Hi
I want to know that we always use Sorting algorithm like (Insertion Sort or Merge Sort,...) just for lists and arrays?? and we do not use these algorithms for stack or queue ???
thanks
To get any code with SoftReference<T> to be fully tested, one must come up with some way to test the 'yup, it's been nulled' case. One might more or less mock this by using a 'for-test' code path to force the reference to be null, but that won't manage the queue exactly as the GC does. I wonder if anyone out can share experience in setting up a repeatable, controlled, environment, in which the GC is, in fact, provoked into collecting and nulling?
In SQL Profiler you can see that very simple updates to a table by primary key take about 10-30ms each. On about every 10th update the write column shows 1, on all other updates it shows 0. This must mean that about every 10th update statement still requires disk IO. I wonder why that is. Would it not be more efficient queue up all IO until the transaction commits?
Hey,
Im having an issue defining the hit area for a javascript sliding element.
See example:
http://www.warface.co.uk/clients/warface.co.uk/
Please slide over the grey box on the right side to reveal the button, although this works I would only like for the slider to only be triggered by rolling over the red block.
CSS
.slidingtwitter { /* -- This is the hit area -- */
background: #ccc;
width:255px;
height:55px;
overflow: hidden;
top:50%;
right: 0px; /* -- This is the sliding start point -- */
position: fixed;
font-family: Gotham, Sans-Serif;
z-index: 50;
}
.slidingtwitter.right {
right:0px;
}
.slidingtwitter .caption { /* -- This is the sliding area -- */
background: #fff;
position: absolute;
width:260px;
height:55px;
right: -205px; /* -- This is the sliding start point -- */
}
.slidingtwitter a {
color: #484848;
font-size: 20px;
text-transform: uppercase;
}
.slidingtwitter a:hover {
color: black;
}
.slidingtwitter .smaller {
font-size: 12px;
font-family: Gotham Medium;
}
.twitterblock {
background: #f35555 url("styles/images/button_twitter.png") no-repeat 14px 15px ;
width:35px;
height:35px;
padding:10px;
float:left;
display:block;
}
.slidingtwitter .followme {
background: url("styles/images/button_arrowheadthin.jpg")no-repeat right 0;
height:35px;
display:block;
float:left;
line-height:14px;
width:140px;
margin:10px 0px 0px 14px;
padding-top:6px;
padding-right: 40px;
}
JS
$('.slidingtwitter').hover(function(){
$(".slide", this).stop().animate({right:'0px'},{queue:false,duration:400}); //Position on rollover
},function() {
$(".slide", this).stop().animate({right:'-205px'},{queue:false,duration:400}); //Position on rollout
});
Any suggestions would be much appreciated.
Hello - We are stumped and looking for advice..
Were running:
jdk1.6.0_20 , jboss-5.1.0.GA, messaging-2.0.0.BETA4
And trying to add a Topic or Queue but we are getting this error:
Failed to add Resource: java.lang.IllegalStateException:Failed to find template for: TopicTemplate
any advice?
i have 4 processes:
p1 - bursts 5, priority: 3
p2 - bursts 8, priority: 2
p3 - bursts 12, priority: 2
p4 - bursts 6, priority: 1
Assuming that all processes arrive at the scheduler at the same time what is the average response time and average turnaround time?
For FCFS is it ok to have them in the order p1, p2, p3, p4 in the execution queue?
Why this delay of Jquery animation does not work as it should be?
$(" .inner").stop().delay(1000).animate({height:'142px'},{queue:false, duration:600});
Is there any other way to delay this animation?
When calling rdma_disconnect(), do I get completion queue events for all posted recv work requests before rdma_disconnect() returns, or should I expect them to come in after rdma_disconnect() has returned?
Is it possible to start an AMQP subscriber with my Rails app? Possibly through an initializer or something.
I'd like to have it running at the same time that can also interact with Rails models. Below is a pseudo-code example of what I mean.
queue.subscribe do |msg,body|
Foo.create(....)
end
I get this error
All the emails are in a queue

What kind of Kernel error can cause the cpu to go into a shut down state? I'm doing a homework assignment in OS, and we did changes in sched.c (adding a new scheduling policy, which involved ading another prio_array to the queue and switching between them when needed). Processes using this policy cause the cpu to enter a shut down state when they finish. Any suggestions where to look?
What's the best way to configure the maximum number of threads that can pull messages from an MSMQ queue, using a netMsmqBinding in WCF?
For example, say I have an MSMQ service for which I only want to have 2 (or 10, or whatever number of) worker threads pulling messages off at a time.
I want to know why we always use Sorting algorithm like (Insertion Sort or Merge Sort,...) just for lists and arrays? And why we do not use these algorithms for stack or queue?
I write a python class which makes asynchronous method calls using D-Bus. When my reply_handler is called, it stores data in list. This list can be used by another class methods at the same time. Is it safe or I can use only synchronized data structures like Queue class?
Using Scala 2.8 RC1 or newer, what is the best (easiest and/or most direct) method to "peek" at the waiting messages in an actor's mailbox (from within the same actor's act() method) in order to examine what is in the queue, without having to react/receive the messages and/or disturb the current contents of the mailbox in any way.
