• OT: Airlines and Podcasts

  - by Greg Low

  Those that know me know that I spend an inordinate amount of time on airlines. I also love podcasts, as you can tell from my www.sqldownunder.com site and show. So anything that combines the two is just awesome. Fly With Joe fits that perfectly. Joe D'Eon provides great insights in his show. I was sad last year that he hadn't posted many shows. I've also been quiet for a couple of months (but that's about to change with a bunch of SQL Server 2008 R2 shows). But I've been so pleased that Joe's got...(read more)

• ubuntu 12.04 install black screen

  - by Tara Scarborough

  When I try to install Ubuntu 12.04 i get the grub 1.99 screen that allows me to select ubuntu install, or try ubuntu with out installing. When i select install ubuntu the screen goes black and i can tell the hard drive is running, but there are no on screen prompts. I looked into this problem and attempted to change a few variables by pressing "e" to edit the ubuntu install boot screen I then changed splash to nospash, quiet to noquiet, and add nomodeset at the end of the line that starts with linux before the "--". This still changes nothing when i press F10 to boot. I have tried removing quiet and splash altogether and adding nomodeset, but still to no avail. I am a little frustrated and don't know what to do. Any help would be greatly appreciated! The system is brand new - no OS: Hardware: Zotac ZBOX ZBOX-ID81-PLUS-U Nettop Computer - Intel Celeron 857 1.20 GHz - 8 GB RAM - 320 GB HDD - Intel Graphics Media Accelerator HD Graphics Card

• User Experience Guidance for Developers: Anti-Patterns

  - by ultan o'broin

  Picked this up from a recent Dublin Google Technology User Group meeting: Android App Mistakes: Avoiding the Anti-Patterns by Mark Murphy, CommonsWare Interesting approach of "anti-patterns" aimed at mobile developers (in this case Android), looking at the best way to use code and what's in the SDK while combining it with UX guidance (the premise being the developer does the lot). Interestingly, the idea came through that developers need to stop trying to make one O/S behave like another--on UX grounds. Also, pretty clear that a web-based paradigm is being promoting for Android (translators tell me that translating an Android app reminded them of translating web pages too). Haven't see the "anti"-approach before, developer cookbooks and design patterns sure. Check out the slideshare presentation.

• How to go automatically from Suspend into Hibernate?

  - by Sergey Stadnik

  Is it possible to make Ubuntu go into Hibernate state from Suspend, aka "Suspend Sedation"? For example, my laptop is set up to go into a Suspend once I close the lid. If then I don't use it for entire day, the battery goes flat, because even in suspend mode the hardware still consumes a small amount of power, and the battery eventually discharges. What I want is to be able to tell Ubuntu that even if it is suspended, it still needs to go into Hibernate after some hours of inactivity. Windows can do that. Ubuntu can be programmed to go into Standby or Hibernate on timer, but not both. Update: I guess I need to be more specific. What I am looking for is this: When I close the lid, the laptop is put into Suspend. Then, after a pre-determined time (even if the battery is going strong) if I still don't use it, it should put itself into a Hibernate to save battery power.

• Slick and Timers?

  - by user3491043

  I'm making a game where I need events to happen in a precise amount of time. Explanation : I want that event A happens at 12000ms, and event B happens every 10000ms. So "if"s should looks like this. //event A if(Ticks == 12000) //do things //even B if(Ticks % 10000 == 0) //do stuff But now how can I have this "Ticks" value ? I tried to declare an int and then increasing it in the update method, I tried 2 ways of increasing it : Ticks++; It doesn't works because the update method is not always called every microseconds. Ticks += delta; It's kinda good but the delta is not always equals to 1, so I can miss the precise values I need in the if statements So if you know how can I do events in a precise amount of time please tell me how can I do this

