This exception is probably caused by optimistic locking (or by a bug in your code). You're probably using it without knowing. And your pseudo-code (which should be replaced by real code to be able to diagnose the problem) is wrong. Hibernate saves all the modifications done to attached entities automatically. You shouldn't ever call update, merge or saveOrUpdate on an attached entity. Just do
Email email = session.get(emailId);
email.setSubject(subject);
No need to call update. Hibernate will flush the changes automatically before committing the transaction.
I guess
@foo = ("aAa", "bbb");
@bar = grep(/^aaa/i, @foo);
print join ",",@bar;
would do the trick.

'Create a class to hold the pair...

Dim rowValue As New ColumnValue
rowValue.ColumnName = item.Caption
rowValue.ColumnValue = row.item(item.Ordinal)
RowValues.Add(rowValue)
rowValue = Nothing
Next
' Now you can grab the value by the column name...
Dim results = (From p In RowValues Where p.ColumnName = "MyColumn" Select p.ColumnValue).FirstOrDefault

You are checking it the array index contains a string "undefined"
, you should either use the typeof
operator:
typeof predQuery[preId] == 'undefined'
Or use the undefined
global property:
predQuery[preId] === undefined
The first way is safer, because the undefined
global property is writable, and it can be changed to any other value.
If you need to work a lot with database in your code and you know the structure of your table, I suggest you do it as follow:
First of all you can define a class which will help you to make objects capable of keeping your table rows data. For example in my project I created a class named Document.java to keep data of a single document from my database and I made an array list of these objects to keep data of my table which is gain by a query.
package financialdocuments;
import java.lang.*;
import java.util.HashMap;
/**
*
* @author Administrator
*/
public class Document {
private int document_number;
private boolean document_type;
private boolean document_status;
private StringBuilder document_date;
private StringBuilder document_statement;
private int document_code_number;
private int document_employee_number;
private int document_client_number;
private String document_employee_name;
private String document_client_name;
private long document_amount;
private long document_payment_amount;
HashMap<Integer,Activity> document_activity_hashmap;
public Document(int dn,boolean dt,boolean ds,String dd,String dst,int dcon,int den,int dcln,long da,String dena,String dcna){
document_date = new StringBuilder(dd);
document_date.setLength(10);
document_date.setCharAt(4, '.');
document_date.setCharAt(7, '.');
document_statement = new StringBuilder(dst);
document_statement.setLength(50);
document_number = dn;
document_type = dt;
document_status = ds;
document_code_number = dcon;
document_employee_number = den;
document_client_number = dcln;
document_amount = da;
document_employee_name = dena;
document_client_name = dcna;
document_payment_amount = 0;
document_activity_hashmap = new HashMap<>();
}
public Document(int dn,boolean dt,boolean ds, long dpa){
document_number = dn;
document_type = dt;
document_status = ds;
document_payment_amount = dpa;
document_activity_hashmap = new HashMap<>();
}
// Print document information
public void printDocumentInformation (){
System.out.println("Document Number:" + document_number);
System.out.println("Document Date:" + document_date);
System.out.println("Document Type:" + document_type);
System.out.println("Document Status:" + document_status);
System.out.println("Document Statement:" + document_statement);
System.out.println("Document Code Number:" + document_code_number);
System.out.println("Document Client Number:" + document_client_number);
System.out.println("Document Employee Number:" + document_employee_number);
System.out.println("Document Amount:" + document_amount);
System.out.println("Document Payment Amount:" + document_payment_amount);
System.out.println("Document Employee Name:" + document_employee_name);
System.out.println("Document Client Name:" + document_client_name);
}
}
Second of all, you can define a class to handle your database needs. For example I defined a class named DataBase.java which handles my connections to the database and my needed queries. And I instantiated an objected of it in my main class.

I hope this could be a little help.
Late to answer but might help someone else, here is how to do it without removing the 'multiple' attribute.
$('.myDropdown').chosen({
//Here you can change the value of the maximum allowed options
max_selected_options: 1
});
This is a really interesting question, and you'll get it done in Multiple ways:
Here, In general, we have a public
schema by default. So, I'm using it as an instance.
DROP SCHEMA `public` CASCADE;
CREATE SCHEMA `public`;
GRANT ALL ON SCHEMA public TO postgres;
GRANT ALL ON SCHEMA public TO public;
If you are using PostgreSQL 9.3 or greater, you may also need to restore the default grants.
Pros:
This will clean an entire Schema and re-create it as a new one.
Cons:
You'll lose other entities too like Functions
, Views
, Materialized views
, etc.
pg_tables
table.PostgreSQL stores all the tables on its record table named pg_table
.
SELECT
'DROP TABLE IF EXISTS "' || tablename || '" CASCADE;'
from
pg_tables WHERE schemaname = 'public';
As you can see, By the use of subquery, We can remove the entire tables from the schema.
Pros:
When the other data entities are Important and you just want to delete only tables from the schema, this approach will really helpful to you.
$ sudo -u postgres psql
$ \c mydatabase
Paste these commands:
DROP SCHEMA public CASCADE;
CREATE SCHEMA public;
GRANT ALL ON SCHEMA public TO postgres;
GRANT ALL ON SCHEMA public TO public;
Note: This bunch of commands are similar to the first point, so the Pros and cons will remain the same.
Below Code snippet will surely work:
InternetExplorerOptions ops = new InternetExplorerOptions();
// ops.ignoreZoomSettings(); -- Not necessarily in case 100% zoom.
ops.introduceFlakinessByIgnoringSecurityDomains(); -- Necessary to skip protected
mode setup
System.setProperty("webdriver.ie.driver",
<path>\\IEDriverServer.exe");
WebDriver dr = new InternetExplorerDriver(ops);
In an attempt to win the prize for most dumbest reason for the problem described.
Forgetting to call
xmlhttp.send(); //yes, you need this pivotal line!
Yes, I was still getting status returns of zero from the 'open' call.
$("a").each(function() {
if (this.href.indexOf('?') != -1) {
alert("Contains questionmark");
}
});
You could try JarNavigator to view and search contents of a jar file.
In Swift 4 , just use this:
func buttonTapped(_ sender: UIButton) {
let buttonPostion = sender.convert(sender.bounds.origin, to: tableView)
if let indexPath = tableView.indexPathForRow(at: buttonPostion) {
let rowIndex = indexPath.row
}
}

This question is already a few years old but in that time some additional possibilities have evolved, like accessing the camera directly, displaying a preview and capturing snapshots (e.g. for QR code scanning).
This Google Developers article provides an in-depth explaination of all (?) the ways how to get image/camera data into a web application, from "work everywhere" (even in desktop browsers) to "work only on modern, up-to-date mobile devices with camera". Along with many useful tips.
Explained methods:
Ask for a URL: Easiest but least satisfying.
File input (covered by most other posts here): The data can then be attached to a or manipulated with JavaScript by listening for an onchange event on the input element and then reading the files property of the event target.
<input type="file" accept="image/*" id="file-input">
<script>
const fileInput = document.getElementById('file-input');
fileInput.addEventListener('change', (e) => doSomethingWithFiles(e.target.files));
</script>
The files
property is a FileList object.
<div id="target">You can drag an image file here</div>
<script>
const target = document.getElementById('target');
target.addEventListener('drop', (e) => {
e.stopPropagation();
e.preventDefault();
doSomethingWithFiles(e.dataTransfer.files);
});
target.addEventListener('dragover', (e) => {
e.stopPropagation();
e.preventDefault();
e.dataTransfer.dropEffect = 'copy';
});
</script>
You can get a FileList
object from the dataTransfer.files
property of the drop
event.
<textarea id="target">Paste an image here</textarea>
<script>
const target = document.getElementById('target');
target.addEventListener('paste', (e) => {
e.preventDefault();
doSomethingWithFiles(e.clipboardData.files);
});
</script>
e.clipboardData.files
is a FileList
object again.
const supported = 'mediaDevices' in navigator;
and prompt the user for consent. Then show a realtime preview and copy snapshots to a canvas.<video id="player" controls autoplay></video>
<button id="capture">Capture</button>
<canvas id="canvas" width=320 height=240></canvas>
<script>
const player = document.getElementById('player');
const canvas = document.getElementById('canvas');
const context = canvas.getContext('2d');
const captureButton = document.getElementById('capture');
const constraints = {
video: true,
};
captureButton.addEventListener('click', () => {
// Draw the video frame to the canvas.
context.drawImage(player, 0, 0, canvas.width, canvas.height);
});
// Attach the video stream to the video element and autoplay.
navigator.mediaDevices.getUserMedia(constraints)
.then((stream) => {
player.srcObject = stream;
});
</script>
Don't forget to stop the video stream with
player.srcObject.getVideoTracks().forEach(track => track.stop());

