• GestureListener's fling method doesn't get called

  - by nosferat

  I'm using SimpleGestureDetector from the libgdx-users Wiki as my InputProcessor. I set it in the created() method: Gdx.input.setInputProcess(new SimpleDirectionGestureDetector(charController)); charController is my class which implements the DirectionListener interface defined in the SimpleDirectionGestureDetector class and it is responsible for moving the player character. However the character doesn't change direction when I'm performing a fling action in any direction. I've checked and the fling() method in the SimpleDirectionGesture class doesn't get called and I have no idea why, since everything seems good. What am I doing wrong?

• How i can sign and/or group a specific set of vertices in a 3D file container like OBJ ? - in Blender

  - by user827992

  I would like to export a 3D model with each part having a name or a label if you will. For example i would like to export a model of an human body and name each part in specifics vertex groups like: left hand, right hand, right foot, head, ears, ... and you got the idea; so i can have a single 3D model that i can explode in various parts if needed. If there is a better technique about how to mark vertex groups in a 3D file please share your solution. As 3D editor i use Blender.

• Blockbuster Time Machine

  - by David Dorf

  In another example of clinging to the core business much too long, DISH announced its closing the remaining 300 Blockbuster stores.  This reminds us that we must always be looking over our shoulders for the next big thing.  Blockbuster had the opportunity to buy Netflix, but it passed just as Barnes & Noble decided it didn't need to partner with Amazon.  Its so tempting to stick with a profitable business instead of taking a risk on a new idea.  Nevertheless, Blockbuster is history -- and this video from The Onion seals it. Historic ‘Blockbuster’ Store Offers Glimpse Of How Movies Were Rented In The Past

• Problem with wine

  Recently I've installed StarCraft 2 via playonlinux. The installation was absolutly no problem, everything was fine. But if I want to start the game now, it crashes. If I start it on the Terminal I get following error: optirun /usr/share/playonlinux/playonlinux --run "StarCraft II Wings of Liberty" [POL_Wine_SetVersionEnv] Message: Setting wine version path: 1.3.27, amd64 [POL_Wine_SetVersionEnv] Message: "/home/gernot/.PlayOnLinux//wine/linux-amd64/1.3.27" exists [POL_Wine] Message: Running wine-1.3.27 StarCraft II.exe wine: cannot find L"C:\windows\system32\winemenubuilder.exe" rm: Cannot remove »*“ : Can't find directory or file.

• Unity-2D ALT F1,F2 custom configuration

  - by LGB

  I have been using Ubuntu since the first public version (I used Debian before). I always have had the policy to change between 8 workspaces with ALT F1...F8. I know this is not a "standard" or so, but I prefer this. It worked well with Unity (Unity-2D, I mean) too, after some configuration. But currently the odd thing happened that after a system restart this is not the case anymore, I am totally lost what could happened. Now ALT F3...F8 works, but not ALT-F1...F2, which just focuses launcher/dash, which is not the thing I want. I know this is the standard meaning of these key combinations (AFAIK) but defining my own key combinations worked before and now it stopped working ... If someone have any idea how to restore my custom configured meaning for ALT F1...F2 too, please share with me. Thanks!

• How does a government development shop transition to developing open source solutions?

  - by Rob Oesch

  Our shop has identified several reasons why releasing our software solutions to the open source community would be a good idea. However, there are several reasons from a business stand point why converting our shop to open source would be questioned. I need help from anyone out there who has gone through this transition, or is in the process. Specifically a government entity. About our shop: - We develop and support web and client applications for the local law enforcement community. - We are NOT a private company, rather a public sector entity Some questions that tend to come about when we have this discussion are: We're a government agency, so isn't our code already public? How do we protect ourselves from being 'hacked' if someone looks into our code? (There are obvious answers to this question like making sure you don't hard code passwords, etc. However, the discussion needs to consider an audience of executives who are very security conscience.)

• Code review vs pair programming

  - by mericano1

  I was wondering what is the general idea about code review and pair programming. I do have my own opinion but I'd like to hear from somebody else as well. Here are a few questions, please give me your opinion even on some of the point First of all are you aware of way to measure the effectiveness of this practices? Do you think that if you pair program, code reviews are not necessary or it's still good to have them both? Do you think anybody can do code review or maybe is better done by seniors only? In terms of productivity do you think it suffers from pairing all the times or you will eventually get in back in the long run? Thanks!

• How do you maintain content size vs. content quality in an application?

