New system audio problem
by Stephen 11 Apr '15

11 Apr '15

Background: I have run Ubuntu 12.04 and earlier versions for a number of years on an MSI motherboard and an AMD 3200 cpu. It finally died. I build a new system on a ASUS H97M-E motherboard with an Intel i5 and 16 gigs ram. I just connected the hard drives from the old system, and was quite happy when the system booted and all seemed good. Problem: Audio is bad. Static and drops. This applies to *.flac files and online Youtube stuff. But when I play *.mp4 files, the video and audio are great. My Ubuntu system is a DLNA server and and that plays fine on the client. So I am thinking the audio driver is not a good fit for the new chip set. Am I on the right track? Can I get Ubuntu to update to the proper driver? Thanks -- Stephen

Git Large File Storage extension
by Giles Orr 09 Apr '15

09 Apr '15

Github has developed a "Large File Storage" extension to git. Written in Go, open sourced. https://github.com/github/git-lfs This is their blog announcement: https://github.com/blog/1986-announcing-git-large-file-storage-lfs I haven't dealt with the problems of large files in git, but I've heard it's ugly, so this is interesting. I'm curious if more experienced git users actually think this is a good idea. -- Giles http://www.gilesorr.com/ gilesorr(a)gmail.com

git questions
by Giles Orr 07 Apr '15

07 Apr '15

I've started using git fairly heavily (although not necessarily very well). I have several repos: a couple are code, also my ~/.vim/ folder and I'm thinking about adding ~/bin/ . If I remember to push from a particular machine before leaving it, I'll never have to deal with merging as I'm the only user. While most likely my discomfort with merging will be overcome by practice as I understand git does it well (I use SVN at work: merging is shudder-inducing), I'm guessing keeping everything up to date is still preferable. These questions are mostly about incorporating information about the repo into the Bash prompt: I was impressed recently by the way zsh appears to handle it, with a sequence of tiny icons in the lower right corner of the terminal indicating relative status. I didn't talk to the zsh user long, so I don't know if that's built-in, a plugin, or something he did himself. I'm starting from some code I got from nitrous.io, lovely in its conciseness: parse_git_branch () { git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/* $.*$/\1$(parse_git_dirty)/" } parse_git_dirty () { git diff --no-ext-diff --quiet --exit-code &>/dev/null || echo "!" } Put \$(parse_git_branch) into your prompt and it tells you what branch you're on, and if there are any unstaged changes (and goes away if you're not in a repo). I'd prefer it did uncommitted rather than unstaged, haven't tried to fix that yet. But I want to update it as it doesn't deal with origin at all. So, the questions: What is the easiest and most concise way to determine if your local is behind origin master? I've found that "git remote show origin" will show this information, but I'm not sure if it's the "best" way to find out, and I'm also concerned that running that every time your prompt comes up would slow things down as it makes a remote call(?) to get an answer - when you might not even have a network connection, or worse, a very slow connection. "git status" usually says "Your branch is up-to-date with 'origin/master'" (or "ahead"), but occasionally - even though origin is configured properly - this line doesn't appear. Is there a way to convince it to always show this line? Unfortunately, "git status" doesn't seem to ever notice if you're "behind" origin, thus the need for "git remote show origin". Any fix for that? The thought was to have output for the prompt that looked like this: (everything synced): "master-" (uncommitted local changes): "master!-" (behind origin): "master^" (ahead of origin): "masterv" (ahead and behind, with local changes): "master!^v" You get the general idea. I'm aware git is capable of immense complexity (branches, detached head, multiple remotes, different remotes for push and pull, etc.) that aren't addressed here. If I tried to tackle all of that at once (especially given I don't understand most of it) my head would explode and nothing would get done. So I'm sticking with my simple use case until I have to deal with the more complex stuff. Any thoughts welcome. -- Giles http://www.gilesorr.com/ gilesorr(a)gmail.com

Where can I buy short ethernet and USB-to-microUSB cables?
by Walter Dnes 06 Apr '15

06 Apr '15

Two items I need to buy... 1) I have more devices than ports on my 4-port ST546 ADSL modem/router. I have a multi-port bridge sitting right next to it. A 6-foot ethernet cable connecting the 2 is a waste, and contributes to "crow's-nest". A 12 or 18 inch ethernet cable would do just fine. 2) Ditto for a short USB-to-microUSB adapter. A 6-footer is OK for my desktop. But when I'm travelling, and offloading smartphone photos to my laptop, a 6-foot cable is clumsy. -- Walter Dnes <waltdnes(a)waltdnes.org>

Help; system date goes to GMT hour when I hibernate

I have a bunch of spreadsheets, browser tabs, etc, open all the time, scattered over various work areas. Rather than re-open them every day, I simply hibernate, using suspend-to-disk. This way, things are where I left them. The past couple of months, when the machine comes up from hibernation, the clock is a few hours ahead. Now it's 4 hours ahead. It was 5 hours ahead before the switch to daylight savings time. This looks suspiciously like GMT. After reading your email, I dug deeper. Apparently, it's just the "kernel system time" that gets bumped forward when it comes up from hibernation. The BIOS clock is OK. As a heavy-handed hack, I've inserted the line... OnResume 01 hwclock --hctosys ...into my /etc/hibernate/hibernate.conf. This copies over the BIOS time to the kernel system date. It works, but I'd really like to know why it's necessary in the first place. -- Walter Dnes <waltdnes(a)waltdnes.org>

[OT]: Two matched ATX towers looking for a home
by Scott Sullivan 03 Apr '15

03 Apr '15

I have two ATX towers that are looking for a good home. Contact me off list. Free to whomever that will do _pick up_ in North York. Their main feature is a lot of 3.5" and 5.25" bays for larger numbers of hard drives. http://revident.net/images/20150403-atx-towers-for-give-away/ Their in good condition, steel construction. -- Scott Sullivan