To get a negative version of a number in JavaScript you can always use the ~
bitwise operator.
For example, if you have a = 1000
and you need to convert it to a negative, you could do the following:
a = ~a + 1;
Which would result in a
being -1000
.
Hovercraft Full Of Eels' answer is very good, but i had to change it a bit in order to get it working on my program:
int y1 = (int) ((this.height - 2 * BORDER_GAP) - (values.get(i) * yScale - BORDER_GAP));
instead of
int y1 = (int) (scores.get(i) * yScale + BORDER_GAP);
because if i used his way the graphic would be upside down
(you'd see it if you used hardcoded values (e.g 1,3,5,7,9) instead of random values)
Assuming you can put ID's on the inputs:
$('#name').change(function() {
$('#firstname').val($(this).val());
});
Otherwise you'll have to select using the names:
$('input[name="name"]').change(function() {
$('input[name="firstname"]').val($(this).val());
});
If you're in Spring-land you can use PathMatchingResourcePatternResolver
;
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
Resource[] resources = resolver.getResources("classpath*:some/package/name/*.class");
Arrays.asList(resources).forEach(r->{
...
});
You can use HEAD request instead of GET. It will only download the header, but not the content. Then you can check the response status from the headers.
For python 2.7.x, you can use httplib
:
import httplib
c = httplib.HTTPConnection('www.example.com')
c.request("HEAD", '')
if c.getresponse().status == 200:
print('web site exists')
or urllib2
:
import urllib2
try:
urllib2.urlopen('http://www.example.com/some_page')
except urllib2.HTTPError, e:
print(e.code)
except urllib2.URLError, e:
print(e.args)
or for 2.7 and 3.x, you can install requests
import requests
request = requests.get('http://www.example.com')
if request.status_code == 200:
print('Web site exists')
else:
print('Web site does not exist')
I face Similar problem now I understand we have some more option : varStatus="loop", Here will be loop will variable which will hold the index of lop.
It can use for use to read for Zeor base index or 1 one base index.
${loop.count}` it will give 1 starting base index.
${loop.index} it will give 0 base index as normal Index of array
start from 0.
For Example :
<c:forEach var="currentImage" items="${cityBannerImages}" varStatus="loop">
<picture>
<source srcset="${currentImage}" media="(min-width: 1000px)"></source>
<source srcset="${cityMobileImages[loop.count]}" media="(min-width:600px)"></source>
<img srcset="${cityMobileImages[loop.count]}" alt=""></img>
</picture>
</c:forEach>

take a look at xp_sprintf. example below.
DECLARE @ret_string varchar (255)
EXEC xp_sprintf @ret_string OUTPUT,
'INSERT INTO %s VALUES (%s, %s)', 'table1', '1', '2'
PRINT @ret_string
Result looks like this:
INSERT INTO table1 VALUES (1, 2)
Just found an issue with the max size (255 char limit) of the string with this so there is an alternative function you can use:
create function dbo.fnSprintf (@s varchar(MAX),
@params varchar(MAX), @separator char(1) = ',')
returns varchar(MAX)
as
begin
declare @p varchar(MAX)
declare @paramlen int
set @params = @params + @separator
set @paramlen = len(@params)
while not @params = ''
begin
set @p = left(@params+@separator, charindex(@separator, @params)-1)
set @s = STUFF(@s, charindex('%s', @s), 2, @p)
set @params = substring(@params, len(@p)+2, @paramlen)
end
return @s
end
To get the same result as above you call the function as follows:
print dbo.fnSprintf('INSERT INTO %s VALUES (%s, %s)', 'table1,1,2', default)
If got your question right you want to do something like
update table
set identity_column_name = some value
Let me tell you, it is not an easy process and it is not advisable to use it, as there may be some foreign key
associated on it.
But here are steps to do it, Please take a back-up
of table
Step 1- Select design view of the table
Step 2- Turn off the identity column
Now you can use the update
query.
Now redo
the step 1 and step 2 and Turn on the identity column
Given the nature of a date/time data type it cannot contain a null
value, i.e. it needs to contain a value, it cannot be blank or contain nothing. If you mark a date/time variable as nullable
then only can you assign a null value to it. So what you are looking to do is one of two things (there might be more but I can only think of two):
Assign a minimum date/time value to your variable if you don't have a value for it. You can assign a maximum date/time value as well - whichever way suits you. Just make sure that you are consistent site-wide when checking your date/time values. Decide on using min
or max
and stick with it.
Mark your date/time variable as nullable
. This way you can set your date/time variable to null
if you don't have a variable to it.
Let me demonstrate my first point using an example. The DateTime
variable type cannot be set to null, it needs a value, in this case I am going to set it to the DateTime
's minimum value if there is no value.
My scenario is that I have a BlogPost
class. It has many different fields/properties but I chose only to use two for this example. DatePublished
is when the post was published to the website and has to contain a date/time value. DateModified
is when a post is modified, so it doesn't have to contain a value, but can contain a value.
public class BlogPost : Entity
{
public DateTime DateModified { get; set; }
public DateTime DatePublished { get; set; }
}
Using ADO.NET
to get the data from the database (assign DateTime.MinValue
is there is no value):
BlogPost blogPost = new BlogPost();
blogPost.DateModified = sqlDataReader.IsDBNull(0) ? DateTime.MinValue : sqlDataReader.GetFieldValue<DateTime>(0);
blogPost.DatePublished = sqlDataReader.GetFieldValue<DateTime>(1);
You can accomplish my second point by marking the DateModified
field as nullable
. Now you can set it to null
if there is no value for it:
public DateTime? DateModified { get; set; }
Using ADO.NET
to get the data from the database, it will look a bit different to the way it was done above (assigning null
instead of DateTime.MinValue
):
BlogPost blogPost = new BlogPost();
blogPost.DateModified = sqlDataReader.IsDBNull(0) ? (DateTime?)null : sqlDataReader.GetFieldValue<DateTime>(0);
blogPost.DatePublished = sqlDataReader.GetFieldValue<DateTime>(1);
I hope this helps to clear up any confusion. Given that my response is about 8 years later you are probably an expert C# programmer by now :)
ssh -t 'command; bash -l'
will execute the command and then start up a login shell when it completes. For example:
ssh -t [email protected] 'cd /some/path; bash -l'
Note that if you installed RVM via apt-get, you have to run some further steps than rvm implode
or apt-get remove ruby-rvm
to get it to really uninstall.
See "Installing RVM on Ubuntu".
Even I run npm install -g npm@4
, it is not ok for me.
Finally, I download and install the old node.js version.
https://nodejs.org/download/release/v7.10.1/
It is npm version 4.
You can choose any version here https://nodejs.org/download/release/
You can do that after you added the 'n' column into your df as follows.
import pandas as pd
df = pd.DataFrame({'l':['a','b','c','d'], 'v':[1,2,1,2]})
df['n'] = 0
df
l v n
0 a 1 0
1 b 2 0
2 c 1 0
3 d 2 0
# here you can add the below code and it should work.
df = df[list('nlv')]
df
n l v
0 0 a 1
1 0 b 2
2 0 c 1
3 0 d 2
However, if you have words in your columns names instead of letters. It should include two brackets around your column names.
import pandas as pd
df = pd.DataFrame({'Upper':['a','b','c','d'], 'Lower':[1,2,1,2]})
df['Net'] = 0
df['Mid'] = 2
df['Zsore'] = 2
df
Upper Lower Net Mid Zsore
0 a 1 0 2 2
1 b 2 0 2 2
2 c 1 0 2 2
3 d 2 0 2 2
# here you can add below line and it should work
df = df[list(('Mid','Upper', 'Lower', 'Net','Zsore'))]
df
Mid Upper Lower Net Zsore
0 2 a 1 0 2
1 2 b 2 0 2
2 2 c 1 0 2
3 2 d 2 0 2
Use simple FileStream.Read
then print it with Convert.ToString(b, 2)
PIL pixels are tuples, and tuples are immutable. You need to construct a new tuple. So, instead of the for loop, do:
pixels = [(pixel[0] + 20, pixel[1], pixel[2]) for pixel in pixels]
image.putdata(pixels)
Also, if the pixel is already too red, adding 20 will overflow the value. You probably want something like min(pixel[0] + 20, 255)
or int(255 * (pixel[0] / 255.) ** 0.9)
instead of pixel[0] + 20
.
And, to be able to handle images in lots of different formats, do image = image.convert("RGB")
after opening the image. The convert method will ensure that the pixels are always (r, g, b) tuples.
You can use the Unix-style -l
switch – typically terse and cryptic – or the equivalent --files-with-matches
– longer and more readable.
The output of grep --help
is not easy to read, but it's there:
-l, --files-with-matches print only names of FILEs containing matches
Take a look at toggle()
jQuery function :
Also, innerHTML
jQuery Function is .html()
.
because my array was like below: and I used .push function to create it dynamically
my_array = ["234", "23423"];
The only way I converted my array into json is
json = Object.assign({}, my_array);
One of the shortest ways would be just copy pasting the code below to the console.
var jquery = document.createElement('script');
jquery.src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js";
document.head.appendChild(jquery);
I'm not sure how necessary this is, and it adds a call to getElementById
, but if you're really keen on getting inline JavaScript out of your code, you can pass it as an HTML attribute, namely:
<span class="metadata" id="metadata-size-of-widget" title="<?php echo json_encode($size_of_widget) ?>"></span>
And then in your JavaScript:
var size_of_widget = document.getElementById("metadata-size-of-widget").title;

