• Ubuntu 12.04 upgrade (from 11.10) removed all packages installed

  - by Jagmal

  I upgraded from Ubuntu 11.10 to 12.04 using bootable USB. After upgrade, all non-default packages from 11.10 are gone. For ex, I did not have Chromium, Eclipse etc. Although, I could see these in the History in the "Ubuntu Software Center". Is there any way I can retrieve all these packages (even reverting back to 11.10 is also fine with me)? What could be a possible reason for this (We plan to upgrade a few more machines)? During the upgrade process, I had unchecked the box which asked permission to look online for upgrade/packages. Co

• Audio programming resources

  - by rashleighp

  I've been very interested in the last few months about getting in to audio programming (I'm from a musical background). I've been a .NET developer for two years and have also done some objective c for an iPhone app recently. I realise I would probably need to work on my C++ chops and have been having a play around with FMOD EX and doing a lot of research into the industry. I was just wondering if anyone could suggest some good resources for audio programming (be they websites, podcasts, books, videos, online courses etc). Anything from Fourier analysis, low level coding, audio engine creation to audio APIs. I just want to learn as much as possible! Thanks in advance.

• Attributes and Behaviours in game object design

  - by Brukwa

  Recently I have read interesting slides about game object design written by Marcin Chady Theory and Practice of the Game Object Component Architecture. I have prototyped quick sample that utilize all Attributes\Behaviour idea with some sample data. Now I have faced a little problem when I added a RenderingSystem to my prototype application. I have created an object with RenderBehaviour which listens for messages (OnMessage function) like MovedObject in order to mark them as invalid and in OnUpdate pass I am inserting a new renderable object to rederer queue. I have noticed that rendering updates should be the last thing made in single frame and this causes RenderBehaviour to depend on any other Behaviour that changes object position (i.ex. PhysicsSystem and PhysicsBehaviour). I am not even sure if I am doing this the way it should be. Do you have any clues that might put me on the right track?

• Would there be any reason not to use github (or any open source hosting site) for my code?

  - by Jetti

  So I just created my first github repo and started to wonder if there would be any reason why somebody shouldn't post their code. I don't mean the obvious, such as code that is IP of somebody else or any other possible legal situation; I'm talking about a newbie posting their own, albeit terrible, code. I've heard several times on this site that one of the things that a some of the hiring managers do is check out the person on Github (or similar site), so what if the code is lacking? Would the position desired matter? (ex Junior Developer vs Senior)?

• How to report abuse to website hosting company (GoDaddy)

  - by lgratian

  I'm not sure if this is the right place to ask such a question... Let's say that a website posted a picture of me, without my consent, and I want to be removed (it's something private, could compromise my career if it's seen by someone that shouldn't). I sent them an email asking nicely that they should remove it, but they didn't respond and the picture is still there. Using 'Whois' I found that the website is hosted by GoDaddy. Is there a way (an email address, for ex.) to report to GoDaddy that one of the sites they're hosting does something illegal and to force them to remove the photo? I searched the site and found nothing about such a thing. Thnaks in advance!

• What's the most productive coding environment

  - by Ubiguchi

  I was speaking with an ex-colleague the other day about the most productive way to write code and he said he found it best "to CIMP, or Code In My Pants". When I asked him exactly what he meant, he explained he found it best to work at home, coding at his own pace, dressed comfortably (in his pants), and communicating with his team through emails, IM, or the telephone. Digesting his approach (which he describes to clients as the Complete Integrated Method of Programming), I realised my coding is also more productive when working in an isolated environment, which made me wonder if the software industry has got it all wrong and should development be really done by dispersed teams of individuals, or are there advantages to geographical herding that make up for the added interruptions it brings? So has business got it wrong? Should development occur predominantly across geographically isolated individuals to increase productivity, or are there real reasons why herding developers together makes sense?

• Is it possible to modify a video codec + distribute it?

  - by Nick

  this is my first question on this particular stackexchange node, not sure if it's the most appropriate place for this question (if not, guidance to the appropriate node would be appreciated). the abstract: I'm interested in modifying existing video codecs and distributing my modded codecs in such a way as to make them easily added to a users codec library... for example to be added to their mpeg streamclip, ffmpeg etc. some details: I've had some experience modifying codecs by hacking ffmpeg source files and compiling my hacked code (so that for ex: my version of ffmpeg has a very different h.263 than yours). I'm interested now in taking these modified codecs and somehow making them easily distributable, so others could "add them" to their "libraries." Also, I realize there are some tricky rights/patent issues here, this is in part my motivation. I'm interested in the patent quagmires, and welcome any thoughts on this as well. ctx link: if it helps (to gauge where I'm coming from) here's a link to a previous codec-hacking project of mine http://nickbriz.com/glitchcodectutorial/

• Vertex data split into separate buffers or one one structure?

