Tet Re:I have everything in FLAC too (4 comments)

Yep. I rip to Vorbis as well, so that I can easily scp music to my work computer without having to transfer the full FLAC file over my relatively slow ADSL line. The extra 10% storage it uses is essentially insignificant.

Tet Re:Most everyone is lying. (280 comments)

No, my car doesn't have an OS. My TV is probably 50/50. The only OS I interact with on a daily basis is Linux. Unless you count firewalls which are IOS at work and OpenBSD at home. But I'm not sure I'd say I'm really interacting with them.

I'll ask my electrician for a full size rack on wheels, but if he can't get one, the wall mount it is

Unless you need the full 42u, I'd definitely go for something smaller. A half-ish rack on wheels should be more than adequate, will be less imposing, and they're relatively cheap, too. We have a couple in the office at work because the few machines that aren't in one of the data centres don't need a full height permanent rack. I can't believe there isn't a suitable supplier in Luxembourg, given the number of financial institutions there. But if not, there should be plenty in Germany, right?

Nvidia's Fermi Architecture Debuts; Nouveau Driver Already Working

Tet Re: Nouveau (70 comments)

Also, good luck getting multiple monitors to work

I've had far more success with multiple monitors using nouveau than with the proprietary Nvidia drivers. I'm currently running with 4 monitors using nouveau, and have been for many years. Further, in the last few years I haven't encountered anyone else that's had problems with multiheaded support in nouveau either, and we have an office full of people doing so here.

Canonical's Ticking Time Clock

Tet Re:Canonical (11 comments)

I am stuck with a linux desktop that can't talk to my camcorder, scanner (though the linux-compatible printer now *finally* works), etc.

To be fair, those things are rarely due to resources being spread too thinly or duplicated efforts elsewhere and are far more commonly caused by patents, obstructive vendors and unethical business practices. Apple gets around this by paying the vendors, which simply isn't an option for most Linux distributions.

Red Hat seem to have a pretty good business model when it comes to open source, and are now a billion dollar company. That shows that you can do it. I don't think Canonical can follow their example, though.

Ask Slashdot: Good, Forgotten Fantasy & Science Fiction Novels?

Tet Re:Stephen R.Donaldson- Chronicles of Thomas Coven (1244 comments)

But they are the only modern fantasy novels that are on the same high level as Tolkien

I couldn't disagree more. Donaldson has a terrible writing style that has a few brief moments of greatness and a lot of tawdry mediocrity. He doesn't come close of Tolkien on any level, and I found "The chronicles of Thomas Covenant the unbeliever" to be very dull for the most part. I wouldn't recommend them to anyone.

Is the GPL running out of steam?

Tet GPL (3 comments)

You're wrong. Code isn't always submitted back to the project. I can point to several examples of this. Hell, in many cases, code isn't even forthcoming where it's covered by the GPL and there is a legal obligation to do so. Your irrational hatred of the GPL seems to be blinding you to the facts here.

Heh. I read this a few days ago, but I hadn't noticed that you'd written it. I agree with nearly all of it. It's not a viable business, and there's only so long Shuttleworth can keep bankrolling it. Personally, I think it's a weak excuse for a distribution, too.

Tet Re:SELinux (35 comments)

If you believe SELinux to add minuscule extra security, you might want to read up on it a bit more. For me, it's perhaps the single most important security feature you can add to a modern OS, and it's hard to understate just how much extra security it buys you (although obviously that is dependent on the policies you put in place -- it is after all just a framework to allow you to specify security policies). And I'd argue that a desktop is far more in need of the protection it provides than servers (which realistically are pretty secure in the first place). A desktop has a larger attack surface than a server, and is exposed to far more malicious parts of the net than a server is.

Tet Re:OOM? (35 comments)

I'm not "arguing for the sake of arguing" - I would really like for people to give this whole swap/no-swap thing a try

Oh, I have done. And I mostly agree with you. RAM is cheap, and it makes sense to take advantage of that. But no matter how much RAM you have, you have to give some thought to what you want to happen when you run out. Because you will. If letting the OOM killer nuke the process it thinks is most problematic is acceptable, then fine. But there are plenty of situations where that's not OK and sometimes, having some swap is the right answer. The whole idea of swap needing to be double the amount of RAM is nonsense and anyone doing such a thing in today's world need their head examining. But I tend to have a few hundred MB of swap on my servers and for me, that's a win over having no swap at all.