The following snippet of WebDriver Java code should work to launch IE. The code will ignore the setup of Protected mode settings for all zone in the IE browser.
DesiredCapabilities capabilities = DesiredCapabilities.internetExplorer();
capabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);
File file = new File("D:\\Ripon Al Wasim\\IEDriverServer.exe");
System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
WebDriver driver = new InternetExplorerDriver(capabilities);
driver.get("https://www.google.com/");
Download IEDriverServer and extract it into your desired location and set the absolute path (In my above example it was "D:\Ripon Al Wasim\IEDriverServer.exe")
I know this is a late answer but this works for me:
TimeSpan dateDifference = new TimeSpan(0,0,0, (int)endTime.Subtract(beginTime).TotalSeconds);
dateDifference should now exclude the parts smaller than a second. Works in .net 2.0 too.
In the Google docs, they've identified a pagespeed
filter that will load the script asynchronously:
ModPagespeedEnableFilters make_google_analytics_async
You can find the documentation here: https://developers.google.com/speed/pagespeed/module/filter-make-google-analytics-async
One thing to highlight is that the filter is considered high risk. From the docs:
The make_google_analytics_async filter is experimental and has not had extensive real-world testing. One case where a rewrite would cause errors is if the filter misses calls to Google Analytics methods that return values. If such methods are found, the rewrite is skipped. However, the disqualifying methods will be missed if they come before the load, are in attributes such as "onclick", or if they are in external resources. Those cases are expected to be rare.
Try this one
$('<div></div>').appendTo('body')
.html('<div><h6>Yes or No?</h6></div>')
.dialog({
modal: true, title: 'message', zIndex: 10000, autoOpen: true,
width: 'auto', resizable: false,
buttons: {
Yes: function () {
doFunctionForYes();
$(this).dialog("close");
},
No: function () {
doFunctionForNo();
$(this).dialog("close");
}
},
close: function (event, ui) {
$(this).remove();
}
});
I am not sure what the last line means. Does it mean, I read the file, create multiple Movie objects. Then make a vector of pointers where each element (pointer) points to one of those Movie objects?
I would guess this is what is intended. The intent is probably that you read the data for one movie, allocate an object with new
, fill the object in with the data, and then push the address of the data onto the vector
(probably not the best design, but most likely what's intended anyway).
It may not yield the best performance, but you can use LINQ to count the elements in an IEnumerable:
public int GetEnumerableCount(IEnumerable Enumerable)
{
return (from object Item in Enumerable
select Item).Count();
}
The asterisk is just a repetition operator, but you need to tell it what you repeat. /*abc*/
matches a string containing ab and zero or more c's (because the second * is on the c; the first is meaningless because there's nothing for it to repeat). If you want to match anything, you need to say .*
-- the dot means any character (within certain guidelines). If you want to just match abc, you could just say grep 'abc' myFile
. For your more complex match, you need to use .*
-- grep 'abc.*def' myFile
will match a string that contains abc followed by def with something optionally in between.
Update based on a comment:
*
in a regular expression is not exactly the same as * in the console. In the console, * is part of a glob construct, and just acts as a wildcard (for instance ls *.log
will list all files that end in .log). However, in regular expressions, * is a modifier, meaning that it only applies to the character or group preceding it. If you want * in regular expressions to act as a wildcard, you need to use .*
as previously mentioned -- the dot is a wildcard character, and the star, when modifying the dot, means find one or more dot; ie. find one or more of any character.
Wrap all the children inside of another LinearLayout with wrap_content
for both the width and the height as well as the vertical orientation.
it is working in my google chrome browser version 11.0.696.60
I created a simple page with no other items just basic tags and no separate CSS file and got an image
this is what i setup:
<div id="placeholder" style="width: 60px; height: 60px; border: 1px solid black; background-image: url('http://www.mypicx.com/uploadimg/1312875436_05012011_2.png')"></div>
I put an id just in case there was a hidden id tag and it works
There are two different contexts in Android. One for your application (Let's call it the BIG one) and one for each view (let's call it the activity context).
A linearLayout is a view, so you have to call the activity context. To call it from an activity, simply call "this". So easy isn't it?
When you use
this.getApplicationContext();
You call the BIG context, the one that describes your application and cannot manage your view.
A big problem with Android is that a context cannot call your activity. That's a big deal to avoid this when someone begins with the Android development. You have to find a better way to code your class (or replace "Context context" by "Activity activity" and cast it to "Context" when needed).
Regards.
Just to update my answer. The easiest way to get your Activity context
is to define a static
instance in your Activity
. For example
public class DummyActivity extends Activity
{
public static DummyActivity instance = null;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// Do some operations here
}
@Override
public void onResume()
{
super.onResume();
instance = this;
}
@Override
public void onPause()
{
super.onPause();
instance = null;
}
}
And then, in your Task
, Dialog
, View
, you could use that kind of code to get your Activity context
:
if (DummyActivity.instance != null)
{
// Do your operations with DummyActivity.instance
}
For the new Criteria since version Hibernate 5.2:
CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);
Root<SomeClass> root = criteriaQuery.from(SomeClass.class);
Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");
Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);
Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);
Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);
criteriaQuery
.select(root)
.where(predicateResult);
List<SomeClass> list = getSession()
.createQuery(criteriaQuery)
.getResultList();
None of the current answers including the accepted one will use Apple's San Francisco font on systems that don't have it installed as the system font. Since the question isn't "how do I use the OS X system font on a webpage" the correct solution is to use web fonts:
@font-face {
font-family: "San Francisco";
font-weight: 400;
src: url("https://applesocial.s3.amazonaws.com/assets/styles/fonts/sanfrancisco/sanfranciscodisplay-regular-webfont.woff");
}
I believe Zenity will do what you want. It's specifically designed for displaying GTK dialogs from the command line, and it's available as an Ubuntu package.
more generally, this could also look like this:
import multiprocessing
def chunks(l, n):
for i in range(0, len(l), n):
yield l[i:i + n]
numberOfThreads = 4
if __name__ == '__main__':
jobs = []
for i, param in enumerate(params):
p = multiprocessing.Process(target=f, args=(i,param))
jobs.append(p)
for i in chunks(jobs,numberOfThreads):
for j in i:
j.start()
for j in i:
j.join()
Of course, that way is quite cruel (since it waits for every process in a junk until it continues with the next chunk). Still it works well for approx equal run times of the function calls.
In case none of the answers work perhaps the following clarifications will help. I followed the top answer and tried to load the program with ADB from the command line to reduce the possible complications and this did not work.
Once enabling PTP mode the ADB devices command would find my Nexus 4, but I could not push to it. I had to use Eclipse and in order for the dialog to display to accept the RSA key described below.
Note: When you connect a device running Android 4.2.2 or higher to your computer, the system shows a dialog asking whether to accept an RSA key.
My select2 element was not firing the onchange
event as the drop down list offered only one value, making it impossible to change the value.
The value not having changed, no event was fired and the handler could not execute.
I then added another handler to clear the value, with the select2-open
handler being executed before the onchange
handler.
The source code now looks like:
el.on("select2-open", function(e) {
$(this).val('');
});
el.on('change', function() {
...
});
The first handler clears the value, allowing the second handler to fire up even if selecting the same value.

It is working fine. So add your base directory for your project.
If your using parse_ini_file($file) or a routine is rading an .ini file, check if you data is quoted in the ini file. Unquoted data will cause this error. Ex; data1=test will cause the error, data1="test" will not.
I object with something I keep seeing over and over in most of these answers, that what makes a function a function is that it returns a value.
A function is not just any old method that returns a value. Not so: In order for a method to be a real function it must return the same value always given a specific input. An example of a method that is not a function is the random
method in most languages, because although it does return a value the value is not always the same.
A function therefore is more akin to a map (e.g. where x -> x'
for a one dimensional function). This is a very important distinction between regular methods and functions because when dealing with real functions the timing and the order in which they are evaluated should never matter where as this is not always the case with non functions.
Here's another example of a method that is not a function but will otherwise still return a value.
// The following is pseudo code:
g(x) = {
if (morning()) {
g = 2 * x;
}
else {
g = x;
}
return g;
}
I further object to the notion that procedures do not return values. A procedure is just a specific way of talking about a function or method. So that means if the underlying method that your procedure defines or implements returns a value then, guess what that procedure returns a value. Take for example the following snippet from the SICP:
// We can immediately translate this definition into a recursive procedure
// for computing Fibonacci numbers:
(define (fib n)
(cond ((= n 0) 0)
((= n 1) 1)
(else (+ (fib (- n 1))
(fib (- n 2))))))
Have you heard of recursive procedures much lately? They are talking about a recursive function (a real function) and it's returning a value and they are using the word "procedure". So what's the difference, then?
Well another way of thinking of a function (besides the meaning mentioned above) is as an abstract representation of an ideal like the numeral 1. A procedure is that actual implementation of that thing. I personally think they are interchangeable.
(Note, if you read that chapter from the link I provide you may find that a harder concept to grasp is not the difference between a function and a procedure, but a process and a procedure. Did you know that a recursive procedure can have an iterative process?)
An analog for procedures are recipes. For example; suppose you have a machine called make-pies
this machine takes in ingredients of (fruit, milk, flower, eggs, sugar, heat)
and this machine returns a pie
.
A representation of this machine might look like
make-pies (fruit, milk, flower, eggs, sugar, heat) = {
return (heat (add fruit (mix eggs flower milk)))
}
Of course that's not the only way to make a pie.
In this case we can see that:
A function is to a machine
as a procedure is to a recipe
as attributes are to ingredients
as output is to product
That analogy is OK but it breaks down when you take into account that when you are dealing with a computer program everything is an abstraction. So unlike in the case of a recipe to a machine we are comparing two things that are themselves abstractions; two things that might as well be the same thing. And I hold that they are (for all intent and purposes) the same thing.
Well, local storage speed greatly depends on the browser the client is using, as well as the operating system. Chrome or Safari on a mac could be much faster than Firefox on a PC, especially with newer APIs. As always though, testing is your friend (I could not find any benchmarks).
I really don't see a huge difference in cookie vs local storage. Also, you should be more worried about compatibility issues: not all browsers have even begun to support the new HTML5 APIs, so cookies would be your best bet for speed and compatibility.
I was facing the same problem with wireMock while mocking the rest API calls. Earlier I was defining the server like this:
WireMockServer wireMockServer = null;
But it should be defined like as shown below:
@Rule
public WireMockRule wireMockRule = new WireMockRule(8089);
players
is a list which needs to be indexed by integers. You seem to be using it like a dictionary. Maybe you could use unpacking -- Something like:
name, score = player
(if the player
list is always a constant length).
There's not much more advice we can give you without knowing what query
is and how it works.
It's worth pointing out that the entire code you posted doesn't make a whole lot of sense. There's an IndentationError
on the second line. Also, your function is looping over some iterable, but unconditionally returning during the first iteration which isn't usually what you actually want to do.
Crude way:
The problem with the method above is that we will be doing the "find" multiple times, i.e. there is a possibility of each node getting traversed multiple times. We can overcome this problem if we can record the information so as to not process it again (think dynamic programming).
So rather than doing find every node, we keep a record of as to whats already been found.
Better Way:
Code:
struct Node *
findCA(struct Node *root, struct Node *n1, struct Node *n2, int *set) {
int left_set, right_set;
left_set = right_set = 0;
struct Node *leftCA, *rightCA;
leftCA = rightCA = NULL;
if (root == NULL) {
return NULL;
}
if (root == n1 || root == n2) {
left_set = 1;
if (n1 == n2) {
right_set = 1;
}
}
if(!left_set) {
leftCA = findCA(root->left, n1, n2, &left_set);
if (leftCA) {
return leftCA;
}
}
if (!right_set) {
rightCA= findCA(root->right, n1, n2, &right_set);
if(rightCA) {
return rightCA;
}
}
if (left_set && right_set) {
return root;
} else {
*set = (left_set || right_set);
return NULL;
}
}