  - by PeterK

  I am developing my first Cocos2d iPhone/iPad game that includes quite a few sprites, I would need approximately 80 different. As this is for both normal and HD displays I have 2x of each sprite. I am using TexturePacker to optimize the thing. I would like to ask if there are any rules-of-thumb, tricks, ideas etc. to adjust to in regards to size of content, quality and how you maintain high-quality HD-based graphics due to its size vs. the device memory sizes? Also, is it a good idea to only have one copy of the sprites and scale it using code?

• aticonfig detects all graphics cards, but amdcccle shows the cards as disabled

  - by DevZer0

  I been having the strangest problem since few days ago. I have 3 ATI graphics cards and the aticonfig --list-adapter shows the following output * 0. 01:00.0 AMD Radeon HD 7900 Series 1. 02:00.0 AMD Radeon HD 7900 Series 2. 05:00.0 AMD Radeon HD 7900 Series when i do aticonfig --adapter=all --initial -f it generates the correct X config also. but after rebooting the output only show on primary monitor and when i look in amdcccle it shows the other 2 adapters as disabled. I tried with monitors attached and dummy plugs both but the situation doesn't change. Any idea whats causing this? also right clicking and making the adapter enabled in amdcccle and saving changes causes the X config to only have the adapter section and no screen section. after reboot the situation stays the same.

• Microsoft Access 2010: How to Add, Edit, and Delete Data in Tables

  Tables are such an integral part of databases and corresponding tasks in Access 2010 because they act as the centers that hold all the data. They may be basic in format, but their role is undeniably important. So, to get you up to speed on working with tables, let's begin adding, editing, and deleting data. These are very standard tasks that you will need to employ from time to time, so it is a good idea to start learning how to execute them now. As is sometimes the case with our tutorials, we will be working with a specific sample. To learn the tasks, read over the tutorial and then apply...

I uninstalled and reinstalled it, it worked once but failed after restart. Has anyone an idea what might be the problem here? Thanks in advance. Regards

• SEO Question - allintitle with or without quotes

  - by Aaron

  I'm trying to learn more about implementing basic SEO strategies and have been spending a lot of time refining my keywords using Google Analytics combined with manually checking them using Google's allintitle operator. However, I'm unclear on whether I should be using quotes with my allintitles. Example: allintitle: seo tips and tricks for beginners 191 results allintitle: "seo tips and tricks for beginners" 70 results My thought is that it would be more accurate to use it without quotes because that way you get a more well rounded idea of all those you are competing with. So, my question is does Google give more weight to exact matches in the title tag or does that not really matter? If someone searched for: seo tips and tricks for beginners, would they be more likely to see the ones that have that exact phrase in their title tag or does that not have any impact?

• Which language to learn C# or Salesforce.com/apex for C++ programmer [closed]

  - by polapts

  Being a C++ programmer with 7-8 years of experience, I wanted to know the market trends. When I searched a little bit I found more jobs with keyword C# than C++ or Java. I am just wondering if it is a good idea to learn C# or Java from a career perspective. Also, I read somewhere about Salesforce/apex. It was mentioned that this is something in vogue. So my question is which technology I should go for C#/Java/Salesforce(Apex) from career perspective? Thanks

• Cannot get Atheros AR9285 to work on 12.10

• Optimization of a Hybrid Pagination Scheme

  - by Kaustubh Karkare

  I'm working on a Web Application using node.js in which I'm building a partial copy of the database on the client-side to decrease the load on my server. Right now, I have a function like this (expressed as python-style pseudocode, but implemented in JavaScript): get(table_name,primary_key): if primary_key in cache[table_name]: return cache[table_name][primary_key] else: x = get_data_from_server(table_name,primary_key) # socket.io return cache[table_name][primary_key] = x While this scheme works perfectly well for caching individual rows, I'd like to extend it to support the creation of paginated tables ordered according to the primary_key, and loading additional data using the above function for only the current and possibly the adjacent pages. Now, I don't want to keep the list of primary keys on the server to be retrieved every time I need to change the page (which, for reasons beyond the scope here, will be very frequent), and keeping it on the client side, subject to real-time create/delete events from the server, doesn't seem that good an idea, even after compression (using ranges, instead of individual values). What is the best way to calculate which items are to be displayed on a random page, minimizing the space requirements & the need for communication with the server?

• How can be data oriented programming applied for GUI system?

  - by Miro

  I've just learned basics of Data oriented programming design, but I'm not very familiar with that yet. I've also read Pitfalls of Object Oriented Programming GCAP 09. It seems that data oriented programming is much better idea for games, than OOP. I'm just creating my own GUI system and it's completely OOP. I'm thinking if is data oriented programming design applicable for structured things like GUI. The main problem I see is that every type widget has different data, so I can hardly group them into arrays. Also every type of widget renders differently so I still need to call virtual functions.

