• What is the *correct* term for a program that makes use of multiple hardware processor cores?

  - by Ryan Thompson

  I want to say that my program is capable of splitting some work across multiple CPU cores on a single system. What is the simple term for this? It's not multi-threaded, because that doesn't automatically imply that the threads run in parallel. It's not multi-process, because multiprocessing seems to be a property of a computer system, not a program. "capable of parallel operation" seems too wordy, and with all the confusion of terminology, I'm not even sure if it's accurate. So is there a simple term for this?

• How to convert rmvb to mp4? (or, why ffmpeg doesn't work?)

  - by Tom Brito

  Hi, I'm trying to use this script to convert an rmvb video to mp4, but I'm having problems with the ffmpeg. In apt-get there's only ffmpeg0 and ffmpeg-dev, I installed both, but the script doesn't work, it's saying that ffmpeg was not found. Any hint on this? --update The script I'm talking about: #!/bin/bash tipo=$1 arqv=$2 resolucao=$3 tipoarq=$4 help() { clear echo "Convertor de Vídeos para MP4" echo "Parametro 1 = Tipo: (A - Arquivo/D - Diretório)" echo "Parametro 2 = Arquivo/Caminho" echo "Parametro 3 = Resolução" echo "Parametro 4 = Tipo de Arquivos de Entrada (rmvb, avi, mpeg)" } if [ "$tipo" = "" -o "$arqv" = "" -o "$resolucao" = "" -o "$tipoarq" = "" ]; then help; exit fi if [ "$tipo" = "D" ]; then count=`ls "$arqv"/*.$tipoarq | wc -l` else count=1 fi echo "$count arquivos encontrados para converter." x=0 while [ ! $x -ge $count ]; do x=`echo $x + 1 | bc` if [ "$tipo" = "D" ]; then nome=`ls "$arqv"/*.$tipoarq | head -n $x | tail -n 1` else nome=$arqv fi echo "Convertendo $nome ..." ffmpeg -i "$nome" -acodec libfaac -ab 128kb -vcodec mpeg4 -b 1200kb -mbd 2 -cmp 2 -subcmp 2 -s $resolucao "`echo $nome | sed "s/\.$tipoarq//g"`".mp4 done exit --update Using WinFF it gives: Unknown encoder 'libx264' I've installed both the existing packages libx264-67 and libx264-dev, but none solved.

• What naughty ways are there of driving traffic?

  - by Tom Wright

  OK, so this is purely for my intellectual curiosity and I'm not interested in illegal methods (no botnets please). But say, for instance, that some organisation incentivised link sharing in a bid to drive publicity. How could I drive traffic to my link? Obviously I could spam all my friends on social networking sites, which is what they want me to do, but that doesn't sound as fun as trying to game the system. (Not that I necessarily dispute the merit of this particular campaign.) The ideas I've come up with so far (in order of increasing deviousness) include: Link-dropping - This is too close to what they want me to do to be devious, but I've done it here (sorry) and I've done it on Twitter. I'm subverting it slightly by focusing on the game aspects rather than their desired message. AdWords - Not very devious at all, but effectively free with the vouchers I've accrued. That said, I must be pretty poor at choosing keywords, because I've seen very few hits (~5) so far. Browser testing websites - The target has a robots txt which prevents browsershots from processing it, but I got around this by including it in an iframe on a page that I hosted. But my creative juices have run dry I'm afraid. Does anyone have any cheeky/devious/cunning/all-of-the-above idea for driving traffic to my page?

• Obtaining a HBITMAP/HICON from D2D Bitmap

  - by Tom

  Is there any way to obtain a HBITMAP or HICON from a ID2D1Bitmap* using Direct2D? I am using the following function to load a bitmap: http://msdn.microsoft.com/en-us/library/windows/desktop/dd756686%28v=vs.85%29.aspx The reason I ask is because I am creating my level editor tool and would like to draw a PNG image on a standard button control. I know that you can do this using GDI+: HBITMAP hBitmap; Gdiplus::Bitmap b(L"a.png"); b.GetHBITMAP(NULL, &hBitmap); SendMessage(GetDlgItem(hDlg, IDC_BUTTON1), BM_SETIMAGE, IMAGE_BITMAP, (LPARAM)hBitmap); Is there any equivalent, simple solution using Direct2D? If possible, I would like to render multiple PNG files (some with transparency) on a single button.

• What are the Top Developer Productivity Tools/Plugins for Java in Eclipse?

  - by Ryan Hayes

  I personally use CodeRush in Visual Studio 2010 to do refactoring, write code faster with templates and generally navigate my code 10 times faster than stock VS. Recently, I've been working on another Android app and got to thinking...What are the top productivity plugins for Eclipse? Preferably free. I'm looking for plugins that help write in Java, not PHP or Rails or any of the other languages Eclipse supports.