You need other headers, not only access-control-allow-origin. If your request have the "Access-Control-Allow-Origin" header, you must copy it into the response headers, If doesn't, you must check the "Origin" header and copy it into the response. If your request doesn't have Access-Control-Allow-Origin not Origin headers, you must return "*".
You can read the complete explanation here: http://www.html5rocks.com/en/tutorials/cors/#toc-adding-cors-support-to-the-server
and this is the function I'm using to write cross domain headers:
func writeCrossDomainHeaders(w http.ResponseWriter, req *http.Request) {
// Cross domain headers
if acrh, ok := req.Header["Access-Control-Request-Headers"]; ok {
w.Header().Set("Access-Control-Allow-Headers", acrh[0])
}
w.Header().Set("Access-Control-Allow-Credentials", "True")
if acao, ok := req.Header["Access-Control-Allow-Origin"]; ok {
w.Header().Set("Access-Control-Allow-Origin", acao[0])
} else {
if _, oko := req.Header["Origin"]; oko {
w.Header().Set("Access-Control-Allow-Origin", req.Header["Origin"][0])
} else {
w.Header().Set("Access-Control-Allow-Origin", "*")
}
}
w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE")
w.Header().Set("Connection", "Close")

You're missing the multiplication operator. Also, you want to do 4/3

I recommend status code 422, "Unprocessable Entity".
11.2. 422 Unprocessable Entity
The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.
do this:
SELECT * FROM table ORDER BY column `name`+0 ASC
Appending the +0 will mean that:
0, 10, 11, 2, 3, 4
becomes :
0, 2, 3, 4, 10, 11
Why would the first way not work. Canvas object is created and the size is set and the grahpics are set. I always find this strange. Also if a class extends JComponent you can override the
paintComponent(){
super...
}
and then shouldn't you be able to create and instance of the class inside of another class and then just call NewlycreateinstanceOfAnyClass.repaint();
I have tried this approach for some game programming I have been working and it doesn't seem to work the way I think that it should be.

Seems odd to me that with all us speed conscious nerds here on SO no one has presented a version that uses a compile time generated look up table for the delimiter (example implementation further down). Using a look up table and iterators should beat std::regex in efficiency, if you don't need to beat regex, just use it, its standard as of C++11 and super flexible.
Some have suggested regex already but for the noobs here is a packaged example that should do exactly what the OP expects:
std::vector<std::string> split(std::string::const_iterator it, std::string::const_iterator end, std::regex e = std::regex{"\\w+"}){
std::smatch m{};
std::vector<std::string> ret{};
while (std::regex_search (it,end,m,e)) {
ret.emplace_back(m.str());
std::advance(it, m.position() + m.length()); //next start position = match position + match length
}
return ret;
}
std::vector<std::string> split(const std::string &s, std::regex e = std::regex{"\\w+"}){ //comfort version calls flexible version
return split(s.cbegin(), s.cend(), std::move(e));
}
int main ()
{
std::string str {"Some people, excluding those present, have been compile time constants - since puberty."};
auto v = split(str);
for(const auto&s:v){
std::cout << s << std::endl;
}
std::cout << "crazy version:" << std::endl;
v = split(str, std::regex{"[^e]+"}); //using e as delim shows flexibility
for(const auto&s:v){
std::cout << s << std::endl;
}
return 0;
}
If we need to be faster and accept the constraint that all chars must be 8 bits we can make a look up table at compile time using metaprogramming:
template<bool...> struct BoolSequence{}; //just here to hold bools
template<char...> struct CharSequence{}; //just here to hold chars
template<typename T, char C> struct Contains; //generic
template<char First, char... Cs, char Match> //not first specialization
struct Contains<CharSequence<First, Cs...>,Match> :
Contains<CharSequence<Cs...>, Match>{}; //strip first and increase index
template<char First, char... Cs> //is first specialization
struct Contains<CharSequence<First, Cs...>,First>: std::true_type {};
template<char Match> //not found specialization
struct Contains<CharSequence<>,Match>: std::false_type{};
template<int I, typename T, typename U>
struct MakeSequence; //generic
template<int I, bool... Bs, typename U>
struct MakeSequence<I,BoolSequence<Bs...>, U>: //not last
MakeSequence<I-1, BoolSequence<Contains<U,I-1>::value,Bs...>, U>{};
template<bool... Bs, typename U>
struct MakeSequence<0,BoolSequence<Bs...>,U>{ //last
using Type = BoolSequence<Bs...>;
};
template<typename T> struct BoolASCIITable;
template<bool... Bs> struct BoolASCIITable<BoolSequence<Bs...>>{
/* could be made constexpr but not yet supported by MSVC */
static bool isDelim(const char c){
static const bool table[256] = {Bs...};
return table[static_cast<int>(c)];
}
};
using Delims = CharSequence<'.',',',' ',':','\n'>; //list your custom delimiters here
using Table = BoolASCIITable<typename MakeSequence<256,BoolSequence<>,Delims>::Type>;
With that in place making a getNextToken
function is easy:
template<typename T_It>
std::pair<T_It,T_It> getNextToken(T_It begin,T_It end){
begin = std::find_if(begin,end,std::not1(Table{})); //find first non delim or end
auto second = std::find_if(begin,end,Table{}); //find first delim or end
return std::make_pair(begin,second);
}
Using it is also easy:
int main() {
std::string s{"Some people, excluding those present, have been compile time constants - since puberty."};
auto it = std::begin(s);
auto end = std::end(s);
while(it != std::end(s)){
auto token = getNextToken(it,end);
std::cout << std::string(token.first,token.second) << std::endl;
it = token.second;
}
return 0;
}
Here is a live example: http://ideone.com/GKtkLQ
As Luca indicated, add extra []
to your string and use the code below:
var myObject = eval('(' + myJSONtext + ')');
to test it you can use the snippet below.
var s =" [{'id':1,'name':'Test1'},{'id':2,'name':'Test2'}]";
var myObject = eval('(' + s + ')');
for (i in myObject)
{
alert(myObject[i]["name"]);
}
hope it helps..

For newbie Powershell users it is important to know that '.' is a syntactic element of Powershell, so the switch has to be enclosed in double quotes:
mvn clean install "-Dmaven.javadoc.skip=true"
This way is good and conventional:

The other posters are correct you cannot connect to MySQL directly from javascript. This is because JavaScript is at client side & mysql is server side.
So your best bet is to use ajax to call a handler as quoted above if you can let us know what language your project is in we can better help you ie php/java/.net
If you project is using php then the example from Merlyn is a good place to start, I would personally use jquery.ajax() to cut down you code and have a better chance of less cross browser issues.

You can't delete an File
array. As all of the other answers suggest, you must delete each individual file before deleting the folder...
final File[] files = outputFolder.listFiles();
for (File f: files) f.delete();
outputFolder.delete();
/Date(1383066000000)/
function convertDate(data) {
var getdate = parseInt(data.replace("/Date(", "").replace(")/", ""));
var ConvDate= new Date(getdate);
return ConvDate.getDate() + "/" + ConvDate.getMonth() + "/" + ConvDate.getFullYear();
}
git checkout {branch-name} -- {file-name}
This will use the file from the branch of choice.
I like this because posh-git
autocomplete works great with this. It also removes any ambiguity as to which branch is remote and which is local.
And --theirs
didn't work for me anyways.
With css:
.img {
display:table-cell;
max-width:...px;
max-height:...px;
width:100%;
}
Don't know if this will help anyone, but I found it useful for my purposes:
private static IEnumerable<T> PagedIterator<T>(IEnumerable<T> objectList, int PageSize)
{
var page = 0;
var recordCount = objectList.Count();
var pageCount = (int)((recordCount + PageSize)/PageSize);
if (recordCount < 1)
{
yield break;
}
while (page < pageCount)
{
var pageData = objectList.Skip(PageSize*page).Take(PageSize).ToList();
foreach (var rd in pageData)
{
yield return rd;
}
page++;
}
}
To use this you would have some linq query, and pass the result along with the page size into a foreach loop:
var results = from a in dbContext.Authors
where a.PublishDate > someDate
orderby a.Publisher
select a;
foreach(var author in PagedIterator(results, 100))
{
// Do Stuff
}
So this will iterate over each author fetching 100 authors at a time.
There is a new feature in Directory
and DirectoryInfo
in .NET 4 that allows them to return an IEnumerable
instead of an array, and start returning results before reading all the directory contents.
public bool IsDirectoryEmpty(string path)
{
IEnumerable<string> items = Directory.EnumerateFileSystemEntries(path);
using (IEnumerator<string> en = items.GetEnumerator())
{
return !en.MoveNext();
}
}
EDIT: seeing that answer again, I realize this code can be made much simpler...
public bool IsDirectoryEmpty(string path)
{
return !Directory.EnumerateFileSystemEntries(path).Any();
}
You don't need jQuery for that, you can do it with normal javascript:
http://www.w3schools.com/jsref/jsref_split.asp
var str = "a,b,c,d";
var res = str.split(","); // this returns an array
You are passing pointers (Complex*
) when your function takes references (const Complex&
). A reference and a pointer are entirely different things. When a function expects a reference argument, you need to pass it the object directly. The reference only means that the object is not copied.
To get an object to pass to your function, you would need to dereference your pointers:
Complex::distanta(*firstComplexNumber, *secondComplexNumber);
Or get your function to take pointer arguments.
However, I wouldn't really suggest either of the above solutions. Since you don't need dynamic allocation here (and you are leaking memory because you don't delete
what you have new
ed), you're better off not using pointers in the first place:
Complex firstComplexNumber(81, 93);
Complex secondComplexNumber(31, 19);
Complex::distanta(firstComplexNumber, secondComplexNumber);
You can use the try..catch statement in java, to capture an exception that may arise from Integer.parseInt().
Example:
try {
int i = Integer.parseint(stringToParse);
//parseInt succeded
} catch(Exception e)
{
//parseInt failed
}
In python, None, 0, ""(empty string), False are all accepted None.
So:
if request.GET['q']: // true if q contains anything but not ""
message
else : //// since this returns "" ant this is equals to None
error
In my case, I was able to see the backend, but in my front I was getting a blank page...
Nothing about debugging and disabling themes/plugins was useful...
After some research, I've realized that my index.php
(located at the root directory, not the theme's one) was empty!
The only content was a message saying Silence is golden.
Using a backup I had, I could get back my original index.php
and get the site working again.
Another way of solving this problem is by not relying on the correct return value from the display but relying on the Android resources resolving.
Create the file layouts.xml
in the folders res/values-land
and res/values-port
with the following content:
res/values-land/layouts.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<bool name="is_landscape">true</bool>
</resources>
res/values-port/layouts.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<bool name="is_landscape">false</bool>
</resources>
In your source code you can now access the current orientation as follows:
context.getResources().getBoolean(R.bool.is_landscape)
In Workbench 6.3 it is supereasy:
you can use,
this.props.history.push("/template", { ...response })
or
this.props.history.push("/template", { response: response })
then you can access the parsed data from /template
component by following code,
const state = this.props.location.state

