• downgrade ppa packages to versions available at a previous point in time

  - by Will

  The backstory is that the normal Intel GPU drivers don't do the various OpenGL extensions that my hobby coding and some games want. So I have to install xorg-edgers and then its happy. However, last Wednesday or so there was an update to xorg-edgers - lots of packages - and it broke badly; the drivers lock up and take the whole computer with them; hard reset required. So how can you downgrade - select package versions in a PPA that represent a point in the past, ignoring versions newer than that?

• 14.04 Chinese Ibus Input - No Options

  - by RhZ

  getting my new 14.04 rig going ;-) Pretty happy with it, everything seems to be working great. For Chinese input, however, having a problem. I went through the typical steps, open language in settings, let it install some stuff, then add Chinese and choose Ibus. Then, after logging in and out, I see the language icon in my system tray. However, when I go to add the Chinese into Ibus, it only lets me choose "Chinese", which isn't an input method. It should give me a bunch of choices like pinyin, bopomo or whatever, I only use pinyin so don't know those names. I saw someone online had a little command which helped people with similar problems, but it did not work for me, even after a re-start. So, anyone got a solution? Edit: Here is what it looks like, just "Chinese" in the list, when there should be a bunch of input options like pinyin, potomofo, and so on.

• Friday Spotlight: Oracle Secure Global Desktop and amitego VISULOX

  - by Chris Kawalek

  Happy Friday! Our spotlight this week is a screencast about a fantastic solution that takes the security model of Oracle Secure Global Desktop and adds even more features. If you work in environments where you need to have a video record of users' interactions with applications, or need to ensure that two users can remotely work on the same session (a worker entering data in a form from one workstation and a manager typing an authorization code from another, for example), amitego VISULOX can do this and a lot more. It's built on top of Oracle Secure Global Desktop, so you get all of the great features there, plus additional unique security related features provided by VISULOX. Click the thumbnail below to watch the screencast. We'll see you next week! -Chris

• What is the next promotion for a scrum master

  - by gnebar

  I'm currently a scrum master. I have been offered a promotion to a role that will allow me to have a wider impact. (more involved in company wide architectural decisions, possible secondment to kick start major projects, etc). The role and title of the job has yet to be decided but my company are open to guidance from me. I'm happy I can mould the role to suit me and the company but I'm unsure about the job title that fits this role. Technical Evangelist has been suggested but i'm not sure that is the correct title. I'm keen to proceed down the technical route. What would you suggest? What other roles do people take after scrum master/technical lead? EDIT: (I am aware that my current role is a mix of a technical lead and scrum master role, but that's how we do it in my company :) )

• How to convert an XFS file system to HFS+

  - by user219350

  I have repeatedly convinced of the reliability of the XFS file system , and I was more than satisfied . I was happy with everything in Ubuntu 14.04 ( great software) , but there is a little "but ! " Basically, I work on OSX-Mavericks 10.9.3, which sees very Windows 8.1 and works wonders with NTFS, but does not see Ubuntu! Briefly describe the equipment: ASRock B75 Pro3-M i5 3330 GeForce GTX 650 Ti SATA 500GB running OS X Mavericks + Clover - a boot disk Toshiba 2TB running Windows 8.1 (x64) and Ubuntu 14.04 (amd64) If you boot from the Toshiba (where there is Ubuntu and boot Windows + GRUB) after restart boot from Clover, it is impossible. Tried a lot of options - as Clover installation and boot priority, and various settings for GRUB, but have not found an acceptable option and have no desire to reinstall again Clover (Mavericks reboots 20 seconds - excellent!) So please help on the file system - how to convert from XFS to HFS+ journaled. Mavericks to saw it all synced on Mac. Thank you for the sensible answer and help! Originally in Russian.

• How do you stop yourself from programming?

  - by dan

  Lately I've started earning enough off my software to not have to do consulting to support myself. So I work full time designing and writing my own software products. The problem is that there are no boundaries between my work and my life any more. When I mostly did consulting, I was weary enough of work at the end of the workday to go home and do other things. But now, I sit down to program in the morning, and before I know it it's 11pm and I'm still writing software and not bored or tired at all. I have to force myself to go to sleep. I feel happy and fulfilled, but objectively, I know I need more balance and variety in my life. Any tips or suggestions on how to pull yourself away from the console?

• 13.10 Cursor Disappearing?

  - by ConnorRoberts

  Upgraded from 13.04 to 13.10 on my Ideapad Yoga yesterday, hoping it might have fixes for a couple of issues I've been having. While it seems to have made the touchscreen more usable, it has made the problem with my trackpad even worse :( In 13.04 and below, the cursor occasionally (maybe once or twice a day) would completely stop working and to get it working again I would run sudo modprobe -r psmouse sudo modprobe psmouse and it would be happy again, now every hour or so, my cursor just goes invisible, you can tell its still there as you can hover over things and they will respond. Again running sudo modprobe -r psmouse sudo modprobe psmouse works but it's getting a little annoying now its so frequent! Does anyone have any suggestions on things to try? :( Thanks in advance!

• I want to use the fleximage gem and s3 for storage, but don't want dev/qa/test env's to use s3

  - by Kevin Bedell

  I have a rails app that I'm going to host on engineyard and want to store image files on s3. But I don't know if I want all developer machines to beusing s3 for storage of all our test and dev images. Maybe it's not an issue -- but it seems like a waste to have everyone storing all our images in s3. I've heard of some ppl who store images on s3 'hacking' dev environments to store images locally on the file system -- and then using s3 in prod only. What are other people doing?