• Management Reporter Installation – Lessons Learned

  - by Ryan McBee

  After successfully completing several installations of Management Reporter this year, I wanted to share a few lessons learned that should help you. First, you will want to make sure that you install Management Reporter under a domain account as opposed to a local system or network service account. Management Reporter gives you the option to install under these accounts, but it is a be a best practice approach to use a domain account. Upon installation of Management Report, you will want to make sure that Directory Browsing is enabled within the IIS server of your site or you will have problems when you go to use Management Reporter. By default, it will be disabled in Server 2008 R2 and you will need to make the setting change under the Actions pane shown below. Lastly, you will want to make sure that SQL Server is running under a domain account. I have had multiple situations where reports have been stuck in the Queued status rather than Processing status of Management Reporter. After reviewing resolution 5 of KB 2298248, it was determined that running SQL Server under a domain account is the way to go.

• Web developer has become uncooperative, what should we do to rescue our site? [closed]

  - by TOM

  What can an individual or a company do if the web designer who has designed their website becomes completely uncooperative? In our case He refuses to meet with us for discussions. He refuses to give us training on the effective use and management of the website he has designed for us (and has been paid in full for) despite this training being part of the original contract. Last year he disappeared for a number of months ,refused to answer emails or phobe calls and was totally unavailable to help us He refuses to give us the details of the hosting of our website. We have totally lost faith in this arrogant and unreasonable guy and would like to break off all relationships with him but ,it appears, he's got us over a barell

• 12.10 x64 - RTL8188CE - Intermittent/Slow Internet Connection

  - by Nicholas Ryan Bowers

  I have to reset my internet connection often to get it to work. When it does work, it's definitely slower than when I'm on my Windows installation. My computer uses an RTL8188CE wireless card from Realtek. I'm running the 64-bit version of Ubuntu 12.10. Power management is not on. I've read on other sites that some people fixed the issue pertaining to this wireless card by downloading and installing the drivers from the Realtek site, but it seems as if that only helped people with 32-bit installations. Anyone have any luck with this specific wireless card?

• What do I do if a user uploads child pornography?

  - by Tom Marthenal

  If my website allows uploading images (which are not moderated), what action do I take if a user uploads child pornography? I already make it easy to report images, and have never had this problem before, but am wondering what the appropriate response is. My initial thought is to: Immediately delete (not just make inaccessible) the image File a report with the National Center for Missing and Exploited Children with all information I have on the user (IP, URL, user-agent, etc.), identifying myself as the website operator and providing contact information Check any other images uploaded by that IP user and prevent them from uploading in the future (this is impossible, but I can at least block their account). This seems like a good way to be responsible in reporting, but does this satisfy all of my legal and moral responsibilities? Would it be better not to delete the image and to just make it inaccessible, so that it can be sent to the National Center for Missing & Exploted Children, the police, FBI, etc?

• Dock with dual external DVI monitors with Intel + Nvidia Optimus?

  - by Ryan

  I have a Dell Latitude E6420 laptop plugged into a docking station, and the dock has 2 monitors (connected with DVI). Also note that I've installed Ubuntu alongside (dual-boot) Windows 7. I can't get the dual monitors to work both on Ubuntu (either 11.10 or 12.04) and Windows 7. When I run lspci | grep VGA, I get: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: nVidia Corporation GF108 [Quadro NVS 4200M] (rev a1) If I then reboot and uncheck Optimus setting in the BIOS during reboot, I'm able to get the dual monitors to work in Ubuntu 12.04 (but I need to configure them every boot in Nvidia Settings). When I run lspci | grep VGA, I get: 01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [Quadro NVS 4200M] (rev a1) But then if I reboot into Windows (leaving the Optimus unchecked), Windows can't detect external monitors, and the resolution is unacceptably low. I've seen on many forum posts that this particular graphics card setup causes lots of headaches. I haven't been able to resolve my problem yet. How can I use my external display on my laptop with intel and nvidia video cards? How to use external displays with Intel driver on a NVidia/Intel hybrid system nVidia Optimus , Unity 3D and Dual Monitors "Just use VGA instead of DVI" isn't an option because my dock has only 1 VGA port (and 2 DVI). Switching the BIOS setting on every reboot and then reconfiguring the display settings every time is tedious, time-consuming, and impractical. Do you know how to make this work smoothly? Thanks for your help! P.S. see also: http://superuser.com/questions/434358/dell-latitude-e6420-dual-boot-ubuntu-windows-7-optimus-graphics-problems

• Install using a Logitech Keyboard and mouse with bluetooth dongle?

