• Why won't videos on a particular website play under Ubuntu 13.04?

  - by Sadi

  Very oddly, I cannot watch any videos a TV channel website, for example this one: http://www.kanald.com.tr/GalipDervis/Videolar/ I can see from the frame source that it contains an embedded Adobe Flash video and some Java scripts (all of which don't pose any problems elsewhere). I've tried different web browsers (Chrome/Chromium/Firefox), but it seems I have some sort of video codec problem in my system. I have installed all sorts of gstreamer plugins, codecs, etc. (maybe too many?) to avoid such problems, but strangely I can watch these videos using Linux Mint 15 Live Session on the same machine. I wonder how I can find out why a particular video (like this one) won't work on my system?

• Add Custom Color Changing RGB LED Lighting to Your Next Project

  - by Jason Fitzpatrick

  While this specific project is a really neat back-lit bookcase with customizable LED lights galore, you could easily add the exact same setup to just about anything you wanted to give some LED love. The core of the project is a set of addressable LED modules, an Arduino board, and a simple bit of code. You could use it to make a 70s style mood lighting box, add color changing accents to your media room, or any other number of fun projects just by cloning this project and extending/shortening the wires where appropriate. The control module allows for solid colors, multi-colors, and animations. Hit up the link below for more information including the source code.

• Crawling for geotagged data

  - by abe3

  I have no experience with web crawlers -- but I know that Apache maintains an open source web crawler called "Lucene." How would I go about writing such a crawler to search the web for geo tagged data close to a particular location? What would a general road map look like? How do I pick which slice of the web to crawl? Do I use regular expressions to find things that look like longitudes and latitudes? What does a general sketch of that solution look like?

• Alternatives to the GPL

  - by Bane

  I made a game, and I am currently making a game engine. I want them both to be completely free and open source. What license should I choose? I was reading a bit on GPL, but that seems to be more suited for system code and libraries, AFAIK, as it doesn't permit the use of code for proprietorial software - which, in turn, implies that the code can be used in the first place. I can see that, obviously, game engines can be considered libraries, and therefor be used, but what about game code? Is there an alternative to GPL?

• building bittorrent client from scratch

  - by Bill

  I'm new to programming. I find reading introductory programming books boring. I think these doesn't teach enough of the problem solving skills that I need. So I decided to build a bitTorrent client. I think I understand to some point how the protocol works. I have also downloaded the source code of deluge bittorrent client. I have access to python documentation too. I need to know if there are some resources available that can help me build a bitTorrent client that are more detailed than the wikipedia article here: http://en.wikipedia.org/wiki/BitTorrent

• ORA- 01157 / Cant connect to database

  - by Tom

  Hi everyone, this is a follow up from this question. Let me start by saying that i am NOT a DBA, so i'm really really lost with this. A few weeks ago, we lost contact with one of our SID'S. All the other services are working, but this one in particular is not. What we got was this message when trying to connect ORA-01033: ORACLE initialization or shutdown in progress An attempt to alter database open ended up in ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf' I tried to shutdown / restart the database, but got this message. Total System Global Area 566231040 bytes Fixed Size 1220604 bytes Variable Size 117440516 bytes Database Buffers 444596224 bytes Redo Buffers 2973696 bytes Database mounted. ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf' When all continued the same, I erased the dbf files (rm xxx_data.dbf xxx_index.dbf), and recreated them using touch xxx_data.dbf. I also tried to recreate the tablespaces using `CREATE TABLESPACE DATA DATAFILE XXX_DATA.DBF` and got Database not open As I said, i don't know how bad this is, or how far i'm from gaining access to my database (well, to this SID at least, the others are working). I would imagine that a last resource would be to throw everything away, and recreating it, but I don't know how to, and I was hoping there's a less destructive solution. Any help will be greatly appreciated . Thanks in advance.

