• Ubuntu 12.10 AMD/Intel Hybrid Graphics not working

  - by Marian Lux

  On Ubuntu 12.04 my Sony Vaio VPCSE with Intel® HD Graphics 3000 and AMD Radeon™ HD 6630M worked fine with the Catalyst Control Center version 12.6. Also the switching between integrated and discrete graphic card was working. In both cases, I followed this tutorial. But it is not working on Ubuntu 12.10. I tested the tutorial with the Catalyst Control Center from the Ubuntu Software Center, the version 12.8 and version 12.9. Always the same problem: After installation process I am able to boot in the login-screen. But after entering the password for my username, only the background-image appears. Unity seems not to be starting. I am only able to reach the context-menu by right clicking the mouse button. I also tried his fix, but is also does not work for me. Any ideas what to do to fix this problem?

• Java 8 for Tablets, Pis, and Legos at Silicon Valley JUG - 8/20/2014

  - by hinkmond

  A bunch of people attended the Silicon Valley Java Users Group meeting last night and saw Stephen Chin talk about "Java 8 for Tablets, Pis, and Legos". I was there and thought Stephen's presentation and demos were very cool as always. Here are some photos (mostly taken by Arun) from last night. See: Photos from SV JUG 8/20/2014 The most interesting combination of the topics from last night (to me at least) is to combine Lambdas from Java SE Embedded 8 with running on an embedded device like the Raspberry Pi, or even better on an i.MX6 target device with a quad-core processor. Lambdas and Embedded, now that's a cool combo... Hinkmond

• How do I reset my Ubuntu 12.10 password?

  - by Salvador Yniguez

  So my sister gave me this old laptop that has Ubuntu 12.10. The problem is that she has a username administrator password, but she forgot it. I've tried using GRUB and launching recovery mode and using the root shell prompt. And I type the "passwd username" command, and it tells me to type the new UNIX password, but when I try to type a new password it's like my keyboard doesn't even work. It types nothing. What's the problem? Why does my keyboard not type anything when I try to reset the UNIX password? It always works perfectly fine. I'm grateful for any help, thank you.

• Unmounted disk still spins up regularly

  - by Erik Johansson

  I just added a disk, with partitions but none of them are mounted. The disk will still spin up every now and then. it goes like this: ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.37.08 CET ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.46.12 CET Also it always spins up when I shut down the computer. Any tips are welcome, e.g. how can I figure out which process is accessing the disk, are there any daemons doing this? I know it isn't a cron job.

• Is there a phrase or word to describe an algorithim or programme is complete in that given any value for its arguments there is a predictable outcome?

  - by Mrk Mnl

  Is there a phrase to describe an algorithim or programme is complete in that given any possible value for its arguments there is a predicatable outcome? i.e. all the ramifications have been considered whatever the context? A simple example would be the below function: function returns string get_item_type(int type_no) { if(type_no < 10) return "hockey stick" else if (type_no < 20) return "bulldozer" else return "unknown" } (excuse the dismal pseudo code) No matter what number is supplied all possibiblites are catered for. My question is: is there a word to fill the blank here: "get_item_type() is ______ complete" ? (The answer is not Turing Complete - that is something quite different - but I annoyingly always think of something as "Turing Complete" when I am thinking of the above).

• DBMS agnostic - What to name the COUNT column from a SQL Query

  - by cyberkiwi

  I have trouble naming the COUNT() column from SQL queries and will swap between various variants _Count [Count] (sql, or "count" or backticks for MySQL etc) C Cnt CountSomething (where "something" is the field being counted, or "CountAll") NoOfRows RowCount etc Has anyone come up with any name that you are happy with and always use without hesitation? This is bothering me because after joining SO just recently, my answers have shown this tendency of flip-flopping with no consistency. I need to get this sorted. Please help. (While we're at it, what do you use for SUM etc?) Note: Before you close this question, consider that this one was not: What's the best name for a non-mutating “add” method on an immutable collection?

• Did Blowing Into Nintendo Cartridges Really Help?

  - by Jason Fitzpatrick

  Anyone old enough to remember playing cartridge-based games like those that came with the Nintendo Entertainment System or its successors certainly remembers how blowing across the cartridge opening always seemed to help a stubborn game load–but did blowing on them really help? Mental Floss shares the results of their fact finding mission, a mission that included researching the connection mechanism in the NES, talking to Frank Viturello (who conducted an informal study on the effects of moisture on cartridge connectors), and otherwise delving into the history of the phenomenon. The most interesting part of the analysis, by far, is their explanation of how blowing on the cartridge didn’t do anything but the ritual of removing the cartridge to blow on it did. Hit up the link below for the full story. Did Blowing into Nintendo Cartridges Really Help?