• C# books for the experienced programmer

  - by Michael Dmitry Azarkevich

  So I've been programming in C# for 3 years now (been programming in various languages for 3 years before that as well) and most of the stuff I learned I pieced together on the internet. The thing is, I want to understand C# more formally and in depth and so would like to get some books on the subjects. Any books you'd recommend? Also, I've heard good things about "C# 4.0 in a Nutshell", "Pro C# 2010 and the .NET 4 Platform" and "CLR via C#". What do you think of these? (The people at stackoverflow told me to take it here. Please, Please tell me I'm in the right place this time)

• My Lightning Talk in MP3 format

  - by Rob Farley

  Download it now via http://bit.ly/RFCollation  Lots of people tell me they wish they’d heard my Lightning Talk from the PASS Summit. This was the one that was five minutes, in which I explained Collation using examples comparing US English, UK English and Australian English. At the end, I showed my Arsenal thongs. You can see a picture of them below. There was a visual joke involving the name Arsenal too... After the recordings became available, I asked the PASS legal people, and they said I could do what I liked with my own five-minute set, so long as I didn’t sell it. So I made an MP3. I’ve uploaded it to the LobsterPot Solutions web server, and provided an easy link via http://bit.ly/RFCollation. It’s a link straight to the MP3, and you’re welcome to download it, put it on your iPod, whatever you like. And also feel free to write comments here, to let me know what you think.

• Send arbitrary commands to modem for info

  - by mydoghasworms

  I have a USB 3G data card and modem. According to the supplier, to check the data balance on the account, I must dial a number like *89# (or whatever) from the handset. The device appears as a ppp0 interface in my network devices. How does one go about issuing commands to the modem to send the commands and receive back the information? UPDATE: OK, I found some help here: http://www.linuxquestions.org/questions/linux-hardware-18/sending-at-commands-to-a-sms-modem-372445/, but firstly, there are 3 ttyUSB devices on my system, and I assume that one of them is the 3G modem, but how can I tell? Secondly, trying to echo something to two of them says that the device is busy, which stands to reason, because I am using it to connect to the internet. Some help, please?

• My Mix10 coup de coeur

  - by guybarrette

  If you ask me what was my Mix10 coup de coeur, I’d have to say Bill Buxton.  I was privileged to spend an hour an a half in a small room with about twelve people and Bill Buxton.  This man has such a incredible background and he is so inspiring.  You could really tell that he is a researcher because as he was talking about something, you could see him thinking about something else and trying at the same time to cross reference that. Here’s a list of videos recorded at Mix.  The first one is the shortest one at 9 minutes.

What I want to do is the following: I have a single webpage for example: MYWEBPAGEdotCOM/INDEX.HTML that will always look the same, except for one link on the page. the link would be on the page for example: LINK TO AFFILIATE: affiliatedotCOM/my-affiliate_code_here_DYNAMIC_REFERER the only thing would change is the "DYNAMIC_REFERER" with every dynamic url on this page: MYWEBPAGEdotCOM/INDEX.PHP_id=test1 MYWEBPAGEdotCOM/INDEX.PHP_id=test2 MYWEBPAGEdotCOM/INDEX.PHP_id=test3 MYWEBPAGEdotCOM/INDEX.PHP_id=test4 which would only hange the dynamic link on the page to: affiliatedotCOM/my-affiliate_code_here_test1 affiliatedotCOM/my-affiliate_code_here_test2 affiliatedotCOM/my-affiliate_code_here_test3 affiliatedotCOM/my-affiliate_code_here_test4 Can someone tell me how I could go about doing this?

• Playing Blu-ray using VLC

  - by Kevin

  I've been searching for a way to play Blu-ray using VLC on Ubuntu 12.04 64bit and all of them tell me that I've to somehow rip the disk into .mkv format then play it. But today, I found a page with directions on how to play Blu-rays directly on VLC. I've already finished downloading and pasting the files it told me to do, But it didn't work for me. Then I found a page where someone had tried it and it worked for them. Does anyone know how they got it to work? The page with the directions. The page where it worked. I also found this Does anyone know what it is talking about? I've already downloaded lxBDplayer, but I encountered a problem when installing the lcbdaacs plugins. Are there any other ways to install the lxbdaacs plugin?