  - by Ryan

  I'm trying to install 12.10 on my system, but my mouse and keyboard are not working during installation. I use the Logitech MX5500 Bluetooth mouse+keyboard combo with a Bluetooth dongle. My keyboard and mouse work in my UEFI bios, and during the Windows 7/8 installation. My keyboard also works in the Ubuntu screen that allows me to set options, install, use the live cd, etc, before boot. I'm wondering if anyone knows a way to get this dongle working during the installation process so that I can actually install 12.10.

• How do you turn a cube into a sphere?

  - by Tom Dalling

  I'm trying to make a quad sphere based on an article, which shows results like this: I can generate a cube correctly: But when I convert all the points according to this formula (from the page linked above): x = x * sqrtf(1.0 - (y*y/2.0) - (z*z/2.0) + (y*y*z*z/3.0)); y = y * sqrtf(1.0 - (z*z/2.0) - (x*x/2.0) + (z*z*x*x/3.0)); z = z * sqrtf(1.0 - (x*x/2.0) - (y*y/2.0) + (x*x*y*y/3.0)); My sphere looks like this: As you can see, the edges of the cube still poke out too far. The cube ranges from -1 to +1 on all axes, like the article says. Any ideas what is wrong?

• Removing date from Google SERP

  - by Tom Gullen

  We are going through our site analysing the SEO. I find that sometimes on a google results page, some results show a date, others don't. Example (from same query): I prefer the result not to have the date in it, as 20 Oct 2009 probably has an adverse effect on the clickability of the result. Is this Google putting it in? Or the page itself? Or a combination of both (IE, if over a certain age, it includes date). The two URLs are: http://www.scirra.com/forum/perlin-noise-plugin_topic38498.html http://www.scirra.com/forum/dungeon-maze-generator_topic40611.html Any way to remove the dates? I'm thinking, if the age of the thread is 4 months don't display the date on the page, then Google might not find a date reference for it?

• Scalable solution for website polling

  - by Tom Irving

  I'm looking to add push notifications to one of my iOS apps. The app is a client for a website which doesn't offer push notifications. What I've come up with so far: App sends a message to home server when transitioning to background, asking the server to start polling the website for the logged in user. The home server starts a new process to poll for that user. Polling happens every so many seconds / minutes. When the user returns to the iOS app, the app sends a message to the home server to stop polling. The home server kills the process polling for the user. Repeat. The problem is that this soon becomes stupid: 100s of users means 100s of different processes. It's just not scalable in the slighest. What I've written so far is in PHP, using CURL to do the polling and I started with PHP a few days ago, so maybe I'm missing something obvious that could help me with this. Some advice would be great.

• Are there open source alternatives to Bitbucket, Github, Kiln, and similar DVCS browsing and management tools?

  - by Ryan Taylor

  I am aware of several tools/services that provide DVCS browsing and management such as Bitbucket, Github, Kiln, SCM-Manager and Rhodecode. However, the use case I am considering is one such that: Any source code must reside on an employers internal servers. The solution must be open source. It should provide a Bitbucket or Github like experience, including a project wiki, repository browsing and management, and social coding aspects such as code review. The solution should have mercurial support (if not support for other DVCSs). Of these, only SCM-Manager and RhodeCode come close as they can be installed on your own servers and are open source. However they do not have the Bitbucket or Github experience. There is no issue tracker or wiki and the UI, while functional, is not up to par with Github or Bitbucket. I can get close with Trac or Redmine with their repository browsers but unfortunately they do not have any repository management capabilities. Are there other open source tools out there that would provide a similar experience to Bitbucket, Github or Kiln?

• Tool to search for packages whose installed version does not match any version from a repository?

  - by Ryan Thompson

  I just upgraded from Lucid to Maverick, and as expected, all my PPAs were disabled. I have re-enabled most of the ones that I want, but I would like to get a list of all packages that I installed from PPAs that I no longer have enabled. I feel that the best way to do this would be to search for all packages where the currently installed version of that package does not match any version from a currently-enabled repository. Is there an easy way to search for such packages. Command-line solutions welcome.

• How can I make sure that I'm actually learning how to program rather than simply learning the details of a language?

  - by Ryan

  I often hear that a real programmer can easily learn any language within a week. Languages are just tools for getting things done, I'm told. Programming is the ultimate skill that must be learned and mastered. How can I make sure that I'm actually learning how to program rather than simply learning the details of a language? And how can I develop programming skills that can be applied towards all languages instead of just one?

