• Ubuntu boots to black screen after failed upgrade from 12.04 to 12.10

  - by ywx

  This happened when I tried to upgrade from 12.04 to 12.10. I don't know whether the upgrade process had completed downloading and installing packages or whether it was still in progress, but I got a message The application Compiz has closed unexpectedly. At that point, my mouse stopped working so I switched to tty1 by Ctrl+Alt+F1 and rebooted from there. I then found that I could not boot into Ubuntu any more. My screen stayed first purple then black. I went back to tty1 and it said I was running 12.10. I tried some suggestions in this thread on Ubuntuforums: Wubi blank purple screen than blank black screen and this one: How to set NOMODESET and other kernel boot options in grub2 but nothing seemed to work. I can boot Windows as normal. I am using Wubi on Windows7. My laptop is a Lenovo T410i with NVIDA NVS 3100m

• Optimizing data downloaded via 'link' media queries and asynchronous loading

  - by adam-asdf

  I have a website that tries to make sensible use of media queries and avoid 'expensive' CSS for users of mobile devices. My eventual goal is to make it 'mobile-first' but for now, since it is based on Twitter Bootstrap it isn't. I included some background images (Base64 encoded) and styles that would only apply to "full-size" browsers in a separate stylesheet loaded asynchronously via modernizr.load. In Firefox (but not webkit browsers) it makes it so that if you navigate away from the homepage and then return, the content (specifically, all those extras) 'blinks' when it finishes loading...or maybe I should say reloading. If, instead of using modernizr.load, I include that stylesheet via a link... in the head with a media query attribute will it prevent the data from being downloaded by non-matching browsers (mobile, based on screensize) that it is inapplicable to?

• Keyboard Mouse Problem

  - by Zachary K

  I just installed Ubuntu on my laptop (Core 2 Duo Sony Vaio) and am having a problem with the external keyboard and mouse. When I first logged in the left mouse button does not work, this can be solved by unplugging the external keyboard/mouse's USB connector and then plugging it back in again. But Then randomly other problems happen. (Shift gets stuck, keys don't work etc) The keyboard and mouse are a generic brand wireless (A4 Tech) that I got for cheap. Both work OK under windows so this is a major pain.

• Text reverses on remote gnome session

  - by Andrew Stern

  I have two computers running 10.4 . The first machine is a wired desktop with sshd. The second is a wifi connected laptop with the ssh client. When I use my laptop to bring up a remote gnome session to my desktop all the text gets reversed. Steps: 1) login as a user on the laptop to activate the wifi with a stored key. 2) goto a console Ctrl-Alt F1 3) do a xterm -- :1 to bring up a blank graphic session 4) ssh -Y user@desktopmachine gnome-session This shows reversed text and messes up the keyboard so I can't type

• where to define variable for a for each loop?

  - by David

  can you please advise me why my first code attempt didn't work : public void listAllFiles() { for(String filename : files) { int position = 0; System.out.println(position + ": " + filename); position = position + 1; } } it kept printing position at 0 without iterating position but it seems to work after i did it this way: public void listAllFiles() { int position = 0; for(String filename : files) { System.out.println(position + ": " + filename); position = position + 1; } } I don't understand why the position + 1 was not being executed, is it because we are not meant to define variables inside for loops or am i missing something in my code.

• What Is The Relationship Between Software Architect and Team Member

  - by Steve Peng

  I work for a small company which has less than 100 persons. Several months ago, this company offered me position of SA and I accepted. There are three teams in this company, and I work for one of them. This is the first time I work as a SA. During the past months, I find I don't have any power of management, I even can't let the team member do things (coding-related) in the way which is correct and more efficient. The team members argue with me on very very basic technical questions and I have to explain to them again and again. Though some members did take my advice, other members stubbornly program in their way which frequently proved wrong finally. Recently I feel a little tired and confused. I wonder what is correct relationship between a Software Architect and team members including the team leader? Besides, is software architect also leaded by the Team Leader?

• DDDSouthWest 4.0 26th May 2012 - Async 20/20 presentation

  - by Liam Westley

  As I wasn’t voted in with my nominated sessions I presented a 20/20 talk on the new async functionality coming with the .Net Framework.  This was based on the PechaKucha presentation format, where you have only 20 slides with only 20 seconds per slide, and it progresses automatically. It was the first I’d attempted, so thanks to the organisers for allowing me to have a go. Although creating the slide deck was definitely easier than a one hour presentation, it was much more stressful giving the talk by the end of the 6m 40s. I’m not going to upload the slide deck (it won’t make much sense) but I did record the audio and used the excellent Camtasia to create a video of the slide deck with that audio which you can watch over here, https://vimeo.com/42957952

• Why was my Facebook game rejected with the note that "your app icon must not overlap with content in your cover image?"