• How can I start the right way from the beginning in learning web development?

  - by Steve

  Well, I know I have to learn many things such as HTML, JavaScript, CSS, PHP, ASP.NET, SQL, etc. However, I don't know if I start, for example, learning ASP.NET before I learn HTML and CSS then would I say in the near future that it was better for me if i start learning another thing earlier so I don't need to come back and learn it now! You guys, who have the experience in web development, know after you have reached what you are now how should the right start be! So, can you tell me how?

• GPL the Dark Side

  - by EmbeddedInsider

  This blog is about the GPL Issues nobody talks about.  Its about the evil inherent in the GPL License. Evil?  But did not someone tell us that "open" is good?  Well, yes, and I might agree. It just depends on what we mean by 'open'.   There are many kinds of 'open' license, and many of these I like.  But  I maintain the GPL; the principle license of the Open Source Software Foundation, is most certainly NOT open for business.  And to the extent that software is conceived, developed, and maintained business, not hobbyists, the GPL is very, very evil. Controversial? You bet.  Flame away please. Lawrence Ricci www.EmbeddedInsider.com

• 12.04 - Connecting Acer X203H monitor to new Dell XPS 15z laptop

  - by Lucy Dixon

  I have installed the latest version of Ubuntu (12.04) on my boyfriend's new Dell XPS 15z laptop. He uses a Microsoft wireless keyboard and mouse, and an Acer X203H monitor with his set-up. No problems with the keyboard or mouse, or with connecting the HP printer, but we just can't get the laptop to talk to the Acer monitor. With his old setup he used a VGA cable to connect machine & monitor. New laptop has no VGA port, but we've bought a VGA to HDMI adaptor to connect to the laptop. Have tried using Fn F2 to change the display from laptop to monitor, but it doesn't see the monitor at all. HELP! Is there a driver I can install from somewhere? Or how can I tell Ubuntu to look for the monitor on another port? Completely in the dark, and about to get in trouble!! Thanks

• Nautilus will not launch after update to 12.10

  - by dereksalerno

  I updated to Ubuntu 12.10 today from 12.04 using the graphical update tool. Everything seemed to be fine until I went to open Nautilus, and it would not open. Bizarrely, I am able to open a file that I happen to have on my desktop, but when I click on the launcher, it never opens. When I enter 'nautilus' in the terminal, I get this: (nautilus:8557): Gdk-CRITICAL **: gdk_x11_display_get_xdisplay: assertion `GDK_IS_DISPLAY (display)' failed zsh: segmentation fault (core dumped) nautilus I am not a total novice with ubuntu or linux, but all I can tell is that there is some problem with X. Can someone please point me in the right direction as far as fixing this? I really don't want to have to do a fresh install. Thank you very much.

• How to make "xset s off" survive a reboot (12.04)

  - by matteo

  On an almost-fresh install of Ubuntu 12.04, after disabling screen turning off, screen lock, and suspension on inactivity from all the (two) places one can find under Ubuntu's System Settings, the screen still turns black after some minutes of inactivity. I can't tell for sure whether it only becomes blank/black or turns off. I've uninstalled gnome-screensaver, which didn't change anything. Of the several answers I found out there (most of which I didn't try because they were either unclear or reported to not work for everybody), I tried one that DID work: sudo xset s off after which I left the computer unattended for hours and the screen never turned black, so it definitely worked. HOWEVER it does not survive a reboot. After reboot, screen starts turning black again after N minutes of inactivity. Given that "xset s off" does work until reboot, how do I make that setting permanent? I guess I could create a script that runs at startup issuing that command, but I think that would be a horrible hack and there should be a cleaner way to accomplish this.
