAddress))
ValidLogin = false; // no email address was entered
else
User = Db.FirstOrDefault(x => x.EmailAddress == model.EmailAddress);
if (User != null && User.PasswordHash == Hashing.CreateHash(model.Password))
ValidLogin = true; // login succeeded
}
}
catch (Exception ex)
{
throw ex; // something went wrong so throw an error
}
if (ValidLogin)
{
GenerateCookie(User);
Response.Redirect("~/Members/Default.aspx");
}
else
{
// do something to indicate that the login failed.
}
}
Unfortunately, it appears that we can't post shares for individual topics or articles within a page. It appears Facebook just wants us to share entire pages (based on url only).
There's also their new share dialog, but even though they claim it can do all of what the old sharer.php could do, that doesn't appear to be true.
And here's Facebooks 'best practices' for sharing.
You can try df.column_name = df.column_name.astype(float)
. As for the NaN
values, you need to specify how they should be converted, but you can use the .fillna
method to do it.
Example:
In [12]: df
Out[12]:
a b
0 0.1 0.2
1 NaN 0.3
2 0.4 0.5
In [13]: df.a.values
Out[13]: array(['0.1', nan, '0.4'], dtype=object)
In [14]: df.a = df.a.astype(float).fillna(0.0)
In [15]: df
Out[15]:
a b
0 0.1 0.2
1 0.0 0.3
2 0.4 0.5
In [16]: df.a.values
Out[16]: array([ 0.1, 0. , 0.4])
POSIX is a standard for operating systems that was supposed to make it easier to write cross-platform software. It's an especially big deal in the world of Unix.
Change to:
SELECT
CASE
WHEN FRUIT = 'A' THEN 'APPLE'
WHEN FRUIT = 'B' THEN 'BANANA'
END
FROM FRUIT_TABLE;
Here is what I would recommend.
It should conform to C89, and be completely portable. In particular, it works also on pipes and sockets on POSIXy systems.
The idea is that we read the input in large-ish chunks (READALL_CHUNK
), dynamically reallocating the buffer as we need it. We only use realloc()
, fread()
, ferror()
, and free()
:
#include <stdlib.h>
#include <stdio.h>
#include <errno.h>
/* Size of each input chunk to be
read and allocate for. */
#ifndef READALL_CHUNK
#define READALL_CHUNK 262144
#endif
#define READALL_OK 0 /* Success */
#define READALL_INVALID -1 /* Invalid parameters */
#define READALL_ERROR -2 /* Stream error */
#define READALL_TOOMUCH -3 /* Too much input */
#define READALL_NOMEM -4 /* Out of memory */
/* This function returns one of the READALL_ constants above.
If the return value is zero == READALL_OK, then:
(*dataptr) points to a dynamically allocated buffer, with
(*sizeptr) chars read from the file.
The buffer is allocated for one extra char, which is NUL,
and automatically appended after the data.
Initial values of (*dataptr) and (*sizeptr) are ignored.
*/
int readall(FILE *in, char **dataptr, size_t *sizeptr)
{
char *data = NULL, *temp;
size_t size = 0;
size_t used = 0;
size_t n;
/* None of the parameters can be NULL. */
if (in == NULL || dataptr == NULL || sizeptr == NULL)
return READALL_INVALID;
/* A read error already occurred? */
if (ferror(in))
return READALL_ERROR;
while (1) {
if (used + READALL_CHUNK + 1 > size) {
size = used + READALL_CHUNK + 1;
/* Overflow check. Some ANSI C compilers
may optimize this away, though. */
if (size <= used) {
free(data);
return READALL_TOOMUCH;
}
temp = realloc(data, size);
if (temp == NULL) {
free(data);
return READALL_NOMEM;
}
data = temp;
}
n = fread(data + used, 1, READALL_CHUNK, in);
if (n == 0)
break;
used += n;
}
if (ferror(in)) {
free(data);
return READALL_ERROR;
}
temp = realloc(data, used + 1);
if (temp == NULL) {
free(data);
return READALL_NOMEM;
}
data = temp;
data[used] = '\0';
*dataptr = data;
*sizeptr = used;
return READALL_OK;
}
Above, I've used a constant chunk size, READALL_CHUNK
== 262144 (256*1024
). This means that in the worst case, up to 262145 chars are wasted (allocated but not used), but only temporarily. At the end, the function reallocates the buffer to the optimal size. Also, this means that we do four reallocations per megabyte of data read.
