• using qsub (sge) with multi-threaded applications

  - by dan12345

  i wanted to submit a multi-threaded job to the cluster network i'm working with - but the man page about qsub is not clear how this is done - By default i guess it just sends it as a normal job regardless of the multi-threading - but this might cause problems, i.e. sending many multi-threaded jobs to the same computer, slowing things down. Does anyone know how to accomplish this? thanks. The batch server system is sge.

• How do I set selection to Nothing when programming Excel using VBA?

  - by Curt

  When I create a graph after using range.copy and range.paste it leaves the paste range selected, and then when I create a graph a few lines later, it uses the selection as the first series in the plot. I can delete the series, but is there a more elegant way to do this? I tried Set selection = nothing but it won't let me set selection. I also tried selection.clear, but that just cleared the last cells that were selected, and still added an extra series to the plot. Curt

• is there a comprehensive example or tutorial for ibatis 3 with annotations?

  - by nn2010

  I am specifically interested in moving away from XML-based mapper configuration to using pure Java annotations where the SQL statements often take or return complex data structures. Also, it wasn't clear in the samples I saw, how the configuration file was adapted when moving away from XML-based mappers to annotation-based Mapper interfaces.

• Is this BlockingQueue susceptible to deadlock?

  - by unforgiven3

  I've been using this code as a queue that blocks on Dequeue() until an element is enqueued. I've used this code for a few years now in several projects, all with no issues... until now. I'm seeing a deadlock in some code I'm writing now, and in investigating the problem, my 'eye of suspicion' has settled on this BlockingQueue<T>. I can't prove it, so I figured I'd ask some people smarter than me to review it for potential issues. Can you guys see anything that might cause a deadlock in this code? public class BlockingQueue<T> { private readonly Queue<T> _queue; private readonly ManualResetEvent _event; /// <summary> /// Constructor /// </summary> public BlockingQueue() { _queue = new Queue<T>(); _event = new ManualResetEvent(false); } /// <summary> /// Read-only property to get the size of the queue /// </summary> public int Size { get { int count; lock (_queue) { count = _queue.Count; } return count; } } /// <summary> /// Enqueues element on the queue /// </summary> /// <param name="element">Element to enqueue</param> public void Enqueue(T element) { lock (_queue) { _queue.Enqueue(element); _event.Set(); } } /// <summary> /// Dequeues an element from the queue /// </summary> /// <returns>Dequeued element</returns> public T Dequeue() { T element; while (true) { if (Size == 0) { _event.Reset(); _event.WaitOne(); } lock (_queue) { if (_queue.Count == 0) continue; element = _queue.Dequeue(); break; } } return element; } /// <summary> /// Clears the queue /// </summary> public void Clear() { lock (_queue) { _queue.Clear(); } } }

• iPhone UIWebView touch cause Toolbar to appear

  - by BahaiResearch.com

  I am trying to have a UI which is a full screen UIWebView. When the view is touched the tool bar appears. I can do everything but get the touchend event in the UIWebView. I have tried putting a UIColor.Clear'd UIView ontop and catching TouchEnd there and passing it on, but would like a better solution. I understand that we are not supposed to subclass the UIWebView from the docs. Ideas?

• Java Method declaration

  - by user1701604

  I'm trying to declare a method for my program that takes only a 5 digit integer and for each digit of the integer, reads a value from the program and prints it out. I understand this isn't very clear but im having trouble relaying what I mean. I understand it will be some sort of for loop to read each digit of the integer individually until something reaches 5. Something like the charAt() string method but works for digits.

  I have a Python web application consisting of several Python packages. What is the best way of building and deploying this to the servers? Currently I'm deploying the packages with Capistrano, installing the packages into a virtualenv with bash, and configuring the servers with puppet, but I would like to go for a more Python based solution.

  - by user1509593

  Is this a probable security flaw. A user in public (lets say Starbucks) tries to log in to iOS application. He enters user id and password [Password is hidden using xxxxxxxx (not exposed)] and a call comes in or he presses home and the application goes to background. a) Does iOS store an image of current screen b) A malicious hacker with intent takes control of the device. Can he read the password ? Do we have to clear out sensitive information while going to background

• How to insert a SQLite record with a datetime set to 'now' in Android application?

  - by droidguy

  Say, we have a table created as: create table notes (_id integer primary key autoincrement, created_date date) To insert a record, I'd use ContentValues initialValues = new ContentValues(); initialValues.put("date_created", ""); long rowId = mDb.insert(DATABASE_TABLE, null, initialValues); But how to set the date_created column to "now"? To make it clear, the initialValues.put("date_created", "datetime('now')"); Is not the right solution. It just sets the column to "datetime('now')" text.

• Which use cases make temporary JMS queues a better choice than persistent queues?

  - by Stephen Harmon

  When you are designing a JMS application, which use cases make you pick temporary queues over persistent queues? We use temporary queues for response messages. We're having some issues maintaining connections to the temp queues, though, so I am testing persistent response queues, instead. One clear disadvantage of persistent queues is that your application has to "know" about them beforehand. If that's not a big deal, though, are there use cases where temp queues are the obvious choice?