• Future of a ServiceStack based Solution in the Context of Licensing

  - by Harindaka

  I just want someone to clarify the following questions as Demis Bellot had announced a couple of weeks ago that ServiceStack would go commercial. Refer link below. https://plus.google.com/app/basic/stream/z12tfvoackvnx1xzd04cfrirpvybu1nje54 (Please note that when I say ServiceStack or SS I refer to all associated SS libraries such as ServiceStack.Text, etc.) If I have a solution already developed using ServiceStack today will I have to purchase a license once SS goes commercial even if I don't upgrade the SS binaries to the commercial release version? Will previous versions of SS (prior to commercial licensing) always be opensource and use the same license as before? If I fork SS today (prior to commercial licensing) on Github, would it be illegal to maintain that after SS goes commercial? If the answer to question 2 is yes, then would I still be able to fork a previous version after SS goes commercial without worrying about the commercial license (all the while maintaining and releasing the source to the public)?

• Why not expose a primary key

  - by Angelo Neuschitzer

  In my education I have been told that it is a flawed idea to expose actual primary keys (not only DB keys, but all primary accessors) to the user. I always thought it to be a security problem (because an attacker could attempt to read stuff not their own). Now I have to check if the user is allowed to access anyway, so is there a different reason behind it? Also, as my users have to access the data anyway I will need to have a public key for the outside world somewhere in between. Now that public key has the same problems as the primary key, doesn't it?

• KDE Sometimes Glitches On Wakeup

  - by Mew

  Well, a picture is work 1k words: Looks bad, huh? I am using the 331-updates latest 331.67 drivers from NVidia's website on a Dell Latitude e6400. Everything else is up-to-date. This only happens when I resume from sleep, or I switch to a VT and back. It also doesn't ALWAYS happen, which I find odd. Graphics Card: Nvidia Quadro NVS160M UPDATE AFTER TESTING: This problem only exists with KDE (specifically QT). I can go into Unity or Mint or any non QT-based GUI and it works perfectly with no resume errors. UPDATE: This only happens when I use KWin (and KDE). I have upgraded to 14.04 and the problem is not occurring as frequently. Also, sometimes this effect doesn't happen, but instead the top menu bar simply goes out of focus with the rest of the screen goes blank.

• Are too many assertions code smell?

  - by Florents

  I've really fallen in love with unit testing and TDD - I am test infected. However, unit testing is used for public methods. Sometimes though I do have to test some assumptions-assertions in private methods too, because some of them are "dangerous" and refactoring can't help further. (I know, testing frameworks allo testing private methods). So, It became a habit of mine that (almost always) the first and the last line of a private method are both assertions. I guess this couldn't be bad (right ??). However, I've noticed that I also tend to use assertions in public methods too (as in the private) just "to be sure". Could this be "testing duplication" since the public method assumpotions are tested from the unit testng framework? Could someone think of too many assertions as a code smell?

• Checker AI in visual basic not working [on hold]

  - by Eugene Galkine

  I am trying to a make checkers in visual basic with ai. I am using the minimax algorithm (or at least what I understand of it) and it works, except the ai is retarded and plays like it is trying to loose and I tried to switch around the min and the max but the results are IDENTICAL. I am pissed of and have been trying to fix it for over a week now, I would really appreciate it if someone could help me out here. I have 3 years experience of programming (in Java, only about of month of VB experience) and I always am able to solve all my errors on my own so I don't know why I can't get this to work. The program is not at all optimized or anything at this point and is over 1.2K lines long, so here is the entire vb project instead: https://www.dropbox.com/sh/evii0jendn93ir2/9fntwH2dNW I would really appreciate any help I could get.

• What are basic programming directions? [closed]

  - by Goward Gerald

  What are basic programming directions? Can you please list them and give a brief review of each? Would be nice to have a list for each direction (web-development/*enterprise*/standalone/*mobile*/etc, correct me if I skipped something) like this: 1). Most popular languages of this direction (php for web, objective C for iOS mobile development etc) 2). It's demand on market (from 0 to 5, subjective) 3). How much tasks differ (do you always create same-of-a-kind programs which are like clones of each oother or projects change and you often get to create something interesting, new and fresh?) 4). Freelance demand (from 0 to 5) 5). Fun factor (from 0 to 5, totally subjective but still write it please) Thanks!

