    - by Zignd
    After installing Lubuntu 12.10, I decided to install IDLE 3 (from the official Ubuntu repository), but something unexpected happened, its icon gets bigger then the LxPanel and all the another aplications icos, the same happens at the menu when I select it from Menu Programming IDLE 3 Check the image: Note: Wasn't possible to take a printscreen from IDLE at the Menu because the printscreen action ignore the menu when it is opened.

  • Performance Tune IBM DB2 z/OS Applications using Resource Constraint Analysis

    For the DB2 for z/OS professional the two most common systems tuning scenarios are tuning a DB2 data sharing group or tuning a series of application SQL statements. The data sharing group environment can involve multiple hardware installations and many other cross-system features and functions such as coupling facilities and management policies. Resource constraint analysis is a useful tool in both situations.

  • Dual Monitor Lock Screen Problem

    - by Justin Carver
    Ubuntu 12.04 Nvidia GTX 550-Ti x-swat Nvidia driver Problem: Using 2 monitors. When screen locks there is a blue box on top of the wallpaper and password dialog box that hides the field for entering your password or switching users. Problem is on 2 systems with similar hardware (Nvidia card, x-swat driver, dual monitors) You can still type your password in blindly and hit enter to login but it's irritating to not be able to see the dialog box.

I wish to implement a plugin which, if enabled by the user, to read content on my website. Presumably my best option is a website plugin, however there might be some programming I've not come across which allows the likes of PHP to read content. I'm not entirely sure how this all works.

  • Keeping local folders synchronized

    - by Earthling
    After repeatedly losing data on encrypted drives due to some trivial combination of software and hardware failure, I would like to know if there is a simple tool that keeps local folders synchronized. Like a local "cloud" service that runs on one computer and synchronizes any changes in one folder to the other folder as soon as both folders are available. That way I can keep a copy of the most important files on a different hard-drive.

  • When creating a library for a simple program, what must I do to protect others from its lack of thread safety?

    - by DeveloperDon
    When creating a library for a simple program, is it more cost effective to make it thread safe or is there a way to detect the program's use in a multithreaded program and ASSERT() or otherwise determine (preferably at compile or link time) that it may create problems. Related help for this question would be automated tool support for finding potential problems with thread safety, programming language features that enforce it,

  • Pre-rendered fire. Where to find? [on hold]

    - by Vladivarius
    I'm studying game programming. I haven't yet implemented generated fire rendering in my ,,engine'' so I'm looking for some pre-rendered fire textures for early demo-scenes, but they seems strangely difficult to find. I'm currently using some that I ripped from DMC but I want to try out different ones. Does anyone know where to find these? Software that could generate them would also be ok. Thanks :)

  • Why C++ people loves multithreading when it comes to performances?

    - by user1849534
    I have a question, it's about why programmers seems to love concurrency and multi-threaded programs in general. I'm considering 2 main approach here: an async approach basically based on signals, or just an async approach as called by many papers and languages like the new C# 5.0 for example, and a "companion thread" that maanges the policy of your pipeline a concurrent approach or multi-threading approach I will just say that I'm thinking about the hardware here and the worst case scenario, and I have tested this 2 paradigms myself, the async paradigm is a winner at the point that I don't get why people 90% of the time talk about concurrency when they wont to speed up things or make a good use of their resources. I have tested multi-threaded programs and async program on an old machine with an Intel quad-core that doesn't offer a memory controller inside the CPU, the memory is managed entirely by the motherboard, well in this case performances are horrible with a multi-threaded application, even a relatively low number of threads like 3-4-5 can be a problem, the application is unresponsive and is just slow and unpleasant. A good async approach is, on the other hand, probably not faster but it's not worst either, my application just waits for the result and doesn't hangs, it's responsive and there is a much better scaling going on. I have also discovered that a context change in the threading world it's not that cheap in real world scenario, it's infact quite expensive especially when you have more than 2 threads that need to cycle and swap among each other to be computed. On modern CPUs the situation it's not really that different, the memory controller it's integrated but my point is that an x86 CPUs is basically a serial machine and the memory controller works the same way as with the old machine with an external memory controller on the motherboard. The context switch is still a relevant cost in my application and the fact that the memory controller it's integrated or that the newer CPU have more than 2 core it's not bargain for me. For what i have experienced the concurrent approach is good in theory but not that good in practice, with the memory model imposed by the hardware, it's hard to make a good use of this paradigm, also it introduces a lot of issues ranging from the use of my data structures to the join of multiple threads. Also both paradigms do not offer any security abut when the task or the job will be done in a certain point in time, making them really similar from a functional point of view. According to the X86 memory model, why the majority of people suggest to use concurrency with C++ and not just an async aproach ? Also why not considering the worst case scenario of a computer where the context switch is probably more expensive than the computation itself ?

  • Unable to install applications (Oneiric)

    - by yayu
    When I use the software center to install something, I get the error: An unhandlable error occured There seems to be a programming error in aptdaemon, the software that allows you to install/remove software and to perform other package management related tasks on using the command line: $sudo apt-get install <something> E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. I am unable to install anything. How do we fix this?

  • Should I run Ubuntu 64bit on a laptop with 2GB of RAM?

    - by nhanb
    I'm using an Asus K43E laptop with: - Intel Core i3 Sandy Bridge 2.1GHz - 2GB DDR3 - Onboard graphics On the Ubuntu download page, the 32bit version is marked as "recommended", but the community documentation page suggests otherwise: Unless you have specific reasons to choose 32-bit, we recommend 64-bit to utilise the full capacity of your hardware. I use my laptop mostly for Eclipse, apart from regular office applications, then does it make any difference when choosing between 32bit and 64bit?

  • What should a Python developer know while learning Ruby?

    - by C J
    I have been a Python programmer for about 18 months, consisting of one internship and a few side projects, and I consider myself pretty comfortable in the language. However, there seems to be a lot of attention on Ruby in the programming field, but not a lot on Python anymore. So in learning Ruby, are there going to be Pythonic things that are just bad practices in Ruby? What should I watch out for, and what should I avoid?

  • Where is the time spent?

    - by 280Z28
    Game development is a large process. In your experience, how are the total hours for releasing a game divided over the following major areas. I believe this is useful because few people (none?) are really good at all the areas, so this helps me balance the cost of items I'm not so good at when estimating the complexity of creating a game. Modeling and raw asset creation (textures, audio) Level design Gameplay design Programming Testing Marketing