The purpose of this is so that an actor may determine if it is safe to process a request to exit by first determining if any of the remaining mailbox messages are ones that must be processed, instead of just dropped by stopping the actor immediately.
I want to have class that can be instantiated with list, array, seq, set, stack, queue etc.
In my opinion
class A
class B(elems:A*)
should handle such stuff.
This is my solution:
class A
class B(elems:Iterable[A]){
def this(elem:A) = this(Seq(elem))
}
Can you suggest any improvements?
Hello,
I have a CSV file which is about 1GB big and contains about 50million rows of data, I am wondering is it better to keep it as a CSV file or store it as some form of a database. I don't know a great deal about MySQL to argue for why I should use it or another database framework over just keeping it as a CSV file. I am basically doing a Breadth-First Search with this dataset, so once I get the initial "seed" set the 50million I use this as the first values in my queue.
Thanks,
Hi everybody,
Having some trouble sending properly formatted HTML e-mail from a PHP script. I am running PHP 5.3.0 and Apache 2.2.11 on Windows XP Professional.
The output looks like this:
Agent Summary for Support on Tuesday April 20 2010=20
Ext. Name Time Volume
137 Agent Name 01:27:25 1
138 =09 00:00:00 0
139 =09 00:00:00 0
You see the =20 and =09 in there? If you look at the HTML you also see = signs being turned into =3D. I figure this is a character encoding issue as I read the following at Wikipedia:
ISO-8859-1 and Windows-1252 confusion
It is very common to mislabel text data with the charset label ISO-8859-1, even though the data is really Windows-1252 encoded. In Windows-1252, codes between 0x80 and 0x9F are used for letters and punctuation, whereas they are control codes in ISO-8859-1. Many web browsers and e-mail clients will interpret ISO-8859-1 control codes as Windows-1252 characters in order to accommodate such mislabeling but it is not standard behaviour and care should be taken to avoid generating these characters in ISO-8859-1 labeled content.
This looks like the problem but I don't know how to fix. My code looks like this:
ob_start();
report_queue_summary($yesterday,$yesterday,$first_extension,$last_extension,$queue);
$body_report = ob_get_contents();
ob_end_clean();
$body_footer = "This is an automatically generated e-mail.";
$message = new Mail_mime();
$html = $body_header.$body_report.$body_footer;
$message->setHTMLBody($html);
$body = $message->get();
$extraheaders = array("From"=>"***redacted***","To"=>$recipient, "Subject"=>"Agent Summary for $yesterday [$queue]", "Content-type"=>"text/html; charset=iso-8859-1");
$headers = $message->headers($extraheaders);
# setup e-mail;
$host = "*********";
$port = "26";
$username = "*****";
$password = "*****";
# Send e-mail
$smtp = Mail::factory('smtp',
array ('host' => $host,
'port' => $port,
'auth' => true,
'username' => $username,
'password' => $password));
$mail = $smtp->send($recipient, $extraheaders, $body);
if (PEAR::isError($mail)) {
echo("" . $mail->getMessage() . "");
} else {
echo("Message successfully sent!");
}
Is the problem that I'm using output buffering?
Different STL containers like vector, stack, set, queue, etc support different access methods on them.
If you are coding for example in Notepad++ or vim, you have to continuously refer to the documentation to see what all methods are available, atleast I have to.
Is there some good way of remembering which container supports which methods??
Is it possible to limit the number of JMS receiver instances to a single instance? I.e. only process a single message from a queue at any one time?
The reason I ask is because I have a fairly intensive render type process to run for each message (potentially many thousands). I'd like to limit the execution of this code to a single instance at a time.
My application server is JBoss AS 6.0
Any help much appreciated
I'm looking for implementations of lock-free containers:
Blocking Queue
Blocking Stack
Hash Map
etc...
Are there any good libraries out there? I would like to refrain from writing these data structures... I would much rather use something that has been tested by the community.
I have a python script that'll be checking a queue and performing an action on each item:
# checkqueue.py
while True:
check_queue()
do_something()
How do I write a bash script that will check if it's running, and if not, start it. Roughly the following pseudo code (or maybe it should do something like ps | grep?):
# keepalivescript.sh
if processidfile exists:
if processid is running:
exit, all ok
run checkqueue.py
write processid to processidfile
I'll call that from a crontab:
# crontab
*/5 * * * * /path/to/keepalivescript.sh
Thanks in advance.
I've got a number of tasks/servlets that are hitting the HardDeadlineExceededError which is leaving everything hanging in an 'still executing' state.
The work being done can easily exceed the 29 second threshold.
I try to catch the DeadlineExceededException and base Exception in order to save the exit
state but neither of these exception handlers are being caught...
Is there a way to determine which tasks are in the queue or currently executing?
Are there any other strategies for dealing with this situation?
Hi
How do I use mqueue (message queue) in a c program on a Linux based system?
I'm looking for some good code examples that can show how this is done in a correct and proper way, maybe a howto.
Thanks
