• is there a formal algebra method to analyze programs?

  - by Gabriel

  Is there a formal/academic connection between an imperative program and algebra, and if so where would I learn about it? The example I'm thinking of is: if(C1) { A1(); A2(); } if(C2) { A1(); A2(); } Represented as a sum of terms: (C1)(A1) + (C1)(A2) + (C2)(A1) + (C2)(A2) = (C1+C2)(A1+A2) The idea being that manipulation could lead to programatic refactoring - "factoring" being the common concept in this example.

• How to get scripted programs governing game entities run in parallel with a game loop?

  - by Jim

  I recently discovered Crobot which is (briefly) a game where each player codes a virtual robot in a pseudo-C language. Each robot is then put in an arena where it fights against other robots. A robots' source code has this shape : /* Beginning file robot.r */ main() { while (1) { /* Do whatever you want */ ... move(); ... fire(); } } /* End file robot.r */ You can see that : The code is totally independent from any library/include Some predefined functions are available (move, fire, etc…) The program has its own game loop, and consequently is not called every frame My question is: How to achieve a similar result using scripted languages in collaboration with a C/C++ main program ? I found a possible approach using Python, multi-threading and shared memory, although I am not sure yet that it is possible this way. TCP/IP seems a bit too complicated for this kind of application.

• What's the normal way machine-learning algorithms are integrated into normal programs?

  - by Benjamin Pollack

  I'm currently taking a machine learning course for fun, and the course heavily focuses on Matlab/Octave to write the code. One thing mentioned in the course is that, while Matlab/Octave are great for prototyping, they're very rarely used for production algorithms. Instead, those algorithms are typically rewritten in C++/Python/etc., using appropriate libraries, before reaching customers. Fair enough; I get that. But here's my question: is that done for cultural reasons, for technical reasons, or because there is really no language that provides Matlab/Octave-like fluidity, but in a compiled form that can be linked from C/C++/$MainstreamLanguage? The game industry uses Lua for game logic because it's easy to embed, and vastly superior for expressing things like AI. Likewise, there are Prolog variants for rules-heavy applications, Scheme variants for compilers, and so on. If there's a matrix equivalent language, what is it? If there isn't, why is this field different?

• Why is Ubuntu 12.04 taking very long to start and run programs?

  - by Anna

  I have a Toshiba laptop with 2.8 gb of ram, 1.87x2 GHz processor, and Ubuntu 12.04 64 bit on it as a partition installed with wubi. It takes 5-10 mins to start up, and opening any program (such as Chromium, Chrome, Skype, Firefox, Thundermail, etc) takes over half a minute. I stopped using Unity because my graphic card couldn't handle it and swapped over to Cinnamon. It's a little better, but everything is still really really slow. Any suggestions/solutions?

• Legitimate use of the Windows "Documents" folder in programs.

  - by romkyns

  Anyone who likes their Documents folder to contain only things they place there knows that the standard Documents folder is completely unsuitable for this task. Every program seems to want to put its settings, data, or something equally irrelevant into the Documents folder, despite the fact that there are folders specifically for this job1. So that this doesn't sound empty, take my personal "Documents" folder as an example. I don't ever use it, in that I never, under any circumstances, save anything into this folder myself. And yet, it contains 46 folders and 3 files at the top level, for a total of 800 files in 500 folders. That's 190 MB of "documents" I didn't create. Obviously any actual documents would immediately get lost in this mess. My question is: can anything be done to improve the situation sufficiently to make "Documents" useful again, say over the next 5 years? Can programmers be somehow educated en-masse not to use it as a dumping ground? Could the OS start reporting some "fake" location hidden under AppData through the existing APIs, while only allowing Explorer and the various Open/Save dialogs to know where the "real" Documents folder resides? Or are any attempts completely futile or even unnecessary? 1For the record, here's a quick summary of the various standard directories that should be used instead of "Documents": RoamingAppData for user-specific data and settings. This is the directory to use for user-specific non-temporary data. Anything placed here will be available on any machine that a given user logs on to in networks where this is configured. Do not place large files here though, because they slow down login/logout in such environments. LocalAppData for user-and-machine-specific data and settings. This data differs for every user and every machine. This is also where very large user-specific data should be placed. ProgramData for machine-specific data and settings. These are the same regardless of which user is logged on, and will not roam to other machines in a network. GetTempPath for all files that may be wiped without loss of data when not in use. This is also the place for things like caches, because like temporary data, a cache does not need to be backed up. Place your huge cache here and you'll save your user some backup trouble. "Documents" itself should only ever be used if the user specified it manually by entering a path or selecting it in a Save dialog. That is the only time it is ever appropriate to save stuff in "Documents".

