• Why are many programmers moving their code to github?

  - by Chibueze Opata

  For the past 6 months or more, I've been seeing many codes hosted at sourceforge.net as well as other hosting sites "Move to GitHub". A mere Google Search with the phrase "Moved to Github" returns several results containing the text moved to github. This is very confusing for me, and I'm wondering, why exactly are people moving? Does it mean that GitHub is better or is there some special advantage I'm not seeing?

• GUI keyword confusion

  - by richzilla

  Ive been using linux for some time, and ive never quite got my head around the various keywords attached to the GUI. I think i understand the difference between the likes of KDE and Gnome - They are collections of applications and other software that make up a given gui environment. However a quick read through any vaguely technical linux websites will reveal terms like: Murrine Clearlooks GTK Beryl Metacity Window manager Which if im honest, i have no real idea what they mean and how they all relate to each other. Can anybody clarify?

• Side effect-free interface on top of a stateful library

  - by beta

  In an interview with John Hughes where he talks about Erlang and Haskell, he has the following to say about using stateful libraries in Erlang: If I want to use a stateful library, I usually build a side effect-free interface on top of it so that I can the use it safely in the rest of my code. What does he mean by this? I am trying to think of an example of how this would look, but my imagination and/or knowledge is failing me.

• Did You Know? I gave two presentations last week

  - by Kalen Delaney

  Even though I didn't make it to TechEd this year, it didn't mean I was quiet last week. On Wednesday, I was in Colorado, giving a talk for the new Colorado PASS User Group, which is a joint venture between 3 different existing groups from Colorado Springs, Denver and Boulder. On Saturday, I spoke at SQL Saturday #43, in Redmond on the Microsoft campus. My presence there has already been mentioned on two other blogs here at SQLBlog: Merrill Aldrich and the infamous Buck Woody . As Merrill mentioned,...(read more)

• Geek City: Preparing for the SQL Server Master Exam

  - by Kalen Delaney

  I was amazed at the results when I just did a search of SQLBlog, and realized no one had really blogged here about the changes to the Microsoft Certified Master (MCM) program. Greg Low described the MCM program when he decided to pursue the MCM at the end of 2008, but two years later, at the end of 2010, Microsoft completely changed the requirements. Microsoft published the new requirements here . The three week intensive course is no longer required, but that doesn't mean you can just buy an exam...(read more)

• How does it matter if a character is 8 bit or 16 bit or 32 bit

  - by vin

  Well, I am reading Programing Windows with MFC, and I came across Unicode and ASCII code characters. I understood the point of using Unicode over ASCII, but what I do not get is how and why is it important to use 8bit/16bit/32bit character? What good does it do to the system? How does the processing of the operating system differ for different bits of character. My question here is, what does it mean to a character when it is a x-bit character?

• Are there specific legal issues for web developers working on sex dating sites?

  - by YumYumYum

  Say I have created many ordinary websites which are not related to any dating/sexual content. Are the rules and regulations for a developer the same when making a sex-related dating site? I'm talking about a site where people meet together and get to know each other, with the intent of having a sexual relationship (you know what I mean), also featuring webcam sex, but not explicitly a porno site. Do such sites have any special legal issues for developers compared with non-sexual/dating sites?

• Instruction vs data cache usage

  - by Nick Rosencrantz

  Say I've got a cache memory where instruction and data have different cache memories ("Harvard architecture"). Which cache, instruction or data, is used most often? I mean "most often" as in time, not amount of data since data memory might be used "more" in terms of amount of data while instruction cache might be used "more often" especially depending on the program. Are there different answers a) in general and b) for a specific program?

• Is "Interface inheritance" always safe?

  - by Software Engeneering Learner

  I'm reading "Effective Java" by Josh Bloch and in there is Item 16 where he tells how to use inheritance in a correct way and by inheritance he means only class inheritance, not implementing interfaces or extend interfaces by other interfaces. I didn't find any mention of interface inheritance in the entire book. Does this mean that interface inheritance is always safe? Or there are guidlines for interface inheritance?

• How to check SERP position correctly?

  - by Cengiz Frostclaw

  I wonder how do you check your website's SERP position for a certain query. I cannot directly go to Google and search, because it knows i'm looking for my site, and it shows it in the first position, but from another browser, it cannot be even in the first page. So how do you check for "average user" ? I use Tor browser for that, since it gives me a completely different IP, do you think is it safe? I mean, does it give useful information ?

  I've set up my user account so that no password is required to login and I need to install some updates. However when prompted for the password, it says authentication failed if I leave the box blank. I don't have a password, how am I supposed to authenticate? EDIT I tried the method in Reset lost administrative(root) password but it came out with an error: Authentication token manipulation error password unchanged. What does this mean?

• Is it possible to use Python with the Ubuntu SDK?

  - by Zignd

  David Planella wrote in his answer to a question I posted that: ...the recommended way to develop apps for Ubuntu is the Ubuntu SDK. So I installed it, but looks like the supported programming language is C++. Does it mean I will need to know C++ to develop a new application for Ubuntu? Is C++ the recommended programming language for Ubuntu application now? What about Python, I started learning it hoping to develop applications for Ubuntu.

• Stuff you should have learned in school but didn't pay attention to at the time

  - by HLGEM

  This question made me think that there was a better question to ask. What did you learn in school that you didn't care about at the time, but turned out to be useful or you had to relearn in the workplace because you had it in school, but didn't retain the information and you needed it? (I mean for software related jobs.) I think this might help college students identify some of what they really should be paying attention to while they are in school.

• [New England] SQL Saturday 71 - April 2 - Boston Area

  - by Adam Machanic

  April in the Boston area means many things. The Boston Marathon, the beginning of baseball season, and -- hopefully -- a bit of a respite from the ridiculously cold and snowy winter we've been having. This April will mean one more thing: A full-day, free SQL Server event featuring 30 top-notch sessions . SQL Saturday 71 will be the third full-day event in the area in as many years, and is shaping up to be the best yet. For the past several months I've been working and planning in conjunction with...(read more)

• Checking media [Fail] on boot

  - by karolsojko

  Lately I've been getting this black screen at boot time with 2 lines saying Checking media [Fail] And the time of booting has extended greatly due to that thing (like from seconds to a minute) I have a Dell XPS15 with SSD and I'm running Ubuntu 12.10 and it was not like this before. I don't have a clue what is it connected with - maybe it's due to a kernel update or something. And what do those 2 lines mean.

• Can I instruct the browser not to look for a favicon?

  - by Peter Boughton

  I have a website that doesn't have/need a favicon. Is there a way to instruct the browser not to waste a request looking for /favicon.ico ? I don't mean filtering logs, but something client-side, like this: <link rel="shortcut icon" href="about:blank" /> That appears to work, but I'm not in a position to do comprehensive tests, (and search engines are being unhelpful). Can anyone confirm if this is a valid method, or provide a suitable alternative?

• Android game development in c++

  - by kamziro

  So being a primarily c/c++ developer, I've always thought that the only option for mobile game development for me was using iOS, which allows for c/c++ (and minimising objective C). I heard from a friend though, that android has a native development toolkit which allows for c++ code to work on android. Has anyone used this, and if so, how do you find it? I mean, will it "just work" like iOS, or are there more considerations that need to be taken care of due to the wide variety of android devices available?
