• How can I get media keys working on my keyboard?

  - by Victor9098

  Just got a new keyboard, the Microsoft comfort curve 2000, and everything seems to work fine accept for the 'back' and 'forward' multimedia keys. I am running Ubuntu 11.10 and have tried going into system settings - keyboard - shortcuts, then I try and hold down the keys to set the action I want them to perform, but nothing changes. Any thoughts on where else to look? Thanks -- UPDATE -- I rebooted and the options to change the keyboard shortcuts seem to be working now. Now I can tweak the whole thing and I managed to assign the media keys correctly. Thanks to everybody for the suggetions

• HealthCare.Gov Fiasco

  - by jchang

  There will probably be consequences for delving into such a charged topic. But this has never stopped me before and I am too old to change my ways. So here goes. Many of us have of the problems with the online HealthCare.gov even though technical details are not yet available. First let me say that I am not singling out this particular project, as severe problems are common in government IT projects, and I suspect the incidence rate may be no different in private industry. Whereas other projects...(read more)

• How should I implement the repository pattern for complex object models?

  - by Eric Falsken

  Our data model has almost 200 classes that can be separated out into about a dozen functional areas. It would have been nice to use domains, but the separation isn't that clean and we can't change it. We're redesigning our DAL to use Entity Framework and most of the recommendations that I've seen suggest using a Repository pattern. However, none of the samples really deal with complex object models. Some implementations that I've found suggest the use of a repository-per-entity. This seems ridiculous and un-maintainable for large, complex models. Is it really necessary to create a UnitOfWork for each operation, and a Repository for each entity? I could end up with thousands of classes. I know this is unreasonable, but I've found very little guidance implementing Repository, Unit Of Work, and Entity Framework over complex models and realistic business applications.

• Collapsible menu and amount of links in a web page

  - by dstonek

  One of my pages contain three levels of a collapsible menu (JS + CSS from mycssmenu.com). There are a dozen first level items displayed to users, each one with various second level items, and finally a lot of third level items, each one containing a related link. This generates a lot of internal links (300+). Because of SEO should I change the way the collapsible menu is displayed to reduce link amount? What do you suggest? I would like to avoid users to have to open a new page just to only see what are third level items and eventually follow one of its links.

• Chameleon effect not working after update

  - by Roshnal

  I've been using Ubuntu 12.04 since it came out and so far didn't have any problems with it. But after I updated (via Update Manager) it yesterday, after every reboot, the launcher color defaults to a blue dash, workspace and trash icon and the rest is black. If I set the wallpaper again manually, then it changes color as its supposed to (chameleon). Any idea why this is? Its really annoying to change your wallpaper every time you logon just to get the "normal" launcher. EDIT The chameleon effect works perfectly for notifications. Only the Launcher and Dash are not changing the color. Thanks.

• Qt Quick : des interfaces déclaratives hors norme ? Pourquoi ne sont-elles pas encore répandues ?

  Il y a peu, Nokia lançait Qt Quick, un nouveau module de Qt permettant de décrire des interfaces graphiques, un paradigme alors présenté comme assez nouveau. Or, une simple recherche à l'aide de Google montre bien que ces technologies ne sont pas récentes du tout, on trouve par exemple des traces de K, un langage presque ésotérique tellement il est peu connu du grand nombre actuellement, dans les années 90. Qu'est-ce qui a changé depuis lors ? Aussi, on peut remarquer que d'autres technologies phares dans le développement applicatif telles que .NET ou Java en disposent depuis belle lurette. On peut notamment citer XAML (arrivé avec le .NET Framework 3.0) du côté .NET ou Swul pour Java. Qu'ont-ils donc de différent ? Peut-on les comparer ? Ils tentent tous d'atteindre un cer...

• How to run/test JavaScript? [closed]

  - by user702

  I'm reading David Flanagan's "JavaScript: The Definitive Guide, 6th ed". It only actually tells users how to run JS code on page 311, where users are told of the following solutions: "Client-side JavaScript code is embedded within HTML documents in four ways: Inline, between a pair of <script> and </script> tags From an external file specified by the src attribute in a <script> tag In an HTML event handler attribute, such as onclick or onmouseover In a URL that uses the special javascript: protocol." I was wondering what professional JS developers use to write and test their code: Do they use a good text editor with syntax high-lighting + autocompletion, hit F5 in the browser to reload the page every time they make a change, and use some add-on in the browser to investigate errors? Or are there full-fledged IDE's similar to MS VisualStudio for non-web languages?