• How can I make a collection of mini-games in XNA where the user can download packs of minigames and the main .exe can run them without being altered?

  - by Pyroka

  I'm currently making a PC game in XNA. It's actually a collection of mini-games (there's 3 mini-games at the moment) however I plan to make and add more, in downloadable 'packs'. My question is, what's the best way to achieve this? Currently my thoughts are: Create a 'game' interface Build games to this interface but create them as .dlls Have the main .exe file scan a directory and load in the .dlls at runtime. I've not messed around with the idea much, but I know there are applications at-least that use this plug-in approach (Notepad++ seems to), but I'm not sure of any games that do (although I'm sure they must exist). However it seems that this is a problem that has been solved previously, so I'm wondering if there's any form of established best-practice.

• Seizing The Moment With Mobility

  - by Scott Ewart

  Mobile devices are forcing a paradigm shift in the workplace – they’re changing the way businesses can do business and the type of cultures they can nurture. As our customers talk about their mobile needs, we hear them saying they want instant-on access to enterprise data so workers can be more effective at their jobs anywhere, anytime. They also are interested in being more cost effective from an IT point of view. The mobile revolution – with the idea of BYOD (bring your own device) – has added an interesting dynamic because previously IT was driving the employee device strategy and ecosystem. That's been turned on its head with the consumerization of IT. Now employees are figuring out how to use their personal devices for work purposes and IT has to figure out how to adapt.

• What standard superseded 830-1998?

  - by user1564158

  I have been looking into how to document software projects more formally, and I have learned about IEEE 830-1998: Recommended Practice for Software Requirements Specifications. However, as you can see from that link, it has been superseded. I know that 830-1998, and probably even 830-1993, are probably just fine for use. However, if nothing else, I would like to know what standard has superseded it. In this case it may not matter, but if other standards are superseded for more technical things, I think it would be a good idea to link somewhere what standard superseded another (if it is not another one in the same line (830, in this case)). It is worth mentioning that: The most recent standard when searching for "Software Requirements Specifications" or "Software Requirements" on the IEEE Standards Association website is 830-1993, The 2004 (current) version of SWEBOK references 830-1993 (paragraph 2.5), The document's Wikipedia article doesn't mention that the standard was superseded. TLDR: How do you find what standard superseded another, and which one took 830-1998's place?

• Why do I get the message "program not found" when running "mal" for Latex

  - by maclin

  just started using Ubuntu (11.10 oneiric). It is running on a virtual machine. I used to use SuSE. However, SuSE is now with Novel, which goes hand in hand with Microsoft. So now shifted to Ubuntu. For documentation I use LaTeX and installed a package. This package uses a pre-processer (it is called "mal"). I ran the textconfig rehash command as required, but when I try to run the program, I get a "program not found" error. I am guessing that it is not in my path. (a sudo did not help) Any idea?

• Open .doc file from my website in browser

  - by seth

  What's the best way to give the end-user of my web application the ability to open, edit and save (via browser) word documents that are stored in my database? I have this working by doing an html conversion of the file (via Aspose Words) but this method seems not even close to flawless and i'm trying to improve this. Is integrating with google docs possible/good? Their edition seems awesome and very powerful. I can't use any Microsoft Word objects (and this is even discouraged by MS). EDIT: The application is developed in .NET and currently uses the .NET framework 2.0. However, as this is fairly obsolete the idea is to restart from scratch and therefore use the 4.0 framework and C# or VB.

• How to study for an Informatics Olympiad [on hold]

  - by Cloud

  One of my goals for next year is to participate in the Australian Informatics Olympiad. As far as I'm aware, it is not too different from Informatics Olympiads in other countries. What would be the best way to study for this? What content should I pay particular attention to while learning in Python? I am currently using the book 'Learn Python the hard way', but are there any other books worthy of a mention? This is the link to their site: http://orac.amt.edu.au/aio/ It contains sample questions, so you can get an idea for the structure or nature of the competition. I know this isn't really a specific programming question, but it would be great if someone could share their experience or give some suggestions for me.

• How do you assign commands to keys in Terminal?

  - by NES

  Is there a solution to assign special key combinations to words in terminal use. For example the less command is very usefull and i use i a lot to pipe the output of another process through it. The idea would be to set up special key combinations that are only active in terminal use assigned to write different commands? So pressing CTRL + l in terminal window could write | less or CTRL + G could stand for | grep Note: i just mean adding the letters to commandline not execute the finally. A similar way what's tabcompletion but more specific.
