• HD Video on Pandaboard ES

  - by Lord Loh.

  I am running Ubuntu 11.10 on my Pandaboard ES. I attempted to playback a 720p / 1080p video. In both cases, the videos were highly jittery and the audio seemed to be plagued with something that seemed to be white noise (sounds like white noise, but it definitely is not white noise). I was using VLC media player for playback and was running XFCE4 as…

• What techniques are used in solving code golf problems?

  - by Lord Torgamus

  "Regular" golf vs. code golf: Both are competitions. Both have a well-defined set of rules, which I'll leave out for simplicity. Both have well-defined goals; in short, "use fewer hits/characters than your competitors." To win matches, athletic golfers rely on equipment Some situations call for a sand wedge; others, a 9-iron. techniques …

• How can I find a good open source project to join?

  - by Lord Torgamus

  I just started working a year ago, and I want to join an open source project for the same reasons as anyone else: help create something useful and develop my skills further.

• Processing a stream. Must layers be violated?

  - by Lord Tydus

  Theoretical situation: One trillion foobars are stored in a text file (no fancy databases). Each foobar must have some business logic executed on it. A set of 1 trillion will not fit in memory so the data layer cannot return a big set to the business layer. Instead they are to be streamed in 1 foobar at a time, and have business logic…

  - by Lord Chumley

  I have some external fonts called Eaglefeather (Frank Lloyd Wright fonts) and I want to install them on to my Linux machine running Linux Mint 7 (Ubuntu based). I can't seem to get them to install which looks to me like just copying them to the /usr/local/share/fonts directory.

• Why does my Internet slow to a crawl unless I reboot my router every few days?

  - by Lord Torgamus

  A few weeks ago, I noticed that my Internet connection had slowed down to a crawl. I waited a few days hoping it would go away on its own, but it didn't get better. So I asked this question about how to make it faster. The problem went away after I updated to the latest firmware, so I didn't follow up too carefully. But every few…

• Create an alias in Windows XP

  - by Lord Torgamus

  Back in school, I used to have a .login file along the lines of alias ll = ls -l alias dir = ls -Fhl alias web = cd ~/public/public_www/development ... I'd like to do that sort of thing with my XP box here at work, but most of the resources I've found online seem fairly complicated and heavy-duty. Is there…

• Firefox window disappears

  - by Lord Torgamus

  Now this is odd. At some point in the last half hour, my Firefox window disappeared. I didn't notice, as I was working in another program at the time. No Firefox icon shows up with Alt-Tab, and no Firefox listing shows up under the Applications tab in the task manager. There is a Firefox entry under the Processes…

• How can laptop keyboard keys be removed and replaced?

  - by Lord Torgamus

  I'm trying to fix a laptop keyboard that has issues with keys on its left side. Just by feel, it's clear that something sticky got under there. There could be something crunchy too, but that might just be the sound of the key's spring releasing itself from the sticky. I don't know the cause because it's not my…

• How can I restrict a group to reading only two particular folders with Windows Server?

  - by Lord Torgamus

  I have a group of users on Windows Server 2003 who need to be able to read the contents of two directories but not be able to access anything else on the server (including read-only access). One of the directories is K:\projectFour\config — and the other is similarly formatted — so it would be okay for group…

  A guy I work with just came by to ask me about a damaged thumb drive/USB flash drive. Apparently his son dropped it on a hard surface and it won't power up anymore. They've tried plugging it into multiple machines without success, even though each port they tried was able to power other USB…

  Is it possible to list all folders/files that a given group has explicit permissions on, for a machine running Windows Server 2003? If so, how? It would be nice to see inherited permissions as well, but I could do with just explicit permissions. A little background: I'm trying to…

  This question is inspired by another SU question I came across earlier today: What to do with old hard drives? It made me think about two long-dead laptops I have with perfectly good screens still inside. One is a Dell Inspiron 5100 and the other is an Averatec E1200, but responses…