• /etc/init.d Character Encoding Issue

  - by Ryan Rosario

  I have a script in /etc/init.d on an EC2 image that, on machine startup, pulls in source code via SVN, builds it, and then runs it using Ant. The source code is Java. Within this code is a call to the Weka library which writes a file to disk. On most Ubuntu AMIs, and my home machines' versions of Ubuntu, there is no issue. The problem is that with certain versions/AMIs of Ubuntu, Unicode characters in the file are replaced with question marks ('?'). If I run the job manually on the trouble instance, Unicode is output to file correctly, but not when run from /etc/init.d. What might be causing this problem and how can I fix it so that Unicode characters appear correctly in files written from /etc/init.d processes?

• Moving my sprite in XNA using classes

  - by Tom

  Hey, im a newbie at this programming lark and its really frustrating me. I'm trying to move a snake in all directions while using classes. Ive created a vector2 for speed and ive attempted creating a method which moves the snake within the snake class. Now I'm confused and not sure what to do next. Appreciate any help. Thanks :D This is what i've done in terms of the method... public Vector2 direction() { Vector2 inputDirection = Vector2.Zero; if (Keyboard.GetState().IsKeyDown(Keys.Left)) inputDirection.X -= -1; if (Keyboard.GetState().IsKeyDown(Keys.Right)) inputDirection.X += 1; if (Keyboard.GetState().IsKeyDown(Keys.Up)) inputDirection.Y -= -1; if (Keyboard.GetState().IsKeyDown(Keys.Down)) inputDirection.Y += 1; return inputDirection * snakeSpeed; } Appreciate any help. Thanks :D EDIT: Well let me make everything clear. Im making a small basic game for an assignment. The game is similar to the old snake game on the old Nokia phones. I've created a snake class (even though I'm not sure whether this is needed because im only going to be having one moving sprite within the game). After I written the code above (in the snake class), the game ran with no errors but I couldn't actually move the image :( EDIT2: Thanks so much for everyones responses!!

• Why do my Google sitelinks show gibberish for a PDF link?

  - by Tom

  I have a website which Google lists nicely along with site links. One of the site links - to a PDF file - shows un-human gibberish e.g 67,8;45:: 56 83 @7<1. (7/0;,*;: /59( (7/0;,;<7, <7)(60:4 (9<7 /+ +2, VU I thought it might be due to the PDF's title property so I changed it. But there hasn't been an improvement to the site link. Other PDF site links are fine and display the title property as desired. Does anyone know how I might rectify this problem or what might be the cause? My uninformed guess is it's some transliteration problem between code and display text which, I suppose, means I ought to recondition the PDF file in some way. Not sure how.

• Validating allowed characters or validating disallowed characters

  - by Tom

  I've always validated my user input based on a list of valid/allowed characters, rather than a list of invalid/disallowed characters (or simply no validation). It's just a habit I picked up, probably on this site and I've never really questioned it until now. It makes sense if you wish to, say, validate a phone number, or validate an area code, however recently I've realised I'm also validating input such as Bio Text fields, User Comments, etc. for which the input has no solid syntax. The main advantage has always seemed to be: Validating allowed chars reduces the risk of you missing a potentially malicious character, but increases the risk the of you not allowing a character which the user may want to use. The former is more important. But, providing I am correctly preventing SQL Injection (with prepared statements) and also escaping output, is there any need for this extra barrier of protection? It seems to me as if I am just allowing practically every character on the keyboard, and am forgetting to allow some common characters. Is there an accepted practice for this situation? Or am I missing something obvious? Thanks.

• Disable alt + tab moving windows by itself

  - by Lie Ryan

  Whenever I press Alt + Tab , Unity moves the window I'm switching to so that the whole window is inside the screen. This behavior is excruciatingly annoying because I often move a window (usually text editors) partially outside the current screen so I can view another window below it (usually a browser). Every time I Alt + Tab back to the text editor, I'm getting an unnecessary virtual screen switch, and Unity is rearranging the windows behind my back. For instance, here is a browser and text editor on Virtual Screen 1 (top left), note that the text editor is partially outside the current screen: Then I Alt-Tab to the browser (or clicked on it): Next, I Alt + Tab again to get back to the text editor, but Alt-Tab switched me to Virtual Screen 4 (bottom right) because a larger percentage of the text editor window is on virtual screen 4 than in virtual screen 1; and the browser is no longer in the screen. Also note that the text editor window moves from being on the bottom-right to the top-left, which is very disorienting as I can no longer keep track of where any of my windows are since they all keep moving around by themselves.. How do I disable this behavior? I don't want to have any virtual screen switch when Alt + Tab , especially since Alt + Tab does not list windows that is completely not in the current virtual screen anyway.