For me when that usually starts happening, I have to remote desktop into the service and at the minimum restart IIS. It usually starts popping up right after I deploy code. On a few rare occasions I have had to restart the SQL services and IIS. I wrote a batch script to take a param (1 or 2) and have it setup to either do a restart of IIS ( i.e. 1), or go full nuclear (i.e. 2).
With Comodo PositiveSSL we have received 4 files.
When we followed the instructions on comodo site - we would get an error that our certificate was missing an intermediate certificate file.
Basically the syntax is
cat our_domain.crt COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt > domain-ssl_bundle.crt
plt.errorbar
can be used to plot x, y, error data (as opposed to the usual plt.plot
)
import matplotlib.pyplot as plt
import numpy as np
x = np.array([1, 2, 3, 4, 5])
y = np.power(x, 2) # Effectively y = x**2
e = np.array([1.5, 2.6, 3.7, 4.6, 5.5])
plt.errorbar(x, y, e, linestyle='None', marker='^')
plt.show()
plt.errorbar
accepts the same arguments as plt.plot
with additional yerr
and xerr
which default to None (i.e. if you leave them blank it will act as plt.plot
).

I had this problem today and it didn't have anything to do with any of the other answers. Here's what I did and how I fixed it:
A repository of mine recently moved, but I had a local copy. I branched off of my local "master" branch and made some changes--and then I remembered that the repository had moved. I used git remote set-url origin https://<my_new_repository_url>
to set the new URL but when I pushed it would just say "Everything up to date" instead of pushing my new branch to master.
I ended up solving it by rebasing onto origin/master
and then pushing with explicit branch names, like this:
$ git rebase <my_branch> origin/master
$ git push origin <my_branch>
I hope this helps anyone who had my same problem!
Try following command sequence on Ubuntu terminal:

memcmp
does not compare structure, memcmp
compares the binary, and there is always garbage in the struct, therefore it always comes out False in comparison.
Compare element by element its safe and doesn't fail.
Because you are talking about your replacement being anything, and also replacing in the middle of an element's children, it becomes more tricky than just inserting a singular element, or directly removing and appending:
function replaceTargetWith( targetID, html ){
/// find our target
var i, tmp, elm, last, target = document.getElementById(targetID);
/// create a temporary div or tr (to support tds)
tmp = document.createElement(html.indexOf('<td')!=-1?'tr':'div'));
/// fill that div with our html, this generates our children
tmp.innerHTML = html;
/// step through the temporary div's children and insertBefore our target
i = tmp.childNodes.length;
/// the insertBefore method was more complicated than I first thought so I
/// have improved it. Have to be careful when dealing with child lists as
/// they are counted as live lists and so will update as and when you make
/// changes. This is why it is best to work backwards when moving children
/// around, and why I'm assigning the elements I'm working with to `elm`
/// and `last`
last = target;
while(i--){
target.parentNode.insertBefore((elm = tmp.childNodes[i]), last);
last = elm;
}
/// remove the target.
target.parentNode.removeChild(target);
}
example usage:
replaceTargetWith( 'idTABLE', 'I <b>can</b> be <div>anything</div>' );
demo:
By using the .innerHTML
of our temporary div this will generate the TextNodes
and Elements
we need to insert without any hard work. But rather than insert the temporary div itself -- this would give us mark up that we don't want -- we can just scan and insert it's children.
...either that or look to using jQuery and it's replaceWith
method.
jQuery('#idTABLE').replaceWith('<blink>Why this tag??</blink>');
As a response to EL 2002's comment above:
It not always possible. For example, when
createElement('div')
and set its innerHTML as<td>123</td>
, this div becomes<div>123</div>
(js throws away inappropriate td tag)
The above problem obviously negates my solution as well - I have updated my code above accordingly (at least for the td
issue). However for certain HTML this will occur no matter what you do. All user agents interpret HTML via their own parsing rules, but nearly all of them will attempt to auto-correct bad HTML. The only way to achieve exactly what you are talking about (in some of your examples) is to take the HTML out of the DOM entirely, and manipulate it as a string. This will be the only way to achieve a markup string with the following (jQuery will not get around this issue either):
<table><tr>123 text<td>END</td></tr></table>
If you then take this string an inject it into the DOM, depending on the browser you will get the following:
123 text<table><tr><td>END</td></tr></table>
<table><tr><td>END</td></tr></table>
The only question that remains is why you would want to achieve broken HTML in the first place? :)
It depends what you're going for. I believe the closest thing JS has to print is:
document.write( produceMessage() );
However, it may be more prudent to place the value inside a span or a div of your choosing like:
document.getElementById("mySpanId").innerHTML = produceMessage();
Yes. Problem is in wrong notation. Use:
$this->sendRequest($uri)
Instead. Or
self::staticMethod()
for static methods. Also read this for getting idea of OOP - http://www.php.net/manual/en/language.oop5.basic.php
Using the appropriate VerificationMode:
import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
verify(mockObject, atLeast(2)).someMethod("was called at least twice");
verify(mockObject, times(3)).someMethod("was called exactly three times");
I was getting the same error but solved it finally,actually i was not setting the Object Entity which is already saved to the other entity and hence the Object value it was getting for foreeign key was null.
First you store your text file in to raw folder.
private void loadWords() throws IOException {
Log.d(TAG, "Loading words...");
final Resources resources = mHelperContext.getResources();
InputStream inputStream = resources.openRawResource(R.raw.definitions);
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
try {
String line;
while ((line = reader.readLine()) != null) {
String[] strings = TextUtils.split(line, "-");
if (strings.length < 2)
continue;
long id = addWord(strings[0].trim(), strings[1].trim());
if (id < 0) {
Log.e(TAG, "unable to add word: " + strings[0].trim());
}
}
} finally {
reader.close();
}
Log.d(TAG, "DONE loading words.");
}
Thanks for the earlier reply.
I figured out the solutions using selenium 2.0 classes.
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.ie.InternetExplorerDriver;
public class WebTableExample
{
public static void main(String[] args)
{
WebDriver driver = new InternetExplorerDriver();
driver.get("http://localhost/test/test.html");
WebElement table_element = driver.findElement(By.id("testTable"));
List<WebElement> tr_collection=table_element.findElements(By.xpath("id('testTable')/tbody/tr"));
System.out.println("NUMBER OF ROWS IN THIS TABLE = "+tr_collection.size());
int row_num,col_num;
row_num=1;
for(WebElement trElement : tr_collection)
{
List<WebElement> td_collection=trElement.findElements(By.xpath("td"));
System.out.println("NUMBER OF COLUMNS="+td_collection.size());
col_num=1;
for(WebElement tdElement : td_collection)
{
System.out.println("row # "+row_num+", col # "+col_num+ "text="+tdElement.getText());
col_num++;
}
row_num++;
}
}
}

With Parameters
return redirect()->action('UserController@profile', ['id' => 1]);

Back in 5.0 it required the entire path, now it's much simpler.
There is the Math.pow(double a, double b)
method. Note that it returns a double, you will have to cast it to an int like (int)Math.pow(double a, double b)
.
for me, this worked
exec utl_mail.send@myotherdb(
sender => '[email protected]',recipients => '[email protected],
cc => null, subject => 'my subject', message => 'my message'
);
Put this in your init function:
$.ajaxSetup({
xhrFields: {
withCredentials: true
}
});
It will work.
In simplest terms :
Keystore is used to store your credential (server or client) while truststore is used to store others credential (Certificates from CA).
Keystore is needed when you are setting up server side on SSL, it is used to store server's identity certificate, which server will present to a client on the connection while trust store setup on client side must contain to make the connection work. If you browser to connect to any website over SSL it verifies certificate presented by server against its truststore.
def iamnotglobal=100 // This will not be accessible inside the function