• Design leaderboard ratings for quiz games

  - by PeterK

  Back in March 2011 i started the following post: How to design a leaderboard? Now my quiz game have been out for approximately a year and sold pretty decently. I am working on to update the game design and is again looking into the leaderboard design to make it better as i am not happy with it. Currently i rate players on number of correct answers, which is not good as it does not consider things like number of games, difficulty levels etc. I also have "extended" stats behind the UITableView (Leaderboard). A player can play based on three levels of difficulty: hard, medium or easy Difficulty levels can be mixed between players in a game Each game can be one to six players, so there can be single games or duels Between 2 and 30 questions per game As i am considering integrating Game Center Leaderboard i need to design a better rating system so i would like to ask for some ideas how to do the rating based on the above. I am thinking about how much a point would be worth and what it includes.

• Oracle Linux Friday Spotlight - November 8, 2013

  - by Chris Kawalek

  Happy Friday, everyone! This week, I want to highlight a really wonderful resource, the Oracle Linux Wiki on wikis.oracle.com. You can find a lot of in-depth technical information there and it’s probably worthy of a bookmark to check in on occasionally. One of my favorite types of content on the wiki is the do it yourself hands on labs. We do these at in person events like Oracle OpenWorld and also online for our Virutal SysAdmin Days, and those are great because you can get real-time assistance if you have any questions. But, if you’re eager to learn more about Oracle Linux and don’t want to wait for one of those events, you can step through these labs in your own time. All of the information you need is on the wiki. We’ll see you next week! -Chris

• How do I get Cabal to bypass my Windows proxy settings?

  - by Brent.Longborough

  When retrieving packages with Cabal, I frequently get errors with this message: user error (Codec.Compression.Zlib: premature end of compressed stream) It looks like Cabal is using my Windows Networking proxy settings (for Privoxy). From digging around Google, Cabal or its libraries appear to have (had) a problem in this area. Possible solutions I can see are: Turn off proxying while using Cabal (not very keen on this one); or Get a patch and start hacking. I'm hesitant to go down this path, as I'm a complete Haskell noob and I'm not yet comfortable with Darcs; or Give it the magic "can I haz no proxy" parameter. Hence the question.

• T420 Triple Head with Optimus

  - by Rolo

  I see that this is possible on a T520 apparently (Triple-head on a Lenovo T520), but I can't see anyone claiming it's possible on a T420. I'm running 12.04 and have Bumbleebee installed and working fine but I can't get the display port monitor to display anything. The power light flicks on, but things only render on my VGA output monitor, and Ubuntu's display settings don't detect the third monitor. I'm not concerned with power management, ie, am happy to leave set on discrete graphics in the BIOS if that helps. Is this possible? Thanks.

• Why is a menu item disabled when using SWTBot?

  - by reprogrammer

  I've written up a GUI test using SWTBot to test the Extract Method refactoring. I use editor.selectRange() to select a statement to extract into a method. But, when I run the unit test, the Extract Method refactoring menu item is disabled. Thus, SWTBot fails to invoke the refactoring. When we change org.eclipse.jdt.ui.actions.ExtractMethodAction so that the "Extract Method..." menu item is always enabled, our SWTBot passes. But, SWTBot should let us select the menu item without hacking the org.eclipse.jdt.ui plugin. The whole project containing the above unit test is available at github. I've also reported the problem on the Eclipse forum for SWTBot. But, we haven't received a solution from the forum.

• How do I disable the "enable/disable wireless" shortcut key on my laptop?

  - by Matthew

  On my Dell Studio XPS 16, I sometimes accidentally hit this key. Wireless becomes disabled, and hitting it again does not re-enable wireless. I have to hit it an odd number of times, then restart my computer to re-enable wireless. I can't imagine a situation in which I would want to disable wireless from my keyboard. Is it possible just disable the key all-together, so I can avoid this problem? On a related note, what package do I file the bug against? I'm happy just disabling the key, but that's really just a workaround.

• Evolution and thunderbird sharing same mail data?

  - by balki

  Hi, I have been using Evolution for a quite long and it has downloaded around 1.6GBs of mails from gmail. I want to try thunderbird but I dont want to re download everything again. Is that possible to have both clients sharing same data? I'll make sure I don't use both at the same time if that matters. I'll move to thunderbird fully if I'm happy with it. Problems I face with evolution is that I have to have the GUI running always if I want to get instant alerts and send mail immediately. Also it loads the messages slow and even after I move to the next mail, it slowly downloads all the linked images before moving on.

• How do you know when to change jobs? [closed]

  - by dustyprogrammer

  Possible Duplicate: When do you know it's time to move on from your current job? I have been working for a couple years now. I just want to know what people think about leaving one company for another, or to start looking around for other positions. I tend to use people's resumes as a guideline for when to change from one company to another. I am approaching, the time in my life where most of those people I look too, move away from their first position to pursue others. I know that isn't something good to base my decisions on what other do. I was wondering when is it time to move companies. I am currently happy at my position, and I am learning tons. Its just something I have been seeing a lot, I would like to get a feel for what people think. Thanks.

• LL(8) and left-recursion

  - by Peregring-lk

  I want to understand the relation between LL/LR grammars and the left-recursion problem (for any question I know parcially the answer, but I ask them as I don't know nothing, because I am a little confused now, and prefer complete answers) I'm happy with sintetized or short and direct answers (or just links solving it unambiguously): What type of language isn't LL(8) languages? LL(K) and LL(8) have problems with left-recursion? Or only LL(k) parsers? LALR(1) parser have troubles with left or right recursion? What type of troubles? Only in terms of the LL/LALR comparision. What is better, Bison (LALR(1)) or Boost.Spirit (LL(8))? (Let's suppose other features of them are irrelevant in this question) Why GCC use a (hand-made) LL(8) parser? Only for the "handling-error" problem?