• Recommendations for finding part-time consultancy work

  - by Mark Heath

  Although I have a full-time development job, I have occasionally done some part-time paid work in evenings / weekends for various people who have contacted me as a result of open-source projects I have worked on. It's a nice way to earn a bit of extra cash, but obviously it is not always available. My question is, what is a good way of getting your name out there to do some small projects? I have seen a few programmers-for-hire type websites, but I don't know which I can trust or whether there are too many people willing to work for very low prices. Also, being UK based, I would want something which did not assume I have a US bank account.

• Troubleshooting Blocked Transaction in SQL Server

  - by ChrisD

  While troubleshooting a blocked transaction issue recently, I found this code online.  My apologies in not citing its source, but its lost in my browse history some where.   While the transaction is executing and blocked, open a connection to the database containing the transaction and run the following to return both the SQL statement blocked (the Victim), as well as the statement that’s causing the block (the Culprit)   -- prepare a table so that we can filter out sp_who2 results DECLARE @who TABLE(BlockedId INT, Status VARCHAR(MAX), LOGIN VARCHAR(MAX), HostName VARCHAR(MAX), BlockedById VARCHAR(MAX), DBName VARCHAR(MAX), Command VARCHAR(MAX), CPUTime INT, DiskIO INT, LastBatch VARCHAR(MAX), ProgramName VARCHAR(MAX), SPID_1 INT, REQUESTID INT) INSERT INTO @who EXEC sp_who2 --select the blocked and blocking queries (if any) as SQL text SELECT ( SELECT TEXT FROM sys.dm_exec_sql_text( (SELECT handle FROM ( SELECT CAST(sql_handle AS VARBINARY(128)) AS handle FROM sys.sysprocesses WHERE spid = BlockedId ) query) ) ) AS 'Blocked Query (Victim)', ( SELECT TEXT FROM sys.dm_exec_sql_text( (SELECT handle FROM ( SELECT CAST(sql_handle AS VARBINARY(128)) AS handle FROM sys.sysprocesses WHERE spid = BlockedById ) query) ) ) AS 'Blocking Query (Culprit)' FROM @who WHERE BlockedById != ' .'

• A Virtual(Box) Christmas!

  - by Gilles Gravier

  Hello and merry Christmas everybody!Yes. This year, it's a v4.0 Xmas! VirtualBox just came out with a new major version release. Version 4.0 is available at : http://www.virtualbox.org/wiki/Downloads ... and of course, it's open source, and it's free. And I suggest (strongly) that you also download the free Extension Pack from the same page... Brings USB 2.0 emulation and more!I upgraded the version on my Solaris Express (get that from : http://www.oracle.com/solaris/index.html and follow the Download Solaris Express link on the right) laptop (pfexec pkgrm SUNWvbox and then pfexec pkgadd -d the .pkg in the compressed archive file, and install the extensions from the VBox GUI once it's launched). If you are on an old fashion OS without proper RBAC, replace pfexec by sudo. Which you can also do on Solaris if you really want to. :)I tell you, it's Christmas, for sure!Merry VBox!Gilles.

• Why is my hg workbench & Adobe Reader toolbar icon a blank white page?

  - by Zasurus

  On my work's PC (windows 7 32bit) all Adobe Reader and hg Workbench icons on the toolbar (and general shortcuts for hg workbench) are just white pages (with the top left corner folded over). If you right click on the toolbar icon then right click on "TortoiseHg Workbench"(for hg workbench) then "Properties" then the "Change Icon..." button is greyed out (same for "Adobe Reader X"). Also the "Target:" is "TortoiseHg 2.4.0 (x86)" and is greyed out also the "Open File Location" is greyed out. This is the same for both Hg Workbench and Adobe Reader and seems to be the only thing that connects them. I have tried reinstalling to no avail. I also have local admin rights on the PC. I finally I have tried the following following questions without any luck (they aren't quite relevant to my issue but close): Adobe Reader program icon and pdf icons don't appear in Windows 7 Adobe PDF icon disappeared? Encase my description isn't enough to understand the issue here is a screenshot. As you can see the Hg Workbench icon (far left) and a pdf open in Adobe Reader X (second icon to from the left) are both blank and the shortcut is mainly greyed out.