}
def func2()
{
log.info "My value was changed inside func to 400 . Here it is = " + iamglobal
}

func2()
here iamglobal variable is a global variable used by func and then again available to func2
if you declare variable with def it will be local, if you don't use def its global
Although this issue is quite old, i think this is relevant news / the most recent answer: Microsoft open-sourced XAML Behaviours and posted a blog post how to update to this version: https://devblogs.microsoft.com/dotnet/open-sourcing-xaml-behaviors-for-wpf/
To save you a click, this is the main steps to migrate:
To get a list of all the owning process IDs associated with each connection:
netstat -ao |find /i "listening"
If want to kill any process have the ID and use this command, so that port becomes free
Taskkill /F /IM PID of a process
Using new release of Xcode 12.5 you can simply record simulator screen using ? + R. For details you can visit here.
This error occurs when you are sending JSON data to server. Maybe in your string you are trying to add new line character by using /n.
If you add / before /n, it should work, you need to escape new line character.
"Hello there //n start coding"
The result should be as following
Hello there
start coding
$image
is in your case the value of the item and not the key. Use the following syntax to get the key too:
foreach ($images as $key => $value) {
/* … */
}
Now you can delete the item with unset($images[$key])
.
server.session.timeout
in the application.properties
file is now deprecated. The correct setting is:
server.servlet.session.timeout=60s
Also note that Tomcat will not allow you to set the timeout any less than 60 seconds. For details about that minimum setting see https://github.com/spring-projects/spring-boot/issues/7383.
The null character '\0'
(also null terminator
), abbreviated NUL
, is a control character with the value zero
. Its the same in C and objective C
The character has much more significance in C and it serves as a reserved character used to signify the end of a string
,often called a null-terminated string
The length of a C string (an array containing the characters and terminated with a '\0'
character) is found by searching for the (first) NUL byte.
Most of the jQuery Ajax methods return an XMLHttpRequest (or the equivalent) object, so you can just use abort()
.
See the documentation:
var xhr = $.ajax({
type: "POST",
url: "some.php",
data: "name=John&location=Boston",
success: function(msg){
alert( "Data Saved: " + msg );
}
});
//kill the request
xhr.abort()
UPDATE: As of jQuery 1.5 the returned object is a wrapper for the native XMLHttpRequest object called jqXHR. This object appears to expose all of the native properties and methods so the above example still works. See The jqXHR Object (jQuery API documentation).
UPDATE 2:
As of jQuery 3, the ajax method now returns a promise with extra methods (like abort), so the above code still works, though the object being returned is not an xhr
any more. See the 3.0 blog here.
UPDATE 3: xhr.abort()
still works on jQuery 3.x. Don't assume the update 2 is correct. More info on jQuery Github repository.
Don't you just want:
",".join(l)
Obviously it gets more complicated if you need to quote/escape commas etc in the values. In that case I would suggest looking at the csv module in the standard library:
Your question is: "How can I see exactly what happened in the someFunction() that caused the exception to happen?"
It seems to me that you are not asking about how to handle unforeseen exceptions in production code (as many answers assumed), but how to find out what is causing a particular exception during development.
The easiest way is to use a debugger that can stop where the uncaught exception occurs, preferably not exiting, so that you can inspect the variables. For example, PyDev in the Eclipse open source IDE can do that. To enable that in Eclipse, open the Debug perspective, select Manage Python Exception Breakpoints
in the Run
menu, and check Suspend on uncaught exceptions
.
You should consider passing the -P argument in invoking Gradle.
From Gradle Documentation :
--project-prop Sets a project property of the root project, for example -Pmyprop=myvalue. See Section 14.2, “Gradle properties and system properties”.
Considering this build.gradle
task printProp << {
println customProp
}
Invoking Gradle -PcustomProp=myProp
will give this output :
$ gradle -PcustomProp=myProp printProp
:printProp
myProp

BLEUscore
BLEU, or the Bilingual Evaluation Understudy, is a score for comparing a candidate translation of text to one or more reference translations.
A perfect match results in a score of 1.0, whereas a perfect mismatch results in a score of 0.0.
Although developed for translation, it can be used to evaluate text generated for a suite of natural language processing tasks.
Code:
import nltk
from nltk.translate import bleu
from nltk.translate.bleu_score import SmoothingFunction
smoothie = SmoothingFunction().method4
C1='Text'
C2='Best'
print('BLEUscore:',bleu([C1], C2, smoothing_function=smoothie))
Examples: By updating C1 and C2.
C1='Test' C2='Test'
BLEUscore: 1.0
C1='Test' C2='Best'
BLEUscore: 0.2326589746035907
C1='Test' C2='Text'
BLEUscore: 0.2866227639866161
You can also compare sentence similarity:
C1='It is tough.' C2='It is rough.'
BLEUscore: 0.7348889200874658
C1='It is tough.' C2='It is tough.'
BLEUscore: 1.0
You can combine filter with the text.

DISCLAIMER: I'm the author of gitchangelog of which I'll be speaking in the following.
TL;DR: You might want to check gitchangelog's own changelog or the ascii output that generated the previous.
If you want to generate a changelog from your git history, you'll probably have to consider:
Optionaly you might want some categorization (new things, changes, bugfixes)...
With all this in mind, I created and use gitchangelog. It's meant to leverage a git commit message convention to achieve all of the previous goals.
Having a commit message convention is mandatory to create a nice changelog (with or without using gitchangelog
).
commit message convention
The following are suggestions to what might be useful to think about adding in your commit messages.
You might want to separate roughly your commits into big sections:
Additionally, you could want to tag some commits:
Try to write your commit message by targeting users (functionality) as often as you can.
example
This is standard git log --oneline
to show how these information could be stored::
* 5a39f73 fix: encoding issues with non-ascii chars.
* a60d77a new: pkg: added ``.travis.yml`` for automated tests.
* 57129ba new: much greater performance on big repository by issuing only one shell command for all the commits. (fixes #7)
* 6b4b267 chg: dev: refactored out the formatting characters from GIT.
* 197b069 new: dev: reverse ``natural`` order to get reverse chronological order by default. !refactor
* 6b891bc new: add utf-8 encoding declaration !minor
So if you've noticed, the format I chose is:
{new|chg|fix}: [{dev|pkg}:] COMMIT_MESSAGE [!{minor|refactor} ... ]
To see an actual output result, you could look at the end of the PyPI page of gitchangelog
To see a full documentation of my commit message convention you can see the reference file gitchangelog.rc.reference
How to generate exquisite changelog from this
Then, it's quite easy to make a complete changelog. You could make your own script quite quickly, or use gitchangelog
.
gitchangelog
will generate a full changelog (with sectioning support as New
, Fix
...), and is reasonably configurable to your own committing conventions. It supports any type of output thanks to templating through Mustache
, Mako templating
, and has a default legacy engine written in raw python ; all current 3 engines have examples of how to use them and can output changelog's as the one displayed on the PyPI page of gitchangelog.
I'm sure you know that there are plenty of other git log
to changelog
tools out there also.
Since "$(this).parent().index();" and "$(this).parent('table').index();" don't work for me, I use this code instead:
$('td').click(function(){
var row_index = $(this).closest("tr").index();
var col_index = $(this).index();
});
You can read files in raw/res using getResources().openRawResource(R.raw.myfilename)
.
BUT there is an IDE limitation that the file name you use can only contain lower case alphanumeric characters and dot. So file names like XYZ.txt
or my_data.bin
will not be listed in R.
For those wanting to explicitly declare they are pulling from dockerhub when using fabric8 maven plugin, add a new property: <docker.pull.registry>registry.hub.docker.com/library</docker.pull.registry>
I arrived on this page trying to solve problem of pulling from my AWS ECR registry when building Docker images using fabric8.
You can use JSON with comments in it, if you load it as a text file, and then remove comments.
For example, you can use decomment library for that. Below is a complete example.
Input JSON (file input.js):
/*
* multi-line comments
**/
{
"value": 123 // one-line comment
}
Test Application:
var decomment = require('decomment');
var fs = require('fs');
fs.readFile('input.js', 'utf8', function (err, data) {
if (err) {
console.log(err);
} else {
var text = decomment(data); // removing comments
var json = JSON.parse(text); // parsing JSON
console.log(json);
}

Ansible uses the become
, become_user
, and become_method
directives to achieve privilege escalation. You can apply them to an entire play or playbook, set them in an included playbook, or set them for a particular task.
- name: checkout repo
git: repo=https://github.com/some/repo.git version=master dest={{ dst }}
become: yes
become_user: some_user
You can use become_with
to specify how the privilege escalation is achieved, the default being sudo
.
The directive is in effect for the scope of the block in which it is used (examples).
See Hosts and Users for some additional examples and Become (Privilege Escalation) for more detailed documentation.
In addition to the task-scoped become
and become_user
directives, Ansible 1.9 added some new variables and command line options to set these values for the duration of a play in the absence of explicit directives:
become
/become_user
directives.As of Ansible 2.0.2.0, the older sudo
/sudo_user
syntax described below still works, but the deprecation notice states, "This feature will be removed in a future release."
- name: checkout repo
git: repo=https://github.com/some/repo.git version=master dest={{ dst }}
sudo: yes
sudo_user: some_user
This seems to be the default behavior on iOS 10.3 based on behavior people have been witnessing in beta #2. Haven't found any official documentation about this yet so please comment if you have.
At least on the current maven version you need to add the switch -DreResolve=false if you intend to remove the dependencies from your local repo without re-downloading them.
mvn dependency:purge-local-repository -DreResolve=false
removes the dependencies without downloading them again.
Here is the official word on this from MS.

Their solution is the same as above, install the SQL Server 2008 R2 updates with the version 10.50.1777.0.
If all items are unique, you can use sets.
>>> items = set([-1, 0, 1, 2])
>>> set([1, 2]).issubset(items)
True
>>> set([1, 3]).issubset(items)
False
Most modern regex implementations allow for recursive regexpressions, which can verify a complete JSON serialized structure. The json.org specification makes it quite straightforward.
$pcre_regex = '
/
(?(DEFINE)
(?<number> -? (?= [1-9]|0(?!\d) ) \d+ (\.\d+)? ([eE] [+-]? \d+)? )
(?<boolean> true | false | null )
(?<string> " ([^"\\\\]* | \\\\ ["\\\\bfnrt\/] | \\\\ u [0-9a-f]{4} )* " )
(?<array> \[ (?: (?&json) (?: , (?&json) )* )? \s* \] )
(?<pair> \s* (?&string) \s* : (?&json) )
(?<object> \{ (?: (?&pair) (?: , (?&pair) )* )? \s* \} )
(?<json> \s* (?: (?&number) | (?&boolean) | (?&string) | (?&array) | (?&object) ) \s* )
)
\A (?&json) \Z
/six
';
It works quite well in PHP with the PCRE functions . Should work unmodified in Perl; and can certainly be adapted for other languages. Also it succeeds with the JSON test cases.
A simpler approach is the minimal consistency check as specified in RFC4627, section 6. It's however just intended as security test and basic non-validity precaution:
var my_JSON_object = !(/[^,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]/.test(
text.replace(/"(\\.|[^"\\])*"/g, ''))) &&
eval('(' + text + ')');
Ya, it's working fine, but it can enter into localhost without entering password.
You can do it in another way by following these steps:
In the browser, type: localhost/xampp/
On the left side bar menu, click Security.
Now you can see the subject table, and below the subject table you can see this link:
http://localhost/security/xamppsecurity.php.
Click this link.
Now you can set the password as you want.
Go to the xampp folder where you installed xampp. Open the xampp folder.
Find and open the phpMyAdmin folder.
Find and open the config.inc.php file with Notepad.
Find the code below:
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = true;
Replace it with the code below:
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = false;
Save the file and run the localhost/phpmyadmin with the browser.
Add a style = color:black !important;