Tet SELinux (35 comments)

the evil part SElinux. I removed it

Possibly the worst decision you'll ever make when it comes to Unix sysadmin. SELinux is an absolute essential on any box I own. I can't see why anyone would trade security for a minor[1] performance gain.

[1] From my experience, 7% is a massive overstatement, and I'd say it's closer to 1% or 2%. But even if you're right and it's much more than that. Say 25% (which it isn't). I'd still say it's worth it...

Mozilla

Tet Re:Moo (9 comments)

Plugins are probably the only thing keeping it alive.

Perhaps, although in this instance, they're the source of my problems. My main machine died, so I switched to using the spare (which brought with it a 32-bit to 64-bit transition). My home directory is NFS mounted, and so shared between both systems. Consequently, none of my plugins work, because no one at Mozilla thought about this:

LoadPlugin: failed to initialize shared library /local/opt/x86/linux/flash_plugin-11.1.102.55/libflashplayer.so [/local/opt/x86/linux/flash_plugin-11.1.102.55/libflashplayer.so: wrong ELF class: ELFCLASS32]

It would have been trivial to put plugins into an architecture specific directory. This has been common practice in the sysadmin world for donkey's years. I've been doing it since the mid-90s, for example, and I learned about it from people that had been doing it for years before that. But no, Mozilla is written by people from a Windows background with no concept of such things.

KVM recommendations

Tet Tet writes  |  about 8 months ago

I appear to be in the market for a new KVM as my current one has all but stopped working. Any recommendations? Minimum 4 outputs. *Must* do VGA. My current one has mini-DIN for keyboard and mouse, which has sort of worked some of the time with USB-PS2 converters. I could probably go for a full USB only one, but I'd need to get new cables.

Tet Tet writes  |  more than 2 years ago

My decision to rip all of my audio losslessly to FLAC has been vindicated. I rip to Vorbis as well, but I always thought it was worth having the lossless originals around too. That way, if a new codec arrived on the scene at a later date, I could rerip to that without any further loss of quality. That codec is now here. Hello, Opus!

On the merits of redundancy

Tet Tet writes  |  more than 2 years ago

Some people think I'm paranoid. I wouldn't say so. It's just that I pay more attention to the potential worst case outcome that some. So when it comes to storage, I have a mirrored RAID array in my home server. The contents are backed up to a separate disk in the same machine. I also have an offsite backup in a datacentre.

My offsite backup machine died, and is now sat at home waiting for me to rebuild it. So it was somewhat alarming when my backup drive also died. Uncomfortable about running with less redundancy than normal, I immediately went out and bought a replacement drive. When checking the drives in the machine to see which one I needed to pull out, I noticed that one of the mirrored drives had also failed and the array was running in degraded state. Eeeek! Of my four levels of redundancy, three had failed. If I'd had fewer, I'd be screwed right now!

I'm not sure why I wasn't notified about the RAID failure. Normally I automatically get an email when the array enters a degraded state. That's something I need to look into. For now, the array is rebuilding. I'll fit the new backup drive when I get home this evening.

Hard drives

Tet Tet writes  |  more than 2 years ago

Time for more storage. Where's the current sweet spot? It looks like drives are considerably more expensive than I was expecting. I'm guessing that's still a hangover from the flooding in the Far East. I'm considering a Samsung HD204UI or a Seagate ST2000DL003. Both are 2TB, which is about right for what I need. Both are slow (5400 and 5900 rpm respectively). That's OK. I/O performance is not the bottleneck here. That said, I'd rather have a bit quicker, but going up to 7200 rpm adds significant extra expenditure.

I'm way out of touch with PC hardware standards. The Seagate is nominally SATA III (a misnomer, IIRC). Will that be backwardly compatible with my SATA I/II controllers, or will I need to upgrade those as well? Any other suggestions on models I should be looking at, or things I should be considering?

