• Is it safe to draw three separate QImages in three separate QThreads?

  - by yan bellavance

  I have a QMainWindow with three widgets inside that are promoted to a class containing a subclassed QThread. They each draw on a local QImage in their rexpective qthread which is sent with a signal once its drawn and then rendered by calling update (mandlebrot example) from the slot. Is this safe or dangerous? They do not share any data, at least none that I am generating and am wondering what data they could be sharing that is outside of my coding range ie that is generated by Qt automatically.

• Is it safe to use connection.createStatement().executeQuery(String query);?

  - by javanix

  Is it safe to do connection.createStatement().executeQuery(String query);, or should each java.sql.Statement object be created and closed by "hand" on every use, even if the connection is closed in a finally block? If multiple queries are executed in one method by one connection it would use much less code if instantiating and closing each statement wasn't strictly necessary.

• Read -> change -> save. Thread safe.

  - by Pavel Alexeev

  This code should automatically connect players when they enter a game. But the problem is when two users try to connect at the same time - in this case 2nd user can easily overwrite changes made by 1st user ('room_1' variable). How could I make it thread safe? def join(userId): users = memcache.get('room_1') users.append(userId) memcache.set('room_1', users) return users I'm using Google App Engine (python) and going to implement simple game-server for exchanging peers given by Adobe Stratus.

• Is it safe to synchronize java.awt.Container.paint(Graphics g)?

  - by Alison G

  I'm using some 3rd party AWT components in a desktop application. The component's layout is changed within the paint() method, and this causes some very strange behaviour. This appears to be fixed by adding the synchronized keyword to the paint() method, but is this a safe thing to do?

• Can a python view template be made to be 'safe/secure' if I make it user editable?

  - by Blankman

  Say I need to have a templating system where a user can edit it online using an online editor. So they can put if tags, looping tags etc., but ONLY for specific objects that I want to inject into the template. Can this be made to be safe from security issues? i.e. them somehow outputing sql connection string information or scripting things outside of the allowable tags and injected objects.

• Is using project:permissions in a symfony project safe in a production environment?

  - by mhughes

  As the question states, is this task safe for a production environment? I find the permissions rather permissive, the cache directory is the one i find particularly suspicious. Write and execution permission on a code directory is somewhat suspicious. Cheers

• Is it safe to make GL calls with multiple threads?

  - by user146780

  I was wondering if it was safe to make GL calls with multiple threads. Basically I'm using a GLUtesselator and was wondering if I could divide the objects to draw into 4 and assign a thread to each one. I'm just wondering if this would cause trouble since the tesselator uses callback functions. Can 2 threads run the same callback at the same time as long as that callback does not access ant global variables? Are there also other ways I could optimize OpenGL drawing using multithreading? Thanks

• How do I configure AT&T's Uverse 2Wire 2701HGV-B Gateway into DMZPlus Mode?

  - by MasD

  I subscribed for AT&T's Uverse service and they shipped me a Wire 2701HGV-B Router/Gateway/Firewall/WiFi. I would like to configure AT&T's hardware to have less control and use my trusted Linksys WRT54-G router between my computers and the 2Wire Gateway. This seems to be a common configuration for Uverse users with this hardware in other forums, but requires a "DMZPlus" mode that I'm unfamiliar with.

• What is a good program for mixed mode circuit simulation?

  - by Jeff Shattock

  I'm looking for a program that will perform schematic capture and mixed-mode (analog and digital) circuit simulation. If it also did PCB layout and routing, that would be a bonus, but not necessary. I currently use an old version of CircuitMaker/TraxMaker, but its dated, and the simulation engine is a bit lacking. Windows or Linux, doesn't really matter. What is a good program for this purpose?

• Is it possible to run vim in remote mode on another machine?

  - by Leonid Shevtsov

  Hi, I run an Ubuntu server virtualbox under a Windows host for web development. At the moment I do all editing in Vim running inside PuTTY. It runs pretty well, but lacks some useful features like native copypasting from the host. I know about the remote mode of Vim, but afaik it can only operate on the same machine. Question is, is it possible to make gVim on the windows host proxy all the commands (and the editing) to a Vim instance running on the Linux guest?