• OpenSolaris and its killer features. Coming to a GNU/Linux near you?

  <b>Free Software Magazine:</b> "When we think of free operating systems we tend to think overwhelmingly of the big hitters (all GNU/Linux) like Debian, Ubuntu, Fedora and Mandriva and then of those niche distros that have been designed for low end systems or for specialist purposes like security and forensics. But Oranges are not the only fruit"

• Assign programs permanently to different sound-outputs in Pulseaudio?

  - by Mood

  I want to assign Skype input and output to my USB-headset while the rest of my laptop uses the internal sound-card. This is an easy task with PulseAudio Volume control (pavucontrol). The only problem I have is every time a call is made I manually have to set the output and input for Skype to my USB-device . When I hang up, Skype disappears from Volume Control. It reappears again with the next call only this time the default sound-card is selected again. It shouldn’t be hard to let PulseAudio look or the USB-headset is connected when Skype audio comes is before selecting the default. The way to do it is obvious not through Volume Control.

• How do I simplify a 2D game grid for level management while keeping its by-pixel features?

  - by Eric Thoma

  (I cross-posted this from StackOverflow as this seems to be a more appropriate forum. I've looked around a little here and I did not find an answer, so I hope this is not a recurring question.) This is a question dealing with 2D world design. I am playing around by creating a 2D bird's eye view shooter game, and I am looking to make the game sleek and advanced. I hope to be able to write physics so projectiles have momentum and knock-down properties. I am immediately running into the problem of world design. I need a way to have level files that store everything there is about a game. This is easiest by just having a grid of objects. But there are thin-walls and other objects that don't seem to fit into a traditional cell of a grid. I want to be able to fit all these together so I can streamline level design; so I don't have to put in the exact pixel-specific start and end of a wall. There doesn't seem to be an obvious translation from level file to game without forcing myself into a pacman-life scenario, meaning a scenario where the game feels boxy and discrete. There is a contrast between the smoothly (relatively) moving characters and finite jumps in a grid. I would appreciate an answer that would describe implementation options or point me to resources that do. I would also appreciate references to sites that teach game design. The language I am using is Java (although I would love to use C or C++, but I can never find convenient resources in those languages). Thank you for any answers. Please leave any questions in the space below; I will be able to answer them later tonight (28th Nov).

• What are some good game development programs for kids?

  - by John Giotta

  I know a very bright little boy who excels in math, but at home he's glued to his Nintendo DS. When I asked him what he wanted to do when he grew up he said "Make video games!" I remember a few years there was mention of a MIT software called Scratch and thought maybe this kid can do want he wants to do. Has anyone used any of the "game development" for kids softwares out there? Can you recommend any?

• Advertisement programs that allow "clickjacking" (earning advertisement revenues by popups generated by clicks on the website)?

  - by Tom

  Whether clickjacking is an ethically responsible way of earning advertisement revenues is a subjective discussion and should not be discussed here. However, it appears that quite a lot of popular sites generate "popups" when you click either of their links or buttons. An example is the Party Poker advertisement (I am sure many of you will have seen this one). I wonder though, what kind of advertisement companies allow such techniques? Surely Google Adsense does not? But which do, and are they reliable partners?

• How do you turn on the customizable gnome-panel features (like gnome-applets) in Precise?