I know this seems like noob answer but I'm putting it here so that it can help others in the future.
Suppose you are building a table with a foreach loop. And at the same time adding checkboxes at the end.
<!-- Begin Loop-->
<tr>
<td><?=$criteria?></td>
<td><?=$indicator?></td>
<td><?=$target?></td>
<td>
<div class="form-check">
<input type="checkbox" class="form-check-input" name="active" value="<?=$id?>" <?=$status?'checked':''?>>
<!-- mark as 'checked' if checkbox was selected on a previous save -->
</div>
</td>
</tr>
<!-- End of Loop -->
You place a button below the table with a hidden input:
<form method="post" action="/goalobj-review" id="goalobj">
<!-- we retrieve saved checkboxes & concatenate them into a string separated by commas.i.e. $saved_data = "1,2,3"; -->
<input type="hidden" name="result" id="selected" value="<?= $saved_data ?>>
<button type="submit" class="btn btn-info" form="goalobj">Submit Changes</button>
</form>
You can write your script like so:
<script type="text/javascript">
var checkboxes = document.getElementsByClassName('form-check-input');
var i;
var tid = setInterval(function () {
if (document.readyState !== "complete") {
return;
}
clearInterval(tid);
for(i=0;i<checkboxes.length;i++){
checkboxes[i].addEventListener('click',checkBoxValue);
}
},100);
function checkBoxValue(event) {
var selected = document.querySelector("input[id=selected]");
var result = 0;
if(this.checked) {
if(selected.value.length > 0) {
result = selected.value + "," + this.value;
document.querySelector("input[id=selected]").value = result;
} else {
result = this.value;
document.querySelector("input[id=selected]").value = result;
}
}
if(! this.checked) {
// trigger if unchecked. if checkbox is marked as 'checked' from a previous saved is deselected, this will also remove its corresponding value from our hidden input.
var compact = selected.value.split(","); // split string into array
var index = compact.indexOf(this.value); // return index of our selected checkbox
compact.splice(index,1); // removes 1 item at specified index
var newValue = compact.join(",") // returns a new string
document.querySelector("input[id=selected]").value = newValue;
}
}
</script>
The ids of your checkboxes will be submitted as a string "1,2" within the result variable. You can then break it up at the controller level however you want.
ssh-keygen -t rsa
When asked for a passphrase ,leave it blank i.e, just press enter. as simple as that!!
<script>
var today = new Date;
document.getElementById('date').innerHTML= today.toDateString();
</script>
If they are in the same directory as your script that contains:
./a.sh > /dev/null 2>&1 &
./b.sh > /dev/null 2>&1 &
The &
at the end is what makes your script run in the background.
The > /dev/null 2>&1
part is not necessary - it redirects the stdout and stderr streams so you don't have to see them on the terminal, which you may want to do for noisy scripts with lots of output.
Most basic regex is following:
(^([0-9A-Fa-f]{8}[-][0-9A-Fa-f]{4}[-][0-9A-Fa-f]{4}[-][0-9A-Fa-f]{4}[-][0-9A-Fa-f]{12})$)
or you could paste it here.
Hope this saves you some time.
Take a look at this example.
$("#wizard li").click(function () {
alert($(this).index()); // alert index of li relative to ul parent
});
SELECT DATE(ColumnName) FROM tablename;
More on MySQL DATE() function.
If you are using jQuery 1.7:
alert($(this).prop("class"));
or:
alert($(event.target).prop("class"));
we have to create your own docker volume mapped with the host directory before we mention in the docker-compose.yml as external
1.Create volume named share
docker volume create --driver local \

--opt o=bind share
2.Use it in your docker-compose
version: "3"
volumes:

According to RFC 4329 the correct MIME type for JavaScript should be application/javascript
. Howerver, older IE versions choke on this since they expect text/javascript
.
This code works on all browsers and swallows the backspace key when not on a form element, or if the form element is disabled|readOnly. It is also efficient, which is important when it is executing on every key typed in.
$(function(){
/*
* this swallows backspace keys on any non-input element.
* stops backspace -> back
*/
var rx = /INPUT|SELECT|TEXTAREA/i;
$(document).bind("keydown keypress", function(e){
if( e.which == 8 ){ // 8 == backspace
if(!rx.test(e.target.tagName) || e.target.disabled || e.target.readOnly ){
e.preventDefault();
}
}
});
});
Try this one:
$("div.subtab_left li.notebook a").click(function(e) {
e.preventDefault();
return false;
});
The above answers may help you but you may also want to know how to use array of function pointers.
void fun1()
{
}
void fun2()
{
}
void fun3()
{
}
void (*func_ptr[3])() = {fun1, fun2, fun3};
main()
{
int option;
printf("\nEnter function number you want");
printf("\nYou should not enter other than 0 , 1, 2"); /* because we have only 3 functions */
scanf("%d",&option);
if((option>=0)&&(option<=2))
{
(*func_ptr[option])();
}
return 0;
}
You can only assign the addresses of functions with the same return type and same argument types and no of arguments to a single function pointer array.
You can also pass arguments like below if all the above functions are having the same number of arguments of same type.
(*func_ptr[option])(argu1);
Note: here in the array the numbering of the function pointers will be starting from 0 same as in general arrays. So in above example fun1
can be called if option=0, fun2
can be called if option=1 and fun3
can be called if option=2.
new = text[:1] + 'Z' + text[2:]

There are several approaches:
You can normally see assembly code while debugging C++ in visual studio (and eclipse too). For this in Visual Studio put a breakpoint on code in question and when debugger hits it rigth click and find "Go To Assembly" ( or press CTRL+ALT+D )
Second approach is to generate assembly listings while compiling. For this go to project settings -> C/C++ -> Output Files -> ASM List Location and fill in file name. Also select "Assembly Output" to "Assembly With Source Code".
Compile the program and use any third-party debugger. You can use OllyDbg or WinDbg for this. Also you can use IDA (interactive disassembler). But this is hardcore way of doing it.

One reason might be if you install the node after starting the vs code,as vs code terminal integrated or external takes the path value which was at the time of starting the vs code and gives you error:
'node' is not recognized as an internal or external command,operable program or batch file.
A simple restart of vs code will solve the issue.

Can I just ask about the long term need for this facility - is it for debuging purposes?
If so, then you may want to consider using a proper debugger, such as the one found in Visual Studio, as this allows you to step through the procedure in a more controlled way, and avoids having to constantly add/remove PRINT statement from the procedure.
Just my opinion, but I prefer the debugger approach - for code and databases.
Extend Date class with this function
// Add (or substract if value is negative) the value, expresed in timeUnit
// to the date and return the new date.
Date.dateAdd = function(currentDate, value, timeUnit) {
timeUnit = timeUnit.toLowerCase();
var multiplyBy = { w:604800000,
d:86400000,
h:3600000,
m:60000,
s:1000 };
var updatedDate = new Date(currentDate.getTime() + multiplyBy[timeUnit] * value);
return updatedDate;
};
So you can add or substract a number of minutes, seconds, hours, days... to any date.
add_10_minutes_to_current_date = Date.dateAdd( Date(), 10, "m");
subs_1_hour_to_a_date = Date.dateAdd( date_value, -1, "h");
Ajax.ActionLink only sends an ajax request to the server. What happens ahead really depends upon type of data returned and what your client side script does with it. You may send a partial view for ajax call or json, xml etc. Ajax.ActionLink however have different callbacks and parameters that allow you to write js code on different events. You can do something before request is sent or onComplete
. similarly you have an onSuccess callback. This is where you put your JS code for manipulating result returned by server. You may simply put it back in UpdateTargetID or you can do fancy stuff with this result using jQuery or some other JS library.

The javadoc says this:
"Returns an immutable list containing only the specified object. The returned list is serializable."
You ask:
Why would I want to have a separate method to do that?
Primarily as a convenience ... to save you having to write a sequence of statements to:
It may also be a bit faster and/or save a bit of memory, but it is unlikely that these small savings will be significant. (An application that creates vast numbers of singleton lists is unusual to say the least.)
How does immutability play a role here?
It is part of the specification of the method; see above.
Are there any special useful use-cases for this method, rather than just being a convenience method?
Clearly, there are use-cases where it is convenient to use the singletonList
method. But I don't know how you would (objectively) distinguish between an ordinary use-case and a "specially useful" one ...
I wonder why no one does this:
Calendar time = Calendar.getInstance();

To handle spaces, @, and other unsafe characters in arbitrary locations in the url path, Use Uri.Builder in combination with a local instance of URL as I have described here:
private Uri.Builder builder;
public Uri getUriFromUrl(String thisUrl) {

builder = new Uri.Builder()
.scheme(url.getProtocol())
.authority(url.getAuthority())
.appendPath(url.getPath());