The perils of progress

Tet Tet writes  |  more than 3 years ago

Ever increasing storage capacity is making me lazy. In years gone by, when resources were more limited, a full filesystem would be cause for investigation, to find out why it had become full, and what could be done about it. These days, the easy option is to just extend the volume a bit more and grow the filesystem. I'm running a bit low on free PV space, so last week I didn't grow my home filesystem by as much as I normally would when it filled up. But even so, I was a little surprised to find out that within a couple of days it was already full again. That's not normal. It turned out that a single log file was continually growing and had taken up nearly a third of the total space on that filesystem. But because the default assumption is that I have more disk space than I'll be able to use, I hadn't been keeping an eye on what was taking up the space. D'oh! So a single rm has taken me back to having loads of free space.

Farewell Libya

Tet Tet writes  |  more than 3 years ago

So Libya has cut itself off from the net. This isn't an entirely unexpected move. But it has the side effect of screwing over anyone with a .ly domain. The main loser there is probably bit.ly. It still seems to be up at the moment, but I'm guessing that DNS caches will expire soon enough and then they'll be in trouble.

But somehow I just can't find it in me to feel any sympathy for them. At the time they launched, I pointed out that they were putting themselves at the mercy of the Libyan government. But it seems they preferred the two digit .ly ccTLD to the three digit .com domain they could have used instead. There are times when convenience trumps reliability. But this wasn't one of them. I wasn't expecting it to go wrong as quickly as it did, but I was aware of the possibility. It seems they either weren't aware of it, or chose to ignore the risk. That wasn't the wisest move in the world, even without the benefit of hindsight.

Maybe it'll act as a warning to those who have jumped on the .co bandwagon recently. But I doubt it. So I won't be surprised if the Colombian government screws them over at some point, in the same way the Libyan government has just done. And I won't have any sympathy for them, either.

...and then there was silence

Tet Tet writes  |  more than 4 years ago Once you've been around computers for a while, you get to recognise certain sounds. Such as the pop followed by the spinning down of fans, and the ominous silence that emanates from the box that's supposed to be your fileserver. Arse. I was off work yesterday due to a nasty cold, and the last thing I wanted to be doing was rebuilding the server. Fortunately, it turned out to be just the power supply. I'd been worried that it was going to have taken out the motherboard too. It did take a hard drive with it on the way out, but fortunately that wasn't fatal. The RAID rebuild ran OK overnight, and now we're back to normal.

Zooming/panning images for video

Tet Tet writes  |  more than 4 years ago Does anyone know of a good solution for zooming/panning static images for turning into a video? The so called Ken Burns effect? It must work on Linux, and should ideally be open source. The pan in openshot doesn't seem to work, and the zoom is too jerky to be useful. I can write my own fairly easily if I have to, but I'd rather not reinvent the wheel if I can avoid it.

The WebM project

Tet Tet writes  |  more than 4 years ago http://www.webmproject.org

It's what we were all hoping for, and I'm pleased that it's come to pass. It's not perfect, and I don't agree with all of their decisions. However, even an imperfect alternative to the current H.264 situation is a massive improvement. I'm pleased they've gone for a full stack solution of not only VP8 but also Matroska(-ish) and Vorbis, too. If nothing else, it's likely to mean that a) Vorbis will be shipped by default on most platforms[1], and b) hardware support for both VP8 and Vorbis should be widespread in the very near future. Further, there's a commitment to transcode all of the existing videos on YouTube. That's a massive endorsement. Of course, the risk with that is the reduced quality that will come from three or more lossy transforms, but given that they've announced it, they're clearly not too concerned about that. The future's looking very bright indeed.

[1] Or will it? I've yet to see any official response from Microsoft or Apple on this. But it's going to be hard for them to ship something that won't play YouTube videos by default. Of course, in the short and probably medium term, YouTube will continue to offer videos in other formats as well. But we'll see how it plays out in the long term.

I want a bigger computer

Tet Tet writes  |  more than 4 years ago I went to an interesting talk by Eng Lim Goh of SGI on Thursday, demonstrating their Ultraviolet systems. Very cool. While there are bigger and faster computers on the planet, they're all technically clusters rather than a single computer. The SGI machines can have 4096 CPUs and 16TB of RAM running under a single Linux kernel. Nice.

Also interesting to see the stats on when their systems were delivered to McLaren and Brawn, and where the performance of those cars was afterwards. I know there's more to F1 than CFD, but it certainly plays a large part these days.
