• Confuse with OpenGL, SFML, and its library

  - by Robinson Joaquin

  I am a beginning to enter the world of game development. Lately, I researched that "OPENGL" is one of the tools to use in graphics, then I found out about "SFML" (I think that its a library or something that uses opengl). I am so confuse because all books/ sites said using "GLUT", but many people/fellow developers said that I must use a more updated one like "SFML" but sfml has few/none tutorials. What I am trying to say is "how to create own library or something like your own glut or sfml", and why does opengl has no source code? And how can I use the EXACT(not glut/sfml) opengl in my c++ program? I am so confuse....

• Go passe en version 1.0, le langage de Google est prêt pour être utilisé en production

  Google vient d'annoncer que son langage open source Go était disponible en version 1.0n ce qui marque une importante étape dans l'évolution de ce langage. Rappelons que Go est un langage compilé permettant de simplifier le développement d'applications concurrentes. Il est destiné notamment à la programmation système. Le passage de Go à version 1.0 suppose que le langage soit prêt pour être utilisé en environnement de production et que tout programme créé avec cette version puisse être compilé et exécuté sans modification de code avec les versions suivantes. Toutes les applications s'appuyant sur les versions précédentes doivent être exécutées avec un programme GoFix qui corrigera les problèmes de compatibilité. Avec cette ...

• Is SVN out of style?

  - by jitbit

  It's been only several years since I migrated from Visual Source Safe to SVN. And SVN for me is still kinda "WOW! I can do so many things! SVN is so cool!" But many people around me keep saying "SVN? Really? Meh..." And there's so many of them that I'm worried. Should I move my team to Git / Mercurial or some other fancy thing? I know I sound ridiculous and the obvious answer would be "stay with what works for YOU". SVN does work for me... But every time I create a new project in my repository I keep asking myself - may be this was the time to move? So... Is SVN really that bad? Do I miss a huge opportunity by sticking with it?

• Is acoustic fingerprinting too broad for one audio file only?

  - by IBG

  We were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music. Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms): Always-on app for listening Compare the audio patterns to a single audio file (assume sound is a simple beep) If beep is detected, send notification to server With a flow this simple, do you think acoustic fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start? We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.

• Windows XP hanging on login screen

  - by Nathan W

  I have been given two Eee PC 100HA to manage for some people, they are both running the same hardware and XP home but one is having some strange problems with logging on. The main problem is that it hangs at the login screen for ages and sometimes never gets to the desktop. The strange thing is it only seems to do it after the computer has been cold started, but it won't do it if the computer has been restarted. I have made two logs of the start up with process monitor but every time the logger is attached the computer will log in fine. I have also set the computer to blue screen and create a crash dump when you press ctrl scroll twice but when I do it at the hung login it just sits at a black screen and I don't get a crash dump, I have turned off the auto system restart on failure option also. I can usually fix most computer start up and shutdown problems but this one has got me stuffed. Has anyone had the same problems before, or can recommend something that I can try? Cheers.

• 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 != ' .'

• Corsair Hydro i series cpu cooler fan control

  - by user214690

  Im relatively new at Ubuntu and have found an answer to basically every single issue ive ever had thru this site... Otherthan this. I have been toying with the idea of a Corsair h80i for my dual boot system (win7/U12.10) and mostly use it in ubuntu. I have done some research on the interweb regarding fan control in linux and nearly ran up short untill I came across this thread: http://ubuntuforums.org/archive/index.php/t-2096166.html And it seems to have worked around it. (altho I have not tested it for myself) Is there any program/library/source that can be used to control the fans without having to MacGuyver it??

• How can I port a MonoGame Windows Phone 8 game to iOS?

  - by Homer_Simpson

  I downloaded the trial version of Xamarin Studio and installed it on my iMac. In addition, I installed Xcode on my iMac so that I can use the iPhone emulators in Xamarin Studio. But I don't know how to use my MonoGame Windows Phone 8 source files in a Xamarin iPhone project. How can I use my Windows Phone code in an iPhone project? Can I import all my existing classes(for example Game1.cs) in an iPhone project without changing something? How can I port a MonoGame Windows Phone 8 game to iOS?

• 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?

• 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?

• 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

• Selenium-Nunit Program Structure

  - by Jacobm001

  My office has a suite of web reporting engines written in VB. All in all there's about 300 reports with varying displays depending on the data being input into them. I'm trying to establish an efficient way to deal with such a major diversity, but am struggling with creating a system that won't be a nightmare to code/maintain. What I've considered doing is: On program launch, read the steps required for each test page. This may have multiple tests for the same page with varying inputs. Write each iteration of the test in XML file under $env:temp/testname Use the TestCaseSource attribute of Nunit to funnel every related xml file as a source. My major stumbling block has been how to get that data to the Nunit framework. Is Nunit really appropriate for what I'm trying to do, or is it too static?

• How can I use HAproxy with SSL and get X-Forwarded-For headers AND tell PHP that SSL is in use?