• Ubuntu 12.10 dual boot windows 7 not working

  - by Joseph

  When i install ubuntu, and the computer restarts it doesn't show the boot managaer so it always boots in windows 7. I tried to change the default os, and ubuntu wasn't even listed in it. Then I read a how to on it, it showed how to size the partions and make them correctly, but it still didn't work. I tried easyBCD and still no success. I've tried installing it about 4-5 times and i still can't get it. What can i do to fix it?

• no windows 7 option after recent 12.10 install and boot repair

  - by user95240

  Earlier today i installed ubuntu 12.10 beta. Grub wasn't booting, but just going directly to my primary OS Windows 7. I assumed i had partitioned incorrectly, because partitioning isnt my strong suit. I used boot repair because it was well recomanded off a live usb. Afterwards, grub appeared, but i only had options for Ubuntu, Advanced Ubuntu Option, and my hidden windows 7 recovery partition. Please help me recover my access to windows partiton. See this link for Boot-Repair report: http://paste.ubuntu.com/1266467/ ps. ran Boot-Repair a second time - no change

• processing gamestate with a window of commands across time?

  - by rook2pawn

  I have clients sending client updates at a 100ms intervals. i pool the command inputs and create a client command frame. the commands come into the server in these windows and i tag them across time as they come in. when i do a server tick i intend to process this list of commands i.e. [ {command:'duck',timestamp:350,player:'a'}, {command:'shoot',timestamp:395,player:'b'}, {command:'move', timestamp:410,player:'c'} {command:'cover',timestamp:420,player:'a'} ] how would i efficiently update the gamestate based on this list? the two solutions i see are 1) simulate time via direct equation to figure out how far everyone would move or change as if the real gameupdate was ticking on the worldtick..but then unforseen events that would normally trigger during real update would not get triggered such as powerups or collissions 2) prepare to run the worldupdate multiple times and figure out which commands get sent to which worldupdate. this seems better but a little more costly is there a canonical way to do this?

• AdventureWorks2014 installation script

  - by John Paul Cook

  The AdventureWorks2014 sample database is downloadable from here . If you choose to run the script and are unfamiliar with sqlcmd, this post shows you what to do. Be sure to extract the zip file’s contents to a new folder because the instawdb.sql comes with 72 csv files that contain the actual data. If you specify a folder other than the default, you’ll have to change a path in the instawdb.sql script to point to your directory. Figure 1. instawdb.sql script file in SSMS.

• Next step after first few years at work [closed]

  - by juniordeveloper87

  Its been 2 years since graduating from uni and working in a IT solutions company as a programmer. My initial year was particularly exciting when we were trying to get a fresh product up to speed. The product has now gone live and are in the maintenance phase. My current day job involves merely bug fixing and also small designing/implementing change requests and also helping resolve issues faced from clients. Slowly I feel a little 'normal' in my role. I wonder how I can make myself stand out. (I work in a company of no more than 200 people) Or what should be the next step I take after 2 years doing programming? Thanks!

• Acer sound card

  - by Rob Brugh

  Hi I have an acer aspire on a recent upgrade somehow it loaded dummy output into upper memory so every time I boot up I have to manually load my sound card. using sudo /sbin/alsa reload then alsamixer and f6 to change to my proper sound card. How do I go about making that my default sound card loading on boot every time. sometimes the message comes up cannot find alsamixer, if that happens I have to run the following command sudo /sbin/alsa force-reload and then alsamixer. That works only on current session I would like to get that so it boots without coming up with dummy output. anyone out there know what the command is to make that load to boot section?