The 262144-byte default in the code above is a conservative value; it works well for even old minilaptops and Raspberry Pis and most embedded devices with at least a few megabytes of RAM available for the process. Yet, it is not so small that it slows down the operation (due to many read calls, and many buffer reallocations) on most systems.
For desktop machines at this time (2017), I recommend a much larger READALL_CHUNK
, perhaps #define READALL_CHUNK 2097152
(2 MiB).
Because the definition of READALL_CHUNK
is guarded (i.e., it is defined only if it is at that point in the code still undefined), you can override the default value at compile time, by using (in most C compilers) -DREADALL_CHUNK=2097152
command-line option -- but do check your compiler options for defining a preprocessor macro using command-line options.
Your array has default keys(0,1) which store object {'com':'some thing'}
use:
var obj = jQuery.parseJSON(response);
$.each(obj, function(key,value) {
alert(value.com);
});
In case you are using GITBASH terminal
"set NODE_ENV=production"
will not work, what can you do is type
"export NODE_ENV=production"
import cv2
image = cv2.imread(tiff_file.tif)
cv2.imshow('tif image',image)
I am adding this for completeness as this post hits high in Google search results.
You can actually copy all from a regex search, just not in one step.
In this case background-color:rgba(0,0,0,0.5);
is the best way.
For example: background-color:rgba(0,0,0,opacity option);
Maybe this is a bit redundant, but no one appeared to have mentioned this as a solution.
As a beginner in SQL I find that when using a BEGIN
and END
SSMS usually adds a squiggly line with incorrect syntax near 'END'
to END, simply because there's no content in between yet. If you're just setting up BEGIN
and END
to get started and add the actual query later, then simply add a bogus PRINT
statement so SSMS stops bothering you.
For example:
IF (1=1)
BEGIN
PRINT 'BOGUS'
END
The following will indeed set you on the wrong track, thinking you made a syntax error which in this case just means you still need to add content in between BEGIN and END:
IF (1=1)
BEGIN
END
You can do it (albeit not lightning-quickly) like so:
people.Where(p => !people.Any(q => (p != q && p.Id == q.Id)));
That is, "select all people where there isn't another different person in the list with the same ID."
Mind you, in your example, that would just select person 3. I'm not sure how to tell which you want, out of the previous two.
Someone already suggested https://github.com/Shougo/vimshell.vim, but they didn't mention why. Consequently, when I came away from this question I wasted a lot of other time trying the other (much higher ranked) options.
Shougo/vimshell is the answer. Here's why:
In addition to being a terminal emulator, VimShell allows you to navigate through terminal output in normal and visual mode. Thus, if a command you run results in output that you'd like to copy and paste using the keyboard only...VimShell covers this.
None of the other options mentioned, including the :terminal command in NeoVim do this. Neovim's :terminal comes close, but falls short in at least the following ways as of 2/18/2017:
Moves the cursor to the end of the buffer, instead of at the last keeping it in the same spot like VimShell does. Huge waste of time.
Doesn't support modifiable = 1
see a discussion on this at Github, so helpful plugins like vim-easymotion can't be used.
Doesn't support the display of line numbers like Vimshell does.
Don't waste time on the other options, including Neovim's :terminal. Go with VimShell.
I have approximately these problem. I need debug AngularJs application from Visual Studio 2013.
By default IIS Express restricted access to local files (like json).
But, first: JSON have JavaScript syntax.
Second: javascript files is allowed.
So:
rename JSON to JS (data.json->data.js
).
correct load command ($http.get('App/data.js').success(function (data) {...
load script data.js to page (<script src="App/data.js"></script>
)
Next use loaded data an usual manner. It is just workaround, of course.

If you wish to use CV2, you need to use the resize
function.
For example, this will resize both axes by half:
small = cv2.resize(image, (0,0), fx=0.5, fy=0.5)
and this will resize the image to have 100 cols (width) and 50 rows (height):
resized_image = cv2.resize(image, (100, 50))
Another option is to use scipy
module, by using:
small = scipy.misc.imresize(image, 0.5)
There are obviously more options you can read in the documentation of those functions (cv2.resize, scipy.misc.imresize).