  - by chriv

  I resurrected a broken laptop today. I took out the HDD, put it in a USB 3.0 enclosure, and created a VM that would use it. It was running lucid. I took a screenshot of the desktop before I started "do-release-upgrade", because from experience, I will never have my GUI back the way I want it again. I know how to install gnome-panel to get back the "Gnome Classic" session option. I know how to put my minimize, maximize, and close buttons back in the upper-right hand corner of windows (where they belong). I know how to use gdm instead of lightdm. Unity gets worse in every version (and the other desktop OS is going to be even worse with Metro). Here's what I don't know (in order of importance): 1. How do you make the panels in gnome (gnome-panel, to be precise) customizable again (like they were in older versions of Ubuntu)? 2. How do you install applets in the panels now (right-click is now ignored)? 3. How can you customize all of the window elements (like you could in older versions of Ubuntu)? I can't remember much about maverick, natty, or oneiric (except their names), so I don't know exactly when I lost these capabilities. Edit: (no screenshot), my StackExchange reputation (on other StackExchange sites) doesn't carry over to this site, so I can't post the screenshot. Take a look at the panels in the screen hot. They are nice, compact, and VERY functional (disk mounter applet, frequently used shortcuts, workspaces, show desktop, kill window, and trash icons, etc.) Notice how small the fonts (and how little real estate they waste). You can't notice the compact title bars, fonts, and window icons in this screen shot (since I redacted the rest of the desktop), but it's the same story there. Please help. I don't want to learn another distro, but Ubuntu gets less customizable with every "upgrade." Screenshot (not an inline image, since I don't have the reputation yet)... i.stack.imgur.com/puoUT.png

• Best way to trigger editing and dynamically show editing features? [on hold]

  - by Tim Marshall

  Page In Question: http://rafflebananza.com/admin/StatisticalData/expenses/expenses.html Hiya Everyone, On my page, I have an 'Actions' drop down to the top-right hand side of the page. This actions drop down I would like to have an action to 'Enable Editing'. Upon clicking to enable editing, I would like a PHP variable modified from 'EnableEditing = false' to 'EnableEditing = true'. Why I would like to use PHP maybe questionable, here is why I would like to use PHP under my understanding to clarify; Sections on my page will show to different administrators depending on their level. Upon enabling editing mode, certain contents will then dynamically. <?php if ($_SESSION['user_level_status'] < 2) { if ($editing = enabled) { show this } else { show this } } ?> Something similar to this, I'm new at PHP so this may look incorrect. The question really is, is PHP the correct language to use to trigger editing and how can I do this please? Best Regards, Tim

• What is the Ubuntu equivalent of the Windows programs Belarc or PC Wizard?

  - by CeltaWeb

  I provide technical support for several high schools in Spain and I have been building up a inventory of the schools machines. On the windows only computers I normally run PC Wizard to quickly get a good overview of the machines hardware, software and network settings. Is there an equivalent tool preferable with a GUI and an export option to html or pdf in Ubuntu. I have tried a few options such as: Gnomes gconf-editor hardinfo (GUI) lshw (CLI) I'm just looking for an all in one application that builds a detailed profile of the installed software, hardware and network setting of a particular machine. I have found Sysinfo which is quite good, it displays the most important hardware info and allows you to save it to a text file with a neat GUI. I'm still looking for a more complete solution but it's a good start.

• What is approximate cost to develop iPhone/iPad app? Features described

  - by innodeasapps

  Need your help guys... I was working as an iPhone developer since last few months. And just a month ago I left the job, and now i got an offer to develop an iPhone/iPad app. I need to develop an universal app which has frames like PicFrame in which photos must adjust accordingly, with customizable frames, few photo effects like in instagram (Not exactly same but something like it) and then user can share photos on Facebook, tumbler,dropbox, etc. I might need around 30 days time to develop the desired app. Note that designing is not my part, I need to develop and test it thoroughly. I have no idea how much price should I ask to develop such app. As here is the place where we all developers meet, I feel I would get proper guidance. Thank you in advance...

• Should I install programs from a source tarball (`.tar.gz`), from the Ubuntu Software Centre, or from elsewhere?

  - by Flimm

  There are several ways to install an application in Ubuntu: You can download a source tarball (generally a .tar.gz or a .tar.bz2 file) and install it manually. (See How to install a .tar.gz (or .tar.bz2) file?) You can download a .deb file and install it manually, using dpkg or the Software Centre. You can search for the application in the Ubuntu Software Centre and install it there, or use apt with the official Ubuntu repositories. You can find a PPA or a third-party repo, and install it from there. What are the pros and cons of each method? Please discuss security implications, frequency of updates and program reliability of each method in your answer.

• Conventions for the behavior of double or triple "click to select text" features?

  - by John Sullivan

  Almost any mature program that involves text implements "double click to select the word" and, in some cases, "triple click to select additional stuff like an entire line" as a feature. I find these features useful but they are often inconsistent between programs. Example - some programs' double clicks do not select the ending space after a word, but most do. Some recognize the - character as the end of a word, others do not. SO likes to select the entire paragraph as I write this post when I triple click it, VS web developer 2005 has no triple click support, and ultra-edit 32 will select one line upon triple clicking. We could come up with innumerable inconsistencies about how double and triple click pattern matching is implemented across programs. I am concerned about how to implement this behavior in my program if nobody else has achieved a convention about how the pattern matching should work. My question is, does a convention (conventions? maybe an MS or Linux convention?) exist that dictates how these features are supposed to behave to the end user? What, if any, are they?