  - by peterwilli

  My FB game just recently got rejected for two reasons. The first I fixed, but I just can't see to figure out what they mean by the second, and I was hoping someone else got the same issue and did know what they meant. The remaining error is: Cover Image Your app icon must not overlap with content in your cover image. Click on 'Web Preview' in the 'App Details' section to check for overlap prior to submitting your app. See more here. All I know is that the rejection has something to do with the cover image, not the icons or the screenshots. The web preview of my game looks like this now: Please let me know what to do to get approved.

• Are log records removed from ldf file for rollbacks?

  - by TiborKaraszi

  Seems like a simple enough question, right? This question (but more targeted, read on) was raised in an MCT forum. While the discussion was on-going and and I tried to come up with answers, I realized that this question are really several questions. First, what is a rollback? I can see three different types of rollbacks (there might be more, of course): Regular rollback, as in ROLLBACK TRAN (or lost/terminated connection) Rollback done by restore recovery. I.e., end-time of backup included some transaciton...(read more)

• User generated content: a basic yet simple to use OR a complex yet powerful solution?

  - by ne5tebiu

  As stated above, which solution is better for a game based on user generated content? The simple solution (in-game editor) is great for gamers without experience in coding and etc. In this way every player could populate the game with content. But the content would be very limited. The complex solution would allow the content to be with almost no limitation but casual gamers probably couldn't make hardly any content at all. If both solutions are used, the quality behind the second solution would be more valuable than the first solution's quantity. However, making a powerful in-game editor could even take more time and manpower than the actual game and every gamer would have to learn how to use the new complex tool, understand it, and master it if he or she wants to make quality content.

• Given a RGB color x, how to find the most contrasting color y?

  - by Arthur Wulf White

  I have to mark a certain item in a way that will make it stick-out in the background. I need it to be surrounded with the color that contrasts the background as much as possible so it will pop out and easily noticeable by the player. Lets say I know the background is color 'x', how do I find 'y' such that it will be very contrasting to 'x' and easy to notice in a background where 'x' is a dominant color? I first thought about inverting color 'x' and then I noticed that when 'x' is a medium shade of gray, if I invert 'x' to get 'y', then 'y' is also a medium shade of gray which does not work.

• Did You Know? More online seminars!

  - by Kalen Delaney

  I am in Tucson again, having just recorded two more online workshops to be broadcast by SSWUG. We haven't set the dates yet, but we are thinking about offering a special package deal for the two of them. The topics really are related and I think they would work well together. They are both on aspects of Query Processing. The first was on how to interpret Query Plans and is an introduction to the topic. However, it only includes a discussion of how SQL Server actually processes your queries. For example,...(read more)

• How to restart WiFi interface without rebooting (it drops connection)?

  - by Dima

  I boot into ubuntu and it connects to the Wifi network fine. After about 10-15min the DNS stop resolving any website and a couple of minutes later network-managers tells me that I'm disconnected and tries to reconnect constantly to my router and fails to do it. Upon Ubuntu restart everything works fine for the first 10-15min again. When I boot into Mac OS X everything is fine with the same connection! How do I restart wifi interface? sudo ifdow wlan0 just tells me that wlan0 is not configured and wlan0 doesn't appear in /etc/network/interfaces either, which I find strange.... (unless network-manager is doing it behind my back).

• MAAS fails to Commission nodes

  - by user3644848

  I'm evaluating MaaS/Juju. I followed instructions in this link http://maas.ubuntu.com/docs1.5/install.html to setup MaaS. I'm running this in Oracle VirtualBox environment so Power options are not configured for the VMs. PXE booting VM works fine. The node shuts down itself and registers with MaaS in Declared state. Issues: a) When I Commission the VM (which is in the Declared state), first it gets IP-Config: no response after 60 secs - giving up errors. (See link below for a screenshot). b) Fails to mount the boot device and drops into initramfs prompt. I've copied logs here: https://www.dropbox.com/sh/5gy9nnonbnccufo/AAD9o4awSOtyaCCmRe5q7rBva Any help to get past this is greatly appreciated. Thanks!

• What does /dev/null mean in the shell?