Update:
According to the SciPy documentation:
imresize
is deprecated in SciPy 1.0.0, and will be removed in 1.2.0.
Useskimage.transform.resize
instead.
Note that if you're looking to resize by a factor, you may actually want skimage.transform.rescale
.
Why not use a mechanism similar to Apache cron jobs? http://en.wikipedia.org/wiki/Cron
For calendar\scheduling I'd use slightly different values for "bits" to accommodate standard calendar reoccurence events - instead of [day of week (0 - 7), month (1 - 12), day of month (1 - 31), hour (0 - 23), min (0 - 59)]
-- I'd use something like [Year (repeat every N years), month (1 - 12), day of month (1 - 31), week of month (1-5), day of week (0 - 7)]
Hope this helps.

You can use Jquery's on method and listen for the scroll
event.
From the documentation of String.split(String regex)
:
This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
So you will have to use the two argument version String.split(String regex, int limit)
with a negative value:
String[] split = data.split("\\|",-1);
Doc:
If the limit n is greater than zero then the pattern will be applied at most n - 1 times, the array's length will be no greater than n, and the array's last entry will contain all input beyond the last matched delimiter. If n is non-positive then the pattern will be applied as many times as possible and the array can have any length. If n is zero then the pattern will be applied as many times as possible, the array can have any length, and trailing empty strings will be discarded.
This will not leave out any empty elements, including the trailing ones.
plot(t)
is in this case the same as
plot(t[[1]], t[[2]])
As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1
:
> length(t)
[1] 4
> length(1)
[1] 1
In your second example you plot a list with elements named x
and y
, both vectors of length 2,
so plot
plots these two vectors.
Edit:
If you want to plot lines use

This is the reason why mkv is such a good container, especially now that it's mature:
mkvmerge -o output.mkv video.mp4 subtitle.srt
Put the navbar out of your container:
<div class="navbar">
<div class="navbar-inner">
<!-- nav bar items here -->
</div>
</div>
<div class="container">
</div>
EDIT:
Here is one that I did with responsive navbar. The code fits the document body:
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<!-- .btn-navbar is used as the toggle for collapsed navbar content -->
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<!-- Be sure to leave the brand out there if you want it shown -->
<a class="brand" href="#">Project name</a>
<!-- Everything you want hidden at 940px or less, place within here -->
<div class="nav-collapse">
<!-- .nav, .navbar-search, .navbar-form, etc -->
<ul class="nav">
<li class="active"><a href="#">Home</a></li>
<li class="divider-vertical"></li>
<li><a href="#">Link</a></li>
<li class="divider-vertical"></li>
<li><a href="#">Link</a></li>
</ul>
<ul class="nav pull-right">
<li><a href="#">Log out</a></li>
</ul>
</div>
</div>
</div>
</div>
<div class="container">
<div class="row">
<div class="span12">
</div>
</div>
</div> <!-- end container -->

A view is simply any SELECT
query that has been given a name and saved in the database. For this reason, a view is sometimes called a named query or a stored query. To create a view, you use the SQL syntax:
CREATE OR REPLACE VIEW <view_name> AS
SELECT <any valid select query>;
It is possible and is deceptively easy:
bin\Debug
folder below the project file (.csproj).app.publish
folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).
As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce the probability of a user to have to install .NET.
It works. We use this method during development and test to avoid having to constantly uninstall and install the application and still being quite close to how the final application will run.
Hmm.. what class is your constructor for? Probably some class extending JFrame? The window focus should be at the window, of course but I don't think that's the problem.
I expanded your code, tried to run it and it worked - the key presses resulted as print output. (run with Ubuntu through Eclipse):
public class MyFrame extends JFrame {
public MyFrame() {
System.out.println("test");
addKeyListener(new KeyListener() {
public void keyPressed(KeyEvent e) {
System.out.println("tester");
}
public void keyReleased(KeyEvent e) {
System.out.println("2test2");
}
public void keyTyped(KeyEvent e) {
System.out.println("3test3");
}
});
}
public static void main(String[] args) {
MyFrame f = new MyFrame();
f.pack();
f.setVisible(true);
}
}