• How to do i18n and create Windows Installer of Haskell programs?

  - by Aufheben

  I'm considering using Haskell to develop for a little commercial project. The program must be internationalized (to Simplified Chinese, to be specific), and my customer requests that it should be delivered in a one-click Windows Installer form. So basically these are the two problems I'm facing now: I18n of Haskell programs: the method described in Internationalization of Haskell programs did work (partially) if I change the command of executing the program from LOCALE=zh_CN.UTF-8 ./Main to LANG=zh_CN.UTF-8 ./Main (I'm working on Ubuntu 10.10), however, the Chinese output is garbled, and I've no idea why is that. Distribution on Windows: I'm used to work under Linux and build & package my Haskell programs using Cabal, but what is the most natural way to create a one-click Windows Installer from a cabalized Haskell package? Is the package bamse the right way to go? ------ Details for the first problem ------ What I did was: $ hgettext -k __ -o messages.pot Main.hs $ msginit --input=messages.pot --locale=zh_CN.UTF-8 (Edit the zh_CN.po file, adding Chinese translation) $ mkdir -p zh_CN/LC_MESSAGES $ msgfmt --output-file=zh_CN/LC_MESSAGES/hello.mo zh_CN.po $ ghc --make Main.hs $ LANG=zh_CN.UTF-8 ./Main And the output was like: This indicates gettext is actually working, but for some reason the generated zh_CN.mo file is broken (my guess). I'm pretty sure my zh_CN.po file is encoded in UTF-8. Plus, aside from using System.IO.putStrLn, I also tried System.IO.UTF8.putStrLn to output the string, which didn't work either.

• No Microsoft Security Essentials for Windows 8. So, how to access similar Defender features/settings?

  - by Chris W. Rea

  I just installed Windows 8 Pro. One of the first things I went to do is install Microsoft Security Essentials, thinking I still needed add-on security software, but I've learned here that it isn't required for Windows 8. Witness: Got Windows 8 or Windows RT? Windows Defender for Windows 8 and Windows RT provides the same level of protection against malware as Microsoft Security Essentials. You can't use Microsoft Security Essentials with Windows 8, but you don't need to — Windows Defender is already included and ready to go. [...] All well and good. However, on Windows 7, once you installed Microsoft Security Essentials, you got a tray icon, and from there you could access the features of MSE, such as perform custom scans, turn off real-time protection (temporarily, of course), check for updates, etc. However, Defender on Windows 8 doesn't display a tray icon – and yes, I've already made sure I'm displaying all icons in the notification area. So, how to access the similar specific features of Windows Defender on Windows 8?

• Install iphone sdk DMG file on iMac but I can't find where any of the programs are located

  I just download the iPhone DMG file from apple and installed in on my new iMac (by following these directions: link text). The problem is, I can't seem to find where any of the programs got installed. I can't find XCode or Interface Builder in the applications list and everytime I click on the "iPhone SDK" icon in the applications list, it re-opens finder with the same packages that I am trying to install. P/S: I am completely new to the the Mac world so I might be doing everything completely wrong.

• T42 Thinkpad, USB boot, CF for programs and storage?

  - by Tom K.

  Is this feasible? I have a Thinkpad T40. I'd like to get one of the tiny USB drives (like the Verbatim Store 'n' Stay series) of sufficient size to handle basic Linux OS booting (8GB?), then put 16Gb or greater memory card (SD or CF) in the PCMCIA slot with appropriate adapter for additional application programs and data storage. I know I could get a used or refurb HD, but I've had reliability issues in the past. I don't believe that new IDE drives are available.

• What is the real meaning of the "Select a language [for] non-Unicode programs..." dialog?

  - by Joshua Fox

  What is the real meaning of the "Select a language to match the language version of the non-Unicode programs you want to use" dialog under Control Panel-Regional Settings-Advanced in WinXP and Win2003? According to the dialog text, Windows will use this to display the resource strings such as menus. The treatment of text files is application-specific, so this setting will not affect that. But can I expect any other change in behavior from this setting? Any insights into what is really going wrong?