• Chessin's principles of RAS design

  - by user12608173

  In late 2001 I developed an internal talk on designing hardware for easier error injection, prevention, diagnosis, and correction. (This talk became the basis for my paper on injecting errors for fun and profit.) In that talk (but not in the paper), I articulated 10 principles of RAS design, which I list for you here: Protect everything Correct where you can Detect where you can't Where protection not feasible (e.g., ALUs), duplicate and compare Report everything; never throw away RAS information Allow non-destructive inspection (logging/scrubbing) Allow non-destructive alteration (injection) (that is, only change the bits you want changed, and leave everything else as is) Allow observation of all the bits as they are (logging) Allow alteration of any particular bit or combination of bits (injection) Document everything Of course, it isn't always feasible to follow these rules completely all the time, but I put them out there as a starting point.

• nicstat update - version 1.92

  - by user12608033

  Another minor nicstat release is now available. Changes for Version 1.92, October 2012 Common Added "-M" option to change throughput statistics to Mbps (Megabits per second). Suggestion from Darren Todd. Fixed bugs with printing extended parseable format (-xp) Fixed man page's description of extended parseable output. Solaris Fixed memory leak associated with g_getif_list Add 2nd argument to dladm_open() for Solaris 11.1 Modify nicstat.sh to handle Solaris 11.1 Linux Modify nicstat.sh to see "x86_64" cputype as "i386". All Linux binaries are built as 32-bit, so we do not need to differentiate these two cpu types. Availability nicstat source and binaries are available from sourceforge.

• Ubuntu user expectations from 12.04 and future releases

  - by Rick Green - Turbo

  How much further ahead is 12.10 vs 12.04 in respect to kernel updates and applications? Example: Gimp's newest release is 2.8 which runs equally as well in both 12.04 and 12.10 and probably will in 13.04. What restricts 12.04 from having "the same" look, feel, applications and kernel as 12.10 or the upcoming 13.04? I know that it's more than a name change.....it's whats under the hood that counts. Incrementally upgrading, I feel is safer than radical changes from release to release. Trying to keep a stable desktop and current user experience, how far can I take updating applications before I absolutely have to make a distro upgrade from 12.04LTS

• LibreOffice can't open a spreadsheet

  - by dn.usenet

  I have been editing my-file.ods almost daily using LibreOffice. Today it hanged at one point. I had to reboot the laptop. Now the file cannot be edited. When it is opened for editing, a warning is issues: Document file is locked for editing by unknown user. If I open the file for editing despite the stated hiccup and edit it and then try to save it, I am prompted to save it under another name. But I don't want to change the name.

• Upgrading Ubuntu to 12.04 stuck

  - by Chris Britt

  While upgrading from 11.10 to 12.04, I'm stalled at the step: Installing new version of config file /etc/init/udevtrigger.conf The Terminal in the Distribution Upgrade window is expanded, there is no prompt for user input. I've hit enter a few times but it doesn't change anything but add a blank line after the last print statement. It's been sitting for ~6 hours at this stage. No other windows or dialog boxes are open. The upgrade has progressed through "Preparing to Upgrade", "Setting new software channels", and "Getting new packages". Under the progress bar (which estimates 1 day 2 hours remaining, and has for some time), it says Preparing to configure libpcap0.8. I'd take a screen-shot, but it won't let me save the file anywhere. The progress bar is about 1/3 complete.

• How do I fix hibernate?

  - by Vivek

  Suspend and Hibernate was not working in my Ubuntu 11.04 and I followed these instructions to fix the issue by installing uswsusp. The commands s2ram and s2disk were working fine for me and hence I replaced the contents of hal-system-power-suspend-linux and hal-system-power-hibernate-linux as directed in the above link. Now after my upgrade to Ubuntu 11.10, I am unable to hibernate my system. How to rectify this issue? Is there any config file which I need to change for hibernate to function properly?

• New Window Via JavaScript Clears Parent

  - by Bunch

  This is not a new item at all but I came across it recently. For an app I had been using some JavaScript like: javascript:window.open(someurl.aspx here) to open a new window via a button. That bit of code had been working great in several other apps. Then in one app that same code decided to open the new window correctly while clearing the parent of everything but [object]. The fix ended up being simple, change the javascript to: javascript:void(window.open(someurl.aspx here); Then it worked like I thought it should. Tags: ASP.Net, JavaScript

• .xprofile isn't enough

  I've been trying to find a solution on how to change the screen resolution on the login screen and other users. .xprofile will only affect my account.