  - by kiba2

  Is it better to have all vertex data in one structure like this: class MyVertex { int x,y,z; int u,v; int normalx, normaly, normalz; } Or to have each component (location, normal, texture coordinates) in separate arrays/buffers? To me it always seemed logical to keep the data grouped together in one structure because they'd always be the same for each instance of a shared vertex and that seems to be true for things like character models (ex: the normal should be an average of adjacent normals for smooth lighting). One instance where this doesn't seem to work is other kinds of meshes like say a cube where the texture coordinates for each may be the same but that causes them to be different where the vertices are shared. Does everybody normally keep them separate? Won't this make them less space efficient if there needs to be an instance of texture coordinates and normals for each triangle vertex (They won't be indexed)? Can OpenGL even handle this mixing of indexed (for location) vs non-indexed buffers in the same VBO?

• Triple Monitor Setup with Nvidia and Compiz

  - by AndrewX192

  I have a triple monitor setup with two video cards on Ubuntu 10.04. I have the monitors and graphics cards currently setup as follows: Nvidia Geforce 210 #1 - 1920x1080 Monitor (Twinview) [Center - Monitor #1] - 1920x1080 Monitor (Twinview) [Right - Monitor #2] Nvidia Geforce 210 #2 - 1920x1080 Monitor (Separate X Screen) [Left - Monitor #3] This works fine, except when I open a program, it shows up in between monitor #1 and #2 - meaning I have to drag it to one screen before I can use the window. Gnome2's gnome-panel also does not work on the twinview setup; it spans between both monitors, but it does not redraw (ex: the clock never changes). In addition, when I maximize an application, it spans both monitors, which is not acceptable. When I enable Xinerama for my setup, gnome-panel no longer spans two monitors, and applications maximize as expected, but compiz does not work, as X11 compositing is not available. The lack of desktop compositing causes problems with dragging windows between screens (redraws take forever). Is there anything I can do to fix these issues without opting for different graphics cards?

• How to find classes that use certain DB tables

  - by Songo

  Problem: I'm asked to prepare a document where all our DB tables are listed and I'm supposed to list all Controllers that uses these DB tables for read and another list for Controllers that do write operations. Ex: +------------------------------------------+------------+ | DB table | tbl_Orders | +------------------------------------------+------------+ |Controllers that perform read operations | ?? | +------------------------------------------+------------+ |Controllers that perform write operations | ?? | +------------------------------------------+------------+ We are trying to write some documentation for a legacy system built using Zend framework. The code is scattered everywhere. There is code in the Controllers, in the models and even in the views. The application uses PROPEL as an ORM. What makes this really difficult is that the Controller may not be directly calling the table, but it may be instantiating a model class that calls that table. Is there an educated way to approach this crazy task? Note: Searching for the table name won't provide a solution because if a model uses that table I wouldn't know which Controller is using that model.

• arrays format (Javascript)

  - by João Melo

  i have a list of users, with minions, something like this: User52: minion10 minion12 User32: minion13 minion11 i've been keeping in an array where the "location" is the id, like this: Users: [52]User minions: [10]minion [12]minion [32]User minions: [13]minion [11]minion so i can access them easily like this: user[UserID].minions[MinionID] (ex: user[32].minions[11]) but when i print it or send it by json i get something like this: {,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,minion,,,,,,,,,,,,,,minion} but should i keep using like this or should i change to something like this: User = function(){ this.minions = ...; this.getMinion = function(value){ for(var m in this.minions){ if(this.minions[m].id == value){ return this.minions[m]; break; } } } } and get it like this: user.getMinion(MinionID); Question: i get better performance using a "short" array but using loops every time i need a minion, or using "long" arrays, but no need for loop and getting values directly from the id "name"?

• programming can be taken as specialization - but what will I do still unclear [closed]

  - by C4CodeE4Exe

  I am bit confusing about my goals although whole motivation thing is $$$ but still there is something pushing me to pursue higher studies(being frustrated from boot-licking attitudes of peers and lottery system here in India for promotions,pay hikes and onshore opportunities). I am afraid I do not have any goals.I am software developer mainly in JAVA, but an ECE graduate.I want to work in programming languages. My problem is that I am not even Jack of all trades.I have experience in programming and thats where I am good(self-pro-claimed or atleast people say this treating them as a critics). I have decided to go with the wind and applying for programming languages as my specialization.But I know how to code,write test cases,how Perosnal and commercial IT insurances solution works.What I do not know is how to show that what I will do during my masters.I have no idea about what to showcase, how would my work ex will help me. totally oblivious thoughts... thanks waiting for replies....