Like this:
function createJSON() {
jsonObj = [];
$("input[class=email]").each(function() {
var id = $(this).attr("title");
var email = $(this).val();
item = {}
item ["title"] = id;
item ["email"] = email;
jsonObj.push(item);
});
console.log(jsonObj);
}
Explanation
You are looking for an array of objects
. So, you create a blank array. Create an object for each input
by using 'title' and 'email' as keys. Then you add each of the objects to the array.
If you need a string, then do
jsonString = JSON.stringify(jsonObj);
Sample Output
[{"title":"QA","email":"a@b"},{"title":"PROD","email":"b@c"},{"title":"DEV","email":"c@d"}]
I installed the Role plugin under Jenkins-3.5, but it does not show the "Manage Roles" option under "Manage Jenkins", and when one follows the security install page from the wiki, all users are locked out instantly. I had to manually shutdown Jenkins on the server, restore the correct configuration settings (/me is happy to do proper backups) and restart Jenkins.
I didn't have high hopes, as that plugin was last updated in 2011
By issuing this statement:
ALTER TABLES call MODIFY incoming_Cid CHAR;
... you omitted the length parameter. Your query was therefore equivalent to:
ALTER TABLE calls MODIFY incoming_Cid CHAR(1);
You must specify the field size for sizes larger than 1:
ALTER TABLE calls MODIFY incoming_Cid CHAR(34);
The skinny is that a CPU loads data from memory addresses, stores data to memory addresses, and execute instructions sequentially out of memory addresses, with some conditional jumps in the sequence of instructions processed. Each of these three categories of instructions involves computing an address to a memory cell to be used in the machine instruction. Because machine instructions are of a variable length depending on the particular instruction involved, and because we string a variable length of them together as we build our machine code, there is a two step process involved in calculating and building any addresses.
First we laying out the allocation of memory as best we can before we can know what exactly goes in each cell. We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and building the values that will create the program as we go, and note down anyplace we need to go back and fix an address. In that place we put a dummy to just pad the location so we can continue to calculate memory size. For example our first machine code might take one cell. The next machine code might take 3 cells, involving one machine code cell and two address cells. Now our address pointer is 4. We know what goes in the machine cell, which is the op code, but we have to wait to calculate what goes in the address cells till we know where that data will be located, i.e. what will be the machine address of that data.
If there were just one source file a compiler could theoretically produce fully executable machine code without a linker. In a two pass process it could calculate all of the actual addresses to all of the data cells referenced by any machine load or store instructions. And it could calculate all of the absolute addresses referenced by any absolute jump instructions. This is how simpler compilers, like the one in Forth work, with no linker.
A linker is something that allows blocks of code to be compiled separately. This can speed up the overall process of building code, and allows some flexibility with how the blocks are later used, in other words they can be relocated in memory, for example adding 1000 to every address to scoot the block up by 1000 address cells.
So what the compiler outputs is rough machine code that is not yet fully built, but is laid out so we know the size of everything, in other words so we can start to calculate where all of the absolute addresses will be located. the compiler also outputs a list of symbols which are name/address pairs. The symbols relate a memory offset in the machine code in the module with a name. The offset being the absolute distance to the memory location of the symbol in the module.
That's where we get to the linker. The linker first slaps all of these blocks of machine code together end to end and notes down where each one starts. Then it calculates the addresses to be fixed by adding together the relative offset within a module and the absolute position of the module in the bigger layout.
Obviously I've oversimplified this so you can try to grasp it, and I have deliberately not used the jargon of object files, symbol tables, etc. which to me is part of the confusion.
Try this code:
final File f = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());
replace 'MyClass
' with your class containing the main method.
Alternatively you can also use
System.getProperty("java.class.path")
Above mentioned System property provides
Path used to find directories and JAR archives containing class files. Elements of the class path are separated by a platform-specific character specified in the path.separator property.
The ConverterParameter
property can not be bound because it is not a dependency property.
Since Binding
is not derived from DependencyObject
none of its properties can be dependency properties. As a consequence, a Binding can never be the target object of another Binding.
There is however an alternative solution. You could use a MultiBinding
with a multi-value converter instead of a normal Binding:
<Style TargetType="FrameworkElement">
<Setter Property="Visibility">
<Setter.Value>
<MultiBinding Converter="{StaticResource AccessLevelToVisibilityConverter}">
<Binding Path="Tag" RelativeSource="{RelativeSource Mode=FindAncestor,
AncestorType=UserControl}"/>
<Binding Path="Tag" RelativeSource="{RelativeSource Mode=Self}"/>
</MultiBinding>
</Setter.Value>
</Setter>
</Style>
The multi-value converter gets an array of source values as input:
public class AccessLevelToVisibilityConverter : IMultiValueConverter
{
public object Convert(
object[] values, Type targetType, object parameter, CultureInfo culture)
{
return values.All(v => (v is bool && (bool)v))
? Visibility.Visible
: Visibility.Hidden;
}
public object[] ConvertBack(
object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
throw new NotSupportedException();
}
}
memcpy expects the first two arguments to be void*.
Try:
memcpy( (void*)&RTCclk, (void*)&RTCclkBuffert, sizeof(RTCclk) );
P.S. although not necessary, convention dictates the brackets for the sizeof operator. You can get away with a lot in C that leaves code impossible to maintain, so following convention is the mark of a good (employable) C programmer.
It's better to use SecureRandom rather than just Random.
public static int generateRandomInteger(int min, int max) {
SecureRandom rand = new SecureRandom();
rand.setSeed(new Date().getTime());
int randomNum = rand.nextInt((max - min) + 1) + min;
return randomNum;
}
To remove a timezone (tzinfo) from a datetime object:
# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)
If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.
# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)
Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime
object to insert into the database. The solution is to convert your datetime.datetime
object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime
objects where one is timezone aware and another is timezone naive.
##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
arrowDt = arrowObj.to("utc").datetime
# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)
# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()
# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3
# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

Additionally, the some other thumbnails may or may not exist. Their presence is probably based on whether the video is high-quality.

You can find JavaScript and PHP scripts to retrieve thumbnails and other YouTube information in:
You can also use the YouTube Video Information Generator tool to get all the information about a YouTube video by submitting a URL or video id.
To bypass this in PHPMyAdmin or with MySQL, first remove the foreign key constraint before renaming the attribute.
(For PHPMyAdmin users: To remove FK constrains in PHPMyAdmin, select the attribute then click "relation view" next to "print view" in the toolbar below the table structure)
Does m
really need to be a data.frame()
or will a matrix()
suffice?
m <- matrix(0, ncol = 30, nrow = 2)
You can wrap a data.frame()
around that if you need to:
m <- data.frame(m)
or all in one line: m <- data.frame(matrix(0, ncol = 30, nrow = 2))
There are plenty of good answers here about reading it in chunks, I'm just gonna show you a little trick that reads all the content at once to a buffer and prints it.
I'm not saying it's better. It's not, and as Ricardo sometimes it can be bad, but I find it's a nice solution for the simple cases.
I sprinkled it with comments because there's a lot going on.
#include <stdio.h>
#include <stdlib.h>
char* ReadFile(char *filename)
{
char *buffer = NULL;
int string_size, read_size;
FILE *handler = fopen(filename, "r");
if (handler)
{
// Seek the last byte of the file
fseek(handler, 0, SEEK_END);
// Offset from the first to the last byte, or in other words, filesize
string_size = ftell(handler);
// go back to the start of the file
rewind(handler);
// Allocate a string that can hold it all
buffer = (char*) malloc(sizeof(char) * (string_size + 1) );
// Read it all in one operation
read_size = fread(buffer, sizeof(char), string_size, handler);
// fread doesn't set it so put a \0 in the last position
// and buffer is now officially a string
buffer[string_size] = '\0';
if (string_size != read_size)
{
// Something went wrong, throw away the memory and set
// the buffer to NULL
free(buffer);
buffer = NULL;
}
// Always remember to close the file.
fclose(handler);
}
return buffer;
}
int main()
{
char *string = ReadFile("yourfile.txt");
if (string)
{
puts(string);
free(string);
}
return 0;
}
Let me know if it's useful or you could learn something from it :)
You can get the id of the last transaction by running lastInsertId() method on the connection object($conn).
Like this $lid = $conn->lastInsertId();
Please check out the docs https://www.php.net/manual/en/language.oop5.basic.php
If you need the short and technical answer go right to the last section of the answer.
If you want to know better, read it all, and i hope you'll enjoy...
I countered this problem too today, and what i discovered today is that:
the above answers are true, as:
1.1 it's telling you that the header you are trying to add already exist and you should then modify its value using the appropriate property (the indexer, for instance), instead of trying to add it again.
1.2 Anytime you're changing the headers of an HttpWebRequest
, you need to use the appropriate properties on the object itself, if they exist.
Thanks FOR and Jvenema for the leading guidelines...
But, What i found out, and that was the missing piece in the puzzle is that:
2.1 The WebHeaderCollection
class is generally accessed through WebRequest
.Headers or WebResponse
.Headers. Some common headers are considered restricted and are either exposed directly by the API (such as Content-Type) or protected by the system and cannot be changed.
The restricted headers are:
Accept
Connection
Content-Length
Content-Type
Date
Expect
Host
If-Modified-Since
Range
Referer
Transfer-Encoding
User-Agent
Proxy-Connection
So, next time you are facing this exception and don't know how to solve this, remember that there are some restricted headers, and the solution is to modify their values using the appropriate property explicitly from the WebRequest
/HttpWebRequest
class.
Edit: (useful, from comments, comment by user Kaido)
Solution is to check if the header exists already or is restricted (
WebHeaderCollection.IsRestricted(key)
) before calling add
please try these
<form action="Delegate_update.php" method="post">
Name
<input type="text" name= "Name" value= "<?php echo $row['Name']; ?> "size=10>
Username
<input type="text" name= "User_name" value= "<?php echo $row['User_name']; ?> "size=10>
Password
<input type="text" name= "User_password" value= "<?php echo $row['User_password']; ?>" size=17>
<input type="submit" name= "submit" value="Update">
</form>
I think the issue would be fixed just making the html fill 100% also, might be body fills the 100% of the html but html doesn't fill 100% of the screen.
Try with:
html, body {
height: 100%;
}
Without content, the height has no value to calculate the percentage of. The width, however, will take the percentage from the DOM, if no parent is specified. (Using your example) Placing the second div inside the first div, would have rendered a result...example below...
<div id="working">
<div id="not-working"></div>
</div>
The second div would be 30% of the first div's height.
with git 1.7, there's a really easy way using git rebase
:
stage your files:
git add $files
create a new commit and re-use commit message of your "broken" commit
git commit -c master~4
prepend fixup!
in the subject line (or squash!
if you want to edit commit (message)):
fixup! Factored out some common XPath Operations
use git rebase -i --autosquash
to fixup your commit