  - by Josh

  I have the following setup: (internet) ---> [ pfSense Box ] /-> [ Apache / PHP server ] [running HAproxy] --+--> [ Apache / PHP server ] +--> [ Apache / PHP server ] \-> [ Apache / PHP server ] For HTTP requests this works great, requests are distributed to my Apache servers just fine. For SSL requests, I had HAproxy distributing the requests using TCP load balancing, and it worked however since HAproxy didn't act as a proxy, it didn't add the X-Forwarded-For HTTP header, and the Apache / PHP servers didn't know the client's real IP address. So, I added stunnel in front of HAproxy, reading that stunnel could add the X-Forwarded-For HTTP header. However, the package which I could install into pfSense does not add this header... also, this apparently kills my ability to use KeepAlive requests, which I would really like to keep. But the biggest issue which killed that idea was that stunnel converted the HTTPS requests into plain HTTP requests, so PHP didn't know that SSL was enabled and tried to redirect to the SSL site. How can I use HAproxy to load balance across a number of SSL servers, allowing those servers to both know the client's IP address and know that SSL is in use? And if possible, how can I do it on my pfSense server? Or should I drop all this and just use nginx?

• Can't start Windows 7 after cloning HDD

  - by Paul

  Brief description: cloned HDD1 - HDD2 HDD1 partition 1 boots HDD1 partition 2 boots HDD2 partition 1 boots HDD2 partition 2 doesn't boot Windows, but is bootable in general Now verbosely: In all the cases computer is the same. I have two Windows 7 installations on HDD1 - both are booting fine. I choose between them using standard Windows 7 boot loader menu. Technically there are 4 partitions: 100 MB Boot loader partition (active), Windows 7 copy 1 (25 GB), Windows 7 copy 2 (150 GB) and Working partition. All are primary. In past few days I tried to clone the whole HDD1 to HDD2 of the same size (but 2,5 inch form factor) as is using Minitool Partition wizard. Everything has been copied, all files are accessible, no faults in file system structure, even boot loader wasn't damaged and I hadn't to repair it. But I can boot only first installation of Windows 7 (it boots without issues). When I choose the second installation, I get immediately a completely black screen without any texts, cursors and other data. HDD isn't accessed after that. This black screen is sensitive to Ctrl-Alt-Delete which causes computer reboot. I did some experimenting: Installed Windows 7 to that partition - it booted fine. Then I renamed "Windows" to "Windows.old" and copied Windows directory from HDD1 as it was, using Far Manager, and got the same troubles - black screen. (Of course I performed renaming and copying from other copy of Windows). So, it seems that problems are inside this installation of Windows, somewhere in its files.

• Why do software patches have to be accepted by a developer?

  - by Nigel

  In open source projects, why do software patches have to be accepted by a developer? Couldn't contributors just release their own patches and allow people to add the patch if they choose to. I'm wondering why there are so many Ubuntu programs that could use such obvious work but aren't updated. For instance, lots of people want Rhythmbox to be more attractive. Why can't the people who design themes on DeviantArt turn those into code and let users download those themes themselves, even if the developers at Rhythmbox won't accept different themes?

• Best choice for 3D Physics Engine for C#/XNA

  - by Nic Foster

  Since 2007 I've been working on the development of an open-source game engine, and have been using JigLibX for 3D Physics. However, the developers on the project have stopped contributing to it for over 2 years now, and it's lacking features I need, or have major bugs in certain features. What are some good choices for 3D physics engines that are written purely in C#? Are there any that are more complete than JigLibX? EDIT: I just stumbled upon an engine called BEPUphysics. It was supported up until May 2012, which is fairly recent. I may check it out, any information that you guys could give on how complete the engine is would be great.

• XRegExp Regular Expression Library for JavaScript

  - by Jan Goyvaerts

  XRegExp is an open source JavaScript library. It extends JavaScript’s regex syntax with features such as free-spacing, named capture, mode modifiers, and Unicode categories, blocks, and scripts. It also provides its own test(), exec(), forEach(), replace(), and split() methods that eliminate most cross-browser inconstencies and bugs. Anyone using non-trivial regexes in their JavaScript code should seriously consider using XRegExp. Last month’s update of the Regular-Expressions.info website added full coverage of XRegExp to the regex tutorial and regex reference sections. But the tools & languages section was missing the XRegExp page, resulting in broken links in the tutorial and reference sections. This page has now been added.

• How to display/define Mirror/Stripping pairs with mdadm

  - by Chris

  I want to make a standard linux software Raid10 over 4 HDD. The server has 4HDDs, 2 pairs from different vendors in order to avoid batch problems. I want to have the mirror over two different Vendors, and then the Stripe over the mirror pairs. I could do that by manually creating Raid1/0, but mdadm supports Raid level 10. I just cant figure out how the Raid10 is then handled and how the data is distributed. mdadm --detail /dev/md10 /dev/md10: Version : 1.2 Creation Time : Wed May 28 11:06:23 2014 Raid Level : raid10 Array Size : 1953260544 (1862.77 GiB 2000.14 GB) Used Dev Size : 976630272 (931.39 GiB 1000.07 GB) Raid Devices : 4 Total Devices : 4 Persistence : Superblock is persistent Update Time : Wed May 28 11:06:23 2014 State : clean, resyncing (PENDING) Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : near=2 Chunk Size : 512K Name : pdwhost:10 (local to host pdwhost) UUID : a3de0ad5:9e694ee1:addc6786:c4449e40 Events : 0 Number Major Minor RaidDevice State 0 8 1 0 active sync /dev/sda1 1 8 81 1 active sync /dev/sdf1 2 8 97 2 active sync /dev/sdg1 3 8 113 3 active sync /dev/sdh1 does not really give any information about that. How it should be: Raid 1 / Mirror over /dev/sda1 /dev/sdf1 and /dev/sdg1 /dev/sdh1 Raid 0 over the two Raid 1 pairs Is it possible to do that with the built in "level=10", how can I see what pairs are mirrored?