• Will these tool tips get me penalized?

  - by user21100

  I have a page of 10 products. Each product has a list of (7) features associated with it. If a user hovers over the name of the feature, (ex., "Moisture resistance), a tooltip description displays. The descriptions ( a sentence or two), are loaded once on the page using Javascript, but the titles are not, so I essentially have a bunch of redundant tool tip titles. I am concerned this will look like keyword stuffing to the bots. Anyone know about this? Maybe I should load the feature titles with javascript as well?

• As a programmer, are you required to do timesheets?

  - by vcsjones

  Timesheets are something that I've never been fond of, but non-the-less something that is a requirement within my company. They don't bother me so much, but they seem to really grind some other people's gears. I suppose I have a few questions, and feedback would be great. Are you required to do timesheets, assuming you aren't a contractor? (That is understandable to me). What is the granularity of timesheets that you would be comfortable with or that you use? (ex: all entries must be under two hours). Would timesheets ever factor into your reasons for not accepting a job or leaving a current one? How has management within your organization justified timesheets if you aren't billing to a client?

• Developing Games for Samsung Smart TV

  - by Caner Öncü

  We are planning to develop a game for Samsung Smart TVs. Although those TVs support Flash and HTML5 other specs fail at supporting a game engine. For ex: Using an engine that needs GPU is not possible with the default Samsung smart tv set. Or... WebGL is supported with Samsung SDK 4.1 but we don't know if SDK 4.1 is available for Smart TV series between 7000-9000 or not. We have tried to communicate with Samsung but they don't really seem to respond. Is there anyone who has developed a game for Samsung Smart TVs? If there is, can you name the game engines that can work with those TVs?

• External hard-drive is "clicking" when idle [closed]

  - by mirumir

  I'm struggling with a very annoying issue: My new hard-drive (Samsung Spinpoint M8 1TB (HN-M101MBB) was build in an USB 3.0 external case (Lian Li EX-10QR) and formatted with ext4. When this hard-drive is connected to my Notebook via USB 2.0 it "klicks", the LED flashs too, every second, but only when it's idle! It stays silent, when something is copying or reading from it. But when this drive was formatted with ext3 or fat, it always remained silent. This also happens with a Western Digital WD10JPVT Scorpio Blue, but the "klicks" are even louder! System: 12.04 64-bit with Gnome-Shell. Any ideas how to approach this issue?

• Identifying methods with a specified Id in D [migrated]

  - by Ekyo777

  I want to have specific methods with a specific pattern recognized at compile time and registered along with a specified id trough mixins in a parent class. ex.: take a method 'X' from a class with a predetermined id:5, what I want is that, in a mixin in a parent class, method X will be registered as a delegate with its id to be called later on by its id. What would be the best way to specify the Id considering I want the id to be of type int and only the specified methods to be registered? should I (if it is even possible) do it with a custom annotation pretty much like the @property but with an argument, like: @autoregister(id) void method(...) if it is possible to do it this way, an example or a link to the documentation on how to do it would be nice since I didn't find it in the documentation.

• Estimating file transfer time over network?

  - by rocko

  I am transferring file from one server to another. So, to estimate the time it would take to transfer some GB's of file over the network, I am pinging to that IP and taking the average time. For ex: i ping to 172.26.26.36 I get the average round trip time to be x ms, since ping send 32 bytes of data each time. I estimate speed of network to be 2*32*8(bits)/x = y Mbps -- multiplication with 2 because its average round trip time. So transferring 5GB of data will take 5000/y seconds Am I correct in my method of estimating time. If you find any mistake or any other good method please share.

• Nouvelle étude de la répartition des systèmes d'exploitation mobiles, un graphique s'y penche par constructeur plutôt que par OS

  Nouvelle étude de la répartition des systèmes d'exploitation mobiles, un graphique s'y penche par constructeur plutôt que par OS C'est une question qui fait rage depuis toujours et à laquelle il est difficile d'apporter LA réponse, d'autant plus que les chiffres diffèrent suivant s'ils proviennent des éditeurs de systèmes d'exploitation ou bien des fabriquants de terminaux mobiles. Saura-t-on un jour avec certitude quel OS mobile domine le marché ? Un cabinet d'analystes tente d'apporter des statistiques claires et réalistes à ce sujet. En effet, quand il s'agit de l'observation des parts de marché par les utilisateurs de systèmes, c'est Android qui sort vainqueur (à 29% devant RIM et Apple qui son ex-aequo à 27 %).