• Which is more valuable in product development: an action-oriented or visionary bent?

  - by Marc

  As a software development professional in a fairly conservative large-firm, I always had a much more action-oriented bent, as my job was fairly stable and all that mattered was doing as I was told and completing tasks that were germane to the career of a benevolent dictator (i.e., my boss' boss). Now that I'm no longer working for "the Man", I find it just as important to use the left side of my brain and wrap my head around this whole "vision thing". Which do you think is more important for software product development in a small, yet feisty start-up: Knowing the path or walking (or running) it?

• LibreOffice: Open in current program by default?

  - by David Oneill

  I often need to open pipe delimited .txt files in LibreOffice Calc. However, once I have Calc running, if I do File Open and select a spreadsheet with the extension .txt, it opens it in Writer instead. Is there a way to tell the file I'm trying to open using whatever program instead of trying to pick which one to use? Barring that, is there a way I tell it to always use Calc for .txt files (when I open them from the open dialog in Calc)? I still want them to open in GEdit like they currently do if I double click them from Thunar.

• Android/Java AI agent framework/middleware

  - by corneliu

  I am looking for an AI agent framework to use as a starting point in an Android game I have to create for a university research project. It has been suggested to me to use JADE, but, as far as I can tell, it's not a suitable framework for games (at least for my game idea) because it runs in a split-execution mode, and it needs an always-active network connection to a main host. What I want is just a little something to give me a headstart. I am willing to adjust the game's features to the framework because it's more of a mockup game, and the purpose is to compare the performance of a couple of agents in the game world. The game will be very simplistic, with a minimal UI that displays various stats about the characters in the game (so no graphics, no pathfinding). Thank you.

• How and where do you store your private work/source codes?

  - by Amir Rezaei

  I have worked as developer for over 10 years now. Over the time I have had my own small projects where I have developed tool/application and games. I have not found any robust solution to store my work. It’s always fun to get back to your code and see how you did before and how you would do it now. It’s just a work that is unfortunate to get lost. There are SVN solution such as Google’s Project Hosting. However I’m not interested in sharing my code or making it open source. Currently I’m hosting my own SVN server. So here comes my question. How and where do you store your private work/source codes? Requirements: Source code versioning Backup Prefers free

• Will small random dynamic snippets break caching

  - by Saif Bechan

  I am busy writing a WordPress plugin. Now most users have cache plugins installed, they cache the pages. I know also some webservers as nginx have php caching and whatnot. There are also things like memcached. Now I have to admit I do not know exactly how they work, if anyone have some good links on how they work I would be glad. Some links where it's explained simple, not to technical. Now the question. My plugin displays different statistics on posts, they are always different, will this break the caching of the page. To take is a step further, sometimes the statistics of the post needs updating, and there is a small javascript snippet added to the page. Now will these two action result in the page not caching, or am I ok.

• Tripple boot install with Windows MBR

  - by Andre Doria

  I have 2 hard drives, each 1TB. First drive has only Windows 7. The second drive has Kali installed on logical partitions #5 (/boot), #6 (/), #7 (/home), and #8 (swap). The bootloader is installed in /dev/sdb5. It also has Ubuntu installed on logical partitions #9 (/boot), #10 (/), #11 (/home), and #12 (swap). I want to use Windows bootloader, so I use easyBCD to configure the boot menu. EasyBCD sees my second drive partitions as #1, #2, #3,..., #8. I then add Kali selecting second drive #1 (/boot) partition, and Ubuntu selecting its #5 (/boot) partition. After this my menu has choices of Windows 7 (default), Kali, and Ubuntu. The problem is that whether I select Kali or Ubuntu I always boot Kali! Any idea on how to enable Ubuntu boot while also keep using Windows bootloader in MBR?

• What is the advantage of a programmers VM apart from portability

  - by user619818

  I can understand the benefits of Java running on a JVM. Portability. Nice simple reason. But I have always been puzzled as to why Microsoft brought out their own version of a JVM - .NET. C# is supposed to be a fine language (haven't used myself) but could Microsoft have launched product to use native. ie to generate an exe? My colleague is learning F#. The reason it has to be a language which runs on .NET is because the Microsoft Lync API which will be used is only available on .NET. ie there is no C API for Lync. A cynical view may be that the reason is vendor lockin. F# will only run on a Microsoft platform (or C# for that matter) and so program is locked in. But maybe I am missing some other benefit of a VM platform?