• Is there any advantage/disadvantage to using robots.txt to disallow access to legal pages such as terms, privacy policy, etc.?

  - by CaptainCodeman

  As I understand, having repetitive content is a detriment to search engine placement. Given that many websites that use similar or even identical "Terms and Conditions" and "Privacy Policy" pages due to similar legal wording or due to copy & pasting from the same source, would it be a good idea to disallow access to these pages via robots.txt, in order to avoid being penalized for "non-original content"? Or, on the contrary, could the search engines identify this as circumvention and penalize the site for trying to hide content? Or does it not matter?

• Writing a basic shader for large input files

  - by Zoltan Varadi

  I started writing a shader for my iOS app and instead of starting from scratch i used this tutorial here: http://www.raywenderlich.com/3664/opengl-es-2-0-for-iphone-tutorial I wrote an import function, first to import wavefront .obj models. My problem is that with I can't handle larger inputs (with a simple cube it was working). I realized that the indices array is an array of GLubyte values, which is unsigned char, so as a result i cant have more than 256 indexes. I modified it to GLuint, but then only get a blank screen. What else needs to me modified? p.s.: the source can be downloaded from here: http://d1xzuxjlafny7l.cloudfront.net/downloads/HelloOpenGL.zip

• Windows 7 access denied to executables.. by what?

  - by stijn

  Ever since I started using Windows 7 this problem has been bothering me. From time to time I see similar questions popping up on misc forums, but never did I see an answer. Here are two scenarios that nearly always reproduce it: the explorer way with explorer, navigate to a directory containing at least one exe file go one directory up immediately delete the directory just navigated to yields Folder Acces Denied dialog stating You need permission to perform this action You require permission from Administrators to make changes to this folder, with the buttons try Again and Cancel hitting Try Again never works immediately. Waiting a minute or so and then clickig it again does work note: if in step 2 and waiting a minute or more before going up one directory, the problem does not occur and the folder can be deleted the visual studio way build a project producing an exe file run the executable then close it immediately build the project again (by changing a single character in a source file for example) yields fatal error LNK1168: cannot open /path/to/the.exe for writing note: if in step 2 and waiting a minute or more before building again, the problem does not occur some specs happens both on Windows 7 32 and 64 bit, with VS2008/2010/2011 happens on 3 different machines I do not have a virusscanner of any kind I do have a bunch of services disabled, but nothing that prevents Windows from running normally, UAC is disabled as well happens on any type of disc I always use a user account that is in the Administrators group Obviously both scenarios are very similar and extremely reproducable. So I figured some process must have the file open for some reason, and release it again later. However, using systinternal's handle -a the exe file in question never shows up. (that is the correct way to use handle, right?) So while explorer/VS are reporting they cannot access the file, handle.exe says it's not in use anywhere. This leaves me rather clueless, so I'm wondering if someone can come up with a solution: why does this happen, and how to solve it?

• If all variables are a subset of the superkey, is the database design 5NF? [migrated]

  - by Lukazoid

  I have a table called LogMessages, which has the following columns: Level A numeric value which represents Trace, Debug, Info, Warning, Error or Fatal Time A UTC time Message Foreign key to a Messages table Source Foreign key to a Sources table User Foreign key to a Users table From what I can see, all of these columns are a part of the super key; if any single value differs to an existing row, a new row can be created. My question is, does this design comply to fifth normal form? I am unsure as some groups of data will be repeating, however I don't believe this violates 5NF? (correct me if I'm wrong)

• Programmer logbook application?

  - by jsoldi

  I've just released my application to the public, and I'm working on an updated version, but I really think I should keep track of ALL the code changes. In case some functionality suddenly starts failing, with a history of all the changes I made it would be a lot easier to figure out where I messed it up, in case the problem wasn't already there. The ideal would be to have a super fast computer with a huge hard drive and an application that automatically saves a backup of the whole project every time I change a line in the code, with some file comparison tool that would show me every difference between any two backed up projects, but that's not really possible for now. So, do you know any application that makes it easy for a programmer to keep track of the changes made to the source code?