  - by rishiag

  I've started learning bash scripting by using this guide: http://www.tldp.org/LDP/abs/abs-guide.pdf However I got stuck at the first script: cd /var/log cat /dev/null > messages cat /dev/null > wtmp echo "Log files cleaned up." What do lines 2 and 3 do in Ubuntu (I understand cat)? Is it only for other Linux distributions? After running this script as root, the output I get is Log files cleaned up. But /var/log still contains all the files.

• Retrieving snapshots of game statistics

  - by SatheeshJM

  What is a good architecture for storing game statistics, so that I can retrieve snapshots of it at various moments? Say I have a game, and the user's statistics initially are: { hours_played = 0, games_played = 0, no_of_times_killed = 0, } When the user purchases something for the first time from within the game, the stats are { hours_played = 10, games_played = 2, no_of_times_killed = 5, } And when he purchases something for the second time, the stats are { hours_played = 20, games_played = 4, no_of_times_killed = 10, } Let me name the events as "purchase1" and "purchase2" How do I model my statistics, so that at any point in the future, I will be able to retrieve the snapshot of the statistics at the time when "purchase1" was fired. Similarly for "purchase2" and any other event I will add. Hope that made sense..

  I am having problems getting grub to load Windows 8 properly after installing Ubuntu 12.10 and Windows 8 on a solid state drive. Here's what I did: Fresh install of Windows 8 using USB recovery drive (partitioned SSD for UEFI) -- Tested windows install and it worked fine Built bootable USB with Ubuntu 12.10 64bit and installed Ubuntu -- Used Ubuntu's installer to partition the Windows 8 partition and install there Reboot - try to load windows 8 from grub -- Ubuntu loads correctly; windows load reports various problems with permissions and not being able to find files - I'll update what the actual errors are Tried to fix the boot problem using boot-repair: -- here's the output: http://paste.ubuntu.com/1384522/ So, this is my first time trying to setup a dual boot system and I think that UEFI is the main culprit in getting this to work correctly.

• SOA Suite 11g (11.1.1.3): Creating a single server domain with SOA Suite and Oracle Service Bus func

  - by Chris Tomkins

  One of the major benefits of the latest version of the Oracle SOA products, SOA Suite 11gR1 PS2 (11.1.1.3) and Oracle Service Bus 11gR1 (11.1.1.3), is that both products depend on the same version of WebLogic Server 11g (10.3.3) and so can be installed in the same domain. If you are a developer building artifacts for both but with a laptop/desktop with limited resources then this is particularly useful, as you can install a single server domain (by default you get a domain with an admin server and multiple managed servers) which incorporates both sets of functionality. The viewlet below shows you how to go about creating such a single server domain, using the configuration wizard. Just click the Play button from the viewlet menu to start it. Note: As you have added all this functionality into a single server, it will take a few minutes to start up. As this is my first foray into the world of viewlets I’d be interested in your opinion as to whether you have found this useful and any tips/techniques for improving any future viewlets I may create.

  - by hal9k2

  As in the question above: What the best way to wire up Entity Framework database model (context) to viewModel in MVVM (WPF)? I am learning MVVM pattern in WPF, alot of examples shows how to implement model to viewModel, but models in that examples are just simple classes, I want to use MVVM together with entity framework model (base first approach). Whats the best way to wire model to viewModel. Thanks for answers. //ctor of ViewModel public ViewModel() { db = new PackageShipmentDBEntities(); // Entity Framework generated class ListaZBazy = new ObservableCollection<Pack>(db.Packs.Where(w => w.IsSent == false)); } This is my usual ctor of ViewModel, think there is a better way, I was reading about repository pattern, not sure if I can adapt this to WPF MVVM

• Looking for information on Scholastic BASIC programming books from the mid-1980s

  - by Jason Berkan

  My very first introduction to programming was in grade school, when I would purchase books full of BASIC code listings from the Scholastic school catalogue. Lately I have been searching teh Internetz for information on these books, but without any success. Does anyone know or remember anything about these books? All I can recall is that they were large paperbacks full of various BASIC code listings, some of which were game like. They all included instructions on how to modify the code listings for the different systems of the day, and I distinctly remember that they would always ask for a number in order to seed the RANDOMIZE command (since I figured out on my own that RANDOMIZE TIMER eliminated the need for the question and answer).

• Ubuntu gone out of order - Wont install any packages. What do I do?

  - by Aborted

  Lately, I've been getting some strange behaviour from Ubuntu. First and the most important is that it wont install updates. It gives a package installation error and it simply wont work. Earlier I tried to install TeamViewer via the Software Center, but got the same package error. I also feel like the connection speed is going slower than it should - don't know if this one is relevant to this case. What's wrong with my installation? How do I fix these package installation errors?
