  • How does Appcelerator Titanium Mobile Work?

    - by Darrell Brogdon
    I'm working on building an iPhone app with Titanium Mobile 1.0 and I see that it compiles down to a native iPhone binary. How does this work? Seems like it would take a lot of heavy lifting to analyze the JavaScript code and do a direct translation into Objective-C without having a subset language like 280 North's Objective-J and Cappuccino.

  • Trouble with inheritance

    - by Matt
    I'm relatively new to programming so excuse me if I get some terms wrong (I've learned the concepts, I just haven't actually used most of them). Trouble: I currently have a class I'll call Bob its parent class is Cody, Cody has method call Foo(). I want Bob to have the Foo() method as well, except with a few extra lines of code. I've attempted to do Foo() : base(), however that doesn't seem to work like. Is there some simple solution to this?

  • What does "prototyping" mean in practice?

    - by prot
    When I recently asked about the uses of Ruby someone told me it was good for prototyping. I basically know what that means, quickly get the very base of your app up and working, see if there are conceptual problems and then add the rest. Am I right with how I understand prototyping? What would be a concrete example of prototyping a Snake game in Ruby or any other language?

  • Video Game Bots?

    - by cam
    Something I've always wondered, especially since it inspired me to start programming when I was a kid, was how video game bots work? I'm sure there are a lot of different methods, but what about automation for MMORPGs? Or even FPS-type bots?

  • Differnce between linux write and sendfile syscall

    - by JosiP
    Hi Im programming webserver (C), which should send big files. My question is: What are the main differneces in two syscalls: write and sendfile. Does sendfile depends on size of socket system buffer ? I noticed that write often writes less then i requested. For example, if got many requests for one file: should i open it, copy into memory and use 'write', or maybe i can do 'sendfile' for each client ? thx in advance for all answers

  • Ruby Mobile Ports

    - by Nathan Campos
    I'm now learning Ruby because I saw it's a very powerfull language, but now I want to know what mobile ports of Ruby we have and for what devices. PS: I have a HTC S711, HP iPAQ Hx2, Nokia E61, Nokia N95, Palm T|X, Palm Z22, HP Jornada 720..., it's better if I can use it on these platforms, but I'm open to buy other devices, as I'm a mobile addict.

  • Parallel port recording to file on Win XP

    - by Nikola Kotur
    Hi there. I need to write a simple program that records all the input from parallel port into a file. Data flows from industrial machine, setup is fairly simple, but I can't find any good open source examples on parallel port reading for Windows. Do you know a software that does this (and lets me learn how to do it myself), or is there any guideline for parallel port programming on XP? Thanks.

  • How to use prettify with blogger/blogspot?

    - by billpg
    Hi everyone. I'm using blogger.com to host some texts on programming, and I'd like to use prettify (same as stackoverflow) to nicely colour the code samples. How do I install the prettify scripts into the blog domain? Would it be better (if indeed its possible) to link to a shared copy somewhere? I have webspace on a different domain. Would that help? Many thanks.

    - by Tim Lytle
    Does anyone know of an app that can monitor a beanstalkd queue? I'm looking for something that shows stats on tubes and jobs, and allows you to inspect the details. I'm not really picky about language/platform, just want to know if there's something out there before I write my own.

  • What freeware/floss tools are available to help load data into SPSS?

    - by tardate
    I'm looking for a solution for producing SPSS format data files for loading into SPSS. The few offerings I can find are all commercial. Has anyone experience with generating SPSS-format data files using open-source, freeware or home-grown solutions? I'm not even sure that the file format is "open". Any hints appreciated (any language is fine, although java, perl or ruby preferred).

  • Fluent API Style Usage

    - by Chris Dwyer
    When programming against a fluent API, I've seen the style mostly like this: var obj = objectFactory.CreateObject() .SetObjectParameter(paramName, value) .SetObjectParameter(paramName, value) .DoSomeTransformation(); What is the reasoning behind putting the dot at the beginning of the line instead of the end of the line like this: var obj = objectFactory.CreateObject(). SetObjectParameter(paramName, value). SetObjectParameter(paramName, value). DoSomeTransformation(); Or, is it merely a style thing that a team makes a consensus on?