• Encrypted folders and files stay encrypted when copied

  - by user66126

  Hi all, I just tried out Windows 7 feature to encrypt a folder. I found that when I access the encrypted folder from another computer (the parent folder of the encrypted folder is shared) I can see the files there but I could not open it (which is good). But when I copy the file to another folder outside the encrypted folder (regardless it is on the same remote computer or to the computer from where I am accessing the files) then I can open the file without any problem. This might be how it works ... but that's not what I need. My question is: Can I encrypt a folder (and all files inside), access those files (create, edit) seamlessly while I am logged in normally to the computer ... but make the files stays encrypted when they were copied to another directory outside the encrypted folder? Regardless they were copied to the same computer or another computer or uploaded to a remote server. If this is not a feature that Windows natively support, is there third party software that does that? Thank you.

• Document Map in MS Word 2007 going bonkers

  - by rzlines

  I'm working on a large project report in Microsoft Word 2007 and have been using the document map to generate the index. I have been carefully selecting the headers that need to be added to the document map but I saved the document and opened it up today to work on it - the document map has added whatever it pleases there. This is a temporary fix from a post that I found after extensive searching that works, but when I save and close the document and open it up again I face the same dilemma: I have noticed that when Word stuffs up the document map after opening the file, I can undo this by using the UNDO button. Word calls it ’Autoformat’. I have also fixed a file that has had the document map screwed permanently (i.e saved with it) by selecting all (CTRL+A),selecting the PARAGRAPH drop down menu in the HOME TAB and in the OUTLINE drop down box, selecting ’Body Text’. This removed all the problems and did not seem to affect my outline level paragraph headings. This is also another temporary fix but I have to be on my toes not to let Word auto format at the start of the document. I also can't afford to entirely turn off auto format as I need it. I’ve solved this problem for me. When you open the file, a progress bar at the bottom first says Opening (ESC to Cancel) and then it says Word is formatting the document (ESC to Cancel). If I cancel the second process, TOC fine. No cancelling, TOC screwed. Can anyone work out how to switch off the autoformatting? This is the post in which i found for the temporary fix

• dom0 enable IPv6 for guests

  - by user98651

  I am looking at deploying IPv6 to my virtual machines. Right now I have v6 working great on the dom0 using a 6in4 provided by Hurricane Electric as I do not have native v6. However, I would like to distribute some of the /48 I am receiving to the domUs (/64 per machine would be ideal, but I am open to your suggestions). Static configuration on the domU side is fine. All I want to accomplish is getting the traffic to pass through the dom0 to the domU. To say the least, I'm still trying to wrap my head around all the virtual interfaces and bridges Xen creates. Yes, I have Googled around for this a bit and have not found anything great. I tried using two "vif-route6" bash scripts with no luck (possibly due to my ignorance with Xen networking). I am still stuck (mainly in how to configure the dom0). I would like to imagine this problem is relatively easy to solve and I look forward to your suggestions and help! Edited post to clarify my end goal: getting IPv6 to domU guests. I am completely open to suggestions but am hoping for something other than setting up a tunnel for every guest.

• Scrolling Box2D DebugDraw

  - by onedayitwillmake

  I'm developing a game using Box2D (javascript implementation - Box2DWeb), and I would like to know how I can pan the debug draw. I know the usual answer is - don't use debug draw, it's just for debugging. I'm not, however not all my objects are on the same screen, and i'd like to see where they are in the physics representation. How can I pan the debug drawing? As you can see the debug draw stuff, is show on the top left, but it only shows a small part of the world. Here is an example of what I mean: http://onedayitwillmake.com/ChuClone/ The game is open source, If you'd like to poke through and note something that perhaps i'm doing something that is obviously wrong: https://github.com/onedayitwillmake/ChuClone
